Background The indication for surgery is justified by an expected improvement for the patient. To evaluate the probability and extent of individual postoperative patient benefit, the surgeon needs to elaborate numerous parameters of potential relevance for the outcome beyond his key competence, that is the technical dimension of the operation. Despite the highest medical standards, individual postoperative satisfaction with surgery is highly variable, even in cases with a technically good result. The aim of the present study was to investigate the individual predictability of postoperative pain and satisfaction in patients with elective musculoskeletal surgery...

The iSimangaliso Wetland Park World Heritage site, located on the east coast of South Africa, spans ∼3300 km(2) and constitutes the largest protected estuarine environment for hippopotami, crocodiles and aquatic birds in Africa. Given the ecological importance of this site and continued use of organochlorine pesticides (OCPs) in the region, this study focused on the nature, distribution and potential sources of organochlorine contamination within iSimangaliso Wetland Park. OCPs were widely distributed in surface sediment samples obtained from the four main Ramsar wetland systems within the park (Lake St Lucia, Mkhuze, Lake Sibaya and Kosi Bay)...

Dielectric barrier discharge (DBD)-based analytical applications have experienced rapid development in recent years. DBD designs and parameters and the application they are used for can vary considerably. This leads to a diverse field with many apparently unique systems that are all based on the same physical principle. The most significant changes among DBDs used for chemical analysis are in how the discharge electrodes are separated from the ignited discharge gas. While the official definition of a DBD states that at least one electrode has to be covered by a dielectric to be considered a DBD, configurations with both electrodes covered by dielectric layers can also be realized...

Gastric per oral endoscopic myotomy is a novel endoscopic technique, using mucosal incision and submucosal tunneling, to access and surgically divide the pyloric ring. It has been reported as a technically feasible procedure and minimally invasive therapy for refractory gastroparesis. We performed this procedure in a 63-year-old male patient with postoperative pylorospasm, with clinical success. Pylorospasm is one of pathophysiologic mechanisms underlying gastroparesis. As a subgroup of gastroparesis, pylorospasm should be identified to be an appropriate indication for gastric per oral endoscopic myotomy...

Core body temperature (CBT) is one of the main vital signs that is used to evaluate the health status of pigs. The most common and feasible method for assessing CBT in pigs is rectal temperature (RT). Obtaining RT is stressful for animals, may generate inaccurate results, and has the risk of spreading disease. Infrared imaging (IR) thermography of the body of pigs may be a safer and less stressful alternative to RT. The objective of the current study was to evaluate the efficacy of using IR as an alternative for monitoring CBT in pigs...

Current methods used for oral administration of pathogens to piglets are stressful for the animals because of fixation and use of inoculation methods such as oral gavage. In the present study an alternative way to challenge piglets with Typhimurium (ST) is investigated. The strategy was to incorporate the in a feed matrix, which is fed to the piglets and eaten voluntary. Different types of feed matrices were tested for their absorption capacity, handling properties, and palatability to piglets. Furthermore, the viability of ST in feed matrices was studied...

Through the process of enteric fermentation, cattle produce methane (CH), a potent greenhouse gas (GHG). Growing public concern about climate change has increased the need for accurate methods of measuring CH emissions from cattle directly to improve emission inventories and evaluate emissions mitigation techniques. The present study evaluated a ventilated head box system capable of measuring CH and carbon dioxide (CO) emissions, and oxygen (O) consumption from cattle. Six Holstein heifers were used to measure CH and CO emissions and O consumption from 2 ad libitum intake measurement periods (ADAPT and ADLIB) and 1 measurement period (RESTRICT) with intake restricted to 2% of BW on a DM basis...

Continuous recording over 24 h is an accurate method for behavioral measurements in ruminants but is very time-consuming. The aim of this study was to compare different recording rules, in particular continuous recording (CR) with different time samplings (TS) methods, when the behavior of growing heifers housed individually and fed a high-concentrate diet is recorded. Behavior of 8 growing heifers was recorded on 6 non-consecutive days. Continuous recording over 24 h, considered the control treatment, was used to evaluate TS methods by recording all the behaviors that occurred for 60 s at intervals of 2 (S2), 5 (S5), 10 (S10), 15 (S15), 20 (S20) and 30 (S30) min...

In the last 10 years, the microbial fuel cell (MFC) has been extensively studied worldwide to extract energy from wastewater via electricity generation. More recently, a merged technique of embedding MFC into a constructed wetland (CW) has been developed and appears to be increasingly investigated. The driving force to integrate these two technologies lies in the fact that CWs naturally possess a redox gradient (depending on flow direction and wetland depth), which is required by MFCs as anaerobic anode and aerobic cathode chambers...
