RESUMO

OBJECTIVES: Workplace violence of any type is influenced by multiple factors and leads to physiological, psychological, social, and organizational change. Emergency and other urgent care settings have assault rates up to 5-fold higher than other health care settings. This study aimed to analyze the consequences of physical and nonphysical violence on health care and support personnel in hospital emergency departments. MATERIAL AND METHODS: Cross-sectional descriptive analysis of responses to a 121-item survey of 584 health care and support workers in 12 Spanish hospital emergency departments. We analyzed the magnitude of the problem with a two-step self-clustering method and then assessed the associations between variables and workplace violence. RESULTS: Two groups were identified. The first consisted of 298 cases with high mean (SD) scores for nonphysical assaults (51.5 [7.9]) and low scores for physical violence (4.8 [2.9]). The second group consisted of 285 cases with intermediate scores for nonphysical assaults (27.1 [8.4]) and low scores for physical violence (3.4 [1.3]). CONCLUSION: Emergency departments have incidents of nonphysical workplace violence more often than physical violence. Emergency personnel with high exposure to workplace violence, particularly nonphysical assaults, experience physiological, psychosocial, and organizational changes.


OBJETIVO: La violencia laboral en cualquiera de sus modalidades se halla influenciada por múltiples factores, dando lugar a cambios fisiológicos, psicológicos, sociales y organizacionales, y los entornos de urgencias y emergencias presentan una incidencia de hasta cinco veces más con respecto al resto de servicios sanitarios. El objetivo de este estudio es analizar las características que desarrollan los profesionales sanitarios y no sanitarios de los servicios de urgencias hospitalarios (SUH) que sufren violencia laboral física y no física. METODO: Es un diseño trasversal, descriptivo-analítico mediante la aplicación de un formulario de 121 ítems a una muestra de 584 profesionales sanitarios y no sanitarios de 12 hospitales españoles con SUHS, se aplicó análisis estadístico para magnitud del evento y análisis de clúster mediante método stepwise con solución de autoclustering y posterior relación de variables del estudio con violencia laboral. RESULTADOS: Tras la aplicación inicial del método descrito, se conformaron 2 grupos, el primero de ellos incluye a 298 casos y se caracteriza por puntuaciones altas en violencia no física (media: 51,5, desviación estándar: 7,9) y bajas en física (4,8, 2,9). Por otro lado, el segundo grupo está compuesto por 285 casos y se caracteriza por puntuaciones intermedias en violencia no física (27,1, 8,4) y bajas en física (3,4, 1,3). CONCLUSIONES: En los SUH existen manifestaciones de violencia laboral no física que presentan una mayor incidencia que las manifestaciones de violencia física. Aquellos profesionales con elevada exposición a violencia laboral, y en concreto a violencia no física, presentan alteraciones biopsicosociales y organizacionales.

RESUMO

Objetivo: Evaluar la relación entre los costes asociados al número y días de ingresos previos y posteriores a la inclusión a la Unidad de pacientes crónicos complejos (PCC). Métodos: Se realizó un análisis de coste-efectividad, descriptivo, con cálculo de medias y desviaciones típicas; además de utilizar la t-Student para muestras pareadas, con el software SPSS v20.0, para un nivel de significación alfa <0,05. Los resultados del cómputo se obtuvieron de la Unidad de Codificación de los pacientes captados por la enfermera gestora de casos, y que sobrevivieron un año en seguimiento por la Unidad PCC. Resultados: Se captaron un total de 132 PCC, con un total de 563 ingresos previos, a 204 post inclusión. La media de número de ingresos al año antes fue de 4,27 (DT: 3,35), y se redujo a 1,55 (DT: 1,74). Por otro lado, el número de días de estancia hospitalaria total se redujo de 3.835 a 1.897 días, que equivale una diferencia de coste estimado en 11165.164,36 de euros. La media de días de ingreso antes fue de 29,05, y se redujo a 14,37 días, encontrando una significación estadística (p<0,001) entre días de ingresos previos y posteriores. Conclusiones: La inclusión en la Unidad PCC garantiza, mediante el liderazgo por la enfermera gestora de casos, una mejora coste-efectiva sin gastos añadidos, por optimizar recursos ya existentes interniveles asistenciales, mediante la identificación de PCC y sus necesidades prioritarias, planificación al alta con informes individualizados y garantizando el contacto. (AU)


Objective: Evaluate the relationship between the costs associated with the number and days of admission before and after inclusion in the Complex Chronic Patients Unit (CCP). Methods: A descriptive cost-effectiveness analysis was performed, with calculation of arithmetic averages and standard deviations; in addition to using the t-Student for paired samples, with the SPSS Enfermería GlobalNº 72 Octubre 2023Página 78v20.0 software, for a significance level alpha <0.05. The results of the computation were obtained from the Coding Unit of the patients recruited by the case manager nurse, who survived one year of follow-up by the CCP Unit. Results: A total of 132 CCP were recruited, with a total of 563 previous admissions, which were reduced to 204 post inclusion. The average number of admissions of the previous year was 4.27 (SD: 3.35), and it was reduced to 1.55 (SD: 1.74). On the other hand, the number of days of total hospital stay was reduced from 3,835 to 1,897 days, which is equivalent to a difference in estimated cost of 11,165,164.36 euros. The average number of days of admission before was 29.05, and it was reduced to 14.37 days, finding a statistical significance (p<0.001) between days of admission before and after. Conclusions: Inclusion in the CCP Unit guarantees, through the leadership of the case manager nurse, a cost-effective improvement without added expenses, by optimizing already existing interlevel care resources, through the identification of CCP and their priority needs, discharge planning with reports individualized and guaranteeing contact.

RESUMO

Training with real patients is a critical aspect of the learning and growth of doctors in training. However, this essential step in the educational process for clinicians can potentially compromise patient safety, as they may not be adequately prepared to handle real-life situations independently. Clinical simulators help to solve this problem by providing real-world scenarios in which the physicians can train and gain confidence by safely and repeatedly practicing different techniques. In addition, obtaining objective feedback allows subsequent debriefing by analysing the situation experienced and learning from other people's mistakes. This article presents SIMUNEO, a neonatal simulator in which professionals are able to learn by practicing the management of lung ultrasound and the resolution of pneumothorax and thoracic effusions. The article also discusses in detail the hardware and software, the main components that compose the system, and the communication and implementation of these. The system was validated through both usability questionnaires filled out by neonatology residents as well as through follow-up sessions, improvement, and control of the system with specialists of the department. Results suggest that the environment is easy to use and could be used in clinical practice to improve the learning and training of students as well as the safety of patients.

RESUMO

The general lockdown decreed in Spain due to the COVID-19 pandemic interrupted the ALAS health promotion intervention aimed at the population at high risk of suffering from type 2 diabetes. We conducted a descriptive study in 2020 through a telephone survey and a comparison with baseline data to determine the impact of confinement on the lifestyles of the participants. We collected sociodemographic variables and conducted assessments before/after confinement on general health status and lifestyle (sleep, physical activity and diet). Additionally, weight, BMI and adherence to a Mediterranean diet were assessed. Descriptive statistical analyses, comparisons of pre-post confinement data and logistic regression were carried out. A total of 387 individuals responded. Among them, 31.8% reported a worse perception of health after confinement, and 63,1% reported no change. Regarding exercise, 61.1% reduced their weekly physical activity time. Regarding diet, 34,4% perceived worse quality, and 53.4% reported no change, despite the fact that 89.4% declared changes in their eating practices. Weight and BMI decreased by 3,1%, and adherence to the Mediterranean diet improved from baseline. Confinement had a negative impact on the general health, diet, sleep and physical activity of this population (at risk of diabetes); however, weight and BMI decreased, and adherence to a Mediterranean diet improved.

RESUMO

The Diet, Physical Activity and Health (Alimentación, Actividad física y Salud, ALAS) program is an intervention implemented by the municipal health services of Madrid with the objective of reducing weight and preventing diabetes in high-risk population by improving diet and physical activity. The ALAS program combines individual visits with a 10-session group workshop that takes place over a 6-month period. This study evaluated the effectiveness of the ALAS intervention implemented under real-life conditions between 2016 and 2019. The intervention was evaluated with a pre- and post-intervention study with follow-up performed 6 and 12 months from the start of the program. The analyzed outcomes were a 5-10% reduction in the initial weight, body mass index (BMI), waist circumference and a change in glycemic status in prediabetic participants. Statistical models were adjusted by sociodemographic variables. The participants were recruited from municipal community health centers or referred by municipal occupational health services. Between 2016 and 2019, 1629 people participated in the program. At 6 months, 85% of the participants had lost weight; 43% had lost 5% or more of their initial weight, and 12% had lost 10% or more. Regarding BMI, 22.3% of participants who were initially obese were no longer obese, and 15.2% of the overweight participants achieved normal weight. A total of 35.1% of the prediabetic participants reverted to normoglycemic status. The intervention was found to be more effective for men, for those who completed the intervention and those who accessed the program through the occupational health route. Among the participants who accessed the intervention via the community, the intervention was more effective in those with a high educational level. The evaluation demonstrated the effectiveness of the ALAS program for reducing weight and the risk of developing Type 2 diabetes when applied under real-life conditions. The effectiveness of the intervention differed according to gender, access route and educational level of the participants.

RESUMO

At the beginning of the pandemic, we observed that lithium carbonate had a positive effect on the recovery of severely ill patients with COVID-19. Lithium is able to inhibit the replication of several types of viruses, some of which are similar to the SARS-CoV-2 virus, increase the immune response and reduce inflammation by preventing or reducing the cytokine storm. Previously, we published an article with data from six patients with severe COVID-19 infection, where we proposed that lithium carbonate could be used as a potential treatment for COVID-19. Now, we set out to conduct a randomized clinical trial number EudraCT 2020-002008-37 to evaluate the efficacy and safety of lithium treatment in patients infected with severe SARS-CoV-2. We showed that lithium was able to reduce the number of days of hospital and intensive care unit admission as well as the risk of death, reduces inflammatory cytokine levels by preventing cytokine storms, and also reduced the long COVID syndromes. We propose that lithium carbonate can be used to reduce the severity of COVID-19.

RESUMO

Introduction: While non-invasive positive-pressure ventilation (NIPPV) is increasingly used as a mode of respiratory support for preterm infants, it remains unclear whether this technique translates into improved respiratory outcomes. We assessed the association between NIPPV use and bronchopulmonary dysplasia (BPD)-free survival in never intubated very preterm infants. Methods: This multicenter cohort study analyzed data from the Spanish Neonatal Network SEN1500 corresponding to preterm infants born at <32 weeks gestational age and <1,500 g and not intubated during first admission. The exposure of interest was use of NIPPV at any time and the main study outcome was survival without moderate-to-severe BPD. Analyses were performed both by patients and by units. Primary and secondary outcomes were compared using multilevel logistic-regression models. The standardized observed-to-expected (O/E) ratio was calculated to classify units by NIPPV utilization and outcome rates were compared among groups. Results: Of the 6,735 infants included, 1,776 (26.4%) received NIPPV during admission and 6,441 (95.6%) survived without moderate-to-severe BPD. After adjusting for confounding variables, NIPPV was not associated with survival without moderate-to-severe BPD (OR 0.84; 95%CI 0.62-1.14). A higher incidence of moderate-to-severe BPD-free survival was observed in high- vs. very low-utilization units, but no consistent association was observed between O/E ratio and either primary or secondary outcomes. Conclusion: NIPPV use did not appear to decisively influence the incidence of survival without moderate-to-severe BPD in patients managed exclusively with non-invasive ventilation.

RESUMO

BACKGROUND: The ability to retrieve specific memories is a cognitive and emotional protective factor. Among the most effective techniques to generate autobiographical memories is the use of audio-visual stimuli, particularly images. Developing and improving techniques that facilitate the generation of such memories could be highly effective in the prevention of depressive symptoms, especially in the elderly population. The aim of the present study is to examine how the level of personal relevance of pictures as autobiographical memory cues to induce positive emotions may affect an individual's emotion regulation. METHODS: The participants, 120 older adults aged 65 and over and 120 young adults aged between 18 and 35, of both sexes and without depressive symptoms, will be induced to a negative mood state by means of viewing a film clip. Following the negative mood induction, the participants will be shown positive images according to experimental group to which they were randomly assigned (high personal relevance: personal autobiographical photographs; medium personal relevance: pictures of favourite locations associated with specific positive autobiographical memories; and low personal relevance: positive images from the International Affective Picture System). We will analyse the differences in subjective (responses to questionnaires) and objectives measures (EEG signal, heart rate variability and electrodermal activity) between the groups before and after the induction of negative affect and following the recall of positive memories. DISCUSSION: The use of images associated with specific positive autobiographical memories may be an effective input for inducing positive mood states, which has potentially important implications for their use as a cognitive behavioural technique to treat emotional disorders, such as depression, which are highly prevalent among older adults.

RESUMO

Schizophrenia is characterised by difficulty understanding the thoughts and intentions of other people. Misunderstandings could lead people to attribute hostility to others' actions. Theories suggest that we use our autobiographical memories to inform our understanding of other people but no study has examined the relation between memory and hostile attributions in schizophrenia. People with (n = 42) and without (n = 34) schizophrenia diagnoses completed The Ambiguous Intentions and Hostility Questionnaire (AIHQ) to assess their tendency to attribute hostility to other people's actions and the Autobiographical Memory Test (AMT) to assess their ability to recall specific positive and negative autobiographical memories. In linear regressions the interaction between diagnostic group and the proportion of specific negative memories participants retrieved explained significant variance in each AIHQ index. Follow-up correlation analyses showed that participants with schizophrenia who retrieved more negative memories also attributed greater hostility to other people's actions (r = 0.47) and reported that they would respond with greater aggression (r = 0.59). These correlations were in the opposite direction for controls. People with schizophrenia may use their memories for negative past events to understand the actions and intentions of other people, leading to attributions of hostility for otherwise benign actions.

RESUMO

Humans can contract anisakiasis by eating fish or squid containing live larvae of the third stage (L3) of the parasitic nematodes of the genus Anisakis, majorly from Anisakis simplex s.s. and Anisakis pegreffii, sibling species of the A. simplex s.l. complex. Most cases diagnosed molecularly are due to A. simplex s.s., although A. pegreffii has also been identified in human cases. Cathepsins are mostly lysosomal multifunctional cysteine proteases and can participate in the pathogenicity of parasites. Cathepsin B and L activities were investigated in the two sibling species of Anisakis mentioned. L3 and L4 of both species were collected during their in vitro development, and cathepsin activity was determined in the range of pH 4.0-8.5, using specific fluorogenic substrates. The activity detected with the substrate Z-FR-AMC (N-α-benzyloxycarbonyl-L-phenylalanyl-L-arginine-7-amido-4-methyl-coumarin) was identified as cathepsin L (optimum pH = 5.0, range 4.0-6.0, p < 0.001). Activity was highest in L3 freshly collected from fish, especially in A. simplex s.s., and decreased during development, which could be related to virulence, invasion of host tissues, and/or intracellular digestion. Cathepsin B-like activity was not identified with either of the substrates used (Z-RR-AMC [N-α-benzyloxycarbonyl-L-arginyl-L-arginine-7-amido-4-methyl-coumarin] and Z-FR-AMC). With Z-RR-AMC, cleaving activity was detected almost exclusively in L4 of A. simplex s.s. (p < 0.05) with optimum pH = 8.0 (range 7.0-8.5). Assays with class-specific protease inhibitors showed that this activity was mainly due to serine proteases [up to 90% inhibition with 4-(2-aminoethyl) benzenesulfonyl fluoride hydrochloride (AEBSF)], although metalloproteases (up to 40-45% inhibition with 1,10 phenanthroline) and slight cysteine protease activity (<15% inhibition with E64 [L-trans-epoxysuccinyl-leucylamido-(4-guanidino)-butane]; putative cathepsin B-like) were also detected. These results show differential serine protease activity between sibling Anisakis species, regulated by larval development, at least in A. simplex s.s. The higher cathepsin L and serine protease activities detected in this species could be related to its greater pathogenicity, reported in experimental animals, compared to that of A. pegreffii.

RESUMO

The triarchic model of psychopathy encompasses different conceptions of psychopathic personality characterized by three phenotypic components: boldness, disinhibition, and meanness. Psychopathy is a complex construct at both emotional and behavioral level. The aim of this study was to determine the core elements of psychopathic personality in a community sample and analyze the relation between these elements and other personality traits such as aggression, and certain specific behavioral manifestations such as substance use. The study sample comprised 1,159 participants aged between 17 and 74 years, who were administered the Triarchic Psychopathy Questionnaire, the Impulsive-Premeditated Aggression Scale, and the Aggression Questionnaire. The results show that the constructs of meanness and disinhibition are more highly associated with different forms of both impulsive and premeditated aggression. Furthermore, men scored higher on all three components of the triarchic model compared to women. Finally, higher substance use (tobacco and drugs) was associated with higher scores in meanness, boldness, and disinhibition. These findings demonstrate the importance of assessing psychopathy in a community sample, and the detection of possible risk factors for the disorder.

RESUMO

Proteolytic activity was studied in two sibling species of Anisakis (Nematoda: Anisakidae), A. simplex s.s. and A. pegreffii, throughout their in vitro development from third larval stage (L3) from the host fish (L3-0h) to fourth larval stage (L4) obtained in culture. Proteases have a significant role in the lifecycle of the parasite and in the pathogen-host relationship. Proteolytic activity peaks were detected at pH 6.0 and 8.5. Protease activity was detected in all the developmental stages of the two species studied at both pH values. These pH values were used for assaying with specific inhibitors which permitted the determination of metalloprotease activity, and, to a lesser extent, that of serine and cysteine protease. Aspartic protease activity was only detected at pH 6.0. At this pH, L4 larvae showed higher proteolytic activity than L3 larvae in both species (p < 0.001), the majority of activity being due to metalloproteases and aspartic proteases, which could be related to nutrition, especially the latter, as occurs in invertebrates. At pH 8.5, proteolytic activity was higher in A. simplex s.s. than in A. pegreffii (p < 0.01). At this pH, the majority of activity was due to metalloproteases in all developmental phases of both species, although, in L3-0h, the activity of these proteases was significantly higher (p < 0.03) in A. simplex s.s. than in A. pegreffii. This could be related to the greater invasive capacity of the former. Serine proteases have frequently been implicated in the invasive capacity and pathogenicity of some parasites. This may be related to the significantly higher activity (p ≤ 0.05) of serine protease in all the larval stages of A. simplex studied at pH 6.0. Thus, there are interspecific differences in proteases that have been related to pathogenesis in nematodes. These differences could thus be contributing to the previously reported differences in pathogenicity between these two Anisakis species.

RESUMO

BACKGROUND: We describe the investigation undertaken and the measures adopted to control a Serratia marcescens outbreak in the neonatology unit of La Paz University Hospital in Madrid, Spain. METHODS: Weekly rectal and pharyngeal screenings for S marcescens were performed in the neonates starting after detection of the outbreak. Environmental samples and samples from health care workers (HCWs) were obtained for microbiological analysis. An unmatched case-control study was carried out to investigate risk factors for infection/colonization. RESULTS: The outbreak began in June 2016 and ended in March 2017, affecting a total of 59 neonates. Twenty-five (42.37%) neonates sustained an infection, most frequently conjunctivitis and sepsis. Multivariate logistic regression identified the following risk factors: parenteral nutrition (odds ratio [OR], 103.4; 95% confidence interval [CI], 11.9-894.8), history of previous radiography (OR, 15.3; 95% CI, 2.4-95.6), and prematurity (OR, 5.65; 95% CI, 1.5-21.8). Various measures were adopted to control the outbreak, such as strict contact precautions, daily multidisciplinary team meetings, cohorting, allocation of dedicated staff, unit disinfection, and partial closure. Hands of HCWs were the main suspected mechanism of transmission, based on the inconclusive results of the environmental investigation and the high number of HCWs and procedures performed in the unit. CONCLUSIONS: S marcescens spreads easily in neonatology units, mainly in neonatal intensive care units, and is often difficult to control, requiring a multidisciplinary approach. Strict measures, including cohorting and medical attention by exclusive staff, are often needed to get these outbreaks under control.

RESUMO

PURPOSE: We have shown that GPC3 overexpression in breast cancer cells inhibits in vivo tumor progression, by acting as a metastatic suppressor. GPC3-overexpressing cells are less clonogenic, viable and motile, while their homotypic adhesion is increased. We have presented evidences indicating that GPC3 inhibits canonical Wnt and Akt pathways, while non-canonical Wnt and p38MAPK cascades are activated. In this study, we aimed to investigate whether GPC3-induced Wnt signaling inhibition modulates breast cancer cell properties as well as to describe the interactions among pathways modulated by GPC3. METHODS: Fluorescence microscopy, qRT-PCR microarray, gene reporter assay and Western blotting were performed to determine gene expression levels, signaling pathway activities and molecule localization. Lithium was employed to activate canonical Wnt pathway and treated LM3-GPC3 cell viability, migration, cytoskeleton organization and homotypic adhesion were assessed using MTS, wound healing, phalloidin staining and suspension growth assays, respectively. RESULTS: We provide new data demonstrating that GPC3 blocks-also at a transcriptional level-both autocrine and paracrine canonical Wnt activities, and that this inhibition is required for GPC3 to modulate migration and homotypic adhesion. Our results indicate that GPC3 is secreted into the extracellular media, suggesting that secreted GPC3 competes with Wnt factors or interacts with them and thus prevents Wnt binding to Fz receptors. We also describe the complex network of interactions among GPC3-modulated signaling pathways. CONCLUSION: GPC3 is operating through an intricate molecular signaling network. From the balance of these interactions, the inhibition of breast metastatic spread induced by GPC3 emerges.

RESUMO

Repetitive thought may have adaptive and functional consequences, depending on, among other things, the interpretation of the content: analytical or abstract (general and decontextualized) and experiential or concrete (specific, contextual and incidental). Studies experimentally manipulating repetitive thought have shown both the constructive consequences of the experiential mode and the dysfunctional consequences of the analytical mode. The aim of the current study is to observe the effect of analytical and experiential rumination of negative self-defining memories on schizotypic symptoms. A sample of 111 university students were randomly assigned to one of the two experimental conditions of induced rumination, "analytical" or "experimental." The participants completed a series of questionnaires (anomalous perception of reality, preoccupation and depression) and a negative self-defining memory was obtained to be used as the content of the induced rumination. Following the rumination induction, participants in the experiential condition significantly decreased their scores on anomalous perception of reality compared with those in the analytical condition. We also observed that post-induction scores on self-reported sadness significantly increased in both experimental conditions while scores on self-reported happiness decreased. Our results show that the concrete/experiential rumination, focused here on negative self-defining memories, have positive consequences on schizotypic symptoms, such as decreased anomalous perception of reality.

RESUMO

BACKGROUND: Debate still remains on whether the presence of early recruited collateral circulation (ERCC) in the setting of an acute coronary occlusion (ACO) has a prognosis benefit. Some previous reports have shown lower mortality and morbidity rates in well-collateralized patients compared with those with poorly recruited collateral circulation (PCC), but others have not. In the primary angioplasty era, the role of collateral circulation in these studies may have been influenced by the effect of early reperfusion. The actual impact of ERCC in ACO can be clarified by studying its effect on nonreperfused patients. OBJECTIVE: This study aimed to compare the 1-year clinical outcome in nonreperfused late presentation ACO in a major coronary artery with ERCC versus PCC. PATIENTS AND METHODS: Between 2008 and 2015, we included 164 patients with a nonreperfused late presentation ACO. The patients were divided according to the presence of angiographic ERCC (Rentrop 2-3) or PCC (Rentrop 0-1). ERCC was present in 54% of patients. Patients with ERCC less often presented with cardiogenic shock (P=0.02) and the right coronary artery was the most frequent culprit vessel (P=0.02). The presence of PCC was associated independently with higher 1-year cardiovascular mortality [hazard ratio (HR): 6.92; 95% confidence interval (95%CI): 1.37-34.7; P=0.019], 1-year total mortality (HR: 5.79; 95%CI: 1.95-17.1; P=0.001), and 1-year major adverse cardiac event (HR: 8.05; 95%CI: 1.73-37.4; P<0.01). CONCLUSION: The presence of angiographically PCC in the setting of late presentation nonreperfused ACO is relatively infrequent (46%) and is associated with worse 1-year major clinical outcomes.

RESUMO

The infection of blue whiting Micromesistius poutassou from the western Mediterranean Sea, off the eastern coast of Spain, with larvae of Anisakis spp. was studied. Between April 2016 and April 2017, 140 fish were analyzed. Total epidemiological data showed that the prevalence of Anisakis spp. was 29.3% and the mean intensity 1.8. Of the 74 larvae collected, 61% were type I and the remaining 39%, type II. Of the former, 91% were molecularly identified as Anisakis pegreffii (P = 19.3%; MI = 1.4), 2.2% as Anisakis simplex s.s. (P = 0.7%; MI = 1.0), while the rest (6.7%) showed a recombinant genotype between the two (P = 2.1%; MI = 1.0). All the type II larvae analyzed were molecularly identified as Anisakis physeteris (P = 10.0%; MI = 2.1). Three fish (2.1%) were found to have larvae in the muscle, while two were found with 1 larva of A. pegreffii and one with two larvae (1 A. simplex s.s. and 1 A. pegreffii). Statistical analysis showed that the prevalence of Anisakis spp. in blue whiting was higher in spring than in autumn (P < 0.001), probably due to the greater size (and age) of the fish and related to factors as diet shift, accumulation with age and higher food intake. Analysis of the data suggested that blue whiting were first infected with Anisakis type I (mean age 2.3 years) and later with Anisakis type II (mean age 2.7 years), probably due to the diet changing with age, with the incorporation of the paratenic/intermediate host species of these parasites. In any case, the public health authorities must continue to emphasize the need for suitable thermal treatment (freezing or cooking) of the fish prior to consumption.

RESUMO

The development of the fourth larval stage (L4) of Anisakis physeteris was studied using scanning electron microscopy (SEM), comparing it with third larval stage (L3) recently obtained from the host fish, blue whiting (Micromesistius poutassou), from the western Mediterranean Sea (east coast of Spain, zone FAO 37.1.1). After molting to L4, samples of the parasite were examined at different times in order to observe their development. Following collection of the L4, a small portion was taken from the middle of the larva for molecular identification, confirming in all cases that it was A. physeteris. The anterior and posterior sections of the larvae were prepared for morphological study by SEM. The development of a row of denticles on each of the three prominent lips, almost reaching the buccal commisures, was observed in the L4. Pores of unknown function were found in the upper external part of each lip. Clearly developed cephalic papillae, amphids, and deirids were also observed in L4, while, although present in L3, these were beneath the cuticle. Phasmids were detected in L4 but not in L3. The L4 tail finished in a conical lobe with a blunt point, absent in L3. In the oldest L4, some preanal papillae were observed beneath the cuticle in males, while, in females, the vulva could be seen by light microscopy, apparently still covered by the cuticle.
