Comparing quality of life and postoperative pain after limited access and conventional aortic valve replacement: design and rationale of the LImited access aortic valve replacement (LIAR) trial

Background: Surgical aortic valve replacement (SAVR) via limited access approaches ('mini-AVR') have proven to be safe alternative for the surgical treatment of aortic valve disease. However, it remains unclear whether these less invasive approaches are associated with improved quality of life and/or reduced postoperative pain when compared to conventional SAVR via full median sternotomy (FMS).Study design: The LImited access Aortic valve Replacement (LIAR) trial is a single-center, single blind randomized controlled clinical trial comparing 2 arms of 80 patients undergoing limited access SAVR via J-shaped upper hemi-sternotomy (UHS) or conventional SAVR through FMS. In all randomized patients, the diseased native aortic valve is planned to be replaced with a rapid deployment stented bioprosthesis. Patients unwilling or unable to participate in the randomized trial will be treated conventionally via SAVR via FMS and with implantation of a sutured valve prosthesis. These patients will participate in a prospective registry.Study methods: Primary outcome is improvement in cardiac-specific quality of life, measured by two domains of the Kansas City Cardiomyopathy Questionnaire up to one year after surgery. Secondary outcomes include, but are not limited to: generic quality of life measured with the Short Form-36, postoperative pain, perioperative (technical success rate, operating time) and postoperative outcomes (30-day and one-year mortality), complication rate and hospital length of stay.Conclusion: The LIAR trial is designed to determine whether a limited access approach for SAVR ("mini-AVR") is associated with improved quality of life and/or reduced postoperative pain compared with conventional SAVR through FMS

Self-reported adherence and pharmacy refill adherence are both predictive for an undetectable viral load among HIV-infected migrants receiving cART

HIV-infected migrants were shown to have poorer treatment outcomes than Dutch HIV-infected patients, often due to worse treatment adherence. Self-reported adherence would be an easy way to monitor adherence, but its validity relative to pharmacy refill adherence has not been extensively evaluated in migrants. All HIV-infected migrants older than 18 years and in care at the two Rotterdam HIV-treatment centers were eligible. Refill data with leftover medication (PRL) (residual pill count) were obtained from their pharmacies up to 15 months prior to inclusion. Self-reported adherence to combination Antiretroviral Therapy was assessed by four questions about adherence at inclusion. Additionally, risk factors for pharmacy refill non-adherence were examined. In total, 299 HIV-infected migrants were included. Viral load (VL) was detectable in 11% of the patients. Specificity of PRL was 53% for patients with an adherence of 100% and decreased with lower cut-off values. Sensitivity and negative predictive value (NPV) were 68% and 15% and increased with lower cut-off values. Positive predictive value (PPV) was around 93% for all cut-off values. Using the self-reported questions, 139 patients (47%) reported to be adherent. Sensitivity was 49% and specificity was 72%. PPV and NPV were 95% and 13%. No risk factors for pharmacy refill non-adherence were found in multivariable analyses. Both PRL and self-reported adherence, can predict undetectable VL in HIV-infected migrants. PPV and NPV are similar for both methods. This study shows that using four self-reported items is sufficient to predict adherence which is crucial for optimal clinical outcome in HIV-infected migrants

Health-related quality of life among persons with initial mild, moderate, and severe or critical COVID-19 at 1 and 12 months after infection: a prospective cohort study

BACKGROUND: Currently, there is limited evidence about the long-term impact on physical, social and emotional functioning, i.e. health-related quality of life (HRQL) after mild or moderate COVID-19 not requiring hospitalization. We compared HRQL among persons with initial mild, moderate or severe/critical COVID-19 at 1 and 12 months following illness onset with Dutch population norms and investigated the impact of restrictive public health control measures on HRQL. METHODS: RECoVERED, a prospective cohort study in Amsterdam, the Netherlands, enrolled adult participants after confirmed SARS-CoV-2 diagnosis. HRQL was assessed with the Medical Outcomes Study Short Form 36-item health survey (SF-36). SF-36 scores were converted to standard scores based on an age- and sex-matched representative reference sample of the Dutch population. Differences in HRQL over time were compared among persons with initial mild, moderate or severe/critical COVID-19 using mixed linear models adjusted for potential confounders. RESULTS: By December 2021, 349 persons were enrolled of whom 269 completed at least one SF-36 form (77%). One month after illness onset, HRQL was significantly below population norms on all SF-36 domains except general health and bodily pain among persons with mild COVID-19. After 12 months, persons with mild COVID-19 had HRQL within population norms, whereas persons with moderate or severe/critical COVID-19 had HRQL below population norms on more than half of the SF-36 domains. Dutch-origin participants had significantly better HRQL than participants with a migration background. Participants with three or more COVID-19 high-risk comorbidities had worse HRQL than part participants with fewer comorbidities. Participants who completed the SF-36 when restrictive public health control measures applied reported less limitations in social and physical functioning and less impaired mental health than participants who completed the SF-36 when no restrictive measures applied. CONCLUSIONS: Twelve months after illness onset, persons with initial mild COVID-19 had HRQL within population norms, whereas persons with initial moderate or severe/critical COVID-19 still had impaired HRQL. Having a migration background and a higher number of COVID-19 high-risk comorbidities were associated with worse HRQL. Interestingly, HRQL was less impaired during periods when restrictive public health control measures were in place compared to periods without.

Risk factors for non-adherence to cART in immigrants with HIV living in the Netherlands: Results from the Rotterdam ADherence (ROAD) project

In the Netherlands, immigrant people living with HIV (PLWH) have poorer psychological and treatment outcomes than Dutch PLWH. This cross-sectional field study examined risk factors for non-adherence to combination Antiretroviral Therapy (cART) among immigrant PLWH. First and second generation immigrant PLWH attending outpatient clinics at two HIV-treatment centers in Rotterdam were selected for this study. Socio-demographic and clinical characteristics for all eligible participants were collected from an existing database. Trained interviewers subsequently completed questionnaires together with consenting participants (n = 352) to gather additional data on socio-demographic characteristics, psychosocial variables, and self-reported adherence to cART. Univariable and multivariable logistic regression analyses were conducted among 301 participants who had used cART 6 months prior to inclusion. Independent risk factors for self-reported non-adherence were (I) not having attended formal education or only primary school (OR = 3.25; 95%CI: 1.28-8.26, versus University), (II) experiencing low levels of social support (OR = 2.56; 95%CI: 1.37-4.82), and (III) reporting low treatment adherence self-efficacy (OR = 2.99; 95%CI: 1.59-5.64). Additionally, HIV-RNA >50 copies/ml and internalized HIV-related stigma were marginally associated (P<0.10) with non-adherence (OR = 2.53; 95%CI: 0.91-7.06 and OR = 1.82; 95%CI: 0.97-3.43). The findings that low educational attainment, lack of social support, and low treatment adherence self-efficacy are associated with non-adherence point to the need for tailored supportive interventions. Establishing contact with peer immigrant PLWH who serve as role models might be a successful intervention for this specific population

Response shift after coronary revascularization

Purpose The aims of this study were to investigate (1) the extent to which response shift occurs among patients with coronary artery disease (CAD) after coronary revascularization, (2) whether the assessment of changes in health-related quality of life (HRQoL), controlled for response shift, yield more valid estimates of changes in HRQoL, as indicated by stronger associations with criterion measures of change, than without controlling for response shift, and (3) if occurrences of response shift are related to patient characteristics. Methods Patients with CAD completed the SF-36 and the Seattle Angina Questionnaire (SAQ7) at baseline and 3 months after coronary revascularization. Sociodemographic, clinical and psychosocial variables were measured with the patient version of the New York Heart Association-class, Subjective Significance Questionnaire, Reconstruction of Life Events Questionnaire (RE-LIFE), and HEXACO personality inventory. Oort's Structural Equation Modeling (SEM) approach was used to investigate response shift. Results 191 patient completed questionnaires at baseline and at 3 months after treatment. The SF-36 showed recalibration and reprioritization response shift and the SAQ7 reconceptualization response shift. Controlling for these response shift effects did not result in more valid estimates of change. One significant association was found between reprioritization response shift and complete integration of having CAD into their life story, as indicated by the RE-LIFE. Conclusion Results indicate response shift in HRQoL following coronary revascularization. While we did not find an impact of response shift on the estimates of change, the SEM approach provides a more comprehensive insight into the different types of change in HRQoL following coronary revascularization.Biological, physical and clinical aspects of cancer treatment with ionising radiatio

Carotid Intima-Media Thickness Progression as Surrogate Marker for Cardiovascular Risk Meta-Analysis of 119 Clinical Trials Involving 100 667 Patients

Background: To quantify the association between effects of interventions on carotid intima-media thickness (cIMT) progression and their effects on cardiovascular disease (CVD) risk. Methods: We systematically collated data from randomized, controlled trials. cIMT was assessed as the mean value at the common-carotid-artery; if unavailable, the maximum value at the common-carotid-artery or other cIMT measures were used. The primary outcome was a combined CVD end point defined as myocardial infarction, stroke, revascularization procedures, or fatal CVD. We estimated intervention effects on cIMT progression and incident CVD for each trial, before relating the 2 using a Bayesian meta-regression approach. Results: We analyzed data of 119 randomized, controlled trials involving 100 667 patients (mean age 62 years, 42% female). Over an average follow-up of 3.7 years, 12 038 patients developed the combined CVD end point. Across all interventions, each 10 μm/y reduction of cIMT progression resulted in a relative risk for CVD of 0.91 (95% Credible Interval, 0.87–0.94), with an additional relative risk for CVD of 0.92 (0.87–0.97) being achieved independent of cIMT progression. Taken together, we estimated that interventions reducing cIMT progression by 10, 20, 30, or 40 μm/y would yield relative risks of 0.84 (0.75–0.93), 0.76 (0.67–0.85), 0.69 (0.59–0.79), or 0.63 (0.52–0.74), respectively. Results were similar when grouping trials by type of intervention, time of conduct, time to ultrasound follow-up, availability of individual-participant data, primary versus secondary prevention trials, type of cIMT measurement, and proportion of female patients. Conclusions: The extent of intervention effects on cIMT progression predicted the degree of CVD risk reduction. This provides a missing link supporting the usefulness of cIMT progression as a surrogate marker for CVD risk in clinical trials

Are retrospective measures of change in quality of life more valid than prospective measures?

Contains fulltext : 178670.pdf (publisher's version ) (Closed access)Background: Adaptation to changing health presents a challenge to measuring change in quality of life (QoL). Previous studies have shown that different methods for measuring change yield different results, but it is unclear which method provides a more valid measurement of change. We investigated which of 3 commonly used methods for measuring change in QoL yielded the strongest associations with clinical measures of change in health status. Methods: A total of 268 human immunodeficiency virus (HIV)-1-infected patients starting highly active antiretroviral therapy completed QoL measures at baseline and after 36 weeks. We calculated Pearson correlation coefficients between change in QoL according to a prospective baseline and prospective follow-up measurement, a retrospective baseline and prospective follow-up measurement, or retrospective transition questions and change in CD4-cell count, plasma viral-load, body mass index, and hemoglobin concentration. Results: Patients evaluated their QoL significantly worse on the retrospective than on the prospective baseline measurement (P < 0.01). These results may indicate that patients' reference value by which they evaluate their QoL changed over time, which would invalidate prospective serial QoL measurements. The retrospective baseline measurement method yielded strongest associations with clinical measures of change (P = 0.02 to P < 0.01). Distinguishing between the change inferred from the conventional prospective and the retrospective baseline measurement method was meaningful because the prospective method did not lead to changes that would be considered clinically significant, whereas the retrospective baseline measurement method did. Conclusions: A method for measuring change in QoL incorporating a retrospective baseline-measurement showed strongest associations with change in clinical indicators of health status, suggesting a more valid measurement of change in QoL than a conventional prospective method
