The present study was performed in order to evaluate the effects of lower than usual industry levels of dietary trace minerals on plasma levels, faecal excretion, performance, mortality and morbidity in growing-finishing pigs in a hot African climate. Group 1 (n =100 pigs) received a diet with common industry levels of trace minerals. Group 2 (n =100 pigs) received reduced dietary trace mineral levels but were fed the same basic diet as Group 1. Mortality, morbidity, pig performance and carcass measurements were evaluated. Two pigs in Group 1 and three pigs in Group 2 died. Thirteen pigs in Group 1 and 27 pigs in Group 2 were medically treated (P < 0.05). Carcass masses, back fat depth, loin depth, and lean percent were not significantly different between the groups. However, the carcasses when evaluated revealed a non-significant higher back fat thickness, lower loin eye area and percentage of fat free lean in barrows compared to gilts within each group. Despite lower initial masses, pigs fed diets containing industry levels of trace minerals were heavier (P < 0.05) and had a higher (P < 0.05) than average daily gains compared to those that received a diet containing lower levels of trace minerals. Faecal zinc excretion was significantly lower (P < 0.05) in pigs fed with lower dietary zinc levels. Copper, manganese and iron excretion were not affected (P > 0.05) by the dietary levels of these trace minerals. Plasma trace mineral concentrations were not affected by the dietary treatment.

ABSTRACT The plasma concentrations and episodic fluctuations of immunoreactive FSH and LH as well as the pituitary sensitivity to LH-RH stimulation were evaluated in post-menopausal women. The subjects were divided into 4 groups according to age. Group 1: 60–70 years old (n=11), group 2: 70–80 years old (n=22), group 3: 80–90 years old (n=31) and group 4: 90–100 years old (n=8). Standards used in gonadotrophin radioimmunoassays included the LER-907 preparation and a pooled post-menopausal serum. Since it was found that circulating gonadotrophins have an immunological pattern different from that shown by the pituitary preparation, the results were expressed in mIU/ml calculated accordingly to the immunological behaviour of pooled post-menopausal sera. The mean (± se) plasma levels of FSH (mIU/ml) were: group 1: 105.9 ± 9.5, group 2: 149.3 ± 10.5, group 3: 124.8 ± 7.1 and group 4: 149.4 ± 25.3. The mean (± se) plasma levels of LH (mIU/ml) were: group 1: 81.9 ± 12.5, group 2: 95.4 ± 9.9, group 3: 84.3 ± 7.7 and group 4: 113.5 ± 19.1. No statistically significant differences were observed among the 4 groups. One patient from each group was randomly selected in order to evaluate their LH and FSH episodic release as well as their pituitary responsiveness to exogenous stimulation. A pulsatile plasma pattern of gonadotrophin and a normal pituitary response to LH-RH injection were observed in the 4 patients studied. The results are interpreted as demonstrating that normal pituitary gonadotrophin function and pituitary reserve and responsiveness to exogenous stimulation are maintained in women of advanced age.

Background: Over one billion people have Hypertension (HTN); mortality and morbidity are increasing. The Parasympathetic and Sympathetic (P&S) nervous systems prominently affect the onset and progression of HTN, yet P&S measures are not used to assist in management. Our objective was to determine the feasibility of HTN control using P&S-guided to JNC 8 HTN therapy. Methods: 46 uncontrolled HTN patients were randomized prospectively to P&S-assisted management, adjusting JNC 8 therapy using the ANX 3.0 Autonomic Monitor and adding (r) Alpha Lipoic Acid (Group 1) vs. JNC 8 (Group 2). Results: The two Groups were similar in: 1) age (mean 66 vs. 70 y/o for Groups 1 and 2, respectively; 2) initial resting home Blood Pressure (BP, Group 1 mean=162/90 mmHg vs. Group 2 mean=166/87 mmHg, 3) initial resting office BP Group 1 mean=151/75 mmHg vs. Group 2 mean=155/73 mmHg, and 4) ethnicity. Upon follow-up (mean=8.35 mo.): 1) mean resting home BPs were 145/77 mmHg (Group 1, 74% of patients at JNC 8 goal) vs. 155/83.5 mmHg (Group 2, 30.4% at JNC 8 goal), and 2) mean resting office BPs were 138/71 mmHg (Group 1) vs. 146/65 mmHg (Group 2). At the studys conclusion, Group 1 Sympathetic tone was lower than that for Group 2 both at rest and upon standing, and Group 1 Parasympathetic tone was higher than that for Group 2 both at rest and upon standing. Conclusion: P&S-assisted HTN therapy is feasible, resulting in improved BP control, through healthier P&S tone on fewer prescription medications.

Induction of remission is easily achieved with dietary treatment in dogs diagnosed with Food Responsive Chronic Diarrhea (FRD). Administration of prebiotics and glycosaminoglycans (GAGs) may improve epithelial cell integrity and therefore be useful as adjunct treatment. This study evaluated whether the relapse rate of FRD dogs that are switched back to a normal diet can be influenced using supplemental treatment with prebiotics and GAGs. A randomized, controlled clinical trial (RCCT) was performed in dogs diagnosed with FRD. Dogs were diagnosed based on clinical exclusion diagnosis, endoscopic biopsies showing predominantly lymphoplasmacytic infiltration, and response to dietary treatment. Dogs were randomized to be fed a combination of prebiotics and GAGs (group 1) or placebo (group 2) in addition to a hydrolyzed diet. At week 10, a second endoscopy was performed and dogs were switched back to normal diet. Relapse rate was monitored every 2 weeks after that until week 18. Statistical analysis was performed for each outcome (Canine Chronic Enteropathy Clinical Activity Index (CCECAI), clinicopathological data, endoscopic scoring, mWSAVA histological scoring index (mWSAVA), and number of relapses following switch to normal diet) using a linear mixed effects model for group comparison. Time, group, and their interactions were included as a fixed effect, whereas each dog was treated as a random effect. Of the 35 dogs enrolled into the clinical trial, 10 in each group reached the point of second endoscopy. A total of 13 dogs (n = 8 in group 1 and n = 5 in group 2) reached the trial endpoint of 18 weeks. After switching back to normal diet, none of the dogs in either group relapsed. No significant differences were found over time or between groups for CCECAI, endoscopy scoring and histological scoring. Although there was a clinical worsening in the placebo group after switching back to the original diet, this was not statistically significant (CCECAI p = 0.58). Post-hoc power calculation revealed that 63 dogs per group would have been needed to detect statistically significant differences in CIBDAI between treatment groups. Standard dietary treatment induced rapid clinical response in all cases, however, additional supplementation with prebiotics and GAGs did not significantly improve clinical outcome within 4 months after switching back to normal diet. Since there are very few RCCT published in CE in dogs, this pilot study provides important power analyses for planning of further studies.

Background The aim of this study was to compare the outcomes of a primary and secondary Bentall-De Bono procedure. Methods From 2008 to 2015 (8-year period), 308 patients underwent a Bentall-De Bono procedure in our institute. The mean age was 43 ± 13 years and 80% were men. Twenty-eight patients had prior cardiac surgery through a median sternotomy (group 1) and 280 underwent a primary Bentall-De Bono procedure (group 2). Various preoperative and perioperative parameters were analyzed before and after propensity-score matching. Results Before propensity-score matching, patients undergoing a secondary Bentall-De Bono procedure had a worse preoperative profile, as indicated by a higher EuroSCORE II ( p < 0.0001), with hospital mortality in group 1 of 14% (4/28) and 5% (14/280) in group 2 ( p = 0.069). After propensity-score matching, there was no significant difference in EuroSCORE II ( p = 0.922) or hospital mortality ( p = 0.729). After adjusting for the different variables, repeat sternotomy could not be identified as an independent predictor of postoperative mortality or morbidity. Survival at the end of 1 and 5 years in both groups showed no significant differences before or after propensity-score matching ( p = 0.328 and p = 0.356, respectively). In Cox multivariable regression analysis, reoperation was not identified as an independent factor for survival before ( p = 0.559) or after propensity-score matching ( p = 0.365). Conclusion A secondary Bentall-De Bono procedure can be performed with acceptable mortality and morbidity, and with midterm survival rates comparable to those of a primary Bentall-De Bono procedure.

Objective The aim of this study is to compare neonatal mortality and morbidity in multiple and singleton preterm/very low birthweight (PT/VLBW) multiethnic Asian infants. Study Design Cohort study of 676 singleton and 299 multiple PT/VLBW infants born between 2008 and 2012 at KK Women's and Children's Hospital, the largest tertiary perinatal center in Singapore with further stratification by gestational ages 23 to 25 (Group 1), 26 to 28 (Group 2), and ≥29 (Group 3) weeks. Outcome measures included predischarge mortality and major neonatal morbidity. Results Overall survival to discharge was comparable for singletons 611/676 (90%) and multiples 273/299 (91%). Use of assisted reproductive technologies (47 vs. 4%), antenatal steroids (80 vs. 68%), and delivery by cesarean section (84 vs. 62%) were significantly higher (p < 0.001) in multiples while pregnancy induced hypertension (8.7 vs. 31.6%, p < 0.001) and maternal chorioamnionitis (31 vs. 41%, p < 0.01) were seen less commonly compared with singleton pregnancies. Survival was comparable between singletons and multiples except for a lower survival in multiples in Group 2 (81.7 vs. 92.4%, p = 0.007). Major neonatal morbidities were comparable for multiples and singletons in the overall cohort. Presence of hemodynamically significant patent ductus arteriosus (HsPDA) requiring treatment (88.9 vs. 72.5%), air leaks (33 vs. 14.6%, p = 0.02), NEC (30 vs. 14.6%, p = 0.04), and composite morbidity (86 vs. 66%, p = 0.031) were significantly higher in multiples in Group 1. A significantly higher incidence of HsPDA (68.1 vs. 52.4%, p = 0.008) was also observed in multiples in Group 2. Multiple pregnancy was not an independent predictor of an adverse outcome on regression analysis (OR: 0.685, 95% confidence interval: 0.629–2.02) even in GA ≤25 weeks. Conclusion Neonatal mortality and morbidity were comparable in our cohort of PT/VLBW singletons and multiple births, but preterm multiple births ≤25 weeks had a higher incidence of neonatal morbidity.

Abstract Introduction: It has been reported that as compared with total intravenous anesthesia (TIVA), inhalation anesthesia is increasing the postoperative level of proinflammatory interleukins. The aim of the study is to investigate if there is an in-vivo relationship between proinflammatory cytokines, Interleukin- 32 (IL-32) and Tumour necrosis factor - α (TNF- α), in patients undergoing laparoscopic cholecystectomies with two different anesthetic techniques, TIVA or inhalation anesthesia. Material and Methods: Twenty two consecutive patients undergoing laparoscopic cholecystectomies were prospectively randomized into two groups: Group 1: TIVA with target-controlled infusion (TIVA-TCI) (n=11) and Group 2: isoflurane anesthesia (ISO) (n=11). IL-32 and TNF-α were determined before the induction of anesthesia (T1), before incision (T2) and at 2h (T3) and 24h (T4) postoperatively. Our primary outcome was to compare plasma levels of IL-32 and TNF- α concentrations (expressed as area-under-the-curve) over 24 hours between study groups. Our secondary outcome was to establish whether there is a correlation between plasma levels of IL-32 and of TNF-α at each time point between the two groups. Results: Area-under-the-curve (AUC) of IL-32 plasma concentration was 7.53 in Group 1 (TIVA) versus 3.80 in Group 2 (ISO), p= 1. For TNF-α, AUC of plasma concentration was 733.9 in Group 1 (TIVA) and 668.7 in Group 2 (ISO), p= 0.066. There were no significant differences in plasma concentrations of both IL-32 and TNF- α between the groups. Conclusions: IL-32 expression in response to minor surgery is very low. There were no significant difference between plasma levels ofTNF- α and IL-32 after TIVA versus inhalation anesthesia during the first 24 hours postoperatively. Further studies are needed on larger groups to investigate whether there can be a correlation between these interleukins after 2 different anesthetic techniques and the impact of this correlation on postoperative outcome.

INTRODUCTION Labor pain is very frequent in clinical practice, but the underlying mechanisms as well as numerous neuroendocrine responses activated by such pain have not been fully explained yet. OBJECTIVE The objective of the study was to determine the influence of labor pain on plasma levels of cortisol and opioid peptide ?-endorphin. METHOD Cortisol and ?-endorphin levels were measured in blood plasma of: health, non-pregnant women (group 1, n=8), health pregnant women (group 2, n=8) and in parturitions, through fourth ages (group 3, n=8), Plasma level of cortisol was measured by radioimmunoassay, and ?-endorphin by enzyme immunoassay. Data were expressed as mean ? standard error of mean and were analyzed by Student's t test and Mann Whitney test. RESULTS Plasma level of cortisol in group 2 was significantly increased compared to the group 1. During labor progression, plasma level of cortisol was rising till the third labor age. Plasma level of cortisol in fourth labor age was not significantly different from the ag.e one and group 1. Plasma level of ?-endorphin was (n.g/L): in group 1:64?20, group 2:70?22, group 3:the first labor age: 75?15, the second labor age: 193?54, the third labor age: 346+97 and the fourth labor age: 114?31. CONCLUSION These results indicate that both ?-endorphin and cortisol are involved in regulation and modulation of labor pain and stress.

The first line of treatment of obstructive sleep apnoea syndrome (OSAS) in children consists of adenotonsillectomy (T&A). The aim of the present study was to evaluate treatment outcomes of OSAS among obese children recruited from the community.A cross-sectional, prospective, multicentre study of Spanish obese children aged 3–14 years, with four groups available for follow-up: group 1: non-OSAS with no treatment; group 2: dietary treatment; group 3: surgical treatment; and group 4: continuous positive airway pressure treatment.117 obese children (60 boys, 57 girls) with a mean age of 11.3±2.9 years completed the initial (T0) and follow-up (T1)assessments. Their mean body mass index (BMI) at T1was 27.6±4.7 kg·m−2, corresponding to a BMI Z-score of 1.34±0.59. Mean respiratory disturbance index (RDI) at follow-up was 3.3±3.9 events·h−1. Among group 1 children, 21.2% had an RDI ≥3 events·h−1at T1, the latter being present in 50% of group 2, and 43.5% in group 3. In the binary logistic regression model, age emerged as a significant risk factor for residual OSAS (odds ratio 1.49, 95% confidence interval 1.01–2.23; p<0.05) in obese children surgically treated, and RDI at T0as well as an increase in BMI emerged as significant risk factors for persistent OSAS in obese children with dietary treatment (OR 1.82, 95% CI 1.09–3.02 (p<0.03) and OR 8.71, 95% CI 1.24–61.17 (p=0.03)).Age, RDI at diagnosis and obesity are risk factors for relatively unfavourable OSAS treatment outcomes at follow-up.

To investigate the secretion of the plasma levels of atrial natriuretic peptide (ANP) in patients with acute myocardial infarction (AMI), we evaluated the relationship between plasma levels of ANP and pulmonary capillary wedge pressure (PCWP) in 45 consecutive patients during the acute phase of AMI (∼12 h after the attack) ( group 1) and compared data with those obtained after 1 mo ( group 2). In both groups 1and 2, plasma ANP levels significantly correlated with PCWP. The slope of the linear regression line between the PCWP and ANP in group 1 was significantly lower, by about one-third, than that in group 2. In addition, we examined changes in ANP levels and left ventricular end-diastolic pressure (LVEDP) over 180 min after AMI induced by injection of microspheres into the left coronary arteries of three dogs. The LVEDP and ANP levels 30 min after AMI were significantly higher than those before; however, despite the persistent high LVEDP during the 180 min after AMI, ANP levels decreased gradually and significantly to 63% of the peak level at 150 min. These findings suggest that the secretion of ANP during the acute phase of myocardial infarction may be insufficient relative to the chronic phase.
