Aortoesophageal Fistula: Mending the Lethal Connection-A Systematic Review and Meta-Analysis.

BACKGROUND: Aortoesophageal fistula (AEF) is a rare, life-threatening condition with limited high-quality evidence to guide management. METHODS: We conducted a systematic review and meta-analysis of PubMed and Scopus through December 2025, evaluating survival and complication outcomes according to treatment strategy and morphological severity. Patients were categorized into 5 groups: TEVAR alone, staged TEVAR followed by surgery, primary open or hybrid surgery, TEVAR with esophageal stenting, and supportive/palliative care. Outcomes were pooled as proportions with 95% confidence intervals (CIs). RESULTS: A total of 167 reports representing 528 patients were included. Overall 30-day mortality was 31.2% (95% CI 27.0% to 35.7%) and 1-year mortality 41.2% (95% CI 36.2% to 46.4%). Infection occurred in 32.6%, reintervention in 20.2%, and recurrence in 13.2%. Staged TEVAR followed by surgery showed favorable survival (30-day 12.7%, 1-year 26.1%) but high infection (66.7%) and reintervention (43.2%) rates. TEVAR with esophageal stenting had the lowest early mortality (5.0%) but frequent reintervention (54.5%) and 1-year mortality of 33.3%. TEVAR alone demonstrated the lowest 1-year mortality among definitive strategies (25.5%) but notable recurrence (26.9%). Primary open or hybrid surgery carried higher early and late mortality, while supportive/palliative care had the worst outcomes. Morphological severity correlated strongly with mortality, infection, reintervention, and recurrence, with type IV lesions showing particularly poor prognosis. CONCLUSION: Despite contemporary management, AEF carries high early and late mortality. Definitive strategies, particularly staged TEVAR followed by surgery, offer improved survival but increased complications. Morphology-guided, individualized management is recommended.

Glaucoma filtering surgery combined with phacoemulsification in the era of new aqueous humor filtration devices: A systematic review.

We evaluate the efficacy and safety of filtering glaucoma surgeries combined with phacoemulsification (PCE)-including new aqueous humor drainage devices-compared to standalone procedures. We performed a systematic search up to March 23, 2025, including all comparative studies assessing trabeculectomy (TRAB), non-penetrating deep sclerectomy (NPDS), Xen® Gel Stent (XEN), or Preserflo® MicroShunt (PMS) combined with PCE, versus the same surgery alone. Key exclusion criteria include inadequate follow-up (less than 12-month), absence of a defined success criterion, more than 50% of loss to follow-up at 12-month, and lens extraction performed without PCE. Main outcome was surgical success at ≥ 12 months. Secondary outcomes included intraocular pressure (IOP) reduction, decrease in hypotensive medications, and rates of complications. A total of 27 studies were included for analysis. Among studies comparing TRAB/PCE with standalone TRAB, half reported similar success rates, while others favored standalone TRAB, particularly using strict IOP thresholds. Safety profiles were comparable. For NPDS/PCE, data mostly showed equivalent outcomes versus standalone NPDS, with comparable safety. In studies on XEN/PCE and PMS/PCE, results suggested similar rates of surgical success, efficacy in IOP and medication reduction, and safety compared to their stand-alone procedures. Small differences occasionally favored standalone procedures under stricter success definitions. Current evidence suggests that combined filtering glaucoma surgery provides long-term efficacy and safety comparable to standalone, though some subgroups and outcome thresholds may slightly favor standalone approaches. The limited availability of high-quality prospective trials underscores the need for further large-scale robust studies.

Mitomycin C in the Endoscopic Treatment of Airway Stenosis: A Systematic Review and a Meta-Analysis.

OBJECTIVE: To assess the efficacy of adjuvant MMC in the endoscopic treatment of airway stenoses. DATA SOURCES: PubMed/MEDLINE, Cochrane Library, Scopus, Embase, and Google Scholar databases. REVIEW METHODS: A literature search was conducted following PRISMA guidelines. The PICOS tool was used to determine the eligibility criteria for this study. A single arm meta-analysis was performed for stenosis resolution, the rate of patients requiring multiple endoscopic procedures, and the rate of patients requiring other surgical treatments. RESULTS: A total number of 358 patients (median age: 48.0 years; 95% CI 44.8-50.8) were included. The median follow-up was 25.2 months (n = 244/358; 95% CI 15.4-38.3). Overall, the cumulative stenosis resolution rate was 76.37% (n = 187/254; 95% CI 59.72-89.64), the rate of patients requiring multiple endoscopic procedures was 52.33% (n = 131/260; 95% CI 32.03-72.25), and the rate of patients requiring other surgical treatments was 4.08% (n = 26/310; 95% CI 0.37-11.48). The median intervention-free interval was 366 days (n = 155/358; 95% CI 270-696). CONCLUSIONS: Current evidence does not allow definitive conclusions regarding the efficacy of adjuvant MMC in reducing recurrence or prolonging intervention-free intervals in airway stenosis. Further well-designed prospective studies are needed to clarify the role of MMC and to inform evidence-based guidelines for patient selection and treatment use. LEVEL OF EVIDENCE: NA.

Adjuvant CDK4/6 inhibitors in early-stage breast cancer: Clinical evidence and considerations for risk stratification and treatment selection.

Hormone receptor-positive, human epidermal growth factor receptor 2-negative breast cancer is the most common biologic subtype and carries a persistent risk of recurrence, particularly in patients with high-risk, early-stage disease. Cyclin-dependent kinase 4 and 6 inhibitors, initially established as a standard component of first-line therapy in the metastatic setting based on improvements in progression-free and overall survival, have since been evaluated in the adjuvant setting. While adjuvant palbociclib did not improve invasive disease-free survival, the monarchE and NATALEE trials demonstrated that abemaciclib and ribociclib, respectively, reduce recurrence risk in patients with high-risk, early-stage disease, with emerging overall survival data further supporting their use. However, the absolute magnitude of benefit varies substantially with baseline risk, and treatment-related toxicity and adherence challenges must be considered, as approximately 20% to 25% of patients discontinue therapy before completion. The integration of these agents into clinical practice also intersects with ongoing efforts to deescalate axillary surgery, as treatment eligibility has been largely defined by anatomic staging, particularly nodal status. Available data suggest that the incremental impact of axillary surgery on identifying candidates for cyclin-dependent kinase 4 and 6 inhibition is modest, especially among the favorable-risk populations now eligible for surgical deescalation. As the field evolves, advances in molecular risk stratification, genomic profiling, and dynamic biomarkers are poised to shift treatment selection from anatomic staging toward biologically driven approaches. Multidisciplinary decision-making that integrates tumor biology, anticipated absolute benefit, toxicity, patient preferences, and surgical considerations will be essential to ensure individualized care.

Targeting depression before it starts: An updated systematic review and meta-analysis of preventive interventions in young adults from randomized controlled trials.

INTRODUCTION: Young adulthood is a high-risk period for major depressive disorder (MDD) onset yet is underrepresented in prevention research. This systematic review and meta-analysis examined the effectiveness of psychosocial preventive interventions in adults aged 18-25 years, focusing on symptom reduction, medium- and long-term effects, and MDD onset. METHODS: We conducted a PRISMA-compliant systematic review and meta-analysis (PROSPERO: CRD42024625481) of randomized controlled trials (RCTs) of psychosocial preventive interventions for depression in young adults (18-25) published up to April 15, 2025. Between-group symptom reduction was quantified using Hedges' g and pooled with random-effects models. Outcomes were analyzed at post-intervention, 6-, and 12-month follow-up. Effects on MDD onset were assessed via risk ratio (RR). Risk of bias was assessed with the RoB-2 tool. RESULTS: We included 65 interventions from 58 RCTs (N = 11,333; mean age 20.4; 61.6% female), with 92.8% rated high risk of bias. Interventions at post-test reduced depressive symptoms vs. controls (k = 65; g = -0.52; 95%CI:-0.70;-0.33; p < 0.01), with significant heterogeneity (I2 = 93.0%). Indicated, guided, and face-to-face interventions outperformed universal, selective, self-guided, and online interventions. Effects on symptomatology were highly heterogeneous and non-significant at 6- (k = 8) and 12-month (k = 4) follow-up. Four RCTs were identified evaluating MDD onset risk; pooled effects suggested a reduction in MDD onset (RR = 0.77; 95%CI:0.61;0.97; p < 0.01) though risk of bias was high and samples were highly selective. INTERPRETATION: Psychosocial preventive interventions modestly reduce depressive symptoms at post-test and may lower onset risk in highly selective populations. However, findings remain limited by high risk of bias, scarce data on the long-term sustainability of effects, and unclear mechanisms.

Evidence-based insights into medial pedicle reduction mammaplasty: A systematic review and meta-analysis.

BACKGROUND: Breast reduction relieves the physical and psychosocial burden of macromastia. Medial pedicle reduction mammaplasty may enhance vascular reliability, preserve nipple-areola complex (NAC) sensation, and sustain upper pole fullness, even in large-volume reductions. The purpose of this study was to assess the outcomes of medial pedicle breast reduction. METHODS: A search across ScienceDirect, Cochrane, and PubMed was conducted. Included studies reported on perioperative outcomes and complications of medial pedicle breast reduction. Data on demographics, surgical variables, complications, sensory recovery, volumetric changes, and patient satisfaction were extracted. Proportion meta-analysis was performed, and odds ratios were calculated for comparison with inferior pedicle breast reduction. RESULTS: Twenty-five studies comprising 1033 patients met the inclusion criteria. Mean BMI ranged from 27 to 42 kg/m2, with mean resection weights between 412 and 3828 g. Mean surgical times ranged from 104 to 204 min. Pooled complication rates were low: infection 1%, seroma 1%, hematoma 1%, fat necrosis 2%, NAC necrosis 1%, dehiscence 8%, and reintervention 5%. Odds of complications did not differ significantly from inferior pedicle reductions. NAC sensation typically recovered by 6-12 months, with no long-term deficits. Volumetric analyses demonstrated stable breast shape after the first postoperative year, with superior upper pole tissue maintained. Patient satisfaction ranged 75-100%, with higher ratings for scar appearance and overall aesthetics in medial pedicle reductions. CONCLUSION: Medial pedicle breast reduction is a well-established and reproducible technique, preserving NAC sensation, achieving stable long-term shape, and enhancing upper pole fullness. It offers satisfactory aesthetic outcomes compared to other traditional methods, even in large-volume reductions.

Astigmatic vector outcomes after FS-LASIK versus SMILE for high myopic astigmatism: a single-center retrospective comparative cohort study without cyclotorsion compensation.

PURPOSE: To compare astigmatic correction vector outcomes between femtosecond laser-assisted in situ keratomileusis (FS-LASIK) and small-incision lenticule extraction (SMILE, also termed Keratorefractive Lenticule Extraction, KLEx) without intraoperative cyclotorsion compensation in patients with high myopic astigmatism (- 2.00 to - 3.75 D), and to clarify procedure-specific correction tendencies under this non-standardized alignment protocol. METHODS: This single-center retrospective comparative cohort study enrolled 155 eyes (one eye randomly selected per patient) that underwent FS-LASIK (80 eyes) or SMILE/KLEx (75 eyes) for high myopic astigmatism correction from January 2023 to July 2024 in Beijing Fenglian Jiayue Lige Clinic. Intraoperative cyclotorsion compensation was intentionally disabled to isolate inherent procedural astigmatism correction characteristics. Standardized Alpins vectorial analysis was performed at 3 months and 12 months postoperatively. PRIMARY ENDPOINT: 12-month Alpins correction index (CI). Multivariable propensity score adjustment was applied to mitigate confounding by clinical treatment selection bias. Statistical multiplicity control was implemented for secondary vector and visual outcomes. RESULTS: Baseline demographic, refractive, corneal and ocular biometric parameters were balanced between groups after propensity matching. No statistically significant intergroup differences were detected in uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), residual cylinder, safety index or efficacy index at 3 and 12 months (all P > 0.05). Under the non-cyclotorsion-compensated protocol, significant intergroup differences were identified in the magnitude of surgically induced astigmatism (SIA), correction index (CI), and magnitude error (ME) at both follow-up timepoints (all P < 0.0001). Target induced astigmatism (TIA), difference vector (DV), index of success (IOS), and angle error (AE) magnitudes were comparable between groups (all P > 0.05). The vector mean axis of DV differed significantly between groups at 3 and 12 months (Watson-Williams circular test, all P < 0.0001). No reoperations were documented in clinic medical records for either cohort. No standardized dry eye questionnaires, tear film testing or corneal nerve density metrics were collected to quantify dry eye adverse events; only unstructured clinical notes were reviewed for complication screening. CONCLUSIONS: Under surgical alignment without cyclotorsion compensation, FS-LASIK and SMILE/KLEx both yielded acceptable visual and refractive safety/efficacy for high myopic astigmatism (- 2.00 to - 3.75 D) at 1-year follow-up, but demonstrated divergent astigmatism correction tendencies: FS-LASIK exhibited relative astigmatism overcorrection (vector mean DV: - 0.35 ± 0.43 D × 91°, CI > 1), while SMILE/KLEx showed relative undercorrection (vector mean DV: - 0.21 ± 0.53 D × 12°, CI < 1). These correction biases are specific to the study's manual limbal alignment protocol without cyclotorsion tracking and cannot be generalized to modern optimized surgical platforms equipped with automated cyclotorsion compensation. Residual refractive errors across both groups are likely multifactorial, including differential corneal stromal healing responses, divergent femtosecond/excimer laser tissue modification mechanisms, and uncorrected intraoperative ocular cyclotorsion.

ALID score for treatment-effect heterogeneity of adjunctive low-voltage area ablation in persistent atrial fibrillation: A post hoc analysis of SUPPRESS-AF.

BACKGROUND: In persistent atrial fibrillation (AF), the incremental benefit of adjunctive low-voltage area (LVA) ablation beyond pulmonary vein isolation (PVI) remains inconsistent. OBJECTIVE: To examine whether a simple clinical score characterizes treatment-effect heterogeneity of adjunctive LVA ablation among patients with mapped LVA > 5 cm2 and to perform an exploratory supportive analysis in an independent randomized cohort. METHODS: In this post-hoc analysis of SUPPRESS-AF, which included patients with persistent AF and mapped LVA > 5 cm2 after PVI, four variables-age ≥ 75 years, left atrial diameter > 44 mm, estimated glomerular filtration rate < 60 mL/min/1.73 m2, and absence of diabetes-were combined into the ALID score (0-4). Patients were stratified into low (0-1), intermediate (2), and high (3-4) score groups. Because EARNEST-PVI did not use LVA-guided ablation or select patients based on mapped LVA, it was analyzed as an exploratory supportive cohort rather than as an external validation cohort. RESULTS: In SUPPRESS-AF (n = 336), a significant treatment-by-score interaction was observed (P < 0.001). Adjunctive LVA ablation was associated with increased recurrence in the low-score stratum (HR 3.92; 95% CI 1.50-10.20) and reduced recurrence in the high-score stratum (HR 0.48; 95% CI 0.26-0.86). In EARNEST-PVI (n = 494), a qualitatively similar interaction pattern was observed for additional ablation beyond PVI (interaction P = 0.029), although the ablation strategy differed from LVA-guided ablation. CONCLUSIONS: Among patients with persistent AF and mapped LVA >5 cm2, the ALID score identified heterogeneity in response to adjunctive LVA ablation. These hypothesis-generating findings require prospective validation before clinical implementation.

Comparative evaluation of molecular technologies for the identification of prevalent non-tuberculous mycobacteria in pulmonary infections: a systematic review and meta-analysis.

BACKGROUND: The increasing prevalence of non-tuberculous mycobacteria pulmonary disease (NTM PD) is a burden to public health. Successful management of NTM PD critically depends on accurate species identification and reliable drug susceptibility testing to guide appropriate antibiotic therapy. Emerging molecular technologies offer rapid diagnostic solutions compared to conventional methods, but their performance varies. This study aims to provide a comprehensive evaluation of current molecular techniques for NTM identification and to present a global antibiotic resistance profile. METHODS: A systematic literature search was conducted in PubMed and Web of Science for studies published between 2005 and 2024. Studies applying molecular methods for NTM identification and resistance detection in humans were included. Data on study characteristics, diagnostic methods, sample types, sample sizes, identification sensitivity, and drug susceptibility results were extracted. Meta-analysis was performed using R with the meta4diag package. The quality of included studies was assessed using the QUADAS-2 tool. RESULTS: The analysis included 49 studies on NTM identification and 33 studies on antibiotic resistance. For species identification, all evaluated molecular technologies (MALDI-TOF MS, PCR-based methods, Sequencing, DNA chip, and DNA strip) demonstrated high pooled sensitivities (>0.92). Subgroup analysis revealed that sample type significantly affected performance for MALDI-TOF MS. Preliminary analysis of antibiotic resistance rates revealed varying patterns. For slowly growing mycobacteria, a significantly high Ethambutol resistance rate was observed in M. avium (69.20%). Among rapidly growing mycobacteria, resistance to Imipenem was notable (54.22%), and Clarithromycin resistance varied significantly within the Mycobacterium abscessus complex. CONCLUSION: Emerging molecular technologies have revolutionized the methodology for NTM identification with excellent performance. However, their performance can be influenced by sample type, particularly for MALDI-TOF MS. The alarming and heterogeneous antibiotic resistance patterns also highlight the critical need for rapid and accurate species identification and drug susceptibility testing to inform effective therapeutic strategies. Key messagesMolecular technologies demonstrate high accuracy for NTM identification.Antibiotic resistance is a serious concern with variations among NTM species and subspecies.Rapid and accurate species identification and drug susceptibility testing are crucial for guiding effective clinical management of NTM PD.

Targeting SIRT6: the design and therapeutic implications of activators and inhibitors.

Sirtuin 6 (SIRT6) is an NAD+-dependent deacylase that maintains genomic stability, regulates metabolism, and influences aging, making it an attractive but challenging therapeutic target. Pharmacological modulation of SIRT6 holds promise for cancer and metabolic disorders, yet its context-dependent functions demand precise intervention strategies. Potent, selective, and drug-like chemical probes are therefore essential to dissect SIRT6 biology and to validate its therapeutic potential. This review critically evaluates recent medicinal chemistry advances in SIRT6 modulation. We focus on structure-guided design strategies and structure-activity relationships (SAR) that have transformed initial hits into optimized leads for both activators and inhibitors, highlighting the remaining challenges in achieving isoform selectivity and drug-like properties.

Persistent cloaca without vaginal-common channel fistula: A Case series characterizing a rare phenotype.

INTRODUCTION: Persistent cloaca occurs in approximately 1 in 25,000 live births. Among patients with cloaca, the absence of a vaginal connection to the common channel represents a rare phenotype with distinct anatomic and management considerations. We describe the urologic, gynecologic, and surgical characteristics of this patient subset. METHODS: We performed a retrospective analysis of a single-institution cohort of patients with persistent cloaca managed at a quaternary-care children's hospital between 2019 and 2025. Patients were eligible if they underwent primary cloacal repair by our multidisciplinary team and met all three diagnostic criteria for absent vaginal-common channel fistula: no hydrocolpos on imaging, no identified vaginal opening on cystoscopy or cloacagram, and no visible lumen between müllerian and cloacal structures identified intraoperatively. RESULTS: Of 51 patients who underwent primary repair, 6 (12%) met criteria for absent vaginal-common channel fistula. All met criteria for VACTEGRLS association. Common channel length ranged from 1.1 to 7.0 cm and urethral length from 0.5 to 2.2 cm. Urologic anomalies were nearly universal: five patients (83%) had a solitary functional kidney and four (67%) had vesicoureteral reflux. All underwent posterior sagittal anorectoplasty (PSARP) for rectal repair with the common channel repurposed as the neourethra. Five (83%) underwent diagnostic laparoscopy during which the müllerian structures were examined but left in situ. At last follow-up (median 17.5 months, range 4-35 months), three patients (50%) had volitional voiding and three (50%) required assisted bladder emptying via vesicostomy or Mitrofanoff. CONCLUSION: Persistent cloaca without a vaginal-common channel fistula represents a rare but clinically distinct phenotype characterized by severe urologic anomalies. Recognition of this phenotype is essential for surgical planning and long-term urologic and gynecologic surveillance. Because there was no connection between the vagina and the urinary tract, delaying management of the müllerian structures did not adversely affect the urinary tract.

Cost-Effectiveness and the Economics of Genomic Testing and Molecularly Matched Therapies.

Cost-effectiveness analysis of precision oncology can help guide value-driven care. Next-generation sequencing is increasingly cost-efficient over single gene testing because diagnostic algorithms require multiple individual gene tests to determine biomarker status. Matched targeted therapy is often not cost-effective due to the high cost associated with drug treatment. However, genomic profiling can promote cost-effective care by identifying patients who are unlikely to benefit from therapy. Additional applications of genomic profiling such as universal testing for hereditary cancer syndromes and germline testing in patients with cancer may represent cost-effective approaches compared with traditional history-based diagnostic methods.

Autologous bone grafts versus alloplastic implants for orbital floor reconstruction: a systematic review and meta-analysis.

PURPOSE: The choice of reconstructive material for orbital floor fractures remains a subject of debate. While autologous bone has historically been considered the "gold standard," alloplastic implants offer potential advantages in reducing surgical morbidity. This meta-analysis aimed to compare the safety and efficacy of autologous bone grafts versus alloplastic implants in orbital floor reconstruction. METHODS: A systematic review was conducted in accordance with PRISMA guidelines (PROSPERO: CRD420251140583). Electronic databases (PubMed, Scopus, Web of Science, Cochrane Library) were searched from inception to August 2025. Randomized controlled trials and comparative cohort studies evaluating functional outcomes (diplopia, enophthalmos) and complications (ectropion, infection, malposition) were included. Data were synthesized using a random-effects model, with risk ratios (RR) and 95% confidence intervals (CI) calculated. RESULTS: Twenty studies comprising 2,119 patients were included. Alloplastic implants demonstrated statistically significant superiority in periocular safety, with a reduced risk of postoperative ectropion compared to autologous grafts (RR = 2.245; p = 0.020). In an exploratory sensitivity analysis excluding one outlier study, autologous grafts were associated with a significantly higher risk of implant malposition (RR = 2.074; p = 0.004). Autologous reconstruction was associated with a strong trend toward increased postoperative pain (p = 0.052) and inherent donor-site morbidity. No statistically significant differences were observed regarding infection (p = 0.402), enophthalmos (p = 0.201), or diplopia (p = 0.221). CONCLUSION: Alloplastic implants were associated with a lower risk of ectropion and implant malposition, with functional outcomes statistically comparable to autologous bone. Given the elimination of donor-site morbidity, alloplastic biomaterials represent a safe and effective alternative for orbital floor reconstruction; however, the predominance of retrospective, heterogeneous studies in the current evidence base means these findings should inform, rather than replace, individualized surgical decision-making pending further high-quality randomized trials.

Gubernacular discontinuity and abnormal distal fixation in cryptorchidism: Challenging the classical concept.

BACKGROUND: The gubernaculum is essential for testicular descent, but its detailed surgical anatomy remains poorly understood. We have previously identified an unrecognized anatomy of the round ligament in female patients with sliding inguinal hernias. OBJECTIVE: This study investigated whether comparable anatomical features exist in the gubernaculum of male cryptorchidism patients, as compared to those identified in female sliding hernias. MATERIALS AND METHODS: We retrospectively analyzed undescended testes located in the inguinal canal that underwent open inguinal orchidopexy between 2016 and 2025. Laparoscopically managed nonpalpable testes and those with suprascrotal testes were excluded. To ensure consistent anatomical evaluation, a standardized surgical protocol supervised by the senior author was applied to all cases. Findings were verified using operative reports and video recordings. After dissecting the processus vaginalis along the internal spermatic fascia (transversalis fascia), the pars infravaginalis gubernaculi were exposed. The relationship between the plica gubernaculi and pars infravaginalis gubernaculi, as well as the site of distal gubernacular fixation, was assessed. RESULTS: A total of 64 undescended testes of 56 patients were included. Video recordings were available for 45 of these 64 testes (70%). A patent processus vaginalis was observed in 60 out of 64 testes (94%), while it was obliterated in two ascending testes and unknown in two. In all 64 testes (100%), the pars infravaginalis gubernaculi was not continuous with the plica gubernaculi, with the transversalis fascia interposed between them. This configuration closely resembled that described previously for sliding inguinal hernias in women. Distal gubernacular fixation was located lateral to the scrotum in 49 testes (77%), at the upper scrotal border in 14 testes (22%), and absent in one testis (1.6%). DISCUSSION: Cryptorchidism is associated with a previously unrecognized discontinuity of the gubernaculi and common abnormal distal gubernacular fixation. These findings challenge the conventional views on gubernacular invagination and suggest that abnormal distal fixation may contribute to failed testicular descent. The study was limited by its single-center, retrospective design, small sample size, and lack of a control group. CONCLUSION: This study identified a previously unrecognized discontinuity of the gubernaculi in cryptorchidism. These findings deepen the understanding of the pathophysiology of testicular descent.

Older adults with resectable gastric cancer undergoing perioperative chemotherapy or preoperative chemoradiotherapy plus perioperative chemotherapy: A secondary analysis of the AGITG TOPGEAR phase III trial.

PURPOSE: To evaluate treatment adherence, adverse events, and survival in older (≥70 years) adults undergoing perioperative treatment for gastric cancer. METHODS: Patients with resectable gastric/gastro-esophageal junction adenocarcinoma (ECOG 0-1) enrolled in the phase III TOPGEAR trial were randomized to perioperative chemotherapy (ECF/ECX or FLOT) alone or perioperative chemotherapy plus preoperative chemoradiotherapy (45 Gy in 25 fractions with concurrent fluoropyrimidine). In this exploratory analysis, treatment completion, grade ≥ 3 adverse events (CTCAE v3.0), surgical outcomes, overall survival (OS) and progression-free survival (PFS) were compared between older and younger adults. RESULTS: Of the 574 patients enrolled, 135 (24%) were ≥ 70 years. Older adults more frequently required preoperative chemotherapy dose reductions, omissions, or delays (chemoradiotherapy: 55% vs 35%, p = 0.004; chemotherapy: 60% vs 48%, p = 0.087). Rates of grade ≥ 3 adverse events were comparable between older and younger patients (chemoradiotherapy: 66% vs 67%, p = 0.874; chemotherapy: 68% vs 59%, p = 0.220), but older adults more often had hematologic toxicity and grade ≥ 3 diarrhea in the chemotherapy group (56% vs 37%, p = 0.006; 21% vs 6%, p < 0.001). Resection rates, grade 3/4 surgical complications, number of removed lymph nodes, and 30-/90-day mortality were similar by age. OS and PFS were comparable across age groups, with numerically favorable outcomes for older adults (OS: HR 0.86, 95% CI 0.58-1.26 [chemoradiotherapy]; HR 0.75, 95% CI 0.51-1.11 [chemotherapy]; PFS: HR 0.78, 95% CI 0.53-1.15 [chemoradiotherapy]; HR 0.70, 95% CI 0.47-1.03 [chemotherapy]). CONCLUSIONS: Older adults with gastric cancer achieved comparable oncologic outcomes to younger patients, despite more frequent treatment modifications and higher hematologic toxicity.

No Efficacy of Dexamethasone Injections for Acute Sciatica: A Double-Blind Randomized Study Versus Saline.

BACKGROUND: The efficacy of caudal injections for patients with acute sciatica remains controversial. The DEXHIA study was designed to evaluate whether ultrasound-guided caudal injection of dexamethasone provides superior clinical outcomes compared with saline placebo. METHODS: This prospective, randomized, placebo-controlled, double-blind trial included adult patients with sciatica secondary to lumbar disc herniation of less than 3 months' duration. Participants were randomly assigned in a 1:1 ratio to receive either 16 mg of dexamethasone (4 mL) diluted with 16 mL of saline (DEXA group) or 20 mL of saline alone (PLACEBO group), administered by ultrasound-guided caudal epidural injection. The primary outcome was the change in the Oswestry Disability Index (ODI) at 3 weeks. Secondary outcomes included leg pain and low back pain assessed by visual analogue scale (VAS), health-related quality of life (SF-36), need for repeat epidural injection, and need for lumbar surgery. Clinical assessments were performed at 3 weeks, 3 months, and 6 months. RESULTS: A total of 106 patients were randomized, with 53 participants assigned to each treatment group. The primary endpoint was not met, as the improvement in ODI at 3 weeks did not differ significantly between groups (mean change: -9.5 ± 4.4 in the DEXA group versus -13.8 ± 4.4 in the PLACEBO group; p = 0.18). No significant differences were observed for any relevant secondary outcome at any follow-up time point. During the 6-month follow-up, 34 patients in the DEXA group and 30 patients in the PLACEBO group underwent a second, non-blinded injection of dexamethasone (ns). Lumbar surgery was performed in 10 patients in the DEXA group and nine patients in the PLACEBO group (ns). Injection-related adverse events were mild and transient but occurred more frequently in the DEXA group. CONCLUSIONS: Caudal injection of soluble dexamethasone conferred no clinical benefit over saline placebo in patients with acute sciatica. SIGNIFICANCE STATEMENT: Epidural injections are widely used worldwide for the treatment of resistant sciatica and have been extensively studied in multiple meta-analyses. However, their clinical value remains debated due to the limited methodological quality of most available studies. We conducted a methodologically rigorous randomized, placebo-controlled trial, which yielded negative results. These findings question the efficacy of caudal epidural injection of a non-particulate corticosteroid administered via a remote (sacrococcygeal) approach for disc-related sciatica. TRIAL REGISTRATION: The trial was registered under European Clinical Trials No. 2021-001571-17 and ClinicalTrials.gov identifier NCT05000658.

Emotional and Cognitive Processes Underlying Persuasion, Moderating Factors, and Physiological Reactions: A Systematic Review.

Persuasion is a type of social influence aiming to produce changes in others' attitudes or behaviors. This study explores the relationship between emotions and persuasion, principal moderating factors, and physiological reactions during persuasive attempts. Following PRISMA guidelines, 28 empirical articles were analyzed, addressing emotions, affective/cognitive orientations, framing effects, and psychophysiological reactions. Mixed findings emerged regarding emotions, with fear appeals being effective in health education, while more recent studies favor the use of positive persuasive messages to increase behavior intention. Principal moderating factors included personal relevance, need for cognition (NFC) and need for affect (NFA), thought confidence, vulnerability, and efficacy beliefs. Psychophysiological studies revealed distinct physiological arousal during persuasion processing compared to a rest state. In addition, a greater misalignment between current behavior and the persuasive attempt led to perceived freedom threat and psychological reactance. These insights enhance persuasive effectiveness and deepen understanding of persuasion processes, guiding future research directions.
