Estudo associa medicamentos comuns para SII a maior risco de morte a longo prazo

Pesquisadores do Cedars-Sinai analisaram quase 20 anos de registros de saúde de mais de 650.000 adultos americanos com síndrome do intestino irritável, encontrando associações entre certos medicamentos e o aumento da mortalidade. Antidepressivos foram relacionados a um risco de morte 35% maior, enquanto a loperamida e o difenoxilato mostraram um risco cerca de duas vezes maior em comparação aos não usuários. Outros tratamentos para a SII, como medicamentos aprovados pela FDA e antiespasmódicos, não apresentaram tal aumento.

O estudo, publicado na Communications Medicine, examinou a segurança a longo prazo dos tratamentos para a SII, uma condição crônica que afeta cerca de 10% dos americanos. Liderada por Ali Rezaie, MD, diretor médico do Programa de Motilidade Gastrointestinal do Cedars-Sinai, a pesquisa preencheu uma lacuna deixada por ensaios clínicos de curta duração, que normalmente duram menos de um ano, apesar de os pacientes frequentemente usarem medicamentos por décadas. Rezaie observou: 'Muitos pacientes são diagnosticados com SII em uma idade jovem e podem permanecer sob medicação por anos.'

A small study of adults undergoing screening colonoscopy found that people who reported using smartphones while sitting on the toilet were more likely to have hemorrhoids detected during the procedure. The research, published in PLOS One, also found phone users spent longer on the toilet than non-users, though the authors cautioned the results show an association rather than proof that phones cause the condition.

A new genetic analysis has identified key DNA regions influencing how often people have bowel movements, with a surprising link to vitamin B1. Researchers analyzed data from over 268,000 individuals and found that higher thiamine intake correlates with more frequent stools, depending on genetic variations. The findings, published in Gut, suggest new pathways for studying gut disorders like irritable bowel syndrome.

A study of over 375,000 Finns has linked hospital treatment for severe infections like cystitis and pneumonia to a higher risk of developing dementia within five to six years. Researchers identified 29 conditions associated with at least a 20 percent increased risk, with infections playing a key role. The findings suggest that preventing such infections could help modify dementia risk.
