Abstract
Lumbar epidurals are frequently inserted for women in labour as they provide excellent analgesia. One of the more common procedural complications is post-dural puncture headache which can be associated with auditory symptoms such as hearing loss and tinnitus and can be treated with an epidural blood patch. Sphenopalatine ganglion blocks have also been used to treat post-dural puncture headache but have not been previously shown to resolve the associated tinnitus. We report a case where postural neck pain and tinnitus from an accidental dural puncture during lumbar epidural insertion for labour analgesia was treated successfully with a sphenopalatine ganglion block. Further, we explore the literature on the cause of tinnitus in post-dural puncture headache and the possible mechanism by which a sphenopalatine ganglion block relieves both post-dural puncture headache and the associated tinnitus.

Abstract
OBJECTIVE To assess whether in adults with dyslipidemia, statins reduce cardiovascular events, mortality, and adverse effects when compared to fibrates. METHODS Systematic review and meta-analysis of head-to-head randomized trials of statin and fibrate monotherapy. MEDLINE, EMBASE, Cochrane, WHO International Controlled Trials Registry Platform, and ClinicalTrials.gov were searched through October 30, 2019. Trials that had a follow-up of at least 28 days, and reported mortality or a cardiovascular outcome of interest were eligible for inclusion. Efficacy outcomes were cardiovascular mortality and major cardiovascular events. Safety outcomes included myalgia, serious adverse effects, elevated serum creatinine, and elevated serum alanine aminotransferase. Odds ratios (OR) and 95% confidence intervals (CI) were estimated using the Mantel-Haenszel fixed-effect model, and heterogeneity was assessed using the I2 statistic. RESULTS We included 19 eligible trials that directly compared statin and fibrate monotherapy and reported mortality or a cardiovascular event. Studies had a limited duration of follow-up (range 10 weeks to 2 years). We did not find any evidence of a difference between statins and fibrates for cardiovascular mortality (OR 2.35, 95% CI 0.94-5.86, I2 = 0%; ten studies, n = 2657; low certainty), major cardiovascular events (OR 1.15, 95% CI 0.80-1.65, I2 = 13%; 19 studies, n = 7619; low certainty), and myalgia (OR 1.32, 95% CI 0.95-1.83, I2 = 0%; ten studies, n = 6090; low certainty). Statins had less serious adverse effects (OR 0.57, 95% CI 0.36-0.91, I2 = 0%; nine studies, n = 3749; moderate certainty), less elevations in serum creatinine (OR 0.17, 95% CI 0.08-0.36, I2 = 0%; six studies, n = 2553; high certainty), and more elevations in alanine aminotransferase (OR 1.43, 95% CI 1.03-1.99, I2 = 44%; seven studies, n = 5225; low certainty). CONCLUSIONS The eligible randomized trials of statins versus fibrates were designed to assess short-term lipid outcomes, making it difficult to have certainty about the direct comparative effect on cardiovascular outcomes and mortality. With the exception of myalgia, use of a statin appeared to have a lower incidence of adverse effects compared to use of a fibrate.

Abstract
Balloon aortic valvuloplasty (BAV) intervention is used as destination therapy or as a bridge to percutaneous or surgical aortic valve intervention. BAV is traditionally performed via a transfemoral approach; however, this may not be feasible in all patients due to peripheral vascular disease. We present a case of BAV performed via bilateral transradial access utilizing simultaneous deployment of two angioplasty balloons.

Prognostic Value of Fat Mass and Skeletal Muscle Mass Determined by Computed Tomography in Patients Who Underwent Transcatheter Aortic Valve Implantation. Am J Cardiol 2016; 117:828-33.

Abstract
Body composition (fat mass [FM] and skeletal muscle mass [SMM]) predicts clinical outcomes. In particular, loss of SMM (sarcopenia) is associated with frailty and mortality. There are no data on the prevalence and impact of FM and SMM in patients undergoing transcatheter aortic valve implantation (TAVI). The objective of this study is to determine body composition from pre-TAVI computed tomography (CT) and evaluate its association with clinical outcomes in patients who underwent TAVI. A total of 460 patients (mean age 81 ± 8 years, men: 51%) were included. Pre-TAVI CTs of the aorto-ilio-femoral axis were analyzed for FM and SMM cross-sectional area at the level of the third lumbar vertebrae (L3). Regression equations correlating cross-sectional area at L3 to total body FM and SMM were used to determine prevalence of sarcopenia, obesity, and sarcopenic obesity in patients (64%, 65%, and 46%, respectively). Most TAVI procedures were performed through a transfemoral approach (59%) using a balloon-expandable valve (94%). The 30-day and mid-term (median 12 months [interquartile range 6 to 27]) mortality rates were 6.1% and 29.6%, respectively. FM had no association with clinical outcomes, but sarcopenia predicted cumulative mortality (hazard ratio 1.55, 95% confidence interval 1.02 to 2.36, p = 0.04). In conclusion, body composition analysis from pre-TAVI CT is feasible. Sarcopenia, obesity, and sarcopenic obesity are prevalent in the TAVI population, with sarcopenia predictive of cumulative mortality.

Chronic obstructive pulmonary disease in patients undergoing transcatheter aortic valve implantation: insights on clinical outcomes, prognostic markers, and functional status changes. JACC Cardiovasc Interv 2014; 6:1072-84. [PMID: 24156967 DOI: 10.1016/j.jcin.2013.06.008] [Citation(s) in RCA: 81] [Impact Index Per Article: 8.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/15/2013] [Revised: 06/18/2013] [Accepted: 06/20/2013] [Indexed: 11/15/2022]
Abstract
OBJECTIVES This study sought to determine the effects of chronic obstructive pulmonary disease (COPD) on clinical outcomes in patients undergoing transcatheter aortic valve implantation (TAVI) and to determine the factors associated with worse outcomes in COPD patients. BACKGROUND No data exist on the factors determining poorer outcomes in COPD patients undergoing TAVI. METHODS A total of 319 consecutive patients (29.5% with COPD) who underwent TAVI were studied. Functional status was evaluated by New York Heart Association (NYHA) functional class, Duke Activity Status Index, and the 6-min walk test (6MWT) at baseline and at 6 to 12 months. The TAVI treatment was considered futile if the patient either died or did not improve in NYHA functional class at 6-month follow-up. RESULTS Survival rates at 1 year were 70.6% in COPD patients and 84.5% in patients without COPD (p = 0.008). COPD was an independent predictor of cumulative mortality after TAVI (hazard ratio: 1.84; 95% confidence interval: 1.08 to 3.13; p = 0.026). Improvement in functional status was observed after TAVI (p < 0.001 for NYHA functional class, Duke Activity Status Index, and 6MWT), but COPD patients exhibited less (p = 0.036) improvement in NYHA functional class. Among COPD patients, a shorter 6MWT distance predicted cumulative mortality (p = 0.013), whereas poorer baseline spirometry results (FEV1 [forced expiratory volume in the first second of expiration]) determined a higher rate of periprocedural pulmonary complications (p = 0.040). The TAVI treatment was futile in 40 COPD patients (42.5%) and a baseline 6MWT distance <170 m best determined the lack of benefit after TAVI (p = 0.002). CONCLUSIONS COPD was associated with a higher rate of mortality at mid-term follow-up. Among COPD patients, a higher degree of airway obstruction and a lower exercise capacity determined a higher risk of pulmonary complications and mortality, respectively. TAVI was futile in more than one-third of the COPD patients, and a shorter distance walked at the 6MWT predicted the lack of benefit after TAVI. These results may help to improve the clinical decision-making process in this challenging group of patients.

Abstract
OBJECTIVES The aim of this study was to demonstrate the first-in-human feasibility and short-term clinical outcomes with a new balloon-expandable transcatheter heart valve (THV). BACKGROUND The SAPIEN 3 (S3) THV incorporates a paravalvular sealing system, an active 3-dimensional coaxial positioning catheter, and is compatible with a 14-F expandable sheath. METHODS The S3 THV was implanted in 15 patients with symptomatic severe aortic stenosis via femoral arterial access. Multidetector computed tomography before and after valve implantation allowed assessment of a novel annular area sizing algorithm. Clinical and echocardiographic data were obtained at baseline, discharge, and 30 days. RESULTS All 15 device implants were successful. Multidetector computed tomography estimated an aortic annular area of 4.9 ± 0.4 cm(2), predicting 9.7 ± 6.9% THV oversizing. Post-transcatheter aortic valve replacement multidetector computed tomography showed consistently symmetrical and circular THVs. Aortic valve area increased from 0.7 ± 0.2 cm(2) to 1.5 ± 0.2 cm(2) (p < 0.001), and mean transaortic gradient decreased from 42.2 ± 10.3 mm Hg to 11.9 ± 5.3 mm Hg (p < 0.001). No patient had more than mild paravalvular aortic regurgitation. Hospital discharge occurred at a median of 3 (range 2 to 12) hospital days. At 30 days there were no deaths, strokes, vascular complications, bleeds, or transfusions, although 1 patient (6.7%) required a new pacemaker. All patients were in New York Heart Association functional class I or II. CONCLUSIONS The S3 THV and delivery system might facilitate fully percutaneous implantation in a broader range of patients with the potential for more accurate positioning and less paravalvular regurgitation.

Abstract
OBJECTIVES This study sought to evaluate, through a systematic review of the published data, the main baseline characteristics, management, and clinical outcomes of patients suffering coronary obstruction as a complication of transcatheter aortic valve implantation (TAVI). BACKGROUND Very few data exist on coronary obstruction after TAVI. METHODS Studies published between 2002 and 2012, with regard to coronary obstruction as a complication of TAVI, were identified with a systematic electronic search. Only the studies reporting data on the main baseline and procedural characteristics, management of the complication, and clinical outcomes were analyzed. RESULTS A total of 18 publications describing 24 patients were identified. Most (83%) patients were women, with a mean age of 83 ± 7 years and a mean logistic European System for Cardiac Operative Risk Evaluation score of 25.1 ± 12.0%. Mean left coronary artery (LCA) ostium height and aortic root width were 10.3 ± 1.6 mm and 27.8 ± 2.8 mm, respectively. Most patients (88%) had received a balloon-expandable valve, and coronary obstruction occurred more frequently in the LCA (88%). Percutaneous coronary intervention was attempted in 23 cases (95.8%) and was successful in all but 2 patients (91.3%). At 30-day follow-up, there were no cases of stent thrombosis or repeat revascularization, and the mortality rate was 8.3%. CONCLUSIONS Reported cases of coronary obstruction after TAVI occurred more frequently in women, in patients receiving a balloon-expandable valve, and the LCA was the most commonly involved artery. Percutaneous coronary intervention was a feasible and successful treatment in most cases. Continuous efforts should be made to identify the factors associated with this life-threatening complication to implement the appropriate measures for its prevention.

Abstract
OBJECTIVE To determine the impact of perioperative thoracic epidural analgesia (TEA) on acute and late outcomes following transapical transcatheter aortic valve implantation (TA-TAVI). PATIENTS AND INTERVENTION A total of 135 consecutive patients who underwent TA-TAVI were included. All patients received catheter-based pain control, either via TEA (TEA group, n=74) or intercostal local analgesia with a catheter placed at the surgical incision site (non-TEA group, n=61), depending on the preference of the anaesthesiologist responsible for the case. MAIN OUTCOME MEASURES Pain level during early postoperative period (verbal rating scale from 1 to 10), 30-day/in-hospital complications and mortality, and 1-year mortality. RESULTS There were no differences in baseline or procedural characteristics between groups except for a lower left ventricular ejection fraction in the TEA group. The maximal pain score related to thoracotomy in the postoperative period was higher in the non-TEA group as compared with the TEA group (4 (IQR: 3-5)) vs 2 (IQR: 1-3), p<0.001). Non-TEA was associated with a higher rate of pulmonary complications (p<0.05 for nosocomial pneumonia, reintubation and tracheostomy). The 30-day/in-hospital mortality rate was higher in the non-TEA group (22.9% vs 2.7% in the TEA group, p<0.001). At 1-year follow-up, overall mortality remained higher in the non-TEA group (31.1%) compared with the TEA group (10.8%), p=0.005. Similar periprocedural and late results were obtained in a propensity score-matched analysis that included 100 matched patients. In the multivariable analysis, STS score (p=0.027) and absence of TEA (p=0.039) were independent predictors of increased cumulative late mortality. CONCLUSIONS TEA provided superior analgesia following TA-TAVI, and was associated with a dramatic reduction in periprocedural respiratory complications, and both, short- and long-term mortality. These results highlight the importance of obtaining optimal analgesia following TA-TAVI to improve the results associated with this procedure.

Abstract
In transcatheter aortic valve implantation procedures using balloon-expandable valves, the valve is deployed by rapid balloon inflation within a short period of rapid ventricular pacing. This system and deployment technique is generally considered to be nonrepositionable. We illustrate with two cases (transapical and transfemoral) the possibility to partially reposition the valve during its deployment if a slow balloon inflation technique were employed-a technique that may minimize the risk of valve mal-positioning and its attendant complications.

Abstract
Transaortic transcatheter aortic valve implantation (TAo-TAVI) has been recently proposed as an alternative to transapical (TA) and transfemoral (TF) approach. We now discuss a technical issue associated with TAo-TAVI related to the use of a delivery system dedicated to the antegrade TA approach. The potential solutions to this issue as well as the potential advantages of the TAo approach are discussed.

Abstract
Sedentary and trained men respond differently to the same intensity of exercise, this is probably related to their platelet reactivity and antioxidant capacity. There is growing interest in the utilization of antioxidant-rich plant extracts as dietary food supplements. The aim of this study was to investigate the effect of an acute bout of sub maximal exercise on platelet count and differential response of platelet activation in trained and sedentary subjects and to observe if cocoa polyphenols reverse the effect of exercise on platelet function. The practical significance of this study was that many sedentary people engage in occasional strenuous exercise that may predispose them to risk of heart disease. Fasting blood samples were collected from 16 male subjects, pre and post 1-h cycling exercise at 70% of maximal aerobic power (VO2max) before and after consumption of cocoa or placebo. Agonist stimulated citrated whole blood was utilized for measuring platelet aggregation, adenosine triphosphate (ATP) release and platelet activation. Baseline platelet count (221 +/- 33 x 10(9)/L) and ATP release (1.4 +/- 0.6 nmol) increased significantly (P < 0.05) after exercise in all subjects. Baseline platelet numbers in the trained were higher (P < 0.05) than in the sedentary (235 +/- 37 vs. 208 +/- 34 x 10(9)/L), where as platelet activation in trained was lower (P < 0.05) than sedentary (51 +/- 6 vs. 59 +/- 5%). Seven days of cocoa polyphenol supplementation had little effect on any of the parameters measured. We conclude that trained subjects show decreased activation of stimulated platelets when compared to the sedentary subjects and short-term cocoa polyphenol supplementation did not decrease platelet activity in response to exercise independent of prior training status.

Abstract
Previous studies have shown that prolonged propagation of undifferentiated human embryonic stem cells (hESCs) requires conditioned medium from mouse embryonic feeders (MEF-CM) as well as matrix components. Because hESCs express growth factor receptors, including those for basic fibroblast growth factor (bFGF), stem cell factor (SCF), and fetal liver tyrosine kinase-3 ligand (Flt3L), we evaluated these and other growth factors for their ability to maintain undifferentiated hESCs in the absence of conditioned medium. We found cultures maintained in bFGF alone or in combination with other factors showed characteristics similar to MEF-CM control cultures, including morphology, surface marker and transcription factor expression, telomerase activity, differentiation, and karyotypic stability. In contrast, cells in media containing Flt-3L, thrombopoietin, and SCF, individually or in combination, showed almost complete differentiation after 6 weeks in culture. These data demonstrate that hESCs can be maintained in nonconditioned medium using growth factors.

Abstract
The human telomerase reverse transcriptase (hTERT) promoter is known to selectively drive transgene expression in many human cancer cells expressing hTERT, the catalytic component of the telomerase ribonucleoprotein complex. We have created a conditionally replicative adenovirus where the viral E1A gene, which is required for viral replication, is under the control of the hTERT promoter (AdhTERTp-E1A). In vitro studies with AdhTERTp-E1A virus on a variety of normal and tumor cell lines have shown that viral genome replication and productive infection is primarily restricted to telomerase-positive tumor cells. Lytic replication was not observed in normal primary fibroblast and epithelial cell lines tested. In vivo administration of the virus into nude mice bearing human liver or prostate tumor xenografts produced significant tumor reduction and, in some cases, resulted in complete tumor regression. AdhTERTp-E1A virus did not actively express E1A in normal mouse liver, in contrast to a control oncolytic vector in which the CMV promoter (AdCMVp-E1A) was driving the E1A gene. In addition, AdhTERTp-E1A virus produced no apparent toxicity to the liver in systemically injected mice. The hTERT promoter-driven oncolytic virus also produced significantly less toxicity to freshly cultured human hepatocytes. These studies demonstrate that an oncolytic virus driven by the telomerase promoter can be used to effectively kill a wide variety of cancer cell types and has the potential to treat primary and metastatic cancer of diverse origins.

Abstract
This overview of Rasch measurement models begins with a conceptualization of our continuous experiences that are often captured as discrete observations. It goes on to discuss the properties that are require of measures if they are to transcend the occasion in which they were collected, and concludes with a discussion the spiral of inferential development. This is followed by a discussion of the mathematical properties of the Rasch family of models that allow the transformation of discrete deterministic counts into continuous probabilistic abstractions on which science is based. The overview concludes with a discussion of six of the family of Rasch models, Binomial Trials, Poisson Counts, Rating Scale, Partial Credit, and Ranks and the types of data for which these models are appropriate.

Abstract
We conducted a six-month prospective interventional crossover study examining a computerized diabetes monitoring system (DMS) that conveyed dietary information. The objectives were to compare glycaemic control between intervention and control periods, and to assess patients' acceptance of the DMS. Nineteen patients were randomized into two groups, each using the DMS for three months and serving as the control group for another three months. The patients recorded information about their meal portions and blood glucose readings in a hand-held electronic diary. After transmitting the data to the DMS through a telephone modem, the patients received immediate feedback about the carbohydrate, protein and fat content of the meal, as well as the calorie content. A significant improvement in glycaemic control was achieved during intervention compared with control periods (mean HbA1C reduction of 0.825%). The DMS was also highly acceptable: 95% patients found it easy to operate while 63% found it useful. The DMS was thus a feasible model of telemedicine in diabetes care and a larger study is warranted to examine its cost-effectiveness.

Abstract
This study provides a profile of injuries sustained by Little Athletes and the injury prevention strategies they employed. The sample comprised 388 registered Little Athletes from seven Sydney New South Wales Clubs. Results from the survey and fieldwork suggested that at least one out of five Little Athletes had one or more injuries resulting from their participation in the current season. However, athletes aged under 11 to under 15 years were more likely to be injured than those in the younger age groups. The older athletes were also likely to have sustained more than four injuries during the season. Athletes reported low use of both warm up and warm down methods. Coaches, age managers and parents were portrayed as the key providers of information concerning injury prevention strategies. It was therefore noted that a valuable opportunity exists to create and design an innovative, age progressive educational package for Little Athletes, parents and coaches.

Abstract
This paper discusses the dispersal of facilities where family members migrate to different destination countries. Terminology for internationally dispersed families is proposed, and the term branch migration is suggested for the migration of related people from the same source country to different destination countries. Data from two 1993 surveys of senior secondary students show that 22% of Sydney students and 20% of Hong Kong students have relatives in two or more other countries. The data suggest that many Asian migrant families have branched between the US, Canada, Australia and other migrant-receiving nations. The causes and implications of the international dispersal of families are discussed.

Abstract
Hyponatremia is a common clinical entity which may occur during the course of many medical illnesses. However disastrous sequelae or even death may develop in young, generally healthy patients who receive simple elective surgery. Here we present a case of a 34-year-old female, without past history of cardiopulmonary or renal disease, after undergoing laparoscopic surgery developed mental status changes and lapsed into coma on the second postoperative day. She was found to have a serum sodium level of 110 mEq/L. After careful treatment and a protracted hospital stay, the patient recovered uneventfully. The pathophysiology of postoperative hyponatremia is discussed and attention is called to the special vulnerability of menstruant women who carry a much increased risk of mortality and morbidity associated with hyponatremia.
