Abstract Background We evaluated the microbiota in the stomach of Gastroesophageal Reflux Disease (GERD) patients. We compared Erosive Reflux Disease (ERD) to gastritis and Non-erosive Reflux Disease (NERD) subjects by 16S rRNA approach on gastric biopsy specimens. A total of 197 subjects were included consisting of gastritis (68; 34.52%), ERD (55; 27.92%), and NERD (74; 37.56%). After quality filtering, 187 samples were included for OTU analysis using Qiime2. Results We observed a significant difference in alpha diversity (Shannon and Simpson indexes were P = 0.0016 and P = 0.017, respectively). A significant decrease in alpha diversity index was observed in NERD with Helicobacter pylori (H. pylori)-positive subjects than in gastritis (Simpson index P = 0.022; Shannon index P = 0.029), indicating a significant influence of H. pylori on the diversity in the stomach despite the diseases. In H. pylori-negative samples, alpha diversity measurement by the abundance coverage estimates (ACE) and Fisher Test revealed that ERD had significantly lower richness than gastritis and NERD groups (P = 0.00012 and P = 0.00043, respectively). Anaerobacillus sp. could only be found in ERD patients by LEFse analysis. Conclusions The presence of ERD could alter microbiome diversity. A negative correlation between H. pylori and ERD is shown in this microbiome study but not in NERD.

The present study aimed to synthesize hydroxyapatite (HAp) from milkfish (Chanos chanos) bone by simple heat treatments ranging from 600 to 800 °C. The yield and color of synthesized powders before and after heat treatment were analyzed. The synthesized powders were characterized using Fourier transform infrared spectroscopy (FTIR) to identify the functional groups and X-ray diffraction (XRD) was employed to identify phase and crystallinity properties. This study found that the yield percentages were found to be approximately 50%. The FTIR characteristics exhibited the phosphate and carbonate groups at high temperatures (≥600 °C). In general, this study confirmed that the well-crystallized HAp can be synthesized by thermal treatment at a temperature of 160 °C for 48 h.

The Corona-Virus Disease 2019 (COVID-19) pandemic has affected all levels of society and has had a disruptive effect on all aspects of life, including education. Additionally, it puts a strain on the ability of medical educationists to adapt to this unique situation. Clinical mentors and students from all health-related fields are considered potential carriers when considering hospital-based education. On the other hand, the current economic crisis is reviving the need for online learning opportunities and virtual education programs. Most medical schools respond to lockdown by shifting to live online or video-based learning, which is becoming increasingly popular. In the face of a pandemic, maintaining standards in medical education, keeping clinical learning on track, and minimizing assessment disruption are all difficult tasks to accomplish. This new environment requires adaptation in order to better prepare future clinicians for their roles. In this research paper, the authors design an immersive medical learning platform to emphasizes the importance of virtual education and the potential consequences of integrating the immersive experience of extended reality (XR) into medical education for the future of clinical competency learning and assessment in the healthcare education field. This platform can run on PCVR and mobile VR devices. We have designed and developed a medical simulation scenario using the considerations of medical educators or doctors to ensure that the platform we designed can provide an immersive experience to increase the effectiveness of online teaching and learning activities.
