Background: The immune system and vascular endothelial growth factor (VEGF) may be influential in melanoma behavior. We performed a prospective, exploratory analysis in 10 stage III and 22 stage IV melanoma patients to observe factors influencing outcomes. Patients and methods: Patients accrued during 2010 and 2011 were treated according to standard protocols for disease stage. We analyzed selected biomarkers for predictive patterns of clinical response. Survival outcomes were calculated using Kaplan-Meier curves. Results: Baseline LDH was negatively correlated with length of survival and positively correlated to baseline VEGF in stage IV melanoma patients. We found a positive correlation between peripheral blood Treg concentrations and baseline VEGF in stage IV patients. No stage III patients died during the study period; median survival for stage IV patients was 48 months using a Kaplan-Meier survival curve, which illustrates the enrichment for exceptional stage IV survivors. Six stage IV patients remain disease free, including 4 of the 10 patients who received IL-2 +/− metastatectomy. Conclusions: Recent advances in immunotherapy have demonstrated durable therapeutic responses which may favorably impact survival. Examining T-cell characteristics of metastatic melanoma patients may gain further insight into underlying immunomodulation mechanisms to guide improved therapies.

Introduction: An evaluation of complication rates in different abdominal lipectomy techniques with relationship to body mass index (BMI) and other risk factors.Methods: We identified patients who underwent an abdominal lipectomy at our institution from January 2015 to July 2020. Those with concurrent hernia repair were excluded. Patients were classified into 2 groups: (1) horizontal lipectomy with or without umbilical translocation and (2) inverted-T lipectomy with translocation. Demographics, operative details, and postoperative complications were collected for 1 year postoperatively. Bivariate analyses were conducted to determine factors associated with type of procedure and complications. Crude and stratum-specific (based on BMI) odds ratios for complications were calculated for the inverted T as compared with the horizontal group. A replicate analysis using the national Tracking Operations and Outcomes for Plastic Surgeons (TOPS) as a single cohort was performed.Results: At our institution, 362 patients (group 1 = 196, group 2 = 166) were included. A total of 40.9% of patients experienced at least one complication at 1 year postoperatively with the complication rate decreasing to 28.0% when analyzed at the 30-day postoperative period. Specifically, wound disruption rates were highest in group 2 (39.8%) compared with group 1 (15.6%;P< 0.0001). The odds of experiencing a complication were greater in the inverted-T group overall and within each stratum of BMI. When dividing the cohort based on BMI class (normal weight, overweight, class I, class II, and class III obesity), the incidence of wound disruption increased as did BMI (2.6%, 22.2%, 27.2%, 48.2%, and 56.3%, respectively;P< 0.0001). The TOPS data set included 23,067 patients and showed an overall complication rate of 13.1% at 30-day postop. Overall, wound disruption rate was 4.6%. Compared with normal weight patients, the odds of experiencing a complication trended higher with each stratum of BMI. Other factors associated with complications included BMI, tobacco use, diabetes, American Society of Anesthesiology, prior massive weight loss, and LOS.Conclusions: The increasing complication rate within each BMI stratum of the large sample size of the TOPS patient cohort, in addition to our similar institutional trends, suggests that a staged procedure may be more appropriate for higher BMI patients. Surgical technique modification with limited flap undermining in patients undergoing inverted-T lipectomy to preserve flap perfusion may also decrease overall complication rates.

Coronavirus disease 2019 (COVID-19) is associated with diffuse lung injury that can progress to acute respiratory distress syndrome, multisystem-organ failure, and death. The inflammatory storm seen in many COVID-19 patients closely resembles secondary hemophagocytic lymphohistiocytosis (sHLH) which has been described in other virus-associated severe sepsis. We sought to describe the incidence of sHLH in COVID-19 infected patients. In this retrospective study, we reviewed the records of critically ill COVID-19 positive patients to determine the incidence of sHLH. An H-score for sHLH diagnosis was determined for each study participant, with a score greater than 169 points needed for diagnosis. A quaternary referral center in suburban Pennsylvania, USA. All study participants had a positive COVID-19 test, and were deemed critically ill defined as receiving invasive mechanical ventilation and/or who expired. Of the 246 records identified, 242 records met inclusion criteria and were reviewed. Eighty five patients were excluded from analysis due to missing H-score data parameters. Overall, 32 of 157 (20.38%, 95% CI:14.38-27.54%) patients met diagnostic criteria for sHLH. The average age was 69.42 years (standard deviation (SD) 14.81). Patients diagnosed with sHLH were more likely to be younger (61.09 years vs 69.38 years, P = 0.0036), male (71.88% vs 52.00%, P = 0.0433), and require mechanical ventilation (96.88% vs 72.80%, P = 0.0035). Among critically ill COVID-19 positive patients, the incidence of sHLH is higher than previously reported in patients with non-COVID-19 related sepsis. Clinicians caring for COVID-19 patients should consider this secondary diagnosis and subsequent appropriate treatments, especially in those requiring mechanical ventilation.

Chronic pain is a common diagnosis that patients may face, resulting in increased morbidity and mortality and affecting the overall quality of life. In addition to established multidisciplinary pain management, medical cannabis may offer an approach to improving pain outcomes and functionality. This case involves a 72-year-old female patient, with chronic neck, lower back, and diffuse arthritic pain due to comorbid osteoarthritis (OA), scleroderma, and scoliosis. Medical cannabis therapy was certified based on the goals of improving pain control and simultaneously reducing the patient’s chronic opioid medication dose. Using potential opioid alternatives, such as medical cannabis, may prove beneficial to clinicians looking to improve pain management and reduce opioid therapy in patients.

Homeless youth are a vulnerable population. A volunteer clinic supported by medical students in northeastern Pennsylvania provides shelter and healthcare to adolescents seeking refuge. We set out to determine the immunization status of youth in the shelter and evaluate for associations of immunization deficiency with demographics or biopsychosocial factors. After IRB approval, a retrospective cohort study was performed from existing clinical records at the shelter 2/2015-9/2019. Chart abstraction included variables such as demographics (including age, sex, and race/ethnicity), biopsychosocial factors (including childhood trauma/abuse history, substance abuse history, and sexual activity), and immunization history. A total of 440 charts were analyzed. When comparing demographics of patients that had complete vaccine regimens versus those who did not, the race was statistically significant (p=.006). The most prominent difference in race was seen for Black/African American patients; only 19.57% had a completed vaccine regimen documented. Regarding immunization history, vaccine schedules of hepatitis B, measles mumps rubella (MMR), inactivated polio vaccine (IPV), and varicella were most likely to be complete; pneumococcal conjugate vaccine (PCV) 13, rotavirus, influenza, and human papillomavirus vaccine (HPV) were least likely. There was no association found between a completed vaccine regimen and biopsychosocial variables. A larger portion of females (37.35%) completed the HPV vaccine compared to males (23.14%) (p=.009). In this single-site study, this vulnerable, at-risk population of sheltered adolescents lacked the vaccinations recommended by the Centers for Disease Control and Prevention. Racial disparities further compounded this vulnerability for Black/African American teens. Additionally, a significantly greater number of female patients received the HPV vaccine compared to males.
