    Two independent molecules that differ in terms of rotation about the central S-N bond comprise the asymmetric unit of the title compound 1. The molecules have a V-shape with the dihedral angles between the fused ring system and benzene ring being 79.08(6)° and 72.83(5)°, respectively. The packing is mostly driven by p···p interactions occurring between the tolyl ring of one molecule and the C6 ring of the indole fused ring system of the other. DFT and IRC calculations for these and related 1-(arylsulfonyl)indole molecules showed that the rotational barrier about the S-N bond between conformers is within the 2.5-5.5 kcal/mol range.

    BACKGROUND: Health systemsneed adequate personnelin order to function; improvements in health-care services delivery, and coverage and the enjoyment of standard healthcare as a right, depend on the availability, mixture, quality, and accessibility of the health-care workforce.

    PURPOSE: This review aimed to synthesize reliable evidence ondetermining factors among health science students' career choices to enhance policy advocacy for better health-care delivery.

    METHOD: We sourced empirical studies from Scopus, PubMed, ScienceDirect and Google Scholar. From a total of 9,056 researcharticlesfrom 2010 to 2022, 27 studies with a total of 45,832 respondents met the inclusion criteria.

    RESULTS: The majority of the studies were of medical students; internal medicine was the commonest choice (64.3%), with psychiatry and public health receiving lesser attention. In the four available studies of nursing students, midwifery was not chosen at all. There is a paucity of studies on this all-important concept for nursing students. The determining factors of choice of specialty were in four themes: personal, socioeconomic, professional, and educational/policy. Among the barriers to choosing particular specialties were low prestige among colleagues, stigma, long working hours, and poor public recognition.

    CONCLUSION: The career choices of health science students do not reflect an adequate mix of health-care team members to meet the health-care needs of the world. Reforms of policy and educational training are needed.

  3. Fulltext Crystal structure of 2-amino-pyridinium 6-chloro-nicotinate

    In the title salt, C5H7N(+)·C6H3ClNO(-), the 2-amino-pyri-din-ium cation inter-acts with the carboxyl-ate group of the 6-chloro-nicotinate anion through a pair of independent N-H⋯O hydrogen bonds, forming an R 2 (2)(8) ring motif. In the crystal, these dimeric units are connected further via N-H⋯O hydrogen bonds, forming chains along [001]. In addition, weak C-H⋯N and C-H⋯O hydrogen bonds, together with weak π-π inter-actions, with centroid-centroid distances of 3.6560 (5) and 3.6295 (5) Å, connect the chains, forming a two-dimensional network parallel to (100).
