The incidence of breast cancer is continuously increasing worldwide, as influenced by many factors that act synergistically. In the last decade there was an increasing interest in the possible viral etiology of human breast cancer. Since then, many viruses have been associated with this disease (murine mammary tumor virus, MMTV; Epstein-Barr virus, EBV; and human papillomavirus, HPV). Recently, BLV has been identified in human breast cancers giving rise to the hypothesis that it could be one of the causative agents of this condition...

IgA vasculitis is a small-vessel vasculitis mediated by immune complexes. In clinical terms, it is characterized by palpable purpura in the lower limbs, joint involvement in the form of arthralgia or arthritis, and gastrointestinal and renal involvement (this will mark a poorer prognosis in adults). Infectious processes, mainly in the upper respiratory tract, are frequently found to be triggers. On the other hand, human immunodeficiency virus (HIV) causes immune dysfunction, which triggers hypergammaglobulinemia and can trigger autoimmune disorders...

This paper aims to analyze the process of medicalization in current societies, starting from the description of the way in which medicine gradually appropriated various aspects of everyday life that were once part of the life cycle of people. At the theoretical level, we are based on authors such as Descola and Latour, who problematize the dichotomy between Nature and Culture, and propose the need to think from a superior episteme. Methodologically, this theoretical proposal enables an analysis of the medicalization that can illuminate what is hidden in the discourse and biomedical practices: the sociocultural, political and economic processes that are part of these "objects" of Medicine...

We focused on the analysis of biological parameters of two different abundant populations of Dipetalogaster maximus (Uhler) (Hemiptera: Reduviidae: Triatominae) from northwestern Mexico. The biological parameters were related to hatching of eggs, life cycle, and meal needed for molting by each instar of two populations from environmentally similar areas (El Fandango and San Dionisio) with a similar number of available hosts as blood meal sources. The D. maximus populations from the two locations were evaluated and compared...

Background: To date, few studies have focused on the clinical and allergic characteristics of asthma in the elderly, defined as asthma in people aged 60 or over. Thus, we propose to identify and study the clinical and allergic characteristics and comorbidities of patients with asthma among the elderly. Methods: A retrospective, observational, descriptive study was developed in five clinics and hospitals in Argentina. Allergy Physicians analyzed their patients' medical records in 2014 and included those adults over the age of 60, who had been diagnosed with asthma according to the GINA guidelines...

Bartonellae are emerging blood-borne bacteria that have been recovered from a wide range of mammalian species and arthropod vectors around the world. Bats are now recognized as a potential wildlife reservoir for a diverse number of Bartonella species, including the zoonotic Candidatus B. mayotimonensis. These bat-borne Bartonella species have also been detected in the obligate ectoparasites of bats, such as blood-feeding flies, which could transmit these bacteria within bat populations. To better understand this potential for transmission, we investigated the relatedness between Bartonella detected or isolated from bat hosts sampled in Mexico and their ectoparasites...

BACKGROUND: Pulmonary aspiration of gastric contents is associated with significant perioperative morbidity and mortality. Previous studies have investigated the validity, reliability, and possible clinical impact of gastric ultrasound for the assessment of gastric content at the bedside. In the present study, we examined the accuracy (evaluated as sensitivity, specificity, and likelihood ratios) of point-of-care gastric ultrasound to detect a "full stomach" in a simulated scenario of clinical equipoise...

BACKGROUND: Growth conditions that bring about stress on Phaffia rhodozyma cells encourage the synthesis of astaxanthin, an antioxidant carotenoid, which protects cells against oxidative damage. Using P. rhodozyma cultures performed with and without copper limitation, we examined the kinetics of astaxanthin synthesis along with the expression of asy, the key astaxanthin synthesis gene, as well as aox, which encodes an alternative oxidase protein. RESULTS: Copper deficiency had a detrimental effect on the rates of oxygen consumption and ethanol reassimilation at the diauxic shift...

Normal schools in Mexico train teachers for basic level education. Classified as Higher Education Institutions, part of their mandate is to conduct scientific research to improve educational quality. Currently, normal school students can meet graduation requirements by either writing a thesis or reporting on professional practice using Participatory Action Research (PAR). Teachers at normal schools have only limited experience in conducting and supervising PAR projects. With the aim of analyzing the situation and addressing this paradox, we used PAR to develop a plan to train normal school teachers in application of PAR methodology...

Lack of condom use among youth is a major contributor to the spread of sexually transmitted infections (STIs) including HIV/AIDS, which has lifelong deleterious health consequences. College students (N = 262) completed the Sexual Probability Discounting Task in which participants reported their likelihood of condom use under various probabilities of contracting an STI. Each participant completed the task in regard to different STIs including HIV/AIDS and different partners. Results showed that the likelihood of condom-protected sex generally decreased as HIV/AIDS and other STI contraction became less probable...

Infection with Trypanosoma cruzi in women at reproductive age is associated with congenital transmission and adverse pregnancy outcome. The placenta is a key barrier to infection. We characterized gene expression profiles of term placental environment from T. cruzi seropositive (SP) and seronegative (SN) mothers performing RNA-seq. Nine pools of placental RNA paired samples were used: three from SN and six from SP tissues. Each pool consisted of female/male newborns and vaginal/caesarean deliveries binomials...

Gestational stress is believed to increase the risk of pregnancy failure and perinatal and adult morbidity and mortality in both the mother and her child or children. However, some contradictions might arise from methodological issues or even from differences in the philosophical grounds that guide the studies on gestational stress. Biased perspectives could lead us to use and/or design inadequate/incomplete panels of biochemical determinations and/or psychological instruments to diagnose it accurately during pregnancy, a psychoneuroimmune-endocrine state in which allostatic loads may be significant...

Social impairments are a hallmark of Autism Spectrum Disorders (ASD), but empirical evidence for early brain network alterations in response to social stimuli is scant in ASD. We recorded the gaze patterns and brain activity of toddlers with ASD and their typically developing peers while they explored dynamic social scenes. Directed functional connectivity analyses based on electrical source imaging revealed frequency specific network atypicalities in the theta and alpha frequency bands, manifesting as alterations in both the driving and the connections from key nodes of the social brain associated with autism...

Degradation of the environment by agriculture affects the persistence and health of the amphibian populations. Characteristics related to reproduction of anuran can be used to evaluate the status of populations and as endpoints in environmental health assessment. In this in situ study the aspects related to the amplexus and ovipositions of the bioindicator species Rhinella arenarum that inhabits agroecosystems were analyzed. The hypothesis of this study is that perturbations of agroecosystems have a negative impact on the size of reproductive adults, on the size of ovipositions and eggs, and on the survival of eggs and embryos...

Diabetes is a common cardiovascular risk factor in psoriatic arthritis (PsA). Although the prevalence of diabetes is high, the factors associated with it in PsA are poorly understood. We aimed to analyse the prevalence of type II diabetes and diabetes-associated factors in a hospital-based population with PsA. This cross-sectional study included 340 consecutive patients attended in a tertiary care hospital. The prevalence of diabetes was compared to that of 600 outpatients without inflammatory conditions. To analyse diabetes-associated factors, odds ratio (OR) values were calculated by conditional logistic regression analysis...

Adolescence is a vulnerable period for the development of depressive disorders. Recent research has demonstrated the importance of distress tolerance in the onset and maintenance of depression during adulthood; however, little is known about its role in predicting depressive symptoms among adolescents. The current study examines the effect of distress tolerance and co-occurring negative life events on the developmental trajectory of depressive symptoms from middle to late adolescence. Our sample included 117 adolescent boys and girls (44...
