A patient perspective of the impact of medication side effects on adherence: results of a cross-sectional nationwide survey of patients with schizophrenia

<p>Abstract</p> <p>Background</p> <p>Antipsychotic medications often have a variety of side effects, however, it is not well understood how the presence of specific side effects correlate with adherence in a real-world setting. The aim of the current study was to examine the relationship between these variables among community-dwelling patients with schizophrenia.</p> <p>Methods</p> <p>Data were analyzed from a 2007-2008 nationwide survey of adults who self-reported a diagnosis of schizophrenia and were currently using an antipsychotic medication (N = 876). The presence of side effects was defined as those in which the patient reported they were at least "somewhat bothered". Adherence was defined as a score of zero on the Morisky Medication Adherence Scale. To assess the relationship between side effects and adherence, individual logistic regression models were fitted for each side effect controlling for patient characteristics. A single logistic regression model assessed the relationship between side effect clusters and adherence. The relationships between adherence and health resource use were also examined.</p> <p>Results</p> <p>A majority of patients reported experiencing at least one side effect due to their medication (86.19%). Only 42.5% reported complete adherence. Most side effects were associated with a significantly reduced likelihood of adherence. When grouped as side effect clusters in a single model, extra pyramidal symptoms (EPS)/agitation (odds ratio (OR) = 0.57, p = 0.0007), sedation/cognition (OR = 0.70, p = 0.033), prolactin/endocrine (OR = 0.69, p = 0.0342), and metabolic side effects (OR = 0.64, p = 0.0079) were all significantly related with lower rates of adherence. Those who reported complete adherence to their medication were significantly less likely to report a hospitalization for a mental health reason (OR = 0.51, p = 0.0006), a hospitalization for a non-mental health reason (OR = 0.43, p = 0.0002), and an emergency room (ER) visit for a mental health reason (OR = 0.60, p = 0.008).</p> <p>Conclusions</p> <p>Among patients with schizophrenia, medication side effects are highly prevalent and significantly associated with medication nonadherence. Nonadherence is significantly associated with increased healthcare resource use. Prevention, identification, and effective management of medication-induced side effects are important to maximize adherence and reduce health resource use in schizophrenia.</p

Impact of age and comorbidities on health-related quality of life for patients with prostate cancer: evaluation before a curative treatment

<p>Abstract</p> <p>Background</p> <p>Interpretation of comparative health-related quality of life (HRQOL) studies following different prostate cancer treatments is often difficult due to differing patient ages. Furthermore, age-related changes can hardly be discriminated from therapy-related changes. The evaluation of age-and comorbidity-related changes was in focus of this study.</p> <p>Methods</p> <p>HRQOL of 528 prostate cancer patients was analysed using a validated questionnaire (Expanded Prostate Cancer Index Composite) before a curative treatment. Patients were divided into age groups ≤65, 6670, 7175 and >75 years. The impact of specific comorbidities and the Charlson Comorbidity Index (CCI) were evaluated. The questionnaire comprises 50 items concerning the urinary, bowel, sexual and hormonal domains for function and bother. For assessment of sexual and hormonal domains, only patients without prior hormonal treatment were included (n = 336).</p> <p>Results</p> <p>Urinary incontinence was observed increasingly with higher age (mean function scores of 92/88/85/87 for patients ≤65, 6670, 7175 and >75 years) complete urinary control in 78%/72%/64%/58% (p < 0.01). Sexual function scores decreased particularly (48/43/35/30), with erections sufficient for intercourse in 68%/50%/36%/32% (p < 0.01) a decrease of more than a third comparing patients ≤65 vs. 6670 (36%) and 6670 vs. 7175 years (39%). The percentage of patients with comorbidities was lowest in the youngest group (48% vs. 66%/68%/63% for ages 6670/7175/>75 years; p < 0.05). A multivariate analysis revealed an independent influence of both age and comorbidities on urinary incontinence, specifically diabetes on urinary bother, and both age and diabetes on sexual function/bother. Rectal domain scores were not significantly influenced by age or comorbidities. A CCI>5 particularly predisposed for lower urinary and sexual HRQOL scores.</p> <p>Conclusion</p> <p>Urinary continence and sexual function are the crucial HRQOL domains with age-related and independently comorbidity-related decreasing scores. The results need to be considered for the interpretation of comparative studies or longitudinal changes after a curative treatment.</p

EFFECT OF POLYPHENOL CONCENTRATIONS ON ASTRINGENCY PERCEPTION AND ITS CORRELATION WITH GELATIN INDEX OF RED WINE

The aims of this work were to investigate the effect of polyphenol concentrations on astringency perception and gelatin index measurements in noncommercial red wines, as well as evaluate astringency evolution over time. Spearman coefficients showed a positive correlation between polyphenols at low concentration with gelatin index (P < 0.001), and astringency (P < 0.05). Gelatin index values and polyphenol concentrations were related by a power function at low polyphenol levels, but no correlation was shown when total polyphenol levels overcame 5.20 g/L. Similar relationships were found between perceived astringency/gelatin index, and astringency/polyphenol concentrations. It was evident that gelatin index was a better estimator of astringency when polyphenol levels were low, and astringency intensity did not increase when polyphenol concentrations were higher than 5.20 g/L. Timeintensity measurements of astringency showed that maximum intensity governed the evolution of sensation.Fil: Goldner, Maria Cristina.

Parents’ years in Sweden and children’s educational performance

This paper assesses the intergenerational effect of immigrant parents’ incorporation experiences, measured as time in Sweden, on the educational performance of their children, using full Swedish population registry data for 22 cohorts. Employing family fixed-effects, we examine final course grades and national standardized test scores in Swedish and math by parents’ country of origin. Results show a positive effect of parents’ time in Sweden on their children’s performance in Swedish, but not for math performance. These results demonstrate the importance of parents’ linguistic acculturation on their children’s educational performance. Jel codes: I21, J15, J6

Quality of life in women with breast cancer, after surgical intervention, in a city in the zona da mata region in Minas Gerais, Brazil

Objectives: To evaluate health-related quality of life (HRQoL) in women with breast cancer, after surgical intervention, attended at the regional Oncology Referral Hospital in Juiz de Fora (MG). Methods: 121 women were evaluated and the European Organization for Research and Treatment of Cancer, Breast Cancer-Specific Quality of Life Questionnaire (EORTC QLC 30 BR23) was applied. After the descriptive analysis, a multiple linear regression model was created. The SPSS 14 was used to build the database and to conduct the analysis. Results: the mean values of the EORTC QLC 30 BR23 showed a tendency for good HRQoL, thus, the functional scale showed the most impairment with the worst mean scores observed. There was statistical significance among the symptoms scale and obese women who underwent adjuvant radiotherapy and those who had a greater number of dissected lymph nodes. The subjective perceptions influenced all the EORTC QLC 30 BR23domains. Conclusions: after controlling the variable by functional hand, and time of surgery, the BMI variables, breast reconstruction, heavy feeling in the arm, range of motion (ROM) reduction of the shoulder, and the tight shirt-sleeve sensation proven capable of explaining HRQoL. HRQoL appears to be relatively good, but negatively influenced by subjective perceptions, in addition to treatment factors.
