- Objective: The aim of our study is to assess the association between preoperative level of activity and recovery after breast cancer surgery measured as hospital stay, length of sick leave and self-assessed physical and mental recovery. Design: A prospective cohort study. Setting: Patients included were those scheduled to undergo breast cancer surgery, between February and November 2013, at two participating hospitals in the Western Region of Sweden. Participants: Patients planned for breast cancer surgery filled out a questionnaire before, as well as at 3 and 6 weeks after the operation. The preoperative level of activity was self-assessed and categorised into four categories by the participants using the 4-level SaltinGrimby Physical Activity Level Scale (SGPALS). Main outcome measure: Our main outcome was postoperative recovery measured as length of sick leave, in-hospital stay and self-assessed physical and mental recovery. Results: 220 patients were included. Preoperatively, 14% (31/220) of participants assessed themselves to be physically inactive, 61% (135/220) to exert some light physical activity (PA) and 20% (43/220) to be more active (level 3+4). Patients operated with mastectomy versus partial mastectomy and axillary lymph node dissection versus sentinel node biopsy were less likely to have a short hospital stay, relative risk (RR) 0.88 (0.78 to 1.00) and 0.82 (0.70 to 0.96). More active participants (level 3 or 4) had an 85% increased chance of feeling physically recovered at 3 weeks after the operation, RR 1.85 (1.20 to 2.85). No difference was seen after 6 weeks. Conclusions: The above study shows that a higher preoperative level of PA is associated with a faster physical recovery as reported by the patients 3 weeks post breast cancer surgery. After 6 weeks, most patients felt physically recovered, diminishing the association above. No difference was seen in length of sick leave or self-assessed mental recovery between inactive or more active patients.

- OBJECTIVES: Evidence suggests that patients with irritable bowel syndrome (IBS) have an altered cytokine profile, although it is unclear whether cytokines are linked with symptom severity. We aimed to determine whether global serum and mucosal cytokine profiles differ between IBS patients and healthy subjects and whether cytokines are associated with IBS symptoms. METHODS: Serum from 144 IBS patients and 42 healthy subjects was analyzed for cytokine levels of interleukin (IL)-5, IL-6, IL-8, IL-10, IL-12p70, IL-13, IL-17A, interferon (IFN)-gamma and tumor necrosis factor (TNF) by MSD MULTI-ARRAY. In total, 109 IBS and 36 healthy sigmoid colon biopsies were analyzed for mRNA expression of IL-8, IL-10, TNF, and FOXP3 by quantitative reverse transcription PCR. Multivariate discrimination analysis evaluated global cytokine profiles. Rectal sensitivity, oroanal transit time, and psychological and gastrointestinal symptom severity were also assessed. RESULTS: Global cytokine profiles of IBS patients and healthy subjects overlapped, but cytokine levels varied more in IBS patients. Serum levels of IL-6 and IL-8 tended to be increased and levels of IFN-gamma tended to be decreased in IBS patients. Mucosal mRNA expression of IL-10 and FOXP3 tended to be decreased in IBS patients. Within both the full study cohort and IBS patients alone, serum level of TNF was associated with looser stool pattern, while subjects with more widespread somatic symptoms had increased serum levels of IL-6. Although neither IBS bowel habit subgroups nor patients with possible post-infectious IBS were associated with distinct cytokine profiles, a small cluster of IBS patients with comparatively elevated immune markers was identified. CONCLUSIONS: Global cytokine profiles did not discriminate IBS patients from healthy subjects, but cytokine profiles were more varied among IBS patients than among healthy subjects, and a small subgroup of patients with enhanced immune activity was identified. Also, association of inflammatory cytokines with some clinical symptoms suggests that immune activation may be of importance in a subset of IBS patients.

- Objective The effects of dietary interventions on gut bacteria are ambiguous. Following a previous intervention study, we aimed to determine how differing diets impact gut bacteria and if bacterial profiles predict intervention response. Design Sixty-seven patients with IBS were randomised to traditional IBS (n=34) or low fermentable oligosaccharides, disaccharides, monosaccharides and polyols (FODMAPs) (n=33) diets for 4 weeks. Food intake was recorded for 4 days during screening and intervention. Faecal samples and IBS Symptom Severity Score (IBS-SSS) reports were collected before (baseline) and after intervention. A faecal microbiota dysbiosis test (GA-map Dysbiosis Test) evaluated bacterial composition. Per protocol analysis was performed on 61 patients from whom microbiome data were available. Results Responders (reduced IBS-SSS by >= 50) to low FODMAP, but not traditional, dietary intervention were discriminated from non-responders before and after intervention based on faecal bacterial profiles. Bacterial abundance tended to be higher in non-responders to a low FODMAP diet compared with responders before and after intervention. A low FODMAP intervention was associated with an increase in Dysbiosis Index (DI) scores in 42% of patients; while decreased DI scores were recorded in 33% of patients following a traditional IBS diet. Non-responders to a low FODMAP diet, but not a traditional IBS diet had higher DI scores than responders at baseline. Finally, while a traditional IBS diet was not associated with significant reduction of investigated bacteria, a low FODMAP diet was associated with reduced Bifidobacterium and Actinobacteria in patients, correlating with lactose consumption. Conclusions A low FODMAP, but not a traditional IBS diet may have significant impact on faecal bacteria. Responsiveness to a low FODMAP diet intervention may be predicted by faecal bacterial profiles.

- BackgroundThe autonomic nervous system (ANS) modulates intestinal inflammation in animal models. Human evidence confirming such modulating influence is limited. We aimed to investigate whether ANS function is associated with inflammatory parameters at disease onset, and whether it predicts the evolution of inflammation in patients with ulcerative colitis (UC). MethodsWe prospectively monitored 51 patients from onset of UC for 3 years. Upon remission of the onset flare, ANS activity was assessed by heart rate variability analysis and compared with healthy controls. Inflammatory parameters in blood, stool, and colonic biopsies obtained at onset and during follow-up visits were analyzed. Generalized linear models were used to test cross-sectional associations between ANS activity and inflammatory parameters at onset; linear mixed models were used to test whether ANS function at onset predicted the evolution of inflammation over the following 3 years. Key ResultsSympathovagal balance was different in UC patients compared to healthy controls, and cross-sectional associated with higher levels of systemic (erythrocyte sedimentation rate [ESR], CRP, TNF-, IFN-) and mucosal inflammation (interleukin-8, IFN-) at onset. Conversely, a negative cross-sectional association with parasympathetic activity was found for ESR & TNF-. Longitudinally, parasympathetic activity at onset predicted systemic (ESR, WBC), but not mucosal inflammation during follow-up. Conclusions & InferencesThis study further strengthens the association between the ANS system and intestinal inflammation previously found in animal models and recently in patients with inflammatory bowel disease. These results may have important implications for the pathogenesis and treatment of UC.

- Background: Patients with ulcerative colitis often report fatigue. Objectives: To investigate prevalence of and risk factors for fatigue in patients with ulcerative colitis with active disease and during deep remission. Methods: In this cross-sectional study, disease activity was evaluated with endoscopy and calprotectin, and patients were classified as having active disease (n=133) or being in deep remission (n=155). Blood samples were analysed to assess anaemia, iron deficiency and systemic immune activity. Patients completed questionnaires to assess fatigue, psychological distress, gastrointestinal symptoms and quality of life. Results: The prevalence of high fatigue (general fatigue >= 13, Multidimensional Fatigue Inventory) was 40% in the full study population. Among patients with high fatigue, female gender and iron deficiency were more prevalent, and these patients had more severe disease activity and reported higher levels of anxiety, depression and decreased quality of life compared with patients with no/mild fatigue. A logistic regression analysis identified probable psychiatric disorder (odds ratio (OR) (confidence interval) 6.1 (3.1-12.2)), iron deficiency (OR 2.5 (1.2-5.1)), active disease (OR 2.2 (1.2-3.9)) and female gender (OR 2.1 (1.1-3.7)) as independent risk factors for high fatigue. Similar results were found concerning psychological distress, gender and quality of life, but immune markers did not differ in patients in deep remission with high vs. no/mild fatigue. Conclusions: Probable psychiatric disorder, iron deficiency, active disease and female gender are independent risk factors for high fatigue in patients with ulcerative colitis. Low-grade immune activity does not seem to be the cause of fatigue among patients in deep remission.

Tidskriftsartikel (refereegranskat)abstract
- Background: Giant parathyroid adenoma is a rare type of parathyroid adenoma defined as weighing > 3.5 g. They present as primary hyperparathyroidism but with more elevated laboratory findings and more severe clinical presentations due to the larger tissue mass. This is the first reported case of giant parathyroid adenoma from the Middle East.Case presentation: A 52-year-old Indian woman presented with a palpable right-sided neck mass and generalized fatigue. Investigations revealed hypercalcemia with elevated parathyroid hormone and an asymptomatic kidney stone. Ultrasound showed a complex nodule with solid and cystic components, and Sestamibi nuclear scan confirmed a giant parathyroid adenoma. Focused surgical neck exploration was done and a giant parathyroid adenoma weighing 7.7 gm was excised.Conclusions: Giant parathyroid adenoma is a rare cause of primary hyperparathyroidism and usually presents symptomatically with high calcium and parathyroid hormone levels. Giant parathyroid adenoma is diagnosed by imaging and laboratory studies. Management is typically surgical, aiming at complete resection. Patients usually recover with no long-term complications or recurrence.

First sliding Amyand hernia harbouring appendicular schistosomiasis : Case report
- 2019
-
Ingår i: International Journal of Surgery Case Reports. - : Elsevier. - 2210-2612. ; 63, s. 143-146
-
Tidskriftsartikel (refereegranskat)abstract
- Introduction: Amyand's hernia (AH) is rare, schistosomiasis of the appendix is very uncommon, and both conditions coexisting together is an extremely rare event. Pre-operative diagnosis of each of the two conditions is usually difficult. To the best of our knowledge, the current paper is first to report both these two conditions in coexistence. Presentation of case: A 31-year old man who had no comorbidities was admitted electively as a day case of non-complicated right indirect inguinal hernia. Further history and physical examination were unremarkable. Intraoperatively the patient was found to have right sliding AH with appendicular schistosomiasis (AS). The patient underwent Lichtenstein repair of the hernia with appendectomy. On follow up he was referred to infectious disease clinic, and the post-operative course was uneventful. Conclusions: Intraoperative identification of non-typical hernia sac before its opening should alert the surgeon to the possibility of sliding hernia and the presence of an organ as a part of the sac. Rare causes of appendicular masses like schistosomiasis granuloma should be considered in endemic areas or immigrants from these areas, despite the difficulty of preoperative diagnosis. Management should follow general guidelines of appendectomy, hernia repair and dealing with the associated pathology if present.

- Background: Varicella zoster virus presents clinically as primary (chickenpox) or secondary (herpes zoster) infection. Cutaneous and extracutaneous dissemination may occur, usually in immunocompromised patients. VZV hepatitis that progresses to fulminant hepatic failure is very rare and fatal. To the best of our knowledge, 9 cases have been reported to date, of which 7 were in immunocompromised adults, and only one patient was on short duration steroid therapy. Presentation of case: We present a 26-year old man who was admitted initially with acute abdomen as query persistent biliary colic. Later, he showed clinical and laboratory findings of VZV hepatitis that progressed rapidly despite maximal medical ICU support and he expired on day 3 of admission. Conclusions: Acute VZV infection may present as fulminant hepatitis. The presentation may initially be challenging for the diagnosis and should be considered if the patient has been in contact with a sick case. Low dose corticosteroid could carry a risk for fatal VZV fulminant hepatitis and should be used very cautiously especially with VZV patients’ contacts. Further causative relationships remain to be established.

- OBJECTIVE: Anti-TNF-α treatment constitutes a mainstay in the treatment of Crohn's disease (CD), but its mechanisms of action are not fully understood. We aimed to investigate the effects of adalimumab, a human monoclonal TNF-α antibody, on macrophage (MQ) and dendritic cell (DC) subsets in mucosal biopsies and peripheral blood.MATERIAL AND METHODS: Intestinal biopsies and blood samples were obtained from 12 different CD patients both before and 4 weeks after the initiation of the induction of adalimumab treatment. Endoscopic disease activity was estimated by the Simple Endoscopic Score for Crohn's Disease. Biopsies were obtained from inflamed and non-inflamed areas. The numbers of lamina propria CD14 (+) DR(int) and CD14 (+) DR(hi) MQs, CD141(+), CD141(-) and CD103(+ )DCs subsets, and circulating monocytes and DCs were analyzed using flow cytometry.RESULTS: At baseline, we observed higher numbers of DR(int) MQs and lower numbers of CD103(+ )DCs in inflamed versus non-inflamed mucosa [843 vs. 391/10(5) lamina propria mononuclear cells (LPMCs) (p < 0.05) and 9 vs. 19 × 10(5) LPMCs (p = 0.01), respectively]. After four weeks of adalimumab treatment, the numbers of DR(int) MQs decreased [843 to 379/10(5) LPMCs (p = 0.03)], whereas the numbers of CD103(+ )DCs increased [9-20 × 10(5) LPMCs (p = 0.003)] compared with baseline. In peripheral blood, no alterations were observed in monocyte or DC numbers between baseline and week 4.CONCLUSIONS: In CD, mucosal inflammation is associated with high numbers of DR(int) MQs and low numbers of CD103(+ )DCs. This composition of intestinal myeloid subsets is reversed by anti-TNF-α treatment. These results suggest that DR(int) MQs play a pivotal role in CD inflammation.

- Background and study aims: Hepatocellular carcinoma (HCC) with extrahepatic metastasis has been studied, however, data from the Middle East remain scarce. In this study, we assess epidemiology of HCC in Qatar, and identify predictors of the metastatic behaviour. Patients and methods: All newly-diagnosed HCC patients on top of liver cirrhosis between 2011 and 2015 were included in the study. Results: A total of 180 patients met our inclusion criteria. The mean age was 58.8 ± 10.5 years with a mean follow-up of 1.0 ± 1.1 years. There were 150 male patients and HCV was the most common cause of liver cirrhosis 108 (60%), and 22 (12.2%) patients were classified as Child-Pugh class C. The overall survival of 51.1%, and 47 (26%) had at least one extrahepatic metastasis at the time of diagnosis. Single site metastasis was diagnosed in 10 patients, whereas 37 patients had multiple sites metastases. We compared patients who had metastases with patients who did not have metastasis at the time of diagnosis of HCC regarding several variables, and analysis revealed that tumour diameter larger than 5 cm (OR = 6.10, 95% CI = 1.85–20.12) (p = 0.003), and bilobar liver involvement (OR = 5.49, 95% CI = 1.10–27.30) (p = 0.037) were independent predictors of metastatic behaviour of HCC. Conclusion: The incidence of HCC is rising in our population, extrahepatic metastasis is no longer rare and tumours larger than 5 cm and bilobar involvement are determinants of the extrahepatic metastasis. © 2019 Pan-Arab Association of Gastroenterology
