Abstract
Doubly electrophilic pyrazabole derivatives (pyrazabole = [H2B(μ-C3N2H3)]2) combined with one equiv. of base effect the ortho-borylation of N-alkyl anilines. Initial studies found that the bis(trifluoromethane)sulfonimide ([NTf2]-) pyrazabole derivative, [H(NTf2)B(μ-C3N2H3)]2, is highly effective for ortho-borylation, with this process proceeding through N-H borylation and then ortho C-H borylation. The activation of pyrazabole by I2 was developed as a cheaper and simpler alternative to using HNTf2 as the activator. The addition of I2 forms mono or ditopic pyrazabole electrophiles dependent on stoichiometry. The ditopic electrophile [H(I)B(μ-C3N2H3)]2 was also effective for the ortho-borylation of N-alkyl-anilines, with the primary C-H borylation products readily transformed into pinacol boronate esters (BPin) derivatives. Comparison of borylation reactions using the di-NTf2-and the diiodo-pyrazabole congeners revealed that more forcing conditions are required with the latter. Furthermore, the presence of iodide leads to competitive formation of side products, including [HB(μ-C3N2H3)3BH]+, which are not active for C-H borylation. Using [H(I)B(μ-C3N2H3)]2 and 0.2 equiv. of [Et3NH][NTf2] combines the higher yields of the NTf2 system with the ease of handling and lower cost of the iodide system generating an attractive process applicable to a range of N-alkyl-anilines. This methodology represents a metal free and transiently directed C-H borylation approach to form N-alkyl-2-BPin-aniline derivatives.

Abstract
PURPOSE/OBJECTIVE(S) Published data supports the use of very high dose intensity modulated radiotherapy (IMRT) in achieving high efficacy and low toxicity for high-risk prostate cancer (HRPCa). This phase II multi-institutional non-randomized prospective dose escalation study using intensity modulated radiotherapy (IMRT) for high risk N0M0 prostate cancer was designed to investigate dose escalation using 1.8 Gy increments from baseline 75.6 Gy up to maximum 81 Gy, once dose volume constraints were adhered to. MATERIALS/METHODS Inclusion criteria were patients undergoing a radical course of RT for high and very high-risk disease, defined as one or more of the criteria ≥ T3*, ≥ Gleason 8, Prostate specific antigen (PSA) > 20ng/ml. All patients received Androgen Deprivation Therapy (ADT) and none had radiological evidence of distant metastatic disease. The primary objective was to determine if dose escalated IMRT for high risk localized prostate cancer could provide freedom from biochemical relapse (BR; PSA rising > nadir +2ng/mL or initiation of salvage hormone therapy) similar to that reported in the literature. The Kaplan-Meier method was used to estimate survival times. Secondary objectives included OS, Disease Free Survival (DFS), and the incidence and severity of Genito-urinary (GU), Gastro-intestinal (GI) and erectile dysfunction (ED) toxicities (CTCAE v.3). Toxicities and performance status were collected and graded weekly during RT, 2 months after completing RT, 8 months' post RT, and 6 monthly thereafter to year five and annually thereafter to year nine. RESULTS A total of 230 evaluable patients were enrolled between April 2009 and June 2016. The median follow-up was 7.3 years. The cumulative proportion of patients surviving without BR at 5 years was 91% (95% Confidence Interval (CI): 86% to 94%). Overall survival at 5 and 7 years was 92% (88% to 95%) and 89% (83% to 92%) respectively, while the cumulative proportion of patients free from disease was 89% (84% to 93%) at 5 years and 81% (75% to 86%) at 7 years. The incidence of acute G2 and G3 toxicities were; GU; 57.8% G2, 12.6% G3, GI; 15.2% G2, 0.4% G3, ED; 30.0% G2 and 61.7% G3. The incidence of late G2, G3 and G4 toxicities were; GU; 40.9% G2, 8.7% G3, GI; 36.5% G2, 2.2% G3, 0.4% G4, ED; 11.7% G2 and 86.1% G3. The percentage of patients receiving each dose level was; 3.5% received 75.6Gy in 42 fractions, 2.2% received 77.4Gy in 43 fractions, 93% received 81Gy in 45 fractions. CONCLUSION The findings indicate that high-dose IMRT is well tolerated and is associated with excellent long-term tumor-control outcomes in patients with localized high and very high-risk prostate cancer, with 91% of patients surviving at 5 years without biochemical relapse. The rates of long term G3 GU and GI toxicity were low at 8.7% and 0.4% respectively.

Abstract
PURPOSE Cyberattacks are increasing in health care and cause immediate disruption to patient care, have a lasting impact, and compromise scientific integrity of affected clinical trials. On the May 14, 2021, the Irish health service was the victim of a nationwide ransomware attack. Patient care was disrupted across 4,000 locations, including 18 cancer clinical trials units associated with Cancer Trials Ireland (CTI). This report analyses the impact of the cyberattack on the organization and proposes steps to mitigate the impact of future cyberattacks. METHODS A questionnaire was distributed to the units within the CTI group; this examined key performance indicators for a period of 4 weeks before, during, and after the attack, and was supplemented by minutes of weekly conference call with CTI units to facilitate information sharing, accelerate mitigation, and support affected units. A total of 10 responses were returned, from three private and seven public hospitals. RESULTS The effect of the attack on referrals and enrollment to trials was marked, resulting in a drop of 85% in referrals and 55% in recruitment before recovery. Radiology, radiotherapy, and laboratory systems are heavily reliant on information technology systems. Access to all was affected. Lack of preparedness was highlighted as a significant issue. Of the sites surveyed, two had a preparedness plan in place before the attack, both of these being private institutions. Of the eight institutions where no plan was in place, three now have or are putting a plan in place, whereas no plan is in place at the five remaining sites. CONCLUSION The cyberattack had a dramatic and sustained impact on trial conduct and accrual. Increased cybermaturity needs to be embedded in clinical trial logistics and the units conducting them.

Abstract
e13614 Background: Cancer trials in Ireland are conducted in both public Health Service Executive (HSE) and private hospitals and are overseen by Cancer Trials Ireland (CTI). On the 14th of May 2021 the Irish National HSE was the victim of a “Conti” ransomware attack. The attack triggered a “Critical Incident Process,” and the shutting down of all HSE IT systems at a national level. Disruption to patient care across the HSE’s 4000 locations, 54 acute hospitals, and 70,000 connected devices was drastic, immediate and without warning. Methods: The purpose of this study is to quantify the impact of the attack on the clinical trials network. A questionnaire was distributed by CTI to the 16 trials units within the group, this examined patient referrals and key performance indexes for a period of 4 weeks; prior, during, and after the attack. A total of 10 responses were returned, with a split of 3 private and 7 HSE hospitals. Results: The effect of the attack on referrals and enrollment to clinical trials was marked. In the 4 weeks prior to the attack 273 patients in total were referred to the trials units for screening, this fell to 41 patients in the 4 weeks during and recovering to 323, 4 weeks after. 49 patients were enrolled in trials prior the attack, 22 during and 38 after, a drop of 85% in referrals and 55% in recruitment to trials before recovery. Radiotherapy delivery was interrupted for patients on treatment or delayed for those initiating it. Radiology, lab systems and radiotherapy are heavily reliant on IT systems. Access to all was impacted, with only urgent diagnostic tests being carried out. Requesting tests and reports pivoted to a paper based systems. With staff having to present in person to request and collect reports. Patient safety was prioritized, with accurate paper records and logs in lieu of electronic records. Scientific integrity of trials involving combined modality or radiotherapy was compromised in HSE hospitals. No change in adverse outcomes was reported across all units surveyed before, during and after the attack. Normal access to emails in sites that were impacted ranged from days at a minimum to 6 weeks in the worst affected centers. Normal access to radiology and lab tests took on average 26 and 32 days respectively. Conclusions: A significant issue highlighted by the cyber-attack was the lack of redundancy in the IT systems used throughout Irish hospitals on a daily basis and a lack of a plan when these systems fail. Of the 10 sites surveyed, 2 had a preparedness plan in place prior to the attack, both of these private institutions. Of the 8 institutions where no plan was in place only 3 now have or are putting a plan in place, no plan is in place in the 5 remaining sites. At this time one HSE hospital has been subject to a repeat ransomware attack and patient data from another has been released on the dark web. Reviewing the impact of the cyber attack on CTI highlights the usefulness of preparedness, with units that had a plan in place prior to the attack least affected overall.

Abstract
Background: Screening for prostate cancer with prostate specific antigen and digital rectal examination allows early diagnosis of prostate malignancy but has been associated with poor sensitivity and specificity. There is also a considerable risk of over-diagnosis and over-treatment, which highlights the need for better tools for diagnosis of prostate cancer. This study investigates the potential of high throughput Raman and Fourier Transform Infrared (FTIR) spectroscopy of liquid biopsies for rapid and accurate diagnosis of prostate cancer. Methods: Blood samples (plasma and lymphocytes) were obtained from healthy control subjects and prostate cancer patients. FTIR and Raman spectra were recorded from plasma samples, while Raman spectra were recorded from the lymphocytes. The acquired spectral data was analysed with various multivariate statistical methods, principal component analysis (PCA), partial least squares discriminant analysis (PLS-DA) and classical least squares (CLS) fitting analysis. Results: Discrimination was observed between the infrared and Raman spectra of plasma and lymphocytes from healthy donors and prostate cancer patients using PCA. In addition, plasma and lymphocytes displayed differentiating signatures in patients exhibiting different Gleason scores. A PLS-DA model was able to discriminate these groups with sensitivity and specificity rates ranging from 90% to 99%. CLS fitting analysis identified key analytes that are involved in the development and progression of prostate cancer. Conclusions: This technology may have potential as an alternative first stage diagnostic triage for prostate cancer. This technology can be easily adaptable to many other bodily fluids and could be useful for translation of liquid biopsy-based diagnostics into the clinic.

Abstract
Hemolysis is a very common phenomenon and is referred as the release of intracellular components from red blood cells to the extracellular fluid. Hemolyzed samples are often rejected in clinics due to the interference of hemoglobin and intracellular components in laboratory measurements. Plasma and serum based vibrational spectroscopy studies are extensively applied to generate spectral biomarkers for various diseases. However, no studies have reported the effect of hemolysis in blood based vibrational spectroscopy studies. This study was undertaken to evaluate the effect of hemolysis on infrared and Raman spectra of blood plasma. In this study, prostate cancer plasma samples (n = 30) were divided into three groups (nonhemolyzed, mildly hemolyzed, and moderately hemolyzed) based on the degree of hemolysis and FTIR and Raman spectra were recorded using high throughput (HT)-FTIR and HT-Raman spectroscopy. Discrimination was observed between the infrared and Raman spectra of nonhemolyzed and hemolyzed plasma samples using principal component analysis. A classical least square fitting analysis showed differences in the weighting of pure components in nonhemolyzed and hemolyzed plasma samples. Therefore, it is worth to consider the changes in spectral features due to hemolysis when comparing the results within and between experiments.

Abstract
Radiation therapy (RT) is used to treat approximately 50% of all cancer patients. However, RT causes a wide range of adverse late effects that can affect a patient's quality of life. There are currently no predictive assays in clinical use to identify patients at risk of normal tissue radiation toxicity. This study aimed to investigate the potential of Fourier transform infrared (FTIR) spectroscopy for monitoring radiotherapeutic response. Blood plasma was acquired from 53 prostate cancer patients at five different time points: prior to treatment, after hormone treatment, at the end of radiotherapy, two months post radiotherapy and eight months post radiotherapy. FTIR spectra were recorded from plasma samples at all time points and the data was analysed using MATLAB software. Discrimination was observed between spectra recorded at baseline versus follow up time points, as well as between spectra from patients showing minimal and severe acute and late toxicity using principal component analysis. A partial least squares discriminant analysis model achieved sensitivity and specificity rates ranging from 80% to 99%. This technology may have potential to monitor radiotherapeutic response in prostate cancer patients using non-invasive blood plasma samples and could lead to individualised patient radiotherapy.

Abstract
Background Our aim was to assess the heterogeneity of high-risk (HR) prostate cancer managed with high-dose external beam radiotherapy (EBRT) with androgen deprivation therapy (ADT). Methods We identified 547 patients who were treated with modern EBRT from 1997 to 2013, of whom 98% received ADT. We analyzed biochemical relapse-free survival (bRFS) and distant metastases-free survival (DMFS). Results Median EBRT dose was 74 Gy, and median ADT duration was 8 months. At 5 years, the DMFS was 85%. On multivariate analysis, significant predictors of shorter bRFS were biopsy Gleason score (bGS) of 8 to 10, higher prostate-specific antigen (PSA) level, shorter duration of ADT and lower radiation dose while predictors of shorter DMFS were bGS of 8 to 10, higher PSA level, and lower radiation dose. We identified an unfavorable high-risk (UHR) group of with 2–3 HR factors based on 2015 National Comprehensive Cancer Network (NCCN) criteria and a favorable high-risk (FHR) group, with 1 HR feature. Comparing very-HR prostate cancer, UHR & FHR, 5 year bRFS rates were 58.2%, 66.2%, and 69.2%, and 5 year DMFS rates were 78.4%, 81.2%, and 88.0%. Conclusion Patients with multiple HR factors have worse outcome than patients with 1 HR factor. Future studies should account for this heterogeneity in HR prostate cancer.

Abstract
Conjugated linoleic acid (CLA) refers to a group of fatty acid isomers of linoleic acid. Recent research shows that CLA affects body composition, lipoprotein metabolism, inflammationand carcinogenesis. Therefore, CLA may have potential as a therapeutic nutrient with respect to many common diseases, including obesity, atherosclerosis, chronic inflammatory diseases and cancer. Animal studies show that CLA is a potent anti-adipogenic nutrient, reducing adipose tissue mass and increasing lean mass. However, the effect of CLA on body composition in human subjects has been less spectacular. Several studies have demonstrated that CLA significantly improves plasma cholesterol and triacylglycerol metabolism in a number of animal models. These studies also showed that CLA inhibits the progression and pathogenesis of atherosclerosis. Whilst CLA has also been shown to improve triacylglycerol metabolism in human subjects, it has not been determined whether CLA affects atherogenesis. Animal models show that CLA-rich diets modulate the inflammatory response and preliminary trials with human subjects show that CLA affects the cell-mediated immune response. The molecular basis of the health effects of CLA has not been elucidated, but it is probable that CLA mediates its effect in a number of ways including altered eicosanoid or cytokine metabolism and/orby a direct effect of dietary fats on gene transcription. Most of our knowledge is based on in vitro and animal studies; the challenge is to define the nature and molecular basis of any health effects of CLA in human subjects.

Abstract
A large number of studies in recent years have investigated the effects of hyperlipidaemias and diabetes on cholesteryl ester transfer protein (CETP) on neutral lipid transfer activity and plasma lipids. There has been an ongoing debate as to whether CETP is pro- or anti-atherogenic as it provides a mechanism for the transfer of cholesterol from the cardioprotective HDL subfraction to the potentially atherogenic LDL subfraction. This study was designed to investigate whether there was significant variability of CETP mass and activity in a large normolipidaemic population and whether there is an association between CETP and plasma lipoprotein composition. The presence of a known polymorphism of CETP gene (Taq 1B) was investigated to see if there was any association between this polymorphism and CETP mass and activity, and plasma lipids. There was significant (P < 0.0001) increase in CETP mass and activity in plasma postprandially at 6 h. Using multiple stepwise regression analysis there was significant association with fasting CETP mass and activity (beta = 0.055; P = 0.002) and triacylglycerol-rich lipoprotein (beta = 0.013; P = 0.005) and postprandial CETP mass (beta = 0.254; P = 0.007). Repeated-measures analysis showed a strong association between the absence of Taq 1B polymorphism and low CETP mass and elevated HDL- and HDL2-cholesterol and HDL-phospholipid concentrations than did those who were homozygous or heterozygous for the presence of the restriction site.

Abstract
Elevated levels of coagulation factor VII activity (FVIIc) are associated with increased risk of CHD. FVIIc is strongly determined by two polymorphisms (R353Q and 0/10 base pairs (bp)) and plasma triacylglycerol (TAG) concentrations. The Q and 10 bp polymorphisms show strong linkage disequilibrium and have been associated with lower levels of fasting FVII, but there has been little investigation of the effect of these genotypes on the postprandial FVII metabolism. The present study demonstrated that fasting activated factor VII (FVIIa) and factor VII antigen (FVIIag) levels were significantly lower in the heterozygotes carrying the Q and 10 bp alleles (n 12), than in the R/0 bp homozygotes (n 12) (43.0 (SE 4.8) v. 23.9 (SE 6.5) mU/ml and 85.7 (SE 5.4) v. 71.6 (SE 7.5)% respectively). During postprandial lipaemia there was a significant increase in FVIIa in R/0 bp homozygotes but not in the heterozygotes carrying the Q and 10 bp alleles. The proportion of FVIIa (FVIIa:FVIIag) increased in the homozygotes but not in the heterozygotes (2.04 (SE 0.35) v. 1.20 (SE 0.26) respectively). Therefore possession of the relatively common Q and 10 bp alleles is not associated with postprandial activation of FVII, which may in turn have a protective effect against CHD.
