How Quaternary climatic and geological disturbances influenced the composition of Neotropical forests is hotly debated. Rain fall and temperature changes during and/or immediately after the Last Glacial Maximum (LGM) are thought to have strongly affected the geographical distribution and local abundance of tree species. The paucity of the fossil records in Neotropical forests prevents a direct reconstruction of such processes. To describe community-level historical trends in forest composition, we turned therefore to inferential methods based on the reconstruction of past demographic changes...

As incentives grow for healthcare organizations to improve the patient experience, an increasing number choose to add consumers directly into their leadership structures. In this final installment about the value of patient and family advisory councils, the senior director of quality at a large, Magnet®-recognized Texas hospital explains how tapping into a well-established Magnet culture helped the organization adopt innovative approaches that produced positive change. Based on an interview with the author, she notes that seeing basic issues through patients' eyes challenged long-held beliefs and led to improvements in a wide variety of areas...

We report on the use of home- and community-based services and other senior services and factors affecting utilization of both among Americans over age 60 in the Health and Retirement Study. Those using home- and community-based services were more likely than to be older, single, Black, lower income, receiving Medicaid, and in worse health. Past use of less traditional senior services, such as exercise classes and help with tax preparation, were found to are associated with current use of home- and community-based services...

Missing data is a common issue in community health and epidemiological studies. Direct removal of samples with missing data can lead to reduced sample size and information bias, which deteriorates the significance of the results. While data imputation methods are available to deal with missing data, they are limited in performance and could introduce noises into the dataset. Instead of data imputation, a novel method based on additive least square support vector machine (LS-SVM) is proposed in this paper for predictive modeling when the input features of the model contain missing data...

HIV disproportionately affects Black men who have sex with men (MSM), yet there are few evidence-based programs that respond to the diverse realities of Black MSM communities. This article examines the development of Real Talk, a new harm reduction-based, sexual health intervention for Black MSM. We first analyze the key themes from our formative research: (1) stigma, discrimination, and intersectionalities in the lives of Black MSM, (2) the importance of safe spaces and community provided by health promotion programs, and (3) moving beyond condoms in sexual health messaging...

OBJECTIVE: Clinic-based studies have shown that patients with human immunodeficiency virus (HIV) gain weight after initiation of antiretroviral therapy (ART). This study aimed to determine whether the scale-up of ART was associated with a population-level increase in body mass index (BMI) and blood pressure (BP) in a community with high HIV and obesity prevalence. METHODS: A household survey was conducted in rural KwaZulu-Natal before ART scale-up (in 2004) and when ART coverage had reached 25% (in 2010)...

The growing threats to biodiversity and global alteration of habitats and species distributions make it increasingly necessary to consider evolutionary patterns in conservation decision-making. Yet there is no clear-cut guidance on how genetic features can be incorporated into conservation planning processes, with multiple molecular markers and several genetic metrics for each marker type to choose from. Genetic patterns also differ between species, but the potential trade-offs amongst genetic objectives for multiple species in conservation planning are currently understudied...

The Principal Response Curve (PRC) method is a constrained ordination method developed specifically for the analysis of community data collected in mesocosm experiments which provides easily understood summaries and graphical representations of community response to stress. PRC is a redundancy analysis (RDA) method and is usually performed on log-transformed abundance data. The choice of a measure of dissimilarity between samples and the choice of the data transformation significantly affect the results of multivariate analysis...

A total of 208 therapists and therapists-in-training were surveyed to better understand if clinical assessments and recommendations regarding "sex addiction" changed based upon a client's gender, relationship status, or exclusivity status. Using clinical vignettes, this study examined the clinical assessment and recommendations of licensed mental health providers (n = 92) and mental health providers in-training (n = 116). Results indicated that professional ratings differed based on relationship exclusivity and gender; specifically, female nonmonogamous behavior was rated more negatively than male nonmonogamous behavior, while male monogamous behavior was rated more negatively than female monogamous behavior...

The Siphonaptera are parasitic insects of endothermic animals and Ctenocephalides felis and Pulex irritans are important parasites of dogs. This study evaluated the effect of hair coat length and time of year on the population size of C. felis and P. irritans in naturally infested dogs. Fleas were collected from 14 dogs on a monthly basis for a year (February 2015 to January 2016) at a rural property in Bagé, Rio Grande do Sul, Brazil. The dogs were divided into two groups based on hair coat length: short coat (coat length < 5...

Previous investigations have shown that changes in total prostate volume (TPV) are highly variable among aging men, and a considerable proportion of aging men have a stable or decreasing prostate size. Although there is an abundance of literature describing prostatic enlargement in association with benign prostatic hyperplasia, less is known about the appropriate age cut-off points for TPV growth rate. In this community-based cohort study, TPV was examined once a year in men who had consecutive health checkup, during a follow-up of 4 years...

Nosocomial outbreaks of bacteria are well documented. Based on these incidents, and the heavy usage of antibiotics in hospitals, it has been assumed that antibiotic resistance evolves in hospital environments. To test this assumption, we studied resistance phenotypes of bacteria collected from patient isolates at a community hospital over a 2.5-year period. A graphical model analysis shows no association between resistance and patient information other than time of arrival. This allows us to focus on time-course data...

The increasing demand which requires ascertaining the legal age of undocumented individuals who reach the various countries of the European Community means that new lines of research must be developed which help respond to questions posed by the Justice Administration. For this reason, this study has been designed on the basis of fusion times of the proximal humeral epiphysis. Moreover, the ultrasound scan has been used as the diagnostic method. It is a non-invasive technique, unlike the radiograph, which is used under current standards for the forensic diagnosis of age...
