BackgroundUniversal anorectal testing for Chlamydia trachomatis (chlamydia) among women is not recommended in many countries, while anorectal chlamydia infections are common. Missed anorectal infections might cause sequelae at the genital site if autoinoculation from the anorectum is possible, but evidence is limited. This study investigates the association between potentially missed anorectal infections and subsequent genital chlamydia infections in women, using not being tested at the anorectal site as a proxy for having a potentially missed anorectal infection.MethodsWe included all women with a repeat chlamydia test within 1 year (with at least a genital test) from the Dutch sexual health centre surveillance between 2014 and 2019. Multilevel logistic regression analyses were used to identify determinants of genital chlamydia infection at the repeat test, with anorectal testing at the previous chlamydia test as the main determinant.ResultsA total of 40 217 women were included in the analyses, of whom 15.4% tested chlamydia-positive genitally at their second test. Not being tested anorectally at the first test was an independent risk factor for genital chlamydia infection at the repeat test (adjusted OR 1.24, 95% CI 1.15 to 1.33). This association was in the same range as most other significant risk factors in the model: low education level, no condom use, STI symptoms and previous STI diagnosis. Young age (<20 years) (2.67, 2.39–2.98) and those who received partner notification (3.11, 2.91–3.31) showed stronger associations. The findings were robust; correcting for interactions and a sensitivity analysis stratifying by chlamydia infection at first visit did not show significant differences in the adjusted OR of not being tested anorectally at first test.ConclusionThe results are suggestive of an autoinoculation process from the anorectal to the genital anatomical site in women. To enhance chlamydia control, future studies on the role of extragenital testing and autoinoculation in chlamydia transmission are needed.

Abstract Background Post-bariatric patients present a surgical challenge within abdominoplasty because of residual obesity and major comorbidities. In this study, we analyzed complications following abdominoplasty in post-bariatric patients and evaluated potential risk factors associated with these complications. Objectives The authors sought to determine the complications and risk factors following abdominoplasty in post-bariatric patients. Methods A retrospective study of patients who underwent abdominoplasty was performed from January 2009 to December 2018 at our institution. Variables analyzed were sex, age, body mass index (BMI), smoking, surgical technique, operative time, resection weight, drain output, and complications. Results A total of 406 patients were included in this study (320 female and 86 male) with a mean age of 44.4 years and a BMI of 30.6 kg/m2. Abdominoplasty techniques consisted of traditional (64.3%), fleur-de-lis technique (27.3%), and panniculectomy without umbilical displacement (8.4%). Overall complications recorded were 41.9%, the majority of these being wound-healing problems (32%). Minor and major complications were found in 29.1% and 12.8% of patients, respectively. A BMI value of ≥30 kg/m2 was associated with an increased risk for wound-healing problems (P = 0.001). The frequency of total complications was significantly related to age (P = 0.007), BMI (P = 0.004), and resection weight (P = 0.001). Abdominoplasty technique tended to influence total complications. Conclusions This study demonstrates in a fairly large sample of post-bariatric patients (n = 406) that abdominoplasty alone can be performed safely, with an acceptable complication rate. Age, BMI, and resection weight are shown to be significant risk factors for total complications. The role of surgical technique needs to be evaluated further. Level of Evidence: 4

ObjectiveChlamydia and gonorrhoea are common sexually transmitted infections that infect the oropharynx, anorectum and urethra in men who have sex with men (MSM). This study aimed to examine the pattern of infection at more than one site (multisite) for chlamydia and gonorrhoea among MSM.MethodsThis was a retrospective study of MSM attending the Melbourne Sexual Health Centre for the first time between 2018 and 2019. We included MSM aged ≥16 years who had tested for Neisseria gonorrhoeae and Chlamydia trachomatis at all three sites (oropharynx, anorectum and urethra). We compared infections that occurred at a single site (termed single-site infection) and those that occurred at more than one site (termed multisite infections).ResultsOf the 3938 men who were tested for chlamydia and gonorrhoea, 498/3938 men (12.6%, 95% CI 11.5% to 13.6%) had chlamydia at any site, of whom 400/498 (80.3%, 95% CI 78.9% to 81.2%) had single-site chlamydia infection, and 98/498 (19.7%, 95% CI 16.2% to 23.1%) had multisite infections. A similar proportion of men had gonorrhoea at any site (447/3938, 11.4%, 95% CI 10.3% to 12.2%), but among these 447 men, single-site infection was less common (256/447, 57.3%, 95% CI 52.6% to 61.7%, p<0.001) and multisite infection (191/447, 42.7%, 95% CI 38.2% to 47.3%, p<0.001) was more common than chlamydia. There were also marked differences by anatomical site. Urethral infection commonly occurred as single sites (75/122, 61.5%, 95% CI 52.8% to 70.1%) for chlamydia but uncommonly occurred for gonorrhoea (12/100, 12.0%, 95% CI 5.6% to 18.3%, p<0.001). In contrast, anorectal infection uncommonly occurred as multisite infection for chlamydia (98/394, 24.9%, 95% CI 20.6% to 29.1%) but was common (184/309, 59.5%, 95% CI 54.0% to 64.9%, p<0.001) for gonorrhoea.ConclusionsThe markedly different pattern of site-specific infection for chlamydia and gonorrhoea infections among the same MSM suggests significant differences in the transmissibility between anatomical sites and the duration of each infection at each site.

Introduction: Age and systolic blood pressure (SBP) are important predictors of Acute Cerebrovascular Syndrome (ACVS). Yet, the effect of SBP is confounded by age, making its independent contribution to ACVS risk difficult to quantify. Here we use logistic regression to explore the role of SBP in younger and older ED patients. Methods: Data comprised 1019 ED patients (ACVS 70%, 30% non-ACVS) enrolled during a 28-month period of an ongoing prospective, observational, multi-site stroke biomarker study (SpecTRA). We used logistic regression to examine the effects of age, sex, and the age:SBP interaction as predictive markers of the diagnosis of ACVS. Results: Participants (53% male) ranged in age from 18 to 97 years (Q1=58, median=70, Q3=80). SBP ranged from 84 to 248 mmHg (Q1=137, median=154, Q3=174). In our initial regression model, age, sex, SBP and the age:SBP interaction were all significant (p&lt;0.01). Using cubic regression splines for age, sbp and their interaction yields the same conclusion (p&lt;0.01). To better understand the role of SBP in younger vs. older patients, we stratified the sample at the median age (70 years of age). In the younger group (n=510), participants were 55% male, 60% ACVS, and had SBP ranging from 91 to 236 mmHg (Q1=133, median=148, Q3=165). In the older group (n=509), participants were 51% male, 82% ACVS and had SBP ranging from 84 to 248 mmHg (Q1=143, median=159, Q3=179), a shift of approximately 10 mmHg between the groups. The logistic regression model was then fit separately to each group without the age:SBP interaction term. In the younger group, we found SBP to be highly significant (p&lt;0.001), with an odds-ratio (OR) of 1.18 per 10 mmHg (95% CI: 1.10-1.29). In the older group, we found that SBP was not significant (p=0.91), with an OR of 1.00 per 10 mmHg (95% CI: 0.91-1.08). Age and sex were also significant risk factors in the younger group (each p&lt;0.01), though not in the older group (both p&gt;0.07). Conclusion: Our findings suggest that for ED patients suspected of ACVS, SBP is a clinically relevant predictor for younger patients, with higher SBP associated with an increased risk of ACVS, regardless of patient age and sex. SBP does not appear to be a strong predictor for patients over 70. ED physicians can leverage this finding by attributing greater importance to elevated SBP in younger patients than older patients when working toward a clinical suspicion of ACVS.

Migrants are at an increased risk of HIV acquisition. We aimed to use phylogenetics to characterize transmission clusters among newly-diagnosed asylum seekers and to understand the role of networks in local HIV transmission. Retrospective chart reviews of asylum seekers linked to HIV care between 1 June 2017 and 31 December 2018 at the McGill University Health Centre and the Jewish General Hospital in Montreal were performed. HIV-1 partial pol sequences were analyzed among study participants and individuals in the provincial genotyping database. Trees were reconstructed using MEGA10 neighbor-joining analysis. Clustering of linked viral sequences was based on a strong bootstrap support (>97%) and a short genetic distance (<0.01). Overall, 10,645 provincial sequences and 105 asylum seekers were included. A total of 13/105 participant sequences (12%; n = 7 males) formed part of eight clusters. Four clusters (two to three people) included only study participants (n = 9) and four clusters (two to three people) included four study participants clustered with six individuals from the provincial genotyping database. Six (75%) clusters were HIV subtype B. We identified the presence of HIV-1 phylogenetic clusters among asylum seekers and at a population-level. Our findings highlight the complementary role of cohort data and population-level genotypic surveillance to better characterize transmission clusters in Quebec.

Background. Transfusion-associated iron overload may increase the risk of infections both increasing bacterial or fungal growth and leading to the production of free iron that impairs immune system response. Anemia and transfusion dependency (TD) represent well known prognostic factors of survival in patients with myelofibrosis (MF). Compared to myelodysplastic syndrome (MDS), the role of iron overload on infection in MF has been scarcely explored. Methods. We identified consecutive adult patients diagnosed at our Centre with primary or secondary MF, between 1998 and 2018. Patients were stratified in 2 groups according to transfusion dependence defined as having received >2 unit of red blood cells (RBC) over 3 months. The total number of RBC units infused was also collected. All infections were recorded and graded according to Common Terminology Criteria for Adverse Events (CTCAE). Results. A total of 106 patients, median age 72 years (range 44-89) were retrospectively evaluated. A diagnosis of primary MF was performed in 75 of cases (71%), post Essential Thrombocythemia myelofibrosis (PET-MF) in 27 (25%) and post Polycythemia Vera myelofibrosis (PPV-MF) in 4 (4%). Splenomegaly was present in 83 patients (78%) and 30 (28%) reported constitutional symptoms.According to the IPSS, 43 patients (40 %) were classified at low or intermediate-1 risk, and 63 (60 %) at intermediate-2 or high risk. Molecular analysis was performed in 76 patients (72%): 54 of 76 patients (71%) were positive for the JAK2V617F mutation, 10 (13%) for CALR mutation, 4 (5%) for MPL, and 8 (11%) were negative for all tested mutations. Over time, 56 patients (53%) received hydroxyurea or other cytoreductive treatment, and 23 (22%) ruxolitinib. Overall, 39 patients (37%) were transfusion dependent with a median of 14 RBC units received during follow-up (range 4-199). The median serum ferritin level in the TD cohort was 840 ng/mL (range 130-12.129). Median observation time was 36 months (range 3-203). At last follow-up, 48 patients (45%) presented one or more infectious episodes. Total infectious events were 69 and 13 of them (19%) were defined as severe (grade 3-4 CTCAE). Anatomical site of infections was the respiratory tract in 28 (41%) of cases, gastro-intestinal in 22 (32%), gynecological-urological in 8 (11%), sepsis in 2 (3%), unspecified in the remaining cases. When detected, the etiological agents were bacterial in 8 (12%), viral in 5 (7%) and fungal in 4 (6%). The 60-month cumulative incidence of infection from diagnosis of MF was 64.1±6.5%. TD patients showed a higher incidence of infection (99±8.8% vs 53.3±8%, p=0.007) (Figure 1). In multivariate analysis no association was found between infection incidence and primary vs secondary MF, splenomegaly, age >65 years, ruxolitinib treatment; only transfusion dependencemaintained a significant association (p=0.019; HR=2.13; 95% C.I.=1.13-4.01). Among the 39 TD patients, the transfusion burden was significantly higher in those with infectious complication (median 24 RBC units vs 15 RBC units; p=0.012). The 60-month overall survival was 40±5.9%. Lower IPSS-risk (p<0.0001) and ruxolitinib treatment (p=0.027) were significantly associated with higher survival. Conclusions. This retrospective monocentric real-life study showed an increased risk of infections in MF patients with higher transfusion burden. The role of iron chelation in improving infection free survival in patients with MF and iron overload should be further investigated.

7543 Background: Certain non-Hodgkin lymphomas (NHL) such as primary mediastinal B-cell, Burkitt’s, and high-grade B-cell lymphoma with MYC and BCL2 rearrangements are often treated with infusional dose-adjusted rituximab, etoposide, prednisone, vincristine, cyclophosphamide and doxorubicin (DA-R-EPOCH), which requires a central line. We have observed meaningful line-associated complications (LAC) in patients (pts) treated with DA-R-EPOCH. With the ongoing use of this regimen, we sought to identify the rates and correlates of LAC in this population. Methods: We retrospectively identified all pts treated with DA-R-EPOCH at the Wilmot Cancer Institute between 3/2011 and 10/2015. Our primary endpoint was the rate of LAC, including venous thromboembolism (VTE), extravasation, and line-associated infection (LAI) diagnosed during DA-R-EPOCH therapy. Our secondary endpoint was the rate of VTE during therapy. Rates and 95% confidence intervals (95% CI) were calculated for all endpoints. Univariate logistic regression was used to calculate odds ratios to evaluate potential predictors. Results: 43 pts received DA-R-EPOCH during the study period. 70% of pts were male; median age was 52 years. 17 pts (39.5%, 95% CI 0.25 - 0.56) experienced at least 1 LAC: 15 pts (35%, 95% CI 0.21 - 0.51) had VTE; 3 pts had LAI; and 2 pts experienced extravasations. Grade 3 toxicity was seen in 41% (7/17): 4 pts with VTE, and 3 pts with LAI. Both extravasation events were grade 2, and both occurred with mediports. In univariate analysis, BMI ≥ 35 kg/m² and receiving therapy via peripherally inserted central catheter (PICC) line were significantly associated with an increased risk of VTE (p=0.04 and p=0.02, respectively). Conclusions: 40% of pts receiving DA-R-EPOCH therapy for treatment of NHL developed LAC, almost half of whom experienced grade 3 toxicities. Clinicians need to balance these risks when selecting therapy, particularly with the lack of randomized data to support the DA-R-EPOCH approach in many circumstances. Given observed extravasations, we avoid mediports in favor of PICC lines, however this approach carries a significant risk of VTE. Future studies are needed to evaluate the role of prophylactic anticoagulation in this population.

AbstractPreeclampsia complicates up to 8% of pregnancies and is a leading cause of fetomaternal morbidity andmortality. Treatment options are limited, with supportive care and delivery of the placenta representing the cornerstone of current management strategies. Derangements in blood coagulation are wellrecognised in this disorder and appear to favour an increased risk of venous thromboembolism among affected women. This risk appears to be most significant in the postpartum period. The mechanisms underlying this increased thrombosis risk remain to be fully elucidated although increased expression of procoagulant factors, endothelial dysfunction, attenuation of endogenous anticoagulant activity and increased platelet activity have been implicated in the prothrombotic tendency. Preeclampsia is also occasionally complicated by life-threatening haemorrhagic events and current evidence suggests that in some severe manifestations of this disease a coagulopathy with a clinical bleeding tendency may be the predominant haemostatic abnormality. Identifying affected women at significant risk of thrombosis and managing the competing thrombotic and haemorrhagic risks continue to be a significant clinical challenge. Derangements in blood coagulation are also implicated in the pathogenesis of preeclampsia; however, the role of antiplatelet or anticoagulant drugs in the prevention and treatment of this disorder remains a source of considerable debate. In addition, the potential role of specific haemostatic markers as diagnostic or screening tools for preeclampsia has also yet to be determined. Further characterisation of the underlying molecular mechanisms would likely be of major translational relevance and could provide insights into the pathogenesis of this disease as well as the associated haemostatic dysfunction.

Background: The maxillofacial structures are commonly affected in motorcycle crashes, with the mandible being one of the most frequently fractured bones. Helmets have been shown to have a protective effect in preventing maxillofacial inju- ries, however, its effect on the occurrence of mandibular fractures is not very well established. Objectives: To evaluate the pattern of mandibular fractures among motorcycle crash victims in Tanzania, and determine the role of helmets in occurrence of mandibular fractures among the motorcyclists. Methodology: This was a 6-months prospective, cross-sectional study that recruited motorcycle crash victims who reported with mandibular fractures following motorcycle crash at Muhimbili National Hospital. A specially designed questionnaire was used for data collection. For purpose of analysis, the Statistical Package for Social Sciences software version 20 was used. Results: The study included a total of 132 participants of whom majority were male (120, 90.9%). The peak age incidence was 21-40 years in 76.5% of the victims. More than half (89, 67.4%) of the victims were riders during the crash. Helmet use was reported in 42.3% of the victims, and majority (67.3%) were usinghalf-face helmets. The symphysis region was the fre- quently fractured anatomical location (50, 37.9%). More than half of the victims had multiple site involvement, with higher odds observed in individuals wearing half-face helmets. Conclusion: Young males were affected ten times more than females. Most of the victims were riders during the crash. The symphysis region was the frequently fractured anatomical site. There was no difference in occurrence of mandibular frac- tures between those who wore and those who did not wear helmets during the crashes. However, the severity of mandibular fractures was dependent on the type of helmet used. Keywords: Mandibular fracture; motorcycle crash; helmet use; Tanzania.

Psoriasis Severity

Background: IL-10 is an important pleiotropic, immunoregulatory and anti-inflammatory cytokine which plays a significant role in the pathogenesis of psoriasis. Objective: The aim of the present study was to determine whether the three polymorphic sites of the IL-10 gene, haplotype and serum level confer susceptibility to psoriasis. Method: 200 psoriatic patients and 200 controls were genotyped for three IL-10 polymorphic sites by ARMS polymerase chain reaction. Serum levels of IL -10 were measured by ELISA. Results: Our results demonstrated that polymorphism of IL-10 -592 C/A (adjusted* OR = 9.25; 95% CI =3.16- 27.06) and IL-10 1082 A/G (adjusted* OR = 4.28; (95% CI =1.46- 12.56) was found to be in association with increased risk of psoriasis while as IL- 10 819 C/T (adjusted* OR= 1.60; (95% CI = 0.65-3.95) polymorphism does not show any significant association with the risk of psoriasis. HT7 GTC haplotype is associated with increased risk of psoriasis. Serum levels of IL-10 were found to be significantly low in patients, as compared to controls with a non-significant correlation between serum IL-10 level and psoriasis severity. Conclusion: IL-10 polymorphism imparted significant risk towards the development of psoriasis in North Indian population. Highlighting the role of IL-10 cytokine in the pathogenesis of psoriasis will help in the development of psoriasis management.
