In the title mol-ecular salt [systematic name: triethylammonium 5-(2,4-dinitrophenyl)-2,6-dioxo-1,2,3,6-tetrahydropyrim-idin-4-olate], C(6)H(16)N(+)·C(10)H(5)N(4)O(7) (-), the cation and anion are linked by an N-H⋯O hydrogen bond. In the crystal, inversion-related barbiturate rings are centrosymmetrically connected through pairs of N-H⋯O hydrogen bonds, forming R(2) (2)(8)R(2) (2)(8) ring motifs.

THE ASYMMETRIC UNIT OF THE TITLE COMPOUND [SYSTEMATIC NAME: 9,10-dimeth-oxy-7-methyl-6,7,7a,8-tetra-hydro-5H-benzo[g][1,3]benzodioxolo[6,5,4-de]quinoline], C(20)H(21)NO(4), contains two independent mol-ecules with very similar bond lengths and angles. The crystal packing exhibits voids of 131 Å(3).

OBJECTIVE A prospective epidemiological study was conducted at a fly-in-fly-out mining operation in Australia to assess the dynamics of occupational fatigue and its potential risk factors. METHODS Performance and perceived fatigue were measured at the start/finish of each 12-h shift throughout the 28-day roster (10 days day shift work on-site, 5 days rest off-site, 8 days night shift work on-...

BACKGROUND Staff turnover of professional nurses remains a concern for public and private hospitals management because it has an impact on the morale of nurses and it may also lead to poor patient care. OBJECTIVES The objectives of this study were to explore and describe the experiences of nursing unit managers with regard to the turnover of professional nurses who were under their supervisio...

For the purpose of examining the relation of sleep problems and other possible correlates with smoking among staff nurses in hospitals, the cross-sectional data of a self-administered questionnaire survey for 522 Japanese female staff nurses were reanalyzed. Registered nurses or licensed practical nurses were 82%, while nursing assistants were 18%. The prevalence of current smoking (PCS) was 29...

BACKGROUND Clinical supervision and feedback are important for the development of competency in junior doctors. This study aimed to determine the adequacy of supervision of junior medical staff in Australian emergency departments (EDs) and perceived feedback provided. METHODS Semi-structured telephone surveys sought quantitative and qualitative data from ED Directors, Directors of Emergency M...

BACKGROUND Accreditation Council on Graduate Medical Education (ACGME) duty hour restrictions have led to the widespread implementation of non-house staff services in academic medical centers, yet little is known about the quality and efficiency of patient care on such services. OBJECTIVE To evaluate the quality and efficiency of patient care on a physician assistant/hospitalist service compa...

Background Employees working in emergency departments (EDs) in hospital settings are disproportionately affected by workplace violence as compared to those working in other departments. Such violence results in minor or major injury to these workers. In other cases, it leads to physical disability, reduced job performance, and eventually a nonconducive working environment for these workers. M...
