Complexation of 5,5,7,12,12,14-Hexamethyl-1,4,8,11-Tetraazayclotetradeca-7,14-Dienium Bromide With Copper Acetate In Methanol And Aqueous Solutions

5,5,7,12,12,14-hexamethyl-1,4,8,11-tetraazacyclodeca-7,14-dienium bromide disolvate                       ((Me6N4H4)Br2.2H2O) is a 14-membered deprotonated tetraaza macrocyclic salt. Its neutral analogues and their complexes were prepared by templation method under refluxed condition since it was discovered by Curtis in 1961. However, the present diprotonated  tetraaza salts react with many metallic salts in both methanolic and aqueous solutions. The complexation involved deprotonation of the diagonally opposite protonated amines and the type of metal salt and solvents also play an important role in the final complex formation. The complexation of (Me6N4H4)Br2.2H2O with copper acetate in methanol and aqueous solutions gave the expected complex of  [Cu((Me6N4H2)Br]Br.2H2O. Pseudo-first order condition for the complexation reaction in water was established

Global disparities in surgeons’ workloads, academic engagement and rest periods: the on-calL shIft fOr geNEral SurgeonS (LIONESS) study

: The workload of general surgeons is multifaceted, encompassing not only surgical procedures but also a myriad of other responsibilities. From April to May 2023, we conducted a CHERRIES-compliant internet-based survey analyzing clinical practice, academic engagement, and post-on-call rest. The questionnaire featured six sections with 35 questions. Statistical analysis used Chi-square tests, ANOVA, and logistic regression (SPSS® v. 28). The survey received a total of 1.046 responses (65.4%). Over 78.0% of responders came from Europe, 65.1% came from a general surgery unit; 92.8% of European and 87.5% of North American respondents were involved in research, compared to 71.7% in Africa. Europe led in publishing research studies (6.6 ± 8.6 yearly). Teaching involvement was high in North America (100%) and Africa (91.7%). Surgeons reported an average of 6.7 ± 4.9 on-call shifts per month, with European and North American surgeons experiencing 6.5 ± 4.9 and 7.8 ± 4.1 on-calls monthly, respectively. African surgeons had the highest on-call frequency (8.7 ± 6.1). Post-on-call, only 35.1% of respondents received a day off. Europeans were most likely (40%) to have a day off, while African surgeons were least likely (6.7%). On the adjusted multivariable analysis HDI (Human Development Index) (aOR 1.993) hospital capacity > 400 beds (aOR 2.423), working in a specialty surgery unit (aOR 2.087), and making the on-call in-house (aOR 5.446), significantly predicted the likelihood of having a day off after an on-call shift. Our study revealed critical insights into the disparities in workload, access to research, and professional opportunities for surgeons across different continents, underscored by the HDI

(4-Fluorophenyl)thiourea–1,10-phenanthroline (1/1)

Refluxing a mixture of 1,10-phenanthroline, (4-fluorophenyl)thiourea and cadmium(II) chloride did not produce the expected mixed-ligand complex but formed a co-crystal of the two ligands, C12H8N2·C7H7FN2S. The asymmetric unit consists of two pairs of the co-crystal molecules. In each (4-fluorophenyl)thiourea molecule, the planes of the N2CS thiourea units are almost perpendicular to the corresponding fluorobenzene rings, subtending angles of 76.53 (7) and 85.25 (7)°. In the crystal, N—H...N and N—H...S hydrogen bonds form inversion dimers from the co-crystal pairs. A weak π–π interaction between the phenanthroline rings [centroid–centroid distance = 3.7430 (15)Å] is also observed

Factors associated with usability of the EMPOWER-SUSTAIN Self-management mobile app© among individuals with cardiovascular risk factors in primary care

Objective This study aimed to determine the usability of the EMPOWER-SUSTAIN Self-Management Mobile App© and evaluate the factors associated with its usability among patients with cardiovascular risk factors in primary care. Methodology This was a cross-sectional study, conducted among patients aged ≥ 18 years with cardiovascular risk factors attending a university primary care clinic. Patients were given the app to use for at least three months. Those who fulfilled the eligibility criteria were recruited. Data gathered were on sociodemographic, clinical characteristics, self-management support by doctors, utilisation of the app at home and social support in using the app. The previously translated and validated Malay version of the mHealth App Usability Questionnaire was used to measure usability. The mean usability score was calculated and linear regressions analysis was conducted to determine the factors associated with the usability of the app. Results A total of 247 patients with at least one cardiovascular risk factor(s) were recruited. The mean age was 60.2 (±8.2). The majority were Malays (86.2%) and half of them were males (52.2%). The total mean (±SD) usability score was 5.26 (±0.67) indicating a high usability of the app. Usability of the app declined with increasing age in the simple linear regressions analysis. The multiple linear regressions yielded that being Malay ( b  = 0.31, 95% CI 0.08,0.54), using the app at home to understand their medications ( b  = 0.33, 95% CI 0.12,0.53) and having social support from family members and friends ( b  = 0.28, 95% CI 0.07,0.49) were significantly associated with higher usability of the app. Conclusion The usability of the EMPOWER-SUSTAIN Self-Management Mobile App© was high among patients with cardiovascular risk factors in our primary care clinic. This finding supports the widespread use of this app among our patients. Involvement of family members and friends should be encouraged to improve the usability of the app
