The safety of antidepressants in pregnancy

Maternal antidepressants are implicated in ADHD, but so is maternal depression

The safety of antidepressants in pregnancy is controversial, partly because of profound methodological difficulties in separating the fetal effects of antidepressants from those related to maternal depression (confounding by indication). One central concern is the potential impact of these drugs on fetal brain development. Such effects may be subtle and possibly only detectable years after exposure, such as an increased susceptibility to (multifactorial) neurodevelopmental conditions.

Anaemia is associated with hearing loss in adults

Iron deficiency anaemia (IDA) has been found to be associated with hearing loss in adults by a study published in JAMA Otolaryngology – Head and Neck Surgery.

Using the electronic medical records of 305 339 adults aged between 21 and 90 years, researchers at Pennsylvania State University College of Medicine examined the association between IDA and sensorineural hearing loss (when there is damage to the cochlea or to the nerve pathways from the inner ear to the brain) and conductive hearing loss (hearing loss because of problems with the bones of the middle ear). IDA was determined by low haemoglobin and ferritin levels for age and sex.

Solanezumab’s failure is a wake-up call to look elsewhere for an answer to dementia

Is the amyloid cascade hypothesis of Alzheimer’s disease too big to fail? It proposes that brain deposition of β amyloid protein is the critical early event in the pathogenesis of Alzheimer’s disease and has been the centrepiece of dementia research for decades. The hypothesis suggests that removing β amyloid will reverse or prevent the clinical expression of dementia. However, in all phase III clinical trials to date, treatments targeting β amyloid have failed to improve cognitive outcomes despite reducing brain β amyloid.

Children and young people can have a wide range of life limiting conditions and may sometimes live with such conditions for many years. This guideline recommends that end of life care be managed as a long term process that begins at the time of diagnosis of a life limiting condition and entails planning for the future. Sometimes it may begin before the child’s birth. It is part of the overall care of the child or young person and runs in parallel with other active treatments for the underlying condition itself. Finally, it includes those aspects related to the care of the dying.

Swimming, aerobics, and racquet sports are linked to lowest risk of cardiovascular death

Swimming, racquet sports, and aerobics seem to be the best forms of exercise for reducing the risk of death from heart disease and stroke, research published in the British Journal of Sports Medicine has found.

The researchers said that the small number of events impaired the statistical power in some analyses. There were relatively few deaths from all causes among runners and football players, which may explain the wide confidence intervals. However, they concluded, “These findings demonstrate that participation in specific sports may have significant benefits for public health.”
