ABSTRACTObjectiveTo study the association between dietary patterns and subgingival microbiota.MethodsParticipants (n = 651) who were enrolled in the Oral Infections, Glucose Intolerance, and Insulin Resistance Study (ORIGINS) with subgingival plaque sampling (n = 890 plaques) and a dietary assessment were included. 16S rRNA gene amplicon sequences of subgingival plaque from sites with either probing depth <4 or ≥4 mm were processed separately and used to obtain α‐diversity metrics (Faith, Shannon, Simpson, Observed) and taxa ratios (Red Complex to Corynebacterium [RCLR], Treponema to Corynebacterium [TCLR], and Treponema to Neisseria [TNLR]). Food frequency questionnaires (FFQs) were processed to calculate Alternate Healthy Eating Index (AHEI) and A Priori Diet Quality Score (APDQS) scores. Mixed regression models examined the mean levels of microbial metrics across quartiles of diet quality. Means ± standard errors are reported along with p‐values.ResultsIn multivariable models assessing the association between diet scores and α‐diversity metrics, higher AHEI values were significantly associated with lower Faith (p‐value = 0.01) and Observed (p‐value = 0.04) diversity values; similar findings were observed for APDQS (p‐value = 0.01, p‐value = 0.04). In multivariable models assessing the association between diet scores (AHEI and APDQS) and taxa ratios (RCLR, TCLR and TNLR), as the AHEI quartile increased, all taxa ratios decreased significantly as follows: −1.06 ± 0.093 in Q1 to −1.34 ± 0.099 in Q4 (RCLR), −0.43 ± 0.077 in Q1 to −0.64 ± 0.083 in Q4 (TCLR) and −0.09 ± 0.083 in Q1 to −0.38 ± 0.089 in Q4 (TNLR), respectively. In contrast, as the APDQS quartiles increased, only TNLR decreased significantly from −0.08 ± 0.085 in Q1 to −0.34 ± 0.091 in Q4.ConclusionDiets rich in fruits, vegetables, whole grains and other nutritionally rich plant foods are associated with lower oral microbial diversity and favourable ratios of pathogenic to commensal microbiota.

Background: The number of hip arthroscopies performed in the United States has grown significantly over the past several decades, with evolving indications and emerging techniques. Purposes: To (1) examine the evolution of hip arthroscopy at 3 tertiary referral centers between 1988 and 2022 and (2) quantify trends in patient demographics and procedures performed. Study Design: Case series; Level of evidence, 4. Methods: A retrospective analysis was performed of all patients undergoing hip arthroscopy at 3 academic centers between 1988 and 2022. Demographic data were collected using standardized forms and operative notes, and intraoperative images were manually reviewed for each patient to determine the specific procedures performed at the time of the hip arthroscopy. Surgical procedures were plotted over time to evaluate trends. Patients were divided into 3 time periods for comparison: early hip arthroscopy from 1988 to 2008, 2009 (the time of the first labral repair in our cohort) to 2015, and 2016 to 2022. Results: A total of 3000 patients (age, 35.7 ± 13.8 years; age range, 10-89 years; female sex, 2109 (70.3%); body mass index, 27.4 ± 6.3 kg/m 2 ) underwent arthroscopic hip procedures between 1988 and 2022. The mean number of cases increased from a mean of 3.2 per year in 1988-2008 to 285.9 per year in 2016-2022 ( P < .001). Labral treatment at the time of primary hip arthroscopy evolved from 100% debridement and 0% repair in 1988-2008 to 5.0% debridement, 94.0% repair, and 1.0% labral reconstruction in 2016-2022 ( P < .001). Cam resection increased from 4.1% in 1988-2008 to 86.9% in 2016-2022 ( P < .001). By 2022, 45 out of 325 cases (13.8%) were revisions. The rate of capsular repair at the time of primary hip arthroscopy increased from 0.0% in 1988-2008 up to 81.0% in 2016-2022. Conclusion: There has been a significant growth of hip arthroscopy volumes as well as a significant transition from use as a tool for diagnosis and labral debridement to procedures restoring native anatomy including labral repair, cam resection, capsular repair, periacetabular osteotomy, and gluteal repair.

Background Randomized clinical trials (RCTs) are considered the gold standard for evaluating the efficacy of healthcare interventions. However, conflicts of interest (COIs) can compromise the scientific integrity in these trials. This study characterized COIs in RCTs on spinal cord stimulation for chronic pain, focusing on the prevalence, disclosure, and monetary value of COIs. Methods This cross-sectional study analyzed RCTs published from January 1, 2013 to July 27, 2023. Primary outcomes included the presence, disclosure, and monetary value of COIs, while secondary outcomes assessed the presence of direct/indirect COIs, sponsor access to data, and associations between COIs and select variables, including journal impact factor, publication year, and study outcomes. Results Of 38 RCTs, 30 (78.9%) reported COIs. On average, 35.6% of authors per RCT had at least one COI, with a mean of 0.7 COIs per author. The mean annual monetary value of COIs was US$41,157.83 per author per RCT. 29 RCTs (76.3%) had undisclosed COIs, with an average of 24.2% of authors per RCT having undisclosed COIs. Sponsor access to data was reported in 67.6% of RCTs. No associations were observed between the mean percentage of authors with COIs and the monetary value of COIs and select dependent variables (impact factor, publication year, and study outcomes). Conclusions A substantial majority of RCTs reported COIs with many authors having undisclosed conflicts, highlighting the need for stringent COI disclosure guidelines to maintain research integrity. Expanding COI registry systems globally and increasing non-industry funding are crucial steps toward enhancing transparency and reducing biases in medical research.

BACKGROUND AND OBJECTIVE There is limited research on screening for social determinants of health (SDOH) in hospitalized pediatric patients. In this article, we describe patient characteristics related to SDOH screening in the hospital setting and examine relationships with acute care metrics. METHODS This is a retrospective cohort study. From July 2020 to October 2021, a 14-question SDOH screener was administered to families of patients admitted or transferred to the hospital medicine service. Information was collected regarding screen results, demographics, patient comorbidities, patient complexity, and acute care metrics. Unadjusted and multivariable analyses were performed using generalized estimation equation logistic regression models. RESULTS Families in 2454 (65%) patient encounters completed SDOH screening, with ≥1 need identified in 662 (27%) encounters. Families with significant odds for positive screening results in a multivariable analysis included primary language other than English (odds ratio [OR] 4.269, confidence interval [CI] 1.731–10.533) or Spanish (OR 1.419, CI 1.050–1.918), families identifying as “Black” (OR 1.675, CI 1.237–2.266) or Hispanic (OR 1.347, CI 1.057–1.717) or having a child on the complex care registry (OR 1.466, CI 1.120–1.918). A positive screening result was not associated with increased length of stay, readmission, or 2-year emergency department or acute care utilization. CONCLUSIONS In hospitalized pediatric patients, populations at the greatest odds for positive needs include families with primary languages other than English or Spanish, those that identified as certain races or ethnicities, or those having a child on the complex care registry. A positive SDOH screening result in this study was not associated with an increase in length of stay, readmission, or acute care utilization.

Abstract Disclosure: A. Verma: None. F. Elli: None. S. Rao: None. M. Smith: None. A. Shapiro: None. C. Moshe: None. R. Chadha: None. Introduction: Pheochromocytomas are rare, neuroendocrine tumors derived from chromaffin cells of the neural crest, typically within the adrenal medulla. The pathophysiologic effect of primary concern is the uncontrolled release of catecholamines into the bloodstream, which carry risk for episodic hypertension, palpitations, and life-threatening crises. Preoperative preparation with drugs that block adrenergic receptors is utilized to improve hemodynamic oscillation force and surgical outcomes. Widely used premedication include alpha-blockers, beta-blockers, and calcium channel blockers. Despite adequate pretreatment, hemodynamic instability continues to evoke massive risk. The objective of this study was to assess the incidence of intraoperative hypertensive episodes in patients undergoing robotic assisted laparoscopic adrenalectomy. Methods: This study is an observational retrospective analysis of patients who underwent elective laparoscopic robotic-assisted adrenalectomies from February 2019 to April 2023. 17 patients total patients were included. Preoperative information included age, BMI, ASA physical classification, preoperative blockade regiment, and urine metanephrines. Intraoperative information included operation duration, tumor size, intraoperative anti-hypertensives, and hypertensive spikes defined as a SBP greater than 175 mmHg for 5 consecutive minutes. Data analysis was performed to obtain frequency counts (%), means (standard deviations), and median (range) as appropriate. Results: The mean age at the time of surgery was 57.12 ± 17.2 years. The majority of patients (76%) were ASA status class III. 7 of the 17 patients did not have active pheochromocytoma based on symptomatology, the incidental diagnoses being made by imaging and workup. The average tumor diameter was 3.90 ± 1.8, with a range of 2.0 - 8.0. Mean operative time was 153.76 ± 53.9 minutes. Preoperative urinary metanephrines were observed to have a mean of 1,248.44 ± 2,866.9 pg/mL. In terms of preoperative preparation, 65% of patients received Doxazosin, and 29% of patients received an alternative anti-hypertensive. Yet, 64.7% of patients were found to have at least 1 intraoperative hypertensive spike Conclusion: Despite premedication with anti-hypertensives, a significant percentage of patients experienced intraoperative hemodynamic instability. This emphasizes the importance of anesthesiologist preparation for intraoperative hypertension management to aggressively prevent hypertensive crises. In addition, it questions the routine use of alpha blockade for all cases preoperatively as has been suggested in certain studies, and whether or not it should be driven by other patient characteristics.
