OBJECTIVE: Current pharmacological agents used to treat Parkinson disease (PD) tremor and essential tremor (ET) provide suboptimal benefit and are commonly associated with significant adverse effects. Botulinum toxin type A (BoNT-A) has been shown to be effective for wrist tremor though functionally bothersome muscle weakness frequently occurs. This is the longest study to date demonstrating that BoNT-A therapy coupled with kinematic guidance can provide efficacious outcomes for upper limb tremor with minimized unwanted weakness...

OBJECTIVES: Selective circular myotomy (CM) is recommended in peroral endoscopic myotomy (POEM) for achalasia, but completeness of myotmoy is the prerequisite for excellent long-term results of conventional surgical myotomy. The aim of our study was to compare the efficacy and safety between peroral endoscopic full-thickness and simple CM for the treatment of severe achalasia. MATERIALS AND METHODS: A total of 123 severe achalasia patients who underwent POEM from August 2011 to May 2013 were included...

Gender dysphoria is estimated to occur in approximately 25 million people worldwide, and can have severe psychosocial sequelae. Medical and surgical gender transition can substantially improve quality-of-life outcomes for individuals with gender dysphoria. Individuals seeking to undergo female-to-male (FtM) transition have various surgical options available for gender confirmation, including facial and chest masculinization, body contouring, and genital surgery. The World Professional Association for Transgender Health guidelines should be met before the patient undergoes surgery, to ensure that gender-confirming surgery is appropriate and indicated...

After lesions of the CNS, locomotor abilities of animals (mainly cats) are often assessed on a simple flat treadmill (FTM) which imposes little demands on supraspinal structures as is the case when walking on targets. Therefore, the aims of the present work were 1) to develop a treadmill allowing the assessment of locomotion of intact cats required to place the paws on the rungs of a moving ladder treadmill (LTM); 2) to assess the capability of cats after a unilateral spinal hemisection at T10 to cope with such a demanding locomotor task; 3) to regularly train cats for 6wks on the LTM to see whether such regular training improves locomotor recovery on the FTM...

BACKGROUND: Disease assessment for recurrent glioblastoma (GBM) represents a challenge, especially with the use of antiangiogenic agents. Moreover, validated neuroradiological predictors of outcome are lacking. Recently, the concept of early tumor shrinkage (ETS) has been developed to better assess the ability of treatments in determining a rapid and remarkable tumor response.The aim of the study was to evaluate the role of ETS in predicting survival of GBM patients treated with BEVMETHODS: We examined the radiological data of patients with recurrent GBM treated with bevacizumab (BEV) or fotemustine (FTM) in the randomized phase II AVAREG trial (EudraCT: 2011-001363-46)...

BACKGROUND: Subcutaneous mastectomy for female- to-male transsexuals is usually the first surgical pro- cedure in sexual reassignment. The main objective of subcutaneous mastectomy is to create an aesthetically pleasing male chest contour by removing all glandular tissue while minimizing chest wall scars. AIMS: In this paper, we present our experience with subcutaneous mastectomy performed in female-to- male transsexual patients. The authors recommend their point of view to aid in selecting the most suitable subcutaneous mastectomy technique depending on breast characteristics...

OBJECTIVE Unilateral Gamma Knife thalamotomy (GKT) is a well-established treatment for patients with medically refractory tremor who are not eligible for invasive procedures due to increased risk of compications. The purpose of this study was to evaluate whether staged bilateral GKT provides benefit with acceptable risk to patients suffering from disabling medically refractory bilateral tremor. METHODS Eleven patients underwent staged bilateral GKT during a 17-year period (1999-2016). Eight patients had essential tremor (ET), 2 had Parkinson's disease (PD)-related tremor, and 1 had multiple-sclerosis (MS)-related tremor...

Liver fatty acid binding protein (Fabp1) and sterol carrier protein-2/sterol carrier protein-x (SCP-2/SCP-x) genes encode proteins that enhance hepatic uptake, cytosolic transport, and peroxisomal oxidation of toxic branched-chain fatty acids derived from dietary phytol. Since male wild-type (WT) mice express markedly higher levels of these proteins than females, the impact of ablating both genes (TKO) was examined in phytol-fed males. In WT males, high phytol diet alone had little impact on whole body weight and did not alter the proportion of lean tissue mass (LTM) versus fat tissue mass (FTM)...

Context: Testosterone is commonly administered intramuscularly (IM) to treat hypogonadal males and female-to-male transgender (FTM) patients. However, these injections can involve significant discomfort and may require arrangements for administration by others. Objective: We assessed whether T could be administered effectively and safely by the subcutaneously (SC) as an alternative to IM injections. Design: Retrospective cohort study. Setting: Outpatient Reproductive Endocrinology Clinic at an academic medical center...

BACKGROUND: Fistulas are the preferred permanent hemodialysis vascular access, but a significant obstacle to increasing their prevalence is the fistula's high "failure to mature" (FTM) rate. This study aimed to identify postoperative clinical characteristics that are predictive of fistula FTM. MATERIALS AND METHODS: This descriptive cross-sectional study was performed on 80 end-stage renal disease patients who referred to Al Zahra Hospital, Isfahan, for brachiocephalic fistula placement...

Tunable diode laser absorption spectroscopy (TDLAS) was evaluated on its potential to detect bacterial growth of contaminated media fill vials. The target was a replacement/ automation of the traditional visual media fill inspection. TDLAS was used to determine non-invasively O2 and/or CO2 changes in headspaces of such vials being induced by metabolically active microorganisms. Four different vial formats, 34 microorganisms (inoculation volume<10 cells) and two different media (TSB/FTM) were tested. Applying parallel CO2 and O2 headspace measurements all format-organism combinations were detected within <11 days reliably with reproducible results...

Full thickness human skin models (FTMs) contain an epidermal and a dermal equivalent. The latter is composed of a collagen dermal matrix which harbours fibroblasts. Current epidermal barrier properties of FTMs do not fully resemble that of native human skin (NHS), which makes these human skin models less suitable for barrier related studies. To further enhance the resemblance of NHS for epidermal morphogenesis and barrier formation, we modulated the collagen dermal matrix with the biocompatible polymer chitosan...

OBJECTIVE: The biologic basis for gender identity is unknown. Research has shown that the ratio of the length of the second and fourth digits (2D:4D) in mammals is influenced by biologic sex in utero, but data on 2D:4D ratios in transgender individuals are scarce and contradictory. We investigated a possible association between 2D:4D ratio and gender identity in our transgender clinic population in Albany, New York. METHODS: We prospectively recruited 118 transgender subjects undergoing hormonal therapy (50 female to male [FTM] and 68 male to female [MTF]) for finger length measurement...

INTRODUCTION: Brescia-Cimino radiocephalic arteriovenous fistula (AVF) remains the first-choice vascular access procedure for patients in need of long-term hemodialysis. The average life expectancy of patients receiving hemodialysis has increased in recent years and many patients now live longer and require secondary or tertiary procedures. Elbow fistulas should only rarely be constructed as primary fistulas. The aim of the surgeon must be not only to achieve a functioning fistula, but to avoid possible complications other than failure to mature (FTM), like distal ischemia and cardiac failure and to save the vessels as much as possible for future procedures...

INTRODUCTION: The arteriovenous fistula (AVF) is the preferred vascular access for hemodialysis patients. Unfortunately, 20-40% of all constructed AVFs fail to mature (FTM), and are therefore not usable for hemodialysis. AVF maturation importantly depends on postoperative blood volume flow. Predicting patient-specific immediate postoperative flow could therefore support surgical planning. A computational model predicting blood volume flow is available, but the effect of blood flow predictions on the clinical endpoint of maturation (at least 500 mL/min blood volume flow, diameter of the venous cannulation segment ≥4 mm) remains undetermined...

In recent years, different studies have provided estimates of the prevalence of transsexualism with very diverse results. The purpose of this study was to ascertain the prevalence, incidence, and sex ratio of transsexualism in the autonomous region of Madrid (Spain). A total of 1234 patients who attended from 2007 to the end of 2015 in the only Gender Identity Unit (GIU) in Madrid were analyzed. Sixty-three patients were excluded for various reasons; thus, 1171 could be included: 803 male-to-female (MtF) and 368 female-to-male (FtM) transsexual patients...

BACKGROUND: First trimester (FTM) and term human umbilical cord-derived perivascular cells (HUCPVCs), which are rich sources of mesenchymal stem cells (MSCs), can give rise to Sertoli cell (SC)-like as well as haploid germ cell (GC)-like cells in vitro using culture conditions that recapitulate the testicular niche. Gamete-like cells have been produced ex vivo using pluripotent stem cells as well as MSCs. However, the production of functional gametes from human stem cells has yet to be achieved...

Giulia Lo Russo, Sara Tanini, Marco Innocenti
BACKGROUND: Chest-wall contouring surgery is one of the first steps in sexual reassignment in female-to-male (FtM) transsexuals that contributes to strengthening of the self-image and facilitates living in the new gender role. The main goal is to masculinize the chest by removing the female contour. Chest contour, scar placement, scar shape, scar length, nipple-areola position, nipple size and the areola size are the key points. METHODS: Between July 2013 and June 2016, 25 FtM transgender patients underwent surgical procedures to create a masculine chest-wall contour...

INTRODUCTION: Gender dysphoria, a marked incongruence between one's experienced gender and biological sex, is commonly believed to arise from discrepant cerebral and genital sexual differentiation. With the discovery that estrogen receptor β is associated with female-to-male (FtM) but not with male-to-female (MtF) gender dysphoria, and given estrogen receptor α involvement in central nervous system masculinization, it was hypothesized that estrogen receptor α, encoded by the ESR1 gene, also might be implicated...

Extracting local features from 3D shapes is an important and challenging task that usually requires carefully designed 3D shape descriptors. However, these descriptors are hand-crafted and require intensive human intervention with prior knowledge. To tackle this issue, we propose a novel deep learning model, namely Circle Convolutional Restricted Boltzmann Machine (CCRBM), for unsupervised 3D local feature learning. CCRBM is specially designed to learn from raw 3D representations. It effectively overcomes obstacles such as irregular vertex topology, orientation ambiguity on the 3D surface, and rigid or slightly non-rigid transformation invariance in the hierarchical learning of 3D data that cannot be resolved by the existing deep learning models...
