Objective: The source of residual HIV viremia is highly debated and its potential relationship with the HIV reservoir has not been clarified. Herein, we analysed the cell-associated HIV-DNA content in two important cell compartments of the HIV reservoir, resting CD4+ T memory (Trm) and peripheral T follicular helper (pTfh) cells, and the association with the residual HIV viremia in individuals with spontaneous HIV replication control (elite controllers, EC group) and in individuals with antiretroviral therapy (ART)-mediated HIV replication control (cART group).
Design: A cross-sectional study.
The HIV reservoir is the main barrier to eradicating HIV infection, and resting memory CD4 T (Trm) cells are one of the most relevant cellular component harboring latent proviruses. This is the first study analyzing the transcriptional profile of Trm cells, in two well-characterized groups of HIV patients with distinct mechanisms of viral replication control (spontaneous versus treatment-induced). We use a systems biology approach to unravel subtle but important differences in the molecular mechanisms operating at the cellular level that could be associated with the host's ability to control virus replication and persistence.

Method: In this observational study, we describe the main characteristics and data from electrocardiogram, chest X-ray, echocardiogram and cardiac magnetic resonance imaging (MRI) of 141 patients with Chagas' disease attended in a tertiary university hospital in Madrid from 2009 to 2018.
Objective: Over the past decade, overweight and childhood obesity has increased markedly, and children are therefore dissatisfied with their body image due to the beauty canons established in today's society. The purpose of this paper was to examine the level of obesity and body satisfaction based on sociodemographic and contextual variables of the educational center as well as the relationship they have with the physical self-concept on a sample of primary school and compulsory secondary school students city of Badajoz.
Methods: The instruments used in the study were the questionnaire of Physical Self-concept (CAF) and questionnaire of Bodily Silhouettes.
A recent study has pointed out to CD32a as a potential biomarker of HIV-persistent CD4 cells. We have characterized the level and phenotype of CD32+ cells contained in different subsets of CD4 T-cells and its potential correlation with level of total HIV-DNA in thirty HIV patients (10 typical progressors naïve for cART, 10 cART-suppressed patients, and 10 elite controllers). Total HIV-DNA was quantified in different subsets of CD4 T-cells: Trm and pTfh cells.

All of them have been classified as LGV serovar L2b, mainly occurring in human immunodeficiency virus (HIV)-infected men who have had sex with men (MSM). We describe a series of 26 diagnosed cases of LGV proctitis in downtown Madrid, Spain, in 2014, after implementing routine diagnostic procedures for this disease in symptomatic MSM.

Material And Methods: Review of CM cases in a university hospital. The diagnosis was determined by isolation of Cryptococcus neoformans in cerebrospinal fluid.
Endocarditis due to Corynebacterium striatum has been rarely reported. A 78-year-old patient developed pacemaker endocarditis caused by multidrug-resistant C. striatum, complicated by vertebral osteomyelitis and epidural abscess.

To determine the mechanisms that are driving this lack of prevention is important to reverse the trend.
Patients And Methods: An anonymous, voluntary and self-reporting questionnaire was completed by HIV+ MSM patients who were seen in a hospital clinic, with the aim of finding out the sexual risk practices and behaviour, as well as their perceptions and assessment as regards this risk.

Background: Our aim is analyze the epidemiological factors of enteric fever in Madrid (Spain) over the last 30 years.
Material And Methods: A retrospective review was conducted on cases of typhoid and paratyphoid fever studied in the Fundación Jiménez Díaz (Madrid) between 1980 and 2010. Two similar periods in time were studied (P1: 1980-1993; P2: 1994-2010).
The frequency of autopsies appears to be declining, and the usefulness has been challenged. We reviewed cases of autopsied active infective endocarditis (IE) during 2 periods based on the availability of high-tech 2-dimensional echocardiograms: Period 1 (P1) included 40 cases studied from 1970 to 1985, and Period 2 (P2) included 28 cases seen from 1986 to 2008--that is, before and after the introduction of echocardiograms in our institution. We conducted the study to reassess the pathology of IE and to determine how frequently diagnosis is not made during life.

Lung infectious diseases occurring in patients with congenital immunodeficiency and patients on treatment with biologic anti-inflammatory compounds are discussed. Understanding of the complex relationships between the immune system and microbes is of paramount importance for timely diagnosis and successful treatment of lung infectious diseases in this group of immunocompromised hosts.

Objectives: To describe the clinical presentation of a large number of Q fever endocarditis (QFE) and its management considering the role of serology.
Patients And Methods: Eighty-three patients with definite QFE (56 native and 27 prosthetic valve) with a long-term follow-up after stopping treatment (median: 48 months) were included. Final outcome (cure or relapse) was compared according with the serological titre at the end of therapy: less than 1:400 of phase I Ig G antibodies by indirect immunofluorescence (group 1, N=23) or more than 1:400 (group 2, N=30).
Skin manifestations of immune reconstitution inflammatory syndrome in response to highly active antiretroviral therapy may account for up to 50% of the clinical presentations in this syndrome. Viable or dying infective antigens, host antigens, tumoral antigens, and others may target immune reconstitution inflammatory syndrome, resulting in a wide spectrum of clinical manifestations. We describe a 26-year-old HIV-infected man who had started highly active antiretroviral therapy a few months earlier.

We report an unusual case of pulmonary schistosomiasis in a traveler to Mali that was diagnosed 16 months after primary infection, one month after she finished chemotherapy for a malignant tumor. Serologic analysis showed marked eosinophilia. Our case emphasizes the need to detect parasitic infections in cancer patients with unexplained eosinophilia, particularly in immigrants and travelers to tropical countries.
