Current advise to limit screen time for children [Ref-1], [Ref-2] has changed significantly with the latest 2019 guideline from the Royal College of Paediatrics and Child Health. It states that ‘The evidence base for a direct ‘toxic’ effect of screen time is contested, and the evidence of harm is often overstated.’ Key messages The evidence base for a direct ‘toxic’ effect of screen time is contested, and the evidence of harm is often overstated. The majority of the literature that does exist looks only at television screen time. Evidence is weak for a threshold to guide children and parents to
What are medical devices? Examples of medical devices include surgical lasers, wheelchairs, sutures, pacemakers, vascular grafts, intraocular lenses, and orthopedic pins.

SIGECAPS is the mnemonic we medical students memorize to learn the core symptoms of depression: sleep, interest, guilt, energy, concentration, appetite, psychomotor retardation, and suicidality. The practice questions we spend hours answering in preparation for Step 1 of the U.S. Medical Licensing Exam twist patient vignettes in tricky ways to fool us into misdiagnosing depression as insomnia in elderly women or attention deficit–hyperactivity disorder in inattentive adolescents. But despite their tricks, I would always nail those questions. The key was that if you looked hard enough, SIGECAPS was always hidden somewhere — an offhand mention of fatigue here, a seemingly

Even so, the idea that eating chocolate would protect against heart disease was always likely to be wishful thinking. An analysis of data from the Women’s Health Initiative will bring chocolate lovers down to earth (Am J Clin Nutrdoi:10.1093/ajcn/nqy073). For 13 years, the study followed more than 80 000 women who were past menopause, and found that those who ate chocolate were no less likely to develop heart disease or stroke than those who never

Introduction During the past few years the use of statins in primary prevention has come under scrutiny. In 2015 the UK chief medical officer asked the Academy of Medical Sciences to review of drug evaluation in wake of statins controversy [Ref]. The current recommendations from the US Preventive Services Task Force [link] is given below. In addition the ALLHAT RCT reports the ‘Effect of Statin Treatment vs Usual Care on Primary Cardiovascular Prevention Among Older Adults’ [Ref].
