Cervical cancer (CC) is one of the highest prevailing causes of female cancer-related mortality globally. A significant discrepancy in incidence has been noted between high and low-middle-income countries. The origins of CC have been accredited to the human papillomavirus (HPV) with serotypes 16 and 18 being the most prevalent.

Department of Pediatric Surgery and Urology, Robert-Debré University Hospital, Paris, France; Paris University, Paris, France; Université Paris Diderot-Sorbonne Paris Cité, Paris.

In pediatric thoracic surgery, reported predictors for increased risk are symptoms and active/previous infections (RAP). We investigated the adverse events related to Video-Assisted Thoracic Surgery (VATS) in pediatric patients when considering RAP predictors. A retrospective analysis of pediatric VATS major lung resections in 2008-2021 was conducted at three institutions.

Precision medicine, which among other aspects includes an individual's genomic data in diagnosis and management, has become the standard-of-care for Mendelian cardiovascular disease (CVD). However, early identification and management of asymptomatic patients with potentially lethal and manageable Mendelian CVD through screening, which is the promise of precision health, remains an unsolved challenge. The reduced costs of genomic sequencing have enabled the creation of biobanks containing in-depth genetic and health information, which have facilitated the understanding of genetic variation, penetrance, and expressivity, moving us closer to the genotype-first screening of asymptomatic individuals for Mendelian CVD.

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.

Article Synopsis
  • A study investigated whether stereotactic body radiotherapy (SBRT) is just as effective as standard radiotherapy for treating localized prostate cancer in terms of treatment failure rates.
  • The trial involved 874 men with early-stage prostate cancer, comparing SBRT (36.25 Gy in 5 sessions) to conventional radiotherapy (78 Gy in 39 sessions or 62 Gy in 20 sessions) over several weeks, focusing on the chance of being free from cancer progression after 5 years.
  • Results showed that SBRT was noninferior to standard treatment, with similar success rates in preventing cancer failure (95.8% for SBRT vs. 94.6% for control) but higher rates of genitour

Article Synopsis
  • Phagocytosis is a key immune function of white blood cells (leucocytes), but current models can't measure it in human tissues directly.
  • Researchers developed a new method using intradermal injection of methylene blue-labelled E. coli (MBEC) that allows for the measurement of this process in human skin.
  • The study showed that neutrophils and monocytes from inflamed tissue took up more MB than those in blood, demonstrating the model's potential for various research applications, including understanding phagocyte biology and infection risks in specific populations.

Awareness of strengths and weaknesses of cardiovascular magnetic resonance imaging: results from a questionnaire survey.

Eur Heart J Imaging Methods Pract

January 2024

Department of Cardiology, Deutsches Herzzentrum der Charité, Angiology and Intensive Care Medicine, Campus Virchow Klinikum, Augustenburger Platz 1, 13353 Berlin, Germany.

Article Synopsis
  • Extensive research has shown that cardiovascular magnetic resonance (CMR) is effective for diagnosing and monitoring cardiovascular diseases but is underused in clinical settings due to reimbursement issues.
  • A survey of 144 healthcare professionals revealed that while respondents recognized social impacts and some CMR benefits, significant gaps in knowledge about its full capabilities and advantages were present.
  • Despite these gaps, there was a positive attitude towards CMR, with many participants willing to travel and pay for the procedure, indicating a need for better awareness and educational strategies to enhance its use in healthcare.

Article Synopsis
  • Heart failure is increasingly challenging due to an ageing population, but mechanical circulatory support devices like ventricular assist devices and Extracorporeal Membrane Oxygenation (ECMO) are evolving to help manage this condition.
  • This review highlights how these devices function to relieve pressure on the heart and improve physiological measures such as stroke volume and intracardiac pressure, which begin to change immediately after device implantation.
  • While devices like Impella and TandemHeart have shown positive effects on heart function in patients with cardiogenic shock, more research is needed to evaluate their long-term clinical outcomes, and choosing the right device depends on individual patient circumstances.

Article Synopsis
  • The study addresses the challenge of accurately identifying and measuring aortic aneurysms, which is crucial but often limited by the time-consuming nature of high-resolution 3D CMR sequences used for assessment.
  • Researchers developed a 3D U-Net that can create detailed 3D segmentations of the aorta from standard 2D images with lower resolution, enhancing the efficiency of aortic assessments in clinical and population studies.
  • The results showed that the new U-Net model produced 93% clinically suitable segmentations and achieved a high DICE score of 0.9, matching the accuracy of traditional high-resolution methods, indicating its potential for reliable clinical use.

Article Synopsis
  • Cerebrovascular events (CVEs) can happen during or after a procedure called TAVR, which replaces a heart valve, and can lead to serious health problems.
  • Even though strokes have become less common since TAVR started, they’re still a major concern because TAVR is being used more often.
  • New devices and treatments are being tested to help prevent CVEs, but current options may not reduce stroke risk enough, and there are concerns about bleeding from the medication used.

Importance: The emergence of novel programming guidelines that reduce premature and inappropriate therapies along with the availability of new implantable cardioverter-defibrillator (ICD) technologies lacking traditional endocardial antitachycardia pacing (ATP) capabilities requires the reevaluation of ATP as a first strategy in terminating fast ventricular tachycardias (VTs) in primary prevention ICD recipients.

Objective: To assess the role of ATP in terminating fast VTs in primary prevention ICD recipients with contemporary programming.

Design, Setting, And Participants: This global, prospective, double-blind, randomized clinical trial had an equivalence design with a relative margin of 35%.

Background: In order to identify candidacy and treatment response for patients with obstructive hypertrophic cardiomyopathy (oHCM), clinicians need an accurate means of assessing symptoms, function, and quality of life. While the New York Heart Association (NYHA) Classification is most often used for this purpose, the Kansas City Cardiomyopathy Questionnaire (KCCQ-23) is more accurate and sensitive to change, although less familiar to practicing clinicians. To support interpreting the KCCQ-23, we describe cross-sectional and longitudinal changes in KCCQ scores in the context of the NYHA.

An overview of immune checkpoint inhibitor toxicities in bladder cancer.

Toxicol Rep

December 2024

Department of Medical Oncology, Medway NHS Foundation Trust, Windmill Road, Gillingham ME7 5NY, UK.

Bladder cancer is the tenth most prevalent malignancy worldwide, with a significant mortality burden. Urothelial carcinoma (UC) is the most common histological subtype, and treatment options are guided by whether the disease is muscle-invasive (MIBC) or non-muscle-invasive (NMIBC), with subsequent risk group stratification. The growing popularity of immune checkpoint inhibitors (ICIs) to treat MIBC and NMIBC as either monotherapy or combined with intravesical agents, may radically change the treatment paradigm of UC.
