Purpose Prostate cancer largely affects older men. This study aims to investigate prostate cancer in younger men ( less then 55 years) to shed light on the survival outcomes of this unique subset of patients in Asian context. Methods Data were obtained from the Singapore General Hospital Prostate Cancer Registry. Data on all men with clinically organ confined prostate cancer who underwent radical prostatectomy between 1998 and 2016 were obtained from the registry. Tumor characteristics, follow-up data, and cause of death were acquired. Results A total of 1120 men underwent radical prostatectomy between 1998 and 2016. Of these, 12 were aged ≤ 44 years, 106 were aged 45-54 years, 596 were aged 55-64, 397 were aged 65-74 and 9 were aged ≥ 75. There was no difference across age groups when comparing Gleason ≤ 7 vs Gleason ≥ 8 disease, T1/2 vs T3/4 disease and the median PSA values were similar. No difference was observed in overall survival or prostate cancer specific survival among 4 age groups (≤ 44, 45-54, 55-64, 65-74) (p = 0.156 and p = 0.227 respectively). Although there was a trend of increasing rate of biochemical recurrence for older patients, it's not statistically significant (p = 0.157). Time to biochemical recurrence was similar as well (p = 0.257). Conclusion This large cohort of Asian patients who underwent radical prostatectomy did not show significant age-related differences in important parameters and outcomes.This study investigates the association between the treatment with heparin and mortality in patients admitted with Covid-19. Routinely recorded, clinical data, up to the 24th of April 2020, from the 2075 patients with Covid-19, admitted in 17 hospitals in Spain between the 1st of March and the 20th of April 2020 were used. Caspase phosphorylation The following variables were extracted for this study age, gender, temperature, and saturation of oxygen on admission, treatment with heparin, hydroxychloroquine, azithromycin, steroids, tocilizumab, a combination of lopinavir with ritonavir, and oseltamivir, together with data on mortality. Multivariable logistic regression models were used to investigate the associations. At the time of collecting the data, 301 patients had died, 1447 had been discharged home from the hospitals, 201 were still admitted, and 126 had been transferred to hospitals not included in the study. Median follow up time was 8 (IQR 5-12) days. Heparin had been used in 1734 patients. Heparin was associated with lower mortality when the model was adjusted for age and gender, with OR (95% CI) 0.55 (0.37-0.82) p = 0.003. This association remained significant when saturation of oxygen 37 °C were added to de model with OR 0.54 (0.36-0.82) p = 0.003, and also when all the other drugs were included as covariates OR 0.42 (0.26-0.66) p less then 0.001. The association between heparin and lower mortality observed in this study can be acknowledged by clinicians in hospitals and in the community. Randomized controlled trials to assess the causal effects of heparin in different therapeutic regimes are required.Purpose Basal cell carcinoma (BCC) is the most commonly diagnosed skin cancer and is treated by surgical resection. Incomplete tumor removal requires surgical revision, leading to significant healthcare costs and impaired cosmesis. We investigated the clinical feasibility of a surgical navigation system for BCC surgery, based on molecular tissue characterization using rapid evaporative ionization mass spectrometry (REIMS). Methods REIMS enables direct tissue characterization by analysis of cell-specific molecules present within surgical smoke, produced during electrocautery tissue resection. A tissue characterization model was built by acquiring REIMS spectra of BCC, healthy skin and fat from ex vivo skin cancer specimens. This model was used for tissue characterization during navigated skin cancer surgery. Navigation was enabled by optical tracking and real-time visualization of the cautery relative to a contoured resection volume. The surgical smoke was aspirated into a mass spectrometer and directly analyzlogy-validated mass spectra.Purpose To compare retinal nerve fiber layer (RNFL), ganglion cell-inner plexiform layer (GC-IPL), the lamina cribrosa depth (LCD) and thickness (LCT) in unilateral exfoliative glaucoma (EXG) patients with their fellow eyes without exfoliation and control eyes. Methods This cross-sectional prospective single-center study consisted of 64 eyes of 32 patients with unilateral EXG and 35 eyes of controls. All subjects were examined with spectral domain optical coherence tomography for the RNFL and GC-IPL measurements. The LCD and LCT measurements were also obtained. Results The RNFL measurements at all quadrants were statistically thinner in EXG eyes than those in their eyes without EXG and control eyes (p less then 0.001 for average, superior, temporal and inferior; p = 0.004 for nasal). The EXG group had deeper LCD than their eyes without EXG and control eyes (p less then 0.001, for both). The fellow eyes of EXG group had also deeper LCD than control eyes, with no statistical significance (p = 0.058). The mean LCT was thinner in EXG eyes compared to those in the eyes without EXG and control eyes (p less then 0.001, for both). The eyes without EXG and control eyes had similar LCT (p = 0.293). Conclusions Recent developments in imaging technology give the clinician detailed structural information about optic nerve head and retina such as GC-IPL, LCD and LCT. In addition to follow-up of RNFL changes, these new parameters may be useful in recognizing progression in EXG patients.Cryptotanshinone (CPT) is an efficacious acne treatment, while niosomal hydrogel is a known effective topical drug delivery system that produces a minimal amount of irritation. Three-dimensional (3D) printing technologies have the potential to improve the field of personalized acne treatment. Therefore, this study endeavored to develop a 3D-printed niosomal hydrogel (3DP-NH) containing CPT as a topical delivery system for acne therapy. Specifically, CPT-loaded niosomes were prepared using a reverse phase evaporation method, and the formulation was optimized using a response surface methodology. In vitro characterization showed that optimized CPT-loaded niosomes were below 150 nm in size with an entrapment efficiency of between 67 and 71%. The CPT-loaded niosomes were added in a dropwise manner into the hydrogel to formulate CPT-loaded niosomal hydrogel (CPT-NH), which was then printed as 3DP-CPT-NH with specific drug dose, shape, and size using an extrusion-based 3D printer. The in vitro release behavior of 3DP-CPT-NH was found to follow the Korsmeyer-Peppas model.
