Background
This study assessed the extent to which women's preconception binge drinking, tobacco use and cannabis use, reported prospectively in adolescence and young adulthood, predicted use of these substances during pregnancy and at 1 year postpartum.
MethodsData were pooled from two intergenerational cohort studies: the Australian Temperament Project Generation 3 Study (395 mothers, 691 pregnancies) and the Victorian Intergenerational Health Cohort Study (398 mothers, 609 pregnancies). Alcohol, tobacco and cannabis use were assessed in adolescence (13–18 years), young adulthood (19–29 years) and at ages 29–35 years for those transitioning to parenthood. Exposures were weekly or more frequent preconception binge drinking (5 + drinks in one session), tobacco use and cannabis use. Outcomes were any alcohol, tobacco and cannabis use prior to awareness of the pregnancy, after awareness of pregnancy (up to and including the third trimester pregnancy) and at 1 year postpartum.
ResultsFrequent preconception binge drinking, tobacco use and cannabis use across both adolescence and young adulthood were strong predictors of continued use post-conception, before and after awareness of the pregnancy and at 1 year postpartum. Substance use limited to young adulthood also predicted continued use post-conception.
ConclusionsPersistent alcohol, tobacco use and cannabis use that starts in adolescence has a strong continuity into parenthood. Reducing substance use in the perinatal period requires action well before pregnancy, commencing in adolescence and continuing into the years before conception and throughout the perinatal period.

This research paper addresses the effect of different grouping strategies of fresh cows on total lactational and reproductive performance. Hundred-sixty multiparous Holstein cows were enrolled in a completely randomized design and assigned to one of following treatments: 21 days in fresh pen with 12.5 kg/day concentrate (C21, n = 60), 10 days in fresh pen with 12.5 kg/day concentrate (C10, n = 50) and 10 days in fresh pen with 10 kg/day concentrate (L10, n = 50). Although there were no differences among treatments within the first 10 days in milk (DIM), C10 and L10 cows tended to produce more milk than C21 from 10 to 21 DIM. In addition, greater milk yield was obtained in C10 and L10 cows during 22–28 DIM and 29–70 DIM. Higher production in early lactation resulted in a tendency for greater milk production for C10 and L10 cows throughout a 305 days lactation. There was no difference in productivity between C10 and L10 groups at any time point. No blood metabolites (Ca, P, non-esterified fatty acids and β-hydroxy butyrate) were affected by treatments. Pregnancy at first, second and third service was 38, 39 and 40%, respectively, which were not influenced by the days in fresh pen or concentrate allowance. Collectively, our results for the first time suggest that fresh cow grouping strategy has a long-term effect on productivity but that adding 2.5 kg/day concentrate has no effect on milk yield in fresh pen.

Background:
Implementing antimicrobial stewardship programs (ASPs) can be challenging due to prescriber resistance. Although barriers to implementing new ASPs have been identified, little is known about how prescribers perceive established programs. This information is critical to promoting the sustainability of ASPs.
Objective:To identify how prescribers perceive an established pediatric inpatient ASP that primarily utilizes prior authorization.
Methods:We conducted a cross-sectional survey administered from February through June 2017 in a large children’s hospital. The survey contained closed- and open-ended questions. Descriptive statistics and thematic content analysis approaches were used to analyze responses.
Results:Of 394 prescribers invited, 160 (41%) responded. Prescribers had an overall favorable impression of the ASP, believing that it improves the quality of care (92.4% agree) and takes their judgment seriously (73.8%). The most common criticism of the ASP was that it threatened efficiency (26.0% agreed). In addition, 68.7% of respondents reported occasionally engaging in workarounds. Analysis of 133 free-text responses revealed that prescribers perceived that interacting with the ASP involved too many phone calls, caused communication breakdowns with the dispensing pharmacy, and led to gaps between approval and dispensing of antibiotics. Reasons given for workarounds included not wanting to change therapy that appears to be working, consultant disagreement with ASP recommendations, and the desire to do everything possible for patients.
Conclusions:Prescribers had a generally favorable opinion of an established ASP but found aspects to be inefficient. They reported engaging in workarounds occasionally for social and emotional reasons. Established ASPs should elicit feedback from frontline prescribers to optimize program impact.

Several sulfonylurea herbicides are labeled for use on established bermudagrass or seashore paspalum, but label recommendations for many of these chemicals vary for sprigged turf. The objective of this study was to determine the safety of various sulfonylurea herbicides on newly planted, ‘Tifway’ bermudagrass and ‘Aloha’ seashore paspalum sprigs in Arkansas and Louisiana. Treatments were arranged as a five by two by two factorial with five herbicides (foramsulfuron at 29 and 59 g ai ha−1, halosulfuron at 35 and 70 g ai ha−1, metsulfuron at 21 and 42 g ai ha−1, sulfosulfuron at 66 and 131 g ai ha−1, and trifloxysulfuron at 28 and 56 g ai ha−1), two herbicide rates (low and high), and two application timings at 2 or 4 wk after sprigging (WAS). There was no discernable herbicide injury to, or reduction in, Tifway bermudagrass coverage in Arkansas, regardless of herbicide, application timing, or application rate. Trifloxysulfuron and metsulfuron were more injurious than other herbicides in Louisiana when applied at 2 WAS to Tifway bermudagrass, but injury levels were acceptable (< 15%), and there was no long-term reduction in establishment. Metsulfuron or halosulfuron applied at 2 or 4 WAS and sulfosulfuron applied at 4 WAS allowed > 90% establishment of Aloha seashore paspalum at both locations. Both trifloxysulfuron and foramsulfuron were injurious to seashore paspalum and reduced its establishment. These results suggest that sulfonylurea herbicides can be safely applied shortly after sprigging to Tifway bermudagrass and that metsulfuron, halosulfuron, and sulfosulfuron could be useful herbicides for establishing Aloha seashore paspalum from sprigs.

Staphylococcus aureus is a relatively uncommon cause of community-onset pneumonia (COP) that may complicate influenza infection. We reviewed admissions to children's hospitals to describe more systematically this entity. Records of patients hospitalized at three children's hospitals between 1 October 2006 and 30 April 2007 who had a positive S. aureus culture from a sterile site or respiratory specimen were reviewed and data were abstracted for episodes of primary S. aureus COP. Overall, 30 episodes met criteria for primary S. aureus COP; 12 (41%) involved methicillin-resistant S. aureus. Patients in 11 (37%) episodes were seen by a healthcare provider for their symptoms prior to hospital admission; three received an antimicrobial, none of which had activity against the S. aureus isolated. Mechanical ventilation was required in 21 (70%) episodes; five (17%) patients died. When evaluating patients with severe COP, providers should be aware of the potential for S. aureus, including methicillin-resistant strains.

The objectives of the current study were to determine the degree to which space allocation in a deep-bedded system influences swine performance and pork quality. The deep-bedded method employed was hoop structures, which are large, tent-like shelters with cornstalks or straw for bedding. One hundred gilts ranging in weight from 59 to 71 kg were randomly assigned to treatments of low (0.70 m2 per pig, n = 50) or high (1.13 m2 per pig, n = 50) space allocation. During the 45-day experimental period, gilts were ad libitum fed a two-phase diet. Six gilts per treatment were used for carcass composition and pork quality evaluation for each replication. Five replications were conducted over a period of 4 months. Pigs finished with greater space allocation had smaller longissimus muscle area and produced pork that appeared to be darker. Variations in fatty acid composition and lipid percentage of subcutaneous adipose and longissimus dorsi muscle were observed when space allocation was changed within hoop structures. Less space resulted in greater proportion of lipid present as polyunsaturated fatty acids. Greater space allocation resulted in lower total lipid in subcutaneous pork adipose tissue. Space allocation did not affect fat firmness. Replications spanned the months of August to November, with temperatures ranging from 32°C to −2°C within the hoop structure. As environmental temperature declined, the proportion of monounsaturated fatty acids increased. Providing more space during finishing in these systems had only a small affect on pig growth and pork quality. Variations observed from replication to replication at fluctuating temperatures provide insight to seasonal differences in growth and adipose tissue composition and firmness. Therefore, finishing pigs in these systems may lead to seasonal variation in lipid composition.

The purpose of this study was to compare effects of finishing environment on growth performance, pork quality and lipid composition of pork. Environments compared were standard confinement (CON) and deep-bedded semi-outdoor systems. The deep-bedded method employed in the current study was the use of hoop structures. Hoops are large, tent-like shelters with cornstalks or straw for bedding. Gilts ranging in weight from 59 to 71 kg were randomly assigned to treatments of Hoop (n = 50) and CON (n = 18) environments. Gilts were fed a two-phase dietary sequence, ad libitum for 45 days. Six gilts per treatment were selected for carcass composition and quality evaluation. The experiment was replicated a total of five times. Pigs raised in the Hoop environment gained significantly less and required significantly more feed for growth than pigs raised in the CON environment. Carcasses from CON-finished pigs were significantly fatter at the 10th rib, which lowered carcass percentage fat-free lean(FFL) and they also had greater loin marbling scores compared with carcasses from Hoop-finished pigs (P < 0.05). Significant replication effects were noted on beginning weight, live weight, carcass weight, percentage FFL, backfat, lipid content and adipose firmness. Carcasses from Hoop pigs had lower proportions of palmitic acid (P < 0.05), and higher proportions of oleic and linoleic acid (P < 0.05) in the inner layer of adipose tissue. The proportion of saturated fatty acid was lower, and that of mono- and poly-unsaturated fatty acid was higher in the inner layer of the adipose tissue of Hoop pigs. Variations in fatty acid composition and lipid deposition may have been caused by environmental temperature, since decreases in environmental temperature accompanied compositional variation of the adipose, leading to higher proportions of monounsaturated fatty acid and lower proportions of saturated and polyunsaturated fatty acid in adipose tissue, regardless of treatment. Volatile profile analysis revealed that adipose tissue of Hoop pigs had significantly higher amounts of 3-butanal and heptanal compared with CON pigs, which may be related to the amount of oleic and linoleic acids composing the adipose tissue. These data indicate finishing pigs in hoop structures allows for exposure to fluctuating temperatures, which may influence the growth of pigs, as well as fatty acid composition and firmness of pork products.

Summary
In 1994, Mattel created a Barbie™ doll that said, “Math is hard.” The Barbie Liberation Organization, a group composed of activists and media personalities, among others, protested against Barbie's perpetuation of gender-based stereotyping. The media publicized the case and discussions on gender stereotyping in children's toys ensued on and off the air, leading Mattel to withdraw the “math is hard” Barbie from the market.
However, did Barbie's frustration with math represent a reality in which girls and women, more than boys and men, find math to be hard? Benbow and Stanley (1980, 1983) found gender differences in performance on the mathematical section of the SAT (SAT-M) in boys and girls under the age of fourteen who were high in math achievement. The boys outperformed the girls by about half a standard deviation and were overrepresented by a ratio of 13:1 among students who scored above 700. Similarly, in a meta-analysis involving over three million participants, Hyde, Fennema, and Lamon (1990) found a gender difference favoring males that emerged from high school (d = 0.29) through college (d = 0.41), and into adulthood (d = 0.59). Finally, Brown and Josephs (1999) reported that the two most widely used standardized tests of mathematics in the United States, the SAT-M and the quantitative portion of the GRE (GRE-Q), revealed a gender difference in the order of half a standard deviation.
This gender difference can also be seen in the types of activities that females vs. males tend to pursue.

Background. Reports of adolescent suicidal behaviour have generally derived from clinical settings but population-based studies are likely to provide a clearer epidemiological view.
Methods. Non-fatal suicidal behaviours were studied in 1699 Australian 15- to 16-year-old secondary school students at 44 schools in the state of Victoria, Australia. Self-reported episodes of self-harm were characterized using items from the Beck Suicide Intent Scale.
Results. The 12 month weighted prevalence estimate for deliberate self-harm was 5·1%. The commonest forms were self-laceration (1·7%), self-poisoning (1·5%) and deliberate recklessness (1·8%). Self-poisoning and self-laceration were commoner in girls. The prevalence of ‘true suicide attempts’ was 0·2%. Most self-harmers did not perceive death as likely, plan self-harming episodes at length or inform others of the episodes. Psychiatric morbidity had the strongest association with self-harm, an association which held for all subtypes. Antisocial behaviour and substance abuse were associated with self-harm in girls but not boys. Sexual activity was independently associated with self-harm in both genders.
Conclusions. Deliberate self-harm was common but the great majority of episodes were not ‘true suicide attempts’. It is, therefore, possible that attributable mortality and morbidity may be greater in self-harmers without definite suicidal intent.

Distribution of cesium and silver ion-exchanged onto columns of zeolites may be measured directly and non-destructively on the column with the use of radioisotope-excited energy dispersive X-ray fluorescence. Quantitative accounting of the exchanged metals is obtained without elution.
