BACKGROUND: Gastroesophageal reflux disease (GERD) and esophageal dysmotility are often disqualifying criteria for fundoplication due to dysphagia complications. A tailored partial fundoplication may improve GERD in patients with severe esophageal motility disorders. We evaluate this approach on GERD improvement in non-achalasia esophageal dysmotility patients. METHODS: A single-institution prospective database was reviewed (2007-2016), with inclusion criteria of GERD, previous diagnosis of non-achalasia esophageal motility disorder, and laparoscopic partial fundoplication...

BACKGROUND: There is insufficient prospective data on quality of life outcomes for laryngeal cancer patients undergoing surgery, especially in low- and middle-income countries. This limits clinical and patient decision-making, and survivorship expectations. This research aimed to define longitudinal changes in quality of life in patients with laryngeal cancer from the pre-operative to post-operative period. MATERIALS AND METHODS: A prospective cohort with primary laryngeal cancer treated with standard-of-care surgery who have completed a minimum follow-up of 1 year were evaluated...

Laparoscopic esophageal myotomy is the standard surgical intervention for achalasia. Compared to standard laparoscopic techniques, use of the robot has theoretical advantages of improved visualization and dexterity. We evaluated the University of Arizona's experience with the two alternatives to compare outcomes. Patients who underwent either laparoscopic or robot-assisted myotomy were identified from a retrospective database from 1/1/2006 to 12/31/2015. Patient demographics, prior treatment, intra-operative complications, operative time, post-operative length of stay and complications, and long-term results were compared between the two groups...

The experimental pathophysiology of organophosphorus (OP) chemical exposure has been extensively reported. Here, we describe an altered fecal bacterial biota and urine metabolome that follows intoxication with soman, a lipophilic G class chemical warfare nerve agent. Non-anaesthetized Sprague-Dawley male rats were subcutaneously administered soman at 0.8 (sub-seizurogenic) or 1.0 (seizurogenic) of the median lethal dose (LD50 ) and evaluated for signs of toxicity. Animals were stratified based on seizing activity to evaluate effects of soman exposure on fecal bacterial biota and urine metabolites...

BACKGROUND: Perioperative major adverse cardiovascular and cerebrovascular events (MACCEs) are incompletely understood, and risk prediction is imprecise. Atherogenic leukocytes are crucial in cardiovascular events. However, it is unclear if surgical interventions affect leukocyte counts or activation status. Therefore, we investigated whether noncardiac surgery in patients with elevated cardiovascular risk is associated with changes in atherogenic leukocyte subsets and if these changes are related to perioperative MACCEs...

Background: Poor results after repair of type 2 SLAP tears are relatively common and some have reported better results after biceps tenodesis or tenotomy than repair. In addition, some believe that the long head of the biceps is expendable. Therefore, many now favor biceps tenotomy or tenodesis over biceps anchor repair either in all patients or in older patients, reserving SLAP lesion repair only for young athletes. Hypothesis: We hypothesized that repair of the biceps anchor of the labrum would be effective in all patients regardless of age provided that care was taken not to overtighten the labrum and that rotator cuff pain as the primary pain generator had been ruled out...

PURPOSE: Prior to 90 Y radioembolization, a pretreatment procedure is performed, in which 99m Tc-macroaggerated albumin (99m Tc-MAA) is administered to estimate the amount of activity shunting to the lungs. A high lung shunt fraction (LSF) may impose lower prescribed treatment activity or even impede treatment. Accurate LSF measurement is therefore important, but is hampered by the use of MAA particles, which differ from 90 Y microspheres. Ideally, 90 Y microspheres would also be used for the pretreatment procedure, but this would require the activity to be lower than an estimated safety threshold of about 100 MBq to avoid unintended radiation damage...

The aim of this study was to evaluate the bone regeneration capacity of a Pluronic® F127 (P)-Tetronic®1307 (T) and α-cyclodextrin (CD) supramolecular gel (P-T-CD) in a 11/7/7 ratio containing BMP-2 and 17β-estradiol pre-encapsulated in poly-lactide-co-glycolide (PLGA) and poly-lactic acid (PLA-S) microspheres, respectively. Ovariectomy combined with dexamethasone treatment was used to induce an osteoporotic (OP) animal model of calvaria critical size defect in female rats to test the system. The two active substances showed a biphasic in vitro release profile characterized by an initial fast phase followed by a slow and prolonged release...

Lingual branches of the glossopharyngeal nerve (CN Ⅸ) are at risk of injury during tonsillectomy due to their proximity to the muscle layer of the palatine tonsillar bed. However, it is unclear how often this common surgery leads to taste disturbances. We conducted a literature search using PubMed, Embase, Cochrane Library, Google Scholar, PsychInfo, and Ovid Medline to evaluate the available literature on post-tonsillectomy taste disorders. Studies denoting self-reported dysfunction, as well as those employing quantitative testing, i...

Different fields of cancer management consider bone health to be of increasing clinical importance for patients: 1) presence of bone metastases in many solid tumors, 2) use of bone-targeted treatments in the reduction of bone metastasis, 3) effects of cancer treatment on reproductive hormones, critical for normal bone remodeling maintenance. Additionally, bone microenvironment is further complicated by the decline of ovarian sex steroid production and by the related increase in inflammatory factors linked to menopause, which result in accelerated bone loss and increased risk of osteoporosis (OP)...

OBJECTIVE: Hydrocephalus is a medical condition in which there is an abnormal accumulation of cerebrospinal fluid (CSF) in the brain. Segmentation of brain imagery into brain tissue and CSF [before and after surgery, i.e., preoperative (pre-op) versus postoperative (post-op)] plays a crucial role in evaluating surgical treatment. Segmentation of pre-op images is often a relatively straightforward problem and has been well researched. However, segmenting post-op computational tomographic (CT) scans becomes more challenging due to distorted anatomy and subdural hematoma collections pressing on the brain...
