Introduction
Postoperative delirium (POD) is a common and serious complication in older adult patients undergoing cardiovascular surgery. Esketamine is known for its anti-inflammatory and neuroprotective properties. While it has shown preventive effects on POD in those not undergoing cardiovascular surgery, its efficacy in older adult patients undergoing cardiovascular surgery remains uncertain. Therefore, we herein aimed to evaluate the preventive effect of intraoperative subanaesthetic esketamine on POD in this specific population.

Methods and analysis
This single-centre, randomised, double-blind, placebo-controlled trial will enrol 778 patients aged 60–80 years undergoing open-heart cardiovascular surgery in China, from September 2023 to December 2025. The participants will be randomly assigned in a 1:1 ratio to the following groups: the esketamine group and the control group. In the esketamine group, esketamine (2 mg/mL) will be administered intravenously at a dosage of 0.3 mg/kg over 10 min following tracheal intubation, followed by a continuous infusion at 0.15 mg/kg/h until the end of the surgery. Patients in the control group will receive a placebo following the same dosage and regimen. The incidence of POD will be the primary outcome and will be assessed twice daily from the first to the seventh postoperative day. The postoperative sleep quality, duration of postoperative mechanical ventilation, and length of hospital and intensive care unit stay will be the secondary outcomes.

Ethics and dissemination
Ethical approval was obtained from the Institutional Review Board of Fuwai Central China Cardiovascular Hospital (No. 2023068). Public disclosure is guaranteed post-trial, and the results will be published in a peer-reviewed scientific journal.

While the adenoma detection rate (ADR) is associated with post-colonoscopy colorectal cancer (PCCRC) risk, it is unknown to what extent this reflects missed colorectal cancer (CRC) versus missed pre-cancerous lesions. We evaluated the association between physician ADR and prevalent CRC detection during colonoscopy.

Stroke, Ahead of Print. BACKGROUND:Neuronal plasticity after stroke occurs predominantly within the first few months. However, its persistence and distribution in the chronic phase remain unclear. This study investigated longitudinal changes in cortical gray matter and corticospinal tract integrity beyond 6 months poststroke and their associations with chronic upper limb motor outcomes.METHODS:We conducted a retrospective cohort study at St. Vincent’s Hospital (Suwon, Republic of Korea) between 2015 and 2022, including patients with first-ever unilateral stroke who underwent at least 2 magnetic resonance imaging scans ≥6 months post-onset. Gray matter volume in cerebral and cerebellar cortices was assessed using 3-dimensional T1-weighted imaging and corticospinal tract integrity via diffusion tensor tractography. Hemispheres were classified as affected or unaffected based on anatomic connectivity to the lesion. Upper limb motor score was measured using a 5-stage ordinal scale and grouped into 3 categories by hand function: poor (no movement), partial (limited movement), and good (fully functional use). Ordinal logistic regression identified structural predictors of motor outcomes, adjusting for age, sex, lesion volume, and baseline impairment.RESULTS:Among 62 patients, structural plasticity persisted beyond 6 months in a subset of patients. Imaging was conducted at an average of 51 months poststroke (range, 13–137 months). Increases in affected cerebellar gray matter were associated with better motor outcomes (odds ratio, 0.67 [95% CI, 0.48–0.92];P=0.01). The odds ratio

Introduction
Neck pain is highly prevalent worldwide with no reliable or approved therapies. Recently, percutaneous neuromodulation (PNM) has gained popularity as an alternative to conventional treatments for managing musculoskeletal disorders.

Objective
This study aims to assess the comparative effectiveness of PNM compared with therapeutic exercise in the management of patients with chronic non-specific neck pain (CNNP).

Methods and analysis
In this randomised, controlled, single-blind study, 100 patients with CNNP will be allocated in a 1:1 ratio into two study groups: treatment with PNM and treatment with therapeutic exercise (specific neck exercises). A total of 18 structured exercise sessions will be administered three times per week for 6 weeks. Disability, pain intensity, fear of movement, quality of life, quality of sleep, catastrophising, cervical range of motion and pressure pain threshold will be recorded at 6 weeks (immediately post-treatment) and 8 weeks after initiation (or the end of treatment).

Ethics and dissemination
Ethical approval was obtained from the provincial research ethics committee of Almeria (AP-0429-2023 C4-F2) in June 2024. The results of the study, including feasibility outcomes, will be published in peer-reviewed journals and presented at academic, clinical and healthcare conferences.

Introduction
Diabetes during pregnancy poses significant health risks for both mothers and their offspring and requires comprehensive management throughout pregnancy and the postpartum period. The increasing global prevalence of diabetes during pregnancy requires effective and efficient management. The current healthcare system can be challenging because of need for frequent hospital visits and limited availability of gestational diabetes (GDM) specialists.
This study investigates the impact of a digital-based management system designed to support women with diabetes from pregnancy through the first year post partum. This system includes a mobile application (MomStart) that allows users to log health data, receive tailored educational content and communicate with healthcare providers. The primary objective of this study is to compare pregnancy outcomes with historical data. We will also investigate the usability of the MomStart application.

Methods and analysis
The study will enrol over 100 pregnant women with diabetes from two hospitals in South Korea for the main study and an additional 500 women from across the country for a supplementary usability study. Data will be collected and analysed to assess neonatal and maternal outcomes and the app’s retention and satisfaction rates.

Ethics and dissemination
The protocol was approved by the Institutional Review Board of the Catholic University of Korea (XC23OIDI0012). We will present our findings in a national conference and in peer-reviewed medical journals.

Clinical study registration number
This study was registered in Korea’s Clinical Research Information Service system (KCT0008483).

Objectives
To determine if carer administration of as-needed subcutaneous medication for common breakthrough symptoms in people dying at home is feasible and acceptable in the UK, and if it would be feasible to test this intervention in a future definitive randomised controlled trial.

Design
We conducted a two-arm, parallel-group, individually randomised, open pilot trial of the intervention versus usual care, with a 1:1 allocation ratio, using convergent mixed methods.

Setting
Home-based care without 24/7 paid care provision, in three UK sites.

Participants
Participants were dyads of adult patients and carers: patients in the last weeks of their life who wished to die at home and lay carers who were willing to be trained to give subcutaneous medication. Strict risk assessment criteria needed to be met before the approach, including a known history of substance abuse or carer ability to be trained to competency.

Intervention
Intervention-group carers received training by local nurses using a manualised training package.

Primary outcome measures
Quantitative data were collected at baseline and 6–8 weeks post-bereavement and via carer diaries. Interviews with carers and healthcare professionals explored attitudes to, experiences of and preferences for giving subcutaneous medication and experience of trial processes. The main outcomes of interest were feasibility, acceptability, recruitment rates, attrition and selection of the most appropriate outcome measures.

Secondary outcome measures
The secondary outcome measure was time to symptom relief, calculated using data items from the carer diary, after the patient had died.

Results
In total, 40 out of 101 eligible dyads were recruited (39.6%), which met the feasibility criterion of recruiting >30% of eligible dyads. The expected recruitment target (50 dyads) was not reached, as fewer than expected participants were identified. Although the overall retention rate was 55% (22/40), this was substantially unbalanced (30% (6/20) usual care and 80% (16/20) intervention). The feasibility criterion of >40% retention was, therefore, considered not met. A total of 12 carers (intervention, n=10; usual care, n=2) and 20 healthcare professionals were interviewed. The intervention was considered acceptable, feasible and safe in the small study population. The intervention group had a considerably shorter time to medication administration than the usual-care group (median time to administer medication in intervention=5 min, usual-care=105 min). Intervention group carers felt confident in administering medication. Healthcare professional support was sought by intervention group carers in 24 out of 147 (16.3%) medication administration entries. The context of the feasibility study was not ideal, as district nurses were overstretched, unfamiliar with research methods and possibly not in equipoise. A disparity in readiness to consider the intervention was demonstrated between carers, who were uniformly enthusiastic, and healthcare professionals who were not. Findings confirmed methodological and ethics issues pertaining to researching the last days of life care.

Conclusion
The success of a future definitive trial is uncertain because of equivocal results in the progression criteria, particularly poor recruitment overall and a low retention rate in the usual-care group. Future work regarding the intervention should include understanding the context of UK areas where this has been adopted, ascertaining wider public views and exploring healthcare professional views on burden and risk in the NHS context. There should be consideration of the need for national policy and the most appropriate quantitative outcome measures to use. This will help to ascertain if there are unanswered questions to be studied in a trial.

Objectives
To evaluate the impact and acceptability of a tailored, gender-responsive behavioural activation (BA) intervention for improving depression and anxiety in male National Health Service (NHS) frontline workers.

Design
Pre-post intervention study.

Setting
Three NHS organisations in the North of England.

Participants
45 men aged ≥18 years working in a frontline NHS role scoring in the subclinical range (5–14) on the Patient Health Questionnaire-9 (PHQ-9) (depression) and/or the Generalised Anxiety Disorder-7 (GAD-7) (anxiety) at baseline.

Interventions
A tailored BA treatment programme consisting of up to eight telephone support sessions over a period of 4–6 weeks, accompanied by a BA self-help manual.

Main outcome measures
Self-reported symptom severity of depression, assessed by PHQ-9, and anxiety, assessed by GAD-7, at baseline and 4 and 6 months. Acceptability from the perspectives of male study participants and coaches who delivered the intervention was assessed in a nested qualitative study using the theoretical framework of acceptability (TFA).

Results
PHQ-9 and GAD-7 scores decreased from baseline to 4 months on both the PHQ-9 and GAD-7. While scores increased from 4 months to 6 months, the 6-month scores remained below those of the baseline scores. Acceptability of the intervention was high across all constructs of the TFA. The practical and action-oriented strategies of the intervention, and the confidential, flexible, convenient mode of delivery, worked to support men’s engagement with the intervention.

Conclusions
Delivery of a tailored, gender-responsive BA intervention was appealing to, and beneficial for, men working in frontline NHS roles with less severe depression and anxiety. The BALM intervention offers promise as a tailored workplace mental health programme that is aligned with men’s needs and preferences and can help overcome a reticence to engage with mental health support in NHS staff and beyond.

Stroke, Ahead of Print. BACKGROUND:Ischemic stroke poses a significant threat to human health. FGF (fibroblast growth factor) 20 is involved in the repair of central nervous system diseases, but it has the shortcomings of short half-life and inability to penetrate the blood-brain barrier. Therefore, to overcome the drawbacks of rhFGF20 (recombinant human FGF20) and explore its role in ischemic stroke, the effects of intracerebral administration of rhFGF20 by heparin-poloxamer hydrogel (HP-rhFGF20 [heparin-poloxamer hydrogel-encapsulated rhFGF20]) in a rat stroke model were the focus of this study.METHODS:A rat model of middle cerebral artery occlusion/reperfusion and oxygen-glucose deprivation-reoxygenation models were established to mimic ischemic stroke in vivo and in vitro, respectively. Endogenous FGF20 levels were measured in patients, ischemic rats, and oxygen-glucose deprivation-reoxygenation–injured neurons. To assess the therapeutic potential, rhFGF20 was administered intracerebrally via heparin-poloxamer hydrogel implants (1 mg/mL, 20 μL) on day 5 poststroke. TTC staining, neurobehavioral tests (including the mNSS test, the corner test, the rotarod test, the cylinder test, and the Morris water maze test), and Nissl staining were performed to evaluate neurological recovery. Immunofluorescence and Western blotting were conducted to assess the brain repair processes (neurogenesis, neuronal remodeling, and angiogenesis).RESULTS:High expression of FGF20 was detected in the serum of patients with ischemic stroke, the cortex of ischemic rats, and oxygen-glucose deprivation-reoxygenation–injured neurons. Heparin-poloxamer increased the stability and bioavailability of rhFGF20. HP-rhFGF20 attenuated neurobehavioral deficits and infarct volume in ischemic stroke rats. HP-rhFGF20 inhibited neuronal cell death, microglial activation, and glial scar formation on day 7 post-implantation. Moreover, HP-rhFGF20 promoted the proliferation, migration, and differentiation of neural stem cells and improved neuronal plasticity and angiogenesis in ischemic stroke rats.CONCLUSIONS:HP-rhFGF20 promoted functional recovery in ischemic stroke rats by enhancing neurogenesis and angiogenesis. The combination of growth factors and biomaterials provides a promising therapeutic strategy for central nervous system diseases.REGISTRATION:URL:http://www.chictr.org.cn; Unique identifier: ChiCTR2100051104.

Stroke, Ahead of Print. BACKGROUND:Early reocclusion following successful recanalization through mechanical thrombectomy is linked to poor clinical outcomes in patients with stroke with intracranial atherosclerotic occlusion (ICAS-O). However, the factors influencing early reocclusion remain inadequately understood. This study is a post hoc analysis of 24-hour reocclusion in patients with successfully recanalized ICAS-O from a multicenter trial.METHODS:Patients with successfully recanalized ICAS-O were selected from the ANGEL-REBOOT trial (Randomized Study of Bailout Intracranial Angioplasty Following Thrombectomy for Acute Large Vessel Occlusion). Reocclusion was defined as a 24-hour arterial occlusive lesion score of 0 to 1, determined by magnetic resonance or computed tomography angiography. Possible factors associated with early reocclusion were screened through univariable analysis, and then, multivariable logistic regression was used to identify independent factors associated with early reocclusion.RESULTS:Among the 348 patients in the ANGEL-REBOOT trial, 21 could not be diagnosed with ICAS-O, 14 failed recanalization by the end of the procedure, and 14 had no follow-up angiography data. Finally, a total of 299 subjects were included, with a median age of 63 (interquartile range, 55–69) years, and 77 of 299 (25.75%) were females. The 24-hour reocclusion rate was 9.7% (29/299). Through backward elimination, 3 independent factors remained in the final multivariable logistic regression model. Specifically, puncture-to-recanalization time (per hour increase: odds ratio, 1.80 [95% CI, 1.31–2.47]) was positively associated with reocclusion, while general anesthesia (odds ratio, 0.25 [95% CI, 0.10–0.65]) and a postprocedural expanded Thrombolysis in Cerebral Infarction score of 2c-3 (odds ratio, 0.35 [95% CI, 0.14–0.85]) were negatively associated with reocclusion. Compared with patients without reocclusion, those with reocclusion had significantly greater 90-day modified Rankin Scale scores (median 4 versus 1, Mann-WhitneyUtest;P

Background
Recent meta-analyses suggested diclofenac may be superior to indomethacin in preventing post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP). The aim of our study was to compare the efficacy of 100 mg rectal indomethacin versus diclofenac on PEP incidences.

Design
This multicentre, double-blinded, randomised controlled trial was conducted in nine tertiary centres in China. Patients with low and high risk for PEP and native papilla were randomly allocated (1:1) to receive 100 mg diclofenac or 100 mg indomethacin rectally before ERCP. The primary outcome was the occurrence of PEP defined by the Cotton consensus. The intention-to-treat principle was conducted for the analysis.

Results
The trial was terminated early for futility after the predetermined first interim analysis. Between June 2023 and May 2024, 1204 patients were randomised into the diclofenac group (n=600) or indomethacin group (n=604). Baseline characteristics were balanced. The primary outcome occurred in 53 patients (8.8%) of 600 patients allocated to the diclofenac group and 37 patients (6.1%) of 604 patients allocated to the indomethacin group (relative risk 1.44; 95% CI 0.96 to 2.16, p=0.074). PEP occurred in 35 (14.2%) of 247 high-risk patients in the diclofenac group and 26 (9.8%) of 266 high-risk patients in the indomethacin group (p=0.124). PEP incidences were also comparable in low-risk patients between the two groups (18/353 (5.1%) vs 11/338 (3.3%), p=0.227). Other ERCP-related complications did not differ between the two groups.

Conclusion
Pre-procedure 100 mg rectal diclofenac was not superior to the same dose of rectal indomethacin regarding preventing PEP. These findings supported current clinical practice guidelines of 100 mg indomethacin or diclofenac for PEP prophylaxis in patients without contraindications.

Background
Mast cell activation is an important driver of abdominal pain in irritable bowel syndrome (IBS). While evidence supports the role of IgE-mediated mast cell activation in visceral pain development in IBS, the role of pseudoallergic MRGPRX2-mediated mast cell activation in this process remains unknown.

Objective
We investigated whether MRGPRX2-mediated mast cell activation plays a role in abdominal pain development in patients with IBS.

Design
MRGPRX2 expression in mast cells and other immune cells was characterised across colon layers using flow cytometry. We evaluated whether MRGPRX2 agonists trigger mast cell degranulation and transient receptor potential vanilloid 1 (TRPV1) sensitisation in healthy human colonic submucosal plexus samples using live imaging. Rectal biopsies were then collected from patients with IBS and healthy volunteers (HV) and MRGPRX2+ mast cell frequency, MRGPRX2 expression per cell, mast cell degranulation kinetics in response to MRGPRX2 agonists, MRGPRX2 agonistic activity and presence of MRGPRX2 agonists in biopsy supernatants were assessed.

Results
MRGPRX2+ mast cells are enriched in the submucosa and muscularis of the healthy human colon. MRGPRX2 agonists induce mast cell degranulation and TRPV1 sensitisation in the healthy colon submucosa. While the frequency of rectal MRGPRX2+ mast cells was unaltered in IBS, submucosal mast cells showed increased degranulation in response to MRGPRX2 agonists in IBS compared with HV. MRGPRX2 agonistic activity was increased in IBS rectal biopsy supernatant compared with HV, which was associated with increased levels of substance P.

Conclusion
The MRGPRX2 pathway is functionally upregulated in the colon of patients with IBS, supporting its role in abdominal pain in IBS.

Introduction
Spinal cord injury (SCI) has been linked to increased frequencies of sleep-related breathing disorders (SRBDs) (≤50% after paraplegia and ≤90% following tetraplegia). However, SRBDs have been under-recognised and undertreated among individuals with SCI. The OPTIMISE SCI (Outcomes Post Treatment: Impact on Motor Impairment of Sleep Efficiency in SCI) is an ongoing phase 3 clinical trial focused on the effects of the early use of continuous positive airway pressure (CPAP) therapy to treat individuals with moderate-to-severe SRBDs in the acute/subacute stage after SCI.

Methods and analysis
A total of 44 participants with SCI who are newly diagnosed with moderate-to-severe SRBD are randomised into early CPAP therapy (initiated within the first 8 weeks postinjury) versus delayed CPAP therapy (initiated at 6 months postinjury). Participants with no/mild SRBDs are included in the control group (n=22). Primary outcome measures include neurological and functional recovery after SCI.

Ethics and dissemination
The protocol for this randomised clinical trial (RCT) raised an interesting discussion with our research ethics board about delaying CPAP therapy by 3 months when a participant is diagnosed with moderate-to-severe SRBD. Given that the current standard of care does not include screening for SRBDs in individuals who are admitted for spinal cord rehabilitation, most individuals are screened for SRBDs during the chronic stage post-SCI, which represents a greater delay in the diagnosis and treatment of SRBDs in this population. Because the potential impact of the OPTIMISE SCI trial on the current standard of care outweighs the risk of delaying CPAP therapy by 3 months, this trial protocol was approved. The dissemination plan includes presentations at scientific meetings and publication of the results in a peer-reviewed scientific journal.

Objectives
Prediction models for post-stroke mortality can support medical decision-making. Although numerous models have been developed, external validation studies determining the models’ transportability beyond the original settings are lacking. We aimed to assess the performance of two prediction models for post-stroke mortality in Berlin, Germany.

Design
We used data from the Berlin-SPecific Acute Treatment in Ischaemic or hAemorrhagic stroke with Long-term follow-up (B-SPATIAL) registry.

Setting
Multicentre stroke registry in Berlin, Germany.

Participants
Adult patients admitted within 6 hours after symptom onset and with a 10th revision of the International Classification of Diseases discharge diagnosis of ischaemic stroke, haemorrhagic stroke or transient ischaemic attack at one of 15 hospitals with stroke units between 1 January 2016 and 31 January 2021.

Primary outcome measures
We evaluated calibration (calibration-in-the-large, intercept, slope and plot) and discrimination performance (c-statistic) of Bray et al’s 30-day mortality and Smith et al’s in-hospital mortality prediction models. Information on mortality was supplemented by Berlin city registration office records.

Results
For the validation of Bray et al’s model, we included 7879 patients (mean age 75; 55.0% men). We observed 763 (9.7%) deaths within 30 days of stroke compared with 680 (8.6%) predicted. The model’s c-statistic was 0.865 (95% CI: 0.851 to 0.879). For Smith et al’s model, we performed the validation among 1931 patients (mean age 75; 56.2% men), observing 105 (5.4%) in-hospital deaths compared with the 92 (4.8%) predicted. The c-statistic was 0.891 (95% CI: 0.864 to 0.918). The calibration plots of both models revealed an underestimation of the mortality risk for high-risk patients.

Conclusions
Among Berlin stroke patients, both models showed good calibration performance for low and medium-risk patients and high discrimination while underestimating risk among high-risk patients. The acceptable performance of Bray et al’s model in Berlin illustrates how a small number of routinely collected variables can be sufficient for valid prediction of post-stroke mortality.

Introduction
Hypernatraemia, defined as a plasma sodium concentration >145 mmol/L, is a frequent complication in critically ill patients treated in the intensive care unit (ICU) (= ICU-acquired hypernatraemia), with reported prevalence ranging from 4% to 26%. Hypernatraemia adversely affects various physiological functions and is associated with delirium, prolonged length of stay and increased ICU and post-discharge mortality. The sodium load from intravenous drug diluents significantly contributes to ICU-acquired hypernatraemia, with drug infusions comprising about 30% of the daily fluid volume of an average ICU patient. This study aims to investigate if using glucose 5% solution as the default drug diluent, instead of sodium chloride 0.9%, can reduce the prevalence of ICU-acquired hypernatraemia and improve patient outcomes.

Methods and analysis
To test the effectiveness of glucose 5% solution as the default drug diluent, we will conduct a multicentre, pragmatic, embedded, open-label, stepped-wedge, cluster-randomised trial. The study will include twelve clusters (ICUs and one intermediate care unit) across six hospitals in Germany, with a projected total sample size of 4485 patients. In line with the stepped-wedge cluster-randomised design, one ICU will transition every 4 weeks, in a randomised sequence, from using sodium chloride 0.9% as the default drug diluent to glucose 5%.
The primary endpoint is the prevalence of hypernatraemia >150 mmol/L through day 28. The number of days alive and free of the ICU through day 28 will be tested hierarchically as a key secondary endpoint. Other exploratory endpoints include ICU mortality, ICU-free days, hospital-free days and other clinical outcomes. The primary endpoint will be analysed using a logistic mixed-effects model.

Ethics and dissemination
The trial was approved by the Charité—Universitätsmedizin Berlin Ethics Board and by the ethics board of each enrolled hospital. The results will be submitted for publication in a peer-reviewed journal and presented at one or more scientific conferences.

Trial registration number
The trial protocol was registered with the German Clinical Trials Register on 21 June 2024 prior to initiation of patient enrolment (DRKS00033397).

Purpose
The pathogenesis of the long-lasting symptoms which can follow an infection with the SARS-CoV-2 virus (‘long covid’) is not fully understood. The ‘COroNaVirus post-Acute Long-term EffectS: Constructing an evidENCE base’ (CONVALESCENCE) study was established as part of the Longitudinal Health and Wellbeing COVID-19 UK National Core Study. We performed a deep phenotyping case-control study nested within two cohorts (the Avon Longitudinal Study of Parents and Children and TwinsUK) as part of CONVALESCENCE.

Participants
From September 2021 to May 2023, 349 participants attended the CONVALESCENCE deep phenotyping clinic at University College London. Four categories of participants were recruited: cases of long covid (long covid(+)/SARS-CoV-2(+)), alongside three control groups: those with neither long covid symptoms nor evidence of prior COVID-19 (long covid(-)/SARS-CoV-2(-); control group 1), those who self-reported COVID-19 and had evidence of SARS-CoV-2 infection, but did not report long covid (long covid(-)/SARS-CoV-2(+); control group 2) and those who self-reported persistent symptoms attributable to COVID-19 but no evidence of SARS-CoV-2 infection (long covid(+)/SARS-CoV-2(-); control group 3). Remote wearable measurements were performed up until February 2024.

Findings to date
This cohort profile describes the baseline characteristics of the CONVALESCENCE cohort. Of the 349 participants, 141 (53±15 years old; 21 (15%) men) were cases, 89 (55±16 years old; 11 (12%) men) were in control group 1, 75 (49±15 years old; 25 (33%) men) were in control group 2 and 44 (55±16 years old; 9 (21%) men) were in control group 3.

Future plans
The study aims to use a multiorgan score calculated as the cumulative total for each of nine domains (ie, lung, vascular, heart, kidney, brain, autonomic function, muscle strength, exercise capacity and physical performance). The availability of data preceding acute COVID-19 infection in cohorts may help identify the consequences of infection independent of pre-existing subclinical disease and also provide evidence of determinants that influence the development of long covid.
