Post-Traumatic Stress Outcomes in Non-Hodgkin's Lymphoma Survivors

A large body of evidence suggests that being diagnosed with and treated for cancer adversely affects functioning and quality of life, yet less is known about longer term outcomes. Therefore, this study aims to estimate the prevalence of post-traumatic stress disorder (PTSD) symptoms in survivors of adult non-Hodgkin’s lymphoma (NHL) who are at least 2 years postdiagnosis and identify the risk factors associated with PTSD symptoms, with a focus on those that are amenable for screening and modifiable

The Lifelong Mortality Risks of World War II Experiences

This longitudinal study of American veterans investigated the mortality risks of five World War II military experiences (i.e., combat exposure) and their variation among veterans in the post-war years

Numerical simulation of blood flow and pressure drop in the pulmonary arterial and venous circulation

A novel multiscale mathematical and computational model of the pulmonary circulation is presented and used to analyse both arterial and venous pressure and flow. This work is a major advance over previous studies by Olufsen et al. (Ann Biomed Eng 28:1281–1299, 2012) which only considered the arterial circulation. For the first three generations of vessels within the pulmonary circulation, geometry is specified from patient-specific measurements obtained using magnetic resonance imaging (MRI). Blood flow and pressure in the larger arteries and veins are predicted using a nonlinear, cross-sectional-area-averaged system of equations for a Newtonian fluid in an elastic tube. Inflow into the main pulmonary artery is obtained from MRI measurements, while pressure entering the left atrium from the main pulmonary vein is kept constant at the normal mean value of 2 mmHg. Each terminal vessel in the network of ‘large’ arteries is connected to its corresponding terminal vein via a network of vessels representing the vascular bed of smaller arteries and veins. We develop and implement an algorithm to calculate the admittance of each vascular bed, using bifurcating structured trees and recursion. The structured-tree models take into account the geometry and material properties of the ‘smaller’ arteries and veins of radii ≥ 50 μ m. We study the effects on flow and pressure associated with three classes of pulmonary hypertension expressed via stiffening of larger and smaller vessels, and vascular rarefaction. The results of simulating these pathological conditions are in agreement with clinical observations, showing that the model has potential for assisting with diagnosis and treatment for circulatory diseases within the lung

Prevalence of distressing symptoms in hospitalised patients on medical wards: A cross-sectional study

<p>Abstract</p> <p>Background</p> <p>Many patients with advanced, serious, non-malignant disease belong to the population generally seen on medical wards. However, little research has been carried out on palliative care needs in this group. The aims of this study were to estimate the prevalence of distressing symptoms in patients hospitalised in a Department of Internal Medicine, estimate how many of these patients might be regarded as palliative, and describe their main symptoms.</p> <p>Methods</p> <p>Cross-sectional (point prevalence) study. All patients hospitalised in the Departments of Internal Medicine, Pulmonary Medicine, and Cardiology were asked to do a symptom assessment by use of the Edmonton Symptom Assessment System (ESAS). Patients were defined as "palliative" if they had an advanced, serious, chronic disease with limited life expectancy and symptom relief as the main goal of treatment.</p> <p>Results</p> <p>222 patients were registered in all. ESAS was completed for 160 patients. 79 (35.6%) were defined as palliative and 43 of them completed ESAS. The patients in the palliative group were older than the rest, and reported more dyspnea (70%) and a greater lack of wellbeing (70%). Other symptoms reported by this group were dry mouth (58%), fatigue (56%), depression (41%), anxiety (37%), pain at rest (30%), and pain on movement (42%).</p> <p>Conclusion</p> <p>More than one third of the patients in a Department of Internal Medicine were defined as palliative, and the majority of the patients in this palliative group reported severe symptoms. There is a need for skills in symptom control on medical wards.</p

Circulating 25-Hydroxyvitamin D and Risk of Pancreatic Cancer: Cohort Consortium Vitamin D Pooling Project of Rarer Cancers

Results from epidemiologic studies examining pancreatic cancer risk and vitamin D intake or 25-hydroxyvitamin D (25(OH)D) concentrations (the best indicator of vitamin D derived from diet and sun) have been inconsistent. Therefore, the authors conducted a pooled nested case-control study of participants from 8 cohorts within the Cohort Consortium Vitamin D Pooling Project of Rarer Cancers (VDPP) (1974–2006) to evaluate whether prediagnostic circulating 25(OH)D concentrations were associated with the development of pancreatic cancer. In total, 952 incident pancreatic adenocarcinoma cases occurred among participants (median follow-up, 6.5 years). Controls (n = 1,333) were matched to each case by cohort, age, sex, race/ethnicity, date of blood draw, and follow-up time. Conditional logistic regression analysis was used to calculate smoking-, body mass index-, and diabetes-adjusted odds ratios and 95% confidence intervals for pancreatic cancer. Clinically relevant 25(OH)D cutpoints were compared with a referent category of 50–<75 nmol/L. No significant associations were observed for participants with lower 25(OH)D status. However, a high 25(OH)D concentration (≥100 nmol/L) was associated with a statistically significant 2-fold increase in pancreatic cancer risk overall (odds ratio = 2.12, 95% confidence interval: 1.23, 3.64). Given this result, recommendations to increase vitamin D concentrations in healthy persons for the prevention of cancer should be carefully considered

The relationship between older cancer survivors’ reports of depression, anxiety and pain to health providers’ findings and mortality

8597 Background: Older cancer survivors may experience psychological distress due to their cancer experience and aging health. This study aimed to compare primary care and specialty providers’ inquiries of pain, depression and anxiety to older cancer survivors’ questionnaire responses. Methods: 153 patients seen in oncology clinics at the Veterans Affairs Medical Center (Durham, NC) from November 1999 until April 2000 completed the Hospital Anxiety and Depression Scale and a pain thermometer questionnaire. Blinded chart review examined health provider inquiries of pain, anxiety and depression. Cox proportional hazards survival analyses were performed on subjective pain, anxiety and depression with comorbidities and Karnofsky performance status (KPS) added in controlled models. Results: Patients were on average aged 68, had 5.4 comorbidities, 87.4% KPS, and were 3.1 years from a cancer diagnosis. Health providers missed 17 of 94 patients with significant levels of self-reported pain (sensitivity 0.82). Although 28 (20.6%) and 33 (25.8%) patients screened positively for depression and anxiety respectively, providers asked 7 patients about anxiety (sensitivity 0.15) and 16 patients about depression (sensitivity 0.25). The overall three year mortality was 37.9%. Pain was not associated with mortality. Patients screening for depression [HR 2.03 (95% CI: 1.03, 4.01)] and anxiety [HR 2.02 (95% CI: 1.01, 4.04)] had lower 3 year survival. KPS and comorbidities diminished these effects. Conclusions: In older cancer survivors, anxiety and depression may have an association with mortality. To improve detection, oncology and primary care providers should routinely inquire about mood and aim to intervene with pharmacologic or supportive treatments.
