The calcined aortic stenosis is one the most frequently occurring cardio-vascular diseases with unfavorable prognosis of course. The modern concepts about risk factors of development, pathogenesis and course of disease starting with inflammation and endothelial dysfunction and terminating with bone metaplasia permit determining prospective directions of deceleration of progression of calcined aortic stenosis. The high risk of unfavorable cardio-vascular occurrences associated with calcinosis of valvular apparatus of heart, availability of concomitant diseases making difficulties for correction of valvular impairments makes searching for causes of development and progression of ectopic calcification of aortic valve especially actual. The development of strategy of modification of risk factors and prevention of progression of early valvular impairments and blood circulation insufficiency are actual to the same extent. The review considers main clinical factors associated with development of calcined aortic stenosis, significance of genetic polymorphism in development of this heart disease and also main pathogenic mechanisms of its progressing.

AbstractThe loss of a pet can be particularly distressing for owners, whether the method of death is euthanasia or is unassisted. Using primary-care clinical data, this study aimed to report the demographic and clinical factors associated with euthanasia, relative to unassisted death, in dogs. Method of death (euthanasia or unassisted) and clinical cause of death were extracted from a random sample of 29,865 dogs within the VetCompass Programme from a sampling frame of 905,544 dogs under UK veterinary care in 2016. Multivariable logistic regression modelling was used to evaluate associations between risk factors and method of death. Of the confirmed deaths, 26,676 (89.3%) were euthanased and 2,487 (8.3%) died unassisted. After accounting for confounding factors, 6 grouped-level disorders had higher odds in euthanased dogs (than dogs that died unassisted), using neoplasia as the baseline. The disorders with greatest odds included: poor quality of life (OR 16.28), undesirable behaviour (OR 11.36) and spinal cord disorder (OR 6.00). Breed, larger bodyweight and increasing age were additional risk factors for euthanasia. The results highlight that a large majority of owners will face euthanasia decisions and these findings can support veterinarians and owners to better prepare for such an eventuality.

In recent years kernicterus at autopsy has been observed in sick premature infants in the absence of markedly elevated levels of serum bilirubin. Potentiating factors have been suggested to explain kernicterus in such a setting. In order to establish which factors are associated with increased risk for kernicterus in these small babies, this retrospective matched control study was undertaken. Thirty-two infants with kernicterus at autopsy were matched for gestational age, birth weight, length of survival, and year of birth to 32 control infants without kernicterus. Multiple historical, clinical, and laboratory factors were compared, including therapy, sepsis, hypothermia, asphyxia as reflected by Apgar score, hematocrit, acidosis, hypercarbia, hypoxia, hypoglycemia, and hyperbilirubinemia. No statistically significant differences between the kernicteric and nonkernicteric infants were demonstrated for any of these factors, including peak total serum bilirubin levels. Multivariant analysis also failed to determine a group of factors associated with increased risk for kernicterus. It was not possible to separate those infants with and without kernicterus at autopsy on the basis of the clinical factors evaluated.

<p><strong>BACKGROUND:</strong> Although, our knowledge about the factors of cardio vascular diseases (CVD) is relatively acceptable, we have few publications about the risk factors of premature CVD particularly from developing countries such as Iran.</p><p><strong>OBJECTIVES:</strong> The present study is aimed to assess the risk of the modifiable risk factors of coronary heart disease (CHD) in the first cardiac attack of patients classified by age to check which risk factors might have a more significant impact to increase the risk of premature myocardial infarction (MI).</p><p><strong>METHODS:</strong> In a case control study, 122 and 266 cases and controls were recruited from one of the main referral centres in Tehran. Cases were those who were hospitalized because of their first myocardial infarction before the ages of 50 and 55 years in males and females respectively, and compared their risk factor profiles with those experienced first MI in higher age. Main independent variables in this study were: the demographic variables, distress, lipid profile, diabetes, smoking, family history of cardio vascular diseases, and physical activity.</p><p><strong>RESULTS: </strong>The results showed that distress (OR= 3.95), minorities (compare to Fars race) (OR= 3.30), higher education (OR= 1.30), family history of hyperlipidaemia (OR=1.89) significantly increased the risk of premature MI. We also found that family history of hypertension (OR=1.35), current smoking versus no smoking (OR=1.60), fast-food consumption (OR=1.48), non-alcoholic beverages (OR= 1.12) had also association with the risk of premature MI but only in crude model. We also found that regular physical activity (OR=0.42), ex-smoker versus current smoking (OR=0.27) and regular consumption of milk (OR=0.73) was protective against premature MI.</p><p><strong>CONCLUSION:</strong> Our findings demonstrate that the effect of most of risk factors were mostly related to their life-style (distress, smoking, physical inactivity and dietary pattern); while family history of diseases was also important.</p>

Aim: To use available electronic administrative records to identify data reliability, predict discharge destination, and identify risk factors associated with specific outcomes following hospital admission with stroke, compared to stroke specific clinical factors, using machine learning techniques.Method: The study included 2,531 patients having at least one admission with a confirmed diagnosis of stroke, collected from a regional hospital in Australia within 2009–2013. Using machine learning (penalized regression with Lasso) techniques, patients having their index admission between June 2009 and July 2012 were used to derive predictive models, and patients having their index admission between July 2012 and June 2013 were used for validation. Three different stroke types [intracerebral hemorrhage (ICH), ischemic stroke, transient ischemic attack (TIA)] were considered and five different comparison outcome settings were considered. Our electronic administrative record based predictive model was compared with a predictive model composed of “baseline” clinical features, more specific for stroke, such as age, gender, smoking habits, co-morbidities (high cholesterol, hypertension, atrial fibrillation, and ischemic heart disease), types of imaging done (CT scan, MRI, etc.), and occurrence of in-hospital pneumonia. Risk factors associated with likelihood of negative outcomes were identified.Results: The data was highly reliable at predicting discharge to rehabilitation and all other outcomes vs. death for ICH (AUC 0.85 and 0.825, respectively), all discharge outcomes except home vs. rehabilitation for ischemic stroke, and discharge home vs. others and home vs. rehabilitation for TIA (AUC 0.948 and 0.873, respectively). Electronic health record data appeared to provide improved prediction of outcomes over stroke specific clinical factors from the machine learning models. Common risk factors associated with a negative impact on expected outcomes appeared clinically intuitive, and included older age groups, prior ventilatory support, urinary incontinence, need for imaging, and need for allied health input.Conclusion: Electronic administrative records from this cohort produced reliable outcome prediction and identified clinically appropriate factors negatively impacting most outcome variables following hospital admission with stroke. This presents a means of future identification of modifiable factors associated with patient discharge destination. This may potentially aid in patient selection for certain interventions and aid in better patient and clinician education regarding expected discharge outcomes.

COVID-19 infection is characterized with hyperstimulated infl ammatory response that affects lungs, cytokine storm and acute respiratory distress syndrome. Thrombotic complications are the leading reason for death in COVID-19 patients. Those of them with previous cardio-vascular diseases or risk factors – obesity, arterial hypertension, diabetes mellitus, advanced age are with higher risk for worse clinical outcome. Coagulopathy as well as thrombocytopathy and endothelial dysfunction are signifi cant pathophysiological factors for the severe clinical course of the infection. Beside anticoagulation therapy, targetеd strategies regarding thrombocytopathy and endothelial dysfunction are necessary for the treatment of patients with COVID-19 infection.

Abstract Background No studies to date have elucidated the clinical factors associated with pedicle screw pull-out during or immediately after surgery. The aim of this study was to assess the frequency of pedicle screw pull-out by comparing intraoperative scans obtained using cone-beam computed tomography (CBCT) with postoperative scans obtained using computed tomography (CT). We also sought to determine the incidence of pedicle screw pull-out and identify relevant risk factors. Methods This was a retrospective analysis of prospectively collected data for 742 pedicle screws placed in 76 consecutive patients who underwent at least triple-level posterior fixation for thoracic or lumbar spinal injury, spinal metastasis, or pyogenic spondylitis between April 2014 and July 2020. Pedicle screw pull-out distance in the axial and sagittal planes was compared between CT scans obtained 2 days postoperatively and CBCT images acquired intraoperatively. Risk factors associated with pedicle screw pull-out were investigated by multivariate logistic regression analysis. Results Pedicle screw pull-out was seen with 58 pedicle screws (7.8%) in 26 patients (34.2%). There were significant differences in age, number of fused segments, frequency of diffuse idiopathic skeletal hyperostosis (DISH), and medical history of osteoporosis for pedicle screw pull-out. Risk factors for pedicle screw pull-out were older age (odds ratio 1.07, 95% confidence interval 1.02–1.130) and a diagnosis of DISH (odds ratio 3.35, 95% confidence interval 1.12–10.00). Several cases suggest that use of connecting rods was an important factor in intraoperative pedicle screw pull-out. Conclusions Our findings suggest that age, number of fused segments, presence of DISH, and medical history of osteoporosis are risk factors for pedicle screw pull-out, with the greatest being older age and DISH.
