AEDES JAPONICUS: A TENANT INVADER IN THE GREAT SMOKY MOUNTAINS NATIONAL PARK, USA1.

Invasive organisms may cause ecologic, economic, and public health harm. Aedes japonicus is an invasive mosquito species of known ecologic and public health importance that has widely spread throughout the eastern USA since initially being recognized in Connecticut in 1998. Here, we report the known distributions of Ae.

Ursodeoxycholic acid in the management of symptomatic gallstone disease: systematic review and clinician survey.

Background: Symptomatic gallstones are common. Ursodeoxycholic acid (UDCA) is a bile acid that dissolves gallstones. There is increasing interest in UDCA for symptomatic gallstones, particularly in those unfit for surgery.

Single-centre review of the management of intra-thoracic oesophageal perforation in a tertiary oesophageal unit: paradigm shift, short- and long-term outcomes over 15 years.

Background: Oesophageal perforation is an uncommon surgical emergency associated with high morbidity and mortality. The timing and type of intervention is crucial and there has been a major paradigm shift towards minimal invasive management over the last 15 years. Herein, we review our management of spontaneous and iatrogenic oesophageal perforations and assess the short- and long-term outcomes.

COVID-19 pandemic impacts on conservation research, management, and public engagement in US national parks.

The COVID-19 pandemic has disrupted the timing and substance of conservation research, management, and public engagement in protected areas around the world. This disruption is evident in US national parks, which play a key role in protecting natural and cultural resources and providing outdoor experiences for the public. Collectively, US national parks protect 34 million ha, host more than 300 million visits annually, and serve as one of the world's largest informal education organizations.

Building a model for day case hiatal surgery - Lessons learnt over a 10 year period in a high volume unit: A case series.

Background: Laparoscopic anti-reflux surgery has become the standard treatment for symptomatic gastro-oesophageal reflux disease refractory to medical therapy. Successful anti-reflux surgery involves safe, minimally invasive surgery, resulting in symptom resolution with minimal side effects. This study aims to assess the feasibility and safety of day case anti-reflux surgery focussing on peri- and post-operative outcomes as a measure of success.

Medium and long-term results of gastric banding: outcomes from a large private clinic in UK.

Background: Laparoscopic adjustable gastric band (LAGB) has been an established bariatric procedure for the last three decades and was, for many years, the first-choice procedure for the treatment of chronic obesity. However, more recently, the popularity of the LAGB has been in sharp decline and has been replaced by other procedures such as the Roux-En-Y gastric bypass and sleeve gastrectomy. A key driver in this decline has been the high revision and early explanation rates reported in some studies.

Changes in glycaemic control, blood pressure and lipids 5 years following laparoscopic adjustable gastric banding combined with medical care in patients with type 2 diabetes: a longitudinal analysis.

The long-term outcomes of weight loss maintenance induced by laparoscopic adjustable gastric band (LAGB) followed by multidisciplinary medical care in patients with type 2 diabetes mellitus (T2DM) (beyond 3 years) are scarcely reported. Study aims were to determine the longer term metabolic outcomes following LAGB combined with medical care in patients with T2DM. This is a longitudinal analysis of 200 adults with T2DM who had LAGB between 2003 and 2008 and were followed up till 2013 at a single bariatric unit in a tertiary UK centre.

Impact of Bariatric Surgical Intervention on Peripheral Blood Neutrophil (PBN) Function in Obesity.

Aim: The aim of this study was to investigate the impact of weight loss following gastric band surgery on multiple measures of peripheral blood neutrophil (PBN) function.

Material And Methods: Twenty-three obese patients undergoing gastric band surgery were recruited to a longitudinal intervention study, alongside non-obese, healthy gender- and age-matched controls. Eighteen pairs of patients and controls completed all stages of the study.

Influence of social deprivation on provision of bariatric surgery: 10-year comparative ecological study between two UK specialist centres.

Objective: To investigate the effect of residential location and socioeconomic deprivation on the provision of bariatric surgery.

Design: Retrospective cross-sectional ecological study.

Setting: Patients resident local to one of two specialist bariatric units, in different regions of the UK, who received obesity surgery between 2003 and 2013.

An "all 5 mm ports" technique for laparoscopic day-case anti-reflux surgery: A consecutive case series of 205 patients.

Introduction: Laparoscopic anti-reflux surgery is conventionally performed using two 10/12 mm ports. While laparoscopic procedures reduce post-operative pain, the use of larger ports invariably increases discomfort and affects cosmesis. We describe a new all 5 mm ports technique for laparoscopic anti-reflux surgery and present a review of our initial experience with this approach.

Preoperative Very Low-Calorie Diet Reduces Technical Difficulty During Laparoscopic Cholecystectomy in Obese Patients.

This study investigates the effectiveness of preoperative very low-calorie diet (VLCD) in laparoscopic cholecystectomy. A prospective observational study of consecutive patients undergoing laparoscopic cholecystectomy was undertaken. At the preoperative visit, all patients were advised to adhere to VLCD for 2 weeks before surgery (<800 kcal/d).

Day surgery for achalasia cardia: Time for consensus?

Introduction: Laparoscopic Heller's myotomy (LHM) is the most effective therapy for achalasia of the oesophagus. Most case series of LHM report a length of hospital stay (LOS) >1 day. We present 14 years of experience of LHM to examine the safety and feasibility of LHM as a day case procedure.

Trends in Ranavirus Prevalence Among Plethodontid Salamanders in the Great Smoky Mountains National Park.

Emerging pathogens are a potential contributor to global amphibian declines. Ranaviruses, which infect ectothermic vertebrates and are common in aquatic environments, have been implicated in die-offs of at least 72 amphibian species worldwide. Most studies on the subject have focused on pool-breeding amphibians, and infection trends in other amphibian species assemblages have been understudied.

A prospective cross-sectional study of laparoscopic subtotal Lind fundoplication for gastro-oesophageal reflux disease--a durable and effective anti-reflux procedure.

Introduction: Laparoscopic partial fundoplication for gastro-oesophageal reflux disease (GORD) is reported to have fewer side effects when compared to Nissen fundoplication, but doubts remain over its long term durability in controlling reflux. The aim of this study was to assess outcome of symptoms for all patients presenting with GORD undergoing routine laparoscopic subtotal Lind fundoplication.

Materials & Methods: All patients undergoing laparoscopic fundoplication between August, 1999 and November, 2007 performed by a single surgeon were included in the study.

Reinstating weight loss after leakage from gastric bands: a simple pull-through technique to replace the broken band.

Purpose: Gastric bands are mechanical devices and are susceptible to mechanical failure. Leakage from the silicone balloon represents a permanent failure of the device that inevitably leads to further surgery. We have developed a simple solution to this problem.

Safety and effectiveness of LAP-BAND AP System: results of Helping Evaluate Reduction in Obesity (HERO) prospective registry study at 1 year.

Background: Laparoscopic adjustable gastric banding has several distinctive features, including band adjustability, easy reversibility, and lack of malabsorption, which contribute to its widespread use. The LAP-BAND AP System (LBAP; Allergan, Inc.), a redesigned and improved version of the original device, was approved by the US Food and Drug Administration in 2006.

The effect of biliopancreatic diversion surgery on renal function--a retrospective study.

Background: The prevalences of obesity and chronic kidney disease (CKD) have increased simultaneously. Should a pathophysiological relationship exist between the two conditions, bariatric surgery and associated weight loss could be an important intervention in extremely obese individuals to slow the progression of CKD.

Methods: We conducted a retrospective analysis of 25 patients who had undergone biliopancreatic diversion (BPD) surgery for extreme obesity (body mass index >40 kg/m(2)), with mean follow-up of 4 years.

Medium-term outcomes of patients with insulin-dependent diabetes after laparoscopic adjustable gastric banding.

Background: Bariatric surgery is effective in the control of type 2 diabetes mellitus. Laparoscopic adjustable gastric banding is a popular form of bariatric surgery, but very limited data are available on its long-term effect on type 2 diabetes mellitus. The present study examined the effect of gastric banding on a consecutive cohort of unselected patients with insulin-dependent diabetes mellitus at a teaching hospital in Birmingham, United Kingdom.

Band slippage and erosion after laparoscopic gastric banding: a meta-analysis.

Background: Laparoscopic adjustable gastric banding has the lowest morbidity and mortality rates among the common bariatric procedures. Troublesome complications associated with this procedure include band slippage and erosion, often requiring revisionary surgery. Rates of slippage have decreased, and this appears to be due to changes in surgical technique.

Dietetic-led management of patients undergoing laparoscopic gastric banding: early results.

Background: Optimal results of bariatric surgery are achieved when it is performed within a multidisciplinary team. Within this team, the dietician plays a key role before and after surgery in patient education and behaviour change. With long-term follow-up, the number of patients per surgeon increases exponentially.

Prospective study of routine day-case laparoscopic modified Lind partial fundoplication.

Background: The aim of the present study was to prospectively assess the feasibility, safety, and acceptability of performing day-case laparoscopic modified Lind fundoplication for gastroesophageal reflux disease on a routine basis and to determine possible implications for health care costs to the hospital.

Methods: All patients undergoing laparoscopic fundoplication between November 2005 and November 2007 under the care of one surgeon were included in the study. Inclusion criteria were American Society of Anesthesiologists (ASA) grade I and II with adequate home support.

Laparoscopic Heller myotomy for achalasia: changing trend toward "true" day-case procedure.

Background: Laparoscopic Heller myotomy is the most effective therapy for achalasia. All case series have reported a minimum length of stay of more than 1 day. "True" day-case laparoscopic Heller myotomy has not been reported, so far.

Age > or =50 does not influence outcome in laparoscopic gastric banding.

Background: Laparoscopic adjustable gastric banding is an accepted treatment for obesity. Age greater than 50 carries a theoretically increased risk from weight loss surgery and perhaps less clinical benefit in the long term. We compare results of gastric banding at age 50 and above with age below 50 in our unit.
