Article Synopsis
  • High altitude (HA) can induce various illnesses like high altitude pulmonary edema (HAPE) in unacclimatized individuals, impacting their health significantly.
  • This study focuses on circulating cell free (cf) DNA as a biomarker for HAPE, finding higher cfDNA levels in HAPE patients compared to healthy controls and highlanders, which correlates with inflammation.
  • Additionally, elevated markers of cell death and oxidative DNA damage in HAPE patients suggest that cfDNA fragments might contribute to the inflammatory response and understanding HAPE's pathophysiology.

Article Synopsis
  • Pulmonary hypertension (PH) can occur in dogs as a complication of myxomatous mitral valve disease (MMVD), and this study focused on the role of the vasoactive substance endothelin-1 (ET-1) in this condition.
  • Lung and blood samples were taken from 20 client-owned dogs and analyzed for ET-1 and its receptor, with results revealing no significant differences in expression or concentration across various groups (normal, MMVD, and MMVD+PH).
  • The findings indicate that ET-1 might not play a key role in the development of PH due to MMVD in dogs, but the study's small sample size suggests that more research is necessary to validate these results.

Choledochal Cyst and Right Congenital Diaphragmatic Hernia: When to Intervene?

European J Pediatr Surg Rep

January 2024

Division of Pediatric Surgery, CHU Sainte-Justine, Montreal, Quebec, Canada.

Article Synopsis
  • Patients with congenital diaphragmatic hernia (CDH) may have other congenital issues, like choledochal cysts (CC), which complicate treatment; there's no clear agreement on when to surgically remove a CC.
  • Leaving a CC unrepaired can lead to serious complications such as biliary sludge and infections, while repairing it too early could cause problems with the CDH mesh used in previous surgeries.
  • A rare case is presented where a neonate with CDH developed a previously undetected CC, leading to surgery after severe complications, but ultimately, the patient recovered well and has normal liver function after 12 months.

Background: There is currently no effective treatment for the majority of patients with chronic obstructive pulmonary disease combined with pulmonary hypertension (COPD-PH). Numerous clinical trials have demonstrated the use of traditional Chinese medicine (TCM) herbal formulas in combination with routine western pharmacotherapy (WP) for the treatment of COPD-PH, with positive results. This meta-analysis was designed to evaluate the efficacy and safety of TCM herbal formulas in the treatment of COPD-PH.

The adult mammalian heart is known to have very limited regenerative capacity, explaining at least in part the frequency of cardiovascular diseases and their impact as the leading cause of death worldwide. By contrast, the neonatal heart has the ability to regenerate upon injury, and the molecular mechanisms underlying this regenerative capacity are intensely investigated to provide novel cues for the repair of the adult heart. However, the existing rodent neonatal injury models-apex resection, left anterior descending artery ligation and cryoinjury-have limitations, such as being technically demanding, yielding a nonphysiological injury type and/or lack of reproducibility.

Introduction: Although venous congestion secondary to elevated pulmonary artery pressure (PAP) has been hypothesized to worsen kidney function, the association of peak tricuspid regurgitation jet velocity (pTRV), a surrogate of PAP, with kidney outcomes remains uncertain in heart failure (HF) with preserved ejection fraction (HFpEF).

Methods: This analysis of the Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist (TOPCAT) trial analyzed participants with a left ventricular ejection fraction (LVEF) of ≥45% who had pTRV measured by echocardiography at baseline. For the cross-sectional analysis, the association of baseline pTRV with baseline estimated glomerular filtration rate (eGFR) was assessed using linear regression.

Int J Cardiol

January 2025

Department of Clinical Medicine, Aarhus University, Denmark; Department of Cardiology, Aarhus University Hospital, Denmark. Electronic address:

Article Synopsis
  • Chronic thromboembolic pulmonary hypertension (CTEPH) causes right ventricular dysfunction due to increased pressure in the lungs, and this study focuses on the relationship between RV to pulmonary artery coupling and invasive heart measurements.
  • A cohort of 139 CTEPH patients was studied, showing a significant correlation between the echocardiographic TAPSE/PASP ratio and pulmonary vascular resistance, with improvements in this ratio following treatments like BPA and PEA.
  • The findings suggest that the TAPSE/PASP ratio can be a useful tool for monitoring treatment outcomes in CTEPH patients, though further research is needed to determine its prognostic value and influence on treatment decisions.

Ortner's syndrome or cardiovocal syndrome is a rare condition referring to laryngeal recurrent nerve paralysis due to cardiovascular conditions. We report the case of a 66-year-old man, with a medical history of active smoking, who complained of hoarseness of voice secondary to vocal cord palsy. A neck and thoracic CT scan revealed severe enlargement of pulmonary main artery, which caused compression of the left recurrent laryngeal nerve in the aortopulmonary window The prolonged course of the left laryngeal nerve makes it susceptible to injury from cardiovascular structures in the mediastinum.

Myxomatous mitral valve disease (MMVD) stands out as the most prevalent acquired canine heart disease. Its occurrence can reach up to 40% in small breed dogs and escalates in geriatric canine populations. MMVD leads to thickening and incomplete coaptation of valve leaflets during systole, resulting in secondary mitral valve regurgitation.

  • Moyamoya syndrome (MMS) is linked to genetic disorders and arises from a mix of genetic mutations and modifiers, with a focus on whole-exome sequencing (WES) to identify these connections.
  • In a study of 13 patients, WES identified genetic conditions like neurofibromatosis type 1, Down syndrome, and others, confirming previously known modifier genes in some cases.
  • The research suggests that rare genetic variants associated with both MMS and conditions like pulmonary arterial hypertension could serve as new diagnostic tools and potential treatments in the future.
