Abstract Racism has implicit and explicit manifestations that perpetuate disparities and negatively influence patient-centered health outcomes. Subsequently, a list of action items was provided to assist medical schools in becoming anti-racist institutions. A deep subject matter knowledge, beliefs, and reflections were a driving force for the management of medical schools or faculty members involved in undergraduate and postgraduate medical education to move forward toward inclusion of anti-racism in traditional medical curriculum or adapting existing training modules on diversity, equity, and inclusion. This paper proposes twelve practical and specific tips for implementing and teaching anti-racism in medical education. These twelve tips elaborate on the proposed actions for leaders in undergraduate and postgraduate medical education, valuable for designing future curricula and educational activities.

PurposeThis paper explores how entrepreneurial culture (EC) and organizational learning (OL) determine the entrepreneurial orientation (EO) of new technology-based firms (NTBFs). These NTBFs are located in Isfahan Science and Technology Town (ISTT), Iran. These entities face substantial challenges in a highly-sanctioned economy, which makes adopting, acquiring or transferring new technologies daunting.Design/methodology/approachThis paper analyzes a sample of 200 NTBFs. The participants were trained chief executive officers and observed by applying pre-test and post-test designs. As a final step, empirical data were collected using questionnaires and analyzed accordingly. The structural equation modeling (SEM) with the partial least squares (PLS) approach was used by the SmartPLS2 software.Findings OL was found to mediate the relationship between EC and EO in the studied NTBFs. Additionally, the indirect effect of EC on EO and the direct impact of OL on EO were significant (=1.96). Therefore, this study focuses on selected NTBFs within Iran's particular and distinctive context.Research limitations/implicationsThis study has several limitations. These were the time consuming nature, the lack of cooperation by managers and the COVID-19 pandemic-related challenges. Nonetheless, the findings offer several important implications for practitioners, scholars and policymakers.Originality/valueThe paper sought to explore how EC and OL determine EO in Iranian NTBFs. It, thus, investigates the case of a highly-sanctioned context during the coronavirus pandemic, which imposed several basic and technological limitations on their practices.

This research examines the factors contributing to the exterior material degradation of subsea oil and gas pipelines monitored with autonomous underwater systems (AUS). The AUS have a role of gathering image data that is further analyzed with artificial intelligence data analysis methods. Corrosion and potential ruptures on pipeline surfaces are complex processes involving several competing elements, such as the geographical properties, composition of soil, atmosphere, and marine life, whose eflt in substantial environmental damage and financial loss. Despite extensive research, corrosion monitoring and prediction remain a persistent challenge in the industry. There is a lack of knowledge map that can enable image ausing an AUS to recognize ongoing degradation processes and potentially prevent substantial damage. The main contribution of this research is the knowledge map for increased context and risk awareness to improve the reliability of image-based monitoring and inspection by autonomous underwater systems in detecting hazards and early signs of material degradation on subsea pipeline surfaces.

OBJECTIVE Diagnosis of Chiari I malformation (CM-1) is based on measurements of the inferior extension of the cerebellar tonsils into the foramen magnum on cranial or cervical spine magnetic resonance imaging (MRI). Imaging may be obtained before the patient is referred to the neurosurgical specialist. The length of time raises questions about the possibility that Body Mass Index (BMI) fluctuations could affect the measurement of ectopia length. However, previous literature on BMI and CM-1 has reported conflicting findings on BMI. METHODS We conducted a retrospective chart review of 161 patients who were referred to a single neurosurgeon for CM-1 consultation. Patients with multiple recorded BMI values (n=71) were compared to see if BMI changes correlated with changes in ectopia length. In addition, we compared and tested 154 recorded ectopia lengths from the patients (one per patient) and patient BMI values with Pearson's Correlation and Welch's t-tests to determine if BMI changes either influenced or were associated with ectopia changes. RESULTS For the 71 patients with multiple BMI values, change in ectopia length ranged from -4.6-9.8 mm but was not statistically significant (r = 0.019; p = 0.88). For the 154 measured ectopia lengths, changes in BMI did not correlate with ectopia length (p > 0.05). Likewise, differences in ectopia length between patients in normal, overweight, and obese categories were not statistically significant (|tstat| < |tcrit|, p > 0.05). CONCLUSION In individual patients, we found that BMI and changes in BMI were not accompanied by changes in tonsil ectopia length.

Graphene has a large optical nonlinearity and supports electrically-tunable and long-lived plasmons. We present an experimental study of harmonic generation in graphene heterostructures, which enhance the nonlinearity and allow plasmons to mediate the non-linear response.

(1) Background: Viral hepatitis C (HCV) and viral hepatitis B (HBV) are common co-infections in people living with HIV (PLWH). All PLWH should be vaccinated against HBV and hepatitis A (HAV) and treated for HBV and HCV. We aimed to compare testing, prophylaxis and treatment of viral hepatitis in PLWH in Central and Eastern Europe (CEE) in 2019 and 2022. (2) Methods: Data was collected through two on-line surveys conducted in 2019 and 2022 among 18 countries of the Euroguidelines in CEE (ECEE) Network Group. (3) Results: In all 18 countries the standard of care was to screen all PLWH for HBV and HCV both years; screening of HAV was routine in 2019 in 54.5% and in 2022 47.4% of clinics. Vaccination of PLWH against HAV was available in 2019 in 16.7%, in 2022 in 22.2% countries. Vaccination against HBV was available routinely and free of charge in 50% of clinics both in 2019 and 2022. In HIV/HBV co-infected the choice of NRTI was tenofovir-based in 94.4% of countries in both years. All clinics that responded had access to direct-acting antivirals (DAAs) but 50% still had limitations for treatment. (4) Conclusions: Although testing for HBV and HCV was good, testing for HAV is insufficient. Vaccination against HBV and especially against HAV has room for improvement; furthermore, HCV treatment access needs to overcome restrictions.

Background Mpox is a rare zoonotic disease caused by the Mpox virus. On May 21, 2022, WHO announced the emergence of confirmed Mpox cases in countries outside the endemic areas in Central and West Africa. Methods This multicentre study was performed through the Infectious Diseases International Research Initiative network. Nineteen collaborating centres in 16 countries participated in the study. Consecutive cases with positive Mpoxv-DNA results by the polymerase chain reaction test were included in the study. Results The mean age of 647 patients included in the study was 34.5.98.6% of cases were males, 95.3% were homosexual-bisexual, and 92.2% had a history of sexual contact. History of smallpox vaccination was present in 3.4% of cases. The median incubation period was 7.0 days. The most common symptoms and signs were rashes in 99.5%, lymphadenopathy in 65.1%, and fever in 54.9%. HIV infection was present in 93.8% of cases, and 17.8% were followed up in the hospital for further treatment. In the two weeks before the rash, prodromal symptoms occurred in 52.8% of cases. The incubation period was 3.5 days shorter in HIV-infected Mpox cases with CD4 count <200/μL, we disclosed the presence of lymphadenopathy, a characteristic finding for Mpox, accompanied the disease to a lesser extent in cases with smallpox vaccination. Conclusions Mpox disseminates globally, not just in the endemic areas. Knowledge of clinical features, disease transmission kinetics, and rapid and effective implementation of public health measures are paramount, as reflected by our findings in this study.
