Meta-Analysis Review
OBJECTIVES
We performed a systematic review and meta-analysis for the prevalence and risk factors of rheumatoid arthritis-related bronchiectasis (RA-BR).
METHODS
We queried PubMed and EMBASE databases to identify published literature related to prevalence and risk factors for RA-BR among patients with RA. Data extraction included study design, country, year, method of RA-BR detection, RA characteristics, numerator of RA-BR cases and denominator of patients with RA, and associations with RA-BR presence. We performed a meta-analysis using random or fixed effects models to estimate the prevalence of RA-BR among RA.
RESULTS
Out of a total of 253 studies, we identified 41 total studies that reported on prevalence (n = 34), risk factors (n = 5), or both (n = 2). The included studies had heterogeneous methods to identify RA-BR. Among the 36 studies reporting prevalence, 608 RA-BR cases were identified from a total of 8569 patients with RA. In the meta-analysis, the pooled overall prevalence of RA-BR among RA was 18.7% (95%CI 13.7-24.3%) using random effects and 3.8% (95%CI 3.3-4.2%) using fixed effects. Among studies that used high-resolution chest computed tomography (HRCT) imaging, the prevalence of RA-BR was 22.6% (95%CI 16.8-29.0%) using random effects. When only considering retrospective studies (n = 12), the pooled prevalence of RA-BR among RA was 15.5% (95%CI 7.5-25.5%); among prospective studies (n = 24), the pooled prevalence was 20.7% (95% CI 14.7-27.4%). Risk factors for RA-BR included older age, longer RA duration, genetics (CFTR and HLA), and undetectable circulating mannose binding lectin (MBL) as a biomarker.
CONCLUSION
In this systematic review and meta-analysis, the prevalence of RA-BR was nearly 20% among studies with HRCT imaging, suggesting that bronchiectasis may be a common extra-articular feature of RA. Relatively few factors have been associated with RA-BR. Future studies should standardize methods to identify RA-BR cases and investigate the natural history and clinical course given the relatively high prevalence among RA.

BACKGROUND
Traumatic diaphragmatic hernia (TDH) is rare in children, most often occurring following blunt thoracoabdominal trauma from high energy mechanisms, such as motor vehicle collisions (MVC). We performed a systematic review to describe injury details and management.
METHODS
Following PRISMA guidelines, a systematic literature search was performed to identify publications of blunt TDH in patients < 18 y old. Conflicts were resolved by consensus. Data were collected on demographics, TDH location, mechanism of injury, associated intraabdominal injuries (IAI), management, and outcomes. Denominators vary depending on number of patients with such information reported.
RESULTS
Fifty-eight articles were reviewed with 142 patients with TDH. The median age was seven y (range 0.25-16). Most were left-sided (85 of 126, 67.5%). MVC was the most common mechanism (66 of 142, 46.5%). IAI was present in 50.0% (57 of 114), most commonly liver injuries (25 of 57, 43.9%). Delayed diagnoses occurred in 49.6% (57 of 115, range 8 h-10 y), and were more common with right-sided TDH (76.0% versus 48.5%, P = 0.02). Chest radiography was 59.0% sensitive for TDH, while computed tomography sensitivity was 65.8%. Operative repair was performed on all surviving patients, and all underwent primary diaphragm repair. The overall mortality was 11.3% (n = 16), with four attributable to the TDH. There were no reported recurrences over a median follow-up of 12 mo.
CONCLUSIONS
Pediatric TDH is a rare diagnosis with a high rate of associated IAI and delayed diagnosis. Primary diaphragm repair was performed in all cases. Surgeons should maintain a high suspicion for diaphragm injury in blunt thoracoabdominal trauma.

Meta-Analysis Review
OBJECTIVES
We conducted a systematic review of the literature with meta-analysis to determine whether painful diabetic neuropathy is associated with a specific inflammatory profile.
METHODS
The study is based on the PRISMA statement for systematic reviews. We performed a search of published studies up until January 2021 in MEDLINE and Web of Science based on heading and free text terms. The search strategy included the phrases: diabetic peripheral neuropathy, painful peripheral neuropathy individually and in combination with the terms: inflammation and inflammatory biomarkers. We screened titles and abstracts and performed data extraction. We also manually searched the article titles in the reference lists of key studies and reviews published in the last 20 years.
DATA EXTRACTION
Data extracted from the studies included study design, inclusion and exclusion criteria, sample type including serum and plasma, source of the sample including patients with peripheral diabetic neuropathy or patients with painful and painless neuropathy of any etiology. Blood concentrations of all measured cytokines were recorded. Whenever possible we calculated the effect size and confidence interval. Non-human studies were excluded from the meta-analysis.
RESULTS
Thirteen studies were included in this meta-analysis. The study design was cross-sectional, case control or cohort type studies. Specific inflammatory mediators are significantly higher in painful than in painless diabetic neuropathy as well as in painful neuropathies of any etiology. Markers of inflammation are also increased in those patients with diabetes mellitus, who suffer from peripheral neuropathy in comparison to patients with diabetes mellitus but no signs of peripheral neuropathy. A proinflammatory state may be the common denominator of pain and peripheral neuropathy in patients with diabetes mellitus but the inflammatory profiles seem to differ.

Vaccine-Preventable Disease Incidence Based on Clinically, Radiologically, and Etiologically Confirmed Outcomes: Systematic Literature Review and Re-analysis of Pneumococcal Conjugate Vaccine Efficacy Trials.
BACKGROUND
Vaccine regulatory decision making is based on vaccine efficacy against etiologically confirmed outcomes, which may underestimate the preventable disease burden. To quantify this underestimation, we compared vaccine-preventable disease incidence (VPDI) of clinically defined outcomes with radiologically/etiologically confirmed outcomes.
METHODS
We performed a systematic review of efficacy trials for several vaccines (1997-2019) and report results for pneumococcal conjugate vaccines. Data were extracted for outcomes within a clinical syndrome, organized from most sensitive to most specific. VPDI was determined for each outcome, and VPDI ratios were calculated, with a clinically defined outcome (numerator) and a radiologically/etiologically confirmed outcome (denominator).
RESULTS
Among 9 studies, we calculated 27 VPDI ratios; 24 had a value >1. Among children, VPDI ratios for clinically defined versus vaccine serotype otitis media were 0.6 (95% CI not calculable), 2.1 (1.5-3.0), and 3.7 (1.0-10.2); the VPDI ratios comparing clinically defined with radiologically confirmed pneumonia ranged from not calculable to 2.7 (1.2-10.4); the VPDI ratio comparing clinically suspected invasive pneumococcal disease (IPD) with laboratory-confirmed IPD was 3.8 (95% CI not calculable). Among adults, the ratio comparing clinically defined with radiologically confirmed pneumonia was 1.9 (-6.0 to 9.1) and with vaccine serotype-confirmed pneumonia was 2.9 (.5-7.8).
CONCLUSIONS
While there is substantial uncertainty around individual point estimates, there is a consistent trend in VPDI ratios, most commonly showing under-ascertainment of 1.5- to 4-fold, indicating that use of clinically defined outcomes is likely to provide a more accurate estimate of a pneumococcal conjugate vaccine's public health value.

Review
INTRODUCTION
The HIV care cascade examines the attrition of people living with HIV from diagnosis to the use of antiretroviral therapy (ART) and suppression of viral replication. We reviewed the literature from sub-Saharan Africa to assess the definitions used for the different steps in the HIV care cascade.
METHODS
We searched PubMed, Embase and CINAHL for articles published from January 2004 to December 2020. Longitudinal and cross-sectional studies were included if they reported on at least one step of the UNAIDS 90-90-90 cascade or two steps of an extended 7-step cascade. A step was clearly defined if authors reported definitions for numerator and denominator, including the description of the eligible population and methods of assessment or measurement. The review protocol has been published and registered in Prospero.
RESULTS AND DISCUSSION
Overall, 3364 articles were screened, and 82 studies from 19 countries met the inclusion criteria. Most studies were from Southern (38 studies, 34 from South Africa) and East Africa (29 studies). Fifty-eight studies (71.6%) were longitudinal, with a median follow-up of three years. The medium number of steps covered out of 7 steps was 3 (interquartile range [IQR] 2 to 4); the median year of publication was 2015 (IQR 2013 to 2019). The number of different definitions for the numerators ranged from four definitions (for step "People living with HIV") to 21 (step "Viral suppression"). For the denominators, it ranged from three definitions ("Diagnosed and aware of HIV status") to 14 ("Viral suppression"). Only 12 studies assessed all three of the 90-90-90 steps. Most studies used longitudinal data, but denominator-denominator or denominator-numerator linkages over several steps were rare. Also, cascade data are lacking for many countries. Our review covers the academic literature but did not consider other data, such as government reports on the HIV care cascade. Also, it did not examine disengagement and reengagement in care.
CONCLUSIONS
The proportions of patients retained at each step of the HIV care cascade cannot be compared between studies, countries and time periods, nor meta-analysed, due to the many different definitions used for numerators and denominators. There is a need for standardization of methods and definitions.

To meet the WHO vision of reducing medication errors by 50%, it is essential to know the current error rate. We undertook an integrative review of the literature, using a systematic search strategy. We included studies that provided an estimate of error rate (i.e. both numerator and denominator data), regardless of type of study (e.g. RCT or observational study). Under each method type, we categorised the error rate by type, by classification used by the primary studies (e.g. wrong drug, wrong dose, wrong time), and then pooled numerator and denominator data across studies to obtain an aggregate error rate for each method type. We included a total of 30 studies in this review. Of these, two studies were national audit projects containing relevant data, and for 28 studies we identified five discrete method types: retrospective recall (6), self-reporting (7), observational (5), large databases (7), and observing for drug calculation errors (3). Of these 28 studies we included 22 for a numerical analysis and used six to inform a narrative review. Drug error is recalled by ~1 in 5 anaesthetists as something that happened over their career; in self-reports there is an admitted rate of ~1 in 200 anaesthetics. In observed practice, error is seen in almost every anaesthetic. In large databases, drug error constitutes ~10% of anaesthesia incidents reported. Wrong drug or dose form the most common type of error across all five study method types (especially dosing error in paediatric studies). We conclude that medication error is common in anaesthetic practice, although we were uncertain of the precise frequency or extent of harm. Studies concerning medication error are very heterogenous, and we recommend consideration of standardised reporting as in other research domains.

Meta-Analysis
BACKGROUND
This study systematically reviewed the literature regarding perioperative mortality in human adults undergoing elective surgical abdominal wall hernia repair, including an audit of the Royal Australasian College of Surgeons (RACS) Australian and New Zealand Audit of Surgical Mortality (ANZASM) database.
METHODS
A systematic review was conducted in accordance with PRISMA guidelines for the reporting of systematic reviews and meta-analysis of observational studies. Cochrane Library, PubMed, MEDLINE and Embase database searches and data extraction were conducted from June 1979 to October 2019. Statistical analysis was undertaken utilising denominator values for elective hernia procedures derived from the Australian Institute of Health and Welfare (AIHW) data. Risk-adjusted perioperative mortality rates for the relevant procedures were also produced, using a binary logistic regression for the risk adjustment.
RESULTS
Through systematic review of the literature, it was established that the overall reported perioperative mortality in human adults undergoing elective surgical abdominal wall hernia repair was low (0.1%-0.5%). Using ANZASM and AIHW data, the calculated risk-adjusted mortality rate for Australian patients was found to be significantly lower (0.04%-0.06%, p < 0.001).
CONCLUSION
The risk-adjusted mortality rate for elective abdominal wall hernia surgery in Australia is very low and compares favourably to international cohorts. Despite low absolute numbers, the factors which were most significantly associated with increased perioperative mortality in patients undergoing elective surgical abdominal wall hernia repair were increased age, cardiorespiratory co-morbidity and incisional hernia repair.

BACKGROUND
The burden of stroke is increasing in India; stroke is now the fourth leading cause of death and the fifth leading cause of disability. Previous research suggests that the incidence of stroke in India ranges between 105 and 152/100,000 people per year. However, there is a paucity of available data and a lack of uniform methods across published studies.
AIM
To identify high-quality prospective studies reporting the epidemiology of stroke in India.
SUMMARY OF REVIEW
A search strategy was modified from the Cochrane Stroke Strategy and adapted for a range of bibliographic databases from January 1997 to August 2020. From 7717 identified records, nine studies were selected for inclusion; three population-based registries, a further three population-based registries also using community-based ascertainment and three community-based door-to-door surveys. Studies represented the four cities of Mumbai, Trivandrum, Ludhiana, Kolkata, the state of Punjab, and 12 villages of Baruipur in the state of West Bengal. The total population denominator was 22,479,509 and 11,654 (mean 1294 SD 1710) people were identified with incident stroke. Crude incidence of stroke ranged from 108 to 172/100,000 people per year, crude prevalence from 26 to 757/100,000 people per year, and one-month case fatality rates from 18% to 42%.
CONCLUSIONS
Further high-quality evidence is needed across India to guide stroke policy and inform the development and organization of stroke services. Future researchers should consider the World Health Organization STEPwise approach to Surveillance framework, including longitudinal data collection, the inclusion of census population data, and a combination of hospital-registry and comprehensive community ascertainment strategies to ensure complete stroke identification.

Review
BACKGROUND
Patient-reported outcome measures are measures of patients' health-related quality of life. They should be added to other lymphedema measurements. With an improved disease-free survival of secondary lower limb lymphedema, attention must focus on such assessments.
OBJECTIVE
The objectives of this study were to locate and critically appraise suitable patient-reported outcomes measures for lower limb lymphedemas and search for existing valid translations for native German speakers.
METHODS
A systematic literature research was conducted. 20 semantical categories for qualitative analysis were evolved. Six questionnaires available in English and some in validated translations remained for analysis.
RESULTS
Lower limb lymphedema patients experience poor quality of life, and one of the most critical denominators is skin quality. To establish skin care and prevent cellulitis, patients must learn about skin problems. Only two tools asked for past infections. This is considered crucial because of knowledge building and prophylactic behavior. Questions on movement restrictions were available in one questionnaire. As these have a close connection to one's ability to perform activities of daily life, they can affect quality of life. Afflicted patients have problems with the choice and availability of clothing. Only three questionnaires asked questions about clothing or shoes. Lymphedema patients are exposed to more psychological stress than healthy subjects, but only three questionnaires covered questions about this burden. There was a lack of reporting on psychometric data (Cronbach's alpha, intraclass correlation), which hinders the external validity. Analyzed questionnaires were available in English but only one in German.
CONCLUSIONS
The analyzed questionnaires were in English, and only one was adapted and tested for native German speakers. For clinical practice, Devoogdt's questionnaire is recommended despite some shortcomings. There is a need for validated lymphedema questionnaires in German.

Review
BACKGROUND
Healthcare-associated infections (HAI) are important causes of neonatal morbidity and mortality in developing countries. We reviewed the incidence and the pathogens involved in HAI among infants admitted to neonatal intensive care units (NICU) in Brazil.
METHODS
A search was conducted in the MEDLINE, LILACS and SciELO databases from January 1995 to October 2019. Two authors scrutinized potential articles independently, after one author selected them from screening abstracts from every article flagged as related to neonatal HAI. Then, they were included in the review if they met our inclusion criteria. The studies were evaluated based on a quality score proposed by the authors, rated 0 to 1, with 1 point as the best quality rate. Pooled estimates and 95% confidence intervals (95% CI) for HAI cumulative incidence and incidence density were calculated, when the same denominators were available, using meta-analysis. A quality effect was applied to the models using the MetaXL software. Heterogeneity was assessed using I statistics and the Cochran's Q test.
RESULTS
Of a total of 5596 citations identified, 15 studies met the inclusion criteria for this review, which comprised 24,408 patients and 312,744 patient-days. Quality of the studies varied between 0.36 and 1 according to the adopted score, and six (40.0%) studies presented a score of 1. Pooled HAI incidence was 36.1 (95% CI 22.8-50.7) infections and 26.3 (95% CI 18.4-35.0) infected patients per 100 patients. Pooled HAI incidence density was 23.5 (95% CI 16.3-33.9) per 1000 patient-days. Pooled incidence density rates of bloodstream infection and ventilator-associated pneumonia were 13.1 per 1000 catheter-days (95% CI 4.3-40.1) and 7.9 per 1000 ventilator-days (95% CI 1.1-55.5), respectively. A high degree of heterogeneity was observed in all models (I > 98% and Cochran's Q test with p < 0.05). Coagulase-negative Staphylococci (32.1%), Staphylococcus aureus (13.8%) and Klebsiella spp. (12.4%) were the most prevalent causative bacterial pathogens.
CONCLUSIONS
The findings show high incidence of neonatal HAI in Brazilian NICU; therefore, efforts to standardize the collection and notification of HAI are needed in order to strengthen surveillance in the country and implement preventive measures, routine assessment, and close monitoring of neonates.
