<em>Indonesian Red Cross (PMI) as a partner has a clinic for patients with chronic diseases with regular inspections and education. Diabetes mellitus is one of the most common disease in PMI clinic, with main problems are diet style and medicine compliance. The pandemic has caused the clinic activities stopped; so it is necessary to modify the patients’ educational methods. Limitations in face-to-face education during pandemic, could be overcome by digital-based education. Community service activities were carried out through the identification of partner problems; collecting data on patients or patients' families with WhatsApp numbers, making scripts followed by making videos; distributing the video via Google Drive and Youtube and ended with a discussion session via WhatsApp group. The education contents include menus preparation and managing macronutrient intake and public education in medicine compliance. Changes in knowledge was measured from the results of the pretest and posttest related to the material. The results showed an increase in knowledge of good menu preparation to meet the needs of both macronutrients and micronutrients as well as knowledge of the correct use of diabetes drugs by 20%. These results indicated that the use of video and digital education through WhatsApp group can be an alternative of patients education during pandemic.</em>

Sepak bola merupakan olahraga yang berintensitas tinggi sehingga atlet sepak bola terlebih lagi atlet profesional dituntut memiliki kapasitas aerobik (VO2 Max) yang optimal untuk menampilkan performa maksimal di setiap pertandingan. Salah satu aspek yang dapat memengaruhi VO2 Max adalah persentase lemak tubuh. Tujuan penelitian ini untuk mengetahui pengaruh persentase lemak tubuh terhadap kapasitas aerobik (VO2 Max) atlet sepak bola profesional di Indonesia. Penelitian ini menggunakan metode potong lintang dengan pengumpulan data melalui tes serta pengukuran. Populasi penelitian adalah atlet sepak bola Bhayangkara Football Club yang bermain di Liga 1 Indonesia 2021/2022. Sampel penelitian berjumlah 27 orang dengan teknik sampel jenuh. Persentase lemak tubuh diukur menggunakan metode tebal lipatan kulit (skinfold) Jackson Pollock 7 lokasi. Nilai VO2 Max diukur menggunakan metode Yo-Yo Intermittent Recovery Test Level 2. Rata-rata persentase lemak tubuh atlet Bhayangkara Football Club adalah 9,46 ± 2,38% dengan rumus Brozek dan 8,88 ± 2,57% dengan rumus Siri. Rata-rata VO2 Max atlet adalah 56,36 ± 3,41 ml/kg/min. Hasil analisis data dengan uji Pearson diperoleh korelasi yang bersifat negatif antara persentase lemak tubuh dengan VO2 Max (p = 0,042; r = -0,394). Hal ini menunjukkan semakin rendah persentase lemak tubuh maka semakin baik kapasitas aerobik seorang atlet.

Background: COVID-19 has been shown to increase the risk of thrombosis, where this mechanism occurs due to cell damage that triggers the release of various proinflammatory cytokines and chemokines, thereby activating the coagulation cascade. Thus, an increase D-dimer levels in COVID-19 patients occurs. The duration of patients' hospitalization, known as Length of Hospital Stay (LOS), plays a crucial role in enhancing patient care, reducing overall costs, and optimizing resource allocation. Purpose: The main objective of this study is to determine the correlation between D-dimer and various other factors to assess its predictive value for LOS) in COVID-19 survivors. Methods: This observational analytic study included COVID-19 patients who were admitted to Universitas Sebelas Maret Hospital in Sukoharjo, Indonesia, from November 2020 to January 2021. The data was taken from the medical records of patients diagnosed with COVID-19. Age, gender, comorbidities, admission oxygen saturation, D-dimer, neutrophil-lymphocyte ratio (NLR), haemoglobin, platelet count, white blood cells (WBC), LOS and estimated glomerular filtration rate (eGFR) were analysed in this study. Binary logistic regression was applied to determine the correlation between potential predictors on LOS. Results: A total 104 patients were included in the final analysis. The median LOS was 13 days (IQR 9-17 days). There was an increase of D-dimer in 79 patients with the median 759.39 ng/ml. Patients with prolonged LOS tend to have higher D-dimer levels (Median 924.95 vs 591.54 ng/ml, p = 0.018). However, D-dimer and other parameters was not associated with prolonged LOS in COVID-19 survivors (D-dimer p = 0.188; Age p = 0.138; Diabetes mellitus p = 0.172; NLR p = 0.859; Platelet count p = 0.097). Conclusions: D-dimer levels does not accurately predict prolonged LOS in COVID-19 survivors. Therefore, we suggest D-dimer solely should not be used as a tool to predict patient’s LOS.
