Factors Influencing Primary Care Career Choice: A Multi-Institutional Cross-sectional Survey of Internal Medicine Primary Care Residency Graduates.

BACKGROUND: Although primary care is associated with population health benefits, the supply of primary care physicians continues to decline. Internal medicine (IM) primary care residency programs have produced graduates that pursue primary care; however, it is uncertain what characteristics and training factors most affect primary care career choice. OBJECTIVE: To assess factors that influenced IM primary care residents to pursue a career in primary care versus a non-primary care career. DESIGN: Multi-institutional cross-sectional study. PARTICIPANTS: IM primary care residency graduates from seven residency programs from 2014 to 2019. MAIN MEASURES: Descriptive analyses of respondent characteristics, residency training experiences, and graduate outcomes were performed. Bivariate logistic regression analyses were used to assess associations between primary care career choice with both graduate characteristics and training experiences. KEY RESULTS: There were 256/314 (82%) residents completing the survey. Sixty-six percent of respondents (n = 169) practiced primary care or primary care with a specialized focus such as geriatrics, HIV primary care, or women's health. Respondents who pursued a primary care career were more likely to report the following as positive influences on their career choice: resident continuity clinic experience, nature of the PCP-patient relationship, ability to care for a broad spectrum of patient pathology, breadth of knowledge and skills, relationship with primary care mentors during residency training, relationship with fellow primary care residents during training, and lifestyle/work hours (all p < 0.05). Respondents who did not pursue a primary care career were more likely to agree that the following factors detracted them from a primary care career: excessive administrative burden, demanding clinical work, and concern about burnout in a primary care career (all p < 0.05). CONCLUSIONS: Efforts to optimize the outpatient continuity clinic experience for residents, cultivate a supportive learning community of primary care mentors and residents, and decrease administrative burden in primary care may promote primary care career choice.

Intravenous immunoglobulin for treatment of hospitalized COVID-19 patients: an evidence mapping and meta-analysis.

BACKGROUND: The clinical efficacy and safety of intravenous immunoglobulin (IVIg) treatment for COVID-19 remain controversial. This study aimed to map the current status and gaps of available evidence, and conduct a meta-analysis to further investigate the benefit of IVIg in COVID-19 patients. METHODS: Electronic databases were searched for systematic reviews/meta-analyses (SR/MAs), primary studies with control groups, reporting on the use of IVIg in patients with COVID-19. A random-effects meta-analysis with subgroup analyses regarding study design and patient disease severity was performed. Our outcomes of interest determined by the evidence mapping, were mortality, length of hospitalization (days), length of intensive care unit (ICU) stay (days), number of patients requiring mechanical ventilation, and adverse events. RESULTS: We included 34 studies (12 SR/MAs, 8 prospective and 14 retrospective studies). A total of 5571 hospitalized patients were involved in 22 primary studies. Random-effects meta-analyses of very low to moderate evidence showed that there was little or no difference between IVIg and standard care or placebo in reducing mortality (relative risk [RR] 0.91; 95% CI 0.78-1.06; risk difference [RD] 3.3% fewer), length of hospital (mean difference [MD] 0.37; 95% CI - 2.56, 3.31) and ICU (MD 0.36; 95% CI - 0.81, 1.53) stays, mechanical ventilation use (RR 0.92; 95% CI 0.68-1.24; RD 2.8% fewer), and adverse events (RR 0.98; 95% CI 0.84-1.14; RD 0.5% fewer) of patients with COVID-19. Sensitivity analysis using a fixed-effects model indicated that IVIg may reduce mortality (RR 0.76; 95% CI 0.60-0.97), and increase length of hospital stay (MD 0.68; 95% CI 0.09-1.28). CONCLUSION: Very low to moderate certainty of evidence indicated IVIg may not improve the clinical outcomes of hospitalized patients with COVID-19. Given the discrepancy between the random- and fixed-effects model results, further large-scale and well-designed RCTs are warranted.

Associations among dietary 1-carbon metabolism nutrients, genetic risk, and Alzheimer disease: a prospective cohort study.

BACKGROUND: The associations between 1-carbon metabolism (OCM) nutrients (methionine, folate, vitamin B-6, and vitamin B-12) and Alzheimer disease (AD) remains inconclusive. OBJECTIVES: This study aimed to investigate the association of dietary OCM nutrients with subsequent risk of AD and further assess whether participants with high genetic risk for AD might benefit from dietary OCM nutrients. METHODS: We analyzed data from 192,214 participants who completed at least one 24-h dietary questionnaire and had no previous history of AD based on the UK Biobank. Nutrients intake was calculated using McCance and Widdowson's The Composition of Food and USDA's Food and Nutrient Database for Dietary Studies. Cox proportional models with restricted cubic splines were applied to explore the associations. RESULTS: Over a median follow-up of 13.35 y, 959 cases of AD (41 early-onset cases and 918 late-onset cases) were identified. Compared with those in the low-intake OCM group (quartile 1), participants in the high-intake OCM group (quartile 4) had reduced risk of developing AD. The corresponding hazard ratios (HRs) and 95% confidence intervals (CIs) for methionine, folate, vitamin B-6, and vitamin B-12 intake were 0.66 (0.54, 0.80), 0.71 (0.58, 0.87), 0.71 (0.59, 0.87), and 0.77 (0.64, 0.93), respectively. Similar associations were observed in late-onset AD. In early-onset AD, high methionine and vitamin B-12 intake were associated with 70% (HR: 0.30; 95% CI: 0.10, 0.86) and 71% (HR: 0.29; 95% CI: 0.09, 0.96) reduction in risk, respectively. Participants with low genetic risk and high OCM nutrients intake had >75% reduced AD risk compared with high-risk, low-intake participants. CONCLUSIONS: In this prospective cohort study, we found that higher intake of OCM nutrients is associated with reduced risk of AD. Participants with high genetic risk of AD are more likely to benefit from dietary OCM nutrients intake.

Cognitive behavioural therapy for functional abdominal pain disorders in children and adolescents: A systematic review of randomized controlled trials.

AIM: Although Cognitive behavioural therapy (CBT) potentially holds efficacy in addressing functional abdominal pain disorders (FAPDs) amongst children and adolescents, the persistent efficacy is uncertain. METHODS: We searched three databases to identify related randomized controlled trials (RCTs). Meta-analysis was performed using RevMan and Stata. Subgroup analyses were mainly conducted based on follow-up time. The GRADE approach was used to evaluate the certainty of the evidence. RESULTS: A total of 14 RCTs evaluating 858 patients were included. All RCTs were rated as having a high risk of bias. Compared with control groups, CBT was associated with improvement of general functional impairment (standardized mean difference (SMD) = -0.77, 95% CI [-1.12, -0.42], p < 0.05), higher treatment success (relative risk (RR) = 2.35, 95% CI [1.50, 3.69], p < 0.05), improvement of abdominal pain symptoms (SMD = -0.48, 95% CI [-0.73, -0.23], p < 0.05), QoL (SMD = 0.42, 95% CI [0.20, 0.64], p < 0.05), and psychological states (SMD = -0.95, 95% CI [-1.62, -0.27], p < 0.05). CONCLUSION: This meta-analysis provides low to moderate quality evidence that CBT could significantly improve clinical outcomes and QoL for children and adolescents with FAPDs with improvement persisting until short-term follow-up. However, there were discrepancies regarding CBT's effects at mid- and long-term follow-up across different outcomes. More high-quality and longer-duration studies are thus warranted to explore the effectiveness of CBT in the future. SYSTEMATIC REVIEW REGISTRATION ON PROSPERO: CRD42022369353.

Near-Peer Supervision in Primary Care: Bringing Teaching Teams From the Wards to the Clinic.

Background: Teaching near-peers yields numerous benefits to residents. Opportunities for near-peer teaching are typically restricted to hospital settings. Little is known about the educational potential of outpatient near-peer teaching. Objective: To describe Primary Care Teaching (PC Teach), a novel outpatient near-peer teaching experience for residents in a large, urban, internal medicine residency program; characterize its feasibility and acceptability; and evaluate changes in residents' self-reported confidence in outpatient teaching and attitudes toward teaching and primary care/outpatient medicine. Methods: In 2020-2021, following a didactic workshop, 43 postgraduate year 3 (PGY-3) residents at continuity clinics assigned to PC Teach completed a series of half-day sessions acting as preceptor to interns under attending supervision. Worksheets facilitated post-session feedback for residents and interns. Eighteen PGY-3s at nonparticipating clinics, who also completed the workshop, served as controls. We assessed process measures for feasibility and acceptability and analyzed resident attitudes using pre-post surveys. Results: Participating residents completed 2 to 8 sessions each. Post-intervention scores for confidence in outpatient teaching and attitudes toward teaching were greater, relative to pre-intervention group means, for intervention residents (median pre-post changes +0.60 [IQR 0.26, 1.26] and +0.46 [-0.04, 0.46], respectively) vs controls (-0.15 [-0.48, 0.85] and -0.36 [-0.86, 0.39]; between-group differences +0.75 [P=.03] and +0.82 [P=.02]). Changes in attitudes toward primary care/outpatient medicine did not differ significantly between intervention and control groups (+0.43 [-0.07, 0.68] and 0.04 [-0.58, 0.42]; between-group difference +0.39 [P=.12]). In multivariable analyses, odds of gains in confidence in outpatient teaching remained significantly larger for intervention residents vs controls. Conclusions: Implementing PC Teach with existing resources was feasible and acceptable, with program flexibility highlighted as a strength. Resident participation was associated with greater confidence in outpatient teaching.

The Effects of Oral Probiotic Supplementation in Postmenopausal Women with Overweight and Obesity: A Systematic Review and Meta-analysis of Randomized Controlled Trials.

Gut microbiota has been identified as a unique endocrine organ linked to the development of cardiovascular disease and other illnesses, especially deteriorated in overweight and obese postmenopausal women. The object of this systematic review and meta-analysis aimed to assess the effects of oral supplementation with probiotics for overweight and obese postmenopausal women. We performed a systematic search for randomized controlled trials (RCTs) from inception to April 2022 in MEDLINE, Embase, Cochrane Library, Web of Science, and ClinicalTrials.gov. We also performed a hand search by reviewing reference lists to identify trials. The risk of bias in individual studies was assessed with the Cochrane risk of bias tool for randomized trials (RoB). Two reviewers independently selected studies and collected data. There were 6 studies from 5 RCTs with 281 participants in this systematic review. Compared with the placebo, the probiotics supplementation group had reductions in insulin (MD - 4.20 IU/L (95% CI - 8.11 to - 0.30 IU/L), I2 = 54%), HOMA-IR (MD - 1.25 (95% CI - 2.49 to - 0.01), I2 = 50%), and TNF-α (MD - 0.12 pg/mL (95% CI - 0.22 to - 0.01 pg/mL), I2 = 44%). Improvements were also shown in body adiposity and lipid profile, but these effects were nonsignificant. In addition to body adiposity and cardiovascular risk markers, one trial showed the administration of probiotics also had an effect on iron metabolism. In conclusion, probiotics have a potential benefit on glucose metabolism and inflammatory process in overweight and obese postmenopausal women, but this effect is mild. It demonstrates that oral probiotics supplementation can be a complementary treatment for improving the fitness of postmenopausal women with overweight and obesity.
