The Impact of a Home-Delivered Meal Program on Nutritional Risk,Dietary Intake,Food Security,Loneliness, and Social Well-Being

Maintaining independence and continuing to live at home is one solution to manage the rising health care costs of aging populations in the United States; furthermore, seniors are at risk of malnutrition and food insecurity. Home-delivered meal programs are a tool to address food, nutrition, and well-being concerns of this population. Few studies have identified outcomes from these programs; this pilot study reviews the nutritional status, dietary intake, well-being, loneliness, and food security levels of seniors participating in a Meals on Wheels delivery service. Clients, new to the meal program, participated in pre- and postphone interviews, and 51 seniors completed the study. The survey was composed of five scales or questionnaires, and statistical analyses were conducted using SPSS. Improvements across all five measures were statistically significant after participating two months in the home-delivered meal program. Implications for further research, practice, and the Older Americans Act are discussed.     

Stop-flow in mediastinum and thorax for resistant lymphoma

BACKGROUND/AIMS: Management of patients with heavily pretreated malignant lymphoma failing frontline treatment and salvage high-dose chemotherapy and autologous peripheral stem cell rescue, is problematic. A pilot study was conducted to evaluate isolated thoracic perfusion of drugs by means of stopflow technique. METHODOLOGY: Six patients were enrolled in the study; diagnoses included 4 advanced Hodgkin's disease, 1 primary mediastinal B-cell lymphoma, and 1 anaplastic large cell lymphoma. Patients were aged 18-37 years; 4 presented with bulky mediastinum. They had never achieved a complete response since all had progressed from front-line treatment, and 3 had even failed salvage high-dose chemotherapy with autologous peripheral stem cell rescue. Cisplatin (100 mg/m2) and melphalan (35 mg/m2) were used. Carmustine (100 mg/m2) were added to these 2 drugs and cytarabine (2000 mg/m2) in patients not previously treated by carmustine, etoposide, cytarabine, and melphalan. Epidoxorubicin (70 mg/m2) was added in patients who previously received a suboptimal dosage of antracycline. Drugs were delivered monthly via aortic perfusion performed by means of Aigner's stop-flow technique. RESULTS: Overall 13 cycles of perfusional chemotherapy were administered with a median number of 2 cycles. During the procedures there were no technical, hemodynamic, or vascular complications, and no deaths occurred during surgery. After 1 month, 6 (100%) objective responses after isolated thoracic perfusion were recorded, 3 (50%) of which were complete. Tolerance to therapy was excellent. Hematological toxicity was mild and transfusional support was needed only in one course. At the last follow-up, 2 patients are alive (1 complete response and 1 very good partial response, maintained). CONCLUSIONS: This new therapeutical approach seems very active in recurrent/refractory malignant lymphoma and may play an important role in this setting.     

Usefulness of excitable gap and pattern of resetting in atrial flutter for determining reentry circuit location

Clinical and experimental data show that type I atrial flutter is due to a reentry mechanism with an excitable gap. To define the location of the reentry circuit of atrial flutter, width of excitable gap, poststimulation cycle and pattern of reset after premature stimulus were analyzed in 18 patients during atrial flutter at multiple atrial sites (high, lateral, posterior and septal right atrium, and coronary sinus). The pattern of reset was defined as flat or increasing whether the return cycle remained unchanged or prolonged with increasing prematurity. Shorter values of the excitable gap were found at the coronary sinus (33 +/- 8 ms) and high right atrium (30 +/- 10 ms) than at the posterior (43 +/- 9 ms) or septal right atrium (45 +/- 11 ms). Intermediate values (36 +/- 8 ms) were measured at the lateral right atrium. Poststimulation cycle, corrected for atrial flutter cycle length, was shorter in the posterior (6 +/- 7 ms) and septal right atrium (5 +/- 7 ms) than in the coronary sinus (35 +/- 9 ms), and the high (23 +/- 10 ms) and lateral right atrium (15 +/- 9 ms). A flat pattern of resetting occurred more frequently at the septal (18 of 18 patients) and posterior right atrium (15 of 18) than at the lateral (8 of 18) and high right atrium (2 of 17), and was never observed at the coronary sinus. Atrial flutter was successfully terminated by overdrive atrial pacing in 15 of 18 patients, and termination was more easily obtained from the septal and posterior right atrium.(ABSTRACT TRUNCATED AT 250 WORDS)     

Expanding indications for the treatment of pulmonary artery stenosis in children by using cutting balloon angioplasty.

OBJECTIVES: To evaluate the role of cutting balloon angioplasty in children with pulmonary artery stenosis. BACKGROUND: Pulmonary artery stenoses can be either congenital or secondary to postoperative scar formation. Isolated multiple small-vessel pulmonary artery stenoses are very rare. No surgical procedures for their treatment are currently available. METHODS: We report on four patients in whom standard and high-pressure balloon angioplasty had failed. Three of the four (2.5-, 3-, and 3.5-years-old; two girls) had isolated multiple peripheral pulmonary artery stenosis. The fourth patient was an 11-month-old girl (8 kg) with tetralogy of Fallot and hypoplastic pulmonary artery branches treated with the implantation of two stents in the pulmonary arteries. During the follow-up this patient developed severe intrastent restenosis and showed severely hypoplasic distal left pulmonary artery. RESULTS: We treated 11 vessels. The mean vessel diameter increased by 81% (P<0.0001) and RV/LV pressure ratio decreased from 1.15 to 0.75 (P=0.05). Patient treated for intrastent restenosis underwent successful complete tetralogy of Fallot repair. None of the patients suffered procedure-related complications. At a median follow-up of 18 months, results were stable and no late complications had occurred. CONCLUSIONS: Cutting balloon angioplasty is a promising technique for the treatment of highly challenging pathologies such as small vessel pulmonary artery stenoses and intrastent restenosis.     

Pre-Menopausal Breast Fat Density Might Predict MACE During 10 Years of Follow-Up: The BRECARD Study

ObjectivesThis study sought to determine whether the breast gland adipose tissue is associated with different rates of major adverse cardiac events (MACEs) in pre-menopausal women.BackgroundTo our knowledge, no study investigated the impact of breast adipose tissue infiltration on MACEs in pre-menopausal women.MethodsProspective multicenter cohort study conducted on pre-menopausal women >40 years of age without cardiovascular disease and breast cancer at enrollment. The study started in January 2000 and ended in January 2009, and the end of the follow-up for the evaluation of MACEs was in January 2019. Participants underwent mammography to evaluate breast density and were divided into 4 groups according to their breast density. The primary endpoint was the probability of a MACE at 10 years of follow-up in patients staged for different breast deposition/adipose tissue deposition.ResultsThe propensity score matching divided the baseline population of 16,763 pre-menopausal women, leaving 3,272 women according to the category of breast density from A to D. These women were assigned to 4 groups of the study according to baseline breast density. At 10 years of follow-up, we had 160 MACEs in group 1, 62 MACEs in group 2, 27 MACEs in group 3, and 16 MACEs in group 4. MACEs were predicted by the initial diagnosis of lowest breast density (hazard ratio: 3.483; 95% confidence interval: 1.476 to 8.257). Further randomized clinical trials are needed to translate the results of the present study into clinical practice. The loss of ex vivo breast density models to study the cellular/molecular pathways implied in MACE is another study limitation.ConclusionsAmong pre-menopausal women, a higher evidence of adipose tissue at the level of breast gland (lowest breast density, category A) versus higher breast density shows higher rates of MACEs. Therefore, the screening mammography could be proposed in overweight women to stage breast density and to predict MACEs.
