Background Emergence of variants with specific mutations in key epitopes in the spike protein of SARS-CoV-2 raises concerns pertinent to mass vaccination campaigns and use of monoclonal antibodies. We aimed to describe the emergence of the B.1.1.7 variant of concern (VOC), including virological characteristics and clinical severity in contemporaneous patients with and without the variant. Methods In this cohort study, samples positive for SARS-CoV-2 on PCR that were collected from Nov 9, 2020, for patients acutely admitted to one of two hospitals on or before Dec 20, 2020, in London, UK, were sequenced and analysed for the presence of VOC-defining mutations. We fitted Poisson regression models to investigate the association between B.1.1.7 infection and severe disease (defined as point 6 or higher on the WHO ordinal scale within 14 days of symptoms or positive test) and death within 28 days of a positive test and did supplementary genomic analyses in a cohort of chronically shedding patients and in a cohort of remdesivir-treated patients. Viral load was compared by proxy, using PCR cycle threshold values and sequencing read depths. Findings Of 496 patients with samples positive for SARS-CoV-2 on PCR and who met inclusion criteria, 341 had samples that could be sequenced. 198 (58%) of 341 had B.1.1.7 infection and 143 (42%) had non-B.1.1.7 infection. We found no evidence of an association between severe disease and death and lineage (B.1.1.7 vs non-B.1.1.7) in unadjusted analyses (prevalence ratio [PR] 0·97 [95% CI 0·72–1·31]), or in analyses adjusted for hospital, sex, age, comorbidities, and ethnicity (adjusted PR 1·02 [0·76–1·38]). We detected no B.1.1.7 VOC-defining mutations in 123 chronically shedding immunocompromised patients or in 32 remdesivir-treated patients. Viral load by proxy was higher in B.1.1.7 samples than in non-B.1.1.7 samples, as measured by cycle threshold value (mean 28·8 [SD 4·7] vs 32·0 [4·8]; p=0·0085) and genomic read depth (1280 [1004] vs 831 [682]; p=0·0011). Interpretation Emerging evidence exists of increased transmissibility of B.1.1.7, and we found increased virus load by proxy for B.1.1.7 in our data. We did not identify an association of the variant with severe disease in this hospitalised cohort.

Summary Background A small number of medical students elect to work as health care assistants (HCAs) during or prior to their undergraduate training. There is a significant body of evidence in the literature regarding the impact of HCA experience on student nurses; however, little research has examined the effects of such experience on medical students. Methods All fourth‐year medical students with self‐declared experience as HCAs from a single UK medical school were invited to participate in focus groups to explore their experiences and perceptions. Ten students from the year group took part. Results Participants felt that their experience as HCAs enhanced their learning in the workplace through becoming ‘ward smart’, helping them to become socialised into the world of health care, providing early meaningful and humanised patient interaction, and increasing their understanding of multidisciplinary team (MDT) members’ roles. Discussion Becoming ‘ward smart’ and developing a sense of belonging are central to maximising learning in, from and through work on the ward. Experience as a HCA provides a range of learning and social opportunities for medical students, and legitimises their participation within clinical communities. HCA experience also seems to benefit in the ‘hard to reach’ dimensions of medical training: empathy; humanisation of patient care; professional socialisation; and providing a sense of belonging within health care environments.
the 12 item VCDQ; for chronic cough the 19-item LCQ), and patient satisfaction questionnaires and flexible laryngoscopy performed post therapy. Results Eleven people have completed SLT over Skype™ to date, and all demonstrated improvement in symptoms following therapy. Patients with VCD showed a decrease in score on the VCDQ from median (range) 48 (12-53) pre therapy to 40 (7-42) post therapy [minimal clinical important difference (MCID) 5]. Patients with chronic cough showed an increase on the LCQ from median (range) 6.4 (4.6-8.2) pre therapy to 12.2 (10-14.6) post therapy (MCID 1.3). Improvements in laryngeal tension and sensitivity were noted in all cases. All patients gave positive feedback in their patient satisfaction questionnaire scoring "very satisfied" or greater. On three occasions Skype connection problems delayed sessions by a few days. Conclusions Virtual consultations provide the opportunity to treat patients in a more time efficient and practical way, and improvements in patient-reported symptoms and laryngeal appearances were similar to those of patients attending therapy sessions in chest clinic. This data gives support to pursue formalised tariffs for a specialised telehealth service. We feel that Skype should continue as a regular therapy option for patients and other members of the multi-disciplinary team (MDT) should consider this method of therapy delivery. Background BTS guidelines (2008) states that "local anaesthesia (LA) should be used for all arterial blood gas (ABG) specimens except in emergencies 1 as it improves the patient experience. A survey conducted in 2012 revealed only 5% of junior doctors regularly use LA with ABGs. 2 We were interested to determine if this has improved and establish whether medical students are being orientated to this practice. Methodology This is a multicentre prospective study. A questionnaire survey was distributed to 4th year medical students and junior doctors affiliated with UCL Medical School. Questions related to their actual experiences of using LA with ABGs and barriers to using LA. Results 94 medical students completed the questionnaire. Students used LA 17% of the time out of 54 supervised procedures. 29% were actively discouraged from using LA by their supervising doctor. 10% felt the general culture amongst supervising doctors was resistant to using LA. P113Amongst the 86 surveyed doctors, 91% never or rarely (<10% of the time) used LA, 5% sometimes (<25% of the time) and 3% used it regularly (>75% of the time). 65% of doctors were not aware that LA was advised in national guidance. 40% of respondents felt it would not reduce the pain of the procedure and 38% did not know the technique involved of using LA. Conclusion The use of LA is extremely poor as has been found previously.1 The reasons reflect a lack of awareness and a culture that is experienced from the moment the enter the clinical environment as medical students. In order to improve the
Patients with certain neurological diseases are at increased risk of developing chest infections as well as respiratory failure due to muscular weakness. In particular, patients with certain neuromuscular disorders are at higher risk. These conditions are often associated with sleep disordered breathing. It is important to identify patients at risk of respiratory complications early in the course of their disease, although patients with neuromuscular disorders often present in the acute setting with respiratory involvement. This review of the respiratory complications of neurological disorders, with a particular focus on neuromuscular disorders, explores why this happens and looks at how to recognize, investigate, and manage these patients effectively.
A woman in her 40s originally from Zimbabwe presented to our accident department in the UK with a 4 day history of menorrhagia and exertional chest pain. Her clinical examination was unremarkable. Routine blood tests revealed a haemoglobin value of 6.8 g/dl and a platelet count of 15×10(9)/l, with normal renal function and coagulation profile. Blood film showed microangiopathic haemolytic anaemia and thrombocytopenia. On direct questioning, she admitted to being HIV positive, and receiving antiviral therapy at another hospital. A diagnosis of HIV associated thrombotic thrombocytopenic purpura (TTP) was made. The patient was transferred to a tertiary centre for urgent plasma exchange. She required 8 days of 1.5 litre exchanges with solvent detergent fresh frozen plasma (FFP) and high dose steroids. She responded within 24 h with increasing haemoglobin and platelet counts, and at discharge her haemoglobin was 10.7 g/dl and platelet count 253×10(9)/l.
