Biomagnification of mercury and selenium in two lakes in southern Norway.

We have investigated bioaccumulation and trophic transfer of both mercury (Hg) and selenium (Se) in two lakes in southern Norway to reveal a suggested mitigating effect of Se on Hg biota accumulation. The study included analysis of total Se (Se), total Hg (Hg), and methyl-mercury (MeHg) in water, littoral and pelagic invertebrates and perch (Perca fluviatilis), together with stable isotope analysis (δ(15)N and δ(13)C) in biota. Mean dissolved Se ranged from 22 to 59ngL(-1), while Hg and MeHg in lake water ranged from 1 to 3ngL(-1) and 0.

Communicative challenges in the home care of older persons - a qualitative exploration.

Aim: To explore communicative challenges in encounters between nurse assistants and older persons during home care visits.

Background: The older population is increasing worldwide. Currently, there is a shift in care for older people from institutional care to home care.

Stuck between a rock and a hard place: the work situation for nurses as leaders in municipal health care.

Background: The paper aims to present how nursing leaders in the municipal health care perceive the interaction with and support from their superiors and peers. The paper further aims to identify the leaders' vulnerability and strength at work in the current situation of shortage of manpower and other resources in the health care sector. This is seen through the lens of self-determination theory.

Communication during haematological consultations; patients' preferences and professionals' performances.

Many patients with haematological malignancies experience barriers in clinical communication. Reaching effective communication is of great importance as it has been linked to a range of improved patient outcomes such as satisfaction, compliance to treatment, perceived quality of life and physical and mental health. To get a better understanding how communication in haematological consultations can be improved, the current study focussed on patients' preferences and perceived performances regarding the communicative behaviour of their health care professional.

Effect of Direct Glare on Orbicularis Oculi and Trapezius During Computer Reading.

Purpose: Unfavorable visual conditions during computer work may affect development of both eyestrain and musculoskeletal pain in the neck and shoulder area. The aim of the study was to investigate how direct glare affects symptom development, muscle activity, and muscle blood flow in m. orbicularis oculi and m.

Patient information and emotional needs across the hip osteoarthritis continuum: a qualitative study.

Background: Osteoarthritis (OA) is the most common form of arthritis worldwide, affecting a growing number of people in the ageing populations. Currently, it affects about 50 % of all people over 65 years of age. There are no disease-modifying treatments for OA; hence preference-sensitive treatment options include symptom reduction, self-management and surgical joint replacement for suitable individuals.

The effects of wildfire on mercury and stable isotopes (δ(15)N, δ(13)C) in water and biota of small boreal, acidic lakes in southern Norway.

Effects of wildfire on main water chemistry and mercury (Hg) in water and biota were studied during the first 4 post-fire years. After severe water chemical conditions during hydrological events a few months following the wildfire, the major water chemical parameters were close to pre-fire conditions 4 years after the fire. Concentrations of total Hg and methyl Hg in the surface water 4 years after the fire ranged between 1.

The forest as a classroom: preparing for mental health practice.

Background: Positive effects of physical activity, health promotion and disease prevention, in treatment of mental illnesses are well documented. Mental health practice for nursing students highlights the important connection between physical activities and mental health. This study aims to examine the outcome from nursing students' participation using The forest as a classroom.

Reconstruction of paediatric organ doses from axial CT scans performed in the 1990s - range of doses as input to uncertainty estimates.

Objective: To assess the range of doses in paediatric CT scans conducted in the 1990s in Norway as input to an international epidemiology study: the EPI-CT study, http://epi-ct.iarc.fr/ .
