Three metazoan parasites, a monogenean Hexostoma thynni and two species of copepods Pseudocycnus appendiculatus and Euryphorus brachypterus are known to parasitize the gills of ranched southern bluefin tuna (SBT) and other tuna species. However, there is no detailed information describing the pathological response to infection by these parasites in this species. Wild southern bluefin tuna Thunnus maccoyii (approximately 3 years of age), captured and towed to a grow-out site in the waters immediately south of Port Lincoln, South Australia were subsequently sampled (n = 10) monthly from March until August 2004 during commercial harvest operations...

BACKGROUND: There is no consensus on reporting non-mortality trauma complications in a graded manner. The Clavien-Dindo scale of complications was originally for elective surgery, and requires adaptation to provide meaningful data for trauma patients. In particular the original score does not account for those treated without surgery. We report an adapted Clavien-Dindo in trauma (ACDiT) scale and apply it to patients managed operatively and non-operatively. METHODS: A combined prospective and retrospective international multi-center observational study was undertaken to apply the ACDiT scale to 484 trauma patients at 3 university teaching hospitals (Birmingham, England (n=303); Houston, Texas (n=113); and Glasgow, Scotland (n=68))...

BACKGROUND *: Despite limited data regarding the indications and effectiveness of percutaneous cholecystostomy (PC) in the treatment of acute cholecystitis (AC), usage has increased by over 500% since 1994. Many of these patients subsequently undergo interval cholecystectomy (IC), a procedure that has not been rigorously evaluated. This aim of this study was to quantify the morbidity and mortality associated with the IC. METHODS *: We included all consecutive adult patients (>18 years old) who underwent PC and IC from January 2008 to December 2013...

BACKGROUND: Severe injuries of the uterus may trigger uterine scar formation, ultimately leading to infertility or obstetrical complications. To date, few methods have adequately solved the problem of collagen deposition in uterine scars. Umbilical cord-derived mesenchymal stem cells (UC-MSCs) have shown great promise in clinical applications. The objective of this study was to investigate the effect of a scaffold/UC-MSCs construct on collagen degradation and functional regeneration in rat uterine scars following full-thickness excision of uterine walls...

In totally laparoscopic distal gastrectomy (TLDG) for gastric cancer, accurately determining the proximal resection line may be difficult. This is because identifying the lesion intracorporeally is impossible, due to the lack of tactile sense, and, in addition, unlike the intestine, the most proximal site of the lesion is often different from the main site due to the distorted shape of the stomach. The aim of this study was to introduce a novel method of preoperative endoscopic marking with India ink, taking into consideration the morphological characteristics of the stomach...

BACKGROUND: Current diagnostic tools for prostate cancer lack specificity and sensitivity for detecting very early lesions. DNA methylation is a stable genomic modification that is detectable in peripheral patient fluids such as urine and blood plasma that could serve as a non-invasive diagnostic biomarker for prostate cancer. METHODS: We measured genome-wide DNA methylation patterns in 73 clinically annotated fresh-frozen prostate cancers and 63 benign-adjacent prostate tissues using the Illumina Infinium HumanMethylation450 BeadChip array...

The aim of this study was to present our experiences with patients operated on for the recurrence of papillary thyroid cancer with the combined use of preoperative ultrasonographic mapping and radioguided occult lesion localization (ROLL). Twenty patients who had already undergone total thyroidectomy and central/lateral neck dissection for papillary thyroid carcinoma were reoperated on due to locoregional metastasis. The patients with proven recurrences and high Tg wash-out levels in cytopathologic aspirates were operated on...

BACKGROUND & AIMS: Despite evidence that most non-malignant colorectal polyps can be managed endoscopically, a substantial proportion of patients with a non-malignant colorectal polyp are still sent to surgery. Risks associated with this surgery are not well characterized. We aimed to describe 30-day post-operative morbidity and mortality and to explore risk factors for adverse events in patients undergoing surgical resection for non-malignant colorectal polyps. METHODS: We analyzed data collected prospectively as part of the National Surgical Quality Improvement Program...

Vesa Selonen, Ralf Wistbacka
The lifetime movements of an individual determine the gene flow and invasion potential of the species. However, sex dependence of dispersal and selective pressures driving dispersal have gained much more attention than dispersal at different life and age stages. Natal dispersal is more common than dispersal between breeding attempts, but breeding dispersal may be promoted by resource availability and competition. Here, we utilize mark-recapture data on the nest-box population of Siberian flying squirrels to analyze lifetime dispersal patterns...

BACKGROUND: Women have blamed epidurals for their post-partum back pain for decades. Survey-based studies have shown similar incidence of chronic back pain between women who delivered with epidurals compared to those who did not. However, epidural insertion site pain has yet to be evaluated by a quantitative measure: pressure pain threshold (PPT). Algometer measured PPT has been shown to be accurate and reproducible in acute, chronic, and post-operative pain studies. This study determines the effect of ultrasound-based landmarks on the PPT at the epidural insertion site in the postpartum period...

BACKGROUND: Surgical site marking is one important cornerstone for the principles of safe surgery suggested by the WHO. Generally it is recommended that the attending surgeon performs the surgical site marking. Particularly in the case of same day surgery, this recommendation is almost not feasible. Therefore we systematically monitored, whether surgical site marking can be performed by trained nursing staff. The aim of the study was to find out whether surgical site marking can be carried out reliably and correctly by nurses...

BACKGROUND: Photochemical tissue bonding (PTB) is a sutureless, light-activated technique that produces a watertight, microvascular repair with minimal inflammation compared to standard microsurgery. However, it is practically limited by the need for a clinically viable luminal support system. The aim of this study was to evaluate a hollow biocompatible stent to provide adequate luminal support to facilitate vascular anastomosis using the PTB technique. METHODS: Forty rats underwent unilateral femoral artery transection...

BACKGROUND: Alveolar cleft reconstruction using iliac crest bone graft(ICBG) is considered standard of care for children with complete cleft lip and palate at the time of mixed dentition. Harvesting bone may result in donor site morbidity, additional operating time and length of hospitalization. Recombinant human bone morphogenetic protein(rhBMP)-2 with a demineralized bone matrix(DBM) was used as an alternative bone source for alveolar cleft reconstruction. We investigate the outcomes of rhBMP-2/DBM versus ICBG for alveolar cleft reconstruction by reviewing postoperative surgical complications and cleft closure...

BACKGROUND: Organisms that are isolated from vaginal cuff infections and pelvic abscesses after hysterectomy frequently include anaerobic vaginal flora. Metronidazole has outstanding coverage against nearly all anaerobic species, which is superior to both cefazolin and second-generation cephalosporins. Cefazolin plus metronidazole has been demonstrated to reduce infectious morbidity compared with either cefazolin or second-generation cephalosporins in other clean-contaminated procedures, which include both as colorectal surgery and cesarean delivery...

The purpose of this study is to investigate the effects of well-field hydraulics and permeability heterogeneity on mass-removal efficiency for systems comprising large groundwater contaminant plumes. A three-dimensional (3D) numerical model was used to simulate the impact of different well-field configurations on pump-and-treat mass removal for heterogeneous domains. The relationship between reduction in contaminant mass discharge (CMDR) and mass removal (MR) was used as the metric to examine remediation efficiency...
