Objective:To explore the application strategies and clinical effects of superior gluteal artery perforator tissue flaps in repairing stage Ⅳ pressure ulcers in the sacrococcygeal region.Methods:This study was a retrospective observational study. From July 2019 to April 2024, 89 patients with stage Ⅳ pressure ulcers in the sacrococcygeal region who met the inclusion criteria were admitted to the First Affiliated Hospital of Nanchang University, including 59 males and 30 females, aged 21 to 84 years. There were 89 sacrococcygeal pressure ulcers, with an area of 5.0 cm×4.0 cm-21.0 cm×21.0 cm after debridement. According to the shape, size, and depth of the wounds after debridement, combined with the elasticity and texture of the skin around the wounds, and the principle of minimizing damage to the donor area, the appropriate forms of superior gluteal artery perforator tissue flaps were cut for wound repair in the following three conditions. (1) For wounds with a round shape, an area of 5.0 cm×5.0 cm-21.0 cm×21.0 cm, and a depth of 1.0-3.5 cm, the superior gluteal artery perforator propeller flap or myocutaneous flap, bilobed superior gluteal artery perforator relay flap, and bilateral superior gluteal artery perforator rotational flap were used. (2) For wounds with an oval shape, an area of 5.0 cm×4.0 cm-18.5 cm×10.5 cm, and a depth of 1.0-3.0 cm, the superior gluteal artery perforator propeller flap or myocutaneous flap, unilateral superior gluteal artery perforator propeller flap combined with contralateral superior gluteal artery perforator V-Y advanced flap or keystone flap were used. (3) For wounds with a fusiformis shape, an area of 7.0 cm×4.0 cm-17.5 cm×6.0 cm, and a depth of 1.5-5.0 cm, the unilateral or bilateral superior gluteal artery perforator V-Y advanced flap, superior gluteal artery perforator keystone flap, or superior gluteal artery perforator keystone flap combined with gluteus maximus muscle flap were used. In this group of patients, a total of 40 superior gluteal artery perforator propeller flaps (with an resection area of 11.0 cm×6.0 cm-17.0 cm×11.0 cm), 22 superior gluteal artery perforator propeller myocutaneous flaps (with an resection area of 10.0 cm×5.0 cm-14.0 cm×8.0 cm), 7 bilobed superior gluteal artery perforator relay flaps (with a main flap resection area of 5.5 cm×5.5 cm-18.0 cm×11.5 cm and a side flap resection area of 4.5 cm×3.0 cm-11.0 cm×6.5 cm), 5 bilateral superior gluteal artery perforator rotational flaps (with a total resection area of 20.0 cm×16.0 cm-26.0 cm×21.0 cm on both sides), 14 superior gluteal artery perforator V-Y advanced flaps (with an resection area of 12.0 cm×10.0 cm-18.0 cm×18.0 cm), 13 superior gluteal artery perforator keystone flaps (with an resection area of 13.0 cm×6.5 cm-19.0 cm×18.0 cm), and 3 gluteus maximus muscle flaps (with an resection area of 8.0 cm×3.0 cm-15.0 cm×4.5 cm). The donor area wounds were all directly sutured. The survival of tissue flaps was observed and the incidence rate of delayed wound healing in the reception area was calculated, and wound healing in the donor area was observed. The appearance and texture of tissue flaps and recurrence of pressure ulcers were followed up.Results:After surgery, all bilateral superior gluteal artery perforator rotational flaps, superior gluteal artery perforator V-Y advanced flaps, superior gluteal artery perforator keystone flaps, and gluteus maximus muscle flaps survived well. There were 6 cases of delayed wound healing in the reception area after surgery, with an incidence rate of 6.7% (6/89). Two patients had incision dehiscence in the donor area wounds due to postoperative bleeding, the wounds healed after debridement, vacuum sealing drainage, and dressing change. The wounds in the donor area of the remaining patients healed well. Six patients were lost to follow-up. Eighty-three patients were followed up for 3-48 months, of whom 4 patients died. Among the remaining 79 patients, 3 cases had pressure ulcers recur due to improper nursing, while the rest of the patients had tissue flaps with good appearance and soft texture and no recurrence of pressure ulcers.Conclusions:Based on the characteristics of wound shape, size, and depth after debridement of stage Ⅳ pressure ulcers in the sacrococcygeal region, individualized selection of flap, myocutaneous flap, or a combination of flap and gluteus maximus muscle flap based on the perforating branch of the superior gluteal artery perforator can achieve good clinical repair results. The postoperative tissue flap survived well, with a good appearance, soft texture, and less recurrence of pressure ulcers.

OBJECTIVE: To evaluate the dynamic changes of glucocorticoid (GC) dose and the feasibility of GC discontinuation in rheumatoid arthritis (RA) patients under the background of Chinese medicine (CM). METHODS: This multicenter retrospective cohort study included 1,196 RA patients enrolled in the China Rheumatoid Arthritis Registry of Patients with Chinese Medicine (CERTAIN) from September 1, 2019 to December 4, 2023, who initiated GC therapy. Participants were divided into the Western medicine (WM) and integrative medicine (IM, combination of CM and WM) groups based on medication regimen. Follow-up was performed at least every 3 months to assess dynamic changes in GC dose. Changes in GC dose were analyzed by generalized estimator equation, the probability of GC discontinuation was assessed using Kaplan-Meier curve, and predictors of GC discontinuation were analyzed by Cox regression. Patients with <12 months of follow-up were excluded for the sensitivity analysis. RESULTS: Among 1,196 patients (85.4% female; median age 56.4 years), 880 (73.6%) received IM. Over a median 12-month follow-up, 34.3% (410 cases) discontinued GC, with significantly higher rates in the IM group (40.8% vs. 16.1% in WM; P<0.05). GC dose declined progressively, with IM patients demonstrating faster reductions (median 3.75 mg vs. 5.00 mg in WM at 12 months; P<0.05). Multivariate Cox analysis identified age <60 years [P<0.001, hazard ratios (HR)=2.142, 95% confidence interval (CI): 1.523-3.012], IM therapy (P=0.001, HR=2.175, 95% CI: 1.369-3.456), baseline GC dose ⩽7.5 mg (P=0.003, HR=1.637, 95% CI: 1.177-2.275), and absence of non-steroidal anti-inflammatory drugs use (P=0.001, HR=2.546, 95% CI: 1.432-4.527) as significant predictors of GC discontinuation. Sensitivity analysis (545 cases) confirmed these findings. CONCLUSIONS RA patients receiving CM face difficulties in following guideline-recommended GC discontinuation protocols. IM can promote GC discontinuation and is a promising strategy to reduce GC dependency in RA management. (Trial registration: ClinicalTrials.gov, No. NCT05219214).

Objective:To explore the possibility of using a inferior gluteal artery perforator flap (IGAPF) for breast reconstruction in the patient who did not have suitable donor site in back and abdomen.Methods:In November 2024, a 25-year-old unmarried and childless woman with right breast cancer received immediate right breast reconstruction by a right free IGAPF after modified right mastectomy in the Department of Breast and Thyroid Surgery, Second Affiliated Hospital of Hainan Medical University. The locations of perforators were confirmed by both Multi-detector computed tomography angiography (MDCTA) and portable Doppler blood flow detector before surgery. The IGAPF was designed to take the inferior gluteal wrinkle as the lower edge, the axis of the flap was parallel to the inferior gluteal wrinkle, and the width of the flap was estimated where the incision could be directly closed. The size of right IGAPF was 6.0 cm×19.0 cm. Sharp dissection was performed between the sarcolemma and muscle fibres of gluteus, then the perforators were dissected along the direction of muscle fibres of gluteus. The vascular pedicle was kept at about 8.0 cm in length. The diameter of artery was about 2.0 mm and that for the veins was about 1.5 mm. End-to-end anastomoses with the right thoracodorsal artery and vein were successfully carried out. The donor site was directly closed, and it was hidden in the inferior gluteal wrinkle. Postoperative outpatient clinical review was made.Results:Pathological examination reported: an invasive carcinoma of right breast, axillary lymph node metastasis (2/10). The patient recovered well and the flap survived without any complication, i.e. ischemic necrosis, infection and haematoma. The patient was off-bed at 3 days and discharged at 13 days after surgery. At the 40 days of postoperative follow-up, the patient achieved a good recovery and the lower limb activity was not affected by the surgery. The patient was satisfied with the reconstructed breast and donor site recovery. The patient followed with scheduled chemotherapy and subsequent radiotherapy. The volume of reconstructed breast was smaller than the other breast, of which the patient was fully informed before the surgery.Conclusion:A free IGAPF provides an alternative donor sites for achieving a breast reconstruction due to the reliable pedicle vessels and invisible donor scars.

Objective:To investigate the impact of early invasive arterial blood pressure (IBP) monitoring on survival and neurological outcomes in out-of-hospital cardiac arrest (OHCA) patients undergoing extracorporeal cardiopulmonary resuscitation (ECPR).Methods:This retrospective cohort study analyzed 44 OHCA patients receiving ECPR between January 2021 and January 2023. Patients were divided into: Early intervention group : IBP established within 3 min of ECMO initiation; Late intervention group : IBP established after ICU admission. Baseline characteristics, ECMO parameters, and clinical outcomes were compared. Multivariable logistic regression (adjusted for age, initial rhythm, etc.) and Spearman's correlation were used.Results:This study included a total of 44 patients treated with OHCA and ECPR, divided into an early intervention group of 23 cases and a late intervention group of 21 cases. The early intervention group showed significantly higher: Survival to discharge (43.5% vs. 9.5%, P<0.05), Good neurological recovery (CPC 1-2: 34.8% vs. 9.5%, P<0.05).Early intervention independently predicted survival (adjusted OR=18.84, 95% CI:1.97-179.98, P=0.01). Stratified analysis by pH (cutoff 7.0) demonstrated consistent benefits in both pH>7.0 ( aOR=0.392, 95% CI:0.106-0.678) and pH≤7.0 subgroups ( aOR=0.385, 95% CI: 0.075-0.695; interaction P=0.183). Early IBP positively correlated with CPC scores ( ρ=0.40, P=0.007). Conclusions:Early IBP monitoring significantly improves survival and neurological outcomes in OHCA-ECPR patients, supporting its integration into standardized protocols.

BACKGROUND: While emotional distress, encompassing anxiety and depression, has been associated with negative clinical outcomes, its impact across various clinical departments and general hospitals has been less explored. Previous studies with limited sample sizes have examined the effectiveness of specific treatments (e.g., antidepressants) rather than a systemic management strategy for outcome improvement in non-psychiatric inpatients. To enhance the understanding of the importance of addressing mental health care needs among non-psychiatric patients in general hospitals, this study retrospectively investigated the impacts of emotional distress and the effects of early detection and management of depression and anxiety on hospital length of stay (LOS) and rate of long LOS (LLOS, i.e., LOS >30 days) in a large sample of non-psychiatric inpatients. METHODS: This retrospective cohort study included 487,871 inpatients from 20 non-psychiatric departments of a general hospital. They were divided, according to whether they underwent a novel strategy to manage emotional distress which deployed the Huaxi Emotional Distress Index (HEI) for brief screening with grading psychological services (BS-GPS), into BS-GPS ( n = 178,883) and non-BS-GPS ( n = 308,988) cohorts. The LOS and rate of LLOS between the BS-GPS and non-BS-GPS cohorts and between subcohorts with and without clinically significant anxiety and/or depression (CSAD, i.e., HEI score ≥11 on admission to the hospital) in the BS-GPS cohort were compared using univariable analyses, multilevel analyses, and/or propensity score-matched analyses, respectively. RESULTS: The detection rate of CSAD in the BS-GPS cohort varied from 2.64% (95% confidence interval [CI]: 2.49%-2.81%) to 20.50% (95% CI: 19.43%-21.62%) across the 20 departments, with a average rate of 5.36%. Significant differences were observed in both the LOS and LLOS rates between the subcohorts with CSAD (12.7 days, 535/9590) and without CSAD (9.5 days, 3800/169,293) and between the BS-GPS (9.6 days, 4335/178,883) and non-BS-GPS (10.8 days, 11,483/308,988) cohorts. These differences remained significant after controlling for confounders using propensity score-matched comparisons. A multilevel analysis indicated that BS-GPS was negatively associated with both LOS and LLOS after controlling for sociodemographics and the departments of patient discharge and remained negatively associated with LLOS after controlling additionally for the year of patient discharge. CONCLUSION Emotional distress significantly prolonged the LOS and increased the LLOS of non-psychiatric inpatients across most departments and general hospitals. These impacts were moderated by the implementation of BS-GPS. Thus, BS-GPS has the potential as an effective, resource-saving strategy for enhancing mental health care and optimizing medical resources in general hospitals.

Objective:Explore the feasibility and advantages of using proximal and distal ends of thoracodosal artery and vein as recipient vessels in deep inferior epigastric perforator flap immediate breast reconstruction.Methods:The clinical data of patients who underwent breast reconstruction surgery using the proximal and distal ends of the thoracodorsal vein as recipient vessels at the Department of Breast and Thyroid Surgery of the Second Affiliated Hospital of Hainan Medical University from March 2022 to June 2023 were analyzed retrospectively. Preoperative examinations included thoracoabdominal angiography and color Doppler ultrasonic localization of the main trunk and perforators of the inferior epigastric vessels. The procedure began with mastectomy and axillary lymph node dissection, followed by the isolation of bilateral perforators and the main trunk of the abdominal flap. The main trunks of the bilateral inferior epigastric arteries were then transected, and their vascular pedicles exposed and anastomosed respectively to the proximal and distal ends of the thoracodorsal artery and vein. Both arteries and veins were joined end-to-end. The flap after trimming and reconstruction was then implanted into the cavity left after mastectomy through the incision. Breast positioning was performed with the patient in a knee-bent and hip-flexed position. After adjusting the shape of the reconstructed breast. The donor site was closed, the umbilicus was reconstructed, drainage tubes were placed, and the breast incision was closed. Postoperative follow-up monitored complications associated with the flap and patient satisfaction with the breast reconstruction, utilizing a self-assessment method.Results:Four female patients were included, aged (46.0±6.5) years, ranging from 37 to 52 years. All four patients had bilateral vascular pedicles in the donor area, with three patients having thoracodorsal vessels at the distal and proximal ends as recipient vessels, and one patient having anterior serratus branch of the thoracodorsal vessels at the distal and proximal ends. All drainage tubes were removed within 7 to 10 days after surgery. Patients were discharged. Follow-up period ranged from 1 to 15 months, averaging 6 months. The patients recovered well postoperatively, with no flap-related complications occurring. All four patients were satisfied with the result of the reconstruction.Conclusion:The simultaneous application of the proximal and distal ends of the thoracodorsal artery and vein can ensure the safety of flap survival while reducing damage to the ribs and intercostal muscles, achieving better aesthetic result.
