Abstract
Opiates can cause heartburn and spastic esophageal dysmotility but their role in noncardiac chest pain (NCCP) is not known. Our aim was to characterize opiate effects on esophageal function using esophageal pH monitoring and high-resolution manometry (HREM) in these patients.We performed a cross sectional study of opiate users with NCCP who underwent HREM and esophageal pH study from 2010 to 2017 using opiate nonusers as a comparison group. Demographic data, symptoms, opiate use, endoscopic findings, esophageal pH study parameters, and HREM data were abstracted.Thirty three patients with NCCP on opiates were compared to 144 opiate non-users. Compared to opiate nonusers, opiate users had lower total acid exposure (2.3% vs. 3%, P = 0.012), lower upright acid exposure (1.2% vs. 3.1%, P = 0.032) and lower DeMeester score (6.5 vs. 12.7, P = 0.016). Opiate users also had higher lower esophageal sphincter integrated relaxation pressure (LES-IRP) (7.0 mm Hg [2.2, 11.7] vs. 3.7 mm Hg [1.1, 6.2] P = 0.011) and greater mean distal contractile integral (DCI) (2575 mm.Hg.s.cm [1134, 4466] vs. 1409 mm.Hg.s.cm [796, 3003] P = 0.03) than opiate non-users. The prevalence of hypertensive motility disorders (15.2% vs. 11.1%) and achalasia (12.1% vs. 2.1%) was higher in opiate users (P = 0.039) but did not reach significance on multivariate analysis.In patients presenting with NCCP, opiate users had lower esophageal acid exposure compared to opiate nonusers. This might be due to higher LES pressures preventing reflux and higher DCI leading to more rapid acid esophageal clearance.

Abstract
Here we assess the quality and in-season development of European wheat (Triticum spp.) yield forecasts during low, medium, and high-yielding years. 440 forecasts were evaluated for 75 wheat forecast years from 1993-2013 for 25 European Union (EU) Member States. By July, years with median yields were accurately forecast with errors below ~2%. Yield forecasts in years with low yields were overestimated by ~10%, while yield forecasts in high-yielding years were underestimated by ~8%. Four-fifths of the lowest yields had a drought or hot driver, a third a wet driver, while a quarter had both. Forecast accuracy of high-yielding years improved gradually during the season, and drought-driven yield reductions were anticipated with lead times of ~2 months. Single, contrasting successive in-season, as well as spatially distant dry and wet extreme synoptic weather systems affected multiple-countries in 2003, '06, '07, '11 and 12', leading to wheat losses up to 8.1 Mt (>40% of total EU loss). In these years, June forecasts (~ 1-month lead-time) underestimated these impacts by 10.4 to 78.4%. To cope with increasingly unprecedented impacts, near-real-time information fusion needs to underpin operational crop yield forecasting to benefit from improved crop modelling, more detailed and frequent earth observations, and faster computation.

Abstract
Obstructive sleep apnea syndrome is a common problem among children and is recognized as a cause of significant medical morbidity. Since the 1980s, it has been suggested that obstructive sleep apnea syndrome is a risk factor for growth failure in children. In many cases, it has been shown that growth failure is reversible once the obstructive sleep apnea syndrome is resolved. The objectives of this study were to analyze and compare growth failure prevalence in a Mediterranean population of children with obstructive sleep apnea syndrome and healthy children matched in age and sex, and to assess the effectiveness of tonsillectomy and adenoidectomy in resolving growth retardation. We compared 172 children with obstructive sleep apnea syndrome (apnea-hypopnea index ≥ 3) who had undergone tonsillectomy and adenoidectomy with 172 healthy controls in terms of key anthropometric parameters. Most of the criteria used for growth failure were higher to a statistically significant degree in the study group vs the control group: height-for-age ≤ 3rd percentile (7.56% vs 2.91%; p = 0.044), weight-for-age ≤ 5th percentile (9.30% vs 2.33%; p = 0.005), weight-for-age ≤ 3rd percentile (8.14% vs 2.33%; p = 0.013) and height and/or weight for-age ≤ 5th percentile (13.95% vs 5.81%; p = 0.009). The height-for-age ≤ 5th percentile was almost at the limit of statistical significance (8.72% for the study group vs 4.65% for the control group; p = 0.097). At one-year post-surgery follow-up, 10 of 15 children with height-for-age ≤ 5th percentile had achieved catch-up growth (66.6%), and 14 of 24 children with height- and/or weight-for-age ≤ 5th percentile had normalized growth (58.33%). For children with failure to thrive or who have growth failure, physicians should consider the possibility of obstructive sleep apnea. A significant number of children with obstructive sleep apnea concurrent with growth failure could benefit from tonsillectomy and adenoidectomy to recover and normalize their growth rate.

Abstract
PURPOSE To study an original 3D visualization of head and neck squamous cell carcinoma extending to the mandible by using [18F]-NaF PET/CT and [18F]-FDG PET/CT imaging along with a new innovative FDG and NaF image analysis using dedicated software. The main interest of the 3D evaluation is to have a better visualization of bone extension in such cancers and that could also avoid unsatisfying surgical treatment later on. PATIENTS AND METHODS A prospective study was carried out from November 2016 to September 2017. Twenty patients with head and neck squamous cell carcinoma extending to the mandible (stage 4 in the UICC classification) underwent [18F]-NaF and [18F]-FDG PET/CT. We compared the delineation of 3D quantification obtained with [18F]-NaF and [18F]-FDG PET/CT. In order to carry out this comparison, a method of visualisation and quantification of PET images was developed. This new approach was based on a process of quantification of radioactive activity within the mandibular bone that objectively defined the significant limits of this activity on PET images and on a 3D visualization. Furthermore, the spatial limits obtained by analysis of the PET/CT 3D images were compared to those obtained by histopathological examination of mandibular resection which confirmed intraosseous extension to the mandible. RESULTS The [18F]-NaF PET/CT imaging confirmed the mandibular extension in 85% of cases and was not shown in [18F]-FDG PET/CT imaging. The [18F]-NaF PET/CT was significantly more accurate than [18F]-FDG PET/CT in 3D assessment of intraosseous extension of head and neck squamous cell carcinoma. This new 3D information shows the importance in the imaging approach of cancers. All cases of mandibular extension suspected on [18F]-NaF PET/CT imaging were confirmed based on histopathological results as a reference. CONCLUSIONS The [18F]-NaF PET/CT 3D visualization should be included in the pre-treatment workups of head and neck cancers. With the use of a dedicated software which enables objective delineation of radioactive activity within the bone, it gives a very encouraging results. The [18F]-FDG PET/CT appears insufficient to confirm mandibular extension. This new 3D simulation management is expected to avoid under treatment of patients with intraosseous mandibular extension of head and neck cancers. However, there is also a need for a further study that will compare the interest of PET/CT and PET/MRI in this indication.

Abstract
The classic manometric findings in systemic sclerosis are aperistalsis of the esophageal body with hypotensive lower esophageal sphincter. These changes contribute to gastroesophageal reflux disease in these patients. With widespread use of high-resolution esophageal manometry, diverse abnormalities are seen. The aim of this study is to characterize esophageal dysmotility in patients with systemic sclerosis undergoing high-resolution esophageal manometry and compare demographic features and diagnostic test results among patients with varying degrees of esophageal dysmotility. Patients with systemic sclerosis who underwent high-resolution esophageal manometry between January 2008 and October 2014 at our institution were identified. High-resolution esophageal manometry studies were reinterpreted using the Chicago Classification, v3.0 criteria. We also reviewed the patient charts for demographic data, indications for manometry, esophagogastroduodenoscopy findings, pH studies, medication use, and autoantibody panel. The cohort consisted of 122 patients with a mean age of 53.3 ± 15.3 years. High-resolution esophageal manometry was normal in 23, showed ineffective esophageal motility in 22, absent contractility in 73, and one case each of type II achalasia, esophagogastric junction outflow obstruction, hypercontractile esophagus, and distal esophageal spasm. Patients with absent contractility were younger and more likely to have erosive esophagitis, hiatal hernia, and esophageal strictures than patients with ineffective esophageal motility or normal manometry. There were no statistically significant differences in the groups based on autoantibodies or indications for manometry. Diverse esophageal motility abnormalities were noted in systemic sclerosis with ineffective esophageal motility or absent contractility observed in over three-fourth of the patients. Patients with absent contractility were younger and had more severe reflux. The severity of gastroesophageal reflux disease related endoscopic findings correlated with the degree of esophageal dysmotility on high-resolution esophageal manometry.

Abstract
BACKGROUND This study evaluated whether demographics, pre-diagnosis lifestyle habits and clinical data are associated with the overall survival (OS) and head and neck cancer (HNC)-specific survival in patients with HNC. PATIENTS AND METHODS We conducted a pooled analysis, including 4759 HNC patients from five studies within the International Head and Neck Cancer Epidemiology (INHANCE) Consortium. Cox proportional hazard ratios (HRs) and the corresponding 95% confidence intervals (CIs) were estimated including terms reported significantly associated with the survival in the univariate analysis. RESULTS Five-year OS was 51.4% for all HNC sites combined: 50.3% for oral cavity, 41.1% for oropharynx, 35.0% for hypopharynx and 63.9% for larynx. When we considered HNC-specific survival, 5-year survival rates were 57.4% for all HNC combined: 54.6% for oral cavity, 45.4% for oropharynx, 37.1% for hypopharynx and 72.3% for larynx. Older ages at diagnosis and advanced tumour staging were unfavourable predictors of OS and HNC-specific survival. In laryngeal cancer, low educational level was an unfavourable prognostic factor for OS (HR = 2.54, 95% CI 1.01-6.38, for high school or lower versus college graduate), and status and intensity of alcohol drinking were prognostic factors both of the OS (current drinkers HR = 1.73, 95% CI 1.16-2.58) and HNC-specific survival (current drinkers HR = 2.11, 95% CI 1.22-3.66). In oropharyngeal cancer, smoking status was an independent prognostic factors for OS. Smoking intensity (>20 cigarettes/day HR = 1.41, 95% CI 1.03-1.92) was also an independent prognostic factor for OS in patients with cancer of the oral cavity. CONCLUSIONS OS and HNC-specific survival differ among HNC sites. Pre-diagnosis cigarette smoking is a prognostic factor of the OS for patients with cancer of the oral cavity and oropharynx, whereas pre-diagnosis alcohol drinking is a prognostic factor of OS and HNC-specific survival for patients with cancer of the larynx. Low educational level is an unfavourable prognostic factor for OS in laryngeal cancer patients.

Abstract
BACKGROUND Gastrointestinal (GI) dysmotility is common in diabetic patients. Wireless Motility Capsule (WMC) provides the transit profile of the entire GI tract in a single study. Factors affecting GI dysmotility and utility of WMC study are not clearly established in diabetic patients. Our aims were to study the pattern of GI dysmotility using WMC and evaluate the effect of glycemic control and presence of diabetic microvascular complications on motility impairment in diabetic patients. We also assessed the impact of WMC findings on clinical management. METHODS Retrospective chart review of all diabetic patients who underwent WMC testing at our institution from 2010 to 2015 was performed. Demographics, hemoglobinA1c levels, microvascular complications, and WMC findings were obtained. Impact of WMC on clinical management was assessed. KEY RESULTS A total of 100 patients were included. Mean age was 45±19 years and 76% were female. Seventy-two percentage had abnormal WMC testing, of which 29 (40%) had multiregional dysmotility. There were no significant differences in demographics, diabetic microvascular complications or hemoglobinA1c levels among patients with normal and abnormal WMC testing or among patients with isolated vs multiregional dysmotility. Information about subsequent clinical management was available for 47 patients. WMC testing was abnormal in 33 (70%) patients and treatment changes based on WMC results were made in 24 patients (73%). CONCLUSIONS & INFERENCES There was no association between hemoglobinA1c levels, microvascular complications and pattern of GI dysmotility in diabetic patients undergoing WMC. WMC testing lead to management changes in approximately 75% of diabetic patients with GI dysmotility.

Abstract
BACKGROUND Chronic hepatitis B virus (HBV) infection has a mild course in most children that may delay initiation of treatment even when indicated. Unfortunately, a small number of cases can progress rapidly to cirrhosis, which may require liver transplantation (LT) in early adulthood. The aim of this study was to assess the characteristics of HBV-positive young adults who received LT and to evaluate post-transplant outcomes including patient and graft survival and differences between pre- and post-implementation of Model for End-stage Liver Disease (MELD) prioritization. METHODS The United Network for Organ Sharing (UNOS) database review was conducted from 1987 to 2012, and a retrospective analysis was performed on all young adult patients (ages 18-35 years) who underwent LT in the United States with a primary diagnosis of HBV or were seropositive for HBV surface antigen at time of LT. Kaplan-Meier analysis was used to assess patient and graft survival in the pre-MELD and post-MELD eras. Factors associated with survival were identified through the use of Cox regression analysis. RESULTS A total of 522 HBV-infected subjects were included. Average age at time of transplant was 28.4 ± 5.2 years; 60.9% were male, 48.6% were white, the mean body mass index was 25 ± 5.5 kg/m2, diabetes was present in 3.9%, hepatocellular carcinoma (HCC) was present in 4.4%, and 10.4% were on dialysis prior to LT. Median follow-up after first LT was 48.2 months [12.5, 109]. During this time, 174 (33.3%) patients died with a mean age at the time of death of 31.6 ± 7.8 years, including 144 of 522 (28%) after the first LT, 26 of 74 (35%) after the second LT, and 4 of 12 (33%) after the third LT. The most common cause of death was graft failure (27.6%), followed by infection (16.6%). Overall, only 58% of patients were alive with their first LT at last follow-up. Kaplan-Meier analysis revealed worse patient and graft survival after re-transplantation in comparison to initial LT. Three hundred thirty subjects were transplanted in the pre-MELD era and 192 were transplanted in post-MELD era. Obesity, HCC, shorter ventilation use, shorter cold ischemia time, and non-white donor race were significantly more common in the post-MELD era (all with P < .05). Importantly, 5-year patient and graft survival rates were higher in the post-MELD era compared with the pre-MELD era. CONCLUSIONS LT in young adults for HBV has poor outcomes and can be associated with premature death. These findings should prompt more aggressive evaluation and treatment for HBV in young patients. Superior outcomes in the post-MELD era compared with the pre-MELD era may be attributed to pre-transplant factors, improved surgical technique, and better treatment options for HBV infection.

Abstract
Background In the PrefHer study, subcutaneous administration of trastuzumab was preferred over intravenous administration (iv). In 2014 our hospital approved subcutaneous (sc) trastuzumab for use in patients with early or metastatic Her 2 positive breast cancer. The aim of this study was to evaluate patients (pts) and nurses´s preferences in our institution.
Methods Patients with Her2 postive breast cancer and nurses who had received or administered both sc and iv trastuzumab were interviewed to evaluate their preference. Preference for sc was compared with a linear chi squared test.
Results 55 pts were interviewed. Median age was 53 years (30-83). 30 patients in adjuvant/neoad setting and 25 pts in the palliative setting. 41 pts (74.5%) preferred sc 95% CI (63-86) , 3 pts (5.5%) preferred iv 95% CI (-0.5-11.5) and 11 pts (20%) did not have preference 95% CI (9.4-20%) p< 0.0001. 72% of pts considered that sc trastuzumab was more convenient (p<0.0001). 11 nurses experienced with both iv and sc trastuzumab administration answered the questionnaire. Median age 41 years (30-55). 10/11 nurses preferred sc administration, 1/10 indicated no preference. All nurses considered that sc was the most convenient administration method for the patients and is highly recommended. The main reason for patients and nurses preference was that sc administration saved time.
Conclusion Patients and nurses prefer s.c over iv trastuzumab. Our results are consistent with PrefHer study. Incorporation of sc trastuzumab could improve quality of care in patients with Breast Cancer Her 2 positive.

Abstract
The aim of this study was to measure the efficacy of a positional therapy device (PTD) at reducing proton pump inhibitor (PPI) refractory nocturnal GERD symptoms. Among patients with GERD, nocturnal symptoms are very common. A recent study demonstrated a decrease in nocturnal acid exposure and reflux episodes in healthy volunteers who slept using a PTD. This is a single-center prospective trial involving patients on anti-secretory medications with continued nocturnal heartburn and regurgitation. Patients completed the Nocturnal GERD Symptom Severity and Impact Questionnaire (N-GSSIQ) and GERD health-related quality of life questionnaire (GERD-HRQL) at enrollment. Patients were instructed to sleep on the PTD for at least 6 hours a night during the two week study period; subjects continued their baseline anti-secretory medication dose. After 2 weeks, the questionnaires were repeated. A total of 27 patients (16 females and 11 males; age 57.8 ± 15.1) were recruited. After 2 weeks of PTD use, N-GSSIQ scores significantly improved from baseline, with a mean total score improvement of 39.5 (mean 57.7 [pre] vs. 18.2 [post], P < 0.001). Significant improvement from baseline was also observed for the GERD-HRQL questionnaire (29.8 vs. 16.7, P < 0.001). No adverse events were reported. At 3 months after the trial period, 91% of the subjects continued to use the PTD on a nightly basis. Use of the PTD significantly decreased nocturnal GERD symptoms and improved GERD-HRQL. The PTD was well tolerated during the study period and for 3 months after enrollment.

Int J Obes (Lond) 2016; 41:443-449. [PMID: 27881858 DOI: 10.1038/ijo.2016.212] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/22/2016] [Revised: 11/07/2016] [Accepted: 11/13/2016] [Indexed: 02/06/2023]
Abstract
BACKGROUND Bariatric surgery is performed safely in non-alcoholic fatty liver disease (NAFLD) patients with minimal fibrosis (stage 1-2). However, the safety and potential benefits of bariatric surgery for NAFLD with advanced fibrosis (stage 3-4) remain unclear. This study was designed to compare the safety and efficacy of bariatric surgery in patients with biopsy proven advanced fibrosis to those with minimal fibrosis. METHODS All patients who underwent bariatric surgery between 2005 and 2014 and had evidence of NAFLD with fibrosis score 3-4 (advanced fibrosis) based on the staging system defined by Kleiner et al. on intraoperative liver biopsy were included and compared with patients who had fibrosis score 1-2 (minimal fibrosis). The groups were compared for length of hospital stay after bariatric surgery and incidence of postoperative complications over a follow-up period of 1 year. An improvement in hepatic function tests before and 1 year after surgery was used as a parameter to evaluate for NAFLD improvement. RESULTS Ninety-nine patients with F3-4 (group 1) and 198 patients with F1-2 (group 2) were included. Mean age (51.9 vs 50.1 years) and body mass index (46.4 vs 46.5 kg m-2) were similar in the two groups. Median serum aspartate aminotransferase (43 vs 30 U l-1; normal 10-40 U l-1) and alanine aminotransferase (40.5 vs 34 U l-1; normal 10-50 U l-1) were significantly higher in group 1 and improved 1 year after surgery. Median length of hospital stay after surgery was higher in group 1 than that in group 2 (4 days vs 3 days; P-value=0.002). The proportion of patients developing postoperative complications over 1 year was similar in both groups (36.4% vs 32.8%; P-value=0.54). CONCLUSIONS Advanced fibrosis does not increase the risk of developing postoperative complications in medically optimized patients undergoing bariatric surgery. Improvement in serum transaminase levels suggests a reduction in hepatic necroinflammatory activity following bariatric surgery.
