Antecedentes.

Las enfermedades cardiovasculares (ECV) son la principal causa de morbilidad y mortalidad en la Región de las Américas y la hipertensión es el factor de riesgo modificable asociado más importante. Sin embargo, las tasas de control de la hipertensión siguen siendo bajas y la mortalidad por ECV está estancada o en aumento después de décadas de reducción continua. En el 2016, la Organización Mundial de la Salud (OMS) presentó el paquete técnico HEARTS para mejorar el control de la hipertensión. La Organización Panamericana de la Salud (OPS) diseñó la iniciativa HEARTS en las Américas para mejorar el control del riesgo de ECV, que hace hincapié en el control de la hipertensión y que, hasta la fecha, se ha implementado en 21 países.

Métodos.

Para avanzar en la implementación, se creó un grupo interdisciplinario de profesionales de la salud con el objetivo de seleccionar los factores impulsores claves del control de la hipertensión basados en la evidencia y diseñar un método de puntuación integral para dar seguimiento a su implementación en los centros de atención de salud primaria (APS). El grupo estudió los sistemas de salud de alto desempeño que logran un control elevado de la hipertensión mediante programas de mejora de la calidad que se centran en medidas específicas con respecto a los procesos, con retroalimentación regular a los prestadores en los centros de salud.

Resultados.

Los ocho factores impulsores finales seleccionados se clasificaron en cinco dominios principales: 1) diagnóstico (exactitud de la medición de la presión arterial y evaluación del riesgo de ECV); 2) tratamiento (protocolo de tratamiento e intensificación del tratamiento estandarizados); 3) continuidad de la atención y seguimiento; 4) sistema de prestación del tratamiento (atención basada en un trabajo en equipo, reposición de la medicación) y 5) sistema para la evaluación del desempeño. Los factores impulsores y las recomendaciones se tradujeron en medidas con respecto a los procesos, lo que llevó a dos métodos de puntuación integrados e interconectados en el sistema de seguimiento y evaluación del programa HEARTS en las Américas.

Conclusiones.

El enfoque que se centra en estos factores impulsores clave de la hipertensión y los métodos de puntuación resultantes servirá de guía para el proceso de mejora de la calidad con objeto de alcanzar los objetivos de control a nivel poblacional en los centros de salud participantes de los países que implementan el programa HEARTS.

This study aims to determine the implementation of the Pakis Village Unit Cooperative (KUD) sales system as part of the trade unit and recommend a proposed sales system to strengthen internal control. The accounting records at KUD Pakis still use a manual system that tends to take time, besides that there is no separation of functions and authority in several functions, which are notes that need to be corrected by KUD Pakis. Strengthening of internal control is needed to maintain continuity in a business. These improvements will help make their work easier and protect their assets. This research uses descriptive qualitative research using a case study approach. Based on the results of the study, it can be concluded that the implementation of the sales information system in the trading unit of Pakis village is still manual and requires strengthening of internal control, so that improvements are needed to the implementation of the sales system in the trading unit. Recommendations are given by proposing to entities for documentation and archiving of required documents, implementing a cash sales accounting system by separating job descriptions, namely the sales clerk function with the cashier function, adding a function for recording sales as well as finance and accounting functions.

Garbage is a unique problem in Indonesia. From ordinary waste to limited emergency plastic waste, Indonesia is the second-largest source of plastic waste in the world. Separate collection and disposal of waste is one way to reduce the waste generated by society and industry in Indonesia. Sorting out the types of waste is the first step before the recycling process. In the field of Computer Vision research, it is difficult to see the type and form of waste with a camera, therefore this study aims to overcome this problem by using Deep Learning technology which is expected to be implemented in the whole of Indonesia starting from some of the largest waste-producing cities. Deep Learning is a computer (AI) technique for learning like a human - with experiments being a Part of Machine Learning that can be used to classify images. The method used in this study uses the Convolutional Neural Network (CNN) method which can be used to detect and recognize objects in an image, which can be used to create an automatic waste classification system. Broadly speaking, CNN utilizes the convolution process by moving a convolution kernel (filter) of a certain size to an image, the computer gets new representative information from the results of multiplying that part of the image with the filter used. The test results show that the CNN method can classify inorganic waste with accuracy. 96% and organic waste with an accuracy of 62%.

Employee performance is one element that greatly determines the quality of an organization, both government and private. Employee performance appraisal has become a routine for most companies. Performance appraisal is required for the process of salary increases, promotions, and demotions. Until this research was carried out, the processing of employee performance appraisal and evaluation at Prasama Bhakti Foundation was still done manually, so that sometimes employee promotions were carried out late or even on an inconsistent basis for each employee. Therefore, it is necessary to group data with the help of machine learning that can help predict the eligibility of an employee to get a promotion based on his performance. Classification is one method for classifying or classifying data that are arranged systematically. Decision tree and logistic regression methods are classification or grouping methods that have been widely used for solving classification problems. In this study, it will be explained how the process of processing employee performance appraisal data starts from data preparation to determine the accuracy of the decision tree model and logistic regression that is formed. The two classification models are used to predict employee performance as a recommendation for employee promotion at the Prasama Bhakti Foundation.

Published: May 2022

This paper aims to study the behavior of one-way concrete solid slabs reinforced with welded wire mesh to investigate the efficiency of using welded wire mesh in the construction of structural slabs as a replacement for ordinary steel bars. This research included experimental and analytical programs. Nine 700×1050 mm one-way simple specimens and six 525×1050 mm continuous one-way slabs with two equal spans were tested under point, line, and uniform static loads. The experimental program studied the use of welded mesh and the number of layers utilized. Numerical analysis was conducted using finite element modeling developed using the ABAQUS 6.13 software package. Experimental and analytical results showed good correlation: the number of layers of welded metal mesh and load type significantly affected the peak vertical load capacity of simple and continuous slabs, with slabs showing higher values with welded mesh than those of ordinary reinforcing bars. In addition, using welded metal mesh to reinforce solid slabs enhanced their cracking behavior as well as their ductility. Doi: 10.28991/CEJ-2022-08-04-03 Full Text: PDF

Long bean (Vigna sinesis L.) is a horticultural plant that is easy to cultivate. Cultivation of long bean plants certainly has several factors that can reduce production yields such as environmental factors, pest attacks, and diseases. This study aims to determine the pests and diseases that generally attack long bean plants and the symptoms they cause. This study used direct observation method (Systematic sampling) to determine the percentage of pest and disease attacks on long bean plants. From the total number of plants in the location, 5 plant samples were taken to be observed. Based on the pest and disease identification research that has been carried out, it was found that some of the symptoms that arise due to pest/disease attacks on most of the long bean plants were found. Symptoms that appear include damage to flower buds and leaves with holes caused by black ladybugs (Brachyplatys sp.); leaf curl, leaves and stems turn black due to aphids (Aphis craccivora); jagged leaf edges, and holes caused by grasshoppers (Oxya sp.) and lasiocampidae caterpillars; thickening of the leaf veins on young leaves, leaves shrinking caused by Bean Common Mosaic Virus (BCMV); The leaves turn yellow and the bone blanching occurs due to the Mungbean Yellow Mosaic Virus (MYMV).

Published: May 2022

SARS-CoV-2 is a virus that has a positive-sense, single-stranded RNA genome that encodes 4 structural proteins, the main one being the S protein (Spike) responsible for mediating with ACE2 and TMPRSS2 for entry into the host cell. The study of single nucleotide polymorphisms (SNPs) of ACE2 and TMPRSS2 can elucidate their possible intervention in the action of the protein, its activity, and the gene expression of encoding these enzymes, which may increase susceptibility to viral infection. From this, literature searches were carried out until December 2021, listing 11,820 publications for literary analysis on the described genetic variations of these protein structures, as well as their relation and influence on the pathology. It was possible to conclude that there is a great influence exerted by genetic variability in ACE2 and TMPRSS2 increasing the ability of the virus to bind to the host cell and the development of COVID-19 with complications.

Cardiac angiosarcomas are rare malignant neoplasms with an aggressive clinical course. These are characterized by the absence of specific clinical findings, rapid growth with frequent metastasis at the time of diagnosis, correlated with poor prognosis, and reduced response to treatment. But with early diagnosis, more possibilities for treatment and survival can be provided. We report the case of a young woman diagnosed with right atrial angiosarcoma locally advanced with bone metastases detected by 18F-FDG PET/CT, which revealed distant disease extent at diagnosis, consequently, chemotherapy was started.

Background

Poor nutritional habits and related hygiene and sanitation practices impair food and nutrition security, and increase the risk of foodborne diseases and related school absenteeism. While the WASH program promoted by the UNICEF boosts water, sanitation, and hygiene, only a few studies thus far encouraged healthy eating habits and safe and nutritious meals at school. This study aimed at combining education of schoolchildren on nutrition and hygiene (nutrition knowledge, attitudes, practices; food choices; nutrient sources; dental care; handwashing), and at boosting the engagement of parents and teachers in the promotion of nutrition-related behaviors conducive to health and well-being.

Methods

Four primary schools in different Yaoundé Urban Councils and 71 schoolchildren aged 7-12 years enrolled in the study. In this paper we report on the i) administrative and ethical clearance, ii) sensitisation and demonstration activities, iii) donation of WASH equipment, disposable materials for hand and teeth hygiene, toolkit policy, and guidebook, iv) baseline assessment by structured questionnaire, v) combined course (1 hour/week, 6 weeks), and vi) measured impact. Scores were analysed using paired z- and t-tests with SPSS 23.0 for windows.

Results

In the four schools, handwashing showed the best improvement. Older children benefited more from the whole course, while the improvement in younger children focused more on practices. The school that scored lowest at baseline obtained marked general improvement. Interestingly, general improvement in food choices coupled with persistent difficulty in recognising nutrient sources. Although sociocultural and socioeconomic parameters were not included in the questionnaire, these emerged as possible modifiers. Despite limited hours of direct training and limited resources invested, this short-term intervention significantly changed habits of children and the school community. Availability of hand and teeth hygiene materials facilitated and motivated the proactivity of the school community to boost good nutrition and hygiene practices sustainably.

Conclusions

Preventive medicine is a balance of awareness and affordability. Having this in mind, more coordinated efforts (WASH, food safety, food security) will enforce proper nutrition and hygiene of children at school in the different Cameroonian sociocultural and socioeconomic settings.

Spirulina contains a rich source of crude protein (58.94%), followed by chlorella (47.08%) and azolla (21.82%). The content of crude fat was higher in chlorella (5.68%), followed by azolla (4.00%) and spirulina (1.54%). The crude fibre level was found to be higher in azolla (26.21%), followed by chlorella (2.87%) and spirulina (1.00%). The gross energy was higher in chlorella (4,377 kcal/kg), followed by spirulina (4,183 kcal/kg) and azolla (3,295 kcal/kg). The secondary phytochemical analysis revealed presence of alkaloids, terpenoids, flavonoids, tannis, polyphenols, saponins, cardiac glycoside and quinones in these algae at different levels. The GC-MS analysis showed presence of 11 metabolic compounds, of which 5 from petroleum etheric extract and 6 from methanolic extract. The chlorella showed presence of 14 secondary metabolites, of which 5 from petroleum etheric extract and 9 from methanolic extract. In azolla, there were 13 secondary metabolic compounds, of which 6 from petroleum etheric extract and 7 from methanolic extract. Therefore, a total of 38 secondary metabolites, which includes 12 different bioactive principle compounds, were identified in these algae. Docosane was found to be present both in spirulina and azolla. Similarly, Tetradecanoic acid was found to be present both in spirulina and chlorella. The remaining ten bioactive principle compounds are species specific, such as 9-octadecenal; and Hexadecanoic acid are for spirulina, Dodecanoic acid; 6,7-Dimethoxy-2-tetralone; 3,7,11,15-Tetramethyl-2-hexadecen-1-ol; Phenol, 2-methoxy-5-(1-propenyl)-,(E); Cycloheptane,1,3,5-tris(methylene); 4-(6,6-Dimethyl-2-methylenecyclohex-3-enylidene)pentan-2-ol; and Loliolide are for chlorella, and cis-2-[2-(hydroxymethyl)cyclopentyl]ethanol is for azolla. Thus, these algae are rich in natural organic compounds. Their pharmaceutical and nutraceutical potencies need to be studied.

The study was conducted to evaluate the anti-diarrhoeal and gastrointestinal motility slowing effects of the ethanol leaf extract of D. guineense in Wistar rats. The anti-diarrhoeal and gastrointestinal motility slowing effects of the ethanol leaf extract of D. guineense were evaluated using castor oil-induced diarrhoeal model, charcoal meal, and anti-enteropooling tests in Wistar rats. The test groups received various doses (100, 200, and 400 mg/kg) of the extract whereas positive controls received Loperamide (4 mg/kg) or Atropine (5 mg/kg) and negative controls received Normal Saline (10 ml/kg). The phytochemical screening as well as the acute toxicity test of the extract was also performed. The extract produced a dose-dependent significant reduction in the watery nature and frequency of fecal droppings in the castor oil-induced diarrhea. On gastrointestinal transit time and enteropooling, the extract also dose-dependently reduced the small intestinal transit of charcoal meal and intestinal fluid volume in a manner comparable to 5 mg/kg of atropine sulphate and 4 mg/kg of loperamide. The acute toxicity study on the extract revealed an oral LD50 value greater than 5000 mg/kg in mice. The phytochemical constituents detected in the extract were tannins, phenols, resin, alkaloids, saponins, terpenoids, and glycosides. The findings from this study showed that the ethanol leaf extract of D. guineense possesses anti-diarrhoeal properties and thus supports the traditional application of the leaf extract in the treatment of diarrhea in Nigeria.

Cattleya sp. orchid is one type of orchid plant that is widely known in Indonesia. The queen of orchids is the nickname given to the Cattleya sp. orchid because of the elegant shape and color of the flowers of the Cattelya sp. orchid. This research was conducted to determine the level of reducing sugar produced by plantlets of Cattleya sp. after the addition of fusaric acid in in vitro media. Determination of reducing sugar content was carried out using the Nelson – Somogyi method. This study used a completely randomized design (CRD), with five levels of treatment and five replications for each level. The treatment consisted of adding fusaric acid with concentrations of fusaric acid in the medium: 0 ppm, 10 ppm, 20 ppm, 30 ppm and 40 ppm. Data analysis used Anova analysis, and continued with Tukey's test at 5% significance level. Based on the analysis, there was an increase in reducing sugar levels in the plantlets of Cattleya sp. orchids after adding fusaric acid to the growing media.
