Value of HCC surveillance in a landscape of emerging surveillance options: Perspectives of a multi-stakeholder modified delphi panel.

Hepatocellular carcinoma (HCC) surveillance is recommended by liver professional societies but lacks broad acceptance by several primary care and cancer societies due to limitations in the existing data. We convened a diverse multidisciplinary group of cancer screening experts to evaluate current and future paradigms of HCC prevention and early detection using a rigorous Delphi panel approach. The experts had high agreement on twenty-one statements about primary prevention, HCC surveillance benefits, HCC surveillance harms, and the evaluation of emerging surveillance modalities.

What to do about hepatocellular carcinoma: Recommendations for health authorities from the International Liver Cancer Association.

Hepatocellular carcinoma (HCC) is a major public health problem worldwide for which the incidence and mortality are similar, pointing to the lack of effective treatment options. Knowing the different issues involved in the management of HCC, from risk factors to screening and management, is essential to improve the prognosis and quality of life of affected individuals. This document summarises the current state of knowledge and the unmet needs for all the different stakeholders in the care of liver cancer, meaning patients, relatives, physicians, regulatory agencies and health authorities so that optimal care can be delivered to patients.

Small scale vertical gradients of Arctic ice algal photophysiological properties.

Photosynthetic parameters of phytoplankton and sea ice algae from landfast sea ice of the Chukchi Sea off Point Barrow, Alaska, were assessed in spring 2005 and winter through spring 2006 using Pulse Amplitude Modulated (PAM) fluorometry including estimates of maximum quantum efficiency (F(v)/F(m)), maximum relative electron transport rate (rETR(max)), photosynthetic efficiency (alpha), and the photoadaptive index (E(k)). The use of centrifuged brine samples allowed to document vertical gradients in ice algal acclimation with 5 cm vertical resolution for the first time. Bottom ice algae (0-5 cm from ice-water interface) expressed low F(v)/F(m) (0.

Relationship of physical examination findings and self-reported symptom severity and physical function in patients with degenerative lumbar conditions.

Background And Purpose: Limited data are available to assist clinicians in clinical decision making. The purpose of this study was to examine the relationships of symptom provocation during physical examination (PE) procedures and self-report of symptom severity and function in patients with degenerative lumbar conditions.

Subjects: Twenty-four men and 50 women with chronic low back pain (CLBP) (>6 months duration) were recruited from a university hospital (median age=64.
