Abstract
BACKGROUND The Brazilian Cohort of Asthma São Paulo (BRASASP) had a well-characterized severe asthmatic in Brazil, with 12 years of follow-up under standard treatment. METHODS Sequential assessment of patients with uncontrolled asthma from BRASASP cohort was carried out with 12 years of follow-up, performing exams and comparing with previous measurements. RESULTS 50 from the 60 initial patients were reevaluated. Twelve years later, FEV1 and the FEV1/FVC ratio have significantly decreased, with a rate of loss of lung function of 11.8 and 14%, respectively, and worsening in small airway parameters such as RV/TLC. BMI, The Asthma Control Test (ACT) and Asthma Control Questionnaire (ACQ) scores haven't changed. However, exacerbations decreased by 56%. Mean daily inhaled corticosteroid use was similar over time, but daily oral corticosteroid use decreased, in addition to a significant reduction in induced sputum eosinophilic and neutrophilic profile and serum IgE. Rhinitis, sinusitis, and GERD were the main comorbidities. In quality of life according to respiratory questionnaire SGRQ, total score showed a huge improvement (62% of patients). CONCLUSIONS There was significant decrease in FEV1 and FEV1/FVC. Data of pulmonary functional small airway characteristics show globally affected airways. Although higher doses of medications, patients were still uncontrolled, but with reduction of exacerbations, daily use of oral corticosteroid, less eosinophils and neutrophils in induced sputum and lower levels of IgE. Improvement in quality of life in 62% of patients.

Abstract
Increased pancreatic cancer (PC) risk in first-degree relatives (FDRs) of PC patients with germline pathogenic/likely pathogenic variants (PLPV) is a motivator for cascade genetic testing. To date, unbiased FDR risk estimates for gene-specific risks of genetic cancer syndrome-associated cancers are unknown. These estimates would enhance genetic counseling of at-risk FDRs in families where the PC proband has been found to carry a PLPV. Study Aim: To objectively quantify gene-specific risks of six relevant cancers among FDRs of PC patients with germline PLPV in ATM, BRCA1, BRCA2, CDKN2A, MLH1, MSH2, MSH6, PALB2, and PMS2. Methods: In the prospective, clinic-based Mayo Clinic Biospecimen Resource for Pancreas Research registry, 4,562 PC patients had previously undergone germline genetic testing for pancreatic cancer-associated genes through either research studies or clinical testing. Of these, 234 PC probands were found to carry PLPV among 9 genes of interest and had provided detailed demographic and cancer data on their FDRs by questionnaire. We focused on six cancer types (ovary, breast, uterus, pancreas, colon, and malignant melanoma) in FDRs as reported by the probands. Standardized incidence ratios estimated risk by gene of six cancers among FDRs of PC patients carrying PLPV. Results: 1,670 FDRs (mean age 58.1+17.8SD; 48.9% female) were included in the study. We found significantly increased risk of ovarian cancer in female FDRs of PC probands who carry PLPV in BRCA1 (SIR 9.49, 95%CI:3.06-22.14) or BRCA2 (3.72, 95%CI:1.36-8.11), and breast cancer risks were higher with BRCA2 (2.62, 95%CI:1.89-3.54). Uterine cancer risk was increased in FDRs of PC probands who carry PLPV for Lynch Syndrome mismatch repair (MMR) (6.53, 95%CI:2.81-12.86). PC risk was also increased (ATM 4.53, 95% CI:2.69-7.16; BRCA2 3.45, 95%CI:1.72-6.17; CDKN2A 7.38, 95%CI:3.18-14.54; PALB2 5.39, 95%CI:1.45-13.79). Increased colon cancer risk was observed in FDRs of probands who carried MMR PLPV (5.83, 95%CI:3.70-8.75), while melanoma risk was elevated for FDRs of probands with CDKN2A PLPV (7.47, 95%CI:3.97-12.77). Conclusion: PLPV in nine syndrome-associated genes in PC probands are associated with increased risk of six cancers in FDRs in PC families. The findings underscore the importance of risk estimation of various other cancers in PC families for screening, early detection, and intervention. The gene-specific quantified cancer risks for FDRs of PC patients with syndrome-associated germline PLPV can inform counseling regarding extra-PC risks when considering cascade genetic testing.

Abstract
Abstract
Introduction: Identifying families with an underlying inherited cancer predisposition is a major goal of cancer prevention efforts. Mendelian risk models have been developed to better predict the risk associated with a pathogenic variant of developing breast/ovarian cancer (with BRCAPRO), and the risk of developing pancreatic cancer (PANCPRO). Given that pathogenic variants involving BRCA2 and BRCA1 predispose to all three of these cancers, we developed a joint risk model to capture shared susceptibility.
Methods: We expanded the existing framework for PANCPRO and BRCAPRO to model underlying risk of pancreatic, breast, and ovarian cancer. We then validated this model on three datasets each reflecting the target populations for these models, including patients referred to a high-risk genetics clinic, patients with multiple family members with pancreatic cancer who underwent genetic testing for BRCA1/2, as well as a prospective registry of pancreatic cancer families. The new model is designated BRCAPANCPRO.
Results: BRCAPANCPRO yielded good discrimination for differentiating BRCA1 and BRCA2 carriers from non-carriers (AUC = 0.84, 95% CI: 0.78, 0.87) and was reasonably well-calibrated for predicting future risk of pancreatic cancer (observed-to-expected (O/E) ratio = 0.82 [0.69, 0.94]). In these families, BRCAPANCPRO outperformed both the prior BRCAPRO and PANCPRO models.
Discussion: The BRCAPANCPRO model improves the identification of families with a pathogenic variant in BRCA2 or BRCA1, particularly for families where there is the co-occurrence of pancreatic cancer in addition to breast and/or ovarian cancer. The model also improves the prediction of pancreatic cancer among families with a pancreatic cancer family history, with or without breast and/or ovarian cancer.

Abstract
Only a small portion of patients with primary headaches are refractory to treatment concerning relief of headache episodes and prophylactic therapy of headaches. New methods of central and peripheral neurostimulation have been developed for these patients during the last few years and experience was mostly gained in small case series. The following overview gives a description of new stimulation methods, such as deep brain stimulation, occipital nerve stimulation, vagal nerve stimulation, neurostimulation of the sphenopalatine ganglion and transcranial magnetic stimulation.

Abstract
BACKGROUND Studies in the last decade showed high rates of poorly treated and poorly controlled asthma in the community. Extending these findings we describe the more recent situation in specialist respiratory care as the most frequent source of treatment provision using comprehensive clinical and patient assessments and exploring predictors for poor control. METHODS This is a German cross-sectional, clinical epidemiological study in a nationally representative stratified treatment prevalence sample of N = 572 outpatients diagnosed with allergic asthma (AA; females 58.2%, aged 47.5 ± 16.3 (16-81 years). Treating physicians completed standardized clinical assessments (lung function, laboratory, clinical findings, severity, illness and treatment history, asthma control [GINA]), supplemented by patients' self-report measures (EQ5-D, AQLQ, ACT) and mental health module (CIDI-SF). RESULTS A total of 65.4% of patients were rated (GINA) as controlled, 30.3% partially controlled, and 4.4% uncontrolled; the patient-rated ACT showed lower rates of control (19.9% controlled, 44.2% partial, 35.8% uncontrolled, kappa: 0.2). Consistent with findings of clinical measures, controlled asthma was highest among patients with pre-treatment stage I severity (83.6%) and decreased by pre-treatment severity (stage IV patients: 29.3%). Poorer control was associated with pre-treatment severity, nocturnal attacks, diminished adherence and comorbid anxiety/depression. Patients received complex multiple drug and non-drug interventions, largely consistent with guidelines. Degree of asthma control was associated with improved and even normalized quality of life findings. CONCLUSION In this representative sample of longterm treated AA patients in specialist respiratory care we find better control rates and better adherence to guidelines as previous studies. Despite remarkable differences in clinician- vs patient-rated control ratings even the initially most severe stage IV patients (12.9% of patients) showed remarkable control rates and close to normal quality of life. Intensified treatment (e.g. omalizumab) was associated with improved control. Poorer control was associated with higher initial severity, diminished adherence, comorbid anxiety/depression and old age. LIMITATION Findings apply to AA patients in respiratory specialist care sector which is likely to treat the more severely affected patients. Thus, findings cannot be generalized to the general population, other treatment settings or asthma types.

Abstract
In this cross-sectional study we used magnetic resonance imaging (MRI)-based voxel based morphometry (VBM) in a sample of HIV positive patients to detect structural gray and white matter changes. Forty-eight HIV positive subjects with (n = 28) or without (n = 20) cognitive deficits (mean age 48.5 ± 9.6 years) and 48 age- and sex-matched HIV negative controls underwent MRI for VBM analyses. Clinical testing in HIV patients included the HIV dementia scale (HDS), Unified Parkinson's Disease Rating Scale (UPDRS) and the grooved pegboard test. Comparing controls with HIV positive patients with cognitive dysfunction (n = 28) VBM showed gray matter decrease in the anterior cingulate and temporal cortices along with white matter reduction in the midbrain region. These changes were more prominent with increasing cognitive decline, when assigning HIV patients to three cognitive groups (not impaired, mildly impaired, overtly impaired) based on performance in the HIV dementia scale. Regression analysis including all HIV positive patients with available data revealed that prefrontal gray matter atrophy in HIV was associated with longer disease duration (n = 48), while motor dysfunction (n = 48) was associated with basal ganglia gray matter atrophy. Lower CD4 cell count (n = 47) correlated with decrease of occipital gray matter. Our results provide evidence for atrophy of nigro-striatal and fronto-striatal circuits in HIV. This pattern of atrophy is consistent with motor dysfunction and dysexecutive syndrome found in HIV patients with HIV-associated neurocognitive disorder.

Abstract
The 2008-2013 World Health Organization (WHO) action plan on noncommunicable diseases (NCDs) includes chronic respiratory diseases as one of its four priorities. Major chronic respiratory diseases (CRDs) include asthma and rhinitis, chronic obstructive pulmonary disease, occupational lung diseases, sleep-disordered breathing, pulmonary hypertension, bronchiectiasis and pulmonary interstitial diseases. A billion people suffer from chronic respiratory diseases, the majority being in developing countries. CRDs have major adverse effects on the life and disability of patients. Effective intervention plans can prevent and control CRDs, thus reducing morbidity and mortality. A prioritised research agenda should encapsulate all of these considerations in the frame of the global fight against NCDs. This requires both CRD-targeted interventions and transverse NCD programmes which include CRDs, with emphasis on health promotion and disease prevention.

Abstract
Although it is widely agreed that the cerebellum is necessary for learning and consolidation of new motor tasks, it is not known whether adaptation to kinematic and dynamic errors is processed by the same cerebellar areas or whether different parts play a decisive role. We investigated arm movements in a visuomotor (VM) rotation and a force field (FF) perturbation task in 14 participants with cerebellar degeneration and 14 age- and gender-matched controls. Magnetic resonance images were used to calculate the volume of cerebellar areas (medial, intermediate, and lateral zones of the anterior and posterior lobes) and to identify cerebellar structure important for the two tasks. Corroborating previous studies, cerebellar participants showed deficits in adaptation to both tasks compared with controls ( P < 0.001). However, it was not possible to draw conclusions from the performance in one task on the performance in the other task because an individual participant could show severe impairment in one task and perform relatively well in the other (ρ = 0.1; P = 0.73). We found that atrophy of distinct cerebellar areas correlated with impairment in different tasks. Whereas atrophy of the intermediate and lateral zone of the anterior lobe correlated with impairment in the FF task (ρ = 0.72, 0.70; P = 0.003, 0.005, respectively), atrophy of the intermediate zone of the posterior lobe correlated with adaptation deficits in the VM task (ρ = 0.64; P = 0.015). Our results suggest that adaptation to the different tasks is processed independently and relies on different cerebellar structures.

Abstract
The smaller of two equally weighted objects is judged to be heavier when lifted (size-weight illusion [SWI]). In contrast, fingertip forces show an initial size effect but adapt to the true object weights within a few trials. The aim of this study was to investigate possible contributions of the cerebellum to SWI, force anticipation, and adaptation based on object size and weight. Eighteen participants with isolated cerebellar degeneration and 18 age- and gender-matched controls alternately lifted objects of equal weight but different size in 40 trials. All participants perceived the small object to be heavier after lifting (perceptive SWI). Fingertip forces were significantly higher during the first lift of the large object compared with the small object in the control and cerebellar groups. For the load-force rate and lifting acceleration, effects of anticipation were significantly less in the cerebellar compared with the control group. Grip and load forces were adapted to object weight during repeated lifts in both groups. Preserved perceptive SWI in cerebellar patients supports the hypothesis that perceptive SWI depends on the function of the ventral visual path that receives no or few efferents from the cerebellum. The findings of preserved anticipation and adaptation of grip forces in cerebellar patients, however, were unexpected. Reduced anticipation of load forces suggests that the neural presentation of predictive grip- and load-force control may be different. Findings show that representation and adaptation of internal models of object characteristics are not exclusively located in the cerebellum.

Purpose
Pancreatic cancer (PC) is the fourth leading cause of cancer death in the United States for which no recommended screening guidelines are available. An estimated 34,290 deaths related to PC is expected to occur in 2008 and the 5-year relative survival rate for this cancer is 5% for all stages combined. A person's chance of developing this cancer increases three-fold if a first-degree relative has pancreatic cancer. The purpose of this study was to assess attitudes of unaffected family members in the Mayo Clinic Pancreas Cancer Family study toward PC cancer risk and future screening options. This is the first study to report such attitudes of PC family members.
Subjects and Methods
At-risk family members with two or more relatives affected with pancreas cancer in the kindred and primary care controls completed a survey asking about: perceived PC risk, degree of PC worry/concern, attitude toward cancer screening in general, and intentions regarding PC screening if it were a blood test or endoscopic ultrasound.
Results
386 family members in 109 PC kindreds and 1058 controls completed surveys. Forty-six percent of PC family members reported that it was likely they would develop PC during their lifetime compared to 6% of controls. Forty-one percent of family members reported having thoughts regarding the possibility of getting pancreatic cancer during the past month versus 4.6% of controls. Similarly, 74% of family members reported concern about getting PC as compared to 40.6% of controls. 94% of family members reported they would be likely to undergo a blood-based PC screening test compared to 89.7% of controls. For endoscopic ultrasound, 71% of family members would be likely to undergo screening as compared to 55% of controls. All comparisons were statistically significant.
Conclusion
Compared to controls, PC family members perceive their personal PC risk to be high and report a higher rate of PC-related cancer worry/concern. A high percentage of family members and controls indicate receptivity to PC screening, especially if it were a blood test. If the screening is more invasive (i.e. EUS), interest declines, particularly among controls. This information can help investigators to understand and address potential motivators and barriers to recruitment for future PC studies and indicates that there is a need to develop educational interventions among these families to reduce their actual and perceived pancreatic cancer risk.

Abstract
4584 Background: PETs (islet cell tumors) are uncommon and often indolent tumors, but little is known about the incidence of PETs in the US and trends in survival. Methods: The SEER registry was used to identify cases of functional PETs (fPETs) and non-functional PETs (nfPETs) diagnosed from 1973–2000. Benign insulinomas were excluded. Incidence rates were age adjusted to the standard US population for 2000. Results: Of 971 patients with PETs, 824 (85%) were nfPETs, 37 (4%) were malignant insulinomas, 88 (9%) were fPETs other than insulinoma, and data were missing for 22 (2%). The crude annual incidence of PETs (per 100,000) for all ages was 0.1 in females and 0.2 in males. The incidence was highest in the age group >70 years (0.4, Table ). Tumors were localized in 109 (11%), regionally advanced in 228 (23%), and distant metastases were present in 545 (56%). Patients with fPETs were younger than patients with nfPETs (mean age 54.2 vs. 57.6, p=0.038) and had a longer median survival (MS) (47 vs. 30 months (mos), p=0.001) but were as likely to have advanced disease (p=0.50). The 5 and 10 year overall survival was 45.3% vs. 32.7% and 31.7% vs. 18.1% for fPETs vs. nfPETs, respectively. MS was 95 mos for localized PETs, 66 mos in regionally advanced PETs and 19 mos for distant metastases (p<0.001). Race did not influence incidence and survival. On multivariate analysis, only age (p<0.0001) and stage (<0.0001) were independently associated with prognosis but the functional status of the tumor approached significance (p=0.053). Survival has improved over time with longer MS in patients diagnosed in later quartiles of the observation period (p<0.001, Table). This difference is not explained by stage migration, as patients in all four quartiles had a similar stage distribution (p=0.79). Conclusions: PETs are uncommon tumors and the prognosis is highly dependent on the stage and the age of the patients. Patients with fPETs may have a better prognosis than nfPETs. Survival has improved over time. [Table: see text] No significant financial relationships to disclose.

Abstract
BACKGROUND Omalizumab is a monoclonal antibody indicated for treatment of severe persistent allergic asthma inadequately controlled despite optimal controller therapy. We investigated whether patient selection could be targeted further. METHODS Data from seven randomized controlled omalizumab trials were analyzed to investigate whether pre-treatment patient baseline clinical characteristics could be identified that were predictive of a superior response to omalizumab. We also studied whether patients who respond to omalizumab following a course of treatment could be reliably identified. Univariate/multivariate analyses of INNOVATE data were performed to identify predictive baseline measures and further investigated in efficacy analyses of pooled data from seven studies. The best method of identifying responders to omalizumab following treatment was determined by assessing the ability of various clinical response criteria to identify responders and discriminate patient exacerbation and other outcomes. RESULTS Baseline total immunoglobulin E (IgE) was the only predictor of efficacy in INNOVATE. However, pooled analysis showed treatment benefits irrespective of IgE levels. In omalizumab-treated patients, physician's overall assessment following a course of treatment identified 61% as responders and best discriminated treatment outcomes. CONCLUSION Baseline characteristics do not reliably predict benefit with omalizumab. Physician's overall assessment after 16 weeks of treatment is the most meaningful measure of response to therapy.

Abstract
Carotid artery disease is a frequent risk factor for ischemic stroke. Carotid endarterectomy was considered to be the standard treatment for high graded stenosis until carotid artery stenting (CAS) developed with promising results in early series and randomized trials. At present, stenting is supported in patients at high risk for surgery. Randomized trials analyzing low risk patient groups and studying the long-term results of CAS are necessary and partly underway. Although randomized trials are not yet available, current evidence suggests that cerebral protection devices reduce the number of neurological events. This review discusses the results of randomized trials and clinical series.
