Pharmacogenetic variability of tuberculosis biomarkers in native and mestizo Peruvian populations.

In Peru, 29 292 people were diagnosed with tuberculosis in 2022. Although tuberculosis treatments are effective, 3.4%-13% are associated with significant adverse drug reactions, with drug-induced liver injury (DILI) considered the most predominant.

Antigen-Induced IL-1RA Production Discriminates Active and Latent Tuberculosis Infection.

The IGRA (Interferon Gamma Release Assays) test is currently the standard specific test for infection status. However, a positive test cannot distinguish between active tuberculosis disease (ATBD) and latent tuberculosis infection (LTBI). Developing a test with this characteristic is needed.

Giant cavernous malformation of the posterior fossa with lymphangiomatous phenotype, associated with orbital venolymphatic anomaly in an 11-month-old patient: case report and literature review.

The synchronous presentation of venolymphatic anomalies of the orbit and noncontiguous intracranial cavernous malformations is uncommon. Herein, we present a case of an 11-month-old female patient diagnosed with orbital venolymphatic anomaly associated with a large cavernous malformation in the posterior fossa, who underwent complete surgical resection of the latter. The immunohistochemical analysis was positive for podoplanin, a marker expressed by lymphatic endothelial cells, but not vascular endothelium.

The effect of early-stage public health policies in the transmission of COVID-19 for South American countries.

Objectives: The analysis of transmission dynamics is crucial to determine whether mitigation or suppression measures reduce the spread of coronavirus disease 2019 (COVID-19). This study sought to estimate the basic ( ) and time-varying ( ) reproduction number of COVID-19 and contrast the public health measures for ten South American countries.

Methods: Data was obtained from the European Centre for Disease Prevention and Control.

Response to comment on "genetic variants and source of introduction of SARS-CoV-2 in South America".

During a pandemic, science needs data to generate helpful evidence, and researchers assume this responsibility despite the risk of potential bias. This is the response to the comment made by Pedro Romero, who argued that our manuscript did not use reassembling and mapping strategies for corroborating mutations, and lacked bootstrap support in the phylogenetic analysis.

Genetic variants and source of introduction of SARS-CoV-2 in South America.

After more than 4 months of the COVID-19 pandemics with genomic information of SARS-CoV-2 around the globe, there are more than 1000 complete genomes of this virus. We used 691 genomes from the GISAID database. Several studies have been reporting mutations and hotspots according to viral evolution.

Guillain-Barre syndrome outbreak in Peru: Association with polymorphisms in IL-17, ICAM1, and CD1.

Background: Guillain-Barre Syndrome (GBS) is considered a complex disorder with significant environmental effect and genetic susceptibility. Genetic polymorphisms in CD1E, CD1A, IL-17, and/or ICAM1 had been proposed as susceptibility genetic variants for GBS mainly in Caucasian population. This study explores the association between selected polymorphisms in these genes and GBS susceptibility in confirmed GBS cases reported in mestizo population from northern Peru during the most recent GBS outbreak of May 2018.

Genetics and genomics in Peru: Clinical and research perspective.

Peruvians currently preserve in their DNA the history of 2.5 million years of human evolution and 150,000 years of migration from Africa to Peru or the Americas. The development of Genetics and Genomics in the clinical and academic field is shown in this review.

[Nevoid basal-cell carcinoma syndrome (Gorlin Syndrome): report of two cases and review of the literature].

Gorlin syndrome (GS) is a genetic disorder with an autosomal dominant inheritance pattern, with complete penetrance and variable expressivity. GS is caused by germline mutations in the genes PTCH1 or SUFU, which are components of the Sonic hedgehog molecular pathway. GS is characterized by the presence of multiple nevoid basal cell carcinomas, odontogenic cysts, calcification of the brain sickle, and lesions in the palms and soles.

A Peruvian Child with 18p-/18q+ Syndrome and Persistent Microscopic Hematuria.

Chromosome 18 pericentric inversion carriers could have offspring with recombinant chromosomes, leading to patients with clinical variable manifestations. Patients with 18p-/18q+ rearrangements share some clinical characteristics, while other characteristics differ. Factors for such divergence include the length of the inverted segment, among others.

Parity and Overweight/Obesity in Peruvian Women.

Introduction: The rise in noncommunicable diseases and their risk factors in developing countries may have changed or intensified the effect of parity on obesity. We aimed to assess this association in Peruvian women using data from a nationally representative survey.

Methods: We used data from Peru's Demographic and Health Survey, 2012.

Distribution of Short-Term and Lifetime Predicted Risks of Cardiovascular Diseases in Peruvian Adults.

Background: Short-term risk assessment tools for prediction of cardiovascular disease events are widely recommended in clinical practice and are used largely for single time-point estimations; however, persons with low predicted short-term risk may have higher risks across longer time horizons.

Methods And Results: We estimated short-term and lifetime cardiovascular disease risk in a pooled population from 2 studies of Peruvian populations. Short-term risk was estimated using the atherosclerotic cardiovascular disease Pooled Cohort Risk Equations.

Agreement Between Cardiovascular Disease Risk Scores in Resource-Limited Settings: Evidence from 5 Peruvian Sites.

It is unclear how well currently available risk scores predict cardiovascular disease (CVD) risk in low-income and middle-income countries. We aim to compare the American College of Cardiology/American Heart Association (ACC/AHA) Pooled Cohort risk equations (ACC/AHA model) with 6 other CVD risk tools to assess the concordance of predicted CVD risk in a random sample from 5 geographically diverse Peruvian populations. We used data from 2 Peruvian, age and sex-matched, population-based studies across 5 geographical sites.

[Mandatory requirement of social health service in Peru: discriminatory and unconstitutional].

The rural and urban-edge health service (SERUMS) is an activity that only health professionals perform for the Peruvian government, as it is a mandatory requirement to qualify for a second specialty or to work in public hospitals and public health care facilities, and obtain government scholarships for future training. The few legal changes in the rules of this social program and the focus of “service” restricted to health professionals lead to a perception of this policy as discriminatory and unconstitutional because it violates the right to education and work. There is no scientific evidence that supports the usefulness and effectiveness of this program in terms of quality of service and health indicator improvement, as well as in adequate distribution and retention of health professionals.

Nutritional transition in children under five years and women of reproductive age: a 15-years trend analysis in Peru.

Background: Rapid urbanization, increase in food availability, and changes in diet and lifestyle patterns have been changing nutritional profiles in developing nations. We aimed to describe nutritional changes in children under 5 years and women of reproductive age in Peru, during a 15-year period of rapid economic development and social policy enhancement.

Materials And Methods: Trend analyses of anthropometric measures in children of preschool age and women between 15-49 years, using the Peruvian National Demographic and Family Health Surveys (DHS) from 1996 to 2011.

[Association between television viewing and obesity in Peruvian women].

Objective: To assess the association between frequency of television viewing, overweight and obesity in a nationally representative sample of Peruvian women.

Methods: Secondary analysis of the Demographic and Health Survey 2008 including women aged from 15 to 49 years old. The outcome variables were obesity (body mass index >30 kg/m²) and overweight (body mass index >25 but <30 kg/m²) whereas the exposure variable was frequency of television viewing (never, occasionally, almost every day).

The association between socioeconomic status and obesity in Peruvian women.

Historically in developing countries, the prevalence of obesity has been greater in more advantaged socioeconomic groups. However, in recent years the association between socioeconomic status (SES) and obesity has changed and varies depending on the country's development stage. This study examines the relationship between SES and obesity using two indicators of SES: education or possession assets.
