Distress: Characterizing What Causes the Thermometer to Shift in Patients with Newly Diagnosed Breast Cancer Attending a Multidisciplinary Clinic.

BACKGROUND: A diagnosis of breast cancer (BC) can result in multifactorial stress. If not addressed, distress can have a negative impact on outcomes. The experience of patients with newly diagnosed BC has not been sufficiently investigated. This study characterizes distress among new patients in a multidisciplinary care (MDC) clinic. The study aimed to determine the degree of distress at presentation, to characterize the sources, and to evaluate the impact of an MDC visit. METHODS: A retrospective review was performed from January 2015 to November 2017. Charts were accessed for demographics, tumor characteristics, and treatment data. Distress scores (DS) and problems as captured using the National Comprehensive Cancer Network (NCCN) Distress Thermometer were completed before evaluation and in a subgroup after an MDC visit. Predictors of severe distress (DS ≥4) were investigated using multivariable logistic regression. The paired t test was used to determine the impact of an MDC visit. RESULTS: The mean initial DS (n = 474) was 4.98. The top four sources of distress were worry, anxiety, fears, and sadness. Age younger than 65 years was significantly associated with a higher DS at presentation (p < 0.003). Among the patients queried before and after MDC (n = 137), a significant reduction in distress was identified (5.58-2.94; p < 0.0005). CONCLUSIONS: Severe distress was found in 66 % of the patients with a recent diagnosis of BC, with younger age related to higher distress scores at presentation. Emotional stressors were the predominant factors accounting for distress. A same-day MDC visit was associated with a significant reduction in DS. These data indicate the importance and feasibility of proactively screening patients. Our research lends support to the value of multidisciplinary evaluation in this setting.

Inhibition of Integrin VLA-3 and Tetraspanin CD151 Protects Against Neutrophil-Mediated Endothelial Damage.

BACKGROUND: The recruitment of neutrophils to sites of localized injury or infection is initiated by changes on the surface of endothelial cells located in proximity to tissue damage. Inflammatory mediators, such as TNF-α, increase surface expression of adhesive ligands and receptors on the endothelial surface to which neutrophils tether and adhere. Neutrophils then transit through the activated endothelium to reach sites of tissue injury with little lasting vascular injury. However, in cases of sepsis, the interaction of endothelial cells with highly activated neutrophils can cause damage vascular damage. The identification of molecules that are essential for neutrophil diapedesis may reveal targets of therapeutic opportunity for preservation of endothelial function in the presence of critical illness. We tested the hypothesis that inhibition of neutrophil ß1 integrin Very Late Antigen-3 (VLA-3; α3ß1) and/or inhibition of the Tetraspanin (TM4) family member CD151 would protect against neutrophil-mediated loss of endothelial function. METHODS: Blood was obtained from septic patients or healthy donors. Neutrophils were purified and aliquots were treated with/without proinflammatory molecules. Confluent Human Umbilical Vascular Endothelial Cells (HUVECs) were activated with tumor necrosis factor (TNF-α). Electric Cell Impedance Sensing (ECIS) was used to determine monolayer resistance over time after the addition of neutrophils that were treated with blocking antibodies against VLA-3 and/or CD151 or isotype controls. Groups (depending on relevancy) were analyzed by Mann-Whitney test, Wilcoxon test, or repeated measures one-way analysis of variance (ANOVA). RESULTS: Neutrophils from septic patients and neutrophils activated ex vivo reduced endothelial monolayer resistance to a greater extent than neutrophils from healthy donors. Antibody blockade of VLA-3 and/or CD151 significantly reduced activation-associated endothelial damage. Similar findings were demonstrated on fibronectin, collagen I, collagen IV and laminin suggesting that neutrophil surface VLA-3 and CD151 are responsible for endothelial damage regardless of substrata and are likely to be operative in all bodily tissues. CONCLUSION: This report identifies VLA-3 and CD151, on the activated human neutrophil that are responsible for damage to endothelial function. Targeting these molecules in vivo may demonstrate preservation of organ function during critical illness.

Current role of palliative interventions in advanced pancreatic cancer.

Pancreatic adenocarcinoma is the third leading cause of cancer death in the United States. Unfortunately, at diagnosis, most patients are not candidates for curative resection. Surgical palliation, a procedure performed with the intention of relieving symptoms or improving quality of life, comes to the forefront of management. This article reviews the palliative management of unresectable pancreatic cancer, including obstructive jaundice, duodenal obstruction and pain control with celiac plexus block. Although surgical bypasses for both biliary and duodenal obstructions usually achieve good technical success, they result in considerable perioperative morbidity and mortality, even when performed laparoscopically. The effectiveness of self-expanding metal stents for biliary drainage is excellent with low morbidity. Surgical gastrojejunostomy for duodenal obstruction appears to be best for patients with a life expectancy of greater than 2 mo while endoscopic stenting has been shown to be feasible with good symptom relief in those with a shorter life expectancy. Regardless of the palliative procedure performed, all physicians involved must be adequately trained in end of life management to ensure the best possible care for patients.

Whole-Brain Computed Tomographic Perfusion Imaging in Acute Cerebral Venous Sinus Thrombosis.

BACKGROUND: Acute cerebral venous sinus thrombosis (VST) can be difficult to diagnose because of its diverse clinical presentation. The utility of perfusion imaging for diagnosing VST is not well understood. SUMMARY: We retrospectively reviewed cases of acute VST in patients who underwent whole-brain (320-detector-row) computed tomographic (CT) perfusion imaging in combination with craniocervical CT venography. Perfusion maps that were analyzed included cerebral blood volume (CBV), cerebral blood flow (CBF), mean transit time, and time to peak. Among the 10 patients with acute VST included in this study, 9 had perfusion abnormalities. All perfusion abnormalities were localized in areas adjacent to the occluded sinus and did not match typical anterior or posterior circulation arterial territories. Bilateral perfusion deficits were seen in 4 cases. In 2 cases, parenchymal hemorrhage was diagnosed on noncontrast CT imaging; in those cases, focal CBV and CBF were reduced. KEY MESSAGES: Whole-brain CT perfusion imaging with 320-detector-row scanners can further assist in establishing the diagnosis of VST by detecting perfusion abnormalities corresponding to venous and not arterial territories. CT perfusion could assist in the differentiation between focal reversible changes, such as those caused by vasogenic edema, and irreversible changes due to infarction.
