RESUMO
BACKGROUND: Accurate prediction of bacteremia is essential for guiding blood culture collection and optimal antibiotic treatment. Shaking chills, defined as a subjective chill sensation with objective body shivering, have been suggested as a potential predictor of bacteremia; however, conflicting findings exist. To address the evidence gap, we conducted a systematic review and meta-analysis of studies to assess the diagnostic accuracy of shaking chills for predicting bacteremia among adult patients. METHODS: We included studies reporting the diagnostic accuracy of shaking chills or chills for bacteremia. Adult patients with suspected bacteremia who underwent at least one set of blood cultures were included. Our main analysis focused on studies that assessed shaking chills. We searched these studies through CENTRAL, MEDLINE, Embase, the World Health Organization ICTRP Search Portal, and ClinicalTrials.gov. Study selection, data extraction, evaluation for risk of bias, and applicability using the QUADAS-2 tool were conducted by two independent investigators. We estimated a summary receiver operating characteristic curve and a summary point of sensitivity and specificity of the index tests, using a hierarchical model and the bivariate model, respectively. RESULTS: We identified 19 studies with a total of 14,641 patients in which the accuracy of shaking chills was evaluated. The pooled sensitivity and specificity of shaking chills were 0.37 (95% confidence interval [CI], 0.29 to 0.45) and 0.87 (95% CI, 0.83 to 0.90), respectively. Most studies had a low risk of bias in the index test domain and a high risk of bias and a high applicability concern in the patient-selection domain. CONCLUSIONS: Shaking chills are a highly specific but less sensitive predictor of bacteremia. Blood cultures and early initiation of antibiotics should be considered for patients with an episode of shaking chills; however, the absence of shaking chills must not lead to exclusion of bacteremia and early antibiotic treatment.

PURPOSE: Little is known about the fall risk of older adults with overactive bladder, especially in the absence of urgency incontinence. We evaluated the impacts of overactive bladder with and without urgency incontinence (overactive bladder wet and overactive bladder dry) on the fall risk in older adults, and investigated the importance of overactive bladder as a predictor of falls by using tree based models. MATERIALS AND METHODS: This prospective cohort study included 630 community dwelling, independent older adults 75 years old or older who attended a health checkup in 2017 with a 1-year followup. The associations of overactive bladder dry and overactive bladder wet with a fall history, and future fall risk compared to no overactive bladder were assessed using logistic regression models. The contribution of overactive bladder as a predictor of falls was examined using a random forest and decision tree approach. RESULTS: Of the 577 analyzed participants (median age 79 years), 273 (47%) were men. The prevalence of overactive bladder dry and overactive bladder wet at baseline was 15% and 14%, respectively. Multivariable logistic regression analysis revealed that both overactive bladder dry and overactive bladder wet were associated with a higher likelihood of prior falls (adjusted ORs vs no overactive bladder 2.03 and 2.21, respectively; 95% CI 1.23-3.37 and 1.29-3.78, respectively). Among the 363 participants without a fall history, the adjusted ORs (95% CIs) of overactive bladder dry and overactive bladder wet for the occurrence of falls during the 1-year followup were 2.74 (1.19-6.29) and 1.35 (0.47-3.87), respectively. The tree based approach used for all participants showed that overactive bladder was an important predictor of falls in adults without a fall history, and the model had 83.6% accuracy and 81.8% AUC. CONCLUSIONS: Overactive bladder, even in the absence of urgency incontinence, is an important predictor of falls in older adults with a low absolute fall risk.

BACKGROUND: Acute kidney injury (AKI) is a major comorbidity in hospitalised patients. Patients with severe AKI require continuous renal replacement therapy (CRRT) when they are haemodynamically unstable. CRRT is prescribed assuming it is delivered over 24 hours. However, it is interrupted when the extracorporeal circuits clot and the replacement is required. The interruption may impair the solute clearance as it causes under dosing of CRRT. To prevent the circuit clotting, anticoagulation drugs are frequently used. OBJECTIVES: To assess the benefits and harms of pharmacological interventions for preventing clotting in the extracorporeal circuits during CRRT. SEARCH METHODS: We searched the Cochrane Kidney and Transplant Register of Studies up to 12 September 2019 through contact with the Information Specialist using search terms relevant to this review. Studies in the Register are identified through searches of CENTRAL, MEDLINE, and EMBASE, conference proceedings, the International Clinical Trials Register (ICTRP) Search Portal and ClinicalTrials.gov. SELECTION CRITERIA: We selected randomised controlled trials (RCTs or cluster RCTs) and quasi-RCTs of pharmacological interventions to prevent clotting of extracorporeal circuits during CRRT. DATA COLLECTION AND ANALYSIS: Data were abstracted and assessed independently by two authors. Dichotomous outcomes were calculated as risk ratio (RR) with 95% confidence intervals (CI). The primary review outcomes were major bleeding, successful prevention of clotting (no need of circuit change in the first 24 hours for any reason), and death. Evidence certainty was determined using the Grading of Recommendation Assessment, Development, and Evaluation (GRADE) approach. MAIN RESULTS: A total of 34 completed studies (1960 participants) were included in this review. We identified seven ongoing studies which we plan to assess in a future update of this review. No included studies were free from risk of bias. We rated 30 studies for performance bias and detection bias as high risk of bias. We rated 18 studies for random sequence generation,ÃÂ ÃÂ six studies for the allocation concealment, three studies for performance bias, three studies for detection bias,ÃÂ nine studies for attrition bias,ÃÂ 14 studies for selective reporting and nine studies for the other potential source of bias, as having low risk of bias. We identified eight studies (581 participants) that compared citrate with unfractionated heparin (UFH). Compared to UFH, citrate probably reduces major bleeding (RR 0.22, 95% CI 0.08 to 0.62; moderate certainty evidence) and probably increases successful prevention of clotting (RR 1.44, 95% CI 1.10 to 1.87; moderate certainty evidence). Citrate may have little or no effect on death at 28 days (RR 1.06, 95% CI 0.86 to 1.30, moderate certainty evidence). Citrate versus UFH may reduce the number of participants who drop out of treatment due to adverse events (RR 0.47, 95% CI 0.15 to 1.49; low certainty evidence). Compared to UFH, citrate may make little or no difference to the recovery of kidney function (RR 1.04, 95% CI 0.89 to 1.21; low certainty evidence). Compared to UFH, citrate may reduceÃÂ thrombocytopenia (RR 0.39, 95% CI 0.14 to 1.03; low certainty evidence). It was uncertain whether citrate reduces a cost to health care services because of inadequate data. For low molecular weight heparin (LMWH) versus UFH, six studies (250 participants) were identified. Compared to LMWH, UFH may reduce major bleeding (0.58, 95% CI 0.13 to 2.58; low certainty evidence). It is uncertain whether UFH versus LMWH reduces death at 28 days or leads to successful prevention of clotting. Compared to LMWH, UFH may reduce the number of patient dropouts from adverse events (RR 0.29, 95% CI 0.02 to 3.53; low certainty evidence). It was uncertain whether UFH versus LMWH leads to the recovery of kidney function because no included studies reported this outcome. It was uncertain whether UFH versus LMWH leads to thrombocytopenia. It was uncertain whether UFH reduces a cost to health care services because of inadequate data. For the comparison of UFH to no anticoagulation, one study (10 participants) was identified. It is uncertain whether UFH compare to no anticoagulation leads to more major bleeding. It is uncertain whether UFH improves successful prevention of clotting in the first 24 hours, death at 28 days, the number of patient dropouts due to adverse events, recovery of kidney function, thrombocytopenia, or cost to health care services because no study reported these outcomes. For the comparison ofÃÂ citrate to no anticoagulation,ÃÂ no completed study was identified. AUTHORS' CONCLUSIONS: Currently,ÃÂ available evidence does not support the overall superiority of any anticoagulant to another. Compared to UFH, citrate probably reduces major bleeding and prevents clotting and probably has little or no effect on death at 28 days. For other pharmacological anticoagulation methods, there is no available data showing overall superiority to citrate or no pharmacological anticoagulation. Further studies are needed to identify patient populations in which CRRT should commence with no pharmacological anticoagulation or with citrate.

AIM: The objective of this study is to assess the association of muscle mass, grip strength, and gait speed with overactive bladder (OAB) in community-dwelling elderly adults. METHODS: This cross-sectional study was based on the data collected from 350 Japanese healthy community-dwelling elderly individuals aged 75 years or older from the Sukagawa Study. Muscle mass (kg) was measured by bioelectrical impedance, whereas grip strength (kg) and gait speed (m/s) were measured by performance testing. Muscle mass and grip strength were corrected for body mass index (BMI). The primary outcome was the presence of OAB, evaluated using the OAB symptom score. RESULTS: Of the 314 participants analyzed, 146 (47%) were men and 88 (28%) presented with OAB. The mean (SD) BMI, muscle mass, grip strength, and gait speed were 23.2 (3.2) kg/m 2 , 38.4 (7.5) kg, 26.6 (8.1) kg, and 1.2 (0.2) m/s, respectively. Multivariable logistic regression analysis revealed that slower gait speed was associated with a greater likelihood of OAB (adjusted odds ratio [aOR] per -1 SD, 1.47; 95% confidence interval [CI], 1.11-1.95). No significant associations between muscle mass or grip strength and OAB were noted (aOR per -1 SD, 0.75, 1.03; 95% CI, 0.41-1.37, 0.62-1.72, respectively). Slower gait speed was also associated with higher likelihood of urgency and urgency incontinence (aOR per -1 SD, 1.35, 1.40; 95% CI, 1.04-1.74, 1.06-1.84, respectively). CONCLUSIONS: In the healthy community-dwelling elderly, gait speed was associated with OAB, including urgency and urgency incontinence. Our findings may provide a new framework for OAB management with respect to functional mobility.

Drug reaction with eosinophilia and systemic symptoms (DRESS) is a severe drug reaction characterized by skin rash, organ involvement, lymph node swelling, eosinophilia, and atypical lymphocytosis, with myocarditis being a rare but potentially fatal complication. It has been reported that in patients with cardiac involvement due to DRESS, older age and shorter periods between offending drug exposure and symptom onset are associated with mortality. We report a case of fatal DRESS-associated myocarditis in a young woman, occurring one month after drug exposure, despite intensive immunosuppressive therapy. This case report highlights the risk of mortality from DRESS-associated myocarditis even in patients lacking known risk factors.
RESUMO
Pig oocytes and embryos are highly sensitive to cryopreservation; however, tolerance to cryopreservation increases in embryos at the expanded blastocyst stage. This increased tolerance may be attributed to a decrease in cytoplasmic lipid droplets at this stage. We previously showed that an increase in the permeability of the plasma membrane in mouse oocytes to water and cryoprotectants, caused by the artificial expression of aquaporin 3, an aquaglyceroporin, enhanced tolerance to cryopreservation. In the present study, we investigated whether membrane permeability was also involved in the tolerance of pig embryos to cryopreservation. The permeability of oocytes and morulae to water and glycerol was low, whereas that of expanded blastocysts was high. Activation energy for permeability to water, glycerol, ethylene glycol, and dimethyl sulfoxide was markedly lower for expanded blastocysts than for oocytes. This suggests that water and these cryoprotectants move through expanded blastocysts predominantly by facilitated diffusion and through oocytes predominantly by simple diffusion. Aquaporin 3 mRNA was expressed in expanded blastocysts abundantly, but less so in oocytes. On the other hand, the permeability of expanded blastocysts to propylene glycol was as low as that of oocytes, and activation energy for its permeability was similar to that of oocytes, which suggests that propylene glycol moves through oocytes and embryos predominantly by simple diffusion. These results suggest that the higher tolerance of pig expanded blastocysts to cryopreservation is also related to high membrane permeability due to the expression of water/cryoprotectant channels, in addition to the decrease in cytoplasmic lipid droplets.

INTRODUCTION: Intravenous antibiotics are the primary treatment of choice for pyogenic vertebral osteomyelitis (PVO). Surgical intervention is required when the initial antibiotic treatment fails but is often difficult to perform, especially in older adults with multiple comorbidities, because of the reduced physical activity. The size of the infection signal in the spinal bone on magnetic resonance imaging (MRI) at the time of diagnosis was reported to have a high predictive accuracy for antibiotic treatment failure. However, the sample size was too small for this result to be adopted in clinical practice. Thus, we conducted a validation study of the previous research using a larger sample size. METHODS: We conducted a retrospective review of electronic medical records of patients admitted to the orthopedic department of a university hospital with a diagnosis of PVO between 2006 and 2021, and consecutively included patients without planned PVO surgery on admission and with a sagittal view of T1-weighted spinal MRI at the time of diagnosis. The index test was the percentage involvement of the affected areas in one motion segment on sagittal MRI. We also evaluated other MRI findings, such as bone destruction, segmental instability, epidural abscesses, and multiple sites for their predictive accuracy for antibiotic treatment failure. RESULTS: A total of 82 participants were eligible for the analysis. The presence of ≥90% affected area of one motion segment had a sensitivity of 16.7% and a specificity of 70.3% for future antibiotic treatment failure, resulting in poor predictive performance, with positive (LR+) and negative likelihood ratios of 0.56 and 1.19, respectively. The area under the receiver operating characteristic curve for a 10% increase in the affected area was 0.48. Among the other MRI findings, the presence of bone destruction had a significantly higher predictive accuracy (LR+ 3.11, 95% confidence interval 1.30-7.42). CONCLUSION: An infection signal ≥90% on a T1-weighted MRI of one spinal motion segment did not show sufficient predictive performance for antibiotic treatment failure. Spinal bone destruction had a mild-to-moderate predictive accuracy.
RESUMO
The rapid spread of a novel type of coronavirus infection, coronavirus disease 2019 (COVID-19) has made it difficult to implement the results of clinical trials in real-world situations. After the emergence of the Omicron variant and messenger RNA vaccine, a combination of less virulent but more contagious viruses and more people with protective immunity has resulted in a larger number of patients with less severe, mild-to-moderate COVID-19. Many patients with severe conditions did not have extensive viral pneumonia frequently seen in the "pre-Omicron" era but had serious complications due to aggravation of underlying comorbidities or secondary bacterial infections. Most clinical trials for new antiviral drugs were conducted in the "pre-Omicron" period based on a different set of background patient characteristics than the ones seen in the Omicron period. Understanding situational differences due to the gap in the timing between clinical trials and the practical use of drugs for COVID-19 will assist in developing an effective treatment strategy in real-world practice. In this seminar, we reviewed antiviral treatments for mild-to-moderate COVID-19 from the viewpoint of the difference in patient backgrounds between clinical trials and real-world studies, focusing on drugs currently used in Japan.
RESUMO
In this study, we aimed to determine whether paid work has an impact on health-related quality of life (HRQOL) among older adults. Over three years, we longitudinally collected data from 5,260 community-dwelling older adults aged 75 years or older from a city in Japan. We assessed HRQOL using the Short-Form-8. We estimated the mean difference between the physical component summary (PCS) and the mental component summary (MCS) scores, which were stratified based on gender using multivariate, generalized estimating equation models. We further conducted a subgroup analysis based on the participants' occupational backgrounds. Engagement in paid work was associated with increased MCS scores across both genders and with increased PCS scores among women. In the subgroup analysis, only women who had previously worked as managerial workers showed an inverse association with MCS scores. In this population, engagement in paid work may be a crucial factor associated with well-being.

AIM: In order to understand the digital divide among older adults during the coronavirus disease 2019 (COVID-19) pandemic, we investigated the association between internet use and compliance with COVID-19 preventive behaviors during the first state of emergency in Japan. METHODS: A total of 8952 community-dwelling citizens aged 75 years and above were asked about their preventive behaviors during the first state of emergency using a paper-based questionnaire. Among them, 51% responded and were divided into internet users and non-users. We used multivariable logistic regression models to estimate the adjusted odds ratios and 95% confidence intervals of internet use for compliance with preventive behaviors. RESULTS: Approximately 40% of the respondents used the internet, and 9.29% used social media to collect COVID-19-related information. Internet usage was independently associated with compliance with using hand sanitizers, avoiding going out, avoiding eating out, avoiding traveling, getting vaccinated, and getting tested for COVID-19; the adjusted odds ratios (95% confidence intervals) were 1.21 (1.05-1.38), 1.19 (1.04-1.37), 1.20 (1.05-1.38), 1.32 (1.15-1.52), 1.30 (1.11-1.53), and 1.23 (1.07-1.41), respectively. Exploratory subgroup analyses demonstrated that social media users might have shown early adaptation to newly recommended preventive behaviors during the first state of emergency. CONCLUSIONS: Results suggest that a digital divide exists, as evidenced by the varied compliance with preventive behaviors depending on internet use. Additionally, social media use may be associated with early adaptation to newly recommended preventive behaviors. Therefore, future studies regarding the digital divide among older adults should investigate differences depending on the types and content of internet resources.

Background and Objectives: The relationship between social isolation/loneliness and oral health is unclear. This study investigated the association between social isolation/loneliness and tooth loss in older Japanese adults. Research Design and Methods: This was a cross-sectional study of a population-based cohort (the Sukagawa Study); 5,490 cohort study participants aged ≥75 years and who were independent answered a self-administered questionnaire in 2018. Social isolation was defined based on the 6-item Japanese version of the Lubben Social Network Scale. Loneliness was measured by the 3-item Japanese version of the University of California, Los Angeles (UCLA) Loneliness Scale version 3. The primary outcome was tooth loss, defined as having fewer than 20 teeth. The secondary outcomes were decreased toothbrushing frequency and diminished ability to chew food. Prevalence ratios (PRs) were estimated using a modified Poisson regression analysis in 2 models-Model 1, which adjusted for age, gender, smoking status, alcohol consumption, low annual income, and short education period, and Model 2, which added history of depression, history of diabetes mellitus, history of stroke, and cognitive impairment to Model 1. Results: The primary analysis included 4,645 participants. Adjusted PRs of social isolation and loneliness for tooth loss (Model 1) were 0.97 (95% confidence interval [CI] 0.92-1.01) and 1.06 (95% CI 1.01-1.12), respectively; those for decreased toothbrushing frequency were 1.13 (95% CI 0.95-1.36) and 1.56 (95% CI 1.26-1.92), respectively; and those for chewing difficulty were 1.61 (95% CI 1.06-2.43) and 2.94 (95% CI 1.91-4.53), respectively. The adjusted PRs in Model 2 demonstrated results similar to that of Model 1. Discussion and Implications: Loneliness is associated with tooth loss among older adults, whereas social isolation is not. Our findings can inform plans for policymakers, professionals, and organizations to identify lonely older adults and provide social prescriptions to improve their access to oral health care services.
RESUMO
OBJECTIVE: This study aimed to evaluate the influence of advanced glycation end-product (AGE) accumulation on the prevalence and severity of overactive bladder (OAB) in community-dwelling elderly adults. METHODS: We conducted a cross-sectional study involving 269 Japanese community dwellers aged ≥75 years in 2015. AGE accumulation was non-invasively measured via skin autofluorescence (SAF) values using AGE Reader. The primary and secondary outcomes were the presence and severity of OAB evaluated using the Overactive Bladder Symptom Score (OABSS). Individuals with an urgency score of ≥2 and sum score of ≥3 were considered to have OAB. The associations of SAF with the prevalence and severity of OAB were assessed using logistic and linear regression models, respectively, adjusted for clinically important confounders. RESULTS: The median age of participants was 78 years. Of 269 participants, 110 (40.9%) were men and 75 (27.9%) had OAB. The median SAF was 2.2 arbitrary units (AUs). Increasing median SAF was observed with increasing age. Multivariable analysis revealed that SAF was not associated with either the likelihood of having OAB (odds ratio per AU=0.77, 95% confidence interval: 0.37-1.62) or the natural log-transformed OABSS (ß per AU=-0.07, 95% confidence interval: -0.26-0.12). CONCLUSIONS: In this study, AGE accumulation, as assessed by SAF, was not associated with the prevalence and severity of OAB in Japanese community-dwelling elderly people aged ≥75 years.
RESUMO
OBJECTIVES: We aimed to evaluate the characteristics, quality, and related factors of the Japanese Clinical Practice Guidelines (CPGs) published in recent years. STUDY DESIGN AND SETTING: In this cross-sectional, meta-epidemiological study, we conducted a Google search for CPGs published by 30 Japanese medical societies that are the basis for training specialties between 2018 and 2019. We used the Appraisal of Guidelines for Research & Evaluation II (AGREE II) tool and the Reporting Items for practice Guidelines in HealThcare (RIGHT) statement to evaluate the quality. RESULTS: We included 53 systematic review-based CPGs. The median score was 0.54 (IQR, 0.38-0.62) for Stakeholder involvement, 0.57 (IQR, 0.51-0.66) in Rigor of development, 0.33 (IQR 0.21-0.46) in Applicability, and 0.63 (IQR 0.46-0.73) in Editorial independence. The number of guideline developers/clinical question ratio (odds ratio [OR]: 4.14, 95% confidence interval [CI]: 1.97, 8.70) and the adopted guideline development methods (OR: 3.69, 95% CI: 1.14, 12.0) were significantly related to the Rigor of development. CONCLUSION: The quality of Japanese CPGs published in recent years remains low. Our study suggests that increasing contributors and adopting the latest guideline development methods at the beginning of the project may improve the quality of the Japanese CPGs.

BACKGROUND: To evaluate the diagnostic accuracy and clinical utility of the acute aortic dissection detection risk score (ADD-RS) alone or with D-dimer as a screening test to exclude acute aortic syndrome. METHODS: We conducted a systematic review and meta-analysis of studies examining the diagnostic accuracy of ADD-RS. We searched MEDLINE, Embase and Cochrane Controlled Register of Trials up to 12 December 2018. RESULTS: We identified nine studies involving 26,598 patients for ADD-RS alone and 3421 patients with D-dimer. Overall, the methodological quality based on the Quality Assessment of Diagnostic Accuracy Studies 2 was moderate to high. Bivariate meta-analyses showed that the pooled sensitivities were 0.94 (95% confidence interval (CI) 0.90, 0.96) at the threshold of ADD-RS ≥1, 0.46 (95% CI, 0.34, 0.59) at ADD-RS ≥2, 1.00 (95% CI 0.99, 1.00) at ADD-RS ≥1 with D-dimer and 0.99 (95% CI 0.97, 1.00) at ADD-RS ≥2 with D-dimer. For the low prevalence population, failure rate and efficiency were 0.8% and 38.3% at ADD-RS ≥1, 0.03% and 14.5% at ADD-RS ≥1 with D-dimer, and 0.1% and 33.6% at ADD-RS ≥2 with D-dimer, respectively. For the high prevalence population, failure rate and efficiency were 3.8% and 33.3% at ADD-RS ≥1, 0.2% and 12.3% at ADD-RS ≥1 with D-dimer and 0.6% and 28.4% at ADD-RS ≥2 with D-dimer, respectively. CONCLUSIONS: ADD-RS alone or with D-dimer was a useful screening test with high sensitivity to exclude acute aortic syndrome. However, the optimal threshold of ADD-RS alone or with D-dimer may depend on the clinical setting.

OBJECTIVES: The objective of the study was to assess trial-level factors associated with the contribution of individual participant data (IPD) to IPD meta-analyses, and to quantify the data availability bias, namely the difference between the effect estimates of trials contributing IPD and those not contributing IPD in the same systematic reviews (SRs). STUDY DESIGN AND SETTING: We included SRs of randomized controlled trials (RCTs) with IPD meta-analyses since 2011. We extracted trial-level characteristics and examined their association with IPD contribution. To assess the data availability bias, we retrieved odds ratios from the original RCT articles, calculated the ratio of odds ratios (RORs) between aggregate data (AD) meta-analyses of RCTs contributing IPD and those of RCTs not contributing IPD for each SR, and meta-analytically synthesized RORs. RESULTS: Of 728 eligible RCTs included in 31 SRs, 321 (44%) contributed IPD, whereas 407 (56%) did not. A recent publication year, larger number of participants, adequate allocation concealment, and impact factor ≥10 were associated with IPD contribution. We found the SRs yielded widely different estimates of RORs. Overall, there was no significant difference in the pooled effect estimates of AD meta-analyses between RCTs contributing and not contributing IPD (ROR 1.01, 95% confidence interval, 0.86-1.19). CONCLUSIONS: There was no consistent evidence of a data availability bias in recent IPD meta-analyses of RCTs with dichotomous outcomes. Higher methodological qualities of trials were associated with IPD contribution.

Objective To describe the clinical research support systems in Japanese board certification programs of internal medicine and to assess the relationship between these support systems and the scholarly activities of residents. Methods In 2018, a 26-item web questionnaire was mailed to 542 points of contact of hospitals listed as certified residency programs of internal medicine in order to obtain information about the presence of a research support system and scholarly activity from 2016. We used hospital characteristic data from the Japanese Diagnostic Procedure Combination database, a national inpatient database, and the annual report of the Japanese Society of Internal Medicine. Results A total of 228 hospitals (42%) responded to the survey. There were regular research lectures in 129 hospitals (57%), protected time (time to perform research during working hours) in 53 hospitals (23%), research consultations in 175 hospitals (77%), regular journal clubs in 213 hospitals (77%), regular research conferences in 151 hospitals (66%), data warehouses in 139 hospitals (61%), and financial research support from the hospital budget in 140 hospitals (61%). A multivariate analysis showed that none of the research support systems were related to the number of conference presentations. In contrast, protected time [odds ratio (OR) 3.66, 95% confidence interval (CI) 1.43-9.39] and regular research conferences (OR 2.20, 95% CI 1.14-4.23) were related to the presence of clinical research presentations in scientific conferences hosted by residents. Conclusion Protected time and regular research conferences were related to the scholarly activity of residents in Japanese teaching hospitals.

OBJECTIVES: Our study aimed to examine the longitudinal association between social participation and both mortality and the need for long-term care (LTC) simultaneously. DESIGN: A prospective cohort study with 9.4 years of follow-up. SETTING: Six Japanese municipalities. PARTICIPANTS: The participants were 15 313 people who did not qualify to receive LTC insurance at a baseline based on the data from the Aichi Gerontological Evaluation Study (AGES, 2003-2013). They received a questionnaire to measure social participation and other potential confounders. Social participation was defined as participating in at least one organisation from eight categories. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcomes were classified into three categories at the end of the 9.4 years observational period: living without the need for LTC, living with the need for LTC and death. We estimated the adjusted OR (AOR) using multinomial logistic regression analyses with adjustment for possible confounders. RESULTS: The primary analysis included 9741 participants. Multinomial logistic regression analysis revealed that social participation was associated with a significantly lower risk of the need for LTC (AOR 0.82, 95% CI 0.69 to 0.97) or death (AOR 0.78, 95% CI 0.70 to 0.88). CONCLUSIONS: Social participation may be associated with a decreased risk of the need for LTC and mortality among elderly patients.

As few epidemiological studies have investigated the effect of lifestyle factors on hypertension in the very elderly population, we conducted a cross-sectional study to examine the association of estimated salt intake and body weight with blood pressure in the very elderly population. We enrolled 288 participants aged 75 years or older who were residents of Sukagawa City, Fukushima Prefecture, Japan, who attended the health checkup conducted in 2015. Salt intake was estimated from spot urine samples using the Tanaka method. The mean values for age, estimated salt intake, and body weight of all participants were 79.7 years, 9.1 g/d (standard deviation 2.4 g), and 54.3 kg (standard deviation 10.2 kg), respectively. General linear models showed that salt intake and body weight were associated with higher systolic blood pressure (SBP) levels (per standard deviation higher level, adjusted difference 4.13 mm Hg [95% confidence interval 1.69-6.57] and 5.34 mm Hg [95% confidence interval 2.12-8.56], respectively). Body weight was associated with higher diastolic blood pressure (DBP) levels (per standard deviation higher level, 2.74 mm Hg [95% confidence interval 0.58-4.90]). However, salt intake was not associated with higher diastolic blood pressure levels (per standard deviation higher level, 1.15 mm Hg [95% confidence interval -0.49 to 2.79]). Our findings suggest that higher SBP is associated with both salt intake and body weight and that higher DBP is associated with body weight in the very elderly population. This study provides a rationale for lifestyle modifications to prevent hypertension as a population approach.
