Economic evaluations conducted to inform healthcare resource allocation often rely on quality-adjusted life years (QALYs) to measure therapeutic benefit. However, QALYs, with underlying health utilities estimated using the EQ-5D or SF-36, may fail to capture the impact of disease for all patients. How well-being and heath utility differ across several common conditions was explored. ⋯ Differences in rankings of disease severity by metric indicate that the results of cost-utility analyses might be biased against treatments for certain diseases. As patient preferences for clinical outcomes vary, the full burden of disease should be considered in evaluations. Restricting access to treatments based on an incomplete estimate of burden could lead to misallocation of resources and a withholding of therapies that patients find valuable.

The SPUR (Social, Psychological, Usage, and Rational) Adherence Profiling Tool is a recently developed adaptive instrument for measuring key patient-level risk factors for adherence problems. This study describes the SPUR questionnaire's psychometric refinement and evaluation. ⋯ The SPUR tool represents a promising new adaptive instrument for measuring adherence accurately and efficiently using the digital behavioral diagnostic tool.

Meta Analysis
Conducting and critically appraising a high-quality systematic review and meta-analysis pertaining to COVID-19.
With constantly emerging new information regarding the epidemiology, pathogenesis, diagnosis and management of Coronavirus Disease 2019 (COVID-19), reviewing literature related to it has become increasingly complicated and resource-intensive. In the setting of this global pandemic, clinical decisions are being guided by the results of multiple pertinent studies; however, it has been observed that these studies are often heterogenous in design and population characteristics and results of initial trials may not be replicated in subsequent studies. The resulting clinical conundrum can be resolved by high-quality systematic review and meta-analysis with a robust and reliable methodology, encapsulating and critically appraising all the available literature relevant to the clinical scenario under scrutiny. ⋯ It can identify optimal diagnostic algorithms, assess efficacy of treatment strategies, and analyze inherent factors influencing the efficacy of treatment for COVID-19. The current review aims to provide a basic guide to plan and conduct a high-quality systematic review and meta-analysis pertaining to COVID-19, describing the main steps and addressing the pitfalls commonly encountered at each step. Knowledge of the basic steps would also allow the reader to critically appraise published systematic review and meta-analysis and the quality of evidence provided therein.

Intradiscal vacuum phenomenon (IVP) is the collection of gas within the intervertebral discs. It has been reported with various spinal disorders. The exact role of IVP in spinal degeneration leading to low back pain (LBP) is unclear. We aimed to obtain the prevalence of IVP in patients with LBP. Our second aim was to understand whether IVP was associated with intervertebral disc degeneration (IVDD), Modic changes, and subchondral sclerosis (SS). ⋯ Intradiscal vacuum phenomenon was closely associated with severe IVDD, Modic changes, and SS. Further prospective clinical and laboratory studies are necessary to better delineate the pathogenesis of IVP.

This study evaluated body mass index (BMI) and weight changes in people living with human immunodeficiency virus (HIV-1; PLWH) initiated on single-tablet darunavir/cobicistat/emtricitabine/tenofovir alafenamide (DRV/c/FTC/TAF) or bictegravir/FTC/TAF (BIC/FTC/TAF). ⋯ BIC/FTC/TAF was associated with greater BMI and weight increases compared to DRV/c/FTC/TAF. Weight gain and its sequelae may add to the clinical burden of PLWH and should be considered among other factors when selecting antiretroviral single-tablet regimens.
