Background: Body mass index (BMI) of patients with ischemic stroke (IS) has been associated with prognosis and disability in studies in the United States. Although the Asian population is leaner, the optimal BMI for stroke-related disability remains unknown., Objectives: To clarify the association between BMI and disability in patients with IS from a national database in Japan., Methods: The present study included 522,421 patients with IS identified in the JROAD-DPC database from April 2016 to March 2020. We used the WHO classification of BMI, which divides Asia-Pacific patients into five groups, to categorize BMI and the modified Rankin Scale (mRS) to assess stroke-related disability at admission and discharge. After multiple imputation for missing values, we conducted a multiple mixed-effect logistic regression analysis for poor mRS score (>2) in September 2023. In addition, we created a restricted cubic spline model between the odds ratio (OR) for poor mRS and BMI., Results: The mRS score worsened during hospitalization in 60.1% of the patients with IS, and 45.7% had a poor mRS score at discharge. Overweight patients had the lowest OR of having a poor mRS score (OR: 0.898, 95% confidence interval: 0.895-0.902). The spline curve for the OR for poor mRS score was U-shaped with a BMI of 24.7 kg/m 2 as the apex value., Conclusion: The present study revealed a U-shaped relationship between BMI and stroke-related disability, with overweight patients having the lowest OR for disability at discharge.

This study aimed to investigate the rate of sedentary behaviour and differences in physical outcomes and activities of daily living (ADL) based on sedentary behaviour time of hospitalized older cardiovascular disease patients undergoing phase I cardiac rehabilitation. Older cardiovascular disease patients were enrolled from October 2020 to September 2023 and were divided into the high sedentary behaviour group (≥ 480 min/day) and low sedentary behaviour group (< 480 min/day). Patients' clinical characteristics, usual gait speed, and Five Times Sit to Stand Test time were compared as indices of physical outcomes. Motor, cognitive, and total Functional Independence Measure (FIM) scores were used as indices of ADL and compared between groups using analysis of covariance. Final analysis included 402 patients (mean age: 76.7 years, female: 35.3%). The high sedentary behaviour group included 48.5% of the study patients. After adjustment for baseline characteristics, gait speed (0.80 ± 0.27 vs. 0.96 ± 0.23 m/s, p < 0.001) was lower and FTSST time (11.31 ± 4.19 vs. 9.39 ± 3.11 s, p < 0.001) was higher in the high sedentary behaviour group versus low sedentary behaviour group. Motor (85.82 ± 8.82 vs. 88.09 ± 5.04 points, p < 0.001), cognitive (33.32 ± 2.93 vs. 34.04 ± 2.24 points, p < 0.001), and total FIM scores (119.13 ± 10.66 vs. 122.02 ± 6.30 points, p < 0.001) were significantly lower in the high sedentary behaviour group versus low sedentary behaviour group after adjustment. In older cardiovascular disease patients in phase I cardiac rehabilitation, sedentary behaviour time might influence physical outcomes and ADL at discharge. It is thus important to consider the amount of sedentary behaviour time spent by these patients during daily life while hospitalized., (© 2024. The Author(s).)

Background: Construction of an intervention method for the cognitive dysfunction of patients with acute coronary syndrome (ACS) is needed. Exercise-based comprehensive cardiac rehabilitation is a potentially effective approach that can improve cognitive function in ACS patients. This study aimed to investigate the effect of cardiac rehabilitation on cognitive function in ACS patients through a systematic review., Methods: A systematic review was conducted of studies on PubMed, MEDLINE, Web of Science, and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) on September 13, 2022, to identify those reporting the effects of cardiac rehabilitation on cognitive function in ACS patients. Data that reported exercise-based comprehensive cardiac rehabilitation and cognitive function (even if not main results and any type of cognitive function assessment was used) were extracted., Results: In total, six studies were included that comprised a total of 1085 ACS patients. Overall positive effects of cardiac rehabilitation on cognitive function in ACS patients were reported across the six studies. All studies included aerobic exercise, resistance exercise, and patient education in cardiac rehabilitation. Meta-analysis could not be undertaken because each dataset used different methods to evaluate cognitive function, and the outcomes were different., Conclusions: This systematic review showed that cardiac rehabilitation could have positive effects on cognitive function in ACS patients. Our results support the efficacy of cardiac rehabilitation for cognitive function in ACS patients. Additional well-designed clinical trials of exercise-based comprehensive cardiac rehabilitation should be conducted to clarify the true effect on cognitive function in ACS patients., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2024 The Authors.)

Pregnant women are encouraged to reduce sitting time and replace it with physical activity. Complications arising during pregnancy include gestational hypertension, preeclampsia, gestational diabetes mellitus (GDM), and prenatal and postpartum depression. In this systematic review, we examined effects of sedentary behavior on the health of pregnant women. We conducted a systematic review with PubMed from year 2000 to identify the relationship between a sedentary lifestyle and psychological effects, occurrence of GDM, gestational hypertension, and preeclampsia. Data extracted included sedentary time of pregnant women, psychological effects, occurrence of GDM, gestational hypertension, and preeclampsia as outcomes. Among the 200 studies retrieved, 11 were finally included after screening. The mean age of eligible pregnant women ranged from 28.5 to 32.9 years. Five studies were extracted with outcomes of psychological effects on the mother, five with GDM, and one with gestational hypertension/preeclampsia. Longer sedentary time was associated with increased risks of prepartum/postpartum depression in three of five studies and GDM in three of five studies. No association was found between sedentary behavior and the risk for gestational hypertension/preeclampsia. Higher sedentary behavior in the second trimester of pregnancy was likely to be associated with postpartum depression. Longer sitting time may increase the risk of prenatal or postnatal depression and GDM, but no relationship was proven for gestational hypertension and preeclampsia in one study. High sedentary behavior in the second trimester may have psychological impacts. The number of studies was small and further research is needed to statistically evaluate impacts of sedentary behavior during pregnancy., (© 2023.

Health literacy (HL) is an important decision factor for health. Both low HL and low physical function cause adverse events in cardiovascular disease patients, but their relationship is not well documented. To clarify the relationship between HL and physical function of patients participating in cardiac rehabilitation and calculate the cutoff value of the 14-item HL scale (HLS) for low handgrip strength, this multicenter clinical study named the Kobe-Cardiac Rehabilitation project for people around the World (K-CREW) was conducted among four affiliated hospitals with patients who underwent cardiac rehabilitation. We used the 14-item HLS to assess HL, and the main outcomes were handgrip strength and Short Physical Performance Battery (SPPB) score. The study included 167 cardiac rehabilitation patients with a mean age of 70.5 ± 12.8 years, and the ratio of males was 74%. Among them, 90 patients (53.9%) had low HL and scored significantly lower in both handgrip strength and SPPB. Multiple linear regression analysis revealed that HL was a determinant factor (β = 0.118, p = 0.04) for handgrip strength. Receiver operating characteristic analysis revealed the cutoff value of the 14-item HLS for screening for low handgrip strength was 47.0 points, and the area under the curve was 0.73. This study showed that HL was significantly associated with handgrip strength and SPPB in cardiac rehabilitation patients and suggests the possibility of early screening for low HL to improve physical function in cardiac rehabilitation patients with low HL., (© 2023.

Increased sedentary behaviour (SB) is reportedly associated with mortality and morbidity in cardiovascular disease. However, its relation with physical function is not well understood in phase I cardiac rehabilitation (CR). This study aimed to investigate the rate of SB and the relation between SB and physical function among patients participating in phase I CR. This prospective multicentre cohort study enrolled patients participating in CR from October 2020 to July 2022. Patients with probable dementia and difficulty walking alone were excluded. We used sitting SB time as the index of SB and the Short Performance Physical Battery (SPPB) as the index of physical function at discharge. Patients were divided into the low SB group (< 480 min/day) or high SB group (≥ 480 min/day). We analysed and compared the two groups. The final analysis included 353 patients (mean age: 69.6 years, male: 75.6%), of whom 47.6% (168 of 353) were high SB patients. Total sitting SB time was higher in the high SB group versus the low SB group (733.6 ± 155.3 vs 246.4 ± 127.4 min/day, p < 0.001), and mean SPPB score was lower in the high SB group versus the low SB group (10.5 ± 2.4 vs 11.2 ± 1.6 points, p = 0.001). Multiple regression analysis identified SB as an explanatory variable for total SPPB score (p = 0.017). Patients with high SB had significantly lower SPPB scores than those with low SB. These findings underscore the importance of considering SB when improving physical function. Effective strategies to improve physical function can be developed that consider SB in phase I CR., (© 2023. The Author(s).)

Various studies have shown the effectiveness of motor interventions for children with neurodevelopmental disorders (NDDs). Web-based interventions may provide an opportunity for remote access to effective interventions with less burden on therapists. This systematic review aimed to examine the effects of web-based exercise interventions for children with NDDs. We searched PubMed for relevant articles published in English since 1994 and included intervention studies focusing on NDDs in children aged ≤18 years, who received web-based exercise interventions. We categorized the extracted information by outcome measure and intervention type and assessed the risk of bias of the included studies. We selected five articles whose subjects had autism spectrum disorder (ASD), attention deficit hyperactivity disorder (ADHD), and developmental coordination disorder (DCD). The exercise interventions used active video games, a Zoom-based intervention, and a WhatsApp-based intervention. Three papers showed improvements in physical activity, motor function, and executive function, whereas two papers on DCD showed no improvements in motor coordination or physical activity. Web-based exercise intervention for children with ASD and ADHD may improve their motor function, executive function, and physical activity rather than for children with NDDs. An intervention may be more effective when the content of the intervention is based on objectives and symptoms, when guidance is provided by specialists, or when sufficient explanation and support are provided to parents. However, more research is needed to statistically evaluate the effectiveness of web-based exercise interventions for children with NDDs.

The activities of daily living (ADL) in patients with cardiac disease tend to decline. A previous study revealed that ADL relates to physical and cognitive functions associated with health literacy (HL). However, the relationship between HL and ADL is not well documented. This study aimed to clarify this relationship among patients participating in cardiac rehabilitation. This multicenter study, the Kobe-Cardiac Rehabilitation project for people around the World (K-CREW), included patients who participated in cardiac rehabilitation from October 2020 to December 2021. Patients with probable dementia and difficulty walking alone were excluded. We used the 14-item Health Literacy Scale (HLS-14) to assess HL and the Functional Independence Measure (FIM) to assess ADL at discharge. Patients were divided by their HLS-14 score into the low HL group (<50 points) or the high HL group (≥50 points). We analyzed the relationship between the HLS-14 and FIM scores. We investigated 268 cardiac rehabilitation patients (median age, 71.0 years; male ratio, 76.9%). Low HL patients accounted for 51.1% of all patients and had significantly lower motor and cognitive FIM scores. Functional HL related better to the FIM scores (r = 0.28-0.36) than did other HL subclasses. Multiple regression analysis identified HLS-14 as an explanatory variable ( p = 0.002) for the total FIM score. Patients with low HL had significantly lower ADL than those with high HL. These findings underscore the importance of considering HL in cardiac rehabilitation.

Background: The impact of body mass index (BMI) on hospital mortality in patients with acute heart failure has been well documented in Asian populations. However, the relationship between BMI, hospital-associated disability (HAD), and hospitalization costs in patients with heart failure is poorly understood. This study aimed to explore the impact of BMI on HAD and hospitalization costs for acute heart failure in Japan., Methods: From April 2012 to March 2020, the Japanese Registry of All Cardiac and Vascular Disease Diagnosis Procedure Combination (JROAD-DPC) database was used to identify patients with acute heart failure. All patients were categorized into five groups according to the World Health Organization Asian BMI criteria. The hospitalization costs and HAD were evaluated., Results: Among the 238,160 eligible patients, 15.7% were underweight, 42.2% were normal, 16.7% were overweight, 19.3% were obese I, and 6.0% were obese II, according to BMI. The prevalence of HAD was 7.43% in the total cohort, and the risk of HAD increased with a lower BMI. Restricted cubic spline analysis showed a U-shaped relationship between BMI and hospitalization costs for all ages. Furthermore, developing HAD was associated with greater costs compared with non-HAD, regardless of BMI category., Conclusions: We found that the lower the BMI, the higher the incidence of HAD. A U-shaped association was confirmed between BMI and hospitalization costs, indicating that hospitalization costs increased for both lower and higher BMI regardless of age. BMI could be an important and informative risk stratification tool for functional outcomes and economic burdens., Competing Interests: Declaration of Competing Interest None., (Copyright © 2022.

Objective: To clarify the impacts of health literacy on mortality, readmission, and quality of life (QOL) in the secondary or tertiary prevention of cardiovascular diseases (CVD) through a meta-analysis., Methods: Six electronic databases were searched on June 11, 2020. Observational studies involving patients with CVD, health literacy as an exposure factor and mortality, readmission, or QOL as outcomes were included in this study. Two researchers screened the retrieved articles and extracted data independently. The meta-analysis calculated the pooled relative risk of mortality and readmission. We also assessed the body of evidence based on Grading of Recommendations Assessment, Development and Evaluation (GRADE)., Results: Following screening of 1616 studies, 16 observational studies were included. The mean rate of low health literacy was 32.8%. All studies focusing on QOL showed significant impacts of health literacy. Pooled relative risk was 1.621 (95% confidence interval: 1.089-2.412) for mortality and 1.184 (95% confidence interval: 1.035-1.355) for readmission, indicating significant effects of health literacy. GRADE assessment showed "LOW" certainty for each outcome., Conclusion: Low health literacy was significantly associated with increased mortality and hospital readmission and decreased QOL in patients with CVD., Practice Implications: Considering low health literacy in clinical practice is very important to improve prognosis of CVD patients., (Copyright © 2021 Elsevier B.V.

Aims: To investigate the effect of mild cognitive impairment (MCI) on unplanned readmission in patients with coronary artery disease (CAD)., Methods and Results: From 2132 CAD patients, MCI was estimated with the Japanese version of the Montreal Cognitive Assessment (MoCA-J) in 243 non-dementia patients who met the study criteria. The primary outcome was unplanned hospital readmission after discharge. The incidence of MCI in this cohort was 33.3%, and 51 patients (21.0%) had unplanned readmission during a mean follow-up period of 418.6 ± 203.5 days. After adjusting for the covariates, MCI (hazard ratio, 2.28; 95% confidence interval: 1.09-4.76; P = 0.03) was independently associated with unplanned readmission in the multivariable Cox proportional hazard regression analysis. In the Kaplan-Meier analysis, the cumulative incidence of unplanned readmission for the MCI group was significantly higher than that for the non-MCI group (log-rank test, P < 0.001). Even after exclusion of the patients readmitted within 30 days of discharge, the main results did not change (log-rank test, P < 0.001)., Conclusion: Mild cognitive impairment was independently associated with unplanned readmission after adjustment for many independent variables in CAD patients. In addition to its short-term effects, the adverse effects of MCI had a persistent, long-term impact on CAD patients. Assessment of cognitive function should be conducted by health professionals prior to hospital discharge and during follow-up. To prevent readmission of CAD patients, it will be necessary to support solutions to the problems that inhibit secondary prevention behaviours based on the assessment of the patients' cognitive function., (Published on behalf of the European Society of Cardiology.

Background: Although more children with congenital heart disease (CHD) are reaching adulthood, they generally have some impairment compared to their healthy peers. Few studies have investigated the effect of exercise training on health-related quality of life (HRQOL) and/or physical activity in children with CHD., Purpose: The purpose of this study was to systematically review the effect of exercise training on HRQOL and/or physical activity and the types of training used in general., Methods: We searched relevant articles published from 2000 to 2021 in English and included intervention studies for children with CHD younger than 20 years who underwent exercise training. Afterwards, we excluded the studies not using HRQOL or physical activity as outcome measures, classified the extracted information according to outcome measures and types of interventions, and assessed the risk of bias of the included studies., Results: Finally, 10 articles were selected, and HRQOL in 3 articles and physical activity in 3 articles showed improvement after exercise training. However, 4 articles did not show improvement in these outcome measures, and 9 of the articles had a high risk of bias in blinding. Sport-based or play-based interventions were used in 5 articles, and prescribed or structured ones were used in 5 articles., Conclusion: Although exercise training for children with CHD may improve their HRQOL and/or physical activity, more studies are needed to assess the effect statistically. In children with CHD, sport-based or play-based interventions could be used as well as prescribed or structured interventions., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2022 The Authors.)

Aim: This study aimed to assess the association between physical frailty and clinical outcomes among older patients hospitalized for pneumonia., Methods: This study examined 852 consecutive patients hospitalized for pneumonia between October 2018 and September 2020. Patients who were <65 years old, scheduled for admission, did not receive inpatient rehabilitation, or died during admission were excluded. A short physical performance battery (SPPB) test was performed by physical therapists upon discharge. The primary outcome measure was a composite endpoint of readmission or mortality due to any cause within 6 months of discharge., Results: In total, 521 patients (median age, 80 years; interquartile range, 74-86 years) were included in the analyses, and were divided into the following two groups: robust group with SPPB scores >9 (n = 150), and physical frailty group with SPPB scores ≤9 (n = 371). Of these, 346 (66.4%) patients were men; and the median SPPB score was 6 (interquartile range, 1-10). During the median follow-up period of 53 days (interquartile range, 4-180 days), 92 (17.6%) patients were readmitted and 25 (4.8%) patients died. Patients with physical frailty were at an increased risk for the primary endpoint (hazard ratio, 2.21; 95% confidence interval, 1.44-3.41; P < 0.001); the risk remained significant after adjusting for multiple variables (adjusted hazard ratio, 1.70; 95% confidence interval, 1.05-2.74; P = 0.028)., Conclusions: Among older patients with pneumonia, physical frailty status at discharge was an independent risk factor for readmission and mortality within 6 months after initial discharge.

Background: We aimed to examine the relationship between the difficulty of activity using the arms and mild cognitive impairment (MCI), the relationship between the difficulty of activity using the arms and manual function, and cognitive function in patients with coronary artery disease (CAD)., Methods: We conducted a cross-sectional study of 263 non-dementia patients who met the study criteria from 2328 CAD patients. MCI was estimated with the Japanese version of the Montreal Cognitive Assessment (MoCA-J). The difficulty of activity using the arms was evaluated using the Disability of the Arm, Shoulder, Disability of the Arm, Shoulder and Hand and Hand (DASH) questionnaire. Manual function was evaluated by pinch strength and handgrip strength., Results: Age (odds ratio, 1.10), three-fingered pinch strength (odds ratio, 0.69), and DASH score (odds ratio, 1.03) were independently associated with MCI in the multivariable logistic regression analysis. Hemoglobin (β=-0.15), handgrip strength (β=-0.37), and MoCA-J score (β=-0.15) were independently associated with DASH score (Model 1: p<0.001, adjusted R 2 =0.33); hemoglobin (β=-0.17), eGFR (β=-0.14), three-fingered pinch strength (β=-0.25), and MoCA-J score (β=-0.14) were independently associated with DASH score in the multivariate regression analysis (Model 2: p<0.001, adjusted R 2 =0.31)., Conclusions: The difficulty of activity using the arms was independently associated with manual and cognitive function and MCI in CAD patients., (Copyright © 2020.

Slow gait speed and restricted life-space mobility predict cognitive decline and dementia in healthy older adults, yet the relation between gait speed or life-space mobility and cognitive function remains poorly understood in patients with coronary artery disease (CAD). We, therefore, examined the following relations: that between gait speed and cognitive function, and mild cognitive impairment (MCI) and that between life-space mobility and cognitive function, and MCI. We conducted a cross-sectional study of 240 non-dementia patients who met the study criteria from 2132 consecutive CAD patients. MCI was estimated with the Japanese version of the Montreal Cognitive Assessment (MoCA-J). Gait speed was measured to perform gait trials at the patients' usual walking pace, and life-space mobility was evaluated using the Life-Space Assessment (LSA). We investigated the relation between gait speed or life-space mobility and cognitive function by Pearson correlation analysis, whereas multivariable logistic regression analysis was conducted for detecting MCI. Gait speed and LSA scores were positively associated with the MoCA-J score (r = 0.54, p < 0.001 and r = 0.44, p < 0.001, respectively), and both were independently associated with MCI in the multivariable logistic regression analysis (odds ratio 0.007, p < 0.001, and odds ratio 0.98, p = 0.038, respectively). Cognitive impairment can be easily detected by assessment of gait speed and life-space mobility. Interventions to improve gait speed and life-space mobility may lead to the improvement of cognitive function and MCI in patients with CAD.

The objective effects of early mobilization on physical function in patients after cardiac surgery remain unknown. The purpose of the present study was to clarify the effects of early mobilization on physical function in patients after cardiac surgery through meta-analysis. Four electronic databases were searched on 2 August 2019. We used search keywords related to "early mobilization", "cardiac surgery", and "randomized controlled trials". All randomized controlled trials conducting early mobilization after cardiac surgery were included. We defined early mobilization as the application of physical activity within the first five postoperative days. Citations and data extraction were independently screened in duplicate by two authors. The meta-analysis was conducted using random-effects modeling with EZR software. The primary outcome was the distance walked during the six-minute walking test at hospital discharge. Six randomized controlled trials comprising 391 patients were included following screening of 591 studies. All studies included coronary artery bypass grafting as the cardiac surgery conducted. Early mobilization started on postoperative days 1-2 and was conducting twice daily. Early mobilization showed a trend of being combined with respiratory exercise or psychoeducation. The meta-analysis showed that the distance walked during the 6-min walking test improved by 54 m (95% confidence interval, 31.1-76.9; I 2 = 52%) at hospital discharge. The present study suggested that early mobilization after cardiac surgery may improve physical function at discharge.

Background: The relation between levels of n-6 polyunsaturated fatty acids (PUFAs) and cognitive function and mild cognitive impairment (MCI) in patients with coronary artery disease (CAD) is unclear. The purpose of the present study was to examine the associations between levels of n-6 PUFAs and cognitive function and MCI in patients with CAD., Methods: We conducted a cross-sectional study of 129 patients with CAD but without probable dementia. MCI was estimated with the Japanese version of the Montreal Cognitive Assessment (MoCA-J). We classified patients into the normal cognitive group and MCI group and compared their clinical characteristics and serum levels of PUFAs. The relation between these levels and cognitive function and MCI was clarified with Pearson correlation analysis and logistic regression analysis., Results: The serum levels of dihomo-γ-linolenic acid (DGLA) in the CAD patients with MCI were significantly lower than those in the patients with normal cognitive function (p= 0.04). The serum levels of DGLA were positively associated with the MoCA-J score (r= 0.24, p= 0.005) and significantly associated with MCI in the univariate logistic regression analysis (odds ratio, 0.97; p= 0.035). However, in the multivariate logistic regression analysis, only age was significantly associated with MCI (odds ratio, 1.11; p < 0.001)., Conclusions: The serum levels of DGLA were associated with cognitive function and MCI in patients with CAD. Although not an independent predictor, DGLA might be one useful marker with which to identify early cognitive decline in these patients., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2019 Elsevier Ltd.

Background: The relationship between mild cognitive impairment (MCI) and pinch strength in patients with cardiovascular disease is unclear. The purpose of the present study was to examine the associations among MCI and pinch strength and to determine a pinch strength cut-off value for use in the assessment of MCI., Methods: We conducted a cross-sectional study of 135 patients with cardiovascular disease but without probable dementia. MCI was estimated with the Japanese version of the Montreal Cognitive Assessment. We classified patients into the normal cognitive group and MCI group and compared their clinical characteristics, handgrip strength, and pinch strength. The relation between MCI and pinch strength was clarified with logistic regression analysis, and the cut-off value for three-fingered pinch strength was determined by receiver operating characteristic curve analysis., Results: The incidence of MCI was 37.0 %. Significant differences between the two groups were identified for age, body mass index, hemoglobin, estimated glomerular filtration rate, albumin, dyslipidemia, use of nitrates, educational background, handgrip strength, and pinch strength. After multivariate analysis, three-fingered pinch strength was significantly associated with MCI (odds ratio 0.77, p= 0.02). The cut-off value of three-fingered pinch strength for predicting MCI was 6.75 kgf (area under the curve = 0.71; p< 0.001)., Conclusions: Pinch strength was one independent factor significantly associated with MCI in patients with cardiovascular disease. The determination of a cut-off value for three-fingered pinch strength that can predict MCI may be one important factor in the early screening for MCI in the daily clinical setting., (Copyright © 2020 Japanese College of Cardiology.

Background: Infertility is a global social issue, and reproductive health is a priority in global health. This review aimed to study the relation between physical activity (PA) and infertility in non-obese or non-overweight women., Methods: We used search strategies in the National Library of Medicine database including the PubMed database to October 2019 to find articles related to women and fertility, infertility, exercise, PA, pregnancy rate, live births, fecundability, and conception. Only cohort studies or randomized controlled trials in English were chosen for review that included outcomes directly related to becoming pregnant. We selected studies in which the participants were categorized by low or high body mass index (BMI)., Results: We found 6 papers meeting our criteria. In the association between PA and outcome, vigorous PA in women with low BMI resulted in both positive and negative effects that were weaker than those in women with high BMI. Among women with low BMI, moderate PA was weakly but positively associated with outcome whereas walking was not., Conclusion: We observed some trends and a slight difference between the outcomes of women with low versus high BMI. There are only a few studies on infertile women with low BMI, and further investigation is warranted., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

Objectives: Nutritional status affects cerebral circulation and cognitive function. More attention needs to be paid to nutritional status in coronary artery disease (CAD) patients, yet the relation between nutritional status or dietary intake (DI) and cognitive function or mild cognitive impairment (MCI) in CAD patients remain unclear. Thus, we examined the following relations: 1) that between nutritional status and cognitive function, and MCI and 2) that between DI and cognitive function, and MCI., Design, Setting, and Participants: We conducted a cross-sectional study of 208 patients with CAD but without dementia., Measurements: MCI was estimated with the Japanese version of the Montreal Cognitive Assessment (MoCA-J). Nutritional status was assessed by the Geriatric Nutritional Risk Index (GNRI), and DI was assessed by total energy intake per day. We investigated the relation between nutritional status or DI and cognitive function by Pearson correlation analysis, and that between nutritional status or DI and MCI by multivariable logistic regression analysis., Results: The GNRI and DI were positively associated with the MoCA-J score (r = 0.23, p < 0.001, and r = 0.24, p < 0.001, respectively), and both were independently associated with MCI in the multivariable logistic regression analysis (odds ratio, 0.96; p = 0.045, and odds ratio, 0.998; p = 0.020, respectively)., Conclusions: Poor nutritional status and low DI were found to be significantly associated with cognitive function and MCI in CAD patients. Our findings regarding nutritional status and DI might be useful for clinicians to prevent or intervene in the early cognitive decline of inpatients with CAD., Competing Interests: The authors declare that they have no conflict of interest.

Social communication and motor skill deficits are prevalent characteristics of individuals with autism spectrum disorder (ASD). This systematic research review investigates whether and how broad social skills and motor skills may be related among individuals with ASD. We performed a PubMed search of articles written in English, using these study inclusion criteria: (a) an association between social and motor and skills among individuals previously diagnosed with autism; (b) one or more social skills measures were used; and (c) one or more measures of gross or fine motor skills were used. We classified data into two categories, and we based the association of these variables on correlation coefficients, p -values, coefficients of determination, and authors' description of "may be associated" and "may not be associated." Despite heterogeneity among these relevant studies, a highly likely association between social and motor skills emerged. Of a total of 16 studies reviewed, 12 reported associations between these skill sets. Three studies reported that fine motor skills had a stronger relationship with social skills than did gross motor skills. Among the gross motor skills associated with social skills, object control skills seemed most closely linked to social skills. Among fine motor skills, manual dexterity seemed to most closely related to social skills.

Activities of daily living (ADL) are maintained in patients with mild cognitive impairment (MCI), but, in patients with cardiovascular disease, ADL may have already declined. MCI combined with cardiac disease may accentuate the decline of ADL in these patients. Because the relationship between MCI and ADL in patients with cardiovascular disease is unclear, we examined the associations between MCI and ADL in these patients. We conducted a cross-sectional study of 114 patients with cardiovascular disease but without probable dementia. MCI was estimated with the Japanese version of the Montreal Cognitive Assessment (MoCA-J). We classified patients into the normal cognitive group and MCI group, and compared their clinical characteristics, physical function [Short Physical Performance Battery (SPPB), gait speed, handgrip strength, and knee extensor muscle strength], and ADL [via the Functional Independence Measure (FIM)]. We used logistic regression analysis to evaluate the specific association between MCI and ADL. The incidence of MCI was 36.0%. Significant differences between the two groups were identified for age, body mass index, estimated glomerular filtration rate, albumin, dyslipidemia, educational background, SPPB, gait speed, handgrip strength, and FIM. However, after adjustment for covariates, only FIM was significantly associated with MCI (odds ratio 0.74, 95% confidence interval 0.65-0.84, p < 0.001). ADL was the only independent factor significantly associated with MCI in patients with cardiovascular disease. ADL may be hindered in these patients, even at an early stage of MCI. Therefore, early intervention is necessary to prevent ADL decline from the time of MCI onset or before.

Background and Aims: It is important to encourage physical activity in patients with cardiovascular disease (CVD), and self-monitoring is considered to contribute to increased physical activity. However, the effects of self-monitoring on CVD patients remain to be established. In this study, we examined the influence of self-monitoring on physical activity of patients with CVD via a systematic review and meta-analysis., Methods: Screening of randomized controlled trials only was undertaken twice on PubMed (date of appraisal: August 29, 2017). The inclusion criteria included outpatients with CVD, interventions for them, daily step counts as physical activity included in the outcome, and self-monitoring included in the intervention. Assessments of the risk of bias and meta-analysis in relation to the mean change of daily step counts were conducted to verify the effects of self-monitoring., Results: From 205 studies retrieved on PubMed, six studies were included, with the oldest study published in 2005. Participants included 693 patients of whom 541 patients completed each study program. Their mean age was 60.8 years, and the ratio of men was 79.6%. From these 6 studies, a meta-analysis was conducted with 269 patients of 4 studies including only RCTs with step counts in the intervention group and the control group, and self-monitoring significantly increased physical activity (95% confidence interval, 1916-3090 steps per day, p < 0.05). The average intervention period was about 5 months. Moreover, four studies involved intervention via the internet, and five studies confirmed the use of self-monitoring combined with other behavior change techniques., Conclusion: The results suggest that self-monitoring of physical activity by patients with CVD has a significantly positive effect on their improvement. Moreover, the trend toward self-monitoring combined with setting counseling and activity goals, and increased intervention via the internet, may lead to the future development and spread of self-monitoring for CVD patients.
