Poor sleep contributes to the developmental problems seen in preterm infants. We evaluated sleep problems in preterm infants 6 months of post-gestational age using the subjective Brief Infant Sleep Questionnaire (BISQ) and objective sleep tests. We also compared the sleep of premature infants with that of full-term infants. The study included 68 6-month-old full-term healthy infants and 191 premature infants born at 1 event/hour as indicated by the questionnaire. Premature infants have more sleep problems than full-term infants, including the known risk of abnormal breathing during sleep, which has been well demonstrated already with the BISQ-Chinese (CBISQ).

As the number of cardiac implantable electronic devices (CIEDs) is increasing annually, CIED-related complications are becoming increasingly important. The aim of the study was to assess the risks associated with CIEDs by a nationwide database. Patients were selected from the Taiwan National Health Insurance Database. Admissions for CIED implantation, replacement, and revision were evaluated and the evaluation period was 14 years. Endpoints included CIED-related infection, pneumothorax, and heart perforation. The study included 40,608 patients with a mean age of 71.8 ± 13.3 years. Regarding infection, the incidence rate was 2.45 per 1000 CIED-years. Male gender, younger age, device replacement, and previous infection were risks for infection while old age and high-volume centers (>200 per year) were protectors. The incidence of pneumothorax was 0.6%, with an increased risk in individuals who had chronic obstructive lung disease (COPD) and cardiac resynchronized therapy (CRT). The incidence of heart perforation was 0.09%, with an increased risk in individuals who had pre-operation temporal pacing and steroid use. High-volume center was found to decrease infection rate while male gender, young people, and individuals who underwent replacements were associated with an increased risk of infection. Additionally, pre-operation temporal pacing and steroid use should be avoided if possible. Furthermore, COPD patients or those who accept CRTs should be monitored closely.

Background The correlation between severity and long-term outcomes of pediatric myocarditis have been reported, however this correlation in adults has rarely been studied.

Significance: Genetic markers in TRANK1 gene and its vicinity have been weakly associated with bipolar disorder and schizophrenia (10% increased risk). We found that the same polymorphisms are associated with Kleine-Levin syndrome (50% increased risk), a rare sleep disorder characterized by recurrent episodes of severe hypersomnia and cognitive abnormalities. Response to lithium treatment is suggestive of a pathophysiological overlap between KLS and bipolar disorder. The study also shows that variants in the TRANK1 gene region may predispose to KLS when patients have had a difficult birth, suggesting that TRANK1 gene region modulates newborns’ response to brain injury, with consequences for mental and neurological health in adulthood. Another possibility may be that the polymorphism impacts birth and KLS.
