A recent study published in JAMA found that the steroid Prednisone proved effective in stabilizing and improving hearing in patients with AIED (autoimmune ear disorder) but failed to maintain these gains over time. The study also tested Methotrexate, a promising anti-inflammatory drug, which showed no significant benefit in treating AIED.

A study found that bupropion significantly reduced withdrawal symptoms and increased abstention rates from smoking. The medication also decreased negative mood in participants, which was more strongly related to relapse.
Postmenopausal women taking glucocorticoids are at a significantly increased risk of spinal fractures, with nearly six-fold higher odds compared to those not using the medication. Long-term use for chronic diseases can lead to glucocorticoid-induced osteoporosis (GIO), which increases the risk of fracture.
A randomized, double-blind trial found that magnesium supplementation had no effect on 30-day mortality in patients with acute STEMI. The study's results support current coronary care practice and suggest that routine administration of intravenous magnesium is not indicated.

A recent study found that patients undergoing arthroscopic lavage or debridement for osteoarthritis of the knee did not experience greater pain relief or improved function compared to those receiving placebo surgery. The researchers suggest that the same therapeutic benefits may be achieved through non-invasive treatment methods.
Researchers conducted two studies on venlafaxine XR, a SNRI medication, for social anxiety disorder (SAD) treatment. The results showed significant reductions in SAD symptoms as early as four or six weeks after treatment began, with continued improvements through week 12.

A study of 355 patients with severe Crohn's disease found that infliximab treatment every two months significantly increased remission rates compared to placebo. Infliximab also allowed patients to taper off steroids and maintain clinical remissions.
A multi-center research team found that infliximab prolonged remissions in moderate to severe Crohn's disease patients by twice as long at bi-monthly infusions compared to every eight weeks. The drug also helped patients reduce steroid use and improve quality of life.
A team of researchers found that both placebo and antidepressant responders showed increased activity in the cortex, accompanied by decreased activity in limbic regions. Patients who responded to fluoxetine also experienced unique changes in lower brain areas thought to confer additional advantage in sustaining the response.
A study found that depressed patients who responded to a placebo treatment showed similar brain changes as those who received an antidepressant, but with additional changes in the brainstem and hippocampus. The researchers suggest that these changes may be necessary for long-term recovery.
A double-blind clinical trial of 55 Lyme disease patients with severe fatigue revealed that while ceftriaxone showed promise in reducing fatigue, it was not without significant adverse effects. The study's results do not support the use of repeated courses of ceftriaxone due to these risks.
