Early sexual activity lowers the incidence of intracranial aneurysm: a Mendelian randomization investigation.

Objective: Investigate the potential correlation between the age of initial sexual contact, the lifetime accumulation of sexual partners, and the occurrence of intracranial aneurysm (IA) employing a two-sample Mendelian randomization approach.

Methods: This research aims to elucidate the causal relationship between intracranial aneurysm (IA) and sexual variables. Two distinct sexual variables, specifically the age had first sexual intercourse ( = 406,457) and the lifetime number of sexual partners ( = 378,882), were employed as representative parameters in a two-sample Mendelian randomization (MR) study.

Prescribing and using vitiligo treatments: lessons from a nested process evaluation within the HI-Light vitiligo randomized controlled trial.

Background: The HI-Light Trial demonstrated that for active, limited vitiligo, combination treatment with potent topical corticosteroid (TCS) and handheld narrowband ultraviolet B offers a better treatment response than potent TCS alone. However, it is unclear how to implement these findings.

Aim: We sought to answer three questions: (i) Can combination treatment be used safely and effectively by people with vitiligo?; (ii) Should combination treatment be made available as routine clinical care?; and (iii) Can combination treatment be integrated within current healthcare provision?

Methods: This was a mixed-methods process evaluation, including semi-structured interviews with a purposive sample of trial participants, structured interviews with commissioners, and an online survey and focus groups with trial staff.

Home-based narrowband UVB, topical corticosteroid or combination for children and adults with vitiligo: HI-Light Vitiligo three-arm RCT.

Background: Systematic reviews suggest that narrowband ultraviolet B light combined with treatments such as topical corticosteroids may be more effective than monotherapy for vitiligo.

Objective: To explore the clinical effectiveness and cost-effectiveness of topical corticosteroid monotherapy compared with (1) hand-held narrowband ultraviolet B light monotherapy and (2) hand-held narrowband ultraviolet B light/topical corticosteroid combination treatment for localised vitiligo.

Design: Pragmatic, three-arm, randomised controlled trial with 9 months of treatment and a 12-month follow-up.

Randomized controlled trial of topical corticosteroid and home-based narrowband ultraviolet B for active and limited vitiligo: results of the HI-Light Vitiligo Trial.

Background: Evidence for the effectiveness of vitiligo treatments is limited.

Objectives: To determine the effectiveness of (i) handheld narrowband UVB (NB-UVB) and (ii) a combination of potent topical corticosteroid (TCS) and NB-UVB, compared with TCS alone, for localized vitiligo.

Methods: A pragmatic, three-arm, placebo-controlled randomized controlled trial (9-month treatment, 12-month follow-up).
