Evaluation and Analysis of the Effects of Feed Supplements, Including both Organic and Inorganic Selenium, on the Production of Layer Eggs

/in /by

This research aims to evaluate and analyze the provision of additional feed in the form of selenium (Se) on the performance of egg production produced by layers. This research took the main object in the form of 60 weeks old laying hens with the Isa Brown strain. The research was carried out using a Completely Randomized Design (CRD) method with Duncan’s advanced test. The results of this study explain that providing additional feed in the form of selenium (Se) in several doses has a very real influence on egg production performance (egg weight, feed intake, mortality, daily egg production, and FCR). The best dose of selenium was shown in treatment three (commercial feed + organic selenium dose of 150 grams/ton of inorganic selenium feed + vitamin E dose of 1000 grams/ton of feed). The presence of selenium and vitamin E given as additional feed for laying hens can increase egg weight, egg production, minimize mortality rates, and increase appetite.

Analysis of Risk Factors for Death in COVID-19 Patients at Bahteramas Regional General Hospital, Southeast Sulawesi Province

/in /by

Background: Coronavirus disease 2019, or COVID-19, is an infectious disease caused by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). COVID-19 has been classified as a pandemic since 2020.

Purpose:  The purpose of this study was to determine the risk factors for death due to COVID-19 at the Bahteramas Public Hospital, Southeast Sulawesi Province.

Method: This research is a retrospective analytic study with a cross sectional approach. The number of samples is 85 samples. The sampling technique was purposive sampling. The data were processed using the Chi-Square test and Odds Ratio.

Results: This study shows that 47 people died at the Bahteramas Hospital in Southeast Sulawesi Province from March to November 2020, the variable age (p value = 0.001 and OR value 5.216), gender (p value = 0.078 and OR value = 2.180), hypertension variable (p value = 0.071 and OR value = 2.510), and diabetes mellitus variable (p value = 0.013 and OR value = 3.300).

Conclusion: Age, sex, hypertension, and diabetes mellitus are risk factors for death due to COVID-19 at Bahteramas Public Hospital, Southeast Sulawesi Province.

 

Efficacy of Some Plant Extracts Against Stored-Product Pest Red Flour Beetle, Tribolium Confusum (Jacquelin Du Val) (Coleoptera: Tenebrionidae) Adults

/in /by

The efficacy of five plant extracts, Lantana camara, Ruta chalepensis, Rhazya stricta, Heliotropium bacciferum and Marrubium vulgare against Tribolium confusum ware investigated by admixing plant extract with wheat grains. Mortality (%) increased with increasing concentrations, exposure periods and varying from plant to plant. L.camara and R. chalepensis induced the highest percent of mortalities (95.4 and 93.8%) at 500 ppm after 6 days of exposure respectively, for T. confusum, followed by Rh. Stricta, M. vulgare and H. baccifirum. (91.4, 84.5 and 83,3%) respectively. The lowest LC50s were for L. camara and R. chalepensis (114.61 and 117.78 ppm), after 6 days from exposure respectively, followed by Rh. Stricta, M. vulgare and H. bacciferum (175.48, 251.99 and 309.67 ppm respectively. The rate of repellency increased with increase of dose level.  L. camara had the lead in repellent action where repellent percentage was 100 % at 500 ppm followed by R. chalepensiswith, 91%. The repellency rates of other plant extracts were between 50.22 -66.54 at the same concentration which had a moderate repellent action. Statistical analysis showed that all plant extracts revealed significant deference except between H. bacciferum and M. vulgare. Among all the plant extracts L.camara and R. chalepensi were generally more toxic than other plant extracts against T. confusum.

Utilization of Areca Nut Extract on the Control of the Golden Snail Pest (Pomacea canaliculata L), Growth and Production of Rice (Oriza sativa L).

This study aims to determine the effectiveness, the right dose to control the golden snail pest and the impact of its application on rice production. The study was conducted in Teupin Raya Village, Peusangan Siblah Krueng District from September to November 2022. The design used in this study was a non-factorial Randomized Block Design (RBD) with 7 treatments and 3 replications. The factor tested was areca nut extract with the following treatment: P0: Control, P1: Dose of 100 gr/ha P2: Dose of 150gr/ha P3: Dose of 200 gr/ha P4: Dose of 250 gr/ha P5: Dose of 300 gr/ha P6 : Dose of 350 gr/ha. Parameters observed were golden snail mortality, golden snail mortality, attack intensity, plant height (cm), number of tillers, panicle length (cm), and grain weight (g). The results showed that the treatment of various doses of areca extract on mortality, intensity and yield of rice plants had a very significant effect on plant height at 15 and 45 DAP, number of tillers at 15, 30, 45 DAP, panicle length, and grain weight and not significant effect on plant height at the age of 30 HST. The best treatment for the dose of areca extract on the effectiveness, growth and yield of rice plants was obtained in the P6 treatment at a dose of 350 g/plot.

Risk Factor and Clinical Outcomes of Coronavirus Disease 2019 (COVID -19) Patients in TAK Province, Thailand

/in /by

Objective: To describe the association of clinical characteristics, clinical progression, and outcome of COVID-19 patients in TAK province, Thailand
Methods: This retrospective cohort study included patients who were diagnosed with COVID-19 in Tak province, Thailand from June 1, 2021 to December 31, 2021.
Results: The statistical analysis was done on the records of 15,442 patients who underwent RT-PCR of SARS-CoV-2 detection at Tak province during the fourth wave of the outbreak. 53.9% of patients were diagnosed asymptomatic. The overall mortality rate among patients with COVID-19 in this study was 1.81%. Patients with ages over 60 years was associated with increased risk of pneumonia (aOR 5.16, 95% CI 4.52-5.89; P < 0.001) and death (aOR 22.09, 95% CI 12.66-38.53, P < 0.001). Myanmar were also significantly associated with pneumonia (aOR 1.15, 95% CI 1.00-1.33, P < 0.001) and death (aOR 1.99, 95% CI 1.44-2.78, P < 0.001). Chronic Kidney Disease (aOR 3.84, 95% CI 2.31-6.38, P < 0.001) and dyspnea (aOR 4.54, 95% CI 3.27-6.31, P < 0.001) were associated with increased odds of death as well as the presence of more than one comorbidity (aOR 2.87, 95% CI 1.99-4.14, P < 0.001). The previous receipt of vaccination regardless of partially (aOR 0.14, 95% CI 0.08-0 .27; P < 0.001) or fully vaccination (aOR 0.08, 95% CI 0.03-0.19; P < 0.001) was associated with lower odds of mortality. Conclusions: Determining high-risk COVID-19 infected patients can help in the design of appropriate measures and proper management strategies. Ongoing mass vaccination efforts is still an absolutely priority for Thai and non-Thai citizens as a human right to health.
