Hightlight:The effect of orlistat on glycemic control and weight loss in overweight or obese type 2 diabetes mellitus patients was determinedHbA1c and FPG level in overweight and obese type 2 diabetes mellitus patient can improved by orlistat as an adjuvant therapy. Abstract:Risk of Type 2 diabetes mellitus (T2DM) increases steadily with increasing overweight and obesity, and these two-health problems are emerging epidemics worldwide. Orlistat, a lipase inhibitor for weight loss drug, is often used in T2DM medication as adjuvant therapy, but effectiveness of the drug for improving glycemic control on T2DM patients is unclear. This study was to determine the effect of orlistat on glycemic control and weight loss in overweight or obese patients with T2DM. Term “Orlistat” AND “(obesity OR overweight)” AND “(HbA1c OR A1C)” AND “diabetes” were systematically searched in Pubmed and Science Direct web databases up to March 2021. Only randomized controlled study (RCT) methods studies were included in this study. Collected final samples were presented in a table with narrative review. There were 9 RCT studies with a total 2,175 subjects that met inclusion criteria. Of the sample, 360 mg/day orlistat as an adjuvant therapy, was administered to overweight or obese T2DM patients together with hypocaloric intake (8 studies) or without hypocaloric intake (1 study) intervention. They were examined for 12-52 weeks. From 2 short-term (12 weeks) studies, one study revealed that orlistat improved HbA1c and fasting plasma glucose (FPG) level significantly, while one study showed no significant effect compared to placebo. Seven other studies (long term observation) had found that orlistat significantly improved HbA1c and FPG level. All studies found that orlistat significantly reduced body weight. As an adjuvant therapy, Orlistat improved HbA1c and FPG level in overweight and obese T2DM patients.

Code switching is an intriguing phenomenon to investigate because it is a part of the development process and the use of multiple languages (bilingual). In the world of education, both at the middle and upper levels, the use of code switching can be done by teachers or students in the classroom. This research was conducted to find out the factors causing teachers to do code switching in the classroom. The research method applied in this study was qualitative research in the form of a case study. The writers selected the participants for this research by using a convenience sampling technique. There were two teachers of English at SMA Negeri 15 Palembang, and those teachers were selected as the participants to collect the data. In collecting data, the writers used interviews through open-ended questions. Then, the writers analyzed the data obtained from the interview using a theme code system in the form of table codes, synchronizing the data with the aspects and items that prevailed in the interview protocol. The result of this research based on the interviews showed that there are two factors causing teachers to do code switching. Two factors are linguistics and non-linguistics. Language linguistics factors are divided into language stagnation and a lack of students’ knowledge of vocabulary. Furthermore, non-linguistical factors are divided into the emotional condition of the teacher and the condition of the class situation.
