Predictors of outcome for telephone and face-to-face administered cognitive behavioral therapy for depression.

BACKGROUND: Cognitive behavioral therapy (CBT) can be delivered efficaciously through various modalities, including telephone (T-CBT) and face-to-face (FtF-CBT). The purpose of this study was to explore predictors of outcome in T-CBT and FtF-CBT for depression. METHOD: A total of 325 depressed participants were randomized to receive eighteen 45-min sessions of T-CBT or FtF-CBT. Depression severity was measured using the Hamilton Depression Rating Scale (HAMD) and the Patient Health Questionnaire-9 (PHQ-9). Classification and regression tree (CART) analyses were conducted with baseline participant demographics and psychological characteristics predicting depression outcomes, HAMD and PHQ-9, at end of treatment (week 18). RESULTS: The demographic and psychological characteristics accurately identified 85.3% and 85.0% of treatment responders and 85.7% and 85.0% of treatment non-responders on the HAMD and PHQ-9, respectively. The Coping self-efficacy (CSE) scale predicted outcome on both the HAMD and PHQ-9; those with moderate to high CSE were likely to respond with no other variable influencing that prediction. Among those with low CSE, depression severity influenced response. Social support, physical functioning, and employment emerged as predictors only for the HAMD, and sex predicted response on the PHQ-9. Treatment delivery method (i.e. telephone or face-to-face) did not impact the prediction of outcome. CONCLUSIONS: Findings suggest that the predictors of improved depression are similar across treatment modalities. Most importantly, a moderate to high level of CSE significantly increases the chance of responding in both T-CBT and FtF-CBT. Among patients with low CSE, those with lower depressive symptom severity are more likely to do well in treatment.

Efficacy of a sun protection workbook for kidney transplant recipients: a randomized controlled trial of a culturally sensitive educational intervention.

A culturally sensitive educational intervention that encouraged sun protection behaviors among kidney transplant recipients (KTRs) was developed and the short-term efficacy was evaluated. Non-Hispanic White, Hispanic/Latino and non-Hispanic Black patients, who received a transplant 2-24 months prior to the study, were randomized into two study groups: intervention versus standard of care. Electronic reminders tailored to the weather conditions were sent every 2 weeks by text message or email. Self-reported surveys and biologic measurements were obtained prior to the intervention and 6 weeks later. Among the 101 study participants, there was a statistically significant increase in knowledge, recognition of personal risk of developing skin cancer, willingness to change sun protection behavior and self-reported performance of sun protection in participants receiving the intervention in comparison with those receiving standard of care (p < 0.05). The pigment darkening of the sun-exposed forearm and sun damage of the forearm and sunburns/skin irritation from the sun were significantly less in participants receiving the intervention (p < 0.05). Providing sun protection education at the beginning of summer with reminders tailored to weather conditions helped KTRs adopt sun protection practices. This sun protection program for KTRs may be incorporated into the care provided by the nephrologist or transplant surgeon.

Blood transcriptomic biomarkers in adult primary care patients with major depressive disorder undergoing cognitive behavioral therapy.

An objective, laboratory-based diagnostic tool could increase the diagnostic accuracy of major depressive disorders (MDDs), identify factors that characterize patients and promote individualized therapy. The goal of this study was to assess a blood-based biomarker panel, which showed promise in adolescents with MDD, in adult primary care patients with MDD and age-, gender- and race-matched nondepressed (ND) controls. Patients with MDD received cognitive behavioral therapy (CBT) and clinical assessment using self-reported depression with the Patient Health Questionnaire-9 (PHQ-9). The measures, including blood RNA collection, were obtained before and after 18 weeks of CBT. Blood transcript levels of nine markers of ADCY3, DGKA, FAM46A, IGSF4A/CADM1, KIAA1539, MARCKS, PSME1, RAPH1 and TLR7, differed significantly between participants with MDD (N=32) and ND controls (N=32) at baseline (q< 0.05). Abundance of the DGKA, KIAA1539 and RAPH1 transcripts remained significantly different between subjects with MDD and ND controls even after post-CBT remission (defined as PHQ-9 <5). The ROC area under the curve for these transcripts demonstrated high discriminative ability between MDD and ND participants, regardless of their current clinical status. Before CBT, significant co-expression network of specific transcripts existed in MDD subjects who subsequently remitted in response to CBT, but not in those who remained depressed. Thus, blood levels of different transcript panels may identify the depressed from the nondepressed among primary care patients, during a depressive episode or in remission, or follow and predict response to CBT in depressed individuals.

Do positive or negative stressful events predict the development of new brain lesions in people with multiple sclerosis?

BACKGROUND: Stressful life events have long been suspected to contribute to multiple sclerosis (MS) disease activity. The few studies examining the relationship between stressful events and neuroimaging markers have been small and inconsistent. This study examined whether different types of stressful events and perceived stress could predict the development of brain lesions. METHOD: This was a secondary analysis of 121 patients with MS followed for 48 weeks during a randomized controlled trial comparing stress management therapy for MS (SMT-MS) to a waitlist control (WLC). Patients underwent magnetic resonance imaging (MRI) scans every 8 weeks. Every month, patients completed an interview measure assessing stressful life events and self-report measures of perceived stress, anxiety and depressive symptoms, which were used to predict the presence of gadolinium-enhancing (Gd+) and T2 lesions on MRI scans 29-62 days later. Participants classified stressful events as positive or negative. Negative events were considered 'major' if they involved physical threat or threat to the patient's family structure, and 'moderate' otherwise. RESULTS: Positive stressful events predicted decreased risk for subsequent Gd+ lesions in the control group [odds ratio (OR) 0.53 for each additional positive stressful event, 95% confidence interval (CI) 0.30-0.91] and less risk for new or enlarging T2 lesions regardless of group assignment (OR 0.74, 95% CI 0.55-0.99). Across groups, major negative stressful events predicted Gd+ lesions (OR 1.77, 95% CI 1.18-2.64) and new or enlarging T2 lesions (OR 1.57, 95% CI 1.11-2.23) whereas moderate negative stressful events, perceived stress, anxiety and depressive symptoms did not. CONCLUSIONS: Major negative stressful events predict increased risk for Gd+ and T2 lesions whereas positive stressful events predict decreased risk.

Patient reported outcomes and analgesia use in osteoarthritis of the knee.

OBJECTIVE: Non-opioid analgesics (NOAs) are widely used to palliate osteoarthritis (OA) pain, however, their role in health-related quality of life (HRQoL) in OA has not been well studied. Here, we assess the relationship of pain, physical function, and HRQoL to NOA use in symptomatic knee OA. METHODS: NOA dose, pain, physical function, and HRQoL were evaluated longitudinally over 1 year in medial knee OA. Doses provided by subjects' weekly medication diaries were normalized to equi-analgesic ibuprofen-equivalents (IEs). Descriptive analyses at baseline, 1.5, and 12 months, and non-parametric comparisons of NOA with pain, physical function, and HRQoL at 1.5 months and over 12 months were performed. RESULTS: Seventy-one subjects (19 males and 52 females; mean 57+/-10.5 years) used an overall median of 300 mg/week of IE. Twenty-five subjects reported no analgesic use during the study; of the 46 subjects that reported NOA use, the median intake was 1325 mg/week IE. Whereas age, Physical Functioning (PF) and HRQoL were predictive of NOA dose both at 1.5 months and during the entire study, pain level was not. The median NOA dose declined over 12 months (P=0.02), however, the change was not associated with changes in PF, HRQoL or pain. CONCLUSION: Greater age and worse physical function and HRQoL, but not pain severity, are predictive of NOA use in symptomatic knee OA. Longitudinally, NOA use does not change as a function of pain. These data suggest that pain is not the primary determinant of NOA use over time among OA patients.
