Abstract Introduction Fennel has many medicinal properties and is used in the treatment of dysmenorrhea. Given the widespread use of herbal medicine among women for menstrual problems and considering the fact that there has been no study to date about the effect of fennel on menstrual bleeding and duration of menstrual bleeding through systematic review, the present study was conducted to determine the effect of fennel on the amount (primary outcome) and duration of menstrual bleeding and its side-effects (secondary outcomes). Materials All articles, including Persian and English, with no time limit were searched for in the following databases: Medline (through PubMed), Scopus, EMBASE (through Ovid), Cochrane Library, Web of Sciences, Google Scholar, ProQuest, Clininaltrial.gov, SID, Magiran, Irandoc, and Iranmedex, using MeSH terms, including menstrual bleeding, menstruation, severity of bleeding, hypermenorrhea, menorrhagia, fennel, fennelin, Foeniculum vulgare, dysmenorrhea, and painful menstruation, which were searched separately or in combination. Two authors separately reviewed articles to determine the inclusion criteria, and any disagreement was resolved by reaching consensus with a third person. Results A total of 7993 articles were identified through searching the databases, of which 7327 were excluded as duplicates and 666 were screened for inclusion. Six hundread and forty six were excluded by title and abstract based on not being relevant to the review and being conducted on animals. Eventually, six articles were included in the study and four articles entered into the meta-analysis. The results from meta-analysis showed that using fennel caused a significant increase in mean menstrual bleeding in the first cycle after treatment in the intervention group compared to the control (Std. mean difference: 0.46; 95 % CI: 0.18–0.73; p = 0.001; I2 = 9 %). However, it had no significant effect on menstrual bleeding in the second cycle after treatment (Mean difference: 1.44; 95 % CI:-5.09 to 7.96; p = 0.67; I2 = 0 %). Conclusions The results of meta-analysis of four articles showed that in the first cycle after treatment, use of fennel increased menstrual bleeding in the intervention group compared to the control, but meta-analysis of two articles showed no significant difference between intervention and control groups in the amount of menstrual bleeding in the second cycle after treatment. Given the poor quality of articles, conducting clinical trials to determine the effect of fennel on menstrual bleeding appears necessary.

Objective: In this meta-analysis and systematic review, we aimed to evaluate the effects of the TISADs to facilitates anchorage reinforcement. Methods:  PubMed, Cochrane Library, Embase, ISI, Scopus, Web of Science, LILACS, BBO, OpenGrey, and Google Scholar, were used from the electronic databases until 2020 perform systematic literature. Two reviewers extracted data blindly and independently from various abstracts as well as full texts of articles they considered for data extraction. Using the Cochrane collaboration's tool, we evaluated the publications' quality. Then, we computed the mean difference of TISADs and conventional anchorage groups with a confidence interval (CI) of 95%, restricted maximum likelihood (REML), and random effect model of the mesial movement of molars and their tipping. Moreover, we employed Stata/MP 16 that has been considered the most rapid version of Stata for evaluating meta-analysis. Results: According to our electronic searches, 134 topics and abstracts with potential relevance were identified according to the research design. Finally, five publications matched the required inclusion criteria of the study. In addition, the Cochrane collaboration instrument exhibited all studies with low to moderate biases. Also, the mean difference of mesial molar movement showed less anchorage loss in the TISADs group vs. the controls, and a significant difference between these two groups (MD= -1.74 with a CI of 95%, -2.76, -0.71. P = 0.00). Conclusions: TISADs can reduce treatment time, and TISADs are more effective in enables the anchorage than other methods and higher tipping in the TISADs.

Objective: A systematic review and meta-analysis was carried out to examine the role of hydroxychloroquine (HCQ) in the treatment of COVID-19. Methods: We performed a systematic search in PubMed, Scopus, Embase, Cochrane- Library, Web of Science, Google Scholar, and medRxiv pre-print databases using available MeSH terms for COVID-19 and hydroxychloroquine. Data from all studies that focused on the effectiveness of HCQ with or without the addition of azithromycin (AZM) in confirmed COVID-19 patients, which were published up to 12 September 2020, were collated for analysis using CMA v.2.2.064. Results: Our systematic review retrieved 41 studies. Among these, 37 studies including 45,913 participants fulfilled the criteria for subsequent meta-analysis. The data showed no significant difference in treatment efficacy between the HCQ and control groups (RR: 1.02, 95% CI, 0.81–1.27). Combination of HCQ with AZM also did not lead to improved treatment outcomes (RR: 1.26, 95% CI, 0.91–1.74). Furthermore, the mortality difference was not significant, neither in HCQ treatment group (RR: 0.86, 95% CI, 0.71–1.03) nor in HCQ plus AZM treatment group (RR: 1.28, 95% CI, 0.76–2.14) in comparison to controls. Meta-regression analysis showed that age was the factor that significantly affected mortality (P<0.00001). Conclusion: The meta-analysis found that there was no clinical benefit of using either HCQ by itself or in combination with AZM for the treatment of COVID-19 patients. Hence, it may be prudent for clinicians and researchers to focus on other therapeutic options that may show greater promise in this disease. Keywords: Azithromycin, coronavirus outbreaks, pandemic, SARS-CoV-2 disease

Objective To determine the impact of treatment for patients with nasal obstruction secondary to allergic rhinitis (AR) and nasal septal deviation (NSD) on sleep quality. Data Sources Primary studies were identified though PubMed, Scopus, Cochrane Library, and Web of Science. Review Methods A systematic review was performed by querying databases for articles published through August 2020. Studies were included that reported on objective sleep parameters (apnea-hypopnea index) and sinonasal and sleep-specific patient-reported outcome measures: Rhinoconjunctivitis Quality of Life Questionnaire, Nasal Obstruction Symptom Evaluation, Epworth Sleepiness Scale (EpSS), and Pittsburgh Sleep Quality Index (PSQI). Results The database search yielded 1414 unique articles, of which 28 AR and 7 NSD studies were utilized for meta-analysis. A total of 9037 patients (8515 with AR, 522 with NSD) were identified with a mean age of 35.0 years (35.3 for AR, 34.0 for NSD). Treatment for AR and NSD significantly improved subjective sleep quality. For AR, the EpSS mean difference was −1.5 (95% CI, –2.4 to –0.5; P = .002) and for the PSQI, –1.7 (95% CI, –2.1 to –1.2; P < .00001). For NSD, the EpSS mean difference was −3.2 (95% CI, –4.2 to –2.2; P < .00001) and for the PSQI, –3.4 (95% CI, –6.1 to –0.6; P = .02). Conclusion Subjective sleep quality significantly improved following treatment for AR and NSD. There were insufficient data to demonstrate that objective metrics of sleep quality similarly improved.

Abstract Objective We conducted a systematic review and meta-analysis to determine the effectiveness of comprehensive community-based interventions with ≥ 2 components in improving asthma outcomes in children. Methods A systematic search of Medline, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Excerpta Medica Database (EMBASE), Cochrane Library and hand search of reference collections were conducted to identify any research articles published in English between 2000 and 2019. All studies reporting community-based asthma interventions with ≥ 2 components (e.g., asthma self-management education, home environmental assessment or care coordination etc.) for children aged ≤ 18 years were included. Meta-analyses were performed using random-effects model to estimate pooled odds ratio (OR) with 95% confidence intervals (CIs). Results Of the 2352 studies identified, 21 studies were included in the final analysis: 19 pre-post interventions, one randomised controlled trial (RCT) and one retrospective study. Comprehensive asthma programs with multicomponent interventions were associated with significant reduction in asthma-related Emergency Department (ED) visits (OR = 0.26; 95% CI 0.20–0.35), hospitalizations (OR = 0.24; 95% CI 0.15–0.38), number of days (mean difference = − 2.58; 95% CI − 3.00 to − 2.17) and nights with asthma symptoms (mean difference = − 2.14; 95% CI − 2.94 to − 1.34), use of short-acting asthma medications/bronchodilators (BD) (OR = 0.28; 95% CI 0.16–0.51), and increase use of asthma action plan (AAP) (OR = 8.87; 95% CI 3.85–20.45). Conclusion Community-based asthma care using more comprehensive approaches may improve childhood asthma management and reduce asthma related health care utilization.

Reducing unnecessary routine diagnostic testing has been identified as a strategy to curb wasteful healthcare. However, the safety and efficacy of targeted diagnostic testing strategies are uncertain. The aim of this study was to systematically review interventions designed to reduce pathology and chest radiograph testing in patients admitted to the intensive care unit (ICU). A predetermined protocol and search strategy included OVID MEDLINE, OVID EMBASE and the Cochrane Central Register of Controlled Trials from inception until 20 November 2019. Eligible publications included interventional studies of patients admitted to an ICU. There were no language restrictions. The primary outcomes were in-hospital mortality and test reduction. Key secondary outcomes included ICU mortality, length of stay, costs and adverse events. This systematic review analysed 26 studies (with more than 44,00 patients) reporting an intervention to reduce one or more diagnostic tests. No studies were at low risk of bias. In-hospital mortality, reported in seven studies, was not significantly different in the post-implementation group (829 of 9815 patients, 8.4%) compared with the pre-intervention group (1007 of 9848 patients, 10.2%), (relative risk 0.89, 95% confidence intervals 0.79 to 1.01, P = 0.06, I2 39%). Of the 18 studies reporting a difference in testing rates, all reported a decrease associated with targeted testing (range 6%–72%), with 14 (82%) studies reporting >20% reduction in one or more tests. Studies of ICU targeted test interventions are generally of low quality. The majority report substantial decreases in testing without evidence of a significant difference in hospital mortality.

Abstract Background Tuberculosis is a major public health problem caused by Mycobacterium tuberculosis, occurring predominantly in population with low socioeconomic status. It is the second most common cause of death from infectious diseases. Tuberculosis becomes a double burden among anemic patients. Anemia increases an individual’s susceptibility to infectious diseases including tuberculosis by reducing the immunity level. Therefore, the purpose of this study was to determine whether anemia is a risk factor for tuberculosis. Method Relevant published articles were searched in electronic databases like PubMed, Google Scholar, EMBASE, and Cochrane Library using the following MeSH terms: risk factor, predictors, tuberculosis, TB, Anaemia, Anemia, hemoglobin, Hgb, and Hb. Articles written in the English, observational studies conducted on the incidence/prevalence of tuberculosis among anemic patients, or papers examined anemia as risk factors for tuberculosis were included. From those studies meeting eligibility criteria, the first author’s name, publication year, study area, sample size and age of participants, study design, and effect measure of anemia for tuberculosis were extracted. The data were entered using Microsoft Excel and exported to Stata version 11 for analysis. The random-effects model was applied to estimate the pooled OR and HR, and 95% CI. The sources of heterogeneity were tested by Cochrane I-squared statistics. The publication bias was assessed using Egger’s test statistics. Results A total of 17 articles with a 215,294 study participants were included in the analysis. The odd of tuberculosis among anemic patients was 3.56 (95% CI 2.53–5.01) times higher than non-anemic patients. The cohort studies showed that the HR of tuberculosis was 2.01 (95% CI 1.70–2.37) times higher among anemic patients than non-anemic patients. The hazard of tuberculosis also increased with anemia severity (HR 1.37 (95% CI 0.92–2.05), 2.08 (95% CI 1.14–3.79), and 2.66 (95% CI 1.71–4.13) for mild, moderate, and severe anemia, respectively). Conclusion According to the current systematic review and meta-analysis, we can conclude that anemia was a risk factor for tuberculosis. Therefore, anemia screening, early diagnose, and treatment should be provoked in the community to reduce the burden of tuberculosis.

Objective. With the increasing social and economic burdens of balance impairment after stroke, the treatment for balance impairment after stroke becomes a major public health problem worldwide. Kinesio taping (KT) as a part of clinical practice has been used widely in the treatment of balance impairment after stroke. However, the clinical effects of KT for balance function have not been confirmed. The objective of this study is to investigate the effects and safety of KT for balance impairment after stroke. Methods. We conducted a systematic review (SR) and meta-analysis of randomized controlled trials (RCTs) on the effects of KT for balance impairment after stroke. We searched the following databases: (1) English databases: EMBASE (via Ovid), MEDLINE (via Ovid), the Cochrane library, PubMed, and PEDro; (2) Chinese databases: China Biology Medicine (CBM), Wan Fang database, China National Knowledge Infrastructure (CNKI), and VIP. Besides, hand searches of relevant references were also conducted. We systematically searched from the inception to December 2018, using the keywords (Kinesio, Kinesio Tape, tape, or Orthotic Tape) and (stroke, hemiplegia, or hemiplegic paralysis) and (balance or stability). The search strategies were adjusted for each database. The reference lists of included articles were reviewed for relevant trials. For missing data, we contacted the authors to get additional information. Results. 22 RCTs involved 1331 patients, among which 667 patients in the experimental group and 664 patients in the control group were included. Results of meta-analysis showed that, compared with conventional rehabilitation (CR), there was significant difference in Berg Balance Scale (BBS) (MD=4.46, 95%CI 1.72 to 7.19, P=0.001), Time Up and Go Test (TUGT) (MD=-4.62, 95%CI -5.48 to -3.79, P < 0.00001), functional ambulation category scale (FAC) (MD=0.53, 95%CI 0.38 to 0.68, P < 0.00001), Fugl-Meyer assessment (FMA-L) (MD=4.20, 95%CI 3.17 to 5.24, P < 0.00001), and Modified Ashworth Scale (MAS) (MD=-0.38, 95%CI -0.49 to -0.27, P < 0.00001). The results of subgroup analysis showed that there was no significant difference between KT and CR with ≤4 weeks treatment duration (< 4 weeks: MD=5.03, 95%CI -1.80 to 11.85, P=0.15; =4 weeks: MD=4.33, 95%CI -1.50 to 10.15, P=0.15), while there was significant difference with more than 4-week treatment duration (MD=4.77, 95%CI 2.58 to 6.97, P < 0.0001). Conclusions. Based on current evidence, KT was more effective than CR for balance function, lower limb function, and walking function in poststroke patients. Longer treatment duration may be associated with better effects. However, more well-conducted RCTs are required in the future.

Abstract  Background: Our study aims to evaluate, through a systematic review, the reliability of numerical models compared to conventional models on the main parameters of orthodontic diagnosis  Method: four databases were consulted: PubMed; Google Scholar, Cochrane Library, and Ebscohost. The research included published studies since 2010, meta-analysis studies, randomized and non-randomized controlled trials, prospective and retrospective studies. Results: Among 3811 selected references, only five studies met our inclusion criteria. In the systematic review, there were statistical differences between the digital models and the plaster models. However, this difference is clinically acceptable. On the other hand, there are some limitations, relative to the types of the severity of the congestion, the elapsed time to digitize, and the numerical means. Conclusion: The results of our systematic review have shown that there is no clinically significant difference between the numerical and physical models for the majority of diagnostic parameters.

Objectives: The present systematic review focused on the prevention or treatment of three main types of pelvic floor dysfunctions (PFDs) specifically pelvic organ prolapse (POP), urinary incontinence (UI), and fecal incontinence (FI) using physiotherapy and pelvic floor muscle exercises (PFMEs). With regard to the breadth of the problem, there is not much evidence grounded on the best management. The main purpose of this systematic review was to evaluate the effects of physiotherapy and PFMEs on the prevention and treatment of pregnancy-related PFDs; namely, POP, FI, and UI. Therefore, this review incorporated studies comparing the use of physiotherapy and PFMEs with every other existing interventions. Methods: This systematic review and meta-analysis was conducted on randomized-controlled-trial (RCT) articles and quasi-RCT designs through a search in the studies published with no time limits until December 2017 in the databases of PubMed (Medline), Web of Science, Scopus, Embase, Cochrane Library, and ProQuest. The meta-analysis was also applied for data synthesis. Moreover, heterogeneity was assessed using Cochran’s Q test and I2 index. Results: A total number of 26 RCTs were examined in this review in which the outcome variables were related to POP, UI, and FI prevalence; POP, UI, and FI severity, as well as pelvic floor muscle (PFM) strength and endurance. In most articles, UI prevalence or severity in intervention groups had significantly improved compared with those in controls. The number of studies examining POP and FI was also relatively low. In two studies, FI severity or prevalence in intervention groups had significantly enhanced in comparison with those in control groups; however, FI prevalence in two articles had been reported lower in intervention groups than that in control groups although no significant difference had been observed. There was also no significant improvement in intervention groups in two other studies in this respect. Besides, three articles had not reported traces of improvement in POP, as well as a significant difference between intervention and control groups. Nevertheless, two studies had found a significant improvement in POP in this regard. Based on meta-analysis results for the variable of PFM strength, Cochran’s Q test (P<0.001) and I2 index (90.02) indicated heterogeneity between studies; so, a random-effect meta-analysis was applied to estimate overall effect sizes. The overall mean differences following intervention between the study groups were also equal to 6.94, with a 95% CI (1.36 to 12.52). Conclusions: It was concluded that physiotherapy and PFMEs might have effects on pregnancy-related UI, but they had not consistently reduced FI severity or prevalence and failed to constantly improve POP.
