Abstract
INTRODUCTION The multiorgan impact of moderate to severe coronavirus infections in the post-acute phase is still poorly understood. We aimed to evaluate the excess burden of multiorgan abnormalities after hospitalisation with COVID-19, evaluate their determinants, and explore associations with patient-related outcome measures. METHODS In a prospective, UK-wide, multicentre MRI follow-up study (C-MORE), adults (aged ≥18 years) discharged from hospital following COVID-19 who were included in Tier 2 of the Post-hospitalisation COVID-19 study (PHOSP-COVID) and contemporary controls with no evidence of previous COVID-19 (SARS-CoV-2 nucleocapsid antibody negative) underwent multiorgan MRI (lungs, heart, brain, liver, and kidneys) with quantitative and qualitative assessment of images and clinical adjudication when relevant. Individuals with end-stage renal failure or contraindications to MRI were excluded. Participants also underwent detailed recording of symptoms, and physiological and biochemical tests. The primary outcome was the excess burden of multiorgan abnormalities (two or more organs) relative to controls, with further adjustments for potential confounders. The C-MORE study is ongoing and is registered with ClinicalTrials.gov, NCT04510025. FINDINGS Of 2710 participants in Tier 2 of PHOSP-COVID, 531 were recruited across 13 UK-wide C-MORE sites. After exclusions, 259 C-MORE patients (mean age 57 years [SD 12]; 158 [61%] male and 101 [39%] female) who were discharged from hospital with PCR-confirmed or clinically diagnosed COVID-19 between March 1, 2020, and Nov 1, 2021, and 52 non-COVID-19 controls from the community (mean age 49 years [SD 14]; 30 [58%] male and 22 [42%] female) were included in the analysis. Patients were assessed at a median of 5·0 months (IQR 4·2-6·3) after hospital discharge. Compared with non-COVID-19 controls, patients were older, living with more obesity, and had more comorbidities. Multiorgan abnormalities on MRI were more frequent in patients than in controls (157 [61%] of 259 vs 14 [27%] of 52; p<0·0001) and independently associated with COVID-19 status (odds ratio [OR] 2·9 [95% CI 1·5-5·8]; padjusted=0·0023) after adjusting for relevant confounders. Compared with controls, patients were more likely to have MRI evidence of lung abnormalities (p=0·0001; parenchymal abnormalities), brain abnormalities (p<0·0001; more white matter hyperintensities and regional brain volume reduction), and kidney abnormalities (p=0·014; lower medullary T1 and loss of corticomedullary differentiation), whereas cardiac and liver MRI abnormalities were similar between patients and controls. Patients with multiorgan abnormalities were older (difference in mean age 7 years [95% CI 4-10]; mean age of 59·8 years [SD 11·7] with multiorgan abnormalities vs mean age of 52·8 years [11·9] without multiorgan abnormalities; p<0·0001), more likely to have three or more comorbidities (OR 2·47 [1·32-4·82]; padjusted=0·0059), and more likely to have a more severe acute infection (acute CRP >5mg/L, OR 3·55 [1·23-11·88]; padjusted=0·025) than those without multiorgan abnormalities. Presence of lung MRI abnormalities was associated with a two-fold higher risk of chest tightness, and multiorgan MRI abnormalities were associated with severe and very severe persistent physical and mental health impairment (PHOSP-COVID symptom clusters) after hospitalisation. INTERPRETATION After hospitalisation for COVID-19, people are at risk of multiorgan abnormalities in the medium term. Our findings emphasise the need for proactive multidisciplinary care pathways, with the potential for imaging to guide surveillance frequency and therapeutic stratification.

Abstract
Abstract
Purpose
Advances in the management of severe, eosinophilic asthma have improved, but asthma exacerbations continue to occur. This review aims to look at the evidence we have about why exacerbations may occur; their phenotype and why oral corticosteroids may not always be the best treatment option for all exacerbation of symptoms in individuals with severe asthma.
Recent findings
Studies dating back to the 1990s showed that asthma exacerbations across the spectrum of asthma severity were of different inflammatory endotypes. In addition, there is a wealth of evidence suggesting that eosinophilic inflammation is very responsive to corticosteroid therapy, but that non-eosinophilic inflammation is less so. Two recent UK-based studies have undertaken systematic phenotyping of exacerbations in severe asthma and have shown that there are a significant minority of exacerbation events with an increase in asthma symptoms, fall in lung function, but without evidence of raised T2 biomarkers.
Summary
The evidence to date would suggest that T2 biomarker low asthma exacerbations do not benefit from the administration of oral corticosteroids; in fact, the effect of the oral corticosteroids is harmful. However, there is a paucity of data to answer this question directly. Further research is needed to assess the evolution of non-T2 exacerbations not treated with OCS in a randomised, placebo-controlled, manner.

Abstract
BACKGROUND Approximately 5-10% of patients with asthma have severe disease with a consistent preponderance in females. Current asthma guidelines recommend stepwise treatment to achieve symptom control with no differential treatment considerations for either sex. OBJECTIVES To examine whether patient sex affects outcomes when using a composite T2-biomarker score to adjust corticosteroid treatment in patients with severe asthma compared to standard care. METHODS Post-hoc analysis stratifying patient outcomes by sex of a 48-week, multicentre, randomised controlled clinical trial comparing a biomarker-defined treatment algorithm with standard care. The primary outcome was the proportion of patients with a reduction in corticosteroid treatment (inhaled (ICS) and oral (OCS) corticosteroids). Secondary outcomes included exacerbation rates, hospital admissions and lung function. RESULTS Of 301 patients randomised; 194 (64.5%) were females and 107 (35.5%) were males. The biomarker algorithm led to a greater proportion of females being on a lower corticosteroid dose vs standard care which was not seen in males (effects estimate females: 3.57, 95% CI: 1.14, 11.18 vs. males 0.54, 95% CI: 0.16, 1.80). In T2-biomarker low females, reducing corticosteroid dose was not associated with increased exacerbations. Females scored higher in all ACQ-7 domains, but with no difference when adjusted for BMI/ anxiety and/or depression. Dissociation between symptoms and T2-biomarkers were noted in both sexes, with a higher proportion of females being symptom high/T2-biomarker low (22.8% vs. 15.6%; p=0.0002), whereas males were symptom low/T2-biomarker high (11.4% vs. 22.3%; p<0.0001). CONCLUSION This exploratory post-hoc analysis identified females achieved a greater benefit from biomarker-directed corticosteroid optimisation versus symptom-directed treatment.

Abstract
BACKGROUND No effective pharmacological or non-pharmacological interventions exist for patients with long COVID. We aimed to describe recovery 1 year after hospital discharge for COVID-19, identify factors associated with patient-perceived recovery, and identify potential therapeutic targets by describing the underlying inflammatory profiles of the previously described recovery clusters at 5 months after hospital discharge. METHODS The Post-hospitalisation COVID-19 study (PHOSP-COVID) is a prospective, longitudinal cohort study recruiting adults (aged ≥18 years) discharged from hospital with COVID-19 across the UK. Recovery was assessed using patient-reported outcome measures, physical performance, and organ function at 5 months and 1 year after hospital discharge, and stratified by both patient-perceived recovery and recovery cluster. Hierarchical logistic regression modelling was performed for patient-perceived recovery at 1 year. Cluster analysis was done using the clustering large applications k-medoids approach using clinical outcomes at 5 months. Inflammatory protein profiling was analysed from plasma at the 5-month visit. This study is registered on the ISRCTN Registry, ISRCTN10980107, and recruitment is ongoing. FINDINGS 2320 participants discharged from hospital between March 7, 2020, and April 18, 2021, were assessed at 5 months after discharge and 807 (32·7%) participants completed both the 5-month and 1-year visits. 279 (35·6%) of these 807 patients were women and 505 (64·4%) were men, with a mean age of 58·7 (SD 12·5) years, and 224 (27·8%) had received invasive mechanical ventilation (WHO class 7-9). The proportion of patients reporting full recovery was unchanged between 5 months (501 [25·5%] of 1965) and 1 year (232 [28·9%] of 804). Factors associated with being less likely to report full recovery at 1 year were female sex (odds ratio 0·68 [95% CI 0·46-0·99]), obesity (0·50 [0·34-0·74]) and invasive mechanical ventilation (0·42 [0·23-0·76]). Cluster analysis (n=1636) corroborated the previously reported four clusters: very severe, severe, moderate with cognitive impairment, and mild, relating to the severity of physical health, mental health, and cognitive impairment at 5 months. We found increased inflammatory mediators of tissue damage and repair in both the very severe and the moderate with cognitive impairment clusters compared with the mild cluster, including IL-6 concentration, which was increased in both comparisons (n=626 participants). We found a substantial deficit in median EQ-5D-5L utility index from before COVID-19 (retrospective assessment; 0·88 [IQR 0·74-1·00]), at 5 months (0·74 [0·64-0·88]) to 1 year (0·75 [0·62-0·88]), with minimal improvements across all outcome measures at 1 year after discharge in the whole cohort and within each of the four clusters. INTERPRETATION The sequelae of a hospital admission with COVID-19 were substantial 1 year after discharge across a range of health domains, with the minority in our cohort feeling fully recovered. Patient-perceived health-related quality of life was reduced at 1 year compared with before hospital admission. Systematic inflammation and obesity are potential treatable traits that warrant further investigation in clinical trials.

Abstract
BACKGROUND Angiotensin receptor blockers (ARBs; including candesartan, losartan, olmesartan and valsartan) are widely used to treat hypertension, heart failure and diabetic neuropathy. There is considerable pre-clinical evidence that ARBs can reduce cancer progression, particularly for gastric cancer. Despite this, epidemiological studies have yet to assess the impact of ARB use on gastro-oesophageal cancer survival. AIM To investigate the association between post-diagnosis ARB use and gastro-oesophageal cancer survival. METHODS We selected a cohort of patients with newly-diagnosed gastro-oesophageal cancer between 1998 and 2012 from English cancer registries. We linked to prescription and clinical records from the Clinical Practice Research Datalink, and to death records from the Office for National Statistics. We used time-dependant Cox-regression models to calculate hazard ratios (HRs) comparing gastro-oesophageal cancer-specific mortality between post-diagnosis ARB users and non-users, after adjusting for demographics, comorbidities and post-diagnosis aspirin or statin use. RESULTS Our cohort included 5124 gastro-oesophageal cancer patients, of which 360 used ARBs, and 3345 died due to their gastro-oesophageal cancer during follow-up. After adjustment, ARB users had moderately lower risk of gastro-oesophageal cancer mortality than the non-users (HR = 0.83, 95% CI 0.71-0.98). There was evidence of a dose-response relationship with the lowest HRs observed among patients receiving at least 2 years of prescriptions (HR = 0.42, 95% CI 0.25-0.72). CONCLUSIONS In this large population-based gastro-oesophageal cancer cohort, we found moderately reduced cancer-specific mortality among ARB users. However, confirmation in further independent epidemiological studies with sufficient staging information is required.

Abstract
Background Previously, we identified three loci affecting HDL-cholesterol levels in a screen for ENU-induced mutations in mice and discovered two mutated genes. We sought to identify the third mutated gene and further characterize the mouse phenotype. Methods We engaged, DNA sequencing, gene expression profiling, western blotting, lipoprotein characterization, metabolomics assessment, histology and electron microscopy in mouse tissues. Results We identify the third gene as Ampd2, a liver isoform of AMP Deaminase (Ampd), a central component of energy and purine metabolism pathways. The causative mutation was a guanine-to-thymine transversion resulting in an A341S conversion in Ampd2. Ampd2 homozygous mutant mice exhibit a labile hypercholesterolemia phenotype, peaking around 9 weeks of age (251 mg/dL vs. wildtype control at 138 mg/dL), and was evidenced by marked increases in HDL, VLDL and LDL. In an attempt to determine the molecular connection between Ampd2 dysfunction and hypercholesterolemia, we analyzed hepatic gene expression and found the downregulation of Ldlr, Hmgcs and Insig1 and upregulation of Cyp7A1 genes. Metabolomic analysis confirmed an increase in hepatic AMP levels and a decrease in allantoin levels consistent with Ampd2 deficiency, and increases in campesterol and β-sitosterol. Additionally, nephrotic syndrome was observed in the mutant mice, through proteinuria, kidney histology and effacement and blebbing of podocyte foot processes by electron microscopy. Conclusion In summary we describe the discovery of a novel genetic mouse model of combined transient nephrotic syndrome and hypercholesterolemia, resembling the human disorder.

Abstract
BACKGROUND As a result of long delays for physiotherapy for musculoskeletal problems, several areas in the UK have introduced PhysioDirect services in which patients telephone a physiotherapist for initial assessment and treatment advice. However, there is no robust evidence about the effectiveness, cost-effectiveness or acceptability to patients of PhysioDirect. OBJECTIVE To investigate whether or not PhysioDirect is equally as clinically effective as and more cost-effective than usual care for patients with musculoskeletal (MSK) problems in primary care. DESIGN Pragmatic randomised controlled trial to assess equivalence, incorporating economic evaluation and nested qualitative research. Patients were randomised in 2 : 1 ratio to PhysioDirect or usual care using a remote automated allocation system at the level of the individual, stratifying by physiotherapy site and minimising by sex, age group and site of MSK problem. For the economic analysis, cost consequences included NHS and patient costs, and the cost of lost production. Cost-effectiveness analysis was carried out from the perspective of the NHS. Interviews were conducted with patients, physiotherapists and their managers. SETTING Four community physiotherapy services in England. PARTICIPANTS Adults referred by general practitioners or self-referred for physiotherapy for a MSK problem. INTERVENTIONS Patients allocated to PhysioDirect were invited to telephone a senior physiotherapist for initial assessment and advice using a computerised template, followed by face-to-face care when necessary. Patients allocated to usual care were put on to a waiting list for face-to-face care. MAIN OUTCOME MEASURES Primary outcome was the Short Form questionnaire-36 items, version 2 (SF-36v2) Physical Component Score (PCS) at 6 months after randomisation. Secondary outcomes included other measures of health outcome [Measure Yourself Medical Outcomes Profile, European Quality of Life-5 Dimensions (EuroQol health utility measure, EQ-5D), global improvement, response to treatment], wait for treatment, time lost from work and usual activities, patient satisfaction. Data were collected by postal questionnaires at baseline, 6 weeks and 6 months, and from routine records by researchers blind to allocation. RESULTS A total of 1506 patients were allocated to PhysioDirect and 743 to usual care. Patients allocated to PhysioDirect had a shorter wait for treatment than those allocated to usual care [median 7 days vs 34 days; arm-time ratio 0.32, 95% confidence interval (CI) 0.29 to 0.35] and had fewer non-attended face-to-face appointments [incidence rate ratio 0.55 (95% CI 0.41 to 0.73)]. The primary outcome at 6 months' follow-up was equivalent between PhysioDirect and usual care [mean PCS 43.50 vs 44.18, adjusted difference in means -0.01 (95% CI -0.80 to 0.79)]. The secondary measures of health outcome all demonstrated equivalence at 6 months, with slightly greater improvement in the PhysioDirect arm at 6 weeks' follow-up. Patients were equally satisfied with access to care but slightly less satisfied overall with PhysioDirect compared with usual care. NHS costs (physiotherapy plus other relevant NHS costs) per patient were similar in the two arms [PhysioDirect £ 198.98 vs usual care £ 179.68, difference in means £ 19.30 (95% CI -£ 37.60 to £ 76.19)], while QALYs gained were also similar [difference in means 0.007 (95% CI -0.003 to 0.016)]. Incremental cost per QALY gained was £ 2889. The probability that PhysioDirect was cost-effective at a £ 20,000 willingness-to-pay threshold was 88%. These conclusions about cost-effectiveness were robust to sensitivity analyses. There was no evidence of difference between trial arms in cost to patients or value of lost production. No adverse events were detected. CONCLUSIONS Providing physiotherapy via PhysioDirect is equally clinically effective compared with usual waiting list-based care, provides faster access to treatment, appears to be safe, and is broadly acceptable to patients. PhysioDirect is probably cost-effective compared with usual care.

Abstract
Recombinant fibroblast growth factor (FGF)21 has antihyperglycemic, antihyperlipidemic, and antiobesity effects in diabetic rodent and monkey models. Previous studies were confined to measuring steady-state effects of FGF21 following subchronic or chronic administration. The present study focuses on the kinetics of biological actions of FGF21 following a single injection and on the associated physiological and cellular mechanisms underlying FGF21 actions. We show that FGF21 resulted in rapid decline of blood glucose levels and immediate improvement of glucose tolerance and insulin sensitivity in two animal models of insulin resistance (ob/ob and DIO mice). In ob/ob mice, FGF21 led to a 40-60% decrease in blood glucose, insulin, and amylin levels within 1 h after injection, and the maximal effects were sustained for more than 6 h despite the 1- to 2-h half-life of FGF21. In DIO mice, FGF21 reduced fasting blood glucose and insulin levels and improved glucose tolerance and insulin sensitivity within 3 h of treatment. The acute improvement of glucose metabolism was associated with a 30% reduction of hepatic glucose production and an increase in peripheral glucose turnover. FGF21 appeared to have no direct effect on ex vivo pancreatic islet insulin or glucagon secretion. However, it rapidly induced typical FGF signaling in liver and adipose tissues and in several hepatoma-derived cell lines and differentiated adipocytes. FGF21 was able to inhibit glucose release from H4IIE hepatoma cells and stimulate glucose uptake in 3T3-L1 adipocytes. We conclude that the acute glucose-lowering and insulin-sensitizing effects of FGF21 are potentially associated with its metabolic actions in liver and adipose tissues.

Abstract
Although pulmonary rehabilitation results in improvement in multiple outcome areas, relatively few studies in the United States have evaluated its effect on healthcare utilization. This study compared aspects of healthcare utilization during the year before to the year after outpatient pulmonary rehabilitation in patients with chronic obstructive pulmonary disease referred to 11 hospital-based centers in Connecticut and New York. Utilization data from 128 of 132 patients who originally gave informed consent were evaluated; their mean age was 69 years and their forced expiratory volume in 1 second was 44% of predicted. Forty-five percent had 1 or more hospitalizations in the year before beginning pulmonary rehabilitation. In the year after pulmonary rehabilitation, there were 0.25 fewer total hospitalizations (P = .017) and 2.18 fewer hospital days (P = .015) per patient and 271 fewer hospital days for the group. Hospitalizations for respiratory reasons also decreased significantly. Most of the reduction in hospital utilization was due to a decrease in intensive care unit days. The number of physician visits decreased by 2.4 in the year after pulmonary rehabilitation (P < .0001); most of this reduction was due to decreased visits to primary care providers. The estimated costs/charges for the aspects of healthcare utilization that we studied decreased by a mean of 4,694 dollars and a median of 390 dollars (P = .0002). This study suggests that pulmonary rehabilitation leads to a reduction in healthcare utilization.

Abstract
The extracellular Ca2+ (Ca(0)2+)-sensing receptor (CaR) recently cloned from mammalian parathyroid, kidney, brain, and thyroid plays a central role in maintaining near constancy of Ca(0)2+. We previously showed that the hypercalcemia normally present in New Zealand white rabbits is associated with an elevated set point for Ca(02+)-regulated PTH release (the level of Ca(0)2+ half-maximally inhibiting hormonal secretion). This observation suggested an alteration in the Ca(02+)-sensing mechanism in the rabbit parathyroid, a possibility we have now pursued by isolating and characterizing the rabbit homolog of the CaR. The cloned rabbit kidney CaR (RabCaR) shares a high degree of overall homology (> 90% amino acid identity) with the bovine, human, and rat CaRs, although it differs slightly in several regions of the extracellular domain potentially involved in binding ligands. By Northern analysis and/or immunohistochemistry, a similar or identical receptor is also expressed in parathyroid, thyroid C cells, small and large intestine, and in the thick ascending limb and collecting ducts of the kidney. When expressed transiently in HEK293 cells and assayed functionally through CaR agonist-evoked increases in Ca(i)2+, the rabbit CaR shows apparent affinities for Ca(0)2+, Mg(0)2+, and Gd(0)3+ that are indistinguishable from those observed in studies carried out concomitantly using the human CaR. Therefore, at least as assessed by its ability to increase Ca(i)2+ when expressed in HEK293 cells, the intrinsic functional properties of the rabbit CaR cannot explain the hypercalcemia observed in vivo in the New Zealand white rabbit.

Abstract
Osteoarthritis is the most ubiquitous rheumatic disease worldwide. Although its prevalence in various populations has been well documented, few studies have evaluated the longitudinal radiographic progression of the disease, especially as it is expressed in the interphalangeal joints of the hand. In this longitudinal study, left hand-wrist X-rays of 386 white male participants of the Baltimore Longitudinal Study of Aging followed for at least 5 years with two or more visits were examined for prevalence and progression of osteoarthritis of the distal and proximal interphalangeal joints of the hand. As other studies have shown, we found that the prevalence of osteoarthritis in both distal and proximal interphalangeal joints becomes progressively higher as the age of the subjects increases. Using the life table method of analysis we studied the progression of osteoarthritis as defined by the following criteria: (1) an increase in the severity of radiographic changes of the joints previously affected and (2) an increase in the number of new joints affected. The results indicated that osteoarthritis in both the distal and proximal interphalangeal joints progresses at a faster rate in the older population than in individuals less than 60 years of age. Furthermore, osteoarthritis in the interphalangeal joints progresses at the same rate whether the starting point was a Kellgren grade of 0 (no disease) or 1 (doubtful). We therefore conclude that grade 1 is an intermediate step in the inexorable progression of osteoarthritis of the interphalangeal joints and not synonymous with grade 0, as it has been customarily interpreted.

Abstract
Fifty healthy women between the ages of 40 and 65 participated in a 12-week program of exercise, discussion sessions, or both. Levels of serum cholesterol, triglycerides, total high-density lipoprotein (HDL), HDL-cholesterol, and HDL-2b were monitored at baseline and at six and 12 weeks. Cardiorespiratory function was assessed at baseline and 12 weeks. Women participating in the exercise groups had smaller increases in serum cholesterol (P less than .05) and greater increases in maximal oxygen consumption, time spent on a treadmill, and time required to attain 90% of maximal oxygen consumption (P less than .01) than the nonexercising women. No statistically significant differences were observed in levels of serum triglycerides, total HDL, or HDL-cholesterol fractions between nonexercising and exercising groups at either six or 12 weeks.

Abstract
Many changes occur in the immune system with age. The involution of the thymus plays a major role in immune senescence. Related to this event are the altered ratio of helper to suppressor T-lymphocyte subsets, decrease in immune response by both cell-mediated and humoral branches of the immune system, and increase in autoimmune activity. The clinical implications of these changes are the elderly person's increased susceptibility to infections such as pneumococcal pneumonia, influenza A, and tetanus as well as increased autoimmune activity, reflected by pernicious anemia. Other changes may be increased susceptibility to neoplasms and perhaps acceleration of the aging process. A high index of suspicion should be present for the diagnosis of pernicious anemia in the elderly population. Knowledge of the many autoantibodies that might be present without illness is important when evaluating for disease processes. The relationship of the senescent immune system to the aging process is still unknown. Investigations of this matter, as well as of the function of immune system components and their relationship to disease processes, are continuing. Most methods proposed for enhancing the immune system are still experimental. However, immunizations have been proved to be an effective means of reducing morbidity and mortality from certain infectious diseases in the elderly. Therefore, it is strongly recommended that all elderly persons who are at risk for pneumococcal pneumonia, influenza, and tetanus receive the proper immunizations.
