Objective:To explore the predictive value of lipoproteins on the progression of critically ill patients to chronic critical illness (CCI).Methods:A retrospective cohort study was conducted to analyze clinical data of patients admitted to the intensive care unit (ICU) of Nanjing Drum Tower Hospital from January 1, 2020, to December 31, 2022. The levels of high-density lipoprotein (HDL), low-density lipoprotein (LDL) and apolipoproteins (ApoA-Ⅰ, ApoB) at 1, 3, 7, 14 and 21 days after admission to ICU were collected. The progression to CCI was recorded. CCI was defined as the length of ICU stay ≥14 days with sustained organ dysfunction [sequential organ failure assessment (SOFA) score ≥2]. Differences in lipoprotein levels between the patients with and without CCI were compared. Multivariate Logistic regression was used to analyze risk factors for critically ill patients progressing to CCI. Receiver operator characteristic curve (ROC curve) was drawn to evaluate the predictive value of lipoproteins on critically ill patients progressing to CCI.Results:A total of 200 patients were enrolled in the final analysis. 137 patients (68.5%) progressed to CCI, and 63 patients (31.5%) did not. The lipoprotein indicators in the CCI group showed a decrease after the acute phase, while the lipoprotein indicators in the non-CCI group showed an increase. The levels of HDL, LDL, ApoA-Ⅰ, and ApoB at various time points in the CCI group were significantly lower than those in the non-CCI group. HDL at 7 days in the CCI group was significantly lower than that in the non-CCI group [mmol/L: 0.44 (0.31, 0.61) vs. 0.67 (0.49, 0.75), P < 0.01]. Multivariate Logistic regression analysis showed that 7-day HDL was an independent risk factor for critically ill patients progressing to CCI [odds ratio ( OR) = 0.033, 95% confidence interval (95% CI) was 0.004-0.282, P = 0.002]. ROC curve analysis showed that the area under the ROC curve (AUC) of 7-day HDL for predicting critically ill patients progressing to CCI was 0.702, with a 95% CI of 0.625-0.779, P < 0.001. When the optimal cut-off value was 0.59 mmol/L, the sensitivity was 69.8%, and the specificity was 72.4%. Conclusions:The low level of lipoproteins is closely related to the progression of critically ill patients, and 7-day HDL has a certain predictive value for critically ill patients progressing to CCI. Continuously observation of the change trend of lipoprotein level is helpful to judge the progression of CCI in critically ill patients.

BACKGROUND:Stage Ⅲ Kümmell's disease is characterized by a high degree of vertebral compression and posterior wall defects.Most of the patients are elderly people with severe osteoporosis and various medical diseases.Clinically,some surgical methods are often at high risk and are controversial. OBJECTIVE:To investigate the clinical efficacy of screw placement combined with transpedicular impaction bone grafting in the treatment of stage Ⅲ Kümmell's disease. METHODS:The clinical data of injured vertebral screw placement combined with transpedicular impaction bone grafting in treatment of stage Ⅲ Kummell's disease from May 2016 to August 2021 were retrospectively analyzed.Visual analog scale score,Oswestry disability index,anterior vertebral heights,kyphotic Cobb angle and American Spinal Injury Association(ASIA)impairment scale were used to evaluate the effects of surgery.The operation time,intraoperative blood loss and complications were recorded.CT scans were used to evaluate the healing of injured vertebrae at the final follow-up visit. RESULTS AND CONCLUSION:(1)A total of 26 patients were included,with 7 males and 19 females,at the age range of 62-81 years[mean(69.7±4.8)years].The follow-up time was 18-60 months[mean(35.1±8.9)months].The average operative duration was 133.5 minutes(100-165 minutes),and the average intraoperative blood loss was 285.3 mL(210-350 mL).(2)Visual analog scale and Oswestry disability index scores 1 week after surgery were significantly lower than those before surgery.(3)At 1 week after surgery,the anterior vertebral height corrections and the Cobb angle were(9.0±0.7)mm and(16.2±1.0)°,respectively.During the follow-up period,the loss of vertebral height and kyphosis correction were(5.1±0.3)mm and(8.0±0.4)°,respectively.(4)14 patients(54%)had ASIA grade D before operation,which recovered to grade E at the last follow-up.CT scan showed that all patients achieved good osseous union.(5)Complications occurred in seven patients(27%),including hypostatic pneumonia in two cases,postoperative superficial wound tissue liquefaction in two cases,and adjacent vertebral compression fractures in three cases.(6)It is concluded that screw placement of the injured vertebra combined with transpedicular impaction bone grafting can rapidly rebuild spinal stability,effectively relieve pain and improve neurological function in the treatment of stage Ⅲ Kümmell's disease.This technique is an effective and relatively minimally invasive surgical option.

Since the first operational definition of cognitive frailty was proposed by the expert consensus group of the International Academy of Nutrition and Aging and the International Association of Gerontology and Geriatrics in 2013, frailty and neurocognitive assessment has become the standard diagnostic tool.Since then, the reported prevalence in the literature for cognitive frailty in community-dwelling elderly people vary by dozens of times, as a result of different scales and diagnostic cut-off points, seriously affecting health decision-making.This article reviewed the current literature with a focus on the re-recognition of the clinical significance of cognitive frailty, the limitations of existing assessment tools for diagnosis, and possible solutions in the future.

[Objective]To explore the clinical characteristics of neurobrucellosis in Kashi,Xinjiang Uygur Autono-mous Region,thus improve the diagnosis and treatment.[Methods]A retrospective analysis was conducted on the clinical data of 18 cases of neurobrucellosis who were admitted to the First People's Hospital of Kashi Prefecture between Decem-ber 2019 and January 2024.[Results]The study included 9 males and 9 females,with a median age of 36 years(range:17-54.5).A clear epidemiological history was found in all the 18 brucllosis patients,12 of whom presented with meningo-encephalitis,5 meningitis,and 1 encephalitis.Two comorbided with spinal meningitis,2 osteoarthritis and 1 epididymitis.Most frequently reported clinical symptoms were headache,fever and fatigue.The prevalence rates of brucellosis by rose bengal plate agglutination test(RBPT)and serum agglutination test(SAT)were 11/12 and 8/9,respectively.Two of 10 patients had positive blood cultures,four of 16 had positive cerebrospinal fluid(CSF)cultures and five of five were detect-ed to be positive by next-generation sequencing(NGS)for pathogens in CSF.CSF showed exudative changes and elevated number of leukocytes,with predominance of single nucleated cells.All patients were treated with the combined use of two to four from the drugs like doxycycline,rifampicin,ceftriaxone,cefixime,minocycline,levofloxacin and sulfanilamide.Most patients had a favorable prognosis.[Conclusions]Neurobrucellosis should be considered in all patients with central nervous system manifestations from endemic areas.If there are exudative changes in CSF,differential diagnoses can be made by serological testing,blood culture,CSF culture and NGS.NGS could significantly increase the accuracy for neuro-brucellosis diagnosis.

Objective To determine the neurotoxic effects of amyloid beta 42(Aβ42)oligomers and investigate the mechanism of their induction of Alzheimer's disease(AD)-like pathogenesis in neuronal cells.Methods Western blotting and transmission electron microscopy were used to identify the synthesized Aβ42 oligomers.In order to assess the impact of the oligomers,MTT assay was employed to measure cell viability in neuroblastoma cell line SH-SY5Y treated with 10μmol/L Aβ42 oligomers for 12 or 24 h,glutamatergic neurons derived from human embryonic stem cells(hESC)exposed to Aβ42 oligomers for 24,48,or 96 h,and corresponding control cells.TUNEL assay was utilized to assess the apoptosis of glutamatergic neurons.Additionally,immu-nofluorescence assay was applied to detect the changes in Aβ plaques and p-tau pathology.Results Western blotting displayed monomers and small-molecule aggregation(＜30 000)in our synthe-sized Aβ42 oligomers,and transmission electron microscopy showed that the synthesized oligomers were mainly in a shape of spherical particles.Treatment of 10 μmol/L Aβ42 oligomers for 12 and 24 h in SH-SY5Y cells significantly decreased cell viability when compared with the control cells[(70.89±2.54)％vs(100.00±2.02)％,(52.63±3.37)％vs(100.00±2.80)％,P＜0.05].The 10μmol/L oligomers treatment for 24,48 and 96 h also decreased cell viability in glutamatergic neu-rons(P＜0.05).The apoptotic rates was significantly higher in glutamatergic neurons after treat-ment for 48 and 96 h when compared to the control cells[(1.44±0.31)％vs(1.00±0.38)％,(1.75±0.64)％vs(1.00±0.31)％,P＜0.05].Furthermore,circular granular Aβ-positive plaque signals were observed in the glutamatergic neurons after treated with the oligomers for 24,48,and 96 h,but no such plaque signals were seen in the control cells.Additionally,glutamatergic neurons incu-bation with 10 μmol/L oligomers for 24 h resulted in tau hyperphosphorylation at the Thr231 site,with the average fluorescence intensity significantly higher than that in control cells(P＜0.05).Conclusion Aβ42 oligomers show toxic effects to both SH-SY5Y cells and glutamatergic neurons,and they can also induce glutamatergic neurons to produce AD pathology.

Objective:To compare the efficacies of posterior long segment instrumentation combined with transpedicular impaction bone grafting or with bone cement augmentation in treating stage III Kümmell disease.Methods:A retrospective cohort study was conducted to analyze the clinical data of 38 patients with stage III Kümmell disease who were admitted to Zhengzhou Orthopedic Hospital between January 2016 and December 2020. The study included 8 male and 30 female patients, with ages ranging from 59 to 81 years [(68.9±4.9)years]. The vertebral fractures occurred at T 8 in 1 patient, T 11 in 9 patients, T 12 in 10 patients, and L 2 in 10 patients. Seventeen patients underwent posterior long segment instrumentation combined with transpedicular impaction bone grafting (impaction bone grafting group), and 21 patients underwent posterior long segment instrumentation combined with bone cement augmentation (bone cement group). The surgical duration, intraoperative blood loss, and incidences of postoperative complications were compared between the two groups. Additionally, the visual analogue score (VAS), Japanese orthopedic association (JOA) score, and Cobb angle were compared before the operation, at 1 week and 3 months post-operation, and at the final follow-up for both groups. The study also compared bone healing at the last follow-up and postoperative complication rates between the two groups. Results:All the patients were followed up for 24-35 months [(28.7±2.9)months]. The impaction bone grafting group had a surgical duration of (150.7±25.4)minutes and intraoperative blood loss of (285.3±48.6)ml, significantly different from those in the bone cement group [(132.0±21.1)minutes, (251.4±44.8)ml] (all P<0.05). Before the operation, there were no significant differences in the VAS, JOA score, or Cobb angle between the two groups (all P>0.05).The VAS was (3.2±0.8)points, (2.7±0.5)points and (2.2±0.7)points in the impaction bone grafting group and was (2.7±0.6)points, (2.6±0.7)points and (2.4±0.8)points in the bone cement group at 1 week and 3 months post-operation and at the final follow-up, respectively. The VAS in the impaction bone grafting group was significantly higher than that in the bone cement group at 1 week post-operation ( P<0.05); however, no significant differences were found at 3 months post-operation or at the last follow-up (all P>0.05). There was no significant difference in the JOA score between the two groups at 1 week or 3 months post-operation, or at the final follow-up (all P>0.05). The Cobb angle in the impaction bone grafting group was (5.1±1.3)°, (5.9±1.8)° and (6.5±2.5)° at 1 week and 3 months post-operation, and at the final follow-up, significantly lower than that in the bone cement group [(8.4±1.6)°, (12.6±2.1)°, and (14.5±3.3)°] (all P<0.01). All the patients in the impaction bone grafting group achieved bone healing at the last follow-up. One patient in the impaction bone grafting group experienced delayed incision healing, whereas two patients in the bone cement group had poor bone healing. The complication rate was 5.9% (1/17) in the impaction bone grafting group and 9.5% (2/21) in the bone cement group ( P>0.05). Conclusions:Posterior long segment instrumentation combined with transpedicular impaction bone grafting or with bone cement augmentation are both effective in alleviating pain and improving the spinal function for stage III Kümmell disease. The former procedure is associated with longer surgical duration and increased intraoperative blood loss, but it can provide superior correction and maintenance of kyphosis deformity, promoting the healing of the injured vertebrae.

Objective:To compare the clinical effect of transpedicular impaction and grafting of allogeneic bone containing enriched bone marrow combined with posterior internal fixation and posterior subtotal vertebrectomy combined with posterior internal fixation in the treatment of stage III Kümmell′s disease.Methods:A retrospective cohort study was made on clinical data of 40 patients with stage III Kümmell′s disease admitted to Zhengzhou Orthopedic Hospital from June 2015 to December 2018. There were 10 males and 30 females, at age range of 57-79 years［(67.7±6.1)years］. A total of 19 patients were treated by transpedicular impaction and grafting of allogeneic bone containing enriched bone marrow combined with posterior internal fixation (impaction bone graft group), and 21 patients by posterior subtotal vertebrectomy combined with posterior internal fixation (subtotal vertebrectomy group). Operation time and intraoperative blood loss were compared between the two groups. Degree of pain, lumbar dysfunction and degree of kyphosis were evaluated by visual analogue scale (VAS), Japanese Orthopedic Association (JOA) score and kyphotic Cobb angle before operation, at 1 week after operation and at the last follow-up. Bone healing time was compared between the two groups. The complications of the two groups were observed.Results:All patients were followed up for 25-64 months［(40.6±10.4)months］. Operation time and intraoperative blood loss were (130.0±10.1)minutes and (284.5±43.5)ml in impaction bone graft group, lower than those in subtotal vertebrectomy group［(253.8±33.2)minutes, (889.1±95.7)ml］(both P<0.01). There were no significant differences in VAS, JOA score or kyphotic Cobb angle between the two groups before operation, at 1 week after operation and at the last follow-up (all P>0.05). Both VAS and JOA score showed significant differences within each group at any time point (all P<0.01). In both groups, the kyphotic Cobb angle reduced significantly at 1 week after operation when compared with that before operation (all P<0.01), and the angle showed a slight increase at the last follow-up, but remained significantly lower than that before operation (all P<0.01). There were no relapse of pain or aggravation of kyphosis. Bone healing time in impaction bone graft group［4.4(4.0, 5.0)months］was significantly shorter than that in subtotal vertebrectomy group［6.4(5.2, 8.1)months］( P<0.01). There were 2 patients with delayed healing of surgical incision in impaction bone graft group, with the complication rate of 11%. There were 2 patients with dural tear and 3 patients with delayed healing of surgical incision in subtotal vertebrectomy group, with the complication rate of 24%. The complication rate was not statistically significant between the two groups ( P>0.05). No loosening or breakage of internal fixation was observed during the follow-up. Conclusions:Transpedicular impaction and grafting of allogeneic bone containing enriched bone marrow combined with posterior internal fixation and posterior subtotal vertebrectomy combined with posterior internal fixation are effective in the treatment of stage III Kümmell disease. However, the former can shorten the operation time, reduce the intraoperative blood loss and accelerate the healing of injured vertebral bone, suggesting a relatively minimally invasive surgical method for reconstruction and maintenance of spinal biomechanical stability.

Objective:To evaluate whether pelvic fixation is needed in patients undergoing posterior lumbosacral hemivertebra (LSHV) resection and long fusion.Methods:All 32 adult spinal deformity patients with posterior hemivertebra (HV) resection and long segment fixation treated from April 2005 to August 2019 were analyzed retrospectively, including 12 males and 20 females with a mean age of 32.9±8.8 years. According to the state of coronal balance distance (CBD), there were 15 cases of type A (preoperative CBD≤ 30 mm), 1 case of type B (preoperative CBD>30 mm and C 7 plumb line offset to the concave side), and 16 cases of type C (preoperative CBD>30 mm and C 7 plumb line offset to the convex side). The clinical and imaging data before operation, immediately after operation and at the last follow-up were collected, and the short-term and long-term complications related to operation were recorded. The improvement of Cobb angle and coronal balance of primary curve and compensatory curve were evaluated on the whole spine frontal and lateral X-ray films, and the change of coronal balance type after operation was evaluated. According to the mode of distal internal fixation, the patients were divided into two groups: PF group (pelvic fixation): distal fixation to iliac or sacroiliac; NPF group (non-pelvic fixation): distal fixation to L 5 or S 1. Results:All 32 patients were followed up with an average time of 3.9±2.6 years (range 2-11 years). The Cobb angle of primary curve in PF and NPF groups were 42.6°±13.5° and 41.3°±10.9° respectively before operation, and corrected to 13.1°±5.4° and 17.7°±5.8° respectively after operation. It maintained at 13.4°±5.1°and 18.5°±6.7° in the two groups at the last follow-up, respectively ( FPF=32.58, FNPF=28.64, P<0.001). The correction rates were 69.3%±11.8% and 57.6%±10.3%, respectively ( t=2.14, P=0.012). The compensatory curves of in the two groups were corrected from 54.9°±14.8° and 46.8°±13.6° before operation to 17.3°±9.6° and 15.4°±8.4° after operation. It also maintained at 18.5°±8.8°and 17.6°±9.5° in the two groups at the last follow-up, respectively ( FPF=42.97, FNPF=38.56, P<0.001). The correction rates were 68.4%±16.7% and 67.2%±14.9%, respectively ( t=0.17, P=0.849) in the two groups. In PF group, the primary and compensatory curve were similar (69.3%±11.8% vs. 68.4%±16.7%, t=0.15, P=0.837), while the correction rate of compensatory curve in NPF group was significantly higher than that of the primary curve (67.2%±14.9% vs. 57.6%±10.3%, t=2.13, P=0.013). Coronal decompensation occurred in 12 patients (12/32, 37.5%). The CBD in PF and NPF groups was corrected from 33.3±11.2 mm and 28.8±8.1 mm preoperatively to 18.5±3.5 mm and 27.1±6.8 mm postoperatively, respectively, and it showed no significant change at the last follow-up ( FPF=41.61, P<0.001; FNPF=0.38, P=0.896). While the CBD in PF group was significantly better than that in NPF group ( t=3.23, P=0.002; t=2.94, P=0.008). The incidence of coronal decompensation in PF group was 0%, which was significantly lower than 50% (12/24) in NPF group (χ 2=6.40, P=0.014). In addition, 6 cases in PF group were type C coronal decompensation before operation, and the coronal balance was corrected to type A after surgery (100%). Among 10 patients with type C coronal decompensation in NFP, 4 (40%) patients returned to type A after operation, and the difference was statistically significant (6/6 vs. 4/10, χ 2=5.76, P=0.034). Conclusion:Coronal decompensation (12/32, 37.5%) is not rare in patients after posterior LSHV resection and long fusion. Attention should be paid to the match of the corrections between lumbosacral deformity and compensatory curve, which is of great significance in coronal balance reconstruction. Pelvic fixation is helpful to reduce the incidence of postoperative coronal decompensation, especially for the type C patients.

Objective:To evaluate the safety and efficacy of one-stage posterior-only jumping hemivertebra (HV) resection combined with respective short fusions in the treatment of congenital scoliosis (CS) caused by multiple HVs.Methods:All of 13 consecutive patients with multiple HVs treated surgically from January 2010 to December 2017 were retrospectively reviewed, including 4 males and 9 females with a mean age of 3.7±1.2 years. One child had 4 HVs, and the rest had 2 HVs. The responsible HVs causing local scoliosis/kyphosis deformity or coronal plane deviation were selected as the target of resection. The distal HV was removed firstly and then the proximal one was resected; both of the fixation vertebraes were horizontalized during surgery. The clinical and imaging data of the children before the initial operation, immediately after the operation and at the latest follow-up were collected, and the short-term and long-term complications related to surgery were recorded. The data were evaluated on the whole-standing spine anteroposterior and lateral films, including the corrections of proximal and distal main curves, coronal balance, local kyphosis, and the improvement of spinal growth height (upper and lower internal fixation length, T 1-S 1 length). At the same time, the re-progression of coronal and sagittal deformities of the spine during growth was recorded (coronal decompensation: emerging postoperative curve progression more than 20°; kyphosis progression: kyphosis aggravation between upper and lower internal fixation more than 40°) and internal-fixation-related complications (screw cutting, screw malposition) were recorded. Results:Dual HVs were resected in each child, of which 8 (61.5%) were located on contralateral side of the spine, and 5 (38.5%) were located on ipsilateral side of the spine. The follow-up time was 6.2±3.3 years (range 2.0-10.5 years) after surgery. The Cobb angles of proximal and distal main curves were 36.7°±11.8° and 35.2°±7.8° respectively before surgery and were corrected to 9.7°±6.6° and 6.1°±4.1° respectively after surgery ( F=31.249, F=93.83, P< 0.001) ( t=6.888, t=10.954, P<0.001), and the correction rates was 73.6%±19.6% and 82.7%±11.7%, respectively. They were maintained at 14.3°±5.4° and 8.0°±4.6° at the latest follow-up, showing the correction rates loss of 15.8%±26.9% and 6.9%±7%, respectively. The coronal balance improved from 17.2±14.8 mm pre-operatively to -0.2±15.7 mm postoperatively ( t=2.703, P=0.008), and it remained at 0±18.4 mm at the final follow-up ( F=4.137, P=0.024). The T 1-S 1 length was corrected to 273.8±27.3 mm postoperatively, slightly increased compared with pre-operation 256.3±24.0 mm, ( t=0.680, P=0.527), and significantly increased to 333.2±33.4 mm at the latest follow-up ( t=2.986, P<0.001; F=6.704, P=0.003). Seven patients had local kyphosis before operation, which was significantly improved from 32.2°±13.6° to 6.1°±9.8° with a correction rate of 93.4%±27.0% after surgery ( t=3.355, P=0.004), which showed no significant loss of correction at the latest follow-up (5.4°±10.4°) ( F=11.187, P=0.002). Six patients (46.2%) developed coronal decompensation (Curve magnitude >20 °), with an average of 21.7°±1.9°. Two cases (15.4%) had progressive kyphosis between the thoracic regional internal fixations at 3 months after surgery, which were 68° and 58° respectively. After bracing, both coronal decompensation and sagittal kyphosis were improved. At the last follow-up, the coronal decompensation was improved to 14.7±8.9° and the kyphosis was alleviated to 55° and 46°, respectively. Conclusion:Posterior-only skipping hemivertebra resection and short fusion is a safe, effective procedure yielding significantly improvement of the growth imbalance and reginal spinal deformities of CS with multiple HVs. The mid-term follow-up results showed that the progress of the scoliosis was common during the growth period, which could be further controlled by supplementary brace treatment.
