OBJECTIVE: Currently, human immunodeficiency virus (HIV) and multi-drug resistant tuberculosis (MDR-TB) without extensive drug resistance (XDR) are significant challenges in terms of the global burden of disease. This study aimed to evaluate the trends of the global burden of MDR-TB without XDR and HIV/AIDS-MDR-TB without XDR, focusing on differences in socioeconomic status and sex for 204 countries and territories across periods from 1990 to 2019. MATERIALS AND METHODS: D ata from t he Global Burden of Disease (GBD) 2019 study were obtained to construct a separate index measuring the burden of MDR-TB without XDR and HIV/AIDS-MDR-TB without XDR. Incidence, preva-lence, mortality, and disability-adjusted life years (DALYs) were calculated for each case and group. A population-attributable fraction approach was used to assess mortality and incidence of HIV/AIDS and MDR-TB coinfection. 95% uncertainty intervals (UIs) were presented for all measures. RESULTS: Our global estimates suggest that there were approximately 450,000 (95% UI 247,000-785,000) incident cases of MDRTB without XDR and 109,000 (43,000-210,000) deaths caused by MDR-TB without XDR among individuals who were HIV-negative in 2019. For HIV-positive individuals, the corresponding figures were approximately 47,000 (33,000-67,000) incident cases of MDR-TB and 19,000 (8,000-36,000) deaths due to MDR-TB in the same year. In 2019, higher numbers of incident cases and deaths were observed in males compared to females among individuals who were HIV-negative. Conversely, for HIV-positive individuals, females had higher numbers of incident cases and deaths compared to males. Specifically, the estimated numbers for incident cases were 23,000 (15,000-33,000) for females and 24,000 (17,000-35,000) for males, while the estimated numbers for deaths were 9,600 (4,000-17,900) for females and 9,800 (4,100-18,500) for males. Male-to-female ratios have remained above 1.0 from 1990 to 2019 in both incident cases and number of deaths for HIV-negative individuals. However, for HIV and MDR-TB coinfection, both ratios were below 1.0 in most of the time series. CONCLUSIONS: Males had more cases and deaths due to MDR-TB without XDR than females in HIV-negative patients, while females faced a higher incidence and mortality in HIV/AIDS-MDR-TB without XDR. Interventions are needed to deal with such factors, which increase the burden of coinfection among females across the world. [ABSTRACT FROM AUTHOR]

OBJECTIVE: This study aimed to define a method of classifying patients with mild cognitive impairment caused by Alzheimer’s disease by the retrieval of functional near-infrared spectroscopy (fNIRS) signal characteristics obtained during olfactory stimulation and the validation of deep learning findings. PATIENTS AND METHODS: Participants were recruited for the study from March 02 and August 30, 2021. A total of 78 participants met the criteria for categorization. The Mini-Mental State Examination and the Seoul Neuropsychological Scale were used to distinguish between patients with mild Alzheimer’s disease-related cognitive impairment and healthy controls. fNIRS data received during olfactory stimulation were used to create 1,680 time-series sample values. A total of 150 indices with a p-value ≤ 0.1 were used as deep learning features to construct the result values for 120 models accounting for all conceivable combinations of data ratios. RESULTS: For this trial, 78 participants were recruited for the original intervention trial. The average accuracy of the 120 deep-learning models for classifying patients with Alzheimer’s-related mild cognitive impairment ranged from 0.78 to 0.90. Sensitivity ranged from 0.88 to 0.96 for the 120 models, while specificity ranged from 0.86 to 0.94. The F1 scores ranged from 0.74 to 0.88. At 0.78 to 0.90, the precision and recall were equivalent. CONCLUSIONS: This trial using a deep-learning model found that the representative value extracted from the time series data of each channel could distinguish between healthy people and patients with mild cognitive impairment caused by Alzheimer’s disease.

OBJECTIVE: The ethnic and sex differences in the distributions of body mass index (BMI) and waist circumference (WC) among adults are largely unknown. Therefore, we aimed to investigate the percentiles of BMI and WC in groups divided according to age, sex, and ethnicity. PATIENTS AND METHODS: We conducted a population-based binational study of adults aged =20 years based on data from two sources: US National Health and Nutrition Examination Survey (2015 to 2020) and Korea National Health and Nutrition Examination Survey (2016 to 2019). RESULTS: Weight, height, and WC were measured in 13,144 American adults and 30,191 Korean adults. Overall, BMI increased at younger ages and decreased at older ages, which indicates a reversed U-shaped relationship, and differed in terms of age, sex, and ethnicity. Women in the other Hispanic, non-Hispanic white, non-Hispanic black, and "other ethnic groups" showed a common BMI peak at ages 50-54 years. The patterns of WC distribution were similar to those of BMI distribution. CONCLUSIONS: In this binational representative study, we found varied distributions of ethnic and sex differences in BMI and WC. Considering the differences in these distributions may help improve individual and personalized treatment strategies. [ABSTRACT FROM AUTHOR]

OBJECTIVE: There is a lack of pediatric studies that have analyzed trends in mean body mass index (BMI) and the prevalence of obesity and overweight over a period that includes the mid-stage of the COVID-19 pandemic. Thus, we aimed to investigate trends in BMI, overweight, and obesity among Korean adolescents from 2005 to 2021, including the COVID-19 pandemic. SUBJECTS AND METHODS: We used data from the Korea Youth Risk Behavior Web-based Survey (KYRBS), which is nationally representative of South Korea. The study included middleand high-school students between the ages of 12 and 18. We examined trends in mean BMI and prevalence of obesity and/or overweight during the COVID-19 pandemic and compared these to those of pre-pandemic trends in each subgroup by gender, grade, and residential region. RESULTS: Data from 1,111,300 adolescents (mean age: 15.04 years) were analyzed. The estimated weighted mean BMI was 20.48 kg/m2 (95% CI, 20.46-20.51) between 2005 and 2007, and this was 21.61 kg/m2 (95% CI, 21.54-21.68) in 2021. The prevalence of overweight and obesity was 13.1% (95% CI, 12.9-13.3%) between 2005 and 2007 and 23.4% (95% CI, 22.8-24.0%) in 2021. The mean BMI and prevalence of obesity and overweight have gradually increased over the past 17 years; however, the extent of change in mean BMI and in the prevalence of obesity and overweight during the pandemic was distinctly less than before. The 17-year trends in the mean BMI, obesity, and overweight exhibited a considerable rise from 2005 to 2021; however, the slope during the COVID-19 pandemic (2020-2021) was significantly less prominent than in the pre-pandemic (2005-2019). CONCLUSIONS: These findings enable us to comprehend long-term trends in the mean BMI of Korean adolescents and further emphasize the need for practical prevention measures against youth obesity and overweight.

After administering cultivated wild ginseng pharmacopuncture (CWGP) to advanced cancer patients, the response and survival rate were evaluated. This prospective observational pilot study of CWGP was conducted at the East-West Cancer Center of Daejeon University, Dunsan Oriental Hospital from August 2007 to June 2008. Seven patients were recruited for this study. One cycle of treatment consisted of intravenous infusion of CWGP (20 mL/day) for 2 weeks with an expected treatment duration of four cycles (60 days, 2 months). Blood tests were conducted every cycle and computed tomography was performed every second cycle as follow-up. Overall survival was measured from initial administration of CWGP to death. We used the international standards provided by the Response Evaluation Criteria in Solid Tumors for measuring response rate and Kaplan-Meier analysis to determine statistical significance. Seven patients received a total of 55 cycles (1 with 1 cycle, 2 with 2 cycles, 1 with 3 cycles, 2 with 13 cycles, 1 with 20 cycles). One-year survival rate was 57.1%, and the median survival time was 544 days. Among these patients, two non-small cell lung carcinoma patients and one advanced gastric adenocarcinoma patient showed stable disease. Two patients dropped out after the first and second cycles of treatment without receiving a new computed tomography scan. Two patients showed progressive disease. Although a further large scale study is necessary, CWGP showed potential as an effective treatment for two non-small cell lung carcinoma patients and one advanced gastric carcinoma patient.
