Challenges faced by older people with dementia during the COVID-19 pandemic as perceived by professionals: a qualitative study with interviews.

BACKGROUND: Previous studies have highlighted a decline in the mental health of older adults over the course of the coronavirus disease 2019 (COVID-19) pandemic. Few studies have determined the possible causes of behavioural and psychological symptoms of dementia during COVID-19 in a comprehensive manner. We aimed to identify the challenges faced by older adults with dementia during the COVID-19 pandemic. METHODS: This study adopted a qualitative approach to understanding the perceptions of healthcare professionals, such as regarding the negative effects of COVID-19 on the mental health of people with dementia. Between January and March 2022, the authors conducted individual in-depth interviews on how COVID-19 affected the stress levels, care, and self-determination of people with dementia. Qualitative data from the individual interviews were data cleansed to ensure the clarity and readability of the transcripts. The qualitative data were then analyzed by inductive manual coding using a qualitative content analysis approach. The grouping process involved reading and comparing individual labels to cluster similar labels into categories and inductively formulate themes. RESULTS: Qualitative analysis extracted 61 different semantic units that were duplicated. Seven categories were inductively extracted using a grouping process. These were further integrated to extract the following four themes: fear of personal protective equipment (PPE), loneliness, dissatisfaction with behavioural restrictions and limitations of video calls, and family interference with service use. DISCUSSION: People with dementia often faced mental distress during the pandemic owing to preventive measures against COVID-19, and a lack of awareness and understanding of such preventive measures worsened their distress. They experienced a severe sense of social isolation and loneliness. Findings also indicated that families tended to ignore the needs of people with dementia and their decisions and opinions regarding healthcare service use.

Associations of overweight and obesity with the risk of cardiovascular disease according to metabolic risk factors among middle-aged Japanese workers: The Aichi Workers' cohort study.

BACKGROUND: The association between obesity and cardiovascular disease (CVD) remains unclear, particularly for those with established CVD risk factors. We analyzed follow-up data from the Aichi Workers' Cohort Study. We studied the association between the degree of obesity and risk of CVD and its subtypes specifically among individuals with hypertension, hyper-low-density lipoprotein (LDL)-cholesterolemia, or diabetes. METHODS: Pooled data of 8972 adults (7076 men and 1896 women) who were recruited between 2002 and 2008 were used in the current analysis. We used multivariable Cox proportional hazard model to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for the associations between the degree of obesity assessed with body mass index (BMI) and the risk of CVD and its subtypes, i.e., coronary heart disease (CHD) and stroke. RESULTS: During a median of 12 years, there were 197 CVDs (80 CHDs and 117 strokes). BMI ≥ 27.5 compared to 21.0-22.9 kg/m2 was positively and significantly associated with the risks of CVD, CHD, and total stroke. Hypertension, hyper-LDL-cholesterolemia, and diabetes mediated 15.9%, 5.8%, and 8.7% of obesity-CVD associations, respectively, and 28.3% by their combination. In the stratified analyses by the presence of risk factors, BMI ≥ 25.0 (overweight/obesity) compared to BMI < 25 kg/m2 was associated with a higher risk of CVD in those with and without hypertension, but only with hyper-LDL-cholesterolemia, and without diabetes. CONCLUSIONS: Overweight/obesity was associated with the risk of CVD and its subtypes. About 30% of the risk was explained by hypertension, hyper-LDL-cholesterolemia, and diabetes, of which hypertension accounted for approximately the half of the explained risk. However, overweight/obesity increased the risk of CVD even in those without hypertension. These findings highlight the importance of controlling and preventing overweight/obesity regardless of chronic disease status.

Factors influencing interprofessional collaboration in long-term care from a multidisciplinary perspective: a case study approach.

Systematic assessments of interprofessional collaboration barriers and enablers in long-term care settings are critical for delivering person-centered healthcare. However, research on factors influencing interprofessional collaboration in long-term care settings is limited. For this study, 65 healthcare professionals across multiple facilities experienced in long-term care in Japan participated in online focus group discussions and individual interviews to discuss cases. The qualitative data were analyzed using qualitative content analysis. Seven themes emerged: coordination, the need for care manager training, hierarchy among healthcare professionals, specialization but not the mind-set of overspecialization, casual conversations, electronic group communication tools, and excessive fear of personal information protection. These findings highlight the need to develop coordinator roles and for interprofessional education on the proper approach to personal information protection laws. Furthermore, daily casual conversations, the use of online platforms, and the prevention of patients being left behind due to overspecialization are required.

Pyrenoid proteomics reveals independent evolution of the CO2-concentrating organelle in chlorarachniophytes.

Pyrenoids are microcompartments that are universally found in the photosynthetic plastids of various eukaryotic algae. They contain ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) and play a pivotal role in facilitating CO2 assimilation via CO2-concentrating mechanisms (CCMs). Recent investigations involving model algae have revealed that pyrenoid-associated proteins participate in pyrenoid biogenesis and CCMs. However, these organisms represent only a small part of algal lineages, which limits our comprehensive understanding of the diversity and evolution of pyrenoid-based CCMs. Here we report a pyrenoid proteome of the chlorarachniophyte alga Amorphochlora amoebiformis, which possesses complex plastids acquired through secondary endosymbiosis with green algae. Proteomic analysis using mass spectrometry resulted in the identification of 154 potential pyrenoid components. Subsequent localization experiments demonstrated the specific targeting of eight proteins to pyrenoids. These included a putative Rubisco-binding linker, carbonic anhydrase, membrane transporter, and uncharacterized GTPase proteins. Notably, most of these proteins were unique to this algal lineage. We suggest a plausible scenario in which pyrenoids in chlorarachniophytes have evolved independently, as their components are not inherited from green algal pyrenoids.

Nonrestorative Sleep and Type 2 Diabetes Incidence: the Aichi Workers' Cohort Study.

BACKGROUND: The term "nonrestorative sleep (NRS)" refers to unrefreshed feeling at wake-up and is a domain of poor sleep quality. Previous researches have demonstrated that NRS is linked to a number of diseases and adverse health outcomes, but less is known regarding the link between NRS and diabetes, particularly in Japanese. METHODS: We studied 3665 middle-aged male participants of the Aichi Workers' Cohort Study who were followed-up from 2002 to 2019. Cox proportional hazards models estimated hazard ratios (HRs) and 95% confidence intervals (CIs) of incident type 2 diabetes mellitus (T2DM) in relation to NRS adjusted for potential confounding variables. RESULTS: During a median follow-up of 14.6 years, 421 type 2 diabetes cases were identified. Participants with NRS had a higher crude incidence rate of T2DM (11.2/1,000 person-years), compared to participants without NRS (9.3/1,000 person-years). In the fully adjusted model, individuals who reported having NRS had a significantly higher risk of developing T2DM (HR: 1.36, 95% CI: 1.10-1.67). The association was observed only in participants under 50 years old (HR: 1.82, 95% CI: 1.36-2.43), not in the older (50 years or older) participants (P for interaction =0.025). In contrast, stratified analyses by the presence of shift work, obesity or sleep duration showed similar associations in all the strata. CONCLUSIONS: NRS was associated with higher risk of T2DM in middle-aged Japanese male workers independent of a variety of lifestyle factors and other sleep problems.

Encyclopedia of Family A DNA Polymerases Localized in Organelles: Evolutionary Contribution of Bacteria Including the Proto-Mitochondrion.

DNA polymerases synthesize DNA from deoxyribonucleotides in a semiconservative manner and serve as the core of DNA replication and repair machinery. In eukaryotic cells, there are 2 genome-containing organelles, mitochondria, and plastids, which were derived from an alphaproteobacterium and a cyanobacterium, respectively. Except for rare cases of genome-lacking mitochondria and plastids, both organelles must be served by nucleus-encoded DNA polymerases that localize and work in them to maintain their genomes. The evolution of organellar DNA polymerases has yet to be fully understood because of 2 unsettled issues. First, the diversity of organellar DNA polymerases has not been elucidated in the full spectrum of eukaryotes. Second, it is unclear when the DNA polymerases that were used originally in the endosymbiotic bacteria giving rise to mitochondria and plastids were discarded, as the organellar DNA polymerases known to date show no phylogenetic affinity to those of the extant alphaproteobacteria or cyanobacteria. In this study, we identified from diverse eukaryotes 134 family A DNA polymerase sequences, which were classified into 10 novel types, and explored their evolutionary origins. The subcellular localizations of selected DNA polymerases were further examined experimentally. The results presented here suggest that the diversity of organellar DNA polymerases has been shaped by multiple transfers of the PolI gene from phylogenetically broad bacteria, and their occurrence in eukaryotes was additionally impacted by secondary plastid endosymbioses. Finally, we propose that the last eukaryotic common ancestor may have possessed 2 mitochondrial DNA polymerases, POP, and a candidate of the direct descendant of the proto-mitochondrial DNA polymerase I, rdxPolA, identified in this study.

Association of psychological factors with advanced-level functional competency: Findings from the Aichi workers' cohort study, 2002-2019.

Objective: This study examined the longitudinal association of perceived stress, ikigai, and having someone one can count on in middle age with the advanced-level functional competency in older age, which is crucial for the maintenance of independent life among older adults. The issue is especially relevant in super-aged countries like contemporary Japan, where more and more older people live in a household consisting only of older people. Methods: Data were collected in 2019 from a total of 1692 retirees of the Aichi Workers' Cohort Study participants in which baseline survey including psychological factors was conducted during their employment in 2002. Japan Science and Technology Agency Index of Competence (JST-IC) was used to measure the advanced-level functional competency. Multivariable-adjusted odds ratios (ORs) were obtained for having low JST-IC in later life by the degrees of psychological factors reported in the middle age adjusting for the presence of depressive mood in 2019. Results: Those who were not sure about ikigai (OR: 2.02, 95 % CI: 1.33 to 3.08) and who have no one to count on (OR: 2.19, 95 % CI: 1.52 to 3.16) in the middle age were significantly associated with low JST-IC after retirement. Having much stress was significantly inversely associated with a low JST-IC (OR: 0.69, 95 % CI: 0.50 to 0.97). Conclusion: Having ikigai and someone reliable, and stress during middle age might play a role in preventing impaired advanced-level functional competency. Improved ikigai and increased social interaction and support might improve functional competency. Further research might explore avenues for improving ikigai.

Good death for people living with dementia: a qualitative study.

BACKGROUND: Ensuring a good death is one of the primary objectives of palliative care and end-of-life care. There is insufficient evidence regarding what defines a good death for people living with dementia. Obtaining an understanding of what constitutes a good death could help improve dementia care. This study aimed to explore how multiple stakeholders perceive a good death for people living with dementia. METHODS: This qualitative study was carried out across six prefectures in Japan. Enrollment of participants took place within dementia outpatient clinics, hospitals, daycare centers, and community centers. A total of thirty-three in-depth interviews with people living with dementia, physicians, and nurses were conducted. Six focus group discussions were performed with family caregivers and care workers. Verbatim transcripts of the interviews were prepared, and inductive content analysis was used to examine the data. FINDINGS: Regarding the perception of a good death, the following themes were derived: (1) painless death; (2) dying in a preferred environment; (3) family's coping with loss; (4) maintaining regular life; (5) living with respect; and (6) preparation for death. All these themes are interrelated. Participants viewed a good death as a process rather than a single event. CONCLUSION: This study identifies crucial components of a good death for people living with dementia. The findings could be used to improve dementia care.

[The current role of advance care planning for people with dementia - A narrative review].

Advance care planning (ACP) for people with dementia, as with other diseases, is a necessary process to realize medical treatment and care in the final stage of a person's life. On the other hand, dementia, a disease that is expected to make it difficult for people to make decisions on their own in the future, has a long course, and is characterized by uncertainty regarding the course of the disease, which may also be a limiting factor in the implementation of ACP for people with dementia. On the other hand, the uncertainties may also be a reason for implementing ACP. This paper reviews reports on ACP initiatives for people with dementia from many countries and presents their characteristics, cultural and customary influences, effects, facilitating and inhibiting factors, and recommendations for implementation, with the aim of promoting future ACP initiatives for people with dementia. The aim of the study was to promote future ACP initiatives for people with dementia.

A Systematic Review of Qualitative Research Literature and a Thematic Synthesis of Older LGBTQ People's Experiences of Quality of Life, Minority Joy, Resilience, Minority Stress, Discrimination, and Stigmatization in Japan and Sweden.

There is a lack of research on older lesbian, gay, bisexual, transgender, and queer/questioning (LGBTQ) adults. This systematic review aimed to synthesize Japanese and Swedish qualitative research on LGBTQ adults aged 60 years or older following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Japanese and Swedish articles, published in English, were searched across ASSIA, CINAHL, Medline, PsychINFO, PubMed, Scopus, and Sociological Abstracts databases. Additional searches were conducted to include studies in Japanese or Swedish. There were no papers from Japan, whereas five from Sweden were reviewed. One article was excluded due to the wrong phenomenon. Four articles were included, involving 48 participants aged 60-94 years. We summarized the findings using a deductive thematic synthesis. Two major themes emerged: (a) quality of life, minority joy, and resilience (positive aspects), and (b) discrimination, stigmatization, and minority stress (negative aspects). The participants wished to be acknowledged for their own assets and unique life histories, and to be treated as everyone else. They emphasized the importance of knowledge of LGBTQ issues among nursing staff, so that older LGBTQ people are treated in a competent and affirmative way. The study revealed several important topics for understanding older LGBTQ adults' life circumstances and the severe lack of qualitative studies in Japan and Sweden.

New Parabasalia symbionts Snyderella spp. and Daimonympha gen. nov. from South American Rugitermes termites and the parallel evolution of a cell with a rotating "head".

Most Parabasalia are symbionts in the hindgut of "lower" (non-Termitidae) termites, where they widely vary in morphology and degree of morphological complexity. Large and complex cells in the class Cristamonadea evolved by replicating a fundamental unit, the karyomastigont, in various ways. We describe here four new species of Calonymphidae (Cristamonadea) from Rugitermes hosts, assigned to the genus Snyderella based on diagnostic features (including the karyomastigont pattern) and molecular phylogeny. We also report a new genus of Calonymphidae, Daimonympha, from Rugitermes laticollis. Daimonympha's morphology does not match that of any known Parabasalia, and its SSU rRNA gene sequence corroborates this distinction. Daimonympha does however share a puzzling feature with a few previously described, but distantly related, Cristamonadea: a rapid, smooth, and continuous rotation of the anterior end of the cell, including the many karyomastigont nuclei. The function of this rotatory movement, the cellular mechanisms enabling it, and the way the cell deals with the consequent cell membrane shear, are all unknown. "Rotating wheel" structures are famously rare in biology, with prokaryotic flagella being the main exception; these mysterious spinning cells found only among Parabasalia are another, far less understood, example.

Total pain in advanced dementia: a quick literature review.

Objective: This quick literature review aimed to organize information on the detailed components of total pain in older people with advanced dementia in a holistic manner. Materials and Methods: The authors analyzed qualitative data from relevant clinical guidelines or textbooks, focusing on certain types of pain and distress in older people with advanced dementia, followed by an expert panel review by research team members. In the search, the authors defined a person with advanced dementia as having a functional assessment staging tool scale score greater than or equal to six. Results: The model covered a wide variety of pain, from physical pain to dementia-related psychological and spiritual aspects of total pain, including living environment change, stigma, discrimination, lack of communication and understanding, loss of sense of control and dignity, and cultural distress. It also identified physical appearance as an important factor in dying with dignity, as established by existing research on individuals with incurable cancers. Conclusion: The conceptual model of total pain in people with advanced dementia is expected to help turn healthcare professionals' attention to physical, psychological, social, and spiritual contributors to total pain in advanced dementia.

Relationship Between Fasting Blood Glucose Levels in Middle Age and Cognitive Function in Later Life: The Aichi Workers' Cohort Study.

BACKGROUND: There is limited evidence regarding the relationship between Diabetes mellitus (DM) in middle age and mild cognitive impairment after a follow-up. Therefore, we investigated the relationship between fasting blood glucose (FBG) levels in middle age and cognitive function assessed using the Japanese version of the Montreal Cognitive Assessment (MoCA-J) in later life, following over 15 years of follow-up in the Aichi Workers' Cohort Study in Japan. METHODS: Participants were 253 former local government employees aged 60-79 years in 2018 who participated in a baseline survey conducted in 2002. Using baseline FBG levels and self-reported history, participants were classified into the normal, impaired fasting glucose (IFG) and, and DM groups. Total MoCA-J score ranges from 0 to 30, and cognitive impairment was defined as MoCA-J score ≤25 in this study. A general linear model was used to estimate the mean MoCA-J scores in the FBG groups, adjusted for age, sex, educational year, smoking status, alcohol consumption, physical activity, body mass index, systolic blood pressure, total cholesterol, and estimated glomerular filtration rate. RESULTS: The mean MoCA-J score in the total population was 25.0, and the prevalence of MoCA-J score ≤25 was 49.0%. Multivariable-adjusted total MoCA-J scores were 25.2, 24.8, and 23.4 in the normal, IFG, and DM groups, respectively. The odds ratio of MoCA-J score ≤25 in the DM group was 3.29. CONCLUSION: FBG level in middle age was negatively associated with total MoCA-J scores assessed later in life, independent of confounding variables.

Work and Family Conflicts, Depression, and "Ikigai": A Mediation Analysis in a Cross-cultural Study Between Japanese and Egyptian Civil Workers.

BACKGROUND: Total work-family conflicts (TWFCs) could associate with mental health, and having ikigai (a purpose of life) may mediate this association. METHODS: In a cross-cultural study of 4,792 Japanese Aichi Workers' Cohort study participants and 3,109 Egyptian civil workers, the Midlife Development in the United States (MIDUS) questionnaire measured TWFCs and the Center for Epidemiological Studies Depression (CES-D) 11-item scale measured depression. We used logistic regression models to estimate odds ratios (ORs) of having depression and a high-ikigai across levels of TWFCs (low, moderate, and high), and the PROCESS macro of Hayes to test the mediation effect. RESULTS: The prevalence of high TWFCs, depression, and having a high ikigai were 17.9%, 39.4%, and 70.1% in Japanese women, 10.5%, 26.8%, and 70.1% in Japanese men, 23.7%, 58.2%, and 24.7% in Egyptian women, and 19.1%, 38.9%, and 36.9% in Egyptian men, respectively. Compared with participants with low TWFCs, the multivariable ORs of depression in Japanese women and men with high TWFCs were 4.11 (95% confidence interval [CI], 2.99-5.65) and 5.42 (95% CI, 4.18-7.02), and those in Egyptian women and men were 4.43 (95% CI, 3.30-5.95) and 4.79 (95% CI, 3.53-6.48), respectively. The respective ORs of having a high-ikigai were 0.46 (95% CI, 0.33-0.64) and 0.40 (95% CI, 0.31-0.52) in Japanese women and men and were 0.34 (95% CI, 0.24-0.48) and 0.28 (95% CI, 0.20-0.39) in Egyptian women and men. No interaction between TWFCs and country was observed for the associations with depression or ikigai. Ikigai mediated (up to 18%) the associations between the TWFCs and depression, especially in Egyptian civil workers. CONCLUSION: TWFCs were associated with depression, and having low ikigai mediated these associations in Japanese and Egyptian civil workers.

Association of Low-Density Lipoprotein Cholesterol with Risk of Coronary Heart Disease and Stroke among Middle-Aged Japanese Workers: An Analysis using Inverse Probability Weighting.

AIMS: The associations between low-density lipoprotein cholesterol (LDL-C) and the risk of cardiovascular disease (CVD) subtypes are not well established among the Japanese population. This study used longitudinal data from the Aichi Workers' Cohort Study to explore the association between LDL-C levels and the risk of coronary heart disease (CHD) and stroke subtypes. METHODS: Pooled data of 8966 adults (7093men and 1903 women) who were recruited between (2002) and (2008) were used for the current analysis. Propensity scores for the LDL-C categories were generated using multinomial logistic regression. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated from the inverse probability weighted Cox proportional hazards model for LDL-C category associations with risks of CHD, stroke subtypes, and CVD. RESULTS: During a median follow-up of 12 years, 122 strokes (57 ischemic strokes, 25 intracerebral hemorrhage, and 40 unknown subtypes) and 82 cases of CHD were observed. LDL-C 160- mg/dL compared to LDL-C 100-119 mg/dL was positively and significantly associated with the risk of CHD (HR: 4.56; 95% CI: 1.91-10.9) but not with ischemic stroke (HR: 0.99; 95% CI: 0.44-2.22). LDL-C was inversely associated with the risk of intracerebral hemorrhage (P for trend=0.009). CONCLUSION: In middle-aged Japanese workers, LDL-C was significantly and positively associated with CHD, but not with ischemic stroke. LDL-C was inversely significantly associated with intracerebral hemorrhage.

Possible contribution of COVID-19 vaccination to the subsequent mental well-being in Japan.

The coronavirus disease 2019 (COVID-19) pandemic has had a severe impact on mental well-being. Vaccination may have played a pivotal role in enduring this mental health crisis. The present study aimed to longitudinally investigate the association between COVID-19 vaccination and mental health status among Japanese population in 2021. Longitudinal data of 17,089 individuals aged 15-79 years who participated in a nationwide online study were analyzed. Baseline and follow-up mental health statuses were assessed using the Kessler Psychological Distress Scale (K6). General linear and multivariable logistic regression models adjusted for baseline levels of mental distress were used to examine the association between vaccine receipt and follow-up levels of mental health. Mean K6 scores were lower in the vaccinated than in the non-vaccinated participants. Those who had received one or two doses of COVID-19 vaccines were associated with improved mental health at follow-up in subjects with psychological distress at baseline (odds ratio [OR] 1.31 and 1.35, respectively) and were inversely associated with deteriorated mental health status at follow-up in subjects without psychological distress at baseline (OR 0.66 and 0.70, respectively) compared with no vaccination groups, respectively. The present study would indicate that one or two doses of COVID-19 vaccinations contributed to mental well-being in Japan. This finding might provide evidence for promoting vaccination against COVID-19 and emerging infectious diseases in the future.

Text mining analysis of newspaper editorials concerning the COVID-19 pandemic from a healthcare perspective.

Objective: This pilot study aimed to examine the content of Japanese newspaper editorials concerning the coronavirus disease 2019 (COVID-19) pandemic and its change over time using text mining analysis. Materials and Methods: The authors analyzed qualitative data from the editorials of five national and 12 regional newspapers on April 7 and 8, 2020 (first state of emergency) and January 8, 2021 (second state of emergency). All analyses were conducted using KH Coder version 3. Results: The co-occurrence network showed a low level of content diversity and a high degree of politicization in the COVID-19 news coverage. The top five high frequency words from the newspapers were "infection", "declaration", "healthcare", "government", and "emergency" at the first state of emergency, and were "declaration", "measures", "government", and "restaurant" at the second one. Conclusion: The results suggest a lack of detailed information and recommendations concerning the public health challenges of the COVID-19 pandemic in Japanese newspaper editorials, even one year after the first wave of the pandemic. This study provides a data-driven foundation for the effectiveness of newspapers in COVID-19 public health communications. The extent to which the quantity and quality of information from newly emerging communication channels, such as social media, influences public understanding of public health measures remains to be established.

Palliative home care for older patients with respiratory disease in Japan: Practices and opinions of physicians.

AIM: Older adults at the end-of-life stage receiving home visits from physicians often experience symptoms such as dyspnea, pain and fatigue, among others. This study aimed to investigate the practices and opinions of physicians providing home visits regarding palliative care for older adults with respiratory symptoms due to non-malignant diseases in Japan. METHODS: A nationwide questionnaire survey on home palliative care for non-cancer chronic respiratory diseases was sent to 2988 home-care physicians in 2020 through postal mail and/or email. The questions focused on their background, their use of rating scales to evaluate the intensity of dyspnea, and their practices and opinions regarding home palliative care for respiratory diseases or symptoms. RESULTS: Valid responses were collected from 592 physicians (19.8%). A total of 251 participants (43.1%) used a rating scale to evaluate the intensity of dyspnea. While 87.8%, 86.6%, 67.3%, and 60.0% of physicians considered pulmonary rehabilitation, morphine, sedative medications, and non-invasive positive pressure ventilation (NPPV), respectively, as effective in relieving respiratory distress, 73.0%, 66.9%, 57.3%, and 55.2% of those physicians, respectively, used each modality to relieve respiratory distress. Frequently involved physicians in the aforementioned care prescribed morphine or sedative medications and used NPPV more frequently. CONCLUSIONS: This study found a discrepancy between the proportion of physicians who considered palliative care as effective and those who prescribed it. Geriatr Gerontol Int 2022; 22: 943-949.

Defining and Implementing Value-Based Healthcare for Older People from a Geriatric and Gerontological Perspective.

The world's population is ageing at a faster rate than ever before; it is estimated that there are currently over 1 billion people aged 60 years or older, mostly living in low- and middle-income countries [...].

Long-term variability and change trend of systolic blood pressure and risk of type 2 diabetes mellitus in middle-aged Japanese individuals: findings of the Aichi Workers' Cohort Study.

Studies have reported that short-term blood pressure (BP) variability (BPV) is associated with type 2 diabetes mellitus (T2DM) incidence, but the association with long-term BPV remains unclear. The present study investigated the associations of long-term BPV as well as the time trend of BP changes over time with the incidence of T2DM. This study followed a cohort of 3017 Japanese individuals (2446 male, 571 female) aged 36-65 years from 2007 through March 31, 2019. The root-mean-square error (RMSE) and the slope of systolic BP (SBP) change regressed on year were calculated individually using SBP values obtained from 2003 to baseline (2007). A multivariable Cox proportional hazard model was applied to estimate hazard ratios (HRs) and corresponding 95% confidence intervals (CIs) for tertiles of SBP RMSE and continuous SBP slopes adjusted for age, sex, smoking status, regular exercise, sodium intake, family history of diabetes, sleep disorder, body mass index (BMI), SBP, and fasting blood glucose (FBG) at baseline, and BMI slope from 2003 to 2007. The highest RMSE tertile compared to the lowest was associated with a significantly higher incidence of T2DM after adjusting for covariates (HR: 1.79, 95% CI: 1.15, 2.78). The slope was also significantly associated with T2DM incidence until baseline SBP and FBG were adjusted (HR: 1.03, 95% CI: 0.99, 1.07). In conclusion, long-term SBP variability was significantly associated with an increased incidence of T2DM independent of baseline age, sex, BMI, SBP, FBG, lifestyle factors and BMI slope from 2003 until baseline.
