Background: Lead is found in small but appreciable quantities in air, soil, drinking water, and food. Exposure to such amounts of lead does not lead to acute lead toxicity but produces subtle effects particularly in children. The aim of this study was to investigate the effects of blood lead level on biochemical and hematological parameters in children with neurological diseases in Western Maharashtra, India, and to estimate the blood lead level by liver and kidney function tests and hematological parameters in children with neurological disorders admitted to the pediatric ward and compare them with healthy controls.
Methods: In this study, 30 children with various neurological disorders admitted to the pediatric ward of Smt. Kashibai Navale Medical College and General Hospital, Pune, Maharashtra, India, were compared with 30 age- and sex-matched healthy controls. Four milliliters of venous blood was collected for estimation of blood lead level, and biochemical and hematological parameters were determined using standard methods.
Results: Blood lead level was significantly increased in the study group (p<0.01, 65.38%) compared to that in the control group. When different neurological conditions were grouped into three groups according to blood lead levels, there was a significant difference between the groups. All other biochemical and hematological parameters were not significantly altered in the study group as compared to the control group.
Conclusions: Neurologically challenged children are more vulnerable to lead intoxication. It is imperative for the parents to take extra care of their children's food habits and limit hand-to-mouth activities to prevent lead intoxication.

Metabolic syndrome during menopause can lead to diabetes, cardiovascular problems, and increased mortality rates. Hormone replacement therapy is recommended to manage climacteric complications, but it has serious adverse effects. This study, therefore, investigated the potential of supplementing some minerals, vitamins, and natural products like boric acid, magnesium, vitamin D3, and extra virgin olive oil on metabolic status of menopausal ovariectomized rats.

Hemodynamic stabilization is crucial in managing acute cardiac events, where compromised blood flow can lead to severe complications and increased mortality. Conditions like decompensated heart failure (HF) and cardiogenic shock require rapid and effective hemodynamic support. Current mechanical assistive devices, such as intra-aortic balloon pumps (IABP) and extracorporeal membrane oxygenation (ECMO), offer temporary stabilization but are limited to short-term use due to risks associated with prolonged blood contact.

Peripapillary pachychoroid syndrome (PPS) is a recently described condition, classified within the pachychoroid disease spectrum characterized by focal or diffuse thickening of the choroid due to dilation of choroidal vessels in the Haller's layer (pachyvessels), thinning of the choriocapillaris and the Sattler's layer, and accompanied by increased choroidal permeability and damage to the retinal pigment epithelium. Unlike other pachychoroid diseases that involve changes in the central retina, PPS presents with choroidal thickening and intra- or subretinal fluid located nasally in the macular region, near the optic disc. This review aims to summarize and analyze current data on the clinical features, pathogenesis, and treatment options for PPS found in the literature.

Metabolic syndrome (MetS) is an indicator and diverse endocrine syndrome that combines different metabolic defects with clinical, physiological, biochemical, and metabolic factors. Obesity, visceral adiposity and abdominal obesity, dyslipidemia, insulin resistance (IR), elevated blood pressure, endothelial dysfunction, and acute or chronic inflammation are the risk factors associated with MetS. Abdominal obesity, a hallmark of MetS, highlights dysfunctional fat tissue and increased risk for cardiovascular disease and diabetes.

Vertebrates differ over 100,000-fold in responses to pro-inflammatory agonists such as bacterial lipopolysaccharide (LPS), complicating use of animal models to study human sepsis or inflammatory disorders. We compared transcriptomes of resting and LPS-exposed blood from six LPS-sensitive species (rabbit, pig, sheep, cow, chimpanzee, human) and four LPS-resilient species (mice, rats, baboon, rhesus), as well as plasma proteomes and lipidomes. Unexpectedly, at baseline, sensitive species already had enhanced expression of LPS-responsive genes relative to resilient species.
