The study found that such variations are not present at birth and for the first weeks of life, even as this is when mother-to-infant direct microbial transmission (through breastfeeding, for example) is strongest. Instead, the changes begin emerging at three months, suggesting external factors influence it. The childhood gut microbiome can affect the immune system and metabolic development later in life, so the factors that shape the microbiome early on could contribute to future ethnic and racial health disparities. Psychosocial stressors, socioeconomic status, environmental pollutants are all tied to health disparities, but further studies are necessary to identify which of these, if any, has an impact on gut microbiome development.

Having celiac disease and a thyroid condition sent her on a quest to become an empathetic doctor Isabella Cueto By Isabella Cueto Aug. 18, 2023

Having celiac disease and a thyroid condition sent her on a quest to become an empathetic doctor Isabella Cueto By Isabella Cueto Aug. 18, 2023 https://www.statnews.com/2023/08/18/celiac-hashimoto-thyroiditis-living-with-autoimmune-disease/?utm_campaign=morning_rounds&utm_medium=email&_hsmi=270760454&_hsenc=p2ANqtz-_v8q6c7kLaKY-2_tAl6Q6AaxubU7O2tpaZueiXLVu5UtlTVSPXLFLWMki2i31yLeYuX_u3o7XO4PHuLp6kJi7P_o8YtA&utm_content=270760453&utm_source=hs_email Third-year med school student Brianna Celix has the challenge of managing two autoimmune conditions: Hashimoto’s thyroiditis and celiac disease. She chatted with STAT’s Isabella Cueto about how her chronic conditions led her to study medicine and how she works with the dietary restrictions required of her celiac disease. How did your thyroid disease show up? And celiac? The first pediatric endocrinologist I met with essentially told me, “You’re an unhealthy, fat kid and you need to get it together.” It probably took about a month and a half for us to figure out what was really going on. How did these twin diagnoses affect your career choice? That’s my “why” for medicine. I usually disclose it right away: I’ve got this and I’ve got this, and I want to help folks with it and figure it out with them.

‘But I never smoked’: A growing share of lung cancer cases is turning up in an unexpected population Sharon Begley By Sharon Begley

‘But I never smoked’: A growing share of lung cancer cases is turning up in an unexpected population Sharon Begley By Sharon Begley https://www.statnews.com/2021/01/26/growing-share-of-lung-cancer-turning-up-in-never-smokers/?utm_campaign=morning_rounds&utm_medium=email&_hsmi=270760454&_hsenc=p2ANqtz-8pbybh8IgtNoG5WHi0zCRxEf2njxLA3sKSXtwDqQPWZiCYbdumNWHTEGUWK2V2bPMDwhPsuzyRgJL1N6eV6TpaVL1Zag&utm_content=270760453&utm_source=hs_email Screening rates for the deadliest cancer are low. Why? A 63-year-old Black man from Massachusetts, Michael Young never smoked, but he had almost all the other risk factors for lung cancer. He grew up on Air Force bases where the now-banned insecticide DDT was sprayed. Both his parents smoked, so he had 17 years of secondhand exposure. And in 2018, his mother was diagnosed with lung adenocarcinoma, the same type of cancer he eventually got. Despite all of this, neither was asked by their doctors to get screened. Their story reflects a lung cancer screening rate of just 5.7%, compared to 70% to 75% for other tests like mammograms, colonoscopies, and Pap smears. It’s been USPSTF-recommended only since 2013. Two reasons: insurance requirements and questions about who’s eligible, even as lung cancer has increased among never-smokers, as the late Sharon Begley reported in her last story. STAT’s Simar Bajaj has more on the issue.Screening rates for the deadliest cancer are low. Why?
