Effects of the Coronavirus disease 2019 pandemic on mortality in patients with lung cancer: A multiple mediation analysis in Japan. Int J Cancer 2024. [PMID: 38794791 DOI: 10.1002/ijc.35042] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2024] [Revised: 04/20/2024] [Accepted: 05/06/2024] [Indexed: 05/26/2024]
Abstract
COVID-19 pandemic has had a substantial effect on healthcare systems worldwide, including the care of patients with lung cancer. The impact of healthcare disruptions and behavioral changes on lung cancer mortality is unclear. Patients newly diagnosed with lung cancer during the pandemic period 2020-2021 were compared with those diagnosed in the pre-pandemic 2018-2019. The primary outcome was all-cause mortality within 1 year. Cox proportional hazards regression analyses were conducted to estimate the changes in mortality between pandemic and pre-pandemic. Multiple mediation analyses were performed to determine the factors that accounted for the changes in mortality. In total, 5785 patients with lung cancer were included in this study. The overall mortality rate was significantly higher during the pandemic compared with the pre-pandemic (crude hazard ratio [HR]: 1.19, 95% confidence interval [CI]: 1.05, 1.29). Mediation analyses showed that not receiving tumor-directed treatment, diagnosis at an older age, and decreased diagnosis through cancer screening significantly accounted for 17.5% (95%CI: 4.2, 30.7), 13.9% (95%CI: 0.8, 27.0), and 12.4% (95%CI: 3.0, 21.8) of the increased mortality, respectively. This study revealed a significant increase in mortality risk in patients with lung cancer who have not received tumor-directed treatment or cancer screening, despite potential selection bias for follow-up status. Efforts should be focused on ensuring timely access to healthcare services, optimizing treatment delivery, and addressing the unique challenges faced by patients with lung cancer during the pandemic to mitigate the impact of the pandemic on lung cancer outcomes and provide clinical care to vulnerable populations.

Contralateral knee pain exacerbation after total knee arthroplasty and its impact on functional activity. Arch Orthop Trauma Surg 2024; 144:1713-1720. [PMID: 38142260 DOI: 10.1007/s00402-023-05163-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/01/2023] [Accepted: 11/26/2023] [Indexed: 12/25/2023]
Abstract
INTRODUCTION The purposes of the present study were to (1) describe the prevalence of contralateral knee pain exacerbation after total knee arthroplasty (TKA), (2) explore the risk factors for pain exacerbation, and (3) verify the association of contralateral knee pain with future functional activity. MATERIALS AND METHOD We consecutively recruited outpatients with osteoarthritis of both knees who had primary TKA planned. The contralateral knee pain using a Numerical Rating Scale (NRS) and the functional activities subdomain of the new Knee Society Knee Scoring System (KSS) were assessed preoperatively and at 1, 3, and 6 months postoperatively. Among patients with < 5 NRS points preoperatively, we described the frequency of the contralateral knee pain exacerbation, defined as a ≥ 2-point increase from preoperative pain at each postoperative visit. An exploratory analysis was performed to identify preoperative risk factors for contralateral knee pain exacerbation. A linear mixed model was fit to examine the association of the contralateral knee pain with KSS functional activities at subsequent visits. RESULTS Among 315 patients, 14.6%, 24.1%, and 27.6% of patients experienced contralateral knee pain exacerbation at 1, 3, and 6 months postoperatively, respectively. The identified preoperative risk factors were low quadriceps strength and higher Kellgren-Lawrence grade on the non-operative knee, along with severe pain on the operative knee. The magnitude of the association between contralateral knee pain and worsening KSS functional activities increased with subsequent visits (p for interaction < 0.001). CONCLUSION The frequency and impact of pain exacerbation on the contralateral knee increase after TKA and should be carefully evaluated for a prolonged period of time.

Frailty and Environmental Attributes in Older Adults: Insight from an Ecological Model. Phys Ther Res 2023; 26:71-77. [PMID: 38125292 PMCID: PMC10730123 DOI: 10.1298/ptr.r0027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2023] [Accepted: 10/26/2023] [Indexed: 12/23/2023]
Abstract
Many studies on frailty have primarily focused on individual-level risk factors such as demographics and lifestyle. While guidelines for frailty management recommend modifications to an individual's lifestyle, their lifestyle behaviors are significantly influenced by their surroundings. Recently, the association between frailty and environmental attributes has drawn attention as a result of the increase in evidence that multiple factors affect health conditions and behaviors associated with frailty. These findings can be organized based on an ecological model involving five nested levels that influence an individual's behaviors, namely, an intrapersonal/individual core (age, education, and attitude), an interpersonal level (persons and groups), an organizational/institutional level (organization and workplace), a community level (natural, built, and social environments), and a system/public policy level (public policies from local to national). This study reviewed possible factors associated with frailty from the onset and its progression at each level of the ecological model and their implications regarding frailty prevention. Additionally, we introduce a policy-level approach for frailty prevention in Japan-which encourages residents to engage in the local society by participating in community places or groups that are referred to as "Kayoi-no-ba"-and aggregate its status from a government report. This perspective on community building is consistent with the concept of an ecological model. However, few studies have verified the effects of policy- or system-level approaches on disability and frailty prevention. Further studies from an ecological perspective are needed to fulfill multilevel interventions for frailty prevention.

Impact of the COVID-19 pandemic on the mortality among patients with colorectal cancer in Hiroshima, Japan: A large cancer registry study. Cancer Med 2023; 12:20554-20563. [PMID: 37877230 PMCID: PMC10660096 DOI: 10.1002/cam4.6630] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2023] [Revised: 09/21/2023] [Accepted: 10/04/2023] [Indexed: 10/26/2023] Open
Abstract
BACKGROUND This retrospective cohort study aimed to evaluate the impact of the COVID-19 pandemic on colorectal cancer care and mortality using a large cancer registry in Hiroshima Prefecture, Japan. The study aimed to estimate the all-cause mortality rates within 1 year of diagnosis among colorectal cancer patients diagnosed during the pandemic period (2020 and 2021) compared to those diagnosed during the pre-pandemic period (2018 and 2019). METHODS The day of diagnosis was set as Day 0 and Cox regression models were utilized to estimate crude hazard ratios (HRs) and adjusted HRs, accounting for age, sex, cancer stage, and treatment status. Two sensitivity analyses of overall survival were performed with different cutoffs of the pre-pandemic/pandemic periods and year-to-year comparisons. Subgroup analyses were performed using likelihood ratio tests. RESULTS A total of 15,085 colorectal cancer patients were included, with 6499 eligible for follow-up. A median age of included patients was 72 years old, of which 59% were male. The distribution of cancer stages showed little variation between the pre-pandemic and pandemic periods. With a median follow-up of 177 days, the number of events was 316/3111 (173 events per 1000 person-years [E/1000PY], 95% confidence interval [CI]: 154-192 E/1000PY) in the pre-pandemic period, and 326/2746 (245 E/1000PY, 95% CI: 220-274 E/1000PY) in the pandemic period (crude HR: 1.42, 95% CI: 1.22-1.66; adjusted HR: 1.25, 95% CI: 1.07-1.46). The two sensitivity analyses and subgroup analyses consistently supported these findings. CONCLUSIONS The study revealed an increased colorectal cancer mortality during the pandemic period, suggesting a continuous impact of the COVID-19 pandemic on the known and unknown risk factors for colorectal cancer for several years. Further studies are necessary to mitigate the adverse effects on patient outcomes.

Development and internal validation of a screening tool for chronic prostatitis (S-CP). World J Urol 2023; 41:2759-2765. [PMID: 37712967 PMCID: PMC10582131 DOI: 10.1007/s00345-023-04574-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2023] [Accepted: 08/10/2023] [Indexed: 09/16/2023] Open
Abstract
PURPOSE We developed a simple self-checkable screening tool for chronic prostatitis (S-CP) and internally validated it to encourage men (in the general population) with possible chronic prostatitis to consult urologists. METHODS The expert panel proposed the S-CP, which comprises three domains: Area of pain or discomfort (6 components), accompanying Symptom (6 components), and Trigger for symptom flares (4 components). We employed logistic regression to predict chronic prostatitis prevalence with the S-CP. We evaluated the predictive performance using data from a representative national survey of Japanese men aged 20 to 84. We calculated the optimism-adjusted area under the curve using bootstrapping. We assessed sensitivity/specificity, likelihood ratio, and predictive value for each cutoff of the S-CP. RESULTS Data were collected for 5,010 men-71 (1.4%) had a chronic prostatitis diagnosis. The apparent and adjusted area under the curve for the S-CP was 0.765 [95% confidence interval (CI) 0.702, 0.829] and 0.761 (0.696, 0.819), respectively. When the cutoff was two of the three domains being positive, sensitivity and specificity were 62.0% (95% CI 49.7, 73.2) and 85.4% (95% CI 84.4, 86.4), respectively. The positive/negative likelihood ratios were 4.2 (95% CI 3.5, 5.2) and 0.45 (95% CI 0.33, 0.60), respectively. The positive/negative predictive values were 5.7 (95% CI 4.2, 7.6) and 99.4 (95% CI 99.1, 99.6), respectively. CONCLUSION The reasonable predictive performance of the S-CP indicated that patients (in the general population) with chronic prostatitis were screened as a first step. Further research would develop another tool for diagnostic support in actual clinical settings.

Prehospital shock index predicts 24-h mortality in trauma patients with a normal shock index upon emergency department arrival. Am J Emerg Med 2023; 70:101-108. [PMID: 37267676 DOI: 10.1016/j.ajem.2023.05.008] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2022] [Revised: 04/19/2023] [Accepted: 05/04/2023] [Indexed: 06/04/2023] Open
Abstract
BACKGROUND The shock index (heart rate divided by systolic blood pressure) of trauma patients upon emergency department arrival predicts blood loss and death. However, some patients with normal shock indices (0.4 < shock index <0.9) upon emergency department arrival also have poor prognoses. This study aimed to determine whether abnormal prehospital shock indices in trauma patients with normal shock indices upon emergency department arrival were predictors of a high risk of mortality. METHODS We conducted a retrospective cohort study of emergency department-admitted trauma patients from 2004 to 2017. The study included 89,495 consecutive trauma patients aged ≥16 years, with Abbreviated Injury Scale score of ≥3, who were transported to the emergency department directly from the field and had a normal shock index upon emergency department arrival. According to the prehospital shock index scores, the patients were categorized into low shock index (≤ 0.4), normal shock index, and high shock index (≥0.9) groups. Odds ratios and 95% confidence intervals were calculated using logistic regression analysis. RESULTS The 89,495 patients had a median age of 64 (interquartile range: 43-79) years, and 55,484 (62.0%) of the patients were male. There were 1350 (1.5%) 24-h deaths in total; 176/4263 (4.1%), 1017/78,901 (1.3%), and 157/6331 (2.5%) patients were in the low, normal, and high prehospital shock index groups, respectively. The adjusted odds ratios for 24-h mortality compared with the normal shock index group were 1.63 (95% confidence interval: 1.34-1.99) in the low shock index group and 1.62 (95% confidence interval: 1.31-1.99) in the high shock index group. CONCLUSION Trauma patients with abnormal prehospital shock indices but normal shock indices upon emergency department arrival are at a higher risk of 24-h mortality. Identifying these indices could improve triage and targeted care for patients.

Abstract
BACKGROUND Due to potentially fatal consequences of missed bacteremia, blood cultures are often overused. While there are several prediction models that can be used to identify patients who truly need blood cultures, physicians often rely on their gestalt. We evaluated the diagnostic performance of physician gestalt for bacteremia in comparison with 2 existing prediction models: Takeshima and Shapiro. METHODS The study enrolled consecutive adult patients with suspected infection who were in the process of being admitted to the general medicine department at 2 hospitals between April 2017 and January 2019. Attending physicians provided gestalt regarding risk of bacteremia (0%-100%). Patients with a <10% risk estimated via each strategy (ie, physician gestalt or 2 existing models) were categorized as bacteremia excluded (ie, blood cultures were considered unnecessary). Strategies were compared in terms of safety (proportion of patients with bacteremia among those classified as bacteremia excluded) and efficiency (proportion of patients classified as bacteremia excluded among the total cohort). RESULTS Among 2014 patients, 292 (14.5%) were diagnosed with bacteremia. The safety of physician gestalt and the Takeshima and Shapiro models was 3.7% (95% confidence interval [CI], 2.2% to 5.7%), 6.5% (95% CI, 5.0% to 7.9%), and 10.8% (95% CI, 9.4% to 12.3%), whereas the efficiency of each strategy was 22.4% (95% CI, 22.5% to 26.3%), 52.7% (95% CI, 50.5% to 54.9%), and 87.8% (95% CI, 86.3% to 89.2%), respectively. CONCLUSIONS Physician gestalt was safer but less efficient than existing models. Clinical prediction models could help reduce the overuse of blood cultures.

Abstract
BACKGROUND Whether the lower phase angle associated with worse physical function is a result of pain and muscle weakness in patients with lumbar spinal stenosis (LSS) is unclear. OBJECTIVE To evaluate the association between phase angle and back pain-specific disabilities in patients with LSS. METHODS In this single-center, cross-sectional study, 491 participants with LSS were enrolled. The phase angle and back pain-specific disability were measured using bioelectrical impedance analysis and the Oswestry Disability Index, respectively. General linear models were used to examine associations between phase angle and the Oswestry Disability Index with or without adjustment for age, sex, low back and lower limb pain, numbness in the lower extremities, total fat mass, and lower limb muscle mass. RESULTS The mean (SD) phase angle was 4.4∘ (1.0∘), and the mean Oswestry Disability Index was 36.1 (14.1) points. Greater phase angles were associated with less Oswestry Disability Index points (p= 0.037) independent of fat mass, low back pain, and hip or lower limb pain. CONCLUSIONS A lower phase angle was associated with worse functional disability. Low phase angle may be an indicator of functional impairment due to low back pain associated with LSS.

Bacterial susceptibility change post national shortage of first cephalosporin in Japan; a longitudinal retrospective database study using interrupted time series analysis. J Glob Antimicrob Resist 2022; 30:348-353. [PMID: 35732262 DOI: 10.1016/j.jgar.2022.06.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2022] [Revised: 06/10/2022] [Accepted: 06/13/2022] [Indexed: 11/26/2022] Open
Abstract
OBJECTIVES The clinical evidence for the impact of narrow-spectrum antimicrobial shortages on bacterial susceptibility is limited. Our purposes were to determine the impacts of the disruption of most of the Cefazolin (CEZ) supply in Japan on the susceptibility of pathogens and to analyze how long these changes persisted after the shortage of CEZ. METHODS We performed an interrupted time series analysis using the Japanese Infectious Disease Nationwide database. We analyzed each pathogen before and after CEZ shortage in 52 university hospitals from 2018 to 2020. May to November 2019 was designated as the implementation term for CEZ shortage. The primary outcome was the susceptibility to CEZ and other antimicrobial agents. Among all pathogens isolated from facilities, we identified pathogens that were tested for susceptibility to CEZ. RESULTS Of the 26 pathogens identified, analysis was performed on a total of 36346 isolates of five pathogens (E.coli, K.pneumoniae, K.oxytoca, P.mirabillis, S.aureus). Among four gram negative pathogens with low susceptibility, there were no significant immediate changes after the CEZ shortage, however, the slope change significantly increased by 1.29-2.69% per month and continued to improve 1 year after the shortage. Regarding S. aureus, which was highly susceptible at the baseline, neither immediate change nor slope was significant. CONCLUSIONS This quasi-experimental analysis using nationwide large database revealed that restriction of use due to narrow antimicrobial shortages may lead to improved susceptibility over the subsequent year. The results suggest that temporary switching of antimicrobial agents on a national scale could be effective.

Abstract
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.

Abstract
BACKGROUND Solitary death is an emerging public health problem in developed countries. Alcohol abuse is associated with social isolation and excess mortality. However, data on the association between alcohol abuse and solitary death are limited. Our purposes were to assess whether alcohol abuse is associated with a long interval from death to discovery among people living alone. METHODS This is a cross-sectional study using the data on subjects from the largest forensic database in Kyoto, Japan, from February 2012 to December 2015. Solitary death was defined as a phenomenon of dying alone at home and remaining undiscovered for more than 1 week. All the subjects who lived alone and aged over 18 at the time of death were included in the study. The presence of alcohol abuse was identified via an investigation during home visits. Proportional ratios were calculated using a fitted logit model to evaluate the association of alcohol abuse on solitary death after adjusting for possible confounders. RESULTS A total of 235 subjects were included in the analysis. The mean age (standard deviation) of subjects at the time of death was 63.4 (15.1) years, and approximately 61.8% and 38.9% of subjects in the alcohol and non-alcohol abuse groups, respectively, experienced solitary death. Multivariable analyses revealed that alcohol abuse was associated with solitary death (adjusted proportion ratio: 1.50; 95% confidence interval: 1.12-2.00). CONCLUSIONS The findings of this study could help identify individuals at higher risk of solitary death. Moreover, calling the attention of people with alcohol abuse may be beneficial to prevent solitary death.

Abstract
AIMS To develop and internally validate a preoperative clinical prediction model for acute adjacent vertebral fracture (AVF) after vertebral augmentation to support preoperative decision-making, named the after vertebral augmentation (AVA) score. METHODS In this prognostic study, a multicentre, retrospective single-level vertebral augmentation cohort of 377 patients from six Japanese hospitals was used to derive an AVF prediction model. Backward stepwise selection (p < 0.05) was used to select preoperative clinical and imaging predictors for acute AVF after vertebral augmentation for up to one month, from 14 predictors. We assigned a score to each selected variable based on the regression coefficient and developed the AVA scoring system. We evaluated sensitivity and specificity for each cut-off, area under the curve (AUC), and calibration as diagnostic performance. Internal validation was conducted using bootstrapping to correct the optimism. RESULTS Of the 377 patients used for model derivation, 58 (15%) had an acute AVF postoperatively. The following preoperative measures on multivariable analysis were summarized in the five-point AVA score: intravertebral instability (≥ 5 mm), focal kyphosis (≥ 10°), duration of symptoms (≥ 30 days), intravertebral cleft, and previous history of vertebral fracture. Internal validation showed a mean optimism of 0.019 with a corrected AUC of 0.77. A cut-off of ≤ one point was chosen to classify a low risk of AVF, for which only four of 137 patients (3%) had AVF with 92.5% sensitivity and 45.6% specificity. A cut-off of ≥ four points was chosen to classify a high risk of AVF, for which 22 of 38 (58%) had AVF with 41.5% sensitivity and 94.5% specificity. CONCLUSION In this study, the AVA score was found to be a simple preoperative method for the identification of patients at low and high risk of postoperative acute AVF. This model could be applied to individual patients and could aid in the decision-making before vertebral augmentation. Cite this article: Bone Joint J 2022;104-B(1):97-102.

Abstract
Background Although corticosteroid therapy with dose tapering is the most commonly used treatment for acute exacerbation of idiopathic pulmonary fibrosis (AE-IPF), there is no consensus on the tapering regimen. This study aimed to investigate the association between early corticosteroid dose tapering and in-hospital mortality in patients with AE-IPF. Methods In this retrospective cohort study, we analyzed the data of a cohort from eight Japanese tertiary care hospitals and routinely collected administrative data from a cohort from 185 Japanese hospitals. Patients with AE-IPF were classified into the early and non-early tapering groups depending on whether the maintenance dose of corticosteroids was reduced within two weeks of admission. Propensity score analysis with inverse probability weighting (IPW) was performed to estimate the effect of early corticosteroid dose tapering. Results The multi-center cohort included 153 eligible patients, of whom 47 (31%) died, whereas the administrative cohort included 229 patients, of whom 51 (22%) died. Patients with early tapering tended to have a better prognosis than those without it (unadjusted hazard ratio [95% confidence interval] 0.41 [0.22–0.76] and 0.65 [0.36–1.18] in the multi-center and administrative cohorts, respectively). After IPW, the early tapering group had a better prognosis than the non-early tapering group (IPW-adjusted hazard ratio [95% confidence interval] 0.37 [0.14–0.99] and 0.27 [0.094–0.83] in the multi-center and administrative cohorts, respectively). Conclusion Early corticosteroid dose tapering was associated with a favorable prognosis in patients with AE-IPF. Further studies are warranted to confirm the effects of early corticosteroid dose tapering in patients with AE-IPF.

Primary care physicians' perceptions concerning engagement in cancer survivor care. J Gen Fam Med 2021; 23:149-157. [PMID: 35509332 PMCID: PMC9062547 DOI: 10.1002/jgf2.515] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2021] [Revised: 10/19/2021] [Accepted: 12/06/2021] [Indexed: 12/05/2022] Open
Abstract
Background Given the growing diversity among cancer survivors and the fact that oncologists typically do not perform long‐term care, the expected role of primary care physicians (PCPs) in survivor care is expanding. However, communication and collaboration between oncologists and PCPs are lacking. Therefore, we assessed the perception of cancer survivor care among PCPs. Methods We sent a questionnaire to 767 Japanese Board–certified PCPs, regardless of facility type (clinics and hospitals), inquiring about PCPs' perceptions of their role in survivor care. Additionally, we included vignette‐based scenarios focused on colorectal and prostate cancer survivors to explore factors associated with their clinical decisions. Results We obtained 91 replies (response rate: 11.9%). A total of 75% of PCPs had encountered at least 1 cancer patient in actual practice. Even for patients actively receiving cancer treatment, >70% of PCPs reported that they were willing to engage in comprehensive survivor care, except for the administration of anticancer drugs. Further, 49% of PCPs considered that both PCPs and oncologists were suited to performing regular screening for cancer recurrence in high‐risk patients. Multivariable logistic regression analyses revealed that clinic PCPs were less inclined to conduct screening for recurrence than hospital PCPs in both colorectal (odds ratio, 3.85 [95% confidence interval 1.40–10.6]) and prostate (4.36 [95% confidence interval 1.51–12.6]) cancer scenarios. Conclusions Our findings suggest that Japanese PCPs are willing to engage in survivor care and encourage closer collaboration between oncologists and PCPs. However, oncologists might need to request cooperation, considering the facility type with which PCPs are affiliated. The present study revealed that Japanese primary care physicians (PCPs) were willing to engage in comprehensive survivor care, except for the administration of anticancer drugs. Further, most PCPs were willing to engage in psychosocial support to relieve survivors' anxiety and manage work‐related issues, but they have few opportunities to collaborate with oncologists. Oncologists and PCPs need to engage in more communication and conduct cancer survivor care while capitalizing on PCPs' willingness and capability.![]()

Abstract
PURPOSE There is a paucity of data on the effect of intraoperative end-tidal carbon dioxide (EtCO2) levels on postoperative mortality. The purpose of this study was to investigate the relationship between intraoperative EtCO2 and 90-day mortality in patients undergoing major abdominal surgery under general anesthesia. METHODS We conducted a historical cohort study of patients undergoing major abdominal surgery under general anesthesia at Kyoto University Hospital. We measured the intraoperative EtCO2, and patients with a mean EtCO2 value < 35 mm Hg were classified as low EtCO2. The time effect was determined based on minutes below an EtCO2 of 35 mm Hg, and cumulative effects were evaluated by measuring the area under the threshold of 35 mm Hg for each patient. RESULTS Of 4,710 patients, 1,374 (29%) had low EtCO2 and 55 (1.2%) died within 90 days of surgery. Multivariable Cox regression analysis-adjusted for age, American Society of Anesthesiologists Physical Status classification, sex, laparoscopic surgery, emergency surgery, blood loss, mean arterial pressure, duration of surgery, type of surgery, and chronic obstructive pulmonary disease-revealed an association between low EtCO2 and 90-day mortality (adjusted hazard ratio, 2.2; 95% confidence interval [CI], 1.2 to 3.8; P = 0.006). In addition, severity of low EtCO2 was associated with an increased 90-day mortality (area under the threshold; adjusted hazard ratio; 2.9, 95% CI, 1.2 to 7.4; P =0.02); for long-term exposure to an EtCO2 < 35 mm Hg (≥ 226 min), the adjusted hazard ratio for increased 90-day mortality was 2.3 (95% CI, 0.9 to 6.0; P = 0.08). CONCLUSION A mean intraoperative EtCO2 < 35 mm Hg was associated with increased postoperative 90-day mortality.

Abstract
STUDY DESIGN This prospective cohort study analyzed data from the Locomotive Syndrome and Health Outcomes in the Aizu Cohort Study. OBJECTIVE To investigate the association between lumbar spinal stenosis (LSS) and severe disability and mortality among community-dwelling older adults. SUMMARY OF BACKGROUND DATA Only a few studies have investigated LSS longitudinally, and the study participants were limited to selected patients diagnosed with LSS during a hospital visit. Additionally, the prognosis of LSS remains unclear. METHODS We enrolled independent community-dwelling older adults aged 65 years or older at the time of a baseline health checkup in 2008. LSS was diagnosed using a validated diagnostic support tool for LSS. The primary endpoint was a composite of severe disability (long-term care insurance certification grade 4 or 5) and mortality. We used 1 minus Kaplan-Meier failure estimates and the log-rank test to compare the interval between baseline and the predetermined endpoint as well as a Cox proportional hazards model to estimate hazard ratios (HRs) for the LSS group with adjustment for possible confounders. Multiple imputation by chained equations was performed for sensitivity analysis. RESULTS Of 2058 subjects enrolled, 1560 did not have missing covariates; 269 (17%) were diagnosed with LSS. After a median follow-up of 5.8 years, the rates of severe disability and mortality were 0.022 per year in subjects with LSS and 0.012 per year in those without (P = 0.006). The adjusted HR for the composite endpoint in the LSS group was 1.55 (95% confidence interval [CI], 1.01-2.38). A similar association was observed after multiple imputation of missing covariates (adjusted HR, 1.51 [95% CI, 1.06-2.16]). CONCLUSION LSS was associated with severe disability and mortality in community-dwelling older adults. Detection of adults with LSS in the community may contribute to local health promotion.Level of Evidence: 2.

Impact of Vonoprazan Triple-Drug Blister Packs on H. pylori Eradication Rates in Japan: Interrupted Time Series Analysis. Adv Ther 2021; 38:3937-3947. [PMID: 34091865 PMCID: PMC8280045 DOI: 10.1007/s12325-021-01784-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2021] [Accepted: 05/07/2021] [Indexed: 10/31/2022]
Abstract
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.

Abstract
AIM To clarify the association of poor oral function with loss of independence (LOI) or death in functionally independent older adults in the community. METHODS We conducted a secondary analysis of data from a prospective cohort study in two municipalities in Japan. We included participants who were older than 65 years of age and had no certification in long-term care at baseline. Poor oral function was evaluated by the Kihon Checklist. Among participants with poor oral function, they were further classified by the degree of quality of life (QOL) impairment due to dysphagia. Main outcome is LOI or death from all cause. The hazard ratio (HR) and 95% confidence of intervals (CIs) were estimated by Cox proportional hazard models adjusted for potential confounders. RESULTS Of 1,272 participants, 150 participants (11.8%) had poor oral function. The overall incidence of LOI or death was 10.0% in the participants with poor oral function, while 3.3% in the participants without. Participants with poor oral function were more likely to develop LOI or death than those without (crude HR = 3.17 [95% CIs 1.74-5.78], adjusted HR = 2.30 [95% CIs 1.22-4.36]). 10 participants (0.79%) were classified as poor oral function with QOL impairment, and were more likely to develop LOI or death than those without poor oral function (crude HR = 7.45 [95% CIs 1.80-30.91], adjusted HR = 8.49 [95% CIs 1.88-38.34]). CONCLUSIONS Poor oral function was associated with higher risk of LOI or death in functionally independent older adults in the community.

Abstract
BACKGROUND Although polypharmacy is known to cause side-effects due to drug-drug interactions, dermatological symptoms triggered by polypharmacy are not fully addressed. OBJECTIVE To investigate whether polypharmacy is associated with the risk of pruritus. METHOD A cohort study was performed to examine cross-sectional and longitudinal relationships between polypharmacy and pruritus in a general population. Data were collected from the Norm Study conducted in 2016 and 2017, which is a nationwide survey based on a self-administered questionnaire with Japanese representative participants aged 16-84 years. Presence of polypharmacy which was defined as concurrent use of ≥5 prescribed drugs. Primary outcomes were the presence of severe pruritus at baseline for the cross-sectional analysis and the development of severe pruritus after one year for the longitudinal analysis. Multivariable modified Poisson regression analyses were performed to estimate risk ratios (RRs) and 95% confidence intervals (95%CIs) with adjustment for potential confounders (age, gender, smoking habits, drinking habits, depressive symptoms, moderate activities based on IPAQ score and presence of 11 comorbid conditions including skin disease). RESULTS The study included 3126 participants (mean age, 48.7 years); nearly half (49.8%) were male. In all, 332 participants (10.3%) had polypharmacy in the cross-sectional analysis. Participants with polypharmacy were more likely to present with severe pruritus at baseline than those who were not using drugs (adjusted RR = 1.52 [95%CI 1.15-2.01, P = 0.003]). The longitudinal analysis (n = 1803) was limited to those without severe pruritus at baseline; participants with polypharmacy at baseline were more likely to develop severe pruritus after a one-year follow-up period than those not using drugs (adjusted RR = 1.46 [95%CI 1.14-1.87, P = 0.002]). CONCLUSION Polypharmacy was associated with the presence of pruritus at baseline and may predict the future risk of developing pruritus.

Inverse Association Between Fatty Liver at Baseline Ultrasonography and Remission of Type 2 Diabetes Over a 2-Year Follow-up Period. Clin Gastroenterol Hepatol 2021; 19:556-564.e5. [PMID: 32565288 DOI: 10.1016/j.cgh.2020.06.032] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/24/2020] [Revised: 06/07/2020] [Accepted: 06/11/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS Improvement of fatty liver may be required for remission of type-2 diabetes. However, there is no longitudinal evidence on whether fatty liver reduces the chances for remission of type-2 diabetes. We investigated the association between fatty liver and remission of type-2 diabetes (the primary analysis), and also the association between improvement of fatty liver and remission of type-2 diabetes (the secondary analysis). METHODS We collected data from 66961 people who underwent screening for type-2 diabetes from 2008 through 2016 at a single center in Japan. The primary analysis included 2567 patients with type-2 diabetes without chronic renal failure or a history of hemodialysis who underwent ultrasonography to detect fatty liver, all of whom had follow-up testing, including blood testing, for a median 24.5 months after the baseline ultrasonography. The secondary analysis included 1833 participants with fatty liver at baseline who underwent a second ultrasonography, and participants who had fatty liver at baseline but not at the second visit were considered to have had improvement of fatty liver. Remission of type-2 diabetes was defined as a fasting plasma glucose level below 126 mg/dL and an HbA1c level below 6.5% for more than 6 months without anti-diabetic drugs. Odds ratios (ORs) of remission of type-2 diabetes were estimated using logistic-regression models. RESULTS A lower proportion of patients who had fatty liver detected by ultrasonography at baseline (8.7%, 167/1910) had remission of type-2 diabetes during the follow-up period than patients without fatty liver (13.1%, 86/657). Fatty liver at baseline was associated with a lower odds of remission of type-2 diabetes (multivariable-adjusted OR, 0.51; 95% CI, 0.37-0.72). A higher proportion of patients who had improvement of fatty liver had remission of type-2 diabetes (21.1%, 32/152) than patients with no improvement of fatty liver (7.7%, 129/1681). Improvement of fatty liver was associated with a higher odds of remission of type-2 diabetes (multivariable-adjusted OR, 3.08; 95% CI, 1.94-4.88). CONCLUSIONS Over a follow-up period of approximate 2 years, remission of type-2 diabetes was less common in people with fatty liver detected by ultrasonography, and improvement of fatty liver was independently associated with type-2 diabetes remission.

Abstract
BACKGROUND/OBJECTIVE Reduction of muscle markers, such as creatine phosphokinase (CK), in rheumatic diseases and its association with reduced muscle mass may be of clinical importance in osteoarthritis (OA). Considering the complexity of secondary sarcopenia, clarifying the association between muscle markers and sarcopenia and disentangling the involvement of OA-related conditions are of clinical importance. We investigated the association between serum muscle biomarkers and sarcopenia among patients with OA, considering the presence of pain and inflammation. METHODS Overall, 1425 patients with knee and hip OA scheduled for joint replacement surgery were included in a single-center cross-sectional study from Screening for People Suffering Sarcopenia in Orthopedic cohort of Kobe study. Primary outcome was sarcopenia defined by 2 criteria (the Asian Working Group for Sarcopenia and the European Working Group on Sarcopenia in Older People). Pain and inflammation were measured using the numeric rating scale and serum C-reactive protein (CRP) levels, respectively. Associations between the biomarkers (serum CK, aspartate aminotransferase, alanine aminotransferase) and sarcopenia were examined using logistic regression models. RESULTS Sarcopenia by the Asian Working Group for Sarcopenia criteria was present in 4.0% of patients. In adjusted analyses, sarcopenia was negatively associated with higher serum CK levels, but not with serum aspartate aminotransferase or alanine aminotransferase levels independent of pain score and serum CRP. Neither pain score nor serum CRP level was associated with sarcopenia. Similar results were found when the European Working Group on Sarcopenia in Older People criteria were used. CONCLUSIONS Serum CK was associated with sarcopenia, suggesting the potential usefulness for sarcopenia detection regardless of pain or inflammation in OA.

Abstract
AIM To investigate the longitudinal association between health literacy and frailty status at two-year follow-up in community-dwelling older adults. METHODS A total of 218 older adults (mean age, 72.5±4.9 [range 65-86] years old; men, n=81) without frailty at baseline participated in this study. Functional health literacy was assessed using the Newest Vital Sign (NVS). Comprehensive health literacy was assessed using the 47-item European Health Literacy Survey Questionnaire (HLS-EU-Q47). Comprehensive health literacy indices are constructed as a general health literacy index comprising all items along with the three sub-indices of health care, disease prevention, and health promotion domains. Demographic data and other potential confounding factors were also assessed. The total Kihon checklist score was used to monitor the presence of frailty based on a score of ≥8 at the 2-year follow-up (postal survey). RESULTS Of the 253 participants in the follow-up survey, 226 responded (response rate: 89.3%). Excluding the 8 participants with missing values, 25 (11.5%) of the 218 were reported to be frail. A multiple logistic regression analysis indicated that comprehensive health literacy (total score of HLS-EU-Q47) was independently associated with a lower risk of frailty (odds ratio per standard deviation = 0.54, 95% confidence interval = 0.33-0.87) after adjusting for the covariates (age, gender, education, body mass index, gait speed, cognitive function, and comorbidities). The health care and disease prevention domain scores of the HLS-EU-Q47 were also independently associated with a lower risk of frailty. Functional health literacy (NVS score) was not associated with frailty. CONCLUSIONS Older adults with higher comprehensive health literacy are less likely to be frail at two-year follow-up than those with a lower literacy.

Coexistence of low back pain and lumbar kyphosis is associated with increased functional disability in knee osteoarthritis: the Nagahama Study. Arthritis Care Res (Hoboken) 2021; 74:1667-1675. [PMID: 33606899 DOI: 10.1002/acr.24580] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2020] [Revised: 02/04/2021] [Accepted: 02/12/2021] [Indexed: 11/06/2022]
Abstract
OBJECTIVE To examine the association of low back pain (LBP) and lumbar kyphosis with functional disabilities and knee symptoms in patients with knee osteoarthritis (OA). METHODS We analyzed 586 participants (80.1% female; age, 68.8 ± 5.2 years) from the Nagahama Study who were aged ≥60 years and had radiographically confirmed knee OA. The Knee Scoring System (KSS) was used to assess functional disabilities and knee symptoms. LBP was defined as the presence of any persistent back pain for more than 3 months. Lumbar kyphosis was determined by skin-surface methods using a computer-aided electronic device called the Spinal Mouse. Multiple linear regression analysis was used for assessing the association of LBP and lumbar kyphosis with the KSS scores. Subgroup analyses based on sex were also performed. RESULTS LBP and lumbar kyphosis were independently associated with a lower KSS function score after adjustment for covariates (mean difference [95%CI, confidence interval] = -4.96 [-7.56 to -2.36] points for LBP alone, -4.47 [-8.51 to -0.43] points for lumbar kyphosis alone, and -13.86 [-18.86 to -8.86] points for the coexistence of LBP and lumbar kyphosis, respectively). The coexistence of LBP and lumbar kyphosis in women was associated with a lower KSS symptom score (mean difference [95%CI] = -4.49 [-6.42 to -2.55] points). CONCLUSION These findings suggest that both LBP and lumbar kyphosis are useful clinical signals indicating functional disability and knee symptoms in patients with knee OA.

Abstract
INTRODUCTION/OBJECTIVES To test the hypothesis that greater extracellular-to-intracellular water (ECW/ICW) ratios in lower-limb muscles are associated with worsened functional abilities in patients with knee osteoarthritis (OA). METHODS We analyzed data from 787 participants (82.2% female; mean age, 69.6 ± 5.3 years) from the Nagahama Prospective Cohort who were ≥60 years old and had radiographically confirmed bilateral knee OA. The Knee Scoring System (KSS) was used to assess functional abilities. Lower-limb ECW/ICW ratios and skeletal mass index values were determined with multi-frequency bioelectrical impedance analysis (BIA). Multiple linear regression analysis was used to test for associations between ECW/ICW ratios and functional abilities. Subgroup analyses based on OA severities and symptomaticity were also conducted. RESULTS Increased ECW/ICW ratios were associated with a 4.38-point decrease in the KSS function scores (95% confidence interval [CI], 3.15-5.62 points) after adjusting for covariates. This association varied according to the degree of knee symptoms, especially in individuals with radiologically mild OA. ECW/ICW ratios in individuals with asymptomatic mild OA were associated with a 2.14-point decrease in the KSS function score (95% CI, 0.32-3.96 points), whereas those in individuals with severe symptomatic mild OA were associated with a 6.16-point decrease (95% CI, 2.13-10.19 points). CONCLUSIONS Our findings indicate that higher ECW/ICW ratios are associated with greater functional disability in patients with knee OA. Therefore, ECW/ICW ratio measurements with multi-frequency BIA can serve as valuable indicators for functional disability in patients with knee OA. Key Points • Higher extracellular-to-intracellular water (ECW/ICW) ratios are associated with greater functional disability levels in patients with knee osteoarthritis (OA). • ECW/ICW ratios are useful clinical signs as a biomarker for poor functional abilities in patients with knee OA.

Objectives To investigate the longitudinal association of urgency urinary incontinence (UUI) with loss of independence (LOI) or death among independent community-dwelling older adults. Design Population-based cohort study. Setting The Locomotive Syndrome and Health Outcome in Aizu Cohort Study (LOHAS), Minami-Aizu Town and Tadami Town, Fukushima, Japan. Participants A total of 1,580 participants aged ≥65 years who underwent a health check-up conducted by LOHAS in 2010. Measurements Exposure was defined as the presence of UUI, which was measured by a questionnaire based on the definition of UUI from the International Continence Society. The primary outcome was defined as incidence of LOI or death. After the check-up in 2010, the outcome was monitored until March 2014. A multivariable Cox proportional hazard analysis was performed to estimate the hazard ratio for the outcome. Ten potential confounders were adjusted in the analysis. Furthermore, we defined the secondary outcomes as two separate outcomes, LOI and death, and performed the same analysis. Results Among all participants, 328 reported UUI. The incidence rates of the outcome were 20.4 and 11.4 (per 1,000 person–years) among participants with and without UUI, respectively. After multivariable adjustment, those who experienced UUI showed a substantial association with LOI or death (HR, 1.65; 95% CI, 1.01–2.68). However, they did not show such an association with LOI alone (HR, 1.07; 95% CI, 0.49–2.33). On the other hand, those with UUI exhibited a substantial association with death (HR, 2.23; 95% CI, 1.22–4.31). Conclusions In this study, UUI was associated with the occurrence of LOI or death; however, UUI is not associated with the occurrence of LOI alone among independent community-dwelling older adults. Our results suggest that there may be a difference between UUI-associated diseases that cause LOI and those that cause death.

Abstract
Objectives: The Short Form 12 Survey (SF-12) three-component model is used to compute health-related quality of life (QoL): it includes physical, mental, and role-social QoL. We asked whether the SF-12 three-component model is associated with disability-free survival. Methods: People ≥65 years old were included (n = 2634). SF-12 scores were assessed at baseline. The outcome was a composite of loss of independence (LoI) and death. LoI was defined using Japan's long-term care insurance categories. Hazard ratios (HRs) for LoI or death were estimated using Cox proportional hazards models. Results: Better physical QoL was inversely associated with LoI or death (adjusted HR per 10-point increase: .88 [95% CI: .81-.96]), but mental QoL was not. Better role-social QoL was inversely associated with LoI or death only among participants with higher than average physical QoL (adjusted HR per 10-point increase: .79 [95% CI: .65-.96], p for interaction = .04). Discussion: Physical QoL was associated with disability-free survival, and role-social QoL was associated with disability-free survival among those with better physical QoL.

Physical frailty predicts the development of social frailty: a prospective cohort study. BMC Geriatr 2020; 20:403. [PMID: 33054731 PMCID: PMC7557012 DOI: 10.1186/s12877-020-01814-2] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2020] [Accepted: 10/05/2020] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND It has not been clarified whether physical frailty symptoms predict social. frailty. The purpose of this study was to elucidate the effect of physical frailty on social frailty, and to determine which domains of physical frailty predict the development of social frailty. METHODS We employed a two-year prospective cohort study. A total of 342 socially robust community-dwelling older adults were recruited. We used a modified social frailty screening index consisting of four social domains including financial difficulties, living alone, social activity, and contact with neighbors. Physical frailty status was also assessed at baseline. At the two-year follow-up, we assessed the development of social frailty. Social status was assessed using four social subdomains for the primary analysis. Social status was assessed using the two social subdomains of social activity and contact with neighbors, which would be affected by the physical frailty component, for the secondary analysis. The risk ratios (RR) of physical frailty for the development of social frailty were estimated. RESULTS Although physical frailty symptoms were not a significant risk factor for future development of social frailty as assessed by four social subdomains (adjusted RR 1.39, 95% CI 0.95-2.15), it became significant when development of social frailty was assessed by the two social subdomains (adjusted RR 1.78, 95% CI 1.10-2.88). An analysis using the physical frailty subdomain showed that slow gait speed (adjusted RR 3.41, 95% CI 1.10-10.53) and weakness (adjusted RR 1.06, 95% CI 1.01-1.12) were independent risk factors for development of social frailty as assessed by two social subdomains. CONCLUSIONS Physical frailty symptoms predict the development of social frailty. Among physical frailty subdomains, gait speed and muscle strength are critical independent risk factors for future decline in the social aspect. The prevention of physical frailty, especially by maintaining gait ability and muscle strength, may be effective for avoiding social frailty.

Longitudinal association between mental health and future antibiotic prescriptions in healthy adults: Results from the LOHAS. PLoS One 2020; 15:e0240236. [PMID: 33017453 PMCID: PMC7535024 DOI: 10.1371/journal.pone.0240236] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2020] [Accepted: 09/22/2020] [Indexed: 11/19/2022] Open
Abstract
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.

The associations of phase angle with the structural severity and quadriceps strength among patients with hip osteoarthritis: the SPSS-OK study. Clin Rheumatol 2020; 40:1539-1546. [PMID: 32996070 DOI: 10.1007/s10067-020-05419-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2020] [Revised: 09/08/2020] [Accepted: 09/17/2020] [Indexed: 01/10/2023]
Abstract
INTRODUCTION/OBJECTIVES This study examined whether phase angle (PhA) is associated with hip osteoarthritis (HOA) severity and quadriceps strength in patients with HOA. METHOD A series of 549 patients with HOA, obtained from the Screening for People Suffering Sarcopenia in the Orthopedic cohort of Kobe study, were analyzed. PhA and quadriceps strength were measured using bioelectrical impedance analysis and a handheld dynamometer, respectively. The HOA severity was graded using the Kellgren-Lawrence radiographic scale. We estimated (1) mean differences in PhA by differences in HOA severity and (2) mean differences in quadriceps strength by differences in PhA using general linear models. RESULTS The patients' mean age was 64.9 years, and 85% were women. A decreasing trend of PhA associated with increasing HOA severity was observed (P for trend < 0.001). PhA was statistically associated with a decrease in HOA grade 4 compared with that associated with HOA grade 1 (mean difference, - 0.40°; 95% confidence interval (CI), - 0.51° to - 0.30°). PhA per leg was associated with greater quadriceps strength per leg independent of age, sex, leg muscle mass, and HOA severity (mean difference per 1° increase, 3.80 Nm; 95% CI, 0.93 to 6.66). There was insufficient evidence of any difference in the association between PhA and quadriceps strength by HOA severity and sex (P for interaction = 0.07 and 0.06, respectively). CONCLUSIONS PhA gradually decreased with increasing HOA severity, especially in patients with end-stage HOA. Paying close attention to PhA might provide a key to increasing quadriceps strength, regardless of HOA severity. Key Points • PhA gradually decreased with progression of HOA, particularly in patients with end-stage HOA. • PhA was positively associated with quadriceps strength, regardless of HOA severity. • PhA could be one of the indicators of quadriceps strength in patients with HOA.

Abstract
OBJECTIVES Sustaining benefits of an exercise program is difficult as adherence is often poor after supervised intervention is over. This study aimed to determine whether the effects of active learning education on physical activity, dietary habits, and physical function were maintained 24 weeks after intervention termination in older adults. DESIGN Non-randomized controlled trial. SETTING AND PARTICIPANTS Community-dwelling older adults aged ≥65 years who were independent in activities of daily living. METHODS The intervention group (n = 36) underwent 24 weeks of active learning education. The control group (n = 59) attended a health education class didactically. In both groups, the education program focused on exercise, diet and nutrition, and cognitive activity for health promotion. Active learning included exploratory learning, group work, and self-planning for behavior change that promoted healthy lifestyles. Outcome measures were obtained at baseline (pre), 24 weeks (post), and 48 weeks (follow-up). Physical activity was objectively measured as physical activity level (PAL) using a triaxial accelerometer. Food intake was assessed by obtaining a dietary variety score. Physical function, including gait speed and Timed Up & Go score, was tested as secondary outcome. We used a linear mixed model to estimate the effects of intervention in intention-to-treat analyses. RESULTS All outcomes in the intervention group significantly improved compared with the control group at 24 weeks, and the improvements were sustained over a 48-week follow-up period. For PAL, between-group difference in change from baseline was 0.043 (95% confidence interval = 0.007, 0.080) at 24 weeks and 0.061 (0.023, 0.099) at 48 weeks. CONCLUSIONS AND IMPLICATIONS Active learning education is effective in enhancing healthy lifestyles and physical function sustainability beyond intervention cessation. A randomized controlled trial with a larger sample size is needed to conclusively clarify the beneficial effects of active health education learning on sustainable behavior change and functional improvement.

Longitudinal association of fatty pancreas with the incidence of type-2 diabetes in lean individuals: a 6-year computed tomography-based cohort study. J Gastroenterol 2020; 55:712-721. [PMID: 32246380 DOI: 10.1007/s00535-020-01683-x] [Citation(s) in RCA: 28] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/30/2020] [Accepted: 03/19/2020] [Indexed: 02/06/2023]
Abstract
BACKGROUND Only a few studies have longitudinally evaluated whether fatty pancreas increases the risk of type-2 diabetes (T2D), and their results were inconsistent. Fatty pancreas is closely linked to overweight and obesity, but previous studies did not exclude overweight or obese individuals. Therefore, in this cohort study, we investigated the association between fatty pancreas and T2D incidence in lean individuals. METHODS Between 2008 and 2013, 1478 nondiabetic lean individuals (i.e. body-mass index < 25 kg/m2) underwent health examinations including computed tomography (CT) and were followed for a median of 6.19 years. Fatty pancreas was evaluated by a histologically-validated method using pancreas attenuation (Hounsfield units [HU]) on CT at baseline; lower pancreas attenuation indicates more pancreatic fat. To detect incident T2D, we used fasting plasma glucose, HbA1c, and self-reports of prescribed anti-diabetes medications. Odds ratios (OR) for the association between pancreas attenuation and incident T2D were estimated using logistic regression models adjusted for likely confounders. RESULTS T2D occurred in 61 participants (4.13%) during the follow-up period. Lower pancreas attenuation (i.e. more pancreatic fat) at baseline was associated with incident T2D (unadjusted OR per 10 HU lower attenuation: 1.56 [95% CI 1.28-1.91], p < 0.001). The multivariable-adjusted analysis revealed a similar association (adjusted OR per 10 HU lower attenuation: 1.32 [95% CI 1.06-1.63], p = 0.012). CONCLUSIONS T2D was likely to develop in lean individuals with the fatty pancreas. Among people who are neither obese nor overweight, the fatty pancreas can be used to define a group at high risk for T2D.

Abstract
OBJECTIVE In patients with kidney transplant (KT), frailty is a predictor of adverse outcomes. Outcomes of exercise therapy in patients with KT, particularly the efficacy of early exercise after KT, have not been evaluated. We investigated the effect of exercise intervention beginning early after KT on physical performance, physical activity, quality of life, and kidney function in patients with KT. METHODS KT recipients who underwent surgery with usual care plus exercise training from a prospective cohort (exercise group; n = 10) and those with usual care alone from a historical cohort (control group; n = 14) were included in this study. Early exercise comprised supervised aerobic training and physical activity instruction from day 6 to 2 months after KT. The following outcomes were measured: 6-minute walking distance, isometric knee extensor strength, gait speed, physical activity, quality of life, and estimated glomerular filtration rate. RESULTS Analyses of covariance, adjusted for baseline values, revealed significant mean differences between exercise and control groups at 2 months after KT in 6-minute walking distance (+44.4 m, P = .03) and isometric knee extensor strength (+8.1%body weight, P = .03). No significant between-group differences were found in gait speed, physical activity, and quality of life. The analysis of variance for comparison of the area under the recovery curves of estimated glomerular filtration rate after KT revealed no significant difference between groups. CONCLUSION Supervised aerobic training and physical activity instruction initiated in the early phase after KT can improve physical performance without adversely affecting kidney function.

Abstract
Background The impact of length of hospital stay on activities of daily living (ADLs) has not specifically been investigated among dialysis patients. Therefore, we attempt to verify the association between the length of hospital stay and the decline in ADLs among hemodialysis patients. Methods This prospective cohort study used data from the Japanese Dialysis Outcomes and Practice Patterns Study (J-DOPPS). We included 2442 hemodialysis patients aged ≥40 years from the J-DOPPS phase V (2012–2015) and subsequently excluded those who had already lost basic activities of daily living (BADLs) as demonstrated by dependency in at least three of the five BADLs at baseline and for whom changes in ADLs had been evaluated for less than 90 days. The main exposure was the cumulative length of hospital stay during the follow-up period. The primary outcomes were a decline in at least one of the five BADLs and eight instrumental activities of daily living (IADLs). We compared risk ratios (RRs) for 30-day increments for hospital stays with 10-year increments for age and having diabetes. Results A total of 849 patients were included in the statistical analysis. The cumulative length of hospital stay was significantly associated with a risk of decline in ADLs (adjusted RRs [95% confidence intervals] per 30-day increments: 1.42 [1.15 to 1.75] for BADLs, 1.38 [1.13 to 1.68] for IADLs). The adjusted RRs [95% CI] for 10-year increments in age were 1.20 [0.96 to 1.50] and 1.21 [1.00 to 1.47]. The adjusted RRs [95% CI] for having diabetes were 1.36 [0.97 to 1.91] for BADLs and 1.38 [1.04 to 1.84] for IADLs. Conclusion The impact of a 30-day increment in the cumulative length of hospital stay on the decline in ADLs was comparable to that of a 10-year increase in age and having diabetes.

Abstract
Life-space mobility describes the spatial areas through which an individual moves, and the frequency and need for assistance. Although patients with knee osteoarthritis (OA) have shown restricted life-space mobility, total knee arthroplasty (TKA) does not improve it beyond preoperative levels. Life-space mobility after TKA was influenced by self-efficacy for walking tasks; thus, an intervention to improve self-efficacy for walking tasks may contribute to better life-space mobility. We provided a walking event including several walking tasks as the intervention. We assessed the effect of the walking event on life-space mobility and self-efficacy for walking tasks in patients following TKA. In this nonrandomized controlled trial, patients who underwent primary TKA were recruited. After recruitment, patients who could not participate in the walking event due to scheduling conflicts were included in the control group. The walking event consisted of 3.5 km of walking course and included walking tasks as follows: crossing at the crosswalk, walking up- and downstairs without a railing, walking along dirt roads, and walking up and down a slope. The primary outcome was life-space mobility measured using Life-Space Assessment (LSA) and self-efficacy for walking tasks measured using the modified Gait Efficacy Scale (mGES). We enrolled 104 patients, of whom 36 were assigned to the intervention group and participated in the walking event. Participants in the intervention group had significantly better LSA score (adjusted mean difference between groups: 13.9; 95% confidence interval: 12.4-15.5; p < 0.001) and mGES score (adjusted mean difference between groups: 13.8; 95% confidence interval: 12.4-15.1; p < 0.001) than the control group even after adjusting for age, gender, body mass index, elapsed time from surgery, the severity of knee OA of nonoperated limb, and patient-reported functional outcome. The walking event including various walking tasks improved life-space mobility and self-efficacy in patients following TKA. It is important to design a program that can improve self-efficacy for walking tasks through mastery experiences to improve life-space mobility after TKA.

Association of low alanine aminotransferase with loss of independence or death: A 5-year population-based cohort study. J Gastroenterol Hepatol 2019; 34:1793-1799. [PMID: 30761612 DOI: 10.1111/jgh.14631] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/04/2019] [Revised: 02/02/2019] [Accepted: 02/11/2019] [Indexed: 12/23/2022]
Abstract
BACKGROUND AND AIM Alanine aminotransferase (ALT) is an important enzyme for amino acid metabolism and gluconeogenesis, and low ALT is an indicator of vitamin B6 deficiency. However, it is unknown whether individuals with low ALT are likely to develop loss of independence (LOI) or death. We investigated the association of low ALT with LOI or death in the elderly. METHODS Between 2008 and 2010, 2,484 elderly individuals (≥ 65 years old) without functional dependency from the Locomotive Syndrome and Health Outcomes in the Aizu Cohort Study were enrolled. Based on baseline ALT values, the participants were divided into the following groups: ALT < 10 (n = 73), 10-20 (n = 1,372), 20-30 (reference, n = 734), 30-40 (n = 201), and ≥ 40 (n = 104) U/L groups. LOI was defined as requiring complete support for basic activities of daily living, which is care levels 3-5 in Japanese long-term care insurance certifications. The hazard ratios of LOI or death were estimated by Cox proportional hazard models adjusted for potential confounders. RESULTS During the median follow-up period of 5.75 (interquartile range 4.85-5.83) years, LOI or death occurred in 195 participants (7.85%). Compared with ALT 20-30 U/L, low ALT was associated with LOI or death (multivariable adjusted hazard ratios [95% confidence intervals]: 3.02 [1.57-5.81] and 1.55 [1.07-2.24] in ALT < 10 and 10-20 U/L groups, respectively), while high ALT was not (1.29 [0.72-2.31] and 1.49 [0.68-3.25] in ALT 30-40 and ≥ 40 U/L groups, respectively). CONCLUSIONS Clinicians should be aware of not only high ALT, indicating liver injury, but also low ALT associated with LOI or death.

Abstract
BACKGROUND Patients who undergo total knee arthroplasty (TKA) may experience disease-specific problems, including decline in motor function and intense pain, which may result in disease-specific anxiety. This study aimed to investigate disease-specific anxiety at discharge, and any association between anxiety and functional outcomes following TKA. METHODS The study prospectively included 129 patients who had undergone TKA. Each patient's disease-specific anxiety about wounds, pain, gait, and falling was assessed at discharge using a numerical rating scale, in which 0 represented no anxiety and 10 represented the highest level of anxiety. In addition, patient-reported outcomes (PROs) were evaluated using the Knee Society Score (KSS) at six-months postoperatively. The effects of disease-specific anxiety at discharge were evaluated with the KSS at six-months postoperatively and analyzed separately using multiple regression analysis. RESULTS The median score for anxiety about wounds, pain, and gait was 4.0 (IQR 2.0-5.0) at discharge five days after surgery. The median score for anxiety about falling was also 4.0 (IQR 2.0-6.0). The level of anxiety regarding wounds, pain, gait, and falling was negatively associated with the KSS six-months postoperatively after adjusting for all confounding factors (wounds: β = -2.8, 95% CI -4.3 to -1.3; pain: β = -3.4, 95% CI -4.9 to -1.9; gait: β = -4.3, 95% CI -5.8 to -2.9; falling: β = -2.5, 95% CI -3.9 to -1.1). CONCLUSION Patients reported similar levels of anxiety regarding wounds, pain, gait, and falling at discharge after TKA. The severity of anxiety symptoms at discharge was negatively associated with PROs six-months postoperatively.

OBJECTIVES To validate the SARC-F questionnaire for sarcopenia screening in musculoskeletal disease setting, and to assess improvements in diagnostic accuracy by adding "EBM" (elderly and body mass index information) to the SARC-F. DESIGN Diagnostic accuracy study. SETTING AND PARTICIPANTS The center involved in this study was located in an urban area of Kobe City, Japan. People with musculoskeletal disease in the knee, hip, or spine who were scheduled for surgical treatment were included. MEASUREMENTS Sarcopenia was evaluated using the Asian Working Group for Sarcopenia (AWGS) and the European Working Group on Sarcopenia in Older People (EWGSOP2), which included bioimpedance, handgrip strength, and gait speed. Patients answered the SARC-F questionnaire and their body mass index was measured. SARC-F and "EBM" information were combined into an original score. The sensitivities, specificities, and areas under the receiver operating characteristic curve (AUC) were estimated and compared to identify sarcopenia. RESULTS A total of 959 patients were included. Sarcopenia by AWGS criteria was identified in 36 (3.8%) patients. SARC-F had a sensitivity of 41.7% and specificity of 68.5%. SARC-F+EBM had a sensitivity of 77.8% and specificity of 69.6%, with substantial improvement in sensitivity (P<0.001). The AUCs for SARC-F and SARC-F+EBM were 0.557 (95% confidence interval [CI] 0.452-0.662) and 0.824 (95% CI 0.762-0.886), respectively (P<0.001). Similar results were obtained when EWGSOP2 criteria were used as the reference standard. CONCLUSION The SARC-F alone is not adequate for finding cases in musculoskeletal disease settings. SARC-F+EBM significantly improved the sensitivity and overall diagnostic accuracy of the SARC-F for screening sarcopenia. SARC-F+EBM is potentially useful for screening sarcopenia in different ethnic and disease settings.

Decline in the Functional Status and Mortality in Patients on Hemodialysis: Results from the Japan Dialysis Outcome and Practice Patterns Study. J Ren Nutr 2018; 29:504-510. [PMID: 30591357 DOI: 10.1053/j.jrn.2018.10.012] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2018] [Revised: 10/10/2018] [Accepted: 10/26/2018] [Indexed: 11/11/2022] Open
Abstract
OBJECTIVES Patients with end-stage renal disease (ESRD) treated with hemodialysis suffer a high burden of poor functional status. Poor functional status is known as a strong, consistent predictor of mortality. However, little is known about the trajectory of functional status and its association with clinical outcomes in the ESRD population. We examined the association between a change in the functional status over time and all-cause mortality among patients on hemodialysis. DESIGN AND METHODS This was a prospective cohort study of 817 patients with ESRD on hemodialysis with repeat measures of functional status, who enrolled in the Japan Dialysis Outcomes and Practice Patterns Study phase V. The functional status was assessed based on the Katz Index and Lawton-Brody instrumental activities of daily living scale, and the assessments were conducted twice over a median of 361 (range: 339-378) days between 2012 and 2013. We classified patients into 2 groups based on having or not having at least a 1-point decline in the functional status score. To evaluate the association between the decline in the functional status and all-cause mortality with adjustment for potential confounders, a Cox regression analysis was conducted. RESULTS Over the study period, 19.9% of the patients showed a decline in the functional status score. During the follow-up period, 44 (5.4%) patients died. Using the Cox regression analysis and adjusting for potential confounders, it was determined that the decline in functional status score was significantly associated with higher mortality (incidence rate: 2.2 vs. 7.0 per 100 person-years; adjusted hazard ratio: 2.68; 95% confidence interval: 1.31-5.50). CONCLUSIONS The present study provides evidence that ESRD patients on hemodialysis demonstrating a decline in the functional status are at elevated risk of mortality. Our findings strengthen the evidence underpinning the importance of interventions to maintain the functional status in this vulnerable population.

Association Between the Discrepancy in Self-Reported and Performance-Based Physical Functioning Levels and Risk of Future Falls Among Community-Dwelling Older Adults: The Locomotive Syndrome and Health Outcomes in Aizu Cohort Study (LOHAS). J Am Med Dir Assoc 2018; 20:195-200.e1. [PMID: 30409491 DOI: 10.1016/j.jamda.2018.09.009] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2018] [Revised: 08/17/2018] [Accepted: 09/10/2018] [Indexed: 11/16/2022]
Abstract
OBJECTIVES A discrepancy in self-reported and performance-based physical functioning levels is often observed among older adults. We investigated the association of discrepancy in self-reported and performance-based physical functioning levels with risk of future falls among community-dwelling older adults. DESIGN Prospective cohort study. SETTING Two communities in Fukushima Prefecture, Japan. PARTICIPANTS 1379 older adults who took part in the yearly health checkup in both 2009 and 2010. MEASURES The performance-based and self-reported physical functioning levels were evaluated by the Timed Up and Go test and the Short-Form 12 Health Survey (Japanese version) physical functioning subscale, respectively. We divided the participants into 4 groups based on the combinations of low or high performance-based and self-reported physical functioning groups, which were classified by age- and sex-specific reference values. The main outcome was the occurrence of any falls within the 1-year follow-up period, assessed using a self-reported questionnaire. RESULTS A total of 22% of the participants reported the occurrence of a fall during the follow-up period. In multivariable logistic regression analysis, the adjusted odds ratios of the high self-reported and low performance-based, low self-reported and high performance-based, and low self-reported and low performance-based physical functioning groups were 1.10 (95% confidence interval [CI], 0.67-1.82), 1.76 (95% CI, 1.17-2.66), and 1.80 (95% CI, 1.11-2.90), respectively, compared with the high self-reported and high performance-based physical functioning group. CONCLUSIONS Our findings suggest that the discrepancy as high performance-based but low self-reported physical functioning level is associated with an increased risk of future falls in older adults aged 65-89 years. Clinicians should carefully assess older adults whose subjective perception of their physical functioning capacity is lower than those in similar age and sex groups, even if their actual physical functioning appears to be objectively high.

Influence of the severity of knee osteoarthritis on the association between leg muscle mass and quadriceps strength: the SPSS-OK study. Clin Rheumatol 2018; 38:719-725. [PMID: 30341702 DOI: 10.1007/s10067-018-4337-2] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2018] [Revised: 10/02/2018] [Accepted: 10/11/2018] [Indexed: 10/28/2022]
Abstract
Quadriceps strength is important for maintaining functional movement in patients with knee osteoarthritis (OA). We aimed to examine whether knee OA severity weakened the magnitude of the associations between leg muscle mass, quadriceps strength, and functional movement. Screening for People Suffering Sarcopenia in Orthopedic cohort of Kobe study (SPSS-OK) was a single-center cross-sectional study. We recruited 611 patients with knee OA. Leg muscle mass was determined by bioimpedance and used as a proxy for quadriceps muscle mass. Quadriceps strength and indices of functional movement (assessed by the functional activities category of the new Knee Society Score questionnaire [KSS] and the Timed Up and Go [TUG] test) were measured. Knee OA severity was determined by the Kellgren-Lawrence radiographic grade. A series of general linear models was fitted with adjustment for confounding variables. The increase in quadriceps strength per leg associated with a 1-kg increase in leg mass per leg was 7.29 Nm, 5.43 Nm, and 3.77 Nm among patients with knee OA grade 1/2, 3, and 4, respectively (P for interaction = 0.003). A 1-Nm increase in quadriceps strength per leg was associated with both a 0.14 point increase in KSS movement score and a 0.05 s decrease in TUG, regardless of knee OA severity (P for interaction 0.430 and 0.323). Severe knee OA may reduce efficiency in the exertion of quadriceps strength by leg muscle mass even when the amount of muscle mass remains unchanged.

Development and validation of a prediction model for loss of physical function in elderly hemodialysis patients. Nephrol Dial Transplant 2018; 33:1452-1458. [PMID: 28992129 PMCID: PMC6070092 DOI: 10.1093/ndt/gfx260] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2017] [Accepted: 07/13/2017] [Indexed: 12/13/2022] Open
Abstract
Background Among aging hemodialysis patients, loss of physical function has become a major issue. We developed and validated a model of predicting loss of physical function among elderly hemodialysis patients. Methods We conducted a cohort study involving maintenance hemodialysis patients ≥65 years of age from the Dialysis Outcomes and Practice Pattern Study in Japan. The derivation cohort included 593 early phase (1996-2004) patients and the temporal validation cohort included 447 late-phase (2005-12) patients. The main outcome was the incidence of loss of physical function, defined as the 12-item Short Form Health Survey physical function score decreasing to 0 within a year. Using backward stepwise logistic regression by Akaike's Information Criteria, six predictors (age, gender, dementia, mental health, moderate activity and ascending stairs) were selected for the final model. Points were assigned based on the regression coefficients and the total score was calculated by summing the points for each predictor. Results In total, 65 (11.0%) and 53 (11.9%) hemodialysis patients lost their physical function within 1 year in the derivation and validation cohorts, respectively. This model has good predictive performance quantified by both discrimination and calibration. The proportion of the loss of physical function increased sequentially through low-, middle-, and high-score categories based on the model (2.5%, 11.7% and 22.3% in the validation cohort, respectively). The loss of physical function was strongly associated with 1-year mortality [adjusted odds ratio 2.48 (95% confidence interval 1.26-4.91)]. Conclusions We developed and validated a risk prediction model with good predictive performance for loss of physical function in elderly hemodialysis patients. Our simple prediction model may help physicians and patients make more informed decisions for healthy longevity.

Oxygen Transport Capacity and Hemodynamic Effect of Newly Developed Artificial Blood “Neo Red Cells (NRC)”. Int J Artif Organs 2018.

Abstract
The purpose of this study was to evaluate liposome-encapsulated hemoglobin, named Neo Red Cells (NRC), on hemodynamics and oxygen-transport capacity in a blood exchange experiment. The experiment was carried out in nine mongrel dogs. Depending on the percentage of blood exchange with NRC, the animals were divided into two groups; Group I (4 animals with an exchange rate less than 88%), and Group II (5 animals with an exchange rate over 88%). After blood exchange, total peripheral vascular resistance index (TPRI) decreased and cardiac index (CI) increased. These changes were more marked in Group II than in Group I, thus showing that NRC relieved the burden on the heart, probably due to the fact that the viscosity of NRC is 2 cp which is less than 1/3 that of whole blood. The oxygen binding capacity per 1g hemoglobin in NRC was 2-4 times as much as red blood cells. Thus, NRC was superior to natural red blood cells in terms of oxygen transport capacity and its effects on the circulatory system.
