Acquisition and transmission of Grapevine fanleaf virus (GFLV) by Xiphinema index and Xiphinema italiae (Longidoridae).

Grapevine fanleaf virus (GFLV) is one of the most severe virus diseases of grapevines, causing fanleaf degeneration that is transmitted by Xiphinema index. This paper aims to isolate Xiphinema species from Tunisian vineyard soil samples and assess their ability to acquire and transmit GFLV under natural and controlled conditions. Based on morphological and morphometric analyses, Tunisian dagger nematodes were identified as X. index and Xiphinema italiae. These results were confirmed with molecular identification tools using species-specific polymerase chain reaction primers. The total RNA of GFLV was extracted from specimens of Xiphinema and amplified based on real-time polymerase chain reaction using virus-specific primers. Our results showed that X. index could acquire and transmit the viral particles of GFLV. This nepovirus was not detected in X. italiae, under natural conditions; however, under controlled conditions, this nematode was able to successfully acquire and transmit the viral particles of GFLV.

Particularités du cancer du larynx chez le sujet jeune / Epidemiological and clinical predictive factors of success in septoplasty: Study of 250 patients

Discuter à travers une étude descriptive ainsi qu'une revue de la littérature, les particularités cliniques, démographiques et pronostiques des patients de moins de 45 ans, ayant un cancer du larynx. Materiels et Methodes: Il s'agit d'une étude rétrospective descriptive portant sur des patients atteints d'un cancer du larynx, âgés de moins de 45 ans suivis dans le service d'ORL et de chirurgie cervico-faciale du CHU Habib Bourguiba Sfax durant la période s'étendant de 1989 à 2018. Resultats: Nous avons trouvé 31 patients avec une prédominance masculine. Un cancer dans la famille a été trouvé dans 16,12% des cas sans corrélation statistique avec le stade avancé de la maladie. Une importante intoxication tabagique a été trouvée (96%). Trois patients avaient une laryngite chronique et un patient une papillomatose laryngée avec des lésions de dysplasie. Les motifs de consultation étaient dominés par la dysphonie (87%). La maladie a été classée en stades avancés dans 70% des cas. Le traitement chirurgical était préconisé chez 87% des patients et la préservation fonctionnelle chez 38,7%. Le taux de survie globale et sans maladie étaient respectivement, à un an de 96% et 84%, à 3 ans de 87% et 76%, et à 5 ans de 77% et 75% Conclusion: Notre travail n'a pas permis de retenir de différence en termes de données cliniques, de l'évolution de la maladie, de l'algorithme thérapeutique ni du pronostic entre les jeunes patients et les plus âgés

Effet de la prémédication par des corticoïdes systémiques sur la chirurgie endonasale de la polypose naso-sinusienne / Effect of premedication with systemic corticosteroids on endonasal surgery for naso-sinus polyposis

Déterminer si une cure préopératoire de corticoïdes systémiques réduirait le saignement au cours de la chirurgie endonasale de la polypose naso-sinusienne (PNS) et améliorerait la visualisation du champ opératoire. Méthodes: Étude prospective randomisée incluant des adultes (>18 ans) atteints de PNS primitive résistante au traitement médical et qui vont bénéficier d'une chirurgie endoscopique endonasale. Ces patients sont randomisés en deux groupes: un groupe préparé par des comprimés de prednisolone 20mg, à la posologie de 0.5mg/Kg/j pendant 7 jours avant la chirurgie et un groupe non préparé. Les critères d'évaluation sont: la perte sanguine avec la comparaison des hémoglobines (Hb) pré et postopératoires, le temps opératoire et la visibilité du champ opératoire évaluée par le chirurgien selon le score de Boezaart. Résultats: Nous avons inclus 32 patients. Dix-sept patients dans le groupe non préparé et 15 patients dans le groupe préparé. Les deux groupes étaient comparables sur le plan épidémiologique, clinique et paraclinique (p>0,05). La perte sanguine moyenne était plus importante dans le groupe non préparé (700±487 ml versus 500±480 ml) mais sans différence significative (p=0,38). La différence était statistiquement non significative (p=0,24) entre les 2 groupes pour l'Hb postopératoire et pour la différence d'Hb préopératoire - Hb post opératoire. Le temps opératoire était plus court dans le groupe préparé (80±24 min versus 90±64 min) sans différence statistiquement significative (p=0,11). Le score de Boezaart était comparable (médiane=3) (p=0,29). Conclusion: Cet essai clinique n'a pas démontré que l'administration d'une cure préopératoire de corticothérapie orale peut réduire considérablement la perte de sang au cours de la chirurgie de la PNS et améliorer la visualisation du champ opératoire

Smell disorders evolution after chronic rhinosinusitis with polyps surgery

The effects of chronic rhino sinusitis with polyps (CRSWP) surgery on smell symptoms have not been sufficiently studied. The aim of this study was to evaluate the impact of CRSWP surgery on smell symptoms over short and long-term follow-up and to identify the factors that might influence their evolution. Patients and methods: This was a retrospective study about 184 patients operated endoscopically for CRSWP. In post operative period, long-term local steroids were prescribed systematically. The sense of smell was evaluated preand post-operatively according to a subjective score (1: good smell, 2: hyposmia, 3: anosmia). Some factors, related to the patient, the CRSWP and the treatment, were tested in order to identify predictors of smell outcome after surgery.. Results: Before surgery, the anosmia and the hyposmia were noted in 90.8% and in 8.7% of cases, respectively. At six months after surgery, the improvement of olfactory score was significant: 84% of patient had the score 1 compared with 0.5% preoperatively (p < 0.0001). This improvement was maintained during the 2 first years and decreased significantly at 3 years, although an average delay of polyps recurrence was 23.4 months. Among the factors studied in our series, only the observance of postoperative corticosteroids was retained as a predictor of smell recovery after surgery (p = 0,011). Conclusion: CRSWP surgery can significantly improve the smell sense, especially during the two first years. This effect can be sustainable if good post operative compliance for local corticosteroid are achieved.

[Intracorneal ring segments in keratoconus management]. / Les anneaux intra-cornéens dans la prise en charge du kératocône.

Intracorneal ring segments (ICRS), used in the management of keratoconus since the 2000s, have enjoyed significant technological development. Various types of ICRS exist, whose arc length, thickness, and diameter can be chosen according to the desired effect on the spherical equivalent, keratometry and asphericity. Individualized implantation strategies, based on each patient's topographic and tomographic pattern, are constantly evolving. The surgical procedure is standardized, and complications remain very rare. Combined procedures (corneal collagen cross-linking and refractive photokeratectomy±topo-guided, phakic and pseudophakic intraocular lenses) are increasingly used and require a good knowledge of the effect of ICRS alone on the keratoconic cornea. The objective of this review is to summarize clinical practices used in the visual rehabilitation of keratoconic patients using the ICRS+- combined procedures.

[Ductal carcinomas of the parotid gland]. / Les carcinomes canalaires de la parotide.

PURPOSE: To describe the clinical, therapeutic and prognostic features of ductal carcinomas of the parotid gland. MATERIAL AND METHODS: Five patients with ductal carcinoma of the parotid gland (primary and secondary carcinoma) treated, between 2007 and 2019, in our ENT department, were reviewed. RESULTS: Four men and one woman were included. The mean age was 61,4 years. One patient had a history of an invasive ductal carcinoma of the breast. Four patients consulted for swelling in the parotid region. One patient referred to our department for dysfunction of facial nerve. Skin invasion was found in one case. Four patients underwent total parotidectomy with sacrifice of the facial nerve (three cases). One patient underwent extended parotidectomy involving the skin. An ipsilateral selective neck dissection was performed in four cases. One patient had a parotid gland biopsy. Ductal carcinoma was primary in four cases and metastatic from breast origin in one case. Four patients were treated with postoperative radiotherapy. Remission was obtained in three cases. One patient had a local and meningeal recurrence. The patient with metastatic carcinoma had pulmonary, bone, hepatic and brain progression. CONCLUSION: Ductal carcinoma is a rare and aggressive tumor of the parotid gland. It can be primary or secondary. The treatment is based on surgery and radiotherapy. The prognosis is poor.

Purification of arsenic-contaminated water using iron molybdate filters and monitoring of their genotoxic, mutagenic, and cytotoxic effects through bioassays.

Environmental contamination has been a cause of concern worldwide, being aggravated by anthropogenic activities carried out without the correct disposal of toxic products in the various habitats on our planet. In Brazil, mining companies are responsible for the contamination of large river basins with toxic elements from mining activities. Among these elements, arsenic draws attention because it is highly carcinogenic and found in waters in concentrations above those recommended by regulatory agencies. Here, Fe2(MoO4)3 nanoparticles are synthesized and used as a filter medium in water purification systems contaminated with arsenic. The adsorption kinetics of arsenic by Fe2(MoO4)3 nanoparticles is fast, showing pseudo-second-order rate constants of 0.0044, 0.0080, and 0.0106 g mg-1 min-1 for As3+, As5+, and MMA, respectively. The adsorption isotherms are better adjusted with the Langmuir and Redlich-Peterson models, indicating that the arsenic adsorption occurs in monolayers on the Fe2(MoO4)3 surface. The Fe2(MoO4)3 adsorption capacities determined for the As3+, As5+, and MMA species are 16.1, 23.1, and 23.5 mg g-1, respectively. The Fe2(MoO4)3 filter is efficient in purifying arsenic-contaminated water, reducing its initial concentration from 1000 µg L-1 to levels close to zero. Biological tests indicate that Fe2(MoO4)3 nanoparticles and filtered water have no cytotoxic, genotoxic, and mutagenic risks to human life. Those results suggest that the Fe2(MoO4)3 filter can be used as an efficient and safe technology for the purification of water contaminated by arsenic.

Corneal crosslinking in keratoconus management.

Since two decades, corneal crosslinking (CXL) has been proposed as the sole therapeutic option to halt progression of keratoconus or other ectatic diseases. CXL aims at stiffening the cornea using a combination of ultraviolet-A light and a chromophore (vitamin B2, riboflavin), and has been proposed in various indications, from progressive ectatic diseases to corneal infection. Despite being in clinical use for many years, many controversies and discrepancies exist towards CXL procedure and its exact role is still under debate. We report an up-to-date review of the state of the art of CXL and describe the basic principles, the different existing CXL techniques reporting basic and clinical evidence, as well as the new perspectives and the possible future developments of the procedure.

Primary squamous cell carcinoma of the thyroid associated with papillary thyroid carcinoma and Hashimoto's thyroiditis.

INTRODUCTION: We report the first case of squamous cell carcinoma (SCC) of the thyroid gland coexisting with papillary thyroid carcinoma (PTC) and Hashimoto's thyroiditis and discuss various theories concerning the histogenesis of SCC of the thyroid gland and the optimal treatment strategy. CASE REPORT: A 54-year-old woman presented with an anterior neck mass measuring 4cm on clinical examination. Imaging showed a suspicious thyroid nodule invading the trachea. Total thyroidectomy with bilateral central lymph node resection was performed. Histological examination revealed tall cell variant of papillary thyroid carcinoma associated with SCC of the right lobe of the thyroid and Hashimoto's thyroiditis. Immunohistochemistry of the SCC showed positive staining for p53 and Ki67 and negative staining for thyroglobulin. The patient underwent adjuvant radioactive iodine therapy and radiotherapy. With postoperative follow-up of 24 months, the patient was in good health. DISCUSSION: In conclusion, the most probable origin of SCC in this case was malignant transformation from Hashimoto's thyroiditis following a phase of metaplasia. This immunohistological profile is associated with a better prognosis. Optimal treatment consists of extensive surgical resection of tumour tissuefollowed by radiotherapy.

[Primary Sjögren syndrome in a child]. / Syndrome de Goujerot-Sjögren primitif de l'enfant : à propos d'un cas.

Sjögren syndrome is uncommon in children and occurs most often in association with autoimmune diseases (secondary Sjögren syndrome). We describe the clinical and biological features of a 7-year-old girl with primary Sjögren syndrome revealed by recurrent parotiditis. CASE REPORT: A 7-year-old girl was referred for investigation of multiple episodes of parotid swelling since age 4 years, without systemic symptoms. The examination was unremarkable except for enlarged and painless parotid glands. Laboratory investigations and labial salivary gland biopsy revealed Sjögren syndrome without associated disease. Hydroxychloroquine was prescribed with clinical improvement. CONCLUSION: Recurrent parotiditis in children is an uncommon condition. The onset of parotid swelling at 5 years or over deserves screening for disimmune disorders, sarcoidosis, or Sjögren syndrome. Diagnosis of Sjögren syndrome is based on diagnostic criteria.

[Ectopic thymus: A rare cause of neck mass in children]. / Thymus ectopique : une cause rare de tuméfaction cervicale chez le nourrisson.

INTRODUCTION: Ectopic cervical thymus (ECT) is a rare embryological abnormality in children. It can be revealed by a compressive neck mass mistaken for a malignant tumor. Through a new case of ECT, we review the embryopathogenesis, diagnostic difficulties and therapeutic features. CLINICAL OBSERVATION: A 19-month-old girl presented a right cervical mass that quickly increased in size, causing intermittent dyspnea. The physical examination objectified a 6-cm, soft and compressible, painless right cervical tumefaction, extending from the mastoid area to the ipsilateral supraclavicular fossa. The diagnosis suggested based on CT was a cervicomediastinal cystic lymphangioma. The diagnoses discussed based on MRI were a collection of necrotic lymphadenopathy, rhabdomyosarcoma or neurofibroma debris. The mass was surgically excised through a laterocervical incision. A whitish multilobular tissular mass was found, adherent to the neurovascular axis of the neck. Pathological examination concluded in normal ectopic thymus tissue. The postoperative course was uneventful. CONCLUSION: Although ECT is a rare benign anomaly, it should be considered as a possible cause of a neck mass in children. Surgery is the curative treatment. Before surgery, the presence of a mediastinal thymus must be confirmed to avoid the risk of a total thymectomy in children. MRI is helpful in delineating thymic ectopia compared to the mediastinal thymus.

[Perception of glaucoma and therapeutic adherence: A multicenter observational study]. / Perception du glaucome et observance thérapeutique : une étude observationnelle multicentrique.

INTRODUCTION: The purpose of this study was to evaluate medication adherence of glaucoma patients through the "Glaucoma treatment compliance assessment tool (GTCAT)" questionnaire and to correlate the results with clinical parameters. PATIENTS AND METHODS: This multicenter prospective observational study was performed in the Département hospitalo-universitaire (DHU) Sight Restore, Paris, France. All patients had been followed for chronic open angle glaucoma (COAG) for at least 3 years. A French version of the GTCAT questionnaire was administered to patients. The results were correlated with clinical parameters of glaucoma, such as duration of disease, medications used, intraocular pressure (IOP) and mean deviation (MD) of the most recent visual field. RESULTS: Seventy-three patients were included in our study, with 60.9% declaring that they fully adhered to the treatment. There was a correlation between the amount of days missing treatment and difficulties using the eye drops. The main cause of missing the drops was forgetfulness (75%), followed by unavailability of the drop when it was time to take it (37.5%). The impact of glaucoma on quality of life was correlated to the amount of adverse effects of topical medications. The patient's perception of the importance of preserving vision was correlated to the level of confidence in the physician concerning the diagnosis of glaucoma. CONCLUSION: In glaucoma patients, the use of the GTCAT questionnaire confirmed the complex relationship between the patient, the disease and its treatment, and even his or her relationship with the ophthalmologist. These results emphasized the importance of therapeutic education but also the negative role of side effects of the eye drops on treatment adherence in glaucoma patients.

Rhonchopathie chronique : quelle chirurgie pour quels patients ?

Faisant partie de l'arsenal thérapeutique du ronflement, la chirurgie garde encore à ce jour un intérêt majeur. L'efficacité des traitements chirurgicaux est très difficile à évaluer, en raison principalement de l'hétérogénéité des critères d'évaluation rapportés dans la littérature, d'un recul très variable selon les séries, et surtout de la méthodologie des études.Nous avons mené une étude sur 105 patients qui ont été opérés pour le ronflement. Nos résultats ont été rapportés selon différents groupes plus homogènes permettent une comparaison plus fine des résultats. L'analyse univariée a montré un meilleur résultat de la chirurgie chez les ronfleurs simples par rapport aux apnéiques (p=0.03), l'efficacité de la chirurgie en cas d'apnées du sommeil se voyait surtout sur le volume sonore et non sur l'index d'apnées hypopnées. En analyse multivariée, nous avons dégagé le profildes malades chez qui le traitement chirurgical aurait de meilleurs résultats : jeune âge, non obèse, sans rétrognatisme avec un voile long et/ou flasque et avec un index apnées hypopnées< 30

Les perforations pharyngo-oesophagiennes par corps étranger

Introduction : La perforation pharyngo-œsophagienne par ingestion de corps étranger (CE) est une complication rare et grave. De ce fait, sa prise en charge n'est pas standardisée. Le but de ce travail est d'étudier les caractéristiques épidémiologiques et diagnostiques de ces complications et de discuter les modalités thérapeutiques. Patients et méthodes :Sur une période 17 ans (1998 - 2014), nous avons colligé 573 patients ayant ingéré des CE pharyngo-œsophagiens et qui ont bénéficié d'une extraction endoscopique au tube rigide. Onze patients (1,9%) se sont compliqués d'une perforation. Résultats : Il s'agissait de 3 enfants et 8 adultes. Les corps étrangers étaient dominés par les fragments d'os (55% des cas). Les perforations étaient jugées liées aux manœuvres d'extraction dans 54,5% et au CE dans 45,5%. Le diagnostic a été posé dans un délai maximal de 2 jours après extraction. La chirurgie a été réalisée d'emblée dans 2 cas devant la migration extra-viscérale du CE et devant la présence d'une abcédation péri-œsophagienne, respectivement. Le geste opératoire consistait, respectivement, en l'ablation du CE avec suture de l'œsophage et un simple drainage de l'abcès. Dans un autre cas, la chirurgie a été pratiquée en seconde intention après échec du traitement médical et devant l'apparition d'une pleurésie purulente. Le geste opératoire était une suture renforcée par un lambeau intercostal. Un traitement conservateur était instauré dans 8 cas (72,7%).L'évolution était favorable dans 10 cas (soit 90,9%) et fatale dans un seul cas, soit une mortalité de 9,1%. Conclusion : Le pronostic dépend essentiellement de la précocité diagnostique des perforations œsophagiennes par CE. Le traitement conservateur serait suffisant et efficace en dehors d'un syndrome infectieux sévère

["En face" anterior segment optical coherence tomography findings in acute corneal hydrops]. / Apport de l'OCT de segment antérieur « en face ¼ dans le kératocône aigu.

PURPOSE: To study the corneal morphological characteristics of acute hydrops by analyzing anterior segment optical coherence tomography (AS-OCT) "en face" images. PATIENTS AND METHODS: Four patients presenting with acute hydrops were examined at different stages, respectively after 1 day, 1 week, 3 weeks and 6 months. All patients had a complete ophthalmic evaluation including "en face" AS-OCT examination. In vivo confocal microscopy (IVCM) and histological analysis of the cornea obtained after penetrating keratoplasty were also performed in one patient. RESULTS: The "en face" AS-OCT showed that the early edema in acute hydrops corresponded to multiple epithelial microcysts associated with large intra-stromal lacunae. We also observed that, in association with the disappearance of the microcysts and lacunae, "en face" OCT demonstrated subepithelial scars in the form of weakly reflective, fine, interlaced linear opacities. These opacities subsequently increased in thickness resulting in a dense subepithelial network. These findings were consistent with the results of histological and IVCM studies. CONCLUSION: "En face" AS-OCT allows for precise study of the tissue changes occurring in acute corneal hydrops. Besides a better understanding of this rare complication of keratoconus, this new imaging technique may help clinicians to identify the corneal structural changes, which place keratoconus patients at risk of corneal hydrops.

Localisation nasosinusienne des tumeurs plasmocytaires

Introduction : Les tumeurs plasmocytaires representent 3 a 4 des tumeurs des cavites naso-sinusiennes. Elles necessitent un bilan diagnostique specifique et une prise en charge adequate. Nous nous proposons d'etudier les particularites diagnostiques et therapeutiques des plasmocytomes naso-sinusiens. Materiel et methodes : Notre etude est retrospective comportant 5 cas de plasmocytomes naso-sinusiens confirmes histologiquement. Resultats : Il s'agit de 3 hommes et 2 femmes ages de 32 a 77 ans. Le plasmocytome avait une localisation sphenoidale dans un cas; nasale dans 2 cas; ethmoido-nasale dans un cas et naso-maxillaire dans le cas restant. Il s'agissait d'un myelome multiple dans un cas. Trois patients ont eu une radiotherapie. Celle-ci etait associee a une chimiotherapie dans le cas du myelome multiple et a une exerese chirurgicale dans les 2 autres cas La chirurgie a ete seule dans un cas. La chimiotherapie exclusive a ete proposee dans un cas de plasmocytome localement avance mais le patient a ete perdu de vue. Pour les patients suivis; une seule recidive a ete notee a 18 mois. Conclusion : La presentation clinique des plasmocytomes nasosinusiens est aspecifique. Le diagnostic est confirme par l'histologie. Le pronostic est domine par la presence ou non d'un myelome multiple et par la taille tumorale. Un suivi prolonge est necessaire

Lymphoma presenting as a peritonsillar abscess.

INTRODUCTION: Peritonsillar abscess is generally seen as a complication of acute tonsillitis in young subjects. It may, however, in rare cases reveal a malignant tumor of the tonsil: most often squamous cell carcinoma or, more rarely, lymphoma. We report a rare case of tonsillar lymphoma revealed by a peritonsillar abscess. CASE REPORT: A 66-year-old woman, without history of recurrent tonsillitis, was admitted for right peritonsillar abscess with fever. She underwent incision-drainage of the abscess with 10 days' intravenous antibiotics. As tonsillar hypertrophy persisted, tonsillectomy was performed; histology with immunohistochemical examination found tonsillar lymphoma. DISCUSSION/CONCLUSION: Possible tumoral etiology should be considered in any peritonsillar abscess occurring in an atypical subject. Acute-stage tonsillectomy enables early diagnosis.

[Management of traumatic aortic rupture. About 37 cases]. / Prise en charge des ruptures de l'isthme aortique post-traumatiques. À propos de 37 cas.

OBJECTIVES: The aim of this study was to review our experience in the management of traumatic rupture of the aortic isthmus, to evaluate the results of surgery and endovascular exclusion and to develop an adequate therapeutic strategy based on the existence and severity of associated injuries. MATERIAL: A series of 37 patients presenting posttraumatic aortic rupture associated with other severe lesions was collected from 2000 to 2012. There were 33 males and four females, mean age 38 years. In this series, 25 patients underwent surgical treatment and 12 endovascular exclusion. RESULTS: Six patients died during or after surgery. Overall mortality was 16% (24% in the surgery group). The postoperative period was uneventful in all patients treated with the endovascular procedure. Postoperative computed tomography controls at one week, 1 month and 12 months showed good positioning of the stent without endoleakage. CONCLUSION: Traumatic aortic rupture is often the result of a severe high-energy chest trauma. Other serious injuries are often associated. Results of immediate surgical repair are associated with high morbidity and mortality. The advent of endovascular treatment has revolutionized the treatment of traumatic aortic rupture, especially in patients with a high surgical risk.

The use of N-terminal pro-brain natriuretic peptide as a predictor of atrial fibrillation after cardiac surgery.

AIM: Atrial fibrillation (AF) is the most common arrhythmia after cardiac surgery with cardiopulmonary bypass (CPB). The value of Nt-pro BNP in predicting AF complicating cardiac surgery is not well studied. Our objective is to determine its predictive role in the occurrence of this complication after heart surgery with cardiopulmonary bypass. METHODS: It is a prospective observational study including patients proposed for scheduled cardiac surgery with normo-thermal CPB. We performed blood samples for each patient: the first one immediately after the induction of anesthesia and before CPB. The following samples were made at the end of the CBP (H0), 4 hours later (H4) and every day during the first four days (H24, H48, H72 and H96). NT-proBNP and cTnI were measured in each sample. The postoperative AF was defined as any episode of AF documented of a period not less than 15 min recorded in the first 3 days post operative. RESULTS: The most common cardiovascular complication was the AF (17.5%). Rates of Nt-proBNP were significantly increased in patients who developed this complication. The ROC analysis of NT-proBNP at different times studied for the prediction of AF showed that assays at the end of the CPB and those of the 4th postoperative hour (H4) had the best area under the curve (AUC). A threshold value of 353.5 mg/mL of Nt-proBNP at the end of the CPB has a sensitivity of 71% and a specificity of 84% for the prediction of the AF and an AUC of 0.711. The threshold value (307.5 mg/mL) of Nt-proBNP measured at H4 has the same sensitivity but with a lower specificity (74%) and AUC=0.709. DISCUSSION AND CONCLUSION: An early Nt pro BNP at H0 or H4, respectively, and with thresholds of 353 and 307 pg/mL could predict the occurrence of the AF. In this case, a primary prevention could be envisaged.
