background: Our aim was to study ways to improve IVF success rates in women with suspected endometrial receptivity defects. methods: We conducted a retrospective cohort study examining the effect of letrozole (aromatase inhibitor) on integrin expression as a marker of endometrial receptivity. We compared IVF outcomes in 97 infertile women who had undergone anb3 integrin assessment by immunohistochemistry in mid-luteal endometrial biopsies. Of 79 women undergoing standard IVF, 29 (36.7%) lacked normal integrin expression. Eighteen other women with low integrin were studied after receiving letrozole during early IVF stimulation. An independent set of anb3 integrin-negative patients (n ¼ 15) who had undergone repeat endometrial biopsy for integrin testing while taking letrozole were re-evaluated.results: Clinical pregnancy and delivery rates were higher in women with normal anb3 integrin expression compared with those who were integrin negative [20/50 (40%) versus 4/29 (13.8%); P ¼ 0.02 and 19/50 (38%) versus 2/29 (7%); P , 0.01, respectively]. In 18 women who received letrozole early in IVF, 11 conceived (61.1%; P , 0.001) compared with integrin-negative patients who did not receive letrozole. In integrin-negative women who were rebiopsied on letrozole, 66.7% reverted to normal integrin expression. Positive endometrial aromatase immunostaining using a polyclonal antibody was a common finding in infertile patients compared with controls.conclusions: Lack of endometrial anb3 integrin expression is associated with a poor prognosis for IVF that might be improved with letrozole co-treatment. Prospective studies are needed to confirm and extend these findings but the data suggest that aromatase expression may contribute to implantation failure in some women.

The majority of case reports with NDM-1-producing bacteria had presumed colonization, not infection, with one or more bacteria. The available human case reports and surveillance data suggest a global distribution of NDM-1-producing Enterobacteriaceae and non-Enterobacteriaceae.

Asthma-chronic obstructive pulmonary disease overlap syndrome (ACOS) is a loosely-defined clinical entity referring to patients who exhibit characteristics of both asthma and chronic obstructive pulmonary disease (COPD). Clinical definitions and classifications for ACOS vary widely, which impacts our understanding of prevalence, diagnosis and treatment of the condition. This literature review was therefore conducted to characterize the prevalence of ACOS and the effect of different disease definitions on these estimates, as this has not previously been explored. From an analysis of English language literature published from 2000 to 2014, the estimated prevalence of ACOS ranges from 12.1% to 55.2% among patients with COPD and 13.3%-61.0% among patients with asthma alone. This variability is linked to differences in COPD and asthma diagnostic criteria, disease ascertainment methods (spirometry-based versus clinical or symptom-based diagnoses and claims data), and population characteristics including age, gender and smoking. Understanding the reasons for differences in prevalence estimates of ACOS across the literature may help guide decision making on the most appropriate criteria for defining ACOS and aid investigators in designing future ACOS clinical studies aimed at effective treatment.

One-tenth of antidepressant initiators with depression simultaneously initiated benzodiazepine therapy. No meaningful difference in antidepressant treatment at 6 months was observed by simultaneous new use status. Because of the risks associated with benzodiazepines, simultaneous new use at antidepressant initiation and the benzodiazepine regimen itself require careful consideration.

The findings indicate several possible infectious disease syndemics in New York City and highlight the need to integrate surveillance data from different infectious disease programs. Conducting the match brought surveillance programs together to work collaboratively and has resulted in ongoing partnerships on programmatic activities that address multiple diseases.

Objective Prior research evaluated various effects of the antidepressant black-box warning on the risk of suicidality in children, but the dosing of antidepressants has not been considered. This study estimated, relative to the FDA warnings, whether the initial antidepressant dose prescribed decreased and the proportion augmenting dose on the second fill increased. Method The study utilized the LifeLink Health Plan Claims Database. The study cohort consisted of commercially insured children (5–17 years), young adults (18–24 years), and adults (25–64 years) initiating an SSRI (citalopram, fluoxetine, paroxetine, or sertraline) from 1/1/2000 to 12/31/2009. Dose-per-day was determined by days supply, strength, and quantity dispensed. Initiation on low dose, defined based on guidelines, and dose augmentations (dose increase >1mg/day) on the second prescription were considered across time periods related to the antidepressant warnings. Results Of 51,948 children who initiated an SSRI, 15% initiated on low dose in the period before the 2004 black-box warning and 31% in the period after the warning (a 16 percentage-point change); there was a smaller percentage-point change in young adults (6%) and adults (3%). The overall increase in dose augmentations in children and young adults was driven by the increase in patients initiating on a low dose. Conclusions As guidelines recommend children initiate antidepressant treatment on low dose, findings that an increased proportion of commercially insured children initiated an SSRI on low dose after the 2004 black-box warning suggest prescribing practices surrounding SSRI dosing improved in children following the warning but dosing practices still fall short of guidelines.
