Article Synopsis
- The study examines the rising rates of early onset colorectal cancer (EOCRC) among African American patients, highlighting significant differences between EOCRC (<45 years) and late-onset colorectal cancer (LOCRC) (>45 years) in terms of demographics and clinical presentation.
- It found that EOCRC cases increased from just over 6% to over 13% of total CRC cases since 2010, with a higher family history of CRC and different symptom profiles, such as more abdominal pain and changes in bowel habits.
- The study also noted that EOCRC patients had a higher rate of metastasis at diagnosis and took longer to undergo surgery compared to LOCRC patients.

The UVI measurements used for the study were derived from the ultraviolet-B (UVB) irradiance measured by the Ozone Monitoring Instrument (OMI) of the AURA satellite and classified into different severity levels for analysis. Basic statistics of daily, monthly and seasonal UVI as well as Mann-Kendall (MK) statistical trend characteristics and the rate of change of daily UVI using Theil-Sen's slope test were also evaluated.

- Dengue fever, primarily transmitted by mosquitoes, has significantly impacted Kerala, especially in Thiruvananthapuram, prompting a study to identify risk zones using analytical methods like AHP and F-AHP.
- The study incorporates various geo-environmental and demographic factors, utilizing software tools like ArcGIS and ERDAS to create detailed risk zone maps, which are then validated against actual dengue case data.
- The results show that the F-AHP method outperforms AHP in predicting risk zones, with 82.87% of cases occurring in high-risk areas, highlighting the need for effective public health measures to combat dengue spread.
