Objectif : Déterminer les facteurs de risque des infections nosocomiales (IN) chez les patients âgés hospitalisés dans le Service de Médecine Interne et Maladies Infectieuses du Centre Hospitalier    de Kiffa. Patients et Méthodes : Il s'agissait d'une étude transversale et descriptive, menée du 1er janvier au 31 mai 2017. Tous les patients hospitalisés depuis au moins 48 h étaient inclus dans l'étude. Résultat : Au total 73 sujets âgés ont été hospitalisés soit une proportion de 24,17 %.  Le sex-ratio M/F était de 2,31 et l'âge moyen était de 75±10 ans avec des extrêmes de (60-90 ans). La majorité de nos patients (58,9%) avait une hospitalisation supérieure à sept jours. La fièvre associée à l´altération de l´état général étaient le principal motif de consultation.  Les infections de l'appareil respiratoire représentaient 49,7% suivi des appareils urogénital (28,8%), digestif (16,4%) et cutanéomuqueux (6,8%). Les facteurs de susceptibilité aux infections IN étaient liées à l'âge (p=0,00062), à la perte d´autonomie (p=0,0004), altération de l´état général (p=0,0004), aux portes d´entrées (p=0,0001), aux poly pathologies (p=0,02) et à la poly médication (p=0,04). La létalité globale était 15,1% malgré a la prise en charge. Conclusion : Ce travail permet de penser que les sujets âgés dans un tel contexte sont largement exposés au risque élevé d´IN, même si, pour des raisons techniques, les examens microbiologiques n'ont pas été effectués dans notre population d'étude.

Published: July 2021

But : Déterminer les aspects épidémiologiques, étiologiques, thérapeutiques et évolutifs de la gangrène de Fournier. Patients et Méthodes : Il s'agissait d'une étude rétrospective et descriptive portant sur 10 patients ayant été traités dans quatre principaux hôpitaux publics de Bujumbura pour Gangrène de Fournier. Elle s'étend sur une période de deux ans. Résultats : La fréquence de la GF était de 0,102%. L'âge moyen était de 46,7 ans. Tous nos patients étaient masculins. Six malades sur 10 avaient consulté entre 5 et 15 jours après le début des signes. Les antécédents urogénitaux prédominent (40%). Les facteurs favorisants étaient le diabète (40%), la paraplégie (20%) et le VIH (10%). La GF secondaire représentait 7 cas dont 4 urogénitales, 2 cutanées et 1 proctologique. Les lésions se limitaient au périnée chez 80% des malades. L'examen bactériologique retrouvait l'Escherichia Coli (70%). Tous les décès (2 cas) avaient un ISGF de 10,5. L'association céphalosporine, aminoside et imidazole était principalement prescrite (60%). Le traitement chirurgical était essentiellement le débridement (90. La dérivation urinaire était faite chez tous les malades. Un séjour moyen était 93,6 jours. Les complications retrouvées étaient choc septique (20%), insuffisance rénale (40%) et anémie (20%). Conclusion : La GF reste une pathologie relativement rare. La consultation tardive explique le retard diagnostique. Les étiologies sont dominées par les causes urogénitales avec le diabète comme facteur de risque principal. La consultation précoce et le contrôle des facteurs favorisant réduiraient le taux de mortalité.

Qualidade de vida de pacientes operados por câncer gastrointestinal: estudo comparativo das fases 30 e 60 dias pós cirurgia
Authors: Tartuce Luciana Marya Gusmão , Guimarães Valeriana de Castro , Costa Neto Sebastião Benício
Published: July 2021

Como conhecido problema de saúde pública, o câncer se destaca, tanto por sua incidência, quanto pelo impacto do seu diagnóstico e tratamento, podendo gerar desordem emocional e psicossocial nos pacientes oncológicos, reduzindo sua percepção de qualidade de vida (QV). A QV é um importante parâmetro da resposta do paciente à doença e ao tratamento por mapear sintomas, controlar efeitos colaterais e contribuir na elaboração de intervenções e na integralidade nos  cuidados em saúde. O objetivo deste estudo foi avaliar a QV relacionada à saúde de pacientes operados por câncer do aparelho gastrointestinal, assistidos na clínica cirúrgica de um hospital universitário de referência em Goiás, comparando-se as fases 30 e 60 dias pós-cirurgia. Método: Trata-se de um estudo descritivo, exploratório e quantitativo sobre QV, envolvendo 31 participantes, de ambos os sexos, adultos, operados por câncer do aparelho gastrointestinal, no período de março a dezembro de 2015, empregando-se os questionários WHOQOL-bref e EORTC QLQ C-30. A análise estatística consistiu-se em avaliação dos escores funcionais e de sintomas, com nível de significância de 0,05. Resultados: Dos participantes, na maioria mulheres, provenientes da capital, com faixa etária predominante entre 60 e 69 anos, prevalência de casados, aposentados, católicos e nível de escolaridade fundamental. O diagnóstico predominante foi o câncer colorretal, sendo que a maior parte dos pacientes ficou, em média, 14 dias internado e tinha mais de uma experiência de internação. A qualidade de vida foi considerada regular nos dois momentos, sendo que o domínio mais afetado foi o Físico. Conclusão: Constatou-se, após o processo cirúrgico, que a QV percebida dos participantes teve poucas alterações significativas comparando-se os momentos 30  e 60 dias pós-cirúrgicos, sendo que esta modalidade de tratamento, em geral, pôde ser considerada como benéfica. Além disso, compreende-se pela necessidade de realização de novos estudos que possam aumentar a casuística estudada, quanto elucidar a atribuição de sentidos dos participantes aos diversos atos que envolvem o próprio tratamento cirúrgico do câncer.
Currículo educacional: um olhar sobre suas concepções teóricas
Authors: Andrade Wendel Melo , Santos Maria José Costa , Brandão Jorge Carvalho
Published: July 2021

No campo que envolve os estudos sobre currículo, suas muitas concepções teóricas evidenciam um processo de construção e de ressignificação do seu conceito. Dentre estas concepções teóricas, podemos destacar as tradicionais, as críticas e as pós-críticas. Tais abordagens teóricas possibilitam compreender melhor o seu conceito sob diferentes contextos e perspectivas. Diante disso, este trabalho discute sobre o currículo educacional com o objetivo de evidenciar essas teorias. Metodologicamente esta investigação privilegia o método de abordagem exploratória, contando com o procedimento de pesquisa bibliográfica, apoiando-se principalmente nos escritos de Lopes e Macedo (2011), Ranghetti e Gesser (2011) e Silva (2017). Com base nos estudos realizados, percebemos que nas concepções tradicionais de currículo os conhecimentos se concentram nas questões técnicas, principalmente no conteúdo e no modo como ele é linearmente transmitido. Já as concepções críticas de currículo questionam este caráter técnico-sistemático do currículo tradicional, focando na superação dos problemas sociais a partir da conscientização do sujeito e da consequente promoção de ações de transformação e emancipação. Por sua vez as concepções pós-críticas inserem nas discussões sobre o currículo as questões culturais, de raça e etnia, de gênero, entre outras. Consideramos relevante a compreensão das concepções teóricas do currículo como algo que é vivenciado cotidianamente no ambiente escolar e que , portanto, deve ser  melhor entendido.

Published: July 2021

Epidemiological data on death rates and incidence of Breast Cancer (BC) are still alarming, highlighting the need for new strategies of diagnosis and therapy. Our group has previously described a new antibody in Fab format, FabC4, for diagnostics, staging, and prognosis of BC. Objectives: To map the FabC4 epitopes and evaluate those for their diagnostic potential. Methods: A Phage Display-based assay against FabC4 was performed to identify and characterize peptides as new epitopes of BC. The selected peptides were also evaluated for their reactivity to patient sera through ELISA assay. We finally conducted molecular docking to assess the best conformation of FabC4-epitopes. Results: Four peptides-displaying phages differentiated sera samples from 50 patients with BC, benign disease, and from healthy women. The corresponding peptides were chemically synthesized (pA5, pA7, pC4 and pD6) and bound to FabC4. The peptide pD6 differentiated the neoplastic samples from benign and healthy sera. Molecular docking analyzes confirmed the interaction between FabC4 and the selected peptides. Conclusion: We have successfully mapped the FabC4 epitopes with diagnostic potential, opening new avenues for the understanding and treatment of BC.

PENCEGAHAN DAN PEMBATALAN PERKAWINAN
Authors: Mukri Mukmin
Published: July 2021

Mengingat tidak seharusnya suatu perkawinan itu dibatalkan, karena suatu perkawinan merupakan suatu hal yang bersifat religius dan tidak boleh dipermainkan. Dan karena dalam suatu perkawinan tidak hanya mengikat hubungan satu laki-laki dengan satu perempuan, melainkan mengikat semua keluarga besar yang ada dalam nasab keluarga dan perkawinan yang terjadi tidak hanya hubungan antara manusia dengan manusia (hablu minan nas), melainkan melibatkan hubungan antara manusia dengan Allah SWT.,(hablu minallah), sehingga perkawinan tidak mudah dibatalkan. Pembatalan perkawinan merupakan suatu tindakan guna memperoleh keputusan pengadilan yang menyatakan bahwa perkawinan yang dilaksanakan batal. Pengetahuan pihak KUA terhadap keabsahan calon mempelai tidak lain karena akan berimbas pada sah dan tidaknya perkawinan tersebut. Sehingga dipandang penting adanya pencegahan yang dilakukan, guna tidak terjadinya pembatalan perkawinan. Maka diperlukanlah langkah-langkah yang harus ditempuh seperti lembaga pemerintah Kantor Urusan Agama (KUA) supaya dapat mengambil tindakan untuk mengantisipasi terjadinya pembatalan perkawinan.

Published: July 2021

Radiation technology has been providing a useful tool to modify polymers involving the radiation crosslinking of hydrogels. In the present work, two kinds of hydrogels composed gelatin and carboxymethyl chitosan (gelatin/CM-chitosan), and carboxymethyl chitin (gelatin/CM-chitin) were prepared by the radiation crosslinking. The resulting hydrogels were freeze-dried, sterilized under gamma-ray at a sterilization dose of 25 kGy, and characterized to be utilized as the scaffolds for culturing adipose-derived stem cells (hADSCs). The physicochemical properties, biodegradability, and cytotoxicity of these scaffolds were also investigated. The results indicated that both CM-chitosan and CM-chitin much improved the swelling capacity, porosity, and pore size of the gelatin-derived scaffolds. The swelling degree of gelatin/CM-chitosan and gelatin/CM-chitin scaffolds was about 7-9 g/g after 6 hrs immerging in PBS, and their porosity was about 70-73% with pore size ranging from 100 to 300 mm. The results also revealed that the compressive modulus of gelatin/CM-chitosan and gelatin/CM-chitin was 45.6 and 66.4 kPa, respectively, which were suitable for soft tissue engineering. Both scaffolds were enzymatically biodegradable by collagenase and non-cytotoxic for hADSCs with an RGR of ~97%. Thus, the resultant scaffolds can be suitably utilized for culturing hADSC in practice to regenerate soft tissues.
Temporal and Petrogenetic Links Between Mesoproterozoic Alkaline and Carbonatite Magmas at Mountain Pass, California
Authors: Watts Kathryn E. , Haxel Gordon B. , Miller David M.
Published: July 2021

Mountain Pass is the site of the most economically important rare earth element (REE) deposit in the United States. Mesoproterozoic alkaline intrusions are spatiotemporally associated with a composite carbonatite stock that hosts REE ore. Understanding the genesis of the alkaline and carbonatite magmas is an essential scientific goal for a society in which critical minerals are in high demand and will continue to be so for the foreseeable future. We present an ion microprobe study of zircon crystals in shonkinite and syenite intrusions to establish geochronological and geochemical constraints on the igneous underpinnings of the Mountain Pass REE deposit. Silicate whole-rock compositions occupy a broad spectrum (50–72 wt % SiO2), are ultrapotassic (6–9 wt % K2O; K2O/Na2O = 2–9), and have highly elevated concentrations of REEs (La 500–1,100× chondritic). Zircon concordia 206Pb/238U-207Pb/235U ages determined for shonkinite and syenite units are 1409 ± 8, 1409 ± 12, 1410 ± 8, and 1415 ± 6 Ma (2σ). Most shonkinite dikes are dominated by inherited Paleoproterozoic xenocrysts, but there are sparse primary zircons with 207Pb/206Pb ages of 1390–1380 ± 15 Ma for the youngest grains. Our new zircon U-Pb ages for shonkinite and syenite units overlap published monazite Th-Pb ages for the carbonatite orebody and a smaller carbonatite dike. Inherited zircons in shonkinite and syenite units are ubiquitous and have a multimodal distribution of 207Pb/206Pb ages that cluster in the range of 1785–1600 ± 10–30 Ma. Primary zircons have generally lower Hf (<11,000 ppm) and higher Eu/Eu* (>0.6), Th (>300 ppm), Th/U (>1), and Ti-in-zircon temperatures (>800°C) than inherited zircons. Oxygen isotope data reveals a large range in δ18O values for primary zircons, from mantle (5–5.5‰) to crustal and supracrustal (7–9‰). A couple of low-δ18O outliers (2‰) point to a component of shallow crust altered by meteoric water. The δ18O range of inherited zircons (5–10‰) overlaps that of the primary zircons. Our study supports a model in which alkaline and carbonatite magmatism occurred over tens of millions of years, repeatedly tapping a metasomatized mantle source, which endowed magmas with elevated REEs and other diagnostic components (e.g., F, Ba). Though this metasomatized mantle region existed for the duration of Mountain Pass magmatism, it probably did not predate magmatism by substantial geologic time (>100 m.y.), based on the similarity of 1500 Ma zircons with the dominantly 1800–1600 Ma inherited zircons, as opposed to the 1450–1350 Ma primary zircons. Mountain Pass magmas had diverse crustal inputs from assimilation of Paleoproterozoic and Mesoproterozoic igneous, metaigneous, and metasedimentary rocks. Crustal assimilation is only apparent from high spatial resolution zircon analyses and underscores the need for mineral-scale approaches in understanding the genesis of the Mountain Pass system.

In this investigation, we examined the chemical composition, physicochemical properties, and organic matter of therapeutic mud from Lake Noot in the Arkhangai province of Mongolia. The therapeutic mud from “Lake Noot” is used in the pelotherapy of local health care services for some time but without deep characterization. Due to this, a study of therapeutic mud samples was required. Our research concentrated on identifying general characteristics, organic matter, mineralogical, and chemical composition of therapeutic mud at two different Lake Noot sites. Results showed that the therapeutic mud belongs to the continental hydrogen sulfide sticky mud type. The total organic matter in the therapeutic mud of Lake Noot was 14.44%. Total organic matter contains a humic substance of 42.17%, lipid 16.62%, and carbohydrate 7.13%. A total of 172 compounds were identified in the dissoluble organic matter of therapeutic mud, mainly of natural origin, using the gas chromatography-mass spectrometry (GC/MS) method. The dominant compounds were saturated and unsaturated hydrocarbons with 13–44 carbon atoms and carboxylic acids and their ethers. Some of the identified organic compounds have been reported antimicrobial, anti-inflammatory, antibacterial, and antifungal properties.
Evaluating the Contribution of Emotional Valence to Associative Memory: Retrieval Practice Matters
Authors: Nie Aiqing , Jiang Guimei , Li Mengmeng
Published: July 2021

Research has indicated that emotional valence can influence associative memory, but it is less clear whether it still works when the retrieval practice is controlled. The current study combined an associative recognition task with a paradigm of retrieval practice, with negative, neutral, and positive word pairs serving as stimuli. Results revealed that intact pairs possessed higher correct response proportions than rearranged, old+new, and new pairs; the rearranged pairs were more likely to be classified as intact; a negative impairment effect was observed in both learning conditions; the retrieval practice effect was sensitive to the interaction of emotional valence by pair type. We shows that the involvement of the recollection-driven process varies with pair type, providing telling evidence for the dual-process models; the occurrence of negative impairment effect conforms to the account of spontaneous interactive imagery; the contribution of desirable difficulty framework is modulated by the interaction of emotional valence by pair type.

Spatial ability is known to have an important role in learning different skills in childhood and achieving success in specific professions. A vast majority of the studies on this topic have focused on adults, and few on in children. In this study, eight tasks were selected to assess eight factors of spatial ability and were modified to be suitable for children. Computerized versions of the tasks were designed and their reliability was measured. One-hundred and ten Iranian children aged 9 to 12 years old participated in the study. In order to assess the test-retest reliability, half of the participants were tested twice. Internal consistency reliability was calculated for some of the tasks. Intraclass correlation coefficients were obtained by test-retest reliability analysis for all tasks ranging from 0.689 to 0.997. The range of Cronbach's α coefficient was found to be between 0.335 and 0.784. The range of the ω coefficient was from 0.428 to 0.798. Each modified task had adequate reliability for assessing the respective spatial ability factors. This battery can help to identify the level of spatial performance in children.
The Effect of Reviewer Profile Photo on Purchase Decision: Evidence from Event-Related Potentials
Authors: Tang Xiaoli , Song Zhijie
Published: July 2021

Although the number of studies on online reviews is growing, the impact of reviewer photo on consumer purchase decision-making has not yet been examined systematically. In particular, the underlying neural mechanisms have remained underexplored. Thus, the present study investigated whether and how reviewer photos affects consumers to make a purchase decision by using event-related potentials (ERPs). At the behavioral level, participants demonstrated a higher purchase rate with a shorter RT in situations with reviewer photos compared to situations without reviewer photos. Meanwhile, at the neural level, compared with situations without reviewer photos, situations with reviewer photos attracted more rapid attention resources at the early automatic processing phase, which induced a greater P2 amplitude, then mobilized more sustained attention allocation at the cognitive monitoring phase due to its evolutionary significance which elicited a more negative N2 amplitude, and finally resulted in a better evaluative categorization with higher motivational and emotional arousal due to its social presence which evoked a larger late positive potential (LPP) amplitude at the late elaborate cognitive processing phase. Those results illuminated the neural pathway of purchase decision-making when consumers were exposed in different conditions of reviewer photo. Moreover, the current study provided evidence for the underlying influence of reviewer photo on purchase decision-making in online shopping.
The Relationship Between Internal Motor Imagery and Motor Inhibition in School-Aged Children: A Cross-Sectional Study

Published: July 2021

Functional equivalence hypothesis and motor-cognitive model both posit that motor imagery performance involves inhibition of overt physical movement and thus engages control processes. As motor inhibition in internal motor imagery has been fairly well studied in adults, the present study aimed to investigate the correlation between internal motor imagery and motor inhibition in children. A total of 73 children (7-year-olds: 23, 9-year-olds: 27, and 11-year-olds: 23) participated the study. Motor inhibition was assessed with a stop-signal task, and motor imagery abilities were measured with a hand laterality judgment task and an alphanumeric rotation task, respectively. Overall, for all age groups, response time in both motor imagery tasks increased with rotation angles. Moreover, all children’s response times in both tasks decreased with age, their accuracy increased with age, and their motor inhibition efficiency increased with age. We found a significant difference between 7-year-olds and 9-year-olds in the hand laterality judgment task, suggesting that the involvement of motor inhibition in internal motor imagery might change with age. Our results reveal the underlying processes of internal motor imagery development, and furthermore, provide practical implications for movement rehabilitation of children.
Unique Mechanisms for the Availability of Declarative Memory Elements and the Strengthening of Cognitive Operations
Authors: Hirsch Dale A. , Was Christopher A. , Graham Erin N.
Published: July 2021

The purpose of this study was to investigate the role of memory for prior cognitive operations and availability of declarative memory elements in long-term semantic priming. The impetus for this investigation was the role of working memory (WM) in complex cognitive processing. Empirical estimates of WM are too limited to explain complex cognitive processes. Therefore, contemporary models of WM propose access to long-term memory (LTM) to expand these limits. The priming literature provides one theoretical mechanism for access to LTM: long-term semantic priming. However, explanations for long-term semantic priming include both increased availability of LTM elements and the facilitation of prior cognitive operations. Our goal was to examine if the facilitation of prior cognitive operations is dependent on the availability of previously encountered LTM elements. A task used in previous research proposed to capture the facilitation of cognitive operations coupled with a directed forgetting manipulation was used to examine this relationship. Three experiments were conducted to that end. All experiments resulted in facilitation of the procedure of categorization. Experiments 1 and 2 additionally found relatively poor recognition for items that participants were told to forget despite the fact that categorization was facilitated for related items. Experiment 3 resulted in similarly poor recognition for category names that participants were told to forget. Taken together, the experiments in this investigation demonstrate a clear separation between the cognitive operations and declarative elements of the categorization task. Namely, the continued availability of declarative elements is not necessary for the subsequent facilitation of categorization operations.

Published: July 2021

Background: Colorectal cancer (CRC) is among the most common and preventable cancers, the incidence and risk factors of which are different in various populations. Objectives: The present study aims at assessing incidence rate, risk factors, and symptoms of CRC among the populations aged 50 to 70 years old covered by the health centers in Arak, as well as evaluating participation rate in the CRC screening program. Methods: The present cross-sectional study was conducted from 2016 to 2019 among all of the individuals aged 50 to 70 years old, who were referred to rural, urban, and suburban health centers in Arak for CRC screening, and their data were recorded in the Sib system. The participation rate, risk factors (family and individual history of CRC, colorectal adenoma, and inflammatory bowel disease), symptoms (lower gastrointestinal bleeding, constipation with or without diarrhea, and weight loss), and crude incidence rate of CRC were calculated in the age range. Results: The mean (SD) age of the CRC was 59.72 (5.56) years. In addition, the individuals’ participation rate in the program was about 44.2%, which was more among women (55.5%) and villagers (93.7%). Most subjects complained of constipation in the last month and CRC family history. The CRC crude incidence rates were 35.93 (95% CI: 25.55 - 50.54), 40.96 (95% CI: 29.81 - 56.29), 43.76 (95% CI: 32.22 - 59.43), and 52.84 (95% CI: 40.05 - 69.71) per 100000 individuals during 2016, 2017, 2018, and 2019, respectively. Conclusions: The participation rate in the CRC screening program was low, and the trend of the cancer crude incidence rate increased among the populations aged 50 to 70 years. Finally, informing about the recognition of the risk factors and symptoms of cancer, as well as the timely referral for screening was considered essential.

Background: Hepatitis B Virus (HBV) is a universal health challenge all around the world. Several factors like viral load, genetic characteristics, age, sex, and immune status contribute to variable clinical outcomes of HBV infection. The sequels of HBV infection vary remarkably among persons ranging from the spontaneous deletion of infection to persistent infection. Objective: The present study aimed to evaluate the association of single nucleotide polymorphisms IL10-1082 with HBV clearance. Methods: Sixty subjects with Chronic Hepatitis B (CHB) infection and 60 subjects who spontaneously recovered HBV were enrolled in the study. The IL-10-1082 polymorphisms were determined by Polymerase Chain Reaction with Restriction Fragment Length Polymorphism (PCR–RFLP). Results: The clearance of HBV infection demonstrated a significant association with IL-10-1082 polymorphisms in the GG genotype (P = 0.03), while there was no association with other genotypes. Reduced risk of chronic hepatitis B infection was associated with IL-10-1082 GG (OR: 2.33, 95% CI: 1.07 - 5.09). Besides, IL-10-1082 A/G alleles did not differ clearly between the two study groups (P = 0.07) Conclusions: The IL-10-1082 polymorphisms may be associated with a reduced risk of CHB infection and recovery after HBV infection.
