Objective To study the prognosis and pre-procedural independent risk factors for pa-tients with no-reflow (NR) phenomenon during percutaneous coronary intervention (PCI). Methods Pa-tients with or without NR phenomenon during PCI procedures from January 2000 to January 2005 were studied retrospectively. The clinical data preoperative and the incidence of major adverse cardiovascular events (MACE) between the two groups were compared. Univariate analysis and multivariate Logistic analysis were used to select the risk factors for NR phenomenon. Retrospectively was reviewed for (35.8 ± 15.3)months. Results The NR group had more significant incidence of MACE. Multivariate Logistic analysis showed that the predictive factors for NR were (1) Smoke index ≥ 300(OR = 2.81,95%CI: 1.61-4.38 ,P =0.007). (2) Fasting blood glucose level before PCI ≥ 11.1 mmol/L (OR = 3.39,95%CI: 1.51-4.89,P = 0.000 ). (3) Absence of angina pectoris attack within one month before PCI (OR = 2.39,95%CI: 1.22-3.78,P = 0.009). Conclusions The prognosis is poor for the PCI patients with NR phenomenon. Those patients whose fasting blood glucose level before PCI ≥ 11.1 mm01/L, smoke index ≥ 300 and absence of angina pec-toffs attack within one month before PCI have higher incidence of NR phenomenon.

Objective: To evaluate the clinical and radiological outcomes,and the complications of staged minimally invasive surgery for adult degenerative scoliosis, comparing with that of the conventional open surgery. Methods: From Jun 2013 to Jun 2017, a total of 42 cases of degenerative scoliosis underwent surgical treatment. Among which, 23 cases underwent staged minimally invasive surgery(MIS group) and 19 cases underwent posterior open surgery(open group). The intra-operative bleeding, and operation time were recorded.The clinical outcomes were assessed using the Oswestry Disability Index (ODI), Visual Analogue Scale (VAS) for low back pain and leg pain.The radiological outcome was evaluated with Cobb angles and sagittal balance parameters (Sagittal Vertical Axis (SVA), Pelvic Incidence (PI)-Lumbar Lordosis (LL), Pelvic Tilt (PT)). The occurrence of complications was recorded. Results: The baseline demographic features of both groups (gender, age, medical comorbidity, etc.) were similar.The mean follow-up period for both groups was more than 2 years.The intraoperative bleeding in the MIS group 405.7±144.8 ml was significantly lower than that in the open group (2 005.3±728.4 ml, t=10.31, P<0.001); The total operation time 414.3±63.0 min of MIS group was significantly longer than that of the open group (304.2±51.8 min, t=6.10, P<0.001), but the operating time of each stage was shorter than the open group. The VAS score for back pain and leg pain,the ODI scores were significantly improved after surgery for both group, there was no significant difference between the two groups, but the low back pain and function in MIS group were better than the open group. The parameters of the coronal and sagittal deformity were significantly improved in both groups, correction of coronal deformity in MIS groupwassignificantly superior to the open group (F=12.02, P=0.001), there was no significant difference in sagittal balance correction between the two groups. The overall complication rate (63.2%) was slightly higher in the open group than in the MIS group (34.8%) without significant difference(χ²=3.36, P=0.07). The incidence of major complications in the open group was significantly higher than that in the MIS group (P=0.014). Conclusion Staged minimally invasive surgery can significantly relieve the patient's pain, improve functionand the coronal and sagittal balance of the patient, the early clinical and radiological outcomes were comparable to the open surgery; Minimally invasive surgery may significantly reduce the amount of bleeding and major complications. Minimally invasive surgery is safe and effective for carefully selected patients with degenerative scoliosis.However, the long-term outcomes of minimally invasive surgery remains to be followed up.

A 22-year-old female patient presented with skin flushing in the bilateral legs for 4 years, which gradually spread throughout the whole lower limbs and forearms 6 months ago. Skin examination showed diffuse flushing and dilated capillaries in the lower limbs and both forearms, and the flushing faded after a press. Histopathological examination of the skin lesion on the leg showed hyperkeratosis in a basket-like shape, increased pigmentation in the basal layer, infiltration of the superficial dermis with scattered lymphocytes, with no obvious red blood cell overflow; periodic acid-Schiff staining showed thickened and homogeneous deposits around the blood vessels; immunohistochemical staining showed thickened blood vessel walls and positive staining for type Ⅳ collagen. Diagnosis: cutaneous collagenous vasculopathy.

Objective:To investigate the factors contributing to frailty in very elderly patients with multimorbidity.Methods:This cross-sectional study enrolled 119 very elderly patients with multimorbidity who were hospitalized in the Department of Geriatrics of Huadong Hospital Affiliated to Fudan University from August 2022 to March 2023.The study aimed to understand the basic status of multimorbidity by collecting general information, the number and types of diseases, and frailty status.The subjects were divided into frail and non-frail groups through comprehensive geriatric assessment.Various factors including gender, age, Tinetti balance gait score, risk of sarcopenia, dementia, depression, risk of deep vein thrombosis, dysphagia, comorbidity index, medication count, Basic Activities of Daily Living(BADL)score, Instrumental Activities of Daily Living(IADL)score, Nutritional Risk Screening 2002(NRS-2002)score, Norton pressure injury risk assessment score, and Social Support Rating Scale(SSRS)score were compared.The correlation between each factor and the occurrence of frailty was analyzed using univariate analysis and multivariate Logistic regression analysis.Results:A total of 119 elderly inpatients with multimorbidity, with an average age of 90.8±5.9 years old, were included in the study.The incidence of frailty was 68.9%(82 cases).Univariate analysis revealed significant statistical differences between the frail group and the non-frail group in various factors including age( t=-3.131, P=0.002), Tinetti score( Z=-5.544, P<0.001), risk of sarcopenia( χ2=39.205, P<0.001), dysphagia( χ2=5.937, P=0.015), Charlson comorbidity index( Z=-2.565, P=0.010), medication count( Z=-3.325, P<0.001), BADL( Z=-5.871, P<0.001), IADL( Z=-5.062, P<0.001), Norton score( Z=-5.922, P<0.001), and SSRS social support( Z=-2.637, P=0.008).Multivariate logistic regression analysis showed that the Tinetti score( OR=0.843, 95% CI: 0.737-0.966, P=0.014), decreased muscle strength( OR=11.226, 95% CI: 2.157-58.432, P=0.004), sarcopenia( OR=18.084, 95% CI: 2.041-106.211, P=0.009), Norton score( OR=0.462, 95% CI: 0.254-0.838, P=0.011), and medication count( OR=1.153, 95% CI: 1.000-1.329, P=0.049)were independently associated with frailty. Conclusions:In very elderly patients with multimorbidities, the occurrence of frailty is notably increased.Frailty is linked to multiple risks including falls, muscle weakness/sarcopenia, pressure ulcer risk, and polypharmacy, and these risks are independent of other factors.
