Integrating the exposome and one health approach to national health surveillance: an opportunity for Latin American countries in health preventive management.

The exposome approach, emphasizing lifelong environmental exposures, is a holistic framework exploring the intricate interplay between genetics and the environment in shaping health outcomes. Complementing this, the one health approach recognizes the interconnectedness of human and ecological health within a shared ecosystem, extending to planetary health, which encompasses the entire planet. Integrating Disease Surveillance Systems with exposome, one health, and planetary health signifies a paradigm shift in health management, fostering a comprehensive public health framework.

Vaccine effectiveness in reducing COVID-19-related hospitalization after a risk-age-based mass vaccination program in a Chilean municipality: A comparison of observational study designs.

Background: Case-control studies involving test-negative (TN) and syndrome-negative (SN) controls are reliable for evaluating influenza and rotavirus vaccine effectiveness (VE) during a random vaccination process. However, there is no empirical evidence regarding the impact in real-world mass vaccination campaigns against SARS-CoV-2 using TN and SN controls.

Objective: To compare in the same population the effectiveness of SARS-CoV-2 vaccination on COVID-19-related hospitalization rates across a cohort design, TN and SN designs.

Levels of Small Extracellular Vesicles Containing hERG-1 and Hsp47 as Potential Biomarkers for Cardiovascular Diseases.

The diagnosis of cardiovascular disease (CVD) is still limited. Therefore, this study demonstrates the presence of human ether-a-go-go-related gene 1 (hERG1) and heat shock protein 47 (Hsp47) on the surface of small extracellular vesicles (sEVs) in human peripheral blood and their association with CVD. In this research, 20 individuals with heart failure and 26 participants subjected to cardiac stress tests were enrolled.

Trends in vasectomy and sexually transmitted diseases in Chile: findings from robust national databases.

A controversy about the increase or decline of vasectomy is emerging; however, the evidence is still scarce in Latin America. This ecological study analyzed the vasectomy and sexual transmitted diseases (STD) trends over a period of 10 years in Chile and determined if there is any relationship between them. We conducted a mixed ecological study using secondary and representative data on the number of vasectomies and STD cases from 2008 to 2017.

Towards closing socio-economic status disparities in COVID-19 premature mortality: a nationwide and trend analysis in Chile.

Background: Socio-economic status (SES) disparities in coronavirus disease 2019 (COVID-19) mortality have been reported but complete information and time trends are scarce. In this study, we analysed the years of life lost (YLL) due to COVID-19 premature mortality during the pandemic in Chile and its evolution according to SES and sex compared with a counterfactual scenario [cerebrovascular accidents (stroke)].

Method: We used Chile's national mortality databases from 2020 to 2022.

The added effect of non-pharmaceutical interventions and lifestyle behaviors on vaccine effectiveness against severe COVID-19 in Chile: A matched case-double control study.

Background: World Health Organization approved vaccines have demonstrated relatively high protection against moderate to severe COVID-19. Prospective vaccine effectiveness (VE) designs with first-hand data and population-based controls are nevertheless rare. Neighborhood compared to hospitalized controls, may differ in compliance to non-pharmacuetical interventions (NPI) compliance, which may influence VE results in real-world settings.

Geographical disparities in obesity prevalence: small-area analysis of the Chilean National Health Surveys.

Background: Previous representative health surveys conducted in Chile evidenced a high obesity prevalence rate among adults, especially in female and urban areas. Nevertheless, these have limited utility for targeted interventions and local source allocation for prevention. This study analyzes the increments in obesity prevalence rates in populations ≥15 years of age and the geographic variation at the regional level.

Urinary Extracellular Vesicles as a Source of NGAL for Diabetic Kidney Disease Evaluation in Children and Adolescents With Type 1 Diabetes Mellitus.

Background: Tubular damage has a role in Diabetic Kidney Disease (DKD). We evaluated the early tubulointerstitial damage biomarkers in type-1 Diabetes Mellitus (T1DM) pediatric participants and studied the correlation with classical DKD parameters.

Methods: Thirty-four T1DM and fifteen healthy participants were enrolled.

High Early-onset acromioclavicular secondary pathologies after acute arthroscopic joint reduction: a cohort study.

Purpose: The research aim was to determine the prevalence and risk factors of early secondary acromioclavicular (AC) joint disease in patients undergoing acute arthroscopic AC joint reduction and fixation and early complications of acute surgical treatment in patients with high-grade AC joint dislocation.

Methods: Overall, 102 patients diagnosed with Rockwood type V AC joint dislocation and undergoing arthroscopic coracoclavicular fixation were included. Early clinical and radiological complications were evaluated, as well as risk factors of secondary AC joint pathology.

Development of neutralizing antibody responses against SARS-CoV-2 in COVID-19 patients.

The novel coronavirus severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and coronavirus disease 2019 (COVID-19) are new global problems. The understanding of the host immune response in COVID-19 and its implications in the development of therapeutic agents are new challenges. Here, we evaluated the development of immunoglobulin G (IgG) and neutralizing (Nt) antibodies in symptomatic hospitalized COVID-19 patients.

Severe Acute Respiratory Syndrome Coronavirus 2 Antibody Prevalence in Blood in a Large School Community Subject to a Coronavirus Disease 2019 Outbreak: A Cross-sectional Study.

Background: A severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak affecting 52 people from a large school community in Santiago, Chile, was identified (12 March) 9 days after the first case in the country. We assessed the magnitude of the outbreak and the role students and staff played using self-administered antibody detection tests and a self-administered survey.

Methods: The school was closed on 13 March, and the entire community was placed under quarantine.

[Responsiveness of the chilean version of the International Consultation on Incontinence Questionnaire Short-Form (ICIQ-SF)].

Background: A symptom questionnaire must be able to detect minimal changes after treatment to be clinically useful.

Aim: To evaluate the responsiveness of the Spanish-Chilean version of the ICIQ-SF questionnaire after medical and surgical procedures for the treatment of urinary incontinence (UI) in women consulting at a public Chilean Hospital.

Material And Methods: Data of 124 women aged 59 ± 10 years who were treated for UI and in whom ICIQ-SF questionnaire was applied in two opportunities (before and after medical or surgical treatment), was analyzed.

[Association between the decline in global fertility rate and the incorporation of women to the workforce].

Background: The global fertility rate (GFR) is defined as the mean number of children that a woman could have in a hypothetical cohort, not exposed to death during the fertile period. GFR has fallen from 3.4 to 1.

Differences in body composition and resting energy expenditure in childhood in preterm children born with very low birth weight.

Background: Rapid early ponderal growth is associated with adverse metabolic risks in young adults born at term.

Aim: To determine whether there are differences in body composition, resting energy expenditure (REE) and metabolic variables between preterm children born with very low birth weight (VLBW) either appropriate (AGA) or small (SGA) for gestational age and whether these differences are related to an early period of weight gain.

Methods: 67 VLBW preterm (40 AGA, 27 SGA).

[Interests and perspectives of first and last year medical students].

Background: The interests that motivate medical students to study this career are diverse and they may change during the seven years of study. In Chile, 22 universities offer medicine and the number of graduated students has increased by more than 50% over the last 10 years.

Aim: To determine the motivational profile of medical students at admission, and at the end of their career.
