#1
Michael Chae, Lin Xia, Chengyong Zhu, David C Bressler
Although the improved dewaterability and digestibility of primary biosolids subjected to thermal hydrolysis has been studied for decades, there are a surprisingly small number of studies exploring the use of this thermal treatment for digested biosolids that are typically left to settle in large settling lagoons. This is likely because of the high capital and operating costs associated with thermal hydrolysis, coupled with the limited applications and value of the resulting products. However, due to the anticipated increases in the amount of generated biosolids combined with issues surrounding potential environmental release and the limited availability of land for additional lagoons, other biosolids management strategies are being explored...

The survival of aquatic biota in stream ecosystems depends on both water quantity and quality, and is particularly susceptible to degraded water quality in regulated rivers. Maintenance of environmental flows (e-flows) for aquatic biota with optimum water quantity and quality is essential for sustainable ecosystem services, especially in developing regions with insufficient stream monitoring of hydrology, water quality and aquatic biota. Few e-flow methods are available that closely link aquatic biota tolerances to pollutant concentrations in a simple and practical manner...

BACKGROUND: The risk of invasive cancer in resected intraductal papillary mucinous neoplasm with main pancreatic duct involvement is 33%-60%. Most guidelines, therefore, advise resection of main duct intraductal papillary mucinous neoplasm and mixed type intraductal papillary mucinous neoplasm in surgically fit patients, although advice on the surgical strategy (partial or total pancreatectomy) differs. We performed a survey amongst international experts to guide the design of future studies and help to prepare for a single international set of guidelines...

Understanding the temporal dynamics of multi-species biofilms in Drinking Water Distribution Systems (DWDS) is essential to ensure safe, high quality water reaches consumers after it passes through these high surface area reactors. This research studied the succession characteristics of fungal and bacterial communities under controlled environmental conditions fully representative of operational DWDS. Microbial communities were observed to increase in complexity after one month of biofilm development but they did not reach stability after three months...

INTRODUCTION: Tracheal adenoid cystic carcinoma (ACC) is rare and accounts for <1% of all lung cancers. Although ACC is classified as a low-grade tumor, metastases are frequently identified in the late period. Extrapulmonary metastases are rare, and their resection has rarely been reported. PRESENTATION OF CASE: Case 1: A 77-year-old man underwent tracheal resection for ACC with postoperative radiation (60 Gy) 14 years before (at the age of 63). He underwent two subsequent pulmonary resections for metastases...

High levels of pain, significant anxiety, and/or depressive symptoms prior to surgery put patients at elevated risk forchronic pain and prolonged opioid use following surgery. The purpose of this preliminary study was to assess the efficacy of a one-day Acceptance and Commitment Therapy (ACT) workshop in "at-risk" Veterans for the prevention of chronic pain and opioid use following orthopedic surgery. In a randomized controlled trial, 88 at-risk Veterans undergoing orthopedic surgery were assigned to Treatment as Usual (TAU; N =44) or TAU plus a 1-day ACT workshop (N = 44)...

BACKGROUND: While gun-related penetrating traumatic brain injuries make up the majority of cranial missile injuries, low-velocity penetrating injuries present significant clinical difficulties that cannot necessarily be identically managed. Bow hunting is an increasingly popular pastime, and a crossbow allows a unique mechanism to cause a self-inflicted cranial injury with a large, low-velocity projectile. Historically, arrow removal is described in an operating room setting, which provides limited knowledge of the location of vascular injury in the setting of post-removal hemorrhage, and may represent an inefficient use of operating room availability...

BACKGROUND: Ebstein anomaly (EA) encompasses a broad spectrum of morphology and clinical presentation. Those who are symptomatic early in infancy are generally at highest risk, but there are limited data regarding multi-centric practice patterns and outcomes. We analyzed multi-institutional data concerning operations and outcomes in neonates and infants with EA. METHODS: Index operations reported in the STS Congenital Heart Surgery Database (2010-2016) were potentially eligible for inclusion...

Reoperations on the proximal thoracic aorta represent a challenge. The mortality rate is at least three times higher than it is for the initial surgery and the complications after such procedures occur with disappointingly high frequency, leading to substantial morbidity and delayed recovery. This article aims to present the early and the late outcomes of these kinds of operations, to identify the causes for failure of the primary surgery, to underline the critical points during the perioperative management of those patients and finally to emphasize on the rapid evolution and advent of techniques over the last few years...

BACKGROUND: Patients who have a proximal jejunostomy are difficult to manage because of their high stoma output which results in fluid and electrolyte imbalance with repeated hospital admissions and the necessity for expensive parenteral nutrition (PN). There are few reports on the use of re-feeding of the proximal effluents in this situation. METHODS: We here relate our experience with this manoeuvre in 35 patients between Jan 2010 and Feb 2016 who had stomas less than 120 cm away from the duodenojejunal flexure...

Fatigue has major implications on both patient safety and healthcare practitioner's well-being. Traditionally, two approaches can be used to reduce fatigue-related risk: reducing the likelihood of a fatigued operator working (i.e. fatigue reduction), or reducing the likelihood that a fatigued operator will make an error (i.e. fatigue proofing). Recent progress mainly focussed on fatigue reduction strategies such as reducing work hours. Yet it has to be recognized that such approach has not wholly overcome the experience of fatigue...

For the year 2017, more than 21,000 published references can be found in PubMed when entering the search term "cardiac surgery". This review focusses on conventional cardiac surgery, considering the new interventional techniques only if they were directly compared to classic techniques but also entails aspects of perioperative intensive care management. The publications last year provided a plethora of new and interesting information that helped to quantify classic surgical treatment effects and provided new guidelines for the management of structural heart disease, which made comparisons to interventional techniques easier...

BACKGROUND: The World Society for Emergency Surgery determined that for appendicitis managed with appendectomy, there is a paucity of evidence evaluating costs with respect to disease severity. The American Association for the Surgery of Trauma (AAST) disease severity grading system is valid and generalizable for appendicitis. We aimed to evaluate hospitalization costs incurred by patients with increasing disease severity as defined by the AAST. We hypothesized that increasing disease severity would be associated with greater cost...

BACKGROUND: Ureteropelvic junction obstruction (UPJO) is characterised by an obstruction compromising the passage of urine from the renal pelvis into the ureter, and can be corrected by Robot-Assisted Laparoscopic Pyeloplasty (RALP). We aimed to evaluate the surgical outcomes of RALP, and examine the rates of true pain resolution following the procedure. METHODS: We retrospectively explored the records of all patients who underwent RALP between April 2005 and January 2017...

Patient engagement in primary care leadership is an important means to involve community voices at community health centers. Federally qualified health centers (FQHCs) are mandated to have patient representation within their governing boards, while practices seeking patient-centered medical home certification receive credit for implementing patient advisory councils (PACs). Our objective was to compare and contrast how community health centers engage patients in clinic management, decision-making and planning within governing boards versus PACs...

#19
Andrew Emmanuel, Ezzat Chohda, Christo Lapa, Andrew Miles, Amyn Haji, Joe Ellul
BACKGROUND: Studies suggest that defunctioning stomas reduce the rate of anastomotic leakage and urgent reoperations after anterior resection. Although the magnitude of benefit appears to be limited, there has been a trend in recent years towards routinely creating defunctioning stomas. However, little is known about post-operative complication rates in patients with and without a defunctioning stoma. We compared overall short-term post-operative complications after low anterior resection in patients managed with a defunctioning stoma to those managed without a stoma...

Anatomical variants of muscle are commonly encountered by surgeons and radiologists. The flexor carpi radialis brevis (FCRB) is an anomalous muscle in the distal forearm with an estimated prevalence of 2-8%. In the literature, there are a few case reports of symptomatic FCRB tenosynovitis without a concomitant tear, and treatment methods described include both conservative and surgical management. We present a case of one patient with radial sided wrist pain and a partial FCRB tear, which to our knowledge is the first case report of a symptomatic FCRB tear...
