Differences in association between hypoalbuminaemia and mortality among younger versus older patients on haemodialysis.

Background: Ageing often affects biomarker production. Yet, clinical/optimal thresholds to guide clinical decisions do not consider this. Serum albumin decreases with age, but hypoalbuminaemia is defined as serum albumin <4.

Statistical methods to adjust for the effects on intervention compliance in randomized clinical trials where precision treatment rules are being developed.

Background: Heterogeneity of treatment effects (HTEs) can occur because of either differential treatment compliance or differential treatment effectiveness. This distinction is important, as it has action implications, but it is unclear how to distinguish these two possibilities statistically in precision treatment analysis given that compliance is not observed until after randomization. We review available statistical methods and illustrate a recommended method in secondary analysis in a trial focused on HTE.

Impact of obesity on iron metabolism and the effect of intravenous iron supplementation in obese patients with absolute iron deficiency.

Obesity and iron deficiency (ID) are widespread health issues, with subclinical inflammation in obesity potentially contributing to ID through unclear mechanisms. The aim of the present work was to elucidate how obesity-associated inflammation disturb iron metabolism and to investigate the effect of intravenous (IV) iron supplementation on absolute iron deficient pre-obese (BMI 25.0-29.

Influenza vaccine outcomes: a meta-analysis revealing morbidity benefits amid low infection prevention.

Background: The morbidity and mortality associated with influenza viruses are a significant public health challenge. Annual vaccination against circulating influenza strains reduces hospitalisations and increases survival rates but requires a yearly redesign of vaccines against prevalent subtypes. The complex genetics of influenza viruses with high antigenic drift create an ongoing challenge in vaccine development to address dynamic influenza epidemiology.

Clinical Benefit of a Conservative Treatment for High-Risk Human Papillomavirus Lesions in Patients with HIV.

Participants identified as: Native American/Alaskan native, 1.90%; Asian, .

MicroRNA-199a-5p may be a diagnostic biomarker of primary ITP.

There is no diagnostic test for primary immune thrombocytopenia (ITP). Certain microRNAs have shown to have diagnostic potential in ITP. We validated 12 microRNAs identified from two previous studies to find a diagnostic biomarker.

Challenges for implementing culturally competent obstetric services in an Indigenous context in Mexico.

Obstetric healthcare for Indigenous women remains a severe problem in low-income countries with great cultural diversity and a colonial past. The work of health professionals to prevent complications leading to maternal deaths is paramount, yet in these contexts, they face significant challenges in implementing culturally competent services. This paper aims to present findings from an ethnographic study that attempted to document the experience of health professionals providing obstetric services in order to show the complex sociocultural contexts in which they perform their work.

Association between demographic, clinical characteristics and severe complications by SARS-CoV-2 infection in a community-based healthcare network in Chile.

Background: Most of the evidence on risk factors for COVID-19 complications comes from North America or Europe with very little research from Latin-America. We aimed to evaluate the association between sociodemographic, clinical factors and the risk of COVID-19 complications among adults in Chile, the fifth Latin-American country with more COVID-19 reported cases since de beginning of the Pandemic.

Methods: A retrospective population-based cohort study using data from electronic health records from a large Primary Care Network, linked to national hospital, immunization, Covid-19 PCR surveillance, mortality and birth records.

Effects of early, late and self-selected time-restricted eating on visceral adipose tissue and cardiometabolic health in participants with overweight or obesity: a randomized controlled trial.

The optimal eating window for time-restricted eating (TRE) remains unclear, particularly its impact on visceral adipose tissue (VAT), which is associated with cardiometabolic morbidity and mortality. We investigated the effects of three TRE schedules (8 h windows in the early day, late day and participant-chosen times) combined with usual care (UC, based on education about the Mediterranean diet) versus UC alone over 12 weeks in adults with overweight or obesity. The primary outcome was VAT changes measured by magnetic resonance imaging.

Primary care utilisation in different patients' profiles with cardiovascular risk factors.

Background: This study aimed to identify profiles of patients with cardiovascular disease (CVD) risk factors, based on their sociodemographic and clinical characteristics, and to analyse how their complexity is related to their frequency of visits in Primary Care.

Methods: Observational longitudinal study conducted in the Spanish CArdiovascular Risk factors for HEalth Services research (CARhES) cohort. Individuals older than 15 with hypertension, type 2 diabetes mellitus (DM) and/or dyslipidaemia in 2017 were selected and followed until 2021.

Interaction between microRNA and KRAS in Glioblastoma.

Glioblastoma (GBM) characterized byits rapid progression and challenging prognosis, often featuring mutations in the Kirsten rat sarcoma virus (KRAS) gene, which is crucial for numerous cellular signaling mechanisms. Emerging research underscores a significant interaction between KRAS and microRNAs (miRNAs) in these cancers, with miRNAs playing key roles as both regulators and mediators within the KRAS signaling framework. The concept of oncogene-induced senescence (OIS) is explored as a protective mechanism against tumor development, examining how K-RAS signaling is meticulously adjusted to bypass senescence, thereby enhancing cell growth and survival.
