Longitudinal association between mental health and future antibiotic prescriptions in healthy adults: Results from the LOHAS
Objectives: To investigate the association of mental health and subjective physical functioning with future antibiotic prescriptions. Design: Prospective cohort study. Setting: A rural town in Japan. Participants: Participants who completed the baseline survey (2008-2010) of the Locomotive Syndrome and Health Outcomes in the Aizu Cohort Study (LOHAS) were recruited. Participants were limited to those without comorbidities according to the Charlson comorbidity index. Participants using antibiotics at baseline were excluded. Mental health and physical functioning were assessed using the Mental Health and Physical Functioning domains of the Short-Form 12 Health Survey, and depressive symptoms were assessed using the Mental Health Inventories at baseline. Main outcome measures: The main outcome was antibiotic prescriptions found in claims data during 1 year after the baseline survey. Results: A total of 967 participants were included in the analysis, and 151 (15.6%) participants with at least one missing variable for the confounding factors were excluded, leaving 816 participants for the primary analysis. Among the 816 participants, 65 (8.0%) were newly prescribed at least one antibiotic during the 1-year follow-up period. The most frequently prescribed antibiotics were third-generation cephalosporins (44 prescriptions; 35.5%), macrolides (28 prescriptions; 22.6%), and quinolones (23 prescriptions; 18.6%). A multivariable logistic regression analysis showed an association between higher mental health scores and future antibiotic prescriptions (adjusted odds ratio [AOR], 1.40 per 1 standard deviation [SD] increase; 95% confidence interval [CI], 1.03-1.90), whereas no significant relationship was observed between Physical Functioning scores and future antibiotic prescriptions (AOR, 0.95 per 1 SD increase; 95% CI, 0.75-1.22). During the secondary analysis, adults with depressive symptoms were less likely to be prescribed antibiotics (AOR, 0.27; 95% CI, 0.11-0.70). Conclusions: Better mental health was associated with increased future antibiotic prescriptions for healthy community-dwelling Japanese adults, suggesting that mentally healthier adults could be a target population for reducing antimicrobial use
Impact of Vonoprazan Triple-Drug Blister Packs on H. pylori Eradication Rates in Japan: Interrupted Time Series Analysis
INTRODUCTION: Helicobacter pylori eradication therapy requires a complex prescribing schedule combining clarithromycin, amoxicillin, and a proton-pump inhibitor (PPI) or potassium-competitive acid blocker (P-CAB, vonoprazan). To reduce the burden of complex prescribing and increase adherence, a vonoprazan triple-drug blister pack comprising all three medications was launched in June 2016. This study aimed to assess the impact of the combination blister pack on eradication success rate in Japan immediately after launch. METHODS: We performed an interrupted time series analysis using a large administrative claims database of 7, 300, 000 insured individuals. We identified 36, 570 patients who received first-line clarithromycin triple therapy from June 2015 to May 2016 (prelaunch) and 35, 721 who received the same therapy from July 2016 to June 2017 (post-launch). The primary outcome was the success rate of clarithromycin triple therapy and the secondary outcomes were proportion of vonoprazan use and proportion of combination blister pack use. RESULTS: The success rate of clarithromycin triple therapy increased by 2.44% (95% confidence interval [CI] 1.36-3.52; P < 0.0001) after the launch of the vonoprazan triple-drug blister pack. The proportion of vonoprazan use and proportion of combination blister pack use increased by 12.7% (95% CI 10.0-15.3; P < 0.0001) and 29.2% (95% CI 25.4-32.9; P < 0.0001), respectively. CONCLUSIONS: Launch of the vonoprazan triple-drug blister pack had a significant impact on the success rate of clarithromycin triple therapy, with greater proportions of vonoprazan and combination blister pack use. Introducing an easy-to-use formulation may be effective in changing prescribing practice and subsequent patient outcomes
Development of a preoperative prediction model for new-onset diabetes mellitus after partial pancreatectomy
ABSTRACT: Pancreatectomy is an invasive surgery that is sometimes associated with complications. New-onset diabetes mellitus sometimes develops after partial pancreatectomy and severely affects the patient's quality of life. This study aimed to develop a preoperative prediction model of new-onset diabetes mellitus after partial pancreatectomy, which will help patients and surgeons to achieve more easily better common decisions on regarding whether to perform partial pancreatectomy. This retrospective cohort study analyzed medical records of patients who underwent partial pancreatectomy (total pancreatectomy excluded) from April 1, 2008, to February 28, 2016, which were available in the database provided by Medical Data Vision Co., Ltd. (Tokyo, Japan). The predictors were preoperative age, body mass index, hemoglobin A1c level, blood glucose level, and indication for partial pancreatectomy. The outcome was the development of new-onset diabetes mellitus at 1 to 12 months after partial pancreatectomy. We used a logistic regression model and calculated the scores of each predictor. To determine test performance, we assessed discrimination ability using the receiver operating characteristic curve and calibration with a calibration plot and the Hosmer-Lemeshow test. We also performed internal validation using the bootstrap method. Of 681 patients, 125 (18.4%) had new-onset diabetes mellitus after partial pancreatectomy. The developed prediction model had a possible range of 0 to 46 points. The median score was 13, and the interquartile range was 9 to 22. The C-statistics of the receiver operating characteristic curve on the score to predict the outcome was .70 (95% confidence interval [CI], .65-.75). Regarding the test performance, the Hosmer-Lemeshow test was not significant (P = .17), and calibration was good. In the bootstrapped cohorts, the C-statistics was .69 (95% CI, .62-.76). We developed a preoperative prediction model for new-onset diabetes mellitus after partial pancreatectomy. This would provide important information for surgeons and patients when deciding whether to perform partial pancreatectomy
High-susceptibility of photosynthesis to photoinhibition in the tropical plant Ficus microcarpa L. f. cv. Golden Leaves
BACKGROUND: The tropical plant Ficus microcarpa L. f. cv. Golden Leaves (GL) is a high-light sensitive tropical fig tree in which sun-leaves are yellow and shade-leaves are green. We compared the response of photosynthetic activities to strong light between GL and its wild-type (WT, Ficus microcarpa L. f.). RESULTS: Field measurements of maximum photosystem II (PSII) efficiency (F(v)/F(m)) of intact sun-leaves in GL showed that photo synthetic activity was severely photoinhibited during the daytime (F(v)/F(m) = 0.46) and subsequently recovered in the evening (F(v)/F(m) = 0.76). In contrast, WT did not show any substantial changes of F(v)/F(m) values throughout the day (between 0.82 and 0.78). Light dependency of the CO(2) assimilation rate in detached shade-leaves of GL showed a response similar to that in WT, suggesting no substantial difference in photosynthetic performance between them. Several indicators of photoinhibition, including declines in PSII reaction center protein (D1) content, F(v)/F(m) value, and O(2) evolution and CO(2) assimilation rates, all indicated that GL is much more susceptible to photoinhibition than WT. Kinetics of PAM chlorophyll a fluorescence revealed that nonphotochemical quenching (NPQ) capacity of GL was lower than that of WT. CONCLUSION: We conclude that the photosynthetic apparatus of GL is more highly susceptible to photoinhibition than that of WT
The role of digital rectal examination for diagnosis of acute appendicitis: A systematic review and meta-analysis
Background: Digital rectal examination (DRE) has been traditionally recommendedto evaluate acute appendicitis, although several reports indicate its lack of utility for this diagnosis. No metaanalysis has examined DRE for diagnosis of acute appendicitis. Objectives: To assess the role of DRE for diagnosis of acute appendicitis. Data Sources: Cochrane Library, PubMed, and SCOPUS from the earliest available date of indexing through November 23, 2014, with no language restrictions. Study Selection: Clinical studies assessing DRE as an index test for diagnosis of acute appendicitis. Data Extraction and Synthesis: Two independent reviewers extracted study data and assessed the quality, using the Quality Assessment of Diagnostic Accuracy Studies 2 tool. Bivariate random-effects models were used for the pooled sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, and diagnostic odds ratio (DOR) as point estimates with 95% confidence intervals (CI). Main Outcomes and Measures: The main outcome measure was the diagnostic performance of DRE for diagnosis of acute appendicitis. Results: We identified 19 studies with a total of 7511 patients. The pooled sensitivity and specificity were 0.49 (95% CI 0.42-0.56) and 0.61 (95% CI 0.53-0.67), respectively. The positive and negative likelihood ratios were 1.24 (95% CI 0.97-1.58) and 0.85 (95% CI 0.70-1.02), respectively. The DOR was 1.46 (0.95-2.26). Conclusion and Relevance: Acute appendicitis cannot be ruled in or out through the result of DRE. Reconsideration is needed for the traditional teaching that rectal examination should be performed routinely in all patients with suspected appendicitis
Estimating a preference-based index from the Japanese SF-36
Objective: The main objective of the study was to estimate a preference-bascd Short Form (SF)-6D index from the SF-36 for Japan and compare it with the UK results.
Study Design and Setting: The SF-6D was translated into Japanese. Two hundred and forty-nine health states defined by this version of the SF-6D were then valued by a representative sample of 600 members of the Japanese general population using standard gamble (SG). These health-state values were modeled using classical parametric random-effect methods with individual-level data and ordinary least squares (OLS) on mean health-state values, together with a new nonparametric approach using Bayesian methods of estimation.
Results: All parametric models estimated on Japanese data were found to perform less well than their UK counterparts in terms of poorer goodness of fit, more inconsistencies, larger prediction errors and bias, and evidence of systematic bias in the predictions. Nonparametric models produce a substantial improvement in out-of-sample predictions. The physical, role, and social dimensions have relatively larger decrements than pain and mental health compared with those in the United Kingdom.
Conclusion: The differences between Japanese and UK valuations of the SF-6D make it important to use the Japanese valuation data set estimated using the nonparametric Bayesian technique presented in this article. (C) 2009 Elsevier Inc. All rights reserved
Association of kyphotic posture with loss of independence and mortality in a community-based prospective cohort study: the Locomotive Syndrome and Health Outcomes in Aizu Cohort Study (LOHAS)
[Objectives] This study aimed to investigate the association between kyphotic posture and future loss of independence (LOI) and mortality in community-dwelling older adults. [Design] Prospective cohort study. [Setting] Two Japanese municipalities. [Participants] We enrolled 2193 independent community-dwelling older adults aged≥65 years at the time of their baseline health check-up in 2008. Kyphotic posture was evaluated using the wall-occiput test (WOT) and classified into three categories: non-kyphotic, mild (>0 and ≤4 cm) and severe (>4 cm). [Primary and secondary outcome measures] The primary outcome was mortality and the secondary outcomes were LOI (new long-term care insurance certification levels 1–5) and a composite of LOI and mortality. A Cox proportional hazards model was used to estimate the adjusted HRs (aHRs). [Results] Of the 2193 subjects enrolled, 1621 were included in the primary analysis. Among these, 272 (17%) and 202 (12%) were diagnosed with mild and severe kyphotic postures, respectively. The median follow-up time was 5.8 years. Compared with the non-kyphotic group, the aHRs for mortality were 1.17 (95% CI 0.70 to 1.96) and 1.99 (95% CI 1.20 to 3.30) in the mild and severe kyphotic posture groups, respectively. In the secondary analysis, a consistent association was observed for LOI (mild: aHR 1.70, 95% CI 1.13 to 2.55; severe: aHR 2.08, 95% CI 1.39 to 3.10) and the LOI-mortality composite (mild: aHR 1.27, 95% CI 0.90 to 1.79; severe: aHR 1.83, 95% CI 1.31 to 2.56). [Conclusion] Kyphotic posture was associated with LOI and mortality in community-dwelling older adults. Identifying the population with kyphotic posture using the WOT might help improve community health
Expression of Phospho-Akt and PTEN Proteins in Human Breast Cancer in Relation to Tumor Progression and Patient Survival
Phosphatidylinositol 3-kinase (PI3-kinase) controls mitogenesis, cellular growth and transformation in a variety of cancers. The serine-threonine kinase Akt is a downstream target of PI3-kinase, and phosphorylated Akt (Phospho-Akt) inhibits apoptosis. Phosphatase and tensin homolog detected on chromosome ten (PTEN) is a tumor suppressor that antagonizes PI3-kinase activity, negatively regulates its downstream-target, Akt, inhibits phosphorylation of Akt, and medicates cell-cycle arrest and apoptosis. To clarify whether the PI3-kinase/Akt pathway and PTEN relate to breast cancer, we examined the expression of pathway-related proteins such as Phospho-Akt and PTEN in clinical specimens. Immunohistochemical analysis was performed on tissue specimens surgically obtained from 221 patients with breast cancer. The association of Phospho-Akt and PTEN expression with clinicopathological variables and the prognosis of patients were analyzed. Of 221 breast carcinomas, positive Phospho-Akt expression was observed in 91 (41.1%) and positive PTEN expression in 119 (53.8%). Phospho-Akt expression and loss of PTEN expression significantly correlated with tumor staging, tumor size and lymph node metastasis. Patients with Phospho-Akt-positive tumors had significantly inferior disease-free survival or over-all survival to those with Phospho-Akt-negative tumors, while those with PTEN positive tumors were better than those with PTEN negative tumors. Moreover, patients with Phospho-Akt-positive and PTEN-negative tumors had a significantly inferior disease-free survival and over-all survival compared to those with Phospho-Akt-negative and PTEN-positive tumors. Multivariate analysis revealed that expression of Phospho-Akt and tumor size were the independent factors (P = 0.024). We demonstrated that the expression of Phospho-Akt significantly correlated with tumor progression and patients survival with breast cancer. Phospho-Akt/PTEN expression status is possibly a definitive prognostic factor in clinical breast cancer
