Re-emergence of HIV Infection and Syphilis Among Men Who Have Sex with Men
2012
Sexual activity has been shown to be the primary mode of transmission for several important viral and bacterial infections among men who have sex with men (MSM) throughout the world and therefore sexually transmitted infections (STIs) are still one of major public health problem worldwide. Since the earliest days of the human immunodeficiency virus (HIV) epidemic MSM have been profoundly affected by the disease; by the time the first AIDS cases were reported in the early 1980s, HIV had already spread widely among homosexual and drug-user communities. In western Europe, has been estimated that HIV incidence peaked around 1983 among MSM and in 1987-88 among injecting drug users, with 120.000 …

In COVID-19 related infodemic, social media becomes a medium for wrongdoers to spread rumors, fake news, hoaxes, conspiracies, astroturf memes, clickbait, satire, smear campaigns, and other forms of deception. It puts a tremendous strain on society by damaging reputation, public trust, freedom of expression, journalism, justice, truth, and democracy. Therefore, it is of paramount importance to detect and contain unreliable information. Multiple techniques have been proposed to detect fake news propagation in tweets based on tweets content, propagation on the network of users, and the profile of the news generators. Generating human-like content allows deceiving content-based methods. Networ…
Autoeficacia en la prevención sexual del Sida: la influencia del género
2013
Title: Self-efficacy in AIDS sexual prevention: influence of gender. Abstract: The scientific literature suggests that a low self-efficacy for con- dom use may be related to many risky behaviors for HIV transmission in young people. We analyze the self-efficacy of condom use among youth, the existence of gender differences and the relationship with other relevant variables in HIV prevention. The "Self-Efficacy Condom Use Subscale", included in the AIDS Prevention Questionnaire (Ballester, Gil and Gimenez, 2007), was administrated to 3540 university students (50.9% women, 49.1% men). The results showed that the sample obtained medi- um-high scores on self-efficacy, showing the lowest scores …
Características sociales y clínicas de un grupo de madres infectadas por VIH en Valencia: influencia de la drogadicción parenteral
2000
Resumen Objetivo Al principio de conocerse la infeccion por el virus de la inmunodeficiencia humana (VIH), la causa mas importante de su transmision en las mujeres occidentales fue el consumo de drogas por via parenteral. El objetivo de nuestro trabajo consistio en describir las principales caracteristicas sociales y clinicas de un grupo de madres seropositivas, y en analizar su relacion potencial con el uso intravenoso de drogas. Metodos Realizamos un estudio observacional prospectivo con 220 mujeres infectadas por VIH que presentaban la particularidad de haber dado a luz ninos con riesgo de infeccion. Se incluyeron todas las madres reclutadas en la Unidad VIH de un hospital de Valencia qu…
Laparoscopic lymph node dissection should be performed before fertility preserving treatment of patients with cervical cancer
2012
Objective: The aim of this study is to assess our results of treatment of women with stage I cervical cancer > 2 cm in diameter seeking fertility preservation. Treatment consisted of Laparoscopic Pelvic and Paraaortic Lymphadenectomy (LPPLND), and when no nodal metastasis was detected, neoadjuvant chemotherapy (NACT) followed by radical vaginal trachelectomy (RVT). Patients with positive lymph nodes underwent primary chemoradiation. Methods: A cohort of women younger than 40 years of age with stage I disease > 2 cm who underwent LPPLND and either NACT and RVT or chemoradiation. Oncological outcome was evaluated prospectively. Results: Eighteen women were eligible for this study. Twelve (67%…
Clinical Recommendation Radical Trachelectomy for Fertility Preservation in Patients With Early-Stage Cervical Cancer
2012
Radical trachelectomy (RT) is a fertility-sparing procedure with the aim to provide adequate oncological safety to patients with cervical cancer while preserving their fertility. In the current review, indications, development of the procedure, technical aspects, preoperative and postoperative management, and oncological, fertility, and obstetric outcomes are discussed and studied with respect to whether the procedure is performed abdominally or vaginally. Complications of RT, staging, and more conservative alternatives to RT are discussed as well. A systematic MEDLINE search was performed, which yielded 218 articles, of which 75 were selected for further analysis based on the number of pat…
Perioperative morbidity and rate of upstaging after laparoscopic staging for patients with locally advanced cervical cancer: results of a prospective…
2015
Objective The International Federation of Gynecology and Obstetrics (FIGO) staging for cervical cancer is based on clinical examination. Previous studies have demonstrated significant upstaging with surgical staging. However, no randomized trial has ever shown a survival benefit when radiation combined with chemoradiation (RCTX) is modified according to surgical staging. The objective of the study was to evaluate the feasibility and outcomes of surgical staging prior to radical RCTX treatment among patients with locally advanced cervical cancer in the setting of a larger, prospective, randomized study (the Uterus-11 study of the German Gynecologic Oncology Group). Study Design Between 2009 …
Quantitative importance of staminodes for female reproductive success inParnassia palustrisunder contrasting environmental conditions
2003
The five sterile stamens, or staminodes, in Parnassia palustris act both as false and as true nectaries. They attract pollinators with their conspicuous, but non-rewarding tips, and also produce nectar at the base. We removed staminodes experimentally and compared pollinator visitation rate and duration and seed set in flowers with and without staminodes in two different populations. We also examined the relative importance of the staminode size to other plant traits. Finally, we bagged, emasculated, and supplementary cross-pollinated flowers to determine the pollination strategy and whether reproduction was limited by pollen availability. Flowers in both populations were highly dependent o…
Funcionamiento neuropsicológico en drogodependientes VIH/SIDA inmunodeprimidos: Importancia de la fase de la infección y del consumo de drogas
2000
Todavía no disponemos de factores de riesgo definitivos que permitan predecir la naturaleza y magnitud de las complicaciones neuropsicológicas asociadas a la infección por VIH. Con este trabajo nos planteamos estudiar la naturaleza del deterioro neuropsicológico asociado al VIH en drogodependientes con historia de consumo de drogas por vía intravenosa inmunodeprimidos, así como determinar la influencia que tienen sobre el mismo la fase clínica de la infección (asintomáticolSIDA) y el consumo de drogas. Para ello hemos utilizado una muestra de 20 drogodependientes voluntarios en distintas fases de la infección (A3 y C3). En cada uno de estos grupos la mitad de los sujetos se encuentra en abs…
Kawasaki disease in Sicily: clinical description and markers of disease severity
2016
Background: Kawasaki disease (KD) is an acute systemic vasculitis of small and middle size arteries; 15-25 % of untreated patients and 5 % of patients treated with intravenous immunoglobulin (IVIG) develop coronary artery lesions (CAL). Many studies tried to find the most effective treatment in the management of resistant KD and to select the risk factors for CAL. Our data are assessed on children from west Sicily, characterized by a genetic heterogeneity. Methods: We studied the clinical data of 70 KD Sicilian children (36 males: 51 %; 34 females: 49 %), analysed retrospectively, including: demographic and laboratory parameters; echocardiographic findings at diagnosis, at 2, 6 and 8 weeks,…
