2024 Latin American Society of Hypertension guidelines on the management of arterial hypertension and related comorbidities in Latin America.

Hypertension is responsible for more than two million deaths due to cardiovascular disease annually in Latin America (LATAM), of which one million occurs before 70 years of age. Hypertension is the main risk factor for cardiovascular morbidity and mortality, affecting between 20 and 40% of LATAM adults. Since the publication of the 2017 LASH hypertension guidelines, reports from different LATAM countries have confirmed the burden of hypertension on cardiovascular disease events and mortality in the region.

Chemical Profiling, Enzyme Inhibitory Activity and Antioxidant Capacity of South African Herbal Teas: , , and .

Herbal teas are used in South Africa as digestives to lower glycaemia and for other indications. However, the chemical composition of the infusions and their effect on enzymes related to metabolic syndrome is poorly known. The composition of infusions and methanol extracts of (Scrophulariaceae), , , and (Verbenaceae) was assessed and the effect of the infusions and extract was determined towards α-glucosidase, α-amylase, and pancreatic lipase.

Molecular Testing of Environmental Samples as a Potential Source to Estimate Parasite Infection.

We discuss the potential usefulness of molecular testing of soil, dust, and water samples to detect medically important parasites, and where such testing could be used to supplement stool sampling in humans. A wide variety of parasites including protozoa and helminths, many of which are zoonotic, have an important infection reservoir in the environment. In some cases, this environmental period is essential for further parasite development.

B Cell and Antibody Responses in Bovine Tuberculosis.

The development of vaccines and effective diagnostic methods for bovine tuberculosis requires an understanding of the immune response against its causative agent, . Although this disease is primarily investigated and diagnosed through the assessment of cell-mediated immunity, the role of B cells and antibodies in bovine tuberculosis has been relatively undervalued and understudied. Current evidence indicates that circulating -specific antibodies are not effective in controlling the disease.

[Rocabado-penning skull-cervical posture in orthodontic patients].

Introduction: The standing balance of the skull on the spine in its cervical portion is a factor of consideration for the diagnosis of cranio-mandibular disorders and alterations in patients of all ages without distinction, that is, it is essential to conceive an accurate diagnosis in children and adults. However, over time, this element had not been taken into account in the differential diagnosis protocol, despite the fact that biomechanical alterations and dysfunctions in both hard and soft tissues are evidenced in a lateral skull teleradiography, essentially requested to initiate treatment.

Objective: To describe the cranio-cervical posture with the Rocabado-Penning analysis, in patients who come for consultation at the Instituto Latinoamericano de Estudios Superiores (ILES).

sChemNET: a deep learning framework for predicting small molecules targeting microRNA function.

MicroRNAs (miRNAs) have been implicated in human disorders, from cancers to infectious diseases. Targeting miRNAs or their target genes with small molecules offers opportunities to modulate dysregulated cellular processes linked to diseases. Yet, predicting small molecules associated with miRNAs remains challenging due to the small size of small molecule-miRNA datasets.

Bone microstructure analyses in ontogenetic series of Mesosaurus tenuidens from the early Permian of Brazil.

Osteohistological evidence is widely used to infer paleobiological traits of fossil vertebrates, such as ontogeny and growth rates. Mesosaurs, an enigmatic group of aquatic reptiles from the early Permian, are the most well-known Paleozoic amniotes from Africa and South America. Their fossils are abundant in South America, ranging from the central-west region of Brazil to the southernmost areas, as well as parts of Paraguay and Uruguay.

Neurorights in the Constitution: from neurotechnology to ethics and politics.

Neuroimaging technologies such as brain-computer interfaces and neurofeedback have evolved rapidly as new tools for cognitive neuroscience and as potential clinical interventions. However, along with these developments, concern has grown based on the fear of the potential misuse of neurotechnology. In October 2021, Chile became the first country to include neurorights in its Constitution.

Mechanisms of brain self-regulation: psychological factors, mechanistic models and neural substrates.

While neurofeedback represents a promising tool for neuroscience and a brain self-regulation approach to psychological rehabilitation, the field faces several problems and challenges. Current research has shown great variability and even failure among human participants in learning to self-regulate target features of brain activity with neurofeedback. A better understanding of cognitive mechanisms, psychological factors and neural substrates underlying self-regulation might help improve neurofeedback's scientific and clinical practices.

Surgical training trends in the Americas: A cross-continental assessment of minimally invasive surgery and open surgery among surgical trainees.

Introduction: Minimally invasive surgery (MIS) has become standard of care in many high-income countries, but its adoption in low- and middle-income countries (LICs/MICs) has been impeded by resource- and training-related barriers. We hypothesized that trainees in MICs perform MIS procedures less often, and that as procedure complexity increases, the rate of MIS decreases.

Methods: A 22-question survey, distributed to representative leaders across Latin America, collected country-specific graduating trainee case requirements and volumes for four index procedures (cholecystectomy, appendectomy, inguinal hernia repair, colectomy) using MIS or open surgery (OS).

Culture and ICD-11 personality disorder: Implications for clinical practice across diverse ethnic groups.

Background: Personality disorder (PD) in ICD-11 is defined primarily by self and interpersonal dysfunction and optionally by other qualifiers. This definition is inseparable from relativism of cultural determinants.

Aims: This review aimed to synthesize the relevant aspects of the influence of culture on clinical practice and health management for this condition, aligning them to the ICD-11 PD model.

Special Report: Summary of the eighth workshop of the worldwide network for blood and marrow transplantation on the status and issues related to hematopoietic stem cell transplantation in near-east countries, held in Pakistan from September 22 to 23, 2022.

The eighth workshop of the Worldwide Network for Blood and Marrow Transplantation (WBMT) was held in Islamabad, Pakistan, from September 22 to 23, 2022, aiming to foster hematopoietic stem cell transplant (HSCT) activity in the World Health Organization (WHO) Eastern Mediterranean Region (EMRO). Participating countries, including Pakistan, Oman, Iran, and Saudi Arabia, reported increased HSCT in the last few years, whereas others from the EMRO and beyond, including Qatar, United Arab Emirates, Nepal, and Bangladesh, started HSCT recently and have developed HSCT programs with excellent results. During educational sessions and open dialog, participating teams and international experts from the WBMT shared their experience and discussed minimum essential requirements for establishing and expanding HSCT in emerging countries, indications for HSCT training and dissemination of knowledge, stem cell donor selection and safety, quality assurance in transplant centers, and the value and importance of transplant outcome databases.
