European Society of Hypertension practice guidelines for home blood pressure monitoring.
2010
Self-monitoring of blood pressure by patients at home (home blood pressure monitoring (HBPM)) is being increasingly used in many countries and is well accepted by hypertensive patients. Current hypertension guidelines have endorsed the use of HBPM in clinical practice as a useful adjunct to conventional office measurements. Recently, a detailed consensus document on HBPM was published by the European Society of Hypertension Working Group on Blood Pressure Monitoring. However, in daily practice, briefer documents summarizing the essential recommendations are needed. It is also accepted that the successful implementation of clinical guidelines in routine patient care is dependent on their acc…
Identification of a discrete neuronal circuit that relays insulin signaling into the brain to regulate glucose homeostasis
2021
Abstract26RFa (QRFP) is a biologically active peptide that regulates glucose homeostasis by acting as an incretin and by increasing insulin sensitivity at the periphery. 26RFa is also produced by a neuronal population localized in the hypothalamus. In the present study, we have investigated whether the 26RFa neurons may be involved in the hypothalamic regulation of glucose homeostasis. Our data indicate that 26RFa, i.c.v. injected, induces a robust antihyperglycemic effect associated with an increase of insulin production by the pancreatic islets. In addition, we found that insulin strongly stimulates 26RFa expression and secretion by the hypothalamus. RNAscope experiments revealed that neu…
Secretagogues Modulate the Calcium Concentration in the Endoplasmic Reticulum of Insulin-secreting Cells
1999
The precise regulation of the Ca2+ concentration in the endoplasmic reticulum ([Ca2+]er) is important for protein processing and signal transduction. In the pancreatic beta-cell, dysregulation of [Ca2+]er may cause impaired insulin secretion. The Ca2+-sensitive photoprotein aequorin mutated to lower its Ca2+ affinity was stably expressed in the endoplasmic reticulum (ER) of rat insulinoma INS-1 cells. The steady state [Ca2+]er was 267 +/- 9 microM. Both the Ca2+-ATPase inhibitor cyclopiazonic acid and 4-chloro-m-cresol, an activator of ryanodine receptors, caused an almost complete emptying of ER Ca2+. The inositol 1,4,5-trisphosphate generating agonists, carbachol, and ATP, reduced [Ca2+]e…
Translation and testing of the Risk Assessment Pressure Ulcer Sore scale used among residents in Norwegian nursing homes.
2012
Published version of an article in the journal: BMJ Open. Also available from the publisher at: http://dx.doi.org/10.1136/bmjopen-2012-001575 Open access Objective. The purpose of this study was to translate and test the psychometric properties of the Norwegian-language version of the Risk Assessment Pressure Sore scale. Background. Risk assessment scales for pressure ulcer prevention have become an aspect of quality improvement in healthcare, but their effectiveness depends on the reliability and validity of the scale. Methods. A convenience sample of 481 residents in 15 nursing homes in rural Norway was included between January and June 2007. The English-language version of the Risk Asses…
Home treatment of fragile patients with acute pulmonary embolism: a subgroup analysis of the multinational home treatment of pulmonary embolism (HoT-…
2020
Abstract Background and aims Subgroup analyses of randomized trials and cohort studies on direct oral anticoagulants (DOACs) suggested that single direct drug treatment may be effective and safe in elderly and “fragile” patients with acute pulmonary embolism (PE). In a post-hoc analysis of HoT-PE, a prospective multicenter management trial, we studied whether early discharge and home treatment of acute PE is effective and safe in these patients. Methods HoT-PE enrolled patients with acute PE classified as being at low risk based on the modified Hestia criteria and the absence of right ventricular dysfunction. The primary efficacy outcome was symptomatic recurrent VTE, or PE-related death wi…
Effectiveness of a home exercise programme in low back pain: a randomized five-year follow-up study
2007
Background and Purpose. Therapeutic exercise has been shown to be beneficial in decreasing pain and in increasing functioning in patients with chronic low back pain. However, longitudinal follow-up studies are small in number, and often limited in the numbers of subjects due to drop-outs. In addition there is a shortage of real control groups in most cases. The purpose of the present study was to describe long-term changes in intensity of low back pain and in functioning for two study groups five years after undertaking a home exercise programme. Method. This was a randomized follow-up study over five years. Fifty-seven subjects were reassessed with questionnaires five years after their ini…
Precapillary Servo Control of Blood Pressure and Postcapillary Adjustment of Flow to Tissue Metabolic Status
1996
Background There are several shortcomings in current understanding of how the microvasculature maintains tissue homeostasis. Presently unresolved issues include (1) integration of the potentially conflicting needs for capillary perfusion and hydrostatic pressure regulation, (2) an understanding of signal transmission pathways for conveying information about tissue energetic status from undersupplied tissue sites to the arterioles, (3) accounting for the experimentally observed interrelations between precapillary and postcapillary resistances, and (4) an explanation of how precise local adjustment of perfusion to metabolic demands is achieved. Methods and Results A novel conceptualization o…
Relationship of Cerebral Blood Flow Disturbances with Brain Oedema Formation
1993
Brain oedema is an important factor which compromises maintenance of the cerebral blood flow. Conversely, primary blood flow disturbances are leading to brain oedema. The mechanisms underlying blood flow impairment by brain oedema are associated with an increased regional tissue pressure in proportion to the degree of water accumulation in the parenchyma. The release of vasoactive mediator compounds might be considered in addition. Primary disturbances of the cerebral blood flow, such as focal or global cerebral ischaemia are leading to an increased cerebral water content. A decrease of the cerebral blood flow to ca. 40% of normal or below has been found to result in the development of brai…
Acid-Base Balance after Continent Urinary Diversion in Childhood – Risk of Imbalance Despite Medication
2010
Purpose Continent urinary-intestinal diversion can lead to alterations of the acid-base balance, acutely and chronically, the latter possibly causing bone demineralization. Annual check-ups have therefore been recommended for decades. Material and Methods At our institution, 89 children underwent continent urinary diversion by ileocecal pouch or bladder substitution between 1984 and 2006. In 58 of these patients (age 3-17 y., median 13.9 y.), we performed a minimum of 3 (range 3-23, median 6.2) consecutive annual blood-gas analyses over a follow-up period of up to 23 years (median 11.0) after surgery. At a base excess (BE) (as marker of the acid-base-balance) value below -2.5 mmol/l, treatm…
Mutations in the NKX2.5 Gene and the PAX8 Promoter in a Girl with Thyroid Dysgenesis
2011
Screening of the known candidate genes involved in thyroid organogenesis has revealed mutations in a small subset of patients with congenital hypothyroidism due to thyroid dysgenesis (TD).We studied a girl with TD who had mutations in two transcription factors involved in thyroid development.Sequencing analysis of candidate genes involved in thyroid gland development revealed a new paternally inherited heterozygous mutation in the NKX2.5 gene (S265R) and a new maternally inherited heterozygous mutation in the PAX8 promoter region (-456CT). Both parents and a brother, who was also heterozygous for both mutations, were phenotypically normal. Immunofluorescence microscopy showed a correct nucl…
