RESUMO
Studies on brain abscess are hampered by single-centre design with limited sample size and incomplete follow-up. Thus, robust analyses on clinical prognostic factors remain scarce. This Danish nationwide, population-based cohort study included clinical details of all adults (≥18 years) diagnosed with brain abscess in the Danish National Patient Registry from 2007 through 2014 and the prospective clinical database of the Danish Study Group of Infections of the Brain covering all Danish departments of infectious diseases from 2015 through 2020. All patients were followed for 6 months after discharge. Prognostic factors for mortality at 6 months after discharge were examined by adjusted modified Poisson regression to compute relative risks with 95% confidence intervals (CI). Among 485 identified cases, the median age was 59 years [interquartile range (IQR 48-67)] and 167 (34%) were female. The incidence of brain abscess increased from 0.4 in 2007 to 0.8 per 100 000 adults in 2020. Immuno-compromise was prevalent in 192/485 (40%) and the clinical presentation was predominated by neurological deficits 396/485 (82%), headache 270/411 (66%), and fever 208/382 (54%). The median time from admission until first brain imaging was 4.8 h (IQR 1.4-27). Underlying conditions included dental infections 91/485 (19%) and ear, nose and throat infections 67/485 (14%), and the most frequent pathogens were oral cavity bacteria (59%), Staphylococcus aureus (6%), and Enterobacteriaceae (3%). Neurosurgical interventions comprised aspiration 356/485 (73%) or excision 7/485 (1%) and was preceded by antibiotics in 377/459 (82%). Fatal outcome increased from 29/485 (6%) at discharge to 56/485 (12%) 6 months thereafter. Adjusted relative risks for mortality at 6 months after discharge was 3.48 (95% CI 1.92-6.34) for intraventricular rupture, 2.84 (95% CI 1.45-5.56) for immunocompromise, 2.18 (95% CI 1.21-3.91) for age >65 years, 1.81 (95% CI 1.00-3.28) for abscess diameter >3 cm, and 0.31 (95% CI 0.16-0.61) for oral cavity bacteria as causative pathogen. Sex, neurosurgical treatment, antibiotics before neurosurgery, and corticosteroids were not associated with mortality. This study suggests that prevention of rupture of brain abscess is crucial. Yet, antibiotics may be withheld until neurosurgery, if planned within a reasonable time period (e.g. 24 h), in some clinically stable patients. Adjunctive corticosteroids for symptomatic perifocal brain oedema was not associated with increased mortality.

BACKGROUND: Human immunodeficiency virus (HIV) infection is associated with depression. However, previous studies have not addressed familial factors. METHODS: Nationwide, population-based, matched cohort study of people with HIV (PWH) in Denmark between 1995 and 2021 who were matched on sex and date of birth with a comparison cohort randomly selected from the Danish population. Family-related factors were examined by inclusion of siblings of those in the cohorts. We calculated hazard ratios (HRs) for depression, receipt of antidepressants, electroconvulsive therapy (ECT), and suicide, as well as the yearly proportions of study cohorts with psychiatric hospital contact due to depression and receipt of antidepressants from 10 years before to 10 years after study inclusion. RESULTS: We included 5943 PWH and 59 430 comparison cohort members. Median age was 38 years, and 25% were women. We observed an increased risk of depression, receipt of antidepressants, ECT, and suicide among PWH in the 2 first years of observation (HR, 3.3; 95% confidence interval [CI]: 2.5-4.4), HR, 3.0 (95% CI: 2.7-3.4), HR, 2.8 (95% CI: .9-8.6), and HR, 10.7 (95% CI: 5.2-22.2), thereafter the risk subsided but remained increased. The proportions of PWH with psychiatric hospital contact due to depression and receipt of antidepressants were increased prior to and especially after HIV diagnosis. Risk of all outcomes was substantially lower among siblings of PWH than among PWH (HR for receipt of antidepressants, 1.1; 95% CI: 1.0-1.2). CONCLUSIONS: PWH have an increased risk of depression. Family-related factors are unlikely to explain this risk.

Long COVID (LC) is an emerging global health concern. The underlying mechanism and pathophysiology remain unclear. Presence of neutralizing autoantibodies against type 1 interferons (IFN) has been established as a predictor of critical COVID-19. We hypothesized that persistent autoimmune activity with autoantibodies against type 1 IFN may contribute to symptoms in patients with LC. Plasma samples and clinical information were obtained from a Danish LC cohort consisting of adult patients with confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Information on symptoms and quality of life was derived from an LC-specific questionnaire and the EQ-5D-5L questionnaire. Detection of type 1 IFN autoantibodies in plasma were performed by ELISA. Samples collected between June, 2020, and September, 2021, from 279 patients were analyzed and compared to a control group of 94 individuals with prior mild SARS-CoV-2 infection who did not develop LC symptoms. In total, five LC patients (1.8%) and 3 (3.2%) of the controls had detectable circulating type 1 IFN autoantibodies. Collectively, prevalence of autoantibodies against type 1 IFN subtypes in our LC cohort were primarily driven by men and did not exceed the prevalence in controls. Thus, in our cohort, anti-type I IFN autoantibodies are unlikely to drive LC symptoms.

UNLABELLED: Pharmacologically-induced activation of replication competent proviruses from latency in the presence of antiretroviral treatment (ART) has been proposed as a step towards curing HIV-1 infection. However, until now, approaches to reverse HIV-1 latency in humans have yielded mixed results. Here, we report a proof-of-concept phase Ib/IIa trial where 6 aviremic HIV-1 infected adults received intravenous 5 mg/m2 romidepsin (Celgene) once weekly for 3 weeks while maintaining ART. Lymphocyte histone H3 acetylation, a cellular measure of the pharmacodynamic response to romidepsin, increased rapidly (maximum fold range: 3.77.7 relative to baseline) within the first hours following each romidepsin administration. Concurrently, HIV-1 transcription quantified as copies of cell-associated un-spliced HIV-1 RNA increased significantly from baseline during treatment (range of fold-increase: 2.45.0; p = 0.03). Plasma HIV-1 RNA increased from <20 copies/mL at baseline to readily quantifiable levels at multiple post-infusion time-points in 5 of 6 patients (range 46103 copies/mL following the second infusion, p = 0.04). Importantly, romidepsin did not decrease the number of HIV-specific T cells or inhibit T cell cytokine production. Adverse events (all grade 12) were consistent with the known side effects of romidepsin. In conclusion, romidepsin safely induced HIV-1 transcription resulting in plasma HIV-1 RNA that was readily detected with standard commercial assays demonstrating that significant reversal of HIV-1 latency in vivo is possible without blunting T cell-mediated immune responses. These finding have major implications for future trials aiming to eradicate the HIV-1 reservoir. TRIAL REGISTRATION: clinicaltrials.gov NTC02092116.

BACKGROUND: Data on occurrence and risk factors for pneumocystis pneumonia (PCP) in patients with end-stage renal disease (ESRD) are sparse. METHODS: This was a nationwide population-based study assessing occurrence and risk factors for PCP among patients with ESRD and population controls over a 21-year period (1/1 1990 to 31/12 2010). Using Danish registry data, first-time diagnoses of PCP were identified. RESULTS: We identified 13 296 adult patients with ESRD and 244 255 controls, yielding 63 560 and 2 223 660 person-years of follow-up (PYFU), respectively. Fifty-eight first-time diagnoses of PCP were recorded in the ESRD group. Forty-six episodes occurred among renal transplant recipients (RTx) and 12 among haemodialysis patients (HD), yielding incidence rates of 181 (136-242) and 43.1 (24.5-75.9) per 100 000 PYFU. Compared to population controls, we found incidence rate-ratios of 125.9 (78.4-204) among RTx and 29.9 (14.1-59.7) among HD patients. Risk factors for PCP in RTx were age 50-65 years, age > 65 years, diabetes, polycystic kidney disease and hypertensive kidney disease/nephrosclerosis with an IRR of 2.22 (1.14-4.31), 3.12 (1.35-7.21), 3.44 (1.16-10.2), 4.25 (1.55-11.7) and 3.87 (1.49-10.0), respectively, and more than 36 months of dialysis before transplantation with an IRR of 1.99 (1.03-3.84). Among RTx the risk of PCP was highest during the first 6 months post-transplantation and increased from the beginning (IR1990-94 = 111 (46.3-267) per 100 000 PYFU) towards the end of the study period (IR2005-10 = 299 (203-439)). CONCLUSION: The PCP risk is substantial in RTx within the first 6 months of transplantation, emphasizing the potential benefit of prophylactic treatment in the early post-transplant period. Importantly, we identified subgroups within the RTx group that require more attention.

BACKGROUND: It is important to understand current trends in cancer risk among people living with HIV (PLWH) to improve outcomes and to commission and delivery appropriate services. METHODS: Nationwide, population-based, matched cohort study on all adult PLWH treated at Danish HIV health care centres since 1 January 1995 and a comparison cohort, randomly selected from the background population and matched on sex and date of birth. RESULTS: We included 6327 PLWH and 63,270 individuals in the comparison cohort - 74% were men and median age was 37 (interquartile range: 30-46). For both smoking related cancers, virological cancers and other cancers, incidence was substantially higher in the first year of observation for PLWH than for the remaining observation period. The risk of smoking related cancer remained stably increased throughout the observation period, whereas the relative risk of virological cancers decreased, especially in the first year of follow up. Finally, the risk of other cancers for PLWH decreased to a level below that of the background population during the study period. CONCLUSION: The fact that the risk of other cancers was probably not higher among PLWH than in the comparison cohort is encouraging, as the excess risk of virological and smoking related cancers is potentially preventable by timely treatment of HIV and smoking cessation.

Background: Survival among people with HIV (PWH) has vastly improved globally over the last few decades but remains lower than among the general population. We aimed to estimate time trends of survival among PWH and their families from 1995 to 2021. Methods: We conducted a registry-based, nationwide, population-based, matched cohort study. We included all Danish-born PWH from 1995 to 2021 who had been on antiretroviral therapy for 90 days, did not report intravenous drug use, and were not co-infected with hepatitis C (n = 4168). We matched population controls from the general population 10:1 to PWH by date of birth and sex (n = 41,680). For family cohorts, we identified siblings, mothers, and fathers of PWH and population controls. From Kaplan-Meier tables with age as time scale, we estimated survival from age 25. We compared PWH with population controls and families of PWH with families of population controls to calculate mortality rate ratios adjusted for sex, age, comorbidities, and education (aMRR). Findings: The median age of death among PWH increased from 27.5 years in 1995-1997 to 73.9 years (2010-2014), but thereafter survival increased only marginally. From 2015 to 2021, mortality was increased among PWH (aMRR 1.87 (95% CI: 1.65-2.11)) and siblings (aMRR: 1.25 (95% CI: 1.07-1.47)), mothers (aMRR: 1.30 (95% CI: 1.17-1.43)), and fathers (aMRR: 1.15 (95% CI: 1.03-1.29)) of PWH compared to their respective control cohorts. Mortality among siblings of PWH who reported heterosexual route of HIV transmission (aMRR: 1.51 (95% CI: 1.16-1.96)) was higher than for siblings of PWH who reported men who have sex with men as route of HIV transmission (aMRR 1.19 (95% CI: 0.98-1.46)). Interpretation: Survival among PWH improved substantially until 2010, after which it increased only marginally. This may partly be due to social and behavioural factors as PWH families also had higher mortality. Funding: Preben and Anna Simonsen's Foundation and Independent Research Fund Denmark.
RESUMO
Pulmonary alveolar proteinosis (PAP) is a rare lung disease characterized by accumulation of a periodic acid Schiff (PAS)-positive eosinophilic material in the distal airways. For decades, the standard treatment of PAP has been whole lung lavage (WLL), where large quantities of saline are instilled into the lungs to remove the proteinaceous material. However, not all patients respond to this treatment. Thus, new treatment modalities, such as subcutaneous or inhaled granulocyte macrophage colony-stimulating factor (GM-CSF), and the CD20 antibody rituximab and plasmapheresis, have been investigated. Based on the current literature, a stepwise treatment plan is suggested starting with WLL, continuing to inhaled GM-CSF, and then to rituximab if the former treatment regimes are unsuccessful.

BACKGROUND: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can replicate in the upper and lower respiratory tract. We aimed to evaluate whether symptom characteristics and symptom duration prior to sampling are associated with test positivity in upper or lower respiratory tract samples. METHODS: We conducted a retrospective cohort study in the Central Denmark Region from 14 April 2020 to 2 November 2020 including hospitalised patients with SARS-CoV-2 reverse transcriptase-polymerase chain reaction samples from both the upper and lower respiratory tract within 48 h and at least one positive test result. RESULTS: Of 122 patients, 101 were positive in both samples (83%), 7 (5%) were positive only in the upper respiratory tract sample, and 14 (11%) were only positive in the lower respiratory tract sample. The median number of symptoms was 4 (IQR 3, 5.75) and 5 (IQR 3, 7), respectively, in patients with only a positive upper respiratory tract sample and in concordant positive patients; while 1 (IQR 1, 3) in patients with only a positive upper respiratory tract sample. 98% (120/122) of patients would have been diagnosed with coronavirus disease 2019 if supplemental sampling from the lower respiratory tract was guided by lower respiratory tract symptoms. No substantial difference in the duration of symptoms was observed across the three patient groups. CONCLUSIONS: The presence of lower respiratory tract symptoms could have been used to determine whether supplemental sampling from the lower respiratory tract was necessary. Symptom duration was not associated with test positivity in the upper or lower respiratory tract.

A 45-year-old woman was admitted with severe pain in the right leg and dyspnea. Her medical history included previous Staphylococcus aureus endocarditis, biological aortic valve replacement, and intravenous drug abuse. She was febrile but did not have any focal signs of infection. Blood tests showed raised infectious markers and troponin levels. Electrocardiogram showed sinus rhythm without signs of ischemia. Ultrasound revealed thrombosis of the right popliteal artery. The leg was not critically ischemic, and therefore, treatment with dalteparin was chosen. Transesophageal echocardiography showed an excrescence on the biological aortic valve. Empiric treatment for endocarditis was started with intravenous vancomycin, gentamicin, and oral rifampicin. Blood cultures subsequently grew Staphylococcus pasteuri. On day 2, treatment was changed to intravenous cloxacillin. Due to the comorbidity, the patient was not a candidate for the surgical treatment. On day 10, the patient developed moderate expressive aphasia and weakness in the right upper limb. Magnetic resonance imaging showed micro-embolic lesions scattered across both hemispheres of the brain. Treatment was changed from cloxacillin to cefuroxime. On day 42, infectious markers were normal, and echocardiography showed regression of the excrescence. Antibiotic treatment was stopped. Follow-up on day 52 did not show any signs of active infection. However, on day 143, the patient was readmitted with cardiogenic shock due to aortic root fistulation to the left atrium. She quickly deteriorated and died.
RESUMO
Background: Post COVID-19 condition (PCC) is defined as symptoms lasting more than 12 weeks after developing COVID-19. Evidence of mitochondrial dysfunction has been reported in peripheral blood mononuclear cells obtained from patients with COVID-19. We hypothesized that PCC is caused by prolonged mitochondrial dysfunction. Given that coenzyme Q10 (CoQ10) can improve mitochondrial function, we examined whether high-dose CoQ10 can reduce the number and/or severity of PCC-related symptoms. Methods: In this placebo-controlled, double-blind, 2 × 2 crossover interventional trial, participants were recruited from two centres at Aarhus University Hospital and Gødstrup Hospital, Denmark. They were randomly assigned to receive either oral capsules of CoQ10 in a dose of 500 mg/day or placebo for 6 weeks, with crossover treatment after a 4-week washout period. The ED-5Q and a PCC-symptom specific questionnaire were completed by the participants at 5 visits during the 20-week study period. The primary endpoint was the change in the number and/or severity of PCC-related symptoms after the 6-week intervention compared to placebo. Participants who completed the two-dosing period were included in the primary analysis, while all participants receiving one dose were included in safety assessment. Findings: From May 25th, 2021, to September 22nd, 2021, 121 participants underwent randomization, and 119 completed both dosing periods - 59 and 60 in group A and B, respectively. At baseline, the mean PCC-related symptom score was 43.06 (95% CI: 40.18; 45.94), and the mean EQ-5D health index was 0.66 (95% CI: 0.64; 0.68). The difference between CoQ10 and placebo was not significant with respect to either the change in EQ-5D health index (with a mean difference of 0.01; 95% CI: -0.02; 0.04; p = 0.45) or the change in PCC-related symptom score (with a mean difference of -1.18; 95% CI: -3.54; 1.17; p = 0.32). Interpretation: Based on self-reported data, CoQ10 treatment does not appear to significantly reduce the number or severity of PCC-related symptoms when compared to placebo. However, we observed a significant spontaneous improvement on both scores regardless of treatment during 20 weeks observation. Funding: Placebo and CoQ10 capsules were provided by Pharma Nord, and the trial was supported by grants from the Novo Nordisk Foundation (NNF21OC0066984). This trial is registered with EudraCT, 2020-005961-16 and ClinicalTrials.gov, NCT04960215. The trial is completed.
RESUMO
OBJECTIVE: To compare the risk of a positive severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) test and coronavirus disease 2019 (COVID-19) outcomes in people with HIV (PWH) with the general population, and estimate the association with vaccination status. DESIGN: A nationwide, population based, matched cohort study. METHODS: We included all Danish PWH ≥18âyears ( n â=â5276) and an age and sex-matched general population cohort ( n â=â42 308). We used Cox regression analyses to calculate (adjusted) incidence rate ratios [(a)IRR] and further stratified and restricted the analyses. RESULTS: We observed no major difference in risk of first positive SARS-CoV-2 test [aIRR: 0.8 (95% confidence interval (CI): 0.8-0.9)], but a higher risk of first hospital contact with COVID-19 and hospitalization with severe COVID-19 for PWH vs. controls [IRR: 2.0; (1.6-2.5), 1.8 (1.4-2.3)]. Risk of first hospitalization decreased substantially in PWH with calendar time [first half of year 2022 vs. 2020 IRR: 0.3; (0.2-0.6)], whereas the risk compared to population controls remained almost twofold increased. We did not observe increased risk of death after SARS-CoV-2 infection [aIRR: 0.7 (95% CI: 0.3-2.0)]. Compared to PWH who had received two vaccines PWH who receiving a third vaccine had reduced risk of first positive SARS-CoV-2 test, death (individuals ≥60years) and hospitalization [aIRR: 0.9 (0.7-1.0); 0.2 (0.1-0.7); 0.6 (0.2-1.2)]. CONCLUSION: PWH have almost the same risk of a positive SARS-CoV-2 test as the general population. Although risk of hospital contacts and severe outcomes following SARS-CoV-2 infection is increased, the risk of death does not seem to be substantially increased. Importantly, a third vaccine is associated with reduced risk of infection, and death.

BACKGROUND AND OBJECTIVES: Epilepsy in patients with brain abscess is frequent, but risk factors and prognosis remain undetermined. This study examined risk factors of epilepsy among survivors of brain abscess and associated prognosis. METHODS: Nationwide, population-based healthcare registries were used to compute cumulative incidences and cause-specific adjusted hazard rate ratios (adj. HRRs) with 95% CIs for epilepsy among 30-day survivors of brain abscess from 1982 through 2016. Data were enriched with clinical details by medical record review of patients hospitalized from 2007 through 2016. Adjusted mortality rate ratios (adj. MRRs) were examined using epilepsy as a time-dependent variable. RESULTS: The study included 1,179 30-day survivors of brain abscess among whom 323 (27%) developed new-onset epilepsy after a median of 0.76 years (interquartile range [IQR] 0.24-2.41). At admission for brain abscess, the median age was 46 years (IQR 32-59) in patients with epilepsy compared with 52 years (IQR 33-64) in those without epilepsy. The proportion of female individuals was similar in patients with and without epilepsy (37%). Adj. HRRs for epilepsy were 2.44 (95% CI 1.89-3.15) for aspiration or excision of brain abscess, 2.37 (1.56-3.60) for alcohol abuse, 1.75 (1.27-2.40) for previous neurosurgery or head trauma, 1.62 (1.17-2.25) for stroke, and 1.55 (1.04-2.32) for age group 20-39 years. Cumulative incidences were increased in patients with alcohol abuse (52% vs 31%), aspiration or excision of brain abscess (41% vs 20%), previous neurosurgery or head trauma (41% vs 31%), and stroke (46% vs 31%). Analysis using clinical details from medical record review of patients from 2007 through 2016 demonstrated adj. HRRs of 3.70 (2.24-6.13) for seizures at admission for brain abscess and 1.80 (1.04-3.11) for frontal lobe abscess. By contrast, adj. HRR was 0.42 (0.21-0.86) for occipital lobe abscess. Using the entire registry-based cohort, patients with epilepsy had an adj. MRR of 1.26 (1.01-1.57). DISCUSSION: Important risk factors of epilepsy were seizures during admission for brain abscess, neurosurgery, alcoholism, frontal lobe abscess, and stroke. Epilepsy was associated with an increased mortality. Antiepileptic treatment may be guided by individual risk profiles, and a specialized follow-up is highlighted by an increased mortality in survivors with epilepsy.

OBJECTIVES: Persistent symptoms on short-term follow-up after infection with COVID-19 are common, but long-term consequences have been insufficiently studied. The aim of this study was to characterize pulmonary function and ongoing symptoms 12 months after hospitalization with COVID-19. METHODS: This prospective multicenter study included 222 patients hospitalized with PCR-confirmed COVID-19 in the Central Denmark Region. Disease severity was stratified using WHO Clinical Progression Scale. Clinical characteristics, pulmonary function test (PFT), 6-minute walk test (6MWT), and patient-reported outcome measures were collected at follow-up 3 and 12 months after discharge. Outcome measures from follow-up 3 months after discharge have previously been published. RESULTS: A total of 179 (81%) patients completed the 12-month follow-up. Median age was 60 years (IQR 51, 69) and 58% were male patients. At 12-month follow-up 49.7% had a normal diffusion capacity for carbon monoxide (DLCO), while 39.4% had DLCO < 80%. The 6MWT distance increased significantly (29 m 95% CI 19, 40; p < 0.01). An mMRC score of 0 was reported by 51% and an mMRC ≥ 2 by 20%. The frequency and severity of fatigue, depression, and anxiety did not improve over time. CONCLUSIONS: The study found that impaired DLCO percentage is common 12 months after hospitalization with SARS-CoV-2 and reduction in DLCO percentage is associated to dyspnea.

Inducing antiretroviral therapy (ART)-free virological control is a critical step toward a human immunodeficiency virus type 1 (HIV-1) cure. In this phase 2a, placebo-controlled, double-blinded trial, 43 people (85% males) with HIV-1 on ART were randomized to (1) placebo/placebo, (2) lefitolimod (TLR9 agonist)/placebo, (3) placebo/broadly neutralizing anti-HIV-1 antibodies (bNAbs) or (4) lefitolimod/bNAb. ART interruption (ATI) started at week 3. Lefitolimod was administered once weekly for the first 8 weeks, and bNAbs were administered twice, 1 d before and 3 weeks after ATI. The primary endpoint was time to loss of virologic control after ATI. The median delay in time to loss of virologic control compared to the placebo/placebo group was 0.5 weeks (P = 0.49), 12.5 weeks (P = 0.003) and 9.5 weeks (P = 0.004) in the lefitolimod/placebo, placebo/bNAb and lefitolimod/bNAb groups, respectively. Among secondary endpoints, viral doubling time was slower for bNAb groups compared to non-bNAb groups, and the interventions were overall safe. We observed no added benefit of lefitolimod. Despite subtherapeutic plasma bNAb levels, 36% (4/11) in the placebo/bNAb group compared to 0% (0/10) in the placebo/placebo group maintained virologic control after the 25-week ATI. Although immunotherapy with lefitolimod did not lead to ART-free HIV-1 control, bNAbs may be important components in future HIV-1 curative strategies. ClinicalTrials.gov identifier: NCT03837756 .

Minimal hepatic encephalopathy (MHE) is a metabolic brain disorder occurring in patients with liver cirrhosis. MHE lessens a patient's quality of life, but is treatable when identified. The continuous reaction times (CRT) method is used in screening for MHE. Gender and age effects on the CRT method are unknown and may confound the results. The aim of this study was to standardise the CRT method outcomes for age and gender effects. We studied 121 volunteers without known disease and 181 patients with cirrhosis by a CRT test. Reaction time to an auditory signal was measured 100 times, the 10th, 50th, and 90th reaction time percentiles were recorded, and the CRT index was calculated as the 50th percentile/(90th percentile-10th percentile), as a measure of intra-individual stability in reaction times. In volunteers, men reacted faster than women and their reaction times slowed with age. However, neither the gender nor the age effect was present regarding the CRT index. The patients with cirrhosis reacted slower and with a higher degree of instability than volunteers. Male patients reacted faster than female patients, and reaction times tended to slow with age. As among the volunteers, there was no gender or age effect on CRT index for the patients with cirrhosis. Age and gender influenced reaction times of both volunteers and patients with cirrhosis. The CRT index, however, was independent of age and gender in both groups. Screening of patients with cirrhosis using the CRT index, therefore, identifies brain dysfunction rather than effects of gender and age.

Studies suggest that persistent symptoms after COVID-19 (long COVID) influence functioning and activities of daily living (ADL). However, it is still uncertain how and to what extent. This study aimed to describe patient-reported mental fatigue, ADL problems, ADL ability, sick leave and functional status among patients with long COVID. In this cross-sectional study, 448 patients, ≥18 years old and referred to occupational therapy at a Danish Post-COVID-19 Clinic, were included. Mental fatigue was measured by the Mental Fatigue Scale, ADL problems and ability were measured by the Canadian Occupational Performance Measure, sick leave was self-reported and functional status was evaluated by the Post-COVID-19 Functional Status Scale. Mean age was 46.8 years, 73% of the patients were female, and 75% suffered from moderate to severe mental fatigue. The majority reported difficulties performing productive and leisure activities. The median performance and satisfaction scores were 4.8 and 3, respectively. In total, 56% of the patients were on sick leave, and 94% were referred to rehabilitation. A decrease in functional status was found between pre-COVID-19 and assessment. Conclusively, the patients were highly affected in their everyday life and had distinct rehabilitation needs. Future research is needed to address causalities and rehabilitation for this patient group.

Aims: Persistent cardiac symptoms are an increasingly reported phenomenon following COVID-19. However, the underlying cause of cardiac symptoms is unknown. This study aimed to identify the underlying causes, if any, of these symptoms 1 year following acute COVID-19 infection. Methods and Results: 22 individuals with persistent cardiac symptoms were prospectively investigated using echocardiography, cardiovascular magnetic resonance (CMR), 6-min walking test, cardio-pulmonary exercise testing and electrocardiography. A median of 382 days (IQR 368, 442) passed between diagnosis of COVID-19 and investigation. As a cohort their echocardiography, CMR, 6-min walking test and exercise testing results were within the normal ranges. There were no differences in left ventricular ejection fraction (61.45 ± 6.59 %), global longitudinal strain (19.80 ± 3.12 %) or tricuspid annular plane systolic excursion (24.96 ± 5.55 mm) as measured by echocardiography compared to a healthy control group. VO2 max (2045.00 ± 658.40 ml/min), % expected VO2 max (114.80 ± 23.08 %) and 6-minute distance walked (608.90 ± 54.51 m) exceeded that expected for the patient cohort, whilst Troponin I (5.59 ± 6.59 ng/l) and Nt-proBNP (88.18 ± 54.27 ng/l) were normal. Conclusion: Among a cohort of 22 patients with self-reported persistent cardiac symptoms, we identified no underlying cardiac disease or reduced cardiopulmonary fitness 1 year following COVID-19.
RESUMO
Persistent symptoms after hospitalization with COVID-19 are common, but the frequency and severity of these symptoms are insufficiently understood. We aimed to describe symptoms and pulmonary function after hospitalization with COVID-19. Patients hospitalized with COVID-19 in Central Denmark Region were invited for follow-up 3 months after discharge. Clinical characteristics, patient reported outcomes (Fatigue Assessment Scale (FAS), anxiety and depression (HADS)), symptoms, pulmonary function test and 6-min walk test were collected. We included 218 patients (mean age 59.9 (95% CI: 58.2, 61.7), 59% males). Fatigue, dyspnea and impaired concentration were the most prevalent symptoms at follow-up. Using FAS, 47% reported mild-to-moderate fatigue and 18% severe fatigue. Mean HADS was 7.9 (95% CI: 6.9, 8.9). FAS was correlated to HADS (ß = 0.52 (95% CI: 0.44, 0.59, p < 0.001)). Mean DLCO was 80.4% (95% CI: 77.8, 83.0) and 45% had DLCO Ë 80%. Mean DLCO was significantly reduced in patients treated in the ICU (70.46% (95% CI 65.13, 75.79)). The highest FAS and HADS were seen in patients with the shortest period of hospitalization (2.1 days (95% CI: 1.4, 2.7)) with no need for oxygen. In conclusion, fatigue is a common symptom after hospitalization for COVID-19 and ICU treatment is associated to decreased diffusion capacity.
RESUMO
PURPOSE: To examine the positive predictive value (PPV) of International Classification version 10 (ICD-10) diagnosis codes for Coronavirus disease 2019 (COVID-19). PATIENTS AND METHODS: Medical record review of all patients assigned a diagnosis code of COVID-19 (DB342A or DB972A) at six Danish departments of infectious diseases from February 27 through May 4, 2020. Confirmed COVID-19 diagnosis was defined as either: 1) definite, a positive polymerase chain reaction (PCR) for severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2) on a respiratory sample combined with symptoms suggestive of COVID-19: 2) probable, clinical presentation of COVID-19 without detection of SARS-CoV-2 and no alternative diagnoses considered more likely; or 3) possible, clinical presentation of COVID-19 without detection of SARS-CoV-2, and the patient was discharged or deceased before further investigations were carried out. We computed the PPV with 95% confidence intervals (CI) as the number of patients with confirmed (i.e., definite, probable, and possible) COVID-19 divided by the number of patients assigned a diagnosis code for COVID-19. RESULTS: The study included 710 patients with a median age of 61 years (interquartile range [IQR] 47-74) and 285/710 (40%) were female. COVID-19 was confirmed in 706/710 (99%) with 705/710 (99%) categorized as definite, 1/710 (0.1%) as probable, and 0 patients as possible COVID-19. The diagnosis was disproven in 4/710 (0.6%) patients who were hospitalized due to bacterial pneumonia (n = 2), influenza (n = 1), and urinary tract infection (n = 1). The overall PPV for COVID-19 was 99% (95% CI 99-100) and remained consistently high among all subgroups including sex, age groups, calendar period, and stratified by diagnosis code and department of infectious diseases (range 97-100%). CONCLUSION: The overall PPV of diagnosis codes for COVID-19 in Denmark was high and may be suitable for future registry-based prognosis studies of COVID-19.
