The hereditary persistence of fetal hemoglobin (HPFH) and delta beta thalassemia are heterogeneous disorders characterised by increased levels of fetal hemoglobin and high level of this Hb continues in adulthood. The distinction between these two conditions is not always possible with routine hematologic analysis and molecular characterisation of the defect is required. We encountered such a rare case of δ β thalassemia in a 10-year-old male child who presented with features of thalassemia intermedia. Hemoglobin analysis showed 100% HbF while molecular analysis revealed Asian Indian inversion-deletion GγAγ(δ β) zero thalassemia.

Introduction: Previous studies have reported an overall lower breast cancer incidence in women from Asian and Black backgrounds compared with white women. Age standardised and age specific incidence rates in the largest specific ethnicities within Asian and Black groups are not reported.
Materials And Methods: Data on population size and the age distribution of women in five ethnic groups of interest (white British, Black African, Black Caribbean, Indian and Pakistani) were extracted from the Office for National Statistics 2001, 2011 and 2021 census data for England.

Visible-light absorbing metal-free organic dyes are of increasing demand for various optoelectronic applications because of their great structure-function tunability through chemical means. Several dyes also show huge potential in triplet photosensitization, generating reactive singlet oxygen. Understanding the structure-property relationships of many well-known fluorescein dyes is of paramount importance in designing next-generation energy efficient dyes, which is currently limited.

Background: Medicare Bayesian Improved Surname and Geocoding (MBISG), which augments an imperfect race-and-ethnicity administrative variable to estimate probabilities that people would self-identify as being in each of 6 mutually exclusive racial-and-ethnic groups, performs very well for Asian American and Native Hawaiian/Pacific Islander (AA&NHPI), Black, Hispanic, and White race-and-ethnicity, somewhat less well for American Indian/Alaska Native (AI/AN), and much less well for Multiracial race-and-ethnicity.
Objectives: To assess whether temporal inconsistency of self-reported race-and-ethnicity might limit improvements in approaches like MBISG.
Methods: Using the Medicare Health Outcomes Survey (HOS) baseline (2013-2018) and 2-year follow-up data (2015-2020), we evaluate the consistency of self-reported race-and-ethnicity coded 2 ways: the 6 mutually exclusive MBISG categories and individual endorsements of each racial-and-ethnic group.
Temporal trends and patterns for early- and late-onset adult liver cancer incidence vary by race/ethnicity, subsite, and histologic type in the United States from 2000 to 2019.

Purpose: To examine incidence trends and patterns for early- and late-onset liver cancer.
Methods: Liver and intrahepatic bile duct (IBD) cancers diagnosed between 2000 and 2019 were acquired from 22 SEER registries. Variables included early-onset (20-49) vs.
