Published: October 2010

Objective Endoscopic radial artery harvesting (ERAH) has superior cosmetic advantages over conventional harvesting methods. With instrumental advancements, these techniques have become easier to adopt and require less time to learn. In most reported cases, the quality of harvested conduits is discussed based on macroscopic and histologic examinations and clinical outcomes. However, predischarge angiography gives a straightforward answer regarding quality of harvested conduit. The aim of this study is to assess the quality of endoscopically harvested radial artery by predischarge angiographic evaluation. Methods Endoscopic procedure using VasoView 4 system was performed in 87 patients between September 2004 and December 2007, and 78 predischarge angiographical evaluations were completed and reviewed. Mean age of the patients was 66 ± 10 years and 18% were women. After ERAH was performed, accompanying veins were dissected by ultrasound scalpel. All conduits were as aortocoronary bypass under cardiopulmonary bypass. Results Mean arm ischemic time was 32 ± 13 minutes and length of harvested conduit was 17.8 ± 1.3 cm. Predischarge angiography demonstrated two occlusions at the proximal anastomosis in the 51st and 71st cases, although intraoperative flow study showed normal flow patterns in both cases. Stenosis in the conduits was observed in the first, sixth, and seventh cases. No further angiographical problems were found in the remaining conduits. Conclusions Based on the angiographical results, problems with the harvested conduits occurred only in initial period. ERAH with VasoView system provides satisfactory angiographical quality after initial learning curve.

Objective The aim of this study was to histologically evaluate the importance of using buttressing materials in stapling the atrial appendages. Methods We stapled the right atrial appendage with a commercial apparatus in 11 mongrel dogs. To evaluate the efficiency of using a buttressing material as an adjunct to stapling, we conducted 30-day studies without (group A: n = 2) or with buttressing material (group B: n = 3) and 90-day studies without (group C: n = 3) or with buttressing material (group D: n = 3) and thereafter made assessments using Doppler echocardiography and performed histologic analyses on all stapled appendages. Results During surgery, blood oozing from the stapling sites was observed in four of five cases of groups A and C; with buttressing, there was no oozing in groups B and D. In groups A and B, we observed the myocardium of the appendage being focally replaced with fibrous tissue. Myocardium in group C was infiltrated diffusely with loose fibrous tissue and in group D had been almost completely replaced with fibrous tissue. Conclusions The buttressing material was useful not only in preventing oozing but also likely promoting the growth of fibrous tissue in the right atrial appendage.

Objective To define the role and early results of aortic valve surgery through a right minithoracotomy. Methods A retrospective analysis was performed on 306 consecutive patients undergoing aortic valve replacement through an 8-cm right minithoracotomy in the second intercostal space. The initial experience was included. The right second and third ribs were detached from the sternum in most cases and repaired at the end of each case. Most operations were performed using anterograde and retrograde cardioplegic arrest with percutaneous femoral venous cannulation and direct aortic cannulation through the incision. Standard instruments were used with direct digital knot tying. Results Mean age was 65 ± 14 (range, 20–90) years. Aortic valve disease cause was calcific disease in 160 of 306 (52%) patients, bicuspid disease in 95 of 306 (31%) patients, and endocarditis in 9 of 306 (3%) patients. Previous cardiac surgery was present in 13 of 306 (4%) patients. Biologic prostheses were used in 240 of 306 (78%) patients. Median valve size was 23 mm. Mean clamp times and pump times were 103 ± 26 and 158 ± 35 minutes, respectively. Median postoperative length of stay was 5 days. Thirty-day mortality was found in 4 of 306 (1%) cases. There were no deep wound infections or mediastinitis. Stroke occurred in 5 of 306 (1.6%) patients, and new pacemaker required in 11 of 306 (4%) patients. Reoperation for bleeding occurred in 2 of 306 (1%) patients. Conversion to median sternotomy occurred in 15 of 306 (5%) patients caused by chest wall anatomy (n = 7), bleeding (n = 3), coronary disease (n = 2), or aortic disease (n = 3). Patients were allowed to return to driving or preoperative activity in 2 weeks. With a mean follow-up of 2.8 ± 2.2 years, one patient required reoperation for aortic root disease. Conclusions Right minithoracotomy is a safe but limited alternative to sternotomy in isolated aortic valve replacement. This approach may be particularly valuable in some higher risk, elderly patients and opens options for a hybrid approach combined with percutaneous coronary angioplasty.

Objective Adequate stabilization of anastomosis sites during off-pump coronary artery bypass is essential to obtain excellent graft patency. We examined the effect of beta-1 adrenergic receptor blockade on the target coronary artery motion by three-dimensional (3D) digital motion capture and reconstruction technology. Methods Eight pigs underwent a sternotomy. Reflection markers were attached to the surface coronary arteries, followed by a mechanical stabilizer application. Two high-speed digital cameras captured two-dimensional (2D) motion of the markers from different angles. These 2D data were reconstructed into 3D data points, representing the motion of each coronary artery. Landiolol hydrochloride, a novel selective beta-1 receptor blocker, was infused intravenously after acquisition of control data. Results Beta-1 receptor blockade decreased heart rate (105 ± 16 vs. 90 ± 9 beat/min; P = 0.007) without decreasing arterial blood pressure. The 3D distance moved (millimeter) during one cardiac cycle was significantly reduced on the left anterior descending (9.6 ± 2.8 vs. 6.6 ± 1.9 mm; P = 0.003), left circumflex (10.5 ± 6.3 vs. 6.4 ± 2.6 mm; P = 0.038), and right coronary (8.3 ± 3.6 vs. 6.5 ± 2.1 mm; P = 0.028) arteries. Reduction in the maximal velocity, maximal acceleration, and maximal deceleration of the anastomosis site in all coronary arteries was also found in a quantitative fashion. Conclusions Selective beta-1 receptor blockade significantly reduces the 3D motion at anastomosis sites on the beating heart, with stable systemic blood pressure. Further quantitative investigations of pharmacological stabilization are warranted to achieve better outcome of the patients undergoing off-pump coronary artery bypass surgery.

Objective Robotics-assisted endoscopic atraumatic coronary artery bypass has been shown to be effective in reducing surgical morbidity and length of hospital stay. Unfortunately, the criteria for selecting eligible patients for this procedure are still primitive. This has motivated the use of preoperative computed tomography scans to establish patient eligibility. The objective of this study is to establish which image measurements can be correlated to procedure success. Methods A retrospective study was performed in 144 patients who underwent robotics-assisted coronary bypass surgery. After an initial set of 55 patients, preoperative computed tomography scans of the other patients were used to obtain patient specific measurements: the lateral distance between the midline of the sternum to the left anterior descending coronary artery and its depth from the skin surface, anteroposterior diameter of the thoracic cavity, and the transverse diameter of the thoracic cavity. The procedures were rated as successful if completed in a minimally invasive manner. Different combinations of the variables were evaluated and correlated with success. Results A strong correlation was found between success rate and the ratio of the lateral distance to the transverse diameter in the female patients only (0.532, P = 0.006). A ratio of less than 0.20 significantly increased the occurrence of conversion during this procedure in female cases. Conclusions The lateral distance of the left anterior descending coronary artery from the midline divided by the transverse thoracic width of a female patient shows a significant correlation with procedure success. No significant correlations were found for male patients.

AbstractThe abscission process is initiated by changes in the auxin gradient across the abscission zone (AZ) and is triggered by ethylene. Although changes in gene expression have been correlated with the ethylene-mediated execution of abscission, there is almost no information on the molecular and biochemical basis of the increased AZ sensitivity to ethylene. We examined transcriptome changes in the tomato (Solanum lycopersicum ‘Shiran 1335’) flower AZ during the rapid acquisition of ethylene sensitivity following flower removal, which depletes the AZ from auxin, with or without preexposure to 1-methylcyclopropene or application of indole-3-acetic acid after flower removal. Microarray analysis using the Affymetrix Tomato GeneChip revealed changes in expression, occurring prior to and during pedicel abscission, of many genes with possible regulatory functions. They included a range of auxin- and ethylene-related transcription factors, other transcription factors and regulatory genes that are transiently induced early, 2 h after flower removal, and a set of novel AZ-specific genes. All gene expressions initiated by flower removal and leading to pedicel abscission were inhibited by indole-3-acetic acid application, while 1-methylcyclopropene pretreatment inhibited only the ethylene-induced expressions, including those induced by wound-associated ethylene signals. These results confirm our hypothesis that acquisition of ethylene sensitivity in the AZ is associated with altered expression of auxin-regulated genes resulting from auxin depletion. Our results shed light on the regulatory control of abscission at the molecular level and further expand our knowledge of auxin-ethylene cross talk during the initial controlling stages of the process.

Published: October 2010

Aliment Pharmacol Ther 2010; 32: 1297–1306SummaryBackground  Patients with ulcerative colitis (UC) that is chronically active despite 5‐aminosalicylates or immunomodulators, or who are dependent on corticosteroids to maintain remission, have limited treatment options. Granulocyte/monocyte adsorptive apheresis (GMAA) may have a role in this situation.Aim  To conduct a systematic review of GMAA in UC.Methods  MEDLINE, EMBASE and the Cochrane central register of controlled trials were searched to identify randomized controlled trials (RCTs) comparing GMAA with conventional medical therapy, sham procedure or ‘intensive’ with ‘conventional’ GMAA regimens in adult UC patients. Studies reported clinical remission or response rates.Results  Ten RCTs were eligible. Formal meta‐analysis was not undertaken due to concerns about methodological quality of identified studies. Compared with medical therapy, remission rates with GMAA were generally higher, and corticosteroid‐sparing effects were observed. Compared with sham procedure, GMAA did not achieve significantly higher remission rates. ‘Intensive’ GMAA regimens demonstrated generally higher remission rates, and time to remission was shorter compared with ‘conventional’ regimens. Only two RCTs were at low risk of bias. Six were conducted in Japanese patients, which may limit generalizability.Conclusions  Granulocyte/monocyte adsorptive apheresis appears of some benefit in UC. High‐quality RCTs comparing granulocyte/monocyte adsorptive apheresis with conventional medical therapy or sham procedure in Western populations, with disease activity confirmed endoscopically, are required.
Effects of female feeding regime in a sexually cannibalistic mantid: fecundity, cannibalism, and male response inStagmomantis limbata(Mantodea)

1. Female feeding regime exhibited a cascade of effects on reproductive biology and behaviour in the mantidStagmomantis limbata(Hahn).2. Well‐fed females (High diet) consistently attained greater body mass, thicker abdomens, and higher fecundity than food‐limited females (Low diet) in four annual generations. Dorso‐ventral abdominal thickness strongly correlated with fecundity.3. In an experiment in captivity, Low diet females were more likely to cannibalize males than High diet females.4. High diet females attracted more males than Low diet females in several contexts. In terms of long‐range attraction, caged High diet females attracted more males in the field. In terms of short‐range attraction, males preferentially mounted and copulated with High diet females in captive paired choice trials. In naturally‐occurring pairs in the field, a preference for females with thick abdomens was evident. These results point to two possible explanations: male choice for well‐fed females and state‐dependent female pheromone emission.5. Two years of field data indicate considerable variation in female feeding success, as measured by abdominal thickness. Average feeding success in nature appears to be relatively high, when comparing the rate of abdominal expansion in the field to captive females maintained on High diets.6. In the field, nearly all mounts and copulations occurred in September in both years, when female feeding success is expected to be high. If mating activity occurs during a window of high female feeding success, so as to reduce the risk of cannibalism for males, then the female feeding regime may be implicated in the phenology of mating activity in cannibalistic species.

Published: October 2010

AbstractPlankton sampling was conducted in the Baltic to obtain sprat larvae. Their individual drift patterns were back‐calculated using a hydrodynamic model. The modelled positions along the individual drift trajectories were subsequently used to provide insight into the environmental conditions experienced by the larvae. Autocorrelation analysis revealed that successive otolith increment widths of individual larvae were not independent. Otolith increment width was then modelled using two different generalized additive model (GAM) analyses (with and without autocorrelation), using environmental variables determined for each modelled individual larval position as explanatory variables. The results indicate that otolith growth was not only influenced by the density of potential prey but was controlled by a number of simultaneously acting environmental factors. The final model, not considering autocorrelation, explained more than 80% of the variance of otolith growth, with larval age as a factor variable showing the strongest significant impact on otolith growth. Otolith growth was further explained by statistically significant ambient environmental factors such as temperature, bottom depth, prey density and turbulence. The GAM analysis, taking autocorrelation into account, explained almost 98% of the variability, with the previous otolith increment showing the strongest significant effect. Larval age as well as ambient temperature and prey abundance also had a significant effect. An alternative approach applied individual‐based model (IBM) simulations on larval drift, feeding, growth and survival starting as exogenously feeding larvae at the back‐calculated positions. The IBM results revealed optimal growth conditions for more than 97% of the larvae, with a tendency for our IBM to slightly overestimate larval growth.
Influence of mesoscale eddies on ichthyoplankton assemblages in the Gulf of Alaska

Published: October 2010

AbstractMesoscale eddies (100–200 km in diameter) propagating along the shelf‐break in the Gulf of Alaska are ubiquitous and have been shown to influence the ecosystem, but their influence on ichthyoplankton species composition and diversity has not been described. Evidence for larval fish entrainment in these eddies was examined using data from a cruise in 2005 that sampled three eastern Gulf of Alaska mesoscale eddies, and sampling that compared shelf to slope ichthyoplankton assemblages in the northern Gulf of Alaska (2002–2004). Hierarchical cluster analysis of oceanographic data showed that stations grouped according to location within an eddy. Species hierarchical cluster analysis revealed a latitudinal turnover in species composition, and an abundant species group. Species richness was correlated with distance from eddy center (P = 0.00025), and assemblages within eddies were significantly different (P < 0.05) from those in surrounding basin and shelf waters. These results suggest that mesoscale eddies propagating along the continental shelf‐break influence larval fish assemblages over the shelf and slope, which has implications for the timing and extent of larval fish distribution in the Gulf of Alaska.

Published: October 2010

Aims.  The purpose of this study was to examine how prevention of complications for people with diabetes mellitus had been conducted, as described in their medical records, focusing particularly on sudden cardiac death. A further aim was to compare the documentation with guidelines for diabetes care.Background.  Diabetes mellitus is associated with an increased risk of cardiovascular disease, death and sudden cardiac death. About half of those affected by sudden cardiac death are assumed to have had one or more risk factors for cardiovascular disease that could have been treated effectively resulting in a reduced risk of sudden death.Design.  Survey.Method.  Fifty‐six people diagnosed with diabetes mellitus, who had died of a sudden cardiac arrest between the years 2003–2005, from the Northern Sweden MONICA myocardial registry were included. These people’s medical records were examined with regard to documentation of the care given during the year prior to the person’s sudden cardiac death.Results.  The qualitative content analysis resulted in four categories: individualised goals for diabetes care; prevention of complications; self‐care; and factors which may affect ability to adhere to treatment. The quantitative analysis showed that few people with diabetes mellitus achieved goals for metabolic control, compared with those set in guidelines for diabetes mellitus care.Conclusion.  To prevent complications for people with diabetes mellitus, it is a challenge for nurses and physicians to involve people with diabetes mellitus in their own care to improve the prognosis.Relevance to clinical practice.  Examination of medical records of people with diabetes mellitus showed that documentation could be more informative and systematic. It is important to achieve better adherence to treatment and to increase people’s understanding of their illness.

Aims.  The aim of this study is to evaluate the effectiveness of structured discharge education on maternal confidence and caring knowledge and the growth of premature newborns.Background.  Parents of premature newborns are usually confronted with great difficulties in caring for their babies after discharge. Building maternal confidence and caring knowledge can help mothers reduce such difficulties of caring for their babies after discharge from hospital.Design.  Randomised controlled trial.Methods.  Mothers with premature babies were randomly assigned into experimental (n = 29) and control groups (n = 30) at a medical centre in southern Taiwan. The mothers of both groups had received a questionnaire concerning maternal confidence and caring knowledge at pretest. After the pretest, a structured discharged education programme was provided to the mothers of the experimental group. The control group only received traditional discharge education. Mothers of experimental and control groups again received the questionnaire of maternal confidence and caring knowledge at the day before discharge and one month after discharge. At that time, the body height and body weight of newborns were measured and recorded.Results.  Maternal confidence and caring knowledge of mothers in the experimental group were significantly higher than those of the control group at the day before discharge; however, there were no significant differences between the two groups one month after discharge. Using repeated anova analysis, the time × group interaction was significant for maternal confidence and caring knowledge, indicating that the groups differed significantly in changes in maternal confidence and caring knowledge over the three time points.Conclusions.  Structured discharge education on mothers could significantly increase maternal confidence and caring knowledge at the day before discharge. Furthermore, structured discharge education could significantly increase the percentage of growth on body height of premature newborns.Relevance to clinical practice.  The results could help clinical nurses design appropriate discharge education programmes for mothers of premature newborns.
