Background: Nonalcoholic fatty liver disease (NAFLD) is an increasing concern for people living with HIV (PLWH). However, information on the impact of NAFLD on the prognosis of PLWH is very scarce.

Aims: To investigate the influence of NAFLD on the overall and liver-related mortality in PLWH.

Zebrafish (Danio rerio) are a compelling model for studying lymphocytes because zebrafish and humans have similar adaptive immune systems, including their lymphocytes. Antibodies that recognize zebrafish proteins are sparse, so many investigators use transgenic, lymphocyte-specific fluorophore-labeled lines. Human and zebrafish lymphocyte types are conserved, but many aspects of zebrafish lymphocyte biology remain uninvestigated, including lymphocytes in peripheral tissues, like epidermis.

The prevalence of active hepatitis C virus (HCV) infection is higher in hospital emergency departments (EDs) than in the general population. Numerous patients who seek emergency care are unaware that they have detectable viremia, yet they fall outside established ED protocols for HCV screening. Often they belong to groups with difficult access to health care who use the ED as their point of entry to the system.

Background: In patients with hepatitis C virus (HCV) chronic infection and advanced liver disease, the impact of human immunodeficiency virus (HIV) coinfection on the clinical outcome after sustained virological response (SVR) has not been sufficiently clarified. The aim of this study was to compare the mortality after SVR of patients bearing HCV chronic infection and advanced liver fibrosis, with and without HIV-coinfection after a prolonged follow-up.

Methods: This was a prospective multicenter cohort study including individuals with HIV/HCV-coinfection and patients with HCV-monoinfection from Spain, fulfilling: 1) Liver stiffness (LS) ≥9.

Background: Non-AIDS defining malignancies present a growing challenge for persons with HIV (PWH), yet tailored interventions for timely cancer diagnosis are lacking. The Spanish IMPAC-Neo protocol was designed to compare two comprehensive cancer screening strategies integrated into routine HIV care. This study reports baseline data on the prevalence and types of precancerous lesions and early-stage cancer among participants at enrolment.

The design of photovoltaic modules for vehicle-integrated photovoltaics (VIPVs) must consider specific operating conditions like partial shading. Module cell interconnection topology must demonstrate resilience to such conditions to maximize energy generation without compromising shadow-free performance, manufacturing complexity, or cost. This study presents a modeling tool for VIPV, calculating effective irradiance on the VIPV surface using Light Detection And Ranging (LiDAR) point clouds to estimate the direct component and sky images for the diffuse irradiance.

Hydrotherapy, including the use of therapeutic showers and bathtubs, has been studied for its potential benefits in labor pain management. Previous research has indicated that hydrotherapy can alleviate pain, but comparative studies between therapeutic showers and bathtubs are scarce. : This study aims to compare the effects of therapeutic showers and bathtubs on pain perception, labor duration, use of epidural analgesia, and maternal and neonatal outcomes during labor.

We assessed the prevalence and factors associated with HIV-infected patients' interest in trying long-acting injectable antiretroviral treatment (LAI-ART) along with its expected benefits and concerns, and evaluated physicians' opinions about LAI-ART. This study was set within the multi-center prospective CoRIS cohort, comprising HIV-positive adults, naïve to antiretroviral treatment (ART) at study entry, recruited from 2004 onward in 48 centers in Spain. In June 2022, we conducted a 2-day cross-sectional survey among patients across 34 CoRIS centers and sent an online questionnaire to all physicians prescribing ART in 39 CoRIS centers.

Background: Killip-Kimball classification has been used for estimating death risk in patients suffering acute myocardial infarction (AMI). Killip-Kimball stage IV corresponds to cardiogenic shock. However, the Society for Cardiovascular Angiography and Interventions (SCAI) classification provides a more precise tool to classify patients according to shock severity.

The thymus is the site of T lymphocyte development and T cell education to recognize foreign, but not self, Ags. B cells also reside and develop in the thymus, although their functions are less clear. During "thymic involution," a process of lymphoid atrophy and adipose replacement linked to sexual maturation, thymocytes decline.

Objective: The incidence of type 2 diabetes mellitus (T2DM) has risen dramatically. Among people living with HIV (PLHIV), chronic disease (now >15 cases/1000 in the general population worldwide) and long-term exposure to antiretroviral therapy (ART) can alter metabolic processes early, favoring insulin resistance and T2DM. We retrospectively studied the incidence of T2DM and associated factors in the Cohort of the Spanish AIDS Research Network, a prospective cohort of PLHIV enrolled at diagnosis and before initiation of ART.

Article Synopsis
  • - The study investigates how HIV affects the severity of mpox outcomes in a large group of patients from 18 hospitals in Spain, focusing on factors like duration of illness and the presence of complications.
  • - Out of 1,823 patients with PCR-confirmed mpox, around 43% were people living with HIV, with a significant portion having uncontrolled viral loads, leading to higher rates of long or complicated mpox.
  • - The findings suggest that individuals with uncontrolled HIV are at increased risk for severe mpox complications, highlighting the need for timely HIV testing and immediate antiretroviral therapy for those diagnosed.

Article Synopsis
  • - Microglial dysfunction is linked to Alzheimer's disease (AD), with a focus on a variant affecting the SIRPβ1 receptor that regulates the clearance of amyloid-β (Aβ).
  • - The study found that a specific insertion in the SIRPβ1 gene alters protein function, increasing the risk of AD and affecting cognitive decline rates in patients with mild cognitive impairment.
  • - Results suggest that this SIRPβ1 variant could influence microglial responses to Aβ and may serve as a potential target for treatment strategies that involve the TREM2-TYROBP pathway.

Pain diagnoses in the 10th version of the International Classification of Diseases (ICD-10) did not adequately support the current management of pain. Therefore, we aimed to review the new 11th revision (ICD-11) in order to analyze its usefulness for the management, coding, research and education of chronic pain from a Latin American perspective. The Latin American Federation of Associations for the Study of Pain convened a meeting of pain experts in Lima, Peru.

Background & Aims: It has been reported that specific killer-cell immunoglobulin-like receptors (KIRs) and HLA genotype combinations, such as KIR2DS4/HLA-C1 with presence of KIRDL2 or KIRDL3, homozygous KIRDL3/HLA-C1 and KIR3DL1/≥2HLA-Bw4, are strongly associated with the lack of active infection and seroconversion after exposition to hepatitis C virus (HCV).

Objective: To determine whether these KIR-HLA combinations are relevant factors involved in that phenotype.

Patients And Methods: In this retrospective case-control study, genotype data from a genome-wide association study previously performed on low susceptibility to HCV-infection carried out on 27 high-risk HCV-seronegative (HRSN) individuals and 743 chronically infected (CI) subjects were used.

Background: About 25% of patients with acute hepatitis C virus (HCV) infection show spontaneous clearance within the first six months of infection but may remain at risk of inflammaging, aging, and liver and non-liver disease complications. This study evaluated the differences in the plasma levels of immune checkpoints (ICs) and senescence-associated secretory phenotype (SASP) biomarkers between patients who had spontaneously eliminated HCV infection (SC group) and individuals without evidence of HCV infection (C group).

Methods: We performed a multicenter retrospective study of 56 individuals: 32 in the SC and 24 in the C groups.

Managed honey bees have experienced high rates of colony loss recently, with pesticide exposure as a major cause. While pesticides can be lethal at high doses, lower doses can produce sublethal effects, which may substantially weaken colonies. Impaired learning performance is a behavioral sublethal effect, and is often present in bees exposed to insecticides.
