Rheumatoid arthritis (RA) affects two to three times as many women as men. Scientists are uncovering RA's potential genetic and hormonal underpinnings, which point to potential reasons why women are more vulnerable. The newest treatments, called Janus kinase (JAK) inhibitors, resulted from research that has teased out delicate differences in immune system pathways. They block numerous proteins that ramp up inflammation fundamental to RA. The wide array of drug options now available for RA help doctors personalize therapies to each patient.

People may choke on their own saliva when talking quickly, laughing, or turning their head. Other causes include postnasal drip or dry mouth, which medications may trigger. Certain health conditions can also affect swallowing.

Generalized itching is common and has many potential causes. Examples include skin changes that occur with age; skin conditions; and many other diseases such as diabetes, thyroid disease, kidney disease, and liver disease. Relief involves treating underlying conditions; using medications that ease itching; bathing with lukewarm rather than hot water; using soap only on the armpits, genitals, feet, and face; and moisturizing immediately after showering or bathing.

Carpal tunnel syndrome is caused by increased pressure within the carpal tunnel, a narrow passage in the wrist containing the median nerve and tendons that run into the hand. The condition can lead to persistent tingling and numbness in the hands.

Doctors are rethinking their recommendations about a supplement used to help slow dry age-related macular degeneration (AMD). They're advising people to keep taking the pill even when they reach the late stage of the disease. Previously, the supplement-a cocktail of antioxidant nutrients known as the AREDS2 formula-was believed to slow disease progression only in the beginning and intermediate stages of dry AMD. New evidence suggests the supplement might also slow vision loss in late-stage dry AMD.
