RESUMO

BACKGROUND: Globally, hepatitis B infection (HBI) poses a substantial public health concern and healthcare workers, including nursing students, are at a higher risk of contracting this disease. Thus, the study aimed to assess how knowledge, attitudes, and sociodemographic factors are associated with HBI prevention among a sample of Bangladeshi nursing students. METHODS: A cross-sectional survey was performed among 737 nursing students from the nursing institutes of Khulna and Barishal divisions in Bangladesh from January to April 2023. The data were collected by providing questionnaires (structured questionnaire) in the classroom, following a stratified random sampling process. A model of multinomial logistic regression was used to evaluate the factors linked to HBI prevention practices. RESULT: The mean (SD) scores were 11.42 (± 2.88) for knowledge, 4.33 (± 1.91) for attitude and 4.27 (± 2.056) for practice respectively. Participants' low knowledge (adjusted odds ratio, aOR = 2.562, 95% CI: 1.29-5.07) and poor attitude (aOR = 5.730, 95% CI: 3.19-10.28) regarding HBI were significantly associated with higher likelihood of poor practice towards HBI prevention. Moreover, being 2nd year of nursing students (aOR = 2.147, 95% CI: 1.19-3.86), being aged 19-20 years (aOR = 3.038, 95% CI: 1.30-7.09), being married (aOR = 0.320, 95%CI: 0.13-0.82) and having a family history of HBI (aOR = 0.134, 95%CI: 0.05-0.36) were significantly associated with poor practices of HBI prevention among study participants. CONCLUSION: The knowledge, attitude and practice scores of the nursing students on HBI prevention were suboptimal. We advocate for implementing regular HBI prevention education and policies, free or subsidized services, skill development, proper HBI prevention enforcement and strict professional ethics within nursing colleges. Such efforts should predominantly focus on second-year, aged 19-20 and unmarried nursing students.

RESUMO

Activity-driven glassy dynamics, while ubiquitous in collective cell migration, intracellular transport, dynamics in bacterial and ant colonies, etc., also extends the scope and extent of the as-yet mysterious physics of glass transition. Active glasses are hitherto assumed to be qualitatively similar to their equilibrium counterparts at an effective temperature, [Formula: see text]. Here, we combine large-scale simulations and an analytical mode-coupling theory (MCT) for such systems and show that, in fact, an active glass is inherently different from an equilibrium glass. Although the relaxation dynamics can be equilibrium-like at a [Formula: see text], effects of activity on the dynamic heterogeneity (DH), which is a hallmark of glassy dynamics, are quite nontrivial and complex. With no preexisting data, we employ four distinct methods for reliable estimates of the DH length scales. Our work shows that active glasses exhibit dramatic growth of DH and systems with similar relaxation times, and thus, [Formula: see text] can have widely varying DH. To theoretically study DH, we extend active MCT and find good qualitative agreement between the theory and simulation results. Our results pave avenues for understanding the role of DH in glassy dynamics and can have fundamental significance even in equilibrium.

RESUMO

Background: A survey of neonates with esophageal atresia and tracheoesophageal fistula (EA ± TEF) to determine additional factors responsible for poor surgical outcomes in our institution where employing an improved standard of care can ameliorate the outcome. Materials and Methods: We carried out a retrospective review of 54 neonates, who underwent surgical repair of EA± TEF over a 5-year period. We collected data regarding the patients' demographics, perioperative findings, records of neonatal intensive care, and ascertained the effects of gender, gestational age, birth weight, age at operation, type of anomaly, coexisting major anomalies, preoperative inotrope therapy, and duration of postoperative ventilation on the surgical outcome. Results: The mortality rate was 51.9%, out of which, 42.8% of neonates succumbed to ventilator-associated conditions. Age at the time of surgery, gestational age, preoperative inotrope support, presence of coexisting anomalies, and duration of postoperative ventilation were determined as the significant variables predicting mortality(P < 0.05). The area under the Receiver Operating Curve showed the duration of postoperative ventilation as the best indicator of mortality. The Logistic regression model (χ2 = 11.204, P = 0.019) with the above-mentioned variables showed that neonates who were operated before 2.5 days and who required <74.5 hours of postoperative ventilation were 3.91 and 48.30 times more likely to survive respectively, than their counterparts. Conclusion: A delay in surgery due to delayed diagnosis and or delayed transportation to tertiary centres and prolonged ventilatory support have an additional detrimental effect on the surgical outcomes of EA ± TEF.
