- Rationale, aims and objectivesEvidence-informed healthcare is the fundament for prac-tice, whereby guidelines based on the best available evidence should assist health profes-sionals in managing patients. Patients seeking care for acute abdominal pain form acommon group in acute care settings worldwide, for whom decision-making and timelytreatment are of paramount importance. There is ambiguity about the existence, use andcontent of guidelines for patients with acute abdomen. The objective was to describe andcompare guidelines and management of patients with acute abdomen in different settingsacross the acute care delivery chain in Sweden.MethodA national cross-sectional design was used. Twenty-nine ambulance stations, 17emergency departments and 33 surgical wards covering all six Swedish health regions wereincluded, and 23 guidelines were quality appraised using the validated Appraisal of Guide-lines for Research & Evaluation II tool.ResultsThere is a lack of guidelines in use for the management of this large group of pa-tients between and within different healthcare areas across the acute care delivery chain.The quality appraisal identified that several guidelines were of poor quality, especiallythe in-hospital ones. Further, range orders for analgesics are common in the ambulance ser-vices and the surgical wards, but are seldom present in the emergency departments. Also,education in pain management is more common in the ambulance services. Thesefindingsare noteworthy as, hypothetically, the same patient could be treated in three different waysduring the same care episode.ConclusionsThere is an urgent need to develop high-quality evidence-based clinicalguidelines for this patient group, with the entire care process in focus

- BACKGROUND:Insulin-like growth factor 1 (IGF-1) may influence cellular growth, differentiation and secretion.MATERIAL AND METHODS:Cryosectioned normal human adrenal glands (n = 6), cortical adenoma (n = 21), and carcinoma (n = 17) were stained immunohistochemically for IGF-1 and its receptor, and human adrenocortical cancer cells expressing the receptor were analysed for influences on proliferation.RESULTS:Normal cortical parenchyma generally displayed faint IGF-1 reactivity and intracellular receptor staining. Similar labelling encompassed the adenomas, but only 6 of them were receptor reactive. IGF-1 expression was conspicuous in 11 carcinomas, and 6 of them displayed cell surface receptor reactivity. All aldosterone producing lesions were receptor antibody unreactive. Recombinant IGF-1 dose-dependently stimulated the cell proliferation, and this effect was reversed by the receptor antibody.CONCLUSION:IGF-1 may interact with function and proliferation of the human adrenal cortex with particular reference to cortical carcinomas lacking discernible aldosterone excess.

- The purpose of the study was to evaluate PET with the tracer 11C-metomidate as a method to identify adrenal cortical lesions.METHODS:PET with 11C-metomidate was performed in 15 patients with unilateral adrenal mass confirmed by CT. All patients subsequently underwent surgery, except 2 who underwent biopsy only. The lesions were histopathologically examined and diagnosed as adrenal cortical adenoma (n = 6; 3 nonfunctioning), adrenocortical carcinoma (n = 2), and nodular hyperplasia (n = 1). The remaining were noncortical lesions, including 1 pheochromocytoma, 1 myelolipoma, 2 adrenal cysts, and 2 metastases.RESULTS:All cortical lesions were easily identified because of exceedingly high uptake of 11C-metomidate, whereas the noncortical lesions showed very low uptake. High uptake was also seen in normal adrenal glands and in the stomach. The uptake was intermediate in the liver and low in other abdominal organs. Images obtained immediately after tracer injection displayed high uptake in the renal cortex and spleen. The tracer uptake in the cortical lesions increased throughout the examination. For quantitative evaluation of tracer binding in individual lesions, a model with the splenic radioactivity concentration assigned to represent nonspecific uptake was applied. Values derived with this method, however, did show the same specificity as the simpler standardized uptake value concept, with similar difference observed for cortical versus noncortical lesions.CONCLUSION:PET with 11C-metomidate has the potential to be an attractive method for the characterization of adrenal masses with the ability to discriminate lesions of adrenal cortical origin from noncortical lesions.

- Purpose:The purpose of the study was to evaluate the potential role of PET with the adrenocortical-specific tracer 11C-metomidate in the characterization of incidentally found adrenal cortical lesions and in adrenocortical carcinomas.Methods:PET with 11C-metomidate was performed in 15 patients with unilateral adrenal mass confirmed by CT (incidentalomas) and in 9 additional patients with adrenocortical cancer. All incidentalomas subsequently underwent surgery, except 2 subjected to biopsy only. These lesions were histopathologically examined and diagnosed as adrenal cortical adenoma (n = 6; 3 nonfunctioning), adrenocortical carcinoma (n = 2) and nodular hyperplasia (n = 1). The remaining were non-cortical lesions including 1 pheochromocytoma, 1 myelolipoma, 2 adrenal cysts, and 2 metastases.Results:All lesions, except 1, with an adrenocortical origin were easily identified due to exceedingly high uptake of 11C-metomidate, whereas the non-cortical lesions showed very low uptake. The 1 false negative was a cancer that at surgery was found to be extensively necrotic. High uptake was also seen in normal adrenal glands. The tracer uptake kinetics indicated trapping of the tracer in the cortical lesions. For quantitative evaluation of tracer binding in individual lesions, the simple SUV concept was found to be equally accurate as more elaborate kinetic analyses.Conclusion:The patients presented and altogether over 40 PET investigations have demonstrated 11C-metomidate to be an attractive tracer for the characterization of adrenal masses with the ability to discriminate lesions of adrenal cortical origin from non-cortical lesions. Additionally the method allows the assessment of metastases from adrenocortical cancers, and the very high contrast has allowed partial whole-body examinations.

- OBJECTIVES: To examine the risk of developing adrenal carcinomas and clinically overt hypersecreting tumours during short-term follow-up in patients with adrenal incidentalomas. DESIGN: 229 (98 males and 131 females) patients with adrenal incidentalomas were investigated in a prospective follow-up study (median time 25 months; range 3-108 months). The patients were registered between January 1996 and July 2001 and followed until December 2004. Twenty-seven Swedish hospitals contributed with follow-up results. METHODS: Diagnostic procedures were undertaken according to a protocol including reinvestigation with computed tomography scans after 3-6 months, 15-18 months and 27-30 months, as well as hormonal evaluation at baseline and after 27-30 months of follow-up. Operation was recommended when the incidentaloma size increased or if there was a suspicion of a hypersecreting tumour. RESULTS: The median age at diagnosis of the 229 patients included in the follow-up study was 64 years (range 28-84 years) and the median size of the adrenal incidentalomas when discovered was 2.5 cm (range 1-8 cm). During the follow-up period, an increase in incidentaloma size of > or =0.5 cm was reported in 17 (7.4%) and of > or =1.0 cm was reported in 12 (5.2%) of the 229 patients. A decrease in size was seen in 12 patients (5.2%). A hypersecreting tumour was found in 2% of the hormonally investigated patients: Cushing's syndrome (n = 2) and phaeochromocytoma (n = 1). Eleven patients underwent adrenalectomy, but no cases of primary adrenal malignancy were observed. CONCLUSIONS: Patients with adrenal incidentaloma had a low risk of developing malignancy or hormonal hypersecretion during a short-term follow-up period.

- BACKGROUND:Hyperparathyroidism affects most patients with multiple endocrine neoplasia type 1 (MEN 1). This study investigates expression of the candidate MEN1 gene phospholipase C beta 3 (PLC beta 3) and expression and function of a putative calcium sensing protein (CAS) in hyperparathyroidism of MEN 1.METHODS:In 31 parathyroid glands from 17 patients with MEN 1, CAS distribution was studied immunohistochemically and parallel sections were explored for PLC beta 3 mRNA expression by in situ hybridization. Enzymatically dispersed parathyroid cells were analyzed for cytoplasmic calcium concentrations [Ca2+]i and parathyroid hormone (PTH) release.RESULTS:All glands exhibited a heterogeneously reduced CAS immunoreactivity, especially meager in nodularly assembled parathyroid cells. Calcium regulated [Ca2+]i and PTH release tended to be more deranged in the glands possessing the lowest immunostaining. Parathyroid PLC beta 3 invariably was homogeneously expressed, and this included even MEN 1 patients with reduced PLC beta 3 expression in endocrine pancreatic tumors.CONCLUSIONS:The findings support variable calcium insensitivity of [Ca2+]i and PTH release in hyperparathyroidism of MEN 1, apparently coupled to heterogeneously reduced CAS expression. For clarification of the role of PLC beta 3 in MEN 1 parathyroid tumorigenesis further study of this protein is required.

- BACKGROUND AND AIM: The aim of this study was to review the literature regarding the use of pre- and/or postoperative antibiotics in the management of appendicitis, using data obtained from PubMed and the Cochrane Library.MATERIAL AND METHODS: A literature search was conducted using the terms "appendicitis" combined with "antibiotics." Studies were selected based on relevance for the evidence on prophylactic and postoperative treatment with regard to the route and duration of drug administration and the findings of surgery.RESULTS: Patients with acute appendicitis should receive preoperative, broad-spectrum antibiotics. The use of postoperative antibiotics is only recommended in cases of perforation, and treatment should then be given intravenously, for a minimum period of 3-5 days for adult patients, until clinical signs such as fever resolve and laboratory parameters such as C-reactive protein curve and white blood cell (WBC) start to decline.CONCLUSION: Preoperative antibiotic prophylaxis is recommended in all patients with acute appendicitis, whereas postoperative antibiotics only in cases of perforation.

Binge eating and obesity treatment : prevalence, measurement and long-term outcome
- 2009
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Eating disorders and binge eating has repeatedly been shown to be common in surgical and behavioural weight loss treatments. Due to methodological variations and shortcomings in previous research, there is insufficient information about how eating disorders and binge eating are associated with outcome in weight loss treatments. There is therefore no consensus on how eating pathology should be adressed in weight loss treatments, which has led to large differences in the clinical practice. The main aim of this thesis was to address the issues of eating disorders and binge eating in weight loss treatments, and to investigate how binge eating is associated with long-term treatment outcome.

- Positron emission tomography (PET) supplies a range of labeled compounds to be used for the characterization of tumor biochemistry. Some of these have proved to be of value for clinical diagnosis, treatment follow up, and clinical research. The first routinely used PET tracer in oncology, 18F-labeled deoxyglucose (FDG), was successfully used for diagnosis of cancer, reflecting increased expression of glucose transporter in cancerous tissue. This tracer, however, usually does not show sufficient uptake in well-differentiated tumors such as neuroendocrine tumors. We developed a tracer more specific to neuroendocrine tumors—the serotonin precursor 5-hydroxytryptophan (5-HTP) labeled with 11C—and demonstrated increased uptake and irreversible trapping of this tracer in carcinoid tumors. The uptake was so selective and the resolution was so high that we could detect more liver and lymph node metastases with PET than with CT or octreotide scintigraphy. To further improve the method, especially to reduce the high renal excretion of the tracer producing streaky artifacts in the area of interest, we introduced premedication by the decarboxylase inhibitor carbidopa, leading to a six-fold decreased renal excretion while the tumor uptake increased three-fold, hence improving the visualization of the tumors.11C-labeled l-DOPA was evaluated as an alternative tracer, especially for endocrine pancreatic tumors, which usually do not demonstrate enhanced urinary serotonin metabolites. However, only half of the EPTs, mainly functioning tumors, could be detected with l-DOPA. Instead 5-HTP seems to be a universal tracer for EPT and foregut carcinoids. With new, more sensitive PET cameras, larger field of view and procedures for whole-body coverage, the PET examination with 5-HTP is now routinely performed as reduced whole-body PET examinations with coverage of the thorax and abdomen. With this method we have been able to visualize small neuroendocrine lesions in the pancreas and thorax (e.g., ACTH-producing bronchial carcinoids) not detectable by any other method, including octreotide scintigraphy, MRI, and CT. Another tracer, the 11β-hydroxylase inhibitor, metomidate labeled with 11C, was developed to simplify diagnosis and follow-up of patients with incidentalomas. A large series of patients with incidentally found adrenal masses have been investigated and so far all lesions of adrenocortical origin have been easily identified because of exceedingly high uptake of 11C-metomidate, whereas noncortical lesions showed very low uptake. In addition, adrenocortical cancer shows high uptake, suggesting that this PET tracer can be used for staging purposes.

- Dual-energy computed tomography (DECT) can acquire two datasets showing different attenuation levels allowing collectionof additional information about the elementary chemical compositionof the scanned material. Color can then be assigned accordingto the 80- and 140-kV computed tomography (CT) values to obtaina color-mapped, dual-energy image. DECT has been used extensivelyin our department in postmortem CT with excellent results (1).One of the advantages of DECT is that iodine contrast uptakein soft tissue can be quantified. We were wondering about itsability to localize parathyroid adenomas (PAs).

- Selective venous sampling (SVS) helps to interpret imaging results in patients with persistent primary hyperparathyroidism (pHPT). However, one of the drawbacks of conventional SVS may be low "spatial resolution", depending on the sample size. We modified SVS in the following way: first, patients underwent conventional SVS with up to 11 parathyroid hormone (PTH) samples taken. The quickPTH assay was used to measure PTH levels. The patients subsequently underwent super-selective venous sampling (super-SVS) in the region with the highest quickPTH level in the same session. The subjects were five consecutive patients with persistent pHPT investigated by various imaging techniques, none of which was considered conclusive. Therefore, all five patients underwent super-SVS, which was done successfully in four. Re-evaluation of the imaging results of these four patients resulted in localization of the parathyroid adenoma. Curative surgery was performed successfully in all four patients during the study period. Super-SVS increases the "spatial resolution" of conventional SVS and may have advantages when imaging results of patients with persistent pHPT are interpreted. Its true value must be analyzed in larger studies.

- Background. Operation and reoperation for hyperparathyroidism in multiple endocrine neoplasia type 1 (MEN 1) is controversial regarding surgical strategy, preoperative localization, and biochemical indexes of recurrence. Methods. Fifty patients with MEN 1 with hyperparathyroidism were followed up 2 to 27 years after subtotal (SPX; n = 35) or total parathyroidectomy with forearm autografiing (TPX; n = 15), including 24 who underwent 28 reoperations because of persistent or recurrent hyperparathyroidism. Results. Persistent or recurrent hyperparathyroidism was seen in 66% and 20% of patients after SPX involving extirpation of at least 3 glands and TPX, respectively, and 100% after single-gland excision as a primary procedure. After reoperation, hypercalcemia was reversed in 33% of patients by SPX and 61% by intended TPX procedures. All patients received vitamin D substitution after TPX, but restricted thyroid function allowed withdrawal in all but 10 patients (36%). Intact serum parathyroid hormone levels in nongrafted and grafted arms rose with time, but only exceptional ratios localized graft recurrence. Localization of recurrent hyperparathyroidism was achieved with 11 C-labeled methionine positron emission tomography. Conclusion. MEN 1 hyperparathyroidism has a high risk of recurrence, and operation may include primarily SPX of at least 3 glands or TPX, although the latter includes a higher risk of long-term hypoparathyroidism. Reoperation should involve TPX with recognition of the enhanced recurrence rate in individuals with postoperative hyperparathyroidism.

- Endocrine pancreatic tumors (EPTs) are rare but have a remarkably better prognosis than adenocarcinoma of the pancreas. Patients with EPTs benefit from surgical and medical therapy, which may alleviate symptoms due to hormonal excess and increase survival. Patients with large or malignant EPTs with infiltrative disease may suffer from local complications, including gastrointestinal bleeding and obstruction and involvement of the superior mesenteric (SMV) and portal (PV) veins. Among 31 patients with operable and large or malignant EPTs, 7 had hormone-producing syndromes (insulin, glucagon), and 24 had clinically nonfunctioning EPTs. Surgery in these patients included vascular reconstruction of the SMV/PV (n = 4), resection of infiltrated adjacent organs (n = 5; stomach, transverse colon), or resection of concomitant liver metastases (n = 3). Four patients with conspicuously large insulinomas, and three with glucagonoma were successfully operated on with alleviation of hormonal symptoms. Among the 24 nonfunctioning EPTs, 5 patients had been explored earlier and their tumors judged inoperable due to locally invasive disease or misdiagnosis as pancreatic adenocarcinoma. The operations were performed with no mortality and low morbidity. We conclude that large and malignant EPTs with limited spread of disease may benefit from a combination of medical and surgical therapy.

- We present here the complete primary structure of human gp330, the human variant of the principal kidney autoantigen causing Heymann membranous glomerulonephritis in rats. The deduced 4655 amino acid residues give a calculated molecular mass of 519636 Da for the mature protein and consists of a probable 25-amino-acid N-terminal signal peptide sequence, an extracellular region of 4398 amino acids, a single transmembrane-spanning domain of 23 amino acids, and an intracellular C-terminal region of 209 amino acid residues. Three types of cysteine-rich repeats characteristic of the low density lipoprotein receptor (LDLR) superfamily are present in human gp330. In the extracellular region, there are a total of 36 LDLR ligand-binding repeats, comprising four distinct domains, 16 growth factor repeats separated by eight YWTD spacer regions, and one epidermal growth factor-like repeat. No consensus cleavage sequence for the processing endoprotease furin is detected in human gp330. The intracellular tail contains not only two copies of the F(X)NPXY coated-pit mediated internalization signal characteristic of LDLR superfamily members, but also intriguing and potentially functional motifs including several Src-homology 3 recognition motifs, one Src-homology 2 recognition motif for the p85 regulatory subunit of phosphatidylinositol 3-kinase, and additional sites for protein kinase C, casein kinase II and cAMP-/cGMP-dependent protein kinase. There is approximately 77% amino acid identity between human and rat gp330 with minor differences between the extracellular and intracellular regions. Recently gp330 has been implicated in Ca2+ regulation in the parathyroid, the placenta, and the renal tubule, but its overall physiological and pathological role still remains uncertain.

Tidskriftsartikel (refereegranskat)abstract
- Background Adequate performance of trauma team activation (TTA) criteria is important in order to accurately triage trauma patients. The Swedish National Trauma Triage Criteria (SNTTC) consists of 29 criteria that trigger either a Trauma Alert, the highest level of TTA, or a Trauma Response. This study aimed to evaluate the SNTTC and its accuracy in predicting a severely injured patient in a multicenter setting. Methods A cohort study in Sweden involving six trauma receiving hospitals. Data was collected from the Swedish Trauma Registry. Some 626 patients were analyzed with regard to the specific criteria used to initiate the TTA, injury severity with New Injury Severity Score (NISS) and emergency interventions. Sensitivity, specificity, positive predictive value (PPV) and positive likelihood ratio (LR+) of the criteria were calculated, as well as undertriage and overtriage. Results All 29 criteria of SNTTC had a sensitivity > 80% for identifying a severely injured patient. The 16 Trauma Alert Criteria had a lower sensitivity of 62.6% but higher LR+ (3.5 vs all criteria 1.4), specificity (82.3 vs 39.1%) and PPV (55.4 vs 37.6%) and the highest accuracy (AUC 0.724). When using only the six physiological criteria, sensitivity (44.8%) and accuracy (AUC 0.690) decreased while LR+ (6.7), specificity (93.3%) and PPV (70.2%) improved. Conclusion SNTTC is efficient in identifying severely injured patients. The current set of criteria exhibits the best sensitivity compared to other examined combinations and no additional criterion was found to improve the protocol enough to promote a change.

- High nursing turnover and a shortage of nurses in acute hospital settings in Sweden challenge health care systems to deliver and ensure safe care. Advanced nursing roles implemented in other countries have offered nurses new career opportunities and had positive effects on patient safety, effectiveness of care, and patient satisfaction. The advanced nursing position of Nurse Practitioner has existed for many years in the United States, while similar extended nursing roles and changes in the scope of nursing practice are being developed in many other countries. In line with this international trend, the role of Nurse Practitioner in surgical care has been proposed for Sweden, and a master’s programme for Acute Nurse Practitioners has been in development for many years. To optimize and facilitate the introduction of this new nursing role and its supporting programme, we elicited the experiences and support of the group who developed a Nurse Practitioner programme for a university in the US. This paper describes this collaboration and sharing of experiences during the process of developing a Swedish Nurse Practitioner programme. We also discuss the challenges of implement- ting any new nursing role in any national health care system. We would like to share our collaborative experiences and thoughts for the future and to open further national and international dialogue about how best to expand the scope of practice for nurses in acute hospital care, and thereby to improve patient care in Sweden and elsewhere.
