Objective: To assess and quantify the surgical learning curve of holmium laser enucleation of the prostate (HoLEP) of a single surgeon.
Methods: A retrospective analysis of 253 consecutive cases performed by the same surgeon from 2006 to 2013 was conducted. Primary outcomes included enucleation ratio and morcellation efficiencies and complication rates. Three-month postoperative prostate-specific antigen values were used as secondary measures. Cases were divided into cohorts of 20 cases to assess changes in means analyzed through Analysis of Variance (ANOVA) tests. Scatter plots of cases with a best-fit line were drawn to analyze the learning curve.
Results: The mean age of patients across the cases was 69.21 years with an average transrectal ultrasound prostate volume of 95.84 cc. Enucleation ratio efficiency was significantly different between cohorts (P = .02) plateau after 50-60 cases conducted. Similarly, a significant difference is shown for morcellation efficiency (P = .01) with stabilization in performance after 60 cases. Complication rates decreased through the caseload but did not show a statistical difference (P = .62) or plateauing on the graph. Finally, no difference between 3-month postoperative prostate-specific antigen values was seen (P = .083); however, a learning curve of 50 cases was observed graphically.
Conclusion: Within our single-surgeon cohort, we experienced a learning curve of 40-60 cases for the HoLEP procedure. Large variability in performance late into the caseload demonstrates the technical difficulty of HoLEP. Owing to this, adjuncts to training such as simulation-based training may be of use for the new surgeon to shorten the initial phase of learning.

Background: Environmental change in coastal areas can drive marine bacteria and resulting infections, such as those caused by , with both foodborne and nonfoodborne exposure routes and high mortality. Although ecological drivers of in the environment have been well-characterized, fewer models have been able to apply this to human infection risk due to limited surveillance.
Objectives: The Cholera and Other Illness Surveillance (COVIS) system database has reported infections in the United States since 1988, offering a unique opportunity to both explore the forecasting capabilities machine learning could provide and to characterize complex environmental drivers of infections.

Background: Type 2 diabetes (T2D) is a leading cause of premature morbidity and mortality globally and affects more than 100 million people in the world's most populous country, India. Nutrition is a critical and evidence-based component of effective blood glucose control and most dietary advice emphasizes carbohydrate and calorie reduction. Emerging global evidence demonstrates marked interindividual differences in postprandial glucose response (PPGR) although no such data exists in India and previous studies have primarily evaluated PPGR variation in individuals without diabetes.

Purpose: The purpose of this study was to develop and validate a deep-learning model for noninvasive anemia detection, hemoglobin (Hb) level estimation, and identification of anemia-related retinal features using fundus images.
Methods: The dataset included 2265 participants aged 40 years and above from a population-based study in South India. The dataset included ocular and systemic clinical parameters, dilated retinal fundus images, and hematological data such as complete blood counts and Hb concentration levels.

Background: The introduction of total mesorectal excision improved locoregional control for rectal adenocarcinoma significantly. Standardisation of the technique of LPLND is lacking in literature.
Methods: We describe the current practices of case selection and technical details of lateral lymph node dissection in rectal cancer.

Purpose: The aim of the study was to evaluate operative time and postoperative complications of 4 post-training specialized surgeons.
Methods: This was a pilot retrospective chart review to determine the learning curve of a Shouldice primary inguinal hernia repair (Shouldice Repair) of 4 post-training specialized surgeons, at the Shouldice Hospital. The first 300 Shouldice Repairs (early learning block) were compared to their 900-1,000 repairs as the primary operating surgeon (late learning block).
