Introduction Coronavirus 2 (CoV-2) infection or coronavirus disease 2019 (COVID-19) is frequently associated with microvascular thrombosis.The microthrombosis in COVID-19 is the result of the interplay between inflammation and endotheliopathy. Elevated interleukin-6 (IL-6) characterizes COVID-19 inflammation resulting in endotheliopathy and coagulopathy marked by elevated D-dimer (DD). Aim of this study is to identify and to describe the coagulation changes in 100 moderate COVID-19 patients having lung involvement and to determine the association of coagulopathy with the severity and prognosis. Methods Inflammation, endothelial and coagulation molecules were measured in moderate and mild disease. Results IL-6 and tumor necrosis factor-α (TNF-α) and tissue factor (TF), von Willebrand factor (VWF), and tissue factor pathway inhibitor (TFPI) significantly increased in moderate disease as well as D-dimer, thrombin antithrombin complex (TAT), Fibrinogen (Fib), platelet factor-4 (PF4), β-thromboglobulin (β-TG), P-selectin, and platelet adhesion. Shortened clotting time (CT) and clot formation time (CFT), high maximum clot firmness (MCF) and low LY at 30 min were present in 100% of moderate COVID-19 patients compared with mild COVID-19 patients. Conclusions These findings demonstrate that moderate COVID-19 has a profound inflammation associated with severee ndotheliopathy and intense coagulation activation uncontrolled by TFPI. Attention should be paid to coagulopathy in COVID-19. Closely monitoring of coagulation and application of appropriate anticoagulation may improve the prognosis of moderate COVID-19 and to prevent the progression to severe COVID-19 disease.

These data suggest that laparoscopic surgery induces activation of coagulation and fibrinolytic pathways and, additionaly, betaTG elevation, which has never been reported and might account for postoperative platelet activation and a greater risk of thrombogenicity. Therefore, routine thromboembolic prophylaxis in patients undergoing laparoscopic surgery is recommended.

Low-molecular-weight heparin should be administered to all patients who have been splenectomised, especially if they are at high risk of PVT. If symptoms appear, patients need to be treated with high-dose heparin followed, after at least 3 weeks, by oral anticoagulant therapy.

Background and Objectives:The aim of this study was to evaluate the results of laparoscopic surgery performed for coexisting spleen and gallbladder surgical diseases.Methods:Between May 2004 and October 2012, 12 patients underwent concomitant laparoscopic splenectomy and cholecystectomy. Indications for surgery included idiopathic thrombocytopenic purpura in 5 patients, hereditary spherocytosis in 4 patients, and thalassemia intermedia in 3 patients.Results:The mean operative time was 100 minutes (range, 80–160 minutes), and the blood loss ranged from 0 to 150 mL (mean, 50 mL). The mean longitudinal diameter of the spleen was 14 cm. One patient required conversion to open procedure. An accessory spleen was detected and removed in one case. The mean length of hospital stay was 5 days. No deaths or other major intraoperative and/or postoperative complications occurred.Conclusion:Provided that the technique is performed by an experienced surgical team, concomitant laparoscopic splenectomy and cholecystectomy is a safe and feasible procedure and may be considered for coexisting spleen and gallbladder diseases.

The authors report data obtained from a 3-year study of CSII and humanized insulin (semi-synthetic human insulin) administered to 18 insulin-dependent subjects in the outpatient clinic. The aim of this study was to evaluate the validity of insulin pumps in long-term treatment. Metabolic parameters were significantly improved (p less than 0.001) in the first month and remained so with only slight alterations throughout treatment. The authors underline some metabolic problems (ketosis) caused by malfunctioning of the insulin pumps, by the difficulties with the infusion system or by nodular skin lesions at the infusion site. Only these lesions called for treatment to be discontinued in 4 patients. The highest incidence of nodular skin lesions was seen after one year's uninterrupted treatment and they seem connected to the duration of treatment rather than to the patients' negligence (inadequate hygiene, delayed needle substitution). The authors conclude that CSII treatment is valid over short-term periods, whereas it presents drawbacks over long-term administration.

Background Spontaneous pregnancy loss and implantation failure after assisted reproductive technologies (ART) are very common occurrences. Although 50–60% of all cases remains unexplained, various predisposing factors, including thrombophilias, have been identified. Thus, the potential benefit of a prophylaxis with low-molecular-weight heparins in improving outcomes has been often investigated over the years. However, the majority of studies are observational and results from randomized clinical trials (RCTs) are inconclusive, probably due to heterogeneity and limited sample size. To cover these unmet needs and to have further data mainly based on the real-life clinical management, we designed these multicenter registries. Methods OTTILIA (Observational sTudy on antiThrombotic prevention in thrombophILIA and pregnancy loss) and FIRST (recurrent Failures in assIsted Reproductive Techniques) registries are two prospective, multicenter, observational studies to evaluate pregnancy or ART outcomes in consecutive women with previous reproductive failures after spontaneous or assisted conception, respectively. All enrolled women are observed from their first visit after positive pregnancy test (OTTILIA) or before commencing a new ART cycle (FIRST) until the end of pregnancy or ART procedure (negative pregnancy test/end of pregnancy, if successful cycle), respectively. Data are collected by means of questionnaires and recorded in a central database. Follow-up investigations are performed during hospital stay, routine clinical follow-up visits or telephone interviews. Primary outcome is live birth rate in the OTTILIA register and clinical pregnancy rate in the FIRST. Discussion Although RCTs are the ‘gold standard’ for evaluating treatment outcomes, we believe that our registries represent a valid alternative in improving knowledge on mechanisms involved in reproductive failures and supporting future clinical decisions.

The use of surgical drain after abdominal surgery has always been a controversial issue.Benefits and risks related to the operatively placed drains in the abdominal cavity have been discussed since a hundred years ago when some surgeons where in favor of the drainage, while skeptic others considered not physiological their use (1, 2).In the common practice intra-abdominal drains have been used to help the surgeons in the post-operative phase to identify post-operative bleeding, to drain and monitor residual intraperitoneal pathologic liquids (such as bile, fecal material, pancreatic juice), and in order to prevent intra-abdominal septic collections (3).So far, however, there is a lack of evidence proving significant benefits of surgical drains and, moreover, drains themselves have been imputed as responsible for related complications which may increase post-operative morbility (1,(4)(5)(6)(7)(8)(9)(10)(11)(12).Similarly, placement of drains after splenectomy has been largely debated. Theoretically, the use of drain in splenectomised patients, whose susceptibility to infections and sepsis due to some microbial agents is well known, might predispose to an increased risk of subphrenic abscess formation and systemic infections (13,14). This assertion, however, has been resized in other studies (15-17). The increased risk of loco-regional or systemic infections in drained patients following splenectomy, has been related to associated, not intra-operatively recognized, injuries to the pancreatic tail and/or to the bowel, or they have been ascribed to the drainage system itself (18).In this study, we report our experience in a large series of open and laparoscopic splenectomies where the left sub-phrenic drainage has been routinely used. We attempt to answer if in our experience drainage could have
