Dear Editor,Three dimensional(3D)bioprinted extracellular matrix(ECM)can be used to provide both biochemical and biophysical cues to direct mesenchymal stem cells(MSCs)differentiation,and then differentiated cells were isolated for implantation in vivo using surgical ***,the reduced cell activity after cell isolation from 3D constructs and low cell retention in injured sites limit its application[1].Methacrylated gelatin(GelMA)hydrogel has the advantage of fast crosslinking,which could resemble complex architectures of tissue construct in vivo[2].Here,we adopted a noninvasive bioprinting procedure to imitate the regenerative microenvironment that could simultaneously direct the sweat gland(SG)and vascular differentiation from MSCs and ultimately promote the replacement of glandular tissue in situ(Fig.1a).

Purpose:The aim of the study was to examine the influence of the surgical approach for robot-assisted laparoscopic prostatectomy(RALP)on long-term urinary continence status in the era of self-reported functional status measures using the Expanded Prostate Can-cer Index Composite 26.Materials and methods:This is a prospective evaluation of 232 patients undergoing RALP between September,2019 and September,*** continence status and postoperative incontinence(pad usage)were evaluated 12 months after RALP using Expanded Prostate Cancer Index Composite 26 *** were categorized according to their surgical approach and outcome into the following groups:successful nerve sparing(NS),primarily without nerve sparing(***),and no nerve sparing by secondary resection(NNS by SR).The median levels of their questionnaire outcomes were evaluated and compared using the Wilcoxon rank sum test with continuity correction.Results:Urinary continence status 12 months after RALP differed significantly between the NS and ***(p=0.0071)and the NS and NNS by SR(p=0.0076)*** was no significant difference between the *** and NNS by SR(p=0.53)*** usage 12 months after RALP had no significant difference with regard to SR of the neurovascular bundle(p=0.14).Conclusions:Patient-reported outcomes of long-term urinary continence status seem to show no difference in postoperative conti-nence,regardless of whether a non-nerve-sparing result was planned or reached through ***,preservation of neurovascular bundle seems to lead to better long-term continence rates.

Introduction: Despite advances in obstetrics and pediatrics over the past 20 years, premature birth remains an unpredictable event that can have a devastating impact on parenthood. This study aimed to analyze the psycho-affective experiences of fathers of premature newborns. Methods: This was a descriptive cross-sectional study, carried out in the department of neonatology and neonatal intensive care unit of the CHU Mohamed VI in OUJDA, over 6 months from March 2022 to August 2022. It focused on 30 fathers of premature newborns hospitalized in our department. Results: The majority of fathers described a state of fear and stress, and attributed their negative experience to the unexpected nature of the premature birth. At the first meeting, half the fathers had a positive image of their newborn’s physical appearance, while 22% of fathers reported feeling uncomfortable about their newborn’s low weight. Most fathers reported that they appreciated the welcome they received, the skill with which they cared for their newborn, and the availability of the pediatrician to provide information on their child’s state of health. Two fathers enjoyed skin-to-skin contact with their newborns. None of the fathers met a psychologist. When they returned home, half the fathers had a positive outlook, marked by happiness at being able to fully invest in their role as fathers, the other half reported being torn between the desire to see their child integrated into the family cocoon and the fear of not being able to manage delicate situations properly without a medical team. Conclusion: Bringing a premature baby into the world can be a difficult experience, leading to the development of even minor psychological distress in some fathers, and hence the need for specific psychological care.
