- Background: Most commonly used outcome measures in peripheral arterial disease (PAD) provide scarce information about achieved patient benefit. Therefore, patient-reported outcome measures have become increasingly important as complementary outcome measures. The abundance of items in most health-related quality of life instruments makes everyday clinical use difficult. This study aimed to develop a short version of the 25-item Vascular Quality of Life Questionnaire (VascuQoL-25), a PAD-specific health-related quality of life instrument. Methods: The study recruited 129 individuals with intermittent claudication and 71 with critical limb ischemia from two university hospitals. Participants were a mean age of 70 +/- 9 years, and 57% were men. All patients completed the original VascuQoL when evaluated for treatment, and 127 also completed the questionnaire 6 months after a vascular procedure. The VascuQoL-25 was reduced based on cognitive interviews and psychometric testing. The short instrument, the VascuQoL-6, was tested using item-response theory, exploring structure, precision, item fit, and targeting. A subgroup of 21 individuals with intermittent claudication was also tested correlating the results of VascuQoL-6 to the actual walking capacity, as measured using global positioning system technology. Results: On the basis of structured psychometric testing, the six most informative items were selected (VascuQoL-6) and tested vs the original VascuQoL-25. The correlation between VascuQoL-25 and VascuQoL-6 was r = 0.88 before intervention, r = 0.96 after intervention, and the difference was r = 0.91 (P < .001). The Cronbach alpha for the VascuQoL-6 was .85 before and .94 after intervention. Cognitive interviews indicated that the responders considered all six items to be relevant and comprehensible. Rasch analysis was used to reduce response options from seven (VascuQoL-25) to four (VascuQoL-6). VascuQol-6 was shown to have high precision and discriminative properties. Item fit was excellent, with both "infit" and "outfit" between 0.7 and 1.3 for all six items. The standardized response mean after intervention was 1.15, indicating good responsiveness to clinical change. VascuQoL-6 results correlated strongly (r = 0.72; P < .001) with the actual measured walking ability (n = 21). Conclusions: VascuQoL-6 is a valid and responsive instrument for the assessment of health-related quality of life in PAD. The main advantage is the compact format that offers a possibility for routine use in busy clinical settings.

- Our aim was to evaluate the treatment given to patients with intraosseus ameloblastomas with special emphasis on recurrence and the outcomes of primary and secondary resection. Forty-eight patients who were treated for intraosseous ameloblastoma at 8 centres across Sweden met the inclusion criteria. They showed typical distribution of age, sex, site of lesion, and characteristic presenting features. Eleven of the 48 were initially treated with radical resection and none recurred. Twenty-two of the remaining 37 who were initially treated by conservative resection presented with recurrences. Sixteen of the 22 then had conservative secondary resections, which resulted in further recurrence in 6 patients. Initial radical resection is therefore superior to conservative management as far as recurrences are concerned. We argue, however, that a conservative surgical approach is adequate for many intraosseous ameloblastomas with limited extension, because relapse can be followed by radical resection if clinically indicated in selected cases.

Starting a Swedish national quality registry for orthognathic surgery: a tool for auditing fundamentals of care
- 2022

Tidskriftsartikel (refereegranskat)abstract
- Background: National quality registries (NQRs) provide open data for user-directed acquisition. National Quality Registry (NQR) data are often used to analyze the rates of treatment success and adverse events for studies that aim to improve treatment quality and patient satisfaction. Thus, NQRs promote the goal of achieving evidence-based therapies. However, the scientific literature seldom focuses on the complex process of initiating, designing, and implementing an NQR. Starting an NQR may be particularly challenging in a setting where specialized care is decentralized, such as orthognathic surgery in Sweden. The present study describes the initiation and early phases of a new NQR for orthognathic surgery in Sweden. Methods: The initial inventory phase included gaining knowledge on regulations, creating economic plans, and identifying pitfalls in existing NQRs. Next, a crude framework for the registry was achieved. Outcome measures were selected with a nation-wide questionnaire, followed by a Delphi-like process for selecting parameters to include in the NQR. Our inclusive process comprised a stepwise introduction, feedback-based modifications, and preparatory educational efforts. Descriptive data were collected, based on the first 2 years (2018–2019) of registry operation. Results: Two years after implementation, 862 patients that underwent 1320 procedures were registered. This number corresponded to a 91% coverage rate. Bimaxillary treatments predominated, and the most common were a Le Fort I osteotomy combined with a bilateral sagittal split osteotomy (n = 275). Reoperations were conducted in 32 patients (3.6%), and the rate of patient satisfaction was 95%. Conclusions: A National Quality Registry should preferentially be started and maintained by an appointed task force of active clinicians. A collaborative, transparent, inclusive process may be an important factor for achieving credibility and high coverage, particularly in a decentralized setting.

- The aim of this meta-analysis was to test the null hypothesis of no difference in the implant failure rates, marginal bone loss (MBL)and post-operative infection for patients being rehabilitated by turned versus anodised-surface implants, against the alternative hypothesis of a difference. An electronic search without time or language restrictions was undertaken in November 2015. Eligibility criteria included clinical human studies, either randomised or not. Thirty-eight publications were included. The results suggest a risk ratio of 2·82 (95% CI 1·95–4·06, P < 0·00001) for failure of turned implants, when compared to anodised-surface implants. Sensitivity analyses showed similar results when only the studies inserting implants in maxillae or mandibles were pooled. There were no statistically significant effects of turned implants on the MBL (mean difference-MD 0·02, 95%CI −0·16–0·20; P = 0·82) in comparison to anodised implants. The results of a meta-regression considering the follow-up period as a covariate suggested an increase of the MD with the increase in the follow-up time (MD increase 0·012 mm year−1), however, without a statistical significance (P = 0·813). Due to lack of satisfactory information, meta-analysis for the outcome ‘post-operative infection’ was not performed. The results have to be interpreted with caution due to the presence of several confounding factors in the included studies. © 2016 John Wiley & Sons Ltd

- Neuropathic pain conditions are common after nerve injuries and are suggested to be regulated in part by genetic factors. We have previously demonstrated a strong genetic influence of the rat major histocompatibility complex on development of neuropathic pain behavior after peripheral nerve injury. In order to study if the corresponding human leukocyte antigen complex (HLA) also influences susceptibility to pain, we performed an association study in patients that had undergone surgery for inguinal hernia (n = 189). One group had developed a chronic pain state following the surgical procedure, while the control group had undergone the same type of operation, without any persistent pain. HLA DRB1genotyping revealed a significantly increased proportion of patients in the pain group carrying DRB1*04 compared to patients in the pain-free group. Additional typing of the DQB1 gene further strengthened the association; carriers of the DQB1*03:02 allele together with DRB1*04 displayed an increased risk of postsurgery pain with an odds risk of 3.16 (1.61-6.22) compared to noncarriers. This finding was subsequently replicated in the clinical material of patients with lumbar disc herniation (n = 258), where carriers of the DQB1*03:02 allele displayed a slower recovery and increased pain. In conclusion, we here for the first time demonstrate that there is an HLA-dependent risk of developing pain after surgery or lumbar disc herniation; mediated by the DRB1*04 - DQB1*03:02 haplotype. Further experimental and clinical studies are needed to fine-map the HLA effect and to address underlying mechanisms.

Tidskriftsartikel (refereegranskat)abstract
- BackgroundIn most cases, a combination of paracetamol and ibuprofen are the optimal treatment for postoperative pain in third molar surgery. If stronger analgesia is required, opioids are traditionally administered. In day-case, surgery; however, opioids should be avoided. Thus, the anaesthetic agent S-ketamine in analgesic doses might be preferred.MethodsThe study was designed as a randomized placebo-controlled double-blind clinical trial. The study enrolled healthy subjects according to the American Society of Anaesthesiologists classification; I or II (ASA), aged 18 to 44 years, with a body weight between 50 and 100 kg. The patients were randomized into three groups where two doses of S-ketamine were compared (high: 0.25 mg/kg or low: 0.125 mg/kg) with placebo (saline).ResultsA primary outcome of the study was that VAS at 4 h postoperatively, showed no significant difference between the placebo and high-dose S-ketamine group or in the low-dose group. We found a significant difference between the groups for the first 24 h, with a lower VAS-score in the high-dose S-ketamine group. The time to when 50% had taken their first rescue medication was 12 min later in the high-dose ketamine group.ConclusionsPre-emptive S-ketamine 0.25 mg/kg gave a global significant reduction of pain by VAS during the first 24 h postoperatively. The time from end of surgery to first rescue medication were longer in the high-dose ketamine group compared to both low-dose ketamine and placebo groups.

- Hip fractures are a major cause of hospital stay among the elderly, and result in increased disability and mortality. In this study from 1 April 2003 to 31 March 2004, the influence of optimised treatment of hip fracture on time to operation, length of hospital stay, reoperations and mortality within 1 year were investigated. Comparisons were made between the first 210 patients in the period and the last 210 patients, who followed the new clinical pathway introduced at the University Hospital in Lund, Sweden. Early surgery, within 24h, was not associated with reduced mortality, but was significantly associated with reduced length of stay (p<0.001). Significantly more cases of osteosynthesis for femoral neck fracture were reoperated compared with all other types of surgery (p<0.001) when reoperations with extraction of the hook pins in healed fractures were excluded. Mortality was significantly higher among men than women at 4 (p=0.025) and 12 (p=0.001) months after fracture and among medically fit patients with administrative delay to surgery compared with patients with no delay (p<0.001).

- Introduction and hypothesis: Urinary incontinence (UI) is common among the elderly, but the literature is sparse on the surgical treatment of UI among the elderly. This systematic review aims to assess the effectiveness of surgical interventions as treatment for urinary incontinence in the elderly population ≥65 years of age.Methods: Randomized controlled trials (RCT) and prospective nonrandomized studies (NRS) were included. The databases PubMed (NLM), EMBASE (Elsevier), Cochrane Library (Wiley), and Cinahl (EBSCO) were searched for the period 1966 up to October 2013. The population had to be ≥65 years of age and had to have undergone urethral sling procedures, periurethral injection of bulking agents, artificial urinary sphincter surgery, bladder injection treatment with onabotulinumtoxin A or sacral neuromodulation treatment. Eligible outcomes were episodes of incontinence/urine leakage, adverse events, and quality of life.The studies included had to be at a moderate or low risk of bias. Mean difference (MD) or standard mean difference (SMD)as well as risk difference (RD) and the 95 % CI were calculated.Results: Five studies-all on the suburethral sling procedure in women- that fulfilled the inclusion criteria were identified. The proportion of patients reporting persistent SUI after surgery ranged from 5.2 to 17.6 %. One study evaluating quality of life (QoL) showed a significant improvement after surgery. The complication rates varied between 1 and 26 %, mainly bladder perforation, bladder emptying disturbances, and de novo urge.Conclusion: The suburethral sling procedure improves continence as well as QoL among elderly women with SUI; however, evidence is limited.

Ingår i: SAGE Open Medicine. - : Sage Publications. - 2050-3121. ; 7, s. 1-7
-
Tidskriftsartikel (refereegranskat)abstract
- Objectives: The aim of this study was to establish the top 10 research uncertainties in aortic dissection together with the patient organization Aortic Dissection Association Scandinavia using the James Lind Alliance concept. Methods: A pilot survey aiming to identify uncertainties sent to 12 patients was found to have high content validity (scale content validity index = 0.91). An online version of the survey was thereafter sent to 30 patients in Aortic Dissection Association Scandinavia and 45 caregivers in the field of aortic dissection. Research uncertainties of aortic dissection were gathered, collated and processed. Results: Together with research priorities retrieved from five different current guidelines, 94 uncertainties were expressed. A shortlist of 24 uncertainties remained after processing for the final workshop. After the priority-setting process, using facilitated group format technique, the ranked final top 10 research uncertainties included diagnostic tests for aortic dissection; patient information and care continuity; quality of life; endovascular and medical treatment; surgical complications; rehabilitation; psychological consequences; self-care; and how to improve prognosis. Conclusion: These ranked top 10 important research priorities may be used to justify specific research in aortic dissection and to inform healthcare research funding decisions.

Systemic betamethasone accelerates functional recovery after a crush injury to rat sciatic nerve
- 2005
-

Tidskriftsartikel (refereegranskat)abstract
- Purpose: The aim of the study was to evaluate the effect of perioperatively systemically administered betamethasone on nerve recovery (within or outside a confined space) after induced nerve crush injury. Materials and Methods: The sciatic nerve of 40 adult Wistar rats was crushed. In half of the animals, the injured nerve was entrapped in a silicone tube to simulate the environment of a closed space, and in the other half the nerve was left to heal. Half of the rats in each group were treated with subcutaneous betamethasone (2 mg/kg body weight/day) during the first 24 hours, starting preoperatively, whereas the other half, the control animals, were given the same amount of physiological saline. All animals underwent preoperative and postoperative walking track analysis (toe spread [TS] and intermediate toe spread [ITS]) twice weekly for 6 weeks. Results: For nonconfined space groups, there was no significant difference between the 2 groups (P=.052 for ITS and P =.315 for TS) during the first 2 weeks. Starting from the end of the second week, animals treated with betamethasone recovered more rapidly than did the controls (P <.001) and continued to do so until the end of the observation period. In the confined space groups, there was a significant difference between the 2 groups for ITS (P <.001) and for TS (P <.05) during the first 2 weeks. The difference continued at almost the same level of significance (P =.001) for ITS, whereas for TS, the difference disappeared after the second week. Conclusions: We conclude that short-term perioperative administration of betamethasone has a beneficial effect on the recovery of the injured rat sciatic nerve.
