ABSTRACT
We studied changes in chemical composition, somatic cell count, and immunoglobulin G (IgG) and M (IgM) content in red deer (Cervus elaphus) colostrum during the transition to milk at different times after parturition (<5 h, 24 h, 48 h, 2 wk, and 4 wk). The production level was higher at 2 and 4 wk of lactation than during the first day after parturition, with intermediate values at 48 h postpartum. Fat content did not vary during the study period. However, total protein and casein contents were particularly high in the initial 5 h after parturition, decreasing to approximately 50% after 24 h postpartum. Conversely, lactose concentration was low in the beginning (<5 h), increasing gradually throughout the study. Similarly, dry matter dropped during the first 24 h and then remained constant throughout the study. Urea content decreased during the study, showing a slight recovery at 4 wk. Somatic cell count was higher during the first hours after parturition and gradually decreased throughout the study period. The IgG content was higher before 5 h postpartum than at 24 h postpartum. After 5 h, the level of IgG decreased progressively until it reached 0.18 mg/mL at 4 wk of lactation. We observed a similar pattern for IgM content, but it decreased more quickly than IgG and was not detected after 2 wk. In the case of deer, milk should be considered transitional from 24 to 48 h after parturition, and samples collected after 2 wk can be considered mature milk.

OBJECTIVES: To evaluate benefits for the patient and the economic impact for the implementation of a wide awake local anesthesia no tourniquet (WALANT) hand surgery compared to traditional major outpatient circuit. METHODS: A prospective cohort study was planned comparing 150 cases of ambulatory hand surgery (carpal tunnel and trigger finger) using WALANT technique intervention out from the operating room; with another 150 which underwent intervention, outpatient setting, with preoperative evaluation, sedation and tourniquet, in the operation room. Preoperative, intraoperative and postoperative pain was monitored, as well as the days that required postoperative analgesia.The resources used and costs were evaluated. Satisfaction was evaluated using a specific survey. RESULTS: The pain during the surgery was equivalent for both groups and was significantly lower postoperatively for the WALANT group, with less need for the use of analgesics. Satisfaction was greater for the local anesthesia group. The use of personnel resources and hospital material was less for the WALANT group, with total saving calculated by 1,019 per patient. CONCLUSIONS: Procedures such as carpal tunnel surgery and trigger finger surgery can be safely performed using wide awake surgery. Patient satisfaction is higher to conventional procedure in the operation room. Pain control is excellent, especially during the postoperative period. WALANT technique for hand surgery represents a benefit for the patient in comfort, timeliness and no need for preoperative tests or evaluation. In addition, it represents a significant savings in hospital resources.

Supplementation with copper (Cu) improves deer antler characteristics, but it could modify meat quality and increase its Cu content to levels potentially harmful for humans. Here, we studied the effects of Cu bolus supplementation by means on quality and composition of sternocephalicus (ST) and rectus abdominis (RA) muscles (n=13 for each one) from yearling male red deer fed with a balanced diet. Each intraruminal bolus, containing 3.4 g of Cu, was administered orally in the treatment group to compare with the control group. Meat traits studied were pH at 24 h postmortem (pH24), colour, chemical composition, cholesterol content, fatty acid (FA) composition, amino acid (AA) profile and mineral content. In addition, the effect of Cu supplementation on mineral composition of liver and serum (at 0 and 90 days of treatment) was analysed. No interactions between Cu supplementation and muscle were observed for any trait. Supplementation with Cu increased the protein content of meat (P<0.01). However, Cu content of meat, liver and serum was not modified by supplementation. In fact, Cu content of meat (1.20 and 1.34 mg/kg for Cu supplemented and control deer, respectively) was much lower in both groups than 5 mg/kg of fresh weight allowed legally for food of animal origin. However, bolus of Cu tended to increase the meat content of zinc and significantly increased (P<0.05) the hepatic contents of sodium and lead. Muscles studied had different composition and characteristics. The RA muscle had significantly higher protein content (P<0.001), monounsaturated FA content (P<0.05) and essential/non-essential AA ratio (P<0.01) but lower pH24 (P<0.01) and polyunsaturated FA content (P=0.001) than the ST muscle. In addition, RA muscle had 14.4% less cholesterol (P=0.001) than ST muscle. Also, mineral profile differed between muscles with higher content of iron, significantly higher (P<0.001) content of zinc and lower content of calcium, magnesium and phosphorus (P<0.05) for ST muscle compared with RA. Therefore, supplementation with Cu modified deer meat characteristics, but it did not increase its concentration to toxic levels, making it a safe practice from this perspective. Despite the lower content of polyunsaturated FA, quality was better for RA than for ST muscle based on its higher content of protein with more essential/non-essential AA ratio and lower pH24 and cholesterol content.

This study describes the effects of Mn supplementation of 20 late-gestating and lactating Iberian red deer (Cervus elaphus hispanicus) females (hinds) fed a balanced diet on milk production and milk composition over the lactation period. Body weight of their calves at birth and at weaning was also evaluated. In addition, the effect of lactation stage was studied. For these purposes, 2 groups of hinds, one composed by 12 individuals (experimental) and the other by 8 individuals (control) were compared. Experimental hinds were s.c. injected weekly with Mn (2 mg Mn/kg BW) from day 140 of gestation until the end of lactation (week 18; forced weaning by physical separation). Control hinds were injected with a physiological saline solution with the same volume and at the same frequency as the experimental group. Serum Mn content of hinds was assessed just before the first Mn injection and at week 10 of lactation to assess whether the injected Mn increased Mn concentrations in blood. No differences were observed for BW of calves at birth but calves whose mothers were injected with Mn tended (P = 0.07) to have greater gain of BW from birth to weaning in proportion of BW at birth compared to calves from control hinds. In addition, supplementation with Mn increased (P ≤ 0.05) daily milk production by 10.2%, milk fat content by 11.2%, and total fat yield by 17.8%. Also, milk from hinds supplemented with Mn had more Ca (P < 0.001) and P (P < 0.05) than milk from control hinds. Manganese supplementation did not influence Mn serum content when blood was analyzed at week 10 of lactation, but increased the Mn content of milk by 18.3% (P < 0.001). Lactation stage affected (P < 0.001) fat, protein, lactose, and DM. Their contents increased as lactation proceeded, and protein was substituted by fat. Therefore, results suggest that Mn supplementation of hinds is recommended, even when they are fed a balanced diet, to increase milk production and the content of fat, Ca, P, and Mn of milk.

The main factors affecting the mechanical (and other) properties of bone, including antler, are the proportions of ash (especially Ca and P) and collagen content. However, some trace minerals may also play more important roles than would be expected, given their low levels in bone and antler. One such trace mineral is Cu. Here, we studied the effects of Cu supplementation on the mechanical and structural characteristics, and mineral content of antlers from yearling and adult (4 years of age) red deer fed a balanced diet. Deer (n=35) of different ages (21 yearlings and 14 adults) were studied. A total of 18 stags (11 yearlings and 7 adults) were injected with Cu (0.83 mg Cu/kg BW) every 42 days, whereas the remaining 17 (10 yearlings and 7 adults) were injected with physiological saline solution (control group). The Cu content of serum was analysed at the beginning of the trial and 84 days after the first injection to assess whether the injected Cu was mobilized in blood. Also, the mechanical and structural properties of antlers and the mineral content in their cortical walls were examined at three (yearlings) or four (adults) points along the antler beam. The effect of Cu supplementation was different in yearlings and adults. In yearlings, supplementation increased the Cu content of serum by 28%, but did not affect antler properties. However, in adults, Cu supplementation increased the Cu content of serum by 38% and tended to increase the cortical thickness of antlers (P=0.06). Therefore, we conclude that, even in animals receiving balanced diets, supplementation with Cu could increase antler cortical thickness in adult deer, although not in yearlings. This may improve the trophy value of antlers, as well as having potential implications for bones in elderly humans, should Cu supplementation have similar effects on bones as those observed in antlers.

The aim of this study was to investigate the effects of vitamin E (VE) supplementation and alfalfa grazing during fattening on fatty acid composition and mRNA expression of genes related to lipid metabolism in the LM of Rasa Aragonesa light lambs. After weaning, 48 lambs were kept indoors and fed a commercial concentrate and a VE supplemented concentrate (480 mg DL-α-tocopheryl acetate/kg DM) for 0 (control [CON]), 10 (VE10d), 20 (VE20d), and 30 d (VE30d) before slaughtering at 22 to 24 kg. Simultaneously, 8 unweaned lambs grazed in alfalfa (154 mg α-tocopherol/kg DM) paddocks with their dams and supplemented with the commercial concentrate (ALF). Immediately after slaughter, LM was sampled to determine gene expression. After 24 h of cooling at 4°C, LM was extracted to determine intramuscular fat (IMF) content and fatty acid composition. The IMF content did not differ with the dietary treatment ( = 0.212). Unweaned grazing alfalfa lambs had greater concentration of rumenic acid (C18:2 c9,t11; P < 0.001) and lower oleic acid (C18:1 c9; = 0.001) content and PUFA n-6:n-3 ratio (P < 0.001) but similar expression of genes implicated in lipid metabolism compared to the concentrate-fed lambs. Vitamin E supplementation did not modify muscle fatty acid composition; however, it increased the expression of FADS2 and ELOVL6, which are involved in desaturation of long-chain fatty acid and the elongation of SFA and MUFA. The results showed that a short period of VE supplementation, especially 10 (VE10d) and 20 d (VE20d), modified gene expression. Overall, the results showed that VE may be acting as a regulatory factor for transcriptional control of genes related to lipid metabolism in the muscle of Rasa Aragonesa light lambs (22-24 kg live weight and younger than 90 d old).

INTRODUCTION: Newborns with perinatal indicators of a potential hypoxic-ischemic event require an integrated care in order to control the aggravating factors of brain damage, and the early identification of candidates for hypothermia treatment. PATIENTS AND METHODS: The application of a prospective, populational program that organizes and systematizes medical care during the first 6 hours of life to all newborns over 35 weeks gestational age born with indicators of a perinatal hypoxic-ischemic insult. The program includes 12 hospitals (91,217 m2); two level I centers, five level II centers, and five level III hospitals. The program establishes four protocols: a) detection of the newborn with a potential hypoxic-ischemic insult, b) surveillance of the neurological repercussions and other organ involvement, c) control and treatment of complications, d) procedures and monitoring during transport. RESULTS: From June 2011 to June 2013, 213 of 32325 newborns above 35 weeks gestational age met the criteria of a potential hypoxic-ischemic insult (7.4/1000), with 92% of them being cared for following the program specifications. Moderate-severe hypoxic-ischemic encephalopathy was diagnosed in 33 cases (1/1,000), and 31 out of the 33 received treatment with hypothermia (94%). CONCLUSIONS: The program for the Integrated Care of Newborns with Perinatal Hypoxic-Ischemic Insult has led to providing a comprehensive care to the newborns with a suspected perinatal hypoxic-ischemic insult. Aggravators of brain damage have been controlled, and cases of moderate-severe hypoxic-ischemic encephalopathy have been detected, allowing the start of hypothermia treatment within the first six hours of life. Populational programs are fundamental to reducing the mortality and morbidity of hypoxic-ischemic encephalopathy

BACKGROUND: We report our initial gastric electrical stimulation experience using the abiliti® system for the treatment of obese patients followed for 1 year. METHOD: Between March 2011 and June 2013, 27 obese patients (BMI 30 to 46 kg/m(2)) were enrolled in a prospective open label study and implanted with a gastric stimulator. The patients were provided with nutritional support, and sensor-based behavioral feedback. RESULTS: At 12 months, percent excess weight loss (%EWL) obtained was 49.3 ± 19.2 % with no significant differences between gender or age sub-groups. The %EWL data were segmented into two groups according to BMI 30-40 kg/m(2) patients (obesity grade I and II) and BMI >40 kg/m(2), with the results of weight loss being significantly higher for the lower BMI group (59.1 ± 19.5 vs. 46.7 ± 13.4, respectively, p < 0.01). One subject requested to have his device explanted, and the minor postoperative adverse events were resolved without hospital admission. All patients experienced early satiety and reduced their intake. CONCLUSIONS: After 12 months of follow-up, gastric electrical stimulation treatment appears to be a safe and effective option for weight loss in obese subjects. Long-term follow-up and further studies are warranted.

The aim of this study was to investigate how different finishing period lengths with α-tocopherol supplementation or alfalfa grazing affect mRNA expression levels of genes related to vitamin E metabolism in L. thoracis (LT) muscle and subcutaneous fat (SF) from lambs of the Rasa Aragonesa breed. Indoors, concentrate-fed light lambs (n=48) were supplemented with 500 dl-α-tocopheryl acetate/kg concentrate for an average finishing period length of 0 (C), 10.7 (VE10d), 21.2 (VE20d) and, 32.3 (VE30d) days before slaughtering. Simultaneously, 8 lambs with their dams were alfalfa-grazed. The α-tocopherol affected in a short-term the expression of genes in LT muscle (ABCA1, LPL, APOE, and SREBP1) and SF (ABCA1, SCARB1, LPL, and PPARG). On the contrary, PPARA gene expression showed a long-term α-tocopherol effect because the highest levels of PPARA mRNA were found in the VE30d.

Oral health is dependent upon a thin mobile film of saliva on soft and hard tissues. Salivary proteins adhere to teeth to form the acquired enamel pellicle which is believed to protect teeth from acid erosion. This study investigated whether patients suffering diet-induced dental erosion had altered enamel pellicles. Thirty patients suffering erosion were compared to healthy age-matched controls. Subjects wore a maxillary splint holding hydroxyapatite and human enamel blocks for 1 h. The acquired enamel pellicle was removed from the blocks and compared to the natural incisor pellicle. Basic Erosive Wear Examination scores confirmed that dental erosion was present in erosion patients and absent from healthy age-matched controls. Erosion patients had half the amount of proteins (BCA assay) within the acquired pellicle forming on splint blocks compared to normal controls (p < 0.05). In particular, statherin, a calcium-binding protein, was 35% less abundant (p < 0.05). Calcium concentration within the acquired pellicle was also reduced by 50% in erosion patients (p < 0.001). In contrast, the natural pellicle on the incisor had similar amounts of total protein in erosion patients and healthy controls. In summary, the formation of new acquired pellicles on surfaces was reduced in erosion patients, which may explain their greater susceptibility to acid erosion of teeth.

In the follow-up of transplanted patients under immunosupression, the functional assessment of CD4+ T cells activation by measuring intracellular ATP levels in vitro, using the Immuknow test give information on how immune system is functioning. Therefore, it has been reported that low levels of ATP correlate with the risk of opportunistic infection. Although limited, comprehensive results in adult recipients as well as in pediatric transplanted patients have been reported. Forty stable liver pediatric transplanted patients (mean age: 11.0 years [SD 5.65]), within at least 1 year of transplant were selected for a scheduled review, and an unique determination of Immuknow was performed. Average ATP levels were 317 ng/mL (200-400 ng/mL) which were similar to the values observed in adult population. ATP values among patients with monotherapy Cyclosporin A (CSA) or tacrolimus (TAC) were significantly higher (P = .005) than in patients with double immunosupressive therapy using either CSA/TAC + Mycophenolate Mofetil (MMF). In CSA treatment, there are significant differences (P = .0003) between monotherapy and double therapy, but in the case of TAC we did not find differences (P > .1). A single determination of levels of ATP on CD4+ lymphocytes, can provide additional information that could be used as a complementary test to guide immunosuppressive therapy in paediatric liver transplant recipients.

The effect of feeding system on the expression of LPL, ACACA, FASN, FABP4, DGAT1, SCD, CPT1B, PRKAA2, LEP, SREBP1, PPARG, PPARA and CEBPB genes in semitendinous muscle was studied. Forty-four single born male lambs of the Rasa Aragonesa breed, allocated to four different dietary treatments, were used: grazing alfalfa, grazing alfalfa with supplement for lambs, indoor lambs with grazing ewes and drylot. Significant differences were found in the expression of genes LPL, ACACA, FASN, FABP4, CPT1B and SCD. Genes related to adipogenesis (LPL, ACACA, FASN, FABP4, and SCD) are up-regulated in the intensive groups. In grazing groups CPT1B gene expression, related to ß-oxidation process, is up-regulated. The relative expression of CPT1B was 1.54 fold higher in ALF+S, and 0.43 and 0.37 fold lower in IND- GRE and IND, respectively. The results support the hypothesis that changes in fatty acid profile due to feeding system implicate changes in the mRNA expression level of genes related with fat metabolism. Feeding strategy is an important tool to manipulate intramuscular fatty acid profile in meat through altering gene expression of enzymes related with fat metabolism.

INTRODUCTION: Therapeutic management of inborn errors of metabolism (IEMs) is complicated. The drugs involved are classified as orphan, and their supply depends on whether they are orphan medicines, investigational drugs, or need to be prepared as a compounded formula. MATERIALS AND METHODS: We analyzed emergency criteria, availability, and permanent location of metabolic drugs within the hospital. Information on therapeutic usage, administration, and dosage was also recorded. RESULTS: A stock for treating IEMs should include chelating agents, drugs to treat deficiencies, enzyme supplements, and other specific treatments. Hyperammonemia was considered to be life-threatening; therefore, an emergency supply of drugs to treat this condition should be kept permanently in the hospitalization unit. CONCLUSIONS: Emergency drug stocks are highly recommended in tertiary hospitals in order to improve care for patients susceptible to IEM.

Objetivos: Evaluar la mejora de la calidad de las prescripciones de quimioterapia para pacientes en ensayo clínico (EC) y analizar si en la orden médica se especifica la participación en el ensayo tras determinar los principales factores de riesgo y mediante la aplicación de medidas correctoras. Método: Estudio retrospectivo de omisiones recogidas durante 2006 y 2007. Con los datos del 2006 se analizaron los factores de riesgo y se implantaron medidas de mejora (información a prescriptores e inicio de prescripción electrónica). Posteriormente, se evaluaron los datos del 2007. Variables analizadas: EC, número de prescripciones, investigador principal, prescriptor, servicio, antineoplásicos y enfermedad. Resultados: Los servicios de Oncología y Hematología realizaron el 57,1% de los ensayos del hospital. En 2006 se recibieron 1.625 prescripciones y se detectaron 151 incorrectas (9,3%), y en 2007 se recibieron 1.858 prescripciones y se detectaron 65 incorrectas (3,5%). En 2006 se observó mayor frecuencia de prescripciones incorrectas en Hematología (34,1%) que en Oncología (8,6%). En 2007 Hematología apenas tuvo omisiones (1,8%) y en Oncología disminuyeron al 3,6%. Respecto a la enfermedad, la tasa de error desapareció prácticamente en mieloma múltiple (del 34,1 al 2,2%) y disminuyó en mama (del 10,8 al 4,4%). El incumplimiento siempre fue mayor cuando el prescriptor difería del investigador principal. Conclusiones: La frecuencia de las prescripciones con error se redujo (pasó del 9,3 al 3,5%). Destaca la reducción extraordinaria en Hematología relacionada con ensayos en mieloma múltiple. Las medidas correctoras han resultado útiles en la mejora de la calidad (AU)
Objectives: To assess the quality improvement of chemotherapy prescriptions for patients included in clinical trials (CT) analyzing whether the prescription is specified for patient participation, after having identified the major risks factors and the appropriate corrective measures are applied. Methods: Retrospective study of omissions collected during 2006 and 2007. After collecting all the information, we analyzed the risks factors and introduced improvement measures (information to prescribers and the beginning of electronic prescription). The 2007 data were then evaluated. Variables analyzed: CT, number of prescriptions, principal investigator, prescriber, department, anti-neoplastic involved and pathology. Results: Oncology and Haematology make up 57.1% of hospital trials. In 2006, 1625 chemotherapy prescriptions were received and there were 151 incorrect prescriptions (9.3%), and in 2007, 1858 prescriptions with 65 (3.5%) incorrect. In 2006, there was a higher frequency of incorrect prescriptions in Haematology (34.1%) and (Oncology (8.6%)). In 2007 Hematology had just 1.8% of omissions and in Oncology it decreased to 3.6%. As regards the pathology, the error rate has virtually disappeared in multiple myeloma prescriptions (34.1 to 2.2%) and decreased in breast cancer (10.8 to 4.4%). The non-fulfilment rate is higher when the prescriber is not the principal investigator. Conclusions: The overall frequency of prescriptions with errors decreased significantly from 9.3% to 3.5%, with an extraordinary reduction in Haematology (34.1% to 1.8%) related to the multiple myeloma trials. The corrective measures implemented have proved to be useful in CT (AU)

Two trials were conducted to study the effect of reducing the methionine (MET, 0.36 vs. 0.31%), linoleic acid (LIN, 1.60 vs. 1.12%), and supplemental fat (SFAT, 3.0 vs. 1.1%) content of isoenergetic diets on the productive performance and egg quality of brown laying hens late in the production cycle. The 8 treatments were arranged factorially (2 x 2 x 2), with 6 replicates of 20 hens per treatment (Hy-Line, from 59 to 70 wk of age in trial 1, and Lohmann, from 56 to 75 wk of age in trial 2). Except for SFAT content, dietary treatment had little effect on laying hen performance and egg quality. The only effect of a reduction in MET content on hen performance was the decrease in the percentage of large and extra large eggs (79.8 vs. 85.9%; P < 0.05) from 60 to 67 wk of age in trial 2. A decrease in the level of SFAT reduced egg production (79.3 vs. 77.0%; P < 0.05), egg weight (66.3 vs. 64.9 g; P < 0.001), egg mass (52.5 vs. 49.8 g/d; P < 0.001), feed conversion ratio (2.26 vs. 2.36 kg of feed/kg of eggs; P < 0.001), and percentage of extra large eggs (13.1 vs. 8.2%; P < 0.05) in trial 1, but no significant differences were detected in trial 2. Reducing the LIN content of the diet from 1.60 to 1.12% did not affect any trait in either of the 2 trials. We conclude that reducing the level of SFAT from 3.0 to 1.1% might decrease productivity and the percentage of extra large eggs. However, a reduction in the MET level from 0.36 to 0.31% and in LIN from 1.60 to 1.12% did not affect any trait in hens late in the production cycle. Eggshell quality was not affected by any of the dietary treatments.

A new kind of magnetic thermoseed for bone tissue engineering has been synthesized. The materials used are specially designed to restore bone tissue after tumor extirpation, because they exhibit bioactive behavior and the ability to act as thermoseeds for cancer treatment using hyperthermia. The L929 cell line of mouse fibroblasts has been used in a wide biocompatibility study concerning cell proliferation and morphology studies, mitochondrial function determination, lactate dehydrogenase measurement, and flow cytometry studies, including cell cycle analysis, cell size and complexity, and intracellular reactive oxygen species content. The results presented in this work indicate that these bioactive magnetic materials are highly biocompatible and show greater cell response for thermoseeds with a higher magnetic phase content. There were no significant alterations detected in the cell cycle, and the interaction between fibroblasts and the different mixtures did not induce significant apoptosis.
