Nutrition surveys suggest that &lt;10% of Canadian adults have inadequate riboflavin intakes. However, biochemical riboflavin deficiency [erythrocyte glutathione reductase activity coefficient (EGRac)≥1.40] has been reported in 41% of young adult women living in Metro Vancouver. Canadian Chinese ethnicity comprise&gt;25%of Vancouver's population and are postulated to have poorer riboflavin status than those of European ethnicity because they could be less likely to consume dairy products and fortified wheat.<br /><br /> The objectives of this study were to determine dietary riboflavin intake and food sources, and to assess the association between riboflavin intake and status in young women of European (<br /><br /> =107) and Chinese (<br /><br /> =91) ethnicities living in Metro Vancouver, Canada.<br /><br /> This was a cross-sectional study conducted in women (aged 19-45 y). Women were healthy, not pregnant or breastfeeding, of European or Chinese ethnicities, and not taking riboflavin-containing supplements for the past 4 mo. Dietary riboflavin iroductive age living in Metro Vancouver, Canada, had a low prevalence of inadequate dietary riboflavin intake despite the high prevalence of apparent biochemical riboflavin deficiency.Repeat hepatectomy for recurrent colorectal liver metastases (CRLM) for the remnant hemiliver is sometimes challenging due to the insufficient future liver remnant (FLR) volume. We present an aggressive strategy for resection of the recurrent CRLM involving bisegmentectomy of the remnant right hemiliver with the aid of portal vein embolization (PVE) and venous reconstruction. The patient was a 50-year-old woman who had undergone left hemihepatectomy for a CRLM 10 months ago. Three metastatic tumors were found in the remnant segments 7 and 8 (S7&amp;8) of the liver, and one of them involved the right hepatic vein (RHV). Conducting bisegmentectomy of S7&amp;8 with resection of the RHV, the non-congestive FLR volume was calculated as 34.9% of the remnant total liver volume, which was deemed insufficient considering the mild liver damage after repeated chemotherapy. After trans-ileocecal PVE of the portal branches in S7&amp;8 in a hybrid angio room, the non-congestive FLR volume increased to 42.3%, which could be further advanced to 58.0% if the RHV was reconstructed. Segmentectomies of S7&amp;8 with resection and reconstruction of the RHV using the right superficial femoral vein graft was performed. The patient was discharged without any complications, and the postoperative computed tomography (CT) scan showed the good patency of the reconstructed venous graft. Aggressive segmentectomies and venous reconstruction of the remnant hemiliver after PVE might be a new strategy to overcome the insufficient FLR volume.<br /><br /> Diffusion-weighted magnetic resonance imaging (DWI-MRI) is used to predict tumor malignancy. Here we explored the role of apparent diffusion coefficient (ADC) values in the treatment of patients with resectable colorectal liver metastasis (CRLM).<br /><br /> Magnetic resonance imaging (MRI) scans were conducted using a Signa HDe or Signa Explorer 1.5-T scanner (GE Healthcare). ADC maps were calculated using DWI with <br /><br /> values of 0, 20, and 800s/mm<br /><br /> . We enrolled 60 patients who underwent upfront hepatic resection for CRLM and divided them into ADC-high (n=30) and ADC-low (n=30) groups. Clinicopathological variables of the groups were compared. Immunohistochemical analysis of HIF-1α expression in tumor tissues was performed, and the relationship between the ADC value and HIF-1α expression was evaluated.<br /><br /> The disease-free survival rate of the ADC-low group was significantly lower than that of the ADC-high group (<br /><br /> &lt;.05). Univariate analysis revealed that tumor number (more than five), synchronous metastasis, and low ADC were prognostic factors. Multivariate analysis identified low ADC as an independent prognostic factor.

Transferrin level was directly proportional to total iron-binding capacity (TIBC), and TIBC&lt;250μg/dl was defined as low transferrin. The associations between transferrin and prognosis were evaluated in univariate and multivariate Cox proportional hazards analyses.<br /><br /> Fifty-eight of 501 patients (11.5%) had low transferrin. In these patients, low transferrin was significantly associated with high age, female gender, low body mass index (&lt;18.5), high white blood cell count, low total protein, low albumin, high C-reactive protein, low hemoglobin, and low neutrophil/lymphocyte ratio. In the univariate analysis, low transferrin was associated with shorter relapse-free survival (RFS) (hazard ratio [HR] 2.180, 95% confidence interval [CI] 1.417-3.354, <br /><br /> &lt;.001), overall survival (OS) (HR 2.930, 95% CI 1.784-4.811, <br /><br /> &lt;.001), and cancer-specific survival (CSS) (HR 2.122, 95% CI 1.053-4.275, <br /><br /> =.035). In multivariate analysis, high age (<br /><br /> &lt;.001), Glasgow Prognostic Score (<br /><br /> =.009), and low transferrin (HR 2.336, 95% CI 1.173-4.654, <br /><br /> =.011) were independently associated with shorter OS, and depth of invasion pT4 (<br /><br /> =.015), presence of lymph node metastasis (<br /><br /> =.001), low hemoglobin (<br /><br /> =.034), and low transferrin (HR 2.638, 95% CI 1.113-5.043, <br /><br /> =.025) were independently associated with shorter CSS.<br /><br /> Preoperative serum transferrin in Stage I-III CRC patients was identified as a novel prognostic marker by univariate and multivariate analyses.<br /><br />Preoperative serum transferrin in Stage I-III CRC patients was identified as a novel prognostic marker by univariate and multivariate analyses.<br /><br /> Appendicitis is divided into two categories complicated appendicitis (CA) and uncomplicated appendicitis (UA). In pediatric patients with CA, the use of interval appendectomy (IA), which is non-operative management followed by elective surgery, has decreased the number of postoperative complications. Before discussing the merit of IA for adult patients, we need to clarify whether the frequency and seriousness of the complication rate after emergency surgery is higher for CA than for UA.<br /><br /> This retrospective cohort study included adult patients who underwent appendectomy and who were registered in the National Clinical Database (NCD) from 2014 to 2016. Patients with CA who underwent emergency appendectomy comprised the CA group. Patients with UA comprised the UA group. Patients with chronic or recurrent appendicitis who underwent elective appendectomy comprised the elective appendectomy (EA) group. Primary outcomes were all morbidity, serious morbidity, and mortality within 30days after appendectomy.<br /><br /> We included 109256 patients in the study 14798 CA, 86876 UA, and 7582 EA patients.
