Chronicling the Experiences of Life Sciences Teachers and Learners on the Usage of Enquiry-Based Learning in Enhancing Learners’ Academic Performance

Life sciences research provides critical insights into disease processes and allows for the development of novel treatments and innovative medical technologies, thereby directly improving human health and technology. Despite the widely acknowledged relevance of life sciences, there has been a long-term pattern of low performance. This is due to inefficient teaching methods, as how a lesson is delivered influences the learners' level of understanding, among other things. Hence, the present study examined the experiences of life sciences teachers and learners in using IBL to enhance the academic performance of life science learners. This study was underpinned by the interpretivism paradigm, a qualitative approach, and a participatory research approach. The study population consisted of all life sciences learners in a rural school in the Amathole West district, Eastern Cape province of South Africa, from which 2 life sciences teachers and 14 learners were conveniently sampled. Data were collected using interviews, observations, and document reviews, and they were analysed using thematic analysis. The research findings revealed that enquiry-based learning has the potential to foster the development of critical thinking, problem-solving, and communication skills among life sciences learners. However, several issues make it difficult to successfully implement enquiry-based learning in the context of teaching and learning life sciences, including a lack of resources, time constraints, misreading of instructions, a lack of support or supervision, and a lack of pedagogical topic expertise among teachers. The study concludes that enquiry-based learning, when done right, can help learners understand life sciences concepts deeper and remember what they have learnt for a longer period.

Clinical significance of platelet mononuclear cell aggregates in patients with sepsis and acute respiratory distress syndrome.

The diagnosis of sepsis combined with acute respiratory distress syndrome (ARDS) has increased owing to the enhanced awareness among medical professionals and the continuous development of modern medical technologies, while early diagnosis of ARDS still lacks specific biomarkers. One of the main pathogenic mechanisms of sepsis-associated ARDS involves the actions of various pathological injuries and inflammatory factors, such as platelet and white blood cells activation, leading to an increase of surface adhesion molecules. These adhesion molecules further form platelet-white blood cell aggregates, including platelet-mononuclear cell aggregates (PMAs). PMAs has been identified as one of the markers of platelet activation, here we hypothesize that PMAs might play a potential biomarker for the early diagnosis of this complication. To investigate the expression of PMAs in the serum of patients with sepsis complicated by ARDS and its clinical significance. We selected 72 hospitalized patients diagnosed with sepsis as the study population between March 2019 and March 2022. Among them, 30 patients with sepsis and ARDS formed the study group, while 42 sepsis patients without ARDS comprised the control group. After diagnosis, venous blood samples were immediately collected from all patients. Flow cytometry was employed to analyze the expression of PMAs, platelet neutrophil aggregates (PNAs), and platelet aggregates (PLyAs) in the serum. Additionally, the Acute Physiology and Chronic Health Evaluation (APACHE) II score was calculated for each patient, and receiver operating characteristic curves were generated to assess diagnostic value. The study found that the levels of PNAs and PLyAs in the serum of the study group were higher than those in the control group, but the difference was not statistically significant (P > 0.05). However, the expression of PMAs in the serum of the study group was significantly upregulated (P < 0.05) and positively correlated with the APACHE II score (r = 0.671, P < 0.05). When using PMAs as a diagnostic indicator, the area under the curve value was 0.957, indicating a high diagnostic value (P < 0.05). Furthermore, the optimal cutoff value was 8.418%, with a diagnostic sensitivity of 0.819 and specificity of 0.947. In summary, the serum levels of PMAs significantly increase in patients with sepsis and ARDS. Therefore, serum PMAs have the potential to become a new biomarker for clinically diagnosing sepsis complicated by ARDS.

Use of laser technologies in the treatment of hemorrhoids (Literature review)

Hemorrhoids are one of the most common diseases of the anorectal region, representing a serious medical and socio-economic problem that significantly affects the quality of life of patients. Surgical treatment of this pathology is necessary in cases where the patient complains of bleeding and prolapse of internal hemorrhoids, which cannot be treated with conservative methods. Traditional methods of surgical treatment of this pathology, despite their effectiveness, have a number of significant disadvantages, such as severe pain after surgery, prolonged healing of anal canal wounds, a long period of incapacity for work, as well as possible complications in the form of strictures of the anal canal, insufficiency of the rectal obturator, and anal fistulas. Recently, due to the active development of medical technology in the surgical treatment of hemorrhoids, many new minimally invasive treatment methods have appeared, including the use of lasers with different wavelengths, which have demonstrated high efficiency along with such advantages as reducing the intensity of postoperative pain syndrome, decreasing the frequency of intraoperative and early postoperative complications, as well as the possibility of outpatient implementation of these techniques. Depending on the stage of hemorrhoidal disease, as well as the type of laser radiation, various methods that affect one or both (vascular and mechanical) links in the pathogenesis of the disease are used. This article provides a review of modern literature data and analyzes the experience of using various lasers in the treatment of hemorrhoidal disease.

Device innovation in cardiovascular medicine: a report from the European Society of Cardiology Cardiovascular Round Table.

Research performed in Europe has driven cardiovascular device innovation. This includes, but is not limited to, percutaneous coronary intervention, cardiac imaging, transcatheter heart valve implantation, and device therapy of cardiac arrhythmias and heart failure. An important part of future medical progress involves the evolution of medical technology and the ongoing development of artificial intelligence and machine learning. There is a need to foster an environment conducive to medical technology development and validation so that Europe can continue to play a major role in device innovation while providing high standards of safety. This paper summarizes viewpoints on the topic of device innovation in cardiovascular medicine at the European Society of Cardiology Cardiovascular Round Table, a strategic forum for high-level dialogue to discuss issues related to the future of cardiovascular health in Europe. Devices are developed and improved through an iterative process throughout their lifecycle. Early feasibility studies demonstrate proof of concept and help to optimize the design of a device. If successful, this should ideally be followed by randomized clinical trials comparing novel devices vs. accepted standards of care when available and the collection of post-market real-world evidence through registries. Unfortunately, standardized procedures for feasibility studies across various device categories have not yet been implemented in Europe. Cardiovascular imaging can be used to diagnose and characterize patients for interventions to improve procedural results and to monitor devices long term after implantation. Randomized clinical trials often use cardiac imaging-based inclusion criteria, while less frequently trials randomize patients to compare the diagnostic or prognostic value of different modalities. Applications using machine learning are increasingly important, but specific regulatory standards and pathways remain in development in both Europe and the USA. Standards are also needed for smart devices and digital technologies that support device-driven biomonitoring. Changes in device regulation introduced by the European Union aim to improve clinical evidence, transparency, and safety, but they may impact the speed of innovation, access, and availability. Device development programmes including dialogue on unmet needs and advice on study designs must be driven by a community of physicians, trialists, patients, regulators, payers, and industry to ensure that patients have access to innovative care.

Cardiovascular disease, particularly myocardial infarction (MI) profound impact on patients' quality of life and places a substantial burden on the healthcare and economy systems. Developments in medical technology have led to the emergence of coronary intervention as an essential method for treating MI. To assess the effects of cardiac rehabilitation care on cardiac function recovery and negative emotions in MI after coronary intervention. This study included a total of 180 patients with MI during the period from June 2022 to July 2023. Selected patients were divided into two groups: An observation group, which receiving cardiac rehabilitation care; a control group, which receiving conventional care. By comparing multiple observation indicators such as cardiac function indicators, blood pressure, exercise tolerance, occurrence of adverse cardiac events, and negative emotion scores between the two groups of patients. All the data were analyzed and compared between two groups. There were 44 males and 46 females in the observation group with an average age of 36.26 ± 9.88 yr; there were 43 males and 47 females in the control group, with an average age of 40.87 ± 10.5 yr. After receiving the appropriate postoperative nursing measures, the results of the observation group showed significant improvement in several indicators compared with the control group. Indicators of cardiac function, such as left ventricular end-diastolic internal diameter and left ventricular ejection fraction were significantly better in the observation group than in the control group (P < 0.05). Exercise endurance assessment showed that the 6-minute walking test distance was significantly increased in the patients of the observation group (P < 0.01). In addition, the incidence of adverse cardiac events was significantly lower in the observation group, and negative mood scores were significantly reduced (P < 0.05). Cardiac rehabilitation care after coronary intervention has a significant positive impact on functional recovery. This emphasizes the importance of cardiac rehabilitation care to improve patient recovery.

Electronic Medical Record and Smoking Cessation Activities: Literature Review

Vital information regarding the life and health of a patient is gathered in medical records. The electronic medical record (EMR) is the product of medical record information technology development. Electronic health records and other health information systems have the potential to be useful tools for raising the caliber and efficacy of clinical interventions aimed at reducing tobacco consumption. Electronic medical records are used by doctors, clinics, and health care organizations to track patient smoking cessation outcomes and as a smoking cessation support tool. Thirteen papers from the Google Schoolar database and the reference lists of the included research were used in the review. We looked for research that was written between 2010 and 2020. Overall, these trials discovered that only slight benefits were made by several doctor-recommended therapies related to tobacco use. Following modifications to electronic medical records intended to speed up the collection and management of tobacco use during medical visits, there seems to have been a rise in the documentation of tobacco status and referrals for cessation counseling. To maximize the potential of EMRs for extra therapeutic advantages and smoking cessation in hospital settings, more research is required.

Multimodal Distillation Pre-training Model for Ultrasound Dynamic Images Annotation.

With the development of medical technology, ultrasonography has become an important diagnostic method in doctors' clinical work. However, compared with the static medical image processing work such as CT, MRI, etc., which has more research bases, ultrasonography is a dynamic medical image similar to video, which is captured and generated by a real-time moving probe, so how to deal with the video data in the medical field and cross modal extraction of the textual semantics in the medical video is a difficult problem that needs to be researched. For this reason, this paper proposes a pre-training model of multimodal distillation and fusion coding for processing the semantic relationship between ultrasound dynamic Images and text. Firstly, by designing the fusion encoder, the visual geometric features of tissues and organs in ultrasound dynamic images, the overall visual appearance descriptive features and the named entity linguistic features are fused to form a unified visual-linguistic feature, so that the model obtains richer visual, linguistic cues aggregation and alignment ability. Then, the pre-training model is augmented by multimodal knowledge distillation to improve the learning ability of the model. The final experimental results on multiple datasets show that the multimodal distillation pre-training model generally improves the fusion ability of various types of features in ultrasound dynamic images, and realizes the automated and accurate annotation of ultrasound dynamic images.

Medical Negligence with Special Reference to Act of Commission and Omission: A Narrative Review

A doctor’s failure to uphold the standards of his profession, causing the death of a patient whom the doctor hoped to save, is known as medical negligence. The most embarrassing act one can commit is medical negligence, which usually results in the patient’s death. Legally, medical negligence is a breach of the duty of care leading to harm. Lack of clinical competence can be interpreted as negligence. Indian courts decide cases of medical negligence based on the Bolam test. According to Black’s Law Dictionary, negligence is defined as “conduct, action, or omission, which may be declared as negligence without any argument or proof as it violates the dictates of common prudence”. The three cardinal elements in negligence are duty of care failure, failure to exercise duty of care (Dereliction), and causation of damage to the patient on account of dereliction. References to medical negligence can be found in classical texts such as Manusmriti, Kotilya Arthashastra, Charaka Samhita, Sushruta Samhita, and others. To mitigate medical negligence, various measures can be taken, such as improved communication, strengthening training and education, emphasising quality assurance, and legal reforms. The rapid development of medical science and technology has proven to be a powerful tool for doctors to better diagnose and treat patients, but it has also become a tool to exploit people for profit. Accurate information about negligence and its laws is needed as there is not enough data in this regard. To avoid medical negligence, practitioners should show strict adherence to modern surgical ethics, which also include concepts like the importance of informed consent, doctor-doctor relationship, doctor-patient relationship, doctor-state relationship, doctor-attendant relationship, attendantpatient relationship, and patient autonomy.

Early Detection of Parkinson's Disease Using Deep NeuroEnhanceNet With Smartphone Walking Recordings.

With the development of digital medical technology, ubiquitous smartphones are emerging as valuable tools for the detection of complex and elusive diseases. This paper exploits smartphone walking recording for early detection of Parkinson's disease (PD) and finds that walking recording empowered by deep learning is a valid digital biomarker for early-recognizing PD patients. Specifically, the inertial sensor data is preprocessed, including normalization, scaling, and rotation, and then the processed data is fed into the proposed deep NeuroEnhanceNet. Finally, determine the individual prediction score using the PD-prone strategy and generate the detection results. The proposed deep NeuroEnhanceNet, specifically designed for inertial sensor data, can focus on both the long-term data characteristics within a single channel and the inter-channel correlations. Our method obtains a low false negative rate of 0.053 for the early detection of PD. We further analyze and compare the effectiveness of digital biomarkers captured from the walking and resting processes for early detection of PD. All the code for this work is available at: https://github.com/heyiyia/NeuroEnhanceNet.

Polarization properties of partially coherent mixed dislocation beams transmitting in biological tissues

&lt;sec&gt; &lt;b&gt;Objective&lt;/b&gt; The optical information change of beams acting on biological tissue can get an insight into the new optical effects of tissue, and even can provide a theoretical basis for developing biphotonic medical diagnosis and therapy technologies. Polarization technology is also widely used in the field of biological detection due to its advantages of non-contact, rich information and without staining markers. In this work, the polarization behaviors of partially coherent screw-linear edge mixed dislocation beam transmitting in biological tissue are analyzed and explored. Simultaneously, in order to more clearly and more intuitively understand a mixed dislocation beam, both the normalized intensities and phase distributions at source plane for different parameters &lt;i&gt;a&lt;/i&gt; and &lt;i&gt;b&lt;/i&gt; are also discussed. We hope that the obtained results will provide theoretical and experimental foundation for expanding the application of singularity beams in biological tissue imaging technology.&lt;/sec&gt;&lt;sec&gt; &lt;b&gt;Method&lt;/b&gt; By combining the Schell term with the field distribution of the screw-linear edge mixed dislocation beam at the source plane, and based on the generalized Huygens-Fresnel principle, the analytical expressions of the cross-spectral density matrix elements of partially coherent screw-linear edge dislocation beam propagating in biological tissues are derived. Adopting the unified theory of coherence and polarization, the polarization behaviors of the beams can be investigated in detail.&lt;/sec&gt;&lt;sec&gt; &lt;b&gt;Results&lt;/b&gt; At the source plane, the intensity has a non axisymmetric distribution, and there exists a coherent vortex with a topological charge size of 1 and a linear edge dislocation. The sign of &lt;i&gt;a&lt;/i&gt; is related to the rotation direction of the phase singularity. The larger the value of &lt;i&gt;b&lt;/i&gt;, the farther the linear edge dislocation is from the origin. At the source plane, the degree of polarization and ellipticity between the two identical points are independent of the four parameters: dimensionless parameter &lt;i&gt;a&lt;/i&gt;, off-axis distance of edge dislocation &lt;i&gt;b&lt;/i&gt;, spatial self-correlation length &lt;i&gt;σ&lt;/i&gt;&lt;sub&gt;&lt;i&gt;yy&lt;/i&gt;&lt;/sub&gt;, and spatial mutual-correlation length &lt;i&gt;σ&lt;/i&gt;&lt;sub&gt;&lt;i&gt;xy&lt;/i&gt;&lt;/sub&gt;, the orientation angle is only independent of &lt;i&gt;a&lt;/i&gt; and &lt;i&gt;σ&lt;/i&gt;&lt;sub&gt;&lt;i&gt;xy&lt;/i&gt;&lt;/sub&gt;; the polarization of two different points is independent of &lt;i&gt;a&lt;/i&gt; and &lt;i&gt;b&lt;/i&gt;, but is related to &lt;i&gt;σ&lt;/i&gt;&lt;sub&gt;&lt;i&gt;yy&lt;/i&gt;&lt;/sub&gt; and &lt;i&gt;σ&lt;/i&gt;&lt;sub&gt;&lt;i&gt;xy&lt;/i&gt;&lt;/sub&gt;. In transmission, the polarization degrees and ellipticity of two different points fluctuate greatly and the orientation angle displays less fluctuation. Finally, all the polarization state parameters tend to be their corresponding values, respectively.&lt;/sec&gt;&lt;sec&gt; &lt;b&gt;Conclusions&lt;/b&gt; The results show that when &lt;i&gt;b&lt;/i&gt; is smaller, the linear edge dislocation is paraxial and plays an important role in the polarization state change; when &lt;i&gt;b&lt;/i&gt; is larger, the polarization state changes of the screw-linear edge mixed dislocation beam will tend to be the pattern of spiral beams. The absolute value of the difference between &lt;i&gt;σ&lt;/i&gt;&lt;sub&gt;&lt;i&gt;yy&lt;/i&gt;&lt;/sub&gt; and &lt;i&gt;σ&lt;/i&gt;&lt;sub&gt;&lt;i&gt;xy&lt;/i&gt;&lt;/sub&gt; is also one of main factors influencing the polarization state. The sign of &lt;i&gt;a&lt;/i&gt; does not affect the change in polarization state, but its magnitude can influe the change of speed. Due to more complex factors determining the correlation fluctuations between different points in the light field, the changes of two different points are more sensitive than those of the two identical points in shallow biological tissue. Beams with different parameters can be selected for different application requirements.&lt;/sec&gt;

ИСТОРИЧЕСКИЙ АНАЛИЗ, ОЦЕНКА И ГЛОБАЛЬНЫЕ ТЕНДЕНЦИИ ОЖИДАЕМОЙ ПРОДОЛЖИТЕЛЬНОСТИ ЗДОРОВОЙ ЖИЗНИ

The expected duration of a healthy life (hereinafter referred to as the life expectancy) estimates the number of years that a person is expected to live with good health. This concept is important to take into account the quality of life, not just its duration. Sullivan’s method of assessment of HPP combines data on mortality and health status. However, there are limitations such as subjectivity in the definition of “healthy”, data quality, and complexity of interpretation. Historically, the criterion of HPA has evolved, taking into account improvements in health and social conditions, including a more complete assessment of aspects of health and quality of life. Globally, there is a positive trend associated with the development of healthcare and medical technologies. There are differences in HPP between developed, developing and African countries. In Russia, there are also differences in health insurance by region related to socio-economic factors, access to medical care and lifestyle. Cities have a higher rate of HPP than rural areas and individual regions such as Siberia and the Caucasus. The analysis of the literature data revealed positive changes in healthy life expectancy in various countries. Japan, South Korea, the Scandinavian countries, Costa Rica, Iceland, Australia, Norway, and New Zealand showed significant increases in HDI associated with improved health care, socio-economic conditions, and health promotion programs. However, in Russia, problems such as health inequalities and health infrastructure constraints pose obstacles. Effective preventive measures, vaccinations, health promotion and lifestyle improvements are key factors in improving the world’s health. It is important to influence the social, economic and environmental aspects of health, strengthen health systems and promote healthy lifestyles for sustainable improvement of the HHS. Objective: to carry out a historical analysis, identify trends in the change of the GPI indicator and the main factors that contribute to the improvement of this indicator. Methods of work: critical analysis of scientific literature. Results: a review of the literature on the study of OPCW is conducted and the main factors of the change in OPCW are presented. Scope of application: proof of the need for the use of the indicator of the HPP. Summary conclusions: The analysis of global trends in HHS highlights the importance of continuous efforts to improve access to health care, socio-economic conditions, public health measures and lifestyle choices.

An On-Board Executable Multi-Feature Transfer-Enhanced Fusion Model for Three-Lead EEG Sensor-Assisted Depression Diagnosis.

The development of affective computing and medical electronic technologies has led to the emergence of Artificial Intelligence (AI)-based methods for the early detection of depression. However, previous studies have often overlooked the necessity for the AI-assisted diagnosis system to be wearable and accessible in practical scenarios for depression recognition. In this work, we present an on-board executable multi-feature transfer-enhanced fusion model for our custom-designed wearable three-lead Electroencephalogram (EEG) sensor, based on EEG data collected from 73 depressed patients and 108 healthy controls. Experimental results show that the proposed model exhibits low-computational complexity (65.0K parameters), promising Floating-Point Operations(FLOPs) performance (26.6M), real-time processing (1.5s/execution), and low power consumption (320.8mW). Furthermore, it requires only 202.0MB of Random Access Memory(RAM) and 279.6KB of Read-Only Memory(ROM) when deployed on the EEG sensor. Despite its low computational and spatial complexity, the model achieves a notable classification accuracy of 95.2%, specificity of 96.9%, and sensitivity of 94.0% under independent test conditions. These results underscore the potential of deploying the model on the wearable three-lead EEG sensor for assisting in the diagnosis of depression.

Photoplethysmography for Assessing Microcirculation in Hypertensive Patients After Taking Antihypertensive Drugs: A Review.

High blood pressure (BP) is a common disease and is associated with many chronic diseases. Measuring BP is essential for the treatment and management of many diseases, and therefore there is a growing need for a non-invasive, sleeveless and continuous BP monitoring device. With the development of technology, pulse waveform analysis using photoplethysmography (PPG) has become more feasible for evaluating BP. This study aimed to evaluate the changes of vascular elasticity and blood volume over time by using the characteristic parameters extracted by PPG. We reviewed the latest progress and literature on the observation of capillary network characteristics in hypertensive and non-hypertensive patients by PPG, the influence of different drugs on microcirculation characteristics in hypertensive patients with PPG, and further explored the key relationship between microcirculation and hypertension. We found that the PPG waveform produced by the fingertips of hypertensive patients is very different from that of healthy people, and the PPG waveform changes significantly during diastolic period after antihypertensive treatment. With the rapid development of medical technology, people can get more intuitive microcirculation image data, which provides beneficial help for the comprehensive understanding of hypertension.
