Randomized Controlled Trial
Effect of Low-frequency repetitive transcranial magnetic stimulation as adjunctive treatment for insomnia patients under hypnotics: a randomized, double-blind, sham-controlled study.
Pharmacotherapy of insomnia is prescribed often but may be complicated by drug dependence. Cognitive-behavioral therapy for insomnia is effective, but requires time to take effect. Repetitive transcranial magnetic stimulation (rTMS) is effective for depression but of uncertain benefit for insomnia. We studied low-frequency rTMS of the left dorsal medial prefrontal cortex (DMPFC) as an adjunctive therapy of insomnia. ⋯ Although the effects of rTMS and sham coil on insomnia were similar (which implied significant placebo effect), low-frequency DMPFC-rTMS might offer a safe, non-invasive, and useful adjunctive therapy of insomnia by reducing WASO. The DMPFC may represent a new target for future rTMS insomnia studies.

Optic neuropathies were estimated to affect 115 in 100,000 population in 2018. Leber's Hereditary Optic Neuropathy (LHON) as one of such optic neuropathy diseases that was first identified in 1871 and can be defined as a hereditary mitochondrial disease. LHON is associated with three mtDNA point mutations which are G11778A, T14484, and G3460A that affect the NADH dehydrogenase subunits of 4, 6, and 1, respectively. ⋯ Aside from the mutations, there are several environmental factors such as smoking and alcohol consumption that can be pointed out as the risk factors of LHON. Nowadays, gene therapy has been intensively studied for LHON treatment. Disease models using human induced pluripotent stem cells (hiPSCs) have been utilized for LHON research.

To investigate the characteristics and clinical correlates of transient visual disturbances (TVDs) in patients with migraine without aura (MO). Patients with MO frequently report TVDs, which differ from typical visual aura, but the clinical significance of these TVDs has not been determined. ⋯ The presence of TVDs may imply greater migraine-related disability, photophobia, and suicidal ideation/suicide attempt risk in patients with MO.

Increasing evidence has suggested a strong association of Q223R (rs1137101) and K109R (rs1137100) polymorphisms in leptin receptor (LEPR) gene with susceptibility of breast cancer (BC), but inconsistent results were obtained. To provide a quantitative assessment of this association, a systematic review and meta-analysis was performed. ⋯ The available evidence suggests that Q223R polymorphism may be significantly associated with BC risk in African population. K109R polymorphism may be significantly associated with BC risk in Asian population.
