Authors: Ricardo Salcedo Hugo , Fitha M Vasquez , Mariana Lalaleo Elvia
Published: March 2022

To report the use of intravitreal dexamethasone implant and its short-term efficacy in a pediatric patient with Coats' disease. A 7-year-old patient was referred to the clinic because of decreased visual acuity in the right eye of 10-month duration. Best-corrected visual acuity was 20/400. Funduscopic examination showed evidence of Stage 2B Coats' disease. The patient underwent treatment with laser photocoagulation, intravitreal injection of bevacizumab, and intravitreal injection of dexamethasone implant. During the 10-month follow-up, there was no evidence of side effects. Anatomical resolution was evident on funduscopic examination and macular optical coherence tomography, with best-corrected visual acuity being 20/60. Intravitreal dexamethasone implant was effective during the 10-month follow-up; providing improvement in visual acuity without any side effects.

Published: March 2022

Background:

Coronavirus disease-2019 has rapidly spread globally and has become a global public health crisis. Obesity is the most frequent comorbidity exhibited by severe acute respiratory syndrome coronavirus-2. Many studies have highlighted the benefits of prone position (PP) with high flow nasal oxygenation (HFNC) in patients with moderate to severe acute respiratory distress syndrome (ARDS). This further delay intubation, reduce intensive care unit (ICU) stay and decreases overall morbidity.

Methods:

In this study, we analyzed case record data of morbidly obese patients (body mass index >35Kg/m2) with moderate-to-severe ARDS over 3 months. We evaluated the efficacy of early application of PP with HFNO in morbidly obese patients with moderate-to-severe COVID-19 ARDS on PaO2/FiO2 ratio.

Results:

A total of 24 morbidly obese patients were included in the study. Patients were divided into two groups: Group F (those who were intubated) and Group S (who did not require invasive mechanical ventilation). One hour of PP along with the use of HFNO, the P/F ratio was significantly higher in Group S (78.23 ± 7.16) than in Group F (63.58 ± 15.40) (P < 0.05). The ICU stay was longer in patients who required invasive mechanical ventilation, 17.33±2.52 days in Group F as compared to 8.11±1.05 days in Group S.

Conclusion:

PP with HFNO seems safe in morbidly obese patients and may improve oxygenation more than in nonobese patients. It is important to stress the necessity to start out postural treatment as early because the patient's clinical condition permits. PP with HFNO might avoid tracheal intubation and its inherent risks and prove beneficial in resource-limited scenarios.
Effect of nitrous oxide and dexmedetomidine on the consumption of propofol during general anesthesia in adult patients
Authors: Biyani Ghansham , Bhatia Pradeep Kumar , Mohammed Sadik , Bihani Pooja , Kamal Manoj , Chhabra Swati
Published: March 2022

Background:

Use of both nitrous oxide and dexmedetomidine as anesthetic adjuvants has shown to reduce the consumption of propofol required for the maintenance of anesthesia. The present study evaluated these two agents for their propofol sparing effect which has not been compared so far.

Materials and Methods:

Sixty adult patients undergoing elective surgery were enrolled and randomly divided into three groups. Patients in group P received propofol started at 166 μg/kg/min and then titrated to maintain the Bi-Spectral Index (BIS) value between 40 and 60, while patients in group N and in group D received nitrous oxide as carrier gas and infusion of dexmedetomidine (1 μg/kg over 10 min followed by 0.5 μg/kg/h) respectively, in addition to propofol. Primary outcome of the study was total consumption of propofol. Secondary outcomes measured were intraoperative hemodynamics, recovery profile, residual sedation, rescue analgesic requirements, and relevant side effects.

Results:

Total consumption of propofol was significantly higher in group P (139.02 ± 65.24 μg) compared to group N (94.72 ± 48.04 μg) and group D (98.31 ± 39.45 μg) (mean difference [95% confidence interval] group P and N 44.3 [17.9–44.7]; group P and D 40.71 [26.0–52.8]; group N and D 3.59 [−5.3–21.5]) (P = 0.015). Although the recovery parameters (time to extubation, time to achieve BIS of 90, and time to verbal commands) were significantly prolonged in group D (P < 0.001), time to discharge from postanesthesia care unit (PACU) was comparable among all groups (P = 0.65). When arrived in PACU, patients in group D were significantly more sedated (P = 0.0005) however, the 30 min in PACU the difference was nonsignificant. None of the patients in group D had nausea and vomiting and did not require additional analgesics.

Conclusion:

Both nitrous oxide and dexmedetomidine significantly decreased the total consumption of propofol. Hence, both these agents can be used as potential anesthetic adjuvants to decrease the side effects associated with propofol infusion. Due to the lack of any reported environmental and long-term side effects, dexmedetomidine can be a safer and better alternative to nitrous oxide.
Ultrasound versus palpation method for accurate estimation of intervertebral space
Authors: Seetha Ammu , Varughese Silvy Anna
Published: March 2022

Background and Aims:

Spinal cord injury resulting from the central neuraxial blockade is a rare but dreadful complication. The most likely cause is believed to be misjudged level of the intervertebral space (IVS). In our study, we assessed the accuracy of IVS marked by the anesthesiologist in 170 patients who were posted for surgery under spinal anesthesia using ultrasonography.

Methodology:

This was a prospective examiner-blinded observational study in 170 patients. An anesthesiologist estimated and marked the IVS using conventional palpation method (based on intercristal line), and the level was counterchecked ultrasonically by another anesthesiologist, who was blinded to the initial marked level.

Statistical Analysis:

The agreement between the palpation method and ultrasound assessment of IVS was analyzed using the Chi-square test. P < 0.05 was considered statistically significant.

Results and Conclusion:

The IVS estimated by conventional palpation method correlated with ultrasound estimation in only 49.4% of patients.
Preprocedural ultrasound assessment of landmarks of paramedian approach for subarachnoid block in geriatric population
Authors: Ray Tapan Kumar , Saxena Shlok , Panda Amrita
Published: March 2022

Background

: Paramedian spinal anesthesia is the preferred anesthetic technique in the elderly. This conventional approach is occasionally challenged by difficulty in identifying landmarks accurately. Neuraxial ultrasound aims to overcome these inaccuracies.

Objective

: The objective was that the routine use of preprocedural ultrasound assessment of landmarks for paramedian spinal in geriatric population improves the efficacy of spinal anesthesia by reducing the number of attempts and redirections.

Materials and Methods

: Sixty consenting elderly patients aged 60 year or above, posted for elective surgery under spinal anesthesia, were enrolled in the study. Participants were assigned at random to receive spinal anesthesia by the paramedian approach by either conventional landmark guidance (Group CP) or preprocedural ultrasound-assisted (Group PP) technique.

Results

: The number of needle redirections was not significant and the success rate at the first attempt with no redirection was higher in the ultrasound compared with the landmark group. However, the mean insertion attempts were indifferent. The preprocedural ultrasound-assisted approach required an insignificantly shorter time for administering spinal anesthesia than the landmark-guided technique (48.87s [67.65] vs. 50.67s [50.19]) [P = 0.90]. The periprocedural pain scores (2.90[2.07] vs. 2.87[1.57]) [P = 0.94] and willingness for a similar future intervention (66.7 vs. 66.7%) were comparable among the groups.

Conclusion:

The use of preprocedural ultrasonography for paramedian approach to spinal anesthesia is not superior to the conventional landmark guidance in achieving successful dural tap at L3-L4 interspace in elderly adult population and should be limited to a setting with expert operators and selected patients for whom conventional methods may be technically challenging.
Generalized Gaussian bounds for discrete convolution powers
Authors: Coulombel Jean-François , Faye Grégory
Published: March 2022

We prove a uniform generalized Gaussian bound for the powers of a discrete convolution operator in one space dimension. Our bound is derived under the assumption that the Fourier transform of the coefficients of the convolution operator is a trigonometric rational function, which generalizes previous results that were restricted to trigonometric polynomials. We also allow the modulus of the Fourier transform to attain its maximum at finitely many points over a period.
Endoscopic grading systems for nasal polyps: are we comparing apples to oranges?
Authors: Djupesland P.G. , Reitsma S. , Hopkins C. , Sedaghat A.R. , Peters A. , Fokkens W.J.
Published: March 2022

Endoscopic grading of nasal polyps (NP) is typically a coprimary endpoint in clinical trials evaluating treatments for chronic rhinosinusitis with nasal polyps (CRSwNP). However, a consensus on the most effective way to grade nasal polyps has not been reached. Different scales have been used, hampering the interpretation of data across trials. This review compares the characteristics of NP grading systems used in registration trials for approved NP treatments. These fundamental differences in grading systems make quantitative comparison of outcomes between trials inaccurate and potentially misleading. In lieu of a universal grading system, reporting the baseline distribution of polyp grades (unilateral and/or summed/total grades), as well as changes from baseline over time by baseline grade may help improve interpretability of outcomes and reduce inaccuracy when attempting cross-trial comparisons and making therapeutic decisions.

Published: March 2022

Background: Dermoid cyst accounts for 10-20 % of all ovarian tumors. Traditionally giant ovarian cysts have been removed through a midline laparotomy. Here we report a case of laparoscopy-assisted removal of a giant dermoid cyst in an adolescent girl.
Case Presentation: A 17-year-old girl presented with a complaint of abdominal distension for 7 months. Abdominal examination revealed a well-defined tense cystic mass arising from the pelvis and extending up to the epigastric region. CT scan of abdomen and pelvis reported a mature teratoma of size 25.5x19.9x35cm of the right ovary. Laparoscopic excision of the cyst was performed following extracorporeal drainage of the cyst.
Conclusion: Laparoscopy-assisted of a giant ovarian dermoid cyst is a feasible mode of treatment irrespective of its size provided malignancy has been ruled out.

The investigation revealed pneumomediastinum, pneumorachis, and soft tissue density in the left bronchus. The child underwent rigid bronchoscopy and retrieval of an organic foreign body.
Conclusion: Acute exogenous lipoid pneumonia can occur in children because of aspiration of oil-secreting organic foreign body. The presentation can be atypical, clinical suspicion and early diagnosis with timely intervention are crucial for the appropriate management.
Obrazovanje osuđenika – od resocijalizacije do transformacije –
Authors: Ilijić Ljeposava
Published: March 2022

U monografiji je predstavljen jedan kompleksan pogled na obrazovni tretman u zatvorima, u kojem se složenost i delikatnost teme obrazovanja osuđenika analizira se u kontekstu savremenih zatvorskih sistema i savremene pedagogije, kao i neophodnosti „rehabilitovanja rehabilitacije“ kao cilja i kao suštine zatvorske kazne i tretmana. Od naslova do zaključka, prepliću se prikazi društvenih vizija o obrazovanju u zatvoru koji su bili dominantni u periodu popravljanja i resocijalizacije, sa vizijama i očekivanjima „šta treba kod osuđenika da koriguje” obrazovni tretman danas, kao dominantan diskurs poslednjih decenija. U Uvodnim poglavljima, navodi se značaj i uloga koju ima obrazovni tretman u zatvorima, zašto je važno sprovođenje obrazovnih tretmana, kakva je motivacija osuđenika za uključivanje u obrazovne sadržaje i koji su razlozi za neuključenost u iste, posebno naglašavanje svih složenosti zatvorskog konteksta, kao okruženja u kojem se odvija proces obrazovanja u zatvorima. Posebni poglavlje posvećeno je Pravu osuđenika na obrazovanje uz analizu preporuke Evropske komisije o obrazovanju u zatvorima. Polazeći od ovog bazičnog, važnog dokumenta usvojenog na globalnom nivou, autorka prikazuje na koja su se naučna istraživanja oslanjale Preporuke usvojene 1989. godine i koji su najveći izazovi u praktičnoj primeni ovih načela, nekada i danas. Takođe, u monografiji se analiziraju i revidirane Preporuke Evropske komisije iz 2019. godine i ističe značaj implementacije savremenih naučnih istraživanja o patnjama u zatvoru i načinima na koji ih obrazovni tretmani mogu ublažiti. Autorka primećuje da su revidirane Preporuke uvažile potrebu za implementacijom savremenih tehnologija u obrazovne procese, ali i potrebu da ono bude sveobuhvatno i inkluzivno, odnosno, da ima za cilj razvoj celokupne ličnosti, imajući u vidu njen društveni, ekonomski i kulturni kontekst, kao i da obuhvata programe razvoja životnih veština. U jednom od poglavlja, autorka nastoji da otkrije da li obrazovni proces koji se odvija u kontekstu dominantnog pristupa usmerenog ka kontroli kriminala, ima sposobnost da proizvede neophodnu transformaciju ličnosti. Poseba vrednost monografije leži u kritičkoj analizi savremenih tendencija nastalih u eri neoloberalne ideologije, gde kroz sveobuhvatanu evaluaciju autorka prikazuje ključne promene koje su nastale u sferi kaznene politike, zatvorskih sistema, pristupa osuđeniku, obrazovanju u zatvoru i na kraju, i u svrsi kažnjavanja. Ključne reči: zatvorski sistem, rehabilitacija i korekcija, osuđenici, obrazovni tretman

TDAH Infantil A Través del Modelo Atencional de Posner y Petersen
Authors: Parra Bolaños Nicolás , Peña Carlos Eliu , Caballero Hérnandez Edgar Fernando
Published: March 2022

Diferentes modelos atencionales, han desarrollado paradigmas evalua�vos de los pacientes, a través de bases teóricas sólidas y fundamentadas, con el fin de explicar las alteraciones presentadas en estos. De acuerdo con lo descrito en el modelo de Posner y Petersen, hay tres redes neurales específicas que interac[1]túan entre sí y que cumplen diferentes funciones dentro del proceso cogni�vo para que finalmente la aten[1]ción se dé: la alerta, la orientación y el control ejecu�vo. La correcta interacción y funcionamiento entre estas tres redes es fundamental para el adecuado proceso atencional y se ha propuesto que el desequilibrio en alguna de estas redes conlleva a la aparición de una gran variedad de síntomas, que han despertado el interés entre los inves�gadores, sumando nuevas comprensiones donde se han podido evaluar según diferentes tareas y paradigmas. Hasta ahora, se ha documentado que los pacientes con TDAH pueden presentar princi[1]palmente alteraciones en el control ejecu�vo. Sin embargo, evidencia empírica reciente también apunta a que la red de alerta podría jugar un papel importante en el desarrollo de los síntomas de este trastorno. En una revisión narra�va publicada en el 2020 se evaluó la nueva evidencia disponible para dos modelos teóri[1]cos de la e�ología del TDAH a la luz del modelo de redes atencionales de Posner y Petersen. Estos dos mode[1]los fueron el de inhibición y el cogni�vo-energé�co. El primer modelo propone que hay una pobre inhibición de respuestas en estos pacientes, un proceso compuesto a su vez por tres subprocesos necesarios para el éxito en esta tarea.

Published: March 2022

La permanencia laboral es uno de los factores relevantes al momento de evaluar los costos del recurso humano de una compañía. El presente estudio analiza cuáles son los factores que influyen en la motivación de una persona que se desempeña como trabajador de la industria maderera para que permanezca en su trabajo durante el tiempo suficiente para que se vea balanceada la relación costo-beneficio para la empresa. Esto se constituye en un factor importante para cualquier oficina de recursos humanos ya que es evidente que se debe encontrar un balance entre la permanencia de personal y los costos  invertidos en su capacitación, así como también, afianzar los lazos de empatia y estabilidad para la mejora del clima laboral y tener un repositorio de experiencias a través del personal más antiguo que aporte al know-how de la empresa.

 

En el presente estudio, busca demostrar desde el punto de vista estadístico, como las relaciones laborales a largo plazo se pueden analizar y encontrar un modelo que refleje matemáticamente la importancia de los factores fundamentales en el desempeño laboral con la permanencia en la empresa por una persona más allá del cargo o la posición laboral al interior de la organización.

Published: March 2022

La Psicoterapia Analítico Funcional (PAF) es un modelo terapéutico enmarcado en las terapias contextuales. Utiliza como mecanismo de cambio la relación terapéutica y tiene por objetivo modificar conductas asociadas a la problemática del cliente dentro de la sesión. No se han reportado estudios de la efectividad de PAF en población mexicana; por ello, el presente estudio tuvo por objetivo medir la eficacia de FAP en la disminución de problemas clínicos enmarcados en el Trastorno de Evitación Exponencial. Se realizó un estudio pre-experimental (n=11) con medidas pre-tratamiento y pos-tratamiento. De acuerdo a los resultados obtenidos, se observó una disminución estadísticamente significativa en los puntajes del AAQ-II interpretándose como una disminución del Trastorno de Evitación Experiencial. Bajo estos resultados el presente estudio muestra que FAP es una aproximación efectiva, sin embargo se sugiere hacer diseños con mayor rigor metodológico.

Published: March 2022

O objetivo com este trabalho foi predizer o potencial de populações segregantes do ciclo C 2 do programa de seleção recorrente da Universidade Federal de Viçosa (UFV) visando o melhoramento do porte de feijão carioca, bem como identificar progênies endogâmicas mais promissoras tanto para recombinação como para extração de linhagens. O material genético utilizado neste trabalho constituiu-se de 20 populações F 2 do ciclo C 2 e progênies F 2:3 e F 2:4 derivadas destas populações. Na geração F 2 , as 20 populações foram avaliadas juntamente com cinco testemunhas na safra das águas de 2018, em delineamento de blocos casualizados, com três repetições e parcelas de quatro linhas de quatro metros. Foram avaliados a produtividade de grãos e o diâmetro do hipocótilo (DH) em nível de planta, utilizando uma das linhas centrais da parcela. O potencial de produção das populações foi avaliado com base na metodologia de Jinks e Pooni (1976). As 40 plantas de maior DH, dentro de cada população foram selecionadas e delas derivadas progênies. As 800 progênies F 2:3 e cinco testemunhas foram avaliadas na safra da seca de 2019, utilizando o delineamento de blocos aumentados. Com base nos dados de arquitetura de plantas (ARQ), produtividade (PROD) e aspecto comercial de grãos (AG), foram selecionadas 11 progênies de maior potencial com base no índice da distância genótipo-ideótipo (DGI). Em seguida, na safra das águas de 2019, as 220 progênies F 2:4 selecionadas foram avaliadas no delineamento em látice triplo, quanto aos mesmos caracteres avaliados em F 2:3 . Foram selecionadas 40 progênies para recombinação, sendo as duas melhores progênies de cada população, com base no índice DGI. Também foram selecionadas as 44 progênies melhores classificadas, independente da população de origem, para extração de linhagens. Seis populações se destacaram, com maior probabilidade de gerar linhagens superiores, segundo a metodologia de Jinks e Pooni. O índice de seleção DGI mostrou-se promissor no processo seletivo. As progênies 169, 130, 93 e 91 se destacaram para a extração de linhagens superiores. Já para a recombinação, os ganhos preditos com as progênies selecionadas foram equilibrados e de grande magnitude para os três caracteres, portanto promissoras para dar continuidade ao programa de seleção recorrente. Palavras-chave: Melhoramento do feijoeiro. Seleção recorrente. Índice genótipo-ideótipo.
Uso da covariável número de vizinhos na análise genética de teste clonal e de progênies de Eucalyptus dunnii
Authors:   , Santos Suellen Sales de Oliveira
Published: March 2022

As análises biométricas empregadas nos programas de melhoramento genético de espécies de Eucalyptus têm possibilitado a tomada de decisões de forma acurada pelos pesquisadores. O objetivo deste trabalho foi testar o uso da covaríavel número de vizinhos na correção dos efeitos de competição entre plantas em análises de testes clonais e de testes de progênies de Eucalyptus dunnii. A covariável foi testada em um teste de progênies de 97 famílias com idade de 3 anos, instalado em dois locais, seguindo espaçamentos de 3,85 × 1,95 m e 3,00 × 2,50 m e um teste clonal em três locais com 75 clones e idade de 3,5 anos, ambos conduzidos na empresa CMPC Celulose Riograndense em delineamento de blocos casualizados, 20 repetições e uma planta por parcela. No teste de progênies a covariável provocou mudanças na significância dos efeitos de genótipo e interação G×A, impactando na existência de variabilidade além de demonstrar que grande parte da variação de DAP é devida a competição intergenotípica, sendo mais influenciada pelos vizinhos mais próximos a planta focal. Além disso, mudanças no ordenamento dos indivíduos também foram observadas e aumento da acurácia seletiva em 4%. Nos testes clonais, o uso da covariável impactou na mudança do ranking, evidenciando que muitos materiais que foram selecionados na verdade não são superiores, mas foram beneficiados por não considerar a competição. Baixas correlações de spearman de 0,21 e 0,33 foram encontradas comparando os rankings de 8 e 2 vizinhos com o ranking sem a covariável para a característica IMA. O ordenamento dos clones selecionados para esta característica utilizando 2 vizinhos diferiu cerca de 35% dos clones selecionados sem o uso da covariável. Para densidade básica foram encontrados valores baixíssimos de correlação de spearman de 0,08 e 0,03. Assim, as covariáveis funcionam como uma forma de penalizar os indivíduos que se tornaram superiores pelo fato de terem menos vizinhos vivos e não devido a seu potencial genético. As covariáveis tiveram impacto nas estimativas dos parametros genéticos e componentes de variância, diminuindo a variância residual e da interação G×A e aumentando a herdabilidade e a acurácia de seleção. Portanto o uso das covariáveis é de suma importância na seleção em testes clonais e de progênies pois tornam as análises mais acuradas. Palavras-chave: Melhoramento Florestal. Modelos Mistos.

Coffea canephora and Coffea eugenioides indirect somatic embryogenesis (ISE) has been established and compared during callus formation and somatic embryo regeneration, showing that these species exhibit the same response in vitro. However, intraspecific differences regarding ISE responses have also been reported. ISE is influenced by genetic and physiological aspects. We aimed to: (a) induce ISE in C. canephora and C. eugenioides; (b) identify and quantify the endogenous levels of indole-3-acetic acid (IAA), zeatin (Z) and gibberellic acid GA 3 and GA 4 during the callus induction; and (c) determine the number of gene copies of AUX/IAA33 and YUC4 that are involved in the auxin biosynthetic pathway, and of WOX4 and LEC1 that are involved in the morphogenic pathway. Using liquid chromatography coupled to mass spectrometry (LC-MS), the identification and quantification of IAA, GA 3 , GA 4 and Z was performed in both Coffea. From the fluorescence in situ hybridization, the copy number of the AUX/IAA33, YUC4, WOX4 and LEC1 genes was verified. ISE was established for C. canephora and C. eugenioides, which exhibited the same in vitro response. However, the two Coffea differed in relation to endogenous hormone levels, with the exception of IAA at 90 days. These species possess two gene copies of AUX/IAA33, YUC4, WOX4 and LEC1, corroborating to their diploidy. Therefore, our results show that C. canephora and C. eugenioides differ in the physiological aspect, but not in the genetic aspect investigated here. Thus, our data contribute as a basis to understand the in vitro response and for the improvement of the in vitro propagation procedures. Keywords: Coffee. Plant Tissue Culture. In vitro regeneration.

Factors Affecting Awareness and Attitudes on the Green Purchase Intention of Eco-friendly Products in University Students
Authors: George H. I. C. , Silva H. P. T. N.
Published: March 2022

Pollution and earth-destructive behavior has obliged humans to look for ways to restore natural resources. As such, through the past few decades, the use of eco products has become a well-accepted approach and is now popularizing in the local context. This study derived from a quantitative approach securing data from university students of the Western Province in Sri Lanka. Data were collected from 380 students using stratified random sampling methodology and a self-administered questionnaire, across four universities in order to understand the factors that affect awareness and attitudes on the purchase intention of eco-friendly products. Statistical analysis was applied to describe sample and understand sample composition. Multivariate analysis was conducted employing a factor analysis coupled with a multiple linear regression analysis to identify the latent and underlying factors affecting and the relationship towards the purchase intention. The findings provided a comprehensive generalized profile stating any significant statistical differences on demographics and socio-economic variables. Multivariate analysis suggested that the underlying factors that affect purchase intention are overall awareness, environmental concern and product perception. Further, of the three, environmental concern proved to be the factor that impacts young consumers the most indicating that attention should be focused on this factor when dealing with purchase intention of eco products. The study concluded by suggesting that the use of eco labels on eco products with a price range suitable to attract young consumers would influence the intention for purchasing these products thereby participating in the improvement of the environment.

Authors: Gomes Heron Miguez Gonzalez , Pavanelo Elisangela
Published: March 2022

Esta pesquisa tem como objetivo apresentar a história do conceito de logaritmos. Trata-se de uma pesquisa qualitativa, cuja concepção envolve critérios claros e rigorosos simultâneos a um distanciamento de preconceitos e categorizações prévias tanto o quanto possível. A abordagem que tomamos é bibliográfica, de natureza exploratória, ou seja, é uma pesquisa inicial, em que buscamos explorar vários aspectos de nosso objetivo. Desenvolvemos essa revisão bibliográfica uma em torno da história dos logaritmos, em que percorremos desde sua invenção por Napier no século XVII até as proposições de Euler no século XVIII. Concluímos que não há uma história única, há diversas perspectivas historiográficas possíveis que podem nortear ideologicamente a história contada.

Published: March 2022

Body growth in mammals is an aspect of their biology that has always been interesting and carries important information about the individual’s development. The relationship between growth patterns and factors that are affecting them, such as parasitism, is not entirely clear. In this short communication, we provide information obtained from a young brown bear (Ursus arctos), shot a year after being collared. Analysed growth patterns show a noticeable increase in the weight and circumference of the chest and head. The established low to moderate infestation with Baylisascaris transfuga in relation to absence of other parasites, has not affected the growth processes.
