Cardiovascular diseases are the leading cause of death globally, making the development of non-invasive and simple-to-use tools that bring insights into the state of the cardiovascular system of utmost importance. We investigated the possibility of using peripheral pulse wave recordings to estimate stroke volume (SV) and subject-specific parameters describing the selected properties of the cardiovascular system. Peripheral pressure waveforms were recorded in the radial artery using applanation tonometry (SphygmoCor) in 35 hemodialysis (HD) patients and 14 healthy subjects...

Fire and smoke detection is crucial for the safe mining of coal energy, but previous fire-smoke detection models did not strike a perfect balance between complexity and accuracy, which makes it difficult to deploy efficient fire-smoke detection in coal mines with limited computational resources. Therefore, we improve the current advanced object detection model YOLOv8s based on two core ideas: (1) we reduce the model computational complexity and ensure real-time detection by applying faster convolutions to the backbone and neck parts; (2) to strengthen the model's detection accuracy, we integrate attention mechanisms into both the backbone and head components...

BACKGROUND: Cognitive function, including moral decision-making abilities, can be impaired by sleep loss. Blue-enriched light interventions have been shown to ameliorate cognitive impairment during night work. This study investigated whether the quality of moral decision-making during simulated night work differed for night work in blue-enriched white light, compared to warm white light. METHODS: Using a counterbalanced crossover design, three consecutive night shifts were performed in blue-enriched white light (7000 K) and warm white light (2500 K) provided by ceiling-mounted LED luminaires (photopic illuminance: ∼200 lx)...

The primary purpose of this single-arm mixed-methods pilot trial was to examine the feasibility, acceptability, and preliminary effects of a text message-based version of Caring Contacts, Caring Contacts texts (CC-t), among veterans recently separated from military service. Twenty-four veterans ( M age = 32.92, SD = 8.16; 75% male; 50% Black; 91.7% non-Hispanic/Latinx) were recruited through the Department of Veterans Affairs (VA) and enrolled in CC-t, which involved approximately five text messages sent by the study team expressing care and concern over the course of 3 months...

A persistent finding in the autobiographical memory (AM) literature is that older adults report more nonepisodic (or generalized/semantic) information than young adults. Since studies are usually focused on memory for episodic (or specific) autobiographical events, the reason for the age difference in nonepisodic AM remains understudied. This experiment investigated whether the higher rate of nonepisodic AM in older adults reflects (a) a difference incommunicative preferences or (b) cognitive decline, by way of either an inhibition deficit or as a means of compensating for a deficit in episodic AM...

Issue:  A significant component of health professions education is focussed on students' exposure to the social determinants of health and the challenges that patients within the health care system face. An appropriate way to provide such exposure is through distributed clinical training. This usually entails students training in smaller groups along the continuum of care, away from tertiary academic hospitals. This also means students are away from their existing academic and social support systems. It is evident that knowledge and clinical skills alone are not sufficient to prepare students, they also need to be taught to critically reflect on how their own values and attitudes traverse their knowledge and skills to influence their practice as healthcare professionals...

INTRODUCTION: Suicide is a leading cause of death, making suicide prevention a major public health priority. Increasing understanding of factors influencing suicidal behavior is paramount. Previous research has implicated psychological closeness, characterized by perceptions of how close/distant or attached/detached one feels to a particular object, as a cognitive factor that influences suicidal behavior. However, a better understanding of how psychological closeness to suicide methods is conceptualized by relevant populations is needed to improve its assessment and understand how it may confer risk for suicide...

OBJECTIVE: To assess the possibilities of fluorescent detection system in qualitative and quantitative assessment of bowel perfusion in colorectal resections. MATERIAL AND METHODS: From May to August 2023, a single-center pilot cross-sectional unblinded study with inclusion of 18 patients with colon cancer (of left-sided - 12, of right-sided - 6, mean age - 72.9 years, m/w - 61/39%) was conducted. All patients underwent laparoscopic colorectal resections with extracorporeal stage of bowel transection...

BACKGROUND: The economic burden of chronic psychotic disorders is substantial. However, few studies have employed an incidence based approach to estimate the economic burden of chronic psychotic disorders. Furthermore, the existing work has mainly used models populated with data obtained from published literature, making several assumptions to estimate incidence-based costs. AIMS OF THE STUDY: The objective of this study was to estimate the direct cumulative mean health care costs of chronic psychotic disorders, using an incidence-based, cost-of-illness approach and real-world data from a single-payer health care system...

BACKGROUND: Suicidal thoughts and behaviours (STB) represent a persistent and serious public health problem, and suicide is among the leading causes of death worldwide. We focus on predictors of transition rates and time courses through the STB spectrum among psychiatric emergency room (PER) patients. AIMS: We aimed to investigate (a) whether currently suicidal patients had prior referrals to the PER, (b) for which reason they were previously referred to the PER and (c) the timing of this referral...

Distantly related mammals (e.g. jerboa, tarsiers, kangaroos) have convergently evolved elongated hindlimbs relative to body size. Limb elongation is hypothesized to make these species more effective jumpers by increasing their kinetic energy output (through greater forces or acceleration distances), thereby increasing take-off velocity and jump distance. This hypothesis, however, has rarely been tested at the population level, where natural selection operates. We examined the relationship between limb length, muscular traits, and dynamics using Longshanks mice, which were selectively bred over 22 generations for longer tibiae...

Given the aging population, finding solutions to retain optimal cognitive capacity is a research priority. The potential of physical activity to reduce the risk of cognitive decline and to enhance cognitive functioning is established. Combining physical with cognitive activity has been put forward as a potentially even more effective way to promote healthy cognitive aging. Most studies on combined interventions have however been conducted in laboratory settings. This paper reports on a two-phased pilot study evaluating the acceptability and feasibility of a newly developed real-life cognitively enriched walking program for adults aged 65+ years...

OBJECTIVE: To present an alternative technique called pseudo-flap for reconstructing long ureteral defects as an alternative to Boari flap. Despite being used for more than 70 years by urologists for tension-free reconstruction of distal and mid-ureteral defects, the Boari flap exhibits high complication rates, with an average of 27% (range 5.5%-30.4%). These complications arise from compromised blood supply, attributed to incisions made on all three sides of the flap and dependence on the flap base as the sole source of blood supply...

OBJECTIVES: Kerala was the first state to implement a community-based, sustainable primary palliative care (PC) home care (HC) model. Beneficiary satisfaction, an important indicator to assess the quality of service provision with the HC program, has not been assessed since the programme was launched 14 years ago. This study tried to assess the satisfaction of beneficiaries receiving primary PC services through the Kerala State PC programme and the factors associated with the same. MATERIALS AND METHODS: The cross-sectional survey was conducted among 450 patients registered under the Kerala State Primary PC Programme...

INTRODUCTION: Wearables are potentially valuable tools for understanding mobility behavior in individuals with neurological disorders and how it changes depending on health status, such as after rehabilitation. However, the accurate detection of gait events, which are crucial for the evaluation of gait performance and quality, is challenging due to highly individual-specific patterns that also vary greatly in movement and speed, especially after stroke. Therefore, the purpose of this study was to assess the accuracy, concurrent validity, and test-retest reliability of a commercially available insole system in the detection of gait events and the calculation of stance duration in individuals with chronic stroke...

BACKGROUND: Malaria remains one the leading communicable causes of death. Approximately half of the world's population is considered at risk of infection, predominantly in African and South Asian countries. Although malaria is preventable, heterogeneity in sociodemographic and environmental risk factors over time and across diverse geographical and climatological regions make outbreak prediction challenging. Data-driven approaches accounting for spatiotemporal variability could offer potential for location-specific early warning tools for malaria...

BACKGROUND: Melanocytic nevi are frequently observed in the pediatric population. While newly acquired nevi can appear during childhood, congenital nevi can continue to grow and clinically change, making patient caregivers concerned. Reflectance confocal microscopy (RCM) in vivo is a noninvasive tool that might enhance the diagnostic accuracy of dermoscopy, reducing the rate of unnecessary surgical procedures. This study aimed to assess the utility of RCM in increasing the diagnostic accuracy of pediatric melanocytic nevi that show pigmentation changes or grow rapidly...

Diffusing diffusivity models, polymers in the grand canonical ensemble and polydisperse, and continuous-time random walks all exhibit stages of non-Gaussian diffusion. Is non-Gaussian targeting more efficient than Gaussian? We address this question, central to, e.g., diffusion-limited reactions and some biological processes, through a general approach that makes use of Jensen's inequality and that encompasses all these systems. In terms of customary mean first-passage time, we show that Gaussian searches are more effective than non-Gaussian ones...

BACKGROUND: In this paper, we look at how to design and build a system to find tumors using 2 Convolutional Neural Network (CNN) models. With the help of digital image processing and deep Learning, we can make a system that automatically diagnoses and finds different diseases and abnormalities. The tumor detection system may include image enhancement, segmentation, data enhancement, feature extraction, and classification. These options are set up so that the CNN model can give the best results...
