RESUMEN
BACKGROUND: Lower urinary tract symptoms (LUTS) including frequency, nocturia, urgency, and incontinence, are common in women and cause significant discomfort in daily life. However, diagnosis and treatment of LUTS are often delayed because many patients with such symptoms do not complain to the physician of discomfort and do not seek medical attention. LUTS are known to be associated with muscle weakness. We investigated the association between grip strength and LUTS in women of different ages. METHODS: This study included 4225 women (mean age 48.6 years) who underwent self-referred health screening between April 2015 and December 2019. LUTS were evaluated using a self-reported questionnaire, and the overactive bladder symptom score was used to screen for an overactive bladder. Low muscle strength was defined as a hand grip strength of < 18 kg (decreased grip strength). RESULTS: We observed decreased grip strength in 13.7% (n = 580) of the participants. Nocturia, urgency, incontinence, and overactive bladder were more common in women with decreased grip strength than in women with normal grip strength. After adjusting for age, comorbidities (hypertension, diabetes, hyperlipidemia), smoking status, alcohol consumption, regular exercise, and stress, nocturia (odds ratio [OR] 1.19, 95% confidence interval [CI] 1.01-1.52), urinary incontinence (OR 1.32, 95% CI 1.01-1.72), and an overactive bladder (OR 1.75, 95% CI 1.35-2.27) were significantly associated with decreased grip strength. CONCLUSIONS: The findings suggest that LUTS, especially nocturia, incontinence, and an overactive bladder are associated with decreased grip strength in women. Therefore, physicians should be aware that patients may not seek help, even if they are uncomfortable, and it is important to obtain a detailed medical history and perform additional tests, even in the absence of complaints, in patients with low grip strength, who are at high risk of LUTS.

Despite the controversy surrounding electronic cigarette (e-cigarette) safety, global consumption has been rapidly increasing. We investigated the relationship between e-cigarette use and mental health conditions in adults of various ages.We conducted a secondary data analysis of adults aged 19 to 80 who participated in the first year of the 7th Korea National Health and Nutrition Examination Survey (2016). The total number of participants was 5469, including 3398 non-smokers, 1700 smokers who had never used e-cigarettes, and 371 smokers who had previously used e-cigarettes, selected based on self-report questionnaires. Mental health factors including stress status, depressive mood, suicide plan, and suicide attempt were assessed by self-reported questionnaire. The Patient Health Questionnaire (PHQ-9) was used to assess depressive mood, with a cut-off value of 10. The relationship between e-cigarette use and stress status with depressive mood were analyzed with adjustment for potential confounders.Both male and female smokers who previously used e-cigarettes showed higher levels of stress than non-smokers or smokers who had never used e-cigarettes. The average PHQ-9 score was higher among previous e-cigarette-using smokers relative to non-smokers and smokers who had never used e-cigarettes, regardless of gender. The number of participants with depressive mood was significantly higher in the group of smokers who previously used e-cigarettes. In multivariable-adjusted logistic regression analyses, there was a significantly higher odds ratio for higher stress in male smokers who had previously used e-cigarettes and for depressive mood in female smokers who had previously used e-cigarettes, compared with non-smokers.This study analyzed the association between adult e-cigarette use and mental health conditions, including stress and depressive mood, and showed that e-cigarette use was significantly related to both conditions in men and women.

The present study investigated whether electronic cigarette use, which is becoming increasingly common, was related to systemic inflammation that may lead to cardiovascular disease, similar to conventional cigarette smoking. The study included 1208 men (19-65 years old) who participated in the 7th Korean National Health and Nutrition Examination Survey (2016). The participants were categorized as electronic cigarette users, conventional cigarette users, and nonsmokers. Serum high-sensitivity C-reactive protein was used as an inflammatory index, and uric acid level was used as a metabolic indicator. After adjusting for confounding factors, electronic cigarette use was significantly associated with elevated serum high-sensitivity C-reactive protein levels (ß = 1.326, P = .002), uric acid levels (ß = 0.400, P = .042), and hyperuricemia (uric acid level of >7 mg/mL; odds ratio = 2.67, 95% confidence interval = 1.27-5.58). These findings suggest that electronic cigarette use may be associated with systemic inflammation markers, similar to conventional cigarette use.

Sleep debt is known to have harmful effects on health. Weekend catch-up sleep (CUS) is a behavior to cope with weekday sleep debt. However, it is unclear whether weekend CUS has advantageous effects on health because sleep hygiene guidelines recommend regularizing bed time and arousal time. The aim of this study was to identify whether weekend CUS behavior has an association with better health-related quality of life (HRQoL)According to the inclusion criteria, 4871 participants were selected from the 2016 Korea National Health and Nutrition Examination Survey. Sleep questionnaires and European quality of life scale-5 dimensions (EQ-5D) questionnaire were used to collect data about the participants' sleep patterns and HRQoL. Odds ratios (ORs) with 95% confidence intervals (95% CIs) for each dimensional problem of EQ-5D were derived by logistic regression. Mean EQ-5D index scores were compared between weekend CUS and non-CUS groups based on their weekday sleep durations and quintile of chronotype.The ORs of dimensional problems of HRQoL of non-CUS group versus weekend CUS group were 1.63 (95% CI 1.07, 2.47) for usual activities, and 1.45 (95% CI 1.11, 1.90) for anxiety/depression. Mean EQ-5D scores of the weekend CUS group were significantly higher than those of the non-CUS group for sleeping less than 6âhours (0.953â±â0.004 vs 0.936â±â0.007, Pâ=â.036) and sleeping 6 to 7âhours (0.965â±â0.003 vs 0.955â±â.0.004, Pâ=â.045). These findings were similar in the fourth quintile (Q4) of chronotype (0.965â±â0.007 vs 0.951â±â0.008, Pâ=â.008) and fifth quintile (Q5) (0.952â±â0.006 vs 0.941â±â0.007, Pâ=â.022).Weekend CUS behavior was associated with better HRQoL than non-CUS among Korean adults. Especially, it was significant in participants who slept for less than 7âhours or participants whose chronotype was the fourth or fifth quintile. Attention may be needed for subjects with sleep short time and later chronotype who do not have weekend-CUS behaviors, because there is a risk that their HRQoL might be compromised.

PURPOSE: Spontaneous echo-contrast (SEC) appears on B-mode images as moving curls of smoke in the lumen of veins. The aims of this study were to investigate the prevalence and characteristics of internal jugular vein SEC among patients with stroke, in comparison with control subjects. METHODS: We enrolled 97 Korean patients with acute ischemic stroke and 50 controls. Both internal jugular veins were examined for the presence and severity of SEC and measurement of flow velocity. Venous samples were obtained for laboratory evaluation of hematologic factors. RESULTS: In 294 internal jugular veins, the prevalence of SEC was 81% in stroke patients and 68% in controls (odds ratio, 2.0; 95% confidence interval, 1.1-3.6; p = 0.013). Stroke patients were more likely to have SEC on the left (p = 0.025) than on the right (p = 0.184) internal jugular vein. Overall, the association between stroke and SEC remained significant after adjustment for other variables (odds ratio, 4.3; 95% confidence interval, 1.7-10.8; p = 0.002). CONCLUSIONS: Internal jugular vein SEC was found more frequently in stroke patients than in controls. However, local as well as systemic factors must be considered in the interpretation of this finding.

The potential relationship between vitamin D (VitD) status and metabolic control in patients with type 2 diabetes mellitus (T2DM) warrants further study. We aimed to evaluate the relationship between the serum 25-hydroxyvitamin D [25(OH)D] level and various parameters in patients with T2DM. We analyzed retrospectively data from 276 Korean patients with T2DM whose serum 25(OH)D level was measured in our hospital. Nondiabetic healthy subjects who visited the hospital for health screening were selected as the control group (Non-DM, n=160). Compared with control subjects, patients with T2DM had a lower serum 25(OH)D level (15.4±0.5 vs. 12.9±0.4 ng/ml, p<0.01). Eleven percent of T2DM patients were VitD "insufficient" (20-29 ng/ml) and 87% of the patients were VitD "deficient" (<20 ng/ml). The serum 25(OH)D level was significantly related to serum fibrinogen, triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), ferritin, the urine albumin creatinine ratio, and hemoglobin A(1C) (HbA1C). In a multivariate logistic regression analysis, high levels of HbA1C, TG, and LDL-C were independently associated with VitD deficiency in T2DM patients. The results of the present study show that the majority of Koreans with T2DM are VitD deficient, and the serum 25(OH)D level in patients with T2DM is related to lipid and glucose parameters. Further studies are required of the relationship of VitD with fibrinogen and other related parameters.
RESUMEN
Objectives. Human placental extract (HPE) has begun to be used in Korea in various ways to improve health, even though evidence-based data is insufficient. This study investigated the effects of HPE on health status in elderly Koreans. Design. Randomized, single-blind, and case-control study design. Setting and Participants. Thirty-nine community-dwelling healthy Koreans ≥65 years of age. Intervention. The participants were randomly categorized into a placebo group (n = 17) and HPE group (n = 22). The HPE group received abdominal subcutaneous injections of HPE for 8 weeks. The placebo group was injected with normal saline. Measurements. The degree of health status was surveyed by the Korean health status measure for the elderly (KoHSME V1.0) at baseline and the end of the study. Results. In the HPE group, the scores of physical function, sexual life, and general heath perception at the end of the study period were significantly improved from baseline (P = .007, .020, and .005, resp.), while the health status of the placebo group remained unchanged during the study period. There was a significant difference over the study period between the two groups in the mean change of the physical function score (P = .036). Conclusion. A HPE injection regimen can improve the health status in elderly Koreans.
RESUMEN
BACKGROUND: Pulse wave velocity (PWV) and ankle-brachial pressure index (ABI) are non-invasive tools to measure atherosclerosis and arterial stiffness. Heart rate variability (HRV) has proven to be a non-invasive powerful tool in the investigation of the autonomic cardiovascular control. Therefore, the purpose of this study was to determine the relationship among PWV, ABI, and HRV parameters in adult males. METHODS: The study was carried out with 117 males who visited a health care center from April, 2009 to May, 2010. We conducted blood sampling (total cholesterol, triglyceride, high density lipoprotein, cholesterol, fasting glucose) and physical examination. We studied brachial-ankle PWV (baPWV) and ABI. We examined HRV parameters including standard deviation of NN interval (SDNN), low frequency (LF), high frequency (HF), LF/HF ratio. We analyzed the relationship among baPWV, ABI, and HRV parameters. RESULTS: SDNN had a significant negative correlation with age, systolic blood pressure and heart rate. LF and HF had a significant negative correlation with age, and age and heart rate, respectively. baPWV was significantly and positively associated with age, systolic and diastolic blood pressures, total cholesterol, fasting glucose and heart rate. ABI was negative correlated significantly with systolic and diastolic blood pressures and heart rate. After adjusting for all associated variables, baPWV was not correlated with HRV parameters, but there was a significant positive association between SDNN and ABI (r = 0.195, P = 0.014). CONCLUSION: SDNN of HRV parameters had a significant positive correlation with ABI.
RESUMEN
OBJECTIVE: In Korea, human placental extract (HPE) has recently been used to treat various diseases (chronic liver diseases, menopause syndrome, chronic fatigue, skin pigment diseases, etc.), but evidence-based studies are not yet sufficient. The aim of this study was to examine the effects of HPE on menopausal symptoms, fatigue, and risk factors for cardiovascular disease in middle-aged Korean women in a randomized controlled trial. DESIGN: Korean women, aged 40 to 64 years, with menopausal symptoms and fatigue were recruited as participants. The women were randomly assigned to a placebo group or an HPE group. The HPE group received subcutaneous injections of HPE in the abdomen for 8 weeks, whereas the placebo group received normal saline. Then, the Menopause Rating Scale, and Fatigue Severity Scale, and Visual Analog Scale were administered, and risk factors for cardiovascular disease were assessed. RESULTS: The Menopause Rating Scale total baseline score was not different between the two groups; however, the score of the HPE group decreased significantly at 8 weeks compared with that of the placebo group (P = 0.033). Fatigue Severity Scale and Visual Analog Scale scores of the placebo group did not change, whereas the scores of the HPE group decreased significantly during the study period (Fatigue Severity Scale, P = 0.002; Visual Analog Scale, P = 0.001). The baseline 17beta-estradiol level was not significantly different between the two groups, but the 17beta-estradiol level of the HPE group was significantly increased at 8 weeks compared with that of the placebo group (P = 0.031). No changes in risk factors for cardiovascular disease were observed in either group. CONCLUSIONS: Menopausal symptoms and fatigue in middle-aged Korean women improved after 8 weeks of HPE treatment, whereas risk factors for cardiovascular disease did not change during the study period.
