Abstract
PURPOSE/OBJECTIVE(S) Systemic immune, inflammatory, and nutritional indices have been shown to be prognostic for outcome across a range of tumor sites. However, a comprehensive analysis of these markers in patients with cervical cancer treated with definitive (chemo)radiotherapy [(C)RT] has not been performed. We hypothesized that systemic immune, inflammatory, and nutritional indices may be associated with progression free survival (PFS) and overall survival (OS) in patients undergoing definitive (C)RT for cervical cancer. MATERIALS/METHODS Patients with cervical cancer treated with definitive (C)RT from 1999 - 2015 were identified from a single cancer institution's retrospective clinicopathological database. Pre-treatment immune, inflammatory, and nutritional parameters were collected, and indices derived. Systemic immune-inflammation index (SII) = neutrophil count x platelet count / lymphocyte count(10^9/L); PLR = platelet count / lymphocyte count(10^9/L), NLR = neutrophil count / lymphocyte count (10^9/L); MLR = monocyte count / lymphocyte count (10^9/L); albumin to alkaline phosphatase ratio (AAPR) = serum albumin level (g/L)/alkaline phosphatase level (U/L) and prognostic nutritional index (PNI) = serum albumin (g/L) + 5 x lymphocyte count (10^9/L). Univariate analysis was first performed on each parameter as continuous variables for PFS and OS. For variables with statistically significant associations, ROC curves were analyzed to determine if an optimal cut point could be established for each outcome. Common cut points were then defined for each variable. PFS and OS were analyzed by the Kaplan-Meier method and the Log-Rank test. Multivariate analysis was performed using Cox regression with covariates of tumor stage, histology, and age. P-values of <0.05 were considered statistically significant. RESULTS A total of 196 patients were identified; median follow-up 7 years. 131 (67%) had stage I-II and 65 (33%) stage III-IV disease. 187 (95%) received CRT and 9 (5%) RT alone. Higher SII (≤700 vs >700; p = 0.01), higher PLR (≤ 250 vs >250; p<0.001) and higher NLR (≤ 5 vs >5; p = 0.003) were associated with worse PFS. Higher SII [≤700 vs >700: 5y OS 74.9 vs 55.8; p = 0.02], higher PLR [≤ 250 vs >250: 5y OS 69.9% vs 42.0%; p<0.001] and higher NLR [≤ 5 vs >5: 5y OS 65.3% vs 51.0%; p = 0.01] were associated with worse OS. MLR, AAPR and PNI were not associated with outcome on univariate analysis. On multivariate analysis, SII and PLR were independently associated with both PFS [SII: HR 1.647 (CI 1.029-2.639), p = 0.038; PLR: HR 2.301 (95% CI 1.507 - 3.512), p = <0.001], and OS [SII: HR 1.649 (95% CI 1.009-2.696), p = 0.046; PLR: HR 2.212 (95% CI 1.416-3.455), p<0.001]; NLR did not remain statistically significant. CONCLUSION SII and PLR, but not nutritional indices, were independently associated with PFS and OS in patients with cervical cancer treated with definitive (C)RT. Further evaluation of these systemic immune and inflammatory indices in a validation set will be required to better define their clinical utility.

Abstract
PURPOSE/OBJECTIVE(S) Hypomagnesemia is a common side effect of platinum-based chemotherapy regimens. Although there are data reporting that hypomagnesemia is associated with worse survival in patients receiving platinum-based chemotherapy or chemoradiotherapy (CRT), this has not been documented in patients with cervical cancer treated with definitive CRT. We hypothesized that in patients with cervical cancer undergoing definitive CRT, on-treatment hypomagnesemia would be associated with longer treatment duration and worse cancer-specific survival (CSS). MATERIALS/METHODS Patients with cervical cancer treated with definitive CRT from 1999 to 2015 were identified from a single cancer center's clinicopathologic database. Lowest on-treatment magnesium value was recorded and categorized as per Common Terminology Criteria for Adverse Events (CTCAE) v5.0 grading (grade 1: <0.7 - 0.5 mmol/L, grade 2: <0.5 - 0.4 mmol/L, grade 3: <0.4-0.3 mmol/L, and grade 4 <0.3 mmol/L). Grade 0 was defined as ≥ 0.7 mmol/L. Treatment duration was defined as the number of days between the first day of radiotherapy until the last day of pelvic treatment (either brachytherapy or pelvic external beam radiotherapy boost). Prolonged treatment was considered as any treatment duration greater than 63 days. CSS for patients with either grade 0-1 or grade ≥ 2 CTCAE v5.0 magnesium toxicity was estimated using the Kaplan-Meier method, and the Peto & Peto modification to the generalized Gehan-Wilcoxon was used to determine statistical significance between groups. Associations with prolonged treatment duration was explored using logistic regression. P-values of <0.05 were considered statistically significant. RESULTS A total of 186 patients were identified; median follow-up was 7 (IQR 2-11) years. 125 (67%) had stage I-II disease and 61 (33%) stage III-IV. Median treatment duration was 51 (IQR 48-57) days. All patients received concurrent weekly cisplatin-based chemotherapy with RT: the majority (n = 133; 72%) received 5 or 6 cycles. 147 (79%) patients received routine IV magnesium infusion with their chemotherapy and 173 (93%) received routine IV mannitol. During treatment the highest CTCAE v5.0 magnesium toxicity score was grade 0-1 in 158 (85%) and grade ≥ 2 in 28 (15%). Magnesium grade ≥ 2 was associated with worse 5-year CSS [grade 0-1: 5yr CSS 67.2%, (95% CI 60.1-75.1); grade ≥ 2: 5yr CSS 50%, (95% CI 34.5-72.4); p = 0.039]. Magnesium status was not associated with an increase in treatment duration [OR 1.465 (95% CI 0.3177 - 6.753); p = 0.625]. CONCLUSION On-treatment hypomagnesemia ≥ grade 2 (CTCAE v5.0) was associated with worse CSS but did not predict longer treatment duration. This is the first study that shows a detrimental survival impact of on-treatment hypomagnesemia in this patient population. These findings highlight the need to ensure adequate monitoring, support and correction of magnesium during definitive CRT.

Abstract
PURPOSE/OBJECTIVE(S) To assess the performance of an artificial intelligence (AI)-based decision support tool under differing thresholds to determine optimal applicator selection in a prospective clinical setting. MATERIALS/METHODS Cervical cancer patients scheduled for high-dose-rate brachytherapy implants with intracavitary tandem and ring (IC) or interstitial tandem and ring (IC/IS) implants in a single tertiary cancer center were eligible for enrollment. Prior to the first brachytherapy implant, a diagnostic MRI was acquired. The clinical target volume and the expected inserted position of the intrauterine tandem and ring were identified and contoured on the T2-MRI. An in-house artificial intelligence-based predicted the need for an IC or IC/IS implant, based on target volume geometric features. For IC/IS implants, an optimal needle arrangement for target coverage was also predicted. Blinded to the AI outcome, a clinical determination was made by the clinician reviewing the MR image. AI algorithm prediction provided a confidence level associated with each decision. The algorithm performance for different confidence thresholds using the IC applicator of 50%, 60%, and 80% was investigated. Performance metrics of the initial clinical determination and the AI prediction were calculated based on the consensus optimal applicator determined from an assessment of planning dosimetry in the first fraction and clinical use for the final brachytherapy implants and fractions. The performance metrics were accuracy, precision, and recall. RESULTS A total of 10 eligible patients were accrued between December 2020 and October 2022. Table 1 shows the initial clinical determination and consensus applicator AI predictions that were made with different confidence thresholds. The optimal confidence threshold (60%) yielded performance scores of 80%, 83.3%, and 83.3% for the accuracy, precision, and recall, respectively. The performance metrics were equivalent for the optimal confidence threshold and the initial clinical decision. CONCLUSION The AI-based decision support tool shows strong predictive results for a clinical brachytherapy application that is important to patient outcome. This prospective study demonstrates that the algorithm's utility is a critical step in using AI-based tools clinically. Further work to determine the optimal brachytherapy applicator, based on treatment planning dosimetry, is required.

Abstract
Reducing radiation treatment dose could improve the quality of life (QOL) of patients with good-risk human papillomavirus–associated oropharyngeal squamous cell carcinoma (OPSCC). Whether reduced-dose radiation produces disease control and QOL equivalent to standard chemoradiation is not proven.

Abstract
The aim of the study was to determine the major source and extent of metal pollution in a residential area of Greater Calcutta. In this area approximately 50,000 people reside in the vicinity of a lead factory that produces lead ingots and lead alloys. Many people, especially children, are affected by lead toxicity. Soils, waters, road dust, leaf dust, leaves and pond sediments were sampled in and around the factory area. Aliquots of the samples were mineralized with nitric acid and hydrogen peroxide in a microwave system. Lead and 19 other elements were quantified in the digests by inductively coupled plasma mass spectrometry. The performance of the procedure was confirmed by analyzing NBS-BCR standard reference soil, leaves, sediment samples. The soils are highly contaminated not only with lead (4.7%), but also with Cd (0.08%), Ag (0.001%), Cu (0.02%), Zn (1.0%), As (1.0%), Mo (0.003%), Sn (0.003%) and Hg (0.03%) (metal concentrations given in parentheses are maximum). Moving away from the smelter, most of metal concentrations, especially Pb, As, Mo, Cu, Hg, Zn, Cd, Sn and Ag, decreased exponentially over increasing distance. In the residential areas near the smelter, notably to the west side of the factory, metal concentrations significantly breached the threshold trigger values set in India by the Central Pollution Control Board (CPCB). Particulate materials from the smelter stack appear to contaminate soils up to at least 0.5 km. However, abnormally high metal levels in the immediate smelter area may be due to primarily fugitive emissions. The surface waters are only contaminated by arsenic ranges from 0.05 to 13.5 mg/l, but the ground water is currently not polluted by lead and arsenic. An appropriate treatment plant with some intervention measures should be taken to save the locality.

Abstract
Effect of A. indica leaf extract on serum enzyme levels (glutamate oxaloacetate transaminase, glutamate pyruvate transaminase, acid phosphatase and alkaline phosphatase) elevated by paracetamol in rats was studied with a view to observe any possible hepatoprotective effect of this plant. It was interesting to observe that serum enzyme levels were much elevated in paracetamol induced animals than in those receiving a combination of paracetamol and lead extract. It is stipulated that the extract treated group was protected from hepatic cell damage caused by paracetamol induction. The findings were further confirmed by histopathological study of liver.

Abstract
Effects of phenformin on blood sugar, serum triglyceride, thrombin time, euglobulin clot lysis time and cardiovascular complications were studied in maturity onset diabetes and in atherosclerotic patients with or without diabetes, for a period of 14-18 months. Phenformin has shown the characteristic properties of an antifibrinopathic agent in that it prolongs thrombin time and enhances fibrinolysis. The hypoglycaemic effect of phenformin was found to be directly related to its antifibrinopathic action. Plasma lipids fell in all cases. Absence of fresh cardiovascular complications and improvement in anginal symptoms were observed. The metabolic, haematological and clinical benefits of phenformin and its limitations in maturity onset diabetes and atherosclerosis may be explained by the effects of the drug upon the thrombin-fibrinogen reaction. These results lend support to the hypothesis of a primary fibrinopathic pathogenesis in maturity onset diabetes mellitus and atherosclerosis.
