Abstract Background Prolonged QT intervals have been observed in pregnant women, especially those with twin pregnancy, which predisposes them to a high risk of ventricular arrhythmias. Purpose To evaluate the prevalence of acquired long QT syndrome (aLQTS) in hospitalized parturient women with single and twin pregnancy and search for potential risk factors. Methods Information about age-matched parturient women with single and twin pregnancy were retrospectively collected in our hospital from January 2016 to June 2018. The prevalence of aLQTS was evaluated. The common risk factors for corrected QT (QTc) prolongation were compiled, and multivariable logistic regression analysis was used to evaluate how each factor was related to aLQTS in such population. Results Totally 293 parturient women (147 twin pregnancy, 50.17%) were included. The prevalence of aLQTS was 72.70% in all cases, 53.15% in the single pregnancy, 93.20% in the twin pregnancy. The proportion of severely prolonged QTc was 36.18% in all cases, 8.22% in the single pregnancy and 63.95% in the twin pregnancy. The QTc interval was much longer in the twin pregnancy than in the single pregnancy with significant difference. Differences in systolic blood pressure, diastolic blood pressure, total cholesterol, serum uric acid, fetal weight, QRS, RV5+SV1, Tp-Te, Tp-Te/QT have been revealed to be statistically significant between the QTc-prolongation group and the QTc-normal group. The incidence of gestational hypertension and twin pregnancy in the QTc-prolongation group were more prevalent than in the QTc-normal group with significant difference. In the multivariable logistic regression analysis, gestational hypertension, twin pregnancy, increase of diastolic blood pressure, high total cholesterol, high serum uric acid, and heavy fetal weight were identified to be associated with QTc prolongation in parturient women. Table 1. Risk factors significantly correlated with QTc prolongation in parturient women Index P value OR (95% CI) DBP (mmHg) 0.033* 1.052 (1.004 to 1.101) TC (mmol/L) 0.001** 1.442 (1.165 to 1.785) UA (μmol/L) 0.007** 1.004 (1.001 to 1.008) Fetal weight (g) <0.001** 1.001 (1.001 to 1.001) Hypertention (%) 0.029* 2.561 (1.099 to 5.967) Twin (%) <0.001** 12.618 (6.145 to 25.909) Conclusion To our knowledge, this is the first clinical study to evaluate the prevalence of aLQTS between single and twin pregnancy. The prevalence of aLQTS is much higher in the parturient women, particularly in twin pregnancy.

Abstract Purpose: To quantitatively investigate the impact of left atrial (LA) geometric remodeling on atrial fibrillation (AF) recurrence after catheter ablation (CA).Methods: A retrospective analysis of 105 patients with AF who underwent coronary computed tomographic angiography before CA. Risk factors for AF recurrence were identified by multivariable logistic regression analysis and used to create a nomogram.Results: After at least 12 months of follow-up, 30 patients (29%) developed recurrent AF. Patients with recurrence had a higher LA volume, LA sphericity, and a lower LA ejection fraction (LAEF) (P < 0.05). There was no significant difference in asymmetry index between the two groups (P = 0.121). Multivariable regression analysis showed that LA minimal volume index (LAVImin) (OR: 1.280, 95% CI: 1.027–1.594, P = 0.028), LA sphericity (OR: 1.268, 95% CI: 1.071–1.500, P = 0.006) and CHA2DS2-VASc score (OR: 1.326, 95% CI: 1.016–1.732, P=0.038) were independent predictors of AF recurrence. The combined model of the LA sphericity to the LAVImin substantially increased the predictive power for AF recurrence (area under the curve [AUC] = 0.736, 95% CI: 0.627–0.844, P < 0.001), with a sensitivity of 80% and a specificity of 61%. A nomogram was generated based on the contribution weights of the risk factors; the AUC was 0.769 (95% CI: 0.666–0.872) and had good internal validity.Conclusion: The CHA2DS2-VASc score, LA sphericity, and LAVImin were significant and independent predictors of AF recurrence after CA. Furthermore, the nomogram had a better predictive capacity for AF recurrence.

Hemophilia usually presents as bleeding after minor trauma or as a spontaneous bleed due its hypocoagulable state. Hemophilia A represents 80-85% of the total hemophilia population with a prevalence of 1:10,000. Cardiovascular risk factors were common in the general population compared with hemophilia patients. This study aims to identify cardiovascular risk factors in adult Javanese patients with hemophilia A and their relationship with hemophilia severity. This cross-sectional study involved registered Javanese race male patients at Dr. Moewardi General Hospital from November 2019 - April 2020. There are 76 hemophilia A patients, after excluding patients with other comorbidities, non-Javanese race and age &gt;18 years old, 33 appropriate patients were then randomized. The study group consists of 30 patients with hemophilia A and 30 non-hemophilia patients. Data were collected once during patient visits to the hospital polyclinic. The collected data were body mass index (BMI), blood pressure, fasting blood sugar (FBS), total cholesterol, and uric acid. They were analyzed using the Spearman rank test. Median values of BMI scores were 20.82 (13.67-41.52) kg/m² for hemophilia A group and 24.67 (9.38-53.32) kg/m² for the control group (p &lt; 0.05). Further, median values of diastolic blood pressure, the median of FBS, and mean values of the uric acid level also showed a significant difference (p &lt; 0.05). Otherwise, the mean values of systolic blood pressure and median values of total cholesterol showed no significant difference. The BMI score, diastolic blood pressure, fasting blood sugar, and uric acid appear to be significant cardiovascular risk factor profiles in Javanese adult patients with hemophilia A. Hence, there must be a consideration, screening, and treatment for the cardiovascular risk factors in hemophilia A patients. Although the other studies are not sufficient to show recommended therapeutic targets and the results of reducing cardiovascular risk factors in hemophilia patients.

… Objective: Aim of the study was to ascertain prospectively the prognostic value of serum uric acid for fetal and maternal outcomes in women with gestational hypertension. Patients and Methods: This prospective study was conducted at department of Gynae & Obs, Maternal and Child Health Center, PIMS Islamabad, from January to December 2003. A total of 200 women with a gestational age >20 weeks, and blood pressure >130/90 mmHg were inducted in the study. At presentation serum uric acid, creatinine, hemoglobin, and platelets were measured along with blood pressure. All patients were divided into group A (uric acid <4.5 mg/dl) and group B (>4.5 mg/dl) and were followed for one month after the delivery to record pregnancy and neonatal outcome. Results: A significant difference (p<0.05) in the levels of uric acid, hemoglobin, platelet count, creatinine and blood pressure was noted between patients of group A and B. A significant decrease (p<0.05) in preterm delivery, baby birth weight and increase in fetal mortality was noted in patients of group B as compared to those of group A. Regarding maternal outcome preeclampsia (p=0.005, CI: 0.143-0.689), deranged liver functions (p=0.000, CI: 0.062-0.397), and disseminated intravascular coagulation (p=0.005; CI: 0.049-0.626) was noted in patients of group B as compared to group A. The patients of Group B showed a significant low birth weight, increased fetal mortality rate (p=0.005, CI: 0.030-0.622) and more chances of shifting neonates to NICU (p=0.002, CI: 0.164-0.667) as compared to those of group A. Conclusions: Hyperuricaemia in setting of gestational hypertension was associated with adverse fetal and maternal outcome.

Abstract. Vitamin B12 deficiency may have indirect cardiovascular effects in addition to hematological and neuropsychiatric symptoms. It was shown that the monocyte count-to-high density lipoprotein cholesterol (HDL-C) ratio (MHR) is a novel cardiovascular marker. In this study, the aim was to evaluate whether MHR was high in patients with vitamin B12 deficiency and its relationship with cardiometabolic risk factors. The study included 128 patients diagnosed with vitamin B12 deficiency and 93 healthy controls. Patients with vitamin B12 deficiency had significantly higher systolic blood pressure (SBP), diastolic blood pressure (DBP), MHR, C-reactive protein (CRP) and uric acid levels compared with the controls (median 139 vs 115 mmHg, p < 0.001; 80 vs 70 mmHg, p < 0.001; 14.2 vs 9.5, p < 0.001; 10.2 vs 4 mg/dl p < 0.001; 6.68 vs 4.8 mg/dl, p < 0.001 respectively). The prevalence of left ventricular hypertrophy was higher in vitamin B12 deficiency group (43.8%) than the control group (8.6%) (p < 0.001). In vitamin B12 deficiency group, a positive correlation was detected between MHR and SBP, CRP and uric acid (p < 0.001 r:0.34, p < 0.001 r:0.30, p < 0.001 r:0.5, respectively) and a significant negative correlation was detected between MHR and T-CHOL, LDL, HDL and B12 (p < 0.001 r: −0.39, p < 0.001 r: −0.34, p < 0.001 r: −0.57, p < 0.04 r: −0.17, respectively). MHR was high in vitamin B12 deficiency group, and correlated with the cardiometabolic risk factors in this group, which were SBP, CRP, uric acid and HDL. In conclusion, MRH, which can be easily calculated in clinical practice, can be a useful marker to assess cardiovascular risk in patients with vitamin B12 deficiency.

Background: Metabolic factors have been linked to tendinopathies, yet few studies have investigated the association between metabolic factors and lateral epicondylitis. Purpose: To evaluate risk factors for lateral epicondylitis, including several metabolic factors. Study Design: Case-control study; Level of evidence, 3. Methods: We evaluated 1 elbow in each of 937 volunteers from a rural region that employs many agricultural laborers. Each participant received a questionnaire, physical examinations, blood tests, simple radiographic evaluations of both elbows, magnetic resonance imaging of bilateral shoulders, and an electrophysiological study of bilateral upper extremities. Lateral epicondylitis was diagnosed using 3 criteria: (1) pain at the lateral aspect of the elbow, (2) point tenderness over the lateral epicondyle, and (3) pain during resistive wrist dorsiflexion with the elbow in full extension. Multivariable logistic regression analysis was used to calculate the odds ratios (ORs) and 95% CIs for various demographic, physical, and social factors, including age, sex, waist circumference, dominant-side involvement, smoking habit, alcohol intake, and participation in manual labor; the comorbidities of diabetes, hypertension, thyroid dysfunction, metabolic syndrome, ipsilateral biceps tendon injury, ipsilateral rotator cuff tear, and ipsilateral carpal tunnel syndrome; and the serologic parameters of serum lipid profile, glycosylated hemoglobin A1c, level of thyroid hormone, and high-sensitivity C-reactive protein. Results: The prevalence of lateral epicondylitis was 26.1% (245/937 participants). According to the multivariable logistic regression analysis, female sex (OR, 2.47; 95% CI, 1.78-3.43), dominant-side involvement (OR, 3.21; 95% CI, 2.24-4.60), manual labor (OR, 2.25; 95% CI, 1.48-3.43), and ipsilateral rotator cuff tear (OR, 2.77; 95% CI, 1.96-3.91) were significantly associated with lateral epicondylitis ( P < .001 for all). No metabolic factors were significantly associated with lateral epicondylitis. Conclusion: Female sex, dominant-side involvement, manual labor, and ipsilateral rotator cuff tear were found to be risk factors for lateral epicondylitis. The study results suggest that overuse activity is more strongly associated with lateral epicondylitis than are metabolic factors.

Objectives: Prehypertension frequently progresses to hypertension and is associated with cardiovascular diseases, stroke, excess morbidity and mortality. However, the identical risk factors for developing hypertension from prehypertension are not clarified. This study is conducted to clarify the risks. Methods: We conducted a retrospective 5-year cohort study using the data from 3,584 prehypertensive Japanese adults (52.1±11.0 years, 2,081 men) in 2004 and reevaluated it 5 years later. We calculated the cumulative incidences of hypertension over 5 years, then, we detected the risk factors and calculated odds ratios (ORs) for developing hypertension by crude analysis and after adjustments for age, sex, body mass index, smoking and drinking habits, baseline systolic and diastolic blood pressure, pulse rate, diabetes mellitus, dyslipidemia, chronic kidney disease, and serum uric acid. We also evaluated whether serum uric acid (hyperuricemia) provided an independent risk for developing hypertension. Results: The cumulative incidence of hypertension from prehypertension over 5 years was 25.3%, but there were no significant differences between women and men (24.4% vs 26.0%, p=0.28). The cumulative incidence of hypertension in subjects with hyperuricemia (n=726) was significantly higher than those without hyperuricemia (n=2,858) (30.7% vs 24.0%, p<0.001). After multivariable adjustments, the risk factors for developing hypertension from prehypertension were age (OR per 1 year increased: 1.023; 95% CI, 1.015-1.032), women (OR versus men: 1.595; 95% CI, 1.269-2.005), higher body mass index (OR per 1 kg/m 2 increased: 1.051; 95% CI 1.021-1.081), higher baseline systolic blood pressure (OR per 1 mmHg increased: 1.072; 95% CI, 1.055-1.089) and diastolic blood pressure (OR per 1 mmHg increased: 1.085; 95% CI, 1.065-1.106), and higher serum uric acid (OR pre 1 mg/dL increased: 1.149; 95% CI, 1.066-1.238), but not smoking and drinking habits, diabetes mellitus, dyslipidemia, and chronic kidney diseases. Conclusions: Increased serum uric acid is an independent risk factor for developing hypertension from prehypertension. Intervention studies are needed to clarify whether the treatments for hyperuricemia in prehypertensive subjects are useful.

OBJECTIVEIn this analysis the authors compare the characteristics of smokers to nonsmokers using demographic, socioeconomic, and comorbidity variables. They also investigate which of these characteristics are most strongly associated with smoking status. Finally, the authors investigate whether the association between known patient risk factors and disability outcome is differentially modified by patient smoking status for those who have undergone surgery for lumbar degeneration.METHODSA total of 7547 patients undergoing degenerative lumbar surgery were entered into a prospective multicenter registry (Quality Outcomes Database [QOD]). A retrospective analysis of the prospectively collected data was conducted. Patients were dichotomized as smokers (current smokers) and nonsmokers. Multivariable logistic regression analysis fitted for patient smoking status and subsequent measurement of variable importance was performed to identify the strongest patient characteristics associated with smoking status. Multivariable linear regression models fitted for 12-month Oswestry Disability Index (ODI) scores in subsets of smokers and nonsmokers was performed to investigate whether differential effects of risk factors by smoking status might be present.RESULTSIn total, 18% (n = 1365) of patients were smokers and 82% (n = 6182) were nonsmokers. In a multivariable logistic regression analysis, the factors significantly associated with patients’ smoking status were sex (p < 0.0001), age (p < 0.0001), body mass index (p < 0.0001), educational status (p < 0.0001), insurance status (p < 0.001), and employment/occupation (p = 0.0024). Patients with diabetes had lowers odds of being a smoker (p = 0.0008), while patients with coronary artery disease had greater odds of being a smoker (p = 0.044). Patients’ propensity for smoking was also significantly associated with higher American Society of Anesthesiologists (ASA) class (p < 0.0001), anterior-alone surgical approach (p = 0.018), greater number of levels (p = 0.0246), decompression only (p = 0.0001), and higher baseline ODI score (p < 0.0001). In a multivariable proportional odds logistic regression model, the adjusted odds ratio of risk factors and direction of improvement in 12-month ODI scores remained similar between the subsets of smokers and nonsmokers.CONCLUSIONSUsing a large, national, multiinstitutional registry, the authors described the profile of patients who undergo lumbar spine surgery and its association with their smoking status. Compared with nonsmokers, smokers were younger, male, nondiabetic, nonobese patients presenting with leg pain more so than back pain, with higher ASA classes, higher disability, less education, more likely to be unemployed, and with Medicaid/uninsured insurance status. Smoking status did not affect the association between these risk factors and 12-month ODI outcome, suggesting that interventions for modifiable risk factors are equally efficacious between smokers and nonsmokers.

Acute Kidney Injury Development

Introduction. Acute kidney injury associated with cardiac surgery is a common and significant postoperative complication. With a frequency of 9 - 39% according to different studies, it is the second most common cause of acute kidney injury in intensive care units, and an independent predictor of mortality. This study aimed to investigate the importance of preoperative hemoglobin and uric acid levels as risk factors for acute kidney injury in the postoperative period in cardiac surgery patients. Material and Methods. The study included a total of 118 patients who were divided into two groups. Each group included 59 patients; the fist group included patients who developed acute kidney injury and required renal replacement therapy, and the second included patients without acute kidney injury. Types of cardiac surgery included coronary, valvular, combined, aortic dissection, and others. All necessary data were collected from patient medical records and the electronic database. Results. A statistically significant difference was found between the groups in preoperative hemoglobin levels (108.0 vs. 143.0 g/l, p = 0.0005); postoperative urea (26.4 vs. 5.8 mmol/l, p = 0.0005) and creatinine (371.0 vs. 95.0 ?mol/l, p = 0.0005), acute phase inflammatory reactants C-reactive protein (119.4 vs. 78.9 mg/l, p = 0.002) and procalcitonin (7.0 vs. 0.2 ng/ml, p = 0.0005), creatine kinase myocardial band isoenzyme (1045.0 vs. 647.0 mg/l, p = 0.014); duration of extracorporeal circulation (103.5 vs. 76.0 min, p = 0.0005) and ascending aortic clamp during cardiac surgery (89.0 vs. 67.0 min, p = 0.0005). The exception was the preoperative uric acid level, where there was no statistically significant difference (382.0 vs. 364.0 ?mol/l, p = 0.068). There was a statistically significant correlation between the use of inotropic agents and acute kidney injury development. Conclusion. There is a correlation between the preoperative low hemoglobin levels and postoperative acute kidney injury. There is no statistically significant correlation between the preoperative levels of uric acid and postoperative acute kidney injury.

A cross-sectional study was carried out from November 2015 to march 2016 on bovine fasciolosis, to assess the abattoir based prevalence, predominant species of bovine fasciolosis and associated risk factors of the disease in cattle slaughtered in Halaba municipal abattoir. A total of 384 cattle were examined using post mortem examination. Infection rates were (3.64%), 2.34%, 2.08%, and 1.82 % F. gigantic, F. hepatica, mixed and immature respectively with the overall prevalence of 9.88 % (38). F. gigantic was found to be the most prevalent species in cattle of the study area. Multivariable logistic regression analysis showed that the risk of fasciola infection was significantly higher in poor body condition animals than in medium and good body condition animals (p < 0.05). However, in terms of age, sex and breed, no statistically significant difference was found between infected animals (p > 0.05).The present study showed that bovine fasciolosis is one of the important pathogens in cattle in the study area and warrants appropriate disease prevention and control measures and further epidemiological investigations to determine the different agro ecological risk factors on the occurrence of the disease.

Atherosclerotic Risk Factors

Correlations between aerobic capacity, obesity, and atherosclerotic risk factors were evaluated in adolescents with low-to-moderate levels of physical fitness. Subjects with higher levels of fitness had a more favorable risk profile with decreased body mass index, lower systolic and diastolic blood pressure and plasma triglyceride levels, and higher plasma high-density lipoprotein-cholesterol levels. Simple linear regression analysis revealed an association between body mass index and blood pressure, plasma triglyceride and plasma highdensity lipoprotein-cholesterol. The level of aerobic fitness as determined by exercise duration was also associated with the same atherosclerotic risk factors. However, multiple linear regression analysis demonstrated that body mass index provided the largest explanation, by those variables examined, of the interindividual variance in blood pressure, plasma triglyceride, and high-density lipoprotein-cholesterol. Aerobic fitness contributed only minimally to the variation in these risk factors. These findings suggest that if aerobic conditioning is used to modify atherosclerotic risk factors, it should be accompanied by a reduction in weight in adolescents with low-to-moderate levels of physical fitness.
