Patient Anxiety Related to Patient-Perceived Delays in Surgical Treatment of Skin Cancer.

BACKGROUND: Patients undergoing dermatologic surgery report higher anxiety levels than those undergoing nonsurgical treatments. However, little is known about the association between patient-perceived delays in skin cancer surgery and patient-reported anxiety. OBJECTIVE: To examine the relationship between patient-perceived delays in surgery and patient-reported anxiety. METHODS MATERIALS: Patients undergoing wide local excision or Mohs micrographic surgery were recruited to complete a survey to assess perception of surgical delay and anxiety related to skin cancer surgery using the validated Psychosocial Screen for Cancer-Revised. Demographic and surgical characteristics were collected through chart review. Chi-square and Student t -tests were used to compare demographic and surgical information between patients who did and did not perceive a surgical delay. Differences in anxiety and depression scores for patients who did and did not report a delay were assessed using univariate and multivariate regressions. RESULTS: Twenty-seven percent ( N = 33) of patients perceived a surgical delay. Perception of surgical delay was associated with increased time between biopsy and surgery ( p = .0001) and increased self-reported anxiety scores after controlling for various demographic and surgical factors ( p = .038). CONCLUSION: Patient-perceived delays in dermatologic surgery are associated with increased time to surgery and patient-reported anxiety.

Sex differences in response to a high fat, high sucrose diet in both the gut microbiome and hypothalamic astrocytes and microglia.

Objectives: Obesity is a major epidemic in our population and has emerged as a primary health concern. Consumption of a high fat, high sugar (HFHS) diet can specifically lead to gut dysbiosis, increased inflammation, and neuroinflammation. Interestingly, sex differences in the response to a HFHS diet are emerging. In this study, we investigated the effects of a HFHS diet compared to a low fat, low sugar (LFLS) diet in 8 week old male and female C57Bl/6 mice.Methods: The diet was administered for 14 weeks; body weights and food consumption were evaluated weekly.Results: Male and female mice fed the HFHS diet gained significantly more weight than LFLS-fed mice. However, in agreement with previous studies, males gained significantly more weight on the HFHS diet compared to females fed the same diet. Importantly, we determined significant sex and diet-induced differences to gut microbiome composition using next generation Illumina sequencing. We also observed significantly less astrocyte densitometry and no significant change to microglial morphology in the hypothalamus of Female HFHS compared to Female LFLS. On the other hand, Male HFHS revealed no change to hypothalamic astrogliosis, but increased microgliosis compared to Male LFLS.Discussion: In this study, we determined sex and diet-induced differences in both the gut and the brain, however, future studies will need to be performed in order to test the direct role of the gut microbiome to weight gain and neuroinflammation in male and female mice.

Angiostatic Peptide, Endostatin, Predicts Severity in Pediatric Congenital Heart Disease-Associated Pulmonary Hypertension.

Background Endostatin, an angiogenic inhibitor, is associated with worse pulmonary arterial hypertension (PAH) outcomes in adults and poor lung growth in children. This study sought to assess whether endostatin is associated with disease severity and outcomes in pediatric PAH. Methods and Results Serum endostatin was measured in cross-sectional (N=160) and longitudinal cohorts (N=64) of pediatric subjects with PAH, healthy pediatric controls and pediatric controls with congenital heart disease (CHD) (N=54, N=15), and adults with CHD associated PAH (APAH-CHD, N=185). Outcomes, assessed by regression and Kaplan-Meier analysis, included hemodynamics, change in endostatin over time, and transplant-free survival. Endostatin secretion was evaluated in pulmonary artery endothelial and smooth muscle cells. Endostatin was higher in those with PAH compared with healthy controls and controls with CHD and was highest in those with APAH-CHD. In APAH-CHD, endostatin was associated with a shorter 6-minute walk distance and increased mean right atrial pressure. Over time, endostatin was associated with higher pulmonary artery pressure and pulmonary vascular resistance index, right ventricular dilation, and dysfunction. Endostatin decreased with improved hemodynamics over time. Endostatin was associated with worse transplant-free survival. Addition of endostatin to an NT-proBNP (N-terminal pro-B-type natriuretic peptide) based survival analysis improved risk stratification, reclassifying subjects with adverse outcomes. Endostatin was secreted primarily by pulmonary artery endothelial cells. Conclusions Endostatin is associated with disease severity, disease improvement, and worse survival in APAH-CHD. Endostatin with NT-proBNP improves risk stratification, better predicting adverse outcomes. The association of elevated endostatin with shunt lesions suggests that endostatin could be driven by both pulmonary artery flow and pressure. Endostatin could be studied as a noninvasive prognostic marker, particularly in APAH-CHD.

Factors leading to loss to follow-up after strabismus surgery in children.

PURPOSE: To assess risk factors for loss to follow-up (LTFU) and identify obstacles to follow-up care in these patients. METHODS: The medical records of all children (<18 years old) who underwent strabismus surgery over a 6-year period at a single institution were reviewed retrospectively. Patients were considered LTFU if they failed to attend a follow-up appointment between 3 weeks and 6 months postoperatively. Variables collected for all patients included age, sex, race/ethnicity, and insurance type. A telephone survey of parents/guardians of all patients LTFU was conducted to determine potential barriers to follow-up care. Demographic information was compared between those not LTFU and those LTFU as well as those LTFU and those LTFU who completed the survey. Reasons for LTFU were quantified and classified by category. RESULTS: Patients LTFU were significantly more likely to be black than white or Asian and have state or government-based insurance rather than private or employer-based insurance. The most common reasons cited for not following-up included perceived positive outcome (47%), work conflicts (37%), transportation issues (30%), travel time (30%), and having forgotten (27%). CONCLUSIONS: Patients were LTFU because parents or guardians perceived follow-up as unnecessary, were faced with scheduling or transportation impediments, or simply forgot to appear. Possible remedies include increasing education through teach-back, offering telemedicine appointments, and sending multiple appointment reminders.
