The effectiveness of cognitive behavioural therapy for depression in women with breast cancer: a systematic review and meta-analysis.

BACKGROUND: Depression is a common co-morbidity in women with breast cancer. Previous systematic reviews investigating cognitive behavioural therapy (CBT) for depression in this population based their conclusions on findings from studies with varying and often limited specificity, quality and/or quantity of CBT within their interventions. AIM: To determine the effectiveness of a specific, well-evidenced CBT protocol for depression in women with breast cancer. METHOD: Online databases were systematically searched to identify randomised controlled trials (RCTs) testing CBT (aligned to Beck's protocol) as a treatment for depression in women with breast cancer. Screening, data extraction and risk of bias assessment were independently undertaken by two study authors. Both narrative synthesis and meta-analysis were used to analyse the data. The meta-analysis used a random effects model to compare CBT with non-active/active controls of depression using validated, self-report measures. RESULTS: Six RCTs were included in the narrative synthesis, and five in the meta-analysis (n = 531 participants). Overall, CBT demonstrated an improvement in depression scores in the CBT condition versus active and non-active controls at post-intervention (SMD = -0.93 [95% CI -1.47, -0.40]). Narratively, five out of six RCTs reported statistically significant improvements in depression symptoms for CBT over control conditions for women with breast cancer. CONCLUSION: CBT aligned to Beck's protocol for depression appears effective for treating depression in women with breast cancer. However, further research is needed for women with stage IV breast cancer. The clinical recommendation is that therapists utilise Beck's CBT protocol for depression, whilst considering the complex presentation and adapt their practice accordingly.

Adequacy of thyroid hormone replacement for people with hypothyroidism in real-world settings: A systematic review and meta-analysis of observational studies.

OBJECTIVE: Thyroid hormone under-replacement and over-replacement are associated with adverse health outcomes. This systematic review aimed to evaluate the extent of thyroid hormone replacement adequacy for patients with known hypothyroidism in real-word settings, excluding those receiving thyroid hormone suppressive therapy as thyroid cancer treatment. DESIGN: Four electronic databases (Embase [Ovid], Medline [Ovid], PubMed and SCOPUS) were searched for published and unpublished observational studies until 12 December 2022. The results of the studies were meta-analysed to calculate pooled prevalence estimates for thyroid hormone supplementation adequacy, over-replacement and under-replacement. Quality assessment of studies was performed using the Joanna-Briggs appraisal tool for prevalence studies. RESULTS: Seven studies with a total of 4230 patients were eligible for quantitative synthesis. The pooled prevalence estimates of adequate thyroid replacement, over-replacement and under-replacement were 0.55 (95% confidence interval [CI]: 0.49-0.60, p = .001), 0.20 (95% CI: 0.14-0.27, p = .001) and 0.24 (95% CI: 0.13-0.36, p = .001), respectively. Four studies subclassified hypothyroidism and hyperthyroidism into overt and subclinical. The pooled prevalence of overt and subclinical hyperthyroidism was 0.04 (95% CI: 0.00-0.11, p = .01) and 0.17 (95% CI: 0.09-0.27 p = .001), respectively. For overt and subclinical hypothyroidism, the pooled prevalence was 0.02 (95% CI: 0.01-0.03, p = .001) and 0.20 (95% CI: 0.12-0.29, p = .001), respectively. CONCLUSIONS: On average, approximately half of patients with hypothyroidism are only treated to target euthyroidism. In real-world practice, a significant number of patients are over-treated or under-treated, leading to adverse healthcare outcomes. It is imperative that more effective thyroid monitoring strategies be implemented, with an emphasis on primary care thyroid function monitoring, to minimise inappropriate thyroid replacement treatments and optimise healthcare outcomes at a population level.

Illness perceptions, illness-related problems, subjective health and the role of perceived primal threat: preliminary findings.

Many theories suggest that a threatening situation impacts health because it affects core needs. Our assumption was that a set of interdependent ;perceived primal threats' to basic human needs (self-preservation, social integration, personal identity and growth, and positive worldview), which result from the presence of a disease, are related to illness perceptions and subjective health. Participants were 121 chronic medical patients. According to the results, perceived primal threat was strongly associated with illness-related perceptions and problems, as well as perceived psychological and overall self-rated health. Also, perceived primal threat mediated the relationship between illness-related factors and subjective health measures.
