In a study conducted by Majo Carrasco-Tenezaca, Benjamin Bates, Esteban Baus, and Mario Grijalva, barriers and facilitators for home reconstruction in Canton Calvas, Loja, Ecuador were explored. This region is an endemic high-risk area for Chagas disease (CD), a tropical parasitic disease transmitted by triatomine bugs that typically infest precarious housing in rural and impoverished areas.

Diarrheal diseases are one of the main causes of child mortality, primarily affecting children under 5 years of age. Every day, more than 1400 children die worldwide due to diarrhea, which affects approximately 2.5 billion children under 5 years old each year.

In Ecuador, acute diarrhea (AD) and infectious gastroenteritis are significant contributors to pediatric morbidity, accounting for around 15% of outpatient consultations in 2016 and being the second most common cause of pediatric hospitalization in 2019.

Our researchers, Xavier Sánchez, and Ruth Jimbo, conducted a study involving 359 children under 5 years of age, with 58.77% being girls. They found that 85.24% of cases of acute diarrhea (AD) were attributed to infectious and unspecified gastroenteritis and colitis.

In line with international guidelines, the Ecuadorian government has implemented laws and initiatives to promote breastfeeding, especially among working mothers. Despite these efforts, breastfeeding rates in Ecuador remain low. Our researcher María José Mendoza delves into a qualitative study conducted among 60 healthcare professionals in Ecuador who are also mothers. These nurses, physicians, and nutritionists shared their experiences with breastfeeding while managing their demanding careers.

In the study carried out by our researcher Miryan Rivera, an ecological method was developed to manufacture magnetic nanoparticles based on iron oxides (MNPs-Fe), using orange waste. These nanoparticles, proposed as photothermal agents (PTAs) in antibacterial photothermal therapy (PTT), offer a promising solution to a widespread health challenge.

The study introduces a rapid and environmentally friendly green synthesis (GS) method to produce MNPs-Fe from orange waste. Orange peel extract, rich in organic compounds, serves as a multifunctional agent for reduction, capping, and stabilization in the GS process, which is accelerated by microwave (MW) irradiation.

In recent years, microbial diseases have been declared one of the main threats to humanity, which has generated significant interest in the development of nanocomposites with antimicrobial capabilities. The study conducted by our researcher Miryan Rosita Rivera, in collaboration with the Escuela Politécnica Nacional (EPN), focused on two magnetic nanocomposites based on graphene oxide (GO) and multiwall carbon nanotubes (MWCNTs). The synthesis of these magnetic nanocomposites consisted of three phases: firstly, the synthesis of iron magnetic nanoparticles (MNPs); secondly, the adsorption of the photosensitizer menthol-zinc phthalocyanine (ZnMintPc) onto MWCNTs and GO; and the third phase involved encapsulation in a biocompatible poly (N-vinylcaprolactam-co-poly(ethylene glycol diacrylate)) (VCL-co-PEGDA) polymer hydrogel to obtain the magnetic nanocomposites VCL/PEGDA-MNPs-MWCNTs-ZnMintPc and VCL/PEGDA-MNPs-GO-ZnMintPc.

Malaria remains a global health challenge, with staggering statistics of approximately 247 million cases and 619,000 deaths reported in 2021. Plasmodium vivax is the predominant parasite in the Americas, particularly the Southern hemisphere, accounting for 64% of all malaria cases. Ecuador has made significant strides in malaria control, witnessing a remarkable 99% reduction in diagnosed prevalence over the past 15 years. In the article written by our researcher Fabián Sáenz and his colaborator: "Genetic diversity and natural selection of Plasmodium vivax reticulocyte invasion genes in Ecuador", it was discovered that while periodic outbreaks occur in coastal and perennial transmission in the Amazon, the disease mainly affects working-age men in rural areas.
