ChatGPT as a Source for Patient Information on Patellofemoral Surgery—A Comparative Study Amongst Laymen, Doctors, and Experts

Introduction: In November 2022, OpenAI launched ChatGPT for public use through a free online platform. ChatGPT is an artificial intelligence (AI) chatbot trained on a broad dataset encompassing a wide range of topics, including medical literature. The usability in the medical field and the quality of AI-generated responses are widely discussed and are the subject of current investigations. Patellofemoral pain is one of the most common conditions among young adults, often prompting patients to seek advice. This study examines the quality of ChatGPT as a source of information regarding patellofemoral conditions and surgery, hypothesizing that there will be differences in the evaluation of responses generated by ChatGPT between populations with different levels of expertise in patellofemoral disorders. Methods: A comparison was conducted between laymen, doctors (non-orthopedic), and experts in patellofemoral disorders based on a list of 12 questions. These questions were divided into descriptive and recommendatory categories, with each category further split into basic and advanced content. Questions were used to prompt ChatGPT in April 2024 using the ChatGPT 4.0 engine, and answers were evaluated using a custom tool inspired by the Ensuring Quality Information for Patients (EQIP) instrument. Evaluations were performed independently by laymen, non-orthopedic doctors, and experts, with the results statistically analyzed using a Mann–Whitney U Test. A p-value of less than 0.05 was considered statistically significant. Results: The study included data from seventeen participants: four experts in patellofemoral disorders, seven non-orthopedic doctors, and six laymen. Experts rated the answers lower on average compared to non-experts. Significant differences were observed in the ratings of descriptive answers with increasing complexity. The average score for experts was 29.3 ± 5.8, whereas non-experts averaged 35.3 ± 5.7. For recommendatory answers, experts also gave lower ratings, particularly for more complex questions. Conclusion: ChatGPT provides good quality answers to questions concerning patellofemoral disorders, although questions with higher complexity were rated lower by patellofemoral experts compared to non-experts. This study emphasizes the potential of ChatGPT as a complementary tool for patient information on patellofemoral disorders, although the quality of the answers fluctuates with the complexity of the questions, which might not be recognized by non-experts. The lack of personalized recommendations and the problem of “AI hallucinations” remain a challenge. Human expertise and judgement, especially from trained healthcare experts, remain irreplaceable.

Chronic Deltoid Insufficiency in Stage IV Adult Acquired Flatfoot Deformity: Do We Have a Good Answer?

Stage IV adult acquired flatfoot deformity (AAFD) with secondary chronic deltoid ligament insufficiency is a challenging deformity to treat, with minimal consensus in the literature concerning its surgical management. Many surgical treatment options have been described, including joint-sparing techniques, fusions, osteotomies, and even arthroplasties. However, questions remain as to what, if any, treatment is optimal. This contribution reviews studies on surgical treatments for stage IV AAFD with deltoid ligament failure and provides a critical analysis regarding the quality of outcomes reported for those different treatment options. PubMed and Google Scholar databases were searched between June 1, 2022, and August15, 2022, for studies published between 1990 and 2022 that describe the treatment of stage IV AAFD with deltoid ligament insufficiency. Articles included in the study focused on subjects with stage IV AAFD and associated deltoid ligament insufficiency undergoing surgical correction. Exclusion criteria included stage I, II, and III AAFD, as well as deltoid ligament repair following acute injury/rupture. Nine studies covering five different treatment options for patients with stage IV AAFD and chronic deltoid insufficiency were included, with minimal overlap in outcome measures used to assess the efficacy of the procedure. Triple arthrodesis with deltoid ligament reconstruction resulted in a 62.5% (5/8) success rate with a residual tibiotalar (TT) angulation of 2°(success defined as <3°). Tibiotalar arthrodesis of four patients resulted in an average post-operative tibiotalar angulation of 4.8°with all patients showing progressive destabilization of the hindfoot complex at 12-18 year follow-ups. Deltoid arthroscopic laminoplasty (Brostrom) resulted in an increased American Orthopaedic Foot and Ankle Society (AOFAS) score from 49.7 pre-op to 91.9 post-op. There was no long-term follow-up of these patients. Deltoid ligament reconstruction using autografts of the peroneus longus resulted in a post-operative valgus of 2.1°in one study and <5°in another. Deltoid ligament reconstruction using an anterior tibial tendon autograft resulted in a gain of 126.4 + 40.2% in stiffness compared to an intact ligament. Twinfix suture anchors resulted in a post-operative hindfoot angle averaging 5.3°. Combined deltoid and spring ligament reconstruction resulted in a 5.1°valgus angulation. There is currently no standard of care or clinical consensus regarding surgical treatment for stage IV AAFD with deltoid insufficiency. Several studies imply that mild valgus malalignment around the tibiotalar joint can result in satisfactory outcomes. A few studies even deemed <5°of valgus tilt post-operatively successful. However, it has been described that any imbalance in tibiotalar tilt is a significant risk factor for progressive arthritis and future ligamentous failure. No treatment option was able to correct valgus tilt to an anatomical standard (i.e., to normal anatomy). These varied findings, along with the lack of consensus on post-surgical measures to assess efficacy, are worrisome and emphasize the need for better surgical options. Moreover, there is a critical need for additional research on the long-termoutcomes following stage IV AAFD and deltoid insufficiency repair, particularly, as over five million people in the United States and 10% of the geriatric population are affected by AAFD with a risk of progressing to stage IV.

Chemical semantics: the evolution of meaning of the atom throughout the evolution of chemical science

Semantics is the study of meaning. And what does the meaning mean? We will consider the idea that a sign, whether sound or graphic, awakens in people as a good answer. Meaning, like language, is not a static, immutable thing, on the contrary it is constantly evolving. If this does not happen, the meaning ceases to exist and, consequently, the sign as well. A historical example in chemistry is phlogiston, which once proved incapable of opening doors to the future was shelved. The same happened with caloric, murium and others that had meanings not supported by new scientific knowledge. Meaning can change, take new forms, expand the field of meaning to adapt to contemporary knowledge. The atom gives us a magnificent example of meaning in movement capable of adapting to the new achievements of science. The search for understanding matter is undoubtedly a continuous process and one of the most enigmatic in science, an example of this is the evolutionary process suffered by models aiming to describe the atom. There were many philosophers who thought about the constitution of matter, but Leucippus, Democritus, Epicurus and Lucretius were the most visible. Thus, the study of the evolution of the meaning of the atom is the central aspect that will be addressed in this article.

PDE4D single nucleotide polymorphism rs918592 is associated with ischemic Stroke risk in Chinese populations: a meta-analysis

BackgroundSeveral studies have investigated the correlation between phosphodiesterase 4D (PDE4D) single nucleotide polymorphism (SNP) rs918592 and the risk of ischemic stroke (IS) in Chinese populations. But the results were inconsistent and inconclusive. Therefore, to resolve this conflict, we conducted a meta-analysis to further elucidate their relationship in Chinese populations.MethodsStudies focused on SNP rs918592 and IS risk were electronic searched in the databases of PubMed, Embase, ISI Web of Science, Weipu, China National Knowledge Infrastructure (CNKI), Chinese Biomedical (CBM) and Wanfang. The association between SNP rs918592 and IS risk was expressed by odds ratio (OR) with its confidence interval (CI). Begg’s and Egger’s linear regression tests were used to assess publication bias. The meta-analysis was performed with STATA 11.0 statistical software. Two online prediction websites (HaploReg and RegulomeDB) were adopted to explore the functions of SNP rs918592.ResultsThe meta-analysis ultimately included 10 studies involving 2,348 cases and 2,289 controls. The results showed that there was a significant correlation between SNP rs918592 and IS risk in Chinese individuals. The G allele had reduced risk of developing IS compared to the A allele (OR 0.83, 95% CI 0.74–0.95, P = 0.005). HaploReg and RegulomeDB analyses suggested that SNP rs918592 and its strongly linked SNPs (e.g. rs34168777) might have regulatory functions.ConclusionThis study shows that SNP rs918592 in PDE4D may be a contributor of IS risk in Chinese populations. It offers a good answer for the association of PDE4D SNP rs918592 with IS risk in Chinese populations for the first time.

Stavovi i mišljenja studenata prve godine medicine o učenju histologije i embriologije uz pomoć vršnjačkog podučavanja - uloga studenata demonstratora

Peer-assisted learning (PAL) is a form of teaching method where students facilitate the transfer of knowledge to other students and at the same time learn themselves. Department of Histology and Embryology at the Faculty of Medicine, University of Belgrade, Serbia has a longstanding tradition of PAL, which involves the use of undergraduate teaching assistants (UTAs) in practical microscopy classes. This research aimed to evaluate the attitudes and opinions towards UTAs work during Histology and Embryology course from the perspective of 1st year students. Data from this study were collected from 512 undergraduate medical students enrolled in the 1st study year using an anonymous semi-structured questionnaire. The analysis of the students' responses has shown that almost all of our students asked for the help of UTAs during Histology and Embryology course. Additionally, 65% of students said that they felt more comfortable asking UTAs for help during their labs than faculty teachers. Most students believe that UTAs devoted sufficient time to them during the practical classes. Nearly 90% of students agreed that UTAs gave them good advice and answers and more than 80% of students perceived that they had never received inaccurate information from UTAs. More than 40% of students can see themselves in the role of UTAs in future. These results indicate that UTAs have a significant place in the Histology and Embryology curriculum and that their role in everyday teaching represents one of the most important aspects of PAL.

Parents' Perceptions of the Learning System During the Covid-19 Pandemic at SMA Negeri 8 Longgar, Aru Islands Regency

The purpose of this study was to find out how parents perceived the learning system during the Covid-19 pandemic in SMA Negeri 8 Loose students. This study collected data through interviews, observation and documentation using a qualitative methodology. The findings of this study suggest that parents' perceptions of a good answer are that they can hang out with their children to strengthen their bond and personally monitor their children while they are learning. Parents expressed concern that online learning during the Covid-19 outbreak was impacting the quality of their children's learning. Meanwhile, the children's positive responses indicated that online learning was fun because someone was always there to help them when they had assignments from the teacher. The negative response is that students struggle to understand the teacher's assignment. As a result, parents must provide additional encouragement and attention to their children so that their learning activities continue to run smoothly even if they are not in front of the teacher as usual.

Knowledge of recommended antibiotic treatments for community-acquired infections in general medical practice: a cross-sectional study in Occitanie region, France

To assess and analyse the knowledge of recommended antibiotic treatments, focusing on the appropriate drugs and treatment durations for the most common community-acquired infections in general medical practice in Occitanie region, France. A web-based survey was conducted over a 3-month period, from October, 2018 to January, 2019. All participants answered directly through the online platform. For the analysis of overtreatment risk, a score based system was adopted and two scores were produced: the duration score and the treatment score. 413 general practitioners completed the survey. The overall rate of concordance with guidelines in terms of both drug choice and treatment length was 2974/4956 (60%) answers. Diseases with at least 70% good answers included cystitis, group A streptococcal pharyngitis, and bacterial superficial skin infections. Diseases with fewer than 50% good answers included pyelonephritis, dog bite wounds, and community-acquired pneumonia in patients aged ≥ 65 years. Factors associated with the risk of overtreatment were age > 40 years, country setting and hospital employment. Knowledge of treatment durations is satisfactory with 60% of recommendations being met. However, varying levels were observed according to different diseases. This study highlighted a very high rate of adherence when recommendations were clear. In contrast, low levels of adherence were observed when recommendations were ambiguous or when conflicting guidelines existed.

The Utilization of Artificial Intelligence Based Chatbot in Interactive Learning Media

Abstract: After the spread of the COVID-19 virus, the world of learning is no longer the same as it was before the pandemic, especially at the university level, which requires students to be more active in finding lots of learning references via the internet.

MATER: Bi-level matching-aggregation model for time-aware expert recommendation

Community question answering (CQA) websites have grown rapidly, but they face a gap between questions and answerers. This gap causes delays in getting answers and overwhelms potential answerers. Expert recommendation (ER) can bridge this gap by providing suitable answerers for the newly posted questions in time. However, most ER methods have some limitations. First, they focus on the representation of a user’s interest, but they ignore their ability to give high-quality answers (user expertise). Second, they do not consider that the answerers’ interests and expertise may change over time. Third, they only use the accepted answer as a good example, but they ignore other good answers that are not accepted. To address these issues, we propose MATER, a Bi-level Matching-Aggregation Model for Time-Aware Expert Recommendation to address these issues. MATER utilizes a matching-aggregation framework at two levels of sentence and question. MATER first matches the target question with each question in the user’s profile by a sentence-level matching-aggregation model. Next, the question matching results are aggregated by a proposed multi-perspective time-aware aggregation layer that considers both time-aware interest and expertise of a user. We propose to employ a listwise loss function to train our model, which takes into consideration all potential experts in the ranking strategy. Experimental results on six real-world CQA datasets from different domains demonstrate that MATER significantly outperforms state-of-the-art ER methods.

Why the Moral Equality Account of Hypocrisy Does Not Fail After All

The Moral Equality Account of Hypocrisy (ME) is a prominent theory of why hypocrites lack moral standing to blame. Hypocrites make exceptions for themselves and thereby implicitly deny moral equality, which is an essential premise of moral standing to blame. ME has recently faced challenges from philosophers who deny that it is the hypocrite’s rejection of moral equality that causes her to lose moral standing to blame. I have distinguished three main challenges which I discuss and rebut in this article: “The Internal Blame and Blame of Fictional Characters Challenge”, which I attribute to Todd (2019), and “The Hypercrite Challenge” and “The Inegalitarian Norm Challenge”, which are due to Lippert-Rasmussen (2021). The article begins by offering an account of ME. It fills in a few gaps in the theory, by explaining why it is necessary for a blamer to invoke a special right to blame and by determining the type of right that standing to blame is. It also distinguishes between the question of why hypocrisy is wrong or bad, and the question of why it undermines moral standing to blame. I hold that several theories provide plausible answers to the first question, but only ME has so far given a good answer to the second question. When distinguishing properly between these two questions, we see that ME can respond satisfactorily to the three challenges.

Receiving the right political system for afghanistan

This research, which has focused on finding a suitable political system for Afghanistan, has described discussions such as (explaining the concept of political system and structure, parliamentary system, advantages and disadvantages of parliamentary system, presidential system, advantages and disadvantages of parliamentary system and criticism of the current political system of Afghanistan). At the beginning of the research, we will get acquainted with the familiar discussion of the political system and structure, the comparison of the parliamentary system and the presidential system. In the era of globalization, countries experienced different systems from the centralized presidential system to the decentralized federal system, which in their nature have opponents and but the case and goal we are looking for is to get the right system, most of the scientists and writers expressed their opinion that the parliamentary system was more efficient in most of the countries that are transitioning towards modern democracy, compared to the centralized presidential system. End and the result that magnifies the current research is that the parliamentary system and the presidential system each have their own positive and negative points (advantages and shortcomings) that both of these systems are now clearly experienced in most countries of the world, which is a good example. The presidential system can be seen in the United States and a good example of the parliamentary system can be seen in the British political structure. But! The experiences gained from the experience of the parliamentary system in the majority of countries indicate that a non-centralized parliamentary system can be a good answer in the discussion of good governance and the experience of modern democracy in multi-ethnic and multi-racial societies like Afghanistan. According to the theory of separation of powers, the parliamentary system has better flexibility than the presidential system, which can prevent the tension between the two main branches of government (legislature, executive) and bring stability to most societies.

Pelatihan Canva sebagai Alternatif Media Pembelajaran Digital Berbasis Paradigma Merdeka Belajar untuk Guru SD Negeri 1 Purwogondo

The development of information and communication technology has brought influence in various fields of life including in the field of education. For this reason, educators in the Kurikulum Merdeka are required to continue to be creative and innovative in making or looking for creative and interesting learning media references. The Canva training held at SD Negeri 1 Purwogondo aims to introduce and train teachers to be skilled in using the Canva platform to create learning media. There are 3 stages in this training, namely the preparation, implementation, and evaluation stages. The preparation phase was carried out in coordination with SD Negeri 1 Purwogondo. The implementation stage consists of 2 core activities, namely material presentation by resource persons and training as well as guidance on making learning media using Canva. After the training stage, it was continued by giving questionnaires to the participants as a form of evaluation. The implementation of Canva training activities went well and provided benefits for teachers. The content of the material is considered good and relevant, with a satisfaction level of 67%. The resource persons are considered to have a good understanding and are able to convey the material clearly which is shown in the results of the questionnaire with a percentage of 79% very good in delivering material and 61% of good answers in the discussion / question and answer session. However, there were some suggestions from participants regarding the lack of time allotted for material delivery and for discussion/question and answer.

Comparing the responses of countries and National Health Systems to the COVID-19 pandemic: a critical analysis with a case-report series.

This review aimed to compare the different responses of countries to the pandemic, their National Health Systems, and their impact on citizens' health. This work aimed to create a narrative plot that connects different discussion points and suggests organizational solutions and strategic choices in the face of the pandemic. In particular, this work focused on public health organizations, specifically the European Union and vaccination politics. It is also based on a case report series (about the United States, Germany, Vietnam, New Zealand, Cuba, and Italy), where each country has responded differently to the pandemic in terms of political decisions such as vaccination type, information to citizens, dealings with independent experts, and other specific country factors. In comparing the various models of care systems response to the pandemic, it emerges that: we have found some (few) good practices, but without global coordination, and this is obviously not enough. It is now quite clear that there cannot be a "good answer" in a single nation. Uncoordinated local responses cannot counter a global phenomenon. The second point is that the general context must be considered from a strategic point of view. With the threat of new pandemics (but also of health disasters linked to climate change, pollution, and wars), humanity finds itself at the crossroads between investing in a "democratic" management of international bodies but without power (and at the mercy of the need for funds with consequent conflicts) or in some new leadership proposals that advocate efficiency and problem-solving (and that would probably be able to implement it) but that would place processes totally outside of the public's control.

Bringing Birth back down to Earth

ABSTRACT In The Birth of Ethics, Philip Pettit carefully argues that Erewhonians would develop concepts that closely resemble our normative concepts – including our moral concepts – and that this reveals a great deal about the nature of normativity in general and morality in particular. The purported revelations about morality include: Thesis #1: Moral concepts ascribe natural properties. Thesis #2 “Full-scale” moral realism is true. Thesis #3: There is a sufficiently good answer to the question, “Why be moral?” In this paper, I do not question Pettit's ingenious argument that the Erewhonians' conceptual repertoire would expand in the way described in his narrative. I instead question whether this narrative supports these metaethical theses. I argue that if our moral concepts were expressively equivalent to Erewhonian moral concepts, that would not ground a “full-scale” moral realism, nor would it give us a sufficiently compelling answer to the question “Why be moral?” Furthermore, I argue that our moral concepts are not expressively equivalent to Erewhonian moral concepts, which puts pressure on the argument that our moral concepts ascribe natural properties. Finally, contra Pettit, I argue that moral concepts do not play the same function in our lives as the analogous concepts play in Erewhonians' lives.

Sensitivity analysis index to determine the optimal location of multi-objective UPFC for improvement of power quality parameters

Today, advanced technologies are used for the reliable operation of power systems. In order to access a reliable and practical function in the systems, it is necessary to use precise control systems with higher efficiency in the systems to minimize the problems of the distribution system. Devices that are made on the basis of power electronics have wide applications in power systems today. These devices, which are called FACTS devices, provide the possibility of improving energy transmission with the least investment cost, as well as quick control of power system problems. FACTS devices are placed in series, parallel or series-parallel transmission lines and control the operation of distribution systems in permanent states as well as the dynamic behavior of the system in transient states. FACTS devices are an effective method to solve the problems and limitations of lines. Transmission and replacement networks are used to create new lines in the network. From the point of view of power distribution control, FACTS controllers can be placed anywhere in the transmission line, but the elements are most effectively used when they are placed at the most critical point. Unified Power Flow Controller (UPFC) is one of the most important FACTS devices that can improve parameters. The quality of power used in the power system depends on the effect of this controller in improving the loss reduction, reducing the total harmonic distortion (THD), and removing the clogged lines to their proper location in the power system. This device is capable of all different effective parameters at a time. These parameters usually include voltage, impedance, and phase. This paper uses a new sensitivity analysis index to determine the optimal size and location of the UPFC to improve the power quality parameters of the distribution system. The proposed method is evaluated on the IEEE 14-bus network in the Simulink environment of MATLAB software. Finally, according to the simulation results and the results obtained from the base network, it is determined that using the proposed sensitivity analysis index in UPFC location, losses Network, total harmonic distortions (THD) and eclipses Network lines are much improved. The results indicate that the proposed method has provided a good answer to determine the optimal size and location of UPFC to improve power quality parameters. Using the results of the sensitivity analysis method, the best place to install UPFC in the power grid, mode number 6 between buses 2 and 11 is obtained. and The amount of network power losses after sensitivity analysis, compared to the base network Active losses of about 55% and reactive losses of about 11% deceased, Due to the circular structure of the network, the current passing through the lines is different depending on the amount of load in the bases near that line, and with the presence of UPFC, the network is optimized and the current passing through the lines is also reduced. 4) Percentage of total harmonic distortion (THD) mains voltage before the presence of UPFC is about 27.12%, which after installation in the 6th place with a maximum size has been reduced to about 11.11%.

Performance Analysis and Development of QnA Chatbot Model Using LSTM in Answering Questions

This research aims to evaluate the performance of a Long Short-Term Memory (LSTM) based chatbot in answering questions (QnA). LSTM is a type of Recurrent Neural Network (RNN) architecture specifically designed to overcome vanishing gradient problems and can store long-term information. The method used is 5-fold cross-validation to train the chatbot model with 15 epochs at each fold using the dataset provided. The results showed variations in model performance at each fold. At the 5th fold, there was a decrease in performance with 84.63% accuracy, 96.36% precision, 64.9% recall, and 69.84% loss value. This finding shows that there is variability in the performance of the QnA chatbot model at each fold. In conclusion, the LSTM chatbot model can provide good answers with high accuracy and precision. Still, performance variations need to be considered in the use of this chatbot.

Inclusive dignity.

The idea of dignity is pervasive in political discourse. It is central to human rights theory and practice, and it features regularly in conceptions of social justice as well as in the social movements they seek to understand or orient. However, dignity talk has been criticized for leading to problematic exclusion. Critics challenge it for undermining our recognition of the rights of non-human animals and of many human individuals (such as children, the elderly, and people with disabilities). I argue that, on a plausible articulation of it, the idea of dignity does not lead to these exclusions and that it in fact helps defend an appropriately inclusive moral and political treatment of all individuals. Difficult issues about equality and diversity indeed arise, but a dignitarian approach can provide good answers to them or at least help make them clearer and more tractable.
