Abstract

The Cartesian coordinate system is the most commonly used system in computer visualization. This is due to its ease of use and processing speed. However, it is not always suitable for a given problem. Angular measures often allow us to operate more efficiently on a three-dimensional model. When dealing with issues related to the processing of three-dimensional objects described using polygon meshes, it often happens that these standard systems do not satisfy specific properties that are crucial to us. The topic of the paper is to discuss a specific transformation to spherical coordinates with distorted poles, which allows us to eliminate singular points from the determined subset of the mesh and bypass inconvenient seam lines in its two-dimensional projection, which can hinder further calculations., Comment: 10 pages, 5 figures, submitted to 30th INTERNATIONAL CONFERENCE ON SYSTEMS ENGINEERING, ICSEng 2023, Las Vegas, NV, USA, August 22-24, 2023

Abstract

Introduction: COVID-19 is a prominently respiratory infection, with potential renal complications. Our objective was to describe the incidence of renal impairment and its influence on clinical outcome in patients admitted to University Hospital No 1 in Bydgoszcz due to COVID-19. Material and methods: In this single-center observational study we retrospectively identified patients with a positive test result for SARS-CoV-2 from either a nasopharyngeal or oropharyngeal swab PCR (n = 988) who were admitted to University Hospital No 1 in Bydgoszcz, Poland since April 1, 2020 to April 30, 2021. Details of the patients' demographics, diagnoses (based on ICD-10 codes), eGFR and clinical outcomes were obtained using a combination of a manual chart review of the electronic medical record from the hospital database. Results: Median baseline eGFR was 77,4 ml/min (IQR 51,6-93,7 ml/min) and minimal eGFR was 68,7 ml/min (IQR 39,9-90 ml/min), p < 0,05. We found significant differences in median baseline and minimal eGFR between patients discharged and deceased (80,8 vs. 55,4 ml/min and 73,7 vs. 33 ml/min, respectively, p < 0,001). Patients who died (12,5 %) were older, with more co-morbidities including CKD and AKI, and presented a significantly lower value of eGFR both at baseline and during hospital stay, as well as, more frequent and extensive deterioration of eGFR. Factors predisposing to in-hospital death were age, atrial fibrillation, heart failure, coronary artery disease, and among them AKI and CKD were strong negative prognostic parameters. Conclusions: Renal impairment on admission as well as during hospitalization among patients with SARS-CoV-2 infection is a risk factor of negative outcome. [ABSTRACT FROM AUTHOR]

Abstract

Introduction: The Sinclair Scale of hair midline density is commonly used in clinical dermatology practice as a tool to evaluate the severity of female pattern hair loss (synonym androgenetic alopecia, AGA) and to monitor patient response to treatment. The Sinclair Scale involves a visual evaluation of central hair parting line width, that is performed quickly and with no optical instrumentation. Another approach used to score severity of hair loss is quantitative trichoscopy. While quantitative trichoscopy is more accurate in terms of reproducibility and objectivity, it is more time‐consuming. Materials and Methods: Patients with different stages of AGA were evaluated using both the Sinclair Scale and quantitative trichoscopy. A correlation analysis was performed between the Sinclair Scale and different parameters derived from statistical analysis of trichoscopy images. A novel parameter, cumulative hair thickness density was introduced. Results: Very good correlation was observed between Sinclair Scale and the cumulative hair thickness density. The quality of correlation is sufficient to estimate Sinclair Scale from cumulative hair thickness density. A formula to calculate the 'Trichoscopy Derived Sinclair Scale' from trichoscopy statistics was derived. Discussion: We propose the term 'Trichoscopy Derived Sinclair Scale' to describe the hair midline density as derived from trichoscopy and to differentiate this assessment of midline hair density from the traditional one based on visual inspection alone.

24. Sublingual Minoxidil Increases Fibre Diameter in Male Androgenetic Alopecia. - A proxy for Reversal of Hair Follicle Miniaturization.

Author

Sinclair R, Sicinska J, Bokhari L, and Kasprzak M

Abstract

Background: The histological hallmark of male androgenetic alopecia (MAGA) is transformation of terminal follicles into miniaturized secondary-vellus follicles. As the volume of the dermal papilla determines the size of the hair bulb and hair fibre diameter, any treatment induced increase in fibre diameter could be used as a proxy for reversal of hair follicle miniaturization. While clinical trials with minoxidil topical solution in MAGA do not demonstrate increased fibre diameter, vellus-to-terminal reconversion is shown in a humanized mouse model treated with MXL., Objective: To investigate whether low-dose, sub-lingual minoxidil (SLM) increases hair fibre diameter in MAGA., Method: Serial, tattoo-localized phototrichograms were analyzed using hair-to-hair (H2H) matching software in 33 patients with MAGA who participated in a 24-week randomized, double-blinded, placebo controlled, clinical trial with SLM 0.45mg once daily. Additional data was obtained from 12 participants who had used placebo and then rolled into 6 months, open-label, extension study with either once daily 1.35mg or 4.05mg SLM.TrichoLAB® H2H analysis uniquely identified individual hairs and measured hair fibre diameter at baseline and 24 weeks., Results: After 24 weeks, fibre diameter decreased by 2±1µm (1σ CL) in men receiving placebo. The decrease was most marked in intermediate diameter fibres with a baseline diameter of 40-60µm.Among men receiving SLM 0.45mg, 1.35mg and 4.05 mg, the change in mean fibre diameter was: 2±1µm, 3±1µm, 6±1µm (1σ CL) respectively. Intermediate thickness fibres enlarged most.H2H matching demonstrated increased diameter in individual fibres., Conclusion: The effect of SLM on mean fibre diameter was dose-dependent. SLM 1.35mg and 4.05mg, but not 0.45mg, significantly increased mean fibre diameter in MAGA. Diameter increased most in intermediate and thickest hairs. This increase in fibre diameter infers reversal of follicle miniaturization in MAGA and is consistent with the observation of vellus-to-terminal reconversion is shown in a humanized mouse model treated with minoxidil., (© The Author(s) 2025.
