Missed Visits Predict Recurrence in Idiopathic Clubfoot.

BACKGROUND: Congenital talipes equinovarus, also known as "clubfoot," is a common congenital deformity. While reported relapse rates vary widely, relapse continues to be a common problem faced in the treatment of this condition. The objective of this study is to assess relationships between demographic/socioeconomic factors, follow-up, and rates of relapse in our population of clubfoot patients. METHODS: Retrospective chart review was conducted for patients undergoing treatment for idiopathic clubfoot from February 2012 to December 2022 at a tertiary children's hospital. Records were analyzed for follow-up adherence and recurrence in the Ponseti method, in addition to patient demographic and socioeconomic factors. Statistical analysis was performed to evaluate associations between recurrence, missed clinical visits, and demographic/socioeconomic factors of interest. RESULTS: Ninety-five patients were included in the study [74.7% male (N=71) and 25.2% female (N=24)]. A total of 64.2% (N=61) of patients developed recurrence during their treatment. Recurrence rates differed significantly by reported bracing noncompliance >1 month (35/46 vs. 26/49, P =0.019), having missed 1 or more clinical visits (38/61 vs. 8/34, P < 0.001), Medicaid or equivalent insurance type (41/56 vs. 20/39, P =0.028), non-white race (47/66 vs. 14/29, P =0.032, higher Social Deprivation Index score (56.13 vs. 41.06, P =0.019). Significant variables were analyzed using a multivariate logistic regression analysis (MVLR). After MVLR, having 1 or more missed clinical visits (OR 4.462, 95% CI: 1.549-12.856) remained significantly associated with increased rates of recurrence. Primary language preference and distance to the hospital were not associated with recurrence. CONCLUSIONS: Higher SDI scores, non-white race, Medicaid insurance, and missed clinical follow-up visits were all associated with increased rates of recurrence for clubfoot patients. Using an MVLR model, missed clinical follow-up visits remained independently associated with increased recurrence rates. LEVEL OF EVIDENCE: Level 2-retrospective, prognostic study.

Cardiovascular Disease in Total Knee Arthroplasty: An Analysis of Hospital Outcomes, Complications, and Mortality.

Background: Cardiovascular comorbidities have been identified as a significant risk factor for adverse outcomes following surgery. The purpose of this study was to investigate its prevalence and impact on postoperative outcomes, hospital metrics, and mortality in patients undergoing total knee arthroplasty (TKA). Our hypothesis was that patients with cardiovascular comorbidities would have worse outcomes, greater postoperative complication rates, and increased mortality compared to patients without cardiovascular disease. Methods: In this retrospective study, data from the National Inpatient Sample database from 2011 to 2020 were queried for patients who underwent TKA with preexisting cardiac comorbidities, including congestive heart failure (CHF), coronary artery disease (CAD), valvular dysfunction, and arrhythmia. Multivariate logistic regression analyses compared hospital metrics (length of stay, costs, and adverse discharge disposition), postoperative complications, and mortality rates while adjusting for demographic and clinical variables. All statistical analyses were performed using R studio 4.2.2 and Stata MP 17 and 18 with Python package. Results: A total of 385,585 patients were identified. Those with preexisting CHF, CAD, valvular dysfunction, or arrhythmias were found to be older and at higher risk of adverse outcomes, including prolonged length of stay, increased hospital charges, and increased mortality (p < 0.001). Additionally, all preexisting cardiac diagnoses led to an increased risk of postoperative myocardial infarction, acute kidney injury (AKI), and need for transfusion (p < 0.001). The presence of valvular dysfunction, arrhythmia, or CHF was associated with an increased risk of thromboembolic events (p < 0.001). The presence of CAD and valvular dysfunction was associated with an increased risk of urologic infection (p < 0.001). Conclusions: This study demonstrated that CHF, CAD, valvular dysfunction, and arrhythmia are prevalent among TKA patients and associated with worse hospital metrics, higher risk of perioperative complications, and increased mortality. As our use of TKA rises, a lower threshold for preoperative cardiology referral in older individuals and early preoperative counseling/intervention in those with known cardiac disease may be necessary to reduce adverse outcomes.

Nourishing the brain on deep space missions: nutritional psychiatry in promoting resilience.

The grueling psychological demands of a journey into deep space coupled with ever-increasing distances away from home pose a unique problem: how can we best take advantage of the benefits of fresh foods in a place that has none? Here, we consider the biggest challenges associated with our current spaceflight food system, highlight the importance of supporting optimal brain health on missions into deep space, and discuss evidence about food components that impact brain health. We propose a future food system that leverages the gut microbiota that can be individually tailored to best support the brain and mental health of crews on deep space long-duration missions. Working toward this goal, we will also be making investments in sustainable means to nourish the crew that remains here on spaceship Earth.

A Bibliometric Analysis of Ophthalmology Resident Research Productivity in the United States.

Background The extent and impact of ophthalmology resident scholarly output is not well known. The authors aim to quantify scholarly activity of ophthalmology residents during residency and assess what factors may be associated with greater research productivity of these residents. Material and Methods Ophthalmology residents who graduated in 2021 were identified from their respective program Web sites. Bibliometric data published by these residents between the beginning of their postgraduate year 2 (July 1, 2018) until 3 months after graduation (September 30, 2021) were captured through searches via PubMed, Scopus, and Google Scholar. The association of the following factors with greater research productivity numbers was analyzed: residency tier, medical school rank, sex, doctorate degree, type of medical degree, and international medical graduate status. Results We found 418 ophthalmology residents from 98 residency programs. These residents published a mean (±standard deviation [SD]) number of 2.68 ± 3.81 peer-reviewed publications, 2.39 ± 3.40 ophthalmology-related publications, and 1.18 ± 1.96 first-author publications each. The mean (±SD) Hirsch index (h-index) for this cohort was 0.79 ± 1.17. Upon multivariate analysis, we discovered significant correlations between both residency tier and medical school rank and all bibliometric variables assessed. Pairwise comparisons revealed that residents from higher tier programs had greater research productivity numbers than those from lower tier programs. Conclusion We obtained bibliometric standards for ophthalmology residents on a national scale. Residents who graduated from higher-ranked residency programs and medical schools possessed higher h-indices and published more peer-reviewed publications, ophthalmology-related articles, and first-author publications.

The Impact of Traumatic Brain Injury on Microbiome Composition: A Systematic Review.

Traumatic brain injuries (TBIs) are a significant health problem, impacting millions of people every year. Although emerging evidence suggests that the composition of the gut microbiome is altered after TBI, no systematic review has been published on this topic. The objective of the present systematic review is to analyze publications that evaluate the impact of TBI on gut microbiome composition. Research articles were pulled from seven databases. The systematic review was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. In order for publications to be eligible for this review, they had to (1) report on original human- or animal-subjects research, (2) evaluate the impact of TBI on the microbiome, and (3) be written in English and (4) be published in a peer-reviewed journal. Of the seven articles that met these criteria, one involved human participants, while the other six reported on experimental animal studies. All studies found changes in the gut microbiome following TBI, with similar changes in bacterial populations observed across studies. The limitations of these studies included the use of primarily male animals, limitations of 16 S rRNA gene sequencing, and small sample sizes. This review was also limited by the small pool of studies conducted in this area. In summary, changes in bacterial populations of the gut microbiome, specifically increases in proteobacteria and firmicutes, were observed across the studies. By evaluating the changes in the microbiome resulting from TBI, potential therapeutic interventions could be explored.
