Background  The orbit is an anatomically complex structure comprising the globe, extraocular muscles, fat, vascular, nervous, glandular, and connective tissues. Tetrahydropiperine A wide variety of neoplasms can arise from different orbital structures, which can create a diagnostic challenge to the pathologists. No formal study has been conducted in this regard in North East India. Aim and Objectives  This article aims to document the pattern and prevalence of orbital tumors in our institute and assess the utility of histopathological examination (HPE) and immunohistochemistry (IHC) in the precise diagnosis of these neoplasms. Materials and Methods  A retrospective analysis of orbital tumors was performed over a period of 5 years from 2013 to 2018 in the department of pathology at a tertiary cancer center of North East India following all the guidelines of the institutional ethics committee. Results  A total of 35 cases of orbital neoplasms, evaluated by HPE and IHC, were found, all of them being malignant tumors. The age range ones were crucial in the precise diagnosis of the neoplasms encountered. Conclusion  A variety of malignant orbital tumors may be seen in clinical practice. Management of these tumors requires a multidisciplinary approach. HPE in conjunction with IHC evaluation is of utmost importance in the veracious recognition of orbital tumors for their proper management.Background  Endometrial carcinoma is often preceded by characteristic histopathologic lesions known as endometrial hyperplasia. Estrogen, p53, PTEN, and overexpression of cyclin D1 appear to be involved in the development of endometrial carcinogenesis. Design  We evaluated and compared the expression profile of cyclin D1 expressions in 50 endometrial samples submitted as either endometrial curetting ( n = 34) or hysterectomy ( n = 16) specimens, which were diagnosed as simple hyperplasia ( n = 10), complex hyperplasia ( n = 06), atypical hyperplasia ( n = 04), and endometrial carcinoma ( n = 20). Ten cases of normal proliferative and secretory endometrium were selected as controls. Breast cancer with known cyclin D1 expression was selected as a positive control in each immunohistochemistry run. Results  Cyclin D1 was significantly overexpressed in glands with complex hyperplasia and endometrial adenocarcinoma compared with proliferative or secretory endometrium and simple hyperplasia. A statistical difference was found in the extent of cyclin D1 positivity of simple hyperplasia and carcinoma of the endometrium ( p less then 0.005). No statistical difference was seen between complex hyperplasia and carcinoma and clinicopathologic parameters in endometrioid carcinomas. All cases of clear cell carcinoma and serous carcinoma showed cyclin D1 immunoreactivity. Significant statistical difference was seen between cyclin D1 expression and only one clinicopathologic parameter, i.e., menopausal status in endometrial carcinomas Conclusion  Cyclin D1 over expression may be an early event in endometrial carcinogenesis and cyclin D1 over expression may be an informative biomarker to recognize subsets of endometrial lesions that may be precancerous and therefore amenable to surgical therapy.
To rank clinician-driven tests and treatments (CTTs) by their total cost during the birth hospitalization for preterm infants.

Retrospective cohort of very low birth weight (<1500 g) and/or very preterm (<32 weeks) subjects admitted to US children's hospital Neonatal Intensive Care Units (2012-2018). CTTs were defined as pharmaceutical, laboratory and imaging services and ranked by total cost.

24,099 infants from 51 hospitals were included. Parenteral nutrition ($85M, 32% of pharmacy costs), blood gas analysis ($34M, 29% of laboratory costs), and chest radiographs ($18M, 31% of imaging costs) were the costliest CTTs overall. More than half of CTT-related costs occurred during 10% of hospital days.

The majority of CTT-related costs were from commonly used tests and treatments. Targeted efforts to improve value in neonatal care may benefit most from focusing on reducing unnecessary utilization of common tests and treatments, rather than infrequently used ones.

One-week clinical and radiological findings were consistent with tumor progression. Positron emission tomography-computed tomography (PET-CT) at 1 month post CAR T cells administration was consistent with treatment response. The rapid tumor growth and subsequent resolution are suggestive of tumor pseudo-progression mediated secondary to infiltration and immune activation of CAR T cells. Overall, 56 adult patients with NHL were enrolled in a phase 1b/2 in house clinical study with CD19 CAR T cells. Out of them 22/56 patients progressed as per PET-CT the 1 month post CAR T cells. In 14 patients, signs of progression started 7-10 days after CAR T cells infusion. In 11/14 patients, it was true progression, while in 3 it was pseudo-progression. Additional studies are warranted to describe the extent of this phenomenon and evaluate correlation with the CAR T activity and long-term disease control.Posttransplant relapse represents the greatest obstacle to the success of allogeneic hematopoietic cell transplantation (HCT) for patients with acute myeloid leukemia (AML). This study investigated clinical features and outcomes of posttransplant relapse of AML based on data for 1265 patients with AML suffering relapse after allogeneic HCT conducted during complete remission (CR). Relapse occurred at a median of 6.1 months. The incidence rate of relapse peaked at 29.0 per 100 patient-years during the first 3-6 months period post transplant, after which the rate declined over time, and after 3 years remained consistently at less than 1 per 100 patient-years. The probability of overall survival (OS) after posttransplant relapse was 19% at 2 years, with 68% of deaths being attributed to leukemia. The interval from transplantation to relapse was identified as the strongest indicator for OS. Donor lymphocyte infusion (DLI) and second allogeneic HCT (HCT2) were administered to 152 (12%) and 481 (38%) patients, respectively.
