Insulin Resistance and the Cardiometabolic Syndrome in HIV Infection

2009

Highly active antiretroviral therapy (HAART) has dramatically improved the prognosis of HIV-positive patients. However, long-term adverse effects of this therapy include dyslipidemia, insulin resistance (IR), changes in body fat distribution (lipodystrophy), and cardiometabolic syndrome (CMS). IR in HIV-positive patients does not seem to represent a significant independent risk factor for the development of cardiovascular disease; nevertheless, the association with other metabolic complications (dyslipidemia, fat redistribution) and CMS may increase the risk of type 2 diabetes and cardiovascular disease. The use of nucleoside analogue reverse transcriptase inhibitors is associated with the …

The Efficacy of Rotary, Reciprocating, and Combined Non-Surgical Endodontic Retreatment Techniques in Removing a Carrier-Based Root Canal Filling Mat…

2020

The aim of this study is to analyze and compare the efficacy of three non-surgical endodontic retreatment techniques in removing a carrier-based root canal filling material from straight root canal systems. The study was performed on 99 single-rooted extracted teeth using the ProTaper Gold endodontic rotary system up to the F2 file (Dentsply Maillefer, Baillagues, Switzerland), which were sealed with GuttaCore (Dentsply Maillefer, Ballaigues, Switzerland) and AH plus epoxy resin sealer (Dentsply DeTrey, Konstanz, Germany) and randomly assigned to the following non-surgical retreatment techniques: ProTaper Retreatment endodontic rotary instruments (D1&ndash

Increased risk for cervical disease progression of French women infected with the human papillomavirus type 16 E6-350G variant.

2006

Abstract To test the significance of human papillomavirus (HPV) type 16 and HPV16 E6 variants as risk factors for viral persistence and progression to high-grade lesion, we did a nested case-control study within a cohort study of >15,000 Caucasian French women. Three groups infected with high-risk HPV were compared: (a) women with cleared infection (controls, n = 201), (b) women with persistent infection (cases, n = 87), and (c) women who progressed into high-grade lesion (cases, n = 58). Women with persistent HPV infection and those that progressed into high-grade lesions were likelier to harbor HPV16 than other high-risk HPV types [odds ratio (OR), 2.4; 95% confidence interval (95%…

Human papilloma virus genotypes in dysplasia and epithelial hyperplasia of oral cavity using the luminex xmap technology. A multicenter study

2019

Background Oral cancer associated with high risk (HPV-HR) human papilloma virus (HPV) has been increasing. HPV-HR has been associated with epithelial dysplasia, however, little information exists on its frequency in epithelial hyperplasia lesions. The aim of this study is to compare HPV genotypes in dysplastic and hyperplastic lesions of oral cavity. Material and Methods Two hundred and fifty oral lesions: 131 dysplasia and 119 hyperplasia from two regions of Colombia were evaluated. One hundred seventy-four coming from urban area and 104 from a high risk population to oral cancer from a rural area. HPV was identified by qPCR and Twenty-four HPVs genotypes were evaluated by Luminex® technol…

Advantage of eradication therapy for Helicobacter pylori before kidney transplantation in uremic patients.

2007

ABSTRACT From January 1999 to February 2007, 61 end-stage renal disease (ESRD) candidates for kidney transplantation underwent an esophagogastroduodenoscopy (EGDS) to detect Helicobacter pylori (HP). We correlated treatment for HP before transplantation and upper digestive tract hemorrhagic complications and possible recurrence of peptic disease posttransplantation. The 32 (52.4%) HP-Positive cases were divided into 2 groups: (1) 17 patients who underwent treatment for the eradication of the infection with 40 mg/d omeprazole for 4 weeks, 500 mg claritromycin twice daily for 7 days, and 2 g/d amoxicillin for 7 days; and (2) 15 untreated patients. No significant differences were found in the …

Helicobacter pyloriand Non-malignant Diseases

2008

In 2007 Helicobacter pylori research continued to deal with some controversies raised in the last decade. The main problems remain unsolved: peptic ulcer disease negative for H. pylori, synergism of H. pylori infection and aspirin and other nonsteroidal anti-inflammatory drugs or cyclooxygenase 2 specific inhibitors, the role of H. pylori eradication in uninvestigated and nonulcer dyspepsia, and the possible protective effect of H. pylori infection against gastroesophageal reflux disease and its complications such as Barrett's esophagus and adenocarcinoma. The incidence and prevalence of peptic ulcer disease as well as ulcer-related mortality are continuing to decline all over the world. Th…

Molecular Surveillance of HIV-1 in Madrid, Spain: a Phylogeographic Analysis ▿

2011

ABSTRACT The molecular epidemiology of HIV-1 is constantly changing, mainly as a result of human migratory flows and the high adaptive ability of the virus. In recent years, Spain has become one of Europe's main destinations for immigrants and one of the western European countries with the highest rates of HIV-positive patients. Using a phylogeographic approach, we have analyzed the relationship between HIV-1 variants detected in immigrant and native populations of the urban area of Madrid. Our project was based on two coincidental facts. First, resistance tests were extended to naïve and newly diagnosed patients, and second, the Spanish government legislated the provision of legal status t…

Sequential evolution of genotype GII.4 norovirus variants causing gastroenteritis outbreaks from 2001 to 2006 in Eastern Spain.

2008

Noroviruses are the most common cause of outbreaks of viral gastroenteritis worldwide. Norovirus outbreaks were surveyed in Catalonia and the region of Valencia (Eastern Spain) between January 2001 and December 2006 as part of the European Union funded network "Food-borne viruses in Europe". During this time the etiology and epidemiological features of 194 outbreaks of acute non-bacterial gastroenteritis were investigated and norovirus was identified as causing 169 (87.1%) of them. Molecular epidemiology of viral strains was studied by RT-PCR and sequencing part of the RNA polymerase gene in ORF1 from 153 outbreak strains. The most commonly identified norovirus genotype was GII.4 (71.9% of …

Ethics and the treatment as prevention strategy among transgender women living with HIV in Argentina

2020

While numerous ethical concerns have been voiced regarding HIV service scale-up strategies targeting key populations, few studies have examined these from the perspective of affected groups. This study therefore sought to understand transgender women's experiences and perspectives of targeted HIV services scale-up in the context of Argentina's Treatment as Prevention strategy. In 2016, 25 purposively selected transgender women living with HIV were interviewed by a peer research associate. Interviews were audio recorded, transcribed verbatim and analysed using participatory coding techniques. Findings suggest that procedures around informed consent, including the provision of full informatio…
