Background: Anterior fontanel is an integral element of an infant craniofacial system. There are six fontanels in the newborn skull, namely anterior, posterior, two mastoid, and two sphenoid fontanels. The anterior fontanel is the largest, prominent, and most important for clinical evaluation. Sex, race, genetics, gestational age, and region are the principal factors that influence anterior fontanel size. There exist inconclusive findings on the size of anterior fontanel in newborns. Therefore, this systematic review and meta-analysis aimed to determine the pooled mean size of anterior fontanel among term newborns and to identify the pooled mean difference of anterior fontanel size between males and females.Methods: PubMed/Medline, Google Scholar, Science Direct, JBI Library, embase, and Cochrane Library databases were systematically searched. All essential data were extracted using a standardized data extraction format. The heterogeneity across studies was assessed using the Cochrane Q test statistic, I2 test statistic, and p-values. A fixed-effect model and random effect model were used to estimate the pooled mean size of anterior fontanel and the pooled mean difference between male newborns and female newborns, respectively. To deal with heterogeneity, sub-group analysis, meta-regression analysis, and sensitivity analysis were considered. JBI quality appraisal checklist was used to evaluate the quality of studies.Results: In this meta-analysis, 8, 661 newborns were involved in twenty-six studies. Among studies, 13 conducted in Asia, 7 in Africa, 5 in America, and 1 in Europe. The pooled mean size of anterior fontanel was 2.58 cm (95% CI: 2.31, 2.85 cm). The pooled mean size of anterior fontanel for Asia, Africa, America, and Europe region was 2.49, 3.15, 2.35, and 2.01 cm, respectively. A statistically significant mean difference was detected between male and female newborns (D + L pooled MD = 0.15 cm, 95% CI: 0.02, 0.29 cm).Conclusion: The pooled estimate of this review does provide the mean value of the anterior fontanel size in the newborns. There was a statistically significant mean fontanel size difference between male and female newborns. Therefore, male newborns had a significantly larger mean size than female newborns.

Abstract Background Neural tube defects are common congenital anomalies that result from early malformation in the development of the spinal cord and brain. It is related to substantial mortality, morbidity, disability, and psychological and economic costs. The aim of this review is to determine the pooled birth prevalence of neural tube defects and associated risk factors in Africa. Methods The first outcome of this review was the pooled birth prevalence of the neural tube defects and the second outcome was the pooled measure of association between neural tube defects and associated risk factors in Africa. We systematically searched PubMed, PubMed Central, Joanna Briggs Institute, Google Scopus, Cochrane Library, African Journals Online, Web of Science, Science Direct, Google Scholar, and Medline databases. The heterogeneity of studies was assessed using the Cochrane Q test statistic, I2 test statistic, and, visually, using Forest and Galbraith’s plots. A random-effect model was applied to get the pooled birth prevalence of neural tube defects. Subgroup, sensitivity, meta-regression, time-trend, and meta-cumulative analyses were undertaken. The fixed-effect model was used to analyze the association between neural tube defects and associated risk factors. Results Forty-three studies with a total of 6086,384 participants were included in this systematic review and meta-analysis. The pooled birth prevalence of the neural tube defects was 21.42 (95% CI (Confidence Interval): 19.29, 23.56) per 10,000 births. A high pooled birth prevalence of neural tube defects was detected in Algeria 75 (95% CI: 64.98, 85.02), Ethiopia 61.43 (95% CI: 46.70, 76.16), Eritrea 39 (95% CI: 32.88, 45.12), and Nigeria 32.77 (95% CI: 21.94, 43.59) per 10,000 births. The prevalence of neural tube defects has increased over time. Taking folic acid during early pregnancy, consanguineous marriage, male sex, and substance abuse during pregnancy were assessed and none of them was significant. Conclusions The pooled birth prevalence of neural tube defects in Africa was found to be high. The risk factors evaluated were not found significant.

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.

Background: Earthworm, also called dilong (Chinese language), has been used as a traditional Chinese medicine for thousands of years. Recently, some scientists believe that earthworm extracts (EE) can promote wound healing. However, its effectiveness remains controversial. We conducted a meta-analysis to evaluate the effect of EE on wound healing based on the healing rate.Methods: We comprehensively reviewed literature that mentioned EE for wound healing in the PubMed, Cochrane Library, Embase, Web of Science, China National Knowledge Infrastructure (CNKI), VIP database for Chinese Technical Periodicals, and WanFang database that have been published until January 2021. We computed weighted mean difference (WMD) for analysis with RevMan 5.3 software in animal and human models groups. Two researchers independently selected studies and evaluated the risk of bias with the Cochrane Collaboration tool. The quality of the evidence was assessed with the Cochrane risk of bias tool. This study is registered on PROSPERO (CRD42020168400).Results: From 2,486 articles, we selected 16 studies for analysis. EE treatment was associated with improvements in wound healing performance based on wound healing rate (mouse model: weighted mean difference (WMD) = 3.55, 95% confidence interval (CI): 2.34–4.77, p &lt; 0.00001; rat model: WMD = 17.29, 95% CI: 5.75–28.82, p = 0.003; rabbit model: WMD = 19.29, 95% CI: 9.95–28.64, p &lt; 0.0001). Clinical studies also confirmed that EE could reduce healing time in hospital (WMD = −8.94, 95% CI: −17.75 to −0.14, p = 0.05).Conclusion: The results of this meta-analysis demonstrated the efficacy of EE on wound healing process. As a corollary, EE can be a useful natural product for wound healing drug development.Systematic Review Registration:https://www.crd.york.ac.uk/PROSPERO/display_record.php?RecordID=168400, identifier CRD42020168400.

AbstractObjectiveThe present study aimed to review the association of conjugated linoleic acid (CLA) consumption in two forms, foods enriched in CLA and CLA supplements, with serum lipid profile in human studies.DesignSystematic review and meta-analysis.SettingSearch process was conducted in PubMed, Cochrane Library, Google Scholar, Scopus and Science Direct. Clinical trials that investigated the association of CLA intakes either in the form of supplements or enriched foods with lipid profile in healthy adults were included. All outcomes were recorded as continuous variables, and the effect size was measured by analysis of the mean and standard deviation before and after the intervention for case and control groups.SubjectsHealthy adult population.ResultsCLA supplementation was associated with a significant decrease in LDL cholesterol (mean difference=−0·218; 95 % CI −0·358, −0·077;P=0·002), a non-significant decrease in HDL cholesterol (mean difference=−0·051; 95 % CI −0·188, 0·086;P=0·468), a non-significant increase in total cholesterol (mean difference=0·009; 95 % CI −0·128, 0·146;P=0·896) and a non-significant decrease in TAG (mean difference=−0·065; 95 % CI −0·20, 0·07;P=0·344). Foods enriched with CLA were associated with significantly decreased LDL cholesterol (mean difference=−0·231; 95 % CI −0·438, −0·024;P=0·028), non-significantly increased HDL-C (mean difference=0·075; 95 % CI −0·121, 0·270;P=0·455), non-significantly decreased total cholesterol (mean difference=−0·158; 95 % CI −0·349, 0·042;P=0·124) and non-significantly decreased TAG (mean difference=−0·078; 95 % CI −0·274, 0·117;P=0·433).ConclusionsAccording to our analysis, consumption of foods enriched with CLA or CLA supplements has favourable effects on LDL cholesterol levels.

Background: Acne vulgaris (AV) is a chronic inflammatory disease of the pilosebaceous follicular unit that often occurs. Acne is a skin disorder that is not life-threatening but is mostly complained of because it is aesthetically disruptive, which can cause significant psychological problems for sufferers. The management of acne vulgaris in female patients has its challenges. There are many histories of failed therapy using conventional therapy, such as with antibiotics or isotretinoin, and female patients have a predisposition to the condition of androgen excess. Also, the increasing awareness about limiting the use of antibiotics to prevent resistance in dermatological cases, including acne vulgaris, encourages other treatment options in the female patient population, one of which is hormone-based therapy. A systematic review and meta-analysis were performed of randomized clinical trials assessing the effects of Hormone Based Therapies (Spironolactone and Combined Oral Contraceptives) in the management of Acne Vulgaris in Women. Methods: Medline Pubmed, Scopus, Cochrane Library, the reference list, conference proceedings, researchers in the field of eligible studies were searched. Ten studies (n=1906 sub-jects) were included in qualitative analysis, of which two studies (n=1842 subjects) were included in the meta-analysis. The age of the participant was greater than 14 years old. Intervention using combined oral contraceptives (n=8) or oral spironolactone (n=2). Duration of intervention (minimum six months for COC and three months for SL) and out-comes of mean difference number of acne vulgaris lesions before and after treatment. Results: Pooling of data using random-effects model found a significant difference in the mean difference in the number of lesions after treatment in the group receiving hormone-based therapy (spironolactone and combined oral contraceptives) and those receiving control therapy (p = 0.005). The overall mean difference was -0.890 ± 0.316. A negative value indicating the number of lesions after hormone-based therapy (spironolactone and combined oral contraceptives) was significantly lower than those receiving control therapy (p = 0.005). Conclusion: From the results of the systematic review and meta-analysis conducted, it can be concluded that in the group given hormone-based therapy (spironolactone and Combined Oral Contraceptives), there was a decrease in the total number of acne vulgaris lesions compared to before treatment, and the mean difference in the number of lesions was significantly lower after getting hormone-based therapy (spironolactone and combined oral contraceptives) compared with controls.

This systematic review and meta-analysis aimed to evaluate the effect of betamethasone and dexamethasone on biophysical profile (BPP) parameters. In addition, it was performed in 2017, using several databases such as PubMed/MEDLINE, Scopus, EMBASE, Cochrane library, ISI Web of science, Proquest, and Google scholar, along with Magiran SID and IranMedex. Eligible studies were selected by two reviewers and the outcomes of interest were extracted as well. Meta-analysis was done using the random effect model. Further, I-square statistic test was used for heterogeneity analysis and the presence of publication bias was also checked. At last, 12 studies were included and a random and fixed effect model was used for analysis. The pooled event rates were 4.5% (95% CI = 0.01-64.3, P=0.1), 76.8% (% 95 CI=33.5-95.6, P=0.21), 71.8% (% 95 CI=38.8-91.1, P=0.18), 70.9% (%95 CI=38.4-90.5, P=0.20), and 92.3% (%95 CI=76.0-97.8, P<0.001) for the reduced amniotic fluid volume, baseline fetal heart rate reactivity, fetal breathing, fetal movement, and heart rate variability, respectively. In summary, a significant decrease was observed in heart rate variability following betamethasone and dexamethasone administration. However, further systematic reviews are necessary to differentiate steroid induced changes in the fetal BPP from those due to fetal compromise

Abstract Glycemic variability (GV) has been an emerging target for preventing complications related to type 2 diabetes. For reducing GV, DPP-IV inhibitors have shown effectiveness compared to other oral anti-hyperglycemic drugs (OADs), but systematic evaluation has yet to be existed. A systematic review and meta-analysis of randomized controlled trials (RCTs) were performed to evaluate the effect of DPP-IV inhibitors compared with other OADs, on GV as measured by mean amplitude of glycemic excursions (MAGE). Searches were conducted using Pubmed, EMBASE, and the Cochrane Library, from which eligible studies were retrieved; seven RCTs were included in the analysis. DPP-IV inhibitors were found to significantly reduce MAGE compared to other OADs (mean difference = −14.61; 95% CI = −19.00 to −10.21; p < 0.0001) without significant heterogeneity among sulfonylureas (mean difference = −14.93; 95% CI = −21.60 to −8.26; p < 0.0001). Initial combination therapy with DPP-IV inhibitors more effectively reduced MAGE than stepwise add-on therapies (p = 0.006), although no differences in MAGE were found based on HbA1c values. These findings indicate that DPP-IV inhibitors are promising alternatives for reducing GV in type 2 diabetes patients. However, further studies utilizing larger numbers of patients and longer-term follow-ups are needed.

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.

<b><i>Objective:</i></b> Hyponatremia is a common electrolyte disorder in patients with stroke, which leads to various fatal complications. We performed a systematic review and meta-analysis to investigate the outcomes of acute stroke patients with hyponatremia. <b><i>Methods:</i></b> We searched MEDLINE, EMBASE, and the Cochrane Library databases for relevant literature in English published up to March 2020. Two review authors independently screened and selected the studies by assessing the eligibility and validity based on the inclusion criteria. Mortality at 90 days was set as the primary end point, and in-hospital mortality and length of hospital stay were set as the secondary end points. We conducted the data synthesis and analyzed the outcomes by calculating the odds ratio (OR) and mean difference. <b><i>Results:</i></b> Of 835 studies, 15 studies met the inclusion criteria (<i>n</i> = 10,745). The prevalence rate of stroke patients with hyponatremia was 7.0–59.2%. They had significantly higher 90-day mortality (OR, 1.73; 95% confidence interval (CI), 1.24–2.42) and longer length of hospital stay (mean difference, 10.68 days; 95% CI, 7.14–14.22) than patients without hyponatremia. Patients with hyponatremia had a higher tendency of in-hospital mortality than those without hyponatremia (OR, 1.61; 95% CI, 0.97–2.69). <b><i>Conclusions:</i></b> The development of hyponatremia in the clinical course of stroke is associated with higher short-term mortality and a longer hospital stay. Although the causal relationship is unclear, hyponatremia could be a significant predictor of poor outcomes after stroke.
