Background: Patient-specific instrumentation (PSI) in total knee arthroplasty represents an increasingly relevant component of personalized surgical planning. As nearly half of orthopedic patients search online for medical information before or after clinical consultation, the quality, accuracy, and readability of publicly available digital resources directly influence patient expectations, shared decision-making, and rehabilitation engagement. This study assessed the content, quality, and readability of online information about PSI in TKA.

Methods: Google searches using four predefined PSI-related terms were conducted on 6 March 2025. After applying exclusion criteria, 71 websites were included for evaluation. Websites were categorized as academic or non-academic and analyzed for authorship, reporting of advantages and disadvantages, inaccurate assertions, use of peer-reviewed references, multimedia content, and mention of specific PSI platforms. Website quality was assessed using validated quality evaluation tools (QUEST and JAMA criteria), and readability was evaluated using established readability indices (SMOG, FKGL, and FRE).

Results: Academic websites demonstrated significantly higher quality than non-academic sources based on QUEST (25.4 vs. 9.8; p < 0.001) and JAMA criteria (3.7 vs. 1.7; p < 0.001). Disadvantages of PSI were reported in 69.1% of academic sites versus 12.5% of non-academic sites (p < 0.001). Inaccurate claims occurred in 31.3% of non-academic sites but were absent in academic sources (p < 0.001). Peer-reviewed references were present in 81.8% of academic websites and only 12.5% of non-academic sites (p < 0.001). Readability was uniformly poor across all websites, with no significant group differences (mean SMOG 13.5; mean FKGL 11.8; mean FRE 32.4).

Conclusions: Online information about PSI in total knee arthroplasty varies widely in transparency and accuracy, with non-academic websites frequently omitting risks or presenting misleading claims. Given the role of individualized implant planning, accessible and evidence-based digital content is essential to support personalized patient education and shared decision-making. Because limited readability restricts patient comprehension and informed participation in personalized orthopedic care, improving the clarity and accessibility of digital patient resources is essential.

Background/Objectives: Cement augmentation of cephalomedullary head elements can improve the purchase of osteoporotic bone; however, it does not eliminate the need for accurate implant positioning or the preservation of sliding. We report the case of an 87-year-old woman who underwent intramedullary nailing with a cement-augmented helical blade for intertrochanteric fracture. Methods: This is a single-patient case report. Calibrated radiographic measurements-tip-apex distance (TAD), calcar-referenced TAD (CalTAD), neck-shaft angle (NSA), and telescoping-were obtained immediately postoperatively and at 4, 7, 12, and 15 months. CT was performed at postoperative week 1 and at failure, and MRI was performed for clinical deterioration. In addition, a targeted narrative review summarizes the evidence on the head-element position, sliding behavior, reduction alignment, and augmentation. Results: Immediate postoperative indices were within the accepted targets: TAD 22.6 mm, CalTAD 22.8 mm, NSA 134°, with the head element inferior on the anteroposterior view and central on the lateral view. Rehabilitation proceeded with full weight bearing as tolerated. Early telescoping was minimal (3.8-3.9 mm). Between 7 and 15 months, progressive varus with shortening of TAD/CalTAD and little additional telescoping was observed, radiographically consistent with relative proximal migration of the head-cement complex and a cleavage plane along the inferior cement mantle, culminating in a subcapital femoral neck fracture with the implant in situ. Emphasis should be placed on accurate implant positioning and preservation of sliding capacity, because cement augmentation alone may not prevent mechanical failure when the implant position or load transfer is suboptimal. Conclusions: Cement augmentation stiffens the interface and reduces micromotion but does not neutralize malposition-induced stresses. Accurate positioning, preservation of sliding, and timely conversion when sliding fails to progress are advisable; these findings are hypothesis-generating from a single case. We propose a position- and sliding-based decision guide to support clinical decision-making; its usefulness remains to be validated in larger studies.

Background/Objectives: Unusual-site venous thrombosis (USVT) lacks robust evidence guiding anticoagulant selection between vitamin K antagonists (VKAs) and direct oral anticoagulants (DOACs). This study aimed to evaluate recanalization, recurrence, and major bleeding outcomes in real-world USVT patients and to replicate these findings through a validated digital twin model with Monte Carlo simulation. Methods: We conducted a retrospective study of 90 USVT patients (72% VKAs, 28% DOACs). A conditional generative adversarial network was used to generate digital twins matched on age, sex, thrombosis site, and malignancy. Logistic regression was applied to estimate treatment-specific outcome probabilities for recanalization, recurrence, and major bleeding. A nested stochastic simulation framework simulated 500 iterations across clinical scenarios, including increased DOAC use, cancer prevalence, cerebral vein thrombosis proportion, and optimized VKA control. Results: The mean age was 67.5 years, and 54.4% were female. 61.1% of splanchnic vein thrombosis, 36.7% of upper extremity deep vein thrombosis, and 2.2% of cerebral vein thrombosis were included. In the real cohort, complete recanalization occurred in 40.0% of patients with DOACs and 36.0% with VKAs. Recurrence was 8.0% with DOACs and 7.7% with VKAs, and major bleeding occurred in 8.0% and 10.8% of cases, respectively. All-cause mortality was 20% in DOAC-treated patients and 60% in those receiving VKAs. Digital Twin-based predictions replicated these results (recanalization 40.3% versus 38.0%; recurrence 10.9% versus 8.6%; bleeding 7.6% versus 9.1%). Simulated scenarios preserved the directionality effect, with the most significant differences observed in high-cerebral vein thrombosis and cancer-enriched patients. Conclusions: DOACs showed comparable efficacy and slightly lower bleeding risk than VKAs in USVT. Digital twin and Monte Carlo modeling provided robust, reproducible simulations of treatment effects under varying clinical conditions. Separating empirical and simulation-based findings, the digital twin supported the internal consistency of real-world observations and demonstrated the potential of in silico modeling as a complementary tool in rare thrombotic diseases.

Introduction: Total hip replacements and total knee replacements are among the most frequently performed operations worldwide, and the demand for such procedures is ever-growing. It is essential to focus on preventable medical complications that can arise from these procedures, specifically postoperative hyponatraemia. Postoperative hyponatraemia has an incidence of 20-40% in total hip and knee replacement patient cohorts. Even mild postoperative hyponatraemia is clinically relevant, as it is associated with cognitive impairment and gait disturbance and may undermine the aims of enhanced recovery protocols. Severe postoperative hyponatraemia can lead to seizures, coma, intensive care admission, and death. Although uncommon, the high volume of patients treated in busy orthopaedic centres means such cases will inevitably be encountered. This narrative review summarises the current evidence on incidence, risk factors and consequences of postoperative hyponatraemia in total hip and knee replacement populations. Methods: A literature review was performed through the EBSCO and PubMed databases to identify relevant studies. Key search terms included were "hyponatraemia", "total hip replacement", and "total knee replacement". Results: The incidence of postoperative hyponatraemia is largely between 20% and 40%; however, there are some outliers to this. Multiple risk factors have been identified through observational studies, including age, preoperative hyponatraemia, female sex and certain medications, which signal a need for a risk stratification strategy that can assist in preoperative assessment and the early identification of patients at higher risk of developing postoperative hyponatraemia. Evidence is scarce regarding interventional studies for the prevention and management of postoperative hyponatraemia, despite multiple studies highlighting the issue. Conclusion: Future work should focus on testable, quality improvement interventions, such as automatic sodium checks on postoperative day one, weight-based oral fluid protocols, oral salt supplementation, and escalation pathways for high-risk patients. Incorporating these into enhanced recovery frameworks has the potential not only to optimise safe early discharge for the majority but also to prevent rare but significant complications.

Background: Epidemiological studies on benign epithelial salivary gland tumors are challenging due to their rarity, pathological heterogeneity, variable tumor locations, and the limited national data collection in Romania. Our study aimed at the evaluation of benign epithelial salivary gland tumors collected over fifteen years in a tertiary center, in order to characterize their demographic and histopathological profiles and to contribute to their diagnostic and therapeutic strategies. Materials and Methods: A retrospective analysis of 404 cases of benign epithelial salivary gland tumors diagnosed in "Sf. Spiridon" County Hospital, Iasi, from 2010 to 2024, has been performed. Results: The analyzed cases showed a slight female predominance (52.97%) and a mean patient age of 54.55 ± 14.207 years. Tumor frequency increased progressively with age, peaking in the sixth and seventh decades of life. The most common histological types were pleomorphic adenoma (62.62%) and Warthin tumor (29.95%), both types showing a predominant parotid gland involvement (88.51%). The recurrences were rare, being registered only in 1.58% of pleomorphic adenomas. A significant association between tumor histological type and both gender (p < 0.001) and age group (p < 0.001) was registered, while no significant correlation between gender and age group (p = 0.288) or between tumor location and gender or age group (p = 0.382; p = 0.383) was found. Conclusions: The frequency of pleomorphic adenoma is increasing, showing an age-related distribution and parotid gland propensity. Key morphological features in each histological type support a better preoperative stratification, a more confident margin assessment, and an individualized extent of excision with function preservation.

Background: Urine cytology is a highly effective, straightforward, and cost-efficient diagnostic tool for identifying neoplastic and non-neoplastic changes in the bladder, ureter, and renal pelvis. The aim of this study is to demonstrate the high sensitivity and specificity of urine cytology in detecting a wide range of urothelial lesions, including metastatic involvement.

Material and methods: Urine cytology was performed on 9639 cases between 2000 and 2025. The samples, collected from patients, were processed at the Institute of Pathology. Cytological slides were prepared using cytocentrifugation and stained with May-Grünwald-Giemsa (MGG) and Papanicolaou stains. The cytological findings were classified according to WHO, 2004 compared with histological specimens. Additionally, selected cases underwent immunohistochemical and molecular analyses. All samples were anonymized and retrospectively analyzed following the guidelines and regulations of the local ethics committee.

Results: Of the total cases, 7051 were classified as benign, 1269 as malignant, and 88 as normal findings. Insufficient material was obtained in 336 cases. No complications were reported during sample collection or processing. The concordance with histological findings for neoplastic lesions was over 96%, with a false-negative rate of 1.84%. The diagnostic methods demonstrated a sensitivity of 90.7% and a specificity of 96.64%. Among the 6956 cases analyzed, 3139 were women (45.13%) and 3817 were men (54.87%).

Conclusions: The diagnostic value of urine cytology in representative material is relatively high in assessing both the presence or absence of malignancy and, when applicable, the tumor grade. This large 25-year single-center review demonstrates that urine cytology retains high sensitivity and specificity for the detection of urothelial malignancy, particularly high-grade disease. However, the atypical category remains a major diagnostic challenge and contributes substantially to false-positive results.

Background/Objectives: Chronic inflammation arises from self-reinforcing immune-metabolic circuits encompassing pattern-recognition signaling, inflammasome activation, cytokine networks, immunometabolic reprogramming, barrier-microbiome disruption, cellular senescence, and neuro-immune-endocrine crosstalk. This review synthesizes these mechanistic axes across diseases and introduces an operational endotype-to-care framework designed to translate mechanistic insights into precision-based, scalable, and equitable interventions. Methods: A narrative, mechanism-focused review was performed, integrating recent literature on immune-metabolic circuits, including pattern-recognition receptors, inflammasome pathways, cytokine modules, metabolic reprogramming, barrier-microbiome dynamics, senescence, and neuro-immune-endocrine signaling. Validated, low-cost screening biomarkers (hs-CRP, NLR, fibrinogen) were mapped to phenotype-guided endotyping panels and corresponding therapeutic modules, with explicit monitoring targets. Results: We present a stepwise, pragmatic pathway progressing from broad inflammatory screening to phenotype-specific endotyping (e.g., IL-6/TNF for metaflammation; ISG/IFN for autoimmunity; IL-23/17 for neutrophilic disease; IL-1β/NLRP3 or urate for crystal-driven inflammation; permeability markers for barrier-dysbiosis). Each module is paired with targeted interventions and prespecified treat-to-target outcomes: for example, achieving a reduction in hs-CRP (e.g., ~40%) within 8-12 weeks is used here as a pragmatic operational benchmark rather than a validated clinical threshold. Where feasible, cytokine and multi-omic panels further refine classification and prognostication. A tiered implementation model (essential, expanded, comprehensive) ensures adaptability and equity across clinical resource levels. Conclusions: Distinct from prior narrative reviews, this framework defines numeric triage thresholds, minimal endotype panels, and objective monitoring criteria that make chronic inflammation management operationalizable in real-world settings. It embeds principles of precision, equity, and stewardship, supporting iterative, evidence-driven implementation across diverse healthcare environments.

Background: The scope of practice for pharmacists in the United States (US) is expanding rapidly, with the majority of states allowing pharmacists to prescribe to some degree. Doctor of Pharmacy (PharmD) programs are required to include medication prescribing effective 1 July 2025, ensuring program alignment with modern pharmacy practice. Objective: This study aimed to characterize student pharmacists' beliefs about education on prescribing in the US PharmD program. Methods: Focus group discussions (FGDs) were conducted with student pharmacists enrolled in the PharmD curriculum at two different universities in the US. The conceptualization and data collection, guided by Self-Determination Theory, occurred over three months during the 2024 Fall semester. Data analysis was performed using thematic analysis, and themes were identified through inductive and deductive coding. Results: Twenty-two student pharmacists participated in three FGDs. Thematic analysis revealed two major themes: (1) essential role of didactic education in the prescribing process and (2) enhancing student preparedness to prescribe through experiential training. These themes uncover student pharmacists' beliefs that prescribing education is vitally important to the didactic and experiential curriculum, highlighting the need to take a comprehensive approach to incorporate these topics into the PharmD program. Conclusions: Teaching medication prescribing in the PharmD didactic curriculum using a state's scope of practice as a framework for its delivery, with reinforcement in their experiential training, to ensure pharmacy students are practice-ready, may be a preferred approach for delivery. This area remains ripe for further study to determine an evidence-based approach to teaching medication prescribing to pharmacy students.

Background: Chronic maxillary sinusitis is most often linked to dental, allergic, or anatomical etiologies, with foreign body-induced forms remaining rare. This case report describes a unique occurrence of chronic maxillary sinusitis resulting from misplaced hyaluronic filler due to a facial esthetic procedure. Case presentation: A 60-year-old woman experienced right-sided maxillary sinusitis symptoms for three years after hyaluronic filler injections. Multi-slice computed tomography showed total sinus opacification, a vermicular foreign body, and a small anterior wall perforation. The patient underwent Caldwell-Luc surgery for foreign body removal and mucosal excision, followed by histopathological analysis. Results: The procedure was successful, with complete extraction of the foreign body compatible with hyaluronic filler. Postoperative recovery was uneventful, and symptoms resolved. This rare complication likely resulted from accidental filler penetration into the maxillary sinus during the injection. Conclusions: To the best of our knowledge, after a detailed search of the available literature, this is the first reported case of chronic maxillary sinusitis caused by material that is compatible with misplaced hyaluronic filler. It stresses the critical need to minimize serious complications in the facial esthetic procedures through detailed anatomical knowledge, technical skill, and a strict credentialing protocol of practitioners. Further awareness and regulations could improve patient safety.

Background: Surgical site infections (SSIs) are common postoperative complications. Data on SSIs following breast surgery in Saudi Arabia are limited because these procedures are not included in the national SSI surveillance system. This study determined the SSI incidence rate, identified associated risk factors, and described the microbiological profiles of patients undergoing breast surgery at two tertiary hospitals in Saudi Arabia. Methods: This bicentric retrospective case-control study analyzed 1841 breast surgeries performed at two tertiary hospitals between July 2021 and July 2024. Demographic, surgical, and microbiological data were extracted from electronic medical records. SSIs were defined according to National Healthcare Safety Network criteria. Descriptive statistics summarized patient and surgical characteristics and SSI rates. A matched case-control analysis (1:4 ratio based on age and hospital site) included 172 patients. Multivariable logistic regression was used to identify predictors of SSI. Results: The cumulative SSI incidence was 2.4%, and most infections occurred within 30 days of surgery (69%). Gram-negative organisms were predominant in microbiologically positive cases (53.6%), mainly Klebsiella pneumoniae and Pseudomonas aeruginosa, whereas Staphylococcus aureus (including MRSA) accounted for 25%. Immunocompromised status (OR 3.32, 95% CI 1.35-8.14) and surgical drain use (OR 4.07, 95% CI 1.68-9.87) were independently associated with SSI. Conclusions: The incidence of SSIs after breast surgery in Saudi Arabia was relatively low. The predominance of Gram-negative pathogens and the identification of immunocompromised status and surgical drain use as major risk factors highlight opportunities for targeted infection prevention strategies. Further studies should validate these findings in larger and more diverse populations and healthcare settings.
