Substantial advances have been made recently in the pathobiology of pituitary tumors. Similar to many other endocrine tumors, over the last few years we have recognized the role of germline and somatic mutations in a number of syndromic or non-syndromic conditions with pituitary tumor predisposition. These include the identification of novel germline variants in patients with familial or simplex pituitary tumors and establishment of novel somatic variants identified through next generation sequencing. Advanced techniques have allowed the exploration of epigenetic mechanisms mediated through DNA methylation, histone modifications and non-coding RNAs, such as microRNA, long noncoding RNAs and circular RNAs. These mechanisms can influence tumor formation, growth and invasion. While genetic and epigenetic mechanisms often disrupt similar pathways, such as cell cycle regulation, in pituitary tumors there is little overlap between genes altered by germline, somatic and epigenetic mechanisms. The interplay between these complex mechanisms driving tumorigenesis are best studied in the emerging multi-omics studies. Here, we summarize insights from the recent developments in the regulation of pituitary tumorigenesis. © Endocrine Society 2020.With agriculture rapidly becoming a data driven field it is imperative to extract useful information from large data collections to optimize the production systems. We compared the efficacy of regression (linear regression or generalized linear regression for continuous or categorical outcomes, respectively), random forests (RF) and multilayer neural networks (NN) to predict beef carcass weight (CW), age when finished (AS), fat deposition (FD), and carcass quality (CQ). The data analyzed contained information on over 4 million beef cattle from 5,204 farms, corresponding to 4.3% of Brazil's national production between 2014-2016. Explanatory variables were integrated from different data sources and encompassed animal traits, participation in a technical advising program, nutritional products sold to farms, economic variables related to beef production, month when finished, soil fertility, and climate in the location in which animals were raised. The training set was composed of information collected in 2014 and allocation of resources at all levels of the production chain, rendering animal production more sustainable. Despite beef cattle production being a complex system, this analysis shows that by integrating different sources of data it is possible to forecast meat production and quality at the national level with moderate-high levels of accuracy. © The Author(s) 2020.

In Exp. 1, ten Duroc × Landrace × Yorkshire barrows (initial BW 48.7 kg) were allotted to a 3-period switchback design with 5 experimental diets and 2 replicate pigs per diet in each period. Diets were high-CP (HP, 18% CP), moderate low-CP (MLP, 15% CP), very low-CP (VLP, 12% CP), and MLP and VLP with 0.1% NCG supplementation. Feces and urine were collected from d 6 to 11 after a 5-d adaptation period. The DE, ME and ATTD of GE, OM, CP, NDF, ADF and P decreased (P less then 0.01) with reduction of dietary CP, but no effect of dietary treatments on pig daily N retention was detected. The NCG supplementation increased (P less then 0.01) DE and ATTD of ADF of VLP diet. In Exp. 2, ten jejunal-cannulated Duroc × Landrace × Yorkshire barrows (initial(P less then 0.01) the AID of CP and ileal digestibility of Arg, His, Leu, Phe, Val, Ser and Tyr. In conclusion, reducing dietary CP level decreased nutrient digestibility, but improved the efficiency of dietary N utilization and reduced N emission. Moderate reduction of dietary CP level had a minimal effect on nutrient digestibility and digestive enzyme activity. Additionally, NCG supplementation plays beneficial effect on nutrient digestion only if the dietary CP level is extremely lowered. © The Author(s) 2020.

We investigated the relationship between mucosal healing defined by modified PICaSSO (Paddington International Virtual ChromoendoScopy ScOre), Mayo Endoscopic Score (MES) and probe-based confocal laser endomicroscopy (pCLE) with histological indices in UC. METHODS A prospective study enrolling 82 UC patients (M 66%) was conducted. High definition (HD) colonoscopy was performed to evaluate the activity of the disease with MES assessed with High Definition (HD-MES) and modified PICaSSO and targeted biopsies were taken; pCLE was then performed. Receiver Operating Characteristic (ROC) curves were plotted to determine the best thresholds for modified PICaSSO and pCLE scores that predicted histological healing according to the Robarts Histopathology Index (RHI) and ECAP 'Extension, Chronicity, Activity, Plus' histology score. RESULTS A modified PICaSSO of ≤4 predicted histological healing at RHI ≤3, with sensitivity, specificity, accuracy and area under the ROC curve (AUROC) of 89.8%, 95.7%, 91.5% and 95.9% respectively. The sensitivity, specificity, accuracy and AUROC of HD-MES to predict histological healing by RHI were 81.4%, 95.7, 85.4% and 92.1%, respectively. A pCLE ≤10 predicted histological healing with sensitivity 94.9%, specificity 91.3%, accuracy of 93.9% and AUROC of 96.5%. An ECAP of ≤10 was predicted by modified PICaSSO ≤4 with accuracy of 91.5% and AUROC of 95.9%. CONCLUSION Histological healing by RHI and ECAP is accurately predicted by HD-MES and modified virtual electronic Chromoendoscopy PICaSSO,endoscopic score ; and the use of pCLE did not improve the accuracy any further. https://www.selleckchem.com/products/LY2603618-IC-83.html © The Author(s) 2020.

BACKGROUND Generally, hemangiomas do not require surgical intervention; however, cases of large hemangiomas, potentially involving the throat and trachea, necessitate surgical therapy. Here, we present a case of hypopharyngeal hemangioma in an adult that was successfully treated with neodymium-doped yttrium aluminum garnet (Nd-YAG) laser. CASE SUMMARY Laryngoscopic examination of a 61-year-old man demonstrated the presence of a large, submucosal vascular lesion that extended into the epiglottis, left arytenoid cartilage, lateral to the aryepiglottic fold, and pyriform sinus. The lesion was resected and photocoagulated with limited hemorrhage using Nd YAG laser. The hypopharyngeal hemangioma was completely excised. https://www.selleckchem.com/products/sar439859.html The patient showed no recurrence of hypopharyngeal hemangioma during the 1.5-year follow-up period. CONCLUSION Laser therapy is one of the effective tools for treating hemangiomas with rapid, uncontrolled growth or in functional areas, with few side effects and complications. The present case of a male patient with a large hypopharyngeal hemangioma, treated with YAG laser, demonstrates the efficacy of laser photocoagulation in treating cases of hemangiomas, without the risk of bleeding or airway obstruction. The favorable postoperative outcomes demonstrated by our patient with Nd YAG laser therapy indicate its consideration in the therapy of similar cases. ©The Author(s) 2020.

Reports of thrombocytopenic toxicity of NOACs are limited. In this report, we present a case of thrombocytopenia likely induced by rivaroxaban, which is an extremely rare adverse drug reaction. CASE SUMMARY A 70-year-old man presented to the cardiovascular department with a chief complaint of intermittent chest tightness and dyspnea over the last five years. Vital signs were within normal limits at presentation, with a heart rate of 65 beats/min, blood pressure of 138/78 mmHg, respiratory rate of 19 breaths/min, and temperature of 36.1°C. Laboratory tests indicated a platelet count of 163 × 109/L on admission. Anticoagulant therapy with rivaroxaban, a NOAC, was started on the second day of hospitalization. The platelet count decreased to 30 × 109/L on hospital day 11 and then 10 × 109/L on day 12. Rivaroxaban was stopped on day 13 when the platelet count decreased to 5 × 109/L. After the cessation of rivaroxaban, the platelet count returned to normal. The patient was diagnosed with thrombocytopenia, which was likely induced by rivaroxaban. The incidence of thrombocytopenic toxicity of NOACs is extremely low. CONCLUSION Thrombocytopenia during anticoagulation therapy may be associated with a high risk of life-threatening bleeding. For elderly patients, changes in platelet count should be carefully monitored at the beginning of NOAC treatment, and we should be on the alert for bleeding events as well. ©The Author(s) 2020.

Herein, we report a case of oxcarbazepine-induced lower leg weakness in a patient with trigeminal neuralgia and summarize the diagnosis, treatment, and changes of clinical symptoms. CASE SUMMARY A 78-year-old male with a history of lumbar spinal stenosis was admitted to the hospital after he experienced lancinating pain around his right cheek, eyes, and lip, and was diagnosed with trigeminal neuralgia at the right maxillary and mandibular branch. He was prescribed oxcarbazepine (600 mg/d), milnacipran (25 mg/d), and oxycodone/naloxone (20 mg/10 mg/d) for four years. Four years later, the patient experienced symptoms associated with spinal stenosis, including pain in the lower extremities and unsteady gait. His serum sodium level was 127 mmol/L. Assuming oxcarbazepine to be the cause of the hyponatremia, oxcarbazepine administration was put on hold and the patient was switched to topiramate. At subsequent visit, the patient's serum sodium level had normalized to 143 mmol/L and his unsteady gait had improved. CONCLUSION Oxcarbazepine-induced hyponatremia may cause lower extremity weakness and unsteady gait, which should be differentiated from those caused by spinal stenosis. ©The Author(s) 2020.

Graftectomy is widely considered the safest option. Due to the rarity of the disease and the substantial risk of fatal consequences, experience with conservative strategies is limited. To date, only a few reports on surgical repair have been published. We describe a case of true MA successfully managed by aneurysm resection and arterial re-anastomosis. CASE SUMMARY An 18-year-old gentleman, on post-operative day 70 after deceased donor kidney transplantation, presented with malaise, low urinary output, and worsening renal function. Screening organ preservation fluid cultures, collected at the time of surgery, were positive for Candida albicans. Doppler ultrasound and contrast-enhanced computer tomography showed a 4-cm-sized, saccular aneurysm of the iuxta-anastomotic segment of the allograft artery, suspicious for MA. The lesion was wide-necked and extended to the distal bifurcation of the main arterial branch, thus preventing endovascular stenting and embolization. After multidisciplinary discussion, the patient underwent surgical exploration, aneurysm excision, and re-anastomosis between the stump of the allograft artery and the internal iliac artery. The procedure was uneventful. Histology and microbiology evaluation of the surgical specimen confirmed the diagnosis of MA caused by Candida infection. Three years after the operation, the patient is doing very well with excellent allograft function and no signs of recurrent disease. CONCLUSION Surgical repair represents a feasible option in carefully selected patients with allograft artery MA. Anti-fungal prophylaxis is advised when preservation fluid cultures are positive. ©The Author(s) 2020. Published by Baishideng Publishing Group Inc. All rights reserved.
