The Past, Present, and Future of the Brain Imaging Data Structure (BIDS).

The Brain Imaging Data Structure (BIDS) is a community-driven standard for the organization of data and metadata from a growing range of neuroscience modalities. This paper is meant as a history of how the standard has developed and grown over time. We outline the principles behind the project, the mechanisms by which it has been extended, and some of the challenges being addressed as it evolves. We also discuss the lessons learned through the project, with the aim of enabling researchers in other domains to learn from the success of BIDS.

Initial Experiences in Adolescents and Young Adults with T-Cell Acute Lymphoblastic Leukemia/Lymphoma Treated with the Modified BFM 2002 Protocol in a Resource-Constrained Setting.

Prutha Jinwala T-cell acute lymphoblastic leukemia/lymphoblastic lymphoma (T-ALL/LBL) in adolescents and young adults (AYAs) is a clinically aggressive malignancy and life-threatening at diagnosis. Intensive chemotherapy protocols, inspired by the Berlin-Frankfurt-Münster (BFM) regimen, along with central nervous system (CNS) prophylaxis, have achieved a 75 to 85% 5-year disease-free survival rate. However, in cases of marrow and CNS relapses, second-line chemotherapy is usually ineffective. This study aimed to assess the safety and efficacy of the BFM 2002 protocol and to correlate clinical profiles and prognostic factors with survival outcomes in AYA T-ALL/LBL patients. We retrospectively analyzed data from T-ALL/LBL patients treated at the Department of Medical Oncology, Sri Aurobindo Institute of Medical Sciences (SAIMS), Indore, between 2018 and 2021. Twenty-one patients aged 15 to 29 years were studied for their clinical course and laboratory parameters over 36 months. Diagnosis and risk stratification were performed following the guidelines of the BFM 2002 protocol. All patients received treatment and monitoring according to this pediatric-inspired protocol. The median age of the patients was 17 years (range: 15-28 years). Eleven patients presented with mediastinal lymph node enlargement, 10% exhibited CNS involvement, and none had testicular involvement. Eleven patients had marrow blasts greater than 25%, indicative of acute lymphoblastic leukemia. All 21 patients were treated according to the intensive modified BFM 2002 protocol and achieved morphological remission after a median follow-up of 24 months (range: 18-36 months). Seventeen patients achieved minimal residual disease (MRD) negativity post-induction. MRD at day 33 showed a significant association with the probability of disease relapse ( p = 0.0015). There were five deaths (24%), one due to toxicity and four due to relapse. The study recorded an 18-month overall survival of 76%. These results were achieved despite financial constraints. Data were entered into a spreadsheet, and statistical analysis was performed using IBM SPSS version 23. Continuous data are presented as ranges and medians, while categorical variables are shown as percentages and numbers. A chi-squared test for association, with a significance level set at p < 0.05, was conducted as indicated. AYA T-ALL/LBL requires intensive treatment regimens. With biological characterization of LBL/ALL and close therapy monitoring, encouraging outcomes can be achieved even in resource-limited settings.

Effect of corticosteroid ointment on radiation induced dermatitis in head and neck cancer patients: A prospective study.

BACKGROUND: Almost all the patients receiving curative radiotherapy for head and neck cancer develop radiation dermatitis, which many a times leads to treatment interruption and reduce patient compliance. In this study, we evaluated the effect of potent topical steroid (Betamethasone Valerate 0.1%) cream on acute radiation dermatitis in head and neck cancer patients receiving curative radiotherapy. METHODS: A total 106 patients of head and neck cancers were randomly divided into arm A (52 patients) and arm B (54 patients). The patient in study arm A were treated with topical betamethasone 0.1% twice daily during radiotherapy/chemo-radiotherapy and arm B was kept as control. The radiation reaction in both the groups was monitored weekly according to Radiation Therapy Oncology Group (RTOG) acute radiation dermatitis grading. RESULTS: Out of 106 patients, 85 (80.2%) patients completed treatment. Patient in control arm had earlier onset of grade 1 reaction (5.7% in arm A vs 16.7 % in arm B at 2nd week, P value 0.157 and 28.8% in arm A vs 50% in arm B at 3rd week, P value 0.028) and progression of radiation dermatitis. In 7th week patient in arm A had higher grade 1 reaction (17.3% in arm A vs 0% in arm B), while arm B had higher grade 2 reaction (66.7% arm B vs 55.8% in arm A). There was no difference in incidence of grade 3 and 4 reaction. No difference was observed in time taken for reaction to heal. CONCLUSION: Topical Betamethasone can delay the onset and progression of radiation dermatitis in head and neck cancer, without significant delay in wound healing.

Determination of Optimal Clinical Target Volume to Planning Target Volume Margins for Conformal Radiotherapy Planning using Image Guidance System in Rectal Cancer in Prone Position.

CONTEXT: In advanced radiotherapy techniques such as three-dimensional conformal radiotherapy (3DCRT) and intensity-modulated radiotherapy (IMRT), geometrical uncertainties are very crucial as they may lead to under dosing of tumor and over dosing of the nearby critical structures and hence, it is important to determine planning target volume (PTV) margins which are specific for every center. AIMS: The aim of this study is to determine adequate clinical target volume (CTV) to PTV margins specific to our radiotherapy center. SETTINGS AND DESIGN: To calculate CTV to PTV margins for rectal cancer patients in prone position using kV cone beam CBCT data sets. MATERIALS AND METHODS: With the Patient immobilized in prone position using thermoplastic mask, a CT simulation was done and a comprehensive 3DCRT plan was generated. Daily kV CBCT was done to check the patient setup error. Daily setup errors were recorded and evaluated retrospectively. RESULTS: CTV-PTV margin calculated for pelvis in the prone position was calculated using van Herk Formula and were found to be 0.5, 1.8, 0.7 cm in the lateral, longitudinal, and vertical directions, respectively. CONCLUSIONS: Image guidance is an effective method to evaluate patient setup errors. Good quality immobilization devices and stringent patient setup policies can help to reduce PTV margins further.

Epistaxis as the initial presentation in a case of rheumatic heart disease.

Rheumatic heart disease (RHD) remains prevalent in developing nations and shows varied presentations, causing diagnostic challenge. Here, we report a case of RHD in a 13-year-old boy who presented with recurrent epistaxis as the initial symptom. On detailed work-up, echocardiography revealed the incidental finding of involvement of mitral and aortic valves but the patient never had any symptom as per the diagnostic criteria for RHD. This report highlights the clinical and epidemiological significance of atypical presentations as such cases might go undiagnosed and untreated, seeking medical attention in advanced stages, which would have otherwise contributed to the actual prevalence of the disease in the population.
