In MC 1, BMF was lower than endplates without MC (absolute difference -22.3%; p < 0.001); in MC 2, BMF was higher (absolute difference 21.0%; p < 0.001). Absolute BMF differences between affected and unaffected marrow were larger in patients with greater disability (p = 0.029-0.032) and were not associated with pain (p = 0.49-0.83).
 
  BMF is significantly altered in MC. Water-fat MRI enables BMF measurements that may eventually form the basis for quantitative assessments of MC severity and progression.

  To develop and assess the reliability of new nomenclature system that systematically organizes osteotomy techniques and briefly describes the surgical approach, the surgical sequence, and the fixation technique for cervical spine deformity (CSD).
 
  We developed a new classification system (SOF system) for CSD surgery that describes the sequence of surgical approach (S), the grade of osteotomy (O), and the information of fixation (F) using alphanumeric codes. Twenty CSD osteotomies (8 anterior osteotomies, 12 posterior osteotomies) were included in this study to evaluate the inter- and intra-observer agreement based on operation records. Six observers performed independent evaluations of the operation records in random order.  https://www.selleckchem.com/products/bpv-hopic.html  Each observer described 20 CSD surgeries using the SOF system twice (> 30days between assessments) based on operation records to validate SOF system.
 
  Overall agreement (among all six observers at the initial assessment) on the anterior and posterior osteotomy was ICC = 0.96 and ICCe a consistent description of the various CSD surgeries and its use will provide a common frame for CSD surgery and help communicate between surgeons.
  In Asian countries, proximal gastrectomy is a standard treatment option for early primary gastric cancer located in the upper third of the stomach. However, laparoscopic proximal gastrectomy (LPG) is not widely employed due to the technical difficulty of laparoscopic esophagojejunal anastomosis. Therefore, we began performing laparoscopic hand-sewn esophagojejunal anastomosis. In this report, we describe the technique of this method and the short-term surgical outcomes.
 
  Between February 2016 and June 2020, 18 patients underwent LPG with double-tract reconstruction at our institution. Laparoscopic hand-sewn esophagojejunal anastomosis was attempted for all patients.
 
  The median operative time for the 18 patients was 431 min (range 301-549 min), and the estimated blood loss was 100 mL (range 0-1524 mL). The median time for the hand-sewn esophagojejunostomy was 42 min (range 26-81 min). Only one case was converted to open surgery after the reconstruction due to bleeding from an artery of the lesser curvature. No anastomotic leakage was observed in any patients (0/18, 0 %); however, two patients developed anastomotic stenosis (2/18, 11%). The mean length of postoperative hospital stay was 10 days (range 8-28 days).
 
  The laparoscopic hand-sewn esophagojejunal anastomosis in LPG is a simple, cost-effective, and safe procedure. We believe that our method is a feasible choice. However, careful and longer follow-up of more patients is necessary to determine the advantages of our method.

We find that the thermodynamic stability of this hourglass-shaped, hydrophobic connection between two vesicles is largely increased by the strong curvature of small vesicles, whereas the intrinsic barrier to form a stalk, i.e., associated with dimple formation and lipid tails protrusions, is similar to the case of two, apposing, planar membranes. A significant reduction of the barrier of stalk formation, however, stems from the lower dehydration free energy that is required to bring highly curved vesicle into a distance, at which stalk formation may occur, compared to the case of apposing, planar membranes.Little is known about the measurement properties of numeric rating scales (NRS) for pain in AD. We evaluated a novel NRS for skin-pain and existing NRS for average overall-pain in adults with AD. Self-administered questionnaires and skin-examination were performed in 463 AD patients (age 18-97 years) in a dermatology practice setting. Numeric rating scales skin-pain and average overall-pain had moderate correlations with each other, and multiple clinician-reported and patient-reported AD severity outcomes (Spearman correlations, P  less then  0.0001). There were significant and stepwise increases of NRS skin-pain and average overall-pain scores with patient-reported global severity (Wilcoxon rank-sum test, P  less then  0.0001). Floor-effects were observed for NRS skin-pain and average overall-pain. Changes from baseline in NRS skin-pain and average overall-pain showed weak-moderate correlations with changes of POEM, vIGA-AD*BSA, SCORAD, and DLQI. Using an anchoring approach, the optimal interpretability band for NRS skin-pain was clear = 0, mild = 1-3, moderate = 5-6, severe = 7-9, and very severe = 10 (weighted kappa = 0.4923). The thresholds for minimally clinically important difference for NRS skin-pain ranged from 2.2 to 2.9. NRS skin-pain and average overall-pain showed moderate-good reliability. Numeric rating scales skin-pain and average overall-pain had sufficient validity, reliability, responsiveness, and interpretability in adults with AD, and were inherently feasible as single-items for use in clinical trials and practice.
  The sensitivity of suspicious lung nodules biopsied by currently available techniques is suboptimal. Robotic-assisted navigation bronchoscopy (RANB) is a novel method for biopsying lung nodules. Our study objective was to determine the sensitivity for malignancy and overall diagnostic accuracy for RANB when combined with cone beam CT (CBCT) for secondary confirmation.
 
  52 consecutive patients were prospectively enrolled. Demographic data, nodule characteristics, procedural information, and follow-up results were obtained.
 
  Mean patient age was 66, with the majority Caucasian (73%) females (65%) with a similar number of never (46%) and former (46%) smokers. 15 patients had a history of cancer and 3 had a prior thoracic surgery. 59 total nodules were included as 7 patients had two nodules biopsied. Mean nodule diameter was < 2cm in all dimension with the majority solid (41, 70%) and located in the upper lobes (left 22, 37%; right 17, 29%). Bronchus sign was absent (32, 54%) or present (27, 46%) in a similar number.
