RESUMO

INTRODUCTION: Breakfast-skipping habits are associated with adverse health outcomes including coronary heart disease, metabolic syndrome, and diabetes mellitus. However, it remains uncertain whether skipping breakfast affects chronic kidney disease (CKD) risk. This study aimed to examine the association between skipping breakfast and progression of CKD. METHODS: We retrospectively conducted a population-based cohort study using the data from the Iki City Epidemiological Study of Atherosclerosis and Chronic Kidney Disease (ISSA-CKD). Between 2008 and 2019, we included 922 participants aged 30 years or older who had CKD (estimated glomerular filtration rate <60 mL/min/1.73 m2 and/or proteinuria) at baseline. Breakfast skippers were defined as participants who skipped breakfast more than 3 times per week. The outcome was CKD progression defined as a decline of at least 30% in the estimated glomerular filtration rate (eGFR) from the baseline status. Cox proportional hazards models were used to calculate hazard ratios (HRs) and 95% confidence intervals (CIs) for CKD progression, adjusted for other CKD risk factors. RESULTS: During a follow-up period with a mean of 5.5 years, CKD progression occurred in 60 (6.5%) participants. The incidence rate (per 1,000 person-years) of CKD progression was 21.5 in the breakfast-skipping group and 10.7 in the breakfast-eating group (p = 0.029), respectively. The multivariable-adjusted HR (95% CI) for CKD progression was 2.60 (95% CI: 1.29-5.26) for the breakfast-skipping group (p = 0.028) compared with the group eating breakfast. There were no clear differences in the association of skipping breakfast with CKD progression in subgroup analyses by sex, age, obesity, hypertension, diabetes mellitus, baseline eGFR, and baseline proteinuria. CONCLUSION: Skipping breakfast was significantly associated with higher risk of CKD progression in the general Japanese population.

RESUMO

PURPOSE: The aim of this meta-analysis was to investigate the effect of pharmacotherapy for overactive bladder on the pathogenesis of urinary tract infection. MATERIALS AND METHODS: A comprehensive search was performed in MEDLINE and the Cochrane Library using terms for overactive bladder, antimuscarinic agents, and beta 3-adrenoceptor agonists. The primary end point was the emergence of urinary tract infection after pharmacotherapy for overactive bladder. The secondary end point was the emergence of urinary retention, dysuria, and/or increased residual urine volume after overactive bladder treatment. Meta-analyses were conducted using random-effects models. RESULTS: A total of 35,939 patients in 33 trials (29 trials of antimuscarinic agents vs placebo, and 9 trials of beta 3-adrenoceptor agonists vs placebo) that included patients with overactive bladder were identified. At 1-3 months after treatment, the incidence of urinary tract infections was statistically significantly higher in the patients treated with antimuscarinic agents (RR: 1.23, 95% CI: 1.04, 1.45; P = .013) than in the placebo control group. The incidence of urinary tract infections was not increased in the patients treated with beta 3-adrenoceptor agonists (RR: 1.04, 95% CI: 0.76, 1.42; P = .796). Antimuscarinic agents also statistically significantly increased the risks of urinary retention, dysuria, and/or increased residual urine volume (RR: 2.88, 95% CI: 1.79, 4.63; P < .001), whereas beta 3-adrenoceptor agonists did not (RR: 1.26, 95% CI: 0.38, 4.14; P = .708). CONCLUSIONS: This meta-analysis showed that antimuscarinic agents statistically significantly increased the incidences of urinary tract infection and lower urinary tract symptoms and dysfunction, but beta 3-adrenoceptor agonists did not. To prevent urinary tract infection emergence, beta 3-adrenoceptor agonists might be safer than antimuscarinic agents.

RESUMO

AIMS: This study aimed to conduct a systematic review of studies on the outcomes of long-term hospitalisation of individuals with severe mental illness, considering readmission rates as the primary outcome. METHODS: Studies considered were those in which participants were aged between 18 and 64 years with severe mental illness; exposure to psychiatric hospitals or wards was long-term (more than one year); primary outcomes were readmission rates; secondary outcomes were duration of readmission, employment, schooling, and social participation; and the study design was either observational or interventional with a randomised controlled trial (RCT) design. Relevant studies were searched using MEDLINE, PsycINFO, Web of Science, CINAHL, and the Japan Medical Abstract Society. The final search was conducted on 1 February 2022. The risk of bias in non-randomised studies of interventions was used to assess the methodological quality. A descriptive literature review is also conducted. RESULTS: Of the 11,999 studies initially searched, three cohort studies (2,293 participants) met the eligibility criteria. The risk of bias in these studies was rated as critical or serious. The 1-10 years readmission rate for patients with schizophrenia who had been hospitalised for more than one year ranged from 33 to 55%. The average of readmission durations described in the two studies was 70.5 ± 95.6 days per year (in the case of a 7.5-year follow-up) and 306 ± 399 days (in the case of a 3-8-year follow-up). None of the studies reported other outcomes defined in this study. CONCLUSIONS: The readmission rates in the included studies varied. Differences in the follow-up period or the intensity of community services may have contributed to this variability. In countries preparing to implement de-institutionalisation, highly individualised community support should be designed to avoid relocation to residential services under supervision. The length of stay for readmissions was shorter than that for index admissions. The results also imply that discharge to the community contributes to improved clinical outcomes such as improved social functioning. The validity of retaining patients admitted because of the risk of rehospitalisation was considered low. Future research directions have also been discussed.

RESUMO

INTRODUCTION: We have developed an online cognitive test (Brain Assessment [BA]) which exhibits moderate correlations with established neuropsychological tests. We made a short version of the BA that requires only 10 min and investigated correlations with the original version. PARTICIPANTS AND METHODS: Three hundred and twenty-three subjects (26-82 years old, mean age 41.9 years) were recruited via the internet and performed the original version of the BA online, and, for the analyses of the original and short version, the results of the whole and of the first 2 min were utilized, respectively. Correlations were evaluated between both versions, and 144 subjects agreed to be interviewed about BA utilization. RESULTS: Correlations between the short and original versions of the BA were strong (memory of numbers, r = 0.72: total, r = 0.73) or moderate (memory of words, r = 0.66; visuospatial, r = 0.42; working memory, r = 0.53; judgment, r = 0.54). We found a strong negative correlation between the "memory of words" subtest and age (short version, r = -0.85; original version, r = -0.88). Regarding the interview, most wanted to be assessed by the short version every year. In the case of a concerning score, they would then want to be examined by the original version of the BA and/or more specific neuropsychological tests. DISCUSSION: We found that the short and the original versions of the BA exhibited strong correlations, and the correlation coefficients between age and subtest scores were almost the same between the two versions. CONCLUSION: The short version of the BA will be useful to perform cognitive assessments in the clinic.

RESUMO

BACKGROUND: Patient and public involvement (PPI) has become essential in health research. However, little is known about multiple stakeholders' perspectives on the implementation of PPI in community mental health research settings. The present study aimed to qualitatively analyse multiple stakeholders' views on PPI, including potential concerns, barriers and approaches. METHODS: This study involved conducting focus group interviews and collecting qualitative data from 37 participants in multiple stakeholder groups (patients = 6, caregivers = 5, service providers = 7, government staff = 5 and researchers = 14) in the community mental health field. The data were qualitatively analysed using a data-driven approach that derived domains, themes and subthemes related to perspectives on PPI and to specific challenges and approaches for implementing PPI. RESULTS: The qualitative analysis identified four domains. The 'Positive views and expectations regarding PPI' domain consisted of themes related to supportive views of PPI in a mental health service research setting and improvements in the quality of research and service. The 'General concerns about PPI' domain included themes concerning the need for non-PPI research and tokenism, excessive expectations concerning social changes and use of evidence from PPI research, and heavy burdens resulting from PPI. The 'Specific issues regarding the implementation of PPI' domain consisted of four themes, including academic systems, selection methods (e.g., representativeness and conflict of interest issues), relationship building, and ambiguous PPI criteria. In particular, all stakeholder groups expressed concerns about relational equality during PPI implementation in Japan. The 'Approaches to PPI implementation' domain included themes such as facilitating mutual understanding, creating a tolerant atmosphere, establishing PPI support systems (e.g., training, ethics and human resource matching) and empowering patient organizations. CONCLUSION: The study replicated most of the barriers and approaches to PPI reported by qualitative research in Western counties. However, utilization of evidence produced by PPI research and partnership in the PPI process may be particularly serious issues in Japan. Future PPI studies should carefully address solutions that fit each culture. PATIENT OR PUBLIC CONTRIBUTION: A patient-researcher was involved in all stages of this project, from development of the research topic and the protocol to manuscript preparation.

RESUMO

OBJECTIVE: White matter hyperintensity (WMH), defined as abnormal signals on magnetic resonance imaging (MRI), is an important clinical indicator of aging and dementia. Although MRI image analysis software can automatically detect WMH, the quantitative accuracy of periventricular hyperintensity (PVH) and deep white matter hyperintensity (DWMH) is unknown. MATERIALS AND METHODS: This study was a sub-analysis of MRI data from an ongoing hospital-based prospective cohort study (the Gimlet study). Between March 2016 and March 2017, we enrolled patients who visited our memory clinic and agreed to undergo medical assessments of cognitive function and fecal examination to study the gut microbiome. Participants with a history of stroke were excluded. WMH was independently quantitatively analyzed using two MRI imaging analysis software modalities: SNIPER and FUSION. Intraclass correlation coefficients and the mean difference in volume were calculated and compared between modalities. RESULTS: The data of 87 patients (49 women, mean age 74.8 ± 7.9 years) were analyzed. Both total WMH and DWMH volumes obtained using FUSION were greater (p < 0.001), and PVH volume was smaller (p < 0.001) than those obtained using SNIPER. Intraclass correlation coefficients for the lesion measurements of WMH, PVH, and DWMH between the different software were 0.726 (p < 0.001), 0.673 (p < 0.001), and 0.048 (p = 0.231), respectively. CONCLUSIONS: There were significant differences in the quantitative data of WMH between the two MRI imaging analysis software modalities. Thus, care should be taken for quantitative assessments of WMH.

RESUMO

INTRODUCTION: There are several problems with standard in-person neuropsychological assessments, such as habituation, necessity of human resources, and difficulty of in-person assessment under societal conditions during the outbreak of coronavirus disease 2019. Thus, we developed an online cognitive test (the Brain Assessment [BA]). In this study, we investigated the correlation between the results of the BA and those of established neuropsychological tests. PARTICIPANTS AND METHODS: Seventy-seven elderly persons (mean 71.3 ± 5.1 years old; range 65-86; male:female = 45:32) were recruited through the internet. Correlations were evaluated between the BA and the following widely used neuropsychological tests: the mini-mental state examination (MMSE), the Raven's colored progressive matrices (RCPM), the logical memory I and II of the Rivermead Behavioral Memory Test, the word fluency (WF) test, and the Trail-Making TestA/B. RESULTS: We found moderate correlations between the total cognitive score of the BA and the total score of the MMSE (r = 0.433, p < 0.001), as well as between the total BA score and the total RCPM score (r = 0.582, p < 0.001) and time to complete the RCPM (r = 0.455, p < 0.001). Moderate correlations were also observed between the cognitive score of the memory of words BA subtest and the LM-I (r = 0.518, p < 0.001), the mental rotation subtest and figure drawing (r = 0.404, p < 0.001), the logical reasoning subtest and total RCPM score (r = 0.491, p < 0.001), and the memory of numbers and words subtests and WF (memory of numbers and total WF: r = 0.456, p < 0.001; memory of words and total WF: r = 0.571, p < 0.001). DISCUSSION: We found that the BA showed moderate correlations between established neuropsychological tests for intellect, memory, visuospatial function, and frontal function. The MMSE and the RCPM reflect Spearman's s-factor and g-factor, respectively, and thus the BA also covered both factors. CONCLUSION: The BA is a useful tool for assessing the cognitive function of generally healthy elderly persons.

RESUMO

Glucose intolerance is often observed in patients with pheochromocytoma. However, it remains controversial issue that glucose intolerance on pheochromocytoma is caused by impaired insulin secretion and/or by increased insulin resistance. We aimed to reveal the mechanism of glucose intolerance on pheochromocytoma with regard to the type and amount of catecholamines released. We evaluated 12 individuals diagnosed with pheochromocytoma and who underwent surgery to remove it. We examined glycemic parameters before and after surgery and investigated the association between the change of parameters of insulin secretion (homeostasis model assessment of ß-cell function (HOMA-ß)), insulin resistance (homeostasis model assessment of insulin resistance (HOMA-IR)) and that of urinary levels of metanephrine/normetanephrine before and after surgery. Overall, fasting plasma glucose, glycated hemoglobin (HbA1c), HOMA-ß, and HOMA-IR were improved significantly after surgery. Regression analysis showed that the improvement in HOMA-ß from before to after surgery was significantly positively associated with an improvement in urinary levels of metanephrine from before to after surgery and showed a significantly negative association with improvement in urinary levels of normetanephrine from before to after surgery. The improvement in HOMA-IR from before to after surgery was significantly positively associated with an improvement in urinary levels of normetanephrine from before to after surgery. Our results showed that pheochromocytoma extirpation improved glycemic parameters. Furthermore, the different effects elicited by excess amounts of adrenaline and noradrenaline on glucose intolerance were demonstrated.

RESUMO

A 63-year-old, right-handed professional chorus conductor developed right putaminal hemorrhage, and became unable to experience emotion while listening to music. Two years later, neurological examination revealed slight left hemiparesis. Neuromusicological assessments revealed impaired judgment of "musical sense," and the inability to discriminate the sound of chords in pure intervals from those in equal temperament. Brain MRI and tractography identified the old hemorrhagic lesion in the right putamen and impaired fiber connectivity between the right insula and superior temporal lobe. These findings suggest that musical anhedonia might be caused by a disconnection between the insula and auditory cortex.

RESUMO

The efficacy of renal denervation (RDN) has been controversial, but recent randomized sham-controlled trials demonstrated significant blood pressure reductions after RDN in patients with hypertension. We conducted a systematic review and updated meta-analysis to evaluate the effects of RDN on ambulatory and office blood pressures in patients with hypertension. Databases were searched up to 15 November 2023 to identify randomized, sham-controlled trials of RDN. The primary endpoint was change in 24 h ambulatory systolic blood pressure (SBP) with RDN versus sham control. The secondary endpoints were changes in 24 h ambulatory diastolic blood pressure, daytime and nighttime blood pressure (BP), office BP, and home BP. A sub-analysis determined outcomes by medication, procedure, and device. From twelve trials, 2222 patients with hypertension were randomized to undergo RDN (n = 1295) or a sham procedure (n = 927). At 2-6 months after treatment, RDN significantly reduced 24 h ambulatory SBP by 2.81 mmHg (95% confidence interval: -4.09, -1.53; p < 0.001) compared with the sham procedure. RDN also reduced daytime SBP by 3.17 mmHg (- 4.75, - 1.58; p < 0.001), nighttime SBP by 3.41 mmHg (- 4.69, - 2.13; p < 0.001), office SBP by 4.95 mmHg (- 6.37, - 3.54; p < 0.001), and home SBP by 4.64 mmHg (- 7.44, - 1.84; p = 0.001) versus the sham control group. There were no significant differences in the magnitude of BP reduction between first- and second-generation trials, between devices, or between with or without medication. These data from randomized sham-controlled trials showed that RDN significantly reduced all blood pressure metrics in medicated or unmedicated patients with hypertension, including resistant/uncontrolled hypertension.

RESUMO

This systematic review and meta-analysis included randomized controlled trials or observational studies that compare digital health interventions (DHIs) for telemedicine/telehealth versus usual care for managing blood pressure (BP) in adults. We searched PubMed, Cochrane CENTRAL, and IchuShi-Web, and used a random-effects meta-analysis of the weighted mean difference (MD) between the comparison groups to pool data from the included studies. The outcome included the pooled MD of office BP from baseline to each follow-up period. This meta-analysis considered 117 studies with 68677 participants as eligible. The 3-month intervention period reduced office systolic BP (SBP) compared with usual care in 38 studies (MD: -3.21 mmHg [95% confidence interval: -4.51 to -1.90]), with evidence of heterogeneity. Office SBP across intervention periods demonstrated comparable effects (3-, 6- [54 studies], 12- [43 studies], and >12-month periods [9 studies]). The benefits for office diastolic BP were similar to those for office SBP. Additionally, the interventions significantly reduced the office SBP compared with the control, regardless of the mode of intervention delivery (smartphone apps [38 studies], text messages [35 studies], and websites [34 studies]) or type of facility (medical [74 studies] vs. non-medical [33 studies]). The interventions were more effective in 41 hypertension cohorts compared with 66 non-hypertension cohorts (-4.81 mmHg [-6.33, -3.29] vs. -2.17 mmHg [-3.15, -1.19], P = 0.006 for heterogeneity). In conclusion, DHIs for telemedicine/telehealth improved BP management compared with usual care. The effectiveness with heterogeneity should be considered, as prudent for implementing evidence-based medicine. This meta-analysis considered 117 studies with 68677 participants eligible. The DHIs for telemedicine/telehealth reduced office BP compared with usual care, regardless of intervention duration, intervention delivery mode, facility type, and cohort type. Additionally, the DHIs reduced the risk of uncontrolled BP compared with usual care, regardless of intervention duration, intervention delivery mode, and facility type.

RESUMO

In this study, we aimed to separately evaluate the relationship between waist circumference and the incidence of hyperuricemia in men and women in the general Japanese population. We performed a population-based longitudinal study using data from the annual health examination of residents of Iki City, Japan. A total of 5567 participants without hyperuricemia at baseline were included in the analysis. The men and women were placed into groups according to the tertile of waist circumference. The outcome was incident hyperuricemia (uric acid > 416 µmol/L [7.0 mg/dL]). The relationship between waist circumference and the incidence of hyperuricemia was investigated using Cox proportional hazards models. During the follow-up period, hyperuricemia developed in 697 people (551 men and 146 women). The incidence (per 1000 person-years) of hyperuricemia increased with increasing waist circumference in the men (34.9 for tertile 1, 49.9 for tertile 2 and 63.3 for tertile 3; Ptrend < 0.001) and women (5.5 for tertile 1, 6.3 for tertile 2 and 11.9 for tertile 3; Ptrend < 0.001). Significant associations were identified after adjustment for potential confounders (men: Ptrend < 0.001; women: Ptrend = 0.014). In conclusion, both men and women with larger waist circumferences were at higher risks of subsequent hyperuricemia.

RESUMO

(1) Background: Renal dysfunction and hypertension are mutually aggravating factors; however, the details of their interaction remain unclear. In a study using renal tissue from diabetic rats, we found that ß1-integrin, a cell-substrate adhesion molecule, is specifically phosphorylated in juxtaglomerular cells that secrete renin, a blood pressure regulator. (2) Methods: A mouse juxtaglomerular cell line (As4.1 cells) was used for the following experiments: drug-induced promotion of ß1-integrin phosphorylation/dephosphorylation; knockdown of ß1-integrin and the cell adhesion molecule connexin-40 (a candidate for the main body of baroreceptor); and pressurization to atmospheric pressure + 100 mmHg. culture in hypotonic liquid medium. The expression of renin under these conditions was measured by qRT-PCR. (3) Results: Phosphorylation of ß1-integrin suppressed the expression of renin, while dephosphorylation conversely promoted it. ß1-integrin and connexin-40 knockdown both promoted the expression of renin. Pneumatic pressurization and hypotonic medium culture both decreased the expression of renin, which was restored by the knockdown of ß1-integrin. (4) Conclusions: ß1-integrin plays an inhibitory role in the regulation of the expression of renin, which may be controlled by phosphorylation and dephosphorylation. It is hypothesized that ß1-integrin and other adhesion factors regulate the expression of renin by altering the sensitivity of baroreceptors on the plasma membrane.

RESUMO

BACKGROUND: Leisure activities are believed to contribute to healthy ageing. We compared the effects of choir singing and go playing on cortisol levels in Japanese older adults. We also examined its relevance to the older adults' emotional affect and cognitive performance. METHODS: Thirty-six older adults participated either in choir or go playing, within a 2 (groups)×2 (time points) design. Dependent measures included levels of salivary cortisol, as well as key psychological, cognitive, and neuropsychological measures. RESULTS: A significant two-way interaction was observed, showing that levels of salivary cortisol decreased for the choir but increased for the go groups. The decrease in salivary cortisol for the choir group correlated with the participant's negative affect and their degree of cognitive impairment. CONCLUSION: Choir singing has the potential to reduce Japanese older adults' physiological stress. The decreases can be seen more prominently for people with stronger negative affect and cognitive impairment. Further research is required to replicate these effects.

RESUMO

Objective: The spread of coronavirus disease (COVID-19) has limited the implementation of face-to-face non-pharmacological treatment for the prevention of dementia. As a result, online non-pharmacological treatment has become increasingly important. In this study, we used an online conferencing system to implement an online version of a physical exercise program with music, and examined its effect on cognitive function. Methods: The participants were 114 healthy older adults [63 men and 51 women; mean age of 70.7 years (standard deviation = 4.6)]. Seventy-five participants were allocated to the physical exercise with music group (60 min, once a week, total 20 sessions), while the remaining 39 participants were assigned to the control group, and only underwent the examinations. In the physical exercise with music group, we performed neuropsychological examinations and brain tests both before and after the exercise program. Neuropsychological tests included the Mini-Mental State Examination, Raven's Colored Progressive Matrices (RCPM), the Rivermead Behavioral Memory Test, graphic imitation, word fluency (WF) (animal names and initial sounds), and the Trail Making Test-A/B. As an assessment of brain function, we developed an online examination of subtle cognitive decline, including tests of number and word memory, spatial grasp, the N-back task, and change inference. Results: In the N-back task, the physical exercise with music group improved significantly relative to the control group (p = 0.008). Discussion: The present findings suggest that the online version of the physical exercise with music program improved working memory, which mainly involves the frontal lobe.

RESUMO

Introduction: Due to the ongoing outbreak of the coronavirus disease 2019 (COVID-19), it is currently difficult to conduct in-person exercise classes. We thus started the program of an online physical exercise with musical accompaniment. Several interesting differences were found in the characteristics of the online participants compared with our previous in-person interventions. Participants and Methods: The total number of subjects was 88 (71.2 ± 4.9 years old; male 42, female 46). The questionnaire included the attributes of the participants, the perceived advantages of the exercise classes, and the presence or absence of noticeable changes in cognitive and physical function after participating in the classes. Results: The personal computers used to attend the online classes were operated by the participants themselves. About 42% of the participants felt that their sense of day of the week and volition were improved by attending the exercise classes for 3 months. The most frequent answer to the reason for participation was because it was free (81.8%). The second most frequent answer was because the classes were held online (75.0%). Almost half of the participants answered that they would not participate if it was held in person because of the risk of COVID-19 infection (75.0%) and the difficulty getting to the site where the exercise classes were held (59.1%). Conclusion: Online physical exercise with musical accompaniment improved the perceived orientation, volition, activity, exercise habits, and health condition in 30-40% of the participants and also stimulated greater participation by males compared to classes held in person.

RESUMO

In this real-world pilot study, we evaluated the metabolic and endocrinological effects in patients with adult growth hormone deficiency (AGHD) who switched from daily growth hormone (GH) replacement therapy to weekly GH replacement therapy using somapacitan. Eleven patients with AGHD, whose medical treatment aside from GH replacement therapy did not change, were enrolled. We investigated the metabolic and endocrinological parameters between at switching and 6 months after switching from daily GH formulation to somapacitan. The results showed that body mass index (BMI), homeostasis model assessment of insulin resistance (HOMA-IR), fasting plasma glucose (FPG), and liver functions were significantly improved 6 months after switching compared to those at switching (each P < .05). Besides, the improvement in HOMA-IR was significantly associated with the period of daily GH replacement therapy before switching (P = .048), while age, sex, improvement in BMI or liver functions, presence of any hormonal deficiency, and the existence of any hormonal replacement therapy significantly associated (P > .05). In addition, switching to GH replacement therapy did not affect endocrinological parameters. In conclusion, this study might indicate that weekly GH replacement therapy with somapacitan could have more beneficial points than daily GH replacement therapy. Considering the cohort of this study was small, future studies with larger cohorts should be necessary to confirm the results of this study.

RESUMO

Stay-at-home strategies taken during the COVID-19 pandemic changed our lifestyle drastically. Although marital status and household size are important social determinants of health that affect lifestyle, their impacts on lifestyle during the pandemic are still unclear. We aimed to evaluate the association between marital status, household size, and lifestyle changes during the first pandemic in Japan. Questionnaire surveys on lifestyle changes from before to during the first COVID-19 pandemic were conducted on October 2020 in Japan. Classified into age groups, multivariable logistic regression analysis was performed to examine the combined association of marital status and household size on lifestyle, adjusted for potential confounders including socioeconomic factors. In our prospective cohort study, 1928 participants were included. Among older participants, the singles living alone were likely to perceive more unhealthy lifestyle changes (45.8%), compared with the married (33.2%), and significantly associated with at least one unhealthy change [adjusted odds ratio (OR): 1.81, 95% confidence interval (CI): 1,18-2.78], mainly due to decreased physical activity and increased alcohol consumption. Meanwhile, the younger participants showed no significant association between marital status, household size, and unhealthy changes, while those living alone had 2.87 times higher odds of weight gain (≥ 3 kg) than the married (adjusted OR: 2.87, 95% CI: 0.96-8.54) during the pandemic. Our findings suggest that older singles living alone are potentially vulnerable subgroups to drastic social changes which warrant special attention to prevent adverse health outcomes and additional burden on health systems in the following future.

RESUMO

The aim of this study was to clarify the relationship between fasting and nonfasting serum triglyceride (TG) levels and the incidence of hypertension in a general Japanese population. We conducted a population-based retrospective cohort study using annual health check-up data of residents of Iki City, Nagasaki Prefecture, Japan. A total of 3202 participants without hypertension at baseline were included in the present analysis. TG levels were classified as quartile 1 (<0.82 mmol/L), quartile 2 (0.83-1.13 mmol/L), quartile 3 (1.14-1.70 mmol/L) and quartile 4 (≥1.71 mmol/L) for men, and as quartile 1 (<0.70 mmol/L), quartile 2 (0.71-0.96 mmol/L), quartile 3 (0.97-1.34 mmol/L) and quartile 4 (≥1.35 mmol/L) for women. The outcome was incident hypertension. During an average follow-up of 4.4 years, 983 participants developed hypertension, according to the Cox proportional hazards model. The annual incidence of hypertension increased with an elevation in TG levels for men (5.88% in quartile 1, 8.30% in quartile 2, 7.62% in quartile 3, and 9.82% in quartile 4). This association was significant, even after adjustment for other risk factors: hazard ratio 1.41 [95% CI 1.07-1.85] for quartile 2, 1.30 [0.99-1.71] for quartile 3, and 1.59 [1.22-2.08] for quartile 4 compared with quartile 1 (p = 0.041 for trend). In contrast, there was no clear association between serum TG levels and the incidence of hypertension after adjustment for confounding factors among women (p = 0.240 for trend). High levels of serum TG were associated with the future incidence of hypertension in a general population of Japanese men but were not associated with that in women. Casual serum triglyceride levels and incidence of hypertension in a general Japanese population: ISSA-CKD study.

RESUMO

OBJECTIVE: We aimed to clarify the relationship between serum alanine transaminase (ALT) levels and incidence of new-onset diabetes in a Japanese general population. SETTING: Population-based retrospective cohort study using annual health check-up data for residents of Iki City, Nagasaki Prefecture, Japan. PARTICIPANTS: A total of 5330 Japanese individuals (≥30 years old) without diabetes at baseline were analysed. PRIMARY AND SECONDARY OUTCOME MEASURES: Serum ALT levels were determined using an enzymatic method and were classified into gender-specific quartile groups as follows: group 1 (3-16 U/L in men and 3-13 U/L in women), group 2 (17-21 U/L in men and 14-16 U/L in women), group 3 (22-29 U/L in men and 17-22 U/L in women) and group 4 (30-428 U/L in men and 23-268 U/L in women). The study outcome was the incidence of diabetes (fasting glucose ≥7.0 mmol/L, non-fasting glucose ≥11.1 mmol/L, glycated haemoglobin ≥6.5% or use of glucose-lowering therapies). RESULTS: After an average follow-up period of 5.0 years, 279 individuals developed diabetes. The incidence rate of diabetes increased with elevation of serum ALT levels (0.7% per 100 person-years in group 1, 0.9% in group 2, 0.9% in group 3 and 1.7% in group 4) (p<0.001 for trend). This association was significant after adjustment for other risk factors including age, sex, obesity, hypertension, dyslipidaemia, smoking, current daily alcohol intake and regular exercise (p<0.001 for trend). Comparable associations were observed between men and women (p=0.459 for interaction). CONCLUSION: Serum ALT levels were associated with future development of diabetes in the general Japanese population.
