RESUMO

A new method to investigate disorder in ice films is proposed and applied to acetylene ice. It is based on a quantitative analysis of the infrared spectrum data, which includes: the Brendel-Bormann model for the material's dielectric function; molecular vibration modes calculated by density functional theory (DFT); a monomer-dimer model for amorphous ice; and a peak-shape analysis through Levenberg-Marquardt nonlinear regression. Acetylene ice films with different degrees of disorder were investigated with the proposed method. The results provide an estimate of the degree of disorder in the films and indicate the possibility of existence of a second amorphous phase of acetylene ice grown at temperatures of about 15 K and then annealed. This phase would be similar to the high-density amorphous phase observed for water ice. The infrared data in this work is compared with those from the literature for acetylene gas, acetylene film, and acetylene aerosol. A qualitative analysis reveals differences in the degree of disorder in each system and points to a crystallinity limit for acetylene ice film; that is, the crystalline acetylene film has a higher degree of intrinsic disorder than the crystalline acetylene aerosol.

RESUMO

BACKGROUND: Data on long-term neurodevelopmental outcomes of normocephalic children (born with normal head circumference) exposed to Zika virus in utero are scarce. We aimed to compare neurodevelopmental outcomes in normocephalic children up to age 48 months with and without Zika virus exposure in utero. METHODS: In this prospective cohort study, we included infants from two cohorts of normocephalic children born in León and Managua, Nicaragua during the 2016 Zika epidemic. In León, all women pregnant during the two enrolment periods were eligible. In Managua, mother-child pairs were included from three districts in the municipality of Managua: all women who became pregnant before June 15, 2016, and had a due date of Sept 15, 2016 or later were eligible. Infants were serologically classified as Zika virus-exposed or Zika virus-unexposed in utero and were followed up prospectively until age 48 months. At 36 months and 48 months of age, the Mullen Scales of Early Learning (MSEL) assessment was administered. Primary outcomes were MSEL early learning composite (ELC) scores at 30-48 months in León and 36-48 months in Managua. We used an inverse probability weighting generalised estimating equations model to assess the effect of Zika virus exposure on individual MSEL cognitive domain scores and ELC scores, adjusted for maternal education and age, poverty status, and infant sex. FINDINGS: The initial enrolment period for the León cohort was between Jan 31 and April 5, 2017 and the second was between Aug 30, 2017, and Feb 22, 2018. The enrolment period for the Managua cohort was between Oct 24, 2019, and May 5, 2020. 478 mothers (482 infants) from the León cohort and 615 mothers (609 infants) from the Managua cohort were enrolled, of whom 622 children (303 from the León cohort; 319 from the Managua cohort) were included in the final analysis; four children had microcephaly at birth and thus were excluded from analyses, two from each cohort. 33 (11%) of 303 children enrolled in León and 219 (69%) of 319 children enrolled in Managua were exposed to Zika virus in utero. In both cohorts, no significant differences were identified in adjusted mean ELC scores between Zika virus-exposed and unexposed infants at 36 months (between-group difference 1·2 points [95% CI -4·2 to 6·5] in the León cohort; 2·8 [-2·4 to 8·1] in the Managua cohort) or at 48 months (-0·9 [-10·8 to 8·8] in the León cohort; 0·1 [-5·1 to 5·2] in the Managua cohort). No differences in ELC scores between Zika virus-exposed and unexposed infants exceeded 6 points at any time between 30 months and 48 months in León or between 36 months and 48 months in Managua, which was considered clinically significant in other settings. INTERPRETATION: We found no significant differences in neurodevelopmental scores between normocephalic children with in-utero Zika virus exposure and Zika virus-unexposed children at age 36 months or 48 months. These findings are promising, supporting typical neurodevelopment in Zika virus-exposed normocephalic children, although additional follow-up and research is warranted.

RESUMO

OBJECTIVE: To evaluate the prevalence, trends, and factors associated with psychotropic medication use and polypharmacy among children and adolescents initiating intensive behavioral therapy for severe challenging behavior over a 10-year period. STUDY DESIGN: In this retrospective observational study, we examined data from caregiver interviews and patient medical records on the number and types of psychotropic medications prescribed to patients initiating intensive behavioral therapy between January 1, 2013, and December 31, 2022. Trends in medication use and polypharmacy across the 10-year period were analyzed using regression analysis, while differences in demographics and clinical factors for patients with use and polypharmacy were analyzed using nonparametric statistical analysis with odds ratios presented for significant factors. RESULTS: Data from all 302 pediatric patients initiating intensive behavioral therapy across the 10-year period were analyzed. Among all patients and all years, 83.8% were taking at least 1 psychotropic medication and 68.2% experienced polypharmacy. There were no changes in the prevalence of use, mean number of medications taken, or polypharmacy across the 10-year period. Patients diagnosed with attention-deficit/hyperactivity disorder or anxiety disorder, as well as those exhibiting self-injurious behavior had higher use of psychotropic medication and polypharmacy and were taking more medications overall. CONCLUSIONS: Psychotropic medication use and polypharmacy were extremely high for children and adolescents with severe challenging behavior, but use and polypharmacy did not change over the 10-year period of data collection. Further research is needed to establish the generality of these findings to other regions of the US.

RESUMO

Community participation is a critical element in the management of Aedes aegypti and Aedes albopictus breeding sites. Many educational interventions have been conducted to encourage prevention and elimination of breeding sites among different community actors, such as government-run programs for vector surveillance aimed at preventing and eliminating breeding sites at the household level within a community. Getting people involved in prevention and elimination of vector breeding sites in their communities requires communication and social mobilization strategies to promote and reinforce those prevention actions that, in turn, should be effective from the entomological standpoint. Articles published in English, Spanish, and Portuguese, were reviewed to assess whether educational interventions targeting Ae. aegypti and Ae. albopictus were effective in reducing entomological indicators or in improving practices to prevent the presence of or eliminate breeding sites. The most widely used indicators were larval indices and the practices associated with reducing/eliminating breeding sites. We found that using a community-based approach adapted to eco-epidemiological and sociocultural scenarios explains the reduction of entomological indicators by educational interventions. Those who design or implement educational interventions should strengthen the evaluation of those interventions using qualitative approaches that provide a more complete picture of the social context and the barriers and facilitators to implementing vector control. Engaging school children in cross-sectorial collaboration involving the health and education spheres promotes the participation of the community in vector surveillance and reduces the risk of arboviral disease transmission.

RESUMO

HIV transmitted through cosmetic injection services via contaminated blood has not been previously documented. During summer 2018, the New Mexico Department of Health (NMDOH) was notified of a diagnosis of HIV infection in a woman with no known HIV risk factors who reported exposure to needles from cosmetic platelet-rich plasma microneedling facials (vampire facials) received at a spa in spring 2018. An investigation of the spa's services began in summer 2018, and NMDOH and CDC identified four former spa clients, and one sexual partner of a spa client, all of whom received HIV infection diagnoses during 2018-2023, despite low reported behavioral risks associated with HIV acquisition. Nucleotide sequence analysis revealed highly similar HIV strains among all cases. Although transmission of HIV via unsterile injection practices is a known risk, determining novel routes of HIV transmission among persons with no known HIV risk factors is important. This investigation identified an HIV cluster associated with receipt of cosmetic injection services at an unlicensed facility that did not follow recommended infection control procedures or maintain client records. Requiring adequate infection control practices and maintenance of client records at spa facilities offering cosmetic injection services can help prevent the transmission of HIV and other bloodborne pathogens and ensure adequate traceback and notification in the event of adverse clinical outcomes, respectively.

RESUMO

OBJECTIVE: Most prior research on physical activity (PA) and cognition is based on predominantly white cohorts and focused on associations of PA with mean (average) cognition versus the distribution of cognition. Quantile regression offers a novel way to quantify how PA affects cognition across the entire distribution. METHODS: The Kaiser Healthy Aging and Diverse Life Experiences study includes 30% white, 19% black, 25% Asian, and 26% Latinx adults age 65+ living in Northern California (n = 1600). The frequency of light or heavy PA was summarized as 2 continuous variables. Outcomes were z-scored executive function, semantic memory, and verbal episodic memory. We tested associations of PA with mean cognition using linear regression and used quantile regression to estimate the association of PA with the 10th-90th percentiles of cognitive scores. RESULTS: Higher levels of PA were associated with higher mean semantic memory (b = 0.10; 95% CI: 0.06, 0.14) and executive function (b = 0.05; 95% CI: 0.01, 0.09). Associations of PA across all 3 cognitive domains were stronger at low quantiles of cognition. CONCLUSION: PA is associated with cognition in this racially/ethnically diverse sample and may have larger benefits for individuals with low cognitive scores, who are most vulnerable to dementia.

RESUMO

BACKGROUND: Transgender women are disproportionately affected by both HIV and gender-based violence (GBV), defined as physical, sexual, or emotional violence perpetrated against an individual based on their gender identity/expression. While a growing body of evidence demonstrates that GBV leads to poor HIV care and treatment outcomes among cisgender women, less research has examined this association among transgender women. We assessed the impact of lifetime experiences of GBV on subsequent retention in HIV care and laboratory confirmed viral suppression among a sample of transgender women living with HIV (TWH) in Brazil. METHODS: A pilot trial of a peer navigation intervention to improve HIV care and treatment among TWH was conducted in São Paulo, Brazil between 2018 and 2019. TWH were recruited and randomized into the intervention or control arm and participated in a baseline and 9-month follow-up survey and ongoing extraction of clinical visit, prescribing, and laboratory data. Generalized linear model regressions with a Poisson distribution estimated the relative risk (RR) for the association of lifetime physical and sexual violence reported at baseline with treatment outcomes (retention in HIV care and viral suppression) at follow-up, adjusting for baseline sociodemographic characteristics. RESULTS: A total of 113 TWH participated in the study. At baseline, median age was 30 years, and the prevalence of lifetime physical and sexual violence was 62% and 45%, respectively. At follow-up, 58% (n = 66/113) were retained in care and 35% (n = 40/113) had evidence of viral suppression. In adjusted models, lifetime physical violence was non-significantly associated with a 10% reduction in retention in care (aRR: 0.90, 95% CI: 0.67, 1.22) and a 31% reduction in viral suppression (aRR: 0.69; 95% CI: 0.43, 1.11). Lifetime sexual violence was non-significantly associated with a 28% reduction in retention in HIV care (aRR: 0.72, 95% CI: 0.52, 1.00) and significantly associated with a 56% reduction in viral suppression (aRR: 0.44; 95% CI: 0.24, 0.79). CONCLUSION: Our findings are among the first to demonstrate that lifetime experiences with physical and sexual violence are associated with poor HIV outcomes over time among transgender women. Interventions seeking to improve HIV treatment outcomes should assess and address experiences of GBV among this population. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT03525340.

RESUMO

OBJECTIVE: To examine the longitudinal associations between newborn neurobehavioral stress signs, maternal parenting stress, and several indices of toddler language development. STUDY DESIGN: Participants include 202 mother-infant dyads (104 girls). We measured stress signs in neonates in the hospital at least 24 hours after birth using the Neonatal Intensive Care Unit Network Neurobehavioral Scale. At 7 months, parenting stress (competence, attachment, and role restriction) was assessed using the Parenting Stress Index. At 18 months, mothers completed the Communicative Development Inventories, which measured toddler gesturing, expressive vocabulary, and receptive vocabulary. Longitudinal path modeling was used to estimate associations between neonatal stress signs, parenting stress, and toddler language, and a model was generated for each language outcome. Child sex, birth weight, and family income were included as covariates. RESULTS: Infants who exhibited greater neurobehavioral stress signs at birth produced significantly fewer social-communicative gestures at 18 months of age. Among infants whose mothers reported low (but not high) levels of parenting stress during the first postnatal year, newborn stress signs were negatively associated with 18-month-olds' receptive vocabulary size. Neither newborn stress signs nor parenting stress were significantly related to toddler expressive vocabulary size. CONCLUSIONS: Our findings uncover a negative association between newborn stress signs and toddler gesturing. Furthermore, our results suggest that caregiver stress and neonatal stress signs interact to predict toddler receptive vocabulary. Taken together, these results demonstrate that some neonates who exhibit increased neurobehavioral stress signs may be at heightened risk for experiencing language difficulties. These children may benefit from additional support in infancy.

RESUMO

We performed an arboviral survey in mosquitoes from four endemic Ecuadorian cities (Huaquillas, Machala, Portovelo and Zaruma) during the epidemic period 2016-2018. Collections were performed during the pre-rainy season (2016), peak transmission season (2017) and post-rainy season (2018). Ae. aegypti mosquitoes were pooled by date, location and sex. Pools were screened by RT-PCR for the presence of ZIKV RNA, and infection rates (IRs) per 1,000 specimens were calculated. A total of 2,592 pools (comprising 6,197 mosquitoes) were screened. Our results reveal high IRs in all cities and periods sampled. Overall IRs among female mosquitoes were highest in Machala (89.2), followed by Portovelo (66.4), Zaruma (47.4) and Huaquillas (41.9). Among male mosquitoes, overall IRs were highest in Machala (35.6), followed by Portovelo (33.1), Huaquillas (31.9) and Zaruma (27.9), suggesting that alternative transmission routes (vertical/venereal) can play important roles for ZIKV maintenance in the vector population of these areas. Additionally, we propose that the stabilization of ZIKV vertical transmission in the vector population could help explain the presence of high IRs in field-caught mosquitoes during inter-epidemic periods.

RESUMO

ABSTRACT: We compared mpox vaccination access between urban and rural residents who received ≥1 JYNNEOS dose using immunization data in Idaho and New Mexico. Rural residents traveled 5 times farther and 3 times longer than urban residents to receive mpox vaccination. Increasing mpox vaccine availability to health care facilities might increase uptake.

RESUMO

Dengue, chikungunya, and Zika are arboviruses that cause 390 million infections annually. Risk factors for hospitalization are poorly understood. Communities affected by these diseases have an escalating prevalence of allergies and obesity, which are linked to immune dysfunction. We assessed the association of allergies or body mass with hospitalization for an arbovirus infection. From 2014 to 2017, we recruited participants with a clinical diagnosis of arbovirus infection. Arbovirus infections were laboratory-confirmed and allergies were self-reported. Mid-upper arm circumference (MUAC), weight, and height were measured. We used two logistic regression models to assess the relationships between hospitalization and allergies and between hospitalization and body mass (MUAC for participants <20 years old and body mass index (BMI) for adults ≥20 years old). Models were stratified by age group and adjusted for confounders. For allergies, 41 of 265 were hospitalized. There was no association between allergies and hospitalization. For body mass, 34 of 251 were hospitalized. There was a 43% decrease in hospitalization odds for each additional centimetre MUAC among children (aOR 0.566, 95% CI 0.252-1.019) and a 12% decrease in hospitalization odds for each additional BMI unit among adults (aOR 0.877, 95% CI 0.752-0.998). Our work encourages the exploration of the underlying mechanisms.

RESUMO

Glutaminase (GLS), which deaminates glutamine to form glutamate, is a mitochondrial tetrameric protein complex. Although inorganic phosphate (Pi) is known to promote GLS filamentation and activation, the molecular basis of this mechanism is unknown. Here we aimed to determine the molecular mechanism of Pi-induced mouse GLS filamentation and its impact on mitochondrial physiology. Single-particle cryogenic electron microscopy revealed an allosteric mechanism in which Pi binding at the tetramer interface and the activation loop is coupled to direct nucleophile activation at the active site. The active conformation is prone to enzyme filamentation. Notably, human GLS filaments form inside tubulated mitochondria following glutamine withdrawal, as shown by in situ cryo-electron tomography of cells thinned by cryo-focused ion beam milling. Mitochondria with GLS filaments exhibit increased protection from mitophagy. We reveal roles of filamentous GLS in mitochondrial morphology and recycling.

RESUMO

Introducción: El Sistema de Créditos Transferibles fue desarrollado para traducir la carga de trabajo de los estudiantes en créditos académicos que son reconocidos en todos los países, apuntando al logro del aprendizaje. El aprendizaje autónomo es un objetivo que la mayoría de los programas educativos promueven como una opción estratégica para conectar la profesión, el entorno de estudio y las expectativas profesionales. Objetivo: Analizar las horas de trabajo autónomo utilizadas por los estudiantes para lograr los resultados de aprendizaje determinados en los programas de asignaturas, su efectividad en cuanto al rendimiento académico y su correspondencia con lo establecido en el plan de estudio, ajustado al Sistema de Créditos Transferibles. Métodos: Se realizó un análisis descriptivo transversal retrospectivo a partir de datos de un registro manual de estudiantes (n = 54) y docentes (n = 6) respecto a seis asignaturas de primer nivel de la Carrera de Odontología de la Universidad Autónoma de Chile, sede Temuco. Resultados: Los análisis revelan una incoherencia entre las horas de trabajo autónomo utilizadas por los estudiantes con respecto a lo establecido en el plan de estudio y las horas de trabajo extra-aula estimadas por los profesores. Conclusión: Se concluye que la implementación del Sistema de Créditos Transferibles por sí sola no asegura una mejora en el desempeño de los estudiantes, requiriendo revisar el procedimiento institucional para definirlas; por parte de los docentes una mayor apropiación de los resultados de aprendizajes y la didáctica necesaria para orientar a los estudiantes a obtener un mayor rendimiento del trabajo autónomo, por otro lado, los estudiantes deben ser responsables del uso consciente de dichas horas(AU)


Introduction: The Transferable Credit System was developed to translate student workload into academic credits that are recognized in all countries, aiming at learning achievement. Autonomous learning is an objective that most educational programs promote as a strategic option to connect career, study environment and professional expectations. Objective: Analyzing the hours of autonomous work used by students to achieve the learning outcomes determined in the subject programs, their effectiveness in terms of academic performance and their correspondence with what is established in the study plan, adjusted to the Transferable Credit System. Methods: A retrospective cross-sectional descriptive analysis was carried out using data from a manual record of students (n= 54) and teachers (n= 6) regarding six first level subjects of the Dentistry course of the Universidad Autónoma de Chile, Temuco campus. Results: The analysis revealed an incoherence between the hours of autonomous work used by the students with respect to what is established in the study plan and the hours of extra-classroom work estimated by the professors. Conclusion: It is concluded that the implementation of the Transferable Credit System alone does not ensure an improvement in student performance, requiring a review of the institutional procedure to define them; on the part of teachers a greater appropriation of the learning outcomes and the didactics necessary to guide students to obtain a higher yield of autonomous work, on the other hand, students must be responsible for the conscious use of these hours(AU)

RESUMO

Abstract Introduction Head and neck lymphedema is an omnipresent morbidity related to head and neck cancer therapies. Studies on therapy for these patients in the acute postsurgical population have not been published to date. Objective To assess changes in the measurements of lymphedema in surgical head and neck cancer patients during the hospital stay with implementation of modified decongestive therapy (MDT). Methods Patients aged > 18 years undergoing neck dissection with or without primary-site resection or laryngectomy between 2016 and 2019 were included. Facial measurements were obtained prior to beginning MDT and again prior to discharge. A total facial composite measurement was calculated and used to assess change over time. Rates ≥ 2% of change were considered significant. Results A total of 38 patients were included (subsites: larynx = 27; thyroid =4; oral cavity = 3; and neck = 4). The mean number of days between surgery and the start of lymphedema therapy was 3.0 days. The mean number of days between measurements was 5.2 days. Reduction in the total composite score was observed in 37 (97%) patients, and 35 (92%) patients had a total composite reduction score > 2%. Tumor subsite and surgery type did not portend toward greater percent change, except for those patients treated with total laryngectomy, regional flap reconstruction, and neck dissection (p = 0.02). Conclusion Acute postsurgical inpatient MDT was associated with reduced total composite measurements in patients after head and neck surgery. As the first published study on lymphedema therapy in this acute postsurgical period, further prospective case-control studies are warranted to explore further benefits of acute therapy.

RESUMO

Introducción: Dentro de la cultura organizacional, el profesor universitario es un agente clave para el logro de los aprendizajes, coordinando diariamente las solicitudes de las asignaturas y carrera, junto a las necesidades estudiantiles. Por esto, la docencia es una de las profesiones con mayor riesgo de padecer estrés, así como ansiedad y depresión. Con el objetivo de disminuir dichos factores se han creado programas para docentes con diversas actividades que promueven el autocuidado. Objetivo: Demostrar la efectividad del Programa de Educación Meditativa del Sistema Isha Judd en la disminución de los niveles de estrés, depresión y ansiedad de docentes de la Facultad de Ciencias de la Salud de la Universidad Autónoma de Chile. Métodos: Se desarrollaron 10 talleres presenciales dirigidos por facilitadores del Sistema ISHA Judd. Los inscritos se dividieron en tres grupos que sesionaron los lunes, en horarios diferidos (n = 22). Las reuniones fueron cada 15 días, cada sesión se dividió en seis momentos. En la primera y última sesión se realizaron Test Depresión y Ansiedad de Beck, Escala de Autoestima de Rossemberg, Escala de Estrés Percibido y encuesta de bienestar del Sistema Isha Judd. Resultados: El nivel de estrés del grupo bajó en 7,2 puntos pasando de moderado a bajo, el nivel de depresión bajó significativamente, al igual que los valores de ansiedad, llegando a leve y mínimo. El nivel de autoestima inicialmente estaba en el rango alto y al finalizar se mantuvo en el mismo rango, pero mejorando el puntaje promedio en 1,88. Conclusión: En aquellos docentes que cumplieron con los requerimientos mínimos del programa, esta metodología impactó positivamente en su satisfacción, mejorando en promedio sus niveles de estrés, ansiedad, depresión y autoestima. Este estudio presenta limitaciones por el número y tipo de muestra por lo que se sugiere realizar una segunda etapa(AU)


Introduction: Within the organizational culture, the university professor is a key agent for the achievement of learning, coordinating daily the requests of the subjects and majors, together with the students' needs. For this reason, teaching is one of the professions with the highest risk of experiencing stress, as well as anxiety and depression. In order to reduce these factors, programs have been created for teachers with various activities that promote self-care. Objective: To demonstrate the effectiveness of the Meditative Education Program of the Isha Judd System in reducing the levels of stress, depression and anxiety in teachers of the School of Health Sciences of the Universidad Autónoma de Chile. Methods: Ten face-to-face workshops were conducted by facilitators of the Isha Judd System. The participants were divided into three groups that met on Mondays, at different times (n = 22). The meetings were held every 15 days, each session was divided into six moments. In the first and last session, Beck's Depression and Anxiety Test, Rossemberg's Self-Esteem Scale, Perceived Stress Scale and the Isha Judd System wellbeing survey were applied. Results: The stress level of the group decreased by 7.2 points, going from moderate to low, the depression level decreased significantly, as did the anxiety values, reaching mild and minimal. The level of self-esteem was initially in the high range and at the end it remained in the same range, but the average score improved by 1.88 points. Conclusion: In those teachers who met the minimum requirements of the program, this methodology had a positive impact on their satisfaction, improving on average their levels of stress, anxiety, depression and self-esteem. This study has limitations due to the number and type of sample, so a second stage is suggested(AU)

Methods Patients aged > 18 years undergoing neck dissection with or without primary-site resection or laryngectomy between 2016 and 2019 were included. Facial measurements were obtained prior to beginning MDT and again prior to discharge. A total facial composite measurement was calculated and used to assess change over time. Rates ≥ 2% of change were considered significant. Results A total of 38 patients were included (subsites: larynx = 27; thyroid = 4; oral cavity = 3; and neck = 4). The mean number of days between surgery and the start of lymphedema therapy was 3.0 days. The mean number of days between measurements was 5.2 days. Reduction in the total composite score was observed in 37 (97%) patients, and 35 (92%) patients had a total composite reduction score > 2%. Tumor subsite and surgery type did not portend toward greater percent change, except for those patients treated with total laryngectomy, regional flap reconstruction, and neck dissection ( p = 0.02). Conclusion Acute postsurgical inpatient MDT was associated with reduced total composite measurements in patients after head and neck surgery. As the first published study on lymphedema therapy in this acute postsurgical period, further prospective case-control studies are warranted to explore further benefits of acute therapy.

RESUMO

OBJECTIVE: To evaluate the association between consolidation on chest radiograph and typical bacterial etiology of childhood community acquired pneumonia (CAP) in the Etiology of Pneumonia in the Community study. STUDY DESIGN: Hospitalized children <18 years of age with CAP enrolled in the Etiology of Pneumonia in the Community study at 3 children's hospitals between January 2010 and June 2012 were included. Testing of blood and respiratory specimens used multiple modalities to identify typical and atypical bacterial, or viral infection. Study radiologists classified chest radiographs (consolidation, other infiltrates [interstitial and/or alveolar], pleural effusion) using modified World Health Organization pneumonia criteria. Infiltrate patterns were compared according to etiology of CAP. RESULTS: Among 2212 children, there were 1302 (59%) with consolidation with or without other infiltrates, 910 (41%) with other infiltrates, and 296 (13%) with pleural effusion. In 1795 children, at least 1 pathogen was detected. Among these patients, consolidation (74%) was the most frequently observed pattern (74% in typical bacterial CAP, 58% in atypical bacterial CAP, and 54% in viral CAP). Positive and negative predictive values of consolidation for typical bacterial CAP were 12% (95% CI 10%-15%) and 96% (95% CI 95%-97%) respectively. In a multivariable model, typical bacterial CAP was associated with pleural effusion (OR 7.3, 95% CI 4.7-11.2) and white blood cell ≥15 000/mL (OR 3.2, 95% CI 2.2-4.9), and absence of wheeze (OR 0.5, 95% CI 0.3-0.8) or viral detection (OR 0.2, 95% CI 0.1-0.4). CONCLUSIONS: Consolidation predicted typical bacterial CAP poorly, but its absence made typical bacterial CAP unlikely. Pleural effusion was the best predictor of typical bacterial infection, but too uncommon to aid etiology prediction.

RESUMO

A 17-y-old Rocky Mountain gelding was presented to the Virginia-Maryland Veterinary Teaching Hospital because of a 4-wk history of anorexia, weight loss, lethargy, and fever of unknown origin. Abdominal ultrasound revealed lymphadenomegaly of the abdominal and colonic lymph nodes, thickening of the wall of the large colon, and a mass associated with the large colon. The horse was euthanized given a poor prognosis. On autopsy, an ~20-cm diameter mass was found within the mesocolon between the right ventral and right dorsal colon. The mass had invaded through the colonic walls and formed a fistula between the 2 involved lumina. On histologic evaluation, the mass consisted of small numbers of large neoplastic lymphocytes, numerous small lymphocytes, and many foamy macrophages. A diagnosis of T-cell-rich, large B-cell lymphoma was made based on immunohistochemical staining for CD79a, CD3, and Iba1; concurrent infection with equid herpesvirus 5 was confirmed with in-situ hybridization (ISH). To our knowledge, neither a trans-colonic fistula resulting from alimentary lymphoma in a horse nor detection of intralesional equid herpesvirus 5 in equine alimentary lymphoma by ISH has been reported previously.
