Design, Analysis, and Testing of a Type V Composite Pressure Vessel for Hydrogen Storage.

Hydrogen, as a zero-emission fuel, produces only water when used in fuel cells, making it a vital contributor to reducing greenhouse gas emissions across industries like transportation, energy, and manufacturing. Efficient hydrogen storage requires lightweight, high-strength vessels capable of withstanding high pressures to ensure the safe and reliable delivery of clean energy for various applications. Type V composite pressure vessels (CPVs) have emerged as a preferred solution due to their superior properties, thus this study aims to predict the performance of a Type V CPV by developing its numerical model and calculating numerical burst pressure (NBP).

Laparoscopic cornual resection for interstitial pregnancy: Staying in the Marginal Zone.

Background: Fortunately, interstitial pregnancies are a rare early pregnancy presentation, yet they can be challenging to managed and are associated with a high risk of intra-abdominal haemorrhage. Once detected, surgical laparoscopic resection can be the preferred management method for both patient safety and for definitive treatment.

Objective: The video presents a new technique for laparoscopic resection of an interstitial pregnancy which enables the procedure to be effectively bloodless.

Propofol Dexmedetomidine for Conscious Sedation During Vaginal Hysterectomy With Pre-emptive Local Anesthesia: A Prospective Cohort Study.

Background/aim: Hysterectomy is the most frequent gynecological surgery. Vaginal hysterectomy (VH) seems to be related to favorable perioperative outcomes compared to abdominal or laparoscopic approaches. As the population ages, anesthesia that is safer for the elderly, such as local anesthesia (LA) with conscious sedation, is gaining popularity and is related to favorable outcomes in patients' recovery compared to general or regional anesthesia.

Barbed Sutures Compared With Conventional Sutures During Laparoscopic Myomectomy: A Systematic Review and Meta-analysis.

Objective: To accumulate the currently available literature on the safety and efficacy of the use of knotless barbed sutures for the reconstruction of the uterine wall during laparoscopic myomectomy based on comparison with traditional suture studies.

Data Sources: We searched PubMed/Medline, Scopus, ClinicalTrials.gov, and Google Scholar up to February 29, 2024.

COVID-19 Vaccination Acceptance During Pregnancy in Europe.

Pregnant women have been shown to have a higher risk of SARS-CoV-2 infection. Vaccination against the infection is the most effective strategy for preventing both severe disease and related complications. Nevertheless, vaccination hesitancy among pregnant women is an important issue affecting vaccine uptake and a major challenge for Public Health, as high rates of hesitancy can lead to complete refusal of vaccination, with health implications not only for the mother but also for the fetus.
