BACKGROUND: Infra-red photocoagulation is used as an instrumental treatment for bleeding hemorrhoids. During this procedure the tissue is coagulated by infrared radiation. For treatment, mechanical pressure and radiation energy are applied simultaneously to ablate the blood supply to the hemorrhoidal mass. MATERIAL AN…

The Katz centrality of a node in a complex network is a measure of the node's importance as far as the flow of information across the network is concerned. For ensembles of locally tree-like undirected random graphs, this observable is a random variable. Its full probability distribution is of interest but difficult to…

OBJECTIVE: With its anonymity and accessibility, text-based online counseling has shown great potential in reaching people with mental health needs. One strategy adopted to meet the service gap is, that is, each counselor attending to more than one client at a time. To date, there is no reported evidence supporting its…

The experiences of medical students, residents, and faculty with a computerized literature searching system were evaluated. Third-year medical students, internal medicine and family practice residents, and full-time and voluntary faculty at one medical school had the opportunity to use a full-text and bibliographic med…

Inflicted blunt force trauma and/or repetitive acceleration-deceleration trauma in infants can cause brain injury. Yet, the exact pathophysiologic mechanism with its associated thresholds remains unclear. In this systematic review an overview of animal models for shaking trauma and their findings on tissue damage will…

OBJECTIVE: To measure the effect of free access to the scientific literature on article downloads and citations. DESIGN: Randomised controlled trial. SETTING: 11 journals published by the American Physiological Society. PARTICIPANTS: 1619 research articles and reviews. MAIN OUTCOME MEASURES: Article readership (mea…

Pleomorphic sarcoma of the tongue base is an extremely rare pathology finding. Our review of current databases returned fewer than 10 articles available free full text on this subject. We review the current state of art management guidelines for this type of tumor. Our case presented surprisingly a favorable evolution…

Meningeal carcinomatosis (MC) is a rare presentation of solid tumors, particularly breast cancer, lung cancer, and malignant melanoma. Recently, the incidence of MC has been reported to be increasing. It has a bad prognosis despite aggressive therapy. The usual clinical presentation is multifocal involvement of the neu…

Hypercomplex neural networks have proven to reduce the overall number of parameters while ensuring valuable performance by leveraging the properties of Clifford algebras. Recently, hypercomplex linear layers have been further improved by involving efficient parameterized Kronecker products. In this article, we define t…

Between April 20, 2020 and June 19, 2020 we conducted a survey of the membership of the Psychiatric Genomics Consortium (PGC) to explore the impact of COVID-19 on their research and academic careers. A total of 123 individuals responded representing academic ranks from trainee to full professor, tenured and fixed-term…

Development of journal collection in the Andrija Stampar library is presented. Research of loaned and photocopied journals was performed in order to evaluate circulation of journals in 2001. There were 1057 titles of journals in the Library, 77 were secondary journals and they were excluded from the study. 346 differen…

BACKGROUND:  Large defects of the lower lip often require free tissue coverage. Fasciocutaneous free flaps have been traditionally used, but innervated muscular free flaps may fundamentally address orbicularis oris deficiency and improve dynamic competence. This review aimed to determine if innervated muscular f…

underpin Evidence Based Medicine (EBM) by addressing precise clinical questions via comprehensive synthesis of all relevant published evidence. Authors of systematic reviews typically define a Population/Problem, Intervention, Comparator, and Outcome (acriteria) of interest, and then retrieve, appraise and synthesize r…

BACKGROUND:  In 1986, Marko Godina published his seminal work regarding the timing of free-flap reconstruction for traumatic extremity defects. Early reconstruction, compared with delayed and late reconstruction resulted in significant decreases in free-flap failure rate, post-operative infections, hospitalizati…

As a tension-free repair technique, Lichtenstein operation has gained great popularity worldwide during the last decade. Expert centres do this technique using local anaesthesia in nearly 95 % of cases. However, general anaesthesia is used in many hospitals, while regional anaesthesia is preferred in some centres. To d…

INTRODUCTION: Some low- and middle-income countries (LMICs) struggle to implement smoke-free policies. We sought to review the academic and gray literature, and propose a research agenda to improve implementation of smoke-free policies and make them more effective in LMICs. METHODS: We reviewed 10 databases for variat…

The association between impairments in swallowing safety detected via fiberoptic endoscopic evaluation of swallowing (FEES) and dysphagia complications has been evaluated in small studies that have not allowed obtaining precise estimates of the presence of such an association. The objective of this study was to evaluat…

The limitation of artificial intelligence (AI) large language models to diagnose diseases from the perspective of patient safety remains underexplored and potential challenges, such as diagnostic errors and legal challenges, need to be addressed. To demonstrate the limitations of AI, we used ChatGPT-3.5 developed by Op…

BACKGROUND: Hypernatremia is common following traumatic brain injury (TBI) and occurs from a variety of mechanisms, including hyperosmotic fluids, limitation of free water, or diabetes insipidus. The purpose of this systematic review was to assess the relationship between hypernatremia and mortality in patients with TB…

Ultrasound imaging is a vital tool for exploring in vivo the placental function which is essential to understand pathological phenomena such as preeclampsia or intrauterine growth restriction. As technology advances including ready availability of three-dimensional (3D) probes and novel software, new markers of placent…
