Meta-Analysis Review
PURPOSE
Emphysematous pyelonephritis (EPN) is an acute, severe necrotising infection of the kidney. There has been a shift from early nephrectomy to conservative methods. We conducted a meta-analysis to assess the impact of risk factors and treatment choices on outcomes in EPN.
METHODS
We conducted a database search of all studies in English, reporting more than 12 patients of EPN from 1980 to 2020. We compiled the demographics, clinical presentations, risk factors, critical diagnostic results, treatment modalities and outcomes, including mortality.
RESULTS
We identified 37 observational studies, 32 retrospective and 5 prospective. The studies reported on 1146 patients, of which 790(68.9%) were female, and 946 (82.5%) were diabetic. In addition, 184 (16.1%) patients had stones, and 235 (20.5%) had obstructive uropathy. Fever and flank pain were the most frequent symptoms. The most common clinical features were pyuria, fever, flank tenderness, and tachycardia. E. coli, Klebsiella pneumoniae and Proteus were the most frequent organisms isolated. X-ray KUB and ultrasound were used as initial diagnostic modalities, but CT scan was the usual diagnostic and confirmatory investigation. Confusion, shock, thrombocytopenia, sepsis, emergency nephrectomy and hyponatremia were significantly associated with mortality. In particular, confusion and hyponatremia were associated with a sevenfold increase in mortality risk. There was no evidence that diabetes, stones, obstructive uropathy, AKI or proteinuria was associated with higher mortality. Nevertheless, 143 of the total 1146 patients died (12.5%). While 26% of the patients who had upfront emergency nephrectomy died, only 9.7% and 10% of patients with medical management and medical management plus minimally invasive treatments died. However, patients that failed medical and minimally invasive treatments and needed salvage emergency nephrectomy had a mortality of upwards of 27%.
CONCLUSION
The risk factors for mortality in emphysematous pyelonephritis are shock, thrombocytopenia, confusion, hyponatremia and emergency nephrectomy. Conservative and minimally invasive treatment should be the initial management strategy for emphysematous pyelonephritis as they carry lesser mortality risks. The presence of risk factors may help predict the subset of patients who need aggressive treatment and minimally invasive treatment modalities or early nephrectomy.

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.

Meta-Analysis Review
BACKGROUND
Globally, antimicrobial resistance (AMR) restricted the armamentarium of the health care providers against infectious diseases, mainly due to the emergence of multidrug resistant. This review is aimed at providing contemporary bacterial profile and antimicrobial resistance pattern among pregnant women with significant bacteriuria.
METHODS
Electronic biomedical databases and indexing services such as PubMed/MEDLINE, Web of Science, EMBASE and Google Scholar were searched. Original records of research articles, available online from 2008 to 2021, addressing the prevalence of significant bacteriuria and AMR pattern among pregnant women and written in English were identified and screened. The relevant data were extracted from included studies using a format prepared in Microsoft Excel and exported to STATA 14.0 software for the outcome measure analyses and subgrouping.
RESULTS
The data of 5894 urine samples from 20 included studies conducted in 8 regions of the country were pooled. The overall pooled estimate of bacteriuria was 15% (95% CI 13-17%, I = 77.94%, p < 0.001) with substantial heterogeneity. The pooled estimate of Escherichia coli recovered from isolates of 896 urine samples was 41% (95% CI 38-45%) followed by coagulase-negative Staphylococci, 22% (95% CI 18-26%), Staphylococcus aureus, 15% (95% CI 12-18%), Staphylococcus saprophytic, 12% (95% CI 6-18%) Proteus mirabilis, 7% (95% CI 4-10%), Enterococcus species, 6% (0-12%), Pseudomonas aeruginosa, 4% (2-6%), Citrobacter species, 4% (95% CI 2-4%), Group B streptococcus, 3% (1-5%), and Enterobacter species, 2% (1-4%). Multidrug resistance proportions of E. coli, Klebsiella species, Staphylococcus aureus and Coagulase negative staphylococci, 83% (95% CI 76-91%), 78% (95% CI 66-90%), 89% (95% CI 83-96%), and 78% (95% CI 67-88%), respectively.
CONCLUSION
The result of current review revealed the occurrence of substantial bacteriuria among pregnant women in Ethiopia. Resistance among common bacteria (E. coli, Klebsiella species, Staphylococci species) causing UTIs in pregnant women is widespread to commonly used antibiotics. The high rate of drug resistance in turn warrants the need for regular epidemiological surveillance of antibiotic resistance and implementation of an efficient infection control and stewardship program.

BACKGROUND
A culture of improvement is an important feature of high-quality health care systems. However, health care teams often need support to translate quality improvement (QI) activities into practice. One method of support is consultation from a QI coach. The literature suggests that coaching interventions have a positive impact on clinical outcomes. However, the impact of coaching on specific process outcomes, like adoption of clinical care activities, is unknown. Identifying the process outcomes for which QI coaching is most effective could provide specific guidance on when to employ this strategy.
METHODS
We searched multiple databases from inception through July 2021. Studies that addressed the effects of QI coaching on process of care outcomes were included. Two reviewers independently extracted study characteristics and assessed risk of bias. Certainty of evidence was assessed using GRADE.
RESULTS
We identified 1983 articles, of which 23 cluster-randomized trials met eligibility criteria. All but two took place in a primary care setting. Overall, interventions typically targeted multiple simultaneous processes of care activities. We found that coaching probably has a beneficial effect on composite process of care outcomes (n = 9) and ordering of labs and vital signs (n = 6), and possibly has a beneficial effect on changes in organizational process of care (n = 5), appropriate documentation (n = 5), and delivery of appropriate counseling (n = 3). We did not perform meta-analyses because of conceptual heterogeneity around intervention design and outcomes; rather, we synthesized the data narratively. Due to imprecision, inconsistency, and high risk of bias of the included studies, we judged the certainty of these results as low or very low.
CONCLUSION
QI coaching interventions may affect certain processes of care activities such as ordering of labs and vital signs. Future research that advances the identification of when QI coaching is most beneficial for health care teams seeking to implement improvement processes in pursuit of high-quality care will support efficient use of QI resources.

Review
BACKGROUND
Morganella morganii is a Gram-negative, rod-shaped, facultative anaerobic bacillus divided into two subspecies, morganii and sibonii. Previously classified as Proteus morganii, it belongs to human gut commensal microbiota. Nevertheless, on rare occasions, especially in nosocomial and postoperative environment as well as in patients with the impaired immune system and young children, it may cause potentially fatal systemic infection.
OBJECTIVES
The aim of our systematic review was to determine whether and what invasive infections in humans were caused by Morganella morganii and to estimate outcomes of administered antibiotic management.
DATA SOURCES
This systematic review was registered at the PROSPERO database of systematic reviews and meta-analyses before initiation of the research (registration number CRD42020171919). Study eligibility criteria and participants. patients of any age and both sex harbouring Morganella morganii as the only microorganism in bodily fluids or tissues, from where it was isolated and identified by one or more of the following diagnostic methods: conventional techniques including colony morphology, Vitek 2, API or BD Phoenix biochemical systems, as well as more sophisticated methods, such as Matrix-assisted laser desorption ionization-time-of-flight mass spectrometry (MALDI-TOF MS) and species-specific PCR for M. morganii.
METHODS AND INTERVENTIONS
We have systematically searched MEDLINE, EBSCO, SCOPUS, SCINDEX and GOOGLE SCHOLAR for case reports and case series with M. morganii invasive infections.
RESULTS
M. morganii can cause serious infections of different tissue in patients of any age. The most isolates were susceptible to ceftazidime, imipenem and amikacin. Majority of the patients completely recovered after antibiotic treatment. About 15% of the patients died despite of the therapy. Gentamicin was the most frequently used antibiotic in the treatment of infection caused by M. morganii.
CONCLUSION
M. morganii invasive infections should be taken into consideration by the clinicians, especially in hospital conditions, due to its high degree of mortality and high potential of this bacterium to develop multidrug resistance. Treatment of M. morganii infections should include gentamycin in combination with third generation cephalosporin or another antibiotic to which M. morganii is susceptible (after testing isolates for third cephalosporin generation for the production of AmpC β -lactamases).

The prevalence of financial medication assistance (FMA), including patient assistance programs, coupons/copayment cards, vouchers, discount cards, and programs/pharmacy services that help patients apply for such programs, has increased. The impact of FMA on medication adherence and persistence has not been synthesized. The primary objective of this study was to review published studies evaluating the impact of FMA on the three phases of medication adherence (initiation [or primary adherence], implementation [or secondary adherence], and discontinuation) and persistence. Among these studies, the secondary objective was to report the impact of FMA on patient out-of-pocket costs and clinical outcomes. A systematic review was performed using MEDLINE and Web of Science. Of 656 articles identified, eight studies met all inclusion criteria. Seven studies examined FMA for medications treating cardiovascular diseases, while one study assessed FMA for cancer medications. Among included studies, FMA had a positive impact on medication adherence or persistence, and most measured this impact over one year or less. Of the three phases of medication adherence, implementation (5 of 8) was most commonly reported, followed by discontinuation (3 of 8), and then initiation (1 of 8). Regarding implementation, users of FMA had a higher mean medication possession ratio (MPR) than nonusers, ranging from 7 to 18 percentage points higher. The percentage of patients who discontinued medication was 7 percentage points lower in users of FMA versus nonusers for cardiovascular disease states. In one cancer study, FMA had a larger impact on initiation than discontinuation, ie, compared to nonusers, users of FMA were less likely to abandon an initial prescription (risk ratio= 0.12, 95% confidence interval [CI]: 0.08-0.18), and this effect was larger than the decreased likelihood of discontinuing the medication (hazard ratio = 0.76, 95% CI: 0.66-0.88). In 3 of 8 studies reporting on medication persistence, FMA increased the odds of medication persistence for one year ranged from 11% to 47%, depending on the study. In addition to adherence, half of the studies reported on FMA impacts on patient out-of-pocket costs and 3 of 8 studies reported on clinical outcomes. Impacts on patient out-of-pocket costs were mixed; two studies reported that out-of-pocket costs were higher for users of a coupon or a voucher versus nonusers, one study reported the opposite, and one study reported null effects. Impacts on clinical outcomes were either positive or null. We found that FMA has positive impacts on all phases of medication adherence as well as medication persistence over one year. Future studies should assess whether FMA has differential impacts based on phase of medication adherence and report on its longer-term (ie, beyond one year) impacts on medication adherence.

Based on the study and research on the pathogenesis of colorectal cancer, the types and functions of gut microbiota, and its role in guiding and regulating the occurrence and development of diseases, we have explored the mechanism of traditional Chinese medicine in the treatment of colorectal cancer by regulating the gut microbiota. Genetic variation, abnormal responses of innate and adaptive immunity, mucosal barrier dysfunction, imbalance of intestinal microbial colonization, personal and environmental risk factors are the main pathogenesis of colorectal cancer. The gut microbiota mainly includes (including , , and ) and (including and ), which have biological antagonism, nutrition for the organism, metabolic abilities, immune stimulation, and ability to shape cancer genes functions to body. The gut microbiota can be related to the health of the host. Current studies have shown that Chinese herbal compound, single medicinal materials, and monomer components can treat colorectal cancer by regulating the gut microbiota, such as Xiaoyaosan can increase the abundance of , , and and decrease the abundance of and . Therefore, studying the regulation and mechanism of gut microbiota on colorectal cancer is of great benefit to disease treatment.

Review
BACKGROUND
Antibiotic resistance (ABR) restricts the armamentarium of health-care providers against infectious diseases due to the emergence of multidrug resistance (MDR), especially in Gram-negative bacteria. This study aimed to determine pooled estimates of Gram-negative bacteria, their resistance profiles, and rates of MDR in patients with wound infection in Ethiopia.
METHODS
Electronic databases such as PubMed/MEDLINE, EMBASE, Science Direct, Web of Science, and Google Scholar were searched. Original articles, available online from 1988 to 2020, addressing the prevalence and resistance patterns of Gram-negative bacteria in patients with wound infection and written in English were screened. The data were extracted using a format prepared in Microsoft Excel and exported to STATA 14.0 for the outcome analyses.
RESULTS
The data of 15,647 wound samples, from 36 studies conducted in 5 regions of the country, were pooled. The overall pooled estimate of Gram-negative bacteria was 59% [95% CI: 52-65%, I = 96.41%, p < 0.001]. The pooled estimate of recovered from isolates of 5205 wound samples was 17% [95% CI: 14-20%], followed by , 11% [95% CI: 9-14%], , 11% [95% CI: 9-13%], , 8% [95% CI: 6-10%], Acinetobacter species, 4% [95% CI: 2-6%], Enterobacter species, 4% [95% CI: 3-5%], and Citrobacter species, 3% [95% CI: 2-4%]. Multidrug resistance prevalence estimates of , . , Citrobacter species, Enterobacter species and Acinetobacter species were 76% [95% CI: 66-86%], 84% [95% CI: 78-91%], 66% [95% CI:43-88%], 83% [95% CI:75-91%], 87% [95% CI:78-96%], 68% [95% CI:50-87%] and 71% [95% CI:46-96%], respectively.
CONCLUSION
There was high resistance in Gram-negative bacteria from wound specimens to commonly used antibiotics in Ethiopia. The data warrant the need of regular epidemiological surveillance of antimicrobial resistance and implementation of an efficient infection control program.

Review
BACKGROUND
Compared to men, women have lower treatment rates for cardiovascular disease (CVD), are at higher risk for medication non-adherence and have different reasons for being non-adherent. The aim of this study was to synthesize and evaluate gender-specific adherence-promoting interventions for cardiovascular medication and gender-specific effects of gender-neutral interventions.
METHODS
A systematic literature search was performed in PubMed, Embase, PsycINFO, CINAHL and Cochrane Library from January 2007 to October 2019. Intervention studies (with control group) aimed at improving cardiovascular medication adherence with minimally 14 weeks follow-up were included. Two reviewers independently screened titles and abstracts. Full text was obtained for selected abstracts and screened for final inclusion. Data extraction included gender-specific targeting or analysis.
RESULTS
The search identified 6502 citations. After screening title and abstract, full text was obtained from 127 potentially eligible articles. Ultimately, 11 articles were included that analyzed gender differences in gender-neutral interventions. Two reported a gender-specific intervention effect. Using an electronic reminder device, one study increased statin adherence in women. The other found a larger increase in adherence to CVD medication following telephone counseling for men than women. Nine studies did not identify a gender-specific effect.
CONCLUSION
Despite differences in levels of and reasons for non-adherence, most studies addressing adherence did not analyze potential differences in effect by gender. Moreover, none of the identified studies used gender-specific adherence promoting interventions. Increasing awareness about gender differences in adherence might lead to better tailoring of interventions to gender-specific needs and better results in improving adherence.

Review
spp. are members of the Enterobacteriaceae family and are Gram-negative, rod-shaped bacteria known to mainly cause urinary tract infections (UTIs) in humans. However, even though scarce evidence exists suggesting their potential to cause infective endocarditis (IE), a study summarizing the existing evidence is lacking. The purpose of this study was to systemically review all published cases of IE by species in the literature. A systematic review of PubMed, Scopus and Cochrane Library (through 5 May 2020) for studies providing epidemiological, clinical and microbiological data as well as data on treatment and outcomes of IE by species was performed. A total of 16 studies, containing data of 16 patients, were included. A prosthetic valve was present in 25%, while the most common causative pathogen was . Aortic valve was the most common infected site in 33.3%, followed by mitral valve in 26.7%. Diagnosis was set with transesophageal echocardiography in 37.5%, and transthoracic echocardiography in 25%, while the diagnosis was set at autopsy in 25%. Fever and sepsis were present in 100% and 84.6%, respectively. Aminoglycosides and cephalosporins were the most common antimicrobials used for treatment. Clinical cure was noted in 62.5%, while overall mortality was 43.8%. This systematic review describes IE by species in detail and provides information on epidemiology, clinical presentation, treatment and outcomes.
