Obesity is a well-established risk factor for poor neurological outcomes, and bariatric surgery has been shown to improve many aspects of cognitive function. Factors underlying improved cognition following surgery are not yet fully established. A recent study of bariatric surgery patients demonstrated lower preoperative alkaline phosphatase concentrations were linked to greater postoperative cognitive improvement, but this link has not been examined via liver biopsy. The current study examined postoperative cognitive function in individuals with and without fibrosis at the time of bariatric surgery. It expected that those with fibrosis would demonstrate poorer postoperative cognition.
Thirty-six bariatric surgery patients underwent routine liver biopsy at the time of surgery and completed cognitive testing 1 month postoperatively.
Bariatric surgery patients with fibrosis demonstrated poorer performance on a task of executive function (maze errors, P = 0.01) and verbal memory (recognition memory, P = 0.01).
Bariatric surgery patients with fibrosis demonstrated poorer cognition following surgery, providing further evidence for the connection between liver disease and cognitive function. Future work examining mechanisms underlying bariatric postoperative cognitive changes should include examination of broader metabolic functions, particularly liver function.

In undertaking international neurosurgical trials it is useful to understand international patient demographics and potential patient populations that study results will apply to. The STITCH(Trauma) trial included 59 centres from 20 countries, which were requested to screen all patients with traumatic intracerebral haemorrhage. This paper reviews these data.
Demographic, clinical and exclusion reason data were analysed. Comparisons were made between patients who were included in the trial and patients who were potentially eligible (but not included in the trial) and patients who were not potentially eligible.
Screening evidence was returned for 1735 patients, 11% of these may potentially have been eligible, of whom 52% were not included because consent could not be gained. By country, median age per centre ranged from 26 years (Egypt) to 67 years (Germany), median time from injury to screening ranged from 5 h (Germany and Nepal) to 16 h (India), median intracerebral haemorrhage (ICH) volume ranged from 5 ml (Germany) to 30 ml (China), the proportion of male patients ranged from 56% (Egypt) to 91% (Canada) and the proportion of patients with both pupils reactive ranged from 68% (China) to 98% (Nepal). The most common exclusion reasons were ICH volume < 10 ml (49%) and presence of subdural haemorrhage/extradural haemorrhage or SDH/EDH requiring surgery (20%).
Data presented here including international patient demographics and reasons for patient ineligibility will be useful for future traumatic ICH studies.

One third of men undergoing radical prostatectomy have a comorbid inguinal hernia (IH). Previous studies have shown that adding total extraperitoneal (TEP) IH repair to extraperitoneal laparoscopic radical prostatectomy (LRP) lacks adverse effects. However, outcomes of extraperitoneal robot-assisted laparoscopic radical prostatectomy (RALP) and TEP are unknown. We compared RALP+TEP with LRP+TEP and also with RALP alone.
Eleven RALP+TEP cases were retrospectively compared with 26 LRP+TEP cases and 22 control RALP without TEP. Outcomes compared between groups included operative time, estimated blood loss (EBL), discharge hematocrit (hct), time to diet advancement, length of hospital stay (LOS), postoperative complications, and hernia recurrence.
Unilateral TEP added 32 minutes to RALP and 31 minutes to LRP, whereas bilateral TEP added 80 minutes to RALP and 36 minutes to LRP. Adenosine Cyclophosphate There were no differences between RALP+TEP and LRP+TEP or RALP without TEP controls in regard to EBL, discharge hct, time to diet advancement, LOS, or postoperative complications. One patient developed an anterior mesh seroma, which resolved without intervention. No IH recurrences were noted on the mean follow-up of 33 months in the RALP group and 50 months in the LRP cohort.
Unilateral and bilateral TEP added operative time to RALP but had equivalent outcomes to both LRP+TEP and RALP alone. This is likely due to the similar surgical space used for RALP and TEP, which obviates the need for substantial further dissection. For men with prostate cancer and comorbid IH, combined RALP+TEP appears to be an appropriate surgical combination.

To examine ocular lens parameters and structural changes to elucidate mechanisms underlying the myopic shift and cataract-related changes that occur in some patients during hyperbaric oxygen (HBO) therapy.
Scheimpflug images (Nidek EAS-1000) of the crystalline lens, measurements of scattered light, objective refraction, keratometry, tonometry, and axial length of the eye were obtained after the first day of HBO therapy and repeated when patients had completed 19 days of the treatment.
Significant reduction in mean (± SD) optical density was found in the lens nucleus, -2.8 (± 4.3) units (p = 0.009) and -2.2 (± 4.1) units (p = 0.027) within circular and oval areas, respectively. Significant decrease in mean (± SD) backward scattered light was measured, -0.4 (± 0.8) units (p = 0.022). Mean (± SD) myopic shift was -0.58 (± 0.39) diopters (p < 0.001), whereas cortical optical density, forward scattered light, lenticular parameters, keratometry, tonometry, anterior chamber depth, and axial length of the eye appeared unchanged.
Transient myopic shift reported in patients during HBO therapy is attributed to changes in the refractive index of the lens. No changes in lens curvatures or thickness were found after treatment.

Rodent studies of SWD after TBI are scarce, however, because of lack of appropriate TBI models reproducing acceleration-deceleration forces and compatible with electroencephalography/myography (EEG/EMG)-based recordings of vigilance states. We therefore adapted the Marmarou impact acceleration model to allow for compatibility with EEG-headset implantation. After implantation of EEG/EMG electrodes, we induced closed TBI by a frontal, angular hit with a weight-drop device (56 rats, weight 2500 g, fall height 25 cm). Subsequently, we tested our model's usefulness for long-term studies on a behavioral, electrophysiological, and histological level. Neurological, motor, and memory deficits were assessed with the neurological severity score, open field, and novel object recognition tests, respectively. EEG/EMG recordings were performed in both Sham (n = 7) and TBI (n = 7) rats before and 1, 7, and 28 days after trauma to evaluate sleep-wake proportions and post-traumatic implant stability. Histological assessments included hematoxylin and eosin staining for parenchymal damage and hemorrhage and amyloid precursor protein staining for diffuse axonal damage. All rats survived TBI without major neurological or motor deficits. Memory function was impaired after TBI at weeks 1, 2, and 3 and recovered at week 4. EEG implants were stable for at least 1 month and enabled qualitative and quantitative sleep analyses. Histological assessments revealed no major bleedings or necrosis but intense diffuse axonal damage after TBI. This approach fulfills major pre-conditions for experimental TBI models and offers a possibility to electrophysiologically study behavioral states before and after trauma.Fe- and Fe/Cu-based logwood inks were synthesized following recipes in nineteenth and early twentieth century manuals and were characterized by EPR, ESI-MS, FTIR, and Raman spectroscopies. This multi-technique approach allowed us to shed light on the structures of the complexes responsible for the inks' colors and to obtain vibrational signatures that can be used to identify the different inks in works of art and in historic documents. Information on the nature and chemical properties of the complexes formed between a dye and a mordant is important as these determine, at least in part, their lightfastness. EPR permitted to determine the coordination environment of the metallic ions. The results of the ESI-MS analysis demonstrated, for the first time, the breakdown of the hematein molecule during the ink preparation, and that the colorants are formed by the complexation of the metallic ions by hematein breakdown products, mainly catechol and/or bicyclic compounds. The FTIR spectra obtained were found to be dominated by bands due to the binding medium and sulfates used as reagents. The Raman analysis showed that the characteristic features for the different inks studied depend on the historic recipe used, attesting to the challenges that their identification and characterization in works of art present. In the Raman spectra of the inks applied on paper, broadening of bands in the 750-400 cm(-1) range are observed when compared to the spectra of the inks' powders, possibly due to the interaction of the compounds with the cellulose in the substrate.Fluorescent and colorimetric pH probe possess many advantages including rapid response time, nondestructive testing, and excellent pH sensitivity. However, they usually cannot be utilized simultaneously in both acidic and basic pH ranges. In this study, a new selective and sensitive fluorescent and colorimetric pH probe, 4-(8-quinolyl)amino-7-nitro-2,1,3-benzoxadiazole (1), was designated and synthesized. The optical probe exhibited dual-responsive pH ranges to both acidic and basic aqueous solutions. When the solution pH was gradually increased from 8.5 to 13.3, the absorption spectra of 1 showed an obvious hyperchromicity, accompanied with a red shift of the absorption band at 340 nm, a blue shift of the absorption band at 482 nm, and a distinct color change from orange to violet pink to yellow. Within the pH range from 2.2 to 0.2, the fluorescent spectra of 1 showed a "turn-on" response signal to solution pH. In order to understand the response mechanism of the probe to solution pH, the probe molecule was split into two parts, 8-aminoquinoline (2) and 4-amino-7- nitro-benzofurazan (3).
