RESUMO
OBJECTIVES: To evaluate the clinical, fiscal and environmental impact of a specialist-led acute ureteric colic virtual clinic (VC) pathway. PATIENTS AND METHODS: All patients with uncomplicated acute ureteric colic, referred to a single tertiary centre, were prospectively entered into the study over a 4-year period (January 2015-December 2018). Inclusion criteria were: low-dose non-contrast computed tomography of kidneys, ureters and bladder; white blood cell count <16 × 109/L; pain controlled; normal renal function; and no clinical concern. Primary outcomes were: time (days) from referral to VC outcome; VC outcome (discharge, further VC, face-to-face [FTF] clinic, extracorporeal shockwave lithotripsy [ESWL], ureterorenoscopy [URS], percutaneous nephrolithotomy [PCNL]); and adverse events (sepsis or obstruction). Secondary outcomes were patient and stone demographics, cost and environmental analysis. The minimum follow-up was 3 months. RESULTS: A total of 1008 patients entered the study, of whom 91.5% (n = 922) were of working age. The median (interquartile range) time from presentation to VC outcome was 2 (4) days. VC outcomes were as follows: 16.3% of patients (n = 164) were discharged; 18.2% (n = 183) were discharged after further VC; 17.2% (n = 173) underwent an intervention; and 48.4% (n = 488) were referred to an FTF clinic. Interventions comprised: PCNL 0.5% (n = 5); ESWL 7.7% (n = 78); and URS 8.9% (n = 90). Stone demographics were as follows: 570 patients (56.5%) had lower, 157 (15.6%) had upper, 96 (9.5%) had mid-ureteric and 163 (16.2%) had renal calculi, and in 22 patients (2.2%) the stones had recently passed. The mean (sd) stone size was 3.5 (2.3) mm. Two adverse events (0.2%) were reported. Introducing a VC saved £145,152 for Clinical Commissioning Groups, the equivalent NHS tariff payment of performing 106 URS procedures or 211 ureteric stent insertions. Overall, 15,085 patient journey kilometres were avoided, equal to 0.70-2.93 metric tonnes of carbon dioxide equivalent production and the need to plant 14.7 trees to achieve carbon balance. CONCLUSION: A specialist-led acute ureteric colic VC reduced time to treatment decision to a median of 2 days. This creates additional clinic capacity and reduces the fiscal burden of traditional clinics and their associated carbon footprint.

Background: Rezum water vapour ablation is an effective minimally invasive surgical therapy for the treatment of bladder outflow obstruction. Objective: To present early outcomes and reoperation rates after Rezum, including an analysis of retreatment rates to gain an insight into optimal patient selection and the durability of the procedure. Design setting and participants: Data were prospectively collected for consecutive patients undergoing Rezum for symptomatic benign prostatic hyperplasia between March 2017 and January 2020 at two hospital sites. Intervention: Rezum treatment of the prostate. Outcome measurements and statistical analysis: Patients were reviewed at 6 wk and 3, 6, and 12 mo after their Rezum procedure. We evaluated changes in urinary symptoms and the retreatment rate. Results and limitations: A total of 461 patients undergoing Rezum were analysed. The mean (±standard deviation) follow-up duration was 16.7 ± 10.4 mo. The mean patient age was 67.5 ± 7.8 yr and the mean prostate volume was 56.5 ± 24.0 ml. There was a significant improvement in mean maximum flow rate and postvoid residual volume and in International Prostate Symptom Score and quality-of-life scores (p < 0.0001). During the follow-up period, 21 patients (4.6%) required retreatment, of which 11 cases (2.4%) were within the first year. The retreatments included eight bladder neck incisions or resections, six transurethral resections of the prostate, four Greenlight laser photoselective vaporisations of the prostate, and three Rezum procedures. The median length of time to a further operation was 11.5 mo (range 3-34). The most common findings at reoperation were an inadequately treated median lobe, an obstructing bladder neck, and in some cases asymmetry of the prostate cavity or recesses within the prostate gland. Conclusions: This study demonstrates that the beneficial effects of Rezum observed in the pivotal phase 2 randomised study are transferable to a real-world population with a comparable early retreatment rate. A range of procedures were used for retreatment. The factors dictating which option to select were based on patient concerns regarding side effects, gland volume, symptom profile, and cystoscopy findings. Patient summary: We investigated outcomes for patients undergoing Rezum, a water vapour treatment to reduce the size of the prostate in men with obstruction of the bladder outlet because of benign prostate enlargement. This technique yields significant improvements in symptoms and preserves sexual function. The proportion of men needing retreatment was 2.4% in the first year after their Rezum procedure.
RESUMO
BACKGROUND: Gathering and evaluating information leads to better decisions, but often at cost. The balance between information seeking and exploitation features in neurodevelopmental, mood, psychotic and substance-related disorders. Serotonin's role has been highlighted by experimental reduction of its precursor, tryptophan. AIMS: We tested the boundaries and applicability of this role by asking whether changes to information sampling would be observed following acute doses of serotonergic and catecholaminergic clinical treatments. We used a variant of the Information Sampling Task (IST) to measure how much information a person requires before they make a decision. This task allows participants to sample information until satisfied to make a choice. METHODS: In separate double-blind placebo-controlled experiments, we tested 27 healthy participants on/off 20 mg of the serotonin reuptake inhibitor (SRI) citalopram, and 22 participants on/off 40 mg of the noradrenergic reuptake inhibitor atomoxetine. The IST variant minimised effects of temporal impulsivity and loss aversion. Analyses used a variety of participant prior expectations of sampling spaces in the IST, including a new prior that accounts for learning of likely states across trials. We analysed behaviour by a new method that also accounts for baseline individual differences of risk preference. RESULTS: Baseline preferences demonstrated risk aversion. Citalopram decreased the expected utility of choices and probability of being correct based on informational content of samples collected, suggesting participants collected less useful information before making a choice. Atomoxetine did not influence information seeking. CONCLUSION: Acute changes of serotonin activity by way of a single SRI dose alter information-seeking behaviour.

BACKGROUND: On March 11, 2020, the World Health Organization declared SARS-CoV-2, causing COVID-19, as a pandemic. The UK mass vaccination program commenced on December 8, 2020, vaccinating groups of the population deemed to be most vulnerable to severe COVID-19 infection. OBJECTIVE: This study aims to assess the early vaccine administration coverage and outcome data across an integrated care system in North West London, leveraging a unique population-level care data set. Vaccine effectiveness of a single dose of the Oxford/AstraZeneca and Pfizer/BioNTech vaccines were compared. METHODS: A retrospective cohort study identified 2,183,939 individuals eligible for COVID-19 vaccination between December 8, 2020, and February 24, 2021, within a primary, secondary, and community care integrated care data set. These data were used to assess vaccination hesitancy across ethnicity, gender, and socioeconomic deprivation measures (Pearson product-moment correlations); investigate COVID-19 transmission related to vaccination hubs; and assess the early effectiveness of COVID-19 vaccination (after a single dose) using time-to-event analyses with multivariable Cox regression analysis to investigate if vaccination independently predicted positive SARS-CoV-2 in those vaccinated compared to those unvaccinated. RESULTS: In this study, 5.88% (24,332/413,919) of individuals declined and did not receive a vaccination. Black or Black British individuals had the highest rate of declining a vaccine at 16.14% (4337/26,870). There was a strong negative association between socioeconomic deprivation and rate of declining vaccination (r=-0.94; P=.002) with 13.5% (1980/14,571) of individuals declining vaccination in the most deprived areas compared to 0.98% (869/9609) in the least. In the first 6 days after vaccination, 344 of 389,587 (0.09%) individuals tested positive for SARS-CoV-2. The rate increased to 0.13% (525/389,243) between days 7 and 13, before then gradually falling week on week. At 28 days post vaccination, there was a 74% (hazard ratio 0.26, 95% CI 0.19-0.35) and 78% (hazard ratio 0.22, 95% CI 0.18-0.27) reduction in risk of testing positive for SARS-CoV-2 for individuals that received the Oxford/AstraZeneca and Pfizer/BioNTech vaccines, respectively, when compared with unvaccinated individuals. A very low proportion of hospital admissions were seen in vaccinated individuals who tested positive for SARS-CoV-2 (288/389,587, 0.07% of all patients vaccinated) providing evidence for vaccination effectiveness after a single dose. CONCLUSIONS: There was no definitive evidence to suggest COVID-19 was transmitted as a result of vaccination hubs during the vaccine administration rollout in North West London, and the risk of contracting COVID-19 or becoming hospitalized after vaccination has been demonstrated to be low in the vaccinated population. This study provides further evidence that a single dose of either the Pfizer/BioNTech vaccine or the Oxford/AstraZeneca vaccine is effective at reducing the risk of testing positive for COVID-19 up to 60 days across all age groups, ethnic groups, and risk categories in an urban UK population.
