Renee Moore questions the wisdom of the the idea—raised in recent days by both Bill Gates and U.S. Secretary of Education Arne Duncan—of paying effective teachers more for taking on larger class sizes: Giving the most effective teachers larger classes is NOT a way to reward them, but it is a way to

Keeping preschool class sizes at or under 20 children, and keeping child-teacher ratios at 10 to 1, will work for most children in preschool, according to a new study.

Class size does matter for teachers and students, but only if the instruction used in the small class size is different from those instructional practices used in a large one.

Only very large reductions in class size are likely to lead to significant long-term effects on student achievement, a new research synthesis says.

Continuing increases in K-12 enrollment, a downturn in higher education enrollment, and a rise in cyberbullying are among the trends illustrated in two new statistical publications from the U.S. Department of Education.

If class sizes aren't going to be addressed because of bottom lines, either because of a lack of teacher resources or school funding, then we are going to have to find a way to function better inside of these undesirable situations.

Smaller classes could help bridge the gap between home and school, writes former teacher Marc Vincenti.

Percentile charts for birth weight are used to assess the somatic development of neonates (small, appropriate, or large for gestational age).

A systematic error was identified in the majority of birth weight percentile charts. As a consequence, small for gestational age rates are overestimated and large for gestational age rates are underestimated; ~5% of neonates are misclassified. (Read the full article)

Many US children aged 6 to 24 months who would be classified as low weight-for-age by the Centers for Disease Control and Prevention 2000 reference will be classified as normal weight-for-age by the World Health Organization 2006 standard.

Children who will be reclassified from low to normal weight-for-age using the World Health Organization growth standard are at higher risk of adverse health outcomes than children who are not low weight-for-age by the Centers for Disease Control and Prevention reference. (Read the full article)

The majority of youth are not meeting the recommended physical activity guidelines. Dance classes are popular for girls and have potential to provide physical activity for many youth. Little is known about how active youth are in different dance types.

Objectively measured physical activity in dance classes are low and generally provide less physical activity than youth sports. There is a public health imperative to engage the dance profession in efforts to improve the health impact of youth dance classes. (Read the full article)

β-lactam resistance in Staphylococcus aureus limits treatment options. Stp1 and Stk1, a serine-threonine phosphatase and kinase respectively, mediate serine-threonine kinase (STK) signaling. Loss of function point mutations in stp1 were detected among laboratory passaged, β-lactam resistant S. aureus strains lacking mecA and blaZ, the major determinants of β-lactam resistance in the bacteria. Loss of Stp1 function facilitates β-lactam resistance of the bacteria.

Ibrexafungerp (formerly SCY-078) is a semisynthetic triterpenoid and potent (1->3)-β-D-glucan synthase inhibitor. We investigated the in vitro activity, pharmacokinetics, and in vivo efficacy of ibrexafungerp (SCY) alone and in combination with anti-mould triazole isavuconazole (ISA) against invasive pulmonary aspergillosis (IPA). The combination of ibrexafungerp and isavuconazole in in vitro studies resulted in an additive and synergistic interactions against Aspergillus spp. Plasma concentration-time curves of ibrexafungerp were compatible with linear dose proportional profile. In vivo efficacy was studied in a well established persistently neutropenic NZW rabbit model of experimental IPA. Treatment groups included untreated rabbits (UC) and rabbits receiving ibrexafungerp at 2.5(SCY2.5) and 7.5(SCY7.5) mg/kg/day, isavuconazole at 40(ISA40) mg/kg/day, or combinations of SCY2.5+ISA40 and SCY7.5+ISA40. The combination of SCY+ISA produced in vitro synergistic interaction. There was significant in vivo reduction of residual fungal burden, lung weights, and pulmonary infarct scores in SCY2.5+ISA40, SCY7.5+ISA40, and ISA40-treatment groups vs that of SCY2.5-treated, SCY7.5-treated and UC (p<0.01). Rabbits treated with SCY2.5+ISA40 and SCY7.5+ISA40 had prolonged survival in comparison to that of SCY2.5-, SCY7.5-, ISA40-treated or UC (p<0.05). Serum GMI and (1->3)-β-D-glucan levels significantly declined in animals treated with the combination of SCY7.5+ISA40 in comparison to those treated with SCY7.5 or ISA40 (p<0.05). Ibrexafungerp and isavuconazole combination demonstrated prolonged survival, decreased pulmonary injury, reduced residual fungal burden, lower GMI and (1->3)-β-D-glucan levels in comparison to those of single therapy for treatment of IPA. These findings provide an experimental foundation for clinical evaluation of the combination of ibrexafungerp and an anti-mould triazole for treatment of IPA.

Despite the worldwide re-emergence of the chikungunya virus (CHIKV) and the high morbidity associated with CHIKV infections, there is no approved vaccine or antiviral treatment available. We here aim to identify the target of a novel class of CHIKV inhibitors i.e. CHVB series. CHVB compounds inhibit the in vitro replication of CHIKV isolates with 50% effective concentrations in the low micromolar range. A CHVB-resistant variant (CHVB^res) was selected that carried two mutations in the gene encoding nsP1 (responsible for viral RNA capping), one mutation in nsP2 and one mutation in nsP3. Reverse genetics studies demonstrated that both nsP1 mutations were necessary and sufficient to achieve ~18-fold resistance, suggesting that CHVB targets viral mRNA capping. Interestingly, CHVB^res was cross-resistant to the previously described CHIKV capping inhibitors from the MADTP series, suggesting they share a similar mechanism of action. In enzymatic assays, CHVB inhibited the methyltransferase and guanylyltransferase activities of alphavirus nsP1 proteins. To conclude, we identified a class of CHIKV inhibitors that targets the viral capping machinery. The potent anti-CHIKV activity makes this chemical scaffold a potential candidate for CHIKV drug development.
