Abstract
BACKGROUND Folate-mediated 1-carbon metabolism requires several nutrients, including vitamin B6. Circulating biomarker concentrations indicating high vitamin B6 status are associated with a reduced risk of colorectal cancer (CRC). However, little is known about the effect of B6 status in relation to clinical outcomes in CRC patients. OBJECTIVES We investigated survival outcomes in relation to vitamin B6 status in prospectively followed CRC patients. METHODS A total of 2031 patients with stage I-III CRC participated in 6 prospective patient cohorts in the international FOCUS (folate-dependent 1-carbon metabolism in colorectal cancer recurrence and survival) Consortium. Preoperative blood samples were used to measure vitamin B6 status by the direct marker pyridoxal 5'-phosphate (PLP), as well as the functional marker HK-ratio (HKr)[3'-hydroxykynurenine: (kynurenic acid + xanthurenic acid + 3'-hydroxy anthranilic acid + anthranilic acid)]. Using Cox proportional hazards regression, we examined associations of vitamin B6 status with overall survival (OS), disease-free survival (DFS), and risk of recurrence, adjusted for patient age, sex, circulating creatinine concentrations, tumor site, stage, and cohort. RESULTS After a median follow-up of 3.2 y for OS, higher preoperative vitamin B6 status as assessed by PLP and the functional marker HKr was associated with 16-32% higher all-cause and disease-free survival, although there was no significant association with disease recurrence (doubling in PLP concentration: HROS, 0.68; 95% CI: 0.59, 0.79; HRDFS, 0.84; 95% CI: 0.75, 0.94; HRRecurrence, 0.96; 95% CI: 0.84, 1.09; HKr: HROS, 2.04; 95% CI: 1.67, 2.49; HRDFS, 1.56; 95% CI: 1.31, 1.85; HRRecurrence, 1.21; 95% CI: 0.96,1. 52). The association of PLP with improved OS was consistent across colorectal tumor site (right-sided colon: HROS, 0.75; 95% CI: 0.59, 0.96; left-sided colon: HROS, 0.71; 95% CI: 0.55, 0.92; rectosigmoid junction and rectum: HROS, 0.61; 95% CI: 0.47, 0.78). CONCLUSION Higher preoperative vitamin B6 status is associated with improved OS among stage I-III CRC patients.

Abstract
BACKGROUND Folates, including folic acid, may play a dual role in colorectal cancer development. Folate is suggested to be protective in early carcinogenesis but could accelerate growth of premalignant lesions or micrometastases. Whether circulating concentrations of folate and folic acid, measured around time of diagnosis, are associated with recurrence and survival in colorectal cancer patients is largely unknown. METHODS Circulating concentrations of folate, folic acid, and folate catabolites p-aminobenzoylglutamate and p-acetamidobenzoylglutamate were measured by liquid chromatography-tandem mass spectrometry at diagnosis in 2024 stage I-III colorectal cancer patients from European and US patient cohort studies. Multivariable-adjusted Cox proportional hazard models were used to assess associations between folate, folic acid, and folate catabolites concentrations with recurrence, overall survival, and disease-free survival. RESULTS No statistically significant associations were observed between folate, p-aminobenzoylglutamate, and p-acetamidobenzoylglutamate concentrations and recurrence, overall survival, and disease-free survival, with hazard ratios ranging from 0.92 to 1.16. The detection of folic acid in the circulation (yes or no) was not associated with any outcome. However, among patients with detectable folic acid concentrations (n = 296), a higher risk of recurrence was observed for each twofold increase in folic acid (hazard ratio = 1.31, 95% confidence interval = 1.02 to 1.58). No statistically significant associations were found between folic acid concentrations and overall and disease-free survival. CONCLUSIONS Circulating folate and folate catabolite concentrations at colorectal cancer diagnosis were not associated with recurrence and survival. However, caution is warranted for high blood concentrations of folic acid because they may increase the risk of colorectal cancer recurrence.

Abstract
Chromosomal microarray analysis (CMA) is currently considered a first-tier diagnostic assay for the investigation of autism spectrum disorders (ASD), developmental delay and intellectual disability of unknown etiology. High-resolution arrays were utilized for the identification of copy number variations (CNVs) in 195 ASD patients of Greek origin (126 males, 69 females). CMA resulted in the detection of 65 CNVs, excluding the known polymorphic copy number polymorphisms also found in the Database of Genomic Variants, for 51/195 patients (26.1%). Parental DNA testing in 20/51 patients revealed that 17 CNVs were de novo, 6 paternal and 3 of maternal origin. The majority of the 65 CNVs were deletions (66.1%), of which 5 on the X-chromosome while the duplications, of which 7 on the X-chromosome, were rarer (22/65, 33.8%). Fifty-one CNVs from a total of 65, reported for our cohort of ASD patients, were of diagnostic significance and well described in the literature while 14 CNVs (8 losses, 6 gains) were characterized as variants of unknown significance and need further investigation. Among the 51 patients, 39 carried one CNV, 10 carried two CNVs and 2 carried three CNVs. The use of CMA, its clinical validity and utility was assessed.

Abstract
Background Rectal cancer surgery in the older population remains a highly controversial topic. The present study was designed to assess whether older patients had an increased risk for postoperative complications after rectal resection for malignancies. Methods Consecutive patients (n =627), who underwent rectal cancer resection at a single institution, were included in the study and analyzed retrospectively. Short-term complications were compared between patients ≥80 years (n =55) and <80 years (n =572). Additionally, predictive factors for postoperative complications were analyzed. Results The older aged group showed a significantly higher rate of co-morbidities compared to controls, in terms of cardiovascular and pulmonary diseases (P =0.002, P =0.006). In older patients, a Hartmann’s procedure and transanal endoscopic microsurgery (TEM) were performed most frequently (P <0.0001). The overall complication rate was 39% (n =244) (medical: n =59 (9%), surgical: n =185 (30%)), including 24 (44%) complications in the older aged group (medical: n =6 (11%), surgical: n =18 (33%)). Notably, the incidence of surgical and medical complications showed no significant difference between patients and controls (P =0.58, P =0.69). Neurological and cardiovascular disorders were associated with an increased risk for a eventful postoperative course in the older aged group (P =0.03, P =0.04). Conclusions Rectal cancer resection can be performed safely in selected older patients. Age itself should not be considered as a risk factor for postoperative complications.

Abstract
Chitotriosidase is a fully active chitinase produced and secreted by activated phagocytes. Plasma chitotriosidase activity is a well-established marker of total disease burden in Gaucher disease that has proved useful in monitoring the response to both enzyme replacement and substrate reduction therapies in patients with Gaucher disease. Increased chitotriosidase plasma activity has also been observed in several other lysosomal and non lysosomal disorders. Cystinosis, a rare multisystemic lysosomal storage disease, is characterized by the intralysosomal accumulation of free cystine in many cell types including phagocytes. We here report on plasma chitotriosidase activity in a child with nephropathic cystinosis. Increased plasma chitotriosidase activity (481 nmol/h per ml; normal range 0-150 units) was found on diagnosis and prior to the initiation of oral cysteamine (Cystagon) treatment. Serial estimations of plasma chitotriosidase activity showed that it correlated with leukocyte cystine content and decreased to 100 nmol/h per ml following 14 months' treatment. This novel observation suggests that cystinosis should be included in the differential diagnosis of disorders associated with increased plasma chitotriosidase activity. Furthermore, it suggests that serial estimations of plasma chitotriosidase activity could be of value in monitoring the response to oral cysteamine treatment in cystinosis.

Abstract
Neuroleptic Malignant Syndrome (NMS) is a rare but a potential lethal condition therefore it always represents a neurological emergency. Although NMS is considered mainly as idiosyncratic complication of antipsychotic medication, isolated reports show that the syndrome can rarely occur due to other causes such as, after abrupt withdrawal of anticholinergics and this was the case that is presented here. The syndrome continious to carry a high mortality rate and its basic management remains risk reduction, early diagnosis and supportive care. Thus, familiarity and vigilance to all known risk factors is considered essential for early diagnosis and intervention, and concequently for the reduction of morbidity and mortality of NMS.
