AIM: Aging-associated CI can impair the ability of individuals to perform a VF test and compromise the reliability of the results. We evaluated the association between neurocognitive impairment and VF reliability indices in glaucoma patients.
METHODS: This prospective, cross-sectional study was conducted in the Ophthalmology Department, Hospital Kuala Pilah, Malaysia, and included 113 eyes of 60 glaucoma patients with no prior diagnosis of dementia. Patients were monitored with the Humphrey Visual Field Analyzer using a 30-2 SITA, standard protocol, and CI was assessed using the clock drawing test (CDT). The relationships between the CDT score, MD, pattern standard deviation, Visual Field Index (VFI), fixation loss (FL), false-positive values, and FN values were analyzed using the ordinal regression model.
RESULTS: Glaucoma patients older than 65 years had a higher prevalence of CI. There was a statistically significant correlation between CDT scores and glaucoma severity, FL, FN, and VFI values (rs=-0.20, P=0.03; rs=-0.20, P=0.04; rs=-0.28, P=0.003; rs=0.21, P=0.03, respectively). In a multivariate model adjusted for age and glaucoma severity, patients with lower FN were significantly less likely to have CI (odds ratio, 0.91; 95% confidence interval, 0.89-0.93) and patients with higher MD were more likely to have CI (odds ratio, 1.10; 95% confidence interval, 1.05-1.16); false positive, FL, pattern standard deviation, and VFI showed no significant correlation.
CONCLUSION: Cognitive decline is associated with reduced VF reliability, especially with higher FN rate and overestimated MD. Screening and monitoring of CI may be important in the assessment of VF progression in glaucoma patients.
METHODS AND RESULTS: For 12 years, we followed a prospective nationwide cohort of 15 151 patients (aged 22-101 years, median age 63 years; 72.3% male; 66.7% Chinese, 19.8% Malay, 13.5% Indian) who were hospitalized for acute myocardial infarction between 2000 and 2005. There were 6463 deaths (4534 cardiovascular, 1929 noncardiovascular). Compared with men, women had a higher risk of cardiovascular death (age-adjusted hazard ratio [HR] 1.3, 95% CI 1.2-1.4) but a similar risk of noncardiovascular death (HR 0.9, 95% CI 0.8-1.0). Sex differences in cardiovascular death varied by ethnicity, age, and time. Compared with Chinese women, Malay women had the greatest increased hazard of cardiovascular death (HR 1.4, 95% CI 1.2-1.6) and a marked imbalance in death due to heart failure or cardiomyopathy (HR 3.4 [95% CI 1.9-6.0] versus HR 1.5 [95% CI 0.6-3.6] for Indian women). Compared with same-age Malay men, Malay women aged 22 to 49 years had a 2.5-fold (95% CI 1.6-3.8) increased hazard of cardiovascular death. Sex disparities in cardiovascular death tapered over time, least among Chinese patients and most among Indian patients; the HR comparing cardiovascular death of Indian women and men decreased from 1.9 (95% CI 1.5-2.4) at 30 days to 0.9 (95% CI 0.5-1.6) at 10 years.
CONCLUSION: Age, ethnicity, and time strongly influence the association between sex and specific cardiovascular causes of mortality, suggesting that health care policy to reduce sex disparities in acute myocardial infarction outcomes must consider the complex interplay of these 3 major modifying factors.
MATERIALS AND METHODS: A cross sectional study adopting the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) was conducted. All cancer patients attending Penang General Hospital between August-November 2011 were approached. Descriptive statistics were used to assess demographic and disease related characteristics of the patients. All analyses were performed using SPSS v 16.0.
RESULTS: Three hundred and ninety three cancer patients met the inclusion criteria and were enrolled in the study. The mean age was 53.9 (SD±13) years. The cohort was dominated by females (n=260, 66.2%). Nearly half (n=190, 48.3%) of the participants were of Malay ethnicity, practicing Islam as their religion (n=194, 49.4%). Two hundred and ninety six (n=296, 75.3%) had beene diagnosed with cancer within six months to 3 years previously. The most common primary cancer site was breast (n=143, 36.4%). The mean Global Health Status (GHS) score was 60.7 (SD=21.3). Females (mean GHS score of 62.3, p=0.035) with Malay ethnicity (mean GHS score of 63.8, p=0.047), practicing Islam as their religion (mean GHS score of 63.0, p=0.011) had better GHS scores. Patients having medical insurance had good scores (mean 65.6, p=0.021). Marital status was significantly associated with GHS scores (p=0.022). Bone cancer patientshad the lowest mean GHS score of 49.2 (p=0.044). Patients at very advanced stages of cancer featured a low GHS mean score of 52.2 (p<0.001).
CONCLUSIONS: The present study identified many demographic and disease related factors which may contribute to the HRQoL of cancer patients, pointing to the necessity for improved management of disease symptoms and provision of psychological and financial support.
