RESUMO
BACKGROUND: Many women eligible for breast conservation therapy (BCT) elect unilateral mastectomy (UM) with or without contralateral prophylactic mastectomy (CPM) and cite a desire for "peace of mind." This study aimed to characterize how peace of mind is defined and measured and how it relates to surgical choice. METHODS: Nine databases were searched for relevant articles through 8 October 2023, and data were extracted from articles meeting the inclusion criteria. RESULTS: The inclusion criteria were met by 20 studies. Most were prospective cohort studies (65%, 13/20). In the majority of the studies (72%, 13/18), Non-Hispanic white/Caucasian women comprised 80 % or more of the study's sample. Almost half of the studies used the phrase "peace of mind" in their publication (45%, 9/20), and few directly defined the construct (15%, 3/20). Instead, words representing an absence of peace of mind were common, specifically, "anxiety" (85%, 17/20), "fear" (75%, 15/20), and "concern" (75%, 15/20). Most of the studies (90%, 18/20) measured peace of mind indirectly using questionnaires validated for anxiety, fear, worry, distress, or concern, which were administered at multiple postoperative time points (55%, 11/20). Most of the studies (95%, 18/19) reported at least one statistically significant result showing no difference in peace of mind between BCT, UM, and/or CPM at their latest time of assessment. CONCLUSION: Peace of mind is largely framed around concepts that suggest its absence, namely, anxiety, fear, and concern. Existing literature suggests that peace of mind does not differ among average-risk women undergoing BCT, UM, or CPM. Shared surgical decisions should emphasize at least comparable emotional and/or psychosocial well-being between CPM and breast conservation.

BACKGROUND AND AIMS: Substantial differences exist in pancreatic cancer outcomes across ethnoracial stratifications. We sought to assess racial, ethnic, sex, and age reporting and inclusion of participants in pancreatic cancer screening studies. METHODS: A systematic search of Cochrane Library, Ovid Embase, Google Scholar, Ovid MEDLINE, PubMed, Scopus, and Web of Science Core Collection from inception to 2022 was conducted. Original studies on pancreatic cancer screening were identified and assessed for reporting and inclusion on race, ethnicity, sex, and age. The pooled proportions of study participants for these characteristics were calculated and compared with population-based benchmarks. RESULTS: Among 27 eligible pancreatic cancer screening studies, 26 reported data on either sex, race, or ethnicity, with a total of 5273 participants. Information on participant sex was reported by 26, race by 12, and ethnicity by 8 studies. Participants in these studies were almost all white (pooled proportion, 93.1%; 95% confidence interval [CI], 89.7-96.4) and non-Latino (pooled proportion, 97.4%; 95% CI, 94.0-100), and these groups were over-represented when compared with the general population. Female participants were well represented, with a pooled proportion of 63.2% (95% CI, 59.9-66.6). When reported, mean or median participant age was <60 years. Meta-regression revealed higher proportions of female participants in studies from the United States (P = .002). No association between increasing participation of racial or ethnic under-represented populations and study quality, ascending year of publication, or source of study funding was noted. CONCLUSIONS: Substantial disparities in race, ethnicity, sex, and age reporting and inclusion in pancreatic cancer studies were noted, even among high-quality and publicly funded studies.

BACKGROUND & AIMS: Identification and resection of successful targets, that is, T1 N0M0 pancreatic ductal adenocarcinoma (PDAC) and high-grade precursors during surveillance of high-risk individuals (HRIs) confers improved survival. Late-stage PDACs refer to T2-4 N0M0 and nodal or distant metastatic PDAC stages diagnosed during the follow-up phase of HRI surveillance. This study aimed to quantify late-stage PDACs during HRI surveillance and identify associated clinicoradiologic factors. METHODS: A systematic search (PROSPERO:CRD42018117189) from Cochrane Library, Embase, Google Scholar, Medline, PubMed, Scopus, and Web of Science was last performed on April 18, 2021. Only original HRI surveillance manuscripts that specified follow-up strategies were included, and studies with only baseline information were excluded. Cumulative incidences of advanced neoplasia: high-grade precursors and all PDACs, and surveillance-detected/interval late-stage PDACs were calculated through random-effects model. Incidence of late-stage PDACs underwent metaregression to identify association with HRI clinicoradiologic features. Publication bias was assessed through the funnel plot and Egger's regression line. RESULTS: Thirteen original surveillance studies included 2169 HRIs followed over 7302.72 patient-years. Cumulative incidence of advanced neoplasia and late-stage PDACs was 3.3 (95% confidence interval [CI]: 0.6-7.4) and 1.7 (95% CI: 0.2-4.0) per 1000 patient-years, respectively. Late-stage PDACs lacked significant association with surveillance imaging, baseline pancreatic morphology, study location, genetic background, gender, or age. Limited information on diagnostic error, symptoms, timing of presentation, lesion site, and surveillance adherence precluded formal meta-analysis. CONCLUSION: A sizeable proportion of late-stage PDACs were detected during follow-up. Their incidence lacked association with baseline clinicoradiologic features. Further causal investigation of stage-based outcomes is warranted for overall improvement in HRI surveillance.

BACKGROUND & AIMS: Low-risk branch duct intraductal papillary mucinous neoplasms (BD-IPMNs) lacking worrisome features (WF) and high-risk stigmata (HRS) warrant surveillance. However, their optimal duration, especially among cysts with initial 5 years of size stability, warrants further investigation. We systematically reviewed the surveillance of low-risk BD-IPMNs and investigated the incidence of WF/HRS and advanced neoplasia, high-grade dysplasia, and pancreatic cancer during the initial (<5 years) and extended surveillance period (>5-years). METHODS: A systematic search (CRD42020117120) identified studies investigating long-term IPMN surveillance outcomes of low-risk IPMN among the Cochrane Library, Embase, Google Scholar, Ovid Medline, PubMed, Scopus, and Web of Science, from inception until July 9, 2021. The outcomes included the incidence of WF/HRS and advanced neoplasia, disease-specific mortality, and surveillance-related harm (expressed as percentage per patient-years). The meta-analysis relied on time-to-event plots and used a random-effects model. RESULTS: Forty-one eligible studies underwent systematic review, and 18 studies were meta-analyzed. The pooled incidence of WF/HRS among low-risk BD-IPMNs during initial and extended surveillance was 2.2% (95% CI, 1.0%-3.7%) and 2.9% (95% CI, 1.0%-5.7%) patient-years, respectively, whereas the incidence of advanced neoplasia was 0.6% (95% CI, 0.2%-1.00%) and 1.0% (95% CI, 0.6%-1.5%) patient-years, respectively. The pooled incidence of disease-specific mortality during initial and extended surveillance was 0.3% (95% CI, 0.1%-0.6%) and 0.6% (95% CI, 0.0%-1.6%) patient-years, respectively. Among BD-IPMNs with initial size stability, extended surveillance had a WF/HRS and advanced neoplasia incidence of 1.9% (95% CI, 1.2%-2.8%) and 0.2% (95% CI, 0.1%-0.5%) patient-years, respectively. CONCLUSIONS: A lower incidence of advanced neoplasia during extended surveillance among low-risk, stable-sized BD-IPMNs was a key finding of this study. However, the survival benefit of surveillance among this population warrants further exploration through high-quality studies before recommending surveillance cessation with certainty.

OBJECTIVES: We performed a systematic review and meta-analysis to estimate the effect of early active empirical antibiotics for MRSA on mortality, both in patients admitted with MRSA infections and in patients admitted with common infectious syndromes, for whom the causative pathogen may not have been MRSA. METHODS: A systematic literature search was conducted using Embase, MEDLINE, PubMed, Web of Science, Cochrane, Scopus and Google Scholar from the earliest entry through to 26 April 2022. We included studies of patients hospitalized with culture-proven MRSA infections that compared mortality rates depending on whether patients received active empirical antibiotics. The primary outcome was the adjusted OR for mortality with early active empirical antibiotics. After performing random-effects meta-analysis, we estimated the absolute risk reduction in mortality with initial empirical MRSA coverage for common infectious syndromes based on the prevalence of MRSA and baseline mortality rate for each syndrome, as reported in the medical literature. RESULTS: Of an initial 2136 unique manuscripts, 37 studies (11â661 participants) met our inclusion criteria. Fifteen studies (6066 participants) reported adjusted OR of mortality. The pooled adjusted OR for mortality was 0.64 (95% CI, 0.48-0.84), favouring active empirical antibiotics. The estimated absolute mortality benefit was 0% for patients with pneumonia, 0.1% (95% CI, 0.04-0.2) for non-critically ill patients with soft tissue infections, 0.04% (95% CI, 0.01-0.05) for non-critically ill patients with urinary tract infections, 0.6% (95% CI, 0.2-1.0) for patients with septic shock, and 1.0% (95% CI, 0.3-1.4) for patients with catheter-related infections admitted to ICUs. CONCLUSIONS: For the three most common infections in the hospital, the absolute benefit on mortality of empirical antibiotics against MRSA is 0.1% or less. Meaningful benefit of empirical antimicrobials against MRSA is limited to patients with approximately 30% mortality and 10% prevalence of MRSA. Avoiding empirical antibiotics against MRSA for low-risk infections would substantially reduce the use of anti-MRSA therapy.

BACKGROUND AND AIM: Idiopathic myointimal hyperplasia of the mesenteric veins (IMHMV) is an uncommon cause of colonic ischemia for which surgical treatment is typically curative. We describe clinical, radiologic, and endoscopic findings in IMHMV patients to provide clinicians with a framework for pre-surgical identification of this rare disease. METHODS: We performed a systematic review of seven databases for IMHMV cases and identified additional cases from Yale New Haven Hospital records. To identify features specifically associated with colonic ischemia due to IMHMV, we performed multivariate logistic regression analysis incorporating data from a large cohort of patients with biopsy-proven ischemic colitis. RESULTS: A total of 124 patients with IMHMV were identified (80% male, mean age 53 years, 56% Caucasian). Presenting symptoms were most commonly abdominal pain (86%) and diarrhea (68%). The most affected areas were the sigmoid colon (91%) and rectum (61%). Complications associated with diagnostic delay occurred in 29% of patients. Radiologic vascular abnormalities including non-opacification of the inferior mesenteric vein were observed in 35% of patients. Of the patients, 97% underwent curative surgical resection. Compared with non-IMHMV colonic ischemia, IMHMV was significantly associated with younger age, male sex, absence of rectal bleeding on presentation, rectal involvement, and mucosal ulcerations on endoscopy. CONCLUSION: IMHMV is a rare, underreported cause of colonic ischemia that predominantly involves the rectosigmoid. Our findings suggest younger age, rectal involvement, and absence of rectal bleeding as clinical features to help identify select patients presenting with colonic ischemia as having higher likelihood of IMHMV and therefore consideration of upfront surgical management.

BACKGROUND: Microangiopathic hemolytic anemia (MAHA) is a rare paraneoplastic syndrome that has been reported in patients with gastric signet ring cell carcinoma (SRCC). Clinical and prognostic features of MAHA in this setting have been poorly described. MATERIALS AND METHODS: We conducted a systematic review in 8 databases of gastric SRCC complicated by MAHA and performed a case-control study assessing factors associated with survival in patients with gastric SRCC and MAHA in our pooled cohort compared with age-, sex-, and stage-matched cases of gastric SRCC from the Surveillance, Epidemiology, and End Results (SEER) database. Descriptive analyses were performed and multivariable Cox-proportional hazards regression modeling was used to determine factors associated with overall survival. RESULTS: All identified patients (n = 47) were symptomatic at index presentation, commonly with back/bone pain, and dyspnea. Microangiopathic hemolytic anemia was the first manifestation of gastric SRCC in 94% of patients. Laboratory studies were notable for anemia (median 7.7 g/dL), thrombocytopenia (median 45.5 × 103/µL), and hyperbilirubinemia (median 2.3 mg/dL). All patients with MAHA had metastatic disease at presentation, most often to the bone, bone marrow, and lymph nodes. Median survival in patients with gastric SRCC and MAHA was significantly shorter than a matched SEER-derived cohort with metastatic gastric SRCC (7 weeks vs 28 weeks, P < .01). In multivariate analysis, patients with MAHA were at significantly increased risk of mortality (HR 3.28, 95% CI 2.11-5.12). CONCLUSION: Microangiopathic hemolytic anemia is a rare, late-stage complication of metastatic gastric SRCC and is associated with significantly decreased survival compared with metastatic gastric SRCC alone.

INTRODUCTION: The decision to shorten the duration of DAPT following PCI in patients with ACS remains controversial because of the concern for increased ischemic events. METHODS: We performed a comprehensive literature search in seven databases to explore the efficacy of 1 to 3 months of DAPT in patients who underwent PCI for ACS. Randomized controlled trials that compared 1 to 3 months with 6 to 12 months of DAPT after PCI for ACS were identified. Integrated hazard ratio (HR) and 95% confidence interval (CI) were calculated by random effects model for each prespecified outcome of interest. Meta-regression analyses were performed to examine the association of outcomes with select patient characteristics. RESULTS: A total of 9 randomized controlled trials consisting of 25,907 patients were included. There was no difference in the hazard of NACE (HR 0.92, 95% CI 0.79-1.07) and MACE (HR 0.96, 95% CI 0.78-1.17) between 1 and 3 months of DAPT and 6 to 12 months of DAPT. However, implementing 1 to 3 months of DAPT was associated with lower hazard of both any bleeding (HR 0.55, 95% CI 0.46-0.66) and major bleeding (HR 0.47, 95% CI 0.36-0.62). Meta-regression revealed a nonsignificant but increasing trend of both NACE and MACE with greater proportion of left main and left anterior descending coronary artery lesions and greater proportion of STEMI included in the trials. CONCLUSION: Our findings suggest that 1 to 3 months of DAPT has similar efficacy for preventing ischemic events with reduced bleeding risk compared with 6 to 12 months of DAPT.

BACKGROUND: Clinical guidelines recommend continuing antiplatelet monotherapy with aspirin and, in certain situations, other antiplatelet agents in patients undergoing endoscopic retrograde cholangiopancreatography (ERCP) with sphincterotomy. AIMS: Given the scant evidence supporting this recommendation, our primary objective was to determine if the risk of post-sphincterotomy bleeding was increased in patients on antiplatelet monotherapy. METHODS: We performed a systematic search of Cochrane Library, Ovid Embase, Ovid Medline, Pubmed, Scopus, and Web of Science Core Collection databases. Inclusion criteria were adult patients undergoing ERCP and sphincterotomy on antiplatelet monotherapy with the comparator of no antithrombotic therapy. Our primary outcome was post-sphincterotomy bleeding. Methodological quality was assessed with the ROBINS-I tool and the Newcastle-Ottawa Scale. Meta-analysis with random-effects model was performed. RESULTS: The search identified 4676 unique citations, with six cohort studies meeting our inclusion criteria. Post-sphincterotomy bleeding was increased in patients on antiplatelet monotherapy: OR = 1.53 (95% CI 1.03-2.28) without substantial heterogeneity (I2 = 0%). The number needed to harm (the number of patients who would have to receive antiplatelet monotherapy for one additional patient to have a post-sphincterotomy bleeding episode) was 185(95% CI 80-2272). All included studies had methodological shortcomings. CONCLUSION: Antiplatelet monotherapy was associated with a modestly increased risk of post-sphincterotomy bleeding in our systematic review and meta-analysis. More high-quality studies are needed to improve certainty regarding the estimated effect size. REGISTRATION: PROSPERO CRD42020153019.

BACKGROUND: Non-communicable diseases [NCDs] are leading causes of ill health among women of reproductive age and an increasingly important cause of maternal morbidity and mortality worldwide. Reliable data on NCDs is necessary for accurate measurement and response. However, inconsistent definitions of NCDs make reliable data collection challenging. We aimed to map the current global literature to understand how NCDs are defined, operationalized and discussed during pregnancy, childbirth and the postnatal period. METHODS: For this scoping review, we conducted a comprehensive global literature search for NCDs and maternal health covering the years 2000 to 2020 in eleven electronic databases, five regional WHO databases and an exhaustive grey literature search without language restrictions. We used a charting approach to synthesize and interpret the data. RESULTS: Only seven of the 172 included sources defined NCDs. NCDs are often defined as chronic but with varying temporality. There is a broad spectrum of conditions that is included under NCDs including pregnancy-specific conditions and infectious diseases. The most commonly included conditions are hypertension, diabetes, epilepsy, asthma, mental health conditions and malignancy. Most publications are from academic institutions in high-income countries [HICs] and focus on the pre-conception period and pregnancy. Publications from HICs discuss NCDs in the context of pre-conception care, medications, contraception, health disparities and quality of care. In contrast, publications focused on low- and middle-income countries discuss NCDs in the context of NCD prevention. They take a life cycle approach and advocate for integration of NCD and maternal health services. CONCLUSION: Standardising the definition and improving the articulation of care for NCDs in the maternal health setting would help to improve data collection and facilitate monitoring. It would inform the development of improved care for NCDs at the intersection with maternal health as well as through a woman's life course. Such an approach could lead to significant policy and programmatic changes with the potential corresponding impact on resource allocation.

BACKGROUND: Repurposing is a drug development strategy receiving heightened attention after the Food and Drug Administration granted emergency use authorization of several repurposed drugs to treat Covid-19. There remain knowledge gaps on the root causes, facilitators and barriers for repurposing. METHOD: This systematic review used controlled vocabulary and free text terms to search ABI/Informa, Academic Search Premier, Business Source Complete, Cochrane Library, EconLit, Google Scholar, Ovid Embase, Ovid Medline, Pubmed, Scopus, and Web of Science Core Collection databases for the characteristics, reasons and example of companies deprioritizing development of promising drugs and barriers, facilitators and examples of successful re-purposing. RESULTS: We identified 11,814 articles, screened 5,976 for relevance, found 437 eligible for full text review, 115 of which were included in full analysis. Most articles (66%, 76/115) discussed why promising drugs are abandoned, with lack of efficacy or superiority to other therapies (n = 59), strategic business reasons (n = 35), safety problems (n = 28), research design decisions (n = 12), the complex nature of a studied disease or drug (n = 7) and regulatory bodies requiring more information (n = 2) among top reasons. Key barriers to repurposing include inadequate resources (n = 42), trial data access and transparency around abandoned compounds (n = 20) and expertise (n = 11). Additional barriers include uncertainty about the value of repurposing (n = 13), liability risks (n = 5) and intellectual property (IP) challenges (n = 26). Facilitators include the ability to form multi-partner collaborations (n = 38), access to compound databases and database screening tools (n = 32), regulatory modifications (n = 5) and tax incentives (n = 2). CONCLUSION: Promising drugs are commonly shelved due to insufficient efficacy or superiority to alternate therapies, poor market prospects, and industry consolidation. Inadequate resources and data access and challenges negotiating IP are key barriers to repurposing reaching its full potential as a core approach in drug development. Multi-partner collaborations and the availability and use of compound databases and tax incentives are key facilitators for repurposing. More research is needed on the current value of repurposing in drug development and how to better facilitate resources to support it, where valuable, especially financial, staffing for out-licensing shelved products, and legal expertise to negotiate IP agreements in multi-partner collaborations. TRIAL REGISTRATION: The protocol was registered on Open Science Framework ( https://osf.io/f634k/ ) as it was not eligible for registration on PROSPERO as the review did not focus on a health-related outcome.

OBJECTIVE: The aim of this study was to describe genital hair thread tourniquet syndrome (HTTS) and its treatment by pediatric and adolescent health care providers through a systematic literature review. METHODS: We performed a systematic literature review on pediatric male and female genital HTTS. Studies were included if they involved genital HTTS in males or females 21 years and younger and were published in English. The main outcomes were body parts involved, symptoms, treatment, anesthetic type, providers involved in diagnosis and management, and implications of delayed or missed diagnosis. RESULTS: There were 38 female cases from 33 publications (1973-2020) and 147 male cases from 47 publications (1951-2019). The average age among females and males was 9.1 and 5.1 years, respectively. Among cases involving female patients, 93% of them were premenarchal; patients were circumcised in 90% of reviewed cases of male HTTS. The most commonly involved body parts were clitoris and labia minora in females, and penis and urethra in males. Males most commonly presented with edema and urinary symptoms, whereas females most commonly presented with edema and pain. General anesthesia was used for tourniquet excision in most cases. Male and female genital HTTS were mostly managed by urologists and emergency medicine physicians, respectively. CONCLUSION: This systematic literature review of more than 150 cases of male and female genital HTTS describes evaluation and management of genital HTTS spanning 7 decades. The main treatment of genital HTTS remains prompt diagnosis and removal of the tourniquet, as well as education on prevention strategies. Delayed diagnosis due to lack of recognition of the HTTS can lead to serious sequelae. Development of national guidelines regarding best practices in management of genital HTTS disseminated to all providers taking care of pediatric and adolescent patients will lead to improved patient care.

The profound transformation of medical libraries over the last twenty years reflects the advancements in medical education and health care delivery, increased expectations of users, and accelerated evolution of technology. The Harvey Cushing/John Hay Whitney Medical Library (CWML) used this opportunity to rethink how staffing could be redeployed to accommodate these new developments. After assessing processes, workflows, and individual responsibilities, library administration devised a novel team approach that would allow clerical & technical (C&T) staff to work across departmental lines to provide a broader variety of in-depth and frontline services. This paper will share how the C&T staff at the CWML developed a broader skill set, while providing library services to users in the rapidly changing field of medical education and health care services.

BACKGROUND AND AIMS: Common bile duct (CBD) dilation is a frequent indication for EUS. Among asymptomatic individuals, biliary dilation may not be clinically significant; however, EUS is often relied on for the exclusion of benign and malignant pathology that might require further intervention. The yield of EUS evaluation for this indication is not well characterized and has significant implications for health resource utilization because asymptomatic biliary dilation is prevalent. Through this systematic review, we sought to appraise the yield of EUS evaluation of asymptomatic patients with radiologic evidence of isolated CBD dilation. METHODS: A protocolled search (PROSPERO: CRD42020193428) extracted original studies from the Cochrane Library, Ovid Embase, Google Scholar, Ovid Medline, PubMed, Scopus, and Web of Science Core Collection that described diagnostic yield of EUS among asymptomatic patients with biliary dilation. Cumulative EUS diagnostic yield was calculated through meta-analysis of proportions using inverse variance methods and a random-effects model. RESULTS: Of 2616 studies, 8 delineated the EUS yield among 224 asymptomatic patients. The cumulative yield of EUS for any pathology was 11.2% (95% confidence interval [CI], 3.6%- 21.6%). The EUS yield for benign etiologies was 9.2% (95% CI, 1.1%-21.9%), of which choledocholithiasis comprised 3.4% (95% CI, 0%-11.2%) and malignant etiologies .5% (95% CI, 0%-3.4%) of cases. CONCLUSIONS: EUS in patients with asymptomatic CBD dilation does yield findings of choledocholithiasis and malignancy, albeit at low rates. A cost-effectiveness analysis is warranted to further guide clinical decision-making in this area.

OBJECTIVE: We sought to conduct a systematic review and network meta-analysis to examine the association between institutional transcatheter aortic valve replacement (TAVR) volume and all-cause mortality. BACKGROUND: Since inception in 2011, there has been an exponential increase in the number of TAVR centers across the world. Multiple studies have questioned if a relationship exists between institutional TAVR volume and patient outcomes. METHODS: We performed a systematic literature search for relevant articles using a combination of free text terms in the title/abstract related to volume, TAVR, and patient outcomes. Two reviewers independently screened all titles/abstracts for eligibility based on pre-specified criteria. All-cause mortality data was pooled from eligible studies and centers were categorized as low-(30-50 cases), intermediate-, or high-volume (75-130 cases) based on their annual TAVR volumes. RESULTS: Our search yielded an initial list of 11,153 citations, 120 full text studies were reviewed and 7 studies met all inclusion and exclusion criteria, yielding a total of 1,93,498 TAVRs. Categorized according to center's annual volume; 25,062 TAVRs were performed in low-, 77,093 in intermediate- and 91,343 in high-volume centers. Network meta-analysis showed a relative reduction in mortality rates of 37%, 23% and 19%, for high volume versus low volume centers, high volume versus intermediate volume centers and intermediate versus low volume centers, respectively. CONCLUSIONS: Existing research clearly shows an inverse relationship between annual TAVR procedural volume and all-cause mortality. We need to focus on development of strong referral networks and consolidation rather than expansion of existing TAVR centers to improve patient outcomes, while ensuring adequate access-to-care.

OBJECTIVE: This study aimed to conduct a systematic review of the current literature to determine estimates of vertical transmission of coronavirus disease 2019 based on early RNA detection of severe acute respiratory syndrome coronavirus 2 after birth from various neonatal or fetal sources and neonatal serology. DATA SOURCES: Eligible studies published until May 28, 2020, were retrieved from PubMed, EMBASE, medRxiv, and bioRxiv collection databases. STUDY ELIGIBILITY CRITERIA: This systematic review included cohort studies, case series, and case reports of pregnant women who received a coronavirus disease 2019 diagnosis using severe acute respiratory syndrome coronavirus 2 viral RNA test and had reported data regarding the testing of neonates or fetuses for severe acute respiratory syndrome coronavirus 2 immediately after birth and within 48 hours of birth. A total of 30 eligible case reports describing 43 tested neonates and 38 cohort or case series studies describing 936 tested neonates were included. STUDY APPRAISAL AND SYNTHESIS METHODS: The methodological quality of all included studies was evaluated by a modified version of the Newcastle-Ottawa scale. Quantitative synthesis was performed on cohort or case series studies according to the neonatal biological specimen site to reach pooled proportions of vertical transmission. RESULTS: Our quantitative synthesis revealed that of 936 neonates from mothers with coronavirus disease 2019, 27 neonates had a positive result for severe acute respiratory syndrome coronavirus 2 viral RNA test using nasopharyngeal swab, indicating a pooled proportion of 3.2% (95% confidence interval, 2.2-4.3) for vertical transmission. Of note, the pooled proportion of severe acute respiratory syndrome coronavirus 2 positivity in neonates by nasopharyngeal swab in studies from China was 2.0% (8/397), which was similar to the pooled proportion of 2.7% (14/517) in studies from outside of China. Severe acute respiratory syndrome coronavirus 2 viral RNA testing in neonatal cord blood was positive in 2.9% of samples (1/34), 7.7% of placenta samples (2/26), 0% of amniotic fluid (0/51), 0% of urine samples (0/17), and 9.7% of fecal or rectal swabs (3/31). Neonatal serology was positive in 3 of 82 samples (3.7%) (based on the presence of immunoglobulin M). CONCLUSION: Vertical transmission of severe acute respiratory syndrome coronavirus 2 is possible and seems to occur in a minority of cases of maternal coronavirus disease 2019 infection in the third trimester. The rates of infection are similar to those of other pathogens that cause congenital infections. However, given the paucity of early trimester data, no assessment can yet be made regarding the rates of vertical transmission in early pregnancy and potential risk for consequent fetal morbidity and mortality.

PURPOSE OF REVIEW: With the establishment of antiretroviral treatment (ART) programs in low- and middle-income countries, people with HIV (PWH) in Latin America and the Caribbean (LAC) are living longer, subsequently developing chronic non-communicable diseases (NCDs). Few studies focus on the impact of aging among older LAC PWH. This systematic review aims to fill this information gap and understand the burden of aging with HIV in LAC. We identified peer-reviewed literature published in English, Spanish, or Portuguese from several databases to assess currently available evidence on the burden of aging with HIV in LAC and selected six common NCDs found in older PWH (cardiovascular disease [CVD], bone and musculoskeletal [MSK] disorders, cancer, renal disease, neurocognitive impairment [NCI], and depression). RECENT FINDINGS: Of the 5942 publications reviewed, only 53 articles were found with populations 40 years and older or age-related findings (27 CVD, 13 NCI or depression, 6 MSK disorders, 4 renal disease, 3 cancer). Most (79%) publications were from Brazil with few longitudinal studies on aging with HIV. Prevalence of illnesses such as CVD, NCI, depression, or osteoporosis varied widely depending on the screening instrument utilized and geographic population surveyed. Age was a significant predictor of comorbidity in nearly all studies. Our results demonstrate the need for longitudinal studies and validated screening instruments appropriate for use among PWH in LAC. Understanding the mechanisms behind aging in HIV and the roles of sociocultural factors and genetic diversity specific to LAC is needed to appropriately manage chronic comorbidities as PWH age.

BACKGROUND: The number of preventable inpatient deaths in the USA is commonly estimated as between 44,000 and 98,000 deaths annually. Because many inpatient deaths are believed to be preventable, mortality rates are used for quality measures and reimbursement. We aimed to estimate the proportion of inpatient deaths that are preventable. METHODS: A systematic literature search of Medline, Embase, Web of Science, and the Cochrane Library through April 8, 2019, was conducted. We included case series of adult patients who died in the hospital and were reviewed by physicians to determine if the death was preventable. Two reviewers independently performed data extraction and study quality assessment. The proportion of preventable deaths from individual studies was pooled using a random-effects model. RESULTS: Sixteen studies met inclusion criteria. Eight studies of consecutive or randomly selected cohorts including 12,503 deaths were pooled. The pooled rate of preventable mortality was 3.1% (95% CI 2.2-4.1%). Two studies also reported rates of preventable mortality limited to patients expected to live longer than 3 months, ranging from 0.5 to 1.0%. In the USA, these estimates correspond to approximately 22,165 preventable deaths annually and 7150 deaths for patients with greater than 3-month life expectancy. DISCUSSION: The number of deaths due to medical error is lower than previously reported and the majority occur in patients with less than 3-month life expectancy. The vast majority of hospital deaths are due to underlying disease. Our results have implications for the use of hospital mortality rates for quality reporting and reimbursement.
