Introduction: Retinopathy of prematurity is a potentially blinding disease of the eye due to abnormal retinal vascularization. Gestational age, preterm birth, oxygen therapy, and RBC transfusion are some of the factors associated with ROP. Purpose: This study aims to determine the relation between gestational age, birth weight, duration of oxygen therapy, and RBC transfusion with ROP. Methods: This research is a case-control study using medical records data from Dr. Soetomo General Hospital in the period of January -June 2019. Data is analyzed using logistic regression analysis in SPSS v. 25. Results: The case group consists of 22 patients with ROP while the control group consists of 66 patients without ROP. Gestational age (p=0.030; OR=3.10, 95% CI 1.113-8.606) and duration of oxygen therapy (p=0.012; OR=3.75, 95% CI 1.342-10.481) shows a statistically significant relation with ROP. There is no relation between birth weight (p=0.098; OR= 2.30, 95% CI 0.857-6.171) and RBC transfusion (p=0.881; OR=1.09; 95% CI 0.343-3.480) with ROP. Conclusions: There is a relation between gestational age and duration of oxygen therapy with ROP. Meanwhile, birth weight and RBC transfusion have no relation with ROP.

The COVID-19 pandemic has forced a lot of people, including Indonesian citizens to face various changes, adapt to the current situation, and implement new lifestyle habits. Measures have been taken to minimize the risk of COVID-19 transmission, such as implementing the health protocols which include washing hands, wearing masks, social distancing, avoiding crowds, and minimizing mobility. Furthermore, maintaining and increasing the body's immune system is crucial as an effort to prevent COVID-19 infection. One of the ways to increase the body's immune system is through a balanced diet and consuming nutritious food. Therefore, this research was conducted to analyze the community's comprehension about nutrition during the pandemic. This research was a descriptive analytic study. The data was collected twice, prior to-and following the intervention, using google form which contained several questions regarding nutritional knowledge. The number of participants which fulfilled the inclusion criteria includes 53 people aged 18-35 years old. There was a significant difference between the average knowledge related to the results of community knowledge before (46.25) and after (56.47) providing education (p= 0.001) where there was an increase of 22.1%. Education given through online webinar SEROTONIN 2021, improved the community's knowledge about nutritional health during the COVID-19 pandemic, especially in productive age.
