We present a series of three kidney transplant patients developing epidermoid cysts after receiving oral tacrolimus for long-term prevention of rejection of the allograft. Cyclosporin A has been known to show this cutaneous adverse drug reaction, but this is the first series of patients with epidermoid cysts following tacrolimus to the best of our knowledge. © 2020 Wiley Periodicals, Inc.The use of the tetrabutylammonium additive was investigated in the ultra-high performance reversed-phase liquid chromatographic elution of basic molecules of pharmaceutical interest. When added to the mobile phase at low pH, the hydrophobic tetrabutylammonium cation interacts with the octadecyl chains and with the residual silanols, thus imparting a positive charge to the stationary phase, modulating retention and improving peak shape of protonated basic solutes. Two sources of additive were tested a mixture of tetrabutylammonium hydroxide/trifluoroacetic acid and tetrabutylammonium hydrogen sulfate. Retention and peak shape of 11 basic pharmaceutical compounds were evaluated on commercially available ultra-fast columns packed with octadecyl stationary phases (Ascentis Express C18 2.0 µm, Acquity BEH C18 1.7 µm, Titan C18 1.9 µm). All columns benefit from the use of additive, especially tetrabutylammonium hydrogen sulfate, providing very symmetric peaks with reasonable retention times. Focusing on the probe compounds amitriptyline and sertraline, efficiency and asymmetry values were investigated at increasing retention factor. The trend is very different to that obtained in reversed-phase conditions and the effect lies in the complex molecular interaction mechanisms based on hydrophobic and ion exchange interactions as well as electrostatic repulsion. © 2020 WILEY-VCH Verlag GmbH & Co.

There is limited evidence on the impact of dysnatraemia on outcomes such as length of stay (LOS) and intensive care unit (ICU) admission. AIMS This study aimed to investigate the relationship between admission sodium levels at a quaternary referral hospital and outcomes including mortality, LOS and admission to ICU. METHODS All patients admitted to hospital over a period of one year who had a blood sodium level measured on admission were included. Admission sodium levels and related blood results were obtained. Data linkage was performed. Analyses for associations between admission sodium level and primary hospital outcomes (in-hospital mortality) and secondary hospital outcomes (LOS and admission to ICU) were performed. Case notes of patients with severe hyponatraemia were also reviewed, with a focus on the use of hypertonic saline. RESULTS A total of 6447 patient admissions had an admission blood sodium level performed. Mean age was 55.8±20.8 years. 49.3% were male. Serum sodium ranged from 110 mmol/L to 175 mmol/L. The primary outcome of in-hospital mortality occurred in 190 patients. An abnormal sodium level (Na 145 mmol/L) was an independent predictor of in-hospital mortality, and an independent predictor of the combined outcome of in-hospital mortality and admission to ICU. Hypertonic saline was infrequently used in patients with severe hyponatraemia. Its use did not worsen outcomes. CONCLUSIONS An abnormal serum sodium level is a strong marker of poor outcome in acute hospital illness. This article is protected by copyright. All rights reserved.

METHODS Cognitive mapping (CM) was assessed in 95 participants and route learning (RL) was assessed in 65 participants at baseline. Clinical progression over an average of 4 to 5 years was assessed using the clinical dementia rating (CDR) scale. Relative predictive ability was compared to episodic memory, hippocampus, and cerebrospinal fluid biomarkers (phosphorylated tau/amyloid β 42 (ptau181 /Aβ42 ) ratio). RESULTS CM and RL were predictors of clinical progression (P's  less then  0.032). All measures, except RL-Learning remained predictors with episodic memory in models (P's  less then  0.048). Only RL-Retrieval remained a predictor when ptau181 /Aβ42 was included (P  less then  0.001). CM interacted with hippocampus and ptau181 /Aβ42 in prediction (P's  less then  0.013). CM, RL, and episodic memory evidenced strong diagnostic accuracy (area under the curve (AUC) = 0.894, 0.794, and 0.735, respectively); CM tended to perform better than episodic memory (P = 0.056). DISCUSSION Baseline spatial navigation performance may be appropriate for assessing risk of clinical progression. © 2019 the Alzheimer's Association.An organic crystal of 4,4'-bis(N-carbazolyl)-1,1'-biphenyl (pCBP) exhibits time-dependent afterglow color from blue to orange over 1 s. Both experimental and computational data confirm that the color evolution results from well-separated, long-persistent thermally activated delayed fluorescence (TADF) and room-temperature phosphorescence (RTP) with different but comparable decay rates. TADF is enabled by a small S1 -T1 energy gap of 0.7 kcal mol-1 . The good separation of TADF and RTP is due to a 11.8 kcal mol-1 difference in the S0 energies of the S1 and T1 structures, indicating that apart from the excited-state properties, tuning the ground state is also important for luminescence properties. This afterglow color evolution of pCBP allows its applications in anticounterfeiting and data encryption with high security levels. © 2020 Wiley-VCH Verlag GmbH & Co.

This partnership involves an exchange of medical information and information about patient/family preferences and values. Together, the health-care team, parent and patient deliberate to determine the best course of action for the child. Despite high-quality evidence supporting its positive impact on outcomes, SDM has not been widely adopted in paediatric clinical practice. Greater understanding of the impact of SDM on all members of the decision triad (parent, patient and health-care provider) may increase the likelihood of SDM adoption. Therefore, we present the viewpoints of a paediatric patient, parent and paediatrician about the use of SDM. A youth living with a rare chronic disease discusses the impacts of being involved and excluded from health decisions. A mother of a son living with a rare nephrotic condition discusses working with a health-care team who are committed and skilled in SDM and the positive impacts SDM has had for her son's care.
