Objective

To describe the association of handgrip strength asymmetry and weakness with cognitive function among Chinese middle-aged and older adults.

Study design

We used data from four waves (2011, 2013, 2015, and 2018) of the China Health and Retirement Longitudinal Study. Handgrip strength was measured at baseline. Handgrip strength asymmetry was defined on the basis of the ratio of handgrip strength of the non-dominant hand to that of the dominant hand (i.e. non-dominant/dominant): a ratio of <0.9 defined as dominant handgrip strength asymmetry and >1.1 as non-dominant handgrip strength asymmetry. Weakness was defined as a handgrip strength of <28 kg for males or <18 kg for females.

Main outcome measures

Cognitive function with its two core dimensions (episodic memory and mental status) at each wave was assessed and standardized.

Results

9333 participants (48.3 % female, age 58.2 ± 9.0 years) were included. Non-dominant but not dominant handgrip strength asymmetry was significantly associated with poorer cognitive function at baseline (β = −0.121, −0.092, and −0.132 for mental status, episodic memory, and global cognition, respectively). In longitudinal analyses over 2 years, dominant handgrip strength asymmetry significantly slowed cognitive decline (β = −0.078 and −0.069 for mental status and global cognition, respectively), and non-dominant handgrip strength asymmetry accelerated cognitive decline (β = 0.053 and 0.043 for episodic memory and global cognition, respectively). Weakness was associated with poorer cognitive function at baseline and cognitive decline over 2, 4, and 7 years (all P < 0.05).

Conclusions

In middle-aged and older adults, non-dominant handgrip strength asymmetry and weakness were associated with poorer cognitive function and predicted accelerated cognitive decline. Dominant handgrip strength asymmetry may be beneficial for maintaining cognitive function.

Objective

Worsening of sleep quality during menopause is well recognized. However, the underlying hormonal regulation is insufficiently described. In this study, we evaluated associations between sleep and cortisol levels.

Study design

Seventeen perimenopausal and 18 postmenopausal women were enrolled in a three-night sleep study. Diurnal blood sampling was performed during the third night and the following day.

Main outcome measures

Self-reported insomnia and sleepiness were evaluated with the Basic Nordic Sleep Questionnaire and sleep architecture with all-night polysomnography. Diurnal cortisol samples were collected at 20-min intervals. Correlation analyses and generalized linear models adjusted by age, body mass index, vasomotor symptoms and depressive symptoms were conducted.

Results

In correlation analyses, self-reported insomnia and sleepiness were not associated with cortisol levels. Lower sleep efficiency, slow-wave sleep and stage 1 percentages, number of slow-wave sleep and of rapid-eye-movement (REM) periods, longer slow-wave sleep latency and higher wake after sleep onset percentage were associated with higher cortisol levels (all p < 0.05). Further, lower slow-wave sleep percentage and longer slow-wave sleep latency correlated with steeper daytime cortisol slope (i.e. day cortisol decrease, both p < 0.05). In adjusted generalized linear models, lower sleep efficiency and number of rapid-eye-movement periods as well as higher wake after sleep onset percentage correlated with higher cortisol levels; lower slow-wave sleep percentage correlated with higher cortisol awakening response.

Conclusions

Worse sleep architecture but not worse self-reported insomnia and sleepiness was associated with higher cortisol levels. This is important for understanding sleep in women, especially during the menopausal period.

Objectives

To explore relationships between ‘need for recovery’ (NFR), a strong predictor of burnout, and menopause symptoms and to identify work-related factors that are associated with a high NFR in Belgian menopausal women.

Study design

760 menopausal women took part in a cross-sectional questionnaire study. NFR, presence of menopause symptoms, job type, age category, work activity, physical workload, psychosocial and physical work environment, balance of work and private life and the opportunity to discuss menopause at work were assessed.

Main outcome measures

Uni- and multivariate logistic regression analyses were used to calculate the odds ratios for the presence of a high NFR.

Results

Of menopausal women currently experiencing menopause symptoms, 53.3 % reported problems while performing their work. The overall prevalence of a high NFR in menopausal women was 41.2 %. Women who experienced problems at work had the highest prevalence of a high NFR (61.1 %), and constituted a separate risk group for having a high NFR (OR 3.31 vs. never symptoms; 95%CI 1.72–6.38). The following factors were significantly associated with a high NFR: poor balance of work and private life (OR 7.89; 95%CI 4.32–14.39), physical workload (OR 1.17; 95%CI 1.08–1.28), discomfort from cognitive demands (OR 1.17; 95%CI 1.09–1.26), organizational justice (OR 0.86; 95%CI; 0.78–0.94), and social support from colleagues (OR 0.87; 95%CI 0.79–0.96).

Conclusions

Maintaining a good balance of work and private life, reducing physical workload, addressing discomfort from cognitive work demands and assuring a fair work distribution are measures that require a culture where open and easy discussion about menopause is possible.

Background

Overactive bladder (OAB) is a common condition in middle-aged and older women. It has been reported to be potentially linked to cognitive decline, particularly in older adults. This study investigated the association between OAB symptoms and cognitive impairment in middle-aged women.

Materials and methods

This cross-sectional study had a sample of 1652 women (mean age 49.3 ± 2.8 years) who were not taking medication for either urinary tract infection or OAB. OAB symptoms and cognitive function were evaluated by self-administered questionnaires: the Overactive Bladder Symptom Score and the Alzheimer's disease 8. Logistic regression models estimated prevalence ratios (PRs) with 95 % confidence intervals (CI) for cognitive impairment according to the presence/absence of OAB. Mediation analyses assessed the impact of poor sleep quality on this association.

Results

Cognitive impairment was more prevalent in women with OAB than in those without OAB (multivariable-adjusted PR: 1.88 [95 % CI: 1.52–2.24]). Women experiencing nocturia (≥twice a night), urinary urgency at least once a week, and urgency urinary incontinence at least once a week had multivariable-adjusted PRs (95 % CI) for cognitive impairment of 2.08 (1.50–2.65), 2.12 (1.66–2.58), and 1.75 (1.17–2.34), respectively. Poor sleep quality mediated 10.81 % [95 % CI: 4.55–19.44 %] of the relationship between OAB and cognitive impairment.

Conclusions

Among middle-aged women not taking OAB medications, OAB symptoms were associated with cognitive impairment, partly because of poor sleep quality. Further research is needed to determine whether early screening of patients with OAB can help identify those susceptible to cognitive impairment associated with OAB medication and if preventive measures should be targeted at this group.

For women under age 65, varying recommendations and the need to apply clinical risk calculators can lead to underscreening for osteoporosis. The resulting undertreatment may lead to a risk of osteoporotic fractures with significant morbidity and impact on functional status. Factors that must be considered when deciding to screen a woman under age 65 include a history of fragility fractures, race, family history, body mass index, smoking, high alcohol use, and secondary causes of osteoporosis. Secondary causes of osteoporosis are much more common in younger women. These include common conditions such as glucocorticoid use, hyperthyroidism, hypogonadism, chronic kidney disease, diabetes, anticonvulsant use, rheumatoid arthritis, malabsorption, and a history of anorexia nervosa. The reasons why these conditions confer an increased risk of osteoporosis are discussed. Recommendations are provided for the clinician to be aware of when screening women under age 65 for osteoporosis and initiating treatment when indicated.

Globalization and international migration movements have massively changed the population structure of most industrial nations in recent decades. The ever-increasing proportion of people with a migration background also poses a challenge for the medical sector. A particular problem is the stressful phase of the menopausal transition, which - although not a pathological phenomenon but part of the female life history - can lead to psychological and physical symptoms due to hormonal changes, which significantly impair the quality of life of the women affected. However, treatment concepts, as well as access to medical facilities and information, are geared towards Western women from high-income countries. Women with a history of voluntary or forced migration originating from non-Western countries represent a particularly vulnerable group. To enable personalized treatment, studies on menopausal transition in women with a migration background are required. The present review shows that studies on menopausal women with a migration background have been conducted primarily in classic immigration countries such as the USA, Australia, or the UK, but that there is a lack of such studies in countries with no long tradition as an immigration country, such as Austria or Germany. This is becoming a growing problem, as the number of menopausal women with a migration background is increasing.

Acupoint-stimulating therapies have often been used to manage stroke-related spasticity and motor dysfunction. However, the effects of different acupoint-stimulating therapies in older stroke survivors have been unclear. This systematic review and network meta-analysis compared the effects of different acupoint-stimulating therapies in managing spasticity and motor dysfunction in older stroke survivors. The study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched 7 databases for studies published up to July 2023. Inclusion criteria were: (1) older adults with strokes; (2) treatments were acupoint-stimulating therapies; (3) a control group did not receive acupoint-stimulating therapy, or the study compared different acupoint-stimulating therapies; and (4) outcomes included spasticity and motor function. Methodological quality was assessed with Risk-of-bias tool for randomized trials version 2, while R and Metainsight were used to conduct the network meta-analysis. We analyzed 27 studies and the results showed that non-invasive electroacupuncture and warm acupuncture were more effective in reducing spasticity than conventional acupuncture (standardized mean difference and 95 % confidence intervals = 1.35/1.19 [0.57; 2.13/0.54; 1.83]) and invasive electroacupuncture (standardized mean difference and 95 % confidence intervals = 0.96/0.80 [0.12; 1.80/0.08; 1.51]). Conventional acupuncture and invasive electroacupuncture were effective in improving motor function (standardized mean difference and 95 % confidence intervals = 0.99/1.41 [0.42; 1.56/0.54; 2.28]). However, there was significant inconsistency for the effects of invasive electroacupuncture between studies. Our findings suggest that for older stroke survivors with spasticity, non-invasive electroacupuncture and warm acupuncture are appropriate, whereas conventional acupuncture is more appropriate for patients aiming for motor recovery.

Systematic review registration

This study was registered in the PROSPERO database (CRD42023442202).

Objectives

This study aimed to characterize African American women's experiences of menopause and their interactions with the health care system related to menopausal symptoms.

Study design

We conducted four focus groups with community-dwelling midlife African American women.

Main outcomes measures

Women who consented to participate completed demographic surveys. Transcripts of the four focus groups (n = 26) were analyzed and themes were elucidated.

Results

In total, 26 midlife African American women participated in the four focus groups. Participants revealed unmet needs regarding obtaining menopause information from their clinicians. Clinician discussions about menopause tended to be initiated by patients based on their symptoms. Some women reported feeling ignored and/or dismissed by the clinician when they initiated discussions of menopause. Women wanted their clinicians to provide information on menopause, which included receiving information prior to the menopause transition to help them know what to expect.

Conclusion

Women wanted their clinicians to initiate discussions of menopause rather than wait for women to mention symptoms. Prioritizing menopause training for clinicians taking care of midlife African American women may help to improve discussions of menopause.

Objective

The aim of this study was to examine associations between empirically derived dietary pattern scores and cognition, as well as risk of cognitive decline, over an average of 4.6 (± 0.3) years in older men.

Materials and methods

This analysis was conducted as part of the Osteoporotic Fractures in Men (MrOS) prospective cohort study. Diet was assessed at Visit 1 (3/2000–4/2002) by food frequency questionnaire, and dietary patterns (Western and Prudent) were derived by factor analysis. The analytic cohort comprised 4231 community-dwelling American men who were aged 65 years or more. Cognitive function was assessed with the Modified Mini-Mental State exam (3MS) and the Trails B test at Visit 1 and at Visit 2 (3/2005–5/2006). Associations between dietary pattern score and cognition and risk of cognitive decline were estimated using mixed effects regression models. Model 1 was adjusted for age, clinic site and total energy intake (TEI). Model 2 was further adjusted for calcium and vitamin D supplement use, body mass index (BMI), physical activity, smoking, diabetes and hypertension (Western diet group) and education, calcium and vitamin D supplement use, depression, BMI, physical activity, smoking and stroke (Prudent diet group).

Results

Adherence to the Western dietary pattern was associated with higher 3MS scores and shorter Trails B test time at Visit 1 in Model 2. Adherence to the Prudent dietary pattern was associated with higher 3MS scores in Model 1 but not Model 2. There were no independent associations between dietary pattern scores and risk of cognitive decline 4.6 (± 0.3) years later at Visit 2.

Conclusion

The results do not support a robust protective effect of the Prudent dietary pattern on cognition in the MrOS cohort. Associations between the Western dietary pattern and better cognitive scores should be interpreted with caution. Further research is needed to understand the complex interactions between dietary patterns and cognition in older men.

Objectives

There is no precedent for the use of social media in preventing sarcopenia. The aim of this study is to develop a social media-based intervention programme for the young-old population in the community in China to improve their awareness and behaviours regarding sarcopenia prevention.

Study design

Using guidelines for developing complex interventions, this study was divided into two main phases: a co-development phase and a preliminary test phase. Both were carried out in Changsha, China. The development phase employed co-design methodology with relevant stakeholders, including two rounds of consultation with patient and public involvement (12 members) and two rounds of focus groups (30 participants); this was followed by the three-week preliminary test phase (22 participants).

Main outcome measures

This study evaluated the consultation with patient and public involvement, and mainly collected qualitative data from the two rounds of focus group interviews and a final semi-structured interview following the preliminary test, so as to explore the participants' experiences, comments, and suggestions for revising the social media-based intervention. Handgrip strength was also evaluated.

Results

The health education included seven videos of 4–6 min each related to sarcopenia, including information on the concept, influencing factors, adverse effects, manifestations, screening methods, and preventions. The exercise video consisted of four types of training (warm-up, aerobic, resistance, and flexibility training) and lasted 30 min, with a suggested engagement of at least 3 days/week. The specific contents and “dosage” of the final intervention were unanimously favourable to the diverse stakeholders involved (older adults with possible sarcopenia, experts, researchers). After the preliminary test, an improvement in handgrip strength was observed, from M15.92$\pm \mathrm{SD}$5.22 kg to M19.13$\pm \mathrm{SD}$5.44 kg (T = −5.44, P < 0.001). Subgroup analysis revealed that this improvement was evident in both men and women.

Conclusions

The social media-based intervention was universally endorsed by the participants and showed indications of a positive influence on sarcopenia. A feasibility study is now needed.
