Neuroactive hormones and personal growth: associations in Chilean adolescents (ages 12-25) with ovulatory dysfunction.

Introduction: Hormones produced by the hypothalamic-pituitary-adrenal-gonadal (HPAG) axis are crucial for modulating central nervous system (CNS) function and development throughout a person's life. Disruptions in HPAG function can impact psychological development, particularly during adolescence-a period marked by psychological growth and the maturation of the HPAG axis. An early indicator of HPAG alterations is ovulatory dysfunction (OD), a common condition among adolescents.

Parasite Burdens of Several Triatomine Species in Colombia.

, the causal agent of Chagas disease, is mainly transmitted by insects of the Triatominae subfamily. In Colombia, there are 26 triatomine species, and 16 of them are naturally infected with the parasite. The parasite loads of naturally infected vectors can be significant in targeting specific species that can affect the epidemiology of the disease.

Chronic Stress and Ovulatory Dysfunction: Implications in Times of COVID-19.

Stress is known to be associated with adverse health outcomes. The COVID-19 pandemic and its associated lockdowns are examples of chronic stressors. Lockdown measures inadvertently caused significant psychological distress and became a powerful source of anxiety/stress, sleep disturbances, nutritional changes and weight gain.

Earthquake segmentation in northern Chile correlates with curved plate geometry.

We performed an integrated analysis of the coseismic slip, afterslip and aftershock activity of the 2014 M 8.1 Pisagua earthquake. This earthquake seems to be spatially located between two major historical earthquakes, the 1868 M 8.

Untangling the transmission dynamics of primary and secondary vectors of Trypanosoma cruzi in Colombia: parasite infection, feeding sources and discrete typing units.

Background: Trypanosoma cruzi is the causative agent of Chagas disease. Due to its genetic diversity has been classified into six Discrete Typing Units (DTUs) in association with transmission cycles. In Colombia, natural T.

[Investigation of vectors and reservoirs in an acute Chagas outbreak due to possible oral transmission in Aguachica, Cesar, Colombia].

Colombia recorded 11 cases of acute Chagas disease and 80 cases of oral contamination with Trypanosoma cruzi. The current study analyzes the entomological and parasitological characteristics of the outbreak in Aguachica, Cesar Department, in 2010. An interdisciplinary group of health professionals and regional university personnel conducted the laboratory tests in the patients and the investigation of the transmission focus.

Infestation by triatomine bugs in indigenous communities of Valledupar, Colombia.

Objective: To calculate triatomine infestation indices in indigenous communities in Colombia.

Methods: A descriptive study was carried out in 19 communities in Valledupar Municipality, Cesar Department, Colombia. During June to December, 2007, triatromine bugs were collected from their resting places in households.
