Background Acute bronchiolitis is the commonest cause of hospitalisation in infancy. Currently management consists of supportive care and oxygen. A Cochrane review concluded that, “nebulised 3 % saline may significantly reduce the length of hospital stay”. We conducted a systematic review of controlled trials of nebulised hypertonic saline (HS) for infants hospitalised with primary acute bronchiolitis. Methods Searches to January 2015 involved: Cochrane Central Register of Controlled Trials; Ovid MEDLINE; Embase; Google Scholar; Web of Science; and, a variety of trials registers. We hand searched Chest, Paediatrics and Journal of Paediatrics on 14 January 2015. Reference lists of eligible trial publications were checked. Randomised or quasi-randomised trials which compared HS versus either normal saline (+/− adjunct treatment) or no treatment were included. Eligible studies involved children less than 2 years old hospitalised due to the first episode of acute bronchiolitis. Two reviewers extracted data to calculate mean differences (MD) and 95 % Confidence Intervals (CIs) for length of hospital stay (LoS—primary outcome), Clinical Severity Score (CSS) and Serious Adverse Events (SAEs). Meta-analysis was undertaken using a fixed effect model, supplemented with additional sensitivity analyses. We investigated statistical heterogeneity using I 2 . Risk of bias, within and between studies, was assessed using the Cochrane tool, an outcome reporting bias checklist and a funnel plot. Results Fifteen trials were included in the systematic review ( n  = 1922), HS reduced mean LoS by 0.36, (95 % CI 0.50 to 0.22) days, but with considerable heterogeneity (I 2  = 78 %) and sensitivity to alternative analysis methods. A reduction in CSS was observed where assessed [ n  = 516; MD −1.36, CI −1.52, −1.20]. One trial reported one possible intervention related SAE, no other studies described intervention related SAEs. Conclusions There is disparity between the overall combined effect on LoS as compared with the negative results from the largest and most precise trials. Together with high levels of heterogeneity, this means that neither individual trials nor pooled estimates provide a firm evidence-base for routine use of HS in inpatient acute bronchiolitis.

As such, it may offer a potentially safe, effective and scalable intervention in those with Coronavirus Disease-19 (COVID-19) following infection with the betacoronavirus Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) [ 1 ]. ELVIS was undertaken in 66 adults with URTI. Results have been reported in detail elsewhere [ 2 ]. Briefly, volunteers with URTI were within 48 hours of symptom onset randomised to intervention (n = 32) or control (n = 34) arms. The intervention arm made hypertonic saline at home and performed HSNIG as many times as needed (maximum of 12 times/day). Control arm participants dealt with their URTI as they normally did. Nose swabs collected at recruitment and first thing in the morning on four consecutive days were sent to the laboratory for testing. Both arms kept a diary (which included the Wisconsin Upper Respiratory Symptom Survey-21 questionnaire) for a maximum of 14 days or until they were well for two consecutive days. Follow-up data were available for 92% of individuals (intervention arm: n = 30; control arm: n = 31). HSNIG reduced the duration of URTI by 1.9 days ( P  = 0.01), over-the-counter medication use by 36% ( P  = 0.004), transmission within household contacts by 35% ( P  = 0.006) and viral shedding by ≥0.5 log 10 /d ( P  = 0.04) in the intervention arm when compared to controls [ 2 ]. We also recently reported that epithelial cells mount an antiviral effect by producing hypochlorous acid (HOCl) from chloride ions [ 3 ]. HOCl is the active ingredient in bleach. Epithelial cells have this innate antiviral immune mechanism to clear viral infections. Since bleach is effective against all virus types [ 4 ], we tested to see if a range of DNA, RNA, enveloped and non-enveloped viruses were inhibited in the presence of chloride ions supplied via salt (NaCl). All the viruses we tested were inhibited in the presence of NaCl. The human viruses we tested were: DNA/enveloped: herpes simplex virus; RNA/enveloped: human coronavirus 229E (HCoV-229E), respiratory syncytial virus, influenza A virus; and RNA/non-enveloped: coxsackievirus B3 [ 3 ]. In COVID-19, high titres of SARS-CoV-2 are detectable in the upper respiratory tract of asymptomatic and symptomatic individuals [ 5 ]. The titres are higher in the nose than the throat suggesting measures that control the infection and viral shedding will help reduce transmission [ 5 ]. In the context of the COVID-19 pandemic, we have undertaken a post-hoc re-analysis of the ELVIS data with a focus on those infected with coronaviruses. Coronaviruses were the second most common cause of URTI (after rhinoviruses). Fifteen individuals were infected by a coronavirus: 7 in the intervention arm, 8 in the control arm. In the intervention arm, four participants were infected by an alphacoronavirus (HCoV 229E = 3, HCoV NL63 = 1) and three by a betacoronavirus (HCoV HKU1 = 3). In the control arm, two were

Phagocytes destroy ingested microbes by producing hypochlorous acid (HOCl) from chloride ions (Cl − ) and hydrogen peroxide within phagolysosomes, using the enzyme myeloperoxidase. HOCl, the active ingredient in bleach, has antibacterial/antiviral properties. As myeloperoxidase is needed for HOCl production, non-myeloid cells are considered incapable of producing HOCl. Here, we show that epithelial, fibroblast and hepatic cells have enhanced antiviral activity in the presence of increasing concentrations of sodium chloride (NaCl). Replication of enveloped/non-enveloped, DNA (herpes simplex virus-1, murine gammaherpesvirus 68) and RNA (respiratory syncytial virus, influenza A virus, human coronavirus 229E, coxsackievirus B3) viruses are inhibited in a dose-dependent manner. Whilst treatment with sodium channel inhibitors did not prevent NaCl-mediated virus inhibition, a chloride channel inhibitor reversed inhibition by NaCl, suggesting intracellular chloride is required for antiviral activity. Inhibition is also reversed in the presence of 4-aminobenzoic hydrazide, a myeloperoxidase inhibitor, suggesting epithelial cells have a peroxidase to convert Cl − to HOCl. A significant increase in intracellular HOCl production is seen early in infection. These data suggest that non-myeloid cells possess an innate antiviral mechanism dependent on the availability of Cl − to produce HOCl. Antiviral activity against a broad range of viral infections can be augmented by increasing availability of NaCl.

Resting neutrophils have a four- to five-fold higher intracellular Cl − concentration than expected for passive transfer 2 . Chloride transport across hydrophobic lipid membranes requires protein carriers such as chloride channels, anion-chloride exchangers or cation-chloride co-transporters 3 . Within phagosomes, myeloperoxidase (MPO) mediates the conversion of Cl − and hydrogen peroxide (H 2 O 2 ) to hypochlorous acid (HOCl) 1 .

Since numerous viruses cause URTI, antiviral therapy is impractical. As we have evidence of chloride-ion dependent innate antiviral response in epithelial cells, we conducted a pilot, non-blinded, randomised controlled trial of hypertonic saline nasal irrigation and gargling (HSNIG) vs standard care on healthy adults within 48 hours of URTI onset to assess recruitment (primary outcome). Acceptability, symptom duration and viral shedding were secondary outcomes. Participants maintained a symptom diary until well for two days or a maximum of 14 days and collected 5 sequential mid-turbinate swabs to measure viral shedding. The intervention arm prepared hypertonic saline and performed HSNIG. We recruited 68 participants (2.6 participants/week; November 2014-March 2015). A participant declined after randomisation. Another was on antibiotics and hence removed (Intervention:32, Control:34). Follow up data was available from 61 (Intervention:30, Control:31). 87% found HSNIG acceptable, 93% thought HSNIG made a difference to their symptoms. In the intervention arm, duration of illness was lower by 1.9 days (p = 0.01), over-the-counter medications (OTCM) use by 36% (p = 0.004), transmission within household contacts by 35% (p = 0.006) and viral shedding by ≥0.5 log 10 /day (p = 0.04). We hence need a larger trial to confirm our findings.

Adults and children get 2-3 and 6-7 attacks respectively of URTI annually 1 , 2 . In 2016 the UK lost 34.0 million work days (33.1% of total) due to minor illnesses such as URTI 3 . An episode of URTI cost €266.41, €273.36 in Cardiff and Southampton respectively 4 . In the US, 72% of respondents had URTI in the past year costing $40 billion annually 2 . Outbreaks of respiratory tract infections are common in hospitals and care homes with significant morbidity and mortality 5 . URTI can lead to lower respiratory tract infections (LRTI) such as pneumonia, or cause exacerbations in individuals with asthma, chronic obstructive pulmonary disease (COPD), and cystic fibrosis 6 . Since URTI precedes LRTI, early intervention could prevent these complications. At present, there are no antiviral agents to treat the common cold.

Most rhinovirus strains replicate better at the cooler temperatures found in the nasal cavity than at lung temperature, but the underlying mechanisms are not known. Using a mouse-adapted virus, we found that airway epithelial cells supporting rhinovirus replication initiate a more robust antiviral defense response through RIG-I–like receptor (RLR)–dependent interferon secretion and enhanced interferon responsiveness at lung temperature vs. nasal cavity temperature. Airway cells with genetic deficiencies in RLR or type I interferon receptor signaling supported much higher levels of viral replication at 37 °C. Thus, cooler temperatures can enable replication of the common cold virus, at least in part, by diminishing antiviral immune responses. Most isolates of human rhinovirus, the common cold virus, replicate more robustly at the cool temperatures found in the nasal cavity (33–35 °C) than at core body temperature (37 °C). To gain insight into the mechanism of temperature-dependent growth, we compared the transcriptional response of primary mouse airway epithelial cells infected with rhinovirus at 33 °C vs. 37 °C. Mouse airway cells infected with mouse-adapted rhinovirus 1B exhibited a striking enrichment in expression of antiviral defense response genes at 37 °C relative to 33 °C, which correlated with significantly higher expression levels of type I and type III IFN genes and IFN-stimulated genes (ISGs) at 37 °C. Temperature-dependent IFN induction in response to rhinovirus was dependent on the MAVS protein, a key signaling adaptor of the RIG-I–like receptors (RLRs). Stimulation of primary airway cells with the synthetic RLR ligand poly I:C led to greater IFN induction at 37 °C relative to 33 °C at early time points poststimulation and to a sustained increase in the induction of ISGs at 37 °C relative to 33 °C. Recombinant type I IFN also stimulated more robust induction of ISGs at 37 °C than at 33 °C. Genetic deficiency of MAVS or the type I IFN receptor in infected airway cells permitted higher levels of viral replication, particularly at 37 °C, and partially rescued the temperature-dependent growth phenotype. These findings demonstrate that in mouse airway cells, rhinovirus replicates preferentially at nasal cavity temperature due, in part, to a less efficient antiviral defense response of infected cells at cool temperature. rhinovirus common cold airway RIG-I innate immunity HHS | NIH | National Institute of Allergy and Infectious Diseases (NIAID) 100000060 AI054359 HHS | NIH | National Institute of Allergy and Infectious Diseases (NIAID) 100000060 AI064705 Howard Hughes Medical Institute (HHMI) 100000011 Investigator award pmc-stat

The immune system's protection against invasive microorganisms and other biological functions in living things depend heavily on hypochlorous acid (HOCl). For the sensitive detection of HOCl, a turn-on fluorescent probe (W-HOCl) has been developed. The probe is well characterized by 1 HNMR, 13 CNMR, FTIR and HRMS. Through the oxidation of sulfide to sulfoxide caused by HOCl, the probe quickly identifies HOCl. The fluorescence was enhanced 42 times as a result of the reaction between W-HOCl and HOCl. The probe has excellent photophysical properties along with a detection limit as low as 6 nM. The imaging of HOCl in living cells showed the probe's potential as an HOCl biosensor. Therefore, the probe is predicted to be useful for the accurate detection of HOCl in complex biosystems. The immune system's protection against invasive microorganisms and other biological functions in living things depend heavily on hypochlorous acid (HOCl).

Introduction In recent years, there has been growing interest in the function of anions in biology, industry, medicine, and the environment. Anion sensors with remarkable design and synthesis capabilities have attracted the attention of experts in inorganic catalysis, pharmaceutical synthesis, environmental analysis, and life sciences. Many fluorescent sensors have been reported for visualizing viscosity in dysfunction, inflammation, and Alzheimer's disease, and an allosteric hairpin switch-based isothermal amplification strategy for sensitive detection of bacterial detection. 1–3 Hypochlorous acid (HOCl)/hypochlorite (ClO − ) is a very active oxidation species that is essential for both environmental safety and biomedicine. 4,5 As is well known, we utilize HOCl to disinfect and purify water in our daily lives by getting rid of bacteria. Myeloperoxidase (MPO) catalyzes the reaction of hydrogen peroxide with chloride ions to form HOCl in biological systems. 6 It is essential for preserving the intracellular redox equilibrium, reducing inflammation, and fending off infections. 7,8 However, too much HOCl can result in the production of dangerous substances in water (such as trihalomethanes) and cause a number of oxidative stress-related illnesses in people, such as cancer, arthritis, cardiovascular disease, and neurodegeneration. In living things, highly active HOCl can aid in the chemical alteration and destruction of a variety of biomolecules, such as proteins, lipids, and nucleic acids. 9–14 Thus, it is necessary to develop an efficient technique for the real-time detection of HOCl/ClO in biological and environmental systems. Small-molecule fluorescent probes are highly sensitive, noninvasive, and detect in real time, they have attracted a lot of interest. 15–26 Using p -methoxyphenol as the recognition group, Yang's group discovered in 2008 that hypochlorous acid could be specifically detected in a variety of RO

CFTR is expressed in immune cells and regulates innate immunity, both directly and indirectly. The epithelial sodium channel (ENaC) contributes to dysfunction in CF airway epithelial cells. However, the impact of non-CFTR ion channel dysfunction on CF immune responses is not understood. Improved understanding of how immune function is regulated by ion channels may allow antibiotic- and mutation-agnostic treatment approaches to chronic infection and inflammation. Therefore, we hypothesized that ENaC is aberrantly expressed in CF macrophages and directly contributes to impaired phagocytic and inflammatory functions. ENaC expression was characterized in immune cells isolated from CF and non-CF blood donors. Monocyte-derived macrophage (MDM) function and bacterial killing was tested with ENaC modulation. Baseline ENaC expression in human CF MDMs, lymphocytes, and granulocytes was increased at both the transcript and protein level relative to non-CF and persisted after infection. CFTR inhibition in non-CF MDMs resulted in ENaC overexpression. CFTR modulator treatment reduced but did not eliminate ENaC overexpression in CF MDMs. Interestingly, ENaC inhibition increased CFTR expression. Amiloride-treated CF MDMs also showed normalized ROS production, improved autophagy, and decreased pro-inflammatory cytokine production. Sodium channel expression in CF MDMs normalized after Amiloride treatment with minimal effect on other ion channels. In summary, ENaC modulation in immune cells is a novel potential therapeutic target for CF infection control, either in combination with CFTR modulators, or as a sole agent for people not eligible for CFTR modulators.

Type I IFN production and signaling in macrophages play critical roles in innate immune responses. High salt ( i.e. high concentrations of NaCl) has been proposed to be an important environmental factor that influences immune responses in multiple ways. However, it remains unknown whether high salt regulates type I IFN production and signaling in macrophages. Here, we demonstrated that high salt promoted IFNβ production and its signaling in both human and mouse macrophages, and consequentially primed macrophages for strengthened immune sensing and signaling when challenged with viruses or viral nucleic acid analogues. Using both pharmacological inhibitors and RNA interference we showed that these effects of high salt on IFNβ signaling were mediated by the p38 MAPK/ATF2/AP1 signaling pathway. Consistently, high salt increased resistance to vesicle stomatitis virus (VSV) infection in vitro. In vivo data indicated that a high-salt diet protected mice from lethal VSV infection. Taken together, these results identify high salt as a crucial regulator of type I IFN production and signaling, shedding important new light on the regulation of innate immune responses. interferon macrophage p38 MAPK viral immunology virus High salt High salt type I interferon macrophage virus p38 MAPK high salt type I interferon pmc-status-qastatus 0 pmc-status-live yes pmc-status-embargo no pmc-status-released yes pmc-prop-open-access no pmc-prop-olf no pmc-prop-manuscript no pmc-prop-legally-suppressed no pmc-prop-has-pdf yes pmc-prop-has-supplement yes pmc-prop-pdf-only no pmc-prop-suppress-copyright no pmc-prop-is-real-version no pmc-prop-is-scanned-article no pmc-prop-preprint no pmc-prop-in-epmc yes

The other components include epithelial ion transporters, which mediate the secretion of the oxidizable anion thiocyanate (SCN − ) into airway surface liquid, and lactoperoxidase (LPO), which catalyzes the H 2 O 2 -dependent oxidation of the pseudohalide SCN − to yield the antimicrobial molecule hypothiocyanite (OSCN − ). We hypothesized that this oxidative host defense system is also active against respiratory viruses. We evaluated the activity of oxidized LPO substrates against encapsidated and enveloped viruses. When tested for antiviral properties, the LPO-dependent production of OSCN − did not inactivate adenovirus or respiratory syncytial virus (RSV). However, substituting SCN − with the alternative LPO substrate iodide (I − ) resulted in a marked reduction of both adenovirus transduction and RSV titer. Importantly, well-differentiated primary airway epithelia generated sufficient H 2 O 2 to inactivate adenovirus or RSV when LPO and I − were supplied. The administration of a single dose of 130 mg of oral potassium iodide to human subjects increased serum I − concentrations, and resulted in the accumulation of I − in upper airway secretions. These results suggest that the LPO/I − /H 2 O 2 system can contribute to airway antiviral defenses. Furthermore, the delivery of I − to the airway mucosa may augment innate antiviral immunity.

Microalgae represent sustainable sources of bioactive compounds with potential health benefits. This study conducted a comprehensive proteomic analysis of Tetraselmis chuii ( T. chuii ) biomass to identify proteins capable of generating bioactive peptides (BAPs) through simulated orogastric digestion. In silico digestion and bioinformatic predictions indicated the release of antioxidant, anti-inflammatory, and antibacterial peptides. Molecular docking demonstrated strong interactions with targets implicated in oxidative stress, inflammation, and Helicobacter pylori ( H. pylori ) virulence. Biochemical assays and cell-based models confirmed antioxidant and anti-inflammatory activities in both the biomass and its digest, although no significant antibacterial effect against H. pylori was observed under the tested conditions. Considering the role of chronic inflammation in H. pylori -associated pathologies, these findings suggest that T. chuii may serve as a candidate for mitigating tissue damage driven by oxidative and inflammatory stress. Further research is required to address compound stability and optimize delivery strategies. microalgae Tetraselmis chuii bioactive peptides in silico digestion Helicobacter pylori Project PID2021-122989OB-I00 MICIU/AEI/10.13039/501100011033 FEDER, EU, Project ILINK24023 Spanish National Research Council CYTED 124RT0164 CM PIPF-2022/BIO-24996 This work was supported through Project PID2021-122989OB-I00, financed by MICIU/AEI/10.13039/501100011033 and FEDER, EU, Project ILINK24023 financed by the Spanish National Research Council (CSIC.

Aims Myeloperoxidase activity can contribute to impaired vascular endothelial function and fibrosis in chronic inflammation‐related cardiovascular disease. Here, we investigated the safety, tolerability and pharmacokinetics of the myeloperoxidase inhibitor, AZD4831. Methods In this randomized, single‐blind, placebo‐controlled, phase I, first‐in‐human study, healthy men in five sequential cohorts were randomized 3:1 to receive a single oral dose of AZD4831 (5, 15, 45, 135 or 405 mg) or placebo, after overnight fasting. After at least 7 days' washout, one cohort additionally received AZD4831 45 mg after a high‐calorie meal. Results Forty men participated in the study (eight per cohort: AZD4831, n  = 6; placebo, n  = 2). AZD4831 distributed rapidly into plasma, with a half‐life of 38.2–50.0 hours. The area under the plasma concentration–time curve (AUC) increased proportionally with dose (AUC 0–∝ slope estimate 1.060; 95% confidence interval [CI] 0.9943, 1.127). Increases in maximum plasma concentration were slightly more than dose proportional (slope estimate 1.201; 95% CI 1.071, 1.332). Food intake reduced AZD4831 absorption rate but did not substantially affect overall exposure or plasma half‐life ( n  = 4). Serum uric acid concentrations decreased by 71.77 (95% CI 29.15, 114.39) and 84.42 (58.90, 109.94) μmol L −1 with AZD4831 135 mg and 405 mg, respectively. Maculopapular rash (moderate intensity) occurred in 4/30 participants receiving AZD4831 (13.3%). No other safety concerns were identified. Conclusions AZD4831 was generally well tolerated, rapidly absorbed, had a long plasma half‐life and lowered uric acid concentrations after single oral doses in healthy men. These findings support the further clinical development of AZD4831. cardiovascular disease myeloperoxidase phase I clinical trial AstraZeneca pmc-status-qastatus 0 pmc-status-live yes pmc-status-embargo no pmc-status-released yes pmc-prop-open-access yes pmc-prop-olf no pmc-prop-manuscript no pmc-prop-legally-suppressed no pmc-prop-has-pdf yes pmc-prop-has-supplement yes pmc-prop-pdf-only no pmc-prop-suppress-copyright no pmc-prop-is-real-version no pmc-prop-is-scanned-article no pmc-prop-preprint no pmc-prop-in-epmc yes pmc-license-ref CC BY source-schema-version-number 2.0 component-id bcp13855 cover-date April 2019 details-of-publishers-convertor Converter:WILEY_ML3GV2_TO_NLMPMC version:5.6.1 mode:remove_FC converted:18.03.2019 Gan L‐M , Lagerström‐Fermér M , Ericsson H , et al.

In this comparative study, serum complement system antimicrobial activity was measured from 159 serum samples, taken from individuals from microbe-damaged (70 samples) and from reference buildings (89 samples). Antimicrobial activity was assessed using a probe-based bacterial Escherichia coli -lux bioluminescence system and comparison was made at a group level between the experimental and reference group. The complement activity was higher in users of microbe-damaged buildings compared with the reference group and the significant ( P  < 0.001) increase in activity was found in the classical reaction pathway. This study strengthens our notion that exposure to indoor-related microbe damage increases the risk for systemic subclinical inflammation and creates a health risk for building users.

Moreover, complement participates in Ab responses by augmenting their effects and this complementation is the basis for its name. 1 – 3 Finally, the complement system plays a critical role in immune system clearance and in immune complex formation. Complement functions are a fundamental part of the inflammatory process, and because these functions are able to occur in the absence of infection, the continuous, uncontrollable, and excessive activity constitutes a risk for the host in the form of autoimmune diseases and tissue destruction. The complement system includes three separate reaction pathways ( Figure 1 ). The classical activation pathway augments the effects of Abs and is a link connecting the adaptive and innate systems. The main activators are the IgG-class Abs, but also the less specific IgM-pentamer molecules can launch the cascade. 1 – 3 Acute phase effectors such as C-reactive protein and amylase are known to directly activate the classical pathway. 5 The lectin pathway is similar to the classical pathway, but the activation is less specific through the recognition of

Hypertonic saline enhances mucociliary clearance and may lessen the destructive inflammatory process in the airways. This is an update of a previously published review. Objectives To investigate efficacy and tolerability of treatment with nebulised hypertonic saline on people with CF compared to placebo and or other treatments that enhance mucociliary clearance. Search methods We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group's Cystic Fibrosis Trials Register, comprising references identified from comprehensive electronic database searches, handsearches of relevant journals and abstract books of conference proceedings. We also searched ongoing trials databases. Date of most recent searches: 08 August 2018. Selection criteria Randomised and quasi‐randomised controlled trials assessing hypertonic saline compared to placebo or other mucolytic therapy, for any duration or dose regimen in people with CF (any age or disease severity). Data collection and analysis Two authors independently reviewed all identified trials and data, and assessed trial quality. The quality of the evidence was assessed using GRADE. Main results A total of 17 trials (966 participants, aged 4 months to 63 years) were included; 19 trials were excluded, three trials are ongoing and 16 are awaiting classification. We judged 14 of the 17 included trials to have a high risk of bias due to participants ability to discern the taste of the solutions. Hypertonic saline 3% to 7% versus placebo At four weeks, we found very low‐quality evidence from three placebo‐controlled trials (n = 225) that hypertonic saline (3% to 7%, 10 mL twice‐daily) increased the mean change from baseline of the forced expiratory volume at one second (FEV 1 ) (% predicted) by 3.44% (95% confidence interval (CI) 0.67 to 6.21), but there was no difference between groups in lung clearance index in one small trial (n = 10). By 48 weeks the effect was slightly smaller in one trial (n = 134), 2.31% (95% CI ‐2.72 to 7.34) (low‐quality evidence). No deaths occurred in the trials. Two trials reporting data on exacerbations were not combined as the age difference between the participants in the trials was too great . One trial (162 adults) found 0.5 fewer exacerbations requiring antibiotics per person in the hypertonic saline group; the second trial (243 children, average age of two years) found no difference between groups (low‐quality evidence). There was insufficient evidence reported across the trials to determine the rate of different adverse events such as cough, chest tightness, tonsillitis and vomiting (very low‐quality evidence). Four trials (n = 80) found very low‐quality evidence that sputum clearance was better with hypertonic saline. A further trial was performed in adults with an acute exacerbation of lung disease (n = 132). The effects of hypertonic saline on short‐term lung function, 5.10% higher (14.67% lower to 24.87% higher) and the time to the subsequent exacerbation post‐discharge, hazard ratio 0.86 (95% CI 0.57 to 1.30) are uncertain (low‐quality evidence). No deaths were reported. Cough and wheeze were reported but no serious adverse events (very low‐quality evidence). Hypertonic saline versus mucus mobilising treatments Three trials compared a similar dose of hypertonic saline to recombinant deoxyribonuclease (rhDNase); two (61 participants) provided data for inclusion in the review. There was insufficient evidence from one three

Hyperosmolarity of the airway surface liquid (ASL) has been proposed as the stimulus for hyperpnoea-induced asthma. We found previously that mucociliary clearance (MCC) was increased after isocapnic hyperventilation (ISH) with dry air, and we proposed that the increase related to transient hyperosmolarity of the ASL. We investigated the effect of increasing the osmolarity of the ASL on MCC, by administering an aerosol of concentrated salt solution. MCC was measured using 99mTc-sulphur colloid, g...

In recent years, numerous pathways were explored in the pathogenesis of COPD in the quest for new potential therapeutic targets for more personalised medical care. In this context, the study of the cystic fibrosis transmembrane conductance regulator (CFTR) began to gain importance, especially since the advent of the new CFTR modulators which had the potential to correct this protein’s dysfunction in COPD. The CFTR is an ion transporter that regulates the hydration and viscosity of mucous secretions in the airway. Therefore, its abnormal function favours the accumulation of thicker and more viscous secretions, reduces the periciliary layer and mucociliary clearance, and produces inflammation in the airway, as a consequence of a bronchial infection by both bacteria and viruses. Identifying CFTR dysfunction in the context of COPD pathogenesis is key to fully understanding its role in the complex pathophysiology of COPD and the potential of the different therapeutic approaches proposed to overcome this dysfunction. In particular, the potential of the rehydration of mucus and the role of antioxidants and phosphodiesterase inhibitors should be discussed. Additionally, the modulatory drugs which enhance or restore decreased levels of the protein CFTR were recently described. In particular, two CFTR potentiators, ivacaftor and icenticaftor, were explored in COPD. The present review updated the pathophysiology of the complex role of CFTR in COPD and the therapeutic options which could be explored. cystic fibrosis transmembrane conductance regulator COPD CFTR modulators ivacaftor icenticaftor pmc-status-qastatus 0 pmc-status-live yes pmc-status-embargo no pmc-status-released yes pmc-prop-open-access yes pmc-prop-olf no pmc-prop-manuscript no pmc-prop-legally-suppressed no pmc-prop-has-pdf yes pmc-prop-has-supplement no pmc-prop-pdf-only no pmc-prop-suppress-copyright no pmc-prop-is-real-version no pmc-prop-is-scanned-article no pmc-prop-preprint no pmc-prop-in-epmc yes pmc-license-ref CC BY 1. Introduction Despite the considerable advances made in recent years, the mechanisms underlying the onset, pathogenesis and symptomatic development of chronic obstructive pulmonary disease (COPD) remain largely unknown. Although we know that prolonged exposure to tobacco smoke and other inhaled toxins (e.g., biomass [ 1 ], and occupational smokes [ 2 ]) is the main risk factor for the disease, not all patients exposed to tobacco smoke develop this clinical condition. Furthermore, even among those who do develop COPD, the clinical, functional and prognostic impact varies among patients and the conditioning factors of this different evolution are equally unknown [ 3 , 4 ]. In this context, the search for pathogenetic pathways that help us understand the biological pathways that cause COPD, and which determine its clinical impact, constitute the current challenges in the biomedical research of this disease [ 5 ]. In recent decades, numerous pathways were explored that we now know play an important role in the pathogenesis of COPD, including protease–antiprotease imbalance, oxidative and nitrosative stress, inflammatory mechanisms associated with alterations in innate and acquired immunity, and apoptosis or autoimmunity phenomena [ 6 ]. However, despite all these efforts, the factor which defines the patients who will develop COPD when exposed to tobacco still eludes us. For t

ABSTRACT Salt mines are often used for halotherapy against lung and skin diseases. In addition to salt, they also contain various types of microorganisms, which remain poorly characterised. Here, we examined culturable halophilic and non‐halophilic microbial populations in relation to the physico‐chemical characteristics in the air of four different sites of the Bochnia Salt Mine, a popular halotherapy resort in Southern Poland. At the mine entrance, the temperature was highest (20.8°C) and decreased with increasing distance from the entrance (15.5°C at 2671 m from entrance), while humidity increased from 55.9% to 77.0%, as did the NaCl concentration. At the entrance, non‐halophilic microorganisms prevailed, especially fungi that grew at 21°C. Halophiles gradually dominated with distance from the entrance, including halophilic archaea that grew at 28°C or 37°C on medium containing 15%, 20%, or 25% NaCl. Seven halophilic archaeal species were identified by 16S rRNA gene sequencing. The frequency of non‐halophiles was inversely related to distance from the entrance, humidity, and presence of ions, while the reverse was seen for halophiles. An exception was the site used for halotherapy, where non‐halophilic bacteria dominated. Thus, natural salt mines contain a wide variety of non‐halophilic and halophilic microorganisms, including archaea, which may contribute to the halotherapeutic effects. This study unveils the presence and densities of cultivable halophilic and non‐halophilic microorganisms present in the air sampled at four different sites of the Bochnia Salt Mine in Poland used for halotherapy. It highlights for the first time the presence of cultivable halophilic archaea in salt mine air in relation to the physico‐chemical characteristics of the aerosols and human activity during the summer season.

Abstract Objective To characterize postoperative airway obstruction and evaluate management strategies in pediatric patients with cleft palate following tissue‐augmentation palatoplasty (TAP). Study Design Retrospective case series. Setting Single academic center. Methods Patients with obstruction within 1 year of primary TAP between 2017 and 2023 were identified. Fisher's exact, Wilcoxon rank‐sum, and Spearman rank correlation were used to investigate the relationship between TAP type, obstruction severity, interventions, and polysomnography (PSG) findings (Obstructive Apnea‐Hypopnea Index [OAHI], total Apnea‐Hypopnea Index [AHI]) and disposition details. Results Of the 129 patients who underwent primary TAP, 25 patients developed obstructive symptoms (19.4%); 52% female, 32% syndromic. In total, 17 underwent surgical intervention for obstruction (68.0%): revision palatoplasty/flap revision (8/25, 35%), tonsillectomy and partial cephalic adenoidectomy (10/25, 40%), and partial cephalic adenoidectomy only (5/25, 20%). In total, 11 were medically managed and 3 were observed without intervention. In nine patients with paired PSGs, there was no difference in pre‐TAP and post‐TAP AHI or OAHI. Patients who underwent surgical revision had worse pre‐TAP AHI compared to those who did not undergo surgical revision (mean ± SD: 15.7 ± 5.9 vs 6.2 ± 4.1, P  = .01). Conclusion TAP is a newer surgical technique used to address tissue deficiency in cleft palate repair. Most patients who experienced postoperative obstruction following TAP ultimately required surgical intervention, though preoperative AHI may help identify those at higher risk for obstruction. Future studies are necessary to evaluate the efficacy of earlier interventions and elucidate factors impacting obstruction risk and symptom resolution. airway obstruction cleft palate pediatrics polysomnography tissue‐augmentation palatoplasty pmc-status-qastatus 0 pmc-status-live yes pmc-status-embargo no pmc-status-released yes pmc-prop-open-access yes pmc-prop-olf no pmc-prop-manuscript no pmc-prop-legally-suppressed no pmc-prop-has-pdf yes pmc-prop-has-supplement no pmc-prop-pdf-only no pmc-prop-suppress-copyright no pmc-prop-is-real-version no pmc-prop-is-scanned-article no pmc-prop-preprint no pmc-prop-in-epmc yes source-schema-version-number 2.0 cover-date October 2025 details-of-publishers-convertor Converter:WILEY_ML3GV2_TO_JATSPMC version:6.6.4 mode:remove_FC converted:25.09.2025 This article was presented at the AAO‐HNSF 2024 Annual Meeting & OTO EXPO; September 27–October 1, 2024; Miami Beach, Florida. Orofacial clefts are the most common human craniofacial congenital anomaly, significantly impacting speech mechanics due to palatal defects and abnormal orientation of the levator veli palatini (LVP) muscle. 1 , 2 This leads to velopharyngeal dysfunction (VPD) and reduced speech quality. Palatoplasty is performed to close the palatal defect, with the Furlow double‐opposing Z‐plasty or straight‐line techniques with intravelar veloplasty being the current standards. However, traditional palatoplasty may not fully address the tissue deficiency inherent to orofacial clefts, leading to complications such as dehiscence, scarring, oronasal fistula formation, and V

This is an update of a previously published review. Objectives To investigate efficacy and tolerability of nebulised hypertonic saline treatment in people with cystic fibrosis (CF) compared to placebo or other treatments that enhance mucociliary clearance. Search methods We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group's Cystic Fibrosis Trials Register, comprising references identified from comprehensive electronic database searches, handsearches of relevant journals and abstract books of conference proceedings. We also searched ongoing trials databases. Most recent search: 25 April 2022. Selection criteria We included randomised and quasi‐randomised controlled trials assessing hypertonic saline compared to placebo or other mucolytic therapy, for any duration or dose regimen in people with CF (any age or disease severity). Data collection and analysis Two authors independently reviewed all identified trials and data, and assessed trial quality. We assessed the certainty of the evidence using GRADE. For cross‐over trials we stipulated a one‐week washout period. We planned to use results from a paired analysis in the review, but this was only possible in one trial. For other cross‐over trials, we chose to treat the trials as if they were parallel. Main results We included 24 trials (1318 participants, aged one month to 56 years); we excluded 29 trials, two trials are ongoing and six are awaiting classification. We judged 15 of the 24 included trials to have a high risk of bias due to participants' ability to discern the taste of the solutions. Hypertonic saline 3% to 7% versus placebo (stable disease) We are uncertain whether the regular use of nebulised hypertonic saline in stable lung disease leads to an improvement in forced expiratory volume in one second (FEV 1 ) % predicted at four weeks, (mean difference (MD) 3.30%, 95% confidence interval (CI) 0.71 to 5.89; 4 trials, 246 participants; very low‐certainty evidence). In preschool children we found no difference in lung clearance index (LCI) at four weeks, but a small improvement after 48 weeks of treatment with hypertonic saline compared to isotonic saline (MD ‐0.60, 95% CI ‐1.00 to ‐0.19; 2 trials, 192 participants). We are also uncertain whether hypertonic saline made a difference to mucociliary clearance, pulmonary exacerbations or adverse events compared to placebo. Hypertonic saline versus control (acute exacerbation) Two trials compared hypertonic saline to control, but only one provided data. There may be little or no difference in lung function measured by FEV 1 % predicted after hypertonic saline compared to isotonic saline (MD 5.10%, 95% CI ‐14.67 to 24.87; 1 trial, 130 participants). Neither trial reported any deaths or measures of sputum clearance. There were no serious adverse events. Hypertonic saline versus rhDNase Three trials compared a similar dose of hypertonic saline to recombinant deoxyribonuclease (rhDNase); two trials (61 participants) provided data for inclusion in the review. We are uncertain whether there was an effect of hypertonic saline on FEV 1 % predicted after three weeks (MD 1.60%, 95% CI ‐7.96 to 11.16; 1 trial, 14 participants; very low‐certainty evidence). At three months, rhDNase may lead to a greater increase in FEV 1 % predicted than hypertonic saline (5 mL twice daily) at 12 weeks

The first and last halochamber are the ones recommended for cardio–respiratory, immuno–thyroid and osteo–muscular conditions, as well as in psycho–motor disorders. Based on questionnaires carried out over the course of a year, between 1 September 2021–31 August 2022, in two periods of stationing/treatment: a cold one (15 September 2021–15 December 2021) and a warm one (1 May 2022–30 July 2022), correlated with the data from the Salina medical office, achieved the profile of the improvement rate of the patients’ ailments depending on the type of treatment (working regime in halochambers). These studies have allowed the optimization of the treatment conditions in the artificial surface halochambers in order to reduce the stationary period and optimize the treatment cycles.

Cigarette smoke promotes the occurrence of inflammation, oxidative stress, and pyroptosis. Halotherapy has been shown to dilute secretions in the airways and promote drainage, but the mechanism remains unclear. In this study, we evaluated the anti-inflammatory and antioxidant effects of halotherapy in COPD rats and investigated the underlying mechanism. Methods A COPD rat model was constructed by cigarette smoke and lipopolysaccharide tracheal instillation. A total of 120 male Sprague-Dawley (SD) rats were randomly divided into control, model, halotherapy, terbutaline, halotherapy + terbutaline, and Ac-YVAD-CMK (Caspase-1 inhibitor) groups. After modeling and treatment, the pulmonary function of the rats was measured. Pathological changes in the lungs were measured by hematoxylin-eosin (H&E) staining. Serum interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), interleukin-4 (IL-4), and nitric oxide (NO) levels were determined using enzyme-linked immunosorbent assay (ELISA) kits. Malondialdehyde (MDA) levels and superoxide dismutase (SOD) activity in the lungs were determined by biochemical tests. The levels of cluster of differentiation 4 (CD4 + ) and CD8 + T cells in the blood were determined by flow cytometry. The expression levels of Toll-like receptor 4 (TLR4), nuclear factor kappa B (NF-κB), gasdermin-D (GSDMD), nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3), apoptosis-associated speck-like protein containing a C-terminal caspase recruitment domain (ASC), Caspase-1, and IL-1β in lung tissues were detected by immunohistochemistry, Western blotting, or quantitative polymerase chain reaction (qPCR). Results Halotherapy recovered the clinical symptoms of COPD rats, and reduced lung inflammatory cell infiltration and air wall attenuation. It also relieved oxidative stress in the lung tissue of COPD rats, reduced CD4 + and CD8 + T cell accumulation in lung tissue, and decreased inflammatory factor production in the serum of COPD rats. Furthermore, it inhibited the TLR4/NF-κB/GSDMD and NLRP3/ASC/Caspase-1 signaling pathways. Ac-YVAD-CMK could not completely inhibit the therapeutic effect of halotherapy on COPD rats. Conclusions Halotherapy improves lung function by inhibiting the NLRP3/ASC/Caspase-1 signaling pathway to reduce inflammation and pyroptosis in COPD rats, and may be a new option fo

Halotherapy (HT), derived from speleotherapy in salt mines, is also a drug-free therapeutic method. HT effects vary depending on the therapeutic method and the structure of halotherapy environment. The purpose of this article is to show the HT effects of “halotherapy chamber with artificial salt-mine environment” of the National Institute of Rehabilitation, Physical Medicine and Balneoclimatology (INRMFB), on patients with bronchial asthma and other chronic, infectious-inflammatory and allergic respiratory diseases, describing the clinical effects on certain nonspecific resistance factors, on markers of inflammatory processes and on certain immunological changes. Patients were clinically assessed, with the application of hematologic investigations, analysis of nonspecific resistance to infection and of inflammatory process markers, immunologic assessments, analysis of sodium and potassium concentrations, of mineralocorticoid function and other biochemical tests. For the experimental HT therapy performed in the “halotherapy chamber with artificial salt-mine environment” of INRMFB, 15 patients suffering from bronchial asthma, allergic rhinitis, chronic bronchitis, chronic obstructive bronchopneumopathy were selected, based on specific medical indications and contraindications and applying ethical principles, as well as 4 patients with similar pathologies for the control group, who underwent in-home drug treatment. After the specific halotherapy treatment on patients with bronchial asthma, chronic bronchitis and chronic obstructive bronchopneumopathy, which also showed other chronic, infectious-inflammatory and allergic respiratory pathologies, triggering of anti-inflammatory (and also anti allergic) mechanisms and healing effects on inflammatory process were noted. Data acquired also proved the halo therapeutic effect causing the reduction of sensitiveness of body in patients with bronchial asthma.

Following the “survey for the innovative use of potentially therapeutic salt-mine environment factors, in health and balneoclimateric tourism; modeling solutions”, the conceptual model was elaborated, subsequently converted into an experimental functional model entitled “halotherapy chamber with artificial salt-mine environment”, destined for surface halotherapy and built within the National Institute of Rehabilitation, Physical Medicine and Balneoclimatology. This model was followed by surveys in the underground salt-mine environment, destined to assess the presence and quality of factors with speleotherapeutic / halotherapeutic potential, medical-biological multi-discipline surveys, including organismic and cellular-level analysis, before and after the experimental halotherapy treatment, on lab animals – Wistar rats with pathology experimentally induced by sensitization with ovalbumin.

Objectives : Pseudomonas aeruginosa is an opportunistic pathogen of high clinical relevance due to its ability to form biofilms, its inherent virulence regulated by quorum-sensing systems, and its multidrug resistance. In the present study, we evaluated the inhibitory potential of nine extracts from Inula species (chloroform and methanolic fractions, including a sesquiterpene lactone-enriched fraction) against biofilm formation and virulence-associated traits of P. aeruginosa PAO1 and three multidrug-resistant clinical isolates, as well as their cytotoxicity, biocompatibility, and ability to affect cytokine and nitric oxide production in infected skin explants. Methods : The following methods were applied: fractionation and extraction of plant extracts; cytotoxicity assessment on HFF cells; crystal violet assay for determining antibiofilm activity; fluorescence microscopy for evaluating biofilm viability; electron microscopy for assessing the 3D structure of biofilms and morphological alterations; inhibition assays of pyocyanin pigment, protease activity, bacterial motility, interleukin-17, and nitric oxide production; histological analysis of mouse skin explants. Results : Quantitative analyses of antibiofilm activity revealed that five of the tested extracts inhibited biofilm formation by more than 50%. Structural and functional analyses using confocal laser scanning microscopy and scanning electron microscopy demonstrated a substantial reduction in biofilm thickness, exfoliation of biofilm biomass, the presence of isolated bacterial clusters, metabolically inactive cell populations, and morphological abnormalities associated with cell elongation, invagin

Nasal irrigation (NI) is an effective, safe, low-cost strategy for treating and preventing upper respiratory tract diseases. High-volume, low-pressure saline irrigations are the most efficient method for removing infectious agents, allergens, and inflammatory mediators. This article reviews clinical evidence supporting NI use in various conditions: nasal congestion in infants, recurrent respiratory infections, acute and chronic rhinosinusitis, allergic and gestational rhinitis, empty nose syndrome, and post-endoscopic sinus surgery care. NI improves symptoms, reduces recurrence, enhances the efficacy of topical drugs, and decreases the need for antibiotics and decongestants. During the COVID-19 pandemic, NI has also been explored as a complementary measure to reduce viral load. Due to the safe profile and mechanical cleansing action on inflammatory mucus, nasal irrigations represent a valuable adjunctive treatment across a wide range of sinonasal conditions. nasal irrigation upper respiratory tract infections mechanical cleansing viral load reduction sinonasal disorders This research received no external funding. pmc-status-qastatus 0 pmc-status-live yes pmc-status-embargo no pmc-status-released yes pmc-prop-open-access yes pmc-prop-olf no pmc-prop-manuscript no pmc-prop-legally-suppressed no pmc-prop-has-pdf yes pmc-prop-has-supplement no pmc-prop-pdf-only no pmc-prop-suppress-copyright no pmc-prop-is-real-version no pmc-prop-is-scanned-article no pmc-prop-preprint no pmc-prop-in-epmc yes 1. Introduction Nasal irrigation (NI) is an ancient healing practice of the upper respiratory tract that originated in the medical tradition from the ancient Hindu practice of Ayurveda, whose roots go back to the Vedas, a thousand years before Christ. Historically, “Neti” is an integral part of the yogic system of body cleansing techniques [ 1 ]. It is primarily intended to cleanse the first airways, the nose, throat, and pharynx, and has been used for thousands of years to relieve rhinosinusitis and allergy symptoms. The two main variants of Neti are those which use water poured into a nostril so that it comes out of the nostril against the side, and the more advanced sutra neti. “Sutra Neti” represents an alternative NI. It consists of a piece of wet string inserted through the nose into the mouth; holding both ends simultaneously, the string is alternately pulled in and out of the nose and pulled out of the mouth at the end of the procedure. Both techniques are used to rinse the nasal cavities, using gravity to make the water flow through the nose [ 2 ]. NI was introduced into Western medicine at the beginning of the 19th century [ 3 ] and has continued to gain popularity worldwide [ 4 ]. It is used alone or with other therapies in various conditions, including acute and chronic rhinosinusitis [ 5 , 6 , 7 , 8 ] and allergic rhinitis [ 9 , 10 ]. Furthermore, especially in children, it is prescribed to treat and prevent upper respiratory tract infections [ 11 ]. In general, otorhinolaryngologists and paediatricians play a crucial role in adopting NI as they consider it very effective. It is associated with significantly reducing the signs and symptoms of rhinosinus pathologies and prescribing drugs commonly used in these conditions [ 11 , 12 ]. Their endorsement and recommendation of NI can dramatically influence its acceptance and use in clinical prac

Background Chronic obstructive pulmonary disease (COPD) is a chronic, progressive disease and is treated with inhaled medication to optimize the patient’s lung health through decreasing their symptoms, especially breathlessness. Halotherapy is the inhalation of micronized dry salt within a chamber that mimics a salt cave environment. Recent media reports suggest that this therapy may help with the symptoms of COPD. Objective To critically evaluate and summarize the evidence for the use of halotherapy as a treatment for COPD. Design A review using systematic approach and narrative synthesis. Data sources Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, MEDLINE, EMBASE, CINAHL, and Google Scholar were searched. Two reviewers independently reviewed abstracts and selected eligible studies based on predetermined selection criteria. Results Of the 151 articles retrieved from databases and relevant reference lists, only one randomized controlled trial met the inclusion criteria. A meta-analysis was unable to be conducted due to the limited number of published studies. Inclusion criteria were subsequently expanded to allow three case-control studies to be included, ensuring that a narrative synthesis could be completed. From the pooled data of the four studies, there were 1,041 participants (661 in the intervention group and 380 in the control group). The assessment of methodological quality raised issues associated with randomization and patient selection. Three themes were identified from the narrative synthesis: respiratory function, quality of life, and medication use. Conclusion Themes generated from the narrative synthesis data reflect outcome measures regularly used for interventional research associated with COPD. From this review, recommendations for inclusion of halotherapy as a therapy for COPD cannot be made at this point and there is a need for high quality studies to determine the effectiveness of this therapy.

The first and last halochamber are the ones recommended for cardio–respiratory, immuno–thyroid and osteo–muscular conditions, as well as in psycho–motor disorders. Based on questionnaires carried out over the course of a year, between 1 September 2021–31 August 2022, in two periods of stationing/treatment: a cold one (15 September 2021–15 December 2021) and a warm one (1 May 2022–30 July 2022), correlated with the data from the Salina medical office, achieved the profile of the improvement rate of the patients’ ailments depending on the type of treatment (working regime in halochambers). These studies have allowed the optimization of the treatment conditions in the artificial surface halochambers in order to reduce the stationary period and optimize the treatment cycles.

Objective Intrinsic atopic dermatitis (AD) is a chronic inflammatory skin disease with pruritus and eczematous lesions of skin. A long-lasting cycle of itch-scratch roots results in substantial morbidities and discomfort. Treatment of patients with moderate to severe dermatitis is a challenge. To evaluate the efficacy of a treatment based on mineral salts and natural antioxidants agents in patients with AD. Patients and Methods In this prospective study, 34 patients with AD were treated for 14 days. Patients were evaluated before and after treatment. The effects were studied by the following clinical measurements: Eczema Area and Severity Index (EASI), Scoring Atopic Dermatitis (SCORAD), Body Surface Area (BSA), and Validated Investigator Global Assessment for Atopic Dermatitis (vIGA-AD). Patient-reported measurements were also assessed: Patient-Oriented Eczema Measure (POEM), Dermatology Life Quality Index (DLQI), and the pruritus Numeric Rating Scale (NRS). Biopsies were performed in 10 patients and immunohistochemistry tests in 7 patients. Results All clinical and patient-reported measurements showed a strong difference before and after treatment. The epidermis thickness was significantly reduced, as well as the lymphocyte infiltration and the reduction of CD3, CD4, CD8, CD20 and CD117 cells. No adverse events were observed. Conclusion This study shows that the severity of intrinsic dermatitis was drastically reduced with the treatment of mineral salts and natural antioxidants agents. This topic treatment was very well tolerated without adverse events. Plain Language Summary Atopic dermatitis is very frequent disease of the skin. The symptoms are itching and eczematous skin lesions. Patients suffering from atopic dermatitis can develop systemic infections, cardiovascular diseases and to some neuropsychiatric conditions, including depression, anxiety and hyperactivity disorders. The most widely used treatment so far are glucocorticoids, which have significant side effects. Based on the effects of Dead Sea Water and magnesium salts, we designed a formula with natural ingredients. We combined mineral salts and antioxidants agents. In our study, we included 34 patients with atopic dermatitis who used our compound for 14 days. All patients showed significant improvement in their skin, as can be seen in the photographs of the 33 patients shown. We have also performed biopsies before and after treatment, showing an important improvement in the skin. In short, we have developed a natural product that has no side effects that moisturizes the skin, cures itching, and has antioxidant activity.

Sodium (Na + ) can accumulate in the skin tissue, sequestered by negatively charged glycosaminoglycans (GAGs). During dietary salt overload, the amount and charge density of dermal GAG molecules – e.g., hyaluronic acid (HA) and chondroitin sulfate (CS) – increases; however, the regulation of the process is unknown. Previously, it has been demonstrated that the level of cyclooxygenase-2 (COX-2) activity and the content of prostaglandin E2 (PGE2) are elevated in the skin due to high-salt consumption. A link between the COX-2/PGE2 system and GAG synthesis was also suggested. We hypothesized that in dermal fibroblasts (DFs) high-sodium concentration activates the COX-2/PGE2 pathway and also that PGE2 increases the production of HA. Our further aim was to demonstrate that the elevation of the GAG content is ceased by COX-2 inhibition in a salt overloaded animal model. For this, we investigated the messenger RNA (mRNA) expression of COX-2 and HA synthase 2 enzymes as well as the PGE2 and HA production of DFs by real-time reverse transcription PCR (qRT-PCR) and ELISA, respectively. The results showed that both high-sodium concentration and PGE2 treatment increases HA content of the media. Sodium excess activates the COX-2/PGE2 pathway in DFs, and COX-2 inhibition decreases the synthesis of HA. In the animal experiment, the HA- and CS disaccharide content in the skin of male Wistar rats was measured using high performance liquid chromatography-mass spectrometry (HPLC-MS). In the skin of rats receiving high-salt diet, the content of both HA‐ and monosulfated-CS disaccharides increased, whereas COX-2 inhibition blocked this overproduction. In conclusion, high-salt environment could induce GAG production of DFs in a COX-2/PGE2-dependent manner. Moreover, the COX-2 inhibition resulted in a decreased skin GAG content of the salt overloaded rats. These data revealed a new DF-mediated regulation of GAG synthesis in the skin during salt overload. sodium storage hypertonicity dermal fibroblast skin cyclooxygenase-2 prostaglandin E2 glycosaminoglycan hypertension János Bolyai Research Scholarship of the Hungarian Academy of Sciences &

ABSTRACT INTRODUCTION Asthma diagnosis can be confirmed through the observation of significant bronchodilator response (BDR) measured by peak expiratory flow (PEF) during home monitoring or by forced expiratory volume in one second (FEV 1 ) with spirometry in a clinical setting. AIM To use salbutamol administration after an exercise challenge test in children as a model of bronchodilation to assess how well relative change in PEF reflects improvement in lung function, as defined by increase in FEV 1 . METHODS We retrospectively studied 326 free running exercise challenge tests with spirometry in children 6–16 years old. To assess congruency and differences between relative changes in PEF and FEV 1 during bronchodilation, a regression analysis was performed, and a Bland – Altman plot was constructed. ROC analysis, sensitivity, specificity, positive and negative predictive values and Cohen’s kappa coefficient were used to analyze how accurately increases in PEF predict an increase of 12% & 0.2 L in FEV 1 . RESULTS Relative change in PEF was, on average, greater than that in FEV 1 . In ROC analysis, the area under the curve for PEF change was 0.837, with an optimal operating point of 14.5% (95% CI, 7.5–21.0%). The currently recommended cut-off for handheld PEF meters during home monitoring (15% increase) yielded a sensitivity of 71% and a specificity of 78%. The highest kappa value was observed at a 20% PEF cut-off. CONCLUSION Increase in PEF is not an accurate measure of BDR compared with increase in FEV 1 . The patient populations identified using PEF and FEV 1 criteria differ markedly.

Despite significant advances in CF therapy, there is still a critical need for alternative, individualized treatment options, especially for patients with untreatable CFTR mutations. Although intestinal organoids and primary airway cells are widely used as preclinical models of CF, both systems exhibit limitations with regard to the proper modelling of mucociliary clearance or the availability of sufficient cell quant

Background Psychological effects of air ions have been reported for more than 80 years in the media and scientific literature. This study summarizes a qualitative literature review and quantitative meta-analysis, where applicable, that examines the potential effects of exposure to negative and positive air ions on psychological measures of mood and emotional state. Methods A structured literature review was conducted to identify human experimental studies published through August, 2012. Thirty-three studies (1957–2012) evaluating the effects of air ionization on depression, anxiety, mood states, and subjective feelings of mental well-being in humans were included. Five studies on negative ionization and depression (measured using a structured interview guide) were evaluated by level of exposure intensity (high vs. low) using meta-analysis. Results Consistent ionization effects were not observed for anxiety, mood, relaxation/sleep, and personal comfort. In contrast, meta-analysis results showed that negative ionization, overall, was significantly associated with lower depression ratings, with a stronger association observed at high levels of negative ion exposure (mean summary effect and 95% confidence interval (CI) following high- and low-density exposure: 14.28 (95% CI: 12.93-15.62) and 7.23 (95% CI: 2.62-11.83), respectively). The response to high-density ionization was observed in patients with seasonal or chronic depression, but an effect of low-density ionization was observed only in patients with seasonal depression. However, no relationship between the duration or frequency of ionization treatment on depression ratings was evident. Conclusions No consistent influence of positive or negative air ionization on anxiety, mood, relaxation, sleep, and personal comfort measures was observed. Negative air ionization was associated with lower depression scores particularly at the highest exposure level. Future research is needed to evaluate the biological plausibility of this association.

While their evidence is inconsistent, the findings have increased awareness of mood alterations possibly associated with such exposure. Ions are ubiquitous, whereby any molecule with an unbalanced electron to proton ratio results in a net positive or negative electrical charge [ 1 ]. Air ions are produced from alterations in the atmosphere and weather phenomena, by natural radioactivity, and by combustion processes [ 2 , 3 ]. They are also generated by air ionizers sold commercially and by corona activity on the surface of high voltage conductors of transmission lines. Some experimental research indicates that exposure to negative air ions is linked to reduced depression severity [ 4 - 8 ], lower psychological stress [ 9 ], less anxiety [ 10 ], and enhanced well-being [ 11 - 14 ]. Others suggest that exposure to positive air ions may be associated with feelings of unpleasantness, irritability, and heightened anxiety [ 15 - 17 ]; while some have found no mood alterations associated

Juvenile primary fibromyalgia syndrome (JPFS) is a chronic musculoskeletal pain syndrome affecting children and adolescents. In part one of this review, we discussed the epidemiology, etiology, pathogenesis, clinical manifestations and diagnosis of JPFS. Part two focuses on the treatment and prognosis of JPFS. Early intervention is important. The standard of care is multidisciplinary, combining various modalities—most importantly, exercise and cognitive behavioral therapy. Prognosis varies and symptoms may persist into adulthood.

It can be caused by a variety of inflammatory or non-inflammatory conditions, including arthritis, hypermobility, fibromyalgia (FM), growing pains and complex regional pain syndrome (CRPS) Amplified musculoskeletal pain syndrome is a generic, descriptive term used to describe chronic pain syndromes of unconfirmed etiology, such as FM, CRPS and idiopathic musculoskeletal pain. For individuals with this syndrome, pain signals are augmented; thus, mildly painful and nonpainful stimuli are registered by the body as very painful, which leads to attempts to avoid the induction of pain, leading to functional disability. Our previous review focused on CRPS [ 2 ]. Yunus and Masi were the first to describe and use the term juvenile primary fibromyalgia syndrome (JPFS), in a clinical study published in 1985, in which they suggested diagnostic criteria based on 33 juveniles ages 17 years or younger, who suffered from chronic pain. JPFS is defined by chronic diffuse musculoskeletal aching and pain, which is the hallmark of this condition, and multiple predictable tender points. Part one of this review summarized the current information regarding the epidemiology, etiology, clinical manifestations and diagnosis of JPFS [ 3 ]. This part of the review focuses on treatment and prognosis. Treatment The primary goal in the treatment of JPFS is to enhance quality of life through pain relief and improved function. A multidisciplinary approach, combining behavioral and exercise-based modalities is currently the standard of care for JPFS [ 4 , 5 ]. Treatment should begin with non-pharmacologic modalities, most importantly exercise. Other non-pharmacologic modalities include movement and meditative treatments, and Cognitive Behavioral Therapy (CBT) [ 6 ]. Reassurance is very important, including acknowledging that the patient’s pain is real, and emphasizing that it is not dangerous. Caregivers should communicate that although the pain may last for an unknown period

Background and Objectives The aim of this study was to perform a systematic review and meta-analysis evaluating the efficacy of topical manuka honey in the postoperative management of chronic rhinosinusitis following endoscopic sinus surgery. Methods A systematic search was conducted using PubMed, Embase, OVID, Google Scholar, Web of Science, and the Cochrane Central Register of Controlled Trials. Data were extracted from the randomized trials identified for meta-analysis. Outcome measures—including visual analogue scales, quality of life assessed by the Sinonasal Outcome Test-22, the Philpott-Javer endoscopic score or Lund-Kennedy endoscopic score, post-treatment culture negativity, and adverse effects—were compared between the manuka honey treatment and control groups. Heterogeneity was assessed within subgroups. Results Four studies including 134 patients were incorporated into the meta-analysis. All subgroup analyses exhibited low heterogeneity. Visual analogue scale scores showed no significant differences, indicating that manuka honey did not cause definite discomfort (standardized mean difference [SMD], -0.46; 95% confidence interval [CI], -1.02 to 0.10). Similarly, improvement in the Sinonasal Outcome Test-22 score was not statistically significant (SMD, -0.03; 95% CI, -0.58 to 0.52). Although the Philpott-Javer score was slightly better in the manuka honey group, the difference was not statistically significant (SMD, 0.13; 95% CI, -0.26 to 0.52), and changes in the Lund-Kennedy endoscopic score from baseline were comparable (SMD, 0.59; 95% CI, -0.03 to 1.21). Culture negativity following manuka honey treatment was marginally improved compared to saline, yet without statistical significance (risk ratio, 0.43; 95% CI, 0.16 to 1.15). No serious adverse effects were reported in any study. Conclusion Although topical manuka honey appears to have no serious adverse effects, its efficacy should be reconsidered given the lack of statistically significant improvement in sinus mucosal status and post-treatment culture negativity. Further well-designed trials are warranted to clarify its potential benefits.

Persistent CRS can significantly decrease quality of life. CRS frequently necessitates endoscopic sinus surgery (ESS), making postoperative care crucial [ 1 ]. Poor treatment of recalcitrant CRS is often associated with bacterial biofilms, and the use of inappropriate antibiotics may exacerbate sympto

Halotherapy (HT), derived from speleotherapy in salt mines, is also a drug-free therapeutic method. HT effects vary depending on the therapeutic method and the structure of halotherapy environment. The purpose of this article is to show the HT effects of “halotherapy chamber with artificial salt-mine environment” of the National Institute of Rehabilitation, Physical Medicine and Balneoclimatology (INRMFB), on patients with bronchial asthma and other chronic, infectious-inflammatory and allergic respiratory diseases, describing the clinical effects on certain nonspecific resistance factors, on markers of inflammatory processes and on certain immunological changes. Patients were clinically assessed, with the application of hematologic investigations, analysis of nonspecific resistance to infection and of inflammatory process markers, immunologic assessments, analysis of sodium and potassium concentrations, of mineralocorticoid function and other biochemical tests. For the experimental HT therapy performed in the “halotherapy chamber with artificial salt-mine environment” of INRMFB, 15 patients suffering from bronchial asthma, allergic rhinitis, chronic bronchitis, chronic obstructive bronchopneumopathy were selected, based on specific medical indications and contraindications and applying ethical principles, as well as 4 patients with similar pathologies for the control group, who underwent in-home drug treatment. After the specific halotherapy treatment on patients with bronchial asthma, chronic bronchitis and chronic obstructive bronchopneumopathy, which also showed other chronic, infectious-inflammatory and allergic respiratory pathologies, triggering of anti-inflammatory (and also anti allergic) mechanisms and healing effects on inflammatory process were noted. Data acquired also proved the halo therapeutic effect causing the reduction of sensitiveness of body in patients with bronchial asthma.

Following the “survey for the innovative use of potentially therapeutic salt-mine environment factors, in health and balneoclimateric tourism; modeling solutions”, the conceptual model was elaborated, subsequently converted into an experimental functional model entitled “halotherapy chamber with artificial salt-mine environment”, destined for surface halotherapy and built within the National Institute of Rehabilitation, Physical Medicine and Balneoclimatology. This model was followed by surveys in the underground salt-mine environment, destined to assess the presence and quality of factors with speleotherapeutic / halotherapeutic potential, medical-biological multi-discipline surveys, including organismic and cellular-level analysis, before and after the experimental halotherapy treatment, on lab animals – Wistar rats with pathology experimentally induced by sensitization with ovalbumin. Based on the experimental results acquired [ 1 , 2 ], the “Inception medical indications for
