Molecular Genetics of FAM161A in North American Patients with Early-Onset Retinitis Pigmentosa.

Retinitis pigmentosa (RP) is a hereditary disease that leads to the progressive degeneration of retinal photoreceptor cells and to blindness. It is caused by mutations in several distinct genes, including the ciliary gene FAM161A, which is associated with a recessive form of this disorder. Recent investigations have revealed that defects in FAM161A represent a rather prevalent cause of hereditary blindness in Israel and the Palestinian territories, whereas they seem to be rarely present within patients from Germany. Genetic or clinical data are currently not available for other countries. In this work, we screened a cohort of patients with recessive RP from North America to determine the frequency of FAM161A mutations in this ethnically-mixed population and to assess the phenotype of positive cases. Out of 273 unrelated patients, only 3 subjects had defects in FAM161A. A fourth positive patient, the sister of one of these index cases, was also identified following pedigree analysis. They were all homozygous for the p.T452Sfx3 mutation, which was previously reported as a founder DNA variant in the Israeli and Palestinian populations. Analysis of cultured lymphoblasts from patients revealed that mutant FAM161A transcripts were actively degraded by nonsense-mediated mRNA decay. Electroretinographic testing showed 30 Hz cone flicker responses in the range of 0.10 to 0.60 microvolts in all cases at their first visit (age 12 to 23) (lower norm  =  50 μV) and of 0.06 to 0.32 microvolts at their most recent examination (age 27 to 43), revealing an early-onset of this progressive disease. Our data indicate that mutations in FAM161A are responsible for 1% of recessive RP cases in North America, similar to the prevalence detected in Germany and unlike the data from Israel and the Palestinian territories. We also show that, at the molecular level, the disease is likely caused by FAM161A protein deficiency.

Parents' willingness to pay for diminishing children's pain during blood sampling.

BACKGROUND: Blood sampling is a frequent medical procedure, very often considered as a stressful experience by children. Local anesthetics have been developed, but are expensive and not reimbursed by insurance companies in our country. We wanted to assess parents' willingness to pay (WTP) for this kind of drug. PATIENTS AND METHODS: Over 6 months, all parents of children presenting for general (GV) or specialized visit (SV) with blood sampling. WTP was assessed through three scenarios [avoiding blood sampling (ABS), using the drug on prescription (PD), or over the counter (OTC)], with a payment card system randomized to ascending or descending order of prices (AO or DO). RESULTS: Fifty-six responses were collected (34 GV, 22 SV, 27 AO and 29 DO), response rate 40%. Response distribution was wide, with median WTP of 40 for ABS, 25 for PD, 10 for OTC, which is close to the drug's real price. Responses were similar for GV and SV. Median WTP amounted to 0.71, 0.67, 0.20% of respondents' monthly income for the three scenarios, respectively, with a maximum at 10%. CONCLUSIONS: Assessing parents' WTP in an outpatient setting is difficult, with wide result distribution, but median WTP is close to the real drug price. This finding could be used to promote insurance coverage for this drug.

Concurrent or Sequential Adjuvant Hormonoradiotherapy after Conservative Surgery for Early-Stage Breast Cancer: Clinical Results of the CO-HO-RT Phase II Randomized Trial.

Purpose: Letrozole (LET) has recently been shown to be superior to tamoxifen for postmenopausal patients (pts). In addition, LET radiosensitizes breast cancer cells in vitro. We conducted a phase II randomized study to evaluate concurrent and sequential radiotherapy (RT)-LET in the adjuvant setting. We present here clinical results with a minimum follow-up of 24 months. Patients and Methods: Postmenopausal pts with early-stage breast cancer were randomized after conservative surgery to either: A) concurrent RT-LET (LET started 3 weeks before the first day of RT) or B) sequential RT-LET (LET started 3 weeks after the end of RT). Whole breast RT was delivered to a total dose of 50 Gy. A 10-16 Gy boost was allowed according to age and pathological prognostic factors. Pts were stratified by center, adjuvant chemotherapy, boost, and radiation-induced CD8 apoptosis (RILA). RILA was performed before RT as previously published (Ozsahin et al. Clin Cancer Res, 2005). An independent monitoring committee reviewed individual safety data. Skin toxicities were evaluated by two different clinicians at each medical visit (CTCAE v3.0). Lung CT-scan and functional pulmonary tests were performed regularly. DNA samples were screened for SNPs in candidate genes as recently published (Azria et al., Clin Cancer Res, 2008). Results: A total of 150 pts were randomized between 01/05 and 02/07. Median follow-up is 26 months (range, 3-40 months). No statistical differences were identified between the two arms in terms of mean age; initial TNM; median surgical bed volume; post surgical breast volume. Chemotherapy and RT boost were delivered in 19% and 38% of pts, respectively. Nodes received 50 Gy in 23% of patients without differences between both arms. During RT and within the first 6 weeks after RT, 10 patients (6.7%) presented grade 3 acute skin dermatitis during RT but no differences were observed between both arms (4 and 6 patients in arm A and B, respectively). At 26 month of follow-up, grade 2 and more radiation-induced subcutaneous fibrosis (RISCF) was present in 4 patients (3%) without any difference between arm A (n = 2) and B (n = 2), p=0.93. In both arms, all patients that presented a RICSF had a RILA lower than 16%. Sensitivity and specificity were 100% and 39%, respectively.No acute lung toxicities were observed and quality of life was good to excellent for all patients.SNPs analyses are still on-going (Pr Rosenstein, NY). Conclusion: Acute and early late grade 2 dermatitis were similar in both arms. The only factor that influenced RISCF was a low radiation-induced lymphocyte apoptosis yield. We confirmed prospectively the capacity of RILA for identifying hypersensitive patients to radiation. Indeed, patients with RILA superior to 16% did not present late effects to radiation and confirmed the first prospective trial we published in 2005 (Ozsahin et al., Clin Cancer Res).

Unsatisfactory outcomes in myasthenia gravis: influence by care providers.

Myasthenia gravis (MG) can be difficult to treat despite an available therapeutic armamentarium. Our aim was to analyze the factors leading to unsatisfactory outcome (UO). To this end we used the Myasthenia Gravis Foundation of America classification system. Forty one patients with autoimmune MG were followed prospectively from January 2003 to December 2007. Outcomes were assessed throughout follow-up and at a final visit. 'Unchanged', 'worse', 'exacerbation' and 'died of MG' post-intervention status were considered UOs. During follow-up, UO rates reached 54% and were related to undertreatment (41%), poor treatment compliance (23%), infections (23%), and adverse drug effects (13%). The UO rate at final study assessment was 20%. UO during follow-up was significantly (P = 0.004) predictive of UOs at final assessment. When care was provided by neuromuscular (NM) specialists, patients had significantly better follow-up scores (P = 0.01). At final assessment UO rates were 7% and significantly better in patients treated by NM specialists, compared to other physicians where UO rates reached 27%. UO was a frequent finding occurring in more than half our patients during follow-up. Nearly two-thirds of the UOs could have been prevented by appropriate therapeutic adjustments and improved compliance. The differential UO rates at follow-up, their dependency on the degree to which the management was specialized and their correlation with final outcomes suggest that specialized MG care improves outcomes.

Can routine offering of influenza vaccination in office-based settings reduce racial and ethnic disparities in adult influenza vaccination?

BACKGROUND: Influenza vaccination remains below the federally targeted levels outlined in Healthy People 2020. Compared to non-Hispanic whites, racial and ethnic minorities are less likely to be vaccinated for influenza, despite being at increased risk for influenza-related complications and death. Also, vaccinated minorities are more likely to receive influenza vaccinations in office-based settings and less likely to use non-medical vaccination locations compared to non-Hispanic white vaccine users. OBJECTIVE: To assess the number of "missed opportunities" for influenza vaccination in office-based settings by race and ethnicity and the magnitude of potential vaccine uptake and reductions in racial and ethnic disparities in influenza vaccination if these "missed opportunities" were eliminated. DESIGN: National cross-sectional Internet survey administered between March 4 and March 14, 2010 in the United States. PARTICIPANTS: Non-Hispanic black, Hispanic and non-Hispanic white adults living in the United States (N = 3,418). MAIN MEASURES: We collected data on influenza vaccination, frequency and timing of healthcare visits, and self-reported compliance with a potential provider recommendation for vaccination during the 2009-2010 influenza season. "Missed opportunities" for seasonal influenza vaccination in office-based settings were defined as the number of unvaccinated respondents who reported at least one healthcare visit in the Fall and Winter of 2009-2010 and indicated their willingness to get vaccinated if a healthcare provider strongly recommended it. "Potential vaccine uptake" was defined as the sum of actual vaccine uptake and "missed opportunities." KEY RESULTS: The frequency of "missed opportunities" for influenza vaccination in office-based settings was significantly higher among racial and ethnic minorities than non-Hispanic whites. Eliminating these "missed opportunities" could have cut racial and ethnic disparities in influenza vaccination by roughly one half. CONCLUSIONS: Improved office-based practices regarding influenza vaccination could significantly impact Healthy People 2020 goals by increasing influenza vaccine uptake and reducing corresponding racial and ethnic disparities.

Recycling universe

If the effective cosmological constant is nonzero, our observable universe may enter a stage of exponential expansion. In such a case, regions of it may tunnel back to the false vacuum of an inflaton scalar field, and inflation with a high expansion rate may resume in those regions. An ideal eternal observer would then witness an infinite succession of cycles from false vacuum to true, and back. Within each cycle, the entire history of a hot universe would be replayed. If there were several minima of the inflaton potential, our ideal observer would visit each one of these minima with a frequency which depends on the shape of the potential. We generalize the formalism of stochastic inflation to analyze the global structure of the universe when this recycling process is taken into account.

Medicaid Value Management Program SFY 2008 Report Executive Summary, 2007

In June, 2007, the Commonwealth Fund released a report entitled, “Aiming Higher: Results from a State Scorecard on Health System Performance.” The report ranked states’ health care performance based upon four areas: access, quality, potentially avoidable use of hospitals and costs of care, and healthy lives. Iowa was ranked second overall and was the only state to rank in the top 25 percent on each of the four measures.1 Coupling the HEDIS measures and CAHPS survey results with the Commonwealth report outcomes provides additional information for determining how the state performs with regard to the health care system, in general, and the Medicaid program specifically. For the past five years the results of eight outcome measures encompassing children and adults, and preventive, chronic and acute care have been reported by the University of Iowa Public Policy Center (PPC). The PPC is the independent evaluator for the Medicaid managed care programs and assists the state in an effort to understand the process of care within the Medicaid program. Seven of the eight measures are recommended by the Centers for Medicare and Medicaid, while the eighth, annual dental visit, is used in recognition of the challenges found in providing dental care to Medicaid‐enrolled children and adults.

High-altitude exposure in patients with cardiovascular disease: risk assessment and practical recommendations.

Because of the development of modern transportation facilities, an ever rising number of individuals including many patients with preexisting diseases visit high-altitude locations (>2500 m). High-altitude exposure triggers a series of physiologic responses intended to maintain an adequate tissue oxygenation. Even in normal subjects, there is enormous interindividual variability in these responses that may be further amplified by environmental factors such as cold temperature, low humidity, exercise, and stress. These adaptive mechanisms, although generally tolerated by most healthy subjects, may induce major problems in patients with preexisting cardiovascular diseases in which the functional reserves are already limited. Preexposure assessment of patients helps to minimize risk and detect contraindications to high-altitude exposure. Moreover, the great variability and nonpredictability of the adaptive response should encourage physicians counseling such patients to adapt a cautionary approach. Here, we will briefly review how high-altitude adjustments may interfere with and aggravate/decompensate preexisting cardiovascular diseases. Moreover, we will provide practical recommendations on how to investigate and counsel patients with cardiovascular disease desiring to travel to high-altitude locations.

Chronically connected? Internet use among adolescents with chronic conditions.

Little is known about Internet use among adolescents with chronic conditions (CCs). Our results indicate that CC females, but not males, are more likely to be heavy Internet users than their peers. CC youths are also more likely to visit health-related web sites, but less frequently than other sites.

Retrospective analysis of complications of immunosuppressive therapies (steroidsand immunosuppressive therapies) in pediatric uveitis

Purpose¦The purpose of this study is to analyze the incidence rate of side effects occurring during systemic therapy (corticosteroids, methotrexate, azathioprine, cyclosporine A or biologic agents) of auto-immune uveitis.¦Material and methods¦Retrospective study including 23 / 71 patients aged between 0-16 years old presenting with a chronic non-infectious uveitis. All children were treated in the Jules-Gonin Eye Hospital and paediatric rheumatology unit of the CHUV (Centre Hospitalier Universitaire Vaudois) between January 2000 and December 31st 2010. Side effects were reported as minor (without subsequent change in systemic medication), moderate (associated with a change in systemic dosage or class of immunosuppressive therapy or in the presence of Cushingoid face or weight gain) or severe (hospitalization or life threatening).¦Results¦52% of boys and 48% of girls are present in the cohort with a mean age at the first visit of 8.1 years (1.7-15.6). Intermediate uveitis consisted of the commonest aetiology with 8 patients (35%), juvenile idiopathic arthritis (JIA) in 7 (30%), Behçet's disease in 3 (13%) and others in 5 (22%). The overall length of therapy was longer for prednisone (26.6 ± 5.4 patient / year), but was similar between methotrexate (22.1 ± 5.4 patient / year) and azathioprine (15.2 patient / year). Moderate side effects were respectively 64% for corticosteroids therapy, 54% with methotrexate and 14% with azathioprine. One severe and one moderate side effect were observed with anti-TNFα respectively stage III anaphylactic shock and pain during injection associated with a redness of the site of injection and limping after the injection.¦Discussion¦Immunomodulating agents allow a rapid decrease in corticosteroid therapy, but one severe side effect was observed with anti-TNFa agents. These agents are considered in most countries as third line therapeutic agents.

Emergency Department Use by oldest-old Patients Between 2005 And 2010 in a Swiss University Hospital

Introduction: Population ageing challenges Emergency Departments (ED) with a population shift toward higher age groups. Patients aged 85+, represent the fastest growing segment, leading to more prevalent complex situations within ED. Method: Retrospective analysis of 56'162 ED visits of patients at the University of Lausanne Medical Center (CHUV), from 2005 to 2010. Results: ED visits of 65+ patients increased from 8'228 to 10'390/year, representing 6 patients/day more (+26%). 85+ Patients increased by +46% vs +20% for the 65-84 (+20% ED visits of people 18-64y). Median age of the 65+ ED patients increased from 78.7 to 79.3 years. 85+ patients were more likely than 65-84y patients to come from a NH setting (13% vs 4%) and to be hospitalised (70% vs 59%). Median length of stay difference between both age groups extended from 2 hours 08 min in 2005 to 2 hours 45 min in 2010. First reason to visit ED was fall/injury for 85+ patients (27%; 65-84: 18%) and a cardiovascular disorder for patients aged 65-84y (18%; 85+: 16%). Part of high degree of emergency cases (42%) and readmission to ED within 30 days (8%) were similar for both age classes (similar proportions in 2005 and 2010 for these 3 issues). Conclusion: Patients aged 85+ are the fastest growing group admitted to ED. Compared to younger counterparts, they use more ED ressources and the differences are increaseing overtime. ED addressing specific needs of geriatric patients would improve their care and lead to a better use of available resources.

Assessing the Functionality and Biocompatibility of a Wireless Contact Lens Sensor for 24 hour-intraocular Pressure Monitoring in Volunteers: Preliminary Results

Purpose: In vitro studies in porcine eyes have demonstrated a good correlation between induced intraocular pressure variations and corneal curvature changes, using a contact lens with an embedded microfabricated strain gauge. Continuous 24 hour-intraocular pressure (IOP) monitoring to detect large diurnal fluctuation is currently an unmet clinical need. The aims of this study is to evaluate precision of signal transmission and biocompatibility of 24 hour contact lens sensor wear (SENSIMED Triggerfish®) in humans. Methods: After full eye examination in 10 healthy volunteers, a 8.7 mm radius contact lens sensor and an orbital bandage containing a loop antenna were applied and connected to a portable recorder. Best corrected visual acuity and position, lubrication status and mobility of the sensor were assessed after 5 and 30 minutes, 4, 7 and 24 hours. Subjective comfort was scored and activities documented in a logbook. After sensor removal full eye examination was repeated, and the registration signal studied. Results: The comfort score was high and did not fluctuate significantly, except at the 7 hour-visit. The mobility of the contact lens was minimal but its lubrication remained good. Best corrected visual acuity was significantly reduced during the sensor wear and immediately after its removal. Three patients developed mild corneal staining. In all but one participant we obtained a registration IOP curve with visible ocular pulse amplitude. Conclusions: This 24 hour-trial confirmed the functionality and biocompatibility of SENSIMED Triggerfish® wireless contact lens sensor for IOP-fluctuation monitoring in volunteers. Further studies with a range of different contact lens sensor radii are indicated.

Intravitreal ranibizumab in the treatment of choroidal neovascularization associated with idiopathic central serous chorioretinopathy.

PURPOSE: We evaluate the functional and anatomic outcome after intravitreal ranibizumab treatment in patients with choroidal neovascularization (CNV) related to chronic central serous chorioretinopathy (CSC). METHODS: This is a small case series of 5 eyes with CNV associated with chronic CSC treated with intravitreal injection of 0.5 mg ranibizumab in the Jules Gonin University Eye Hospital from July 2007 to July 2009. Baseline and monthly follow-up visits included best-corrected visual acuity (BCVA), fundus examination, and optical coherence tomography (OCT). Fluorescein and indocyanine green angiography (ICG) were performed at baseline and repeated at least every 6 months. RESULTS: We studied 5 eyes of 4 patients with a mean age of 66 years. Mean follow-up was 21 months (SD 1.9). The mean number of intravitreal injections administered for each patient was 10 (SD 4.6). The mean initial BCVA was 0.23 (decimal equivalent) (logMAR 0.64, SD 0.13). At the last follow-up, mean BCVA was 0.44 decimal equivalent (logMAR 0.36, SD 0.31). Mean central macular thickness (CMT) measured with OCT was 330 microm (SD 43) at baseline and decreased at the final follow-up to 243 microm (SD 44 ). Persistent intraretinal or subretinal fluid on OCT and/or multifocal areas of increased choroidal permeability on ICG angiographies were present in all patients at the last follow-up visit. CONCLUSIONS: Intravitreal ranibizumab appeared to be an effective treatment of CNV related to chronic CSC. However, residual intraretinal or subretinal fluid and increased choroidal permeability persisted. Prospective controlled studies are warranted to evaluate the long-term safety and efficacy of intravitreal ranibizumab.
