Lipid mediators have attracted great interest from scientists within the chemical, medicinal, and pharmaceutical research community. One such example is leukotriene B4 which has been the subject of many pharmacological studies. Herein, we report a convergent and stereoselective synthesis of this potent lipid mediator in 5% yield over 10 steps in the longest linear sequence from commercial starting materials. The key steps were a stereocontrolled acetate-aldol reaction with Nagao's chiral auxiliary and a Z-selective Boland reduction. All spectroscopic data were in agreement with those previously reported.

Forensic diagnosis of sudden cardiac death (SCD) is an extremely important part of routine forensic practice. The present study aimed to develop and validate nomograms for predicting the probability of SCD with special regards to ischemic heart disease-induced SCD (IHD-induced SCD) based on multiple autopsy variables. A total of 3322 cases, were enrolled and randomly assigned into a training cohort (n = 2325) and a validation cohort (n = 997), respectively.

In 2002, in the Emilia-Romagna region of Italy, a comprehensive strategic plan was developed with the aim of improving the integration and efficiency of the genetic services. Two decades later, this report aims to explore the current functioning of the regional network, with special focus on clinical genetics in the evolving scenarios. To this aim, we analyzed the activity data of the medical genetics services in the region, to identify and possibly improve currently open issues.

Objective: Wound management can be costly and challenging to the health services' scarce resources. Information regarding the number of wounds in a community care setting and their associated aetiology will provide nurses and nurse managers with an insight into the specific needs of these clients with wounds and highlight areas where care or services can be improved or further developed. This research aimed to establish the prevalence and aetiology of wounds, the current delivery of wound care, wound documentation and referral pathways in an Irish community care setting.

To meet wastewater treatment quality standards for reuse, integrating advanced oxidation processes (AOPs) with Decentralized Wastewater Treatment Systems (DEWATS) is promising. This study aimed to optimize AOPs (ozonolysis, UV photolysis, TiO photocatalysis) for polishing anaerobic filter (AF) effluent from DEWATS, as an alternative to constructed wetlands. Metrics included pathogen reduction efficiency, post-disinfection regrowth, and effects on physical parameters (pH, EC, turbidity), organic matter (soluble COD, BOD, DOC, humic), and nutrient concentration (ammonium, nitrates, ortho-P).

Objective: This study aimed to investigate the relationship between mortality and the frontal QRS-T angle (FQRS-TA), obtained by calculating the absolute difference between the QRS and T waves electrocardiographically (ECG), in patients diagnosed with ischemic stroke (IS).
Methods: This research is a retrospective and cross-sectional study. The diagnosis of IS was confirmed through brain imaging and physical examination.
