Patients with diabetes in regions with population decline and likelihood of receiving diabetes management education and screenings for related complications in Korea.

OBJECTIVE: Many municipal districts in Korea face population decline owing to overall population decreases and aging. We investigated the association between geographic rurality and likelihood of receiving diabetes management education and diabetic retinopathy and diabetes-related kidney disease screenings among adults with diabetes. METHODS: Patient data were obtained from the 2021 Korea Community Health Survey (27,391 individuals; aged ≥19 years and physician-diagnosed with diabetes mellitus). Geographic rurality was categorized based on population decline as follows: with, at risk of, or without population decline. The association between geographic rurality and likelihood of receiving diabetes management education and diabetic retinopathy and diabetes-related kidney disease screenings was examined using multilevel logistic regression analyses. RESULTS: Among 27,391 patients with diabetes, 31.1% received diabetes education; 40.0% and 46.4% were screened for diabetic retinopathy and diabetes-related kidney disease, respectively. Individuals residing in regions with population decline were less likely to receive diabetes education (odds ratio [OR] 0.62, 95% CI 0.50-0.75) and diabetic retinopathy (OR 0.79, 95% CI 0.70-0.90) and diabetes-related kidney disease (OR 0.64, 95% CI 0.55-0.75) screenings, as compared with their counterparts. CONCLUSIONS: Our findings highlight the importance of increased monitoring and providing diabetes education and screenings for patients with diabetes living in rural areas.

Five-year Trajectory about Screening for Complication of Diabetes Kidney Disease and Cardiovascular Disease Mortality : Focusing on Regional Difference.

BACKGROUNDS: The overall screening rate for complication of diabetes kidney disease is improving; however, regional variations are increasing. It is necessary to select regions vulnerable to change and understand their characteristics. METHODS: Group-based trajectory analysis was performed to derive change patterns in the complication of diabetes kidney disease screening rate in 244 regions using Community Health Survey data between 2015 and 2019. ANOVA test was conducted to examine the differences in regional characteristics and CVD in each change pattern. RESULTS: The change patterns in complication of diabetes kidney disease screening rate were classified into four groups: high and rapidly increasing (Group 1, 5.2%), steady high (Group 2, 8.2%), moderate and increasing (Group 3, 52.9%), and low and slightly increasing (Group 4, 23.8%). Group 4 had many rural areas and worse socioeconomic status, healthcare systems, health behaviors, and diabetes management, and these regions had higher CVD mortality rates. CONCLUSIONS: Regions where the screening for complication of diabetes kidney disease rate did not improve compared to other regions were vulnerable not only in socioeconomic status, healthcare system, and health behavior, but also in disease management. This suggests the need for local and environmental support, as well as aggressive health service interventions in relatively vulnerable areas.

Satisfaction with local healthcare services and medical need among hypertensive patients: a nationwide study.

BACKGROUND: Investigating the factors associated with unmet medical needs is important since it can reflect access to healthcare. This study examined the relationship between the unmet medical needs of patients with hypertension and their satisfaction with the healthcare services available in their neighborhoods. METHODS: Data were from the 2021 Korean Community Health Survey. The sample included individuals aged 19 years who were diagnosed with hypertension. The main outcome measure was unmet medical need. The relationship between the outcome measure and independent variables were analyzed using multivariate logistic regressions, along with a subgroup analysis based on whether patients were currently receiving treatment for hypertension. RESULTS: Unmet medical needs were found in 4.3% of the study participants. A higher likelihood of unmet medical needs was found in individuals not satisfied with the healthcare services at proximity (adjusted OR = 1.69, 95% CI: 1.49-1.92) compared to those satisfied with services nearby. Similar tendencies were found regardless of whether individuals were currently receiving treatment for hypertension, although larger differences were found between groups in participants who were currently not receiving treatment. CONCLUSIONS: The findings infer the need to consider patient satisfaction with nearby healthcare services in implementing public health policies that address unmet medical need in patients with hypertension.

Association between residing in municipalities facing population decline and satisfaction with neighboring healthcare infrastructure in older aged adults.

BACKGROUND: Many municipalities in rural areas of Korea are facing population decline due to the aging population phenomenon. This study examined the relationship between residing in municipalities facing population decline and satisfaction with nearby healthcare infrastructure in older aged adults. METHODS: The 2021 Korea Community Health Survey (KCHS) data were used. Municipalities were classified as those not facing population decline, those at risk, and those facing population decline based on the Population Decline Index. The association between residing in municipalities facing population decline and satisfaction with nearby healthcare infrastructure was examined cross-sectionally using a multi-level logistic regression analysis. Satisfaction with available public transportation was concomitantly examined as it is related to accessing healthcare services. RESULTS: Of the 58,568 individuals aged 65 years or above analyzed, 27,471 (46.9%) adults were residing in municipalities without population decline, 4,640 (7.9%) adults in municipalities at risk of population decline, and 26,457 (45.2%) in municipalities with population decline. Individuals living in municipalities with population decline were more likely to be dissatisfied with nearby healthcare infrastructure (OR 1.76, 95% CI 1.41-2.20). Similar tendencies were found for public transportation infrastructure (OR 1.67, 95% CI 1.38-2.03). CONCLUSIONS: Individuals residing in municipalities with declining populations are more likely to report dissatisfaction with nearby healthcare infrastructure and public transportation. These findings emphasize the importance of providing adequate medical infrastructure to reduce potential health-related disparities.

Mental health effects associated with COVID-19 financial assistance in South Korea: a comparison of employment status.

BACKGROUND: COVID-19 has created tensions across different sectors of the society, but the impact has been unequal. Vulnerable people have been most affected, especially those with insecure employment and who have experienced economic hardships due to unemployment and lost wages. The combination of social change and economic hardships due to the pandemic increases the risk of poor mental health. Some countries have utilized financial assistance to alleviate economic hardships caused by COVID-19, and in South Korea, the central and local governments have implemented COVID-19 financial assistance. This study analysed the impact of financial assistance on mental health associated with working status during the COVID-19 pandemic in South Korea. METHODS: The participants of this study were randomly selected from residents of Gyeonggi-do after being proportionally allocated by resident registration population status. A total of 1,000 adult males and females aged 19 years or older in Gyeonggi-do who received financial assistance from the central and local governments were selected. A retrospective pre-post-study design was applied, and mental health surveys including the Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder 7-item scale (GAD-7) were applied. RESULTS: The results show that depression scores averaged 5.5 and anxiety scores averaged 4.4 before COVID-19 Financial Assistance. It is similar to the national average of 5.1 and 4.5 respectively at that time. After the assistance, depression scores dropped to 4.5, and anxiety scores dropped to 3.2. Before the assistance, depression and anxiety were higher among temporary day labourers with less job security, and they showed the most significant improvement in mental health. For full-time workers, there was no significant change in anxiety or depression after receiving the assistance. CONCLUSIONS: Financial assistance can provide material resources and also positively affect mental health. In particular, it had a greater impact on the relatively vulnerable groups, such as those in unstable employment.

The Combined Effects of Alcohol Consumption and Smoking on Cancer Risk by Exposure Level: A Systematic Review and Meta-Analysis.

BACKGROUND: Alcohol consumption is a major risk factor for cancer, and when combined with smoking, the risk increases. Nevertheless, few studies have comprehensively evaluated the combined effects of alcohol consumption and smoking on the risk of various cancer types. Therefore, to assess these effects, we conducted a systematic review and meta-analysis. METHODS: We performed a systematic search of five literature databases, focusing on cohort and case-control studies. Considering exposure levels, we quantified the combined effects of alcohol consumption and smoking on cancer risk and assessed multiplicative interaction effects. RESULTS: Of 4,452 studies identified, 24 (4 cohort studies and 20 case-control studies) were included in the meta-analysis. We detected interaction effect of light alcohol and moderate smoking on head and neck cancer risk (relative risk [RR], 4.26; 95% confidence interval [CI], 2.50-7.26; I² = 65%). A synergistic interaction was observed in heavy alcohol and heavy smoking group (RR, 35.24; 95% CI, 23.17-53.58; I² = 69%). In more detailed cancer types, the interaction effect of heavy alcohol and heavy smoking was noticeable on oral (RR, 36.42; 95% CI, 24.62-53.87; I² = 46%) and laryngeal (RR, 38.75; 95% CI, 19.25-78.01; I² = 69%) cancer risk. CONCLUSION: Our study provided a comprehensive summary of the combined effects of alcohol consumption and smoking on cancers. As their consumption increased, the synergy effect became more pronounced, and the synergy effect was evident especially for head and neck cancer. These findings provide additional evidence for the combined effect of alcohol and smoking in alcohol guidelines for cancer prevention.

Area-level deprivation and handwashing behavior during the COVID-19 pandemic: A multilevel analysis on a nationwide survey in Korea.

This study investigated the association between area deprivation level and performance of handwashing behavior during the COVID-19 pandemic in Korean adults. This study used data from the 2015 Population and Housing Census data to measure area deprivation level. The 2020 Korea Community Health Survey was used for all other variables, including hand hygiene behavior (August through November 2020). The association between area deprivation level and practice of handwashing behavior was examined using multilevel logistic regression analysis. The study population comprised 215,676 adults aged 19 years or above. Compared to the least area deprived group, the most deprived group was more likely to not wash hands after using the restroom (OR 1.43, 95% CI 1.13-1.82), after coming home (OR 1.85, 95% CI 1.43-2.39), and using soap (OR 1.55, 95% CI 1.29-1.84). The findings suggest the importance of considering area deprivation in implementing policies that promote handwashing, particularly during a pandemic.

Is fear of COVID-19 higher in individuals residing in more deprived areas? A nationwide study.

BACKGROUND: This study investigated the association between various types of coronavirus disease 2019 (COVID-19)-related fear and the level of area deprivation in Korea. METHODS: Different types of COVID-19-related fear were examined, namely fear of infection, fear of dying from infection, fear of public criticism, fear of a family member getting infected and fear of economic loss. The level of area deprivation was measured based on the Area Deprivation Index, which was calculated based on population census data. The association between various types of COVID-19-related fear and the level of area deprivation was analyzed using multivariable logistic regression analysis. RESULTS: This study included 199 859 individuals from the 253 administrative divisions in South Korea. Findings indicated that fear was most common in individuals residing in the most deprived areas, followed by those in the mediocre and least deprived areas (fear of infection: odds ratio (OR) 1.05, 95% confidence interval (CI) 1.01-1.09; fear of dying from infection: OR 1.23, 95% CI 1.19-1.28; fear of public criticism: OR 1.20, 95% CI 1.15-1.24; fear of a family member getting infected: OR 1.12, 95% CI 1.07-1.18). CONCLUSIONS: The findings suggest the need to monitor and account for area deprivation in managing the psychological health effects of the COVID-19 crisis.

The association between night eating syndrome and health-related quality of life in Korean adults: a nationwide study.

PURPOSE: Quality of life may be influenced by the presence of eating disorders. This study investigated the association between night eating syndrome (NES) and health-related quality of life in the general population. METHODS: Data were from the 2019 Korea Community Health Survey. The presence of NES was determined using the Night Eating Questionnaire. Health-related quality of life was measured using the 3-level EuroQoL-5 Dimension Index. Multivariable linear regression analyses assessed the association between NES and health-related quality of life. Subgroup analyses were performed based on daily sleep duration. RESULTS: A total of 34,434 individuals aged 19 years or older were included in the study population. Participants with NES (ß = - 4.85, p < 0.001) reported poorer health-related quality of life scores than those without NES. Decreases in health-related quality of life scores among those with NES were greatest in those who slept over 8 h daily (ß = - 12.03, p = 0.004), followed by those who slept less than 6 h (ß = - 5.90, p = 0.006) and participants who slept between 6 and 8 h (ß = - 3.40, p = 0.026) daily. CONCLUSION: Individuals with NES were more likely to have a lower health-related quality of life than those without NES. These findings highlight the potential importance of considering NES in investigating the health-related quality of life. LEVEL OF EVIDENCE: Level III, well-designed case-control analytic studies.

The association between episodes of night eating and levels of depression in the general population.

OBJECTIVE: Research has suggested that a correlation may exist between depressive mood and episodes of night eating. This study aimed to examine whether having episodes of night eating was associated with increased levels of depression. METHOD: This study used data from the 2019 Korea Community Health Survey and the study population consisted of adults aged ≥19 years. Depression levels were measured using the Patient Health Questionnaire-9. We investigated the patients' general characteristics using t-tests and analysis of variance. The association between depression levels and episodes of night eating was analyzed using a multivariable linear regression analysis. Subgroup analysis was conducted based on daily sleep duration. RESULTS: We analyzed 34,358 individuals and found higher average depression scores (ß: 4.99, p < .001) in those with episodes of night eating than those without. Large effect sizes were found for differences in depression scores between participants with and without episodes of night eating. The magnitude of this increase was particularly pronounced in individuals who reported 9 or more hours of sleep per day. DISCUSSION: An association was found between levels of depression and episodes of night eating as individuals with episodes of night eating were more likely to have higher depression scores. Our findings suggest the potential need to consider night eating when addressing the mental health of the general population.

Socheongryongtang suppresses COPD-related changes in the pulmonary system through both cytokines and chemokines in a LPS COPD model.

Context: Socheongryongtang is a traditional Korean medical prescription used to treat pulmonary diseases.Objective: This study investigated the therapeutic mechanism of socheongryongtang for pulmonary diseases.Materials and methods: Seventy BALB/c mice were used: control, 0.8 mg/kg/study LPS intranasal instillation, 1 mg/kg/day Spiriva oral administration for five days, two socheongryongtang groups (150 or 1500 mg/kg/day orally treatment for five days). To illuminate the anti-COPD mechanism, several factors were evaluated such as WBC and differential counts in BALF and IgE in serum, morphological changes, and changes of COPD-related cytokines (TNF-α, IFN-γ, TGF-ß) and chemokines (CXCL1, CCL-2, CCR2) in the lung. In order to confirm the statistical significance, all results were compared under p < 0.01 and p < 0.05.Results: LPS induced a high level of WBC, neutrophils and eosinophils in our in vivo study. Additionally, COPD related cytokines and chemokines such as TNF-α, IFN-γ, TGF-ß, CXCL1, CCL-2 and CCR2 were induced by LPS. Compared to the LPS treatment group, socheongryongtang significantly controlled the level of WBC, neutrophils and eosinophils as well as the level of IgE. It effectively down-regulated the morphological changes, such as fibrosis near bronchoalveolar spaces, small airway destruction (emphysema), etc. It also inhibited the levels of COPD-related cytokines (TNF-α, IFN-γ, TGF-ß) and chemokines (CXCL1, CCL-2, CCR2) compared to the LPS treatment group. In particular, socheongryongtang significantly down-regulated the levels of TNF-α, IFN-γ, and CCR2.Conclusions: Socheongryongtang controlled COPD, but as it has been used as a prescription for respiratory disease, we should additionally evaluate the therapeutic effects against various pulmonary diseases.

Biomass Fly Ash as an Alternative Approach for Synthesis of Amorphous Silica Nanoparticles with High Surface Area.

In this study, the monodisperse amorphous silica nanoparticles (SiO2 NPs) with uniform size distribution and high surface area were successfully synthesized from fly ash as a silica source by chemical sol-gel method. The influence of reaction conditions such as surfactant concentration, aging temperature (Ta), and aging time (Ta) on formation of SiO2 NPs was investigated. Through SEM characterization, it was founded that the uniform and small spherical SiO2 NPs with diameter of 20-30 nm could be synthesized at the appropriate CTAB content of 3 wt%, Ta of 60 °C, and Ta of 8 h. In addition, XRD and nitrogen adsorption-desorption measurements indicated that the SiO2 NPs were obtained under amorphous structure, which possesses a high specific surface area of 408 m2 g-1. The obtained results imply that the successful synthesis of SiO2 NPs from fly ash not only displays an effectively alternative approach to provide high quality SiO2 NPs for various necessary applications but also help solving environmental issues due to large amount of fly ash waste each year.

Association of alcohol drinking with verbal and visuospatial memory impairment in older adults: Clinical Research Center for Dementia of South Korea (CREDOS) study.

BACKGROUND: The study's aim was to examine the association of alcohol consumption with verbal and visuospatial memory impairment in older people. METHODS: Participants were 1,572, aged ≥60 years, in the hospital-based registry of the Clinical Research Center for Dementia of South Korea (CREDOS). Moderate drinking was defined as no more than seven drinks per week and three drinks per day. Memory impairment was defined as performance with more than 1 standard deviation below the mean value on the Seoul Verbal Learning Test and Rey Complex Figure Test. RESULTS: Those who consumed alcohol moderately, compared with abstainers, had a lower odds of verbal memory impairment (Odds Ratio [OR] = 0.64; 95% Confidence Interval [CI]: 0.46-0.87), adjusting for covariates. Visuospatial memory, however, was not significantly associated with alcohol consumption. CONCLUSIONS: Moderate alcohol drinking is associated with a reduced likelihood of verbal memory impairment among older people attending memory clinics.

An Evolutionary Concept Analysis of Pediatric Hospice and Palliative Care.

Purpose: This study aimed to clarify the concept of pediatric hospice and palliative care through conceptual analysis. It also sought to identify the differences between related concepts such as pediatric death care and pediatric spiritual care, in order to provide foundational data for the development of nursing theory and knowledge. Methods: A conceptual analysis of pediatric hospice and palliative care was conducted using Rodgers' evolutionary method. Out of 5,013 papers identified, 28 were selected for detailed reading and analysis. Results: Pediatric hospice and palliative care encompasses physical, psychological, social, mental, spiritual, and family care for children with acute and chronic diseases with uncertain prognoses ahead of death, as well as their families. Effective pediatric hospice and palliative care will require multidisciplinary team nursing, effective communication, and supportive policies. Conclusion: The findings of this study suggest that providing pediatric hospice and palliative care will lead to improvements in pain relief for children and families, the efficiency of responses to death in children, and the quality of life for children and families. The significance of this study is that it clearly clarifies the concept by analyzing pediatric hospice and palliative care using an evolutionary method.

Combined effect of anemia and chronic rhinitis on hearing loss in Korean adults: a nationwide observational study.

Objectives: Studies have suggested an association between hearing loss and anemia. Hearing loss has also been linked to rhinitis, which is characterized by inflammation of the nasal mucous membranes and sinus mucosa. Few studies have concurrently explored the relationships between hearing loss, anemia, and rhinitis. This study was conducted to investigate the association between hearing loss and anemia and to further analyze the potential role of rhinitis in this relationship. Methods: Data were collected from the 2020 Korea National Health and Nutrition Examination Survey. Hearing loss was measured with an audiometer in a soundproof booth and was defined as at least moderate impairment (as indicated by a pure-tone average of ≥41 dB in the better-hearing ear). The association between hearing loss and anemia was analyzed using multivariable logistic regression. The combined effect of anemia and rhinitis on hearing loss was assessed with an interaction term. Results: Among the 2,772 participants, 477 (17.2%) exhibited hearing loss. Participants with anemia were more likely to experience hearing loss than those without anemia (odds ratio [OR], 1.58; 95% confidence interval [CI], 1.07 to 2.33). Furthermore, the odds of hearing loss were greater in participants with both anemia and rhinitis (OR, 3.79; 95% CI, 1.93 to 7.43) relative to those without either condition. Conclusion: Anemia was associated with hearing loss in individuals aged 40 years and older. Based on the analysis of combined effects, participants with anemia and chronic rhinitis were more likely to experience hearing loss than individuals without these conditions.

Effect of motivated physicians and elderly patients with hypertension or type 2 diabetes mellitus in prepared communities on health behaviours and outcomes: A population-based PS matched retrospective cohort study during five-year follow-up period.

Effective chronic disease management requires the active participation of patients, communities, and physicians. The objective of this study was to estimate the effectiveness of the Community-based Registration and Management for elderly patients with Hypertension or Type 2 Diabetes mellitus Project (CRMHDP) by using motivated primary care physicians and patients supported by prepared communities, to utilise healthcare and health outcomes in four cities in South Korea. We conducted a propensity score-matched retrospective cohort study using 2010-2011 as the baseline years, alongside a follow-up period until 2015/2016, based on the Korean National Health Insurance database. Both a CRMHDP group (n = 46,865) and a control group (n = 93,730) were applied against healthcare utilisation and difference-in-differences estimations were performed. For the health outcome analysis, the intervention group (n = 27,242) and control group (n = 54,484) were analysed using the Kaplan-Meier method and Cox proportional hazard regression. Results: The difference-in-differences estimation of the average annual clinic visits per person and the average annual days covered were 1.26 (95% confidence interval, 1.13-1.39) and 22.97 (95% CI, 20.91-25.03), respectively, between the intervention and control groups. The adjusted hazard ratio for death in the intervention group, compared to the control group, was 0.90 (95% CI, 0.86-0.93). For stroke and chronic renal failure, the adjusted hazard ratios for the intervention group compared to the control group were 0.94 (95% CI, 0.88-0.99) and 0.80 (95% CI 0.73-0.89), respectively. Our study suggests that for effective chronic disease management both elderly patients and physicians need to be motivated by community support.

Oxidative and carbonyl stress induced AMD and Codonopsis lanceolata ameliorates AMD via controlling oxidative and carbonyl stress.

Age-related macular degeneration (AMD) is one of the leading causes of blindness. AMD is currently incurable; the best solution is to prevent its occurrence. To develop drugs for AMD, it is crucial to have a model system that mimics the symptoms and mechanisms in patients. It is most important to develop safer and more effective anti-AMD drug. In this study, the dose of A2E and the intensity of blue light were evaluated to establish an appropriate atrophic in vitro model of AMD and anti-AMD effect and therapeutic mechanism of Codonopsis lanceolata. The experimental groups included a control group an AMD group treated with A2E and blue light, a lutein group treated with 25 µM lutein after AMD induction, and three groups treated with different doses of C. lanceolata (10, 20, and 50 µg/mL) after AMD induction. Intrinsic apoptotic pathway (Bcl-2 family), anti-oxidative system (Keap1/Nrf2/HO-1 antioxidant response element), and anti-carbonyl effect (4-hydroxynonenal [4-HNE]) were evaluated using immunofluorescence, MTT, TUNEL, FACS, and western blotting analyses. A2E accumulation in the cytoplasm of ARPE-19 cells depending on the dose of A2E. Cell viability of ARPE-19 cells according to the dose of A2E and/or blue light intensity. The population of apoptotic or necrotic cells increased based on the A2E dose and blue light intensity. Codonopsis lanceolata dose-dependently prevented cell death which was induced by A2E and blue light. The antiapoptotic effect of that was caused by activating Keap1/Nrf2/HO-1 pathway, suppressing 4-HNE, and modulating Bcl-2 family proteins like increase of antiapoptotic proteins such as Bcl-2 and Bcl-XL and decrease of proapoptotic protein such as Bim. Based on these findings, 30 µM A2E and 20 mW/cm2 blue light on adult retinal pigment epithelium-19 cells was an appropriate condition for AMD model and C. lanceolata shows promise as an anti-AMD agent.

Ginseng Berry Juice (GBJ) Regulates the Inflammation in Acute Ulcerative Mouse Models and the Major Bioactive Substances Are Ginsenosides Rb3, Rc, Rd, and Re.

Panax ginseng fruit is known to have various biological effects owing to its large amount of saponins such as ginsenosides. In the present study, ginseng berry juice was confirmed to be effective against acute inflammation. Ginseng berry juice was used for analysis of active constituents, antioxidant efficacy, and in vivo inflammation. A high-performance liquid chromatography method was used for analysis of ginsenosides. In an HCl/ethanol-induced acute gastric injury model, microscopic, immunofluorescent, and immunohistochemical techniques were used for analysis of inhibition of gastric injury and mechanism study. In a mouse model of acute gastritis induced with HCl/ethanol, ginseng berry juice (GBJ, 250 mg/kg) showed similar gastric injury inhibitory effects as cabbage water extract (CB, 500 mg/kg, P.O). GBJ dose-dependently modulated the pro-inflammatory cytokines such as Tumor Necrosis Factor-α (TNF-α), Interleukin-6 (IL-6), and Interleukin-13 (IL-13). GBJ inhibited the activation of Nuclear Factor kappa bB (NF-κB) and suppressed the expressions of cyclooxigenase-2 (COX-2) and prostaglandin 2 (PGE2). The anti-inflammatory effect of GBJ is attributed to ginsenosides which have anti-inflammatory effects. Productivity as an effective food source for acute gastritis was analyzed and showed that GBJ was superior to CB. In addition, as a functional food for suppressing acute ulcerative symptoms, it was thought that the efficacy of gastric protection products would be higher if GBJ were produced in the form of juice rather than through various extraction methods.

5-Fluorouracil, mitomycin-c, and polysaccharide-k versus uracil-ftorafur and polysaccharide-K as adjuvant chemoimmunotherapy for patients with locally advanced gastric cancer with curative resection.

BACKGROUND: Despite the small but significant survival benefit of adjuvant chemotherapy in locally advanced gastric cancer (LAGC), the optimal regimen remains to be determined. We conducted a randomized trial comparing oral (PO) chemoimmunotherapy (CITX) with intravenous (IV) CITX in LAGC patients (stages IB-IIIB) with curative resection (≥ D2 dissection). METHODS: The patients were randomized to the IV (5-fluorouracil 500 mg/m(2) weekly for 24 weeks, mitomycin-C 8 mg/m(2) every 6 weeks × 4) or the PO (uracil-ftorafur (UFT) 400-600 mg/day for 12 months) group. Patients in both groups received PO polysaccharide-K (3 g/day for 4 months). The planned number of patients was 368 for proving the non-inferiority of PO CITX compared to IV CITX for overall survival. RESULTS: The trial was closed prematurely after enrolling 82 patients (44 in the IV group, 38 in the PO group). With a median follow-up of 82 months, there were no significant differences in the 5-year disease-free survival (73% vs. 55%, p = 0.358) and overall survival (77% vs. 66%, p = 0.159) between the 2 groups. The IV group demonstrated a higher incidence of grade 2 or 3 neutropenia, thrombocytopenia, and vomiting. CONCLUSIONS: PO CITX with UFT appeared to be at least non-inferior to 5-fluorouracil and mitomycin-C CITX, with lower toxicity in the adjuvant treatment for LAGC.

Is COVID-19 induced reductions in the level of physical activity associated with increased depressive symptoms in patients with hypertension?

BACKGROUND: Studies have reported that the coronavirus 2019 (COVID-19) outbreak led to reduced levels of physical activity, but this has been rarely studied in patients with hypertension. This study investigated the association between depressive symptoms and changes in physical activity of patients with hypertension during the COVID-19 outbreak. METHODS: Data were from the Korea Community Health Survey (KCHS), conducted between August to November 2020. The KCHS is a nationwide cross-sectional survey that evaluates information on various sociodemographic, economic, and health related variables. Depressive symptoms were measured using the Patient Health Questionnaire-9. Physical activity was measured using a questionnaire inquiring whether participants experienced any changes in physical activity after the pandemic. The association between depressive symptoms and changes in physical activity level were analyzed using a multivariable logistic regression analysis. RESULTS: Out of 55,203 patients, 39.6% responded that they had experienced lower levels of physical activity due to the pandemic and showed increased likelihoods of depressive symptoms (OR 1.33, 95% CI 1.14-1.54) than individuals who responded that they had performed similar levels of physical activity. This tendency was stronger in patients that did not receive treatment for hypertension (OR 2.07, 95% CI 1.02-4.23) than those who did receive treatment with marginal significance (p-value of interaction term: 0.1241). CONCLUSIONS: Decreased levels of physical activity due to the outbreak was experienced by a noticeable proportion of patients with hypertension and was associated with increased likelihoods of depressive symptoms.
