[Strongyloidiasis as a cause of multiorganic failure].

Strongyloides stercoralis is a parasite that has the ability to reproduce within humans, which explains its persistence for many years. It lives in the duodenum and ileum, between the enterocytes, and opens up to the intestinal lumen. Historically it is associated with tropical and subtropical rural areas, but its development has been seen in microclimates that favour the biological cycle.

[Prevalence and underdiagnosis of burn out syndrome in critical services in the context of the COVID-19 pandemic].

Introduction: The importance of knowing the impact of work on people's health has increased after the COVID-19 pandemic. Burn Out (BO) syndrome arises from the tension emerging from the conflictive interaction between the worker and his or her employment. The objective was to describe the prevalence and frequency of diagnosis of BO in the health human resources of critical services of the Bahía Blanca Municipal Hospital in the context of the COVID-19 pandemic.

New approaches and error assessment to snow cover thickness and density using air temperature data at different heights.

Snow poles are inexpensive systems composed of a wooden mast with temperature sensors affixed at varying heights with the purpose of estimating the snow depth. They are frequently utilised in cold, remote regions where the maintenance of complex monitoring instruments becomes impractical. In this study, snow cover thickness is determined using different methods, based on the thermal behaviour of air temperature measured by a snow pole on Deception Island, Antarctica.

Asymmetrical nucleosomal DNA signatures regulate transcriptional directionality.

Despite the symmetrical structure of nucleosomes, in vitro studies have shown that transcription proceeds with different efficiency depending on the orientation of the DNA sequence around them. However, it is unclear whether this functional asymmetry is present in vivo and whether it could regulate transcriptional directionality. Here, we report that the proximal and distal halves of nucleosomal DNA contribute differentially to nucleosome stability in the genome.

Postnatal clubs: Implementation of a differentiated and integrated model of care for mothers living with HIV and their HIV-exposed uninfected babies in Cape Town, South Africa.

Background: Despite the overall reduction in the HIV mother-to-child transmission (MTCT) rate in South Africa, poor adherence and retention in care during breastfeeding contribute to this period being a major driver of MTCT in South Africa. To improve this retention, postnatal clubs were created as an integrated, differentiated model of care providing psychosocial support and comprehensive care for the mother-infant pairs (MIP), including HIV and under-5-child services. We describe the implementation of these facility-based clubs and examine its health outcomes in a peri-urban primary health care setting in Cape Town, South Africa.

Phase Angle, Inflammation, and Sarcopenia in Late Postoperative Roux-En-Y Gastric Bypass.

Sarcopenic obesity is characterized by a disproportion between the amount of muscle to fat. Contrary to most studies evaluating parameters related to sarcopenic obesity in the elderly, this study aims to evaluate the phase angle (PhA) and sarcopenia in young individuals pre- and post-Roux-en-Y gastric bypass. A total of 69 volunteers (46 women and 23 men; 38.

Accuracy of a Smartwatch to Assess Heart Rate Monitoring and Atrial Fibrillation in Stroke Patients.

(1) Background: Consumer smartwatches may be a helpful tool to screen for atrial fibrillation (AF). However, validation studies on older stroke patients remain scarce. The aim of this pilot study from RCT NCT05565781 was to validate the resting heart rate (HR) measurement and the irregular rhythm notification (IRN) feature in stroke patients in sinus rhythm (SR) and AF.

Interactions between physiology and behaviour provide insights into the ecological role of venom in Australian funnel-web spiders: Interspecies comparison.

Australian funnel-web spiders are iconic species, characterized as being the most venomous spiders in the world. They are also valued for the therapeutics and natural bioinsecticides potentially hidden in their venom molecules. Although numerous biochemical and molecular structural approaches have tried to determine the factors driving venom complexity, these approaches have not considered behaviour, physiology and environmental conditions collectively, which can play a role in the evolution, complexity, and function of venom components in funnel-webs.

Sentence Diversity in Spanish-English Bilingual Toddlers.

Purpose: There remain few available tools to assess language development in Spanish-English dual language learner (DLL) toddlers in the United States. Of interest is the development of early sentences as children move from producing single words to producing multiword utterances. This study is the first to extend sentence diversity to the context of Spanish-English DLLs by describing development from 24 to 30 months of age in children with and without language delays (LDs).

Histopathological survey of parasites harboured by the clam Tawera elliptica (Lamarck, 1818) from Chiloé Archipelago, southeastern Pacific.

Tawera elliptica (commonly known as "Almeja Juliana", is a venerid clam that inhabits sandy bottoms and is distributed from Valparaíso on the Pacific coast up to the Mar del Plata area along the Atlantic coast. Harvests of this clam have declined substantially over the last decade. Therefore, an analysis of common parasites and pathological conditions of this clam was undertaken along with histopathology.

Effect of Sperm Ratio and Temperature on Fertilization and Early Larval Development of the Surf Clam (Bivalvia:Mesodesmatidae).

The effect of sperm ratio on fertilization was evaluated in five sperm:oocytes treatments (10:1, 50:1, 100:1, 500:1 and 1000:1), the effect of temperature on embryonic and larval development in three temperature treatments (13 °C, 16 °C and 19 °C) was recorded and the duration of each stage, the growth rate and survival rate were registered. The oocytes were spherical (67.5 ± 4.

Baroreflex responses of decerebrate rattlesnakes (Crotalus durissus) are comparable to awake animals.

A decerebrate rattlesnake, Crotalus durissus, has previously been used as a model Squamate for cardiovascular studies. It enabled instrumentation for concomitant recordings of diverse variables that showed autonomic responses. However, to validate the preparation and its scope for use, it is necessary to assess how close its cardiovascular variables are to non-decerebrate snakes and the effectiveness of its autonomic responses.

Attrition from Care Among Men Initiating ART in Male-Only Clinics Compared with Men in General Primary Healthcare Clinics in Khayelitsha, South Africa: A Matched Propensity Score Analysis.

Men have higher rates of attrition from antiretroviral therapy (ART) programs than women. In Khayelitsha, a high HIV prevalence area in South Africa, two public sector primary healthcare clinics offer services, including HIV testing and treatment, exclusively to men. We compared attrition from ART care among men initiating ART at these clinics with male attrition in six general primary healthcare clinics in Khayelitsha.

HIV Self-testing Among Previously Diagnosed HIV-Positive People in Khayelitsha, South Africa: No Evidence of Harm but may Facilitate Re-engagement in ART Care.

In South Africa, where an estimated 34% of nearly 7-million HIV-positive people were not on antiretroviral therapy (ART) in 2019, innovative strategies to diagnose and link people to care are needed. HIV self-testing (HIVST) is one such strategy. However, there is concern that access to HIVST might result in re-testing among people on ART, with a risk of false negative results and disengagement from care.

Behaviour of the Sydney funnel-web spider over different contexts, time, and stimuli.

is an iconic Australian spider because the venom can be lethal to humans. Moreover, some of the venom biomolecules have promise as therapeutic and bioinsecticidal leads. Nonetheless, aspects related to the life history and behaviour of this species, which might influence changes in venom components, have been overlooked.

Attrition from HIV care among youth initiating ART in youth-only clinics compared with general primary healthcare clinics in Khayelitsha, South Africa: a matched propensity score analysis.

Introduction: Youth living with HIV (YLWH) are less likely to initiate antiretroviral therapy (ART) and remain in care than older adults. It is important to identify effective strategies to address the needs of this growing population and prevent attrition from HIV care. Since 2008, two clinics have offered youth-targeted services exclusively to youth aged 12-25 in Khayelitsha, a high HIV-prevalence, low-income area in South Africa.

Digital interventions are important tools to promote mental health literacy among university students. "Depression in Portuguese University Students" (Depressão em Estudantes Universitários Portugueses, DEEP) is an audiovisual intervention describing how symptoms can be identified and what possible treatments can be applied. The aim of this study was to evaluate the impact of this intervention.

Genome-wide sequencing analysis of Sgs1, Exo1, Rad51, and Srs2 in DNA repair by homologous recombination.

Homologous recombination is essential to maintain genome stability in response to DNA damage. Here, we have used genome-wide sequencing to quantitatively analyze at nucleotide resolution the dynamics of DNA end resection, re-synthesis, and gene conversion at a double-strand break. Resection initiates asymmetrically in an MRX-independent manner before proceeding steadily in both directions.

A preliminary study of the effects of mindfulness-based cognitive therapy on structural brain networks in mood-dysregulated youth with a familial risk for bipolar disorder.

Background: Mindfulness-based cognitive therapy for children (MBCT-C), as a psychotherapeutic intervention, has been shown to be effective for treating mood dysregulation (MD). While previous neuroimaging studies of MD have reported both pre-treatment structural and functional alterations, the effects of MBCT-C on brain morphological network organisation has not been investigated.

Methods: We investigated brain morphological network organisation in 10 mood-dysregulated youth with familial risk for bipolar disorder and 15 matched healthy comparison youth (HC).

GLP-1: 10-year follow-up after Roux-en-Y gastric bypass.

Purpose: Glucagon-like peptide-1 (GLP-1) is a hormone widely studied in the short-term postoperative follow-up of Roux-en-Y gastric bypass due to its elevation and association with improvement of the glucose metabolism, but there are few studies in 10 years after RYGB follow-up with the same patient.

Methods: Twenty morbidity obesity patients were submitted to RYGB; these patients were divided into two groups: normal glucose-tolerant morbidly obese patients (NGT) 11 patients and abnormal glucose metabolism morbidly obese patients (AGM) 9 patients. Oral glucose tolerance test (OGTT) was done during four different periods: T1 (first evaluation), T2 (pre-surgery), T3 (9 months after surgery) and T4 (10 years after surgery).

Tardigrades exhibit robust interlimb coordination across walking speeds and terrains.

Tardigrades must negotiate heterogeneous, fluctuating environments and accordingly utilize locomotive strategies capable of dealing with variable terrain. We analyze the kinematics and interleg coordination of freely walking tardigrades (species: ). We find that tardigrade walking replicates several key features of walking in insects despite disparities in size, skeleton, and habitat.

Physiological limitations and opportunities in microbial metabolic engineering.

Metabolic engineering can have a pivotal role in increasing the environmental sustainability of the transportation and chemical manufacturing sectors. The field has already developed engineered microorganisms that are currently being used in industrial-scale processes. However, it is often challenging to achieve the titres, yields and productivities required for commercial viability.
