Novel technique 'stuns' arthritis pain in shoulder and hip

A new outpatient procedure has been shown to provide significant pain relief for patients with moderate to severe osteoarthritis in their hip and shoulder joints. Treatment involves the placement of needles where sensory nerves exist, followed by a low-grade current that 'stuns' them, slowing pain transmission to the brain.

Chronic inflammation causes a reduction in NAD+

Researchers at the Buck Institute have identified chronic inflammation as a driver of NAD+ decline, a key metabolite central to an efficient and healthy metabolism. Senescent cells activate CD38, which degrades NAD+, leading to age-related diseases. Blocking CD38 activity may offer a new target for therapeutic interventions.

Study identifies patients with lung cancer most likely to respond to immunotherapy

Researchers found patients with a particular type of human leukocyte antigen (HLA) B44 were more likely to benefit from immunotherapy in melanoma but not non-small cell lung cancer. The study identified mutations driving the different responses, paving the way for better patient stratification and potential therapy design.

Randomized trial of laparoscopic, open liver surgery found no difference in long-term survival ou

A randomized controlled trial comparing laparoscopic and open liver surgery for patients with resectable colorectal liver metastases found no significant difference in 5-year survival outcomes. The study suggests that the laparoscopic approach may provide better short-term outcomes but does not jeopardize oncologic outcomes.

New drug can improve fertility in women with reproductive health problems

A new study finds that a drug called MVT-602 can improve fertility in women with reproductive health problems by targeting the kisspeptin hormone system. The drug's longer duration of action allows for less frequent dosing, offering improved treatment options for conditions such as polycystic ovary syndrome and hypothalamic amenorrhea.
