Visual impairment (VI) may lead to worsening functional status and disability. Although disability is very difficult to reverse, it is usually preceded by frailty that may be reverted more easily. It is possible that VI is also related to frailty.
 
  To assess the relationship between VI and worsening of the frailty status.
 
  Data were taken from the Toledo Study for Healthy Aging (TSHA), a cohort study of community-dwelling people older than 65years living in one Spanish province who were followed for 5years. 1181 participants were included. VI was self-reported and frailty was operationalized using the Fried's phenotype adapted to a Spanish population. Models of multivariate logistic regression were built to assess the associations.
 
  The mean age was 73.9 (Standard Deviation (SD) = 5years) and 58.5% were females. Pre-frailty/frailty prevalence at baseline and follow-up were 41.2/5% and 36.2/12.5%, respectively, and VI was reported by 14.1%. After adjusting for age, gender, education level, tobacco consumption, type 2 diabetes mellitus, high blood pressure, cardiovascular disease, depressive symptoms and cognitive status, odds ratios for the development of frailty by VI were 2.5 (95% Confidence Interval (CI) 1.5-4.4) for non-frail, 2.7 (95% CI 1.3-5.7) for pre-frail and 1.9 (CI 0.6-6.00) for robust participants. The frailty domains whose appearance was most increased by VI were slowness, low energy, low physical activity and weakness.
 
  Our findings support that VI worsens frailty in the early stages of its development (pre-frailty). VI impairs several frailty items at the same time.
 
  Our study highlights the need to assess both VI and frailty for the prevention of frailty and disability in older people.

Natural phytocompounds such as curcumin shown promising anti-amyloidogenic activity. In the present study, selective phytocompounds such as piperine, cinnamaldehyde, eugenol, and cuminaldehyde present in Piper nigrum L, Cinnamomum zeylanicum Blume, Eugenia caryophyllus Thumb, and Cuminum cyminum L, respectively were analyzed for anti-amyloidogenic activity using hen egg white-lysozyme (HEWL) as a model system. Out of the selected phytocompounds, piperine showed the most significant anti-amyloidogenic activity, as evident from in vitro assays that were validated by in silico molecular docking study. Piperine showed 64.7 ± 3.74% inhibition of amyloid formation at 50 μM concentration, as observed by Thioflavin T assay. Subsequently, the anti-amyloidogenic activity of piperine was further validated by congo red, intrinsic fluorescence assay, and transmission electron microscopy analysis. The in silico molecular binding interaction showed piperine with the highest docking score and glide energy. Piperine was found to be interacting with amyloidogenic region residues and Trp62, the most important residue involved in the amyloidogenesis process. In conclusion, piperine can be used as a positive lead for a potential therapeutic role in targeting diseases involved amyloidogenesis.
  Retinal nerve fiber layer thickness (RNFL) is a biomarker of neuroaxonal loss and index of visual function in multiple sclerosis (MS). We aimed to assess the correlation between radiomic features and RNFL, visual acuity (VA) at patients' presentation, visual outcome (VO), and clinical diagnosis.
 
  We reviewed imaging and clinical data of 25 patients with a first episode of optic neuritis (ON) (14 females, 11 males; 5 bilateral ON; 7 left ON; 13 right ON). All patients underwent a complete ophthalmological assessment, including visual acuity and RNFL, neurological evaluation, orbits MRI. Segmentation of the optic nerves was performed through 3D slicer open software to get radiomics analysis. All patients underwent a complete neuro-ophthalmological follow-up at 6months to assess the VO, classified as complete recovery, partial recovery, deficit persistence/relapse, or visual worsening and were diagnosed as MS or clinically isolated syndrome.
 
  We observed significant correlations between radiomic features and RNFL and between radiomic features and VA. Regression model analysis identified 1 radiomic feature with significant association with VO (Gray Level non-uniformity Normalized, p = 0.004) and 6 radiomic features with significant correlation with diagnosis (High Gray Level Zone Emphasis, p < 0.001; Entropy, p < 0.001, for T1 segmentation; Mean Absolute Deviation, p < 0.001; Coarseness < 0.001; Small Area Low Gray Level Emphasis, p < 0.001; Contrast, p = 0.008, for STIR segmentation).
 
  Orbits MRI analysis at the first episode of ON has the potential to assess the visual function and VO in ON patients, and predict MS development.

  To evaluate the characteristics of mental health presentations to the emergency department in two different hospital settings.
 
  This was a retrospective cross-sectional study examining ED referrals to psychiatry in an inner-city and suburban centre. The authors collected data on gender, age, employment, housing, clinical presentation, time of assessment and admissions, over a 1-month period.
 
  The total number referred was 213 inner-city n = 109 and suburban n = 104.  https://www.selleckchem.com/  The inner-city saw a younger population; 47/109 (43%) were aged between 20 and 29years, compared with 28/104 (27%) of suburban presenters (P value 0.0134). A higher number of presenters were aged over 60 in the suburban centre n = 13/104 (12.5%) versus the inner-city centre 3/109 (2.8%) (P value 0.0084). In the inner-city, the proportion of homeless presenters was significantly higher at 30/109 (28%) versus 5/104 (4.8%) in the suburban setting (P < 0.0001). Presentations related to substances were highest, a total of 73 (34.3%) across both centres, with no significant difference in clinical presentations across the two centres.
