Direct-to-consumer genetic tests for heart disease

Direct-to-consumer genetic tests can screen for rare heart conditions that arise from variants in a single gene (such as cardiomyopathies) as well as common conditions influenced by many thousands of gene variants (such as coronary artery disease).

The dangerous dismissal of women’s pain

Studies show that women’s pain experiences are often minimized, dismissed, or undertreated by clinicians. Women and men perceive pain differently. Factors contributing to women’s undertreatment for pain include lack of objective pain measures, uncertain diagnoses, clinician bias, and how women are socialized. Women can ensure their pain is taken seriously by communicating closely with clinicians about expectations, stating they recognize their pain may not be 100% relieved, and doing their own research on possible reasons for pain.

A hair-pulling disorder

Trichotillomania is a mental health disorder characterized by frequent, irresistible impulses to pull hair from the scalp or anywhere else on the body. It often results in embarrassing bald patches that people with the condition try to conceal. About one in 50 people has trichotillomania, and women are diagnosed and treated for it more often than men are. People with the disorder may pull hair when faced with stressors such as tension, loneliness, or fatigue. Among people who eat pulled hair, complications such as hairballs can be life-threatening.

Kidney stones: From agony to action

Kidney stones are increasingly common among Americans. Made of minerals and acid salts in the urine, the hard deposits cause symptoms when they get stuck in the ureter, the tube that leads to the bladder. Symptoms include excruciating pain, blood in the urine, nausea, vomiting, fever, and chills. Risk factors for kidney stones include low fluid intake, family history, pregnancy, obesity, high blood pressure, gastric bypass surgery, and eating foods high in salt or sugar. Most kidney stones pass on their own, but treatments can retrieve or destroy the stones.
