Introduction: The spectrum of haematological and non haematological disorders is vast in various age groups. Complete blood counts and other routine laboratory tests are not always sufficient to diagnose these diseases. Bone marrow examination plays an important role in diagnosing their underlying causes. Aim: To analyse the spectrum of various haematological and non haematological disorders reported in Bone Marrow Aspiration (BMA) and compare them with Bone Marrow Trephine Biopsy (BMB) and Flow Cytometry (FCM) findings where applicable. Materials and Methods: A one-year cross-sectional study was conducted in the Department of Clinical Pathology, PGIMS, Rohtak, Haryana, India from April 2022 to March 2023. A total of 518 consecutive BMA samples were morphologically analysed. Comparative evaluations were performed among BMA, BMB, and FCM where applicable. Diagnostic accuracy was calculated, and the findings of discordant cases were tabulated. Definitive diagnosis of lymphoma/leukaemia and Paroxysmal Nocturnal Haemoglobinuria (PNH) cases were made using FCM. Results: The patients' ages ranged from three months to 86 years, with a mean age of 38.4 years. The male to female ratio was 1.3:1, with a slight male predominance. The highest number of cases were of anaemia {183 (35.3%) and 164 (31.7%), respectively} and leukaemia {128 (24.7%) and 134 (25.9%), respectively}, followed by normal marrow studies {39 (7.5%) and 32 (6.2%), respectively} and megakaryocytic thrombocytopenia {24 (4.6% in each} in both BMA and biopsy. Among anaemia cases {183 and 164 cases in BMA and BMB}, the majority were of the megaloblastic type {62 (33.8%) and 54 (32.9%), respectively}, followed by hypoplastic/aplastic type {40 (21.8%) and 50 (30.5%), respectively}. In cases of leukaemia (128 and 134 cases in BMA and BMB), acute leukaemia cases (76 (59.4%) and 82 (61.2%), respectively} outnumbered chronic leukaemia cases {52 (40.6%) and 52 (38.8%), respectively} in both BMA and BMB. The concordance and discordance rate between BMA and BMB were 87.6% (419 cases) and 12.4% (59 cases), respectively. Diagnosis was exclusively made by BMB in cases of myelofibrosis, granulomatous disease, and Hodgkin's lymphoma. Conclusion: BMA cytology is a relatively safe and mildly invasive technique for evaluating various haematological and non haematological disorders with better preservation of cellular morphology. However, in cases with dry/blood taps and focal marrow involvement, BMB should be performed, as it shows well-preserved marrow architecture with all its cellular and stromal components. FCM is a definitive diagnostic modality for further categorisation of acute leukaemia and Chronic Lymphoproliferative Disorders (CLPD). [ABSTRACT FROM AUTHOR]

Background and Objectives: Coronavirus disease 2019 (COVID-19) caused several cardiovascular complications, including acute myocardial infarction (AMI), in infected patients. This study aims to understand the overall trends of AMI among COVID-19 patients during the first two years of the pandemic and the disparities and outcomes between the first and second years. Materials and Methods: The retrospective analysis was conducted via the 2020 and 2021 National Inpatient Sample (NIS) database for hospitalizations between April 2020 and December 2021 being analyzed for adults with a primary diagnosis of COVID-19 who experienced events of AMI. A comparison of month-to-month events of AMI and mortality of AMI patients with concomitant COVID-19 was made alongside their respective patient characteristics. Results: Out of 2,541,992 COVID-19 hospitalized patients, 3.55% experienced AMI. The highest rate of AMI was in December 2021 (4.35%). No statistical differences in trends of AMI mortality were noted over the 21 months. AMI cases in 2021 had higher odds of undergoing PCI (aOR 1.627, p < 0.01). They experienced higher risks of acute kidney injury (aOR 1.078, p < 0.01), acute ischemic stroke (aOR 1.215, p < 0.01), cardiac arrest (aOR 1.106, p < 0.01), need for mechanical ventilation (aOR 1.133, p < 0.01), and all-cause mortality (aOR 1.032, 95% CI 1.001–1.064, p = 0.043). Conclusions: The incidence of AMI among COVID-19 patients fluctuated over the 21 months of this study, with a peak in December 2021. COVID-19 patients reporting AMI in 2021 experienced higher overall odds of multiple complications, which could relate to the exhaustive burden of the pandemic in 2021 on healthcare, the changing impact of the virus variants, and the hesitancy of infected patients to seek care.

The article focuses on evaluating hospitalizations among patients with colorectal cancer in the U.S. between 2001 and 2020, particularly examining trends based on different colon cancer locations. It mentions Using ICD-9 and ICD-10 codes, the study found stable numbers for patients with cancer in the transverse and descending colon, a decrease in hospitalizations for ascending colon cancer until 2014 followed by a rise until 2019.

Introduction: Coronavirus disease 2019 (COVID-19) can lead to cardiovascular complications. We aimed to understand the trends in admission for COVID-19 and the incidence of various cardiovascular events., Material and Methods: The 2020 and 2021 National Inpatient Sample (NIS) was studied for cases of COVID-19 between April 2020 and December 2021 in the United States. Linear-by-linear association helped us understand the trends of various events., Results: The number of cases of COVID-19 was highest in January 2021 (261,469 patients). The incidence of acute pulmonary embolism rose from 2.08% in April 2020 to 4.82% in November 2021, while deep vein thrombosis cases rose from 1.74% in April 2020 to 2.63% in December 2021. The incidence of cardiac arrest varied, with a maximum of 3.00% in August 2021. Similarly, acute ischemic stroke cases experienced their highest incidence in January 2021 (0.91%). The incidence of myocarditis was highest in April and May 2020 (0.42% each). Peak takotsubo cases were seen between October and December 2021. The highest overall all-cause mortality among COVID-19 cases was seen in April 2020 (16.74%)., Conclusions: Throughout the 21 months of our analysis, various trends in COVID-19 cases and incidence of cardiac events were noticed. This could relate to the different variants of COVID-19, their direct and indirect impact on coagulation pathways and the myocardial tissues, and the protective roles of the vaccines., Competing Interests: The authors declare no conflict of interest., (Copyright: © 2024 Termedia & Banach.)
