BACKGROUND: Repetitive, retrograde contractions (RRCs) in response to sustained esophageal distension are a distinct contractility pattern observed with functional luminal imaging probe (FLIP) panometry that are common in type III (spastic) achalasia. RRCs are hypothesized to be indicative of either impaired inhibitory innervation or esophageal outflow obstruction. We aimed to apply FLIP panometry to patients with post-fundoplication dysphagia (a model of esophageal obstruction) to explore mechanisms behind RRCs...

INTRODUCTION: Obesity is related with higher incidence of gastroesophageal reflux disease. Antireflux surgery has inadequate results when associated with obesity, due to migration and/or subsequent disruption of antireflux wrap. Gastric bypass, meanwhile, provides good control of gastroesophageal reflux. OBJECTIVE: To evaluate the technical difficulty in performing gastric bypass in patients previously submitted to antireflux surgery, and its effectiveness in controlling gastroesophageal reflux...

BACKGROUND: Laparoscopic manual suturing is probably the most difficult skill to be acquired in minimally invasive surgery. However, laparoscopic exercise endo-sutures can be learned with a simulator and are of great practical importance and clinical applicability, absorbing concepts that are immediately transferred to the operating room. AIM: To assess the progression of skills competence in endo-sutures through realistic simulation model of systematized education...

BACKGROUND: Obese patients with gastroesophageal reflux disease with pathological pH monitoring result may benefit from surgical treatment which is based on the fundoplication technique in association with laparoscopic gastric plication. The Nissen surgery is the gold standard for surgical treatment of gastroesophageal reflux disease, whereas laparoscopic gastric plication is a restrictive surgery that consists of the invagination of the greater curvature, resulting in weight loss. AIM: To compare pre and postoperative pHmetry results and to evaluate weight loss in patients submitted to gastroplasty with fundoplication...

Background: Exercise tolerance decreases as COPD progresses. Pulmonary hypertension (PH) is common in COPD and may reduce performance further. COPD patients with and without PH could potentially be identified by cardiopulmonary exercise test (CPET). However, results from previous studies are diverging, and a unified conclusion is missing. We hypothesized that CPET combined with arterial blood gases is useful to discriminate between COPD outpatients with and without PH. Methods: In total, 93 COPD patients were prospectively included...

BACKGROUND: The method of graft fixation in primary anterior cruciate ligament (ACL) reconstruction is important for initial stability of the graft. Poor graft fixation can result in failure of the reconstruction. The effect of ACL graft fixation principles and fixation implant combinations on the risk of revision after ACL reconstruction is not well understood. PURPOSE: The study aimed to compare the risk of revision among 4 categories of femoral fixation divided by their principle of function using a hamstring tendon (HT) graft only...

OBJECTIVE: Several studies have suggested that patients with rheumatoid arthritis (RA) presenting with ultrasound (US) synovitis despite clinical remission have more subsequent flares than those who show both clinical and sonographic remission. The objective of our study was to investigate whether these results could be translated to a real-life setting. METHODS: We compared the time from the first US performed in clinical remission to loss of remission (defined by a DAS28 > 2...

Background: The 50-year old Aedes albopictus C6/36 cell line is a resource for the detection, amplification, and analysis of mosquito-borne viruses including Zika, dengue, and chikungunya. The cell line is derived from an unknown number of larvae from an unspecified strain of Aedes albopictus mosquitoes. Toward improved utility of the cell line for research in virus transmission, we present an annotated assembly of the C6/36 genome. Results: The C6/36 genome assembly has the largest contig N50 (3...

OBJECTIVE: To identify nurses' experiences of administering oral medications to residents of aged care facilities (ACFs) with swallowing difficulties. INTRODUCTION: Administering medicines to older people with swallowing difficulties is a challenging task. Nurses frequently modify oral medications e.g. by crushing/splitting tablets or opening capsules, to facilitate the administration process. These practices are associated with an increased risk of medication administration errors...

We herein report a case of one-stage laparoscopic surgery for extralobar pulmonary sequestration (EPS) and hiatal hernia. Our patient was a 2-year-old girl who was diagnosed as a mediastinal mass lesion. Postnatal computed tomography revealed that the mediastinal mass was an EPS. Two weeks after birth, the patient developed gastroesophageal reflux (GER), and esophagography showed a hiatal hernia. At 2 years of age, she underwent one-stage laparoscopic Nissen's fundoplication for GER with resection of the EPS in the posterior mediastinum...

Monocytosis is considered a poor prognostic factor for many cancers, including B cell lymphomas. The mechanisms by which different monocyte subsets support the growth of lymphoma is poorly understood. Using a pre-clinical mouse model of B cell non-Hodgkin's lymphoma (B-NHL), we investigated the impact of tumor progression on circulating monocyte levels, subset distribution and their activity, with a focus on immune suppression. B-NHL development corresponded with significant expansion initially of classical (Ly6Chi) and non-classical (Ly6Clo) monocytes, with accumulation and eventual predominance of Ly6Clo cells...

BACKGROUND & AIMS: The effects of transoral incisionless fundoplication (TIF) and laparoscopic Nissen fundoplication (LNF) have been compared with those of proton pump inhibitors (PPIs) or a sham procedure in patients with gastroesophageal reflux disease (GERD), but there has been no direct comparison of TIF vs LNF. We performed a systematic review and network meta-analysis of randomized controlled trials to compare the relative efficacies of TIF vs LNF in patients with GERD. METHODS: We searched publication databases and conference abstracts through May 10, 2017 for randomized controlled trials that compared the efficacy of TIF or LNF with that of a sham procedure or PPIs in patients with GERD...

OBJECTIVE: To evaluate late outcomes from a randomized trial of division versus no division of short gastric vessels during laparoscopic Nissen fundoplication at up to 20 years follow-up. BACKGROUND: Nissen fundoplication is an established procedure for the treatment of gastroesophageal reflux disease. Controversy about whether side effects such as dysphagia could be reduced by division of the short gastric vessels led to the establishment of a randomized trial in 1994...

We use a one-electron quantum dot as a spectroscopic probe to study the spin properties of a gate-controlled multielectron GaAs quantum dot at the transition between odd and even occupation numbers. We observe that the multielectron ground-state transitions from spin-1/2-like to singletlike to tripletlike as we increase the detuning towards the next higher charge state. The sign reversal in the inferred exchange energy persists at zero magnetic field, and the exchange strength is tunable by gate voltages and in-plane magnetic fields...

Statins therapy reduces atheroma in proportion to the reduction of low-density lipoprotein cholesterol (LDL-C). Proprotein convertase subtilisin--kexin type 9 (PCSK9) inhibitors are a new class of injectable human monoclonal antibodies shown to lower LDL-C when added to statin therapy. In a randomized, double-blind, placebo-controlled study, 968 patients with symptomatic coronary artery disease were treated with statins alone or combined with the PCSK9 inhibitor, evolocumab, and assessed for change in percent, total volume, and regression of coronary atheroma...

Jason Ralph, Jess Gifkins
Practice theory provides important insights into the workings of the Security Council. The contribution is currently limited, however, by the conjecture that practice theory operates on 'a different analytical plane' to norm/normative theory. Building on existing critiques, we argue that analysing practices separately from normative positions risks misappropriating competence and reifying practice that is not fit for purpose. This risk is realized in Adler-Nissen and Pouliot's practice-based account of the Libya crisis...

INTRODUCTION: Viral acute respiratory infections (ARIs) cause substantial child morbidity. Sensitive molecular-based assays aid virus detection, but the clinical significance of positive tests remains uncertain as some viruses may be found in both acutely ill and healthy children. We describe disease-pathogen associations of respiratory viruses and quantify virus-specific attributable risk of ARIs in healthy children during the first 2 years of life. METHODS: One hundred fifty-eight term newborn babies in Brisbane, Australia, were recruited progressively into a longitudinal, community-based, birth cohort study conducted between September 2010 and October 2014...

BACKGROUND: Articular cartilage health is an important issue following anterior cruciate ligament (ACL) injury and primary ACL reconstruction. Factors present at the time of primary ACL reconstruction may influence the subsequent progression of articular cartilage damage. HYPOTHESIS: Larger meniscus resection at primary ACL reconstruction, increased patient age, and increased body mass index (BMI) are associated with increased odds of worsened articular cartilage damage at the time of revision ACL reconstruction...
