Abstract
Background CT lymphangiography has been used to image the lymphatic anatomy and assess lymphatic abnormalities. There is, however, a need to develop a method for quantification of lymphatic flow rate in the thoracic duct (TD). Purpose To develop and validate a TD lymphatic flow measurement technique using dynamic contrast-enhanced CT lymphangiography. Materials and Methods Lymphatic flow rate was measured with two techniques: a first-pass analysis technique based on a single compartment model and a thresholding technique distinguishing between opacified and nonopacified voxels within the TD. The measurements were validated in a swine animal model between November 2021 and September 2022. CT images were acquired at 100 kV and 200 mA using a fast-pitched helical scan mode covering the entire TD following contrast material injection into the bilateral inguinal lymph nodes. Two helical CT scans, acquired at the base and peak contrast enhancement of the TD, were used to measure lymphatic flow rate. A US flow probe surgically placed around the TD provided the reference standard measurement. CT lymphatic flow measurements were compared with the reference US flow probe measurements using regression and Bland-Altman analysis. Repeatability was determined using repeated flow measurements within approximately 10 minutes of each other. Results Eleven swine (10 male; mean weight, 43.6 kg ± 2.6 [SD]) were evaluated with 71 dynamic CT acquisitions. The lymphatic flow rates measured using the first-pass analysis and thresholding techniques were highly correlated with the reference US flow probe measurements (r = 0.99 and 0.91, respectively) and showed good agreement with the reference standard, with Bland-Altman analysis showing small mean differences of 0.04 and 0.05 mL/min, respectively. The first-pass analysis and thresholding techniques also showed good agreement for repeated flow measurements (r = 0.94 and 0.90, respectively), with small mean differences of 0.09 and 0.03 mL/min, respectively. Conclusion The first-pass analysis and thresholding techniques could be used to accurately and noninvasively quantify TD lymphatic flow using dynamic contrast-enhanced CT lymphangiography. © RSNA, 2023 See also the editorial by Choyke in this issue.

Abstract
A 77-year-old man with history of sacral chordoma and pulmonary embolism presented to the emergency room with a 1-day history of diffuse left flank and lower extremity swelling. The patient was found to have thrombus in the left common and external iliac veins. The patient was brought to Interventional Radiology for mechanical thrombectomy using the Inari ClotTriever and a sample of extracted thrombus was sent to pathology. Analysis on the sample was positive for sacral chordoma, consistent with tumor thrombus. The patient returned after 6 weeks with similar symptoms and repeat mechanical thrombectomy was performed with the Inari ClotTriever and stent placement through the left common and external iliac vein with an Ovation iX stent graft. The patient remained asymptomatic following the second procedure at repeat follow-up at 6 weeks.

Abstract
In the era of precision medicine, biopsies are playing an increasingly central role in cancer research and treatment paradigms; however, patient outcomes and analyses of biopsy quality, as well as impact on downstream clinical and research applications, remain underreported. Herein, we report biopsy safety and quality outcomes for percutaneous core biopsies of hepatocellular carcinoma (HCC) performed as part of a prospective clinical trial. Patients with a clinical diagnosis of HCC were enrolled in a prospective cohort study for the genetic, proteomic, and metabolomic profiling of HCC at two academic medical centers from April 2016 to July 2020. Under image guidance, 18G core biopsies were obtained using coaxial technique at the time of locoregional therapy. The primary outcome was biopsy quality, defined as tumor fraction in the core biopsy. 56 HCC lesions from 50 patients underwent 60 biopsy events with a median of 8 core biopsies per procedure (interquartile range, IQR, 7–10). Malignancy was identified in 45/56 (80.4%, 4 without pathology) biopsy events, including HCC (40/56, 71.4%) and cholangiocarcinoma (CCA) or combined HCC-CCA (5/56, 8.9%). Biopsy quality was highly variable with a median of 40% tumor in each biopsy core (IQR 10–75). Only 43/56 (76.8%) and 23/56 (41.1%) samples met quality thresholds for genomic or metabolomic/proteomic profiling, respectively, requiring expansion of the clinical trial. Overall and major complication rates were 5/60 (8.3%) and 3/60 (5.0%), respectively. Despite uniform biopsy protocol, biopsy quality varied widely with up to 59% of samples to be inadequate for intended purpose. This finding has important consequences for clinical trial design and highlights the need for quality control prior to applications in which the presence of benign cell types may substantially alter findings.

Abstract
PURPOSE To compare clinical performance of 2 widely used symmetric-tip hemodialysis catheters. MATERIALS AND METHODS Patients with end-stage renal disease initiating or resuming hemodialysis were randomized to receive an Arrow-Clark VectorFlow (n = 50) or Palindrome catheter (n = 50). Primary outcome was 90-d primary unassisted catheter patency. Secondary outcomes were Kt/V ([dialyzer urea clearance × total treatment time]/total volume of urea distribution), urea reduction ratio (URR), and effective blood flow (QB). RESULTS Primary unassisted patency rates with the VectorFlow catheter at 30, 60, and 90 d were 95.5% ± 3.3, 87.2% ± 7.3, and 80.6% ± 9.8, respectively, compared with 89.1% ± 6.2, 79.4% ± 10.0, and 71.5% ± 12.6 with the Palindrome catheter (P = .20). Patients with VectorFlow catheters had a mean Kt/V of 1.5 at 30-, 60-, and 90-day time points, significantly higher than the mean Kt/V of 1.3 among those with Palindrome catheters (P = .0003). URRs were not significantly different between catheters. Catheter QB rates exceeded National Kidney Foundation-recommended thresholds of 300 mL/min at all time points for both catheters and were similar for both catheters (median, 373 mL/min). Catheter failure, ie, poor flow rate requiring guide-wire exchange or removal, within the 90-day primary outcome occurred in 3 VectorFlow subjects and 5 Palindrome subjects (P = .72). Infection rates were similar, with 0.98 infections per 1,000 catheter days for VectorFlow catheters compared with 2.62 per 1,000 catheter days for Palindrome catheters (P = .44). CONCLUSIONS The 90-day primary patency rates of Palindrome and VectorFlow catheters were not significantly different, and both achieved sustained high QB through 90 day follow-up. However, dialysis adequacy based on Kt/V was consistently better with the VectorFlow catheter versus the Palindrome.

Abstract
The quantification of forests available for wood supply (FAWS) is essential for decision-making with regard to the maintenance and enhancement of forest resources and their contribution to the global carbon cycle. The provision of harmonized forest statistics is necessary for the development of forest associated policies and to support decision-making. Based on the National Forest Inventory (NFI) data from 13 European countries, we quantify and compare the areas and aboveground dry biomass (AGB) of FAWS and forest not available for wood supply (FNAWS) according to national and reference definitions by determining the restrictions and associated thresholds considered at country level to classify forests as FAWS or FNAWS. FAWS represent between 75 and 95 % of forest area and AGB for most of the countries in this study. Economic restrictions are the main factor limiting the availability of forests for wood supply, accounting for 67 % of the total FNAWS area and 56 % of the total FNAWS AGB, followed by environmental restrictions. Profitability, slope and accessibility as economic restrictions, and protected areas as environmental restrictions are the factors most frequently considered to distinguish between FAWS and FNAWS. With respect to the area of FNAWS associated with each type of restriction, an overlap among the restrictions of 13.7 % was identified. For most countries, the differences in the FNAWS areas and AGB estimates between national and reference definitions ranged from 0 to 5 %. These results highlight the applicability and reliability of a FAWS reference definition for most of the European countries studied, thereby facilitating a consistent approach to assess forests available for supply for the purpose of international reporting.

Abstract
UNLABELLED Ethnic differences in renal calcium and phosphate excretion exist, which may depend on differences in their dietary intakes and regulatory factors. We report highly significant differences in urinary calcium and phosphate excretion between white British and Gambian adults after statistical adjustment for mineral intakes, indicating an independent effect of ethnicity. INTRODUCTION Populations vary in their risk of age-related osteoporosis. There are racial or ethnic differences in the metabolism of the bone-forming minerals calcium (Ca) and phosphate (P), with a lower renal Ca and P excretion in African-Americans compared to white counterparts, even at similar intakes and rates of absorption. Also, Africans in The Gambia have a lower Ca excretion compared to white British subjects, groups known to differ in their dietary Ca intake. Here, we report on differences in urinary Ca and P excretion between Gambian and white British adults while allowing for known predictors, including dietary intakes. METHODS Participants were healthy white British (n = 60) and Gambian (n = 61) men and women aged 60-75 years. Fasting blood and 2-h urine samples were collected. Markers of Ca and P metabolism were analysed. Dietary intake was assessed with country-specific methods. RESULTS White British older adults had higher creatinine-corrected urinary Ca and P excretion (uCa/uCr, uP/uCr) and lower tubular maximum of Ca and P compared to Gambian counterparts. The predictors of urinary Ca and P differed between groups. Multiple regression analysis showed that dietary Ca and Ca/P were predictors of uCa/uCr and uP/uCr, respectively. Ethnicity remained a significant predictor of uCa/uCr and uP/uCr after adjustment for diet and other factors. CONCLUSIONS Gambian older adults have higher renal Ca conservation than British counterparts. Dietary mineral intakes were predictors of the differences in urinary Ca and P excretion, but ethnicity remained a highly significant predictor after statistical adjustment. This suggests that ethnicity has an independent effect on renal Ca and P handling.

Abstract
The prevalence of osteoporosis and the incidence of age-related fragility fracture vary by ethnicity. There is greater than 10-fold variation in fracture probabilities between countries across the world. Mineral and bone metabolism are intimately interlinked, and both are known to exhibit patterns of daily variation, known as the diurnal rhythm (DR). Ethnic differences are described for Ca and P metabolism. The importance of these differences is described in detail between select ethnic groups, within the USA between African-Americans and White-Americans, between the Gambia and the UK and between China and the UK. Dietary Ca intake is higher in White-Americans compared with African-Americans, and is higher in White-British compared with Gambian and Chinese adults. Differences are observed also for plasma 25-hydroxy vitamin D, related to lifestyle differences, skin pigmentation and skin exposure to UVB-containing sunshine. Higher plasma 1,25-dihydroxy vitamin D and parathyroid hormone are observed in African-American compared with White-American adults. Plasma parathyroid hormone is also higher in Gambian adults and, in winter, in Chinese compared with White-British adults. There may be ethnic differences in the bone resorptive effects of parathyroid hormone, with a relative skeletal resistance to parathyroid hormone observed in some, but not all ethnic groups. Renal mineral excretion is also influenced by ethnicity; urinary Ca (uCa) and urinary P (uP) excretions are lower in African-Americans compared with White-Americans, and in Gambians compared with their White-British counterparts. Little is known about ethnic differences in the DR of Ca and P metabolism, but differences may be expected due to known differences in lifestyle factors, such as dietary intake and sleep/wake pattern. The ethnic-specific DR of Ca and P metabolism may influence the net balance of Ca and P conservation and bone remodelling. These ethnic differences in Ca, P and the bone metabolism may be important factors in the variation in skeletal health.

Abstract
Objectives: We reviewed the utility of rigid bronchoscopy in the management of complications resulting from placement of metallic endobronchial stents after lung transplantation. Methods: A retrospective review was performed of all lung transplant patients who required metallic endobronchial stenting between 2005 and 2009. The patients' medical records were reviewed, and details regarding stent placement, complications, and removal were recorded. Results: A total of 43 metallic stents were placed in 22 patients who had unilateral or bilateral lung transplantation. Stent complications occurred in 18 cases (42%) at a mean of 285 days after placement and included stent collapse, stent breakdown, stent migration, ingrowth of granulation tissue, and coughing up of fractured pieces of stent. Of the 43 stents placed, only 4 (9%) had to be removed. Removal was readily accomplished by rigid bronchoscopic techniques, even when some endothelial ingrowth had occurred. Conclusions: Lung transplantation presents unique challenges in airway management. Endobronchial stenting plays an important role in the management of anastomotic stenosis and bronchomalacia in these patients. Although metallic stents have significant advantages, complications often arise that occasionally necessitate their removal. Rigid bronchoscopy is a valuable tool in the management of endobronchial stent complications after lung transplantation.

Abstract
We present the case of a 48-year-old HIV-positive man, who developed acute onset of pain in both upper limbs associated with proximal weakness and distal paraesthesia. Eight weeks prior to this presentation he had had varicella zoster affecting his right S1 dermatome. CD4 count was 355 cells/mm(3) and he was antiretroviral therapy (ART) naive. Power was 0/5 proximally and 4/5 distally in the upper limbs. Reflexes were absent and there was sensory loss in the C5, C6 and T1 dermatomes. Cerebrospinal fluid (CSF) examination showed a lymphocytosis with low glucose; however, CSF Mycobacterium tuberculosis (TB), and herpes simplex virus polymerase chain reaction (HSV PCR) were negative as was syphilis serology. Electromyography showed marked motor axonal loss. Magnetic resonance imaging (MRI) did not show any cervical spinal lesion. Varicella zoster virus (VZV) PCR was positive in the CSF. He was treated with high-dose intravenous aciclovir with good resolution of his syndrome over time and was commenced on ART. We believe this to be the first case report of varicella reactivation causing bilateral neuralgic amyotrophy in an HIV-positive patient.

Abstract
A retrospective chart review was carried out at the HIV clinic in St. James's Hospital, Dublin to examine the rate of cognitive impairment through the use of surrogate markers for cognitive impairment. 500 consecutive hospital charts were reviewed. There were 306 men and 194 women. Median age was 37. The most common mode of transmission was heterosexual. 45% had a nadir CD4 < 200. 78.6% were on antiretroviral therapy and 72.26% were virally suppressed. 69/500 patients (13.8%) had one or more positive surrogate markers for cognitive impairment. The surrogate markers used were subjective complaints, a new onset of a psychiatric diagnosis post diagnosis with HIV, neurological complications and radiological evidence of atrophy. Multivariate analysis using logistic regression showed significant relationships only with gender and year of diagnosis. This figure is lower than reported international prevalence rates of cognitive impairment and demonstrates that surrogate markers are no match for structured cognitive screening. We have since commenced structured prospective screening to obtain a true prevalence of cognitive impairment in this population.

Abstract
Lambert-Eaton myasthenic syndrome (LEMS) is a rare autoimmune disorder of neuromuscular transmission (NMJ) that shares many clinical features with myasthenia gravis (MG). We report a 73 year-old lady who presented 10 years previously with stiffness of both calves, dry mouth, fatigue, proximal weakness and areflexia in lower limbs. Neurophysiological studies were consistent with LEMS. Her work up for an underlying neoplasm was negative. She recently developed unilateral ptosis and diplopia which dramatically improved with pyridostigmine suggesting concomitant MG.

Abstract
Previous work made use of nucleic acid probes corresponding to different subtypes of the class II regions of the human and murine major histocompatibility complex (MHC) to isolate seven different alpha and 24 different beta genes of the ovine MHC from two cosmid libraries. In an attempt to identify pairs of alpha and beta genes capable of cell surface expression, all permutations of alpha and beta genes were in turn transfected into mouse L-cells. Two pairs of alpha and beta genes co-expressed and stable ovine MHC class II L-cell lines were developed. The expressed alpha genes had previously been defined as DR-alpha homologues (DRA) by differential Southern hybridization to human subtype specific class II probes. The expressed ovine beta genes were also assigned as ovine DR-beta homologues (DRB) on the basis of their sequence having a higher degree of similarity with human DRB than any other subtype. A total of eight out of 23 anti-sheep class II specific monoclonal antibodies were typed OLA-DR specific by FACScan analysis using the L-cell lines.

Abstract
BACKGROUND Aseptic meningitis is a frequent diagnostic problem, with little data available regarding its prevalence and the commonly identified causes. AIMS To identify the common diagnostic tests requested, and their subsequent yields in obtaining a diagnosis in adult cases of aseptic meningitis in a tertiary neurological and infectious disease centre. METHODS Cases of aseptic meningitis were retrospectively reviewed for a 2-year period. RESULTS Of the 43 cases reviewed, a diagnosis based on subsequent microbiological, histological and immunological testing was obtained in 17 (40%). Altered levels of consciousness, and higher CSF protein levels were significantly more common in those patients attaining a definite diagnosis. CONCLUSION The median duration of admission to hospital in the undiagnosed group was 12 days, which may be improved with increased accuracy and availability of diagnostic techniques such as polymerase chain reaction.

Abstract
Studies on the immunoglobulin (Ig)E immune responses to the gastric nematode, Teladorsagia circumcincta, have demonstrated a major high molecular weight allergen (HMWTc). Cross reactive allergens of similar MW were demonstrated for Trichostrongylus colubriformis and Cooperia curticei, but not for Haemonchus contortus. Purification of HMWTc was achieved by gel-filtration chromatography, and nonreducing SDS-PAGE and Western blot analysis revealed two closely associated bands with a molecular weight of approximately 140-150 kDa. Reduction showed four IgE reactive bands of 120, 50, 45 and 30 kDa, and deglycosylation abrogated the immunoreactivity of the 120 and 30 kDa bands. Ultrastructural immunolocalization by electron microscopy revealed that the IgE reactivity was confined to the cuticular surface of the infective (L3) larvae. ELISA studies to determine the IgE anti-HMWTc responses in lambs during their first grazing season, demonstrated significantly higher IgE antibody in lambs with low accumulative faecal egg count (FEC) compared to animals with high accumulative FEC. These studies provide evidence for a protective function of IgE antibody in Teladorsagia infections in lambs.

Abstract
The effects of different doses of filgrastim on yields of CD34+ peripheral blood stem cells were evaluated in patients with breast cancer. 55 were randomized to receive filgrastim 10, 20, 30 or 40 microg/kg/d with more CD34+ cells/kg/apheresis harvested after the three highest dose levels. 35 additional patients were randomized to receive 10 or 30 microg/ kg. The median number of CD34+ cells collected after 10 microg/ kg (n = 31) was 0.7 x 10(6)/kg/apheresis (range 0.1-4.4) as compared to 1.2 (range 0.1-6.8) after 30 microg/kg (n = 32) (P = 0.04). Among patients randomized to 10 v 30 microg/kg, more (50%) achieved > or = 5.0 x 10(6) CD34+ cells/kg and less aphereses were required to achieve > or = 2.5 x 10(6) CD34+ cells/kg after the higher dose (P = 0.04). In multivariate analyses, patients receiving 10 microg/kg (n = 31) had lower yields of CD34+ cells (P = 0.026) and had a 3.3-fold increase in the probability of not achieving > or = 5.0 x 10(6) CD34+ cells/kg as compared to patients receiving 20-40 microg/kg (n = 59). Patients who had received radiation had a 2.9-fold probability of not achieving > or = 2.5 x 10(6) CD34+ cells/kg. These data suggest that, in patients with good marrow reserves, doses of filgrastim > 10 microg/kg/d mobilized more CD34+ cells and may be useful when high numbers of CD34+ cells are desired.

Abstract
Cellulose, an abundant, crystalline polysaccharide, is central to plant morphogenesis and to many industries. Chemical and ultrastructural analyses together with map-based cloning indicate that the RSW1 locus of Arabidopsis encodes the catalytic subunit of cellulose synthase. The cloned gene complements the rsw1 mutant whose temperature-sensitive allele is changed in one amino acid. The mutant allele causes a specific reduction in cellulose synthesis, accumulation of noncrystalline beta-1,4-glucan, disassembly of cellulose synthase, and widespread morphological abnormalities. Microfibril crystallization may require proper assembly of the RSW1 gene product into synthase complexes whereas glucan biosynthesis per se does not.

Abstract
Engraftment kinetics after high-dose chemotherapy (HDC) were evaluated in patients receiving autologous peripheral blood stem cell (PBSC) infusions with a low CD34+ cell content. Forty-eight patients were infused with < 2.5 x 10(6) CD34+ cells/kg; 36 because of poor harvests and 12 because they electively received only a fraction of their harvested cells. A median of 2.12 x 10(6) CD34+ cells/kg (range, 1.17-2.48) were infused following one of seven different HDC regimens. All patients achieved absolute neutrophil counts > or = 0.5 x 10(9)/l at a median of day 11 (range, 9-16). Forty-seven patients achieved platelet counts > or = 20 x 10(9)/l at a median of day 14 (range, 8-250). Nine of 47 (19%) had platelet recovery after day 21, 4/47 (9%) after day 100 and one died on day 240 without platelet recovery. Twenty-six patients (54%) died of progressive disease in 51-762 days; 22 (46%) are alive at a median of 450 days (range, 94-1844), 17 (35%) of whom are surviving disease-free at a median of 494 days (range, 55-1263). No patient died as a direct consequence of low blood cell counts. These data demonstrate that PBSC products containing 1.17-2.48 x 10(6) CD34+ cells/kg resulted in relatively prompt neutrophil recovery in all patients but approximately 10% had delayed platelet recovery.

Abstract
The prevalence of peripheral nerve dysfunction was assessed in 24 randomly selected adult patients with cystic fibrosis. Median, peroneal and sural nerves were studied. In 15 patients (62%), one or more electrical abnormality were detected. In the median nerve, conduction velocity was slowed in 29% of sensory studies and 12.5% of motor studies; compound muscle action potential (CMAP) and sensory nerve action potential (SNAP) amplitudes were normal. The CAMP was low in 17% of peroneal studies with motor conduction velocity slow in 8%. The sural SNAP was low in 17% and sensory nerve conduction velocity slow in 25%. Using a multiple regression analysis only age at diagnosis was identified as a significant predictor of peripheral nerve dysfunction (multiple R = 0.55; p < 0.01). This study demonstrates that mild peripheral nerve dysfunction is common in patients with cystic fibrosis. With the improving long term survival of these patients we predict that the prevalence and severity of this complication will increase.

Abstract
Bilateral synchronous testicular cancer is a rare occurrence usually associated with similar histologic findings in each testicle. We describe eight patients with bilateral synchronous testicular germ cell cancer, of whom four had dissimilar histologic findings. Contralateral disease in three patients was identified only by testicular ultrasonography or intraoperative exploration of the contralateral testicle, and in two cases by palpation 6 months after identification of the primary cancer. Treatment was determined by conventional staging and five of eight patients have remained free of recurrent disease.

Abstract
Granulocyte colony-stimulating factor is a glycoprotein that promotes the proliferation and differentiation of neutrophils. It also results in an increase in circulating hematopoietic progenitor cells. We describe two cases of extramedullary hematopoiesis in patients receiving granulocyte colony-stimulating factor with chemotherapy for metastatic breast cancer.

Abstract
Acquired pure red cell aplasia (PRCA) has been associated with various lymphoproliferative conditions but its occurrence with Hodgkin's disease is rare. We report a case of PRCA occurring immediately following the completion of induction chemotherapy in a patient with Stage IIIB nodular sclerosing Hodgkin's disease. In vitro erythroid colony studies documented evidence for T cell mediated suppression of erythropoiesis and lack of a serum inhibitor. Addition of cyclosporin to the in vitro cultures stimulated erythroid colony growth. Following in vivo treatment with cyclosporin peripheral blood CD4/CD8 ratios returned to normal. However, serum erythropoietin levels were inappropriately low. Subsequent treatment with erythropoietin induced a reticulocytosis and transfusion independence. Since discontinuing the erythropoietin, the patient has been able to maintain a hemoglobin of 100 g/L. This case illustrates that red cell aplasia occurring in the setting of Hodgkin's disease may be due to T cell mediated suppression of erythropoiesis. A response to cyclosporin may be masked by inappropriately low erythropoietin levels.

Abstract
Iron malabsorption compounded the anemia in a patient with diffuse large cell lymphoma involving the small intestine. Both upper gastrointestinal series with small bowel follow-through and computerized tomographic scan demonstrated lymphomatous involvement of the duodenum and proximal jejunum by a retroperitoneal mass. An oral iron-loading absorption test was consistent with malabsorption of iron. After two cycles of systemic chemotherapy, the retroperitoneal mass resolved and the iron loading test normalized.

Abstract
Small cell lung cancer is an aggressive neoplasm; metastases are detected in two-thirds of patients at diagnosis with use of conventional staging, which includes bilateral bone marrow biopsy, bone scintigraphy, and computed tomography (CT) of the head and abdomen. In 25 patients, small cell lung cancer was staged prospectively with both conventional staging and a magnetic resonance (MR) imaging protocol that included 1.5-T MR imaging of the pelvis, abdomen, spine, and brain. According to conventional staging, 14 patients had extensive disease and 11 patients had limited disease; according to staging with MR, 19 patients had extensive disease and six had limited disease. All metastatic disease sites seen with conventional staging were identified on MR images. MR images showed additional metastatic involvement in bone (four patients) and liver (three patients) not detected at conventional staging. A low-attenuation hepatic lesion on a CT scan was identified as a hemangioma on MR images. These preliminary data suggest that small cell lung cancer may be accurately staged with use of a single MR imaging study.
