To report our novel technique and mid-term follow-up for robotic-assisted laparoscopic vaginectomy (RALV), a component procedure of staged gender-affirming penile reconstructive surgery.
The records of patients seeking gender-affirming penile reconstructive surgery who underwent RALV, performed by a single surgeon at our institution, between May 2016 and January 2020 were reviewed retrospectively for demographic and perioperative data. Patients were included irrespective of history of previous phalloplasty. A subset of these patients elected to have urethral lengthening during second stage phalloplasty for which an anterior vaginal mucosa flap urethroplasty was performed. Postoperative complications and outcomes and most recent follow-up were obtained.
A total of 42 patients were reviewed, of whom 19 (45%) patients ultimately had radial forearm free flap, 15 (41%) had anterolateral thigh flap, 5 (12%) had metoidioplasty, and 1 (2.4%) had abdominal phalloplasty. A vaginal mucosa and gracilis flap was used in all of 36 (86%) patients in whom a pars fixa was created. Average operative time was 299 minutes (range 153-506). Median estimated blood loss was 200 mL (range 100-400). Median length of stay was 3 days (range 1-7). Complications within 30 days from surgery occurred in 15 patients (36%), of whom 12/15 were Clavien-Dindo grade 1 or 2, and 11/15 had complications unrelated to vaginectomy. Of the 4 patients who had vaginectomy-related complications, all resolved with conservative management. Median overall follow-up was 15.8 months.
RALV offers a safe and efficient approach during staged gender-affirming penile reconstruction and may mitigate the subsequent risk of urethral complications.

To describe the infrapubic approach to penile prosthesis insertion in transmen after phalloplasty.
After verifying phalloplasty vascular pedicle anatomy and reliable micturition, patients may be considered for implant surgery. find more Specific modifications of the infrapubic approach to penile prosthesis insertion as well as individualization of commercially available implants are performed intraoperatively to help reduce the risk of postoperative complications.
In our single surgeon series (MLC) using the infrapubic approach with these specific implants after phalloplasty, 17/107 (16%) patients from October 2017 to November 2020 required revision surgery after mean follow-up of 79.8 weeks.

Here we investigated the effect of chemerin on the food and water consumption and on the body weight in chicken. We studied the effects on the plasma glucose and insulin concentrations and the hypothalamic neuropeptides and AMPK signaling pathway. Female broiler chickens were intraperitoneally injected, daily for 13 days with either vehicle (saline; n = 25) or chemerin (8 μg/kg; n = 25 and 16 μg/kg; n = 25). Food and water intakes were recorded 24 h after each administration. Overnight fasted animals were sacrificed at day 13 (D13), 24 h after the last injection and hypothalamus and left cerebral hemispheres were collected. Chemerin and its receptors protein levels were determined by western-blot. Gene expression of neuropeptide Y (Npy), agouti-related peptide (Agrp), corticotrophin releasing hormone (Crh), pro-opiomelanocortin (Pomc), cocaine and amphetamine-regulated transcript (Cart) and Taste 1 Receptor Member 1 (Tas1r1) were evaluated by RT-qPCR. In chicken, we found that the protein amount of chemerin, CCRL2 and GPR1 was similar in left cerebral hemisphere and hypothalamus whereas CMKLR1 was higher in hypothalamus. Chemerin administration (8 and 16 μg/kg) decreased both food intake and body weight compared to vehicle without affecting water intake and the size or volume of different brain subdivisions as determined by magnetic resonance imaging. It also increased plasma insulin levels whereas glucose levels were decreased. These data were associated with an increase in Npy and Agrp expressions and a decrease in Crh, Tas1r1 mRNA expression within the hypothalamus. Furthermore, chemerin decreased hypothalamic CMKLR1 protein expression and AMPK activation. Taken together, these results support that chemerin could be a peripheral appetite-regulating signal through modulation of hypothalamic peptides expression in chicken.Thyroid hormones (THs) are instrumental in promoting the molecular mechanisms which underlie the complex nature of neural development and function within the central nervous system (CNS) in vertebrates. The key neurodevelopmental process of myelination is conserved between humans and rodents, of which both experience peak fetal TH concentrations concomitant with onset of myelination. The importance of supplying adequate levels of THs to the myelin producing cells, the oligodendrocytes, for promoting their maturation is crucial for proper neural function. In this review we examine the key TH distributor and transport proteins, including transthyretin (TTR) and monocarboxylate transporter 8 (MCT8), essential for supporting proper oligodendrocyte and myelin health; and discuss disorders with impaired TH signalling in relation to abnormal CNS myelination in humans and rodents. Furthermore, we explore the importance of using novel TH analogues in the treatment of myelination disorders associated with abnormal TH signalling.The gut-brain axis plays an important role in maintaining homeostasis. Many intrinsic and extrinsic factors influence signaling along this axis, modulating the function of both the enteric and central nervous systems. More recently the role of the microbiome as an important factor in modulating gut-brain signaling has emerged and the concept of a microbiota-gut-brain axis has been established. In this review, we highlight the role of this axis in modulating enteric and central nervous system function and how this may impact disorders such as irritable bowel syndrome and disorders of mood and affect. We examine the overlapping biological constructs that underpin these disorders with a special emphasis on the neurotransmitter serotonin, which plays a key role in both the gastrointestinal tract and in the brain. Overall, it is clear that although animal studies have shown much promise, more progress is necessary before these findings can be translated for diagnostic and therapeutic benefit in patient populations.
