Hair cortisol concentration and mental health during childhood and adolescence: evidence that higher cortisol concentration is associated with externalizing problems in a large Brazilian population-based birth cohort.

Childhood and adolescence are pivotal periods for mental health. The hypothalamic-pituitary-adrenal axis is the primary stress system and its chronic activation is measurable via hair cortisol concentration (HCC), indicating long-term stress exposure. While HCC is linked to adult mental health, this relationship remains unclear among youth.

Acute effects of commercial group exercise classes on arterial stiffness and cardiovagal modulation in healthy young and middle-aged adults: A crossover randomized trial.

Background: Arterial stiffness and cardiac autonomic function are crucial indicators of cardiovascular health. Acute exercise and age impact these parameters, but research often focuses on specific exercise activities, lacking ecological validity.

Methods: We examined the acute effects of commercially available group fitness classes (indoor cycling, resistance training, combined exercise) on arterial stiffness and vagal-related heart rate variability (HRV) indices in twelve young and twelve middle-aged adults.

Potential of Annatto Seeds ( L.) Extract Together with Pectin-Edible Coatings: Application on Mulberry Fruits ( L.).

L., or mulberry, is a susceptible fleshy fruit due to its high respiratory rate and low storage stability, which shortens its shelf life and makes it difficult to commercialize in natura. Edible coatings, thin membranes produced directly on the desired surface, could improve food preservation, among other properties.

Challenges of Congenital HHV6 Infection Diagnosis and Treatment: Two Case Reports and Literature Review.

Introduction: Congenital human herpesvirus 6 (HHV6) infection occurs in 1% of the general population and may result from the transmission of an inherited chromosomally integrated HHV6 (iciHHV6) or transplacental infection. It is mostly asymptomatic.

Case Reports: Case 1: a 29th-week-old female preterm newborn, admitted to the neonatal intensive care unit, became clinically unstable and irritable on the 20th day of hospitalization.

Intrauterine Herpes Simplex Virus Infection: Insights Into a Silent Threat.

We report a rare case of congenital herpes simplex virus type 2 (HSV-2) infection in a neonate born to a mother with no clinical evidence of genital HSV infection either before or during pregnancy. Routine prenatal ultrasound assessments in the first two trimesters were unremarkable, and infectious disease screening results were negative. The pregnancy, however, was complicated by premature rupture of membranes (PROM) at 24 weeks of gestation.
