Endoscopic Treatment of Gastric Bezoars: A Report of Three Cases

Bezoars, including phytobezoars, trichobezoars, and pharmacobezoars, are accumulations of undigested substances in the gastrointestinal tract. We report three cases of gastric bezoars. Case 1: An 86-year-old woman presented with a one-month history of abdominal pain and vomiting. Esophagogastroduodenoscopy revealed gastric bezoars; consumption of 2 L of cola daily for 2 weeks resulted in complete disappearance of the bezoars. Case 2: An asymptomatic 63-year-old woman underwent esophagogastroduodenoscopy, which revealed a gastric bezoar. Cola spraying and endoscopic lithotomy were ineffective; therefore, the patient underwent laparoscopic removal of the bezoar for management of small bowel obstruction secondary to the bezoar fragments. Case 3: A 6-year-old girl with a history of pica underwent two laparoscopic surgeries 10 months apart for recurrent trichobezoars. We report our treatment approach in three patients who presented with gastric bezoars.

Callous-unemotional traits moderate the association between inhibitory control and disruptive behavior problems.

The presence of callous-unemotional (CU) traits may not be unique to conduct disorder (CD) but also extend to oppositional defiant disorder (ODD). While a distinct neurocognitive profile characterizes CU traits, it remains unclear whether this CU-related neurocognitive profile differs between youth with CD and ODD. This study investigated whether CU traits moderate the relationship between inhibitory control and CD or ODD symptoms. We leveraged computational modeling to decompose task-based inhibitory control in a sample of 200 children (59.5% boys, 86.5% Caucasian), aged 8 to 15 years (M = 10.10, SD = 1.88), referred to an outpatient child diagnostic clinic focused on externalizing problems. Analyses examined whether CU traits moderated the relationship between inhibitory control and CD or ODD symptoms while controlling for ADHD symptoms and child demographics. The results indicated that the strength of the relationship between inhibitory control and CD and ODD symptoms varies as a function of CU traits. Specifically, CD was linked to a more cautious decision-making style when elevated CU traits were present, whereas ODD was associated with more efficient decision making. These findings suggest distinct neurocognitive profiles based on CU traits, which vary between CD and ODD. Clinically, this underscores the importance of tailoring interventions for CD-CU and ODD-CU, focusing on decision making processes rather than merely addressing impulsivity. This research contributes to a more nuanced understanding of the interaction between neurocognitive processes and disruptive behavior, with significant implications for both theoretical models and treatment approaches.

mRNA therapy: a precise and efficient approach for disease treatment

Psoriasis treatment and biologic switching: The association with clinical characteristics and laboratory biomarkers over a 13-year retrospective study.

The advent of biologics has greatly improved patient outcomes, yet some patients are compelled to switch therapies. Predicting these therapeutic failures is important; however, the factors associated with switching biologics have not been fully explored. This study examined patterns and determinants of biologics switching in psoriasis treatment retrospectively over 13 years. We focused on the association between clinical characteristics, basal laboratory data, and frequency of biologics switching. The findings revealed that elevated Psoriasis Area Severity Index scores and the presence of arthritis were observed in patients who experienced two or more treatment switches compared with those without treatment switches. Moreover, neutrophil to lymphocyte ratio was associated with higher biologics switching rates, indicating that systemic inflammation significantly impacts treatment adherence. A treatment approach, taking into account both the clinical presentation and inflammatory biomarkers, may be important for optimizing patient management in psoriasis.

Long-term photogrammetric outcomes of midface advancement in Apert syndrome: are we nearing normal?

The aesthetic goals of midface surgery in Apert syndrome are to correct the multi-planar midface deficiency and normalize facial ratios. This study characterizes the long-term photogrammetric outcomes of midface advancement in Apert syndrome. Patients with Apert syndrome who underwent midface distraction from 2000 to 2023 were retrospectively reviewed. Soft tissue measurements were applied to preoperative (T0), short-term postoperative (T1), and long-term postoperative (T2) photographs. Long-term changes were compared between subcranial and transcranial procedures, segmental and non-segmental osteotomies, and individual techniques. Frontal facial dimensions at time T2 were compared to age- and sex-matched normal controls from the NIMH-ChEFS face database. Twenty patients had postoperative follow-up of T1 = 0.6 ± 0.4 and T2 = 4.7 ± 1.1years and were compared to 40 normal controls. From time T0 to T2, middle facial third height increased (26.1 ± 3.0% to 27.8 ± 2.6%, p = 0.026), canthal tilt improved (- 7.6° ± 3.7° to - 3.9° ± 4.4°, p < 0.001), and facial convexity increased (182.9° ± 6.2° to 167.9° ± 8.6°, p < 0.001). From time T1 to T2, facial convexity flattened (159.4° ± 10.1° to 167.9° ± 8.6°, p < 0.001). Compared to controls, patients at time T2 had shorter middle facial third height (27.8 ± 2.6% vs. 32.0 ± 1.9%, p < 0.001) and reverse canthal tilt (- 3.9° ± 4.4° vs. 5.4° ± 2.6°, p < 0.001). A tailored treatment approach to the Apert midface yields varying degrees of resolution of central midfacial shortening, canthal tilt, and facial concavity at 5years postoperatively. A slight reduction in facial convexity over time, likely reflecting pseudorelapse in the setting of sagittal overcorrection, should be anticipated. Greater utilization of segmental osteotomies may bring facial third ratios and canthal tilt closer to normal morphometric values.

Strategies to Reduce Frequent Emergency Department Use among Persons Experiencing Homelessness with Mental Health Conditions: a Scoping Review.

The USA has some of the highest utilization rates of the Emergency Department (ED) worldwide, leading to increased healthcare costs, constrained resources, and fragmented care. Many of the highest ED utilizers are persons experiencing homelessness (PEH) and those with mental health conditions, with even higher use by those with comorbid social challenges. This study reviewed the literature assessing interventional approaches in the ED to minimize the burden of ED utilization by PEH with associated mental health conditions. We first conducted an informal literature review of high ED utilizers and their most common presenting symptoms. We then conducted a scoping review of articles according to the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines; we used PubMed and Web of Science databases as well as Google Scholar. We screened the titles and abstracts of studies that evaluated programs that aimed to reduce ED usage by patients with mental illness who were also experiencing homelessness. Of the 1574 titles and abstracts screened, 49 full texts were examined for eligibility. Of those, 35 articles were excluded for a final count of 14 included studies. We found that the studies fell under two main interventional categories: housing support and care management. There were various approaches to reduce ED visits from PEH with mental illness around the world. Overall, these studies found varying degrees of success in reducing ED visits for both housing intervention and care management strategies. Comparison of these studies reveals that the success of related strategies like housing support often have different outcomes which can be attributed to the differences between the populations studied, previously available community resources, and other psychosocial factors affecting study participants. Overall, the most successful studies found that a tailored approach that addresses the unique needs of participants had the greatest impact on reducing ED visits and hospitalizations. Further research is needed to determine the best strategies for specific populations and how to promote health equity among PEH with associated mental health conditions.

The influence of patient sex on pulmonary embolism evaluation, treatment modality, and outcomes.

Pulmonary embolism (PE) is the third-leading cause of cardiovascular mortality, accounting for 100,000 deaths per year in the United States. Although sex-based disparities have previously been described in this population, it is unclear if these differences have persisted with the expansion of PE evaluation and treatment approaches. The purpose of this study is to investigate sex-based differences in the evaluation, management, and outcomes of patients with acute PE. We performed a retrospective analysis of patients enrolled in the national Pulmonary Embolism Response Team (PERT) Consortium database between October 2015 and October 2022. We evaluated patient demographics, clinical characteristics, diagnostic imaging performed, treatment at several phases of care (pre-PERT, PERT recommendations, and post-PERT), and clinical outcomes. A total of 5722 patients with acute PE (2838 [49.6%] women) from 35 centers were included. There were no differences in PE risk category between male and female patients. Women were less likely to undergo echocardiography (76.9% vs 73.8%) and more likely to receive no anticoagulation prior to PERT evaluation (35.5% vs 32.9%). PERT teams were more likely to recommend catheter-based interventions for men (26.6% vs 23.1%), and men were more likely to undergo these procedures (21.9% vs 19.3%). In a multivariable analysis, female sex was a predictor of in-hospital mortality (OR 1.53, 95% CI 1.06 to 2.21). In this analysis, we identified sex-based differences in the evaluation and management of patients presenting with acute PE. Subsequently, women presenting with acute PE were at higher risk of in-hospital mortality.

Efficient Encapsulation of β-Lapachone into Self-Immolative Polymer Nanoparticles for Cyclic Amplification of Intracellular Reactive Oxygen Species Stress.

The selective upregulation of intracellular oxidative stress in cancer cells presents a promising approach for effective cancer treatment. In this study, we report the integration of enzyme catalytic amplification and chemical amplification reactions in β-lapachone (Lap)-loaded micellar nanoparticles (NPs), which are self-assembled from reactive oxygen species (ROS)-responsive self-immolative polymers (SIPs). This integration enables cyclic amplification of intracellular oxidative stress in cancer cells. Specifically, we have developed ROS-responsive SIPs with phenylboronic ester triggering motifs and hexafluoroisopropanol moieties in the side chains, significantly enhancing Lap loading efficiency (98%) and loading capacity (33%) through multiple noncovalent interactions. Upon ROS activation in tumor cells, the Lap-loaded micellar NPs disassemble, releasing Lap and generating additional ROS via enzyme catalytic amplification. This process elevates intracellular oxidative stress and triggers polymer depolymerization in a positive feedback loop. Furthermore, the degradation of SIPs via chemical amplification produces azaquinone methide intermediates, which consume intracellular thiol-related substrates, disrupt intracellular redox hemostasis, further intensify oxidative stress, and promote cancer cell apoptosis. This work introduces a strategy to enhance intracellular oxidative stress by combining enzymatic and chemical amplification reactions, providing a potential pathway for the development of highly efficient anticancer agents.

Synergistic chemotherapy and photothermal therapy of lung cancer using MoS2 nanosheets co-loaded with silybin and doxorubicin

The active ingredient in traditional Chinese medicine, silybin (SBN), is known to inhibit the proliferation of cancer cells and synergistically enhance the anticancer effects of the chemotherapy drug doxorubicin (DOX). However, the combination of SBN and DOX faces challenges such as a lack of targeting, short half-lives, different administration routes, and pharmacokinetic processes, which prevent the drug combination from effectively targeting tumors and diminish their synergistic potential, thereby limiting their in vivo antitumor effects. In response, this study proposes the development of a novel nanocarrier system based on molybdenum disulfide (MoS₂) modified with polyethylene glycol (PEG) and sialic acid (SA) to co-deliver SBN and DOX. This system is designed to trigger the release of the drugs in response to dual stimuli of pH and near-infrared light, increasing the intracellular concentration of the drugs and enhancing their synergistic interaction. The MoS₂-LPN-SBN/DOX nanosystem circulates within the body and specifically accumulates at tumor sites due to the enhanced permeability and retention (EPR) effect and SA-mediated active targeting. Upon exposure to near-infrared light, the system provides combined chemo- and photothermal therapy, leading to significant tumor suppression. This research offers a new approach and strategy for the clinical treatment of lung cancer, suggesting a promising pathway for enhancing the efficacy of traditional therapies.

Orally Deliverable Microalgal-Based Carrier with Selenium Nanozymes for Alleviation of Inflammatory Bowel Disease.

Excessive reactive oxygen species (ROS) is a hallmark of both the onset and progression of inflammatory bowel disease (IBD), where a continuous cycle of ROS and inflammation drives the progression of diseases. The design of oral antioxidant nanoenzymes for scavenging ROS has emerged as a promising strategy to intervene in IBD. However, the practical application of these nanoenzymes is limited due to their single catalytical property and significantly impacted by substantial leakage in the upper gastrointestinal tract. This study introduces a novel oral delivery system, SP@CS-SeNPs, combining natural microalgae Spirulina platensis (SP), which possesses superoxide dismutase (SOD)-like activity, with chitosan-functionalized selenium nanoparticles (CS-SeNPs) that exhibit catalase-like activity. The SP@CS-SeNPs system leverages the dual catalytic capabilities of these components to initiate a cascade reaction that first converts superoxide anion radicals (O2•-) into hydrogen peroxide (H2O2), and then catalyzes the decomposition of H2O2 into water and oxygen. This system not only utilizes the resistance of the microalgae carrier to gastric acid and its efficient capture by intestinal villi, thereby enhancing intestinal distribution and retention but also demonstrates significant anti-inflammatory effects and effective repair of the damaged intestinal barrier in a colitis mice model. These results demonstrate that this oral delivery system successfully combines the features of microalgae and nanozymes, exhibits excellent biocompatibility, and offers a novel approach for antioxidant nanozyme intervention in IBD.

In vitro Chondrogenic Induction Promotes the Expression Level of IL-10 via the TGF-β/SMAD and Canonical Wnt/β-catenin Signaling Pathways in Exosomes Secreted by Human Adipose Tissue-derived Mesenchymal Stem Cells.

Current treatment approaches cannot exactly regenerate cartilage tissue. Regarding some problems encountered with cell therapy, exosomes are advantageous because of their "cell-free" nature. This study examines the relationship between IL-10 and TGF-β and Canonical Wnt/β-catenin signal pathways in human adipose tissue-derived MSCs exosomes (hAT-MSCs-Exos) after in vitro chondrogenic differentiation. Human adipose tissue-derived mesenchymal stem cells (hAT-MSCs) and, as a control group, human fetal chondroblast cells (hfCCs) were differentiated chondrogenically in vitro. Exosome isolation and characterization analyses were performed. Chondrogenic differentiation was shown by Alcian Blue and Safranin O stainings. The expression levels of IL-10, TGF-β/SMAD signaling pathway genes, and Canonical Wnt/β-catenin signaling pathway genes, which play an essential role in chondrogenesis, were analyzed by RT-qPCR. Conditioned media cytokine levels were measured by using the TGF-β and IL-10 ELISA kits. IL-10 expression was upregulated in both chondrogenic differentiated hAT-MSC-Exos (dhAT-MSC-Exos) (p < 0.0001). In the TGF-β signaling pathway, TGF-β (p < 0.0001), SMAD2 (p < 0.0001), SMAD4 (p < 0.001), ACAN (p < 0.0001), SOX9 (p < 0.05) and COL1A2 (p < 0.0001) expressions were upregulated in dhAT-MSC-Exos. SMAD3 expression was upregulated in non-differentiated hAT-MSC-Exos. In the Canonical Wnt/β-catenin signaling pathway, WNT (p < 0.0001) and CTNNB1(p < 0.0001) expressions were upregulated in dhAT-MSC-Exos. AXIN (p < 0.0001) expression was upregulated in non-differentiated hAT-MSC-Exos. TGF-β and IL-10 levels were higher in dhAT-MSCs) (p < 0.0001). Related to these results, IL-10 may induce TGF-β/SMAD and Canonical Wnt/β-catenin signaling pathways in hAT-MSC exosomes obtained after chondrogenic differentiation. Therefore, using these exosomes for cartilage regeneration can lead to the development of treatment methods.

Perioperative platform for muscle-invasive bladder cancer trials: designs and endpoints.

This review explores the design and endpoints of perioperative platforms in clinical trials for muscle-invasive bladder cancer (MIBC). The choice of clinical trial design in perioperative platforms for MIBC must align with specific research objectives to ensure robust and meaningful outcomes. Novel designs in perioperative platforms for MIBC integrate bladder-sparing approaches. Primary endpoints such as pathological complete response and disease-free survival are highlighted for their role in expediting trial results in perioperative setting. Incorporating patient-reported outcomes is important to inform healthcare decision makers about the outcomes most meaningful to patients. Given the growing body of evidence, potential biomarkers, predictive and prognostic tools should be considered and implemented when designing trials in perioperative platforms for MIBC. Effective perioperative platforms for MIBC trials are critical in enhancing patient outcomes. The careful selection and standardization of study designs and endpoints in the perioperative platform are essential for the successful implementation of new therapies and the advancement of personalized treatment approaches in MIBC.

Less Might Not Be More, but May Be Enough for Some.

Mental health concerns among young adult populations have increased in recent years, with standard treatment approaches presenting many undue barriers (e.g., time and cost constraints and limited availability of therapists). Single-session interventions (SSIs) have been explored as an alternative, scalable intervention to address these barriers to care. We evaluated the acceptability and feasibility of a SSI in a real-world setting and found promising effects of the SSI on symptoms of depression in a young adult population. Given these findings, we offer support for the SSI as an accessible treatment alternative to perhaps be integrated into tiered care treatment models or settings with limited access to care.

The Protective Effect of Adipose Derived Stromal Vascular Fraction on Ovarian Function in Rats with Cyclophosphamide-Induced Ovarian Damage.

To investigate if adipose derived stromal vascular fraction (SVF) treatment has any protective effect on ovarian function in rats with cyclophosphamide (CP) induced ovarian damage. Experimental animal study. Participants/ Materials, Setting, Methods: 25 mature cycling Wistar-Albino rats were randomized into four groups (n=5 per group). Rats in Group 1 and 2 received single dose of intraperitoneal (i.p.) 1 mL/kg sodium chloride 0.9% (NaCl). Group 3 and 4 received single dose of 75 mg/kg i.p. CP. On seventh day, SVF was prepared from adipose tissues of 5 additional rats and Group 1 and 3 received 0.9% NaCl i.p. injections while Group 2 and 4 received 0.2 mL i.p. injections of SVF. On day 21 all rats were euthanized, and serum anti-mullerian hormone (AMH) levels, primordial, primary, secondary, antral, and atretic follicle counts, AMH positive staining follicle counts along with AMH staining intensity of the follicles were evaluated. Among two CP induced ovarian damaged groups, SVF treated group showed significantly higher secondary and antral follicle and lower atretic follicle counts, significantly higher mean serum AMH levels, AMH positive antral follicle count and higher intensity of AMH positive follicle scores for primary, secondary and antral follicles when compared to untreated group. Moreover, Group 1 showed no significant difference for all parameters except antral follicle count and AMH positive staining intensity scores for antral follicles when compared to Group 4. This study was conducted on experimental rat model. Our study demonstrated a significant protective effect of SVF against Cp-induced ovarian damage which reveals the apparent need for further investigation of its precise mechanisms of action as it may provide a new treatment approach for women with premature ovarian failure.

Practice variation in the management of pediatric intussusception: a narrative review.

This review has identified practice variations in several key areas of ileocolic intussusception management. The findings underscore the need for further research in these areas and the establishment of uniform standards aimed at improving the care of children with ileocolic intussusception. • Ileocolic intussusception necessitates rapid diagnosis and a collaborative treatment approach involving emergency medicine, radiology, surgery, and often anesthesia. • A previous study reported variations in the practice of pain management and sedation among these patients. • This narrative review identified practice variations in several key areas within the diagnostic and treatment pathways of ileocolic intussusception.

Managing malignant sublingual gland tumors: a single institution experience with 23 patients

BackgroundDue to the relative rarity of malignant sublingual gland tumors, diagnosing and treating them clinically pose challenges. Hence, there’s a need to explore the pathological types, characteristics, treatment methods, and prognosis of primary malignant tumors of the sublingual gland to improve our understanding and management of these rare yet highly malignant conditions.MethodsThis study reviewed cases of primary malignant sublingual gland tumors, analyzing their characteristics. The treatment methods included surgical excision, with additional radiotherapy, or brachytherapy for advanced stages or positive surgical margins. The study also summarized different treatment approaches, including lymph node dissection and soft tissue reconstruction using free flaps such as the anterolateral thigh flap and forearm flap.ResultsWe have gathered 23 cases of sublingual gland malignancies treated at the Department of Oral and Maxillofacial Surgery, School and Hospital of Stomatology, Wuhan University, from January 2013 to May 2024. The most common pathological types were adenoid cystic carcinoma and mucoepidermoid carcinoma, with rare cases of mucosa-associated lymphoid tissue (MALT) lymphoma and nonspecific salivary gland clear cell carcinoma. Early diagnosis and surgical intervention were crucial for a favorable prognosis. Marginal mandibulectomy was necessary for cases involving the mandible. Patients with positive preoperative lymph node detection required cervical lymph node dissection. Extensive tissue defects in the floor of the mouth were effectively reconstructed with free flaps to prevent oral-mandibular fistula.ConclusionSurgical excision remains the preferred treatment for malignant sublingual gland tumors. Early diagnosis and comprehensive surgical management are essential for improving prognosis. The study’s limitations include a small sample size and short follow-up duration, necessitating further research with larger clinical samples to confirm these findings.

Urinary chloride excretion in critical illness and acute kidney injury: a paediatric hypothesis-generating cohort study post cardiopulmonary bypass surgery.

Renal chloride metabolism is currently poorly understood but may serve as both a diagnostic and a treatment approach for acute kidney injury. We investigated whether plasma chloride, ammonia and glutamine as well as urinary chloride, ammonium and glutamine concentrations may serve as markers for acute kidney injury in paediatric patients. We conducted a prospective observational trial in a tertiary care paediatric intensive care unit. Ninety-one patients after cardiopulmonary bypass surgery were enrolled. Plasma glutamine, creatinine, (serum) albumin, urinary electrolytes and glutamine were collected pre-cardiopulmonary bypass surgery, at paediatric intensive care unit admission, and at 6, 12, 24, 48 and 72 h after paediatric intensive care unit admission. The urinary strong ion difference was calculated. The median urinary chloride excretion decreased from 51 mmol/L pre-cardiopulmonary bypass to 25 mmol/L at paediatric intensive care unit admission, and increased from 24 h onwards. Patients with acute kidney injury had lower urinary chloride excretion than those without. The median urinary strong ion difference was 59 mmol/L pre-cardiopulmonary bypass, rose to 131 mmol/L at 24 h and fell to 20 mmol/L at 72 h. The plasma chloride rose from 105 mmol/L pre-cardiopulmonary bypass to a maximum of 109 mmol/L at 24 h. At 24 h the plasma chloride concentration was associated with the presence of acute kidney injury. There was no association between plasma or urinary amino acids and chloride excretion or kidney injury. In conclusion, renal chloride excretion decreased in all patients, although this decrease was more pronounced in patients with acute kidney injury. Our findings may reflect a response of the kidneys to critical illness, and acute kidney injury may make these changes more pronounced. Targeting chloride metabolism may offer treatment approaches to acute kidney injury.

Secretory Carcinoma of the Breast: Radiologic-Pathologic Correlation.

Secretory carcinoma is a rare, low-grade, special histological type of invasive breast carcinoma. Although it is the most common primary breast cancer in the pediatric population, most cases are diagnosed in adults, with a median age of 48 years (range 3 to 91 years). It most often presents as a painless and slowly growing palpable lump. Imaging findings are nonspecific. Secretory carcinomas have abundant periodic acid-Schiff positive intracytoplasmic and extracellular secretions on histopathology. Nearly all secretory carcinomas have mild to moderate nuclear pleomorphism with low mitotic activity. Over 80% (86/102) of secretory carcinomas display the translocation of t(12;15)(p13;q25), resulting in ETV6::NTRK3 gene fusion. Secretory carcinoma generally has an indolent course and has a better prognosis and overall survival than invasive breast carcinoma of no special type. A good prognosis is associated with age <20 years, tumor size <2 cm, and ≤3 axillary lymph node metastases. Metastases beyond the ipsilateral axillary lymph nodes are rare, with the most common sites involving the lung and liver. Except for the potential addition of targeted drug therapy for NTRK fusion-positive tumors, the treatment approach is otherwise similar to invasive breast carcinomas of similar receptor status.

Impact of sex, serostatus, and smoking on risk for rheumatoid arthritis-associated interstitial lung disease subtypes.

RA-associated interstitial lung disease (RA-ILD) includes multiple subtypes with varying histopathology, prognosis, and potential treatments. Limited research has investigated risk factors for different RA-ILD subtypes. Therefore, we examined demographic, serologic, and lifestyle associations with RA-ILD subtypes. We systematically identified RA-ILD cases and RA-noILD controls in the Brigham RA Sequential Study and Mass General Brigham Biobank RA cohort. We determined RA-ILD subtype (usual interstitial pneumonia [UIP], nonspecific interstitial pneumonia [NSIP], and other/indeterminate) through chest high-resolution computed tomography imaging pattern. We investigated associations between demographic, lifestyle, and serologic factors and major RA-ILD subtypes using multivariable logistic regression. Among 3328 RA patients, we identified 208 RA-ILD cases and 547 RA-noILD controls. RA-UIP was associated with older age (OR 1.03 per year, 95%CI 1.01 to 1.05), male sex (OR 2.15, 95%CI 1.33 to 3.48), and seropositivity (OR 2.08 95%CI 1.24 to 3.48) while RA-NSIP was significantly associated only with seropositive status (OR 3.21, 95%CI 1.36 to 7.56). Non-fibrotic ILDs were significantly associated with smoking (OR 2.81, 95%CI 1.52 to 5.21). Having three RA-ILD risk factors (male, seropositive, smoking) had an OR of 6.89 (96%CI 2.41 to 19.7) for RA-UIP compared to having no RA-ILD risk factors. Older age, seropositivity, and male sex were strongly associated with RA-UIP while RA-related autoantibodies were associated with RA-NSIP. These findings suggest RA-ILD sex differences may be driven by RA-UIP and emphasizes the importance of further studies to clarify RA-ILD heterogeneity and optimize screening and treatment approaches.
