The scope of this study was to identify the profile of fragility and associated factors among the elderly registered in a Family Health Unit. It involved an observational, exploratory, household -based and cross-sectional study conducted with 139 elderly individuals. The data were collected using a structured questionnaire requesting the following information: personal history, family and self-reported diseases, socio-demographic information, level of physical activity, behavior variables, number of falls in the last year, depressive symptoms, unintentional weight loss and fatigue. Anthropometric measurements (weight and height) were also taken and the body mass index (BMI) was calculated. Descriptive analyses and Pearson's chi-square test or Fisher's exact test were performed, with a significance level of p < 0.05. SPSS software version 21.0 was used for statistical analysis. The prevalence of fragility among the elderly was: frail (16.9%), pre-frail (61.8%) and non-frail (21.3%), respectively. The fragility profile was associated with: age (p < 0.001), BMI (p = 0.018), family situation (p = 0.014), level of physical activity (p < 0.001) and falls (p = 0.043). In this study, a high prevalence was observed of pre-frail and frail elderly individuals and identified factors associated with this syndrome.

Babesiosis in sickle cell disease (SCD) is marked by severe anemia but the underlying red blood cell (RBC) rheological parameters remain largely undefined. Here, we describe altered RBC deformability from both primary (host RBC sickle hemoglobin mediated) and secondary changes (Babesia parasite infection mediated) to the RBC membrane using wild type AA, sickle trait AS and sickle SS RBCs. Our ektacytometry (LORRCA) analysis demonstrates that the changes in the host RBC bio-mechanical properties, pre- and post- Babesia infection, reside on a spectrum of severity, with wild type infected AA cells, despite showing a significant reduction of deformability under both shear and osmolarity gradients, exhibiting only a mild phenotype; compared to infected AS RBCs which show median changes in deformability and infected SS RBCs which exhibit the most dramatic impact of infection on cellular rheology, including an increase in Point of Sickling values.

Diabetes mellitus is a widespread metabolic disorder linked to numerous systemic complications, including adverse effects on skeletal health, such as increased bone fragility and fracture risk. Emerging evidence suggests that high glucose may disrupt the extracellular matrix (ECM) of bone, potentially altering its composition and organization. Collagen, the primary organic component of the ECM, is critical for maintaining structural integrity and biomechanical properties.

Background: Epidermolysis bullosa (EB) is a group of rare, severe, genetic disorders characterised by persistent skin fragility and open wounds. EB manifests as cutaneous and mucosal blistering, erosions and impaired wound healing.
Objectives: To determine the long-term efficacy, tolerability and safety of Oleogel-S10 (birch bark extract) in dystrophic (DEB) and junctional (JEB) EB in the 24-months open-label phase (OLP) of the EASE study.

Type 1 diabetes (T1D) represents a significant health burden worldwide, with associated complications including bone fragility. Current clinical methods and biomarkers for assessing bone health and predicting fracture risk in T1D are limited and lack accuracy. MicroRNAs (miRNAs) have emerged as potential biomarkers for predicting T1D-induced bone loss, although comprehensive profiling studies are lacking.
