Abstract At the 2024 annual meeting of the Japanese Society for Dialysis Therapy (JSDT), a symposium on disaster preparedness in dialysis facilities was held, featuring a comprehensive report from Indonesia. Indonesia has a history of frequent disasters, including earthquakes, tsunamis, and floods caused by tropical cyclones. This article describes strategies and countermeasures designed to protect dialysis centers in Indonesia from the impacts of natural disasters. By recognizing the essential role these centers have in delivering life-sustaining treatment to individuals with end-stage kidney disease (ESKD) and examining existing protocols, disaster response plans, and lessons from past incidents, this article provides insights into proactive strategies that, perhaps, should facilitate protection of dialysis facilities and ensure continuity of care even amid adverse environmental conditions. During the preparation of this manuscript, an earthquake struck Myanmar on 28 March 2025, resulting in extensive damage that was reported worldwide. The regions surrounding Mandalay and Naypyidaw were particularly impacted. Prof. Kriang Tungsanga of the Nephrology Society of Thailand (NST) acted swiftly by obtaining information from a past president of the Myanmar Nephro-Urology Society (MNUS) and promptly contacted us on the Japanese side. Dialysis professionals from Japan, Thailand, and Myanmar had established collaborative ties through activities within the International Society of Nephrology (ISN) Oceania and Southeast Asia Regional Board, and the Japanese Society for Dialysis therapy international forum being held during the JSDT annual meeting. Through this network, dialysis supplies were urgently dispatched from Japan to the disaster-stricken areas in Myanmar. This paper chronologically outlines the methods and characteristics of international dialysis supply support to a conflict-affected country.
Repetitiveness measures reveal profound characteristics of datasets, and give rise to compressed data structures and algorithms working in compressed space. Alas, the computation of some of these measures is NP-hard, and straight-forward computation is infeasible for datasets of even small sizes. Three such measures are the smallest size of a string attractor, the smallest size of a bidirectional macro scheme, and the smallest size of a straight-line program. While a vast variety of implementations for heuristically computing approximations exist, exact computation of these measures has received little to no attention. In this paper, we present MAX-SAT formulations that provide the first non-trivial implementations for exact computation of smallest string attractors, smallest bidirectional macro schemes, and smallest straight-line programs. Computational experiments show that our implementations work for texts of length up to a few hundred for straight-line programs and bidirectional macro schemes, and texts even over a million for string attractors.
The pterygomandibular raphe (PMR) has traditionally been described as a fibrous or tendinous band connecting the bucinator (BM) and superior pharyngeal constrictor (SPCM) muscles. However, recent evidence has questioned its existence. This study aimed to reevaluate the anatomy of the pterygomandibular region by preserving fascial continuity and examining the relationships among adjacent muscles and connective tissues. Twenty-five sides from formalin-fixed cadaveric heads were examined. Twenty sides underwent macroscopic dissection under a surgical microscope, and five sides were sectioned axially and analyzed histologically using Masson's trichrome staining to assess muscle-fascia continuity. The buccopharyngeal fascia (BpF) adhered tightly to the posterolateral surface of the BM. A ligament-like bundle observed between the BM and medial pterygoid muscle corresponded to an artificial continuation of the BpF created by dissection. Axial sections revealed that the BpF, masseteric, and temporalis fasciae converged anteriorly on the lateral surface of the BM, while posteriorly, the BpF and temporalis fascia also merged, forming a confluence of fasciae. No discrete tendinous or ligamentous PMR was identified. The so-called PMR represents a dissection artifact rather than a true anatomical structure. These findings emphasize the importance of preserving fascial relationships and using precise terminology in anatomical and clinical contexts.
Background: The increasing popularity of mental-health information on social media platforms such as TikTok is raising concerns regarding misinformation. Previous research is limited to single disorders and videos in the English language only. Our objective was to investigate the quality of mental health information on German-language TikTok for a broader spectrum of disorders. Method: Thirty German-language TikTok-videos of each of the six most viewed hashtags on mental disorders (attention-deficit and hyperactivity disorder (ADHD), depression, autism, anxiety disorder, narcissism and post-traumatic stress disorder (PTSD)) were classified regarding authorship and rated either as "correct", "overgeneralized", "incorrect" or "subjective experience". The modified DISCERN (mDISCERN) and the Global Quality Scale (GQS) were used to rate reliability and quality of information for patients. Results: The 177 videos finally included in this study gathered a total of 94,348,220 views and 19.2% (n = 34) of the videos were rated as correct, 33.3% (n = 59) as incorrect, 18.1% (n = 32) as overgeneralized and 29.4% (n = 52) as personal experience. Chi-Square tests and Kruskal-Wallis tests showed significant relationships between either authorship or diagnosis and quality and reliability. Videos on PTSD and videos by expert authors showed the best and videos on narcissism and videos by laypeople the worst overall results. Conclusion: With around half of the analyzed videos supplying incorrect information, the quality of German-language TikTok mental health content is insufficient. Differences in the quality of content seem to be influenced by the topic and the authorship. Healthcare institutions and clinicians should be aware of this, educate patients accordingly, and could improve the quality of information by participating in online discourses.
