- Abstract：The ongoing Ebola outbreak poses an alarming risk to the countries of West Africa and beyond. On August 8, 2014, the World Health Organization (WHO) declared the cross-country Ebola outbreak a Public Emergency of International Concern. China has had no confirmed cases of Ebola. In this paper, virologic characteristics, pathogenesis, clinical manifestations, laboratory examination and prophylactic vaccines and therapeutic drugs of Ebola are summarized. Importantly, active responses and actions from China are introduced. Moreover, the key issues in the future prevention and control of Ebola were also addressed.Keywords：Ebola virus;Ebola virus disease;Prevention and control5|17|2Updated：2022-12-27

Abstract：Background:Chronic hepatitis is a major public health problem. The hepatitis B virus is the primary cause, and Hepatitis B and C together are responsible for 60% of cirrhosis and 80% of hepatocellular carcinomas. This study measured the prevalence of HBsAg among Senegalese military to develop a strategy to prevent cirrhosis and hepatocellular carcinoma in the army.Methods:We conducted a descriptive cross-sectional study among Senegalese army staff aged 25 to 60 years and divided this group into three strata: 25-34, 35-44 and 45-60 years. A sample of 1224 participants was selected following a two-level stratification. The mark of surface HBs antigen (Ag) was performed on 1195 participants using chemiluminescence (qualitative Architect HBs Ag of Abbott Diagnostics Laboratories Germany) and enzyme immunoassay (Determines HBsAg) methods. The presence of HBsAg was analyzed according to age, marital status, alcohol consumption and glomerular filtration rate. Epi-info6 and R software were used, respectively, for data capture and analyses. A Chi-square test was performed to compare proportions considering an alpha significance level of 5% and a confidence interval of 95%.Results:The average age was 39.8±9.2 years. Participants in the age groups of 25-34 years, 45-60 years and 35-44 years were 30.7%, 34.4% and 34.9% of the sample, respectively. Married persons accounted for 82.6% of participants, and 17.08% were single. Most participants were educated (99%), and 56% had reached at least the secondary school level. Alcohol consumption was at 11.5%. The HBsAg prevalence rate was 10.8% [9.1% to 12.7%] with a significant difference between age groups (P<0.001), which ranged from 5.6% for 45-60 years, 9.62% in the 25-34 years group and 16.9% for the 35-44 years group. Marital status and alcohol consumption did not affect the carriage of HBsAg. The prevalence of HBsAg was more common among participants who had a glomerular filtration rate greater than 90 ml/min. Transaminases rate exceeded the normal threshold in 43 participants (3.6%). The increase was 6.6% [2.7% to 11.8%] of HBsAg carriers and 3.2% [1.2% to 6.7%] of alcohol users.Conclusion:The high prevalence of HBsAg in the military requires the implementation of an accessible prevention and care program to reduce the risk of cirrhosis and hepatocellular carcinoma. This program will contribute to reducing the burden of communicable diseases, such as hepatitis and HIV/AIDS, and non-communicable diseases in the armed forces.Keywords：Seroprevalence;HBsAg;Military;Chronic diseases4|9|0Updated：2022-12-27

Abstract：The outbreak of Ebola virus disease (EVD) continues to spread through West Africa. Since the first reported EVD in March 2014, the number of cases has increased rapidly, with the fatality rate of >50%. The most prevalent Ebola virus belongs to the species of Zaire ebolavirus, with a mortality rate as high as 90%. Although there were introduced cases in other continents, Africa is the endemic area where fruit bats and apes are suspected to be Ebola virus carriers. The virus might be transmitted from the host animals to humans if humans consume relative raw and contaminated meats; however, human-to-human transmission via close contact is the major route of current outbreaks. EVD happens at any seasons and affected people of any race in any age groups. Direct contact with body fluids of EVD patients and living in the contaminated environment greatly increase the risk of being infected. Transmission via aerosol is less possible but the transmission via droplet is possible in humans. Thus, health care providers are facing danger of getting Ebola virus infection. So far, there are limited vaccines, drugs and/or therapies to prevent Ebola virus infection or treat EVD. Medical workers should follow the current standard prophylactic procedures. Military forces can orchestrate efficient care to mass EVD casualties. Although it is necessary to speed up the pace of developing effective vaccine and therapeutics for the prevention and treatment of EVD, public health prophylaxis is the most important issue at present to control the spread of this disease cost-effectively.Keywords：Ebola virus disease;epidemiology;Outbreak;Virology;Prophylaxis6|33|6Updated：2022-12-27 - Abstract：The incidence of sepsis is increasing over time, along with an increased risk of dying from the condition. Sepsis care costs billions annually in the United States. Death from sepsis is understood to be a complex process, driven by a lack of normal immune homeostatic functions and excessive production of proinflammatory cytokines, which leads to multi-organ failure. The Toll-like receptor (TLR) family, one of whose members was initially discovered in Drosophila, performs an important role in the recognition of microbial pathogens. These pattern recognition receptors (PRRs), upon sensing invading microorganisms, activate intracellular signal transduction pathways. NOD signaling is also involved in the recognition of bacteria and acts synergistically with the TLR family in initiating an efficient immune response for the eradication of invading microbial pathogens. TLRs and NOD1/NOD2 respond to different pathogen-associated molecular patterns (PAMPs). Modulation of both TLR and NOD signaling is an area of research that has prompted much excitement and debate as a therapeutic strategy in the management of sepsis. Molecules targeting TLR and NOD signaling pathways exist but regrettably thus far none have proven efficacy from clinical trials.Keywords：Innate immunity;TLR signaling;NOD signaling;sepsis5|49|14Updated：2022-12-27
- Abstract：Hearing plays a vital role in the performance of a soldier and is important for speech processing. Noise-induced hearing loss is a significant impairment in the military and can affect combat performance. Military personnel are constantly exposed to high levels of noise and it is not surprising that noise induced hearing loss and tinnitus remain the second most prevalent service-connected disabilities. Unfortunately, unlike civilian personnel, military personnel have little option but to remain in noisy environments in order to complete specific tasks and missions. Use of hearing protection devices and follow-up audiological tests have become the mainstay of prevention of noise-induced hearing loss. This review focuses on sources of noise within the military, pathophysiology and management of patients with noise induced hearing loss.Keywords：Hearing loss;noise-induced;Military personnel;Ear protective devices4|7|2Updated：2022-12-27
- Abstract：With the rapid development of electronic technologies, anxiety regarding the potential health hazards induced by microwave radiation (MW) has been growing in recent years. The brain is one of the most sensitive target organs for microwave radiation, where mitochondrial injury occurs earlier and more severely than in other organs. Energy metabolism disorders do play an important role during the process of microwave radiation-induced brain damage. In this paper, we will review the biological effects of microwave radiation, the features of brain energy supply and consumption and the effects of microwave radiation on mitochondrial energy metabolism and potential related mechanisms.Keywords：Microwave radiation;Brain;Energy metabolism;mitochondria;Mechanisms4|16|6Updated：2022-12-27

Abstract：The Mesoamerican Ministers of Health have set 2020 as the target for malaria elimination to be achieved in the region. Imported malaria cases are a potential threat to countries attempting elimination or working to prevent resurgence. We report the first imported Plasmodium ovale infection with molecular confirmation in Central America, which occurred in a Guatemalan soldier that had been deployed in Africa. The obstacles for its diagnosis using the standard microscopy technique and the need to improve its detection are discussed.Keywords：Plasmodium ovale;Imported malaria;diagnosis0|0|0Updated：2026-03-12
