OBJECTIVE: This study evaluated the accuracy and precision of digital models acquisition using a home-built, low-cost scanning system based on the structured light method. METHODS: a plaster model (PM) was scanned using the experimental device (SL) and a dental desktop scanner (DS). The teeth dimensions of PM and SL models were measured in triplicate, with a caliper and digitally, respectively. The agreement of the measurements of each model was evaluated using the intraclass correlation coefficient, and the validity between the different measurement techniques was assessed using the Bland-Altman analysis...

The robotic platform matches or surpasses laparoscopic surgery in postoperative results. However, limited date and slow adoption are noticed in the middle east. We aimed to report outcomes of robotic and laparoscopic colorectal surgery performed by fellowship-trained robotic colorectal surgeons and compare it to larger more experienced centers. Retrospective review of prospectively collected data between 2021 and 2023 of 107 patients who had robotic-assisted or laparoscopic-assisted colorectal surgery was included in the study...

OBJECTIVE: This article presents the National Healthcare Safety Network (NHSN)'s approach to automation for public health surveillance using digital quality measures (dQMs) via an open-source tool (NHSNLink) and piloting of this approach using real-world data in a newly established collaborative program (NHSNCoLab). The approach leverages Health Level Seven Fast Healthcare Interoperability Resources (FHIR) application programming interfaces to improve data collection and reporting for public health and patient safety beginning with common, clinically significant, and preventable patient harms, such as medication-related hypoglycemia, healthcare facility-onset Clostridioides difficile infection, and healthcare-associated venous thromboembolism...

Background Youth vaping is an epidemic, being more prevalent than any other tobacco use. To inform cessation interventions, we explored what adolescents perceive to be their reasons for quitting and strategies to help in their quit efforts. Method Semi-structured interviews were conducted with a convenience sample of 11 adolescents reporting vaping in the past 90 days and recruited from a high school in Massachusetts. Interviews were transcribed, and dual coded. Inductive thematic analysis was employed and thematic summaries were prepared...

Bacterial biofilms form when bacteria attach to surfaces and generate an extracellular matrix that embeds and stabilizes a growing community. Detailed visualization and quantitative analysis of biofilm architecture by optical microscopy are limited by the law of diffraction. Expansion Microscopy (ExM) is a novel Super-Resolution technique where specimens are physically enlarged by a factor of ~4, prior to observation by conventional fluorescence microscopy. ExM requires homogenization of rigid constituents of biological components by enzymatic digestion...

Blackberry production is increasing in the southeastern U.S. with the availability of new cultivars. In addition to high production costs, growers are challenged by virus diseases. Blackberry yellow vein disease (BVYD) significantly limits blackberry production. BYVD is associated with the crinivirus blackberry yellow vein-associated virus (BYVaV) in mixed infections with other viruses. The specific disease etiology and ecological factors underlying BYVD are not well understood and rely on the effective diagnosis of several viruses involved in the complex...

The use of strategies to reduce blood loss and transfusions is essential in the treatment of surgical patients, including in complex cardiac surgeries and those that use cardiopulmonary bypass. Antifibrinolytics, such as epsilon-aminocaproic acid (EACA) and tranexamic acid (TXA), are widely used in these procedures, as well as in other types of surgeries. These medicines are included in the World Health Organization (WHO) list of 'essential medicines'. Scientific evidence demonstrates the effectiveness of EACA in reducing bleeding and the need for transfusions in heart surgery...

BACKGROUND: Frequent anti-vascular endothelial growth factor A (VEGF-A) injections reduce the risk of rapid and severe vision loss in patients with neovascular age-related macular degeneration (nAMD); however, due to undertreatment, many patients lose vision over time. New treatments that provide sustained suppression of VEGF-A are needed. RGX-314 (currently known as ABBV-RGX-314) is an adeno-associated virus serotype 8 vector that expresses an anti-VEGF-A antigen-binding fragment, which provides potential for continuous VEGF-A suppression after a single subretinal injection...

The management of major bleeding is a critical aspect of modern healthcare and it is imperative to emphasize the importance of applying Patient Blood Management (PBM) principles. Although transfusion support remains a vital component of bleeding control, treating severe bleeding goes beyond simply replacing lost blood. A more comprehensive, multidisciplinary approach is essential to optimize patient outcomes and minimize the risks associated with excessive transfusions.

Patient Blood Management (PBM) is a holistic approach to managing blood as a resource of each patient; it is a multimodal strategy that is implemented using a set of techniques that can be applied in individual cases. In fact, the overall result of the implementation of PBM cannot be fully appreciated or explained by simply summing up the effects of the individual strategies and techniques used, since they can only produce the expected ideal result if combined. Implementing a PBM program in healthcare offers several benefits including improved patient safety, better outcomes, cost savings, conservation of resources, evidence-based practice, transfusion alternatives, improved quality of care, compliance with accreditation standards, patient-centered care, and professional education and training...

Recent movements like #MeToo and #TimesUp have surfaced and challenged ideas about masculinity in popular conversations. In particular, these ideas have centered around "toxic masculinity"-a version of masculinity that reflects stereotyped, dated, and even dangerous expectations for manhood. This notion of masculinity can be reinforced in a number of ways, especially through pop culture, where it runs the risk of becoming commonly accepted or normalized. This study evaluates the narratives of masculinity in three different novels that are marketed toward high school-aged students in the United States: Lord of the Flies ; Gabi, A Girl in Pieces ; and Aristotle and Dante Discover the Secrets of the Universe ...

Conventional methods for pathogen detection in water rely on time-consuming enrichment steps followed by biochemical identification strategies, which require assay times ranging from 24 hours to a week. However, in recent years, significant efforts have been made to develop biosensing technologies enabling rapid and close-to-real-time detection of waterborne pathogens. In previous studies, we developed a plastic optical fiber (POF) immunosensor using an optoelectronic configuration consisting of a U-Shape probe connected to an LED and a photodetector...

Tara gum, a natural biopolymer extracted from Caesalpinia spinosa seeds, was investigated in this study. Wall materials were produced using spray drying, forced convection, and vacuum oven drying. In addition, a commercial sample obtained through mechanical methods and direct milling was used as a reference. The gums exhibited low moisture content (8.63% to 12.55%), water activity (0.37 to 0.41), bulk density (0.43 to 0.76 g/mL), and hygroscopicity (10.51% to 11.42%). This allows adequate physical and microbiological stability during storage...

Background: The aim of this study was to investigate whether high body mass index (BMI) increases the risk of recurrence and correlates with higher glucose uptake in recurrent lesions in post-menopausal female patients with breast cancer. Methods: A hospital database was searched to retrieve breast cancer patients who had undergone an [18 F]FDG PET/CT scan before neoadjuvant chemotherapy and curative-intent surgery. BMI was calculated at the baseline [18 F]FDG PET/CT scan. There was a median follow-up of 5 years after the baseline PET/CT scan to identify recurrence in the breast (T_rec); lymph nodes (N_rec); and distant locations (M_rec)...

Schizophrenia (SZ) is a widespread psychiatric disorder that is traditionally characterized by positive and negative symptoms. However, recent focus has shifted to cognitive deficits as a crucial aspect. The cerebellum, conventionally tied to motor coordination, is now recognized as pivotal in the pathophysiology of SZ cognitive impairments. Proposed disruptions in the cortico-cerebellar-thalamic-cortico circuit contribute to these deficits. Despite evidence of cerebellar abnormalities, within-cerebellum functional connectivity is often overlooked...

Although lung cancer (LC) is one of the most common and lethal tumors, only 15% of patients are diagnosed at an early stage. Smoking is still responsible for more than 85% of cases. Lung cancer screening (LCS) with low-dose CT (LDCT) reduces LC-related mortality by 20%, and that reduction reaches 38% when LCS by LDCT is combined with smoking cessation. In the last decade, a number of countries have adopted population-based LCS as a public health recommendation. Albeit still incipient, discussion on this topic in Brazil is becoming increasingly broad and necessary...

BACKGROUND: The impact of coronavirus disease 2019 (COVID-19) on postoperative recovery from oncology surgeries should be understood for the clinical decision-making. Therefore, this study was designed to evaluate the postoperative cumulative 28-day mortality and the morbidity of surgical oncology patients during the COVID-19 pandemic. METHODS: This retrospective cohort study included patients consecutively admitted to intensive care units (ICU) of three centres for postoperative care of oncologic surgeries between March to June 2019 (first phase) and March to June 2020 (second phase)...

Cancer stem cells (CSCs) are a niche of highly tumorigenic cells featuring self-renewal, activation of pluripotency genes, multidrug resistance, and ability to cause cancer relapse. Seven HDACi (1-7), showing either hydroxamate or 2'-aminoanilide function, were tested in colorectal cancer (CRC) and glioblastoma multiforme (GBM) CSCs to determine their effects on cell proliferation, H3 acetylation levels and in-cell HDAC activity. Two uracil-based hydroxamates, 5 and 6, which differ in substitution at C5 and C6 positions of the pyrimidine ring, exhibited the greatest cytotoxicity in GBM (5) and CRC (6) CSCs, followed by the pyridine-hydroxamate 2, with 2- to 6-fold higher potency than the positive control SAHA...

PURPOSE: This study evaluated the velocity-selective (VS) MRA with different VS labeling modules, including double refocused hyperbolic tangent, eight-segment B1-insensitive rotation, delay alternating with nutation for tailored excitation, Fourier transform-based VS saturation, and Fourier transform-based inversion. METHODS: These five VS labeling modules were evaluated first through Bloch simulations, and then using VSMRA directly on various cerebral arteries of healthy subjects...

Managing anemia before surgery is extremely important as it is a clinical condition that can significantly increase surgical risk and affect patient outcomes. Anemia is characterized by a reduction in the number of red blood cells or hemoglobin levels leading to a lower oxygen-carrying capacity of the blood. Proper treatment requires a multifaceted approach to ensure patients are in the best possible condition for surgery and to minimize potential complications. The challenge is recognizing anemia early and implementing a timely intervention to correct it...
