Abstract
OBJECTIVE Our aim in this study was to determine the safety, glycemia, and quality of life (QoL) associated with in-clinic installation and management of supported open-source artificial pancreas systems (SOSAPS) in type 1 diabetes (T1D). METHODS This investigation is a retrospective cohort study of consecutive SOSAPS users at a Canadian diabetes centre. SOSAPS were offered to all moderately tech-savvy T1D clients on sensor-augmented multiple daily injection or pump, able to pay for hardware, and willing to sign a consent and waiver document. SOSAPS were installed and maintained by clinic staff at no cost to clients. iPhone users were assigned to either Loop (n=108) or iPhone artificial pancreas systems (iAPS; n=114) and Android users to Android-type APS (n=24). Outcomes included severe hypoglycemia and diabetic ketoacidosis (DKA), time in range (TIR) 4.0 to 10.0 mmol/L, time below range (TBR) <4 mmol/L, glucose management indicator (GMI), mean sensor glucose (MSG), change in glycated hemoglobin (A1C), and QoL. RESULTS Two hundred forty-eight subjects (131 males, 117 females), with a mean age of 36 years and diabetes duration of 21 years, experienced 3 episodes of severe hypoglycemia and no DKA over a follow-up of 17 months. TIR rose by 16%, from 64% to 80% (p<0.0001); TBR fell by 1.0%, from 3.5% to 2.5% (p=0.001); MSG fell from 9.0 to 8.1 mmol/L (p<0.001); GMI fell from 7.3% to 6.7% (p<0.001); and A1C fell from 7.2% to 6.7% (p<0.0001). QoL scores were healthy before and improved after SOSAPS. CONCLUSIONS Clients with T1D using SOSAPS and supported with no-cost care to the client (software, technology, and physician/physician assistant) safely achieved improved TIR, GMI, A1C, and QoL.

Abstract
Background Home enteral nutrition allows individuals to receive food and water through a tube at home when they are unable to meet their needs by mouth. To date, systematic literature reviews to date have focused on specific insertion methods, coordinated community care models, and prophylactic vs. reactive use. Few qualitative systematic reviews exist and those that do have only explored the lived experiences of sub-populations of adults using home enteral nutrition, such as those with head and neck cancers. Given healthcare services often serve adult home enteral nutrition populations with various underlying conditions, a synthesis describing the lived experiences of all adult using home enteral nutrition and caregivers is needed. Purpose To conduct a meta-aggregation systematic review to evaluate lived experiences of home enteral nutrition in adult users and their caregivers. Method A systematic search of Medline, PsychINFO, EmBase and CINAHL was conducted September 2021. Only studies with a full-text and published in English were included. Study quality was assessed using the Johanna Briggs Institute meta-aggregation methodology. Details of the study design, participants, and experiences were recorded, and themes across all studies collatedCollated themes were reviewed with a team of healthcare providers, home enteral nutrition users and a caregiver to ensure trustworthiness. Result(s) A total of 38 studies representing 702 participants were included. Using the meta-aggregative approach, three different synthesized findings were identified: (1) positive experiences, (2) negative experiences, and (3) facilitators and coping mechanisms. While, overall, the findings reported more negative experiences than positive experiences, users and caregivers who had developed coping mechanisms or had access to supportive services tended to share more positive experiences with home enteral nutrition. In contrast, those with few to no supports or coping mechanisms reported greater dissatisfaction and negative experiences. Image ![]()
Conclusion(s) Home enteral nutrition impacts the lived experience of users and their caregivers. While more negative than positive experiences were reported by adults and their caregivers using home enteral nutrition, overall, they still view home enteral nutrition as a positive intervention if they are adequate supported or developed adequate coping mechanisms. It is imperative that healthcare providers working with adults using home enteral nutrition explore and understand their patients’ and caregivers’ needs, in order to ensure community programs are designed to provide the necessary supports to maximize users experiences.

Abstract
AIMS We conducted a pooled analysis of four randomised controlled trials and a non-trial retrospective dataset to study the changes in serum prostate-specific antigen (PSA) concentrations during treatment and its impact on survival in men treated with docetaxel for metastatic castration-resistant prostate cancer. We also compared the outcomes and pre-treatment prognostic factors between trial and non-trial patients. MATERIALS AND METHODS Data were obtained from four randomised controlled trials and a non-trial cohort from a tertiary cancer centre. The PSA kinetics covariates chosen were absolute value (PSAT), best percentage change (BPCH) and tumour growth rate (K). The association between the covariates collected and overall survival was assessed within a Cox proportional hazards model. How well a covariate captured the difference between trial and non-trial patients was assessed by reporting on models with or without trial status as a covariate. RESULTS We reviewed individual datasets of 2282 patients. The median overall survival for trial patients was 20.4 (95% confidence interval 19.6-22.2) months and for the non-trial cohort was 12.4 (10.7-14.7) months (P < 0.001). Of the pre-treatment factors, we found that only lactate dehydrogenase fully captured the difference in prognosis between the trial and non-trial cohorts. All PSA kinetic metrics appeared to be prognostic in both the trial and non-trial patients. However, the effect size was reduced in non-trial versus trial patients (interaction P < 0.001). Of the time-dependent covariates, we found that BPCH best captured the difference between trial and non-trial patient prognosis. CONCLUSIONS The analysis presented here highlights how data from open-source trial databases can be combined with emerging clinical practice databases to assess differences between trial versus non-trial patients for particular treatments. These results highlight the importance of developing prognostic models using both pre-treatment and time-dependent biomarkers of new treatments.

Abstract
INTRODUCTION Evidence supporting use of continuous glucose monitoring in type 2 diabetes treated with basal insulin is unclear. This real-world study aimed to assess the impact on glycated hemoglobin (HbA1c) of flash glucose monitoring use in adults with type 2 diabetes managed with basal insulin. RESEARCH DESIGN AND METHODS Medical records were reviewed for adult individuals with type 2 diabetes using basal insulin for ≥1 year with or without additional antihyperglycemic medication, HbA1c 8.0%-12.0% prior to FreeStyle Libre Flash Glucose Monitoring use for ≥90 days and an HbA1c measurement recorded between 90 and 194 days after device use. Exclusion criteria included utilization of bolus insulin. Meta-analysis data are from the current study (USA) and a similar Canadian cohort. RESULTS Medical record analysis (n=100) from 8 USA study sites showed significant HbA1c decrease of 1.4%±1.3%, from 9.4%±1.0% at baseline to 8.0%±1.2% after device use, p<0.0001 (mean±SD).Meta-analysis of medical records from USA and Canada sites (n=191) showed HbA1c significantly decreased by 1.1%±0.14% (mean±SE), from baseline 9.2%±1.0% to 8.1%±1.1%, p≤0.0001, with moderate to high heterogeneity between sites (Q=43.9, I2=74.9, p<0.0001) explained by differences in baseline HbA1c between sites.The HbA1c improvement in both groups was observed by age group, body mass index, duration of insulin use and sex at birth. CONCLUSIONS In a real-world retrospective USA study and a meta-analysis of a larger USA and Canada cohort, HbA1c significantly reduced in basal insulin-treated type 2 diabetes, without bolus insulin initiation and following the commencement of flash glucose monitoring technology.

Abstract
BACKGROUND The real-world effect of intermittently scanned continuous glucose monitoring on glucose control in type 2 diabetes treated with basal insulin is uncertain. This retrospective real-world study aimed to evaluate change in glycated hemoglobin (HbA1c) amongst adults with type 2 diabetes managed with basal insulin starting flash glucose monitoring. METHODS Medical records were reviewed for adults with type 2 diabetes treated with basal insulin for ⩾1 year and using FreeStyle LibreTM Flash Glucose Monitoring for ⩾3 months. Prior to device use an HbA1c 8.0%-12.0% was recorded and a further HbA1c result was recorded 3-6 months (90-194 days) after starting device use. RESULTS Medical records (n = 91) analyzed from six Canadian diabetes centers showed HbA1c significantly decreased by 0.8% ± 1.1 (mean ± SD, [p < 0.0001]) from mean baseline HbA1c 8.9% ± 0.9 to 8.1% ± 1.0 at 3-6 months after initiating flash glucose monitoring. HbA1c improvement was not independently associated with age, BMI, insulin use duration, or sex. CONCLUSION This Canadian real-world retrospective study showed significantly reduced HbA1c following initiation of flash glucose monitoring technology to further support management of type 2 diabetes treated with basal insulin.

Abstract
BACKGROUND Glycerin suppositories are often used to facilitate meconium evacuation in premature infants. The evidence for this practice is inconclusive. The purpose of this study was to assess the feasibility of a multicenter randomized controlled trial on the effectiveness of this treatment strategy. STUDY DESIGN We conducted an external pilot study for a multicenter randomized controlled trial of premature infants randomized to glycerin suppositories or placebo procedure. Participants were included if they were gestational age of 24 weeks 0 days to 31 weeks 6 days and/or birthweight of 500 to 1500 grams. We excluded infants with life-threatening congenital anomalies, contraindications to receiving suppositories, or signs of clinical instability. Outcomes included cost, recruitment, and treatment-related adverse events. RESULT A total of 109 were screened, 79 were initially eligible, and 34 consented to participate. Four of these infants were excluded prior to randomization due to thrombocytopenia, 30 were randomized, and 26 reached full enteral feeds. Three infants (10%) experienced rectal bleeding 5 to 43 days after completing study treatments. An anal fissure was noted in two of these patients. There were no cases of rectal perforation but one infant assigned to active treatment developed necrotizing enterocolitis. CONCLUSIONS Conducting a multicenter randomized controlled trial on the use of glycerin suppositories in premature infants is feasible. Minor modifications to the study protocol are needed to increase participant recruitment and simplify the administration of study treatments.

Abstract
Introduction Inflammatory cell recruitment, which is potentially mediated by the monocyte chemoattractant protein 1/C-C chemokine receptor type 2 (CCR2) system and by C-C chemokine receptor type 5 (CCR5) activity, may play a role in the development and progression of diabetic nephropathy. PF-04634817 is a dual chemokine CCR2/5 receptor antagonist that is being developed for the treatment of diabetic nephropathy. Methods We evaluated the efficacy of PF-04634817 compared with matching placebo for reduction of albuminuria after 12 weeks of treatment in subjects with type 2 diabetes who received standard of care (SOC; angiotensin-converting enzyme inhibitor or angiotensin receptor blocker therapy), in a randomized, double-blind, placebo-controlled, parallel-group phase 2 study. Results A total of 226 subjects who received SOC with baseline estimated glomerular filtration rates between 20 and 75 ml/min per 1.73 m2 and a baseline urinary albumin-to-creatinine ratio (UACR) of ≥300 mg/g were randomly assigned 3:1 to receive PF-04634817 (150 or 200 mg orally, once daily) or placebo. The primary analysis was Bayesian, with an informative prior for placebo response (equivalent to including an additional 80 subjects in the placebo arm). We observed a placebo-adjusted reduction in UACR of 8.2% (ratio 0.918; 95% credible interval: 0.75–1.09) at week 12 in the PF-04634817 arm. PF-04634817 appeared to be safe and well-tolerated. Conclusion Despite the good safety profile shown by PF-04634817, clinical development for this indication was discontinued in light of the modest efficacy observed.

Abstract
PURPOSE To estimate the economic impact of a TegadermTM chlorhexidine gluconate (CHG) gel dressing compared with a standard intravenous (i.v.) dressing (defined as non-antimicrobial transparent film dressing), used for insertion site care of short-term central venous and arterial catheters (intravascular catheters) in adult critical care patients using a cost-consequence model populated with data from published sources. MATERIAL AND METHODS A decision analytical cost-consequence model was developed which assigned each patient with an indwelling intravascular catheter and a standard dressing, a baseline risk of associated dermatitis, local infection at the catheter insertion site and catheter-related bloodstream infections (CRBSI), estimated from published secondary sources. The risks of these events for patients with a Tegaderm CHG were estimated by applying the effectiveness parameters from the clinical review to the baseline risks. Costs were accrued through costs of intervention (i.e. Tegaderm CHG or standard intravenous dressing) and hospital treatment costs depended on whether the patients had local dermatitis, local infection or CRBSI. Total costs were estimated as mean values of 10,000 probabilistic sensitivity analysis (PSA) runs. RESULTS Tegaderm CHG resulted in an average cost-saving of £77 per patient in an intensive care unit. Tegaderm CHG also has a 98.5% probability of being cost-saving compared to standard i.v. dressings. CONCLUSIONS The analyses suggest that Tegaderm CHG is a cost-saving strategy to reduce CRBSI and the results were robust to sensitivity analyses.

Abstract
BACKGROUND Pre-treatment lymphocytopaenia may result from cytokines secreted by the tumour microenvironment in association with aggressive tumour biology. We sought to establish the prognostic significance of lymphocytopaenia in muscle-invasive and advanced bladder cancer. PATIENTS AND METHODS Seventy-four patients with muscle-invasive bladder cancer treated with radical chemoradiotherapy and 131 patients with advanced bladder cancer treated with palliative chemotherapy were included in the study. The absolute lymphocyte count on the first day of treatment was recorded. Invasive local or systemic recurrence in the muscle-invasive bladder cancer cohort and all-cause mortality in the advanced bladder cancer cohort were defined as survival end points. Receiver operating characteristic (ROC) curve analysis was utilized to determine the cut-off for defining lymphocytopaenia in the muscle-invasive bladder cancer cohort followed by multivariable analysis in a model evaluating the following variables: anaemia, neutrophilia, tumour stage, hydronephrosis and neoadjuvant chemotherapy. Subsequently, lymphocytopaenia was assessed in a multivariable model of the advanced bladder cancer cohort analysing the following prognostic variables: neutrophilia, anaemia, performance status and presence of bone or visceral metastases. A further analysis was carried out evaluating absolute lymphocyte count as a continuous variable. RESULTS An absolute lymphocyte count of 1.5 × 10(9)/l was determined as the cut-off on ROC curve analysis in the muscle-invasive bladder cancer cohort, and multivariate analysis revealed that only lymphocytopaenia was predictive for inferior outcome in this cohort. In the advanced bladder cancer cohort, lymphocytopaenia [hazard ratio (HR) 1.6, 95% confidence interval (CI) 1.1-2.4; P = 0.02] and performance status (HR 1.7, 95% CI 1.0-2.7; P = 0.047) were adverse prognostic factors in the binary variable multivariate model. Absolute lymphocyte count was the sole significant factor when analysed as a continuous variable (HR 0.66, 95% CI 0.5-0.87; P = 0.003). CONCLUSION Pre-treatment lymphocytopaenia is an independent adverse prognostic factor in both muscle-invasive and advanced bladder cancer. It may be a manifestation of cancer-induced immune suppression driving tumour progression.

Abstract
BACKGROUND AZD3514 is a first-in-class, orally bio-available, androgen-dependent and -independent androgen receptor inhibitor and selective androgen-receptor down-regulator (SARD). METHODS In study 1 and 2, castration-resistant prostate cancer (CRPC) patients (pts) were initially recruited into a once daily (QD) oral schedule (A). In study 1, pharmacokinetic assessments led to twice daily (BID) dosing (schedule B) to increase exposure. Study 2 explored a once daily schedule. RESULTS In study 1, 49 pts were treated with escalating doses of AZD3514 (A 35 pts, B 14 pts). Starting doses were 100 mg (A) and 1000 mg (B). The AZD3514 formulation was switched from capsules to tablets at 1000 mg QD. 2000 mg BID was considered non-tolerable due to grade (G) 2 toxicities (nausea [N], vomiting [V]). No adverse events (AEs) met the dose-limiting toxicity (DLT) definition. Thirteen pts received AZD3514 in study 2, with starting doses of 250 mg QD. The most frequent drug-related AEs were N: G1/2 in 55/70 pts (79 %); G3 in 1 pt (1.4 %); & V: G1/2 in 34/70 pts (49 %) & G3 in 1 pt (1.4 %). PSA declines (≥50 %) were documented in 9/70 patients (13 %). Objective soft tissue responses per RECIST1.1 were observed in 4/24 (17 %) pts in study 1. CONCLUSION AZD3514 has moderate anti-tumour activity in pts with advanced CRPC but with significant levels of nausea and vomiting. However, anti-tumour activity as judged by significant PSA declines, objective responses and durable disease stabilisations, provides the rationale for future development of SARD compounds.

Abstract
OBJECTIVES We compared 2 strategies for disseminating an evidence-based skin cancer prevention program. METHODS We evaluated the effects of 2 strategies (basic vs enhanced) for dissemination of the Pool Cool skin cancer prevention program in outdoor swimming pools on (1) program implementation, maintenance, and sustainability and (2) improvements in organizational and environmental supports for sun protection. The trial used a cluster-randomized design with pools as the unit of intervention and outcome. The enhanced group received extra incentives, reinforcement, feedback, and skill-building guidance. Surveys were collected in successive years (2003-2006) from managers of 435 pools in 33 metropolitan areas across the United States participating in the Pool Cool Diffusion Trial. RESULTS Both treatment groups improved their implementation of the program, but pools in the enhanced condition had significantly greater overall maintenance of the program over 3 summers of participation. Furthermore, pools in the enhanced condition established and maintained significantly greater sun-safety policies and supportive environments over time. CONCLUSIONS This study found that more intensive, theory-driven dissemination strategies can significantly enhance program implementation and maintenance of health-promoting environmental and policy changes. Future research is warranted through longitudinal follow-up to examine sustainability.

Abstract
The capsid (CA) protein of HIV-1, which forms the core of the virus, has been shown to have an increasingly important role in the early stages of the virus lifecycle, in particular during reverse transcription and nuclear import. We recently solved the structure of a fragment of the human cofactor CPSF6 in complex with the N-terminal domain of HIV-1 CA, revealing a previously unknown interface used by the virus to recruit CPSF6, which is required for the virus to successfully complete the early stages of its lifecycle. Using a recently developed hexameric unit of CA, we have solved the structure of the CPSF6 peptide with CA in a context that more closely resembles an intact CA lattice. This has revealed that CPSF6 contacts HIV-1 CA using an additional second site only present in the hexameric form of CA. Furthermore, we have now solved the structure of a fragment of NUP153 (an HIV-1 cofactor that is integral to the nuclear pore) in complex with hexameric CA and discovered that this also forms contacts specific to hexameric CA. Moreover, the binding sites for CPSF6 and NUP153 on CA overlap at one crucial residue, which is remarkably mimicked by two drugs independently discovered to bind at this same site. Together, these data provide evidence for an essential role for CA in HIV-1 infection, and highlights CA as an important target for antiretroviral drugs.

Abstract
OBJECTIVE To assess the effect of patient use of an online patient portal on diabetes outcomes. METHODS Patients included were those with diabetes who were newly referred to a Vancouver-based tertiary care diabetologist between April 2008 and October 2012. Each patient was assessed by the diabetologist, received initial diabetes education and was referred, as necessary, for further education and self-management training. All patients who provided an e-mail address at registration were invited to open an online patient portal account. The portal provided access to diabetes education material, personal laboratory values and a messaging system allowing communication with the diabetologist and staff. Patients who logged in 1 or more times were defined as portal users (n=50); patients who never logged in to the portal were defined as non-users (n=107). A1C was measured at 2 time points: at baseline (i.e. initial, in-clinic visit) and at last follow up (visit no less than 6 months and no more than 2 years after the initial visit). Because usership is self-selected, propensity score matching was used to create comparable user/non-user groups based on available baseline covariates. RESULTS Compared to non-users, a higher proportion of users achieved A1C ≤7% at follow up (56% vs. 32%) (p=0.031). CONCLUSION Accessing an online patient portal is associated with improved glycemic control.

Abstract
BACKGROUND Patients with cancer are often treated with glucocorticoids (gcs) as part of therapy, which may cause hyperglycemia. We sought to define the prevalence of, and risk factors for, hyperglycemia in this setting. METHODS Adult patients taking gc as part of therapy protocols for primary brain tumour or metastasis, for lymphoma, or for bone marrow transplant (bmt) were screened with random glucometer measurements taken at least 3 hours after the last dose gcs. RESULTS We screened 90 patients [44.4% women, 55.6% men; mean age: 59.6 years (range: 25-82 years); mean body mass index (bmi): 26.4 kg/m(2) (range: 15.8-45.3 kg/m(2))] receiving gc as part of cancer treatment. Mean total daily gc dose in the group was 238.5 mg (range: 30-1067 mg) hydrocortisone equivalents. Hyperglycemia (glucose ≥ 8.0 mmol/L) was found in 58.9% (53 of 90), and diabetes mellitus (dm)-range hyperglycemia (glucose ≥ 11.1 mmol/L) in 18.9% (17 of 90). The mean time from gc ingestion to glucometer testing was 5.5 hours (range: 3-20 hours). Presence of hyperglycemia did not correlate with traditional dm risk factors such as age, sex, bmi, and personal or family history of dm. A longer interval from gc dose to testing (p < 0.05), a higher gc dose (p = 0.04), and a shorter interval between the preceding meal and testing (p = 0.02) were risk factors for hyperglycemia in some patient groups. CONCLUSIONS Glucocorticoid-induced hyperglycemia is common in patients undergoing cancer treatment and cannot be predicted by traditional risk factors for dm. We recommend that all cancer patients receiving gc be screened for hyperglycemia at least 4-6 hours after gc administration.

Abstract
In recent years, the global incidence of Fasciola hepatica (liver fluke) infections exhibiting resistance to triclabendazole (TCBZ) has increased, resulting in increased economic losses for livestock producers and threatening future control. The development of TCBZ resistance and the worldwide discovery of F. hepatica population diversity has emphasized the need to further understand the genetic structure of drug susceptible and resistant Fasciola populations within Australia. In this study, the genetic diversity of liver flukes was estimated by sequencing mitochondrial DNA (mtDNA) encoding the NAD1 (530 bp) and COX1 (420 bp) genes of 208 liver flukes (F. hepatica) collected from three populations: field isolates obtained from abattoirs from New South Wales (NSW) and Victoria (Vic); three TCBZ-resistant fluke populations from NSW and Victoria; and the well-established TCBZ-susceptible Sunny Corner laboratory isolate. Overall nucleotide diversity for all flukes analysed of 0.00516 and 0.00336 was estimated for the NAD1 and COX1 genes respectively. Eighteen distinct haplotypes were established for the NAD1 gene and six haplotypes for the COX1 gene, resulting in haplotype diversity levels of 0.832 and 0.482, respectively. One field isolate showed a similar low level of haplotype diversity as seen in the Sunny Corner laboratory isolate. Analysis of TCBZ-resistant infrapopulations from 3 individual cattle grazing one property revealed considerable sequence parasite diversity between cattle. Analysis of parasite TCBZ-resistant infrapopulations from sheep and cattle revealed haplotypes unique to each host, but no significant difference between parasite populations. Fst analysis of fluke populations revealed little differentiation between the resistant and field populations. This study has revealed a high level of diversity in field and drug resistant flukes in South-Eastern Australia.

Abstract
BACKGROUND Penis cancer is rare and clinical trial evidence on which to base treatment decisions is limited. Case reports suggest that the combination of docetaxel, cisplatin and 5-flurouracil (TPF) is highly active in this disease. METHODS Twenty-nine patients with locally advanced or metastatic squamous carcinoma of the penis were recruited into a single-arm phase II trial from nine UK centres. Up to three cycles of chemotherapy were received (docetaxel 75 mg m(-2) day 1, cisplatin 60 mg m(-2) day 1, 5-flurouracil 750 mg m(-2) per day days 1-5, repeated every 3 weeks). Primary outcome was objective response (assessed by RECIST). Fourteen or more responses in 26 evaluable patients were required to confirm a response rate of 60% or higher (Fleming-A'Hern design), warranting further evaluation. Secondary endpoints included toxicity and survival. RESULTS 10/26 evaluable patients (38.5%, 95% CI: 20.2-59.4) achieved an objective response. Two patients with locally advanced disease achieved radiological complete remission. 65.5% of patients experienced at least one grade 3/4 adverse event. CONCLUSION Docetaxel, cisplatin and 5FU did not reach the pre-determined threshold for further research and caused significant toxicity. Our results do not support the routine use of TPF. The observed complete responses support further investigation of combination chemotherapy in the neoadjuvant setting.

Abstract
PURPOSE To investigate the prevalence of infected herniated nucleus material in lumbar disc herniations and to determine if patients with an anaerobic infected disc are more likely to develop Modic change (MC) (bone oedema) in the adjacent vertebrae after the disc herniation. MCs (bone oedema) in vertebrae are observed in 6 % of the general population and in 35-40 % of people with low back pain. These changes are strongly associated with low back pain. There are probably a mechanical cause and an infective cause that causes MC. Several studies on nuclear tissue from herniated discs have demonstrated the presence of low virulent anaerobic microorganisms, predominantly Propionibacterium acnes, in 7-53 % of patients. At the time of a herniation these low virulent anaerobic bacteria may enter the disc and give rise to an insidious infection. Local inflammation in the adjacent bone may be a secondary effect due to cytokine and propionic acid production. METHODS Patients undergoing primary surgery at a single spinal level for lumbar disc herniation with an MRI-confirmed lumbar disc herniation, where the annular fibres were penetrated by visible nuclear tissue, had the nucleus material removed. Stringent antiseptic sterile protocols were followed. RESULTS Sixty-one patients were included, mean age 46.4 years (SD 9.7), 27 % female. All patients were immunocompetent. No patient had received a previous epidural steroid injection or undergone previous back surgery. In total, microbiological cultures were positive in 28 (46 %) patients. Anaerobic cultures were positive in 26 (43 %) patients, and of these 4 (7 %) had dual microbial infections, containing both one aerobic and one anaerobic culture. No tissue specimens had more than two types of bacteria identified. Two (3 %) cultures only had aerobic bacteria isolated. In the discs with a nucleus with anaerobic bacteria, 80 % developed new MC in the vertebrae adjacent to the previous disc herniation. In contrast, none of those with aerobic bacteria and only 44 % of patients with negative cultures developed new MC. The association between an anaerobic culture and new MCs is highly statistically significant (P = 0.0038), with an odds ratio of 5.60 (95 % CI 1.51-21.95). CONCLUSION These findings support the theory that the occurrence of MCs Type 1 in the vertebrae adjacent to a previously herniated disc may be due to oedema surrounding an infected disc. The discs infected with anaerobic bacteria were more likely (P < 0.0038) to develop MCs in the adjacent vertebrae than those in which no bacteria were found or those in which aerobic bacteria were found.

Abstract
The HIV-1 genome enters cells inside a shell comprised of capsid (CA) protein. Variation in CA sequence alters HIV-1 infectivity and escape from host restriction factors. However, apart from the Cyclophilin A-binding loop, CA has no known interfaces with which to interact with cellular cofactors. Here we describe a novel protein-protein interface in the N-terminal domain of HIV-1 CA, determined by X-ray crystallography, which mediates both viral restriction and host cofactor dependence. The interface is highly conserved across lentiviruses and is accessible in the context of a hexameric lattice. Mutation of the interface prevents binding to and restriction by CPSF6-358, a truncated cytosolic form of the RNA processing factor, cleavage and polyadenylation specific factor 6 (CPSF6). Furthermore, mutations that prevent CPSF6 binding also relieve dependence on nuclear entry cofactors TNPO3 and RanBP2. These results suggest that the HIV-1 capsid mediates direct host cofactor interactions to facilitate viral infection.

Abstract
AIM To examine modifiable risk factors for anastomotic leak in patients undergoing low anterior resection. METHOD In total 233 patients undergoing low anterior resection for benign and malignant disease over a 10-year period at a single surgical unit were identified from a prospective database. The relationships between anastomotic leak and 17 variables were examined, including patient demographics, operative technique, tumour pathology, preoperative physiological function and smoking status. RESULTS The majority (91%) of operations were carried out for rectal cancers, and 24 procedures (10%) were performed with laparoscopic assistance. The overall anastomotic leak rate was 14% (33/233). Patients with anastomotic leak had higher 30-day mortality (6%vs 1%, P<0.05) and stayed significantly longer in hospital (median 23 vs 10 days, P<0.001). On multivariate analysis, current smokers (OR 3.68, 95% CI 1.38-9.82, P=0.009) and patients with evidence of metastatic malignant disease (OR 3.43, 95% CI 1.29-9.13, P=.013) were at increased risk of anastomotic leak. CONCLUSION Smoking and the presence of metastatic disease are major risk factors for the development of anastomotic leak following low anterior resection.

Abstract
The diagnosis of prosthetic joint infection and its differentiation from aseptic loosening remains problematic. The definitive laboratory diagnostic test is the recovery of identical infectious agents from multiple intraoperative tissue samples; however, interpretation of positive cultures is often complex as infection is frequently associated with low numbers of commensal microorganisms, in particular the coagulase-negative staphylococci (CNS). In this investigation, the value of serum procalcitonin (PCT), interleukin-6 (IL-6) and soluble intercellular adhesion molecule-1 (sICAM-1) as predictors of infection in revision hip replacement surgery is assessed. Furthermore, the diagnostic value of serum IgG to short-chain exocellular lipoteichoic acid (sce-LTA) is assessed in patients with infection due to CNS. Presurgical levels of conventional serum markers of infection including C-reactive protein (CRP), erythrocyte sedimentation rate (ESR) and white blood cell count (WBC) is also established. Forty-six patients undergoing revision hip surgery were recruited with a presumptive clinical diagnosis of either septic (16 patients) or aseptic loosening (30 patients). The diagnosis was confirmed microbiologically and levels of serum markers were determined. Serum levels of IL-6 and sICAM-1 were significantly raised in patients with septic loosening (P = 0.001 and P = 0.0002, respectively). Serum IgG to sce-LTA was elevated in three out of four patients with infection due to CNS. In contrast, PCT was not found to be of value in differentiating septic and aseptic loosening. Furthermore, CRP, ESR and WBC were significantly higher (P = 0.0001, P = 0.0001 and P = 0.003, respectively) in patients with septic loosening. Serum levels of IL-6, sICAM-1 and IgG to sce-LTA may provide additional information to facilitate the diagnosis of prosthetic joint infection.
