Predictors of improvement in an open-trial multisite evaluation of emotion regulation group therapy.

Emotion regulation group therapy (ERGT) is a novel treatment specifically targeting deliberate non-suicidal self-harm (DSH) in individuals with borderline personality disorder (BPD). Identifying robust predictors of positive response to ERGT could aid clinicians in treatment selection; however, to date, only one such study has been conducted. Thus, we aimed to replicate previously identified predictors of treatment response to ERGT by investigating demographic, clinical, and diagnostic predictors in 95 women with BPD or subclinical BPD who had participated in an open-trial evaluation of ERGT. Outcomes evaluated were frequency of DSH and emotion dysregulation. Assessments were conducted at pretreatment, post-treatment, and 6-month follow-up. Multilevel mixed linear models and multilevel negative binomial generalized estimated equations were used to identify significant interactions between the predictors and outcomes. We found that greater pretreatment DSH frequency was associated with greater improvements in DSH during treatment (b = 0.998, SE = 0.00, p = 0.03) and follow-up (b = 0.997, SE = 0.00, p < 0.01) and that greater BPD severity was associated with greater improvements in DSH during treatment (b = 0.84, SE = 0.06, p = 0.02) and in emotion dysregulation at follow-up (b = -3.05, SE = 1.47, p = 0.04). Co-occurring disorders were associated with poorer treatment response during follow-up. Results were generally consistent with a previous study of the predictors of response to ERGT. The findings provide further support for the utility of this treatment across a range of BPD patients, including patients with severe DSH and BPD.

How to optimize current treatment of genotype 2 hepatitis C virus infection.

The standard of care (SOC) for hepatitis C virus (HCV) genotype 2 is pegylated interferon (PEG-IFN) plus ribavirin (RBV). Even though most patients can be cured with this therapy after 24 weeks, tailoring treatment can improve its safety and efficacy in special populations. Thus, shortening treatment together with a weight-based RBV dosing approach has been considered satisfactory in patients with positive predictors of response. With the development of the direct antiviral agents (DAAs), shorter, better tolerated and more efficient treatments for HCV genotype 2 will become available, including interferon-free regimens. Until these new treatments are released, the decision to treat patients with HCV genotype 2 with currently approved drugs or to wait for future options must be made, taking into account the stage of fibrosis.

Cold Cognition as Predictor of Treatment Response to rTMS; A Retrospective Study on Patients With Unipolar and Bipolar Depression.

Background: Cognitive impairments are prevalent in patients with unipolar and bipolar depressive disorder (UDD and BDD, respectively). Considering the fact assessing cognitive functions is increasingly feasible for clinicians and researchers, targeting these problems in treatment and using them at baseline as predictors of response to treatment can be very informative. Method: In a naturalistic, retrospective study, data from 120 patients (Mean age: 33.58) with UDD (n = 56) and BDD (n = 64) were analyzed. Patients received 20 sessions of bilateral rTMS (10 Hz over LDLPFC and 1 HZ over RDLPFC) and were assessed regarding their depressive symptoms, sustained attention, working memory, and executive functions, using the Beck Depression Inventory (BDI-II) and Neuropsychological Test Automated Battery Cambridge, at baseline and after the end of rTMS treatment course. Generalized estimating equations (GEE) and logistic regression were used as the main statistical methods to test the hypotheses. Results: Fifty-three percentage of all patients (n = 64) responded to treatment. In particular, 53.1% of UDD patients (n = 34) and 46.9% of BDD patients (n = 30) responded to treatment. Bilateral rTMS improved all cognitive functions (attention, working memory, and executive function) except for visual memory and resulted in more modulations in the working memory of UDD compared to BDD patients. More improvements in working memory were observed in responded patients and visual memory, age, and sex were determined as treatment response predictors. Working memory, visual memory, and age were identified as treatment response predictors in BDD and UDD patients, respectively. Conclusion: Bilateral rTMS improved cold cognition and depressive symptoms in UDD and BDD patients, possibly by altering cognitive control mechanisms (top-down), and processing negative emotional bias.

Clinical Predictors of Lung-Function Decline in Systemic-Sclerosis-Associated Interstitial Lung Disease Patients with Normal Spirometry.

Interstitial lung disease (ILD) is the leading cause of mortality in systemic sclerosis (SSc). Progressive pulmonary fibrosis (PPF) is defined as progression in 2 domains including clinical, radiological or lung-function parameters. Our aim was to assess predictors of functional decline in SSc-ILD patients and compare disease behavior to that in idiopathic pulmonary fibrosis (IPF) patients. Patients with normal forced vital capacity (FVC > 80% predicted; SSc-ILD: n = 31; IPF: n = 53) were followed for at least 1 year. Predictors of functional decline including clinical symptoms, comorbidities, lung-function values, high-resolution CT pattern, and treatment data were analyzed. SSc-ILD patents were significantly younger (59.8 ± 13.1) and more often women (93 %) than IPF patients. The median yearly FVC decline was similar in both groups (SSc-ILD = −67.5 and IPF = −65.3 mL/year). A total of 11 SSc-ILD patients met the PPF criteria for functional deterioration, presenting an FVC decline of −153.9 mL/year. Cough and pulmonary hypertension were significant prognostic factors for SSc-ILD functional progression. SSc-ILD patients with normal initial spirometry presenting with cough and PH are at higher risk for showing progressive functional decline.

Who to Refer to a Behavioral Insomnia Clinic? - Recommendations Based on Treatment Rationale and Response Prediction.

Purpose of Review: Response to cognitive-behavioral therapy for insomnia (CBT-I) is variable across individuals, and specialty insomnia clinics that provide CBT-I are few. To personalize insomnia treatments and maximize the cost-effectiveness of CBT-I, this paper reviews the conceptual model and content of CBT-I and the predictors of adherence/response to CBT-I as the basis for understanding who is most likely to benefit from CBT-I. Recent Findings: Specific patient-related attributes that predict benefit from CBT-I include (1) presence of maladaptive behaviors that serve as perpetuating factors of insomnia; (2) greater motivation to pursue therapy and higher treatment expectancies regarding CBT-I; (3) reduced use of hypnotics; (4) longer sleep duration; and (5) adequately treated psychiatric comorbidities. Summary: People presenting with chronic insomnia and these attributes may warrant prioritization in referral to behavioral insomnia clinics. Conversely, those who do not have such favorable characteristics may require interventions that address modifiable factors associated with poor adherence/response to CBT-I.

Predicting pathological response to chemoradiotherapy for rectal cancer: a systematic review.

Introduction: Pathological complete response (pCR) rates of approximately 20% following neoadjuvant long-course chemoradiotherapy for rectal cancer have given rise to non-operative or watch-and-wait (W&W) management. To improve outcomes there has been significant research into predictors of response. The goal is to optimize selection for W&W, avoid chemoradiotherapy in those who won't benefit and improve treatment to maximize the clinical complete response (cCR) rate and the number of patients who can be considered for W&W.Areas covered: A systematic review of articles published 2008-2018 and indexed in PubMed, Embase or Medline was performed to identify predictors of pathological response (including pCR and recognized tumor regression grades) to fluoropyrimidine-based chemoradiotherapy in patients who underwent total mesorectal excision for rectal cancer. Evidence for clinical, biomarker and radiological predictors is discussed as well as potential future directions.Expert opinion: Our current ability to predict the response to chemoradiotherapy for rectal cancer is very limited. cCR of 40% has been achieved with total neoadjuvant therapy. If neoadjuvant treatment for rectal cancer continues to improve it is possible that the treatment for rectal cancer may eventually parallel that of anal squamous cell carcinoma, with surgery reserved for the minority of patients who don't respond to chemoradiotherapy.

Effectiveness of antidepressants and predictors of treatment response for depressed HIV patients in Uganda.

Antidepressant medication is well established for the treatment of depression but little is known about its effectiveness for HIV populations in sub-Saharan Africa. This study examined the effectiveness of antidepressant treatment and predictors of treatment response among depressed HIV patients in Uganda. Data were obtained from two open-label trials in which 184 HIV patients were diagnosed with depression and started on antidepressants. Data at treatment baseline and month 6 were compared to assess treatment response, and baseline predictors of response were assessed. A total of 154 completed month 6, of whom 122 (79%) had responded to treatment and were no longer depressed (Patient Health Questionnaire-9, score < 5). Bivariate analysis found that education, CD4 count, general health functioning, physical health, pain, quality of life and social support variables were associated with antidepressant treatment response; however, only secondary education and social support independently predicted treatment response in logistic multiple regression analysis. Baseline depression severity was not associated with treatment response. In conclusion, antidepressants are effective in treating both moderate and more severe depression among persons living with HIV in Uganda, and education [OR (95% CI) = 4.33 (1.33-14.11)] and social support [OR (95% CI) = 1.54 (1.03-2.30)] were most predictive of treatment response.

Test-retest reliability of a new questionnaire for the retrospective assessment of long-term lithium use in bipolar disorder.

BACKGROUND: The identification of predictors of treatment response holds tremendous potential for the improvement of clinical outcomes in bipolar disorder (BP). The goal of this project is to evaluate the test-retest reliability of a new clinical tool, the Lithium Questionnaire (LQ), for the retrospective assessment of long-term lithium use in research participants with BP. METHODS: Twenty-nine individuals with BP-I (n=27), major depression (n=1), or schizoaffective disorder (n=1) were recruited for participation. The LQ was administered to all participants at two time-points, spaced 17 months apart on average, and used to determine each subject׳s score on the Retrospective Criteria of Long-Term Treatment Response in Research Subjects with Bipolar Disorder Scale, or the Alda Scale. Scores were confirmed through a best-estimate procedure, and test-retest reliability (intra-class correlation coefficient [ICC]) of the LQ was calculated. RESULTS: The correlation between the total Alda Scale scores at the two time-points was in the moderate range (ICC=0.60). Relevant clinical factors such as age or presence of Axis I psychiatric comorbidity did not influence the reliability. LIMITATIONS: The validity of the LQ was not examined. Inclusion of two participants with non-BP diagnoses may have affected the LQ׳s reliability, but re-analysis of our data after exclusion of these participants did not influence the reliability. The absence of measures of mood and cognition at time of LQ may be a limitation of this work. CONCLUSIONS: The LQ holds promise for the standardization of the retrospective assessment of long-term treatment in BP.
