BackgroundLactobacillus gasseri BNR17 is a type of probiotic strain isolated from human breast milk. A study was reported regarding the fact that BNR17 was an inhibitor of obesity and diabetic activities in the human body through previous animal experiments. This study was furthered to investigate the effect of BNR17, a probiotic strain isolated from human breast milk, on obese and overweight adults.MethodsSixty-two obese volunteers aged 19 to 60 with body mass index ≥ 23 kg/m2 and fasting blood sugar ≥ 100 mg/dL participated in a placebo controlled, randomized, and double-blind trial. For 12 weeks, 57 participants were given either placebo or BNR17 and were tested by measuring body fat, body weight, various biochemical parameters, vital signs, and computed tomography at the start of the study and at weeks 4, 8, and 12. The subjects assumed usual daily activities without having to make behavioral or dietary modifications during the course of the study.ResultsAt the 12th week, a slight reduction in body weight was noted in the BNR17 group, but there were no significant weight changes between groups. Decrease of waist and hip circumferences in the BNR17 group was more pronounced than those in the placebo group. The two groups had no special or severe adverse reactions.ConclusionDespite there being no change in behavior or diet, administration of only the supplement of BNR17 reduced weight and waist and hip circumference. However, there were no significant differences between the two groups. These findings warrant a subsequent longer-term prospective clinical investigation with a large population.
This study was conducted to evaluate whether the composition of carbohydrate or fat diet affects insulin resistance by measuring the muscle glucose transport rate. Both high-sucrose and high-starch diet with or without high-fat decreased insulin-stimulated glucose transport, but there were no significant differences among groups. Calorie intake in both high-sucrose and high-starch diet groups was higher than in chow group. The high-fat high-sucrose diet induced decrease in insulin-stimulated glucose transport was partially improved by supplement with fish oil. Calorie intake in high-fat high-sucrose and fish oil supplemented groups was higher than in chow group. The decreased insulin-stimulated glucose transport was accompanied by the increase in visceral fat mass, plasma triglyceride and insulin levels. These changes were improved by the supplement with fish oil. These results demonstrate that the composition of fat in diet is clearly instrumental in the induction of muscle insulin resistance. However, in high carbohydrate diet, it is likely that the amount of calorie intake may be a more important factor in causing insulin resistance than the composition of carbohydrate. Thus, the compositions of carbohydrate and fat in diet differentially affect on muscle insulin resistance.
These results suggest that KRG extract may be an effective and safe alternative treatment for children with inattention and hyperactivity/impulsivity symptoms. Further studies to investigate the efficacy and safety of KRG are warranted.
This review presents information on changes in the accreditation standards of medical schools in Korea by the Korean Institute of Medical Education and Evaluation (KIMEE) from 2000 to 2019. Specifically, the following aspects are explained: the development process, setting principles and directions, evaluation items, characteristics of the standards, and validity testing over the course of 4 cycles. The first cycle of accreditation (2000–2005) focused on ensuring the minimum requirements for the educational environment. The evaluation criteria emphasized the core elements of medical education, including facilities and human resources. The second cycle of accreditation (2007–2010) emphasized universities’ commitment to social accountability and the pursuit of excellence in medical education. It raised the importance of qualitative standards for judging the content and quality of education. In the post-second accreditation cycle (2012–2018) which means third accreditation cycle, accreditation criteria were developed to standardize the educational environment and programs and to be used for curriculum development in order to continually improve the quality of basic medical education. Most recently, the ASK 2019 (Accreditation Standards of KIMEE 2019) accreditation cycle focused on qualitative evaluations in accordance with the World Federation of Medical Education’s accreditation criteria to reach the international level of basic medical education, which emphasizes the need for a student-centered curriculum, communication with society, and evaluation through a comprehensive basic medical education course. The KIMEE has developed a basic medical education evaluation and accreditation system in a step-by-step manner, as outlined above. Understanding previous processes will be helpful for the future development of accreditation criteria for medical schools in Korea.
Compliance with the lipid-lowering therapy was relatively low and several factors for non-compliance were detected.
We are currently experiencing the disaster of the COVID-19 pandemic. Since the first case of Coronavirus disease 2019 (COVID-19) was confirmed in South Korea on January 20, the number of COVID-19 cases in South Korea has been rapidly increasing until early March due to a local spread in Daegu, which is one of the eight metropolitan cities in South Korea with a population of 2.5 million. As the medical academy has social accountability as professionals, Daegu-Gyeongbuk branch of the Korean Academy of Family Medicine (Daegu-Gyeongbuk branch) developed the health counseling program for discharged COVID-19 patients. The Daegu-Gyeongbuk branch communicated with Daegu Medical Association and Daegu city for this program and incorporated available resources and capabilities as a leader of this program. This newly developed counseling program consists of medical consultations, sending healthcare brochures and medical supplies, and the appraisal at the end of the program. Not only COVID-19 related symptoms but also other psychological problems are also dealt with during consultations. This program started on March 18, and over 1,700 recovered patients have been receiving counseling as of April 28. Communication and cooperation between the medical academy, medical association, and government are essential to overcome the COVID-19 pandemic. Besides, we expect to apply this health counseling program and our model of setting this program cooperating with medical association and government to different infectious pandemic crisis.
Background: Smartphone addiction, academic stress and anxiety of university students are increasing gradually; however, few studies have investigated these factors in medical school students. Therefore, this study investigated associations between smartphone addiction scale and sociopsychological aspects in medical school students. Methods: A total of 231 Yeungnam University College of Medicine students were enrolled in this study in March 2017. Gender, school grade, type of residence, and smartphone usage patterns of the students were surveyed. The Korean Smartphone Addiction Proneness Scale and each Korean version scale were used to assess sociopsychological aspects such as loneliness, stress and anxiety. Results: There was a direct statistical correlation between loneliness, stress of negative perception, anxiety and smartphone addiction scales. There was also a negative statistical correlation between stress of positive perception and smartphone addiction scales. There was a higher level of anxiety among female students than male students. Additionally, there was a higher level of stress associated with negative perception and anxiety among medical students in the first grade than other students. Moreover there was a higher level of loneliness, stress of negative perception and anxiety among students who live with friends than students who live with their own family. Conclusion: Smartphone addiction scale and sociopsychological aspects significantly correlated. Moreover, the results suggest that female medical students in the first grade who have been separated from their family need more attention and management of loneliness, stress and anxiety to avoid smartphone addiction.
Background: The prevalence of metabolic syndrome is increasing in Korea. The aim of this study was to establish if there is an association between the presence of metabolic syndrome and the development of gallbladder stones in Koreans. Methods: Among the subjects who visited a health promotion center of a general hospital from January 2001 to December 2005, a total of 34,574 adults was examined. Among them, the fi nal 34,470 adults (males 20,277, females 14,193) were included. Metabolic syndrome was defi ned if they fell under the three conditions of BMI ≥ 25 kg/m 2 , blood pressure ≥ 130/85 mmHg, fasting glucose 110 mg/dL, triglyceride ≥ 150 mmHg and low HDL-cholesterol (< 40 mg/dL in men, < 50 mg/dL in women). After adjusting for age and sex, logistic regression analysis was done to evaluate the relationship between metabolic syndrome and gallstones. Results: This study showed that the prevalence of metabolic syndrome was 17.6% (males 21.1%, females 12.4%). Gallbladder stone risk was increased according to BMI, high blood pressure, high fasting blood glucose and low HDL. Gallbladder stone risk was increased according to clustering of components of metabolic syndrome after adjustment for age and sex (1 criterion:
