practice cases are more likely than nononcologic radiology cases to be due to diagnostic errors. Furthermore, compared with those that are nononcologic, oncologic radiology cases with diagnostic allegations are more likely to be associated with high-severity harm. Efforts are warranted to reduce misinterpretations of oncologic imaging.The anecdotal report describes two examples of COVID-19-positive healthcare professionals (HCPs) who had worked as nurses during pre-symptomatic period and subsequently presented a mild clinical course of COVID-19. The nurses' responsibilities were almost the same and worked in the general ward with no aerosol generating medical procedures. Two HCPs were expected to have similar infectiousness, but the number of secondary transmission by each HCP were different. Eleven close contacts from HCP1 were notified, and all of them tested negative for SARS-CoV-2. However, 13 of 35 close contacts of HCP2 tested positive for SARS-CoV-2. While working, mask-wearing style differed between the two HCPs. HCP1 wore a KF94 mask appropriately and kept wearing it while working. HCP2 wore a surgical mask while working, but often pulled it down to her chin or removed it. It was strongly suspected that the difference of mask wearing contributed to the SARS-CoV-2 transmission.  https://www.selleckchem.com/products/apr-246-prima-1met.html  However, other factors such as talkative behavior, exposure time, ventilation in rooms, and hand hygiene performance rates, could also have affected the transmission of COVID-19. It is crucial that healthcare workers wear a mask adequately and continuously, and they maintain proper hand hygiene while working during the COVID-19 pandemic.
  As a policy option to reduce consumption of alcohol and the harm it does, on May 1, 2018, Scotland introduced a minimum price of 50 British pence (p) per unit of alcohol (8 g) sold; Wales followed suit on March 2, 2020, with the same minimum unit price (MUP). We analysed household purchase data based on bar codes to assess the impact of these policy options in the medium term for Scotland and in the immediate term for Wales.
 
  For these location-controlled, interrupted time series regression analyses, the data source was Kantar WorldPanel's household shopping panel, which, at the time of our analysis, included 35 242 British households providing detailed information on 1·24 million separate alcohol purchases in 2015-18 and the first half of 2020. With no data exclusions, we analysed the impact of introducing MUP in Scotland, using purchases in northern England as control, and in Wales, using western England as control. The studied changes associated with MUP were price paid per gram of alcohol purchased, grl by households that generally bought small amounts of alcohol and, in particular, those with low incomes. The changes were not affected by the introduction of COVID-19 confinement in the UK on March 26, 2020.
 
  The evidence base supporting the positive, targeted impact of MUP is strengthened by the comparable results for Scotland and Wales. The short-term impact of MUP in Scotland during 2018 is maintained during the first half of 2020. MUP is an effective alcohol policy option to reduce off-trade purchases of alcohol and should be widely considered.

Here we present a key piece of this planning an up-to-date, fine-scale endemicity map and seasonality profile for Haiti informed by monthly case counts from 771 health facilities reporting from across the country throughout the 6-year period from January 2014 to December 2019. To this end, a novel hierarchical Bayesian modelling framework was developed in which a latent, pixel-level incidence surface with spatio-temporal innovations is linked to the observed case data via a flexible catchment sub-model designed to account for the absence of data on case household locations. These maps have focussed the delivery of indoor residual spraying and focal mass drug administration in the Grand'Anse Department in South-Western Haiti.
  During the first wave of the COVID-19 pandemic, University Hospitals Birmingham NHS Foundation trust was able to recommence elective orthopaedic surgery using private hospitals procured by the NHS as COVID-19 free 'green' sites. We report on the safety of elective orthopaedic surgery with high rates of community transmission.
 
  We conducted an observational cohort study on consecutive NHS patients attending three private hospitals between 4 May 2020 and 16 June 2020. Patients attended preoperative assessment, including coronavirus disease (COVID-19) symptom screening, were instructed to self-isolate for 14 days and had a negative COVID-19 swab within 72 hours of surgery. Patient age, American Society of Anesthesiologists (ASA) grade, body mass index, surgery performed, type of anaesthetic and length of stay were collected. Our primary outcome was a positive COVID-19 swab, secondary outcomes were COVID-19 symptoms, readmission, surgical complications and mortality.
 
  Between 4 May 2020 and 16 June 2020, 191 patients were admitted to three private hospitals for elective surgery; 121 (67%) patients underwent general or regional anaesthetic, 179 patients were ASA grades 1 or 2 (94%) and 12 (6%) were ASA 3. In total, 187 (98%) patients were successfully contacted at 30 days postoperative and no COVID-19 symptoms, positive COVID-19 swabs or mortality or were recorded. One patient was readmitted following a pulmonary embolism and two patients were treated as outpatients for a deep vein thrombosis and a superficial infection.
 
  With 'green pathways' elective orthopaedic surgery can safely be performed while rates of COVID-19 in the community are high.

  Day-case surgery is safe and efficacious for most breast surgical procedures. Limited data exist on its use in immediate breast reconstruction. We present our experience of day-case management of mastectomy with immediate pre-pectoral implant-based reconstruction (IBR).
 
  Data were collected on 47 patients who underwent day-case skin-sparing (SSM) or nipple-sparing (NSM) mastectomy with pre-pectoral IBR between October 2017 and September 2019. Clinicopathological data were collected, including postoperative complications, re-admission and re-operation. The data were compared to published national standards.
 
  Median age was 52 years (range 37-74). Thirty-two patients (68%) had an SSM and 15 (32%) had an NSM. Two patients (4%) had risk-reducing mastectomies and 45 had treatment for invasive cancer or ductal carcinoma in situ (DCIS). Mean tumour size was 33.3mm (range 7-85mm). Forty-two (89%) patients went home on the day of surgery. No patients required re-operation in the first 48 hours. The median postoperative follow-up time was 11.
