    Notes: Improvement in left ventricular assist device (LVAD) implantation techniques may favorably impact on the significant perioperative morbidity and mortality that follows placement of these devices. Based on the difficulties faced and complications encountered during our 45 case experience, we developed a quick-reference illustrated guide which outlines in detail the steps and considerations critical for successful LVAD implantation.

    Notes: Abstract  Background: The presence of significant left main stenosis (≥50%) has been considered a relative contraindication to the use of off-pump coronary artery bypass (OPCAB) stemming from well-documented hemodynamic perturbations during the displacement of the heart. We examined our experience with patients with critical left main stenosis (LMS) to assess the safety and feasibility of OPCAB in this subgroup. Methods: Our prospectively updated database was queried to identify all patients with severe left main disease who underwent isolated coronary revascularization between January 1, 1999 and May 31, 2002. This query yielded 234 on-pump and 420 off-pump patients with significant LMS whose clinical information was retrospectively reviewed. Results: The groups were well matched with regard to gender, left ventricular function, surgical priority, and severity of angina. The conventional coronary artery bypass (CABG) group was significantly younger than the OPCAB group and had a higher incidence of a previous myocardial infarction. Patients in the CABG cohort were more likely than OPCAB patients to remain ventilated after 24 hours, require placement of intraoperative or postoperative intraaortic balloon pump, or suffer from postoperative renal failure. There was a decrease in mortality (6.4% vs. 1.9%; p = 0.006) when CPB was eliminated. Intermediate term survival analysis revealed a significant survival benefit in the off-pump group (p = 0.007). Conclusions: Multivessel off-pump revascularization in patients with severe left main disease is a safe and effective alternative to conventional bypass grafting and conveys a survival benefit.

Bernal knew all along: that protein structure was the key to biology, and the advent of structural genomics must be celebrated as the real beginning of making ...

    Outpatient Pacemaker Procedures in Orally Anticoagulated Patients (1998)
    Oxford, UK : Blackwell Publishing Ltd
    Pacing and clinical electrophysiology 21 (1998), S. 0 
    Details

    Notes: Reexamination of surgical practices in the present era of cost containment has led to increased outpatient procedures including pacemaker surgery. While the safety and economic benefits of outpatient pacemaker surgery in nonanticoagulated patients is well documented, results of pacemaker operations in patients maintained on coumadin for thromboembolic prophylaxis have not been evaluated. In patients where complications with pacemaker surgery appeared successive, we have established a low incidence of complications. Recently, we extended this approach to the outpatient setting; this report retrospectively reviews our 4-year experience. During the study period, 150 patients underwent outpatient pacemaker procedures, including 37 patients receiving oral warfarin. There was no difference in the incidence of wound related and wound unrelated complications between patients receiving warfarin and the nonanticoagulated cohort. In addition, no wound hematomas, blood transfusions, or clinically significant bleeding episodes were noted among warfarin recipients. We conclude that pacemaker surgery in patients receiving oral anticoagulation is safe and feasible. The use of the cephalic cutdown technique avoiding blind subclavian punctures, meticulous attention to pocket hemostasis, and the use of small caliber unipolar positive fixation leads appears warranted in this selected group of patients at high risk for perioperative bleeding.

    Effect of temperature on morphology and DNA-content of polytene chromosomes in Drosophila (1979)

    Notes: Abstract Feulgen-DNA contents and chromosome lengths and projected areas were measured in salivary gland nuclei from Drosophila prepupae which had developed at 25° or 15° C. Nuclei from a given prepupa fell into 3 to 5 DNA classes corresponding to different levels of polyteny. The 15° nuclei tended to fall into higher classes than those from 25°-reared animals, and their chromosomes were, on average, about 50% wider. Chromosomes within a given DNA class did not differ significantly in mean area, length or width between the temperature groups, and slight apparent differences in mean DNA content were attributable to systematic microdensitometric errors associated with differences in the spreading behaviour of the nuclei. On cytological examination, chromosomes from the two temperature groups differed mainly in width and stain intensity, but some other differences in appearance could not be accounted for by levels of polyteny. The mean length of the chromosome complement was about 400 μm. From one polytenic level to the next the chromosomes increased by about 10% in length, 40% in width and 17% in mean absorbance. The DNA content approximately doubled; small apparent deviations from the 1∶2 ratio could have been due to microdensitometric error or to underreplication of heterochromatin.

    Notes: Abstract Third World countries should exploit the genetic information stored in their flora and fauna to develop independent and highly competitive biotechnological and pharmaceutical industries. The necessary condition for this policy to succeed is the reshaping of their universities and hospitals—to turn them into high-caliber research institutions dedicated to the creation of original knowledge and biomedical invention. Part of the service of the Third World foreign debt should be co-invested with the lending banks in high technology enterprises. This should be complemented with an active program of investments in First World biotech companies and university research departments which could contribute to the solving of problems connected with the First World. These strategic alliances would allow effective training of molecular biologists, improvement of South American universities, and education of biotechnologists, managers, and lawyers in the complexities of high-technology business. The establishment of real joint ventures between developed and underdeveloped countries might contribute to change the present strained relations between the North and the South, and science and technology could become real forces of social and economic development.

    Notes: Abstract Third World countries are not pursuing scientific and technological policies leading to the development of strong biotechnological industries. Their leaders have been misled into believing that modern biotechnological industries can be built in the absence of strong, intellectually aggressive, and original scientific schools. Hence, they do not strive to reform their universities, which have weak commitments to research, and do not see the importance of having research hospitals able to generate excellent and relevant clinical investigation. These strategic gaps in scientific capability, the lack of governmental and corporate research funding, and the dependent nature of the chemical and pharmaceutical industries of the Third World make the development of competitive biotechnology a highly improbable event. If the present trend continues, underdeveloped countries will continue to be testing grounds for biological materials and agents, sources of valuable germplasm, and markets for high-value-added products and processes invented and manufactured in the First World. This article recommends that the international organizations collaborate in the urgent task of educating the Third World political leaders and administrators in the real problems connected with the generation of high technology.
