Barriers to Community-Based Eradication of Helicobacter pylori Infection.

Helicobacter pylori (HP) is a causative agent in gastric cancer (GC).1 In the United States, HP is more prevalent in racial and ethnic minorities, including African Americans, Asian Americans, Latinos, and immigrants, the same groups that are more likely to develop and die from GC.2 Although screening for HP is not presently performed in the United States, there are plausible benefits to doing so, because HP is considered a group 1 carcinogen by the World Health Organization, and its link to GC parallels that of human papilloma virus and cervical cancer.1 HP eradication as a means of preventing GC also fulfils the Wilson and Jungner criteria for a successful screening program, and literature has consistently demonstrated that HP eradication reduces GC risk and death from GC.3 In fact, in countries with a high burden of GC, HP eradication is considered primary prevention for GC. As such, targeted HP testing in the United States may reduce GC burden in high-risk groups.4 We evaluate the results of community-based HP testing in an at-risk, underserved population.

iTBS to Relieve Depression and Executive Dysfunction in Older Adults: An Open Label Study.

BACKGROUND: Executive Function Deficits (EFD) accompany depression and are associated with poor outcomes in older adults. We examined whether Intermittent Theta Burst Stimulation (iTBS) could improve depression with EFD. METHODS: Thirteen geriatric patients with depression and EFD were enrolled. Open label iTBS was delivered bilaterally over the dorso-lateral-prefrontal-cortex for four weeks. RESULTS: Montgomery Asberg Depression Scale scores improved significantly from baseline to treatment-end, mean change in score = 11.82 points, 95% CI = 8.3, 15.4. The Flanker Inhibitory control and attention test showed significant improvement in executive function from baseline to treatment-end, mean change in score = -7.73, 95% CI ( -13.54, -1.92). Side effects included twitching in facial muscles (n = 11), headaches (n = 10) and stimulation discomfort (n = 4). LIMITATIONS: Small sample size and lack of a sham comparator. CONCLUSION: iTBS improved depression with EFD in older adults. Side effects appeared higher than in previous iTBS studies.
