A dissertation submitted to the Faculty of Dentistry, University of the Witwatersrand, Johannesburg, in part- fulfilment of the requirements for the Degree of Master of Science in Dentistry 1982 / Rat embryos of the post-implantation stage are grown on a static culture medium, for the purpose of assessing growth and development over a 2 day period. The technique used is referred to as the petri-dish culture chamber method. This involves the culture of rat embryos on rat serum, in a controlled environment. Postimplantation embryos from the 6,5 to 8 day stage, and consisting simply of the 3 germ layers, showed a 60% survival rate in. vit/io after 2h hours and A8 hours respectively. After a full A8 hours in vitfio the embryos demonstrated well developed beating hearts, and a neural groove in the process of closing. The survival rate of embryos explanted at later stages was not as successful. The results compare favourably with the results of other workers, using the same method of culture. An advantage of the petri-dish culture chamber is that it allows for easy experimental access to the embryos at all times;a factor to be considered in any technique involving surgical intervention. Although more sophisticated methods have since superseded the static environment petri-dish technique, it is recommended here that this method should not be totally replaced by the more modern circulating culture medium technique. / IT2017

Methods We systematically searched for articles that assessed the prognostic role of diastolic dysfunction on cardiovascular surgery in PubMed, Cochrane Library, Web of Science, Embase and Scopus until February 2016. Twelve studies (n=8224) met our inclusion criteria. Due to scarcity of outcome events, fixed-effects meta-analysis was performed using the Mantel-Haenszel method. Results Preoperative diagnosis of diastolic dysfunction was associated with higher postoperative mortality (OR 2.41, 95% CI 1.54-3.71; p<0.0001), major adverse cardiac events (MACE) (OR 2.07, 95% CI 1.55-2.78; p <=0.0001) and prolonged mechanical ventilation (OR 2.08, 95% CI 1.04-4.16; p=0.04) in comparison to patients without diastolic dysfunction among patients who underwent cardiovascular surgery. The odds of postoperative myocardial infarction (OR: 1.29, 95% CI 0.82, 2.05; p=0.28) and atrial fibrillation (OR: 2.67; 95% CI 0.49-14.43; p=0.25) did not significantly differ between the two groups. Severity of preoperative diastolic dysfunction was associated with increased postoperative mortality (OR 21.22, 95% CI 3.74 -120.33; p=0.0006) for Grade 3 diastolic dysfunction compared with patients with normal diastolic function. Inclusion of left ventricular ejection fraction (LVEF) <40% accompanying diastolic dysfunction, did not further impact postoperative mortality (p=0.27; I2 =18%) when compared with patients with normal LVEF and diastolic dysfunction. Conclusions Presence of preoperative diastolic dysfunction was associated with higher postoperative mortality and MACE, regardless of LVEF. Mortality was significantly higher in grade III diastolic dysfunction. Keywords Diastolic dysfunction; cardiovascular surgical procedures; mortality; meta-analysis / Revisión por pares

Syfte: Att beskriva dagkirurgiska patienters upplevelse av att bli utskrivna hem samma dag efter operation utförd i generell anestesi. Metod: Kvalitativ intervjustudie med induktiv ansats. Elva patienter som har opererats via en handkirurgisk mottagning i mellersta Sverige har intervjuats utifrån en semistrukturerad intervjuguide. Sju kvinnor och fyra män i åldrarna mellan 28-71 år har deltagit i studien. Innehållsanalys användes för analys av materialet. Resultat: Patienterna upplevde hemgången som väldigt positiv. De faktorer som bidrog till en lyckad hemgång var framförallt; Patientens goda grundhälsa, en trygg hemmiljö att återvända till och återhämta sig i, samt att patienterna får sina frågor och funderingar besvarade inför hemgången, och stöd från anhöriga. Vårdpersonalens bemötande och professionella förhållningssätt bidrog till att patienterna upplevde en känsla av trygghet som skapade en förutsättning för delaktighet.  Resultatet visar även att patienter önskar mer information om det postoperativa förloppet. Slutsats: Att skrivas ut och komma hem efter ett dagkirurgiskt ingrepp är en positiv upplevelse för patienterna, dock behöver informationen inför hemgången samt möjligheten till stöd från den dagkirurgiska enheten efter hemgången förbättras. / Aim: To describe the day-surgery patients´ experience to be discharge the same day after surgery in general anesthesia. Methods: Qualitative interview study with inductive approach. Eleven patients, operated by a hand surgical receptions in central Sweden were interviewed, using a semi- structured interview guide. Seven women and four men between 28-71 years participated in the study. Content analysis was used for analysis of the material. Result: Patients experienced the discharge as very positive. The factors which contributed to a successful discharge was above all, patient good basic health, a safe home to return to and recover in, and that the patients have their questions and concerns answered before discharge, and the support from relatives. Health professionals' reception and professional approach helped the patients to feel a sense of security that created a condition for participation. The results also show that patients want more information about the postoperative recovery. Conclusions: To be discharged, and come home, after day surgery procedures is a positive experience for patients, however, the information at discharge and the possibility of support from the day surgery unit after discharge needs to improve.
