Background: Little is known about the relationship of cognitive impairment (CI) in nursing home (NH) residents and their use of emergency department (ED) and subsequent hospital services.
Methods: We analyzed 2006 Medicare claims and resident assessment data for 112,412 Medicare beneficiaries aged >65 years residing in US nursing facilities. We estimated the effect of resident characteristics and severity of CI on rates of total ED visits per year, then estimated the odds of hospitalization after ED evaluation.
Results: Mild CI predicted higher rates of ED visits relative to no CI, and ED visit rates decreased as severity of CI increased. In unadjusted models, mild CI and very severe CI predicted higher odds of hospitalization after ED evaluation; however, after adjusting for other factors, severity of CI was not significant.
Conclusions: Higher rates of ED visits among those with mild CI may represent a unique marker in the presentation of acute illness and warrant further investigation.

Duchenne muscular dystrophy (DMD), an X-linked neuromuscular disorder, characterised by progressive immobility, chronic inflammation and premature death, is caused by the loss of the mechano-transducing signalling molecule, dystrophin. In non-contracting cells, such as neurons, dystrophin is likely to have a functional role in synaptic plasticity, anchoring post-synaptic receptors. Dystrophin-expressing hippocampal neurons are key to cognitive functions such as emotions, learning and the consolidation of memories.

Objective: To conduct a systematic review of neurocognitive dysfunctions in patients with childhood-onset schizophrenia (COS), a neuropsychiatric disorder that occurs before age 13 and is rarer and more severe than adult-onset schizophrenia.
Method: A search was made in the PubMed database. Sixty-seven studies (out of 543) which analyzed Intellectual Quotient (IQ), attentional, memory and executive functions were selected by two independent researchers.

Diabetic cognitive dysfunction is one of the important comorbidities and complications of diabetes, which is mainly manifested by loss of learning ability and memory, behavioural disorders, and may even develop into dementia. While traditional anti-diabetic medications are effective in improving cognition and memory, long-term use of these medications can be accompanied by undesirable side effects. Therefore, there is an urgent need to find safe and effective alternative therapies.
