How I Do It: Holmium laser cystolitholapaxy and enucleation of the prostate for benign prostatic hyperplasia.

Holmium enucleation of the prostate (HoLEP) is a gold-standard, size-independent surgical treatment for benign prostatic hyperplasia (BPH) distinguished for its efficacy in tissue removal, shorter catheterization durations, lower transfusion rates, and decreased hospital stays when compared to transurethral resection of the prostate (TURP). The objective of this article is to demonstrate the step-by-step procedure of holmium laser cystolitholapaxy and enucleation of the prostate for BPH, emphasizing a top-down modified two-lobe technique with early apical release which enhances visualization and irrigation flow during the enucleation process.

Effects of Online Health Promotion Program to Improve the Health and Wellbeing of Healthcare Students: A Feasibility Study.

BACKGROUND: Healthcare students' health and wellbeing have been seriously affected worldwide. Research studies highlighted the need to establish health promotion strategies to improve them. METHODS: A mixed method feasibility with a randomized controlled trial study followed by qualitative focus-group interviews to evaluate the effect of a 24 h online health promotion program improving healthcare students' health and wellbeing was performed in mid-2022. The study also illustrated the program's effect, contents, and activity arrangements. Healthcare students from two large tertiary institutions were randomly assigned to intervention and waitlist-control groups. Outcomes were measured by self-completed online questionnaires at three-time points (baseline, week four, and week eight), and in-depth focus-group interviews followed. RESULTS: Among 70 enrolled and 60 eligible students, 54 completed the study, with a 10% attrition rate. Results demonstrated a significant difference between groups at week eight. Within the intervention group, there were significant differences were found from baseline to week eight for depression (p = 0.001), anxiety (p = 0.004), and stress (p < 0.001). The program also improved certain domains of personal wellbeing and quality of life. Qualitative findings further illustrated the program contents and activities' feasibility, acceptability, and suitability. Most participants welcomed the online mode's flexibility and convenience. They enjoyed diversified and complementary content and activities. They had increased self-awareness of health and wellbeing. Besides, mental health knowledge enables them to 'self-care' and help those in need in the future. CONCLUSIONS: The results indicate the feasibility of performing full-scale research in the future and may provide more support for the students of higher education institutions.

Updated Primer on Generative Artificial Intelligence and Large Language Models in Medical Imaging for Medical Professionals.

The emergence of Chat Generative Pre-trained Transformer (ChatGPT), a chatbot developed by OpenAI, has garnered interest in the application of generative artificial intelligence (AI) models in the medical field. This review summarizes different generative AI models and their potential applications in the field of medicine and explores the evolving landscape of Generative Adversarial Networks and diffusion models since the introduction of generative AI models. These models have made valuable contributions to the field of radiology. Furthermore, this review also explores the significance of synthetic data in addressing privacy concerns and augmenting data diversity and quality within the medical domain, in addition to emphasizing the role of inversion in the investigation of generative models and outlining an approach to replicate this process. We provide an overview of Large Language Models, such as GPTs and bidirectional encoder representations (BERTs), that focus on prominent representatives and discuss recent initiatives involving language-vision models in radiology, including innovative large language and vision assistant for biomedicine (LLaVa-Med), to illustrate their practical application. This comprehensive review offers insights into the wide-ranging applications of generative AI models in clinical research and emphasizes their transformative potential.

Efficacy and immunogenicity of a single dose of human papillomavirus vaccine compared to multidose vaccination regimens or no vaccination: An updated systematic review of evidence from clinical trials.

Objectives: This study systematically reviewed the published literature from clinical trials on the efficacy and immunogenicity of single-dose HPV vaccination compared to multidose schedules or no HPV vaccination. Methods: Four databases were searched for relevant articles published from Jan-1999 to Feb-2023. Articles were assessed for eligibility for inclusion using pre-defined criteria. Relevant data were extracted from eligible articles and a descriptive quality assessment was performed for each study. A narrative data synthesis was conducted, examining HPV infection, other clinical outcomes and immunogenicity responses by dose schedule. Results: Fifteen articles reporting data from six studies (all in healthy young females) were included. One article was included from each of three studies that prospectively randomised participants to receive a single HPV vaccine dose versus one or more comparator schedule(s). The other 12 articles reported data from three studies that randomised participants to receive multidose HPV vaccine (or control vaccine) schedules; in those studies, some participants failed to complete their allocated schedule, and evaluations were conducted to compare participants who actually received one, two or three doses. Across all efficacy studies, the incidence or prevalence of HPV16/18 infection was very low among HPV-vaccinated participants, regardless of the number of doses received; with no evidence for a difference between dose groups. In immunogenicity studies, HPV16/18 antibody seropositivity rates were high among all HPV-vaccinated participants. Antibody levels were significantly lower with one dose compared to two or three doses, but levels with one dose were stable and sustained to 11 years post-vaccination. Conclusions: Results from this review support recent World Health Organization recommendations allowing either one- or two-dose HPV vaccination in healthy young females. Longer-term efficacy and immunogenicity data from ongoing studies are awaited. Randomised trials of single-dose HPV-vaccination are urgently needed in other populations, e.g. boys, older females and people with HIV.
