RESUMEN
Currently, there is a paucity of data regarding Single Port (SP) robotic-assisted laparoscopic prostatectomy (RALP). Our objective was to compare our single-institution single-surgeon SP RALP experience to our XI RALP experience with regard to patient selection, perioperative data, and outcomes. Patients who underwent prostatectomy at our institution between August 2019 and April 2021 were selected for analysis. All patients had biopsy confirmed prostate cancer. All surgeries were performed by one urologist at our institution to limit inter-surgeon variability. Demographic and clinical information were extracted from the medical record in standardized fashion. All documented classifications were graded using the Clavien-Dindo classification system. Patients with previous prostate cancer therapies were excluded. Categorical variables were compared using Chi-square or Fisher's exact test where appropriate. Continuous variables were compared using t tests or Wilcoxon rank sum tests where appropriate. Complete records were available for 208 patients. Of the total patient population 127 (61.1%) underwent SP prostatectomy compared to 81 (38.9%) underwent XI prostatectomy. There was no significant difference between the two cohorts in terms of mean age (65 vs. 66 years; p = 0.60), BMI (29.2 vs. 30.1; p = 0.22), preop ASA score ≥ 3 (68.5% vs. 64.2%; p = 0.52), or preop PSA (7.1 vs. 7.4, p = 0.94). There no difference in procedure time for SP prostatectomy (170 vs. 168 min, p = 0.035), estimated blood loss (100 vs. 100 mL; p = 0.14), or average length of stay (1 vs. 1 days; p = 0.22). There was a significant difference in Gleason grade group between the two cohorts with patients undergoing XI RALRP more likely to have higher stage disease (p = 0.025) and a trend towards higher D'Amico risk scores in the XI group (p = 0.053). There was no difference in rate of positive surgical margins (29.9% vs. 29.6%; p = 0.96). There was no difference in the distribution of complications between the two groups (p = 0.99) with 89% of patients having no complication. There was no difference in the number of lymph nodes removed by modality (p = 0.94). To date, this study represents one of the largest cohorts of patients who underwent SP RALP. Importantly, it is among the first studies comparing perioperative variables between the SP and XI platforms. As surgeons become more facile with the SP system there appear to minimal differences in patient factors, perioperative results, or outcomes between the platforms. These findings provide evidence that surgeons who are competent on the XI platform can confidently perform SP RALPs through a single incision without compromising outcomes.

Background: Pancreatitis accounts for more than $2.5 billion of healthcare costs and remains the most common gastrointestinal (GI) admission. Few contemporary studies have assessed temporal trends of incidence, complications, management, and outcomes for acute pancreatitis in hospitalized patients at the national level. Methods: We used data from one of the largest hospital-based databases available in the United States, the Healthcare Cost and Utilization Project's (HCUP) State Inpatient Database, from 10 states between 2008 and 2015. We included patients with a diagnosis of acute pancreatitis (ICD-9 CM 577.0). Patient- and hospital-level data were used to estimate incidence and inpatient mortality rates. Results: From 80,736,256 hospitalizations, 929,914 (1.15%) cases of acute pancreatitis were identified, 186,226 (20.2%) of which were caused by gallbladder disease). The median age was 53 years (interquartile range [IQR], 41-67) and 50.8% were men. In-hospital mortality was 2.5% and crude mortality rates declined from 2.9% to 2.0% over the study period. Admission year remained significant after adjusting for patient demographics and comorbidities (odds ratio [OR], 0.90; 95% confidence interval [CI], 0.89-0.90; p < 0.001). Gallbladder disease was associated with decreased odds of mortality (OR, 0.60; 95% CI, 0.57-0.62). Median length of stay was four days (IQR, 2-7) and decreased over time. The rates of surgical and endoscopic interventions were highest in 2011 (peak incidence of 16.1% and 9.5%, respectively) and have been decreasing since. Surgical providers were, on average, more likely than medical providers to perform surgery in both those with and without gallbladder disease etiology (gallbladder disease OR, 7.11; 95% CI, 5.46-9.25; non-gallbladder disease OR, 20.50; 95% CI, 16.81-25.01), endoscopy (gallbladder disease OR, 1.22; 95% CI, 0.87-1.72; non-gallbladder disease OR, 1.60; 95% CI, 1.18-2.16), or both (gallbladder disease OR, 7.00; 95% CI, 5.22-9.37; non-gallbladder disease OR, 8.85; 95% CI, 5.61-13.96). Conclusions: The incidence of pancreatitis, from 2008 to 2015, has increased whereas inpatient mortality (i.e., case fatality) has decreased. Understanding temporal trends in outcomes and management along with provider, hospital, and regional variation can better identify areas for future research and collaboration in managing these patients.

BACKGROUND: Radiation exposure is a serious concern with usage of serial multigated acquisition (MUGA) scans (7.8mSv/study) for chemotherapy-related cardiotoxicity (CRC) screening. The current practice with respect to the imaging modalities chosen for cardiotoxicity screening and related radiation exposure has not been studied. MATERIALS AND METHODS: We performed a serial cross-sectional study from 2011 to 2014, evaluating the relative usage of the three imaging modalities for CRC screening. RESULTS: MUGA scan usage decreased from 30.4% to 16.7%, echocardiogram (Echo) utilization increased from 68.7% to 80.4% and cardiac magnetic resonance (CMR) usage increased from 0.9% to 2.9% in the 4-year period. Estimated total radiation exposure and secondary cancer risk can increase significantly in certain subgroups when MUGA scan is employed for serial cardiac imaging. CONCLUSION: Increased awareness of radiation risks from MUGA, as well as increasing focus on early detection of cardiotoxicity using Echo and CMR, are possible reasons behind the observed trends.

BACKGROUND: Induced pluripotent stem cells (iPSCs) can be differentiated into potentially unlimited lineages of cell types for use in autologous cell therapy. However, the efficiency of the differentiation procedure and subsequent function of the iPSC-derived cells may be influenced by epigenetic factors that the iPSCs retain from their tissues of origin; thus, iPSC-derived cells may be more effective for treatment of myocardial injury if the iPSCs were engineered from cardiac-lineage cells, rather than dermal fibroblasts. METHODS AND RESULTS: We show that human cardiac iPSCs (hciPSCs) can be generated from cardiac fibroblasts and subsequently differentiated into exceptionally pure (>92%) sheets of cardiomyocytes (CMs). The hciPSCs passed through all the normal stages of differentiation before assuming a CM identity. When using the fibrin gel-enhanced delivery of hciPSC-CM sheets at the site of injury in infarcted mouse hearts, the engraftment rate was 31.91%±5.75% at Day 28 post transplantation. The hciPSC-CM in the sheet also appeared to develop a more mature, structurally aligned phenotype 28 days after transplantation and was associated with significant improvements in cardiac function, vascularity, and reduction in apoptosis. CONCLUSIONS: These data strongly support the potential of hciPSC-CM sheet transplantation for the treatment of heart with acute myocardial infarction.
