Effect of Various Electric Conductivity on Growth and Yield of Pakchoy plant (Brassica rapa L.) With Hydroponic NFT System

Nutrient film technique is one of the hydroponic method that is widely used. Hydroponic vegetable cultivation requires a balanced and adequate nutrition for plants. The accuracy concentration of nutrition can be determined with EC regulation. This study aimed to determine the effect of electric conductivity by regulating the EC levels in the nutrient solution and its effect on growth and yield of pakchoy plant. This research was conducted in a rooftop in Kebon Jeruk, West of Jakarta, from October to November of 2017. The method used was randomized block design (RBD) with one factor namely electric conductivity (EC 1.5; EC 2.0; EC 2.5; EC 3.0) repeated 6 times,. The result showed that electric conductivity treatment in hydroponic formulation with 250 ppm nitrogen (N) effected on parameters of wet weight, height of the plant, width of leaf, shoot root ratio. The highest wet weight was obtained from level e3 (EC 2.5), and this was consistent with most parameters that EC 2.5 showed the best result of all parameters. Therefore it’s clear that by regulating the EC a change will occur for the better or for otherwise

Cardiovascular risk factors and clinical outcomes of patients hospitalized with COVID-19 pneumonia in Somalia

Background: Coronavirus disease-2019 (COVID-19) is a potentially life-threatening illness with no established treatment. Cardiovascular risk factors (CRFs) exacerbate COVID-19 morbidity and mortality. Objective: To determine the prevalence of CRF and clinical outcomes of patients hospitalized with COVID-19 in a tertiary hospital in Somalia. Methods: We reviewed the medical records of patients aged 18 years or older with a real-time polymerase chain reaction (RT-PCR)–confirmed COVID-19 hospitalized at the De Martino Hospital in Mogadishu, Somalia, between March and July 2020. Results: We enrolled 230 participants; 159 (69.1%) males, median age was 56 (41–66) years. In-hospital mortality was 19.6% (n = 45); 77.8% in the intensive care unit (ICU) compared with 22.2%, in the general wards (p < 0.001). Age ⩾ 40 years [odds ratio (OR): 3.6, 95% confidence interval (CI): 1.2–10.6, p = 0.020], chronic heart disease (OR: 9.3, 95% CI: 2.2–38.9, p = 0.002), and diabetes mellitus (OR: 3.2, 95% CI: 1.6–6.2, p < 0.001) were associated with increased odds of mortality. Forty-three (18.7%) participants required ICU admission. Age ⩾ 40 years (OR: 7.5, 95% CI: 1.7–32.1, p = 0.007), diabetes mellitus (OR: 3.2, 95% CI: 1.6–6.3, p < 0.001), and hypertension (OR: 2.5, 95% CI: 1.2–5.2, p = 0.014) were associated with ICU admission. For every additional CRF, the odds of admission into the ICU increased threefold (OR: 2.7, 95% CI: 1.2–5.2, p < 0.001), while the odds of dying increased twofold (OR: 2.1, 95% CI: 1.3–3.2, p < 0.001). Conclusions: We report a very high prevalence of CRF among patients hospitalized with COVID-19 in Somalia. Mortality rates were unacceptably high, particularly among those with advanced age, underlying chronic heart disease, and diabetes

COVID-19 Vaccine Acceptability and Adherence to Preventive Measures in Somalia: Results of an Online Survey

Most countries are currently gravitating towards vaccination as mainstay strategy to quell COVID-19 transmission. Between December 2020 and January 2021, we conducted a follow-up online survey in Somalia to monitor adherence to COVID-19 preventive measures, and COVID-19 vaccine acceptability and reasons for vaccine hesitancy. Adherence was measured via a composite adherence score based on four measures (physical distancing, face mask use, hand hygiene, and mouth covering when coughing/sneezing). We analyzed 4543 responses (mean age: 23.5 ± 6.4 years, 62.4% males). The mean adherence score during this survey was lower than the score during a similar survey in April 2020. A total of 76.8% of respondents were willing to receive the COVID-19 vaccine. Flu-like symptoms were more frequently reported in the current survey compared to previous surveys. Multiple logistic regression showed that participants who experienced flu-like symptoms, those in the healthcare sector, and those with higher adherence scores had higher odds for vaccine acceptability while being a female reduced the willingness to be vaccinated. In conclusion, our data suggest that the decreasing adherence to COVID-19 preventive measures may have caused increased flu-like symptoms over time. COVID-19 vaccine acceptance in Somalia is relatively high but could be improved by addressing factors that contribute to vaccine hesitancy
