Review
Available treatments of depression have limited efficacy and unsatisfactory remission rates. This study aims to review randomized controlled trials (RCTs) investigating effects of glutamate receptor modulators in treating patients with resistant depression. The study protocol was registered in PROSPERO (CRD42021225516). Scopus, ISI Web of Science, Embase, Cochrane Library, Google Scholar, and three trial registries were searched up to September 2020 to find RCTs evaluating glutamate receptor modulators for resistant depression. The difference between intervention and control groups in changing depression scores from baseline to endpoint was considered the primary outcome. Version 2 of the Cochrane risk-of-bias tool for randomized trials was used to assess the quality of the RCTs. No funding was received. Thirty-eight RCTs were included. Based on the included studies, compelling evidence was found for ketamine (with or without electroconvulsive therapy, intravenous or other forms), nitrous oxide, amantadine, and rislenemdaz (MK-0657); the results for MK-0657, amantadine, and nitrous oxide were only based on one study for each. Lithium, lanicemine, D-cycloserine, and decoglurant showed mixed results for efficacy, and, riluzole, and 7-chlorokynurenic acid were mostly comparable to placebo. A limited number of studies were available that addressed drugs other than ketamine. The study cannot determine the difference between statistical and clinical significance between the agents and placebo due to high heterogeneity among the RCTs. Nevertheless, ketamine could be used as an efficacious drug in TRD; still, additional studies are needed to delineate the optimum dosage, duration of efficacy, and intervals. Further studies are also recommended on the effectiveness of glutamatergic system modulators other than ketamine on treatment-resistant depression.

Review
This systematic review investigates the emissions from ultrasonic humidifiers (e.g., cool mist humidifiers) within indoor air environments, namely soluble and insoluble metals and minerals as well as microorganisms and one organic chemical biocide. Relationships between ultrasonic humidifier fill water quality and the emissions in indoor air are studied, and associated potential adverse health outcomes are discussed. Literature from January 1, 1980, to February 1, 2022, was searched from online databases of PubMed, Web of Science, and Scopus to produce 27 articles. The results revealed clear positive proportional relationships of the concentration of microorganisms and soluble metals/minerals between fill water qualities and emitted airborne particles, for both microbial (n = 9) and inorganic (n = 15) constituents. When evaluating emissions and the consequent health outcomes, ventilation rates of specific exposure scenarios affect the concentrations of emitted particles. Thus, well-ventilated rooms may alleviate inhalation risks when the fill water in ultrasonic humidifiers contains microorganisms and soluble metals/minerals. Case reports (n = 3) possibly due to the inhalation of particles from ultrasonic humidifier include hypersensitivity pneumonitis in adults and a 6-month infant; the young infant exhibited nonreversible mild obstructive ventilator defect. In summary, related literature indicated correlation between fill water quality of ultrasonic humidifier and emitted particles in air quality, and inhalation of the emitted particles may cause undesirable health outcomes of impaired respiratory functions in adults and children.

Meta-Analysis
INTRODUCTION
This study was performed to compare probabilities of SDI on the Expanded Disability Status Scale (EDSS) in patients with relapsing-remitting multiple sclerosis (RRMS), treated with cladribine tablets (CT) or fingolimod (FTY), natalizumab (NAT), alemtuzumab (ALE) and ocrelizumab (OCR).
CLINICAL RATIONALE FOR THE STUDY
Progression of neurological disability as measured by the EDSS has been a common endpoint in multiple sclerosis (MS) trials. Novel therapies can not only slow this process, but in some patients even reverse it. This effect can be measured by the sustained disability improvement (SDI) - an endpoint that seems to continuously gain importance in clinical practice. Despite that, SDI has rarely been explored as an outcome in MS clinical studies, mostly as post-hoc analyses from randomised trials or as retrospective analyses based on patient registry records.
MATERIAL AND METHODS
A systematic review was conducted in Medline, Embase and Cochrane to identify clinical trials (RCT or non-RCT) evaluating 6-month SDI. An indirect comparison via network meta-analysis (NMA) was performed. Bayesian inference with Markov chains Monte Carlo methods were applied.
RESULTS
Eight trials presenting SDI results and applicable for NMA were included: six non-RCTs, with control groups selected by propensity score matching, and two RCTs. NMA results revealed that probability of achieving 6-month SDI with CT was significantly higher compared to all other high efficacy disease-modifying drugs with available data - HR (95% Crl - Bayesian Credibility Interval) vs. FTY: 4.98 (2.11-11.79); vs. NAT: 3.12 (1.31-7.27); vs. ALE: 9.29 (3.40-25.21). The main results were confirmed in the sensitivity analyses.
CONCLUSIONS
Of all considered therapies, treatment with cladribine tablets was associated with a higher probability of sustained disability improvement in RRMS patients. As this conclusion is based on available clinical data of limited quality, future studies, as well as real-world data, would be valuable to provide further evidence regarding the comparative effectiveness of RRMS therapies.

Medicine Nov 2022Meta-analysis was used to evaluate the efficacy of Fufang Biejia Ruangan Tablets in the treatment of chronic hepatitis B (CHB) liver fibrosis. (Meta-Analysis)
Meta-Analysis
BACKGROUND
Meta-analysis was used to evaluate the efficacy of Fufang Biejia Ruangan Tablets in the treatment of chronic hepatitis B (CHB) liver fibrosis.
METHODS
Databases, including PubMed, China Knowledge Network (CNKI), China Biomedical Database (CBM), Wan Fang, VIP database, Embase, and Cochrane Library were searched. The time was searched up to May 2022. The participant intervention comparator outcomes of this study were as follows: P, patients with CHB liver fibrosis; I, Fufang Biejia Ruangan Tablets; C, pharmacological placebo; O, the efficacy rate, alanine transaminase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL), albumin (ALB), procollagen III protein (PIIIP), hyaluronic acid (HA), laminin (LN), collagen C type IV (IV-C), portal vein diameter, spleen thickness and HBV-DNA negative conversion rate. The Cochrane Risk of Bias tool, Begg's test and Egger's test were used to evaluate the methodological quality of eligible studies. A randomized controlled trial of Fufang Biejia Ruangan Tablets was used to treat CHB liver fibrosis. Three reviewers independently selected trials, extracted data, cross-checked, and performed methodological quality assessments. Data analysis was completed by Review Manager 5.3.
RESULTS
Twenty-six studies with 2717 patients were included in the meta-analysis. The meta-analysis showed that Fufang Biejia Ruangan Tablets was effective by increasing the efficacy. Fufang Biejia Ruangan Tablets was more efficient in improving ALT, AST, TBIL, ALB, PIIIP, HA, LN, IV-C, portal vein diameter, spleen thickness, and HBV-DNA negative conversion rate with no serious adverse reactions.
CONCLUSION
It was shown that Fufang Biejia Ruangan Tablets can effectively improve liver function and relieve liver fibrosis, but future research should focus on rigorously designed, multicenter, and large randomized controlled trials.

OBJECTIVE
to synthesize the evidence available in the literature on the effects of integrative and complementary practices in nausea and vomiting treatment in pregnant women.
METHOD
a systematic review, reported according to PRISMA and registered in PROSPERO. The search for studies was carried out in 11 databases. To assess risk of bias in randomized clinical trials, the Cochrane Collaboration Risk of Bias Tool (RoB 2) was used.
RESULTS
the final sample consisted of 31 articles, divided into three categories: aromatherapy, phytotherapy and acupuncture. It was observed that aromatherapy with lemon essential oil, ginger capsules, pericardial 6 point acupressure were the interventions that proved to be effective. Less than half of studies reported adverse effects, with mild and transient symptoms predominating. Most articles were classified as "some concern" in risk of bias assessment.
CONCLUSION
the three most effective interventions to control gestational nausea and vomiting were aromatherapy, herbal medicine and acupuncture, with significant results in the assessment of individual studies.

Meta-Analysis
BACKGROUND
Rapid fluid administration may decrease hemoglobin concentration (Hb) by a diluting effect, which could limit the increase in oxygen delivery (DO) expected with a positive response to fluid challenge in critically ill patients. Our aim was to quantify the decrease in Hb after rapid fluid administration.
METHODS
Our protocol was registered in PROSPERO (CRD42020165146). We searched PubMed, the Cochrane Database, and Embase from inception until February 15, 2022. We selected studies that reported Hb before and after rapid fluid administration (bolus fluid given over less than 120 min) with crystalloids and/or colloids in adults. Exclusion criteria were studies that included bleeding patients, or used transfusions or extracorporeal circulation procedures. Studies were divided according to whether they involved non-acutely ill or acutely ill (surgical/trauma, sepsis, circulatory shock or severe hypovolemia, and mixed conditions) subjects. The mean Hb difference and, where reported, the DO difference before and after fluid administration were extracted. Meta-analyses were conducted to assess differences in Hb before and after rapid fluid administration in all subjects and across subgroups. Random-effect models, meta-regressions and subgroup analyses were performed for meta-analyses. Risk of bias was assessed using the Cochrane Risk of Bias Assessment Tool. Inconsistency among trial results was assessed using the I statistic.
RESULTS
Sixty-five studies met our inclusion criteria (40 in non-acutely ill and 25 in acutely ill subjects), with a total of 2794 participants. Risk of bias was assessed as "low" for randomized controlled trials (RCTs) and 'low to moderate' for non-RCTs. Across 63 studies suitable for meta-analysis, the Hb decreased significantly by a mean of 1.33 g/dL [95% CI - 1.45 to - 1.12; p < 0.001; I = 96.88] after fluid administration: in non-acutely ill subjects, the mean decrease was 1.56 g/dL [95% CI - 1.69 to - 1.42; p < 0.001; I = 96.71] and in acutely ill patients 0.84 g/dL [95% CI - 1.03 to - 0.64; p = 0.033; I = 92.91]. The decrease in Hb was less marked in patients with sepsis than in other acutely ill patients. The DO decreased significantly in fluid non-responders with a significant decrease in Hb.
CONCLUSIONS
Hb decreased consistently after rapid fluid administration with moderate certainty of evidence. This effect may limit the positive effects of fluid challenges on DO and thus on tissue oxygenation.

BACKGROUND
Anthrax is a toxin-mediated zoonotic disease caused by Bacillus anthracis, with a worldwide distribution recognized for millennia. Bacillus anthracis is considered a potential biowarfare agent.
METHODS
We completed a systematic review for clinical and demographic characteristics of adults and children hospitalized with anthrax (cutaneous, inhalation, ingestion, injection [from contaminated heroin], primary meningitis) abstracted from published case reports, case series, and line lists in English from 1880 through 2018, assessing treatment impact by type and severity of disease. We analyzed geographic distribution, route of infection, exposure to anthrax, and incubation period.
RESULTS
Data on 764 adults and 167 children were reviewed. Most cases reported for 1880 through 1915 were from Europe; those for 1916 through 1950 were from North America; and from 1951 on, cases were from Asia. Cutaneous was the most common form of anthrax for all populations. Since 1960, adult anthrax mortality has ranged from 31% for cutaneous to 90% for primary meningitis. Median incubation periods ranged from 1 day (interquartile range [IQR], 0-4) for injection to 7 days (IQR, 4-9) for inhalation anthrax. Most patients with inhalation anthrax developed pleural effusions and more than half with ingestion anthrax developed ascites. Treatment and critical care advances have improved survival for those with systemic symptoms, from approximately 30% in those untreated to approximately 70% in those receiving antimicrobials or antiserum/antitoxin.
CONCLUSIONS
This review provides an improved evidence base for both clinical care of individual anthrax patients and public health planning for wide-area aerosol releases of B. anthracis spores.

This meta-analysis aimed to assess the effectiveness and safety of Chinese herbal medicine (CHM) in treating chronic fatigue syndrome (CFS). Nine electronic databases were searched from inception to May 2022. Two reviewers screened studies, extracted the data, and assessed the risk of bias independently. The meta-analysis was performed using the Stata 12.0 software. Eighty-four RCTs that explored the efficacy of 69 kinds of Chinese herbal formulas with various dosage forms (decoction, granule, oral liquid, pill, ointment, capsule, and herbal porridge), involving 6,944 participants were identified. This meta-analysis showed that the application of CHM for CFS can decrease Fatigue Scale scores (WMD: -1.77; 95%CI: -1.96 to -1.57; < 0.001), Fatigue Assessment Instrument scores (WMD: -15.75; 95%CI: -26.89 to -4.61; 0.01), Self-Rating Scale of mental state scores (WMD: -9.72; 95%CI:-12.26 to -7.18; 0.001), Self-Rating Anxiety Scale scores (WMD: -7.07; 95%CI: -9.96 to -4.19; < 0.001), Self-Rating Depression Scale scores (WMD: -5.45; 95%CI: -6.82 to -4.08; < 0.001), and clinical symptom scores (WMD: -5.37; 95%CI: -6.13 to -4.60; < 0.001) and improve IGA (WMD: 0.30; 95%CI: 0.20-0.41; 0.001), IGG (WMD: 1.74; 95%CI: 0.87-2.62; 0.001), IGM (WMD: 0.21; 95%CI: 0.14-0.29; 0.001), and the effective rate (RR = 1.41; 95%CI: 1.33-1.49; 0.001). However, natural killer cell levels did not change significantly. The included studies did not report any serious adverse events. In addition, the methodology quality of the included RCTs was generally not high. Our study showed that CHM seems to be effective and safe in the treatment of CFS. However, given the poor quality of reports from these studies, the results should be interpreted cautiously. More international multi-centered, double-blinded, well-designed, randomized controlled trials are needed in future research. : [https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42022319680], identifier [CRD42022319680].

Review
The bioactive chemicals in cigarette smoke (CS) and e-cigarette vapor (EV) may affect pathogenic bacteria in the nasopharyngeal microflora, which may have implications on the pathophysiology of respiratory infections in cigarette smokers and e-cigarette users. In this systematic review, we seek to synthesize the research evidence supporting this hypothesis. To address the central research question, "", we screened the PubMed, Web of Science, and ScienceDirect databases for reports examining the virulence characteristics and gene expression in human pathogenic bacteria exposed to either CS or EV. The principal conclusion from our analysis is that exposure to either CS or EV induces the virulence of respiratory pathogenic bacteria in a strain-dependent manner, which may in turn facilitate respiratory infections in cigarette smokers and e-cigarette users. In addition, we present evidence that nicotine and reactive oxygen species are the main chemicals responsible for CS/EV-mediated alterations in bacterial physiology. We note limitations that this review does not examine reports describing the alterations in host respiratory physiology or nasopharyngeal dysbiosis caused by CS/EV exposure. Future research to determine whether CS/EV-mediated augmentation of bacterial virulence indeed plays a role in human respiratory tract infections is warranted.

Meta-Analysis Review
Severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) is a global and evolving pandemic associated with heavy health and financial burdens. Considering the oral cavity as the major reservoir for SARS-CoV-2, a systematic review and meta-analysis were conducted to assess the efficacy of mouth rinses and nasal sprays in reducing the salivary viral load of SARS-CoV-2. All and studies that assessed the virucidal efficacy of mouth rinses and nasal sprays against SARS-CoV-2 and were published in the English language from December 2019 to April 2022 were considered for analyses. Special Medical Subject Headings terms were used to search Pubmed, Scopus, Embase Ovid, and Web of Science databases. The toxicological data reliability assessment tool (ToxRToool) was used to assess the quality of the included studies. Thirty-three studies (11 and 22 ) were deemed eligible for inclusion in this analysis. Results of the pooled data showed that povidone-iodine is the most efficacious intervention in terms of reducing the SARS-CoV-2 salivary viral load, followed by chlorhexidine. The mean difference in the viral load was 86% and 72%, respectively. Similarly, povidone-iodine was associated with the highest log reduction value (LRV) , followed by cetylpyridinium chloride, (LRV = 2.938 ( < 0.0005) and LRV = 2.907 ( = 0.009), respectively). Povidone-iodine-based oral and nasal preparations showed favourable results in terms of reducing SARS-CoV-2 viral loads both and . Considering the limited number of patients , further studies among larger cohorts are recommended.
