- Background: Fundoplication is an essential step in para-oesophageal hernia (POH) repair, but which type minimizes postoperative mechanical complications is controversial.Methods: This was a randomized, double-blind clinical trial conducted between May 2009 and October 2018. Patients with symptomatic POH were allocated to either a total (Nissen) or a posterior partial (Toupet) fundoplication after hernia reduction and crural repair. The primary outcome was dysphagia (Ogilvie dysphagia scores) at 6 months postoperatively. Secondary outcomes were peri- and postoperative complications, swallowing difficulties assessed by the Dakkak dysphagia score, gastro-oesophageal reflux, quality of life (QoL), and radiologically confirmed hernia recurrence.Results: A total of 70 patients were randomized to a Nissen (n = 32) or a Toupet (n = 38) fundoplication. Compared with baseline, Ogilvie dysphagia scores were stable at the 3- and 6-month follow-up in the Nissen group (P = 0.075 and 0.084 respectively) but significantly improved in the Toupet group (from baseline mean (s.d.): 1.4 (1.1) to 0.5 (0.8) at 3 months, and 0.5 (0.6) at 6 months; P= 0.003 and P = 0.001 respectively). At 6 months, Dakkak dysphagia scores were significantly higher in the Nissen group than in the Toupet group (mean (s.d.): 10.4 (7.9) versus 5.1(7.2); P = 0.003). QoL scores improved throughout the follow-up. However, at 3 and 6 months postoperatively, the absolute median improvement (A) from preoperative values in the mental component scores of the Short Form-36 QoL questionnaire was significantly higher in the Toupet group (median (i.q.r.): 7.1 (-0.6 to 15.2) versus 1.0 (-5.4 to 3.3) at 3 months, and 11.2 (1.4 to 18.3) versus 0.4 (-9.4 to 7.5) at 6 months; (P =0.010 and 0.003 respectively)). At 6 months, radiologically confirmed POH recurrence occurred in 11 of 24 patients (46 per cent) of the Nissen group and in 15 of 32 patients (47 per cent) of the Toupet group (P = 1.001).Conclusions: A partial posterior wrap (Toupet fundoplication) showed reduced obstructive complications and improved QoL compared with a total (Nissen) fundoplication following POH repair.

Tidskriftsartikel (refereegranskat)abstract
- Background: We have previously performed a genome-wide linkage study in Scandinavian Type 1 diabetes (T1D) families. In the Swedish families, we detected suggestive linkage (LOD less than= 2.2) to the chromosome 5p13-q13 region. The aim of our study was to investigate the linked region in search for possible T1D susceptibility genes. Methodology/Principal Findings: Microsatellites were genotyped in the Scandinavian families to fine-map the previously linked region. Further, SNPs were genotyped in Swedish and Danish families as well as Swedish sporadic cases. In the Swedish families we detected genome-wide significant linkage to the 5-hydroxytryptamine receptor 1A (HTR1A) gene (LOD 3.98, pless than9.8x10(-6)). Markers tagging two separate genes; the ring finger protein 180 (RNF180) and HTR1A showed association to T1D in the Swedish and Danish families (pless than0.002, pless than0.001 respectively). The association was not confirmed in sporadic cases. Conditional analysis indicates that the primary association was to HTR1A. Quantitative PCR show that transcripts of both HTR1A and RNF180 are present in human islets of Langerhans. Moreover, immunohistochemical analysis confirmed the presence of the 5-HTR1A protein in isolated human islets of Langerhans as well as in sections of human pancreas. Conclusions: We have identified and confirmed the association of both HTR1A and RFN180, two genes in high linkage disequilibrium (LD) to T1D in two separate family materials. As both HTR1A and RFN180 were expressed at the mRNA level and HTR1A as protein in human islets of Langerhans, we suggest that HTR1A may affect T1D susceptibility by modulating the initial autoimmune attack or either islet regeneration, insulin release, or both.

- Background: The aim of this study is to report the short-term results of catheter-directed foam sclerotherapy (CDFS) in the treatment of axial saphenous vein incompetence. Patients and methods: Data of all patients undergoing CDFS for symptomatic primary incompetence of the great or small saphenous vein were prospectively collected. Treatment results in terms of occlusion rate and patients grade of satisfaction were analysed. All successfully treated patients underwent clinical and duplex follow-up examinations one year postoperatively. Results: Between September 2006 and September 2010, 357 limbs (337 patients) were treated with CDFS at our institution. Based on the CEAP classification, 64 were allocated to clinical class C3 , 128 to class C4, 102 to class C5 and 63 to class C6. Of the 188 patients who completed the one year follow up examination, 67 % had a complete and 14 % a near complete obliteration of the treated vessel. An ulcer-healing rate of 54 % was detected. 92 % of the patients were satisfied with the results of treatment. We registered six cases of thrombophlebitis and two cases of venous thromboembolism, all requiring treatment. Conclusions: The short-term results of CDFS in patients with axial vein incompetence are acceptable in terms of occlusion and complications rates.

- Patients with critical limb ischemia (CLI) have a high frequency of concomitant coronary heart disease and congestive heart failure. The aim of the study was to evaluate cardiac function in relation to inflammatory markers and 1-year mortality rate among patients with CLI. The authors investigated 232 consecutive patients with CLI by means of electrocardiogram (ECG), and measurements of endothelin (ET)-1, tumor necrosis factor alpha (TNF)a, interleukin (IL)-6, neopterin, CD40 ligand, and 8-epi-prostaglandin (PG)F2a in plasma. Echocardiography (echo) was performed in 88 (38%) patients. One-year mortality rate was assessed after prospective follow-up. One hundred and eighty-six (80%) patients had sinus rhythm (SR), 36 (16%) had atrial fibrillation or flutter (AF), and 10 (4%) pacemaker rhythm. Ischemic ECG changes occurred in 143 (62%) patients. Patients with AF showed higher IL-6 (p=0.0296) and neopterin (p=0.0494) concentrations. Patients with ischemic ECG changes showed higher ET-1 (p=0.0303), 8-epi-PGF2a (p=0.0027), neopterin (p=0.0004) concentrations and 1-year mortality rate (p=0.0105). The difference in ET-1 remained in logistic regression (p=0.0152). Internal diameter of the left ventricle on echo correlated with IL-6 (r =0.345, p=0.0017), TNFa (r =0.240, p=0.0273), and neopterin (r =0.327, p=0.0028). Internal diameter of the left atrium correlated with TNFa (r =0.384, p=0.0092) and neopterin (r =0.526, p=0.0004), and ejection fraction (EF) correlated inversely with IL-6 (r =-0.380, p=0.0015) and neopterin (r =-0.346, p=0.0038). Patients with EF <40% showed higher (p=0.0462) 1-year mortality rate than patients with EF >40%. In conclusion, in critical limb ischemia, cardiac rhythm disturbances and ischemic ECG changes were related to inflammatory mediators and predicted 1-year mortality rate. The inflammatory mediators correlated with echocardiographic signs of congestive heart failure.

- OBJECTIVE: to evaluate platelet and leukocyte activation during aortoiliac angiography and percutaneous transluminal angioplasty (PTA). METHODS: an observational study of 14 patients with aortoiliac atherosclerotic disease, nine of whom underwent PTA. The proportion of fibrinogen-, and P-selectin positive platelets, P-selectin expression on platelets, intraplatelet cGMP and cAMP, CD18 positive granulocytes, CD18 expression on granulocytes, plasma (p)-neopterin, p-TNF alpha and p- interleukin-6 were repeatedly measured in arterial blood during angiography and in venous blood before and after. RESULTS: compared to a previous venous sample, arterial intraplatelet cAMP was increased proximal to the atherosclerotic lesion before contrast infusion and PTA (median 18 [range: 14-22] vs 16 [15-21] pmol/10(9) platelets p<0.05), and intraplatelet cGMP was increased proximal to the lesion after contrast infusion and PTA (1.2 [0.8-3.9] vs 0.9 [0.6-2.5] pmol/10(9) platelets p<0.05). Four hours after angiography, both the proportion of P-selectin positive platelets (28[11-55]%) and platelet P-selectin expression (9[6-40]) had decreased (p<0.05), from arterial values distal to the lesion before contrast infusion and PTA (57 [24-78]% and 26 [10-83]). Granulocyte CD18 expression was lower during angiography than in a previous venous sample. CONCLUSIONS: the results are compatible with platelet but not leukocyte activation during peripheral angiography.

- Objective. To explore how malocclusions affect daily life in adolescents and how adolescents cope with malocclusion-related distress. Materials and methods. Twelve strategically selected teenagers, seven girls and five boys aged 13-14 years, participated in this study. Open, tape-recorded in-depth interviews based on Focus Group Discussions (FGD) were performed using a theme guide and analyzed according to the qualitative method of classic grounded theory (GT). Results. A core category was identified and named 'Repeatedly reminded of the malocclusion'. Associated to the core category, five categories were generated and labeled 'Being directed by the media's ideal image', 'Monitoring others' teeth', 'Struggling with low self-esteem', 'Hiding one's teeth' and 'Striving for cure'. Low self-esteem appeared to be frequently reinforced through the concerns for the malocclusion and handled via different coping strategies, such as hiding the teeth and striving to receive orthodontic treatment. Such processes were further enforced through the influence of media. Low self-esteem could be associated to a visible malposition of teeth, according to the informants. Having to wait for orthodontic treatment was frustrating the adolescents. Conclusions. Adolescents with malocclusion are often reminded of their condition, which can lead to avoiding strategies to minimize the negative feelings associated with the teeth and low self-esteem. Clinicians may therefore need to be aware of potential irrational behaviors when interacting with adolescents with malocclusions. The findings also suggest that there might be a discrepancy of attitudes between professionals focusing on oral health aspects of malocclusions and the adolescents focusing on esthetic aspects.

- Glucose-dependent insulinotropic polypeptide (GIP) is an incretin hormone with extrapancreatic effects beyond glycemic control. Here we demonstrate unexpected effects of GIP signaling in the vasculature. GIP induces the expression of the pro-atherogenic cytokine osteopontin (OPN) in mouse arteries, via local release of endothelin-1 (ET-1) and activation of cAMP response element binding protein (CREB). Infusion of GIP increases plasma OPN levels in healthy individuals. Plasma ET-1 and OPN levels are positively correlated in patients with critical limb ischemia. Fasting GIP levels are higher in individuals with a history of cardiovascular disease (myocardial infarction, stroke) when compared to controls. GIP receptor (GIPR) and OPN mRNA levels are higher in carotid endarterectomies from patients with symptoms (stroke, transient ischemic attacks, amaurosis fugax) than in asymptomatic patients; and expression associates to parameters characteristic of unstable and inflammatory plaques (increased lipid accumulation, macrophage infiltration and reduced smooth muscle cell content). While GIPR expression is predominantly endothelial in healthy arteries from human, mouse, rat and pig; remarkable up-regulation is observed in endothelial and smooth muscle cells upon culture conditions yielding a "vascular disease-like" phenotype. Moreover, a common variant rs10423928 in the GIPR gene associated with increased risk of stroke in type 2 diabetes patients.

Tidskriftsartikel (refereegranskat)abstract
- Aim. This observational study was undertaken in order to analyse whether any differences could be detected between diabetic and non-diabetic patients with critical limb ischemia (CLI) concerning the inflammatory response. Methods. A total number of 259 consecutive patients with CLI were treated between October 2001 and January 2003. Results. Among the 259 patients, 135 (52%) had diabetes, previously known in 123, and detected during hospitalization in 12. The diabetic patients more often showed gangrene (P < 0.05) and infra-inguinal atherosclerosis (84% vs 67%, P=0.001). The patients with diabetes showed a better lipid profile (total cholesterol 4.6 vs 5 mmol/L, P=0.006 and lower LDL-cholesterol (2.7 vs 3.1 mmol/L, P=0.010) despite the same frequency of statin treatment. They showed a higher creatinine (149 vs 117 pmol/L, P=0.0003) than the nondiabetic patients. Of the inflammatory markers, C-reactive protein (CRP) was equally elevated in both groups. Tumor necrosis factor-a (TNF-a) was increased among the diabetic patients (2.6 vs 1.8 pg/mL, P < 0.05), and this difference was most evident in those with gangrene. Neopterin was also higher among the diabetic patients (31 vs 21 mmol/L, P < 0.01), but CD40L was not different between groups. Conclusions. Diabetes mellitus was very common in CLI patients, and more often combined with renal impairment and infra-inguinal atherosclerosis. The inflammatory markers TNF-alpha and neopterin were elevated in patients with diabetes as compared to non-diabetic patients, but this difference cannot explain why CLI is 10 times more frequent in diabetic patients.
