Evaluación del bienestar equino en el centro militar de cría caballar de Écija (Sevilla)

El bienestar animal surge del conocimiento de los animales como seres que experimentan dolor, sufrimiento o estrés, la importancia del impacto en su salud, su comportamiento y también en su eficiencia reproductiva. La evaluación del bienestar incluye el comportamiento, la salud y la forma en la que los animales responden al manejo y a la gestión de sus condiciones de vida (alojamiento y alimentación). Bajo este estudio se desarrolla e implementa la evaluación del bienestar de los sementales y yeguas de cría de un centro de reproducción estatal, así como los potros de recría, futuros reproductores, mediante el estudio del efecto de las condiciones de manejo, para determinar cómo influyen las condiciones de vida sobre los indicadores de bienestar basados en el animal. Se utilizó un protocolo de evaluación según el modelo Welfare Quality® adaptado a la especie equina que incluye un total de 45 indicadores basados en el animal y basados en el ambiente, de una población total conformada por 196 animales del Centro Militar de Cría Caballar de Écija (Sevilla). Se evaluaron y compararon inicialmente las dos subpoblaciones de equinos adultos con aptitud reproductora constituida por 49 sementales estabulados y 43 yeguas de cría en semilibertad. Posteriormente, se realizó la evaluación de bienestar de 104 potros de recría futuros reproductores que vivían en libertad. Los resultados revelaron diferencias significativas en el estado de bienestar de los animales adultos sometidos a distintas condiciones de manejo. La evaluación del alojamiento y la alimentación puso de manifiesto que en los animales estabulados el área disponible para cada animal en las instalaciones era insuficiente y existía riesgo de lesión, dejaban restos de alimento y la condición corporal estaba aumentada. Se observaron sólo comportamientos anormales en los animales estabulados. También fueron más propensos a mostrar curiosidad en los test de comportamiento y también desviaciones de salud como el rascado en la crin y la cola, cojera, heridas en la región de las extremidades y problemas dentales, como los más destacados. Por el contrario, en las yeguas que vivían en semilibertad, se dieron reacciones de temor en los test de comportamiento, heridas distribuidas fundamentalmente por el cuello, tronco, grupa y regiones genitales, así como escalas de condición corporal disminuida. El análisis de los factores de riesgo usando un modelo de regresión, demostró cómo el manejo en semilibertad se asociaba a la aparición de ciertos trastornos de salud y desviaciones de comportamiento. En la población joven, destacaron las respuestas de curiosidad en los test de comportamiento, la presencia de heridas en las extremidades, descarga nasal, dolor en el dorso, pelos rotos en crin y cola y problemas generalizados de piel, entre otros. La metodología seguida para la evaluación del bienestar mediante la selección de un panel adecuado de indicadores permite determinar la incidencia de problemas de salud y comportamiento de la población reproductora y cómo influye el sistema de manejo, base para intervenciones futuras en la mejora del bienestar animal y su productividad como reproductores.

Evaluation of hemosponge in promoting dental socket healing after 3rd mandibular premolar extraction in a feline model

Aim: To investigate the healing process following use of collagen sponges in the dental socket after extraction. Wound complications during the study were also evaluated. Methods: 32 cats were included in this study. IV administration of the combination of diazepam (0.22 mg/kg) and ketamine (10 mg/kg) was used to induce general anesthesia. Surgical extraction of both 3rd mandibular premolars was performed. The open dental sockets were divided in two groups. In Group A, the open dental socket on the left side was closed using 4-0 Monocryl in simple interrupted pattern. In Group B, the right dental socket was filled with lyophilized hydrolyzed collagen and the buccal and lingual flaps were sutured using 4-0 Monocryl and simple interrupted pattern. Meloxicam (0.2 mg/kg) was used to manage the post-extraction pain in all cats. Ampicilline 20 mg/kg was used as prophylaxis. The wounds were observed during the study to evaluate any signs of inflammation or dehiscence. Radiographs were taken to compare healing of the socket 3 weeks after the procedure. A 1 mm biopsy punch sample was taken from sockets in all cats for comparison of the healing in both groups. Results: Hemorrhage occurred only in the sockets of Group A. Remission of radiolucent area occurred in both groups. Mean score of inflammation was lower and mean scores of fibrotic reaction and fibroplasia were higher in Group B (p<0.05). Conclusions: Use of hemosponge in alveolar socket may accelerate fibroplasia and formation of the connective tissue and reduce inflammation after tooth extraction. Therefore, post-extraction use of the hemostatic agent in the dental socket is recommended.

Transplantation of artificial gelatin-co-bletillastriata gelatin/Salvia miltiorrhiza Corium promotes dermal repair in rats

Purpose: To evaluate the growth of the composite corium (constructed with fibroblast cells and gelatinco- Bletillastriata gelatin/Salvia miltiorrhiza materials) on rats. Methods: The composite artificial corium was constructed by culturing fibroblast cells in gelatin-co- Bletillastriata gelatin/Salvia miltiorrhiza materials. Full-thickness area of skin was excised from the mice and subsequently, the composite corium was transplanted on the wound. Thereafter, the growth difference of the composite artificial corium and natural corium were compared. In addition, real-time fluorogenic reverse transcription polymerase chain reaction (qRT-PCR) and western blot were performed to determine vascular endothelial growth factor (VEGF) expression at gene and protein levels. Results: The composite artificial corium showed significant repair promoting effect on the skin, and the structure of the repaired skin was similar to that of natural corium. Interestingly, PCR and western blot results showed that the expressions of VEGF were higher in composite artificial corium than in natural corium on days 3 and 7 post-transplantation. Conclusion: The composite artificial corium has some clinical prospects for use in the treatment of wounds on large areas of skin.

Veteranness : Representations of Combat-related PTSD in U.S. Popular Visual Media

Posttraumatic stress and PTSD are becoming familiar terms to refer to what we often call the invisible wounds of war, yet these are recent additions to a popular discourse in which images of and ideas about combat-affected veterans have long circulated. A legacy of ideas about combat veterans and war trauma thus intersects with more recent clinical information about PTSD to become part of a discourse of visual media that has defined and continues to redefine veteran for popular audiences. In this dissertation I examine realist combat veteran representations in selected films and other visual media from three periods: during and after World Wars I and II (James Allen from I Am a Fugitive from a Chain Gang, Fred Derry and Al Stephenson from The Best Years of Our Lives); after the Vietnam War (Michael from The Deer Hunter, Eriksson from Casualties of War), and post 9/11 (Will James from The Hurt Locker, a collection of veterans from Wartorn: 1861-2010.) Employing a theoretical framework informed by visual media studies, Barthes’ concept of myth, and Foucault’s concept ofdiscursive unity, I analyze how these veteran representations are endowed with PTSD symptom-like behaviors and responses that seem reasonable and natural within the narrative arc. I contend that veteran myths appear through each veteran representation as the narrative develops and resolves. I argue that these veteran myths are many and varied but that they crystallize in a dominant veteran discourse, a discursive unity that I term veteranness. I further argue that veteranness entangles discrete categories such as veteran, combat veteran, and PTSD with veteran myths, often tying dominant discourse about combat-related PTSD to outdated or outmoded notions that significantly affect our attitudes about and treatment of veterans. A basic premise of my research is that unless and until we learn about the lasting effects of the trauma inherent to combat, we hinder our ability to fulfill our responsibilities to war veterans. A society that limits its understanding of posttraumatic stress, PTSD and post-war experiences of actual veterans affected by war trauma to veteranness or veteran myths risks normalizing or naturalizing an unexamined set of sociocultural expectations of all veterans, rendering them voice-less, invisible, and, ultimately disposable.

Nursing Interventions in Prevention and Healing of Leg Ulcers: Systematic Review of the Literature

Aim: The purpose of this study was to define nursing interventions for patients with venous, arterial or mixed leg ulcers. Methodology: A survey was conducted in EBSCO (CINAHL Plus with Full Text, MEDLINE with Full Text), MedicLatina, Academic Search Complete, with full text articles, published between 2008/01/01 and 2015/01/31, with the following keywords: [(MM "leg ulcer") OR (wound care) OR (wound healing)] AND [(nursing) OR (nursing assessment) OR (nursing intervention)]. Results: The different leg ulcer etiologies require different therapeutic approach to prevention and treatment. Predictive factors were identified associated with healing: patient-centred care, interpersonal relationship, pain control, control of the exudate, education for health self-management, self-care, therapeutic compliance, implementation of guidelines, auditing and feedback on the practices. Conclusion: Evidence-based practice helps to improve efficiency, safety and quality of nursing care directed to people with leg ulcers or at risk of developing this type of wounds.

PROVIDING OPTIMUM WOUND HEALING CONDITIONS DURING THE PROLIFERATIVE STAGE USING KERRAFIBRE

Abstract : In order to analyze the role of a new structured fibrous dressing in the proliferative stage of chronic wound healing in hard to heal wounds, a case study was performed on a stagnant venous ulcer, which remained non-healed in the past 7 months. All chronicity factors that could affect wound healing were excluded, including biofilm (with the use of polihexanide+betaine, Prontosan range), and compression therapy was provided. The results were very interesting with healing achieved in 7 weeks of treatment. Most of times it is not easy to find/select a dressing to promote granulation and epithelisation, once ideal cleaning/debridement and bioburden control are achieved. Some dressings do not provide a good healing rate, lead to bioburden elevation during time and recurrence in the use of antimicrobials. Other options to promote proliferation are very expensive and need a secondary dressing. Treatment with kerrafibre showned to be very cost effective. Its is also implicit the important role of advanced wound care centers versus conventional care.This case study was originally presented as a poster at Wounds UK 2014 Conference, at Harrogate, England, United Kingdom.

Assessment of Injuries Caused by Anastrepha fraterculus (Wied.) (Diptera: Tephritidae) on the Incidence of Bunch Rot Diseases in Table Grape.

Resumo: Anastrepha fraterculus (. Wied) é a principal praga de uvas de mesa (Vitis vinifera) na Região Sul do Brasil. Neste estudo, o objetivo foi investigar o efeito da punção de frutas por fêmeas adultas e infestação larvária por A. fraterculus na ocorrência da doença podridões na uva (cultivar "Itália"). Abstract: Anastrepha fraterculus (Wied.) is the main insect pest of table grapes (Vitis vinifera) in the Southern Region of Brazil. In this study, we aimed to investigate the effect of fruit puncturing by adult females and larval infestation by A. fraterculus on the occurrence of bunch rot disease in the grape (cultivar ?Itália?) by evaluating grapes (a) punctured for oviposition by females of A. fraterculus, sterilized in laboratory with novaluron (40 mg L−1) and further spray-inoculated separately with Botrytis cinerea (1 × 106 conidia mL−1), Glomerella cingulata (1 × 106 conidia mL−1), and bacteria and yeast that cause sour rot (1 × 105 cells mL−1), (b) grapes punctured for oviposition by non-sterilized females with pathogen spraying, (c) grapes with mechanical wounds and pathogen spraying, (d) grapes with no wounds and with pathogen spraying, (e) grapes punctured for oviposition by A. fraterculus chemically sterilized in laboratory with novaluron, (f) grapes punctured for oviposition by A. fraterculus non-sterilized in laboratory with novaluron, (g) grapes with mechanical wounds, and (h) grapes with no sterilization or pathogen spraying. Our data indicated that the mechanical and oviposition wounds caused by A. fraterculus increased the percentage of grapes infected by B. cinerea, G. cingulata, and microorganisms of acid rot. The grape puncturing by A. fraterculus and the mechanical wound allows the penetration of B. cinerea and microorganisms leading to acid rot. We conclude that the fruit fly A. fraterculus may facilitate phytopathogens penetration leading to bunch rots in the table grape Itália.
