Abstract

Since the stepped care approach has been widened to four classes of antihypertensive drugs, demographic considerations enter into the choice of the first line drug. Calcium antagonists have been claimed to be more active in older patients because the average BP decrease after dose titration could be greater in this age group than in younger people. In this study, the response to a fixed dose of diltiazem has been related to different demographic factors. The selected patients have been treated with diltiazem 120 mg b.i.d. in monotherapy for at least 14 days irrespective of their response to a lower dose. There were 231 patients (115 M, 116 F). Their average age was 59 +/- 11 years (24 to 82) and their treatment duration was 44 +/- 27 days. Diltiazem lowered BP from 171 +/- 1/103 +/- 7 mmHg to 156 +/- 1/91 +/- 1 mmHg. The decline in both SBP and DBP with diltiazem was significantly related to their control values (r = 0.31 and 0.28 respectively, p less than 0.0001 for both). Although control SBP was related to age (r = 0.40, p less than 0.0001), its decrease with diltiazem was not. Neither control DBP nor its decrease with diltiazem were related to age. Although the average SBP was higher in patients over 60 years than in younge...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
