Sheep and goat extensive production systems are very important in the context of global food security and the use of rangelands that have no alternative agricultural use. In such systems, there are enormous challenges to address. These include, for instance, classical production issues, such as nutrition or reproduction, as well as carbon-efficient systems within the climate-change context.

Article Synopsis
  • A new coprological LAMP method called Copro-LAMPAc was developed to detect a zoonotic nematode affecting humans and animals, focusing on DNA extraction and primer design.
  • This method demonstrated an impressive analytical sensitivity of 100 fg and a specificity of 100% when tested against DNA from hosts and other pathogens.
  • When evaluated with canine fecal samples, Copro-LAMPAc proved to be more sensitive than traditional optical microscopy, positioning it as a promising tool for epidemiological studies in areas where the nematode is endemic.

Family Integrated Care (FICare) integrates parents in the direct care of their child while the healthcare personnel act as teachers and guides. To this date, most reports on the feasibility of this model refer to stable preterm infants admitted to Neonatal Intensive Care Units (NICUs). To scale up and adapt FICare to make it suitable in level IIIC NICUs, which care for extreme prematurity and other complex medical or surgical neonatal conditions.

Introduction: Congenital cytomegalovirus (CMV) infection is one of the most common during pregnancy. The infection, particularly in the first trimester, is associated with important sequelae in up to half of the children. Valaciclovir and immunoglobulin have been tested separately for the treatment of fetal CMV infection with relative success.

Cystic echinococcosis (CE) is a parasitic zoonosis caused by Echinococcus granulosus. The control program of CE of Rio Negro province, Argentina, involves annual surveillance using ultrasound (US) screening in school children, and five-year cross-sectional surveys to detect livestock farms with parasitized dogs by coproELISA with confirmation tests (Western Blot or PCR). Control program is based on deworming of dogs with praziquantel and the aim is to identify areas at risk of Cystic echinococcosis transmission to humans, using all available data sources.

Article Synopsis
  • The study aimed to evaluate and compare the effectiveness of PCR and ELISA tests for diagnosing parasites in dog feces across national reference laboratories in Argentina, Chile, Peru, and Uruguay.
  • The results showed poor agreement between the laboratories, with low sensitivity and specificity for detecting the parasites in canine feces, potentially due to differences in testing protocols.
  • The findings highlight the need for standardized diagnostic practices for canine echinococcosis in the region, suggesting that future research should involve fecal samples with established parasite loads to improve testing reliability.

Mechanistic target of rapamycin (mTOR) inhibitors are being used off-label showing promising results in patients with vascular anomalies. Children with lymphatic malformations (LMs) involving the airway benefit from sirolimus therapy soon after birth, reducing the need of tracheostomy. Available information about efficacy and side effects in neonates remains poor.

Cystic echinococcosis (CE) is endemic in the Rio Negro province of Argentina. After 30 years of control using praziquantel in dogs the transmission rate to humans and sheep has decreased significantly, however transmission persists. The objective of the study was to assess the inclusion of the EG95 for sheep in the control program and to determine the vaccine's operative feasibility in field conditions.

Background: Intestinal parasites (IP) have been reported in point studies from different provinces of Argentina. The presence of soil-transmitted helminths (STH) was detected in many of these studies, including varied prevalences of all five species of STH in the north were the climate is more appropriate for transmission. Nonetheless, Argentina lacks a comprehensive prevalence map of STH.

Objective: The aim of this study is to evaluate the use and safety of a sedation protocol with sevoflurane for short painful procedures in newborns.

Study Design: This was a prospective and observational study conducted in a tertiary neonatal intensive care unit. Sevoflurane was recommended in patients undergoing an invasive procedure of short length, especially in those with spontaneous breathing or without venous access.

Background: The acquisition of research skills by midwifery students is increasingly important especially for midwifery programmes in universities. Recently, universities in Chile have included the development of research skills in the majority of professional curricula for basic and post-basic degree programmes. The lack of research training is a limitation recognised and shared with other Latin American countries which prevents scientific and technological development.

Rationale: Infantile-onset Pompe disease, also known as glycogen storage disease type II, is a progressive and fatal disorder without treatment. Enzyme replacement therapy with recombinant human acid alpha-glucosidase (GAA) enhances survival; however, the best outcomes have been achieved with early treatment.

Patient Concerns: We report a case of a newborn with infantile-onset Pompe disease diagnosed in the first days of life who did not undergo universal neonatal screening.

Human Cytomegalovirus (CMV) is the most common cause of intrauterine and perinatal infections worldwide. Postnatal CMV transmission has usually no consequences, but in some cases it may produce disease in preterm infants. Literature reports a broad range of breast milk-acquired CMV infections (5.

Article Synopsis
  • * A quantitative study was conducted in the arroyo El Juncal region, involving fieldwork for collecting data and samples from humans, animals, and the environment, using various diagnostic methods.
  • * Findings revealed an 11.90% prevalence in humans, 5.26% in cattle, and a significant 61.76% in snails, highlighting the need for collaborative efforts to manage and control this zoonotic disease.

Primary intra-osseous carcinoma (PIOC) is a rare tumor, defined as squamous cell carcinoma that develops in the jaw bones, having no initial connection to adjacent skin or mucosa. It is locally aggressive, with metastases to regional lymph nodes, (28% of cases) and lung (5% of cases) at the time of diagnosis. Its origin may be di novo or from other odontogenic tumors.

Sarcocystis sp is a tissue coccidian parasite in humans that causes intestinal and muscular sarcocystosis in immunocompetent patients. Intestinal sarcocystosis can be diagnosed at the tissue level in the lamina propria of the small bowel and by fecal examination. Muscular sarcocystosis is diagnosed by microscopic examination of muscle biopsies.

Overview: In newborns with symptomatic congenital cytomegalovirus (CMV) infection, neuroimaging is the best available predictor of neurodevelopmental outcome. Cerebrospinal fluid (CSF) findings in congenital CMV infection have seldom been described. Neonates with central nervous system infections present high CSF Beta(2)-microglobulin (beta(2)-m) levels.
