ABSTRACT

BACKGROUND: The most common deformity of the ear or earlobe appearing after a facelift is the pixie ear deformity.

OBJECTIVES: The purpose of this study was to devise and exercise a method to prevent ear deformity, including pixie ear, when performing a facelift and to correct it if it has already occurred.

METHODS: Extended deep-plane rhytidectomy was performed between January 2017 and May 2024, and 76 patients who had passed 12 months post-surgery were included in this study. Group 1 consisted of 40 patients, who underwent W-plasty of incision and combined Botulinum neurotoxin type A (BoNTA) injection around the incision site. Group 2 consisted of 36 patients, who underwent rotation of the lower earlobe after W-plasty of incision and combined Botulinum neurotoxin type A (BoNTA) injection around the incision site.

RESULTS: In a postoperative comparison between the two groups, Group 2 demonstrated superior outcomes over Group 1 by 8.4% on the right and 8.9% on the left, which was statistically significant (p=0.007, p=0.006).

CONCLUSIONS: Partial rotation of the earlobe is demonstrated as a practical and effective surgical approach to prevent and correct pixie ear deformity.

ABSTRACT

The gut microbiome has emerged as an important environmental factor in the pathogenesis of autoimmune diseases. Advances in high-throughput sequencing technologies have enabled comprehensive characterization of the gut microbiome, providing detailed insights into its composition and functional potential. These approaches have been widely applied in autoimmune disease research, revealing disease-associated alterations in the gut microbiome of patients with conditions such as rheumatoid arthritis and systemic lupus erythematosus. In addition, microbiome sequencing data can be leveraged to investigate the gut virome, including viruses residing in the intestinal ecosystem. This review summarizes current evidence linking autoimmune diseases and the gut microbiome, with a particular focus on studies employing microbiome sequencing-based analyses.

ABSTRACT

BACKGROUND: The effect of β-blockers on heart failure (HF) with preserved ejection fraction (HFpEF) remains controversial. One proposed reason is the confounding influence of common comorbidities such as atrial fibrillation (AF) and ischemic heart disease (IHD), which may obscure the influence of β-blockers on HFpEF outcomes.

METHODS AND RESULTS: From the PURSUIT-HFpEF registry (UMIN000021831), patients were divided into two groups: AF/IHD (with AF and/or IHD) and non-AF/IHD (without both). Prognosis was compared between β-blocker users and non-users in each group. Inverse probability of treatment weighting (IPTW) was performed as the primary adjustment method. In AF/IHD cohort (n=687; β-blocker 361, non-β-blocker 326), outcomes did not differ for the composite endpoint, all-cause death, or HF rehospitalization. In contrast, in non-AF/IHD patients (n=537; β-blocker 203, non-β-blocker 334), β-blocker use was linked to poorer outcomes. In IPTW-weighted analyses, β-blocker use was not associated with the composite endpoint, all-cause death, or HF rehospitalization in the AF/IHD group. In contrast, among non-AF/IHD patients, β-blocker use was associated with a higher risk of all-cause death (p=0.046, hazard ratio [HR] 1.448, 95% confidence interval [CI] 1.007-2.082) and cardiac death (p=0.001, HR 2.380, 95% CI 1.406-4.027), as well as a higher risk of cardiac composite outcomes (p=0.039, HR 1.441, 95% CI 1.018-2.039). Formal interaction testing between β-blocker use and AF/IHD status was not statistically significant across endpoints.

CONCLUSIONS: In HFpEF patients without AF or IHD, β-blocker use was associated with higher mortality-related risk, indicating that routine β-blocker use in this subgroup should be interpreted with caution.

ABSTRACT

<b>Introduction:</b> Trauma remains the leading cause of death in the pediatric population under 18 years of age. Non-operative management (NOM) has become the standard of care for hemodynamically stable pediatric patients with nonpenetrating abdominal injuries. <br><br><b>Aim:</b> This study evaluates the application of the American Pediatric Surgery Association (APSA) guidelines in a pediatric trauma center in Krakow, Poland, between 2017 and 2024. <br><br><b>Methods:</b> A retrospective analysis was conducted on 295 pediatric patients hospitalized with multi-organ injuries, including the intra-abdominal ones. The data were analyzed with respect to injury severity, hospitalization duration, and outcomes. Statistical methods included Shapiro-Wilk tests, Mann-Whitney U tests, Spearman's rho correlation, and chi-square tests. P-value of less than 0.5 was considered significant. <br><br><b>Results:</b> Conservative treatment was effective in all implemented cases, with no complications or rehospitalizations. Hospitalization duration correlated with age and presence of central nervous system (CNS) or thoracic injuries in multi-organ injuries, but not with sex or radiological American Association for the Surgery of Trauma (AAST) organ injury scales. Within abdominal organs, liver injury had the greatest impact on hospital stay length. Surgical intervention was required only in hemodynamically unstable patients or selected high-grade pancreatic injuries. Conservative management following APSA guidelines proved to be safe and effective, though concurrent injuries often prolonged hospitalization. Hospital stay length appeared to better reflect overall trauma severity than organ-specific injury grading. Imaging included eFAST (Extended Focused Assessment with Sonography in Trauma) and contrast-enhanced computed tomography (CEST); follow-up was typically conducted with standard ultrasound. No long-term complications were reported on. <br><br><b>Conclusions:</b> The application of APSA guidelines in diagnostic and therapeutic management in pediatric patients with blunt abdominal trauma is safe and effective. Nonoperative management remains the gold standard for stable pediatric abdominal trauma patients. <br><br><b>Significance for the field:</b> Conservative treatment of blunt abdominal injuries in children is a safe way of patient management and needs a raised awareness, especially among non-pediatric surgeons.

ABSTRACT

<b>Introduction:</b> Adolescent gynecomastia is a common benign enlargement of male breast tissue that may cause significant psychosocial distress. Persistent cases often necessitate surgical intervention. This study aimed to evaluate clinical features, surgical techniques, outcomes, complications, and patient satisfaction in adolescents undergoing gynecomastia surgery at a single center. <br><br><b>Aim:</b> The present study was undertaken to retrospectively analyze the clinical characteristics, surgical techniques utilized, treatment outcomes, complications, and patient satisfaction following surgical management of gynecomastia in adolescent boys treated at a single surgical center for the macro-region of western Poland between 2000 and 2025. The study also aimed to identify factors associated with treatment results to improve and individualize patient care in this population. <br><br><b>Methods:</b> A retrospective observational study analyzed data from 26 boys aged 10-17 years who underwent surgical treatment for unilateral or bilateral gynecomastia between 2000 and 2025 at the Clinic of Pediatric Surgery, Traumatology, and Urology, Karol Jonscher Clinical Hospital, Poznan University of Medical Sciences. Surgical management primarily involved periareolar excision of glandular tissue, with selective liposuction or skin resection based on severity. Collected data included demographics, gynecomastia laterality, operative times, histopathology, complications, and patient satisfaction (5-point Likert scale). Statistical analyses included descriptive statistics, t-tests, Mann-Whitney U tests, chi-square tests, and Spearman correlation. <br><br><b>Results:</b> Bilateral gynecomastia was predominant (77%), with a median age at surgery of 16 years. Mean operative time was longer for bilateral procedures (58.5 min) than for unilateral ones (38.3 min). Histopathology confirmed benign glandular tissue in most cases. Postoperative complications were rare (11.5% hematomas; one transfusion), and no reoperations were required. Overall satisfaction was high (median 4/5), though older adolescents reported slightly lower satisfaction (Rs = -0.395, p = 0.046). <br><br><b>Conclusions:</b> Surgical management of adolescent gynecomastia is safe, effective, and associated with high patient satisfaction. Bilateral cases require longer operative times, but complication rates remain low. Individualized preoperative planning, including weight optimization and age-appropriate counseling, enhances cosmetic and psychosocial outcomes. These results support timely surgical intervention in adolescents with persistent gynecomastia causing aesthetic or psychological concerns.

ABSTRACT

Anterior cruciate ligament (ACL) rupture in young athletes is a common and devastating injury. The gold standard for treatment in young athlete population remains reconstruction using autografts especially bone-patellar tendon-bone (BTB) graft and hamstring tendons (HT) graft. A systematic review was conducted to compare the rates of overall return to sport (RTS), return to preinjury levels, and re-ruptures between young athletes who have undergone primary ACL reconstruction using a BTB versus HT autograft. 30 studies were included in the final analysis. A total of 5871 patient-athletes who underwent ACL reconstruction were included. Among them, 1684 patients received BTB and 4187 patients received HT. The overall RTS rate was 73.8%. The overall re-rupture rate was 4.2%. Higher rates of RTS and return to preinjury level, as well as a lower re-rupture rate, were observed in the BTB autograft. However, these differences did not reach statistical significance.

ABSTRACT

INTRODUCTION: A high peak knee abduction moment (pKAM) during change-of-direction (COD) movements is considered a risk factor for non-contact injury to the anterior cruciate ligament during multidirectional team sports. COD technique training aimed at avoiding injury-prone movement patterns can lead to reductions in the pKAM but may limit COD performance. In this study we investigated a novel constraints-led training approach based on a 1-on-1 laser tag game, which may optimize COD movement patterns simply through the game’s constraints rather than technique instructions. Specifically, we investigated whether the constraints-led training approach reduces the pKAM but with COD performance maintained or even improved.

METHODS: Twelve highly active individuals (75% female) with experience in COD sports completed an eight-week laser tag training (LASG) intervention while COD biomechanics and performance were obtained from 3D motion capture and full-body musculoskeletal modeling of a maximum-speed 135° COD. Training effects in the LASG group were compared to training effects of traditional COD technique training (CODG) and linear sprint training (CG) obtained from a previous study.

RESULTS: After the training, the LASG showed a statistically significant reduction in the pKAM compared to pre-training (p = 0.038, Cohen’s d = 0.63) with magnitudes comparable to the CODG (p = 0.056, d = 0.58). Further, the LASG showed improvements in COD performance, quantified through statistically significant reductions in COD completion times (p < 0.001, d = 2.47), which was not observed for CODG (p = 0.898, d = 0.04).

DISCUSSION: In conclusion, an eight-week laser tag training intervention can reduce the pKAM and improve performance during a maximum-speed COD and thus may be a useful tool in ACL injury prevention training.

ABSTRACT

BACKGROUND: Assessment of the prognosis, follow-up monitoring, and adjuvant treatment decision-making for patients with stage II and III colorectal cancer (CRC) are controversial, as CRC harbors tremendous heterogeneity. Carcinoembryonic antigen (CEA) is an important tumor marker; however, the use of this marker in the management of CRC has not garnered adequate attention.

AIM: To determine the significance of perioperative CEA levels in prognostic stratification and treatment decision making to provide personalized diagnosis and treatment for patients with stage II and III CRC.

METHODS: Patients in the training and validation cohorts were diagnosed with primary stage II or III CRC. Preoperative CEA (pre-CEA) and postoperative CEA (post-CEA) were collectively defined as perioperative CEA. Kaplan-Meier (K-M) survival analyses were used to describe patient survival. Cox stepwise regression analysis based on Akaike information criterion was used to determine the prognostic value of clinicopathological characteristics. Nomograms were developed to predict the probability of overall survival (OS) and disease-free survival (DFS). Annual hazard curves and pie charts were used to demonstrate the features of recurrence or metastasis. Differences were considered statistically significant at P < 0.05.

RESULTS: A total of 2496 and 1293 patients were included in the training and validation cohorts, respectively. K-M analysis indicated that patients with elevated perioperative CEA had poorer OS and DFS, with post-CEA being an independent prognostic factor for OS and DFS. Nomograms based on factors associated with prognosis were constructed, which showed good predictive ability for 3-, 5-, and 7-year OS and DFS. Patients with elevated perioperative CEA were more likely to have recurrence or metastasis, and the period of the second year after surgery was the peak time of recurrence or metastasis. OS and DFS were significantly worse in patients without adjuvant chemotherapy when they had elevated perioperative CEA. Adjuvant chemotherapy could significantly improve the OS of patients with elevated perioperative CEA. Patients with elevated post-CEA who received XELOX could achieve better OS and DFS.

CONCLUSION: Perioperative CEA demonstrate sufficient sensitivity in the prognosis prediction and follow-up of patients with stage II and III CRC. Furthermore, perioperative CEA, especially post-CEA, show promise in guiding adjuvant chemotherapy, suggesting potential for further study.

ABSTRACT

The brewing process is a crucial step in determining the flavor profile of green tea infusions. However, the flavor differences arising from top-brewing and bottom-brewing methods remain poorly understood, and the underlying mechanisms are largely unexplored. In this study, GC-MS and sensory analysis were employed to investigate the flavor differences in Shucheng Little Cymbidium tea infusions under varying water temperatures and brewing methods. Subsequently, the variations in major polyphenolic compounds were analyzed, and the potential causes of flavor differences were explained from the perspective of the interactions between EGCG and key aroma compounds. Multivariate statistical analysis revealed that compounds such as geraniol, nonanal, and methyl salicylate serve as important markers for discriminating between different brewing conditions. Moreover, EGCG exhibited a significant binding effect with compounds such as geraniol and nonanal, driven by hydrogen bonding and hydrophobic interactions. This binding may regulate the transfer of aroma compounds from tea leaves to the infusion during brewing, thereby shaping distinct sensory characteristics. These findings provide a molecular-level rationale for empirical techniques in traditional tea art. More importantly, it inspires researchers to pay attention to the crucial role of the tea infusion matrix in determining flavor.

ABSTRACT

INTRODUCTION: Globally, trauma patients suffer from high rates of preventable deaths, in part driven by low rates of access to and application of resource-relevant evidence-informed clinical guidance. This mixed-methods study assessed the accessibility (barriers to attempting to use guidance), clarity (ease of comprehension), utility (based on resources and time), and implementation of trauma guidance for Peruvian injury providers.

METHODS: Semistructured qualitative interviews were conducted in Spanish at three hospitals in Lima, Peru. Interviews were analyzed in Dedoose V.9.1.12 using an iteratively developed codebook; quantitative self-administered surveys were then developed and distributed at the Pan American Trauma Society Conference. Surveys were analyzed using descriptive statistics and frequencies.

RESULTS: 38 interviews and 83 surveys were conducted with surgical attendings, emergency physicians, and surgical and emergency residents across all years of training. Access barriers included paywalls, language barriers, low user-friendliness, and technology limits (poor internet, few computers). A mobile app and portable physical guidance are preferred potential solutions. Utility barriers included low equipment maintenance and high patient volumes. Resource-based guidance, conciseness (eg, flowcharts), and standardization are perceived to potentially increase utility. Implementation barriers included limited training time, reliance on more experienced colleagues rather than guidance, low enforcement, and low funding. Potential facilitators are increased administrative support and staff willingness to use guidance improving patient mortality, clinical errors, and length of stay. No barriers to clarity were reported.

CONCLUSION: Barriers to using clinical guidance included low user-friendliness, low local applicability, and an unsupportive culture. Mobile apps, resource stratification, and administrative involvement are priorities to address these needs. Trauma guidance adapted to local realities may reduce preventable deaths in acute care. Further work is needed to identify how to create and distribute updated clinical guidance to better serve trauma providers worldwide.
