Background: Surge of SARS CoV-2 infections ascribed to omicron variant began in December 2021 in New Delhi. We determined the infection and reinfection density in a cohort of health care workers (HCWs) along with vaccine effectiveness (VE) against symptomatic infection within omicron transmission period (considered from December 01, 2021 to February 25, 2022. Methods: This is an observational study from the All India Institute of Medical Sciences, New Delhi. Data were collected telephonically. Person-time at risk was counted from November 30, 2021 till date of infection/ reinfection, or date of interview. Comparison of clinical features and severity was done with previous pandemic periods. VE was estimated using test-negative case-control design [matched pairs (for age and sex)]. Vaccination status was compared and adjusted odds ratios (OR) were computed by conditional logistic regression. VE was estimated as (1-adjusted OR)X100-. Findings: 11474 HCWs participated in this study. The mean age was 36⋅2 (±10⋅7) years. Complete vaccination with two doses were reported by 9522 (83%) HCWs [8394 (88%) Covaxin and 1072 Covishield (11%)]. The incidence density of all infections and reinfection during the omicron transmission period was 34⋅8 [95% Confidence Interval (CI): 33⋅5-36⋅2] and 45⋅6 [95% CI: 42⋅9-48⋅5] per 10000 person days respectively. The infection was milder as compared to previous periods. VE was 52⋅5% (95% CI: 3⋅9-76⋅5, p = 0⋅036) for those who were tested within 14-60 days of receiving second dose and beyond this period (61-180 days), modest effect was observed. Interpretation: Almost one-fifth of HCWs were infected with SARS CoV-2 during omicron transmission period, with predominant mild spectrum of COVID-19 disease. Waning effects of vaccine protection were noted with increase in time intervals since vaccination. Funding: None.

INTRODUCTION: This trial was conducted to compare the efficacy of low dose once-a-week cisplatin and once-every-3-weeks cisplatin with radiation in locally advanced head and neck squamous cell carcinoma (LAHNSCC). The current analysis focuses on the quality of life (QoL) of patients in this trial. METHODS: In this phase III randomized trial, patients with nonmetastatic LAHNSCC were randomized to receive cisplatin 30 mg/m2 once-a-week or 100 mg/m2 once every- 3-weeks concurrently with radiotherapy. The primary endpoint was locoregional control. QoL was a key secondary endpoint. QoL was assessed using EORTC QLQ-C30 and QLQ-H&N35. QoL data were assessed at baseline, days 22 and 43 during treatment; and at 6, 12, 24 months. The linear mixed-effects model was used for longitudinal analysis of QoL to determine the impact of treatment (arm) and time on QoL. RESULTS: Three hundred patients were enrolled, data of 150 patients with available baseline QoL were analyzed. There was no significant difference in the global health status/QoL of the two treatment arms (p = 0.8664). There was no significant difference in the longitudinal QoL scores between the two treatment arms in all scales except constipation (p = 0.0096), less sexuality (p = 0.0002,), and financial difficulty (p = 0.0219). There was a worsening of the QoL scores in all scales in both arms during treatment, which improved after treatment completion in most scales. CONCLUSION: The use of once-every-3-weeks cisplatin did not adversely impact QoL as compared to once-a-week cisplatin in combination with radiotherapy in LAHNSCC.

PURPOSE: To understand the difficulties that happen during the quality of life (QoL) data collection in a pandemic and provide measures to overcome them. METHODS: We analyzed the recruitment and follow-up data of patients in one of our ongoing study whose aim was to collect the Adverse drug reactions and QoL (at regular intervals) in prostate cancer patients who were on docetaxel. Before the pandemic, we could enroll 31 patients in the study over four months. We analyzed the difficulties experienced by these patients and consultants in collecting QoL data during the pandemic, especially in situations with limited availability of resources and also where the patients are not technologically advanced. RESULTS: Due to the pandemic, we could not recruit a single new patient into the study. Complete QoL assessments were available in only two patients, and the disease progressed in five patients. QoL assessment was not possible in 19 of 31 enrolled patients. More than 44% of the enrolled patients had difficulty commuting to the hospital despite transport services to hospitals. Due to the risk of acquiring COVID19 infection during traveling to the hospital, follow-ups were affected. CONCLUSION: There should be increased support for novel technologies that can successfully capture and transfer patients' QoL data to the treating consultant.

Introduction TFE Translocation renal cell carcinoma (TRCC) represents 1 to 5% of all cases of renal cell carcinoma, with the highest frequency among children and young adults. Management of these tumors is not very well defined in literature. Although in pediatric age group it has favorable prognosis, in adults it has an aggressive nature, with poor outcome. This is a retrospective analysis of treatment outcome in adult patient 18 years or above treated at our hospital between January 2013 and November 2018. Material and Methods Clinical and pathological data of 26 patients from a single institution diagnosed with TRCC between January 2013 and November 2018 were retrospectively reviewed. All cases of TRCC were confirmed with immunohistochemistry or fluorescence in situ hybridization. We analyzed our data of patients treated with surgery only or who progressed after surgery and treated with systemic therapy or who presented with upfront unresectable or metastatic disease treated with systemic therapy with respect to event-free survival (EFS) and overall survival (OS). Results Between January 2013 and November 2018, 26 adult patients who were treated at our center were eligible for this analysis as per our criteria. Out of 26 patients, 25 patients had radical surgery after evaluation and 1 had metastatic disease who was started on systemic therapy. Out 25 patients who were treated with radical surgery, 16 patients progressed and they were started on systemic therapy except for 1 patient who defaulted. Median time to start systemic therapy among patient treated with curative nephrectomy was 13 months. Median EFS and median OS among overall population were 22 and 30 months, respectively. Among 16 patients who were treated with systemic therapy, median EFS to first-line therapy was 8 months and to second-line therapy was 2.5 months. Median OS was 17 months in patients treated with systemic therapy. Conclusion TRCC is rare in adult population but carries significant risk of disease progression even after initial curative treatment with potential response to targeted therapy for short duration.
