CONTEXT AND OBJECTIVE: A search in the SciELO and PubMed databases showed few studies on human immunodeficiency virus (HIV) positive individuals in long-term care institutions (LTCIs), thus prompting the present study. The aim of this study was to ascertain whether there were any HIV-positive individuals in LTCIs for the elderly. DESIGN AND SETTING: Cross-sectional study in which the Hospital Infection Control Committee (HICC) of a 405-bed LTCI was consulted. METHODS: The medical records of 405 individuals interned in the LTCI who had been tested for HIV infection were requested for analysis of the following variables: [1] age and gender; [2] length of stay at LTCI (months); [3] causes and diagnoses on admission to LTCI according to International Classification of Diseases, 10th edition; [4] date of HIV diagnosis; [5] seropositivity for syphilis and hepatitis B and C viruses; [6] medications used at last prescription in medical file; and [7] mean CD4 lymphocyte count based on: total lymphocyte count/6 and total lymphocyte count x 0...

OBJECTIVES: It has been hypothesized that BK polyomavirus infection leads to nephropathy in kidney transplant patients via various plausible mechanisms, such as stimulation of chemokines. The CXCL11 gene may also play a role in BK polyomavirus-associated nephropathy. Our aim was to compare expression levels of CXCL11 in BK polyomavirus-infected versus noninfected kidney transplant patients with nephropathy and healthy controls. MATERIALS AND METHODS: We performed a cross-sectional study of 58 kidney transplant patients with the risk of BK polyomavirus infection; these patients were subgrouped as BK polyomavirus-infected (23 patients) and noninfected (35 patients)...

Infections arising in hospitalized patients, particularly those who have undergone surgery and are reliant on receiving treatment through biomedical devices, continue to be a rising concern. It is well known that aqueous mixtures of oppositely charged surfactant and polymer molecules can self-assemble to form liquid crystalline structures primarily via electrostatically-driven interactions which have demonstrated great potential as tailored release nanomaterials. Colistin is a re-emerging antibiotic used against multidrug-resistant Gram negative bacteria...

The pathogenesis of classical Hodgkin lymphoma (cHL) is still enigmatic, largely because its tumor cells, the so-called Hodgkin and Reed-Stenberg (HRS) cells, invariably reside in a prominent reactive microenvironment, are rare and therefore difficult to analyze. On the other hand, the broadly investigated cHL-derived cell lines are not unequivocally considered as suitable and representative models for this puzzling disease. Based on current knowledge, it appears that the cross talk between the tumour cells and the reactive infiltrate of the microenvironment is complex and that multiple mechanisms occur, making cHL a very heterogeneous disease...

African and Caribbean Black (ACB) women in Canada are disproportionately impacted by new HIV infections. ACB women's HIV vulnerabilty is shaped by contexts of stigma and discrimination. HIV-related stigma compromises quality of life (QOL) among women living with HIV (WLWH), yet scant research has examined concomitant effects of racial discrimination and HIV-related stigma on QOL. We used data from a cross-sectional survey with ACB WLWH in Ontario (n=173) to test a conceptual model of pathways between HIV-related stigma, racial discrimination, depression, social support and QOL...

Among all cancers, the incidence of nasopharyngeal carcinoma (NPC) is quite high in the endemic regions. NPC is a head and neck cancer with poor survival rate, and is rare throughout most of the world but common in certain geographic areas, like southern Asia and some regions of North East India (Nagaland, Manipur, and Mizoram). A clear understanding of its etiology is still lacking, but NPC is widely suspected to be the result of both genetic susceptibility and exposure to environmental factors or Epstein-Barr virus infection...

The insulin-like growth factor (IGF) receptor (IGF-IR) is necessary for IGF signalling and has essential roles in cellular growth. In teleost fish, two distinct IGF-IR duplicates are conserved called IGF-IRa and IGF-IRb. However, while a salmonid-specific whole genome duplication (ssWGD) is known to have expanded several key genes within the IGF axis, its impact on the IGF-IR repertoire remains unresolved. Using bioinformatic and phylogenetic approaches, we establish that salmonids retain two IGF-IRa paralogues from ssWGD and a single IGF-IRb copy...
