Abstract Background: This study aimed to investigate the epidemiological characteristics of rubella in Beijing Haidian District of China, from 2005 to 2020, providing scientific basis for controlling the prevalence of rubella and the congenital rubella syndrome (CRS). Methods: Data were collected via the legal infectious disease report cards from medical institutions in Beijing Haidian District during 2005 to 2020. The descriptive epidemiological methods plus statistic analysis were used to analyze the distribution of rubella in terms of population, time and region. Results: In total, there were 994 cases of rubella in Beijing Haidian District, with an average annual incidence of 1.81/100,000 population. The majority of patients were at the age from 15 to 29 years old, accounting for 63.4%. And the sex ratio of male-to-female was 1.45:1. The rubella had a feature of spatial aggregation and appeared in all the regions in Haidian District. In 2007, Haidian District was hitted by rubella with the highest incidence up to 8.37/100,000, in the past 16 years. The peak incident of rubella was in May of that year, accounting for 74.8%. The majority of rubella patients were students and employees (70.1%) mainly due to the gathering. According to Joinpoint regression model, rubella would still exist in the next three years with 2-5 new cases per year. Conclusions: The number of rubella in Haidian District showed a downshift trend from 2008 to 2014 and then a sporadic distribution till 2020. Yet this disease was not completely eliminated, it is quite impending to improve the awareness of rubella and their health literacy mentally and physically in the whole population by means of the policy issuing from government.

Financial Losses

Indian Railways is the world’s largest government-owned monopoly, annually carrying passenger numbers that surpass the global population. It is world’s fourth largest rail network after the U.S.A., China, and Russia, and is managed by a separate Ministry of Railways. The operating ratios have consistently been around 90% in the past several years, indicating that that the capability to generate operational surplus is low. Further, its expenditure on staff and their pensions has been increasing. Consequently, capacity growth is increasingly being funded through borrowings, which threatens to further worsen the financial situation. Thus, railway services in India are often perceived as being inefficient and unsatisfactory. However, this perception of inefficient services has no scientific basis as mid- and micro-level efficiency analyses of Indian Railways have never been carried out. This paper adopts a data envelopment analysis (DEA)-based approach to evaluate the performance efficiencies of the 69 divisions of Indian Railways. Six models that deploy a range of performance indicators like operating expenditures, numbers of staff employed or passengers carried, freight carried, rail network length, and revenues generated have been employed to assess efficiencies. The results demonstrate the existence of significant inefficiencies that may possibly be attributed to lack of proper management, planning policies, and mis-governance, resulting in significant financial losses. The paper discusses these issues and the policy reforms needed in the developing country context, while suggesting some reforms that may lead to improved sector performances.

Epidemiological Characteristics

ObjectivesThis study aimed to investigate the epidemiological characteristics and preliminarily explore possible risk factors of physical activity-related injury (PARI) occurrences among Chinese university students via a multicentre mixed survey.DesignCross-sectional study.ParticipantsA total of 4758 undergraduates graded 1–3 in nine universities in three Chinese cities were enrolled via cluster random sampling and completed the self-administered online questionnaires during March and April 2017.Main outcome measuresPARI in the past 12 months.ResultsOf the 4758 participants, 1081 sustained PARI in the past 12 months, with an overall PARI incidence rate of 22.7% (27.3% (367/1343) in males and 20.9%(714/3415) in females). Around one-quarter of the injured (26.4%) suffered from PARI over at least three episodes. More than half of the injured subjects experienced physical activity (PA) absenteeism and sought medical attention. All PA indicators were significantly and positively associated with PARI, with a frequency of sports and leisure-time vigorous-intensity PA (VPA) participation being the strongest (adjusted OR: 1.079, 95% CI: 1.018 to 1.144). Moreover, males (OR=1.199), Shantou students (OR=4.239), year 1 students (OR=1.287), university and other sports team members (OR=1.717–2.360) and those with insufficient sleep time (OR=1.262–1.333) were also at a higher risk of PARI.ConclusionsPARI is prevalent among university students in China. The frequency of sports and leisure-time VPA participation was most strongly associated with PARI among all PA indicators. These data can inform future programmes for injury intervention among university students. Safety issues should also be emphasised when promoting PA among the public to reduce PARI.

Background: The primary aim of this study is to describe current trends in racial-, age- and sex-specific incidence, clinical characteristics and burden of cerebral venous thrombosis (CVT) in the United States (US). Methods: Validated International Classification of Disease codes were used to identify all adult new cases of CVT (n=5,567) in the State Inpatients Database of New York and Florida (2006-2016) and all cases of CVT in the entire US from the National Inpatient Sample 2005-2016 (weighted n=57,315). Incident CVT counts were combined with annual US Census data to compute age and sex-specific incidence of CVT. Joinpoint regression was used to evaluate trends in incidence over time. Results: From 2005-2016, 0.47%-0.80% of all strokes in the US were CVTs but this proportion increased by 70.4% over time. Of all CVTs over this period, 66.7% were in females but this proportion declined over time (p<0.001). Pregnancy/puerperium (27.4%) and cancer (11.8%) were the most common risk factors in women, while cancer (19.5%) and central nervous trauma (11.3) were the most common in men. Whereas the prevalence of pregnancy/puerperium declined significantly over time in women, that of cancer, inflammatory conditions and trauma increased over time in both sexes. Annual age and sex-standardized incidence of CVT in cases/million population ranged from 13.9-20.2, but incidence varied significantly by sex (women: 20.3-26.9; men 6.8-16.8) and by age/sex (women 18-44yo: 24.0-32.6%; men: 18-44yo: 5.3-12.8). Age and sex-standardized incidence also differed by race (Blacks:18.6-27.2; whites: 14.3-18.5; Asians: 5.1-13.8). On joinpoint regression, incidence increased across 2006-2016 but most of this increase was driven by increase in all age groups of men (combined annualized percentage change (APC) 9.2%, p-value <0.001), women 45-64 yo (APC 7.8%, p-value <0.001) and women ≥65 yo (APC 7.4%, p-value <0.001). Incidence in women 18-44 yo remained unchanged over time . Conclusion: The epidemiological characteristics of CVT patients in the US is changing. Incidence increased significantly over the last decade. Further studies are needed to determine whether this increase represents a true increase from changing risk factors or artefactual increase from improved detection.

Astronomy, unlike most other sciences, arouses great curiosity amongst laypeople. It is a subject that can be described relatively easily in public lectures. Distinguished astronomers like James Jeans and Arthur Eddington in the past and many more in recent times have “stooped down” to the public level to share the excitement of astronomical discoveries. Today, the popularization program normally proceeds in four different ways — through popular articles, public lectures, planetarium shows, and radio – TV programs. However, this overwhelming public interest in astronomy brings its own difficulties. Not all of it is motivated by a scientific interest! Many persons read mystic significance into astronomical findings. Many more are guided by astrological interest. Many fail to perceive the scientific basis for astronomy, a subject whose laboratory is the whole cosmos with objects too remote to be subject to scientific experimentation.

This study investigates the pattern of use of traditional and alternative healers among psychiatric patients in Nelson Mandela Metropole. An interview schedule was applied to 254 subjects at six sites, enquiring about consultations with traditional and alternative healers in the past year. Multivariate analysis was performed to determine predictors of consultation. Overall, 78 (31%) of respondents had consulted a healer in the past year. The ethnic distribution was: 156 (61%) Black, 53 (21%) Coloured (Mixed Race), 42 (17%) White and three (1%) Indian. The male to female ratio was 119 (46.85%):135 (53.14%). The healers gave no advice about psychiatric medication to 48 (61.5%) of consulters, 23 (29.5%) were told to continue their medication, four (5.1%) told to stop, and one (1.3%) told to stop and restart later. In multivariate models, predictors of consultation were being Black and of lower education. Although 45 (58%) of the consulters indicated that medical treatment was more helpful than the healer’s, 45 (58%) intended to consult again. Overall, 22% of consulters reported abuse by the healer.

Abstract Background This study aimed to analyse the epidemiological characteristics of bacillary dysentery (BD) caused by Shigella in Chongqing, China, and to establish incidence prediction models based on the correlation between meteorological factors and BD, thus providing a scientific basis for the prevention and control of BD. Methods In this study, descriptive methods were employed to investigate the epidemiological distribution of BD. The Boruta algorithm was used to estimate the correlation between meteorological factors and BD incidence. The genetic algorithm (GA) combined with support vector regression (SVR) was used to establish the prediction models for BD incidence. Results In total, 68,855 cases of BD were included. The incidence declined from 36.312/100,000 to 23.613/100,000, with an obvious seasonal peak from May to October. Males were more predisposed to the infection than females (the ratio was 1.118:1). Children < 5 years old comprised the highest incidence (295.892/100,000) among all age categories, and pre-education children comprised the highest proportion (34,658 cases, 50.335%) among all occupational categories. Eight important meteorological factors, including the highest temperature, average temperature, average air pressure, precipitation and sunshine, were correlated with the monthly incidence of BD. The obtained mean absolute percent error (MAPE), mean squared error (MSE) and squared correlation coefficient (R2) of GA_SVR_MONTH values were 0.087, 0.101 and 0.922, respectively. Conclusion From 2009 to 2016, BD incidence in Chongqing was still high, especially in the main urban areas and among the male and pre-education children populations. Eight meteorological factors, including temperature, air pressure, precipitation and sunshine, were the most important correlative feature sets of BD incidence. Moreover, BD incidence prediction models based on meteorological factors had better prediction accuracies. The findings in this study could provide a panorama of BD in Chongqing and offer a useful approach for predicting the incidence of infectious disease. Furthermore, this information could be used to improve current interventions and public health planning.

Although there is a worldwide increase in maxillofacial trauma incidence; the pattern and etiology of these injuries varies from one country to another depending on socioeconomic, cultural, and environmental factors. This study aims to realize the epidemiological characteristics of maxillofacial fractures in our department. A retrospective cross-sectional study of all facial trauma patients admitted to our department during 2009 to 2012. Patients’ data including gender, age, etiology of trauma, the pattern and demographic distribution of fractures of maxillofacial skeleton, and associated injuries were analyzed and compared with previously published data. The chi-square test was used with a p value of less than 0.05, which was considered statistically significant. There is a significant increase in maxillofacial fractures incidence in the past 2 years than former ones. There is a male predominance with highest incidence in the age group of 20 to 40 years. Road traffic accident is the most common etiological factor followed by violence. There is increase in mandibular fracture incidence compared with midface. The significant increased incidence of maxillofacial fracture due to motor car accidents and assaults in the past 2 years reflects a behavioral change within the community.

Aims.This study aims to examine Queensland suicide trends in the Australian-born population and in the overseas-born populations over the past 2 decades.Methods.All suicide cases for the period 1991–2009 were identified in the Queensland Suicide Register. Age-standardised suicide rates were calculated. Joinpoint regression and Poisson regression were applied.Results.A significant decline in suicide rates of young (15–44 years) overseas-born males was reported over the past 2 decades. Australian-born young males showed significant increase until 1996, followed by a significant decline; furthermore, their suicide rates were significantly higher when compared to overseas-born (RR = 1.36, 95%CI: 1.15; 1.62). Contrary older Australian-born males (45+ years) had significantly lower suicide rates than overseas-born males (RR = 0.90, 95%CI: 0.83; 0.98). Despite the convergence of the suicide trends for older males, changes were not significant. While Australian-born females had a significant increase in suicides, overseas-born females had a decline in 1991–2009.Conclusions.Conclusion. Significantly declining suicide rates of migrants have contributed to the declining in suicide trends in Queensland. Potential reasons for significantly lower suicide rates among young migrants might include the change in the nature of migration from involuntary to voluntary.

Main Factor

Personal reflections on radiation hormesis for the past 50 years are presented. The causes of ignoring and rejections of this phenomenon by international and national bodies and by radiation protection establishment are analyzed. The opposition against nuclear weapons and preparations for nuclear war was probably the main factor in inducing the concern for adverse effects of low doses of ionizing radiation, a byproduct of activism against the nuclear weapon tests. UNSCEAR was deeply involved in preparation of the scientific basis for cessation of nuclear test, and contributed to elaboration of the LNT assumption, which is in contradiction with the hormetic phenomenon. However, this authoritative body recognized also the existence of radiation hormesis, termed as ‘adaptive response.’ The political and vested interests behind exclusion of hormesis from the current risk assessment methodology are discussed.

The past 25 years have brought dramatic improvements in mortality rates in Great Britain. Infant mortality is now about 40% of what it was a quarter of a century ago: death-rates for children have been reduced to less than 1 per 1000. Not only children have benefited; young adults in the 15–44 age-group experience mortality little more than a third of what it was in the early thirties, whilst women aged 45–64 have had an improvement of about 40%.It is therefore regrettable that the experience of men aged 45–64 is a black spot in the general picture. The improvement for men in this age-group has not kept pace with that for women of the same age, being only about 15% in 25 years, little more than ½% a year. Table 1 compares the death-rates for men and women in post-war years and demonstrates very clearly how over a period of 12 years the ratio of male to female mortality has steadily increased.
