Benefits of initial CT staging before sentinel lymph node biopsy in patients with head and neck cutaneous melanoma

BACKGROUND: The value of CT at the time of diagnosis for patients with cutaneous head and neck melanoma clinically asymptomatic for metastatic disease is unclear. METHODS: A retrospective medical chart review was performed on 198 consecutive patients identified with primary T1b-T4b head and neck melanoma clinically asymptomatic for metastatic disease referred for sentinel lymph node biopsy proceduBACKGROUND: The value of CT at the time of diagnosis for patients with cutaneous head and neck melanoma clinically asymptomatic for metastatic disease is unclear.METHODS: A retrospective medical chart review was performed on 198 consecutive patients identified with primary T1b-T4b head and neck melanoma clinically asymptomatic for metastatic disease referred for sentinel lymph node biopsy procedur

Pay for performance associated with increased volume of medication reviews but not with less inappropriate use of medications among the elderly – an observational study

Objective: A pay for performance programme was introduced in 2009 by a Swedish county with 1.6 million inhabitants. A process measure with payment linked to coding for medication reviews among the elderly was adopted. We assessed the association with inappropriate medication for five years after baseline.Design and setting: Observational study that compared medication for elderly patients enrolled

Primärvårdens resurser, styrning och organisation : En jämförelse av villkor och förhållanden i Danmark, Norge, Nederländerna och Storbritannien

Myndigheten för vård- och omsorgsanalys (Vårdanalys) har vänt sig till professor Anders Anell vid Lunds universitet för att genomföra fallstudier av primärvården i fyra länder: Danmark, Norge, Nederländerna och Storbritannien. Denna promemoria är hans redovisning av arbetet och är ett underlag till Vårdanalys rapport En primär angelägenhet. Kunskapsunderlag för en stärkt primärvård med patienten i

Social and spatial effects on genetic variation between foraging flocks in a wild bird population

Social interactions are rarely random. In some instances, animals exhibit homophily or heterophily, the tendency to interact with similar or dissimilar conspecifics, respectively. Genetic homophily and heterophily influence the evolutionary dynamics of populations, because they potentially affect sexual and social selection. Here, we investigate the link between social interactions and allele freq

GAD65 antigen therapy in recently diagnosed type 1 diabetes mellitus

BACKGROUND: The 65-kD isoform of glutamic acid decarboxylase (GAD65) is a major autoantigen in type 1 diabetes. We hypothesized that alum-formulated GAD65 (GAD-alum) can preserve beta-cell function in patients with recent-onset type 1 diabetes. METHODS: We studied 334 patients, 10 to 20 years of age, with type 1 diabetes, fasting C-peptide levels of more than 0.3 ng per milliliter (0.1 nmol per li

Equipped to cope with climate change : Traits associated with range filling across European taxa

In order to understand the ecological effects of climate change it is essential to forecast suitable areas for species in the future. However, species' ability to reach potentially suitable areas is also critical for species survival. These 'range-shift' abilities can be studied using life-history traits related to four range-shift stages: emigration, movement, establishment, and proliferation. He

Spatially Coupled Turbo-Like Codes

In this paper, we introduce the concept of spatially coupled turbo-like codes (SC-TCs) as the spatial coupling of a number of turbo-like code ensembles. In particular, we consider the spatial coupling of parallel concatenated codes, introduced by Berrou et al., and that of serially concatenated codes (SCCs), introduced by Benedetto et al. Furthermore, we propose two extensions of braided convoluti

University-society collaboration on the agenda : The rhetoric of expectations

This paper aims to contribute to the knowledge on how the concept of ‘collaboration’ is being produced and reproduced – and filled with meaning – as it is articulated in news content and opinion articles about the organisation of knowledge production within higher education in Sweden. We build on a textual analysis on the public discussion in the aftermath of the announcement of the research polic

Teachers’ Assessment and grading Practices in upper secondary Science Classrooms in Sweden : The Teachers’ and Students’ Perspectives

This dissertation acknowledges that accountability of educators for the grades they assign is a part of the foundation for a meritocratic society, based on fairness in judging merit and, therefore, in assigning grades. In this view, any grade obtained by any student must be both reliable and valid. This, in turn, implies that the process of assessment of students’ work on which the grade is based

Pericytes secrete pro-regenerative molecules in response to platelet-derived growth factor-BB

Brain pericytes not only maintain the anatomical, biochemical and immune blood-brain barrier, but display features of mesenchymal stem cells (MSCs) in vitro. MSCs have pro-regenerative properties attributed to their secretome. However, whether also brain pericytes possess such pro-regenerative capacities is largely unknown. Here we characterize the secretome and microvesicle (MV) release of human

Banking Secrecy and Global Finance : Economic and Political Issues

A 2009 G20 official document stated that the era of banking secrecy is over but is it? If banking secrecy is the result of market mechanisms, it suggests that worldwide demand and supply are likely to remain for a long time to come. Since the Global Financial Crisis, many countries have fought to combat banking secrecy, yet it permeates both national and international industries, and global effort
