Ultrawideband (UWB) radar has emerged as a compelling solution for noncontact human activity recognition. This study proposes a novel framework that leverages adaptive signal decomposition and video-based deep learning to classify human motions with high accuracy using a single UWB radar. The raw radar signals were processed by empirical wavelet transform (EWT) to isolate the dominant frequency components in a data-driven manner. These components were further analyzed using the Hilbert transform to produce time–frequency spectra that capture motion-specific signatures through subtle phase variations. Instead of treating each spectrum as an isolated image, the resulting sequence was organized into a temporally coherent video, capturing spatial and temporal motion dynamics. The video data were used to train the SlowFast network—a dual-path deep learning model optimized for video-based action recognition. The proposed system achieved an average classification accuracy exceeding 99% across five representative human actions. The experimental results confirmed that the EWT–Hilbert-based preprocessing enhanced feature distinctiveness, while the SlowFast architecture enabled efficient and accurate learning of motion patterns. The proposed framework is intuitive, computationally efficient, and scalable, demonstrating strong potential for deployment in real-world scenarios such as smart healthcare, ambient-assisted living, and privacy-sensitive surveillance environments.

Hospital infection prevention is critical to patient safety, yet data on the prevalence and contributing factors of healthcare-associated infections (HAIs) in Aljouf, Saudi Arabia, are scarce. This retrospective cross-sectional study aimed to investigate the prevalence, microbiological profile, and associated risk factors of HAIs among intensive care unit (ICU) patients in a referral hospital between January 2020 and December 2023. Medical records of 260 ICU patients were reviewed for demographic details, comorbidities, infection types, pathogens, and invasive device use. Forty patients (15.38%) developed HAIs with the highest prevalence in 2020 (50.0%). Infections were more common in males (56.5%) and those aged ≥56 years (54.6%). The predominant infections were catheter-associated urinary tract infections (47.5%), ventilator-associated pneumonia (35.0%), and central line-associated bloodstream infections (17.5%). Klebsiella pneumoniae (35.0%) and Acinetobacter baumannii (27.5%), pathogens commonly associated with multidrug resistance, were the most frequently isolated organisms. All HAI cases involved invasive device use with the use of three or more devices significantly increasing infection risk (p < 0.05). Additionally, 85% of infected patients had chronic conditions, primarily hypertension or diabetes. These findings emphasize the urgent need for strengthened infection control practices and targeted antimicrobial strategies to reduce HAIs and improve ICU patient outcomes in underreported regions.

Background/Objectives: Hypodermoclysis has gained increasing recognition as a safe, effective, and minimally invasive method for administering medication and fluids in palliative care. Despite its advantages, its adoption remains limited, primarily due to a lack of structured training resources for healthcare professionals. This study aimed to develop and validate an educational tool for training clinical nurses in hypodermoclysis administration in palliative care. Methods: This is a methodological study with a multi-methods approach. Study development involved a needs assessment with 48 professionals, a literature review, and the creation of a manual enriched with visual aids. Results: The material was validated by expert judges, technical reviewers, and the target audience. Organized into 21 chapters, the manual comprehensively addresses technical, theoretical, and ethical dimensions of the practice. Content validation by 14 experts yielded an outstanding global Content Validity Index (CVI) of 0.95. An independent evaluation of visual design by four communication specialists produced consistently high scores (91–96%), classifying the material as “superior” in quality. Feedback from target users (12 nurses) highlighted the manual’s clarity, applicability, and relevance. All constructive suggestions were incorporated into the final version. Conclusions: The resulting manual demonstrates strong validity as an educational resource, with significant potential to standardize and enhance hypodermoclysis training in palliative nursing, promoting both safety and humanized care.

Physical and mental health are intrinsically linked. However, healthcare systems, training programs, and clinical practice often operate in silos, creating structural disincentives that exacerbate morbidity, mortality, and economic burden. Integrated care models have consistently demonstrated improved outcomes, enhanced quality of life, and greater cost-effectiveness across a range of neuropsychiatric and chronic disorders. With the launch of the World Health Organization Brain Health Framework (2022) and the Swiss Brain Health Plan (2023–2033), important progress has been made toward integrating mental and brain health. However, current brain health concepts could be further strengthened by more explicitly incorporating the role of the body and physical health, including psychosomatic and social aspects, particularly in terms of their dynamic, bidirectional interactions with the brain. This article further outlines the health-related and economic benefits of integrated care, key challenges to the systematic implementation of mind–body integration within healthcare systems, and proposes strategic directions for embedding body–brain dynamics into research, education, and policy. This includes interdisciplinary teaching, harmonized conceptual models, composite clinical metrics, transferable interventions, and the removal of systemic barriers to establish integrated care pathways and reduce stigma through patient-centered empowerment. Ultimately, the “no health without brain health” ethos demands the conceptual and practical integration of dynamic, bidirectional body–brain interactions. Full article

Particulate matter (PM), a complex mixture of solid particles and liquid droplets, originates from both natural sources, such as sand, pollen, and marine salts, and anthropogenic activities, including vehicle emissions and industrial processes. While PM itself is not inherently toxic in all its forms, it often acts as a carrier of xenobiotic toxicants, such as heavy metals and organic pollutants, which adhere to its surface. This combination can result in synergistic toxic effects, significantly enhancing the potential harm to biological systems. Due to its small size and composition, PM can penetrate deep into the respiratory tract, acting as a physical “shuttle” that facilitates the distribution and bioavailability of toxic substances to distant organs. The omnipresence of PM in the environment leads to unavoidable and constant exposure, contributing to increased morbidity and mortality rates, particularly among vulnerable populations like the elderly, children, and individuals with pre-existing health conditions. This exposure also imposes a substantial financial burden on healthcare systems, as treating PM-related illnesses requires significant medical resources and leads to higher healthcare costs. Addressing these challenges necessitates effective mitigation strategies, including reducing PM exposure, improving air quality, and exploring novel approaches such as AI-based exposure prediction and nutritional interventions to protect public health and minimize the adverse effects of PM pollution.

Background and Rationale: Visceral disorders, both functional and organic, significantly impact health-related quality of life and pose a challenge for healthcare systems. Osteopathy offers manual, systemic, and patient-centered approaches for their management, yet these remain controversial due to limited scientific support and methodological inconsistencies. In the evolving landscape of healthcare regulation in Europe, and particularly in Italy, exploring clinical reasoning and operational models in visceral osteopathy is essential. This study aimed to explore the beliefs, clinical reasoning, and management strategies of experienced Italian osteopaths in the treatment of visceral disorders using a Constructivist Grounded Theory approach. Methods: This qualitative study applied a Constructivist Grounded Theory approach to explore the beliefs and clinical practices of 10 experienced Italian osteopaths. Semi-structured interviews were transcribed, coded, and thematically analyzed, integrating literature comparisons to support theory generation. Results: Four core themes emerged: (1) education and professional development, (2) definition and identification of visceral disorders, (3) clinical management strategies, and (4) multidisciplinary collaboration. The findings reveal marked heterogeneity in diagnostic frameworks and treatment rationales, often driven by tradition and subjective interpretation rather than empirical evidence. Palpatory assessments were frequently prioritized over patient-reported outcomes. Conclusion: The study highlights substantial fragmentation in Italian visceral osteopathic practice, echoing challenges across Europe. Promoting a shift towards critical thinking, evidence-based models, shared terminology, and interprofessional integration is essential for contextualising osteopathic contributions to the care of individuals presenting with visceral-related problems. These findings provide insights into the fragmented clinical practices of Italian osteopaths and may contribute to shaping a more critical and evidence-informed approach within Italian osteopathic practice and professional development, which is now more relevant than ever, given the recent integration of osteopathy into the Italian higher education system.

The World Health Organization (WHO) declared snakebite envenoming (SBE) as a neglected tropical disease in 2017. Antivenom is the gold standard of treatment, but many healthcare barriers exist, and hence, affected populations are often unable to access it. The challenge is further perpetuated by the lack of attention from national health authorities, poor regulatory systems and policies, and mismanagement of antivenom. This study aims to map the evidence regarding snake antivenom regulations globally and identify gaps in the literature to inform future research and policy. This review was conducted using the original Arksey and O’Malley framework by three independent reviewers, and the results were reported using the Preferred Reporting Items for Systematic reviews and Meta-Analysis Extension for Scoping Reviews (PRISMA-ScR). A search strategy was developed with assistance from a librarian, and six databases were searched: PubMed, SCOPUS, ProQuest Central, Africa Wide Web, Academic Search Output, and Web of Science. Screening was conducted independently by the reviewers, using Rayyan, and conflicts were resolved with discussions. A total of 84 articles were included for data extraction. The major themes that emerged from the included studies were regarding antivenom availability, accessibility, manufacturing, and regulations. The study revealed massive gaps in terms of policies governing antivenom management, especially in Asia and Africa. The literature does not offer sufficient evidence on management guidelines for antivenom in the endemic regions, despite identifying the challenges in supply. However, significant information from Latin America revealed self-sufficient production, involvement of national health bodies in establishing efficient regulations, effective distribution nationally and regionally, and technology sharing to reduce SBE-related mortality.

Background: Healthcare professionals experience high levels of stress due to demanding work, especially in metropolitan areas. Nature-based interventions offer potential mental health benefits. This randomized intervention study aimed to evaluate the effects of nature immersion therapies on mental health outcomes in healthcare workers with different psychological risk in Bogota, Colombia. Methods: During a period of 6 months, a total of 82 healthcare workers from two institutions were assigned to three groups: two exposed weekly to nature (parks and forests) and one control group with monthly conventional interventions. Psychological assessments of stress, anxiety, fatigue, and sleep quality were conducted at three time points (baseline, three, and six months of intervention). Cortisol Awakening Response (CAR) was measured monthly using immunoassay. Results: A decrease in the proportion of participants reporting high levels of perceived stress was observed in both intervention groups. Both forest and parks interventions significantly reduced anxiety and fatigue, while sleep quality improved only in the forest group. Multivariate analysis found a negative association between fatigue and forest intervention, as well as significant differences in CAR concentrations across groups over time. Conclusions: This study provides evidence that nature immersion therapy, particularly urban forests, positively impact mental and physical health, reducing stress, anxiety, fatigue, and CAR levels, and could be considered as an effective intervention to enhance workers’ resilience to stress, benefiting their overall health and well-being.

Background: Klebsiella pneumoniae represents a major cause of healthcare-associated infections in intensive care units, with resistance profiles ranging from multidrug-resistant to extensively drug-resistant and pandrug-resistant. Critically ill patients, who often require invasive devices and prolonged antibiotic therapy, are especially vulnerable to colonization and infection by these strains. Surveillance data on resistance trends and specimen-specific patterns in Romanian intensive care units (ICUs) remain limited. Methods: We conducted a four-year surveillance study (2021–2024) in a tertiary Romanian ICU, analyzing K. pneumoniae isolates collected from diverse clinical specimens. Resistance phenotypes were classified as MDR, XDR, PDR, or susceptible based on standard definitions. Trends over time were assessed using Cramér’s V and correspondence analysis, while stratification by specimen type evaluated associations between anatomical site and resistance profiles. Results: A total of 254 K. pneumoniae isolates were analyzed. MDR strains predominated in 2021 and 2022 but sharply declined by 2024 (from 80% to 8.3%). In parallel, XDR and PDR phenotypes increased substantially, indicating a shift toward more complex resistance profiles. A significant temporal association was found (Cramér’s V = 0.43), with 2024 marked by a sharp decline in MDR isolates and a predominance of XDR and PDR phenotypes, reflecting an advanced resistance profile. Specimen-type analysis showed tracheal aspirates as the main reservoir for resistant strains, followed by urine and blood cultures, with a weaker but meaningful association (Cramér’s V = 0.24). Conclusions: These findings reveal a change in resistance patterns in ICU-acquired K. pneumoniae infections, with MDR strains being displaced by XDR and PDR phenotypes. These findings highlight the urgent need for time- and specimen-informed resistance monitoring and adaptive antimicrobial stewardship. Without targeted interventions, gains made in controlling MDR strains risk being rapidly eclipsed by the spread of highly resistant organisms. Full article

Background/Objectives: The World Health Organization’s Surgical Safety Checklist (WHO SSC) is known to reduce surgical complications and mortality, yet its implementation remains inconsistent across institutions. This study evaluated compliance with a modified SSC and assessed the impact of structured interventions to improve adherence at the University Hospital of Split, Croatia. Methods: A before-and-after study analyzed a sample of 1437 completed SSCs over four time points between April 2024 and May 2025: the baseline and after three successive interventions (an official letter from the hospital director emphasizing mandatory SSC use, individual meetings with department heads and head nurses reinforcing its importance, and a quality audit review of SSC completeness with leadership). Checklist completeness was assessed across five SSC sections: General Information, Sign In, Time Out, Sign Out, and Staff Info. Results: Overall checklist completeness increased from 78.3 ± 8.5% at baseline to 86.3 ± 2.5%, 92.0 ± 3.8%, and 94.7 ± 4.8% after the first, second, and third interventions, respectively (p < 0.001). All checklist sections improved significantly: General Info rose from 91.1 ± 6.0% to 98.6 ± 2.6% (p < 0.001); Sign In from 85.0 ± 11.4% to 97.0 ± 3.5% (p = 0.002); Time Out from 79.0 ± 14.6% to 96.4 ± 6.5% (p < 0.001); Sign Out from 70.2 ± 11.2% to 87.7 ± 11.0% (p = 0.003); and Staff Info from 70.7 ± 12.9% to 100.0 ± 0.0% (p < 0.001). Post hoc testing confirmed significant gains versus baseline for all three interventions (Dunnett’s test), with a further significant improvement between the first and third interventions (Tukey’s HSD, p = 0.011). Conclusions: Structured, low-cost interventions emphasizing administrative support, education, and communication significantly improved SSC adherence across a large tertiary hospital. This initiative represents a pioneering effort in Croatia and offers a scalable model for similar public healthcare systems aiming to enhance patient safety. Full article

Background/Objectives: Occupational well-being and professional quality of life are essential for healthcare sustainability. While clinical staff are presumed to experience higher stress, few studies have compared their experience to that of non-clinical personnel within the same institution. Methods: This observational study involved 63 employees from an Italian research hospital: 36 healthcare workers in critical care and 27 administrative staff. Participants completed the Brief Coping Orientation to Problems Experienced Inventory (Brief COPE), an ad hoc organizational questionnaire, and the ProQoL Version 5 (administered to clinical staff only). Non-parametric tests (Mann–Whitney U and Chi-square) were used to explore group differences. Results: No significant differences emerged between groups in coping styles or strategies. Significant differences were observed only in reports of work-related injuries (42% of healthcare staff vs. 4% of administrative staff; p = 0.002) and perceived disruption caused by vacation requests (64% vs. 26%; p = 0.006). Other organizational indicators such as job dissatisfaction, intention to leave, or perceived managerial support did not differ significantly. ProQoL results showed that 53% of healthcare workers had moderate to high burnout, and 47.2% scored high on compassion fatigue, while only 2.7% showed high levels of secondary traumatic stress. Conclusions: Despite distinct operational contexts, healthcare and administrative staff reported broadly similar experiences in terms of coping and organizational well-being. These findings challenge assumptions of stark differences across professional roles and suggest that workplace well-being strategies should address the needs of both clinical and non-clinical staff.

Background/Objectives: Transitioning from pediatric to adult services can be challenging for youth with complex chronic health conditions, especially those with multi-morbidity. These youth often require extra coordination and support during this phase of their healthcare journey. Building upon existing provincial and national initiatives for transitions from pediatric to adult healthcare services, we have developed a hospital-wide program within one of Canada’s largest children’s hospitals that incorporates an integrated care model aimed at better serving these patients and improving outcomes. Methods: Guided by provincial quality standards, an environmental scan and knowledge user engagement were conducted to develop the program, followed by an implementation phase, where the model was piloted. Ongoing learnings from the pilot continue to inform program implementation and evaluation. Results: The Transition to Adult Care (TAC) program offers disease-agnostic care to youth with complex needs for 1–3 years, including 1-year post-transfer, addressing the fragmentation of care across multiple services, organizations and providers. Our interdisciplinary team works in partnership with youth and caregivers to deliver transition navigation, easing the burden on patients and families by tailoring transition supports to each individual youth and caregiver. Preliminary data from the pilot revealed a lack of awareness about transition resources and timelines; however, with early engagement and flexible support beyond age 18, youth were able to complete their transition successfully. Conclusions: The TAC program demonstrates a systems-level approach to improving transition to adult care for youth with complex health needs by integrating individualized support, cross-sectoral collaboration, and continuous quality improvement. Early engagement, flexible post-transfer support, and close partnership with youth, caregivers, and providers are key to facilitating transition. These learnings can inform broader implementation efforts and help address persistent gaps in transitional care across healthcare systems. Full article

Background: Coronavirus Disease 2019 has been associated with dysfunction in multiple endocrine organs, including the thyroid gland. While evidence suggests SARS-CoV-2 may influence thyroid function and promote oncogenesis through inflammation and cytokine storms, its role in thyroid cancer remains unclear. This study investigates whether COVID-19 is associated with an increased risk of thyroid cancer development. Methods: We conducted a retrospective cohort study using the TriNetX global federated health research database, encompassing data from 151 healthcare organizations. Adult patients with confirmed COVID-19 between 1 December 2019 and 31 December 2023, were included and compared to a matched cohort without COVID-19. Patients with prior thyroid cancer history or who had received COVID-19 vaccination were excluded in both groups. Propensity score matching (1:1) was performed for age, gender, and overweight/obesity status. The primary outcome was that new-onset thyroid cancer was diagnosed at least one year after COVID-19 diagnosis. Hazard ratios were calculated using Cox proportional hazards models, and subgroup analyses were performed based on age, gender, thyroid function status and treatment modalities. Results: After matching, a significantly higher thyroid cancer incidence was observed between the post-COVID and non-COVID groups. Subgroup analysis revealed a significantly higher risk of thyroid cancer development following COVID-19 diagnosis in patients who developed hyperthyroidism (HR 2.14, 95% CI: 1.04–4.46) or hypothyroid-ism (HR 1.83, 95% CI: 1.12–2.97) compared with the non-COVID population. Male patients also exhibited a higher risk of thyroid cancer after COVID-19 (HR 1.22, 95% CI 1.02–1.46). For patients with hyperthyroidism or hypothyroidism, those who had prior COVID-19 exhibited a relatively higher risk of developing thyroid cancer than those without a history of COVID-19 (HR 4.387, 95% CI: 2.08–9.24 for hyperthyroidism; HR 2.58, 95% CI: 1.58–4.22 for hypothyroidism). Conclusions: Patients with COVID-19 exhibited an increase in thyroid cancer risk, with specific subgroups—male adults and those with post-infectious thyroid dysfunction—also exhibiting increased risk. These findings suggest a potential relationship between SARS-CoV-2 and thyroid oncogenesis, warranting further prospective research. Full article

(1) Background: The COVID-19 pandemic presented unprecedented challenges for people with multiple sclerosis (PwMS) in Oman, necessitating targeted healthcare planning and patient support. This study aimed to investigate the impact of COVID-19 on MS management and disease course, incidence, and outcomes of COVID-19, psychosocial and mental health effects of the pandemic, and demographic and clinical predictors of the effects related to COVID-19 among Omani PwMS. (2) Methods: This cross-sectional study was conducted from January to April 2021. Adult (18–60 years) Omani PwMS completed a structured interview along with the Expanded Disability Status Scale (EDSS) and World Health Organization Well-being Index (WHO-5). Clinical data on relapses and disease-modifying therapies and adherence were analyzed. The data was statistically analyzed. (3) Results: Of 104 PwMS (73.1% female), 22.1% contracted COVID-19, with fatigue being the most reported symptom (87%). Female sex (p = 0.042), younger age (18–34 vs. 35–45 years; p = 0.014), diagnosis of COVID-19 (p = 0.037), and low current mental well-being scores (p = 0.021) predicted greater COVID-19-related effects. (4) Conclusion: These findings highlight the need to study the mental resilience of this subgroup of PwMS and provide them with targeted support during crises. Full article

The increasing prevalence of chronic metabolic diseases poses a significant challenge in the modern world, impacting healthcare systems and individual life expectancy. The World Health Organization (WHO) recommends that older adults (65+ years) engage in 150–300 min of moderate-intensity or 75–150 min of vigorous-intensity physical activity, alongside muscle-strengthening and balance-training exercises at least twice a week. However, nearly one-third of the adult population (31%) is physically inactive, which increases the risk of developing obesity, type 2 diabetes, cardiovascular diseases, hypertension, and psychological issues. Physical activity in the form of aerobic exercise, resistance training, or a combination of both is effective in preventing and managing these metabolic diseases. In this review, we explored the effects of exercise training, especially on respiratory and pulmonary factors, including oxygen consumption, pulmonary ventilation, and blood gas analyses among adults. During exercise, oxygen consumption can increase up to 15-fold (from a resting rate of ~250 mL/min) to meet heightened metabolic demands, enhancing tidal volume and pulmonary efficiency. During exercise, the increased energy demand of skeletal muscle leads to increases in tidal volume and pulmonary function, while blood gases play a key role in maintaining the pH of the blood. In this review, we explored the influence of age, body composition (BMI and obesity), lifestyle factors (smoking and alcohol use), and comorbidities (diabetes, hypertension, neurodegenerative disorders) in the modulation of these physiological responses. We underscored exercise as a potent non-pharmacological intervention for improving cardiopulmonary health and mitigating the progression of metabolic diseases in aging populations. Full article
