[Strategies for health services in women, newborns, children, and adolescents during the COVID-19 pandemic in countries of Americas].

The article analyzes the perceived challenges and strategies implemented in five Latin American and Caribbean countries to ensure continuity of care and access to health services for women, newborns, children, and adolescents during the COVID-19 pandemic. The study corresponds to a quick assessment based on semi-structured interviews with key informants in countries selected by convenience: Colombia, Ecuador, Guatemala, Grenada, and the Dominican Republic. Interviews were conducted with 23 key informants: (a) decision makers at the national and/or subnational level, (b) healthcare professionals, and (c) representatives of civil society organizations; from December 2020 to January 2021.

Autonomy in Austerity Times. Examining Hormonal Contraceptive Implants in Argentina.

We present findings from a study on the implementation of hormonal contraceptive implants during the last wave of austerity measures in Argentina (2015-2019). Through the lens of "reproductive governance," we discuss continuities and changes in policy discourse that justified the provision of implants from 2014, before austerity measures started to be implemented, and after 2015. Using the concept of "stratified reproduction" in the light of demographic anxiety about teenage pregnancies, we also observe the key role of health professionals in actually enacting in the clinic key policy changes that characterized pregnancy among low-income, young, low-adherence and/or disabled women as a problem to be eradicated.

Therapeutic Role of Neuregulin 1 Type III in SOD1-Linked Amyotrophic Lateral Sclerosis.

Amyotrophic lateral sclerosis (ALS) is a devastating motoneuron (Mn) disease without effective cure currently available. Death of MNs in ALS is preceded by failure of neuromuscular junctions and axonal retraction. Neuregulin 1 (NRG1) is a neurotrophic factor highly expressed in MNs and neuromuscular junctions that support axonal and neuromuscular development and maintenance.

Intrathecal AAVrh10 corrects biochemical and histological hallmarks of mucopolysaccharidosis VII mice and improves behavior and survival.

Mucopolysaccharidosis (MPS) type VII is a lysosomal storage disease caused by ß-glucuronidase deficiency, prompting glycosaminoglycan accumulation in enlarged vesicles, leading to peripheral and neuronal dysfunction. Here, we present a gene therapy strategy using lumbar puncture of AAVrh10 encoding human β-glucuronidase (AAVrh10-GUSB) to adult MPS VII mice. This minimally invasive technique efficiently delivers the recombinant vector to the cerebrospinal fluid (CSF) with a single intrathecal injection.

The Wilms' tumor suppressor gene regulates pancreas homeostasis and repair.

The Wilms' tumor suppressor gene (Wt1) encodes a zinc finger transcription factor that plays an essential role in the development of kidneys, gonads, spleen, adrenals and heart. Recent findings suggest that WT1 could also be playing physiological roles in adults. Systemic deletion of WT1 in mice provokes a severe deterioration of the exocrine pancreas, with mesothelial disruption, E-cadherin downregulation, disorganization of acinar architecture and accumulation of ascitic transudate.
