Accumulation of heavy metals from single and combined olive mill wastewater and pomace in soil and bioaccumulation in tissues of two earthworm species: Endogeic (Aporrectodea trapezoides) and Epigeic (Eisenia fetida)
No full textSoil and earthworms are threatened by anthropogenic contamination resulting from olive mill waste dumping on the soil due to their pollutant properties. While several studies have explored the effects of olive mill waste on soil properties and the accumulation of heavy metals in soil, there is currently a gap in the literature regarding the potential bioaccumulation of heavy metals from olive mill waste in earthworms. In this study, soil with earthworms from two ecological categories (endogeic: Aporrectodea trapezoides and epigeic: Eisenia fetida) was treated with increasing doses of olive mill wastewater (OMWW) and olive mill pomace (OMP), applied individually or combined, in an indoor experiment in plastic containers, under laboratory conditions. The results revealed the presence of significant concentrations of heavy metals in the two types of wastes ranging as follows: Fe˃ Zn˃ Cu˃ Cd˃ Cr for OMWW, and Fe˃ Zn˃ Cu˃ Cr for OMP (with Cd below the detection limit). The study demonstrated distinct effects of OMWW and OMP, both individually and in combination, on soil heavy metal content, ranging as follows: soil OMWW > soil Combination > soil OMP for Cd; soil Combination > soil OMWW > soil OMP for Cr and Fe; and soil Combination > soil OMP > soil OMWW for Cu and Zn. Additionally, our investigation showed that both earthworm species exhibited significant uptake of these metals into their tissues, particularly the endogeic species. Interestingly, the most significant difference between species was in the accumulation of Cu, with the epigeic species accumulating significantly lower amounts.

Cardiac hydatid cyst revealed by ventricular tachycardia
No full textAbstractHydatid disease is a human parasitic infestation caused by the larval stage of Echinococcus Granulosus. The liver and the lungs are the most common locations. Cardiac involvement is rare and accounts for 0.5–2% of all hydatid disease. We report an unusual presentation of cardiac hydatid cyst revealed by ventricular tachycardia in a patient with a history of cerebral hydatid cyst
An unusual case of Behçet's disease presenting with postpartum ovarian iliac vein thrombosis and pulmonary embolism
No full textAbstract Thrombosis of the ovarian vein is a rare complication which arises classically in the postpartum. We report a case of 24-year-old woman with a history of Behçet's disease, who presented with pelvic and thoracic pain, tachycardia, dyspnea and fever occurring 2 weeks after delivery. Computed tomography revealed an ascending thrombosis of the iliac and right ovarian veins complicated by bilateral pulmonary embolism. The patient responded well to the combination of anticoagulants and immunosuppressive agents. Behçet's disease should also be considered as an etiologic factor for ovarian vein thrombosis.</p

Time courses of apoptosis and cell proliferation and their relationship to arterial remodeling and restenosis after angioplasty in an atherosclerotic rabbit model
No full textAbstractObjectivesWe sought to evaluate whether cellular mass changes (including apoptosis and proliferation) after arterial injury could interact with restenosis and arterial remodeling.BackgroundThe mechanisms controlling arterial remodeling after angioplasty remain poorly understood. Apoptosis and cell proliferation have been previously described after balloon angioplasty. However, their importance in the occurrence of arterial remodeling and restenosis is unknown.MethodsAtherosclerosis was induced in 48 femoral arteries of New Zealand White rabbits by air-desiccation and a high-cholesterol diet. One month later, angioplasty was performed in 40 arteries. Apoptosis, cell proliferation, residual stenosis and arterial remodeling were evaluated at 2 h and 3, 7, 14, 21 and 28 days after angioplasty.ResultsCell proliferation and apoptosis profiles were similar, but the peak in cell proliferation occurred approximately four days earlier than the peak in apoptosis in the neointima and media. Apoptosis density was positively correlated with arterial remodeling in the neointima and media (r = 0.69, p = 0.005 and r = 0.50, p = 0.05, respectively). Moreover, residual stenosis was inversely correlated with apoptosis density in the neointima and media (r = −0.62, p = 0.008 and r = −0.52, p = 0.04, respectively). In contrast, cell proliferation was independent of restenosis and arterial remodeling.ConclusionsIn this model, cell proliferation preceded apoptosis throughout the four weeks after angioplasty. Apoptosis was inversely correlated with restenosis. Interestingly, apoptosis was also related to enlargement remodeling after balloon angioplasty
0308: Obstructive sleep apnea and acute coronary syndromes: comparison of clinical and angiographic characteristics
No full textIntroductionObstructive sleep apnea hypopnea syndrome (OSAHS) is associated with a range of cardiovascular diseases and increase cardiovascular mortality.AimThe aim of this study was to compare the clinical and angiographic characteristics of patients admitted for acute coronary syndromes (ACS) with and without OSAHS.MethodsWe examined the apnea hypopnea index (AHI) using polygraphy (PG) in 60 consecutive patients with ACS who underwent coronary angiography. OSAHS was defined by AHI≥5 events per hour. The Friesinger score was calculated for each patient from the coronary angiography.ResultsThe average age of patients was 59.73 years±10.1 years. The sex ratio was 1.5. The distribution of risk factors was as follows: hypertension in 61.7% of cases, diabetes in 58.4% of cases, smoking in 51.7% of cases and dyslipidemia in 40% of cases. The mean body mass index (BMI) was 27.98kg/m2.The average of ejection fraction was 54%±15.87.61,7% of patients had an AHI≥5. There were no differences between patients having OSAHS and those without OSAHS regarding clinical and angiographic characteristics. The table summarizes these results.Abstratct 0308 – Table: Comparison of patients with and without OSAHSOSAHS n=37No OSAHS n=23PAge61,22±9,357,35±11,20,15Male35%25%0,51BMI27,94±3,9328,05±4,040,92Smoking28,3%23,3%0,26Hypertension40%21,7%0,51Ddiabetes31,7%26,7%0,16BMI27,94±3,9328,05±4,040,923 vessel disease (%)21,7%16,70,51Friesinger score8,6±4,88,65±5,440,97ConclusionIn conclusion, we noted a high incidence of OSAHS in ACS in our population. There is no difference between ACS patients with and without OSAHS. This latter doesn’t seem related to the severity of the coronary disease. Further studies are needed to evaluate the impact of the presence of OSAHS on short and long term prognosis
0380: Study of anatomical features of pulmonary veins assessed by computed tomography according to age
No full textIntroductionPulmonary veins (PV) play a crucial role in triggering and generating atrial fibrillation (AF). Isolation of PVs is fundamental in the AF ablation whether paroxysmal or persistent. The presence of four distinct pulmonary veins (two left PVs and two right PVs) has been described as the normal variant.AimThe purpose of our study was to investigate whether the age of the patients had an influence on the incidence of anatomical abnormalities of PVs.MethodsOur study was a prospective study which has included 38 patients followed for AF in the cardiology’s department of our hospital. All patients underwent a CT scan of PVs in order to characterize their anatomy. PVs’ size was represented by the largest diameter. We have divided our cohort into two groups: group 1: patients aged more than 50 years and group 2: patients aged less than 50 years.ResultsOur patients had a mean age of 50.5±13 years. The majority of our patients had paroxysmal AF (65%), 4 had persistent AF (10%), 9 had prolonged persistent AF (25%).CT Scan of PV results according to age are summarized in table.ConclusionIn our study, we found no significant relationship between age and anatomical abnormalities of the PVs. Hence, it is important to look for these anatomical anomalies whatever was the age of the patients to increase the success rate and to avoid complications during the AF ablation procedures.Abstratct 0380 – Table: Comparison of PV features evaluated by CT scan according to ageGroup 1 Age>50 years old N=20 patientsGroup 2 Age≤50 years old N=18 patientsPThe average left atrium volume140.8±75.78ml75.72±29.10mLP=0.01Mean number of PV3.85±0.484±0.65NSAverage diameter of left PV26.82±8.6825.03±12.29NSAverage diameter of right PV20.58±5.3522.81±6.05NSLeft single ostium forming a core collector4 (20%)3 (16.6%)NSRight single ostium forming a core collector1 (5%)4 (22%)N
0338: Computed tomography evaluation of the anatomical variation of the pulmonary veins in atrial fibrillation
No full textIntroductionThe electrophysiological and anatomical properties of the pulmonary veins (PVs) have been focused on since their crucial role in triggering or generating atrial fibrillation (AF) was first revealed. The presence of four distinct pulmonary veins (two left PVs and two right PVs) has been described as the normal variant.AimThe purpose of our study was to describe the anatomy of the pulmonary veins in a cohort of patients of our country followed for AF.Methods and resultsOur study is a prospective study which has included 38 patients followed for AF in the cardiology’s department of our Hospital. All patients underwent a CT scan of PVs in order to characterize their anatomy. PVs’ size was represented by the largest diameter.Our patients had a mean age of 50.5±13 years. The majority of our patients had paroxysmal AF (65.8%), 4 had persistent AF (10.5%), 9 had prolonged persistent AF (24%). AF occurred in 63.6% of cases in healthy heart and 36.4% in pathological heart, 13 patients had an anatomical variant which represent 34.2% of the population. We had 3.9 PVs in average with a minimum of 3 and a maximum of 5 PVs. The average diameter of different VP was 23.45±9.31mmfor the left PVs and 19.75±7mmfor the right PVs. 7 patients (18.4%) had anatomical variants interesting the left PVs with single ostium forming a core collector left in all cases.Concerning the right pulmonary veins, anatomical variations were found in 15.8% of cases, one patient (2.65%) had a single ostium forming a core right collector and 5 patients (13.15%) had 3 ostia (presence of 1 middle pulmonary veins on the right).ConclusionCardiac CT is a non invasive procedure which can provide a detailed evaluation of the anatomy of the pulmonary veins. The presence of anatomical variations is common in patients with AF. This assessment is recommended to ensure success of the ablation procedure
