Growth performance, breast yield, gastrointestinal ecology and plasma biochemical profile in broiler chickens fed multiple doses of a blend of red, brown and green seaweeds.

1. A total of 864 d old (male) Ross × Ross 708 broiler chicks were allocated to 48 floor pens (12 pens/treatment and 18 birds/pen) to investigate dose-response of a blend of seaweeds (SB) on growth performance, breast yield, jejunal histomorphology, microbial metabolites and community and plasma biochemical profile. 2. A maize-soybean meal diet was formulated with 0, 5, 10 or 20 g/kg of SB. Diets were formulated for a three-phase feeding programme (starter: d 0-10, grower: d 11-24, and finisher: d 25-42) and met or exceeded Aviagen nutrient specifications. Diets were allocated to pens (n = 12) balanced for body weight (BW). Birds had free access to feed and water, BW and feed intake (FI) were monitored by phase. One bird per pen was randomly selected on d 42, bled for plasma, and samples for intestinal tissue and caecal digesta were taken. Microbial DNA was extracted and submitted for microbial community profile using the Illumina Miseq® platform. 3. In the starter phase, SB linearly (P ≤ 0.01) improved BW, body weight gain (BWG), and FCR. However, the improvement was quadratic, such that there was no further improvement beyond 5 g/kg SB inclusion. Growth performance response to SB in the grower phase was similar to the starter phase, with the exception of FCR (P > 0.05). Overall, from d 0-42, a linear and quadratic (P < 0.01) response was observed for final BW (d 42), whereby birds fed 5, 10 and 20 g/kg SB were heavier than control by 166, 183 and 180 g, respectively. A quadratic (P = 0.03) effect was observed for breast yield in response to SB. There was a quadratic reduction (P < 0.05) in gamma-glutamyl transferase (GGT) and a linear increase in glutamate dehydrogenase (GDH) in response to SB. Supplemental SB linearly reduced (P ≤ 0.04) the relative abundance of phylum Bacteroidetes and Proteobacteria, and increased the abundance of phylum Firmicutes (linearly; P = 0.02) and Actinobacteria (quadratically; P = 0.03). 4. The data indicated that the optimal inclusion for SB was between 5 and 10 g/kg for improved growth performance and breast yield. However, increased abundance of Firmicutes and actinobacteria in the caecal digesta suggested that the higher doses enhanced prebiotic effects of seaweed components.

Impact of video games on plasticity of the hippocampus.

The hippocampus is critical to healthy cognition, yet results in the current study show that action video game players have reduced grey matter within the hippocampus. A subsequent randomised longitudinal training experiment demonstrated that first-person shooting games reduce grey matter within the hippocampus in participants using non-spatial memory strategies. Conversely, participants who use hippocampus-dependent spatial strategies showed increased grey matter in the hippocampus after training. A control group that trained on 3D-platform games displayed growth in either the hippocampus or the functionally connected entorhinal cortex. A third study replicated the effect of action video game training on grey matter in the hippocampus. These results show that video games can be beneficial or detrimental to the hippocampal system depending on the navigation strategy that a person employs and the genre of the game.

Prevalence of methicillin-resistant Staphylococcus aureus in Canadian commercial pork processing plants.

AIMS: This study investigated the prevalence of Methicillin-resistant Staphylococcus aureus (MRSA), their spa-types, and antimicrobial resistance profiles at various steps during commercial pork production from three plants designated as A, B and C. METHODS AND RESULTS: Over a period of 1 year 2640 samples from three commercial pork plants were obtained on a rotating basis. Sample sources were: nasal swabs after bleeding (NSAB), nasal swab after scalding (NSASs, plant C) or skinning (NSASk, plants A, B), carcass swabs after pasteurization (CSAP, plant C) or washing (CSAW, plants A, B) and retail pork (RP). Overall MRSA prevalence at each sampling point in the pork plants after adjusting for clustering was: 61·93, 28·38 7·58 and 1·21% for NSAB, NSASc/Sk, CSAP/CSAW and RP respectively. The majority of MRSA isolates from the three pork plants belonged to livestock-associated MRSA spa-types t034 and t011 (3·8%; ST398). The mainly human spa-type t002 (15%) was also recovered. All MRSA isolates were resistant to ß-lactam and tetracycline antibiotics. Overall resistance to tigecycline was found in about 10% of MRSA isolates while <3% isolates were resistant to daptomycin, gentamicin, quinupristin/dalfopristin and trimethoprim/sulfamethoxazole. CONCLUSION: A higher prevalence of MRSA in the nasal cavity of incoming pigs was observed at all three plants, but a notable reduction in MRSA along the pork processing steps occurred. SIGNIFICANCE AND IMPACT OF THE STUDY: The highest prevalence of MRSA was found in the nasal cavity of incoming pigs in three commercial pig slaughter and pork processing plants. A reduction in MRSA prevalence occurred along the processing chain, and pork products from these plants showed significantly lower MRSA than the initial steps of slaughter and processing, suggesting a reduction in MRSA during the slaughter process with minimal cross-contamination.

Importance of carbon solubility and wetting properties of nickel nanoparticles for single wall nanotube growth.

Optimized growth of single wall carbon nanotubes requires full knowledge of the actual state of the catalyst nanoparticle and its interface with the tube. Using tight binding based atomistic computer simulations, we calculate carbon adsorption isotherms on nanoparticles of nickel, a typical catalyst, and show that carbon solubility increases for smaller nanoparticles that are either molten or surface molten under experimental conditions. Increasing carbon content favors the dewetting of Ni nanoparticles with respect to sp(2) carbon walls, a necessary property to limit catalyst encapsulation and deactivation. Grand canonical Monte Carlo simulations of the growth of tube embryos show that wetting properties of the nanoparticles, controlled by carbon solubility, are of fundamental importance to enable the growth, shedding new light on the growth mechanisms.

Pathogenic and multidrug-resistant Escherichia fergusonii from broiler chicken.

An Escherichia spp. isolate, ECD-227, was previously identified from the broiler chicken as a phylogenetically divergent and multidrug-resistant Escherichia coli possessing numerous virulence genes. In this study, whole genome sequencing and comparative genome analysis was used to further characterize this isolate. The presence of known and putative antibiotic resistance and virulence open reading frames were determined by comparison to pathogenic (E. coli O157:H7 TW14359, APEC O1:K1:H7, and UPEC UTI89) and nonpathogenic species (E. coli K-12 MG1655 and Escherichia fergusonii ATCC 35469). The assembled genome size of 4.87 Mb was sequenced to 18-fold depth of coverage and predicted to contain 4,376 open reading frames. Phylogenetic analysis of 537 open reading frames present across 110 enteric bacterial species identifies ECD-227 to be E. fergusonii. The genome of ECD-227 contains 5 plasmids showing similarity to known E. coli and Salmonella enterica plasmids. The presence of virulence and antibiotic resistance genes were identified and localized to the chromosome and plasmids. The mutation in gyrA (S83L) involved in fluoroquinolone resistance was identified. The Salmonella-like plasmids harbor antibiotic resistance genes on a class I integron (aadA, qacEΔ-sul1, aac3-VI, and sulI) as well as numerous virulence genes (iucABCD, sitABCD, cib, traT). In addition to the genome analysis, the virulence of ECD-227 was evaluated in a 1-d-old chick model. In the virulence assay, ECD-227 was found to induce 18 to 30% mortality in 1-d-old chicks after 24 h and 48 h of infection, respectively. This study documents an avian multidrug-resistant and virulent E. fergusonii. The existence of several resistance genes to multiple classes of antibiotics indicates that infection caused by ECD-227 would be difficult to treat using antimicrobials currently available for poultry.

Development of a DNA microarray for enterococcal species, virulence, and antibiotic resistance gene determinations among isolates from poultry.

A DNA microarray (Enteroarray) was designed with probes targeting four species-specific taxonomic identifiers to discriminate among 18 different enterococcal species, while other probes were designed to identify 18 virulence factors and 174 antibiotic resistance genes. In total, 262 genes were utilized for rapid species identification of enterococcal isolates, while characterizing their virulence potential through the simultaneous identification of endogenous antibiotic resistance and virulence genes. Enterococcal isolates from broiler chicken farms were initially identified by using the API 20 Strep system, and the results were compared to those obtained with the taxonomic genes atpA, recA, pheS, and ddl represented on our microarray. Among the 171 isolates studied, five different enterococcal species were identified by using the API 20 Strep system: Enterococcus faecium, E. faecalis, E. durans, E. gallinarum, and E. avium. The Enteroarray detected the same species as API 20 Strep, as well as two more: E. casseliflavus and E. hirae. Species comparisons resulted in 15% (27 isolates) disagreement between the two methods among the five API 20 Strep identifiable species and 24% (42 isolates) disagreement when considering the seven Enteroarray identified species. The species specificity of key antibiotic and virulence genes identified by the Enteroarray were consistent with the literature adding further robustness to the redundant taxonomic probe data. Sequencing of the cpn60 gene further confirmed the complete accuracy of the microarray results. The new Enteroarray should prove to be a useful tool to accurately genotype strains of enterococci and assess their virulence potential.

Veterinary pharmaceuticals and antibiotic resistance of Escherichia coli isolates in poultry litter from commercial farms and controlled feeding trials.

Veterinary pharmaceuticals are commonly used in poultry farming to prevent and treat microbial infections as well as to increase feed efficiency, but their use has created public and environmental health concerns. Poultry litter contains antimicrobial residues and resistant bacteria; when applied as fertilizer, the level and effects of these pharmaceuticals and antimicrobial-resistant bacteria in the environment are of concern. The purpose of this study was to investigate poultry litter for veterinary pharmaceuticals and resistance patterns of Escherichia coli. Litter samples were collected from controlled feeding trials and from commercial farms. Feed additives bacitracin, chlortetracycline, monensin, narasin, nicarbazin, penicillin, salinomycin, and virginiamycin, which were present in the feed on commercial farms and added to the feed in the controlled trials, were extracted in methanol and analyzed by liquid chromatography-mass spectrometry techniques. Sixty-nine E. coli were isolated and identified by API 20E. The susceptibility of the isolates to antibiotics was determined using Avian plates and the Sensititer automated system. This study confirmed the presence of antimicrobial residues in broiler litter from controlled environments as well as commercial farms, ranging from 0.07 to 66 mg/L depending on the compound. Concentrations of individual residues were higher in litter from controlled feeding trials than those from commercial farms. All E. coli isolates from commercial farms were multiresistant to at least 7 antibiotics. Resistance to beta-lactam antibiotics (amoxicillin, ceftiofur), tetracyclines, and sulfonamides was the most prevalent. This study concluded that broiler litter is a source of antimicrobial residues and represents a reservoir of multiple antibiotic-resistant E. coli.

Growth performance, meat quality, and gut microflora of broiler chickens fed with cranberry extract.

Cranberry fruit components have been reported to have antimicrobial activities against a variety of pathogenic bacteria and to be beneficial for human health. Studies on their effects are very limited in animals and especially in chickens. This study investigated the effect of feed supplementation with a commercial cranberry fruit extract (CFE) on the performance, breast meat quality, and intestinal integrity of broiler chickens. Twelve hundred male 1-d-old broiler chicks were allocated randomly to CFE treatments at 0, 40, 80, or 160 mg/kg of feed from d 0 to 35. Cloacal and cecal samples were collected weekly to evaluate the influence of treatments on the intestinal population of generic Escherichia coli, Clostridium perfringens, Enterococcus spp., and Lactobacillus spp. At d 35, BW were 1.62, 1.60, 1.61, and 1.64 kg for the control birds and birds fed 40, 80, and 160 mg of CFE/kg of feed, respectively. Feed intake ranged from 2.7 to 2.8 kg and feed efficiency from 1.8 to 1.9 g of feed/g of BW. However, the treatment effects on bird performance were not statistically significant (P > 0.05). The mortality rate tended to be lower (P = 0.09) in birds fed 40 mg of CFE/kg of feed. Feed supplementation with CFE did not significantly alter any broiler meat properties evaluated when compared with the control diet (P > 0.05). At d 28, the populations of Enterococcus spp. in cecal and cloacal samples were significantly lower (P < 0.05) in birds receiving CFE at 160 mg/kg of feed than the other groups. No significant differences were noted between the control and the treatment groups for general health and intestinal integrity (P > 0.05). These findings suggest that more studies are needed to investigate potential beneficial effects of CFE or its derivatives in broiler production.

[Evaluation of the care of the severe acute malnutrition in the service of pediatrics of the CHU Gabriel TOURE, Bamako, Mali]. / Evaluation de la prise en charge de la malnutrition aigue severe dans le service de pediatrie du Centre Hospitalier Universitaire (CHU) Gabriel TOURE, Bamako, Mali.

OBJECTIVE: To study the care of children suffering from severe acute malnutrition with complications at the URENI of the pediatrics of the CHU (University Hospital) Gabriel TOURE. PATIENTS AND METHOD: it was a comprehensive cross-sectional study with a retrospective collection of data on children monitored for the treatment of severe acute malnutrition from January 1st till December 31st, 2014. We, also, conducted a qualitative survey of staff and carers of children under treatment during the survey period. RESULTS: 490 patients were admitted directly to URENI. The 12-23 month age group was predominant (46.5%). The sex ratio was 1.09 in favor of the male sex. The success rate of treatment at the URENI was 51.40%. At the URENAS, the dropout rate was 27.50%. At the URENAM, the dropout rate was 72.70%. Almost all the carers interviewed during the individual interviews and focus groups were satisfied with nutritional care. CONCLUSION: The lack of autonomous hospitalization rooms at the URENI and the inadequacies noticed at the level of performance indicators have to motivate the creation of an URENI answering the standards at the level of the pediatrics of the CHU (University Hospital) Gabriel TOURE.

OBJECTIF: Etudier la prise en charge des enfants souffrant de malnutrition aiguë sévère avec complications au niveau de l'URENI de la Pédiatrie du CHU Gabriel TOURE. PATIENTS ET MÉTHODE: Il s'agissait d'une étude transversale exhaustive avec un recueil rétrospectif des données sur les enfants suivis pour le traitement de la malnutrition aiguë sévère du 1er janvier au 31 décembre 2014. Nous avons, aussi, procédé à une enquête qualitative auprès du personnel et des accompagnants des enfants sous traitement pendant la période de l'enquête. RÉSULTATS: Il y avait 490 patients admis directement à l'URENI . La tranche d'âge de 12-23 mois était prédominante (46,5%). Le sex-ratio était de 1,09 en faveur du sexe masculin. Le taux de succès au traitement à l'URENI était de 51,40%. A l'URENAS, le taux d'abandon était de 27,50%. A l'URENAM, le taux d'abandon était de 72,70%. La quasi-totalité des accompagnantes interviewées, en entretien individuel et en focus groupe, étaient satisfaites de la prise en charge nutritionnelle. CONCLUSION: L'absence de salles d'hospitalisation autonome à l'URENI et les insuffisances constatées au niveau des indicateurs de performance doivent motiver la création d'une URENI répondant aux normes au niveau de la pédiatrie du CHU Gabriel TOURE.

INTRODUCTION: The term polyp refers to any relief formation on the digestive mucosa.The therapeutic endoscopic polypectomy is an effective method to colorectal polyp resection. OBJECTIVE: The maingoal of this work is to study the endoscopic aspects of colo-rectal polyps and to bring our experience on their treatment with endoscopic polypectomy. PATIENTS AND METHOD: Our study was retrospective and descriptive from January 2013 to December 2017 in the endoscopic centers of hepato-gastroenterology department of CHU Gabriel Touré and clinic of "Promenade des angevins". The study concerned in whom polypectomy was performed. RESULTS: A total of 49 patients were included in our study. The main age of our patients was 26.2 2±1.7 years and the sex-ratio was 3.9. The sessile polyps were more frequents with 53.1%. The average size of polyps was 8.7±3.7 mm. The rectum localization was more reported (40.8%). All polyps(100%) were resected in monoblock and we used diathermol cove in 57.1% patients and the cold clamp in 42.9%. Histologically, we had 18 cases of hyperplasia (36.7%), 8 cases of tubulous adenoma (16.3%), 2 cases of tubulo-vilous adenoma (4.1%) and 2 cases of juvenil adenoma (4.1%). One patient was died by perforation five days after the polypectomy. CONCLUSION: The frequency of colorectal polyps is not negligible in our context.Endoscopic colorectal polypectomy is effective therapeutic method for resection of colorectal polyps.

INTRODUCTION: Le terme de polype désigne toute formation en relief sur la muqueuse digestive. La polypectomie endoscopique thérapeutique est la technique de choix pour la résection des polypes colo-rectaux. OBJECTIF: Le but de ce travail est d'étudier les aspects endoscopiquesdes polypes colo-rectaux et d'apporter notre expérience sur leur traitement par la polypectomie endoscopique. PATIENTS ET MÉTHODE: Notre étude descriptive et rétrospective s'est déroulée de janvier 2013 à décembre 2017 à l'unité d'endoscopie du service d'hépato-gastroentérologie du CHU Gabriel Touré et à la clinique promenade des angevins de Bamako.Elle a porté sur les patients adressés pour endoscopie digestive basse.Ont été inclus dans l'étude tous les patients ayant un ou des polypes(nombre < 10) à l'endoscopie et chez qui une polypectomie a pu être réalisée. RÉSULTATS: Au total 49 patients ont été inclus dans notre étude. L'âge moyen de nos patients était de 26,2 ±21,7 ans et lesex-ratio était de 3,9. Les polypes sessiles étaient les plus fréquents soit 53,1%. La taille moyenne des polypesétait de 8,7 ±3,7mm. Le rectum était le siège le plus fréquemment atteint (40,8%). Pour la polypectomie, 100% des polypes ont été reséqués en monobloc et nous avons utilisé l'anse diathermique chez 57,1% des patients et l'anse ou la pince froide chez 42,9%. Sur le plan histologique, nous avons eu 18 cas d'hyperplasie (36,7%), 8 cas d'adénome tubuleux (16,3%), 2 cas d'adénome tubulo-villeux (4,1%) et 2 cas d'adénome juvénile (4,1%). Nous avons enregistré un cas de décès survenu dans un tableau de perforation constatée cinq jours après la polypectomie. CONCLUSION: La fréquence des polypes colorectaux n'est pas négligeable dans notre contexte. La polypectomie endoscopique est un moyen thérapeutique efficace pour le traitement des polypes colo-rectaux.

[Healthcare associated infections in the neurosurgical department of Gabriel Touré teaching Hospital in Bamako]. / Les infections associees aux soins dans le service de neurochirurgie du CHU Gabriel Toure a Bamako.

INTRODUCTION: Healthcare-associated infections or nosocomial infections are a public health problem due to their frequency, severity and economic impact. They cause an increase of the morbidity, the mortality, the hospital stay and the expenses of taking care of the patients. According to the WHO, 7.1 million people are affected each year, of which about 100,000 die. AIM OF STUDY: The aim of this study was to determine the frequency of healthcare-associated infections in the Neurosurgery Department of Gabriel Touré University teaching Hospital and to identify the risk factors associated with these infections. MATERIAL AND METHODS: This was an epidemiological, descriptive, analytic, cross-sectional and prospective study lasting 6 months from May 29 to November 30, 2016. The study focused on patients who stayed more than 48 hours in the Neurosurgical department Gabriel Touré teaching hospital. The collected data focused on the clinical and biological characteristics of the patients during their hospitalization. The maximum size of the sample was 200 patients. A sample was taken for each type of infection. The criteria used for the diagnosis of Healthcare-associated infections were those of the CDC (Center for Disease Control) and the realization of a thick drop in our context. The chi-square test was used for the comparison of qualitative variables and Kruskal Wallis and Anova for quantitative variables. The materiality threshold has been set to a value of p less than 0.05. RESULTS: At the end of our study, we had 34 infected patients out of 200, a rate of 17%. The significant risk factors found in our study were: high age (p = 0.04), ASA class (p = 0.002), pre-surgical shaving (p = 0.02), long duration surgical intervention (p = 0.002) and long hospital stay (p = 0.004). The types of infections associated with the care found were: urinary in 18 (53%) cases, respiratory in 9 (26%) cases, operative site in 6 (18%) cases and 1 (3%) cases of bacteremia. The bacterial spectrum of these infections was dominated by Negative Gram Bacilli, among which Escherichia coli in 11 (32.3%) cases. The clinical course of patients treated for these infections was marked by healing in 31 (91.2%) cases, complications in 2 (5.9%) cases, and death in 1 (2.9%) case. CONCLUSION: The prevalence of Healthcare-associated infections in our department remains high compared to that found in developed countries. This study allowed us to identify the main risk factors associated with these infections. A stricter adherence to the rules of hygiene and prevention of Healthcare-associated infections is needed to reduce this rate.

INTRODUCTION: Les infections associées aux soins (IAS) ou infections nosocomiales constituent un problème de santé publique par leur fréquence, leur gravité et leur retentissement économique. Elles causent une augmentation de la morbidité, la mortalité, le séjour hospitalier et les frais de prise en charge des malades.Selon l'OMS, 7,1 millions de personnes seraient affectées par les IAS chaque année parmi lesquelles environ 100000 meurent de suites de ces ISA. BUT: Le but de cette étude était de déterminer la fréquence des infections associées aux soins dans le service de Neurochirurgie du CHU Gabriel Touré et d'identifier les facteurs de risque associés à ces infections. MATÉRIEL ET MÉTHODES: Il s'agissait d'une étude prospective d'une durée de 6 mois allant du 29 Mai au 30 Novembre 2016. L'étude a porté sur les patients ayant séjourné plus de 48 heures dans le service de Neurochirurgie du CHU Gabriel Touré.Les données collectées ont porté sur les caractéristiques cliniques et biologiques des patients au cours de leur hospitalisation.La taille maximum de l'échantillon a été de 200 malades. Un prélèvement a été fait pour chaque type d'infection.Les critères utilisés pour le diagnostic de l'IAS étaient ceux du CDC (Center for Disease Control) d'Atlanta ainsi que la réalisation d'une goutte épaisse dans notre contexte.Le test de khi2 a été utilisé pour la comparaison des variables qualitatives et Kruskal Wallis et Anova pour les variables quantitatives. Le seuil de signification a été fixé à une valeur de p inférieure à 0,05. RÉSULTATS: Au terme de notre étude nous avons eu 34 patients infectés sur 200, soit un taux de 17%. Les différents facteurs de risque significatifs retrouvés dans notre étude ont été : l'âge élevé (p=0,04), la classe ASA (p=0,002), le rasage pré-chirurgical (p=0,02), la longue durée de l'intervention chirurgicale (p=0,002) ainsi que la longue durée d'hospitalisation (p=0,004). Les types d'infections associées aux soins retrouvés ont été : urinaires dans 18 (53 %) cas, respiratoires dans 9 (26%) cas, site opératoire dans 6 (18%) cas et 1 (3%) cas de bactériémie. Le spectre bactérien de ces infections était dominé par les Bacilles Gram Négatifs parmi lesquels l'Escherichia coli dans 11 (32,3%) cas.L'évolution clinique des patients traités pour ces infections a été marquée par la guérison dans 31 (91,2%) cas, les complications dans 2 (5,9%) cas et le décès dans 1(2,9%) cas. CONCLUSION: La prévalence des infections associées aux soins dans notre service reste élevée par rapport à celle retrouvée dans les pays développés. Cette étude nous a permis d'identifier les principaux facteurs de risque associés à ces infections. Une observance plus stricte des règles d'hygiène et de prévention des IAS s'impose pour faire baisser ce taux.

Genotype comparison of sorbitol-negative Escherichia coli isolates from healthy broiler chickens from different commercial farms.

Hybridization on arrays was used to assess the presence of virulence-associated genes and to determine the relatedness of 32 non-O157 sorbitol-negative Escherichia coli isolates from healthy broiler chickens. These isolates were from commercial farms that used feed supplemented with different antimicrobial agents (virginiamycin, bacitracin, salinomycin, narasin, nicarbazin, or diclazuril). For each isolate, fluorescent probes were made from genomic DNA and were hybridized on DNA arrays composed of genes associated with general functions, virulence, iron uptake systems, and DNA repair genes (e.g., mut genes). Hybridization on arrays results showed that isolates from the same farm tended to be clustered but actually represented 18 genetically distinct groups of isolates. Results revealed that some isolates showed similarity to human uropathogenic E. coli or avian pathogenic E. coli. Four avian pathogenic E. coli-like isolates were detected. Another isolate possessed the intimin gene (eaeA) and typical genes of the type 3 secretion system associated with enteropathogenic E. coli and enterohemorrhagic E. coli strains. Genes from a second system (secondary type 3 secretion system) homologous to that found in Salmonella Typhimurium were detected in many isolates. Several of the studied isolates also possessed the aerobactin, salmochelin, and yersiniabactin genes involved in iron acquisition in pathogenic bacteria. Our results clearly suggest that commensal E. coli isolates from chickens are reservoirs of virulence-associated genes and may represent colibacillosis and zoonotic risks.
