To describe the impact of the coronavirus disease 2019 (COVID-19) pandemic on the characteristics of retinal detachments (RD) at a tertiary centre.

Retrospective consecutive case series.

One hundred and ninety eyes of 188 patients with primary, rhegmatogenous RD.

Patients with RD who presented over a 1-year period (September 14, 2019 to September 13, 2020). The relationship between demographic, anatomic, and visual acuity parameters were compared before and after onset of the pandemic using generalized estimating equations.

Macular status and corrected distance visual acuity on presentation.

One hundred and eighty-seven eyes, divided into 2 cohorts pre-COVID (n = 100 September 14, 2019 to March 13, 2020) and post-COVID (n = 87, March 14, 2020 to September 13, 2020). Of the eyes, 63.2% (n = 87) presented with macular detachment in the post-COVID group compared with 45% (n = 100) in the pre-COVID group (odds ration [OR], 2.14; 95% confidence interval [CI],1.19-3.86; p = 0.011). As well, eyes in the presentation with respect to macular detachment, extent of RD, and presenting visual acuity. At final follow-up, final visual acuity and anatomic outcomes were similar between the 2 groups. These data are helpful for future patient education, triaging, and treatment decision making.

The COVID-19 pandemic has adversely affected population mental health. We aimed to assess temporal trends in primary care-recorded common mental illness, episodes of self-harm, psychotropic medication prescribing, and general practitioner (GP) referrals to mental health services during the COVID-19 emergency in the UK.

We did a population-based cohort study using primary care electronic health records from general practices registered on the UK Clinical Practice Research Datalink (CPRD). We included patient records from Jan 1, 2010, to Sept 10, 2020, to establish long-term trends and patterns of seasonality, but focused primarily on the period January, 2019-September, 2020. We extracted data on clinical codes entered into patient records to estimate the incidence of depression and anxiety disorders, self-harm, prescriptions for antidepressants and benzodiazepines, and GP referrals to mental health services, and assessed event rates of all psychotropic prescriptions and self-harm. We used mean-dispersion nindividuals aged younger than 45 years. By September, 2020, rates of incident depression, anxiety disorder, and self-harm were similar to expected levels. In Northern Ireland, Scotland, and Wales, rates of incident depression and anxiety disorder remained around a third lower than expected to September, 2020. In April, 2020, the rate of referral to mental health services was less than a quarter of the expected rate for the time of year (75·3% reduction [74·0-76·4]).

Consequences of the considerable reductions in primary care-recorded mental illness and self-harm could include more patients subsequently presenting with greater severity of mental illness and increasing incidence of non-fatal self-harm and suicide. Addressing the effects of future lockdowns and longer-term impacts of economic instability on mental health should be prioritised.

Women are not routinely tested for oropharyngeal Neisseria gonorrhoeae. At present, selective testing based on sexual behaviour or risk groups is advocated by international guidelines. Many oropharyngeal infections are asymptomatic and thus remain undetected, establishing a reservoir for ongoing transmission. Data on effectiveness of routine testing are scarce, thus we aimed to assess the optimal testing strategy for oropharyngeal N gonorrhoeae in women.

In this retrospective cohort study, we used surveillance data obtained from all sexually transmitted infection (STI) clinics in the Netherlands between Jan 1, 2008, and Dec 31, 2017. selleck chemicals llc We collected consultation-level data, and individual-level patient data from 2016 onwards, on sociodemographic characteristics, sexual behaviour in the past 6 months, self-reported symptoms, and STI diagnoses. We compared the prevalence of oropharyngeal N gonorrhoeae between women who attended clinics that offered routine universal testing (defined as >85% of women tested isses more than two-thirds of oropharyngeal N gonorrhoeae infections in women, of whom half have oropharyngeal infections without concurrent genital or anorectal infections. Using independent risk factors for oropharyngeal infection to guide testing is a minimal testing strategy. Routine universal testing is the optimum scenario to detect the majority of infections. However, future studies are needed to assess the cost-effectiveness of routine testing and its effect on antimicrobial resistance.

In a recent Science issue, Guo et al. demonstrated that the gut microbiota-and its associated metabolites-play a central role in protecting against high-dose radiation.Microbes expertly manipulate hosts to their advantage, but few completely escape detection. In this issue of Cell Host & Microbe, Takaki et al.

Virus evolution is here to help. Through detailed studies of poliovirus vaccine reversion to virulence, Valesano and colleagues remind us that some things in life can, indeed, be counted on.More than 390 million human dengue virus (DENV) infections occur each year, worldwide. Dengvaxia, a live-virus tetravalent vaccine from Sanofi Pasteur, was recently approved for human clinical use, although vaccine performance against the four DENV serotypes is highly variable. Other dengue vaccines in advanced clinical testing also demonstrate variability in efficacy. In this review, we outline the benefits and challenges of developing a safe, effective, and balanced DENV vaccine that can provide uniform protection against all four serotypes. Even though T cell biology plays an important role in establishing protective immunity, this review focuses on B cell responses. We discuss the leading dengue vaccine candidates and review the specificity of antibody responses and the known immune correlates of protection against DENV infection. A better understanding of immune correlates of protection against DENV infection will inform the development of a vaccine that can provide long-term, uniform protection.
