Abstract
Thismanuscript focuses on the physiological, environmental, nutritional, circadian, and aging factors affecting skin tissue water and hydration parameters. The literature findings indicate a multiplicity of interacting processes among these parameters, ultimately impacting skin hydration in normal skin and playing a role in conditions such as atopic dermatitis and psoriasis. The maintenance of adequate skin hydration, aided by the proper functioning of the skin’s protective barrier, is facilitated by stratum corneum integrity with the presence of tight junctions and lipids such as ceramides, each of which is impacted by changes in most of the evaluated parameters. Abnormalities in aquaporin 3 (AQP3) expression and associated deficits in skin hydration appear to have a role in atopic dermatitis and psoriasis. AQP3 hydration-related aspects are influenced by circadian rhythms via modulations associated with CLOCK genes that alter AQP3 protein expression. Ultraviolet exposure, aging, and low temperatures are among those factors that affect skin ceramide composition, potentially leading to increased transepidermal water loss and negatively impacting skin hydration. Vitamin C, collagen, and probiotics may increase ceramide production and improve skin hydration. The extent to which each of the different evaluated factors affects skin hydration varies but is usually large enough to consider their potential effects when investigating skin in research and clinical settings.

Abstract
Background and study aims The use of fluoroscopy during pregnancy should be minimized given that a clear-cut safe radiation dose in pregnancy is unknown. The role of digital single-operator cholangioscopy (D-SOC) as an alternative to standard enodoscopic retrograde cholangiopancreatography (ERCP) in pregnant patients has not been comprehensively studied. This study assessed 1 Technical success defined as performance of ERCP with D-SOC without the use of fluoroscopy in pregnant patients; 2 safety of D-SOC in pregnancy; and 3 maternal and neonatal outcomes after D-SOC during/after pregnancy. Patients and methods This was an international, multicenter, retrospective study at 6 tertiary centers. Pregnant patients who underwent D-SOC for the treatment of bile duct stones and/or strictures were included. Results A total of 10 patients underwent D-SOC. Indications for ERCP were choledocholithiasis, strictures, previous stent removal, and choledocholithiasis/stent removal. Bile duct cannulation without fluoroscopy was achieved in 10 of 10 patients (100 %). Moreover, 50 % of patients (5/10) completed a fluoroless ERCP with D-SOC. Mean fluoroscopy dose and fluoroscopy time were 3.4 ± 7.2 mGy and 0.5 ± 0.8 min, respectively. One case of mild bleeding and one case of moderate post-ERCP pancreatitis occurred. The mean gestational age at delivery was 36.2 ± 2.6 weeks. Median birth weight was 2.5 kg [IQR: 2.2-2.8]. No birth defects were noted. Conclusion ERCP guided by D-SOC appears to be a feasible and effective alternative to standard ERCP in pregnant patients. It enables avoidance of radiation in half of cases.
