Meta-Analysis Review
Background McArdle disease (Glycogen Storage Disease type V) is caused by an absence of muscle phosphorylase leading to exercise intolerance,myoglobinuria rhabdomyolysis and acute renal failure. This is an update of a review first published in 2004.Objectives To review systematically the evidence from randomised controlled trials (RCTs) of pharmacological or nutritional treatments for improving exercise performance and quality of life in McArdle disease.Search methods We searched the Cochrane Neuromuscular Disease Group Specialized Register, CENTRAL, MEDLINE and EMBASE on 11 August 2014.Selection criteria We included RCTs (including cross-over studies) and quasi-RCTs. We included unblinded open trials and individual patient studies in the discussion. Interventions included any pharmacological agent or nutritional supplement. Primary outcome measures included any objective assessment of exercise endurance (for example aerobic capacity (VO2) max, walking speed, muscle force or power and fatigability). Secondary outcome measures included metabolic changes (such as reduced plasma creatine kinase and a reduction in the frequency of myoglobinuria), subjective measures (including quality of life scores and indices of disability) and serious adverse events.Data collection and analysis Three review authors checked the titles and abstracts identified by the search and reviewed the manuscripts. Two review authors independently assessed the risk of bias of relevant studies, with comments from a third author. Two authors extracted data onto a specially designed form.Main results We identified 31 studies, and 13 fulfilled the criteria for inclusion. We described trials that were not eligible for the review in the Discussion. The included studies involved a total of 85 participants, but the number in each individual trial was small; the largest treatment trial included 19 participants and the smallest study included only one participant. There was no benefit with: D-ribose,glucagon, verapamil, vitamin B6, branched chain amino acids, dantrolene sodium, and high-dose creatine. Minimal subjective benefit was found with low dose creatine and ramipril only for patients with a polymorphism known as the D/Dangiotens in converting enzyme(ACE) phenotype. A carbohydrate-rich diet resulted in better exercise performance compared with a protein-rich diet. Two studies of oral sucrose given at different times and in different amounts before exercise showed an improvement in exercise performance. Four studies reported adverse effects. Oral ribose caused diarrhoea and symptoms suggestive of hypoglycaemia including light-headedness and hunger. In one study, branched chain amino acids caused a deterioration of functional outcomes. Dantrolene was reported to cause a number of adverse effects including tiredness, somnolence, dizziness and muscle weakness. Low dose creatine (60 mg/kg/day) did not cause side-effects but high-dose creatine (150 mg/kg/day) worsened the symptoms of myalgia.Authors' conclusions Although there was low quality evidence of improvement in some parameters with creatine, oral sucrose, ramipril and a carbohydrate rich diet, none was sufficiently strong to indicate significant clinical benefit.

Review
BACKGROUND
Facial paralysis has a debilitating impact on facial function, especially the eyebrow. Static procedures have long been the standard treatment strategy, but in more recent years, dynamic procedures are being developed. To reconstruct the upper branches of the facial nerve (temporal and zygomatic branches), the deep temporal nerve (DTN) and its branches, with its close proximity to the eyebrow, can be used as a possible donor nerve for reinnervation. This systematic review provides an overview of the DTN anatomy and possible surgical treatment strategies.
MATERIALS AND METHODS
A PubMed systematic literature search was performed in October 2021. Studies on cadavers and clinical studies providing anatomical or surgical information on the dissection of the DTN as well as surgical treatment strategies using the DTN were included.
RESULTS
The literature search produced 311 results, including 36 duplicates. After screening on title and abstract, 11 studies were found possibly relevant and underwent a full-text critical appraisal, resulting in 4 exclusions. In total seven studies were included. The data gathered were used to adequately describe the DTN anatomy, surgical approaches and landmarks used during surgery.
CONCLUSION
The DTN and its branches prove to be a viable donor for the reconstruction of facial nerve branches, since the location and anatomical consistency can be relied upon through a multitude of studies, especially of the middle branch. Our study describes anatomy and nerve characteristics for its use in facial reanimation.

Review
BACKGROUND
Although sexual function (SF) and sexual satisfaction (SS) are the essential factors influenced negatively by infertility and may be associated with delaying or disrupting infertility treatment, no systematic review has assessed the results of these studies so far.
OBJECTIVE
The present study aimed to systematically review published interventional research regarding SF and SS among infertile individuals.
MATERIALS AND METHODS
In this systematic review, the databases of PubMed, MEDLINE, Web of Science, Scopus, ScienceDirect, Cochrane Library, PsycInfo, Google Scholar, and SID were searched to retrieve the relevant studies in Persian and English languages up to August 2021.
RESULTS
23 interventional studies were included in this systematic review, of which only 2 were low quality based on the critical appraisal skills program checklist. The interventions of the included studies were classified into 2 main categories: educational and psychological interventions for increasing the SF and SS among infertile women or couples.
CONCLUSION
There was no clear evidence to understand the most effective method for increasing SF and satisfaction among couples with infertility. Based on the results of the included studies, all of them showed the effectiveness of the various interventions performed on sexual health dimensions among couples with infertility. This systematic review showed that most SF studies were educational, whereas the SS were more psychologically interventional. Conducting standardized and high-quality randomized controlled trials focusing on SF and SS is recommended.

Review
Several anatomical variations of the iliohypogastric nerve branches have been observed in earlier studies. Knowledge of these variations is useful for the improvement of peripheral nerve blocks and avoidance of iatrogenic nerve injuries during surgeries. The purpose of this study was to perform a systematic review of the literature about the anatomical topography and variations of the iliohypogastric nerve. An extensive search on PubMed, Scopus, and Web of Science electronic databases was conducted by the first author in November 2021, based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Anatomical or cadaveric studies about the origin, the course, and the distribution of the iliohypogastric nerve were included in this review. Thirty cadaveric studies were included for qualitative analysis. Several anatomical variations of the iliohypogastric nerve were depicted including its general properties, its origin, its branching patterns, its course, its relation to anatomical landmarks, and its termination. Among them, the absence of the iliohypogastric nerve ranged from 0 to 34%, its origin from L1 ranged from 62.5 to 96.5%, and its isolated emergence from psoas major ranged from 47 to 94.5%. Numerous anatomical variations of the iliohypogastric nerve exist but are not commonly cited in classic anatomical textbooks. The branches of the iliohypogastric nerve may be damaged during spinal anesthesia and surgical procedures in the lower abdominal region. Therefore, a better understanding of the regional anatomy and its variations is of vital importance for the prevention of iliohypogastric nerve injuries.

Review
The goal of this study was to systematically review the published data on dengue virus (DENV) seroprevalence in Sudan and to estimate disease burden through meta-analysis. We searched, reviewed, and extracted online available reports on DENV in Sudan. Among 168 identified records, 19 were selected. Dengue infections were documented in 11/18 states. The overall seroprevalence of DENV in Sudan was estimated to be 27%, while the prevalence of dengue IgM was 22% and IgG was 38%. The prevalence of dengue estimated from community and hospital-based cross-sectional studies were 26% and 30% respectively. Additionally, one cohort study and a single PCR-based study reported a prevalence of 1% and 4%, respectively. Regional analysis revealed that the variation in seroprevalence in East, North, West, and Central Sudan was 23%, 24%, 36% and 43%, respectively. Interestingly, we found that DENV is circulating countrywide with a significant spatiotemporal variation in the disease seroprevalence. Furthermore, publications on dengue prevalence are temporally and geographically fragmented, perhaps due to limited resources. However, this gap in data and knowledge highlights the urgent need for a country-wide surveillance system and continued study of dengue burden in Sudan to accurately estimate the disease prevalence and determine the associated risk factors.

BACKGROUND
The aim of this systematic review is to evaluate the changes in gut microbiota (GM) induced by the Ketogenic Diets (KD) as a potential underlying mechanism in the improvement of neurological diseases.
METHODS
A comprehensive search was conducted on three electronic databases, including PubMed/Medline, Web of Science, and Scopus until December 2022. The inclusion criteria were studies that described any changes in GM after consuming KD in neurological patients. Full text of studies such as clinical trials and cohorts were added. The quality assessment of cohort studies was conducted using the Newcastle-Ottawa Quality Assessment Scale and for the clinical trials using the Cochrane Collaboration tool. The search, screening, and data extraction were performed by two researchers independently.
RESULTS
Thirteen studies examining the effects of the KD on the GM in neurological patients were included. Studies have shown that KD improves clinical outcomes by reducing disease severity and recurrence rates. An increase in Proteobacteria phylum, Escherichia, Bacteroides, Prevotella, Faecalibacterium, Lachnospira, Agaricus, and Mrakia genera and a reduction in Firmicutes, and Actinobacteria phyla, Eubacterium, Cronobacter, Saccharomyces, Claviceps, Akkermansia and Dialister genera were reported after KD. Studies showed a reduction in concentrations of fecal short-chain fatty acids and branched-chain fatty acids and an increase in beta Hydroxybutyrate, trimethylamine N-oxide, and N-acetylserotonin levels after KD.
CONCLUSION
The KD prescribed in neurological patients has effectively altered the GM composition and GM-derived metabolites.

Review
BACKGROUND
Malnutrition is a major public health issue worldwide. It has significant consequences, including weakened immune systems, which may lead to increased incidences of infectious disease and higher mortality, particularly in children. A systematic review and meta-analysis were conducted to estimate the overall prevalence of malnutrition (wasting, underweight, and stunting) among children of 6-14 years of age in Iran.
METHODS
Data were collected in 2018 based on searches of the PubMed, Science Direct, Scopus, Google Scholar, Science Information Database (SID), Magiran, Irandoc, and Iranmedex databases using the following keywords: childhood, childhood malnutrition, children, nutrition, malnutrition, wasting, underweight, stunting, child, student, boy, girl, cause, prevalence, and Iran, in order to identify studies eligible for inclusion in the review. Comprehensive Meta-Analysis, version 2 (CMA: 2) was used to estimate the overall prevalence of malnutrition.
RESULTS
Nine out of 328 articles were included in our analyses. The overall of wasting among children of 6-14 years of age in Iran based on the random-effects model (according to nine studies and 18,296 participants) was 12.5% (95% Confidence Interval, 7.1-21.2). The overall prevalence of underweight based on the random-effects model (according to 10 studies and 19,185 participants) was 19% (95% CI, 8.1-38.6). Also, the overall prevalence of stunting based on the random-effects model (according to 10 studies and 19,185 participants) was 20% (95% CI, 9.4-37.8).
CONCLUSIONS
The results of this study show that the prevalence of malnutrition among 6-14-year-old children in Iran is similar to the global average. We need solutions that can be used for both prevention and reduction of malnutrition, especially in areas with middle or low socioeconomic status. It is necessary to identify factors associated with malnutrition in various geographic regions in order to implement appropriate programs based on factors with the highest impact in each region.

BACKGROUND
There is no summative quantitative study that report the difference in BMI in high screen user children and adolescents or give a difference in screen time in children and adolescents with obesity vs. children and adolescents without obesity. In the current meta-analysis we systematically summarized the association between obesity and screen time and meta-analyzed the results.
METHODS
A systematic search from Scopus, PubMed and Embase electronic databases. Studies that evaluated the association between screen time and obesity up to June 2021.
RESULTS
Results revealed that those at the highest screen time category had 0.7 kg/m higher BMI (WMD = 0.703; CI = 0.128, 1.278; < 0.016; = 95.8%). Moreover, children and adolescents with obesity had a mean value of 0.313 h higher screen time compared with children and adolescents without obesity (WMD: 0.313; OR = 0.219, 0.407; < 0.001; = 96%). The results of subgrouping showed that study quality, continent and sample size could reduce the heterogeneity values. No evidence of publication bias was reported according to visual asymmetry of funnel plots and the results of Begg's and Egger's tests.
CONCLUSION
For the first time, the current systematic review and meta-analysis revealed a positive association between screen time and obesity among children and adolescents. Due to the cross-sectional design of the included studies, causal inference is impossible, therefore, further studies in separate analysis of both genders are suggested to better elucidate gender-specific results.

Review
This systematic review aimed to examine the health outcomes and environmental impact of edible insect consumption. Following PRISMA-P guidelines, PubMed, Medline ProQuest, and Cochrane Library databases were searched until February 2021. Twenty-five articles met inclusion criteria: twelve animal and six human studies (randomized, non-randomized, and crossover control trials), and seven studies on sustainability outcomes. In animal studies, a supplement (in powdered form) of 0.5 g/kg of glycosaminoglycans significantly reduced abdominal and epididymal fat weight (5-40% and 5-24%, respectively), blood glucose (10-22%), and total cholesterol levels (9-10%), and a supplement of 5 mg/kg chitin/chitosan reduced body weight (1-4%) and abdominal fat accumulation (4%) control diets. In other animal studies, doses up to 7-15% of edible insect inclusion level significantly improved the live weight (9-33%), reduced levels of triglycerides (44%), cholesterol (14%), and blood glucose (8%), and increased microbiota diversity (2%) control diet. In human studies, doses up to 7% of edible insect inclusion level produced a significant improvement in gut health (6%) and reduction in systemic inflammation (2%) control diets and a significant increase in blood concentrations of essential and branched-chain amino acids and slowing of digestion (40%) whey treatment. Environmental indicators (land use, water footprint, and greenhouse gas emissions) were 40-60% lower for the feed and food of edible insects than for traditional animal livestock. More research is warranted on the edible insect dose responsible for health effects and on environmental indicators of edible insects for human nutrition. This research demonstrates how edible insects can be an alternative protein source not only to improve human and animal nutrition but also to exert positive effects on planetary health.

Meta-Analysis
BACKGROUND
Psychological empowerment is generally understood to be associated with job satisfaction among nurses. However, recently published literature has questioned this association.
OBJECTIVE
We aimed to systematically investigate through a meta-analysis the association of psychological empowerment with job satisfaction among nurses.
METHODS
PubMed, Medline, Cochrane Library, PsycInfo, and Embase were used to search targeted studies from conception to 20 January 2022. The correlation coefficients of each study were extracted and converted into Fisher's Z. Finally, pooled was calculated by Fisher's Z and standard error (SE).
RESULTS
A total of 28 studies encompassing 27 articles with 7,664 registered nurses were included. The pooled correlation coefficient between psychological empowerment and job satisfaction was 0.55. Subgroup analyses were conducted according to ethnicity, and the correlation in the Asian participants ( < 0.01) was significantly stronger ( < 0.05) than that of the Caucasian nurses ( < 0.01).
CONCLUSIONS
Psychological empowerment is strongly correlated to job satisfaction for registered nurses, especially among those from Asian countries. Interventions designed for psychological empowerment could be one of the strategies to promote the retention of nurses. Nonetheless, additional future studies are essential for more investigations.
