Coproantigen detection by enzyme-linked immunosorbent assay (coAg ELISA) is a vital tool for detecting and treating cases of Taenia solium taeniasis. However, the assay's procedures require costly materials and sophisticated equipment, which are typically inaccessible in rural settings where the disease is endemic. To overcome these barriers, we developed and evaluated a field-applicable coAg ELISA.

Background: There has been substantial progress in research on preventing violence against women and girls (VAWG) in the last 20 years. While the evidence suggests the potential of well-designed curriculum-based interventions that target known risk factors of violence at the community level, this has certain limitations for working in partnership with communities in low- and middle-income (LMIC) countries, particularly when it comes to addressing the power dynamics embedded within north-south research relationships.

Methods: As an alternative approach, we outline the study design for the EVE Project: a formative research project implemented in partnership with community-based researchers in Samoa and Amantaní (Peru) using a participatory co-design approach to VAWG prevention research.

Background: Occupational exertion is associated with a higher risk of preterm delivery, although studies of leisure time activities generally document reduced risks. Less is known about the risk of preterm delivery immediately following episodes of moderate or heavy physical exertion.

Methods: We conducted a case-crossover study of 722 women interviewed during their hospital stay for early preterm delivery, defined by a gestational age before 34 weeks, and after 20 weeks.

The Global Influenza Initiative (GII) is a global expert group that aims to raise acceptance and uptake of influenza vaccines globally and provides recommendations and strategies to address challenges at local, national, regional, and global levels. This article provides a consolidated estimation of disease burden in Latin America, currently lacking in published literature, and delivers the GII recommendations specific to Latin America that provide guidance to combat existing vaccination challenges. While many countries worldwide, especially in the tropics and subtropics, do not have a seasonal influenza policy, 90% of Latin American countries have a seasonal influenza policy in place.

Wastewater is an important resource in water-scarce regions of the world, and its use in agriculture requires the guarantee of acceptable public health risks. The use of fecal indicator bacteria to evaluate safety does not represent viruses, the main potential health hazards. Viral pathogens could complement the use of fecal indicator bacteria in the evaluation of water quality.

While there is consistent evidence that episodes of physical exertion are associated with an immediately higher risk of acute ischemic vascular events, the risk of placental abruption immediately following episodes of physical exertion has not been studied. In a multicenter case-crossover study, we interviewed 663 women with placental abruption at 7 Peruvian hospitals between January 2013 and August 2015. We asked women about physical exertion in the hour before symptom onset and compared this with their frequency of physical exertion over the prior week.

Pasteurella multocida is a gram-negative, non-motile bacterial pathogen, which is associated with chronic and acute infections as snuffles, pneumonia, atrophic rhinitis, fowl cholera and hemorrhagic septicemia. These diseases affect a wide range of domestic animals, leading to significant morbidity and mortality and causing significant economic losses worldwide. Due to the interest in deciphering the genetic diversity and process adaptive between P.

is one of the most frequently isolated bacteria in acute pneumonia cases, being responsible for high mortality rates in Peruvian young alpacas, with consequent social and economic costs. Here we report the genome sequence of strain UNMSM, isolated from the lung of an alpaca diagnosed with pneumonia, in Peru. The genome consists of 2,439,814 base pairs assembled into 82 contigs and 2,252 protein encoding genes, revealing the presence of known virulence-associated genes (, , , , , , , , and ).

Article Synopsis
  • The study investigates the genetic factors linked to placental abruption (PA) by analyzing SNP variations in circadian clock-related genes in placentas from PA cases and controls.
  • Seven specific SNPs in five genes were found to be associated with PA risk, with one SNP in the RORA gene linked to a 30% reduced risk of PA.
  • The research highlights that both placental and maternal genetic influences contribute to PA risk, with individuals having the highest combined genetic risk showing a significantly increased likelihood of experiencing PA.

Guinea pigs (Cavia porcelus) are an important source of nonhuman animal protein in the Andean region of South America. Specific guidelines regarding the welfare of guinea pigs before and during slaughter have yet to be developed. This study critically assessed the humaneness of 4 different stunning/slaughter methods for guinea pigs: cervical neck dislocation (n = 60), electrical head-only stunning (n = 83), carbon dioxide (CO2) stunning (n = 21), and penetrating captive bolt (n = 10).

Introduction: The circadian clock plays an important role in several aspects of female reproductive biology. Evidence linking circadian clock-related genes to pregnancy outcomes has been inconsistent. We sought to examine whether variations in single nucleotide polymorphisms (SNPs) of circadian clock genes are associated with PA risk.

Article Synopsis
  • The study investigated how often the pH1N1 virus was transmitted between humans and swine on backyard farms in Tumbes, Peru, over a two-year period.
  • Researchers collected samples from swine during four different times: before the pandemic, at its peak, and twice after it, and compared the findings to human infection data.
  • Results showed a significant increase in pH1N1 antibody prevalence in swine during the pandemic period, indicating that human-to-swine transmission occurred, highlighting the need for ongoing monitoring of influenza in these settings.

A 2-week study in rats identified target organs of oxfendazole toxicity to be bone marrow, epididymis, liver, spleen, testis, and thymus. Female rats had greater oxfendazole exposure and exhibited toxicities at lower doses than did males. Decreased white blood cell levels, a class effect of benzimidazole anthelmintics, returned to normal during the recovery period.

While available evidence supports the role of genetics in the pathogenesis of placental abruption (PA), PA-related placental genome variations and maternal-placental genetic interactions have not been investigated. Maternal blood and placental samples collected from participants in the Peruvian Abruptio Placentae Epidemiology study were genotyped using Illumina's Cardio-Metabochip platform. We examined 118,782 genome-wide SNPs and 333 SNPs in 32 candidate genes from mitochondrial biogenesis and oxidative phosphorylation pathways in placental DNA from 280 PA cases and 244 controls.

Objective: The aim of this study was to make an indirect comparison of the results from meta-analyses that evaluated the severity of hot flushes in postmenopausal women exposed to hormone therapy (HT) or soy extracts.

Methods: A systematic review and meta-analysis of HT and soy extracts related to the reduction of hot flushes in postmenopausal women versus the same control (placebo) were conducted. In addition, the combination of the overall results obtained from these two meta-analyses (indirect comparison) was adjusted to the common control (placebo).
