The finger-ring test as an indicator of muscle mass estimated by dual-energy X-ray absorptiometry in an adult community-dwelling population.

Introduction: The finger-ring test (FRT) offers a simple method to screen older adults at increased risk of sarcopenia.

Objective: To investigate the association between the FRT and lean soft tissue mass estimated by dual-energy X-ray absorptiometry (DXA), and to further elucidate the FRT as an indicator of muscle mass, while accounting for potential confounders, in a community-dwelling population.

Materials And Methods: Within this cross-sectional study 430 community-dwelling individuals aged 18 to 79 (286 women (66.

Predictive factors for dose reduction and discontinuation of nintedanib in fibrotic interstitial lung diseases: Real life data.

Nintedanib, an intracellular inhibitor targeting multiple tyrosine kinases, has emerged as a standard treatment for various fibrotic lung diseases. Despite its efficacy, side effects such as nausea, diarrhea, and hepatotoxicity often lead to dose reduction or discontinuation. In this retrospective analysis at an university hospital's interstitial lung disease clinic, we aimed to identify baseline characteristics associated with dose adjustment or treatment discontinuation.

Emerging therapeutic strategies in hypoxic-ischemic encephalopathy: a focus on cognitive outcomes.

Perinatal hypoxia-ischemia represents a significant risk to CNS development, leading to high mortality rates, diverse damages, and persistent neurological deficits. Despite advances in neonatal medicine in recent decades, the incidence of HIE remains substantial. Motor deficits can manifest early, while cognitive impairments may be diagnosed later, emphasizing the need for extended follow-up.

Neurodevelopment and Dietary Intake in Toddlers-A Cross-Sectional Study from the Healthy Children 2021 Project.

Little is known about the potential associations between neurodevelopment, dietary diversity and food processing in the toddler period. This study aimed to estimate the association between these dietary quality dimensions and neurodevelopment in toddlers. Data for this cross-sectional analysis came from the Healthy Children 2021 project and included 212 toddlers (51.

Depressive-like behavior and impaired synaptic plasticity in the prefrontal cortex as later consequences of prenatal hypoxic-ischemic insult in rats.

Perinatal hypoxia-ischemia (HI) is a leading cause of morbidity and mortality among newborns. Infants with HI encephalopathy may experience lasting consequences, such as depression, in adulthood. In this study, we examined depressive-like behavior, neuronal population, and markers of monoaminergic and synaptic plasticity in the prefrontal cortex (PFC) of adolescent rats subjected to a prenatal HI model.

Effects of prenatal hypoxia-ischemia on male rat periaqueductal gray matter: Hyperalgesia, astrogliosis and nitrergic system impairment.

Prenatal hypoxic-ischemic insult (HI) may lead to a variety of neurological consequences that may persist throughout adulthood. In the most severe cases, HI is known to increase pain sensitivity which profoundly impacts quality of life. Periaqueductal gray matter (PAG) is a relevant region of the descending pain pathway and its function may be modulated by a complex network that includes nitrergic neurons and glial response, among other factors.

Caffeine and Its Neuroprotective Role in Ischemic Events: A Mechanism Dependent on Adenosine Receptors.

Ischemia is characterized by a transient, insufficient, or permanent interruption of blood flow to a tissue, which leads to an inadequate glucose and oxygen supply. The nervous tissue is highly active, and it closely depends on glucose and oxygen to satisfy its metabolic demand. Therefore, ischemic conditions promote cell death and lead to a secondary wave of cell damage that progressively spreads to the neighborhood areas, called penumbra.

GABA function may be related to the impairment of learning and memory caused by systemic prenatal hypoxia-ischemia.

Intrauterine adverse conditions may be responsible for long-lasting damages which impact health even during adult phase. Hypoxic-ischemic (HI) events are a relevant cause of newborn mortality and the principal factor leading to permanent brain lesions. Using a model in which the ovarian and uterine flux of a pregnant rat is obstructed for 45 min we have described oligodendrocyte death, astrogliosis and neuronal loss.

Prenatal Systemic Hypoxia-Ischemia and Oligodendroglia Loss in Cerebellum.

Hypoxic-ischemic (HI) injury is an important cause of death and disabilities. Despite all improvements in neonatal care, the number of children who suffer some kind of injury during birth has remained stable in the last decade. A great number of studies have shown alterations in neural cells and many animal models have been proposed in the last 5 decades.

Genistein-supplemented diet decreases malaria liver infection in mice and constitutes a potential prophylactic strategy.

In tropical regions millions of people still live at risk of malaria infection. Indeed the emergence of resistance to chloroquine and other drugs in use in these areas reinforces the need to implement alternative prophylactic strategies. Genistein is a naturally occurring compound that is widely used as a food supplement and is thought to be effective in countering several pathologies.

Heme oxygenase-1 and carbon monoxide suppress the pathogenesis of experimental cerebral malaria.

Cerebral malaria claims more than 1 million lives per year. We report that heme oxygenase-1 (HO-1, encoded by Hmox1) prevents the development of experimental cerebral malaria (ECM). BALB/c mice infected with Plasmodium berghei ANKA upregulated HO-1 expression and activity and did not develop ECM.

Bone marrow chimeric mice reveal a dual role for CD36 in Plasmodium berghei ANKA infection.

Background: Adhesion of Plasmodium-infected red blood cells (iRBC) to different host cells, ranging from endothelial to red blood cells, is associated to malaria pathology. In vitro studies have shown the relevance of CD36 for adhesion phenotypes of Plasmodium falciparum iRBC such as sequestration, platelet mediated clumping and non-opsonic uptake of iRBC. Different adhesion phenotypes involve different host cells and are associated with different pathological outcomes of disease.

Infection by and protective immune responses against Plasmodium berghei ANKA are not affected in macrophage scavenger receptors A deficient mice.

Background: Scavenger receptors (SRs) recognize endogenous molecules modified by pathological processes as well as components of diverse microorganisms. Mice deficient for both SR-AI and II are more susceptible to infections by a variety of bacterial and viral pathogens.

Results: Here we show that SR-A deficient mice and wild type mice are equally susceptible to malaria infection both during liver and blood stages.

Antimalarial drugs - host targets (re)visited.

Every year, forty percent of the world population is at risk of contracting malaria. Hopes for the erradication of this disease during the 20th century were dashed by the ability of Plasmodium falciparum, its most deadly causative agent, to develop resistance to available drugs. Efforts to produce an effective vaccine have so far been unsuccessful, enhancing the need to develop novel antimalarial drugs.

Murine malaria parasite sequestration: CD36 is the major receptor, but cerebral pathology is unlinked to sequestration.

Sequestration of malaria-parasite-infected erythrocytes in the microvasculature of organs is thought to be a significant cause of pathology. Cerebral malaria (CM) is a major complication of Plasmodium falciparum infections, and PfEMP1-mediated sequestration of infected red blood cells has been considered to be the major feature leading to CM-related pathology. We report a system for the real-time in vivo imaging of sequestration using transgenic luciferase-expressing parasites of the rodent malaria parasite Plasmodium berghei.
