Objectives: The sociocultural model of stress and coping, which despite receiving support from several studies conducted with diverse ethnic groups, has yet to be tested longitudinally or used within the context of positive caregiver outcomes. The aim of the current study was to test a specific component of the model, which posits that caregiver coping will be influenced by the cultural value of familism (feelings of solidarity and loyalty among family members), which will in turn affect caregiver outcomes.
Method: A questionnaire was completed by 123 family caregivers in the UK assessing familism, use of coping strategies, caregiver gains, anxiety and depression at three time points over nine months.
Results: Mediation analysis followed guidelines proposed by Baron and Kenny. Religious coping and positive reframing at time 2 (T2) were found to significantly mediate between familism values at time 1 (T1) and caregiver gains at time 3 (T3). Behavioural disengagement at T2 was found to mediate between familism at T1 and caregiver depression atT3. Additionally familism was found to be positively associated with both negative and positive aspects of caregiving.
Conclusion: Our longitudinal findings suggest that interventions and services acknowledging caregiver values and the associated coping responses may prove beneficial. 相似文献
While two-stage revision is the gold standard for treatment of knee prosthetic joint infection (PJI), it is not without risk. The purpose of this study was to develop a tool to preoperatively predict the probability that a two-stage revision would fail to eradicate knee PJI. 3,809 surgical cases were retrospectively reviewed and data were collected from 314 charts. Overall, 105 (33.4%) cases failed to eradicate PJI using this procedure. Univariate analysis identified multiple variables independently associated with reinfection. Logistic regression was used to generate a model (bootstrap-corrected concordance index of 0.773) predicting failure of infection eradication. Preoperative knowledge of a high probability of failure may improve risk assessment, lead to more aggressive management, and allow for time to consider alternative therapies. 相似文献
Soy foods are the richest sources of isoflavones, mainly daidzein and genistein. Soy isoflavones are structurally similar to the steroid hormone 17β-estradiol and may protect against breast cancer. S-(−)equol, a metabolite of the soy isoflavone daidzein, has a higher bioavailability and greater affinity for estrogen receptor β than daidzein. Approximately one-third of the Western population is able to produce S-(−)equol, and the ability is linked to certain gut microbes. We hypothesized that the prevalence of breast cancer, ductal hyperplasia, and overall breast pathology will be lower among S-(−)equol producing, as compared with nonproducing, postmenopausal women undergoing a breast biopsy. We tested our hypothesis using a cross-sectional study design. Usual diets of the participants were supplemented with 1 soy bar per day for 3 consecutive days. Liquid chromatography–multiple reaction ion monitoring mass spectrometry analysis of urine from 143 subjects revealed 25 (17.5%) as S-(−)equol producers. We found no statistically significant associations between S-(−)equol producing status and overall breast pathology (odds ratio [OR], 0.68; 95% confidence interval [CI], 0.23-1.89), ductal hyperplasia (OR, 0.84; 95% CI, 0.20-3.41), or breast cancer (OR, 0.56; 95% CI, 0.16-1.87). However, the mean dietary isoflavone intake was much lower (0.3 mg/d) than in previous reports. Given that the amount of S-(−)equol produced in the gut depends on the amount of daidzein exposure, the low soy intake coupled with lower prevalence of S-(−)equol producing status in the study population favors toward null associations. Findings from our study could be used for further investigations on S-(−)equol producing status and disease risk. 相似文献
