Abstract
Immunoglobulin M (IgM) autoantibodies to oxidation-specific epitopes (OSEs) can be present at birth and protect against atherosclerosis in experimental models. This study sought to determine whether high titers of IgM titers to OSE (IgM OSE) are associated with a lower risk of acute myocardial infarction (AMI) in humans. IgM to malondialdehyde (MDA)-LDL, phosphocholine-modified BSA, IgM apolipoprotein B100-immune complexes, and a peptide mimotope of MDA were measured within 24 h of first AMI in 4,559 patients and 4,617 age- and sex-matched controls in the Pakistan Risk of Myocardial Infarction Study. Multivariate-adjusted logistic regression was used to estimate odds ratio (OR) and 95% confidence interval for AMI. All four IgM OSEs were lower in AMI versus controls (P < 0.001 for all). Males, smokers and individuals with hypertension and diabetes had lower levels of all four IgM OSE than unaffected individuals (P < 0.001 for all). Compared to the lowest quintile, the highest quintiles of IgM MDA-LDL, phosphocholine-modified BSA, IgM apolipoprotein B100-immune complexes, and MDA mimotope P1 had a lower OR of AMI: OR (95% confidence interval) of 0.67 (0.58-0.77), 0.64 (0.56-0.73), 0.70 (0.61-0.80) and 0.72 (0.62-0.82) (P < 0.001 for all), respectively. Upon the addition of IgM OSE to conventional risk factors, the C-statistic improved by 0.0062 (0.0028-0.0095) and net reclassification by 15.5% (11.4-19.6). These findings demonstrate that IgM OSE provides clinically meaningful information and supports the hypothesis that higher levels of IgM OSE may be protective against AMI.

Abstract
INTRODUCTION COVID-19 restrictive containment was responsible for major psychological distress and alteration of quality of life (QoL) in the general population. Their impact in a group of patients having cerebral small vessel disease (SVD) and at high risk of stroke and disability was unknown. OBJECTIVE We aimed to determine the potential psychological impact of strict containment during the COVID-19 pandemic in a sample of CADASIL patients, a rare SVD caused by NOTCH3 gene mutations. METHODS Interviews of 135 CADASIL patients were obtained just after the end of the strict containment in France. Depression, QoL and negative subjective experience of the containment were analysed, as well as predictors of posttraumatic and stressor-related manifestations, defined as an Impact Event Scale-Revised score ≥ 24, using multivariable logistic analysis. RESULTS Only 9% of patients showed a depressive episode. A similar proportion had significant posttraumatic and stressor-related disorder manifestations independently associated only with socio-environment factors, rather than clinical ones: living alone outside a couple (OR 7.86 (1.87-38.32), unemployment (OR 4.73 (1.17-18.70)) and the presence of 2 or more children at home (OR 6.34 (1.35-38.34). CONCLUSION Psychological impact of the containment was limited in CADASIL patients and did not appear related to the disease status. About 9% of patients presented with significant posttraumatic and stressor-related disorder manifestations which were predicted by living alone, unemployment, or exhaustion related to parental burden.

Abstract
BACKGROUND AND PURPOSE By studying the evolution of brain volume across the life span in male and female patients, we aimed to understand how sex, brain volume, and the epidermal growth factor repeat domain of the mutation, the 3 major determinants of disability in CADASIL, interact in driving disease evolution. MATERIALS AND METHODS We used validated methods to model the evolution of normalized brain volume with age in male and female patients using nonparametric regression in a large, monocentric cohort with prospectively collected clinical and high-resolution MR imaging data. We used k-means clustering to test for the presence of different clinical course profiles. RESULTS We included 229 patients (mean age, 53 [SD, 12] years; 130 women). Brain volume was larger in women (mean size, 1024 [SD, 62] cm3 versus 979 [SD, 50] cm3; P < .001) and decreased regularly. In men, the relationship between brain volume and age unexpectedly suggested an increase in brain volume around midlife. Cluster analyses showed that this finding was related to the presence of a group of older male patients with milder symptoms and larger brain volumes, similar to findings of age-matched women. This group did not show specific epidermal growth factor repeat domain distribution. CONCLUSIONS Our results demonstrate a detrimental effect of male sex on brain volume throughout life in CADASIL. We identified a subgroup of male patients whose brain volume and clinical outcomes were similar to those of age-matched women. They did not have a specific distribution of the epidermal growth factor repeat domain, suggesting that yet-unidentified predictors may interact with sex and brain volume in driving disease evolution.

Abstract
BACKGROUND European member states are increasingly vying with one another to recruit patients for clinical trials (CTs). The French national agency for medicines (ANSM) now receives an ever-growing number of CTs, extending response times. The aim of the new methodology presented herein is to reduce assessment times below the national mandatory timeframe of 60 days and to improve patient safety. MATERIALS AND METHODS Based on an analysis of the criteria defining CTs, 4 key points were identified (safety, fragile population, loss of opportunity, design complexity) to build a criticality score which would determine evaluation type. This score also determines the resources needed (complete evaluation, multidisciplinary advice, ad hoc evaluation) and the timeframe required for appropriate analysis. All post-phase I CTs were analysed from the implementation of the new assessment method, on 01/02/2018 through to 31/12/2019. RESULTS 447 CTs were analysed (63% industry and 37% academic sponsors). Based on a criticality scale, 27% of the CTs received a type A evaluation (complete), 37% a type B (multidisciplinary evaluation), 23% a type C evaluation (ad hoc evaluation) and 13% a type D evaluation (fast evaluation). From 2014 to 2017, 37% of the CTs were analysed within the mandatory timeframe, with a mean of 68 days, reaching a maximum of 102 days in 2017. Using this new assessment method, 92% of CTs respected the mandatory timeframe in 2019; the mean time in 2018-2019 was 34 days; Grounds for Non-Acceptance (GNA) were raised for 66% of the CTs (69% from academic sponsors and 65% from industrial firms). 3 CTs were refused. CONCLUSION Here, we demonstrate the feasibility of risk analysis and multidisciplinarity method, which resulted in a dramatic improvement of assessment times.

Abstract
Objectives We sought to determine the effect of COVID‐19 related reduction in elective cardiac procedures and acute coronary syndrome presentations on interventional cardiology (IC) training. Background The COVID‐19 pandemic has significantly disrupted healthcare in the United States, including cardiovascular services. The impact of COVID‐19 on IC fellow training in the United States has not been assessed. Methods The Society for Cardiovascular Angiography and Interventions (SCAI) surveyed IC fellows training in both accredited and advanced non‐accredited programs, as well as their program directors (PD). Results Responses were received from 135 IC fellows and 152 PD. All respondents noted reductions in procedural volumes beginning in March 2020. At that time, only 43% of IC fellows had performed >250 PCI. If restrictions were lifted by May 15, 2020 78% of IC fellows believed they would perform >250 PCI, but fell to only 70% if restrictions persisted until the end of the academic year. 49% of IC fellows felt that their procedural competency was impaired by COVID‐19, while 97% of PD believed that IC fellows would be procedurally competent at the end of their training. Most IC fellows (65%) noted increased stress at work and at home, and many felt that job searches and/or existing offers were adversely affected by the pandemic. Conclusion The COVID‐19 pandemic has substantially affected IC training in the United States, with many fellows at risk of not satisfying current program procedural requirements. These observations support a move to review current IC program requirements and develop mitigation strategies to supplement gaps in education related to reduced procedural volume.

Abstract
INTRODUCTION Lack of recent data on asthma control in Algeria led to this study whose results were compared with those of the same study conducted in the Middle East and North Africa (MENA). METHOD This cross-sectional epidemiological study was performed in adults who had been diagnosed with asthma for at least one year and without exacerbation within the last 4 weeks. Asthma control was assessed using the 2012 Global Initiative for Asthma (GINA) criteria and the Asthma control test (ACT) questionnaire. RESULTS We studied 984 patients mainly managed by specialist physicians; 61% female, mean age 45 years, body mass index 27kg/m2, active smokers 2%. Medication was prescribed in 92% with 78% receiving inhaled corticosteroids alone or with add-on therapies. Good adherence was observed in 27%. Asthma control was observed in 34.6% vs. 28.6% in other countries (P < 0.001). Low level of education, absence of medical insurance, lack of physical exercise, and-long duration of the disease were significantly associated with uncontrolled asthma. CONCLUSION Poor control of asthma is still observed in Algeria despite a high level of specialist involvement. Except for adherence, known predictive factors of poor asthma control have been observed. Quality improvement training of health care professionals and patient education are probably the main issues to be addressed.

Abstract
Metals in river sediments from a semi-arid Mediterranean basin were investigated from upstream to downstream during contrasting hydrological conditions in 2014 and 2015. The level and origin of the contamination were evaluated using several geochemical and isotopic indicators. Elements were grouped by their level of contamination: high (Pb > Cd > Zn > Cu) and low (Al, Fe, Cr, Co, Ni). Multiple local sources of contamination were identified (industrial, agricultural and domestic waste), as well as very specific ones (gasoline station) and diffuse pollution from atmospheric deposition (gasoline, ores, aerosols). During storm events, the upstream dams can either be secondary sources of contamination or dilutors through particles derived from natural erosion. The contamination was slowed downstream due to the river geomorphology, but eventually washed into the Mediterranean Sea by intense storm events. Naturally derived elements (Co, Ni, Cr, As) were associated with Al, Fe and Mn oxides or clays, and anthropogenic originated metals with phosphorus (Cd and Zn), sulphur (Cu) and POC (Pb enrichment). Cadmium and Pb were the most available metals upstream and at the outlet, but their availability was not strictly related to their degree of contamination. These conclusions could be drawn thanks to an approach by multiple indicators.

Abstract
OBJECTIVE To evaluate the effect of 25 (OH) vitamin D supplementation on blood pressure (BP) variability in hypertensive women in the pre-menopausal and post-menopausal periods. MATERIALS AND METHODS 881 hypertensive women prospectively followed for an interventional study between January 2016 and September 2017, in specialized consultation at the department of internal medicine at the Blida University Hospital (Algeria). Four hundred and thiry nine premenopausal women (group I) and 442 menopausal women (group II). The initial serum 25 (OH) D level for each group was determined by the enzyme immunoassay. In groups I and II, we identified 2 subgroups, A: insufficiency (vit D between 29 and 20ng/ml) and B: deficiency (vit D less than 20ng/L). Antihypertensive therapy was supplemented with an additional 200000IU/month cholecalciferol for the two B subgroups. The variability in BP was calculated as the ratio of mean systolic and diastolic BP during daytime and nighttime, with performing ambulatory BP measurement at baseline, 3, 6, and 12 months of follow-up. RESULTS At inclusion, the level of 25 (OH) D was lower (P<0.05) in subgroups IB (19.3±8.5ng/ml) and IIB (18.2±9, 5ng/ml) compared to subgroups IA (28.1±10.7ng/ml) and IIA (25.2±10.1ng/ml). After supplementation, the level of 25 (OH) D increased in subgroup IB (38.3±11.9ng/ml) and in subgroup IIB (37.3±10, 5ng/ml) and became higher (P<0.001) than in subgroups IA and IIA. Between subgroups IA and IB, at inclusion, there is no difference (P>0.05) in the SBP and DBP variability during the day and at night. After treatment, the variability of the SBP at night became lower (P<0.02) in group IB compared to group IA. In subgroup IIB, daytime variability indices were higher (P=0.04) at inclusion than in group IIA. After treatment, the variability of SBP during the day decreased but remained the highest (P<0.05) in subgroup IIB (14.8±10.8mmHg) compared to subgroup IB (12.0±8.1mmHg), as well as to subgroups IIA (10.9±9.8mmHg) and IA (10±8.1mmHg). We found a significant correlation of cholecalciferol with the variability of SBP during the day. CONCLUSIONS Vitamin D deficiency appears to be a factor of BP variability. Although the variability of the postmenopausal group remains higher than that of the other groups, the correction of the level of 25 (OH) D by the supply of cholecalciferol 200000 IU per month leads to a reduction in the variability of BP in the studied hypertensive women could help to prevent morbimortal complications.

Abstract
PURPOSE Diabetes mellitus (DM) and lipid disorders (LD) in hypertensive patients are associated with an increased risk of cardiovascular complications requiring follow-up and more aggressive therapeutic strategies. The main objective of this study was to describe the prevalence of DM and LD in adult hypertensive patients followed in specialized consultation of hypertension in the region of Blida (North Algeria) during the period from January 2013 to June 2017. MATERIALS AND METHODS We included 3268 hypertensive patients (1453 men and 1815 women), mean age of 58.3±13.8years. Descriptive statistics were used to estimate means by sex and age for subgroups [under 30, 30-39, 40-49, 50-60, over 70]. A linear regression was used to determine annual trends. The age and sex specific results were adjusted to the general population data of the city of Blida for a period of 4years and each year studied. RESULTS The mean prevalence of diabetes was 21.8% and glucose tolerance was 10.9% without significant trend of increase during the study period in the overall population and according to sex, while in the subgroup of hypertensive patients over 60, there has been an increase in the prevalence of diabetes and a decrease in glucose tolerance over the 4 years (R2=0.78, P=0.05 and R2=0.95, P=0.005, respectively). The mean prevalence of LD for the study period was 16.1% without significant trend at 4years. The increase in total cholesterol combined with the increase in low-density lipoprotein (LDL) levels was the most common disorder (32.2%). There was no significant difference in LD prevalence and characteristics in subgroups by sex. Age group analysis showed a greater increase in the frequency of lipid disorders in patients over 60years of age (R2=0.80, P=0.001). CONCLUSIONS Over the 4years of study, age over 60 was associated with an increase in the prevalence of metabolic disorders in hypertensive patients. This trend may explain the poor control of BP. Above all, it must be taken into account for the requirement to achieve therapeutic objectives that effectively reduce the risk of cardiovascular complications occurring in these high-risk patients whose number is becoming increasingly important.

Abstract
Longitudinal stent deformation, described in some older stent geometries, prompted design modifications such as reinforcing struts on the proximal end. However, distal edges of stents-also subject to longitudinal force-have not been reinforced. We report a case of guidewire entrapment that deformed the distal edge of a new-generation stent during percutaneous coronary intervention, and we describe our efforts to restore the stent to its initial length. This case highlights the risk of manipulating equipment beyond the position of a newly deployed stent, the ongoing potential for deformation of distal edges in newer stent platforms, and the advisability of treating distal lesions before proximal ones.

Abstract
BACKGROUND The lipoprotein(a) pathway is a causal factor in coronary heart disease. We used a genetic approach to distinguish the relevance of two distinct components of this pathway, apolipoprotein(a) isoform size and circulating lipoprotein(a) concentration, to coronary heart disease. METHODS In this mendelian randomisation study, we measured lipoprotein(a) concentration and determined apolipoprotein(a) isoform size with a genetic method (kringle IV type 2 [KIV2] repeats in the LPA gene) and a serum-based electrophoretic assay in patients and controls (frequency matched for age and sex) from the Pakistan Risk of Myocardial Infarction Study (PROMIS). We calculated odds ratios (ORs) for myocardial infarction per 1-SD difference in either LPA KIV2 repeats or lipoprotein(a) concentration. In a genome-wide analysis of up to 17 503 participants in PROMIS, we identified genetic variants associated with either apolipoprotein(a) isoform size or lipoprotein(a) concentration. Using a mendelian randomisation study design and genetic data on 60 801 patients with coronary heart disease and 123 504 controls from the CARDIoGRAMplusC4D consortium, we calculated ORs for myocardial infarction with variants that produced similar differences in either apolipoprotein(a) isoform size in serum or lipoprotein(a) concentration. Finally, we compared phenotypic versus genotypic ORs to estimate whether apolipoprotein(a) isoform size, lipoprotein(a) concentration, or both were causally associated with coronary heart disease. FINDINGS The PROMIS cohort included 9015 patients with acute myocardial infarction and 8629 matched controls. In participants for whom KIV2 repeat and lipoprotein(a) data were available, the OR for myocardial infarction was 0·93 (95% CI 0·90-0·97; p<0·0001) per 1-SD increment in LPA KIV2 repeats after adjustment for lipoprotein(a) concentration and conventional lipid concentrations. The OR for myocardial infarction was 1·10 (1·05-1·14; p<0·0001) per 1-SD increment in lipoprotein(a) concentration, after adjustment for LPA KIV2 repeats and conventional lipids. Genome-wide analysis identified rs2457564 as a variant associated with smaller apolipoprotein(a) isoform size, but not lipoprotein(a) concentration, and rs3777392 as a variant associated with lipoprotein(a) concentration, but not apolipoprotein(a) isoform size. In 60 801 patients with coronary heart disease and 123 504 controls, OR for myocardial infarction was 0·96 (0·94-0·98; p<0·0001) per 1-SD increment in apolipoprotein(a) protein isoform size in serum due to rs2457564, which was directionally concordant with the OR observed in PROMIS for a similar change. The OR for myocardial infarction was 1·27 (1·07-1·50; p=0·007) per 1-SD increment in lipoprotein(a) concentration due to rs3777392, which was directionally concordant with the OR observed for a similar change in PROMIS. INTERPRETATION Human genetic data suggest that both smaller apolipoprotein(a) isoform size and increased lipoprotein(a) concentration are independent and causal risk factors for coronary heart disease. Lipoprotein(a)-lowering interventions could be preferentially effective in reducing the risk of coronary heart disease in individuals with smaller apolipoprotein(a) isoforms.

Abstract
PURPOSE To compare differences in prevalence rates, treatment and control of hypertension (AHT) between males and females in general medicine consultation in the area of Blida (Algeria). METHODS We included 3622 patients in the study (42% males and 58% females), with a mean age of 48.14±10.11 years, examined between January 2014 and June 2016 in general medicine consultation in the area of Blida (Algeria). Data was collected with individual questionnaires. Measurement of blood pressure was made using validated semi-automatic devices (OMRON HEM model 705CP). Individuals using antihypertensive drugs and/or blood pressure (BP) greater than or equal to 140/90mmHg were considered as hypertensives. The knowledge about the disease was identified among those who claimed to be aware of the diagnosis before the measurements. The treatment rate was calculated with those who reported using antihypertensive drugs. Controlled blood pressure was considered in individuals with values lower than 140/90mmHg. Lipid profile (total cholesterol, triglycerides, HDL and LDL cholesterol), and fasting blood sugar were measured. All calculations and statistical analyses are processed by the SPSS 20.0. RESULTS The prevalence of hypertension was higher among men (46.2%) than women (31.6%) (P<0.001), and among aged over 55 years (P< 0.05) and those that have referred hypertensive parents (P<0.05). Among hypertensive men, 55.7% knew the diagnosis, 63.6% of them were under treatment, and 22% had controlled BP. Among the hypertensive women 69.8% knew the diagnosis, 85.1% were under treatment and 35.6% were with controlled BP (P<0.001 for the three variables). The most frequent associated risk factors were diabetes mellitus in 36.8% of the patients, obesity in 35.7% of the patients, microalbuminuria in 23.6% of the patients, hypercholesterolemia>2g/L in 11.6% of the patients, smoking in 7.7% of them. Presence of controlled AHT was not found to be associated with presence of other risk factors. The likelihood of having AHT was higher among men, diabetics, older subjects and higher BMI. CONCLUSION Our study confirmed the high prevalence of AHT in general medicine consultation in Blida, which is a representative city in the north of Algeria. Although women are better treated, much remains to be done to reach BP goal, much in our countries which have the least financial resources to combat cardiovascular disabilities.

Abstract
BACKGROUND The metastases of a primary lung cancer over the thyroid gland are extremely rare. We report on an unusual presentation of thyroid metastasis of lung cancer in order to improve the management of similar cases. CASE PRESENTATION Three years ago, a Moroccan male 59-year-old was admitted for dyspnea, dry cough, and chest pain. He had smoked about 30 cigarette packs a year. Clinical examination revealed a right thyroid nodule. Chest and neck computed tomography (CT) scan showed a proximal left tumor in contact with the pulmonary artery and revealed a suspected nodule in the right lobe of the thyroid with homolateral neck node. Transbronchial biopsy was performed and pathological examination revealed adenocarcinoma of the lung and positive for thyroid transcription factor. Other explorations carried out, such as brain CT, bone scan and abdominal ultrasound were normal. After a repeated negative fine needle aspiration biopsy of the suspected nodule of the right lobe of the thyroid, we performed total thyroidectomy with neck dissection. An anatomopathologic exam revealed a tubulopapillary adenocarcinoma poorly differentiated. An Immunohistochemistry showed positive tumor cells with TTF1 and cytokeratin (CK) 7 but negative cells with thyroglobulin and CK20. Thus, the pulmonary tumor was classified stage IV. Chemotherapy based on the combination of cisplatin and etoposide was conducted along with supportive care. The tumor grew up with brain metastases after three cycles of chemotherapy. Unfortunately, the patient died 2 months after despite brain radiotherapy. CONCLUSION We presented a medical case of a patient with thyroid metastasis resulting from a pulmonary adenocarcinoma which has rapidly evolved to brain metastases. The prognosis was pejorative in our clinical case (5 months after admission).

Abstract
PURPOSE Mucinous carcinoma of the breast accounts for 1 to 4% of all breast cancer. There are two histological subtypes: mixed mucinous carcinoma, where the ductal carcinoma is associated with the colloid component, and pure mucinous carcinoma, with a favorable prognosis, where the mucus surrounds the tumour tissue and constitutes a mechanical barrier limiting cell invasion and making this form less aggressive. Our study aimed to determine retrospectively the main epidemiological, clinical, biological, and therapeutic features, as well as the prognosis of this rare form of breast carcinoma. MATERIALS AND METHODS The authors report 32 cases of mucinous carcinoma of the breast diagnosed in Mohammed-VI centre for cancer treatment in Casablanca. RESULTS The average tumour size was 4.5cm (0.5-7cm). We found ten positive lymph node dissections, seven of them were of mixed mucinous carcinoma with a tumour size ranging between 4 and 7cm. Mucinous carcinoma was pure in 16 cases, mixed in 14 and a neuroendocrine differentiation was found in two cases. Most tumours were of an intermediate histological grade (n=19) with positive hormonal receptors (68%). After a mean follow-up of 30 months, complete remission was maintained in 92% of evaluable patients. CONCLUSION Mucinous carcinoma is a rare type of breast cancer, with a favourable prognosis for the pure form.

Abstract
Strain selection is one of the primary hurdles facing cost-effective microalgal biodiesel production. Indeed, the strain used affects both upstream and downstream biodiesel production processes. This study presents a screening procedure that considers the most significant criteria in microalgal biodiesel production including TAG production and wet extraction and recovery of TAGs. Fourteen freshwater and seawater strains were investigated. Large variation was observed between the strains in all the screening criteria. The overall screening procedure ultimately led to the identification of Parachlorella kessleri UTEX2229 and Nannochloropsis gaditana CCMP527 as the best freshwater and seawater strains, respectively. They featured the largest areal TAG productivity equal to 2.7×10(-3) and 2.3×10(-3)kgm(-2)d(-1), respectively. These two strains also displayed encouraging cell fragility in a high pressure bead milling process with 69% and 98% cell disruption at 1750bar making them remarkable strains for TAG extraction in wet environment.

Abstract
OBJECTIVE Assess the prevalence, the degree of control, and the comorbidities of hypertension in postmenopausal women. DESIGNS AND METHODS This is a cohort descriptive and prospective study conducted in 2years in a population with hypertension treated for arterial hypertension in specialized university hospital in Blida, which included one thousand seven hundred and twenty-one postmenopausal women with amenorrhea fore more than 12 consecutive months. All anthropometric data were recorded. All cardiovascular complications were sought. All calculations and statistical analysis are processed by the SPSS 20.0. RESULTS The mean age of onset menopause is 50.7±6.2yearsold. The prevalence of hypertension is 71%, significantly higher in postmenopausal women aged 65 and over. Among women, 82.3% had a systolic arterial pressure>150mmHg and 42.2% had a diastolic arterial pressure>90mmHg. The prevalence of diabetes was 34.8%, and 88.4% presented type 2 diabetes. Tobacco in 1.3%, hypoHDLmia in 52%, the hypertriglyceridemia in 43.5%, obesity in 31.7%. The metabolic syndrome in 57.8%. The major cardiovascular complications observed are: stroke in 26.4%, heart failure in 14.8%, myocardial infarction in 13.2%, renal failure in 10.1%. The control of high blood pressure is achieved only in 31.7%. CONCLUSIONS The systolic blood pressure is more important than the diastolic blood pressure in postmenopausal women. The cerebral vascular accident remains the most feared complication. The control of hypertension remains not enough and the balance of arterial pressure figures is highly recommended to avoid morbidity and fatal complications.

Abstract
INTRODUCTION Gemcitabine-induced thrombotic microangiopathy is a rare event whose management is not yet consensual. The use of eculizumab could be of interest. CASE REPORT A 68-year-old woman was treated by gemcitabine as adjuvant chemotherapy of a pancreatic adenocarcinoma. Two months later, the patient presented with mechanical hemolytic anemia, thrombocytopenia and high blood pressure that led to the diagnosis of thrombotic microangiopathy. Gemcitabine was stopped. Plasma exchange therapy was introduced since hematological and renal parameters had worsened. As clinical efficacy was insufficient, eculizumab was introduced at a dose of 900 mg per week 4 times, then 1200 mg every 2 weeks. Symptoms along with hematological and nephrological analysis were back to physiological standards after 7 intravenous injections. CONCLUSION Eculizumab seems to be an effective treatment against gemcitabine-induced thrombotic microangiopathy in case of severe hematological and renal injuries associated with a lack of response to plasma exchange therapy.

Abstract
Nannochloropsis has emerged as a promising alga for biodiesel production. However, the genus consists of 6 species and hundreds of strains making strain selection a challenge. Furthermore, oil productivity is instrumental to economic viability of any algal strain for industrial production, which is dependent on growth rate and oil content. In most cases, these two parameters have been studied independently. Thus, the goal of this study is to provide a combined method for evaluating strain performance in specially designed photobioreactors together with an in-depth lipidomic analyses. The nine strains of Nannochloropsis tested showed considerable variations in productivity and lipidomics highlighting the importance of strain selection. Finally, Nannochloropsis gaditana CCMP527 and Nannochloropsis salina CCMP537 emerged as the two most promising strains, with an oil content of 37 and 27 dry wt% after 11-day nitrogen starvation, respectively, resulting in TAG productivity of 13×10(-3) and 18×10(-3) kg m(-3) d(-1), respectively.

Abstract
INTRODUCTION Arterial hypertension is a major public health problem not only internationally, but also in our country, and it is the major risk factor for cardiovascular diseases. In south Algeria, the black population is nearly half the population of the oases of the Algerian Sahara. THE OBJECTIVES OF THE STUDY The objectives of the study are to analyze the long-term fate of the black hypertensive subjects in Algerian oases in southern Algeria, in terms of morbidity and mortality, comparing the morphometric profile and cardiovascular complications with the white population of the same oases. MATERIALS AND METHODS One thousand four hundred and twenty-five subjects of both sexes were included (811 blacks and 614 white subjects), aged 40 and older, living in the Algerian Sahara and were reviewed after six years of decline. The control consisted of filling a questionnaire oriented on civil status, target organ damage, the number of hospitalizations and mortality. All calculations and statistical analyzes are processed by the SPSS 17.0 and Epi Info6 software. RESULTS Mean age for the black population and the white population was 60.3±11.1 and 58.6±10.6years, respectively. The incidence of hypertension was 50 % among blacks. The main complications observed were: stroke in 3.8 %, heart failure in 3.1 %, myocardial infarction in 1.7 %, hospitalizations related to cardiovascular complications of the black population was around 4.4 %, mortality 5.4 %. CONCLUSION These data on hypertension black subjects emphasize the importance of a policy of adequate local health issues raised, both in terms of the management of hypertension, as in investment in local medical research.

Abstract
Cholesterol is a structural component of the cell, indispensable for normal cellular function, but its excess often leads to abnormal proliferation, migration, inflammatory responses and/or cell death. To prevent cholesterol overload, ATP-binding cassette (ABC) transporters mediate cholesterol efflux from the cells to apolipoprotein A-I (ApoA-I) and to the ApoA-I-containing high-density lipoprotein (HDL)1-3. Maintaining efficient cholesterol efflux is essential for normal cellular function4-6. However, the role of cholesterol efflux in angiogenesis and the identity of its local regulators are poorly understood. Here we show that ApoA-I binding protein (AIBP) accelerates cholesterol efflux from endothelial cells (EC) to HDL and thereby regulates angiogenesis. AIBP/HDL-mediated cholesterol depletion reduces lipid rafts, interferes with VEGFR2 dimerization and signaling, and inhibits VEGF-induced angiogenesis in vitro and mouse aortic neovascularization ex vivo. Remarkably, Aibp regulates the membrane lipid order in embryonic zebrafish vasculature and functions as a non-cell autonomous regulator of zebrafish angiogenesis. Aibp knockdown results in dysregulated sprouting/branching angiogenesis, while forced Aibp expression inhibits angiogenesis. Dysregulated angiogenesis is phenocopied in Abca1/Abcg1-deficient embryos, and cholesterol levels are increased in Aibp-deficient and Abca1/Abcg1-deficient embryos. Our findings demonstrate that secreted AIBP positively regulates cholesterol efflux from EC and that effective cholesterol efflux is critical for proper angiogenesis.

Abstract
OBJECTIVES The goal of this study was to examine the prospective association between oxidation-specific biomarkers, primarily oxidized phospholipids (OxPL) on apolipoprotein B-100-containing lipoproteins (OxPL/apoB) and lipoprotein (a) [Lp(a)], and risk of peripheral artery disease (PAD). We examined, as secondary analyses, indirect measures of oxidized lipoproteins, including autoantibodies to malondialdehyde-modified low-density lipoprotein (MDA-LDL) and apolipoprotein B-100 immune complexes (ApoB-IC). BACKGROUND Biomarkers to predict the development of PAD are lacking. OxPL circulate in plasma, are transported by Lp(a), and deposit in the vascular wall and induce local inflammation. METHODS The study population included 2 parallel nested case-control studies of 143 men within the Health Professionals Follow-up Study (1994 to 2008) and 144 women within the Nurses' Health Study (1990 to 2010) with incident confirmed cases of clinically significant PAD, matched 1:3 to control subjects. RESULTS Levels of OxPL/apoB were positively associated with risk of PAD in men and women: pooled relative risk: 1.37, 95% confidence interval: 1.19 to 1.58 for each 1-SD increase after adjusting age, smoking, fasting status, month of blood draw, lipids, body mass index, and other cardiovascular disease risk factors. Lp(a) was similarly associated with risk of PAD (pooled adjusted relative risk: 1.36; 95% confidence interval: 1.18 to 1.57 for each 1-SD increase). Autoantibodies to MDA-LDL and ApoB-IC were not consistently associated with risk of PAD. CONCLUSIONS OxPL/apoB were positively associated with risk of PAD in men and women. The major lipoprotein carrier of OxPL, Lp(a), was also associated with risk of PAD, reinforcing the key role of OxPL in the pathophysiology of atherosclerosis mediated by Lp(a).
