Objective
To examine the use of vitamin D supplements during infancy among the participants in an international infant feeding trial.
DesignLongitudinal study.
SettingInformation about vitamin D supplementation was collected through a validated FFQ at the age of 2 weeks and monthly between the ages of 1 month and 6 months.
SubjectsInfants (n 2159) with a biological family member affected by type 1 diabetes and with increased human leucocyte antigen-conferred susceptibility to type 1 diabetes from twelve European countries, the USA, Canada and Australia.
ResultsDaily use of vitamin D supplements was common during the first 6 months of life in Northern and Central Europe (>80 % of the infants), with somewhat lower rates observed in Southern Europe (>60 %). In Canada, vitamin D supplementation was more common among exclusively breast-fed than other infants (e.g. 71 % v. 44 % at 6 months of age). Less than 2 % of infants in the USA and Australia received any vitamin D supplementation. Higher gestational age, older maternal age and longer maternal education were study-wide associated with greater use of vitamin D supplements.
ConclusionsMost of the infants received vitamin D supplements during the first 6 months of life in the European countries, whereas in Canada only half and in the USA and Australia very few were given supplementation.

Objective.
To determine the prevalence of Acinetobacter baumannii, an important healthcare-associated pathogen, among mechanically ventilated patients in Maryland.
Design.The Maryland MDRO Prevention Collaborative performed a statewide cross-sectional active surveillance survey of mechanically ventilated patients residing in acute care and long-term care (LTC) facilities. Surveillance cultures (sputum and perianal) were obtained from all mechanically ventilated inpatients at participating facilities during a 2-week period.
Setting.All healthcare facilities in Maryland that provide care for mechanically ventilated patients were invited to participate.
Patients.Mechanically ventilated patients, known to be at high risk for colonization and infection with A. baumannii, were included.
Results.Seventy percent (40/57) of all eligible healthcare facilities participated in the survey, representing both acute care (n = 30) and LTC (n = 10) facilities in all geographic regions of Maryland. Surveillance cultures were obtained from 92% (358/390) of eligible Patients. A. baumannii was identified in 34% of all mechanically ventilated patients in Maryland; multidrug-resistant A. baumannii was found in 27% of all Patients. A. baumannii was detected in at least 1 patient in 49% of participating facilities; 100% of LTC facilities had at least 1 patient with A. baumannii, compared with 31% of acute care facilities. A. baumannii was identified from all facilities in which 10 or more patients were sampled.
Conclusions.A. baumannii is common among mechanically ventilated patients in both acute care and LTC facilities throughout Maryland, with a high proportion of isolates demonstrating multidrug resistance.

The activity patterns and changes in shape of schistosomula recovered from various locations during migration, are described. There is no significant increase in length during the period which worms remain in the skin. Rhythmic cycles of extension and contraction of the worm body are established soon after penetration. Worms newly arrived at the lungs are identical with skin worms of the same age. Within the lungs their maximum length increases to four times that of skin worms, an adaptation which is believed to facilitate migration through the lumina of blood capillaries. Worms recovered from the lungs and systemic organs on, and subsequent to, day 8 post-infection retain this capacity for elongation. When worms arrive at the hepatic portal system they undergo a process of shortening and there is a transient doubling in the duration of cycles of activity. It is suggested that this shape and activity change terminates migration by preventing escape of worms from the hepatic portal system via the liver sinuses. The stimulus which triggers the response is thought to be the high nutrient levels present in hepatic portal blood, but not in peripheral blood. The stimulus which terminates migration also probably initiates growth. Worms cultured in vitro undergo some increase in length, but have a significantly lower maximum length than lung worms of a corresponding age. Although cultured worms were active, the cycles of extension and contraction were much more erratic than those of in vivo worms. The worms shortened spontaneously after 8–10 days in culture. This shortening occurred marginally later than in the most rapidly migrating worms in vivo.
