RESUMEN
OBJECTIVE: The coronavirus-2019 (COVID-19) pandemic caused delaying breast cancer management, increasing time interval in chemotherapy cycles and surgery. This has implications on radiological manifestation of cancer. Further, we evaluated changes observed in mammography. MATERIALS AND METHODS: This case control study was conducted from March 25th, 2020 to August 15th, 2020 at the Integrated Breast Care Centre, All India Institute of Medical Science Rishikesh (AIIMS), Rishikesh. Sonomammography was performed on follow-up patients who were on chemotherapy and were scheduled for surgery. Moreover, duration of delay from the last neoadjuvant chemotherapy (NACT) cycle was recorded. Similar data in the pre-COVID-19 period from November 4th, 2019 to March 24th, 2020 was compared with post-COVID-19 data and was analyzed by SPSS Version 23. RESULTS: The study included 54 patients who presented between March 25th, 2020 and August 15th, 2020. Furthermore, the delay in NACT cycles has been shown to be associated with disease progression (p = 0.045). Subgroup analysis of treatment duration with various parameters revealed significant correlation between size, appearance of ulceration, and response evaluation (p<0.05). However, no significant association was found between duration of delay and the histological subtype of lesion (p>0.05). A substantial difference was seen in the evaluation of NACT response in pre- and post-COVID-19 time, with partial response (n = 39, 58.24%) seen as the most common response in pre-COVID-19 time and progressive disease (n = 28, 51.9%) as the most common response in post-COVID-19 time (p<0.001). CONCLUSION: The coronavirus pandemic has severe impact on breast cancer management. A delay in NACT causes progression in cancer. This can be seen in ultrasound and mammogram.
RESUMEN
AIMS AND OBJECTIVES: To prospectively evaluate the impact of cardiopulmonary ultrasound (CPUS) on etiological diagnosis and treatment of critically ill acute respiratory failure (ARF) patients. DESIGN: This is a prospective observational study conducted in a general intensive care unit (ICU) of a tertiary care center in India. Patients over 18 years old with presence of one of the objective criteria of ARF. Patients either consecutively admitted for ARF to ICU or already admitted to ICU for a different reason but later developed ARF during their hospital stay. Written informed consent in local language was obtained from next of kin. INTERVENTIONS: All included patients underwent bedside CPUS including lung ultrasound (US) and transthoracic echocardiography plus targeted venous US by single investigator, blinded to clinical data. The US diagnosis of ARF etiology was shared with treating intensivist. Initial clinical diagnosis (ICD) and treatment plan (made before US) of each patient were compared with post-US clinical diagnosis and treatment plan. The changes in diagnosis and treatment up to 24 hours post-US were considered as impact of US. RESULTS: Mean age of 108 included patients was 45.7 ± 20.4 years (standard deviation). The ICD was correct in 67.5% (73/108) cases, whereas the combined CPUS yielded correct etiological diagnosis in 88% (95/108) cases. Among the 108 included patients, etiological diagnosis of ARF was altered after CPUS in 40 (37%) patients, which included "diagnosis changed" in 18 (17%) and "diagnosis added" in 22 (20%). Treatment plan was changed in 39 (36%) patients after CPUS, which included surgical interventions in 17 (16%), changes in medical therapy in 12 (11%), and changes in ventilation strategy in 4 (3.5%) patients. CONCLUSION: This study demonstrates that use of combined US approach as an initial test in ARF, improves diagnostic accuracy for identification of underlying etiology, and frequently changes clinical diagnosis and/or treatment.
