Unraveling the brain control of metabolism may generate opportunities to discover novel precision medicines for obesity and diabetes. In this issue of Neuron, Liu et al. (2017) identify a novel glucagon-like peptide (GLP)-1 receptor-dependent signaling process that exerts anorexigenic action via the regulation of AMPA receptor subunit composition in the hypothalamus.

The objective of this work is to describe a segmental maxillary distraction osteogenesis (SDO) with segmental Lefort I with an inexpensive device.Four patients who presented severe class III and maxillary hypoplasia due to cleft lip and palate sequel were treated. A SDO was performed using a dental-anchored Hyrax device, achieving enlargement of the upper jaw without altering speech, with adequate and stable occlusion. Dental implants in a new formed bone were installed.The authors can conclude that SDO is a good treatment alternative for patients with maxillary hypoplasia...

PURPOSE: The distinction between physiologic (innocent) and pathologic (organic) heart murmurs is not always easy in routine practice, leading too often to unnecessary cardiology referrals and expensive investigations. We aimed to test the hypothesis that the complete disappearance of murmur on standing can exclude cardiac disease in children. METHODS: From January 2014 to January 2015, we prospectively included 194 consecutive children aged 2 to 18 years who were referred for heart murmur evaluation to pediatric cardiologists at 2 French medical centers...

Kevin C Lee, Michael Perrino
A major objective of orthognatic surgery is the aesthetic outcome. Treatments only correcting for dentoskeletal deformities are not sufficient for optimal facial results because undesirable soft tissue changes may accompany skeletal manipulations. The primary objective of this study was to investigate alar base width (ABW) changes a minimum of 6 months following surgically-assisted rapid palatal expansion (SARPE). The following electronic databases and citation indices were searched: PubMed, Cochrane Library, Scopus, Web of Science, Embase, and Virtual Health Library...

BACKGROUND: Orthognathic surgery is associated with considerable swelling and neurosensory disturbances. Serious swelling can lead to great physical and psychological strain. A randomized, prospective, controlled clinical trial was realized in order to evaluate the effect of a preoperative intravenous dexamethasone injection of 40 mg on postoperative swelling and neurosensory disturbances after orthognathic surgery. METHODS: Thirty-eight patients (27 male and 11 female) patients, all with the indication for an orthognathic surgery, were enrolled in this study (mean age: 27...

Schizophrenia is a devastating mental disease with an apparent disruption in the highly associative default mode network (DMN). Interplay between this canonical network and others probably contributes to goal-directed behavior so its disturbance is a candidate neural fingerprint underlying schizophrenia psychopathology. Previous research has reported both hyperconnectivity and hypoconnectivity within the DMN, and both increased and decreased DMN coupling with the multimodal saliency network (SN) and dorsal attention network (DAN)...

Riwal Lefort, Rémi Emmetière, Sabrina Bourmani, Gaultier Real, Angélique Drémeau
This paper deals with the loss of coherence in underwater direction-of-arrival estimation. The coherence loss, which typically arises from dynamical ocean fluctuations and unknown environmental parameters, may take the form of a multiplicative colored random noise applied to the measured acoustic signal. This specific multiplicative noise needs to be addressed with methodological developments. This paper proposes a weighting process that locally mitigates the effects of the coherence loss. More specially, a set of coherent sub-antennas is designed from the so-called Mutual Coherence Function (MCF)...

Background: Prosthetic valve endocarditis caused by Candida spp. (PVE-C) is rare and devastating, with international guidelines based on expert recommendations consisting in the combination of surgery and subsequent azole treatment. Methods: PVE-C collected in Spain and France between 2001 and 2015 were retrospectively analyzed with a focus on management and outcome. Results: Forty-six cases were followed up for a median of 9 months. Twenty-two (48%) patients had a past history of endocarditis; 30 (65%) cases were nosocomial or healthcare-related, 9 (20%) patients were intravenous drug users...

Due to the complex development of the craniofacial skull, corrective surgery is a major challenge for patients with severe craniofaciostenosis. Although fronto-orbital advancement and simultaneous LeFort-III osteotomy in combination with distraction osteogenesis have been reported as a safe and successful method to obtain good esthetic and functional results, there is a lack of studies evaluating this method.Our retrospective study included 12 patients with syndromic craniofaciostenosis, who were primarily treated at our department in accordance with a standardized treatment protocol, consisting of a simultaneous fronto-orbital advancement with LeFort-III osteotomy in combination with a rigid external distractor (RED-II)...

Anaerobic digestion is a common method for reducing the amount of sludge solids in used waters and enabling biogas production. The wet oxidation process (WOX) improves anaerobic digestion by converting carbon into methane through oxidation of organic compounds. WOX produces effluents rich in ammonia, which must be removed to maintain the activity of methanogens. Ammonia removal from WOX could be biologically operated by aerobic granules. To this end, granulation experiments were conducted in 2 bioreactors containing an activated sludge (AS)...

The concept of damage control (DC) is based on a sequential therapeutic strategy that favors physiological restoration over anatomical repair in patients presenting acutely with hemorrhagic trauma. Initially described as damage control surgery (DCS) for war-wounded patients with abdominal penetrating hemorrhagic trauma, this concept is articulated in three steps: surgical control of lesions (hemostasis, sealing of intestinal spillage), physiological restoration, then surgery for definitive repair. This concept was quickly adapted for intensive care management under the name damage control resuscitation (DCR), which refers to the modalities of hospital resuscitation carried out in patients suffering from traumatic hemorrhagic shock within the context of DCS...

Catecholamine (CA) secretion from the adrenal medullary tissue is a key step of the adaptive response triggered by an organism to cope with stress. Whereas molecular and cellular secretory processes have been extensively studied at the single chromaffin cell level, data available for the whole gland level are much scarcer. We tackled this issue in rat by developing an easy to implement experimental strategy combining the adrenal acute slice supernatant collection with a high-performance liquid chromatography-based epinephrine and norepinephrine (NE) assay...

Simple and non-invasive, the electrocardiogram is a basic examination for studying how the cardiac muscle functions. Very commonly used, it nonetheless requires great rigour when applying the electrodes to avoid false results that can be harmful to appropriate care for the patient. A reminder of good practices.

BACKGROUND: The clinical management of thyroid nodules with indeterminate cytology (IC) remains challenging. The role of shear wave elastography (SWE) in this setting is controversial. The aim of the study was to assess the performances of SWE in terms of prediction of malignancy, reproducibility, and combined analysis with ultrasound (US) examination in thyroid nodules with IC. METHODS: This prospective study was conducted in two referral centers. Eligible patients had a thyroid nodule ≥15 mm with IC (Bethesda class III-V) for which surgery had been recommended...

BACKGROUND: The purpose of orthognathic surgery is to correct facial deformity and dental malocclusion and to obtain normal orofacial function. However, there are controversies of whether orthognathic surgery might have any negative influence on temporomandibular (TM) joint. The purpose of this study was to evaluate the influence of orthognathic surgery on articular disc position and temporomandibular joint symptoms of skeletal CI II patients by means of magnetic resonance imaging. MATERIAL AND METHODS: For this purpose, fifteen patients with skeletal CI II malocclusion, aged 19-32 years (mean 23 years), 10 women and 5 men, from the Isfahan Department of Oral and Maxillofacial Surgery were studied...

Cutaneous squamous cell carcinoma (SCC) is the second most common human skin cancer with a rapidly increasing incidence among the Caucasian population. Among the many regulators, responsible for cancer progression and growth, microRNAs (miRNA) are generally accepted as key players by now. In our current study we found that microRNA-181a (miR-181a) shows low abundance in SCC compared to normal epidermal skin. In vitro, miRNA downregulation in normal primary keratinocytes induced increased proliferation, while in vivo miR-181a downregulation in HaCaT normal keratinocytes showed tumor-like growth increase up to 50%...
