Abstract
PURPOSE/OBJECTIVE(S) Roughly 50-67% of patients with squamous cell carcinomas of the head and neck (SCCHN) present with locally advanced (LA) disease and 65% of them relapse after initial therapy. The standard of care for LA SCCHN is definitive therapy (DT), a combination of surgery and or radiation therapy (RT), with or without platinum-based chemotherapy/cetuximab (chemo), that has been shown to optimize long term disease control. Few published analyses have characterized recent real-world treatment (Tx) patterns of older adults with LA SCCHN in the US. MATERIALS/METHODS We used the Surveillance, Epidemiology, and End Results (SEER)-Medicare database, a linkage of cancer registry and claims data, to identify patients diagnosed with LA SCCHN (first and only cancer) from 2010 to 2017 who initiated a relevant Tx (Tx initiation date defined as index date) and were continuously enrolled in Medicare Parts A, B, and D from 12 months pre-index until death or 12 months post-index. We used clinical guidelines regarding timing and frequency of treatments to build an algorithm that used Medicare claims to categorize initial Tx as non-DT, non-surgical DT (concomitant chemo+RT (cCRT) or chemotherapy before RT/cCRT), or surgical DT (surgery then RT/cCRT ± prior chemo). RESULTS We identified 1052 older adults with LA SCCHN (median age 73 years, 37% female, and 81% non-Hispanic white) whose initial treatment was started a median of 26 days after initial diagnosis. Of the 610 patients who received a DT as their initial Tx, 23.3% of patients had a subsequent Tx: 3.8% received immunotherapy-containing regimens (IO), and the most common subsequent Tx were surgery only (7.7%), chemotherapy only (3.6%), and RT only (3.4%). The median time to next Tx (TTNT) differed by DT category and primary tumor site. (Table 1) CONCLUSION: In this descriptive analysis, we provided an update on the Tx patterns of older adults with LA SCCHN in the US, for whom there have been no novel FDA approvals in over a decade. We found that a large proportion (42%) of patients did not receive DT regimens in the real-world setting despite known benefits in LA SCCHN. Roughly a quarter of patients required subsequent Tx. Availability of IO was low due to approvals after 2017. These findings suggest a need for novel therapies that can improve outcomes in LA SCCHN.

Abstract
PURPOSE/OBJECTIVE(S) Approximately 50-67% of patients with squamous cell carcinomas of the head and neck (SCCHN) present with locally advanced (LA) disease. Human papillomavirus (HPV) associated SCCHN has improved survival compared to non-HPV SCCHN. Studies have analyzed racial disparities in LA SCCHN but few have adjusted for HPV status and socio-economic status (SES). Our objective was to characterize disparities in LA SCCHN. MATERIALS/METHODS We identified high-risk patients from 2010-2017 with AJCC v8 Stage IVA/IVB SCCHN of the oral cavity, oropharynx (OP), larynx or hypopharynx, or Stage III SCCHN of the OP in the Surveillance, Epidemiology, and End Results (SEER) with HPV Status and Census Tract-level SES/Rurality Combined Database. We excluded OP patients with missing HPV data. SEER-reported treatment was used to classify initial treatment as definitive therapy (DT) categories: surgical DT, non-surgical DT or non-DT. The Kaplan Meier method was used to estimate overall survival (OS) with 95% confidence intervals (CI). Multivariable cox proportional hazard models were used for associations between covariates and hazard ratio (HR) of death, adjusted for age, sex, race, ethnicity, DT category, marital status, rurality, tumor size, cancer stage, and HPV status. We explored the impact of additionally adjusting for Yost SES index quintiles. RESULTS We identified 17,818 eligible patients: 79.3% White, 14.4% Black, 5.8% Asian/Pacific Islander (A/PI), and 0.6% American Indian/Alaska Native (AI/AN). Primary tumor sites were oral cavity (36.8%), larynx (29.0%), OP (24.4%), and hypopharynx (9.9%). 10.4% were HPV-associated. Race and SES quintiles were related (chi-squared, p<0.001) and the majority (56.5%) of black patients were in the lowest SES quintile. mOS was shorter and risk of death was significantly higher for black vs white patients in both the all-site and OP-only cohorts. When we added SES to multivariable analyses, Black race was no longer associated with increased risk of death in the all-site or OP-only cohorts. (Table 1) CONCLUSION: We found that when adjusting for sociodemographic and clinical factors, Black race was independently associated with a higher risk of death compared to white patients. When we adjusted for SES in multivariable analysis the association between Black race and risk of death was no longer significant, consistent with previously published analyses and indicative of a complex relationship between race and SES. Further research is needed to identify and address the causative factors of disparities in LA HNSCC.

Abstract
RATIONALE Stereotactic body radiation therapy (SBRT) is the standard of care for inoperable early stage non-small cell lung cancer (NSCLC). Use of image guided thermal ablation (IGTA; including microwave ablation [MWA] and radiofrequency ablation [RFA]) has increased in NSCLC, however there are no studies comparing all three. OBJECTIVE To compare the efficacy of IGTA (including MWA and RFA) and SBRT for the treatment of NSCLC. METHODS Published literature databases were systematically searched for studies assessing MWA, RFA, or SBRT. Local tumor progression (LTP), disease-free survival (DFS), and overall survival (OS) were assessed with single-arm pooled analyses and meta-regressions in NSCLC patients and a stage IA subgroup. Study quality was assessed with a modified methodological index for non-randomized studies (MINORS) tool. RESULTS Forty IGTA study-arms (2,691 patients) and 215 SBRT study-arms (54,789 patients) were identified. LTP was lowest after SBRT at one and two years in single-arm pooled analyses (4% and 9% vs. 11% and 18%) and at one year in meta-regressions when compared to IGTA (OR = 0.2, 95%CI = 0.07-0.63). MWA patients had the highest DFS of all treatments in single-arm pooled analyses. In meta-regressions at two and three-years, DFS was significantly lower for RFA compared to MWA (OR = 0.26, 95%CI = 0.12-0.58; OR = 0.33, 95%CI = 0.16-0.66, respectively). OS was similar across modalities, timepoints, and analyses. Older age, male patients, larger tumors, retrospective studies, and non-Asian study region were also predictors of worse clinical outcomes. In high-quality studies (MINORS score ≥ 7), MWA patients had better clinical outcomes than the overall analysis. Stage IA MWA patients had lower LTP, higher OS, and generally lower DFS, compared to the main analysis of all NSCLC patients. CONCLUSIONS NSCLC patients had comparable outcomes after SBRT and MWA, which were better than those with RFA.

Abstract
Abstract
Introduction
The International Society of Geriatric Oncology recommends using screening tools to identify cancer patients who would benefit from a comprehensive geriatric assessment. G8, a tool specifically designed for oncology, has been well validated in this setting (1). Rockwood Clinical frailty score (CFS) is a widely used tool to assess frailty, and has been adopted into standard assessments at many sites (2). However, this tool is less well validated in patients with cancer.
Methods
In this single site observational study we recorded CFS and G8 in 89 patients with lung cancer referred to a local onco-geriatrics clinic between 21/10/20 and 5/2/21. Both scores were available for 82 patients. We aimed to measure the correlation between G8 and CFS in this cohort.
Results
G8 score ≤ 14 is a referral criteria for the clinic, therefore 100% (82/82) of patients were classified as ‘frail’ using G8. Of these, only 23.2% (19/82) were classified as ‘mildly frail’ or worse using CFS (scores ≥5). Using Spearman’s rank correlation we found a very weak/negligible negative correlation between CFS and G8 (−0.2519, p = 0.0224).
Conclusion
The small proportion of patients (23.2%) classified as frail by CFS suggests that a G8 cut off of 14 may overestimate frailty. Previous work by our group has found that using a cut off of 13 is better able to predict chemotherapy outcomes(3). However, considering the lack of evidence for CFS in oncology, this poor correlation between G8 and CFS may question the usefulness of CFS in this context.

Abstract
Fast radio bursts (FRBs) are flashes of unknown physical origin1. The majority of FRBs have been seen only once, although some are known to generate multiple flashes2,3. Many models invoke magnetically powered neutron stars (magnetars) as the source of the emission4,5. Recently, the discovery6 of another repeater (FRB 20200120E) was announced, in the direction of the nearby galaxy M81, with four potential counterparts at other wavelengths6. Here we report observations that localized the FRB to a globular cluster associated with M81, where it is 2 parsecs away from the optical centre of the cluster. Globular clusters host old stellar populations, challenging FRB models that invoke young magnetars formed in a core-collapse supernova. We propose instead that FRB 20200120E originates from a highly magnetized neutron star formed either through the accretion-induced collapse of a white dwarf, or the merger of compact stars in a binary system7. Compact binaries are efficiently formed inside globular clusters, so a model invoking them could also be responsible for the observed bursts.

Abstract
Various techniques have been explored to prolong the duration and improve the efficacy of local anaesthetic nerve blocks. Some of these involve mixing local anaesthetics or adding adjuncts. We did a literature review of studies published between 01 May 2011 and 01 May 2021 that studied specific combinations of local anaesthetics and adjuncts. The rationale behind mixing long- and short-acting local anaesthetics to hasten onset and extend duration is flawed on pharmacokinetic principles. Most local anaesthetic adjuncts are not licensed for use in this manner and the consequences of untested admixtures and adjuncts range from making the solution ineffective to potential harm. Pharmaceutical compatibility needs to be established before administration. The compatibility of drugs from the same class cannot be inferred and each admixture requires individual review. Precipitation on mixing (steroids, non-steroidal anti-inflammatory drugs) and subsequent embolisation can lead to serious adverse events, although these are rare. The additive itself or its preservative can have neurotoxic (adrenaline, midazolam) and/or chondrotoxic properties (non-steroidal anti-inflammatory drugs). The prolongation of block may occur at the expense of motor block quality (ketamine) or block onset (magnesium). Adverse effects for some adjuncts appear to be dose-dependent and recommendations concerning optimal dosing are lacking. An important confounding factor is whether studies used systemic administration of the adjunct as a control to accurately identify an additional benefit of perineural administration. The challenge of how best to prolong block duration while minimising adverse events remains a topic of interest with further research required.

Abstract
The DEAP-3600 detector searches for the scintillation signal from dark matter particles scattering on a 3.3 tonne liquid argon target. The largest background comes from 39 Ar beta decays and is suppressed using pulse-shape discrimination (PSD). We use two types of PSD estimator: the prompt-fraction, which considers the fraction of the scintillation signal in a narrow and a wide time window around the event peak, and the log-likelihood-ratio, which compares the observed photon arrival times to a signal and a background model. We furthermore use two algorithms to determine the number of photons detected at a given time: (1) simply dividing the charge of each PMT pulse by the mean single-photoelectron charge, and (2) a likelihood analysis that considers the probability to detect a certain number of photons at a given time, based on a model for the scintillation pulse shape and for afterpulsing in the light detectors. The prompt-fraction performs approximately as well as the log-likelihood-ratio PSD algorithm if the photon detection times are not biased by detector effects. We explain this result using a model for the information carried by scintillation photons as a function of the time when they are detected.

Abstract
Aim COVID19 pandemic has significantly affected surgical services. We aim to review its effects on our theatre output and risk of encountering COVID 19 cases. Method Serial record of operations performed locally were reviewed from start of UK COVID19 pandemic lockdown on 23rd March 2020 to 13th July 2020 after it was lifted. A weekly average by month of operations and the percentage of COVID19 cases diagnosed within 30 days of the procedure were noted. Results 733 operations performed through this period. In March, 33 operations/week performed, 88.4% emergency and 7% diagnosed with COVID19. April, 31 operations /week performed, 95.9% emergency and 10.6% diagnosed with COVID19. May 46 operations /week performed, 94.5% emergency and 3.3% diagnosed with COVID19. June 56 operations /week, 80.9% emergency and less than 0.01% diagnosed with COVID19. By July 80 operations/week, 59.4% emergency and none diagnosed with COVID 19. Since testing capacity increased, only 6 of the 27 operated were diagnosed with COVID19. Conclusions There was initial reduction to non-emergency workload. However, this has gradually shifted as protocols are in place improve public confidence to return for surgical treatment. Mandatory admission testing allows early identification and remains essential for planning of services and protecting the workforce.

Abstract
INTRODUCTION Recurrence rates remain high after surgical treatment of diffuse-type Tenosynovial Giant Cell Tumour (TGCT). Imatinib Mesylate (IM) blocks Colony Stimulating Factor1 Receptor (CSF1R), the driver mechanism in TGCT. The aim of this study was to determine if IM reduces the tumour metabolic activity evaluated by PET-CT and to compare this response with the response seen on MR imaging. MATERIALS AND METHODS 25 Consecutive patients treated with IM (off label use) for locally advanced (N = 12) or recurrent (N = 13) diffuse-type TGCT were included, 15 male and median age at diagnosis 39 (IQR 31-47) years. The knee was most frequently affected (n = 16; 64%). The effect of IM was assessed pre- and post-IM treatment by comparing MR scans and PET-CT. MR scans were assessed by Tumour Volume Score (TVS), an estimation of the tumour volume as a percentage of the total synovial cavity. PET-CT scans were evaluated based on maximum standardized uptake value (SUV-max). Partial response was defined as more than 50% tumour reduction with TVS and a decrease of at least 30% on SUV-max. RESULTS Median duration of IM treatment was 7.0 (IQR 4.2-11.5) months. Twenty patients (80%) discontinued IM treatment for poor response or intended surgery. Twenty patients experienced an adverse event grade 1-2, three patients grade 3 (creatinine increment, neutropenic sepsis, liver dysfunction). MR assessment of all joints showed 32% (6/19) partial response and 63% (12/19) stable disease, with a mean difference of 12% (P = 0.467; CI -22.4-46.0) TVS between pre- and post-IM and a significant mean difference of 23% (P = 0.021; CI 4.2-21.6) in all knee lesions. PET-CT, all joints, showed a significantly decreased mean difference of 5.3 (P = 0.004; CI 1.9-8.7) SUV-max between pre- and post-IM treatment (58% (11/19) partial response, 37% (7/19) stable disease). No correlation between MR imaging and PET-CT could be appreciated in 15 patients with complete radiological data. CONCLUSION This study confirms the moderate radiological response of IM in diffuse-type TGCT. PET-CT is a valuable additional diagnostic tool to quantify response to tyrosine kinase inhibitor treatment. Its value should be assessed further to validate its efficacy in the objective measurement of biological response in targeted systemic treatment of TGCT.

Abstract
INTRODUCTION A service model was established for pregnant women with positive screening results for hepatitis B surface antigen (HBsAg) at Queen Mary Hospital in Hong Kong. All women were offered a blood test for hepatitis B virus (HBV) DNA level during the first antenatal visit. Women with HBV DNA levels of ≥200 000 IU/mL received counselling from hepatologists regarding treatment with antenatal tenofovir disoproxil fumarate (TDF) 300 mg daily. METHODS This retrospective review included women attending our antenatal clinic who exhibited positive HBsAg screening results from 15 May 2017 to 31 December 2019. The proportions of women with positive HBsAg, DNA test acceptance, hepatological review, and TDF acceptance during pregnancy were reviewed. RESULTS In total, 375 (2.9%) of 13 082 pregnant women had positive HBsAg screening results. Blood tests for HBV DNA and hepatological reviews were offered to 273 women who had not undergone hepatological review prior to pregnancy; the acceptance rate was 97.8%. Sixty (22.6%) pregnant women were hepatitis B carriers with high viral loads of ≥200 000 IU/mL. Among 58 women with high viral loads, 57 received antenatal counselling regarding TDF and 56 (96.6%) agreed to take the drug; 92.9% of these 56 women had commenced TDF at or before 32 weeks of gestation. CONCLUSIONS This study indicated broad acceptance of HBV DNA tests by pregnant women. Triage allowed early review and commencement of antiviral medication. This service model serves as a framework for enhanced antenatal service to prevent mother-to-child-transmission in public maternity units.

Abstract
BACKGROUND We report the results of International Nosocomial Infection Control Consortium (INICC) surveillance study from January 2012 to December 2017 in 523 intensive care units (ICUs) in 45 countries from Latin America, Europe, Eastern Mediterranean, Southeast Asia, and Western Pacific. METHODS During the 6-year study period, prospective data from 532,483 ICU patients hospitalized in 242 hospitals, for an aggregate of 2,197,304 patient days, were collected through the INICC Surveillance Online System (ISOS). The Centers for Disease Control and Prevention-National Healthcare Safety Network (CDC-NHSN) definitions for device-associated health care-associated infection (DA-HAI) were applied. RESULTS Although device use in INICC ICUs was similar to that reported from CDC-NHSN ICUs, DA-HAI rates were higher in the INICC ICUs: in the medical-surgical ICUs, the pooled central line-associated bloodstream infection rate was higher (5.05 vs 0.8 per 1,000 central line-days); the ventilator-associated pneumonia rate was also higher (14.1 vs 0.9 per 1,000 ventilator-days,), as well as the rate of catheter-associated urinary tract infection (5.1 vs 1.7 per 1,000 catheter-days). From blood cultures samples, frequencies of resistance, such as of Pseudomonas aeruginosa to piperacillin-tazobactam (33.0% vs 18.3%), were also higher. CONCLUSIONS Despite a significant trend toward the reduction in INICC ICUs, DA-HAI rates are still much higher compared with CDC-NHSN's ICUs representing the developed world. It is INICC's main goal to provide basic and cost-effective resources, through the INICC Surveillance Online System to tackle the burden of DA-HAIs effectively.

Abstract
Abstract
Rationale: while large efforts have been done to characterize early breast cancer, little is known about the genomic landscape of metastatic breast cancer. In the present study, we performed whole exome sequencing of 800 metastatic breast cancers, in order to identify new candidate targets and better stratify patients eligible for innovative therapies.
Patients and Methods: Patients were selected to present a metastatic breast cancer and to have received a biopsy in the context of precision medicine trials (SAFIR01, SAFIR02, PERMED, MOSCATO, SHIVA). Samples with >30% cancer cells, and normal DNA, were sequenced using Hiseq and Novaseq. Drivers were identified using MutSigCV. Actionability of somatic genetic alterations was determined based on OncoKB. Decomposition of mutational signatures was performed using deconstructSigs. Prognostic value was assessed using a cox model. TCGA database was used as comparator to identify gene alterations enriched in metastatic samples.
Results: results presented in the current abstract are based on the first 629 patients analyzed.Sequencing was performed in 387 patients with HR+/Her2- breast cancer, 186 triple negative breast cancers, and 32 Her2-overexpressing breast cancers. only 9 patients received a pretreatment with a CDK4 inhibitor. 24 driver genes were significantly mutated. In patients with HR+/Her2- breast cancer, 11 genes were found more frequently mutated in the metastatic setting as compared to early stage breast cancer. This includes TP53 (29%), KMT2C (13%), NCOR1 (8%), NF1 (7%), RB1 (4%), C16orf3 (2%), FRG1 (6%), ESR1 (21%), RIC8A (4%), AKT1 (7%), PLSCR5 (2%). In addition, in the whole population, KRAS was found mutated in 3% of samples (G12A/C/R/V) while its frequency of mutation in early breast cancer is <1%. No gene alteration was found enriched in metastatic Her2+++ and TNBC. Copy number alterations were compared between metastatic and early breast cancer. 18 amplicons were found more frequently in HR+/Her2- metastatic breast cancers as compared to eBC. Among the genes enriched in metastatic samples, mutations in RB1 or NF1 were associated with a poor outcome ( median OS 9 and 13 months respectively, p=0.0038 and 0.01 respectively). 73% of patients presenting HR+/Her2- mBC had an actionable alteration, as compared to 55% of patients presenting HR+/Her2- eBC (p<0.01). Patients with HR+/Her2- mBC presented an enrichment of gene alterations in the MAPK/ERK pathway (37% vs 22%) and in the HRD pathway (22% vs 10%). When the analysis focuses on mTNBC; the proportion of patient presenting an actionable alteration was comparable to the eTNBC. 11 (6%) and 16 (9%) patients presented a somatic mutation or homozygous gene deletion on BRCA1 and PTEN respectively.
We further assessed the mutational signatures in order to better understand which mutational processes could drive cancer progression. Metastatic HR+/Her2- mBC presented an increase in APOBEC, S3 (HRD), S10 (POLE-associated signature), S17 signatures as compared to early HR+/Her2- BC.
Conclusion: the present study, based on 629 patients, identifies 11 driver gene alterations and four mutational processes enriched in HR+/Her2- metastatic breast cancers. Final results on 800 patients will be presented.

Abstract
The demand for blood products continues to grow in an unsustainable manner in Hong Kong. While anaemia associated with gastrointestinal bleeding (GIB) is the leading indication for transfusion, there is no local recommendation regarding best practices for transfusion. We aimed to provide evidence-based recommendations regarding management of anaemia in patients with acute and chronic GIB. We reviewed all original papers, meta-analyses, systematic reviews, or guidelines that were available in PubMed. For acute GIB, a restrictive transfusion strategy, targeting a haemoglobin threshold of 7 to 8 g/dL, should be adopted because overtransfusion is associated with significantly higher all-cause mortality and re-bleeding. A liberal transfusion strategy should only be considered in patients with co-existing symptomatic coronary artery disease, targeting a haemoglobin threshold of 9 to 10 g/dL. When acute GIB settles, patients should be prescribed iron supplements if iron deficiency is present. For chronic GIB, iron stores should be replenished aggressively via iron supplementation before consideration of blood transfusion, except in patients with symptoms of severe anaemia. Oral iron replacement is the preferred first-line therapy, while intravenous iron is indicated for patients with inflammatory bowel disease, poor response or poor tolerability to oral iron, and in whom a rapid correction of iron deficit is preferred. Intravenous iron is underutilised and the risk of anaphylactic reaction to current preparations is extremely low. These recommendations are provided to local clinicians to facilitate judicious and appropriate use of red cell products and iron replacement therapy in patients with GIB.

Abstract
Generalized arterial calcification of infancy (GACI) is a rare genetic disorder with high infantile mortality, described to be due to ENPP1, and less commonly ABCC6 mutations. Bisphosphonate treatment has been described to improve survival in ENPP1-positive GACI patients, but few studies have described bisphosphonate treatment in ABCC6-positive patients. Without therapy, patients will die before 6 months of age. Our patient is now 3 years old, former recipient twin of twin-to-twin transfusion syndrome (TTTS). Initial fetal echocardiogram at 19 weeks showed calcifications of the ascending aorta and pulmonary artery (PA). She underwent utero laser therapy, and despite resolution of the TTTS, her follow-up scans showed progressive calcification of the aorta and PA. Postnatal echocardiogram showed calcification and supravalvar stenosis of the aorta and PA. CT on day of life 6 showed calcifications in the PAs, aortic arch, and descending aorta. Quantification of valvular calcification can be difficult; in our patient, increasing outflow tract gradient on echocardiogram was used to monitor disease progression. Molecular testing revealed an ABCC6 gene mutation. She was started on weekly IV pamidronate (0.1-0.3 mg/kg/week) on day 8 of life then transitioned to oral etidronate (15-20 mg/kg/day). Given progressive supravalvar aortic and pulmonary stenosis, she underwent surgical repair with patch augmentation of the PA and ascending aorta at 4 months old. She has done well post-operatively, continuing on enteral bisphosphonate therapy with no side effects to date. Her identical twin was confirmed to have the same mutation and remains asymptomatic with no calcifications. Aggressive bisphosphonate therapy should be started as soon as possible in patients with infantile arterial calcinosis due to ABCC6 or ENPP1 mutations. Echocardiographic evaluation can be used to monitor disease progression by arterial gradients. Molecular testing is also essential to evaluate for possible co-morbidities in these patients and pregnancy management for the future.

Abstract
This Letter reports the first results of a direct dark matter search with the DEAP-3600 single-phase liquid argon (LAr) detector. The experiment was performed 2 km underground at SNOLAB (Sudbury, Canada) utilizing a large target mass, with the LAr target contained in a spherical acrylic vessel of 3600 kg capacity. The LAr is viewed by an array of PMTs, which would register scintillation light produced by rare nuclear recoil signals induced by dark matter particle scattering. An analysis of 4.44 live days (fiducial exposure of 9.87 ton day) of data taken during the initial filling phase demonstrates the best electronic recoil rejection using pulse-shape discrimination in argon, with leakage <1.2×10^{-7} (90% C.L.) between 15 and 31 keV_{ee}. No candidate signal events are observed, which results in the leading limit on weakly interacting massive particle (WIMP)-nucleon spin-independent cross section on argon, <1.2×10^{-44} cm^{2} for a 100 GeV/c^{2} WIMP mass (90% C.L.).

Abstract
OBJECTIVE The author evaluated graft and patient outcomes of renal allograft recipients with hepatitis B infection at National Kidney and Transplant Institute from January 2000 to December 2010. METHODS Retrospective study with patients who underwent renal transplant with HBV infection and group of HBV-negative patients in the same post-transplantation period. Data were gathered from the patients' in-hospital and out-patient clinic records and the MEDSYS database. RESULTS A total of 38 renal transplant recipients were followed up. Hepatitis B cases had a 410% increased risk of having graft failure compared to hepatitis B-negative patients. The mean duration of graft survival was 145.26 (±60.40) months (12 years) in HBV negative compared to 134.29 (±67.94) months (11 years) in HBV-positive post-transplant patients. There was no difference between hepatitis B-positive and B-negative groups in terms of patient survival. The mean duration of patient survival was 156.97 (±60.62) months (13 years) in HBV negative compared to 157.37 (±61.09) months (13 years) in HBV positive post-transplant patients. There was also no significant difference in the mean values of the glomerular filtration rate and level of proteinuria between the two groups. CONCLUSION Although patient survival was similar in both groups, there was increased risk of graft failure in hepatitis B-positive patients.
