RESUMO
OBJECTIVE: Satureja kermanica is a native species with a relatively wide distribution in Iran, which has been studied less. Due to the low stability of the plants, in this study, the methanolic extract of S. kermanica (MSK) along with a nanoemulsion (NEK) preparation was evaluated in terms of antioxidant and cytotoxic activity. MATERIAL AND METHODS: The aerial parts of S. kermanica were collected and after studying the organoleptic characteristics and quality control parameters, were extracted with methanol. Total phenolic compounds and total flavonoids of the plant were measured. A nanoemulsion preparation was prepared using ultrasonication method from S. kermanica extract. After measuring the particle size of nanoemulsion, both MSK and NEK were evaluated for their antioxidant and cytotoxic activity using DPPH scavenging assay and MTT colorimetric method on breast cancer cell line (MCF-7) respectively. RESULTS: Phytochemical studies exhibited the presence of secondary metabolites including flavonoids, tannins, steroids and carbohydrates in the plant. Based on the histogram of the SBL nanosizer, the average diameter of nanoemulsion was determined as 37.09nm. Both MSK and NEK showed dose-dependent antioxidant and cytotoxic activity. The IC50 value of MSK and NEK for DPPH inhibition was 30.105±2.781 58.14±0.84µg/mL and for toxicity toward MCF-7 cell line was 1251.088 and 201.745±4.554µg/mL respectively. CONCLUSION: MSK and NEK showed antioxidant and cytotoxic activity, but in NEK, the antioxidant and cytotoxic potential of the plant was more prominent, which may be due to the rapid release of the bioactive component from the nanoemulsion.

SARS-CoV-2 is mutating and creating divergent variants across the world. An in-depth investigation of the amino acid substitutions in the genomic signature of SARS-CoV-2 proteins is highly essential for understanding its host adaptation and infection biology. A total of 9587 SARS-CoV-2 structural protein sequences collected from 49 different countries are used to characterize protein-wise variants, substitution patterns (type and location), and major substitution changes. The majority of the substitutions are distinct, mostly in a particular location, and lead to a change in an amino acid's biochemical properties. In terms of mutational changes, envelope (E) and membrane (M) proteins are relatively more stable than nucleocapsid (N) and spike (S) proteins. Several co-occurrence substitutions are observed, particularly in S and N proteins. Substitution specific to active sub-domains reveals that heptapeptide repeat, fusion peptides, transmembrane in S protein, and N-terminal and C-terminal domains in the N protein are remarkably mutated. We also observe a few deleterious mutations in the above domains. The overall study on non-synonymous mutation in structural proteins of SARS-CoV-2 at the start of the pandemic indicates a diversity amongst virus sequences.

Mesenchymal stem cells (MSCs) have proven powerful potential for cell-based therapy both in regenerative medicine and disease treatment. Human umbilical cords and exfoliated deciduous teeth are the main sources of MSCs with no donor injury or ethical issues. The goal of this study was to investigate the differences in the biological characteristics of human umbilical cord mesenchymal stem cells (UCMSCs) and stem cells from human exfoliated deciduous teeth (SHEDs). UCMSCs and SHEDs were identified by flow cytometry. The proliferation, differentiation, migration, chemotaxis, paracrine, immunomodulatory, neurite growth-promoting capabilities, and acetaldehyde dehydrogenase (ALDH) activity were comparatively studied between these two MSCs in vitro. The results showed that both SHEDs and UCMSCs expressed cell surface markers characteristic of MSCs. Furthermore, SHEDs exhibited better capacity for proliferation, migration, promotion of neurite growth, and chondrogenic differentiation. Meanwhile, UCMSCs showed more outstanding adipogenic differentiation and chemotaxy. Additionally, there were no significant differences in osteogenic differentiation, immunomodulatory capacity, and the proportion of ALDHBright compartment. Our findings indicate that although both UCMSCs and SHEDs are mesenchymal stem cells and presented some similar biological characteristics, they also have differences in many aspects, which might be helpful for developing future clinical cellular therapies.

Enterococcus faecalis is a common pathogen causing refractory periapical periodontitis and secondary intraradicular infections. In this study, E. faecalis YN771 isolated from a re-treated root canal at a stomatology department was used as the host bacterium and was co-cultured with wastewater from the same department and patient samples to isolate a phage that lyses E. faecalis. We studied the biological and genomic characteristics of this phage. Transmission electron microscopy showed that this phage's head is icosahedral in structure, with a head diameter of around 98.4 nm, and a contractile tail of around 228.5 nm in length and a diameter of 17.3 nm. The phage was identified as a member of the Myoviridae family and named PEf771. It is sensitive to proteinase K but resistant to chloroform and Triton X-100. Its lytic cycle is 45 min, burst size is 78, optimal multiplicity of infection is 0.1, lysis spectrum is narrow, and host strain specificity is strong. Its optimal growth temperature is 37 °C, most suitable pH is 6.0, and is sensitive to ultraviolet radiation. Whole-genome sequencing of PEf771 indicated it has a genome size of 151 052 bp, with a GC content of 36.97%, and encodes 197 proteins plus 26 tRNAs. PEf771 is most closely related to E. faecalis phage EFDG1. Phage PEf771 has strong host specificity and lytic ability, so it is important to further characterize this phage and its interaction with E. faecalis.

Pinellia ternata is a traditional Chinese herb that suffers from continuous cropping (CC), which significantly decreases both yield and quality. The influence of CC on the microbiome in P. ternata rhizosphere and the effects of remediation on microbiota by rotational cropping (CR) were assessed by Illumina high-throughput sequencing technology. CC tends to decrease the α-diversities as a function of cultivation time, whereas CR tends to increase them. Differentially abundant analysis showed that microbial structure was important in maintaining the health status of P. ternata rhizosphere. Results suggested that CC soils were mainly enriched for Pseudomonas, Rhizobium, and Streptophyta operational taxonomic units (OTUs), while the CR soils were mainly enriched for Rhizobium, Pseudomonas, Flavobacterium, Sphingomonas, Rhizobacter, and Arthrobacter OTUs. On the basis of the community dissimilarities, we grouped all sample replicates into three post hoc clusters in which soils were defined as healthy, health-suppressed, and health-depressed soils. The three soil types represented different soil physicochemical properties. The activities of the microbiome features, including ammonia oxidizer, sulfate reducer, nitrite reducer, dehalogenation, xylan degrader, sulfide oxidizer, nitrogen fixation, atrazine metabolism, chitin degradation, degraded aromatic hydrocarbons, and chlorophenol degradation, were also considerably different among the three soils.

AIMS: In France, guidelines for cervical cancer screening recommend that women between the ages of 25-65 have a smear test performed once every three years. However, some women are screened significantly more frequently. In this study, we used a data-driven approach as opposed to a traditional hypothesis-driven approach to characterise the population of women who are screened more frequently than advised. METHODS: Data came from an organised cervical cancer screening programme of a French department in the Alps (Isère). We retrospectively selected women aged between 25 to 65 years old who had at least two smear tests during the follow up period (2011-2015). We used a data-driven clustering approach to compare the population of over-screened women with other populations. We then performed a descriptive analysis of the over-screened population using univariate (Chi2 test) and multivariate (logistic regression) methods. RESULTS: A total of 10,000 patients were randomly chosen from a population of 54,073. In our univariate analysis, women in the over-screened population were significantly younger, participated less in organised screening, were more likely to be followed by a gynaecologist and had more smear test results showing inflammation than the other populations. Patient location (urban v.s. rural area) was not significant for this population. The multivariate analysis confirmed these results. CONCLUSION: This data-driven approach based on an unsupervised learning method enables us to more accurately characterise the over-screened population. These data invite to improve communication with the youngest women and the gynecologists to recall the benefit of an interval between two normal smears complying with the recommendations. This approach could help to improve the prevention and have a real impact on this Public Health issue.

OBJECTIVES: To describe the prevalence of CMV in a cohort of HIV infected individuals in Guinea-Bissau, West Africa and to evaluate differences in patients' clinical characteristics associated with their CMV status. METHODS: Newly diagnosed HIV infected adults were invited to participate in this cross-sectional study, from May until December 2015. Enrolled patients were interviewed and underwent a full physical examination focusing on CMV disease manifestations. Blood samples were analysed for CMV serology, QuantiFERON-CMV response and CMV DNA. Mortality follow-up were registered for one year after inclusion. RESULTS: In total, 180 patients were enrolled. Anti-CMV IgG positivity was found in 100% (138/138) and 2.8% (4/138) were anti-CMV IgM positive. A positive QuantiFERON-CMV response was found in 85.7% (60/70) of the patients and 60.6% (83/137) had CMV viraemia. QuantiFERON-CMV response and detectable CMV DNA were associated with lower CD4 cell count, older age and upper gastrointestinal complaints. During one year of follow-up, the IRR for death among CMV DNA positive patients was 1.5 (P = 0.5). CONCLUSIONS: CMV coinfection was detected among all enrolled patients and CMV viraemia was highly prevalent. Only age and upper gastrointestinal complaints were associated with the patients' CMV status.

INTRODUCTION: Our aim was to determine the reason for consultation and the clinical features of depressive disorders according to the diagnostic and statistical manual (DSM) 4th edition IV R in primary care and to identify if there is an association between sociodemographic characteristics and depressive pattern. MATERIALS AND METHODS: In a cross-sectional study conducted to determinate the prevalence of depressive disorders in primary care, at three urban centers in two cities Salé and Oujda by five physicians, we recruited primary care 396 patients of whom 58 were depressed, among these patients we screened for depressive disorders, their clinical features, the melancholic characteristics and suicidal ideation using the Mini International Neuropsychiatric Interview. RESULTS: Mean age of the 58 depressive patients was 46±15 years. They were predominantly female, inactive and of low socio-economic level. Approximately one-third of the patients were illiterate and single. The symptoms frequently encountered were sadness (63.7%), anhedonia (62%), insomnia (45.7%), anorexia (60.9%), psychomotor retardation (60.9%) and asthenia (73.9%). Somatic symptoms were present 99%, the most common complaint was pain that exhibited 68.6% prevalence. Suicidal ideations were found in 36.2% of these depressive patients. CONCLUSION: The accuracy of the clinical features of patients with depression in primary care will facilitate the detection of these disorders by general practitioners and improve management of depression.
RESUMO
OBJECTIVES: To present the features of human leptospirosis over three time periods (1970-1975; 2000-2005; 2010-2015), to compare the collected data and to determine whether the incidence, seasonal and spatial distribution, prevalence of presumptive infective serogroups and clinical features have changed over the last 50 years. METHODS: Epidemiological and clinical data obtained from patients hospitalised and treated in a well-known endemic focus of leptospirosis, Koprivnica-Krizevci County in Croatia, were analysed. RESULTS: We observed a steady decline in the overall incidence of leptospirosis and a change in the patient age distribution, with the age ratio changing in favour of middle-aged and older patients. Although leptospirosis was most frequently diagnosed in August in all time periods, the number of cases increased in autumn. The most prevalent serogroup during the first and the second time period was Icterohaemorrhagiae, while in the third time period, the serogroup Australis prevailed. We also noted an increase in the number of severe clinical manifestations. CONCLUSIONS: This retrospective research demonstrates a continuous decline in the incidence of human leptospirosis in Croatia. The pattern of disease has changed from predominantly mild clinical forms observed in children to more severe clinical forms observed in middle-aged to older patients, especially those working in agriculture. Additional epidemiological changes included an increase in the number of cases during the autumn months and changes in prevailing serogroups. Statistical analysis revealed a significant relationship between the severity of the clinical picture, patient age and presumed sources of infection.

BACKGROUND: In Belgium, the law of "social defense" stipulates that an accused "which is either in a state of dementia or in a serious state of mental disturbance or mental deficiency, incapable of controlling his actions" can be interned. The establishment of social defense (ESD) in Tournai (Belgium) hosts 350 inmates. OBJECTIVES: In collaboration with the Centre for research in social defense, we organized a systematic assessment of patients interned in ESD. This is the first study evaluating prospectively this population. METHODS: Of the total, 229 patients signed informed consent. Different scales of assessment (MINI, WAIS-III, SCID II) were used. Descriptive analyzes were applied (SPSS version 12). RESULTS: We show that 48.8 % of our participants had committed a sexual offense (rape or attempted rape, indecent assault, public outrage or mixed). The average intelligence quotient is 71.4. According to the MINI, 33.2 % of participants showed no psychiatric disorder. Among psychiatric disorders, psychotic disorders are the most represented (37.4 %). According to the SCID, personality disorders were absent in 26.8 % of our participants. Most of the axis II disorders are represented personality disorders related to cluster B (57.3 %) mainly with antisocial personality disorder (37.9 %). CONCLUSION: These data demonstrate the significant heterogeneity of our sample and the need for the establishment of specific care routes to each subpopulation.

OBJECTIVE: To estimate the independent and combined risks of infant and child mortality associated with maternal smoking and use of solid fuel in sub-Saharan Africa. METHODS: Pooled weighted data on 143 602 under-five children in the most recent demographic and health surveys for 15 sub-Saharan African countries were analysed. The synthetic cohort life table technique and Cox proportional hazard models were employed to investigate the effect of maternal smoking and solid cooking fuel on infant (age 0-11 months) and child (age 12-59 months) mortality. Socio-economic and other confounding variables were included as controls. RESULTS: The distribution of the main explanatory variable in households was as follows: smoking + solid fuel - 4.6%; smoking + non-solid fuel - 0.22%; no smoking + solid fuel - 86.9%; and no smoking + non-solid fuel - 8.2%. The highest infant mortality rate was recorded among children exposed to maternal smoking + solid fuel (72 per 1000 live births); the child mortality rate was estimated to be 54 per 1000 for this group. In full multivariate models, the risk of infant death was 71% higher among those exposed to maternal smoking + solid fuel (HR = 1.71, CI: 1.29-2.28). For ages 12 to 59 months, the risk of death was 99% higher (HR = 1.99, CI: 1.28-3.08). CONCLUSIONS: Combined exposures to cigarette smoke and solid fuel increase the risks of infant and child mortality. Mothers of under-five children need to be educated about the danger of smoking while innovative approaches are needed to reduce the mortality risks associated with solid cooking fuel.

On the basis of a pot experiment under lead (Pb) stress, we investigated the effects of an arbuscular mycorrhizal (AM) fungus (Funneliformis mosseae) on the growth and Pb uptake of Sophora viciifolia L., and explored the Pb localization in AM roots using transmission electron microscopy (TEM) and energy dispersive X-ray spectroscopy (EDS). The results showed that high Pb levels (500 and 1000 µg/g) inhibited the growth of S. viciifolia seedlings. Compared with the noninoculation treatment, F. mosseae inoculation decreased the Pb concentrations above- and belowground by 61.0% and 15.2%, when exposed to Pb at a concentration of 1000 µg/g. The root length, fork number, tip number, surface area, and volume of mycorrhizal S. viciifolia were higher than those of the corresponding nonmycorrhizal plants. These parameters of mycorrhizal plants increased by 220%, 219%, 157%, 225%, and 278% when plants were exposed to Pb at 1000 µg/g compared with nonmycorrhizal plants. The ratio of root length with diameters between 0-0.2 mm to the total root length significantly increased under Pb stress, and F. mosseae inoculation significantly reduced the ratio. Under Pb stress, F. mosseae increased the ratios of root length with 0.61-0.8 and 0.81-1.0 mm diameters to the total root length, indicating that F. mosseae tended to thicken the roots of S. viciifolia under Pb additions. The combined results of TEM and EDS indicated that Pb deposited in not only plant cells but also the cell walls and vacuoles of the AM fungal intracellular hyphae, thus revealing the subcellular-level mechanism of AM fungi in alleviating the Pb toxicity to the host plant.

INTRODUCTION: Pulmonary pneumocystis causes interstitial lung disease, particularly in patients with solid cancers. The aim of this study is to clarify its incidence, which remains poorly understood, and to identify patients at risk and prognostic factors. METHODS: Data on patients with solid tumors and pulmonary pneumocystis were retrospectively collected from January 1, 2014 to December 31, 2019 in two hospitals in Rennes. Incidence was estimated via the Poisson model. Survival data were estimated using Kaplan-Meier method and Log-rank test. A multivariate Cox model was performed to identify risk factors for death. RESULTS: The incidences of pulmonary pneumocystis in metastatic cancer patients receiving parenteral systemic therapy are 198 and 349 cases per 100,000 patients per year in these two centers, respectively. Most patients were being treated with corticosteroids and chemotherapy at the time of pulmonary pneumocystis. The mortality rate for patients with pulmonary pneumocystis is 38%. Median overall survival was 2,7 months. Risk factors for death are corticotherapy greater than 20mg, prednisone equivalent, daily and chemotherapy. DISCUSSION: Pulmonary pneumocystis pneumonia is rare but not exceptional and has a poor prognosis in solid oncology. It frequently occurs in patients treated with long-term corticosteroids. Oncologists need to be better informed to discuss prophylaxis whenever corticosteroids are prescribed for several weeks.
RESUMO
OBJECTIVES: International Classification of Diseases (ICD) codes are commonly used to identify cases of diabetic ketoacidosis (DKA) in health services research, but they have not been validated. Our aim in this study was to assess the accuracy of ICD, 10th revision (ICD-10) diagnosis codes for DKA. METHODS: We conducted a multicentre, cross-sectional study using data from 5 hospitals in Ontario, Canada. Each hospitalization event has a single most responsible diagnosis code. We identified all hospitalizations assigned diagnosis codes for DKA. A true case of DKA was defined using laboratory values (serum bicarbonate ≤18 mmol/L, arterial pH ≤7.3, anion gap ≥14 mEq/L, and presence of ketones in urine or blood). Chart review was conducted to validate DKA if laboratory values were missing or the diagnosis of DKA was unclear. Outcome measures included positive predictive value (PPV), negative predictive value (NPV), sensitivity, and specificity of ICD-10 codes in patients with laboratory-defined DKA. RESULTS: We identified 316,517 hospitalizations. Among these, 312,948 did not have an ICD-10 diagnosis code for DKA and 3,569 had an ICD-10 diagnosis code for DKA. Using a combination of laboratory and chart review, we identified that the overall PPV was 67.0%, the NPV was 99.7%, specificity was 99.6%, and sensitivity was 74.9%. When we restricted our analysis to hospitalizations in which DKA was the most responsible discharge diagnosis (n=3,374 [94.5%]), the test characteristics were PPV 69.8%, NPV 99.7%, specificity 99.7%, and sensitivity 71.9%. CONCLUSION: ICD-10 codes can identify patients with DKA among those admitted to general internal medicine.

THE AIM OF THE STUDY: This study reports a series of 290 cases of hydatidosis confirmed by the surgery and/or the imagery with a positive immuno-diagnosis collected between 1st January 2006 and 31 March 2011 at parasitology-mycology laboratory of hospital university center of Mustapha of Algiers. Our aim is to specify, through the listed cases, the epidemiological aspects of this affection and compared with those obtained in two previous Algerian epidemiological investigations carried out, between 1963-1964 and 1966-1975. PATIENTS AND METHODS: It is a retrospective (2006-2008) and prospective (2008-2011) study. The parasitological diagnosis was carried out by the direct macroscopic and/or microscopic identification of the parasite and indirect diagnosis based on four techniques: passive hemagglutination, Elisa IgG "Echinococcus granulosus", Western Blot IgG "Echinococcus" and electrophoresis. RESULTS: The study shows that this affection is still prerogative of the young adult. It bring out also in this study that the child of school age (ten years), in particular the boy, pays a heavy tribute. At the child, the preferential pulmonary seat of the hydatic disease is not devoid of risk. At adult, this parasitic disease mainly affect the active woman. CONCLUSION: Generally, the epidemiological and clinical characteristics join the endemic countries data and confirmed the row of our country among them. The transmission seems as strong as in the past, in spite of a much better social educational level.

DSM-IV mixed states have become the mixed mania and mixed depression in the new DSM-5. One noticeable point is the introduction of nine cations, among which the "with mixed features" specification. These non exclusive specifications may contribute to a more precise identification of mixed clinical pictures, and therefore to offer a more efficient therapeutic answer. Different dimensional approaches are widely documented. They allow the isolation of a mixed factor which is clinically associated with two other specifications: anxious distress and psychotic features. These severity markers may encourage clinicians to be alert about the risk of misdiagnosis, and cautious in the management of these clinical situations.

INTRODUCTION: More and more French cancer patients are offered by their physicians having their genetic characteristics analyzed (diagnosis, adaptation of treatment plans, etc.). In oncology, considering the development of personalized medicine, these analyses are commonplace. Analyses of germline (hereditary) genetic characteristics require information from patients who must sign an informed consent (article 16.10 of the Civil Code and articles L. 1131-3 and L. 1122-1-1 of the Public Health Code). However, prescribing physicians are rarely geneticists and have little training in genetics. Patients report that few are able to answer their questions and often sign a consent that is not truly informed. METHODS: To identify the genetic knowledge and training needs of prescribers, we conducted an online survey of physicians prescribing genetic testing in oncology between January and March 2020. The survey consisted of 17 closed questions and 3 open questions. RESULTS: We obtained 35 usable questionnaires which show that 50% of the prescribing physicians questioned lack knowledge of genetics, but do not express a need for training. They were interested in the provision of a digital teaching aid for patients. DISCUSSION: We have therefore made a film for patients, available in free access, which aims to shed light on the analysis of genetic characteristics. The film helps physicians to explain the offered analyses and their consequences (https://youtu.be/5lWUSsteavs).
RESUMO
The objective of this study was to validate an automated self-administered 24-hour dietary recall web application (R24W) against recovery biomarkers for sodium, potassium and protein intakes and to identify individual characteristics associated with misreporting in a sample of 61 men and 69 women aged 20-65 years from Québec City, Canada. Each participant completed 3 dietary recalls using the R24W, provided two 24-hour urinary samples and completed questionnaires to document psychosocial factors. Mean reported intakes were 2.2%, 2.1% and 5.0% lower than the urinary reference values, respectively, for sodium, potassium and proteins (significant difference for proteins only (p = 0.04)). Deattenuated correlations between the self-reported intake and biomarkers were significant for sodium (r = 0.48), potassium (r = 0.56) and proteins (r = 0.68). Cross-classification showed that 39.7% (sodium), 42.9% (potassium) and 42.1% (proteins) of participants were ranked into the same quartile with both methods and only 4.8% (sodium), 3.2% (potassium) and 0.8% (proteins) were ranked in opposite quartiles. Lower body esteem related to appearance was associated with sodium underreporting in women (r = 0.33, p = 0.006). No other individual factor was found to be associated with misreporting. These results suggest that the R24W has a good validity for the assessment of sodium, potassium and protein intakes in a sample of French-speaking adults. Novelty: The validity of an automated self-administered 24-hour dietary recall web application named the R24W was tested using urinary biomarkers. According to 7 criteria, the R24W was found to have a good validity to assess self-reported intakes of sodium, potassium and proteins.

OBJECTIVE: to describe the epidemio-clinical and evolutionary characteristics of severe eclampsia in the intensive care unit. PATIENTS AND METHOD: retrospective descriptive and analytical study from 2014 to 2018 carried out in intensive care of the Cocody University Hospital including severe eclamptics with organic failure. RESULTS: The average prevalence was 12.1%. The mean age was 24.3±6.7 years. Primigravidae and primiparae were the most exposed. The mean time to admission was 16.9±16.7 hours. The mean Glasgow score at admission was 10.2±2.2 and 17.5% of patients had severe hypertension. Associated complications were dominated by the HELLP syndrom (33.6%). Specific treatment was magnesium sulphate (82.1%). Treatment non-compliance was 31.6%. The average length of hospitalization was 3.8±4.3 days. Mortality was 15.3%. Age = 25 years, primigravida, Glasgow score < 8, associated complications, non-use of MgSO4 and therapeutic non-observance were statistically significantly associated with maternal death. CONCLUSION: Eclampsia remains a critical issue for maternal health. Prevention relies on early management and awareness during antenatal consultations.
OBJECTIF: décrire les caractéristiques épidémio-cliniques et évolutives de l'éclampsie grave en réanimation. PATIENTS ET MÉTHODE: étude rétrospective descriptive et analytique de 2014 à 2018 effectuée en réanimation au CHU de Cocody incluant les éclamptiques graves avec une défaillance vitale. RÉSULTATS: La prévalence moyenne était de 12,1%. L'âge moyen était de 24,3±6,7 ans. Les primigestes et les primipares étaient les plus exposées. Le délai d'admission moyen était de 16,9±16,7 heures. A l'admission, le score de Glasgow moyen était de 10,2±2,2 et 17,5% des patientes avaient une HTA sévère. Les complications associées étaient dominées par le HELLP syndrome (33,6%). Le traitement spécifique était le sulfate de magnésium (82,1%). L'inobservance du traitement était de 31,6%. La durée moyenne d'hospitalisation était de 3,8±4,3 jours. La mortalité était de 15,3 %. L'âge = 25 ans, la primigestité, le délai d'évacuation = 6h, le score de Glasgow < 8, les complications associées, la non-utilisation du MgSO4 et l'inobservance thérapeutique étaient statistiquement associés au décès maternel. CONCLUSION: l'éclampsie demeure un problème crucial pour la santé maternelle. La prévention repose sur la prise en charge précoce et la sensibilisation au cours des consultations prénatales.
RESUMO
BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has led to a public health crisis. Only limited data are available on the characteristics and outcomes of patients hospitalized for COVID-19 in France. AIMS: To investigate the characteristics, cardiovascular complications and outcomes of patients hospitalized for COVID-19 in France. METHODS: The Critical COVID-19 France (CCF) study is a French nationwide study including all consecutive adults with a diagnosis of severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2) infection hospitalized in 24 centres between 26 February and 20 April 2020. Patients admitted directly to intensive care were excluded. Clinical, biological and imaging parameters were systematically collected at hospital admission. The primary outcome was in-hospital death. RESULTS: Of 2878 patients included (mean±SD age 66.6±17.0 years, 57.8% men), 360 (12.5%) died in the hospital setting, of which 7 (20.7%) were transferred to intensive care before death. The majority of patients had at least one (72.6%) or two (41.6%) cardiovascular risk factors, mostly hypertension (50.8%), obesity (30.3%), dyslipidaemia (28.0%) and diabetes (23.7%). In multivariable analysis, older age (hazard ratio [HR] 1.05, 95% confidence interval [CI] 1.03-1.06; P<0.001), male sex (HR 1.69, 95% CI 1.11-2.57; P=0.01), diabetes (HR 1.72, 95% CI 1.12-2.63; P=0.01), chronic kidney failure (HR 1.57, 95% CI 1.02-2.41; P=0.04), elevated troponin (HR 1.66, 95% CI 1.11-2.49; P=0.01), elevated B-type natriuretic peptide or N-terminal pro-B-type natriuretic peptide (HR 1.69, 95% CI 1.0004-2.86; P=0.049) and quick Sequential Organ Failure Assessment score ≥2 (HR 1.71, 95% CI 1.12-2.60; P=0.01) were independently associated with in-hospital death. CONCLUSIONS: In this large nationwide cohort of patients hospitalized for COVID-19 in France, cardiovascular comorbidities and risk factors were associated with a substantial morbi-mortality burden.
