Aim: The world is affected by the severe acute respiratory syndrome coronavirus2 (SARS-CoV-2) pandemic. This virus has emerged as a human pathogen that can cause symptoms ranging from fever to Pneumonia, but it remains asymptomatic or mild. To better understand the virus's ongoing spread, identify those who have been infected, and track the immune response, accurate and robust immunological monitoring and SARS-CoV-2 detection assays are needed. Methods: The estimation of serology tests to assess the presence of antibodies to SARS-CoV-2 in COVID- 19 patients at Asian Institute of Medical Sciences (AIMS) and Isra University & hospital. 1229 patients were selected including males and females with the age being 25 to 65 years living in the territories from 1st August to 30th November 2020. The anti-SARS-CoV-2 test was performed by an electrochemiluminescence immunoassay analyzer. Results: Out of 1229 participants 206 (17%) were positive with COVID-19, and 1023 (83%) were negative. The results further revealed that a higher percentage of positive COVID-19 were detected in males in all age groups as compared to females, and most of them are affected at age of 46-65 years male 40 (24.69%) and female 14(17.5%). Conclusion: The seroprevalence of SARS-COV-2 antibodies has increased in the old age population, which may aid in determining the true number of infected cases. Although the current study is based on a small sample of participants, the findings suggest a study with a larger population to implement stronger and targeted interventions.

Probability Of Cancer

Introduction: Computer Tomography (CT) scans can deliver a relatively high radiation dose to the patient, therefore radiation protection for this modality is paramount. The present study determined the frequency of no abnormality detected (NAD) brain CT scans and probability of cancer induction in different age groups and genders. Methods: In this study, brain CT reports were used to identify any findings as abnormality detected (AD) and others as NAD. Then probability of future leukemia and brain cancer was estimated for different age and gender groups. Results: On average, in 65% of the cases the results were NAD (56% and 76% among males and females, respectively). Among children, 79% of the reports were NAD. The total number of projected brain cancers was 1.8 and 1.3 for males and females, respectively. The number of projected leukemia cases was 0.75 and 0.7 for males and females, respectively. For pediatric patients, brain CT scans can lead to leukemia cases about 4.5 times more often than adults. Conclusion: Brain CT scans can lead to additional cases of brain cancer and leukemia. A significant fraction of brain CTs were NAD (non-pathologic) and could practically be replaced by other radiation-free imaging modalities, especially in pediatric and young patients.

Abstract We study size-at-age and sexual variability of morphometric characteristics of the marsh frog. According to the size of the body, males were divided into three size-age groups (juvenis, subadultus, adultus), females — into four groups (juvenis, subadultus, adultus, adultus-I). We found that the chronological age of frogs (skeletochronology) does not always correspond to their biological age (size and proportions of the body). We noted that the semi-adult males are reliably larger than females by mean values of 26 studied morphometric characters. Males and females of “adultus” group do not differ by linear body size, significant differences were found in body proportions (7 characters). For the females of “adultus-I” group, the mean values of 26 characters are significantly larger than for “adultus” males. The results of our study showed that with the age of the marsh frog, the level of exhibition, directionality and structure of morphometric sex differences changes.

Abstract Background Medical regulators worldwide have implemented programmes of maintenance of professional competence (MPC) to ensure that doctors, throughout their careers, are up to date and fit to practice. The introduction of MPC required doctors to adopt a range of new behaviours. Despite high enrolment rates on these programmes, it remains uncertain whether doctors engage in the process because they perceive benefits like improvements in their practice and professional development or if they solely meet the requirements to retain medical registration. In this study, we aimed to explore the relationship between doctors’ beliefs, intention and behaviour regarding MPC through the lens of the Theory of Planned Behaviour (TPB) to make explicit the factors that drive meaningful engagement with the process. Methods We conducted a qualitative study using semi-structured interviews. From a pool of 1258 potential participants, we purposively selected doctors from multiple specialities, age groups, and locations across Ireland. We used thematic analysis, and the TPB informed the analytic coding process. Results Forty-one doctors participated in the study. The data analysis revealed doctors’ intention and behaviour and the factors that shape their engagement with MPC. We found that attitudes and beliefs about the benefits and impact of MPC mediated the nature of doctors’ engagement with the process. Some participants perceived positive changes in practice and other gains from participating in MPC, which facilitated committed engagement with the process. Others believed MPC was unfair, unnecessary, and lacking any benefit, which negatively influenced their intention and behaviour, and that was demonstrated by formalistic engagement with the process. Although participants with positive and negative attitudes shared perceptions about barriers to participation, such perceptions did not over-ride strongly positive beliefs about the benefits of MPC. While the requirements of the regulator strongly motivated doctors to participate in MPC, beliefs about patient expectations appear to have had less impact on intention and behaviour. Conclusions The findings of this study broaden our understanding of the determinants of doctors’ intention and behaviour regarding MPC, which offers a basis for designing targeted interventions. While the barriers to engagement with MPC resonate with previous research findings, our findings challenge critical assumptions about enhancing doctors’ engagement with the process. Overall, our results suggest that focused policy initiatives aimed at strengthening the factors that underpin the intention and behaviour related to committed engagement with MPC are warranted.

AbstractCurrent discussions of the social phenomenon of “vaccine hesitancy” with regard to Covid-19 provide an opportunity to use hesitancy as a means to shift thinking about untimely and delayed responses to forecasts of hydrometeorological hazards. Hesitancy, that is, provides a paradigm through which such regrettably delayed responses to hydromet hazards might be better understood and effectively addressed. Without exaggeration, just about every hydromet event provides an example of how hesitancy hinders individual, community, and national government risk-reducing preventive and mitigative responses to forecasts of foreseeable, relatively near-term climate, water, or weather hazards. Reasons for such hesitancy (for vaccine and forecast use alike) include—among others—lack of trust in the science, lack of confidence in government, and persistent concern about the uncertainties that surround forecasting—both meteorological and public health. As such, a better understanding of the causes that lead to individual and group hesitancy can better inform hydromet forecasters and affected communities about ways in which beneficial actions in response to timely forecasts are often delayed. This better understanding will facilitate, where necessary, targeted interventions to enhance the societal value of forecasting by reducing this long-observed challenge of “forecast hesitancy.” First, this article focuses on incidents of “vaccine hesitancy” that, for various reasons, people around the world are even now experiencing with regard to several now-available, and confirmed efficacious, Covid-19 vaccines. Reports of such incidents of indecisiveness first increased dramatically over the first few months of 2021, despite the strong scientific confidence that vaccination would significantly lower personal risk of contracting as well as spreading the virus. After, the notion of forecast hesitancy with regard to hydrometeorological hazards is discussed.It’s not what you say, it’s what people hear.-Frank Luntz (2007)

Age and length data of 291 franciscana dolphins (Pontoporia blainvillei) incidentally captured on the coast of Rio Grande do Sul State (RS), southern Brazil, were used to fit growth curves using Gompertz and Von Bertalanffy growth models. A small sample of franciscanas (N = 35) from Buenos Aires Province (BA), Argentina, were used to see if there are apparent growth differences between the populations. Male and female franciscana samples from both areas were primarily (78–85%) <4 years of age. The Von Bertalanffy growth model with a data set that excluded animals <1 year of age provided the best fit to data. Based on this model, dolphins from the RS population reached asymptotic length at 136.0 cm and 158.4 cm, for males and females, respectively. No remarkable differences were observed in the growth trajectories of males and females between the RS and BA populations.

The Relationship

SARS-CoV-2 causes coronavirus disease 2019 (COVID-19) and is responsible for the recent pandemic in the world. It has been recently recognized as a challenge for public health and a significant cause of severe illness in all age groups. Young children and older people are susceptible to SARS-CoV-2 infection. However, children usually present mild symptoms compared to adult patients. The relationship between age, severity, and COVID-19 transmission is compared to determine whether there is any reasonable relationship between age and COVID-19. It should be mentioned that some risk factors may increase the probability of developing severe COVID-19 by advancing age, such as pathophysiological changes in the respiratory system, angiotensin-converting enzyme 2 expression in the nasopharynx, and smoking. Susceptibility to SARS-CoV-2 infection is independent of age, but the mortality rate of COVID-19 depends on age.

Abstract In Ethiopia, the gender gap in financial inclusion is high, and the effect of socioeconomic variables on the gap is not well investigated. As a result, this study uses the World Bank’s Global Findex database from 2017 to analyze magnitude and determinants of the gender gap in financial inclusion in Ethiopia. Using Fairlie decomposition technique, we find statistically significant gender gap in all indicators of financial inclusion under study in Ethiopia. The result shows that the highest financial inclusion gender gap is observed in formal saving followed by formal account holding. The decomposition results show males are 16.5%, 16.6%, 8.9 %, 8.4 %t, and 5.8% more likely to have a formal account, formal saving, borrowing, emergency fund possibility, and debit card ownership, respectively. We further decompose these gaps using Daymont and Andrisani approach and the result reveals that differences in coefficients between males and females explain 57.7% in formal saving, 43.4% in formal account holding, and 110.9% in borrowing from formal financial institutions. About 54.2% of the total gender gap in possibility of raising emergcency fund is attributed to differences in characteristics/predictors between the two genders while gender gap in debit card holding is explained by the iteraction between differences in characterisctics and coefficients. Being older, more educated, and wealthier favor financial inclusion, with age, employment, and education having a greater effect. Furthermore, gaps in coefficients, productivity, and advantage to males and disadvantage to females aggravate the gender gap in financial inclusion in Ethiopia. Gender mainstreaming in economic activities to increase income, employment opportunities and education for females to bridge the gender gap in financial inclusion is important.

Over Time

Because we observed increasing incidences over time, advancing age, higher estrogen levels, decreasing UVB (290-315 nm) doses, or lower vitamin D3, and Human Papillomavirus hiding in immune-privileged sites of hair follicles play roles in melanoma, we wondered if the majority of cancers might have similar carcinogenic drivers. To investigate this possibility, we performed worldwide analysis of all sites but skin cancer over time (1955-2007), advancing age, and UVB doses for males and females with all skin types and ages (0-85+) and in five age groups using IARC data. To investigate Human Papillomavirus’s role, we analyzed the incidences of breast, prostate, and colon cancers in a developed country with European ancestry (New Zealand) having high amounts of androgenic hair and a developing country with Asian ancestry (India) having low amounts of androgenic hair. To potentially add epidemiology to the already established role of estrogen in cancer, we analyzed males and females in various countries around the world using the incidence of breast cancer (> 70 yr.) as an established indicator of estrogen levels. The analysis reveals cancer incidences are steadily increasing over time in developed but not developing countries regardless of skin type. Only US white, but not black, breast, prostate, and colon cancer incidences in the oldest age group significantly decreased with increasing UVB dose suggesting a role for vitamin D3. The data suggests the carcinogenic drivers in many cancers are estrogen, increasing age (or reactive oxygen species), decreasing vitamin D3 levels, and persistence of Human Papillomavirus infection in immune-privileged sites.
