Factor V Leiden (FVL) is associated with venous thrombosis; however, an association between FVL and arterial thrombosis remains controversial. We investigated FVL as a risk factor for myocardial infarction (MI), ischemic stroke (IS), or non-MI ischemic heart disease (non-MI-IHD).
BackgroundNeoadjuvant chemotherapy or chemoradiotherapy is used widely before tumour resection in cancer of the gastro‐oesophageal junction (GOJ). Strategies to improve treatment tolerability are warranted. This study examined the safety and feasibility of preoperative exercise training during neoadjuvant treatment in these patients.MethodsPatients were allocated to a standard‐care control group or an exercise group, who were prescribed standard care plus twice‐weekly high‐intensity aerobic exercise and resistance training sessions. The primary endpoint was the incidence of serious adverse events (SAEs) that prevented surgery, including death, disease progression or physical deterioration. Preoperative hospital admission, postoperative complications, changes in patient‐reported quality of life and pathological treatment response were also recorded. In the exercise group, adherence to exercise and changes in aerobic fitness, muscle strength and body composition were measured.ResultsThe incidence of SAEs was not increased in the exercise group. The risk of failure to reach surgery was 5 versus 21 per cent in the control group (risk ratio (RR) 0·23, 95 per cent c.i. 0·04 to 1·29), the risk of preoperative hospital admission was 15 versus 38 per cent respectively (RR 0·39, 0·12 to 1·23) and the risk of postoperative complications was 58 versus 57 per cent (RR 1·06, 0·61 to 1·73). The exercise group attended a mean of 17·5 sessions, and improved fitness, muscle strength and Functional Assessment of Cancer Therapy — Esophageal (FACT‐E) total score compared with the baseline level.ConclusionPreoperative exercise training during neoadjuvant treatment in patients with GOJ cancer is safe and feasible, with improvements in fitness, strength and quality of life. Preoperative exercise training may be associated with a lower risk of critical SAEs that preclude surgery or result in hospitalization.
Elevated fibrinogen predicts future ischaemic strokes, particularly in men and in the young and middle aged. This is most likely a reflection of advanced atherosclerosis, rather than an association with rupture-prone plaques.
SUMMARYTransfer of 2 2 10 5 congenic or semiallogenic purified TCR®¯ CD4 T cells to SCID mice leads to an infiltration of the recipient gut lamina propria and epithelium with a donor-derived CD4T cell subset which induces a lethal inflammatory bowel disease (IBD) in the recipients. In contrast, IBD was not observed in SCID mice transplanted with unfractionated splenic cells. The earliest detectable pathological changes after CD4T cell transfer were proliferation and hypertrophy of the entire colonic epithelial layer, including increased mitotic activity, increased expression of epithelial nuclear proliferation antigen, and elongation of the crypts. Later on, massive mononuclear cell infiltration, hypertrophy of all layers of the colon and occasional epithelial ulcerations were observed. At this stage, accumulations of IgA, IgM and small numbers of IgG1-, IgG2-and IgG3-secreting plasma cells were present in the lamina propria of both the small and large intestine. We conclude that low numbers of intraveneously transferred CD4T cells induce IBD in SCID mice. In the late stages of CD4 T cellinduced IBD, the colonic lamina propria becomes infiltrated with macrophages, neutrophils and plasma cells secreting IgA, IgM, and to a lesser degree IgG antibodies which might play an accessory role in the pathogenesis of IBD.
Aim To compare the peri- and postoperative data between a hybrid minimally invasive esophagectomy (HMIE) and the conventional Ivor Lewis esophagectomy. Methods Retrospective comparison of perioperative characteristics, postoperative complications, and survival between HMIE and Ivor Lewis esophagectomy. Results 216 patients were included, with 160 procedures performed with the conventional and 56 with the HMIE approach. Lower perioperative blood loss was found in the HMIE group (600 ml versus 200 ml, p < 0.001). Also, a higher median number of lymph nodes were harvested in the HMIE group (median 28) than in the conventional group (median 23) (p = 0.002). The median length of stay was longer in the conventional group compared to the HMIE group (11.5 days versus 10.0 days, p = 0.03). Patients in the HMIE group experienced fewer grade 2 or higher complications than the conventional group (39% versus 57%, p = 0.03). The rate of all pulmonary (51% versus 43%, p = 0.32) and severe pulmonary complications (38% versus 18%, p = 0.23) was not statistically different between the groups. Conclusions The HMIE was associated with lower intraoperative blood loss, a higher lymph node harvest, and a shorter hospital stay. However, the inborn limitations with the retrospective design stress a need for prospective randomized studies. Registration number is DRKS00013023.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
