What drives Chinese youth to use fitness-related health information on social media? An analysis of intrinsic needs, social media algorithms, and source credibility
Authors: Zhang Xin , Tang Qing Qing , Cai Ying Ying 
Published: December 2024

IntroductionThe role of social media in providing fitness-related health information has been widely discussed; however, there is a notable lack of research on fitness-related health information behaviors among youth within the social media context. This study aims to address this gap by integrating Self-Determination Theory (SDT)-based internal factors and external factors (social media algorithms and source credibility).MethodsA voluntary sample of 600 participants, aged 15 to 29, was recruited. Data were analyzed using Partial Least Squares-Structural Equation Modeling (PLS-SEM) to examine the relationships between variables.ResultsThe analysis revealed that all three intrinsic needs—competence, autonomy, and relatedness—along with social media algorithms and source credibility, positively correlated with fitness-related health information use behaviors among youth. Additionally, social media algorithms moderated the relationship between the need for relatedness and fitness-related health information behavior.DiscussionThese findings provide new insights into developing health communication strategies on social media, particularly targeted toward the youth demographic, enhancing our understanding of effective health information dissemination in digital environments.

Published: December 2024

AimGustatory function plays a fundamental role in various aspects related to nutrition and health, and the decline in taste perception can result in a series of adverse consequences. This is expected with aging due to a decrease in taste buds and other conditions, leading to systemic and oral diseases. We aimed to compare taste sensitivity in the elderly population vs. adults.MethodsThis systematic review was reported according to PRISMA guidelines. The search was performed in four databases, as well as in grey literature. The risk of bias was assessed using the JBI's critical appraisal tools for observational studies. A meta-analysis with subgroups according to each flavor was conducted to obtain differences in means for adults vs. elderly (random-effects model).ResultsOut of the 5,660 studies retrieved, 18 observational studies were included, representing a total of 1,680 aged 18–59 years and 1,048 aged ≥ 60 years. Elderly individuals need higher concentrations to distinguish flavors compared to adults. In a qualitative analysis, all flavors showed differences between the groups, with sweet flavor being the easiest to recognize and the thresholds between the groups not being highly discrepant. However, in the meta-analysis, statistical differences were observed for sweet, salty, and umami flavors, while there were no statistical differences for sour and bitter flavors between the groups.ConclusionsThere are significant differences for distinguishing sweet, salty, and umami flavors between adults and elderly. Bitter and sour flavors did not exhibit differences in elderly.Systematic Review Registrationhttps://www.crd.york.ac.uk/prospero/display_record.php?RecordID=463873, PROSPERO (CRD42023463873).
Online communities as arenas of “amateur expertise”: examples from the social media activity for justice for Roman Zadorov
Authors: Lev-On Azi 
Published: December 2024

IntroductionThis study examines online communities as arenas where diverse forms of expertise converge to influence discourse and public opinion. Using the case of social media activism advocating for justice in the wrongful conviction of Roman Zadorov for the murder of Tair Rada, it highlights how these communities serve as platforms for “professional amateurs” and demonstrates their similarities and differences from participants in the formal legal arena.MethodsThe study employs a netnographic approach to analyze seven years of social media activity across 15 Facebook groups comprising over 300,000 members. Data collection included participant observation, interviews with 25 group administrators, and thematic content analysis of posts and interactions. This methodological triangulation provides a comprehensive understanding of the discourse and dynamics within these activist communities.ResultsSix categories of experts were identified in the online discourse: 1. Court-admissible experts, including People directly connected to the case, people who are knowledgeable about the involved parties and the surrounding area, expert witnesses who are professionals testifying based on their field-specific expertise, and circumstantial witnesses who have experienced relevant events firsthand. 2. Non-court-admissible experts, including people with deep, self-taught expertise and people relying on nonrational sources, such as supernatural insights. The findings highlight the unique character of online activism as a dialogic space where conventional and unconventional forms of expertise coexist, contributing to public narratives around justice.DiscussionThe study offers a novel conceptualization of online communities as platforms for expert-driven discourse. It underscores the importance of “pro-am” expertise and symbolic capital in shaping public understanding of contentious issues. While focused on a specific legal case, the study provides broader insights into the dynamics of expertise in online activism, emphasizing the duality of court-admissible and non-court-admissible expertise. Future research should explore these dynamics across varied contexts to further understand the role of online communities in social discourse and activism.

Published: December 2024

IntroductionUndiagnosed atrial fibrillation (AF) is a potential underlying cause of cryptogenic stroke. Prolonged screening for AF using a photoplethysmography (PPG) smartwatch might offer a solution for detecting AF in patients with cryptogenic stroke. In this study, we aim to investigate this strategy by comparing AF detection rates using a PPG-smartwatch and 48 h Holter monitor.MethodsFrom December 2019, patients with cryptogenic stroke were included to undergo 28 days of semi-continuous AF monitoring using a Fitbit smartwatch with a PPG-based FibriCheck algorithm, with simultaneous Holter monitoring during the first 48 h. From April 2021, a detailed screening log was installed to characterize potential study participants.ResultsAfter logged screening of 1,312 patients, enrollment was prematurely halted due to slower-than-expected inclusion rates. 40.8% of the screened patients had cryptogenic stroke, of which 92.5% were non-eligible for inclusion due to logistical, technological, and study-related challenges. Of the 43 patients enrolled, 37 completed PPG monitoring using a smartwatch. 43% of patients had PPG-detected AF in the 28 days after cryptogenic stroke. During the first 48 h, PPG-based screening detected AF in 2 patients, whereas no AF was detected using concurrent Holter monitoring.ConclusionThe PPG-smartwatch detected AF in 43% of the participants after cryptogenic stroke. However, discrepancies with concurrent Holter monitoring raise major concerns about the accuracy of the detected PPG-based AF. Moreover, the feasibility of a PPG-based screening strategy is limited due to logistical and technological challenges, partly inherent to cryptogenic stroke patients.

Published: December 2024

IntroductionThis study aimed to examine the relationship between the relative opening of the ICA (RO-ICA) and the structure of the ciliary cleft (CC) using Ultrasound Biomicroscopy (UBM).Materials and methodsClinical data from 31 eyes of 17 dogs at the Veterinary Teaching Hospital of Chungbuk National University, Korea, were analyzed. RO-ICA was categorized as “Slightly Narrow”, “Narrow”, “Open”, and “Wide Open”, with eyes further grouped into “Narrow” (including Slightly Narrow and Narrow) and “Open” (including Open and Wide Open) for analysis. Statistical methods, including linear regression and average comparisons between groups, were employed to explore correlations between RO-ICA and parameters such as ICA, CC width (CCW), CC length (CCL), and CC area (CCA).ResultsThe distribution showed “Narrow” (3 eyes, 9.7%), “Slightly Narrow” (13 eyes, 41.9%), and “Open” (14 eyes, 45.2%) as the predominant categories. In the Open group, CCL and CCA were significantly larger compared to the Narrow group. A positive correlation was observed between RO-ICA and CCL, and CCA across all groups. Notably, in the Narrow group, RO-ICA demonstrated a particularly significant positive correlation with all assessed parameters, including ICA, CCW, CCL, and CCA. However, no significant correlation was observed between RO-ICA and the assessed parameters in the Open group. In conclusion, while a smaller RO-ICA generally correlates with a smaller CC, a larger RO-ICA does not guarantee a larger CC.ConclusionAdditional UBM examinations are recommended for comprehensive evaluations, particularly in cases where gonioscopy indicates an open iridocorneal angle.

Пахидермопериоститът представлява първична форма на хипертрофична остеоартропатия. Антисинтетазният синдром е автоимунна болест, която се характеризира се с автоантитела срещу една от многото аминоацил транспортна РНК синтетази и развитие на интерстициална белодробна болест, неерозивен артрит, миозит, феномен на Рейно, необясним фебрилитет и „ръце на механик”. Представяме пациентка на 36 г., която постъпва в ревматологична клиниката от дифузни ставни болки и периодична поява на оток в коленните стави, дифузни миалгии, побеляване и посиняване на пръстите на ръцете и стъпалата с фебрилитет във вечерните часове от около 1 г. Впоследствие при болната се появи фоточувствителен еритем по лицето. Проведената ангиопулмография дава данни за белодробна хипертония от венозен тип и начална спленопортална хипертония. При прегледа впечатление прави синдром на Рейно, пръсти тип „барабанна палка“ и нокти тип „часовниково стъкло“. Направените изследвания демонстрират нормални острофазови показатели и мускулносвързани ензими, повишени ANA и многократно завишени anti-PL-7 и anti-Ro-52. От High Resolution Computed Tomography на бели дробове не се установяват патологични промени. Кожната биопсия показа отлагане на IgM по дермоепидермалната граница. Функционално изследване на дишането показа изолиран спад на TLCO, което би могло да се обясни с пулмоналната хипертония. Приехме, че при пациентката са налични Пахидермопериостит и Антисинтетазен синдром. Започна се лечение с Кортикостероиди, Плакенил и Азатиоприн с добър ефект.

A fibromialgia é uma condição crônica caracterizada por dor musculoesquelética difusa, acompanhada de sintomas como fadiga, distúrbios do sono e problemas cognitivos, muitas vezes chamados de "névoa cerebral". Estima-se que afete cerca de 2-4% da população mundial, com prevalência maior entre mulheres na faixa etária de 30 a 60 anos. Embora a fibromialgia não cause danos visíveis nos tecidos, ela representa uma carga significativa tanto para os pacientes quanto para o sistema de saúde, pois seus sintomas frequentemente resultam em incapacidade funcional e deterioração da qualidade de vida. A pesquisa sobre o uso do canabidiol para o manejo da fibromialgia é de grande importância, considerando a necessidade de tratamentos mais eficazes e com menos efeitos colaterais para essa condição crônica debilitante. Embora os tratamentos convencionais, como antidepressivos e anticonvulsivantes, tenham mostrado algum sucesso, muitos pacientes continuam a sofrer com sintomas incapacitantes, além dos efeitos adversos dos medicamentos. Trata-se de uma revisão sistemática da literatura, a qual investigou sobre o uso de canabidiol para o manejo da fibromialgia, pela coleta de dados nas plataformas PubMed, LILACS, Periódicos CAPES, EMBASE e Scielo. Assim, a utilização de canabinoides no tratamento da fibromialgia tem demonstrado ser uma abordagem terapêutica promissora, embora os dados disponíveis ainda sejam limitados e necessitem de maior robustez para confirmar seus benefícios e segurança a longo prazo. Os estudos analisados evidenciam que tanto o Δ-9-tetrahidrocanabinol (THC) quanto o canabidiol (CBD) podem ter efeitos positivos no alívio da dor, melhora do sono e redução de outros sintomas associados à fibromialgia, como fadiga e depressão, com alguns resultados indicando melhorias significativas na qualidade de vida dos pacientes.

Prognose nicht-struktureller Schäden im Rahmen von Simulations-Tools: Anforderungen an die Datenaufbereitung
Authors:   Jochen Schwarz,   Christian Kaufmann,   Tobias Langhammer,   Holger Maiwald
Published: December 2024

Bei den in deutschen Erdbebengebieten zu erwartenden Intensitäten dominieren nicht-strukturelle Schäden an Schornsteinen, Giebelwänden und ähnliches das Schadensbild. Ihre Prognose ist derzeit im Rahmen der verfügbaren Simulations-Tools ausgeblendet, zumal bereits der Vertrauenswürdigkeit der Ergebnisse für die Gebäude Grenzen gesetzt sind.

Im Beitrag wird untersucht, welche Aufgaben bestehen, um Szenarien zu den nicht-strukturellen Schäden durchzuführen. Den Einstieg bieten die Klassifikation der Schadensgrade von Mauerwerksbauten in der EMS-98 sowie die charakteristischen Indikatoren, die die Schäden an den Schornsteinen in die Definition aufnehmen.

Es wird eine Systematisierung der während der letzten starken Erdbeben in Deutschland beobachteten Schäden vorgenommen. Mit dem Zuschnitt auf fünf Schadensgrade wird die Aufnahme in vorhandene Simulations-Tools erleichtert. In Ergänzung zu der (mit der EMS-98) für die Bauwerke gewährleisteten Zuordnung von Verletzbarkeitsklassen wird ein Konzept zur Verletzbarkeitsbewertung der hauptsächlich geschädigten Schornsteine vorgeschlagen, das mit dem eingeführten Klassifikationsschema der Schadengrade als separate Bearbeitungslinie in simulative Verfahren der Schadensprognose eingeführt werden kann.

Eingehend wird diskutiert, wie die verfügbaren Geoinformationen mit der Stufe LoD2 übernommen werden können beziehungsweise welche Schritte der Aufbereitung zur Visualisierung der Ergebnisse (für die unterschiedlichen Substrukturen von Keller, Geschossen, Dach und zugehörigen Sekundärsystemen) zu unternehmen sind. Hier wird ein erster Zwischenstand präsentiert und am Beispiel des Erdbebens von Nieder-Beerbach vom 14. Mai. 2014 zur Anwendung gebracht. Dabei kann auf die Schadensanalyse und Bestandserhebung der Autoren Bezug genommen werden.
Extracapsular Prostate Brachytherapy Using Iodine-125 for Intermediate and Selected High-Risk Prostate Cancer: Technical Notes
Authors: Goy Barry W. 
Published: December 2024

Abstract

Introduction:
Our aim is to describe extracapsular prostate brachytherapy (ECPB) techniques using low-dose-rate (LDR) for patients with intermediate-risk prostate cancer (IRPC) and selected high-risk prostate cancer (HRPC).

Materials and Methods:
Using stranded iodine-125 seeds, dose can be extended to the capsule and seminal vesicles (SVs). Intraoperative use of fluoroscopy with a cystogram can increase the extracapsular dose at the base and proximal SV compared with using ultrasound alone, with a seed source at the tip of each needle to push the dose cephalad. Visualization of the prostate base can be improved with a urinary catheter, with additional seeds placed posterior to the catheter balloon, along with additional stranded sources placed into the SV. For apical disease, a needle tip can be placed at the apex of the prostate under ultrasound guidance, and a fluoroscopic image can be referenced during the case, to ensure seed placement below the prostate apex. A peripheral loading technique is applied so that there is at least 3 mm coverage beyond the prostate radially, while additional seeds are inserted into areas of gross disease.

Results:
Our prior published experience of IRPC and selected HRPC showed excellent freedom from biochemical failure with 10-year follow-up. Our ECPB approach requires the use of more seeds (P < .0001), compared with a standard prostate brachytherapy approach, while requiring the use of fluoroscopy in addition to ultrasound.

Conclusion:
LDR prostate brachytherapy using iodine-125 alone with extracapsular techniques is a reasonable treatment option for IRPC and selected HRPC, but unfortunately is becoming a lost art.
