Abstract
SummaryIncreased plasma levels of β-thromboglobulin (βTG) and fibrinopeptide A (FPA), markers of platelet release and thrombin generation respectively, were measured in normal women, women taking oral contraceptives, normal pregnancy and pregnant women with hypertension or pre-eclampsia. No significant increases in βTG or FPA were found in women taking oral contraceptives. Significantly increased concentrations of βTG, but not FPA, were found in normal pregnant women in the second and third trimester of pregnancy when compared with nonpregnant age-matched controls. In eleven women with pregnancy hypertension and thirteen women with pre-eclampsia significantly elevated levels of both βTG and FPA were found when compared with age, parity and gestation-matched pregnant controls. Although the mean value for both βTG and FPA in the group with pre-eclampsia was higher than the group with pregnancy hypertension, the difference was not statistically significant. These findings provide additional evidence that pre-eclampsia and pregnancy hypertension are associated with activation of the coagulation system and the platelet release reaction.

Abstract
INTRODUCTION Pre-eclampsia is a pregnancy-induced disorder that complicates approximately 5-7% of pregnancies. It is the leading cause of maternal and foetal morbidity and mortality worldwide. AIM To determine the role of serum neurokinin-B level in the pathophysiology of pre-eclampsia. METHODS This was a case-control study. A total of 80 pregnant women in their third trimester of pregnancy were included in the study. They were divided into two groups (40 pre-eclamptic and 40 normotensive) according to the presence or absence of clinical parameters of pre-eclampsia. Serum level of neurokinin-B was measured with ELISA. RESULTS Maternal age, weight, BMI, pulse, systolic BP and diastolic BP were statistically higher in the pre-eclampsia group compared to the normotensive group (P < 0.0001). Moreover, statistically higher levels were observed for neurokinin-B in the normotensive group as compared to the pre-eclamptic group. The mean value of neurokinin-B was 83.50 ng/L in the pre-eclamptic group compared to 111.5 ng/L in the normotensive group (P = 0.006). CONCLUSION Higher levels of serum neurokinin-B were observed in the normotensive pregnant females as compared to the pre-eclamptic females. Thus, apparently, it seems that serum neurokinin-B plays no role in the pathophysiology of pre-eclampsia, and further large multicentre prospective studies may be required to ascertain its role.

Abstract
Prolonged stressor exposure in adolescence enhances the risk of developing stress-sensitive mental illnesses, including posttraumatic stress disorder (PTSD), for many years following exposure cessation, but the biological underpinnings of this long-term vulnerability are unknown. We show that severe stressor exposure increased circulating levels of the hormone acyl-ghrelin in adolescent rats for at least 130 days and in adolescent humans for at least 4.5 years. Using a rodent model of longitudinal PTSD vulnerability in which rodents with a history of stressor exposure during adolescence display enhanced fear in response to fear conditioning administered weeks after stressor exposure ends, we show that systemic delivery of a ghrelin receptor antagonist for 4 weeks surrounding stressor exposure (2 weeks during and 2 weeks following) prevented stress-enhanced fear memory. These data suggest that protracted exposure to elevated acyl-ghrelin levels mediates a persistent vulnerability to stress-enhanced fear after stressor exposure ends.

Abstract
INTRODUCTION Cognitive training is an important training modality which allows the user to rehearse a procedure without physically carrying it out. This has led to recent interests to incorporate cognitive training within surgical education but research is currently limited. The use of cognitive training in surgery is not clear-cut and so this study aimed to determine whether, relative to a control condition, the use of cognitive training improves technical surgical skills on a ureteroscopy simulator, and if so whether one cognitive training method is superior. METHODS This prospective, comparative study recruited 59 medical students and randomised them to one of three groups: control- simulation training only (n=20), flashcards cognitive training group (n=20) or mental imagery cognitive training group (n=19). All participants completed three tasks at baseline on the URO Mentor simulator followed by the cognitive intervention if randomised to receive it. Participants then returned to perform an assessment task on the simulator. Outcome measures from the URO Mentor performance report was used for analysis and a quantitative survey was given to all participants to assess usefulness of training received. RESULTS This study showed cognitive training to have minimal effects on technical skills of participants. The mental imagery group had fewer laser misfires in the assessment task when compared to both control and flashcards group (P=.017, P=.036, respectively). The flashcards group rated their preparation to be most useful when compared to control (P=.0125). Other parameters analysed between the groups did not reach statistical significance. Cognitive training was found to be feasible and cost effective when carried out in addition to simulation training. CONCLUSION This study has shown that the role of cognitive training within acquisition of surgical skills is minimal and that no form of cognitive training was superior to another. Further research needs to be done to evaluate other ways of performing cognitive training.

Abstract
Carbapenems, a more recent β-lactam class, represent a unique anti-tuberculosis option, as emerging evidence demonstrates that they target the Mycobacterium tuberculosis cell wall and β-lactamase. This provides a potentially new agent against M. tuberculosis, in particular for multidrug-resistant (MDR) and extensively drug-resistant (XDR) tuberculosis (TB), where options are limited. In this review, we examine the current evidence on the activity of carbapenems against M. tuberculosis. The predominance of work is in vitro, and suggests that carbapenems kill M. tuberculosis at least in the active phase, with possible greater potency with the addition of a β-lactamase inhibitor. The few in vivo and clinical studies suggest that there are benefits and that they are generally tolerated, although the variability in duration, dosing, and background regimen and lack of pharmacokinetic analyses limit interpretation of efficacy. We outline further areas of research to better understand the role of carbapenems to add a needed new agent to the treatment of MDR- and XDR-TB.

Abstract
41 Background: Solid organ transplant recipients have been excluded from Checkpoint inhibitors (CPI) clinical trials because of the concern of allo-immunity and possible organ rejection. Methods: We searched 5 databases through September 2017. Studies describing the use of CPI to treat cancer in solid organ transplant Patients (pts), and provided detailed description of each case were included. Results: Sixteen publications met inclusion criteria, reporting on 19 cases. Median age of pts was 59 (14-77) yrs and 74% were male. Cancer types included melanoma (n=11), cutaneous squamous cell carcinoma (ca) (n=3), non-small cell lung ca and hepatocellular ca (n=2 each), and duodenal ca (n=1). Median time to start CPI after organ transplant was 11 (1-25) yrs. Nivolumab (nivo) was used in 53%, ipilimumab (ipi) in 26%, and pembrolizumab (pem) in 21%. Most pts were maintained on low dose prednisone (≤ 10 mg), mTOR inhibitors, and other immunosuppressives prior to initiating CPI. Graft rejection occurred in 10 of 19 pts (7/12 kidney, 2/5 liver, and 1/2 heart transplants), 90% after receiving anti PD-1, and CPI was discontinued. Median time to rejection was 21 (5-60) days, and obtained biopsies were suggestive of a T-cell mediated rejection process. Only a cardiac transplant recipient with a bioposy proven cellular rejection after nivo, had improved ejection fraction after pulse steroids. Aside from rejection no other immune related adverse events (irAEs) reported. Nivo re-challenge was recommended for a kidney recipient 12 weeks after the rejection process, and the pt had partial tumor response but remained on hemodialysis. Of the 9 pts who had no rejection, 4 had irAEs (hepatitis, colitis, pneumonitis, and dermatitis), including 3 who required high-dose steroids with subsequent improvement, and the remaining 5 pts did not experience any irAEs. Clinical benefit rate was 57% of all pts. Two pts with liver transplants died within 1 month of nivo treatment secondary to acute liver rejection, and 2 others died because of progressive cancer. Conclusions: CPI seem to be associated with high rate of rejection. Multi-institutional collaborative studies are warranted to enhance our understanding of the pathogenesis and plan optiomal therapy that maintain graft tolerance without dampening antitumor clinical benefits.

Abstract
The American Society of Pediatric Hematology/Oncology (ASPHO) solicited information from division directors and fellowship training program directors to capture pediatric hematology/oncology (PHO) specific workforce data of 6 years (2010-2015), in response to an increase in graduating fellows during that time. Observations included a stable number of physicians and advanced practice providers (APPs) in clinical PHO, an increased proportion of APPs hired compared to physicians, and an increase in training-level first career positions. Rapid changes in the models of PHO care have significant implications to current and future trainees and require continued analysis to understand the evolving discipline of PHO.

Abstract
BACKGROUND Cancer immunotherapy with checkpoint inhibitors (CPIs) is associated with frequent immune-related adverse events (irAEs) and is often not recommended for patients with concomitant autoimmune disease. PURPOSE To summarize the evidence on adverse events associated with CPIs in patients with cancer and preexisting autoimmune disease. DATA SOURCES MEDLINE, EMBASE, Web of Science, PubMed ePubs, and the Cochrane Central Register of Controlled Trials through September 2017 with no language restrictions. STUDY SELECTION Original case reports, case series, and observational studies describing patients with cancer and autoimmune disease who were receiving CPIs. DATA EXTRACTION 2 reviewers independently extracted data and assessed the quality of reporting. DATA SYNTHESIS 123 patients in 49 publications were identified; 92 (75%) had exacerbation of preexisting autoimmune disease, irAEs, or both. No differences in adverse events were observed in patients with active versus inactive disease. Patients receiving immunosuppressive therapy at initiation of CPI therapy seemed to have fewer adverse events than those not receiving treatment. Most flares and irAEs were managed with corticosteroids; 16% required other immunosuppressive therapies. Adverse events improved in more than half of patients without discontinuation of CPI therapy. Three patients died of adverse events. LIMITATIONS The quality and quantity of data were limited. Case reports typically describe unique manifestations and are not generalizable to the population at large. Because there were no prospective observational studies, incidence could not be determined. CONCLUSION Flares and irAEs in patients with autoimmune disease who are receiving CPIs can often be managed without discontinuing therapy, although some events may be severe and fatal. Prospective longitudinal studies are needed to establish incidence of adverse events and evaluate risk-benefit ratios and patient preferences in this population.

Abstract
Oxygen therapy, usually administered by a facemask or nasal cannulae, is the current default treatment of respiratory failure. Since respiration entails intake of oxygen and release of carbon dioxide from tissues as waste product, the notion of administering carbon dioxide in respiratory failure appears counter-intuitive. However, carbon dioxide stimulates the chemosensitive area of the medulla, known as the central respiratory chemoreceptor, which activates the respiratory groups of neurones in the brainstem and stimulates inspiration thereby initiating oxygen intake during normal breathing. This vital initiation of normal breathing is via a reduction in the pH of the cerebrospinal fluid and the medullary interstitial fluid. We hypothesise that in cases of type I respiratory failure in which the PaCO2 is low, administration of carbon dioxide by inhalation would stimulate the respiratory groups of brainstem neurones and facilitate breathing, which would be of therapeutic value. Preliminary clinical evidence in favour of this hypothesis is presented and we recommend that a formal randomised study be carried out.

Abstract
BACKGROUND Primary analysis of the double-blind, phase III Efficacy of XL184 (Cabozantinib) in Advanced Medullary Thyroid Cancer (EXAM) trial demonstrated significant improvement in progression-free survival with cabozantinib versus placebo in patients with progressive medullary thyroid cancer (MTC). Final analysis of overall survival (OS), a key secondary endpoint, was carried out after long-term follow-up. PATIENTS AND METHODS EXAM compared cabozantinib with placebo in 330 patients with documented radiographic progression of metastatic MTC. Patients were randomized (2:1) to cabozantinib (140 mg/day) or placebo. Final OS and updated safety data are reported. RESULTS Minimum follow-up was 42 months. Kaplan-Meier analysis showed a 5.5-month increase in median OS with cabozantinib versus placebo (26.6 versus 21.1 months) although the difference did not reach statistical significance [stratified hazard ratio (HR), 0.85; 95% confidence interval (CI), 0.64-1.12; P = 0.24]. In an exploratory assessment of OS, progression-free survival, and objective response rate, cabozantinib appeared to have a larger treatment effect in patients with RET M918T mutation-positive tumors compared with patients not harboring this mutation. For patients with RET M918T-positive disease, median OS was 44.3 months for cabozantinib versus 18.9 months for placebo [HR, 0.60; 95% CI, 0.38-0.94; P = 0.03 (not adjusted for multiple subgroup analyses)], with corresponding values of 20.2 versus 21.5 months (HR, 1.12; 95% CI, 0.70-1.82; P = 0.63) in the RET M918T-negative subgroup. Median treatment duration was 10.8 months with cabozantinib and 3.4 months with placebo. The safety profile for cabozantinib remained consistent with that of the primary analysis. CONCLUSION The secondary end point was not met in this final OS analysis from the trial of cabozantinib in patients with metastatic, radiographically progressive MTC. A statistically nonsignificant increase in OS was observed for cabozantinib compared with placebo. Exploratory analyses suggest that patients with RET M918T-positive tumors may experience a greater treatment benefit with cabozantinib. TRIAL REGISTRATION NUMBER NCT00704730.

Abstract
<p>In this study the effect of temperature and humidity on electrical properties of organic orange dye (OD) complex with vinyl-ethynyl-trimethyl-piperidole (VETP) have been examined. Thin films of OD (C<sub>17</sub>H<sub>17</sub>N<sub>5</sub>O<sub>2</sub>) and VETP (C<sub>12</sub>H<sub>19</sub>NO) complex were deposited from 10 wt.% (5 wt.% of each matter) solution in mixture of distilled water (80%) and spirit. The films were grown at room temperature under normal gravity conditions, <em>i.e.</em>, 1 g and in a spin coater at an angular speed of 300 RPM. The Cu/OD-VETP/Cu surface type samples were fabricated and their low frequency (10 Hz) AC electric characteristics were evaluated for the temperature range 30-95 °C at ambient humidity of 45-80%. It was observed that at normal conditions the conductivity of the samples is temperature dependent and shows semi-conductive behavior with activation energy of 0.55 eV. It was found that with increase in humidity the resistance of the samples decreases and at humidity values equal to 60-70% the irreversible transition from semi-conductive to conductive state takes place. It is supposed that in the former state the conductive matrix is formed due to incorporation of the water molecules into OD-VETP complex.</p>

Abstract
BACKGROUND AND PURPOSE New deep brain stimulation leads with electrode contacts that are split along their circumference allow steering of the electrical field in a predefined direction. However, imaging-assisted directional stimulation requires detailed knowledge of the exact orientation of the electrode array. The purpose of this study was to evaluate whether this information can be obtained by rotational 3D fluoroscopy. MATERIALS AND METHODS Two directional leads were inserted into a 3D-printed plaster skull filled with gelatin. The torsion of the lead tip versus the lead at the burr-hole level was investigated. Then, 3 blinded raters evaluated 12 3D fluoroscopies with random lead orientations. They determined the lead orientation considering the x-ray marker only and considering the overlap of the gaps between the contact segments. Intraclass correlation coefficients and an extended version of the Bland-Altman plot were used to determine interrater reliability and agreement of the measurements of the different raters. RESULTS Electrode torsion of up to 35° could be demonstrated. Evaluation of the lead rotation considering the x-ray marker only revealed limits of agreement of ±9.37° and an intraclass correlation coefficient of 0.9975. In addition, taking into account the lines resulting from overlapping of the gaps between the electrode segments, the limits of agreement to the mean were ±2.44° and an intraclass correlation coefficient of 0.9998. CONCLUSIONS In directional deep brain stimulation systems, rotational 3D fluoroscopy combined with the described evaluation method allows for determining the exact orientation of the leads, enabling the full potential of imaging-assisted personalized programming.

Abstract
BACKGROUND Faecal microbiota transplantation (FMT) has become routine in managing recurrent C. difficile infection (CDI) refractory to antibiotics. AIM To compare clinical response and improvements in colonic microbiota diversity in subjects with recurrent CDI using different donor product. METHODS Seventy-two subjects with ≥3 bouts of CDI were randomised in a double-blind study to receive fresh, frozen or lyophilised FMT product via colonoscopy from 50 g of stool per treatment from eight healthy donors. Recipients provided stools pre- and 7, 14 and 30 days post-FMT for C. difficile toxin and, in a subset, microbiome composition by 16S rRNA gene profiling. RESULTS Overall resolution of CDI was 87% during 2 months of follow-up after FMT. Stool samples before FMT had significantly decreased bacterial diversity with a high proportion of Proteobacteria compared to donors. Cure rates were highest for the group receiving fresh product seen in 25/25 (100%), lowest for the lyophilised product 16/23 (78%; P = 0.022 vs. fresh and 0.255 vs. frozen) and intermediate for frozen product 20/24 (P = 0.233 vs. fresh). Microbial diversity was reconstituted by day 7 in the subjects receiving fresh or frozen product. Improvement in diversity was seen by day 7 in those randomised to lyophilised material with reconstitution by 30 days. CONCLUSIONS Comparative efficacy in faecal microbiota transplantation was observed in subjects receiving fresh or frozen faecal product from the same donors. The lyophilised product had a slightly lowered efficacy compared with fresh product, but it resembled other treatments in microbial restoration 1 month after faecal microbiota transplantation.

Abstract
Abstract
Background
Patients (pts) receiving chemotherapy for breast cancer experience toxicities impacting short and long-term quality of life (QOL). Within I-SPY 2, a trial adaptively randomizing stage II/III breast cancer pts to neoadjuvant chemotherapy +/- an investigational agent, we are collecting pt reported outcome (PRO) data to understand the impact of investigational agents on QOL. This PRO sub-study provides a unique opportunity to study QOL longitudinally and explore how pt and tumor characteristics, exposure to investigational therapies, and surgical outcome impact QOL.
Methods
Pts enrolled in this trial receive paclitaxel (T) +/- an investigational agent for 12 weeks followed by 4 cycles of doxorubicin and cyclophosphamide (AC). Surveys include the EORTC QLQ-C30 and BR-23, and PROMIS measures for QOL metrics including but not limited to physical function (PF), anxiety, and depression. Surveys are administered pre-chemotherapy to 2 years post-surgery. PF data from the EORTC and PROMIS instruments was analyzed for 238 pts at 5 sites (UCSF, UCSD, U of Pennsylvania, U of Minnesota, and Swedish Cancer Center). 48 pts completed baseline, inter-regimen (between T and AC), pre-operative and post-surgery surveys. Of the 48 pts 32 completed a 6-month follow up (FUP) and 31 completed a 1-year FUP survey. A linear mixed effect model, adjusting for HER2 status and treatment type was used to evaluate changes in PF over time. Sample size is small and statistics are descriptive rather than inferential.
Results
Median age of pts in this analysis was 50 (range 27-72).
Table 1 shows PROMIS & EORTC PF scores in this cohort.Time Point PROMISEORTC nMeanSEMeanSEPre-TreatmentAll4852.51.092.02.0 HER2+1553.51.594.12.2 HER2-3352.11.391.12.8Inter-RegimenAll4845.51.282.22.7 HER2+1548.62.384.44.2 HER2-3344.11.381.23.4Pre-SurgeryAll4843.91.179.42.3 HER2+1545.12.275.34.1 HER2-3343.41.381.32.86-Month FUPAll3248.11.487.41.9 HER2+1247.52.285.03.3 HER2-2048.41.888.92.41 Year FUPAll3148.91.488.43.1 HER2+949.12.988.95.4 HER2-2248.81.788.33.8
At baseline, mean PROMIS PF scores were higher than the US average (mean = 50) but declined as expected throughout treatment. HER2+ patients experienced a similar degree of recovery as HER2- pts post-surgery despite adjuvant treatment with Herceptin. Analysis of post-operative PROMIS PF indicated an average score within the U.S. general population (mean =50) but did not return to higher functioning seen at baseline levels (mean 52.5, p-value < 0.05). Analysis of the EORTC PF sub-scale demonstrated a similar trend; however, the baseline and post-operative difference was not significant (p-value=0.15 for both FUP). Finding supports PROMIS PF ability to measure high functioning cancer patients.
Conclusions: Among a subset of pts who completed all surveys in the I-SPY 2 QOL substudy, PF did not return to baseline at 6-12 months post-operatively. Through transition to an electronic platform of data collection we hope to improve compliance with survey completion. We continue to analyze other QOL measures and plan to correlate QOL data with treatment arm, adverse events, comorbidities, and response to neoadjuvant treatment.

Abstract
The present study was designed to evaluate the effects of metformin on metabolic and endocrine parameters in patients with polycystic ovary syndrome (PCOS). The study included 40 patients with PCOS. Patients were divided into 2 groups based on whether they will receive metformin (500 mg 3 times a day, n=20) or placebo (n=20) for 3 consecutive months. Serum concentrations of fasting blood glucose, insulin, HOMA-IR, INSL-3, visfatin, FSH, and LH were measured at baseline and after 3 months of therapy. The key endocrine and metabolic parameters significantly changed after metformin treatment. The systolic and diastolic blood pressures were significantly reduced in the metformin group after treatment compared to placebo (p<0.001). A significant reduction in the size of the right ovary was observed after metformin treatment (p=0.05), while no change was found in the size of left ovary (p>0.12). Moreover, a significant reduction was observed in the serum levels of FSH (p>0.01), LH (p>0.001), and visfatin (p>0.001) after metformin treatment. However, HOMA-IR (which is used to assess insulin resistance) failed to reach the statistical significance (p=0.20). We conclude that metformin treatment in females with PCOS showed significant improvement in systolic and diastolic blood pressures. In addition, an improvement in the hormonal profile in the form of reduction in LH, FSH, and visfatin levels was observed. Thus, therapeutic intervention with metformin could be of clinical importance in high-risk group of young females with PCOS.
