Abstract
BACKGROUND AND OBJECTIVES Despite effective combination antiretroviral therapy (cART), adolescents with perinatally acquired HIV (PHIV) exhibit cognitive impairment, of which structural changes could be the underlying pathophysiologic mechanism. Prior MRI studies found lower brain volumes, higher white matter (WM) hyperintensity (WMH) volume, lower WM integrity, and differences in cerebral blood flow (CBF). However, these findings may be confounded by adoption status, as a large portion of adolescents with PHIV have been adopted. Adoption has been associated with malnutrition and neglect, which, in turn, may have affected brain development. We investigated the long-term effects of PHIV on the brain, while minimizing the confounding effect of adoption status. METHODS We determined whole-brain gray matter (GM) and WM volume with 3D T1-weighted scans; total WMH volume with fluid-attenuated inversion recovery; CBF in the following regions of interest (ROIs): WM, GM, and subcortical GM with arterial spin labeling; and whole-brain WM microstructural markers: fractional anisotropy (FA), mean diffusivity (MD), axial diffusivity (AD), and radial diffusivity (RD) with diffusion tensor imaging in cART-treated adolescents with PHIV visiting our outpatient clinic in Amsterdam and controls matched for age, sex, ethnic origin, socioeconomic status, and adoption status. We assessed differences in neuroimaging parameters between adolescents with PHIV and controls using linear regression models adjusted for age and sex and applied multiple comparison correction. RESULTS Thirty-five adolescents with PHIV and 38 controls were included with a median age of 14.9 (interquartile range [IQR]: 10.7-18.5) and 15.6 (IQR: 11.1-17.6) years, respectively, with a similar rate of adoption. We found a lower overall FA (beta = -0.012; p < 0.014, -2.4%), a higher MD (beta = 0.014, p = 0.014, 1.3%), and a higher RD (beta = 0.02, p = 0.014, 3.3%) in adolescents with PHIV vs adoption-matched controls, but no differences in AD. We found comparable GM, WM, and WMH volume and CBF in ROIs between adolescents with PHIV and controls. We did not find an association between cognitive profiles and WM microstructural markers in adolescents with PHIV. DISCUSSION Irrespective of adoption status, adolescents with PHIV exhibited subtle lower WM integrity. Our findings may point toward early-acquired WM microstructural alterations associated with HIV.

Abstract
Most flavors used in e-liquids are generally recognized as safe for oral consumption, but their potential effects when inhaled are not well characterized. In vivo inhalation studies of flavor ingredients in e-liquids are scarce. A structure-based grouping approach was used to select 38 flavor group representatives (FGR) on the basis of known and in silico-predicted toxicological data. These FGRs were combined to create prototype e-liquid formulations and tested against cigarette smoke (CS) in a 5-week inhalation study. Female A/J mice were whole-body exposed for 6 h/day, 5 days/week, for 5 weeks to air, mainstream CS, or aerosols from (1) test formulations containing propylene glycol (PG), vegetable glycerol (VG), nicotine (N; 2% w/w), and flavor (F) mixtures at low (4.6% w/w), medium (9.3% w/w), or high (18.6% w/w) concentration or (2) base formulation (PG/VG/N). Male A/J mice were exposed to air, PG/VG/N, or PG/VG/N/F-high under the same exposure regimen. There were no significant mortality or in-life clinical findings in the treatment groups, with only transient weight loss during the early exposure adaptation period. While exposure to flavor aerosols did not cause notable lung inflammation, it caused only minimal adaptive changes in the larynx and nasal epithelia. In contrast, exposure to CS resulted in lung inflammation and moderate-to-severe changes in the epithelia of the nose, larynx, and trachea. In summary, the study evaluates an approach for assessing the inhalation toxicity potential of flavor mixtures, thereby informing the selection of flavor exposure concentrations (up to 18.6%) for a future chronic inhalation study.

Abstract
Splenic artery pseudoaneurysm is a rare entity. Clinical diagnosis is challenging because presentation is often varied. It can range from an incidental finding to hemodynamic collapse from sudden rupture and bleeding. The most common cause of this condition is pancreatitis. We report an unusual case of a young man not known to have pancreatitis who presented with hematemesis with normal esophagogastroduodenoscopy. Imaging modalities did not lead to a definitive diagnosis, and he underwent emergency laparotomy with surgical ligation of splenic artery pseudoaneurysm for hemodynamic instability, without a definitive preoperative diagnosis.

Abstract
AIM To determine diagnostic rate, complications and patient tolerability of endobronchial ultrasound-guide sheath (EBUS-GS) and computed tomography (CT)-guided percutaneous core biopsy for peripheral lung lesions. METHODS Lesions >1 cm diameter on CT were randomised to either EBUS-GS or CT-guided biopsy. Excluded were patients with severe chronic obstructive airway disease, lesions touching visceral pleura or hilum, and patients with symptoms needing bronchoscopic evaluation. Patients completed preprocedure and postprocedure questionnaires on tolerability. RESULTS Of 64 participants (mean lesion size 29 ± 16 mm), 57 completed the study. Diagnostic sensitivity was 67% for EBUS-GS and 78% for CT-guided biopsy (P = not significant). In those with negative results, in the EBUS group, nine had a CT-guided biopsy as a cross-over, seven of which were positive. In the CT group, four had cross-over EBUS-GS of which three were diagnostic. Sensitivity for malignancy was 17/23 for EBUS-GS (74%) and 23/26 (88%, P = not significant). For lesions <2 cm, CT-guided biopsy had a significantly better diagnostic yield (80% vs 50%, P = 0.05). In EBUS-GS cases, for lesions with an air bronchogram, sensitivity was 89%. Pneumothorax and intercostal catheter insertion occurred in three and two cases, respectively, for EBUS, and 10 and 3 cases for CT-guided biopsy (P = 0.02 for pneumothorax). Nine unexpected admissions occurred after CT-guided biopsy compared with three after EBUS-GS. Overall, tolerability was high for both groups; however three patients had moderate-to-severe pain after CT-guided biopsy. CONCLUSIONS In lesions <2 cm, CT-guided biopsy had higher yields; however, EBUS-GS had better tolerability and fewer complications.

Abstract
6509 Background: Despite high rates of clinical responses to IM, molecular complete responses are rare. The curative potential of allo transplantation and donor lymphocyte infusions underscores CML’s responsiveness to T cell mediated immunity. K562/GM-CSF is a tumor vaccine derived from a CML cell line that expresses several defined CML associated antigens and has been genetically engineered to produce GM-CSF. A pilot vaccination strategy was developed to determine if K562/GM-CSF immunotherapy in combination with IM could enhance T cell reactivity and clinical responses in pts having persistent, measurable disease despite 1 or more years on IM. Methods: Eligibility required pts to have achieved a major cytogenetic response (<35% Ph+ cells) while on a stable dose of IM. Disease burden was measured serially over 12 wks prior to vaccines. 4 vaccines were administered in 3 wk intervals, each consisting of 1 × 108 irradiated K562/GM-CSF cells distributed over 10 sites, with or without topical 5% Aldara (a Toll-like receptor 7 agonist) used as a vaccine adjuvant. Disease burden was measured at 6 wk intervals for 9 mos from the first vaccine and specimens were banked for measurement of immune responses. Results: The trial enrolled 19 pts, all have completed the planned 4 vaccinations and 14 pts have completed all planned disease burden measurements. The median age is 52 (range 28–76) yrs with a median time from dx to enrollment of 57 (range 16–111) mos. Pts were on IM for a median of 37 (13–53) mos prior. 4 of 19 pts had FISH pos as their best previous response (BPR) with 2 becoming FISH neg post-vaccine (1 became PCR neg and 1 achieved a >1 log reduction in disease burden by PCR). Of the 15 pts whose BPR was FISH neg/PCR pos, 4 are now PCR neg post vaccine, 4 experienced a >1 log and 1 had 0.5–0.99 log reduction by PCR. Mean PCR levels for the 19 pts declined btwn pre- and post-vaccine measures (p=0.01). 3 of 5 pts achieving PCR neg remain so beyond 6 months. Only 1 pt progressed having entered the study with a heavy disease burden (30% FISH pos). Conclusions: K562/GM-CSF vaccine appears to improve responses in pts on IM, including achieving complete molecular remissions, despite long durations of previous IM therapy. [Table: see text]
