Infection Risk Factors

Background Infectious peritonitis is a clinically important condition contributing to the significant mortality and morbidity rates observed in peritoneal dialysis (PD) patients. Although some of the socioeconomic risk factors for PD-associated peritonitis have been identified, it is still unclear why certain patients are more susceptible than others to infection. Methods We examined the molecular components of human peritoneal dialysate (HPD) in an attempt to identify factors that might increase patient susceptibility to infection. Characterization studies were performed on initial and follow-up dialysate samples collected from 9 renal failure patients on PD. Results Our in vitro data showed that peritonitis-causing bacteria grew differently in the patient dialysates. Proteomic analysis identified an association between transferrin presence and infection risk, as peritoneal transferrin was discovered to be iron-saturated, which was in marked contrast to transferrin in blood. Further, use of radioactive iron-labeled transferrin showed peritoneal transferrin could act as a direct iron source for the growth of peritonitis-causing bacteria. We also found catecholamine stress hormones noradrenaline and adrenaline were present in the dialysates and were apparently involved in enhancing the growth of the bacteria via transferrin iron provision. This suggests the iron biology status of the PD patient may be a risk factor for development of infectious peritonitis Conclusions Collectively, our study suggests transferrin and catecholamines within peritoneal dialysate may be indicators of the potential for bacterial growth in HPD and, as infection risk factors, represent possible future targets for therapeutic manipulation.

Pulmonary vascular disease is a risk factor for the surgical management of common arterial trunk. Surgical repair, therefore, is usually performed in early infancy, before irreversible changes can occur in the epulmonary vasculature. Because of this, there has been an increasing tendency to dispense with cardiac catheterisation as a means of assessing pulmonary vascular disease. Cardiac catheterisation, nonetheless, is still performed when there is a risk of pulmonary vascular disease, such as in older children. There are no clear guidelines, however, as to who should be catheterised. We have developed a simple screening test to help make this decision.

Introduction: The AHA notes that more than 76% of strokes are the first occurrence. There are class 1 recommendations for the management of common risk factors such as atrial fibrillation (AF), hyperlipidemia (HLD), hypertension (HTN), diabetes (DM), and vascular disease. The purpose of this study is to investigate the percentage of large vessel strokes that are potentially preventable with adequate management of vascular risk factors. Methods: A retrospective chart review was conducted on all patients undergoing endovascular therapy (EVT) from 2012-2019. Data was collected on vascular risk factors present prior to admission including HTN, DM, HLD, AF, and smoking. Preventable stroke was defined as having at least one of the following: untreated AF, untreated HLD, poorly controlled HTN (presence of left ventricular hypertrophy on transthoracic echo), history of vascular disease not on an antiplatelet agent, poorly controlled DM (A1c>10), current smoking. Groups were compared based on age, sex and 90 day functional outcomes, with favorable outcome defined as mRS ≤ 2. Results: Our sample included 396 patients who underwent EVT (mean age 65, 50% female). 42% of patients with Afib were not on anticoagulation, 31% of patients with HLD were untreated, 39% of patients with HTN were poorly controlled, 27% of patients with a history of vascular disease were not on an antiplatelet, 14% of patients with DM were poorly controlled, and 46% of all patients were smokers. In total, 78% of patients had at least 1 poorly controlled risk factor and 37% had at least 2. There was no difference in rates of preventable stroke between males and females (48% vs 52%, p=0.30) and between age groups above and below 70 (40% vs 60%, p=0.68). 64% of patients with well controlled risk factors had a favorable outcome compared to 51% with at least one poorly controlled risk factor (p=0.03). Conclusions: Our data suggests that despite guidelines on management of vascular risk factors, a large number of these are poorly controlled prior to admission for large vessel stroke, leading to a potentially preventable procedure. Not only could improved primary prevention save the wide array of resources utilized in EVT, but it could also influence long term outcomes in this cohort of patients.

Introduction: Aneurysms and dissections at the thoracic aorta (TAA) are the leading causes of mortality and morbidity in the United States and Japan. Although hypertension is a major risk for TAA, several studies have indicated that genetic factors also influence the structural formation of TAA. The purpose of the present study was to identify gene polymorphisms associated with TAA among hypertensive patients for assessment of the genetic risk for this condition. Methods: This case-control study comprised 1351 hypertensive individuals, including 88 subjects with TAA and 1263 without any cardiovascular complications. The genotypes for 142 polymorphisms of 121 candidate genes were determined by a method that combines the polymerase chain reaction and sequence-specific oligonucleotide probes with suspension array technology. Results: Evaluation of genotype distributions by the chi-square test and subsequent multivariable logistic regression analysis with adjustment for age, sex, body mass index, and prevalence of smoking, diabetes mellitus, hypercholesterolemia, and metabolic syndrome revealed that the T→G (3′ UTR) polymorphism of the thrombospondin 2 gene ( THBS2 ; odds ratio, 4.7) is significantly (P < 0.05) associated with TAA in hypertensive subjects, with the variant G allele representing a risk factor for this condition. Furthermore, the -110A→C polymorphism of heat-shock 70-kD protein 8 gene ( HSPA8 ; odd ratio, 0.3), the C→T (Pro198Leu) polymorphism of the glutathione peroxidase gene ( GPX1 ; odds ratio, 0.3), the -6G→A polymorphism of angiotensin 1 gene ( AGT ; odds ratio, 0.3), and the -850C→T polymorphism of tumor necrosis factor gene ( TNF ; odds ratio, 0.5) were significantly associated with this condition, with the variant allele of each polymorphism being protective against this condition. A stepwise forward selection procedure revealed that polymorphisms of THBS2 , HSPA8 , GPX1 , AGT , and TNF significantly affected the prevalence of TAA. Conclusions: Genetic variant of THBS2 may be a risk factor for TAA in hypertensive patients, whereas variants of HSPA8 , GPX1 , AGT , and TNF may be protective against this condition. Determination of genotypes for these polymorphisms may prove informative for assessment of the genetic risk for TAA.

Background: Coronary artery diseases are one of the major challenges faced by cardiologists. Control of certain risk factors for CAD is associated with decrease in mortality and morbidity from myocardial infarction and unstable angina. So, identification and taking appropriate measures for primary and secondary prevention of such risk factors is, therefore, of great importance. This retrospective study was carried at the newly set up cath lab in Dhaka Medical college. Materials and Methods: Total 228 consecutive case undergone diagnostic coronary angiogram from 10th January 2007 to31st January 2009 out of which 194(80%) were male and 34 (20%) were female. In both sexes most of the patients were between 41 to 60 years of age. Risk factors of the patients were evaluated. Results: In females commonest risk factor was Diabetes (58.8%) followed by dyslipidaemia (35.3%). In males commonest risk factor was hypertension (30.9%) followed by smoking (29.9%) and diabetes (28.3%). In males 44.3% patients presented with acute myocardial infarction followed by stable angina (43.3%); but in females stable angina was the commonest presentation (50.0%) followed by myocardial infarction (38.2%).CAG findings revealed that in males 33.5% had double vessel disease 26.8% followed by single vessel 26.8% and multivessel disease 25.3%. In females normal CAG was found in 35.5% followed by double vessel 23.5%, multivessel 20.6% and single vessel 20.6%. On the basis of CAG findings; in males 41.8% patients were recommended for CABG, followed by PTCA & stenting 26.3% and medical therapy 30.0%; where as in females 55.9% were recommended for medical therapy , followed by CABG 32.4% and PTCA & stenting11.8%. Conclusion: The commonest presentation of CAD was 4th and 5th decades in both sexes. Diabetes and dyslipidaemia were more common in females whereas hypertension and smoking were more common in males. Myocardial infarction and stable angina were most common presentation in both sexes though in males myocardial infarction was more common. In males the angiographic severity of CAD was more and they were more subjected for CABG in comparison to females. Key words: Risk factors; Coronary angiography.

Pyomyoma, or suppurative leiomyoma, is a rare but serious complication of uterine fibroids. The mechanism of pyomyoma is an infection caused by microorganisms coming from ascending or hematogenously on the ground of necrosis following ischemia and infarction. It can be seen during the course of pregnancy or after abortion and birth. It can also develop after uterine instrumentation or due to cervical stenosis. Patients often present with pain and fever. It should be considered in cases had no other etiology of fever and had a history of uterine fibroids. Diagnosis and treatment are often delayed due to non-specific presentation and imaging findings. This delay increases the risk of mortality and morbidity such as fertility loss. In the vast majority of these cases, total abdominal hysterectomy is required. The case we presented is a premenopausal and sexually inactive woman without any history of pregnancy or uterine instrumentation or immunocompromised. This patient is the 5th case of pyomyoma without risk factor and the 3rd case that was successfully treated with myomectomy. Knowing the proper treatment of pyomyoma will be beneficial to prevent potential mortality and morbidity.

Abstract Purpose Extracorporeal membrane oxygenation (ECMO) is the primary indication for transplanted right heart failure in transition and postoperative period for heart transplantation patients. This study explored risk factors affecting the clinical prognosis of ECMO through analyzing the clinical data of heart transplantation patients with such condition. Methods Data on 28 heart transplantation patients with ECMO obtained from January 2012 to January 2018 in the People’s Hospital of Zhongshan City were retrospectively analyzed. Results A total of 25 patients (20 male and 5 female) were included in this study. Heart transplantation among patients was performed mainly due to cardiomyopathy (77.8%). Eighteen patients survived and were discharged 18 (72%). Four patients were treated with cardiopulmonary resuscitation before ECMO, and three patients died in the hospital. No differences existed among the surviving and death group donors (N-terminal pro b-type natriuretic peptide（NT-proBNP）, creatine kinase-muscle/brain（CK-MB）, warm ischemia time of donated heart, cold ischemia time of donated heart, total ischemia time of donated heart, and donator type). Univariate analysis showed that body mass index(BMI), length of stay in intensive care unit(ICU), and cardiopulmonary resuscitation are relevant prognosis factors in applying ECMO for patients with heart transplantation. Multi-factor logistic regression results show that cardiopulmonary resuscitation before ECMO (OR: 49.45, 95% CI[1.37, 1781.6]; P=0.033) is an independent risk factor influencing prognosis. Conclusion ECMO is an important life support method for patients with heart transplantation before and after the operation. Patients with obesity, poor preoperative cardiac function, and considerable red blood cell transfusions during surgery may influence the prognosis of patients. Extracardiac compression before ECMO of patients is an independent risk factor for their prognosis.
