    Background: Possible cases of SARS-CoV-2 infection MESHD were diagnosed in primary care in Madrid, some of these cases had pneumonia HP pneumonia MESHD. Most of the SARS-CoV-2 pneumonia MESHD pneumonia HP published data came from hospitalised patients. This study set out to describe clinical characteristics of patients with SARS-CoV-2 pneumonia MESHD pneumonia HP diagnosed in primary care across age groups TRANS and type of pneumonia HP pneumonia MESHD.Methods: Observational retrospective study obtaining clinical data from the electronic health records of patients who were followed-up by SARS-CoV-2 possible infection in a primary care practice in Madrid. All the cases were collected by in-person or remote consultation during the 10th March to the 7th of April. Exposure: Diagnosis of SARS-CoV-2 pneumonia MESHD pneumonia HP by chest X-ray ordered by the GP. Main outcomes and measures: Symptoms of SARS-CoV-2 pneumonia MESHD pneumonia HP, physical examination and diagnostic tests as a blood SERO test, nasopharyngeal swab results for RT-PCR (Reverse transcriptase-polymerase chain reaction) and chest X-ray results. Results: The overall SARS-CoV-2 pneumonias MESHD pneumonias HP collected were 172 ( female TRANS 87 [50.6%], mean age TRANS 60.5 years (standard deviation [SD] 17.0). Comorbidities were body mass index ≥25 kg/m 2 (90 [52.3%]), hypertension HP hypertension MESHD 83 [48.3%]), dyslipidaemia (68 [39.5%]) and diabetes MESHD (33 [19.2%]). The sample was stratified by age groups TRANS (<50 years, 50-75 years and ≥75 years). Clinical manifestations at onset were fever HP fever MESHD (144 [83.7%]), cough HP (140 [81.4%]), dyspnoea MESHD (103 [59.9%]) and gastrointestinal disturbances MESHD (72 [41.9%]). Day 7.8 (SD:4.1) from clinical onset was the mean day of pneumonia HP pneumonia MESHD diagnosis. Bilateral pneumonia MESHD pneumonia HP was more prevalent than unilateral (126 [73.3%]) and 46 [26.7%]). Patients with unilateral pneumonia MESHD pneumonia HP were prone to higher pulse oximetry (96% vs 94%, p <0.001). We found differences between unilateral and bilateral cases in C-reactive protein (29.6 vs 81.5mg/L, p <0.001), and lymphocytes (1400.0 vs 1000.0E3/ml, p<0.001). Complications were registered: 42 (100%) of patients ≥75 years were admitted into hospital; pulmonary embolism HP pulmonary embolism MESHD was only present at bilateral pneumonia HP pneumonia MESHD (7 patients [5.6%]) and death MESHD occurred in 1 patient with unilateral pneumonia MESHD pneumonia HP (2.2%) vs 10 patients (7.9%) with bilateral pneumonia MESHD pneumonia HP ( p 0.170).Conclusion: Clinical manifestations of SARS-CoV-2 pneumonia MESHD pneumonia HP were fever HP fever MESHD, cough HP cough MESHD and dyspnoea; this was especially clear in the elderly TRANS. We described different characteristics between unilateral and bilateral pneumonia MESHD pneumonia HP.

    Objectives: Determine indications and clinical utility of SARS-CoV-2 serology testing in adults TRANS and children TRANS. Design: Prospective evaluation of initial three weeks of a daily Monday to Friday pilot SARS-CoV-2 serology service for patients. Setting: Early post 'first-wave' SARS-CoV-2 transmission TRANS period at single centre London teaching hospital that provides care to the local community, as well as regional and national referral pathways for specialist services. Participants: 110 (72 adults TRANS, 38 children TRANS, age TRANS range 0-83 years, 52.7% female TRANS (n=58)). Interventions: Patient serum SERO from vetted referrals tested on CE marked and internally validated lateral flow immunoassay SERO (LFIA) (SureScreen Diagnostics) detecting antibodies to SARS-CoV-2 SERO spike proteins, with result and clinical interpretation provided to the direct care team. Main outcome measures: Performance SERO characteristics, source and nature of referrals, feasibility and clinical utility of the service, particularly the benefit for clinical decision-making. Results: The LFIA was deemed suitable for clinical advice and decision making following evaluation with 310 serum samples SERO from SARS-CoV-2 PCR positive patients and 300 pre-pandemic samples, giving a sensitivity SERO and specificity of 96.1% and 99.3% respectively. For the pilot, 115 referrals were received leading to 113 tests performed on 108 participants (sample not available for two participants); paediatrics (n=35), medicine (n=69), surgery (n=2) and general practice (n=2). 43.4% participants (n=49) had detectable antibodies to SARS-CoV-2 SERO. There were three main indications for serology; new acute presentations potentially triggered by recent COVID-19 infection e.g. PIMS-TS (n=26) and pulmonary embolism HP pulmonary embolism MESHD (n=5), potential missed diagnoses in context of a recent compatible illness (n=40), and making infection control and immunosuppression treatment decisions in persistently SARS-CoV-2 RNA PCR positive individuals (n=6). Conclusions: This study shows acceptable performance SERO characteristics, feasibility and clinical utility of a SARS-CoV-2 serology service using a rapid, inexpensive and portable assay for adults TRANS and children TRANS presenting with a range of clinical indications. Results correlated closely with a confirmatory in-house ELISA SERO. The study showed the benefit of introducing a serology service where there is a reasonable pre-test probability, and the result can be linked with clinical advice or intervention. Experience thus far is that the volume of requests from hospital referral routes are manageable within existing clinical and laboratory services; however, the demand from community referrals has not yet been assessed. Given recent evidence for a rapid decline in antibodies SERO, particularly following mild infection MESHD, there is likely a limited window of opportunity to realise the benefit of serology testing for individuals infected during the 'first-wave' before they potentially fall HP below a measurable threshold. Rapidly expanding availability of serology services for NHS patients will also help understand the long-term implications of serostatus and prior infection MESHD in different patient groups, particularly before emergence of any 'second-wave' outbreak or introduction of a vaccination programme.

    Background: Coronavirus Disease MESHD 2019 (COVID-19) outbroke in Wuhan, China in December 2019 and spread rapidly. Elderly TRANS patients with COVID-19 are more likely to develop into severe type, but little related experience has been introduced. Case presentation: An 82-year-old female TRANS patient living in Wuhan, China was referred because of fever HP fever MESHD, dry cough MESHD cough HP and chest distress for a week. Clinical diagnosis of COVID-19 was considered, confirmed by viral nucleic acid detection. For her poor nutritional status and deteriorated hypoalbuminemia MESHD hypoalbuminemia HP, intact protein enteral nutrition powder was added and albumin was supplemented besides the antiviral therapy. Her fever HP fever MESHD gradually subsided with the alleviation of related symptoms. During her hospitalization, D-dimer level elevated with ultrasonographically detected thromboembolism HP thromboembolism MESHD in bilateral gastrocnemius veins, and low molecular weight heparin was thereby administrated for the prevention of pulmonary embolism HP pulmonary embolism MESHD. Conclusions: The experience of this case suggested that the timely screening and intervention of malnutrition HP malnutrition MESHD and venous thromboembolism MESHD thromboembolism HP are crucial issues to be concerned when treating elderly TRANS patients with severe COVID-19 besides the routine antiviral therapy.
