Does Quality of Care Matter? A Study of Adherence to National Comprehensive Cancer Network Guidelines for Patients with Locally Advanced Esophageal Cancer

The aim of this study was to assess whether adherence to National Comprehensive Cancer Network (NCCN) guidelines leads to differences in survival in patients diagnosed with locally advanced esophageal cancer. This is a retrospective cohort study of patients with stage II and III esophageal cancer included in the Cancer Registry at the Sidney Kimmel Comprehensive Cancer Center at the Johns Hopkins Hospital from 2008 to 2013. Seven quality indicators were identified using the 2014 NCCN guidelines, and individual and overall quality measure scores were calculated and used to define low and high quality of care groups. One hundred forty-one patients met inclusion criteria, and 88 patients (62.4 %) were identified as receiving high-quality care. Adherence to guidelines ranged from 63.1 to 100.0 %, with an overall compliance of 81.3 %. Risk factors for receiving low quality of care included advanced age, non-white race, lower education level, and unspecified primary site of tumor. A significantly better overall survival was observed in patients who received high-quality care (HR, 0.58; 95 %, 0.37–0.90, p = 0.015). Delivery of high-quality care is associated with improved survival in these patients. Efforts should be directed at minimizing disparities in treatment in regards to race and educational levels.
Computerized arm training improves the motor control of the severely affected arm after stroke: a single-blinded randomized trial in two centers.

To compare a computerized arm trainer (AT), allowing repetitive practice of passive and active bilateral forearm and wrist movement cycle, and electromyography-initiated electrical stimulation (ES) of the paretic wrist extensor in severely affected subacute stroke patients.



A total of 44 patients, 4 to 8 weeks after stroke causing severe arm paresis (Fugl-Meyer Motor Score [FM, 0 to 66] <18), were randomly assigned to either AT or ES. All patients practiced 20 minutes every workday for 6 weeks. AT patients performed 800 repetitions per session with the robot and ES patients performed 60 to 80 wrist extensions per session. The primary outcome measure was the blindly assessed FM (0 to 66), and the secondary measures were the upper limb muscle power (Medical Research Council [MRC] sum, 0 to 45) and muscle tone (Ashworth score sum, 0 to 25), assessed at the beginning and end of treatment and at 3-month follow-up.



The AT group had a higher Barthel Index score at baseline, but the groups were otherwise homogenous. As expected, FM and MRC sum scores improved overtime in both groups but significantly more in the robot AT group. The initial Barthel Index score had no influence. In the robot AT group, FM score was 15 points higher at study end and 13 points higher at 3-month follow-up than the control ES group. MRC sum score was 15 points higher at study end and at 3-month follow-up compared with the control ES group. Muscle tone remained unchanged, and no side effects occurred.



The computerized active arm training produced a superior improvement in upper limb motor control and power compared with ES in severely affected stroke patients. This is probably attributable to the greater number of repetitions and the bilateral approach.
Ventilation with lower tidal volumes as compared with traditional tidal volumes for acute lung injury and the acute respiratory distress syndrome.

Traditional approaches to mechanical ventilation use tidal volumes of 10 to 15 ml per kilogram of body weight and may cause stretch-induced lung injury in patients with acute lung injury and the acute respiratory distress syndrome. We therefore conducted a trial to determine whether ventilation with lower tidal volumes would improve the clinical outcomes in these patients.



Patients with acute lung injury and the acute respiratory distress syndrome were enrolled in a multicenter, randomized trial. The trial compared traditional ventilation treatment, which involved an initial tidal volume of 12 ml per kilogram of predicted body weight and an airway pressure measured after a 0.5-second pause at the end of inspiration (plateau pressure) of 50 cm of water or less, with ventilation with a lower tidal volume, which involved an initial tidal volume of 6 ml per kilogram of predicted body weight and a plateau pressure of 30 cm of water or less. The primary outcomes were death before a patient was discharged home and was breathing without assistance and the number of days without ventilator use from day 1 to day 28.



The trial was stopped after the enrollment of 861 patients because mortality was lower in the group treated with lower tidal volumes than in the group treated with traditional tidal volumes (31.0 percent vs. 39.8 percent, P=0.007), and the number of days without ventilator use during the first 28 days after randomization was greater in this group (mean [+/-SD], 12+/-11 vs. 10+/-11; P=0.007). The mean tidal volumes on days 1 to 3 were 6.2+/-0.8 and 11.8+/-0.8 ml per kilogram of predicted body weight (P<0.001), respectively, and the mean plateau pressures were 25+/-6 and 33+/-8 cm of water (P<0.001), respectively.



In patients with acute lung injury and the acute respiratory distress syndrome, mechanical ventilation with a lower tidal volume than is traditionally used results in decreased mortality and increases the number of days without ventilator use.
Changes in Renal Function in Patients With Atrial Fibrillation: An Analysis From the RE-LY Trial.

Vitamin K-dependent factors protect against vascular and renovascular calcification, and vitamin K antagonists may be associated with a decreased glomerular filtration rate (GFR).



This study analyzed changes in GFR during long-term treatment with warfarin or dabigatran etexilate (DE) in patients enrolled in the RE-LY (Randomized Evaluation of Long Term Anticoagulation Therapy) trial.



Of the 18,113 patients in the RE-LY study randomized to receive DE (110 mg or 150 mg twice daily) or warfarin, 16,490 patients with atrial fibrillation had creatinine values measured at baseline and at least 1 follow-up visit. Changes in GFR for up to 30 months were evaluated.



GFR declined in all treatment groups. After an average of 30 months, the mean ± SE decline in GFR was significantly greater with warfarin (-3.68 ± 0.24 ml/min) compared with DE 110 mg (-2.57 ± 0.24 ml/min; p = 0.0009 vs. warfarin) and DE 150 mg (-2.46 ± 0.23 ml/min; p = 0.0002 vs. warfarin). A decrease in GFR >25% was less likely with DE 110 mg (hazard ratio: 0.81 [95% confidence interval: 0.69 to 0.96]; p = 0.017) or DE 150 mg (hazard ratio: 0.79 [95% confidence interval: 0.68 to 0.93]; p = 0.0056) than with warfarin in the observation period >18 months. Patients with poor international normalized ratio control (i.e., time in therapeutic range <65%) exhibited a faster decline in GFR. A more pronounced decline in GFR was associated with previous warfarin use and with the presence of diabetes.



Patients with atrial fibrillation receiving oral anticoagulation exhibited a decline in renal function that was greater in those taking warfarin versus DE, and it was amplified by diabetes and previous vitamin K antagonist use.

Comparison of optometry vs digital photography screening for diabetic retinopathy in a single district

AbstractPurpose To compare (a) the clinical effectiveness and (b) cost effectiveness of the two models in screening for diabetic retinopathy.Methods (a) Retrospective analysis of referral diagnoses of each screening model in their first respective years of operation and an audit of screen positive patients and a sample of screen negatives referred to the hospital eye service from both screening programmes. (b) Cost effectiveness study.Participants (1) A total of 1643 patients screened in the community and in digital photography clinics; (2) 109 consecutive patients referred to the Diabetic Eye Clinic through the two existing models of diabetic retinopathy screening; (3) 55 screen negative patients from the optometry model; (4) 68 screen negative patients audited from the digital photography model.The compliance rate was 45% for optometry (O) vs50% for the digital imaging system (I). Background retinopathy was recorded at screening in 22% (O) vs17% (I) (P=0.03) and maculopathy in 3.8% (O) vs1.7% (I) (P=0.02). Hospital referral rates were 3.8% (O) vs4.2% (I) Sensitivity (75% for optometry, 80% for digital photography) and specificity (98% for optometry and digital photography) were similar in both models. The cost of screening each patient was £23.99 (O) vs£29.29 (I). The cost effectiveness was £832 (O) vs£853(I) in the first year.The imaging system was not always able to detect early retinopathy and maculopathy; it was equally specific in identifying sight-threatening disease. Cost effectiveness was poor in both models, in their first operational year largely as a result of poor compliance rates in the newly introduced screening programme. Cost effectiveness of the imaging model should further improve with falling costs of imaging systems. Until then, it is essential to continue any existing well-coordinated optometry model.
Anti-infective periodontal therapy promoting improvement in systemic markers of HIV infection.

Research supports the theory that the chronic infectious response occurring in periodontal disease may have a role as a risk modifier of systemic diseases. This study assessed the impact of HIV-associated chronic periodontitis treatment on systemic HIV-related markers (CD4 T lymphocytes cell counts and HIV viral load). Fifteen HIV patients presenting chronic periodontitis [at least eight sites presenting a probing depth (PD) >4 mm and bleeding] were included in this study. Patients received full mouth periodontal treatment with an ultrasonic device and supragingival plaque control. Medical (CD4 cell counts and HIV load) as well as periodontal clinical parameters [probing pocket depth (PPD), clinical attachment level (CAL)] were assessed at baseline and 3 and 6 months after treatment. Tukey and Pearson's correlation tests were used for statistical analysis (α=5%). The results showed that PPD reduction and CAL gain were statistically significant at 3 and 6 months after periodontal therapy (p<0.05). At 6 months, CAL gain was 0.6±0.5 mm and PPD reduction was 0.7±0.5 mm. At the same time, a statistically significant increase in CD4 cell counts could be seen after the third month (p<0.05) and sixth month (p<0.05). Moreover, at 6 months, the relationship between the improvement in clinical parameters, i.e., PPD reduction, and the number of TCD4 lymphocytes could be highlighted. This was shown as the greater the PPD reduction, the greater the increase in TCD4 cells (r=0.68, p=0.02). These data suggest that periodontitis treatment could be associated with an improvement in medical conditions in HIV subjects.
ST-segment elevation myocardial infarction treated by radial or femoral approach in a multicenter randomized clinical trial: the STEMI-RADIAL trial.

This study sought to compare radial and femoral approaches in patients presenting with ST-segment elevation myocardial infarction (STEMI) and undergoing primary percutaneous coronary intervention (PCI) by high-volume operators experienced in both access sites.



The exact clinical benefit of the radial compared to the femoral approach remains controversial.



STEMI-RADIAL (ST Elevation Myocardial Infarction treated by RADIAL or femoral approach) was a randomized, multicenter trial. A total of 707 patients referred for STEMI <12 h of symptom onset were randomized in 4 high-volume radial centers. The primary endpoint was the cumulative incidence of major bleeding and vascular access site complications at 30 days. The rate of net adverse clinical events (NACE) was defined as a composite of death, myocardial infarction, stroke, and major bleeding/vascular complications. Access site crossover, contrast volume, duration of intensive care stay, and death at 6 months were secondary endpoints.



The primary endpoint occurred in 1.4% of the radial group (n = 348) and 7.2% of the femoral group (n = 359; p = 0.0001). The NACE rate was 4.6% versus 11.0% (p = 0.0028), respectively. Crossover from radial to femoral approach was 3.7%. Intensive care stay (2.5 ± 1.7 days vs. 3.0 ± 2.9 days, p = 0.0038) as well as contrast utilization (170 ± 71 ml vs. 182 ± 60 ml, p = 0.01) were significantly reduced in the radial group. Mortality in the radial and femoral groups was 2.3% versus 3.1% (p = 0.64) at 30 days and 2.3% versus 3.6% (p = 0.31) at 6 months, respectively.



In patients with STEMI undergoing primary PCI by operators experienced in both access sites, the radial approach was associated with significantly lower incidence of major bleeding and access site complications and superior net clinical benefit. These findings support the use of the radial approach in primary PCI as first choice after proper training.
Treatment with the antibiotic roxithromycin in patients with acute non-Q-wave coronary syndromes. The final report of the ROXIS Study.

Mounting evidence suggests infection, specifically Chlamydia pneumoniae, plays a role in atherosclerosis. We tested whether antibiotic treatment with the macrolide roxithromycin improves clinical outcome in patients with acute non-Q-wave coronary syndromes. Preliminary reports revealed a reduction in events in the roxithromycin group at 30 days. We now report the long-term follow-up results.



Sixty-four per cent of the initial 202 patients with unstable angina who were randomly assigned to receive either roxithromycin or placebo for 30 days completed the active treatment period. At day 30, the primary triple and double end-point rates were 9% and 4% in the placebo group compared to 2% and 0% in the roxithromycin group (unadjusted P = 0.032 and 0.058, respectively). The secondary triple and double end-point rates were again higher in the placebo group at day 90 (12.5% and 6.25% vs 4.37% and 0%, unadjusted P = 0.065 and 0.029, respectively), and at day 180 (14.6% and 7.29% vs 8.69% and 2.17%, unadjusted P = 0.259 and 0.17, respectively). Anti-C, pneumoniae IgG titres were unchanged in both groups while C-reactive protein levels decreased in both strategies, with a more significant decrease in the roxithromycin arm (P = 0.03). Elevated C-reactive protein levels predicted the need for revascularization.



In this pilot trial, roxithromycin appears to extend the clinical benefit of preventing death and re-infarction for at least 6 months after initial treatment.
Posttraumatic stress disorder in victims of the March 11 attacks in Madrid admitted to a hospital emergency room: 6-month follow-up.

To determine the change in prevalence of posttraumatic stress disorder (PTSD) symptoms in victims of the March 11 attacks and their relatives, 1 and 6 months after the attacks.



Evaluation of PTSD symptoms using the Davidson Trauma Scale (DTS) and General Health Questionnaire (GHQ) in a sample of 56 patients admitted to an emergency room of a general hospital, and assessment of PTSD symptoms in relatives of the patients.



At Month 1, 41.1% of patients (31.3% of males and 54.2% of females) presented with PTSD. At Month 6, this figure was 40.9% (30.4% of males and 52.4% of females). There was a significant improvement in perception of health among females between Month 1 and Month 6. Relatives presented similar DTS scores at baseline and at 6 months.



We verified that rates of PTSD did not vary substantively between the two evaluations. PTSD symptoms positively correlated with psychological health involvement. This correlation points out that both PTSD symptoms and subjective general health involvement are part of the psychological response to trauma.



The prevalence of PTSD symptoms was high and remained stable between Month 1 and Month 6, while subjective perception of health improved significantly.
The lipid management nutrition outcomes project: perspectives from a national experience in protocol implementation and nutrition outcomes tracking.

The Lipid Management Nutrition Outcomes Project was a multicenter prospective noncontrolled observational study in which a network of 51 registered dietitians (RDs) from practice settings across the United States implemented the 1998 Medical Nutrition Therapy Hyperlipidemia Protocol and collected outcomes. Difficulty recruiting RDs and enrolling patients revealed a gap between practice guidelines and clinical practice. Many RDs did not have laboratory values or follow-up visits required by the protocol. RDs able to follow protocol recommendations had the expected positive results. Within a 6-month period, 377 new patients presenting for lipid management met inclusion/exclusion criteria. Some follow-up data were available on 280 (74.3%) patients. There were follow-up lipid data prior to lipid-lowering medication changes for 219 patients. Reported mean dietary fat intake was reduced to <30% (P<0.0001). The population lost weight and increased exercise frequency (P<0.001, P<0.001). In the 175 patients with initial triglycerides <400 mg/dL (4.52 mmol/L), 44.6% had either a 15% drop in low-density lipoprotein cholesterol or reached low-density lipoprotein cholesterol goal. Lipid response occurred in 34.7+/-16.5 weeks with 3.0+/-1.4 RD visits. The Lipid Management Nutrition Outcomes Project highlights frustrations and values of outcomes monitoring in actual practice and identifies areas for practice advancement.
Validation of the Safe at Home Screening with Adults Who Have Acquired Brain Injury.

The Safe at Home Screening (SAH) is an occupational therapy assessment tool designed to quickly assess home safety awareness and skills through the use of mock hazardous situations in a kitchen setting. The SAH has been standardized on community-dwelling adults. This research project involves psychometric analyses using the SAH on a sample of adults with acquired brain injuries (ABI; N = 31), and compares their SAH outcome scores with those of the Kohlman Evaluation of Living Skills (KELS). The scores on the two tests were found to be moderately correlated. An aspect of content validity was explored by asking the clients' occupational therapists to make predictions about their clients' functioning in the realm of home safety. Correlations between the expert opinions of potential client scores and actual SAH test scores were moderate.
Randomized trial of a GPIIb/IIIa platelet receptor blocker in refractory unstable angina. European Cooperative Study Group.

Patients with unstable angina despite intensive medical therapy, ie, refractory angina, are at high risk for developing thrombotic complications: myocardial infarction or coronary occlusion during percutaneous transluminal coronary angioplasty (PTCA). Chimeric 7E3 (c7E3) Fab is an antibody fragment that blocks the platelet glycoprotein (GP) IIb/IIIa receptor and potently inhibits platelet aggregation.



To evaluate whether potent platelet inhibition could reduce these complications, 60 patients with dynamic ST-T changes and recurrent pain despite intensive medical therapy were randomized to c7E3 Fab or placebo. After initial angiography had demonstrated a culprit lesion suitable for PTCA, placebo or c7E3 Fab was administered as 0.25 mg/kg bolus injection followed by 10 micrograms/min for 18 to 24 hours until 1 hour after completion of second angiography and PTCA. During study drug infusion, ischemia occurred in 9 c7E3 Fab and 16 placebo patients (P = .06). During hospital stay, 12 major events occurred in 7 placebo patients (23%), including 1 death, 4 infarcts, and 7 urgent interventions. In the c7E3 Fab group, only 1 event (an infarct) occurred (3%, P = .03). Angiography showed improved TIMI flow in 4 placebo and 6 c7E3 Fab patients and worsening of flow in 3 placebo patients but in none of the c7E3 Fab patients. Quantitative analysis showed significant improvement of the lesion in the patients treated with c7E3 Fab, which was not observed in the placebo group, although the difference between the two treatment groups was not significant. Measurement of platelet function and bleeding time demonstrated > 90% blockade of GPIIb/IIIa receptors, > 90% reduction of ex vivo platelet aggregation to ADP, and a significantly prolonged bleeding time during c7E3 Fab infusion, without excess bleeding.



Combined therapy with c7E3 Fab, heparin, and aspirin appears safe. These pilot study results support the concept that effective blockade of the platelet GPIIb/IIIa receptors can reduce myocardial infarction and facilitate PTCA in patients with refractory unstable angina.
Are obesity and body fat distribution associated with low back pain in women? A population-based study of 1128 Spanish twins

To investigate the relationship between different measures of obesity and chronic low back pain (LBP) using a within-pair twin case–control design that adjusts for genetics and early shared environment. A cross-sectional association between lifetime prevalence of chronic LBP and different measures of obesity (body mass index-BMI; percent body fat; waist circumference; waist–hip ratio) was investigated in 1128 female twins in three stages: (i) total sample analysis; (ii) within-pair case–control analysis for monozygotic (MZ) and dizygotic (DZ) twins together; (iii) within-pair case–control analysis separated by DZ and MZ. Odds ratios (OR) and 95 % confidence intervals (CI) were calculated. BMI (OR 1.12; 95 % CI 1.02–1.26) and percent body fat (OR 1.15; 95 % CI 1.01–1.32) were weakly associated with lifetime prevalence of chronic LBP in the total sample analysis but were absent when shared environment and genetic factors were adjusted for using the within-pair case–control analysis. Greater waist–hip ratios were associated with smaller prevalence estimates of chronic LBP in the within-pair case–control analysis with both MZ and DZ twins (OR 0.67; 95 % CI 0.47–0.94). However, this association did not remain after the full adjustment for genetic factors in the MZ within-pair case–control analysis. BMI, percent of fat mass and greater depositions of fat and mass around the hips are associated with increases in chronic LBP prevalence in women but these associations are small and appear to be confounded by the effects of genetics and early shared environment. Therefore, our results do not support a causal direct relationship between obesity and chronic LBP.
