Full textThe aim was to study pathophysiological mechanisms and risk factors for developing atrial fibrillation (AF) after coronary artery bypass grafting (CABG), and the effect of thoracic epidural anaesthesia (TEA).
The study comprised 141 patients undergoing CABG, including 45 patients randomised for TEA intra- and postoperatively. All patients underwent 24-hour Holter monitoring pre- and postoperatively for the analysis of arrhythmias and heart rate variability (HRV). Catecholamines and neuropeptides (reflecting sympathetic and parasympathetic activity), atrial peptides and echocardiographically assessed atrial arias were obtained pre- and postoperatively.
Logistic regression analysis identified body mass index (BMI), maximum supraventricular beats (SPB) per minute, and total amount of cardioplegia as independent predictors of postoperative AF. Patients developing AF showed limited diurnal variation of HRV preoperatively. All HRV parameters decreased significantly in all patients postoperatively. The significant postoperative increase in atrial areas and atrial peptides did not differ between patients developing AF and those who did not. TEA had no effect on the incidence of postoperative AF, but resulted in lower heart rate, less increase in adrenaline levels, and decreased neuropeptide levels (reflecting sympathetic and parasympathetic activity). AF was initiated by an SPB in 72.4% of non-TEA and 100% of TEA treated patients, whereas changes in heart rate only, before onset, were seen in 17.2% non-TEA patients.
The observed risk factors, SPB and cardioplegia, may both induce electrophysiological changes known to increase the susceptibility to AF. The observed postoperative atrial dilatation and autonomic imbalance, indicated by HRV and neuropeptide levels, may further favour the development of AF. The observation that a majority of postoperative AF was initiated by a premature atrial contraction supports our hypothesis that latent atrial foci may be a major trigger mechanism of postoperative AF.

Full textBackground: Heart surgery can save a patient's life but can also lead to an increased risk of suffering from a complication such as postoperative delirium. Delirium is not an illness but a state of mental confusion that affects the patient's attention, awareness and cognitive ability. Postoperative delirium can lead to many negative consequences which can cause patient suffering. Nursing care has aimed to alleviate a patient's suffering by seeing the entire patient in the caring relationship. This is the core in nursing science. Research has shown that it is important for the patient's postoperative recovery to be able to detect and prevent postoperative delirium in an early stage. It has appeared that intensive care nurses need more education and knowledge in this area in order to be able to detect and prevent postoperative delirium after heart surgery. Aim: The aim of the study is to identify risk factors that are associated with the development of postoperative delirium after heart surgery within patients in the intensive care unit. Method: A systematic literature review that analyzed quantitative articles according to a method of analysis by Bettany-Saltikov and McSherry (2016). Result: Four categories emerged from the analysis: Patients background, length of mechanical ventilation, Heart- and lung machine duration and Complications after heart surgery that were risk factors which affected the development of postoperative delirium. Conclusion: The overall knowledge that the study has provided can form a basis for intensive care nurses in the care of patients with postoperative delirium. Further research is needed on risk factors for postoperative delirium and how the mental confusion affects both the patient and relatives. More research is also needed about how postoperative delirium can be prevented.

Full textOver the last decade there has been a significant increase in volume of spinal surgeries performed as well as in medical and surgical complexity of patients. This was accompanied by an increased overall morbidity and volume of complications. At the same time, health care professionals have become more aware of the impact of specific preventable complications such as surgical site infections (SSI) and huge efforts have been directed to reduce SSI incidence. Although the general risk factors for SSI have been discussed, the relationship of neurologic status and trauma to SSI has not been explicitly explored. In addition, the direct and indirect impact of deep SSI on surgical outcomes especially after adult spinal deformity (ASD) surgery is still unclear. The aim of this doctoral thesis is to review the risk factors for developing a SSI after spine surgery, as well as how SSI affects clinical outcome. It mainly focuses on diagnosis (Traumatic vs. Degenerative) and neurological status (Spinal Cord Injury SCI or Myelopathy MP) as predictors for SSI. It also reports the associated morbidities and costs of SSI and evaluates the surgical outcomes after SSI. The National Inpatient Survey (NIS) and the Thomas Jefferson University Hospital (TJUH) databases were probed to analyse infection in patients with primary cervical surgery. Using a multivariate analysis, all interplaying comorbidities and risk factors have been. A subsequent resource utilization analysis has been done. The European Spine Study Group (ESSG) prospective database was used to study the functional and clinical outcomes of SSI in patients with posterior fusion for Adult Spinal Deformity (ASD) through the comparison of matched cohorts. Readmissions, reoperations, deformity correction and fusion rates were also studied. A total of 1,247,281 and 5,540 patients met inclusion criteria in the NIS and TJUH databases respectively. SSI incidence was 0.73% (NIS) versus 1.75% (TJUH). It increased steadily from 0.52% in patients without MP to 1.97% in the traumatic SCI group in the NIS data and from 0.88% to 5.54% in the TJUH. Differences between diagnostic groups and cohorts reached statistical significance. SSI was predicted significantly by neurological status (odds ratio [OR] 1.69, p<.0001) and trauma (OR 1.30, p=.0003) in the NIS data. Other significant predictors included: approach, number of levels fused, female gender, black race, medium size hospital, rural hospital, large hospital, western US hospital and Medicare coverage. In TJUH, only trauma (OR 2.11, p=.03) reached significance when accounting for comorbidities. Costs of infection varied among diagnostic groups and summed $184060 in the SCI group. Patients with SSI were also more likely to be discharged to specialized institutions. 444 surgical ASD patients with more than 2 years of follow-up were identified. 20 sustained an acute SSI and 60 controls were accordingly matched. No differences were observed between groups in preoperative radiological and HRQoL variables confirming comparable groups. SSI patients had longer hospital stay and more mechanical complications including proximal junctional kyphosis. Infection was associated with more unrelated complications and revisions. Deformity correction was maintained equally at the different time intervals. One death was related to SSI. SSI patients had worse overall HRQoL status at 1 year and were less likely to experience improvement. However, no significant differences were recorded thereafter. As a conclusion, both primary diagnosis (trauma vs. degenerative) and neurologic status (MP or SCI) were found to be strong and independent predictors of SSI in cervical spine surgery. Also, SSI significantly affects the first postoperative year after posterior ASD surgery. It is associated with more complications, unrelated revisions, and worst quality of life. However it's negative impact seems to be diluted by the second postoperative year.

Full textCardiovascular diseases (CVDs) are among one of the well documented conditions and pose a significant health burden in the world as they areconsidered to be of adult onset. However, recent studies have shown that in developed countries CVD risk factors are becoming prevalent in young people which isof great concern. Therefore, the aim of this study was to determine if CVD risk factors are present in young subjects aged 15-20 years of age residing in a rural area of a developing country. Methods: Subjects aged between 15-20 years who participated in the “Gene - Environment interaction project” were included in this sub-study. Total cholesterol, triglycerides, HDL-cholesterol, LDLcholesterol, insulin, glucose, creatinine, Lp(a), apoB, apoA-1 and hs-CRPwere determined. Blood pressure, physical activity (number of steps/day), weight, height, waist circumference and hip circumference were obtained from the database. Subjects with CRP levels above 10mg/L and creatinine levels above 130 mmol/L were excluded. Results: The present study showed an overall high prevalence of some CVD risk factors. There was high prevalence of insulin resistance (23.0% in females and 34.7% in males), and high hs-CRP (18.4% in females, 12.9% in males). The prevalence of low HDL-C levels was high (55.2% in females and 16.8 % in males), however, the prevalence of abnormal levels of other lipids such as total cholesterol/HDL-cholesterol ratio was low in both males and females. The prevalence of an increased apoB/apoA ratio was significantly higher in females 26.4% compared to males 7.9%. The prevalence of overweight (12.6%) and obesity (9.2%) was higher in females than in males (overweight 1%, obesity 0 %). The prevalence of hypertension was comparable between the two genders (5.7% in females and 10.9 % in males). Conclusion: The results showed a relatively high prevalence of non-traditional risk factors for cardiovascular diseases in adolescents residing in a rural area, Limpopo Province, while the prevalence of traditional risk factors such as total cholesterol and triglycerides was low.

Full textCadre de l'étude: Certains sous-groupes de patients atteints de maladies inflammatoires de l'intestin (MII) peuvent courir un risque accru de développer un lymphome. Nous avons chercher à identifier les facteurs associés avec le lymphome chez les patients avec des MII. Méthodologie: Les cas et les témoins ont été identifiés à partir d'un répertoire de diagnostics centralisé. Nous avons identifié 80 patients adultes atteints de MII et qui ont dévelopé un lymphome confirmé par biopsie entre les années 1980-2009. Deux témoins étaient appariés pour chaque cas sur le sous-type de MII, la localisation géographique et la durée du suivi pour les MII dans notre centre jusqu'au diagnostic de lymphome. Les dossiers médicaux ont été consultés afin d'obtenir les données démographiques et cliniques. Un modèle de régression logistique conditionel a été utilisé pour évaluer les associations entre les facteurs de risque et le développement d'un lymphome. Résultats: Parmi les cas retenus, 60 étaient des hommes (75%) vs 77 dans le groupe de témoins (48%). L'âge médian à la date index était de 59 ans pour les cas et de 42 ans pour les témoins. Vingt cas (25%) et 23 témoins (14%) recevaient des médicaments immunosuppresseurs à la date index. Quatre cas (5%) et six témoins (4%) recevaient des anticorps antagonistes du TNF-alpha à la date index. Lors d'une analyse multivariée, l'age par décennie (rapport de cotes [RC]:1,83, intervalle de confiance à 95%[IC]: 1,37-2,43), le sexe masculin (RC:4,05, IC 95%:1,82-9,02) et l'exposition aux médicaments immunosuppresseurs à la date index (RC:4,20, IC 95%: 1,35-13,11) ont été associés, de façon significative, à un risque accru de developper un lymphome. La sévérité de la maladie et l'utilisation d'anticorps antagonistes du TNF-alpha n'ont pas été associés de manière indépendante au developpement d'un lymphome. Conclusion: Dans cette étude de cas-témoin, l'age avancé, le sexe masculin et l'tilisation de médicaments immunosuppresseurs ont été associés à un risque supérieur de lymphome chez les patients atteints de MII. Par contre, la sévérité de la maladie et l'utilisation des anticorps antagonistes du TNF-alpha n'ont pas été associés à un risque plus élevé.
