Abstract
Genetic counselors (GCs) provide risk assessment, education, and counseling about the genetic contribution to disease. To do so, they must effectively communicate, build rapport, and help patients make the best decisions for themselves and their families. Language barriers add a complex layer to this patient-provider dynamic. While interpreters serve as a primary solution when a patient and GC speak different languages, issues have been documented with these sessions, such as misinterpreted genetic terminology (Gutierrez et al., 2017). Having a GC with concordant language skills may help address these barriers. The purpose of this study was to assess Spanish-speaking patients' perspectives on communication, decision-making, and the interpersonal relationship developed with a bilingual GC in language concordant cancer genetic counseling sessions. Spanish-speaking patients, ages 18 or older, seen by a Spanish-speaking GC at a California public, safety-net hospital were eligible to participate in this study. Nine participants were interviewed via telephone by the bilingual researcher using a semi-structured interview guide to assess three domains: communication, decision-making, and interpersonal relationship. Analyses of interview transcripts identified themes within these three areas of focus: (1) participants felt all explanations were clear and they were not afraid to ask questions in the session, (2) participants experienced preference-concordant decision making, and (3) participants felt empowered and supported by the GC. Participants suggested that GCs working with Spanish-speaking patients in the future should consider group counseling sessions, engaging in outreach efforts to educate the Spanish-speaking community about genetics, and increasing the number of GCs who speak Spanish. These results demonstrate the positive experiences of Spanish-speaking patients in language concordant cancer genetic counseling sessions and further support the need for recruitment of Spanish-speaking individuals into the profession. Future research should further assess the experience of Spanish-speaking patients in language concordant sessions and address the role of cultural concordance in sessions.

Backgroung
Leadless pacemakers (LPM) were developed to overcome complications related to endovenous devices. Devices carrying an accelerometer-based atrial sensing algorithm provided good AV synchrony in a 5-hours study.
Methods
Prospective study of patients implanted with LPM capable of AV synchronous pacing at our institution. We performed a close follow-up consisting of device check-ups 24 h after the implant and 1-3-6-12 months later. Changes in programming were guided by device counters and rate histograms. Once AV synchrony derived from counters (AM-VP + AM-VS) remained stable for at least two consecutive months, a 24 hours Holter monitoring was performed. ECG recordings were automatically and blindly analyzed with a delineation system based on the wavelet transform developed by Martinez et al.1 Cardiac cycles were defined as synchronous if a ventricular event followed the P-wave by ≤300 ms. AV synchrony was calculated by dividing the number of synchronous cycles by the total number of cardiac cycles.
Our aim was to describe AV synchrony in a real-world setting and to determine which echocardiographic and programming parameters were related to optimal AV synchrony (≥85% of total cardiac cycles).
Results
A total of 18 patients (12 males, mean age 82.6 ±8.1) were included. Indications for pacing were complete AV block (n=10) and second-degree AV block (n=8). Device reprogramming was needed in all patients at follow-up. The 24 h Holter monitoring was performed 118.8±43.8 days after the implant. Implant data and, device settings and programming at Holter date is displayed in Table 1. One patient was excluded from the analysis due to the development of severe sinus node disease. Total ECG recorded time was 386.8 hours and 1,537,995 cardiac cycles were analyzed.
Median AV synchrony, after Holter monitoring analysis, was 88.2% (interquartile range 79.9-95,1%) and 12 out of 17 patients showed an AV synchrony ≥85% of cardiac cycles. Optimal AV synchrony was related to smaller right atrium size (13.2±3.4 cm2 vs 15.6±1.2 cm2 for AV synchrony ≥85 and <85%, respectively) but no association appeared between diastolic parameters (E, A, E/A ratio, E´, A´) and AV synchrony. Rate smoothing algorithm was associated with higher rates of optimal AV synchrony (81.8% of patients with algorithm OFF vs 50% of patients activated). Besides, higher A3 threshold (7.1±3.5 m/s2 vs 4.2 ± 1.1 m/s2) and longer A3 window (620.8±25.7 ms vs 600 ms for AV synchrony ≥85% and <85%, respectively) were also linked to optimal AV synchrony. Multivariate analysis did not show any independent predictor of AV synchrony.
Conclusions
In our cohort of LPM patients we obtained high percentages of AV synchronous pacing in a real-life setting. Device reprogramming was often needed, and larger studies are desirable to confirm our data.

Abstract
Introduction With the global spread of COVID-19, studies in the US and UK have shown that certain communities have been strongly impacted by COVID-19 in terms of incidence and mortality. The objective of the study was to determine social determinants of health among COVID-19 patients hospitalized in the two major cities of Spain. Material and methods A multicenter retrospective case series study was performed collecting administrative databases of all COVID-19 patients ≥18 years belonging to two centers in Madrid and two in Barcelona (Spain) collecting data from 1st March to 15th April 2020. Variables obtained age, gender, birthplace and residence ZIP code. From ZIP code we obtained per capita income of the area. Predictors of the outcomes were explored through generalized linear mixed-effects models, using center as random effect. Results There were 5,235 patients included in the analysis. After multivariable analysis adjusted by age, sex, per capita income, population density, hospital experience, center and hospital saturation, patients born in Latin American countries were found to have an increase in ICU admission rates (OR 1.56 [1.13-2.15], p<0.01) but no differences were found in the same model regarding mortality (OR 1.35 [0.95-1.92], p=0.09). Conclusions COVID-19 severity varies widely, not only depending on biological but also socio-economic factors. With the emerging evidence that this subset of population is at higher risk of poorer outcomes, targeted public health strategies and studies are needed.

Abstract
Abstract
Background
The novel MICRA AV leadless pacemaker can provide atrioventricular (AV) synchronous pacing using an accelerometer-based atrial sensing algorithm.
Purpose
To describe the performance of MICRA AV pacemaker in a real-life setting and to determine the agreement between AV synchrony determined by the device counters and AV synchrony obtained by a 24 h ECG Holter test.
Methods
This pilot study included the first ten patients implanted with a MICRA AV leadless pacemaker at our institution. All implants were performed according to standard protocols and under deep sedation. A close follow-up was performed, and atrial sensing parameters were adjusted following AV synchrony given by the device counters. Patients underwent a 24 h ECG Holter test once AV synchrony remained stable for at least two months. The ECG Holter signal was analyzed in a blinded manner by an automatic delineation system based on the wavelet transform (Figure). This algorithm has a sensivity of 98.9% and a positive predictive value of 91.9% to detect p waves. Cardiac cycles were defined as synchronous if a QRS complex followed the P-wave by ≤300 ms, according to MARVEL 2 study criterion. AV synchrony obtained from the 24 h Holter test was compared with AV synchrony extracted from the device counters (AM-VP + AM-VS) during the same 24 h.
Results
From June to November 2020, 10 patients (7 males, mean age 83.5±5.4) were implanted with a MICRA AV leadless pacemaker (5 patients due to complete AV block and 5 patients due to second degree AV block). All devices were implanted after 1 deployment and no major complications appeared. Data related to implant parameters are displayed in Table 1. Device reprogramming was needed in all patients during follow-up. The 24 h ECG Holter monitoring was performed 141.4±45 days after the implant (mean time). Device settings and programming at Holter date is displayed in Table 1. Total ECG recorded time was 210.6 h and 915,488 cardiac cycles were analyzed. The mean percentage of synchronous cardiac cycles was 88.6±8.5% of total cycles while the mean AV synchrony determined by the device counters (AM-VP + AM-VS) during those 24 h was 89.8±5.5%. A good patient to patient correlation between these two measures was found (coefficient of intraclass correlation = 0.72).
Conclusions
We obtained high rates of AV synchrony with MICRA AV leadless pacemaker, in our short-term follow-up pilot study. Manual adjustment of the atrial sensing parameters, guided by the device counters, seems to be useful to obtain an optimal performance.

Abstract
Abstract
Background
Chronic Heart Failure (CHF) and its risk factors at stage A of the disease are conditions that trends to facilitate potassium (K+) derangements, for pathophysiology mechanisms and medication use than could facilitate both hyper- and hypokalamia. Studies on the associations between potassium derangements and clinical outcomes in these patient populations have yielded mixed findings, and the implications for healthcare expenditure are unknown.
Purpose
The objectives of our analysis was to asses the population-based associations between hyperkalemia, hypokalemia (compared to normokalemia) and all-cause death, urgent hospitalization, emergency department visits, daycare visits, and a yearly healthcare expenditure >85th percentile, in patients with chronic heart failure, chronic kidney disease, diabetes mellitus, hypertension and ischemic heart disease.
Methods
Population-based, longitudinal study including up to 36,269 patients from the Public Healthcare Area with at least one of those conditions. We used three linked administrative, hospital and primary care healthcare databases with exhaustive information on sociodemographics, medical diagnoses, pharmacy dispensing and laboratory data. Participants were identified and followed between 2015 and 2017, had to be ≥55 years old and have at least one serum potassium measurement recorded; and were classified as hyperkalemic, hypokalemic or normokalemic. Four analytic designs were used to evaluate prevalent and incident disease cases as well as prevalent and incident use of renin-angiotensin-aldosterone system inhibitors
Results
The majority of study participants remained normokalemic during the 3 months following study entry (ranging 94%–96%) and hyperkalemia was twice as frequent as hypokalemia. In all analyses, compared to normokalemic patients those with hyperkalemia had a worse crude event-free survival for all endpoints, and the worst survival was observed for hypokalemic patients [see Figure 1: prevalent case analysis; Kaplan-Meier cumulative survivor function curves for all-cause death (upper left), hospitalization (upper right), ED visits (lower left) and daycare visits (lower right)].
In multivariable-adjusted analyses, hyperkalemia was robustly and significantly associated with an increased risk of all-cause death (hazard ratios from Cox regression models ranging 1.31–1.68) and with an increased odds of a yearly healthcare expenditure >85th percentile (odds ratios 1.21–1.29). Associations were even stronger in hypokalemic patients (hazard ratios for all-cause death 1.92–2.60; odds ratios for healthcare expenditure >percentile 85th 1.81–1.85).
Conclusions
Experimental studies are needed to confirm whether prevention of potassium derangements reduces mortality and healthcare expenditure in patients with these chronic conditions. Until then, our findings provide further observational evidence on the potential importance of maintaining normal potassium levels in this setting.

Abstract
Abstract
Background
Reduction of readmissions in heart failure (HF) patients is a main goal of HF programmes. Establishing a discharge planning for the patient and coordinating it with primary care teams are key aspects for their success.
Purpose
Evaluate whether a double check discharge planning based on adding face-to-face joint weekly sessions with primary care managers to the conventional electronic communication of care plan reduces 6-month readmission and 6-month mortality.
Methods
We evaluated all patients discharged from hospital with HF as primary diagnosis between September 2017 and January 2019. We compared outcomes between patients discharged during Period #1 (single check; September 2017 - April 2018) and those discharged during Period #2 (double check; May 2018 - January 2019).
Primary endpoint was the combined endpoint of all-cause death or all-cause hospitalization 6 months after discharge from the index hospitalization.
Results
The study enrolled 317 patients: 182 in Period #1 and 135 in Period #2.
Mean age was 76±9 years. There was a higher proportion of patients with diabetes and COPD in Period #1, with no differences in other baseline characteristics.
The combined endpoint of all cause-death and all-cause hospitalization at 6 months was significantly reduced in patients in the double check discharge planning group (27% vs. 16%, p 0.021).
Conclusions
In a HF programme, the addition of a double check discharge planning based on having joint weekly sessions with primary care managers on top of the conventional electronic communication of care plan reduces 6-month readmission and 6-month mortality.

Abstract
Abstract
Background
Efficacy of HF programmes in oldest old (octogenarians and nonagenarians) has not been fully explored.
Methods
We conducted a natural experiment evaluating all patients after hospitalization for heart failure as primary diagnosis between January 2017 and January 2019. We compared outcomes between patients discharged during Period #1, before the implementation of the program with patients discharged during Period #2, after the implementation of the 7-step bundle of interventions. We explored the interaction between age group (<80 vs. ≥80 years old) by the intervention modality (HF programme vs. usual care). Primary end-point was the combined end-point of all-cause death or all-cause hospitalization at 6 months after discharge from the index hospitalization.

The study enroled 440 patients. Mean age of the whole cohort was 75±9 years. In the oldest old subgroup (n=160), mean age was 84±3. No differences were found in baseline characteristics of patients between usual care and HF program. 30-day all-cause readmission was significantly reduced in patients in the HF programme group compared to patients in the usual care group in both age strata. In unadjusted Cox regression analyses in the oldest old group, management of patients in the HF programme was significanty associated with a reduction in the risk of the primary end-point (HR: 0.50; 95% CI [0.29–0.85]; p=0.011).
Conclusions
Management of patients in a nurse-led integrated care-based heart failure programme results in reduction of all-cause death or all-cause hospitalizations in oldest old patients.

Abstract
Abstract
Introduction
In patients with chronic cardiovascular, metabolic and renal disorders, potassium (K)+ homeostasis is often delicate, especially in the presence of renin-angiotensin-aldosterone system inhibition (RAASI) and/or diuretic therapies. In this context, current clinical practical guidelines for the management of these patients recommend close monitoring of renal function and K+ levels, particularly in the presence of drug titration. Nevertheless, very limited epidemiological data on their importance at a population level is available.
Purpose
The objectives of the present analysis are to estimate the prevalence of potassium (K+) derangements in five key chronic cardiovascular, metabolic and renal conditions at the population level, its use of RAASI medication and describe potassium derangements among RAASI users.
Methods
We used data from more than 375,000 individuals 55 years of age or older included in the population-based healthcare database of a public Institute of Health between 2015 and 2017. The conditions of interest were chronic heart failure (CHF), chronic kidney disease (CKD), diabetes mellitus (DM), ischemic heart disease (IHD), and hypertension (HTN). RAASI medications included angiotensin converting enzyme inhibitors, angiotensin II receptor blockers, mineralocorticoid receptor antagonists (MRAs), and rennin inhibitors. Hyperkalemia was defined as K+ levels >5.0 mEq/L and hypokalemia as K+ <3.5 mEq /L
Results
The prevalence of chronic cardiovascular, metabolic and renal conditions was high, particularly of HTN (48.2–48.9%). The prevalence of hyperkalemia was ranging between 10% and 25% depending of the condition, more frequent in CKD and less frequent in HTN patients. In figure, we display the prevalence of hyperkalemia among individuals with each of the relevant chronic conditions, January 1st, 2016 and January 1st, 2017. Use of at least one RAASI medication was very prevalent in HTN patients (75.2–77.3%). Among RAASI users, the frequency of K+ derangements and mainly of hyperkalemia was very noticeable (12% overall), especially in patients with CKD, CHF, elderly individuals, and users of MRAs. Hypokalemia was less frequent (1%).
Conclusion
The high prevalence of K+ derangements and predominantly hyperkalemia among RAASI users highlights the real-world relevance of K+ derangements and the importance of close monitoring and management of K+ levels in routine clinical practice. This is likely to benefit a large number of patients, particularly those at higher risk.

Abstract
Abstract
Background
Self care is a crucial factor in the education of patients with heart failure (HF) and directly impacts in the progression of the disease.
Beyond heart failure related factors, the role of psychosocial determinants and its interaction with clinical aspects has not been fully explored.
Aims
The aim of the study was to analyze both clinical and psychosocial factors associated with poor self care in patients with chronic HF.
Methods
Self care was evaluated at baseline with the 9 item European HFR Self Care Behaviour Scale (9 item ESCBS).
Scores were standardized and reversed from 0 (worst self care) to 100 (better self care). This study we analysed the associations between poor self care (defined as scores in the lower tertile of the 9 item ESCBS) with demographic, HF-related (clinical) and psychosocial factors in all patients at baseline.
Results
We included 1123 patients: mean age 72±11, 639 (60%) were male, mean LVEF 45±17 and 454 (40%) were in NYHA class III or IV. Mean score of the 9-item ESCBS was 69±28. In the clinical multivariate analyses HF-related factors associated with poor self-care were serum albumins level, ckd level and previous admission due to heart failure. In the psychosocial multivariate analyses poor social support, depressive symptoms and needing a caregiver were independently associated with poor self care. In combined models, only psychosocial factors were independently associated with poor self care whereas no clinical factors remain in the model.
Conclusion
Our study showed that psychosocial conditions are the main factors independently associated with poor self-care in patients with chronic heart failure

Abstract
Abstract
Background
Self-care is a crucial factor in the education of patients with heart failure (HF) and directly impacts in the progression of the disease. However, little is published about its major clinical implications as admission or mortality in patients with HF.
Aims and methods
The aim of the study was to analyze time to admission due to acute heart failure and mortality associated with poor self-care in patients with chronic HF.
We prospectively recruited consecutive patients with stable chronic HF referred to a nurse-led HF programme. Selfcare was evaluated at baseline with the 9 item European Heart Failure Self-Care Behavior Scale. Scores were standardized and reversed from 0 (worst selfcare) to 100 (better self care). For the purpose of this study we analyzed the associations of worse self-care (defined as scores below the lower tertile of the scale) with demographic, disease-related (clinical) and psychosocial factors in all patients at baseline.
Results
We included 1123 patients, mean age 72±11, 639 (60%) were male, mean LVEF 45±17 and 454 (40,4%) were in NYHA class III or IV. Mean score of the 9-item ESCBE was 69±28. Score below 55 (lower tertile) defined impaired selfcare behaviour.
Those patients with worse self-care had more ischaemic heart disease, more COPD, and they achieved less distance in the 6 minute walking test. Regarding psychosocial items patients in lower tertile of self-care needed a caregiver more frequently, they present more cognitive impairment, depressive symptoms and worse score in terms of health self-perception.
Multivariate Cox Models showed that a score below 55 points in 9-item ESCBE was independently associated with higher readmission due to acute heart failure [HR 1.26 (1.02–1.57), p value=0.034] and with mortality [HR 1.24 CI95% (1.02–1.50), p value=0.028]
Conclusion
Poor self-care measured with the modified 9-item ESCBE was associated with higher risk of admission due to acute decompensation and higher risk of mortality in patients with chronic heart failure.
These results highlight the importance of assessing self-care and provide measures to improve them.

Abstract
Abstract
Background
Prevalence of congestive heart failure (CHF) and predisposing conditions has described previously. Most of these studies evaluated centre-European or north-American populations. However, the prevalence and evolutionary changes of Heart Failure stages A, B and C has not been fully elucidated in Mediterranean cohorts.
Purpose
To estimate the prevalence of CHF (HF Stage C) and four additional key chronic cardiovascular, metabolic and renal conditions predisposing to the development of CHF (HF Stages A and B) at a population level in a south-European healthcare area. We analysed the evolutionary changes in the prevalence in these five conditions.
Methods
In a healthcare area of 1,3Millions inhabitants, we extracted health related information of all individuals ≥55 years old. We analysed data of 375,233 individuals included in the population-based healthcare database of a public Institute of Health between 2015 and 2017. The conditions of interest were CHF, chronic kidney disease (CKD), diabetes mellitus (DM), ischemic heart disease (IHD) and hypertension (HTN).
Results
The prevalence of chronic conditions was high, particularly of HTN (48.2–48.9%) and DM individuals (14.6–14.8%). The other conditions were less frequent, with prevalence around 2–4% for IHD, 5–9% for CKD and 2–4% for CHF (Table). However, the less frequent conditions had a striking upward trend with over 1,500 new prevalent cases per year between 2015 and 2017 for CHF (45% relative increase), more than 2,500 new prevalent cases for IHD (67% relative increase) and more than 4,000 new prevalent cases per year for CKD (44% relative increase).
Conclusion
In this south European cohort, there were a high prevalence of HTN and DM as risk factors and a significant trend of increasing prevalence in high cost chronic conditions such as CHF, IHD and CKD.

Abstract
Abstract
Background
Reduction of 30-day readmission in heart failure (HF) patients is a main goal of health-care systems. Programmes to decrease 30-day readmission have successfully reduced it but have failed to neither maintain benefit afterwards nor decrease mortality. Moreover, in many cases the price of reducing 30-day readmission is a mortality increase.
Purpose
Evaluate whether the impact of a fully nurse-led HF programme directed to reduce 30-day readmission and mortality extends to longer periods of time, including 90 days and 180 days after discharge.
Methods
We evaluated all patients discharged from hospital with HF as primary diagnosis between January 2017 and January 2019. We compared outcomes between patients discharged during Period #1 (pre-programme; Jan 2017 - Aug 2017) and those discharged during Period #2 (HF programme; Sept 2017 - Jan 2019).
Primary endpoint was the combined endpoint of all-cause death or all-cause hospitalization 90 days and 180 days after discharge from the index hospitalization.
Results
The study enrolled 440 patients: 123 in Period #1 and 317 in Period #2.
Mean age was 75±9 years. There was a higher proportion of female patients in Period #2 (38.2% vs 26.8%, p=0.025), with no differences in other baseline characteristics.
The combined endpoint of all cause-death and all-cause hospitalization was significantly reduced in patients in the HF programme group, both at 90 days [OR 0.37 (0.22–0.63), p<0.001] and at 180 days [OR 0.27 (CI 0.17–0.43), p<0.001]. Such a decrease was at expense of a reduction in cardiovascular (CV) hospitalization and HF hospitalization.
There were no differences between groups in mortality [OR 0.96 (0.18–5.00), p=0.293].
Conclusions
A fully nurse-led HF programme reduces the combined endpoint of all-cause death and all-cause hospitalization both at 90 days and 180 days after an index discharge for HF.
Such a decrease is driven by a reduction of CV and HF hospitalization, which are maintained over time. There were no differences between groups in mortality.

Abstract
Background:The CAREGIVERS questionnaire is used as a multidimension screening instrument for burden of caregivers, it allows to examine the impact of juvenile idiopathic arthritis (JIA) on several areas of the caregiver’s life, looking for specific concerns and needs in which treatment could be required. This instrument has shown a good understanding among participants, reliability and consistency to measure the psychosocial and economic impact on primary caregivers of patients with JIA.Objectives:The aim of this study is to validate CAREGIVERS questionnaire with the most common pediatric rheumatic diseases, such as JIA, systemic lupus erythematosus (SLE) and juvenile dermatomyositis (JDM).Methods:The external validation phase of the constructed questionnaire will be carried out following Feinstein’s clinimetric and psychometrics methodology, to measure the impact of the disease on the caregiver and create a risk profile for treatment detachment.Results:A total of 200 questionnaires are applied to caregivers of pediatric patients with rheumatic diseases: 109 caregivers of patients with JIA, 28 caregivers of patients with DMJ and 63 caregivers of patients with SLE. When analyzing all the questions together, a general Cronbach’s alpha of 0.6751 was obtained (Table 1).Table 1.External validation of the QuestionnaireDimensionNumero de ÍtemsAlfa de CronbachI.

Abstract
Background Cytomegalovirus infection dramatically decreased with the introduction of antiretroviral therapy. Whether incidence, clinical characteristics and prognosis of cytomegalovirus in HIV infected patients, has changed over time is. scarcely known. Methods Retrospective single-center study. Patients included in this study were all HIV infected patients that went to our center for any disease, and were diagnosed with cytomegalovirus, during the period 2004–2015. epidemiological, clinical and laboratory patients variables were collected in a clinical database. Clinical characteristics, incidence of cytomegalovirus and predictors of mortality during the study were assessed. Results were considered statistically significant when p < 0.05. All statistical analyses were calculated by SPSS version 20.0 (Chicago, IL,USA). Results Fifty-six cases of cytomegalovirus infection, in HIV infected patients were identified during the study period (incidence rate-1.7 cases per 1000 persons/year). The most frequent presentation was systemic illness in 43% of cases. Of note,no patients presented with ophthalmic manifestations. The 30-days mortality was 18%. Predictors of mortality were, in the univariate analysis, admission to the intensive care unit OR 32.4 (3.65–287.06) p = 0.0001, and mechanic ventilation 84 OR (8.27–853.12) p = 0.0001, and ART OR 4.1 (0.97–17.31) p = 0.044. These variables were assessed by multivariate analysis, and only mechanical ventilation was statistically significant (p < 0.05) Conclusion Incidence of cytomegalovirus infection was higher than described in the antiretroviral therapy era. Clinical presentation has changed. Mechanic ventilation predicted mortality.

Abstract
Abstract
Introduction
The role of cardiopulmonary exercise testing (CPET) is unquestionable to assess prognosis in heart failure. In patients with valvular heart disease (VHD), the functional capacity (FC) is crucial to aid in the right timing of surgery. The aim of this study was to compare the assessment of the FC by CPET and NYHA and the correlation between ventilatory efficiency parameters and resting systolic pulmonary artery pressure (SPAP).
Methods
We studied 100 VHD patients (57% female) who underwent a CPET. We calculated the real METS (RM) as indexed peak VO2/3.5 (1 MET=3.5 ml O2/kg/min) and compared to estimated METS (EM) derived by the time of exercise. An agreement analysis between RM, EM and NYHA was calculated. The correlation among VE/Vslope CO2, EqCO2at anaerobic threshold (AT), PETCO2, partial pressure end-tidal CO2 at AT and SPAP was analyzed.
Results
The results are shown in Table and Figure. The RM and the EM were 4.7±1.7 and 5.5±3, respectively (p<0.01) with a low agreement (ICC=0.6, p<0.01). The agreement between NYHA and the classification obtained from peak % of predicted peak VO2 was very low (weighted kappa =0.06, p=0.28). In patients with severe mitral VHD, the ventilatory efficiency parameters were correlated with SPAP (PETCO2 (AT), r=−0.7, p=0.002; EqCO2 (AT), r=0.5, p=0.04:VE/Vslope CO2, r=0.3, p 0.2), whereas in those with severe aortic VHD, these correlations were much lower (PETCO2 (AT), r=−0.3, p=0.13; EqCO2 (AT), r=0.2, p=0.15; VE/Vslope CO2, r=0.18, p 0.31).
Total (n=100) Mitral regurgitation (n=35) Aortic regurgitation (n=23) Age 65 (29–86) 66 (30–84) 65 (11–87) LVEF (%) 62±6 63±6 61±7 SPAP (mmHg) 40±11 39±11 36±8 NYHA I (60%), II (33%), III (7%) I (63%), II (29%), III (9%) I (63%), II (33%), III (4%) Indexed peak VO2 (ml/min/kg) 16±6 17±6 19±8 Peak % predicted VO2 73±18 74±17 79±18 Predicted VO2 AT (%) 58±19 54±19 61±22 Eq CO2 AT 33±6 32±7 32±5 VE/VSlope CO2 33±6 32±7 33±8 PetCO2 AT 34±4 36±4 36±5
Type and degree of VHD
Conclusions
NYHA scale and estimation of METS derived from the time of exercise clearly overestimated the FC of our population. In our series, the ventilatory inefficiency in patients with mitral VHD could be a surrogate marker of advanced disease and could lead to an earlier intervention.

Abstract
PURPOSE Several genes on hereditary breast and ovarian cancer susceptibility test panels have not been systematically examined for strength of association with disease. We employed the Clinical Genome Resource (ClinGen) clinical validity framework to assess the strength of evidence between selected genes and breast or ovarian cancer. METHODS Thirty-one genes offered on cancer panel testing were selected for evaluation. The strength of gene-disease relationship was systematically evaluated and a clinical validity classification of either Definitive, Strong, Moderate, Limited, Refuted, Disputed, or No Reported Evidence was assigned. RESULTS Definitive clinical validity classifications were made for 10/31 and 10/32 gene-disease pairs for breast and ovarian cancer respectively. Two genes had a Moderate classification whereas, 6/31 and 6/32 genes had Limited classifications for breast and ovarian cancer respectively. Contradictory evidence resulted in Disputed or Refuted assertions for 9/31 genes for breast and 4/32 genes for ovarian cancer. No Reported Evidence of disease association was asserted for 5/31 genes for breast and 11/32 for ovarian cancer. CONCLUSION Evaluation of gene-disease association using the ClinGen clinical validity framework revealed a wide range of classifications. This information should aid laboratories in tailoring appropriate gene panels and assist health-care providers in interpreting results from panel testing.

Abstract
BACKGROUND The relationship between helminthiases and allergy is a matter of considerable interest and research. In the tropics, house dust mite exposure, a known risk factor for asthma, is frequently concurrent with helminth infections. It remains to be defined whether infection with the common roundworm Ascaris or its bystander immunological effects influence the prevalence and pathogenesis of asthma independently of mite sensitization. OBJECTIVE To investigate the relationship between the IgE responses to Ascaris and its purified allergens and the risk of asthma in a tropical country. METHODS A nested case-control study was performed in 356 subjects who reported current and past asthma symptoms (asthmatics) and 435 controls that had never experienced such symptoms. They were tested for serum levels of total IgE and specific IgE to Ascaris extract, Asc s 1 (ABA-1), Asc l 3 (tropomyosin) and GST (glutathione transferase). In addition, specific IgE to Dermatophagoides pteronyssinus, Blomia tropicalis and their tropomyosins Der p 10 and Blo t 10 was measured. Sensitization was defined as a positive specific IgE result to any extract or recombinant allergen. RESULTS Sensitization to Ascaris and D. pteronyssinus was independently associated with asthma after adjustment for age, gender, socio-economic stratum, city and other IgE levels (adjusted ORs: 2.17; 95% CI 1.37-3.42 and 2.46; 95% CI 1.54-3.92), respectively. There was also a significant association with sensitization to the highly allergenic and cross-reactive tropomyosins Asc l 3, Blo t 10 and Der p10 (aORs: 1.76; 95% CI 1.21-2.57, 1.64; 95% CI 1.14-2.35 and 1.51; 95% CI 1.02-2.24), respectively. CONCLUSION AND CLINICAL RELEVANCE IgE responses to Ascaris are associated with asthma symptoms in a population living in the tropics. Sensitization to the cross-reactive Ascaris and mite tropomyosins partially underlies this finding. These results have potential relevance in asthma diagnosis and management.

Abstract
The brains of patients with Alzheimer's disease (AD) present elevated levels of tumor necrosis factor-α (TNFα), a cytokine that has a dual function in neuronal cells. On one hand, TNFα can activate neuronal apoptosis, and on the other hand, it can protect these cells against amyloid-β (Aβ) toxicity. Given the dual behavior of this molecule, there is some controversy regarding its contribution to the pathogenesis of AD. Here we examined the relevance of the long form of Fas apoptotic inhibitory molecule (FAIM) protein, FAIM-L, in regulating the dual function of TNFα. We detected that FAIM-L was reduced in the hippocampi of patients with AD. We also observed that the entorhinal and hippocampal cortex of a mouse model of AD (PS1M146LxAPP751sl) showed a reduction in this protein before the onset of neurodegeneration. Notably, cultured neurons treated with the cortical soluble fractions of these animals showed a decrease in endogenous FAIM-L, an effect that is mimicked by the treatment with Aβ-derived diffusible ligands (ADDLs). The reduction in the expression of FAIM-L is associated with the progression of the neurodegeneration by changing the inflammatory response mediated by TNFα in neurons. In this sense, we also demonstrate that the protection afforded by TNFα against Aβ toxicity ceases when endogenous FAIM-L is reduced by short hairpin RNA (shRNA) or by treatment with ADDLs. All together, these results support the notion that levels of FAIM-L contribute to determine the protective or deleterious effect of TNFα in neuronal cells.

Abstract
BACKGROUND Hyperparathyroidism is a common complication of chronic renal failure. A functioning kidney graft improves hyperparathyroidism but it can persist to some degree for years. Persistent hyperparathyroidism associated with hypercalcemia and hyperphosphatemia have been associated with poor graft and patient survivals. The purpose of the present work was to assess the association between calcium/phosphate mineral metabolism markers and graft outcomes. PATIENTS AND METHODS Among 389 renal transplantations performed in our center between January 2000 and June 2008, 331 patients had functioning grafts at 12 months, the subjects of this study. Measurements of intact parathyroid hormone (iPTH), serum calcium and phosphate, tubular phosphate reabsorption, and urinary calcium excretion were performed at 1, 3, 6, and 12 months. The mean follow-up was 84.0 ± 31.8 months. RESULTS During the follow-up period, 63 grafts (19.0%) were lost, 30 patients (9.0%) died, and 80 recipients (24.2%) presented at least one cardiovascular event. Univariate Cox proportional analysis showed high iPTH levels at 1 and 12 months after transplantation to not be associated with worse patient or graft survival or an higher risk of cardiovascular events. Serum phosphate and calcium concentrations as well as calcium-phosphate products during the first year after transplantation were not associated with graft and patient outcomes or cardiovascular events. However, serum calcium at 12 months showed an inverse association with graft survival after adjusting for other variables (hazard ratio 0.61; 95% confidence interval 0.40-0.94; P = .026). CONCLUSIONS iPTH levels and serum phosphate concentrations and calcium-phosphate products during the first year after transplantation were not associated with graft outcomes. The inverse association between adjusted calcium and graft survival should be studied further.

Abstract
Whether insulin-like growth factor I (IGF-I) signaling in Alzheimer's disease (AD) is beneficial or detrimental remains controversial. We now show that a competitive regulation by IGF-I of the phosphatase calcineurin in reactive, but not in quiescent astrocytes drives Alzheimer's pathology. Calcineurin de-phosphorylates the transcription factor Foxo3 in response to tumor necrosis factor-α (TNFα), an inflammatory cytokine increased in AD, activating nuclear factor-κB (NFκB) inflammatory signaling in astrocytes. In turn, IGF-I inactivates and displaces Foxo3 from calcineurin in TNFα-stimulated astrocytes by recruiting the transcription factor peroxisome proliferator-activated receptor-γ, and NFκB signaling is inhibited. This antagonistic mechanism reversibly drives the course of the disease in AD mice, even at advanced stages. As hallmarks of this calcineurin/Foxo3/NFκB pathway are present in human AD brains, treatment with IGF-I may be beneficial by antagonizing it.

Abstract
Current evaluation functions for heuristic planning are expensive to compute. In numerous planning problems these functions provide good guidance to the solution, so they are worth the expense. However, when evaluation functions are misguiding or when planning problems are large enough, lots of node evaluations must be computed, which severely limits the scalability of heuristic planners. In this paper, we present a novel solution for reducing node evaluations in heuristic planning based on machine learning. Particularly, we define the task of learning search control for heuristic planning as a relational classification task, and we use an off-the-shelf relational classification tool to address this learning task. Our relational classification task captures the preferred action to select in the different planning contexts of a specific planning domain. These planning contexts are defined by the set of helpful actions of the current state, the goals remaining to be achieved, and the static predicates of the planning task. This paper shows two methods for guiding the search of a heuristic planner with the learned classifiers. The first one consists of using the resulting classifier as an action policy. The second one consists of applying the classifier to generate lookahead states within a Best First Search algorithm. Experiments over a variety of domains reveal that our heuristic planner using the learned classifiers solves larger problems than state-of-the-art planners.

Abstract
BACKGROUND The need for organs for renal transplantation has encouraged the use of grafts from increasingly older donors. Earlier studies performed in Spain have shown the suitability of donors aged 60-65 years. In this single-center study, we evaluated our results using donors >70 years old. METHODS We evaluated 401 primary transplantations performed from January 2000 to December 2009. Their initial immunosuppression was a tacrolimus-based (n = 324), cyclosporine-based (n = 70) or calcineurin inhibitor-free (n = 7) regimen patients. Recipients were classified according to the donors age: <50 (42.6%); 50-70 (39.7%) and >70 (17.5%) years. RESULTS There were no differences in recipient or donor gender, time on dialysis, cold ischemia, delayed graft function, or acute rejection episodes. However, the mean age was higher among patients who received grafts from donors >70 years old; 42.5 ± 12.4 years for <50, 58.1 ± 8.2 years for 50-70, and 65.7 ± 7.2 years for >70; (P = .000). The serum creatinine at 12 months was increased according to the age of the donor; 1.4 ± 0.6, 1.8 ± 0.6, 70 and 1.7 ± 0.5 mg/dL, respectively (P = .001). The graft survival rates at 5 years were 81%, 74%, and 70%, respectively (P = .519). Upon multivariate analysis only HLA-DR mismatches, delayed graft function, and acute rejection episodes were associated with graft loss. Patient survival rates (86%) at 5 years were similar among recipients from donors aged 50-70 and >70 years, but higher (96%) for those who received a graft from a donor <50 years (P = .003). CONCLUSIONS Nearly 20% of donors were >70 years old in our study. Their kidneys displayed excellent short-term outcomes.

Abstract
UniProtKB/Swiss-Prot, a curated protein database, and dictyBase, the Model Organism Database for Dictyostelium discoideum, have established a collaboration to improve data sharing. One of the major steps in this effort was the ‘Dicty annotation marathon’, a week-long exercise with 30 annotators aimed at achieving a major increase in the number of D. discoideum proteins represented in UniProtKB/Swiss-Prot. The marathon led to the annotation of over 1000 D. discoideum proteins in UniProtKB/Swiss-Prot. Concomitantly, there were a large number of updates in dictyBase concerning gene symbols, protein names and gene models. This exercise demonstrates how UniProtKB/Swiss-Prot can work in very close cooperation with model organism databases and how the annotation of proteins can be accelerated through those collaborations.
