Background Lipedema is a chronic, incurable disorder characterized by painful fat accumulation in the extremities. While the application of liposuction in lipedema management has become increasingly popular, the safety and effectiveness of this approach remain contentious. Our systematic review and meta-analysis aimed to assess various liposuction modalities in lipedema management to verify their safety and efficacy. Methods In-line with the Preferred Reporting Items for Systematic Reviews and Metaanalyses guidelines, we performed a comprehensive literature review from inception untilMarch 2023 using the following electronic databases: CENTRAL,MEDLINE, Google Scholar, and EMBASE. Results From the 562 initially identified articles, 20 met our inclusion/exclusion criteria for evaluation. Our review encompassed 14 prospective cohort studies, 3 retrospective studies, 2 case series, and 1 cross-sectional study. Ameta-analysis of nine articles revealed a notable improvement in the quality of life, pain, pressure sensitivity, bruising, cosmetic impairment, heaviness, walking difficulty, and itching among lipedema patients who underwent liposuction. Although complications such as inflammation, thrombosis, seroma, hematoma, and lymphedema-related skin changes were reported, severe complications were rare. Crucially, no instances of shock, recurrence, or mortality were reported.

The desire of modern people to maintain a healthy and beautiful appearance is increasing day by day along with the increasing interest in skin health and the demand for functional cosmetics. Accordingly, research on functional cosmetic materials with few side effects and excellent efficacy is being actively conducted. Therefore, this study tried to verify the antioxidant and whitening effects of the mixed extracts of Bixa orellana, Ammi majus, and Glycyrrhiza glabra, whose efficacy has been individually verified. Extracts (BAG-1~4) with different extraction methods such as steaming, fermentation, and ultrasonication were prepared for 3 types of natural plants, and antioxidant and whitening effects of these extracts were confirmed. For this purpose, antioxidant, tyrosinase activity, melanin production and stability experiments were conducted. Extracts (BAG-1~4) had no cytotoxicity, and antioxidant and whitening effects were confirmed. BAG-4 extracted by steaming and fermentation showed the best efficacy. It seems that enzymes such as lipase, protease, and amylase increase phenol components by various yeasts involved in the fermentation process, thereby improving antioxidant and melanin production inhibitory effects. It was confirmed that the three types of natural plant extracts could be used as safe and functional cosmetic materials.

This study was conducted to investigate effect of complex extract of various mushrooms and sharp toothed eel on the skin conditions with atopic dermatitis and acne symptoms. The total phenol concentration was increased in order of hot water> ethanol> ethyl acetate> petroleum ether> chloroform extract. Especially, when the hot water extract was used, it was about 2-3 fold higher than that of ethyl acetate, petroleumether, and chloroform extract. When the complex extract concentration was increased from 1.0 to 50 mg/L, the DPPH scavenging rate increased from 10.1 to 81.4%. The reduction power was sharply increased from 0.05 to 0.27 (700 nm) when the complex extract concentration was increased from 25 to 75 mg/L. However, above 100 mg/L, it was not decreased. In the case of SOD-like activity, it was 45.7% at 100 mg/L. Total numbers of patients with atopic dermatitis were 15 and 5 patients with severe acne symptoms. According to photos taken before and after the treatment and questionnaire results, considerable improvements in skin conditions are observed in the patients with atopic dermatitis and acne. For atopic patients, erythema and edema have been improved but the degree of effect was dependent on the individual's constitution. Concerning acne, the effect of coating of the extracts was prominent for first week and the degree decreased with time till 4 weeks. The complex extracts wereefficient in soothing rash and maturation. Side effects such as a scar were not detected during the application and treatment.

The present study was conducted to identify the factors related to the hypertension, and to offer the evidence of 1st prevention of hypertension. 2,230 male workers aged 30-59 years were observed the relationships between hypertension and age, BMI, glucose intolerance, smoking, alcohol drinking, regular exercise, eating habits using data from health check-ups in 2011. As a results, the incidence rate of hypertension was 18.8% of 30-39 year old group, 23.8% of 40-49 year old group, 33.0% of 40-49 year old group. The incidence rate of hypertension was significantly higher as age and BMI ascend, and it was higher in the group of abnormal glucose intolerance, regular alcohol intake, no regular exercise than their respective counterparts. The multivariable-adjusted odds ratio of hypertension increased significantly as there is an increase in age, and the group of abnormal glucose intolerance, smoking, regular alcohol intake, no regular exercise. In conclusion, obesity, glucose intolerance, alcohol intake, and physical inactivity are risk factors for hypertension, therefore we need the control of these factors for 1st prevention of hypertension.

Objectives: Exposure to airborne bacteria is associated with adverse health effects such as respiratory and infectious diseases. This study evaluated airborne bacterial concentrations in the living rooms, kitchens, and toilets of 30 homes. Methods: Bacteria were sampled with an MAS100 impactor in three spaces in the subject homes between April 2014 and February 2015. Bacteria were grown on TSA plates for 48 hours at $35^{\circ}C$. The bacterial strains were isolated and amplified by polymerase chain reaction. Results: The most culturable bacteria were found in toilets ($624.0CFU/m^3$, GM: $417.3CFU/m^3$), followed by in the kitchen ($503.8CFU/m^3$, GM: $324.9CFU/m^3$). The dominant genera identified were: Staphylococcus sp.(19%), Micrococcus sp.(16%), and Bacillus sp.(11%) in the indoor air and Bacillus sp. (30%) in the outdoor air. Gram-positive bacteria comprised more than half of all colonies. Conclusion: In this study, culturable bacteria concentrations were higher than those reported in other spaces. Therefore, it is important to control relative humidity and remove moisture to prevent bacteria from multiplying. Additionally, the dominant species in indoor air were Staphylococcus sp. and Micrococcus sp. These are found on the human skin, mucous membranes, and hair, so human activity can affect bacterial distribution. Therefore, cleaning and controlling moisture are important for reducing indoor bacterial concentrations.

Purpose: A high level of air pollutants can increase the number of patients with allergy-related diseases such as asthma and allergic rhinitis (AR). To analyze the association between air pollution and allergic disease, we investigated 2 areas in Korea: Incheon, an industrial area, and Jeju, a non-industrialized area. Methods: Second grade students at elementary schools (11 schools in Incheon and 45 schools in Jeju) were examined in a cross-sectional study. A questionnaire was used and a skin prick test was performed. The levels of $NO_2$, $CO_2$, $O_3$, particulate matter (PM) $PM_{10/2.5}$, formaldehyde, tVOCs, and dust mites in the classrooms and grounds were determined. Results: The levels of outdoor CO, $PM_{10}$, and $PM_{2.5}$ were significantly higher in Incheon (P<0.01). The levels of indoor CO, $CO_2$, $PM_{10}$, $PM_{2.5}$ were significantly higher in Incheon (P<0.01). The prevalence rates of AR symptoms at any time, AR symptoms during the last 12 months, diagnosis of rhinitis at any time, and AR treatment during the last 12 months were significantly higher in Incheon (P<0.01). The prevalence rate of wheezing or whistling at any time, and wheezing during the last 12 months were significantly higher in Incheon (P<0.01). Conclusion: We found that the children living in Incheon, which was more polluted than Jeju, had a higher rate of AR and asthma symptoms compared to children in Jeju. To determine the effect of air pollution on the development of the AR and asthma, further studies are needed.

This study was performed to investigate the effects of very low calorie diet (VLCD) using newly meal replacements that contain the wild grass extracts based on Samul-tang ingredients on weight reduction and health in the obese adult women ($BMI{\geq}25\;kg/^2$) for four weeks. Seventy five women participated in this experiment. Subjects were randomly classified three groups: 1) General Diet group (GD group, n=25) consumed 3 regular meals within 600 kcal/day, 2) Meal replacements group (MR group, n=25) consumed 1 regular meal and 2 meal replacements within 600 kcal/day, 3) Herbal Meal replacements group (HMR group, n=25) consumed 1 regular meal and 2 meal replacements within 600 kcal/day. Anthropometric measurements, body composition, biochemical measurements and body symptoms were assessed before (the initial) and after (the 4th week) the study. Anthropometry measurements such as weight, waist and hip circumference, and BMI and body composition such as body fat percent, fat mass significantly decreased in all groups after diet intervention. Anthropometric measurements and body composition of the ]lim group significantly decreased more than those of GD and MR groups. Serum Total cholesterol was significantly decreased in all groups. However, there was no significant difference among three groups during the experimental period. HMR group had significantly less felt a pain than GD and MR groups in body symptoms such as anemia, powerlessness, vomiting, constipation and dryness of skin during the experimental period. Therefore, very low calorie diet (VLCD) using meal replacements that contain the wild grass extracts based on Samul-tang ingredients was very effective on weight reduction and health in the obese adult women.
