RESUMEN
PURPOSE: Rectus diastasis (RD) associated with abdominal hernias present a surgical challenge associated with a paucity in treatment guidelines. The objective of this systematic review is to review surgical techniques and assess complication and recurrence rates of RD in patients with concurrent abdominal hernias. METHODS: PubMed and EMBASE databases were systematically searched, and data extraction was performed on articles which met the inclusion criteria. Pooled analyses of complication and recurrence rates were performed to compare open vs. minimally invasive surgery. Student t tests were performed to compare differences in continuous outcomes. RESULTS: Twenty-eight studies were included in this review. RD can be surgically repaired by both open and laparoscopic approaches using both non-absorbable and absorbable sutures. The majority of the techniques reported included mesh insertion either above the aponeurosis, retromuscular, preperitoneal, or intraperitoneal. Open techniques, compared to laparoscopic approaches, were associated with a significantly higher rate of skin dehiscence (6.79% vs. 2.86%; p = 0.003) and hematoma formation (4.73% vs. 1.09%; p < 0.001) and a significantly lower rate of post-operative seroma formation (2.47% vs. 8.29%; p < 0.001). No significant difference in RD recurrence rates were observed between open and laparoscopic repair (0.22 vs. 0.63%, p = 0.17). CONCLUSION: Both open and laparoscopic surgery are safe and effective methods that can be used to repair RD in patients with RD and concurrent abdominal hernias as evident by the low recurrence and complication rates and almost negligible major complications post repair.

BACKGROUND: ASN002 is an oral dual inhibitor of Janus kinase and spleen tyrosine kinase, which are involved in the pathogenesis of atopic dermatitis (AD) through their regulatory role on T helper (Th)1, Th2 and Th17/Th22 pathways. OBJECTIVES: The objectives of this study were to evaluate the efficacy, safety, pharmacokinetics and effects on systemic biomarkers of ASN002 in patients with moderate-to-severe AD. Methods A total of 36 patients with moderate-to-severe AD were randomized (3 : 1) to ASN002 or placebo in the phase Ib study. Three dosage cohorts were studied over a 28-day period (20 mg, 40 mg and 80 mg once daily). RESULTS: ASN002 was superior to placebo for the proportion of patients achieving Eczema Area and Severity Index (EASI) 50 (20 mg 20%, P = 0·93; 40 mg 100%, P = 0·003; 80 mg 83%, P = 0·03; placebo 22%), EASI 75 (20 mg 0%, P = 0·27; 40 mg 71%, P = 0·06; 80 mg 33%, P = 0·65; placebo 22%) and in change from baseline in pruritus (20 mg -1·3 ± 2·1, P = 0·81; 40 mg -3·1 ± 2·7, P = 0·27; 80 mg -4·7 ± 2·1, P = 0·01; placebo -1·6 ± 1·8). Adverse events were generally mild and similar across all groups. ASN002 showed dose-dependent plasma exposure with low interpatient variability, significantly downregulated several serum biomarkers involved in Th1, Th2 and Th17/Th22 immunity, and decreased the atherosclerosis-associated biomarker E selectin/SELE. CONCLUSIONS: In patients with moderate-to-severe AD, ASN002 showed strong efficacy with rapid onset of action and associated improvements in systemic inflammation.

BACKGROUND AND AIMS: Inflammatory bowel disease [IBD] can impair patients' functional capacity with significant negative effects on their quality of life. Our aim was to determine the impact of IBD diagnosis on fitness levels and to assess the levels of engagement in physical activity and fatigue in IBD patient before and after diagnosis. METHODS: A prospective multi-centre cross-sectional study was performed. Patients diagnosed with IBD in the previous 18 months were recruited. Inclusion criteria included clinical remission and/or no treatment changes within the previous 6 months. Physical exercise levels were assessed by the Godin score and fatigue levels was assessed by the functional assessment of chronic illness therapy [FACIT] score. RESULTS: In total, 158 patients (100 Crohn's disease [CD]) were recruited. Mean age was 35.1 years (95% confidence interval [CI] ± 2.0). Gender distribution was approximately equal [51.3% male]. The Mean Harvey Bradshaw and Simple Clinical Colitis Activity indices were 2.25 [95% CI ± 0.40] and 1.64 [95% CI ± 0.49], respectively. The mean Godin score difference before and after IBD diagnosis was 6.94 [p = 0.002]. Patients with ulcerative colitis [UC] [41.8%] were more likely than patients with CD [23.0%] to reduce their exercise levels [p = 0.04]. FACIT scores were lower in patients who had experienced relapses [p = 0.012] and had severe disease [p = 0.011]. Approximately one-third of patients reduced their activity level following IBD diagnosis. CONCLUSIONS: Patients were significantly less physically active after a diagnosis of IBD and this was more apparent in UC. Identification of the risk factors associated with loss of fitness levels would help to address the reduced patient quality of life.

INTRODUCTION: Vitamin K antagonist (VKA) treatment requires routine monitoring using the international normalized ratio (INR). However, different INR assays may vary in their results. The aim of this study was to assess the agreement of three different INR methods, compared with thrombin generation, in patients on VKA treatment. METHODS: Sixty patients attending the Anticoagulation Clinic at Mater Dei Hospital (Msida, Malta) for VKA monitoring between August and September 2015 were enrolled. The INR was tested using a point-of-care (POC) device (CoaguChek XS Plus, Roche Diagnostics) for both capillary and venous blood samples, a photo-optical (Sysmex CS-2100i/CA-1500, Siemens) and a mechanical clot detection system (Thrombolyzer XRC, Behnk Elektronik). All assays used human recombinant thromboplastin as reagent. Thrombin generation was performed using the calibrated automated thrombogram. RESULTS: There was a negative curvilinear correlation between the endogenous thrombin potential and different INR assays (r≤-.75) and a strong positive linear correlation between the CoaguChek XS Plus on capillary samples and the other INR methodologies (r≥.96). CONCLUSION: All different INR assays showed good correlation with the thrombin generation potential. The POC INR showed one of the highest correlation coefficients with thrombin generation, confirming the POC devices as an accurate, valid alternative to laboratory INR in VKA patients.

BACKGROUND: Natural Killer (NK) cells have been implicated in the development of allergic airway inflammation. However, the in vivo role of NK cells has not been firmly established due to the lack of animal models with selective deficiencies in NK cells. OBJECTIVE: To determine the specific contribution of NK cells in a murine model of allergic airway disease (AAD). METHODS: The role of NK cells in AAD was studied using NK-deficient (NKD) mice, perforin(-/-) mice, and mice depleted of Ly49A/D/G(+) NK cell subsets in an ovalbumin-induced model of allergic airway disease (OVA-AAD). RESULTS: Induction of OVA-AAD in C57BL/6 wild-type (WT) mice resulted in the expansion of airway NK cells and the development of pronounced airway eosinophilia. In the absence of NK cells or specific subsets of NK cells, either in NKD mice, or after the depletion of Ly49A/D/G(+) NK cells, the development of OVA-AAD was significantly impaired as seen by decreased airway inflammation and eosinophilia, decreased secretion of the Th2 cytokines IL-4, IL-5 and IL-13 and diminished OVA-specific antibody production. Furthermore, while OVA-exposure induced a dramatic expansion of dendritic cells (DCs) in WT mice, their induction was significantly attenuated in NKD mice. Development of OVA-AAD in perforin(-/-) mice suggested that the proinflammatory role of NK cells is not dependent on perforin-mediated cytotoxicity. Lastly, induction of allergic disease by OVA-specific CD4 T cells from WT but not NK-depleted or NKD mice in RAG(-/-) recipients, demonstrates that NK cells are essential for T cell priming. CONCLUSIONS AND CLINICAL RELEVANCE: Our data demonstrate that conventional NK cells play an important and distinct role in the development of AAD. The presence of activated NK cells has been noted in patients with asthma. Understanding the mechanisms by which NK cells regulate allergic disease is therefore an important component of treatment approaches.
