Review of agro waste plastic composites production.

This article reviews the literature reports base on agro waste plastic composites using different fiber as fillers and reinforcements. Various processing methods and conditions; compression molding process, injection molding, and extrusion method are used in the composites productions. Characterization challenges associated with the agro waste plastic composites productions were also examined. Thus, the findings of this research review can be use as a data base for further inquiring into the agro waste plastic composites in a view to enhance the development of the sector

Cognitive Algebra Underlying Special Education Teachers' and Psychology Students' Attitudes Towards School Inclusion of People with Intellectual Disability

Attitudes towards regular school inclusion of people with intellectual disabilities (ID) are affected by factors such as disability severity, educational level, and teacher experience. Nevertheless, the ways that teachers integrate these factors to form inclusion judgments remains unclear. The current paper explores what systematic cognitive algebra rules are used to cognitively integrate this set of inclusion factors by special education teachers and psychology students. To do so, 469 special education teachers and psychology students were asked to take part in two experimental cognitive algebra studies. In each study, participants had to read a set of school inclusion scenarios and rate the probability that a scenario actor with ID could be successfully integrated into a regular school program. To this purpose, factor effects on successful school inclusion and ID related to individuality, situational aspects, and contextual considerations (e.g., school environment, grade level taught) were explored. Results suggested that participants showed attitudes to school inclusion ranking from light to moderate positive values. Situational factors, as well as context factors, were judged to be more significant than other factors in elementary education. These factors were integrated by following a cognitive summative rule. Overall, judgment for successful school inclusion follows a summative rule to integrate sources of information. This rule is maintained irrespective of the disability under consideration. However, valuation of each source of information does depend on the type of the current study sample. Implications of these results for inclusion of people with disabilities in regular schools are discussed in this paper

Caracterización clínica y epidemiológica de los pacientes con COVID-19 en un hospital situado en la altura

Objective: To determine the clinical and epidemiological characteristics of patients with COVID-19 at a high-altitude hospital. Materials and methods: An observational, cross-sectional and analytical study carried out at the Hospital Daniel Alcides Carrión in Huancayo, Peru, located at 3,250 m a.s.l. The population consisted of 2,248 people. COVID-19 was diagnosed through serology testing and/or reverse transcription polymerase chain reaction (RT-PCR) testing. Data were recorded in a questionnaire. For the statistical analysis, the X2 test, Student’s t-test, and bivariate and multivariate logistic regression analyses were used. A p value < 0.05 was considered statistically significant. Results: The study population with a diagnosis of COVID-19 accounted for 760 patients (100 %), most of whom were males (474 individuals; 62.36 %). The average age was 49 years (range: 15 to 95). Most cases were found in the age group of 40 to 59 years (38.82 %), particularly among housewives (21.44 %) and traders (19.21 %). The most common COVID-19 symptoms were cough (70.26 %), malaise (57.63 %), respiratory distress (48.81 %), fever (48.15 %) and sore throat (44.21 %). The most frequent comorbidities were obesity (4.47 %), diabetes mellitus (2.76 %) and arterial hypertension (1.31 %). Fifty-one point seven one percent (51.71 %) of the patients required hospitalization and the mortality rate was 14.21 %. The risk factors for mortality were age 60 years or older (OR = 4.74; 95 % CI: 2.94 - 7.65; p = 0.000), respiratory distress (OR = 2.38; 95 % CI: 1.42 - 3.99; p = 0.001) and use of mechanical ventilation (OR = 8.75; 95 % CI: 4.45 - 17.22; p = 0.000). Conclusions: COVID-19 most frequently affects the adult population. Cough and malaise were the most common symptoms, while older age, dyspnea and use of mechanical ventilation were associated with a higher risk of mortality.Objetivo: Determinar las características clínicas y epidemiológicas de los pacientes con COVID-19 en un hospital situado en la altura. Materiales y métodos: Estudio de diseño observacional, transversal y analítico realizado en el Hospital Daniel Alcides Carrión de Huancayo, Perú, ubicado a 3250 m s. n. m. La población estuvo conformada por 2248 personas. El diagnóstico de COVID-19 fue realizado con la prueba serológica y/o la prueba de reacción en cadena de la polimerasa transcriptasa inversa (RT-PCR). Los datos se registraron en un cuestionario. Para el análisis estadístico se emplearon las pruebas de X2 y t de Student, y la regresión logística bivariada y multivariada. El valor de p < 0,05 fue considerado significativo. Resultados: La población con diagnóstico de COVID-19 fue de 760 pacientes (100,00 %). De ellos, los hombres fueron los más afectados con el 62,36 % (474 personas). El promedio de edad fue de 49 años (rango: 15 a 95) y el mayor número de casos se encontró en el grupo etario de 40 a 59 años (38,82 %), sobre todo entre las amas de casa (21, 44 %) y los comerciantes (19,21 %). Los síntomas más comunes de la COVID-19 fueron tos (70,26 %), malestar general (57,63 %), dificultad respiratoria (48,81 %), fiebre (48,15 %) y dolor de garganta (44,21 %). Entre las comorbilidades más frecuentes encontramos obesidad (4,47 %), diabetes mellitus (2,76 %) e hipertensión arterial (1,31 %). El 51,71 % de los pacientes requirió hospitalización y la frecuencia de letalidad fue de 14,21 %. Los factores asociados a un riesgo de mortalidad fueron la edad de 60 años a más (OR = 4,74; IC 95%: 2,94-7,65; p = 0,000), la dificultad respiratoria (OR = 2,38; IC 95%: 1,42-3,99; p = 0,001) y el uso de ventilación mecánica (OR= 8,75; IC95%: 4,45-17,22; p = 0,000). Conclusiones: La COVID-19 afecta con mayor frecuencia a la población adulta. La tos y el malestar general fueron los síntomas más comunes, mientras que la edad avanzada, la disnea y el uso de ventilación mecánica se asociaron a mayor riesgo de letalidad

Effect of a protein supplement on the gut microbiota of endurance athletes: A randomized, controlled, double-blind pilot study

Nutritional supplements are popular among athletes to improve performance and physical recovery. Protein supplements fulfill this function by improving performance and increasing muscle mass; however, their effect on other organs or systems is less well known. Diet alterations can induce gut microbiota imbalance, with beneficial or deleterious consequences for the host. To test this, we performed a randomized pilot study in cross-country runners whose diets were complemented with a protein supplement (whey isolate and beef hydrolysate) (n = 12) or maltodextrin (control) (n = 12) for 10 weeks. Microbiota, water content, pH, ammonia, and short-chain fatty acids (SCFAs) were analyzed in fecal samples, whereas malondialdehyde levels (oxidative stress marker) were determined in plasma and urine. Fecal pH, water content, ammonia, and SCFA concentrations did not change, indicating that protein supplementation did not increase the presence of these fermentation-derived metabolites. Similarly, it had no impact on plasma or urine malondialdehyde levels; however, it increased the abundance of the Bacteroidetes phylum and decreased the presence of health-related taxa including Roseburia, Blautia, and Bifidobacterium longum. Thus, long-term protein supplementation may have a negative impact on gut microbiota. Further research is needed to establish the impact of protein supplements on gut microbiota

Surveillance for Invasive Meningococcal Disease in Children, US–Mexico Border, 2005–20081

We reviewed confirmed cases of pediatric invasive meningococcal disease in Tijuana, Mexico, and San Diego County, California, USA, during 2005–2008. The overall incidence and fatality rate observed in Tijuana were similar to those found in the US, and serogroup distribution suggests that most cases in Tijuana are vaccine preventable
