Background: Despite tremendous therapeutic advancements, a significant proportion of coronary artery disease patients suffer from refractory angina pectoris, that is, quality-of-life-compromising angina that is non-manageable with established pharmacological and interventional treatment options. Adenoviral vascular endothelial growth factor-D (AdVEGF-D)-encoding gene therapy (GT) holds promise for the treatment of refractory angina.

Methods: ReGenHeart is an investigator-initiated, multicentre, randomised, placebo-controlled and double-blinded phase 2 clinical trial that aims to study the safety and efficacy of intramyocardially administered angiogenic AdVEGF-D GT for refractory angina.

Genome-wide studies define new genetic mechanisms of IgA vasculitis.

medRxiv

October 2024

Department of Medicine, Division of Nephrology, Columbia University, College of Physicians & Surgeons, New York, NY, USA.

Article Synopsis
  • IgA vasculitis (IgAV) is a pediatric disease characterized by skin and systemic symptoms, and researchers conducted comprehensive studies involving genome, transcriptome, and proteome analyses on a large cohort of IgAV patients and controls to better understand the disease mechanisms.* -
  • Significant associations were found with specific genetic risk factors, including two novel non-HLA loci linked to IgA receptor functioning, which may contribute to disease development through altered immune responses.* -
  • Systems biology approaches helped identify key regulatory networks and master regulators in myeloid cells, along with 21 genetic loci that overlap with IgA nephropathy, suggesting shared pathways in these related conditions.*

Debates concerning the reliability and validity of operationalized criteria and diagnostic tools have surrounded the issue of schizophrenia diagnosis and clinical decision-making related to the disorder. The notion of the praecox feeling (PF) has played a prominent role in the discussions as an example of the possibility of a rapid and potentially valid diagnosis based solely on "intuition" or a peculiar emotional experience or impression arising in a physician during an interaction with a patient with schizophrenia. In this paper, we argue that PF is enabled by the (phenomenologically understood) intercorporeal dimension of the clinical encounter.

Article Synopsis
  • The study investigates the use of different grades of hydrogenated phospholipids (HPL) as excipients in solid dispersions for the drug fenofibrate (FEN), showing that both binary and ternary blends can enhance the drug's solubility.
  • X-ray diffraction analysis confirmed that ternary blends achieved complete conversion of crystalline FEN to an amorphous state, leading to better drug release compared to binary blends and marketed formulations.
  • Results indicated that the formulations containing higher levels of phosphatidylcholine demonstrated improved drug permeation, suggesting that HPL blends created via hot melt extrusion could be a promising option for formulating poorly water-soluble drugs like FEN.

Obesity-related drug transporter expression alterations in human liver and kidneys.

Pharmacol Rep

December 2024

Department of Pharmaceutics, Ernest Mario School of Pharmacy, Rutgers, The State University of New Jersey, 160 Frelinghuysen Road, Piscataway, NJ, 08854, USA.

Article Synopsis
  • Obesity can significantly alter how the body processes drugs, particularly affecting the liver and kidneys which are key to drug clearance and absorption.
  • A study compared gene expression of drug transporters in liver and kidney tissues between lean and overweight/obese individuals, finding that certain transporters were either up-regulated or down-regulated in obese subjects.
  • These changes in transporter gene expression could influence drug pharmacokinetics in obese individuals, requiring more research to better understand the impact on medication dosing and effectiveness.

Article Synopsis
  • Modular, uncemented conical stems are a viable option for revisions in total hip arthroplasty (THA) for patients with loss of proximal bone stock, but the use of extended trochanteric osteotomy (ETO) during extraction can lead to significant complications, such as blood loss and infections.
  • A study comparing outcomes between patients who underwent THA revisions with and without ETO found that while pre-operative scores were lower in the ETO group, post-operative functional outcomes did not significantly differ, although the no-ETO group showed better quality of life scores.
  • The findings suggest that ETO may not negatively impact revision outcomes, but given its invasive nature, it should be approached on a case-by-case basis.

Barriers to Type 1 Diabetes Adherence in Adolescents.

J Clin Med

September 2024

Department of Pediatric Diabetes, Clinical Auxology and Obesity, Poznan University of Medical Sciences, Szpitalna Street 27/33, 60-572 Poznan, Poland.

Adolescence is a particularly crucial period of physical, emotional, and social development and adaptation, rendering these formative years rather challenging for individuals with chronic conditions like type 1 diabetes (T1D). Despite rapid improvement in diabetes therapies, adolescents with T1D are characterized by poorer adherence to treatment regimens compared with other pediatric age groups. Insufficient adherence is strongly related to low diabetes control, increasing morbidity, and risk for premature mortality.

Deep eutectic solvents (DESs) have attracted attention from researchers as novel compounds for extracting active substances because of their negligible toxicity, polarity, and ability to be tailored depending on the experiment. In this review, we discuss deep eutectic solvents as a promising medium for the extraction of adaptogenic compounds. In comparison to traditional methods, extraction with the use of DESs is a great alternative to the excessive usage of harmful organic solvents.

Over the past few years, numerous bacterial strains have become resistant to selected drugs from various therapeutic groups. A potential tool in the fight against these strains is antimicrobial photodynamic therapy (APDT). APDT acts in a non-specific manner by generating reactive oxygen species and radicals, thereby inducing multidimensional intracellular effects.
