Homozygous DNAJB4 deletion revealing myopathy with acute respiratory failure.

Homozygous mutations in the DNAJB4 (NM_007034) gene impair HSP40 function, leading to early respiratory failure due to diaphragm involvement and rigid-spine-like characteristics. We describe the case of a 23-year-old male patient who was admitted for acute respiratory failure and motor deficit of the distal upper limbs. Creatine kinase values were elevated (10x upper normal limit), while the pulmonary function tests showed restrictive respiratory syndrome (forced vital capacity at 20% of theoretical values).

Autosomal dominant distal myopathy due to p.Ser85Cys mutation in the MATR3 gene: Novel case series and literature review.

Introduction: Matrin-3 autosomal dominant myopathy, most commonly caused by a Ser85Cys (S85C) missense mutation, is a rare distal myopathy, presenting a heterogeneous phenotype.

Methods: We report the clinical, physiological, radiological, and histological features of the first Portuguese patients diagnosed with p.Ser85Cys MATR3-related myopathy using a specific gene panel dedicated to "distal myopathies".

Oxytocin Exhibits Neuroprotective Effects on Hippocampal Cultures under Severe Oxygen-Glucose Deprivation Conditions.

Perinatal asphyxia (PA) and hypoxic-ischemic encephalopathy can result in severe, long-lasting neurological deficits. In vitro models, such as oxygen-glucose deprivation (OGD), are used experimentally to investigate neuronal response to metabolic stress. However, multiple variables can affect the severity level of OGD/PA and may confound any measured treatment effect.

Comparative Analysis of Hematological and Immunological Parameters in Patients with Primary Sjögren's Syndrome and Peripheral Neuropathy.

Background: Primary Sjögren syndrome (pSS) is a multisystem disorder of autoimmune etiology, frequently involving peripheral nerves. Early detection of peripheral neuropathy (PN) manifestations might improve prognosis and disease control. The purpose of the study was to evaluate the predictive potential of hematological and immunological parameters associated with PN development in pSS patients.

Melatonin-Microbiome Two-Sided Interaction in Dysbiosis-Associated Conditions.

Melatonin is a pineal indolamine, allegedly known as a circadian rhythm regulator, and an antioxidative and immunomodulatory molecule. In both experimental and clinical trials, melatonin has been shown to have positive effects in various pathologies, as a modulator of important biochemical pathways including inflammation, oxidative stress, cell injury, apoptosis, and energy metabolism. The gut represents one of melatonin's most abundant extra pineal sources, with a 400-times-higher concentration than the pineal gland.
