RESUMO

BACKGROUND: Historically, human monkeypox virus cases in the UK have been limited to imported infections from west Africa. Currently, the UK and several other countries are reporting a rapid increase in monkeypox cases among individuals attending sexual health clinics, with no apparent epidemiological links to endemic areas. We describe demographic and clinical characteristics of patients diagnosed with human monkeypox virus attending a sexual health centre. METHODS: In this observational analysis, we considered patients with confirmed monkeypox virus infection via PCR detection attending open-access sexual health clinics in London, UK, between May 14 and May 25, 2022. We report hospital admissions and concurrent sexually transmitted infection (STI) proportions, and describe our local response within the first 2 weeks of the outbreak. FINDINGS: Monkeypox virus infection was confirmed in 54 individuals, all identifying as men who have sex with men (MSM), with a median age of 41 years (IQR 34-45). 38 (70%) of 54 individuals were White, 26 (48%) were born in the UK, and 13 (24%) were living with HIV. 36 (67%) of 54 individuals reported fatigue or lethargy, 31 (57%) reported fever, and ten (18%) had no prodromal symptoms. All patients presented with skin lesions, of which 51 (94%) were anogenital. 37 (89%) of 54 individuals had skin lesions affecting more than one anatomical site and four (7%) had oropharyngeal lesions. 30 (55%) of 54 individuals had lymphadenopathy. One in four patients had a concurrent STI. Five (9%) of 54 individuals required admission to hospital, mainly due to pain or localised bacterial cellulitis requiring antibiotic intervention or analgesia. We recorded no fatal outcomes. INTERPRETATION: Autochthonous community monkeypox virus transmission is currently observed among MSM in the UK. We found a high proportion of concomitant STIs and frequent anogenital symptoms, suggesting transmissibility through local inoculation during close skin-to-skin or mucosal contact, during sexual activity. Additional resources are required to support sexual health and other specialist services in managing this condition. A review of the case definition and better understanding of viral transmission routes are needed to shape infection control policies, education and prevention strategies, and contact tracing. FUNDING: None.

RESUMO

Modafinil is a selective wakefulness-promoting agent with beneficial effects in narcolepsy and conditions of sleep deprivation. In a double-blind study we examined its effects in 30 healthy, non sleep-deprived students (19 men and 11 women, aged 19-23 years), who were randomly allocated to placebo, 100 or 200 mg modafinil and 3 h later completed 100 mm visual analogue scales relating to mood and bodily symptoms, before and after an extensive battery of cognitive tests (pen and paper and CANTAB). There were no significant differences between the three treatment groups on any of the cognitive tests used in this study. There was a significant post-treatment change in the factor measuring 'somatic anxiety' and in individual ratings of 'shaking', 'palpitations', 'dizziness', 'restlessness', 'muscular tension', 'physical tiredness' and 'irritability', which was mainly due to significantly higher ratings of somatic anxiety in the 100 mg group compared with the other two groups. Further changes in mood were revealed after the stress of cognitive testing, with the 100 mg group showing greater increases in the 'psychological anxiety' and the 'aggressive mood' factors (as measured from the Bond and Lader scales).
