[Q]: Context: Studies that investigate the subjective benefit from a bone conduction implant (BCI) sound processor in patients with single-sided sensorineural deafness (SSD) have been limited to examining short- and mid-term benefit. In the current study, we performed a survey among 44 SSD BCI users with a median follow-up time of 50 months.', 'Forty-four experienced SSD BCI users participated in the survey, which consisted of the Abbreviated Profile of Hearing Aid Benefit, the Single-Sided Deafness Questionnaire, the Short Hearing Handicap Inventory for Adults, and a self-made user questionnaire. For patients with tinnitus, the Tinnitus Questionnaire was also completed. The results of the survey were correlated with contralateral hearing loss, age at implantation, duration of the hearing loss at the time of implantation, duration of BCI use, and the presence and burden of tinnitus.', 'In total, 86% of the patients still used their sound processor. The Abbreviated Profile of Hearing Aid Benefit and the Short Hearing Handicap Inventory for Adults show a statistically significant overall improvement with the BCI. The Single-Sided Deafness Questionnaire and the user questionnaire showed that almost 40% of the patients reported daily use of the sound processor. However, the survey of daily use reveals benefit only in certain circumstances. Speech understanding in noisy situations is rated rather low, and 58% of all patients reported that their BCI benefit was less than expected.
Answer: The majority of the patients reported an overall improvement from using their BCI. However, the number of users decreases during a longer follow-up time and patients get less enthusiastic about the device after an extended period of use, especially in noisy situations. However, diminished satisfaction because of time-related reductions in processor function could not be ruled out.
[A]: Do long-term subjective benefit with a bone conduction implant sound processor in 44 patients with single-sided deafness?

[Q]: Context: Previous studies have suggested that post-irradiation GH insufficiency results from a loss of GHRH secretion, since many patients were able to release GH following exogenous GHRH stimulation. However, supramaximal doses of GHRH were used and the response may decline with time after radiotherapy. We re-evaluated the GHRH dose-response curve in patients post cranial irradiation and in controls.', 'Randomized controlled study.', 'Five adult male long-term survivors of childhood brain tumours (median age 21.8 years (18.4-26.7); 13.7 years (11.4-15.7) post-radiotherapy, >30Gy) and five matched controls were studied. An intravenous bolus of GHRH(1-29)NH(2) was administered in doses at the lower (0.05 microg/kg) and upper (0.15 microg/kg) range of the dose-response curves for young males, as well as the standard supramaximal dose (1. 0 microg/kg). GH was measured before stimulation, every 2min for the first hour and every 5min for the second hour. All studies were conducted in a random fashion.', 'Significantly lower peak and area under the curve (AUC) GH concentrations occurred in the irradiated group using 0.15 microg/kg (median peak Irradiated, 4. 5mU/l vs median Controls, 37.4mU/l; P<0.01) and 1.0 microg/kg (median peak Irradiated, 4.8mU/l vs median Controls, 15.2mU/l; P<0. 05) GHRH(1-29)NH(2). In irradiated subjects there was an incremental rise in GH output with increasing doses of GHRH(1-29)NH(2 )(median AUC: 122mU/l.min vs 179mU/l.min vs 268mU/l.min; P=0.007) reflecting altered pituitary sensitivity and reduced responsiveness.
Answer: The GH response to bolus GHRH(1-29)NH(2) is attenuated in adult long-term survivors of childhood brain tumours. This may reflect direct pituitary damage and/or the loss of the tropic effects of chronic GHRH deficiency.
[A]: Is the GH response to low-dose bolus growth hormone-releasing hormone ( GHRH ( 1-29 ) NH2 ) attenuated in patients with longstanding post-irradiation GH insufficiency?

[Q]: Context: The Affordable Care Act (ACA) Medicaid expansion varies in availability across states.', 'We compared characteristics of low-income uninsured residents in both Medicaid nonexpanding and expanding states with respect to their dietary quality, health risk factors, and access to care.', 'Data from the 2007-2012 National Health and Nutrition Examination Survey was matched with the Kaiser Family Foundation Medicaid expansion data. Bivariate and multivariate regressions were estimated to assess differences across expanding and non-expanding states.', 'The non-expansion group had a lower Healthy Eating Index score (41.8 vs. 44.1, p-value=0.006), a higher Body Mass Index (29.9 vs. 28.9, p-value=0.032), higher obesity prevalence (41% vs. 33%, p-value=0.007), and lower asthma prevalence (14.8% vs. 19.7%, p-value=0.037) compared with the expansion group.
Answer: Differences across states in Medicaid coverage under the ACA may lead to widening disparities in health outcomes between expanding and non-expanding states.
