This study sought to examine the relationship between Toxoplasma gondii seropositivity and cognitive function in older adults.
An observational cross-sectional study.
The National Health and Nutrition Examination Survey (NHANES) study took place at participants’ homes and mobile examination centres.
A total of 2956 older adults aged 60 and above from the NHANES from 2011 to 2014 were included in the study. Exposure of interest: participants had serum Toxoplasma gondii antibody analysed in the laboratory. A value>33 IU/mL was categorised as seropositive for Toxoplasma gondii infection; Toxoplasma gondii infection.
Cognitive tests included the Consortium to Establish a Registry for Alzheimer’s Disease Word Learning subtest (CERAD-WL) for immediate and delayed memory, the Animal Fluency Test (AFT), and the Digit Symbol Substitution Test (DSST).
About half of the 2956 participants (mean age 70.0) were female (51.0%), non-Hispanic White (48.3%), and completed some college or above (48.3%). A total of 703 participants were positive for Toxoplasma gondii infection (23.8%). Adjusted linear regression showed that compared with participants with negative Toxoplasma gondii infection, those with positive Toxoplasma gondii infection had lower CERAD-WL immediate memory (beta (β) –0.16, 95% CI –0.25 to –0.07), CERAD-WL delayed memory (β –0.15, 95% CI –0.24 to –0.06), AFT (β –0.15, 95% CI –0.24 to –0.06), DSST (β –0.34, 95% CI –0.43 to –0.26), and global cognition (β –0.24, 95% CI –0.32 to –0.16) z-scores after controlling for the covariates.
Toxoplasma gondii seropositivity is associated with worse immediate and delayed verbal learning, language proficiency, executive functioning, processing speed, sustained attention, working memory, as well as global cognition in older adults. Public health measures aiming at preventing Toxoplasma gondii infection may help preserve cognitive functioning in older adults.

BackgroundPancreatic ductal adenocarcinomas (PDAC) have heterogeneous tumor microenvironments relatively devoid of infiltrating immune cells. We aimed to quantitatively assess infiltrating CD3+ and CD8+ lymphocytes in a treatment-naïve patient cohort and assess associations with overall survival and microenvironment inflammatory proteins.
MethodsTissue microarrays were immunohistochemically stained for CD3+ and CD8+ lymphocytes and quantitatively assessed using QuPath. Levels of inflammation-associated proteins were quantified by multiplexed, enzyme-linked immunosorbent assay panels on matching tumor and tissue samples.
ResultsOur findings revealed a significant increase in both CD3+ and CD8+ lymphocytes populations in PDAC compared with non-PDAC tissue, except when comparing CD8+ percentages in PDAC versus intraductal papillary mucinous neoplasms (IPMN) (p = 0.5012). Patients with quantitatively assessed CD3+ low tumors (lower 50%) had shorter survival (median 273 days) compared to CD3+ high tumors (upper 50%) with a median overall survival of 642.5 days (p = 0.2184). Patients with quantitatively assessed CD8+ low tumors had significantly shorter survival (median 240 days) compared to CD8+ high tumors with a median overall survival of 1059 days (p = 0.0003). Of 41 proteins assessed in the inflammation assay, higher levels of IL-1B and IL-2 were significantly associated with decreased CD3+ infiltration (r = -0.3704, p = 0.0187, and r = -0.4275, p = 0.0074, respectively). Higher levels of IL-1B were also significantly associated with decreased CD8+ infiltration (r = -0.4299, p = 0.0045), but not IL-2 (r = -0.0078, p = 0.9616). Principal component analysis of the inflammatory analytes showed diverse inflammatory responses in PDAC.
ConclusionIn this work, we found a marked heterogeneity in infiltrating CD3+ and CD8+ lymphocytes and individual inflammatory responses in PDAC. Future mechanistic studies should explore personalized therapeutic strategies to target the immune and inflammatory components of the tumor microenvironment.
To explore the knowledge, attitudes and practice (KAP) status of preventing pressure injury among clinical nurses working in paediatric ICU, and to examine factors affecting nurses' KAP. A questionnaire survey was conducted among 1906 paediatric ICU nurses in 18 children's hospitals by convenience sampling method. The survey tools were self-designed general data questionnaire, KAP questionnaire for the prevention of pressure injury and the influencing factors were analysed. A total of 1906 valid questionnaires were collected. The scores of overall KPA, knowledge, attitudes, and practice were 101.24 ± 17.22, 20.62 ± 9.63, 54.93 ± 5.81and 25.67 ± 6.76, respectively. The results of multiple linear regression analysis showed that education background, professional title, age and specialist nurse were the main influencing factor of nurses' knowledge of preventing PI; education background and specialist nurse were the main influencing factors of nurses' attitudes of preventing PI; knowledge, attitudes and education background were the main influencing factors of nurses' practice of preventing PI. Paediatric ICU nurses have a positive attitude towards the prevention of PI, but their knowledge and practice need to be improved. According to different characteristics of nurses, nursing managers should carry out training on the knowledge of prevention of PI to establish a positive attitude, so as to drive the change of nursing practice and improve the nursing practice level of ICU nurses to prevent of PI.
To explore the meaning of healthcare self-management support for post-discharged stroke patients.
Rodgers' evolutionary approach was used to identify antecedents, attributes, related terms, surrogate terms and consequences.
Literature from 2012 to 2022 was searched from MEDLINE, CINAHL, PsycINFO and Google Scholar.
Three antecedents preceded healthcare self-management support for post-discharged stroke patients: loss of inpatient support, preparedness for self-management and presence of self-management support. Healthcare self-management support for post-discharged stroke patients was defined by eight attributes: pre-discharge assessment and planning; provision of continuous education and training; collaborative goal-setting; reinforcement and documentation of vital information; coordination of post-discharge care; provision of rehabilitation support and promoting community reintegration; provision of counselling support; and using clear communication, patient empowerment and promoting self-efficacy. The identified consequences of the concept were as follows: improved patient outcomes; improved life quality; decreased healthcare cost; decreased re-admission rate and inpatient care burden; and decreased complication rate.
Healthcare self-management support for post-discharged stroke patients is an emerging concept that can help to significantly improve stroke patients' health outcomes and life quality. However, its applicability is uncertain considering the workload, time and resources available to healthcare professionals. There is a need for future studies to focus on the feasibility and applicability of this concept in clinical practice and to identify any challenges healthcare providers may have in supporting stroke patients after discharge.
This concept analysis brings clarity to the concept of healthcare self-management support of post-discharged stroke patients and distinguishes it from other self-management supports. It provides an opportunity for further studies and a pathway for generalized healthcare self-management support for stroke patients after discharge to improve health outcomes and quality of life.
No patients, service users, caregivers or members of the public were involved in conducting this concept analysis.
There has been controversy over the use of neoadjuvant chemotherapy or surgery in the treatment of ovarian cancer. The purpose of this meta-analysis is to assess the hazard evaluation of the effect of adjuvant chemotherapy over primary debulking surgery (PDS) on the incidence of wound infection in women with ovarian carcinoma. In this research, we looked at PubMed, Embase and Cochrane Library to evaluate the impact of PDS and chemotherapy on the incidence of wound infections in women with ovarian cancer. Based on the keywords of ‘Ovary Cancer’, ‘Surgical’ and ‘Chemotherapy’, we looked up the data in the digital database, and at last, we selected six of them from 1453 studies. There was no time limitation in the studies. The meta-analyses included studies that described the risk factors of wound infection in ovarian carcinoma patients, particularly those who reported OR value. The Chi-square method was employed to perform statistical analysis of the inter-study heterogeneity, with additional analyses dependent on I 2. A sensitivity analysis was conducted, and a possible publication bias was evaluated. The findings suggest that there is a significant reduction in the rate of wound infections among patients with ovarian cancer treated with primary chemotherapy than with PDS (OR, 2.80; 95% CI, 1.79, 4.39, p < 0.0001). There was a significant reduction in the incidence of thrombus in patients with ovarian cancer who were treated with primary chemotherapy than in those who did have prior surgical intervention (OR, 2.77; 95% CI, 1.34, 5.74, p = 0.006). Our findings indicate that early chemotherapy in ovarian cancer patients may lower their chances of developing wound infection.
Rhinoplasty is a frequently performed aesthetic surgery with a high procedural volume. Despite the operational ease and safety profile of biocompatible materials such as silicone and inflatable prosthetics, postoperative complications like surgical site infections can lead to significant clinical challenges. These complications necessitate effective therapeutic and reconstructive interventions. This study aims to evaluate the efficacy of different flap transplantation techniques for early treatment of post-rhinoplasty nasal tissue deficiencies. A retrospective study was conducted from May 2018 to May 2023, involving 38 patients divided into a control group receiving standard anti-infective treatment and an observation group undergoing early flap grafting procedures. Efficacy was evaluated using objective metrics—namely, nasal appearance, function and flap condition—each assessed through a 10-point scoring system, and subjective metrics such as patient satisfaction gauged through self-administered questionnaires. Statistical analyses were performed using SPSS version 27.0. Both groups were statistically comparable in terms of demographics such as age, marital status and educational background. The observation group displayed significantly improved outcomes in terms of nasal aesthetics (mean score 7.92 ± 1.00), nasal function (mean score 8.47 ± 0.51) and flap condition (mean score 7.89 ± 1.12) compared to the control group. Flap transplantation techniques demonstrated superior therapeutic and reconstructive efficacy in the management of nasal tissue deficiencies arising from post-rhinoplasty surgical infections. These findings contribute to evidence-based recommendations for optimal clinical practice.

Staphylococcus aureus is the main culprit, causing a variety of severe clinical infections. At the same time, clinics are also facing the severe situation of antibiotic resistance. Therefore, effective strategies to address this problem may include expanding the antimicrobial spectrum by exploring alternative sources of drugs or delaying the development of antibiotic resistance through combination therapy so that existing antibiotics can continue to be used. Plumbagin (PLU) is a phytochemical that exhibits antibacterial activity. In the present study, we investigated the in vitro antibacterial activity of PLU. We selected five antibiotics with different mechanisms and inhibitory activities against S. aureus to explore their interaction with the combination of PLU. The interaction of combinations was evaluated by the Bliss independent model and visualized through response surface analysis. PLU exhibited potent antibacterial activity, with half maximal inhibitory concentration (IC50) and minimum inhibitory concentration (MIC) values against S. aureus of 1.73 μg/mL and 4 μg/mL, respectively. Synergism was observed when PLU was combined with nitrofurantoin (NIT), ciprofloxacin (CPR), mecillinam (MEC), and chloramphenicol (CHL). The indifference of the trimethoprim (TMP)-PLU pairing was demonstrated across the entire dose-response matrix, but significant synergy was observed within a specific dose region. In addition, no antagonistic interactions were indicated. Overall, PLU is not only a promising antimicrobial agent but also has the potential to enhance the growth-inhibitory activity of some antibiotics against S. aureus, and the use of the interaction landscape, along with the dose-response matrix, for analyzing and quantifying combination results represents an improved approach to comprehending antibacterial combinations.Postoperative wound infections (PWIs), a subtype of surgical site infections, are a significant concern for patients undergoing caesarean sections (C-sections). Understanding risk factors and pathogen profiles can greatly assist in early diagnosis and effective treatment. This study aimed to identify risk factors and analyse the pathogenic landscape contributing to PWIs in C-sections. A nested case-control study was carried out, utilising stringent criteria for case selection and control matching. Diagnostic criteria for surgical site infections included both clinical and microbiological parameters. Risk variables examined included patient age, Body Mass Index, duration of surgery and several other clinical indicators. Microbiological analysis was performed using the BD Phoenix-100 Automated Bacterial Identification System. Statistical analyses were conducted using SPSS version 26.0, and risk factors were evaluated through both univariate and multivariate analyses. A total of 50 patients, aged between 20 and 45 years (mean age 26.3 ± 5.6), developed PWIs following C-sections. The study revealed a temporal distribution and various clinical indicators of PWIs, including elevated white blood cell count and C-reactive protein levels. Gram-negative bacteria were found to be more prevalent at 57.4%. Notable pathogens included Pseudomonas aeruginosa and Acinetobacter baumannii. Antimicrobial resistance patterns were also identified, highlighting the need for a targeted antibiotic approach. Increased infection risks were linked to lack of prophylactic antibiotics, absence of preoperative povidone-iodine antisepsis, operations over an hour, anaemia, amniotic fluid contamination, diabetes, GTI, premature rupture of membranes and white blood cells counts above 10 × 109/L. The study provides critical insights into the risk factors and microbial agents contributing to PWIs following C-sections. Our findings emphasise the importance of early diagnosis through clinical and laboratory parameters, as well as the need for constant surveillance and reassessment of antibiotic stewardship programs.

BackgroundSepsis, described as an inflammatory reaction to an infection, is a very social health problem with high mortality. This study aims to explore the new mechanism in the progression of sepsis.
MethodsWe downloaded the GSE69528 dataset to screen differentially expressed genes (DEGs) for WGCNA, in which the key module was identified and analyzed by DMNC algorithm, expression verification and ROC curve analysis to identify the hub gene. Furthermore, the hub gene was analyzed by immunoassay, and the potential mechanism of hub gene in neutrophils was investigated by in vitro experiments.
ResultsThe turquoise module was the key module for sepsis in WGCNA on 94 DEGs. The top 20 genes of DMNC network were verified in GSE69528 and GSE9960, and 10 significant genes were obtained for ROC analysis. Based on the ROC curves, HP was considered the hub gene in sepsis, and its expression difference in sepsis and control groups was substantially significant. Further, it was demonstrated the knockdown of HP and PFKFB3 could suppress glycolysis and inflammatory cytokine levels in dHL-60 cell treated with LPS.
ConclusionIn conclusion, HP is identified as a potential diagnostic indicator for sepsis patients, and HP promotes neutrophil inflammatory activation by regulating PFKFB2 in the glycolytic metabolism of sepsis confirmed by in vitro experiments. These will help us deepen the molecular mechanism of sepsis.
More and more meta-analyses have been conducted to compare the effects of intramedullary fixation (IF) and plate fixation (PF) on the outcome of midshaft clavicle fractures. It can affect the doctors' treatment decisions. A number of studies have been conducted in order to assist surgeons in selecting optimal operative procedures and to recommend operative treatment of clavicle fractures in accordance with the best available research. Our analysis of the IF and PF of clavicle fractures was done through a search for PubMed, Emabase, Web of Science, and Cochrane Library. Two different researchers analysed the research literature for quality of analysis and data extraction. The analysis of the data was done with RevMan 5.3. The 95% CI and OR models have been computed by means of either fixed-dose or randomize. In addition, RCT in 114 references have been reviewed and added for further analysis. It is concluded that the application of plate and intramedullary fixation in the middle clavicle operation has remarkable influence on the outcome of post-operation. There was a lower risk of postoperative wound infection in IF (OR, 5.92; 95% CI, 2.46, 14.27 p < 0.0001), smaller surgical incisions (MD, 6.57; 95% CI, 4.90, 8.25 p < 0.0001), and shorter operative time (MD, 17.09; 95% CI 10.42, 23.77 p < 0.0001), less blood loss (MD, 63.62; 95% CI, 55.84, 71.39 p < 0.0001) and shorter hospital stay (MD, 1.05; 95% CI, 0.84, 1.25 p < 0.0001). However, there is no statistical significance in the incidence of wound dehiscence. Thus, the effect of IF on the incidence of injury is better than that of the inner plate in the middle of the clavicle.
This study aimed to analyse the effects of servant leadership on nurses' emotional failure and compliance with standard precautions and to explore the moderating effect of individual resilience.
A cross-sectional survey.
This descriptive cross-sectional study was conducted from October 9 to November 1, 2022. The convenience sampling method was used to collect questionnaire data from 924 clinical nurses in a third-class general hospital in Chongqing, China.
The emotional exhaustion and compliance with standard precautions were at the general level. Servant leadership mediated by emotional exhaustion had a significant positive predictive effect on compliance with standard precautions. Personal resilience played a negative moderating role in the relationship between servant leadership and emotional exhaustion. For nurses with low resilience, servant leadership had a greater impact on emotional exhaustion.
The current compliance with standard precautions for clinical nurses is not high due to emotional exhaustion. The level of servant leadership can alleviate nurses' emotional exhaustion and improve compliance with standard precautions. Especially for nurses with low personal resilience, the care and support of department leaders are needed.
We found that the compliance with standard precautions is not high, and the link between emotional exhaustion, servant leadership and compliance with standard precautions provides a basis for further patient care.
There was no patient or public involvement.
Nurses are the key population for hospital infection prevention and control, and their level of compliance with standard precautions is of great significance for hospital infection prevention and control. However, in practice, nurses' compliance with standard precautions is generally low. Most of the previous studies on nurses' compliance with standard precautions were conducted from the perspective of individual nurses, based on the staff's ‘knowledge, belief, and action’ to study the current status of compliance with standard precautions and the factors affecting adherence, with less attention paid to the influence of psychological, environmental, and organizational factors. Therefore, the study focuses on the impact of servant leadership and emotional exhaustion on standard precautionary adherence, which is of great significance for good care management at the organizational level. It also explored how the impact of servant leadership on emotional exhaustion varies across levels of resilience, which is important for accurately identifying different types of nursing staff and targeting assistance.
The prevalence of dry eye disease (DED) has been consistently increasing yearly. However, the radical therapy has not yet been established. This study is to confirm the superiority of acupuncture over artificial tear drops (ATDs) in patients with DED.
This study is a single-centre, investigator-initiated, assessor-blinded, parallel randomised controlled trial. 30 participants will be enrolled. Over a period of 4 weeks, the experimental group would receive two kinds of acupuncture three times a week. First, body acupuncture would be performed on bilateral BL2, GB14, TE23, EX-HN5 and ST1 for 15 min. Thereafter, intradermal acupuncture would be performed on the same acupoints for 4 hours. On the other hand, the control group would apply the provided ATD at least four times a day. As a rescue medication for severe DED symptoms, both groups can additionally apply ATD. The frequency of ATD use would be recorded during the trial. The primary outcomes are the Ocular Surface Disease Index and tear film break-up time. The secondary outcomes are subjective symptom Visual Analogue Scale, quality of life, Schirmer I test, tear lactoferrin level, treatment satisfaction and safety. The outcomes would be mostly assessed at visits 1, 13 and 14.
This study was approved by the institutional review board of Naju Dongshin University Korean Medicine Hospital (Approval No. NJ-IRB-23-5). The obtained results will be disseminated through publication in a peer-reviewed journal.

Central retinal artery occlusion (CRAO; retinal stroke or eye stroke) is an under-recognized, disabling form of acute ischemic stroke which causes severe visual loss in one eye. The classical risk factor for CRAO is ipsilateral carotid stenosis; however, nearly half of patients with CRAO do not have high-grade carotid stenosis, suggesting that other cardiovascular risk factors may exist for CRAO. Specifically, prior studies have suggested that cardioembolism, driven by underlying atrial fibrillation, may predispose patients to CRAO. We describe the design of an observational, population-based study in this protocol. We evaluate two specific objectives: 1) To determine if atrial fibrillation is an independent risk factor for CRAO after adjusting for medical and cardiovascular risk; 2) To determine if use of oral anticoagulation can modify the risk of CRAO for patients with atrial fibrillation. This protocol lays out our strategy for cohort definition, case and control definition, comorbidity ascertainment, and statistical methods.To investigate the association of hypertension with depressive and anxiety disorders in middle-aged and older Chinese women, and to further assess whether the association was influenced by socioeconomic status (SES).
Nationwide cross-sectional study.
Six provinces of the eastern, central and western regions of China.
Women aged 40–70 years were included by a multistage stratified random cluster sampling in 2018 (N=9900).
Depressive and anxiety disorders were measured by the Patient Health Questionnaire-9 and the Generalized Anxiety Disorder-7, respectively. Logistic regression models were used to evaluate the OR and 95% CI for hypertension and the odds of depressive and anxiety disorders.
18.5% of participants reported having hypertension; 20.9% and 15.3% of women experienced depressive and anxiety disorders, respectively. After adjusting for potential confounders, women diagnosed with hypertension were more likely to have depressive (OR=1.27, 95% CI 1.11 to 1.45) and anxiety disorders (OR=1.48, 95% CI 1.28 to 1.71) than those without hypertension. Stratified analyses demonstrated that hypertension was significantly associated with higher odds of depressive disorders in women living in rural areas (OR=1.34, 95% CI 1.13 to 1.59), with lower levels of education (OR=1.28, 95% CI 1.12 to 1.46) and with average monthly household income
Hypertension was associated with increased odds of depressive and anxiety disorders among middle-aged and older women, especially in those with low SES. Effective strategies and actions for identification and management of hypertension and depressive and anxiety disorders are needed.

Previous studies showed that physical activity (PA) is concerned with hypertension (HTN). However, the mediation and interaction role of the obesity index: body mass index (BMI), waist-hip ratio (WHR), body fat rate (BFR) and visceral fat index (VFI) between PA and HTN has never been studied. Therefore, the purpose of this study was to assess the mediation and interaction of the obesity index between moderate-vigorous recreational physical activity (MVRPA) and HTN. We conducted a cross-sectional study of 4710 individuals aged 41 or older in Torch Development Zone, Zhongshan City. The mediation and interaction of the obesity index were evaluated by a four-way decomposition. 48.07% of participants had HTN among these groups. In the adjusted linear regression model, MVRPA was significantly correlated with WHR (β±SE = -0.005±0.002; POR) = 1.35), 95% (confidence interval (CI) = 1.17–1.56), insufficient MVRPA increased the risk of developing HTN. Furthermore, there were associations between BMI, WHR, BFR, VFI and HTN where the adjusted ORs and 95% CIs were 1.11 (1.09–1.13), 6.23 (2.61–14.90), 1.04 (1.03–1.06), 1.07 (1.06–1.09), respectively. The mediation analyses suggested that the impact of MVRPA on HTN risk may partly be explained by changes in obesity index, with a pure indirect mediation of WHR between MVRPA and HTN (Pby Haoyu Liu, Xiaojin Song, Lu Xiong, Liyun Zhang, Bingquan Luo, Siling Liu
BackgroundAnxiety is a common preoperative symptom in children with simple congenital heart disease (SCHD). Music therapy shows potential as a non-drug intervention. However, it is unclear how it impacts the level of cooperation during the induction of anesthesia and preoperative anxiety, as well as the factors that influence its effectiveness. Therefore, we will conduct a comprehensive review and meta-analysis to assess the impact of music therapy on the level of cooperation during anesthesia induction and preoperative anxiety in children with SCHD.
MethodsElectronic searches will be conducted through various databases including PubMed, Embase, Web of Science, Medline, and CNKI to gather randomized controlled trials (RCTs) examining the impact of music therapy on the level of cooperation during anesthesia induction and preoperative anxiety among children with SCHD. Two evaluators will independently review the literature, extract information, and assess the risk of bias in the included studies. Afterwards, data analysis will be conducted using Stata 14.0 software and Revman 5.4 software. The results will be based on random-effects models. The reliability and quality of evidence will be evaluated by using the Grading of Recommendations, Development, and Evaluation (GRADE) system. Heterogeneity will be examined by subgroup analysis stratified by age, gender ratio, type of surgery, drop-out rate, measurement tools, and country of origin. We will assess potential publication bias using funnel plot symmetrical and Begg’s ang Egger’s regression tests.
DiscussionGiven the multiple advantages that may be associated with music therapy, this therapy may be a desirable alternative to existing therapies for preoperative cooperation and anxiety issues in children with SCHD. We hope that this systematic review will guide clinical decision-making for future efforts related to coping with preoperative fit and anxiety in children with SCHD.

High myopia is a pressing public health concern due to its increasing prevalence, younger trend and the high risk of blindness, particularly in East Asian countries, including China. The China Alliance of Research in High Myopia (CHARM) is a newly established consortium that includes more than 100 hospitals and institutions participating across the nation, aiming to promote collaboration and data sharing in the field of high myopia screening, classification, diagnosis and therapeutic development.
The CHARM project is an ongoing study, and its initiation is distinguished by its unprecedented scale, encompassing plans to involve over 100 000 Chinese patients. This initiative stands out not only for its extensive scope but also for its innovative application of artificial intelligence (AI) to assist in diagnosis and treatment decisions. The CHARM project has been carried out using a ‘three-step’ strategy. The first step involves the collection of basic information, refraction, axial length and fundus photographs from participants with high myopia. In the second step, we will collect multimodal imaging data to expand the scope of clinical information, for example, optical coherence tomography and ultra-widefield fundus images. In the final step, genetic testing will be conducted by incorporating patient family histories and blood samples. The majority of data collected by CHARM is in the form of images that will be used to detect and predict the progression of high myopia through the identification and quantification of biomarkers such as fundus tessellation, optic nerve head and vascular parameters.
The study has received approval from the Ethics Committee of Beijing Tongren Hospital (TREC2022-KY045). The establishment of CHARM represents an opportunity to create a collaborative platform for myopia experts and facilitate the dissemination of research findings to the global community through peer-reviewed publications and conference presentations. These insights can inform clinical decision-making and contribute to the development of new treatment modalities that may benefit patients worldwide.
