How to Build an Endobariatric Practice: Set Up, Branding, and Marketing.

In the last decade there has been significant development of novel devices and techniques in the field of endoscopic bariatric and metabolic therapies (EBMTs). Bariatric endoscopy fulfills an unmet need within the current paradigm of obesity management. The expansion of this field is an important step in offering complete care to patients with obesity and metabolic disease.

Stigma, Bias, and the Shortfalls of Body Mass Index: A Reflection on the State of Weight Management.

Obesity is a complex, multifactorial chronic disease. With the development of novel endoscopic techniques and devices for the treatment of obesity, combined with expanding indications for medications, gastroenterologists are more involved in weight management than ever before. Despite the modern definition of obesity as a disease, weight bias and stigma are pervasive in the medical community and beyond.

Major mixed motility disorders: An important subset of esophagogastric junction outflow obstruction.

Background: Esophagogastric junction outflow obstruction (EGJOO) is an esophageal motility disorder characterized by a lack of relaxation of the esophagogastric junction (EGJ), with preserved esophageal body peristalsis. We propose new terminology for the coexistence of EGJOO with hypercontractile esophagus and distal esophageal spasm as a major mixed motility disorder (MMMD), and normal peristalsis or a minor disorder of peristalsis such as ineffective esophageal motility with EGJOO as isolated or ineffective EGJOO (IEGJOO).

Methods: We reviewed prior diagnoses of EGJOO, stratified diagnoses as IEGJOO or MMMD, and compared their symptomatic presentations, high-resolution manometry (HRM) and endoluminal functional lumen imaging probe (EndoFLIP) metrics, and treatment responses at 2-6 months of follow-up.

Outcomes of Sleeve Gastrectomy at a Veterans Affairs Medical Center.

Bariatric surgery is the most effective treatment for obesity while improving comorbid conditions and decreasing mortality rates. The purpose of this analysis was to identify the predictive factors associated with the short-term outcomes of laparoscopic sleeve gastrectomy (LSG) at a single Veterans Affairs Medical Center (VAMC). This is a retrospective analysis of LSG performed at a VAMC from 2013 to 2019.

Mandibular micrognathia and vertical maxillary excess correction with combination LeFort I and inverted L osteotomies.

A 34-year-old woman with mandibular micrognathia, vertical maxillary excess, and an open bite characterized by a "bird-face" deformity was treated with orthodontics combined with LeFort I and bilateral inverted L osteotomies. The total treatment time was 16 months. Her occlusion and facial appearance were significantly improved by a surgical-orthodontic plan.

Subtle skills: Using objective structured clinical examinations to assess gastroenterology fellow performance in system based practice milestones.

Background: System based practice (SBP) milestones require trainees to effectively navigate the larger health care system for optimal patient care. In gastroenterology training programs, the assessment of SBP is difficult due to high volume, high acuity inpatient care, as well as inconsistent direct supervision. Nevertheless, structured assessment is required for training programs.

Anterior open bite due to idiopathic condylar resorption during orthodontic retention of a Class II Division 1 malocclusion.

A common dilemma when treating anterior open bite is understanding its etiology. Idiopathic condylar resorption (ICR) can cause open bite in affected individuals. Although it is prudent to not treat patients with ICR until active resorption has ceased, orthodontists may begin treating them because anterior open bite from ICR may not appear before or during their orthodontic treatment.

Anterior open bite correction with 2-jaw orthognathic surgery.

A 26-year-old man with an anterior open bite was treated with orthodontics combined with 2-jaw surgery. Total treatment time was 19 months. Both his occlusion and facial appearance were significantly improved by the surgical-orthodontic treatment.

The Co-Existence of NASH and Chronic Kidney Disease Boosts Cardiovascular Risk: Are there any Common Therapeutic Options?

Non-alcoholic fatty liver disease (NAFLD) is becoming the most common chronic liver disease. NAFLD may evolve to non-alcoholic steatohepatitis (NASH), which is causally related to cirrhosis and cardiovascular disease (CVD) mortality. There is no generally accepted effective treatment for NAFLD/NASH.

Intragastric Balloons in Clinical Practice.

Cost-effective therapies to address the growing epidemic of obesity are a leading priority in modern medicine. Intragastric balloons (IGBs) are one such option, with increased effectiveness compared with pharmacotherapy and lifestyle and a lower rate of adverse events than bariatric surgery. IGBs are endoscopically placed or swallowed space-occupying devices in the stomach.

Cortical specialisation to social stimuli from the first days to the second year of life: A rural Gambian cohort.

Brain and nervous system development in human infants during the first 1000days (conception to two years of age) is critical, and compromised development during this time (such as from under nutrition or poverty) can have life-long effects on physical growth and cognitive function. Cortical mapping of cognitive function during infancy is poorly understood in resource-poor settings due to the lack of transportable and low-cost neuroimaging methods. Having established a signature cortical response to social versus non-social visual and auditory stimuli in infants from 4 to 6 months of age in the UK, here we apply this functional Near Infrared Spectroscopy (fNIRS) paradigm to investigate social responses in infants from the first postnatal days to the second year of life in two contrasting environments: rural Gambian and urban UK.

Decomposition of Near-Infrared Spectroscopy Signals Using Oblique Subspace Projections: Applications in Brain Hemodynamic Monitoring.

Clinical data is comprised by a large number of synchronously collected biomedical signals that are measured at different locations. Deciphering the interrelationships of these signals can yield important information about their dependence providing some useful clinical diagnostic data. For instance, by computing the coupling between Near-Infrared Spectroscopy signals (NIRS) and systemic variables the status of the hemodynamic regulation mechanisms can be assessed.

Interactions Between Inflammatory Bowel Disease Drugs and Chemotherapy.

As new and effective novel therapies in inflammatory bowel disease (IBD) become available, patients are living longer with advancing age and are at increased risk for malignancy. The management of IBD and malignancy involves multiple combinations of chemotherapy agents and IBD drugs, with the potential for interactions between these therapies. Interactions may either potentiate the effectiveness of drug class or exacerbate their common side effects.

Using fNIRS to Study Working Memory of Infants in Rural Africa.

A pilot study was conducted to assess the feasibility of using fNIRS as an alternative to behavioral assessments of cognitive development with infants in rural Africa. We report preliminary results of a study looking at working memory in 12-16-month-olds and discuss the benefits and shortcomings for the potential future use of fNIRS to investigate the effects of nutritional insults and interventions in global health studies.

Management Guidelines for Traumatically Injured Teeth during Orthodontic Treatment.

This article presents a summary of incident management guidelines for traumatically injured teeth during orthodontic treatment. In addition, treatment of a 17-year-old patient with traumatic extrusion and palatal displacement of the permanent maxillary incisors while undergoing active orthodontic treatment is reported.

Functional near infrared spectroscopy (fNIRS) to assess cognitive function in infants in rural Africa.

Cortical mapping of cognitive function during infancy is poorly understood in low-income countries due to the lack of transportable neuroimaging methods. We have successfully piloted functional near infrared spectroscopy (fNIRS) as a neuroimaging tool in rural Gambia. Four-to-eight month old infants watched videos of Gambian adults perform social movements, while haemodynamic responses were recorded using fNIRS.

Optical imaging of brain activation in Gambian infants.

We used optical topography (OT) to investigate cognitive function in infants in rural Gambia. Images of changes in oxyhaemoglobin and deoxyhaemoglobin concentrations were reconstructed using a multispectral algorithm which uses the finite element method (FEM) to model the propagation of light through scattering tissue using the diffusion equation. High quality OT data enabled us to reconstruct images with robust representation of haemodynamic changes.

Cortical mapping of 3D optical topography in infants.

Precise localisation of cortical activation in the early development of the infant brain remains unclear. It is challenging to co-register haemodynamic responses during functional activation in infants with the underlying anatomy of the brain. We used a multispectral imaging algorithm to reconstruct 3D optical topographic images of haemodynamic responses in an infant during voice processing.

Decoupling the influence of systemic variables in the peripheral and cerebral haemodynamics during ECMO procedure by means of oblique and orthogonal subspace projections.

Extra-Corporeal Membrane Oxygenation (ECMO) is a life support system for infants and children with cardio-respiratory failure. During ECMO it is possible to have unstable cerebral haemodynamics, due to strong oscillations in the systemic variables, among other factors, which may lead to brain damage in the patients. Therefore, monitoring the coupling between cerebral haemodynamics and systemic signals might alert us of possible imminent brain damage.

Wavelet cross-correlation to investigate regional variations in cerebral oxygenation in infants supported on extracorporeal membrane oxygenation.

Extracorporeal membrane oxygenation can potentially affect cerebral blood flow dynamics and consequently influence cerebral autoregulation. We applied wavelet cross-correlation (WCC) between multichannel cerebral oxyhemoglobin concentration (HbO(2)) and mean arterial pressure (MAP), to assess regional variations in cerebral autoregulation. Six infants on veno-arterial (VA) ECMO were studied during sequential changes in the ECMO flows.

Canonical correlation analysis in the study of cerebral and peripheral haemodynamics interrelations with systemic variables in neonates supported on ECMO.

Neonates supported on extracorporeal membrane oxygenation (ECMO) are at high risk of brain injury due to haemodynamic instability. In order to monitor cerebral and peripheral (muscle) haemodynamic and oxygenation changes in this population we used a dual-channel near-infrared spectroscopy (NIRS) system. In addition, to assess interrelations between NIRS and systemic variables, collected simultaneously, canonical correlation analysis (CCA) was employed.
