[Use of screens, sedentary lifestyle, and physical activity in children under six years of age, during the period of preventive and compulsory social isolation in AMBA: online survey].

Introduction: Within the context of the COVID-19 pandemic, children were confined to their homes. The Buenos Aires Metropolitan Area (AMBA) region has the highest urban density in Argentina and has been the epicenter of COVID-19 infections and deaths. The objectives of this study are to characterize the habits of screen use, sedentary lifestyle and physical activity and describe their associations, in children under six years of age from AMBA, Argentina.

Longitudinal findings of a U.S. preventive evidence-based family intervention tested among youth in Ecuador: Familias Unidas.

Interventions that address adolescent conduct problems are essential for decreasing negative risk behaviors and promoting positive protective factors among youth. Although interventions have been developed and tested in the United States, preventive evidence-based interventions (EBIs) are less available in Latin American countries such as Ecuador. Therefore, the purpose of this study was to evaluate the efficacy of an evidence-based, parent-centered intervention, Familias Unidas, in preventing/reducing conduct problems, across time, among youth in Guayaquil, Ecuador.

Molecular insight into cellulose degradation by the phototrophic green alga Scenedesmus.

Lignocellulose is the most abundant natural biopolymer on earth and a potential raw material for the production of fuels and chemicals. However, only some organisms such as bacteria and fungi produce enzymes that metabolize this polymer. In this work we have demonstrated the presence of cellulolytic activity in the supernatant of Scenedesmus quadricauda cultures and we identified the presence of extracellular cellulases in the genome of five Scenedesmus species.

Using the PDCA cycle to uncover sources of mental health disparities for Hispanics.

The Hispanic population is growing rapidly in U.S. rural states, yet limitations in Spanish-speaking behavioural health providers are a barrier to accessing care.

The Florida Clinical Skills Collaborative: A New Regional Consortium for the Assessment of Clinical Skills.

Discontinuation of the United States Medical Licensing Examination (USMLE) Step 2 Clinical Skills (CS) exam and Comprehensive Osteopathic Medical Licensing Examination (COMLEX) Level 2 Performance Evaluation (2-PE) raised questions about the ability of medical schools to ensure the clinical skills competence of graduating students. In February 2021, representatives from all Florida, United States, allopathic and osteopathic schools initiated a collaboration to address this critically important issue in the evolving landscape of medical education. A 5-point Likert scale survey of all members (n=18/20 individuals representing 10/10 institutions) reveals that initial interest in joining the collaboration was high among both individuals (mean 4.

Identifying service quality gaps between patients and providers in a Native American outpatient clinic.

Background: Native American communities in Montana reservations have reported low-level satisfaction in health services. This research explored if the services provided at a Blackfeet Indian Reservation outpatient clinic were designed to meet patient expectations.

Methods: Staff and patient interviews and surveys allowed service expectations to be assessed according to the clinic's ability to meet those expectations.

Rural Hispanic Perceptions of Mental Health: A Qualitative Study.

Introduction: In 2020, 18.4% of Hispanics experienced mental illness, yet only about a third received treatment compared with nearly half of non-Hispanic Whites. In Montana, where only 11% of the mental health needs are currently met, service utilization is low.

CBM20CP, a novel functional protein of starch metabolism in green algae.

Ostreococcus tauri is a picoalga that contains a small and compact genome, which resembles that of higher plants in the multiplicity of enzymes involved in starch synthesis (ADP-glucose pyrophosphorylase, ADPGlc PPase; granule bound starch synthase, GBSS; starch synthases, SSI, SSII, SSIII; and starch branching enzyme, SBE, between others), except starch synthase IV (SSIV). Although its genome is fully sequenced, there are still many genes and proteins to which no function was assigned. Here, we identify the OT_ostta06g01880 gene that encodes CBM20CP, a plastidial protein which contains a central carbohydrate binding domain of the CBM20 family, and a coiled coil domain at the C-terminus that lacks catalytic activity.

Biased cytochrome P450-mediated metabolism via small-molecule ligands binding P450 oxidoreductase.

Metabolic control is mediated by the dynamic assemblies and function of multiple redox enzymes. A key element in these assemblies, the P450 oxidoreductase (POR), donates electrons and selectively activates numerous (>50 in humans and >300 in plants) cytochromes P450 (CYPs) controlling metabolism of drugs, steroids and xenobiotics in humans and natural product biosynthesis in plants. The mechanisms underlying POR-mediated CYP metabolism remain poorly understood and to date no ligand binding has been described to regulate the specificity of POR.

Open-label phase 3 study of intravenous golimumab in patients with polyarticular juvenile idiopathic arthritis.

Objectives: To assess efficacy, pharmacokinetics (PK) and safety of intravenous (i.v.) golimumab in patients with polyarticular-course JIA (pc-JIA).

Exploring a rural Latino community's perception of the COVID-19 pandemic.

Objectives: The purpose of our study was to understand the perception of the Latino community in a rural state regarding COVID-19. Over one third of national COVID-19 cases are among Latinos, likely due to an increased prevalence of comorbid risk factors and social determinants of health that make following precautions difficult.

Design: Respondents were recruited using snowball sampling as part of a previous effort to establish an academic-community partnership with Latinos in the area.

Feasibility of a Noninvasive Operability Assessment in Chronic Thromboembolic Pulmonary Hypertension under Real-World Practice.

This study aimed to evaluate the feasibility of a noninvasive operability assessment of chronic thromboembolic pulmonary hypertension (CTEPH) based on multidetector computed tomographic angiography (MCTA). Up to 176 patients were evaluated from January 2016 to April 2018. Throughout the first phase, the initial surgical decision was made based on MCTA with further analysis of pulmonary angiography (PA) in order to evaluate in which cases the initial decision was not modified by PA.

Results of a Family-Based Intervention Promoting Healthy Weight Strategies in Overweight Hispanic Adolescents and Parents: An RCT.

Introduction: Hispanic adolescents in the U.S. are disproportionately affected by overweight and obesity compared with their White, non-Hispanic counterparts.

The Influence of Drying Temperatures on the Metabolic Profiles and Antioxidant Activity of Leaves.

In the present study, the leaves of (L.) P. Royen (Sapotaceae), an evergreen tree recognized for its medicinal properties in Southern Mexico, were used as a model to study the effect of different drying temperatures on its metabolic profile and therefore, its antioxidant potential.

Brief Underage Alcohol Use Screener Scores Predict Health Risk Behaviors.

The aim of this study was to determine if adolescents' scores on a 2-item underage alcohol use screener predict risky consequences of past-year alcohol use and other health risk behaviors in a nonclinical, school-based sample of adolescents. A predominantly minority sample of 756 middle and high school students completed in-school tablet-based surveys on past-year underage alcohol use and a range of health risk behaviors. Higher scores for self alcohol risk and peer alcohol risk were associated with higher risk of past-year riding with a drunk driver and past 90-day measures of cigarette use, marijuana use, unplanned sex, and unprotected intercourse.

Variability in human drug metabolizing cytochrome P450 CYP2C9, CYP2C19 and CYP3A5 activities caused by genetic variations in cytochrome P450 oxidoreductase.

A broad spectrum of human diseases are caused by mutations in the NADPH cytochrome P450 oxidoreductase (POR). Cytochrome P450 proteins perform several reactions, including the metabolism of steroids, drugs, and other xenobiotics. In 2004 the first human patients with defects in POR were reported, and over 250 variations in POR are known.

Starch Synthesis in : The Starch-Binding Domains of Starch Synthase III-B Are Essential for Catalytic Activity.

Starch is the major energy storage carbohydrate in photosynthetic eukaryotes. Several enzymes are involved in building highly organized semi-crystalline starch granules, including starch-synthase III (SSIII), which is widely conserved in photosynthetic organisms. This enzyme catalyzes the extension of the α-1,4 glucan chain and plays a regulatory role in the synthesis of starch.

Familias Unidas for Health and Wellness: Adapting an Evidence-Based Substance Use and Sexual Risk Behavior Intervention for Obesity Prevention in Hispanic Adolescents.

We describe the adaptation of Familias Unidas, an evidence-based substance use and sexual risk behavior intervention, for obesity prevention in Hispanic adolescents. Intervention developers and experts in pediatric obesity, exercise physiology, dietetics, and the local parks system provided input for changes. Hispanic families also provided input through a series of 21 focus groups conducted before, during, and after an initial pilot test of the adapted intervention.

eHealth Familias Unidas: Efficacy Trial of an Evidence-Based Intervention Adapted for Use on the Internet with Hispanic Families.

While substance use and sexual risk behaviors among Hispanic youth continue to be public health concerns, few evidence-based preventive interventions are developed for and implemented with Hispanic/Latino youth. The objective of this study was to evaluate the efficacy of eHealth Familias Unidas, an Internet adaptation of an evidence-based family intervention for Hispanics. A randomized controlled trial design (n = 230) was used to evaluate intervention effects on substance use and condomless sex among a sample of Hispanic eighth graders with behavioral problems.

Informed consent comprehension among vulnerable populations in Ecuador: video-delivered vs. in-person standard method.

The informed consent comprehension process is key to engaging potential research subject participation. The aim of this study is to compare informed consent comprehension between two methods: standard and video-delivered. We compared the in-person and video-delivered informed consent process in the Familias Unidas intervention.

[Combination of phosphorus solubilizing and mobilizing fungi with phosphate rocks and volcanic materials to promote plant growth of lettuce (Lactuca sativa L.)].

Arbuscular mycorrhizal fungi (AMF) increase the uptake of soluble phosphates, while phosphorus solubilizing fungi (S) promote solubilization of insoluble phosphates complexes, favoring plant nutrition. Another alternative to maintaining crop productivity is to combine minerals and rocks that provide nutrients and other desirable properties. The aim of this work was to combine AMF and S with pyroclastic materials (ashes and pumices) from Puyehue volcano and phosphate rocks (PR) from Rio Chico Group (Chubut) - to formulate a substrate for the production of potted Lactuca sativa.
