Treatment and outcome in pancreatic pseudocysts

Objective. Pancreatic pseudocyst is a common complication of both acute and chronic pancreatitis. The aim of the present study was to evaluate the efficacy and complications of different treatment regimens. Material and methods. All patients >= 15 years of age admitted to Lund University Hospital from 1994 to 2003 with pancreatic pseudocysts were analysed retrospectively. Pseudocysts were defined

Introduction to biological mass spectrometry: Determining identity and species of origin of two proteins

We describe a laboratory exercise that is designed to give advanced undergraduate students in analytical chemistry a meaningful introduction to biological mass spectrometry. We ask the students to solve a mystery: given two proteins, what are they, and from which animals do they originate? This exercise involves use of two mass spectrometers available in our institution: a fairly basic matrix-assi

Difficulties in performing leisure activities among persons with newly diagnosed rheumatoid arthritis: a prospective, controlled study.

Objective. To compare leisure activities and associated factors in a group with recent onset RA and matched community-derived controls, to examine whether leisure activities are altered during the early years of disease and to seek predictors. Methods. One hundred and forty-seven consecutive persons with early RA were followed for 0.9-5.9 yr. One hundred and forty-four RA patients were compared cr

Analysis of the surface electrocardiogram for monitoring and predicting antiarrhythmic drug effects in atrial fibrillation

Specific antiarrhythmic therapy with class I and III drugs for atrial fibrillation (AF) conversion and prevention of its recurrence is frequently utilized in clinical practice. Besides being only moderate effective, the utilization of antiarrhythmic drugs may be associated with serious side effects. In the clinical setting it is difficult to directly evaluate the effects of antiarrhythmic drugs on

Assisting teens with asthma to take command

To meet and work with teenagers may be a challenge for caregivers as adolescence is a period when youths try to establish autonomy. Although asthma is an increasing problem worldwide, few studies have addressed professional caregivers' motives and actions. Therefore, the aim of this study was to describe professional caregivers' strategies in their work with teenagers with asthma. Grounded theory,

Molecular characterization of 3 MHC class II B haplotypes in the ring-necked pheasant

We investigated the class II B genes in a free-ranging population of the ring-necked pheasant Phasianus colchicus by a combination of restriction fragment length polymorphism (RFLP), polymerase chain reaction (PCR), and DNA sequencing. Special attention was paid to the variation in the second exon, which encodes the peptide-binding beta(i)-domain. The population was introduced, but it still exhibi

Recommendations for an update of the current (2001) regulatory requirements for registration of drugs to be used in the treatment of osteoporosis in postmenopausal women and in men

Recent advances in the understanding of the epidemiology of osteoporosis suggest that certain parts of the current European guidelines for the registration of drugs in osteoporosis might be no longer substantiated. The object of this review is to provide the European regulatory authorities with an evidence-based working document providing suggestions for the revision of the "Note for guidance for

Engine knock prediction using multi zone model for spark ignition engines

Autoignition in SI engines is an abnormal combustion mode and may lead to engine knock in SI engines. Knock may cause damage and it is a source of noise in engines. It limits the compression ratio of the engine and a low compression ratio means low fuel conversion efficiency of the engine. In this paper a multi zone model based on an existing two zone model Hajireza et al., [1 and 12] and Stenlaas

Linear Time-Varying Systems : Modeling and Reduction

Linear time-invariant models are widely used in the control community. They often serve as approximations of nonlinear systems. For control purposes linear approximations are often good enough since feedback control systems are inherently robust to model errors. In this thesis some of the possibilities for linear time-varying modeling are studied. In the thesis it is shown that the balanced trunca

The Demand for Health and the Contingent Valuation Method

The theoretical part develops Michael Grossman’s dynamic demand-for-health model by (a) letting the depreciation rate depend upon the level of health, (b) allowing a continuous set of health states, (c) introducing uncertainty (by letting health be a stochastic variable), (d) introducing social and private insurance and (e) releasing the assumption of an isoperimetric budget constraint. Beside the

Information and communication in society

In late modernity, the media is one of the most important social institutions in influencing people's knowledge, perceptions and actions. The media supply citizens with health-related messages and contribute thereby to their health development. The abundant flow of health-related messages, however, makes it difficult for the individual to separate good and reliable information from information of

In Defence of the Open Question Argument

The purpose of this paper is to defend G. E. Moore's open question argument, understood as an argument directed against analytic reductionism, the view that moral properties are analytically reducible to non-moral properties. In the first section I revise Moore's argument in order to make it as plausible and resistant against objections as possible. In the following two sections I develop the argu

Batch Control and Diagnosis

Batch processes are becoming more and more important in the chemical process industry, where they are used in the manufacture of specialty materials, which often are highly profitable. Some examples where batch processes are important are the manufacturing of pharmaceuticals, polymers, and semiconductors. The focus of this thesis is exception handling and fault detection in batch control. In the

Safety and efficacy of a high cumulative dose of salbutamol inhaled via Turbuhaler or via a pressurized metered-dose inhaler in patients with asthma

An open, crossover and randomized study was carried out to compare the safety and efficacy of salbutamol inhaled using the dry-powder inhaler Turbuhaler, and using a pressurized metered-dose inhaler (pMDI). Twelve patients with moderate to severe asthma, aged 47-68 years, were included in the study. On two separate days, patients received a total dose of 1600 micrograms of salbutamol administered
