Abstract
Abstract
Introduction
Intra-operative predictors of mid-to-late mitral valve dysfunction after surgical repair of mitral regurgitation (MR) caused by prolapse remain poorly characterized. This study aims to evaluate the effect of annuloplasty prosthesis size on post-operative MV hemodynamics at rest and during exercise, and to identify perioperative predictors of MV dysfunction.
Methods
104 patients were randomly assigned to resection and preservation for surgical treatment of posterior leaflet prolapse in the Canadian Mitral Research Alliance CardioLink-2 study. Echocardiograms were performed at baseline and 1 year postoperatively. Intraoperative TEE was performed to assess immediate MV gradients. Exercise TTE was performed 1 year after repair. Linear regression analysis was used to identify associations between MV indices (rest and peak exercise gradients) at 12 months, and perioperative echocardiographic and clinical factors.
Results
Mean age of participants was 65±10 years, and 83% were male. Larger annuloplasty size was associated with lower transmitral gradients at rest and during peak exercise. In multivariable analysis, annuloplasty size ≥34mm was associated with lower mean and peak rest and exercise gradients at 12 months, after adjustment for repair type, age, sex, and BSA (p<0.001). Higher pre-operative pulmonary artery pressures were associated with reduced functional capacity post-operatively. Intra-operative TEE gradients predict resting and exercise MV hemodynamics at 1 year.
Conclusion
Annuloplasty size ≥34mm is associated with improved MV hemodynamics at rest and during peak exercise 1 year post MV repair. MV repair prior to onset of pulmonary hypertension confers favourable post operative functional capacity. Finally, intra-operative TEE can be used to identify patients at risk of mitral valve dysfunction within 1 year of repair.

Abstract
Abstract
Background
The EMPA-HEART trial showed a reduction in left ventricular (LV) mass index by cardiac MRI at 6 months in patients treated with Empagliflozin vs placebo. A secondary analysis of key echocardiographic parameters was performed to provide further insight into the mechanism of LV remodeling.
Methods
All patients enrolled prospectively underwent transthoracic echocardiography (TTE) at baseline and at 6 months. Measurements were performed according to the American Society of Echocardiography guidelines. Key outcomes of interest included changes in diastolic function and right ventricle parameters at 6 months in patients treated with Empagliflozin vs placebo.
Results
A total of 97 patients were enrolled (49 treated with Empagliflozin and 48 in the placebo group). There was no significant difference in the change in average E/E' at 6-months in the Empagliflozin group vs placebo (−0.4 vs +0.2, adjusted difference −0.2, 95% CI [−1.3 to 0.82], p=0.7) Similarly, there was no difference between the groups in secondary TTE parameters (Table 1). Subgroup analyses showed no benefit among patients with baseline LVEF >50% vs. ≤50%, and baseline LV mass index ≥60 g/m2 vs <60 g/m2.

Abstract
Abstract
Background
Glucose lowering drugs or strategies (GLDS) have varied effects on major adverse cardiovascular events (MACE) and heart failure (HF) in cardiovascular outcomes trials. Mechanisms driving cardiovascular risk reduction remain elusive.
Methods
We searched MEDLINE, PubMed, and meeting abstracts up to 11/21/2018 for large GLDS cardiovascular outcome trials (CVOTs) in patients with or at risk for type 2 diabetes. Primary endpoints of MACE and HF were evaluated with random effects risk ratios (RR) and explored by baseline CVD subgroups and meta-regression by weight change across treatment arms.
Results
In 27 GLDS CVOTs, a total 207,820 patients, median age 63 years, 64% male, 64% CVD and 11% with prior HF were studied over a mean 3.8 years with 20,118 (10%) patients having MACE and 7,212 (4%) a HF event. Compared with standard care, GLDS overall lowered MACE (RR 0.92, P<0.ehz745.01171) but not HF (RR 1.01, P=0.91). Across GLDS, the magnitude and directionality varied modestly for MACE RR (P-int=0.07) but markedly for HF (P-int<0.ehz745.01171). Meta-regression showed a change in HF RR by 6% (95% CI 3%-9%) per 1 kg weight gain/loss between treatment arms (P=0.0006; Figure). In 9 trials of GLDS that achieved marked weight loss (lifestyle, GLP1 agonists, SGLT2 inhibitors), MACE benefit was confined to patients with baseline CVD (RR 0.89 [0.84–0.95] versus without (RR 1.02 [0.91–1.15]; P-int=0.01) with consistent HF effect (RR 0.80 [0.72–0.88] vs RR 0.76 [0.56–1.03]; P-int=0.74).
Heart Failure Risk and Changes in Weight
Conclusion
HF outcomes were improved with GLDS that lower weight. Among diabetes GLDS that lower weight, there was a robust risk reduction in atherothrombotic and heart failure events, with the MACE benefit confined to patients with established CVD.

Abstract
Ethnic differences in both disease susceptibility and expression have been noted in systemic lupus erythematosus (SLE). This review focuses on the evidence of disparities between SLE patients of Asian and Caucasian descent, the two predominant ethnic groups affected by SLE in the Australian context. While epidemiological studies suggest higher rates of SLE among Asian patients, multi-ethnic cohort studies have allowed direct comparison of disease characteristics between different ethnic groups. Such studies suggest that Asians are affected by more severe SLE across several disease parameters, including increased renal involvement, autoantibody positivity, disease activity and damage accumulation. As delineation of these disparities becomes clearer, uncovering the biological basis of such differences poses a significant opportunity to progress understanding of SLE pathogenesis. Understanding ethnic variation in disease provides a platform for an individualised approach to risk assessment, monitoring and management of SLE.

Abstract
OBJECTIVE Systemic lupus erythematosus (SLE), an autoimmune condition with diverse clinical manifestations, is reported to have different expression in populations of different ancestry. Most previous studies compared patients of different ethnic groups from geographically distinct cohorts. In our study, we aimed to characterize disease manifestations in patients of different ethnic groups from a single centre, and studied patterns of disease activity over time. METHODS Demographics, baseline disease characteristics and autoantibody profiles, and disease activity (SLEDAI) measured at each visit, were captured from all consenting patients prospectively followed between 2007 and 2011 in an urban teaching hospital lupus clinic. Ethnicity was self-reported. RESULTS Asian ethnicity was significantly associated with more clinically severe SLE. Time-adjusted mean SLEDAI (p = 0.01) and maximum SLEDAI (p = 0.0018) were significantly higher in Asian patients. Asians were more likely to have renal disease (OR 2.9, 95% CI 1.4-5.98; p = 0.004) and persistently active disease (PAD) (OR 2.14, 95% CI 1.05-4.38, p = 0.04). Asian lupus patients also had a significantly higher proportion of autoantibody positivity to anti-dsDNA, anti-RNP, anti-Sm, anti-Ro and anti-La, as well as increased likelihood of hypocomplementaemia and immunosuppressant use. CONCLUSION In this single-cohort study, Asian ethnicity was found to be associated with increased SLE disease activity. This suggests significant inter-ethnic genetic contributions to the regulation of autoimmune responses and disease severity in SLE.

Abstract
Release of excitatory amino acids and dopamine plays a central role in neuronal damage after cerebral ischaemia. In the present study, we used an in vitro model of ischaemia to investigate the effects of sevoflurane on dopamine, glutamate and aspartate efflux from rat corticostriatal slices. Slices were superfused with artificial cerebrospinal fluid at 34 degrees C and episodes of 'ischaemia' were mimicked by removal of oxygen and reduction in glucose concentration from 4 to 2 mmol litre(-1) for < or = 30 min. Dopamine efflux was monitored in situ by voltammetry while glutamate and aspartate concentrations in samples of the superfusate were measured by HPLC with fluorescence detection. Neurotransmitter outflow from slices was measured in the absence or presence of sevoflurane (4%). After induction of ischaemia in control slices, there was a mean (SEM) delay of 166 (7) s (n = 5) before sudden efflux of dopamine which reached a maximum extracellular concentration of 77.0 (15.2) micromol litre(-1). Sevoflurane (4%) reduced the rate of dopamine efflux during ischaemia (6.90 (1.5) and 4.73 (1.76) micromol litre(-1) s(-1) in controls and sevoflurane-treated slices, respectively; P<0.05), without affecting its onset or magnitude. Excitatory amino acid efflux was much slower. lschaemia-induced glutamate efflux had not reached maximum after 30 min of ischaemia. Basal (pre-ischaemic) glutamate and aspartate efflux per slice was 94.8 (24.8) and 69.3 (31.5) nmol litre(-1) superfusate (n = 4) and was not significantly reduced by 4% sevoflurane. lschaemia greatly increased glutamate and aspartate efflux (to a maximum of 919 (244)% and 974 (489)% of control, respectively). However, ischaemia-induced efflux of both glutamate and aspartate was significantly reduced by 4% sevoflurane (P < 0.001 for glutamate, P < 0.01 for aspartate). In summary, sevoflurane may owe part of its reported neuroprotective effect to a reduction of ischaemia-induced efflux of excitatory amino acids and, to a lesser extent, dopamine.

Abstract
We reviewed adverse event (AE) data in the National Cooperative Growth Study from start-up (1985) until January 1, 1999. Enrollment was 33,161. A total of 2,632 AE reports were received; 863 were serious events, with 156 deaths. The most common cause of death was recurrence of intracranial neoplasm. There were 20 reports of leukemia, and the standard morbidity ratio (SMR) was 0.73 (95% CI: 0.20-1.86) for the four cases without risk factors. There were 35 reports of extracranial nonleukemic malignancy, and the SMR was 0.44 (95% CI: 0.24-0.74) for the 14 cases without risk factors. The recurrence rate for all brain tumors present at baseline was 7.6%, and for craniopharyngiomas, 6.4%. There were 49 reports of intracranial hypertension (20 patients had papilledema), 68 reports of diabetes/hyperglycemia, 45 of slipped capital femoral epiphysis, 136 of scoliosis, and five of pancreatitis. There was no evidence of increased incidence of leukemia or extracranial nonleukemic malignancies among patients without prior risk factors. Intracranial hypertension does not necessarily occur early in growth hormone therapy. Other findings were consistent with past observations.

Abstract
Two murine monoclonal antibodies, IIG5 (IgG3) and IVE8 (IgG2a), that bind to Pseudomonas aeruginosa type a flagella and type b flagella, respectively, were prepared by conventional hybridoma methodology. Specificity of each monoclonal antibody for type a or type b flagella was demonstrated by enzyme-linked immunosorbent assay, indirect immunofluorescence, and immunoblotting. The percentage of P. aeruginosa isolates recognized by each monoclonal antibody was analyzed by enzyme-linked immunosorbent assay. Among a panel of 257 flagellated P. aeruginosa clinical isolates, IIG5 bound to 67.7% of the isolates and IVE8 bound to another 30.7%, for a combined coverage of 98.4%. Inhibition of motility of P. aeruginosa by the monoclonal antibodies was observed in vitro in a soft agar assay and was dose dependent. The protective efficacy of IIG5 and IVE8 was examined in a mouse burn wound sepsis model. The antiflagellum monoclonal antibodies provided specific and significant prophylactic and therapeutic protection against lethal challenge with P. aeruginosa strains.

Abstract
Rest homes have become a major component of the health care system for frail elderly persons and deinstitutionalized psychiatric patients. Although psychoactive medications are frequently used in rest homes, there is little detailed information about the extent of such use, its supervision, or its effects. In a survey of a random sample of 55 rest homes in Massachusetts, we found that 55 percent of the residents were taking at least one psychoactive medication. Antipsychotic medications were being administered to 39 percent; of these, 18 percent were receiving two or more such drugs. In a follow-up investigation, we studied 837 residents in 44 rest homes with particularly high levels of antipsychotic-drug use. About half the residents had no evidence of participation by a physician in decisions about their mental health during the year of the study. A third of the residents had performance deficits on mental-status testing that indicated serious cognitive impairment, although the causal relation of such impairment to medication use could not be determined. Six percent had evidence of moderate or severe tardive dyskinesia, probably as a side effect of medication. An assessment of staff competence revealed a low level of comprehension of the purpose and side effects of commonly used psychoactive drugs. We conclude that psychoactive drugs are widely used in rest homes, with little medical supervision or understanding by staff members of their possible side effects.

Abstract
Several biochemical effects of 5-fluorouracil (5-FU) including inhibition of the incorporation of 3H-deoxyuridine (3H-UdR) into DNA, inhibition of ribosome formation, and formation of 5-fluoro-2'-deoxyuridine-5'-monophosphate (FdUMP) were examined in samples of human colon carcinomas to determine if any of these drug effects might have predictive value as a reliable guide to 5-FU therapy. For comparison, the solid rat Walker 256 carcinosarcoma, which is only minimally responsive to 5-FU, was also studied. For each of the biochemical effects of 5-FU measured in the various samples of Walker 256 tumors, the responses were consistent and varied within a narrow range. In contrast, the formation of FdUMP from 5-FU and the degree of inhibition of the incorporation of 3H-UdR into DNA by 5-FU were extremely variable in the population of human colon carcinomas examined. In all human tumors examined, 5-FU caused a reduction in the formation of ribosomes, but even in the absence of 5-FU, the total amount of ribosome synthesis was so low that it makes measurement difficult to quantitate. Based on our data, a study might be warranted to determine if there is a correlation between FdUMP formation and responsiveness of colon carcinoma to 5-FU therapy.
