Background: Emotional safety is increasingly recognized as crucial for high-quality patient care, encompassing a patient’s sense of security, courteous treatment, being heard, and a peaceful environment. Purpose: The purpose of this study was to explore the perceptions of patients and providers (doctors and nurses) regarding emotional harm and safety in relation to hospitalized patients. Methods: We conducted a qualitative study in public-sector teaching hospitals in Peshawar, Pakistan. Data were collected after we obtained informed consent using individual interviews with 15 providers, namely, doctors (n = 7) and nurses (n = 8), and five focus group discussions (FGDs) with 25 hospitalized patients. Data from both the interviews and FGDs were analyzed using Braun and Clarke’s six-phase approach to thematic analysis. Results: The key themes revealed by the providers’ perspectives were factors contributing to emotional harm, staff-related factors, coping mechanisms and solutions, and the impact of prior experiences and involvement. The main themes that emerged from the patients’ perspectives were anxiety upon admission, the impact of communication, emotional stress due to treatment delays, systemic/bureaucratic challenges, financial burden, a lack of emotional support, and post-hospitalization concerns. The consistent perspectives shared by both patients and providers included the impact of systemic factors, communication issues, the role of staff attitude/behavior, financial concerns, and the influence of prior experiences. Conclusions: This study highlights the complex interplay of systemic, staff-related, and patient-specific factors. It suggests a need to improve communication, staff support, administrative processes, financial counseling, emotional support integration, and discharge planning to minimize harm and create a patient-centered environment.

Background: Diabetes mellitus is a chronic metabolic disorder that increases mortality and morbidity rates. Infections of the hand can easily cause long-term morbidity and dysfunction, but despite their associated high morbidity, diabetic hand infections are more neglected than diabetic foot infections. Objectives: This study was conducted over a one-year follow-up period, considering the total costs of treatment over one year post discharge for patients with diabetic hand infections that required surgery. A Monte Carlo Simulation was used in this study as a sensitivity analysis of all the cost calculations. Materials and Methods: A total of 62 out of 75 patients were diagnosed with Type 2 diabetes; 11 were female, and 64 were male. Out of all the patients, 15 visited outpatient clinics 30 times or more, and due to their recurrent visits, the outpatient treatment costs reached USD 5162.41 ± 3838.55. The total cost incurred over the period from the patients’ first hospitalization to the completion of all treatments and the end of the one-year follow-up was USD 24,602.22 ± 5257.15. Conclusions: The cost of hospitalization was the most important factor affecting the total expenses. Therefore, taking precautions before a diabetic hand infection occurs, or when one does occur, performing treatment without delay is expected to reduce the economic burden. Full article

Background: While Asia contributes 44.3% of traumatic brain injuries (TBI) worldwide, data regarding Asian TBI inpatient rehabilitation length of stay (RLOS) is scarce. A retrospective cohort study was conducted to determine correlates of inpatient RLOS (days) and prolonged RLOS >30 days (PRLOS > 30). (2) Methods: Data extraction of discharged inpatient records was performed from 2018 to 2024. Dependent variables included RLOS (days) and PRLOS > 30. Independent variables included demographic characteristics, TBI severity (emergency-room Glasgow Coma Scale-GCS), admission/discharge Functional Independence Measure (FIM), intra-rehabilitation complications, post-traumatic amnesia (PTA) duration, and discharge placement. (3) Results: Altogether, 289 data sets were analysed, median (IQR) age, 64 (28) years, 78.9% (228/289) males, and 79.6% (230/289) Chinese. Median (IQR) RLOS was 28 (21) days, with PRLOS >30 at 39.8% (115/289); RLOS of 44 (19.5) days. PRLOS > 30 was significantly associated with PTA duration >28 days (OR 4.01, 95% CI 1.90–8.45, p < 0.001), admission FIM ≤ 40/126 (OR 4.71, 95% CI 2.32–9.59, p < 0.001), delayed neurosurgical complications (OR 4.74, 95% CI 1.28–17.6, p = 0.02) and discharge to non-home destination (OR 2.75. 95% CI 1.12–6.76, p = 0.03). (4) Conclusion: PRLOS >30 was significantly associated with longer PTA > 4 weeks, lower admission FIM score, delayed neurosurgical complications, and discharge to a nursing home. Full article

Background/Objectives: Developmental dysplasia of the hip (DDH) affects 1–3% of newborns and requires early detection for optimal outcomes. DDH involves abnormal acetabular–femoral congruence between the acetabulum and femoral head, resulting from either shallow acetabular development or delayed femoral ossification of the femoral head. We evaluated the ossification nucleus of the femoral head (ONFH) to determine prevalence, radiographic timing, and associations with perinatal factors. Methods: We analyzed 100 pelvic radiographs of infants between 90 and 150 days of age. Participants were selected by convenience sampling, based on inclusion criteria. We identified the presence of ONFH and measured biometric parameters, morphology, and anatomical location. Sociodemographic and perinatal data were collected from the participating infants. Results: The prevalence of ONFH was 33%, and the mean age at visualization was 104 days. The presence of ONFH was correlated with birth weight (p = 0.011), discharge weight (p = 0.005), and weight at 1 month (p = 0.034). In our study, female sex (p = 0.004) was associated with a 4.966-fold higher odds of ONFH prevalence compared to males. Conclusions: This study provides relevant evidence regarding the prevalence, morphology, and characteristics of ONFH. Few studies report this information on ONFH in different populations. The optimal timing for radiographic visualization of ONFH in infants remains undefined, but the appearance of the ONFH was concentrated around 104 days of life. The novel association between weight and ONFH provides new insights into DDH. This provides new insights for DDH screening. This association warrants further research for the early detection of DDH.

Investigating the coupled hydrodynamic and thermal wakes induced by underwater vehicles is vital for non-acoustic detection and environmental monitoring. Here, the standard SUBOFF model is simulated under eight operating conditions—speeds of 10, 15, and 20 kn; depths of 10, 20, and 30 m; and both with and without thermal discharge—using Delayed Detached Eddy Simulation (DDES) coupled with the Volume of Fluid (VOF) method. Results indicate that, under heat emission conditions, higher speeds accelerate wake temperature decay, making the thermal wake difficult to detect downstream; without heat emission, turbulent mixing dominates the temperature field, and speed effects are minor. With increased speed, wake vorticity at a fixed location grows by about 30%, free-surface wave height rises from 0.05 to 0.15 m, and wavelength remains around 1.8 m, all positively correlated with speed. Dive depth is negatively correlated with wave height, decreasing from 0.15 to 0.04 m as depth increases from 5 to 20 m, while wavelength remains largely unchanged. At a 10 m submergence depth, the thermal wake is clearly detectable on the surface but becomes hard to detect beyond 20 m, indicating a pronounced depth effect on its visibility. These results not only confirm the positive correlation between vessel speed and wake vorticity reported in earlier studies but also extend those findings by providing the first quantitative evaluation of how submergence depth critically limits thermal wake visibility beyond 20 m. This research provides quantitative evaluations of wake characteristics under varying speeds, depths, and heat emissions, offering valuable insights for stealth navigation and detection technologies.

This paper presents the results of a numerical study on transient temperature distributions and phase fractions in a thermal energy storage unit containing phase change material (PCM). The latent heat storage unit (LHSU) is a compact shell-and-tube exchanger featuring seven tubes arranged in a staggered layout. Three organic phase change materials are investigated: paraffin LTP 56, fatty acid RT54HC, and fatty acid P1801. OpenFOAM software is utilized to solve the governing equations using the Boussinesq approximation. The discretization of the equations is performed with second-order accuracy in both space and time. The three-dimensional (3D) computational domain corresponds to the inner diameter of the LHSU. Calculations are conducted assuming constant thermal properties of the fluids. The experimental and numerical results indicate that for paraffin LTP56, the charging time is approximately 8% longer than the discharging time. In contrast, the discharging times for fatty acids RT54HC and P1801 exceed their charging times, with time delays of about 14% and 49% for RT54HC and 25% and 30% for P1801, according to experimental and numerical calculations, respectively.

Botulism is a severe muscle paralysis disease mediated by the botulinum toxin. Here, we reported a foodborne botulism case caused by Clostridium botulinum subtype A5(b3) from self-packaged vacuum spicy rabbit heads. Treatment for this case was delayed due to misdiagnosis and insufficient diagnostic capacity in three hospitals, which resulted in progressive clinical deterioration, and eventually, the patient was transferred to Shandong Public Health Clinical Center for specialized therapy. The case was suspected as foodborne botulism by the Qilu Medical-Prevention Innovation Integration pathway and multi-disciplinary consultation. An epidemiological investigation and laboratory confirmation revealed that the botulinum neurotoxin originated from vacuum-packaged spicy rabbit heads distributed via interprovincial cold chain logistics. After treatment with botulism antiserum, the patient’s condition significantly improved, and they were discharged after recovery. We revealed that this foodborne botulism outbreak was caused by the Clostridium botulinum A5(b3) subtype from food by whole-genome sequencing and SNP typing. All the strains belonged to Group I carrying the botulinum neurotoxin gene classified as the ha cluster. Toxin A was confirmed by MBA and other methods, while toxin B was non-functional due to the truncated bont/B gene. Other virulence genes and antibiotic resistance genes were also detected. Our findings indicate that self-packaged vacuum meat products represent an emerging risk factor for botulism transmission when stored improperly. Importantly, the recurrent misdiagnosis in this case underscored the urgent need to enhance the training of healthcare professionals in medical institutions to improve the diagnostic accuracy and clinical management of botulism.

Rainfall–runoff processes and flood propagation were quantified to clarify floodwater dynamics in the upper Tenryu River basin. The basin is characterized by contrasting runoff behaviors between its left- and right-bank subbasins and large upstream river storage created by gorge topography. Radar rainfall and dam inflow data were analyzed to determine the runoff characteristics, on which the rainfall–runoff simulation was based. A higher storage capacity was observed in the left-bank subbasins, while an exceptionally large specific discharge was observed in one of the right-bank subbasins after several hours of intense rainfall. Based on these findings, the basin-scale storage was quantitatively evaluated. Water level peaks in the main channel appeared earlier at downstream locations, indicating that tributary inflows strongly affect the flood peak timing. A two-dimensional unsteady model successfully reproduced this behavior and captured the delay in the flood wave speed due to the complex morphology of the Tenryu River. The average α value, representing the ratio of flood wave speed to flow velocity, was 1.38 over the 70 km study reach. This analysis enabled quantification of river channel storage and clarified its relative relationship to basin storage, showing that river channel storage is approximately 12% of basin storage.

Background: Human cytomegalovirus (HCMV) is the leading cause of congenital and acquired viral infections in newborns. While acquired infections are often asymptomatic, premature infants—especially those born before 30 weeks of gestation or with a very low birth weight (<1500 g)—are at an increased risk for severe infections. These can manifest as thrombocytopenia, liver failure, sepsis-like symptoms, and, in rare cases, death. HCMV is transmitted through various human secretions, including breast milk, which is the optimal feeding method for premature infants. Methods: We present five premature neonates, born between 23 and 26 weeks of gestation, each with a distinct clinical presentation of acquired HCMV infection. Results: All infants tested negative for congenital CMV infection via molecular urine testing within the first three weeks of life. Acquired infection was diagnosed between the second and third month of life, with symptoms such as septic shock, persistent thrombocytopenia, and signs of liver failure. Each infant received antiviral treatment along with regular viral load monitoring. Unfortunately, one patient died due to complications of prematurity. The remaining infants were discharged and continue to receive follow-up care in an outpatient clinic. Conclusions: These cases of postnatally acquired CMV infection aim to increase awareness of its highly heterogeneous and nonspecific clinical presentation, which may result in an incorrect, delayed, or concealed diagnosis. Currently, there are no clear guidelines on how to manage the presence of the virus in maternal breast milk, particularly for premature infants. It should be recommended to perform a molecular CMV test in all breast-fed preterm infants who present with sepsis-like symptoms, thrombocytopenia, liver failure, or other organ involvement. In case of a confirmed aCMV diagnosis, appropriate treatment should be introduced. Full article

The biological aging of titanium implants, marked by increased surface hydrophobicity and organic contamination, reduces bioactivity and delays osseointegration. A major challenge in implant dentistry is determining how to preserve surface hydrophilicity during storage, as conventional atmospheric conditions accelerate surface degradation. This pilot in vivo study aimed to evaluate ozone nanobubble water (NBW3) as a storage medium to prevent biological aging and enhance the early-stage osseointegration of glow discharge-treated titanium implants. Screw-type implants were stored in either NBW3 or atmospheric conditions and then implanted into femoral bone defects in Sprague Dawley rats. Removal torque testing, scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), and histological analysis of bone-to-implant contact (BIC) were performed 14 and 28 days post-implantation. At 14 days, the NBW3-stored implants demonstrated significantly higher removal torque (2.08 ± 0.12 vs. 1.37 ± 0.20 N·cm), BIC (65.74 ± 12.65% vs. 44.04 ± 14.25%), and Ca/P atomic ratio (1.20 ± 0.32 vs. 1.00 ± 0.22) than the controls. These differences were not observed at 28 days, indicating NBW3’s primary role in accelerating early osseointegration. The findings suggest that using NBW3 is a simple, effective approach to maintain implant surface bioactivity during storage, potentially improving clinical outcomes under early or immediate loading protocols.

In some regions, extreme heat can result in pavement temperatures that are high enough to cause severe burn injuries within seconds of skin contact. This risk is elevated for unhoused individuals who may lack adequate clothing and shelter and have susceptibility to other risk factors, including substance use and in turn loss of consciousness. While prior studies have shown worse outcomes for unhoused individuals due to delays in care and higher susceptibility, there is a lack of data on the impact of pavement burns specifically within this population. This single-institution retrospective cohort study aims to explore burn severity and hospital outcomes in housed vs. unhoused patients with pavement burns. The data were analyzed using independent samples t-tests and logistic regression when appropriate, with p < 0.05 considered statistically significant. A total of 305 individuals met the inclusion/exclusion criteria and comprised the final study cohort, 17.7% of which were unhoused. There was no significant difference in TBSA, survival to discharge, or hospital length of stay between housed and unhoused patients. While unhoused individuals may still be at heightened risk for pavement burns due to exposure to extreme heat and a lack of protective measures, these results may additionally suggest consistent emergency care for patients regardless of housing status. Furthermore, these results highlight the importance of developing targeted outreach and prevention programs and equitable emergency care protocols for vulnerable populations. Full article

Background: Cutaneous squamous cell carcinoma (SCC) is the most common primary malignant tumor of the hand, and its aggressive nature can lead to significant morbidity, particularly when affecting critical structures like the thumb. SCC in this location may arise in the periungual area or the pulp and frequently presents with non-specific symptoms such as swelling, nail deformity, or discharge, features that closely mimic common benign conditions. Methods: A retrospective study analyzed patients with neglected or misdiagnosed SCC of the thumb treated at the Hand and Microsurgery Unit of the Jewish Hospital, Rome, between 2015 and 2025. Patient demographics, duration from symptom onset to diagnosis, initial misdiagnoses, and imaging findings (X-rays, MRI, CT scans, lymph node sonography) were reviewed. Surgical interventions, histopathological grading, and postoperative management were documented, with long-term follow-up focusing on disease progression and patient survival. Results: Sixteen patients were included in the study. The mean age at surgery was 73.6 years (range: 55–93 years), with a mean delay of 8.2 months from symptom onset to diagnosis in 87.5% of cases. Initial misdiagnoses included verruca vulgaris, onychomycosis, paronychia, and osteomyelitis. Imaging consistently revealed soft tissue involvement, bony invasion, and occasional metastasis. Surgical approaches ranged from wide resection to amputation, with thumb reconstruction in selected cases and hand amputation in severe presentations. Long-term follow-up (mean 4.6 years) showed high morbidity, a reduction in hand function and QoL, and a 50% mortality rate, with two cases due to metastatic disease (12.5%). Conclusions: Thumb SCC presents diagnostic and therapeutic challenges, exacerbated by late diagnosis and initial misdiagnoses. Multidisciplinary management involving early recognition, comprehensive imaging, appropriate surgical interventions, and vigilant follow-up is crucial for optimizing outcomes. Full article

Background: Emergency laparoscopic cholecystectomy (ELC) has emerged as a viable alternative to delayed elective surgery for acute gallstone disease, although its widespread adoption is hindered by cultural barriers. This study compares outcomes between elective and emergency laparoscopic cholecystectomy and evaluates the impact of implementing an ELC pathway on elective waiting times, patient outcomes, and overall service delivery. Methods: A prospective cohort study was conducted between December 2021 and December 2023, including all patients undergoing emergency or elective laparoscopic cholecystectomy. One-to-one propensity score matching, correlation statistics, and multivariate logistic regression were used to analyse outcomes. Results: Of 585 patients, 314 (53.4%) underwent emergency and 271 (46.3%) elective cholecystectomies. After matching, 474 patients were analysed (237 per group). The ELC pathway achieved an 81.4% first-presentation procedure rate, with 69.2% managed as day cases and 84.4% discharged the following day. Emergency cases had longer operative times (+9 min), higher rates of subtotal cholecystectomy (8.9% vs. 3.0%, p < 0.001), and more frequent postoperative ERCP (16.9% vs. 4.6%, p < 0.001). Other outcomes were comparable. Introduction of the ELC pathway significantly reduced elective waiting times from a median of nine to three months (R = −0.219, R² = 0.059, p < 0.001) and preoperative admissions (IQR 0–1, R = −0.223, R² = 0.050, p = 0.002). Conclusions: An ELC pathway is a safe and effective alternative to elective gallstone surgery, offering substantial benefits to patients and healthcare systems, while serving as a strategic, cost-conscious approach to reducing surgical waiting times and preoperative admissions. Its success hinges upon surgical expertise in acute decision making, skill in performing subtotal cholecystectomy, and access to institutional resources such as advanced imaging and ERCP services.

Healthcare is a dynamic and ever-changing phenomenon and is subject to multiple challenges, particularly concerning sustainability and cost issues. The literature identifies bed space and problems related to the lack of hospital beds as being directly or indirectly related to both admission and discharge processes, with delays in in-patient discharges being identified as a variable of significance when it comes to a health system’s overall performance. In this respect, the aim of this research was to explore factors related to delayed discharges in an acute hospital setting in Malta, a small European member state, through the perspectives of health professionals. This study followed a qualitative approach. Semi-structured interviews (n = 8) and focus groups (n = 2) were conducted with a diverse group of experienced health professionals. Informed consent was obtained from all participants, and all data were treated with strict confidentiality throughout the study. The sample was limited to professionals working in adult, non-specialized healthcare settings. Manual thematic analysis was carried out. Codes were grouped to derive seven main themes, which were identified after carrying out the thematic analysis process on the transcripts of the interviews/focus groups. The derived themes are the following: (a) a faulty system, which is open to abuse and inefficiency, (b) procedural delays directly impacting delayed discharges, (c) long-term care/social cases as a major cause of delayed discharges, (d) the impact of external factors on delayed discharges, (e) stakeholder suggestions to management to counteract delayed discharges, (f) the impact of COVID-19 on delayed discharges, and (g) inter-professional relationships. Factors related to delayed discharges and the effects of delayed discharges on the hospital emerged from the main findings, together with specific potential interventions to minimise delays in discharge. Health professional interactions and the effects of inter-professional relationship setbacks on delayed discharges were explored, and the impact of the COVID-19 pandemic on hospital dynamics and additional delays were also addressed. This information is intended to provide hospital administrators with data-driven internal organisational evidence to guide them through changes and to inform future decisions regarding hospital performance and efficiency from a discharge delay perspective.

Background/Objectives: We sought to determine if glibenclamide, a sulfonylurea receptor 1-transient receptor potential melastatin 4 (SUR1-TRPM4) channel blocker, reduces cerebral edema and improves neurological functioning in aneurysmal subarachnoid hemorrhage (aSAH). Methods: Following Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines, a systematic search was conducted in PubMed, Cochrane Library, Web of Science, and SCOPUS for studies evaluating glibenclamide in aSAH patients. Primary outcomes included scores on the modified Rankin Scale (mRS) at discharge and the Subarachnoid Hemorrhage Early Brain Edema Score (SEBES) at ten days post-intervention. Secondary outcomes included adverse events, and safety and efficacy endpoints. Random-effects models were employed for meta-analyses. Results: Three studies utilizing oral glibenclamide (n = 245) met inclusion criteria. Oral glibenclamide demonstrated no significant improvements in mRS scores [MD −0.19 with 95% CI (−2.05, 1.66)] at discharge, [MD 0.06, (−0.60, 0.71)] at 3 months, and [MD 0.4, (−0.67, 0.87)] at 6 months; functional independence [risk ratio (RR) 1.05, (0.81, 1.36)]; independent ambulation [RR 1.07, (0.77, 1.48)]; mortality [RR 0.79, (0.42, 1.50)]; or delayed cerebral ischemia [RR 0.58, (0.31, 1.09]). Hypoglycemia risk was significantly higher in the glibenclamide group [RR 3.92, (1.14, 13.49)]. Conclusions: Oral glibenclamide offers a novel approach to addressing cerebral edema in aSAH but shows limited clinical efficacy in improving functional and neurological outcomes in subtherapeutic doses. Its safety profile is acceptable, though hypoglycemia risk necessitates careful monitoring. Further research is required to optimize dosing, timing of intervention, and patient selection to enhance therapeutic outcomes. By contrast, intravenous administration of therapeutic doses of glibenclamide offers a promising avenue for future studies in the management of aSAH by taking advantage of the favorable pharmacokinetics of this route of administration.
