Upfront boost to gross disease followed by elective pelvic radiation improves compliance to radiation therapy delivery metrics in locally advanced vulvar cancer. Gynecol Oncol Rep 2024; 52:101362. [PMID: 38495799 PMCID: PMC10940132 DOI: 10.1016/j.gore.2024.101362] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/26/2024] [Revised: 03/04/2024] [Accepted: 03/05/2024] [Indexed: 03/19/2024] Open
Abstract
Locally advanced cancer of the vulva (LACV) is commonly diagnosed in older women (>65 years), and is treated using combined multimodality therapy (CMT) that includes radiation therapy (RT). Compliance to optimal RT metrics, including completion of > 20 fractions, overall treatment duration of < 8 weeks (56 days), and < 1 week intra-treatment break is associated with better disease outcomes. However, published results note that a significant number of patients with LACV do not adhere to these metrics. The aim of our study is to evaluate whether a modified sequence of RT delivery, treating the localized boost volume upfront followed by the larger elective nodal volume is associated with improved compliance to optimal RT delivery metrics.

Double trouble - dual outflow tract obstruction in congenital heart disease: a case report. BMC Cardiovasc Disord 2024; 24:188. [PMID: 38561658 PMCID: PMC10986126 DOI: 10.1186/s12872-024-03842-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2024] [Accepted: 03/13/2024] [Indexed: 04/04/2024] Open
Abstract
BACKGROUND Double chambered right ventricle is a rare congenital heart disease that is characterised by the presence of an anomalous muscle bundle that divides the right ventricle into a low pressure superior (distal) chamber and a high pressure inferior (proximal) chamber. It is found in association with a ventricular septal defect in 90% cases with other associations being tetralogy of Fallot, transposition of great vessels, atrial septal defect and Ebstein's anomaly. On the other hand, subaortic membrane is a form of discrete subaortic stenosis that is characterised by a membranous diaphragm in the subvalvular location of the left ventricular outflow tract. Both of these entities are responsible for causing subvalvular outflow tract obstruction. The occurrence of double chambered right ventricle in association with subaortic membrane is an extremely rare entity with only a few case reports available in the literature. CASE REPORT A 13-year-old male child with history of chest pain and palpitations presented to the outpatient department of a tertiary care center. Transthoracic echocardiography revealed a subaortic membrane producing a pressure gradient across the left ventricular outflow tract with dilatation of the right atrium and right ventricle which could not be fully evaluated on echocardiography. Cardiac computed tomography was then performed which additionally revealed an anomalous muscle bundle coursing across the right ventricle from the septum to the subinfundibular region creating a double chambered right ventricle. The patient was then taken up for reconstruction of right ventricular outflow tract and resection of subaortic membrane. CONCLUSION Right and left outflow tract obstructions are rare congenital lesions which when seen in combination, become even more infrequent. Echocardiography is a robust tool that detects turbulent flow to identify such lesions. However, poor acoustic window may sometimes result in missing these lesions and computed tomography in such situations can play an important role in detection as well as complete preoperative imaging evaluation.

Abstract
PURPOSE/OBJECTIVE(S) Due to manual OAR contouring challenges, various automatic contouring solutions have been introduced. Historically, common clinical auto-segmentation algorithms used were atlas based, which required maintaining a library of self-made contours. Searching the collection was computationally intensive and could take several minutes to complete. Deep learning approaches have shown significant benefits compared to atlas-based methods in improving segmentation accuracy and efficiency in auto-segmentation algorithms. This work represents the first multi-institutional study to describe and evaluate an AI algorithm for auto-segmentation of organs at risk (OARs) based on a deep image-to-image network (DI2IN). MATERIALS/METHODS The AI-Rad Companion Organs RT (AIRC) algorithm (Siemens Healthineers, Erlangen, Germany) uses a two-step approach for segmentation. In the first step, the target organ region in the optimal input image is extracted using a trained Deep Reinforcement Learning network (DRL), which is then used as input to create the contours in the second step based on DI2IN. The study was initially designed as a prospective single-center evaluation. The automated contours generated by AIRC were evaluated by three experienced board-certified radiation oncologists using a 4-point scale where 4 is clinically usable and 1 requires re-contouring. After seeing favorable results in a single-center pilot study, we decided to expand the study to 6 additional institutions, encompassing 8 additional evaluators for a total of 11 physician evaluators across 7 institutions. RESULTS One hundred fifty-six patients and 1366 contours were prospectively evaluated. The 5 most commonly contoured organs were the lung (136 contours, average rating = 4.0), spinal cord (106 contours, average rating = 3.1), eye globe (80 contours, average rating = 3.9), lens (77 contours, average rating = 3.9), and optic nerve (75 contours, average rating = 4.0). The average rating per evaluator per contour was 3.6. On average 124 contours were evaluated by each evaluator. 65% of the contours were rated as 4 and 31% were rated as 3. Only 4% of contours were rated as 1 or 2. 33 organs were evaluated in the study, with 19 structures having a 3.5 or above average rating (ribs, abdominopelvic cavity, skeleton, larynx, lung, aorta, brachial plexus, lens, eye globe, glottis, heart, parotid glands, bladder, kidneys, supraglottic larynx, submandibular glands, esophagus, optic nerve, oral cavity) and the remaining organs having a rating of 3.0 or greater (female breast, proximal femur, seminal vesicles, rectum, sternum, brainstem, prostate, brain, lips, mandible, liver, optic chiasm, spinal cord, spleen). No organ had an average rating below 3. CONCLUSION AIRC performed well with greater than 95% of contours accepted by treating physicians with no or minor edits. It supported a fully automated workflow with the potential for time savings and increased standardization with the use of AI-powered algorithms for high quality OAR contouring.

Abstract
PURPOSE/OBJECTIVE(S) Deep Learning approaches have shown significant benefits compared to atlas-based methods in improving segmentation accuracy and efficiency in auto-segmentation algorithms. The AI-Rad Companion Organs RT pelvic nodal auto-segmentation feature was trained and developed for use in the male pelvis. There is no real-world data on its usability in male pelvis and whether it can be used for female pelvic nodal anatomy. This work represents the first multi-institutional study to describe and evaluate an AI algorithm for auto-segmentation of the pelvic nodal region in female patients based on a deep image-to-image network (DI2IN). MATERIALS/METHODS The AIRC algorithm uses a two-step approach for segmentation. In the first step, the target organ region in the optimal input image is extracted using a trained Deep Reinforcement Learning network (DRL), which is then used as input to create the contours in the second step based on DI2IN. We retrospectively evaluated AIRC pelvic nodal auto-segmentation in both male and female patients treated at our network of institutions. The automated pelvic nodal contours generated by AIRC were evaluated by one board-certified radiation oncologist, specializing in prostate and gynecologic malignancies. A 4-point scale was used, where 4 is clinically usable and 1 requires re-contouring. Pelvic nodal regions included the right and left side of the common iliac, external iliac, internal iliac, obturator and midline presacral nodes. A chi-squared test was then used to compare the scores of male and female pelvic nodal cases. RESULTS Fifty-two female and 51 male patients were included in the study, representing a total of 468 and 447 pelvic nodal regions, respectively. 96% (450 pelvic nodal contours) and 99% (443 pelvic nodal contours) required no or minor edits for female and male patients, respectively (p = 0.004). The right internal iliac was the only nodal group with a statistically significant difference between female (92% requiring no or minor edits) and male (100% requiring no or minimal edits) patients, p = 0.04. The percentage of patients requiring no, or minor edits was 87% (45 patients) and 92% (47 patients) for female and male patients, respectively (p = 0.36). CONCLUSION AIRC pelvic nodal auto-segmentation performed very well in both male and female pelvic nodal regions, with the male pelvic nodal regions performing better especially in the right internal iliac nodal group. It is usable in female pelvic nodal regions, with 96% of contours requiring no or minor edits. As auto-segmentation becomes more widespread, it may be important to have equal representation from all genders in training and validation of auto-segmentation algorithms.

Abstract
PURPOSE/OBJECTIVE(S) As the human papilloma virus (HPV) pandemic evolves and life expectancy increases, the number of older adults with oropharyngeal squamous cell carcinoma (OPSCC) continues to increase. However, there is a paucity of data regarding the fastest growing subset of this population: octogenarians (OGs). We sought to understand differences in treatment tolerability and clinical outcomes between septuagenarians (SGs) and OGs with OPSCC. MATERIALS/METHODS We identified SGs (age 70-79) and OGs (age 80-89) with OPSCC from a cohort of older adults with nonrecurrent, nonmetastatic head and neck squamous cell carcinoma (HNSCC) treated curatively from 2007-2020. We compared demographics, treatment characteristics and toxicities using Fischer's exact test. Time-to-event outcomes, overall survival (OS), locoregional control (LRC), and disease-specific survival (DSS), were evaluated using the Kaplan-Meier method. RESULTS Of 293 patients (age 70-89) with HNSCC, 39% (n = 114) had OPSCC: 93 SGs (median age: 73; interquartile range [IQR]: 71-76), and 21 OGs (median age: 81, IQR: 80-84). The median follow-up for included patients was 2.4 years; 82% were male, 64% white, 48% > 20 pack year smoking history, 37% ECOG 1. Patients had AJCC 8th edition Stage: I (27%); II (33%); III (18%); IV (22%) OPSCC. Treatment consisted of adjuvant radiation (RT) (19%), adjuvant chemoradiation (CRT) (8%), surgery alone (6%), induction/concurrent CRT (27%), concurrent CRT (28%), or RT (12%), with no significant differences in stage or treatment modalities noted between SGs and OGs. Of note, 69% of SGs and 76% of OGs were HPV+. Among 107 patients who received any RT, 24% experienced a treatment interruption (19% of SGs vs. 48% of OGs, p = 0.001) and 2 patients (both HPV- SGs) died on treatment due to unrelated health conditions. Percutaneous endoscopic gastrostomy (PEG) tubes were placed prior to or during treatment in 43% of SGs and 62% of OGs, with OGs more likely to have a PEG placed during treatment (p = 0.025). There was no difference in the prevalence of late (> 6 months) CTCAE grade 2+ dysphagia (36%) or xerostomia (31%) between SGs and OGs. Estimated 3-year LRC, DSS, and OS were not significantly different between SGs (LRC:85%; DSS:87%; OS:76%) and OGs (LRC: 81%; DSS:94%; OS: 55%, p-values: 0.98, 0.42, 0.052, respectively). However, HPV+ disease significantly increased estimated 3-year OS for both SGs (HPV+: 84%; HPV-: 56%, p = 0.0006) and OGs (HPV+: 68%; HPV-: 20%, p = 0.008). CONCLUSION In our cohort, OGs had a higher proportion of HPV+ OPSCC, which was associated with improved OS. This finding may provide insight into the latency of the virus. While there were similar amounts of toxicities among SGs and OGs, OGs more frequently underwent PEG tube placement and experienced more treatment interruptions. Given high rates of HPV+ OPSCC in OGs, our findings suggest that de-escalation strategies should be further investigated to improve tolerability and maximize outcomes for this neglected population.

Abstract
PURPOSE/OBJECTIVE(S) Peer review is an essential step in clinical quality assurance and can impact patient safety and treatment outcomes. Most published data on peer review is from developed nations, with little data on peer review from low middle income countries (LMIC). Major challenges to peer review can include a lack of time, expertise and commitment from team members. With increasing access to advanced technology in LMIC, peer review is becoming more important to maintain quality and standard of care. We evaluated cloud-based e- peer review (Varian) in our network of hospitals in India with an aim to see feasibility and impact on care. MATERIALS/METHODS Four of 15 centers across India were selected for this pilot study. All team members were trained on the platform prior to implementation. New cases for the week treated with definitive intent were selected by the dosimetrist. The link to the cases were sent through email to reviewing physicians. Various aspects which were reviewed for each case were.1) Work up & staging (Documents were scanned and loaded).2) Treatment intent & prescription.3) Target contours.4) Normal Organ at risk contours.5) Dose- Volume -Histogram (DVH) with clinical goals attached. Cases were marked as "Not Appropriate", "Appropriate", "Appropriate with minor finding", "Represent with major revisions" as per volume and plan review. RESULTS Over a period of 2 months, a total of 80 cases underwent e-Peer Review at our network of hospitals prior to the start of treatment. Median turnover time (like from link sent to time to completion of review) was 48 (6-360) hours. Mean time taken by physician for review was 9 minutes (range 3 to15). 31.2% of cases were accepted without any changes, 51.9 % had a minor change and 16.9 % cases had major changes. Most frequent reason of major changes was contouring corrections 16.9%. 31% of major changes underwent recontouring and replanning before initiation of treatment. CONCLUSION Peer review was feasible in our network through this e-peer review system, with average turnover time and mean time taken for review of 48 hours & 9 min respectively. Peer review led to significant changes which could impact patient care delivery and outcome. The ability to review cases asynchronously via this cloud-based e-peer review system, helped to ease the burden of scheduling between treating and reviewing physician. We plan to implement this across the remaining centers in our network.

Abstract
BACKGROUND Asymptomatic/presymptomatic COVID-19 affected individuals who may appear healthy during blood donor screening can donate blood despite being infective. Most blood donors in India are relatives/friends/acquaintances of patients, who under peer pressure overlook the donor selection process, which can significantly impact the transfusion safety. AIMS The prevalence of severe acute respiratory syndrome-related coronavirus 2 (SARS-CoV-2) antibodies among blood donors was assessed, along with the possible transmissibility of SARS-CoV-2 virus in transfusion recipients of blood components prepared from sero-reactive blood donors. SETTINGS AND DESIGN A prospective cross-sectional study was conducted among eligible blood donors from November-2020 to April 2021. METHODS 1500 blood donors were tested for SARS-CoV-2 IgG antibodies. Sero-reactive donors were followed-up telephonically to inquire about risk factors prior to donation or appearance of COVID-19 related symptoms postdonation. Patients transfused with blood components from seroreactive donors were also followed up for posttransfusion symptoms suggestive for COVID-19. Descriptive analysis was done for the donor and patient follow-up data. RESULTS A total of 452 (30.1%) donor were reactive, with median S/CO ratio of 2.8 (interquartile range 1.5-5.5). Risk factors such as travel, contact, or quarantine were significantly higher among reactive donors. History of diabetes and/or hypertension was associated with seroreactivity. Total 516 patients were transfused with blood components from these seroreactive donors. Three patients developed fever after transfusion, one of which was found to be PCR positive after 4 days of transfusion. CONCLUSION Sero-reactivity rate among blood donors was lower than the general population. Optimum blood donor screening strategies can help decrease the possibility of blood collection from infected blood donors.

Abstract
Background It is critical to identify high-risk groups among children with COVID-19 from low-income and middle-income countries (LMICs) to facilitate the optimum use of health system resources. The study aims to describe the severity and mortality of different clinical phenotypes of COVID-19 in a large cohort of children admitted to tertiary care hospitals in India. Methods Children aged 0-19 years with evidence of SARS-CoV-2 infection (real time polymerase chain reaction or rapid antigen test positive) or exposure (anti-SARS-CoV-2 antibody, or history of contact with SARS-CoV-2) were enrolled in the study, between January 2021 and March 2022 across five tertiary hospitals in India. All study participants enrolled prospectively and retrospectively were followed up for three months after discharge. COVID-19 was classified into severe (Multisystem Inflammatory Syndrome in Children (MIS-C), severe acute COVID-19, 'unclassified') or non-severe disease. The mortality rates were estimated in different phenotypes. Findings Among 2468 eligible children enrolled, 2148 were hospitalised. Signs of illness were present in 1688 (79%) children with 1090 (65%) having severe disease. High mortality was reported in MIS-C (18.6%), severe acute COVID-19 (13.3%) and the unclassified severe COVID-19 disease (12.3%). Mortality remained high (17.5%) when modified MIS-C criteria was used. Non-severe COVID-19 disease had 14.1% mortality when associated with comorbidity. Interpretation Our findings have important public health implications for low resource settings. The high mortality underscores the need for better preparedness for timely diagnosis and management of COVID-19. Children with associated comorbidity or coinfections are a vulnerable group and need special attention. MIS-C requires context specific diagnostic criteria for low resource settings. It is important to evaluate the clinical, epidemiological and health system-related risk factors associated with severe COVID-19 and mortality in children from LMICs.

Critical appraisal of knowledge, attitude and practice studies for blood donation in India. Transfus Med 2023.

Abstract
BACKGROUND AND OBJECTIVES A critical appraisal of the literature helps to assess the strength and weakness of the research and suggests ways to improve future research. Our aim was to critically appraise the knowledge, attitude, and practice (KAP) studies conducted in India for blood donation. MATERIALS AND METHODS Of 70 articles identified in our search on PubMed, Scopus and Google Scholar, 32 were assessed for quality using an appraisal tool for cross-sectional studies (AXIS) and questionnaire items. RESULTS Quality assessment revealed that only 6 of 32 studies had acceptable reporting (≥80% score on the AXIS tool). The most frequently identified shortcomings were failure to address the non-responders, lack of justification for sample size, assessment of outcome variables and demographic results for the survey. Our evaluation of questionnaires revealed that knowledge for need for blood donation, its benefits and site/place for blood donation were assessed by very few studies. With this, issues such as parental/family consent, religious beliefs, and indifference to blood donation process were amongst the common reasons for non-donation. Many studies also failed to ask questions related to procedural information/instructions, which are necessary for promoting voluntary blood donations. CONCLUSION Most published KAP studies for blood donation in India were not appropriately described, especially the methodology and result section. These deficiencies could have led to suboptimal interpretation of the prevalent issues. Use of an open-ended and validated KAP questionnaire with a problem-based approach and inclusion of participants from various socio-cultural backgrounds is required for good quality of evidence.

The nonmetabolizable glucose analog 2-deoxy-D-glucose (2-DG) has shown promising pharmacological activities, including inhibition of cancerous cell growth and N-glycosylation. It has been used as a glycolysis inhibitor and as a potential energy restriction mimetic agent, inhibiting pathogen-associated molecular patterns. Radioisotope derivatives of 2-DG have applications as tracers. Recently, 2-DG has been used as an anti-COVID-19 drug to lower the need for supplemental oxygen. In the present review, various pharmaceutical properties of 2-DG are discussed.

Abstract
The 3D edge-enhancing gradient-echo (EDGE) MR imaging sequence offers superior contrast-to-noise ratio in the detection of focal cortical dysplasia. EDGE could benefit from 7T MR imaging but also faces challenges such as image inhomogeneity and low acquisition efficiency. We propose an EDGE-MP2RAGE sequence that can provide both EDGE and T1-weighted contrast, simultaneously, improving data-acquisition efficiency. We demonstrate that with sequence optimization, EDGE images with sufficient uniformity and T1-weighted images with high gray-to-white matter contrast can be achieved.

Abstract
Three non-fused A-D-A'-D-A π-conjugated metal-free small molecules BT-IT1, BT-IBT2 and BT2F-IBT3 have been synthesized and their absorption characteristics and redox properties, as well as charge carrier mobilities have been investigated. The resultant molecules exhibited broad absorption in the range of 325-600 nm in solutions and in thin films the absorption range is 350-700 nm. These new conjugated small molecules showed low-lying HOMO energy levels (-5.49 to -5.50 eV), deep LUMO energy levels (-3.67 to -3.69 eV) and narrow bandgaps of (Eg CV ) ∼0.79 eV. Appreciable electron mobilities for compounds BT-IBT2 and BT2F-IBT3 were 4.56×10-3 and 1.12×10-3 cm2 V-1 s-1 , respectively, obtained by space-charge limited current (SCLC) measurements. Additionally, excellent photocatalytic performances of BT-2T (6), BT2F-2T (10), BT-IT1, BT-IBT2 and BT2F-IBT3 for highly selective oxidation of thioanisole to desired sulfoxides under visible light irradiation were observed.

Abstract
BACKGROUND AND PURPOSE The trochlear nerve has traditionally been difficult to identify on MR imaging. The advent of 7T MR imaging promises to greatly benefit visualization of small structures due to gains in the signal-to-noise ratio allowing improved spatial resolution. We investigated the utility of a clinically feasible ultra-high-resolution 7T MR imaging protocol for identification of the trochlear nerve, as well as assessment of normal trochlear nerve anatomy. MATERIALS AND METHODS Coronal high-resolution 2D T2-weighted TSE images used in a 7T epilepsy protocol of 50 subjects at our institution were reviewed by 2 independent radiologists for visualization of the trochlear nerve at the nerve origin and cisternal, tentorial, and cavernous segments. The frequency of nerve visibility within these segments and their anatomy were documented, and disagreements were resolved by joint review. RESULTS Of the 100 nerves reviewed in 50 subjects, at least 2 segments of the trochlear nerve from the brainstem to the cavernous sinus were identified in 100% of cases. The origins from the brainstem and cisternal segment were visible in 65% and 93% of nerves, respectively. The trochlear nerve was identified at the trochlear groove in 100% of cases and in the posterior wall of the cavernous sinus in 74% of cases. CONCLUSIONS Coronal high-resolution 2D TSE at 7T reliably identified the trochlear nerve throughout its course and is a promising tool for imaging patients with suspected trochlear nerve pathology.

Abstract
OBJECTIVES This study aimed to assess the association of blood donor variables on the outcome of patients undergoing cardiac surgery. STUDY DESIGN AND METHODS A retrospective observational study was conducted on patients who had cardiac surgery between January 2018 and December 2020. Blood donor characteristics such as age (≤ or >30 years), sex, and body mass index (BMI) (≤ or >25 kg/m2) were analyzed for association with patient outcomes (length of hospital stay (LOS), mortality, and readmission). Sex matching was done as fully match, fully mismatch, and partial mismatch. Cox regression and Linear regression models were used to study the association with mortality and readmission, and LOS. RESULTS During the study period, 5788 patients had cardiac surgery; receiving a total of 20,348 red cell units. Of which, 522 (9%) died, 531 (9.2%) re-admitted and median LOS was 11 days (IQR 7-18). BMI >25 kg/m2 (β, 2.96; p = 0.000), female to male transfusion (partial mismatch: β, 4.42; p = 0.001; fully mismatch: β, 9.0; p = 0.02) negatively affected LOS. BMI >25 kg/m2 (HR, 2.07; p = 0.00) and partial mismatch transfusion to male patients (HR, 1.60; p = 0.01) increased mortality. Fully mismatch transfusion to female patients (HR, 1.24; p = 0.01) and partial mismatch to male patients (HR, 1.86; p = 0.01) increased readmission. No association of donor age on patient outcome was observed. DISCUSSION Blood donor sex, and BMI can influence mortality and LOS in cardiac surgery patients. The use of computer tools to match the patient's and donor's characteristics can assist to eliminate these types of adverse consequences.

Background
Cardiovascular risk scores serve as a useful tool to reinforce the importance of lifestyle modifications and treatment compliance. Yet, there remains a gap between advice by the physician and its implementation by the patient. Digital therapeutics (DTx) as a technology based approach can help bridge this gap. In this context, knowing the quantum of change in disease outcomes and long term cardiovascular risk after DTx implementation can be helpful in persuading the patients for lifestyle interventions.
Purpose
To evaluate the change in cardiovascular risk scores in hypertensive patients after a digital therapeutic intervention.
Method
We conducted a prospective, single arm, 12-week intervention trial at two primary care sites in India. A total of 125 subjects within the age group of 30-65 years with primary hypertension (≥ 140/90 mmHg) were enrolled. They were provided DTx intervention which consisted of modification in diet, physical activities, self-monitoring and health education superimposed on behavior science theories. Atherosclerotic Cardiovascular Disease (ASCVD) risk scores from Pooled Cohort Equation were calculated for all subjects before & after the DTx intervention and the change in score was assessed.
Results
We received the data of 116 patients having a mean age of 47.66 ± 9.47 years and mean BMI of 27.20 ± 4.77 Kg/m². After DTx intervention, the change in mean systolic blood pressure, among other ASCVD equation parameters, was -26.38 mmHg (154.77 vs 128.39 mmHg, P<0.001). The corresponding post-intervention 10-year mean ASCVD risk score for the sample population decreased by 4.74% (11.86% vs 7.12%, P<0.001). The 10-year mean relative risk of ASCVD decreased by 39.95 %. Similarly ASCVD lifetime risk score decreased by 3.04% (49.54% vs 46.50%, P<0.001), amounting to mean relative risk reduction of 6%. Female subjects (n=60) showed higher 10-year mean ASCVD risk reduction of 5.70% (11.70% vs 6.00%, P<0.001), compared to male subjects (n=56) who showed 10-year mean ASCVD risk reduction of 3.76% (12.06% vs 8.30%, P<0.001). This amounted to a relative risk reduction of 48.69% and 30.71% for female & male subjects, respectively. Patients with stage 1 hypertension (n=82) showed a reduction in 10-year mean ASCVD risk of 2.86% (9.90% vs 7.04%, P<0.001). Patients with stage 2 (n=30) & stage 3 hypertension (n=4) achieved higher 10-year mean ASCVD risk reduction of 8.67% (16.07% vs 7.40%, P<0.001) & 13.6% (20.88% vs 7.20%, P=.006).
Conclusion
Digital therapeutics enabled intervention has caused a significant decrease in 10-year & lifetime ASCVD risks which can eventually lead to a decrease in cardiovascular complications, morbidity and mortality. Therefore, such intervention programs should be further explored and studied.

Background
Digital therapeutics (DTx) has emerged as a new approach in recent years making use of connected devices, smartphone software and electronic communication tools to help manage chronic cardiovascular diseases such as hypertension. Considering its nascent stage, many questions still remain with respect to its applicability, effectiveness and limitations.
Purpose
Assess the effectiveness of digital therapeutic intervention in controlling blood pressure in Indian patients with primary hypertension
Methods
We conducted a prospective, 12 week, single arm, interventional study, including 125 subjects at multiple sites in India. Subjects with uncontrolled primary hypertension (≥140 mmHg systolic and/or ≥90 mmHg diastolic) in the age group of 30-65 years who were under routine antihypertensive treatment were enrolled. They were provided supplementary DTx intervention comprising of smartphone application based personalized management of diet, exercise, self monitoring and health education by nutritionists and health coaches. Efficacy endpoints such as blood pressure (BP), body mass index (BMI), lipids, etc. were measured before and after the intervention.
Results
A total of 122 subjects who completed the trial had mean age of 47.44 ± 9.43 years, comprising 58 (48%) male and 64 (52%) female patients and mean BMI of 27.21 ±4.7 kg/m². Post-intervention change in mean systolic BP (SBP) was -25.61 mmHg (95% CI 22.55 - 28.66, 154.98 mmHg vs 129.37 mmHg, P<.001). The post-intervention change in mean diastolic BP (DBP) was -18.62 mmHg (95% CI 16.29 - 20.96, 100.04 mmHg vs 81.42 mmHg, P<.001). Patients with stage 1 hypertension (69.6%) achieved mean systolic reduction of 20.87 ± 13.9 mmHg, (148.54 mmHg vs 127.67 mmHg, P<.001). The patients with stage 2 (27.04%) and stage 3 (3.27%) hypertension achieved a higher mean SBP reduction of 34.67 ± 15.19 mmHg (167.24 mmHg vs 132.58 mmHg, P<.001) and 51.5 ± 40.45 mmHg (190.75 mmHg vs 139.25 mmHg, P=.084), respectively. Male and female patients showed almost similar reduction in systolic BP of 25.47 ± 14.72 and 25.73 ± 19.39 mmHg, respectively. Also, the subjects with other chronic comorbidities (23.9%) achieved a mean systolic BP reduction of 29.51 ± 15.25 mmHg.
A total of 79.51% (n=97) patients achieved the SBP <140 mmHg, while 59.84% (n=73) patients achieved SBP <130 mmHg. Combining both the systolic and diastolic targets together, 65.57% (n=80) patients achieved the target of <140/90 mmHg, while ESC/ESH 2018 recommended BP target of <130/80 mmHg was achieved by 31.15% (n=38) patients.
Conclusion
The implementation of Digital therapeutic application integrated with primary healthcare resulted in significant reduction in blood pressure in participants with uncontrolled hypertension. Greater improvement was observed in participants with higher baseline blood pressure.

Abstract
DUNE is a dual-site experiment for long-baseline neutrino oscillation studies, neutrino astrophysics and nucleon decay searches. ProtoDUNE Dual Phase (DP) is a 6 × 6 × 6 m 3 liquid argon time-projection-chamber (LArTPC) that recorded cosmic-muon data at the CERN Neutrino Platform in 2019-2020 as a prototype of the DUNE Far Detector. Charged particles propagating through the LArTPC produce ionization and scintillation light. The scintillation light signal in these detectors can provide the trigger for non-beam events. In addition, it adds precise timing capabilities and improves the calorimetry measurements. In ProtoDUNE-DP, scintillation and electroluminescence light produced by cosmic muons in the LArTPC is collected by photomultiplier tubes placed up to 7 m away from the ionizing track. In this paper, the ProtoDUNE-DP photon detection system performance is evaluated with a particular focus on the different wavelength shifters, such as PEN and TPB, and the use of Xe-doped LAr, considering its future use in giant LArTPCs. The scintillation light production and propagation processes are analyzed and a comparison of simulation to data is performed, improving understanding of the liquid argon properties.

Abstract
BACKGROUND AND PURPOSE Parry-Romberg syndrome is a rare disorder characterized by progressive hemifacial atrophy. Concomitant brain abnormalities have been reported, frequently resulting in epilepsy, but the frequency and spectrum of brain involvement are not well-established. This study aimed to characterize brain abnormalities in Parry-Romberg syndrome and their association with epilepsy. MATERIALS AND METHODS This is a single-center, retrospective review of patients with a clinical diagnosis of Parry-Romberg syndrome and brain MR imaging. The degree of unilateral hemispheric atrophy, white matter disease, microhemorrhage, and leptomeningeal enhancement was graded as none, mild, moderate, or severe. Other abnormalities were qualitatively reported. Findings were considered potentially Parry-Romberg syndrome-related when occurring asymmetrically on the side affected by Parry-Romberg syndrome. RESULTS Of 80 patients, 48 (60%) had brain abnormalities identified on MR imaging, with 26 (32%) having abnormalities localized to the side of the hemifacial atrophy. Sixteen (20%) had epilepsy. MR imaging brain abnormalities were more common in the epilepsy group (100% versus 48%, P < .001) and were more frequently present ipsilateral to the hemifacial atrophy in patients with epilepsy (81% versus 20%, P < .001). Asymmetric white matter disease was the predominant finding in patients with (88%) and without (23%) epilepsy. White matter disease and hemispheric atrophy had a higher frequency and severity in patients with epilepsy (P < .001). Microhemorrhage was also more frequent in the epilepsy group (P = .015). CONCLUSIONS Ipsilateral MR imaging brain abnormalities are common in patients with Parry-Romberg syndrome, with a higher frequency and greater severity in those with epilepsy. The most common findings in both groups are white matter disease and hemispheric atrophy, both presenting with greater severity in patients with epilepsy.

Abstract
Giant celiac artery aneurysm is a rare entity. We describe a case of a 45-year-old male with chronic kidney disease who presented with abdominal pain for the past 6 months. CT showed a celiac artery aneurysm of size 6×6.2cm involving the common hepatic artery and compressing the portal vein posteriorly. During the procedure the supra celiac aorta was exposed, and the neck of the aneurysm was identified. After taking control of branches of the celiac and common hepatic arteries, the neck of the aneurysm was clamped and divided. In view of diminished flow in the hepatic arteries aorto hepatic bypass was done using PTFE graft from supra celiac aorta to right hepatic artery; as there was retrograde flow from the left hepatic artery it was ligated. Post operatively the patient's liver functions were normal, and he was followed up by Doppler sonography which detected good flow in the hepatic artery distal to anastomosis. Celiac artery aneurysms are rare, and management options vary from the endovascular to surgery; regardless of the approach used, revascularisation is needed if there is no adequate collateral flow.

Abstract
Intraductal papillary neoplasm of the bile duct (IPN-B) is a rare preinvasive intraductal pathology of the biliary tract. It should be differentiated from other more common benign or malignant causes of biliary obstruction and dilatation such as calculi or cholangiocarcinoma because the management and prognosis of this condition differs significantly. This case report describes a case of IPN-B in a 45-year-old female patient who presented with non-specific complaints of chronic abdominal pain without jaundice for three months.

Abstract
Background Tryptophan, an essential amino acid found in many protein-based foods, has been involved in the pathogenesis of mood disorders and celiac disease (CeD). However, dietary tryptophan consumption has not been investigated in CeD. Aims To estimate 1) differences in tryptophan content in food consumed in CeD patients compared to matched healthy controls (HC), and 2) whether consumption of tryptophan is associated with the presence of anxiety and depression in patients with CeD. Methods This prospective observational study examined adult patients with a diagnosis of CeD, based on positive specific serology and confirmed by duodenal biopsies, enrolled in the Celiac Registry at McMaster University. A group of sex matched HC were recruited from within the community. Participants completed several questionnaires to evaluate, gastrointestinal symptoms (GSRS), Anxiety and Depression (HADS), and dietary intake of tryptophan (Modified Food Frequency Questionnaire). In addition, CeD patients were assessed for celiac disease activity (CSI), gluten-free diet (GFD) adherence (CDAT) and nutritional status. HADs >11 denoted significant anxiety or depression. Cut-off for low vs high amount of tryptophan content in food was established based on the median tryptophan food content in the HC population. Results A total of 443 participants were enrolled in the study; 222 with CeD and 221 controls. The majority of participants were female (74.3%) and the adherence to the GFD was very good (Median CDAT=13; IQR 11–15). The CeD patients were older than HC (Median age, yrs. CD= 40 vs HC= 35; p<0.01). Patients with CeD consumed higher amount of tryptophan compared with HC (Median tryptophan g/day CeD=4.41 vs HC=3.31; p<0.01). There were 157 active CeD patients (CSI ≧ 30). There was no difference in tryptophan consumption between patients with and without active CeD (OR=1.021; 95%CI 0.86–1.21; p=0.88). There was no association between tryptophan consumption and gastrointestinal symptoms or depression scores. Fifteen % of the overall population and 18% of the CeD population had anxiety. There was an increased risk of anxiety in the overall population that consumed low amount of tryptophan (OR=1.87; 95%CI 1.01–3.11; p=0.04), and the risk was greater in the CeD population (OR=4.57; 95%CI 1.26–16.41; p<0.01). Conclusions Consumption of food with lower amounts of tryptophan in patients with CeD is associated with significant anxiety, which may influence disease management. Future studies should evaluate whether increasing tryptophan in the diet compared to supplements improves outcomes in CeD population, especially in those with anxiety. Funding Agencies None

Abstract
BACKGROUND: Tobacco and TB are the world´s two greatest public health problems. Exposure to tobacco has been shown to be associated with higher risk of acquiring TB and adverse outcomes such as relapse and TB mortality.OBJECTIVE: To assess and compare self-reported tobacco quit status and biochemically verified cotinine levels among TB patients at different time intervals among two study groups.METHODS: A cluster, randomised controlled trial was conducted on TB patients attending DOTS centres in Delhi, India, who reported using tobacco in any form. Participants were assigned into one of two treatment groups. Centres were randomly assigned to two intervention groups: 1) integrated intervention using behavioural counselling with nicotine replacement therapy (NRT) gum, and 2) intervention using behavioural counselling alone (50 each in intervention and control group). The subjects were followed at Week 1, Month 1, Month 3 and Month 6 for tobacco cessation.RESULTS: At the end of 6 months, patients who received the integrated intervention had significantly higher rate of success in quitting tobacco than those who received the conventional TB treatment alone (78.7% vs. 57.8%; P < 0.03).CONCLUSION: DOTS with tobacco use dependence treatment was successful in our study in helping TB patients to quit tobacco dependence and should therefore be offered to every tobacco user.

Family vitiligo impact scale: A scale to measure the quality-of-life of family members of patients with vitiligo. Indian J Dermatol Venereol Leprol 2021; 88:32-39. [PMID: 34379960 DOI: 10.25259/ijdvl_928_20] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2020] [Accepted: 04/01/2021] [Indexed: 11/04/2022]
Abstract
BACKGROUND Vitiligo places a significant psycho-social burden on caregivers and family members. AIMS The aim of the study was to develop and preliminarily validate a scale to measure the psychosocial impact of vitiligo on adult family members. METHODS Themes that emerged from qualitative interviews and a focus group discussion with family members were used to generate items for a preliminary scale, followed by pre-testing and scale development. The new scale was then tested with two comparator scales and a global question. RESULTS A preliminary scale with 32 items was pilot tested on 30 participants. Following this, the scale was condensed to 16 items in 12 domains that were administered to 159 participants. Scale scores ranged from 0 to 48 with a mean of 19.75 ± 12.41. The scale had excellent internal consistency with Cronbach's alpha coefficient of 0.92 (0.70-0.95) and also showed good test-retest reliability at two weeks (r = 0.946). The scale showed criterion, convergent and known group validity. LIMITATIONS It was conducted in a large teaching hospital which may have resulted in selection of patients with persistent or progressive disease and more worried family members. Vitiligo is highly stigmatized in our country and the performance of the scale may need to be evaluated in other communities and cultures as well where stigma is less oppressive. CONCLUSION Family Vitiligo Impact Scale appears to be an easy-to-complete, reliable and valid instrument to measure the psychosocial impact of vitiligo in family members of patients. It may be useful as an outcome measure in both clinical and research settings.

Absence of Meckel Cave: A Rare Cause of Trigeminal Neuralgia. AJNR Am J Neuroradiol 2021; 42:1610-1614.

Abstract
Trigeminal neuralgia is a debilitating condition with numerous etiologies. In this retrospective case series, we report a cohort of patients with a rarely described entity, absence of Meckel cave, and propose this as a rare cause of trigeminal neuralgia. A search of the electronic medical record was performed between 2000 and 2020 to identify MR imaging reports with terms including "Meckel's cave" and "hypoplasia," "atresia," "collapse," or "asymmetry." Images were reviewed by 2 blinded, board-certified neuroradiologists. Seven cases of the absence of Meckel cave were identified. Seven patients (100%) had ipsilateral trigeminal neuralgia and ipsilateral trigeminal nerve atrophy, suggesting an association between absence of Meckel cave and trigeminal neuralgia. Absence of Meckel cave is a rare entity of unknown etiology, with few existing reports that suggest the possibility of an association with trigeminal neuralgia. Its recognition may have important implications in patient management. Future studies and longitudinal data are needed to assess treatment outcomes and added risks from surgical intervention in these patients.

Abstract
BACKGROUND Handwashing has been widely accepted as the simplest protection against communicable diseases. However, despite proven effectiveness and cost-efficiency, adoption of regular handwashing is still poor in developing countries. As children in school-going age are vulnerable and continue to suffer from preventable illnesses, this study aims to spot barriers to handwashing among children while simultaneously recognizing the influencing factors to aid the solutions narrative for effective water, sanitation and hygiene (WASH) strategies. METHODS A school-based cross-sectional, mixed-method study was conducted in Ballabhgarh block, Faridabad district, India. A predesigned, pretested, structured questionnaire was administered to 106 class V students in five randomly selected rural government primary schools. Due permissions, consent and ethical clearances were taken. RESULTS The majority (>91%) of children were found to have low illness threat perception. The inability to visually see germs came out as one of the biggest barriers (46%) that were preventing children from practicing regular handwashing. Family, teachers and peers were found to be the most important sources of information for children and not any particular media channel. In fact, role of peers was found to be critical as 72% children said that they would wash hands if their friends were also washing hands. CONCLUSION This study suggests children's need for visible proof of germs and associated casual attitude toward illness threat as a hitherto unexplored potential barrier to practicing regular handwashing. In addition, the human channel of communication seems to be the most relevant regarding public health messaging in rural heartlands. Despite 100% penetration of mobile phones and commonplace presence of television, it is the community ecosystem that is still the most trusted sources of information and influence. The unique role of peers found in this study could have strategic implications for future behaviour change interventions making a case for peer-to-peer behaviour modeling.
