In December 2019, the first COVID-19 case, caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) was reported in Wuhan, China. The SARS-CoV-2 rapidly disseminated throughout the world via community spread, acquiring pandemic status with significant fatality. ⋯ Thus, nucleic acid and antibody dependent tests complement each other in identifying human SARS-CoV-2 infection and shaping up subsequent immunological responses. This article discusses the complimentary association of nucleic acid identification (corresponding to an active infection) and antibody testing (the yester CoV-2 infection vulnerability) as the diagnostic and screening measures of SARS-CoV-2 infection. Highlights Nucleic acid (RNA) identification and specific antibody detection against SARS-CoV-2 are the noted diagnostic mechanisms for screening human SARS-CoV-2 infection. While nucleic acid identification screens prevailing SARS-CoV-2 infection, detection of SARS-CoV-2 specific antibodies signifies a past infection, even in asymptomatic subjects. Antibodies against SARS-CoV-2 provide a potential therapeutic option via transfer from antibody rich plasma of a recovered subject to an infected individual. Nucleic acid identification may not absolutely confirm the infection because of frequent SARS-CoV-2 genome mutations and possible technical errors, while specific antibody detection also needs at least (8-14) days for detectable screening of B-cell generated antibodies. Nucleic acid and antibody tests are complementary to each other as an early stage diagnostic assay for SARS-CoV-2 infection and possible therapy (antibodies). Sufferers with a high clinical suspicion but negative RT-PCR screening could be examined via combined imaging and repeated swab test.

Randomized Controlled Trial
Safety and efficacy of a prescription digital therapeutic as an adjunct to buprenorphine for treatment of opioid use disorder.
To evaluate the safety and efficacy of a digital therapeutic in treatment-seeking individuals with opioid use disorder (OUD) in an analysis of randomized clinical trial (RCT) data (ClinicalTrials.gov identifier: NCT00929253). ⋯ A prescription digital therapeutic (PDT) in combination with buprenorphine therapy improves clinically significant patient outcomes including abstinence from illicit opioids and retention in treatment compared with treatment as usual.

Randomized Controlled Trial Observational Study
Real-world evidence for a prescription digital therapeutic to treat opioid use disorder.
To evaluate patient engagement and usage of a prescription digital therapeutic (PDT) and associated outcomes of opioid use and treatment retention in a large real-world dataset of patients with opioid use disorder (OUD) treated with buprenorphine medication for opioid use disorder (MOUD). PDTs are software-based disease treatments evaluated for safety and effectiveness in randomized clinical trials (RCTs), and authorized by the U.S. Food and Drug Administration (FDA) to treat disease with approved directions for use (label). ⋯ Results demonstrate that reSET-O is readily and broadly used by patients with OUD and that high real-world engagement with the therapeutic is positively associated with abstinence and retention in treatment. ReSET-O is a potentially valuable adjunct to buprenorphine MOUD therapy for patients with OUD.

Multicenter Study Observational Study
An international multicenter observational non-interventional prospective study of the efficacy of azilsartan medoxomil in overweight or obese patients with arterial hypertension (CONSTANT).
Control of arterial hypertension in obese or overweight patients is complicated since obesity directly contributes to increased blood pressure, requiring new, highly effective antihypertensive drugs. This study evaluates the efficacy of azilsartan medoxomil in real clinical practice. ⋯ Over the study time of 1945 patients, significant changes in blood pressure levels over time were noted, and a high frequency of response to the azilsartan therapy was observed. Adverse events related to the study drug were of mild or moderate intensity and did not require discontinuation of therapy. Thus, azilsartan medoxomil demonstrated a good safety profile and provided effective blood pressure control for overweight or obese patients with hypertension in real clinical practice.

Major depressive disorder (MDD) is a globally prevalent chronic psychiatric illness with a significant disease impact. As many as 30% of patients with MDD do not adequately respond to two therapies and are considered to be treatment resistant. This study aimed to quantify healthcare costs associated with treatment resistant depression (TRD) in the UK. ⋯ The results suggest that antidepressant treatments for TRD that are more effective in reducing the time spent in an MDE health state, and helping patients achieve remission and recovery, are essential for reducing the overall HCRU and costs in patients with TRD. Cost of TRD in the UK Strengths and limitations of this study This observational study of TRD is the first to assess the HCRU impact associated with different predefined health states. Using retrospective data from both primary and secondary care physicians from regions across the UK ensures a representative real-world patient population. One limitation is that the selection of patients is based on criteria that define TRD that rely on physician judgement. Although the study captures direct HCRU costs, the indirect costs of lost productivity and care are not included in the overall burden. This study has defined the current clinical management of patients with TRD in the UK and provides an estimate of the associated HCRU and associated costs.
