Una combinación de alto riesgo: obesidad,marcas de alimentación,menores y retos en YouTube

ObjectiveTo identify high-risk content in food advertising that combines obesogenic features with a highly emotionally engaging format.MethodComparison of 304 videos (47 hours and 41 minutes) from 13 food brand channels (traditional advertising) and from 15 child YouTuber channels (endorsement and influence) posted in 2019. Exploratory content analysis of variables describing the communication style of the “challenges” format.ResultsChallenges are the most common type of content (53.3%; n = 162), with a greater prevalence on child YouTuber channels (59%; n = 131) than on brand channels (41%; n = 31).ConclusionsContent created by consumers is not covered by current audiovisual communication legislation. Increased control of these practices is urgently needed, in terms of legislation, self-regulation and codes of ethics. Creativity, enjoyment or mere entertainment is not a sufficient argument for the persuasive promotion of behaviors that endanger the physical health of children.     

Trends and challenges of emergency and acute care in Chinese mainland:2005–2017

BACKGROUND:Emergency medical service system(EMSS)is essential in providing acute care services for health conditions.However,trends of emergency and acute care in China haven’t been studied systematically.METHODS:Relevant literature was carefully reviewed,including original and review articles,letters,government reports,yearbooks,both in Chinese and in English.Data on the number of emergency visits,physicians and beds in emergency departments(EDs),and the workforce of prehospital emergency care were summarized and analyzed from China Health and Family Planning Statistical Yearbooks(2006–2018).RESULTS:Over the past decade,the number of ED visits tripled from 51.9 million to 166.5 million;and utilization of pre-hospital emergency care increased from 3.2 million to 6.8 million.In response to rapid increases in demand,the number of licensed emergency physicians raised from 20,058 to 59,409;the beds’number increased from 10,783 to 42,367.For pre-hospital emergency care,the volume of health workforce increased from 3,687 to 8,671,with a 109%increase in the number of physicians from 1,774 to 3,712.However,overcrowding,the long length of stay in EDs,poor work environment,and work exhaustion were still the critical challenges faced by China’s EMSS.CONCLUSIONS:The number of emergency visits has grown with continual capability enhancement during the past decade.However,overcrowding,the long length of stay in EDs,poor work environment,and work exhaustion still need to be solved by China’s EMSS.These fi ndings and comparison with the USA could offer experiences and lessons to EMSS development worldwide,especially for developing countries.     

我国血吸虫病防治的进展、挑战与对策

血吸虫病是一种严重危害人类健康和经济社会发展的重要寄生虫病,在我国流行历史久远,分布范围广泛。中华人民共和国成立以来,我国血吸虫病防治取得了举世瞩目的伟大成就,当前疫情已得到有效控制,但要实现《“健康中国2030”规划纲要》提出的消除目标,仍面临诸多困难。本文回顾了我国血吸虫病防治的重要进展,分析了当前面临的主要挑战,并提出了如期实现消除目标的具体对策。     

Challenges in conducting post-authorisation safety studies (PASS): A vaccine manufacturer's view

Post-authorisation safety studies (PASS) of vaccines assess or quantify the risk of adverse events following immunisation that were not identified or could not be estimated pre-licensure. The aim of this perspective paper is to describe the authors’ experience in the design and conduct of twelve PASS that contributed to the evaluation of the benefit-risk of vaccines in real-world settings. We describe challenges and learnings from selected PASS of rotavirus, malaria, influenza, human papillomavirus and measles-mumps-rubella-varicella vaccines that assessed or identified potential or theoretical risks, which may lead to changes to risk management plans and/or to label updates. Study settings include the use of large healthcare databases and de novo data collection. PASS methodology is influenced by the background incidence of the outcome of interest, vaccine uptake, availability and quality of data sources, identification of the at-risk population and of suitable comparators, availability of validated case definitions, and the frequent need for case ascertainment in large databases. Challenges include the requirement for valid exposure and outcome data, identification of, and access to, adequate data sources, and mitigating limitations including bias and confounding. Assessing feasibility is becoming a key step to confirm that study objectives can be met in a timely manner. PASS provide critical information for regulators, public health agencies, vaccine manufacturers and ultimately, individuals. Collaborative approaches and synergistic efforts between vaccine manufacturers and key stakeholders, such as regulatory and public health agencies, are needed to facilitate access to data, and to drive optimal study design and implementation, with the aim of generating robust evidence.     

Vulnerable prisoners: Dementia and the impact on prisoners,staff and the correctional setting

The aim of this paper is to increase awareness and highlight the need for prisoner’s early identification of dementia and recommend support strategies within the Australian correctional setting. The number of older people is increasing within the correctional setting, causing a corresponding increase in the number of prisoners with dementia. These older prisoners are at greater risk of developing cognitive impairment and dementia which increases their vulnerability in the correctional environment including their interactions with both correctional services staff and other prisoners. Correctional settings have not been designed for older prisoners or those with dementia, which poses problems for physical and psychological health. People who have encounters with the criminal justice system are generally in poorer physical and mental health than the general population. Identifying dementia in the early stages provides opportunities to initiate strategies and supports to slow the progression. However being incarcerated increases the likelihood of not being identified with dementia until the later stages of the disease process, which significantly reduces opportunities for early intervention.     

我国家庭医生签约服务政策演变及趋势分析*

随着医药卫生体制改革的不断深入,家庭医生签约服务制度不断完善,我国已经建立了家庭医生制度和相应配套措施。自2006年起,家庭医生制度的发展可以分为三个阶段,政府根据基层卫生服务状况及相应的社会环境制订和调整了一系列政策法规。本文回顾了家庭医生制度演变,对各阶段的政策内容及特点进行了梳理。在此基础上分析了在政策指导下家庭医生签约服务面临的挑战,提出完善家庭医生制度的相应建议,为实现签约服务相应目标提供参考依据。
