Background: Chronic Kidney Disease (CKD) is a major global health issue, with diabetes being its primary cause and cardiovascular disease contributing significantly to patient mortality. Recently, two classes of medications—sodium–glucose cotransporter 2 inhibitors (SGLT2i) and glucagon-like peptide-1 receptor agonists (GLP-1 RAs)—have shown promise in protecting both kidney and heart health beyond their effects on blood sugar control. Methods: We conducted a narrative review summarizing the findings of different clinical trials and mechanistic studies evaluating the effect of SGLT2i and GLP-1 RAs on kidney function, cardiovascular outcomes, and overall disease progression in patients with CKD and DKD. Results: SGLT2i significantly mitigate kidney injury by restoring tubuloglomerular feedback, reducing intraglomerular hypertension, and attenuating inflammation, fibrosis, and oxidative stress. GLP-1 RAs complement these effects by enhancing endothelial function, promoting weight and blood pressure control, and exerting direct anti-inflammatory and anti-fibrotic actions on renal tissues. Landmark trials—CREDENCE, DAPA-CKD, and EMPA-KIDNEY—demonstrate that SGLT2i reduce the risk of kidney failure and renal or cardiovascular death by 25–40% in both diabetic and non-diabetic CKD populations. Likewise, trials such as LEADER, SUSTAIN, and AWARD-7 confirm that GLP-1 RAs slow renal function decline and improve cardiovascular outcomes. Early evidence suggests that using both drugs together may offer even greater benefits through multiple mechanisms. Conclusions: SGLT2i and GLP-1 RAs have redefined the therapeutic landscape of CKD by offering organ-protective benefits that extend beyond glycemic control. Whether used individually or in combination, these agents represent a paradigm shift toward integrated cardiorenal-metabolic care. A deeper understanding of their mechanisms and clinical utility in both diabetic and non-diabetic populations can inform evidence-based strategies to slow disease progression, reduce cardiovascular risk, and improve long-term patient outcomes in CKD.

p-Cresyl sulfate (PCS), a gut-derived uremic toxin with proinflammatory and cytotoxic effects, has been implicated in cardiovascular injuries among patients with chronic kidney disease (CKD). Aortic stiffness (AS), assessed by carotid–femoral pulse wave velocity (cfPWV), is a recognized predictor of cardiovascular risk. This study investigated the association between serum PCS levels and AS in patients with nondialysis-dependent CKD. In total, 165 patients with nondialysis-dependent CKD were enrolled. Clinical data and fasting blood samples were collected. Arterial stiffness (AS) was assessed bilaterally by measuring carotid–femoral pulse wave velocity (cfPWV) on both the left and right sides. A value above 10 m/s was considered indicative of increased stiffness. Serum PCS levels were quantified using high-performance liquid chromatography–mass spectrometry. Fifty patients (30.3%) had AS. The AS group was significantly older and had higher diabetes prevalence, systolic blood pressure, fasting glucose, urinary protein-creatinine ratio, and PCS levels than the control group. In the multivariate analysis, both PCS (odds ratio [OR]: 1.097; 95% confidence interval [CI]: 1.024–1.175; p = 0.008) and age (OR: 1.057; 95% CI: 1.025–1.090; p < 0.001) were independently associated with AS. In conclusion, elevated serum PCS and older age were independently associated with AS. Thus, PCS is a potential early marker of vascular damage in CKD. Full article

Background/Objectives: The percutaneous insertion of an external ventricular drain (EVD) is a common neurosurgical procedure that is crucial in managing acute brain injuries because of the drain’s role in monitoring intracranial pressure and draining cerebrospinal fluid. The primary indication is acute hydrocephalus, which often results from subarachnoid hemorrhage, intracranial hemorrhage, traumatic brain injury, stroke, or infection. Standard EVD placement targets the frontal horn of the lateral ventricle. However, complications such as hemorrhage, infection, and catheter occlusion frequently arise, with occlusion rates ranging from 19% to 47%. Occlusion can lead to increased intracranial pressure, necessitating interventions such as saline flushes or fibrinolytic drug administration. The placement of an EVD is a very specific choice that must be tailored to the individual patient, often in scenarios in which multiple interpretations of the data are possible: the question of which patient is eligible for EVD placement may be subjective. Intraventricular fibrinolysis (IVF) with urokinase-type plasminogen activator (uPA) or tissue-type plasminogen activator is used with the aim of lysing intraventricular clots and preventing EVD occlusion. Despite numerous studies, conclusive evidence on their efficacy is lacking. The CLEAR III trial confirmed the safety of IVF but showed uncertain benefits in neurological outcomes. Given the limited literature on uPA, this study evaluates its intrathecal administration for the prevention of EVD occlusion. Not all therapies are appropriate for all patients, and customizing strategies is often the right way to get the best result. Methods: This retrospective study analyzed 20 patients with EVDs receiving intrathecal uPA. The patients had a mean age of 56.4 years, with 95% presenting with hydrocephalus and 80% presenting with intraventricular hemorrhage. uPA dosages varied (25,000–100,000 IU), with an average of 3.9 doses per patient. Results: IVF effectively maintained EVD patency in 95% of cases. One patient experienced asymptomatic bleeding, while four (20%) developed post-treatment infections, the development of which was potentially influenced by the prolonged duration of EVD retention (>21 days). Analysis of Graeb scores showed faster clot resolution with early uPA administration. A higher initial Graeb score correlated with increased total uPA load but not with mortality or discharge outcomes. Although infection rates were slightly higher than in CLEAR III, multiple confounding factors, including duration of EVD retention and bilateral placement, were present. Conclusions: This study supports the feasibility and safety of intrathecal uPA administration for management of EVD occlusion in certain contexts. The appropriate choice in the context of ‘personalized medicine’ must necessarily consider the risk–benefit ratio. Full article

Background/Objectives: Hypertension is strongly linked to changes in vascular function and lipid metabolism. This study aimed to examine the relationship between lipid profiles, various metabolic biomarkers, and pulse wave analysis in patients with hypertension. Methods: A group of 66 hypertensive patients, aged 64 ± 10 years, participated in pulse wave analysis utilizing an oscillometric device. Multiple lipid serum biomarkers were assessed, such as total cholesterol (TC), triglycerides (TG), and non-HDL cholesterol (non-HDL). Lipid balance index (LBI) was determined by considering TG, LDL, HDL levels, and lipid-lowering medications. Results: Notable correlations were observed for SBP, DBP, and early vascular aging (EVA) with lipid biomarkers. In addition to serum lipids, metabolic syndrome, insulin resistance, and non-alcoholic fatty liver disease (NAFLD) were significantly linked to pulse wave analysis variables. Multiple regression analysis showed that only TC continued to have a significant association with DBP. Conclusions: Total cholesterol, triglycerides, non-HDL cholesterol, and lipid balance index provide information about systolic and diastolic blood pressure, as well as early vascular aging in hypertensive patients. LBI offers valuable vascular insights in hypertensive individuals with cardiovascular risk factors, early vascular aging, insulin resistance, and NAFLD. The connection between metabolic biomarkers and pulse wave measurements in individuals with hypertension offers a comprehensive method for the early identification of vascular injury and could enhance the prediction of major cardiovascular events.

Youth sport participation provides undeniable physical, emotional, and social benefits. However, the current landscape of pediatric athletics has shifted toward early sports specialization (ESS), year-round training, and heightened competitive pressures. This has led to an increased prevalence of overuse-related traumatic injuries in adolescent patients, as well as increased risk of worsening mental health due to burnout, depression, suicide, and general psychological distress. There are numerous innovations and solutions aimed at addressing the increased risk of injury associated with current sporting trends, such as neuromuscular training programs, delayed specialization, promotion of free play, and pediatric specific surgical techniques mindful of future growth, such as those seen for anterior cruciate ligament reconstruction (ACL-R). However, the social factors associated with an injury remain problematic and are not adequately addressed; these include social isolation, depression, anxiety, and academic decline. Sport psychology is a promising solution to address many risk factors associated with poor performance, address the challenges associated with injury, and increase return-to-play in adolescent sports medicine. Integrating sport psychology into pediatric sports medicine offers the ability to directly address the emotional and cognitive demands of injury and recovery. Emphasizing mental health support and redefining success in youth sports—prioritizing enjoyment, personal growth, and long-term health over scholarships and professional aspirations—are key steps in preserving the overall benefits of pediatric sport participation. Yet sport psychology remains often underutilized and has been slow to gain traction, particularly in youth sports. This editorial serves to highlight the current state of mental health advocacy in pediatric sports medicine and how sport psychology can help young athletes manage the mental stress of high-performance athletics and mitigate the detrimental effect of injury and delayed return to sport.

Intraventricular hemorrhage (IVH) is a common complication encountered in extremely-low-birth-weight (ELBW) and very-low-birth-weight (VLBW) premature babies. The neurologic outcome of these patients is influenced by the magnitude of the hemorrhagic process that damages the involved anatomic structures but also by the impaired circulation of cerebrospinal fluid (CSF) through the ventricular system, leading to posthemorrhagic ventriculomegaly (PHVM). Cranial ultrasound (CUS) performed by neonatologists (point-of-care ultrasound—POCUS) facilitates the early diagnosis of IVH and PHVM and can objectively quantify structural alterations. Our aim was to identify the best sonographic criteria to follow-up with ventricular dilatation and predict the need for neurosurgery and neurologic deterioration. We performed a literature review in search of the most relevant ventricular measurements considered by neurosurgeons, neonatologists, and pediatric neurologists to reflect the risk of white matter injury and high intracranial pressure (HIP), thus anticipating neurologic developmental impairment (NDI). The tridimensional picture of ventricular dilatation is best captured if more than one index (ventricular index and anterior horn width) or ratio (Evans ratio, fronto-occipital horn ratio, and fronto-temporal horn ratio) is used. Conclusions: If performed using the correct protocol, serially and comprehensively, CUS is an indispensable tool for the diagnosis and follow-up of neurologic complications of preterm babies, and it can make a difference in guiding adequate intervention and improving long-term developmental outcomes.

Caffeine is a weak, nonselective adenosine receptor antagonist. At low-to-moderate doses, caffeine has a stimulating effect; however, at higher doses, it can act as a depressant. It can function both as a neuroprotectant and a neurotoxin. In experimental Traumatic Brain Injury (TBI), administration of this psychoactive drug has been associated with beneficial or detrimental effects, depending on the dose, model, and timing. In a healthy brain, caffeine can enhance alertness and promote wakefulness. However, its consumption during late adolescence and early adulthood disrupts normal pruning processes in the context of repetitive moderate TBI (mTBI), leading to changes in dendritic spine morphology, resulting in neurological and behavioral impairments. Caffeine can potentially reduce TBI-associated intracranial pressure, oxidative stress, lipid peroxidation, cytotoxic edema, inflammation, and apoptosis. It can enhance alertness and reduce mental fatigue, which is critical for the cognitive rehabilitation of TBI patients. Additionally, caffeine positively affects immune cells and aids recovery post-TBI. Antagonizing adenosine receptors involved in controlling synaptic transmission, synaptic plasticity, and synapse toxicity can improve cognitive function. Conversely, studies have also shown that caffeine consumers report significantly higher somatic discomfort compared to non-consumers. This review aims to explore various studies and thoroughly examine the positive and negative roles of caffeine in TBI. Full article

Flatfoot, or pes planus, is a condition where the foot’s arch collapses, leading to complications such as pain, gait abnormalities, and an increased risk of injury. Accurate and early diagnosis is critical for effective treatment. Traditional diagnostic methods, including radiographic imaging, footprint analysis, and plantar pressure measurement, often require specialized equipment and are subjective. This study proposes a novel diagnostic device that captures 2D plantar foot images to calculate key morphological indices, including the Staheli Index, Clark’s Angle, and Chippaux–Smirak Index, for flatfoot detection. The device, designed with off-the-shelf components, includes a transparent toughened glass platform and LED illumination to capture images using web cameras. A Python-based application was developed for image acquisition, segmentation, and stitching. The device was tested on 55 participants aged 18–28, and the extracted morphological indices were validated against established thresholds for flatfoot diagnosis. The results showed that the Staheli Index, Chippaux–Smirak Index, and Clark’s Angle reliably detected flatfoot in participants. The study highlights the potential of this device for non-invasive, accurate, and rapid flatfoot diagnosis. Future advancements in deep learning could enhance its capabilities, making it a valuable tool for proactive healthcare in foot deformity detection. Full article

Postoperative infection following anterior cervical spine surgery, particularly when complicated by esophageal injury, is a rare but serious condition associated with significant morbidity and mortality. This review elucidates the complex interplay between postoperative infection and esophageal injury. We systematically analyzed studies from 2000 to 2025 using PubMed, Scopus, and Web of Science, focusing on infection, esophageal injury, surgical outcomes, and management strategies, with emphasis on recent advances in diagnostics, surgical techniques, and postoperative care. Our findings highlight the multifactorial nature of these complications and the critical role of early recognition, accurate diagnosis, and timely management. Imaging modalities such as CT, MRI, and contrast esophagography, along with flexible esophagoscopy, are indispensable in assessing injury and infection extent. Effective management requires a multidisciplinary approach integrating broad-spectrum antibiotics, surgical debridement, vascularized flap reinforcement, negative pressure wound therapy, and antibiotic-loaded cement beads. Meticulous postoperative care with prolonged antibiotics, nutritional support, and imaging follow-up is vital for optimizing outcomes. Innovative approaches, including vascularized muscle flaps and hyperbaric oxygen therapy, show promise in enhancing healing and reducing infections. Our review underscores the need for future meta-analyses to strengthen evidence and refine protocols. As surgical techniques evolve, so too must our diagnostic, surgical, and postoperative strategies to minimize complications and improve patient outcomes. Full article

Secreted protein acidic rich in cysteine (SPARC), one of the extracellular matrix proteins, is highly induced during inflammation. We investigated the pathophysiological regulation and role of SPARC in vascular inflammation in a rat model of hypertension created using deoxycorticosterone acetate (DOCA, 40 mg/kg/week, s.c.) and salt (1% in drinking water). DOCA–salt administration time-dependently increased systolic blood pressure during the 3-week treatment period, blunted endothelium-dependent vasodilation, and increased monocyte chemoattractant protein-1 (MCP-1) and lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1) expression in the aorta. SPARC expression transiently increased until week 2 in the DOCA–salt rat aorta. Interestingly, aortic SPARC levels correlated with blood pressure and the levels of MCP-1 and LOX-1 during 0–2 weeks. The AT₁ receptor blocker, losartan, suppressed the overexpression of SPARC, and in vitro treatment with angiotensin II enhanced the production of SPARC in rat aortic endothelial cells. Exposure to recombinant SPARC protein induced overexpression of MCP-1 and LOX-1 mRNA in endothelial cells. Bioactive forms of a disintegrin and metalloproteinase with thrombospondin type 1 motif (ADAMTS1), excessive activation of which contributes to pathological states and overexpression of which is reported to be induced by SPARC, were increased in the DOCA–salt rat aorta. These results suggest that SPARC is induced by the vascular renin–angiotensin system and causes inflammation in the early stages of hypertensive vascular injury, and that activation of ADAMTS1 might be related to the proinflammatory effects of SPARC.

Background: The prevention of pressure injuries depends on the early and correct assessment of at-risk patients. Since risk assessment involves more than using a risk factor instrument, we intend to map the existing recommendations and statements of good practice for pressure injury risk assessment in adults admitted to intensive care units, as well as identify the strengths of the evidence and recommendations in the literature. Methods: This study is a scoping review, guided by the Joanna Briggs Institute framework. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews was adopted as a guide for writing this study. Results: Searches were carried out in six databases, resulting in 794 studies, of which 15 were included. The recommendations and statements of good practice were grouped into five categories: risk assessment instruments, skin assessment, medical device surveillance, other alternatives to risk assessment, and implementing best practices in clinical settings. The strengths of the evidence and recommendations were identified when available in the literature. Conclusions: The mapping showed that the evidence is sufficient to indicate recommendations and statements of good practice for the risk assessment of pressure injuries in adults admitted to intensive care units. The protocol was retrospectively registered in the Open Science Framework on the 4th of August of 2023. Full article

In the construction of deep foundation pits, early warning measures are essential to reduce construction risks and prevent personnel injuries. In underground structure and pressure analysis, soil layer and support structure data are indispensable. Therefore, soil layer reconstruction serves as a critical step, while sparse borehole data limit the accuracy of traditional reconstruction methods. This paper proposes a machine learning-based soil layer reconstruction method to address this issue. First, various types of borehole and soil layer data are generated by simulating the formation process of Earth’s soil layers, thereby providing sufficient training data. Subsequently, a coding algorithm is designed to extract soil layer features as inputs for the convolutional neural network. Finally, 3D meshing is performed on the soil layer generated from real boreholes, and soil model rendering is achieved through a voxel clustering algorithm. The algorithm achieved an accuracy rate of over 90% in tests and demonstrated excellent robustness. By applying this algorithm, we successfully reconstructed the soil layers at a typical foundation pit site in a Chinese city, validating its effectiveness in real-world scenarios and its potential for large-scale engineering applications.

Background and Objectives: Pediatric patients can acquire scars from both accidental injury and surgical procedures. While scars cannot be avoided if a full-thickness injury occurs, scar visibility may be minimized through a variety of approaches. In this narrative review, we evaluate the current evidence and propose an algorithm for scar management in pediatric patients. Materials and Methods: A review of the literature was performed for scar management techniques for pediatric patients. Management modalities based on the type of scar and dosing, treatment regimen, and safety profiles are described in this article and used to create a scar management algorithm. Results: The initial step to scar management in the pediatric population involves ensuring minimal wound tension, which can be achieved through making the incision along relaxed skin tension lines, and early, minimal tension wound closure. Subsequent treatments to optimize scar care should begin 2–3 weeks following wound closure and involve the application of silicone gel or sheets and scar massaging. When topical products are insufficient, laser therapy can be utilized for the management of immature erythematous or thick scars. When mature, pathological scars form such as atrophic scars, hyperpigmentation, hypertrophic scars, or keloids, a combination of modalities is recommended. These modalities vary by scar type and include retinoids and dermabrasion for atrophic scars; retinoids, hydroquinone, and laser therapy for hyperpigmentation; and pressure therapy, corticosteroids, and laser therapy for hypertrophic scars and keloids. When mature, pathological scars persist following 12 months of non-invasive therapies, surgical excision should be considered. Conclusions: Several treatment options are available to manage scars in the pediatric population depending on scar type. Full article

Background: Disorders of Consciousness (DoC) following acute brain injuries, such as intracerebral hemorrhage, present significant clinical challenges in intensive care and rehabilitation settings. Early multidisciplinary interventions, including physiatric care, are critical in optimizing recovery trajectories. However, evidence regarding the timing and intensity of rehabilitation interventions remains limited. This case report highlights the role of physiatrists in managing a critically ill patient with a DoC in an Intensive Care Unit (ICU), focusing on early rehabilitation strategies and individualized care planning. Case presentation: A 63-year-old male with a history of hypertension and cardiac disease presented with a left hemispheric hemorrhage and quadriventricular intraventricular hemorrhage. The patient was admitted to the ICU in a comatose state (Glasgow Coma Scale [GCS] 5). Initial physiatric evaluation revealed a critical condition precluding immediate initiation of an Individual Rehabilitation Project (IRP). Over subsequent weeks, clinical improvements were observed, including an increased GCS and Coma Recovery Scale-Revised (CRS-R) score. A tailored IRP was implemented, emphasizing passive mobilization to prevent complications such as muscle atrophy, joint contractures, and pressure ulcers. The patient demonstrated gradual progress, transitioning to a Minimally Conscious State (MCS) and achieving improved joint mobility and reduced peripheral edema. Discussion and Conclusions: This case underscores the pivotal role of physiatrists in ICU settings, particularly for patients with DoC. Early physiatric interventions, even in critically ill patients, can prevent secondary complications and facilitate functional recovery. Close collaboration with ICU teams and infectious disease specialists ensured the safe implementation of rehabilitation strategies despite the patient’s severe condition. The observed clinical improvements highlight the potential benefits of early mobilization and individualized care plans, both in terms of survival (quoad vitam) and quality of life (quoad valetudinem). This report emphasizes the need for further research to refine rehabilitation practices for patients with DoC, bridging gaps between acute care and neurorehabilitation. Full article

Background and Objectives: Abdominal compartment syndrome (ACS) is a severe clinical condition caused by intra-abdominal hypertension (IAH), often observed in surgical and trauma patients. However, ACS can also develop in non-surgical patients with massive ascites, leading to acute kidney injury (AKI) due to renal hypoperfusion. This study investigates the association between intra-abdominal pressure (IAP) changes, renal biomarkers, and mortality in patients with ACS-related AKI. Materials and Methods: A prospective cohort study was conducted on 24 hospitalized patients with ascites due to malignancy, cirrhosis, or heart failure. IAP was measured via the trans-vesical method on the first and seventh days of hospitalization. Serum and urinary biomarkers, including kidney injury molecule-1 (KIM-1), neutrophil gelatinase-associated lipocalin (NGAL), and interleukin-6 (IL-6), were assessed for their correlation with IAP changes. The primary outcome was in-hospital mortality, and the secondary outcomes included AKI progression and the effect of paracentesis on IAP reduction. Results: The overall in-hospital mortality rate was 50%. Patients who survived had significantly lower IAP on the seventh day compared to those who died (14.9 ± 3.5 mmHg vs. 20.2 ± 5.6 mmHg, p = 0.01). A 25% reduction in IAP was associated with improved kidney function and increased survival (p < 0.001). Urinary KIM-1 and serum NGAL levels showed a moderate correlation with IAP (r = 0.55, p = 0.02 and r = 0.61, p = 0.018, respectively), while IL-6 levels were significantly higher in non-survivors (p = 0.03). Paracentesis was associated with improved survival outcomes (p = 0.04). Conclusions: ACS is a critical but often overlooked cause of AKI in non-surgical patients with massive ascites. Lowering IAP significantly improves renal function and reduces mortality. Urinary KIM-1 and serum NGAL may serve as useful biomarkers for monitoring IAP changes. The early identification and management of IAH through timely interventions such as paracentesis and volume control strategies could improve patient outcomes. Full article
