Objective: To characterize perioperative dynamic changes in immune-cell phenotypes and inflammatory cytokines in patients undergoing CPB (cardiopulmonary bypass) cardiac surgery, and to explore their associations with postoperative outcomes. Methods: In this prospective cohort study, 120 adult patients who underwent elective cardiac surgery under CPB at West China Hospital from May 2022 to March 2023 were enrolled. Perioperative immune-cell phenotypes and concentrations of 40 inflammation-related cytokines were measured. The primary outcomes were the sequential organ failure assessment (SOFA) score at 24 h after surgery and ΔSOFA (the peak SOFA score within 48 h after surgery minus the preoperative SOFA score). Secondary outcomes included major adverse cardiovascular events (MACE), acute kidney injury (AKI), respiratory failure, severe liver injury, and infection. Results: The mean age of enrolled patients was 57±10 years. Of these, 52% (62/120) were male and 90% (108/120) underwent valve surgery. During the rewarming to the end of CPB, neutrophil counts rapidly increased (7.39×10
/L vs preoperative 3.07×10
/L, P<0.001), with significant upregulation of CD11b (7.30×10
/L vs preoperative 3.05×10
/L, P<0.001) and CD54 (7.15×10
/L vs preoperative 2.99×10
/L, P<0.001). Lymphocyte counts increased at the end of CPB (1.75×10
/L vs preoperative 1.12×10
/L, P<0.001) but decreased significantly at 24 h after surgery (0.59×10
/L vs preoperative 1.12×10
/L, P<0.001). Plasma analysis showed that multiple pro-inflammatory cytokines increased during CPB and remained elevated up to 24 h after surgery; five chemokines and the anti-inflammatory cytokine IL-10 peaked at the end of CPB. The SOFA score increased from 1 (1, 2) preoperatively to 7 (5, 10) at 24 h after surgery, with a ΔSOFA of 6 (4, 8). Within 30 days after surgery, 48 patients (40.0%) developed AKI, 17 (14.2%) developed infection, 4 (3.3%) developed severe liver injury, 3 (2.5%) developed respiratory failure, and 3 (2.5%) experienced MACE. During the 2-year follow-up, 8 patients (6.7%) experienced MACE and 5 (4.2%) died. Conclusion: Multi-organ dysfunction is common after cardiac surgery under CPB (median ΔSOFA, 6), accompanied by perioperative activation of multiple immune-cell subsets and upregulation of pro-inflammatory, anti-inflammatory, and chemotactic mediators. This study provides data-driven evidence and research clues for further investigation of the associations between CPB-related immune perturbations and postoperative organ dysfunction and clinical outcomes.

Robotic-assisted pedicle screw placement and full-endoscopic transforaminal lumbar interbody fusion (FE-TLIF) are established minimally invasive spine techniques. Their integration has the potential to combine navigation accuracy with the muscle-preserving advantages of uniportal endoscopy. This technical note describes a hybrid approach using the Mazor X Stealth edition robotic system to enhance workflow, safety, and efficiency during FE-TLIF. A 74-year-old patient with metabolic syndrome presented with severe back and radicular leg pain that was refractory to conservative treatment. Magnetic resonance imaging demonstrated bilateral lateral recess stenosis, disc height loss, and facet arthropathy at L4–5, with dynamic instability observed on flexion-extension radiographs. Preoperative computed tomography imaging was uploaded to the robotic system for trajectory planning. Following registration, the robotic arm guided percutaneous pedicle screw placement via Wiltse incisions. Uniportal endoscopic access enabled hemilaminotomy, facetectomy, discectomy, endplate preparation, and insertion of an expandable L4–5 interbody cage under direct visualization. Robotic guidance facilitated precise screw trajectory placement without repeated fluoroscopic localization, reduced intraoperative radiation exposure, and avoided muscle disruption associated with open approaches. Endoscopic visualization enabled controlled facet resection and preservation of neural elements during cage placement. Postoperative radiographs confirmed appropriate implant positioning. The combined workflow improved surgical ergonomics and minimized tissue trauma while maintaining fusion stability. Robotic-assisted FE-TLIF represents a safe and feasible hybrid minimally invasive surgery technique that enhances pedicle screw accuracy and complements endoscopic fusion. Despite a steep learning curve, this approach may reduce perioperative morbidity, improve procedural efficiency, and enhance postoperative recovery. Further comparative studies are required to evaluate long-term clinical and radiographic outcomes.

Objective:
Spinal stenosis and degenerative spinal disorders are increasingly prevalent and have a substantial impact on quality of life. Surgical decompression, performed using either open microscopic or endoscopic approaches, remains a cornerstone of management for these conditions. This study examines evolving trends in single-level lumbar spinal decompression procedures performed at a tertiary academic hospital in Singapore.
Methods:
A retrospective observational study was conducted involving 588 patients who underwent single-level spinal decompression between 2021 and 2024, including endoscopic spine surgery (ESS; n=364) and microdecompression (n=224). Primary outcome measures were changes in 36-Item Short Form Health Survey (SF-36) and visual analogue scale (VAS) scores at 3 months, 6 months, and 2 years postoperatively. Secondary outcomes included length of hospital stay, reoperation rates, and operative time. Patient demographics, spinal level and pathology characteristics, surgical techniques, and postoperative outcomes were analyzed. Difference-in-differences (DID) analysis was used to compare outcomes between the 2 groups.
Results:
Both groups demonstrated significant postoperative improvements in SF-36 and VAS scores. At 2 years, Short Form Health Survey physical function (SFPF) scores improved in the endoscopic group (mean difference [MD], 18.6; standard deviation [SD], 21.7; p=0.064) and in the open microscopic group (MD, 36.7; SD, 20.9; p=0.007), with a non-significant DID of -18.1 (p=0.155). No DID comparisons across SF-36 domains reached statistical significance. Mean operative time for endoscopic procedures decreased from 249 minutes in 2022 to 145 minutes in 2024, reflecting a procedural learning curve. Surgeons with higher endoscopic caseloads exhibited greater improvements in functional outcomes.
Conclusion
Both endoscopic and open microscopic decompression achieve comparable short- and long-term clinical outcomes. ESS provides similar effectiveness while being associated with shorter recovery periods and reduced hospital stay. Further research is warranted to identify factors contributing to incomplete symptom resolution or the need for revision surgery.

Despite of the widespread use of hydrogen and methane breath test, the variability in testing protocols, gas measurement techniques, and interpretation criteria continues to challenge the reproducibility and comparability across centers, especially in the Asia-Pacific region. The Asian Neurogastroenterology and Motility Association hence presents the first Asian monograph guiding application and interpretation of breath test. The monograph was formulated according to the framework of indications, preparatory process, performance, and interpretation of results, as well as future direction for research.

Introduction:
Large, rapidly enlarging adrenal masses typically mandate
surgical intervention given the high probability of adrenocortical carcinoma (ACC). However, benign processes can mimic these aggressive growth kinetics, creating a
diagnostic challenge for clinicians.
Case:
A 74-year-old male with hypertension, atrial fibrillation on
rivaroxaban, and prostate cancer was referred for evaluation
of a right adrenal incidentaloma detected on computed
tomography imaging performed for prostate cancer
staging. The well-defined mass measured 8.9 × 7.8 × 7.5 cm
(AP × W × CC) with areas of calcification. Mean attenuation
was +40 Hounsfield Unit, with no significant washout.
Biochemical evaluation confirmed a non-functioning
lesion (24-hour urine metanephrines 756 mcg/24 hours
[N 246–753 mcg/24 hours]; serum cortisol 62 nmol/L post
overnight dexamethasone suppression test). The patient was otherwise asymptomatic and declined surgical intervention. Repeat imaging 4 months later demonstrated
interval enlargement of the mass to 9.8 × 8.8 × 10.7 cm. Due
to this rapid growth, which was highly concerning for ACC,
the patient underwent laparoscopic right adrenalectomy.
Histopathological examination unexpectedly revealed
an adrenal hematoma without evidence of an underlying
tumor or malignancy.
This case illustrates the difficulty in differentiating
aggressive cortical tumors from atypical hemorrhagic
events. Larger series on adrenal hemorrhage reported
trauma and procedural complications as the leading causes,
with a median size of 3–4 cm. Idiopathic large adrenal
hematomas presenting as rapidly expanding “pseudotumors” are exceptionally rare, with fewer than 20 cases
reported in which surgical resection was performed due to
high preoperative suspicion of malignancy. Additionally,
adrenal hemorrhage attributed to anticoagulant therapy
often occurs bilaterally. Unilateral lesion, especially when
large, can pose a diagnostic challenge as highlighted in
this case.
Conclusion
In patients on anticoagulation, rapid interval growth of
an adrenal mass does not always equate to malignancy.
Recognizing this mimicry in the era of widespread Direct
Oral Anticoagulant use is essential for refining treatment
decision regarding surgical intervention, as most cases exhibited a self-limiting process with spontaneous resolution.

ObjectiveMigraine is a leading neurological disorder and the fourth most common cause of years lived with disability worldwide, affecting nearly 116 million individuals. Although pharmacological treatments are available, their efficacy is often limited by side effects and variable response rates. Repetitive transcranial magnetic stimulation (rTMS) over the dorsolateral prefrontal cortex (DLPFC) offers a safe, non-invasive alternative for migraine management. However, the neurophysiological mechanisms, particularly how rTMS modulates local cortical excitability and distributed pain-related circuits, remain poorly understood. Elucidating these mechanisms is essential for optimizing treatment protocols and improving clinical outcomes. MethodsThis study employed concurrent transcranial magnetic stimulation and electroencephalography (TMS-EEG) to investigate neuroplastic and neurocircuitry mechanisms of DLPFC-rTMS in migraine. Study 1 compared 30 migraineurs and 28 healthy controls to identify abnormalities in TMS-evoked potentials (TEPs) and significant current density (SCD) within sensory-discriminative regions including the primary somatosensory cortex (S1) and posterior insula (pINS), cognitive-affective regions including the anterior insula (aINS) and midcingulate cortex (MCC), and a descending modulatory region, the periaqueductal gray (PAG). Study 2 used a single-blind, crossover, sham-controlled design in 34 healthy participants. Each participant received both active (10 Hz, 80% RMT, 1 500 pulses) and sham DLPFC-rTMS in counterbalanced order. TMS-EEG and cold pain tolerance were assessed before and after each session. ResultsIn Study 1, migraineurs showed a significantly less negative N120 amplitude compared to healthy controls (P=0.027, Cohen’s d=0.60), indicating local intracortical disinhibition. No group differences were observed for N40, P60, or P180 components. At the source level, migraineurs exhibited significantly higher SCD in the S1, pINS, aINS, and MCC (allQ<0.05), but not in the ventroposterior thalamus (vpTHAL), mediodorsal thalamus (mdTHAL), or PAG. In Study 2, active rTMS significantly reduced SCD from pre- to post-stimulation in the S1, aINS, and MCC (all Q<0.05). Sham stimulation also reduced SCD in the S1 (Q<0.05) but not in the aINS or MCC. Although no significant group-level analgesic effect was observed between active and sham conditions (P=0.107), correlation analyses revealed that greater SCD reductions in the S1 and MCC were significantly associated with higher post-rTMS pain tolerance (R=-0.487 and -0.495, both Q<0.01) and larger improvements in pain tolerance(R=-0.487 and -0.451, both Q<0.05). No such correlations were found following sham stimulation, suggesting that the behavioural relevance of neural changes is specific to active rTMS. ConclusionThis study provides novel evidence that migraineurs exhibit both local neuroplastic abnormalities (reduced N120 amplitude) and hyperactivity in key pain-processing regions (S1, pINS, aINS, MCC). A single session of DLPFC-rTMS reduced hyperactivity in the aINS, MCC, and S1. Notably, greater reductions in the S1 and MCC were associated with improved pain tolerance. These findings identify distinct cortical circuitries, particularly within the cognitive-affective pain network, that may serve as potential biomarkers for optimizing rTMS treatment in migraine and other chronic pain conditions. Future studies should validate these results in patient populations experiencing spontaneous migraine attacks and explore multi-session or accelerated rTMS protocols.

Objective: To explore the possibility of performing allogeneic platelet-rich plasma (PRP) treatment for patients who were not suitable for autologous PRP collection through case reports of two patients with refractory wounds treated with allogeneic PRP. Methods: The ABO-compatible allogeneic whole blood was centrifuged 3 times to obtain allogeneic PRP within 6 hours of blood collection. Then the qualified allogeneic PRP was applied to 2 cases of refractory wound on the same day. Results: The platelet concentration in allogeneic PRP was higher than 1 000×10
/L, and the test results of infectious diseases, as well as the mixing of red blood cells and white blood cells, met the standard of quality control. Both patients achieved satisfactory wound healing outcomes (3 d). Conclusions: For patients who were not suitable for autologous PRP treatment, allogeneic PRP might be a new option.

Objective To explore the correlation between glycemic control and complexity of drug treatment regimens in elderly patients with type 2 diabetes mellitus.Methods A retrospective,cross-sectional study was conducted to collect the elderly patients with type 2 diabetes mellitus who were hospitalized in the Department of Endocrinology at the Geriatric Hospital of Nanjing Medical University from June 2022 to December 2024.The clinical characteristics and medication compliance of the patients were recorded through pharmaceutical consultations.The medication regimen complexity index(MRCI)and diabetes-specific medication regimen complexity index(D-MRCI)were calculated for each patient.Patients were divided into the target-achieving group and the non-target-achieving group based on whether their blood glucose met the criteria.Univariate analysis and multivariate Logistic regression analysis were used to identify the factors associated with adequate blood glucose control.Results A total of 152 patients were included,123(80.9%)had poorer glycemic control,31.6%exhibited good medication adherence,and 76.3%demonstrated good adherence to diabetes medications.The mean total MRCI score was(25.90±8.63),while the median D-MRCI score was 9.00(5.25,11.75),with 44.7%of patients classified as having high D-MRCI scores(D-MRCI>9).The results of Spearman correlation analysis indicated that the number of medications used by patients was highly correlated with the MRCI score(r=0.899,P<0.001),while the number of diabetes medications used was highly correlated with the D-MRCI score(r=0.705,P<0.001).Univariate analysis results revealed that high complexity diabetes medication regimen,duration of diabetes,the number of types of antidiabetic drugs,and the number of injectable antidiabetic medications were associated with glycemic control(P≤0.05).Multivariate analysis results showed that,high diabetes medication complexity was an independent risk factor for inadequate blood glucose control[OR=4.119,95%CI(1.121,15.139),P=0.033].Conclusion Higher D-MRCI(>9)was associated with poorer glycemic control.Simplifying medication regimens and optimizing medication management strategies may improve patient outcomes.
