T his study examines the social-digital behaviors of online communities through the experience of building an online mandala. The article provides historical background to ancient practice of sand painting, or mandala, as a social phenomenon through its evolution to online application and participation via the social media app, Reddit, and their r/place digital mandala creation experiences hosted in 2017 and again in 2022. The methodology employed for the study was agile ethnography. Data analysis affirmed that Reddit remains a nexus for individuals to communicate and experience authentic human connection through digital format. Further, data analysis revealed interesting points regarding the communication initiation-response phenomenon with comparison of similarity and difference behaviors between the 2017 and 2022 experiences, evolution of the community experience in the construction of the digital mandalas by r/place subgroups, and the emergence of collaborative and chaotic evil, good and neutral participants, and groups. The study also provides ideas for future socio-digital research. [ABSTRACT FROM AUTHOR]

Ketamine is the prototypal rapid-acting antidepressant (RAAD) for TRD with approved indication for esketamine-nasal spray (ESK-NS). Distinctly, arketamine (R-KET) demonstrates enhanced antidepressant effects and neuroplasticity changes compared to esketamine, with fewer dissociative side effects and abuse potential. This study focuses on R-ketamine's therapeutic implications, safety, and tolerability in TRD treatment. We report on a year-long follow-up of three TRD patients post-single IV R-KET administration. The study, conducted under the clinical trial PCN-101 (NCT05414422), observed these subjects for healthcare resource utilization and social support system impact. Participants, adults diagnosed with recurrent major depressive disorder without psychotic features, were observed in a year-long follow-up period for safety. Case analyses revealed significant symptom reduction and improved social and vocational functioning, with reduced sick leaves and hospitalizations post-treatment. However, one case developed a substance use disorder, underscoring the need for vigilant monitoring. The study highlights R-KET's transformative potential in managing depression, indicating a shift in TRD treatment strategies towards early, aggressive interventions. Despite promising findings, the study faces limitations due to its small sample size, lack of randomization, and potential observational design biases. The results, while aligning with existing ketamine research, require cautious interpretation and warrant further investigation with larger, more robust studies. This exploration of R-KET's role in home-based TRD treatment opens avenues for future research, particularly focusing on its long-term effectiveness and safety in diverse patient populations. This study is registered in clinicaltrials.gov: NCT06232291. [ABSTRACT FROM AUTHOR]

• We describe the surfaces of radiovisiograms in the healing process after bone loss using multifractal texture analysis. • Radiovisiogams are an alternative technique for assessing the structure of bone remodeling. • The studied group consists of 19 patients: Group A – images directly after the procedure, Group B – images after 12 months. • The multifractal spectrum width increases significantly one year after the operation. • The multifractal analysis of the healing process after bone loss quantify a lasting clinical result. In this work we have proposed to use multifractal analysis to evaluate the effectiveness of the healing process in postresectal and postcystal bone loss using the guided bone regeneration (GBR). The material of the study consists of 19 radiographic images obtained from patients (13 females and 6 males), observed within 1-year-long period, who had undergone bone augmentation with xenogenic material. Using radiographic images (RVG) made with digital radiography set Kodak RVG 6100 on the day of the procedure (Group A) and 12 months later (Group B), the degree of reconstruction of intraosseous defects were compared. A visual subjective evaluation of the healing process based on RVG images may not be sufficient. For this purpose, modern computer image analysis methods can be used. Pre-processing of radiographic images consisted of separating areas of interest (ROI) and binarization. The resulting images were analyzed using multifractals. The properties of biological structures cannot be sufficiently described in the Euclidean space, but they can be characterized by a parameter called the fractal dimension. Significant increase (p < 0.0001) of multifractal features were found in patients from group B. Individual parameters may characterize bone structure, which had undergone bone augmentation with xenogenic material. Finally, we showed that the properly selected multifractal quantificators obtained for those images could be used to assign those images to the appropriate group. The proposed analysis based on RVG images could help to evaluate the healing process after bone loss. The analysis and interpretation of the healing process after bone loss using monofractal and multifractal analysis as a multi-steps process quantify a stable (good) clinical result.

The available studies on cerebrovascular reactivity and cerebral oxygenation in obstructive sleep apnoea (OSA) patients brought conflicting results, yet the overall evidence suggests that resting state cerebral perfusion is diminished in these patients. Interestingly, in a group of healthy professional breath-hold divers who are exercising very long apnoeas - episodes corresponding to the ones observed in patients with OSA - demonstrated that cerebral oxygenation may remain stable at the expense of extreme sympathetic nervous system (SNS) activation. In the present review we address several mechanisms that could potentially explain these discrepancies. We focus in depth on mechanisms of central SNS reinforcement in OSA including dysfunctional baroreflex response, and inflammatory processes within the brain centres controlling the cardiovascular system. Additionally, novel insights into physiology of cerebral blood flow regulation are proposed, including the role of short-term blood pressure changes, heart rate fluctuations and baroreflex alterations. Finally, a potential role of increased blood flow pulsatility in cerebrospinal fluid circulation changes and its influence on SNS drive is highlighted. The presented review provides insights into how sympathetic nervous system reinforcement in OSA promotes maladaptive mechanisms that could alter cerebral perfusion regulation, and result in functional and structural cerebral changes.

The article discusses the Anglo-Saxons' understanding of creation. It compares the Biblical Genesis 1, which it calls an authoritative Christian narrative, with Anglo-Saxon texts in Latin and Old English. It notes that the Church Fathers did not agree on the accounts of creation. It examines texts including Aelfric's "Exameron Anglice," the text "Metre 20," "Caedmon's Hymn," and the "Song of Creation " from the epic poem "Beowulf" as sources.

The purpose of this report is to describe an endomechanical product evaluation and selection program in open surgical procedures as well as laparoscopic surgery designed by hospital representatives of Consorta, Inc. (Rolling Meadows, Illinois), a leading healthcare resource management and group purchasing organization, and Auto Suture/United States Surgical, (a division of Tyco Healthcare Group LP, Norwalk, Connecticut). In this evaluation program, twenty-three facilities of the six Consorta shareholder partners hospitals enrolled surgeons to participate in this nonexperimental observational study of the clinical performance of endomechanical products. Performance characteristics of the endomechanical products produced by Auto Suture that were evaluated in 1145 surgical procedures included clinically acceptable ratings, clinically not acceptable ratings, as well as superior ratings in 2988 product evaluations. In this endomechanical product evaluation, the surgeons found that the endomechanical products were clinically acceptable in 97.7% of the evaluations. In these endomechanical products that were judged to be clinically acceptable, the surgeons gave a superior rating to 20% of the products. It is important to emphasize that the clinically acceptable performance of laparoscopic products (98.1%) was very similar to that of endomechanical performance during open surgery (96.9%). Similarly, a superior rating of laparoscopic products that were judged to be clinically acceptable (22%) was comparable to that of the superior rating for endomechanical products that were considered to be clinically acceptable during open surgery (16%). The general surgeons who performed the majority (64.3%) of the product evaluations for the endomechanical products found an extremely high clinical acceptable rating in 98.2% of the evaluations. The obstetricians and gynecologists who performed the next highest number of procedures, 427 (14.3%), had a clinically... [ABSTRACT FROM AUTHOR]

The purpose of this report is to describe an expanded suture and needle clinical evaluation program jointly designed by hospital representatives of Consorta, Inc. (Rolling Meadows, Illinois), a leading healthcare resource management and group purchasing organization, and United States Surgical/Davis & Geck Sutures (Division of United States Surgical, Norwalk, Connecticut). In this expanded evaluation program, 42 Consorta shareholder hospitals enrolled 1913 surgeons to participate in Phase II of this non-experimental observational study of the clinical performance of surgical needles and sutures. Performance characteristics of the sutures and needles produced by USS/DG that were evaluated in 25,545 surgical procedures included packaging/ease of opening, needle strength and sharpness, tissue drag, knot security, tensile strength, clinically acceptable determinations, and clinically unacceptable determinations. In these 30-day studies, the surgeons found that the needles and sutures were clinically acceptable in 98.1% of the evaluations. The general, cardiothoracic, and orthopedic surgeons who performed 61.2% of the product evaluations reported that the suture and needle products were clinically acceptable in 98.2% of the evaluations. Nearly hale (49.2%) of the evaluations involved the POLYSORB* braided synthetic sutures that received a clinically acceptable rating in 98.2% of the evaluation. The silk suture (SOFSILK*), followed by the monofilament nylon suture (MONOSOF*), were the next most frequently used sutures. The SOFSILK* was found to be clinically acceptable in 99.2% of the evaluations, while MONOSOF* was noted to be clinically acceptable in 98.7% of the evaluations. Surgical needles made by USS/DG Sutures also had a high rating of clinical acceptability (97.9%). [ABSTRACT FROM AUTHOR]
