ABSTRACT
Objectives@#The aims of this study were to analyze the characteristics of the 100 top-cited articles on scrub typhus (ST), and to assess the present research landscape and future research directions using bibliometric analysis. @*Methods@#Web of Science was used to conduct a bibliometric analysis of the 100 top-cited articles on ST. The articles were analyzed by publication year, number of citations, document type, journals, keywords, institutions, country of origin, and authorship. @*Results@#The top 100 articles on ST were published between 1945 to 2017. The number of citations ranges from 39 to 227 and the interquartile range was 35.5. The United States published the highest number ( n = 21) of articles. Mahidol University was the most prolific institution in terms of articles (n =14). The American Journal of Tropical Medicine and Hygiene was the journal with the most articles (n =14), and Paris DH was the most productive author in terms of the Hirsh-index, which was 10 for that author. The study revealed a significant correlation between the total number of citations and the number of authors (r=0.668, p < 0.001), number of institutions (r = 0.692, p < 0.001), number of years since publication (r=0.869, p <0.001), and number of countries involved (r=0.963, p <0.001). @*Conclusion@#The findings of this study provide landmarks in the publication and citationfrequency of the most influential articles on ST. In addition, this study provides useful information for readers and health policy-makers in evaluating the literature on ST.

ABSTRACT
@#The first novel coronavirus case was reported on December 2019, in Wuhan, China (Xu et al., 2020), named by WHO as SARS-CoV2 and the causing disease as coronavirus disease 2019 (COVID2019). The genome sequence revealed that the virus is belongs to the beta-coronavirus group, sharing ancestry with bat coronavirus HKU9-1, similar to SARS-coronaviruses.1 The number of cases has increased within few weeks, and later spread beyond the China border.2 The epidemic of COVID-19 began in Africa later than other regions globally, perhaps, because of the limited international air traffic, rather than the climate conditions. In Africa, the first cases were reported in early March 2020 in Egypt, followed by Algeria, and Sudan.3 Sudan is located in the north-eastern Africa it occupies 1.882.000 million km square, making it third-largest country in Africa, and 16th in the world, with a population of over 40 million people.4 and Khartoum is the capital which is the main international air travel hub. Khartoum is considered the epi centre of majority of reported and imported COVID-19 cases. In this letter we describe the impact of COVID 19 in Sudan; highlighting the response towards COVID-19 pandemic and the challenges towards possible control and prevention the outbreak
ABSTRACT
Sickle cell disease (SCD) is one of the most common life-threatening monogenic disorders affecting millions of people worldwide. The disease has a high prevalence in malaria-endemic tropics, especially in sub-Saharan Africa. Although sickle-cell trait (SCT) offers protective advantage against malaria, it does not apply to homozygous individuals with sickle cell anemia but instead makes them more susceptible to not only malaria but to also other infections, causing a great deal of under-five mortality. Despite the fatal risks and high incidence rates of SCD, little attention is given, in terms of funding, management and surveillance, especially among East African countries. In addition, few works of literature exist, and less has been documented about the disease. This minireview aimed to report the current situation in terms of prevalence, mortality, diagnosis and management of SCD among East African countries; Uganda, Kenya, Tanzania, Rwanda and Burundi SCD is characterised by retarded growth, chronic pain attacks and severe organ damage leading to fatal complications. This, coupled with limited resources in East African countries, reduces the survival of SCD patients and most die before five years. SCD is detected through a blood test usually by Haemoglobin electrophoresis, and Hydroxyurea therapy, antibiotics and blood transfusion are used to prevent complications. Early childhood detection through comprehensive newborn screening programmes has been implementedin some countries and is key in the management of the disease.
ABSTRACT
Obesity and dental caries are increasing epidemics, especially among children and adolescents. This epidemiological observational cross-sectional study was conducted to assess the possible association between body mass index (BMI) and dental caries among 111,792 school children and adolescents in Jiangsu Province. We found that 13.14% participants of the study sample were overweight, and 7.37% were obese. The prevalence of dental caries was 12.95% in overweight and 7.89% in obese students. There were significant differences in caries prevalence by sex, region, age group, and BMI. Overweight and obesity statuses were associated with dental caries among the study population. BMI and dental caries present a continuous health problem. Thus, we recommend that oral health promotion be used for caries prevention and control.

Case-based surveillance measles data was defined according to World Health Organization (WHO) guidelines. A total of 511 measles cases were studied from 2011 to 2015 in Southern Darfur State, Sudan and 58.1% of cases were confirmed from Nyala city. About 43.4% of cases were males, 56.6% of cases were female, and 47.7% were children under five years old. Similarity, within February to June, the cases increased by 8.0% in children vaccinated through measles campaign, and 5.3% in children that used child vaccination card and 78.7% in unvaccinated one. The epidemiologically linked (EPI-Linked) measles cases declined from 2011 to 2015; consequently, Measles still remain to be a significant challenge in south Darfur state, Sudan.
ABSTRACT
<p><b>OBJECTIVE</b>To report the prevalence and trend of overweight and obesity among students aged 7-22 years in Jiangsu, 2010 to 2013.</p><p><b>METHODS</b>This cross-sectional study was carried out as part of students physical fitness and health survey in Jiangsu province. A total of 255,581 subjects (50.03% males and 49.97% females) enrolled in 82 school and 10 universities in Jiangsu. Weights and heights were obtained for each subject and its body mass index (BMI) was calculated using the Chinese Working Group on Obesity in China (CWGO).</p><p><b>RESULTS</b>Anthropometric measurement including bodyweight, height, BMI and bust were significantly different between males in urban compared to females living rural areas (P<0.001). The total prevalence of overweight and obesity was 12.4% and 5.7%. Males had a significantly higher rate than in female's student. The prevalence of overweight and obesity by age groups was (14.5%, 10.3%) at age 7-11 years, (11.2%, 6.8%) at age 12-14 years, (11.7%, 3.1%) at age 15-17 years, and (11.4%, 2.3%) at age 18-22 years. By regions; the highest prevalence of overweight obesity reported in Taizhou (10%, 14.2%), Xuzhou (9.4%, 12.5%), and Nanjing (9.2%, 15.6%), respectively.</p><p><b>CONCLUSION</b>The finding declares that overweight and obesity are important health problems among students in Jiangsu Province. Early intervention programme are needed to address this problems.</p>
