Abstract
Abstract
Background
Polypharmacy is common in older adults with cognitive impairment and multiple chronic conditions increasing their risks of adverse drug events, hospitalization, further cognitive decline and death and leading to higher health care costs. Deprescribing, the process of reducing or stopping potentially inappropriate medications may improve outcomes. The OPTIMIZE trial examined whether educating and activating patients, family and clinicians about deprescribing reduces number of medications for older adults with cognitive impairment and multiple chronic conditions. Acceptability and challenges of intervention delivery in this vulnerable population are not well understood.
Methods
We explored mechanisms of intervention effectiveness through post hoc qualitative interviews and surveys with 15 patients, 7 family caregivers, and 28 clinicians. We assessed accessibility and delivery of materials as well as the ability of the materials to facilitate conversations and influence decisions around deprescribing.
Results
Acceptance of the intervention was affected by contextual factors including cognition and prior knowledge of deprescribing. Positive effects of the intervention included patients scheduling specific appointments to discuss deprescribing and providers being prompted to consider deprescribing. Recollection of intervention materials by patients was inconsistent but highest shortly after intervention delivery. Short clinic visit times remained the largest clinician barrier to deprescribing.
Conclusion
Our work identifies key learnings in intervention roll out which can guide future scaling of our intervention and other pragmatic deprescribing intervention studies in patients with cognitive impairment. We highlight the critical roles of both timing and repetition in intervention delivery to cognitively impaired populations as well as the barrier to deprescribing posed by short clinic consultation time. Our success in activating deprescribing conversations in this population highlights the need to incentivize medical professionals and health systems to incorporate deprescribing into routine clinical practice and expand proven interventions to other vulnerable populations.

Abstract
Abstract
Background
Recent evidence has shown that patients with acute SARS-CoV-2 infection might present symptoms of infection a long time after a recovery.
Purpose
To investigate the risk factors and assess the utility of spiroergometry parameters in differential diagnosing patients presenting the symptoms (dyspnea, fatique, pain in chest, muscle pain, cognitive impairment, taste and smell disturbances) persisting for a few months after recovery from COVID 19 (symptoms of long COVID).
Methods and results
The 146 patients (pts) with normal left ventricular ejection fraction and without respiratory diseases, hospitalised in Cardiology Department recovering from COVID-19 at three to six months after confirmed diagnosis were included. The clinical examination, laboratory results, echocardiography using Vivid E95–GE Healthcare, non-invasive body mass analysis using Body Composition Analyzer (Tanita Pro), spiroergometry using The MetaSoft® Studio application were analyzed. The subjects were divided into the two following groups: group demonstrating long COVID symptoms (i.e. suffering from one of the following dyspnea, fatique, pain in chest, muscle pain, cognitive impairment, taste or smell disturbances) [N=44 pts] and the group without long COVID symptoms [N=102 pts]. Pts with long COVID symptoms presented significantly higher age (58 versus [vs] 44 years; p<0.0001), higher metabolic age (53 vs 45 years; p=0.01), higher left atrial diameter (37 vs 35 mm; p=0.04), higher left ventricular mass index (LVMI) (83 vs 74 g/m2, p=0.03), higher E/E' (7.3 vs 6; p<0.001) compared to control group. In CPET long COVID pts presented lower forced vital capacity (FVC) (3.6 vs 4.3 L; p=0.009), lower maximal oxygen consumption measured during incremental exercise indexed per kilogram (VO2max) (21 vs 23 ml/min/kg; p=0.04), lower respiratory exchange ratio (RER) (1.0 vs 1.1; p=0.04); lower forced expiratory volume in one second (FEV1) (2.9 vs 3.25 L; p=0,03); higher ratio of forced expiratory volume in one second to forced vital capacity (FEV1/FVC) (106 vs 100%; p=0.0002) – Figure 1, there were no significant changes in electrocardiogram between groups. The laboratory results pointed that pts with long COVID symptoms had also lower rate of red blood cells (RBC) (4,4 vs 4,6 mln; p=0.01); higher level of glucose (92 vs 90 mg%; p=0.02); lower glomerular filtration rate (GFR) estimate by Modification of Diet in Renal Disease (MDRD) (88 vs 95; p=0.02); higher level of hypersensitive cardiac Troponin T (hsTnT) (6.1 vs 3.9 ng/L; p=0.03). The parameters significant in univariate analyses were included to the multivariate model. The results of multiple logistic regression were as follows: age (OR 4.6, 95% CI: 1.7–11.5; p=0.001) and LVMI (OR 2.5, 95% CI: 1.0–6.6; p=0.04).
Conclusions
Persistent symptoms in long COVID can mimic those of cardiovascular disease. Spiroergometric parameters are useful in making a proper diagnosis.

Abstract
Abstract
Background
Exercise intolerance de novo is one of the most common reported symptoms in patients (pts) recovering from COVID-19.
Purpose
The present study determines etiological and pathophysiological factors influencing the mechanism of exercise intolerance in the COVID-19 survivors. Therefore, the factors affecting percent predicted oxygen uptake at peak exercise VO2 (%VO2pred) in pts after COVID-19 with normal left ventricular ejection fraction were assessed.
Methods and results
The 120 consecutive patients from the Department of Cardiology recovering from COVID-19 at three to six months after confirmed diagnosis were included. The clinical examinations, laboratory test results, echocardiography using Vivid E95 – GE Healthcare, non-invasive body mass analysis using Body Composition Analyzer (Tanita Pro), and spiroergometry using The MetaSoft® Studio application were analysed. The subjects were divided into the two following groups: study i.e. pts with worse oxygen uptake (%VO2pred <80%; N=47) and control including these cases with %VO2pred ≥80% (N=73) – Table 1. Pts with %VO2pred <80% presented significantly lower global peak systolic strain (GLPS) [p=0.03], tricuspid annular plane systolic excursion (TAPSE) [p=0.002] and late diastolic filling velocity (A) [p=0.004] compared to controls – Figure 1. The male gender (p=0.007) and the percent of total body water content (TBW %) (p=0.02) were significantly higher in study in comparison to the control group. The results of multiple logistic regression model independently associated with %VO2pred were as follows: A (OR 0.4, 95% CI: 0.17–0.95; p=0.03) and gender (OR 2.52, 95% CI: 1.07–5.91; p=0.03).
Conclusions
Males have over twice risk of persistent limited exercise tolerance after COVID-19 infection than females. The lower late diastolic filling velocity, tricuspid annular plane systolic excursion, worse global peak systolic strain, and hydration status are connected with limited exercise tolerance after COVID-19 in patients with normal left ventricular ejection fraction.

Abstract
Abstract
Background
Among many complications of coronavirus disease 2019 (COVID-19) there is a wide range of cardiovascular (CV) problems ranging from mild to severe ones. Even asymptomatic patients and those with mild course of COVID-19 may develop severe CV complications. Factors leading to such state have not been extensively studied so far.
Purpose
We aimed to assess which factors were linked to the severe complications of COVID-19.
Methods
We included 200 consecutive patients admitted to the Department of Cardiology and Adult Congenital Heart Diseases of the Polish Mother's Memorial Research Institute (PMMHRI) due to post-Covid cardiovascular complications. SARS-CoV2 infection was confirmed with real-life PCR testing. Laboratory tests, 24-hour ECG monitoring and echocardiography were performed in all patients from the investigated group. For the purposes of our study severe complications were defined as: myocarditis, a decrease of ejection fraction >10% from the pre-disease value, thromboembolic complications, angina pectoris requiring myocardial revascularization and the new onset of atrial fibrillation of supraventricular tachycardia. Some patients presented more than one of the above. Statistical analysis was performed using the software Statistica v.13 (TIBCO Software Inc., Palo Alto, CA, USA). Data were presented as mean ±SD or median (25th-75th percentile) for continuous variables and as proportions for categorical variables. Comparisons between groups were performed using Student's t-test for independent variables and the Mann-Whitney U test or χ2 test with Yates's correction, as appropriate. For all calculations p-values <0.05 were considered statistically significant.
Results
Finally, we included 200 consecutive patients (aged 54±16 years, 76 males – 38%), hospitalized for COVID-19 complications after a median 3 (2–6) months following the acute phase of infection. On admission patients presented with dyspnea (23%), impairment of exercise tolerance (47%), chest pain (32%), increase in blood pressure (29%), palpitations (25%), weight loss (13%), brain fog (6%), general malaise (11%), headache (5%), limb pain (13%), swelling (14%). Severe complications of COVID-19 were diagnosed in 31 patients (16%).Taking into consideration symptoms, the presence of severe COVID-19 complications was significantly associated with dyspnoea and deterioration of exercise tolerance. In comparison to patients with mild complications, severe ones were linked to age (the older patients, the higher risk), previous history of heart failure and diabetes mellitus. We did not observe statistically significant differences in severity of complications depending on smoking status (Tables 1 and 2).
Conclusions
Previous history of heart failure and diabetes mellitus as well as symptoms (dyspnoea and deterioration of exercise tolerance) along with older age are related to more severe complications following COVID-19.

Abstract
Abstract
Background/Introduction
Heart failure (HF) and atrial fibrillation (AF) are two conditions that are likely to dominate the next years of cardiovascular (CV) care. These diseases frequently coexist and they can beget one another due to similar risk factors and similar pathophysiology.
Purpose
The aim of the study was to assess the relationship of dehydration, body mass index (BMI) and other indices with the occurrence of AF in HF patients.
Methods
The study included 113 patients [median age 64 years; 57.52% male] hospitalized due to HF. Baseline demographics, body mass analysis, echocardiographic results, key cardiopulmonary exercise test (CPET) parameters, six minute walk distance (6MWD) and Kansas City Cardiomyopathy Questionnaire (KCCQ) score were assessed.
Results
Of all patients, 23 (20.35%) had AF, and 90 (79.65%) had sinus rhythm (SR). Patients with AF were older (med. 66 vs 64 years; p=0.039), with higher BMI (32.02 vs. 28.51 kg/m2; p=0.017) and percentage of fat content (37.0 vs. 27.9%, p=0.014). They were more dehydrated, with a lower percentage of total body water (TBW%) (45.7 vs 50.0%; p=0.022). Clinically, patients with AF had more often higher New York Heart Association (NYHA) class (III vs II; p<0.001), shorter 6MWD (median 292.35 vs 378.4 m; p=0.001) and a lower KCCQ overall summary score (52.60 vs 73.96 points; p=0.002). Patients with AF had significantly lower exercise capacity as measured by peak oxygen consumption (peak VO2) (0.92 vs 1.26 mL/min, p=0.016), peak VO2/kg (11 vs. 15 mL/kg/min; p<0.001), and percentage of predicted VO2max (pp-peak VO2) (62.5 vs 70.0; p=0.010). We also found VE/VCO2 (med.33.85 vs 32.20; p=0.049) to be higher and peak oxygen pulse (8.5 vs 11 mL/beat; p=0.038) to be lower in patients with AF than in patients without AF. In a multiple logistic regression model higher BMI (OR 1.23 per unit increase, p<0.001) and higher left atrial volume index (LAVI) (OR 1.07 per unit increase, p=0.03), lower tricuspid annular plane systolic excursion (TAPSE) (OR 0.74 per unit increase, p=0.03) and lower TBW% in body mass analysis (OR 0.90 per unit increase, p=0.03) were independently related to AF in patients with HF.
Conclusions
Increased volume of left atrium and right ventricular systolic dysfunction are well-known predictors of AF occurrence in patients with HF, but hydration status and increased body mass also seem to be important factors of AF in HF patients.

Abstract
Abstract
Purpose
The aim was to identify factors influencing maximal oxygen uptake (VO2max) and early identification of hypertensive women at risk of heart failure (HF).
Methods
The 185 consecutive females with controlled hypertension were divided according VO2max quartiles. The patients underwent echocardiography, non-invasive body mass analysis, spiroergometry and hemodynamic parameters. Regression analyses determined predictors of the lowest VO2max (quartile 1: VO2max <17 ml/kg/min).
Results
Females with the worst oxygen consumption had significantly higher level of high sensitive cardiac Troponin T (hs-cTnT) [p=0.001], higher values of the left atrial (LA) volume, late diastolic mitral annulus velocity (A'), ratio of peak velocity of early diastolic transmitral flow to peak velocity of early diastolic mitral annular motion (E/E') [p=0.0003, p=0.02, p=0.04; respectively] and lower E' [p=0.001] compared to controls. Women with the worst exercise capacity had higher body mass index (BMI) and fat content (kg and %) [p<0.0001], higher fat free mass (FFM) (kg) [p<0.0001], higher total body water content (TBW) [p=0.0002] as well as extracellular body water content (ECW) [p<0.0001] and intracellular body water content (ICW) [p=0.005], ECW/TBW x 100% [p<0.0001] and metabolic age [p<0.0001] compared to counterparts. In a multiple logistic regression model independently associated with VO2max were: ECW/TBW x 100% (OR 4.45, 95% CI: 1.77–11.21; p=0.002) Figure 1, BMI (OR 7.11, 95% CI: 2.01–25.11; p=0.002) Figure 2 and hs-cTnT level (OR 2.69, 95% CI: 1.23–5.91; p=0.013).
Conclusions
High-sensitivity cardiac troponin may serve as early biomarker of heart failure in hypertensive women. Hydration status should be considered in overall hypertensive women care. There is an importance of body mass compartments analysis in early identification of hypertensive females at risk of heart failure.

Abstract
In the paper, we provide the construction of a coincidence degree being a homotopy invariant detecting the existence of solutions of equations or inclusions of the form Ax ∈ F(x), x ∈ U, where [Formula: see text] is an m-accretive operator in a Banach space E, [Formula: see text] is a weakly upper semicontinuous set-valued map constrained to an open subset U of a closed set K ⊂ E. Two different approaches are presented. The theory is applied to show the existence of non-trivial positive solutions of some nonlinear second-order partial differential equations with discontinuities. This article is part of the theme issue 'Topological degree and fixed point theories in differential and difference equations'.

Abstract
Background Most individuals with dementia or mild cognitive impairment (MCI) have multiple chronic conditions (MCC). The combination leads to multiple medications and complex medication regimens and is associated with increased risk for significant treatment burden, adverse drug events, cognitive changes, hospitalization, and mortality. Optimizing medications through deprescribing (the process of reducing or stopping the use of inappropriate medications or medications unlikely to be beneficial) may improve outcomes for MCC patients with dementia or MCI. Methods With input from patients, family members, and clinicians, we developed and piloted a patient-centered, pragmatic intervention (OPTIMIZE) to educate and activate patients, family members, and primary care clinicians about deprescribing as part of optimal medication management for older adults with dementia or MCI and MCC. The clinic-based intervention targets patients on 5 or more medications, their family members, and their primary care clinicians using a pragmatic, cluster-randomized design at Kaiser Permanente Colorado. The intervention has two components: a patient/ family component focused on education and activation about the potential value of deprescribing, and a clinician component focused on increasing clinician awareness about options and processes for deprescribing. Primary outcomes are total number of chronic medications and total number of potentially inappropriate medications (PIMs). We estimate that approximately 2400 patients across 9 clinics will receive the intervention. A comparable number of patients from 9 other clinics will serve as wait-list controls. We have > 80% power to detect an average decrease of − 0.70 (< 1 medication). Secondary outcomes include the number of PIM starts, dose reductions for selected PIMs (benzodiazepines, opiates, and antipsychotics), rates of adverse drug events (falls, hemorrhagic events, and hypoglycemic events), ability to perform activities of daily living, and skilled nursing facility, hospital, and emergency department admissions. Discussion The OPTIMIZE trial will examine whether a primary care-based, patient- and family-centered intervention educating patients, family members, and clinicians about deprescribing reduces numbers of chronic medications and PIMs for older adults with dementia or MCI and MCC.

Abstract
Background
Incidental findings in echocardiography performed from other indications are not always able to explain the patient condition as well as the observed pathology. However, review of literature, helps to find the most possible explanation. We present a case study of a patient with our proposal of possible diagnosis.
Case report
28-year old female with hypothyroidism and no other concomitant diseases presented with easy fatigue. Exercise stress test was clinically and ECG negative with 12,8 METs. Transthoracic echocardiography showed normal size of heart structures with preserved systolic and diastolic function of both left and right chamber. The only abnormality was a cystic structure of 44x31x34 cm in interatrial septum which was protruding to both left and right atrium and was not affecting the blood flow with normal gradients. We did not find any signs of inflammation nor infiltration to the heart walls. There was no flow inside the cyst with the use of colour Doppler. The structure had homogenous echolucency with very thin walls and a septum inside. As we did not find any connection between the cyst and the atriums we considered it as not harmful in terms of a risk of embolization. Patient was hemodynamically stable, there was no history of neurological dysfunctions nor atrioventricular conduction disturbances. Taking into account possible diagnoses for that patient we decided to schedule the patient for follow-ups. Ten years observation period confirmed that that our approach was proper. Serial echocardiographic studies showed no change in the cyst. In this year we performed multimodality imaging with CT and MRI, which showed the same views as echocardiography.
Discussion
The most possible diagnose for our patient is a bronchogenic cyst, a very rare congenital bronchopulmonary malformation of the foregut that is usually found incidentally with mostly asymptomatic benign course. Also the localization of the cyst confirms that diagnosis. Nevertheless the final diagnosis would be possible only in histopathological study.
The differential diagnosis should include a cystic myxoma and echinococcosis. However the structure is not polycystic and seems to have homogenous echolucency. We ruled out the blood cyst because of the lack of typical localization and connection to valves.
As long as the patient remains asymptomatic surgical resection remains controversial.

Abstract
Abstract
The Taussig –Bing anomaly is a rare congenital heart malformation that was first described in 1949 by Helen B. Taussig and Richard J. Bing. It is characterized by the presence of a large subpulmonic ventricular septal defect (VSD) and, usually, side-by-side great vessels that arise entirely from the right ventricle. Unlike TGA with VSD, this anomaly is characterized by the presence of a bilateral conus and the absence of aortomitral continuity. Increased pulmonary blood flow leads to early onset of pulmonary vascular disease, hence repair in the early infancy period is recommended. VSD closure combined with arterial switch is currently the preferred procedure. Lecompte introduced a new surgical technique that includes extensive resection of the conal septum and direct reimplantation of the pulmonary trunk on the superior margin of the right ventricular infundibulotomy.
We present case of 18-year-old male patient with Taussig-Bing anomaly after pulmonary artery binding and closure of ductus arteriosus when one year old and after anatomical Jatene correction with modified Lacompte procedure at the age of two years. The patient was admitted to our Department in October 2018 after episode of sudden cardiac arrest in the mechanism of ventricular fibrillation. Echocardiographic examination revealed preserved systolic function of both ventricles (LVEF 62%, TAPSE 25 mm, RV S’ 13cm/s) without contractility disturbances. The enlarged and hypertrophic left ventricle consists of the primary cavity connecting by VSD (size 39 mm) with a fragment of the right ventricle separated from the rest of the right ventricle by a patch with Gore-Tex acting as a ventricular septum - without any leakage features (Figure 1A and 1B). We noticed also enlarged left atrium, increased diameter of neoaorty bulb (50 mm), severe neoaortic regurgitation (AV max: 1,85 m/s, ERO-70, VC-8mm, PHT 327 ms) (Figure 1C), moderate mitral regurgitation (type I according Carpentier) (Figure1D). On 8.01.2019 a subcutaneous ICD Boston Scientific Emblem with a subcutaneous defibrillation electrode was implanted. In performed spiroergometry decreased peak oxygen consumption (2,24 ml/min/kg), the study was stopped because of fatique, assessed expiratory exchange ratio, and episode of nsVT. After decision of Heart Team the patient is qualified for surgical treatment of valve defects.

Abstract
Abstract
Background
Thromboembolic complications following Fontan procedure are one of the major causes of mortality and morbidity among patients with univentricular heart. We may classify thromboembolic complications into two groups: systemic- and nonsystemic. We present a case of a patient with a manifestation of both.
Case report
24-year old female, foreign student was admitted to Ophthalmology Department due to sudden blindness of the left eye. Performed studies revealed embolus in the left central retinal artery. Because the patient had the history of congenital heart defect she was referred to our department. Analysis of medical documentation showed that the patient has combined congenital heart defect including right ventricle hypoplasia, tricuspid atresia, pulmonic stenosis, ventricular septal defect, atrial septal defect and persistent ductus arteriosus. She had a history of two surgeries: modified left-side Blalock-Tausing connection (in 4th month of life) and total cavo-pulmonary connection with the closure of Blalock-Tausing and excision of interatrial septum (in 2,5 year of life). On admission she presented with left-eye blindness. She had no dyspnoea or palpitations. However she reported very severe migraines from a few days preceding the admission to hospital. Echocardiography revealed tricuspid atresia, hypoplastic right ventricle, preserved systolic and diastolic function of left ventricle, atrial septal defect with no restriction. We observed enlarged diameter of vena cava inferior with no respirophasic variations and massive thrombus in inside with very low flow. The connection between inferior vena cava and right pulmonary artery was working properly with no visible fenestration. We also observed a winding vessel between ascending aorta and truncus pulmonalis/pulmonary artery with continuous flow of blood from left to right side. Computer tomography confirmed the diagnosis of massive thrombosis of vena cava inferior. Patient had anticoagulation started. Two days later we the flow in inferior vena cava returned – we did not observe any thrombus. Patient was referred to catheterization and had chronic anticoagulation initiated.
Three months follow-up revealed no changes in clinical condition of a patient.
Discussion
The palliative Fontan operation predispose to the increased risk of thromboembolic complication. Despite the risk factors of such complications have been identified, there are no guidelines about prophylactic anticoagulation in that group of patients. As a result, chronic anticoagulation is initiated in patients who have other indications e.g. atrial fibrillation. It seems that it would be beneficial to define the group of patients after Fontan procedure with indications to chronic anticoagulation therapy despite arrhythmias.

Abstract
Backround The primary aim of this study was to investigate information needs and treatment preferences of patients with ovarian cancer, focusing especially on physician-patient relationship and treatment. Patients and methods A questionnaire was developed based on the experiences of the national German survey 'Expression II', and was provided to patients with ovarian cancer either at initial diagnosis or with recurrent disease via Internet (online-version) or as print-out-version. Results From December 2009 to October 2012, a total of 1830 patients with ovarian cancer from eight European countries (Austria, Belgium, France, Germany, Italy, Poland, Romania, Spain) participated, 902 (49.3%) after initial diagnosis and 731 (39.9%) with recurrent ovarian cancer. The median age was 58 years (range 17-89). Nearly all patients (96.2%) had experienced upfront surgery followed by first-line chemotherapy (91.8%). The majority of patients were satisfied with the completeness and comprehensibility of the explanation about the diagnosis and treatment options. The three most important aspects, identified by patients to improve the treatment for ovarian cancer included: 'the therapy should not induce alopecia' (42%), 'there must be more done to counter fatigue' (34.5%) and 'the therapy should be more effective' (29.7%). Out of 659 (36%) patients, who were offered participation in a clinical trial, 476 (26%) were included. Conclusion This study underlines the high need of patients with ovarian cancer for all details concerning treatment options irrespective of their cultural background, the stage of disease and the patient's age. Increased information requirements regarding potential side effects and treatment alternatives were recorded. Besides the need for more effective therapy, alopecia and fatigue are the most important side effects of concern to patients.

Abstract
BACKGROUND Mastocytosis is characterised by the presence of abnormal quantities of mastocytes in one or more organs. Although it occurs in systemic forms of mastocytosis, isolated skin involvement is the predominant presentation, particularly in children, in the form of more or less extensive though non-systematic lesions. Herein, we report a case of maculopapular cutaneous mastocytosis that is unusual in terms of its metameric topography. PATIENTS AND METHODS A 16-year-old youth presented with an erythematous maculopapular rash of 18 months' duration and involving pruritic inflammatory episodes strictly localised in segment T8 to the left. The skin biopsy showed a significant increase in the number of dermal mastocytes (CD117+). No KIT mutations were found in the skin lesions nor in the unimpaired skin of the opposite side. Further investigations ruled out systemic mastocytis. DISCUSSION Herein, we report a case of cutaneous mastocytosis that is unusual in terms of its metameric disposition. There have been only two previous reports of segmental cutaneous mastocytis. The two pathological hypotheses involved precessional dermatitis that renders the skin surface susceptible to homing, and somatic mosaicism (type 1) with local mastocyte proliferation.

Abstract
Objective A weight loss maintenance trial involving weight loss prior to randomization is challenging to implement due to the potential for dropout and insufficient weight loss. We examined rates and correlates of non‐initiation, dropout, and insufficient weight loss during a weight loss maintenance trial. Methods The MAINTAIN trial involved a 16‐week weight loss program followed by randomization among participants losing at least 4 kg. Psychosocial measures were administered during a screening visit. Weight was obtained at the first group session and 16 weeks later to determine eligibility for randomization. Results Of 573 patients who screened as eligible, 69 failed to initiate the weight loss program. In adjusted analyses, failure to initiate was associated with lower age, lack of a support person, and less encouragement for making dietary changes. Among participants who initiated, 200 dropped out, 82 lost insufficient weight, and 222 lost sufficient weight for randomization. Compared to losing sufficient weight, dropping out was associated with younger age and tobacco use, whereas losing insufficient weight was associated with non‐White race and controlled motivation for physical activity. Conclusions Studies should be conducted to evaluate strategies to maximize recruitment and retention of subgroups that are less likely to initiate and be retained in weight loss maintenance trials.

Abstract
Cyclosporine A(CsA) is an immunosuppressor frequently used in the transplant surgery and in the treatment of autoimmune diseases. The therapeutic benefits of CsA are often limited by it's main side effect-nephrotoxicity. Mechanisms of chronic CsA- induced renal damage include: activation of renin-angiotensin-aldosterone system, upregulation of transforming growth factor beta (TGF-β), oxidative stress. This study was undertaken to investigate the protective effect of the peroxisome-proliferator-activated receptors gamma (PPARs-γ) agonists: rosiglitazone and 15-deoxy-Δ12,14-prostaglandin J2 (PGDJ2), against CsA-induced kidney injury in male Wistar rats. CsA was administered subcutaneously at a dose of 15 mg/kg/day for 28 days. Both PPAR-γ agonists were given for 28 days 0.5 hour before the administration of CsA. Rosiglitazone was administered orally at a dose of 8 mg/kg/day and PGDJ2 was given intraperitoneally at a dose of 30 μg/kg/day. CsA induced renal failure was evidenced by increased serum levels of urea, uric acid and creatinine. Serum concentrations of GSH and GSSG, lipid peroxidation products as well as NAD+/NADH, NADP+/NADPH and ADP/ATP ratios showed, that CsA induced oxidative stress and evoked an imbalanced red-ox state in the kidney. Light and electron microscope studies showed degenerative changes within renal tubules with damage to their mitochondria, interstitial fibrosis and arteriolopathy. Immunohistochemical expression of profibrotic TGF-β was assessed. The biochemical and morphological changes induced by CsA were limited by administration of both rosiglitazone and PGDJ2. Ultrastructural examination of renal tubular epithelial cells showed marked improvement within mitochondria. Our results indicate that both PPAR-γ agonists used in the experiment may play an important role in protecting against CsA-induced damage in the kidney.

Abstract
CONTEXT Morbid obesity (body mass index (BMI) > or =40 kg/m2) is associated with substantially increased morbidity and mortality from chronic health conditions and with poorer health-related quality of life; however, less is known about the impact of morbid obesity on healthcare expenditures. OBJECTIVE To examine the impact of morbid obesity on healthcare expenditures using a nationally representative sample of US adults. DESIGN, SETTING, AND PARTICIPANTS We performed a cross-sectional analysis of 16 262 adults from the 2000 Medical Expenditure Panel Survey, a nationally representative survey of the noninstitutionalized civilian population of the United States. Per capita healthcare expenditures were calculated for National Institutes of Health BMI categories, based on self-reported height and weight, using a two-part, multivariable model adjusted for age, gender, race, income, education level, type of health insurance, marital status, and smoking status. MAIN OUTCOME MEASURES Odds of incurring any healthcare expenditure and per capita healthcare expenditures associated with morbid obesity in 2000. RESULTS When compared with normal-weight adults, the odds of incurring any healthcare expenditure in 2000 were two-fold greater among adults with morbid obesity. Per capita healthcare expenditures for morbidly obese adults were 81% (95% confidence interval (CI): 48-121%) greater than normal-weight adults, 65% (95% CI: 37-110%) greater than overweight adults, and 47% (95% CI: 11-96%) greater than adults with class I obesity. Excess costs among morbidly obese adults resulted from greater expenditures for office-based visits, outpatient hospital care, in-patient care, and prescription drugs. Aggregate US healthcare expenditures associated with excess body weight among morbidly obese US adults exceeded $11 billion in 2000. CONCLUSIONS The economic burden of morbid obesity among US adults is substantial. Further research is needed to identify interventions to reduce the incidence and prevalence of morbid obesity and improve the health and economic outcomes of morbidly obese adults.

Abstract
This paper analyzes the efficient allocation of consumers to health plans. Specifically, we address the question of why employers that offer multiple health plans often make larger contributions to the premiums of the high-cost plans. Our perspective is that the subsidy for high-cost plans represents a form of demand-side risk adjustment that improves efficiency. Without such subsidies (and in the absence of formal risk adjustment), too few employees would choose the high-cost plans preferred by high-risk workers. We test the theory by estimating a model of the employer premium subsidy, using data from a survey of large public employers in 1994. Our empirical analysis shows that employers are more likely to subsidize high-cost plans when the benefits of risk adjustment are greater. The findings suggest that the premium subsidy can accomplish some of the benefits of formal risk adjustment.

Abstract
The purpose of the study was to assess the safety of the dobutamine stress echocardiography (DASE) in patients with aortic stenosis (AS). 161 patients (mean age 59 +/- 13 years) with AS were prospectively studied with DASE. There were 58 female and 103 male. Dobutamine was given in stepwise increasing doses from 5 to 40 ug/kg/min. Mean maximal dose achieved was 31.4 ug/kg/min. The test was positive in 40 (24.8%) patients. Significant coronary artery disease was present in 60 (37.3%) patients. DASE resulted in significant increase in transvalvular mean gradient from 29.3 +/- 12.5 mmHg at rest to 46.3 +/- 19.3 mmHg at peak dose. There was no significant increase in valve area. There were no death, myocardial infarction or episodes of sustained ventricular tachycardia as a result of DASE. The test was terminated when following conditions were revealed: target heart rate (39.1%), left ventricular asynergy (25.5%), maximal established dose achieved (8.1%), side effects (27.3%). The most common side effects with the need of test cessation were arrhythmias (9.9%) and hypotension (9.9%). The most side effects were usually well tolerated without need of medical treatment. We conclude that DASE may be safely performed in patients with AS. Side effects are more common than in patients with coronary disease, but are usually well tolerated without need of medical treatment.

Abstract
OBJECTIVE To compare adjusted mortality rates of TEFRA-risk HMO enrollees and disenrollees with rates of beneficiaries enrolled in the Medicare fee-for-service sector (FFS), and to compare the time until death for decedents in these three groups. DATA SOURCE Data are from the 124 counties with the largest TEFRA-risk HMO enrollment using 1993-1994 Medicare Denominator files for beneficiaries enrolled in the FFS and TEFRA-risk HMO sectors. STUDY DESIGN A retrospective study that tracks the mortality rates and time until death of a random sample of 1,240,120 Medicare beneficiaries in the FFS sector and 1,526,502 enrollees in HMOs between April 1, 1993 and April 1, 1994. A total of 58,201 beneficiaries switched from an HMO to the FFS sector and were analyzed separately. PRINCIPAL FINDINGS HMO enrollees have lower relative odds of mortality than a comparable group of FFS beneficiaries. Conversely, HMO disenrollees have higher relative odds of mortality than comparable FFS beneficiaries. Among decedents in the three groups, HMO enrollees lived longer than FFS beneficiaries, who in turn lived longer than HMO disenrollees. CONCLUSIONS Medicare TEFRA-risk HMO enrollees appear to be, on average, healthier than beneficiaries enrolled in the FFS sector, who appear to be in turn healthier than HMO disenrollees. These health status differences persist, even after controlling for beneficiary demographics and county-level variables that might confound the relationship between mortality and the insurance sector.

Abstract
BACKGROUND Since the program's inception, there has been great interest in determining whether beneficiaries who enter and subsequently leave Medicare health maintenance organizations (HMOs) are more or less costly than those remaining in fee-for-service (FFS) Medicare. OBJECTIVES To examine whether relatively high-cost beneficiaries disenroll from Medicare HMOs (disenrollment bias) and whether disenrollment bias varies by Medicare HMO market characteristics. In addition, we compare rates of surgical procedures and hospitalizations for ambulatory care-sensitive conditions for disenrollees and continuing FFS beneficiaries. DESIGN Cross-sectional analysis of 1994 Medicare data. PARTICIPANTS AND METHODS Medicare beneficiaries were first sampled from the 124 counties with at least 1000 Medicare HMO enrollees. From this pool, HMO disenrollees and a sample of continuing FFS beneficiaries were drawn. The FFS beneficiaries were assigned dates of "pseudodisenrollment." Expenditures and inpatient service use were compared for 6 months after disenrollment or pseudodisenrollment. RESULTS The HMO disenrollees were no more likely than the continuing FFS beneficiaries to have positive total expenditures (Part A plus Part B) or Part B expenditures in the first 6 months after disenrollment. However, disenrollees were more likely to have Part A expenditures. Among beneficiaries with spending, disenrollees had higher total and Part B expenditures than continuing FFS beneficiaries. Moreover, the disparity in total and Part B spending between disenrollees and continuing FFS beneficiaries increased with HMO market penetration. Although Part A spending was higher for disenrollees with spending, it was not sensitive to changes in market share. The HMO disenrollees received more surgical procedures and were hospitalized for more of the ambulatory care-sensitive conditions than the FFS beneficiaries. CONCLUSIONS On several measures, Medicare HMOs experienced favorable disenrollment relative to continuing FFS beneficiaries as recently as 1994, which increased as HMO market share increased.

Abstract
Using 1993 and 1994 data, the authors examine whether beneficiaries who enroll in a Medicare health maintenance organization (HMO), including those enrolling for only a short period of time, have lower expenditures than continuous fee-for-service (FFS) beneficiaries the year prior to enrollment. We also test whether biased selection varies by the level of HMO market penetration and the rate of market-share growth. We find favorable selection associated with enrollment into Medicare HMOs, which declines as market share increases but does not disappear. Among short-term enrollees, we find unfavorable selection, however, selection bias was not sensitive to market characteristics.

Abstract
State governments play many roles in local health insurance markets. This paper focuses on the role of states as employers. As managed care and health care costs continue to grow, state governments engage in a variety of health insurance purchasing practices that influence the structure of health benefits offered to state employees. Descriptive analysis shows that many states have adopted managed competition to some degree, as well as traditional cost-reducing measures such as utilization review and self insurance. The experience of state governments can provide a benchmark for other public and private employers.

Abstract
OBJECTIVES The authors examine the relationship between three dimensions of patient satisfaction (quality of care, hospital care, and physician time) and two ways of looking at outcomes: absolute (status at 6 months after surgery) and relative (difference between baseline and follow-up status). METHODS A total of 2,116 patients undergoing cholecystectomy were interviewed before surgery and again at 6 months. The baseline interview addressed health status (general functioning and specific symptoms) and risk factors. The follow-up interview included health status and a series of satisfaction questions. Outcomes included both overall health status and specific symptoms. Potential confounding factors, in addition to baseline status, such as demographics, casemix, and procedure type, were accounted for in the analysis. RESULTS Each of the outcomes was related significantly to each of the satisfaction scales; however, the relative outcomes were related more strongly to satisfaction than were the absolute versions. Although the regression coefficients were highly significant, none of the outcomes measures accounted for more than 8% of the explained variance in the several satisfaction scores. CONCLUSIONS Although outcomes and satisfaction are related, more goes into satisfaction than just outcomes. When determining their satisfaction with the care they have received, patients are more likely to focus on their present state of health than to consider the extent of improvement they have enjoyed.

Abstract
Pediatric patients with complex congenital cardiac defects present unique challenges in hemodynamic monitoring to the critical care nurse. An understanding of the hemodynamic alterations caused by both the underlying lesions and the surgical repairs is necessary to establish acceptable parameters in caring for these patients. In these complex patients, understanding expected deviations from normal ranges and integrating this information with clinical presentations is critical for individualizing effective interventions. An overview of hemodynamic monitoring and two advanced case studies are presented.
