classification

Coronavirus disease (COVID-19) is a viral pneumonia that is found in China and has spread globally. Early diagnosis is important for effective and timely treatment. Thus, many ongoing studies attempt to solve key COVID-19 problems such as workload classification, detection, and differentiation from other pneumonia and healthy lungs using different imaging modalities. Researchers have identified some limitations in the deployment of deep learning methods to detect COVID-19, but there are still unmet challenges to be addressed. The use of binary classifiers or building classifiers based on only a few classes is some of the limitations that most of the existing research on the COVID-19 classification problem suffers from. Additionally, most prior studies have focused on model or ensemble models that depend on a flat single-feature imaging modality without using any clinical information or benefiting from the hierarchical structure of pneumonia, which leads to clinical challenges, and evaluated their systems using a small public dataset. Additionally, reliance on diagnostic processes based on CT as the main imaging modality, ignoring chest X-rays. Radiologists, computer scientists, and physicians all need to come to an understanding of these interdisciplinary issues. This article first highlights the challenges of deep learning deployment for COVID-19 detection using a literature review and document analysis. Second, it provides six key recommendations that could assist future researchers in this field in improving the diagnostic process for COVID-19. However, there is a need for a collective effort from all of them to consider the provided recommendations to effectively solve these issues.

Background: In light of the COVID-19 pandemic and the health crisis left in its wake, our goal is to develop extensive machine-learning techniques to provide a clear picture of the treatment, and possible mistreatment, of specific patient demographics during hospital triaging.Objective: We aim to reveal whether a patient’s treatment and hospital disposition is related to the following attributes - Emergency Severity Index (ESI), gender, employment status, insurance status, race, or ethnicity which our 100 MB dataset included.Materials and methods: Our work is separated into two parts - the classification task and data analysis. As part of the classification task, we used the k-Nearest-Neighbor classifier, the F1-score, and a random forest. We then analyze the data using SHapley Additive exPlanations (SHAP) values to determine the importance of each attribute.Results: Our findings show that significance varies for each attribute. Notably, we found that patients with private insurance programs receive better treatment compared to patients with federal-run healthcare programs (e.g. Medicaid, Medicare). Furthermore, a patient’s ethnicity has a greater impact on treatment for patients under 40 years of age for any given ESI level. Surprisingly, our findings show language is not a barrier during treatment.Discussion and conclusion: We, therefore, conclude that although hospitals may not be doing so intentionally, there is a systemic bias in hospital triaging for specific patient demographics. For future works, we hope to aggregate additional patient data from hospitals to find whether specific demographics of patients receive better healthcare in different parts of the United States.

Objective: To evaluate the surgical management of myomas at the Teaching Hospital of Angré according to the FIGO (International Federation of Gynecology and Obstetrics) classification.Patients and methods: This was a cross-sectional study at the Teaching Hospital of Angre from January 1, 2020, to December 31, 2022. Patients whose operative indication was clearly identified were included in the study. Incomplete files were not included. The variables studied were anthropometric parameters, clinical characteristics of myomas, and surgery. Due to the large size and multifocal location of uterine myomas, the therapeutic option remained surgery by laparotomy.Results: Most patients were over 35 years old (71.5%) and nulliparous (52.8%). The first indication for surgery was menometrorrhagia (88.6%), followed by the desire for motherhood (37.8%) and dysmenorrhoea (20.2%) for myomas most often FIGO type 4 (p = 0.0031). Myomectomy under cervical-isthmic tourniquet was the most common procedure for FIGO type 4 myomas (66.1%; p = 0.0543). Hysterectomy was most frequently performed for FIGO type 7 myomas (43.9%; p = 0.0543). For myomectomy, the first complication was anaemia (3.5%) followed by uterine suture haemorrhage (1.7%) (p = 0.5139).Conclusion: Our surgical practice at the Teaching Hospital of Angre is in accordance with FIGO recommendations. However, an effort should be made to promote the minimally invasive surgical approach (laparoscopic, hysteroscopic, transvaginal ablation) for small fibroids (≤ 5 cm) or FIGO type 0 to 3, which is not very frequent in our current practice.

Hypersexual disorder, also known as compulsive sexual behavior or sex addiction, is a complex and clinically significant condition characterized by intense and recurrent sexual fantasies, urges, or behaviors that significantly disrupt an individual’s daily life and overall well-being. Despite its importance, hypersexual disorder remains a controversial and debated topic, lacking standardized diagnostic criteria in major classification systems.This review paper provides a comprehensive examination of hypersexual disorder, encompassing its definition, conceptualization, etiology, co-occurring conditions, effects on mental and physical health, assessment, treatment approaches, cultural and ethical considerations, and future research directions. By synthesizing information from existing literature and research, this review aims to deepen our understanding of hypersexual disorder and contribute to the development of evidence-based interventions.The review begins by exploring the evolution of the term “hypersexual disorder” and its current status in diagnostic classifications. It then delves into the potential etiological factors contributing to the development of hypersexual behaviors, including neurobiological, genetic, and psychosocial factors.Furthermore, the review discusses the common comorbidities associated with hypersexual disorder, emphasizing the importance of addressing co-occurring mental health conditions in treatment planning. The psychological and physiological effects of hypersexual behaviors on affected individuals are examined, underscoring the urgency of early intervention and comprehensive treatment.The assessment and diagnosis of hypersexual disorder are thoroughly examined, considering the challenges and methodologies involved in identifying and evaluating affected individuals. Cultural and ethical considerations are highlighted, stressing the significance of providing culturally sensitive and ethical care to diverse populations.In the context of treatment, the review discusses various therapeutic approaches, including psychotherapy, medication, support groups, and harm-reduction strategies. The need for evidence-based treatments tailored to hypersexual disorder is underscored while recognizing the challenges of developing standardized protocols in this evolving field.Finally, future research directions are outlined, focusing on the standardization of diagnostic criteria, prevalence studies, neurobiological investigations, and the integration of cultural competency in treatment approaches.In conclusion, this review paper aims to contribute to a comprehensive understanding of hypersexual disorder and its implications for affected individuals and society. By exploring the multifaceted aspects of the condition, this review seeks to provide insights into effective treatment approaches and inspire further research in the study of hypersexual disorder.

The article gives a general classification of non-invariant points in phase equilibrium diagrams of all possible types. The complete topological isomorphism of the diagrams of fusibility, solubility, and liquid-vapor equilibria in various sets of variables is demonstrated. The stability of mono-variant equilibria near the non-variant points is investigated. Recurrent formulas for calculating the number of topological elements of phase diagrams are given. A previously undescribed type of non-invariant points and phase processes in the solubility diagrams is described and characterized. The last ones have no topological analogs in other types of diagrams. Thus, we have carried out, as far as is available to the authors, a complete classification of invariant points and invariant processes in phase equilibrium diagrams of an arbitrary type and with an arbitrary number of components.

Background: CPTs are rare intraventricular papillary neoplasms derived from the choroid plexus epithelium. Anti-collagenase and extracellular matrix which have not been expressed in brain tumors. Objective: The purpose of this study was to investigate the expression levels of collagen type VI, anti-collagenase, laminin, MM9, claudins 1 and 5, N and E cadherins, and collagen VII, tejido, and collagen degradation enzyme complexes in choroid plexus tumors.Materials and methods: We studied the expression of adhesion molecules, extracellular matrix, and anticollagenase with an immunohistochemistry approach and electron microscopy analysis in 42 choroid plexus tumors. Results: 28(67%) were choroid plexus papillomas, 8 (19%) were atypical choroid plexus papillomas and 6 (14%) were choroid plexus carcinomas. The Ki67-li and MVD increased from CPC to ACPP, being the highest in malignant tumors as well as a strong immunoexpression of anti-collagenase and were inverse correlation with claudin 5, E, and N cadherin and collagen IV immunoexpressions which added further significant information to the prognosis and varied according to the histologic classification. By ultrastructure, the loss of basal membrane and cilia, disorganization, and proliferation of ECM were observed in CPC. Cerebral homeostasis largely results from the ability of both the Blood–Brain Barrier (BBB) at the brain microvascular endothelium and the Blood–Cerebrospinal Fluid Barrier (BCSFB) at the epithelium of the Choroid Plexuses (CPs), to control the composition of the CSF and cerebral extracellular fluid. Under expression of the tight junction proteins occludin, claudin-1 and claudin-5 are key molecular abnormalities responsible for the increased permeability of tumor endothelial tight junctions. Conclusion: The loss of basement membrane and ECM overexpression could be considered as a poor prognosis predictor in CPT. Anti-collagenase and MMP9 overexpression could be related to basal membrane and BBB plasticity in CPTs.

Cataracts may be described as the opacity of crystalline lenses present in the eye. The translucent crystalline lens is a part of the human eye. It possesses all the physical characteristics of a biconvex lens. The eye’s lens performs similar functions to a camera’s lens. The lens directs light rays entering the eye to the retina’s sensitive layers. Any factor that increases the absorption of scattering of light by the lens reduces its transparency. The opacity of the lens or its capsule, whether developmental or acquired, is called a cataract. Cataracts vary in degree of density and site and assume various forms. Cataract is the leading cause of reversible visual impairment and blindness globally. There are several classifications of cataracts based on morphologic and/or etiologic criteria. However, in epidemiologic studies, the simplified system of three types based on localization of lens opacities is most commonly used: Nuclear cataract is the most common type, followed by cortical cataract and posterior subcapsular cataract. This most prevalent form of acquired cataract, also known as an “age-related cataract,” affects people of both sexes equally and typically develops after age 50. More than 90% of people experience senile cataracts by age 70. Although one eye is almost always afflicted before the other, the disorder is typically bilateral. In the available literature, there is no mention of any such drug that could reverse the opacity of the lens (cataract) once it occurred and make it clear and transparent again.Only replacement of opaque lenses with artificial transparent Intraocular lens (IOL) is successful treatment of cataracts. This review focuses on senile cataracts and the best possible management of senile cataracts.

Science is the art of systematic and reproducible measurements, ultimately leading to knowledge supported by a holistic logic. Besides serendipity, there are 6 ways in general to obtain knowledge: authoritarianism; mysticism; rationalism, empiricism; pragmatism; and scepticism. Over the last 100 years, a canonical mythology – cortical spreading depression (CSD) – has prevailed in migraine pathophysiology. Conversely, a well-defined adaptive/protective role has evolved for CSD in locusts, Drosophila, and mammals. Additionally, an elaborate but entirely symptomatic nosologic system has arbitrarily evolved in migraine / primary headache. While the so-called systematic but symptomatic classification system of migraine / primary headache keeps on advancing the data-bank exponentially, the cause-effect nexus continues to obscure the most important systematic and insightful components of the knowledge of primary headache. The first step in advancing the cause-effect mystery of migraine / primary headache is to create a conceptual, consistent, and important adaptive-pathogenetic divide in the massive and disparate data-linked pathophysiology of the disorder. Once certain definitive principles (not laboratory/neuroimaging / genetic/epidemiologic data) emerge in the science of migraine / primary headache, we become empowered to understand the complex but key phenotypic blueprint as well as the neuro-pathophysiology / neuropsychiatry of the entity, including the visual (nasal visual-field sparing digitally-displaceable and eyeball-movement-synchronous scintillating scotomata), the lateralizing fronto-temporal-nuchal headache exclusively involving the ophthalmic division of the trigeminal nerve, and the associated features such as ‘stress’, ‘post-stress’, ‘autonomic storm’, ‘protean’ and ‘spontaneous’ onset and offset, and headache-aborting nausea-vomiting. In this manner, we have also evolved principles to begin to understand the most complex female predominance of migraine patients in adults [F:M=3:1] as well as the decline of prevalence in migraine attacks following menopause and advancing age. The Laws of the Pathophysiology of Migraine encompass the invaluable neurological / neuro-ophthalmological shift in pathophysiology from the brain to the eye.

Introduction: In the latest WHO classification of central nervous system tumors, Mitotic Index (MI) counted on Phosphohistone-H3 stained slides (pHH3-MI) has been suggested as a valid proliferative marker in various tumors including in the evaluation of meningioma grading.We aim to report our own experience in assessing the efficiency of the anti-pHH3 antibody as a grading tool for meningiomas.Methods: A retrospective study was conducted on a series of 40 meningiomas diagnosed from March 2020 to April 2021 at the Pathology Department of the Military Hospital of Tunis. We attempted immunohistochemistry and compared MI assessed on both pHH3 and HE-stained slides.Results: According to the HE-MI and pHH3-MI, the 40 cases of meningiomas were respectively divided into 35 versus 29 grade 1 cases, four versus eight grade 2 cases, and one versus three grade 3 cases. A highly significant correlation was found between pHH3-MI and HE-MI (p < 0.001). A significantly higher sensitivity in the pHH3 counting method was reported in our study. Discussion: we found, in accordance with the literature, that pHH3-MI is more reliable and accurate in mitotic counting, therefore exhibiting a high sensitivity in tumor grading, reported by an upgrade within 22,5% of the cases.Conclusion: PHH3-MI count facilitated a rapid reliable grading of meningiomas. However, molecular characteristics that could have a potentially significant impact on tumor progression should be the subject of further research.

To prepare the population for first aid in case of traumatic shock, algorithms for the fundamentals of didactics of the educational topic “First aid to the population in case of traumatic shock during accidents, disasters, natural disasters and terrorist attacks” of the subject “Life Safety” are proposed. 32 years of experience in teaching the subject in humanitarian state educational institutions of higher professional education of a non-medical profile in the city of Syktyvkar are summarized. Educational questions are considered: 1) The concept of shock; 2) Traumatic shock; 3) Mechanisms of injury that contribute to the development of traumatic shock. Predisposing factors. Complications. At-risk groups; 4) Classification, phases, and degrees of shock; 5) Universal first aid algorithm; 6) Basic anti-shock measures in the source of mass destruction and at the stages of evacuation; 7) Features of anti-shock measures in children; 8) Typical first aid mistakes for traumatic shock. For each of the educational issues considered, a summary of the material presented is given. Depending on the purpose of studying the topic, purpose, content of educational material, and form of organization of training, the number of hours allocated to its presentation and study in various forms of the educational process is established. Their distribution includes 1 lecture (2 hours), 1 seminar (2), 1 practical lesson (2), and 6 hours of independent work by students.

Objectives: This study aims to introduce and differentiate between traditional craze lines and a newly identified type of line in enamel, termed an “internal craze line.” This novel classification enhances diagnostic precision and carries significant clinical implications for treatment strategies. The goal is to provide a clear description of these two types of lines, discuss their unique clinical implications, and highlight their differing appearances and staining characteristics, contributing to improved understanding and management of enamel anomalies.Method and materials: Four extracted teeth exhibiting visible and internal craze lines were selected and examined using a stereo microscope to observe the structural characteristics of the lines. Cross-sections of the coronal parts of the teeth were prepared to document the differences between traditional craze lines (extending from the dentin-enamel junction [DEJ] to the enamel surface) and internal craze lines (originating at the DEJ but terminating midway through the enamel). Additionally, intraoral observations were conducted under high magnification to identify the visual differences between the two types of lines, noting that traditional craze lines can be stained while internal craze lines cannot.Results: Microscopic examination revealed two distinct types of lines: traditional craze lines extending from the DEJ to the enamel surface and internal craze lines terminating within the enamel. Intraoral observations confirmed that these lines could be distinguished under high magnification. Traditional craze lines appear as continuous lines reaching the enamel surface and can be stained, whereas internal craze lines are shorter, do not extend to the surface, and cannot be stained.Conclusion: The identification of internal craze lines presents significant clinical implications. Differentiating between traditional and internal craze lines can enhance diagnostic accuracy and inform treatment decisions. Recognizing internal craze lines might indicate different etiologies or risk profiles compared to traditional craze lines, influencing preventive and therapeutic strategies in dental practice. Further research is needed to explore the prevalence, causes, and long-term impacts of internal craze lines.

Fibrothecal tumors of the ovary are rare neoplasms, comprising less than 4% of all ovarian tumors and primarily affecting post-menopausal women. These benign tumors arise from the stromal tissue of the ovary and may produce hormones, particularly estrogen. Their diagnosis presents considerable challenges, frequently leading to misclassification as malignant ovarian tumors or uterine myomas. This report describes the case of a 59-year-old woman who presented with abdominal distension and pelvic pain. Clinical examination revealed a large, lobulated mass and imaging studies classified the right ovarian mass as ORADS 4. An exploratory laparotomy confirmed the absence of metastasis, resulting in total hysterectomy, bilateral adnexectomy, and omentectomy. The anatomopathological analysis identified the latero-ovarian mass as a fibrothecoma. Generally, fibrothecal tumors are benign with a favorable prognosis following surgical intervention. Common symptoms include pelvic pain and abdominal distension, and diagnosis typically relies on imaging techniques such as ultrasound and CT, with definitive confirmation achieved through histopathological examination. Given their potential to mimic malignant ovarian cancer, accurate diagnosis is critical and necessitates a multidisciplinary approach.

The integration of deep learning and genetic analysis has transformed the assessment of elite sports performance, particularly in competitive swimming. This study examines the fusion of deep learning techniques with DNA markers, physiological biometrics, and performance analytics to enhance the prediction and optimization of swimmer performance. A structured dataset comprising genetic sequences, physiological parameters, and biomechanical attributes was utilized to train a neural network model capable of categorizing swimmers based on genetic predisposition and athletic potential. The model achieved high classification accuracy, demonstrating a strong link between genetic markers, physiological traits, and competitive swimming outcomes. The findings emphasize the potential of AI-driven analytics in talent identification, customized training adaptations, and injury prevention. Furthermore, the study highlights the effectiveness of deep learning in analyzing complex genomic and physiological data to generate meaningful insights for performance enhancement. While the results validate the feasibility of using genetic and AI-based models for performance prediction, further studies are needed to broaden dataset diversity, integrate epigenetic influences, and test the model across varied athlete populations. This research contributes to the expanding field of AI-driven sports science and provides a solid foundation for incorporating genomics with deep learning to enhance elite athletic performance.

Meningiomas, classical extra-axial dural-based tumors of the meninges, have well-documented classical imaging features and signs on CT and MRI. Most meningiomas are classical lesions with prompt diagnosis on imaging and generally exhibit benign outcomes with slow growth patterns. The latest WHO classification of tumors in 2021 has classified 15 subtypes of meningiomas, and while classical meningiomas are WHO Grade 1 tumors, grading between varying subtypes varies between WHO Grades 1 and 3. The microcystic meningioma is a rare and atypical subtype of meningioma that has been sparsely documented in literature. In this case report, we revisit this rare subtype of meningioma with a brief review of literature.
