Background What can the analysis of the evolution of a code of ethics tell us about the dental profession and the association that develops it? The establishment of codes of ethics are foundational events in the social history of a profession. Within these documents it is possible to find statements of values and culture that serve a variety of purposes. Codes of ethics in dentistry have not frequently presented as the subjects of analyses despite containing rich information about the priorities and anxieties within the profession's membership at the time that the code was written. Main text This essay uses critical discourse analysis to explore the 2012 and 2018 versions of the Code of Ethics produced by the New South Wales Branch of the Australian Dental Association. This method of discourse analysis examines contradictions between the discourses within the codes and how these relate to broader social realties that surround the dental profession in New South Wales. By analysing the 2012 and 2018 codes together, it is possible to understand how the dental profession views its commitments to society as established through the social contract. Through this assessment, it will be demonstrated that both codes suffer due to their failure to consider the public as a key stakeholder in the creation and curation of the Code of Ethics and how this this relates intimately with the social contract between the profession and the public. Conclusion Without the public being the central consideration, both codes amount to declarations of professional privilege and dominance. Although the more recent 2018 Code of Ethics demonstrates insight into the changes in public trust placed in the professions, this analysis shows that that the current code of ethics is still reluctant to recognise and engage with the public as an equal stakeholder in the planning and provision of oral health care and the development of the profession's values and cultural trajectory.Background Several neuraxial techniques have demonstrated effective post-cesarean section analgesia. According to previous reports, it is likely that patient-controlled epidural analgesia (PCEA) without opioids is inferior to intrathecal morphine (IM) alone for post-cesarean section analgesia. However, little is known whether adding PCEA to IM is effective or not. The aim of this study was to compare post-cesarean section analgesia between IM with PCEA and IM alone. Methods Fifty patients undergoing elective cesarean section were enrolled in this prospective randomized study. Patients were randomized to one of two groups IM group and IM + PCEA group. All patients received spinal anesthesia with 12 mg of 0.5% hyperbaric bupivacaine, 10 μg of fentanyl, and 150 μg of morphine. Patients in IM + PCEA group received epidural catheterization through Th11-12 or Th12-L1 before spinal anesthesia and PCEA (basal 0.167% levobupivacaine infusion rate of 6 mL/h, bolus dose of 3 mL in lockout interval of 30 min) was commencn incidence of delayed ambulation. Conclusions The combined use of PCEA with IM provided better post-cesarean section analgesia compared to IM alone. Trial registration UMIN-CTR (Registration No. UMIN000032475).

Our goal was to determine how the strain and sex of the mice selection would affect the development of radiation necrosis in our murine model of radiation-induced cerebral necrosis. Methods We generated this model by using a preclinical irradiator to irradiate a sub-hemispheric portion of the brain of mice with single-fraction doses of 80 Gy. Eight possible combinations of mice made up of two different with two substrains each (BALB/cN, BALB/cJ, C57BL/6 N, and C57BL/6 J) and both sexes were irradiated in this study. Radiation necrosis development was tracked up to 8 weeks with a 7 T Bruker MRI utilizing T2-weighted and post-contrast T1-weighted imaging. MRI results were compared to and validated with the use of histology which utilized a scale from 0 to 3 in ascending order of damage. Results Both time post-irradiation and strain (BALB/c vs C57BL/6) were significant factors affecting radiation necrosis development. Sex was in general not a statistically significant parameter in terms of radiation necrosis development. Conclusion Mouse strain thus needs to be considered when evaluating the results of necrosis models. However, sex does not appear to be a variable needing major consideration.Background Coronavirus disease 2019 (COVID-19) has infected more than 4 million people within 4 months. There is an urgent need to properly identify high-risk cases that are more likely to deteriorate even if they present mild diseases on admission. Methods A multicenter nested case-control study was conducted in four designated hospitals in China enrolling confirmed COVID-19 patients who were mild on admission. Baseline clinical characteristics were compared between patients with stable mild illness (stable mild group) and those who deteriorated from mild to severe illness (progression group). Results From Jan 17, 2020, to Feb 1, 2020, 85 confirmed COVID-19 patients were enrolled, including 16 in the progression group and 69 in the stable mild group. STING inhibitor Compared to stable mild group (n = 69), patients in the progression group (n = 16) were more likely to be older, male, presented with dyspnea, with hypertension, and with higher levels of lactase dehydrogenase and c-reactive protein. In multivariate logistic regression analysis, advanced age (odds ratio [OR], 1.012; 95% confidence interval [CI], 1.020-1.166; P = 0.011) and the higher level of lactase dehydrogenase (OR, 1.012; 95% CI, 1.001-1.024; P = 0.038) were independently associated with exacerbation in mild COVID-19 patients. Conclusion Advanced age and high LDH level are independent risk factors for exacerbation in mild COVID-19 patients. Among the mild patients, clinicians should pay more attention to the elderly patients or those with high LDH levels.
