Article Synopsis
  • The study examined joint effusion in patients with temporomandibular disorders (TMDs) that involved disc displacement, using MRI images of 97 temporomandibular joints (TMJs).
  • Of the TMJs evaluated, joint effusion was observed in 70 cases, primarily in the superior articular cavity, and the presence of myofascial or TMJ pain did not affect the occurrence of effusion.
  • The findings indicated that joint effusion is more prevalent in cases of disc displacement without reduction and that the volume of synovial fluid in effusions was unaffected by the presence of pain.

Article Synopsis
  • Hypercontractility and arrhythmia are significant issues in hypertrophic cardiomyopathy (HCM), and while beta-blockers are the standard treatment, they can lead to unwanted side effects like fatigue and lowered cardiac output.
  • Researchers screened 21 different beta-blockers and found that carvedilol, which is not commonly used for HCM, effectively reduces heart muscle contractility and arrhythmia through inhibition of the ryanodine receptor type 2 (RyR2) without dropping heart rate.
  • The study suggests that carvedilol’s unique properties, particularly its R-enantiomer, may offer a promising alternative treatment for HCM patients, combining antiarrhythmic effects and reduced contractility without compromising overall heart performance.

Hypertrophic cardiomyopathy (HCM) affects more than 1 in 500 people in the general population with an extensive burden of morbidity in the form of arrhythmia, heart failure, and sudden death. More than 25 years since the discovery of the genetic underpinnings of HCM, the field has unveiled significant insights into the primary effects of these genetic mutations, especially for the myosin heavy chain gene, which is one of the most commonly mutated genes. Our group has studied the molecular effects of HCM mutations on human β-cardiac myosin heavy chain using state-of-the-art biochemical and biophysical tools for the past 10 years, combining insights from clinical genetics and structural analyses of cardiac myosin.

Article Synopsis
  • Researchers conducted a genome-wide association study (GWAS) with 2,393 COVID-19 patients and 3,289 controls in Japan, identifying a specific genetic variant (rs60200309-A) on chromosome 5 linked to severe cases in individuals under 65.
  • The variant is more common in East Asians and associated with reduced expression of the DOCK2 gene, which was found to be lower in severe COVID-19 cases, particularly in non-classical monocytes.
  • Additionally, inhibiting DOCK2 in hamsters worsened pneumonia symptoms, indicating its potential as a biomarker and therapeutic target for severe COVID-19.

Acute heart failure (AHF) has become a global public health burden largely because of the associated high morbidity, mortality, and cost. The treatment options for AHF have remained relatively unchanged over the past decades. Historically, clinical congestion alone has been considered the main target for treatment of acute decompensation in patients with AHF; however, this is an oversimplification of the complex pathophysiology.
