Authors: Tsao Shu-Han , Lin Kuo-Jen , Chu Sheng-Hsien , Hsieh Ming-Li , Wang Hsu-Han 
Published: August 2021

Background:
We aim to find out the risk factors of delayed postoperative hematuria and the role of preliminary antibiotic treatment in patients receiving transurethral resection of prostate or laser prostatectomy.

Materials and Methods:
The study consisted of 713 patients undergoing surgical intervention for benign prostatic hyperplasia at a single medical center from January 2016 to December 2016. Severe delayed postoperative hematuria was defined as hematuria requiring an emergency department visit or a surgical intervention within 30 days after operation. Variables of interest included age, body mass index, preoperative status of urinary catheter, prostate volume, preoperative diagnosis of pyuria, preliminary antibiotic treatment, duration of operation, type of operation, and use of antiplatelet agents or 5 alpha reductase inhibitors.

Results:
Six hundred and twenty-three of the 713 patients had available data of preoperative transrectal ultrasonography a year before their operation. Delayed postoperative hematuria occurred in 41 patients within 30 days after operation. No statistical significance was found between the different types of operation. Multivariate analysis revealed that the odds of delayed postoperative hematuria increased with preoperative serum prothrombin time (PT) (odds ratio [OR] 1.49, 1.03–1.87), serum white blood cell (WBC) count (OR 1.26 1.05–1.50), serum creatinine (OR 1.59, 1.01–2.50); decreased with preliminary antibiotic treatment (OR 0.26 0.09–0.77).

Conclusion:
Higher preoperative serum PT, WBC count, and creatinine were associated with higher risk of delayed postoperative hematuria, while preliminary antibiotic treatment was associated with lower risk of delayed postoperative hematuria.

Authors: Coblentz Jacqueline , Dias Ana Beatriz , Mansure Jose João , Burnier Miguel Noel 
Published: August 2021

Purpose:
The purpose of this study was to determine the expression of anaplastic lymphoma kinase (ALK) in uveal melanoma (UM) to evaluate its potential utility as a therapeutic target.

Materials and Methods:
A total of 80 formalin-fixed paraffin-embedded enucleated eyes of UM patients, as well as 11 eyes and 11 pulmonary metastases from a rabbit model of human UM, were collected. All samples were stained for ALK using a fully automated immunohistochemical procedure. Human UM cases were classified according to cell type in spindle or epithelioid. Differences in ALK positivity according to cell type were determined using Pearson's Chi-square test.

Results:
In human UM specimens, ALK was positive in 2 of 39 spindle cell type cases (2.5%) and in 13 of 41 (16.25%) epithelioid cell type cases. The difference in ALK expression between cell types was statistically significant (P = 0.002). In the animal model of human UM cells, all cases (100%) were positive for ALK in both ocular and pulmonary lesions.

Conclusion:
ALK is expressed in a small proportion of UM, with statistically significant more expression in the more aggressive epithelioid cell type. Furthermore, when ocular tumors and corresponding lung metastasis from a highly metastatic animal model of UM were examined, ALK was positive in all samples. Collectively, our data suggest that ALK expression may be associated with more aggressive tumors. To the best of our knowledge, this is the first demonstration of the potential of ALK as a therapeutic target in human UM, particularly in aggressive tumors.

Diagnóstico semiótico de un crucero peligroso en la Ciudad de México
Authors: Baltierra Santiago Osnaya 
Published: August 2021

El presente trabajo emerge en el marco del Decenio para la Seguridad Vial (DSV) 2011-2020 propuesto por la Organización de las Naciones Unidas (WHO, 2011). México fue uno de los países que se adhirió al programa, debido al alto número de siniestros de tránsito registrados anualmente. En el DSV se propone un plan de acciones para reducir el índice de accidentes viales en el mundo, las cuales están integradas en cuatro grupos (pilares) a saber, pilar uno “Gestión de la seguridad vial”, pilar dos “Vías de tránsito y movilidad más segura, pilar tres “Vehículos más seguros”, pilar cuatro “Usuarios de vías de tránsito más seguras” y pilar cinco “Respuestas tras los accidentes”. La investigación que aquí se ofrece, obedece al pilar dos, y de manera específica, al apartado de proyectos de investigación que permitan evaluar posibles mejoras en materia de seguridad dirigida a los usuarios más vulnerables en las vialidades. En este contexto, la indagación busca identificar desde un enfoque semiótico las causas que pueden ocasionar un accidente de tránsito en un crucero vial, en el que se observe una relación directa entre los dispositivos para el control de tránsito (señales) y los peatones. Con el fin de interpretar, comprender y explicar dicho fenómeno, para con ello proponer soluciones que mitiguen la problemática.

This work arises from the Decade for Road Safety (DSV) 2011-2020 proposed by the United Nations (WHO: 2011). Mexico was one of the countries where this program was introduced, because of the high number of traffic accidents recorded annually. The DOV proposes a plan of actions to reduce the global road accident rate, which are integrated into four groups (pillars), pillar one "Road safety management", pillar two "Safer roads and mobility", pillar three "Safer vehicles", pillar four "Safer road users" and pillar five "Post-crash responses". Thus, the research offered here, refers to pillar two, and more specifically, to the section on research projects in order to evaluate possible improvements in the area of safety for the most vulnerable road users. In this context, the research seeks to identify from a semiotic approach the causes that can lead to a traffic accident at a crossroads, in which a direct relationship between traffic control devices (signs) and pedestrians can be observed. In order to interpret, understand and explain this phenomenon and propose solutions to mitigate the problem.
Tiempo e historia en la sociología de Gabriel Tarde
Authors: Sazbón Daniel 
Published: August 2021

Desde hace varias décadas se asiste a una recuperación de la figura de Gabriel Tarde (1843-1904) que supone una valorización creciente de la importancia de quien fuera uno de los nombres más celebrados de la sociología francesa, así como importante penalista y criminólogo. En este trabajo nos detendremos en el modo en que en su sociología opera una forma particular de entender la temporalidad de la vida humana.
En lo que sigue intentaremos, por un lado, mostrar la presencia de dicha problemática en su producción, esbozando los aspectos más salientes de dicho tratamiento, y por otro lado contraponer tales rasgos a algunos presentes en la sociología durkheimiana, ubicando a ambas en el contexto más amplio de las transformaciones que atravesaba el tratamiento de la dimensión temporal tanto en la sociología como en la historia.
DIAGNÓSTICO DIFERENCIAL ENTRE TRANSTORNO DO ESPECTRO AUTISTA (TEA) E DISTÚRBIO ESPECÍFICO DE LINGUAGEM (DEL)
Authors: Souza Liz Passos Nascimento 
Published: August 2021

O Transtorno do Espectro Autista é caracterizado principalmente por prejuízos na comunicação e interação social e padrões restritos e repetitivos de comportamento, atividades e interesses. O Distúrbio Específico de Linguagem apresenta prejuízos na linguagem, o portador deste distúrbio apresenta dificuldade para compreender ou produzir palavras e/ou frases em uma conversa. Em alguns casos, tentam compensar o prejuízo para usar palavras com gestos e outras expressões corporais. Ambos são transtornos do neurodesenvolvimento, apresentam características linguísticas semelhantes em seus sintomas e diferenciá-los torna-se fundamental para a condução do tratamento adequado para cada um deles, uma vez que sua não identificação pode atrasar o tratamento, acarretando prejuízo pessoal, social e profissional aos portadores. Este trabalho tem como objetivo investigar as diferenças e traçar uma linha de raciocínio para o diagnóstico diferencial de TEA e DEL. Foi realizada uma pesquisa exploratória através de revisão bibliográfica e nota-se que a grande diferença entre eles é a debilidade funcional, onde os portadores de TEA apresentam maior comprometimento, bem como prejuízos nas áreas de cognição e interação social, diferenciando-se dos portadores de DEL.

Published: August 2021

Abstract. We analysed the biogenic volatile organic compound (BVOC)
emissions from rapeseed leaf litter and their potential to create secondary
organic aerosols (SOAs) under three different conditions, i.e., (i) in the
presence of UV light irradiation, (ii) in the presence of ozone, and (iii) with
both ozone and UV light. These experiments were performed in a controlled
atmospheric simulation chamber containing leaf litter samples, where BVOC
and aerosol number concentrations were measured for 6 d. Our results
show that BVOC emission profiles were affected by UV light irradiation which
increased the summed BVOC emissions compared to the experiment with solely
O3. Furthermore, the diversity of emitted VOCs from the rapeseed litter
also increased in the presence of UV light irradiation. SOA formation was
observed when leaf litter was exposed to both UV light and O3,
indicating a potential contribution to particle formation or growth at local
scales. To our knowledge, this study investigates, for the first time, the
effect of UV irradiation and O3 exposure on both VOC emissions and SOA
formation for leaf litter samples. A detailed discussion about the processes
behind the biological production of the most important VOC is proposed.
Estimation of ship emission rates at a major shipping lane by long-path DOAS measurements

Published: August 2021

Abstract. Ships are an important source of SO2 and NOx, which are key parameters of air quality. Monitoring of ship emissions is usually carried out using in situ instruments on land, which depend on favourable wind conditions to transport the emitted substances to the measurement site. Remote sensing techniques such as long-path differential optical absorption spectroscopy (LP-DOAS) measurements can supplement those measurements, especially in unfavourable meteorological conditions. In this study 1 year of LP-DOAS measurements made across the river Elbe close to Hamburg (Germany) have been evaluated. Peaks (i.e. elevated concentrations) in the NO2 and SO2 time series were assigned to passing ships, and a method to derive emission rates of SO2, NO2 and NOx from those measurements using a Gaussian plume model is presented. A total of 7402 individual ship passages have been monitored, and their respective NOx, SO2 and NO2 emission rates have been derived. The emission rates, coupled with the knowledge of the ship type, ship size and ship speed, have been analysed.
Emission rates are compared to emission factors from previous studies and show good agreement. In contrast to emission factors (in grams per kilogram fuel), the derived emission rates (in grams per second) do not need further knowledge about the fuel consumption of the ship.
To our knowledge this is the first time emission rates of air pollutants from individual ships have been derived from LP-DOAS measurements.
Satellite soil moisture data assimilation for improved operational continental water balance prediction
Authors: Tian Siyuan , Renzullo Luigi J. , Pipunic Robert C. , Lerat Julien , Sharples Wendy , Donnelly Chantal 
Published: August 2021

Abstract. A simple and effective two-step data assimilation framework was developed to improve soil moisture representation in an operational large-scale water balance model. The first step is a Kalman-filter-type sequential state updating process that exploits temporal covariance statistics between modelled and satellite-derived soil moisture to produce analysed estimates. The second step is to use analysed surface moisture estimates to impart mass conservation constraints (mass redistribution) on related states and fluxes of the model using tangent linear modelling theory in a post-analysis adjustment after the state updating at each time step. In this study, we assimilate satellite soil moisture retrievals from both Soil Moisture Active Passive (SMAP) and Soil Moisture and Ocean Salinity (SMOS) missions simultaneously into the Australian Water Resources
Assessment Landscape model (AWRA-L) using the proposed framework and evaluate its impact on the model's accuracy against in situ observations across water balance components. We show that the correlation between simulated surface soil moisture and in situ observation increases from 0.54 (open loop) to 0.77 (data assimilation). Furthermore, indirect verification of root-zone soil moisture using remotely sensed Enhanced Vegetation Index (EVI) time series across cropland areas results in significant improvements from 0.52 to 0.64 in correlation. The improvements gained from data assimilation can persist for more than 1 week in surface soil moisture estimates and 1 month in root-zone soil moisture estimates, thus demonstrating the efficacy of this data assimilation framework.
Pathologies bucco-dentaires chez les enfants pris en charge sous anesthésie générale à l’hôpital général Idrissa Pouye de Dakar
Authors: Djiré Hamed 
Published: August 2021

Introduction : La santé buccodentaire fait partie intégrante de la santé globale des enfants. Son altération peut avoir des répercussions fonctionnelles, psychologiques et sociales sur le bien-être de l’enfant. Les pathologies bucco-dentaires peuvent être source de cette altération. L’objectif de ce travail était d’évaluer les aspects épidémiologiques, cliniques et thérapeutiques des pathologies bucco-dentaires chez les enfants pris en charge sous anesthésie générale au service d’odontostomatologie de l’hôpital général Idrissa Pouye (HOGIP) de Dakar. Matériel et méthodes : Il s’agissait d’une étude transversale descriptive qui s’est déroulée sur une période de 3 mois du 15 juillet 15 octobre 2019 et a concernée 25 dossiers de patients d’âge pédiatrique. Elle a eu pour cadre le service d’odontostomatologie de l’hôpital général Idrissa Pouye de Dakar. Nous avons exploité les dossiers des patients pris en charge sous anesthésie générale. Résultats : Dans notre étude, nous avons une prédominance masculine avec 56%. La tranche d’âge des 6 à 10 ans représentait 48% de l’échantillon avec une moyenne de 7,8 ans ± 3,5. La symptomatologie clinique était dominée par la tuméfaction (80% des cas). Les pathologies tumorales étaient le plus souvent rencontrées (14 cas, 56%). Parmi ces tumeurs, la grenouillette était retrouvée dans 9 cas (64,29%). La marsupialisation et le cerclage péri-mandibulaire ont été les interventions les plus pratiquées (respectivement 36% et 32% des cas). Conclusion : La prise en charge de ces pathologies peut se faire soit sous anesthésie locale ou soit sous anesthésie général. Certaines situations, cliniques ou générales de l’enfant, nécessitent le recourt à l’anesthésie générales pour une meilleure prise en charge.

Connaissances et attitudes des parents face a la contraception des adolescentes a Yirimadio, Bamako
Authors: Diallo B 
Published: August 2021

Introduction : L’adolescence est une période de transition entre l’enfance et l’âge adulte, au cours de laquelle l’individu acquiert la plénitude de ses fonctions de reproduction où survient une sexualité précoce avec des conséquences comme les grossesses non désirées. L’objectif était d’étudier les déterminants qui influent sur les connaissances et attitudes des parents face à l’utilisation des services de planification familiale (PF) par les adolescentes dans l’aire de santé de Yirimadio. Matériel et méthodes : Nous avons mené une étude transversale descriptive. Elle s’est déroulée pendant 2mois du 07 décembre 2019 au 07 février 2020. Les parents âgés de plus de 30 ayant acceptés de répondre aux questions étaient inclus dans cette étude. La taille de l’échantillon était de 305. Les données ont été collectées avec l’application Kobo Collecte et analysées sur SPSS version 21. Nous avons obtenu le consentement des répondants. Résultats : Au total 76,06% des parents associaient la PF à l’espacement des naissances et 7,54% pensaient que son utilisation avait des inconvénients sur la santé. Environ 92% ont affirmé son avantage. Environ 36,4% des parents ont affirmé l’avantage de la PF pour les adolescentes. Pour 66,2% des parents l’utilisation des services de PF par les adolescentes est mauvaise, 64% que la PF n’a pas d’avantage sur leur santé et 78,09% ont affirmé avoir une communication moyenne avec eux. Conclusion : La majorité des parents refusent que leurs adolescentes fréquentent des services de PF. Face à cette situation, il serait important de mettre un accent sur la mobilisation et IEC au sein de la communauté.

Connaissances Attitudes et Pratiques des agents de santé de la ville de Ségou sur les cancers de l’enfant
Authors: Bah A 
Published: August 2021

Introduction : Les cancers de l’enfant sont rares et représentent environ 1% de la globalité des cancers. Cependant, leur sévérité, la durée de leur traitement et leur évolution au long cours en font un problème de santé publique majeur. Le but de notre étude était d’évaluer les connaissances, attitudes et pratiques des agents de santé de la ville de Ségou sur les cancers de l’enfant. Méthodologie : Il s’agissait d’une étude transversale, descriptive et analytique menée auprès des agents de santé de la ville de Ségou. Résultats : Trois cent dix agents de santé de la ville de Ségou ont répondu à notre questionnaire dont 32 médecins généralistes, 31 médecins spécialistes, 32 assistants médicaux, 41 infirmiers du second cycle, 88 infirmiers de premier cycle, 44 aides-soignants et Matrones, 13 techniciens de laboratoire 29 sages-femmes Les agents de santé qui ont déclaré que les cancers de l’enfant sont des affections malignes représentaient 55,16%. Dans notre étude, 73,5% des agents de santé déclaraient n’avoir pas suspecté ou diagnostiqué un cancer de l’enfant durant leur carrière, 75% n’ont jamais participé à la prise en charge d’un enfant atteint d’un cancer au cours de leur carrière. Conclusion : Le domaine de l’oncologie pédiatrique est méconnu des agents de santé de la ville de Ségou, en tant que 1ers contacts lors de l’apparition de symptômes pouvant faire évoquer un cancer. La discipline est peu enseignée dans le cursus de formation des agents de santé au Mali.

Sarcoidosis of the pineal region, dorsal mesencephalon, and periaqueductal region: Case report and systematic review
Authors: Khelifa Adel , Bennabi Walid , Aichaoui Fayçal , Meziani Salim , Morsli Abdelhalim 
Published: August 2021

Background: The central nervous system is an unusual location of sarcoidosis, which commonly affects the cranial nerves, meninges, hypothalamus, and pituitary gland. Involvement of the pineal region is extremely rare. This systematic review focused on the diagnosis and management of pineal region sarcoidosis, dorsal mesencephalon, and periaqueductal region.
Objectives: This study aimed to discuss diagnostic modalities and best management tools of the aforementioned pathology.
Methods: ScienceDirect, PubMed, and Google Scholar databases were searched for English or French articles about sarcoidosis of the pineal region, dorsal mesencephalon, and periaqueductal region. The clinical case of a patient managed at our department that we believe is directly relevant to this review is also presented. Patients’ demographics, clinical presentations, presence of hydrocephalus, other sarcoidosis locations in the central nervous system, and medical treatment were collected. Surgical management, surgical approach, and outcomes and complications of each procedure were also obtained. This study was conducted in agreement with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement.
Results: Fifteen cases were examined. The study sample consisted of nine (60%) male and six (40%) female, and the mean age was 32 years. Eight (53%) patients had hydrocephalus, and the predominant clinical presentations were signs of increasing intracranial pressure (headaches, vomiting, and papilledema). Six (40%) patients had diplopia, and convergence–retraction nystagmus was noted in three (20%) patients. Argyll Robertson sign was present in one patient and suspected in another patient (13%). Medical treatment consisted mainly of steroids (93% of cases). Open surgery on the pineal region was performed in five patients, and four of them reported to have serious complications (such as ophthalmoplegia, hemianopsia, hemiparesis, bilateral third cranial nerve paresis, and cerebellar syndrome). Endoscopic management was performed in two patients without complications.
Conclusion: To treat hydrocephalus, brain imaging is mandatory in patients with sarcoidosis if intracranial hypertension is suspected. In pineal region sarcoidosis, management of hydrocephalus is the priority, followed by medical treatment of the lesion. Open surgery of any approach presents a high risk of complications; thus, an endoscopic approach is the preferred management, as it treats hydrocephalus and makes biopsy possible with minimal risk.
