Impact of a Category-3 Hurricane on the Need for Surgical Hospital Care
Authors: Sjöberg Lina , Yearwood Robert 
Published: August 2016

AbstractIntroduction:Hurricane Ivan, a strong category-3 hurricane, struck Grenada on 07 September 2004 and devastated the country. Grenada is a small, developing country, whose socio-economic environment and health service is typical of most countries located within the Caribbean hurricane belt. Previous reports describing the consequences of hurricanes on health-related issues have focused mainly on the experience of wealthier countries.Objective:The objective of this study was to document the types of patients and medical problems faced by a hospital surgical service as a result of a forceful hurricane in a developing country and to help surgical divisions in developing countries prepare for strong hurricanes.Methods:This is a retrospective study using medical records from the surgical ward of the Grenada General Hospital. Patients admitted to the surgical ward during the month following Ivan were assessed with respect to diagnosis, age, gender, and length of hospitalization. The patients admitted during the same period the previous year were used as a control group.Results:The effects of the hurricane included a significant increase in the proportion of patients seen for diabetic feet, gunshot wounds, and infections due to wounds. The median length of the treatment time increased by 25%. In 2004, the total number of patients was 185 and in 2003, there were 167 patients admitted.Conclusions:The results of this study indicate that preparations for future hurricanes should include securing the capacity to handle the increased needs for hospital care, and ensuring that stocks of medicines, such as insulin and antibiotics, are sufficient, properly stored, and easily available to patients (e.g., by storing medicine at hurricane shelters equipped with generators and cold storage facilities). Diabetics should be instructed to use proper footwear to reduce the risk of cuts from debris.

Published: August 2016

AbstractIntroduction:No widely accepted, specialized medical training exists for police officers confronted with medical emergencies while under conditions of active threat. The purpose of this study was to assess medical decisionmaking capabilities of law enforcement personnel under these circumstances.Methods:Web-based surveys were administered to all sworn officers within the county jurisdiction.Thirty-eight key actions were predetermined for nine injured officer scenarios, with each correct action worth one point.Descriptive statistics and t-tests were used to analyze results.Results:Ninety-seven officers (65.1% response rate) responded to the survey. The majority of officers (68.0%) were trained to the first-responder level. Overall mean score for the scenarios was 15.5 ±3.6 (range 7–25). A higher level of medical training (EMT-B/P versus first responder) was associated with a higher mean score (16.6 ±3.4, p = 0.05 vs. 15.0 ±3.6, p = 0.05).Tactical unit assignment was associated with a lower score compared with nonassigned officers (13.5 ±2.9 vs. 16.0 ±3.6, p = 0.0085).No difference was noted based upon previous military experience. Ninety-two percent of respondents expressed interest in a law enforcement-oriented advanced first-aid course.Conclusions:Tactical medical decision-making capability, as assessed through the nine scenarios, was sub-optimal. In this post 9/11 era, development of law enforcement-specific medical training appears appropriate.

AbstractIntroduction:The Suwa Onbashira Festival is held every six years and draws approximately one million spectators from across Japan. Men ride the Onbashira pillars (logs) down steep slopes.At each festival, several people are crushed under the heavy log. During the 2004 festival, for the first time, a medical care system that coordinated a medical team, an emergency medical service, related agencies, and local hospitals was constructed.Objective:The aims of this study were to characterize the spectrum of injuries and illness and to evaluate the medical care system of this festival.Methods:The festival was held 02 April–10 May 2004. The medical records of all of the patients who presented to an on-site medical tent or who were treated at the scene and transported to hospitals over a 12-day period were reviewed.The following items were evaluated: (1) the emergency medical system at the festival; (2) the environmental circumstances; and (3) patient data.Results:All medical usage rates are reported as patients per 10,000 attendees (PPTT). A total 1.8 million spectators attended the festival during the 12-day study period; a total of 237 patients presented to the medical tent (1.32 PPTT), and 63 (27%) were transferred to hospitals (0.35 PPTT). Of the total, 135 (57%) suffered from trauma—two were severely injured with pelvic and cervical spine fractures; and 102 (43%) had medical problems including heat-related illness.Conclusions:Comprehensive medical care is essential for similar mass gatherings. The appropriate triage of patients can lead to efficient medical coverage.
Preparing for Burn Disasters: Predictors of Improved Perceptions of Competency after Mass Burn Care Training

Published: August 2016

AbstractIntroduction:Prehospital and community hospital healthcare providers in the United States must be prepared to respond to burn disasters. Continuing education is the most frequently utilized method of updating knowledge, skills, and competence among healthcare professionals. Since preparedness training must meet multiple educational demands, it is vital to understand how participants'work and educational experience and the program's content and delivery methods impact knowledge acquisition, and how learning influences confidence and competence to perform new skills.Purpose:The purpose of this exploratory, convenience sample study was to identify healthcare provider characteristics and continuing education training content areas that were predictive of self-reported improvement in competence after attending a mass-casualty burn disaster continuing education program.Methods:Logistic regression analysis of data from a post-training evaluation from nine, one-day continuing education conferences on mass burn care was used to identify factors associated with improved self-reported competency to respond to mass burn casualties.Results:The following factors were associated most closely with increased self-reported competency: (1) prehospital work setting (odds ratio (OR) = 3.06, confidence interval (CI) = 0.83–11.30, p = 0.09); (2) 11 or more years of practice (OR = 0.31, CI = 0.09–1.08, p = 0.07); and (3) practice in an urban setting (OR = 0.01, CI = 0.18–0.82, p >0.01). Confidence items included: (1) ability to implement appropriate airway management modalities (OR = 2.31, CI = 1.03–5.17, p >0.04); (2) manage patients with electrical injuries (OR = 4.86, CI = 1.84–12.85, p >0.001); (3) identify non-survivable injuries (OR = 2.24, CI = 0.93–5.43, p = 0.07); and (4) recognize special problems associated with burns in young children or older adults (OR = 2.14, CI = 0.87–5.23, p = 0.10). The final model explained 89.9% of the variability in self-reported competence.Conclusions:Interventions used to train healthcare providers for burn disasters must cover a broad range of topics. However, learning needs may vary by practice setting, work experience, and previous exposure to disaster events. This evaluation research provides three-fold information for continuing education research: (1) to identify content areas that should be emphasized in future burn care training; (2) to be used as a model for CE evaluation in other domains; and (3) to provide support that many factors must be considered when designing a CE program. Results may be useful to others who are planning CE training programs.

AbstractIntroduction:Morbidity and mortality due to acute but treatable conditions remain high in the developing world, as many significant barriers exist to providing emergency medical care.This study investigates these barriers in a rural region of Ethiopia.Hypothesis:The limited capacity of frontline healthcare workers to diagnose and treat acute medical and surgical conditions represents a major barrier to the provision of emergency care in rural Ethiopia.Methods:Health providers at a convenience sample of 16 rural health centers in the state of Tigray, Ethiopia completed a questionnaire designed to assess the availability of diagnostic and treatment modalities, the proximity and methods of transportation to referral facilities, and health providers' level of comfort in diagnosing and treating a variety of representative emergency medical conditions.Results:Thirteen (81%) providers had only a very basic level of medical training, and seven (44%) lacked access to any diagnostic equipment.While most providers could offer oral rehydration solution (ORS), anti-pyretic medications, and antibiotics, none of the providers could offer blood transfusions or any form of surgery. Ten (63%) respondents stated that their patients had to travel >10 km from the health center to a referral hospital, with only a minority of patients having access to motorized transport. For the seven emergency conditions assessed, a majority of providers felt comfortable diagnosing these conditions, though fewer felt comfortable treating them.Conclusion:There is a significant need for both health worker training and improvements in transportation infrastructure in order to increase access to emergency medical care in rural areas of the developing world.Low-cost interventions that improve human capacity in a context-appropriate manner are warranted as transportation and hospital network capacity expansions are considered.
Early milk ejection, prolonged parturition and periparturient oxytocin release in the pig

Published: August 2016

AbstractPlasma oxytocin was measured in 11 multiparous sows for 13 h after the start of parturition to confirm the existence of early milk ejections and determine whether they were associated with pulsatile oxytocin release. The relationship between oxytocin concentrations and duration of parturition was also analysed. Oxytocin was released in pulses during and after parturition and mean concentrations reached maximum 2 to 4 h after the first birth. Discrete milk ejections occurred during parturition but only 42% of these were associated with oxytocin peaks before 4 hpost partum. After this more than 80% of milk ejections occurred with oxytocin peaks. Sow grunting increased during milk ejections and peak grunt rate increased after parturition. Oxytocin peaks without milk ejections did not lead to an increased rate of grunting. Sows with prolonged parturition had lower basal and peak oxytocin concentrations. During the first 4 h only half of the piglets were born during an oxytocin peak. Discrete milk ejections with oxytocin peaks can occur before parturition is completed. However, during the first 4 hpost partum, basal oxytocin concentrations may be high enough for milk ejection to occur without further oxytocin secretion. Both milk ejection and oxytocin release are necessary for the sow to increase grunt rate. Low oxytocin concentration is associated with prolonged parturition.
New approaches to increasing oocyte yield from ruminants

Published: August 2016

AbstractArtificial insemination, superovulation and embryo transfer have had beneficial impacts on animal production but a limiting factor to realizing the full potential of these techniques and of other reproductive technologies is the availability of fertile oocytes. To overcome this problem, methods for maturing oocytesin vitro(IVM) have been developed. The production of bovine embryos by IVM is in commercial use but the rate of success and quality of embryos is low. The lack of success may be due to the quality of oocytes that are being matured and it would be preferable to utilize the abundant source of immature oocytes from preantral and primordial follicles by developing systems forin vitrogrowth (IVG). Several culture systems that utilize early growing follicles as a source of oocytes have been developed for laboratory species and these have been successful in producing live young. IVG in association with IVM and cryopreservation have the potential to maximize the genetic potential of high genetic merit females and shorten generation intervals. This paper presents the current status of technology for thein vitrogrowth and development of immature oocytes,in vitromaturation and cryopreservation of germ cells in domestic ruminants.
Nutritional effects on foetal growth

Published: August 2016

AbstractThe emphasis in nutritional studies on foetal growth has now moved from the last trimester of pregnancy, when most of the increase in foetal size takes place, to earlier stages of pregnancy that coincide with foetal organogenesis and tissue hyperplasia. At these stages absolute nutrient requirements for foetal growth are small but foetal metabolic activity and specific growth rate are high. It is thus a time when nutrient supply interacts with maternal factors such as size, body condition and degree of maturity to influence placental growth and set the subsequent pattern of nutrient partitioning between the gravid uterus and maternal body.Throughout pregnancy the maternal diet controls foetal growth both directly, by supplying essential nutrients and indirectly, by altering the expression of the maternal and foetal endocrine mechanisms that regulate the uptake and utilization of these nutrients by the conceptus. Nutritional effects on the endocrine environment of the embryo during the early stages of cell division can alter the subsequent foetal growth trajectory and size at birth; so too can current in vitro systems for oocyte maturation and embryo culture up to the blastocyst stage. There is increasing evidence that subtle alterations in nutrient supply during critical periods of embryonic and foetal life can impart a legacy of growth and developmental changes that affect neonatal survival and adult performance. Identifying the specific nutrients that programme these effects and understanding their mode of action should provide new management strategies for ensuring that nutritional regimens from oocyte to newborn are such that they maximize neonatal viability and enable animals to express their true genetic potential for production.

AbstractVarious dairy cattle production and health characteristics were studied with a view to identify easily available and measurable factors associated with the incidence of ketosis. The analyses were carried out using data from the Langhill Dairy Cattle Research Centre. Two approaches were used to assess the relative risk to cows of getting ketosis: one using information known at the beginning of lactation and one using information collected as the lactation progressed. In both approaches analyses were carried out using different amounts of the available information to simulate differences between recording systems. In the first approach the following were found to relate significantly to the level of recorded ketotic incidents: parity; ketosis in the previous lactation; calving condition score; 305-day milk yield in the previous lactation; and the average milk protein percentage in the previous lactation. The effects of these were quantified. In the second approach, where the change in ketosis incidence rate over the weeks of lactation was investigated, the average dry-matter intake in the previous week and changes in live weight and body condition score over the previous week were found to have a significant effect on the probability of getting ketosis in the coming week. The risk assessments varied depending on the information used and a flexible approach is recommended if potential risk factors are to be successfully incorporated into decision support systems.
Genetic variation of egg production traits in purebred and crossbred laying hens
Authors: Besbes B. , Gibson J. P. 
Published: August 2016

AbstractHeritabilities, dominance variation and genetic correlations (rpc) among purebred and crossbred performance were estimated for egg production (number of eggs produced between 19 and 25, 26 and 38 and 26 and 54 weeks of age) and egg quality traits (average egg weight, shell strength) in four generations of two nucleus lines of egg-laying chickens and their cross, all reared in similar environments. The within-line genetic parameters were estimated using method R applied to an animal model (approach 1) and tilde-hat approximation to restricted maximum likelihood applied to a sire-dam model (approach 2). The genetic correlation between purebred and crossbred performance as well as the crossbred heritabilities were estimated based on a multivariate sire-dam model accounting for all relationships. For egg numbers and shell strength, the purebred heritabilities were low to moderate (0·12 to 0·42). They were higher when estimated under an additive model (0·25 to 0·51) but, in general, lower than the crossbred heritabilities. For egg weight, the heritabilities were always high (0·6 to 0·7). The ratio of dominance variance to total genetic variance varied between 11 and 36% with approach 1 and 5 and 56% with approach 2, indicating a large partial dominance for egg number traits and shell strength but also the difficulty of accurately estimating the dominance variance. For these traits, the estimates of the correlation between purebred and crossbred performance, rpc, were quite high (0·8 to 0·94) which contradicts the theory that traits with larger dominance and/or difference between purebred and crossbred heritabilities present lower rpc. These high rpc estimates, coupled with the absence of obvious heterosis, indicate little advantage to be gained from use of crossbred data in genetic improvement, where pure lines and crossbreds are reared in a similar non-stressful environment.
Effects of an oat-based high-fibre diet on insulin, glucose, cortisol and free fatty acid concentrations in gilts

Published: August 2016

AbstractTo understand the mechanism underlying the effect of high-fibre diets on feeding motivation and stereotypic behaviour in pigs, non-pregnant gilts were given either concentrate or a high-fibre diet based on oat hulls and blood samples were assayed for cortisol, glucose, insulin and free fatty acids. The duration of eating was much longer for gilts on the high-fibre diet than gilts given concentrates. Concentrations of cortisol increased with food delivery and this was most pronounced with the concentrate diet. Concentrations of free fatty acids decreased before feeding and those of glucose and insulin decreased temporarily immediately after feeding began. The diet had no marked effect on these changes, although the decrease for insulin was less evident for the concentrate diet. As feeding continued, free fatty acid concentrations decreased, while concentrations of insulin and glucose increased. The increase in glucose and insulin was fastest with the concentrate diet, although post-feeding peak values did not differ. Postprandial cortisol and free fatty acid concentrations did not differ between diets. There was no evidence of a pre-prandial cephalic phase insulin or glucose response to feeding in the gilts although concentrations of both hormones decreased immediately after the gilts began to eat. The high-fibre diet tended to delay the peak glucose and insulin response to meals, suggesting that the reduced feeding motivation following consumption of high-fibre diets does not involve the same mechanism as the increased satiety following increased energy intake. As well as reducing the occurrence of ster eoty pies, high-fibre diets decrease cortisol concentrations at feeding.

AbstractEarly embryo loss is the major cause of reproductive failure in cattle. The effect of short-term changes in energy intake pre- and post-insemination on embryo survival and systemic progesterone was investigated in heifers. Two pasture allowances (low, L and high, H) were calculated on a dry-matter basis to provide 0⋅8 and 2⋅0 times maintenance requirements, respectively. Following oestrous synchronization, heifers (no. = 296) were allocated to either L or H pasture allowance for a 10 day period before artificial insemination (AI). On the day after AI, heifers (no. = 247) were again randomly allocated to either the L or H pasture allowance until either embryo recovery between days 14 to 16 or pregnancy diagnosis at day 30 (AI = day 0). Hence, there were four nutrition treatments; L-L, L-H, H-H and H-L. Blood samples were collected on days 4, 5, 6 and 7 of the pre- and days 4, 5, 6, 7, 13 and 14 of the post-AI oestrous cycle (oestrus = day 0) for determination of plasma progesterone. Embryo survival rate was significantly lower in the H-L (0⋅38) than in the L-L (0⋅70), L-H (0⋅71; P < 0⋅001) or H-H (0⋅65; P < 0⋅01) treatment groups but there was no evidence that the detrimental effect of reduced energy intake after AI was mediated through changes in systemic progesterone.
