The associated mortality with COVID-19 has improved compared with the early pandemic period. The effect of hospital COVID-19 patient prevalence on COVID-19 mortality has not been well studied.

We analysed data for adults with confirmed SARS-CoV-2 infection admitted to 62 hospitals within a multistate health system over 12 months. Mortality was evaluated based on patient demographic and clinical risk factors, COVID-19 hospital prevalence and calendar time period of the admission, using a generalised linear mixed model with site of care as the random effect.

38 104 patients with COVID-19 were hospitalised, and during their encounters, the prevalence of COVID-19 averaged 16% of the total hospitalised population. Between March-April 2020 and January-February 2021, COVID-19 mortality declined from 19% to 12% (p<0.001). In the adjusted multivariable analysis, mid and high COVID-19 inpatient prevalence were associated with a 25% and 41% increase in the odds (absolute contribution to probability of death of nd complexity, such as those experienced during COVID-19 surges.

Diagnostic errors unfortunately remain common. Electronic differential diagnostic support (EDS) systems may help, but it is unclear when and how they ought to be integrated into the diagnostic process.

To explore how much EDS improves diagnostic accuracy, and whether EDS should be used early or late in the diagnostic process.

6 Canadian medical schools. A volunteer sample of 67 medical students, 62 residents in internal medicine or emergency medicine, and 61 practising internists or emergency medicine physicians were recruited in May through June 2020.

Participants were randomised to make use of EDS either early (after the chief complaint) or late (after the complete history and physical is available) in the diagnostic process while solving each of 16 written cases. For each case, we measured the number of diagnoses proposed in the differential diagnosis and how often the correct diagnosis was present within the differential.

EDS increased the number of diagnostic hypotheses by 2.32 (95% CI 2.10 to 2.49) when used early in the process and 0.89 (95% CI 0.69 to 1.10) when used late in the process (both p<0.001). Both early and late use of EDS increased the likelihood of the correct diagnosis being present in the differential (7% and 8%, respectively, both p<0.001). Whereas early use increased the number of diagnostic hypotheses (most notably for students and residents), late use increased the likelihood of the correct diagnosis being present in the differential regardless of one's experience level.

EDS increased the number of diagnostic hypotheses and the likelihood of the correct diagnosis appearing in the differential, and these effects persisted irrespective of whether EDS was used early or late in the diagnostic process.

To evaluate the usefulness of CSF and plasma neurofilament light (Nf-L) as a biomarker for human T-cell lymphotropic virus type 1 (HTLV-1)-associated myelopathy (HAM).

Nf-L, CXCL10, and neopterin were measured by ELISA in 83 CSF samples obtained from 49 individuals living with HTLV-1/2. Plasma Nf-L was also measured by single molecule array. Results were correlated with duration of disease, age, mobility, CSF cell counts, CSF protein, and HTLV-1 proviral load.

Nf-L was detected in all CSF samples (median [range] = 575 [791.8-2,349] pg/mL) and positively correlated with markers of inflammation (CXCL10 (r = 0.733), neopterin (r = 0.499), cell count (r = 0.403), and protein levels (r = 0.693) in CSF;

< 0.0015). There was an inverse correlation between Nf-L and duration of disease (r = -0.584,

< 0.0001). Wheelchair-dependent patients had high concentrations of markers of inflammation and neuronal damage. Concentrations of CXCL10, neopterin, and Nf-L remained elevated in follow-up samples (mean follow-up 5.2 years). Nf-L in plasma correlated with concentration of Nf-L, neopterin, CXCL10, and protein in CSF.

Nf-L in plasma and CSF has potential to be used as a biomarker of disease activity in HAM. Neuronal damage seems to be more intense early in disease but persists long term. Wheelchair-dependent patients have ongoing neuroinflammation.

The new virtual format upended a system that has relied on programmes and applicants balancing the likelihood of acceptance with the financial and time demands of cross-country travel.In this commentary, we address the history of residency interviewing in the USA and the emerging changes that are taking place in light of virtual interviews. We discuss the advantages of the new online format, including the reduced cost for applicants and programmes, as well as the decreased carbon footprint.We also discuss the inequities of virtual interviewing, involving a national maldistribution of interviews to only the top-tier candidates. We share previously unpublished data on the number of virtual interviews accepted by Stanford's 2020 residency applicants, compared with those conducted in person in 2019. We find Stanford applicants in all fields accepted more interviews from a mean of 8 in 2019 to 14 in 2020, a change of 160% on average. Despite this, only half of Stanford 2020 applicants interviewing in the virtual format thought they had accepted more interviews than they would have in person.We comment on how transitions to online interviewing may be affecting medical schools and applicants disproportionately. Ultimately, we highlight the need and offer ideas for additional regulation on behalf of the AAMC to ensure a more equitable distribution of interview opportunities.

Many aspects of the management of neutropenic sepsis remain controversial. These include the choice of empiric antibiotic, the duration of antibiotic therapy and the possibility that very low-risk cases may be managed safely with oral rather than intravenous therapy.

Retrospective cohort study conducted in a district general hospital serving a population of 148 000 in south west Scotland.

Fifty one patients with cancer, whose neutrophil count was less than 1.0×10

/L within 21 days of their last chemotherapy, were admitted as a medical emergency in 2019. All received antibiotic because of presumed neutropenic sepsis. Epacadostat order A total of 4 patients had positive blood cultures (group 1), 12 patients had a clinical focus of infection but no clear pathogen (group 2), while 35 patients had neither (group 3). Group 3 patients were more likely to have a solid tumour, less likely to be febrile, had shorter time to neutrophil recovery and higher Multinational Association of Supportive Care in Cancer scores, though not all of these comparisons achieved statistical significance. Median intravenous plus oral antibiotic duration in group 3 patients was 9 days with median hospital stay of 7 days, raising the possibility of overtreatment. Retrospectively, 23 (66%) group 3 patients had MASSC Risk Index greater than 21 suggesting they were at low risk of complications.

It seems likely that many low-risk neutropenic cancer patients with solid tumours could be managed as effectively and as safely with shorter courses of antibiotic, with oral rather than intravenous antibiotic, as outpatients rather than inpatients and with an overall positive impact on antimicrobial stewardship.

Hypertension is one of the most common comorbidities in COVID-19 pneumonia. However, whether it is an independent factor on the severity and mortality of COVID-19 has not been studied.

In this study, 736 patients with a PCR-confirmed diagnosis of COVID-19 were included from 12 January 2020 to 25 March 2020. All patients were divided into two groups according to whether or not they were hypertensive. After propensity score matching (PSM) to remove the interference of mismatches in the baseline data, the clinical characteristics and outcomes of angiotensin II receptor blocker (ARB)/ACE inhibitors application were analysed.

A total of 220 (29.9%) patients were hypertensive, and 516 (70.1%) patients were not hypertensive. PSM eliminated demographic and comorbidity differences between the two groups. Of all participants, 32 patients died (4.3% mortality), including 17 out of 220 in the hypertension group (7.7%) and 15 out of 516 in the non-hypertension group (2.9%). The incidence of intensive care unit (ICU) stay in the hypertension group (12.8%) was higher than in the non-hypertension group (5.3%) (p<0.05). Logistic regression analysis showed that hypertension was an independent risk factor for death, not other comorbidities. Kaplan-Meier analysis showed that mortality was higher in the hypertension group than in the non-hypertension group before and after PSM (p<0.05). There was no statistically significant difference in ICU therapy, mortality and hospitalisation time between hypertensive patients with or without ARBs/ACE inhibitors (p>0.05).

Hypertension was an independent risk factor for the severity and mortality of patients with COVID-19. ARBs/ACE inhibitors should not be discontinued in hypertensive patients with COVID-19.

White matter lesions (WMLs) are thought to cause damage to the blood-brain barrier, thereby aggravating bleeding after intravenous thrombolysis. However, the risk factors for symptomatic cerebral haemorrhage after thrombolysis are still unclear. This study explored the risk factors for bleeding in patients with severe WMLs after intravenous thrombolysis to prevent bleeding as soon as possible.

A large single-centre observational study conducted a retrospective analysis of intravenous thrombolysis in patients with severe WMLs from January 2018 to March 2021. According to whether symptomatic cerebral haemorrhage occurred, the patients were divided into two groups, and then statistical analysis was performed.

After a retrospective analysis of the data of nearly 1000 patients with intravenous thrombolysis and excluding invalid information, 146 patients were included, of which 23 (15.8%) patients had symptomatic cerebral haemorrhage. Univariate analysis showed that a history of hypertension (20% vs 4.9%, p=0.
