The Prevalence of Hip Dysplasia on Radiographs for Adolescent Idiopathic Scoliosis.

BACKGROUND: During radiographic assessment of adolescent idiopathic scoliosis (AIS), upright images frequently capture the hip. The purpose of this study was to assess the prevalence of radiographic hip dysplasia on postero-anterior (PA) scoliosis radiographs, as defined as a lateral center edge angle (LCEA) ≤25 degrees. METHODS: All patients with upright PA scoliosis radiographs over a one-year study period at a single tertiary academic medical center (2020 to 2021) were included in the study. Radiographs containing the hip joints were annotated by 3 reviewers for left and right LCEA, and triradiate cartilage (TRC) status. Inter-rater reliability was determined among the 3 reviewers. RESULTS: Two hundred fifty patients {500 hips, 75.6% female, median age 14 [interquartile range (IQR)=3]} had PA scoliosis radiographs that captured the hip, which qualified for analysis. Seventy-four hips (14.8%) demonstrated evidence of dysplasia (LCEA ≤25 deg) in 55/250 patients (22%). The median LCEA was significantly lower in the dysplastic hip cohort (23.9 deg, IQR=4.8 deg), compared with those without dysplasia (33 deg IQR=7.3 deg; P =0.001). A higher percentage of dysplastic hip patients were female than male (72.7% vs. 27.3%). Patients with bilateral dysplasia had a similar LCEA ( 22.9 deg) [to those with unilateral dysplasia (22.9 deg left, 23.9 deg right, P =0.689)]. CONCLUSIONS: In a cohort of 250 AIS patients, 22% demonstrated evidence of hip dysplasia, as defined as an LCEA ≤2 degrees. The dysplastic patients were more likely to be female. Screening for hip symptomatology in AIS patients may be of benefit, considering the frequency of radiographic hip dysplasia in this population. LEVEL OF EVIDENCE: III. Type of Evidence: diagnostic.

Antibody-mediated rejection in pediatric kidney transplant recipients: A report from the Pediatric Nephrology Research Consortium.

BACKGROUND: Antibody-mediated rejection (AMR) is a major cause of kidney allograft loss. There is a paucity of large-scale pediatric-specific data regarding AMR treatment outcomes. METHODS: Data were obtained from 14 centers within the Pediatric Nephrology Research Consortium. Kidney transplant recipients aged 1-18 years at transplant with biopsy-proven AMR between 2009 and 2019 and at least 12 months of follow-up were included. The primary outcome was graft failure or an eGFR <20 mL/min/1.73 m2 at 12 months following AMR treatment. AMR treatment choice, histopathology, and DSA class were also examined. RESULTS: We reviewed 123 AMR episodes. Median age at diagnosis was 15 years at a median 22 months post-transplant. The primary outcome developed in 27.6%. eGFR <30 m/min/1.73 m2 at AMR diagnosis was associated with a 5.6-fold higher risk of reaching the composite outcome. There were no significant differences in outcome by treatment modality. Histopathology scores and DSA class at time of AMR diagnosis were not significantly associated with the primary outcome. CONCLUSIONS: In this large cohort of pediatric kidney transplant recipients with AMR, nearly one-third of patients experienced graft failure or significant graft dysfunction within 12 months of diagnosis. Poor graft function at time of diagnosis was associated with higher odds of graft failure.

Appropriateness of recommendations for surveillance colonoscopy after polypectomy - a comparison of adherence to the 2012 and 2020 USMSTF guidelines.

Background: Screening colonoscopy detects precancerous polyps, which when resected, prevents colon cancer. Recommendations for surveillance colonoscopy after polypectomy are based on the U.S. Multi-Society Task Force guidelines (USMSTF). Aim: to examine provider recommendations based on 2012 and 2020 USMSTF guidelines. Methods: A prospective analysis was performed to examine provider recommendations for index screening and surveillance colonoscopy from March 2022 to January 2023. Procedures with unknown histology or unsatisfactory bowel preparation were excluded. We recorded polyp morphology, histology, and subsequent recommendations made by endoscopists, to compare to the USMSTF guidelines. Results: 241 patients were included, with 371 endoscopies reviewed. For index screening colonoscopies, 86%, performed between 2012 and 2020, adhered to 2012 guidelines, while 71%, performed after 2020, adhered to the 2020 guidelines. For surveillance colonoscopies, 62% from 2012 and 2020, and 50% after 2020, adhered to the 2012 and 2020 guidelines, respectively (P < 0.001). For polyp types, recommendations after index colonoscopies showed low-risk adenoma (LRA) had 88% adherence to 2012 guidelines versus 73% adherence to 2020 guidelines. For surveillance colonoscopies, LRA had 73% adherence to 2012 guidelines versus 42% adherence to 2020 guidelines (P < 0.001). Recommendations after index colonoscopy showed high-risk adenoma (HRA) had 79% adherence to 2012 guidelines versus 63% adherence to 2020 guidelines. For surveillance colonoscopies, HRA had 88% adherence to the 2012 guidelines versus 69% adherence to 2020 guidelines (P < 0.001). Conclusions: Adherence declined for the introduction of 2020 guidelines and was poorer after 2nd surveillance exams. Increasing the evidence for interval recommendations may increase guideline adherence.

Delay in post-endoscopic refeeding in patients with upper GI bleeding leads to increased hospital length of stay.

BACKGROUND: Patients with acute upper gastrointestinal bleeding (UGIB) are made NPO prior to endoscopy. It is standard practice in those found to have low risk lesions to immediately resume a usual diet. Here, we evaluated refeeding practices in hospitalized patients with UGIB after endoscopy. METHODS: In this retrospective single-center cross-sectional study, we examined patients over the age of 18 with acute UGIB and low risk or no endoscopic lesion(s). Appropriate refeeding was categorically defined as resuming normal diet ≤ 4 h post-endoscopy. RESULTS: Of 230 patients (mean age, 62 years; 57% female) with acute UGIB and low-risk lesions or no lesion(s), 96 [41% (95% CI: 35% to 48%)] received their usual diet within 4 h after EGD. For the remaining 134 patients, refeeding was delayed on average from 13 (NPO until regular diet) to 31 (NPO until liquid diet, then regular diet) hours. Baseline clinical features were identical in patients who received their regular diet within 4 h after EGD and those who did not. Hospital length of stay was shorter in patients receiving usual diets promptly (5.3 days vs. 6.4 days, p = 0.03). Patients in an ICU at the time of their endoscopy had a statistically significantly higher probability of not being refed appropriately [OR 2.371, 95% CI 1.191-4.722). CONCLUSIONS: Inappropriate dietary restrictions are frequent in patients with UGIB caused by low risk lesions. This delay in refeeding leads to increased length of hospital stay - suggesting that appropriate refeeding is an opportunity to improve patient care.

Diagnostic utility of CT angiography compared with endoscopy in patients with acute GI hemorrhage.

BACKGROUND AND AIMS: Because it is minimally invasive, CT angiography (CTA) has emerged as an attractive diagnostic tool for investigation of acute GI hemorrhage. METHODS: This study examined patients with acute GI bleeding who underwent CTA. RESULTS: CTA was the initial diagnostic examination in 177 patients, identifying upper and lower GI bleeding lesions in 16 and 27 patients, respectively. In 103 patients with an initial negative CTA, 78 had endoscopy (32 EGD and 46 colonoscopy/flexible sigmoidoscopy), of whom 52 (67%) had a bleeding lesion identified, including 23 with a high-risk bleeding lesion requiring therapy. Peptic ulcer disease and diverticular bleeding were the most commonly identified bleeding lesions. With endoscopy as a criterion standard, the sensitivity of CTA for the detection of a source of GI bleeding was 20%. CONCLUSIONS: CTA has very poor sensitivity for identification of a GI bleeding source or lesion, suggesting that CTA should not be used as an initial diagnostic test.

Same Day Discharge After Mastectomy and Immediate Implant-Based Breast Reconstruction: A Retrospective Cohort Comparison Using the National Surgical Quality Improvement Program Database.

INTRODUCTION: Currently, overnight admission after immediate implant-based breast reconstruction (IBR) is the standard of care. Our study aims to analyze the safety, feasibility, and outcomes of immediate IBR with same-day discharge as compared with the standard overnight stay. METHODS: The 2015-2020 National Surgical Quality Improvement Program database was reviewed to identify all patients undergoing mastectomy with immediate IBR for malignant breast disease. Patients were stratified into study (patients discharged day of surgery) and control (patients admitted after surgery) groups. Patient demographics, comorbidities, surgical characteristics, implant type, wound complications, readmission, and reoperation rates were collected and analyzed. Univariate and multivariate logistic regression was used to determine independent predictors of same-day discharge versus admission. In addition, Pearson χ2 test was used for comparison of proportions and t test was used for continuous variables unless distributions required subsequent nonparametric analyses. Statistical significance was defined as a P value less than 0.05. RESULTS: A total of 21,923 cases were identified. The study group included 1361 patients discharged same day and the control group included 20,562 patient s admitted for average of 1.4 days (range, 1-86). Average age was 51 years for both groups. Average body mass index for the study group 27 and 28 kg/m2 for the control group, respectively. Total wound complication rates were similar (4.5% study, 4.3% control, P = 0.72). Reoperation rates were lower with same-day discharge (5.7% study, 6.8% control, P = 0.105), though not statistically significant. However, same-day discharge patients had a significantly lower readmission rate compared with the control (2.3% study, 4.2% control, P = 0.001). CONCLUSION: National Surgical Quality Improvement Program data analysis over a 6-year period reveals that immediate IBR with same-day discharge is associated with a significantly lower readmission rate when compared with the standard overnight stay. The comparable complication profiles show that immediate IBR with same-day discharge is safe, potentially benefiting both patients and hospitals.

Substrate Imaging Before Catheter Ablation of Ventricular Tachycardia: Risk Prediction for Acute Hemodynamic Decompensation.

BACKGROUND: The PAINESD (Pulmonary disease, Age, Ischemic cardiomyopathy, NYHA functional class, Ejection fraction, Storm, Diabetes mellitus) risk score has been validated as a predictor of periprocedural acute hemodynamic decompensation (AHD) in patients undergoing ventricular tachycardia (VT) ablation. Whether the addition of total scar volume (TSV) determined by preprocedure computed tomography imaging provides additional risk stratification has not been previously investigated. OBJECTIVES: The purpose of this study was to evaluate the impact of TSV on the risk of AHD and its adjunctive benefit to the PAINESD score newly modified as Pulmonary disease, Age, Ischemic cardiomyopathy, NYHA class, Ejection fraction, Storm, Scar volume, Diabetes mellitus (PAINES2D) based on the addition of scar volumes. METHODS: This was a retrospective analysis of all index VT ablations at a quaternary care center from 2017 to 2022. Associations between TSV and AHD were evaluated among patients with structural heart disease. RESULTS: Among 61 patients with TSV data, 13 (21%) had periprocedural AHD. TSV and PAINESD were independently associated with AHD risk. Both TSV and PAINESD were associated with AHD (P = 0.016 vs P = 0.053, respectively). The highest TSV tertile (≥37.30 mL) showed significant association with AHD (P = 0.018; OR: 4.80) compared to the other tertiles. The PAINESD and PAINES2D scores had significant impact on AHD (P = 0.046 and P = 0.010, respectively). The PAINES2D score had a greater impact on AHD compared to PAINESD (area under the curve: 0.73; P = 0.011; 95% CI: 0.56-0.91 and area under the curve: 0.67; P = 0.058; 95% CI: 0.49-0.85, respectively). CONCLUSIONS: Addition of TSV to a modified PAINESD score, PAINES2D, enhances risk prediction of AHD. Further prospective study is needed to assess benefit in various cardiomyopathy populations undergoing VT ablation.

BMI, physical activity, and breast cancer subtype in white, black, and Sea Island breast cancer survivors.

Higher BMI, lower rates of physical activity (PA), and hormone receptor-negative breast cancer (BC) subtype are associated with poorer BC treatment outcomes. We evaluated the prevalence of high BMI, low PA level, and BC subtype among survivors with white/European American (EA) and African American (AA) ancestry, as well as a distinct subset of AAs with Sea Island/Gullah ancestry (SI). We used the South Carolina Central Cancer Registry to identify 137 (42 EAs, 66 AAs, and 29 SIs) women diagnosed with BC and who were within 6-21 months of diagnosis. We employed linear and logistic regression to investigate associations between BMI, PA, and age at diagnosis by racial/ethnic group. Most participants (82%) were overweight/obese (P=0.46). BMI was highest in younger AAs (P=0.02). CDC PA guidelines (≥150min/week) were met by only 28% of participants. The frequency of estrogen receptor (ER)-negative BC subtype was lower in EAs and SIs than in AAs (P<0.05). This is the first study to identify differences in obesity and PA rates, and BC subtype in EAs, AAs, and SIs. BMI was higher, PA rates were lower, and frequency of ER-negative BC was higher in AAs as compared to EAs and SIs. This study highlights the need to promote lifestyle interventions among BC survivors, with the goal of reducing the likelihood of a BC recurrence. Integrating dietary and PA interventions into ongoing survivorship care is essential. Future research could evaluate potential differential immune responses linked to the frequency of triple negative BC in AAs.

Advanced glycation end products are elevated in estrogen receptor-positive breast cancer patients, alter response to therapy, and can be targeted by lifestyle intervention.

PURPOSE: Lifestyle factors associated with personal behavior can alter tumor-associated biological pathways and thereby increase cancer risk, growth, and disease recurrence. Advanced glycation end products (AGEs) are reactive metabolites produced endogenously as a by-product of normal metabolism. A Western lifestyle also promotes AGE accumulation in the body which is associated with disease phenotypes through modification of the genome, protein crosslinking/dysfunction, and aberrant cell signaling. Given the links between lifestyle, AGEs, and disease, we examined the association between dietary-AGEs and breast cancer. METHODS: We evaluated AGE levels in bio-specimens from estrogen receptor-positive (ER+) and estrogen receptor-negative (ER-) breast cancer patients, examined their role in therapy resistance, and assessed the ability of lifestyle intervention to reduce circulating AGE levels in ER+ breast cancer survivors. RESULTS: An association between ER status and AGE levels was observed in tumor and serum samples. AGE treatment of ER+ breast cancer cells altered ERα phosphorylation and promoted resistance to tamoxifen therapy. In a proof of concept study, physical activity and dietary intervention was shown to be viable options for reducing circulating AGE levels in breast cancer survivors. CONCLUSIONS: There is a potential prognostic and therapeutic role for lifestyle derived AGEs in breast cancer. Given the potential benefits of lifestyle intervention on incidence and mortality, opportunities exist for the development of community health and nutritional programs aimed at reducing AGE exposure in order to improve breast cancer prevention and treatment outcomes.

Interventions Promoting Physical Activity in African American Women: An Integrative Review.

BACKGROUND: Physical inactivity significantly impacts mortality worldwide. Physical inactivity is a modifiable risk factor for obesity, diabetes, cardiovascular disease, and other chronic conditions. African American women in the United States have the highest rates of physical inactivity when compared with other gender/ethnic groups. A paucity of research promoting physical activity (PA) in African American women has been previously identified. The purpose of this review was to identify intervention strategies and outcomes in studies designed to promote PA in African American women. METHODS: Interventions that promoted PA in African American women published between 2000 and May 2015 were included. A comprehensive search of the literature was performed in Health Source: Nursing/Academic Edition, PsycINFO, CINAHL Complete, and MEDLINE Complete databases. Data were abstracted and synthesized to examine interventions, study designs, theoretical frameworks, and measures of PA. RESULTS: Mixed findings (both significant and nonsignificant) were identified. Interventions included faith-based, group-based, and individually focused programs. All studies (n = 32) included measures of PA; among the studies, self-report was the predominant method for obtaining information. Half of the 32 studies focused on PA, and the remaining studies focused on PA and nutrition. Most studies reported an increase in PA or adherence to PA. This review reveals promising strategies for promoting PA. CONCLUSIONS: Future studies should include long-term follow-up, larger sample sizes, and objective measures of PA. Additional research promoting PA in African American women is warranted, particularly in studies that focus on increasing PA in older African American women.

Screening for Physical Activity and Cardiometabolic Risk Factors Among Rural African-American Women.

Physical inactivity can have major implications for cardiovascular disease and diabetes, which are leading causes of morbidity among African-American women. Recruiting in rural populations can present challenges and strategies that work in one community but may not be successful in another community. This study examined the feasibility, acceptability, and implementation of community-based screening using an abbreviated Racial and Ethnic Approaches to Community Health (REACH) Risk Factor self-report survey in a geographic region where these data were previously unavailable. Participants (N = 32) included African-American/Black women, 21 years of age or older, who attended health screening events in a rural county in South Carolina. Findings from this study demonstrated the feasibility of community-based cardiometabolic risk screenings using an abbreviated REACH Risk Factor survey and linking participants to follow-up primary care. Findings also provide insight into recruitment strategies in this geographic region.

Effective weight-loss using an e-health delivered physical activity and dietary intervention: A federal credit union pilot study.

BACKGROUND/OBJECTIVE: This pilot study investigated the effectiveness of a distance-based e-health program delivered across multiple rural Federal Credit Union worksites that focused on physical activity and dietary education. Program design and implementation were based on the premises of Social Impact Theory (SIT). METHODS: A sample of fifty-four participants (47 white. 7 black) aged 24 to 58 across different worksite locations completed 10 weeks of e-health delivered physical activity and dietary intervention. Pre to post weight changes were examined as a primary outcome. RESULTS: The findings showed that regardless of worksite location, participants on average reduced their weight by 10.13 lbs if they completed both the exercise and lunch and learn components of the study compared to a decrease of 2.73 lbs for participants who chose not to engage in the exercise related activities. Participant dropout from either group was less than four percent. CONCLUSIONS: The results of this study show the beneficial influence of physical activity integration using SIT upon distance programs targeting weight loss. In addition, the high adherence and weight loss success show promise and demonstrates the potential for e-health delivered exercise and lifestyle interventions. Further replication of results via additional randomized controlled trials is needed.
