The blood pressure control effect of the sodium-restricted dietary approaches to stop hypertension diet: a systematic review.

The Dietary Approaches to Stop Hypertension (DASH) diet is highly effective in controlling blood pressure (BP). Although Na restriction is not a primary focus within the DASH diet, it is recommended that it be added to control BP. Therefore, we aimed to systematically review the characteristics and BP-lowering effects of Na-restricted DASH diet interventions. We searched thirteen databases, namely, MEDLINE, Embase, Cochrane Central Register of Controlled Trials, KoreaMed, KISS, KMbase, RISS, CINAHL, Scopus, ClinicalTrials.gov, Grey Literature Report, OpenGrey and PQDT Global, for articles published through May 2023. The randomised controlled trials assessing the BP-lowering effect of the Na-restricted DASH diet in adults aged 18 years and older were included. The study protocol was registered in the PROSPERO registry (CRD42023409996). The risk of bias in the included studies was also assessed. Nine articles were included in this review. Interventions were categorised into three types: feeding, provision and education, and the study results were compared by intervention type. BP was significantly reduced in two of the three feeding studies, one of the three provisional studies and none of the educational studies. In eight studies, effect sizes varied among both systolic BP (-7·7 to -2·4) and diastolic BP (-8·3 to 0·1). Six studies showed an overall high risk of bias. In conclusion, Na-restricted DASH may have beneficial effects on BP control. Additionally, compared with control interventions, feeding interventions appeared to have a greater BP-lowering effect. Further high-quality studies are needed to improve the quality of the evidence.

The relationship between self-reported sensory decline and cognitive frailty in older persons.

This study aimed to explore the relationship between self-reported sensory decline, including poor hearing and vision, and cognitive frailty in older persons. This cross-sectional study analyzed data from the 2020 National Survey of Living Conditions and Welfare Needs of Older Koreans. Binomial logistic regression analysis was performed to analyze the relationship between self-reported sensory decline and cognitive frailty. Of 9,692 participants, 39.8 % experienced sensory decline. The prevalence of cognitive frailty was 15.7 % among participants with poor hearing, 6.9 % among those with poor vision, and 17.9 % among those with combined poor hearing and vision. In our model, adjusted for sociodemographic and health-related variables, the cognitive frailty was significantly associated with poor hearing alone and combined poor hearing and vision. The findings suggest that healthcare professionals should prioritize their attention to the risk of cognitive frailty in older adults experiencing poor hearing alone and combined with poor vision.

Silent struggles to self-manage high blood pressure among deaf sign language users: a qualitative study.

AIMS: Tailored self-management support of hypertension, considering language and communication, is important for minorities, specifically in the deaf community. However, little is known about the experiences of hypertension self-management in deaf individuals who use sign language. This study aimed to explore the factors and processes of self-management in deaf sign language users with hypertension. METHODS AND RESULTS: Ten men and women who used sign language participated in this study. Data were collected using in-depth personal interviews conducted in the presence of a sign language interpreter between November 2022 and February 2023. All interviews were recorded and transcribed for conventional content analysis. Qualitative analyses identified four categories related to the self-management of hypertension among participants: personal factors (chronic hand pain, unique language and communication, and efforts to turn crisis into opportunities), family and socioeconomic factors (family support and financial burden of living), challenges (limited health literacy and alienation from health education), and desire for health education considering the deaf community. CONCLUSION: The results of this study suggest that family support, socioeconomic status, hand pain, and health literacy should be considered for the planning and development of health education on self-management of hypertension in deaf individuals. In addition, this health education requires cooperation with qualified sign language interpreters in healthcare settings.

Associations with smartphone usage and life satisfaction among older adults: Mediating roles of depressive symptoms and cognitive function.

This study aimed to investigate the serial mediating effects of depressive symptoms and cognitive function on the relationship between smartphone usage and life satisfaction among older people. Multiple linear regression analyses for complex randomly sampled data were used to identify the association between the status/level of smartphone usage, depressive symptoms, cognitive function, and life satisfaction. Furthermore, the Sobel test was conducted to assess the serial mediating effects of depressive symptoms and cognitive function on the relationship between smartphone usage and life satisfaction. The status and level of smartphone usage had significant positive impacts on cognitive function and life satisfaction, and negative impacts on depressive symptoms. Our results suggest that nurses should assess the status and level of smartphone usage among older people and plan approaches that enable them to utilize various smartphone functions to improve the well-being of this population.

Understanding health literacy of deaf persons with hypertension in South Korea: A cross-sectional study.

BACKGROUND: Health literacy is strongly associated with health inequality among persons with deafness, and hypertension (HTN) is the most prevalent chronic disease among persons with deafness in South Korea. Despite its importance, research regarding the health literacy levels of persons with deafness with HTN in South Korea is lacking. This study aimed to comprehensively assess the health literacy levels of persons with deafness with HTN in South Korea, including linguistic, functional, and internet health literacy. METHODS: In this descriptive cross-sectional study, 95 persons with deafness with HTN were recruited through facilities associated with the deaf community. From August 2022 to February 2023, data were collected through face-to-face surveys attended by a sign language interpreter and online surveys. The data were analyzed using descriptive statistics and Spearman's correlation. RESULTS: Approximately 62.1% of the participants exhibited a linguistic health literacy level corresponding to less than that of middle school students, and the total percentage correct of functional health literacy was 17.9%. Each domain of internet health literacy was low. Significant correlations were found between some aspects of health literacy. CONCLUSIONS: The study's findings highlight the low health literacy levels across various facets among persons with deafness with HTN in South Korea. Based on these findings, several strategies are suggested for developing HTN self-management interventions for persons with deafness. This study contributes to the foundational understanding of health literacy among persons with deafness with HTN in South Korea and provides valuable insights and guidance for developing HTN self-management interventions.

Similarities and Differences of Interventions to Promote Physical and Psychological Health Between Prefrail and Frail Older Women: A Systematic Review.

The current review aimed to explore similarities and differences in the properties of interventions that promote physical and psychological health between prefrail and frail older women. Ten databases were searched for studies published from database inception to May 2023. Two Cochrane tools were used to assess the risk of bias in experimental and quasi-experimental studies. Twenty-three studies were selected, including 11 studies on prefrailty and 12 studies on frailty. Exercise interventions were predominant, but the contents and standards of exercise intensity were inconsistent between prefrail and frail women. For the main outcomes of the interventions, balance ability and biochemical factors were measured more frequently for frail older women than prefrail older women. Psychological health was less measured for prefrail and frail older women compared to physical health. Future research needs to consider balance training, as well as the evaluation of biochemical factors and psychological health among prefrail or frail older women.

Association Between Social Frailty and Life Satisfaction Among Older Adults: The Role of Functional Limitations and Depressive Symptoms.

The current study aimed to identify life satisfaction depending on the degree of social frailty and explore the mediating role of functional limitations and depressive symptoms between social frailty and life satisfaction. A secondary analysis of a cross-sectional survey was used. Data of 6,479 older adults were selected from the 2020 National Survey of Older Koreans. Of all participants, 2,595 (40.1%) and 1,605 (24.8%) had social prefrailty and frailty, respectively. Life satisfaction of participants with social frailty was significantly worse than those without social frailty. Social frailty negatively influenced life satisfaction. Functional limitations and depressive symptoms serially mediated the association between social frailty and life satisfaction. This mediation model provided evidence of the associations among social frailty, functional limitations, depressive symptoms, and life satisfaction in older adults. In community care settings, nurses should recognize the assessment of social frailty to enhance the subjective well-being of older adults. [Research in Gerontological Nursing, 16(6), 291-300.].

Chronic disease interventions for people with visual impairment: A systematic review.

AIM: To identify the characteristics of chronic disease interventions for people with visual impairment (PVI) and provide suggestions for future interventions. BACKGROUND: Chronic diseases are more common in PVI than people without visual impairment, and PVI have difficulty managing chronic diseases due to physical, social, and psychological problems associated with visual impairment. However, evidence regarding chronic disease intervention for PVI is limited. METHODS: This review was guided by the PRISMA methodology. Data were extracted and checked, and each study was evaluated to ensure their methodological quality using appropriate tools based on the study design. Findings were described through a qualitative synthesis, and the above process was carried out by all four researchers. RESULTS: 28 studies were selected. The intervention for mental disorders was the most common with about 39.3%, followed by stroke (25.0%), diabetes (17.8%), various chronic diseases (10.7%), chronic pain (3.6%), and scoliosis (3.6%). Most of the intervention was delivered individually, and the place of intervention often depends on the preference or convenience of PVI. A wide range of intervention materials was used, from large print, audio, or braille version reading materials to technology products. Based on the results, the main areas of the outcomes were daily living function, psychological conditions, and quality of life. CONCLUSIONS: This review identified the components of interventions for PVI and provided intervention strategies. In particular, chronic disease interventions for PVI should be planned by considering how and where appropriate interventions are provided, various available materials, and the problems to be addressed.

Water extract of tendril of Cucurbita Moschata Duch. suppresses RANKL-induced osteoclastogenesis by down-regulating p38 and ERK signaling.

Background: Pumpkin (Curcubita sp.) is a natural product that is commonly used in folk medicine. However, the inhibitory effect and molecular mechanisms of tendril of Cucurbita Moschata Duch. (TCMD) on osteoclast differentiation have yet to be clearly elucidated. Thus, the present study aimed to investigate the effect and underlying mechanism of water extract of TCMD on osteoclast differentiation. Methods: Bone marrow-derived macrophages (BMDMs), osteoclast precursors, were cultured with macrophage colony stimulating factor (M-CSF) 30 ng/ml and receptor activator of nuclear factor-kappa B ligand (RANKL) 100 ng/ml for four days. We investigated the effect of TCMD on RANKL-induced osteoclast differentiation, tartrate-resistant acid phosphatase (TRAP) staining, F-actin ring formation, and bone resorption assay. RANKL signaling pathways were determined through Western blotting, and osteoclast differentiation marker genes were confirmed by Real-time PCR. Results: TCMD inhibited the RANKL-induced osteoclast differentiation in a dose-dependent manner without cytotoxicity. Further, F-actin ring formation and bone resorption were reduced by TCMD in RANKL-treated BMDMs. In addition, TCMD decreased the phosphorylation of p38 and ERK as well as the expression of osteoclast-related genes in BMDMs treated with RANKL. Conclusion: These findings suggest that TCMD may have preventive and therapeutic effects for destructive bone diseases.

Combination of mineral trioxide aggregate and propolis promotes odontoblastic differentiation of human dental pulp stem cells through ERK signaling pathway.

The aim of this study is to investigate combined effects of mineral trioxide aggregate (MTA) and propolis on odontoblastic differentiation of human dental pulp stem cells (DPSCs) and to find a signaling pathway involved. Combination of MTA and propolis significantly up-regulated the expression of DSPP and DMP1, and facilitated a mineral nodule formation (p < 0.05). Treatments with MTA, propolis or combined increased the phosphorylation of extracellular signal-regulated kinases (ERK), one of mitogen-activated protein kinases signaling cascades during odontogenic differentiation of DPSCs (p < 0.05), and U0126, an inhibitor of ERK, decreased calcium deposits (p < 0.05). Combination of MTA and propolis promotes odontogenic differentiation and mineralization of DPSCs through ERK pathway.
