We have developed a high resolution sequencing based typing method for genotyping Human Leukocyte Antigens (HLA) over a period of twenty years. The methods are based upon the separation of HLA alleles per locus at the initial amplification to simplify the analysis post-sequencing. The increasing discovery of polymorphism in HLA, manifested in new alleles, has necessitated the continuing development of this method. Here we present methods for the high resolution Sequence Based Typing of HLA-A, B, C (class I) and HLA-DQB1 and DRB1 (class II). The purpose of this article is to provide a valuable resource of methods and primers for other laboratories engaged in HLA typing.

Background: The Transition Shock Scale for Undergraduate Nursing Students assesses transition to undergraduate nursing students. The TSS is a tool used in various countries and has been translated into Chinese; however, associate degree nurses dominate China's nursing workforce, it needs to be validated in associate degree nursing interns. This study aimed to analyze the TSS (Chinese version) validity and reliability in Chinese associate degree nursing interns.

Background: The burden of Clostridioides difficile as a nosocomial- and community-acquired pathogen has been increasing over the recent decades, including reports of severe outbreaks. Molecular and virulence genotyping are central for the epidemiological surveillance of this pathogen, but need to balance accuracy and rapid turnaround time of the results. While Illumina short-read sequencing has been adopted as the gold standard to investigate C.

Background: Preterm birth (< 37 weeks' gestation) alters cerebrovascular development due to the premature transition from a foetal to postnatal circulatory system, with potential implications for future cerebrovascular health. This study aims to explore potential differences in the Circle of Willis (CoW), a key arterial ring that perfuses the brain, of healthy adults born preterm.
Methods: A total of 255 participants (108 preterm, 147 full-term) were included in the analysis.

Background: High quality data is important to understanding epidemiology and supporting improvement efforts in perinatal brain injury. It is not clear which data items relevant to brain injury are captured across UK sources of routinely collected data, nor what needs to be done to ensure that those sources are fit for purpose in improving care.
Methods: We reviewed data dictionaries of four main UK perinatal data sources and consulted a multi-professional group (N = 27) with expertise in neonatal/maternity care, statistics, and clinical negligence.

Ultrafine particles (UFPs) under 100 nm pose significant health risks inadequately addressed by traditional mass-based metrics. The WHO emphasizes particle number concentration (PNC) for assessing UFP exposure, but large-scale evaluations remain scarce. In this study, we developed a stacking-based machine learning framework integrating data-driven and physical-chemical models for a national-scale UFP exposure assessment at 1 km spatial and 1-hour temporal resolutions, leveraging long-term standardized PNC measurements in Switzerland.
