PROBLEM: Context: Corticosteroids are a critical component of therapy for acute lymphoblastic leukemia (ALL) but are associated with late effects, such as osteoporosis. Risk factors remain poorly defined. Because CRHR1 polymorphisms have been associated with other corticosteroid effects, our goal was to define whether CRHR1 polymorphisms predict which patients with ALL are likely to develop bone mineral deficits.', 'The mean bone mineral density z scores of 309 long-term survivors of ALL were determined by quantitative computed tomography of the trabecular lumbar spine. We analyzed whether CRHR1 genotypes, adjusted for sex, ALL treatment regimen, and weight, could predict bone density.', 'We found that three single nucleotide polymorphisms (SNPs), all in linkage disequilibrium, were associated with bone density in a sex-specific manner. Bone density was lower in males (P = .001), in nonblack patients (P < .08), in those who were not overweight (P < .001), and in those who received intensive antimetabolites and glucocorticoids (P < .001). After adjustment for these features, the G allele at the rs1876828 SNP was associated with lower z scores (P = .02) in males but tended to have the opposite association in females (P = .09).
Answer: CRHR1 polymorphisms may impact the risk of bone density deficits in patients treated with corticosteroids and antimetabolites in a sex-specific manner.

SOLUTION: Do cRHR1 polymorphisms predict bone density in survivors of acute lymphoblastic leukemia?

PROBLEM: Context: High sensitivity C-reactive protein (hsCRP) is more sensitive than standard C-reactive protein (CRP) assay in evaluating the risk of coronary heart disease and other atherosclerotic events. By this time, there are several reports that type 2 diabetic subjects have higher serum levels of hsCRP than those of non-diabetic subjects. However, there are few reports about factors which have influence upon the level of serum hsCRP in type 2 diabetic subjects. We had evaluated the association of serum hsCRP level with risk factors of cardiovascular diseases and carotid intima-media thickness (IMT) in type 2 diabetic subjects.', 'One hundred and five patients (59 men and 46 women) with type 2 diabetes were recruited. Subjects with severe cardiovascular diseases were excluded. All subjects were undergone carotid ultrasonography for evaluation of carotid IMT. Serum hsCRP concentrations were measured.', 'Serum hsCRP level was correlated with mean left IMT (r = 0.366, P = 0.003), maximal left IMT (r = 0.370, P = 0.002), mean right IMT (r = 0.281, P = 0.023) and maximal right IMT (r = 0.370, P = 0.002), body mass index (r = 0.377, P < 0.001), waist circumference (r = 0.342, P < 0.001), waist-hip ratio (r = 0.229, P = 0.020), serum total cholesterol (r = 0.202, P = 0.024), serum triglyceride (r = 0.292, P = 0.022) and serum low-density lipoprotein (r = 0.133, P = 0.044).
Answer: Our result shows that serum hsCRP level is correlated with carotid IMT and the risk factors of cardiovascular diseases and may be useful to predict accelerated atherosclerotic process in type 2 diabetic subjects.

SOLUTION: Is serum high sensitivity C-reactive protein associated with carotid intima-media thickness in type 2 diabetes?

PROBLEM: Context: Lower respiratory tract infection is a common cause of consultation and antibiotic prescription in paediatric practice. The misuse of antibiotics is a major cause of the emergence of multidrug-resistant bacteria. The aim of this study was to evaluate the frequency, changes over time, and determinants of non-compliance with antibiotic prescription recommendations for children admitted in paediatric emergency department (PED) with community-acquired pneumonia (CAP).', 'We conducted a prospective two-period study using data from the French pneumonia network that included all children with CAP, aged one month to 15\xa0years old, admitted to one of the ten participating paediatric emergency departments. In the first period, data from children included in all ten centres were analysed. In the second period, we analysed children in three centers for which we collected additional data. Two experts assessed compliance with the current French recommendations. Independent determinants of non-compliance were evaluated using a logistic regression model. The frequency of non-compliance was compared between the two periods for the same centres in univariate analysis, after adjustment for confounding factors.', 'A total of 3034 children were included during the first period (from May 2009 to May 2011) and 293 in the second period (from January to July 2012). Median ages were 3.0\xa0years [1.4-5] in the first period and 3.6\xa0years in the second period. The main reasons for non-compliance were the improper use of broad-spectrum antibiotics or combinations of antibiotics. Factors that were independently associated with non-compliance with recommendations were younger age, presence of risk factors for pneumococcal infection, and hospitalization. We also observed significant differences in compliance between the treatment centres during the first period. The frequency of non-compliance significantly decreased from 48 to 18.8\xa0% between 2009 and 2012. The association between period and non-compliance remained statistically significant after adjustment for confounding factors. Amoxicillin was prescribed as the sole therapy significantly more frequently in the second period (71\xa0% vs. 54.2\xa0%, p\u2009<\u20090.001).
Answer: We observed a significant increase in the compliance with recommendations, with a reduction in the prescription of broad-spectrum antibiotics, efforts to improve antibiotic prescriptions must continue.

SOLUTION:
Is compliance with the current recommendations for prescribing antibiotics for paediatric community-acquired pneumonia improving : data from a prospective study in a French network?
