Review
BACKGROUND
Urinary tract infection is one of the most common health problems during pregnancy. It is most commonly reported among pregnant women and is a known reason of morbidity during pregnancy worldwide, predominantly in developing countries. The etiological agents include and others. Different risk factors expose pregnant women to urinary tract infection. Drug resistance by uropathogenic bacteria is a current problem of the world. This study was aimed at reviewing the prevalence of bacterial uropathogens and their antimicrobial resistance patterns among pregnant women in developing countries in Asia and Africa, during the past decade.
METHODS
A systematic literature search was accomplished to identify published studies between January 2005 and November 2016. The literature search strategy in this paper included searching PubMed, PMC, Science Direct, Springer open, Google scholar and BioMed Central databases.
RESULTS
The overall prevalence of UTI among pregnant women was 13.5%. Both Gram-positive and Gram-negative bacteria were isolated from all eligible studies. Gram-negative bacteria (83.7%) accounted for majority of infections while Gram positives accounted for 15.9%. Among the isolated bacteria, was the most predominant uropathogen; it was shown to be present in all 26 eligible studies that were included in this review. Four studies from Africa and four from Asia were reviewed for antimicrobial resistance patterns of uropathogenic bacteria. In most of the regions, almost all the bacterial uropathogens had high resistance to ampicillin (67.2%) whereas all the strains showed relative sensitivity to ciprofloxacin (71.2%), nitrofurantoin (65%) and ceftriaxone (74.1%).
CONCLUSION
The prevalence of UTI in the selected regions of the two continents is different. A significant prevalence of UTI among pregnant women is mainly observed in Africa and Asia. Uropathogenic bacteria showed resistance to antimicrobial drugs that are regularly used in developing countries. This may show the need to incorporate culture and drug susceptibility tests into the routine antenatal care for pregnant women and drug resistance should be monitored.

Meta-Analysis
Epidemiology of pathogens and antimicrobial resistance of nosocomial urinary tract infections in patients with spinal cord injuries in China: A systematic review and meta-analysis.
CONTEXT
Despite a high urinary tract infection (UTI) rate in spinal cord injured patents in China, there is limited evidence on the epidemiological character of that.
OBJECTIVE
The purpose of our article was to characterize the distribution of pathogens of UTI patients with spinal cord injuries (SCI) and the resistance profile of pathogens.
METHODS
A literature search of six electronic databases was carried out to identify the incidence, pathogen distribution, and drug resistance of UTI after SCI based on our inclusion and exclusion criteria. Meta-analysis was carried out using R 4.0.2 software; a subgroup analysis was performed by the year 2012.
RESULTS
We screened 1110 eligible studies, 33 were included in our final review. A total of 7271 bacterial species were included in our studies; 6092 were gram-negative (81.13% [76.83-85.11]) and 1003 were gram-positive (14.89% [11.70-18.38]). Before 2012, (45.43%) was the predominant isolated pathogen, followed by Klebsiella (7.49%) and Enterococcus (6.01%). After 2012, (50.23%) was the main pathogen, followed by Klebsiella (12.47%) and Proteus (6.88%). was more likely to be resistant to Levofloxacin, Amikacin, sulfonamides, 4th-generation cephalosporins and Nitrofurantoin before 2012 (81.8% vs. 62.9%, 32.0% vs. 7.6%, 81.3% vs. 61.6%, 81.8% vs. 24.1%, 33.5% vs. 5.1%), whereas was more frequently resistant to Inhibitor-resistant β-lactamas after 2012 (56.3% vs. 34.0%). was more likely to be resistant to Aztreonam, Amikacin before 2012 (80.0% vs. 39.8%, 48.1% vs. 19.0%). presented a high resistance to Levofloxacin, Inhibitor-resistant β-lactamas after 2012 (61.8% vs. 35.6%, 59.1% vs. 5.7%).
CONCLUSIONS
UTI in patients with SCI in China were mainly caused by gram-negative bacteria. We observed a remarkable modification in resistance profiles of pathogen distribution before 2012 and after 2012, which suggests reasonable control of the use of antibiotics has a positive effectiveness on resistance profiles.

Meta-Analysis
BACKGROUND
Antimicrobial resistance is swiftly increasing all over the world. In Africa, it manifests more in pathogenic bacteria in form of antibiotic resistance (ABR). On this continent, bacterial contamination of commonly used herbal medicine (HM) is on the increase, but information about antimicrobial resistance in these contaminants is limited due to fragmented studies. Here, we analyzed research that characterized ABR in pathogenic bacteria isolated from HM in Africa since 2000; to generate a comprehensive understanding of the drug-resistant bacterial contamination burden in this region.
METHODS
The study was conducted according to standards of the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA). We searched for articles from 12 databases. These were: PubMed, Science Direct, Scifinder scholar, Google scholar, HerbMed, Medline, EMBASE, Cochrane Library, International Pharmaceutical Abstracts, Commonwealth Agricultural Bureau Abstracts, African Journal Online, and Biological Abstracts. Prevalence and ABR traits of bacterial isolates, Cochran's Q test, and the I statistic for heterogeneity were evaluated using MedCalcs software. A random-effects model was used to determine the pooled prevalence of ABR traits. The potential sources of heterogeneity were examined through sensitivity analysis, subgroup analysis, and meta-regression at a 95% level of significance.
FINDINGS
Eighteen studies met our inclusion criteria. The pooled prevalence of bacterial resistance to at least one conventional drug was 86.51% (95% CI = 61.247-99.357%). The studies were highly heterogeneous (I = 99.17%; p < 0.0001), with no evidence of publication bias. The most prevalent multidrug-resistant species was Escherichia coli (24.0%). The most highly resisted drug was Ceftazidime with a pooled prevalence of 95.10% (95% CI = 78.51-99.87%), while the drug-class was 3 generation cephalosporins; 91.64% (95% CI = 78.64-96.73%). None of the eligible studies tested isolates for Carbapenem resistance. Extended Spectrum β-lactamase genes were detected in 89 (37.2%) isolates, mostly Salmonella spp., Proteus vulgaris, and K. pneumonia. Resistance plasmids were found in 6 (5.8%) isolates; the heaviest plasmid weighed 23,130 Kilobases, and Proteus vulgaris harbored the majority (n = 5; 83.3%).
CONCLUSIONS
Herbal medicines in Africa harbor bacterial contaminants which are highly resistant to conventional medicines. This points to a potential treatment failure when these contaminants are involved in diseases causation. More research on this subject is recommended, to fill the evidence gaps and support the formation of collaborative quality control mechanisms for the herbal medicine industry in Africa.

We performed a comprehensive systematic review of acute pyelonephritis in pregnancy using PubMed, SCOPUS, ClinicalTrials.gov, and Ovid from inception to April 2018. About 7796 references were screened for inclusion, and 52 references from 1908 to 2017 were included. One hundred seven cases of acute pyelonephritis in pregnant women were reviewed. Gestational age at diagnosis was reported as 2 (2%), 43 (40%), and 51 (52%) during the first, second, and third trimesters, respectively. Maternal complications included sepsis (49%), acute respiratory distress syndrome (47%), anaemia (33%), acute kidney injury (10%), renal abscess (6%), and death (6%). 25 preterm deliveries (23%), 6 intrauterine foetal demises (6%), 4 spontaneous abortions (4%), and 8 neonatal intensive care unit admissions (7%) were reported. Microorganisms cultured included (51%), (8%), (5%), (5%), (4%), and (3%). Early diagnosis and management led to fewer complications.Impact statement Acute pyelonephritis during pregnancy can lead to adverse pregnancy outcomes and in this article, we highlight the most common outcomes previously reported. Previous studies have reported maternal adverse outcomes and only very few stressed on fetal/neonatal outcomes. The results add that not only is maternal morbidity/mortality is increased, but also increases adverse outcomes for the fetus/neonate, such as preterm delivery and fetal/neonatal demise. The implications from this article serve to increase a medical providers knowledge on how to appropriately counsel pregnant women with acute pyelonephritis. In addition, future research can aim to understand why pregnant women are more prone to morbidity and mortality compared to nonpregnant women.

Meta-Analysis Review
Pyogenic liver abscess (PLA) is a potentially life-threatening disease in many parts of the world, especially in Asia. The aim of this study was to quantify the proportion of common pathogens in patients with PLA in China, using a meta-analysis method based on systematic review of published studies. Several electronic databases were searched to identify the studies reporting the pathogens of PLA. We performed a meta-analysis to calculate the pooled proportion of pathogens and subgroup analysis among the included studies using R 3.1.1 software. In total, 183 studies were included in our final analysis, Klebsiella spp (54 %), Escherichia spp (29 %), Enterobacter spp (9 %), Proteus spp (6 %) and Pseudomonas spp (5 %) comprised the major gram-negative bacteria. Gram-positive bacteria mainly included Staphylococcus spp (13 %), Streptococcus spp (8 %) and Enterococcus spp (7 %). The distribution of pathogens in PLA patients were different in different economic regions in China. The proportion of Klebsiella spp had an upward tendency in recent years compared to other pathogens. In addition, the proportion of common pathogens in PLA patients with diabetes mellitus (DM) were carried out indicating that the dominant pathogens were Klebsiella spp (66 %), Escherichia spp (21 %) and Enterobacter spp (11 %). This meta-analysis showed that the main pathogens of PLA were Klebsiella spp, Escherichia spp, Staphylococcus spp, and Enterobacter spp in China. To ensure a precise estimate of the epidemiology of the pathogens, further large-scale or even a population-based study is needed.

Meta-Analysis
BACKGROUND
Fluoroquinolones are among the most frequently utilized antibacterial agents in developing countries like Ethiopia. Ciprofloxacin has become the most prescribed drug within this class and remains as one of the top three antibacterial agents prescribed in Ethiopia. However, several studies indicated that there is a gradual increase of antibacterial resistance. Therefore, this meta-analysis aimed to quantitatively estimate the prevalence of ciprofloxacin resistance bacterial isolates in Ethiopia.
METHODS
Literature search was conducted from electronic databases and indexing services including EMBASE (Ovid interface), PubMed/MEDLINE, Google Scholar, Science Direct and WorldCat. Data were extracted with structured format prepared in Microsoft Excel and exported to STATA 15.0 software for the analyses. Pooled estimation of outcomes was performed with DerSimonian-Laird random-effects model at 95% confidence level. Degree of heterogeneity of studies was presented with I statistics. Publication bias was conducted with comprehensive meta-analysis version 3 software and presented with funnel plots of standard error supplemented by Begg's and Egger's tests. The study protocol has been registered on PROSPERO with reference number ID: CRD42018097047.
RESULTS
A total of 37 studies were included for this study. The pooled prevalence of resistance in selected gram-positive bacterial isolates against ciprofloxacin was found to be 19.0% (95% confidence interval [CI]: 15.0, 23.0). The degree of resistance among Staphylococcus aureus, Coagulase negative Staphyloccoci (CoNS), Enterococcus faecalis and Group B Streptococci (GBS) was found to be 18.6, 21.6, 23.9, and 7.40%, respectively. The pooled prevalence of resistance in gram-negative bacteria was about 21.0% (95% CI: 17, 25). Higher estimates were observed in Neisseria gonorrhea (48.1%), Escherichia coli (24.3%) and Klebsiella pneumonia (23.2%). Subgroup analysis indicated that blood and urine were found to be a major source of resistant S. aureus isolates. Urine was also a major source of resistant strains for CoNS, Klebsiella and Proteus species.
CONCLUSION
Among gram-positive bacteria, high prevalence of resistance was observed in E. faecalis and CoNS whereas relatively low estimate of resistance was observed among GBS isolates. Within gram-negative bacteria, nearly half of isolates in N. gonorrhoea were found ciprofloxacin resistant. From enterobacteriaceae isolates, K. pneumonia and E. coli showed higher estimates of ciprofloxacin resistance.

Comparative Study
INTRODUCTION
Inflammatory bowel diseases (IBDs) and chronic rheumatic diseases (CRDs) are systemic chronic disorders sharing common genetic, immune and environmental factors. About half of patients with IBD develop rheumatic ailments and microscopic intestinal inflammation is present in up to half of CRD patients. IBD and CRD patients also share a common therapeutic armamentarium. Disequilibrium in the complex realm of microbes (known as dysbiosis) that closely interact with the gut mucosal immune system has been associated with both IBD and CRD (spondyloarthritis and rheumatoid arthritis). Whether dysbiosis represents an epiphenomenon or a prodromal feature remains to be determined.
METHODS
In an attempt to further investigate whether specific gut dysbiosis may be the missing link between IBD and CRD in patients developing both diseases, we performed here a systematic literature review focusing on studies looking at bacterial microbiota in CRD and/or IBD patients.
RESULTS
We included 80 studies, with a total of 3799 IBD patients without arthritis, 1084 CRD patients without IBD, 132 IBD patients with arthropathy manifestations and 12 spondyloarthritis patients with IBD history. Overall, this systematic review indicates that an increase in s, and genera, as well as a decrease in genera and species belonging to Verrucomicrobia and Fusobacteria phyla are common features in IBD and CRD patients, whereas dozens of bacterial species are specific features of CRD and IBD.
CONCLUSION
Further work is needed to understand the functions of bacteria and of their metabolites but also to characterize fungi and viruses that are commonly found in these patients.

Review
INTRODUCTION
Renal stone disease has a high recurrence rate. Prompt metabolic evaluation followed by appropriate medical management is of paramount importance for preventing disease recurrence.
AREAS COVERED
A PubMed/Medline search was performed to identify randomized controlled studies evaluating medical treatments against renal stone recurrence. Due to the limited number of published randomized studies, non-randomized studies of significant importance were included and reported.
EXPERT OPINION
Thiazides are widely used for lowering calcium levels in urine and thus preventing calcium stone formation. Citrate supplements may increase the urine citrate level and increase pH. Allopurinol has shown significant efficacy for preventing formation of calcium stones in hyperuricosuric patients. Prevention of recurrence of infection stones and cystine stones has not been widely studied. Several agents that are used today have shown efficacy outside randomized controlled studies. However, they may produce severe adverse events, which are minimizing their use.

Meta-Analysis Review
OBJECTIVES
To evaluate the presence of extreme findings and fluctuation in effect size in endocrinology.
STUDY DESIGN AND SETTINGS
We systematically identified all meta-analyses published in 2014 in the field of endocrinology. Within each meta-analysis, the effect size of the primary binary outcome was compared across studies according to their order of publication. We pooled studies using the DerSimonian and Laird random-effects method. Heterogeneity was evaluated using the I(2) and tau(2).
RESULTS
Twelve percent of the included 100 meta-analyses reported the largest effect size in the very first published study. The largest effect size occurred in the first 2 earliest studies in 31% of meta-analyses. When the effect size was the largest in the first published study, it was three times larger than the final pooled effect (ratio of rates, 3.26; 95% confidence interval: 1.80, 5.90). The largest heterogeneity measured by I(2) was observed in 18% of the included meta-analyses when combining the first 2 studies or 17% when combing the first 3 studies.
CONCLUSIONS
In endocrinology, early studies reported extreme findings with large variability. This behavior of the evidence needs to be taken into account when used to formulate clinical policies.

Review
PURPOSE
The most common cause of mortality for many cancer survivors is cardiovascular disease (CVD). This requires a shift in thinking where control of CVD risk factor-related comorbidity is paramount. Our objective was to provide an understanding of adherence to medications for the management of CVD risk factor-related comorbidities among cancer survivors.
METHODS
We systematically searched for articles indexed in MEDLINE (via PubMed), Embase, Cochrane (Wiley), PsycINFO, and Scopus (via Elsevier) for articles published from inception to October 31, 2019, and updated the search on June 7, 2021. English language, original research that assessed medication adherence to common CVD risk factor-related comorbidities among cancer survivors was included. We assessed risk of bias using the Mixed Methods Appraisal Tool.
RESULTS
Of the 21 studies included, 57% focused on multiple cancer types. Seventy-one percent used pharmacy-based adherence measures. Two were prospective. Adherence was variable across cancer types and CVD risk factor-related comorbidities. Among the studies that examined changes in comorbid medication adherence, most noted a decline in adherence following cancer diagnosis and throughout cancer treatment. There was a focus on breast cancer populations.
CONCLUSIONS
CVD risk factor-related medication adherence is low among cancer survivors and declines over time. Given the risk for CVD-mortality among cancer survivors, testing of interventions aimed at improving adherence to non-cancer medications is critically needed.
IMPLICATIONS FOR CANCER SURVIVORS
For many cancer survivors, regularly taking medications to manage CVD risk is important for longevity. Engaging with primary care throughout the cancer care trajectory may be important to support cardiovascular health.
