Background: It is well known that exercise training has positive effects on both cardiac autonomic function and arterial stiffness (AS). However, it is not clear that which exercise training variables, intensity or volume, or both, play a crucial role in this regard. This study investigates the chronic effects of high-volume moderate-intensity training (HVMIT) and low-volume high-intensity training (LVHIT) on heart rate variability (HRV) and AS in sedentary adult men.Materials and Methods: Notably, 45 males (age: 42 ± 5.7 years) were randomly assigned to a control (n = 15), HVMIT (n = 15), or LVHIT (n = 15). The HVMIT group ran three times per week on a treadmill at 50–60% of VO2max for 45–60 min, while the LVHIT trained at 70–85% of VO2max for 25–40 min. Both training protocols were equated by caloric expenditure. HRV, pulse wave velocity (PWV), hemodynamic variables, and body composition were measured before and after 12 weeks.Results: Both protocols (i.e., HVMIT and LVHIT) significantly increased the SD of normal sinus beat intervals (SDNN) and high-frequency (HF) bands (p &lt; 0.05) after 12 weeks. Whereas the low-frequency (LF)-HF ratio decreased significantly in both training protocols (p &lt; 0.05); however, these changes were significantly greater in the LVHIT protocol (p &lt; 0.05). Furthermore, the root mean square of successive RR interval differences (RMSSD) significantly increased only in the LVHIT (p &lt; 0.05). Moreover, a significant decrease in LF and PWV was only observed following the LVHIT protocol (p &lt; 0.05). Some measures of HRV and PWV were significantly correlated (r = 0.275–0.559; p &lt; 0.05).Conclusion: These results show that the LVHIT protocol was more efficient for improving HRV variables and PWV than the HVMIT protocol after 12 weeks of continuous running training. Interestingly, changes in some HRV parameters were related to changes in PWV. Further studies should elaborate on the link between central and peripheral cardiovascular adaptations after continuous and intermittent training regimens differing in intensity.

Published: December 2021

Acute exercise enhances circulating stem and precursor cells (CPCs) in the peripheral blood. The responsible mechanisms and molecular pathways, however, have not been fully identified. The aim of the present study was to investigate a pathway related to elevated levels of apoptotic peripheral blood mononuclear cells (MNCs) and their secretome. An increased uptake of miRNA126 in MNCs was suggested to lead to reduced levels of RGS16 mRNA and, in turn, an enhanced translation and secretion of CXCL12. Eighteen healthy, young men underwent two identical incremental cycling exercises of which the first served as control while the second was preceded by a 7-day-long antioxidative supplementation. Blood samples were collected at baseline (−10min) and several time points after exercise (0, 30, 90, 180, and 270min). Relative concentrations of miRNA126 in MNCs and CXCL12 levels in plasma were determined at all time points while RGS16 mRNA was assessed in MNCs at baseline and 30min after exercise. CXCL12 increased after exercise and strongly correlated with CPC numbers. MiRNA126 increased 30min and, to a lesser extent, also 180 and 270min after exercise but only with supplementation. RGS16 mRNA decreased 30min after exercise independent of the intervention. The amount of RGS16 mRNA inversely correlated with levels of miRNA126, but not with plasma CXCL12. In conclusion, even though plasma CXCL12 correlated with CPC numbers, the increase in CXCL12 cannot be explained by the increased concentration of miRNA126 and lower RGS16 mRNA in MNCs that would have allowed for an enhanced translation of CXCL12.Clinical Trial Registration: ClinicalTrials.gov, NCT03747913.

Introduction: The novel coronavirus SARS-CoV-2 belongs to the coronavirus family, a group of viruses that can cause upper respiratory infections in humans. Among other symptoms, it can present as an asymptomatic infection or as a more severe disease requiring hospitalization. Neuropsychiatric symptoms have been described in the acute phase of the illness and as long-term repercussions. We describe the characteristics and interventions in those COVID-19 patients referred to our liaison psychiatry service.Materials and Methods: This is a cross-sectional descriptive study. This study was carried out within the Department of Psychiatry of Cruces University Hospital (Basque Country, Spain). Data from each psychiatric consultation within our consultation-liaison service were consecutively obtained for 1 month from March 17 to April 17, 2020. We recruited data regarding clinical and referral characteristics and psychiatric interventions.Results: Of a total of 721 SARS-CoV-2 hospitalizations, 43 (5.6%) patients were referred to our psychiatry liaison service. The median age was 61 years old, and 62.8% were women. The infectious disease department was the most frequent petitioner (37.2%), and the most common reason for referral was patient anxiety (25.6%). A total of 67.4% of patients received psychological counseling and 55.8% received some pharmacological approach, with a median of 3.7 visits/calls per patient. In addition, 20.3% needed a medication switch due to potential interactions between psychotropics and drugs used to treat SARS-CoV-2.Discussion: In our study, up to 5.6% of SARS-CoV-2 hospitalized patients needed a psychiatric evaluation, especially for anxiety and mood symptoms. Psychosocial factors associated with the pandemic, drugs used to treat the infection, or a direct causative effect of the virus may explain our findings.

Background: Understanding the direction and magnitude of mental health-loneliness associations across time is important to understand how best to prevent and treat mental health and loneliness. This study used weekly data collected over 8 weeks throughout the COVID-19 pandemic to expand previous findings and using dynamic panel models with fixed effects which account for all time-invariant confounding and reverse causation.Methods: Prospective data on a convenience and snowball sample from all 50 US states and the District of Colombia (n = 2,361 with ≥2 responses, 63.8% female; 76% retention rate) were collected weekly via online survey at nine consecutive timepoints (April 3–June 3, 2020). Anxiety and depressive symptoms and loneliness were assessed at each timepoint and participants reported the COVID-19 containment strategies they were following. Dynamic panel models with fixed effects examined bidirectional associations between anxiety and depressive symptoms and loneliness, and associations of COVID-19 containment strategies with these outcomes.Results: Depressive symptoms were associated with small increases in both anxiety symptoms (β = 0.065, 95% CI = 0.022–0.109; p = 0.004) and loneliness (β = 0.019, 0.008–0.030; p = 0.001) at the subsequent timepoint. Anxiety symptoms were associated with a small subsequent increase in loneliness (β = 0.014, 0.003–0.025; p = 0.015) but not depressive symptoms (β = 0.025, −0.020–0.070; p = 0.281). Loneliness was strongly associated with subsequent increases in both depressive (β = 0.309, 0.159–0.459; p &lt; 0.001) and anxiety (β = 0.301, 0.165–0.436; p &lt; 0.001) symptoms. Compared to social distancing, adhering to stay-at-home orders or quarantining were not associated with anxiety and depressive symptoms or loneliness (both p ≥ 0.095).Conclusions: High loneliness may be a key risk factor for the development of future anxiety or depressive symptoms, underscoring the need to combat or prevent loneliness both throughout and beyond the COVID-19 pandemic. COVID-19 containment strategies were not associated with mental health, indicating that other factors may explain previous reports of mental health deterioration throughout the pandemic.

Background: Low-income earners are particularly vulnerable to mental health, consequence of the coronavirus disease 2019 (COVID-19) lockdown restrictions, due to a temporary or permanent loss of income and livelihood, coupled with government-enforced measures of social distancing. This study evaluates the mental health status among low-income earners in southwestern Uganda during the first total COVID-19 lockdown in Uganda.Methods: A cross-sectional descriptive study was undertaken amongst earners whose income falls below the poverty threshold. Two hundred and fifty-three (n = 253) male and female low-income earners between the ages of 18 and 60 years of age were recruited to the study. Modified generalized anxiety disorder (GAD-7), Spielberger's State-Trait Anger Expression Inventory-2 (STAXI-2), and Beck Depression Inventory (BDI) tools as appropriate were used to assess anxiety, anger, and depression respectively among our respondents.Results: Severe anxiety (68.8%) followed by moderate depression (60.5%) and moderate anger (56.9%) were the most common mental health challenges experienced by low-income earners in Bushenyi district. Awareness of mental healthcare increased with the age of respondents in both males and females. A linear relationship was observed with age and depression (r = 0.154, P = 0.014) while positive correlations were observed between anxiety and anger (r = 0.254, P &lt; 0.001); anxiety and depression (r = 0.153, P = 0.015) and anger and depression (r = 0.153, P = 0.015).Conclusion: The study shows the importance of mental health awareness in low resource settings during the current COVID-19 pandemic. Females were identified as persons at risk to mental depression, while anger was highest amongst young males.

Abstract
We present a path-following interior-point algorithm for solving the weighted linear complementarity problem from the implementation point of view. We studied two variants, which differ only in the method of updating the parameter which characterizes the central path. The implementation was done in the C++ programming language and the obtained numerical results prove the efficiency of the proposed method.

Growth and yield of sesame (Sesamum indicum L.) under the action of two bioles
Resumen
Los estudios sobre alternativas orgánicas de fertilización son una tendencia mundial, por su incidencia favorable en el consumo saludable de alimentos y la preservación del ambiente. En ese contexto se produce esta investigación, cuyo objetivo fue evaluar las respuestas del crecimiento y el rendimiento del ajonjolí (Sesamum indicum L.) a la aplicación de dos bioles. Para ello se empleó un diseño de bloques al azar con tres réplicas y cuatro tratamientos: Biol 1 (estiércol bovino y residuos diversos), Biol 2 (microorganismos eficientes), fertilización química (urea, superfosfato triple y cloruro de potasio 50-25-50) y suelo sin fertilizar. Se evaluaron dos variables del crecimiento (altura de carga y altura de la planta) y cuatro variables del rendimiento (longitud de las cápsulas, cápsulas por planta, semillas por cápsula y rendimiento en t.ha-1). No se obtuvieron diferencias significativas debidas a los tratamientos en las variables del crecimiento. En las variables del rendimiento, la fertilización química produjo rendimientos significativamente superiores a los bioles, y los rendimientos alcanzados con estos fueron siempre superiores a los obtenidos de las plantas no fertilizadas. Se recomienda estudiar el efecto de otras dosis de los bioles y combinarlos cn fertilizantes químicos como alternativa orgánica que permita obtener rendimientos similares a un menor costo ambiental.

Abstract
Studies on organic fertilization alternatives are a global trend, due to their favorable impact on the healthy consumption of food and the preservation of the environment. In this context, this research is carried out, whose objective was to evaluate the growth and yield responses of sesame (Sesamum indicum L.) to the application of two bioles. For this, a randomized block design with three replications and four treatments was used: Biol 1 (bovine manure and various wastes), Biol 2 (efficient microorganisms), chemical fertilization (urea, triple superphosphate and potassium chloride 50-25-50) and soil without fertilizing. Two variables of the growth (height of load and height of the plant) and four variables of the yield were evaluated (length of the capsules, capsules by plant, seeds by capsule and yield in t.ha-1). No significant differences were obtained due to the treatments in the growth variables. In the yield variables, chemical fertilization produced yields significantly higher than bioles, and the yields achieved with them were always higher than those obtained from unfertilized plants. It is recommended to study the effect of other doses of bioles and combine them with chemical fertilizers as an organic alternative that allows to obtain similar yields at a lower environmental cost.

Published: December 2021

La presente investigación se realizó en la Hcda. “El Quemado” ubicada en el cantón Jama, provincia de Manabí, República del Ecuador, en los meses de enero a marzo de la estación invernal del 2011. El objetivo fue lograr medidas alternativas para el fracaso del control químico en controlar daños categorizados como graves con incrementos espectaculares de muertes de palmas en los cultivos de cocotero de la región, causados por el complejo fitosanitario “Gualpa – anillo rojo”. El insecto, gualpa (Rhynchophorus palmarum L.) a más del daño físico en las palmas, también es vector del nemátodo Bursaphelenchus cocophilus Cobb 1919 agente causal de la enfermedad “anillo rojo” que irremediablemente causa la muerte de la palma al bloquear los accesos y fluido de savia en la planta. Entonces la alternativa lógica es experimentar sustancias y/o métodos que permitan capturas del insecto adulto que es el agente causal del complejo fitosanitario.También se establecieron capturas inesperadas del picudo rallado Metamasius sericeus que en otros países también es considerado como vector importante del “anillo rojo”, lo cual induce a que se establezcan sistemas de vigilancia o monitoreo para el seguimiento de este vector, que según reportes se ha establecido que en su estilete y tracto digestivo aloja microorganismos fitopatógenos como bacterias del género Erwinia y Pseudomonas, y de los hongos Fusarium y Ceratocistis.

Published: December 2021

Este proyecto se desarrolló con el objetivo de evaluar el estado higiénico sanitario, infraestructura, operatividad, cumplimiento de la ley de faenamiento en los mataderos municipales de la provincia de Manabí basándose en las normas vigentes en la República del Ecuador y pauta HACCP (Análisis de Peligros, Control de Puntos Críticos), con la finalidad de mejorar las técnicas de faenamiento para obtener un producto de calidad y de buenas bondades organolépticas obteniend los siguientes resultados: Conformidad 8.72%, no conformidad mayor 74.70%, no conformidad menor 16.58%, lo que muestra claramente las falencias que se comenten a diario durante el proceso de faenamiento en bovinos y porcinos, repercutiendo así en el producto final. Una vez obtenidos y analizados estos resultados se elaboró una propuesta en procura de mejoras como la construcción de nuevos mataderos según el Codex Alimentarius y las Normas HACCP, de acuerdo al control de calidad de los productos destinados para el consumo humano. Así mismo se capacitó al personal que labora en los diferentes mataderos de la provincia de Manabí sobre lo relacionado con Buenas Prácticas de Manejo (BPM), Normas de higiene y sanidad, como los Procedimientos Operativos Estandarizados de Saneamiento (POES) entre otros.
