Association Between Second-hand Smoke Exposure and Depressive Symptoms Among Japanese Adults: A Cross-sectional Study.

BACKGROUND: Second-hand smoke exposure has been associated with poor mental health. However, among Japanese adults, little is known about the association between second-hand smoking and depressive symptoms. We examined this association in a cross-sectional study among a Japanese general adult population sample. METHODS: Japanese adults were recruited from the Japan Multi-Institutional Collaborative Cohort Study in the Okazaki area between 2012 and 2017. Second-hand smoke exposure and smoking status were assessed using a self-administered questionnaire. Based on their frequency of exposure to second-hand smoke, non-smokers and smokers were categorized as "almost never," "sometimes," and "almost every day". Depressive symptoms were defined by a Kessler 6 score ≥5 points. We performed a multivariable Poisson regression analysis to obtain adjusted prevalence ratios (PRs) and 95% confidence intervals (CIs) for depressive symptoms. RESULTS: Overall, 5,121 participants (4,547 non-smokers and 574 smokers) were included whose mean age was 63.6 (standard deviation [SD], 10.3) years for non-smokers and 59.33 (SD, 10.2) years for smokers. The association between second-hand smoking and depressive symptoms was significant among non-smokers, but not among smokers. Among non-smokers, PRs compared with "almost never" were 1.25 (95% CI, 1.09-1.42) for "sometimes" and 1.41 (95% CI, 1.09-1.84) for "almost every day" (P for trend <0.001); among smokers, PRs compared with "almost never" were 1.30 (95% CI, 0.82-2.06) for "sometimes" and 1.44 (95% CI, 0.90-2.33) for "almost every day" (P for trend = 0.144). CONCLUSIONS: Second-hand smoking and depressive symptoms were associated among non-smokers. Our findings indicate the importance of tobacco smoke control for mental health.

Physical Activity Earlier in Life Is Inversely Associated With Insulin Resistance Among Adults in Japan.

BACKGROUND: It is known that physical activity affects glucose metabolism. However, there have been no reports on the influence of physical activity earlier in life on subsequent glucose metabolism. Therefore, we analyzed the influence of physical activity in earlier decades of life on insulin resistance in middle aged and older residents in Japan. METHODS: The subjects were 6,883 residents of Okazaki City between the ages of 40 and 79 years who underwent physical examinations at the Okazaki City Medical Association Public Health Center from April 2007 through August 2011. They gave informed consent for participation in the study. Data on individual characteristics were collected via a questionnaire and from the health examination records. Fasting blood glucose and insulin levels were used to calculate the homeostatic model assessment of insulin resistance (HOMA-IR). HOMA-IR >1.6 was considered to indicate insulin resistance for the purpose of logistic regression models. RESULTS: The study sample included 3,683 men and 3,200 women for whom complete information was available. For those who exercised regularly throughout their teens to their 30s-40s, the odds ratio for having insulin resistance was 0.75 (95% confidence interval [CI], 0.58-0.96) for men and 0.76 (95% CI, 0.58-0.99) for women after adjusting for other variables, including age, body mass index, and present physical activity. A linear trend was also observed in both men and women. CONCLUSIONS: Subjects who have exercised regularly in the early decades of life are less likely to have insulin resistance later in life.

Handling missing data in an FFQ: multiple imputation and nutrient intake estimates.

OBJECTIVE: We aimed to examine missing data in FFQ and to assess the effects on estimating dietary intake by comparing between multiple imputation and zero imputation. DESIGN: We used data from the Okazaki Japan Multi-Institutional Collaborative Cohort (J-MICC) study. A self-administered questionnaire including an FFQ was implemented at baseline (FFQ1) and 5-year follow-up (FFQ2). Missing values in FFQ2 were replaced by corresponding FFQ1 values, multiple imputation and zero imputation. SETTING: A methodological sub-study of the Okazaki J-MICC study.ParticipantsOf a total of 7585 men and women aged 35-79 years at baseline, we analysed data for 5120 participants who answered all items in FFQ1 and at least 50% of items in FFQ2. RESULTS: Among 5120 participants, the proportion of missing data was 3·7%. The increasing number of missing food items in FFQ2 varied with personal characteristics. Missing food items not eaten often in FFQ2 were likely to represent zero intake in FFQ1. Most food items showed that the observed proportion of zero intake was likely to be similar to the probability that the missing value is zero intake. Compared with FFQ1 values, multiple imputation had smaller differences of total energy and nutrient estimates, except for alcohol, than zero imputation. CONCLUSIONS: Our results indicate that missing values due to zero intake, namely missing not at random, in FFQ can be predicted reasonably well from observed data. Multiple imputation performed better than zero imputation for most nutrients and may be applied to FFQ data when missing is low.

[CORRESPONDENCE OF POLYMICROBIAL BACTERIURIA IN THE UNCOMPLICATED URINARY TRACT INFECTION OF THE PREMENOPAUSAL WOMAN].

(Objectives) We report the clinical features about polymicrobial bacteria detection cases in the uncomplicated urinary tract infection of the premenopausal woman from the voided midstream urine culture. (Methods) We retrospectively reviewed the premenopausal woman from 18-49 years patients visited Sendai City Hospital from April, 2006 to December, 2014, diagnosed uncomplicated cystitis or uncomplicated pyelonephritis. We analyzed for 375 specimens from the voided midstream urine culture. (Results) Among 375 specimens, the urine culture-positive for uropathogens were 211 specimens. The monomicrobial bacterial were detected in 184 specimens (87.2%) and polymicrobial bacterial specimens were 27 specimens (12.8%). The most combination group was the caused bacteria and periurethral microorganisms in 20 specimens (74.1%). Then 6 periurethral microorganisms specimens (22.2%), the caused bacteria were only 1 specimen was overlapped (3.7%). The case of urinary tract infections recurrence or revealed voiding dysfunction that need periodic treatment were more prevalent in the polymicrobial than the monomicrobial group (22.2% vs 9.8%, p=0.043). (Conclusions) When polymicrobial bacteria were detected in uncomplicated urinary tract infection in premenopausal woman, it was confirmed that there were the most combinations of caused bacteria and periurethral microorganisms. In these cases, treatment intended for only the caused bacteria. A risk of the infection recurrence and voiding dysfunction were statistically significant higher rate in the polymicrobial bacteria detection cases, and it might be necessary to consider that search to complicated urinary tract infection.

Association between laughter, frailty, and depression in rheumatoid arthritis patients.

OBJECTIVE: This study aimed to determine whether there are associations between laughter, disease activity, frailty, and depression in rheumatoid arthritis (RA) patients. METHODS: A total of 240 patients were included in this prospective cohort study on frailty in RA patients between March 2021 and June 2022. Patients were divided into the following four groups according to the frequency of laughter: "almost every day," "1-5 days per week," "1-3 days per month," and "never or almost never." Patient characteristics were compared among the four groups by analysis of variance. Factors associated with laughter were identified by multivariable logistic analysis. RESULTS: The mean 28-joint Disease Activity Score using CRP was 1.91, with 70.7% of patients in remission and 12.6% in low disease activity. For the "almost every day" (42.5% of patients), "1-5 days per week" (40.0%), "1-3 days per month" (11.3%), and "never or almost never" (6.3%) groups, scores of the Kihon Checklist (KCL) for assessing frailty status were 3.5, 4.6, 7.3, and 8.1 (p < .001), respectively, and scores of the Beck Depression Inventory (BDI-II) were 8.4, 10.7, 15.1, and 16.5 (p < .001), respectively. Multivariable analysis revealed that KCL (OR: 0.81, 95% CI: 0.73-0.90) and BDI-II (OR: 0.91, 95% CI: 0.86-0.95) scores were independently associated with the frequency of laughter. CONCLUSION: Frailty and depression were associated with laughter in RA patients with controlled disease activity. Interventions aimed at not only disease activity control but also frailty prevention may lead to a life filled with laughter.

Early Introduction of Power Mobility Devices for Children with Fukuyama Congenital Muscular Dystrophy and Its Psychological Impact on Caregivers: A Case Report.

Recently, motorized mobility devices (or power mobility devices (PMDs)) have been introduced for infants and toddlers who lack the means for self-mobility. Previous reports have primarily focused on PMDs for individuals with cerebral palsy. Few have explored PMDs for individuals with neuromuscular diseases who have intellectual disabilities. This report presents a case study of the early introduction of a PMD for an infant with Fukuyama congenital muscular dystrophy and presents the results of an interview with the father regarding psychological aspects and the child's manipulative abilities. The PMD was introduced at the age of 1 year and 10 months, and the changes during the 19 months after the introduction were evaluated six times, using the Assessment of Learning Powered mobility use tool (ALP). A semi-structured interview with the father was conducted 19 months after the introduction. The ALP evaluation and the interview were conducted by one physical therapist and two physical therapy students, and the results were shared with the hospital's physical therapist and nurses at the nursing facility. This report provides a basis for expanding the scope of PMD use and for considering the family's involvement, especially for the child.

Home-Based Frailty Prevention Program for Older Women Participants of Kayoi-No-Ba during the COVID-19 Pandemic: A Feasibility Study.

This study presents a single-arm intervention that aimed to determine the feasibility of a three-month home-based exercise program to prevent the progression of frailty during COVID-19. We recruited four groups of Kayoi-no-ba, or community salons for frailty prevention, and a total of 69 community-dwelling older women who belonged to one of the Kayoi-no-ba in a preliminary study for a follow-up study. The intervention program was developed on the basis of the 5A approach, and the focus group by the volunteer leaders of Kayoi-no-ba. We adapted the National Center for Geriatrics and Gerontology Home Exercise Program for Older People for 10-min daily home-based exercise. For feasibility outcomes, 91.3% of the participants completed the intervention program, whereas the percentage of exercise performed was 86.5% during the intervention period. For health-related outcomes, the five times sit-to-stand test exhibited significant improvement after the intervention. The results of feasibility outcomes indicate that the program may be feasible due to the high rates of completion and exercise performed. Additionally, improvement was noted for the health indicators of the five times sit-to-stand test, which may help prevent frailty. The feasibility trial has provided the necessary data to design a future-cluster randomized controlled trial.

Surveying Therapists on Seating Approaches for Patients with Muscular Dystrophy in Japan.

Patients with muscular dystrophy (MD) need fitted wheelchairs. This study aimed to ascertain physiotherapists and occupational therapists' opinions about the current wheelchair seating process for patients with MD in Japan. We identified 266 academic papers published between August 2014 and July 2019 with the keywords "muscular dystrophy" and either "physiotherapy" or "occupational therapy." We then sent survey requests to 140 physiotherapists and occupational therapists (who were among the authors of the aforementioned papers), of whom 41 agreed to partake in this study. We found that the time required for each seating was 30-60 min for three types of MD, and the most commonly reported time to trial fitting was 1-3 months. In addition, health insurance reimbursements for seating were considered part of disease-specific rehabilitation in most cases, and most therapists were more or less satisfied with the current seating procedure. Physiotherapists had the highest degree of reflection of their views (wishes) regarding seating, followed by MDs and their families. In Japan, seating has been regarded as a medical practice since 2017. In the future, we would like to investigate the seating concept for individual therapists in detail.

The Association between Family Caregiver Burden and Subjective Well-Being and the Moderating Effect of Social Participation among Japanese Adults: A Cross-Sectional Study.

We examined the association between family caregiver burden and subjective well-being with social participation's moderating effect among Japanese adults. Data were obtained from a cross-sectional survey by the Japan Multi-Institutional Collaborative Cohort Study in the Okazaki area between 2013 and 2017. Study participants included 5321 adults who visited the Public Health Center for annual health check-ups and answered a questionnaire regarding health status and lifestyle. Subjective well-being was assessed by a single item, out of 10 points, and analyzed with multivariable linear regression analysis models by subjective family caregiver burden ("none", "mild", "severe"), stratified by gender. Ultimately, 2857 men and 2223 women were included. Mean participant age (standard deviation) in years was 64.7 (10.4) for men and 61.3 (10.0) for women. Multivariable analysis revealed that, among women, higher caregiver burden was inversely associated with subjective well-being (p for trend < 0.001), and the interaction of severe caregiver burden and social participation on subjective well-being was positive and significant (p for interaction < 0.05). High family caregiver burden was inversely associated with subjective well-being among Japanese women, but moderated by the caregiver's social participation, suggesting the importance of community development that enables family caregivers' social participation to protect their subjective well-being.
