Mortality and pulmonary complications in patients undergoing surgery with perioperative SARS-CoV-2 infection: an international cohort study

Background: The impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on postoperative recovery needs to be understood to inform clinical decision making during and after the COVID-19 pandemic. This study reports 30-day mortality and pulmonary complication rates in patients with perioperative SARS-CoV-2 infection. Methods: This international, multicentre, cohort study at 235 hospitals in 24 countries included all patients undergoing surgery who had SARS-CoV-2 infection confirmed within 7 days before or 30 days after surgery. The primary outcome measure was 30-day postoperative mortality and was assessed in all enrolled patients. The main secondary outcome measure was pulmonary complications, defined as pneumonia, acute respiratory distress syndrome, or unexpected postoperative ventilation. Findings: This analysis includes 1128 patients who had surgery between Jan 1 and March 31, 2020, of whom 835 (74·0%) had emergency surgery and 280 (24·8%) had elective surgery. SARS-CoV-2 infection was confirmed preoperatively in 294 (26·1%) patients. 30-day mortality was 23·8% (268 of 1128). Pulmonary complications occurred in 577 (51·2%) of 1128 patients; 30-day mortality in these patients was 38·0% (219 of 577), accounting for 81·7% (219 of 268) of all deaths. In adjusted analyses, 30-day mortality was associated with male sex (odds ratio 1·75 [95% CI 1·28–2·40], p\textless0·0001), age 70 years or older versus younger than 70 years (2·30 [1·65–3·22], p\textless0·0001), American Society of Anesthesiologists grades 3–5 versus grades 1–2 (2·35 [1·57–3·53], p\textless0·0001), malignant versus benign or obstetric diagnosis (1·55 [1·01–2·39], p=0·046), emergency versus elective surgery (1·67 [1·06–2·63], p=0·026), and major versus minor surgery (1·52 [1·01–2·31], p=0·047). Interpretation: Postoperative pulmonary complications occur in half of patients with perioperative SARS-CoV-2 infection and are associated with high mortality. Thresholds for surgery during the COVID-19 pandemic should be higher than during normal practice, particularly in men aged 70 years and older. Consideration should be given for postponing non-urgent procedures and promoting non-operative treatment to delay or avoid the need for surgery.

Impacts of the Covid-19 Pandemic on Criminal Justice Journeys of Adult and Child Survivors of Sexual Abuse, Rape and Sexual Assault, 2020-2022

Over 150,000 sexual offences were recorded by police in year ending March 2020 (ONS, 2020), and there are indications that the Covid-19 lockdown increased some sexual offences (e.g. online -facilitated abuse, or sexual abuse perpetrated by family members) and decreased others (e.g. assaults by strangers/peers). However, there has been no research into the specific effects of Covid-19 on criminal justice system (CJS) policies and practices relating to sexual offences, nor on the journeys of survivors through the CJS during this period. Prior to the pandemic, there were significant challenges for the investigation and prosecution of sexual offences and conviction rates were extremely low. Some of these challenges may well have been exacerbated by Covid-19 and lockdown e.g. further delays to investigating cases, postponement of Achieving Best Evidence interviews. At the same time, however, Covid-19 has generated significant innovation within the CJS, e.g. the introduction of a video platform within the courts enabling all parties in a criminal hearing to engage securely and remotely, and this may sow the seeds for improvement in survivors’ journeys through the CJS. Drawing on the perspectives and experiences of CJS stakeholders, including complainants and families, police, Crown Prosecution Service, HM Courts and Tribunals Services, the Judiciary, Sexual Assault Referral Centres (SARCs), and Independent Sexual Violence Advisors, this project provide unique insights into the impact of the pandemic on the CJS in sexual offence cases. The data shared here is based on 72 interviews conducted with survivors/family members, and professionals from the police, SARCs and the third sector. The findings identify how the pandemic has exacerbated existing challenges, posed new difficulties, and provoked innovations that could improve the experiences of victims and survivors of sexual violence and abuse.Over 150,000 sexual offences were recorded by the police in the year ending March 2020 (ONS, 2020), and there are indications that lockdown increased some sexual offences (e.g. online-facilitated abuse, sexual abuse perpetrated by family members) and decreased others (e.g. assaults by strangers/peers).

Changes to procedures precipitated by Covid-19 might offer longer-term benefits for survivors and stakeholders and we aim to identify these and promote their implementation.</p

Data from: Newly discovered morphology of the Silurian sea spider Haliestes and its implications

The three-dimensionally preserved Haliestes dasos from the Silurian (Wenlock) Lagerstätte is the most complete fossil sea spider and the oldest unambiguous pycnogonid known from the fossil record. The discovery of two new specimens to add to the holotype reveals new features including proximal annulations of the appendages and segmentation of the trunk end, critical details for comparison with pycnogonids from the Devonian (Emsian) Hunsrück Slate and for the interpretation of the evolutionary significance of Palaeozoic genera. There is some evidence of sexual dimorphism. H. dasos was nektobenthic and its morphology indicates an unusual mode of feeding compared to living pycnogonids. The new morphological features of H. dasos are closely similar to those in Palaeoisopus problematicus from the Hunsrück Slate and it clearly belongs, together with that species, in stem Pycnogonida and not the crown group

Supplementary information files for article What have we learnt from quantitative case reports of acute lateral ankle sprains injuries and episodes of ‘giving-way’ of the ankle joint, and what shall we further investigate? Lateral ankle sprains are a commonly incurred injury in sports. They have a high recurrence rate and can lead to the development of persistent injury associated symptoms. We performed a quantitative synthesis of published case reports documenting the kinematics of acute lateral ankle sprains and episodes of “giving-way” of the ankle joint to provide a comprehensive description of the mechanisms. A systematic literature search was conducted to screen records within MEDLINE® and EMBASE® . Additional strategies included manual search of specific journals as well as contacting researchers in relevant communities to retrieve unpublished data. Twenty-four cases were included in the quantitative synthesis; 11 from individual case reports and 13 from four separate case series. Two authors independently reviewed all articles and extracted ankle joint kinematic data. Excessive ankle inversion was the most pronounced kinematic pattern observed across all included cases, with a mean peak inversion angle of 67.5° (range 2.0 to 142) and a mean peak inversion velocity of 974°/s (range 468 to 1752). This was followed by internal rotation and plantar flexion, respectively. A homogeneous linear function revealed a mean inversion velocity across all cases of 337°/s (range 117 to 1400; R2 =0.78; p&lt;0.0001)
