New treatment options of acute myeloid leukemia (AML) are rapidly emerging. Pre-clinical models such as ex vivo cultures are extensively used towards the development of novel drugs and to study synergistic drug combinations, as well as to discover biomarkers for both drug response and anti-cancer drug resistance. Although these approaches empower efficient investigation of multiple drugs in a multitude of primary AML samples, their translational value and reproducibility are hampered by the lack of standardized methodologies and by culture system-specific behavior of AML cells and chemotherapeutic drugs. Moreover, distinct research questions require specific methods which rely on specific technical knowledge and skills. To address these aspects, we herein review commonly used culture techniques in light of diverse research questions. In addition, culture-dependent effects on drug resistance towards commonly used drugs in the treatment of AML are summarized including several pitfalls that may arise because of culture technique artifacts. The primary aim of the current review is to provide practical guidelines for ex vivo primary AML culture experimental design.

To evaluate the results of surgery for congenital craniovertebral junction (CVJ) anomalies with atlantoaxial dislocation (AAD)/basilar invagination (BI) and compare the results of transoral odontoidectomy and posterior fusion (TOO+PF) with only posterior fusion (PF) in patients with irreducible AAD/BI.

All 94 patients with congenital CVJ anomalies with AAD/BI operated on during the 3-year study period (June 2013-May 2016) were included. Of these patients, 55 had irreducible AAD/BI and the remaining 39 had reducible AAD/BI. TOO+PF was restricted to patients (34/94; 36.2%) with irreducible AAD/BI when reduction and realignment by intraoperative C1-C2 facet joint manipulation were considered technically difficult and risky. The remaining patients with irreducible AAD/BI and all the patients with reducible AAD/BI (60/94; 63.8%) were managed with only posterior fusion. Poor preoperative Nurick grade, preoperative dyspnea/lower cranial nerve deficits, and syringomyelia were associated with significantly higher ion for irreducible AAD/BI when only PF techniques are technically difficult/risky.

The treatment of unilateral CFD in patients without neurologic deficits remains controversial, especially in the choice of the best surgical approach. Our objective is to determine the way spine surgeons from Latin America manage this condition.

Luminespib order regarding management and surgical strategies was conducted by the AO Spine Latin American Trauma Study Group considering the treatment of unilateral CFD.

All AO Spine Latin American Trauma Study Group members were sent a link to the survey, among whom 285 replied, with 197 respondents answering all the questions. Nonsurgical management was considered by 25% of the surgeons. The majority stated that magnetic resonance imaging is necessary (65%) to treat this type of patient. A posterior approach was preferred by 44%, an anterior approach by 29%, and a combined approach by 25%, while 2.2% did not answer. Traction was not used by the majority of respondents (62%). In the setting of an anterior disk herniation, the majority of surgeons preferred to employ an anterior (45%) or combined (44%) approach versus an isolated posterior approach (only 0.5%). Comparing early versus late cervical trauma, fewer surgeons adopted an isolated anterior approach with the latter (29% vs. 15%).

Wide variations exist in the management of unilateral CFD by Latin American surgeons, with early injuries generally treated using either an anterior or posterior approach and treated early but after an MRI, while a combined approach is used more commonly with late injuries. Either an anterior or combined approach is used when disk herniation is present.

Previous studies have shown decreased pain scores with ziconotide as a first-line agent for intrathecal drug therapy (IDT). Subset analysis suggests that patients with neuropathic pain have greater improvement. We prospectively examine the role of first-line ziconotide IDT on the tridimensional pain experience in ziconotide IDT-naive patients with neuropathic pain.

We included patients who underwent a successful ziconotide trial and were scheduled for standard-of-care IDT pump placement. Scores were collected at baseline and latest follow-up for the following measures Short-Form 36 (SF-36), Oswestry Disability Index (ODI), Beck Depression Inventory, and Pain Catastrophizing Scale (PCS). #link# Numeric rating scale (NRS) scores were also collected at each follow-up visit to monitor patients' pain levels and to guide ziconotide dose titration. Responders were identified as patients who had a previously established minimum clinically important difference of a ≥1.2-point reduction in NRS current scores.

Proximal junctional kyphosis (PJK) is a well-recognized complication following surgery for adult spinal deformity (ASD); however, definitions for PJK and its clinical implications can significantly vary by study. This study compares multiple definitions of PJK and describes incidence and clinical significance by definition.

From 2014 to 2019, patients with ASD who underwent spinal fusion were identified. Nine definitions of PJK were created based on previously established definitions using the following upper instrumented vertebra+2 (UIV+2) sagittal Cobb measurements A= ≥10 postoperative AND preoperative, B= ≥10 postoperative, C=≥10 preoperative, D= ≥15 postoperative AND preoperative, E= ≥15 postoperative, F= ≥15 preoperative, G= ≥20 postoperative AND preoperative, H= ≥20 postoperative, I= >20 preoperative. Incidence of PJK was calculated by definition. Area under the curve (AUC) was calculated based on a receiver operating characteristic to assess ability to predict proximal junctional failure (PJF). nguishing patients who developed PJF.

Survival after meningioma surgery often is reported with inadequate allowance for competing causes of death.

We processed the French Système National des Données de Santé database using an algorithm combining the type of surgical procedure and the International Classification of Diseases to retrieve appropriate cases of meningiomas. The cumulative incidence of meningioma-related death was the primary end point. A competing risk analysis was performed to identify factors associated with meningioma-specific death of patients who underwent meningioma surgery.

The risk of meningioma-related death at 1, 2, and 3 years respectively was 2.4%, 95% confidence interval [CI] 2-2.7; 3%, 95% CI 2.6-3.4; and 3.1%, 95% CI 2.7-3.6. In the adjusted Fine-Gray competing risk regression for meningioma cause-specific survival, age at surgery (subdistribution hazard ratio [SHR] 1.07, 95% CI 1.05-1.09, P < 0.001), mortality-related morbidity index (SHR 1.68, 95% CI 1.07-2.63, P= 0.025), expenditure-related morbidity index cific survival after meningioma surgery is greater in younger, low-comorbidity adults with spinal and benign meningioma. Those with an intracranial, progressing malignant tumor requiring cerebrospinal fluid shunting and having a severe global health-state have a significant increased risk of meningioma-related death. link2 Redo surgery failed to improve the outcome. We recommend the use of competing risk model in meningioma studies in which unrelated mortality may be substantial, as this approach results in more accurate estimates of disease risk and associated predictors.Thesis studied chemotherapy-related cognitive impairment via RS-fMRI and DTI. Chemotherapy were included 19 cases of patients with early breast cancer, neuropsychological tests were carried out before and after chemotherapy, RS-fMRI and DTI evaluation. In RS-fMRI with ReHo reflects brain activity. In the DTI with FA reflect the integrity of the white matter. Determining the region of interest by image analysis, neuropsychological test score is calculated by paired t-test, and FA change ReHo values of ROIs. Finally, in the chemotherapy group for pairing correlation analysis t test scores change in meaningful inspection and change ReHo and FA. Chemotherapy after chemotherapy than before chemotherapy difference memory test and self-evaluation of cognitive (P less then 0.05). ReHo value increased brain regions are the right orbitofrontal region and the left dorsolateral prefrontal cortex; decline in brain regions are the anterior inferior cerebellar lobe, cerebellar lobe, right middle temporal gyrus and the superior temporal gyrus, the lower right of the centre area, as well as central gyrus. This prospective study resting state and RS-fMRI functional magnetic resonance diffusion tensor imaging study DTI sequence combination chemotherapy for breast cancer-related cognitive disorders, supporting "chemo brain" point of view exists. Chemotherapy can cause memory decline, accompanied by a partial area of the brain and white matter integrity in brain activity changes. Tips RS-fMRI and DTI have potential applications in assessing chemotherapy-related cognitive impairment.

To evaluate the safety and accuracy of S2 alar-iliac (S2AI) screw placement guided by a 3-dimensional (3D)-printed surgical guide template.

The data of 27 patients treated with S2AI screws were analyzed. S2AI surgical guide templates were designed and printed, and S2AI screw placement was completed intraoperatively with the guide templates. Postoperative computed tomography was performed to measure screw path parameters, namely the sagittal angle (SA), the transverse angle (TA), the horizontal distance (HD) between the entry point of the screw and the median sacral crest, and the vertical distance (VD) between the entry point of the screw and the lower edge of the first posterior sacral foramen. Screw placement was graded according to the Oh grading criteria.

A total of 54 S2AI screws were placed. The screw grades were as follows 52 screws were considered grade 0, 2 were grade 1, none were grade 2, and none were grade 3. Thus grade 0 accounted for 96.3% of the screws. When the preoperatively planned SA (32.3° ± 2.0°), TA (42.1° ± 3.9°), HD (5.1 ± 1.1) mm, and VD (19.0 ± 2.4) mm were compared with the corresponding postoperative SA (31.9° ± 3.8°), TA (42.5° ± 4.0°), HD (4.9 ± 1.1) mm, and VD (19.1 ± 2.3) mm, no significant differences were identified (P > 0.05).

In this study, we used a novel approach to investigate the proportion of soil organic carbon (SOC) in invertebrates and microbial biomass. The study was conducted on a peatland site after the end of peat extraction. There was a large difference in the isotopic abundance of 14C between the 8000-year-old peat and air. We used a two-pool isotope mixing model to reveal the fraction of soil-derived C in the organisms and in dissolved organic carbon in soil water. link3 The contribution of soil-derived C was found to be highest in microbial biomass (61%) and earthworms (22%). Some contribution of soil-derived C was detected in fungus gnats (2%), but not in other insects or in spiders. These findings are important for developing evidence-based radioecological models based on correct understanding of the relative contributions of atmospheric C vs. SOC in organisms.
