Association of HLA Class I Repertoire Score with Severity of Human Cytomegalovirus Infection in Transplant Patients.

Human Cytomegalovirus (HCMV) is a common herpesvirus that typically causes asymptomatic infection but can lead to severe complications in transplant patients due to reactivation. The Human Leukocyte Antigen (HLA) plays a crucial role in antigen presentation and T cell activation, essential for an effective immune response. Understanding HLA-pathogen interactions can help predict susceptibility or resistance to infection.

Directional deep brain stimulation in the management of Parkinson's disease: efficacy and constraints-an analytical appraisal.

Deep brain stimulation (DBS) is a widely employed treatment for Parkinson's disease. However, conventional DBS utilizing ring-shaped leads can often result in undesirable side effects by stimulating nearby brain structures, thus limiting its effectiveness. To address this issue, a novel DBS electrode was developed to allow for directional stimulation, avoiding neighboring structures.

Influences of Sex and Age on the Hematological Profile of the Jundiá (Silver Catfish) Rhamdia quelen.

In this study, sex and age influenced the hematological profiles of Jundiá (Silver Catfish) Rhamdia quelen. Females showed lower levels of hemoglobin, young fish increased lymphocyte counts, and older fish increased hematocrit values. These results indicate that, depending on age and sex, the fish have disparate hematological profiles.

[Cardiac tamponade: a rare complication of central venous catheter - a clinical case report].

The extensive use of central venous catheters (CVC) in a hospital environment leads to increased iatrogenic complications, as more catheters are used enclosed and its maintenance is prolonged. Several complications are known to be related to central venous catheter, of which the uncommon cardiac tamponade (CT), hardly recognized and associated with high mortality. We present a clinical case, with favorable outcome, of a patient who developed a CT 17 days after CVC placement, and try to reflect on the measures that can be taken to reduce its incidence, as well as the therapeutic approaches to practice in the presence of a suspected CT.

Water quality assessment of the Tubarão River through chemical analysis and biomarkers in the Neotropical fish Geophagus brasiliensis.

The Tubarão River rises in Santa Catarina, Brazil, and has been historically affected by coal mining activities around its springhead. To evaluate its water conditions, an investigation regarding a possible decontamination gradient associated with the increased river flow toward the estuary, as well as the influence of seasonality over this gradient was performed through a series of biomarkers (vitellogenin, comet assay, lipid peroxidation, protein carbonylation, gluthatione, gluthatione S-transferase, acetylcholinesterase, light microscopy in liver, and scanning electron microscopy in gills) and chemical analysis (polycyclic aromatic hydrocarbons (PAHs) in bile and metal analysis in sediment) in the cichlid Geophagus brasiliensis. Two collections (summer and winter) were made in four distinct sites along the river, while sediments were sampled between those seasons.

Brain magnetic resonance imaging findings in patients with mucopolysaccharidosis VI.

Introduction: Mucopolysaccharidosis type VI (MPS VI) is a rare lysosomal storage disorder caused by the deficient activity of N-acetylgalactosamine 4-sulfatase. MPS VI is usually considered as not being associated with mental retardation.

Aims/methods: The main objective of the present study was to describe brain magnetic resonance imaging (MRI) findings and their correlation with clinical and biochemical findings in MPS VI patients.

Sleep abnormalities in untreated patients with mucopolysaccharidosis type VI.

Mucopolysaccharidosis type VI (MPS VI) is a lysosomal storage disease that affects an enzyme responsible for the degradation of glycosaminoglycans (GAGs). Partially degraded GAGs accumulate in several tissues, such as the upper airways (UA), which leads to the development of obstructive sleep apnea (OSA). Our objective was to determine the prevalence of OSA in a group of untreated patients with MPS VI and the association of OSA with clinical and echocardiographic findings.

Mucopolysaccharidosis I, II, and VI: Brief review and guidelines for treatment.

Mucopolysaccharidoses (MPS) are rare genetic diseases caused by the deficiency of one of the lysosomal enzymes involved in the glycosaminoglycan (GAG) breakdown pathway. This metabolic block leads to the accumulation of GAG in various organs and tissues of the affected patients, resulting in a multisystemic clinical picture, sometimes including cognitive impairment. Until the beginning of the XXI century, treatment was mainly supportive.
