Time-averaged flow characterisations in a bimodal gravel-bed stream and relative role of sediment depositions on near-bed coherent flow structures
Authors: Das Ratul , Malakar Pritam , Datta Akash 
Published: February 2024

Abstract
The present study aims to quantify experimentally the relative role of sediment depositions on near-bed flows and turbulence in a gravel-bed stream. Time-averaged velocity was measured over a sand-filled gravel-bed stream with four cases of sediment depositions and compared with those over a gravel-bed stream without sediment depositions. An acoustic Doppler velocimeter was used to measure the instantaneous velocity of flows. The progressive infilling of void spaces in the gravel-bed stream forms distinct bimodal depositions that alter the mean flows characterised by increasing zero-velocity levels and massive damping in the bed shear stresses. The data plots of turbulent intensity depict enhancement of streamwise turbulent intensity in the near-bed flow region with increasing sand depositions. Moreover, the opposite nature of streamwise and vertical turbulent kinetic energy fluxes in the interfacial sublayer leads to slowing down the time-average Reynolds shear stresses at the vicinity of the gravel-bed surface. At the vicinity of the crest, the ejection and sweep events contributed approximately 86 and 56%, respectively, to the total Reynolds shear stress production in the case of gravel bed under clear-water flow conditions. By contrast, the contributions of turbulent sweep events increased over the sand-filled gravel bed at the same location.

Authors: De Oliveira Dantas Crislainny Dayanny 
Published: February 2024

A temática do gênero e sexualidade se mostra cada vez mais relevante, considerando o fortalecimento dos espaços de luta e resistência na atualidade. A escola, enquanto instituição que exerce controle sobre os corpos através da disciplinarização, deve estar atenta à essas questões e promover oportunidades iguais para os mais diversos estudantes. Sob essa perspectiva, este artigo tem como objetivo analisar o discurso produzido no Referencial Curricular do Ensino Médio Potiguar, no tocante à temática do gênero e sexualidade, como um dos Temas Contemporâneos Transversais, relacionando as relações de poder na construção dos sentidos e das vontades de verdade. Para tanto, utilizamos a Análise do Discurso como aporte teórico a partir dos estudos de Foucault (1988, 1995, 1998, 2004, 2008). Trata-se de um trabalho descritivo-interpretativo de caráter qualitativo. Usamos o método arqueogenelógico para análise do discurso que tem como corpus enunciados extraídos do Referencial Curricular do Ensino Médio Potiguar, documento normativo que orienta a práxis didático-pedagógica, formulado a partir da reforma do Ensino Médio. A análise nos permitiu constatar que a temática emerge nos Temas Contemporâneos Transversais do documento como estratégias de biopoder e regulamentação dos temas que envolvem à sexualidade no contexto escolar.

Intravoxel Incoherent Motion Diffusion-weighted Magnetic Resonance Imaging
combined with Texture Analysis in Predicting the Histological Grades of Rectal
Adenocarcinoma
Authors: Gao Fei , Zhou Jie , Cao Wuteng , Gong Jiaying , Wang Peipei , Wang Chuanbin , Fang Xin , Zhou Zhiyang 
Published: February 2024

Purpose::
To evaluate the predictive value of 3.0T MRI Intravoxel Incoherent motion diffusion-weighted magnetic resonance imaging (IVIM-DWI)
combined with texture analysis (TA) in the histological grade of rectal adenocarcinoma.

Methods::
Seventy-one patients with rectal adenocarcinoma confirmed by pathology after surgical resection were collected retrospectively. According to
pathology, they were divided into a poorly differentiated group (n=23) and a moderately differentiated group (n=48). The IVIM-DWI parameters
and TA characteristics of the two groups were compared, and a prediction model was constructed by multivariate logistic regression analysis. ROC
curves were plotted for each individual and combined parameter.

Results::
There were statistically significant differences in D and D* values between the two groups (P < 0.05). The three texture parameters
SmallAreaEmphasis, Median, and Maximum had statistically significant differences between groups (P = 0.01, 0.004, 0.009, respectively). The
logistic regression prediction model showed that D*, the median, and the maximum value were significant independent predictors, and the AUC of
the regression prediction model was 0.860, which was significantly higher than other single parameters.

Conclusion::
3.0T MRI IVIM-DWI parameters combined with TA can provide valuable information for predicting the histological grades of rectal
adenocarcinoma one week before the operation.
A Systematic Review and Meta-Analysis of MRI Radiomics for Predicting
Microvascular Invasion in Patients with Hepatocellular Carcinoma
Authors: Zhou Hai-ying , Cheng Jin-mei , Chen Tian-wu , Zhang Xiao-ming , Ou Jing , Cao Jin-ming , Li Hong-jun 
Published: February 2024

Background::
The prediction power of MRI radiomics for microvascular invasion (MVI) in patients with hepatocellular carcinoma (HCC) remains uncertain.

Objective::
To investigate the prediction performance of MRI radiomics for MVI in HCC.

Methods::
Original studies focusing on preoperative prediction performance of MRI radiomics for MVI in HCC, were systematically searched from databases
of PubMed, Embase, Web of Science and Cochrane Library. Radiomics quality score (RQS) and risk of bias of involved studies were evaluated.
Meta-analysis was carried out to demonstrate the value of MRI radiomics for MVI prediction in HCC. Influencing factors of the prediction
performance of MRI radiomics were identified by subgroup analyses.

Results::
13 studies classified as type 2a or above according to the Transparent Reporting of a Multivariable Prediction Model for Individual Prognosis or
Diagnosis statement were eligible for this systematic review and meta-analysis. The studies achieved an average RQS of 14 (ranging from 11 to
17), accounting for 38.9% of the total points. MRI radiomics achieved a pooled sensitivity of 0.82 (95%CI: 0.78 – 0.86), specificity of 0.79
(95%CI: 0.76 – 0.83) and area under the summary receiver operator characteristic curve (AUC) of 0.88 (95%CI: 0.84 – 0.91) to predict MVI in
HCC. Radiomics models combined with clinical features achieved superior performances compared to models without the combination (AUC:
0.90 vs 0.85, P < 0.05).

Conclusion::
MRI radiomics has the potential for preoperative prediction of MVI in HCC. Further studies with high methodological quality should be designed
to improve the reliability and reproducibility of the radiomics models for clinical application.
MRI Plain Scan: A Tool in the Management of Cervical Cancer during
Pregnancy
Authors: Gao Feng , Qian Ting , Sun Minghua , Lu Yuanyuan , Cheng Jiejun , Fu Le 
Published: February 2024

Objective::
The purpose of this study was to assess the diagnostic value of magnetic resonance imaging (MRI) in staging and treatment of cervical cancer in
pregnancy, and to evaluate the benefit of apparent diffusion coefficient (ADC) during neoadjuvant chemotherapy management.

Materials and Methods::
This was a retrospective cohort study. Patients were divided into two groups according to the stage of cervical cancer. The mean term of pregnancy
at the time of the diagnosis was the early second trimester (range 10-27 weeks) and the median age was 33 years (range 26-40 years). The
abdominal and pelvic MRI images and clinical data of these patients were reviewed. Tumor size, local tumor spread, and nodal involvement were
evaluated using an MRI dataset. The treatment and follow-up imaging were analyzed as well, and the ADC was measured before and after the
chemotherapy.

Results::
16 patients with histopathologically confirmed cervical cancer during pregnancy were retrospectively enrolled. 7 patients were diagnosed with
local cervical cancer (FIGO stage IAI) and designated as early stage group, as the lesion was invisible on MRI. In this group, pregnancies were
allowed to continue until cesarean delivery (CD) at 38-41 weeks. The other 9 patients presenting with local or extensive cervical cancer (FIGO
stage IB2-IIA2) were designated as the advanced-stage group. The lesion could be measured and analyzed on MRI. They were treated with neoadjuvant
chemotherapy in pregnancy. Among them, 6 patients underwent TP regimen (paclitaxel 135~175 mg/m2 plus cisplatin 70~75 mg/m2),
while 3 patients received TC regimen (paclitaxel 135~175 mg/m2 plus carboplatin AUC=5). NACT was performed for 1 to 2 courses before
surgery. ADC demonstrated significant differences before and after chemotherapy administered during pregnancy (1.06 0.12 sec/mm2 vs. 1.34
0.21 sec/mm2).

Conclusion::
MRI has been found to be helpful in staging cervical cancer in pregnancy. Patients with stage IA confirmed by MRI can choose conservative
treatment and continue the pregnancy until term birth. MRI can dynamically monitor the efficacy of chemotherapy for patients with stage IB and
above during pregnancy. ADC value can have a potential role in the evaluation of chemotherapy efficacy
Immunoglobulin G4 (IgG4)-related Lymphadenopathy in Submandibular Space
Mimicking Submandibular Malignant Tumor: A Case Report
Authors: Yang Go Eun 
Published: February 2024

Background::
Immunoglobulin G4 (Ig G4)-related disease is rare; however, it is a fibroinflammatory disease that has been studied a lot so far. Although the
expression pattern varies depending on the organ affected, it usually manifests as organ hypertrophy and organ dysfunction.

Case Presentation::
A 46-year-old man was referred to our otorhinolaryngology department for left submandibular swelling and tenderness that occurred 2 weeks ago.
He was treated with antibiotics (augmentin 625mg, per oral) for 2 weeks, but his symptoms did not improve, and his white blood cell (WBC) count
was 10,500 /μL (normal 3,800−10,000 /μL).

Conclusion::
A mass-like lesion of the submandibular space has been concluded and the laboratory findings have been satisfactory (IgG4 level); IgG4-related
disease, which is rare, but recently often reported, can be included in the differential diagnosis.

Posterior Pole in Immune Thrombocytopenic Purpura
Authors: Çavdarlı Cemal , Güvenç Hülya , Çomçalı Sebile , Coşkun Çiğdem , Alp Mehmet Numan 
Published: February 2024

Background::
Immune thrombocytopenic purpura (ITP) is a rare auto-antibody mediated disease of isolated thrombocytopenia (<100,000/μL) with normal
haemoglobin levels and leukocyte counts. Only a small number of ITP cases have been reported with accompanying ophthalmological findings.
Herein, we report an ITP case with demonstrative retinal haemorrhages.

Case Presentation::
A fifty-five-year-old woman with a known history of type 2 diabetes mellitus was referred to our clinic with blurred vision. After detailed
anamnesis and clinical assessment, she was diagnosed as primary ITP in haematology department, and systemic steroid (1.5mg/kg) therapy was
initiated. During her follow-up, a concomitant peripheral facial paralysis (PFP) emerged. In the course of follow-up, her platelet counts increased
gradually, the retinal haemorrhages regressed partially, and the PFP recovered completely.

Conclusion::
ITP is a rare haematologic disease that sometimes manifests with additional systemic involvements, and this disease should be remembered in the
differential diagnosis of unusual retinal haemorrhages, which might be the only presenting feature.
Primary Pulmonary Enteric Adenocarcinoma: Rare Imaging Findings
Authors: Xie Lixuan , Liu Zhijun , Chen Yousan 
Published: February 2024

Introduction::
Pulmonary enteric adenocarcinoma (PEAC) is an extremely rare variant of lung adenocarcinoma characterized by pathological features similar to
those of colorectal adenocarcinoma. It is mostly observed on computed tomography (CT) and positron emission tomography (PET)/CT as solitary
or multiple nodules/masses in the lung. It tends to grow rapidly and is difficult to distinguish from lung metastatic colorectal cancer. Herein, we
have presented a case of PEAC with special imaging findings.

Case Presentation::
A chest CT scan of a 72-year-old man with suspected chronic pneumonia revealed a well-defined consolidation in the upper lobe of the left lung.
The lesion was slightly enlarged at the 9-month follow-up, and low FDG accumulation was subsequently observed using 18F-fluorodeoxyglucose
(18F-FDG) PET/CT scans. The patient was later diagnosed with PEAC through percutaneous lung biopsy.

Conclusion::
Our case has demonstrated specific imaging findings of PEAC.
Iatrogenic Pseudoaneurysm with Acute Arterial Thrombosis in Multiple
Branches of the Lower Limbs Treated by Ultrasound-guided Thrombin
Injection: A Case Report
Authors: Gou Bo , Tu Bin , Xin Feng-Yue , Zhang Ji-Cheng , Wang Jie , Liu Jian 
Published: February 2024

Introduction::
With the development of vascular intervention, pseudoaneurysm complications are increasing. Ultrasound-guided thrombin injection (UGTI) is
currently the treatment of choice for pseudoaneurysm, but the pharmacological properties of thrombin may trigger acute thrombosis within the
vessel lumen. Despite a very low incidence, this type of primary arterial thrombosis is a serious complication of UGTI, and cases involving
multiple branches of the lower limb arteries are particularly rare.

Case Presentation::
Here, we report a case of a 65-year-old male who underwent UGTI for the treatment of an iatrogenic pseudoaneurysm of the femoral artery
complicated by acute thrombosis of multiple arteries in the lower limbs, and the patient ultimately underwent a successful thrombectomy.

Conclusion::
We reviewed the case and analyzed the possible etiologic causes, providing a reference for future clinical work.
The exploration of biochemistry laboratory activity: Study on higher education in Mataram
Authors: Anwar Yunita Arian Sani , Muti’ah Muti’ah 
Published: February 2024

As the core of science learning, laboratory work is inseparable from learning chemistry, including biochemistry. However, the implementation of laboratory work needs reconstruction, especially in higher education, so an initial study is needed to understand the problems in laboratory work at universities. This article was a study of the working conditions of the biochemistry laboratory at the University of Mataram. This study included quantitative research with students (N = 250), lab work assistants (N = 36), laboratorium staff (N = 4), and biochemistry lecturers (N = 4) as respondents. Techniques for obtaining data through participatory observation and questionnaires. Supporting data were obtained through interviews with students, lecturers, laboratory assistants, and laboratory personnel representatives. The results showed that the implementation of biochemistry lab work at the University in Mataram had gone through the pre-laboratory, laboratory work, and post-laboratory stages. Expository, inquiry, and demonstration are lab work methods, with 80% of the implementation using the expository method. Instructions related to waste handling have not been carried out in the implementation of biochemistry lab work. Based on these findings, several recommendations were put forward for improving the biochemistry lab work at the University.
Leveraging AI and Machine Learning to Develop and Evaluate a Contextualized User-Friendly Cough Audio Classifier for Detecting Respiratory Diseases: Protocol for a Diagnostic Study in Rural Tanzania
Authors: Isangula Kahabi Ganka , Haule Rogers John 
Published: February 2024

Background
Respiratory diseases, including active tuberculosis (TB), asthma, and chronic obstructive pulmonary disease (COPD), constitute substantial global health challenges, necessitating timely and accurate diagnosis for effective treatment and management.

Objective
This research seeks to develop and evaluate a noninvasive user-friendly artificial intelligence (AI)–powered cough audio classifier for detecting these respiratory conditions in rural Tanzania.

Methods
This is a nonexperimental cross-sectional research with the primary objective of collection and analysis of cough sounds from patients with active TB, asthma, and COPD in outpatient clinics to generate and evaluate a noninvasive cough audio classifier. Specialized cough sound recording devices, designed to be nonintrusive and user-friendly, will facilitate the collection of diverse cough sound samples from patients attending outpatient clinics in 20 health care facilities in the Shinyanga region. The collected cough sound data will undergo rigorous analysis, using advanced AI signal processing and machine learning techniques. By comparing acoustic features and patterns associated with TB, asthma, and COPD, a robust algorithm capable of automated disease discrimination will be generated facilitating the development of a smartphone-based cough sound classifier. The classifier will be evaluated against the calculated reference standards including clinical assessments, sputum smear, GeneXpert, chest x-ray, culture and sensitivity, spirometry and peak expiratory flow, and sensitivity and predictive values.

Results
This research represents a vital step toward enhancing the diagnostic capabilities available in outpatient clinics, with the potential to revolutionize the field of respiratory disease diagnosis. Findings from the 4 phases of the study will be presented as descriptions supported by relevant images, tables, and figures. The anticipated outcome of this research is the creation of a reliable, noninvasive diagnostic cough classifier that empowers health care professionals and patients themselves to identify and differentiate these respiratory diseases based on cough sound patterns.

Conclusions
Cough sound classifiers use advanced technology for early detection and management of respiratory conditions, offering a less invasive and more efficient alternative to traditional diagnostics. This technology promises to ease public health burdens, improve patient outcomes, and enhance health care access in under-resourced areas, potentially transforming respiratory disease management globally.

Análisis de las políticas de transformación digital de las microempresas en la región latinoamericana: los casos de Colombia y Chile
Authors: Barcia Lehmann Rodrigo , Martínez-Cárdenas Betty 
Published: February 2024

El objeto de este artículo es comprender cuál es la naturaleza y las implicaciones de las políticas de transformación digital de las microempresas en la región latinoamericana, en particular, respecto de los casos de Colombia y Chile. En efecto, debido a la pandemia causada por el virus SARS-CoV-2, que generó la enfermedad COVID-19 y las medidas de restricción de movimiento del año 2020, la transformación digital de las microempresas se hizo aún más urgente. Esta urgencia obedece a la necesidad de reactivar la economía, de un lado, pero también a la necesidad de regular internamente el Objetivo de Desarrollo Sostenible Núm. 9 (ODS9). Para ello, Chile y Colombia han transpuesto en la legislación interna todo un conjunto de políticas que han acelerado el uso de la tecnología. En especial, nos hemos detenido a analizar qué depara el futuro para las pequeñas empresas, o cómo las políticas públicas ayudarían a la incorporación de las nuevas tecnologías y al cumplimiento efectivo del ODS 9. Nuestra tesis es que para lograr una reglamentación efectiva en la promoción de las tecnologías emergentes para lograr que estas puedan ser utilizadas para reducir los costos de transacción y las externalidades respecto de las pequeñas empresas, la transposición del ODS9 es insuficiente. Este estudio emplea el método del derecho comparado para analizar algunos de los cambios generados en Chile y Colombia con respecto a las pequeñas empresas y analizará críticamente la técnica de transposición de los ODS. Las nuevas tecnologías pueden servir para trabajar legislativa y jurisprudencialmente sobre estas dos fallas de mercado y las consecuencias de ello merecen una reflexión en derecho comparado.
