RESUMEN

Destination memory can be defined as the capacity to remember to whom we transmit information. It is measured through the accuracy of retrieving the association between the information we transmit and the person to whom we transmit it. A destination memory procedure aims to emulate human interaction by sharing facts with celebrities (i.e., familiar faces) since we often communicate with people we know. However, the role of the choice about who we intend to transmit the information to has not been evaluated before. This paper investigated whether deciding with whom to share a piece of information benefits destination memory. We designed two experiments with different levels of cognitive load, increasing it from Experiment 1 to Experiment 2. The experiments included two conditions: the choice condition, in which participants chose from two options to whom they desired to share a fact, and the no-choice condition, in which participants simply shared facts with celebrities without the possibility of a choice. Experiment 1 suggested that a choice component did not affect destination memory. However, when in Experiment 2 we raised the cognitive load by increasing the number of stimuli, we found that selecting the recipient during the more challenging task provided an advantage in destination memory. This result is congruent with the explanation that the shift of the participants' attentional resources to the recipient, caused by the choice component, leads to a destination memory improvement. In sum, it seems that a choice component can improve destination memory only under demanding attentional conditions.

RESUMEN

In two experiments we examined the role of language proficiency and associative strength in the production of false memory. We constructed Deese-Roediger-McDermott lists using both Spanish and English free association norms. Lists were constructed to vary in backward associative strength (BAS). Experiment 1 participants were native Spanish speakers with some proficiency in English while Experiment 2 participants were native Spanish participants that had either high, intermediate, or low English proficiency. Results showed that, in both Experiment 1 and Experiment 2, false recognition was greater in participants' dominant language (L1 or Spanish) than in their non-dominant language (L2 or English), and false recognition in L2 increased with L2 proficiency when low-BAS lists were studied (Experiment 2). Further, false recognition was higher in high-BAS lists than in low-BAS lists in both L1 and L2. Finally, we collected a measure of participants' knowledge of our stimulus words in L2. These data showed that participants had far from perfect knowledge of all L2 stimuli. Analyses that factored out the effects of L2 word knowledge failed to alter the effects of L1 vs. L2, L2 proficiency and BAS on false recognition.

RESUMEN

Minute virus of canines (MVC) belongs to the family Parvoviridae, genus Bocaparvovirus, and has been mainly described during enteritis episodes in young dogs. This study reports the characterization of four divergent MVC strains detected between 2012 and 2018, three of which were from dogs illegally imported into Italy, most probably from Eastern Europe, that cluster together phylogenetically but share low genetic similarity with the fourth MVC from an autochthonous dog and other available MVC sequences. Our data indicate that the introduction of genetically distinct MVC strains occurred through the illegal movement of dogs from a geographic area where a distinct MVC lineage was most likely circulating. Enforced surveillance of MVC in the dog population of Eastern Europe and its neighboring countries may shed light on, and eventually trace back to, illegal animal movements.

RESUMEN

BACKGROUND/OBJECTIVE: The pathogenesis of infantile hemangiomas (IH), PHACE, and LUMBAR syndromes remains unknown. We aim to describe histopathologic features of midline anomalies associated with IH, including patients with PHACE and LUMBAR syndromes. METHODS: A multicenter retrospective chart review was performed to identify patients with IH, PHACE, and LUMBAR syndrome with histopathologic specimens from sternal or midline anomalies. A total of 18 midline lesions from 13 patients were included. Out of 18, 14 midline lesions underwent both histopathologic and clinical review. Three hamartoma-like chin plaques and one supraumbilical raphe underwent only clinical review. RESULTS: All 13 patients had midline lesions and IH. Histopathologic diagnoses were as follows: rhabdomyomatous mesenchymal hamartoma (3), folliculosebaceous cystic hamartoma (1), fibroepithelial polyp (1), verrucous epidermal hyperplasia with vascular proliferation and fibroplasia (1), congenital midline cervical cleft (1), pericardium with fibrosis (1), fibrous components with increased collagen (1), atrophic skin/membrane (3), angiolipomatous mass with neural components (1), and lipomatous mass (1). Due to the retrospective nature of this study, it was not possible to obtain pathology slides for all midline lesions that had previously been biopsied or resected. We show clinically and histopathologically a new association between PHACE syndrome and rhabdomyomatous mesenchymal hamartoma (RMH), in addition to demonstrating the association between PHACE syndrome and chin hamartomas. We also display histopathologic findings seen in midline lesions resected from LUMBAR patients. CONCLUSION: Rhabdomyomatous mesenchymal hamartoma is thought to be related to aberrations of mesenchymal cells during development; therefore, this may provide clues to the pathogenesis of IH and related syndromes.

RESUMEN

Precalcaneal congenital fibrolipomatous hamartoma is an underreported benign entity that has been described in the literature under different names. We present two cases of unilateral fibrolipomatous hamartoma (FLH) appearing in a unique location: on the posterior aspect of the foot overlying the heel. We propose the term "FLH of the skin" as a more inclusive and less confusing term for this condition, thus allowing distinction with FLH arising from neural tissue. High-frequency ultrasonography appears to be a useful diagnostic tool that may avoid unnecessary biopsies for this condition.

RESUMEN

Mammalian Orthoreoviruses 3 (MRV3) have been described in diarrheic pigs from USA and Asia. We firstly detected MRV3 in Europe (Italy) in piglets showing severe diarrhea associated with Porcine Epidemic Diarrhea. The virus was phylogenetically related to European reoviruses of human and bat origin and to US and Chinese pig MRV3.

RESUMEN

Notalgia paresthetica is characterized by a hyperpigmented macular pruritic skin lesion most commonly localized unilaterally in the middle and upper back region. This condition has been reported in association with multiple endocrine neoplasia syndrome type 2A (MEN 2A) in several families; it rarely affects children and it may serve as an early marker of MEN 2A. We report a 9-year-old girl diagnosed with MEN 2A and notalgia paresthetica.

RESUMEN

False-memory illusions have been widely studied using the Deese/Roediger-McDermott paradigm (DRM). In this paradigm, words semantically related to a single nonpresented critical word are studied. In a later memory test, critical words are often falsely recalled and recognized. The present normative study was conducted to measure the theme identifiability of 60 associative word lists in Spanish that include six words (e.g., stove, coat, blanket, scarf, chill, and bonnet) that are simultaneously associated with three critical words (e.g., HEAT, COLD, and WINTER; Beato & Díez, Psicothema, 26, 457-463, 2011). Different levels of backward associative strength were used in the construction of the DRM lists. In addition, we used two types of instructions to obtain theme identifiability. In the without-explanation condition, traditional instructions were used, requesting participants to write the theme list. In the with-explanation condition, the false-memory effect and how the lists were built were explained, and an example of a DRM list and critical words was shown. Participants then had to discover the critical words. The results showed that all lists produced theme identifiability. Moreover, some lists had a higher theme identifiability rate (e.g., 61 % for the critical words LOVE, BOYFRIEND, COUPLE) than others (e.g., 24 % for CITY, PLACE, VILLAGE). After comparing the theme identifiabilities in the different conditions, the results indicated higher theme identifiability when the false-memory effect was explained than without such an explanation. Overall, these new normative data provide a useful tool for those experiments that, for example, aim to analyze the wide differences observed in false memory with DRM lists and the role of theme identifiability.

RESUMEN

Currently, screening for anal high-grade squamous intraepithelial lesions (anal HSIL) relies on anal cytology and high-resolution anoscopy. Since this approach has limited sensitivity and specificity for detecting anal HSIL, there is increasing interest in the role of biomarkers for predicting anal HSIL. The aim of this study is to evaluate the diagnostic accuracy of HPV E6/E7-mRNA expression for the detection of anal HSIL in MSM infected with HIV, in comparison to DNA-HR-HPV and anal cytology. This cross-sectional screening study included 101 MSM followed at the HIV-unit of La Paz University Hospital. Intra-anal swabs from patients participating in a screening program including cytology, high-resolution anoscopy and histology were analyzed. HR-HPV-DNA detection was performed by means of the CLART® HPV2 assay (GENOMICA S.A.U., Madrid, Spain). E6/E7-mRNA detection of HR-HPV-types 16, 18, 31, 33, and 45 was performed using the NucliSENS-EasyQ assay (BioMérieux, Marcy lEtoile, France). HR-HPV DNA and HPVE6/E7 mRNA were detected in 82% and 57% of the anal smears respectively. Anal cytology screening was abnormal in 70.3%. For the detection of HSIL sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were 71.7%, 55.6%, 57.9%, and 69.8% for E6/E7-mRNA testing, respectively, compared to 100%, 31.5%, 55.4%, and 100% for HR-HPV-DNA testing and to 83%, 40.7%, 54.9%, 73.3% of cytology testing. In comparison with the other tests, HPVE6/E7 mRNA testing yielded a lower clinical sensitivity but a higher clinical specificity and PPV for the detection of anal HSIL in MSM infected with HIV.

RESUMEN

BACKGROUND: The incidence of anal cancer among HIV-infected patients is higher than that in other populations. Anal high-grade squamous intraepithelial lesions are considered precursors to invasive squamous-cell carcinomas and are strongly associated to high-risk human papillomavirus infection. OBJECTIVE: The aim of this study is to determine the prevalence of anal high-grade squamous intraepithelial lesions through screening based on cytology and high-resolution anoscopy with biopsy in a cohort of HIV-infected men who have sex with men. DESIGN: This investigation is an observational cross-sectional cohort study. SETTING: The study was conducted in the HIV unit of a tertiary hospital in Spain. PATIENTS: Three hundred HIV-infected men who have sex with men participated. Physical examination led to a diagnosis of perianal squamous-cell carcinoma and high-grade squamous intraepithelial lesions in 2 patients who were then excluded. INTERVENTIONS: Anal liquid cytology was performed. Patients with cytological abnormalities underwent high-resolution anoscopy and biopsy. MAIN OUTCOME MEASURE: The primary outcome measured was biopsy-proven high-grade squamous intraepithelial lesions. RESULTS: The median age was 41 ± 10.5 years. The mean and nadir CD4 cell counts were 651 ± 205 cells/mm(3) (interquartile range, 438-800) and 273 ± 205 cells/mm(3) (interquartile range, 131-362). High-risk human papillomavirus was detected in 80.9% of patients, and human papillomavirus 16 was detected in 35.9% of patients. The mean number of human papillomavirus genotypes was 4.6 ± 2.9 (CI, 2-6). Anal cytology was abnormal in 40.9% of patients (n = 122/298; interquartile range, 35.4%-46.6%). High-resolution anoscopy and biopsies were performed in 119 patients. The results of histological analyses were as follows: normal, 7.7% (n = 23); condyloma, 4.3% (n = 13); anal intraepithelial neoplasia 1, 5.7% (n = 17); anal intraepithelial neoplasia 2, 14% (n = 42); and anal intraepithelial neoplasia 3, 8% (n = 24). The overall prevalence of high-grade squamous intraepithelial lesions among patients with abnormal cytology was 54% (95% CI, 45.1%-62.8%). A diagnosis of high-grade squamous intraepithelial lesions was associated with human papillomavirus 16 and human papillomavirus 51 infection, and with detection of a higher number of human papillomavirus genotypes. LIMITATIONS: High-resolution anoscopy was only performed in patients with abnormal cytology. CONCLUSIONS: The prevalence of high-risk human papillomavirus infection and high-grade squamous intraepithelial lesions is high in our cohort. Physical examination enabled straightforward diagnosis of perianal high-grade squamous intraepithelial lesions and squamous-cell carcinoma in 2 patients.

RESUMEN

The African Swine Fever Virus (ASFV) is a DNA virus of the Asfarviridae family, Asfivirus genus. It is responsible for massive losses in pig populations and drastic direct and indirect economic impacts. The ever-growing handling of ASFV pathological material in laboratories, necessary for either diagnostic or research activities, requires particular attention to avoid accidental virus release from laboratories and its detrimental economic and environmental effects. Recently, the Commission Delegated Regulation (EU) 2020/689 of 17 December 2019 repealed the Commission Decision of 26 May 2003 reporting an ASF diagnostic manual (2003/422/EC) with the minimum and supplementary requirements for ASF laboratories. This decision generated a regulatory gap that has not been addressed yet. This paper aims to describe the Italian National Reference Laboratory (NRL) efforts to develop an effective and reliable biological containment tool for ASF laboratories and animal facilities. The tool consists of comprehensive and harmonized structural and procedural requirements for ASF laboratories and animal facilities that have been developed based on both current and repealed legislation, further entailing a risk assessment and internal audit as indispensable tools to design, adjust, and improve biological containment measures.

RESUMEN

Influenza A virus (IAV) can cause high morbidity and mortality in domestic and wild avian species and it is able to infect mammals as well. IAV in cats is sporadic and self-limiting but the recent findings of high pathogenicity avian influenza virus (HPAIV) with genetic signatures of mammalian adaptation, in domestic cats, has raised new concerns about the potential role of cats in the virus ecology. The present study aimed to investigate the circulation of IAV in companion animals' shelters in North-eastern Italy. All samples were collected from feral cats living in feline colonies that were hosted in the companion animals' shelters for the requisite period to administer the veterinary treatments. Between 2021 and 2022, 389 oropharyngeal swabs and 279 sera were collected. All swabs tested negative for IAV and the only one ELISA positive serum sample resulted H5 positive by HI test with a titer of 1:80. Despite the sporadic occurrence of influenza in cats, continuous monitoring is crucial due to the evolving zoonotic nature of the virus.

RESUMEN

According to the Domestic Animal Diversity Information System (DAD-IS) of the FAO, Italy has one of the largest numbers of local small ruminant breeds among European countries. In Southern Italy, namely the Campania Region, Bagnolese and Laticauda sheep breeds and Cilentana goat breeds are considered endangered according to the DAD-IS. Conservation of endangered animal breeds is a goal of the European Union (EU). However, the role of infectious diseases as risk factors for endangered breeds has rarely been considered. Small ruminant lentiviruses (SRLV) infect sheep and goats, causing slow-progressive, persistent, and debilitating diseases that can lead to animal death and productivity loss. In this study, we investigated the presence of SRLV in Bagnolese, Laticauda, and Cilentana breeds using a commercial ELISA in parallel with an in-house ELISA. The results of the two tests were in good agreement (Cohen Kappa 0.84, 95 % CI = 0.76-0.93). Discrepancies between the two tests were resolved using western blotting. In total, 430 samples were tested (248 Bagnolese, 125 Laticauda, and 57 Cilentana). The apparent prevalence rates were 12.5 %, 6.4 %, and 1.7 % in Bagnolese, Laticauda, and Cilentana, respectively. In the molecular analysis of 11 proviral partial sequences, subtypes B2 and A24 were identified in two Bagnolese herds. Owing to the beneficial role of sheep and goat breeding in marginal areas, it is important to screen the entire population and implement control/eradication of SRLV infections in conjunction with each conservation program.

RESUMEN

Multivisceral transplantation (MvTx) is the concurrent transplantation of the stomach, pancreaticoduodenal complex, and intestine, with or without the liver. Its use is increasing worldwide as it has been considered as a therapy for patients with functional disturbance of several organs. Graft-versus-host disease (GvHD) has been a relevant clinical problem in MvTx ever since the procedure was first performed, but little has been reported about its specific cutaneous features. Our study included all pediatric patients with clinical and histopathologic evidence of cutaneous GvHD who received MvTx between October 1999 and December 2010 in University Hospital La Paz. Seventeen children underwent MvTx at our center during this period of time. Five patients developed cutaneous GvHD (29.4%). The median onset was 45.2 days after transplantation. Acute cutaneous GvHD, consisting of symmetrical maculopapular exanthema with prominent acral erythema and accentuated lesions on the face and pinnae, was clinically suspected and pathologically confirmed in four patients (80%). Three children (60%) experienced disease progression to a formation and a positive Nikolsky sign. Only one girl (20%) showed lichenoid GvHD. The first therapeutic approach was steroids and tacrolimus adjustment; many other drugs were used in refractory cases. Three of the five patients (60%) died with concomitant GvHD, the immediate cause of death being another comorbid disease. Knowledge of the features of cutaneous GvHD in MvTx allows clinicians early recognition and prompt therapeutic intervention that may prevent progression to higher-grade disease and improve outcomes for these patients.

RESUMEN

Bullous pemphigoid (BP) is an acquired autoimmune blistering disorder of unknown etiology uncommon in childhood. Unlike adult BP, infantile BP shows acral distribution and resolves rapidly with systemic steroids. We report three infants with infantile BP presenting shortly after vaccination for diphtheria, pertussis, tetanus, poliomyelitis, hepatitis B, Haemophilus influenzae B, and meningococcus C. Our cases further reinforce the causal association between childhood BP and vaccination.

RESUMEN

In the globalized world we live in, it is increasingly common for people to speak more than one language. Although research in psychology has been widely interested in the study of false memories with the Deese/Roediger-McDermott (DRM) paradigm, to date, there is a scarcity of studies comparing false memories in the first and the second language (L1 and L2, respectively). It is noteworthy that one of the most studied variables in the DRM paradigm, the backward associative strength (BAS), has hardly been studied in the L2. Moreover, the only study that recently examined this matter found differences in the knowledge of L2-word meaning between the high-BAS and low-BAS lists, which would hinder the interpretation of the BAS effect in L2 false memories. Taking all this into account, the current work examined false memories in the L1 (Spanish) and the L2 (English) as a function of BAS overcoming the limitations of the previous study. We selected DRM lists using both Spanish and English free association norms and lists were constructed to vary in BAS values while controlling the knowledge of word meaning. Results showed that false recognition was greater in the L1 or dominant language than in the L2 or non-dominant language. Furthermore, BAS modulated the false recognition in both the L1 and the L2. That is, false recognition was higher in high-BAS than low-BAS lists in both languages. Sensitivity index from the signal-detection theory helped us gain further insight into these results. The main findings are discussed in the light of theoretical models from both the false memory and the second language processing literature. Finally, practical implications and future research are provided.

RESUMEN

BACKGROUND: False memory has been extensively studied using the Deese/Roediger-McDermott paradigm. Despite the robustness of the effect, there is wide variability in the results, which is not fully understood. METHOD: Three experiments independently examined the role of backward associative strength (BAS), forward associative strength (FAS), and theme identifiability (ID) on false memories. In Experiment 1, lists varied in BAS while controlling FAS and ID. In Experiment 2, FAS was manipulated while BAS and ID were controlled. Finally, in Experiment 3, lists varied in ID while controlling BAS and FAS. Data was analyzed using both frequentist and Bayesian analyses. RESULTS: We found false memories in all three experiments. Specifically, false recognition was higher in high-BAS than in low-BAS lists in Experiment 1. In Experiment 2, false recognition was higher in high-FAS than in low-FAS lists. In Experiment 3, false recognition was lower in high-ID than in low-ID lists. CONCLUSIONS: These findings suggest that both BAS and FAS─variables that promote error-inflating processes─and ID─which promotes error-editing processes─contribute independently to the production of false memories. Splitting apart the role of these variables helps to understand the variability of false memories and to extrapolate DRM tasks to explore other cognitive domains.

RESUMEN

False memories have been extensively investigated over the past few decades using the Deese/Roediger-McDermott (DRM) paradigm. In this paradigm, participants study lists of words associatively related to a non-presented critical lure. During a memory test, these critical lures are falsely recalled or recognized. Most studies have focused on false memories that arise when both encoding and retrieval are conducted in the same language (i.e., within-language conditions), which is typically the participant's native or first language (L1). However, much less is known about false memories when critical lures appear in the memory test in a different language than the studied lists (i.e., between-language conditions), being one of them the participant's second language (L2). The main objective of this exhaustive review was to provide an overview of the current state of research on false recognition using the DRM paradigm in between-language conditions, where languages are switched between encoding and retrieval (i.e., L1L2 versus L2L1). The results revealed a language dominance effect in between-language false memories. In other words, false recognition rates were dependent on the study language, with a trend toward higher false recognition when words were enconded in the L1 (L1L2) compared to when words were encoded in the L2 (L2L1). This review enhances our understanding of how studying words in a first or second language affects false memory in the DRM paradigm, emphasizing the significance of investigating false memory in second language speakers and the necessity for further research in the field.
