Predictors for depressive symptoms by four types of disability

AbstractThis study aimed to examine the longitudinal relationship between disability and depressive symptoms, by comparing four types of disability in community-dwelling individuals with disabilities in South Korea. A total of 3347 South Koreans with disabilities from the second wave of the Panel Survey of Employment for the Disabled was utilized. Depressive symptomatology was assessed by whether the participant had experienced depressive symptoms for more than two weeks during the past year. A multivariate logistic regression model was used to calculate the odds ratio (OR) for depressive symptoms, and a Cox proportional hazards model to calculate the hazard ratio (HR) for two-year survival analysis. Persons who acquired mental disability from accident or industrial disaster and persons with congenital physical-internal disability were at higher risk for depressive symptoms. Maintaining employment was found to be an effective way to decrease the risk of depressive symptoms in persons with physical-external disability, sensory/speech disability, or mental disability. In contrast, in physical-internal disability, retaining normal ability to work seemed to be the key to reduce the risk of depressive symptoms. Predictors of depressive symptoms were found to differ depending on the type of disability. Such differences should be reflected in clinical and policy-level interventions to address the specific psychiatric needs of persons with different disabilities.

OBJECTIVE: The present study was conducted to assess the association between depressive symptomatology and mortality in chronic hemodialysis. METHOD: A cohort of 40 patients was followed for a median period of 10.5 months. The Beck Depression Inventory was used to classify patients as exposed to depression (Beck Depression Inventory score > 14) or not (Beck Depression Inventory < 14). Kaplan-Meier survival curves were used to compare the mortality rate between the two groups. The effects of potential confounding factors were adjusted using Cox proportional hazards model. RESULTS: After 24 months of follow-up, survival rates were 39% for exposed and 95% for non-exposed patients (p = 0.029). The Cox proportional hazards model showed results similar to those of the bivariate analysis, indicating that depressive symptomatology tended to be associated with mortality (HR = 6.5, 95%CI: 0.8-55.6; p = 0.085). Other study variables, including age, concurrent systemic diseases, and biochemical markers, were not significantly associated with mortality. Exposed patients remained on dialysis longer and received kidney transplants less frequently (9% vs. 50% for non-exposed patients). When kidney transplantation was included in the Cox regression model, the hazard ratio of mortality for exposed as compared to non-exposed patients lost statistical significance (HR = 4.5; 95%CI: 0.5-40.0; p = 0.17). CONCLUSIONS: Our study suggests that the presence of depressive symptoms may act as an independent risk factor for mortality in chronic hemodialysis patients. However, this finding needs further investigations.

Background In patients with cardiovascular diseases, inflammatory and hemostatic biomarkers are significant indicators of prognosis. We investigated whether circulating inflammatory and hemostatic biomarkers were predictive markers for all-cause death and cancer death in a population of community-dwelling Japanese. Methods We studied 1,920 healthy Japanese adults who underwent health examinations in 1999. Those who reported a history of inflammatory diseases and malignancy on a baseline questionnaire were excluded. Inflammatory and hemostatic biomarkers were measured in the remaining 1,862 participants, who were followed up periodically for 10 years. Multivariate proportional hazards regression analysis was used to estimate all-cause and cancer mortality. Results A total of 258 participants died during follow-up: 87 from cancer, 38 from cerebro-cardiovascular diseases, and 133 from other diseases. Mean C-reactive protein (CRP) levels at baseline were significantly higher in decedents than in survivors. Mean von Willebrand factor (vWF) levels at baseline were significantly higher in decedents than in survivors. The Cox proportional hazards model after adjustments for age and sex showed that CRP (hazard ratio [HR], 1.26; 95% confidence interval [CI], 1.06-1.51) and vWF (HR, 1.01; 95% CI, 1.00-1.01) were independent predictors of all-cause death. CRP (HR, 1.40; 95% CI, 1.06-1.86) and vWF (HR, 1.01; 95% CI, 1.00-1.02) were also independent predictive markers for cancer death. Conclusions Serum CRP and vWF were predictors of all-cause death and cancer death in the population of community dwelling Japanese.

Background. Little is known regarding the effects of socioeconomic status (SES) and frailty on mortality in Korea. Objective. This study investigated the combined impact of low SES and frailty on all-cause mortality in Korean older adults. Methods. Study sample at baseline comprised 7,960 community-dwelling adults (56.8% women) aged 65 years and older. The Cox proportional hazards model was used to estimate the hazard ratio (HR) and 95% confidence interval (CI) of low SES and frailty for all-cause mortality. Results. Overall, low SES plus frailty resulted in an increased risk of all-cause mortality (HR = 1.56, 95% CI = 1.09–2.23, P=0.015) even after adjustments for all the measured covariates, as compared with high SES plus nonfrailty (HR = 1). Among older adults aged 65–75 years, the increased mortality risk of either low SES plus nonfrailty (HR = 1.37, 95% CI = 1.02–1.84, P=0.038) or high SES plus frailty (HR = 2.09, 95% CI = 1.12–3.91, P=0.021) remained significant even after adjustments for all the covariates, as compared with high SES plus nonfrailty (HR = 1). Conclusion. The current findings suggest that either low SES or frailty is significantly associated with increased all-cause mortality in Korean older adults.

Abstract Background: Subjective cognitive decline (SCD) is a potential risk factor for dementia. We aimed to investigate the association between SCD and subsequent dementia in a nationwide population-based cohort in South Korea.Methods: This cohort included 579,710 66-year-old adults who completed a questionnaire about SCD and were followed-up for a total of 3,870,293 person-years (average 6.68 years per person). Hazard ratios were estimated using the Cox proportional hazards model and compared between subjects with and without SCD.Results: Compared to subjects without SCD, those with SCD were more likely to develop dementia (incidence per 100,000 person-years: no SCD: 566.14; SCD: 859.35). After adjusting for potential confounding factors, the risk of subsequent dementia significantly increased in subjects with SCD, with an adjusted hazard ratio (aHR) of 1.38 (95% confidence interval [CI] 1.34 to 1.41). The risk of subsequent dementia was greatly increased in subjects with higher SCD scores (aHR=2.77, 95% CI 2.47 to 3.11). A significant association between SCD and dementia was observed in both depressive and non-depressive symptom groups (aHR=1.50, 95% CI 1.42 to 1.57 in subjects with depressive symptoms; aHR=1.33, 95% CI 1.29 to 1.37 in subjects without depressive symptoms; P =0.001).Conclusions: In the participating 66-year-old population, SCD was significantly associated with an increased risk of subsequent dementia, independent of the presence of depressive symptoms. Our findings suggest that SCD indicates a risk for dementia. Further studies are needed to delineate potential approaches to preventing the development of dementia in individuals with SCD.

Abstract Background Although consuming a variety of foods is an internationally accepted recommendation for a healthy diet, little is known about the association between dietary variety and incident dementia. This study aimed to examine the association between dietary variety and incident disabling dementia in community-dwelling elderly Japanese adults. Methods We conducted a prospective study of 721 participants (age range: 65–97 years) of the 2012–2013 Kusatsu Longitudinal Study. Dietary variety was assessed based on a food frequency questionnaire that encompassed the 10 main food components of Japanese meals: meat, fish/shellfish, eggs, milk, soybean products, green/yellow vegetables, potatoes, fruit, seaweed, and fats/oils). Participants were then categorized into low (0–2 points), middle (3–5 points), and high (6–10 points) groups based on the scores. Data regarding incident disabling dementia were retrieved from the public Long-term Care Insurance database. The Cox proportional hazards model was used to estimate the hazard ratios (HRs) with 95% confidence intervals (CIs). Results During the median follow-up of 6.5 years, the incidence of disabling dementia was 9.3%. After adjusting for confounders, the multivariate HR for incident disabling dementia was 0.52 (95% CI, 0.27–1.00) for participants in the highest category of the dietary variety score compared to that for those in the lowest category. Conclusions Greater dietary variety is associated with a reduced risk of incident disabling dementia in elderly Japanese adults. Key messages Consuming a variety of foods may be necessary for dementia prevention.

Abstract Background Subjective cognitive decline (SCD) is a potential risk factor for dementia. We aimed to investigate the association between SCD and subsequent dementia in a nationwide population-based cohort in South Korea. Methods This cohort included 579,710 66-year-old adults who were followed for a total of 3,870,293 person-years (average 6.68±1.33 years per person). All subjects completed a questionnaire about subjective memory impairment, the Pre-screening Korean Dementia Screening Questionnaire (KDSQ-P), which included a validated 5-item derivative, and were determined to have SCD based on a single question assessing memory decline. Depressive symptoms were assessed in all subjects using a 3-item modified geriatric depression scale. Hazard ratios were estimated using the Cox proportional hazards model and compared between subjects with and without SCD. Results Compared to subjects without SCD, those with SCD were more likely to develop dementia (incidence per 1,000 person-years: non-SCD: 5.66; SCD: 8.59). After adjusting for potential confounding factors, the risk of subsequent dementia significantly increased in subjects with SCD, with an adjusted hazard ratio (aHR) of 1.38 (95% confidence interval [CI] 1.34 to 1.41). The risk of subsequent dementia was greatly increased in subjects with higher KDSQ-P scores (aHR = 2.77, 95% CI 2.47 to 3.11). A significant association between SCD and dementia was observed in both depressive and non-depressive symptom groups (aHR = 1.50, 95% CI 1.42 to 1.57 in subjects with depressive symptoms; aHR = 1.33, 95% CI 1.29 to 1.37 in subjects without depressive symptoms; P = 0.001). Conclusions In this population of 66-year-old individuals, SCD was significantly associated with an increased risk of subsequent dementia. This association was found in both depressive and non-depressive groups, with an increased risk of dementia in the presence of depressive symptoms. Our findings suggest that SCD indicates a risk for dementia. Further studies are needed to delineate potential approaches to preventing the development of dementia in individuals with SCD.

90 Background: The objective of this study was to evaluate the effect of radiation therapy (RT) on late cardiac death in patients with esophageal cancer. Methods: A total of 35,618 patients diagnosed with esophageal squamous cell carcinoma (SCC) or adenocarcinoma (ADE) between 1973 and 2008 were identified from the SEER database. After excluding records with missing data, 24983 patients remained. Patients who survived ≥ 5 years (2075) were identified for this analysis. Examined risk factors for cardiac death include age (≤55/56-65/66-75/>75), gender, race (white/non-white), stage (local/regional/distant), histology (SCC/ADE), esophageal subsite (<18cm/18-24cm/25-32cm/33-40cm), diagnosis year (1973-1983/1984-1993/1994-2003), and treatment with surgery or RT. Time to cardiac death was evaluated using the Kaplan-Meier method. A multivariate logistic regression model with backward elimination and the Cox Proportional Hazards model were used to evaluate risk factors for cardiac death. Results: Patients who received RT tended to be younger, white, diagnosed more recently, have more advanced disease, SCC histology and not undergo surgery. RT group had a higher risk of cardiac death than no-RT group (Log-Rank p < 0.0001). Median time to cardiac death in RT group was 251 months (95% CI 223-367) and was not reached in no-RT group. The probability of cardiac death increased with age and decreased with diagnosis year. This trend was more pronounced in RT group. Multivariate analysis found RT to be associated with higher probability of cardiac death (OR 1.45, 95% CI 1.10-1.93), after adjusting for age and diagnosis year. Gender, race, histology, stage, esophageal subsite and surgery status were not associated with cardiac death. After adjusting for age, Cox model showed that patients who received RT were more likely to die of cardiac causes than those who did not receive RT (HR 1.91, 95% CI 1.47-2.47). Diagnosis year was not a risk factor in the Cox model. Conclusions: Patients with esophageal cancer who received RT and survived ≥ 5 years had a higher risk of cardiac death than those who did not receive RT. Further study of cardiac outcome in long term survivors of esophageal cancer treated with RT, and accounting for comorbidity, is warranted.

Abstract Background Epidemiological evidence has shown that serum N-terminal pro-brain natriuretic peptide (NT-proBNP) concentrations, a diagnostic biomarker for heart failure, are positively associated with cardiovascular risk. Since NT-proBNP in serum is excreted in urine, it is hypothesized that urinary NT-proBNP concentrations are correlated with serum concentrations and linked with cardiovascular risk in the general population. Methods A total of 3060 community-dwelling residents aged ≥ 40 years without history of cardiovascular disease (CVD) were followed up for a median of 8.3 years (2007–2015). Serum and urinary concentrations of NT-proBNP at baseline were compared. The hazard ratios (HRs) and their 95% confidence intervals (CIs) for the association between NT-proBNP concentrations and the risk of developing CVD were computed using the Cox proportional hazards model. Results The median values (interquartile ranges) of serum and urinary NT-proBNP concentrations at baseline were 56 (32–104) pg/mL and 20 (18–25) pg/mL, respectively. There was a strong quadratic correlation between the serum and urinary concentrations of NT-proBNP (coefficient of determination [R2] = 0.72): urinary concentrations of 20, 27, and 43 pg/mL were equivalent to serum concentrations of 55, 125, and 300 pg/mL, respectively. During the follow-up period, 170 subjects developed CVD. The age- and sex-adjusted risk of CVD increased significantly with higher urinary NT-proBNP levels (P for trend < 0.001). This association remained significant after adjustment for traditional cardiovascular risk factors (P for trend = 0.009). The multivariable-adjusted risk of developing CVD almost doubled in subjects with urinary NT-proBNP of ≥ 43 pg/mL as compared to those with urinary NT-proBNP of ≤ 19 pg/mL (HR 2.07, 95% CI 1.20–3.56). Conclusions The present study demonstrated that urinary NT-proBNP concentrations were well-correlated with serum concentrations and were positively associated with cardiovascular risk. Given that urine sampling is noninvasive and does not require specially trained personnel, urinary NT-proBNP concentrations have the potential to be an easy and useful biomarker for detecting people at higher cardiovascular risk.

Abstract. Background: We investigated the age at exposure to parental suicide and the risk of subsequent suicide completion in young people. The impact of parental and offspring sex was also examined. Method: Using a cohort study design, we linked Taiwan's Birth Registry (1978–1997) with Taiwan's Death Registry (1985–2009) and identified 40,249 children who had experienced maternal suicide (n = 14,431), paternal suicide (n = 26,887), or the suicide of both parents (n = 281). Each exposed child was matched to 10 children of the same sex and birth year whose parents were still alive. This yielded a total of 398,081 children for our non-exposed cohort. A Cox proportional hazards model was used to compare the suicide risk of the exposed and non-exposed groups. Results: Compared with the non-exposed group, offspring who were exposed to parental suicide were 3.91 times (95% confidence interval [CI] = 3.10–4.92 more likely to die by suicide after adjusting for baseline characteristics. The risk of suicide seemed to be lower in older male offspring (HR = 3.94, 95% CI = 2.57–6.06), but higher in older female offspring (HR = 5.30, 95% CI = 3.05–9.22). Stratified analyses based on parental sex revealed similar patterns as the combined analysis. Limitations: As only register-based data were used, we were not able to explore the impact of variables not contained in the data set, such as the role of mental illness. Conclusion: Our findings suggest a prominent elevation in the risk of suicide among offspring who lost their parents to suicide. The risk elevation differed according to the sex of the afflicted offspring as well as to their age at exposure.

OBJECTIVEThe aim of this study was to investigate the relationship between extent of resection (EOR) and survival in terms of clinical, molecular, and radiological factors in high-grade astrocytoma (HGA).METHODSClinical and radiological data from 585 cases of molecularly defined HGA were reviewed. In each case, the EOR was evaluated twice: once according to contrast-enhanced T1-weighted images (CE-T1WI) and once according to fluid attenuated inversion recovery (FLAIR) images. The ratio of the volume of the region of abnormality in CE-T1WI to that in FLAIR images (VFLAIR/VCE-T1WI) was calculated and a receiver operating characteristic curve was used to determine the optimal cutoff value for that ratio. Univariate and multivariate analyses were performed to identify the prognostic value of each factor.RESULTSBoth the EOR evaluated from CE-T1WI and the EOR evaluated from FLAIR could divide the whole cohort into 4 subgroups with different survival outcomes (p < 0.001). Cases were stratified into 2 subtypes based on VFLAIR/VCE-T1WIwith a cutoff of 10: a proliferation-dominant subtype and a diffusion-dominant subtype. Kaplan-Meier analysis showed a significant survival advantage for the proliferation-dominant subtype (p < 0.0001). The prognostic implication has been further confirmed in the Cox proportional hazards model (HR 1.105, 95% CI 1.078–1.134, p < 0.0001). The survival of patients with proliferation-dominant HGA was significantly prolonged in association with extensive resection of the FLAIR abnormality region beyond contrast-enhancing tumor (p = 0.03), while no survival benefit was observed in association with the extensive resection in the diffusion-dominant subtype (p=0.86).CONCLUSIONSVFLAIR/VCE-T1WIis an important classifier that could divide the HGA into 2 subtypes with distinct invasive features. Patients with proliferation-dominant HGA can benefit from extensive resection of the FLAIR abnormality region, which provides the theoretical basis for a personalized resection strategy.
