Abstract
OBJECTIVES Early mortality among those still initiating antiretroviral therapy (ART) with advanced stages of HIV infection in resource-limited settings remains high despite recommendations for universal HIV treatment. We investigated risk factors associated with early mortality in people living with HIV (PLHIV) starting ART at low CD4 levels in the Asia-Pacific. METHODS PLHIV enrolled in the Therapeutics, Research, Education and AIDS Training in Asia (TREAT Asia) HIV Observational Database (TAHOD) who initiated ART with a CD4 count < 100 cells/μL between 2003 and 2018 were included in the study. Early mortality was defined as death within 1 year of ART initiation. PLHIV in follow-up for > 1 year were censored at 12 months. Competing risk regression was used to analyse risk factors with loss to follow-up as a competing risk. RESULTS A total of 1813 PLHIV were included in the study, of whom 74% were male. With 73 (4%) deaths, the overall first-year mortality rate was 4.27 per 100 person-years (PY). Thirty-eight deaths (52%) were AIDS-related, 10 (14%) were immune reconstituted inflammatory syndrome (IRIS)-related, 13 (18%) were non-AIDS-related and 12 (16%) had an unknown cause. Risk factors included having a body mass index (BMI) < 18.5 [sub-hazard ratio (SHR) 2.91; 95% confidence interval (CI) 1.60-5.32] compared to BMI 18.5-24.9, and alanine aminotransferase (ALT) ≥ 5 times its upper limit of normal (ULN) (SHR 6.14; 95% CI 1.62-23.20) compared to ALT < 5 times its ULN. A higher CD4 count (51-100 cells/μL: SHR 0.28; 95% CI 0.14-0.55; and > 100 cells/μL: SHR 0.12; 95% CI 0.05-0.26) was associated with reduced hazard for mortality compared to CD4 count ≤ 25 cells/μL. CONCLUSIONS Fifty-two per cent of early deaths were AIDS-related. Efforts to initiate ART at CD4 counts > 50 cell/μL are associated with improved short-term survival rates, even in those with late stages of HIV disease.

Abstract
Background Estrogen receptor-positive (ER-positive) metastatic breast cancer is often intractable due to endocrine therapy resistance. Although ESR1 promoter switching events have been associated with endocrine-therapy resistance, recurrent ESR1 fusion proteins have yet to be identified in advanced breast cancer. Patients and methods To identify genomic structural rearrangements (REs) including gene fusions in acquired resistance, we undertook a multimodal sequencing effort in three breast cancer patient cohorts: (i) mate-pair and/or RNAseq in 6 patient-matched primary-metastatic tumors and 51 metastases, (ii) high coverage (>500×) comprehensive genomic profiling of 287-395 cancer-related genes across 9542 solid tumors (5216 from metastatic disease), and (iii) ultra-high coverage (>5000×) genomic profiling of 62 cancer-related genes in 254 ctDNA samples. In addition to traditional gene fusion detection methods (i.e. discordant reads, split reads), ESR1 REs were detected from targeted sequencing data by applying a novel algorithm (copyshift) that identifies major copy number shifts at rearrangement hotspots. Results We identify 88 ESR1 REs across 83 unique patients with direct confirmation of 9 ESR1 fusion proteins (including 2 via immunoblot). ESR1 REs are highly enriched in ER-positive, metastatic disease and co-occur with known ESR1 missense alterations, suggestive of polyclonal resistance. Importantly, all fusions result from a breakpoint in or near ESR1 intron 6 and therefore lack an intact ligand binding domain (LBD). In vitro characterization of three fusions reveals ligand-independence and hyperactivity dependent upon the 3' partner gene. Our lower-bound estimate of ESR1 fusions is at least 1% of metastatic solid breast cancers, the prevalence in ctDNA is at least 10× enriched. We postulate this enrichment may represent secondary resistance to more aggressive endocrine therapies applied to patients with ESR1 LBD missense alterations. Conclusions Collectively, these data indicate that N-terminal ESR1 fusions involving exons 6-7 are a recurrent driver of endocrine therapy resistance and are impervious to ER-targeted therapies.

Abstract
A multilaboratory study was conducted to compare the VIDAS®Listeria monocytogenes II (LMO2) immunoassay and the standard cultural methods for the detection of Listeria monocytogenes in foods. Five food types—vanilla ice cream, brie cheese, cooked roast beef, frozen green beans, and frozen tilapia fish—at 3 levels were analyzed by each method. A total of 26 laboratories representing government and industry participated. In this study, 1404 test portions were analyzed of which 1152 were used in the statistical analysis. There were 448 positive by the VIDAS LMO2 assay and 457 positive by the standard culture methods. A χ2 analysis of each of the 5 food types, at the 3 inoculation levels tested, was performed. The resulting χ2 value, 0.36, indicates that overall, there are no statistical differences between the VIDAS LMO2 assay and the standard methods at the 5% level of significance.

Abstract
Background Recognition of rare molecular subgroups is a challenge for precision oncology and may lead to tissue-agnostic approval of targeted agents. Here we aimed to comprehensively characterize the clinical, pathological and molecular landscape of RET rearranged metastatic colorectal cancer (mCRC). Patients and methods In this case series, we compared clinical, pathological and molecular characteristics of 24 RET rearranged mCRC patients with those of a control group of 291 patients with RET negative tumors. RET rearranged and RET negative mCRCs were retrieved by systematic literature review and by taking advantage of three screening sources: (i) Ignyta's phase 1/1b study on RXDX-105 (NCT01877811), (ii) cohorts screened at two Italian and one South Korean Institutions and (iii) Foundation Medicine Inc. database. Next-generation sequencing data were analyzed for RET rearranged cases. Results RET fusions were more frequent in older patients (median age of 66 versus 60 years, P = 0.052), with ECOG PS 1-2 (90% versus 50%, P = 0.02), right-sided (55% versus 32%, P = 0.013), previously unresected primary tumors (58% versus 21%, P < 0.001), RAS and BRAF wild-type (100% versus 40%, P < 0.001) and MSI-high (48% versus 7%, P < 0.001). Notably, 11 (26%) out of 43 patients with right-sided, RAS and BRAF wild-type tumors harbored a RET rearrangement. At a median follow-up of 45.8 months, patients with RET fusion-positive tumors showed a significantly worse OS when compared with RET-negative ones (median OS 14.0 versus 38.0 months, HR: 4.59; 95% CI, 3.64-32.66; P < 0.001). In the multivariable model, RET rearrangements were still associated with shorter OS (HR: 2.97; 95% CI, 1.25-7.07; P = 0.014), while primary tumor location, RAS and BRAF mutations and MSI status were not. Conclusions Though very rare, RET rearrangements define a new subtype of mCRC that shows poor prognosis with conventional treatments and is therefore worth of a specific management.

Abstract
OBJECTIVES Diabetes is a growing cause of morbidity and mortality in people living with HIV (PLHIV) receiving antiretroviral therapy (ART). We investigated the association between fasting plasma glucose (FPG) levels and mortality, and factors associated with FPG monitoring rates in Asia. METHODS Patients from the Therapeutics Research, Education, and AIDS Training in Asia (TREAT Asia) HIV Observational Database Low Intensity Transfer (TAHOD-LITE) cohort were included in the present study if they had initiated ART. Competing risk and Poisson regression were used to analyse the association between FPG and mortality, and assess risk factors for FPG monitoring rates, respectively. FPG was categorized as diabetes (FPG ≥ 7.0 mmol/L), prediabetes (FPG 5.6-6.9 mmol/L) and normal FPG (FPG < 5.6 mmol/L). RESULTS In total, 33 232 patients were included in the analysis. Throughout follow-up, 59% had no FPG test available. The incidence rate for diabetes was 13.7 per 1000 person-years in the 4649 patients with normal FPG at ART initiation. Prediabetes [sub-hazard ratio (sHR) 1.32; 95% confidence interval (CI) 1.07-1.64] and diabetes (sHR 1.90; 95% CI 1.52-2.38) were associated with mortality compared to those with normal FPG. FPG monitoring increased from 0.34 to 0.78 tests per person-year from 2012 to 2016 (P < 0.001). Male sex [incidence rate ratio (IRR) 1.08; 95% CI 1.03-1.12], age > 50 years (IRR 1.14; 95% CI 1.09-1.19) compared to ≤ 40 years, and CD4 count ≥ 500 cells/μL (IRR 1.04; 95% CI 1.00-1.09) compared to < 200 cells/μL were associated with increased FPG monitoring. CONCLUSIONS Diabetes and prediabetes were associated with mortality. FPG monitoring increased over time; however, less than half of our cohort had been tested. Greater resources should be allocated to FPG monitoring for early diabetic treatment and intervention and to optimize survival.

Abstract
Background Literature suggests that factors such as rural residence and low socioeconomic status (ses) might contribute to disparities in survival for Canadian cancer patients because of inequities in access to care. However, evidence specific to brain cancer is limited. The present research estimates the effects of rural or urban residence and ses on survival for Canadian patients diagnosed with brain cancer. Methods Adults diagnosed with primary malignant brain tumours during 1996-2008 were identified through the Canadian Cancer Registry. Brain tumours were classified using International Classification of Diseases for Oncology (3rd edition) site and histology codes. Hazard ratios (hrs) and 95% confidence intervals (cis) were estimated using Cox proportional hazards models. Events were restricted to individuals whose underlying cause of death was cancer-related. Postal codes were used to match patient records with Statistics Canada data for rural or urban residence and neighbourhood income as a surrogate measure of ses. Results Of 25,700 patients included in the analysis, 78% died during the study period, 21% lived in rural areas, and 19% were in the lowest income group. A modest variation in survival by rural compared with urban residence was observed for patients with glioblastoma (first 5 weeks after diagnosis hr: 0.86; 95% ci: 0.79 to 0.99) and oligoastrocytoma (first 3 years after diagnosis hr: 1.41; 95% ci: 1.03 to 1.93). Small effects of low compared with high income were seen for patients with glioblastoma (first 1.5 years after diagnosis hr: 1.15; 95% ci: 1.08 to 1.22) and diffuse astrocytoma (first 6 months after diagnosis hr: 1.17; 95% ci: 1.00 to 1.36). Conclusions Our analysis did not yield evidence of strong effects of rural compared with urban residence or ses strata on survival in brain cancer. However, some variation in survival for patients with specific histologies warrants further research into the mechanisms by which rural or urban residence and income stratum influences survival.

Abstract
Childhood adversities can impact negatively on psychological health across the lifespan. Many military veterans have a history of adverse childhood experiences, which when combined with deployment related traumas, can lead to high levels of psychopathology. Social networks can however be protective. The current study aimed to identify typologies of childhood adversity in U.S. military veterans (n = 3092) and explore relationships between the adversity typologies and PTSD, mood and anxiety disorders, utilising data from the National Epidemiological Survey on Alcohol and Related Conditions-III (NESARC-III). The mediating role of quality and quantity of social networks were examined. Latent class analysis identified four adversity classes; 1) baseline, 2) household dysfunction, 3) maltreatment, and 4) multi-adversity. Individuals in the adversity classes (2-4), especially those who experienced multi-adversity had higher rates of psychopathology. The quality of social networks played an important mediating role, while quantity of networks did not. Those who experienced adversity were less likely to have supportive social networks, therefore adversity had both a direct and indirect impact on psychopathology. The findings highlight the importance of developing and maintaining social networks following military life. Recommendations include interpersonal skills training and programmes which may help them engage back into the community and enhance relationships.

Abstract
OBJECTIVES With earlier antiretroviral therapy (ART) initiation, time spent in HIV care is expected to increase. We aimed to investigate loss to follow-up (LTFU) in Asian patients who remained in care 5 years after ART initiation. METHODS Long-term LTFU was defined as LTFU occurring after 5 years on ART. LTFU was defined as (1) patients not seen in the previous 12 months; and (2) patients not seen in the previous 6 months. Factors associated with LTFU were analysed using competing risk regression. RESULTS Under the 12-month definition, the LTFU rate was 2.0 per 100 person-years (PY) [95% confidence interval (CI) 1.8-2.2 among 4889 patients included in the study. LTFU was associated with age > 50 years [sub-hazard ratio (SHR) 1.64; 95% CI 1.17-2.31] compared with 31-40 years, viral load ≥ 1000 copies/mL (SHR 1.86; 95% CI 1.16-2.97) compared with viral load < 1000 copies/mL, and hepatitis C coinfection (SHR 1.48; 95% CI 1.06-2.05). LTFU was less likely to occur in females, in individuals with higher CD4 counts, in those with self-reported adherence ≥ 95%, and in those living in high-income countries. The 6-month LTFU definition produced an incidence rate of 3.2 per 100 PY (95% CI 2.9-3.4 and had similar associations but with greater risks of LTFU for ART initiation in later years (2006-2009: SHR 2.38; 95% CI 1.93-2.94; and 2010-2011: SHR 4.26; 95% CI 3.17-5.73) compared with 2003-2005. CONCLUSIONS The long-term LTFU rate in our cohort was low, with older age being associated with LTFU. The increased risk of LTFU with later years of ART initiation in the 6-month analysis, but not the 12-month analysis, implies that there was a possible move towards longer HIV clinic scheduling in Asia.

Abstract
SETTING Tuberculosis (TB) is the most common human immunodeficiency virus (HIV) related opportunistic infection and cause of acquired immune-deficiency syndrome related death. TB often affects those from a low socio-economic background. OBJECTIVE To assess the socio-economic determinants of TB in HIV-infected patients in Asia. DESIGN This was a matched case-control study. HIV-positive, TB-positive cases were matched to HIV-positive, TB-negative controls according to age, sex and CD4 cell count. A socio-economic questionnaire comprising 23 questions, including education level, employment, housing and substance use, was distributed. Socio-economic risk factors for TB were analysed using conditional logistic regression analysis. RESULTS A total of 340 patients (170 matched pairs) were recruited, with 262 (77.1%) matched for all three criteria. Pulmonary TB was the predominant type (n = 115, 67.6%). The main risk factor for TB was not having a university level education (OR 4.45, 95%CI 1.50-13.17, P = 0.007). Burning wood or coal regularly inside the house and living in the same place of origin were weakly associated with TB diagnosis. CONCLUSIONS These data suggest that lower socio-economic status is associated with an increased risk of TB in Asia. Integrating clinical and socio-economic factors into HIV treatment may help in the prevention of opportunistic infections and disease progression.

Abstract
Abstract
Objective: The established link between estrogen and breast cancer occurs via both estrogen receptor (ER)-mediated and non ER-mediated mechanisms. The term genotoxic estrogens describes mutagenic metabolites, including estrogen catechols and quinones, which have been linked to breast carcinogenesis in post-menopausal women. Recent data showed that childhood obesity is associated with significantly higher levels of genotoxic estrogens in the blood compared with lean children, raising the possibility of a potential pathogenic roles of these metabolites in breast cancer starting even prior to the onset of puberty (Mauras et al: J Clin Endocrinol Metab. 100:2322, 2015). A finding of higher levels of genotoxic estrogens associated with oral estradiol may have breast cancer prevention implications.We hence aimed to assess if the route of administration of 17β estradiol (E2) affects the accumulation of genotoxic estrogen metabolites in a model of ovarian failure in young girls with Turner Syndrome.
Methods: Stored plasma were used from 40 adolescents with Turner's who participated in a previous 12 months randomized controlled trial of the metabolic impact of E2 orally (2mg/d) vs. transdermally (100μg/d). The doses of oral and transdermal E2 were determined to result in similar plasma levels of unconjugated E2. Previously we had reported that despite the similar plasma levels of unconjugated E2, the oral E2 administration route was associated with higher levels of biologically active estrogen activity than the transdermal route (Torres-Santiago L et al:J Clin Endocrinol Metab. 98:2716, 2013). In this study, we measured 12 estrogen metabolites (conjugated and unconjugated) using a highly sensitive LCMSMS assay. Results from 48 normally menstruating adolescents were used for comparison.
Results: After treatment, least square mean (SE) total (conjugated plus unconjugated) E2 and estrone (E1) concentrations were higher in the oral vs. transdermal group (p<0·0001), as were catechol-estrogens 4-OH-E2 (149 vs. 28 (49) pmol/L), 2-OH-E2 (300 vs 76 (52)), 4-OH-E1 (450 vs 105 (113)), 2-OH-E1 (304 vs 740 (684)) and 16α-OH-E1 (3007 vs 157 (534)) (<0·001 between groups). Levels were much closer to controls in the transdermal group.
Conclusions: Common feminizing doses of oral estradiol for 12 months result in greater accumulation of unphysiologic, genotoxic estrogens than transdermal estradiol, expanding concerns about oral estrogens' first hepatic passage contributing to the accumulation of these metabolites. These metabolites have the potential for inducing breast cancer in post-menopausal women. These results suggest the potential benefit of preferential use of transdermal versus oral estrogens as replacement and possibly contraceptive options, in the prevention of breast cancer. Further studies to assess long-term risks of these metabolites in women taking different forms of estrogen replacement are needed.

Abstract
Abstract
Background
The recent approval of PARP inhibitor, olaparib, in HER2-negative breast cancer expands the therapeutic options for patients with germline BRCA1/2 alterations. The role of somatic BRCA alteration as a predictive biomarker in breast cancer is currently unclear. NCCN guidelines call for germline testing in all young patients (<46 yrs) and patients with triple negative breast cancer (TNBC) (< 61 yrs) with a personal history of breast cancer. Here we examined the landscape of BRCA mutations to assess whether additional populations may have potential benefit from PARP inhibitors.
Methods
Hybrid-capture based comprehensive genomic profiling of 395 cancer-related genes using the FoundationOne assay (Foundation Medicine, MA) was performed on 12,508 breast carcinomas. Somatic/germline/zygosity status for BRCA1/2 variants was analyzed as described in Sun, 2018 (PMID: 29415044). High genome-wide loss-of-heterozygosity (gLOH) was classified as ≥16% LOH. Subgroups were analyzed on histological {Invasive Ductal Carcinoma (IDC), Invasive Lobular Carcinoma (ILC)} and molecular subtypes [ER-positive (ER+), HER2-amplified (HER2+), TNBC], patient age [≤45, 46-60, 61+], and gender.
Results
Consistent with previous reports, the frequency of BRCA1/2 alterations was highest in young patients (<46; 15%), TNBC (10%), and male breast cancer (14%); BRCA1/2 alterations were also identified in HER2+, ILC, and ER+ tumors (5.3%, 6.5%, 8.3%). Overall, BRCA1 was more frequently mutated in TNBC and young patients (67%), whereas BRCA2 was more frequently mutated in ER+, HER2+, ILC, and male breast cancer (63%, 57%, 79%, 100%).
The fraction of somatic BRCA mutations (sBRCA) was 38%, with the lowest fraction of sBRCA in TNBC and young patients (30%, 30% overall, 36%, 42% for BRCA1) and highest in HER2+, ILC, and older patients (46%, 52%, 51%); the absolute frequency of sBRCA is approximately 3.5%. In tumors with ESR1 mutations, we detected concurrent BRCA mutation in 6.4% (85/1319), with 48% predicted somatic.
Almost all tumors with BRCA mutations had biallelic inactivation, with LOH of the second allele irrespective of predicted germline status (90% of gBRCA and 86% of sBRCA under LOH). gLOH score was used as a phenotypic measure of homologous recombination deficiency (HRD): patients harboring biallelic BRCA alterations had elevated rates of gLOH with 89% of gBRCA and 84% of sBRCA tumors harboring a high gLOH score, vs 47% with heterozygous BRCA, 34% with no BRCA alteration, and 80% for patients with BRCA deletion.
Conclusions
Thirty-eight percent of deleterious BRCA alterations in breast are predicted somatic, including 36% of BRCA1 alterations in TNBC. Germline testing would miss these alterations even though they are frequently under LOH and are associated with high gLOH, a biomarker with predictive value in ovarian cancer. While patients with ER+ and HER2+ tumors have low rates of gBRCA alterations, the overall BRCA mutation rate, including somatic alterations, is appreciable at 8.3% and 5.3%. Our findings demonstrate that sBRCA alterations are associated with a comparable HRD phenotype to gBRCA altertions and suggests that PARP inhibitors may have potential value for a wider range of breast cancer patients.

Abstract
OBJECTIVES With aging of the HIV-positive population, cardiovascular disease (CVD) increasingly contributes to morbidity and mortality. We investigated CVD-related and other causes of death (CODs) and factors associated with CVD in a multi-country Asian HIV-positive cohort. METHODS Patient data from 2003-2017 were obtained from the Therapeutics, Research, Education and AIDS Training in Asia (TREAT Asia) HIV Observational Database (TAHOD). We included patients on antiretroviral therapy (ART) with > 1 day of follow-up. Cumulative incidences were plotted for CVD-related, AIDS-related, non-AIDS-related, and unknown CODs, and any CVD (i.e. fatal and nonfatal). Competing risk regression was used to assess risk factors of any CVD. RESULTS Of 8069 patients with a median follow-up of 7.3 years [interquartile range (IQR) 4.4-10.7 years], 378 patients died [incidence rate (IR) 6.2 per 1000 person-years (PY)], and this total included 22 CVD-related deaths (IR 0.36 per 1000 PY). Factors significantly associated with any CVD event (IR 2.2 per 1000 PY) were older age [sub-hazard ratio (sHR) 2.21; 95% confidence interval (CI) 1.36-3.58 for age 41-50 years; sHR 5.52; 95% CI 3.43-8.91 for ≥ 51 years, compared with < 40 years], high blood pressure (sHR 1.62; 95% CI 1.04-2.52), high total cholesterol (sHR 1.89; 95% CI 1.27-2.82), high triglycerides (sHR 1.55; 95% CI 1.02-2.37) and high body mass index (BMI) (sHR 1.66; 95% CI 1.12-2.46). CVD crude IRs were lower in the later ART initiation period and in lower middle- and upper middle-income countries. CONCLUSIONS The development of fatal and nonfatal CVD events in our cohort was associated with older age, and treatable risk factors such as high blood pressure, triglycerides, total cholesterol and BMI. Lower CVD event rates in middle-income countries may indicate under-diagnosis of CVD in Asian-Pacific resource-limited settings.

Abstract
Background: Significant numbers of individuals leave the military and experience symptoms of posttraumatic stress disorder (PTSD). Veterans with PTSD symptoms rarely experience them in isolation, more commonly they are co-morbid with a range of other difficulties. Objective: Latent profile analysis (LPA) was used to explore the heterogeneity of PTSD symptom presentation. Following this, regression analysis was used to examine variables that predicted membership to the identified PTSD profiles. Methods: Data on childhood adversity, socio-demographic characteristics and mental health outcomes was collected from 386 male veterans who had engaged with mental health services in the UK. Results: LPA identified a six-profile model to best describe the sample. There was a Low symptom profile, a Severe symptom profile and four Moderate symptom profiles. The Severe symptom profile was the largest one, accounting for 37.57% of the sample. Five out of the six profiles had mean PTSD scores above the cut-off for probable PTSD. Higher rates of common mental health difficulties were associated with more symptomatic profiles. Discussion: As the vast majority of veterans met criteria for probable PTSD, the finding of six different profiles differing primarily quantitatively, but to some extent also qualitatively, suggests the importance of moving away from a 'one-size fits all' approach when it comes to treatments, towards developing interventions that are tailored to meet the specific PTSD and co-morbid symptoms profiles.

Abstract
BACKGROUND Parental inability to recognize child overweight and physician reluctance to instigate discussion prevents behaviour change. OBJECTIVE To evaluate parental acceptance of child overweight status following screening. METHODS Interviewers used motivational interviewing or best practice care to discuss overweight status of 271 young children (BMI ≥ 85th ) with parents using simple traffic-light BMI charts. Follow-up sessions two weeks later (n = 251, 93%) were coded qualitatively to assess parental reactions to the information (overweight diagnosis) and how it was presented (feedback condition). RESULTS Eight-two percent of parents rated the charts positively with few (8-10%) feeling judged. Motivational interviewing parents viewed feedback as more empathetic (relative risk, 95% CI: 4.07, 1.64-10.09), but more uncomfortable (12.2, 1.48-100.1) than best practice care parents. Overall, 65.2% of parents accepted their child was overweight, 22.1% were ambivalent and 12.7% rejected the information. Although motivational interviewing parents were less likely to accept it (OR, 95% CI: 0.49, 0.37-0.64) and more likely to be ambivalent (2.01, 1.17-3.47), the most important predictor of acceptance was a positive experience of feedback (P < 0.001). CONCLUSIONS Simple traffic-light charts facilitate discussion of child overweight status with parents. Style of feedback is less relevant than ensuring a positive experience for parents to increase acceptance of the weight information.

Abstract
BACKGROUND AND PURPOSE Coccidioides immitis is a dimorphic fungus endemic to the Southwest United States and Mexico, and at our institution, it is a relatively common pathogen presenting with a broad spectrum of associated spine diseases. We describe the various spinal manifestations resulting from coccidioidal infection and provide MR imaging examples from 41 pathologically proved cases. MATERIALS AND METHODS Retrospective electronic medical record and PACS searches were performed. Patients found to have both MR imaging findings positive for infection and confirmative biopsy and/or CSF studies were included. Abnormal MR imaging findings were identified, categorized, and quantified. Patient demographics and associated intracranial involvement if present were also recorded. RESULTS Forty-one patients were included. Positive findings were categorized as leptomeningeal enhancement (26 patients, 63%), arachnoiditis (22 patients, 54%), osteomyelitis-discitis (14 patients, 34%), cord edema (11 patients, 27%), and true syrinx (3 patients, 7%). Thirty patients had documented brain involvement (73%), most commonly in the form of basilar meningitis. Four patients were positive for HIV (10%). Fifteen patients had pulmonary manifestations at presentation (37%). CONCLUSIONS C immitis results in various spinal manifestations, most commonly leptomeningeal enhancement and arachnoiditis/adhesive disease followed by osteomyelitis, which may resemble tuberculous or pyogenic infection on MR imaging.

Abstract
The latent structure of posttraumatic stress disorder (PTSD) has been widely discussed, with the majority of studies in this area being conducted in the US. The current study aimed to extend this area of research by comparing seven existing PTSD factor models in a sample of 754 trauma-exposed university students from Slovakia, where similar research has not been conducted yet. The sample was predominantly female (83.69%), with a mean age of 22.68 years. The comparison of competing models revealed that the Anhedonia model, consisting of six inter-correlated factors of reexperiencing, avoidance, negative affect, anhedonia, dysphoric arousal and anxious arousal, provided the best fit. Several factors of the Anhedonia model also showed differential relationships with the external variables of anxiety and depression. The study contributes to the limited literature on the latent structure of PTSD in Eastern Europe.

Abstract
OBJECTIVE To estimate the incidence of caesarean scar pregnancy (CSP) and to describe the management outcomes associated with this condition. DESIGN A national cohort study using the UK Early Pregnancy Surveillance Service (UKEPSS). SETTING 86 participating Early Pregnancy Units. POPULATION All women diagnosed in the participating units with CSP between November 2013 and January 2015. METHODS Cohort study of women identified through the UKEPSS monthly mailing system. MAIN OUTCOME MEASURES Incidence, clinical outcomes and complications. RESULTS 102 cases of CSP were reported, with an estimated incidence of 1.5 per 10 000 (95% CI 1.1-1.9) maternities. Full outcome data were available for 92 women. Management was expectant in 21/92 (23%), medical in 15/92 (16%) and surgical in 56/92 (61%). The success rates of expectant, medical and surgical management were 43% (9/21), 46% (7/15) and 96% (54/56), respectively. The complication rates were 15/21 (71%) with expectant, 9/15 (60%) with medical and 20/56 (36%) with surgical management. Discharge from care (median number of days) was 82 (range 37-174) with expectant, 21 (range 10-31) with medical and 11 (range 4-49) with surgical management. CONCLUSIONS Surgical management appears to be associated with a high success rate, low complication rate and short post-treatment follow up. TWEETABLE ABSTRACT Surgery for CSP appears to be successful, with low complication rates and short post-treatment follow up.

Abstract
Network analysis is a relatively new methodology for studying psychological disorders. It focuses on the associations between individual symptoms which are hypothesized to mutually interact with each other. The current study represents the first network analysis conducted with treatment-seeking military veterans in UK. The study aimed to examine the network structure of posttraumatic stress disorder (PTSD) symptoms and four domains of functional impairment by identifying the most central (i.e., important) symptoms of PTSD and by identifying those symptoms of PTSD that are related to functional impairment. Participants were 331 military veterans with probable PTSD. In the first step, a network of PTSD symptoms based on the PTSD Checklist for DSM-5 was estimated. In the second step, functional impairment items were added to the network. The most central symptoms of PTSD were recurrent thoughts, nightmares, negative emotional state, detachment and exaggerated startle response. Functional impairment was related to a number of different PTSD symptoms. Impairments in close relationships were associated primarily with the negative alterations in cognitions and mood symptoms and impairments in home management were associated primarily with the reexperiencing symptoms. The results are discussed in relation to previous PTSD network studies and include implications for clinical practice.

CHILD ABUSE & NEGLECT 2018; 79:74-84.

Abstract
Numerous studies have reported that adverse childhood experiences (ACEs) are associated with negative psychosocial outcomes in adulthood, but no study has examined the different typologies of ACEs and the relationship of these with adult incarceration in military veterans. The current study used latent class analysis to examine the existence of different childhood maltreatment and household dysfunction typologies in a sample of U.S. military veterans identified through the National Epidemiological Survey on Alcohol and Related Conditions-III ((NESARC-III)). A total of 60.73% of veterans reported one or more ACEs. Four latent classes were identified and were named Low adversities, Moderate maltreatment with high household substance use, Severe maltreatment with moderate household dysfunction and Severe multi-type adversities. Relative to the Low adversities class, the three maltreatment/dysfunction classes had significantly elevated odds ratios (1.72-2.29) for adult incarceration, when controlling for sociodemographic characteristics and alcohol and drug use. The results point to the importance of examining childhood risk factors for incarceration and suggest that a certain sub-group of military personnel who are about to transition into the civilian life may need additional support to adjust and live successful lives.

Abstract
PURPOSE Studies conducted in the USA, Canada and Denmark have supported the existence of the dissociative PTSD subtype, characterized primarily by symptoms of depersonalization and derealization. The current study aimed to examine the dissociative PTSD subtype in an Eastern European, predominantly female (83.16%) sample, using an extended set of dissociative symptoms. METHODS A latent profile analysis was applied to the PTSD and dissociation data from 689 trauma-exposed university students from Slovakia. RESULTS Four latent profiles of varying PTSD and dissociation symptomatology were uncovered. They were named non-symptomatic, moderate PTSD, high PTSD and dissociative PTSD. The dissociative PTSD profile showed elevations on depersonalization and derealization, but also the alternative dissociative indicators of gaps in awareness and memory, sensory misperceptions and cognitive and behavioural re-experiencing. The core PTSD symptoms of 'memory impairment' and 'reckless or self-destructive behaviour' were also significantly elevated in the dissociative PTSD profile. Moreover, anxiety and anger predicted membership in the dissociative PTSD profile. CONCLUSION The results provide support for the proposal that the dissociative PTSD subtype can be characterized by a variety of dissociative symptoms.
