Objective and design: To assess the readability of the leads of the twenty-five most accessed English medical articles on Wikipedia at 0, 1, 5 and 10 years ago. Following excerpting the leads and removing mark-up, an online tool was used to assign a score to the readability of each text sample. Conclusions: The average reading grade of articles on diseases in 2018 was 12.7 (95% CI = 12.1-13.4), which was significantly easier than in 2013 and 2008 (p<0.0001). Well the average readability of English Wikipedia’s medical pages has improved as of 2018 when compared to previous years, they often remains written at a level above the reading ability of average adults

Older people with dementia gradually lose their self-care abilities as the condition of dementia progresses and this includes the ability to eat independently. Recently there have been several systematic reviews with different conclusions about the effectiveness of these interventions. This systematic review of systematic reviews included MEDLINE, Cumulative Index to Nursing and Allied Health Literature (CINAHL), PsychINFO, Excerpta Medica Database (EMBASE), the Cochrane Library and the Joanna Briggs Library) searched between January 2005-December 2018 using the search strategy: (feeding OR mealtimes OR eating OR intake OR food and drink OR nutrition OR difficulty) AND dementia AND intervention AND systematic review, evaluated using the Critical Appraisal Skills Programme checklist. There is no strong evidence to support the use of any particular intervention for the alleviation of mealtime difficulties in older people with dementia. Methodological problems related to sample size and bias were apparent in the studies included in all the reviews and there was a lack of standardisation around interventions and outcomes across studies. Behavioural intervention, specifically Montessori education and spaced retrieval methods were considered promising and worthy of further research.

Dyslexia is a neurodevelopmental disorder characterized by difficulty learning to read and spell. Underlying deficits typically include impaired phonological awareness (an awareness of the sound structure of words) and processing; difficulty with verbal working memory; and slow verbal processing speed. Observable problems include frequent spelling errors that same-age children do not exhibit; difficulty learning how to decode individual words, including "sounding out" words; and struggling to pronounce words correctly and fluently when reading aloud. Deficits in reading comprehension often occur as a secondary consequence.

Orientia tsutsugamushi is a mite-borne bacterium belonging to the family Rickettsiaceae and is responsible for the disease scrub typhus in humans. It is an obligate intracellular parasite of trombiculid mites, in which natural transmission is maintained from the female to its eggs (transovarial transmission) and from the eggs to adults (transstadial transmission). With a genome of only 2.0–2.7 Mb, it has the most repeated DNA sequences among bacteria. It is transmitted by mite larvae (chiggers) from rodents, the natural hosts of mites, to humans through accidental bites. Naosuke Hayashi first described it in 1920, giving it the name Theileria tsutsugamushi, but it was renamed to Orientia tsutsugamushi in 1995, owing to its unique properties.

Hepatitis E is inflammation of the liver caused by infection with the hepatitis E virus. It is one of five known human hepatitis viruses: A, B, C, D, and E. HEV is a positive-sense, single-stranded, nonenveloped, RNA icosahedral virus. HEV has mainly a fecal-oral transmission route. Infection with this virus was first documented in 1955 during an outbreak in New Delhi, India. A preventive vaccine (HEV 239) is approved for use in China.

Lassa fever is a viral hemorrhagic fever caused by Lassa virus. Infection with this virus may be followed by a spectrum of symptoms varies from mild acute febrile illness of brief duration to a prolonged fatal disease with severe toxaemia, capillary leakage, hemorrhagic phenomena, shock and dysfunction of organ systems. Establishing a clinical diagnosis at an early stage is especially important because of the transmissibility of infection from person to person and the need for effective isolation of the patient and for containment of potentially infectious specimens during virological and clinical testing.

The Western African Ebola virus epidemic (2013–2016) was the most widespread outbreak of Ebola virus disease (EVD) in history—causing major loss of life and socioeconomic disruption in the region, mainly in the countries of Guinea, Liberia, and Sierra Leone. The first cases were recorded in Guinea in December 2013; later, the disease spread to neighboring Liberia and Sierra Leone, while the rate among hospitalized patients was 57–59%, the final numbers 28,616 people, including 11,310 deaths, for a case-fatality rate of 40%. Small outbreaks occurred in Nigeria and Mali, and isolated cases were recorded in Senegal, the United Kingdom and Italy. In addition, imported cases led to secondary infection of medical workers in the United States and Spain but did not spread further. The number of cases peaked in October 2014 and then began to decline gradually, following the commitment of substantial international resources. As of 8 May 2016
World Health Organization (WHO) and respective governments reported a total of 28,616 suspected cases and 11,310 deaths (39.5%), though the WHO believes that this substantially understates the magnitude of the outbreak.
