Prolame produces anxiolytic- and antidepressant-like effects in middle-aged female rats with less uterotrophic effects than 17ß-estradiol.

Estrogen hormone replacement therapy (EHRT), improving women's life quality at menopause, reduces anxiety and depression symptoms associated with ovarian hormonal decline. However, its potential adverse effects, like thromboembolism and cancer risk, limit its use. Prolame is a synthetic 17ß-amino estrogen with antithrombotic actions that exerts anxiolytic- and antidepressant-like effects on young adult ovariectomized female rats. It is unknown if prolame's effects may be observed in age and endocrine conditions emulating menopause. This study aimed to identify the antidepressant- and anxiolytic-like effects of prolame and E2 (used as a reference estrogen treatment) in middle-aged female rats coursing with irregular cycles, in two different conditions: ovariectomized or gonadally intact. Results were compared with those from young adult ovariectomized rats. Prolame (60 or 120 µg/kg), 17ß-estradiol (E2, 40 or 80 µg/kg), or vehicle were chronically administered, and their effects were evaluated in the elevated plus-maze, defensive burying behavior test, open field test, and forced swimming test. Uterotrophic actions were estimated by uterine weight related to body weight. Prolame and E2 produced robust anxiolytic- and antidepressant-like effects in young adult ovariectomized rats, but these effects were absent in gonadally intact middle-aged rats. Interestingly, only prolame induced anxiolytic- and antidepressant-like effects in middle-aged ovariectomized rats. Uterotrophic effects of prolame were weaker than E2 effects, notably in middle-aged females. Altogether, present data support the notion that prolame has the potential to be considered an EHRT with relevant psychoactive actions and with apparently lower adverse-side effects, especially in middle-aged populations.

Bilingüismo y lenguaje en niños con trastorno del espectro autista: una revisión sistemática / Bilingualism and language in children with autistic spectrum disorder: a systematic review

Introducción La comunicación y el lenguaje de las personas con trastorno del espectro autista (TEA) son algunos de los aspectos que más frecuentemente se ven alterados en este trastorno del neurodesarrollo. Cuando un niño que recibe el diagnóstico de TEA vive en un entorno bilingüe, los padres con frecuencia manifiestan su preocupación sobre si sus hijos deberían aprender dos idiomas simultáneamente y acuden a especialistas para ser aconsejados al respecto. A pesar de que no exista evidencia de sus efectos negativos, algunos profesionales se han mostrado en desacuerdo. Este trabajo pretende conocer si el bilingüismo afecta al lenguaje de niños con TEA. Desarrollo Se ha realizado una revisión de la literatura científica publicada en cuatro bases de datos y siguiendo una serie de criterios se han seleccionado 12 artículos publicados en revistas científicas. Participaron 328 niños diagnosticados con TEA (169 bilingües y 159 monolingües) con edades entre los 3 y 12 años, evaluados con diferentes pruebas de lenguaje receptivo y expresivo que abarcan áreas diversas. La evaluación se realizó de modo directo a los niños, aunque también se evaluaron indirectamente a los padres en algunos trabajos. Conclusiones Se ha comprobado en esta revisión que existe acuerdo sobre que el bilingüismo no supone ninguna dificultad adicional para el desarrollo del lenguaje de niños con TEA a partir de los 3 años.

Introduction Communication and language skills are among the most severely affected domains in individuals with autistic spectrum disorder (ASD). When a child diagnosed with ASD lives in a bilingual environment, the parents often express concerns about whether their child should learn both languages simultaneously, turning to specialists for advice. Despite the lack of evidence of any negative effect, some professionals disagree on this subject. In this systematic review we study whether bilingualism affects language development in children with ASD. Methods We reviewed the literature published in 4 different databases. After applying a series of selection criteria, we selected 12 scientific articles, including a total of 328 children diagnosed with ASD (169 bilingual and 159 monolingual), with ages ranging from 3 to 12 years. These patients were evaluated with different receptive and expressive language assessment instruments covering several areas. The assessments were performed directly on the children, although indirect assessment of parents was also performed in some studies. Conclusions There seems to be consensus regarding the assertion that bilingualism does not entail any additional difficulty for language development in children with ASD from the age of 3. (AU)

Cuantificación absoluta de la captación miocárdica de 99mTc-DPD en pacientes con amiloidosis cardiaca por depósitos de transtiretina (ATTR) / Absolute quantification of myocardial uptake of 99mTc-DPD in patients with cardiac amyloidosis due to transthyretin deposits (ATTR)

Objetivo Determinar la contribución diagnóstica de la cuantificación absoluta del depósito miocárdico de 99mTc-DPD en pacientes con amiloidosis cardiaca por depósitos de transtiretina (ATTR). Materiales y métodos Se realizó SPECT/TC a 41 pacientes con resultado gammagráfico positivo para amiloidosis cardiaca ATTR. Se dividió a los pacientes en dos grupos (grados2 y3 de Perugini) y se calcularon los SUVmax a nivel del hueso y de ambos ventrículos y el porcentaje de dosis calculado en estas áreas. Se empleó la prueba t de Student para comparar resultados y se calculó el área bajo la curva (AUC) para evaluar la eficacia diferencial y establecer unos puntos de corte discriminatorios entre ambos grupos de pacientes. Resultados Se observaron diferencias estadísticamente significativas en todas las variables a estudio, a excepción del SUVmax hueso. Las diferencias con mayor potencia estadística se observaron en las variables SUVmaxVD y el porcentaje de dosis en ambos ventrículos (p<0,001). El punto de corte obtenido para la variable SUVmaxVI fue de 8,620 (sensibilidad del 87,9% y especificidad del 100%; AUC: 0,966), mientras que el de la variable SUVmaxVD fue de 6,195 (sensibilidad del 81,8% y especificidad del 100%; AUC: 0,955). Conclusiones La cuantificación absoluta de la captación miocárdica de 99mTc-DPD en las imágenes SPECT/TC de pacientes con sospecha de amiloidosis cardiaca por depósitos de transtiretina supone una nueva herramienta diagnóstica que permite una adecuada clasificación de los pacientes, acorde a la escala de gradación visual de Perugini (AU)

Purpose To determine the diagnostic contribution of the absolute quantification of the myocardial deposit of 99mTc-DPD in patients with cardiac amyloidosis due to transthyretin deposits (ATTR). Materials and methods SPECT/CT was performed on 41 patients with positive scintigraphic results for ATTR cardiac amyloidosis. The patients were divided into two groups (Perugini grades2 and3) and the SUVmax at the level of the bone and both ventricles and the percentage of dose calculated in these areas were calculated. Student's t-test was used to compare results and the area under the curve (AUC) was calculated to assess differential efficacy and establish discriminatory cut-off points between both groups of patients. Results Statistically significant differences were observed in all the study variables, with the exception of SUVmax bone. The differences with the greatest statistical power were observed in the variables SUVmaxRV and the percentage of dose in both ventricles (P<.001). The cut-off point obtained for the variable SUVmaxLV was 8.620 (sensitivity 87.9% and specificity 100%; AUC: 0.966), while that of the variable SUVmaxRV was 6.195 (sensitivity 81.8% and specificity 100%; AUC: 0.955). Conclusions The absolute quantification of myocardial uptake of 99mTc-DPD in the SPECT/CT images of patients with suspected cardiac amyloidosis due to transthyretin deposits represents a new diagnostic tool that allows an adequate classification of patients, according to the visual grading scale of Perugini (AU)

La disfagia en cuidados intensivos, un problema real: análisis de factores de riesgo / Dysphagia in intensive care, a real problem: analysis of risk factors

Objetivos: Determinar los factores de riesgo presentes en los pacientes con disfagia en relación con una población de pacientes críticos. Método: Serie de casos de una cohorte de pacientes reclutados en la unidad de cuidados intensivos (UCI) hasta el alta hospitalaria. Se reclutaron a aquellos pacientes que dieron su consentimiento y cumplían los criterios de inclusión. El método de exploración clínica Volumen-Viscosidad fue utilizado para la detección de la disfagia. Se realizó un análisis estadístico uni- y bivariante, a través del odds ratio (OR) para detectar los factores de riesgo en la disfagia. Resultados: 103 pacientes fueron reclutados de 401 posibles. La media de edad fue de 59,33±13,23; los hombres representaban el 76,7%. La gravedad media fue: APACHE II (12,74±6,17) y Charlson (2,98±3,31). Un 45,6% de los pacientes desarrollaron disfagia, obteniendo valores significativos de OR (p<0,050) para el desarrollo de disfagia: la mayor edad, los antecedentes neurológicos, COVID19, la alta estancia en UCI y hospitalización y la presencia de traqueotomía. Los pacientes COVID19 representaban el 46,6%, por lo que se realizó un análisis de este subgrupo observando resultados similares, con un riesgo de Charlson (OR:4,65; IC95%: 1,31-16,47; p=0,014) y una estancia hospitalaria (OR: 8,50; IC95%: 2,20-32,83; p<0,001). Al alta de UCI, el 37,9% de la población presentaba todavía disfagia, y mantenía este problema al alta hospitalaria el 12,6%. Conclusiones: Casi la mitad de nuestros pacientes presentaron disfagia. Fueron factores de riesgo la gravedad clínica y la presencia de traqueotomía. Se observó en estos pacientes una mayor estancia tanto en UCI como en hospitalización.(AU)

Aims: To identify risk factors present in patients with dysphagia in a population of critically ill patients. Methods: Case series of a cohort of patients recruited in the intensive care unit (ICU) until hospital discharge. Patients who gave consent and met the inclusion criteria were recruited. The Volume-Viscosity clinical examination method was used for the screening of dysphagia. An uni- and bivariate statistical analysis was performed using odds ratio (OR) to detect risk factors for dysphagia. Outcomes: 103 patients were recruited from 401 possible. The mean age was 59,33±13,23, men represented 76,7%. The severity of the sample was: APACHE II (12,74±6,17) and Charlson (2,98±3,31). 45,6% of patients showed dysphagia, obtaining significant OR values (p<0,050) for the development of dysphagia: older age, neurological antecedents, COVID19, long stay in ICU and hospitalization, and the presence of tracheotomy. COVID19 patients represented 46,6% of the sample, so an analysis of this subgroup was performed, showing similar results, with a Charlson risk (OR:4,65; 95% CI:1,31-16,47; p=0,014) and a hospital stay (OR: 8,50; 95%CI: 2,20-32,83; p<0,001). On discharge from the ICU, 37,9% of the population still had dysphagia; 12,6% maintained this problem at hospital discharge. Conclusions: Almost half of our patients developed dysphagia. Clinical severity and the presence of tracheotomy were risk factors. We observed in patients with dysphagia a longer stay in both ICU and hospitalization.(AU)

Central nervous system activity of a Tabernaemontana arborea alkaloid extract involves serotonergic and opioidergic neurotransmission in murine models.

Tabernaemontana arborea (Apocynaceae) is a Mexican tree species known to contain ibogan type alkaloids. This study aimed at determining central nervous system-related activities of an alkaloid extract obtained from the root bark of T. arborea. A gas chromatography-mass spectrometry (GC-MS) analysis was performed to describe the alkaloid profile of the extract. A wide dosing range (0.1 to 56.2 mg/kg) of this extract was evaluated in different murine models. Electrical brain activity was examined by electroencephalography (EEG). The extract's effects on motor coordination, ambulatory activity, and memory were analyzed based on the rotarod, open field (OFT), and object recognition tests (ORT), respectively. Antidepressant and antinociceptive activities were determined using the forced swimming test (FST) and the formalin assay, respectively. In order to elucidate the underlying mechanisms of action, the 5-HT1A receptor antagonist WAY100635 (1 mg/kg) or the opioid receptor antagonist naloxone (1 mg/kg) was included in the latter experiments. GC-MS analysis (µg/mg extract) confirmed the presence of the monoterpenoid indole alkaloids (MIAs) voacangine (207.00), ibogaine (106.33), vobasine (72.81), coronaridine (30.72), and ibogamine (24.2) as principal constituents of the extract, which exhibited dose- and receptor-dependent antidepressant (0.1 to 1 mg/kg; 5-HT1A) and antinociceptive (30 and 56.2 mg/kg; opioid) effects, without altering motor coordination, ambulatory activity, and memory. EEG indicated CNS depressant activity at high doses (30 and 56.2 mg/kg). The root bark of T. arborea contains a mixture of alkaloids that may hold therapeutic value in pain relief and the treatment of psychiatric diseases without causing neurotoxic activity at effective doses.

Usefulness of Community Pharmacy for Early Detection of Cognitive Impairment in Older People Using the IQ-CODE Questionnaire.

BACKGROUND: People with cognitive impairment (CI) need to be identified early because of the risk of progression to dementia. OBJECTIVES: The primary objective of the study was to analyze the usefulness of the community pharmacy for early detection of CI in older people through their caregivers. As secondary objective the risk factors related to IQ-CODE classification of risk of CI were identified. DESIGN: A cross-sectional observational study was designed. SETTING: Caregivers were selected by pharmacists from Spanish community pharmacies. PARTICIPANTS: Subjects with a close relationship to persons over 70 years of age who were not previously diagnosed with CI and who did not live in a nursing home or were hospitalized participated in the study. MEASUREMENTS: The proportion of older people who were classified as "at risk of CI" was assessed using the Informant Questionnaire on Cognitive Decline in the Elderly (IQ-CODE), which was completed by the caregiver. RESULTS: A total of 197 pharmacists selected 910 caregivers with an average age of 53 years, 75.5% of whom were women. In 324 people over the age of 70 (38.5%), "risk of CI" was observed, increasing with age. The risk of CI was 4.3 times higher in older people who complained of memory loss (p<0.001), 2.5 times higher if they had had a stroke in the last two years (p=0.007), 1.9 times higher if they were smokers (p=0.045) and 1.6 times higher if they were diabetic (p=0.028). CONCLUSION: Detection of risk of CI from the community pharmacy showed prevalence figures consistent with the CI figures observed in the Spanish primary care setting, demonstrating the capacity of the community pharmacy to contribute to early detection of CI.

Neumoencéfalo, coma y convulsiones después de una cirugía de descompresión lumbar / Pneumocephalus, coma and seizures following lumbar decompression surgery

Describimos un caso de neumoencéfalo en una paciente con estenosis de canal medular por espondilolistesis degenerativa tras cirugía de descompresión lumbar. El caso comienza en el momento del despertar de la anestesia, en el que la paciente presenta bajo nivel de consciencia, sin respuesta de apertura ocular, ninguna respuesta verbal y la respuesta motora sOlo retira en respuesta al dolor (Glasgow 7), que precisa ingreso en la unidad de cuidados intensivos para ventilación mecánica. Posteriormente la paciente experimentó una crisis convulsiva tónico-clónica generalizada, por lo que se realizó una tomografía computarizada (TC) donde se observa un neumoencéfalo voluminoso con un efecto ocupante de espacio en los lóbulos frontal y parietal, los ventrículos laterales y la cisterna.Se inició terapia antiepiléptica (diazepam y levetiracetam) y vigilancia neurológica. A las 12h postoperatorias, la TC repetida demostró que el neumoencéfalo había mejorado persistiendo una cantidad mínima que Solo se limitaba al lóbulo frontal. La consciencia persistía severamente disminuida. El electroencefalograma mostró actividad epileptiforme continua y la adicción de fenitoína continua intravenosa al tratamiento antiepiléptico previo consigue mejorar gradualmente el nivel de consciencia y las respuestas motoras y verbales. A las pocas horas, la paciente fue extubada y no presentó déficits neurológicos posteriores. El neumoencéfalo debe considerarse en el diagnóstico diferencial cuando se evalúa a un paciente con un estado mental alterado después de una cirugía lumbar.(AU)

We describe a patient with pneumocephalus following lumbar decompression surgery who presented altered mental status at time to awake of anesthesia and the patient was admitted in intesive care unit in mechanical ventilation. The patient has not eye-opening response, no verbal response and motor response only withdraw in response to pain (7 points on Glasgow coma scale). Then, the patient experienced a generalized tonic-clonic seizure. Immediate cranial computed tomography (CT) images were performed. Cerebral pneumocephalus was present in CT, imaging revealed a voluminous pneumocephalus responsible for a significantspace-occupying effect on the frontal and parietal lobes, lateral ventricles and quadrigeminal plate cistern.Anti-epileptic therapy (diazepam and levetiracetam) and neurological monitoring were initiated. At 12 postoperative hours repeat CT scanning showed pneumocephalus were completely improved to minimal quantity and only limited to frontal lobe. The consciousness is impaired, and a generalized tonic-clonic seizure was present. Electroencephalogram showed continuous epileptiform activity and phenytoin IV was administered in continuous infusión. Four hours later the level of consciousness gradually improved, and the patient was right in eye opening, verbal and motor responses. A few hours later the patient was extubated, and no neurological deficits were present. Pneumocephalus should be considered in the differential diagnosis when evaluating a patient with altered mental status following lumbar surgery.(AU)

Language Barriers in Organismal Biology: What Can Journals Do Better?

In the field of organismal biology, as in much of academia, there is a strong incentive to publish in internationally recognized, highly regarded, English-language journals to promote career advancement. This expectation has created a linguistic hegemony in scientific publishing, whereby scholars for whom English is an additional language face additional barriers to achieving the same scientific recognition as scholars who speak English as a first language. Here, we surveyed the author guidelines of 230 journals in organismal biology with impact factors of 1.5 or greater for linguistically inclusive and equitable practices and policies. We looked for efforts that reflect first steps toward reducing barriers to publication for authors globally, including the presence of statements that encouraged submissions from authors of diverse nationalities and backgrounds, policies regarding manuscript rejection based on perceived inadequacies of the English language, the existence of bias-conscious reviewer practices, whether translation and editing resources or services are available, allowance for non-English abstracts, summaries, or translations, and whether journals offer license options that would permit authors (or other scholars) to translate their work and publish it elsewhere. We also directly contacted a subset of journals to verify whether the information on their author guidelines page accurately reflects their policies and the accommodations they would make. We reveal that journals and publishers have made little progress toward beginning to recognize or reduce language barriers. Counter to our predictions, journals associated with scientific societies did not appear to have more inclusive policies compared to non-society journals. Many policies lacked transparency and clarity, which can generate uncertainty, result in avoidable manuscript rejections, and necessitate additional time and effort from both prospective authors and journal editors. We highlight examples of equitable policies and summarize actions that journals can take to begin to alleviate barriers to scientific publishing.

ResumenEn el campo de la biología organísmica, al igual que en el mundo académico en general, existe un gran incentivo para publicar en revistas científicas de lengua inglesa que son reconocidas internacionalmente y que poseen gran prestigio con el fin de avanzar profesionalmente. Esta expectativa ha creado una hegemonía lingüística en la publicación científica en la que los académicos para quienes el inglés es una lengua adicional se enfrentan a barreras adicionales para lograr el mismo reconocimiento científico que los académicos que hablan inglés como primera lengua. En este estudio examinamos las instrucciones para autores de 230 revistas de biología organísmica con Factor de Impacto igual o superior a 1.5 en busca de prácticas y políticas lingüísticamente inclusivas y equitativas. Buscamos iniciativas que reflejen pasos iniciales hacia la reducción de barreras de publicación para autores a nivel mundial. Estas incluyen la presencia de anuncios que incentiven el envío de trabajos por autores de diversas nacionalidades, políticas relacionadas al rechazo de manuscritos debido a la percepción de insuficiencias en el inglés, prácticas de revisión conscientes de prejuicios, disponibilidad de recursos o servicios de traducción y edición, la publicación de resúmenes o traducciones en idiomas adicionales al inglés y la disponibilidad de licencias que permitan a los autores (u otros académicos) traducir su trabajo y publicarlo en otro lugar. También contactamos directamente a un subconjunto de revistas para comprobar si la información que aparece en las instrucciones para autores refleja con exactitud sus políticas y los ajustes que harían. Comprobamos que las revistas y los editores han avanzado poco en el reconocimiento o reducción de barreras lingüísticas y en la promoción de igualdad lingüística. Al contrario de nuestras predicciones, las revistas asociadas a sociedades científicas no parecen tener políticas más inclusivas en comparación con las revistas que no pertenecen a ninguna sociedad. Muchas políticas carecen de transparencia y claridad, lo que puede generar incertidumbre, dar lugar a rechazos evitables de manuscritos y exigir tiempo y esfuerzo adicionales tanto a los futuros autores como a los editores de las revistas. También destacamos ejemplos de políticas equitativas y resumimos las medidas que las revistas pueden adoptar para empezar a aliviar los obstáculos de publicación científica.

概要生物学の分野では、他の多くの学術分野と同様、国際的に認知され高い評価を得ている英文学術誌で論文を発表し、キャリアアップを図ろうという強い動機付けが存在する。このため、英語が母語でない研究者は、英語を母語とする研究者と同等の評価を得るために、さらなる障壁に直面するという問題が生じている。本研究では、インパクトファクターが1.5以上の生物学分野の雑誌230誌を対象に、言語的にどれだけ包括的で公平な方針をもっているか、著者ガイドラインを調査することで明らかにした。多様な国籍や背景を持つ著者からの投稿を奨励する記述の有無、英語力の不足を原因とする原稿のリジェクトに関する方針、偏見に配慮した査読方針、翻訳·ãƒ»ç·¨é›†ãƒªã‚½ãƒ¼ã‚¹ã‚„サービスの有無、英語以外の要旨・や本文の許容、著者 (または他の研究者) が自分の原稿を翻訳して別途出版できるようなライセンス条項を雑誌に設けているかなど、論文出版に対する障壁を減らすための第一歩となる取り組みに着目した。また、一部の雑誌には直接連絡を取り、著者のためのガイドラインのページに記載されている情報が、雑誌の方針と対応策を正確に反映しているかどうかを確認した。その結果, 学術誌や出版社は、言語の障壁を認識したり軽減したりするためにほとんど取り組みを行っていないことが明らかになった。我々の予想に反して, 学会に属する雑誌は、学会に属さない雑誌と比較して、より言語的に包括的な方針を持っていないようであった。これらの雑誌の多くの方針は透明性と明瞭性を欠いており、不確実性を生み出し、避けることのできる原稿のリジェクトを招き、執筆者と雑誌編集者の両方にさらなる時間と労力を必要とさせる可能性がある。本稿では、言語的に公平な方針の例を紹介し, 科学出版に対する障壁を軽減するために学術雑誌が取ることのできる行動を要約した.
