Relevance of the Glutathione System in Temporal Lobe Epilepsy: Evidence in Human and Experimental Models

Oxidative stress, which is a state of imbalance in the production of reactive oxygen species and nitrogen, is induced by a wide variety of factors. This biochemical state is associated with diseases that are systemic as well as diseases that affect the central nervous system. Epilepsy is a chronic neurological disorder, and temporal lobe epilepsy represents an estimated 40% of all epilepsy cases. Currently, evidence from human and experimental models supports the involvement of oxidative stress during seizures and in the epileptogenesis process. Hence, the aim of this review was to provide information that facilitates the processing of this evidence and investigate the therapeutic impact of the biochemical status for this specific pathology

Análisis de Enfermedades Musculoesqueléticas y su Relación con Hábitos de Vida Saludable en la Policía Metropolitana Santiago de Cali

Identificar qué relación hay entre las enfermedades musculoesqueléticas y los hábitos de vida saludable, de los miembros de la Policía Metropolitana de Santiago de Cali.Los Trastornos musculoesqueléticos (TME) relacionados con el trabajo afectan principalmente a la espalda, el cuello, los hombros y las extremidades tanto superiores como inferiores y se incluye en ellos cualquier daño o trastorno de las articulaciones u otros tejidos. Los problemas de salud varían desde molestias y dolores leves hasta enfermedades más graves que requieren baja por enfermedad o tratamiento médico. En los casos crónicos estos trastornos pueden provocar una discapacidad e impedir que la persona afectada siga trabajando. La mayoría de los TME relacionados con el trabajo se desarrollan con el tiempo. Por lo general estos trastornos no tienen una sola causa y, a menudo, son el resultado de combinar varios factores de riesgo, como hábitos de vida, factores físicos, biomecánicos y psicosociales. Los hábitos de vida saludable según Dellert S. Elliot (1993) son los comportamientos que implican un riesgo para la salud o la protegen. Estos comportamientos son rutinarios del ser humano y tienen efectos en la salud generando bienestar físico, mental y social

Development and sedative effect of a new formulation of midazolam in chocolate bars

The aim of this work was to assess the stability and sedative effect of midazolam in chocolate bars. The stability of 5 g chocolate bars containing 6 mg midazolam hydrochloride was evaluated at room temperature (25 ± 2 °C), at 4 and 40 °C, by HPLC. Drug plasma levels were measured and the sedative effect was confirmed in six healthy volunteers according to the Ramsay’s scale. Data regarding chocolate bar administration were compared to those from the apple juice solution. Pharmacokinetic data were processed using the WinNonLin 5.2 software. Midazolam in chocolate bars remained stable for 14 days at room temperature and exposed to light; for 90 days at 4 and 40 °C protected from light, and showed a longer shelf life, better flavour and appearance, inducing the same sedative effect as the apple juice preparation. Raspberry flavour masked midazolam unpleasing taste most favourably.Colegio de Farmacéuticos de la Provincia de Buenos Aire

Modulation of Antioxidant Enzymatic Activities by Certain Antiepileptic Drugs (Valproic Acid, Oxcarbazepine, and Topiramate): Evidence in Humans and Experimental Models

It is estimated that at least 100 million people worldwide will suffer from epilepsy at some point in their lives. This neurological disorder induces brain death due to the excessive liberation of glutamate, which activates the postsynaptic N-methyl-D-aspartic acid (NMDA) receptors, which in turn cause the reuptake of intracellular calcium (excitotoxicity). This excitotoxicity elicits a series of events leading to nitric oxide synthase (NOS) activation and the generation of reactive oxygen species (ROS). Several studies in experimental models and in humans have demonstrated that certain antiepileptic drugs (AEDs) exhibit antioxidant effects by modulating the activity of various enzymes associated with this type of stress. Considering the above-mentioned data, we aimed to compile evidence elucidating how AEDs such as valproic acid (VPA), oxcarbazepine (OXC), and topiramate (TPM) modulate oxidative stress

Impact of treatment and clinical characteristics on the survival of children with medulloblastoma in Mexico

IntroductionData on medulloblastoma outcomes and experiences in low- and middle-income countries, especially in Latin America, is limited. This study examines challenges in Mexico’s healthcare system, focusing on assessing outcomes for children with medulloblastoma in a tertiary care setting.MethodsA retrospective analysis was conducted, involving 284 patients treated at 21 pediatric oncology centers in Mexico.ResultsHigh-risk patients exhibited markedly lower event-free survival than standard-risk patients (43.5% vs. 78.3%, p<0.001). Influential factors on survival included anaplastic subtype (HR 2.4, p=0.003), metastatic disease (HR 1.9, p=0.001); residual tumor >1.5cm², and lower radiotherapy doses significantly impacted event-free survival (EFS) and overall survival (OS). Platinum-based chemotherapy showed better results compared to the ICE protocol in terms of OS and EFS, which was associated with higher toxicity. Patients under 3 years old displayed notably lower OS and EFS compared to older children (36.1% vs. 55.9%, p=0.01)

Sodium restriction in patients with chronic heart failure and reduced ejection fraction: A randomized controlled trial

Background: Sodium restriction is recommended for patients with heart failure (HF) despite the lack of solid clinical evidence from randomized controlled trials. Whether or not sodium restrictions provide beneficial cardiac effects is not known. Methods: The present study is a randomized, double-blind, controlled trial of stable HF patients with ejection fraction ≤ 40%. Patients were allocated to sodium restriction (2 g of sodium/day) vs. control (3 g of sodium/day). The primary outcome was change in N-terminal pro-B-type natriuretic peptide (NT-proBNP) at 20 weeks. Secondary outcomes included quality of life and adverse safety events (HF readmission, blood pressure or electrolyte abnormalities). Results: Seventy patients were enrolled. Median baseline sodium consumption was 3268 (2225–4537) mg/day. Adherence to the intervention based on 24-hour urinary sodium was 32%. NT-proBNP and quality of life did not significantly change between groups (p > 0.05 for both). Adverse safety events were not significantly different between the arms (p > 0.6 for all). In the per protocol analysis, patients who achieved a sodium intake < 2500 mg/day at the  intervention conclusion showed improvements in NT-proBNP levels (between-group difference: –55%, 95% confidence interval –27 to –73%; p = 0.002) and quality of life (between-group difference –11 ± 5 points; p = 0.04). Blood pressure decreased in patients with lower sodium intake (between-group difference –9 ± 5 mmHg; p = 0.05) without significant differences in symptomatic hypotension or other safety events (p > 0.3 for all). Conclusions: Adherence assessed by 24-hour natriuresis and by the nutritionist was poor. The group allocated to sodium restriction did not show improvement in NT-proBNP. However, patients who achieved a sodium intake < 2500 mg/day appeared to have improvements in NT-proBNP and quality of life without any adverse safety signals.
