Background Postpartum depression (PPD) has been associated with adverse health outcomes including maternal suicide. Mode of delivery has been suggested to be a risk factor for PPD, but no large cohort study has examined the association between mode of delivery and PPD. We aimed to examine the association between mode of delivery and risks of PPD at 1 and 6 months after childbirth. Methods In a nationwide study of 89,954 mothers with a live singleton birth, we examined the association between mode of delivery and risks of PPD. PPD was measured by the Edinburgh Postnatal Depression Scale (≥13) at 1 and 6 months after childbirth. Odds ratios (ORs) with 95% confidence intervals (CIs) of PPD were calculated using multivariable logistic regression analyses after adjustment of antenatal physical, socioeconomic, and mental factors. Results Among 89,954 women, 3.7% and 2.8% had PPD at 1 and 6 months after childbirth, respectively. Compared with unassisted vaginal delivery, cesarean section (CS) was marginally associated with PPD at 1 month, but not at 6 months; adjusted ORs were 1.10 (95% CI, 1.00-1.21) and 1.01 (95% CI, 0.90-1.13), respectively. The association with PPD at 1 month was evident in women with antenatal psychological distress: adjusted OR was 1.15 (95% CI, 1.03-1.28). The observed associations were attenuated after adjusting for infant feeding method. Conclusions Women who had antenatal psychological distress and underwent CS delivery may be regarded as a target for monitoring PPD.

Background Early specialist evaluation during rapid proliferative growth of complicated infantile hemangiomas (IH) is crucial. Health disparities and barriers of access-to-care for children with IH have not been examined. Objective Investigate whether socioeconomic status (SES) is associated with age at subspecialist presentation for IH evaluation. Method Retrospective cohort study of 804 children presenting to a large academic hospital. Primary outcome was age at initial presentation. Covariates included demographic, socioeconomic, geographic, and clinical characteristics. Medicaid or Children's Health Insurance Program (CHIP) were proxies for lower SES. Analysis of covariance, χ2 tests, and generalized ordered logistic regressions were performed. Results Children with lower SES had higher odds of presenting after 3 months of age (OR 2.11, 95% CI 1.31-3.38). In the subset that qualified for institutional care management program (ICMP), no risk factors were associated with delayed presentation. Limitations Use of insurance and economic distress as proxies for SES; exclusion of uninsured children may underestimate racioethnic effects; single academic center study limiting generalizability. Conclusions Children with IH and lower SES were more likely to present later to specialists, but those enrolled in an ICMP did not, suggesting that integrated ICMPs may mitigate disparities and delayed access-to-care for IH among lower SES populations.

PURPOSE: Hip fractures among elderly patients are surgical emergencies. During COVID-19 pandemic time, many such patients could not be operated at early time because of the limitation of the medical resources, the risk of infection and redirection of medical attention to a severe infective health problem. METHODS: A search of electronic databases (PubMed, Medline, CINAHL, EMBASE and the Cochrane Central Register of Controlled Trials) with the keywords "COVID", "COVID-19″, "SARS-COV-2", "Corona", "pandemic", "hip fracture", "trochanteric fracture" and "neck femur fracture" revealed 64 studies evaluating treatment of hip fracture in elderly patients during COVID-19 pandemic time. The 30-day mortality rate, inpatient mortality rate, critical care/special care need, readmission rate and complications rate in both groups were evaluated. Data were analyzed using Review Manager (RevMan) V.5.3. RESULTS: After screening, 7 studies were identified that described the mortality and morbidity in hip fractures in both COVID-19 infected (COVID-19 +) and non-infected (COVID-19 -) patients. There were significantly increased risks of 30-day mortality (32.23% COVID-19 + death vs. 8.85% COVID-19 - death) and inpatient mortality (29.33% vs. 2.62%) among COVID-19 + patients with odds ratio (OR) of 4.84 (95% CI: 3.13-7.47, p

Background Latent tuberculosis infection (LTBI) diagnosis in a country with a low tuberculosis burden is complicated. Since the prevalence of LTBI in second generation immigrants has not been well recognized, we conducted a cross-sectional study which aimed to explore the differences in LTBI prevalence between offspring of immigrants from high tuberculosis (TB) burden countries and those whose parents were born in countries with a low TB burden. Methods Between May 2014 and April 2018 young native Israelis who were required to perform pre-occupational tuberculin skin tests (TST) (medical and paramedical personnel or teaching assistants of immigrants from high TB burden countries) and who had a TST result of 10 mm and above were tested for QuantiFERON-TB In Tube (QFT-GIT). Statistical comparisons were made between second generation immigrants and those with both parents from a low TB burden country. Results Of 102 patients, 71 were born to parents both of whom were from low-risk countries, 14 to one parent from a high-risk country and 17 to parents both of whom were from a high-risk country. The odds ratio for LTBI was 4.5 (95% CI, 1.2–17.2; p = 0.03) if both parents were born in a high-risk country compared to both parents being from a low-risk country and 4.01 (95% CI, 1.12–14.3; p = 0.03) higher compared to persons for whom at least one parent was born in a low-risk country. Conclusion The risk for latent TB is significantly higher in second generation immigrants if both parents were born in a high-risk country. IGRA should be considered before treatment to patients with a positive TST if at least one parent was born in a low-risk country in order to confirm LTBI.

Objective The study objective was to investigate the impact of multiple arterial grafting on long-term all-cause mortality in women undergoing isolated coronary artery bypass grafting. Methods A comprehensive search was performed to identify observational studies reporting outcomes after coronary artery bypass grafting reported by sex and stratified into multiple arterial grafting versus single arterial grafting strategies. Articles were considered for inclusion if they were written in English and were propensity-matched observational studies. Included studies were then pooled in a meta-analysis performed using the generic inverse variance method. The primary outcome was long-term all-cause mortality. Secondary outcomes were operative mortality and spontaneous myocardial infarction. Meta-regression was used to explore the effects of preoperative and intraoperative variables on the primary outcome. Results A total of 6 studies with 32,793 women (25,714 single arterial grafting and 7079 multiple arterial grafting) were included. Women who received multiple arterial grafting had lower long-term mortality (incidence rate ratio, 0.86; 95% confidence interval, 0.76-0.96; P = .007) and spontaneous myocardial infarction (incidence rate ratio, 0.80; 95% confidence interval, 0.68-0.93; P = .003) compared with women who received single arterial grafting, but the difference in mortality disappeared when including only the 3 largest studies. There was no difference between groups in operative mortality (odds ratio, 0.99; 95% confidence interval, 0.84-1.17; P = .91). Meta-regression did not identify any associations with the incidence rate ratio for long-term mortality. Conclusions The use of multiple arterial grafting in women undergoing coronary artery bypass grafting is associated with lower long-term mortality, although the difference is mostly driven by small series. Further studies, including randomized trials, are needed to evaluate the efficacy of multiple arterial grafting in women undergoing coronary artery bypass grafting.

OBJECTIVE: Female sex is a known risk factor in most cardiac surgery, including coronary and valve surgery, but unknown in acute type A aortic dissection repair. METHODS: From 1996 to 2018, 650 patients underwent acute type A aortic dissection repair; 206 (32%) were female, and 444 (68%) were male. Data were collected through the Cardiac Surgery Data Warehouse, medical record review, and National Death Index database. RESULTS: Compared with men, women were significantly older (65 vs 57 years, P < .0001). The proportion of women and men inverted with increasing age, with 23% of patients aged less than 50 years and 65% of patients aged more than 80 years being female. Women had significantly less chronic renal failure (2.0% vs 5.4%, P = .04), acute myocardial infarction (1.0% vs 3.8%, P = .04), and severe aortic insufficiency. Women underwent significantly fewer aortic root replacements with similar aortic arch procedures, shorter cardiopulmonary bypass times (211 vs 229 minutes, P = .0001), and aortic crossclamp times (132 vs 164 minutes, P < .0001), but required more intraoperative blood transfusion (4 vs 3 units) compared with men. Women had significantly lower operative mortality (4.9% vs 9.5%, P = .04), especially in those aged more than 70 years (4.4% vs 16%, P = .02). The significant risk factors for operative mortality were male sex (odds ratio, 2.2), chronic renal failure (odds ratio, 3.4), and cardiogenic shock (odds ratio, 6.8). The 10-year survival was similar between sexes. CONCLUSIONS: Physicians and women should be cognizant of the risk of acute type A aortic dissection later in life in women. Surgeons should strongly consider operations for acute type A aortic dissection in women, especially in patients aged 70 years or more.

OBJECTIVE Arthritis is a common chronic condition in the ageing population. Its impact on physical function varies according to sociodemographic and race/ethnic factors. The study objective was to examine the impact of arthritis on physical function and disability among non-disabled older Mexican Americans over time. DESIGN A 23-year prospective cohort study of 2230 Mexican Americans aged 65 years and older from the Hispanic Established Population for the Epidemiologic Study of the Elderly (1993/94-2016). The independent variable was self-reported physician-diagnosed arthritis, and the outcomes included Activities of Daily Living (ADL), Instrumental Activities of Daily Living (IADL), mobility, Short Physical Performance Battery (SPPB), and handgrip strength. Covariates were sociodemographic, medical conditions, body mass index, depressive symptoms, and cognitive function. General linear mixed models were performed to estimate the change in SPPB and muscle strength. General Equation Estimation models estimated the odds ratios (OR) of becoming ADL- or IADL- or mobility - disabled as a function of arthritis. All variables were used as time-varying except for sex, education, and nativity. RESULTS Overall, participants with arthritis had higher odds ratio (OR) of any ADL [OR = 1.35, 95% Confidence Interval (CI) = 1.09-1.68] and mobility (OR = 1.34, 95% CI = 1.18-1.52) disability over time than those without arthritis, after controlling for all covariates. Women, but not men, reporting arthritis had increased risk for ADL and mobility disability. The total SPPB score declined 0.18 points per year among those with arthritis than those without arthritis, after controlling for all covariates (p-value

Objectives:To test the hypothesis that higher level of purpose in life is associated with lower likelihood of dementia and mild cognitive impairment (MCI) in older Brazilians.Methods:As part of the Pathology, Alzheimer’s and Related Dementias Study (PARDoS), informants of 1,514 older deceased Brazilians underwent a uniform structured interview. The informant interview included demographic data, the Clinical Dementia Rating scale to diagnose dementia and MCI, the National Institute of Mental Health Diagnostic Interview Schedule for depression, and a 6-item measure of purpose in life, a component of well-being.Results:Purpose scores ranged from 1.5 to 5.0 with higher values indicating higher levels of purpose. On the Clinical Dementia Rating Scale, 940 persons (62.1%) had no cognitive impairment, 121 (8.0%) had MCI, and 453 (29.9%) had dementia. In logistic regression models adjusted for age at death, sex, education, and race, higher purpose was associated with lower likelihood of MCI (odds ratio = .58; 95% confidence interval [CI]: .43, .79) and dementia (odds ratio = .49, 95% CI: .41, .59). Results were comparable after adjusting for depression (identified in 161 [10.6%]). Neither race nor education modified the association of purpose with cognitive diagnoses.Conclusions:Higher purpose in life is associated with lower likelihood of MCI and dementia in older black and white Brazilians.

Objectives Information on knowledge of public health professionals about health aspects of the human–animal interface, referred to as One Health, is limited. The objective of this study was to identify factors associated with animal welfare attitudes, practices, and One Health awareness among US Public Health Service (USPHS) officers to assess preparedness for public health response. Methods USPHS officers participated in an online, self-administered survey from February 15 through March 2, 2018. A total of 1133 of 6474 (17.5%) USPHS officers responded. We collected information on officers’ demographic characteristics, animal welfare attitudes and practices, volunteer and work exposure to animals, and One Health knowledge. We compared (1) One Health knowledge and animal work exposure (deployment, regular assignment, or none) and (2) animal welfare importance and animal work exposure. To adjust for demographic characteristics associated with One Health knowledge, we used multivariable logistic regression. Results One-third of nonveterinary officers reported encountering animals during deployment, and 65% reported that animal welfare was very or extremely important. We found no difference in One Health knowledge between nonveterinary officers who participated in deployments involving animals and nonveterinary officers who had no work exposure to animals (adjusted odds ratio [aOR] = 1.11; 95% CI, 0.71-1.75). Nonveterinary officers who participated in animal-related public health activities during regular assignment were more likely to have One Health knowledge than nonveterinary officers who had no work exposure to animals (aOR = 7.88; 95% CI, 5.36-11.59). Conclusions One Health knowledge and awareness should be further explored in the current US public health workforce to identify training needs for emergency preparedness and other collaborative opportunities.

Objectives Human papillomavirus (HPV) vaccination coverage in the United States is far below coverage for other routine adolescent vaccines. We examined whether missed opportunities for HPV vaccination among adolescents differ by parental nativity (country of origin) in Minnesota. Methods We retrospectively analyzed birth record and immunization information data for adolescents in Minnesota born during 2004-2007 using data from January 1, 2015, through December 31, 2018. Using logistic regression, we assessed the association between parental nativity and missed opportunities for HPV vaccine initiation, or receipt of other vaccines without receipt of the HPV vaccine. We adjusted for parent/child demographic and vaccination characteristics. We defined nativity as the number of non–US-born parents and maternal region of birth. Results Adolescents with mothers born in Eastern Europe (adjusted odds ratio [aOR] = 2.33; 95% CI, 2.01-2.73) and Africa (aOR = 1.36; 95% CI, 1.28-1.43) had greater adjusted odds of missed opportunities for HPV vaccination than adolescents with US-born mothers. However, adolescents with mothers from Latin America and the Caribbean had lower odds of missed opportunities than adolescents with US-born mothers (aOR = 0.61; 95% CI, 0.58-0.65). Adolescents with 1 or 2 non–US-born parents had lower odds of missed opportunities for HPV vaccination than adolescents with 2 US-born parents (1 parent: aOR = 0.92; 95% CI, 0.88-0.96; 2 parents: aOR = 0.90; 95% CI, 0.87-0.94). Conclusions Future studies should evaluate outreach to groups with HPV vaccination disparities and identify other drivers of missed opportunities among adolescents with US-born parents, such as multiparity.

Background Gastric cancer is worldwide the fourth more common cancer type by incidence, and the third by mortality. We analyzed three missense variants of TAS2R38 gene: rs713598 (A49P), rs1726866 (V262A), and rs10246939 (I296V). These variants and their combination in haplotypes (proline, alanine and valine/tasters or alanine, valine and isoleucine/nontasters) and diplotypes are responsible for individual differences in bitter perception. The single-nucleotide polymorphisms and the related phenotypes are known to be associated with susceptibility to Gram-negative bacterial infections, such as Helicobacter pylori, and with risk of various cancer types. An association between intermediate tasters (as defined by TAS2R38 diplotypes) and increased risk of gastric cancer was reported in a Korean population. Methods We analyzed 2616 individuals of Latin American origin, representing the whole spectrum of lesions from gastritis to gastric cancer. Results Comparing cancer cases vs. noncancers we observed a decrease in risk associated with heterozygous carriers of rs10246939 (P = 0.006) and rs1726866 (P = 0.003) when compared with homozygotes of the more common allele. Also, the analysis of diplotypes/phenotypes reflected the same association, with super-tasters showing a borderline increased risk of developing gastric cancer compared to medium-tasters [odds ratio (OR) = 1.63; 95% confidence interval (CI), 1.04-2.56; P = 0.033]. Also, nontasters showed an increased risk when compared to medium-tasters although not reaching statistical significance (OR = 1.58; 95% CI, 0.80-2.87; P = 0.203). We also tested the interactions between the TAS2R38 genotypes and H. pylori cagA status in a subset of samples and found no interaction. Conclusion In conclusion, our results suggest only a modest contribution of TAS2R38 gene genetic variability in gastric cancer etiology.

Introduction The authors tested the hypothesis that the EEG feature generalized polyspike train (GPT) is associated with drug-resistant idiopathic generalized epilepsy (IGE). Methods The authors conducted a single-center case-control study of patients with IGE who had outpatient EEGs performed between 2016 and 2020. The authors classified patients as drug-resistant or drug-responsive based on clinical review and in a masked manner reviewed EEG data for the presence and timing of GPT (a burst of generalized rhythmic spikes lasting less than 1 second) and other EEG features. A relationship between GPT and drug resistance was tested before and after controlling for EEG duration. The EEG duration needed to observe GPT was also calculated. Results One hundred three patients were included (70% drug-responsive and 30% drug-resistant patients). Generalized polyspike train was more prevalent in drug-resistant IGE (odds ratio, 3.8; 95% confidence interval, 1.3-11.4; P = 0.02). This finding persisted when controlling for EEG duration both with stratification and with survival analysis. A median of 6.5 hours (interquartile range, 0.5-12.7 hours) of EEG recording was required to capture the first occurrence of GPT. Conclusions The findings support the hypothesis that GPT is associated with drug-resistant IGE. Prolonged EEG recording is required to identify this feature. Thus, >24-hour EEG recording early in the evaluation of patients with IGE may facilitate prognostication.

Background Impact of immeasurable time bias (IMTB) is yet to be examined in self-controlled designs. Methods We conducted case-crossover, case-time-control, and case-case-time-control analyses using Korea's healthcare database. Two empirical examples among elderly patients were used: 1) benzodiazepines-hip fracture; 2) benzodiazepines-mortality. For cases, the date of hip fracture diagnosis or death was defined as the index date, and the inherited date of their matched cases for controls or future cases. Exposure was assessed in the 1-30 day (hazard) and 61-90 day (control) windows preceding the index date. A non-missing exposure setting included in- and outpatient prescriptions and the pseudo-outpatient setting included only the outpatients. Conditional logistic regression was done to estimate odds ratio (OR) with 95% confidence intervals (CI), where the relative difference in OR among the two settings was calculated to quantify the IMTB. Results The IMTB had negligible impacts in the hip fracture example in the case-crossover (non-missing exposure setting OR 1.27, 95% CI 1.12-1.44; pseudo-outpatient setting 1.21, 1.06-1.39; magnitude 0.05), case-time-control (1.18, 0.98-1.44; 1.13, 0.92-1.38; 0.04), and case-case-time-control analyses (0.99, 0.80-1.23; 0.94, 0.75-1.18; 0.05). In the mortality example, IMTB had significant impacts in the case-crossover (1.44, 1.36-1.52; 0.72, 0.67-0.78; 1.00), case-time-control (1.38, 1.26-1.51; 0.68, 0.61-0.76; 1.03), and case-case-time-control analyses (1.27, 1.15-1.40; 0.62, 0.55-0.69; 1.05). Conclusions Although IMTB had negligible impacts on the drug's effect on acute events as these are unlikely to be accompanied with hospitalizations, it negatively biased the drug's effect on mortality, an outcome with prodromal phases, in the three self-controlled designs.

Background There is limited evidence regarding the relationship between Diabetes mellitus (DM) in middle age and mild cognitive impairment after a follow-up. Therefore, we investigated the relationship between fasting blood glucose (FBG) levels in middle age and cognitive function (assessed using the Japanese version of the Montreal Cognitive Assessment (MoCA-J) in later life, following over 15 years of follow-up in the Aichi Workers' Cohort Study in Japan. Methods Participants were 253 former local government employees aged 60-79 years in 2018 who participated in a baseline survey conducted in 2002. Using baseline FBG levels and self-reported history, participants were classified into the normal, impaired fasting glucose (IFG) and, and DM groups. Total MoCA-J score ranges from 0 to 30, and cognitive impairment was defined as MoCA-J score ≤25 in this study. A general linear model was used to estimate the mean MoCA-J scores in the FBG groups, adjusted for age, sex, educational year, smoking status, alcohol consumption, physical activity, body mass index, systolic blood pressure, total cholesterol, and estimated glomerular filtration rate. Results The mean MoCA-J score in the total population was 25.0, and the prevalence of MoCA-J score ≤25 was 49.0%. Multivariable-adjusted total MoCA-J scores were 25.2, 24.8, and 23.4 in the normal, IFG, and DM groups, respectively. The odds ratio of MoCA-J score ≤25 in the DM group was 3.29. Conclusions FBG level in middle age was negatively associated with total MoCA-J scores assessed later in life, independent of confounding variables.

Purpose: Postoperative acute kidney injury is common and associated with increased length of hospital stay, costs and mortality. The impact from postoperative subclinical changes in plasma concentration of creatinine (p-creatinine) on postoperative mortality has received less attention. In this study, the association between the postoperative change of p-creatinine and all-cause mortality was investigated. Methods: A single-centre register-based, retrospective study was conducted including patients ≥ 60 years undergoing open abdominal surgery from 2000 to 2013. Postoperative p-creatinine change was analysed for association with 30-day mortality following adjustment for age, gender, surgical setting and surgical procedure. Main findings A total of 3,460 patients were included in the study of whom 67.6% underwent emergency surgery. The 30-day mortality rate was 18.3%, and a given 10 μmol/L daily postoperative increase in p-creatinine was associated with an increased mortality risk with an odds ratio (OR) of 2.67 (95% CI; 2.28-3.14, P < 0.001). In patients undergoing emergency surgery, a daily 10 μmol/L increase in p-creatinine increased the risk for a fatal outcome a 2.39 OR (CI 95%; 2.05-2.78), P < 0.001). In patients undergoing elective surgery, a similar increase in p-creatinine increased risk of postoperative death with a 28.85 OR (CI 95%; 10.25-81.19). Conclusion: Even a minor postoperative p-creatinine increase following open abdominal surgery below the criteria for acute kidney injury was associated with increased 30-day mortality in patients aged 60 years or above.

Objective To assess the concordance of tumour grade in specimens obtained from diagnostic cystoscopic biopsy and transurethral resection of bladder tumour (TURBT) and explore the risk factors of upgrading. Methods The medical records of 205 outpatients who underwent diagnostic cystoscopic biopsy before initial TURBT were retrospectively reviewed. Comparative analysis of the tumour grade of biopsy and operation specimens was performed. Tumour grade changing from low-grade (LG) to high-grade (HG) with or without variant histology was defined as upgrading. Univariate and multivariate logistic regression analyses were performed to identify the risk factors of upgrading. Results For the 205 patients, the concordance of tumour grade between biopsy and operation was 0.639. The concordance for patients who were preoperatively diagnosed with LG and HG was 0.504 and 0.912, respectively. Univariate and multivariate logistic regression analyses showed that older age, tumour multifocality, high neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and low lymphocyte-to-monocyte ratio (LMR) were significantly associated with upgrading (odds ratio [OR] ranging from 0.412 to 4.364). The area under the curve of the different multivariate models was improved from 0.752 to 0.821, and decision curve analysis demonstrated a high net benefit when NLR, LMR, and PLR were added. Moreover, the nomogram was well calibrated. Conclusions Diagnostic cystoscopic biopsy may not accurately represent the true grade of new bladder cancer, especially for outpatients with LG. Moreover, older age, tumour multifocality, high NLR, PLR, and low LMR are risk factors of upgrading, and systemic inflammatory markers improve the predictive ability.

Objective To evaluate the long-term stone free rate (SFR) of retrograde intra-renal surgery (RIRS) in the treatment of lower pole renal calculi using only basket relocation and identify independent predictors of stone-free status. All consecutive patients treated with RIRS lower pole renal calculi in a single high-volume tertiary center. Methods All consecutive patients underwent RIRS lower pole renal calculi at a single high-volume tertiary center were analyzed retrospectively. Lower pole stones were relocated to the upper pole, where laser lithotripsy was performed. All patients were followed up in the clinic following the surgery and yearly thereafter. The stone-free status was assessed with a combination of an abdominal ultrasound and abdominal X-ray (KUB), or an abdominal non-contrast computed tomography (NCCT) if the stones were known to be radiolucent. Results A total of 480 consecutive patients who underwent RIRS for treatment of lower pole renal calculi, between January 2012 and December 2018, were analyzed from a prospectively maintained database of 3000 ureteroscopies. With a median follow-up time of 18.6 months, the mean SFR was 94%. The procedures were unsuccessful in 26 (5.4%) due to unreachable stones. The median stone size of the unreachable stones was 12 mm (range 10–30 mm). Multivariable logistic regression analysis revealed two predictors of SFR for lower pole stones: A small cumulative stone burden (Odds Ratio [OR]: 0.881, 95% confidence interval [CI]: 0.731–1.062, p Conclusions The long-term SFR of RIRS for the treatment of lower pole stones with basket displacement with appropriate patient selection is high. In our study, the SFR, at a median follow up of 18.6 months (range 6–161 months), was 94%.

Objective Scleroderma renal crisis (SRC) is a rare and severe manifestation of systemic sclerosis (SSc). Although it is well documented that Blacks with SSc have worse morbidity and mortality than non-Blacks, racial predilection for SRC is underreported. We examine the association of race and future development of SRC in an SSc cohort. Methods Using the electronic health record of the United States Military Health System, we conducted a comprehensive chart review of each patient with SSc from 2005 to 2016. The final study cohort was comprised of 31 SRC cases and 322 SSc without SRC controls. We conducted logistic regression of SRC as the outcome variable and race (Black vs. non-Black) as the primary predictor variable, adjusted for age, estimated glomerular filtration rate, hypertension and proteinuria at SSc diagnosis. Results Out of 353 patients, 294 had identifiable race (79 Black, 215 non-Black). Thirteen out of 79 Blacks (16.5%) vs. 16/215 (7.4%) non-Blacks developed SRC (p=0.02). On adjusted analysis, Blacks had a significantly higher risk of developing SRC than non-Blacks (odds ratio 6.4, 95% CI 1.3-31.2, p=0.02). Anti-Ro antibody was present in a higher proportion of Black SRC patients vs. Blacks without SRC [45% vs. 14%, p=0.01]. Conversely, older age, thrombocytopenia, and anti-RNA polymerase III antibody at SSc diagnosis were significantly associated with future SRC in the non-Black cohort. Conclusion Black race was independently associated with a higher risk of future SRC. Further studies are needed to elucidate the mechanisms that underlie this important association.

BACKGROUND Burkholderia cepacia complex (BCC) represents a group of multidrug-resistant gram-negative bacteria that cause infections among immunocompromised hosts. Bacteremia occurs in patients who are chronically ill and is associated with substantial morbidity and mortality. The aim of this study was to investigate the clinical characteristics and outcomes of BCC bacteremic patients without cystic fibrosis. METHODS We conducted a retrospective study at the National Taiwan University Hospital. Adults with BCC bacteremia from January 2015 to May 2019 were enrolled. The primary outcome was 14-day mortality. Multivariable logistic regression was performed for outcome analysis. RESULTS One-hundred and ninety-five patients were analyzed and their mean age was 67 years. Over 95% of the BCC isolates were susceptible to trimethoprim/sulfomethoxazole (TMP/SXT). Levofloxacin resistance rates were high, with only 25.1% of isolates being susceptible. Pairwise comparisons were made between different definitive regimens including meropenem-monotherapy, ceftazidime-monotherapy, levofloxacin-monotherapy, TMP/SXT-monotherapy, tigecycline-monotherapy as well as combination versus monotherapy. No regimen was significantly associated with survival in our study. Multivariable logistic regression showed that the Pitt bacteremia score (adjust odds ratio [aOR],1.46; 95% confidence interval [CI],1.19-1.79; p

Objective To compare the incidence of endophthalmitis after intravitreal anti-vascular endothelial growth factor (anti-VEGF) injections with and without patient face masking. Design Two-centre retrospective cohort study Participants Patients receiving a total of 28 501 injections (period 1 before masking: n = 13 863; period 2 after masking: n = 14 638) Methods Periods before and after implementation of patient masking were compared: period 1 (July–December 2019) and period 2 (July–December 2020). All patients requiring treatment for endophthalmitis following intravitreal anti-VEGF injections were reviewed. Endophthalmitis risks were compared. Statistical simulations were run to determine the number of injections or endophthalmitis cases required to detect a statistically significant difference between both periods. Results Five patients (0.036%) had endophthalmitis in period 1 compared with 7 patients (0.048%) in period 2. Odds ratio, 95% confidence interval, for risk of patient masking was 1.326, 0.421–4.179 (p = 0.63). Three patients (0.022%) in period 1 had culture-positive endophthalmitis compared with 2 patients (0.014%) in period 2. Risk of patient masking for culture-positive endophthalmitis was 0.631, 0.105–3.779 (p = 0.61). Assuming similar rates of endophthalmitis, 476,806 injections in both groups would be required to detect a significant difference. Alternatively, assuming that masking would increase endophthalmitis risk in period 2, a significant difference would require twice as many cases (n = 15, 0.102%) for a risk of 2.843, 1.033–7.825 (p = 0.043). Conclusions The implementation of patient masking in clinical practice did not significantly alter the rate of endophthalmitis following intravitreal anti-VEGF injections.

Background & aims A potential protection against COVID-19 by a high-quality dietary pattern is to be expected given the biological plausibility supporting the beneficial effects of an adequate dietary intake on the immune system. However, knowledge on the relationship between long-term maintained healthy dietary patterns, such as the Mediterranean diet, and the risk of SARS-CoV-2 infection is still sparse. We longitudinally assessed this association in a well-known Mediterranean cohort. Methods We assessed 9,677 participants from the SUN Project, a prospective cohort of middle-aged university graduates in Spain. We inquired about a positive result in a COVID-19 diagnostic test during the months of February to December 2020. After excluding health professionals (HP), 5,194 participants were included in the statistical analyses (mean age: 52.6, SD: 12.4; 55.2% women). Food habits were assessed at baseline using a previously validated semiquantitative 136-item food frequency questionnaire. Adherence to the Mediterranean diet (cumulative average of 2 repeated measurements 10 years apart) was assessed using the 0-to-9 Mediterranean Diet Score (MDS). We used multivariable logistic regression models to estimate odds ratios and 95% confidence intervals for incident COVID-19 according to the MDS. Results Among 5,194 non-HP participants, 122 reported to have received a positive COVID-19 diagnostic test. Participants with intermediate adherence to the Mediterranean diet (3 < MDS ≤ 6) had a significantly lower odds of developing COVID-19 (multivariable-adjusted OR = 0.50, 95% CI: 0.34–0.73), and those with the highest adherence (MDS > 6) exhibited the lowest risk (multivariable-adjusted OR = 0.36, 95% CI: 0.16–0.84, p for trend

Acute kidney injury (AKI) frequently complicates cardiac surgery and is more common among Black patients. We evaluated determinants of race-based differences in AKI rates.Serum creatinine-based criteria were used to identify adult cardiac surgical patients having postoperative AKI in the Perfusion Measures and Outcomes (PERForm) Registry (July 1, 2014, to June 30, 2019). Patient characteristics, operative details, and outcomes were compared by race (Black vs White) after excluding patients with preoperative dialysis, missing preoperative or postoperative creatinine, or other races. A mixed effects model (adjusting for demographics, comorbidities, surgical factors) used hospital as a random effect to predict postoperative stage 2 or 3 AKI. Propensity score analyses were conducted to evaluate robustness of the primary analyses.The study cohort included 34 520 patients (8% Black). More Black patients than White patients were female (43% vs 27%, P.001), and had hypertension (93% vs 87%, P.001) and diabetes mellitus (51% vs 41%, P.001). Acute kidney injury of stage 2 or greater occurred in 1697 patients (5%), more often among Black than White patients (8% vs 5%, P.001). Intraoperatively, Black patients had lower nadir hematocrits (23 vs 26, P.001), and were more likely to be given transfusions (22% vs 14%, P.001). After adjustment, Black race (compared with White) independently predicted odds for postoperative AKI (adjusted odds ratio 1.50; 95% confidence interval, 1.26 to 1.78). The multivariable findings were similar in propensity score analyses.Despite accounting for differences in risk factors and intraoperative practices, Black patients had a 50% increased odds for having moderate-severe postoperative AKI compared with White patients. Additional evaluations are warranted to identify potential targets to address racial disparities in AKI outcomes.

ImportanceAlthough several predictors of COVID-19 vaccine hesitancy have been identified, the role of physical health has not been well-examined, and the association with mental health is unknown.ObjectiveTo examine the association of pre-pandemic mental health, physical health, and shielding with vaccine hesitancy after the announcement of the successful testing of the Oxford University/AstraZeneca vaccine.Design, Setting, and ParticipantsWe used individual-level data from a pandemic-focused investigation (COVID Survey), a prospective cohort study nested within the UK Understanding Society (Main Survey) project. In the week immediately following the announcement of successful testing of the first efficacious inoculation (November/December 2020), data on vaccine intentionality were collected in 12,035 individuals aged 16-95 years. Pre-pandemic, study members had responded to enquiries about diagnoses of mental and physical health, completed the 12-item General Health Questionnaire for symptoms of psychological distress (anxiety and depression), and indicated whether they or someone in their household was shielding.Main outcome measuresSelf-reported intention to take up a vaccination for COVID-19. To summarise our results, we computed odds ratios with accompanying 95% confidence intervals for indices of health and shielding adjusted for selected covariates.ResultsIn an analytical sample of 11,955 people (6741 women), 15.4% indicated that they were vaccine hesitant. Relative to their disease-free counterparts, shielding was associated with a 24% lower risk of being hesitant (odds ratio; 95% confidence interval: 0.76; 0.59, 0.96), after adjustment for a range of covariates which included age, education, and ethnicity. Corresponding results for cardiometabolic disease were 22% (0.78; 0.64, 0.95), and for respiratory disease were 26% (0.74; 0.59, 0.93). Having a pre-pandemic diagnosis of anxiety or depression, or a high score on the distress symptom scale, were all unrelated to the willingness to take up a vaccine.Conclusions and relevancePeople who have been prioritised for COVID-19 vaccination owing to a physical condition are more likely to take it up. These effects were not apparent for indices of mental health.

Background To determine the relationship between hospital surgical volume and mortality risk and valve repair rate in infective endocarditis (IE) surgery. Methods Using the Taiwan National Health Insurance Research Database (NHIRD), 3873 patients were identified who underwent surgery between 2000 and 2013. The cumulative hospital volume of valve surgery for IE was calculated, and patients were divided into 4 subgroups according to the quartile. Outcomes were mortality and valve repair rate and the cut point of referral excellence. Results The distribution of IE surgery has been shifting to lower volume hospitals over the years. The global disease severity (Charlson’s Comorbidity Index score [CCI score]) of patients was greater in the lowest volume hospital than in the highest volume hospital (2.4 vs. 2.0). The crude in-hospital mortality rate was 15.8% and 9.4% for the lowest and highest volume hospitals, respectively, with a significant difference (adjusted odds ratio: 1.86, 95% confidence interval: 1.22–2.85) after adjustment of baseline characteristics including the CCI score. The mitral valve (MV) repair rate increased with the increase in cumulative volume. During a mean follow-up period of 4.4 years, 324 (41.9%) and 254 (30.9%) patients died in the lowest and highest volume subgroups, respectively, and the difference was significant (adjusted hazard ratio: 1.59, 95% CI: 1.21–2.10). Conclusions A higher cumulative volume of IE surgery is associated with a lower risk of mortality and a higher likelihood of successful MV repair. Therefore, interfacility transfer to a high-volume hospital may improve outcomes of IE surgery.

Background/Aims: We aimed to estimate the prevalence of comorbidities and medication use in Korean women with rheumatic diseases (RDs) during their childbearing years.Methods: We included women aged 20 to 44 years with seropositive rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and ankylosing spondylitis (AS) (n = 41,547) and age-matched women without seropositive RA, SLE, and AS (n = 208,941) from the National Health Insurance Service-National Health Information Database (2009 to 2016). The prevalence of hypertension (HTN), hyperlipidemia (HLD), diabetes mellitus (DM), and cancer and the use of nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroids (CSs), and disease-modifying anti-rheumatic drugs (DMARDs) were estimated.Results: Women of childbearing age with RDs were more likely to have at least one of the measured comorbidities than the controls (odds ratio [OR], 3.0; 95% confidence interval [CI], 2.9 to 3.1). The OR (95% CI) was 2.9 (2.8 to 3.0) for HTN, 2.8 (2.7 to 2.9) for HLD, 1.4 (1.4 to 1.5) for DM, and 1.3 (1.3 to 1.4) for cancer. The SLE group had the highest prevalence and odds of all four measured comorbidities. Almost all (97.9%) women of childbearing age with RDs were taking RD-related medications (NSAIDs, 81.6%; CSs, 77.8%; DMARDs, 87.3%). The RD group was 13.8 times more likely to take NSAIDs and 68.2 times more likely to take CSs than the controls. Use of NSAIDs was more prevalent in RA and AS than SLE, whereas use of CSs and DMARDs was more prevalent in RA and SLE than AS.Conclusions: Korean women with RDs have a greater burden of comorbidities and medication use during their childbearing years than women without RDs of the same age.

Background This study assessed associations between processed electroencephalographic (pEEG) use during anesthesia, surgery- and anesthesia-related risk factors, and neurologic outcomes and mortality after cardiac surgery. Methods Drawing from the Society of Thoracic Surgeons Adult Cardiac Surgery Database and its Adult Cardiac Anesthesiology Section, we identified 42,932 records for elective, urgent, and emergency cardiac surgery procedures between July 1, 2017, to December 31, 2019. Using propensity score weighted regression analysis, we analyzed the associations between pEEG use during anesthesia on the primary outcome, postoperative delirium (POD), and secondary outcomes (stroke, encephalopathy, coma, and operative mortality). Results The rate of pEEG use during anesthesia use was 32.8% (n=14,086), and its use was not associated with decreased odds for POD (odds ratio [OR], 0.88; 95%CI, 0.78-1.02) or encephalopathy (OR, 0.85; 95%CI, 0.70-1.03). Intraoperative pEEG monitoring use was also not associated with increased odds for stroke (OR, 1.17; 95%CI, 0.97-1.42) or coma (OR, 1.44; 95%CI, 0.82-2.52). In contrast, pEEG use during anesthesia was associated with higher odds for operative mortality (OR, 1.23; 95%CI, 1.05-1.44). This association remained significant after adjusting for POD (OR: 1.21, 95%CI: 1.03-1.41), stroke (OR: 1.21, 95%CI:1.04-1.42), and encephalopathy (OR: 1.28, 95%CI: 1.07-1.52). Conclusions This large retrospective database study found no association between pEEG use during cardiac surgery and postoperative neurologic outcomes such as POD, stroke, encephalopathy, or coma. However, patients who underwent pEEG monitoring during anesthesia experienced higher mortality, even after adjustment for neurologic outcomes.

We performed a nationwide population-based cohort study to investigate sex differences in the rate of permanent pacemaker implantation after surgical aortic valve replacement (AVR).This study included all adult patients who underwent primary AVR in Sweden between 2005 and 2018. Study data were obtained from the Swedish Web system for Enhancement and Development of Evidence-based care in Heart disease Evaluated According to Recommended Therapies (SWEDEHEART) registry and other Swedish national health-data registers. The rate of permanent pacemaker implantation within 30 days of surgery AVR was compared between men and women. We estimated propensity scores that were used for inverse probability of treatment weighting to account for sex differences in patient characteristics.A total of 18 131 patients were included, 11 657 men (64%) and 6474 women (36%). The rate of permanent pacemaker implantation did not differ between women (3.8%; 95% CI, 3.2%-4.3%) and men (3.7%; 95% CI, 3.3%-4.1%; P = .831). In patients aged60 years, the rate of permanent pacemaker implantation was significantly higher in women (6.2%; 95% CI, 4.3%-8.0%) than in men (3.6%; 95% CI, 2.8%-4.4%; P = .006). The odds of pacemaker implantation in patients aged60 years was significantly higher in women (odds ratio, 1.76; 95% CI, 1.17-2.63; P = .006). In patients aged 60 to 79 years and ≥80 years, the rate of pacemaker implantation did not differ between men and women.The rate of permanent pacemaker implantation after surgical AVR in patients aged60 years was higher in women than in men. The susceptibility to conduction disturbances requiring permanent pacemaker implantation in women aged60 years warrants further investigation and should be recognized as transcatheter aortic valve replacement expands into younger patients.

Objectives This study was to explore the potential relationship between the fibrinogen-to-albumin ratio (FAR) and the presence and severity of coronary artery disease (CAD) in stage 3–5 predialysis chronic kidney disease (CKD) patients. Design This study included 978 patients undergoing coronary angiography (CAG). CAD was defined as the presence of obstructive stenosis > 50% of the lumen diameter in any of the four main coronary arteries. Gensini scores (GSs), left main coronary artery (LMCA) and three-vessel coronary artery disease (TVD) were used to elevate the severity of CAD. Results The adjusted odds ratios of CAD were 3.059 (95% CI: 1.859–5.032) and 2.670 (95% CI: 1.605–4.441) in the third and fourth quartiles of FAR compared with the first quartile, respectively. Among 759 patients diagnosed with CAD, multivariate logistic regression analysis showed that FAR (at the 0.01 level) was significantly positively associated with the presence of LMCA (adjusted OR = 1.177, 95% CI 1.067–1.299, P = 0.001) or TVD (adjusted OR = 1.154, 95% CI 1.076–1.238, P Conclusions FAR levels were independently associated with the presence and severity of CAD in stage 3–5 predialysis CKD patients.

Purpose: The aim of this study was to assess frequency and risk factors of severe bleeding after proctological surgery requiring hemostatic surgery observed after publication of the French guidelines for anticoagulant and platelet-inhibitor treatment.Methods: All patients who underwent proctological surgery between January 2012 and March 2017 in a referral center were included. Delay, severity of bleeding, and need for blood transfusion were recorded. Patients with severe postoperative bleeding were matched to controls at a 2:1 ratio adjusted on the operator, and the type of surgery.Results: Among the 8,890 operated patients, 65 (0.7%) needed a postoperative hemostatic procedure in an operating room. The risk of a hemostatic surgery was significantly increased after hemorrhoidal surgery compared with other procedures (1.9% vs. 0.5%, P–4) and was most frequent after Milligan-Morgan hemorrhoidectomy (2.5%). Mean bleeding time was 6.2 days and no bleeding occurred after day 15. Blood transfusion rate was 0.1%. Treatment with anticoagulants and platelet inhibitors were managed according to recommendations and did not increase the severity of bleeding. The risk of severe bleeding was significantly lower in active smokers vs. non-smokers in univariate (16.9% vs. 36.2%, P=0.007) and multivariate (odds ratio, 0.31; 95% confidence interval, 0.14–0.65) analysis whereas sex, age, and body mass were not significantly associated with bleeding.Conclusion: Severe postoperative bleeding occurs in 0.7% of patients, but varies with type of procedure and is not affected by anticoagulant or antiplatelet treatment. These treatments given in accordance with the new guidelines do not increase the severity of postoperative bleeding.

OBJECTIVE Police and emergency services personnel are at an increased risk of developing mental health issues. We sought to compare patterns of exposure to work-related and nonwork stressors and associations with posttraumatic stress symptoms and psychological distress among police and emergency services employees. METHOD A total of 14,868 employees from 33 ambulance, fire and rescue, police, and state emergency service agencies around Australia participated in a survey to assess the prevalence of exposure to work-related and nonwork stressors, and the prevalence of mental health conditions. Associations between work and nonwork stressors and mental health problems were estimated using logistic regression models and population attributable risk (PAR) percentages. RESULTS Traumatic events experienced while working in the police and emergency services sector were the most frequently reported stressor (51%). Stressful events experienced at work in the sector were associated with significantly higher levels of suspected posttraumatic stress symptoms (odds ratio = 4.5, PAR = 65%) and high psychological distress (odds ratio = 2.5, PAR = 40%) compared to stressors experienced away from the sector. CONCLUSIONS Stressors experienced at work are a risk factor for developing posttraumatic stress symptoms and distress in the sector. Organizations should have comprehensive policies and programs to help prevent the development of mental health problems and to support personnel who develop mental health problems.

Alcohol use presents a serious risk to women's health. Of particular interest is the association of harmful alcohol consumption and risky behaviors, such as drinking before sexual intercourse, an understudied phenomenon in the Mexican population. AIM The aim of this study was to identify whether the harmful use of alcohol is associated with an increased probability of presex drinking in Mexican young women. METHOD This was a study with a predictive design. Multiple logistic regressions were performed in a random sample of 304 young college women (between the ages of 18 and 24 years) from Guanajuato and Tamaulipas, Mexico. Participants completed a sociodemographic data survey and the Alcohol Use Disorders Identification Test questionnaire. RESULTS Women with a pattern of harmful use of alcohol were more likely to report drinking before sex (adjusted odds ratio = 4.679, 95% confidence interval [1.619, 13.520], McFadden's pseudo R2 = 25.5%). Further analyses revealed that presex drinking by partners was an even stronger predictor of alcohol use before sexual intercourse in women (adjusted odds ratio = 12.749, 95% confidence interval [4.714, 34.483], McFadden's pseudo R2 = 34.7%). CONCLUSIONS The findings demand additional nursing studies to corroborate-and to better understand-the relationship between harmful use of alcohol in Mexican women, their partners' drinking behavior, and unhealthy behaviors like drinking before sexual intercourse.

BACKGROUND AND OBJECTIVE Studies have reported an increased tuberculosis (TB) incidence among patients with end-stage renal disease (ESRD). This nationwide nested Case-control study investigated the risk of active TB due to nosocomial exposure and its correlation with the delay in TB treatment in hemodialysis patients. METHODS Adult (aged ≥20 years) patients with incident ESRD over 2000-2010 were identified from Taiwan National Health Insurance Research Database; 2331 patients with incident active TB (Case) were matched with 11,655 patients without TB (control) by age, sex, year of ESRD onset, Charlson comorbidity index, chronic obstructive pulmonary disease, and diabetes mellitus, at a 1:5 case-to-control ratio. RESULTS Compared with the control group, the Case group had greater nosocomial exposure to index patients with pulmonary TB (2.36 vs. 0.11 month of exposure, p

Objective To investigate the incidence of and factors associated with SARS-CoV-2 testing and infection in immune mediated inflammatory diseases (IMIDs) versus matched non-IMIDs comparators from the general population. Methods We conducted a population-based, matched cohort study among adult residents from Ontario, Canada, from January to December 2020. We created cohorts for the following IMIDs: rheumatoid arthritis (RA), psoriasis, psoriatic arthritis, ankylosing spondylitis, systemic autoimmune rheumatic diseases, multiple sclerosis (MS), iritis, inflammatory bowel disease (IBD), polymyalgia rheumatica and vasculitis. Each patient was matched with five patients without IMIDs based on socio-demographic factors. We estimated the incidence of SARS-CoV-2 testing and infection in IMIDs and non-IMIDs patients. Multivariable logistic regressions assessed odds of SARS-CoV-2 infection. Results We studied 493,499 patients with IMIDs and 2,466,946 patients without IMIDs. Patients with IMIDs were more likely to have at least one SARS-CoV-2 test, versus patients without IMIDs (27.4% vs. 22.7%), but the proportion testing positive for SARS-CoV-2 was identical (0.9% in both groups). Overall, IMIDs patients had 20% higher odds of being tested for SARS-CoV-2 (odds ratio (OR) 1.20, 95% CI 1.19, 1.21). The odds of SARS-CoV-2 infection varied across IMIDs groups but was not significantly elevated for most IMID groups compared with non-IMIDs. The odds of SARS-CoV-2 infection was lower in IBD and MS and marginally higher in RA and iritis. Conclusions Patients across all IMIDs were more likely to be tested for SARS-CoV-2 versus those without IMIDs. The risk of SARS-CoV-2 infection varied across disease sub-groups.

To investigate previously identified and novel correlates of acute calcium pyrophosphate (CPP) crystal arthritis among well-characterized cases.In this case-control study, we identified cases of acute CPP crystal arthritis using a validated algorithm (positive predictive value 81%) applied in the Partners HealthCare electronic health record (EHR). Cases were matched to general patient controls on the year of first EHR encounter and index date. Prespecified potential correlates included sex, race, and comorbidities and medications previously associated with CPP deposition/acute CPP crystal arthritis in the literature. We estimated odds ratios (ORs) and 95% confidence intervals using conditional logistic regression models adjusted for demographic characteristics, comorbidities, medications prescribed in the past 90 days, health care utilization, and multimorbidity score.We identified 1,697 cases matched to 6,503 controls. Mean ± SD age was 73.7 ± 11.8 years, 56.7% were female, 80.8% were White, and 10.3% were Black. All prespecified covariates were more common in cases than controls. Osteoarthritis (OR 3.08), male sex (OR 1.35), rheumatoid arthritis (OR 2.09), gout (OR 2.83), proton pump inhibitors (OR 1.94), loop diuretics (OR 1.60), and thiazides (OR 1.46) were significantly associated with acute CPP crystal arthritis after full adjustment. Black race was associated with lower odds for acute CPP crystal arthritis compared to White race (OR 0.47).Using a validated algorithm to identify nearly 1,700 patients with acute CPP crystal arthritis, we confirmed important correlates of this acute manifestation of CPP deposition. This is the first study to report higher odds for acute CPP crystal arthritis among males.

Introduction The concept of the critical shoulder angle (CSA) was introduced in 2013 with studies showing larger CSA is associated with rotator cuff tears (RCT) and smaller CSA with glenohumeral osteoarthritis. However, there is limited data on the impact of CSA, if any, on total shoulder arthroplasty (TSA) outcomes. Methods We conducted a matched case-control study using a shoulder arthroplasty registry from a US integrated healthcare system to identify patients who underwent primary elective anatomic TSA for the diagnosis of osteoarthritis from 2009-2018. 78 adult patients who underwent revision following the primary TSA due to glenoid component failure or rotator cuff tear comprised the case group. A control group of non-revised patients were identified from the same source population. Two controls were matched to each case by age, gender, body mass index, American Society of Anesthesiologists classification, surgeon who performed the index TSA, and post-TSA follow-up time. The relationships between revision and CSA as measured on radiographs were analyzed as a 1:2 matched-pairs case-control study with use of multiple conditional multivariable logistic regression. Results Revised cases had a higher likelihood of a CSA ≥35° (odds ratio [OR]=2.41, 95% confidence interval [CI]=1.27-4.59). A higher likelihood of CSA ≥35° was observed for those revised for glenoid loosening (OR=4.58, 95% CI=1.20-17.50) and revised for rotator cuff tear (OR= 2.41, 95% CI=1.18-4.92) compared to non-revised controls. Every 5° increase in CSA had higher odds of overall revision (OR=1.62, 95% CI=1.18-2.21), glenoid loosening (OR=2.50, 95% CI=1.27-4.92), and rotator cuff tear (OR=1.51, 95% CI=1.07-2.14). Conclusions In a matched case-control study of primary anatomic TSA, individuals who were revised for aseptic glenoid loosening and superior cuff failure had a higher CSA compared to non-revised individuals. These data suggest that surgeons may consider utilizing reverse arthroplasty in cases of primary shoulder arthritis with a CSA of 35° or greater.

The prevalence of allergic disorders has been increasing globally, and it may be useful to identify the modifiable factors associated with it. Diet has been identified as one possible lifestyle factor implicated in the pathogenesis of allergic diseases. The goal of this study was to evaluate the associations between dietary patterns and the presence of allergies in a group of young women in eastern Iran. In all, 181 female students were enrolled. Screening for presence of allergic diseases, including allergic rhinitis (AR), asthma and eczema, was performed by an expert allergist. Information about dietary intake was collected using a validated 65-item food frequency questionnaire. Exploratory factor analysis was used to evaluate the relationships between food/nutrition variables. Serum immunoglobulin (Ig)E levels were significantly higher in the group in the third tertile (highest adherence) for a Western dietary pattern compared to the group in the first tertile (lowest adherence). The multivariate odds ratio for presence of allergic rhinitis (AR) was 2.5 (95% CI:1.1-5.1) for the highest compared to lowest tertile of the Western dietary pattern score. However, no significant relationship was found between a traditional dietary pattern and AR, asthma or eczema. Our findings indicate a potential role in the development of AR of the Western dietary pattern, which is characterized by high intake of dairy products, snacks, nuts and sugar. Since diet is a modifiable factor, the relationship between AR and a Western dietary pattern may have clinical implications, particularly in subjects with other risk factors for developing AR.

Background The use of surgical clips for athermal dissection of the lateral prostatic pedicles and ligation during pelvic lymph node dissection (PLND) while performing robotic-assisted radical prostatectomy (RARP) has been the gold standard. Clips are used to prevent thermal injury of the unmyelinated nerve fibers and lymphceles, respectively. Objective To compare oncological and functional outcomes of a new technique of clipless, lateral pedicle control and PLND with RARP with bipolar energy (RARP-bi) versus the standard RARP technique with clips (RARP-c). Design, setting, and participants A retrospective study was conducted among 338 men who underwent RARP between July 2018 and March 2020. Surgical procedure RARP-c versus RARP-bi. Measurements We prospectively collected data and retrospectively compared demographic, clinicopathological, and functional outcome data. Urinary as well as sexual function was assessed using the Expanded Prostate Cancer Index for Clinical Practice, and complications were assessed using Clavien-Dindo grading. Multivariable regression modeling was used to examine whether the technical approach of RARP-bi versus RARP-c was associated with positive surgical margins (PSMs) or sexual and urinary function scores. Results and limitations A total of 144 (43%) and 194 (57%) men underwent RARP-bi and RARP-c, respectively. Overall, there were no differences in functional and oncological outcomes between the two approaches. On multivariable regression analysis, the RARP-bi technique was not associated with significant differences in PSMs (odds ratio [OR] = 1.04, 95% confidence interval [CI] 0.6–1.8; p = 0.9), sexual function (OR = 0.4, 95% CI 0.1–1.5; p = 0.8), or urinary function (OR = 0.5, 95% CI 0.2–1.4; p = 0.2). The overall 30-d complication rates (12% vs 16%, p = 0.5) and bladder neck contracture rates (2.1% vs 3.6%, p = 0.5) were similar between the two groups. There was no difference in lymphocele complications (1.4% vs 0.52%, p = 0.58). All complications were of Clavien-Dindo grade I–II. Conclusions Despite the concerns for an increased risk of nerve injury secondary to the use of bipolar energy for prostatic pedicle dissection, we demonstrate that this technique is oncologically and functionally similar to the standard approach with surgical clips. There was no difference in complications or lymphocele formation for techniques with versus without clips. Patient summary We describe a modified technique for prostatic pedicle dissection during robotic-assisted radical prostatectomy, which utilizes bipolar energy and is associated with shorter operative time, without compromising functional or oncological outcomes.

The range of internal rotation sometimes deteriorates after reverse total shoulder arthroplasty; however, the underlying mechanisms remain unclear. This study aimed to investigate the association between sagittal spinal alignment and internal rotation deterioration after reverse total shoulder arthroplasty.We retrospectively reviewed 52 patients who underwent reverse total shoulder arthroplasty by a single surgeon between October 2014 and December 2018. The sagittal spine was radiographed, and the sagittal spinal alignment was evaluated based on 10 parameters (e.g. C7-HA: the distance between the plumb line from the center of the seventh cervical vertebral body and the center of the hip axis). We divided the patients into two groups, group A (internal rotation deterioration; 23 patients) and B (without internal rotation deterioration; 29 patients). Logistic regression analysis was performed to analyze the association between sagittal spinal alignment and internal rotation deterioration after reverse total shoulder arthroplasty, and a receiver operating characteristic curve was used to analyse the cutoff value of independent variables that was correlated with IR deterioration.Logistic regression analysis demonstrated the correlation between C7-HA and internal rotation deterioration (odds ratio, 1.95; 95% confidence interval, 1.33-2.84; P 0.001). The receiver operating characteristic curve suggested that when C7-HA was at least 2.44 cm, it was strongly correlated with deterioration of internal rotation (sensitivity, 91.3%; specificity, 93.1%; P 0.001; area under the curve, 0.938). Group A was significantly inferior to group B in not only internal rotation but also flexion and abduction.This study suggested that a remarkably positive value in C7-HA was a factor that was correlated with deterioration of internal rotation. In addition, the deformation of sagittal spinal alignment would impact on the range of motion after reverse total shoulder arthroplasty.

Background The beneficial effects of urban open green space on residential health had few investigations in Taiwan. Methods A total of 40,375 participants older than 30-year-old attended the health screening program during 2007–2009 in the Metropolitan area in the New Taipei City. We defined urban open green spaces (UOGS) if land use belongs to parks, green, plaza, public schools and sport venues. Small public urban open space (SPUOS) is defined as UOGS with area less than 1 hector and with at least three of the followings: vegetations, sport facilities and benches. Greenness is defined as the mean Normalized Difference Vegetation Index (NDVI). Air quality was accessed by land use regression model. Logistic regression model was used to calculate odds ratios of diseases for proximity to UOGS or greenness. Results We found that CKD was significantly associated with proximity to SPUOS. No relationship was found between proximity to UOGS or NDVI and overweight or diabetes. The adjusted odds ratio of CKD comparing distance to SPUOS >200 m and ≤200 m was 1.144 (95% CI, 1.059–1.237). The effect of open space on CKD was similar if we incorporated public schools to SPUOS. Greenness was not associated with CKD. Subgroups analyses revealed the effect of SPUOS on CKD was more prominent in health residents, including in those who never smoke, no hypertension, no diabetes and no hypertriglyceridemia. Conclusion Proximity to SPUOS or schools is associated with lower risk of CKD for adults living in the Metropolitan area in New Taipei City.

Background & Aims Chronic pancreatitis (CP) is associated with osteopathy (osteoporosis or osteopenia). However, existing literature is mostly limited to retrospective or administrative studies that have not clearly defined the prevalence and risk factors. Our aim was to identify patient- and disease-related associations with osteopathy in a prospective cohort study of CP. Methods We studied 282 subjects with definitive CP enrolled in the PROCEED study who had a baseline dual-energy X-ray absorptiometry (DXA) scan. Osteopenia and osteoporosis were defined using the lowest T-scores. Clinical data were collected using standardized case report forms. Comparisons were performed with a multivariate logistic regression model with forward selection to identify risk factors for osteopathy. Results The majority of subjects had osteopathy on DXA scan (56.0%; 17.0% osteoporosis; 39.0% osteopenia). Subjects with osteopathy had a higher prevalence of traumatic (40.0% vs 26.4%; P = .02) and spontaneous fractures (3.9% vs 0; P = .04). On multivariate analysis, older age (odds ratio [OR], 1.29 per 5 years; 95% confidence interval [CI], 1.15–1.45), female sex (OR, 3.08; 95% CI, 1.75–5.43), white race (OR, 2.68; 95% CI, 1.20–6.01), and underweight body mass index category (OR, 7.40; 95% CI, 1.56–34.99) were associated with higher probability of osteopathy. There were no significant associations between osteopathy and other patient and disease-related features of CP. Conclusion In the largest study of patients with CP who underwent DXA screening, the majority had osteopathy. There are overlapping risk factors with osteopathy in the general population, but the high prevalence in men and younger women supports the need for future investigations into the mechanisms of bone loss in CP.

OBJECTIVE To determine the effectiveness of a brief intervention in increasing influenza vaccination coverage compared with the usual advice in people who refuse it, and to record the main reasons for refusing to be vaccinated. METHOD A cluster randomized clinical trial was conducted in which the study population was individuals with high risk factors who initially had refused to be vaccinated against influenza. Professionals (doctors and nurses) who voluntarily accepted to participate were assigned randomly to the intervention group (brief intervention) and the control group (usual advice). RESULTS 57 professionals recruited 524 people who had previously declined the influenza vaccination (271 in the control group and 253 in the intervention group). Brief intervention showed its effectiveness with an odds ratio of 2.48 (1.61-3.82; p

We studied posttraumatic stress disorder (PTSD), a severe trauma-related mental disorder, and systemic lupus erythematosus (SLE) risk in a large, diverse population enrolled in Medicaid, a US government-sponsored health insurance program for low-income individuals.We identified SLE cases and controls among patients ages 18-65 years enrolled in Medicaid for ≥12 months in the 29 most populated US states from 2007 to 2010. SLE and PTSD case statuses were defined based on validated patterns of International Classification of Diseases, Ninth Revision codes. Index date was the date of the first SLE code. Controls had no SLE codes but had another inpatient or outpatient code on the index date and were matched 1:10 to cases by age, sex, and race. Conditional logistic regressions calculated odds ratios (ORs) and 95% confidence intervals (95% CIs) for the association of PTSD with incident SLE, adjusting for smoking, obesity, oral contraceptive use, and other covariates.A total of 10,942 incident SLE cases were matched to 109,420 controls. The prevalence of PTSD was higher in SLE cases, at 10.74 cases of PTSD per 1,000 person-years (95% CI 9.37-12.31) versus 7.83 cases (95% CI 7.42-8.27) in controls. The multivariable-adjusted OR for SLE among those with PTSD was 2.00 (95% CI 1.64-2.46).In this large, racially and sociodemographically diverse US population, we found patients with a prior PTSD diagnosis had twice the odds of a subsequent diagnosis of SLE. Studies are necessary to clarify the mechanisms driving the observed association and to inform possible interventions.

Background & Aims Colonoscopy quality indicators provide measurable assessments of performance, but significant provider-level variations exist. We performed a systematic review and meta-analysis to assess whether endoscopist specialty is associated with adenoma detection rate (ADR) — the primary outcome — or cecal intubation rate, adverse event rates, and post-colonoscopy colorectal cancer rates. Methods We searched EMBASE, Google Scholar, MEDLINE, and the Cochrane Central Registry of Controlled Trials from inception to December 14, 2020. Two reviewers independently screened titles and abstracts. Citations underwent duplicate full-text review, with disagreements resolved by a third reviewer. Data were abstracted in duplicate. The DerSimonian and Laird random effects model was used to calculate pooled odds ratios (ORs) with respective 95% confidence intervals (CIs). Risk of bias was assessed using Risk of Bias in Non-randomised Studies of Interventions. Results Of 11,314 citations, 36 studies representing 3,500,832 colonoscopies were included. Compared with colonoscopies performed by gastroenterologists, those by surgeons were associated with lower ADRs (OR, 0.81; 95% CI, 0.74–0.88) and lower cecal intubation rates (OR, 0.76; 95% CI, 0.63–0.92). Compared with colonoscopies performed by gastroenterologists, those by other (non-gastroenterologist, non-surgeon) endoscopists were associated with lower ADRs (OR, 0.91; 95% CI, 0.87–0.96), higher perforation rates (OR, 3.02; 95% CI, 1.65–5.51), and higher post-colonoscopy colorectal cancer rates (OR, 1.23; 95% CI, 1.14–1.33). Substantial to considerable heterogeneity existed for most analyses, and overall certainty in the evidence was low according to the Grading of Recommendations, Assessment, Development, and Evaluations framework. Conclusion Colonoscopies performed by surgeons or other endoscopists were associated with poorer quality metrics and outcomes compared with those performed by gastroenterologists. Targeted quality improvement efforts may be warranted.

The aim of the study was to determine whether tibiofemoral contact stress predicts risk for worsening knee pain over 84 ms in adults aged 50-79 yrs with or at elevated risk for knee osteoarthritis.Baseline tibiofemoral contact stress was estimated using discrete element analysis. Other baseline measures included weight, height, hip-knee-ankle alignment, Kellgren-Lawrence grade, and Western Ontario and McMaster Universities Osteoarthritis Index pain subscale. Logistic regression models assessed the association between baseline contact stress and 84-mo worsening of Western Ontario and McMaster Universities Osteoarthritis Index pain subscale.Data from the dominant knee (72.6% Kellgren-Lawrence grade 0/1 and 27.4% Kellgren-Lawrence grade ≥ 2) of 208 participants (64.4% female, mean ± SD body mass index = 29.6 ± 5.1 kg/m 2 ) were analyzed. Baseline mean and peak contact stress were 3.3 ± 0.9 and 9.4 ± 4.3 MPa, respectively. Forty-seven knees met the criterion for worsening pain. The highest tertiles in comparison with the lowest tertiles of mean (odds ratio [95% confidence interval] = 2.47 [1.03-5.95], P = 0.04) and peak (2.49 [1.03-5.98], P = 0.04) contact stress were associated with worsening pain at 84 mos, after adjustment for age, sex, race, clinic site, and baseline pain. Post hoc sensitivity analyses including adjustment for body mass index and hip-knee-ankle alignment attenuated the effect.These findings suggest that elevated tibiofemoral contact stress can predict the development of worsening of knee pain.

BackgroundLopinavir/ritonavir, lopinavir/ritonavir-interferon (IFN)-β-1a and hydroxychloroquine efficacy for COVID-19 have been evaluated, but detailed evaluation is lacking.ObjectiveTo determine the efficacy of lopinavir/ritonavir, lopinavir/ritonavir-IFN-β-1a, hydroxychloroquine or remdesivir for improving the clinical, virological outcomes in COVID-19 inpatients.DesignOpen-label, randomized, adaptive, controlled trial.SettingMulti-center trial with patients from France.Participants583 COVID-19 inpatients requiring oxygen and/or ventilatory supportInterventionStandard of care (SoC, control), SoC plus lopinavir/ritonavir (400 mg lopinavir and 100 mg ritonavir every 12h for 14 days), SoC plus lopinavir/ritonavir plus IFN-ß-1a (44 μg of subcutaneous IFN-ß-1a on days 1, 3, and 6), SoC plus hydroxychloroquine (400 mg twice on day 1 then 400 mg once daily for 9 days) or SoC plus remdesivir (200 mg intravenously on day 1 then 100 mg once-daily for hospitalization duration or 10 days).MeasurementsThe primary outcome was the clinical status at day 15, measured by the WHO 7-point ordinal scale. Secondary outcomes included SARS-CoV-2 quantification in respiratory specimens and safety analyses.ResultsAdjusted Odds Ratio (aOR) for the WHO 7-point ordinal scale were not in favor of investigational treatments: lopinavir/ritonavirversuscontrol, aOR 0.83, 95%CI, 0.55 to 1.26, P=0.39; lopinavir/ritonavir-IFN-β-1aversuscontrol, aOR 0.69, 95%CI, 0.45 to 1.04, P=0.08; hydroxychloroquineversuscontrol, aOR 0.93, 95%CI, 0.62 to 1.41, P=0.75. No significant effect on SARS-CoV-2 RNA clearance in respiratory tract was evidenced. Lopinavir/ritonavir-containing treatments were significantly associated with more SAE.LimitationsNot a placebo-controlled, no anti-inflammatory agents tested.ConclusionNo improvement of the clinical status at day 15 nor SARS-CoV-2 RNA clearance in respiratory tract specimens by studied drugs.

BACKGROUND: Previous research indicated that diabetes during pregnancy results in a more permeable placenta. Based on this data, we hypothesized that women with maternal diabetes were more likely to have infants who developed neonatal abstinence syndrome (NAS). PURPOSE: The purpose of the study was to examine the association between maternal diabetes and NAS in a cohort of women reporting substance use during pregnancy. METHODS: This study used data from a population-based cohort of all newborns born in 2017 and 2018 (N = 36,974) in the state of West Virginia and restricted the analysis to those infants with intrauterine substance exposure (14%, n = 5188). Multiple logistic regression was performed to analyze the adjusted relationship between maternal diabetes and NAS while controlling for maternal and infant covariates. RESULTS: Just over 28% of women with diabetes had an infant who developed NAS, whereas 34.8% of women without diabetes had an infant who developed NAS. The adjusted odds ratio of infants developing NAS born to women with diabetes was 0.70 (95% confidence interval: 0.51, 0.94) compared with those born to mothers without diabetes after controlling for covariates. Contrary to our hypothesis, the study suggests that maternal diabetes during pregnancy is associated with a decreased risk of an infant developing NAS. IMPLICATIONS FOR PRACTICE: Future research generating from this hypothesis may lead to potential implications for practice for infants born to mothers with substance use during pregnancy and diabetes. IMPLICATIONS FOR RESEARCH: More research should be conducted to investigate the relationship between glucose metabolism and NAS.

Background: Limited data on electronic cigarette prevalence, patterns and settings of use are available from several European countries. Methods: Within the TackSHS project, a face-to-face survey was conducted in 2017-2018 in 12 European countries (Bulgaria, England, France, Germany, Greece, Ireland, Italy, Latvia, Poland, Portugal, Romania and Spain). Overall, 11,876 participants, representative of the population aged ≥15 years in each country, provided information on electronic cigarette. Findings: 2·4% (95% C.I. 2·2-2·7) of the subjects (2·5% men and 2·4% women; 0·4% never, 4·4% current- and 6·5% ex-smokers) reported current use of electronic cigarette, ranging from 0.6% in Spain to 7·2% in England. Of the 272 electronic cigarette users, 52·6% were dual users (i.e., users of both electronic and conventional cigarettes) and 58·8% used liquids with nicotine. In all, 65·1% reported using electronic cigarette in at least one indoor setting where smoking is forbidden, in particular in workplaces (34·9%) as well as bars and restaurants (41·5%). Multivariable logistic regression analysis showed that electronic cigarette use was lower among older individuals (p for trend

A retrospective case-control study was conducted, to identify risk factors for loss of kidney transplant function or death among the Indigenous kidney transplant recipients, beyond the information available from Australia and New Zealand Dialysis and Transplant (ANZDATA) Registry. Methods Cases were defined as all Australian Indigenous kidney transplant recipients from 1st January 2005 to 31 December 2015 from the major hospitals in the Northern Territory (NT) and South Australia (SA) who experienced graft loss (including patient death) up to two-years post-transplant. Controls (matched 4:1) were defined as all Indigenous kidney transplant recipients during the same period with functioning transplants at two-years post-transplant operation. Matching was done on gender and diabetes status. Regression analysis adjusted for age was used for comparing cases and controls. Results There were 17 cases and 68 matched controls. Among cases, the odds ratio for more than one hospital admission episode (compared to ≤1 episode) in the two years pre-transplant period was 6.2 (95% CI, 1.2-32.5). However, there were no significant differences in the frequency of comorbidities at renal replacement therapy start, cardiovascular intervention pre-transplant, pre-transplant infection screening, age and gender of the donors, frequency of admission episodes where an infection was documented, the total length of inpatient stay or admission to intensive care unit during pre-transplant hospital admission between cases and controls. Conclusion Early graft loss was associated with a higher frequency of hospital admissions in the two-years pre-transplant period. In contrast, other measured factors in the pre-transplant period did not predict these adverse outcomes. This article is protected by copyright. All rights reserved.

Introduction initiation of breastfeeding is crucial in preventing newborn deaths and influences childhood nutrition. There was limited updated evidence regarding early initiation of breast-feeding practice and associated factors among the target population in the study area. Objective To assess initiation of breastfeeding practice and its associated factors among mothers who have infants less than six months of age in, North West Ethiopia, 2020. Methods The Community based quantitative cross-sectional study was conducted among 405 respondents in the stud area, then data would be entered and analyzed by using SPSS version 20 statistical packages. Bivariate and multivariable logistic regression model analysis would be done. Odds ratio with 95% confidence was computed to determine the level of significance-value less than 0.05 considered as significant. Result This study showed that 94.7% of mothers in Debre Tabor Town practiced initiation of breastfeeding for their infants within the Less Than 12 Months of age. In multivariable analysis I n f a n t S e x, Female [AOR (95% CI) = 0.068 (0.002, 1.659), and Age of Mother 20–24 years [AOR (95% CI) = 2.33 (0.030, 17.12)], 25–29 years ((AOR = 8.20 [(95% CI: 12.212, 22.189]), and 30–34 years (AOR = 4.48 [95% CI: 0.463, 15.478], Assists (Attend) during delivery, Doctor (AOR = 0.644 [95% CI: 0.041, 10.138]) and Encourage BF by religious father (AOR = 6.669 [(95% CI: 4.27, 8.895]) were remained significantly associated with the outcome variable with at 95% CI and P- value of Conclusion and Recommendation: The prevalence of EIBF among mother-infant pairs of less than 12 months in debre tabor town, Northwest, Ethiopia, was found to be high as compared to national and global infant and young child feeding guidelines. However; it shows improvement as compared with some previous studies in Ethiopia. I n f a n t s e x, age of mother, assists during delivery, and encourage BF by religious father were factors associated with outcome in the stud area.

BACKGROUND Orthopaedic surgery is one of the most competitive but least diverse surgical specialties, with ever-increasing academic achievements (such as test scores) shown by applicants. Prior research shows that white applicants had higher United States Medical Licensing Exam (USMLE) Step 1 and Step 2 Clinical Knowledge scores as well as higher odds of Alpha Omega Alpha status compared with Black, Hispanic, and other applicant groups. Yet, it still remains unknown whether differences in application metrics by race/ethnicity sufficiently explain the underrepresentation of certain racial or ethnic minority groups in orthopaedic residency programs. QUESTIONS/PURPOSES In this study, we sought to determine (1) the relative weight of academic variables for admission into orthopaedic residency, and (2) whether race and gender are independently associated with admission into an orthopedic residency. METHODS The Electronic Residency Application System (ERAS) data from the Association of American Medical Colleges (AAMC) and the National Board of Medical Examiners (NBME) of first-time MD applicants (n = 8966) for orthopaedic surgery residency positions in the United States and of admitted orthopaedic residents (n = 6218) from 2005 to 2014 were reviewed. This dataset is the first and most comprehensive of its kind to date in orthopaedic surgery. Academic metrics, such as USMLE Step 1 and Step 2 Clinical Knowledge scores, number of publications, Alpha Omega Alpha status, volunteer experiences, work experience, as well as race and gender, were analyzed using hierarchical logistic regression models. The first model analyzed the association of academic metrics with admission into orthopaedic residency. In the second model, we added race and gender and controlled for metrics of academic performance. To determine how well the models simulated the actual admissions data, we computed the receiver operating characteristics (ROC) including the area under curve (AUC), which measures the model's ability to simulate which applicants were admitted or not admitted, with an AUC = 1.0 representing a perfect simulation. The odds ratio and confidence interval of each variable were computed. RESULTS When only academic variables were analyzed in the first model, Alpha Omega Alpha status (odds ratio 2.12 [95% CI 1.80 to 2.50]; p < 0.001), the USMLE Step 1 score (OR 1.04 [95% CI 1.03 to 1.04]; p < 0.001), the USMLE Step 2 Clinical Knowledge score (OR 1.01 [95% CI 1.01 to 1.02]; p < 0.001), publication count (OR 1.04 [95% CI 1.03 to 1.05]; p < 0.001), and volunteer experience (OR 1.03 [95% CI 1.01 to 1.04]; p < 0.001) were associated with admissions into orthopaedics while work and research experience were not. This model yielded a good prediction of the results with an AUC of 0.755. The second model, in which the variables of race and gender were added to the academic variables, also had a good prediction of the results with an AUC of 0.759. This model indicates that applicant race, but not gender, is associated with admissions into orthopaedic residency. Applicants from Asian (OR 0.78 [95% CI 0.67 to 0.92]), Black (OR 0.63 [95% CI 0.51 to 0.77], Hispanic (OR 0.48 [95% CI 0.36 to 0.65]), or other race groups (OR 0.65 [95% CI 0.55 to 0.77]) had lower odds of admission into residency compared with white applicants. CONCLUSION Minority applicants, but not women, have lower odds of admission into orthopaedic surgery residency, even when accounting for academic performance metrics. Changes in the residency selection processes are needed to eliminate the lower admission probability of qualified minority applicants in orthopaedic residency and to improve the diversity and inclusion of orthopaedic surgery. Changes including increasing the diversity of the selection committee, bias training, blinding applications before review, removal of metrics with history of racial disparities from an interviewer's candidate profile before an interview, and use of holistic application review (where an applicants' experiences, attributes, and academic metrics are all considered) can improve the diversity landscape in training. In addition, cultivating an environment of inclusion will be necessary to address these long-standing trends in orthopaedic surgery. CLINICAL RELEVANCE Race, but not gender, is associated with the odds of acceptance into orthopaedic surgery residency despite equivalent academic metrics. Changes in residency selection processes are suggested to eliminate the lower admission probability of qualified minority applicants into orthopaedic residency and to improve the diversity and inclusion of orthopaedic surgery.
