How we Provide Nutritional Treatment in Hospitalized Patients?

Background: In this study, we aimed to evaluate enteral nutrition (EN), parenteral nutrition (PN) and supplemental parenteral nutrition (SPN) in terms of achieving nutritional goals. Methods: Patients receiving either EN, PN, or SPN treatment followed up by the clinical nutrition team between January and December 2017 at the university research and training hospital were included in the study. Daily nutritional requirements were calculated according to the recommendations. Total energy intake during nutritional treatment (NT) and all metabolic, mechanical, technical complications of NT were recorded. Results: A total of 603 inpatients were included in the study. The nutritional goal was achieved in the majority of the SPN group patients (87.5%) statistically significant relation was found between the achievement of the target (or not) and PN access route (peripheral or central) (P < .001). However, none of the complications found statistically related to achieving the target, including gastrointestinal complications of EN (P = .46), metabolic complications of EN (P = .07), mechanical complications of EN (P = .79), metabolic complications of PN (P = .89), gastrointestinal complications in SPN group (P = .45), and metabolic complications in SPN group (P = .68).Conclusion: Nutritional goals could be achieved with SPN without increasing complications in the majority of patients. Commencement of SPN should be considered for positive outcomes in patients who failed to achieve desired nutritional outcomes.     

Fibroblast growth factor-19 levels in type 2 diabetic patients with metabolic syndrome

This study aimed to examine fibroblast growth factor-19 (FGF-19) in type 2 diabetic (T2DM) patients with metabolic syndrome (MetS) and to evaluate the relationship between FGF-19 and other cardiovascular risk factors, such as atherogenic index of plasma (AIP) and hsCRP. 26 T2DM patients with MetS and 12 healthy controls were enrolled in the study. Serum FGF-19 levels were measured by sandwich ELISA, and compared with other cardiovascular risk factors; lipid profile, AIP, glucose, HbA1c, and hsCRP. AIP was calculated as log (TG/HDL-c). The median (1-3.quartile) FGF-19 levels in T2DM patients with MetS and healthy controls were 122.90 (108.63-237.60) pg/ml and 293.45 (153.64-370.31) pg/ml, respectively (P=0.003). Patients were also grouped by body mass index (BMI) <30 kg/m(2) (n=13) and ≥30 kg/m(2) (n=13) with median (1-3.quartile) FGF-19 values 168.70 (113.54-275.77) pg/mL and 115.89 (97.94-200.40) pg/mL, respectively (P=0.007). Significant negative correlations were found between FGF-19 and BMI, triglyceride, log (TG/HDL-c), hsCRP, and HbA1c (r=-0.526, P=0.001; r=-0.327, P=0.05; r=-0.312, P=0.05; r=-0.435, P=0.006; r=-0.357, P=0.028, respectively). We showed that FGF-19 levels are low in T2DM patients with MetS. The negative relationship between FGF-19 and several known cardiovascular risk factors such as TG, log (TG/HDL-c), hsCRP and HbA1c in diabetic patients with MetS suggests that FGF-19 can be used as a contributing marker.     

Temporal overexpression of IL‐22 and Reg3γ differentially impacts the severity of experimental autoimmune encephalomyelitis

IL‐22 is an alpha‐helical cytokine which belongs to the IL‐10 family of cytokines. IL‐22 is produced by RORγt+ innate and adaptive lymphocytes, including ILC3, γδ T, iNKT, Th17 and Th22 cells and some granulocytes. IL‐22 receptor is expressed primarily by non‐haematopoietic cells. IL‐22 is critical for barrier immunity at the mucosal surfaces in the steady state and during infection. Although IL‐22 knockout mice were previously shown to develop experimental autoimmune encephalomyelitis (EAE), a murine model of multiple sclerosis (MS), how temporal IL‐22 manipulation in adult mice would affect EAE course has not been studied previously. In this study, we overexpressed IL‐22 via hydrodynamic gene delivery or blocked it via neutralizing antibodies in C57BL/6 mice to explore the therapeutic impact of IL‐22 modulation on the EAE course. IL‐22 overexpression significantly decreased EAE scores and demyelination, and reduced infiltration of IFN‐γ+IL‐17A+Th17 cells into the central nervous system (CNS). The neutralization of IL‐22 did not alter the EAE pathology significantly. We show that IL‐22‐mediated protection is independent of Reg3γ, an epithelial cell‐derived antimicrobial peptide induced by IL‐22. Thus, overexpression of Reg3γ significantly exacerbated EAE scores, demyelination and infiltration of IFN‐γ+IL‐17A+ and IL‐17A+GM‐CSF+Th17 cells to CNS. We also show that Reg3γ may inhibit IL‐2‐mediated STAT5 signalling and impair expansion of Treg cells in vivo and in vitro. Finally, Reg3γ overexpression dramatically impacted intestinal microbiota during EAE. Our results provide novel insight into the role of IL‐22 and IL‐22‐induced antimicrobial peptide Reg3γ in the pathogenesis of CNS inflammation in a murine model of MS.     

The effect of valsartan and nebivolol treatment on ADMA and pentraxin-3 levels in hypertensive patients

Long pentraxin 3 (PTX3) is a recently discovered multimeric inflammatory mediator that is structurally linked to short pentraxins, such as C-reactive protein (CRP) and serum amyloid P component. PTX3 is produced by a variety of tissues and cells, including vascular endothelial cells and macrophages. Because of its extrahepatic synthesis (in contrast to CRP), the PTX3 level is believed to be a true independent indicator of disease activity because PTX3 is produced at sites of inflammation and is intimately linked to endothelial dysfunction. PTX3 also has key functions in innate immunity and has been identified in atherosclerotic lesions. Previously, PTX3 was associated with myocyte damage in myocardial infarction (MI), mortality after MI, and unstable angina. Because PTX3 release is likely a specific response to vascular damage, PTX3 levels may provide more explicit information on development and progression of atherosclerosis than nonspecific markers like CRP and interleukin-6. Asymmetric dimethylarginine (ADMA) is a naturally occurring component of human blood plasma. More than one decade ago ADMA was first reported to exert biological effects by inhibiting nitric oxide synthesis. Many researchers today agree that ADMA may play a prominent role in the pathogenesis and in the progression of cardiovascular diseases. In this study PTX3 and ADMA levels investigated of valsartan and nebivolol's effect on newly diagnosed hypertensive patients.     

The in vitro hepatic metabolism of 1-phenyl-2-(2-benzothiazolinone-3-yl)ethanone and their reduced derivatives.

The in vitro hepatic microsomal metabolism of 1-phenyl-2-(2-benzothiazolinone-3-yl)ethanone (I) and (+/-)-1-Phenyl-2-(2-benzothiazolinone-3-yl)ethanol (II) was studied using both rat microsomal preparations and soluble fractions fortified with NADPH. These two substrates and their potential dealkylation metabolite 2-benzothiazolinone were synthesized and their structures were elucidated by spectral methods. The results showed that (I) was metabolised to (II), the corresponding alcohol by reduction. More alcohol metabolite was observed with microsomes than those obtained with the soluble fractions. No dealkylation of (I) was observed in the experiments using both microsomes and soluble fractions. (II) was metabolised to (I), the corresponding ketone by oxidation. However, compared to the metabolism of (I), more ketone metabolite was observed with soluble fractions than microsomes. (II) was also dealkylated to (III) with only soluble fractions but no dealkylated metabolites were found in the microsomes. In addition, a common unknown metabolite was observed with each substrates.     

Comparing Clinicopathologic and Radiographic Findings Between TT-UMP,Classical, and Non-Encapsulated Follicular Variants of Papillary Thyroid Carcinomas

Thyroid tumors of uncertain malignant potential (TT-UMP) comprise an accepted subgroup of follicular-patterned thyroid tumors for which benignancy or malignancy cannot be precisely assessed. We aimed to evaluate the demographic characteristics, ultrasound (US) findings, and cytological results of patients with TT-UMP and compare these findings to a classical variant of papillary thyroid carcinoma (CV-PTC) and non-encapsulated follicular variant of PTC (NEFV-PTC) patients; we also evaluated the immunohistochemical characteristics of patients with TT-UMP. Twenty-four patients with TT-UMP, 672 with CV-PTC, and 132 with NEFV-PTC were included in the study. Mean longitudinal nodule size and median nodule volume were higher in the TT-UMP group than in the CV-PTC and NEFV-PTC groups (p?<?0.001 and p?<?0.001 for CV-PTC; p?<?0.001 and p?=?0.008 for NEFV-PTC). The presence of halo and peripheral vascularization was observed more frequently in the TT-UMP group than in the CV-PTC group (p?=?0.002 and p?=?0.024). Benign and follicular neoplasm/suspicious for follicular neoplasm cytological results were higher in the TT-UMP group than in the CV-PTC group (p?=?0.030 and p?=?0.001). US findings were similar between TT-UMP and NEFV-PTC groups (all, p?>?0.05). However, none of the patients with TT-UMP were called malignant; 105 patients (31.2 %) of CV-PTC and 11 patients (9.5 %) of NEFV-PTC (infiltrative FV) were classified as malignant cytologically. Tumor size was higher in the TT-UMP group than in the CV-PTC and NEFV-PTC groups (p?<?0.001 and p?=?0.006). In the TT-UMP group, positive expression of HBME-1, CK-19, and Gal-3 was found in 50, 33.3, and 25 % of patients, respectively. This study demonstrated that none of the TT-UMP patients were evaluated as malignant in preoperative cytology. However, patients with TT-UMP had higher nodule and tumor sizes than CV-PTC and NEFV-PTC patients; US features were similar between NEFV-PTC and TT-UMP patients.     

Cytopathologic differential diagnosis of malignant mesothelioma, adenocarcinoma and reactive mesothelial cells: A logistic regression analysis

Distinguishing malignant mesothelioma, adenocarcinoma and reactive mesothelial proliferation in both cytologic and surgical pathologic specimens is often a diagnostic challenge. Conventional cytomorphologic assessment is an important step in the differential diagnosis of these entities.The pleural effusion cytologies from 40 cases of malignant mesothelioma, 40 cases of adenocarcinoma and 30 cases of reactive mesothelial proliferation diagnosed between 1997 and 2007 were reviewed. Twenty-seven cytologic features which are regarded as useful in the differential diagnosis of mesothelioma, adenocarcinoma and benign mesothelial proliferation were assessed. These cytologic features were subjected to a stepwise logistic regression analysis. Three features were selected to distinguish malignant mesothelioma from adenocarcinoma: giant atypical mesothelial cell (P = 0.0001), nuclear pleomorphism (P = 0.0001) and acinar structures (P = 0.0001), the latter two being characteristics of adenocarcinoma. The variables selected to differentiate malignant mesothelioma from reactive mesothelial cells were: cell ball formation (P = 0.0001), cell in cell engulfment (P = 0.0001) and monolayer cell groups (P = 0.0001), the latter being a feature of benign mesothelial proliferation. When these selected variables were subjected to a stepwise logistic regression analysis, the logistic model correctly predicted 90% of cases of benign mesothelial proliferation versus 97.5% of malignant mesothelioma and 92.5% of malignant mesothelioma versus 92.5% of adenocarcinoma.Conventional cytomorphologic assessment is the first step to establish an accurate diagnosis in pleural effusions. Several cytologic features have predictive value to separate malignant mesothelioma from adenocarcinoma and reactive mesothelial proliferation.

Primary adenocarcinoma of the epididymis: Case report

Primary epididymal malignancies are uncommon and usually benign. Benign paratesticular tumors are most commonly adenomatoid, while the most common malignant paratesticular tumors are rhabdomyosarcomas. Approximately 25% of all epididymal tumors are malignant, and of the benign tumors, 60% to 78% are adenomatoid tumors. According to a recent MEDLINE search using epididymis and adenocarcinoma as key words, reports of a primary epididymal adenocarcinoma are extremely rare with only 23 cases in the literature. We report a case of epididymal adenocarcinoma with clinical follow up and metastatic natural history of this rare malignancy. This revised version was published online in August 2006 with corrections to the Cover Date.     

Pediatric diffuse intrinsic pontine glioma patients from a single center

Background

The prognosis of children with diffuse intrinsic pontine gliomas (DIPG) is dismal. This study aims to evaluate the characteristics and treatment outcome of children with DIPG in a single center.

Methods

We reviewed the outcome of children with DIPG treated at the Oncology Institute of Istanbul University from February 1999 to May 2012.

Results

Fifty children (26 female, 24 male) with the median age of 7 years were analyzed. The median duration of symptoms was 30 days. All patients received radiotherapy (RT). Before the year 2000, 12 patients received only RT. Thirty-eight had concomitant and/or adjuvant chemotherapy with RT. Between 2000 and 2004, 17 patients received cis-platinum or vincristine as sensitizers during RT and CCNU + vincristine combination after RT. Since 2004, 21 patients received temozolomide (TMZ) concomitantly during RT and as adjuvant chemotherapy after RT. The median survival time of all patients was 13 months (1–160 months). Patients receiving RT + TMZ had a significantly higher overall survival than patients with only RT (p?=?0.018). Patients receiving RT + chemotherapy other than TMZ also had a significantly higher overall survival than patients receiving only RT (p?=?0.013). Patients receiving RT + TMZ + and chemotherapy other than TMZ had a significantly higher survival than patients receiving only RT (p?=?0.005).

Conclusion

In our series, patients receiving RT + TMZ and also patients receiving RT + chemotherapy other than TMZ had a significantly higher overall survival than patients treated with only RT. Hence, administering chemotherapy during and after RT seems to prolong survival in some DIPG patients.
