Causes of Weight Loss in a Community Nursing Home

Abstract: Objective: To determine the causes of weight loss in nursing home residents. Design: Retrospective chart review of all weights over the previous 6 months and an in-depth examination of all residents who lost 5 or more pounds over that period. Setting: A for-profit community nursing home in an urban area. Subjects: All residents who had been in the nursing home for 3 or more months. Their mean age was 80.1 years, and 89% were female. Results: Weight loss of 5 pounds or more occurred in 19% of subjects. Only 15% of subjects had lost 5% of body weight, and 4% had lost more than 10% of their body weight. Depression accounted for 36% of the weight loss. Other causes of anorexia included medications, psychotropic drug reduction, swallowing disorders, paranoia, dementia with apraxia, gallstones, and obsessive-compulsive disorder. Increased energy utilization as a cause of weight loss was seen in two residents who wandered incessantly, one with tardive dyskinesia and one with chronic obstructive pulmonary disease. Dehydration was the cause of weight loss in two residents, and one resident had intentional weight loss for obesity. Cancer was the cause of weight loss in two residents. Four of 30 residents had more than one cause of weight loss. One of 25 tube-fed residents displayed weight loss. Conclusions: A single cause of weight loss can be identified in most nursing home residents. Depression is the most common cause of weight loss. Psychotropic drug reduction may cause weight loss. The majority of causes of weight loss in a community nursing home are potentially treatable.

Kidney-Failure Risk Projection for the Living Kidney-Donor Candidate

Abstract: BackgroundEvaluation of candidates to serve as living kidney donors relies on screening for individual risk factors for end-stage renal disease (ESRD). To support an empirical approach to donor selection, we developed a tool that simultaneously incorporates multiple health characteristics to estimate a person’s probable long-term risk of ESRD if that person does not donate a kidney. MethodsWe used risk associations from a meta-analysis of seven general population cohorts, calibrated to the population-level incidence of ESRD and mortality in the United States, to project the estimated long-term incidence of ESRD among persons who do not donate a kidney, according to 10 demographic and health characteristics. We then compared 15-year projections with the observed risk among 52,998 living kidney donors in the United States. ResultsA total of 4,933,314 participants from seven cohorts were followed for a median of 4 to 16 years. For a 40-year-old person with health characteristics that were similar to those of...

Metajournalistic Discourse and the Meanings of Journalism: Definitional Control, Boundary Work, and Legitimation

Abstract: Situating journalism as a cultural practice charged with delivering valid accounts of the world necessitates a theory of metajournalistic discourse to explain how meanings around journalism develop. Through metajournalistic discourse, various actors inside and outside of journalism compete to construct, reiterate, and even challenge the boundaries of acceptable journalistic practices and the limits of what can or cannot be done. Based on the premises that journalism is variable, reliant on context, and produced through social relationships, this article develops a theory of metajournalistic discourse that connects three components-actors, sites/audiences, and topics-to processes of definition making, boundary work, and legitimation.

Incidence and Predictors of Myocardial Infarction after Kidney Transplantation

Abstract: The risk and predictors of post-kidney transplantation myocardial infarction (PTMI) are not well described. Registry data collected by the United States Renal Data System were used to investigate retrospectively PTMI among adult first renal allograft recipients who received a transplant in 1995 to 2000 and had Medicare as the primary payer. PTMI events were ascertained from billing and death records, and participants were followed for up to 3 yr after transplant or until the end of observation (December 31, 2000). Extended Cox's hazards analysis was used to identify independent clinical correlates of PTMI (hazard ratio [HR]) and to examine PTMI as an outcomes predictor. Among 35,847 eligible participants, the cumulative incidence of PTMI was 4.3% (95% confidence interval [CI], 4.1 to 4.5%), 5.6% (95% CI, 5.3 to 5.8%), and 11.1% (95% CI, 10.7 to 11.5%) at 6, 12, and 36 mo, respectively. Risk factors for PTMI included older recipient age, pretransplantation comorbidities (diabetes, angina, peripheral vascular disease, and MI), transplantation from older donors and deceased donors, and delayed graft function. Women, blacks, Hispanics, and employed recipients experienced reduced risk. The hazard of PTMI rose after a diagnosis of posttransplantation diabetes (HR, 1.60; 95% CI, 1.35 to 1.88) and markedly increased after graft failure (HR, 2.78; 95% CI, 2.41 to 3.19). In separate analyses, PTMI predicted death-censored graft failure (HR, 1.89; 95% CI, 1.63 to 2.20) and strongly predicted death in a manner that declined with time after PTMI. Risk factors for PTMI include potentially modifiable posttransplantation complications. Because PTMI in turn predicts graft failure and death, reducing the risk for PTMI may improve outcomes after kidney transplantation.
