- Background: In women with rheumatoid arthritis (RA) it has been observed that during pregnancy a majority of patients experience amelioration, but after delivery a relapse of the disease is common. However, there are few studies, with diverging results, addressing the effect of parity on the severity of RA over time. Our aim was to explore the impact of parity, with stratification for anti-citrullinated protein antibody (ACPA) status as well as for onset during reproductive age or not. Methods: Female RA cases aged 18-70 years were recruited for the Epidemiological Investigation of Rheumatoid Arthritis (EIRA). Information on disease severity (the health assessment questionnaire (HAQ) and the disease activity score 28 (DAS28)) was retrieved from the Swedish Rheumatology Quality Register at inclusion and 3, 6, 12 and 24 months after diagnosis. Mixed models were used to compare mean DAS28 and HAQ scores over time in parous and nulliparous women. Mean differences at individual follow-up visits were compared using analysis of covariance. The odds of having DAS28 or HAQ above the median in parous verus nulliparous women were estimated in logistic regression models. Results: A total of 1237 female cases (mean age 51 years, 65 % ACPA-positive) were included. ACPA-negative parous women, aged 18-44 years, had on average 1.17 units higher DAS28 (p < 0.001) and 0.43 units higher HAQ score (p < 0.001) compared to nulliparous women during the follow-up time, adjusted for age. In this subgroup, the average DAS28 and HAQ scores were significantly higher in parous women at all follow-up time points. Younger parous ACPA-negative women were significantly more likely to have DAS28 and HAQ values above the median compared to nulliparous women at all follow-up visits. No association between parity and severity of ACPA-positive disease was observed. Conclusions: Parity was a predictor of a more severe RA among ACPA-negative younger women, which might indicate that immunomodulatory changes during and after pregnancy affect RA severity, in particular for the ACPA-negative RA phenotype.

Research review (peer-reviewed)abstract
- Safe and reliable venous access is mandatory in modern health care, but central venous catheters (CVCs) are associated with significant morbidity and mortality, This paper describes current Swedish guidelines for clinical management of CVCs The guidelines supply updated recommendations that may be useful in other countries as well. Literature retrieval in the Cochrane and Pubmed databases, of papers written in English or Swedish and pertaining to CVC management, was done by members of a task force of the Swedish Society of Anaesthesiology and Intensive Care Medicine. Consensus meetings were held throughout the review process to allow all parts of the guidelines to be embraced by all contributors. All of the content was carefully scored according to criteria by the Oxford Centre for Evidence-Based Medicine. We aimed at producing useful and reliable guidelines on bleeding diathesis, vascular approach, ultrasonic guidance, catheter tip positioning, prevention and management of associated trauma and infection, and specific training and follow-up. A structured patient history focused on bleeding should be taken prior to insertion of a CVCs. The right internal jugular vein should primarily be chosen for insertion of a wide-bore CVC. Catheter tip positioning in the right atrium or lower third of the superior caval vein should be verified for long-term use. Ultrasonic guidance should be used for catheterisation by the internal jugular or femoral veins and may also be used for insertion via the subclavian veins or the veins of the upper limb. The operator inserting a CVC should wear cap, mask, and sterile gown and gloves. For long-term intravenous access, tunnelled CVC or subcutaneous venous ports are preferred. Intravenous position of the catheter tip should be verified by clinical or radiological methods after insertion and before each use. Simulator-assisted training of CVC insertion should precede bedside training in patients. Units inserting and managing CVC should have quality assertion programmes for implementation and follow-up of routines, teaching, training and clinical outcome. Clinical guidelines on a wide range of relevant topics have been introduced, based on extensive literature retrieval, to facilitate effective and safe management of CVCs.

Journal article (peer-reviewed)abstract
- BACKGROUND: Higher operative risks after pneumonectomy for non-small cell lung cancer (NSCLC) have been reported after neoadjuvant chemotherapy or radiotherapy, or both. Patients who underwent pneumonectomy for NSCLC were evaluated for effect of neoadjuvant treatment on mortality and morbidity, especially bronchopleural fistula. METHODS: Between 1996 and 2003, 130 consecutive patients underwent pneumonectomy: 35 received preoperative radiotherapy and chemotherapy (the neoadjuvant group), and 95 patients did not (the first-surgery group). Operative mortality and postoperative complications were compared between the groups. RESULTS: Minor postoperative complications were comparable in both groups (p > 0.10). Five patients in the neoadjuvant group and 10 in the first-surgery group had serious complications (p = 0.55). Eight had bronchopleural fistulas (7 right and 1 left, p < 0.01); 3 were in the neoadjuvant group (p = 0.49). Three fistulas required reoperation. One patient in the first-surgery group died within 30 days postoperatively. Duration of symptoms (hazard ratio, 6.6; p = 0.01) and right-sided pneumonectomy (hazard ratio, 2.4; p = 0.05) were associated with an increased risk of bronchopleural fistula. Induction treatment, postoperative radiotherapy, or coverage of the bronchial stump did not increase the risk of bronchopleural fistulation. Survival at 1 and 5 years was comparable for the neoadjuvant and first-surgery groups: 74% and 46% vs 72% and 34%, respectively (p > 0.2). CONCLUSIONS: Pneumonectomy is a safe procedure with low operative mortality. Postoperative morbidity is significant, especially bronchopleural fistulas after right-sided pneumonectomy (11%). However, neither operative mortality nor morbidity appears to be directly associated with preoperative radiotherapy or chemotherapy.

Impact of resuscitation fluid bag size availability on volume of fluid administration in the intensive care unit
- 2018
-
In: Acta Anaesthesiologica Scandinavica. - : Wiley. - 0001-5172 .- 1399-6576. ; 62:9, s. 1261-1266
-
Journal article (peer-reviewed)abstract
- BACKGROUND: Iatrogenic fluid overload is associated with increased mortality in the intensive care unit (ICU). Decisions on fluid therapy may, at times, be based on other factors than physiological endpoints. We hypothesized that because of psychological factors volume of available fluid bags would affect the amount of resuscitation fluid administered to ICU patients.METHODS: We performed a prospective intervention cross-over study at 3 Swedish ICUs by replacing the standard resuscitation fluid bag of Ringer's Acetate 1000 mL with 500 mL bags (intervention group) for 5 separate months and then compared it with the standard bag size for 5 months (control group). Primary endpoint was the amount of Ringer's Acetate per patient during ICU stay. Secondary endpoints were differences between the groups in cumulative fluid balance and change in body weight, hemoglobin and creatinine levels, urine output, acute kidney failure (measured as the need for renal replacement therapy, RRT) and 90-day mortality.RESULTS: Six hundred and thirty-five ICU patients were included (291 in the intervention group, 344 in the control group). There was no difference in the amount of resuscitation fluid per patient during the ICU stay (2200 mL [1000-4500 median IQR] vs 2245 mL [1000-5630 median IQR]), RRT rate (11 vs 9%), 90-day mortality (11 vs 10%) or total fluid balance between the groups. The daily amount of Ringer's acetate administered per day was lower in the intervention group (1040 (280-2000) vs 1520 (460-3000) mL; P = .03).CONCLUSIONS: The amount of resuscitation fluid administered to ICU patients was not affected by the size of the available fluid bags. However, altering fluid bag size could have influenced fluid prescription behavior.

Journal article (peer-reviewed)abstract
- Abstract OBJECTIVES: To identify risk factors for reoperation following surgery for spontaneous pneumothorax. MATERIALS AND METHODS: This is a retrospective clinical study conducted on 240 consecutive patients operated on for spontaneous pneumothorax in Lund University Hospital between January 1996 and December 2003. Patient information was gained from medical charts and operation reports. Logistic regression analysis was used to evaluate risk factors. Median follow-up was 54 months. RESULTS: Video-assisted thoracoscopic surgery (VATS) was used in 93% of the patients, where bullectomy with or without pleurodesis/pleurectomy was performed in most cases. Conversion to anterolateral thoracotomy was required in 6 cases (2.3%). Operative mortality (<30 days) was 0.8% (0% after VATS). Altogether 35 patients (13.7%) required a reoperation. Twenty patients were reoperated on within one month from surgery, most often due to prolonged air leakage (n=13, 5.1%) and bleeding (n=6, 2.3%). Fifteen patients (5.8%) were reoperated on because of recurrent pneumothorax, on average 17 months (range 1-39 months) after the primary operation. Significant independent risk factors for reoperation were; young age, operations performed for secondary pneumothorax due to emphysema and recurrent pneumothorax. The risk was also increased in patients where wedge resection was not performed. However, the type of pleurodesis or pleurectomy was not related to increased risk. CONCLUSIONS: A considerable number of patients require reoperation after VATS for pneumothorax. Most reoperations are due to prolonged air leakage or recurrent pneumothorax. The risk for reoperation is increased in younger patients, patients operated for recurrent or secondary pneumothorax, and in cases where pulmonary wedge resection is not performed.

Morning conferences for anaesthesiologists - to be or not to be?
- 2013
-
In: Acta Anaesthesiologica Scandinavica. - : Wiley. - 0001-5172. ; 57:8, s. 971-977
-
Journal article (peer-reviewed)abstract
- BACKGROUND: The main objectives of this study were to clarify the contents of and attitudes to morning conferences for physicians at Swedish departments of anaesthesiology and intensive care medicine. METHODS: A prospective cross-sectional three-part study was carried out. Heads of departments responded to a national survey on the structure and content of morning conferences. A questionnaire on attitudes to and general contents of morning conferences was filled out by anaesthesiologists in the Scania region in southern Sweden. Furthermore, telephone interviews were made with anaesthesiologists on primary night call in the Scania region to obtain information on whether their needs to report had been met and on how the conferences had actually been carried out and attended by the physicians. RESULTS: Information was obtained from 52 departmental heads (80%), 113 anaesthesiologists (53%), and 83 physicians on primary call (92%). Issues most frequently brought up were reports from physicians on night call, discussions of clinical matters, issues of staffing, and organizational matters. Daily morning conferences were strongly favoured for intercollegial solidarity and contacts, and were mainly and regularly used for reports from physicians on night call. At 95% of them, physicians on night call considered themselves to have been allowed to report what they wanted or needed to. CONCLUSIONS: Daily morning conferences enable regular exchange of information and professional experience, and are considered by Swedish anaesthesiologists to be most valuable for intercollegial solidarity and contacts. Before changes are being made in frequency or duration of morning conferences, their actual structure and content should be carefully evaluated and critically challenged to fit specific needs of that individual department.

Total-tau and neurofilament light in CSF reflect spinal cord ischaemia after endovascular aortic repair
- 2016
-
In: Neurochemistry International. - : Elsevier BV. - 0197-0186 .- 1872-9754. ; 93, s. 1-5
-
Journal article (peer-reviewed)abstract
- BACKGROUND: Repair of extensive aortic disease may be associated with spinal cord ischaemia (SCI). Here we test if levels of cerebrospinal fluid (CSF) biomarkers for neuronal injury are altered in patients with SCI after advanced endovascular repair of extensive aortic disease.METHODS: CSF was sampled for up to 48 hours in ten patients undergoing endovascular aortic repair and analyzed for the axonal damage markers total-tau (T-tau) and neurofilament light (NFL).RESULTS: Six of ten patients developed SCI (clinically present within 3-6 hours). CSF levels of NFL increased up to 37-fold in patients with, but were stable in patients without, SCI. CSF levels of T-tau also increased in patients with SCI, but with some overlap with patients without SCI. Levels of NFL and T-tau did not increase until after the appearance of neurological symptoms (12-48 h after aortic repair).CONCLUSIONS: The CSF biomarkers NFL and T-tau both reflect development of SCI after endovascular aortic repair, but do not rise until after clinical signs of SCI appear. Future studies are desirable to identify earlier biomarkers of SCI.

Journal article (peer-reviewed)abstract
- BACKGROUND: Fluid overload in ICU patients is associated with increased morbidity and mortality. Although studies report on optimisation of resuscitation fluids given to ICU patients, increasing evidence suggests that maintenance fluids and fluids used to administer drugs are important sources of fluid overload.OBJECTIVES: We aimed to evaluate the volume of maintenance fluids and electrolytes on overall fluid balance and their relation to mortality in stabilised ICU patients.DESIGN: Multicentre retrospective observational study.SETTING: Six mixed surgical and medical ICUs in Sweden.PATIENTS: A total of 241 adult patients who spent at least 7 days in the ICU during 2018.MAIN OUTCOME MEASURES: The primary endpoint was the volume of maintenance, resuscitation and drug diluent fluids administered on days 3 to 7 in the ICU. Secondary endpoints were to compare dispensed amounts of maintenance fluids and electrolytes with predicted requirements. We also investigated the effects of administered fluids and electrolytes on patient outcomes.RESULTS: During ICU days 3 to 7, 56.4% of the total fluids given were maintenance fluids, nutritional fluids or both, 25.4% were drug fluids and 18.1% were resuscitation fluids. Patients received fluids 1.29 (95% confidence interval 1.07 to 1.56) times their estimated fluid needs. Despite this, 93% of the cohort was treated with diuretics or renal replacement therapy. Patients were given 2.17 (1.57 to 2.96) times their theoretical sodium needs and 1.22 (0.75 to 1.77) times their potassium needs. The median [IQR] volume of fluid loss during the 5-day study period was 3742 [3156 to 4479] ml day-1, with urine output the main source of fluid loss. Death at 90 days was not associated with fluid or electrolyte balance in this cohort.CONCLUSION: Maintenance and drug fluids far exceeded resuscitative fluids in ICU patients beyond the resuscitative phase. This excess fluid intake, in conjunction with high urinary output and treatment for fluid offload in almost all patients, suggests that a large volume of the maintenance fluids given was unnecessary.TRIAL REGISTRATION: ClinicalTrials.org (identifier: NCT03972475).
