The development of exocrine pancreas function was studied in Swedish Landrace pigs surgically fitted with a chronic pancreatic duct catheter and a duodenal re-entrant cannula. The juice secretion and output of total protein and trypsin activity were followed before (basal secretion) and after feeding (postprandial secretion) during the first 1-13 weeks of life. The results showed that throughout t

Using electroimmunoassay the levels of the individual protease inhibitors, α2-macroglobulin f, α2-macroglobulin s, inter-α-trypsin inhibitor, α1-protease inhibitor and α2-antitrypsin were studied in the serum and the amniotic fluid during the fetal and postnatal development of the pig. High concentrations, far above the adult ones, of α2-antitrypsin and especially α1-protease inhibitor, were obser

Protease inhibitors and protease (caseinolytic, elastinolytic and esterolytic) activity were analysed in 190 milk samples from 94 mothers from day 1 to day 160 after delivery The main protease inhibitors in human milk are α1-antichymotrypsin and α1-antitrypsin. As measured by electroimmunoassay, the level of α1-antichy-motrypsin in day 1 colostrum was higher than that in normal serum. Trace amount

The intestinal transmission of two macromolecular markers, of similar molecular weight but different susceptibility to proteolytic digestion, was investigated in the neonatal pig. Piglets of varying age (0 h-7 days old) were given a mixture of bovine scrum albumin (BSA) and fluorescein-isothiocyanalc labelled dextran 70,000 (FiTC-D 70) by stomach tube, and the scrum concentrations were determined

Monoclonal gammopathy of undetermined significance (MGUS) is the precursor of multiple myeloma (MM) and related disorders. MGUS is characterized by asymptomatic paraproteinemia. In some cases, multiple paraproteins can be identified but the clinical implications of this phenomenon are poorly understood. In this study, we aim to inform the approach to this challenging MGUS subgroup by utilizing dat

There is some evidence that a prior cancer is a risk factor for the development of multiple myeloma (MM). If this is true, prior cancer should be associated with a higher prevalence or increased progression rate of monoclonal gammopathy of undetermined significance (MGUS), the precursor of MM and related disorders. Those with a history of cancer might therefore constitute a target population for M

Serum free light chain (FLC) concentration is greatly affected by kidney function. Using a large prospective population-based cohort, we aimed to establish a reference interval for FLCs in persons with chronic kidney disease (CKD). A total of 75422 participants of the iStopMM study were screened with serum FLC, serum protein electrophoresis and immunofixation. Estimated glomerular filtration rate

BACKGROUND: Both postoperative acute kidney injury (AKI) and preoperative chronic kidney disease (CKD) are associated with significantly worse outcomes following surgery. The relationship of both of these conditions with each other and with CKD progression after surgery remains poorly studied. Our objective was to assess if there was an interaction between preoperative kidney function estimated by

AIMS: To evaluate the validity of recorded chronic disease diagnoses in Icelandic healthcare registries.METHODS: Eight different chronic diseases from multiple sub-specialties of medicine were validated with respect to accuracy, but not to timeliness. For each disease, 30 patients with a recorded diagnosis and 30 patients without the same diagnosis were randomly selected from >80,000 participants

BACKGROUND: Mild cases of acute kidney injury (AKI) are identified by a small rise in serum creatinine (SCr) according to the KDIGO AKI definition. The aim of this study was to examine the long-term outcomes of individuals with mild AKI.Methods. This was a retrospective cohort study of all adult patients who underwent abdominal, cardiothoracic, vascular or orthopaedic surgery at Landspitali-The Na

Background Limited data exist on long-term survival of patients requiring admission to intensive care units (ICUs). The aim of this study was to investigate long-term survival of ICU patients in Iceland and assess changes over a 15-year period. Methods Data were collected on age, gender, admission cause, length of stay, comorbidities, mechanical ventilation and survival of patients 18 years and ol

IMPORTANCE: The number of patients prescribed long-term opioids and benzodiazepines and complications from their long-term use have increased. Information regarding the perioperative outcomes of patients prescribed these medications before surgery is limited.OBJECTIVE: To determine whether patients prescribed opioids and/or benzodiazepines within 6 months preoperatively would have greater short- a

BACKGROUND: The aim of this study was to examine different definitions of renal recovery following postoperative acute kidney injury (AKI) and how these definitions associate with survival and the development and progression of chronic kidney disease (CKD).METHODS: This was a retrospective study of all patients who underwent abdominal, cardiothoracic, vascular, or orthopedic surgery at a single un

BACKGROUND: We studied the incidence and risk factors of acute kidney injury (AKI) following coronary angiography (CA) and examined short- and long-term outcomes of patients who developed AKI, including progression of chronic kidney disease (CKD).METHODS: This was a retrospective study of all patients undergoing CA in Iceland from 2008 to 2015, with or without percutaneous coronary intervention. A

BACKGROUND: Acute kidney injury (AKI) is a serious complication after major surgical procedures. We examined the incidence, risk factors, and mortality of patients who sustained AKI after abdominal surgery in a large population-based cohort.METHODS: All patients who underwent open and laparoscopic abdominal surgery (excluding genitourinary and abdominal vascular procedures), between 2007 and 2014

AIM: Acute kidney injury (AKI) is a common complication of medical and surgical interventions in hospitalized patients and associates with high mortality. Our aim was to examine renal recovery and long-term survival and time trends in AKI survival.METHODS: Changes in serum creatinine (SCr) were used to define AKI in patients at Landspitali University Hospital in Iceland from 1993 to 2013.
