BACKGROUND This study validates cut-points for a frailty index (FI) to identify seniors at risk of a hospital-related event and estimates the number of frail seniors living in the community. The FI developed by Rockwood and Mitnitski defines levels of frailty based on scores of 0 to 1.0. DATA AND METHODS The cut-point validation was conducted using Stratum-Specific Likelihood Ratios applied t...

Record linkage and capture-recapture models were used to estimate the number of cases of human leptospirosis in the health district of Santa Maria, RS in southern Brazil. Twelve months of laboratory, hospital and epidemiological surveillance data were matched by name, age, residence and the month of diagnosis. Only laboratory-confirmed cases were considered. The record linkage revealed more tha...

Human cystic echinococcosis (CE) is known to be endemic in the Tibet Autonomous Region (TAR), China; however, there is relatively little data from hospital records or community prevalence studies, and the situation regarding occurrence of human alveolar echinococcosis (AE) is unclear. Here we review the available reports about human echinococcosis in the seven prefectures of TAR. In addition, t...

The goal in much of medical research is to answer the question: “What will a patient’s outcome, Y, be if the patient is given a specific treatment, T?” We focus our efforts on understanding how to intervene in order to improve outcomes for our patients. Some of the strategies for estimating the effect of a treatment are well known. The foremost technique is the foundational technique of Science...
