Association of the triglyceride-glucose index with early-onset atherosclerotic cardiovascular disease events and all-cause mortality: a prospective cohort study.

BACKGROUND: The association between the triglyceride glucose (TyG) index and the risk of early-onset atherosclerotic cardiovascular disease (ASCVD) events or all-cause mortality in young and middle-aged people is not fully elucidated. METHODS: The present study included 64,489 young and middle-aged people who participated in the 2006 Kailuan Study physical examination. Multivariate Cox proportional hazards models and restricted cubic spline curves were used to assess the association of TyG index with early-onset ASCVD events and all-cause mortality. RESULTS: During a median of 11-year follow-up, 1984 (3.08%) participants experienced at least one ASCVD event and 1,392 (2.16%) participants experienced all-cause death. A higher TyG index was significantly associated with a higher risk of early-onset ASCVD events (HR: 1.61, 95% CI 1.38-1.89) and all-cause mortality (HR: 1.39, 95% CI 1.17-1.65), respectively. For each unit increase in TyG index, the risk of early-onset ASCVD events increased by 20%. In addition, there was a non-linear association between the TyG index and early-onset ASCVD events (P for non-linear < 0.01), and a linear association between TyG index and all-cause mortality (P for non-linear = 0.476). CONCLUSIONS: A higher TyG index is significantly associated with an increased incidence of early-onset ASCVD events and all-cause mortality in a young and middle-aged population from North China.

Feasibility of Colorectal Endoscopic Submucosal Dissection in Elderly Patients: The Impact of Sarcopenia.

INTRODUCTION: Colorectal cancer is a public health concern associated with high incidence rates. Sarcopenia is a known risk factor for postoperative complications, although an association between increased complications after colorectal endoscopic submucosal dissection (ESD) and sarcopenia remains undocumented. Herein, we aimed to explore the feasibility of colorectal ESD in patients with sarcopenia. METHODS: This retrospective study included 499 patients (69 with and 430 without sarcopenia). We evaluated the short- and long-term outcomes of colorectal ESD. RESULTS: There were no significant differences between the two groups regarding en bloc, R0, or curative resection rates. However, poor bowel preparation was significantly more common in the sarcopenia group. Moreover, patients with sarcopenia exhibited a significant increase in complications (37.7% vs. 10.5%). Multivariate analysis revealed that sarcopenia (odds ratio [OR]: 3.78, 95% confidence interval [Cl]: 1.85-7.73, p < 0.001), anticoagulation therapy (OR: 3.59, 95% Cl: 1.86-6.92, p < 0.001), procedure time (OR: 1.28, 95% Cl: 1.11-1.47, p < 0.001), and resection size (OR: 1.25, 95% Cl: 1.03-1.52, p = 0.02) were significantly correlated with the Common Terminology Criteria for Adverse Events (CTCAE) ≥ grade 2. The correlation between sarcopenia and CTCAE ≥ grade 2 was maintained after matching, resulting in more extended hospital stays in patients with sarcopenia. However, we detected no association between sarcopenia and overall survival and ESD-related death. CONCLUSION: Sarcopenia is a risk factor for complications in colorectal ESD, suggesting that colorectal ESD could be performed for patients with sarcopenia, although much caution should be taken.

Self-concealment scale (SCS) in middle-aged people: psychometric features and cross-age equivalence test.

BACKGROUND: Individuals' concealment of negative information and privacy may lead to impaired social interactions and threatened health conditions. This study aimed to investigate the effectiveness of the Self-Concealment Scale (SCS) in the middle-aged Chinese population and to examine the equivalence of the SCS among different age groups. METHODS: The current research adopted the SCS, Distress Disclosure Index (DDI), Revised Cheek and Buss Shyness Scale (RCBS), Social Interaction Anxiety Scale (SIAS), Social Phobia Scale (SPS), UCLA Loneliness Scale (ULS-8), and Kessler Psychological Distress Scale (K10) to survey 1124 middle-aged people. To explore the factor structure of the SCS, the study employed exploratory factor analysis and confirmatory factor analysis. The reliability of the SCS was measured based on Cronbach's α coefficients, McDonald's Omega coefficients, and split-half reliability. Correlation analysis was applied to examine the relationship between SCS and RCBS, SIAS, SPS, ULS-8, and K10. Moreover, this study recruited 1458 emerging adults and 1104 older adults to identify the cross-age invariance of the SCS. RESULTS: Exploratory factor analysis of the middle aged adults' data supported a single factor model. The factor loadings of SCS items ranged from 0.62 to 0.73, the commonality ranged from 0.39 to 0.53, and the single-factor model fitted well. The scale showed a Cronbach's α coefficient value of 0.895, McDonald's Omega coefficient of 0.893, and a split-half reliability coefficient value of 0.861. In addition, the SCS demonstrated invariance in emerging adults, middle-aged adults, and older adults. Further analysis showed that the scores of the SCS (F = 3.55, p = 0.029) among emerging adults (M = 26.43, SD = 7.96) were significantly higher than among middle-aged (M = 25.77, SD = 7.79), and older cohort (M = 25.69, SD = 7.91). CONCLUSION: The SCS revealed favorable psychometric characteristics among the middle-aged Chinese population. The degree of self-concealment among emerging adults was higher than that of middle-aged and older people.

Social participation and mental well-being: Does purpose in life mediate the association among older adults?

OBJECTIVES: We investigated the association of social participation with mental well-being among older people and whether purpose in life mediates the potential association. METHOD: Cross-sectional (n = 1014) and longitudinal (n = 660, four-year follow-up) data comprised of three age cohorts (75, 80, and 85 years) of community-dwelling people. Life satisfaction was measured with the Satisfaction with Life Scale, depressive symptoms with the Centre for Epidemiologic Studies Depression Scale, and purpose in life with the Scales of Psychological Well-Being purpose in life subscale. Social participation was assessed with questions concerning the frequency of meeting close friends and acquaintances, and volunteering. The data were analyzed using structural equation modeling. RESULTS: Higher social participation was associated with higher life satisfaction and fewer depressive symptoms both cross-sectionally and after a four-year follow-up. Higher purpose in life mediated the associations of more social participation with higher life satisfaction and fewer depressive symptoms cross-sectionally. In the longitudinal data, the mediation effect was not observed. CONCLUSION: Older people with frequent social participation who had a sense of purpose in their lives will likely have higher mental well-being than those with less social participation. Enabling and supporting them to conduct purposeful actions in social contexts may help maintain their mental well-being.

[Statistical modeling of the fact and requests frequency for emergency medical care by primary care different age groups patients.]

The frequency of seeking emergency medical care (EC) can be mediated by the characteristics of the patient's social status, his health literacy (HL) but not only by the clinical signs of the disease, health status. The goal of the cross-sectional survey was to identify factors determining the frequency of applying for EC by the young-aged, middle-aged (18-59 years) and elderly (60-74 years) patients of the primary health organizations in the Arkhangelsk Region and the Komi Republic (North-West Russia). Logistic regression (LR) was used to identify factors mediating the fact of applying for EC; zero-inflated negative binomial regression (ZINB) - to identify factors mediating the frequency of appeals. The majority of elderly respondents in the Arkhangelsk Region (72,5%) and the Komi Republic (74,1%) applied for EC at least once during the calendar year; among the young-aged and middle-aged respondents - 45,3% and 52,1% respectively. In the group of young-aged and middle-aged respondents, a higher frequency of appeals for EC is mediated by the age, low self-esteem of the well-being and health status, a chronic disease(s) affecting daily well-being in anamnesis, a low level of HL; in the group of the elderly respondents - by the fact of absence of a spouse, low self-esteem of the well-being, a chronic disease(s) affecting daily well-being in anamnesis, low levels of HL respectively. The obtained results obtained can be used to identify the «risk group¼ of patients of the primary health organizations who have a higher probability of applying for EC, and to organize additional preventive work with the min primary health organizations.

Age- and sex-specific effects of a long-term lifestyle intervention on body weight and cardiometabolic health markers in adults with prediabetes: results from the diabetes prevention study PREVIEW.

AIMS/HYPOTHESIS: Lifestyle interventions are the first-line treatment option for body weight and cardiometabolic health management. However, whether age groups or women and men respond differently to lifestyle interventions is under debate. We aimed to examine age- and sex-specific effects of a low-energy diet (LED) followed by a long-term lifestyle intervention on body weight, body composition and cardiometabolic health markers in adults with prediabetes (i.e. impaired fasting glucose and/or impaired glucose tolerance). METHODS: This observational study used longitudinal data from 2223 overweight participants with prediabetes in the multicentre diabetes prevention study PREVIEW. The participants underwent a LED-induced rapid weight loss (WL) period followed by a 3 year lifestyle-based weight maintenance (WM) intervention. Changes in outcomes of interest in prespecified age (younger: 25-45 years; middle-aged: 46-54 years; older: 55-70 years) or sex (women and men) groups were compared. RESULTS: In total, 783 younger, 319 middle-aged and 1121 older adults and 1503 women and 720 men were included in the analysis. In the available case and complete case analyses, multivariable-adjusted linear mixed models showed that younger and older adults had similar weight loss after the LED, whereas older adults had greater sustained weight loss after the WM intervention (adjusted difference for older vs younger adults -1.25% [95% CI -1.92, -0.58], p<0.001). After the WM intervention, older adults lost more fat-free mass and bone mass and had smaller improvements in 2 h plasma glucose (adjusted difference for older vs younger adults 0.65 mmol/l [95% CI 0.50, 0.80], p<0.001) and systolic blood pressure (adjusted difference for older vs younger adults 2.57 mmHg [95% CI 1.37, 3.77], p<0.001) than younger adults. Older adults had smaller decreases in fasting and 2 h glucose, HbA1c and systolic blood pressure after the WM intervention than middle-aged adults. In the complete case analysis, the above-mentioned differences between middle-aged and older adults disappeared, but the direction of the effect size did not change. After the WL period, compared with men, women had less weight loss (adjusted difference for women vs men 1.78% [95% CI 1.12, 2.43], p<0.001) with greater fat-free mass and bone mass loss and smaller improvements in HbA1c, LDL-cholesterol and diastolic blood pressure. After the WM intervention, women had greater fat-free mass and bone mass loss and smaller improvements in HbA1c and LDL-cholesterol, while they had greater improvements in fasting glucose, triacylglycerol (adjusted difference for women vs men -0.08 mmol/l [-0.11, -0.04], p<0.001) and HDL-cholesterol. CONCLUSIONS/INTERPRETATION: Older adults benefited less from a lifestyle intervention in relation to body composition and cardiometabolic health markers than younger adults, despite greater sustained weight loss. Women benefited less from a LED followed by a lifestyle intervention in relation to body weight and body composition than men. Future interventions targeting older adults or women should take prevention of fat-free mass and bone mass loss into consideration. CLINICAL TRIAL REGISTRATION NUMBER: ClinicalTrials.gov NCT01777893.

Prognostic Factors Affecting Short- and Long-Term Outcomes of Gastrectomy for Gastric Cancer in Older Patients.

INTRODUCTION: The benefits of surgery in older patients with gastric cancer are controversial. This single-institution retrospective study in Japan aimed to evaluate the impact of gastrectomy in older patients with gastric cancer. METHODS: A series of 234 patients aged ≥80 years with histologically confirmed gastric cancer had indications for surgical treatment at the Gastroenterological Center, Yokohama City University Medical Center, between April 2002 and December 2018. Patients who were lost to follow-up (n = 27), had tumors not eligible for surgery (n = 14), and could not achieve R0 resection (n = 7) were excluded from this retrospective study. The remaining 186 patients were included. Patient characteristics, intraoperative outcomes, postoperative complications, and long-term survival were evaluated. RESULTS: The incidence of postoperative complications with Clavien-Dindo grade ≥ II was observed in 61 patients (32.8%). The 5-year relapse-free survival and overall survival (OS) rates were 84.2% and 63.4%, respectively. Multivariate analysis showed that geriatric nutritional risk index (<98) (odds ratio, 1.97; p = 0.047), neutrophil/lymphocyte ratio (>2.36) (odds ratio, 1.94; 95% confidence interval, 1.02-3.67; p = 0.043), and total gastrectomy (TG) (odds ratio, 1.97; p = 0.042) significantly predicted postoperative complications. Moreover, TG (hazard ratio, 1.91; p = 0.036) was an independent prognostic factor of OS. CONCLUSIONS: Poor immunonutritional status and TG led to worse short-term outcomes. Moreover, TG was an independent prognostic factor of OS in older patients with gastric cancer. It is necessary to provide effective perioperative care, including nutritional support, to clarify whether short-term outcomes would be improved.

Application of machine learning model to predict osteoporosis based on abdominal computed tomography images of the psoas muscle: a retrospective study.

BACKGROUND: With rapid economic development, the world's average life expectancy is increasing, leading to the increasing prevalence of osteoporosis worldwide. However, due to the complexity and high cost of dual-energy x-ray absorptiometry (DXA) examination, DXA has not been widely used to diagnose osteoporosis. In addition, studies have shown that the psoas index measured at the third lumbar spine (L3) level is closely related to bone mineral density (BMD) and has an excellent predictive effect on osteoporosis. Therefore, this study developed a variety of machine learning (ML) models based on psoas muscle tissue at the L3 level of unenhanced abdominal computed tomography (CT) to predict osteoporosis. METHODS: Medical professionals collected the CT images and the clinical characteristics data of patients over 40 years old who underwent DXA and abdominal CT examination in the Second Affiliated Hospital of Wenzhou Medical University database from January 2017 to January 2021. Using 3D Slicer software based on horizontal CT images of the L3, the specialist delineated three layers of the region of interest (ROI) along the bilateral psoas muscle edges. The PyRadiomics package in Python was used to extract the features of ROI. Then Mann-Whitney U test and the least absolute shrinkage and selection operator (LASSO) algorithm were used to reduce the dimension of the extracted features. Finally, six machine learning models, Gaussian naïve Bayes (GNB), random forest (RF), logistic regression (LR), support vector machines (SVM), Gradient boosting machine (GBM), and Extreme gradient boosting (XGBoost), were applied to train and validate these features to predict osteoporosis. RESULTS: A total of 172 participants met the inclusion and exclusion criteria for the study. 82 participants were enrolled in the osteoporosis group, and 90 were in the non-osteoporosis group. Moreover, the two groups had no significant differences in age, BMI, sex, smoking, drinking, hypertension, and diabetes. Besides, 826 radiomic features were obtained from unenhanced abdominal CT images of osteoporotic and non-osteoporotic patients. Five hundred fifty radiomic features were screened out of 826 by the Mann-Whitney U test. Finally, 16 significant radiomic features were obtained by the LASSO algorithm. These 16 radiomic features were incorporated into six traditional machine learning models (GBM, GNB, LR, RF, SVM, and XGB). All six machine learning models could predict osteoporosis well in the validation set, with the area under the receiver operating characteristic (AUROC) values greater than or equal to 0.8. GBM is more effective in predicting osteoporosis, whose AUROC was 0.86, sensitivity 0.70, specificity 0.92, and accuracy 0.81 in validation sets. CONCLUSION: We developed six machine learning models to predict osteoporosis based on psoas muscle images of abdominal CT, and the GBM model had the best predictive performance. GBM model can better help clinicians to diagnose osteoporosis and provide timely anti-osteoporosis treatment for patients. In the future, the research team will strive to include participants from multiple institutions to conduct external validation of the ML model of this study.

Association between Sarcopenia and Depressive Symptoms in Community-Dwelling People Aged 40 Years and Older.

Several studies have reported an association between sarcopenia and depression. Their results, however, are inconsistent, partly due to small sample sizes and lack of consideration of important confounders. The present study aimed to cross-sectionally examine this association in community-dwelling people in Japan. This study used baseline data from the Yuzawa cohort study (age ≥ 40 years), with the final analysis population comprising 2,466 participants. A self-administered questionnaire was used to elicit information related to sarcopenia, depressive symptoms, demographic characteristics, anthropometrics, disease history, and lifestyles. Sarcopenia was diagnosed using SARC-F, a validated questionnaire including components of Strength, Assistance in walking, Rising from a chair, Climbing stairs, and Falls. Depressive symptoms were assessed using the 11-item version of the Center for Epidemiologic Studies Depression Scale (CES-D). For depressive symptoms, prevalence ratios (PRs) were calculated, and odds ratio (ORs) were obtained using simple and multiple logistic regression analyses. Mean age of participants was 61.7 years (standard deviation = 11.8), and 10.5% and 34.7% had sarcopenia and depressive symptoms, respectively. Sarcopenic individuals had a significantly higher PR (2.00), unadjusted OR (3.67), and adjusted OR (4.96) compared to non-sarcopenic individuals, with an estimated adjusted PR of 2.7. There was a significant dose-dependent association between SARC-F scores and depressive symptoms in sarcopenic individuals (adjusted P for trend = 0.0028). In conclusion, sarcopenia and depressive symptoms were robustly associated in community-dwelling, middle-aged and older people in Japan. However, the direction of this association is unclear, and a future cohort study will be needed to determine causality.

Frequency of median nerve tightness and its association with upper limb functions among smartphone users of a public sector university, Karachi.

OBJECTIVE: To determine median nerve tightness in smartphone users, and to compare the upper limb functions between those with and without median nerve tightness. Methods: The cross-sectional, observational study was conducted at the Institute of Physical Medicine and Rehabilitation, Dow University of Health Sciences, Karachi, from March 2020 to January 2021, and comprised subjects of either gender aged 20-40 years who had been using smartphone for >1 year. Body mass index was calculated. The participants were evaluated using upper extremity functional index-15. A hand-held dynamometer was used to assess handgrip strength, and a pinch meter assessed the pinch strength. Manual upper limb tension test 1 was used for median nerve tightness. Frequencies and percentages were drawn for all categorical variables. Data was analysed using SPSS 22. RESULTS: Of the 277 subjects, 198(71.5%) were females. The largest group 176(63.5%) was aged 21-25 years. The mean upper limb functional index was 84.24±15.09. Also, 113(40.8%) subjects were positive for left-side median nerve tightness and 122(44%) were positive on the right side. There was no significant association between median nerve tightness and upper extremity function (p>0.05). The association, however, was significant with the duration of mobile usage in years (p<0.05). Conclusion: Prolonged overuse of smartphone may lead to symptoms of median nerve tightness, but it was not found to have an effect on upper limb function, handgrip and pinch strength.

Respiratory Muscle Weakness as a Risk Factor for Pneumonia in Older People.

INTRODUCTION: The respiratory muscle strength regulates the effectiveness of coughing, which clears the airways and protects people from pneumonia. Sarcopenia is an aging-related loss of muscle mass and function, the worsening of which is associated with malnutrition. The loss of respiratory and swallowing muscle strength occurs with aging, but its effect on pneumonia is unclear. This study aimed to determine the risks of respiratory muscle weakness on the onset and relapse of pneumonia in older people in conjunction with other muscle-related factors such as malnutrition. METHODS: We conducted a longitudinal study with 47 pneumonia inpatients and 35 non-pneumonia controls aged 70 years and older. We evaluated the strength of respiratory and swallowing muscles, muscle mass, and malnutrition (assessed by serum albumin levels and somatic fat) during admission and confirmed pneumonia relapse within 6 months. The maximal inspiratory and expiratory pressures determined the respiratory muscle strength. Swallowing muscle strength was evaluated by tongue pressure. Bioelectrical impedance analysis was used to evaluate the muscle and fat mass. RESULTS: The respiratory muscle strength, body trunk muscle mass, serum albumin level, somatic fat mass, and tongue pressure were significantly lower in pneumonia patients than in controls. Risk factors for the onset of pneumonia were low inspiratory respiratory muscle strength (odds ratio [OR], 6.85; 95% confidence interval [CI], 1.56-30.11), low body trunk muscle mass divided by height2 (OR, 6.86; 95% CI, 1.49-31.65), and low serum albumin level (OR, 5.46; 95% CI, 1.51-19.79). For the relapse of pneumonia, low somatic fat mass divided by height2 was a risk factor (OR, 20.10; 95% CI, 2.10-192.42). DISCUSSION/CONCLUSIONS: Respiratory muscle weakness, lower body trunk muscle mass, and malnutrition were risk factors for the onset of pneumonia in older people. For the relapse of pneumonia, malnutrition was a risk factor.

Decreasing trends in potentially inappropriate medications in older people: a nationwide repeated cross-sectional study.

BACKGROUND: Potentially Inappropriate Medications (PIMs) and polypharmacy are widely used indicators of suboptimal prescribing for older people. The aim of this study was to describe the changes in the prevalence of PIMs and polypharmacy among people aged 75 years and over between 2011 and 2019 in France. METHODS: PIMs and polypharmacy were assessed among people aged 75 years and over every two years between 2011 and 2019 using the French health insurance data system. Sixteen PIM criteria from the 2015 Beers and STOPP lists were assessed. Polypharmacy (5 to 9 drugs) and hyper-polypharmacy (≥10 drugs) were defined based on the average number of drugs dispensed per quarter. The Annual Percent Change (APC) and 95%CI were assessed using linear regression models after standardization of the prevalence on age and sex. RESULTS: The study population included 5,777,645 individuals over 75 years old in 2011 and 6,328,155 in 2019. The prevalence of PIMs decreased from 49.6 to 39.6% over the study period (APC: - 1.19% [- 1.35;-1.04]). Of the sixteen indicators assessed, the prevalence of thirteen decreased between 2011 and 2019. Benzodiazepines were the most frequent PIMs (34.7% in 2011 to 26.9% in 2019), followed by anticholinergic drugs (12.1% in 2011 to 8.3% in 2019), oral non-steroidal anti-inflammatory drugs (11.4 to 7.8%), and PIMs related to antihypertensive drugs (7.4 to 6.0%). Overall, women and individuals aged 85 years and older were more likely to receive PIMs. The prevalence of hyper-polypharmacy decreased from 30.5 to 25.9% over the study period. CONCLUSION: This study, which is the first to assess the change in prevalence of PIMs and polypharmacy over time from comprehensive health data in France, highlights that PIMs and hyper-polypharmacy declined between 2011 and 2019. However, PIMs remains frequent for older people and often involves benzodiazepines.

Do opposite ends of same factors underlie life satisfaction vs. depressive symptoms among older people?

BACKGROUND: Although depressive symptoms are more common among older than younger age groups, life satisfaction tends to remain stable over the life course, possibly because the underlying factors or processes differ. AIM: To study whether the factors that increase the likelihood of high life satisfaction also decrease the likelihood of depressive symptoms among older people. METHODS: The data were a population-based probability sample drawn from community-dwelling people aged 75, 80, and 85 years (n = 1021). Participants' life satisfaction was measured with the Satisfaction with Life Scale and depressive symptoms with the Centre for Epidemiologic Studies Depression Scale (CES-D). Physical performance, perceived financial situation, executive functions, loneliness, self-acceptance, and having interests in one's life were studied as explanatory variables. The data were analyzed using cross-sectional bivariate linear modeling. RESULTS: Better physical performance, not perceiving loneliness, having special interests in one's life, and higher self-acceptance were associated with higher life satisfaction and fewer depressive symptoms. Better financial situation was related only to life satisfaction. Executive functions were not associated with either of the outcomes. DISCUSSION: The opposite ends of the same factors underlie positive and negative dimensions of mental well-being. CONCLUSION: Further studies are warranted to better understand how people maintain life satisfaction with aging when many resources may diminish and depressive symptoms become more prevalent.

[Efficacy of Detragel in treatment of varicothrombophlebitis in elderly and aged patients]. / Éffektivnost' detragelia pri lechenii varikotromboflebita u lits pozhilogo i starcheskogo vozrasta.

AIM: The present study was aimed at improving the results of treatment in elderly and aged people by means of local therapy with 'Detragel'. PATIENTS AND METHODS: The authors analysed the results of comprehensive examination and treatment of 60 elderly and aged patients presenting with acute varicothrombophlebitis and severe somatic diseases. Depending on the method of treatment, the patients were subdivided into 2 statistically homogeneous groups consisting of 30 patients each. The patients of both the first and the second group were subjected to crossectomy followed by application of either the 'Lioton' gel or 'Detragel' onto the thrombosed veins for 30 days in Group One and Group Two patients, respectively. Ultrasonographic angioscanning was used to determine dissemination of the thrombotic process in the superficial veins. Before and after the operation we examined the dynamics of the temperature-related and leukocytic reaction, as well as the degree of severity of the oedematous and pain syndromes. Six months after the operation we studied the patients' quality of life using the SF-36 questionnaire. RESULTS: A disseminated form of varicothrombophlebitis was revealed in 35 (58.3%) patients, a local form in 11 (18.3%), and a subtotal one in 9 (15%) patients. The total form with the involvement of the anastomoses of the superficial veins with the deep ones, requiring thrombectomy was detected only in 5 (8.3%) patients and thrombosis of the perforant veins in 3 (5%) patients. Crossectomy made it possible to disrupt the spread of the thrombotic process to the deep veins, with no venous thromboembolic complications registered. Local therapy with Detragel made it possible by POD 7 to normalize both the temperature-related and leukocytic reactions, to relieve the oedematous and pain syndromes, as well as in the remote period to increase the physical health component by 6.42% and the mental health component by 10.21%. CONCLUSION: Local therapy of acute varicothrombophlebitis with Detragel in elderly and aged patients makes it possible to increase the patients' quality of life.

The association between obesity indices and hypertension: Which index is the most notable indicator of hypertension in different age groups stratified by sex?

OBJECTIVE: This study aimed to investigate the most notable obesity index and its optimal cut-off point of hypertension in different age groups stratified by sexes among community residents in southern China. METHODS: In this cross-sectional study, 620 men and 631 women aged 18-59 years were enrolled. The independent-samples t-test and chi-square test were conducted to analyze continuous and categorical variables, respectively. Multivariate logistic regression analysis and receiver operating characteristic (ROC) curve analysis assessed the association between the obesity indices and hypertension risk. RESULTS: Waist-stature ratio (WSR) and waist-hip ratio (WHR) were the most notable risk factors for hypertension in young men and women, respectively. The odds ratios (ORs) of hypertension risk increased with per standard deviation (SD) in WSR and WHR (WSR: OR = 2.877, 95% confidence interval [CI] = 1.602 to 5.167; WHR: OR = 10.683, 95%CI = 2.179 to 52.376). In the middle-aged group of both sexes, body mass index (BMI) was the most distinctive risk factor for hypertension, the ORs of hypertension risk increased with per SD in BMI (men: OR = 2.297, 95%CI = 1.683 to 3.136; women: OR = 1.810, 95%CI = 1.338 to 2.450). ROC curve analysis demonstrated WSR and PI were better indicators than other indices among young men, and WSR was the best marker among young women. However, BMI and WC were the most sensitive markers in middle-aged men and women, respectively. CONCLUSIONS: In this Chinese population, the association of obesity indices and hypertension is inconsistent in different age groups and sexes. It is important to choose appropriate indicators for specific groups of people.

Effects, costs and feasibility of the 'Stay Active at Home' Reablement training programme for home care professionals: study protocol of a cluster randomised controlled trial.

BACKGROUND: According to the principles of Reablement, home care services are meant to be goal-oriented, holistic and person-centred taking into account the capabilities and opportunities of older adults. However, home care services traditionally focus on doing things for older adults rather than with them. To implement Reablement in practice, the 'Stay Active at Home' programme was developed. It is assumed that the programme leads to a reduction in sedentary behaviour in older adults and consequently more cost-effective outcomes in terms of their health and wellbeing. However, this has yet to be proven. METHODS/ DESIGN: A two-group cluster randomised controlled trial with 12 months follow-up will be conducted. Ten nursing teams will be selected, pre-stratified on working area and randomised into an intervention group ('Stay Active at Home') or control group (no training). All nurses of the participating teams are eligible to participate in the study. Older adults and, if applicable, their domestic support workers (DSWs) will be allocated to the intervention or control group as well, based on the allocation of the nursing team. Older adults are eligible to participate, if they: 1) receive homecare services by the selected teams; and 2) are 65 years or older. Older adults will be excluded if they: 1) are terminally ill or bedbound; 2) have serious cognitive or psychological problems; or 3) are unable to communicate in Dutch. DSWs are eligible to participate if they provide services to clients who fulfil the eligibility criteria for older adults. The study consists of an effect evaluation (primary outcome: sedentary behaviour in older adults), an economic evaluation and a process evaluation. Data for the effect and economic evaluation will be collected at baseline and 6 and/or 12 months after baseline using performance-based and self-reported measures. In addition, data from client records will be extracted. A mixed-methods design will be applied for the process evaluation, collecting data of older adults and professionals throughout the study period. DISCUSSION: This study will result in evidence about the effectiveness, cost-effectiveness and feasibility of the 'Stay Active at Home' programme. TRIAL REGISTRATION: ClinicalTrials.gov: NCT03293303 , registered on 20 September 2017.

[Predictive value of serum glycosylated hemoglobin for the onset of nonalcoholic fatty liver disease].

Objective: To discuss the affect of glycosylated hemoglobin (HbA1c) level for the onset of nonalcoholic fatty liver disease (NAFLD) in cohort population. Methods: An epidemiological survey of the relationship between HbA1c and NAFLD conducted in 2012 was based at cohort baseline, and three follow-up sessions conducted in 2013, 2014 and 2015. In total 2 811 subjects were included in the study after exclusion of NAFLD patients at baseline and those who lost their lives due to relocation, and death. The Cox proportional hazard model was used to analyze the relationship between glycosylated hemoglobin and other risk factors of NAFLD. Continuous variables were compared using the t-test or the Mann-Whitney test. χ (2)-test was used for the measurement of categorical data. Results: A total of 2 811 subjects with mean age of 59 (58.2±9.8) years old, including 1 664 males and 1 147 females. Age, waist circumference, body mass index, systolic blood pressure, γ-glutamyltransferase and fasting blood glucose level of HbA1c abnormal group were higher than normal group. The incidence of NAFLD in the abnormal HbA1c level group (25.4%) was higher than normal group (14.9 %), and diastolic blood pressure, high-density lipoprotein cholesterol was lower than normal group and the differences were statistically significant. During the three follow-up intervals, there were 440 new cases of NAFLD, consisting 285 males and 155 females with cumulative incidence of 15.7% (440/2 811). Multivariate Cox regression analysis showed that patients with elevated HbA1c had a higher risk of developing NAFLD (HR 1.796; 95% CI 1.335~2.418; P < 0.01), and the increased HbA1c level after adjustment for gender, age, and metabolic syndrome-related factors remained an independent risk factors for NAFLD (HR 1.580; 95.0% CI 1.161-2.152; P < 0.01). Conclusion: An elevated HbA1c levels have a positive predictive value for the onset of NAFLD.

'Doing with ' rather than 'doing for ' older adults: rationale and content of the 'Stay Active at Home' programme.

BACKGROUND: Owing to increasing age, accidents or periods of illness, home care services are provided to community-dwelling older adults. Traditionally, these services focus on doing things for older adults rather than with them; though from a rehabilitative perspective, it is important to assist older adults to attain and maintain their highest level of functioning. Consequently, a re-orientation of home care services is required away from treating disease and creating dependency towards focusing on capabilities and opportunities and maximising independence. To achieve this behavioural change in home care professionals, the 'Stay Active at Home' programme was developed. AIMS AND METHODS: The aim of this article is to give a detailed description of the rationale and content of the 'Stay Active at Home' programme by making use of the TIDieR (Template for Intervention Description and Replication) Checklist. APPROACH: 'Stay Active at Home' is a comprehensive training programme that aims to equip home care professionals (i.e. community nurses and domestic support workers) with the necessary knowledge, attitude, skills and social and organisational support to deliver day-to-day services at home from a more rehabilitative perspective. More specifically, home care professionals are expected to deliver goal-oriented, holistic and person-centred services focusing on supporting older adults to maintain, gain or restore their competences to engage in physical and daily activities so that they can manage their everyday life as independently as possible.

Smart Homes for Elderly Healthcare-Recent Advances and Research Challenges.

Advancements in medical science and technology, medicine and public health coupled with increased consciousness about nutrition and environmental and personal hygiene have paved the way for the dramatic increase in life expectancy globally in the past several decades. However, increased life expectancy has given rise to an increasing aging population, thus jeopardizing the socio-economic structure of many countries in terms of costs associated with elderly healthcare and wellbeing. In order to cope with the growing need for elderly healthcare services, it is essential to develop affordable, unobtrusive and easy-to-use healthcare solutions. Smart homes, which incorporate environmental and wearable medical sensors, actuators, and modern communication and information technologies, can enable continuous and remote monitoring of elderly health and wellbeing at a low cost. Smart homes may allow the elderly to stay in their comfortable home environments instead of expensive and limited healthcare facilities. Healthcare personnel can also keep track of the overall health condition of the elderly in real-time and provide feedback and support from distant facilities. In this paper, we have presented a comprehensive review on the state-of-the-art research and development in smart home based remote healthcare technologies.

[Association between intestinal flora and immunity in middle-aged and aged people by PCR-DGGE].

OBJECTIVE: To analyze whether the effects of the aging caused changes in intestinal flora to the immunity by evaluating the potent association between the intestinal flora and their immunity of middle-aged and aged healthy subjects based on profiling the composition of their fecal bacteria and testing their immune parameters. METHODS: Total 99 healthy volunteers aged 50- 75 were recruited. Blood samples collected from them were analyzed for CD3~+T cell, CD4~+T cell, CD8~+T cell, serum Ig A, Ig M and Ig G with flow cytometer( FCM) and immunoturbidimetry. The fecal samples were also collected from them. The genomic DNA of fecal bacteria was extracted and amplified with the universal primers of bacterial 16S rRNA V6- V8 region by PCR. The DNA amplifications were tested with denaturing gradient gel electrophoresis( DGGE). Cluster analysis, principal component analysis( PCA) and variance analysis were used to characterize fecal bacteria composition andanalyze the association with observed immune parameters. RESULTS: The fecal microbiota were highly polymorphic and greatly varied among the tested subjects. CD3~+T cell and CD4~+/CD8~+ levels correlated with intestinal flora structure. Intestinal flora richness( S) of population with high CD4~+/ CD8~+ level was lower compared with population with normal or low CD4~+/ CD8~+ level. However, no apparent association was observed between serum Ig A, Ig M, Ig G levels and the fecal microbiota among the tested subjects. CONCLUSION: The decrease in the diversity of intestinal flora might affect CD8~+T cell based innate immunity of host. The deep association could exist between intestinal flora and their immunity in middle-aged and aged people.
