Racial and ethnic disparities in access to total neoadjuvant therapy for rectal cancer.

BACKGROUND: Total neoadjuvant therapy has revolutionized the treatment of locally advanced rectal cancer and quickly become the new standard of care. Whether patients from all racial and ethnic groups have had equal access to these potential benefits, however, remains unknown. METHODS: We identified all adults diagnosed with locally advanced rectal cancer in California who underwent neoadjuvant chemotherapy and radiation from 2010 to 2020 using the California Cancer Registry. We used logistic regression to estimate the predicted probability of receiving total neoadjuvant therapy as opposed to traditional chemoradiotherapy for each racial and ethnic group and used a time-race interaction to evaluate trends in access to total neoadjuvant therapy over time. We also compared survival by racial and ethnic group and total neoadjuvant therapy status using Kaplan-Meier plots and Cox proportional hazards models. RESULTS: In total, 6,856 patients met inclusion criteria. Overall, 36.6% of patients received total neoadjuvant therapy in 2010 compared with 66.3% in 2020. Latino patients were significantly less likely than non-Latino White patients to undergo total neoadjuvant therapy ; however, there was no difference in the rate of growth in total neoadjuvant therapy over time between racial and ethnic groups. Non-Latino Black patients appeared to have lower risk-adjusted survival compared with non-Latino White patients, although not among patients who underwent total neoadjuvant therapy . CONCLUSION: Access to total neoadjuvant therapy has increased significantly over time in California with no apparent difference in the rate of growth between racial and ethnic groups. We found no evidence of racial or ethnic disparities in survival among patients treated with total neoadjuvant therapy, suggesting that increasing access to high-quality cancer care may also improve health equity.

Variance Decomposition of Racial and Ethnic Disparities in Colon Cancer.

This cohort study examines the hospital factors associated with disparities in access and quality of colon cancer care among Hispanic patients.

Disparities in Access, Quality, and Clinical Outcome for Latino Californians with Colon Cancer.

OBJECTIVE: To compare access, quality, and clinical outcomes between Latino and non-Latino White Californians with colon cancer. SUMMARY BACKGROUND DATA: Racial and ethnic disparities in cancer care remain understudied, particularly among patients who identify as Latino. Exploring potential mechanisms, including differential utilization of high-volume hospitals, is an essential first step to designing evidence-based policy solutions. METHODS: We identified all adults diagnosed with colon cancer between January 1, 2010 and December 31, 2020 from a statewide cancer registry linked to hospital administrative records. We compared survival, access (stage at diagnosis, receipt of surgical care, treatment at a high-volume hospital), and quality of care (receipt of adjuvant chemotherapy, adequacy of lymph node resection) between patients who identified as Latino and as non-Latino White. RESULTS: 75,543 patients met inclusion criteria, including 16,071 patients who identified as Latino (21.3%). Latino patients were significantly less likely to undergo definitive surgical resection (marginal difference [MD] -0.72 percentage points, 95% CI -1.19,-0.26), have an operation in a timely fashion (MD -3.24 percentage points, 95% CI -4.16,-2.32), or have an adequate lymphadenectomy (MD -2.85 percentage points, 95% CI -3.59,-2.12) even after adjustment for clinical and sociodemographic factors. Latino patients treated at high-volume hospitals were significantly less likely to die and more likely to meet access and quality metrics. CONCLUSIONS: Latino colon cancer patients experienced delays, segregation, and lower receipt of recommended care. Hospital-level colectomy volume appears to be strongly associated with access, quality, and survival--especially for patients who identify as Latino--suggesting that directing at-risk cancer patients to high-volume hospitals may improve health equity.

Nutrition and eating beliefs and behaviors among individuals with spinal cord injuries and disorders: Healthy or misconceived?

PURPOSE/OBJECTIVE: Nutrition knowledge, beliefs, and behaviors have important implications for managing and preventing chronic and injury-related secondary conditions in persons with spinal cord injuries and disorders (SCI/D). Yet, the unique dietary and nutritional needs and recommendations specific to individuals with SCI/D and their eating beliefs and behaviors have been understudied. Aim is to describe nutrition and eating beliefs and behaviors from the perspectives of individuals with SCI/D. RESEARCH METHOD/DESIGN: Descriptive qualitative design using in-depth semistructured interviews with a national sample of veterans with SCI/D (n = 33). Audio-recorded and transcribed verbatim transcripts were coded and analyzed using thematic analysis. RESULTS: Participants were male (61%), aged 29-84 years, and 55% had tetraplegia. Five key themes were identified: extreme fasting/caloric restriction, perceived healthy eating behaviors, perceived unhealthy eating behaviors, modified eating behaviors due to SCI/D-related symptoms, and food/preparation choices based on abilities/independence and access. CONCLUSIONS/IMPLICATIONS: Nutrition among veterans with SCI/D may be impacted by many factors, such as nutrition knowledge and beliefs/behaviors about "healthy" and "unhealthy" nutrition, fasting, caloric restriction, imbalanced intake of macro- and micronutrients, overconsumption relative to energy needs, injury-related secondary complications, postinjury body composition and function changes, impairments related to satiety and hunger signals, and difficulty in obtaining and preparing food. Study findings provide many areas that would benefit from intervention. Findings can be used to inform ideal nutrition and healthy eating beliefs and behaviors which are important because nutritional inadequacies can lead to diet-related diseases, may exacerbate SCI secondary conditions, and lead to poor overall health.

Why may patients with spinal cord injury be overlooked for obesity screening in the Veterans Health Administration? Qualitative research of the perspectives of patients and healthcare providers.

PURPOSE: We sought to describe factors influencing reduced rates of obesity screening for patients with spinal cord injury (SCI) in the United States Veterans Health Administration (VA) and to foster potential solutions. MATERIALS AND METHODS: Semi-structured interviews with healthcare providers and patients with SCI who were recruited nationally from diverse VAs. We performed rapid qualitative analysis using content analysis of interview data. RESULTS: There were 36 providers and 37 patients. We identified provider, patient, and system level barriers to obesity screening for individuals with SCI. Overarching barriers involved provider and patient perceptions that obesity screening is a low priority compared to other health conditions, and body mass index is of low utility. Other obesity screening barriers were related to measuring weight (i.e., insufficient equipment, unknown wheelchair weight, staffing shortages, measurement errors, reduced access to annual screening, insufficient time, patient preference not to be weighed) and measuring height (i.e., insufficient guidance and equipment to this population, measurement errors). CONCLUSIONS: Barriers to obesity screenings exist for patients with SCI receiving care in VA. Healthcare provider and patient interviews suggest possible solutions, including standardizing height and weight measurement processes, ensuring equipment availability in clinics, clarifying guidelines, and offering support to providers and patients.IMPLICATIONS FOR REHABILITATIONIndividuals with spinal cord injury (SCI) have higher rates of obesity, but are often overlooked for annual obesity screening, even in clinic settings designed to care for individuals with SCI.Results may help tailor guidelines/education for healthcare and rehabilitation providers offering them guidance for improving obesity screening for individuals with SCI by standardizing weight and height measurement and documentation. To facilitate this, findings highlight the need for resources, such as ensuring clinics have necessary equipment, and increasing patient access to support and equipment.Improving the provision of obesity screening for individuals with SCI is necessary to improve health outcomes and patient satisfaction with care.

Interaction between increasing body mass index and spinal cord injury to the probability of developing a diagnosis of nonalcoholic fatty liver disease.

Background: The prevalence of obesity and comorbidities is high in the population with spinal cord injury (SCI). We sought to determine the effect of SCI on the functional form of the relationship between body mass index (BMI) and risk of developing nonalcoholic fatty liver disease (NAFLD), and assess whether SCI-specific mapping of BMI to risk of developing NAFLD is needed. Methods: Longitudinal cohort study comparing Veterans Health Administration patients with a diagnosis of SCI to a 1:2 matched control group without SCI. The relationship between BMI and development of NAFLD at any time was assessed with propensity score matched Cox regression models; NAFLD development at 10-year with a propensity score matched logistic model. The positive predictive value of developing NAFLD at 10 years was calculated for BMI 19-45 kg/m2. Results: 14,890 individuals with SCI met study inclusion criteria, and 29,780 Non-SCI individuals in matched control group. Overall, 9.2% in SCI group and 7.3% in Non-SCI group developed NAFLD during the study period. A logistic model assessing the relationship between BMI and the probability of developing a diagnosis of NAFLD demonstrated that the probability of developing disease increased as BMI increased in both cohorts. The probability was significantly higher in the SCI cohort at each BMI threshold (p < 0.01), and increased at a higher rate compared with the Non-SCI cohort as BMI increased 19-45 kg/m2. Positive predictive value for developing a diagnosis of NAFLD was higher in the SCI group for any given BMI threshold from 19 kg/m2 to BMI 45 kg/m2. Conclusions: The probability of developing NAFLD is greater in individuals with SCI than without SCI, at every BMI level 19 kg/m2 to 45 kg/m2. Individuals with SCI may warrant a higher level of suspicion and closer screening for NAFLD. The association of SCI and BMI is not linear.

The impact of the COVID-19 pandemic on individuals living with spinal cord injury: A qualitative study.

PURPOSE/OBJECTIVE: To explore the impact of the COVID-19 pandemic as experienced and reported by individuals living with a spinal cord injury (SCI). RESEARCH METHOD/DESIGN: Descriptive qualitative design using in-depth semistructured interviews with individuals with SCI (n = 33) followed by thematic analysis. RESULTS: Three main themes described impacts of the COVID-19 pandemic. (a) Impact on health care use; subthemes elaborated that this was attributable to in-person health care facility restrictions or individual decisions to delay care. Individuals with SCI experienced lapses in primary and SCI-specialty care, rehabilitation/therapy services, and home care, but some made use of telehealth services. (b) Impact on weight and/or weight management lifestyle behaviors; subthemes discussed that engagement in physical activity declined because of fitness center closures, recreational activity cancellations, and safety precautions limiting community-based and outdoor activities. The pandemic disrupted participants' independence in purchasing and making preferred food selections which impacted healthy eating. Participants ate due to boredom, at nonmealtimes, and consumed unhealthy foods during the pandemic. (c) Impact on psychosocial factors; included subthemes noting reduced social interactions, social participation, and ability to pursue pastimes with family, friends, and groups they belonged to. The pandemic also triggered emotional reactions such as worry, fear, doubt, demotivation, and feelings of social isolation. CONCLUSIONS: Our findings highlight the magnitude of consequences faced by individuals with SCI when restrictions to health care, healthy lifestyle endeavors, and social participation occurred during the COVID-19 pandemic. Findings may inform SCI health care providers on what is needed in response to future public health or natural disaster crises. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Despite Increasing Costs, Perfusion Machines Expand the Donor Pool of Livers and Could Save Lives.

INTRODUCTION: Liver transplantation is a highly successful treatment for liver failure and disease. However, demand continues to outstrip our ability to provide transplantation as a treatment. Many livers initially considered for transplantation are not used because of concerns about their viability or logistical issues. Recent clinical trials have shown discarded livers may be viable if they undergo machine perfusion, which allows a more objective assessment of liver quality. METHODS: Using the Scientific Registry of Transplant Recipients dataset, we examined discarded and unretrieved organs to determine their eligibility for perfusion. We then used a Markov decision-analytic model to perform a cost-effectiveness analysis of two competing transplant strategies: Static Cold Storage (SCS) alone versus Static Cold Storage and Normothermic Machine Perfusion (NMP) of discarded organs. RESULTS: The average predicted successful transplants after perfusion was 385, representing a 5.8% increase in the annual yield of liver transplants. Our cost-effectiveness analysis found that the SCS strategy generated 4.64 quality-adjusted life years (QALYs) and cost $479,226. The combined SCS + NMP strategy generated 4.72 QALYs and cost $481,885. The combined SCS + NMP strategy had an incremental cost-effectiveness ratio of $33,575 per additional QALY over the 10-year study horizon. CONCLUSIONS: Machine perfusion of livers currently not considered viable for transplant could increase the number of transplantable grafts by approximately 5% per year and is cost-effective compared to Static Cold Storage alone.

Physical and emotional consequences of excess weight as experienced by individuals with spinal cord injuries.

CONTEXT/OBJECTIVE: Excess weight has the potential to carry a substantial physical and emotional burden. A better understanding of perceived consequences of excess weight may facilitate the development of patient-centered programs and interventions to promote weight management efforts in persons with spinal cord injury (SCI). The study objective was to describe consequences of excess weight from the personal perspectives of individuals with SCI. DESIGN: Descriptive qualitative design using in-depth semi-structured interviews and thematic analysis. SETTING: Veterans Health Administration (VHA) SCI System of Care. PARTICIPANTS: Individuals with SCI (n-33). OUTCOME MEASURES: Key themes from thematic analysis. RESULTS: Participants were male (61%), ranged from 29 to 84 years of age, and about half had tetraplegia (55%). Five themes were identified that demonstrate negative consequences of excess weight experienced by individuals with SCI, including: (1) physical health conditions (including chronic conditions and SCI secondary conditions), (2) physical symptoms (such as pain, discomfort, and fatigue), (3) movement challenges, (4) appearance-related concerns, and (5) emotional impacts. CONCLUSIONS: Carrying excess weight is concerning to individuals with SCI and in terms of consequences such onset or exacerbation of chronic conditions, SCI secondary conditions, physical symptoms, e.g. pain, movement impairment (including hampered mobility, difficult transfers and self-care), image/appearance concerns (e.g. body image, clothing misfit), and negative emotions (e.g. unhappy, sad, depressed). Our findings may inform SCI healthcare providers about the consequences of excess weight as experienced by individuals with SCI, highlighting what matters most to persons with SCI and guiding a patient-centered approach to weight management in this population.

Preventive Health Screening in Veterans Undergoing Bariatric Surgery.

INTRODUCTION: Individuals with obesity are vulnerable to low rates of preventive health screening. Veterans with obesity seeking bariatric surgery are also hypothesized to have gaps in preventive health screening. Evaluation in a multidisciplinary bariatric surgery clinic is a point of interaction with the healthcare system that could facilitate improvements in screening. METHODS: This is a retrospective cohort study of 381 consecutive patients undergoing bariatric surgery at a Veterans Affairs Hospital from January 2010 to October 2021. Age- and sex-appropriate health screening rates were determined at initial referral to a multidisciplinary bariatric surgery clinic and at the time of surgery. Rates of guideline concordance at both time points were compared using McNemar's test. Univariate and multivariate analyses were performed to identify the risk factors for nonconcordance. RESULTS: Concordance with all recommended screening was low at initial referral and significantly improved by time of surgery (39.1%‒63.8%; p<0.001). Screening rates significantly improved for HIV (p<0.001), cervical cancer (p=0.03), and colon cancer (p<0.001). Increases in BMI (p=0.005) and the number of indicated screening tests (p=0.029) were associated with reduced odds of concordance at initial referral. Smoking history (p=0.012) and increasing distance to the nearest Veterans Affairs Medical Center (p=0.039) were associated with reduced odds of change from nonconcordance at initial referral to concordance at the time of surgery. CONCLUSIONS: Rates of preventive health screening in Veterans with obesity are low. A multidisciplinary bariatric surgery clinic is an opportunity to improve preventive health screening in Veterans referred for bariatric surgery.

Assessment of Second Primary Cancer Risk Among Men Receiving Primary Radiotherapy vs Surgery for the Treatment of Prostate Cancer.

Importance: Shared decision-making is an important part of the treatment selection process among patients with prostate cancer. Updated information is needed regarding the long-term incidence and risk of second primary cancer after radiotherapy vs nonradiotherapy treatments, which may help to inform discussions of risks and benefits for men diagnosed with prostate cancer. Objective: To assess the current incidence and risk of developing a second primary cancer after receipt of radiotherapy vs nonradiotherapy treatments for prostate cancer. Design, Setting, and Participants: This retrospective cohort study used the Veterans Affairs Corporate Data Warehouse to identify 154 514 male veterans 18 years and older who had localized prostate cancer (tumor stages T1-T3) diagnosed between January 1, 2000, and December 31, 2015, and no cancer history. A total of 10 628 patients were excluded because of (1) incomplete treatment information for the year after diagnosis, (2) receipt of both radiotherapy and a surgical procedure in the year after diagnosis, (3) receipt of radiotherapy more than 1 year after diagnosis, (4) occurrence of second primary cancer or death within 1 year or less after diagnosis, (5) prostate-specific antigen value greater than 99 ng/mL within 6 months before diagnosis, or (6) no recorded Veterans Health Administration service after diagnosis. The remaining 143 886 patients included in the study had a median (IQR) follow-up of 9 (6-13) years. Data were analyzed from May 1, 2021, to May 22, 2022. Main Outcomes and Measures: Diagnosis of a second primary cancer more than 1 year after prostate cancer diagnosis. Results: Among 143 886 male veterans (median [IQR] age, 65 [60-71] years) with localized prostate cancer, 750 (0.5%) were American Indian or Alaska Native, 389 (0.3%) were Asian, 37 796 (26.3%) were Black or African American, 933 (0.6%) were Native Hawaiian or other Pacific Islander, 91 091 (63.3%) were White, and 12 927 (9.0%) were of unknown race; 7299 patients (5.1%) were Hispanic or Latino, 128 796 (89.5%) were not Hispanic or Latino, and 7791 (5.4%) were of unknown ethnicity. A total of 52 886 patients (36.8%) received primary radiotherapy, and 91 000 (63.2%) did not. A second primary cancer more than 1 year after prostate cancer diagnosis was present in 4257 patients (3.0%), comprising 1955 patients (3.7%) in the radiotherapy cohort and 2302 patients (2.5%) in the nonradiotherapy cohort. In the multivariable analyses, patients in the radiotherapy cohort had a higher risk of second primary cancer compared with those in the nonradiotherapy cohort at years 1 to 5 after diagnosis (hazard ratio [HR], 1.24; 95% CI, 1.13-1.37; P < .001), with higher adjusted HRs in the subsequent 15 years (years 5-10: 1.50 [95% CI, 1.36-1.65; P < .001]; years 10-15: 1.59 [95% CI, 1.37-1.84; P < .001]; years 15-20: 1.47 [95% CI, 1.08-2.01; P = .02). Conclusions and Relevance: In this cohort study, patients with prostate cancer who received radiotherapy were more likely to develop a second primary cancer than patients who did not receive radiotherapy, with increased risk over time. Although the incidence and risk of developing a second primary cancer were low, it is important to discuss the risk with patients during shared decision-making about prostate cancer treatment options.

Kidney Stone Events Following Parathyroidectomy vs Nonoperative Management for Primary Hyperparathyroidism.

CONTEXT: Primary hyperparathyroidism (PHPT) is associated with an increased risk of kidney stones. Few studies account for PHPT severity or stone risk when comparing stone events after parathyroidectomy vs nonoperative management. OBJECTIVE: Compare the incidence of kidney stone events in PHPT patients treated with parathyroidectomy vs nonoperative management. DESIGN: Longitudinal cohort study with propensity score inverse probability weighting and multivariable Cox proportional hazards regression. SETTING: Veterans Health Administration integrated health care system. PATIENTS: A total of 44 978 patients with > 2 years follow-up after PHPT diagnosis (2000-2018); 5244 patients (11.7%) were treated with parathyroidectomy. MAIN OUTCOMES MEASURE: Clinically significant kidney stone event. RESULTS: The cohort had a mean age of 66.0 years, was 87.8% male, and 66.4% White. Patients treated with parathyroidectomy had higher mean serum calcium (11.2 vs 10.8mg/dL) and were more likely to have a history of kidney stone events. Among patients with baseline history of kidney stones, the unadjusted incidence of ≥ 1 kidney stone event was 30.5% in patients managed with parathyroidectomy (mean follow-up, 5.6 years) compared with 18.0% in those managed nonoperatively (mean follow-up, 5.0 years). Patients treated with parathyroidectomy had a higher adjusted hazard of recurrent kidney stone events (hazard ratio [HR], 1.98; 95% CI, 1.56-2.51); however, this association declined over time (parathyroidectomy × time: HR, 0.80; 95% CI, 0.73-0.87). CONCLUSION: In this predominantly male cohort with PHPT, patients treated with parathyroidectomy continued to be at higher risk of kidney stone events in the immediate years after treatment than patients managed nonoperatively, although the adjusted risk of stone events declined with time, suggesting a benefit to surgical treatment.

Rates, Variability, and Predictors of Screening for Obesity: Are Individuals with Spinal Cord Injury Being Overlooked?

INTRODUCTION: Individuals with spinal cord injury (SCI) are vulnerable to obesity. Annual obesity screening using body mass index (BMI) is the standard of care mandated by US Veterans Health Administration (VHA) guidelines. Our objective was to determine the rates, variability, and predictors of guideline-concordant annual screening for obesity, given potential challenges of height and weight measurements in individuals with SCI. METHODS: This is a cross-sectional retrospective study using US national VA databases. We identified all VHA patients with chronic SCI in the fiscal year (FY) 2019, their treating facility and frequency of recorded height and weight. We applied mixed-effects logistic regression models to assess associations between annual BMI screening and patient- and facility-level characteristics. RESULTS: Of 20,978 individuals with chronic SCI in VHA in FY19, guideline-concordant annual BMI screening was lacking in 37.9%. Accounting for facility-level factors (geographic region, SCI facility type, volume of patients with SCI treated at the facility), a mixed-effects logistic regression model demonstrated that lack of annual obesity screening was significantly associated with older patient age (p < 0.001) and fewer outpatient encounters (p < 0.001) but not other patient-level factors such as sex, race, level of injury, or rurality. The rate of obesity screening among different facilities within VHA varied widely from 11.1% to 75.7%. CONCLUSION: A large proportion of persons with SCI receiving care in VHA do not receive guideline-concordant annual obesity screening, an especially acute problem in some facilities. Older patients with fewer outpatient encounters are more likely to be missed. To inform the design of interventions to improve identification and documentation of obesity, further study is needed to assess potential barriers to obesity screening in the population with SCI.

Association of Parathyroidectomy With 5-Year Clinically Significant Kidney Stone Events in Patients With Primary Hyperparathyroidism.

OBJECTIVE: Patients with primary hyperparathyroidism (PHPT) are at increased risk of kidney stones. Guidelines recommend parathyroidectomy in patients with PHPT with a history of stone disease. This study aimed to compare the 5-year incidence of clinically significant kidney stone events in patients with PHPT treated with parathyroidectomy versus nonoperative management. METHODS: We performed a longitudinal cohort study of patients with PHPT in a national commercial insurance claims database (2006-2019). Propensity score inverse probability weighting-adjusted multivariable regression models were calculated. RESULTS: We identified 7623 patients aged ≥35 years old with continuous enrollment >1 year before and >5 years after PHPT diagnosis. A total of 2933 patients (38.5%) were treated with parathyroidectomy. The cohort had a mean age of 66.5 years, 5953 (78.1%) were female, and 5520 (72.4%) were White. Over 5 years, the unadjusted incidence of ≥1 kidney stone event was higher in patients who were managed with parathyroidectomy compared with those who were managed nonoperatively overall (5.4% vs 4.1%, respectively) and among those with a history of kidney stones at PHPT diagnosis (17.9% vs 16.4%, respectively). On multivariable analysis, parathyroidectomy was associated with no statistically significant difference in the odds of a 5-year kidney stone event among patients with a history of kidney stones (odds ratio, 1.03; 95% CI, 0.71-1.50) or those without a history of kidney stones (odds ratio, 1.16; 95% CI, 0.84-1.60). CONCLUSION: Based on this claim analysis, there was no difference in the odds of 5-year kidney stone events in patients with PHPT who were treated with parathyroidectomy versus nonoperative management. Time horizon for benefit should be considered when making treatment decisions for PHPT based on the risk of kidney stone events.

Rectal Prolapse: Age-Related Differences in Clinical Presentation and What Bothers Women Most.

BACKGROUND: Rectal prolapse has a diverse symptom profile that affects patients of all ages. OBJECTIVE: We sought to identify bothersome symptoms and clinical presentation that motivated patients who have rectal prolapse to seek care, characterize differences in symptom severity with age, and determine factors associated with bothersome symptoms. DESIGN: This study is a retrospective analysis of a prospectively maintained registry. SETTINGS: This study was conducted at a tertiary referral academic center. PATIENTS: Included were 129 consecutive women with full-thickness rectal prolapse. MAIN OUTCOME MEASURES: The main outcomes measured were primary bothersome symptoms, 5-item Cleveland Clinic/Wexner Fecal Incontinence questionnaire, and the 5-item Obstructed Defecation Syndrome questionnaire. Patients were categorized by age <65 vs age ≥65 years. RESULTS: Cleveland Clinic/Wexner Fecal Incontinence score >9 was more common in older patients (87% vs 60%, p = 0.002). Obstructed Defecation Syndrome score >8 was more common in younger patients (57% vs 28%, p < 0.001). Older patients were more likely than younger patients to report bothersome symptoms of pain (38% vs 19%, p = 0.021) and bleeding (12% vs 2%, p = 0.046). Mucus discharge was reported by most patients (older, 72% vs younger, 66%, p = 0.54) but was bothersome for only 18%, regardless of age. Older patients had more severe prolapse expression than younger patients (at rest, 33% vs 11%; during activity, 26% vs 19%; only with defecation, 40% vs 64%, p = 0.006). Older patients were more likely to seek care within 6 months of prolapse onset (29% vs 11%, p = 0.056). On multivariable regression, increasing age, narcotic use, and nonprotracting prolapse at rest were associated with reporting pain as a primary concern. LIMITATIONS: This was a single-center study with a small sample size. CONCLUSIONS: Rectal prolapse-related bothersome symptoms and health care utilization differ by age. Although rectal pain is often not commonly associated with prolapse, it bothers many women and motivates older women to undergo evaluation. Patient-reported functional questionnaires may not reflect patients' primary concerns regarding specific symptoms and could benefit from supplementation with questionnaires to elicit individualized symptom priorities.

PROLAPSO DE RECTO: INFLUENCIA DE LA EDAD EN DIFERENCIAS VINCULADAS CON LA PRESENTACIÓN CLÍNICA Y LOS SÍNTOMAS MAS DESAGRADABLES: El prolapso de recto tiene una gran variedad de síntomas que afectan a pacientes con edades diferentes.Identificar los síntomas mas molestos y la presentación clínica que motivaron a los pacientes con un prolapso de recto a consultar por atención médica, caracterizar las diferencias de gravedad de los síntomas con relación a la edad y determinar los factores asociados con los síntomas mas molestos.Análisis retrospectivo de un registro prospectivo.Centro académico de referencia terciaria.Consecutivamente 129 mujeres que presentaban un prolapso rectal completo.Síntomas y molestias primarias, cuestionario de incontinencia fecal de la Cleveland Clinic / Wexner de 5 ítems, cuestionario de síndrome de defecación obstruida de 5 ítems. Los pacientes fueron categorizados en < 65 años versus ≥ 65 años.El puntaje de incontinencia fecal de la Cleveland Clinic / Wexner > 9 fue más común en pacientes mayores (87% vs 60%, p = 0.002). La puntuación del síndrome de defecación obstructiva > 8 fue más común en pacientes más jóvenes (57% vs 28%, p <0,001). Los pacientes mayores fueron más propensos que los pacientes jóvenes a informar síntomas y molestias de dolor (38% vs 19%, p = 0.021) y sangrado (12% vs 2%, p = 0.046). La mayoría de los pacientes informaron secresión de moco (mayores, 72% frente a más jóvenes, 66%, p = 0,54), pero sólo el 18% tuvo molestias, independientemente de la edad. Los pacientes mayores tenían una exteriorización de prolapso más grave que los pacientes jóvenes (en reposo, 33% frente a 11%; durante la actividad, 26% frente a 19%; solo con defecación, 40% frente a 64%, p = 0,006). Los pacientes mayores tenían más probabilidades de buscar atención médica dentro de los 6 meses posteriores al inicio del prolapso (29% frente a 11%, p = 0.056). Tras la regresión multivariable, el aumento de la edad, el uso de narcóticos y el prolapso no prolongado en reposo se asociaron con la notificación de dolor como queja principal.Centro único; tamaño de muestra pequeño.Los síntomas y molestias relacionadas con el prolapso rectal y la solicitud de atención médica difieren según la edad. Aunque el dolor rectal a menudo no se asocia comúnmente con el prolapso, incomoda a muchas pacientes y motiva a las mujeres mayores a someterse a un examen médico. Los cuestionarios funcionales con las respuestas de las pacientes pueden no reflejar las preocupaciones principales de éstos con respecto a los síntomas específicos y podrían requerir cuestionarios complementarios para así obtener prioridades individualizadas con relación a los síntomas identificados.

Situating Artificial Intelligence in Surgery: A Focus on Disease Severity.

OBJECTIVES: Artificial intelligence (AI) has numerous applications in surgical quality assurance. We assessed AI accuracy in evaluating the critical view of safety (CVS) and intraoperative events during laparoscopic cholecystectomy. We hypothesized that AI accuracy and intraoperative events are associated with disease severity. METHODS: One thousand fifty-one laparoscopic cholecystectomy videos were annotated by AI for disease severity (Parkland Scale), CVS achievement (Strasberg Criteria), and intraoperative events. Surgeons performed focused video review on procedures with ≥1 intraoperative events (n = 335). AI versus surgeon annotation of CVS components and intraoperative events were compared. For all cases (n = 1051), intraoperative-event association with CVS achievement and severity was examined using ordinal logistic regression. RESULTS: Using AI annotation, surgeons reviewed 50 videos/hr. CVS was achieved in ≤10% of cases. Hepatocystic triangle and cystic plate visualization was achieved more often in low-severity cases (P < 0.03). AI-surgeon agreement for all CVS components exceeded 75%, with higher agreement in high-severity cases (P < 0.03). Surgeons agreed with 99% of AI-annotated intraoperative events. AI-annotated intraoperative events were associated with both disease severity and number of CVS components not achieved. Intraoperative events occurred more frequently in high-severity versus low-severity cases (0.98 vs 0.40 events/case, P < 0.001). CONCLUSIONS: AI annotation allows for efficient video review and is a promising quality assurance tool. Disease severity may limit its use and surgeon oversight is still required, especially in complex cases. Continued refinement may improve AI applicability and allow for automated assessment.

Characteristics of mental health trials registered in ClinicalTrials.gov.

The ClinicalTrials.gov registry was established in 2000 to address concerns about publication bias and public access to information about clinical trials. We aimed to evaluate differences between for-profit and non-profit sponsors of efficacy mental health trials registered in ClinicalTrials.gov on key trial characteristics that relate to data integrity. We also sought to evaluate whether the registry is fulfilling its purpose as a means of promoting transparency between researchers and the public by providing complete and quality information about the trials it contains. We found that trials tend to be small, use a placebo instead of an active comparator, and employ randomization and blinding. We discuss the implications of these design characteristics and the limitations of the registry.

Are parental self-efficacy and family flexibility mediators of treatment for anorexia nervosa?

OBJECTIVE: Family-based treatment (FBT) for adolescent anorexia nervosa (AN) promotes faster weight restoration when compared to other treatments. However, the mechanisms through which this occurs are not clarified. This study explored the trajectories of parental self-efficacy and perceived family flexibility during FBT and systemic family therapy (SyFT). We also explored whether parental self-efficacy mediates the effects of treatment on weight gain early in treatment. METHOD: 158 adolescents (12-18 years old; 89% girls) and their parents were randomized to FBT or SyFT. Parental self-efficacy as well as adolescents' and parental perceptions of the family's flexibility were collected at baseline and at sessions 2, 4, 6, and 8. RESULTS: Over time, only parents in FBT reported significantly greater self-efficacy. The change in maternal self-efficacy over the first 8 weeks of treatment was a significant mediator of session 10 weight gain. There were no significant group differences in perceived flexibility by session 8. DISCUSSION: Both parents in FBT and mothers in SyFT understand early the need to change their family's rules and roles. However, the specific strategies of FBT appear to mediate early weight gain in AN.

A qualitative analysis of male eating disorder symptoms.

Insights into how males experience eating disorder symptoms early in the course of illness are important to improve detection efforts and may also provide valuable information for treatment. In this qualitative study, 10 adolescent males and 10 matched female patients completed standardized questionnaires and were interviewed. Results indicated that although there were many similarities between the genders, females were more likely to describe the involvement of family systems and males were more likely to describe involvement in sports as being catalysts for their disorders. Males in this study were more positive about being in treatment.

The interactions of mothers with eating disorders with their toddlers: identifying broader risk factors.

The connection between maternal eating disorders and feeding and eating problems among their children has been substantially demonstrated. This pilot study focused on the interactions between mothers with eating disorders and their toddlers in non-feeding situations. Twenty-eight dyads of mothers with prenatal eating disorders and their toddlers were compared to a case-matched control group with no eating disorder. Maternal current eating and co-occurring psychopathology, children's symptoms and mother-child interactions were measured. Mothers with eating disorders were less sensitive to their children, tried to control their children's behaviors more, and were less happy during mother-child interactions. The children in the maternal eating disorder group were rated as less responsive to their mothers and their mothers also reported more behavioral problems than those in the control group. Findings imply that maternal eating disorders may be linked with a wide range of adverse maternal and child behaviors beyond those associated with eating.
