A 40-year-old male farmer from rural West Bengal, India, presented with fever, headaches, seizure, eschar, and palsy of left cranial nerves VII, VIII, IX, and X as a rare clinical manifestation of scrub typhus. Positive IgM enzyme-linked immunosorbent assay tests in serum and cerebrospinal fluid confirmed the diagnosis, with brain magnetic resonance imaging showing meningoencephalitis findings. Treatment with steroids and doxycycline led to neurological improvement.

Neurometabolic substrate transport across brain barriers in diabetes mellitus: Implications for cognitive function and neurovascular health.

Neurosci Lett

November 2024

Department of Neurology, University Hospital "12 de Octubre", Madrid, Spain; Instituto de Investigación Sanitaria Hospital 12 de Octubre (imas12), Madrid, Spain; Centro de Investigación Biomédica en Red Sobre Enfermedades Neurodegenerativas (CIBERNED), Madrid, Spain; Department of Medicine, Complutense University, Madrid, Spain. Electronic address:

Article Synopsis
  • Neurometabolic homeostasis in the brain relies on the effective transport of glucose and nutrients across brain barriers, which gets disrupted in type 2 diabetes mellitus (T2DM) due to high blood sugar levels.
  • T2DM causes reduced glucose transporter expression and impaired neurovascular coupling, leading to cognitive decline and neurovascular dysfunction.
  • Insulin plays a crucial role in the hippocampus by improving neuro-glial interactions and facilitating glucose uptake in astrocytes to meet the energy needs of neurons, highlighting the need for strategies to correct glucose transport issues in T2DM.

Alzheimer's disease (AD), the most prevalent form of dementia, is expected to rise dramatically in incidence due to the global population aging. Traditional diagnostic approaches, such as cerebrospinal fluid analysis and positron emission tomography, are expensive and invasive, limiting their routine clinical use. Recent advances in blood-based biomarkers, including amyloid-beta, phosphorylated tau, and neurofilament light, offer promising non-invasive alternatives for early AD detection and disease monitoring.

Article Synopsis
  • Respiratory syncytial virus-associated acute respiratory infection (RSV-ARI) is increasingly affecting adults, leading to serious health issues, as shown in a study of 275 hospitalized patients.
  • In this study, 11.2% of patients experienced poor outcomes, with certain factors increasing their risk, such as cognitive impairment, use of anticoagulants, and low oxygen saturation ratios upon hospital admission.
  • Interestingly, receiving the flu vaccine in the current season was found to reduce the risk of poor outcomes, underscoring the importance of early risk assessment for RSV-ARI in the emergency department.

  • Cardiogenic shock (AMI-CS) is a severe condition following acute myocardial infarction, showing high rates of morbidity and mortality, especially highlighting ongoing gender disparities in treatment.* -
  • A study analyzing data from 151,560 AMI-CS patients found that women were significantly less likely to receive mechanical circulatory support (MCS) and had higher in-hospital mortality rates than men, despite no major differences in bleeding or other complications.* -
  • Racial disparities were noted, with female patients from all racial backgrounds receiving less MCS than their male counterparts, while Black and Hispanic patients had lower MCS utilization compared to White patients, emphasizing the complexities of gender, race, and healthcare access.*

Servicio de Cardiología, Complejo Hospitalario Universitario de A Coruña (CHUAC), Instituto de Investigación Biomédica de A Coruña (INIBIC), A Coruña, Spain; Centro de Investigación Biomédica en Red de Enfermedades Cardiovasculares (CIBERCV), Spain; Facultad de Ciencias de la Salud, Universidad de A Coruña, A Coruña, Spain.

Article Synopsis
  • * A total of 245 patients were analyzed, with 54.3% using mechanical LV unloading techniques, primarily the intra-aortic balloon pump, showing an improved 1-year survival rate of 74.4% compared to 59.8% in those without LV unloading.
  • * The findings suggest that preoperative LV unloading is linked to better survival rates after a year post-transplant, with no notable differences in other postoperative complications between groups.

The therapeutic use of clonal neural stem cells in experimental Parkinson´s disease.

Stem Cell Res Ther

October 2024

Unit of Molecular Neuropathology, Physiological and pathological processes Program, Centro de Biología Molecular Severo Ochoa UAM-CSIC, Calle Nicolás Cabrera, 1, Madrid, 28049, Spain.

Background: Parkinson´s disease (PD), the second most common neurodegenerative disease in the world, is characterized by the death or impairment of dopaminergic neurons (DAn) in the substantia nigra pars compacta and dopamine depletion in the striatum. Currently, there is no cure for PD, and treatments only help to reduce the symptoms of the disease, and do not repair or replace the DAn damaged or lost in PD. Cell replacement therapy (CRT) seeks to relieve both pathological and symptomatic PD manifestations and has been shown to have beneficial effects in experimental PD models as well as in PD patients, but an apt cell line to be used in the treatment of PD has yet to be established.

  • The study assessed outcomes, resource use, and costs related to Chronic Obstructive Pulmonary Disease (COPD) by analyzing a cohort of patients who visited the emergency department in 2018.
  • In a sample of 2,384 COPD patients, the study found high mortality rates—23.4% within one year—and significant readmission rates, with costs totaling approximately €14.6 million.
  • The findings highlight the need for specialized programs to improve care for COPD patients due to their high mortality, readmission rates, and substantial economic burden on the healthcare system.

Objective: Acute intermittent porphyria (AIP) is a rare metabolic disorder caused by haploinsufficiency of hepatic porphobilinogen deaminase (PBGD), the third enzyme of the heme biosynthesis. Individuals with AIP experience neurovisceral attacks closely associated with hepatic overproduction of potentially neurotoxic heme precursors.

Design: We replicated AIP in non-human primates (NHPs) through selective knockdown of the hepatic gene and evaluated the safety and therapeutic efficacy of human PBGD (hPBGD) mRNA rescue.

Article Synopsis
  • Scrub typhus is a disease caused by mites and is common in the Asia Pacific, leading to serious neurological problems like meningoencephalitis and, in rare cases, CVST.
  • A unique case involved an 18-year-old pregnant woman in India who, after experiencing symptoms like fever and headaches, was found to have CVST stemming from scrub typhus meningoencephalitis; treatment involved azithromycin and later anticoagulation therapy.
  • The report emphasizes the need to consider CVST in pregnant women with severe scrub typhus symptoms even if antibiotics are being used, as early treatment is crucial for better outcomes.

  • The MOSCA-FRAIL trial examined the effects of invasive versus conservative treatment strategies in frail patients aged 70 and older with non-ST-segment elevation myocardial infarction (NSTEMI).
  • The study included 167 participants and focused on various geriatric conditions, finding that invasive management had a notable survival benefit primarily for those with lower frailty levels (CFS=4).
  • Results suggested that frailty, as indicated by the Clinical Frailty Scale (CFS), is an important factor in determining the risks and benefits of treatment, with a CFS score greater than 4 potentially signaling a need for more cautious decision-making.

Article Synopsis
  • - Dendritic cells (DCs) are key players in the immune system that help activate T cells essential for fighting viral infections, and the nuclear envelope protein lamin A/C is linked to T cell immunity.
  • - Mice lacking lamin A/C in specific immune cells show weakened responses in activating important T cell types, resulting in less effective clearance of viral infections like Vaccinia virus (VACV).
  • - The study suggests that the absence of lamin A/C affects how DCs interact with T cells and influences gene expression, which ultimately impacts the immune system's ability to respond to viruses.

Placing a nasogastric tube (NGT) is a frequent nursing technique in intensive care units. The gold standard for its correct positioning is the chest X-ray due to its high sensitivity, but it represents a radiation source for critically ill patients. Our study aims to analyze whether the ultrasound performed by an intensive care nurse is a valid method to verify the NGT's correct positioning and to evaluate the degree of interobserver agreement between this nurse and an intensive care physician in the NGT visualization using ultrasound.
