Abstract
Double differential neutron fluence distributions were measured in the 7Li(p,n)7Be reaction for proton beam energies 7, 9 and 12 MeV. Seven liquid scintillator based detectors were employed to measure neutron fluence distributions using the Time of Flight technique. Neutron ambient dose equivalents were determined from the measured fluence distribution using ICRP (International Commission on Radiological Protection) recommended fluence to dose equivalent conversion coefficients. Neutron dose equivalents were also measured using a conventional BF3 detector based REM counter. Ambient dose equivalent measured by the REM counter is found to be in agreement with that determined from the neutron fluence spectra within their uncertainties. Angular distributions of the ambient dose equivalents were also determined from the measured fluence distributions at different angles.

Abstract
BACKGROUND Cheminformatics is a fascinating emerging subfield of chemical graph theory that studies quantitative structure-activity and property relationships of molecules and, in turn, uses these to predict the physical and chemical properties, which are extremely useful in drug discovery and optimization. Knowledge discovery can be put to use in pharmaceutical data matching to help in finding promising lead compounds. METHOD Topological descriptors are numerical quantities corresponding to the chemical structures that are used in the study of these phenomena. RESULT This paper is concerned with developing the generalized analytical expression of topological descriptors for zeolite ACO structures with underlying degree and degree-sum parameters. CONCLUSION To demonstrate improved discrimination power between the topological descriptors, we have further modified Shannon's entropy approach and used it to calculate the entropy measures of zeolite ACO structures.

Abstract
Entropy of a connected network is a quantitative measure from information theory that has triggered a plethora of research domains in molecular chemistry, biological sciences and computer programming due to its inherent capacity to explore the structural characteristics of complex molecular frameworks that have low structural symmetry as well as high diversity. The analysis of the structural order is greatly simplified through the topological indices based graph entropy metrics, which are then utilized to predict the structural features of molecular frameworks. This predictability has not only revolutionized the study of zeolitic frameworks but has also given rise to new generations of frameworks. We make a comparative study of two versatile framework topologies namely zeolites BCT and DFT, which have been widely utilized to create a new generation of frameworks known as metal organic frameworks. We discuss bond-additive topological indices and compute entropy measure descriptors for zeolites BCT and DFT using degree and degree-sum parameters. In addition, we perform bond-wise scaled comparative analysis between BCT and DFT which shows that zeolite BCT has greater entropy values compared to zeolite DFT.

Abstract
The physicochemical characteristics of polycyclic aromatic compounds critical to environmental modelling such as octanol partition coefficients, solubility, lipophilicity, polarity and several equilibrium constants are functions of their underlying molecular structures, prompting the development of mathematical models to predict such characteristics for which experimental results are difficult to obtain. We propose twelve novel descriptors derived from geometric, harmonic and Zagreb degree-based descriptors and then test the effectiveness of these descriptors on a data set consisting of 55 benzenoid hydrocarbons of environmental importance. Our computations show that the proposed descriptors have a good linear correlation and predictive power when compared to the degree and distance type descriptors. We have also derived the QSPR expressions for four properties of a large series of polycyclic aromatics arising from circumscribing coronenes and show that a scaling factor can be deduced to derive physicochemical properties of such series up to 2D graphene sheets.

Abstract
BACKGROUND Current management practices and outcomes in weaning from invasive mechanical ventilation are poorly understood. We aimed to describe the epidemiology, management, timings, risk for failure, and outcomes of weaning in patients requiring at least 2 days of invasive mechanical ventilation. METHODS WEAN SAFE was an international, multicentre, prospective, observational cohort study done in 481 intensive care units in 50 countries. Eligible participants were older than 16 years, admitted to a participating intensive care unit, and receiving mechanical ventilation for 2 calendar days or longer. We defined weaning initiation as the first attempt to separate a patient from the ventilator, successful weaning as no reintubation or death within 7 days of extubation, and weaning eligibility criteria based on positive end-expiratory pressure, fractional concentration of oxygen in inspired air, and vasopressors. The primary outcome was the proportion of patients successfully weaned at 90 days. Key secondary outcomes included weaning duration, timing of weaning events, factors associated with weaning delay and weaning failure, and hospital outcomes. This study is registered with ClinicalTrials.gov, NCT03255109. FINDINGS Between Oct 4, 2017, and June 25, 2018, 10 232 patients were screened for eligibility, of whom 5869 were enrolled. 4523 (77·1%) patients underwent at least one separation attempt and 3817 (65·0%) patients were successfully weaned from ventilation at day 90. 237 (4·0%) patients were transferred before any separation attempt, 153 (2·6%) were transferred after at least one separation attempt and not successfully weaned, and 1662 (28·3%) died while invasively ventilated. The median time from fulfilling weaning eligibility criteria to first separation attempt was 1 day (IQR 0-4), and 1013 (22·4%) patients had a delay in initiating first separation of 5 or more days. Of the 4523 (77·1%) patients with separation attempts, 2927 (64·7%) had a short wean (≤1 day), 457 (10·1%) had intermediate weaning (2-6 days), 433 (9·6%) required prolonged weaning (≥7 days), and 706 (15·6%) had weaning failure. Higher sedation scores were independently associated with delayed initiation of weaning. Delayed initiation of weaning and higher sedation scores were independently associated with weaning failure. 1742 (31·8%) of 5479 patients died in the intensive care unit and 2095 (38·3%) of 5465 patients died in hospital. INTERPRETATION In critically ill patients receiving at least 2 days of invasive mechanical ventilation, only 65% were weaned at 90 days. A better understanding of factors that delay the weaning process, such as delays in weaning initiation or excessive sedation levels, might improve weaning success rates.

Abstract
While the dissociative recombination (DR) of ground-state molecular ions with low-energy free electrons is generally known to be exothermic, it has been predicted to be endothermic for a class of transition-metal oxide ions. To understand this unusual case, the electron recombination of titanium oxide ions (TiO+) with electrons has been experimentally investigated using the Cryogenic Storage Ring. In its low radiation field, the TiO+ ions relax internally to low rotational excitation (≲100 K). Under controlled collision energies down to ∼2 meV within the merged electron and ion beam configuration, fragment imaging has been applied to determine the kinetic energy released to Ti and O neutral reaction products. Detailed analysis of the fragment imaging data considering the reactant and product excitation channels reveals an endothermicity for the TiO+ dissociative electron recombination of (+4 ± 10) meV. This result improves the accuracy of the energy balance by a factor of 7 compared to that found indirectly from hitherto known molecular properties. Conversely, the present endothermicity yields improved dissociation energy values for D0(TiO) = (6.824 ± 0.010) eV and D0(TiO+) = (6.832 ± 0.010) eV. All thermochemistry values were compared to new coupled-cluster calculations and found to be in good agreement. Moreover, absolute rate coefficients for the electron recombination of rotationally relaxed ions have been measured, yielding an upper limit of 1 × 10-7 cm3 s-1 for typical conditions of cold astrophysical media. Strong variation of the DR rate with the TiO+ internal excitation is predicted. Furthermore, potential energy curves for TiO+ and TiO have been calculated using a multi-reference configuration interaction method to constrain quantum-dynamical paths driving the observed TiO+ electron recombination.

Abstract
Reliable provision of emergency equipment in Critical Care is key to ensure patient safety during medical emergencies and transfers. A problem was identified in incident reports and external inspections of processes that ensured the provision of such equipment for use by critical care teams in non-critical care areas in the form of grab bags. A comprehensive project was undertaken to tackle this including the provision of a bespoke digital system. Existing systems were reliant on staff remembering to check equipment and document checks on paper and there was no formal ability to hand over ongoing problems. A local project management approach, ‘7 Steps to Quality Improvement’, which integrated many of the philosophies and tools from Healthcare Improvement was used. A bespoke digital system was designed and implemented with integrated improvements in equipment stocking ergonomics. The reliability of documented equipment checks improved significantly, there was a significant reduction in the number of incident reports regarding emergency equipment and the time spent by staff doing equipment checks was reduced substantially with significant cost and resource improvements. This was so successful the format has been rapidly translated and spread to other areas such as operating theatres’ difficult airway trolleys. Undertaking a structured quality improvement approach, using appropriate stakeholder engagement, digitalisation of systems and improvements in basic system ergonomics can have a substantial impact on the reliability and safety of emergency equipment provided for use by members of the critical care team.

Abstract
Corona Virus Disease 2019 (COVID-19) was declared a pandemic in March 2020. This global health crisis caused thousands of pneumonia related death all over the world since December 2019. RT-PCR is the primary test for diagnosis of COVID-19, though its sensitivity and specificity is variable. Several studies revealed that chest HRCT complements RT-PCR in highly suspected cases or in false negative RT-PCR and helps to gauge disease severity. This study was carried out with an aim to find out the severity scores of chest HRCT in hospitalized patients with COVID-19. This cross sectional descriptive type of observational study was carried out at COVID-19 unit of Sylhet Women's Medical College Hospital, Bangladesh from April 2021 to September 2021. Data were collected from purposively selected 204 patients with COVID-19 by face to face interview, chest HRCT and necessary laboratory investigations. Informed written consent was taken from the participants of the study at the beginning of the interview. Data were analyzed by using SPSS version 21.0. The results of the study showed that mean age of the patients with COVID-19 was 57.9 years with a standard deviation of ±15.8 years. Majority of them (121, 59.3%) were female and the remaining (83, 40.7%) were male. Regarding co-morbidities it was found that each 115 (56.4%) patients were hypertensive and diabetic. Thirty five (16.2%) had ischemic heart disease; 3(1.5%) had congestive cardiac failure and 2(1.0%) had asthma. One (0.5%) patient has atrial fibrillation. In case of 160(78.4%) RT-PCR confirmed patients with COVID-19, chest HRCT was found positive and in 44(21.6%) it was found negative. Among the positive cases mild (7 or less) chest HRCT score was found in 26(12.7%) patients; moderate (8-17) score was found in highest number of patients (128, 62.7%) and severe (18 or more) chest HRCT score was found in 6(2.9%) patients with COVID-19. Chi-square test was carried out to assess the relation of chest HRCT scores with age group, sex, troponin-I, D-Dimer and clinical outcomes within CCU but statistically significant relation was not found (p>0.05). The negative scans were highest (20, 9.8%) in the age group of 41-60 years. Mild, moderate and severe chest HRCT scores was found highest in the age group of 61-80 years (13, 6.4%; 51, 25.0% and 5, 2.5% respectively) (p=0.508). Chest HRCT scans were negative in 18(8.8%) male and 26(12.7%) female. Mild scores were equally distributed between each sex i.e. male 13(6.4%) and female 13(6.4%). Both moderate and severe scores were found more in female (77, 37.7% and 5, 2.5% respectively) than male (51, 25.0% and 1, 0.5% respectively) (p=0.492). Negative chest HRCT scans, mild, moderate and severe scores-all were found more in patients with elevated D-Dimer (p=0.194). Among 204 patients one (0.5%) died in the CCU who had mild score of chest HRCT (p=0.076) but highly elevated Troponin-I (21.70ng/mL). Chest HRCT was found positive among 78.4% of patients with COVID-19 confirmed by RT-PCR. Chest HRCT can help physicians to detect suspected cases and to assess the severity and outcome of the disease. However, further research is recommended to clarify the role of chest HRCT in assessing severity of COVID-19 and prediction of prognosis.

Abstract
BackgroundActivated fibroblasts are the main drivers of skin fibrosis in SSc. We have recently identified dimethyl alpha-ketoglutarate (dm-aKG) as a potential repressor of myofibroblast differentiation and profibrotic activity in cultured skin fibroblasts.ObjectivesTo further analyse the clinical translation of our findings by investigating the antifibrotic capacity of dm-aKG on explanted skin biopsies from SSc patients.MethodsWe cultured forearm punch skin biopsies from SSc patients (n=10) for 24h ex vivo in the presence/absence of 6 mM dm-aKG. Thereafter, skin biopsies (n=4) were dissociated into single cells using a combined mechanical-enzymatic dissociation protocol, followed by single cell (sc)RNA-seq library preparation (10x Genomics) and sequencing (Illumina, NovaSeq6000, 50,000 reads/cell). We mapped the scRNA-seq reads to the reference genome GRCh38.p13 and analysed the data with R/Bioconductor tools. We deconvoluted cell types in bulk skin transcriptomes from SSc cohorts (GSE: 45485, 59785, 9285, 32413) using human skin scRNA-seq data1. The secretion of IL-6, procollagen-1, PRO-C1 (N-terminal type I collagen pro-peptide), C1M (MMP-degradation fragment of type I collagen), and fibronectin (FBN-C) from cultured skin (n=10) was measured in supernatants by ELISA. We analysed gene and protein expression in TGFβ-activated healthy and SSc dermal fibroblasts (DF, n=10) treated or not with dm-aKG using qPCR, Western blot and ELISA. Contractile properties of DF were assessed by gel contraction assay. Traction forces generated by DF were determined by reference-free traction force microscopy.ResultsDissociated cultured SSc skin exhibited comparable cell yield and viability in the presence (20,203; 89%) and absence (25,280; 93%) of dm-aKG, respectively. scRNA-seq skin analysis included 20,869 high quality single cell profiles segregating into 10 distinct skin cell populations (Figure 1A). This analysis demonstrated decreased proportion of fibroblasts and increased proportion of keratinocytes in dm-aKG treated skin (p<0.05; Figure 1B). Among skin cell types, skin fibroblasts exhibited the largest amount of differentially expressed genes upon dm-aKG treatment (44%, n=779, x-fold>0.5, FDR<0.05), suggesting that these cells are key targets of dm-aKG therapy in SSc skin. We identified inflammatory/cytokine signalling (hub genes IL6, STAT1) and extracellular matrix (ECM) organization (hub genes MMP1, ITGB3) as top downregulated biological processes in fibroblasts in dm-aKG treated SSc skin (Figure 1C), coinciding with a decreased abundance of proinflammatory skin fibroblast subpopulation. Specifically, these cells were identified as the main source of IL6 (Figure 1D) and were enriched in SSc skin as revealed by deconvolution analysis of skin transcriptomes. Furthermore, dm-aKG reduced the secretion of IL-6, procollagen-1 and C1M, but not pro-C1 and FBN-C, from cultured skin explants. In cultured DF, dm-aKG blocked the inflammatory (IL-6, pSTAT3), profibrotic (aSMA, Fibronectin, Procollagen-1, Pro-C1) and contractile activities, and significantly diminished traction forces exerted by DF on the matrix substrate.Figure 1.scRNA-seq – comparison of untreated and dm-aKG treated paired skin biopsies.

These results confirm that dm-aKG might represent a potential new therapeutic approach for efficient targeting of skin inflammation and fibrosis in SSc.References[1]He H et al.

Abstract
We present state-selected measurements of rotational cooling and excitation rates of CH^{+} molecular ions by inelastic electron collisions. The experiments are carried out at a cryogenic storage ring, making use of a monoenergetic electron beam at matched velocity in combination with state-sensitive laser dissociation of the CH^{+} ions for simultaneous monitoring of the rotational level populations. Employing storage times of up to 600 s, we create conditions where electron-induced cooling to the J=0 ground state dominates over radiative relaxation, allowing for the experimental determination of inelastic electron collision rates to benchmark state-of-the-art theoretical calculations. On a broader scale, our experiments pave the way to probe inelastic electron collisions for a variety of molecular ions relevant in various plasma environments.

Abstract
Conventionally, the general understanding of Municipal Solid Waste (MSW) management is collecting solid waste and its disposal through its developed channels or outside contracts. However, depending upon the situation and context, the definition of MSW varies between countries across the globe. For instance, in countries like Singapore and Japan, Municipal Solid Waste is defined as general waste. However, while categorizing the general waste, the industrial waste component is considered for Singapore and not for Japan. Similarly, different countries associate different definitions for MSW and it becomes a difficult challenge to suggest a single unified definition applicable for all countries. This paper aims to do a comparative analysis of Waste management in Tier-II cities of India, Kochi and Indore. Kochi is ranked 372nd and the latter 1st according to the latest Swachh Survekshan undertaken as part of the Swachh Bharat Abhiyan (Urban) by the Ministry of Housing and Urban Affairs. This paper highlights what the key elements missing out in the management of waste in Kochi from the reference perspective of Indore and identifying the measures Kochi needs to undertake to improve its ranking among the cleanest city in India are.

Abstract
We report a method for the enantioselective hydrogenation of annulated arenes using 4H-pyrido[1,2-a]pyrimidinones as substrates. The method selectively generates multiple stereocenters in adjacent rings leading to architecturally complex motifs, which resemble bioactive molecules. The mechanistic study of the stereochemical outcome revealed that the catalyst is able to overcome substrate stereocontrol providing all-cis-substituted products predominantly. In a sequential protocol, a matching interaction between catalyst and substrate stereocontrol is achieved that facilitates diastereo- and enantioselective access to trans-products.

Abstract
INTRODUCTION Maternal obesity increases neonatal risk for obesity and metabolic syndrome later in life. Prior attempts to break this intergenerational obesity cycle by limiting excessive gestational weight gain have failed to reduce neonatal adiposity. Alternatively, pre-conception lifestyle interventions may improve the in utero metabolic milieu during early pregnancy leading to improved fetal outcomes. This randomized controlled trial (RCT) is evaluating whether a lifestyle intervention to reduce weight and improve maternal metabolism in preparation for pregnancy (LIPP) attenuates neonatal adiposity, compared to standard medical advice. MATERIAL AND METHODS Overweight/class 1 obese women after a previous pregnancy, ~12 weeks postpartum, preparing for a subsequent pregnancy, will be block randomized (1:1) to either LIPP or standard of care in a parallel design. Randomization is stratified by lactation status and overweight vs. class 1 obesity. The LIPP program consists of intensive short-term weight loss followed by weight maintenance until conception using supervised exercise and a low glycemic Mediterranean diet. PRIMARY OUTCOMES Group differences in neonatal adiposity at birth assessed by PEA POD and placental mitochondrial lipid metabolism. SECONDARY OUTCOMES Group differences in maternal pregravid and gestational body composition, insulin sensitivity, β-cell function, fasting metabolic and inflammatory biomarkers, and overall quality of life. Exploratory outcomes include umbilical cord blood insulin resistance, lipid profile and inflammation. DISCUSSION This RCT will determine the efficacy of maternal weight loss prior to pregnancy on reducing neonatal adiposity. Findings may change standard obstetrical care by providing Level 1 evidence on lifestyle interventions improving neonatal outcomes for women planning for pregnancy. CLINICAL TRIAL REGISTRATION NCT03146156.

Abstract
Anaplastic thyroid cancer (ATC) is a highly uncommon (less than 2% of thyroid malignancies) and aggressive type of cancer, with aggressive behavior and, therefore, exhibiting poor prognosis. ATC tumors are automatically labeled as stage IV disease regardless of standard criteria such as tumor burden or metastasis. ATC tumors require a diversified treatment approach that includes surgical resection, followed by a complete an aggressive combination of radiation and chemotherapy and/or palliative care. Despite best efforts, 1-year overall survival of patients is 20% to 40% with nearly universal mortality rate. Consequently, novel approaches (targeted therapy, immunotherapy) have been studied, alone or in combination, to improve the dire prognosis of these patients. BRAF V600E mutation is the most common genetic mutation found in ATC. We report the case of a 57-year-old man diagnosed with stage IVc (undifferentiated) ATC with hepatic and osseous metastases. The molecular analysis of the tumor revealed a V600E BRAF-mutation. The patient was treated with Dabrafenib and Trametinib, and achieved remission 5 weeks after starting the treatment. Subsequently, he had a thyroidectomy, and pembrolizumab was added to the two tyrosine kinase inhibitors. 9 months later he is still in remission. This case illustrates the importance of obtaining molecular information in anaplastic thyroid cancer and the urgent need of studies investigating the combination of tyrosine kinase inhibitors and check-point inhibitors in patients with V600E BRAF- mutations.

Abstract
The following report details the multidisciplinary treatment of a patient with motor neurone disease. The patient, who requested publication of this case, is a highly intelligent and distinguished robotic scientist. He was diagnosed with amyotrophic lateral sclerosis in 2017 and his personal approach to his condition has been to use modern technology and all treatment options to maximise his quality and duration of life. After his research, the patient decided that his life would be significantly improved by formation of an elective 'triple-ostomy', this being an end colostomy and suprapubic catheter (for continence), and a percutaneous gastrostomy (for nutrition). We report the peri-operative multidisciplinary approach taken with this case, the surgical procedures, the potential risks and the outcome. The patient is delighted with the result and aims to raise awareness that this may be a treatment option in highly selected patients.

Abstract
The epoch of first star formation in the early Universe was dominated by simple atomic and molecular species consisting mainly of two elements: hydrogen and helium. Gaining insight into this constitutive era requires a thorough understanding of molecular reactivity under primordial conditions. We used a cryogenic ion storage ring combined with a merged electron beam to measure state-specific rate coefficients of dissociative recombination, a process by which electrons destroy molecular ions. We found a pronounced decrease of the electron recombination rates for the lowest rotational states of the helium hydride ion (HeH+), compared with previous measurements at room temperature. The reduced destruction of cold HeH+ translates into an enhanced abundance of this primordial molecule at redshifts of first star and galaxy formation.

Abstract
AIM This symposium covers the gamut of Type 2 diabetes prevention, reversing established Type 2 diabetes, population-level delivery of weight loss programmes and personal insights into achieving and retaining substantial weight loss. RESULTS The NHS Diabetes Prevention Programme was launched in 2016 and rates of referral and attendance have both exceeded expectations. By March 2018, mean weight loss for completers (those attending more than 60% of sessions) was 3.2 kg reflecting considerable health benefits. Established Type 2 diabetes is now known to be a reversible condition in the early years, and the underlying mechanism is the removal of the excess fat from within liver and pancreas in these susceptible individuals. The Diabetes Remission Clinical Trial has shown that around half of a primary care population of people with Type 2 diabetes of less than 6 years' duration can be returned to non-diabetic blood glucose control which lasts at least 12 months. This raises the question of population-level intervention to achieve weight loss. The success of some mass weight loss programmes requires to be recognized. Reframing mass provision of weight loss support should be a vital part of our clinical strategy to prevent and treat Type 2 diabetes. However, the current obesogenic environment is a reality in which individuals must live. A personal account of achieving substantial and maintaining substantial weight loss provides an invaluable insight into practical problems encountered. All health professionals dealing with weight control should assimilate and reflect upon this understanding. CONCLUSIONS Effective prevention and long term reversal of Type 2 diabetes is feasible. The impact upon the individual must be considered during delivery of advice and support.

Abstract
Background. India is the “World’s Diabetes capital”, with half the diabetic population being women. Early detection of glucose intolerance during pregnancy offers a timely opportunity for screening, management and prevention of gestational diabetes mellitus (GDM) and prevents fetal complications.
Objective. The study assessed the prevalence of GDM in an Indian cohort using the Diabetes in Pregnancy Study group of India (DIPSI) criteria.
Methods. 200 pregnant women underwent two-phase testing with non-fasting 75-gram glucose challenge under Diabetes in Pregnancy Study group of India (DIPSI) criteria at <20 weeks and between 24-28 weeks period of gestation. A 3-hour 100-gm oral glucose tolerance test (OGTT) was used for confirmation. Repeat testing was done for women negative during the first-phase.
Results. Mean age was 24.26±3.75 years with 52.5% multigravidas. Mean Body Mass Index (BMI) was 20.7±3.07 kg/m2. The prevalence of GDM in study cohort was found to be 15.5% using the DIPSI criteria while the prevalence of GDM after 100 g OGTT was 13.0%. GDM was mostly seen to occur in women of 26-30-year age group. Statistically significant associations for age and GDM, and BMI and GDM were evidenced.
Conclusions. Maternal age of ≥25 years should be adopted as a risk factor for the development of GDM. The DIPSI criteria offer a cost-effective and an evidence-based protocol for a single-step definitive glucose test for both screening and diagnosis of pregnant patients belonging to any socio-economic strata; furthering its implementation for public health obstetrics.

Abstract
Abstract
Background: Oral stomatitis is a frequent adverse event (AE) associated with mTOR-inhibitor therapy, and can impact adherence. In BOLERO-2, patients (pts) with hormone receptor-positive (HR+) metastatic breast cancer (MBC) treated with exemestane plus everolimus (EVE), the incidence of all-grade (G) stomatitis or related AEs was 67%, with 24%/8% of pts developing G2/G3 stomatitis or related AEs, respectively (Perez et al ASCO 2013 Abs 7029). In BOLERO-2, 24% of pts required EVE dose reduction for stomatitis (Rugo et al Ann Oncol 2014;25:808). This study evaluated 2 steroid-based mouth rinses for the prevention or amelioration of oral stomatitis in pts with MBC treated with EVE. Methods: This prospective randomized phase II study enrolled postmenopausal pts (planned accrual=100) with HR+ MBC within the US Oncology Network who were initiating therapy with an aromatase inhibitor plus EVE (10 mg/day)(AIE). Pts were randomized 1:1 to prophylactic therapy with 1 of 2 oral rinses (ARM 1: MMW 480 ml recipe: 320 mL oral Benadryl, 2 g Tetracycline, 80 mg Hydrocortisone, 40 mL Nystatin suspension, water; or ARM 2: Prednisolone (P) 15mg/5mL oral solution, 1.8% alcohol). Pts were instructed to swish/expectorate 10 ml of the assigned rinse 4x daily starting with D1 of EVE treatment, for a total of 12 wks. The primary objective was to determine the incidence of G≥2 stomatitis or related oral AEs during the first 12 wks of treatment. Based on a historical estimate that ≥37% of pts receiving AIE develop G≥2 stomatitis, 50 pts for each arm were required to detect a reduction of the incidence of G≥2 stomatitis from 37% to <20%, with alpha = 0.05, 80% power, and a 1-sided test. Secondary objectives included assessment of AEs (all grades), determination of the percentage of pts requiring dose interruption/reduction of EVE or discontinuation of therapy due to toxicity, and evaluation of the impact of the oral rinses on the duration and severity of stomatitis. Results: As of 5/30/2016, a total of 104 pts have been randomized and 100 pts have received treatment (49 MMW; 51 P). Median age was 61 yrs (range 31-82 yrs). The incidence of stomatitis and related oral AEs (any grade) during the first 12 wks was 29% (n=14/49) and 27.5% (14/51) in the MMW and P arms respectively. The incidence of G2 oral AEs was 12% (6/49) and 8% (4/51) with MMW and P respectively. There was only 1 G3 oral AE (MMW arm), and no G4 events. There was 1 EVE dose reduction (MMW) and 4 EVE dose delays (3 MMW, 1 P) during the first 12 wks of treatment. No pts stopped the steroid mouth rinse therapy due to mouth rinse-related toxicity. Conclusion: These prospective data provide evidence of a reduced incidence of mTOR-associated oral AEs with prophylactic use of a steroid mouth rinse. The 29%/27.5% incidence of all-grade and 12%/8% incidence of G2 oral AEs, with only 1 G3 event, compare favorably with the 67% and 24%/8% incidence of all-grade and G2/3 stomatitis, respectively, in BOLERO-2. These data also show the safety and tolerability of these 2 steroid mouth rinses. Prophylactic use of steroid mouth rinses substantially decreases the incidence of G2/3 stomatitis and the need for EVE dose modifications.
