Hysterectomy Volume Among Recent Obstetrics and Gynecology Residency Graduates.
Female Pelvic Med Reconstr Surg
June 2021
Article Synopsis
- Recent graduates of residency programs have decreased exposure and performance rates of vaginal hysterectomy compared to senior surgeons, largely opting for abdominal methods instead.
- A study of hysterectomy data in Massachusetts from 2005 to 2014 showed that recent graduates performed an average of only 3 to 4 hysterectomies per year, often choosing laparotomy over vaginal methods.
- The difference in vaginal hysterectomy rates between recent graduates and senior surgeons was significant, but was minimized when accounting for patient age and reasons for the surgery.
Social Cost of Blindness Due to AMD and Diabetic Retinopathy in the United States in 2020.
Ophthalmic Surg Lasers Imaging Retina
April 2020
Article Synopsis
- The study aims to assess the financial impact of blindness caused by wet age-related macular degeneration (wAMD), diabetic macular edema (DME), and proliferative diabetic retinopathy (PDR) in the U.S. for the year 2020.
- It estimates that the annual excess costs due to blindness average $4,944 in direct costs and $54,614 in indirect costs per blind individual, along with a quality-adjusted life year loss of 0.214.
- Overall, the total societal cost of blindness from these conditions in 2020 is projected to be $20 billion and is expected to triple by 2050, with a significant portion attributed to indirect costs.
Medicare Patient Referral Networks to Female Pelvic Medicine and Reconstructive Surgeons Across the United States.
Female Pelvic Med Reconstr Surg
February 2021
Objective: The source of urogynecology patient referrals remains poorly understood. We used novel methods to identify referral networks to female pelvic medicine and reconstructive surgeons (FPMRS) and to determine factors associated with physician connections.
Methods: A retrospective analysis of Centers for Medicare and Medicaid Services data with physician sharing relationships spanning 180 days during 2015 was performed.
Purpose: The estimation of the radon hazard of a future construction site should ideally be based on the geogenic radon potential (GRP), since this estimate is free of anthropogenic influences and building characteristics. The goal of this study was to evaluate terrestrial gamma dose rate (TGD), geology, fault lines and topsoil permeability as predictors for the creation of a GRP map based on logistic regression.
Method: Soil gas radon measurements (SRC) are more suited for the estimation of GRP than indoor radon measurements (IRC) since the former do not depend on ventilation and heating habits or building characteristics.
Purpose: According to estimations around 230 people die as a result of radon exposure in Switzerland. This public health concern makes reliable indoor radon prediction and mapping methods necessary in order to improve risk communication to the public. The aim of this study was to develop an automated method to classify lithological units according to their radon characteristics and to develop mapping and predictive tools in order to improve local radon prediction.

Methods: We looked at about 240,000 IRC measurements carried out in about 150,000 houses. As predictor variables we included: building type, foundation type, year of construction, detector type, geographical coordinates, altitude, temperature and lithology into the kernel estimation models.
Purpose: In Switzerland, nationwide large-scale radon surveys have been conducted since the early 1980s to establish the distribution of indoor radon concentrations (IRC). The aim of this work was to study the factors influencing IRC in Switzerland using univariate analyses that take into account biases caused by spatial irregularities of sampling.
Methods: About 212,000 IRC measurements carried out in more than 136,000 dwellings were available for this study.
