Abstract
BACKGROUND Older adults, particularly in long-term care facilities (LTCF), remain at considerable risk from SARS-CoV-2. Data on the protective effect and mechanisms of hybrid immunity are skewed towards young adults precluding targeted vaccination strategies. METHODS A single-centre longitudinal seroprevalence vaccine response study was conducted with 280 LCTF participants (median 82 yrs, IQR 76-88 yrs; 95.4% male). Screening by SARS-CoV-2 polymerase chain reaction with weekly asymptomatic/symptomatic testing (March 2020-October 2021) and serology pre-/post-two-dose Pfizer-BioNTech BNT162b2 vaccination for (i) anti-nucleocapsid, (ii) quantified anti-receptor binding domain (RBD) antibodies at three time-intervals, (iii) pseudovirus neutralisation, and (iv) inhibition by anti-RBD competitive ELISA were conducted. Neutralisation activity: antibody titre relationship was assessed via beta linear-log regression and RBD antibody-binding inhibition: post-vaccine infection relationship by Wilcoxon rank sum test. RESULTS Here we show neutralising antibody titres are 9.2-fold (95% CI 5.8-14.5) higher associated with hybrid immunity (p < 0.00001); +7.5-fold (95% CI 4.6-12.1) with asymptomatic infection; +20.3-fold, 95% (CI 9.7-42.5) with symptomatic infection. A strong association is observed between antibody titre: neutralising activity (p < 0.00001) and rising anti-RBD antibody titre: RBD antibody-binding inhibition (p < 0.001), although 18/169 (10.7%) participants with high anti-RBD titre (>100BAU/ml), show inhibition <75%. Higher RBD antibody-binding inhibition values are associated with hybrid immunity and reduced likelihood of infection (p = 0.003). CONCLUSIONS Hybrid immunity in older adults was associated with considerably higher antibody titres, neutralisation and inhibition capacity. Instances of high anti-RBD titre with lower inhibition suggests antibody quantity and quality as independent potential correlates of protection, highlighting added value of measuring inhibition over antibody titre alone to inform vaccine strategy.

Abstract
Interstitial lung disease and associated fibrosis occur in a proportion of individuals who have recovered from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection through unknown mechanisms. We studied individuals with severe coronavirus disease 2019 (COVID-19) after recovery from acute illness. Individuals with evidence of interstitial lung changes at 3 to 6 months after recovery had an up-regulated neutrophil-associated immune signature including increased chemokines, proteases, and markers of neutrophil extracellular traps that were detectable in the blood. Similar pathways were enriched in the upper airway with a concomitant increase in antiviral type I interferon signaling. Interaction analysis of the peripheral phosphoproteome identified enriched kinases critical for neutrophil inflammatory pathways. Evaluation of these individuals at 12 months after recovery indicated that a subset of the individuals had not yet achieved full normalization of radiological and functional changes. These data provide insight into mechanisms driving development of pulmonary sequelae during and after COVID-19 and provide a rational basis for development of targeted approaches to prevent long-term complications.

Abstract
Objectives Real-world evaluation of the performance of the Innova lateral flow immunoassay antigen device (LFD) for regular COVID-19 testing of hospital workers. Methods This prospective cohort analysis took place at a London NHS Trust. 5076 secondary care healthcare staff participated in LFD testing from 18 November 2020 to21 January 2021. Staff members submitted results and symptoms via an online portal twice weekly. Individuals with positive LFD results were invited for confirmatory SARS CoV-2 PCR testing. The positive predictive value (PPV) of the LFD was measured. Secondary outcome measures included time from LFD result to PCR test and staff symptom profiles. Results 284/5076 individuals reported a valid positive LFD result, and a paired PCR result was obtained in 259/284 (91.2%). 244 were PCR positive yielding a PPV of 94.21% (244/259, 95% CI 90.73% to 96.43%). 204/259 (78.8%) staff members had the PCR within 36 hours of the LFD test. Symptom profiles were confirmed for 132/244 staff members (54.1%) with positive PCR results (true positives) and 13/15 (86.6%) with negative PCR results (false positives). 91/132 true positives (68.9%) were symptomatic at the time of LFD testing: 65/91 (71.4%) had symptoms meeting the PHE case definition of COVID-19, whilst 26/91 (28.6%) had atypical symptoms. 18/41 (43.9%) staff members who were asymptomatic at the time of positive LFD developed symptoms in the subsequent four days. 9/13 (76.9%) false positives were asymptomatic, 1/13 (7.7%) had atypical symptoms and 3/13 (23.1%) had symptoms matching the PHE case definition. Conclusions The PPV of the Innova LFD is high when used amongst hospital staff during periods of high prevalence of COVID-19, yet we find frequent use by symptomatic staff rather than as a purely asymptomatic screening tool. LFD testing does allow earlier isolation of infected workers and facilitates detection of individuals whose symptoms do not qualify for PCR testing.

Abstract
We describe two cases involving male foreign nationals (a Chinese and a Georgian) treated in a U.S. hospital. Both patients had terminal illnesses, and both cases involved clashes between families and the treating physicians, which occurred because of differing cultural beliefs about truth disclosure. Based on the specific backgrounds of these two patients, we discuss ethical and cultural considerations and make suggestions for physicians who care for ethnically diverse patients.

Abstract
Schizophrenia is a common, genetically heterogeneous disorder with a lifetime prevalence of approximately 1% in the general population. Linkage studies of affected families have now strongly implicated a susceptibility locus on chromosome 8p21-22. Tests of allelic association with markers on 8p21-22 should be able to localise any quantitative trait nucleotides (QTN's) or susceptibility mutations to within a few hundred kilobases. Three brain expressed candidate susceptibility genes, prepronociceptin (PNOC), neuronal cholinergic receptor, nicotinic, alpha polypeptide 2 (CHRNA2) and arylamine N-acetyltransferase 1 (NAT1) have been mapped to chromosome 8p21-22. A case-control, allelic association study was performed using a novel highly polymorphic dinucleotide repeat, D8S2611 near the PNOC gene, two previously characterised dinucleotide repeats, D8S131 and D8S131P at the CHRNA2 locus and an RFLP at the 3'UTR of the arylamine N-acetyltransferase 1 (NAT1) gene. No differences were found in allele frequencies between the patient and control groups. DNA variations or mutations at or near the three genes under study are unlikely to increase susceptibility to schizophrenia in our population sample.

Abstract
The UGT1 locus is felt to be highly conserved between species, as is evident from the characterization of the locus in rodents and humans. In rabbits, cDNAs encoding proteins homologous to human UGT1A4, UGT1A6, and UGT1A7 have previously been identified. Here we demonstrate by Southern blot analysis, using exon 1 divergent 5' segments from rabbit UGT1A4 and UGT1A6 cDNAs, the existence of a cluster of highly related genes that are homologous to each of these exon 1 sequences. In comparing rabbit and human, it is evident that the UGT1A4 and UGT1A6 gene clusters in rabbit have undergone gene duplication. This is particularly evident with rabbit UGT1A6. The human UGT1A6 cDNA anneals to only a single gene fragment, as displayed by Southern blot analysis, indicating that the UGT1A6 exon 1 sequence is highly conserved. However, up to six rabbit UGT1A6 genes could be predicted from Southern blot analysis. To examine the potential linkage of the rabbit UGT1A6 genes, multiple UGT1A6 exons were identified from genomic DNA by extended polymerase chain reaction techniques and cloning of the UGT1A6 exon 1 sequences. Five unique UGT1A6 exon 1 gene sequences were characterized that could be predicted to encode proteins that are 98% similar in amino acid structure. Using a conserved region of the rabbit UGT1A6 cDNA as a probe to screen cDNA libraries, we identified a second UGT1A6 cDNA, termed UGT1A6alpha. In addition, a cDNA that encodes a protein similar to human UGT1A3 was also cloned. Characterization of UGT1A6alpha demonstrated the protein to be 98.9% identical to UGT1A6. The expression of rabbit UGT1A3, UGT1A4, and UGT1A6 displayed catalytic activities similar to their human orthologs. However, UGT1A6alpha was catalytically divergent from UGT1A6, indicating that UGT1A6 and UGT1A6alpha do not arise from allelic polymorphism. These results demonstrate that lagomorphs have evolved at least five additional UGT1A6 genes, an event that is not duplicated in rodents or humans.

Abstract
Conventional methods of imaging in the investigation of developmental dysplasia of the hip all have disadvantages, either in definition or in exposure to radiation. We describe a new open-configuration MR scanner which is unique in that it allows anaesthesia and access to the patient within the imaging volume for surgical procedures and application of casts. We performed 13 scans in eight anaesthetised infants. Dynamic imaging revealed two dislocated hips which were then visualised during reduction. Hip spicas were applied without removing the patient from the scanner. In one hip, an adductor tenotomy was carried out. In all patients, stressing the hips during dynamic imaging allowed an assessment of stability. This was particularly useful in two hips in which an analysis of stability in different positions facilitated the planning of femoral osteotomies. This method of imaging provides new and important information. It has great potential in the investigation of developmental dysplasia of the hip and, with ultrasound, may allow management without the need for radiography.

Abstract
Interventional MR (IMR) machines have produced unique opportunities for image-guided surgery. The open configuration design and fast pulse sequences allow intraoperative scanning to monitor procedures. This study was undertaken to assess the potential use of IMR for image-guided surgery. Benign breast lesion excision was chosen as an uncomplicated surgical model. Ten female patients with known benign tumors underwent excision biopsy under general anesthesia in a Signa SP10 .5-T IMR machine (General Electric Medical Systems, Milwaukee, WI). Lesions were localized with precontrast and postcontrast (intravenous gadolinium-diethylenetriamine pentaacetic acid, .2 mmol/kg) fast multiplanar spoiled gradient-recalled acquisition in the steady state (GRASS) sequences. Preoperative "real-time" fast gradient-recalled sequences were also obtained using the Flashpoint (General Electric Medical Systems, Milwaukee, WI) tracker device. The maximum dimensions of each lesion were measured from the resulting images. Excision was performed using titanium instruments and an ultrasonically activated scalpel. Intraoperative real-time scanning demonstrated the resection margin and confirmed complete excision. The maximum dimensions of the macroscopic specimens were compared with those from the MR images. All tumors were visualized with the Signa scanner and real-time imaging and the images were enhanced after intravenous contrast. Maximum dimensions on histologic examination were not significantly different from those measured from Signa (P > .17) or real-time images (P > .4). There was no significant difference between lesion size from Signa and real-time images (P > .25). All postprocedure scans demonstrated complete excision. There were six fibroadenomas, two foci of sclerosing adenosis, one area of fibrocystic disease, and one schwannoma. Intraoperative MR scanning reliably identifies palpable breast tumors and can accurately guide surgical excision. Further work using MR guidance can now be performed in other general surgical areas.

Abstract
Thirty-nine clubfeet undergoing primary soft tissue release for idiopathic clubfoot deformity had intrinsic compartment pressure monitoring for 36 h after surgery. This was done to determine whether pressures might be elevated to levels, and for durations, such that an intrinsic compartment syndrome might develop. Two groups were identified: in group 1 (23 feet) pressures were never elevated to > 20 mm Hg; in group 2 (16 feet) pressures > 30 mm Hg for a duration of at least 12 h were found. In a subgroup of group 2 (4 of 16 feet), pressures were > 50 mm Hg for at least 12 h. There was no statistical correlation between pressure recordings and surgeon, tourniquet time, severity of deformity, extent of release, and type of cast used. Thus 40% of feet are at risk of developing pressures that could cause an intrinsic compartment syndrome.

Abstract
Peri-operative increase of oxygen delivery has been shown to reduce mortality in high-risk surgical patients. This study compares the effectiveness of dopexamine and dobutamine when used to increase cardiac output as part of a regimen to increase oxygen delivery. Sixteen surgical patients were randomly allocated to receive either dopexamine or dobutamine, which was increased to a stable dose defined as either oxygen delivery index > 600 ml/min/m2, or tachycardia > 20% above baseline, other dysrhythmias or angina. At this "stable" dose there were significant increases in cardiac index (2.4 +/- 0.2 vs 3.7 +/- 0.3 l/min/m2) and oxygen delivery (380 +/- 73 vs 579 +/- 40 ml/min/m2) in the dopexamine group (P < 0.05); but not the dobutamine group. Five out of eight patients receiving dopexamine and three out of eight receiving dobutamine reached target oxygen delivery. Three dobutamine patients, but no dopexamine patients, had angina or dysrhythmias. In preoperative high-risk surgical patients, dopexamine can allow greater increases in oxygen delivery than dobutamine, due to cardiac effects that limit the dobutamine infusion rate.

Abstract
Coumadin is a coumarin anticoagulant that induces a state similar to vitamin K deficiency and is routinely used for chronic oral anticoagulation. Intramural hematoma of the bowel is a rare complication of anticoagulant therapy. In this paper, we describe such a case of an anticoagulated patient who had complaints of abdominal pain and who had inadvertently been taking higher dose of coumadin. Although the diagnosis can usually be made by history and plain abdominal x-ray, we report here some radiographic signs that can be seen on a CT-scan of the abdomen and are relatively specific for this diagnosis. We stress the importance of recognizing the disorder because the management is conservative and surgery is reserved for cases in which no improvement is seen.

Abstract
OBJECTIVE Studies in animals have indicated that increased production of nitric oxide from an inducible isoform of nitric oxide synthase contributes to the pathophysiology of endotoxic and cytokine induced shock. The aim of this study was to determine the role of nitric oxide in septic shock in humans. METHODS The study was a randomised, double blind, placebo controlled investigation of the effects of the nitric oxide synthase inhibitor NG monomethyl-L-arginine (L-NMMA) in 12 patients with severe sepsis associated with hypotension. Measurements of haemodynamic, haematological, and biochemical variables were made. RESULTS L-NMMA (0.3 and 1 mg.kg-1) produced a dose dependent increase in mean arterial pressure, systemic vascular resistance, pulmonary vascular resistance, central venous pressure, and pulmonary artery occlusion pressure, and a decrease in cardiac output and heart rate. In response to the highest dose of L-NMMA systemic vascular resistance increased from 547(SEM 92) to 889(143) dyne.s.cm-5, mean arterial blood pressure increased from 80.9(2.9) to 100.5(6.1) mm Hg, and cardiac output decreased from 11.2(2.1) to 8.9(1.9) litres.min-1. Continuous infusion of L-NMMA (1 mg.kg-1 x h-1) produced sustained haemodynamic changes. Platelet numbers decreased during the course of the study in both the L-NMMA and the placebo group and did not differ significantly between the groups. CONCLUSIONS Low doses of L-NMMA cause a widespread increase in vascular tone and raise blood pressure in patients with septic shock. Overproduction of nitric oxide appears to be an important mechanism in septic shock in patients, and inhibition of nitric oxide synthesis might provide a novel therapeutic approach to this condition. However, L-NMMA produced a fall in cardiac output and it is possible that this would worsen tissue perfusion. Larger studies examining the effects of L-NMMA on mortality and morbidity are now required.

Abstract
The measurement of gastric intramucosal pH (pHi) has been advocated to assist in decision-making for critically ill patients. To assess whether the information obtained from the measurement of pHi can be obtained from other measurements of metabolic acidosis, we studied 20 consecutive patients admitted to the intensive care unit. A mean of eight (range two to fourteen) data sets per patient were obtained, comprising measurement of arterial pH, pO2, pCO2, and oxygen saturation, tonometer balloon fluid pCO2, arterial pressures, and cardiac output. Bicarbonate concentration, base deficit or excess in blood and extracellular fluid, and pHi were calculated from these measurements. Relations between the variables and pHi were assessed by within-subject correlation comparisons. There were significant correlations (r > 0.6, p < 0.001) between markers of metabolic acidosis (base deficit in blood and extracellular fluid and bicarbonate concentration) and pHi. A blood base deficit of -4.65 or less and an extracellular-fluid base deficit of -6.13 or less could estimate pHi below 7.32 (lower limit of normal range) with sensitivity of at least 77% and specificity of at least 96%. There was no patient in whom either pHi or blood base deficit consistently reflected acidosis when the other variable did not. We conclude that the information that is obtained by gastric tonometry for pHi can be obtained more simply from measurements of metabolic acidosis; these variables can be calculated from routinely available blood-gas measurements.

Abstract
The techniques used to examine the psychometric properties of instruments that measure concepts where individual responses are aggregated to form an index describing a group level phenomenon are reviewed. This examination includes assessing the content validity of items to determine how well they measure group level concepts as well as analyzing reliability and validity at the aggregated rather than individual level. Additional techniques to test for within and between group variability are presented. The latter approaches are useful in determining the consistency and adequacy of individual responses at the group level.

Abstract
Little is known about the impact of the cancer experience on long-term survivors of adult cancers. This exploratory study describes survivors' needs and identifies emic (in the subject's own words) categories and patterns among physiological, psychological, and socioeconomic changes, problems/concerns, and needs. A purposive sample of 17 adults more than two years post-cancer therapy was interviewed using the semi-structured Cancer Survivor Questionnaire (CSQ). Deductive content analysis was used to identify specific changes, problems/concerns, or needs associated with physiological, psychological, and socioeconomic categories. Inductive content analysis identified major emic themes and patterns. Findings indicate that the cancer experience permanently changes life patterns and suggest guidelines for nurses to use in helping the cancer survivor better adapt holistically to long-term survival.

Abstract
Intradermal inoculation of metacyclic forms of Trypanosoma congolense propagated in vitro caused skin reactions in goats similar to the local skin reaction (chancre) induced by the bite of an infected tsetse fly. The onset, size and duration of these local skin reactions were dose-dependent. Whereas one cultured metacyclic T. congolense was sufficient to cause a local skin reaction in a goat, over 10(7) bloodstream forms of T. congolense were necessary to elicit a detectable skin reaction and while T. congolense parasites present in lymph did not cause local skin reactions, trypanosomes collected from oedematous fluid of the chancre did. - Using non-dividing irradiated bloodstream forms it was estimated that 10(8) T. congolense were required to induce a detectable local skin reaction. - Intradermal needle inoculation of procyclic forms (uncoated trypomastigotes) of T. congolense propagated in vitro induced an intense inflammatory response which was similar to that found in the early phases of the reaction elicited by metacyclic trypanosomes. This suggests that the uncoated trypomastigotes which are known to be present in the saliva of infected tsetse may play a role in the initial development of the chancre. - The data obtained for the local skin reaction suggest the presence of an intracutaneous dividing stage of T. congolense which is intermediate between the metacyclic and bloodstream forms.

Abstract
The preoperative detection of visible liver metastases in patients with colorectal cancer is important in determining a rational treatment policy. The accuracy of haptic ultrasound scanning was assessed in 100 patients with primary colorectal cancer. Each patient had a 99mTc-sulphur colloid scan, ultrasound scan, and liver function test. All patients came to laparotomy and the liver was carefully palpated. With very few exceptions the combination of isotope and ultrasound scanning gave accurate information on the state of the liver in all patients in this series. Alkaline phosphatase was the only enzyme whose serum activity was consistently elevated in the presence of liver metastases. Ultrasound scanning of the liver is a simple, safe, accurate, and non-invasive method for preoperative assessment of the state of the liver in patients with primary colorectal cancer.

Abstract
Children who are frequently or persistently absent from school tend to perform poorly in school and are likely to drop out before graduation from high school. Excessive school absence was significant implications in terms of maladaptive behavior, wasted opportunities, and future unemployment and welfare costs. Epidemiologic information about this problem suggests that physical and mental health problems of students or their families are the sole or contributing cause of this behavior in more than 50% of cases. Excessive school absence may signal such health problems as poor coping with or management of chronic illness, masked depression, teenage pregnancy, substance abuse, inappropriate responses to minor illnesses, or severe family dysfunction. School absence patterns appear to be a readily available, easy-to-use marker of childhood dysfunction which lends itself to screening large numbers of children for unmet health needs. Attention to this area of child behavior as part of routine health care will frequently uncover previously unrecognized health problems in children and their families.
