Evidence for time dependent variation of glucagon secretion in mice.

Glucose metabolism is subjected to diurnal variation, which might be mediated by alterations in the transcription pattern of clock genes and regulated by hormonal factors, as has been demonstrated for insulin. However, whether also glucagon is involved in the diurnal variation of glucose homeostasis is not known. We therefore examined glucagon secretion after meal ingestion (meal tolerance test) a

Person--environment fit predicts falls in older adults better than the consideration of environmental hazards only.

Objective: To test the hypotheses that the empirical consideration of objective person-environment fit in the home environment is a stronger predictor of indoor falls among older adults than the assessment of environmental barriers only, and that perceived aspects of home play a role as predictors for falls.Design: Survey study with data collection at home visits, followed up by self-reports about

Socioeconomic Position, Comorbidity, and Mortality in Aortic Aneurysms: A 13-Year Prospective Cohort Study.

BACKGROUND: To evaluate factors associated with incidence and 3-year all-cause mortality in patients with aortic aneurysm (AA). The design is sex and age-stratified (60-79 and 80-90 years) prospective cohort. By using the population register, we constituted a cohort of all men and women born between 1900 and 1930 and living in Scania by 1991, and followed them for 13 years. Identification of AA wa

Family members' experiences of personal assistance given to a relative with disabilities.

Personal assistance is a type of home care common to many countries even though entitlement and legislative framework may vary from country to country. At present, there exists no knowledge about the family members' experiences of such assistance; therefore, the aim of this study was to investigate family members' experiences of personal assistance given to a relative of working age with a functio

Impact of Cigarette Smoking on Cancer Risk in the European Prospective Investigation into Cancer and Nutrition Study.

PURPOSEOur aim was to assess the impact of cigarette smoking on the risk of the tumors classified by the International Agency for Research on Cancer as causally associated with smoking, referred to as tobacco-related cancers (TRC). METHODSThe study population included 441,211 participants (133,018 men and 308,193 women) from the European Prospective Investigation Into Cancer and Nutrition. We inve

Hemodynamics and jugular venous oxygen saturation during carotid endarterectomy: a comparison between general and locoregional anesthesia.

AIM: To study hemodynamic and blood oxygenation changes in patients undergoing carotid endarterectomy (CEA) under general (GA) or locoregional (LRA) anesthesia. METHODS: Prospective non-randomized study including 50 patients undergoing CEA (31 men, mean age 72 (range 50-84) years-old under GA (N.=23) or LRA (N.=27). Systemic blood pressure, ECG, venous oxygen saturation in the ipsilateral jugular

Pre-Diagnostic Levels of Anionic Trypsinogen, Cationic Trypsinogen, and Pancreatic Secretory Trypsin Inhibitor in Relation to Pancreatic Cancer Risk.

Background/Aims: Experimental studies have suggested that trypsinogen may enhance tumor progression and that the ratio between anionic trypsinogen and cationic trypsinogen (HAT/HCT) and between the sum of trypsinogens and pancreatic secretory trypsin inhibitor (PSTI) ((HAT + HCT)/PSTI) are disturbed in patients with pancreatic cancer. The aim of this study was to investigate if pre-diagnostic leve

Male infertility and prostate cancer risk: a nested case-control study.

The pathogenesis of prostate cancer is unclear, although experimental evidence implicates androgens as playing an important role. Infertile men frequently suffer from some degree of hypogonadism and may hence be hypothesized to be at lower risk of developing prostate cancer than fertile men. To test this hypothesis, we conducted a case-control study nested within "the Malmö Diet and Cancer Study"

Can CSF biomarkers or pre-treatment progression rate predict response to cholinesterase inhibitor treatment in Alzheimer's disease?

OBJECTIVE: The main objective of this study was to investigate possible predictors of response to cholinesterase inhibitor (ChEI) treatment, including pre-treatment progression rates and levels of the cerebrospinal fluid (CSF) biomarkers. A secondary objective was to evaluate whether treatment with ChEI changed progression. METHODS: Out-patient individuals (n = 191) with the clinical diagnosis of

Nesfatin-1 stimulates glucagon and insulin secretion and beta cell NUCB2 is reduced in human type 2 diabetic subjects.

Nesfatin-1 is a novel anorexigenic regulatory peptide. The peptide is the N-terminal part of nucleobindin 2 (NUCB2) and is expressed in brain areas regulating feeding. Outside the brain, nesfatin-1 expression has been reported in adipocytes, gastric endocrine cells and islet cells. We studied NUCB2 expression in human and rodent islets using immunocytochemistry, in situ hybridization and western b

Overweight in relation to tumour size and axillary lymph node involvement in postmenopausal breast cancer patients-differences between women invited to vs. not invited to mammography in a randomized screening trial.

OBJECTIVES: Overweight is associated with advanced stage at diagnosis in breast cancer patients. This could be explained by specific tumour characteristics or tumour promoting factors in the obese, but a diagnostic delay could also be of importance. Mammographic screening has caused a change towards diagnosis of less advanced tumours. This study investigates invitation to mammographic screening an

Switching From High-Fat to Low-Fat Diet Normalizes Glucose Metabolism and Improves Glucose-Stimulated Insulin Secretion and Insulin Sensitivity But Not Body Weight in C57BL/6J Mice.

OBJECTIVES: Environmental factors such as a high-fat diet contribute to type 2 diabetes and obesity. This study examined glycemia, insulin sensitivity, and β-cell function after switching from a high-fat diet to a low-fat diet in mice. METHODS: C57BL/6J mice were fed a high-fat diet or low-fat diet for 18 months, after which mice on the high-fat diet either maintained this diet or switched to a lo

α 1-antitrypsin enhances insulin secretion and prevents cytokine-mediated apoptosis in pancreatic β-cells.

α1-antitrypsin (AAT) is a serine protease inhibitor, which recently has been shown to prevent type 1 diabetes (T1D) development, to prolong islet allograft survival and to inhibit β-cell apoptosis in vivo. It has also been reported that T1D patients have significantly lower plasma concentrations of AAT suggesting the potential role of AAT in the pathogenesis of T1D. We have investigated whether pl

Body mass index and breast cancer survival in relation to the introduction of mammographic screening.

AIMS: Mammographic screening reduces mortality in breast cancer. It is not known if this reduction is more pronounced in certain groups. Obesity has been associated with worse survival following breast cancer diagnosis. This study investigates BMI in relation to breast cancer mortality, and if this association is affected by invitation to mammographic screening. METHODS: In 1976, a randomised mamm
