Polypharmacy-related drug-drug interactions (DDIs) are a significant and growing healthcare concern. An increasing number of therapeutic drugs on the market underscores the necessity to accurately assess new drug combinations during pre-clinical evaluation for DDIs. primary human hepatocytes (PHH) models are only applicable for short term induction studies due to their rapid loss of metabolic function.

Global recommendations on adhesion prophylaxis in gynaecological laparoscopic surgery.

Adhesions are recognised as one of the most common complications of abdominal surgery; their diagnosis and prevention remains a significant unmet need in surgical therapy, affecting negatively a patient's quality of life and healthcare budgets. In addition, postoperative pelvic adhesions pose a high risk of reduced fertility in women of childbearing age. These 2023 Global Recommendations on Adhesion Prevention in Gynaecological Laparoscopic Surgery provide agreed-upon statements to guide clinical practice, with the ultimate goal of improving patient outcomes.

A Single-Centre Experience of the Management of Infective Endocarditis.

Background: Treatment for infective endocarditis (IE) is usually medical, with surgery reserved for those failing medical management or developing complications. Currently, 25%-50% of patients undergo surgery for IE with a 70%-80% immediate survival rate. However, there is controversy over the timing of surgery following cerebrovascular events, which occur in 15%-30% of IE patients.

Utilization of a Human Liver Tissue Chip for Drug-Metabolizing Enzyme Induction Studies of Perpetrator and Victim Drugs.

Polypharmacy-related drug-drug interactions (DDIs) are a significant and growing healthcare concern. Increasing number of therapeutic drugs on the market underscores the necessity to accurately assess the new drug combinations during pre-clinical evaluation for DDIs. primary human hepatocyte (PHH)-only models are commonly used only for perpetrator DDI studies due to their rapid loss of metabolic function.

Surgery for Active Infective Endocarditis on Mitral Valve: Anatomical, Surgical, and Disease Factors as Long-Term Outcome Modifiers.

: Determinants of long-term outcomes after surgery for native mitral valve endocarditis have not been thoroughly investigated. The aim of this study was to assess anatomical, disease, and surgical risk factors for long-term mortality and need of reintervention, in patients undergoing mitral valve surgery for active endocarditis. : Patients who underwent surgery for active native mitral valve endocarditis at three academic centres, between 2000 and 2022, were analysed.

Role of serial F-fludeoxyglucose positron emission tomography in determining the therapeutic efficacy of immunosuppression and clinical outcome in patients with cardiac sarcoidosis.

Background: Myocardial inflammation and perfusion defects detected by F-fludeoxyglucose (FDG) and Rubidium-82 positron emission tomography (PET) may be associated with ventricular arrhythmias (VAs) in cardiac sarcoidosis (CS). The role of serial quantitative PET in determining the effect of treatment on myocardial inflammation and clinical outcomes is yet to be defined.

Methods: Newly diagnosed CS patients with active myocardial inflammation (maximum standardised uptake value (SUVmax) ≥ 2.

Surgical repair and replacement for native mitral valve infective endocarditis.

Aims: The clinical benefits of mitral valve repair over replacement in the setting of mitral infective endocarditis are not clearly established.

Methods: Data of patients who underwent cardiac surgery for infective endocarditis over a 20-year period (2001-2021) at two cardiac centres were reviewed. Among them, 282 patients underwent native mitral valve surgery and were included in the study.

A Novel Milli-fluidic Liver Tissue Chip with Continuous Recirculation for Predictive Pharmacokinetics Applications.

A crucial step in lead selection during drug development is accurate estimation and optimization of hepatic clearance using in vitro methods. However, current methods are limited by factors such as lack of physiological relevance, short culture/incubation times that are not consistent with drug exposure patterns in patients, use of drug absorbing materials, and evaporation during long-term incubation. To address these technological needs, we developed a novel milli-fluidic human liver tissue chip (LTC) that was designed with continuous media recirculation and optimized for hepatic cultures using human primary hepatocytes.

Redo aortic valve replacement valve-in-valve trans-catheter aortic valve implantation: a UK propensity-matched analysis.

This study sought to compare the morbidity and mortality of redo aortic valve replacement (redo-AVR) versus valve-in-valve trans-catheter aortic valve implantation (valve-in-valve TAVI) for patients with a failing bioprosthetic valve. A multicenter UK retrospective study of redo-AVR or valve-in-valve TAVI for patients referred for redo aortic valve intervention due to a degenerated aortic bioprosthesis. Propensity score matching was performed for confounding factors.

Rare Metallic Allergy Reaction Presentation to Cholecystectomy Surgical Clip.

Metal allergies have been a growing concern in the general population over the past several decades. Laparoscopic cholecystectomy is the standard treatment for gallbladder diseases such as cholelithiasis and cholecystitis, during which surgical clips composed of metals such as nickel or titanium are often used to clamp the arteries and ducts. These metals are documented to produce hypersensitivity reactions.

Associations Between Diurnal Timing of Spinal Cord Injury and Its Etiology and Co-Morbidities.

Circadian rhythms play a role in time-of-day differences in risk, presenting severity and outcomes of stroke. Injury time-of-day effects, however, on occurrence, presenting severity and acute hospital outcomes have not been yet reported in patients with neurotrauma. Therefore, acute post-spinal cord injury hospitalization records of 759 patients from the prospective NACTN registry that contained information about the time of injury were analyzed.

Reconsidered surgical aortic valve replacement after declined transcatheter valve implantation.

Background: Outcomes for high surgical risk patients who declined transcatheter aortic valve implantation (TAVI) and then reconsidered for conventional aortic valve replacement (rSAVR) for severe calcific aortic stenosis are not well known.

Methods: This single-centre, case-control study (rSAVR vs Conservative group) retrospectively analysed patients for rSAVR (2009-2019). Multivariable logistic regression was used to identify independent predictors of composite of neurological sequelae/renal failure/deep sternal wound infection/re-exploration and death.

Effect of Transcatheter Aortic Valve Implantation vs Surgical Aortic Valve Replacement on All-Cause Mortality in Patients With Aortic Stenosis: A Randomized Clinical Trial.

Importance: Transcatheter aortic valve implantation (TAVI) is a less invasive alternative to surgical aortic valve replacement and is the treatment of choice for patients at high operative risk. The role of TAVI in patients at lower risk is unclear.

Objective: To determine whether TAVI is noninferior to surgery in patients at moderately increased operative risk.
