Transapical aortic valve replacement in extreme-risk patients: outcome, risk factors and mid-term results.

OBJECTIVES: Transcatheter aortic valve replacement (TAVR) provides good results in selected high-risk patients. However, it is unclear whether this procedure carries advantages in extreme-risk profile patients with logistic EuroSCORE above 35%. METHODS: From January 2009 to July 2011, of a total number of 92 transcatheter aortic valve procedures performed, 40 'extreme-risk' patients underwent transapical TAVR (TA-TAVR) (EuroSCORE above 35%). Variables were analysed as risk factors for hospital and mid-term mortality, and a 2-year follow-up (FU) was obtained. RESULTS: The mean age was: 81 ± 10 years. Twelve patients (30%) had chronic pulmonary disease, 32 (80%) severe peripheral vascular disease, 14 (35%) previous cardiac surgery, 19 (48%) chronic renal failure (2 in dialysis), 7 (17%) previous stroke (1 with disabilities), 3 (7%) a porcelain aorta and 12 (30%) were urgent cases. Mean left ventricle ejection fraction (LVEF) was 49 ± 13%, and mean logistic EuroSCORE was 48 ± 11%. Forty stent-valves were successfully implanted with six Grade-1 and one Grade-2 paravalvular leakages (success rate: 100%). Hospital mortality was 20% (8 patients). Causes of death following the valve academic research consortium (VARC) definitions were: life-threatening haemorrhage (1), myocardial infarction (1), sudden death (1), multiorgan failure (2), stroke (1) and severe respiratory dysfunction (2). Major complications (VARC definitions) were: myocardial infarction for left coronary ostium occlusion (1), life-threatening bleeding (2), stroke (2) and acute kidney injury with dialysis (2). Predictors for hospital mortality were: conversion to sternotomy, life-threatening haemorrhage, postoperative dialysis and long intensive care unit (ICU) stay. Variables associated with hospital mortality were: conversion to sternotomy (P = 0.03), life-threatening bleeding (P = 0.02), acute kidney injury with dialysis (P = 0.03) and prolonged ICU stay (P = 0.02). Mean FU time was 24 months: actuarial survival estimates for all-cause mortality at 6 months, 1 year, 18 months and 2 years were 68, 57, 54 and 54%, respectively. Patients still alive at FU were in good clinical condition, New York Heart Association (NYHA) class 1-2 and were never rehospitalized for cardiac decompensation. CONCLUSIONS: TA-TAVR in extreme-risk patients carries a moderate risk of hospital mortality. Severe comorbidities and presence of residual paravalvular leakages affect the mid-term survival, whereas surviving patients have an acceptable quality of life without rehospitalizations for cardiac decompensation.

Head-to-head comparison of length of stay, patients' outcome and satisfaction in Switzerland before and after SwissDRG-Implementation in 2012 in 2012: an observational study in two tertiary university centers.

On 1 January 2012 Swiss Diagnosis Related Groups (DRG), a new uniform payment system for in-patients was introduced in Switzerland with the intention to replace a "cost-based" with a "case-based" reimbursement system to increase efficiency. With the introduction of the new payment system we aim to answer questions raised regarding length of stay as well as patients' outcome and satisfaction. This is a prospective, two-centre observational cohort study with data from University Hospital Basel and the Cantonal Hospital Aarau, Switzerland, from January to June 2011 and 2012, respectively. Consecutive in-patients with the main diagnosis of either community-acquired pneumonia, exacerbation of COPD, acute heart failure or hip fracture were included. A questionnaire survey was sent out after discharge investigating changes before and after SwissDRG implementation. Our primary endpoint was LOS. Of 1,983 eligible patients 841 returned the questionnaire and were included into the analysis (429 in 2011, 412 in 2012). The median age was 76.7 years (50.8% male). Patients in the two years were well balanced in regard to main diagnoses and co-morbidities. Mean LOS in the overall patient population was 10.0 days and comparable between the 2011 cohort and the 2012 cohort (9.7 vs 10.3; p = 0.43). Overall satisfaction with care changed only slightly after introduction of SwissDRG and remained high (89.0% vs 87.8%; p = 0.429). Investigating the influence of the implementation of SwissDRG in 2012 regarding LOS patients' outcome and satisfaction, we found no significant changes. However, we observed some noteworthy trends, which should be monitored closely.

Validated prediction of clinical outcome in sarcomas and multiple types of cancer on the basis of a gene expression signature related to genome complexity.

Sarcomas are heterogeneous and aggressive mesenchymal tumors. Histological grading has so far been the best predictor for metastasis-free survival, but it has several limitations, such as moderate reproducibility and poor prognostic value for some histological types. To improve patient grading, we performed genomic and expression profiling in a training set of 183 sarcomas and established a prognostic gene expression signature, complexity index in sarcomas (CINSARC), composed of 67 genes related to mitosis and chromosome management. In a multivariate analysis, CINSARC predicts metastasis outcome in the training set and in an independent 127 sarcomas validation set. It is superior to the Fédération Francaise des Centres de Lutte Contre le Cancer grading system in determining metastatic outcome for sarcoma patients. Furthermore, it also predicts outcome for gastrointestinal stromal tumors (GISTs), breast carcinomas and lymphomas. Application of the signature will permit more selective use of adjuvant therapies for people with sarcomas, leading to decreased iatrogenic morbidity and improved outcomes for such individuals.

Outcome and Prognostic Factors in Adenosquamous Carcinoma of the Head and Neck: A Multicenter Rare Cancer Network Study

Purpose/Objective(s): Adenosquamous carcinoma (AC) of the head and neck is a distinct entity first described in 1968. Its natural history is more aggressive than squamous cell carcinoma but this is based on very small series reported in the literature. The goal of this study was to assess the clinical profile, outcome, patterns of failure and prognostic factors in patients with AC of the head and neck treated by radiation therapy (RT) with or without chemotherapy (CT).Materials/Methods: Data from 18 patients with Stage I (n = 3), II (n = 1), III (n = 4), or IVa (n = 10) AC, treated between 1989 and 2009, were collected in a retrospective multicenter Rare Cancer Network study. Median age was 60 years (range, 48 - 73 years). Fourteen patients were male and 4 female. Risk factors, including perineural invasion, lymphangitis, vascular invasion, positive margins, were present in 83% of the patients. Tumor sites included oral cavity in 4, oropharynx in 4, hypopharynx in2, larynx in 2, salivary glands in 2, nasal vestibule in 2, nasopharynx in 1, and maxillary sinus in 1 patient. Surgery (S) was performed in all but 5 patients. S alone was performed in only 1 patient, and definitive RT alone in 3 patients. Fourteen patients received combined modality treatment (S+RT in 10, RT+CT in 2, and all of the three modalities in 2 patients). Median RT dose to the primary and to the nodes was 66 Gy (range, 50 - 72 Gy) and 53 Gy (range, 44 - 66 Gy), respectively (1.8 - 2.0 Gy/fr., 5 fr./ week). In 4 patients, the planning treatment volume included the primary tumor site only. Seven patients were treated with 2D RT, 7 with 3D conformal RT, and 2 with intensity-modulated RT.Results: After a median follow-up period of 38 months (range, 9 - 62 months), 8 patients developed distant metastases (lung, bone, mediastinum, and liver), 6 presented nodal recurrences, and only 4 had a local relapse at the primary site (all in-field recurrences). At last follow-up, 6 patients were alive without disease, 1 alive with disease, 9 died from progressive disease, and 2 died from intercurrent disease. The 3-year and median overall survival, disease-free survival (DFS) and locoregional control rates were 52% (95% confidence interval [CI]: 28 - 76%) and 39 months, 36% (95% CI: 13 - 49%) and 12 months, and 54% (95% CI: 26 - 82%) and 40 months, respectively. In multivariate analysis (Cox model), DFS was negatively influenced by the presence of extracapsular extension (p = 0.02) and advanced stage (IV versus I-III, p = 0.003).Conclusions: Overall prognosis of locoregionally advanced AC remains poor, and distant metastases and nodal relapse occur in almost half of the cases. However, local control is relatively good, and early stage AC patients had prolonged DFS when treated with combined modality treatment.

Predictive factors in the long term outcome in gastro-oesophageal reflux disease: six years follow up of 107 patients

There is little information concerning the long term outcome of patients with gastro-oesophageal reflux disease (GORD). Thus 109 patients with reflux symptoms (33 with erosive oesophagitis) with a diagnosis of GORD after clinical evaluation and oesophageal testing were studied. All patients were treated with a stepwise approach: (a) lifestyle changes were suggested aimed at reducing reflux and antacids and the prokinetic agent domperidone were prescribed; (b) H2 blockers were added after two months when symptoms persisted; (c) anti-reflux surgery was indicated when there was no response to (b). Treatment was adjusted to maintain clinical remission during follow up. Long term treatment need was defined as minor when conservative measures sufficed for proper control, and as major if daily H2 blockers or surgery were required. The results showed that one third of the patients each had initial therapeutic need (a), (b), and (c). Of 103 patients available for follow up at three years and 89 at six years, respective therapeutic needs were minor in 52% and 55% and major in 48% and 45%. Eighty per cent of patients in (a), 67% in (b), and 17% in (c) required only conservative measures at six years. A decreasing lower oesophageal sphincter pressure (p < 0.001), radiological reflux (p = 0.028), and erosive oesophagitis (p = 0.031), but not initial clinical scores, were independent predictors of major therapeutic need as shown by multivariate analysis. The long term outcome of GORD is better than previously perceived.

Cardiac and neurologic outcome of cardiac rhabdomyoma considerations for prenatal counseling

Abstract : Cardíac rhabdomyomas are benign cardiac tumors with few cardiac complications but with a known association to tuberous sclerosis that affects the neurologic outcome of the patients. Thís study analyses the long-term cardiac and neurological outcome of patients with cardiac rhabdomyomas in order to allow comprehensive prenatal counseling. qll prenatal and postnatal cases with echocardiographic diagnosis of cardiac rhabdomyomas encountered from August 1982 -September 2007 have been recorded. Independent factors, such às the number and the location of the tumors, have been analyzed for association with a diagnosis of tuberous sclerosis, in order to predict the cardiac and neurologic outcome of the patients. Cardiac complications include arrhythmias, outflow tract obstruction, secondary cardiogenic shock. Arrhythmias are the most often encountered problems during the neonatal period. Supraventricular tachycardia is the commonest rhythm disturbance identified. However, no specific dimension or location of the cardiac rhabdomyomas may predict the rhythm disturbances. The importance of the diagnosis of tuberous sclerosis in patients presenting with cardiac rhabdomyomas is exemplified by the neurodevelopmental complications showing 80% of cases with epilepsy and 63% of cases with a delayed development. The presence of multiple cardiac tumors in patients suggests a higher risk to be affected by tuberous sclerosis, compared to patients with a single tumor. Cardiac rhabdomyomas generally regress aftér birth and after the perinatal period cardiac-related problems are rare, but tuberous sclerosis and the associated neurodevelopmental complications dominate the clinical picture and should form an important aspect of the prenatal counseling of parents. Résumé : Les rhabdomyomes cardiaques sont des tumeurs cardiaques bénignes avec toutefois des complications. cardiaques possibles et surtout avec une association pour la sclérose tubéreuse de Bourneville qui détermine le pronostic neurologique. Cette étude présente une analyse du suivi cardiologique. et neurologique à long terme d'enfants avec un diagnostic de rhabdomyomes cardiaques dans le but de mieux informer les parents lors de la consultation anténatale. L'ensemble des cas de rhabdomyomes cardiaques diagnostiqués au moyen de l'échocardiographie pendant la période anténatale ainsi que postnatale a été répertorié d'août 1982 à septembre 2007. Des facteurs indépendants, tels que le nombre et la localisation des tumeurs, ont été analysés pour leur association avec le diagnostic de la sclérose tubéreuse de Bourneville, afin de prédire le pronostic cardiaque et neurologique de ces patients. Les complications cardiaques retrouvées sont les arythmies, les obstructions des voies d'éjection ventriculaire et le choc cardiogène secondaire. Les arythmies sont les problèmes les plus fréquemment rencontrés pendant la période néonatale.. La tachycardie supraventriculaire est le trouble de rythme le plus souvent identifié. Néanmoins, il n'y a pas de dimension ou de localisation.- spécifique d'un rhabdomyome cardiaque qui pourrait prédire ces troubles du rythme. L'importance de l'association au diagnostic de la sclérose tubéreuse de Bourneville chez les patients atteints de rhabdomyomes est démontrée à travers les complications du développement neurologique avec une attéinte épileptique dans 80% des cas ainsi qu'un retard de développement dans 63% des cas. La présence de multiples tumeurs cardiaques chez un patient suggère un risque accru d'être atteint de la sclérose tubéreuse de Bourneville comparé à un patient atteint d'une tumeur unique. Les rhabdomyomes cardiaques régressent après la naissance et après la période périnatale les complications cardiaques deviennent rares. Toutefois, l'association à la sclérose tubéreuse de Bourneville domine le tableau clinique avec des complications au niveau du développement neurologique et formé donc un aspect important lors de la consultation anténatale.

Frequencies of circulating MDSC correlate with clinical outcome of melanoma patients treated with ipilimumab.

Metastatic melanoma has a poor prognosis with high resistance to chemotherapy and radiation. Recently, the anti-CTLA-4 antibody ipilimumab has demonstrated clinical efficacy, being the first agent to significantly prolong the overall survival of inoperable stage III/IV melanoma patients. A major aim of patient immune monitoring is the identification of biomarkers that predict clinical outcome. We studied circulating myeloid-derived suppressor cells (MDSC) in ipilimumab-treated patients to detect alterations in the myeloid cell compartment and possible correlations with clinical outcome. Lin(-) CD14(+) HLA-DR(-) monocytic MDSC were enriched in peripheral blood of melanoma patients compared to healthy donors (HD). Tumor resection did not significantly alter MDSC frequencies. During ipilimumab treatment, MDSC frequencies did not change significantly compared to baseline levels. We observed high inter-patient differences. MDSC frequencies in ipilimumab-treated patients were independent of baseline serum lactate dehydrogenase levels but tended to increase in patients with severe metastatic disease (M1c) compared to patients with metastases in skin or lymph nodes only (M1a), who had frequencies comparable to HD. Interestingly, clinical responders to ipilimumab therapy showed significantly less lin(-) CD14(+) HLA-DR(-) cells as compared to non-responders. The data suggest that the frequency of monocytic MDSC may be used as predictive marker of response, as low frequencies identify patients more likely benefitting from ipilimumab treatment. Prospective clinical trials assessing MDSC frequencies as potential biomarkers are warranted to validate these observations.

Long-term Outcome and Late Side Effects in Endometrial Cancer Patients Treated with Surgery and Postoperative Radiation Therapy.

BACKGROUND: We retrospectively reviewed the long-term outcome and late side effects of endometrial cancer (EC) patients treated with different techniques of postoperative radiotherapy (PORT). METHODS: Between 1999 and 2012, 237 patients with EC were treated with PORT. Two-dimensional external beam radiotherapy (2D-EBRT) was used in 69 patients (30 %), three-dimensional EBRT (3D-EBRT) in 51 (21 %), and intensity-modulated RT (IMRT) with helical Tomotherapy in 47 (20 %). All patients received a vaginal brachytherapy (VB) boost. Seventy patients (29 %) received VB alone. RESULTS: After a median of 68 months (range, 6-154) of follow-up, overall survival was 75 % [95 % confidence interval (CI), 69-81], disease-free survival was 72 % (95% CI, 66-78), cancer-specific survival was 85 % (95 % CI, 80-89), and locoregional control was 86 % (95 % CI, 81-91). The 5-year estimates of grade 3 or more toxicity and second cancer rates were 0 and 7 % (95 % CI, 1-13) for VB alone, 6 % (95 % CI, 1-11) and 0 % for IMRT + VB, 9 % (95 % CI, 1-17) and 5 % (95 % CI, 1-9) for 3D-EBRT + VB, and 22 % (95 % CI, 12-32) and 12 % (95 % CI, 4-20) for 2D-EBRT + VB (P = 0.002 and P = 0.01), respectively. CONCLUSIONS: Pelvic EBRT should be tailored to patients with high-risk EC because the severe late toxicity observed might outweigh the benefits. When EBRT is prescribed for EC, IMRT should be considered, because it was associated with a significant reduction of severe late side effects.

Do brief alcohol motivational interventions work like we think they do?

BACKGROUND: Questions remain about how brief motivational interventions (BMIs) for unhealthy alcohol use work, and addressing these questions may be important for improving their efficacy. Therefore, we assessed the effects of various characteristics of BMIs on drinking outcomes across 3 randomized controlled trials (RCTs). METHODS: Audio recordings of 314 BMIs were coded. We used the global rating scales of the Motivational Interviewing Skills Code (MISC) 2.1: counselor's acceptance, empathy, and motivational interviewing (MI) spirit, and patient's self-exploration were rated. MI proficiency was defined as counselor's rating scale scores ≥5. We also used the structure, confrontation, and advice subscale scores of the Therapy Process Rating Scale and the Working Alliance Inventory. We examined these process characteristics in interventions across 1 U.S. RCT of middle-aged medical inpatients with unhealthy alcohol use (n = 124) and 2 Swiss RCTs of young men with binge drinking in a nonclinical setting: Swiss-one (n = 62) and Swiss-two (n = 128). We assessed the associations between these characteristics and drinks/d reported by participants 3 to 6 months after study entry. RESULTS: In all 3 RCTs, mean MISC counselor's rating scales scores were consistent with MI proficiency. In overdispersed Poisson regression models, most BMI characteristics were not significantly associated with drinks/d in follow-up. In the U.S. RCT, confrontation and self-exploration were associated with more drinking. Giving advice was significantly associated with less drinking in the Swiss-one RCT. Contrary to expectations, MI spirit was not consistently associated with drinking across studies. CONCLUSIONS: Across different populations and settings, intervention characteristics viewed as central to efficacious BMIs were neither robust nor consistent predictors of drinking outcome. Although there may be alternative reasons why the level of MI processes was not predictive of outcomes in these studies (limited variability in scores), efforts to understand what makes BMIs efficacious may require attention to factors beyond intervention process characteristics typically examined.

Évaluation du suivi clinique des prothèses totales du genou [Total knee arthroplasty outcome assessment]

L'évaluation des résultats des arthroplasties totales du genou demande une évaluation du geste thérapeutique ou clinique, mais doit également tenir compte de l'impact de ce geste sur l'état de santé global du patient (somatique, psychologique, social) et intégrer son degré de satisfaction. La complexité croissante des instruments de mesure du suivi a de quoi décourager le chirurgien praticien déjà surchargé par son activité clinique quotidienne. L'apparition des scores, des études prospectives et des analyses statistiques, telles les courbes de survie, ont certainement permis une appréciation plus objective de nos résultats, tout en accroissant nos connaissances et en améliorant notre pratique quotidienne. La question aujourd'hui n'est plus de savoir si un suivi clinique de nos patients est utile, mais plutôt de choisir les bons instruments et de définir les buts de l'analyse tout en cherchant comment implanter cette démarche de manière réaliste dans nos pratiques. Les scores classiques, aussi imparfaits soient-ils, restent pour l'instant utiles. Largement diffusés à travers le monde, appliqués de manière prospective, ces outils de suivi orientés vers la clinique et la radiologie sont le fondement du suivi prospectif des implants. Au quotidien, ils permettent un suivi en temps réel des implants d'un service ou d'une institution. Cependant, leur faiblesse intrinsèque résidant dans l'inaptitude à saisir le point de vue du patient, il semble inéluctable d'y adjoindre des instruments psychométriques. Dans l'avenir, la recherche devrait se concentrer vers le développement d'outils adaptés, capables de cerner avec une plus grande précision l'attente des patients et de technologies accessibles à chaque praticien pour mesurer objectivement les capacités fonctionnelles de leurs patients avec plus d'acuité. Le développement de systèmes permettant une évaluation objective de la fonction quotidienne du patient revêt un intérêt tout particulier. Parallèlement, un effort doit être fait au niveau des sociétés spécialisées nationales et internationales pour harmoniser leurs protocoles de suivi.

The role of alliance in the relationship between therapist competence and outcome in brief psychodynamic psychotherapy.

Therapist competence is a key variable for psychotherapy research. Empirically, the relationship between competence and therapeutic outcome has shown contradictory results and needs to be clarified, especially with regard to possible variables influencing this relationship. A total of 78 outpatients were treated by 15 therapists in a very brief 4-session format, based on psychoanalytic theory. Data were analyzed by means of a nested design using hierarchical linear modeling. No direct link between therapist competence and outcome has been found, however, results corroborated the importance of alliance patterns as moderator in the relationship between therapist competence and outcome. Only in dyads with alliance change over the course of treatment was it clear that competence is positively related to outcome. These findings are discussed with regard to the importance for outcome of therapist competence and alliance construction processes.

Critical evaluation of outcome scales assessment of lateral ankle ligament reconstruction.

BACKGROUND: Outcome following foot and ankle surgery can be assessed by disease- and region-specific scores. Many scoring systems exist, making comparison among studies difficult. The present study focused on outcome measures for a common foot and ankle abnormality and compared the results obtained by 2 disease-specific and 2 body region-specific scores. METHODS: We reviewed 41 patients who underwent lateral ankle ligament reconstruction. Four outcome scales were administered simultaneously: the Cumberland Ankle Instability Tool (CAIT) and the Chronic Ankle Instability Scale (CAIS), which are disease specific, and the American Orthopedic Foot & Ankle Society (AOFAS) hindfoot scale and the Foot and Ankle Ability Measure (FAAM), which are both body region-specific. The degree of correlation between scores was assessed by Pearson's correlation coefficient. Nonparametric tests, the Kruskal-Wallis and the Mann-Whitney test for pairwise comparison of the scores, were performed. RESULTS: A significant difference (P < .005) was observed between the CAIS and the AOFAS score (P = .0002), between the CAIS and the FAAM 1 (P = .0001), and between the CAIT and the AOFAS score (P = .0003). CONCLUSIONS: This study compared the performances of 4 disease- and body region-specific scoring systems. We demonstrated a correlation between the 4 administered scoring systems and notable differences between the results given by each of them. Disease-specific scores appeared more accurate than body region-specific scores. A strong correlation between the AOFAS score and the other scales was observed. The FAAM seemed a good compromise because it offered the possibility to evaluate the patient according to his or her own functional demand. CLINICAL RELEVANCE: The present study contributes to the development of more critical and accurate outcome assesment methods in foot and ankle surgery.
