RESUMEN

OBJECTIVE: To determine whether periodontal status is associated with oral function, including masticatory performance and occlusal force, among community-dwelling older adults. BACKGROUND: Although a potential association between periodontal status and oral function has been reported, variations in the root surface area (RSA) of each tooth have not been considered. METHODS: We used data from a population-based study involving community-dwelling older adults. The RSA with periodontal ligament (RSA-PL), which quantifies the RSA attached to the periodontal ligament and alveolar bone, was calculated based on full-mouth periodontal examination. Masticatory performance was assessed using spectrophotometric measurement of the color (a* value) of color-changing chewing gum. The bilateral maximal occlusal force (MOF) was measured using a pressure-sensitive sheet and dedicated software. The associations of the RSA-PL, a quantitative marker of periodontal tissue support, with the a* value and MOF were assessed using linear regression models. RESULTS: The analyses included data from 250 adults [60.8% women; age, mean (standard deviation) 82.5 (5.0) years]. On average, the study participants had an RSA-PL of 26.3 cm2 , a* value of 25.0, and an MOF value of 555.1 N. After adjustments for potential confounders, including dentition status, age, sex, dental visit regularity, smoking status, physical activity level, depressive symptoms, a history of stroke or diabetes mellitus, and body mass index, the RSA-PL was found to be associated with the a* value [coefficient (per 1 cm2 increase): 0.16, 95% confidence interval (CI) 0.10-0.22)] and MOF (coefficient: 9.2, 95% CI 5.3-13.1). CONCLUSION: This study demonstrated that greater amounts of remaining tooth-supporting structures, indicated by higher RSA-PL values, were associated with better masticatory performance and a higher occlusal force among community-dwelling older adults.

RESUMEN

OBJECTIVE: To investigate the potential association between periodontitis and arterial stiffness among the older Japanese population. BACKGROUND: The prevalence of periodontitis is increasing in Japanese older adults. Arterial stiffness increases the risks of cardiovascular events and death, morbidity, and dementia. METHODS: This secondary analysis of data from a cross-sectional study evaluated the periodontal inflamed surface area (PISA), reflecting the amount of inflamed periodontal tissue that was estimated by a full-mouth periodontal examination. Severe periodontitis was defined per the parameters provided by the Centers for Disease Control/American Academy of Periodontology. The Cardio-Ankle Vascular Index (CAVI) was used for measuring the overall stiffness of the artery, and higher CAVI indicated increased arterial stiffness. An ordinal logistic regression model was used to evaluate the association between periodontitis and arterial stiffness. RESULTS: The analysis included 185 Japanese adults [35% men; age, mean (standard deviation) 80.2 (4.4) years]. The average PISA and the prevalence of severe periodontitis were 64.4 mm2 and 27.6%, respectively; 54 (29.2%), 56 (30.3%), and 75 (40.5%) participants were stratified to the CAVI < 9, 9 ≤ CAVI <10, and CAVI ≥ 10 groups, respectively. After adjusting for potential confounders, the odds ratio of the prevalence and severity of arterial stiffness evaluated using CAVI was 1.06 [95% confidence interval (CI) 1.01 to 1.10] for PISA per 10 mm2 and 2.12 (95% CI 1.09 to 4.11) for severe periodontitis. CONCLUSION: Periodontitis was associated with arterial stiffness among Japanese older adults. Further studies are needed to investigate whether arterial stiffness is an intermediate factor in the pathway between periodontitis and systemic diseases, including cardiovascular disease and dementia.

RESUMEN

OBJECTIVE: This study aimed to investigate the longitudinal association of the combination of poor appetite (PA) and low masticatory function (LMF) with sarcopenia in community-dwelling older adults. METHODS: In total, 173 community-dwelling Japanese adults aged ≥ 75 years participated in the 3-year cohort study. Appetite assessment using the Simplified Nutritional Appetite Questionnaire (SNAQ) and masticatory function assessment using spectrophotometric measurement of differences in gum colour before and after masticating colour-changeable chewing gum (ΔE*ab) were performed at baseline. SNAQ score of ≤ 14 was defined as PA. The lowest tertile of ΔE*ab was defined as LMF. Follow-up examinations were administered annually over a 3-year period to determine sarcopenia incidence, which was defined by the criteria proposed by the Asian Working Group for Sarcopenia. Adjusted hazard ratios (HRs) of sarcopenia incidence according to the presence of PA and LMF were calculated using Cox proportional hazards regression models. RESULTS: At baseline, 81 participants (46.8%) had neither PA nor LMF, 34 (19.7%) had PA alone, 35 (20.2%) had LMF alone, and 23 (13.3%) had both PA and LMF. On follow-up, 31 participants (17.9%) developed sarcopenia. After adjusting for covariates, the adjusted HR for sarcopenia in participants with both PA and LMF was 4.4 (95% confidence interval = 1.6-12.2) compared with those without PA or LMF. PA or LMF alone was not significantly associated with sarcopenia development. CONCLUSIONS: Coexisting PA and LMF increase the risk of sarcopenia development among community-dwelling Japanese adults aged ≥ 75 years.

RESUMEN

BACKGROUND AND OBJECTIVES: Identification of modifiable factors for mild cognitive impairment (MCI) is important since individuals with MCI are at a high risk of dementia and disability. Previous studies have suggested a potential association between periodontitis and cognitive impairment, but the results remain inconclusive. We designed a 5-year longitudinal study to explore the association between MCI and periodontitis and periodontal inflammation in older adults. METHODS: This study included 179 community-dwelling dentate individuals (62 men and 117 women, average age: 80.1 years). A full-mouth periodontal examination at six sites per tooth was performed at baseline. Case definitions provided by the European Workshop in Periodontology Group C (EWP definition) and the Centers for Disease Control/American Academy of Periodontology (CDC/AAP definition) were used to define severe periodontitis. Additionally, the periodontal inflamed surface area (PISA), reflecting the amount of inflamed periodontal tissue, was calculated using clinical periodontal parameters. Follow-up cognitive examinations for MCI diagnosis were performed by neurologists 1, 2, 3, and 5 years after baseline. Odds ratios (ORs) for MCI according to the presence of periodontitis and periodontal inflammation at baseline were calculated using multilevel mixed-effects logistic regression. RESULTS: At baseline, 56.4% and 27.4% of the participants had severe periodontitis by the EWP and CDC/AAP definitions, respectively. After adjusting for follow-up period and other baseline health characteristics (age, sex, smoking status, educational level, physical activity level, obesity, depression, and diabetes), severe periodontitis by either definition was significantly associated with MCI (for the EWP definition: adjusted OR = 3.58, 95% confidence interval [CI] = 1.45-8.87; for the CDC/AAP definition: adjusted OR = 2.61, 95% CI = 1.08-6.28). Periodontal inflammation assessed by PISA was also significantly associated with a higher OR for MCI (adjusted OR = 1.05, 95% CI = 1.01-1.10, per 10-mm2 increase in PISA). CONCLUSION: Severe periodontitis and periodontal inflammation were associated with incident MCI among older community-dwelling men and women.

RESUMEN

Bone metastasis is one of the most intractable bone diseases; it is accompanied with a severe mechanical dysfunction of bone tissue. We recently discovered that the disorganized collagen/apatite microstructure in cancer-bearing bone is a dominant determinant of the disruption of bone mechanical function; disordered osteoblast arrangement was found to be one of the principal determinants of the deteriorated collagen/apatite microstructure. However, the precise molecular mechanisms regulating the disordered osteoblast arrangement triggered by cancer invasion are not yet understood. Herein, we demonstrate a significant disorganization of bone tissue anisotropy in metastasized bone in our novel ex vivo metastasis model. Further, we propose a novel mechanism underlying the disorganization of a metastasized bone matrix: A dynamic collision behavior between tumor cells and osteoblasts disturbs the osteoblast arrangement along the collagen substrate.

RESUMEN

BACKGROUND: Previous studies have reported that self-rated health (SRH) predicts subsequent mortality. However, less is known about the association between SRH and functional ability. The aim of this study was to examine whether SRH predicts decline in basic activities of daily living (ADL), even after adjustment for depression, among community-dwelling older adults in Japan. METHODS: A three-year prospective cohort study was conducted among 654 residents aged 65 years and older without disability in performing basic ADL at baseline. SRH was assessed using a visual analogue scale (range; 0-100), and dichotomized into low and high groups. Information on functional ability, sociodemographic factors, depressive symptoms, and medical conditions were obtained using a self-administered questionnaire. Logistic regression analysis was used to examine the association between baseline SRH and functional decline three years later. RESULTS: One hundred and eight (16.5%) participants reported a decline in basic ADL at the three-year follow-up. Multiple logistic regression analysis showed that the low SRH group had a higher risk for functional decline compared to the high SRH group, even after controlling for potential confounding factors (odds ratio (OR) = 2.4; 95% confidence interval (CI) = 1.3-4.4). Furthermore, a 10-point difference in SRH score was associated with subsequent functional decline (OR = 1.37; 95% CI = 1.16-1.61). CONCLUSIONS: SRH was an independent predictor of functional decline. SRH could be a simple assessment tool for predicting the loss or maintenance of functional ability in community-dwelling older adults. Positive self-evaluation might be useful to maintain an active lifestyle and stay healthy.

RESUMEN

BACKGROUND: Previous studies have found that social cohesion and trust (SCT) were associated with psychological well-being and physical health. In this study, we investigated the associations between SCT and mental and physical health among community-dwelling elderly in a town in southern Taiwan. METHODS: The study population consisted of 149 community-dwelling elderly aged 65 years and older (68 men, 81 women; mean age, 75.4 ± 6.1 years) residing in the town of Dashe in southern Taiwan. Activities of daily living (ADL), SCT, depression, subjective quality of life (QOL), current medical status, past medical history, and health behaviors were assessed in face-to-face interviews. Objective neurobehavioral functions were assessed using the timed up & go (TUG) test, functional reach test, and handgrip test. RESULTS: Scores for ADL and Geriatric Depression Scale (GDS) were significantly correlated with SCT, and SCT was significantly correlated with all subjective QOL items. In addition, a strong correlation was observed between SCT and relationship with friends. Values for SCT (median ≥ 20) were significantly associated with both subjective sense of health (median ≥ 68) and subjective happiness (median ≥ 73) after adjusting for age, sex, and ADL. CONCLUSION: SCT is an important variable that influences self-rated health and happiness, independently of ADL, age, and sex. When assessing geriatric psychological function, SCT should be examined more carefully, given its association with subjective sense of health and happiness, depression, and physical function.

RESUMEN

OBJECTIVE: Several environmental factors including hypoxia have been reported to contribute to oxidative stress in individuals living in the highlands. However, little is known about the role of oxidized low-density lipoprotein (ox-LDL) among community-dwelling elderly in the Qinghai-Tibet plateau. METHODS: The study population comprised 168 community-dwelling elderly subjects aged 60 years or older (male to female ratio, 70:98; mean age, 65.8 years) living in Haiyan County, located 3000 to 3200 m above sea level, 30 km northwest of Xining, Qinghai. The subjects were volunteers who joined a Comprehensive Geriatric Assessment. Plasma ox-LDL was measured in 168 community-dwelling elderly subjects aged 60 years or older (23 Tibetans and 145 Hans) with a monoclonal antibody-based enzyme-linked immunosorbent assay. RESULTS: Mean ox-LDL level was higher among Tibetan elderly than Han elderly (Tibetan, 79.0 ± 29.6 U/L; Han, 62.8 ± 23.5 U/L; P = .003). Tibetan ethnicity was significantly associated with ox-LDL levels after adjusting for LDL cholesterol levels. In addition, high ox-LDL levels (≥70 U/L) were significantly associated with a homeostasis model assessment insulin resistance index of at least 1.6 (odds ratio [OR], 2.82; 95% confidence interval [95% CI], 1.11 to 7.15; P = .029) and ankle brachial pressure index of less than 1.0 (OR, 4.85; 95% CI, 1.14 to 10.00; P = .028), after adjusting for age, sex, and ethnicity. CONCLUSIONS: Our findings support the hypothesis that ox-LDL levels are higher among Tibetan elderly highlanders compared with those among Han elderly. As ox-LDL levels can affect insulin resistance and arteriosclerosis, further research is needed to determine how oxidative stress influences the health situation among elderly individuals at high altitudes.

RESUMEN

Recently, it was reported that concomitant hemodialysis (HD) in peritoneal dialysis (PD) patients facilitated continuation of PD treatment and mitigated the deterioration of peritoneal function in patients with uremic symptoms and excess body fluid associated with loss of residual renal function. To determine the effect of combined HD and PD on patient and technique survival, we undertook a retrospective cohort study of patients who underwent PD at Saitama Medical University Hospital between 1995 and 2010. We compared patients who started PD during 1995 2002 with those who started during 2003- 2010. Because our center started a new strategy of supplementing PD with once-weekly HD in 2000, the effects of combination therapy could be determined by comparing the data obtained during the two periods. The 440 patients (274 men, 166 women) who started PD during the study period had a mean age of 60.2 +/- 73 years. The mean age was significantly higher in the 2003 - 2010 group than in the 1995 - 2002 group. Using a Kaplan-Meier plot, we observed a significant difference in technique survival (p < 0.001). The technique survival rate at 3 and 5 years was, respectively, 89% and 74% in the 2003-2010 group and 68% and 35% in the 1995 - 2002 group (p < 0.05). Cumulative patient survival at 3 and 5 years was, respectively, 87% and 72% in the 2003 - 2010 group and 69% and 51% in the 1995 - 2003 group (p < 0.01). Patient and technique survival were significantly improved in PD patients receiving the combination of HD and PD.

RESUMEN

BACKGROUND: Missing data are inevitable in almost all medical studies. Imputation methods using the probabilistic model are common, but they cannot impute individual data and require special software. In contrast, the ipsative imputation method, which substitutes the missing items by the mean of the remaining items within the individual, is easy and does not need any special software, but it can provide individual scores. The aim of the present study was to evaluate the validity of the ipsative imputation method using data involving the 15-item Geriatric Depression Scale. METHODS: Participants were community-dwelling elderly individuals (n = 1178). A structural equation model was constructed. The model fit indexes were calculated to assess the validity of the imputation method when it is used for individuals who were missing 20% of data or less and 40% of data or less, depending on whether we assumed that their correlation coefficients were the same as the dataset with no missing items. Finally, we compared path coefficients of the dataset imputed by ipsative imputation with those by multiple imputation. RESULTS: When compared with the assumption that the datasets differed, all of the model fit indexes were better under the assumption that the dataset without missing data is the same as that that was missing 20% of data or less. However, by the same assumption, the model fit indexes were worse in the dataset that was missing 40% of data or less. The path coefficients of the dataset imputed by ipsative imputation and by multiple imputation were compatible with each other if the proportion of missing items was 20% or less. CONCLUSION: Ipsative imputation appears to be a valid imputation method and can be used to impute data in studies using the 15-item Geriatric Depression Scale, if the percentage of its missing items is 20% or less.

RESUMEN

AIM: This study examined the associations between geriatric factors and decreased opportunities for conversation among older adults amid a period of self-restraint during the COVID-19 pandemic. METHODS: A cross-sectional questionnaire-based survey was carried out in October 2020. The participants were 204 residents aged ≥65 years staying at a private care home in Kyoto city, Japan. Logistic regression analysis was carried out with the reduction of conversation opportunities as the dependent variable, and geriatric factors as independent variables after adjusting for age and sex. We compared the decreased frequency of opportunities between residents in the assisted living wing and in the nursing care wing of the private care home. RESULTS: The percentages of respondents who reported a decrease in the opportunities for conversation among themselves were 43.9% for residents in the assisted living wing and 19.7% for those in the nursing care wing. After adjusting for age and sex, the opportunities for conversation was significantly associated with the basic activities of daily living (OR 1.07, 95% CI 1.01-1.12), instrumental self-maintenance (OR 1.25, 95% CI 1.08-1.46), intellectual activity (OR 1.35, 95% CI 1.09-1.66), depression (OR 1.13, 95% CI 1.04-1.23), depressive mood (OR 3.83, 95% CI 1.98-7.42), decreased motivation (OR 3.11, 95% CI 1.58-6.12), appetite loss (OR 4.32, 95% CI 1.54-12.07), swallowing function (OR 1.05, 95% CI 1.00-1.10), chewing difficulty (OR 2.50, 95% CI 1.31-4.75) and eating alone (OR 2.5, 95% CI 1.35-4.62). CONCLUSION: Decreased opportunities for conversation was more perceived among older adults with higher daily functioning, suggesting that it is associated with depressed mood, oral function and solitary eating.

RESUMEN

Decay-in-storage for radioactive waste including that of nuclear medicine has not been implemented in Japan. Therefore, all medical radioactive waste is collected and stored at the Japan Radioisotope Association Takizawa laboratory, even if the radioactivity has already decayed out. To clarify the current situation between Takizawa village and Takizawa laboratory, we investigated the radiation management status and risk communication activities at the laboratory via a questionnaire and site visiting survey in June 2010. Takizawa laboratory continues to maintain an interactive relationship with local residents. As a result, Takizawa village permitted the acceptance of new medical radioactive waste containing Sr-89 and Y-90. However, the village did not accept any non-medical radioactive waste such as waste from research laboratories. To implement decay-in-storage in Japan, it is important to obtain agreement with all stakeholders. We must continue to exert sincere efforts to acquire the trust of all stakeholders.

RESUMEN

In order to promote consensus building on decommissioning operation rules for medical linear accelerators in Japan, we carried out a risk communication (RC) approach mainly providing knowledge for maintenance staff regarding induced radioactivity. In February 2012, we created a booklet (26 pages) to present an overview of the amended law, the mechanism and the distribution of induced radioactivity showing the actual radiation dose rate around a linear accelerator and actual exposure doses to staff. In addition, we co-sponsored a seminar for workers in this field organized by the Japan Medical Imaging and Radiological Systems Industries Association to explain the contents of this booklet, and answer questions regarding induced radioactivity of linear accelerators as an RC program. As a result, the understanding of staff regarding the regulations on maximum X-ray energy on linear accelerators (P<0.05), and the outline of clearance systems (P<0.01), were facilitated by RC. In addition, we found that about 70% of maintenance staff considered that the cooling time for decommissioning operation depended on the situation. Our RC approach suggests that consensus building should be used to make rules on decommissioning operations for linear medical accelerators.

RESUMEN

AIM: Although the relationship between impaired glucose tolerance (IGT) and mortality has been investigated in diverse populations, few studies have focused on older populations. This study aimed to investigate the relationship between glucose tolerance and overall mortality among populations aged ≥75 years. METHODS: Data were obtained from the Tosa Longitudinal Aging Study, a community-based cohort survey conducted in Kochi, Japan. According to the results of a 75-g oral glucose tolerance test conducted in 2006, the participants were classified into four categories: normal glucose tolerance (NGT), impaired fasting glucose (IFG)/IGT, newly diagnosed diabetes mellitus (NDM), and known diabetes mellitus (KDM). The primary endpoint was overall mortality. Differences in overall mortality among the four categories were evaluated using the Cox proportional hazards model. RESULTS: During a median of 11.5 years of observation, 125 deaths of the 260 enrolled participants were recorded. The cumulative overall survival rate was 0.52, and the survival rates of NGT, IFG/IGT, NDM, and KDM were 0.48, 0.49, 0.49, and 0.25, respectively (log-rank test, P = 0.139). Adjusted hazard ratios (HRs) for mortality in the IFG/IGT and NDM groups compared with the NGT group were 1.02 (95% confidence interval [CI], 0.66-1.58) and 1.11 (95% CI, 0.56-2.22), while mortality in the KDM group was significantly higher than that in the NGT group (HR, 2.43; 95% CI, 1.35-4.37). CONCLUSION: Mortality did not differ significantly between the IFG/IGT, NDM, and NGT groups, but was higher in the KDM group than in the NGT group. Geriatr Gerontol Int 2023; 23: 341-347.

RESUMEN

Peritonitis remains a leading complication of peritoneal dialysis (PD). The aim of this observational retrospective cohort study, conducted at our single center, was to determine the risk factors for peritonitis. A Cox proportional hazards model was used for the multivariate analysis. The event investigated was peritonitis, and the variables studied were sex, age, diabetes mellitus, use of statins, and several laboratory values including albumin and total cholesterol. All PD patients who visited our clinic from January 2005 to September 2011 and who had complete medical records for at least 3 years were included. Among the 82 patients who met the criteria (mean period of observation: 1086 +/- 752 days; mean age: 62.0 +/- 12.3 years), 47 had experienced at least 1 episode of peritonitis. Aging was a significant risk factor for peritonitis, with a relative risk of 1.04 per year (p = 0.014). In our study, aging--rather than diabetes mellitus, efficiency of PD, or nutrition status--was an important risk factor for PD-associated peritonitis. Poor PD technique because of advanced age might be one of the reasons for this result.

RESUMEN

A broad consensus has not been reached on the appropriate timing for cessation of peritoneal dialysis (PD). Decreasing urine volume, repeated and refractory peritonitis, and deterioration of the peritoneal membrane are major reasons to stop PD. Also, the link between length of time on PD and encapsulating peritoneal sclerosis (EPS) should be an additional concern. The aim of the present study was to investigate patients who had been on continuous ambulatory PD (CAPD) for a long time. All patients undergoing CAPD at our kidney center for more than a decade from January 1990 to September 2011 were included in the study. Among more than 436 CAPD patients, 11 met the inclusion criteria. Their mean PD duration was 12.3 +/- 3.1 years. Mean age at CAPD introduction had been 46.0 +/- 10.1 years. All patients had nondiabetic nephropathy as the underlying cause of their end-stage renal disease. At least 2 of the 11 had developed EPS, and 1 had subsequently died from EPS. Patients on prolonged CAPD for more than a decade are still rare. The CAPD modality may be continued if it is efficiently maintained within an acceptable level, but EPS remains a serious complication of prolonged PD.

RESUMEN

Older adults face the concern of developing frailty and sarcopenia due to an inactive lifestyle during the coronavirus disease 2019 (COVID-19) pandemic. This study aimed to reveal the preventive behaviors taken by older adults who perceived a decline in physical fitness during COVID-19 and analyze the background factors which promoted such behaviors using a qualitative study design in 2020. The participants were recruited through the cohort study of Japanese older adults who were aged 79-81 and had not been diagnosed with sarcopenia previously in 2019 and perceived their physical fitness to have declined during the pandemic. The interviews of 19 participants were analyzed using thematic analysis. The participants engaged in five types of preventive behaviors to counter declining physical fitness: "walking", "exercising at home", "improving daily diet", "maintaining a daily routine", and "taking a good rest". Four themes were extracted pertaining to backgrounds of such preventive behaviors: "feeling anxiety and mental pressure", "available networks with family and neighbors", "prior experiences of behaviors", and "access to information". Anxiety due to lifestyle changes during the pandemic was the primary reason for the behaviors. This study can be a useful guide for undertaking possible measures to prevent frailty during future pandemics.

RESUMEN

AIM: To clarify older adults' preferences for and actual situations of artificial hydration and nutrition (AHN) in end-of-life care in a care home. METHODS: Participants were residents of a care home who had completed advance directives regarding preferred methods of AHN from 2009 to 2018. Advance directives alone were available from April 2009 to June 2016 (Wave 1), and advance care planning for AHN including advance directives was introduced in July 2016 (Wave 2). AHN preferences included (i) intensive methods (percutaneous endoscopic gastrostomy, nasogastric tube feeding and total parenteral nutrition), (ii) drip infusion, and (iii) oral intake only. Participants were followed until the end of 2020, and we checked whether decisions about AHN were based on older adults' preferences. RESULTS: In total, 272 participants had completed advance directives. Most participants preferred "oral intake only" (59.5%), followed by drip infusion (32.0%) and intensive methods (8.5%) in advance directives. Ninety of the 272 participants completed advance directives twice; 83.3% did not change their AHN preferences from Wave 1 to Wave 2. By the end of 2020, 93 of the 272 participants died in the care home. AHN was provided according to older adults' preferences in 48.9% (oral intake only), in 51.4% (drip infusion) and in 55.6% (intensive methods) of cases respectively. CONCLUSIONS: Most participants preferred oral intake only, and their preferences were reflected in decisions about actual situations of AHN in end-of-life care. To prepare for advanced dementia and senility, early advance care planning for AHN should be promoted. Geriatr Gerontol Int 2022; 22: 581-587.

RESUMEN

OBJECTIVES: Despite the reported 'male-female health-survival paradox', no components of the comprehensive geriatric assessment (CGA) routinely used in the field of geriatrics focus on female-specific symptoms. To investigate the impact of gynecological factors among elderly women, we noted the gynecological history and examined the association between self-rated symptoms of pelvic organ prolapse (POP) and CGA. STUDY DESIGN: This community-based, cross-sectional study in Japan included 164 community-dwelling women aged ≥75 years. MAIN OUTCOME MEASURES: The main outcome measures were the Pelvic Organ Prolapse Distress Inventory-6 (POPDI-6), activities of daily living (ADL), and Timed Up and Go (TUG) test. Self-rated symptoms of POP were assessed using POPDI-6, and the participants were dichotomized into POPDI-6 >0 (symptom group) and POPDI-6 = 0 (no-symptom group). Several components of the CGA were compared between the groups with and without symptoms of POP and the association with POPDI-6 score was analyzed by multiple logistic regression analysis. RESULTS: Compared with the no-symptom group, the symptom group had significantly longer TUG test time (≥13.5 s) (P = 0.024) and difficulty in basic ADL (score <21) (P = 0.02). In multiple logistic regression analysis, basic ADL <21 and TUG time ≥13.5 s were significantly associated with POPDI-6 >0 (odds ratio [OR] = 2.78; 95% confidence interval [CI] = 1.10-7.06 and OR = 3.45; 95% CI = 1.01-1.24). CONCLUSIONS: Self-rated POP symptoms were associated with CGA components among community-dwelling elderly women. Evaluating POP symptoms as part of the CGA could be meaningful for improving physical and psychological health in elderly women.

RESUMEN

Use of low-dose aspirin (LDA) is increasing with guideline recommendation for stroke prevention. The risk of gastrointestinal symptoms and bleeding with aspirin is dose-dependent, but still increases even at low doses. The principal treatment for NSAIDs-induced ulcer is discontinuation of NSAIDs use. However, discontinuation of LDA administration in stroke patients can increase the risk of stroke recurrence. Therefore, use of LDA cannot easily be discontinued. In patients who experience gastric intolerance to aspirin, options are to reduce the dose of aspirin to the minimum effective dose; to change to dispersable or enteric-coated preparations; to add concomitant gastro-protective drugs such as antacids, misoprostol, proton pump inhibitors, or H2-receptor antagonists; or to change to another antithrombotic agent: clopidogrel, cilostazol or warfarin if appropriate.
