Cambios en los índices parasitarios de Cnesterodon decemmaculatus (Cyprinodontiformes: Poeciliidae) del arroyo Rodríguez (La Plata-Pcia. Bs. As.) en condiciones de laboratorio

Cnesterodon decemmaculatus es un pez vivíparo que se distribuye en las cuencas de los ríos Paraná, Uruguay y Río de la Plata. Presenta tolerancia a variaciones fisicoquímicas y una dieta omnívora. En este trabajo se analizó la variación en la intensidad, densidad y prevalencia parasitaria de C. decemmaculatus en condiciones de laboratorio. Se colectaron 122 ejemplares del Arroyo Rodríguez (La Plata- Pcia.Bs.As), se trasladaron con agua del sitio de muestreo al laboratorio y se mantuvieron en acuarios a temperatura ambiente. Durante 9 semanas se realizó la búsqueda de parásitos en cada uno de los órganos de los peces. Se colectaron metacercarias Ascocotyle sp. en el corazón, metacercarias Echinostomatidae en músculo y branquias, monogeneos en branquias y superficie del cuerpo, metacestodes y nematodes en el mesenterio, y trichodinas en branquias.Asociación Parasitológica Argentin

Effects of the passage of Comet C/2013 A1 (Siding Spring) observed by the Shallow Radar (SHARAD) on Mars reconnaissance orbiter

The close passage of Comet C/2013 A1 (Siding Spring) to Mars provided a unique opportunity to observe the interaction of cometary materials with the Martian ionosphere and atmosphere using the sounding radar SHARAD (SHAllow RADar) aboard Mars Reconnaissance Orbiter. In two nightside observations, acquired in the 10 h following the closest approach, the SHARAD data reveal a significant increase of the total electron content (TEC). The observed TEC values are typical for daylight hours just after dawn or before sunset but are unprecedented this deep into the night. Results support two predictions indicating that cometary pickup O+ ions, or ions generated from the ablation of cometary dust, are responsible for the creation of an additional ion layer

The Recovery Orientation of a Farm Community for Severe Autism — Data from the DREEM-IT (Developing Recovery Enhancing Environment Measures — Italian Version)

Recent years have witnessed an increasing interest in the concept of ‘recovery’ in the field of mental health and psychiatry. Autism is a neurodevelopmental disorder characterized by qualitative impairments in social interaction and communication skill, along with a restricted, repetitive, and stereotyped pattern of behavior and interests. The diagnosis is lifelong and can be a major impediment to independent living. It has been previously demonstrated that organized and structured forms of intervention, starting from early childhood and developing during all the different life stages, may improve outcome and quality of life in patients with autism. It is therefore conceivable that diverse forms of recovery (e.g. optimal level of motivation, skills, social involvement) may be possible in autism. There are no fully developed tools with which to evaluate the recovery orientation of a service, but the National Institute for Mental Health in England (NIMHE) has identified the Developing Recovery Enhancing Environments Measure (DREEM) as the most promising of an emerging group of recovery sensitive measures. This study explores the use of DREEM, as a tool to evaluate the effectiveness of recovery-based care in an Italian farm community center specifically designed for adult patients with autism and intellectual disability

Modifications of Chest CT Body Composition Parameters at Three and Six Months after Severe COVID-19 Pneumonia: A Retrospective Cohort Study

We aimed to describe body composition changes up to 6-7 months after severe COVID-19 and to evaluate their association with COVID-19 inflammatory burden, described by the integral of the C-reactive protein (CRP) curve. The pectoral muscle area (PMA) and density (PMD), liver-to-spleen (L/S) ratio, and total, visceral, and intermuscular adipose tissue areas (TAT, VAT, and IMAT) were measured at baseline (T0), 2-3 months (T1), and 6-7 months (T2) follow-up CT scans of severe COVID-19 pneumonia survivors. Among the 208 included patients (mean age 65.6 ± 11 years, 31.3% females), decreases in PMA [mean (95%CI) -1.11 (-1.72; -0.51) cm2] and in body fat areas were observed [-3.13 (-10.79; +4.52) cm2 for TAT], larger from T0 to T1 than from T1 to T2. PMD increased only from T1 to T2 [+3.07 (+2.08; +4.06) HU]. Mean decreases were more evident for VAT [-3.55 (-4.94; -2.17) cm2] and steatosis [L/S ratio increase +0.17 (+0.13; +0.20)] than for TAT. In multivariable models adjusted by age, sex, and baseline TAT, increasing the CRP interval was associated with greater PMA reductions, smaller PMD increases, and greater VAT and steatosis decreases, but it was not associated with TAT decreases. In conclusion, muscle loss and fat loss (more apparent in visceral compartments) continue until 6-7 months after COVID-19. The inflammatory burden is associated with skeletal muscle loss and visceral/liver fat loss

Análisis molecular de los genes COI y 28S de un copépodo de la familia Pennellidae parásito de <i>Cubiceps caeruleus</i> (Actinopterygii: perciformes: nomeidae)

Durante la inspección de peces provenientes de pescadores locales se encontró un ejemplar de Cubiceps caeruleus que alojaba en el pedúnculo caudal dos copépodos de la Familia Pennellidae. El cuello del copépodo era muy largo y se extendía hacia la región anterior anclándose cerca de la columna vertebral del hospedador. Luego de la disección, se observó el extremo anterior con proyecciones que coinciden a las descriptas para el género Sarcotretes sp. Las piezas bucales no pudieron recuperarse en su totalidad por lo cual fue imposible asignarle el nombre específico.Facultad de Ciencias Naturales y MuseoCentro de Estudios Parasitológicos y de Vectore

Análisis de adultos de Clinostomum sp. identificadas en base a datos moleculares, parásitas de Ardea cocoi

Durante un estudio parasitológico de dos garzas (Ardea cocoi) provenientes de Magdalena (Buenos Aires) y el Rincón, Dpto. la Capital (Santa Fe) se encontraron en cavidad oral y esófago digeneos de la familia Clinostomidae. Ejemplares de dichos parásitos se guardaron en alcohol 96% para estudios moleculares y otros fueron conservados en formol para realizar tinciones y estudios morfológicos. Se secuenció el gen COI de 4 ejemplares, dos provenientes de cada provincia. Las secuencias obtenidas se editaron en el programa Geneious y a partir de secuencias de la familia Clinostomidae depositadas en el Genbank se construyó una matriz que se alineó en la plataforma online MAFFT. Con el programa MEGA X se calculó la distancia génica (p-value).Asociación Parasitológica Argentin

Health professionals who have worked in COVID-19 immunization centers suffer the effects of violence

BackgroundThe phenomenon violence against health professionals has received increasing attention in recent years because of its frequency and significant impact on victims’ mental health and disruption of health services. Despite this attention, little is known about the incidence of workplace violence in the highly politicized immunization services. Therefore, we decided to examine the prevalence of workplace violence in the COVID-19 immunization campaign, the risk and protective factors, and the impact on victims’ mental health.MethodsBetween March and April 2022, we conducted an anonymous online survey among health professionals working in COVID-19 vaccination centers in the Friuli-Venezia Giulia Region (Italy). We used the Questionnaire for Workplace Violence in Healthcare Settings and the Impact of Event Scale–Revised.ResultsOf the 200 participants, 93 (46.5%) reported being victims of an act of violence during the vaccination campaign, 60 of them verbally and 7 physically. In 35.5% of cases, the IES score indicated a possible post-traumatic stress reaction in the victim. Opinions on measures to prevent violence and support workers in the workplace differed according to the sex of the health professional, with women emphasizing the need for self-defense training and improvement of security arrangements (p &lt; 0.001).ConclusionOne-third of health professionals involved in the COVID-19 immunization campaign reported that their mental health was affected by workplace violence. Public health professionals dealing with politicized and debated issues such as immunization should receive more attention, as should the implementation of a more structured and multidisciplinary approach to the problem within healthcare organizations
