Impact of breastfeeding on ICU admissions and need for mechanical ventilation in infants younger than 6 months with RSV+ bronchiolitis. An observational study.

Introduction: This work aimed to analyze whether breastfeeding is a predictive factor for admission to ICU or needing mechanical ventilation in children under 6 months with RSV+ respiratory infection.

Methods: A retrospective cohort study was performed in three hospitals. Binary and multiple logistic regression analyses were performed to evaluate the association of variables with admission to the ICU or receiving mechanical ventilation.

Epidemiological Situation of Monkeypox Transmission by Possible Sexual Contact: A Systematic Review.

Monkeypox (MPX), a zoonotic infection caused by the monkeypox virus (MPXV), has re-emerged worldwide with numerous confirmed cases with person-to-person transmission through close contacts, including in sexual networks. Therefore, this study aimed to determine the epidemiological situation of monkeypox transmission by possible sexual contact. A systematic literature review was conducted using PubMed, Scopus, Web of Science, and Embase databases until 18 August 2022.

Ultra-Short Term Evaluation of Coronary Vessel Wall Changes in Reference Segments Adjacent to Culprit Lesions in ST-Segment Elevation Myocardial Infarction.

Background: Culprit lesions of ST-segment elevation myocardial infarction (STEMI) patients are friable, soft, and prone to disruption during primary percutaneous coronary intervention (pPCI). The presence of dissections in reference vessel segments (RVSs), adjacent to stented culprit lesions, and dynamic luminal changes in proximal or distal RVSs have not yet been investigated. We therefore sought to assess the healing patterns of edge dissections and the changes of lumen area at RVSs within 1 week post stent implantation in patients with STEMI.

Affective symptoms and determinants of health-related quality of life in Mexican people with epilepsy.

Epilepsy is known to be associated with multiple psychiatric comorbidities, such as depression, sleep-disorders, and anxiety. The objective of this study was to determine the prevalence and impact of affective symptoms over health-related quality of life (QOL) in Mexican people with epilepsy (PWE). We performed a cross-sectional observational study on 73 consecutive PWE and corresponding age- and sex-matched controls.

Alterations in balance and mobility in people with epilepsy.

Purpose: People with epilepsy (PWE) are burdened by physical disability and side effects of antiepileptic drugs (AED) such as drowsiness and blurred vision. These factors place them at risk for reduced mobility and falls. The purpose of this study was to evaluate mobility and balance in PWE.

Prevalence and impact of irritable bowel syndrome in people with epilepsy.

Purpose: Epilepsy is known to be associated with affective disorders and sleep alterations, as well as with gastrointestinal conditions such as peptic ulcers and inflammatory bowel disease. There is comparatively little evidence linking epilepsy and gastrointestinal functional disorders. The objective of this study was to determine the prevalence and impact of irritable bowel syndrome (IBS) in patients with epilepsy.

Drug-induced haemolysis, renal failure, thrombocytopenia and lactic acidosis in patients with HIV and cryptococcal meningitis: a diagnostic challenge.

Patients with HIV are at risk of both primary and secondary haematological disorders. We report two cases of patients with HIV and cryptococcal meningitis who developed severe haemolytic anaemia, thrombocytopenia, renal failure and lactic acidosis while on treatment with amphotericin B and co-trimoxazole.

Impact of the implementation of the AAN epilepsy quality measures on the medical records in a university hospital.

Background: The American Academy of Neurology (AAN) suggested eight quality measures to be observed at every patient visit. The aim of this work is to compare the percentage of documentation of each measure before and after the implementation of a new worksheet in a third-level center.

Methods: Quasi-experimental study including medical records filled by medical school seniors and junior residents supervised by an epileptologist.

A novel non-synonymous polymorphism (p.Arg240His) in C4b-binding protein is associated with atypical hemolytic uremic syndrome and leads to impaired alternative pathway cofactor activity.

Atypical hemolytic uremic syndrome (aHUS) is a disorder characterized by hemolytic anemia, thrombocytopenia, and acute renal failure. Mutations, polymorphisms, and copy number variation in complement factors and inhibitors are associated with aHUS. In this study, we report the first functional non-synonymous polymorphism in the complement inhibitor C4b-binding protein (C4BP) alpha-chain (c.

The decay accelerating factor mutation I197V found in hemolytic uraemic syndrome does not impair complement regulation.

Hemolytic uremic syndrome is the clinical triad of thrombocytopenia, microangiopathic hemolytic anaemia and acute renal failure. Cases not associated with a preceding Shiga-like toxin producing Escherichia coli are described as atypical HUS (aHUS). Approximately 50% of patients with aHUS have mutations in one of three complement regulatory proteins, Factor H (CFH), membrane cofactor protein (MCP;CD46) or factor I (IF).

Atypical haemolytic uraemic syndrome associated with a hybrid complement gene.

Background: Sequence analysis of the regulators of complement activation (RCA) cluster of genes at chromosome position 1q32 shows evidence of several large genomic duplications. These duplications have resulted in a high degree of sequence identity between the gene for factor H (CFH) and the genes for the five factor H-related proteins (CFHL1-5; aliases CFHR1-5). CFH mutations have been described in association with atypical haemolytic uraemic syndrome (aHUS).

A common CFH haplotype, with deletion of CFHR1 and CFHR3, is associated with lower risk of age-related macular degeneration.

Age-related macular degeneration (AMD; OMIM #603075) is the most frequent cause of visual impairment in the elderly population, with severe disease affecting nearly 10% of individuals of European descent over the age of 75 years. It is a complex disease in which genetic and environmental factors contribute to susceptibility. Complement factor H (CFH) has recently been identified as a major AMD susceptibility gene, and the Y402H polymorphism has been proposed as the likely causative factor.

Determining the antibiotic resistance potential of the indigenous oral microbiota of humans using a metagenomic approach.

Studies of the prevalence and identity of genes encoding resistance to antibiotics in a microbial community are usually carried out on only the cultivable members of the community. However, it is possible to include the as-yet-uncultivable organisms present by adopting a metagenomic approach to such studies. In this investigation, four metagenomic libraries of the oral microbiota were prepared from three groups of 20 adult humans and screened for antibiotic-resistant clones.

Genetic basis of erythromycin resistance in oral bacteria.

We determined the prevalence of erythromycin-resistant bacteria in the oral cavity and identified mef and erm(B) as the most common resistance determinants. In addition, we demonstrate the genetic linkage, on various Tn1545-like conjugative transposons, between erythromycin and tetracycline resistance in a number of isolates.

Novel tetracycline resistance determinant from the oral metagenome.

A major drawback of most studies on how bacteria become resistant to antibiotics is that they concentrate mainly on bacteria that can be cultivated in the laboratory. In the present study, we cloned part of the oral metagenome and isolated a novel tetracycline resistance gene, tet(37), which inactivates tetracycline.

Prevalence of tetracycline resistance genes in oral bacteria.

Tetracycline is a broad-spectrum antibiotic used in humans, animals, and aquaculture; therefore, many bacteria from different ecosystems are exposed to this antibiotic. In order to determine the genetic basis for resistance to tetracycline in bacteria from the oral cavity, saliva and dental plaque samples were obtained from 20 healthy adults who had not taken antibiotics during the previous 3 months. The samples were screened for the presence of bacteria resistant to tetracycline, and the tetracycline resistance genes in these isolates were identified by multiplex PCR and DNA sequencing.

HtrA protease and processing of extracellular proteins of Streptococcus mutans.

A homologue of the HtrA family of stress-response proteases was detected by analysis of the Streptococcus mutans genome sequence. Disabling of the S. mutans htrA gene by insertional inactivation resulted in bacterial clumping in liquid medium, altered colony morphology and a reduced ability to withstand high temperature, extremes of pH or oxidative stress.
