    Acute progressive feed restriction (APFR) represents a specific form of caloric restriction in which feed availability is increasingly curtailed over a period of a few days to a few weeks. It is often used for control animals in toxicological and pharmacological studies on compounds causing body weight loss to equalize weight changes between experimental and control groups and thereby, intuitively, to also set their metabolic states to the same phase. However, scientific justification for this procedure is lacking. In the present study, we analyzed by microarrays the impact on hepatic gene expression in rats of two APFR regimens that caused identical diminution of body weight (19%) but differed slightly in duration (4 vs. 10 days). In addition, white adipose tissue (WAT) was also subjected to the transcriptomic analysis on day-4. The data revealed that the two regimens led to distinct patterns of differentially expressed genes in liver, albeit some major pathways of energy metabolism were similarly affected (particularly fatty acid and amino acid catabolism). The reason for the divergence appeared to be entrainment by the longer APFR protocol of peripheral oscillator genes, which resulted in derailment of circadian rhythms and consequent interaction of altered diurnal fluctuations with metabolic adjustments in gene expression activities. WAT proved to be highly unresponsive to the 4-day APFR as only 17 mRNA levels were influenced by the treatment. This study demonstrates that body weight is a poor proxy of metabolic state and that the customary protocols of feed restriction can lead to rhythm entrainment

    Full Text Available Background. The purpose of this study of preterm infants was to test the effect of four approaches to the time of transition from gavage to full oral feedings, time to discharge, and weight gain during the transition. Methods. A randomized experimental design was used with four intervention groups: early start (32 weeks’ postmenstrual age/slow progressing experience (gradually increasing oral feedings offered per day; early start/maximum experience (oral feedings offered at every feeding opportunity; late start (34 weeks’ postmenstrual age/slow progressing experience; and late start/maximum experience. Results. The analysis included 86 preterm infants. Once oral feedings were initiated, infants in the late start/maximum experience group achieved full oral feeding and were discharged to home significantly sooner than infants in either early start group. Although not significantly different, these infants also achieved these outcomes sooner than infants in the late start/slow progressing experience group. There were no differences in weight gain across groups. Conclusions. Results suggest starting oral feedings later in preterm infants may result in more rapid transition to full oral feedings and discharge although not at early postnatal ages. Provision of a more consistent approach to oral feeding may support infant neurodevelopment and reduce length of hospitalization.

    The aim of this study was to compare the efficacy of neuromuscular electrical stimulation (NMES) in addition to traditional dysphagia therapy (TDT) including progressive resistance training (PRT) with that of TDT/PRT alone during inpatient rehabilitation for treatment of feeding tube-dependent dysphagia in patients who have had an acute stroke. This study is an inpatient rehabilitation case-control study involving 92 patients who have had an acute stroke with initial Functional Oral Intake Scale (FOIS) scores of 3 or lower and profound to severe feeding tube-dependent dysphagia. Sixty-five patients, the NMES group, received NMES with TDT/PRT, and 27 patients, the case-control group, received only TDT/PRT. Treatment occurred in hourly sessions daily for a mean ± SD of 18 ± 3 days. χ(2) Analyses/t tests revealed no significant statistical differences between the groups for age (t = -0.85; P = 0.40), sex (χ(2) = 0.05; P = 0.94), and stroke location (χ(2) = 4.2; P = 0.24). A Mann-Whitney U test revealed a statistically significant difference between the groups for the initial FOIS score (z = -2.4; P = 0.015), with the NMES group having worse initial scores with a mean rank of 42.64 and the case-control TDT/PRT group having a mean rank of 55.8. The main outcome measure was the comparison of the FOIS scores after treatment. The mean ± SD FOIS score after NMES with TDT/PRT treatment was 5.1 ± 1.8 compared with 3.3 ± 2.2 in the case-control TDT/PRT group. The mean gain for the NMES group was 4.4 points; and for the case-control group, 2.4 points. Significant improvement in swallowing performance was found for the NMES group compared with the TDT/PRT group (z = 3.64; P rehabilitation in reducing feeding tube-dependent dysphagia in patients who have had an acute stroke.

    Acute renal failure can be caused by calcineurin inhibitors (CNIs), due to arteriolopathy and altered tubular function. Within this context, we present the case of a 14-month-old liver transplant recipient who suffered an acute polyuric renal failure during a short episode of hypercaloric feeding. In our case, CNI-induced distal RTA led to nephrocalcinosis and therefore to secondary nephrogenic diabetes insipidus. The diet with high renal solute load consequently resulted in an acute polyuric...

    Acute pancreatitis is among the most common and costly reasons for hospitalization in the United States. Bowel rest, pain control, and intravenous fluids are the cornerstones of treatment, but early feeding might also be beneficial. To compare length of hospital stay, mortality, and readmission in adults hospitalized with pancreatitis who received early versus delayed feeding. MEDLINE via Ovid, EMBASE, the Cochrane Library, CINAHL, and Web of Science through January 2017. Two authors independently reviewed and selected studies if they were randomized clinical trials, included adults hospitalized with acute pancreatitis, and compared early versus delayed feeding (≤48 vs. >48 hours after hospitalization). Two investigators independently extracted study data and rated risk of bias using the Cochrane Collaboration tool. Eleven randomized trials (8 peer-reviewed publications, 3 abstract-only presentations) that included 948 patients were eligible. Seven trials (3 with low risk of bias) enrolled patients with mild to moderate pancreatitis. Four trials (1 with low risk of bias) included patients with predicted severe pancreatitis. Routes used for early feeding included oral (4 studies), nasogastric (2 studies), nasojejunal (4 studies), and oral or nasoenteric (1 study). Among patients with mild to moderate pancreatitis, early feeding was associated with reduced length of stay in 4 of 7 studies (including 2 of 3 with low risk of bias). Other outcomes were heterogeneous and variably reported, but no study showed an increase in adverse events with early feeding. Among patients with severe pancreatitis, limited evidence revealed no statistically significant difference in outcomes between early and delayed feeding. Heterogeneity of feeding protocols and outcomes, scant data, and unclear or high risk of bias in several studies. Limited data suggest that early feeding in patients with acute pancreatitis does not seem to increase adverse events and, for patients with mild to

    Several types of feeding tubes can be placed at a patient's bedside; examples include nasogastric, nasointestinal, gastrostomy, and jejunostomy tubes. Nasoenteral tubes can be placed blindly at bedside or with the assistance of placement devices. Nasoenteric tubes can also be placed via fluoroscopy and endoscopy. Gastrostomy and jejunostomy tubes can be placed using endoscopic techniques. This paper will describe the indications and contraindications for different types of tubes that can be placed at the bedside and complications associated with tube placement. Complications associated with nasoenteral tubes include inadvertent malpositioning of the tube, epistaxis, sinusitis, inadvertent tube removal, tube clogging, tube-feeding-associated diarrhea, and aspiration pneumonia. Complications from percutaneous gastrostomy and jejunostomy tube placements include procedure-related mishaps, site infection, leakage, buried bumper syndrome, tube malfunction, and inadvertent removal. These complications will be reviewed, along with a discussion of incidence, cause, treatment, and prevention approaches.

    Recent clinical studies have shown that nasogastric tube feeding is safe in the majority of patients with acute pancreatitis. Patient-reported outcomes are important, but the impact of nasogastric tube feeding on the quality of life has not been investigated. This study aims to compare quality of life between nasogastric tube feeding and nil-by-mouth groups during and after hospitalization. Patient-reported outcomes were recorded daily in a patient diary during hospitalization. The Abdominal Surgery Impact Scale questionnaire was used to determine patients' quality of life. The patients were then followed up at 1 week and 1, 3, and 6 months after discharge. While 17 patients were randomized to nasogastric tube feeding, 18 were put on nil-by-mouth. The overall quality of life and individual domains did not differ significantly between the groups during hospitalization (P = .500) or follow-up. For the entire cohort, individual quality-of-life domains during hospitalization improved significantly, including functional impairment (P nasogastric tube feeding, in comparison with nil-by-mouth, does not impair patients' quality of life. Given the clinical benefits of nasogastric tube feeding, nasogastric feeding should be considered the first-line approach in all acute pancreatitis patients requiring enteral nutrition. © 2015 American Society for Parenteral and Enteral Nutrition.

    OBJECTIVE--To compare percutaneous endoscopic gastrostomy and nasogastric tube feeding after acute dysphagic stroke. DESIGN--Randomised prospective study of inpatients with acute stroke requiring enteral nutrition. SETTING--One university hospital (Nottingham) and one district general hospital (Derby). SUBJECTS--30 patients with persisting dysphagia at 14 days after acute stroke: 16 patients were randomised to gastrostomy tube feeding and 14 to nasogastric tube feeding. MAIN OUTCOME MEASURES--Six week mortality; amount of feed administered; change in nutritional state; treatment failure; and length of hospital stay. RESULTS--Mortality at 6 weeks was significantly lower in the gastrostomy group with two deaths (12%) compared with eight deaths (57%) in the nasogastric group (P nasogastric patients lost at least one day's feed. Nasogastric patients received a significantly (P tube showed greater improvement in nutritional state, according to several different criteria at six weeks compared with the nasogastric group. In the gastrostomy group the mean albumin concentration increased from 27.1 g/l (24.5 g/l to 29.7 g/l) to 30.1 g/l (28.3 g/l to 31.9 g/l). In contrast, among the nasogastric group there was a reduction from 31.4 g/l (28.6 g/l to 34.2 g/l) to 22.3 g/l (20.7 g/l to 23.9 g/l) (P nasogastric group (P indicates that early gastrostomy tube feeding is greatly superior to nasogastric tube feeding and should be the nutritional treatment of choice for patients with acute dysphagic stroke.

    Diagnosis, treatment, response monitoring, and outcome of pediatric acute myeloid leukemia (AML) have made enormous progress during the past decades. Because AML is a rare type of childhood cancer, with an incidence of approximately seven occurrences per 1 million children annually, national and international collaborative efforts have evolved. This overview describes these efforts and includes a summary of the history and contributions of each of the main collaborative pediatric AML groups worldwide. The focus is on translational and clinical research, which includes past, current, and future clinical trials. Separate sections concern acute promyelocytic leukemia, myeloid leukemia of Down syndrome, and relapsed AML. A plethora of novel antileukemic agents that have emerged, including new classes of drugs, are summarized as well. Finally, an important aspect of the treatment of pediatric AML--supportive care--and late effects are discussed. The future is bright, with a wide range of emerging innovative therapies and with more and more international collaboration that ultimately aim to cure all children with AML, with fewer adverse effects and without late effects. © 2015 by American Society of Clinical Oncology.

    In mild acute pancreatitis, traditional treatment has been initial fasting and oral refeeding with clear liquids to prevent adverse gastrointestinal events such as pain. The diet is gradually progressed to soft solids and hospital discharge is planned based on patients' tolerance to a solid diet. To determine the length of hospitalization and tolerance to oral refeeding when initiated on a soft diet as compared to a clear liquid diet. One hundred and one patients with mild acute pancreatitis were randomized to receive either a clear liquid diet or soft diet when oral feeding was initiated. Frequency of pain, total and postrefeeding length of hospitalization, and dietary intake were monitored. Hospital discharge was decided by the medical team without input from the study coordinators. A statistically significant decrease in the length of hospitalization (total and postrefeeding) of a median of 2 days was seen in patients receiving a soft diet (P < 0.001). No significant difference in the need for cessation of diet because of pain was observed between the two groups. Patients initiated on a soft diet consumed significantly more calories and fats on study day 1 (P < 0.001). Oral refeeding with a soft diet in patients with mild acute pancreatitis can be considered safe and can result in shorter length of hospitalization.

    Full Text Available Background. Information regarding the progression of acute hepatitis B virus (HBV infection to chronic infection in adults is scarce. Methods. Twenty-five adult patients with acute HBV infection (14 men and 11 women, 18–84 years old, whose clinical features progressed to those of chronic infection (group A or did not (group B, were studied retrospectively. Results. There were 3 and 22 patients in groups A and B, respectively. Two of the 3 patients of group A lacked the typical symptoms of acute hepatitis. No differences were found between groups with respect to age, sex, or HBV genotypes. However, total bilirubin and alanine aminotransaminase levels were significantly lower in group A. Conclusions. Three of the 25 adult patients with acute HBV infection progressed to chronic infection. Hepatitis was mild in these patients. Patients with mild acute hepatitis B or unapparent HBV infection may have a higher risk of progressing to chronic infection.

    Growth is essential for very low birth weight infants. The purpose of this retrospective chart review was to evaluate the impact of a new standardized, evidenced-based feeding protocol for infants born < 1500 g in correlation with growth and clinical outcomes. Growth and nutrition data was reviewed from 2 groups of infants born < 1500 g within a level III newborn intensive care unit (NICU). Epoch 1 infants (N = 32) received care following initial implementation of a standardized enteral feeding protocol. Epoch 2 infants (N = 32) received care following aggressive modification of this initial protocol based on newly available literature that promotes earlier initiation and advancement of enteral feedings. Epoch 2 infants weighed more at 36 weeks (2562 vs 2304 g) with higher discharge weight percentiles (32nd vs 15th percentile). Epoch 2 infants started and achieved full enteral feedings earlier (day of life 1 vs 4; 7 vs 22, P < 0.0001) and required less days of parenteral nutrition (5.5 vs 17.5 days, P < 0.0001), with indwelling central line for parenteral access (6 vs 17.5). There were no differences in retinopathy of prematurity (17% control vs 19% study), oxygen requirement at 36 weeks (22% epoch 1 vs 43%), necrotizing enterocolitis (3% epoch 1 vs 0%), intraventricular hemorrhage grade 3-4, periventricular leukomalacia, or death. In this sample of very low birth weight infants, a progressive standardized, evidence-based feeding protocol was associated with improved growth without increased risk for necrotizing enterocolitis. © 2018 American Society for Parenteral and Enteral Nutrition.

    Full Text Available Cerebellar ataxias represent a wide group of neurological diseases secondary to dysfunctions of cerebellum or its associated pathways, rarely coursing with acute-onset acquired etiologies and chronic non-progressive presentation. We evaluated patients with acquired non-progressive cerebellar ataxia that presented previous acute or subacute onset. Clinical and neuroimaging characterization of adult patients with acquired non-progressive ataxia were performed. Five patients were identified with the phenotype of acquired non-progressive ataxia. Most patients presented with a juvenile to adult-onset acute to subacute appendicular and truncal cerebellar ataxia with mild to moderate cerebellar or olivopontocerebellar atrophy. Establishing the etiology of the acute triggering events of such ataxias is complex. Non-progressive ataxia in adults must be distinguished from hereditary ataxias.

    Full Text Available Acute pancreatitis is considered an autodigestive disorder in which inappropriate activation of trypsinogen to trypsin within pancreatic acinar cells leads to the development of pancreatitis. Autophagy is an evolutionarily preserved degradation process of cytoplasmic cellular constituents, and it is one of the early pathological processes in acute pancreatitis. Autophagic flux is impaired in acute pancreatitis, which mediates the key pathologic responses of this disease. Impaired autophagy, dysfunction of lysosomes, and dysregulation of autophagy suggest a disorder of the endolysosomal pathway in acute pancreatitis. The role of autophagy in acute pancreatitis is discussed from the aspects of autophagic process, autophagy and activation of trypsinogen, impaired autophagy and acute pancreatitis, and defective autophagy promoting inflammation.

    2017-01-01

    Full Text Available Acute renal failure can be caused by calcineurin inhibitors (CNIs, due to arteriolopathy and altered tubular function. Within this context, we present the case of a 14-month-old liver transplant recipient who suffered an acute polyuric renal failure during a short episode of hypercaloric feeding. In our case, CNI-induced distal RTA led to nephrocalcinosis and therefore to secondary nephrogenic diabetes insipidus. The diet with high renal solute load consequently resulted in an acute polyuric renal failure with severe hypernatremic dehydration. In conclusion, a hypercaloric diet in children with potentially impaired renal function due to therapy with CNIs requires precise calculation of the potential renal solute load and the associated fluid requirements.

    Full Text Available Progressive motor deficits are relatively common in acute pontine infarction and frequently associated with increased functional disability. However, the factors that affect the progression of clinical motor weakness are largely unknown. Previous studies have suggested that pontine infarctions are caused mainly by basilar artery stenosis and penetrating artery disease. Recently, lower pons lesions in patients with acute pontine infarctions have been reported to be related to progressive motor deficits, and ensuing that damage to the corticospinal tracts may be responsible for the worsening of neurological symptoms. Here, we review studies on motor weakness progression in pontine infarction and discuss the mechanisms that may underlie the neurologic worsening.

    Proxies have the potential to accelerate feed efficiency (residual feed intake (RFI); kg dry matter/day) improvement, assisting with the reduction of beef cattle feed costs and environmental impact. Heart rate (HR) (beats per minute (BPM)) is associated with feed efficiency and influenced by autonomic activity and peripheral metabolism, suggesting HR could be used as a proxy for feed efficiency. Objectives were to assess associations between overnight HR, lying patterns and RFI, and between acute stress HR and RFI. Heifer calves (n=107; 408±28 days of age, 341±42.2 kg) and yearling heifers (n=36; 604±92 days of age, 539±52.2 kg) were exposed to a performance test to determine productive performance. Overnight HR (electrode based) and lying patterns (accelerometer based) were monitored on a subgroup of heifer calves (n=40; 20 lowest RFI; 20 highest RFI). In the 10-min acute stress assessment, all heifers were individually exposed to the opening and closing of an umbrella and HR before (HRBEF), in response to (HRMAX), after (HRAFT) and change (HRCHG; HRAFT-HRBEF) as a result of exposure were determined. Using polynomial regression, rate of HR decrease pre-exposure (β 1) and rates of HR increase (β 2) and decrease (β 3, β 4) post-exposure were determined. Heifer calves in the overnight assessment were classified into equal RFI groups (low RFI; high RFI) and HR means were treated as repeated measures and compared using multiple regression. In the acute stress assessment, heifers were classified within cattle category into equal RFI groups (low RFI; high RFI) and means and polynomial regression parameters were compared using multiple regression. Low-RFI heifer calves had a lower overnight HR (69.2 v. 72.6 BPM), similar HR change from lying to standing intervals (8.9 v. 9.2 BPM) and similar time lying (61.1% v. 64.5%) compared with high-RFI heifer calves. Low-RFI heifer calves had a higher absolute HRMAX (162.9 v. 145.7 BPM) and β 2 (-0.34 v. -0.20) than high

    Knowledge about acute pancreatitis has increased recently in both the medical and veterinary fields. Despite this expansion of knowledge, there are very few studies on treatment interventions in naturally occurring disease in dogs. As a result, treatment recommendations are largely extrapolated from experimental rodent models or general critical care principles. General treatment principles involve replacing fluid losses, maintaining hydrostatic pressure, controlling nausea and providing pain relief. Specific interventions recently advocated in human medicine include the use of neurokinin-1 antagonists for analgesia and early interventional feeding. The premise for early feeding is to improve the health of the intestinal tract, as unhealthy enterocytes are thought to perpetuate systemic inflammation. The evidence for early interventional feeding is not supported by robust clinical trials to date, but in humans there is evidence that it reduces hospitalisation time and in dogs it is well tolerated. This article summarises the major areas of management of acute pancreatitis in dogs and examines the level of evidence for each recommendation. © 2015 British Small Animal Veterinary Association.

    Central oxytocin reduces food intake and increases energy expenditure. The ventromedial hypothalamic nucleus (VMN) is associated with energy balance and contains a high density of oxytocin receptors. We hypothesized that oxytocin in the VMN is a negative regulator of energy balance acting to reduce feeding and increase energy expenditure. To test this idea, oxytocin or vehicle was injected directly into the VMN of Sprague-Dawley rats during fasted and nonfasted conditions. Energy expenditure (via indirect calorimetry) and spontaneous physical activity (SPA) were recorded simultaneously. Animals were also exposed to a conditioned taste aversion test, to determine whether oxytocin's effects on food intake were associated with malaise. When food was available during testing, oxytocin-induced elevations in energy expenditure lasted for 1 h, after which overall energy expenditure was reduced. In the absence of food during the testing period, oxytocin similarly increased energy expenditure during the first hour, but differences in 12-h energy expenditure were eliminated, implying that the differences may have been due to the thermic effects of feeding (digestion, absorption, and metabolic processing). Oxytocin acutely elevated SPA and reduced feeding at doses that did not cause a conditioned taste aversion during both the fed and fasted states. Together, these data suggest that oxytocin in the VMN promotes satiety and acutely elevates energy expenditure and SPA and implicates the VMN as a relevant site for the antiobesity effects of oxytocin.

    Feeding is a basic component of care and it is the most common and difficult management issue for stroke patients. Objective of this study was to know the practice of feeding (oral & nasogastric tube feeding), different types of food used and their caloric value in stroke patients. This direct observational study was done from June 2010 to November 2010, in different medicine wards of Dhaka Medical College Hospital, and included 100 acute stroke patients confirmed by CT scan or MRI of brain and duration of hospital stay for at least 24 hours. Out of 100 cases, 22% took their feeding orally and 78% cases through nasogastric tube. Artificial milk powder 66% cases (NG tube vs. Orally, 58% vs. 8%), juice 18% (NG tube 13% vs. orally 5%), horlicks & juice & soup 10% (NG tube vs. Orally, 7% vs. 3%), khichury 2% orally, bread & egg & shuji 4% cases orally. In 100 cases studied, none of them fulfilled the calorie requirement up to the standard level according to the guideline of Nutrition & Food Science Institute, of Dhaka University, Bangladesh. Though this study was small scale but the magnitude of under nutrition among stroke patients revealed is alarming and needs urgent attention.

  16. INHIBITION OF FATTY ACID DESATURASES IN Drosophila melanogaster LARVAE BLOCKS FEEDING AND DEVELOPMENTAL PROGRESSION.

    Fatty acid desaturases are metabolic setscrews. To study their systemic impact on growth in Drosophila melanogaster, we inhibited fatty acid desaturases using the inhibitor CAY10566. As expected, the amount of desaturated lipids is reduced in larvae fed with CAY10566. These animals cease feeding soon after hatching, and their growth is strongly attenuated. A starvation program is not launched, but the expression of distinct metabolic genes is activated, possibly to mobilize storage material. Without attaining the normal size, inhibitor-fed larvae molt to the next stage indicating that the steroid hormone ecdysone triggers molting correctly. Nevertheless, after molting, expression of ecdysone-dependent regulators is not induced. While control larvae molt a second time, these larvae fail to do so and die after few days of straying. These effects are similar to those observed in experiments using larvae deficient for the fatty acid desaturase1 gene. Based on these data, we propose that the ratio of saturated to unsaturated fatty acids adjusts a sensor system that directs feeding behavior. We also hypothesize that loss of fatty acid desaturase activity leads to a block of the genetic program of development progression indirectly by switching on a metabolic compensation program. © 2016 Wiley Periodicals, Inc.

    Tolerance of oral food is an important criterion for hospital discharge in patients with acute pancreatitis. Patients who develop oral feeding intolerance have prolonged hospitalisation, use additional healthcare resources, and have impaired quality of life. This study aimed to quantify the incidence of oral feeding intolerance, the effect of confounders, and determine the best predictors of oral feeding intolerance. Clinical studies indexed in three electronic databases (EMBASE, MEDLINE, and the Cochrane Central Register of Controlled Trials) were reviewed. Incidence and predictor data were meta-analysed and possible confounders were investigated by meta-regression analysis. A total of 22 studies with 2024 patients met the inclusion criteria, 17 of which (with 1550 patients) were suitable for meta-analysis. The incidence of oral feeding intolerance was 16.3%, and was not affected by WHO region, age, sex, or aetiology of acute pancreatitis. Nine of the 22 studies investigated a total of 62 different predictors of oral feeding intolerance. Serum lipase level prior to refeeding, pleural effusions, (peri)pancreatic collections, Ranson score, and Balthazar score were found to be statistically significant in meta-analyses. Oral feeding intolerance affects approximately 1 in 6 patients with acute pancreatitis. Serum lipase levels of more than 2.5 times the upper limit of normal prior to refeeding is a potentially useful threshold to identify patients at high risk of developing oral feeding intolerance.

    Full Text Available Herbivore feeding elicits dramatic increases in defenses, most of which require jasmonate (JA signaling, and against which specialist herbivores are thought to be better adapted than generalist herbivores. Unbiased transcriptional analyses of how neonate larvae cope with these induced plant defenses are lacking.We created cDNA microarrays for Manduca sexta and Heliothis virescens separately, by spotting normalized midgut-specific cDNA libraries created from larvae that fed for 24 hours on MeJA-elicited wild-type (WT Nicotiana attenuata plants. These microarrays were hybridized with labeled probes from neonates that fed for 24 hours on WT and isogenic plants progressively silenced in JA-mediated defenses (N: nicotine; N/PI: N and trypsin protease inhibitors; JA: all JA-mediated defenses. H. virescens neonates regulated 16 times more genes than did M. sexta neonates when they fed on plants silenced in JA-mediated defenses, and for both species, the greater the number of defenses silenced in the host plant (JA > N/PI > N, the greater were the number of transcripts regulated in the larvae. M. sexta larvae tended to down-regulate while H. virescens larvae up- and down-regulated transcripts from the same functional categories of genes. M. sexta larvae regulated transcripts in a diet-specific manner, while H. virescens larvae regulated a similar suite of transcripts across all diet types.The observations are consistent with the expectation that specialists are better adapted than generalist herbivores to the defense responses elicited in their host plants by their feeding. While M. sexta larvae appear to be better adapted to N. attenuata's defenses, some of the elicited responses remain effective defenses against both herbivore species. The regulated genes provide novel insights into larval adaptations to N. attenuata's induced defenses, and represent potential targets for plant-mediated RNAi to falsify hypotheses about the process of adaptation.

    Malaysia enacted the Renewable Energy Act in April 2011. One of its important components is the feed-in tariff (FiT) scheme—launched in December 2011. The scheme is managed and administered by the Sustainable Energy Development Authority (SEDA) of Malaysia. This paper analyses the impact of the FiT mechanism in Malaysia a year after its implementation; particularly on the installation and economical aspects. First, the history of the scheme is presented before summarising the application process for the scheme. Next, a detailed evaluation on the implication of the scheme is discussed. Some of the key findings from the analysis include: (i) the uptake for renewable energy installations has been extremely high, particularly for solar photovoltaic installation; (ii) the foreign and domestic direct investment related to renewable sectors have increased significantly; (iii) more ‘green’ jobs have been created, particularly in the manufacturing and installation sectors, and (iv) there are plans to include wind and thermal energy in the FiT scheme. It can be concluded that the FiT scheme in Malaysia has produced significant impact during the first year of its implementation. With a proper monitoring by SEDA and more awareness among the people, renewable energy will most likely flourish in Malaysia. - Highlights: • Malaysia launched the feed-in tariff (FiT) scheme in December 2011. • The one year progress is evaluated in terms of installation and economical aspects. • The uptake for renewable energy installations has been extremely high. • Investment related to renewable sectors has increased significantly. • More ‘green’ jobs have been created in the country

    Acute myeloid leukemia (AML) is an acquired disease characterized by chromosomal translocations and somatic mutations that lead to leukemogenesis. Systemic combination chemotherapy with an anthracycline and cytarabine remains the standard induction regimen for "fit" adults. Patients who achieve complete remission generally receive postinduction therapy with cytarabine-based chemotherapy or an allogeneic bone marrow transplant. Those unfit for induction chemotherapy are treated with hypomethylating agents (HMAs), low-dose cytarabine, or they are offered supportive care alone with transfusions and prophylactic antimicrobials. The revolution in understanding the genetics of AML, facilitated by next-generation sequencing, has led to many new drugs against driver mutations. Better methods of identification of leukemic blasts have provided us with better means to detect the disease left behind after cytotoxic chemotherapy regimens. This measurable residual disease has been correlated with poorer relapse-free survival, demonstrating the need for novel strategies to eradicate it to improve the outcome of patients with acute leukemias. In this article, we discuss adapting and improving AML therapy by age and comorbidities, emerging targeted therapies in AML, and minimal residual disease (MRD) assessment in AML.

    Diaphragm atrophy is associated with delayed weaning from mechanical ventilation and increased mortality in critically ill adults. We sought to test for the presence of diaphragm atrophy in children with acute respiratory failure. Prospective, observational study. Single-center tertiary noncardiac PICU in a children's hospital. Invasively ventilated children with acute respiratory failure. Diaphragm thickness at end-expiration and end-inspiration were serially measured by ultrasound in 56 patients (median age, 17 mo; interquartile range, 5.5-52), first within 36 hours of intubation and last preceding extubation. The median duration of mechanical ventilation was 140 hours (interquartile range, 83-201). At initial measurement, thickness at end-expiration was 2.0 mm (interquartile range, 1.8-2.5) and thickness at end-inspiration was 2.5 mm (interquartile range, 2-2.8). The change in thickness at end-expiration during mechanical ventilation between first and last measurement was -13.8% (interquartile range, -27.4% to 0%), with a -3.4% daily atrophy rate (interquartile range, -5.6 to 0%). Thickening fraction = ([thickness at end-inspiration - thickness at end-expiration]/thickness at end-inspiration) throughout the course of mechanical ventilation was linearly correlated with spontaneous breathing fraction (beta coefficient, 9.4; 95% CI, 4.2-14.7; p = 0.001). For children with a period of spontaneous breathing fraction less than 0.5 during mechanical ventilation, those with exposure to a continuous neuromuscular blockade infusion (n = 15) had a significantly larger decrease in thickness at end-expiration compared with children with low spontaneous breathing fraction who were not exposed to a neuromuscular blockade infusion (n = 18) (-16.4%, [interquartile range, -28.4% to -7.0%] vs -7.3%; [interquartile range, -10.9% to -0%]; p = 0.036). Diaphragm atrophy is present in children on mechanical ventilation for acute respiratory failure. Diaphragm contractility, measured as

    Evidence from animal studies suggests that gastrointestinal motility is impaired in acute pancreatitis. Enteral nutrition, and more specifically nasogastric tube feeding, has emerged as a key treatment modality in patients with acute pancreatitis, but its effect on motility has not been investigated in this setting. The aim was to validate the Gastroparesis Cardinal Symptom Index (GCSI) in patients with acute pancreatitis and determine the effect of nasogastric tube feeding on GCSI. The study design was a randomized controlled trial. Patients were allocated to nasogastric tube feeding or nil per os within 24 hours of hospital admission. GCSI data from before randomization to 72 hours after randomization were analyzed. The test-retest reliability analysis was used to calculate Cronbach's α. Seventeen patients were randomized to nasogastric tube feeding and 18 to nil per os. Overall, the total GCSI score significantly decreased over the study (F = 8.537; P = .001) but was not significantly different between the 2 study groups during hospitalization (F = 1.159; P = .322). However, patients on nasogastric tube feeding did show improved appetite compared with nil per os (F = 3.526; P = .036). The GCSI was found to be a reliable tool in the setting of acute pancreatitis (Cronbach's α = 0.852). Nasogastric tube feeding does not appear to affect dysmotility symptoms in acute pancreatitis as measured by the GCSI, although appetite improved. Use of the simple, noninvasive, and inexpensive GCSI tool to evaluate motility is recommended in future clinical trials in pancreatology. © 2015 American Society for Parenteral and Enteral Nutrition.

    In numerous species social learning is predominant and adaptive, yet, we know little of its neurobiological mechanisms. Social learning is modulated by motivations and emotions, in a manner that is often sexually dimorphic. Additionally, stress hormones acutely modulate the related social cognitive process of social recognition. Whether this is true even for social learning is currently unknown. We investigated the acute effects of the stress hormone corticosterone (CORT) on the social transmission of food preferences (STFP) in male and female mice. During a brief social interaction an observer (OBS) acquires a food preference from a same-sex demonstrator (DEM). CORT (1.0, 2.5, 5.0 mg/kg), its ethanol vehicle (0.1%), and saline solution (0.9%) were administered intraperitoneally to the OBS, 10 min before a 30-min social interaction. Levels of plasma CORT were assessed in other mice that had received the same doses of CORT and either had or had not gone through a 30 min social interaction 10 min post-treatment. Exogenous CORT elicited levels of plasma level comparable to those seen at the peak of the circadian cycle and facilitated the STFP with males responding more than females both in terms of the duration of the food preference and the minimum effective dose. CORT also sexually dimorphically inhibited feeding, with females showing a greater dose-response than males. Saline solution and ethanol vehicles also sexually dimorphically facilitated the STFP and reduced feeding, but less than CORT did. These results indicate that CORT facilitates social learning, like social recognition. Hence, CORT may generally increase social information processing. Copyright © 2013 Elsevier Ltd.

    Acute respiratory infections (ARI) are the leading cause of death in young children in Pakistan, responsible for 20-30% of child deaths under age 5 years. This paper summarizes the research and technical development efforts over the last 15 years which have contributed to improving the effectiveness of the case management strategy to reduce mortality from 5' pneumonia in children in Pakistan. Community intervention is viable, effective and practical. Rising antimicrobial resistance among commonly used and A low-cost oral agent is of significant concern. Appropriate monitoring and evaluation of the impact of the ARI control programme is lacking. Lack of funding for programmatic activities, lack of coordination with other child survival programs, inadequate training for community health workers and general practitioners in the private sector, lack of public awareness about seeking timely and appropriate care and insufficient planning and support for ARI in the programmatic activities at provincial and district levels are major hindrances in decreasing the burden of ARI in the country. The recent introduction of the community-based Lady Health Worker (LHW) Programme and WHO and UNICEF-sponsored integrated management of childhood illness initiative present ideal opportunities for re-emphasizing early case detection and appropriate case management of ARI. Ultimately, focusing on preventive strategies such as improving nutrition, reducing indoor pollution, improving mass vaccination, as well as introduction of new vaccines effective against important respiratory pathogens will likely have the most impact on reducing severe ARI and deaths from severe disease.

  7. Rapid progression of diabetic nephropathy is linked to inflammation and episodes of acute renal failure.

    Chronic kidney disease (CKD) from diabetic nephropathy is characterized by progressive loss of renal function. The renal decline has been viewed as a linear fall, presumably dependent on metabolic, hemodynamic and dietary stresses. However, renal injury in diabetic nephropathy can be rapidly aggravated by unpredictable external and internal factors, a state of affairs inconsistent with a linear loss of function. Acute renal injury and subsequent inflammation are potential factors, and we investigated their presence in renal biopsies from patients with nephropathy. In a protocol approved by the Indiana University School of Medicine Institutional Review Board, renal biopsy specimens, estimated GFR, proteinuria and renal survival were examined in patients with diabetic nephropathy. Prominent clusters of inflammatory cells, particularly macrophages, were detected in the renal biopsy specimens. CKD progressed rapidly but not linearly, in that CKD was characterized by a succession of seemingly random episodes of self-limited acute renal failure. Episodes of acute kidney injury were associated with progression to end-stage renal disease. We propose that diabetic nephropathy is complicated by unpredictable and possibly random episodes of usually self-limited acute renal failure, and by subsequent renal inflammation, which appear to accelerate progression and eventual kidney loss.

    Oral feeding intolerance (OFI) is a common complication of acute pancreatitis that leads to prolonged hospitalization, increased use of hospital resources, and impaired quality of life. However, there are no clinically useful predictors of OFI. The aims of this study were to determine whether gastrointestinal dysmotility is associated with the development of OFI, and whether the gastroparesis cardinal symptom index (GCSI) can be used as a predictive tool in a clinical setting. This was a prospective cohort study. The primary outcome was the development of OFI. Daily GCSI total score and subscores (nausea/vomiting, early satiety, and bloating) were recorded. Univariate and multivariate binary logistic regression analyses were conducted, adjusting for age, etiology of pancreatitis, severity, diabetes status, and time from symptom onset to hospital admission. The study included 217 consecutive adult patients with acute pancreatitis. Multivariate analyses showed significant associations between OFI occurrence and the total GCSI score on day 2 of hospital admission (odds ratio [OR], 1.42; 95% confidence interval [CI], 1.02-2.00), the highest total GCSI score (OR, 1.38; 95% CI, 1.03-1.86), the day 2 nausea/vomiting subscore (OR, 1.40; 95% CI, 1.04-1.89), the day 2 bloating subscore (OR, 1.25; 95% CI, 1.01-1.54), and the highest bloating subscore (OR, 1.32; 95% CI, 1.08-1.63). Gastrointestinal dysmotility is associated with the development of OFI and the GCSI has potential as a clinically useful predictive tool in the setting of acute pancreatitis. The developed nomogram holds promise but needs to be validated externally. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available Kayo Kure, Ryo Obata, Yuji Inoue, Aya Iriyama, Yasuo YanagiDepartment of Ophthalmology, University of Tokyo School of Medicine, Tokyo, JapanAbstract: Some patients with acute zonal occult outer retinopathy (AZOOR show symptomatic acute visual impairment in one eye only, but electrophysiological abnormalities in both eyes. A 46-year-old female who had noticed paracentral scotoma of her right eye six months previously was referred to our hospital. At initial examination, her best-corrected visual acuity was 0.7 in the right eye and 1.2 in the left. Whereas the full-field rod electroretinogram (ERG was normal in both eyes, the cone response was nonrecordable in the right eye and showed a significant decrease in amplitude in the left eye. The 30 Hz flicker ERG showed similar results. Multifocal ERG was nonrecordable in the right eye and showed a residual response in only the central part of the left. Fourteen months after the first visit, the patient presented complaining of acute visual acuity loss in the left eye. Visual acuity in her left eye had decreased to 0.01. The multifocal ERG was nonrecordable. Although the patient chose oral prednisolone therapy, only limited recovery was observed in the patient. Even if only the ERG shows changes and there are no other symptoms, ophthalmologists should continue observation in view of the possibility of an acute exacerbation.Keywords: acute zonal occult outer retinopathy, electroretinogram, scotoma

    Tissue distribution of the radionuclides were found in the groups given the chronic exposure. Under chronic exposure to 60 Co, 109 Cd, and 137 Cs, quail rapidly accumulated these radioisotopes and the respective body burden concentrations began to level off after 11, 21, and 21 days of exposure. The biological half-lives for radioisotopes accumulated during the chronic feedings were 13 days for 60 Co, 8 days for 109 Cd, and 11 days for 137 Cs. In contrast, biological half-lives for these radioisotopes under acute feeding conditions (single four-hour feeding) were 15 days for 60 Co, 3 days for 109 Cd, and 10 days for 137 Cs. These results indicate that food chain behavior of 60 Co and 137 Cs in Bobwhite is similar following either acute or chronic exposure to contaminated food. For 109 Cd, biological retention in Bobwhite was longer under chronic exposure conditions. (U.S.)

    To assess the effect of carbohydrate and caffeine on gross efficiency (GE), 14 cyclists (V̇O 2max 57.6 ± 6.3 ml.kg -1. min -1 ) completed 4 × 2-hour tests at a submaximal exercise intensity (60% Maximal Minute Power). Using a randomized, counter-balanced crossover design, participants consumed a standardised diet in the 3-days preceding each test and subsequently ingested either caffeine (CAF), carbohydrate (CHO), caffeine+carbohydrate (CAF+CHO) or water (W) during exercise whilst GE and plasma glucose were assessed at regular intervals (~30 mins). GE progressively decreased in the W condition but, whilst caffeine had no effect, this was significantly attenuated in both trials that involved carbohydrate feedings (W = -1.78 ± 0.31%; CHO = -0.70 ± 0.25%, p = 0.008; CAF+CHO = -0.63 ± 0.27%, p = 0.023; CAF = -1.12 ± 0.24%, p = 0.077). Blood glucose levels were significantly higher in carbohydrate ingestion conditions (CHO = 4.79 ± 0.67 mmol·L -1, p feeding strategy should be carefully monitored prior to and during assessment.

    The viral genotype has been shown to play an important role in HIV pathogenesis following transmission. However, the viral phenotypic properties that contribute to disease progression remain unclear. Most studies have been limited to the evaluation of Gag function in the context of a recombinant virus backbone. Using this approach, important biological information may be lost, making the evaluation of viruses obtained during acute infection, representing the transmitted virus, a more biologically relevant model. Here, we evaluate the roles of viral infectivity and the replication capacity of viruses from acute infection in disease progression in women who seroconverted in the CAPRISA 004 tenofovir microbicide trial. We show that viral replication capacity, but not viral infectivity, correlates with the set point viral load (Spearman r = 0.346; P = 0.045) and that replication capacity (hazard ratio [HR] = 4.52; P = 0.01) can predict CD4 decline independently of the viral load (HR = 2.9; P = 0.004) or protective HLA alleles (HR = 0.61; P = 0.36). We further demonstrate that Gag-Pro is not the main driver of this association, suggesting that additional properties of the transmitted virus play a role in disease progression. Finally, we find that although viruses from the tenofovir arm were 2-fold less infectious, they replicated at rates similar to those of viruses from the placebo arm. This indicates that the use of tenofovir gel did not select for viral variants with higher replication capacity. Overall, this study supports a strong influence of the replication capacity in acute infection on disease progression, potentially driven by interaction of multiple genes rather than a dominant role of the major structural gene gag IMPORTANCE HIV disease progression is known to differ between individuals, and defining which fraction of this variation can be attributed to the virus is important both clinically and epidemiologically. In this study, we show that the replication

    Full Text Available Viral infections are an important cause of pediatric Acute Respiratory Distress Syndrome (ARDS. Numerous viruses, including respiratory syncytial virus (RSV and influenza A (H1N1 virus, have been implicated in the progression of pneumonia to ARDS; yet the incidence of progression is unknown. Despite acute and chronic morbidity associated with respiratory viral infections, particularly in ‘at risk’ populations, treatment options are limited. Thus, with few exceptions, care is symptomatic. In addition, mortality rates for viral related ARDS have yet to be determined. This review outlines what is known about ARDS secondary to viral infections including the epidemiology, the pathophysiology and diagnosis. In addition, emerging treatment options to prevent infection, and to decrease disease burden will be outlined. We focused on RSV and influenza A (H1N1 viral-induced ARDS, as these are the most common viruses leading to pediatric ARDS, and have specific prophylactic and definitive treatment options.

    Telomerase (TERT) is a ribonucleoprotein enzyme that preserves the molecular organization at the ends of eukaryotic chromosomes. Since TERT deregulation is a common step in leukaemia, treatments targeting telomerase might be useful for the therapy of hematologic malignancies. Despite a large spectrum of potential drugs, their bench-to-bedside translation is quite limited, with only a therapeutic vaccine in the clinic and a telomerase inhibitor at late stage of preclinical validation. We recently demonstrated that the adoptive transfer of T cell transduced with an HLA-A2-restricted T-cell receptor (TCR), which recognize human TERT with high avidity, controls human B-cell chronic lymphocytic leukaemia (B-CLL) progression without severe side-effects in humanized mice. In the present report, we show the ability of our approach to limit the progression of more aggressive leukemic pathologies, such as acute myeloid leukaemia (AML) and B-cell acute lymphoblastic leukaemia (B-ALL). Together, our findings demonstrate that TERT-based adoptive cell therapy is a concrete platform of T cell-mediated immunotherapy for leukaemia treatment.

    Ultraspatially resolved synchrotron radiation based infrared microspectroscopy is able to detect the structure features of a food or feed tissue at cellular and molecular levels. However, to date, this advanced synchrotron-based technique is almost unknown to food and feed scientists. The objective of this article was to introduce this novel analytical technology, ultra-spatially resolved synchrotron radiation based infrared microspectroscopy (SR-IMS) to food, feed, conventional nutrition, and molecular nutrition scientists. The emphasis of this review focused on the following areas: (1) Principles of molecular spectroscopy for food and feed structure research, such as protein molecular structure, carbohydrate conformation, heating induced protein structure changes, and effect of gene-transformation on food and feed structure; (2) Molecular spectral analysis methodology; (3) Biological applications of synchrotron SR-IMS and DRIFT spectroscopy; and (4) Recent progress in food, feed and nutrition research program. The information described in this article gives better insight in food structure research progress and update.

    The putative role of the gut in amplification of systemic inflammation in acute pancreatitis is gaining credence, and intraluminal nutrition has been shown to decrease inflammation in experimental models of pancreatitis. Prepyloric feeding often is used in people with acute pancreatitis, but has not been evaluated in dogs. Early intervention with enteral nutrition (EN) delivered proximal to the pylorus will be well tolerated in dogs with acute pancreatitis and provide justification for further larger trials. Ten dogs with severe acute pancreatitis in an open-label, prospective pilot study. Dogs were treated with plasma transfusion and standard care, and then consecutively assigned to receive either EN via esophagostomy tube feeding or parenteral nutrition (PN). Outcome was used to determine optimal study size for future studies, and complications were compared between the 2 groups. A significantly greater number of vomiting or regurgitating episodes occurred in dogs receiving PN. The dogs receiving EN did not demonstrate any noticeable postprandial pain. There were more catheter-related complications in the PN group. There was no difference in outcome between the 2 treatments, and 43 dogs for each treatment would be required in future studies to determine a difference in outcome. Early EN delivered proximal to the pylorus is well tolerated in dogs with severe pancreatitis and resulted in fewer complications than PN. Prospective trials in a larger cohort are justified to fully establish the potential benefit of early EN, preferably compared with minimal enteral nutrition.

    Proposed modifications to the National Oil and Hazardous Substance Pollution Contingency Plan have prompted examinations of the methodology used in toxicity testing of the water soluble fraction (WSF) of oil, commercial bioremediation agents (CBA), and a combination of the two. The organisms currently used in acute (96 hr) testing of these agents are the inland silverside, Menidia beryllina, and an estuarine mysid, Mysidopsis bahia. The mysid is a carnivorous species that must be fed during a test in order to prevent predation within the test chambers. Currently proposed methodology for silverside testing also includes feeding. The high oxygen demand of CBAs and the WSF of oil causes dissolved oxygen to be a factor in toxicity. This effect can be intensified by the addition of brine shrimp (Artemia sp.) to the test chambers. The purpose of this study was to compare the toxicity of CBAs in combination with the WSF of oil to silversides with and without the addition of food. Tests were conducted using both 24-hour and 14-day spinning times for the CBA/WSF mixture. With the 24-hour spinning time, LC50 values from each day of the 4-day test were consistently lower in the Artemia fed test (47.8--22.6%) as compared to the unfed test (72.1--43.0%). A similar trend was seen in the 24 and 48 hour LC50's in the 14-day spinning time. Overall, low dissolved oxygen was found to be most relevant at the highest CBA/WSF concentrations where D.O. dropped below 2 mg/l in Artemia fed tests

    Full Text Available Objective: This study investigated the chronic (oral and acute (hypothalamic infusion effects of L-arginine supplementation on feed intake, body composition, and behavioral changes in rats. Methods: Twenty rats were divided into two groups treated orally for 60 days; one group received L-arginine (1 g/kg body weight and one group received saline (1 mL/NaCl 0.9%. Daily consumption of water and food were evaluated, and weight monitored. After the oral treatment, the rats underwent stereotactic biopsy and a group was injected with 2 µL of L-arginine (0.5 mM and another received an injection of saline (0.9% NaCl, in the hypothalamic route, through micro infusion. Immediately after micro infusion, the animal behavior was evaluated through tests in the open field. Food and water consumption were evaluated at 12 and 24 hours after the micro infusion. Daily water consumption and weight gain evolution were evaluated. At the end of treatments, rats were euthanized and blood was collected for glucose, glycerol, and cholesterol evaluation, and histological analysis of vital organs. Results: Oral supplementation with L-arginine increased water intake (11%, p<0.05 and promoted weight gain (3%, p<0.05. However, hypothalamic infusion promoted a significant increase in chow intake (30%, p<0.05 after 24 hours of L-arginine administration. Conclusion: Chronic oral treatment with L-arginine was not effective on appetite modulation; however, an effect was observed when L-arginine was administered directly into the hypothalamus, suggesting a central regulation on appetite through nNOS sensitization. Chronic use of L-arginine did not cause substantial changes in anthropometric, biochemical, behavioral, or histological variables.

    Full Text Available The current study evaluates the impact of high saturated fat feeding in rat model of experimental nephrotoxicity induced by gentamicin. Sprague-Dawley rats weighing 200 g were randomized into four groups; the first one received the standard rodents chow for 8 weeks and was treated as control, the second group (HFDreceived an experimental high fat diet rich in palm kernel oil (40% of Calories as fat for the same period. The third group (HFDG was given 80 mg/kg (body weight/day gentamicin sulphate intraperitoneally during the last 24 days of the feeding period while the fourth group was given gentamicin as above along with the standard rodents chow. Renal function was assessed through measuring serum creatinine, creatinine clearance and absolute and fractional excretion of both sodium and potassium. At the end, rats underwent a surgical procedure for blood pressure measurement. Renal function study showed a stronger nephrotoxicity for HFDG group. Hypertension was observed in HFD group while the pressure declined after gentamicin co-administration. Overall, changing the feeding behavior toward using more SAFFAs for rats injected with gentamicin promotes the progression of renal failure.

    Magnetic resonance imaging detects blood-brain barrier disruption after gadolinium-DTPA enhancement of central nervous system lesions of multiple sclerosis. Experimental allergic encephalomyelitis has many clinical and pathological features in common with multiple sclerosis including alterations in the integrity of the blood-brain barrier. We have compared T2-weighted cranial MR images with Gd-DTPA dimeglumine-enhanced T1-weighted images of myelin basic protein-induced acute (Days 8-42 postimmunization) and central nervous system-induced chronic-progressive (Days 70-95 postimmunization) forms of experimental allergic encephalomyelitis in the guinea pig. Although animals from both groups had abnormal T2-weighted images, only the myelin basic protein-acute-EAE animals (Days 14-24 postimmunization) showed enhancement on postcontrast MR studies. The different responses of the acute and chronic diseases may result from different immunogens, severity of disease, or different permeability of the blood-brain barrier. Therefore, gadolinium-DTPA-enhanced, T1-weighted MR images distinguish acutely active and chronic inflammatory lesions in experimental allergic encephalomyelitis.

    Full Text Available Objective To investigate the MRI abnormalities and acute madopar responsiveness test in diagnosing progressive supranuclear palsy (PSP and Parkinson's disease (PD. Methods Seventeen patients with PSP and 17 gender and age matched patients with PD were studied with cranial MRI examinations and results of acute madopar responsiveness test, and the clinical manifestations of PSP were summarized. Results The atrophy of the midbrain tegmentum and hummingbird sign was demonstrated in all of the PSP patients in our study, but was not observed in the PD patients. The areas of the midbrain on mid-sagittal MRI in PSP patients [(77.35 ± 15.30 mm2] were significantly smaller than that in those with PD [(142.35 ± 31.49 mm2]. The average ratio of the area of the midbrain to the area of pons in the patients with PSP [(14.31 ± 2.47%] was significantly smaller than that in those with PD [(24.08 ± 4.73%; P = 0.000, for all]. According to the result of acute madopar responsiveness test, the maximum Unified Parkinson's Disease Rating Scale (UPDRS Ⅲ improvement rate of 2 patients with PSP and 16 patients with PD was more than 30% (χ2 = 23.142, P = 0.000. Conclusion The assessment of the mid-sagittal MRI and acute madopar responsiveness test may be a useful method to differentiate PSP from PD.

    With the extensive application of cellular and molecular genetic techniques in the research of acute leukemia (AL), the diagnosis of AL type has been developed from FAB typing which was based on morphological classification in 1976 to MICM typing in 2001. This progress highlights the importance of cellular and molecular genetic changes in the diagnosis of leukemia. The cellular and molecular genetic abnormalities in acute leukemia can make the stratification of risk and give the guidance for prognosis and treatment, which is also critical for the development of new drugs. This article has focused on chromosomal abnormalities, fusion gene expression and their relationship with the leukemia diagnosis, prognosis and treatment. This article is also a concise review on several common gene mutations in cytogenetics of ANLL for the assessment of disease prognosis. In recent years, further exploration of molecular cytogenetic mechanisms of various types of leukemia in ANLL contributed to the development of new therapeutic strategy for leukemia.

    Full Text Available BACKGROUND: Early diagnosis is vital to HIV control. γδ T cells play critical roles in viral infections, but their activation in acute HIV infected patients and follow up to 18 months has not been described. METHODS: Changes in γδ T cells, including subsets, function and activation, in treated and untreated acutely HIV-infected patients (n = 79 were compared by cytotoxicity assay and flow cytometry with healthy controls (n = 21 at month 0, 6, 12 and 18. RESULTS: In acutely HIV-infected patients, Vδ1 cell proportion was elevated (P = 0.027 with Vδ2 population reduced (P = 0.002. Effector and central memory γδ T cell factions were decreased (P = 0.006 and P = 0.001, respectively, while proportion of terminal γδ T cells increased (P = 0.002. γδ T cell cytotoxicity was compromised over time. Fraction of IL-17-producing cells increased (P = 0.008, and IFN-γ-producing cells were unaffected (P = 0.115. Elevation of a microbial translocation marker, sCD14, was associated with γδ T cell activation (P = 0.001, which increased in a time-dependent manner, correlating with CD4/CD8 T cell activation set-points and CD4 counts. Antiretroviral therapy did not affect these changes. CONCLUSIONS: γδ T cell subpopulation and functions change significantly in acute HIV infection and over time. Early γδ T cell activation was associated with CD4/CD8 T cell activation set-points, which predict AIDS progression. Therefore, γδ T cell activation represents a potential surrogate marker of AIDS progression.

    F-18 fluoromisonidazole (FMISO) PET has been known to image viable hypoxic area. We performed this study to define whether FMISO PET can reveal ischemic penumbra of acute ischemic stroke. We prospectively selected acute ischemic stroke patients with large diffusion-perfusion mismatch due to occlusion of MCA or ICA on MRI among patients who visited emergency room within 24 hours after stroke onset. FMISO PET and diffusion weighted MR image (DWI) performed within 48 hours after initial MRI. We excluded the patients who performed any reperfusion procedure. To define the final infarcted area, DWI was performed again 2 days after PET scan. Brain FMISO PET was performed 3 hour after the injection of FMISO (370 MBq). FMISO PET was assessed by visual and quantitative analysis. The extent of abnormally increased FMISO uptake was automatically calculated by the number and size of voxels having higher count than upper 3SD of the mean count of contralateral normal hemisphere. We compared the extent of abnormal FMISO uptake area with the change of the extent of ischemic lesions on DWI. Fifteen patients were enrolled in this study. Ten of these patients showed abnormally increased FMISO uptake in peri-infarct area. Ischemic lesion size on follow-up DWI significantly increased in all patients with abnormally increased FMISO uptake except one patient of whom the MCA spontaneously recanalized on follow up angiogram. Ischemic lesions on DWI increased in only one of five patients without abnormally increased FMISO uptake. The extent of abnormally increased FMISO uptake area was positively correlated with infarct size progression on DWI (Spearman correlation coefficient = 0.757, p<0.01). FMISO uptake specifically and sensitively predicted early lesion progression in acute ischemic stroke patients with large diffusion-perfusion mismatch. Therefore, FMISO PET will be a good indicator of the revascularization or reperfusion procedure for acute ischemic stroke by defining ischemic

    The cytokine interferon-gamma (IFNgamma) is implicated in the induction of acute CNS inflammation, but it is less clear what role if any IFNgamma plays in progression to chronic demyelination and neurological deficit. To address this issue, we have expressed IFNgamma in myelinating oligodendrocyt....... IFNgamma therefore may play a role in chronic demyelination and long-term disability following the induction of demyelinating disease. Because IFNgamma may have neural as well as immune-infiltrating origins, these findings generate a new perspective on its role in the CNS....

    In the present paper, the authors review the progress of researches on the mechanism of acupuncture therapy underlying improvement of acute cerebral hemorrhage from experimental studies and research methods. The effects of acupuncture intervention mainly involve (1) lessening inflammatory reactions, (2) reducing impairment of free radicals and excitatory amino acids on cerebral neurons, (3) balancing release of vascular bioactive substances to increase regional cerebral blood flow, and (4) promoting repair and regeneration of the neural tissue, etc. In regard to the research methods, many new biological techniques such as biological molecular approaches, neuro-cellular chemical methods, reverse transcription-polymerase chain reaction (RT-PCR) or quantitative real time-PCR, situ hybridization, western blotting, electron microscope, etc., have been extensively applied to researches on the underlying mechanism of acupuncture therapy for cerebral infarction. In addition, the authors also pointed out that in spite of achieving some bigger progresses in experimental studies, most of the results basically reflect static, isolated and regional changes rather than dynamic and whole body changes. For this reason, more vivo research techniques and noninvasive research methods are highly recommended to be used in the future research on the underlying mechanisms of acupuncture therapy for acute cerebral ischemia.

The main aim of this study was to assess the progress in their implementation using scientometric analysis. The following scientometric indices were used: 1 popularity index, representing the share of articles on a specific technique (or a drug relative to all articles in the field of acute pain; 2 index of change, representing the degree of growth in publications on a topic compared to the previous period; and 3 index of expectations, representing the ratio of the number of articles on a topic in the top 20 journals relative to the number of articles in all (>5,000 biomedical journals covered by PubMed. Publications on specific topics (ten techniques and 21 drugs were assessed during four time periods (1993–1997, 1998–2002, 2003–2007, and 2008–2012. In addition, to determine whether the status of routine acute pain management has improved over the past 20 years, we analyzed surveys designed to be representative of the national population that reflected direct responses of patients reporting pain scores. By the 2008–2012 period, popularity index had reached a substantial level (≥5% only with techniques or drugs that were introduced 30–50 years ago or more (epidural analgesia, patient-controlled analgesia, nerve blocks, epidural analgesia for labor or delivery, bupivacaine, and acetaminophen. In 2008–2012, promising (although modest changes of index of change and index of expectations were found only with dexamethasone. Six national surveys conducted for the past 20 years demonstrated an unacceptably high percentage of patients experiencing moderate or severe pain with not even a trend toward outcome improvement.

    To analyze the characteristics of children with acute viral bronchiolitis subjected to mechanical ventilation for three consecutive years and to correlate their progression with mechanical ventilation parameters and fluid balance. Longitudinal study of a series of infants (mechanical ventilation for acute viral bronchitis from January 2012 to September 2014 in the pediatric intensive care unit. The children's clinical records were reviewed, and their anthropometric data, mechanical ventilation parameters, fluid balance, clinical progression, and major complications were recorded. Sixty-six infants (3.0 ± 2.0 months old and with an average weight of 4.7 ± 1.4kg) were included, of whom 62% were boys; a virus was identified in 86%. The average duration of mechanical ventilation was 6.5 ± 2.9 days, and the average length of stay in the pediatric intensive care unit was 9.1 ± 3.5 days; the mortality rate was 1.5% (1/66). The peak inspiratory pressure remained at 30cmH2O during the first four days of mechanical ventilation and then decreased before extubation (25 cmH2O; p mechanical ventilation day four was 402 ± 254mL, which corresponds to an increase of 9.0 ± 5.9% in body weight. Thirty-seven patients (56%) exhibited a weight gain of 10% or more, which was not significantly associated with the ventilation parameters on mechanical ventilation day four, extubation failure, duration of mechanical ventilation or length of stay in the pediatric intensive care unit. The rate of mechanical ventilation for acute viral bronchiolitis remains constant, being associated with low mortality, few adverse effects, and positive cumulative fluid balance during the first days. Better fluid control might reduce the duration of mechanical ventilation.

    Full Text Available Patients with a hip fracture lose more than 50% knee-extension strength in the fractured limb within one week of surgery. Hence, immediate progressive strength training following hip fracture surgery may be rational, but the feasibility unknown.To examine the feasibility of in-hospital progressive strength training implemented in the acute ward following hip fracture surgery, based on pre-specified criteria for feasibility.A prospective cohort study conducted in an acute orthopedic hip fracture unit at a university hospital.

    The natural history of the progression from acute spontaneous urticaria (ASU) to chronic spontaneous urticaria (CSU), CSU remains poorly understood. To identify clinical and laboratory patient attributes that may be predictive of ASU progression to CSU. We prospectively studied consecutive adult patients (age ≥ 18 years) with a diagnosis of urticaria of urticaria activity score assessment were performed in all the patients at baseline and then at weeks 7, 12, 24, and 48. Of 114 patients with acute urticaria and without identifiable causes, 73 patients (64%) were included in the ASU group, 41 patients in the CSU group (36%), and 44 healthy subjects in the control group. At baseline, 26 patients in the CSU group (63.4%) had a positive ASST result, whereas only 17 patients with a positive ASST result (23.3%) were revealed in the ASU group (p < 0.001). Patients with baseline ASST positive results were characterized by more profound basopenia (mean [standard deviation], 0.05 ± 0.08 cell/mm(3)) and more anti-thyroid peroxidase antibodies (18 [41.8%]) than those with the negative baseline ASST result (mean [standard deviation], 0.13 ± 0.09 cell/mm(3), p < 0.001 more profound basopenia; and 13 (18.1%), p = 0.009 more thyroid peroxidase antibodies). We observed the disappearance of ASST positive result in some patients with CSU with baseline positive ASST results, whereas, in some subjects with CSU, baseline negative ASST results came to be positive results throughout the study period. A baseline positive ASST result of patients with ASU was a significant determinant (odds ratio 5.91 [95% confidence interval, 2.57-13.62]; p < 0.001) for a CSU diagnosis at week 7. The patients with ASU who progressed toward CSU were characterized by a positive ASST result, thyroid autoimmunity, and profound basopenia at baseline.

    Osteoporotic compression spine fractures have a different clinical course and outcomes when compared to spinal fractures occurring in the younger population. Only a few studies have investigated the risk factors for progressive osteoporotic compression spine fractures. The purpose of this study was to investigate clinical and radiological factors related to progressive collapse following acute osteoporotic compression spine fractures. We retrospectively identified all patients treated for thoracolumbar fractures in our institution between January 2008 and July 2013. Included cases were examined by plain radiographs and CT scans. For each patient we classified the fracture according to the AOSpine Thoracolumbar Spine Injury Classification System. The difference between initial and final height loss and initial and final local kyphosis was documented as height loss difference and kyphotic angle difference. The presence of old fractures and intravertebral cleft were also documented. The study included 153 patients, comprising 102 women and 51 men. The mean patient age was 68.9years. The mean length of follow up was 15months. A statistically significant correlation was found between patient age, final height loss, height loss difference and kyphotic angle difference. Height loss difference and kyphotic angle difference were significantly correlated to type of fracture according to the AO classification system. The height loss difference was 18.1% in A1 type fractures, 27.1% in A2 type fractures, 24.2% in A3 type fractures and 25.7% in A4 type fractures. During a minimum 3-month follow up of conservative treatment for acute osteoporotic vertebral compression fractures, age and the AOSpine Thoracolumbar Spine Injury Classification System were predictive factors for progressive collapse.

    Insulin has been shown to stimulate leptin mRNA expression acutely in rat adipose tissue, but its short-term effects on circulating leptin levels, and subsequent feeding behavior, have not been well described. We used 11-mo-old female selectively bred obesity-resistant (OR) and obesity-prone (OP) Sprague-Dawley rats maintained on laboratory chow to investigate this question. At testing, body weights and basal leptin levels of the OP rats were significantly elevated compared with the OR rats. In the 3-h fasted state, injection of 2.0 U insulin/kg ip resulted in significant elevations of plasma leptin at 4 h postinjection in both OP and OR groups (hour 4, +2.50 and +5.98 ng/ml, respectively). In separate feeding tests with the same groups, intake of laboratory chow pellets was significantly inhibited during hours 2-4 after 2.0 U/kg of insulin in the OR (-80.1%, P < 0.05), but not in the OP group, compared with intake after saline injections. In feeding tests with palatable moderately high-fat pellets after 2.0 and 3.0 U insulin/kg ip, significant decreases between hours 2 and 4 in intake were seen in the OR group only (-41.0 and -68.3%, respectively). Thus feeding inhibition coincides with insulin-induced elevations of plasma leptin in lean but not obese Sprague-Dawley rats. Our data suggest that elevations of leptin within the physiological range may contribute to short-term inhibition of food intake in rats and that this process may be stimulated by feeding-related insulin release.

    Intrachromosomal amplification of chromosome 21 is a heterogeneous chromosomal rearrangement occurring in 2% of cases of childhood precursor B-cell acute lymphoblastic leukemia. These abnormalities are too complex to engineer faithfully in animal models and are unrepresented in leukemia cell lines. As a resource for future functional and preclinical studies, we have created xenografts from the leukemic blasts of patients with intrachromosomal amplification of chromosome 21 and characterized them by in-vivo and ex-vivo luminescent imaging, flow immunophenotyping, and histological and ultrastructural analyses of bone marrow and the central nervous system. Investigation of up to three generations of xenografts revealed phenotypic evolution, branching genomic architecture and, compared with other B-cell acute lymphoblastic leukemia genetic subtypes, greater clonal diversity of leukemia-initiating cells. In support of intrachromosomal amplification of chromosome 21 as a primary genetic abnormality, it was always retained through generations of xenografts, although we also observed the first example of structural evolution of this rearrangement. Clonal segregation in xenografts revealed convergent evolution of different secondary genomic abnormalities implicating several known tumor suppressor genes and a region, containing the B-cell adaptor, PIK3AP1, and nuclear receptor co-repressor, LCOR, in the progression of B-cell acute lymphoblastic leukemia. Tracking of mutations in patients and derived xenografts provided evidence for co-operation between abnormalities activating the RAS pathway in B-cell acute lymphoblastic leukemia and for their aggressive clonal expansion in the xeno-environment. Bi-allelic loss of the CDKN2A/B locus was recurrently maintained or emergent in xenografts and also strongly selected as RNA sequencing demonstrated a complete absence of reads for genes associated with the deletions.

    2002-07-01

    Incentive schemes for the development of renewable energy sources may focus on quantities (defining national targets and setting up bidding systems, or quota systems providing for green certificate trading), or they may focus on prices (feed-in tariffs). Whatever the system chosen, the role of the public authorities is quite specific: to stimulate technical progress and speed up the technological learning processes so that ultimately renewable energy technologies will be able to compete with conventional technologies, once the environmental costs have been internalized. A comparison of instruments must thus take into account the characteristics of the innovation process and adoption conditions (uncertainties regarding cost curves, learning effects) which means also looking at dynamic efficiency criteria. The paper concludes that a system of feed-in tariffs is more efficient than a bidding system, but highlights the theoretical interest of green certificate trading which must be confirmed through practice, given the influence of market structures and rules on the performance of this type of approach.

    Study on the action mechanism of inflammatory mediators generated by the severe acute pancreatitis (SAP) in multiple organ injury is a hotspot in the surgical field. In clinical practice, the main complicated organ dysfunctions are shock, respiratory failure, renal failure, encephalopathy, with the rate of hepatic diseases being closely next to them. The hepatic injury caused by SAP cannot only aggravate the state of pancreatitis, but also develop into hepatic failure and cause patient death. Its complicated pathogenic mechanism is an obstacle in clinical treatment. Among many pathogenic factors, the changes of vasoactive substances, participation of inflammatory mediators as well as OFR (oxygen free radical), endotoxin, etc. may play important roles in its progression.

    POMC-derived melanocortins inhibit food intake. In the adult rodent brain, POMC-expressing neurons are located in the arcuate nucleus (ARC) and the nucleus tractus solitarius (NTS), but it remains unclear how POMC neurons in these two brain nuclei regulate feeding behavior and metabolism differentially. Using pharmacogenetic methods to activate or deplete neuron groups in separate brain areas, in the present study, we show that POMC neurons in the ARC and NTS suppress feeding behavior at different time scales. Neurons were activated using the DREADD (designer receptors exclusively activated by designer drugs) method. The evolved human M3-muscarinic receptor was expressed in a selective population of POMC neurons by stereotaxic infusion of Cre-recombinase-dependent, adeno-associated virus vectors into the ARC or NTS of POMC-Cre mice. After injection of the human M3-muscarinic receptor ligand clozapine-N-oxide (1 mg/kg, i.p.), acute activation of NTS POMC neurons produced an immediate inhibition of feeding behavior. In contrast, chronic stimulation was required for ARC POMC neurons to suppress food intake. Using adeno-associated virus delivery of the diphtheria toxin receptor gene, we found that diphtheria toxin-induced ablation of POMC neurons in the ARC but not the NTS, increased food intake, reduced energy expenditure, and ultimately resulted in obesity and metabolic and endocrine disorders. Our results reveal different behavioral functions of POMC neurons in the ARC and NTS, suggesting that POMC neurons regulate feeding and energy homeostasis by integrating long-term adiposity signals from the hypothalamus and short-term satiety signals from the brainstem.

    Wound healing consists of three overlapping phases: inflammation, proliferation, and matrix synthesis and remodeling. Prolonged alcohol abuse can cause liver fibrosis due to deregulated matrix remodeling. Previous studies demonstrated that moderate ethanol feeding enhances liver fibrogenic markers and frank fibrosis independent of differences in CCl₄-induced liver injury. Our objective was to determine whether or not other phases of the hepatic wound healing response were affected by moderate ethanol after CCl₄ exposure. Mice were fed moderate ethanol (2% v/v) for two days and then were exposed to CCl₄ and euthanized 24-96 h later. Liver injury was not different between pair- and ethanol-fed mice; however, removal of necrotic tissue was delayed after CCl₄-induced liver injury in ethanol-fed mice. Inflammation, measured by TNFα mRNA and protein and hepatic Ly6c transcript accumulation, was reduced and associated with enhanced hepatocyte apoptosis after ethanol feeding. Hepatocytes entered the cell cycle equivalently in pair- and ethanol-fed mice after CCl₄ exposure, but hepatocyte proliferation was prolonged in livers from ethanol-fed mice. CCl₄-induced hepatic stellate cell activation was increased and matrix remodeling was prolonged in ethanol-fed mice compared to controls. Taken together, moderate ethanol affected each phase of the wound healing response to CCl₄. These data highlight previously unknown effects of moderate ethanol exposure on hepatic wound healing after acute hepatotoxicant exposure.

    The aim of this study was to investigate the presence of various atypical pneumonia agents (Chlamydia pneumoniae, cytomegalovirus, Mycoplasma pneumoniae), which are considered to have a role in the ethiopathogenesis of atherosclerosis, in aortic biopsies without macroscopically visible plaque and in internal thoracic artery biopsies. Thirty-three patients (group 1), who had undergone coronary bypass operation and 10 non-atherosclerotic patients (group 2), were included in the study. Seventy-six tissue biopsies were taken. Biopsies from the patients in group 1 a were obtained from the atheroma plaque-free aortic tissue and 33 biopsies (group Ib) were obtained from their internal thoracic arteries. Following DNA extraction, nested PCR was used to detect Chlamydia pneumoniae DNA, and real time PCR was used to detect cytomegalovirus and Mycoplasma pneumoniae DNA. Blood parameters (lipid profile, CRP, fibrinogen) of the patients and operation characteristics were recorded. Chlamydia pneumoniae DNA was detected in 5 of 33 biopsy samples from coronary bypass patients, whereas none of the control patients (group 1b and group 2) were positive for this agent (P = 0.001). Neither CMV nor Mycoplasma pneumoniae was detected in IMA and aortic biopsies of both bypass and control patients. Elevated total cholesterol levels (P = 0.02) and positive CRP (P = 0.001) was found in C. pneumoniae positive patients. Prevalence of acute coronary syndrome was significantly higher in C. pneumoniae detected patients compared (P = 0.00 1). Detection of C. pneumoniae DNA in the atheroma free aortic biopsies might indicate that this micro-organism intervened in the progression of atheroma plaque. There was a strong relationship between the detection of this micro-organism in the aortic wall and acute coronary syndrome. The absence of DNA of the corresponding micro-organisms in the IMA wall may show its resistance to infective agents and in turn to atherosclerosis, which is a result of the

    Consumption of fruits and vegetables has been implicated in lowering net acid excretion (NAE), but few studies have directly examined NAE and urinary calcium effects. Further, there is no evidence that only fresh fruits and vegetables must be consumed for a beneficial effect on bone. A crossover, acute-load study was designed to investigate whether processed fruit was as effective as fresh fruit in reducing NAE and protein-induced hypercalciuria. Fifteen women completed three dietary treatments on three different mornings. A fasting urine sample was collected before consuming one of the following three isocaloric high-protein treatments: control, fresh apples, and processed applesauce. The serving size for the applesauce treatment was 2.5 times that for fresh apples. Urine was collected at baseline (0 h) and at 1.5, 3.0, and 4.5 h. Compared with baseline, NAE increased after control treatment but decreased after fresh or processed apple treatment (P = 0.041). Calcium excretion increased with all treatments by 3 h; however, the increase was less for fresh apple and applesauce (P = 0.024). In an acute feeding model, fruit intake reduced NAE and urinary calcium excretion. Processed fruit appears to be effective, although a larger serving size was needed than with fresh fruit.

    Since progressive hemorrhagic injury (PHI) was introduced in neurosurgical literatures, several studies have been performed, the results of which have influenced doctors but do not define guidelines for the best treatment of PHI. PHI may be confirmed by a serial computerized tomography (CT) scan, and it has been shown to be associated with a fivefold increase in the risk of clinical worsening and is a significant cause of morbidity and mortality as well. So, early detection of PHI is practically important in a clinical situation. To analyze the early CT signs of progressive hemorrhagic injury following acute traumatic brain injury (TBI) and explore their clinical significances, PHI was confirmed by comparing the first and repeated CT scans. Data were analyzed and compared including times from injury to the first CT and signs of the early CT scan. Logistic regression analysis was used to show the risk factors related to PHI. A cohort of 630 TBI patients was evaluated, and there were 189 (30%) patients who suffered from PHI. For patients with their first CT scan obtained as early as 2 h post-injury, there were 116 (77.25%) cases who suffered from PHI. The differences between PHIs and non-PHIs were significant in the initial CT scans showing fracture, subarachnoid hemorrhage (SAH), brain contusion, epidural hematoma (EDH), subdural hematoma (SDH), and multiple hematoma as well as the times from injury to the first CT scan (P < 0.01). Logistic regression analysis showed that early CT scans (EDH, SDH, SAH, fracture, and brain contusion) were predictors of PHI (P < 0.01). For patients with the first CT scan obtained as early as 2 h post-injury, a follow-up CT scan should be performed promptly. If the initial CT scan shows SAH, brain contusion, and primary hematoma with brain swelling, an earlier and dynamic CT scan should be performed for detection of PHI as early as possible and the medical intervention would be enforced in time.

    Acute respiratory distress syndrome (ARDS) represents the ultimate pulmonary response to a wide range of injuries, from septicemia to trauma. Optimal nutrition is vital to enhancing oxygen delivery, supporting adequate cardiac contractility and respiratory musculature, eliminating fluid and electrolyte imbalances, and supporting the proinflammatory response. Research is providing a better understanding of nutrients that specifically address the complex physiologic changes in ARDS. This article highlights the pathophysiology of ARDS as it relates to nutrition, relevant nutritional assessment, and important enteral and parenteral considerations for the pediatric patient who has ARDS.

    The aim of this study was to describe the proportion of acute respiratory compromise events in hospitalized pediatric patients progressing to cardiopulmonary arrest, and the clinical factors associated with progression of acute respiratory compromise to cardiopulmonary arrest. We hypothesized that failure of invasive airway placement on the first attempt (defined as multiple attempts at tracheal intubation, and/or laryngeal mask airway placement, and/or the creation of a new tracheostomy or cricothyrotomy) is independently associated with progression of acute respiratory compromise to cardiopulmonary arrest. Multicenter, international registry of pediatric in-hospital acute respiratory compromise. American Heart Association's Get with the Guidelines-Resuscitation registry (2000-2014). Children younger than 18 years with an index (first) acute respiratory compromise event. None. Of the 2,210 index acute respiratory compromise events, 64% required controlled ventilation, 26% had return of spontaneous ventilation, and 10% progressed to cardiopulmonary arrest. There were 762 acute respiratory compromise events (34%) that did not require an invasive airway, 1,185 acute respiratory compromise events (54%) with successful invasive airway placement on the first attempt, and 263 acute respiratory compromise events (12%) with failure of invasive airway placement on the first attempt. After adjusting for confounding variables, failure of invasive airway placement on the first attempt was independently associated with progression of acute respiratory compromise to cardiopulmonary arrest (adjusted odds ratio 1.8 [95% CIs, 1.2-2.6]). More than 1 in 10 hospitalized pediatric patients who experienced an acute respiratory compromise event progressed to cardiopulmonary arrest. Failure of invasive airway placement on the first attempt is independently associated with progression of acute respiratory compromise to cardiopulmonary arrest.

    Acute pancreatitis in pregnancy is not a frequent condition: only a few hundred cases have been published in the literature. Its diagnosis can be misguided by clinical manifestations of the pregnancy itself, and by the delay in ordering the required diagnostic tests. These facts may contribute to the serious prognosis of this disease, which in the past had a mortality of up to 20%. The treatment recommended is conservative. A surgical intervention in the event of biliary lithiasis is best to be postponed till after delivery. Parenteral alimentation can be helpful because of its effects in the promotion of pancreatic rest with simultaneous improvement of the nutritional conditions of the mother and the fetus.

    One hundred twenty-eight nonmalnourished male patients between 3 and 36 months of age were randomly assigned to receive one of four lactose-free dietary treatments to determine the effect of dietary therapy on the severity and nutritional outcome of diarrheal illness. Group 1 received a formula diet composed of casein, sucrose, dextrin with maltose (Dextri-Maltose), and vegetable oil to provide 110 kcal/kg body weight/d (CSO-110). Group 2 received CSO to provide 55 kcal/kg/d (CSO-55) for 2 days and then CSO-110. Group 3 received only oral glucose-electrolyte solution (GES) for 2 days, CSO-55 for the next 2 days, and then CSO-110. Group 4 received the same diets as Group 3 except that only intravenous GES was used for the first 2 days. The GES maintenance solutions provided 24 to 30 kcal/kg/d. Therapeutic success rates were similar among dietary groups, ranging from 90% to 97%. Fecal excretion was initially lower in group 4 (P less than 0.05) but was similar initially among groups treated orally and among all four groups beginning on day 3. Net apparent absorption of nitrogen, fat, carbohydrate, and total energy; retention of nitrogen; and increments in body weight, arm circumference, and skin-fold thickness were positively related to the amounts of dietary energy consumed. Thus continued oral feeding with the CSO diets during the early phase of therapy yielded improved nutritional results.

    Full Text Available Optimal timing of ART initiation for individuals presenting with AIDS-related OIs has not been defined.A5164 was a randomized strategy trial of "early ART"--given within 14 days of starting acute OI treatment versus "deferred ART"--given after acute OI treatment is completed. Randomization was stratified by presenting OI and entry CD4 count. The primary week 48 endpoint was 3-level ordered categorical variable: 1. Death/AIDS progression; 2. No progression with incomplete viral suppression (ie HIV viral load (VL >or=50 copies/ml; 3. No progression with optimal viral suppression (ie HIV VL <50 copies/ml. Secondary endpoints included: AIDS progression/death; plasma HIV RNA and CD4 responses and safety parameters including IRIS. 282 subjects were evaluable; 141 per arm. Entry OIs included Pneumocytis jirovecii pneumonia 63%, cryptococcal meningitis 12%, and bacterial infections 12%. The early and deferred arms started ART a median of 12 and 45 days after start of OI treatment, respectively. THE DIFFERENCE IN THE PRIMARY ENDPOINT DID NOT REACH STATISTICAL SIGNIFICANCE: AIDS progression/death was seen in 20 (14% vs. 34 (24%; whereas no progression but with incomplete viral suppression was seen in 54 (38% vs. 44 (31%; and no progression with optimal viral suppression in 67 (48% vs 63 (45% in the early vs. deferred arm, respectively (p = 0.22. However, the early ART arm had fewer AIDS progression/deaths (OR = 0.51; 95% CI = 0.27-0.94 and a longer time to AIDS progression/death (stratified HR = 0.53; 95% CI = 0.30-0.92. The early ART had shorter time to achieving a CD4 count above 50 cells/mL (p<0.001 and no increase in adverse events.Early ART resulted in less AIDS progression/death with no increase in adverse events or loss of virologic response compared to deferred ART. These results support the early initiation of ART in patients presenting with acute AIDS-related OIs, absent major contraindications.ClinicalTrials.gov NCT00055120.

    The World Heart Federation criteria for the echocardiographic diagnosis of rheumatic heart disease (RHD) include a category "Borderline" RHD which may represent the earliest evidence of RHD. We aimed to determine the significance of minor heart valve abnormalities, including Borderline RHD, in predicting the future risk of acute rheumatic fever (ARF) or RHD. A prospective cohort study of Aboriginal and Torres Strait Islander children aged 8 to 18 years was conducted. Cases comprised children with Borderline RHD or other minor non-specific valvular abnormalities (NSVAs) detected on prior echocardiography. Controls were children with a prior normal echocardiogram. Participants underwent a follow-up echocardiogram 2.5 to 5 years later to assess for progression of valvular changes and development of Definite RHD. Interval diagnoses of ARF were ascertained. There were 442 participants. Cases with Borderline RHD were at significantly greater risk of ARF (incidence rate ratio 8.8, 95% CI 1.4-53.8) and any echocardiographic progression of valve lesions (relative risk 8.19, 95% CI 2.43-27.53) than their Matched Controls. Cases with Borderline RHD were at increased risk of progression to Definite RHD (1 in 6 progressed) as were Cases with NSVAs (1 in 10 progressed). Children with Borderline RHD had an increased risk of ARF, progression of valvular lesions, and development of Definite RHD. These findings provide support for considering secondary antibiotic prophylaxis or ongoing surveillance echocardiography in high-risk children with Borderline RHD.

    Patients with acute liver failure (ALF) often die of intracranial pressure (IP) and cerebral herniation. Main contributors to increased IP are ammonia, glutamine, edema, and blood flow. The sequence of events and underlying mechanisms, as well as the temporal pattern, regional distribution, and contribution of each parameter to the progression of neurologic deterioration and IP, are unclear. We studied rats with ALF to follow the progression of changes in ammonia, glutamine, grade and type (vasogenic or cytotoxic) of edema, blood-brain barrier permeability, cerebral blood flow, and IP. We assessed whether the changes in these parameters were similar between frontal cortex and cerebellum and evaluated the presence, type, and progression of edema in 12 brain areas. ALF was induced by injection of galactosamine. The grade and type of edema was assessed by measuring the apparent diffusion coefficient by magnetic resonance imaging. Cerebral blood flow was measured by magnetic resonance and blood-brain barrier permeability by Evans blue-albumin extravasation. Increased IP arises from an early increase of blood-brain barrier permeability in certain areas (including cerebellum but not frontal cortex) followed by vasogenic edema. Ammonia and glutamine then increase progressively, leading to cytotoxic edema in many areas. Alterations in lactate and cerebral blood flow are later events that further increase IP. Different mechanisms in specific regions of the brain contribute, with different temporal patterns, to the progression of cerebral alterations and IP in ALF. Copyright © 2011 AGA Institute.

Physical exam revealed right sided abdominal tenderness with associated mass. All laboratory values were within normal ranges. Both abdominal ultrasound and computed tomography of the abdomen/pelvis revealed a large distended gallbladder with wall thickening and gallstones. Based on presentation and radiologic findings, the emergency general surgery service was consulted for suspected acute cholecystitis. The patient was then admitted for intravenous antibiotics and scheduled for laparoscopic cholecystectomy the following day. Intra-operative findings revealed volvulus with acute necrosis of the entire gallbladder. The gallbladder had a long pedunculated cystic duct and artery that was detorsed before proceeding with resection. Postoperatively, the patient did well and was discharged a few days later tolerating a regular diet

    The Japanese Guidelines for management of acute cholangitis and cholecystitis were published in 2005 as the first practical guidelines presenting diagnostic and severity assessment criteria for these diseases. After the Japanese version, the Tokyo Guidelines (TG07) were reported in 2007 as the first international practical guidelines. There were some differences between the two guidelines, and some weak points in TG07 were pointed out, such as low sensitivity for diagnosis and the presence of divergence between severity assessment and clinical judgment for acute cholangitis. Therefore, revisions were started to not only make them up to date but also concurrent with the same diagnostic and severity assessment criteria. The Revision Committee for the revision of TG07 (TGRC) performed validation studies of TG07 and new diagnostic and severity assessment criteria of acute cholangitis and cholecystitis. These were retrospective multi-institutional studies that collected cases of acute cholangitis, cholecystitis, and non-inflammatory biliary disease. TGRC held 35 meetings as well as international email exchanges with co-authors abroad and held three International Meetings. Through these efforts, TG13 improved the diagnostic sensitivity for acute cholangitis and cholecystitis, and presented criteria with extremely low false positive rates. Furthermore, severity assessment criteria adapted for clinical use, flowcharts, and many new diagnostic and therapeutic modalities were presented. The world's first management bundles of acute cholangitis and cholecystitis were also presented. The revised Japanese version was published with the same content as TG13. An electronic application of TG13 that can help to diagnose and assess the severity of these diseases using the criteria of TG13 was made for free download.

    Full Text Available Acute-on-chronic liver failure (ACLF is a clinical entity encompassing an acute deterioration of liver function and failure of one or more organs, which results in high short-term mortality rate. In recent years, a number of novel prognostic markers of ACLF have emerged and provided a basis for the treatment and prognostic evaluation of ACLF. Researches on both commonly used and novel makers for prognosis of ACLF are reviewed in order to improve the existing prognostic evaluation system and to provide a basis for the treatment and prognostic evaluation of ACLF.

    2015-10-01

    Functional elucidation of the endogenous opioid system temporally paralleled the creation and growth of the journal, Peptides, under the leadership of its founding editor, Dr. Abba Kastin. He was prescient in publishing annual and uninterrupted reviews on Endogenous Opiates and Behavior that served as a microcosm for the journal under his stewardship. This author published a 2004 review, "Endogenous opioids and feeding behavior: a thirty-year historical perspective", summarizing research in this field between 1974 and 2003. The present review "closes the circle" by reviewing the last 10 years (2004-2014) of research examining the role of endogenous opioids and feeding behavior. The review summarizes effects upon ingestive behavior following administration of opioid receptor agonists, in opioid receptor knockout animals, following administration of general opioid receptor antagonists, following administration of selective mu, delta, kappa and ORL-1 receptor antagonists, and evaluating opioid peptide and opioid receptor changes in different food intake models.

  5. Minimal Residual Disease in Acute Myeloid Leukemia: Still a Work in Progress?

    Directory of Open Access Journals (Sweden)

    Federico Mosna

    2017-06-01

    Full Text Available Minimal residual disease evaluation refers to a series of molecular and immunophenotypical techniques aimed at detecting submicroscopic disease after therapy. As such, its application in acute myeloid leukemia has greatly increased our ability to quantify treatment response, and to determine the chemosensitivity of the disease, as the final product of the drug schedule, dose intensity, biodistribution, and the pharmakogenetic profile of the patient. There is now consistent evidence for the prognostic power of minimal residual disease evaluation in acute myeloid leukemia, which is complementary to the baseline prognostic assessment of the disease. The focus for its use is therefore shifting to individualize treatment based on a deeper evaluation of chemosensitivity and residual tumor burden. In this review, we will summarize the results of the major clinical studies evaluating minimal residual disease in acute myeloid leukemia in adults in recent years and address the technical and practical issues still hampering the spread of these techniques outside controlled clinical trials. We will also briefly speculate on future developments and offer our point of view, and a word of caution, on the present use of minimal residual disease measurements in “real-life” practice. Still, as final standardization and diffusion of the methods are sorted out, we believe that minimal residual disease will soon become the new standard for evaluating response in the treatment of acute myeloid leukemia.

  6. Further progress is needed in procedures for the biological evaluation of dietary protein quality in pig and poultry feeds

    2017-08-01

    Full Text Available Recently, biological procedures for feed protein evaluation in pig and poultry diets have been based on the amino acid composition of feed ingredients considering the animal's losses during processes of digestion or total protein utilization in a different manner. Such a development towards individual amino acids (AAs was inevitable according to the disadvantage of traditional protein quality measures, like biological value (BV or net protein utilization (NPU, to be non-additive in complex animal diets. In consequence, such measures are generally not suitable for predicting the final protein quality of protein mixtures from the individual protein value of feed ingredients. Otherwise, recent measures of AA disappearance from the small intestine up to the end of the ileum (ileal AA digestibility also do not provide a true reflection of the biological availability of individual feed AAs independent of the extent of taking into account endogenous AA losses during digestion processes. Sophisticated procedures for protein evaluation are needed considering the AA losses, both during absorption and utilization after absorption. Advantages and limitations of important developments in procedures are discussed. Accordingly, the development of an exponential modelling approach is described (the Göttingen approach, which overcomes some of the traditional disadvantages by measuring the individual AA efficiency. Connecting feed protein evaluation, the modelling of quantitative AA requirements, and improved ideal protein concepts offers different fields of application. In addition, as demonstrated by example, the modelling of nitrogen losses per unit protein deposition and the minimizing of this parameter yields a further interesting tool for lowering the nitrogen burden from protein utilization processes. Finally, it is pointed out that traditional laboratory procedures also need to be updated, adapted to current knowledge, and validated according to the

    2017-08-01

    Full Text Available The article describes a clinical case of multiple myeloma in 78-year-old man, its clinical onset was as an acute attack of gout. The patient was admitted to hospital due to the development of the first acute attack of gout. The attack was characterized by polyarthricular joint lesion of the upper and lower extremities, pronounced inflammatory reaction, insufficient response to the use of non-steroidal anti-inflammatory drugs, and a high level of hyperuricemia. The serum uric acid concentration ranged from 636 to 712 μmol/l. The study of the synovial fluid of the inflamed knee joint made it possible to reveal uric acid crystals and to confirm the diagnosis of acute gouty arthritis. Simultaneously, the patient had significant renal impairment: creatinine was 574 μmol/l, urea — 39.9 mmol/l, glomerular filtration rate according to CKD-EPI — 8 ml/min. The daily proteinuria was 1.8 g. A retrospective assessment of laboratory parameters allowed to reveal completely normal indicators of renal function 6 months ago. Considering the development of acute gouty arthritis, its polyarticular nature, persistent course, rapid involvement of new joints, high uric acid levels during an acute attack exceeding 600 μmol/l (10 mg/dL, rapid development of renal failure within 6 months until the terminal stage, it was suggested the secondary nature of gout on the background of kidney damage by another pathological process. Further clinical, laboratory and instrumental studies allowed verifying multiple myeloma with renal damage. Bence Jones protein in the urine was not detected, there was also no evidence of hyperproteinemia. However, pain in the spine, ribs and chest was the basis for carrying out an X-ray study of the bones of the skeleton. Changes in the skeleton typical for multiple myeloma have been identified. Myelogram showed a high content of plasma cells (21.1 %, electrophoresis of blood proteins showed a high M-gradient (30.42 %, and a cytochemical

    Full text: The value of the abdominal radiograph in the assessment of the acute abdomen was evaluated for those patients who also had abdominal ultrasound and/or CT. The value of each modality in patient management is reviewed. Retrospective review of 52 consecutive patients presented to a tertiary hospital emergency department with acute abdominal pain who underwent abdominal radiographs (AXR) and abdominal ultrasound (US) and / or computed tomography (CT) within 24 hours of presentation was undertaken. There were 37 males and 15 females. The mean age was 53 years (range 18-95y). Abdominal radiographs were reviewed by two radiologists.Two patients had two separate admissions one week apart. There were 35 normal abdominal radiographs. 19 studies showed clinically relevant abnormalities. Of the normal group, 14 out of 21 patients had abnormal findings on CT and 8 out of 16 had abnormal US examinations. Of the 19 patients with abnormal AXR, 17 out of 19 patients had abnormal CT and 2 out of 5 had abnormal ultrasound examinations. There were 5 cases where both CT scan and US was performed. The positive and negative predictive value for AXR vs CT scan was 89% and 33% respectively and for AXR vs US scan was 40% and 50% respectively. For patients with normal AXR and abnormal CT, there was only one case (a non calcified abdominal aortic aneurysm) which might have required immediate surgical intervention. The preliminary results suggest that the abnormal radiograph is sensitive in the detection of relevant abnormalities in the acute abdomen in the context of appropriate clinical selection. Both CT and ultrasound provide additional diagnostic accuracy for some indications.A further 50 patients are being reviewed and the combined results will be presented.

    'The objective is to reduce the volume and cost of high-level waste glass produced during US DOE remediation activities by demonstrating that magnetic separation can separate crystalline, amorphous, and colloidal constituents in vitrification feed streams known to be deleterious to the production of borosilicate glass. Magnetic separation will add neither chemicals nor generate secondary waste streams. The project includes the systematic study of magnetic interactions of waste constituents under controlled physical and chemical conditions (e.g., hydration, oxidation, temperature) to identify mechanisms that control the magnetic properties. Partitioning of radionuclides to determine their sorption mechanisms is also being studied. The identification of fundamental magnetic properties within the microscopic chemical environment in combination with hydrodynamic and electrodynamic models provides insights into the design of a system for optimal separation. Following this, experimental studies using superconducting open-gradient magnetic separation (OGMS) will be conducted to validate its effectiveness as a pretreatment technique.'

  13. Dopaminergic modulation of effort-related choice behavior as assessed by a progressive ratio chow feeding choice task: pharmacological studies and the role of individual differences.

    Directory of Open Access Journals (Sweden)

    Patrick A Randall

    Full Text Available Mesolimbic dopamine (DA is involved in behavioral activation and effort-related processes. Rats with impaired DA transmission reallocate their instrumental behavior away from food-reinforced tasks with high response requirements, and instead select less effortful food-seeking behaviors. In the present study, the effects of several drug treatments were assessed using a progressive ratio (PROG/chow feeding concurrent choice task. With this task, rats can lever press on a PROG schedule reinforced by a preferred high-carbohydrate food pellet, or alternatively approach and consume the less-preferred but concurrently available laboratory chow. Rats pass through each ratio level 15 times, after which the ratio requirement is incremented by one additional response. The DA D(2 antagonist haloperidol (0.025-0.1 mg/kg reduced number of lever presses and highest ratio achieved but did not reduce chow intake. In contrast, the adenosine A(2A antagonist MSX-3 increased lever presses and highest ratio achieved, but decreased chow consumption. The cannabinoid CB1 inverse agonist and putative appetite suppressant AM251 decreased lever presses, highest ratio achieved, and chow intake; this effect was similar to that produced by pre-feeding. Furthermore, DA-related signal transduction activity (pDARPP-32(Thr34 expression was greater in nucleus accumbens core of high responders (rats with high lever pressing output compared to low responders. Thus, the effects of DA antagonism differed greatly from those produced by pre-feeding or reduced CB1 transmission, and it appears unlikely that haloperidol reduces PROG responding because of a general reduction in primary food motivation or the unconditioned reinforcing properties of food. Furthermore, accumbens core signal transduction activity is related to individual differences in work output.

    Mesolimbic dopamine (DA) is involved in behavioral activation and effort-related processes. Rats with impaired DA transmission reallocate their instrumental behavior away from food-reinforced tasks with high response requirements, and instead select less effortful food-seeking behaviors. In the present study, the effects of several drug treatments were assessed using a progressive ratio (PROG)/chow feeding concurrent choice task. With this task, rats can lever press on a PROG schedule reinforced by a preferred high-carbohydrate food pellet, or alternatively approach and consume the less-preferred but concurrently available laboratory chow. Rats pass through each ratio level 15 times, after which the ratio requirement is incremented by one additional response. The DA D(2) antagonist haloperidol (0.025-0.1 mg/kg) reduced number of lever presses and highest ratio achieved but did not reduce chow intake. In contrast, the adenosine A(2A) antagonist MSX-3 increased lever presses and highest ratio achieved, but decreased chow consumption. The cannabinoid CB1 inverse agonist and putative appetite suppressant AM251 decreased lever presses, highest ratio achieved, and chow intake; this effect was similar to that produced by pre-feeding. Furthermore, DA-related signal transduction activity (pDARPP-32(Thr34) expression) was greater in nucleus accumbens core of high responders (rats with high lever pressing output) compared to low responders.

    Diseases of adulthood, such as diabetes and hypertension, may be related to changes during pregnancy, particularly in kidney. We hypothesized that acute kidney injury progresses more rapidly in cases of fetal programming. Diabetic dams' offspring were divided into: CC (controls, receiving vehicle); DC (diabetics, receiving vehicle); CA (controls receiving folic Acid solution, 250 mg/kg); and DA (diabetics receiving folic acid solution). Renal function tests, morphometry, gene, and protein expression of epithelial-mesenchymal transition (EMT) markers were analyzed by qPCR and immunohistochemistry, respectively. Creatinine, urea, Bowman's space, and EMT markers were increased in CA and DA groups. TGF-β3, actin, and fibronectin expression was higher in CA and DA, with significant increase in DA compared to CA 2-mo offspring. There was higher expression level of TGF-β1, TGF-β3, fibronectin, and vimentin in the offspring of diabetic dams at 5 mo. Increases in TGF-β1 and TGF-β3 were more evident in the offspring of diabetic dams. Fetal programming promotes remarkable changes in kidney morphology, and function in offspring and renal failure progression may be faster in younger offspring of diabetic dams subjected to an additional injury.

    Pediatric oncology, notably childhood acute lymphoblastic leukemia (ALL), is currently one of the health-leading concerns worldwide and a biomedical priority. Decreasing overall leukemia mortality in children requires a comprehensive understanding of its pathobiology. It is becoming clear that malignant cell-to-niche intercommunication and microenvironmental signals that control early cell fate decisions are critical for tumor progression. We show here that the mesenchymal stromal cell component of ALL bone marrow (BM) differ from its normal counterpart in a number of functional properties and may have a key role during leukemic development. A decreased proliferation potential, contrasting with the strong ability of producing pro-inflammatory cytokines and an aberrantly loss of CXCL12 and SCF, suggest that leukemic lymphoid niches in ALL BM are unique and may exclude normal hematopoiesis. Cell competence ex vivo assays within tridimensional coculture structures indicated a growth advantage of leukemic precursor cells and their niche remodeling ability by CXCL12 reduction, resulting in leukemic cell progression at the expense of normal niche-associated lymphopoiesis.

    α-Klotho is highly expressed in the kidney, and its extracellular domain is cleaved and released into the circulation. Chronic kidney disease (CKD) is a state of α-Klotho deficiency, which exerts multiple negative systemic effects on numerous organs including the cardiovascular system. Since acute kidney injury (AKI) greatly escalates the risk of CKD development, we explored the effect of α-Klotho on prevention and treatment on post-AKI to CKD progression and cardiovascular disease. Therein, ischemia reperfusion injury-induced AKI was followed by early administration of recombinant α-Klotho or vehicle starting one day and continued for four days after kidney injury (CKD prevention protocol). A CKD model was generated by unilateral nephrectomy plus contralateral ischemia reperfusion injury. Late administration of α-Klotho in this model was started four weeks after injury and sustained for 12 weeks (CKD treatment protocol). The prevention protocol precluded AKI to CKD progression and protected the heart from cardiac remodeling in the post-AKI model. One important effect of exogenous α-Klotho therapy was the restoration of endogenous α-Klotho levels long after the cessation of exogenous α-Klotho therapy. The treatment protocol still effectively improved renal function and attenuated cardiac remodeling in CKD, although these parameters did not completely return to normal. In addition, α-Klotho administration also attenuated high phosphate diet-induced renal and cardiac fibrosis, and improved renal and cardiac function in the absence of pre-existing renal disease. Thus, recombinant α-Klotho protein is safe and efficacious, and might be a promising prophylactic or therapeutic option for prevention or retardation of AKI-to-CKD progression and uremic cardiomyopathy.

    We report a case of a 66-year-old woman with progressing myelopathy. Her history revealed instrumented fusion from T10 to S1 for degenerative lumbar kyphosis and spinal stenosis. The plain radiographs showed narrowing of the intervertebral disc space with a gas shadow and sclerotic end-plate changes at T9-T10. Magnetic resonance imaging revealed a posterolateral mass compressing the spinal cord at the T9-T10 level. The patient was treated with a discectomy through the posterior approach combined with posterior instrumentation. The patient's symptoms and myelopathy resolved completely after the discectomy and instrumented fusion. The thoracic disc herniation might have been caused by the increased motion and stress concentration at the adjacent segment. PMID:20622956

    A scaled up and integrated outpatient therapeutic feeding programme (OTP) brings the treatment of severely malnourished children closer to the community. This study assessed recovery from severe acute malnutrition (SAM), fatality, and acute malnutrition up to 14 weeks after admission to a programme integrated in the primary health care system. In this cohort study, 1,048 children admitted to 94 OTPs in Southern Ethiopia were followed for 14 weeks. Independent anthropometric measurements and information on treatment outcome were collected at four home visits. Only 32.7% (248/759) of children with SAM on admission fulfilled the programme recovery criteria at the time of discharge (i.e., gained 15% in weight, or oedema, if present at admission, was resolved at discharge). Of all children admitted to the programme for whom nutritional assessment was done 14 weeks later, 34.6% (321/928) were severely malnourished, and 37.5% (348/928) were moderately malnourished; thus, 72.1% were acutely malnourished. Of the children, 27/982 (2.7%) had died by 14 weeks, of whom all but one had SAM on admission. Children with severe oedema on admission had the highest fatality rate (12.0%, 9/75). The median length of admission to the programme was 6.6 weeks (interquartile range: 5.3, 8.4 weeks). Despite children participating for the recommended duration of the programme, many children with SAM were discharged still acutely malnourished and without reaching programme criteria for recovery. For better outcome of OTP, constraints in service provision by the health system as well as challenges of service utilization by the beneficiaries should be identified and addressed. © 2017 The Authors.

    Problems related to feeding behavior in horses fall into three main categories: underconsumption, overconsumption, and abnormal consumption. Anorexia may be caused by a variety of diseases and overcome by removing the underlying causes (pain, fever), and physical or chemical stimulation of appetite. "Hypophagia" may be caused by poor dentition, disease, or stress. Again, removal of the cause or stimulation by physical or chemical means may improve intakes. Acute and chronic overconsumption of feeds are reflections of the normal controls (or lack thereof) of feeding in the horse. The only reliable prevention is to limit access to feeds. Abnormal eating behaviors such as pica or coprophagy are usually caused by a dietary imbalance or boredom. Coprophagey, however, is a normal behavior in young foals. Drinking disorders are rare, the only common one being the avoidance of "strange" water. Masking water at home with specific flavors such as peppermint or vinegar may encourage the horse to drink water from other sources to which the "home" flavor has been added.

    Full Text Available The current study evaluates the impact of high fructose feeding in rat model of gentamicin induced nephrotoxicity. Sprague-Dawley rats weighing 180–200 g were randomized into four groups; (C received standard rodents chow with free access to ad libitum drinking water for 8 weeks and was considered as control, (F received standard rodents chow with free access to drinking water supplemented with 20% (W/V fructose for the same abovementioned period, (FG was fed as group F and was given 80 mg/kg (body weight/day gentamicin sulphate intraperitoneally during the last 20 days of the feeding period, and (G was given gentamicin as above and fed as group C. Renal function was assessed at the end of the treatment period through measuring serum creatinine, uric acid and albumin, creatinine clearance, absolute and fractional excretion of both sodium and potassium, twenty-four-hour urinary excretion of albumin, and renal histology. For metabolic syndrome assessment, fasting plasma glucose and insulin were measured and oral glucose tolerance test was performed throughout the treatment period. Results showed that gentamicin enhances progression of fructose induced metabolic syndrome. On the other hand, fructose pretreatment before gentamicin injection produced a comparable degree of renal dysfunction to those which were given fructose-free water but the picture of nephrotoxicity was somewhat altered as it was characterized by higher extent of glomerular congestion and protein urea. Overall, more vigilance is required when nephrotoxic drugs are prescribed for patients with fructose induced metabolic syndrome.

    Highlights: • Ethanol administration increased GPD1 mRNA expression. • Ethanol administration increased glucose incorporation into TG glycerol moieties. • No increase in hepatic TG levels was observed in ethanol-injected GPD1 null mice. • We propose that GPD1 is required for ethanol-induced TG accumulation in the liver. - Abstract: Acute ethanol consumption leads to the accumulation of triglycerides (TGs) in hepatocytes. The increase in lipogenesis and reduction of fatty acid oxidation are implicated as the mechanisms underlying ethanol-induced hepatic TG accumulation. Although glycerol-3-phosphate (Gro3P), formed by glycerol kinase (GYK) or glycerol-3-phosphate dehydrogenase 1 (GPD1), is also required for TG synthesis, the roles of GYK and GPD1 have been the subject of some debate. In this study, we examine (1) the expression of genes involved in Gro3P production in the liver of C57BL/6J mice in the context of hepatic TG accumulation after acute ethanol intake, and (2) the role of GPD1 in the progression of ethanol-induced fatty liver using GPD1 null mice. As a result, in C57BL/6J mice, ethanol-induced hepatic TG accumulation began within 2 h and was 1.7-fold greater than that observed in the control group after 6 h. The up-regulation of GPD1 began 2 h after administering ethanol, and significantly increased 6 h later with the concomitant escalation in the glycolytic gene expression. The incorporation of {sup 14}C-labelled glucose into TG glycerol moieties increased during the same period. On the other hand, in GPD1 null mice carrying normal GYK activity, no significant increase in hepatic TG level was observed after acute ethanol intake. In conclusion, GPD1 and glycolytic gene expression is up-regulated by ethanol, and GPD1-mediated incorporation of glucose into TG glycerol moieties together with increased lipogenesis, is suggested to play an important role in ethanol-induced hepatic TG accumulation.

    Full Text Available The genetic events associated with transformation of myeloproliferative neoplasms (MPNs to secondary acute myeloid leukemia (sAML, particularly in the subgroup of essential thrombocythemia (ET patients, remain incompletely understood. Deep studies using high-throughput methods might lead to a better understanding of genetic landscape of ET patients who transformed to sAML. We performed array-based comparative genomic hybridization (aCGH and whole exome sequencing (WES to analyze paired samples from ET and sAML phases. We investigated five patients with previous history of MPN, which four had initial diagnosis of ET (one case harboring JAK2 p.Val617Phe and the remaining three CALR type II p.Lys385fs*47, and one was diagnosed with MPN/myelodysplastic syndrome with thrombocytosis (SF3B1 p.Lys700Glu. All were homogeneously treated with hydroxyurea, but subsequently transformed to sAML (mean time of 6 years/median of 4 years to transformation. Two of them have chromosomal abnormalities, and both acquire 2p gain and 5q deletion at sAML stage. The molecular mechanisms associated with leukemic progression in MPN patients are not clear. Our WES data showed TP53 alterations recurrently observed as mutations (missense and frameshift and monoallelic loss. On the other hand, aCGH showed novel chromosome abnormalities (+2p and del5q potentially associated with disease progression. The results reported here add valuable information to the still fragmented molecular basis of ET to sAML evolution. Further studies are necessary to identify minimal deleted/amplified region and genes relevant to sAML transformation.

    Full Text Available Progression of HIV infection is variable among individuals, and definition disease progression biomarkers is still needed. Here, we aimed to categorize the predictive potential of several variables using feature selection methods and decision trees. A total of seventy-five treatment-naïve subjects were enrolled during acute/early HIV infection. CD4+ T-cell counts (CD4TC and viral load (VL levels were determined at enrollment and for one year. Immune activation, HIV-specific immune response, Human Leukocyte Antigen (HLA and C-C chemokine receptor type 5 (CCR5 genotypes, and plasma levels of 39 cytokines were determined. Data were analyzed by machine learning and non-parametric methods. Variable hierarchization was performed by Weka correlation-based feature selection and J48 decision tree. Plasma interleukin (IL-10, interferon gamma-induced protein (IP-10, soluble IL-2 receptor alpha (sIL-2Rα and tumor necrosis factor alpha (TNF-α levels correlated directly with baseline VL, whereas IL-2, TNF-α, fibroblast growth factor (FGF-2 and macrophage inflammatory protein (MIP-1β correlated directly with CD4+ T-cell activation (p < 0.05. However, none of these cytokines had good predictive values to distinguish “progressors” from “non-progressors”. Similarly, immune activation, HIV-specific immune responses and HLA/CCR5 genotypes had low discrimination power. Baseline CD4TC was the most potent discerning variable with a cut-off of 438 cells/μL (accuracy = 0.93, κ-Cohen = 0.85. Limited discerning power of the other factors might be related to frequency, variability and/or sampling time. Future studies based on decision trees to identify biomarkers of post-treatment control are warrantied.

    Full Text Available Objectives: To determine the 2-year outcome of acute kidney injury (AKI following admission to pediatric critical care units (PICU. Methods: A retrospective cohort study was conducted between January 2012 and December 2013. We followed 131 children admitted to PICU, King Abdulaziz University Hospital, Jeddah, Kingdom of Saudi Arabia with a diagnosis of AKI, based on pRIFLE (pediatric risk, injury, failure, loss, and end-stage renal disease, for 2 years. During the study period, 46 children died and 38 of survivors completed the follow-up. Factors affecting long-term progression to chronic kidney disease were also evaluated. Results: The 2-year mortality was more than 40%. The main determinant of the 2-year mortality was the pediatric risk of mortality (PRISM score, which increased the risk of mortality by 6% per each one score (adjusted odds ratio, 1.06: 95% confidence interval: 1.00-1.11. By the end of the 2 years, 33% of survivors had reduction in the glomerular filtration rate and proteinuria, and 73% were hypertensive. Patients with more severe renal impairment at admission, based on the pRIFLE criteria, had higher mortality rate. This association, however, was not independent since it was influenced by baseline disease severity (PRISM score. Conclusion: Large proportion of patients admitted to PICU with AKI either died during the first 2 months of follow-up or developed long-term complications. The severity of AKI, however, was not an independent risk factor for mortality.

    Full Text Available The rotifer Brachionus sp. is commonly used for larval feeding in marine fish hatcheries. The aim of this study was to evaluate whether the inclusion of Acartia tonsa nauplii in the initial diet of carapeva larvae improves their survival, growth and resistance to stress when compared to the regimen containing only rotifers. Adult copepods were collected in the wild and cultured with the microalgae Chaetoceros muelleri, Isochrysis galbana and Nannochloropsis oculata to obtain nauplii. Carapeva larvae were grown for 15 days using four treatments and three replicates: 1 Brachionus plicatilis rotifers (10 to 15/mL; 2 A. tonsa nauplii (0.25 to 0.5/mL; 3 Brachionus plicatilis rotifers (5 to 7.5/mL + A. tonsa nauplii (0.12 to 0.25/mL, and 4 no supply of live feed. After 15 days, the carapeva larvae were subjected to stress by exposure to air for 10 seconds and then returned to the source tank to evaluate survival after 24 h. Survival and stress resistance were higher in carapeva larvae fed B. plicatilis + A. tonsa nauplii (P<0.05, 20.9 ± 11.2% and 88.9%, respectively. These results confirm the positive effect of the inclusion of copepod nauplii in the diet of fish larvae. However, more research is needed to validate these results.

MethodsThe clinical, demographic, treatment and outcome data of 180 ACLF patients with concomitant CHB managed in our hospital between June 2009 and September 2012 were retrospectively reviewed. Clinical data, taken at baseline, included markers of inflammation/infection (white blood cell (WBC count, coagulation (prothrombin time (PT and prothrombin activity (PTA, and liver function (alanine aminotransferase (ALT, aspartate aminotransferase (AST, total bilirubin (TBil, direct bilirubin (DBil, choninesterase (CHE, albumin (Alb, globulin (Glb, total cholesterol (TC, and ammonia. In-hospital treatments included supplementation with traditional Chinese medicine-based therapies, such as Tuihuang decoction and detoxification enema. The primary outcome was survival during hospitalization. The patients were grouped for analysis according to ACLF stage (early, n=93; mid, n=61; late, n=26 and the risk factors associated with each stage were identified by using univariate (log-rank test and multivariate (Cox’s test regression analyses. The association of risk factors with patient survival was assessed by Kaplan-Meier curve analysis. ResultsThe three ACLF groups showed significantly different amounts of leukocytes, with the late ACLF group showing the highest WBC. The late ACLF group also showed significantly lower Glb and TC. There was a trend in reduced cumulative survival rate and shorter time to death that significantly corresponded to progressive stages of ACLF (early ACLF>mid ACLF>late ACLF; all P<0.001.

    The value of perfusion MRI for identifying the tissue at risk has been questioned. Our objective was to assess baseline perfusion-weighted imaging parameters within infarct progression areas. Patients with anterior circulation stroke without early reperfusion were included from a prospective MRI database. Sequential MRI examinations were performed on admission, 2-3 h (H2), 2-3 days (D2), and between 15 and 30 days after the initial MRI. Maps of baseline time-to-peak (TTP), mean transit time (MTT), cerebral blood volume (CBV), and cerebral blood flow (CBF) were calculated. Lesion extension areas were defined as pixels showing de novo lesions between each MRI and were generated by subtracting successive lesion masks: V{sub 0}, baseline diffusion-weighted imaging (DWI) lesion; V{sub 1}, lesion extension between baseline and H2 DWI; V{sub 2}, lesion extension from H2 to D2 DWI; and V{sub 3}, lesion extension from D2 DWI to final FLAIR. Repeated measures analysis was used to compare hemodynamic parameters within the baseline diffusion lesion and subsequent lesion extension areas. Thirty-two patients were included. Baseline perfusion parameters were significantly more impaired within the acute DWI lesion compared to lesion extension areas (TTP, p<0.0001; MTT, p<0.0001; CBF p<0.0001; CBV, p<0.0001). A significant decrease in MTT (p = 0.01) and TTP (p = 0.01) was found within successive lesion growth areas. A decreasing gradient of severity for TTP and MTT was observed within successive infarct growth areas. (orig.)

    To determine the 2-year outcome of acute kidney injury (AKI) following admission to pediatric critical care units (PICU). Methods: A retrospective cohort study was conducted between January 2012 and December 2013. We followed 131 children admitted to PICU, King Abdulaziz University Hospital, Jeddah, Kingdom of Saudi Arabia with a diagnosis of AKI, based on pRIFLE (pediatric risk, injury, failure, loss, and end-stage renal disease), for 2 years. During the study period, 46 children died and 38 of survivors completed the follow-up. Factors affecting long-term progression to chronic kidney disease were also evaluated. Results: The 2-year mortality was more than 40%. The main determinant of the 2-year mortality was the pediatric risk of mortality (PRISM) score, which increased the risk of mortality by 6% per each one score (adjusted odds ratio, 1.06: 95% confidence interval: 1.00-1.11). By the end of the 2 years, 33% of survivors had reduction in the glomerular filtration rate and proteinuria, and 73% were hypertensive. Patients with more severe renal impairment at admission, based on the pRIFLE criteria, had higher mortality rate. This association, however, was not independent since it was influenced by baseline disease severity (PRISM score).  Conclusion: Large proportion of patients admitted to PICU with AKI either died during the first 2 months of follow-up or developed long-term complications. The severity of AKI, however, was not an independent risk factor for mortality.

    The effect of β-glucan as a feed additive on the serum and gene profile of C-reactive protein (CRP) and complement acute phase responses was ascertained in common carp Cyprinus carpio. In addition effects of subsequent intraperitoneal injections of pathogen-associated molecular patterns (PAMPs), i.e. LPS or poly(I:C), to mimic bacterial or viral infection respectively, were studied. Carp were first orally fed with β-glucan (MacroGard®) with a daily β-glucan intake of 6 mg per kg body weight or with control food for 25 days and then injected with PBS containing either LPS (4 mg/kg) or poly(I:C) (5 mg/kg) or PBS alone. Fish were sampled during the 25 days of the feeding period and up to 7 days post-PAMPs injections for serum and liver, head kidney and mid-gut tissues. Oral administration of β-glucan for 25 days significantly increased serum CRP levels and alternative complement activity (ACP). In addition, the subsequent LPS and poly(I:C) challenges significantly affected CRP and complement related gene expression profiles (crp1, crp2, c1r/s, bf/c2, c3 and masp2), with the greatest effects observed in the β-glucan fed fish. However, in fish fed β-glucan the PAMPs injections had less effects on CRP levels and complement activity in the serum than in control fed fish, suggesting that the 25 days of β-glucan immunostimulation was sufficient enough to reduce the effects of LPS and poly(I:C) injections. Results suggest that MacroGard® stimulated CRP and complement responses to PAMPs immunological challenges in common carp thus highlighting the beneficial β-glucan immunostimulant properties.

    Three feeding regimens-centrally produced ready-to-use therapeutic food, locally produced ready-to-use therapeutic food, and augmented, energy-dense, home-prepared food-were provided in a community setting for children with severe acute malnutrition (SAM) in the age group of 6-59 months in an individually randomised multicentre trial that enrolled 906 children. Foods, counselling, feeding support and treatment for mild illnesses were provided until recovery or 16 weeks. Costs were estimated for 371 children enrolled in Delhi in a semiurban location after active survey and identification, enrolment, diagnosis and treatment for mild illnesses, and finally treatment with one of the three regimens, both under the research and government setting. Direct costs were estimated for human resources using a price times quantity approach, based on their salaries and average time taken for each activity. The cost per week per child for food, medicines and other consumables was estimated based on the total expenditure over the period and children covered. Indirect costs for programme management including training, transport, non-consumables, infrastructure and equipment were estimated per week per child based on total expenditures for research study and making suitable adjustments for estimations under government setting. No significant difference in costs was found across the three regimens per covered or per treated child. The average cost per treated child in the government setting was estimated at US$56 (based management of SAM with a locally produced ready-to-use therapeutic food is feasible, acceptable, affordable and very cost-effective in terms of the disability-adjusted life years saved and gross national income per capita of the country. The treatment of SAM at home needs serious attention and integration into the existing health system, along with actions to prevent SAM. NCT01705769; Pre-results.

    Full Text Available Behavioral activation is a fundamental feature of motivation, and organisms frequently make effort-related decisions based upon evaluations of reinforcement value and response costs. Furthermore, people with major depression and other disorders often show anergia, psychomotor retardation, fatigue, and alterations in effort-related decision making. Tasks measuring effort-based decision making can be used as animal models of the motivational symptoms of depression, and the present studies characterized the effort-related effects of the vesicular monoamine transport (VMAT-2 inhibitor tetrabenazine. Tetrabenazine induces depressive symptoms in humans, and also preferentially depletes dopamine (DA. Rats were assessed using a concurrent progressive ratio (PROG/chow feeding task, in which they can either lever press on a PROG schedule for preferred high-carbohydrate food, or approach and consume a less-preferred lab chow that is freely available in the chamber. Previous work has shown that the DA antagonist haloperidol reduced PROG work output on this task, but did not reduce chow intake, effects that differed substantially from those of reinforcer devaluation or appetite suppressant drugs. The present work demonstrated that tetrabenazine produced an effort-related shift in responding on the PROG/chow procedure, reducing lever presses, highest ratio achieved and time spent responding, but not reducing chow intake. Similar effects were produced by administration of the subtype selective DA antagonists ecopipam (D1 and eticlopride (D2, but not by the cannabinoid CB1 receptor neutral antagonist and putative appetite suppressant AM 4413, which suppressed both lever pressing and chow intake. The adenosine A2A antagonist MSX-3, the antidepressant and catecholamine uptake inhibitor bupropion, and the MAO-B inhibitor deprenyl, all reversed the impairments induced by tetrabenazine. This work demonstrates the potential utility of the PROG/chow procedure as a

    Studies performed at space flights and earth-based simulation models detected the plasma indices of acute phase reaction (APR), i.e. the increase of APR cytokine mediators and alterations in the production of blood acute phase proteins (APP) at the initial stages of adaptation to altered gravity conditions. Acute phase response is the principal constituent of the functional activity of innate immunity system. Changes in plasma APPs contents are considered to serve the restoration of homeostasis state. According to trends of their concentration shifts at the evolving of acute phase reaction APPs are denoted as positive, neutral, or negative. Plasma concentrations of positive acute phase proteins α1-acid glycoprotein (α1-AGP), α1-antitrypsin (α1-AT), and neutral α2-macroglobulin (α2-M) were measured in human study at 12-hour antiorthostatic position (AOP) with 15° head down tilt and hypoxia experiments at 14% oxygen in pressure chamber. Both of these impacts were shown to produce alterations in the APP levels indicative for acute phase response. Nevertheless, in AOP experiment noticeable decrease in α1-AGP concentration occurred by hour 12, and even more pronounced decline of α1-AGP and α1-AT were found on hypoxia hours 12 and 36. Acute phase proteins α1-AGP and α2-M possess the features of proteinase inhibitors. This function is implemented by the formation of complexes with the molecules of proteolytic enzymes which subsequently are removed from the blood flow. Transient decrease in plasma concentrations of protease inhibitors on early phases of APR development was reported to result from the growth of plasma protease activity due to cathepsin release from activated leukocytes, which had not yet been compensated by enhanced APP synthesis. Being a carrier protein for positively charged and neutral substances, α1-AGP shows pronounced elevation in its blood content during APR development. As assumed, it is required for the transportation of the increased

    POEMS (polyneuropathy, organomegaly, endocrinopathy, M-protein and skin changes) syndrome is a rare cause of demyelinating neuropathy with monoclonal plasma cell proliferation, and POEMS neuropathy is usually chronically progressive. Herein, the authors report a 34-year-old woman with POEMS syndrome presenting as acute polyneuropathy. Within 2 weeks of disease onset, she became unable to walk with electrodiagnostic features of demyelination and was initially diagnosed as having Guillan-Barré syndrome. Other systemic features (oedema and skin changes) developed later, and an elevated serum level of vascular endothelial growth factor led to the diagnosis of POEMS syndrome. She received high-dose chemotherapy with autologous peripheral blood stem cell transplantation, resulting in good recovery. The authors also reviewed patterns and speed of progression of neuropathy in the 30 patients with POEMS syndrome; 22 (73%) of them were unable to walk independently with the median period of 9.5 months from POEMS onset (range 0.5-51 months). Whereas the speed of neuropathy progression varies considerably among patients, some POEMS patients can show acute or subacute polyneuropathy. The early diagnosis and treatment could result in rapid improvement as shown in the present patient.

    Acute kidney injury (AKI) is a risk factor for progression to chronic kidney disease, with even subclinical AKI episodes progressing to chronic kidney disease. Several risk factors such as preexisting kidney disease, hyperglycemia, and hypertension may aggravate renal disease after AKI. However, mechanisms underlying the progression of AKI are still unclear. This study identified the effect of human cluster of differentiation 36 (CD36) overexpression on the progression of folic acid-induced AKI. Pax8-rtTA/tetracycline response element-human CD36 transgenic mice were used to elucidate the effect of human CD36 overexpression in the proximal tubules on folic acid-induced AKI. Results of histological analysis showed severely dilated tubules with casts and albuminuria in folic acid-treated transgenic mice overexpressing human CD36 compared with folic acid-treated wild-type mice. In addition, analysis of mRNA expression showed a significant increase in the collagen 3a1 gene in folic acid-treated transgenic mice overexpressing human CD 36 compared with folic acid-treated wild type mice. Human CD36-overexpressing transgenic mice showed severe pathological changes and albuminuria compared with wild-type mice. Moreover, mRNA expression of the collagen 3a1 gene increased in folic acid-treated transgenic mice. These results suggest that human CD36 overexpression is a risk factor of AKI and its progression to chronic kidney disease.

    2014-12-01

    Full Text Available Introduction: There is no significant difference between NFHS II &III with respect to under- nutrition data but Gross national income has increased many times, so poverty and unavailability of food alone cannot be the only reasons of under- nutrition. Under-nutrition is the result of many interrelated factors such as poverty, insufficient household food security, inadequate health services, poor maternal and child care practices and inadequate water and sanitation. For communities with a high prevalence of under- nutrition, it may take years or even decades before all of these factors can be addressed. Aims and Objectives:  to find out child feeding practices responsible for severe acute malnutrition among Under-five Children and to recommend a Community Action Plan based on Positive Deviance Approach to deal with under-nutrition quickly, affordably and sustainably in a culturally acceptable manner. Materials & Methods: Study design: Matched Case Control study. Sample size: 143 cases and age, socio-economic status matched 143 controls. Study place: MTC and Immunization clinic. Study Duration: May, 2013- May, 2014. Study Tool and Data Collection: Semi-structured pre-tested questionnaire. Data analysis: with help of SPSS16 (Mean, SD, Proportion, odds ratio. Results: Strong positive association was found between duration of exclusive breast feeding(both shorter and longer, prelacteals, diluted milk as weaning food, bottle feeding, giving excess milk and less solid protein diet, not able to recognize cue of hunger by mother, lack of demand feeding, and severe acute malnutrition. Conclusion: Not any nutritional programme can help in preventing SAM unless we motivate the mothers for good child feeding and rearing practices. This can be achieved by identification of the Positive Deviant mothers from the same community and SES, who can motivate the mothers of SAM children and can practically demonstrate positive child feeding practices in a culturally

    Background Outpatient Therapeutic feeding Program (OTP) brings the services for management of Severe Acute Malnutrition (SAM) closer to the community by making services available at decentralized treatment points within the primary health care settings, through the use of ready-to-use therapeutic foods, community outreach and mobilization. Little is known about the program outcomes. This study revealed the levels of program outcome indictors and determinant factors to recovery rate. Methods A retrospective cohort study was conducted on 628 children who had been managed for SAM under OTP from April/2008 to January/2012. The children were selected using systematic random sampling from 12 health posts and 4 health centers. The study relied on information of demographic characteristics, anthropometries, Plumpy'Nut, medical problems and routine medications intakes. The results were estimated using Kaplan-Meier survival curves, log-rank test and Cox-regression. Results The recovery, defaulter, mortality and weight gain rates were 61.78%, 13.85%, 3.02% and 5.23 gm/kg/day, respectively. Routine medications were administered partially and children with medical problems were managed inappropriately under the program. As a child consumed one more sachet of Plumpy'Nut, the recovery rate from SAM increased by 4% (HR = 1.04, 95%-CI = 1.03, 1.05, Pworming had 95% (HR = 1.95, 95%-CI = 1.17, 3.23) and 74% (HR = 1.74, 95%-CI = 1.07, 2.83) more probability to recover from SAM as compared to those who didn't take them. Conclusions The OTP was partially successful. Management of children with comorbidities under the program and partial administration of routine drugs were major threats for the program effectiveness. The stakeholders should focus on creating the capacity of the OTP providers on proper management of SAM to achieve fully effective program. PMID:23755286

    Disturbances in Tryptophan metabolism play a crucial role in multiple sclerosis (MS). Exercise is suspected to counteract the progress of MS and its side effects. Current research suggests alterations of Tryptophan metabolism in healthy individuals in response to exercise. We investigated the influence of acute aerobic exercise and training on Tryptophan metabolism in 57 inpatients with relapsing remitting ((RRMS) n=33) and secondary progressive ((SPMS) n=24) MS. Serotonin increased after training, whereas the kynurenine pathway was only activated in persons with RRMS. Further research is warranted to investigate whether these changes are associated with clinical measures (e.g. depressions and immune function). Copyright © 2017 Elsevier B.V. All rights reserved.

    To explore the effects of combined intervention with education and progressive muscle relaxation (PMR) on quality of life (QoL), functional disability, and positive symptoms of patients with acute schizophrenia. This randomized controlled study took place in an acute schizophrenia ward in Changsha, China. Sixty-four patients with acute schizophrenia were randomly assigned to four groups: control, education, PMR, and education plus PMR. QoL was assessed with the Quality of Life Enjoyment and Satisfaction Questionnaire Short Form. Functional disability was assessed with the Sheehan Disability Scale. Severity of positive schizophrenia symptoms was assessed with the Scale for the Assessment of Positive Symptoms. All patients were evaluated at baseline (within 72 hours before the interventions) and at the end of weeks 5 (when the interventions ended) and week 15 (a 10-week follow-up after the interventions). The sociodemographic and clinical characteristics of all four study groups were similar at baseline. Repeated-measures analysis of variance showed significant differences among the interventions in improving QoL, functional disability, and positive symptoms over time in the patients. Education and PMR alone resulted in sustained improvement of QoL during the intervention period and a 10-week follow-up but had no significant effects on functional disability or positive schizophrenia symptoms. In contrast, combined intervention with education and PMR showed better effects on improving QoL than did education or PMR alone throughout the 15-week study. It also statistically significantly improved functional disability and positive schizophrenia symptoms during the intervention period and led to sustained improvement of functional disability during the 10-week follow-up. A combined intervention with education and PMR is effective in improving QoL, functional disability, and positive symptoms in patients with acute schizophrenia. The combined intervention model could be a

    To detect the expression of long non-coding RNA-CRNDE in patients with acute myeloid leukemia and its effect on proliferation and apoptosis in acute myeloid leukemia cell line U937. 81 cases of newly diagnosed acute myeloid leukemia (AML) were enrolled, and 35 non-malignant hematological patients were selected as controls. Quantitative RT-PCR (qRT-PCR) was performed to detect the expression of lncRNA-CRNDE in the bone marrow specimens of the subjects, and the difference between the two groups was also compared. The correlation between the expression of lncRNA-CRNDE and the sex, age, classification and total survival of clinical patients was analyzed according to the clinical data. U937 cells and monocytes isolated from normal people were cultured, and the expression of lncRNA-CRNDE in acute myeloid leukemia cell line U937 and normal monocytes was compared. SiRNA-CRNDE and pcDNA-CRNDE were transfected into U937 cells, and cell counting kit-8 (CCK-8) assay was performed to detect proliferation of U937 cells, Annexin V/PI flow cytometry was carried out to detect cell apoptosis. Cell cycle was measured by flow cytometry. The expression of lncRNA-CRNDE in patients with AML and U937 cells was significantly higher than that in non-malignant hematological controls. Results of clinical data showed that the expression of lncRNA-CRNDE was associated with the classification and total survival of myeloid leukemia in clinical patients. After transfection of siRNA-CRNDE, the proliferation and cloning ability of U937 cells decreased, while the apoptosis increased (p < 0.01) and cells were arrested in G0-G1 phase. Meanwhile, after transfection of pcDNA-CRNDE, the proliferation ability of U937 cells increased significantly, which indicated that the expression of lncRNA-CRNDE might play an essential role in promoting the proliferation of U937 cells. LncRNA-CRNDE is highly expressed in the bone marrow tissues of AML patients, and the expression level is negatively correlated with the

    Full Text Available Abstract Introduction Acute promyelocytic leukaemia, an uncommon and devastating subtype of leukaemia, is highly prevalent in Latin American populations. The disease may be detected by a dentist since oral signs are often the initial manifestation. However, despite several cases describing oral manifestations of acute promyelocytic leukaemia and genetic analysis, reports of acute promyelocytic leukaemia in Hispanic populations are scarce. The identification of third molar pain as an initial clinical manifestation is also uncommon. This is the first known case involving these particular features. Case presentation A 24-year-old Latin American man without relevant antecedents consulted a dentist for pain in his third molar. After two dental extractions, the patient experienced increased pain, poor healing, jaw enlargement and bleeding. A physical examination later revealed that the patient had pallor, jaw enlargement, ecchymoses and gingival haemorrhage. Laboratory findings showed pancytopaenia, delayed coagulation times, hypoalbuminaemia and elevated lactate dehydrogenase. Splenomegaly was detected on ultrasonography. Peripheral blood and bone marrow analyses revealed a hypercellular infiltrate of atypical promyelocytic cells. Cytogenetic analysis showing genetic translocation t(15;17 further confirmed acute promyelocytic leukaemia. Despite early chemotherapy, the patient died within one week due to intracranial bleeding secondary to disseminated intravascular coagulation. Conclusion The description of this unusual presentation of acute promyelocytic leukaemia, the diagnostic difficulties and the fatal outcome are particularly directed toward dental surgery practitioners to emphasise the importance of clinical assessment and preoperative evaluation as a minimal clinically-oriented routine. This case may also be of particular interest to haematologists, since the patient's cytogenetic analysis, clinical course and therapeutic response are well

    Heart failure (HF) is associated with autonomic dysfunction. Vagus nerve stimulation has been shown to improve cardiac function both in HF patients and animal models of HF. The purpose of this present study is to investigate the effects of ganglionated plexus stimulation (GPS) on HF progression and autonomic remodeling in a canine model of acute HF post-myocardial infarction. Eighteen adult mongrel male dogs were randomized into the control (n=8) and GPS (n=10) groups. All dogs underwent left anterior descending artery ligation followed by 6-hour high-rate (180-220bpm) ventricular pacing to induce acute HF. Transthoracic 2-dimensional echocardiography was performed at different time points. The plasma levels of norepinephrine, B-type natriuretic peptide (BNP) and Ang-II were measured using ELISA kits. C-fos and nerve growth factor (NGF) proteins expressed in the left stellate ganglion as well as GAP43 and TH proteins expressed in the peri-infarct zone were measured using western blot. After 6h of GPS, the left ventricular end-diastolic volume, end-systolic volume and ejection fraction showed no significant differences between the 2 groups, but the interventricular septal thickness at end-systole in the GPS group was significantly higher than that in the control group. The plasma levels of norepinephrine, BNP, Ang-II were increased 1h after myocardial infarction while the increase was attenuated by GPS. The expression of c-fos and NGF proteins in the left stellate ganglion as well as GAP43 and TH proteins in cardiac peri-infarct zone in GPS group were significantly lower than that in control group. GPS inhibits cardiac sympathetic remodeling and attenuates HF progression in canines with acute HF induced by myocardial infarction and ventricular pacing. Copyright © 2017 Elsevier B.V.

    Chronic inflammatory disorders are thought to arise due to an interplay between predisposing host genetics and environmental factors. For example, the onset of inflammatory bowel disease is associated with enteric proteobacterial infection, yet the mechanistic basis for this association is unclear. We have shown previously that genetic defiency in TLR1 promotes acute enteric infection by the proteobacteria Yersinia enterocolitica. Examining that model further, we uncovered an altered cellular immune response that promotes the recruitment of neutrophils which in turn increases metabolism of the respiratory electron acceptor tetrathionate by Yersinia. These events drive permanent alterations in anti-commensal immunity, microbiota composition, and chronic inflammation, which persist long after Yersinia clearence. Deletion of the bacterial genes involved in tetrathionate respiration or treatment using targeted probiotics could prevent microbiota alterations and inflammation. Thus, acute infection can drive long term immune and microbiota alterations leading to chronic inflammatory disease in genetically predisposed individuals.

    Full Text Available BACKGROUND: Outpatient Therapeutic feeding Program (OTP brings the services for management of Severe Acute Malnutrition (SAM closer to the community by making services available at decentralized treatment points within the primary health care settings, through the use of ready-to-use therapeutic foods, community outreach and mobilization. Little is known about the program outcomes. This study revealed the levels of program outcome indictors and determinant factors to recovery rate. METHODS: A retrospective cohort study was conducted on 628 children who had been managed for SAM under OTP from April/2008 to January/2012. The children were selected using systematic random sampling from 12 health posts and 4 health centers. The study relied on information of demographic characteristics, anthropometries, Plumpy'Nut, medical problems and routine medications intakes. The results were estimated using Kaplan-Meier survival curves, log-rank test and Cox-regression. RESULTS: The recovery, defaulter, mortality and weight gain rates were 61.78%, 13.85%, 3.02% and 5.23 gm/kg/day, respectively. Routine medications were administered partially and children with medical problems were managed inappropriately under the program. As a child consumed one more sachet of Plumpy'Nut, the recovery rate from SAM increased by 4% (HR = 1.04, 95%-CI = 1.03, 1.05, P<0.001. The adjusted hazard ratios to recovery of children with diarrhea, appetite loss with Plumpy'Nut and failure to gain weight were 2.20 (HR = 2.20, 95%-CI = 1.31, 3.41, P = 0.001, 4.49 (HR = 1.74, 95%-CI = 1.07, 2.83, P = 0.046 and 3.88 (HR = 1.95, 95%-CI = 1.17, 3.23, P<0.001, respectively. Children who took amoxicillin and de-worming had 95% (HR = 1.95, 95%-CI = 1.17, 3.23 and 74% (HR = 1.74, 95%-CI = 1.07, 2.83 more probability to recover from SAM as compared to those who didn't take them. CONCLUSIONS: The OTP was partially successful. Management of

    Gemcitabine-associated thrombotic microangiopathy is being increasingly recognized as a serious complication of treatment. We report a normotensive patient who developed progressive hypertension after commencing gemcitabine therapy. She also developed subtle changes in her platelet count and serum creatinine months before her emergent presentation. Clinicians should be aware of new onset or worsening hypertension and \\'mild\\' biochemical changes in gemcitabine-treated patients.

    The species-specific, as well as organ-specific expression of regulated necrosis (RN)-related molecules, is not known. We determined the expression levels of tumour necrosis factor receptor-1 (TNFR1), receptor activated protein kinase (RIPK)1, RIPK3, mixed lineage kinase domain-like (MLKL), CASP8, Fas-associated protein with death domain (FADD), cellular inhibitor of apoptosis protein (CIAP)1, CIAP2, glutathione peroxidase-4 (GPX4), cyclophilin D (CYPD), CASP1, NLRP3 and poly(ADP-ribose) polymerase-1 (PARP1) in human and mouse solid organs. We observed significant differences in expression of these molecules between human and mice. In addition, we characterized their expression profiles in acute as well as persistent tissue injury and chronic tissue remodelling using acute and chronic kidney injury models. We observed that the degree and pattern of induction of RN-related molecules were highly dependent on the trigger and disease pathogenesis. Furthermore, we studied their expression patterns in mice with lupus-like systemic autoimmunity, which revealed that the expression of MLKL, GPX4 and PARP1 significantly increased in the spleen along disease progression and CASP1, RIPK1, RIPK3 and CYPD were higher at the earlier stages but were significantly decreased in the later stages. In contrast, in the kidney, the expression of genes involved in pyroptosis, e.g. NLRP3 and CASP1 were significantly increased and TNFR1, RIPK1, RIPK3, CIAP1/2 and GPX4 were significantly decreased along the progression of lupus nephritis (LN). Thus, the organ- and species-specific expression of RN-related molecules should be considered during designing experiments, interpreting the results as well as extrapolating the conclusions from one species or organ to another species or organ respectively. © 2016 The Author(s).

    Acute Cl2 exposure following industrial accidents or military/terrorist activity causes pulmonary injury and severe acute respiratory distress. Prior studies suggest that antioxidant depletion is important in producing dysfunction, however a pathophysiologic mechanism has not been elucidated. We propose that acute Cl2 inhalation leads to oxidative modification of lung lining fluid, producing surfactant inactivation, inflammation and mechanical respiratory dysfunction at the organ level. C57BL/6J mice underwent whole-body exposure to an effective 60ppm-hour Cl2 dose, and were euthanized 3, 24 and 48h later. Whereas pulmonary architecture and endothelial barrier function were preserved, transient neutrophilia, peaking at 24h, was noted. Increased expression of ARG1, CCL2, RETLNA, IL-1b, and PTGS2 genes was observed in bronchoalveolar lavage (BAL) cells with peak change in all genes at 24h. Cl2 exposure had no effect on NOS2 mRNA or iNOS protein expression, nor on BAL NO3(-) or NO2(-). Expression of the alternative macrophage activation markers, Relm-α and mannose receptor was increased in alveolar macrophages and pulmonary epithelium. Capillary surfactometry demonstrated impaired surfactant function, and altered BAL phospholipid and surfactant protein content following exposure. Organ level respiratory function was assessed by forced oscillation technique at 5 end expiratory pressures. Cl2 exposure had no significant effect on either airway or tissue resistance. Pulmonary elastance was elevated with time following exposure and demonstrated PEEP refractory derecruitment at 48h, despite waning inflammation. These data support a role for surfactant inactivation as a physiologic mechanism underlying respiratory dysfunction following Cl2 inhalation. Copyright © 2014 Elsevier Inc. All rights reserved.

    To describe radiologic findings of adenovirus pneumonia and to understand clinico-radiological features associated with progression to acute respiratory distress syndrome (ARDS) in patients with adenovirus pneumonia. This study included 19 patients diagnosed with adenovirus pneumonia at a tertiary referral center, in the period between March 2003 and April 2015. Clinical findings were reviewed, and two radiologists assessed imaging findings by consensus. Chi-square, Fisher's exact, and Student's t tests were used for comparing patients with and without subsequent development of ARDS. Of 19 patients, nine were immunocompromised, and 10 were immunocompetent. Twelve patients (63%) progressed to ARDS, six of whom (32%) eventually died from the disease. The average time for progression to ARDS from symptom onset was 9.6 days. Initial chest radiographic findings were normal (n = 2), focal opacity (n = 9), or multifocal or diffuse opacity (n = 8). Computed tomography (CT) findings included bilateral (n = 17) or unilateral (n = 2) ground-glass opacity with consolidation (n = 14) or pleural effusion (n = 11). Patients having subsequent ARDS had a higher probability of pleural effusion and a higher total CT extent compared with the non-ARDS group (p = 0.010 and 0.007, respectively). However, there were no significant differences in clinical variables such as patient age and premorbid condition. Adenovirus pneumonia demonstrates high rates of ARDS and mortality, regardless of patient age and premorbid conditions, in the tertiary care setting. Large disease extent and presence of pleural effusion on CT are factors suggestive of progression to ARDS.

    Previously we have shown that 90% of streptozotocin (STZ)-induced type-1 diabetic (DB) mice survive from acute renal failure (ARF) and death induced by a normally LD 9 dose (75 mg/kg, i.p.) of the nephrotoxicant S-1,2-dichlorovinyl-L-cysteine (DCVC). This remarkable protection is due to a combination of slower progression of DCVC-initiated renal injury and increased compensatory nephrogenic tissue repair in the DB kidneys. BRDU immunohistochemistry revealed that the DB condition led to 4-fold higher number of proximal tubular cells (PTC) entering S-phase of cell cycle. In the present study, we tested the hypothesis that DB-induced augmentation of PTC into S-phase is accompanied by overexpression of the calpain-inhibitor calpastatin, which endogenously prevents the progression of DCVC-initiated renal injury mediated by the calpain escaping out of damaged PTCs. Immunohistochemical detection of renal calpain and its activity in the urine, over a time course after treatment with the LD 9 dose of DCVC, indicated progressive increase in leakage of calpain into the extracellular spaces of the injured PTCs of the non-diabetic (NDB) kidneys as compared to the DB kidneys. Calpastatin expression was minimally detected in the NDB kidneys, using immunohistochemistry, over the time course. On the other hand, consistently higher number of tubules in the DB kidney showed calpastatin expression over the time course. The lower leakage of calpain in the DB kidneys was commensurate with constitutively higher expression of calpastatin in the S-phase-laden PTCs of these mice. To test the protective role of newly divided/dividing PTCs, DB mice were given the anti-mitotic agent colchicine (CLC) (2 mg/kg and 1.5 mg/kg, i.p., on days 8 and 10 after STZ injection) prior to challenge with a LD 9 dose of DCVC, which led to 100% mortality by 48 h. Mortality was due to rapid progression of DCVC-initiated renal injury, suggesting that newly divided/dividing cells are instrumental in mitigating

    Cocaine induces fast dopamine increases in brain striatal regions, which are recognized to underlie its rewarding effects. Both dopamine D1 and D2 receptors are involved in cocaine's reward but the dynamic downstream consequences of cocaine effects in striatum are not fully understood. Here we used transgenic mice expressing EGFP under the control of either the D1 receptor (D1R) or the D2 receptor (D2R) gene and microprobe optical imaging to assess the dynamic changes in intracellular calcium ([Ca 2+ ] i ) responses (used as marker of neuronal activation) to acute cocaine in vivo separately for D1R- versus D2R-expressing neurons in striatum. Acute cocaine (8 mg/kg, i.p.) rapidly increased [Ca 2+ ] i in D1R-expressing neurons (10.6 ± 3.2%) in striatum within 8.3 ± 2.3 min after cocaine administration after which the increases plateaued; these fast [Ca 2+ ] i increases were blocked by pretreatment with a D1R antagonist (SCH23390). In contrast, cocaine induced progressive decreases in [Ca 2+ ] i in D2R-expressing neurons (10.4 ± 5.8%) continuously throughout the 30 min that followed cocaine administration; these slower [Ca 2+ ] i decreases were blocked by pretreatment with a D2R antagonist (raclopride). Since activation of striatal D1R-expressing neurons (direct-pathway) enhances cocaine reward, whereas activation of D2R expressing neurons suppresses it (indirect-pathway) (Lobo et al., 2010), this suggests that cocaine's rewarding effects entail both its fast stimulation ofD1R (resulting in abrupt activation of direct-pathway neurons) and a slower stimulation of D2R (resulting in longer-lasting deactivation of indirect-pathway neurons). We also provide direct in vivo evidence of D2R and D1R interactions in the striatal responses to acute cocaine administration.

  3. Inflammatory cascades driven by tumor necrosis factor-alpha play a major role in the progression of acute liver failure and its neurological complications.

    Full Text Available Acute liver failure (ALF due to ischemic or toxic liver injury is a clinical condition that results from massive loss of hepatocytes and may lead to hepatic encephalopathy (HE, a serious neuropsychiatric complication. Although increased expression of tumor necrosis factor-alpha (TNF-α in liver, plasma and brain has been observed, conflicting results exist concerning its roles in drug-induced liver injury and on the progression of HE. The present study aimed to investigate the therapeutic value of etanercept, a TNF-α neutralizing molecule, on the progression of liver injury and HE in mice with ALF resulting from azoxymethane (AOM hepatotoxicity.Mice were administered saline or etanercept (10 mg/kg; i.p. 30 minutes prior to, or up to 6 h after AOM. Etanercept-treated ALF mice were sacrificed in parallel with vehicle-treated comatose ALF mice and controls. AOM induced severe hepatic necrosis, leading to HE, and etanercept administered prior or up to 3 h after AOM significantly delayed the onset of coma stages of HE. Etanercept pretreatment attenuated AOM-induced liver injury, as assessed by histological examination, plasma ammonia and transaminase levels, and by hepatic glutathione content. Peripheral inflammation was significantly reduced by etanercept as shown by decreased plasma IL-6 (4.1-fold; p<0.001 and CD40L levels (3.7-fold; p<0.001 compared to saline-treated ALF mice. Etanercept also decreased IL-6 levels in brain (1.2-fold; p<0.05, attenuated microglial activation (assessed by OX-42 immunoreactivity, and increased brain glutathione concentrations.These results indicate that systemic sequestration of TNF-α attenuates both peripheral and cerebral inflammation leading to delayed progression of liver disease and HE in mice with ALF due to toxic liver injury. These results suggest that etanercept may provide a novel therapeutic approach for the management of ALF patients awaiting liver transplantation.

    The objectives of this study were to determine the effect of feed presentation on meal frequency and duration, as well as diurnal feeding patterns of dairy calves, and to assess any longer-term differences in feeding patterns resulting from previous experience. Twenty Holstein bull calves were exposed from wk 1 to 8 of life to 1 of 2 feed presentation treatments: concentrate and chopped grass hay (Feed was provided ad libitum. Calves received 8L/d of milk replacer (1.2 kg of dry matter), with the amount progressively reduced after 5 wk to facilitate weaning by the end of wk 7. At the beginning of wk 9, all calves received the MIX diet and remained on trial for an additional 3 wk. Feeding behavior was recorded from video for 4d during wk 6, 8, 9, and 11. In wk 6, calves fed MIX spent more time feeding than calves fed COM (56.7 vs. 46.8 min/d). In wk 8, calves fed MIX spent more time feeding (174.0 vs. 139.1 min/d) and had a lower rate of intake (11.5 vs. 14.7 g/min) compared with calves fed COM. Meal frequency was similar between treatments (12.2 meals/d). Diurnal feeding patterns in wk 8 were also affected by feed presentation, with calves fed MIX spending less time feeding at time of feed delivery and more time feeding throughout the rest of the daylight hours than calves fed COM. Diurnal feeding patterns of hay and concentrate in wk 8 differed for calves fed COM, with more time spent consuming hay at time of feed delivery and less time spent consuming hay throughout the rest of the day. Once calves previously fed COM were transitioned to the MIX diet in wk 9, meal frequency, meal duration, and diurnal feeding patterns were similar between treatments: both treatments spent similar amounts of time feeding (173.9 min/d) and had similar peaks in feeding activity at time of feed delivery, sunrise, and sunset. Provision of hay and concentrate to young calves as a mixed ration, compared with separate components, increases time spent feeding and results in more evenly

    Immunosuppression in acute myeloid leukemia (AML) is an important mechanism of tumor escape. CD200, as an immunosuppressive molecule, is overexpressed in some hematological malignancies and it has also been shown to be an independent prognostic factor in AML. In the current study, simultaneous CD200 expression and Foxp3(+) regulatory T cell levels were investigated in Iranian patients with AML by flow cytometry. We also assessed the effect of CD200-CD200R blockade on Th1 and T-reg cytokine production and T cell proliferation in autologous AML- and monocyte-DC mixed lymphocyte reactions (MLRs). ELISA assay was performed to detect IL-2, IL-12, IFN-γ, IL-10, and TGF-β production in MLR supernatants. Expression of Foxp3, IL-10, and TGF-β mRNAs in MLRs were detected by real-time PCR. Our results demonstrated significant overexpression of CD200 (P = 0.001) in association with higher frequencies of Foxp3(+) T cells in AML patients (r = 0.8, P T cell levels with lower Foxp3 intensity was also shown in CD200-CD200R-blocked MLRs. Expression of IL-10 mRNA declined significantly only in AML-DC MLRs where CD200-CD200R interaction was blocked and the same result was observed for TGF-β and Foxp3 mRNA in both AML- and monocyte-DC MLRs. These data present a significant role for CD200 in suppressing anti-tumor immune response through stimulation of regulatory mechanisms in AML patients and suggest that CD200 may have a prognostic value in this malignancy and its blockade may be used as a target for AML immunotherapy.

    Huntington disease is an inherited neurodegenerative disorder characterized by motor, cognitive, psychiatric and metabolic symptoms. We recently published a study describing that the BACHD rat model of HD shows an obesity phenotype, which might affect their motivation to perform food-based behavioral tests. Further, we argued that using a food restriction protocol based on matching BACHD and wild type rats' food consumption rates might resolve these motivational differences. In the current study, we followed up on these ideas in a longitudinal study of the rats' performance in a progressive ratio test. We also investigated the phenotype of reduced food consumption rate, which is typically seen in food-restricted BACHD rats, in greater detail. In line with our previous study, the BACHD rats were less motivated to perform the progressive ratio test compared to their wild type littermates, although the phenotype was no longer present when the rats' food consumption rates had been matched. However, video analysis of food consumption tests suggested that the reduced consumption rate found in the BACHD rats was not entirely based on differences in hunger, but likely involved motoric impairments. Thus, restriction protocols based on food consumption rates are not appropriate when working with BACHD rats. As an alternative, we suggest that studies where BACHD rats are used should investigate how the readouts of interest are affected by motivational differences, and use appropriate control tests to avoid misleading results. In addition, we show that BACHD rats display distinct behavioral changes in their progressive ratio performance, which might be indicative of striatal dysfunction.

Further, we assessed the relationship between the expression of membrane cofactor protein (MCP by immunohistochemical staining in human renal grafts and their clinical course.qRT-PCR results showed that the expression of Cregs, CD59 and rodent-specific complement regulator complement receptor 1-related gene/protein-y (Crry, was diminished in the rat allograft model especially on day 5 after transplantation in comparison with the syngeneic model. In contrast, the expression of complement components and receptors: C3, C3a receptor, C5a receptor, Factor B, C9, C1q, was increased, but not the expression of C4 and C5, indicating a possible activation of the alternative pathway. When anti-Crry and anti-CD59 mAbs were administered to the allograft, the survival period for each group was shortened. In the human ATCMR cases, the group with higher MCP expression in the grafts showed improved serum creatinine levels after the ATCMR treatment as well as a better 5-year graft survival rate.We conclude that the expression of Cregs in allografts is connected with ATCMR. Our results suggest that controlling complement activation in renal grafts can be a new strategy for the treatment of ATCMR.

    The extent to which renal progression after acute kidney injury (AKI) arises from an initial step drop in kidney function (incomplete recovery), or from a long-term trajectory of subsequent decline, is unclear. This makes it challenging to plan or time post-discharge follow-up. This study of 14651 hospital survivors in 2003 (1966 with AKI, 12685 no AKI) separates incomplete recovery from subsequent renal decline by using the post-discharge estimated glomerular filtration rate (eGFR) rather than the pre-admission as a new reference point for determining subsequent renal outcomes. Outcomes were sustained 30% renal decline and de novo CKD stage 4, followed from 2003-2013. Death was a competing risk. Overall, death was more common than subsequent renal decline (37.5% vs 11.3%) and CKD stage 4 (4.5%). Overall, 25.7% of AKI patients had non-recovery. Subsequent renal decline was greater after AKI (vs no AKI) (14.8% vs 10.8%). Renal decline after AKI (vs no AKI) was greatest among those with higher post-discharge eGFRs with multivariable hazard ratios of 2.29 (1.88-2.78); 1.50 (1.13-2.00); 0.94 (0.68-1.32) and 0.95 (0.64-1.41) at eGFRs of 60 or more; 45-59; 30-44 and under 30, respectively. The excess risk after AKI persisted over ten years of study, irrespective of AKI severity, or post-episode proteinuria. Thus, even if post-discharge kidney function returns to normal, hospital admission with AKI is associated with increased renal progression that persists for up to ten years. Follow-up plans should avoid false reassurance when eGFR after AKI returns to normal. Copyright © 2017 International Society of Nephrology. Published by Elsevier Inc. All rights reserved.

    2017-01-01

    Responsive feeding is a derivative of responsive parenting that has been applied to infant and young child feeding. With a theoretical basis in the reciprocal interactions between parents and children, responsive feeding is particularly relevant during complementary feeding as young children progress from an exclusively milk-based liquid diet to the family diet and self-feeding. The period of complementary feeding includes multiple developmental changes that may threaten a successful transition and lead to growth and feeding problems. In spite of high rates of global childhood underweight, stunting, overweight, and obesity, and the inclusion of responsive feeding in the World Health Organization's Global Strategy for Infant and Young Child Feeding, there have been few intervention trials of responsive feeding. The aim of this chapter is to examine how parents and young children navigate the progression in feeding, with an emphasis on complementary feeding, and to address the following topics: (1) navigating the progression of feeding development, (2) provision of responsive feeding, (3) preventing or resolving growth and feeding problems, (4) responsive feeding research, and (5) strategies to promote healthy mealtime interactions. To advance responsive feeding research and practice, clarity is needed in both measurement and intervention strategies, guided by the reciprocity between parent and child interactions inherent in the theoretical basis of responsive feeding. © 2017 Nestec Ltd., Vevey/S.

    Full Text Available Acute kidney injury (AKI is common after gastric surgery for gastric cancer and associated with adverse outcomes. However, the impact of transient or persistent AKI on clinical outcomes after gastric surgery for gastric cancer has not been described. We performed a retrospective study of 4,886 patients with normal renal function who underwent partial or total gastrectomy for gastric cancer between June 2002 and December 2012. AKI patients were classified as transient and persistent AKI based on the return of serum creatinine to the level indicating no AKI within 7 days. Our outcomes included occurrence of new-onset chronic kidney disease (CKD and mortality 1 year after gastric surgery. AKI occurred in 638 (13.1% after gastric surgery. Transient AKI was documented in 574 (90%. Use of diuretics and contrast agents was a common risk factor for persistent and transient AKI. Length of intensive care unit (ICU and hospital stay, and ICU admission rate were higher in patients with transient AKI than in those without AKI. Although patients with persistent AKI had a higher new-onset CKD 1 year after gastric surgery after adjusting for multiple covariates, transient AKI was not associated with new-onset CKD. The 1-year mortality rates were significantly higher in patients with transient and persistent AKI. Not only persistent AKI but transient AKI is associated with increased risk of hospital complications and a significantly higher risk of long-term mortality than patients without AKI after gastric surgery. Moreover, persistent AKI, but not transient AKI, is associated with CKD progression at 1 year.

    Full Text Available BACKGROUND Nutrients form the fuel for the body, which comes in the form of carbohydrates, proteins and lipids. The body is intended to burn fuels in order to perform work. Starvation with malnutrition affects the postoperative patients and patients with acute pancreatitis. There is an increased risk of nosocomial infections and a delay in the wound healing may be noted. They are more prone for respiratory tract infections. Enteral Nutrition (EN delivers nutrition to the body through gastrointestinal tract. This also includes the oral feeding. This study will review the administration, rationale and assess the pros and cons associated with the early initiation of enteral feeding. The aim of this study is to evaluate if early commencement of enteral nutrition compared to traditional management (delayed enteral feeding is associated with fewer complications and improved outcome-  In patients undergoing elective/emergency gastrointestinal surgery.  In patients with acute pancreatitis. It is also used to determine whether a period of starvation (nil by mouth after gastrointestinal surgery or in the early days of acute pancreatitis is beneficial in terms of specific outcomes. MATERIALS AND METHODS A prospective cohort interventional study was conducted using 100 patients from July 2012 to November 2012. Patients satisfying the inclusion and exclusion criteria were included in the study. Patients admitted in my unit for GIT surgeries or acute pancreatitis constituted the test group, while patients admitted in other units for similar disease processes constituted the control group. RESULTS Our study concluded that early enteral feeding resulted in reduced incidence of surgical site infections. When the decreased length of stay, shorter convalescent period and the lesser post-interventional fatigue were taken into account, early enteral feeding has a definite cost benefit.CONCLUSION Early enteral feeding was beneficial associated with fewer

    In Exp. 1, individual performance and daily DMI was measured on 70 crossbred weaned calves during a 70-d period using a GrowSafe system (GrowSafe Systems Ltd., Airdrie, AB, Canada) at the University of Florida North Florida Research and Education Center Feed Efficiency Facility (FEF). Calves were fed a low-concentrate (LC) growing diet, blocked by weight and sex, and then randomly assigned to pens to receive either no additional supplement (CON; n = 35) or receive a supplement of anti-phospholipase A2 antibody (aPLA2) at an inclusion rate of 0.6% of the diet DM (n = 35). After the 70-d feed efficiency (FE) trial (Phase 1), calves were loaded into a commercial livestock trailer and were driven for approximately 1,600 km during 24 h. Upon return to the FEF (Phase 2), calves were relocated to the same pens and groups and received the same diets and treatments for 28 d. Blood samples from each calf were collected on d 0, 1, 3, 5, 7, 14, 21, and 28 relative to initiation of transportation and were analyzed for determination of concentrations of plasma ceruloplasmin and haptoglobin. In Phase 1, initial BW (242.0 ± 3.7 kg; P = 0.92), BW at d 70 (313.0 ± 4.1 kg; P = 0.79), and ADG (1.01 ± 0.02 kg; P = 0.95) were similar between treatments. However, daily DMI was greater (P = 0.01) for CON (9.18 ± 0.15 kg) than aPLA2 (8.53 ± 0.15 kg). In addition, residual feed intake was greater (P = 0.002) for CON (0.389 ± 0.110 kg/d) than aPLA2 calves (-0.272 ± 0.110 kg/d). In Phase 2, after transportation, there were no differences between treatments on BW loss due to transportation shrink (26.0 ± 0.6 kg; P = 0.86), BW at d 28 (339.0 ± 4.1 kg; P = 0.72), ADG (1.28 ± 0.03 kg/d; P = 0.72), G:F (0.164 ± 0.004; P = 0.83), and concentrations of plasma haptoglobin (0.08 ± 0.02 mg/mL; P = 0.41). However, concentrations of plasma ceruloplasmin were greater (P calves (14.3 ± 0.3 mg/dL) compared to aPLA2 calves (13.0 ± 0.3 mg/dL). In Exp. 2, the effects of aPLA2 inclusion on LC and

    To clarify the toxic effects of Iranian Heavy Crude Oil (IHCO) from the "Hebei spirit" oil spill, innate immune toxic effects defending on biotransformation pathway have been investigated on fish exposed to IHCO. Juvenile rockfish were exposed to IHCO in gelatin capsules by feeding. The effects on multiple fish biotransformation enzymes (Cytochrome P4501A and glutathione-S-transferase) and the expression level of the several immune response genes, including interleukin-1beta, granulocyte colony-stimulating factor and Cathepsin L, were measured in the liver, spleen and kidney. The tissue-specific expression patterns of these genes demonstrated that the highest expression levels of Cytochrome P4501A, glutathione-S-transferase, interleukin-1beta, granulocyte colony-stimulating factor, interferon stimulated gene 15 and Cathepsin L were found in the liver and that the TNF receptor was high in spleen. The oil-fed fish had significantly higher concentrations of biliary fluorescent metabolites and Cytochrome P4501A expression during the initial stage (12 ∼ 48 h after exposure) than those in the liver and kidney of the sham group. Similarly, the highest mRNA expression levels of interleukin-1beta and granulocyte colony-stimulating factor were detected in the liver at the early stages of exposure (12 h after exposure). Following exposure, the levels of interferon stimulated gene 15 and granulocyte colony-stimulating factor mRNA remained high at 120 h after exposure in the liver but the levels of interleukin-1beta and Cathepsin L gradually decreased to an expression level equal to or less than the sham group. Our data suggest that the innate immune and hepatodetoxification responses in oil-fed fish were induced at the initial stage of exposure to the IHCO at the same time but several immune-related genes decreased to less than that of the sham group after the initial stage of response. Therefore, immune disturbances in fish exposed to IHCO may allow the pathogens, including

    ón como el aseguramiento de la provisión de agua potable para el recién nacido.OBJECTIVE: To assess the effect of exclusive breastfeeding and its interactions with selected socioeconomic factors, on the incidence of acute infantile diarrhea during the first three months of life. MATERIAL AND METHODS: A prospective cohort study with a follow up of three months was conducted in 327 mother and child pairs, living in the city of Durango, Mexico, between April and June 1994. Data analyses included simple univariate and bivariate cross-tabulations, as well as multivariate logistic regression models with random effects. RESULTS: Infants who were not exclusively breastfed were at a significantly increased risk of having acute diarrhea during early infancy (ORcombined breastfeeding= 3.23; 95% CI 1.84-5.68 and ORartificial breastfeeding=4.36; 95% CI 2.32-8.19. Moreover, the protective effect of breastfeeding was independent from the effects of the following factors: poor maternal education, lack of social support for baby care, and being an adolescent mother. However, lack of potable water and lack of sewerage were potential effect modifiers of type of lactation deltaG=9.26; p=0.09; ORno water/no sewerage= 2.58; 95% CI 1.10-6.03 in the final multivariate model, for simultaneous lack of potable water and sewerage, which is greater than the sum of the individual OR for each variable. CONCLUSIONS: Similar to previous studies, exclusive breastfeeding was found to have great importance, since this practice protects the child's health and allows for a better development, despite unfavorable social and economic conditions. In particular, it seems that the protection conferred by breastfeeding is stronger when home conditions are poor, but this same condition presents an intervention opportunity, particularly the assurance of potable water provision for the infant when breastfeeding is not an option.

  1. Children with Moderate Acute Malnutrition with No Access to Supplementary Feeding Programmes Experience High Rates of Deterioration and No Improvement: Results from a Prospective Cohort Study in Rural Ethiopia.

    Full Text Available Children with moderate acute malnutrition (MAM have an increased risk of mortality, infections and impaired physical and cognitive development compared to well-nourished children. In parts of Ethiopia not considered chronically food insecure there are no supplementary feeding programmes (SFPs for treating MAM. The short-term outcomes of children who have MAM in such areas are not currently described, and there remains an urgent need for evidence-based policy recommendations.We defined MAM as mid-upper arm circumference (MUAC of ≥11.0 cm and <12.5 cm with no bilateral pitting oedema to include Ethiopian government and World Health Organisation cut-offs. We prospectively surveyed 884 children aged 6-59 months living with MAM in a rural area of Ethiopia not eligible for a supplementary feeding programme. Weekly home visits were made for seven months (28 weeks, covering the end of peak malnutrition through to the post-harvest period (the most food secure window, collecting anthropometric, socio-demographic and food security data.By the end of the study follow up, 32.5% (287/884 remained with MAM, 9.3% (82/884 experienced at least one episode of SAM (MUAC <11 cm and/or bilateral pitting oedema, and 0.9% (8/884 died. Only 54.2% of the children recovered with no episode of SAM by the end of the study. Of those who developed SAM half still had MAM at the end of the follow up period. The median (interquartile range time to recovery was 9 (4-15 weeks. Children with the lowest MUAC at enrolment had a significantly higher risk of remaining with MAM and a lower chance of recovering.Children with MAM during the post-harvest season in an area not eligible for SFP experience an extremely high incidence of SAM and a low recovery rate. Not having a targeted nutrition-specific intervention to address MAM in this context places children with MAM at excessive risk of adverse outcomes. Further preventive and curative approaches should urgently be considered.

    Protein deficiency is a major problem in critically ill patients. Egg white powder recently became a standard additive for protein supplementation in our unit. However, clinical data are not available to support egg white powder supplementation compared to standard protein casein supplementation. This study aimed to determine the change of serum prealbumin (PAB) levels of egg white powder compared to casein additive in standard enteral feeding in critically ill patients with respiratory failure. A prospective double-blind, randomized, non-inferiority study was conducted in patients with acute respiratory failure in the medical intensive care unit and respiratory care unit. These patients randomly received 1500 kcal/day of enteral nutrition support with 40 g/day of protein additives by either egg white protein powder or casein protein for 7 days. The serum PAB and C-reactive protein (CRP) levels were measured on days 1, 3, 5, and 7. Repeated-measures ANOVA determined the group effects displayed by serum PAB and CRP levels. p values egg white powder group. The clinical characteristics, baseline nutritional status, and biochemistries were not significantly different between the groups. No statistically significant differences were seen in the serum PAB and serum CRP levels between the two groups. The average mean ± SEM difference of serum PAB level between the groups was 2.3 ± 2.5 mg% (p = 0.58). The levels of PAB between the egg white protein additive and casein protein additive were not significantly different and less than the non-inferior margin.

    2014-05-01

    This article will summarize recent progress in research in the area of complementary feeding as it relates to childhood obesity. Newly emerged findings demonstrate how research on contributing factors has shifted. Examining nutrient and caloric intakes alone has failed to answer the critical question, 'Why are some children obese, whereas others are not?' Recent research explores parental attitudes, beliefs and parental feeding styles as contributing factors. Studies examining the impact of specific macronutrients on obesity risk may have partially uncovered a link between consistently high protein intakes during infancy and an elevated obesity risk, at least until the second year of life. However, this relationship was not evident in all studies evaluated in a systematic review this year. Childhood obesity is not linked to any specific types of foods or food groups during the complementary feeding period. Adherence to dietary guidelines is associated with increased lean body mass, but not BMI or fat mass. Complementary feeding practices, socioeconomic and other family dynamics at least partially explain obesity risk. As young infants are dependent on adults for nourishment, parental attitudes and beliefs about infant nutrition and actual feeding practices directly influence infant nutritional status. Early nutrition interventions to prevent obesity should take nutrition belief systems, parental feeding styles, socioeconomic and educational status, among other characteristics into consideration.

    Chagas disease (infection by the protozoan Trypanosoma cruzi) is a major parasitic disease of the Americas and one of the main neglected tropical diseases. Although various routes of transmission sre recognized, the risk for transmission of the infection through breast-feeding has not clearly been established. We reviewed the literature on transmission of T. cruzi through breast-feeding to provide breast-feeding mothers with Chagas disease with medical guidance. Although data from animal studies and human studies are scarce, we do not recommend that mothers with Chagas disease discontinue breast-feeding, unless they are experiencing the acute phase of the disease, reactivated disease resulting from immunosuppression, or bleeding nipples. In these cases, thermal treatment of milk before feeding the infant may be considered.

    2018-01-01

    This Phase 1/2, dose-escalating study of rigosertib enrolled 22 patients with higher-risk myelodysplastic syndromes (MDS) (n=9) and acute myeloid leukemia (AML; n=13) who had relapsed or were refractory to standard therapy and for whom no second-line therapies were approved. Patients received 3- to 7-day continuous intravenous infusions of rigosertib, an inhibitor of Ras-effector pathways that interacts with the Ras-binding domains, common to several signaling proteins including Raf and PI3 kinase. Rigosertib was administered at doses of 650-1700mg/m 2 /day in 14-day cycles. Initial dose escalation followed a Fibonacci scheme, followed by recommended phase 2 dose confirmation in an expanded cohort. Rigosertib was well tolerated for up to 23 cycles, with no treatment-related deaths and 18% of patients with related serious adverse events (AEs). Common AEs were fatigue, diarrhea, pyrexia, dyspnea, insomnia, and anemia. Rigosertib exhibited biologic activity, with reduction or stabilization of bone marrow blasts and improved peripheral blood counts in a subset of patients. Ten of 19 evaluable patients (53%) demonstrated bone marrow/peripheral blood responses (n=4 MDS, n=1 AML) or stable disease (n=3 MDS, n=2 AML). Median survival was 15.7 and 2.0 months for responders and non-responders, respectively. Additional studies of rigosertib are ongoing in higher-risk MDS (NCT00854646). Copyright © 2017 Elsevier Ltd.

    2016-07-01

    Full Text Available The harmful effects of particulate matter with an aerodynamic diameter of <2.5 µm (PM2.5 and its association with acute coronary syndrome (ACS has gained increased attention in recent years. Significant associations between PM2.5 and ACS have been found in most studies, although sometimes only observed in specific subgroups. PM2.5-induced detrimental effects and ACS arise through multiple mechanisms, including endothelial injury, an enhanced inflammatory response, oxidative stress, autonomic dysfunction, and mitochondria damage as well as genotoxic effects. These effects can lead to a series of physiopathological changes including coronary artery atherosclerosis, hypertension, an imbalance between energy supply and demand to heart tissue, and a systemic hypercoagulable state. Effective strategies to prevent the harmful effects of PM2.5 include reducing pollution sources of PM2.5 and population exposure to PM2.5, and governments and organizations publicizing the harmful effects of PM2.5 and establishing air quality standards for PM2.5. PM2.5 exposure is a significant risk factor for ACS, and effective strategies with which to prevent both susceptible and healthy populations from an increased risk for ACS have important clinical significance in the prevention and treatment of ACS.

    We investigated cytotoxic mechanisms evoked by the spongean alkaloids aaptamine (Aa) and aeroplysinin-1 (Ap), applied alone and in combination with daunorubicin, employing acute myeloid leukemia (AML) cells. Aa and Ap reduced the viability of AML cells in a dose dependent manner with IC50 of 10-20 µM. Ap triggered apoptotic cell death more efficiently than Aa. Both alkaloids increased the protein level of S139-phosphorylated H2AX (γH2AX), which however was independent of the induction of DNA damage. Expression of the senescence markers p21 and p16 was increased, while the phosphorylation level of p-Chk-2 was reduced following Aa treatment. As a function of dose, Aa and Ap protected or sensitized AML cells against daunorubicin. Protection by Aa was paralleled by reduced formation of ROS and lower level of DNA damage. Both Aa and Ap attenuated daunorubicin-stimulated activation of the DNA damage response (DDR) as reflected on the levels of γH2AX, p-Kap-1 and p-Chk-1. Specifically Ap restored the decrease in S10 phosphorylation of histone H3 resulting from daunorubicin treatment. The cytoprotective effects of Aa and Ap were independent of daunorubicin import/export. Both Aa and Ap abrogated daunorubicin-induced accumulation of cells in S-phase. Inhibition of DNA synthesis was specific for Ap. The data show that Aa and Ap have both congruent and agent-specific pleiotropic effects that are preferential for anticancer drugs. Since Ap showed a broader spectrum of anticancer activities, this compound is suggested as novel lead compound for forthcoming in vivo studies elucidating the usefulness of spongean alkaloids in AML therapy.

    Soluble urokinase-type plasminogen activator receptor (suPAR) is a glycoprotein secreted during inflammation and infections. Moreover, increased levels of suPAR are observed after hypoxia and ischaemia. The aim of the study was to assess whether suPAR could represent a useful marker of acute pancreatitis (AP) severity. We have observed a cohort of 126 prospectively enrolled patients. Based on the presence of persistent organ failure (more than 48 h) and local complications (diagnosis of moderate AP [MSAP]), patients were classified into three groups: mild AP (MAP), moderate and severe AP (SAP). The blood samples were taken on admission for detecting suPAR concentrations. AP was considered severe in 33 patients (26.2%), MSAP was found in 37 patients (29.4%), and MAP was found in 56 patients (44,4%). The AUC for SAP predicted by suPAR was 0.993. The calculated cut-off point for prognosis SAP is 4.75 ng/mL. The BISAP score of ≥3 for detection of SAP had sensitivity and specificity of 94.6% and 63.6%, respectively. The AUC for severity predicted by BISAP amounted to 0.916. Additionally, suPAR turned out to be a good predictor of fatal AP: for the cut-off point 7.05 ng/mL, the AUC was 0.917. The AUC for death prediction in AP patients based on the BISAP score ≥3 was 0.894. suPAR concentration is a promising new diagnostic and prognostic indicator in SAP obtainable in the early stage of disease. Larger studies are recommended to evaluate this role further. Copyright © 2016 IAP and EPC. Published by Elsevier B.V. All rights reserved.

    The International Classification of Functioning, Disability, and Health (ICF) provides models for functions and disabilities. The ICF is presented as a frame that enables organizing physical therapists' clinical practice for application. The purpose of the present study was to describe processes through which stroke patients are assessed and treated based on the ICF model. The patient was a 65-year-old female diagnosed with right cerebral artery infarction with left hemiparesis. Progressive interventions were applied, such as those aiming at sitting and standing for the first two weeks, gait intervention for the third and fourth weeks, and those aiming at sitting from a standing position for the fifth and sixth weeks. The ICF model provides rehabilitation experts with a frame that enables them to accurately identify and understand their patients' problems. The ICF model helps the experts understand not only their patients' body structure, function, activity, and participation, but also their problems related to personal and environmental factors. The experts could efficiently make decisions and provide optimum treatment at clinics using the ICF model.

    2011-08-01

    Full Text Available Acute paraplegia is a rare but catastrophic complication of surgeries performed on aorta and corrective operations of vertebral column. Trauma to spinal cord after spinal anesthesia and ischemia of spinal cord also may lead to acute paraplegia. Acute paraplegia as a complication of general anesthesia in surgeries performed on sites other than aorta and vertebral column is very rare. Here we present a 56 year old woman with acute paraplegia due to spinal cord infarction after laparoscopic cholecystectomy under general anesthesia probably caused by atherosclerosis of feeding spinal arteries and ischemia of spinal cord after reduction of blood flow possibly due to hypotension during general anesthesia.

    We tried to evaluate a putative negative effect on coronary atherosclerosis in patients receiving intracoronary infusion of unfractionated bone marrow mononuclear cells (BMMC) following an acute ST-elevation myocardial infarction. Peripheral blood mononuclear cells or enriched CD133(+) BMMC have been associated with accelerated atherosclerosis of the distal segment of the infarct related artery (IRA). Thirty-seven patients with ST-elevation myocardial infarction from the TECAM pilot study underwent intracoronary infusion of autologous BMMC 9 +/- 3.1 days after onset of symptoms. We compared angiographic changes from baseline to 9 months of follow-up in the distal non-stented segment of the IRA, as well as in the contralateral coronary artery, with a matched control group. A subgroup of 15 treated patients underwent additional IVUS within the distal segment of the IRA. No difference between stem cell and control group were found regarding changes in minimum lumen diameter (0.006 +/- 0.42 vs 0.06 +/- 0.41 mm, P = ns) and the percentage of stenosis (-2.68 +/- 12.33% vs -1.78 +/- 8.75%, P = ns) at follow-up. Likewise, no differences were seen regarding changes in the contralateral artery (minimum lumen diameter -0.004 +/- 0.54 mm vs -0.06 +/- 0.35 mm, P = ns). In the intravascular ultrasound substudy, no changes were demonstrated comparing baseline versus follow-up in maximum area stenosis and plaque volume. In this pilot study, analysis of a subgroup of patients found that intracoronary injection of unfractionated BMMC in patients with acute ST-elevation myocardial infarction was not associated with accelerated atherosclerosis progression at mid term. Prospective, randomised studies in large cohorts with long-term angiographic and intravascular ultrasound follow-up are necessary to determine the safety of this therapy. Copyright 2010 Mosby, Inc.

  19. Acute Cocaine Induces Fast Activation of D1 Receptor and Progressive Deactivation of D2 Receptor Strial Neurons: In Vivo Optical Microprobe [Ca(superscript)2+]subscript)i Imaging

    Cocaine induces fast dopamine increases in brain striatal regions, which are recognized to underlie its rewarding effects. Both dopamine D1 and D2 receptors are involved in cocaine's reward but the dynamic downstream consequences of cocaine effects in striatum are not fully understood. Here we used transgenic mice expressing EGFP under the control of either the D1 receptor (D1R) or the D2 receptor (D2R) gene and microprobe optical imaging to assess the dynamic changes in intracellular calcium ([Ca{sup 2+}]{sub i} ) responses (used as marker of neuronal activation) to acute cocaine in vivo separately for D1R- versus D2R-expressing neurons in striatum. Acute cocaine (8 mg/kg, i.p.) rapidly increased [Ca{sup 2+}]{sub i} in D1R-expressing neurons (10.6 {+-} 3.2%) in striatum within 8.3 {+-} 2.3 min after cocaine administration after which the increases plateaued; these fast [Ca{sup 2+}]{sub i} increases were blocked by pretreatment with a D1R antagonist (SCH23390). In contrast, cocaine induced progressive decreases in [Ca{sup 2+}]{sub i} in D2R-expressing neurons (10.4 {+-} 5.8%) continuously throughout the 30 min that followed cocaine administration; these slower [Ca{sup 2+}]{sub i} decreases were blocked by pretreatment with a D2R antagonist (raclopride). Since activation of striatal D1R-expressing neurons (direct-pathway) enhances cocaine reward, whereas activation of D2R expressing neurons suppresses it (indirect-pathway) (Lobo et al., 2010), this suggests that cocaine's rewarding effects entail both its fast stimulation ofD1R (resulting in abrupt activation of direct-pathway neurons) and a slower stimulation of D2R (resulting in longer-lasting deactivation of indirect-pathway neurons). We also provide direct in vivo evidence of D2R and D1R interactions in the striatal responses to acute cocaine administration.

  7. Feed safety in the feed supply chain

    Directory of Open Access Journals (Sweden)

    Pinotti, L.

    2011-01-01

    Full Text Available A number of issues have weakened the public's confidence in the quality and wholesomeness of foods of animal origin. As a result farmers, nutritionists, industry and governments have been forced to pay serious attention to animal feedstuff production processes, thereby acknowledging that animal feed safety is an essential prerequisite for human food safety. Concerns about these issues have produced a number of important effects including the ban on the use of processed animal proteins, the ban on the addition of most antimicrobials to farm animals diets for growth‐promotion purposes, and the implementation of feed contaminant regulations in the EU. In this context it is essential to integrate knowledge on feed safety and feed supply. Consequently, purchase of new and more economic sources of energy and protein in animal diets, which is expected to conform to adequate quality, traceability, environmental sustainability and safety standards, is an emerging issue in livestock production system.

  9. Indications for tube feedings in elderly patients.

    Science.gov (United States)

    Ciocon, J O

    1990-01-01

    Tube feedings are utilized in elderly patients with acute and chronic problems. Inadequate oral intake with malnutrition, comatose state, neurologic disorders with severe dysphagia, extensive burns, massive gastrointestinal resection, and oropharyngeal and upper gastrointestinal malignancies are the commonly encountered conditions requiring tube alimentation. Dysphagia with frequent aspiration is the most common indication for use of tube feedings in the elderly. Nasogastric tube is preferred for short-term feeding, while gastrostomy or jejunostomy is indicated for long-term or permanent nutritional support. Nutritional assessment should be done initially and on a regular basis. Specific formulas are available to calculate height, weight, and caloric needs of bedbound elderly patients. Various enteral feeding formulas are available for a specific clinical condition and are preferably administered by continuous drip using a pump. Parenteral nutrition is also indicated for certain situations in which enteral feeding cannot meet the patient's nutritional requirement, and in particular situations where enteral feeding is contraindicated and not feasible. Optimal patient care is dependent on adequate nutritional support.

  10. Systematic review: outpatient management of acute uncomplicated diverticulitis.

    Science.gov (United States)

    Jackson, J D; Hammond, T

    2014-07-01

    Acute uncomplicated diverticulitis is traditionally managed by inpatient admission for bowel rest, intravenous fluids and intravenous antibiotics. In recent years, an increasing number of publications have sought to determine whether care might instead be conducted in the community, with earlier enteral feeding and oral antibiotics. This systematic review evaluates the safety and efficacy of such an ambulatory approach. Medline, Embase and Cochrane Library databases were searched. All peer-reviewed studies that investigated the role of ambulatory treatment protocols for acute uncomplicated diverticulitis, either directly or indirectly, were eligible for inclusion. Nine studies were identified as being suitable for inclusion, including one randomised controlled trial, seven prospective cohort studies and one retrospective cohort study. All, except one, employed imaging as part of their diagnostic criteria. There was inconsistency between studies with regards to whether patients with significant co-morbidities were eligible for ambulatory care and whether bowel rest therapy was employed. Neither of these variables influenced outcome. Across all studies, 403 out of a total of 415 (97 %) participants were successfully treated for an episode of acute uncomplicated diverticulitis using an outpatient-type approach. Cost savings ranged from 35.0 to 83.0 %. Current evidence suggests that a more progressive, ambulatory-based approach to the majority of cases of acute uncomplicated diverticulitis is justified. Based on this evidence, the authors present a possible outpatient-based treatment algorithm. An appropriately powered randomised controlled trial is now required to determine its safety and efficacy compared to traditional inpatient management.

  15. Urban Bird Feeding: Connecting People with Nature.

    Cox, Daniel T C; Gaston, Kevin J

    2016-01-01

    At a time of unprecedented biodiversity loss, researchers are increasingly recognizing the broad range of benefits provided to humankind by nature. However, as people live more urbanized lifestyles there is a progressive disengagement with the natural world that diminishes these benefits and discourages positive environmental behaviour. The provision of food for garden birds is an increasing global phenomenon, and provides a readily accessible way for people to counter this trend. Yet despite its popularity, quite why people feed birds remains poorly understood. We explore three loosely defined motivations behind bird feeding: that it provides psychological benefits, is due to a concern about bird welfare, and/or is due to a more general orientation towards nature. We quantitatively surveyed households from urban towns in southern England to explore attitudes and actions towards garden bird feeding. Each household scored three Likert statements relating to each of the three motivations. We found that people who fed birds regularly felt more relaxed and connected to nature when they watched garden birds, and perceived that bird feeding is beneficial for bird welfare while investing time in minimising associated risks. Finally, feeding birds may be an expression of a wider orientation towards nature. Overall, we found that the feelings of being relaxed and connected to nature were the strongest drivers. As urban expansion continues both to threaten species conservation and to change peoples' relationship with the natural world, feeding birds may provide an important tool for engaging people with nature to the benefit of both people and conservation.

    de Boer, A S; Darnton-Hill, I

    1994-01-01

    The World Health Organization (WHO) and UNICEF introduced the Baby- Friendly Hospital Initiative in 1992 to foster breast feeding in hospitals. The balanced composition of breast milk fulfills the 4-6 month old infant's nutrient requirements. Colostrum is rich in antibodies and immunoglobulins, which protect the newborn against infection. As economic development progresses, more mothers use infant formulas while fewer mothers breast feed. Between 1960 and 1985 in Japan, the proportion of mothers breast feeding 1-2 month old infants fell from 68% to 50%. Between 1975 and 1968 in Western Samoa, it fell from 69% to 48% in urban areas and 78% to 59% in rural areas. Hospital practices that discourage breast feeding include separation of mother and newborn, prelacteal feedings, and free samples of infant formula. These practices occur even in areas, such as the Western Pacific Region, where most mothers deliver at home. Hospital baby-friendly criteria include a written breast-feeding policy, training of all health care staff in skills needed to implement this policy, informing all pregnant women about the benefits and management of breast feeding, assisting mothers to begin breast feeding within 30 minutes of delivery, demonstrating to mothers how to breast feed and to maintain lactation, no prelacteal feeds, newborn rooming-in with mother, promoting breast feeding on demand, no artificial teats or pacifiers, and breast-feeding support groups. The Western Pacific Region supports the Baby-Friendly Hospital Initiative. Between March 1991 and March 1993, the number of baby-friendly hospitals in the Philippines rose from 4 to 103. Dr. Jose Fabella Memorial Hospital in Manila is a model baby-friendly hospital for other hospitals in the region. It does not release mothers until milk flow has been established. By late 1992, 21 Chinese hospitals were baby-friendly. The WHO Western Pacific Region distributes information about breast feeding and the Initiative and provides breast

    Full Text Available Many people have led to the consumption of organic animal products in the event that the increase in sensitivity to a healthy diet in developed countries, and maintaining the safety of food of animal origin. Feeding and breeding in conventional production are emerged some of the negative effects and also it is more in organic production with new restrictions. Organic production is based on animal welfare. On the basis of behaviors such as feather-pecking and cannibalism known to be low in protein level of rations and unbalanced in terms of amino acids or minerals. As of 2015, organic poultry feed provided the appropriate conditions that will be 95% organic certified in Turkey and therefore, to create a balanced ration and feed hygiene in protecting brings serious challenges. Fodder supply of organic poultry feed raw materials that make up the quality, quantity and issue forms a significant effect on the health of the poultry additives permitted. The quality of the feed raw materials that constituent diets, quantity, feed supplying form and permitted feed additives significantly affects the health of poultry. Different physiological stages of the animal's nutritional requirements in order to ensure production of quality poultry products must be met from organically produced and very well-known with the contents of feedstuff digestibility. In this study, the problems encountered in feeding can be eliminated while performing economic production with considering animal welfare, following that balanced and adequate organic ration formulations and issues such as improving the production of feed raw materials are discussed.

  5. Acute Liver Failure.

    2016-12-01

    Pediatric acute liver failure (ALF) is a complex and rapidly progressive syndrome that results from a variety of age-dependent etiologies. It is defined by the acute onset of liver disease with no evidence of chronic liver disease. There must be biochemical or clinical evidence of severe liver dysfunction as defined by an international normalized ratio (INR) ≥2. If hepatic encephalopathy is present, INR should be ≥1.5. Unfortunately, due to the rarity of ALF in pediatric patients, there is a paucity of diagnostic and management algorithms and each patient must have an individualized approach.

    Both cholesterol and triglyceride levels in serum increase progressively during pregnancy. Hypertriglyceridemia is a well-recognized cause of acute pancreatitis, while pancreatitis-associated chylous ascites has rarely been reported. We report a 28-year-old female with coexistence of hypertriglyceridemia, acute pancreatitis, and chylous ascites during pregnancy. After emergency cesarean section, she was treated with nil per os, intravenous hydration, antibiotics, and analgesics as required. Due to the development of positive peritonitis 5 days later, an exploratory laparotomy was performed.

    2006-01-01

    Full Text Available Both cholesterol and triglyceride levels in serum increase progressively during pregnancy. Hypertrigly-ceridemia is a well-recognized cause of acute pancreatitis, while pancreatitis-associated chylous ascites has rarely been reported. We report a 28-year-old female with coexistence of hypertriglyceridemia, acute pancreatitis, and chylous ascites during pregnancy. After emergency cesarean section, she was treated with nil per os, intravenous hydration, antibiotics, and analgesics as required. Due to the development of positive peritonitis 5 days later, an exploratory laparotomy was performed. Surgical interventions included pancreatic necrosec-tomy, right hemicolectomy and ileostomy, cholecystostomy, gastrostomy, and feeding jejunostomy. Postoperative treatment included antibiotics, total parenteral nutrition, and then low-fat diet with medium-chain triglyceride supplementation. She was discharged on the 43rd day after surgery and was free of symptoms during 6 months of follow-up. Ileocolostomy was performed 6 months after discharge. Fasting lipid profile should be regularly monitored during pregnancy due to the association of hypertriglyceridemia with development of acute pancreatitis in the mother.

    Full Text Available The contamination of foods and feeds is a significant problem in worldwide. Mycotoxins are secondary metabolites of fungi, particularly by many species of Aspergillus, Fusarium, Penicillium, Claviceps and Alternaria in many agricultural crops, especially in cereals and most oilseeds. Aflatoxins, ochratoxins, trichothecenes, zearelenone and fumonisins are the mycotoxins of greatest agro-economic importance. Mycotoxins have various acute and chronic effects on animals (especially monogastrics depending on species and susceptibility of an animal within a species. The most applied method to prevent mycotoxicosis in animals involves the addition to the diet of additives with the ability to bind or metabolize mycotoxin in the gastrointestinal digesta, aluminosilicates, activated charcoal, yeast and several polymers have been tested regarding the adsorption of mycotoxins in the gastrointestinal tract of different species. The efficiency of mycotoxin binders, however, differs considerably depending mainly on the chemical structure of both the adsorbent and the toxin. This review describes the most implications of mycotoxins in livestock feeds.

    1981-01-01

    Purpose: To control the dissolved oxygen concentration in water of a condensate feeding system to a desired level. Constitution: Coolant is fed to a nuclear reactor through a route from the steam exit of the reactor and by way of turbine, turbine condensator, condensate pump, condensate desalinator, feedwater heater and feed pump. Steam extraction lines are branched from the turbines, and pipeways are further branched from the steam extraction lines for feeding steam by way of extraction steam injection valves to steam-water mixers disposed on the upstream of the feedwater heater. On the downstream of the feedwater heater, is provided a dissolved oxygen concentration meter, the indication value of which controls the opening degree of the steam injection valves which, in turn, controls the opening degree of the steam feed valves for the feedwater heater to adjust the amount for the injection steams. Accordingly, the dissolved oxygen concentration in the water of the condensate feeding system can be controlled by the inclusion of steams with high dissolved oxygen concentration into the feedwater system from the turbine steam extraction lines by way of the mixers.

    Cannabis is a drug derived from hemp plant, Cannabis sativa, used both as a recreational drug or as medicine. It is a widespread illegal substance, generally smoked for its hallucinogenic properties. Little is known about the adverse effects of postnatal cannabis exposure throw breast feeding because of a lack of studies in lactating women. The active substance of cannabis is the delta 9 Tetrahydrocannabinol (THC). Some studies conclude that it could decrease motor development of the child at one year of age. Therefore, cannabis use and abuse of other drugs like alcohol, tobacco, or cocaine must be contraindicated during breast feeding. Mothers who use cannabis must stop breast feeding, or ask for medical assistance to stop cannabis use in order to provide her baby with all the benefits of human milk.

  10. Xanthophylls in Poultry Feeding

    Breithaupt, Diemar R.

    Since most consumers associate an intense colour of food with healthy animals and high food quality, xanthophylls are widely used as feed additives to generate products that meet consumers' demands. An important large-scale application is in poultry farming, where xanthophylls are added to feed to give the golden colour of egg yolk that is so much appreciated. Now, with numerous new applications in human food, in the pharmaceutical industry, and in cosmetic products, there is an increasing demand for xanthophylls on the international market (Volume 5, Chapter 4).

  11. Magnetic resonance imaging for acute pancreatitis.

    Science.gov (United States)

    Xiao, Bo; Zhang, Xiao-Ming

    2010-08-28

    Acute pancreatitis is characterized by acute chemical injury of the pancreatic parenchyma and peripancreatic tissue. The increased frequency of death in acute pancreatitis is directly correlated with the degree and progress of pancreatic necrosis. Moreover, the occurrence of some local complications in acute pancreatitis, such as pancreatic hemorrhage, peripancreatic abscess or large pseudocyst, and pseudoaneurysm, could influence the choice of treatment for these patients. Magnetic resonance imaging (MRI) can be used to help evaluate the presence and degree of pancreatic necrosis, and is crucial for identifying complications of acute pancreatitis and predicting prognosis. The purpose of this article is to describe MRI techniques for acute pancreatitis, to review the spectrum of pancreatic and peripancreatic patterns, as well as to survey various complications secondary to acute pancreatitis on MRI. The role of MRI in the initial evaluation and staging of acute pancreatitis is emphasized.

  13. Progressivity Enhanced

    Directory of Open Access Journals (Sweden)

    2013-09-01

    Full Text Available Rather than a scientific text, the author contributes a concise memorandum from the originator of the idea who has managed the campaign for the conversion of the military barracks into a creative cluster between 1988 and 2002, when he parted ways with Metelkova due to conflicting views on the center’s future. His views shed light on a distant period of time from a perspective of a participant–observer. The information is abundantly supported by primary sources, also available online. However, some of the presented hypotheses are heavily influenced by his personal experiences of xenophobia, elitism, and predatorial behavior, which were already then discernible on the so-called alternative scene as well – so much so that they obstructed the implementation of progressive programs. The author claims that, in spite of the substantially different reality today, the myths and prejudices concerning Metelkova must be done away with in order to enhance its progressive nature. Above all, the paper calls for an objective view on internal antagonisms, mainly originating in deep class divisions between the users. These make a clear distinction between truly marginal ndividuals and the overambitious beau-bourgeois, as the author labels the large part of users of Metelkova of »his« time. On these grounds, he argues for a robust approach to ban all forms of xenophobia and self-ghettoization.

    2013-03-01

    This prospective, observational study examined the accuracy of modular feed preparation for children with complex medical conditions requiring specialist feeds. Participants who regularly prepare special feeds at home were observed preparing two feeds with equivalent nutrient composition: a 2-ingredient (2-IF) and 6-ingredient feed (6-IF) under research-conditions, and 8 weeks later under home-conditions. The same feeds (2-IF and 6-IF) prepared by a trained feed-maker served as controls. Biochemical analysis of nutrient content was performed as an objective measure of feed preparation accuracy. 52 participants were studied: one patient and 51 caregivers. Biochemical nutrient analysis was inaccurate for both feeds including control-feeds but was better for the 2-IF. Both feeds were lower in fat than the expected calculation but more so in the 6-IF than the 2-IF (median: 34% vs 84% of calculated research-condition values and 66% vs 90% home-conditions; pfeeds there was equipment inaccuracy, poor ingredient emulsification and ingredient residue left in mixing/measuring containers. Fewer errors occurred with powdered than liquid ingredients. Many errors associated with special feed production are difficult to control. Carers of children with complex medical conditions require improved preparation equipment and techniques and the development of premeasured or combined ingredient preparations to maximise feed accuracy and minimise clinical risk.

  8. Modulation of SF1 Neuron Activity Coordinately Regulates Both Feeding Behavior and Associated Emotional States

    Directory of Open Access Journals (Sweden)

    Paulius Viskaitis

    2017-12-01

    Full Text Available Feeding requires the integration of homeostatic drives with emotional states relevant to food procurement in potentially hostile environments. The ventromedial hypothalamus (VMH regulates feeding and anxiety, but how these are controlled in a concerted manner remains unclear. Using pharmacogenetic, optogenetic, and calcium imaging approaches with a battery of behavioral assays, we demonstrate that VMH steroidogenic factor 1 (SF1 neurons constitute a nutritionally sensitive switch, modulating the competing motivations of feeding and avoidance of potentially dangerous environments. Acute alteration of SF1 neuronal activity alters food intake via changes in appetite and feeding-related behaviors, including locomotion, exploration, anxiety, and valence. In turn, intrinsic SF1 neuron activity is low during feeding and increases with both feeding termination and stress. Our findings identify SF1 neurons as a key part of the neurocircuitry that controls both feeding and related affective states, giving potential insights into the relationship between disordered eating and stress-associated psychological disorders in humans.

    2017-04-01

    Effective utilization of available feed resources is the key for economical livestock rearing. Complete feed system is one of the latest developments to exploit the potential of animal feed resources in the best possible way. The complete feed is a quantitative mixture of all dietary ingredients, blended thoroughly to prevent separation and selection, fed as a sole source of nutrients except water and is formulated in a desired proportion to meet the specific nutrient requirements. The concentrate and roughage levels may vary according to the nutrient requirement of ruminants for different production purposes. The complete feed with the use of fibrous crop residue is a noble way to increase the voluntary feed intake and thus animal's production performance. In this system of feeding, the ruminant animals have continuous free choice availability of uniform feed mixture, resulting in more uniform load on the rumen and less fluctuation in release of ammonia which supports more efficient utilization of ruminal non-protein nitrogen. Feeding complete diet stabilizes ruminal fermentation, thereby improves nutrient utilization. This feeding system allows expanded use of agro-industrial by-products, crop residues and nonconventional feeds in ruminant ration for maximizing production and minimizing feeding cost, thus being increasingly appreciated. However, to extend the concept extensively to the field and make this technology successful and viable for farmers, more efforts are needed to be taken.

    2013-01-01

    To examine the effect of initiating very early feeding on time-to-reach full feeding in stable, small for gestational age (SGA) preterm infants. Preterm infants with gestational age below 37 weeks and birth weight below the 10(th) percentile were randomly allocated to a very early (within 24 hours of birth) feeding regimen or delayed (after 24 hours of birth) feeding. All infants had in utero evidence of absent or reverse diastolic flow. Infants unable to start early feeding were excluded. Time-to-reach full feeding, feeding progression, and related morbidity were compared. Electrogastrography (EGG) was used to measure pre- and postprandial gastric motility on the second and seventh day after feeding initiation. Sixty infants were included in the study, 30 in each group. Infants included in the very early feeding regimen achieved full enteral feeding sooner than controls (98±80-157 vs. 172±123-261 hours of age, respectively; p= 0.004) and were discharged home earlier (p=0.04). No necrotizing enterocolitis (NEC) was documented in both study groups. Gastric motility was improved at day seven after feeding initiation in both study groups, with no difference between groups. Stable SGA preterm infants on a very early feeding regimen achieved full enteral feeding and were discharged home significantly earlier than those on a delayed regimen, with no excess morbidity.

    Production of food has re-emerged at the top of the global political agenda, driven by two contemporary challenges: the challenge to produce enough nutritious food to feed a growing and more prosperous human population, and the challenge to produce this food in an environmentally sustainable way. Current levels of production of especially animal-source food (ASF), pose severe pressure on the environment via their emissions to air, water, and soil; and their use of scarce resources, such as la...

    Enteral feeding is considered a widespread, well-accepted means of delivering nutrition to adults and children who are unable to consume food by mouth or who need support in maintaining adequate nutrition for a variety of reasons, including acute and chronic disease states. Delivery of enteral feeding to nutritionally deprived patients may be achieved by several means. In this article, the indications and insertion of enteral access in children will be reviewed. In addition, common complications and management of problems will be discussed.

    Full Text Available In recent decades there has been substantial progress in the technology of premature infants nursing, especially with extremely low birth weight. Adequate feeding is one of the fundamental factors of premature babies nursing. To ensure a premature baby with all necessary components for power saving in breast milk intake, breast milk fortifiers — specifically developed additives that adjust the composition of food for premature babies, are used for more than 20 years (for premature babies receiving breast milk. On the one hand, to preserve all benefits of breastfeeding, on the other — to prevent the deficit development of necessary elements for adequate growth and development of nutrients.

    Syringomyelia is generally regarded as a chronic, slowly progressive disorder. We describe a case of acute dilation of the central canal of the spinal cord that presented with rapidly progressive segmental signs. A 29-year-old female patient who had previously undergone surgical treatment for a Chiari I malformation, syringomyelia, and hydrocephalus presented with an 8-day history of headaches, progressive paraparesis, and urinary retention. Magnetic resonance imaging scans demonstrated panventricular hydrocephalus in association with a holocord syrinx that extended to the obex. Magnetic resonance imaging scans that had been coincidentally obtained just 3 days before the onset of symptoms had revealed no evidence of hydrocephalus or syringomyelia. The patient underwent emergency revision of a failed ventriculoperitoneal shunt. Postoperatively, there was prompt resolution of the syringomyelia, hydrocephalus, and associated neurological deficits. Among patients with communicating syringomyelia, the central canal of the spinal cord participates as a "fifth ventricle" and can undergo rapid dilation in association with acute hydrocephalus. Appropriate treatment in such cases involves placement of a ventriculoperitoneal shunt.

    Full Text Available The acute-phase response (APR is a prominent systemic reaction of the organism to local or systemic disturbances in its homeostasis caused by infection, tissue injury, trauma or surgery, or immunological disorders. The tissue macrophage is most commonly regarded as initiating the APR through direct stimulation and secretion of various cell communicating factors. Proinflammatory cytokines and mediators are significantly elevated with gingival inflammation and during the destructive phase of periodontitis. Cytokines appear to play a major role in the clinical symptoms and tissue destruction associated with progressing periodontitis. Many of these cytokines are derived from activated macrophages and can act both locally and distally to amplify cytokine production from other cell types. The host responses to periodontal disease and cardiovascular diseases were reflected by an increase in the acute-phase proteins (serum amyloid A and C-reactive protein.

    Full Text Available This review presents current data on the mechanism of action, selective toxicity, toxicokinetics and toxicodynamics of diacetylmorphine (heroin. Acute diacetylmorphine poisoning is considered under taking into account the developing a critical state, in which the poisoning severity is determined by severe metabolic disorders associated with the progression of hypoxia. The main lifethreatening complications of acute diacetyl morphine poisoning are described including those associated with the nervous system, respiratory, circulatory and urinary systems. Since hypoxia is the principal damaging factor, the the mechanisms of oxygen transport disorders and the pathogenesis of activation of free radical oxidation in acute diacetylmorphine poisoning are discussed. The improvement of intensive care strategy for severe forms of acute diacetylmorphine poisoning by the inclusion of a substrate antihypoxant Reamberin into the list of routine critical care prescriptions is emphesized.

  10. Radiation pasteurization of poultry feed: Preliminary results of feeding tests

    1992-01-01

    Feed used to rear farm animals for human consumption has often been implicated as a vehicle for dissemination of microbial pathogens that can adversely affect both animals or birds, and humans. Radiation pasteurization of animal feed to improve its microbiological quality should reduce the incidence of feed-borne infection in the herd or flock. This would result in safer food for the consumer, and improved economic performance of the production unit. This latter benefit is particularly important because it would directly offset the cost of treating the feed. The likelihood of occurrence, as well as the magnitude, of any improved economic performance in the herd or flock consuming the irradiated feed must be determined experimentally. Accordingly, short term feeding tests were carried out to determine the effect of radiation pasteurization of poultry feed on growth performance of young chicks. The results suggest that radiation pasteurization of poultry feed may have a beneficial effect on the feed conversion efficiency of the birds consuming that feed. 10 refs, 8 tabs

    Radiodiagnosis is applied to determine the causes of acute dyspnea. Acute dyspnea is shown to aggravate the course of pulmonary diseases (bronchial asthma, obstructive bronchitis, pulmonary edema, throboembolism of pulmonary arteries etc) and cardiovascular diseases (desiseas of myocardium). The main tasks of radiodiagnosis are to determine volume and state of the lungs, localization and type of pulmonary injuries, to verify heart disease and to reveal concomitant complications

    Identification of neuroprotective therapies in acute ischemic stroke is imperative. We report a predefined analysis of the URICO-ICTUS trial (Efficacy Study of Combined Treatment With Uric Acid and r-tPA in Acute Ischemic Stroke) assessing the efficacy of uric acid (UA) compared with placebo to prevent early ischemic worsening (EIW) and the relevance of collateral circulation. URICO-ICTUS was a double-blind, placebo-controlled, phase 2b trial where a total of 411 patients treated with alteplase within 4.5 hours of stroke onset were randomized (1:1) to receive UA 1000 mg (n=211) or placebo (n=200) before the end of alteplase infusion. EIW defined an increment ≥4 points in the National Institutes of Health Stroke Scale score within 72 hours of treatment in the absence of hemorrhage or recurrent stroke. Logistic regression models assessed the interaction between therapy and the collateral circulation in 112 patients who had a pretreatment computed tomographic angiography. EIW occurred in 2 of 149 (1%) patients with good outcome and 23 of 262 (9%) patients with poor outcome (χ 2 ; P=0.002). EIW occurred in 7 of 204 (3%) patients treated with UA and in 18 of 200 (9%) patients treated with placebo (χ 2 ; P=0.01). There was a significant interaction between the efficacy of UA to prevent EIW and collaterals (P=0.029), with lower incidence in patients with good collaterals treated with UA compared with placebo (2% versus 15%, respectively; P=0.048). UA therapy may prevent EIW after acute stroke in thrombolysed patients. Optimal access of UA to its molecular targets through appropriate collaterals may modify the magnitude of the neuroprotective effect. URL: http://www.clinicaltrials.gov.

  14. Motivation of hens to obtain feed during a molt induced by feed withdrawal, wheat middlings, or melengestrol acetate.

    Traditionally, molting was initiated by withdrawing feed. However, public criticism of feed deprivation, based on the perception that it inhumanely increases hunger, has led the poultry industry to ban the practice. Thus far, alternatives have not been demonstrated to ameliorate the increase in hunger that led to the ban on inducing molting by feed deprivation. Incorporating melengestrol acetate (MGA), an orally active progestin, into a balanced layer diet induces molting and increases postmolt egg quality. Hy-Line W-98 hens (n = 60) were randomly assigned to a balanced layer ration (control), a balanced layer ration containing MGA, or a 94% wheat middlings diet (wheat) for 20 d, or were feed deprived for 8 d. Hens were trained to peck a switch to receive a feed reward based on a progressive ratio reinforcement schedule. Motivation of hens to acquire feed was measured as the total number of pecks recorded in 15 min on d 0, 4, 8, 12, 16, and 20. On d 20, abdominal fat pad and digesta-free gizzards were weighed. The number of pecks in the feed-deprived group was greater than controls by d 4 and remained greater at d 8, when these hens were removed from the experiment. Hens in the wheat group that were rewarded with a layer diet pecked more than controls from d 8 to 20. Hens in the MGA group pecked for a reward at the same rate as control hens throughout the experiment. Hens fed the wheat diet had heavier gizzards compared with control and MGA-fed hens. Hens fed MGA had greater abdominal fat pad compared with wheat and control hens. Hens molted using a diet containing MGA have a similar motivation to obtain feed as control hens; therefore, this alternative does not appear to increase hunger. However, hens molted with a wheat middling diet appear to be as motivated to obtain feed as did the feed-deprived hens.

    Mitral regurgitation (MR) is a frequent valve disorder in elderly patients, often accompanied by multiple comorbidities such as renal impairment. In these patients percutaneous mitral valve (MV) repair has become an established treatment option but the role of MR on renal dysfunction is not yet well defined. We here report on two cases presenting with severe MR and progressive renal failure caused by cardio renal syndrome, in which percutaneous MV treatment with the MitraClip system significantly improved renal function. These findings suggest that interventional MV repair can prevent progression of renal deterioration in patients suffering from combined advanced heart and renal failure. Further clinical studies are necessary to support our finding and to answer the question whether optimizing renal function by implantation of the MitraClip device is also of prognostic relevance in these patients. © 2014 Wiley Periodicals, Inc.

    An antenna may include a volume polarization current radiator and a feed network. The volume polarization current radiator, includes a dielectric solid (such as a dielectric strip), and a plurality of closely-spaced excitation elements (24), each excitation element (24) being configured to induce a volume polarization current distribution in the dielectric solid proximate to the excitation element when a voltage is applied to the excitation element. The feed network is coupled to the volume polarization current radiator. The feed network also includes a plurality of passive power divider elements (32) and a plurality of passive delay elements (d1-d6) coupling the first port (30) and the plurality of second ports (108, 109, 164), the plurality of power divider elements (32) and the plurality of phase delay elements (d1-d6) being configured such that a radio-frequency signal that is applied to the first port (30) experiences a progressive change of phase as it is coupled to the plurality of second ports (108, 109, 164) so as to cause the volume polarization current distribution to propagate along the dielectric solid.

    Severe acute pancreatitis poses unique nutritional challenges. The optimal nutritional support in patients with severe acute pancreatitis has been a subject of debate for decades. This review provides a critical review of the available literature. According to current literature, enteral nutrition is superior to parenteral nutrition, although several limitations should be taken into account. The optimal route of enteral nutrition remains unclear, but normal or nasogastric tube feeding seems safe when tolerated. In patients with predicted severe acute pancreatitis an on-demand feeding strategy is advised and when patients do not tolerate an oral diet after 72 hours, enteral nutrition can be started. The use of supplements, both parenteral as enteral, are not recommended. Optimal nutritional support in severe cases often requires a tailor-made approach with day-to-day evaluation of its effectiveness.

  19. Oxytocin, feeding and satiety

    Full Text Available Oxytocin neurones have a physiological role in food intake and energy balance. Central administration of oxytocin is powerfully anorexigenic, reducing food intake and meal duration. The central mechanisms underlying this effect of oxytocin have become better understood in the past few years. Parvocellular neurones of the paraventricular nucleus project to the caudal brainstem to regulate feeding via autonomic functions including the gastrointestinal vago-vagal reflex. In contrast, magnocellular neurones of the supraoptic and paraventricular nuclei release oxytocin from their dendrites to diffuse to distant hypothalamic targets involved in satiety.The ventromedial hypothalamus, for example, expresses a high density of oxytocin receptors but does not contain detectable oxytocin nerve fibres. Magnocellular neurones represent targets for the anorexigenic neuropeptide α-melanocyte stimulating hormone. . In addition to homeostatic control, oxytocin may also have a role in reward-related feeding. Evidence suggests that oxytocin can selectively suppress sugar intake and that it may have a role in limiting the intake of palatable food by inhibiting the reward pathway.

    In this study breeders and owners of 8 different dog breeds (Beagle, Bernese Mountain Dog, Cavalier King Charles Spaniel, Great Dane, German Shepherd (GS), Labrador, Papillon, Sheltie) were interviewed to obtain information on puppy feeding in Switzerland. Besides answering a questionnaire (husbandry and feeding of the puppies), the participation in this study included weekly weighing of the animals as well as exact documentation of the amount fed to the animals. Totally 67 dog breeders and 131 new owners of puppies participated. The weight development of the puppies was mostly parallel to the growth curve in the GS, Labradors and Shelties. There were some substantial differences to the ideal growth curve within the other breeds. The daily mean energy requirement was estimated too high, when including the growth curves. 80 - 90 % of the recommendations would be sufficient for most animals. The calcium supply was in the range of tolerance in all breeds. Nearly all breeders used commercially available complete food while raising the puppies. No breed-specific differences could be shown.

    Recurrent acute pancreatitis (RAP) is a challenging condition that can lead to chronic pancreatitis and long-term morbidity. Etiology-based treatment can potentially have an impact on the natural history of RAP and its progression to chronic pancreatitis. In cases of divisum-associated RAP and idiopathic RAP, several studies have been performed to evaluate the efficacy of endoscopic therapy in alleviation of symptoms and frequency of AP events. This review discusses the literature available on these topic as well as touching on the role of endoscopic therapy in smoldering acute pancreatitis. Published by Elsevier Inc.

    Shaping up the post-2015 development agenda is of crucial importance in the development process around the Globe as 2015 was the last year of milllionium development goals. It is the right time to asses our own progress vis-a-vis the Millennium Development Goals and these Guidelines are an attempt in that regard. The Infant and Young Child Feeding (IYCF) chapter of Indian Academy of Pediatrics invited a group of experts for National Consultative Meet for discussing and contributing on latest scientific advances and developments. Various partners from WHO, UNICEF, Ministry of Child Welfare Department, Ministry of Health and Family Welfare, Ministry of Chemical and Fertilizers of Govt of India, Human Milk Banking Association (of India), Indian Medico-Legal and Ethics Association (IMLEA), non-governmental organizations and academicians from various states of India contributed to these guidelines. The guidelines were finalized during the IYCNCON 2015 at New Delhi in August 2015. To formulate, endorse, adopt and disseminate guidelines related to Infant and Young Child feeding from an Indian perspective (including human milk banking, infant feeding in the HIV situation, and micro-nutrients). Early initiation of breastfeeding within first hour of birth, exclusive breastfeeding for the first six months followed by continued breastfeeding for up to two years and beyond with appropriate complementary foods after completion of 6 months is the most appropriate feeding strategy. Micro-nutrient supplementation in infants, and adequate nutrition and anemia control for adolescent girls, pregnant and lactating mothers is advocated. Concepts and need for human milk banks in India has also been incorporated.

    This study examined how early exposure to different feed presentations affects development of feed sorting in dairy calves. Twenty Holstein bull calves were exposed for the first 8 wk of life to 1 of 2 feed presentation treatments: concentrate and chopped grass hay (Calves received 8L/d of milk replacer (1.2kg of dry matter), with the amount progressively reduced after 5 wk to facilitate weaning by the end of wk 7. All calves received the MIX diet in wk 9 to 11 and, subsequently, a novel total mixed ration (TMR; containing 40.5% corn silage, 22.0% haylage, 21.5% high-moisture corn, and 16.0% protein supplement) in wk 12 to 13. Intake was recorded daily and calves were weighed twice a week. Fresh feed and orts were sampled on d 1 to 4 of wk 6, 8, 9, 11, 12, and 13 for analysis of feed sorting, which was assessed through nutrient analysis for the MIX diet and particle size analysis for the TMR. The particle separator had 3 screens (19, 8, and 1.18mm) producing long, medium, short, and fine particle fractions. Sorting of nutrients or particle fractions was calculated as the actual intake as a percentage of predicted intake; values >100% indicate sorting for, whereas values Feed presentation did not affect dry matter intake or growth. Prior to weaning, all calves selected in favor of hay; MIX calves consumed more neutral detergent fiber (NDF) than predicted (103.6%) and less nonfiber carbohydrates (NFC) than predicted (92.6%), and COM calves consumed, as a percentage of dry matter intake, 40.3% hay (vs. 30% offered rate). In wk 8, calves fed COM consumed more NFC than calves fed MIX (1.0 vs. 0.95kg/d) and less NDF (0.43 vs. 0.54kg/d), indicating greater selection in favor of concentrate. However, when provided the MIX diet, calves previously fed COM did not sort, whereas calves previously fed MIX consumed more NFC intake than predicted (103.2%) and less NDF intake than predicted (97.6%). Calves previously fed MIX maintained increased sorting after transition to the

    OBJECTIVE: All forms of commonly practiced enteral feeding techniques stimulate pancreatic secretion, and only intravenous feeding avoids it. In this study, we explored the possibility of more distal enteral infusions of tube feeds to see whether activation of the ileal brake mechanism can result...... in plasma glucagon-like peptide-1 and peptide YY concentrations. CONCLUSIONS: Our results suggest that enteral feeding can be given without stimulating pancreatic trypsin secretion provided it is delivered into the mid-distal jejunum. The mechanism may involve activation of the ileal brake mechanism....

    1977-04-01

    The incidence of breastfeeding is investigated in relation to duration of breastfeeding without supplementation and the age when solids were first introduced in the infant's diet. The study also evaluates the awareness of the mothers of the benefits of breast milk. 461 mothers were interviewed in May 1976 by 3 doctors including the author. 95% (438) were found to breastfeed their babies at least once or twice a day. However, only 18% (86) of the mothers were fully breastfeeding up to 3 months and 9% (45) were breastfeeding without added solids up to 6 months. A disappointing finding was the introduction of solid foods by 78% (351) of the mothers before the end of the 3rd month; of these, 117 or 25% have introduced the solids as early as the 1st 6 months. Only 5% (23) were artificially feeding their infants. 86% (399) agreed that breast milk was the best milk for their children but only 277 (59%) agreed that infection occurs less frequently in breastfed than bottlefed children. 65% (302) were aware that solids should be introduced after 6 months to the infant's diet. Only 48% (222) were aware that a well-balanced diet is essential for an adequate supply of breast milk. Although 50% (232) reported that they were advised by nurses or bidans to breastfeed their children, only 37% (172) were given instructions on the technique of breastfeeding. Breastfeeding programs launched by the Ministry of Health should promote breastfeeding for at least 4-6 months duration and discourage early complement feeding and introduction of solids to infants less than 6 months of age.

    Stevens, Emily E; Patrick, Thelma E; Pickler, Rita

    2009-01-01

    The historical evolution of infant feeding includes wet nursing, the feeding bottle, and formula use. Before the invention of bottles and formula, wet nursing was the safest and most common alternative to the natural mother's breastmilk. Society's negative view of wet nursing, combined with improvements of the feeding bottle, the availability of animal's milk, and advances in formula development, gradually led to the substitution of artificial feeding for wet nursing. In addition, the advertising and safety of formula products increased their popularity and use among society. Currently, infant formula-feeding is widely practiced in the United States and appears to contribute to the development of several common childhood illnesses, including atopy, diabetes mellitus, and childhood obesity.

    2011-01-01

    Acute viral bronchiolitis represents the most common lower respiratory tract infection in infants and young children and is associated with substantial morbidity and mortality. Respiratory syncytial virus is the most frequently identified virus, but many other viruses may also cause acute bronchiolitis. There is no common definition of acute viral bronchiolitis used internationally, and this may explain part of the confusion in the literature. Most children with bronchiolitis have a self limiting mild disease and can be safely managed at home with careful attention to feeding and respiratory status. Criteria for referral and admission vary between hospitals as do clinical practice in the management of acute viral bronchiolitis, and there is confusion and lack of evidence over the best treatment for this condition. Supportive care, including administration of oxygen and fluids, is the cornerstone of current treatment. The majority of infants and children with bronchiolitis do not require specific measures. Bronchodilators should not be routinely used in the management of acute viral bronchiolitis, but may be effective in some patients. Most of the commonly used management modalities have not been shown to have a clear beneficial effect on the course of the disease. For example, inhaled and systemic corticosteroids, leukotriene receptor antagonists, immunoglobulins and monoclonal antibodies, antibiotics, antiviral therapy, and chest physiotherapy should not be used routinely in the management of bronchiolitis. The potential effect of hypertonic saline on the course of the acute disease is promising, but further studies are required. In critically ill children with bronchiolitis, today there is little justification for the use of surfactant and heliox. Nasal continuous positive airway pressure may be beneficial in children with severe bronchiolitis but a large trial is needed to determine its value. Finally, very little is known on the effect of the various

  6. Radiation pasteurization of mink feed

    No significant differences were observed in the net birth rate of mink kits/female between the 7 breeding groups. However, there was reduced incidence (P=0.05) of kit deaths among the females receiving irradiated feed, and larger kit size (P<0.0001) at birth particularly for the litter size of 5-8 kits. The second generation minks born to parents receiving feed irradiated to a planned dose of 1 kGy weighed on average about 2.5% more, and their fur was on average about 1±0.26 cm longer (12% more males making the top length grade). Moreover, there was no effect of irradiated feed on fur quality. Irradiation of mink feed with subsequent frozen storage of the meat component improved the microbiological quality by decreasing the incidence of Pseudomonas sp. and Salmonella sp. Radiation pasteurization of mink feed (frozen meat to 1 kGy, and dry feed to 2 kGy or more) should therefore help improve feed utilization, keep animals healthier, and reproducing better without affecting fur quality.

But, ironically, this type is usually less severe than posterior epistaxis, in which blood may run briskly but unseen down the throat. The choice among the many treatment methods available depends on the source and cause of epistaxis. The authors present a methodical approach to patient evaluation and describe the best therapy for various situations.

  10. Breast-feeding influences on later life--cardiovascular disease.

    Science.gov (United States)

    Leon, D A; Ronalds, G

    2009-01-01

    Current evidence, almost exclusively from observational studies, provides a rather mixed picture. From the few studies that have been able to look at fatal or non-fatal cardiovascular events, there is little indication that breast-feeding is associated with either an increased or decreased risk. With respect to blood pressure, the meta-analyses suggest a small but statistically significant lowering of around 1 mmHg SBP associated with having been breast-fed in infancy. However, there is a strong indication from the meta-analyses that even this small effect may partly be accounted for by publication bias. The strongest evidence for an effect of breast-feeding reviewed in this chapter is for serum lipids, where there is good evidence that being breast-fed is associated with an increase in serum total cholesterol in infancy. In childhood there appears to be no association, while in adults there is some indication of breast-feeding being associated with a small decline in total cholesterol levels. As already outlined at the start of the chapter, this whole area of research is made particularly difficult by the fact that breast-feeding can be defined in many different ways. Some studies use definitions that are equivalent to exclusive breast-feeding prior to weaning, while others define it as having ever been breast-fed. This problem of classification is likely to dilute any real associations that may exist. The other major problem is one of interpretation. A result implying that breast-feeding is a "good thing" for cardiovascular health could equally be construed as evidence for a "bad" effect of bottle-feeding. From these data alone, we cannot convincingly determine which conclusion is correct. This is not simply a philosophical debating point. As discussed above in relation to the interpretation of results from the randomised trial of infant feeding, the issue has implications for all research on this topic. Some progress in this area will be made if studies are

    1997-03-01

    This article discusses the unequal distribution of food within and among countries of the world, poverty as the main cause of hunger, the patterns of population growth, and future prospects. The evidence reveals the potential for reaching limits of agricultural expansion. Widespread environmental destruction suggests that agricultural lands are declining. Current production patterns may not be sustainable. "Population growth is the single largest determinant of future needs." Farmers of the world's poorest regions must produce food to meet the needs of a doubled population by 2050. The 1996 World Food Summit urged that agricultural policies emphasize environmentally sustainable production methods and a wider variety of crops that would include sorghum and millet. In the early 1990s, 40% of Africa's population was food-energy deficient. Africa has some of the highest population growth rates. Fertility stands at about 6 children/woman. Even with reduced fertility, the African population is expected to double to 22% of world population by 2050. The East Asian population, which is dominated by China, is expected to reach 2.2 billion by 2050. South Asia includes some of the poorest and most densely populated countries; its population is expected to reach 2.2-3.3 billion by 2050. 43% of the malnourished population during 1990-92 lived in sub-Saharan Africa, 22% lived in South Asia, 16% lived in East and Southeast Asia, 15% lived in Latin America and the Caribbean, and 12% lived in the Near East and North Africa. The proportions of underweight children included 58% in South Asia, 30% in sub-Saharan Africa, 25% in the Near East and North Africa, 24% in East and Southeast Asia, and 12% in Latin America and the Caribbean. If everyone adopted a vegetarian diet and no food were wasted, there would be enough food to feed 10 billion people. Malnourishment has the harshest effects on children, rural populations, the growing urban poor, and victims of natural disasters.

    Atherosclerosis is a chronic inflammatory disease of the vessel wall and a major cause of death worldwide. One of atherosclerosis’ most dreadful complications are acute coronary syndromes that comprise ST-segment elevation myocardial infarction, non-ST-segment elevation myocardial infarction, and unstable angina. We now understand that inflammation substantially contributes to the initiation, progression, and destabilization of atherosclerosis. In this review, we will focus on the role of inflammatory leukocytes, which are the cellular protagonists of vascular inflammation, in triggering disease progression and, ultimately, the destabilization that causes acute coronary syndromes.

  14. The Potential for Engineering Enhanced Functional-Feed Soybeans for Sustainable Aquaculture Feed.

    Science.gov (United States)

    Herman, Eliot M; Schmidt, Monica A

    2016-01-01

    Aquaculture is the most rapidly growing segment of global animal production that now surpasses wild-capture fisheries production and is continuing to grow 10% annually. Sustainable aquaculture needs to diminish, and progressively eliminate, its dependence on fishmeal-sourced feed from over-harvested fisheries. Sustainable aquafeed sources will need to be primarily of plant-origin. Soybean is currently the primary global vegetable-origin protein source for aquaculture. Direct exchange of soybean meal for fishmeal in aquafeed has resulted in reduced growth rates due in part to soybean's anti-nutritional proteins. To produce soybeans for use in aquaculture feeds a new conventional line has been bred termed Triple Null by stacking null alleles for the feed-relevant proteins Kunitz Trypsin Inhibitor, lectin, and P34 allergen. Triple Null is now being further enhanced as a platform to build additional transgene traits for vaccines, altered protein composition, and to produce high levels of β-carotene an intrinsic orange-colored aquafeed marker to distinguish the seeds from commodity beans and as the metabolic feedstock precursor of highly valued astaxanthin.

    2017-01-01

    Full Text Available Colloid cysts are benign slow-growing cystic lesions located on the roof of the third ventricle that usually present with symptoms related to gradual rise of intracranial pressure. They mostly remain asymptomatic and sometimes grow progressively and cause diverse symptoms associated with increased intracranial pressure such as headache, diplopia, and sixth cranial nerve palsy. Here we report a 47-year-old female who presented to the emergency department with acute severe headache and nausea/vomiting. On MRI examination acute hydrocephaly due to hemorrhagic colloid cyst was detected. Acute hemorrhage in colloid cysts is extremely rare and may present with symptoms of acute increase in the intracranial pressure. Intracystic hemorrhage is very rarely reported as a complication of colloid cyst presenting with paroxysmal symptoms of acute hydrocephaly.

    Microbial filter feeders are an important group of grazers, significant to the microbial loop, aquatic food webs, and biogeochemical cycling. Our understanding of microbial filter feeding is poor, and, importantly, it is unknown what force microbial filter feeders must generate to process adequate...... amounts of water. Also, the trade-off in the filter spacing remains unexplored, despite its simple formulation: A filter too coarse will allow suitably sized prey to pass unintercepted, whereas a filter too fine will cause strong flow resistance. We quantify the feeding flow of the filter......-feeding choanoflagellate Diaphanoeca grandis using particle tracking, and demonstrate that the current understanding of microbial filter feeding is inconsistent with computational fluid dynamics (CFD) and analytical estimates. Both approaches underestimate observed filtration rates by more than an order of magnitude...

    This task examines the potential of the treated waste feed blends to form sodium-aluminum silicate precipitates when evaporated using the zeolite database. To investigate the behavior of the blended pretreated waste feed, an OLI Environmental Simulation Package Software (OLI ESP) model of the treated low activity waste (LAW) evaporator was built. A range of waste feed compositions representative of Envelope A, B, and C were then fed into the OLI model to predict various physical and chemical properties of the evaporator concentrates. Additional runs with treated LAW evaporator were performed to compare chemical and physical property model predictions and experimental results for small-scale radioactive tests of the treated feed evaporation process

    A device for increasing the uniformity of solids within a solids fabrication system, such as a direct light fabrication (DLF) system in which gas entrained powders are passed through the focal point of a moving high-power light which fuses the particles in the powder to a surface being built up in layers. The invention provides a feed through interface wherein gas entrained powders input from stationary input lines are coupled to a rotating head of the fabrication system. The invention eliminates the need to provide additional slack in the feed lines to accommodate head rotation, and therefore reduces feed line bending movements which induce non-uniform feeding of gas entrained powder to a rotating head.

Analysis of the data revealed that 1) only 49% of the children were breast-fed as infants; 2) 50% of the mothers who did breast-feed discontinued breast-feeding before the children were 3 months old; and 3) the weaning diet of at least 1/3 of the children was inadequate. 18% of the children were Malays, 49% were Chinese, and 33% were Indian. The proportion of breast-fed children was highest among the Malays and lowest among the Chinese. Mothers with higher incomes tended to stop breast-feeding earlier than mothers with lower incomes. 67% of the women said they stopped breast-feeding due to inadequate lactation. Most of the children received supplementary foods at relatively early ages. 50% of the infants received starchy foods by the time they were 3 1/2 months old, and 50% received fruit or fruit juice by the time they were 3 1/2 months old. Vegetable products, meat, fish, and eggs were not added to the diet until the children were considerably older. Recommendations, based on the study findings, were 1) hospitals should discontinue the practice of deferring breast-feeding initiation for 24 hours after delivery; 2) mothers should be encouraged to breast-feed fully; and 3) health personnel should discourage the widespread use of costly precooked cereals for supplementary feeding. Tables depicted 1) the frequency distribution of the 100 children by income and by milk feeding patterns according to ethnic affiliation and 2) the cost of serving precooked cereals as compared to the cost of serving home cooked meals.

  1. Social theory and infant feeding

    Science.gov (United States)

    2011-01-01

    Clinicians, public health advisors, nutritionists and others have been attempting to increase breastfeeding rates for the last few decades, with varying degrees of success. We need social science researchers to help us understand the role of infant feeding in the family. Some researchers in the area of food and nutrition have found Pierre Bourdieu's theoretical framework helpful. In this editorial, I introduce some of Bourdieu's ideas and suggest researchers interested in infant feeding should consider testing these theories. PMID:21676218

    The concept of acute delirious puff refers to a transient psychotic state characterized by the sudden outbreak of a polymorphic delusional state in its themes and mecha- nisms. Magnan, in the late of nineteenth century, insti- gated the initial description of this concept. Rediscovered by Henri EY, it's current presence in the French psychiatry despite various attempts to dismantle it results from a singularity based on five cardinal points: it affects young adults, its onset is sudden, delusions are polymorphic and not systematic, there is a marked emotional lability and access is rapidly cured. This entity reveals vulnerability and must be understood carefully by the general practitioner, the issue being the prevention of progression to chronic psychosis.

  3. Development of a Rapid Salivary Proteomic Platform for Oral Feeding Readiness in the Preterm Newborn

    Full Text Available Oral feeding competency is a major determinant of length of stay in the neonatal intensive care unit. An infant must be able to consistently demonstrate the ability to take all required enteral nutrition by mouth before discharge home. Most infants born prematurely (<37 weeks will require days, if not weeks, to master this oral feeding competency skill. Inappropriately timed feeding attempts can lead to acute and long-term morbidities, prolonged hospitalizations, and increased health-care costs. Previously, a panel of five genes involved in essential developmental pathways including sensory integration (nephronophthisis 4, Plexin A1, hunger signaling [neuropeptide Y2 receptor (NPY2R, adenosine-monophosphate-activated protein kinase (AMPK], and facial development (wingless-type MMTV integration site family, member 3 required for oral feeding success were identified in neonatal saliva. This study aimed to translate these five transcriptomic biomarkers into a rapid proteomic platform to provide objective, real-time assessment of oral feeding skills, to better inform care, and to improve neonatal outcomes. Total protein was extracted from saliva of 10 feeding-successful and 10 feeding-unsuccessful infants matched for age, sex, and post-conceptional age. Development of immunoassays was attempted for five oral feeding biomarkers and two reference biomarkers (GAPDH and YWHAZ to normalize for starting protein concentrations. Normalized protein concentrations were correlated to both feeding status at time of sample collection and previously described gene expression profiles. Only the reference proteins and those involved in hunger signaling were detected in neonatal saliva at measurable levels. Expression patterns for NPY2R and AMPK correlated with the gene expression patterns previously seen between successful and unsuccessful feeders and predicted feeding outcome. Salivary proteins associated with hunger signaling are readily quantifiable in

    Similar to primary progressive aphasia, primary progressive apraxia has been considered to cause slowly progressive apraxia without dementia and to be a dependent disease. Of the 3 cases reported by De Renzi in 1986, 1 case showed slowly progressive apraxia without dementia. Since then, cases of primary progressive apraxia have been reported occasionally. Studies on primary progressive apraxia indicate that not only focal lesions caused by vascular disease or brain trauma but also lesions caused by neurodegenerative disease can cause apraxia alone, thereby supporting the hypothesis that apraxia-associated neurodegeneration may develop in cases of primary progressive apraxia. The pathogenesis of primary progressive apraxia is yet to be elucidated. Clinical features of primary progressive apraxia are not precisely distinguishable from those of corticobasal degeneration (CBD); further, previous studies have indicated that the brain pathology observed in primary progressive apraxia is consistent with that in Alzheimer disease (AD) or Pick disease. "Primary" progressive apraxia may be intrinsically different from slowly progressive apraxia that is associated with CBD, AD, or Pick disease and may show specific pathological findings. On the other hand, primary progressive apraxia may not be a dependent disease but a syndrome characterized by prolonged neurodegeneration that is observed in various degenetive dementias such as CBD, AD, or Pick disease.

  5. Acute decompensated pulmonary hypertension

    2017-11-01

    Full Text Available Acute right heart failure in chronic precapillary pulmonary hypertension is characterised by a rapidly progressive syndrome with systemic congestion resulting from impaired right ventricular filling and/or reduced right ventricular flow output. This clinical picture results from an imbalance between the afterload imposed on the right ventricle and its adaptation capacity. Acute decompensated pulmonary hypertension is associated with a very poor prognosis in the short term. Despite its major impact on survival, its optimal management remains very challenging for specialised centres, without specific recommendations. Identification of trigger factors, optimisation of fluid volume and pharmacological support to improve right ventricular function and perfusion pressure are the main therapeutic areas to consider in order to improve clinical condition. At the same time, specific management of pulmonary hypertension according to the aetiology is mandatory to reduce right ventricular afterload. Over the past decade, the development of extracorporeal life support in refractory right heart failure combined with urgent transplantation has probably contributed to a significant improvement in survival for selected patients. However, there remains a considerable need for further research in this field.

    Full Text Available Background. Prelacteal feed (feeding any other substance before first breastfeeding appears to be common despite its harmful effects. By definition a child provided with prelacteal feed (PLF is not exclusively breastfed and PLF has many implications for the success and early initiation of breastfeeding. Objectives. To describe the prevalence of, nature of, and reasons for and factors associated with PLF. Methods. 647 mother-infant dyads were studied. Data was collected about the sociodemographic features of the family and baby, maternity care, the type of first feed before suckling, and causes of PLF. Maternal weight and height were measured and body mass index was calculated. Results. About 58% of newborns received prelacteal feeds. The commonest PLF was sugar/glucose water (39.6%. The most frequent reasons for giving PLF are tradition (61.0% and mother’s/mother in law’s advice (58.3%. The logistic regression revealed that the independent predictors of PLF are urban residence; maternal education; father’s education; low, middle, and high social class; maternal obesity; receiving antenatal care at private clinics and no antenatal care; Caesarean section; female babies; low birth weight; and admission to neonatal intensive care. Conclusion. Indiscriminate use of PLF should be discouraged in medical education and in antenatal maternal health education.

  9. The Progressive BSSG Rat Model of Parkinson's: Recapitulating Multiple Key Features of the Human Disease.

    Directory of Open Access Journals (Sweden)

    Jackalina M Van Kampen

    Full Text Available The development of effective neuroprotective therapies for Parkinson's disease (PD has been severely hindered by the notable lack of an appropriate animal model for preclinical screening. Indeed, most models currently available are either acute in nature or fail to recapitulate all characteristic features of the disease. Here, we present a novel progressive model of PD, with behavioural and cellular features that closely approximate those observed in patients. Chronic exposure to dietary phytosterol glucosides has been found to be neurotoxic. When fed to rats, β-sitosterol β-d-glucoside (BSSG triggers the progressive development of parkinsonism, with clinical signs and histopathology beginning to appear following cessation of exposure to the neurotoxic insult and continuing to develop over several months. Here, we characterize the progressive nature of this model, its non-motor features, the anatomical spread of synucleinopathy, and response to levodopa administration. In Sprague Dawley rats, chronic BSSG feeding for 4 months triggered the progressive development of a parkinsonian phenotype and pathological events that evolved slowly over time, with neuronal loss beginning only after toxin exposure was terminated. At approximately 3 months following initiation of BSSG exposure, animals displayed the early emergence of an olfactory deficit, in the absence of significant dopaminergic nigral cell loss or locomotor deficits. Locomotor deficits developed gradually over time, initially appearing as locomotor asymmetry and developing into akinesia/bradykinesia, which was reversed by levodopa treatment. Late-stage cognitive impairment was observed in the form of spatial working memory deficits, as assessed by the radial arm maze. In addition to the progressive loss of TH+ cells in the substantia nigra, the appearance of proteinase K-resistant intracellular α-synuclein aggregates was also observed to develop progressively, appearing first in the

    2014-11-09

    Diabetic cerebrovascular diseases are defined as cerebral vascular diseases induced by diabetes with sugar, fat and a series of nutrient substance metabolic disorders, resulting in intracranial large and small vessel diseases. About 20%-40% patients with type 2 diabetes suffer from cerebral blood vessel diseases. Diabetic cerebrovascular diseases are the main causes of death in patients with diabetes mellitus. The major clinical manifestations are asymptomatic cerebral atherosclerosis, stroke, cerebral small vessel disease and acute cerebral vascular disease. The pathogenesis, clinical characteristics, treatment and prognosis of diabetic cerebrovascular disease are obviously different from non-diabetic cerebral vascular diseases. This paper will focus on the diabetic cerebrovascular disease, including its latest research progress. Diabetic cerebral large vascular disease and diabetic cerebral small vessel disease will be reviewed here.

    Addario, Luigi; Di Costanzo, Giovan Giuseppe; Tritto, Giovanni; Cavaglià, Enrico; Angrisani, Basilio; Ascione, Antonio

    2008-07-01

    Hepatocellular carcinoma (HCC) is an accepted indication for liver transplantation (LT). Pre-LT adjuvant ablation treatments to prevent tumour progression and drop out from the waiting list have been increasingly adopted at most transplant centers. Trans-catheter arterial chemo-embolization (TACE) is frequently used, but the procedure can be difficult and severe complications may arise. Among them, acute ischemic pancreatitis occasionally occurs and may clinically mimic a post-embolization syndrome. Fatal outcomes of this complication have been reported exceptionally but never in patients awaiting LT. The present case raises concern about the widespread application of TACE and highlights the need for a critical evaluation of the risks and benefits to patients with monofocal small HCC who are scheduled for LT. Superselective embolization of the tumour-feeding artery and systematic monitoring of serum pancreatic enzymes after this radiological procedure are recommended.

    Full Text Available Abstract Acute graft-versus-host disease (GVHD occurs after allogeneic hematopoietic stem cell transplant and is a reaction of donor immune cells against host tissues. Activated donor T cells damage host epithelial cells after an inflammatory cascade that begins with the preparative regimen. About 35%–50% of hematopoietic stem cell transplant (HSCT recipients will develop acute GVHD. The exact risk is dependent on the stem cell source, age of the patient, conditioning, and GVHD prophylaxis used. Given the number of transplants performed, we can expect about 5500 patients/year to develop acute GVHD. Patients can have involvement of three organs: skin (rash/dermatitis, liver (hepatitis/jaundice, and gastrointestinal tract (abdominal pain/diarrhea. One or more organs may be involved. GVHD is a clinical diagnosis that may be supported with appropriate biopsies. The reason to pursue a tissue biopsy is to help differentiate from other diagnoses which may mimic GVHD, such as viral infection (hepatitis, colitis or drug reaction (causing skin rash. Acute GVHD is staged and graded (grade 0-IV by the number and extent of organ involvement. Patients with grade III/IV acute GVHD tend to have a poor outcome. Generally the patient is treated by optimizing their immunosuppression and adding methylprednisolone. About 50% of patients will have a solid response to methylprednisolone. If patients progress after 3 days or are not improved after 7 days, they will get salvage (second-line immunosuppressive therapy for which there is currently no standard-of-care. Well-organized clinical trials are imperative to better define second-line therapies for this disease. Additional management issues are attention to wound infections in skin GVHD and fluid/nutrition management in gastrointestinal GVHD. About 50% of patients with acute GVHD will eventually have manifestations of chronic GVHD.

    Acute respiratory distress syndrome (ARDS) is a severe respiratory condition that is characterized by rapidly progressive hypoxemia with noncardiogenic pulmonary edema. Despite the improvement of therapeutic methods, the mortality of ARDS is in the range of 40%-50% all over the world. Some studies have shown that a significant number of patients with ARDS had acute cor pulmonale (ACP), and ACP is independently associated with the mortality of patients with ARDS, which has attracted wide attention in recent years. This paper reviewed recent related studies, summarized the prevalence, pathogenesis and diagnostic approaches of ACP in ARDS, especially echocardiography which was considered as a cornerstone for ACP diagnosis, and elucidated the beneficial effects of right ventricular protective ventilatory strategy and prone-positioning on the pulmonary vasculature and right heart, in order to provide a novel idea for the therapy of ACP in ARDS.

    Suboptimal complementary feeding practices contribute to a rapid increase in the prevalence of stunting in young children from age 6 months. The design of effective programmes to improve infant and young child feeding requires a sound understanding of the local situation and a systematic process for prioritizing interventions, integrating them into existing delivery platforms and monitoring their implementation and impact. The identification of adequate food-based feeding recommendations that respect locally available foods and address gaps in nutrient availability is particularly challenging. We describe two tools that are now available to strengthen infant and young child-feeding programming at national and subnational levels. ProPAN is a set of research tools that guide users through a step-by-step process for identifying problems related to young child nutrition; defining the context in which these problems occur; formulating, testing, and selecting behaviour-change recommendations and nutritional recipes; developing the interventions to promote them; and designing a monitoring and evaluation system to measure progress towards intervention goals. Optifood is a computer-based platform based on linear programming analysis to develop nutrient-adequate feeding recommendations at lowest cost, based on locally available foods with the addition of fortified products or supplements when needed, or best recommendations when the latter are not available. The tools complement each other and a case study from Peru illustrates how they have been used. The readiness of both instruments will enable partners to invest in capacity development for their use in countries and strengthen programmes to address infant and young child feeding and prevent malnutrition. © 2013 John Wiley & Sons Ltd.

  17. Acute Pancreatitis in acute viral hepatitis

    2011-03-01

    Full Text Available Introduction: The association of acute viral hepatitis and acute pancreatitis is well described. This study was conducted to find out the frequency of pancreatic involvement in acute viral hepatitis in the Nepalese population. Methods: Consecutive patients of acute viral hepatitis presenting with severe abdominal pain between January 2005 and April 2010 were studied. Patients with history of significant alcohol consumption and gall stones were excluded. Acute viral hepatitis was diagnosed by clinical examination, liver function test, ultrasound examination and confirmed by viral serology. Pancreatitis was diagnosed by clinical presentation, biochemistry, ultrasound examination and CT scan. Results: Severe abdominal pain was present in 38 of 382 serologically-confirmed acute viral hepatitis patients. Twenty five patients were diagnosed to have acute pancreatitis. The pancreatitis was mild in 14 and severe in 11 patients. The etiology of pancreatitis was hepatitis E virus in 18 and hepatitis A virus in 7 patients. Two patients died of complications secondary to shock. The remaining patients recovered from both pancreatitis and hepatitis on conservative treatment. Conclusions: Acute pancreatitis occurred in 6.5 % of patients with acute viral hepatitis. Cholelithiasis and gastric ulcers are the other causes of severe abdominal pain. The majority of the patients recover with conservative management. Keywords: acute viral hepatitis, acute pancreatitis, pain abdomen, hepatitis E, hepatitis A, endemic zone

    We report the case of a young man with sudden onset of diplopia after an upper respiratory tract infection. Based on the first radiological findings acute hemorrhagic leukoencephalitis, a variant of acute disseminated encephalomyelitis, was suspected and treatment with high dose intravenous dexamethasone was started but it was stopped for intolerance. The patient clinically worsened, developing gait instability, ataxia and ophthalmoplegia; brain MRI performed 20 days later showed severe progression of the disease with subependymal dissemination. After brain biopsy of the right temporal lesion the histological diagnosis was glioblastoma. These findings suggest that MRI features of acute hemorrhagic leukoencephalitis may dissimulate the diagnosis of diffuse glioma/glioblastoma. This case underscores the importance of considering diffuse glioma in the differential diagnosis of atypical signs and symptoms of acute hemorrhagic leukoencephalitis and underlines the relevant role of integrating neuroradiologic findings with neuropathology.

    Full Text Available Legume cultivation has sharply decreased in Italy during the last 50 years. Lucerne remains widely grown (with about 12% of its area devoted to dehydration, whereas soybean is definitely the most-grown grain legume. Poor legume cropping is mainly due to the gap in yielding ability with major cereals, which has widened up in time according to statistical data. Lucerne displays definitely higher crude protein yield and somewhat lower economic gap with benchmark cereals than feed grain legumes. Pea because of high feed energy production per unit area and rate of genetic progress, and white lupin because of high protein yield per unit area, are particularly interesting for Italian rain-fed environments. Greater legume cultivation in Europe is urged by the need for reducing energy and green-house gas emissions and excessive and unbalanced global N flows through greater symbiotic N fixation and more integrated crop-animal production, as well as to cope with ongoing and perspective raising prices of feed proteins and N fertilisers and insecurity of feed protein supplies. The transition towards greater legume cultivation requires focused research effort, comprehensive stakeholder cooperation and fair economic compensation for legume environmental services, with a key role for genetic improvement dragged by public breeding or pre-breeding. New opportunities for yield improvement arise from the ongoing development of cost-efficient genome-enabled selection procedures, enhanced adaptation to specific cropping conditions via ecophysiological and evolutionary-based approaches, and more thorough exploitation of global genetic resources.

    The feeding behavior of growing-finishing pigs reared under precision feeding strategies was studied in 35 barrows and 35 females (average initial BW of 30.4 ± 2.2 kg) over 84 d. Five different feeding programs were evaluated, namely a conventional 3-phase program in which pigs were fed with a constant blend of diet A (high nutrient density) and diet B (low nutrient density) and 4 daily phase-feeding programs in which pigs were fed daily with a blend meeting 110, 100, 90, or 80% of the individual Lys requirements. Electronic feeder systems automatically recorded the visits to the feeder, the time of the meals, and the amount of feed consumed per meal. The trial lasted 84 d and the database contained 59,701 feeder visits. The recorded database was used to calculate the number of meals per day, feeding time per meal (min), intervals between meals (min), feed intake per meal (g), and feed consumption rate (feed intake divided by feeding time per meal, expressed in g/min) of each animal. The feeding pattern was predominantly diurnal (73% of the feeder visits). Number of meals, duration of meals, time between meals, feed consumed per meal, and feed consumption rate were not affected by the feeding programs. The females ingested 19% less feed per meal and had a 6% lower feed consumption rate in comparison with the barrows ( feeding behavior was not correlated with diet composition. However, feed efficiency was negatively correlated with amount of feed consumed per meal ( = -0.38, feed consumption rate ( = -0.44, Feed consumption rate was also negatively correlated with protein efficiency ( = -0.44, feed consumption rate and number of meals per day are the variables related most closely to pig production performance results. Current results indicate that using precision feeding as an approach to reduce Lys intake does not interfere with the feeding behavior of growing-finishing pigs.

  7. Child feeding and human rights

    2006-12-01

    Full Text Available Abstract Background The human right to adequate food needs to be interpreted for the special case of young children because they are vulnerable, others make the choices for them, and their diets are not diverse. There are many public policy issues relating to child feeding. Discussion The core of the debate lies in differences in views on the merits of infant formula. In contexts in which there is strong evidence and a clear consensus that the use of formula would be seriously dangerous, it might be sensible to adopt rules limiting its use. However, until there is broad consensus on this point, the best universal rule would be to rely on informed choice by mothers, with their having a clearly recognized right to objective and consistent information on the risks of using different feeding methods in their particular local circumstances. Summary The obligation of the state to assure that mothers are well informed should be viewed as part of its broader obligation to establish social conditions that facilitate sound child feeding practices. This means that mothers should not be compelled to feed in particular ways by the state, but rather the state should assure that mothers are supported and enabled to make good feeding choices. Thus, children should be viewed as having the right to be breastfed, not in the sense that the mother is obligated to breastfeed the child, but in the sense that no one may interfere with the mother's right to breastfeed the child. Breastfeeding should be viewed as the right of the mother and child together.

    Full Text Available This article reviews the various aetiologies of small bowel perforations and their management. In addition to the well-known aetiologies such as trauma, inflammation and circulatory disorders, several new causes of small bowel perforation have been described in recent years. The spectrum reaches from iatrogenic perforations during laparoscopic surgery or enteroscopies to drug-induced perforations with new anticancer agents. The management of small bowel perforations requires a concept consisting of the safe revision of the leaking bowel and the treatment of the peritonitis. Depending on the local situation and the condition of the patient, several treatment options are available. The surgical management of the bowel leak can range from a simple primary closure to a delayed restoration of bowel continuity. When the condition of the bowel or patient is frail, the risk of a failure of a closure or anastomosis is too high, and the exteriorization of the bowel defect as a primary measure is a safe option. The treatment of the peritonitis is also dependent on the condition of the patient and the local situation. Early stages of peritonitis can be treated by a simple peritoneal lavage, either performed by laparoscopy or laparotomy. Severe forms of peritonitis with multi-organ failure and an abdominal compartment syndrome need repeated peritoneal revisions. In such cases, the abdomen can only be closed temporarily. Different technical options are available in order to overcome the difficult care of these patients.

    Full Text Available To provide the review of the macrophage activity products as pathophysiological markers of endometriosis by literature survey (PubMed, Cochrane. Immunoreactive cells and several of their synthesis products concentrations are elevated in the serum and peritoneal fluid in patients with endometriosis. The enhanced reactive proteins contributed to local inflammation and aggregation of endometriotic lesions. Immune response and immune surveillance of tissue play an important role in pathogenesis of endometriosis. Activated macrophages in peritoneal environment secrete immunoreactive cytokines which are responsible for inflammatory cascade of reactions. The immunoreactive cytokines should be a target not only as a disease marker but also as a part of therapeutic protocol.

    Full Text Available Major abdominal trauma, both blunt and penetrating, is commonly seen nowadays, being particularly difficult to manage due to the frequent altered mental status of the patients and severity of associated injuries. The review article aims to make an uptodate study of the current strategies for therapeutic approach of abdominal injuries in polytrauma setting. Review of the medical literature is up to 2015, by using the PubMed/Medline, Science Direct, Cochrane Library and Web of Science databases. We have used different combinations of the keywords of “abdominal trauma”, “liver”, “spleen”, “renal”, to review the reference list of retrieved articles for further relevant studies. Nowadays, we are facing a major change in abdominal trauma therapeutic approach, due to the continuous extending indications and very high successful rate of selective nonoperative management, completed or not with minimally invasive techniques like angiography and angiographic embolization. New imaging methods offer a high-quality characterization of solid organ injuries, being a secure support for decision algorithm in polytrauma patients. After a continuous decrease in number of laparotomies for trauma, new techniques should be developed for maintaining and developing the trauma surgeons' skills. According to the current standards, for a low morbidity and mortality, the trauma patients may be approached by a multidisciplinary and experienced trauma team. Even if nonoperative management is continuously expanding, this may be applied only by a trained and skillful trauma surgeon, who is able to perform difficult surgical techniques at any moments.

    To evaluate the status of feeding practices and analyze the association between feeding practice and health status among Tibetan infants, a cross-sectional survey of 386 women with children aged under 24 months was conducted in rural areas surrounding Lhasa, Tibet. All participants were selected using simple random sampling and were interviewed face-to-face by trained interviewers. Mothers were interviewed to collect information on their feeding practices. A feeding practices index was created using the rank sum ratio method. Most of the infants had been or were being breastfed at the time of the interview. The feeding practices index was significantly and inversely associated with the prevalence of acute upper respiratory infection, and the odds ratio for the qualified feeding practices index vs. the non-qualified feeding practices index was 0.43 (95% confidence interval: 0.20-0.94). There were no measurable associations observed between acute upper respiratory infection, diarrhea, and the feeding practices index after controlling for selected factors. The method of rank sum ratio provides a flexible way to evaluate feeding practices and is easy to understand. Furthermore, appropriate infant feeding practices might play a protective role in Tibetan infants' health.

    Progress in ruminant feed research is no more feasible only based on wet chemical analysis, which is merely able to provide information on chemical composition of feeds regardless of their digestive features and nutritive value in ruminants. Studying internal structural make-up of functional groups/feed nutrients is often vital for understanding the digestive behaviors and nutritive values of feeds in ruminant because the intrinsic structure of feed nutrients is more related to its overall absorption. In this article, the detail information on the recent developments in molecular spectroscopic techniques to reveal microstructural information of feed nutrients and the use of nutrition models in regards to ruminant feed research was reviewed. The emphasis of this review was on (1) the technological progress in the use of molecular spectroscopic techniques in ruminant feed research; (2) revealing spectral analysis of functional groups of biomolecules/feed nutrients; (3) the use of advanced nutrition models for better prediction of nutrient availability in ruminant systems; and (4) the application of these molecular techniques and combination of nutrient models in cereals, co-products and pulse crop research. The information described in this article will promote better insight in the progress of research on molecular structural make-up of feed nutrients in ruminants.

  15. Acute alcohol-induced liver injury

    Full Text Available Alcohol consumption is customary in most cultures and alcohol abuse is common worldwide. For example, more than 50% of Americans consume alcohol, with an estimated 23.1% of Americans participating in heavy and/or binge drinking at least once a month. A safe and effective therapy for alcoholic liver disease (ALD in humans is still elusive, despite significant advances in our understanding of how the disease is initiated and progresses. It is now clear that acute alcohol binges not only can be acutely toxic to the liver, but also can contribute to the chronicity of ALD. Potential mechanisms by which acute alcohol causes damage include steatosis, dysregulated immunity and inflammation and altered gut permeability. Recent interest in modeling acute alcohol exposure has yielded new insights into potential mechanisms of acute injury, that also may well be relevant for chronic ALD. Recent work by this group on the role of PAI-1 and fibrin metabolism in mediating acute alcohol-induced liver damage serve as an example of possible new targets that may be useful for alcohol abuse, be it acute or chronic.

    Acute otitis externa, also known as ‘swimmer’s ear’, is a common disease of children, adolescents and adults. While chronic suppurative otitis media or acute otitis media with tympanostomy tubes or a perforation can cause acute otitis externa, both the infecting organisms and management protocol are different. This practice point focuses solely on managing acute otitis externa, without acute otitis media, tympanostomy tubes or a perforation being present.

    Full Text Available Porcine Epidemic Diarrhea Virus (PEDV, Porcine Delta Corona Virus (PDCoV, and Transmissible Gastroenteritis Virus (TGEV are major threats to swine health and contaminated feed plays a role in virus transmission. The objective of our study was to characterize inactivation of PEDV, PDCoV, and TGEV in various feed ingredient matrices. Samples of complete feed, spray dried porcine plasma, meat meal, meat and bone meal, blood meal, corn, soybean meal, and corn dried distillers grains with solubles were weighed (5 g/sample into scintillation vials and inoculated with 1 mL of PEDV, PDCoV, or TGEV. Samples were incubated at room temperature for up to 56 days. Aliquots were removed at various time points followed by preparing serial 10-fold dilutions and inoculating in cell cultures to determine the amount of surviving virus. Inactivation kinetics were determined using the Weibull model, which estimates a delta value indicating the time necessary to reduce virus concentration by 1 log. Delta values of various ingredients were compared and analyzed as to their nutrient composition. Soybean meal had the greatest delta value (7.50 days for PEDV (P < 0.06 as compared with all other ingredients. High delta values (P < 0.001 were observed in soybean meal for PDCoV (42.04 days and TGEV (42.00 days. There was a moderate correlation between moisture content and the delta value for PDCoV (r = 0.49, P = 0.01 and TGEV (r = 0.41, P = 0.02. There was also a moderate negative correlation between TGEV survival and ether extract content (r = -0.51, P = 0.01. In conclusion, these results indicate that the first log reduction of PDCoV and TGEV takes the greatest amount of time in soybean meal. In addition to this, moisture and ether content appear to be an important determinant of virus survival in feed ingredients.

    We describe the case of a 45-year-old Japanese man who developed acute pericarditis following an acute pulmonary thromboembolism. He had developed shortness of breath 7 days prior to hospitalization and was admitted with severe dyspnea. Echocardiography and laboratory results were compatible with acute pulmonary thromboembolism, which was confirmed by contrast-enhanced chest computed tomography. On the third hospital day, he experienced chest pain exacerbated by inspiration. On the fourth hospital day, his body temperature increased to 39°C and echocardiography revealed circumferential pericardial effusion. A diagnosis of acute pericarditis was made and the patient was treated with colchicine and aspirin. On the fifth hospital day, his symptoms largely subsided. Auscultation revealed pericardial friction rub. Electrocardiography demonstrated diffuse ST-segment elevations. Twenty-four days later, computed tomography revealed the disappearance of both the pericardial effusion and pulmonary arterial emboli. This case was thought to be one of acute pericarditis following acute pulmonary thromboembolism.

    As previous studies mainly focus on understanding the mechanisms of radioresistance in Deinococcus bacteria, the present study aimed at characterizing and verifying the safety use of the GKB-Aid 1995 strain, a member of the radiation-resistant bacterial genus Deinococcus, as an ingredient in feed supplements. Using Vitek 2 system and 16S rRNA gene sequencing, GKB-Aid 1995 most resembles Deinococcus grandis. The Ames test, in vitro chromosomal test, in vivo micronucleus test and acute toxicity test were performed subsequently for its safety evaluation. As there is a possibility that the pigment of GKB-Aid 1995 can pass from feed to eggs intended for human consumption, an acute toxicity test was also carried out in pigmented egg yolk. The results confirmed that GKB-Aid 1995 was non-genotoxic in three genotoxicity experiments, and the LD50 of GKB-Aid 1995 and the pigmented egg yolk in ICR mice was greater than 10 and 12 g kg(-1) body weight, respectively. Overall, these data indicate that GKB-Aid 1995 is a non-toxic substance with no genotoxicity and is therefore safe to be used as a feed supplement or feed additive. This study suggests there is potential in developing GKB-Aid 1995 as an animal feed additive intended to enhance yolk coloration to meet the demand of consumers. Copyright © 2016 Elsevier Inc.

    The United Nations Convention on the Rights of the Child holds governments responsible to ensure children's right to the highest attainable standard of health by providing breastfeeding support, and access to nutritious foods, appropriate health care, and clean drinking water. International experts have identified key child care practices and programmatic activities that are proven to be effective at reducing infant and young child undernutrition, morbidity, and mortality. Nevertheless, progress towards reducing the prevalence of undernutrition has been sporadic across countries of the Sahel sub-region of Sub-Saharan Africa. In view of this uneven progress, a working group of international agencies was convened to 'Reposition children's right to adequate nutrition in the Sahel.' The first step towards this goal was to organize a situational analysis of the legislative, research, and programmatic activities related to infant and young child nutrition (IYCN) in six countries of the sub-region: Burkina Faso, Chad, Mali, Mauritania, Niger, and Senegal. The purposes of this introductory paper are to review current information concerning the nutritional and health status of infants and young children in the Sahel and to summarize international guidelines on optimal IYCN practices. These guidelines were used in completing the above-mentioned situational analyses and encompass specific recommendations on: (i) breastfeeding (introduction within the first hour after birth, exclusivity to 6 months, continuation to at least 24 months); (ii) complementary feeding (introduction at 6 months, use of nutrient dense foods, adequate frequency and consistency, and responsive feeding); (iii) prevention and/or treatment of micronutrient deficiencies (vitamin A, zinc, iron and anaemia, and iodine); (iv) prevention and/or treatment of acute malnutrition; (v) feeding practices adapted to the maternal situation to reduce mother-to-child transmission of HIV; (vi) activities to ensure food

    Elderly people have an increased risk of malnutrition due to biological and physiological changes and underlying disease. Almost 90% of the stroke patients are older than 65 years, and the consequences of acute stroke may lead to additional nutritional problems. This paper reviews nutritional therapy for stroke patients. PubMed was searched (non-systematically) for prospective cohort studies of occurrence, diagnostics and consequences of undernutrition in stroke patients. Randomized trials were examined to identify clinical effects of oral protein and energy supplements or tube feeding on nutritional status and intake, functional status, infections, length of stay, quality of life and mortality. 8-35% of stroke patients are undernourished. Body weight is one of the most important parameters for assessment of nutritional status. Dysphagia occurs in up to 80% of patients with acute stroke and increases the risk of undernutrition, which again leads to prolonged length of stay, reduced functional status and poorer survival. Early nasogastric tube feeding does not increase the risk of pneumonia and may improve survival after six months. Oral supplements lead to a significantly improved nutritional intake in undernourished stroke patients, as well as improved nutritional status and survival in undernourished elderly.

    A number of middle ear diseases are associated with pathologic bone modeling, either formative or resorptive. As such, the pathogenesis of a sclerotic mastoid has been controversial for decades. Experimental studies on acute middle ear infection have shown progressive osteoneogenesis in the bone ...... structures surrounding the middle ear cavity, and a few studies have reported acute changes of the ossicular chain. However, detailed qualitative and quantitative information on ossicular bone modeling dynamics has not been accounted for and is thus the purpose of this study....

    To evaluate clinical characteristics and outcomes of cats undergoing surgical intervention in the course of treatment for severe acute pancreatitis. Retrospective observational study from 2003 to 2007 with a median follow-up period of 2.2 years (range 11 d-5.4 y) postoperatively. Private referral veterinary center. Eight cats. None. Quantitative data included preoperative physical and clinicopathologic values. Qualitative parameters included preoperative ultrasonographic interpretation, perioperative and intraoperative feeding tube placement, presence of free abdominal fluid, intraoperative closed suction abdominal drain placement, postoperative complications, microbiological culture, and histopathology. Common presenting clinical signs included lethargy, anorexia, and vomiting. Leukocytosis and hyponatremia were present in 5 of 8 cats. Hypokalemia, increased total bilirubin, and hyperglycemia were present in 6 of 8 cats. Elevated alanine aminotransferase and aspartate transferase were present in all cats. Surgery for extrahepatic biliary obstruction was performed in 6 cats, pancreatic abscess in 3 cats, and pancreatic necrosis in 1 cat. Six of the 8 cats survived. Five of the 6 cats that underwent surgery for extrahepatic biliary obstruction and 1 cat that underwent pancreatic necrosectomy survived. All 5 of the cats with extrahepatic biliary obstruction secondary to pancreatitis survived. The 2 nonsurvivors included a cat with a pancreatic abscess and a cat with severe pancreatitis and extrahepatic biliary obstruction secondary to a mass at the gastroduodenal junction. Postoperative complications included progression of diabetes mellitus, septic peritonitis, local gastrostomy tube stoma inflammation, local gastrostomy tube stoma infection, and mild dermal suture reaction. Cats with severe acute pancreatitis and concomitant extrahepatic biliary obstruction, pancreatic necrosis, or pancreatic abscesses may benefit from surgical intervention. Cats with extrahepatic

    Nabin, A; Thapa, L J; Paudel, R; Rana, P V S

    2012-01-01

    Three cases of acute intermittent porphyria are reported. While in first case severe pain in abdomen with intermittent exacerbation was the only presentation, the second patient presented as accelerated hypertension and acute abdominal crises in whom the clinical course was characterized by development of deep coma due to inappropriate secretion of antidiuretic hormone before she made complete recovery. The third patient, initially manifested as acute encephalitic syndrome. After initial improvement, she developed features of acute intermittent porphyria i.e. acute abdomen, neuropsychiatric symptoms, and rapidly progressing acute motor neuropathy leading to respiratory and bulbar paralysis. In addition, she developed severe and fluctuating dysautonomia leading to cardiac arrest and fatal termination. The importance of early diagnosis, recognition of autonomic disturbances, prompt treatment and counseling for avoidance of precipitating factors is stressed.

  1. Nietzsche, Pragmatism, and Progress

    OpenAIRE

    Harris, Daniel

    2010-01-01

    In this paper I argue that in Richard Rorty’s pragmatism we find a view of political progress at once at home in Nietzsche’s thought and in the Enlightenment tradition. If we think of progress as indexed to some permanent standard, and then agree that it is Nietzsche who dispels the authority of any such standard, then we may perhaps conclude that after Nietzsche, progress is ruled out. I want to show, however, that we find in Nietzsche comfort for a continued vision of human prog...

    2018-04-01

    This paper discusses the advantages of progress testing. A utopia is described where medical schools would work together to develop and administer progress testing. This would lead to a significant reduction of cost, an increase in the quality of measurement and phenomenal feedback to learner and school. Progress testing would also provide more freedom and resources for more creative in-school assessment. It would be an educationally attractive alternative for the creation of cognitive licensing exams. A utopia is always far away in the future, but by formulating a vision for that future we may engage in discussions on how to get there.

    Full Text Available The use of antibiotics as feed additive improves performance in livestock. However, scientific data related to the use of antibiotics in feed merge spreading of bacterial resistance in animal and human bodies, therefore the usage of antibiotics in animal production is restricted. This condition raise the utilization of natural antibiotic as functional feed such as phytogenics (essential oil, flavonoid, saponin, and tannin, enzyme, probiotic, and prebiotic to improve the livestock’s performance, quality, and health. Functional feeds increase profitability in animal husbandry production and its use is feeds are expected to be functional foods that may have positive effects in human nutrition.

    2016-07-01

    Pediatric leukemia is the single most common malignancy affecting children, representing up to 30% of all pediatric cancers. Dramatic improvements in survival for acute lymphoblastic leukemia (ALL) have taken place over the past 4 decades with outcomes approaching 90% in the latest studies. However, progress has been slower for myeloid leukemia and certain subgroups like infant ALL, adolescent/young adult ALL, and relapsed ALL. Recent advances include recognition of molecularly defined subgroups, which has ushered in precision medicine approaches. We discuss the current understanding of the biology of the various childhood leukemias, recent advances in research, and future challenges in this field. Copyright © 2016 Mosby, Inc.

    2017-11-01

    Full Text Available Abstract Background Feeding behavior study is important for animal husbandry and production. However, few studies were conducted on the feeding behavior and their relationship with feeding efficiency in Pekin ducks. In order to investigate the feeding behavior and their relationship with feed efficiency and other economic traits in Pekin ducks, we selected 358 male Pekin ducks and recorded feeding information between 3 to 6 wk of age using automatic electronic feeders, and compared the feeding behavior under different residual feed intake (RFI levels. Results We observed that total feed time, daily feed intake and feed intake per meal had strong positive correlations with feed efficiency traits; moreover, strong correlation between feed intake per meal and body weight was found (R=0.32, 0.36. Daily feeding rate meal and meal duration had weak correlations with feed efficiency (R=0.14~0.15. The phenotypic correlation of between-meal pauses, with feed efficiency was not observed. When daily changes were analyzed, high RFI ducks had the highest feed consumption over all times, and obvious differences in daily visits were found among different RFI level animals during the middle period; these differences were magnified with age, but there was no difference in daily meal number. Moreover, our data indicate that high RFI birds mainly take their meals at the edge of the population enclosure, where they are more susceptible to environmental interference. Conclusions Overall, this study suggests that the general feeding behaviors can be accurately measured using automatic electronic feeders and certain feeding behaviors in Pekin ducks are associated with improved feed efficiency.

    This paper examines physicians’ progress notes, an artifact that, in spite of its obvious importance in the coordination of cooperative work in clinical settings, has not been subjected to systematic study under CSCW auspices. While several studies have addressed the role of the medical record...... in patient care, they have not dealt specifically with the role, structure, and content of the progress notes. As a consequence, CSCW research has not yet taken fully into account the fact that progress notes are coordinative artifacts of a rather special kind, an open-ended chain of prose texts, written...... sequentially by cooperating physicians for their own use as well as for that of their colleagues.

  16. Malnutrition in Patients with Acute Stroke

    Directory of Open Access Journals (Sweden)

    Stella D. Bouziana

    2011-01-01

    Full Text Available Stroke is a devastating event that carries a potential for long-term disability. Malnutrition is frequently observed in patients with stroke, and dysphagia contributes to malnutrition risk. During both the acute phase of stroke and rehabilitation, specific nutritional interventions in the context of a multidisciplinary team effort can enhance the recovery of neurocognitive function. Early identification and management of malnutrition with dietary modifications or specific therapeutic strategies to ensure adequate nutritional intake should receive more attention, since poor nutritional status appears to exacerbate brain damage and to contribute to adverse outcome. The main purpose of nutritional intervention should be the prevention or treatment of complications resulting from energy-protein deficit. This paper reviews the evaluation and management of malnutrition and the use of specialized nutrition support in patients with stroke. Emphasis is given to enteral tube and oral feeding and to strategies to wean from tube feeding.

    Acute appendicitis and acute cholecystitis are among the most common diagnoses that general surgeons operate on. However, it is rarely described in its synchronous form. A 43 year-old woman attending the clinic for right upper quadrant pain of 11 days duration. The patient refers to intermittent radiating pain in the right side, with positive Murphy, tachycardia, and fever. The laboratory results showed white cells 16,200/mm(3), glucose 345 mg/dl, abnormal liver function tests. Acute cholecystitis was reported with ultrasound. A Masson-type incision was made, noting an enlarged pyogenic gallbladder with thickened walls, sub-hepatic abscess of approximately 300 ml, greenish-yellow colour, and foetid. An anterograde subtotal cholecystectomy is performed due to difficulty in identifying elements of Calot triangle due to the inflammatory process, opening it and extracting stones. The right iliac fossa is reviewed, finding a plastron and a sub-serous retrocaecal appendix perforated in its middle third with free fecalith and an abscess in the pelvic cavity. An anterograde appendectomy was performed and the patient progressed satisfactorily, later being discharged due to improvement. In this patient, with a history of recurrent episodes of gallbladder pain and disseminated acute abdominal pain without peritoneal irritation, clinical suspicion was exacerbated cholecystitis with probable empyema of the gallbladder. Open surgery approach for this patient allowed access to both the appendix and gallbladder in order to perform a complete exploration of the abdominal cavity. The synchronous presentation of cholecystolithiasis and complicated appendicitis has not been reported in the literature. Copyright © 2015 Academia Mexicana de Cirugía A.C.

    Continuous quality improvement is a tool and a methodology that allows nephrology nurses to monitor, evaluate, and creatively improve their working environment. Using an established, consistent, and easily understood format enables information sharing and facilitates progress toward establishing best practice guidelines and standards. Strengthening the nursing knowledge base improves the care provided to patients, which improves outcomes. Use of CQI methods can facilitate better processes, which in turn influence acute care practice. The cycle and the process never end since new knowledge is critical to provide the best care to patients. The Acute Care SIG will continue the PDCA cycle to Act in response to the changing needs of patients in the acute care setting and to our membership in the acute care arena.

    Full Text Available ABSTRACT Objective: To draw attention to the importance of interaction between caregiver and child during feeding and the influence of parenting style on dietary habit formation. Source of data: A search was performed in the PubMed and Scopus databases for articles addressing responsive feeding; the articles considered most relevant by the authors were selected. Synthesis of data: The way children are fed is decisive for the formation of their eating habits, especially the strategies that parents/caregivers use to stimulate feeding. In this context, responsive feeding has been emphasized, with the key principles: feed the infant directly and assist older children when they already eat on their own; feed them slowly and patiently, and encourage children to eat but do not force them; if the child refuses many types of foods, experiment with different food combinations, tastes, textures, and methods of encouragement; minimize distractions during meals; and make the meals an opportunity for learning and love, talking to the child during feeding and maintaining eye contact. It is the caregiver's responsibility to be sensitive to the child's signs and alleviate tensions during feeding, and make feeding time pleasurable; whereas it is the child's role to clearly express signs of hunger and satiety and be receptive to the caregiver. Conclusion: Responsive feeding is very important in dietary habit formation and should be encouraged by health professionals in their advice to families.

    The potential for necrotizing enterocolitis (NEC) in neonates requiring cardiac surgery has contributed largely to wide feeding practice variations and a hesitation to initiate enteral feeding during the preoperative period, specifically those patients with hypoplastic left heart syndrome. A retrospective chart review of neonates undergoing cardiac surgery at a single institution between July 2011 and July 2013 was performed. The primary objective of this study was to determine if preoperative feeding was associated with NEC in neonates requiring cardiac surgery. Univariable and multivariable analyses were performed to evaluate the relationship between preoperative feeding and NEC. Secondary outcomes including growth failure, total ventilator days, total length of stay, and tube-assisted feeds at discharge were analyzed. One hundred thirty consecutive neonates who required cardiac surgery were included in the analysis. Preoperative feeding occurred in 61% (n = 79). The overall prevalence of NEC was 9% (12/130), including three neonates with surgical NEC. There was no difference in the prevalence of NEC between the preoperative feeding and nil per os (NPO) groups. Preoperative NPO status was associated with longer ventilator-dependent days ( P = .01) but was not associated with worsened growth failure, longer length of stay, or increased prevalence of tube-assisted feeds at discharge. In this study cohort, preoperative feeding was associated with a low prevalence of NEC. Larger prospective studies evaluating the safety and benefits of preoperative feeding in cardiac neonates are warranted.

    The obstructive acute abdomen is a common presentation, for which safe and effective management depends on a fast and accurate diagnosis. Conventional radiograph remains the first choice among the imaging exams because of its availability, low cost and the possibility to be done serially to follow the patient's clinical progression. The ultrasonography does not require ionizing radiation. It is a dynamic and in realtime exam. Computed tomography is used increasingly due to the provision of essential diagnostic information not apparent from radiographs, such as the confirmation of the obstruction, degree and place of the occlusion, presence of ischemia as well as the causes of the obstruction. Magnetic resonance imaging has presented great technological advances and it may play a role in the future of obstructive acute abdomen diagnosis. The objective of this pictorial essay is to review the different imaging techniques used on diagnosing obstructive acute abdomen. (author)

    Postpartum blues occurs in 50-80% of women. A few percent of the cases are classified as serious postpartum depression, requiring antidepressant treatment. There is a growing understanding that women should continue to breast-feed in this situation. Data concerning the transfer of antidepressants into breast milk has been researched. Calculations of the infant relative dose via breast milk were done for the drugs concerned. Few antidepressants have been studied at steady state conditions in nursing mothers. Nortriptyline and amitriptyline have minimal relative doses and can be used when breast-feeding. Doxepine should be avoided, as should lithium, which has a significant transfer. Among the serotonine-reuptake inhibitors fluoxetine has been well studied in breast milk. Since fluoxetine has a long half life and a high transfer, sertraline and possibly paroxetine are better alternatives, but the latter has not yet been studied in repeated doses. Moclobemide also lacks data from multiple dose studies, but extrapolation to steady state indicates that the relative dose is small. More observational studies should be carried out in infants breast-fed by mothers using antidepressants. In the meantime, doctors prescribing antidepressant drugs to nursing mothers should see that the infants are monitored for side effects.

    Acute pancreatitis is an acute inflammation of the pancreas. Several classification systems have been used in the past but were considered unsatisfactory. A revised Atlanta classification of acute pancreatitis was published that assessed the clinical course and severity of disease; divided acute pancreatitis into interstitial edematous pancreatitis and necrotizing pancreatitis; discerned an early phase (first week) from a late phase (after the first week); and focused on systemic inflammatory response syndrome and organ failure. This article focuses on the revised classification of acute pancreatitis, with emphasis on imaging features, particularly on newly-termed fluid collections and implications for the radiologist.

    Acute cor pulmonale is a form of acute right heart failure produced by a sudden increase in resistance to blood flow in the pulmonary circulation, which is now rapidly recognized by bedside echocardiography. In the clinical setting, acute cor pulmonale is mainly observed as a complication of massive pulmonary embolism or acute respiratory distress syndrome. In acute respiratory distress syndrome, the worsening effect of mechanical ventilation has been recently emphasized. As a general rule, the treatment consists in rapidly reducing resistance to blood flow in the pulmonary circulation, obtained by a specific strategy according to etiology.

    Dengue infection can have spectrum of manifestations, often with an unpredictable clinical progression and outcome. There have been increasing reports of atypical manifestations. Abdominal pain or tenderness and persistent vomiting (warning signs) are present in the majority of cases with severe dengue prior to clinical deterioration. We report a 10-year-old child who presented with fever, persistent vomiting, and abdominal pain. A diagnosis of acute pancreatitis was made. This is a very infrequently reported complication of dengue hemorrhagic fever.

    Insulin detemir (DET) is a basal insulin analog that, in contrast to other long-acting forms of insulin, has significant weight-gain-sparing effects in diabetic patients. We hypothesized that this effect of DET may be due to its enhanced catabolic action in the central nervous system. We investigated the long-term effects of single third ventricular (3V) microinjections of equimolar doses of DET and regular insulin in normal male rats on feeding, body weight, energy expenditure (EE), and respiratory quotient (RQ). Also, in acute testing, we assessed the ability of lower doses of DET to alter feeding, EE, and RQ when microinjected directly into the paraventricular nucleus (PVN). The anabolic peptide ghrelin served as a positive control in acute testing. 3V administration of both DET (0.5-2.0 mU) and regular insulin (2.0-8.0 mU) significantly reduced feeding and body weight over 48 and 120 h, respectively, with DET yielding greater inhibitory effects. DET also stimulated greater elevations of EE and reductions of RQ over 72 and 48 h postinjection, respectively. In acute (4 h) testing, microinjections of DET (0.5 mU) into the PVN reduced feeding, increased EE, and reduced RQ, while ghrelin (100 pmol) had the opposite effects. When administered sequentially into the PVN, DET (0.25 and 0.5 mU) reversed ghrelin-induced feeding, EE, and RQ effects. These data support the notion that the weight-sparing effect of DET is at least in part based on its central catabolic action and that enhanced EE and reduced RQ may participate in this effect.

    The total rate of N-waste excretion (M N ) in juvenile tambaqui living in ion-poor Amazonian water comprised 85 % ammonia-N (M Amm-N ) and 15 % urea-N (M Urea-N ). Both occurred mainly across the gills with only ~5 % of M Amm-N and ~39 % of M Urea-N via the urine. Tambaqui were not especially tolerant to high environmental ammonia (HEA), despite their great resistance to other environmental factors. Nevertheless, they were able to maintain a continued elevation of M Amm-N during and after 48-h exposure to 2.5 mmol L -1 HEA. The normally negative transepithelial potential (-18 mV) increased to -9 mV during the HEA period, which would help to reduce branchial NH 4 + entry. During 3 h of acute environmental hypoxia (30 % saturation), M Amm-N declined, and recovered thereafter, similar to the response seen in other hypoxia-tolerant teleosts; M Urea-N did not change. However, during gradual hypoxia, M Amm-N remained constant, but M Urea-N eventually fell. The acute temperature sensitivities of M Amm-N and M N were low from 28 °C (acclimation) to 33 °C (Q10 ~1.5), but high (~3.8) from 33 to 38 °C, relative to [Formula: see text] (~1.9 throughout). In contrast, M Urea-N exhibited a different pattern over these temperature ranges (Q10 2.6 and 2.1, respectively). The nitrogen quotient (NQ = 0.16-0.23) was high at all temperatures, indicating a 60-85 % reliance on protein to fuel aerobic metabolism in these fasting animals. During steady-state aerobic exercise, [Formula: see text] and M Urea-N increased in parallel with velocity (up to 3.45 body lengths s -1 ), but M Amm (and thus M N ) remained approximately constant. Therefore, the NQ fell progressively, indicating a decreasing reliance on protein-based fuels, as work load increased. In group feeding trials using 45 % protein commercial pellets, tambaqui excreted 82 % (range 39-170 %) of the dietary N within 24 h; N-retention efficiency was inversely related to the ration voluntarily consumed.

    A juvenile cheetah (Acinonyx jubatus) died with rapidly progressive pyrexia, tachypnea, abdominal effusion, and hepatomegaly. Postmortem examination revealed lesions consistent with acute disseminated infection with Toxoplasma gondii. The presence of this organism was confirmed in multiple organs by immunohistochemistry and polymerase chain reaction. To the best of our knowledge, we propose this to be the first reported case of primary acute disseminated toxoplasmosis in a cheetah.

    A long-lasting immunological suppression action seems to be produced by total lymphoid irradiation; some authors emphasize the favorable effect of this treatment on chronic progressive multiple sclerosis. In order to evaluate the actual role of TLI, 6 patients affected with chronic progressive multiple sclerosis were submitted to TLI with shaped and personalized fields at the Istituto del Radio, University of Brescia, Italy. The total dose delivered was 19.8 Gy in 4 weeks, 1.8 Gy/day, 5d/w; a week elapsed between the first and the second irradiation course. Disability according to Kurtzke scale was evaluated, together with blood lymphocyte count and irradiation side-effects, over a mean follow-up period of 20.8 months (range: 13-24). Our findings indicate that: a) disease progression was not markedly reduced by TLI; b) steroid hormones responsivity was restored after irradiation, and c) side-effects were mild and tolerable

    Batwing membrane was used to study salivation and feeding behaviour of tsetse flies. Probing and salivation were observed to be stimulated by tarsal contact with the membrane. Salivation and feeding responses varied from day to day with characteristic alternating high and low responses. The feeding process was invariably accompanied by a resting period. Attempts to rear G. morsitans artificially through the use of batwing membrane showed that the flies needed an initial adjustment period to in vitro maintenance. (author)

    The endogenous opioid system supports a multitude of functions related to appetitive behavior in humans and animals, and it has been proposed to govern hedonic aspects of feeding thus contributing to the development of obesity. Here we used positron emission tomography to investigate whether feeding results in hedonia-dependent endogenous opioid release in humans. Ten healthy males were recruited for the study. They were scanned with the μ-opioid-specific ligand [ 11 C]carfentanil three times, as follows: after a palatable meal, a nonpalatable meal, and after an overnight fast. Subjective mood, satiety, and circulating hormone levels were measured. Feeding induced significant endogenous opioid release throughout the brain. This response was more pronounced following a nonpalatable meal versus a palatable meal, and independent of the subjective hedonic responses to feeding. We conclude that feeding consistently triggers cerebral opioid release even in the absence of subjective pleasure associated with feeding, suggesting that metabolic and homeostatic rather than exclusively hedonic responses play a role in the feeding-triggered cerebral opioid release. SIGNIFICANCE STATEMENT The endogenous opioid system supports both hedonic and homeostatic functions. It has been proposed that overeating and concomitant opioid release could downregulate opioid receptors and promote the development of obesity. However, it remains unresolved whether feeding leads to endogenous opioid release in humans. We used in vivo positron emission tomography to test whether feeding triggers cerebral opioid release and whether this response is associated with pleasurable sensations. We scanned volunteers using the μ-opioid receptor-specific radioligand [ 11 C]carfentanil three times, as follows: after an overnight fast, after consuming a palatable meal, and after consuming a nonpalatable meal. Feeding led to significant endogenous opioid release, and this occurred also in the absence of feeding

  9. Behavioral Change Strategies for Improving Complementary Feeding and Breastfeeding.

    2016-01-01

    Improving infant and young child feeding (IYCF) practices, including breastfeeding and complementary feeding, has been identified as one of the most effective interventions to improve child survival, stunting and wasting. Evidence from randomized controlled trials suggests that effective promotion of breastfeeding and complementary feeding, with or without food provision, has the potential to improve IYCF practices and child nutrition. However, in many countries, breastfeeding practices and complementary feeding practices are still far from optimal. The lack of implementation of available, effective, affordable interventions in scale-up programs is in part attributed to a lack of innovative, creative and effective behavioral change strategies that enable and encourage caregivers. Successful behavioral change strategies should be based on a rigorous situational analysis and formative research, and the findings and insights of formative research should be used to further design interventions that address the identified barriers and enablers, to select delivery channels, and to formulate appropriate and effective messages. In addition, successful behavioral change interventions should a priori define and investigate the program impact pathway to target behavioral change and should assess intermediary behavioral changes and indicators to learn why the expected outcome was achieved or not achieved by testing the program theory. The design of behavioral change communication must be flexible and responsive to shifts in societies and contexts. Performance of adequate IYCF also requires investments to generate community demand through social mobilization, relevant media and existing support systems. Applying these principles has been shown to be effective in improving IYCF practices in Vietnam, Bangladesh and Ethiopia and is recommended to be adopted by other programs and countries in order to accelerate progress in improving child nutrition. © 2016 S.

    Efficiency of production is increasingly important with the current escalation of feed costs and demands to minimize the environmental footprint. The objectives of this study were 1) to estimate heritabilities for daily feed consumption and residual feed intake and their genetic correlations with production and egg-quality traits; 2) to evaluate accuracies of estimated breeding values from pedigree- and marker-based prediction models; and 3) to localize genomic regions associated with feed efficiency in a brown egg layer line. Individual feed intake data collected over 2-wk trial periods were available for approximately 6,000 birds from 8 generations. Genetic parameters were estimated with a multitrait animal model; methods BayesB and BayesCπ were used to estimate marker effects and find genomic regions associated with feed efficiency. Using pedigree information, feed efficiency was found to be moderately heritable (h(2) = 0.46 for daily feed consumption and 0.47 for residual feed intake). Hens that consumed more feed and had greater residual feed intake (lower efficiency) had a genetic tendency to lay slightly more eggs with greater yolk weights and albumen heights. Regions on chromosomes 1, 2, 4, 7, 13, and Z were found to be associated with feed intake and efficiency. The accuracy from genomic prediction was higher and more persistent (better maintained across generations) than that from pedigree-based prediction. These results indicate that genomic selection can be used to improve feed efficiency in layers.

    The aim of the present study was to compare orofacial motion and mouth angle during breast-feeding and bottle feeding in normal infants. Thirteen normal infants were enrolled in the study, and feeding sessions were recorded using a digital video camera at 4 or 5 days following birth. The analysis was successfully performed for 12 infants during both breast-feeding and bottle feeding. Markers were placed at the lateral angle of the eye, the tip of the jaw, and the throat region. Jaw and throat region movements were calculated using the direct linear transformation method. The angle of the mouth was also measured. Throat region movement was significantly larger than jaw movement in both breast-feeding (eye-throat region changes: 1.51 +/- 0.37 mm, eye-jaw changes: 0.91 +/- 0.31 mm, P jaw changes: 1.77 +/- 0.33 mm, P Jaw and throat region movements were significantly smaller during breast-feeding than those during bottle feeding (P breast-feeding is larger than that during bottle feeding (P jaw movement. Jaw and throat region movements during bottle feeding differ from those during breast-feeding. This partly results from the difference in the angle of the mouth during feeding.

    Full Text Available Abstract Background Early enteral nutrition is recommended in cases of critical illness. It is unclear whether this recommendation is of most benefit to extremely ill patients. We aim to determine the association between illness severity and commencement of enteral feeding. Methods One hundred and eight critically ill patients were grouped as “less severe” and “more severe” for this cross-sectional, retrospective observational study. The cut off value was based on Acute Physiology and Chronic Health Evaluation II score 20. Patients who received enteral feeding within 48 h of medical intensive care unit (ICU admission were considered early feeding cases otherwise they were assessed as late feeding cases. Feeding complications (gastric retention/vomiting/diarrhea/gastrointestinal bleeding, length of ICU stay, length of hospital stay, ventilator-associated pneumonia, hospital mortality, nutritional intake, serum albumin, serum prealbumin, nitrogen balance (NB, and 24-h urinary urea nitrogen data were collected over 21 days. Results There were no differences in measured outcomes between early and late feedings for less severely ill patients. Among more severely ill patients, however, the early feeding group showed improved serum albumin (p = 0.036 and prealbumin (p = 0.014 but worsened NB (p = 0.01, more feeding complications (p = 0.005, and prolonged ICU stays (p = 0.005 compared to their late feeding counterparts. Conclusions There is a significant association between severity of illness and timing of enteral feeding initiation. In more severe illness, early feeding was associated with improved nutritional outcomes, while late feeding was associated with reduced feeding complications and length of ICU stay. However, the feeding complications of more severely ill early feeders can be handled without significantly affecting nutritional intake and there is no eventual difference in length of hospital stay or mortality

  13. Dietary management of acute diarrhoea in childhood.

    1993-04-17

    Gastroenteritis in children is usually treated with the graded introduction of milk feeds after rehydration. Although having never been rigorously tested, the practice of gradually increasing milk strength over several days has been considered an appropriate means of warding against lactose intolerance and preventing sensitization to cow's milk antigens. These guidelines were formulated in Europe and North America and invariably lead to a reduction in nutrient intake. Malnourished children in developing countries, however, may experience an average 5-6 episodes of acute diarrhea per year and the nutrient effects are cumulative. A recent study from Latin America explored whether continued feeding is safe for infants under age 6 months and whether malnourished children respond adversely. Infants randomly assigned to receive full strength cow's milk immediately after rehydration did not have more treatment failures, higher stool outputs, or longer lasting diarrhea than those whose feeds were regarded to full strength over 48 hours. It is unclear, however, whether the youngest or more malnourished subjects were overrepresented in the treatment failures. Results also indicate that deciding to change treatment should not be dictated by the presence of reducing substances in the faeces; the majority of infants with reducing substances in their stools did well. This study offers the first scientific support for rapidly reintroducing full-strength milk formula after gastroenteritis is malnourished patients under 6 months of age. The 10% of infants in which dehydration recurs after reintroducing milk feeds are still difficult to manage. In the absence of yogurt or lactose-free formula, a locally-produced modular feed of chicken, starch, and vegetable oil may be suitable.

  14. The importance of postural control for feeding.

    Science.gov (United States)

    Redstone, Fran; West, Joyce F

    2004-01-01

    Children with cerebral palsy and other neurodisabilities often have decreased postural control that exacerbates their feeding/swallowing disorders. Correct postural alignment is important in the normal feeding/swallowing process. In the child with cerebral palsy, the alignment and stability of the oral structures for feeding/swallowing may be compromised by abnormal muscle tone and movement patterns. Effective oral functioning for feeding begins with attaining better head stability to improve jaw control. Head control is influenced by trunk alignment, which depends upon the stability of the pelvic area. Techniques such as therapeutic seating and oral control can enhance postural alignment and improve oral functioning for the safe intake of food.

    2012-02-01

    Researchers use the Caregiver's Feeding Styles Questionnaire (CFSQ) to categorize parent feeding into authoritative, authoritarian, indulgent, and uninvolved styles. The CFSQ assesses self-reported feeding and classifies parents using median splits which are used in a substantial body of parenting literature and allow for direct comparison across studies on dimensions of demandingness and responsiveness. No national norms currently exist for the CFSQ. This paper establishes and recommends cutoff points most relevant for low-income, minority US samples that researchers and clinicians can use to assign parents to feeding styles. Median scores for five studies are examined and the average across these studies reported. Copyright © 2011 Elsevier Ltd. All rights reserved.

    What is Goal Attainment Scaling? In this article, Lee Ann Jung defines it as a way to measure a student's progress toward an individualized goal. Instead of measuring a skill at a set time (for instance, on a test or other assignment), Goal Attainment Scaling tracks the steps a student takes over the course of a year in a targeted skill. Together,…

    In this article, the author explores what Assessing Pupils' Progress (APP) is about. He contends that the predilection for testing is a catastrophe as far as the teaching and learning of mathematics is concerned; it is an outcome of the drive for collecting so-called "data" on pupils. What those people, who should know better, either choose to…

    Develop a questionnaire to assess family-based feeding strategies, strengths, and mealtime structure for use with children with feeding problems; validate this new instrument with caregivers of young children from the community and a specialty feeding-clinic; and examine preliminary evidence for reliability and validity. Community caregivers (n = 702) and caregivers seeking services at a pediatric feeding specialty clinic (n = 288) completed the Feeding Strategies Questionnaire (FSQ). A smaller portion of these families also completed an established feeding measure. Exploratory and confirmatory factor analyses were conducted to develop and validate the FSQ factor structure that resulted in six scales: Mealtime Structure, Consistent Mealtime Schedule, Child Control of Intake, Parent Control of Intake, Between Meal Grazing and Encourages Clean Plate. Evidence of reliability and validity was obtained. It appears the FSQ can aid the assessment of feeding strategies relevant to the prevention or treatment of pediatric feeding difficulties.

  19. Acute colonic pseudo-obstruction in vascular patients (Ogilvie syndrome).

    Two patients with acute colonic pseudo-obstruction are presented. Acute colonic pseudo-obstruction, first described by Ogilvie in 1948, is characterised by signs of colonic obstruction, but without mechanical obstruction to the intestinal flow. The current hypothesis states that it is caused by an imbalance between sacral parasympathetic excitatory nerves and sympathetic inhibitory nerves, thus inducing functional obstruction. It mostly develops in hospitalised patients with a variety of medical and surgical conditions. Two such patients with extensive co-morbidities, developed progressive colon dilatation with signs of acute peritonitis, and were operated on urgently. In both patients, right hemicolectomy and postoperative medical treatment resulted in complete recovery.

  20. Progression og underviserkompetencer

    Directory of Open Access Journals (Sweden)

    2014-03-01

    Full Text Available På baggrund af en kvalitativ interviewundersøgelse af undervisere ved Aarhus Universitet lavet i 2012, tematiserer artiklen, hvordan undervisere udvikler deres faglige og pædagogiske kompetencer i forhold til at kunne skabe progression inden for innovation og entreprenørskab forstået enten som didaktik, arbejdsformer i faglige forløb eller som fag på universitetet. I arbejdet med progression er det en udfordring at integrere de nye faglige dimensioner i det kernefaglige felt. Den seneste model for progression inden for innovation og entreprenør-skab siger, at det er den lærendes generelle erfaringsniveau, der er den afgørende progressionsskabende faktor (Progressionsmodellen, Fonden for Entreprenørskab, 2013b. Samtidig skelner international forskning inden for studiekompetenceområdet mellem niveauer, hvor indlejret viden er det mest avancerede kompetenceniveau (Barrie, 2002.Ifølge progressionsmodellen og den nævnte kompetenceforskning er erfaring og dybt integreret læring altså centrale dimensioner i progression. Men hvad er underviserens rolle heri? Underviserens professionelle udviklingsarbejde forekommer at være underbelyst i forhold til, at underviseren er den legitime garant for integrationen af nye faglige dimensioner og for den studerendes kompetenceniveau. Interviewundersøgelsen forholder sig til spørgsmålet om progression gennem de deltagende underviseres beskrivelse af betydningslag i entreprenørskabsbegrebet koblet til de praksisformer i undervisningen, der knytter sig hertil samt et indblik i undervisernes refleksioner over deres kompetenceudviklingsprocesser. Artiklens bidrag til progression er at se underviserens motivation og kompetenceudvikling som forudsætninger herfor.  Based on a qualitative study of five teachers in the Faculty of Arts at Aarhus University that took place during 2012, the article thematizes how teachers develop their professional and educational qualifications in innovation and
