Abstract
Feline aelurostrongylosis, caused by the metastrongyloid nematode Aelurostrongylus abstrusus, is an important gastropod-borne parasitic lung disease in cats. Infection with A. abstrusus is widespread globally, but the increasing awareness of this parasite and the advent of more sensitive diagnostics have contributed to the apparent increase in its prevalence and geographic expansion. Clinical features may range in severity from subclinical to life-threatening respiratory disease. Parasitological standard techniques, such as visualization of the nematode first larval stage in faecal and respiratory (bronchial mucus or pleural fluid) samples, remain the mainstays of diagnosis. However, diagnosis is evolving with recent advances in serological and molecular testing, which can improve the time to initiation of effective anthelmintic therapy. Despite numerous anthelmintics that are now available as treatment options, the role of host immunity and lifestyle factors in selecting cats that may benefit from more targeted anthelmintic prophylaxis or treatment practice remains unclear and is likely to guide therapeutic choices as newer data become available. This review summarizes the biology, epidemiology, pathophysiology, diagnosis and treatment options currently available for feline aelurostrongylosis.

Abstract
Objective To describe the outcomes of a public hospital maternity unit in rural New South Wales (NSW) following the adaptation of the service from an obstetrician and general practitioner‐obstetrician (GPO)‐led birthing service to a low‐risk midwifery group practice (MGP) model of care with a planned caesarean section service (PCS). Design A retrospective descriptive study using quantitative methodology. Setting Maternity unit in a small public hospital in rural New South Wales, Australia. Participants Data were extracted from the ward‐based birth register for 1172 births at the service between July 2007 and June 2012. Main outcome measures Birth numbers, maternal characteristics, labour, birthing and neonatal outcomes. Results There were 750 births over 29 months in GPO and 277 and 145 births over 31 months in MGP and PCS, respectively, totalling 422 births following the change in model of care. The GPO had 553 (73.7%) vaginal births and 197 (26.3%) caesarean section (CS) births (139 planned and 58 unplanned). There were almost universal normal vaginal births in MGP (>99% or 276). For normal vaginal births, more women in MGP had no analgesia (45.3% versus 25.1%) or non‐invasive analgesia (47.9% versus 38.6%) and episiotomy was less common in MGP than GPO (1.9% versus 3.4%). Neonatal outcomes were similar for both groups with no difference between Apgar scores at 5 min, neonatal resuscitations or transfer to high‐level special care nurseries. Conclusion This study demonstrates how a rural maternity service maintained quality care outcomes for low‐risk women following the adaptation from a GPO to an MGP service.

Abstract
The use of intra-detrusor onabotulinumtoxinA (Botox®) in patients with myasthenia gravis has not been reported, and little evidence exists to substantiate a complete contraindication of Botox use in this population. Here, we present two cases of comorbid overactive bladder (OAB) and myasthenia gravis successfully treated with intra-detrusor Botox.

Abstract
BACKGROUND The safest ranges of oxygen saturation in preterm infants have been the subject of debate. METHODS In two trials, conducted in Australia and the United Kingdom, infants born before 28 weeks' gestation were randomly assigned to either a lower (85 to 89%) or a higher (91 to 95%) oxygen-saturation range. During enrollment, the oximeters were revised to correct a calibration-algorithm artifact. The primary outcome was death or disability at a corrected gestational age of 2 years; this outcome was evaluated among infants whose oxygen saturation was measured with any study oximeter in the Australian trial and those whose oxygen saturation was measured with a revised oximeter in the U.K. trial. RESULTS After 1135 infants in Australia and 973 infants in the United Kingdom had been enrolled in the trial, an interim analysis showed increased mortality at a corrected gestational age of 36 weeks, and enrollment was stopped. Death or disability in the Australian trial (with all oximeters included) occurred in 247 of 549 infants (45.0%) in the lower-target group versus 217 of 545 infants (39.8%) in the higher-target group (adjusted relative risk, 1.12; 95% confidence interval [CI], 0.98 to 1.27; P=0.10); death or disability in the U.K. trial (with only revised oximeters included) occurred in 185 of 366 infants (50.5%) in the lower-target group versus 164 of 357 infants (45.9%) in the higher-target group (adjusted relative risk, 1.10; 95% CI, 0.97 to 1.24; P=0.15). In post hoc combined, unadjusted analyses that included all oximeters, death or disability occurred in 492 of 1022 infants (48.1%) in the lower-target group versus 437 of 1013 infants (43.1%) in the higher-target group (relative risk, 1.11; 95% CI, 1.01 to 1.23; P=0.02), and death occurred in 222 of 1045 infants (21.2%) in the lower-target group versus 185 of 1045 infants (17.7%) in the higher-target group (relative risk, 1.20; 95% CI, 1.01 to 1.43; P=0.04). In the group in which revised oximeters were used, death or disability occurred in 287 of 580 infants (49.5%) in the lower-target group versus 248 of 563 infants (44.0%) in the higher-target group (relative risk, 1.12; 95% CI, 0.99 to 1.27; P=0.07), and death occurred in 144 of 587 infants (24.5%) versus 99 of 586 infants (16.9%) (relative risk, 1.45; 95% CI, 1.16 to 1.82; P=0.001). CONCLUSIONS Use of an oxygen-saturation target range of 85 to 89% versus 91 to 95% resulted in nonsignificantly higher rates of death or disability at 2 years in each trial but in significantly increased risks of this combined outcome and of death alone in post hoc combined analyses.

Abstract
Buxtonellosis is a disease caused by the ciliated protozoan Buxtonella sulcata (Jameson, 1926). B. sulcata is a common protozoan of ruminants and may result in subclinical infection or clinical disease including diarrhea. This study examined the prevalence of B. sulcata in cattle from Sanadaj province, Iran. Faecal samples were collected from cattle in the province from May 2013 to June 2014. A total of 217 cattle were selected randomly according to the age, sex, health, management system and season. In total, 99 cattle (45.63%) were found to be infected with B. sulcata. In adults, prevalence of B. sulcata infection (51.64%) was higher than calves (28.58%) and young cattle (40.55%). The prevalence of B. sulcata infection was also found to be higher in female (47.32%) than male (38.46) cattle. B. sulcata infection was significantly (p<0.05) higher in poor health cattle (body condition and weight) (79.54%) than healthy cattle (24.47%). This study demonstrates that cattle are highly susceptible to B. sulcata infection under a variety of housing and environmental conditions in this region of Iran. The study also demonstrates a significant effect of infection on cattle health.

Transurethral Resection of the Prostate Biopsy of Suspected Anterior Prostate Cancers Identified by Multiparametric Magnetic Resonance Imaging: A Pilot Study of a Novel Technique.

Abstract
OBJECTIVE To describe a novel biopsy technique that involves performing a cognitively directed transurethral resection of the prostate (TURP) to diagnose suspected anterior prostate cancers (APCs) detected by multiparametric magnetic resonance imaging (mpMRI) in patients with prior negative transrectal ultrasound (TRUS)-guided biopsies. METHODS This is a prospective study in which participants aged 50-75 were offered inclusion if they had an elevated prostate-specific antigen level, a lesion suspicious for APC on mpMRI, and at least one prior negative TRUS-guided prostate biopsy. Prostatic mpMRI was acquired with a 3-Tesla machine without endorectal coil. Preoperative review of the mpMRI images was used to target the suspected APC on TURP biopsy. The primary outcome was the detection rate of clinically significant prostate cancer, defined as the presence of any Gleason pattern ≥ 4 in the specimen. Secondary outcomes included biopsy-related complications including 30-day readmissions. RESULTS A total of 16 consecutive participants were enrolled. Median age was 64 years, median prostate-specific antigen was 12.4 ng/mL, and participants had a median of 2 prior negative TRUS-guided biopsies. Thirteen (81.3%) participants had clinically significant APCs detected by TURP biopsy. One participant was readmitted within 30-days postprocedure for continuous bladder irrigation. Seven participants (43.8%) underwent radical prostatectomy that confirmed clinically significant disease in all 7 participants. CONCLUSION Among participants with anterior prostate lesions on mpMRI and prior negative TRUS-guided biopsy, TURP biopsy does detect some clinically significant cancers. This study serves as a proof of concept and further comparative trials are needed prior to widespread adoption.

Abstract
OBJECTIVES The purpose of this study was to investigate whether heart failure patients with narrow QRS duration (or right bundle branch block) but with long PR interval gain acute hemodynamic benefit from atrioventricular (AV) optimization. We tested this with biventricular pacing and (to deliver pure AV shortening) direct His bundle pacing. BACKGROUND Benefits of pacing for heart failure have previously been indicated by acute hemodynamic studies and verified in outcome studies. A new target for pacing in heart failure may be PR interval prolongation, which is associated with 58% higher mortality regardless of QRS duration. METHODS We enrolled 16 consecutive patients with systolic heart failure, PR interval prolongation (mean, 254 ± 62 ms) and narrow QRS duration (n = 13; mean QRS duration: 119 ± 17 ms) or right bundle branch block (n = 3; mean, QRS duration: 156 ± 18 ms). We successfully delivered temporary direct His bundle pacing in 14 patients and temporary biventricular pacing in 14 participants. We performed AV optimization using invasive systolic blood pressure obtaining parabolic responses (mean R2: 0.90 for His, and 0.85 for biventricular pacing). RESULTS The mean increment in systolic BP compared with intrinsic ventricular conduction was 4.1 mm Hg (95% confidence interval [CI]: +1.9 to +6.2 mm Hg for His and 4.3 mm Hg [95% CI: +2.0 to +6.5 mm Hg] for biventricular pacing. QRS duration lengthened with biventricular pacing (change = +22 ms [95% CI: +18 to +25 ms]) but not with His pacing (change = +0.5 ms [95% CI: -2.6 to +3.6 ms). CONCLUSIONS AV-optimized pacing improves acute hemodynamic function in patients with heart failure and long PR interval without left bundle branch block. That it can be achieved by single-site His pacing shows that its mechanism is AV shortening. The improvement is ∼60% of the effect size previously reported for biventricular pacing in left bundle branch block. Randomized, blinded trials are warranted to test for long-term beneficial effects.

Abstract
Carbon nanotubes have been observed to emit ultraviolet, visible and infrared radiation when exposed to microwaves. We have performed experiments in which both short (0.5 μm–2 μm) and long (5 μm–30 μm) single and double-walled carbon nanotubes were exposed to 2.46 GHz microwaves at a pressure of ~ 10-6 Torr. Structural modifications of the carbon nanotubes due to microwave absorption have been studied using the Raman spectroscopy G-band and D-band intensities, which suggest that microwave irradiation at relatively low pressure results in an increase in nanotube defects, especially in the case of the long nanotubes. Furthermore, a comparison of the spectra of the radiation emitted from the nanotubes suggests that the longer nanotubes emitted radiation of much greater intensity than the shorter nanotubes. Based on the results of the experiments and results described in previous reports, the ultraviolet, visible and infrared radiation emitted as the result of microwave absorption by carbon nanotubes seems to be primarily blackbody radiation emitted due to Joule heating. However, the presence of several broad photopeaks in the spectra of the emitted radiation (which do not seem to be related to gases absorbed by the nanotubes or the presence of catalyst particles) suggest that emissions are not the result of Joule heating alone.

Abstract
The aim of this review is to provide a comprehensive update on the biology, epidemiology, clinical features, diagnosis, treatment, and prevention of canine cardio-pulmonary angiostrongylosis. This cardiopulmonary disease is caused by infection by the metastrongyloid nematode Angiostrongylus vasorum. The parasite has an indirect life cycle that involves at least two different hosts, gastropod molluscs (intermediate host) and canids (definitive host). A. vasorum represents a common and serious problem for dogs in areas of endemicity, and because of the expansion of its geographical boundaries to many areas where it was absent or uncommon; its global burden is escalating. A. vasorum infection in dogs can result in serious disorders with potentially fatal consequences. Diagnosis in the live patient depends on faecal analysis, PCR or blood testing for parasite antigens or anti-parasite antibodies. Identification of parasites in fluids and tissues is rarely possible except post mortem, while diagnostic imaging and clinical examinations do not lead to a definitive diagnosis. Treatment normally requires the administration of anthelmintic drugs, and sometimes supportive therapy for complications resulting from infection.

Abstract
BACKGROUND Early respiratory management of very low birth weight infants has changed over recent years to a practice of early use of CPAP with early selective surfactant administration, and decreased use of mechanical ventilation. One strategy is to use the combination of surfactant and prompt extubation to nasal continuous positive airway pressure (INtubate, SURfactant, Extubate, or INSURE). The aim of this study is to describe blood flow and ductal flow in a prospective cohort during the transitional period when this respiratory management strategy is used. METHODS Inborn infants <29week gestation underwent INSURE within 30min of birth using 200mg/kg Curosurf. Blood pressure and blood flow parameters (RVO, LVO, SVC flow, ductus arteriosus) were measured at 6, 24 and 72h of age and information on morbidity was collected. RESULTS Sixty-eight infants with a median (range) weight of 940 (450-1380) g were studied. 13 (19%) patients needed mechanical ventilation within 72h of life (INSURE failure). Blood flows and blood pressure were within reported ranges. Eleven (16%) patients had a blood pressure <gestational age and 9 (13%) patients had low blood flow. CONCLUSION These data show a low prevalence of low blood pressure and low blood flow in the first 3days after INSURE as compared to cohorts where mechanical ventilation was preferred during transition. We speculate that altered ventilation strategies have helped decrease the incidence of low blood flow and low blood pressure.

Abstract
230 Background: Prostatic MRI allows for identification of cancerous lesions in patients with a prior negative TRUS biopsy. Although in-gantry and MR-ultrasound fusion technologies have been reported, access to these technologies is limited. Here we present a novel technique to sample anterior lesions suspicious for prostate cancer (PCa) identified by MRI with transurethral (TURP) biopsy. Methods: MRI studies ordered by a single uro-oncologist at a tertiary center from 2007 to 2013 were reviewed. Patients were included if their studies met the following criteria: prostate MRI (n=148), indication for MRI was prior negative TRUS biopsy (n=48), PCa considered likely by reading radiologist (n=25) and anterior tumor location (n=7). Anterior tumors were those 17mm or more from the posterior prostate margin. Medical records were thoroughly reviewed. Additionally, regional medical databases were searched for 30 day readmission, emergency room (ER) visit, or positive bacterial culture result. Biopsy patients were treated with the standard monopolar TURP clinical pathway at our center. TURP sampling was directed by pre-procedural review of MRI images and report by the surgeon. MRI imaging was read by a single radiologist and obtained with a 3-T MRI with no endorectal coil employing T1, T2, DWI, and DCE sequences. Results: All seven patients identified with anterior tumors received TURP biopsy. Patients had a mean age of 63.6, Prostate-specific antigen of 13.3 ng/mL and a mean of 2.3 prior negative TRUS biopsies. There were no immediate complications reported. In 30 day follow-up data, no patients had a postoperative infection, although one patient was assessed in the ER for self-resolving hematuria and one patient was admitted for hematuria. Mean specimen weight was 4g and all but one patient had Gleason 7 or higher PCa on biopsy. This study demonstrated that MRI followed by TURP biopsy for anterior PCa had an 85.7% cancer detection rate for clinically significant anterior cancers. Conclusions: This pilot study demonstrates that cognitively directed TURP biopsy for MRI-identified anterior prostate lesions is feasible, has an excellent pickup rate for clinically significant cancer, and does not require access to limited technology.
