Secondary crystalline phases identification in Cu2ZnSnSe4 thin films: contributions from Raman scattering and photoluminescence

In this work, we present the Raman peak positions of the quaternary pure selenide compound Cu2ZnSnSe4 (CZTSe) and related secondary phases that were grown and studied under the same conditions. A vast discussion about the position of the X-ray diffraction (XRD) reflections of these compounds is presented. It is known that by using XRD only, CZTSe can be identified but nothing can be said about the presence of some secondary phases. Thin films of CZTSe, Cu2SnSe3, ZnSe, SnSe, SnSe2, MoSe2 and a-Se were grown, which allowed their investigation by Raman spectroscopy (RS). Here we present all the Raman spectra of these phases and discuss the similarities with the spectra of CZTSe. The effective analysis depth for the common back-scattering geometry commonly used in RS measurements, as well as the laser penetration depth for photoluminescence (PL) were estimated for different wavelength values. The observed asymmetric PL band on a CZTSe film is compatible with the presence of CZTSe single-phase and is discussed in the scope of the fluctuating potentials’ model. The estimated bandgap energy is close to the values obtained from absorption measurements. In general, the phase identification of CZTSe benefits from the contributions of RS and PL along with the XRD discussion.info:eu-repo/semantics/publishedVersio

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

Routine health management information system data in Ethiopia: consistency, trends, and challenges.

Background: Ethiopia is investing in the routine Health Management Information System. Improved routine data are needed for decision-making in the health sector. Objective: To analyse the quality of the routine Health Management Information System data and triangulate with other sources, such as the Demographic and Health Surveys. Methods: We analysed national Health Management Information System data on 19 indicators of maternal health, neonatal survival, immunization, child nutrition, malaria, and tuberculosis over the 2012-2018 time period. The analyses were conducted by 38 analysts from the Ministry of Health, Ethiopia, and two government agencies who participated in the Operational Research and Coaching for Analysts (ORCA) project between June 2018 and June 2020. Using a World Health Organization Data Quality Review toolkit, we assessed indicator definitions, completeness, internal consistency over time and between related indicators, and external consistency compared with other data sources. Results: Several services reported coverage of above 100%. For many indicators, denominators were based on poor-quality population data estimates. Data on individual vaccinations had relatively good internal consistency. In contrast, there was low external consistency for data on fully vaccinated children, with the routine Health Management Information System showing 89% coverage but the Demographic and Health Survey estimate at 39%. Maternal health indicators displayed increasing coverage over time. Indicators on child nutrition, malaria, and tuberculosis were less consistent. Data on neonatal mortality were incomplete and operationalised as mortality on day 0-6. Our comparisons with survey and population projections indicated that one in eight early neonatal deaths were reported in the routine Health Management Information System. Data quality varied between regions. Conclusions: The quality of routine data gathered in the health system needs further attention. We suggest regular triangulation with data from other sources. We recommend addressing the denominator issues, reducing the complexity of indicators, and aligning indicators to international definitions

However, their knowledge and attitudes toward monkeypox have not yet been assessed. Therefore, this study aimed to assess the knowledge, attitude, and factors associated with monkeypox infection among healthcare workers at Injibara General Hospital, Northwest Ethiopia.Methods: Institution-based cross-sectional study was conducted from December 1– 30, 2022. Data were collected using a structured self-administered questionnaire. A simple random sampling technique was used to select study participants. Descriptive statistics and multivariable logistic regression analyses were computed. The degree of association was interpreted using an odds ratio with a 95% confidence interval and a p-value < 0.05.Results: Among the 200 healthcare workers who participated, 38.5% (95% CI: 32.5%– 45%) and 62% (95% CI: 55– 68.5%) had good knowledge and positive attitudes regarding monkeypox respectively. Having a master’s degree or above (AOR = 11.25: 95% CI: 2.03– 62.33), being vaccinated against COVID-19 (AOR = 2.60: 95% CI: 1.37– 4.94), and having access to information about monkeypox (AOR = 3.37: 95% CI: 1.33– 8.50) were the factors associated with good knowledge. Furthermore, a positive attitude was significantly associated with being 30 years of age or older (AOR = 2.95: 95% CI: 1.55– 5.60) and having access to information about monkeypox (AOR = 4.14: 95% CI: 2.06, 8.30).Conclusion: Both good knowledge and positive attitudes were relatively low among healthcare workers. Factors such as age, education level, COVID-19 vaccination status, and access to information about monkeypox were significantly associated with the knowledge and attitude of healthcare workers. To enhance the knowledge and attitude of healthcare workers, hospitals should consider offering educational upgrades, hosting educational events like seminars, conferences, webinars, and campaigns, and ensuring comprehensive coverage of the topic in medical curricula.Keywords: monkeypox, mpox, knowledge, attitude, associated factors, healthcare worker, Ethiopia, Injibar

Perspectives of Physician and Pharmacist Stewards on Successful Antibiotic Stewardship Program Implementation: A Qualitative Study.

BackgroundAntibiotic stewardship programs (ASPs) are required at every hospital regardless of size. We conducted a qualitative study across different hospital settings to examine perspectives of physician and pharmacist stewards about the dynamics within their team and contextual factors that facilitate the success of their programs.MethodsSemistructured interviews were conducted in March-November 2018 with 46 ASP stewards, 30 pharmacists, and 16 physicians, from 39 hospitals within 2 large hospital systems.ResultsWe identified 5 major themes: antibiotic stewards were enthusiastic about their role, committed to the goals of stewardship for their patients and as a public-health imperative, and energized by successful interventions; responsibilities of pharmacist and physician stewards are markedly different, and pharmacy stewards performed the majority of the day-to-day stewardship work; collaborative teamwork is important to improving care, the pharmacists and physicians supported each other, and pharmacists believed that having a strong physician leader was essential; provider engagement strategies are a critical component of stewardship, and recommendations must be communicated in a collegial manner that did not judge the provider competence, preferably through face-to-face interactions; and hospital leadership support for ASP goals and for protected time for ASP activities is critical for success.ConclusionsThe physician-pharmacist team is essential for ASPs; most have pharmacists leading and performing day-to-day activities with physician support. Collaborative, persuasive approaches for ASP interventions were the norm. Stewards were careful not to criticize or judge inappropriate antibiotic prescribing. Further research should examine whether this persuasive approach undercuts provider appreciation of stewardship as a public health mandate
