Seven prospective real-world studies conducted in general practices in Belgium of antihypertensive treatment with valsartan-centric regimens were pooled to examine similarities and differences in determinants of blood pressure (BP) values (mmHg) and BP control rates between female and male patients. ⋯ Valsartan-centric treatment regimens are associated with significant reductions in BP level and improvement in BP control in both women and men. The determinants revealed in modeling provide guidance to clinicians in the common and differential management of hypertension in female and male patients.

Content validation is essential in the development of patient-reported instruments to ensure relevancy and understandability. The aim was to evaluate patient understanding of the Prescription Opioid Misuse and Abuse Questionnaire (POMAQ) using cognitive interviewing among adults with chronic moderate to severe pain. ⋯ The POMAQ demonstrated content validity among patients with moderate to severe chronic pain and is undergoing psychometric evaluation among a larger cohort of patients.

Observational Study
Treatment sequencing for the care of patients with advanced or metastatic non-small cell lung cancer in the United States.
Therapeutic advances for the treatment of patients with advanced/metastatic non-small cell lung cancer (NSCLC) have led to additional options for care. This observational study was designed to describe emerging treatment patterns and survival outcomes. ⋯ There is heterogeneity in sequencing strategies that limit the ability to conduct robust comparative effectiveness research of treatment sequences. Since few patients follow a similar treatment trajectory, comparative effectiveness research will be challenged to identify treatment sequences with sufficient sample size.

Adenylosuccinic acid (ASA) modifies Duchenne muscular dystrophy (DMD) progression in dystrophic mdx mice and human DMD patients. Despite an established role for ASA in augmenting metabolism and cellular energy homeostasis, our previous data suggests an undiscovered ulterior mode of action capable of modifying DMD disease course. Here, we identify ASA as a novel inducer of nuclear factor erythroid 2-related factor-2 (Nrf2), master regulator of the antioxidant and cytoprotective response to cell stress.

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.
