Meta-Analysis
BACKGROUND
Anemia is a wide-spread public health problem characterized by a decrease in hemoglobin concentration and/ or red blood cell volume below an established cut-off value. In developing countries including Ethiopia, about half of children are estimated to be anemic. Therefore, the purpose of this study was to determine the pooled prevalence of anemia and its predictor factors among children in Ethiopia.
METHOD
The studies were identified through explicit and exhaustive search of reputable databases (PubMed, Google scholar, Science Direct, EMBASE, Cochrane library, and the hand search of reference lists of previous prevalence studies to retrieve more related articles. Thirty-nine studies were selected based on a comprehensive list of inclusion and exclusion criteria. Data were extracted using a standardized and pre-tested data extraction checklist, and the analysis was done using STATA 14 statistical software. To assess heterogeneity, the Cochrane Q test statistic and I2 tests were used. In our analysis, considerable heterogeneity was observed. Therefore, a random effect meta-analysis model was used to estimate the pooled prevalence of anemia. Moreover, the predictor factors of anemia were examined.
RESULTS
The forest plot of 39 included studies revealed that the overall pooled prevalence of anemia among children in Ethiopia was 34.4% (95% CI: 29.1, 39.7%). Sub-group analysis showed that the highest anemia prevalence was observed in Somali Region with a prevalence of 49.4 % (95% CI: 20.9, 77.8). Also, anemia in children was found to be highest in the age group of less than five years (45.2, 95% CI: 39.6,50.8). Low literacy of families: 1.3 (95% CI: 1.1, 1.7), low family socioeconomic status: 1.9 (95% CI: 1.1,3.01.3), having housewife mothers or with no job: 1.5 (95% CI: 1.4, 1.9) and rural residence: 3.3 (95% CI: 1.7,6.1) were found to be predictors of anemia among children.
CONCLUSION
In this study, one in three children were anemic in Ethiopia. It is a moderate public health problem in children in this study. Low literacy, low socioeconomic status as well as rural residence of the families and helminthic infection of the children were found to be predictors of anemia in the children. Community and school-based interventions should be strengthened to improve the problem.

Meta-Analysis
BACKGROUND AND AIMS
Inflammatory bowel disease [IBD] comprises an immune-mediated group of chronic gastrointestinal disorders. Patients with IBD may experience extraintestinal manifestations, such as hepatobiliary complications. This meta-analysis aims to assess the prevalence of different hepatic manifestations in IBD patients.
METHODS
For this systematic review and meta-analysis, PubMed, Scopus, Web of Science, and Embase were searched until July 20, 2022, by specifying keywords for IBD, hepatic manifestations, and study type. Full texts of cohort studies in English that examined the prevalence of different hepatic manifestations were included in this study. The primary outcome was the overall prevalence of hepatic manifestations in IBD patients. For the statistical analysis, a proportion by random effect model meta-analysis was performed. The registration number for the protocol of this study in PROSPERO is CRD42022369595.
RESULTS
From the 4421 articles retrieved from the primary search, 118 met the inclusion criteria and were included in the final analysis. After a pooled analysis of 1 729 128 patients, the overall prevalence of hepatic manifestations was 3.49% (95% confidence interval [CI]: 3.31-3.68%; I2: 99.55%). The pooled prevalence of non-alcoholic fatty liver disease in 228 216 patients was 26.1% [95% CI: 22.1-30.2%; I2: 99.018%]. After pooled analysis of 9642 patients, the prevalence of primary sclerosing cholangitis was 1.67% [95% CI: 1.47-1.88%; I2: 99.10%]. The pooled prevalence of biliary stones was 4.1% [95% CI: 3.6-4.7%; I2: 97.43%]. Autoimmune hepatitis (0.51% [95% CI: 0.26-0.75%]; I2: 85.36%) and portal vein thrombosis (0.21% [95% CI: 0.08-0.33%]; I2: 97.95%) are considered as rare manifestations.
CONCLUSION
This study summarizes the prevalence and importance of different hepatic manifestations in IBD patients. These findings are crucial for the management of extraintestinal manifestations, especially hepatic manifestations, in IBD patients.

Meta-Analysis
IMPORTANCE
Two recent meta-analyses reported a high prevalence of both anxiety and depression in patients with alopecia areata (AA), as well as a positive association of AA with anxiety and depression, without distinguishing between disorders and symptoms. Yet, depression and anxiety can manifest either as symptoms identified in questionnaires or as specific diagnoses defined by Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition) or International Statistical Classification of Diseases and Related Health Problems, Tenth Revision criteria.
OBJECTIVE
To perform a large meta-analysis separating the prevalence of depressive and anxiety disorders from that of depressive and anxiety symptoms in patients with AA.
DATA SOURCES
PubMed, ScienceDirect, the Cochrane Library, Embase, and PsycINFO databases were searched from inception through August 1, 2020.
STUDY SELECTION
Studies that contained data on the prevalence of depressive or anxiety disorders or symptoms were included.
DATA EXTRACTION AND SYNTHESIS
The Meta-analysis of Observational Studies in Epidemiology (MOOSE) reporting guidelines were used. Pooled prevalence was calculated with a random effects model meta-analysis that took into account between- and within-study variability. Meta-regressions were used to study the association between variations in prevalence and study characteristics.
MAIN OUTCOMES AND MEASURES
The prevalence of depressive and anxiety disorders and symptoms in patients with AA.
RESULTS
Thirty-seven articles (29 on depression and 26 on anxiety) that met the inclusion criteria were identified. By distinguishing between disorders and symptoms, the prevalence of both depressive disorders (9%) and unspecified anxiety disorders (13%) in patients with AA was shown to be greater than that in the general population. The prevalence and odds ratio (OR) of depressive disorders (prevalence, 9%; OR, 1.38) and anxiety disorders of which each category had been specifically studied (prevalence, 7%-17%; OR, 1.51-1.69) were markedly lower than that of depressive symptoms (prevalence, 37%; OR, 2.70) and anxiety symptoms (prevalence, 34%; OR, 3.07). Meta-regressions showed that variations in prevalence were mainly associated with methodological differences between studies.
CONCLUSIONS AND RELEVANCE
In this systematic review and meta-analysis, the separate analyses showed that 7% to 17% of patients with AA had depressive or anxiety disorders that require psychiatric care, including specific medication. Additionally, more than one-third of patients had symptoms that are warning signs and that need monitoring because they can develop into disorders.

Meta-Analysis
BACKGROUND
Oral pigmentation is due to the accumulation of one or more pigments in tissues, causing changes in the color of the oral mucosal surfaces. Understanding the exact global prevalence of oral pigmentation and its associated factors helps researchers make the proper interventions at the right time; in this respect, the objective of the present systematic review and meta-analysis was to determine the global prevalence of oral pigmentation and its related factors.
METHOD
A systematic review and meta- analysis were conducted using the following databases: Magiran, SID, Scopus, Embase, PubMed, Web of Science (WoS), and Google Scholar. The search was run to retrieve articles published from inception until July 2021, and the following keywords were applied in the search strategy: "Epidemiolo*", "Prevalen*", "Factor*", "Pigment*", "Mouth", and "Oral". The I index was used to assess the heterogeneity of the studies, and Egger's test was used to examine the publication bias.
RESULTS
Sixty-nine articles, with a sample size of 70,668 people, meeting the inclusion criteria were included in the study. The pooled of prevalence of oral pigmentation was estimated to be 20.8% (95% confidence interval: 17.1-1.25%). The prevalence of oral pigmentation raised significantly towards the end of the timespan covered by the study (P˂ 0.001). The majority of the examined studies reported that the prevalence of oral pigmentation is significantly higher in men, smokers or those exposed to secondhand smoke, people with fair skin, and who were affected by Yusho patients.
CONCLUSION
The results of the present study show that the prevalence of oral pigmentation is high, with higher prevalence in men, smokers or those exposed to cigarette smoke, people with fair skin, and Yusho patients compared to other groups. It is recommended that. these findings be used in policy makers' decisions to deliver better health care.

Meta-Analysis Review
In this study, we aimed to conduct a meta-analysis on the results of eligible studies to estimate the prevalence of asthma, COPD, and Chronic bronchitis in Iran. International and Iranian databases including PubMed, Scopus, Web of Science, Iranmedex, and scientific information database (SID) were searched for population-based studies that had reported the prevalence of asthma and COPD from 1990 to 2015. We conducted the meta-analysis using metaprop application of Stata statistical software. I-Squared was used for calculating heterogeneity among the studies. To determine causes of heterogeneity, subgroup analysis and meta-regression method were used. Based on the results of random effect method, the overall prevalence of asthma ever was 4.56% (3.76%-5.36%) among men while it was 4.17% (3.42%-4.91%) among women. Pooled prevalence of current asthma was 7.95% while confidence interval changed from 5.85% to 10.06% (men 5.83% (2.75%-8.92%), women 9.13% (3.35%-14.94%)). Also based on the results of random effect model pooled prevalence of chronic bronchitis of five studies was 5.57%. It seems that the total crude prevalence of current asthma in Iran is less than many other countries such as Kuwait, Lebanon, Thailand, Japan, Australia and Germany and is higher than some other countries such as Oman, Pakistan, South Korea, India, China, Taiwan, Indonesia, Spain, Russia, and Greece. On the other hand, Iran is in middle situation in terms of the prevalence current asthma. Our results can fill the information and knowledge gaps about the status of the prevalence of respiratory diseases in Iran.

Meta-Analysis Review
INTRODUCTION
The objective of this review is to synthesise and present the best available evidence on the prevalence, predictors and information needs about sexual health among female Arab cancer survivors.
METHODS
The databases searched included MEDLINE, Embase and CINAHL from inception of the database until March 2020. The review was undertaken according to the JBI guidelines. Proportional meta-analysis using a random effects model was used for statistical pooling through JBI SUMARI.
RESULTS
Seven studies involving female Arab cancer survivors were included in the review. The overall prevalence of sexual dysfunction ranged from 16.7 to 67% (pooled estimate 51%, 95% CIs 21.7% to 80.2%). Dyspareunia and erectile dysfunction were the two main types of sexual dysfunction reported after diagnosis, and the overall prevalence ranged from 42.5% to 65% and 38% to 61%, respectively. The prevalence of vaginal dryness was ranged from 19.8% to 54.2%, and dyspareunia ranged from 22.2% to 65%. The lack of sexuality information and communication with health care providers (HCPs) was also reported in the included studies.
CONCLUSION
Cancer and its treatment may result in significant difficulties with sexual activity and sexual functioning among cancer survivor. Communication between the health care professionals and cancer survivors is essential to overcome this problem and improve the quality of life of female Arab cancer survivors.

Meta-Analysis Review
CONTEXT
Despite the large body of literature on breakthrough cancer pain (BTcP), an accurate estimate of BTcP prevalence is still not available.
OBJECTIVES
To provide an estimate of BTcP prevalence and investigate the association between different prevalence rates and possible determinants.
METHODS
We conducted MEDLINE and EMBASE searches for studies published from 1990 to 2012 reporting data on BTcP prevalence in adult cancer populations. Pooled prevalence rates from observational studies with an acceptable methodological quality were computed. The association between BTcP prevalence and possible predictors was investigated using subgroup analyses and meta-regression.
RESULTS
Twenty-seven observational studies were identified. When quality criteria were applied, only 19 studies were included in the pooled analysis. The overall pooled prevalence was 59.2%, with high heterogeneity. The lowest prevalence rates were detected in studies conducted in outpatient clinics (39.9%), and the highest prevalence was reported in studies conducted in hospice (80.5%). The association between BTcP prevalence and other determinants such as publication year, age, gender, metastatic disease prevalence, or baseline pain intensity did not reach statistical significance.
CONCLUSION
In the context of a large between-studies heterogeneity, more than one in two patients with cancer pain also experiences BTcP, with some variability according to clinical and organizational variables.

Meta-Analysis Review
The dissociative subtype of post-traumatic stress disorder (PTSD-DS) was introduced in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), and is characterised by symptoms of either depersonalisation or derealisation, in addition to a diagnosis of post-traumatic stress disorder (PTSD). This systematic review and meta-analysis sought to estimate the point prevalence of current PTSD-DS, and the extent to which method of assessment, demographic and trauma variables moderate this estimate, across different methods of prevalence estimation. Studies included were identified by searching MEDLINE (EBSCO), PsycInfo, CINAHL, Academic Search Complete and PTSDpubs, yielding 49 studies that met the inclusion criteria ( = 8214 participants). A random-effects meta-analysis estimated the prevalence of PTSD-DS as 38.1% (95% CI 31.5-45.0%) across all samples, 45.5% (95% CI 37.7-53.4%) across all diagnosis-based and clinical cut-off samples, 22.8% (95% CI 14.8-32.0%) across all latent class analysis (LCA) and latent profile analysis (LPA) samples and 48.1% (95% CI 35.0-61.3%) across samples which strictly used the DSM-5 PTSD criteria; all as a proportion of those already with a diagnosis of PTSD. All results were characterised by high levels of heterogeneity, limiting generalisability. Moderator analyses mostly failed to identify sources of heterogeneity. PTSD-DS was more prevalent in children compared to adults, and in diagnosis-based and clinical cut-off samples compared to LCA and LPA samples. Risk of bias was not significantly related to prevalence estimates. The implications of these results are discussed further.

Review
BACKGROUND
To review the prevalence and impact of generalized anxiety disorder (GAD) below the diagnostic threshold and explore its treatment needs in times of scarce healthcare resources.
METHODS
A systematic literature search was conducted until January 2013 using PUBMED/MEDLINE, PSYCINFO, EMBASE and reference lists to identify epidemiological studies of subthreshold GAD, i.e. GAD symptoms that do not reach the current thresholds of DSM-III-R, DSM-IV or ICD-10. Quality of all included studies was assessed and median prevalences of subthreshold GAD were calculated for different subpopulations.
RESULTS
Inclusion criteria led to 15 high-quality and 3 low-quality epidemiological studies with a total of 48,214 participants being reviewed. Whilst GAD proved to be a common mental health disorder, the prevalence for subthreshold GAD was twice that for the full syndrome. Subthreshold GAD is typically persistent, causing considerably more suffering and impairment in psychosocial and work functioning, benzodiazepine and primary health care use, than in non-anxious individuals. Subthreshold GAD can also increase the risk of onset and worsen the course of a range of comorbid mental health, pain and somatic disorders; further increasing costs. Results are robust against bias due to low study quality.
CONCLUSIONS
Subthreshold GAD is a common, recurrent and impairing disease with verifiable morbidity that claims significant healthcare resources. As such, it should receive additional research and clinical attention.

BACKGROUND
The prevalence of allergic bronchopulmonary aspergillosis (ABPA) in asthmatic patients remains unclear and is likely different across geographic locales.
OBJECTIVE
To systematically review the literature for estimating the prevalence of Aspergillus sensitization (AS) and ABPA in adults with bronchial asthma.
METHODS
We searched the PubMed and Embase databases for studies reporting the prevalence of AS or ABPA in at least 50 asthmatic subjects. The primary outcome was to assess the prevalence of ABPA. The secondary outcome was to evaluate the prevalence of AS in asthma and that of ABPA in asthma with AS. We pooled the prevalence estimates using a random-effects model and examined the factors influencing the prevalence using multivariate meta-regression.
RESULTS
Of the 11,801 records retrieved, 86 studies with 25,770 asthmatic subjects met the inclusion criteria. Most of the studies were from tertiary care centers. The pooled prevalence of ABPA in asthma (47 studies; 9822 asthmatic subjects) was 11.3% (95% CI, 8.7-14.2). The pooled prevalence of AS in asthma (73 studies; 23,003 asthmatic subjects) was 25.1% (95% CI, 20.5-30.0), whereas the prevalence of ABPA in AS (36 studies; 2954 asthmatic subjects) was 37.0% (95% CI, 27.9-46.6). Multivariate meta-regression identified studies published from India (odds ratio, 1.11; 95% CI, 1.01-1.23) as the only factor associated with higher ABPA prevalence. There was presence of significant statistical heterogeneity and publication bias.
CONCLUSIONS
We found a high prevalence of ABPA in adult asthmatic subjects, underscoring the need for screening for ABPA in all asthmatic subjects seeking tertiary care.
