The role of miR-433-3p in vascular calcification in type 2 diabetic patients: targeting WNT/ß-Catenin and RANKL/RANK/OPG signaling pathways.

BACKGROUND: Vascular calcification (VC) is a major predictor of cardiovascular diseases that represent the principal cause of mortality among type-2 diabetic patients. Accumulating data suggest the vital role of some microRNAs on vascular calcification as an epigenetic regulator. Thus, we assessed herein, the role of serum miR-433-3p in vascular calcification in type-2 diabetic patients. METHODS: Twenty healthy subjects (control group) and forty diabetic patients (20 without VC and 20 with VC) were involved in the study. miR-433-3p gene expression was measured. Runx2, Dickkopf-1 (DKK1), ß-catenin, Receptor activator of nuclear factor kappa-B ligand (RANKL), and osteoprotegerin (OPG) levels in serum were assessed by ELISA technique. RESULTS: Diabetes patients had significantly lower levels of miR-433-3p expression in comparison to the control group, with the lowest levels being found in diabetic patients with VC. Furthermore, Runx2, ß-catenin, and RANKL levels were significantly increased with concomitant lower DKK1 and OPG levels detected in the two diabetic groups especially those with VC. CONCLUSION: Collectively, the study documented that down-regulation of miR-433-3p may contribute to the development of VC through activating WNT/ß-Catenin and RANKL/RANK/OPG signaling pathways.

Prevalence, Predictors, and Outcomes of Resistant Hypertension in Egyptian Population.

Background: Hypertension is a leading problem; it affects around thirty million adult Egyptians, according to the last national registry. The exact prevalence of resistant hypertension (RH) in Egypt wasn't spotted before. The purpose of this study was to determine the prevalence, predictors, and impact on adverse cardiovascular outcomes among adult Egyptians with RH. Methods: The present study examined a cohort of 990 hypertensive patients who were divided into two groups based on their blood pressure control; group I (n = 842) patients who achieved blood pressure control and group II (n = 148) patients who met the RH definition criteria. All patients underwent a close follow-up for one year to evaluate the major cardiovascular events. Results: The prevalence of RH was 14.9%. The main predictors impacting the cardiovascular outcomes of RH were advanced age (≥65 years), the presence of chronic kidney diseases, a BMI ≥ 30 kg/m2, and NSAID use. After one year of follow-up, the RH group displayed noticeably higher rates of major cardiovascular events, including new-onset atrial fibrillation (6.8% vs. 2.5%, P = 0.006), cerebral stroke (4.1% vs. 1.2%, P = 0.011), myocardial infarction (4.7% vs. 1.3%, P = 0.004), and acute heart failure (4.7% vs. 1.8%, P = 0.025). Conclusion: The prevalence of RH in Egypt is moderately high. Patients with RH have a far higher risk of cardiovascular events than those whose blood pressure is within control.

The Value of Intermittent Fasting and Low Carbohydrate Diet in Prediabetic Patients for the Prevention of Cardiovascular Diseases. / Papel do Jejum Intermitente e da Dieta Restrita em Carboidratos na Prevenção de Doenças Cardiovasculares em Pacientes Pré-Diabéticos.

BACKGROUND: Prediabetic patients are at increased risk for cardiovascular diseases and the development of microvascular and macrovascular complications. Intermittent fasting (IF) and low-carbohydrate diet (LCD) are promising dietary plans. OBJECTIVES: Our aims to analyze the benefits of IF combined with LCD on microvascular and macrovascular outcomes in prediabetic patients. METHODS: The study included 485 prediabetic patients with no history of cardiovascular diseases divided into group I: (n = 240 patients) who underwent IF (16 h IF 3-4 days per week) combined with LCD (<130 g of carbohydrate per day), and group II: (n = 245 patients) with ad libitum calorie intake. The two groups were followed-up for two years for assessment of micro and macrovascular complications. A p-value < 0.05 was considered statistically significant. RESULT: There was a significant reduction in body weight, body mass index, waist circumference, body fat percentage and glycated hemoglobin in group I. The incidence of progression from prediabetes to diabetes was significantly lower in group I (2.1% vs. 6.9% in group II, p = 0.010). In addition, a significant increase in the incidence of microvascular and macrovascular complications was observed in group II, including retinopathy, neuropathy and unstable angina. Multivariate regression analysis revealed that increased body weight, fasting glucose, glycated hemoglobin and low-density lipoprotein were independent risk factors impacting microvascular and macrovascular outcomes. CONCLUSIONS: In prediabetic patients, IF, combined with LCD, was associated with lower progression to diabetes mellitus and lower incidence of microvascular and macrovascular complications.

FUNDAMENTOS: Pacientes pré-diabéticos têm alto risco de doenças cardiovasculares e complicações microvasculares e macrovasculares. O Jejum Intermitente (JI) e a dieta restrita em carboidratos (dieta low-carb, DLC) são estratégias dietéticas promissoras nesse grupo. OBJETIVOS: Analisar os benefícios da combinação do JI com DLC sobre desfechos microvasculares e macrovasculares em pacientes pré-diabéticos. MÉTODOS: O estudo incluiu 485 pacientes pré-diabéticos sem história de doença cardiovascular. Os pacientes foram divididos em dois grupos: grupo I (n = 240) submetidos ao JI (16 horas de JI, F 3-4 dias por semana) combinado com DLC (<130 g de carboidratos por dia), e grupo II (n = 245) que consumiram alimentos à vontade (grupo controle). Os dois grupos foram acompanhados por dois anos para avaliação de complicações macrovasculares e microvasculares. Um valor p < 0,05 foi considerado estatisticamente significativo. RESULTADOS: Houve uma redução significativa no peso corporal, índice de massa corporal, porcentagem de gordura corporal e hemoglobina glicada no grupo I. A incidência de progressão de pré-diabetes para diabetes foi significativamente menor no grupo I (2,1%) que no grupo II (6,9%) (p = 0,010). Ainda, um aumento significativo na incidência de complicações microvasculares e macrovasculares foi observado no grupo II, incluindo retinopatia, neuropatia e angina instável. A análise de regressão multivariada revelou que peso corporal aumentado, e níveis elevados de glicemia de jejum, hemoglobina glicada e lipoproteína de baixa densidade foram fatores de risco independentes de desfechos microvasculares e macrovasculares. CONCLUSÕES: Em pacientes pré-diabéticos, o JI, combinado com DLC, associou-se com menor progressão para diabetes mellitus e menor incidência de complicações microvasculares e macrovasculares.

Impact of Patient Unawareness and Socioeconomic Factors on Patient Presentation to Primary Percutaneous Coronary Intervention. / Impacto do Desconhecimento do Paciente e Fatores Socioeconômicos na Apresentação do Paciente à Intervenção Coronária Percutânea Primária.

BACKGROUND: Patient unawareness about acute myocardial infarction, its complications and the benefits of early revascularization is a crucial point that determines the outcomes. Moreover, the relationship between socioeconomic factors and patient presentation to primary percutaneous coronary intervention (PPCI) has not been fully studied. OBJECTIVES: Our objective was to investigate whether or not patient unawareness and other socioeconomic factors impact patient presentation to PPCI. METHODS: The study comprised 570 patients with ST-segment elevation myocardial infarction (STEMI) revascularized by PPCI. The patients were classified into two groups according to the total ischemia time (the time from STEMI symptom onset to balloon dilatation); group I: Patients with early presentation (1-12 hours). Group II: Patients with late presentation (>12-24 hours). Socioeconomic factors, clinical outcomes including mortality and major adverse cardiac events (MACE) were evaluated in each group. A p-value < 0.05 was considered statistically significant. RESULTS: There are different socioeconomic factors affecting patient presentation to PPCI. Multivariate regression analysis identified the independent socioeconomic predictors as following: low educational level - OR 4.357 (CI95% 1.087-17.47, p=0.038), social isolation - OR 4.390 (CI95% 1.158-16.64, p=0.030) and unawareness about the benefits of early revascularization - OR 4.396 (CI95% 1.652-11.69, p=0.003). Mortality and MACE were higher in group II. CONCLUSION: Patient unawareness and low socioeconomic status were associated with late presentation to PPCI with more adverse outcomes.

FUNDAMENTO: O desconhecimento do paciente sobre o infarto agudo do miocárdio, suas complicações e os benefícios da revascularização precoce é um ponto crucial na determinação dos desfechos. Além disso, a relação entre fatores socioeconômicos e apresentação do paciente à intervenção coronária percutânea primária (ICPP) não foi totalmente estudada. OBJETIVOS: Nosso objetivo foi investigar se o desconhecimento do paciente e outros fatores socioeconômicos impactam na apresentação do paciente à ICPP. MÉTODOS: O estudo compreendeu 570 pacientes com infarto agudo do miocárdio com supradesnivelamento do segmento ST (IAMCSST) revascularizados por ICPP. Os pacientes foram classificados em dois grupos de acordo com o tempo total de isquemia (tempo desde o início dos sintomas do IAMCSST até a dilatação com balão); grupo I: Pacientes com apresentação precoce (1-12 horas). Grupo II: Pacientes com apresentação tardia (>12-24 horas). Fatores socioeconômicos, desfechos clínicos incluindo mortalidade e eventos cardíacos adversos maiores (ECAM) foram avaliados em cada grupo. O valor de p < 0,05 foi considerado estatisticamente significante. RESULTADOS: Existem diferentes fatores socioeconômicos que afetam a apresentação do paciente à ICPP. A análise de regressão multivariada identificou os preditores socioeconômicos independentes da seguinte forma: baixa escolaridade - OR 4,357 (IC95% 1,087­17,47, p=0,038), isolamento social - OR 4,390 (IC95% 1,158­16,64, p=0,030) e desconhecimento sobre os benefícios da revascularização precoce - OR 4,396 (IC95% 1,652­11,69, p =0,003). A mortalidade e ECAM foram mais altas no grupo II. CONCLUSÃO: O desconhecimento do paciente e o baixo nível socioeconômico foram associados à apresentação tardia para a ICPP, com desfechos mais adversos.

Impact of Stress Hyperglycemia on No-Reflow Phenomenon in Patients with ST Elevation Myocardial Infarction Undergoing Primary Percutaneous Coronary Intervention.

Background: Stress hyperglycemia is a common finding during acute myocardial infarction and associated with poor prognosis. To reduce the occurrence of no-reflow, prognostic factors must be identified before primary percutaneous coronary intervention (PPCI). Our objective was to investigate the impact of stress hyperglycemia in non-diabetic and diabetic patients on no-reflow phenomenon after PPCI. Methods: The study comprised 480 patients with ST elevation myocardial infarction (STEMI) who were managed by PPCI. Patients were classified into two groups according to thrombolysis in myocardial infarction (TIMI) flow grade: Group I (Patients with normal flow, TIMI 3 flow) and Group II (Patients with no-reflow, TIMI 0-2 flow). Patients were analyzed for clinical outcomes including mortality and major adverse cardiac events. Results: Incidence of stress hyperglycemia was 14.8% in non-diabetic patients and 22.2% in diabetic patients; the incidence of no-reflow phenomenon was 13.5% and no-reflow was significantly higher in patients with stress hyperglycemia. Multivariate regression analysis identified the independent predictors of no-reflow phenomenon: stress hyperglycemia OR 3.247 (CI95% 1.656-6.368, P = 0.001), Killip class >1 OR 1.893 (CI95% 1.004-3.570, P = 0.049) and cardiogenic shock OR 3.778 (CI95% 1.458-9.790, P = 0.006). Conclusion: Stress hyperglycemia was associated with higher incidence of no-reflow phenomenon. The independent predictors of no-reflow were stress hyperglycemia, Killip class >1 and cardiogenic shock.

Impact of the Total Ischemia Time on No-Reflow Phenomenon in Patients with ST Elevation Myocardial Infarction Undergoing Primary Percutaneous Coronary Intervention.

BACKGROUND: No-reflow phenomenon after primary percutaneous coronary intervention is a common condition affecting the outcomes; therefore, studying its predictive factors is helpful in identifying patients at high risk. Our objective was to investigate the impact of the total ischemia time on no-reflow phenomenon and its correlation to thrombolysis in myocardial infarction flow grade after primary percutaneous coronary intervention. METHODS: This study was conducted on 545 patients with ST-elevation myocardial infarc-tion who underwent PPCI; the patients were divided into two groups according to the incidence of no-reflow, TIMI flow ≤2 was considered no-reflow. The time interval from chest pain onset to balloon dilatation was assessed and correlated to thrombolysis in myocardial infarction flow grade. RESULTS: The incidence of no-reflow was 13.9%; thrombolysis in myocardial infarction flow≤2 occurred in 76 patients. Multivariate regression analysis showed that advanced age>65 years, the total ischemia time >6 h, high thrombus burden, and cardiogenic shock were the independent predictors of no-reflow phenomenon. Spearman's correlation analysis showed a significant negative correlation between the total ischemia time and thrombolysis in myocardial infarction flow grade (r = -351 and P-value = .001). CONCLUSION: The time delay is the main limitation of achieving thrombolysis in myocardial infarction 3 flow after primary percutaneous coronary intervention. The total ischemia time has a significant negative correlation with thrombolysis in myocardial infarction flow grade after primary percutaneous coronary intervention.

Incidence, Predictors and Outcomes of Contrast Induced Nephropathy in Patients with ST Elevation Myocardial Infarction Undergoing Primary Percutaneous Coronary Intervention.

Background: Contrast induced nephropathy (CIN) is considered one of the most common causes of hospital acquired renal failure and severely affects morbidity and mortality. Our objective was to investigate incidence, predictors and outcomes of CIN in patients with ST elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PPCI). Methods: The study was conducted on 550 patients with STEMI subjected to PPCI. Patients were classified into two groups according to the occurrence of CIN; group I (Patients without CIN) and group II (Patients with CIN). The two groups were assessed for the clinical outcomes including mortality and major adverse cardiac events (MACE). Results: Incidence of CIN was 10.6%, multivariate regression analysis identified the independent predictors of CIN including; age > 60 years OR 6.083 (CI95% 3.143-11.77, P = 0.001), presence of diabetes mellitus OR 2.491 (CI95% 1.327-4.675, P = 0.005), non-steroidal anti-inflammatory drugs (NSAIDs) use OR 2.708 (CI95% 1.393-5.263, P = 0.003), the volume of contrast agent >200 ml OR 6.543 (CI95% 3.382-12.65, P = 0.001) and cardiogenic shock OR 4.514 (CI95% 1.738-11.72, P = 0.002). Mortality was higher in group II than group I (11.9% vs. 4.4% respectively, P = 0.015). The incidence of MACE were higher in group II than group I (heart failure; 18.6% vs. 7.3%, cardiac arrest; 8.5% vs. 2.8% and cardiogenic shock; 16.9% vs. 6.9% with P. value = 0.003, 0.024, 0.007 respectively). Conclusion: Contrast induced nephropathy was associated with increased morbidity and mortality. The independent predictors of CIN were advanced age, diabetes mellitus, NSAIDs use, the volume of contrast agent >200 ml and cardiogenic shock.

[Digestive stomas: which professional impact?] / Les stomies digestives: quel impact professionnel?

INTRODUCTION: digestive stomas result from a certain number of surgical interventions. They may be temporary or definitive. The patient with stoma has potentially damaging physical and psychological problems. Therefore patient´s adaptation to the changes and acceptance of this temporary or permanent situation is essential. This study aims to assess the impact of intestinal stomas on patients´ quality of life and professional life. METHODS: we conducted a retrospective study from January 2010 to December 2014. During the study period, 115 patients had intestinal stomas. Among these patients, sixty were of working age, had a fixed employment and had resumed their work; they made up the study population. Data were collected using a specific questionnaire: the Short Form-36 (SF-36) health questionnaire conducted in the post-operative period. RESULTS: the average score for the overall quality of life for patients with stoma was 41. Forty patients had poor quality of life with a score SF-36 less than 50. Our study showed that patients with stoma experienced difficulties at work. Forty-eight patients reported discomfort directly linked to stoma during their professional activities. The causes mentioned were physical in 6 cases and psychological in 3 cases. Six patients were moved into more adapted working positions. CONCLUSION: the management of patients with digestive stomas should aim to an adequate social and professional reintegration. This can only be done by involving the occupational physician, the psychologist, the stoma therapist and the associations.

Hepatocellular carcinoma arising from hepatic adenoma in a young woman.

Hepatocellular carcinoma (HCC) arising from hepatic adenoma is an infrequent situation. Only a few cases were reported in the literature. We present a rare case of hepatocellular carcinoma arising from HA in a young woman with no medication history of oral contraceptives. Surgical resection is the only available treatment.

Very Early Versus Early Percutaneous Coronary Intervention in Patients with Decreased e-GFR after Successful Fibrinolytic Therapy.

Background: Pharmacoinvasive strategy (PIS) is the alternative approach to primary percutaneous coronary intervention (PCI) if PCI capable center isn't available especially in the developing countries. Our objective of the current study was to investigate the incidence of contrast induced nephropathy (CIN), the occurrence of no reflow phenomenon and major adverse cardiac events (MACE) in patients with decreased estimated glomerular filtration rate (e-GFR) after successful fibrinolytic therapy in order to assess the benefit from very early PCI strategy (within 3-12 hours) or early PCI strategy (within 12-24 hours). Methods: This randomized clinical trial included 420 patients with STEMI. All participants were classified randomly into two groups according to the time of intervention; Group I patients were subjected to very early PCI (within 3-12 hours) and Group II patients were subjected to early PCI (within 12-24 hours) after receiving successful fibrinolytic therapy. Results: The incidence of CIN in Group I was slightly higher than Group II (23 patients [10.7%] versus 19 patients [9.3%]) respectively, with no statistically significant difference between the two groups (P value = 0.625). The incidence of no-reflow phenomenon (TIMI 0-2 flow) after the procedure was higher in Group II, while TIMI 3 flow (normal flow) was significantly higher in Group I than Group II (184 [85.6%] vs. 153 [74.6%], respectively) with P value = 0.044. There was no statistically significant difference between the two groups regarding mortality and MACE. Conclusion: The incidence of CIN was nearly equal in very early PCI (within 3-12 hours) versus early PCI (within 12-24 hours); however, the incidence of no-reflow phenomenon was significantly higher in patients subjected to early PCI (within 12-24 hours).

Incidence, predictors, and outcomes of new-onset atrial fibrillation in patients with ST-elevation myocardial infarction.

BACKGROUND: Atrial fibrillation (AF) is a common arrhythmia and one of the complications in the setting of ST-elevation myocardial infarction (STEMI). Our objective of the present study was to investigate the incidence, predictors, and outcomes of NOAF in patients with acute STEMI managed with pharmacoinvasive strategy (PIS) versus those managed with primary percutaneous coronary intervention (PPCI). METHODS: The study included 530 patients with STEMI divided into two groups according to the method of treatment. Group I: 269 patients subjected to pharmacoinvasive strategy (PIS), group II: 261 patients managed with primary percutaneous coronary intervention (PPCI). Incidence, predictors, and outcomes of NOAF were assessed in each group separately. RESULTS: The incidence of NOAF was 25 patients (9.3%) in group I and 24 patients (9.2%) in group II. Multivariate regression analysis identified the independent predictors of NOAF that were (advanced age ˃65 years, history of hypertension, left atrial volume index (LAVI) ˃34 ml/m2 , E/e' ratio ˃ 12, right coronary artery (RCA) as a culprit vessel and presence of heart failure). There was no statistically significant difference between both groups regarding the occurrence of MACE. CONCLUSION: New-onset AF represents one of the common complications in the setting of STEMI. Advanced age, hypertension, LAVI ˃34 ml/m2 , E/e' ratio ˃12, RCA culprit vessel, and heart failure were the independent predictors of NOAF.

Incidence, predictors and outcomes of stress hyperglycemia in patients with ST elevation myocardial infarction undergoing primary percutaneous coronary intervention.

BACKGROUND: Stress hyperglycemia is a common finding during ST elevation myocardial infarction in diabetic patients and is associated with a worse outcome. However, there are limited data about stress hyperglycemia in non-diabetic patients and its outcome especially in patients undergoing primary percutaneous coronary intervention. METHODS: The study was conducted on 660 patients with ST elevation myocardial infarction who were managed with primary percutaneous coronary intervention. Patients were classified into two groups according to the presence of stress hyperglycemia: group I (patients with stress hyperglycemia) and group II (patients without stress hyperglycemia). Patients were analysed for clinical outcome including mortality and the occurrence of major adverse cardiac events. RESULTS: Incidence of stress hyperglycemia was 16.8%, multivariate regression analysis identified the independent predictors of stress hyperglycemia, that were family history of diabetes mellitus odds ratio 1.697 (95% confidence interval: 1.077-2.674, p = 0.023), body mass index >24 kg/m2 odds ratio 1.906 (95% confidence interval: 1.244-2.922, p = 0.003) and cardiogenic shock on admission odds ratio 2.517 (95% confidence interval: 1.162-5.451, p = 0.019). Mortality, cardiogenic shock, contrast induced nephropathy and no reflow phenomenon were significantly higher in stress hyperglycemia group with p value = 0.027, 0.001, 0.020 and 0.037, respectively. CONCLUSION: Stress hyperglycemia in non-diabetic patients with ST elevation myocardial infarction undergoing primary percutaneous coronary intervention is associated with increased incidence of no reflow phenomenon, contrast induced nephropathy, cardiogenic shock and higher mortality.

Predictors of poorly developed coronary collateral circulation in patients with subclinical hypothyroidism suffered from chronic stable angina.

Background. The development of coronary collaterals is variable among patients with coronary artery disease and remains incompletely understood. We aimed to demonstrate the predictors of poorly developed coronary collateral circulation (CCC) in patients with subclinical hypothyroidism suffered from chronic stable angina. Methods. The study was conducted on 226 patients with subclinical hypothyroidism suffered from chronic stable angina, coronary angiography documented total occlusion at any major coronary artery or coronary artery lumen diameter stenosis >90%. Patients were divided into two groups according to grade of CCC, group A: 138 patients with (good collaterals) and group B: 88 patients with (poor collaterals). To classify CCC, we used Rentrop's classification. Results. Multivariate regression analysis was performed and identified the independent predictors of poor coronary collaterals: N/L ratio (OR 0.413, CI 95% [0.172-0.993], p = 0.048), and TSH (OR 2.511, CI 95% [1.784-3.534], p = 0.001). The ROC analysis provided a cut-off value of >4.6 for N/L ratio, and >9 µIU/mL for TSH to predict poor coronary collaterals. Conclusion. An elevated level of N/L ratio >4.6 and TSH level >9 µIU/mL were the independent predictors of poorly developed CCC in patients with subclinical hypothyroidism suffered from chronic stable angina.

Right ventricular 2D speckle-tracking echocardiography in children with osteosarcoma under chemotherapy.

BACKGROUND: Cardiotoxicity from anthracyclin chemotherapy is a leading cause of death in patients with cancer. Therefore, left ventricular (LV) function is routinely assessed during protocol to detect cardiotoxicity; however, animal studies suggest that right ventricular (RV) function may be also impaired. So, our objective was to investigate the incidence of RV dysfunction in children with osteosarcoma receiving anthracyclines and to highlight the role of 2D STE in early detection of RV dysfunction. RESULTS: RV function was affected by anthacyclines through direct cardiotoxic effect on RV myocardium without simultaneous derangement of LV function. Furthermore, there is a direct proportion between the incidence of RV dysfunction and the cumulative dose of anthracyclines. At the first echo follow-up at 10th week, 7 patients had impaired RV GLS in comparison to baseline study. At 20th week, the number of patients with impaired RV strain increased to 10. At 29th week, it reaches 12 patients. This effect was early detected by RV 2DSTE before adversely affecting TAPSE and FAC. The incidence of RV dysfunction from anthracyclines was around 12%, and the recovery rate was around 8% in 3 months after completion of chemotherapy. CONCLUSION: RV 2DSTE is the best modality to detect early affection of RV function in comparison with other modalities. RV function decreases early even before derangement of LV function. Accordingly, it should be assessed separately in all patients who received anthracyclines even without evident LV affection.

Contrast-Induced Nephropathy in Patients With ST-Segment Elevation Myocardial Infarction: Is it Affected by Treatment Strategy?

BACKGROUND: Contrast-induced nephropathy (CIN) is a frequent complication after percutaneous coronary intervention (PCI) and severely affects morbidity and mortality, especially in patients with ST-segment elevation myocardial infarction. OBJECTIVE: This study sought to determine the incidence, risk factors, and in-hospital outcome of CIN in patients with ST-segment elevation myocardial infarction managed by pharmacoinvasive strategy (PIS) versus those managed by primary PCI (PPCI). METHODS: The study was conducted on 670 patients with ST-segment elevation myocardial infarction divided into 2 groups: group I (PPCI group) and group II (PIS group), the 2 groups were compared with each other for the incidence of CIN, risk factors, and in-hospital major adverse cardiac events. RESULTS: The incidence of CIN in the PIS group (30 patients, 8.8%) was lower than PPCI group (36 patients, 10.9%); however, there was no statistically significant difference between the 2 groups (p = 0.365). Multivariate regression analysis showed that advanced age >60 years (odds ratio [OR] = 4.453; 95% confidence interval [CI]: 2.489 to -7.967; p = 0.001), history of diabetes mellitus (OR = 2.366; 95% CI: 1.298 to -4.315; p = 0.005) and hypertension (OR = 1.930; 95% CI: 1.053 to -3.539; p = 0.034), volume of contrast agent >180 ml (OR = 2.276; 95% CI: 1.290 to -4.016; p = 0.005), and cardiogenic shock (OR = 4.098; 95% CI: 1.726 to -9.728; p = 0.001) were the independent predictors of CIN. Mortality and major adverse cardiac events were significantly higher in patients with CIN. CONCLUSIONS: The incidence of CIN was slightly lower in PIS as compared to PPCI; however, this reduction was not statistically significant. The independent predictors of CIN were advanced age, history of diabetes mellitus and hypertension, high dose of contrast agent, and cardiogenic shock.

[Spontaneous rupture of hydatid cyst of liver in the peritoneal cavity with intact proligerous membrane: about a case and literature review]. / Rupture spontanée d'un kyste hydatique du foie dans la cavité péritonéale avec une membrane proligère intacte: à propos d'un cas et revue de la littérature.

Rupture of hydatid cyst of liver with intact proligerous membrane is rare. We report the case of a 63 year-old female patient presenting with right hypocondrium pain without fever or jaundice. Diagnostic imaging examination showed hydatid cyst in segment IV of liver associated with pelvic cystic lesion measuring 12 cm x 06 cm. Surgical exploration revealed ruptured unilocular hydatid cyst of the liver with intact proligerous membrane and free in the peritoneal cavity. This study aims to report a new case of intraperitoneal rupture of hydatid cyst of liver with intact proligerous membrane and to highlight the diagnostic and therapeutic difficulties due to this complication.
