Abstract
Abstract
Background
The REPLACE study investigated the effect of switching to riociguat (RIO) in patients with pulmonary arterial hypertension receiving PDE5i but still at intermediate risk. The centrally adjudicated composite primary endpoint was clinical improvement in the absence of clinical worsening, where clinical improvement was defined as meeting at least two of the following criteria: 6-minute walk distance (6MWD), increase by ≥10% or ≥30 m from baseline (BL) to Wk 24; World Health Organization functional class (WHO FC) I or II at Wk 24; or N-terminal prohormone of brain natriuretic peptide reduction of ≥30% from BL to Wk 24. Twice as many patients switching to RIO (45/111, 41%) met the primary endpoint compared with those remaining on PDE5i (23/113, 20%); odds ratio (OR): 2.78 (95% confidence interval [CI] 1.53–5.06); p=0.0007.
Purpose
Assess changes in right and left ventricular (RV; LV) function using cardiac magnetic resonance imaging (cMRI) in a subgroup of patients participating in REPLACE.
Methods
REPLACE was a randomised, open-label, 24-week, Phase 4 study (NCT02891850). Patients in WHO FC III, with 6MWD 165–440 m, were randomised to switch to RIO 2.5 mg–max tid or remain on PDE5i. Background endothelin receptor antagonist therapy was permitted in both arms.
cMRI was performed on a subset of patients from the full analysis set as an exploratory substudy. The following parameters were measured at BL and Wk 24: RV and LV end-diastolic and end-systolic volumes (RVEDV; RVESV; LVEDV; LVESV), RV stroke volume and stroke volume index (RVSV; RVSVI), LV stroke volume (LVSV), RV ejection fraction (RVEF), and pericardial effusion.
Results
Twenty-seven patients participated in the cMRI substudy. This comprised 11/111 (10%) patients in the RIO arm (mean [standard deviation {SD}] 40.0 [12.4] years), and 16/113 (14%) patients (mean 44.5 [17.6] years) in the PDE5i arm. Like the main population, the treatment response in the cMRI subpopulation favoured RIO versus PDE5i (OR: 6.11 [95% CI 0.90–41.60]). From BL to Wk 24, RVEDV and RVESV decreased in the RIO treatment arm but increased in the PDE5i treatment arm (Table 1). Similar, but less pronounced, changes were observed for the left ventricle (LVESV, LVEDV). RVSV and RVEF levels were close to normal at BL and did not increase in either arm at Wk 24 (Table 1). Pericardial effusion, which was present in 5 patients in each group at BL, decreased in 1 patient in the RIO arm and no patients in the PDE5i arm.
Conclusions
Decreases in RVEDV and RVESV suggest improvements in cardiac function in the RIO arm compared with the PDE5i arm. Values for RVEF and RVSVI were close to normal at BL and did not change at Wk 24. Improvements in cMRI parameters were in line with the clinical improvement observed in patients switching to RIO in the overall population.

Abstract
BACKGROUND Overdose is a major cause of morbidity and mortality among people who use opioids. Naloxone can reverse opioid overdoses and can be distributed and administered with minimal training. People with experience of overdose are a key population to target for overdose prevention strategies. This study aims to understand if factors associated with recent non-fatal opioid overdose are the same as factors associated with naloxone access and naloxone training in people who recently used opioids or received opioid agonist treatment (OAT). METHODS ETHOS Engage is an observational study of people who inject drugs in Australia. Logistic regression models were used to estimate odds ratios for non-fatal opioid overdose, naloxone access and naloxone training. RESULTS Between May 2018-September 2019, 1280 participants who recently used opioids or received OAT were enrolled (62% aged >40 years; 35% female, 80% receiving OAT, 62% injected drugs in the preceding month). Recent opioid overdose (preceding 12 months) was reported by 7% of participants, lifetime naloxone access by 17%, and lifetime naloxone training by 14%. Compared to people receiving OAT with no additional opioid use, recent opioid, benzodiazepine (preceding six months), and hazardous alcohol use was associated with recent opioid overdose (aOR 3.91; 95%CI: 1.68-9.10) and lifetime naloxone access (aOR 2.12; 95%CI 1.29-3.48). Among 91 people who reported recent overdose, 65% had never received take-home naloxone or naloxone training. CONCLUSIONS Among people recently using opioids or receiving OAT, benzodiazepine and hazardous alcohol use is associated with non-fatal opioid overdose. Not all factors associated with non-fatal overdose correspond to factors associated with naloxone access. Naloxone access and training is low across all groups. Additional interventions are needed to scale up naloxone provision.

Abstract
Abstract
Introduction
PAH impacts right ventricular (RV) structure and function but also leads to changes in the LV due to RV/LV interaction and underfilling. REPAIR, the first PAH study to use a primary endpoint assessed by cardiac MRI (cMRI), reported that RV stroke volume (RVSV) increased by 12 mL and pulmonary vascular resistance (PVR) decreased by 38% from baseline (BL) to Week 26 with macitentan.
Purpose
To assess the effect of macitentan on LV function in patients with PAH.
Methods
REPAIR (NCT02310672) was a 52-week, multicentre, open-label, single-arm, phase 4 study assessing the effect of macitentan primarily on RV structure and function, determined by cMRI and right heart catheterisation. Macitentan 10 mg was initiated in treatment-naïve patients, in patients receiving stable background phosphodiesterase type-5 inhibitor (PDE5i) at BL, or in initial combination with PDE5i. Exploratory LV endpoints were assessed by cMRI at Weeks 26 and 52. Safety was assessed up to end of study treatment +30 days in all patients who received ≥1 dose of macitentan (N=87). Patients with BL and Week 26 assessments for both PVR and RVSV were included in the modified Full Analysis Set (mFAS; N=71).
Results
In the mFAS, 57 (80%) patients were female. At BL, median age was 45 years; median (Q1, Q3) six-minute walk distance was 395 (323, 483) m; 48%/51% of patients were WHO functional class II/III; 59% had idiopathic PAH. Compared to BL, at Weeks 26 and 52 there were significant changes in LV cMRI parameters (table). The most common AEs were peripheral oedema (22%), headache (21%) and dizziness (14%).
Conclusions
Macitentan led to improvements in LV mass, volume and function, including clinically-relevant increases in LV stroke volume, at both 26 and 52 weeks in patients with PAH. Safety was consistent with other macitentan clinical trial data.

Abstract
The capacity for subsurface sediments to sequester radionuclide contaminants, such as uranium (U), and retain them after bioremediation efforts are completed is critical to the long-term stewardship of re-mediated sites. In U bioremediation strategies, carbon amendment stimulates bioreduction of U(VI) to U(IV), immobilizing it within the sediments. Sediments enriched in natural organic matter are naturally capable of sequestering significant U, but may serve as sources to the aquifer, contributing to plume persistence. Two types of organic-rich sediments were compared to better understand U release mechanisms. Sediments that were artificially primed for U removal were retrieved from an area previously biostimulated while detrital-rich sediments were collected from a location never subject to amendment. Batch incubations demonstrated that primed sediments rapidly removed uranium from the groundwater, whereas naturally reduced sediments released a sizeable portion of U before U(VI)-reduction commenced. Column experiments confirmed that U release persisted for 65 pore volumes in naturally reduced sediments, demonstrating their sink-source behavior. Acetate addition to primed sediments shifted the microbial community from sulfate-reducing bacteria within Desulfobacteraceae to the iron-reducing Geobacteraceae and Firmicutes, associated with efficient U(VI) removal and retention, respectively. In contrast, Geobacteraceae communities in naturally reduced sediments were replaced by sequences with similarity to Pseudomonas spp. during U release, while U(VI) removal only occurred with enrichment of Firmicutes. These investigations stress the importance of characterizing zones with heterogeneous carbon pools at U-contaminated sites prior to the determination of a remedial strategy to identify areas, which may contribute to long-term sourcing of the contaminants.

Abstract
INTRODUCTION Laparoscopic partial fundoplication for gastro-oesophageal reflux disease (GORD) is reported to have fewer side effects when compared to Nissen fundoplication, but doubts remain over its long term durability in controlling reflux. The aim of this study was to assess outcome of symptoms for all patients presenting with GORD undergoing routine laparoscopic subtotal Lind fundoplication. MATERIALS & METHODS All patients undergoing laparoscopic fundoplication between August, 1999 and November, 2007 performed by a single surgeon were included in the study. The anti-reflux procedure studied was laparoscopic Lind (300°) fundoplication with crural repair in all cases. Patients completed pre and post-operative questionnaires containing validated scoring systems for heartburn, gas bloat, dysphagia and overall patient satisfaction. RESULTS Over the 100-month period, 320 consecutive patients underwent laparoscopic subtotal Lind fundoplication. Of these, 256 (80%) replied to the questionnaire at a mean of 31 months (range 3-96 months) following surgery. 91.4% of respondents had an improvement in heartburn symptom score with a significant reduction in score from 7.74 preoperatively to 1.25 postoperatively (p<0.001). There was also a significant reduction of mean modified Visick score for reflux control (heartburn and regurgitation) from 3.49 preoperatively to 1.48 after surgery (p<0.001). In total, 22 patients developed recurrent reflux symptoms with half of these reporting their recurrence within two years following surgery. Because of this all were tested with post-operative pH testing, yet only one had a 24-h pH time outside the normal range. Overall patient satisfaction was high with a visual analogue score of 9 and 88% of the patients claimed they would have the operation again. CONCLUSION Laparoscopic Lind fundoplication demonstrates excellent reflux control when performed routinely for all patients presenting with GORD. This technique is both durable and efficacious in controlling reflux symptoms.

Abstract
Adolescence is a time of great psychological and physical change. In the UK, girls enter puberty around the age of 10 years with a median age of menarche of 12.9 years; thereafter, it may be several years before regular menstrual cycles are established. Variations in the type and the frequency of periods may create anxiety regarding ill health or serious underlying disorders. With the increase in childhood obesity and subsequent polycystic ovary syndrome, there is a greater awareness and presentation of girls with disorders of menstruation. This review focuses on normal variations of menses and common pathological causes of menstrual problems, including amenorrhoea, dysmenorrhoea and menorrhagia. Further consideration is given to the variations of presentation of polycystic ovary syndrome. It provides a guide to evaluate the various symptoms, investigations and management options.

Abstract
Trench fever became a major worry for the Allied High Command during the First World War because of its debilitating effects on troop performance. The causes of the fever were not previously known, but entomological research identified the body louse (pediculus humanus corporis) as the carrier, and the Royal Army Medical Corps developed effective methods of control through disinfestation. These were markedly influenced by the researches of a young entomologist, Alexander David Peacock, which were conducted under campaign conditions. Peacock subsequently occupied a Chair of Zoology at St. Andrews University for 30 years.

Abstract
Pulmonary hypertension is associated with remodelling of pulmonary vessels. Chronic hypoxia is a common cause of pulmonary hypertension and pulmonary vascular remodelling. Vascular remodelling is characterised largely by fibroblast, smooth muscle and endothelial cell proliferation, which results in lumen obliteration. Chronic hypoxia elicits expression of mitogens, growth factors and cytokines by fibroblasts and endothelial cells, and also the suppression of endothelial nitric oxide synthase. Although hypoxic pulmonary vascular remodelling is associated with medial hypertrophy, many in vitro studies have found that hypoxia does not lead to a direct increase in smooth muscle cell proliferation. This paradox is not well understood and this review aims to examine the various reasons why this might be so. The present authors reviewed data from in vitro studies and also considered whether hypoxia could act on adjacent cells such as fibroblasts and endothelial cells to trigger smooth muscle cell proliferation. It is possible that hypoxia is sensed by fibroblasts, endothelial cells, or both, and relayed to adjacent pulmonary artery smooth muscle cells by intercellular signalling, causing proliferation. The present article reviews the data from in vitro studies of hypoxia on the three cellular components of the pulmonary vascular wall, namely endothelial cells, smooth muscle cells and fibroblasts.

Abstract
17020 Background: Indigent, minority women with breast cancer present with later stage disease, often because of lack of access to affordable screening tests. Breast exam and mammography are effective at early detection. A screening program targeting minority women is important, especially in an area with a high poverty rate. The most effective way to reach this population, though, has not been well established. Methods: From 11/03–7/05, 4 breast cancer screenings were performed at our cancer center which targeted poor, minority populations in the Cleveland area. Despite culturally appropriate advertisements and free exams by physicians, only 42 women were screened. To improve upon this, a bilingual community breast liaison was hired. An advisory council of community representatives was established which led to collaborations with over 100 neighborhood agencies. The venue for the screenings was changed to easily accessible locations (churches, shelters) and transportation was provided. Free clinical breast exams (CBE) were performed by experienced physicians and on-site mammograms (mam) were done. From 10/05–10/06, 7 community breast screenings were held. 403 women were screened and over 2000 were educated. Results: 98% were impoverished; 94% had an annual income of <$25,000. 78% had no health insurance. Median age=46 (range 35–89). 31% Latino; 46% AA; 16% Caucasian. Many pts had not had a mam (91%) or CBE (84%) within the past year; many never had either screening test before (31% never had a mam and 17% never had a CBE). The most common reason for this was lack of insurance (60%). “Too young” was the second most common reason (7%). Most common reason for coming to screenings: free services (49%). Of 403 pts screened, 27/371 had abnormalities on CBE and 26/293 mam were abnormal. Thus far, 2 cases of breast cancer have been diagnosed (stages I and II). Conclusion: Indigent minority women do not receive adequate breast cancer screening due to many barriers, including cost. To reduce this disparity, our center targeted this population. After adjusting our approach, screening attendance markedly improved, increasing from 42 to 403 pts screened. This improvement was due to cancer center services being brought out to the community and an active engagement of community organizations. No significant financial relationships to disclose.
