Shock Wave Therapy in the Treatment of Erection Dysfunction: How to Define Clinical Outcomes? A Comparison Between Penile Doppler Ultrasound and a New Visual Erec-tion Hardness Score (V-EHS) During a Blinded, Sham-Controlled Trial.

In the last decade, several studies have proven the effectiveness of low-intensity shock waves (LI-ESWT), but with several factors that make it difficult to carry out systematic reviews. To demonstrate the effectiveness of LI-ESWT and define the best tool for routine clinical assessment of erectile dysfunction. Twenty-one participants with purely vasculogenic erectile dysfunction were selected and randomized to LI-ESWT or placebo. All patients underwent evaluation with The International Index of Erectile Function (IIEF-5), V-EHS (new visual scale), and standardized penile doppler ultrasound before and after shock wave therapy. LI-ESWT has proven effective in the treatment of moderate erectile dysfunction, and the new V-EHS has demonstrated greater accuracy than Doppler in the diagnosis and follow-up of erectile dysfunction. Using the IIEF-5 as a control tool, we observed a clinical response after 1 month, with a greater increase in the shock wave therapy arm of +3.21 points compared to + 0.57 in the sham group. At six months, the treated group showed a mean increase of 4.71 points compared to baseline (p = 0.006), while those who received sham therapy had a decrease (case = +4.71 points vs. sham control = -1.0, p = 0.006). Based on this observed difference, we performed a comparative analysis between the V-EHS and penile doppler ultrasound to observe whether the test results corroborated the IIEF-5 findings. The correlation between V-EHS and IIEF-5 in the therapy group in the pre-therapy period was strong (r = 0.816, p < 0.001), and at 6 months it increased to very strong (r = 0.928, p < 0.001). Penile Doppler ultrasound did not show the same correlation strength with IIEF-5, presenting a moderate correlation at 6 months (Pearson correlation score = 0.540), as also demonstrated in the ROC curve through the V-EHS AUC = 0.963 (p = 0.001) vs. Doppler AUC = 0.713 (p = 0,290). Strengths and Limitations: The main strengths of the present study are the blinded, randomized, placebo-controlled clinical trial and the comparison between penile Doppler and a new visual classification for erection hardness score. The limitations are the number of patients and the short follow-up. LI-ESWT has proven effective in the treatment of moderate vasculogenic erectile dysfunction, with optimal results at 6 months. The new V-EHS offers a simple, reliable and reproducible assessment of erectile function.

Web Application for Retrieval-Augmented Generation: Implementation and Testing

The purpose of this paper is to explore the implementation of retrieval-augmented generation (RAG) technology with open-source large language models (LLMs). A dedicated web-based application, PaSSER, was developed, integrating RAG with Mistral:7b, Llama2:7b, and Orca2:7b models. Various software instruments were used in the application’s development. PaSSER employs a set of evaluation metrics, including METEOR, ROUGE, BLEU, perplexity, cosine similarity, Pearson correlation, and F1 score, to assess LLMs’ performance, particularly within the smart agriculture domain. The paper presents the results and analyses of two tests. One test assessed the performance of LLMs across different hardware configurations, while the other determined which model delivered the most accurate and contextually relevant responses within RAG. The paper discusses the integration of blockchain with LLMs to manage and store assessment results within a blockchain environment. The tests revealed that GPUs are essential for fast text generation, even for 7b models. Orca2:7b on Mac M1 was the fastest, and Mistral:7b had superior performance on the 446 question–answer dataset. The discussion is on technical and hardware considerations affecting LLMs’ performance. The conclusion outlines future developments in leveraging other LLMs, fine-tuning approaches, and further integration with blockchain and IPFS.

Cyberbullying and Depression among Chinese Youth

Cyberbullying is the use of electronic communication to harass, insult, or cause harm to a person via the Internet. Cyberbullying has become more prevalent in todays society, and young people who experience it frequently feel isolated and helpless, potentially contributing to the rising rate of depression. However, little research has been conducted on the depression caused by cyberbullying among Chinese high school students. Therefore, this study focuses on the current state of depression among Chinese high school students and its correlation with age, gender, and city level. The questionnaire used was a modified Chinese version of the CES-D scale and was distributed via social media to 184 current Chinese high school students from various regions. After conducting a pilot study, the language of the Chinese version of the CES-D scale has been adjusted to become more understandable for students. Participants filled out an online questionnaire, and SPSS was used to analyse the data. Male students have a slightly lower average total depression score (M = 62.74) than female students (M = 65.71). There was no correlation between gender and student depression. Furthermore, there is no significant correlation between school location and depression levels (p = 0.084, p &gt; 0.05). In addition, the overall Pearson correlation score indicates that depression and age are correlated with a weak association of 0.178 and a significance of 0.016 (p = 0.016, p &lt; 0.05).

Online Learning Readiness, Motivation, and English Learning Achievement in Higher Education

The present study aimed at investigating the correlations between online learning readiness (OLR) and motivation (M) toward English learning achievement (ELA). The study employed a correlational design by gathering quantitative data from 35 first-semester students at the English Education Department at a public university in Indonesia. The data were collected by distributing the OLR questionnaire, which was adapted from the Online Learning Readiness Scale (OLRS) developed by Hung et al. (2010), administering a motivation questionnaire adapted from Gardner’s (2004) Attitude/Motivation Test Battery (AMTB), and documenting the students’ midterm test scores, which represented their ELA. The researchers used Pearson product-moment correlation reliability to identify how well the test items correlated with the other variables. The data were then analyzed using SPSS 23 version. The result shows that the students exhibited OLR in “ready” level and “very high” motivation level to learn at the time of the research implementation. Both OLR and motivation had positive correlations with students’ ELA. OLR was strongly correlated to ELA with r=0.647 (sig.=0.000). Meanwhile, motivation had a lower Pearson correlation score (r=0.497, sig.=0.002) that showed a moderate correlation toward ELA. Hence, OLR contributed more to ELA than motivation.

Developing a Large Benchmark Corpus for Urdu Semantic Word Similarity

The semantic word similarity task aims to quantify the degree of similarity between a pair of words. In literature, efforts have been made to create standard evaluation resources to develop, evaluate, and compare various methods for semantic word similarity. The majority of these efforts focused on English and some other languages. However, the problem of semantic word similarity has not been thoroughly explored for South Asian languages, particularly Urdu. To fill this gap, this study presents a large benchmark corpus of 518 word pairs for the Urdu semantic word similarity task, which were manually annotated by 12 annotators. To demonstrate how our proposed corpus can be used for the development and evaluation of Urdu semantic word similarity systems, we applied two state-of-the-art methods: (1) a word embedding–based method and (2) a Sentence Transformer–based method. As another major contribution, we proposed a feature fusion method based on Sentence Transformers and word embedding methods. The best results were obtained using our proposed feature fusion method (the combination of best features of both methods) with a Pearson correlation score of 0.67. To foster research in Urdu (an under-resourced language), our proposed corpus will be free and publicly available for research purposes.

Shared Decision-Making in Pancreatic Surgery.

The objective of this study is to determine the factors influencing pancreatic surgery patients' perceptions of the shared decision-making process (SDM). Decision-making in pancreatic surgery is complicated by the risk of morbidity and mortality and risk of early recurrence of disease. Improvement in SDM has the potential to improve the receipt of goal- and value-concordant care. This cross-sectional survey included patients who underwent pancreatic surgery. The following components were studied in relation to SDM: modified satisfaction with decision scale (SWD), modified decisional regret scale (DRS), quality of physician and patient interaction, and the impact of quality of life (FACT-Hep). Correlations were computed using Pearson's correlation score and a regression model. The survey completion rate was 72.2% (of 40/55) and the majority (72.5%) of patients underwent pancreaticoduodenectomy. There were significant positive relationships between the SDM measure and (DRS, SWD; r = 0.70, P < 0.001) and responses to questions regarding how well the patient's actual recovery matched their expectations before treatment (r = 0.62, P < 0.001). The quality of the physician-patient relationship correlated with how well recovery matched expectations (r = 0.53, P = 0.002). SDM measure scores were significant predictors of the decision evaluation measure (R2(adj) = 0.48, P < 0.001), FACT-Hep (R2(adj) = 0.15, P < 0.001), and recovery expectations measure (R2(adj) = 0.37, P < 0.001). Improved SDM in pancreatic surgery is associated with more realistic recovery expectations, decreased decisional regret, and improved quality of life.

In-house pre-prepared broth microdilution plates: A simple, cheap and pragmatic approach for susceptibility testing of colistin

Background: With the upsurge in multi-drug resistant Gram-negative bacilli, it is imperative to optimize and standardize the antibiotic susceptibility testing (AST) methods for polymyxins (colistin & polymyxin B). The long overdue confusion regarding the susceptibility testing of colistin was put to rest in 2016 when the CLSI-EUCAST joint Polymyxin Breakpoint Working Group recommended broth microdilution (BMD) in polystyrene plates as the reference method for AST. Though several commercially-available BMD plates have been assessed by EUCAST, the high cost of such commercial plates during contemporary times hinder their use in routine microbiological laboratories especially in low and middle income countries. Thus, a suitable alternative to commercial BMD plates should be sought for to ensure a cost-effective, rapid and reliable reporting of AST of colistin. Methods and materials: With the aim of reducing this redundancy in the workflow, we designed an experiment to charge several microtiter plates with the drug dilution and the media on day 0, storing them frozen at −200C and then retrieving them sequentially for AST (henceforth called pre-prepared frozen BMD plates (PFBP). The PFBP were charged with same representative organisms on every 2–4 days for two months to check for the reliability of AST reporting. Essential agreement (EA), categorical agreement (CA), very major error (VME) and major errors (ME) were computed in accordance with ISO standard 20776-2. For validation, the criteria of EA3 90%, CA 3 90%, VME £1.5% AND ME£3% was used. Pearson correlation and Cohen's kappa (k) score was calculated using GraphPad (San Diego, CA, USA). Results: For colistin, EA and CA of PFBP was 97.5% and 98.3%, respectively. For polymyxin B, EA and CA of PFBP was 99.1% and 90%. Further, the performance of PFBP for colistin susceptibility testing of A. baumannii in the present study (EA=97.5%, CA=98.3%) was superior to five commercial plates available and evaluated by EUCAST. Conclusion: Based on these observations, we propose that pre-prepared frozen BMD plates can be incorporated in routine workflow of microbiological laboratory as reliable, cheap and rapid method for susceptibility testing of colistin.
