Introduction Coronavirus Disease (COVID-19) caused by Novel Coronavirus named as Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) was declared Pandemic by The World Health Organization (WHO) and a Public Health Emergency of International Concern (PHEIC) on January 30, 2020. Many COVID-19 vaccines have been developed, including CoronaVac vaccines by Sinovac. Health care workers, along with medical clerkship students are the priority to receive the vaccine. However, the Adverse Events Following Immunization (AEFI) of the CoronaVac remains unclear. This study aims to describe and analyze the adverse events following immunization (AEFI) of COVID-19 vaccination in medical students in clerkship programs. Method We conducted a cross-sectional study using a questionnaire to assess AEFI after CoronaVac vaccination among medical clerkship students. A Chi-Square test with 95 % of CI was used to determine whether gender correlated with symptoms of AEFI. Result We identified 144 medical clerkship students. The most common AEFI of SARS-CoV-2 vaccinations was localized pain in the injection site during the first dose with 25 (45 %) reports and the booster dose with 34 (67 %) reports. Then followed by malaise, the first dose with 20 (36 %) reports and the booster dose with 21 (41 %) reports. Other symptoms like headache, fever, shivering, sleepiness, nausea, dysphagia, and cold were also reported. Conclusions CoronaVac SARS-COV-2 vaccine has several mild symptoms of AEFI and not correlated with gender. Nevertheless, follow-up after vaccination is needed to prevent immunologic responses that may occur in some patients.

Background and aim The treatment of diabetic ulcers is difficult because of defective blood vessels and frequent co-occurrence of bacterial infections. In a previous study, we found a water fraction of Merremia mammosa (Lour.) (Mm(Lour.)) had beneficial effects on wound healing in diabetic rats. This study aimed to evaluate the influence of different gelling agents added to Mm(Lour.) water fraction gel on wound healing treatment in diabetic rats. Experimental procedure Diabetic Wistar rats were divided into the following five groups: 1. positive control (Neomycin Sulfate 0.5% and Placenta Extract 10%), 2. negative control (distilled water), and 10% water fraction of Mm(Lour.) extract in 3. HPMC, 4. Carbopol, and 5. CMC Na gelling agents. The wound was made by the Morton method and treatment applied every other day for 25 days, then the wound healing process was observed. Data were observed and analysed using appropriate statistic tools. Results Histopathology observation, VEGF expression and hydroxyproline levels showed a significant acceleration of wound healing in all treatment groups compared to the negative control group. This study showed all of Mm(Lour.) gel formulations could restore the delayed healing process on wound in diabetic rats and were equally effective in accelerating wound healing. CMC Na was the most preferable because it did not irritate. Conclusion The results suggest that Mm(Lour.) water fraction in CMC Na gelling agent provided an option to be developed as a topical drug on diabetic wound healing treatment, showed by enhancement of collagen synthesis and angiogenesis.

Objective: This research aimed to evaluate the effect of fractionation of Merremia mammosa Lour. (Mm (Lour.)) extract on diabetic wound healing by observing collagen synthesis process and to search the most potent fraction.Methods: Wistar rats were divided into five groups (n=5), i.e., K-(negative control), K+ (positive control), K1 (ethyl acetate fraction), K2 (water fraction), and K3 (n-hexane fraction). The Mm (Lour.) was extracted with ethanol 70%, then fractionated by using three solvents which have different polarity. The rats were adapted in 7 days, then induced into diabetic by streptozotocin dose 40mg/kg body weight. The wound was made by Morton excision method. Treatment was given every two days and skin biopsy was done on day 11. Analysis of collagen density was done by photomicrograph of histopathology preparations in Masson’s trichome stained by using trinocular microscope with 400x magnification in 6 fields of view, then processed by imageJ software and analyzed by appropriate statistic tool.Result: The results of this research showed that fractionation of Mm (Lour.) extract significantly enhanced diabetic wound healing based on macroscopic (percentage of wound healing) and collagen density with p-value<0.05 when compared with negative control, especially the water fraction (p=0.000). The follow up post hoc analysis showed that there was no­ significant (p=0.989) or there was no meaningful difference in the group of water fraction when compared to positive control.Conclusion: Water fraction is the extract fraction of Mm (Lour.) which has the most significant influence on diabetic wound healing showed by enhancement of collagen synthesis.

Basil leaves are widely used as herbal remedies and have proven many benefits because the content of phytonutrients includes antioxidants, but at certain doses a compound retains a probability of causing toxicity in the body. This study aims to determine the acute toxicity of ethanolic extract of basil leaves seen from the value of LD50 range and renal histopathology which is the vital organ of the target of toxicity in the body. The method of acute oral toxicity test was OECD 420 fix dose procedure method with a group of 5 Balb/c female mice given a multilevel dosage. The initial dose is 2000 mg/Kg.b.w selected on a sighting study as a dose that may cause mild toxicity symptoms but does not cause death. There are 2 groups consist of treatment with dose at LD50 value and control. The result of this research showed that LD50 value of ethanol extract of Ocimum sanctum > 2000 mg/Kg.b.w. The mean renal histopathologyc scores between the control and the treatment were significantly different by The Mann-Whitney test with significance value of p=0.018. Ocimum sanctum ethanolic extract is classified as non-toxic compounds but there was a change in renal histopathology of mice in the form of focal lesions after acute exposure at highest dose of OECD 420 method.

Nutrition status in the first thousand days of life (FTDL) of 270 days during pregnancy and 730 days in the infant's first life is a critical period, since the resulting consequences are permanent and irreparable. There are still many problems in the group of FTDL around the campus of University of Jember which require intensive handling, such as stunting, low energy protein, anemia, underweight and etc. Methods of improving the quality of nutrition for the FTDL group can be done by increasing knowledge about nutrition through counseling by utilizing various media (posters, brochures, videos, demos and presentation slides). This study aims to determine how far is the effectiveness of nutrition counseling in improving knowledge and attitude awareness on nutrition problems. The method used was to give counselling on nutrition in the target groups (members of Posyandu Catleya A and B) and assessed changes by comparing the level of nutritional knowledge and attitude before and after receiving counseling. The results showed there were significant differences in the level of nutritional knowledge and attitude between before and after the counseling about nutrition and food processing technology. It can be concluded that this method is quite effective to raise awareness of FTDL group on nutrition problems. Keywords: food insecurity, nutrition counseling, nutrition awareness

Effect of analog rice’s fiber on skeletal muscles GLUT4 expression in diabetic rats Background: Disruption of glucose transportation in skeletal muscle through GLUT4 becomes a problem in diabetes. Analog rice that had been modified by adding dietary fiber could improve the expression of GLUT4.Objective: This study aims to know the effect of dietary fiber toward GLUT4 expression and to know the dietary fiber percentage in analog rice.Method: The research type is true experimental with post-test only group design. The samples consist of 24 male Wistar rats that are group into 4 groups (n=6 each group). Three groups were induced by giving a high-fat diet for 40 days and streptozotocin (STZ) 35 mg/kg BW was given at 33th day and one group was not induced. After the blood glucose level exceeded 135 mg/dl, the treatment was given. After 3 weeks, the rats were terminated and quadriceps femoris muscle tissue was taken for immunohistochemistry examination using rat GLUT4 polyclonal antibody. GLUT4 expression was quantified using an immunoreactive score (IRS-GLUT4). The data were analyzed using the Kruskal-Wallis test and Spearman test.Results: Statistical analyses showed that there were significant differences between groups with a moderate positive correlation (correlation coefficient=0,651; p=0,003).Conclusion: Dietary fiber in analog rice could improve skeletal muscle GLUT4 expression in Wistar rat diabetic model.

Electrical burns cause high mortality and morbidity and various complications, although the incidence is only 4% of all burns. Joule heating phenomenon occurs in electric burn patients which cause changes in erythrocyte morphology resulting hypercoagulability that contribute to the formation of thrombus. Changes in erythrocyte morphology may cause tissue oxygenation disorders and decrease in erythrocyte count leading to hypoxia. Until now there have been no reports of changes in erythrocyte morphology and reduction in the number of erythrocytes in burn patients due to electricity. This study aims to observe and analyze morphological and erythrocyte count in rats after electrical exposure of 140 V for 17 seconds. This is a true experimental laboratories study with post-test only control group design. The sample used were 24 rats consisting of one control group (K) and five treatment groups (P). Treatment groups were distinguished by days of blood sampling that is days 0 (P1), 3 (P2), 7 (P3), 10 (P4), and 14 (P5) post electrical exposure of 140 V for 17 seconds. Assessment in erythrocyte morphology was performed using giemsa staining that observed with 1000x magnification while erythrocyte count was performed using improved neubauer counting chamber. One Way Anova showed that there was no significant change in rats erythrocyte count after electrical exposure of 140 V for 17 seconds (p = 0.110). Descriptive analysis showed that there is morphological changes in erythrocyte morphology after electrical exposure of 140 V for 17 seconds, in terms of shape there are more fragmentosit, microsite, tear drops, stomatocytes, and cell target, in terms of size there are more microsite, and in terms of color there are more hypochromic erythrocytes.

Stunting is a condition of toddlers who have a height-for-age less than -2 SD WHO Z-score. The period from a newborn until two years is also known as the golden period. Nutrition obtained after birth affects the growth and development of them. Complementary feeding was given when they were 6 months old. The level of mother's knowledge about complementary foods has an impact on complementary feeding. Inappropriate complementary feeding can lead to stunting. The research objective was to determine the correlation between mother's knowledge about complementary feeding and the incidence of stunting in toddlers under two in Mayang. The research was an analytical observational with a cross sectional study design. The sample was 90 respondents taken using consecutive sampling method. Data collection using a questionnaire on the mother and using height-for-age data from the toddlers. Statistical test using the Spearman test, showed that there was a significant correlation between the level of mother's knowledge about complementary feeding and the incidence of stunting (p=0.024.; rho=-0.238). Due to this result, we recommend continuous health promotion and education among mothers to decrease the risk of stunting in their children.
