Approximately two-thirds of the world's older adults live in developing nations. By 2050, as many as 80% of such older people will live in low- and middle-income countries. In sub-Saharan Africa alone, the number of individuals aged 60 and older is projected to reach 163 million. Despite this demographic wave, the majority of Africa has limited access to qualified geriatric health care.(3) Although foreign aid and capacity-building efforts can help to close this gap over time, it is likely that failure to understand the unique context of Africa's older adults, many of whom are marginalized, will lead to inadequacies in service delivery and poor health outcomes...

Gastric intestinal metaplasia (GIM) is a high risk for intestinal type gastric cancer; however, there is a limitation for detection of GIM using white light imaging (WLI). Image-enhanced endoscopy (IEE) is more advantageous than WLI for optical diagnosis of GIM (1). Linked color imaging (LCI) (FUJIFILM Co., Tokyo, Japan) was newly developed for advanced IEE and enables visualization of red lesions that appear redder and whitish red lesions that appear whiter during routine endoscopy (2). GIM is observed as a lavender color that is distinguishable from the circumferential mucosa without GIM by using LCI (Figure 1)...

BACKGROUND: Assessment of blood compatibility, typically by tube agglutination (TUBE) and hemolysis crossmatch or, less commonly, by blood typing and alloantibody screening, often is performed before blood transfusion in horses. In contrast, gel column (GEL) and immunochromatographic strip (STRIP) techniques are preferred for compatibility testing in dogs and cats. OBJECTIVE: To determine the accuracy of novel and standard crossmatch and typing methods. ANIMALS: Thirty-eight healthy horses, previously blood typed and alloantibody screened...

PURPOSE: Laparoscopic surgery for locally advanced colorectal cancer suspected of direct invasion to adjacent organs or structures remains controversial because of its high conversion rate, inadequate oncologic clearance and surgical outcomes. This study retrospectively evaluated the short-term outcomes of laparoscopic multivisceral resection for colorectal cancer and investigated the factors influencing conversion to open surgery. METHODS: Between 2010 and 2015, 39 patients who underwent laparoscopic multivisceral resection for colorectal cancer intraoperatively suspected of direct invasion to adjacent organs or structures were included...

INTRODUCTION: Infiltration of non-small-cell lung cancer (NSCLC) by CD8(+) T lymphocytes predicts improved patient survival; however, heterogeneity of intratumoral localization complicates this assessment. Strategies for tumor sampling may not accurately represent the whole tumor. We hypothesized that sampling strategies may alter the identification of tumors with high CD8 density and affect the prognostic significance. PATIENTS AND METHODS: Twenty-three primary NSCLC tumors were immunohistochemically stained for CD8 and were assessed using automated software with eight different sampling strategies or the whole tumor...

Patients with end-stage renal disease (ESRD) who present with critical limb ischemia (CLI) have become an increasingly common and complex treatment problem for vascular surgeons. Dialysis patients have high short-term mortality rates regardless of whether revascularization is pursued. ESRD patients with CLI can be managed with: local wound care, endovascular or surgical revascularization, or amputation. Some patients may heal small foot wounds with local wound care alone, even if distal perfusion is marginal, as long as any infectious process has been controlled...

Natural acquisition of small amounts of foreign cells or DNA, referred to as microchimerism, occurs primarily through maternal-fetal exchange during pregnancy. Microchimerism can persist long-term and has been associated with both beneficial and adverse human health outcomes. Quantitative microchimerism data present challenges for statistical analysis, including a skewed distribution, excess zero values, and occasional large values. Methods for comparing microchimerism levels across groups while controlling for covariates are not well established...

The current study aims at a comprehensive risk characterization of bisphenol A (BPA) supported by an integrated exposure modelling framework that comprises far field and near field exposure modelling coupled to a dynamic lifetime PBTK model. Exposure analysis was done on European data of BPA food residues and human biomonitoring (HBM). The latter were further assimilated through an advanced exposure reconstruction modelling framework to estimate the corresponding external and internal systemic dose of BPA and its metabolites...

Open surgery and arthroscopy for the treatment of synovial chondromatosis (SC) of the temporomandibular joint (TMJ) have their advantages and disadvantages. The aim of this study was to report the application and results of the combined use of these two methods in the treatment of SC and the indications for use. A total of 36 patients with magnetic resonance imaging (MRI) confirmation of SC, treated from 2010 to 2015, were included. Patients with tumours in the upper articular cavity and with the extended margin of the medial groove still in-between the medial crest of the condyle and infratemporal space on coronal MRI were selected to undergo open surgery with the assistance of arthroscopy to clear the loose bodies and affected synovium...

The aim of this paper is to assess recycling process window of ABS (Acrylonitrile-Butadiene-Styrene) and HIPS (High impact Polystyrene) from WEEE (waste from electrical and electronic equipment) through a final properties/structure screening study on their blends. Main motivation is to evaluate which amount of one plastic WEEE can be included into the other at least keeping their properties. In this sense, a wider margin of error during sorting could be admitted to obtain recycling materials with similar technological application of recycled ABS and HIPS by themselves...

BACKGROUND: The creation of a superior palpebral crease has been the most popular plastic surgery procedure in Asians for several decades. The most important criterion for judging the success of this procedure is the achievement of the desired size and shape of this crease or the perfect crease width. However, the determinants of crease width remain unclear, which may account for the high rate of unsatisfactory results. METHODS: Standard images were used to study the anatomic parameters, including crease width, crease height, and upper eyelid movement distance (ULMD) at the midpupillary axis, of the inherent double eyelid crease in 32 Chinese women aged 19-26 years...

BACKGROUND: Computational models in biology are characterized by a large degree of uncertainty. This uncertainty can be analyzed with Bayesian statistics, however, the sampling algorithms that are frequently used for calculating Bayesian statistical estimates are computationally demanding, and each algorithm has unique advantages and disadvantages. It is typically unclear, before starting an analysis, which algorithm will perform well on a given computational model. RESULTS: We present BCM, a toolkit for the Bayesian analysis of Computational Models using samplers...

BACKGROUND: Ecological momentary assessment (EMA) of mental health symptoms may influence the symptoms that it measures, i.e. assessment reactivity. In the field of depression, EMA reactivity has received little attention. We aim to investigate whether EMA of depressive symptoms induces assessment reactivity. Reactivity will be operationalised as an effect of EMA on depressive symptoms measured by a retrospective questionnaire, and, secondly, as a change in response rate and variance of the EMA ratings...

Men who have sex with men (MSM) are an important risk group for human immunodeficiency virus (HIV) and at high risk of herpesvirus infection. However, limited information on epidemiologic patterns of HHV8 and HSV2 among MSM is available in mainland China. A cross-sectional study of 486 participants was performed in Shanghai, China from January 2013-December 2014 to explore epidemiologic features of HHV8 and HSV2 among MSM. Serum samples were collected and tested for HHV8 by immunofluoresence assay and HSV2 antibodies by ELISA...

A series of triazole-based small molecules that mimic FTY720-mediated anticancer activity but minimize its immunosuppressive effect have been produced. SPS-7 is the most effective derivative displaying higher activity than FTY720 in anti-proliferation against human hormone-refractory prostate cancer (HRPC). It induced G1 arrest of cell cycle and subsequent apoptosis in thymidine block-mediated synchronization model. The data were supported by a decrease of cyclin D1 expression, a dramatic increase of p21 expression and an associated decrease in RB phosphorylation...
