Methods Ten physically active males (20.8 ± 0.6 y; 176.8 ± 7.2 cm; 77.4 ± 10.5 kg; 12.3 ± 4.6% body fat volunteered to participate in this study. During the first visit (T1 subjects reported to the laboratory in a euhydrated state to provide a baseline (BL blood draw and perform a maximal exercise test. In the four subsequent randomly ordered trials, subjects dehydrated to -2.5% of their baseline body mass. For T2, subjects achieved their goal weight and were not rehydrated. During T3 - T5, subjects reached their goal weight and then rehydrated to 1.5% of their baseline body mass by drinking either water (T3 or two different doses (T4 and T5 of the AG supplement (0.05 g·kg-1 and 0.2 g·kg-1, respectively. Subjects then exercised at a workload that elicited 75% of their VO2 max on a cycle ergometer. During T2 - T5 blood draws occurred once goal body mass was achieved (DHY, immediately prior to the exercise stress (RHY, and immediately following the exercise protocol (IP. Resting 24 hour (24P blood samples were also obtained. Blood samples were analyzed for glutamine, potassium, sodium, aldosterone, arginine vasopressin (AVP, C-reactive protein (CRP, interleukin-6 (IL-6, malondialdehyde (MDA, testosterone, cortisol, ACTH, growth hormone and creatine kinase. Statistical evaluation of performance, hormonal and biochemical changes was accomplished using a repeated measures analysis of variance. Results Glutamine concentrations for T5 were significantly higher at RHY and IP than T2 - T4. When examining performance changes (difference between T2 - T5 and T1, significantly greater times to exhaustion occurred during T4 (130.2 ± 340.2 sec and T5 (157.4

    Full Text Available Abstract Background The purpose of this study was to examine the efficacy of L-alanyl-L-glutamine (AG ingestion on basketball performance, including jump power, reaction time, shooting accuracy and fatigue. Methods Ten women (21.2 ± 1.6 years; height: 177.8 ± 8.7 cm; body mass: 73.5 ± 8.0 kg, all scholarship NCAA Division I basketball players, volunteered for this study. Subjects participated in four trials, each consisting of a 40-min basketball game with controlled time-outs for rehydration. During the first trial (DHY subjects were not allowed to rehydrate, and the total weight lost during the contest was used to determine fluid replenishment during the subsequent three trials. During one trial subjects consumed only water (W, while during the other two trials subjects consumed the AG supplement mixed in water using either a low dose (1 g per 500 ml (AG1 or high dose (2 g per 500 ml (AG2 concentration. All data assessed prior to and following each game were converted into a Δ score (Post results - Pre results. All performance data were then analyzed using a one-way repeated measures analysis of variance. Results During DHY subjects lost 1.72 ± 0.42 kg (2.3% of their body mass. No differences in fluid intake (1.55 ± 0.43 L were seen between rehydration trials. A 12.5% (p = 0.016 difference in basketball shooting performance was noted between DHY and AG1 and an 11.1% (p = 0.029 difference was seen between AG1 and W. Visual reaction time was significantly greater following AG1 (p = 0.014 compared to DHY. Differences (p = 0.045 in fatigue, as determined by player loads, were seen only between AG2 and DHY. No differences were seen in peak or mean vertical jump power during any trial. Conclusion Rehydration with AG appears to maintain basketball skill performance and visual reaction time to a greater extent than water only.

    In this work, we aimed to investigate the effects of long-term supplementations with L-glutamine or L-alanyl-L-glutamine in the high-fat diet (HFD)-fed B6.129SF2/J mouse model over insulin sensitivity response and signaling, oxidative stress markers, metabolism and HSP70 expression. Mice were fed in a standard low-fat diet (STA) or a HFD for 20 weeks. In the 21th week, mice from the HFD group were allocated in five groups and supplemented for additional 8 weeks with different amino acids: HFD control group (HFD-Con), HFD + dipeptide L-alanyl-L-glutamine group (HFD-Dip), HFD + L-alanine group (HFD-Ala), HFD + L-glutamine group (HFD-Gln), or the HFD + L-alanine + L-glutamine (in their free forms) group (HFD-Ala + Gln). HFD induced higher body weight, fat pad, fasted glucose, and total cholesterol in comparison with STA group. Amino acid supplementations did not induce any modifications in these parameters. Although insulin tolerance tests indicated insulin resistance in all HFD groups, amino acid supplementations did not improve insulin sensitivity in the present model. There were also no significant differences in the immunocontents of insulin receptor, Akt, and Toll-like receptor-4. Notably, total 70 kDa heat shock protein (HSP72 + HSP73) contents in the liver was markedly increased in HFD-Con group as compared to STA group, which might suggest that insulin resistance is only in the beginning. Apparently, B6.129SF2/J mice are more resistant to the harmful effects of HFD through a mechanism that may include gut adaptation, reducing the absorption of nutrients, including amino acids, which may explain the lack of improvements in our intervention.

Initially, this study verified the effect of L-glutamine and L-alanyl-L-glutamine supplementation on the response to delayed-type hypersensitivity test (DTH in rats submitted to intense swimming training for six weeks. Later on, we assessed the effect of these nutritional interventions on total and differential white blood cell counts and on concentration of anti-bovine serum albumin IgG antibodies, in animals submitted to exhaustion test and a three-hour recovery period. There was no effect of training and supplementation on the response to DTH. Supplemented animals presented greatest plasma glutamine concentration (p<0.05, though this increase in glutaminemia did not interfere on the serum IgG antibody concentration. The recovery period after intense exercise resulted in decreased glutaminemia as compared with the values obtained immediately after exhaustion test (p<0.05.

    Full Text Available Context: Novel psychoactive substances, including synthetic cannabinoids, are becoming increasingly popular, with more patients being seen in the emergency room following acute ingestion. These substances have been associated with a wide range of adverse effects. However, identification of complications, clinical toxicity, and management remain challenging. Case Report: We present the case of a young African-American male who developed severe agitation and bizarre behavior following acute K2 ingestion. Laboratory studies revealed markedly elevated serum creatine phosphokinase (CPK with normal renal function. The patient was managed with aggressive intravenous (IV fluid hydration and treatment of underlying psychiatric illness. Conclusion: We recommend the routine evaluation of renal function and CPK levels with early initiation of IV hydration among patients who present to the emergency department following acute ingestion of synthetic cannabinoids to identify potential complications early as well as institute early supportive therapy.

    Full Text Available We evaluated the effects of the supplementation with L-glutamine and glutamine dipeptide (GDP on biochemical and morphophysiological parameters in streptozotocin-diabetic rats. For this purpose, thirty animals were distributed into six groups treated orally (gavage during thirty days: non diabetic rats (Control + saline, diabetic + saline; Control + L-glutamine (248 mg/kg, Diabetic + L-glutamine (248 mg/kg, Control + GDP (400 mg/kg, Diabetic + GDP (400 mg/kg. Diabetes was induced by an intravenous injection of streptozotocin (60 mg/kg and confirmed by fasting glucose ≥ 200 mg/dL. Physiological parameters, i.e., body mass, food intake, blood glucose, water intake, urine and faeces were evaluated during supplementation. After the period of supplementation, the animals were euthanized. The blood was collected for biochemical assays (fructosamine, transaminases, lipid profile, total protein, urea, ammonia. Moreover, the jejunum was excised and stored for morphophysiological assays (intestinal enzyme activity, intestinal wall morphology, crypt proliferative index, number of serotoninergic cells from the mucosa, and vipergic neurons from the submucosal tunica. The physiological parameters, protein metabolism and intestinal enzyme activity did not change with the supplementation with L-glutamine or GDP. In diabetic animals, transaminases and fructosamine improved with L-glutamine and GDP supplementations, while the lipid profile improved with L-glutamine. Furthermore, both forms of supplementation promoted changes in jejunal tunicas and wall morphometry of control and diabetic groups, but only L-glutamine promoted maintenance of serotoninergic cells and vipergic neurons populations. On the other hand, control animals showed changes that may indicate negative effects of L-glutamine. Thus, the supplementation with L-glutamine was more efficient for maintaining intestinal morphophysiology and the supplementation with GDP was more efficient to the organism as a whole. Thus, we can conclude that local differences in absorption and metabolism could explain the differences between the supplementation with L-glutamine or GDP.

    The herbicide, pendimethalin, is used worldwide, but its acute toxicity is not yet widely known. There have been some reported acute pendimethalin poisoning cases in humans and most of them intentionally ingested the concentrated formulation. We describe a 73-year-old man who developed corrosive gastroduodenal injury after accidental ingestion of the diluted (300 times with water) pendimethalin formulation. He had a history of reflux oesophagitis and had been taking omeprazol (10 mg/day) for a year. He consumed alcohol two hours after the accidental ingestion and then had nausea and epigastric pain. Endoscopy performed three days post-exposure revealed gastroduodenal injury. As he had consumed alcohol every day for years and had no history of gastroduodenal ulcer, the accidental ingestion may be associated with this injury. He was successfully treated by increasing his dosage of omeprazol (20 mg/day) for two weeks. This case indicates that ingestion of a small quantity of pendimethalin can provoke gastroduodenal injury.

    Baking soda is a readily available household product composed of sodium bicarbonate. It can be used as a home remedy to treat dyspepsia. If used in excessive amounts, baking soda has the potential to cause a variety of serious metabolic abnormalities. We believe this is the first reported case of hemorrhagic encephalopathy induced by baking soda ingestion. Healthcare providers should be aware of the dangers of baking soda misuse and the associated adverse effects.

    Guaifenesin is a common nonprescription medication that has been implicated in drug-induced nephrolithiasis. Dextromethorphan, a nonprescription antitussive found in some guaifenesin-containing preparations, is increasingly recognized as a substance of abuse by many youth and young adults. Renally excreted medications known to have poor solubility in urine have the potential to precipitate when ingested in large quantity, leading to acute obstruction of the ureters and renal failure. We describe the case of a 22-year-old male who developed severe bilateral flank pain, hematuria, and oliguria after an isolated recreational ingestion of guaifenesin and dextromethorphan. The patient was found to have bilateral ureteral obstruction and acute renal failure, suspected to be secondary to precipitation of medication metabolites in the urine. This case highlights the potential for acute renal failure secondary to guaifenesin and dextromethorphan abuse. Copyright © 2014 Elsevier Inc. All rights reserved.

    Orthostatic tolerance is impaired following an acute bout of exercise. This study examined the effect of fluid ingestion following treadmill exercise in restoring the cardiovascular responses to an orthostatic stress. Five men (age, 29.6 +/- 3.4 yrs) were exposed to a graded lower body negative (LBNP) pressure protocol (0 to -50 mmHg) during euhydration without exercise (C), 20 minutes after exercise dehydration (D), 20 minutes after exercise and fluid ingestion (FI20), and 60 minutes after exercise and fluid ingestion (FI60). Fluid ingestion (mean +/- SE) consisted of water-ingestion equivalent to 50% of the body weight lost during exercise (520 +/- 15 ml). Exercise dehydration resulted in significantly higher heart rates (119 +/- 8 vs 82 +/- 7 bpm), lower systolic blood pressures (95 +/- 1.7 vs 108 +/- 2.3 mmHg), a smaller increase in leg circumference (3.7 +/- 4 vs 6.9 +/- 1.0 mm), and an attenuated increase in total peripheral resistance (2.58 +/- 1.2 vs 4.28 +/- 0.9 mmHg/L/min) at -50 mmHg LBNP compared to the C condition. Fluid ingestion (both 20 and 60), partially restored the heart rate, systolic blood pressure, and total peripheral resistance responses to LBNP, but did not influence the change in leg circumference during LBNP (4 +/- 0.3 for R20 and 2.8 +/- 0.4 mm for R60). These data illustrate the effectiveness of fluid ingestion on improving orthostatic responses following exercise, and suggest that dehydration is a contributing factor to orthostatic intolerance following exercise.

    We present a case of a non-Q wave myocardial infarction and acute renal failure following an ingestion of naphtha, a petroleum distillate composed primarily of hydrocarbons. The patient's renal, metabolic, and cardiac status improved over several days with aggressive volume replacement and bicarbonate therapy. Acute cardiotoxic effects of hydrocarbon exposure generally manifest as dysrhythmias, secondary to myocardial sensitization to circulating catecholamines, or, possibly, coronary vasospasm. Ischemia from associated hypotension or direct myocardial toxicity are other potential causes of naphtha-related cardiac injury.

    Xylitol is a five-carbon sugar alcohol produced from natural resources frequently used as a sugar substitute for humans. We report the development and successful treatment of acute hepatic failure and coagulopathy in a dog after xylitol ingestion. A 9-year-old 4.95 kg (10.9 lb) neutered male Chihuahua was evaluated at a veterinary clinic for vomiting after ingesting 224 g (45 g/kg, 20.5 g/lb) of granulated xylitol. Hypoglycemia developed within 1-2 h, elevated liver values, suggesting the development of acute hepatic failure, within 12 h and coagulopathy less than 24 h after ingestion. Treatment included maropitant, intravenous dextrose, phytonadione, metronidazole, and fresh frozen plasma. N-acetylcysteine (NAC) and S-adensoyl-L-methionine (SAMe) provided hepatic detoxification and support. The dog survived and liver values returned to normal within 1 month post ingestion. No adverse effects to hepatic function have been identified 2 years after acute xylitol toxicity. This paper is one of the few reports of successful management of a dog with hypoglycemia, hepatic failure, and coagulopathy caused by xylitol toxicity. To date, this is the highest published xylitol dose survived by a dog, as well as the only reported case that documents laboratory changes throughout the course of toxicity and includes normal hepatic indices for 7 months following xylitol toxicity. The rapidly expanding use of xylitol in a variety of products intended for human consumption has led to a rise in xylitol toxicity cases reported in dogs, and clinicians should be aware that more dogs may potentially be exposed and develop similar manifestations.

    Yohimbine is an alkaloid obtained from the Corynanthe yohimbe tree and other biological sources. Yohimbine is currently approved in the United States for erectile dysfunction and has undergone resurgence in street use as an aphrodisiac and mild hallucinogen. In recent years yohimbine use has become common in body-building communities for its presumed lipolytic and sympathomimetic effects. We describe a 37-year-old bodybuilder in which severe acute neurotoxic effects occurred in 2 h after yohimbine ingestion. The patient presented with malaise, vomiting, loss of consciousness, and repeated seizures after ingestion of 5 g of yohimbine during a body-building competition in a gymnasium. His Glasgow Coma Score was 3, requiring orotracheal intubation. Two hours after admission, vital signs were blood pressure 259/107 mmHg and heart rate 140 beats/min. Treatment with furosemide, labetalol, clonidine, and urapidil and gastrointestinal decontamination were performed. Twelve hours later the patient was extubated with normal hemodynamic parameters and neurological examination. The yohimbine blood levels at 3, 6, 14, and 22 h after ingestion were 5,240; 2,250; 1,530; and 865 ng/mL, respectively, with a mean half-life of 2 h. Few data are available about yohimbine toxicity and the related blood levels. This is a case of a large ingestion of yohimbine in which severe hemodynamic and neurological manifestations occurred and elevated blood levels of yohimbine were detected.

    This chart review was undertaken to assess efficacy and safety of hydroxocobalamin for acute cyanide poisoning. Hospital records of the Fernand Widal and Lariboisière Hospitals were reviewed for intensive care unit admissions with cyanide poisoning for which hydroxocobalamin was used as first-line treatment from 1988 to 2003. Smoke inhalation cases were excluded. Hydroxocobalamin (5-20 g) was administered to 14 consecutive patients beginning a median 2.1 hours after cyanide ingestion or inhalation. Ten patients (71%) survived and were discharged. Of the 11 patients with blood cyanide exceeding the typically lethal threshold of 100 micromol/L, 7 survived. The most common hydroxocobalamin-attributed adverse events were chromaturia and pink skin discoloration. Severe cyanide poisoning of the nature observed in most patients in this study is frequently fatal. That 71% of patients survived after treatment with hydroxocobalamin suggests that hydroxocobalamin as first-line antidotal therapy is effective and safe in acute cyanide poisoning.

    An 82-year-old man presented with signs and symptoms that were suggestive of acute cholecystitis. He underwent a laparoscopic cholecystectomy. During the intervention, a wooden foreign body was removed from the infiltrated omentum, probably after it had perforated the gastric antrum. The gastric perforation had led to a secondary infection of the gallbladder. The presumed gastric perforation was treated conservatively, and the patient recovered well and was discharged after 7 days. Secondary inflamed gallbladders are rare; the current case is, to the best of our knowledge, the first case reporting a secondary infection of the gallbladder due to a gastric perforation. Clinicians should be aware of possible ingestion of foreign bodies in elderly patients wearing dental prosthetic devices.

    Full Text Available The powder of henna plant (Lawsonia inermis Linn. is extensively used as a decorative skin paint for nail coloring and as a hair dye. Most reports of henna toxicity have been attributed to adding a synthetic dye para-phenylenediamine (PPD. PPD is marketed as black henna added to natural henna to accentuate the dark color and shorten the application time. PPD toxicity is well known and extensively reported in medical literature. We report a case of a young Saudi male who presented with characteristic features of acute renal failure and intravascular hemolysis following ingestion of henna mixture. Management of PPD poisoning is only suppor-tive and helpful only if instituted early. Diagnosis requires a high degree of clinical suspicion, as the clinical features are quite distinctive.

    Parenchymal changes within the brain in chronic alcoholics are well known, and specific MRI and MR spectroscopy findings have been described. However, recent alcohol ingestion goes undetected on routine MRI because of lack of specific parenchymal changes in the acute setting. Magnetic resonance spectroscopy can detect the presence of ethanol as a metabolite in the brain accurately and can provide valuable information regarding acute ingestion of alcohol. This may be useful especially in cases where history of alcohol ingestion is withheld.

    Euphorbia paralias is known in traditional medicine as an anti-inflammatory agent, a purgative and for its local anesthetic property. To the best our knowledge, renal toxicity of this substance has not been previously reported. In this paper, we report the case of a 29-year-old male who developed renal damage following ingestion of Euphorbia paralias. He had been on follow-up for nephrotic syndrome since 1986, although irregularly, with several relapses but each responding well to steroid therapy. A kidney biopsy had not been performed earlier due to refusal by the patient. He was off steroids since April 2008 because the patient developed osteoporosis. He was admitted with general malaise and oliguria to our department in May 2009, following repeated vomiting and watery diarrhea for three days. On examination, he was edematous but had normal vital signs except for a pulse rate of 120/min. Hemoglobin was only 5.5 g/dL but with normal white cell and platelet counts. Blood biochemistry showed evidence of advanced renal failure with a serum creatinine level of 1835 μmol/L and urea at 44.6 mmol/L, sodium of 132 μmol/L and potassium at 4.3 mmol/L. He had features of nephrotic syndrome with severe hypoproteinamia and 24-h urinary protein of 10.45 g. Ultrasonography revealed enlarged kidneys with a reduced echogenecity of the medulla and the papillae. Subsequently, after hemodialysis with blood transfusion, a kidney biopsy was performed that showed focal segmental glomerulosclerosis associated with an acute tubular injury. On intensive interrogation, the patient gave a history of ingesting boiled Euphorbia paralias as a native treatment for edema, ten days prior to the onset of the current illness. A diagnosis of acute renal failure (ARF) resulting from the possible nephrotoxic effect of Euphorbia paralias poisoning was made. He was treated with intermittent hemodialysis and corticosteroids. Serum creatinine values improved after 48 days. At six months following the

    A test meal (300 mg casein, 600 mg sucrose, 100 mg corn oil, tracer dose of 9.10(3)H oleic acid) was given to fasting adult rats with intestinal lymph fistulas. One group received an acute oral dose of ethanol (3.2 g/kg body weight) simultaneously with the test meal. Controls received 2.5 ml of water instead of ethanol. Ingestion of ethanol temporarily delayed the removal of lipid radioactivity from the stomachs. More than 25% of radioactivity fed remained 8 hr after feeding whereas with control rats less than 10% of lipid radioactivity fed remained 6 hr after feeding. In controls and ethanol-treated rats, the amounts of exogenous lipids in the intestinal lumen and mucosa were low and similar enough. Quantities of endogenous and exogenous lipids found in the lymph collected during 24 hr after feeding were similar in the two groups, but the fat absorption peak was found after 6 hr in alcoholic rats and before 6 hr in controls. This delay was probably due to the retention of lipids in the stomach. More of the exogenous lipid was always transported by small particles moving in the region of alpha1 globulins in cellulose acetate electrophoresis than by larger particles remaining at the origin. This proportion was enhanced in the ethanol-treated animals. The larger fat particles were richer in endogenous fatty acids in alcohol-treated rats than in controls.

Methods After giving informed consent, twenty healthy men and women were randomly assigned to ingest 12 ounces of Celsius™ and, on a separate day, 12 ounces of Diet Coke®. All subjects completed both trials using a randomized, counterbalanced design. Metabolic rate (via indirect calorimetry and substrate oxidation (via respiratory exchange ratio were measured at baseline (pre-ingestion and at the end of each hour for 3 hours post-ingestion. Results Two-way ANOVA revealed a significant interaction (p ® ingestion. No differences in respiratory exchange ratio were noted between trials. Conclusion These preliminary findings indicate Celsius™ has thermogenic properties when ingested acutely. The effects of repeated, chronic ingestion of Celsius™ on body composition are unknown at this time.

    Inorganic nitrate ingestion has been posited to affect arterial blood pressure and vascular function. We sought to determine the acute effect of a red spinach extract (RSE) high in inorganic nitrate on vascular reactivity 1-h after ingestion in peripheral conduit and resistance arteries. Fifteen (n = 15; males 8, females 7) apparently healthy subjects (aged 23.1 ± 3.3 years; BMI 27.2 ± 3.7 kg/m(2)) participated in this crossover design, double-blinded study. Subjects reported to the lab ≥2-h post-prandial and consumed RSE (1000 mg dose; ~90 mg nitrate) or placebo (PBO). Venipuncture was performed on three occasions: baseline, 30-min post-ingestion and between 65 to 75-min post-ingestion. Baseline vascular measurements [i.e., calf venous occlusion plethysmography, brachial artery flow-mediated dilation (FMD)], 30-min of continuous blood pressure (BP) and heart rate (HR) analysis, and follow-up vascular measurements beginning at 40-min post-ingestion were also performed. Humoral nitrate following RSE ingestion was significantly higher at 30- (+54 %; P = 0.039) and 65 to 75-min post-ingestion compared to baseline (+255 %, P RSE ingestion, whereas it decreased (-14.0 %; P = 0.008) following PBO ingestion. No significant differential FMD responses were detected (P > 0.05), though RH was decreased following the baseline measure in both conditions. RSE significantly increased plasma nitrate 30-min post-ingestion, but acute microvascular (i.e., resistance vasculature) reactivity increases were isolated to the lower limb and no appreciable change in brachial artery FMD was observed.

None of two groups of volunteers (7 males, 4 females showed clear alterations of the insulin binding parameters (Ka and R0), or of the fasting cortisol, glucose and insulin concentrations. These results exclude the possibility that the diabetogenic effect of glucocorticoides is accompanied by an alteration of the insulin receptor characteristics of erythrocytes.

    Manganese is a ubiquitous, essential trace element and a common ingredient of joint supplement tablets. Little information is known about the inherent toxic potential if ingested at higher doses. A 5-year-old female spayed Pug dog presented for evaluation of vomiting and ataxia after accidental ingestion of approximately 100 joint supplement tablets. The dog developed acute hepatic failure and was euthanized 6 days after presentation due to progression of the disease. Necropsy showed severe acute hepatic necrosis. Liver and kidney samples were submitted for toxicology analysis, results of which showed severely elevated manganese concentrations in the liver and kidneys.

    Sewing machine oil ingestion is rare but is possible due to its availability at home. Chemically, it belongs to hydrocarbon family which is toxic if aspirated, owing to their physical properties such as high volatility and low viscosity. On the contrary, sewing machine lubricant has high viscosity and low volatility which makes it aspiration less likely. The main danger of hydrocarbon ingestion is chemical pneumonitis which may be as severe as acute respiratory distress syndrome (ARDS). We report a case of a 5-year-old girl with accidental ingestion of sewing machine lubricant oil, who subsequently developed ARDS refractory to mechanical ventilation. There was much improvement with airway pressure release ventilation mode of ventilation, but the child succumbed to death due to pulmonary hemorrhage.

    Arterial stiffness increases after glucose ingestion. Acute low- and moderate-intensity aerobic exercise decreases arterial stiffness. However, the acute effects of 30 min of cycling at low- and moderate-intensity [25% (LE trial) and 65% (ME trial) peak oxygen uptake, respectively] on arterial stiffness at 30, 60 and 120 min of a postexercise glucose ingestion. Ten healthy young men (age, 22·4 ± 0·5 years) performed LE and ME trials on separate days in a randomized controlled crossover fashion. Carotid-femoral (aortic) pulse wave velocity (PWV), femoral-ankle (leg) PWV, carotid augmentation index (AIx) and carotid blood pressure (BP) (applanation tonometry), brachial and ankle BP (oscillometric device), heart rate (HR) (electrocardiography), blood glucose (UV-hexokinase method) and blood insulin (CLEIA method) levels were measured at before (baseline) and at 30, 60 and 120 min after the 75-g OGTT. Leg PWV, ankle pulse pressure and BG levels significantly increased from baseline after the 75-g OGTT in the LE trial (P<0·05), but not in the ME trial. Insulin levels and HR significantly increased from baseline after the 75-g OGTT in both trials (P<0·05). Aortic PWV, carotid AIx, brachial BP and carotid BP did not change from baseline after the 75-g OGTT in both trials. The present findings indicate that aerobic exercise at moderate intensity before glucose ingestion suppresses increases leg arterial stiffness after glucose ingestion.

    Acute bowel obstruction due to ingested foreign body (FB) like sharp bone fragment is a rare entity. As preoperative diagnosis was uncertain due to lack of proper history, diagnosis is usually done intraoperatively. Even though it is rare, we should consider it as differential diagnosis in patients with recent dietary history. Herein, we are reporting a 38-year-old man, without any psychiatric illness or previous surgery presenting to emergency department with the features of acute bowel obstruction. CT scan shows high density object in ileum suspicious of foreign body. Patient underwent exploratory laparatomy which reveals dilated small bowel with sharp bony object in ileum, which was retrieved with enterotomy.

    Isohumulones, principal components of the bitter taste of beers, have antioxidant capacity. We studied i) the effects of oral ingestion of isomerized hop extract (IHE) on the endothelial functions in smokers as well as non-smokers and ii) the effects of IHE on cultured endothelial cells in high oxidative stress state. Twelve cigarette smokers and eleven non-smokers ingested IHE and placebo in a randomized crossover design. Flow-mediated vasodilatation (FMD) was measured using ultrasonography. We also studied the effects of isohumulones on i) the cell viability under hypoxia and ii) the levels of angiotensin II (AT-II)-induced reactive oxygen species (ROS) in the cultured human aortic endothelial cells (HAECs). At baseline, the FMDs of the smokers were significantly lower than those of the non-smokers. The FMDs increased significantly after 30 min and 120 min of IHE ingestion in both the smokers and the non-smokers. IHE protected the HAECs from hypoxia-induced cell death as assessed by cell viability. IHE also reduced the AT-II-induced intracellular ROS level. Oral ingestion of IHE appears to exert acute beneficial effects on the endothelial functions in both the smokers and non-smokers, and the in vitro experiments using HAECs suggested that the effect be through reducing intracellular oxidative stress.

    Dietary supplements inducing alkalosis have been shown to be ergogenic during intense endurance exercise in temperate environments, but there is lack of data regarding the efficacy of these substances in the heat. This study aimed to investigate the effect of sodium citrate (CIT) ingestion on 5,000-m running performance in a warm environment. Sixteen non-heat-acclimated endurance-trained males (age 25.8 ± 4.4 years, VO2peak 56.9 ± 4.7 mL kg min) completed two 5,000-m self-paced treadmill runs with preceding CIT or placebo (wheat flour; PLC) ingestion in a double-blind, randomized, crossover manner in a climatic chamber (air temperature 32 °C, relative humidity 50 %). CIT ingestion (500 mg kg(-1) body mass) compared to PLC induced increases in water retention, body mass and plasma volume (P rate, heart rate and 5,000-m running time (18.92 ± 2.05 min in CIT, 19.11 ± 2.38 min in PLC; 66 % likelihood of benefit, d = -0.09) were similar (P > 0.05) in the two trials. Post-exercise blood lactate concentration was higher (P 0.05). Acute CIT ingestion induces alkalosis, water retention, plasma volume expansion and an increase in post-exercise blood lactate concentration, but does not improve 5,000-m running performance in a warm environment in non-heat-acclimated endurance-trained males.

    We describe the case of a 6-year-old girl brought to the emergency department for the sudden onset of anticholinergic syndrome after the ingestion of a few home-made partially debittered lupine beans. She complained of blurry vision, headache, photophobia and nausea. No specific treatment was needed, and the symptoms resolved about 12 h after the exposure. Lupine beans are a popular and worldwide-diffused food. The bitter variety is rich in alkaloids harbouring anticholinergic activity and thus requires a debittering process before lupines can be eaten. Only four cases of acute toxicity, due to the ingestion of incompletely detoxified bitter lupines, have been reported in children so far; notwithstanding the small amount of lupines ingested, three of these cases were lethal. Acute anticholinergic syndrome can arise after the consumption of a wide range of exogenous substances including partially debittered lupine beans. Paediatricians should be aware of bitter lupine toxicity, recognize possible cases of intoxication, ensure a prompt and appropriate supportive treatment and provide appropriate information about their danger.

    Erythrocyte deformability is an important property of erythrocytes that considerably affects blood flow and hemodynamics. The high content of polyphenols present in dark chocolate has been reported to play a protective role in functionality of erythrocytes. We hypothesized that chocolate might influence erythrocytes not only after repeated chronic intake, but also immediately after its ingestion. Thus, we determined the acute effect of dark chocolate and milk (with lower content of biologically active substances) chocolate intake on erythrocyte deformability. We also focused on selected factors that may affect erythrocyte deformability, specifically nitric oxide production in erythrocytes and total antioxidant capacity of plasma. We determined posttreatment changes in the mentioned parameters 2hours after consumption of chocolate compared with their levels before consumption of chocolate. In contrast to milk chocolate intake, the dark chocolate led to a significantly higher increase in erythrocyte deformability. Nitric oxide production in erythrocytes was not changed after dark chocolate intake, but significantly decreased after milk chocolate. The plasma total antioxidant capacity remained unaffected after ingestion of both chocolates. We conclude that our hypothesis was confirmed. Single ingestion of dark chocolate improved erythrocyte deformability despite unchanged nitric oxide production and antioxidant capacity of plasma. Increased deformability of erythrocytes may considerably improve rheological properties of blood and thus hemodynamics in humans, resulting in better tissue oxygenation.

    In epidemiological studies, chronic dairy milk consumption is associated with improved vascular health and reduced age-related increases in blood pressure. Although milk protein supplementation augments conduit artery flow-mediated dilation, whether or not acute dairy milk intake may improve microvascular function remains unclear. We hypothesised that dairy milk would increase direct measurement of endothelial nitric oxide (NO)-dependent cutaneous vasodilation in response to local skin heating. Eleven men and women (61 (sem 2) years) ingested two or four servings (473 and 946 ml) of 1 % dairy milk or a rice beverage on each of 4 separate study days. In a subset of five subjects, an additional protocol was completed after 473 ml of water ingestion. Once a stable blood flow occurred, 15 mm-N G -nitro-l-arginine methyl ester was perfused (intradermal microdialysis) to quantify NO-dependent vasodilation. Red-blood-cell flux (RBF) was measured by laser-Doppler flowmetry, and cutaneous vascular conductance (CVC=RBF/mean arterial pressure) was calculated and normalised to maximum (%CVCmax; 28 mm-sodium nitroprusside). Full expression of cutaneous vasodilation was not different among dairy milk, rice beverage and water, and there was no effect of serving size on the total vasodilatory response. Contrary to our hypothesis, NO-dependent vasodilation was lower for dairy milk than rice beverage (D: 49 (sem 5), R: 55 (sem 5) %CVCmax; Pdairy milk ingestion does not augment NO-dependent vasodilation in the cutaneous microcirculation compared with a rice beverage control.

    Evaluating the function of the vestibular part of the inner ear comprises more than the classic analysis of the lateral semicircular canal function. In healthy subjects, positional alcohol nystagmus may be seen after acute alcohol ingestion. Posturography has shown a deteriorated equilibrium after even moderate doses of alcohol, which speculatively could be an effect of otolith disturbance or a central integrative effect. We tested the possibility of an otolith effect by using linear acceleration in the lateral direction by means of eccentric rotation, stimulating mainly the outermost ear's otolith organ. The subject is seated eccentrically in a rotatory chair facing the direction of rotation. Thus, the otolith organs are stimulated in steady-state rotation. The subject experiences a lateral tilt and, in darkness, is instructed to put a short light bar in the position thought to be that of a water surface, which is identical to the perceived tilt. Twenty healthy subjects (10 men, 10 women) aged 20-29 years were tested before and approximately 1 hour after ingestion of alcohol, the amounts consumed corresponding to an approximate blood alcohol level of 0.05%, well above the maximum permissible level for driving in Sweden. No significant effects of alcohol were found. The otolith function probably is not affected by moderate alcohol intoxication levels. From this point of view, equilibrium deterioration due to alcohol ingestion in the erect position is caused by a central integrative deficit and not by an otolith effect.

    Caustic ingestions (alkalis, acids) may cause severe chemical burns and lifelong complications, which worsen life quality. Approximately 80% of caustic ingestions occur in children. They mostly intoxicate because of chemical substances kept insecurely or in inappropriate containers. Until now, there is no general opinion about diagnostics and management of caustic ingestions. Therefore, the main aim of this article is accurately represent diagnostic and treatment options believing that this information would help physicians to diagnose caustic ingestions easier and faster, to provide emergency management correctly, and to avoid acute and chronic complications.

  7. A Systematic Review of Fatalities Related to Acute Ingestion of Salt. A Need for Warning Labels?

    Campbell, Norm R C; Train, Emma J

    2017-06-23

    There are sporadic cases of fatalities from acutely eating salt. Yet, on social media, there are "challenges to" and examples of children and some adults acutely eating salt, and recently a charity advocated eating small amounts of salt to empathize with Syrian refugees. We performed a systematic review of fatalities from ingesting salt to assess if relatively moderate doses of salt could be fatal. In 27 reports, there were 35 fatalities documented (19 in adults and 16 in children). The lethal dose was estimated to be less than 10 g of sodium (<5 teaspoons of salt) in two children, and less than 25 g sodium in four adults (<4 tablespoons of salt). The frequency of fatal ingestion of salt is not able to be discerned from our review. If investigation of the causes of hypernatremia in hospital records indicates salt overdose is relatively common, consideration could be given to placing warning labels on salt containers and shakers. Such warning labels can have the added advantage of reducing dietary salt consumption.

    Full Text Available Background : Chronic damage to the central nervous system resulting in cognitive impairment has been shown with repeated, low doses of organophosphorus (OP exposure over month or years. Aim: The study aimed to find out whether there is any cognitive impairment following acute OP exposure that could be detected by a simple screening instrument, the Mini Mental State Examination (MMSE, in clinical settings. Settings and Design: A cohort study. Materials and Methods: The study was conducted with matched controls. Consecutive patients admitted to the hospital with acute ingestion of OP were recruited. Cognitive function was assessed with the MMSE, digit span test, test of long-term memory function and concentration. Patients were assessed twice: at 1 and 6 weeks of exposure. Statistical Analysis: Continuous variables were analyzed with the paired and unpaired T-tests. Non-normally distributed data were analyzed with the Mann-Whitney U test and Wilcoxon Signed Rank test. Discrete variables were analyzed with the Chi-square test. Results: There were 60 patients and 61 controls. The mean age (SD of the patients and controls was 31.5 (11.6 and 31.3 (11.8 years, respectively. Forty-two patients turned up for the second assessment. Significant impairment of cognitive function was seen in the total score of MMSE (95% CI -2.5 to -0.3, orientation (95% CI -1 to -0.2 and language (95% CI -0.9 to -0.1 domains of MMSE, digit span test (95% CI 0.1-1.7 and test of long-term memory function (95% CI 0.3-2.3 in the first assessment compared with the controls. When the results of the second assessment were compared with the controls, no significant differences were seen. Conclusion: Although there was a slight transient cognitive impairment detected with the screening tests following acute OP ingestion, no long-term cognitive defects was detected.

    Full Text Available Previous research has revealed that glucose and fructose ingestion differentially modulate release of satiation hormones. Recent studies have begun to elucidate brain-gut interactions with neuroimaging approaches such as magnetic resonance imaging (MRI, but the neural mechanism underlying different behavioral and physiological effects of glucose and fructose are unclear. In this paper, we have used resting state functional MRI to explore whether acute glucose and fructose ingestion also induced dissociable effects in the neural system. Using a cross-over, double-blind, placebo-controlled design, we compared resting state functional connectivity (rsFC strengths within the basal ganglia/limbic network in 12 healthy lean males. Each subject was administered fructose, glucose and placebo on three separate occasions. Subsequent correlation analysis was used to examine relations between rsFC findings and plasma concentrations of satiation hormones and subjective feelings of appetite. Glucose ingestion induced significantly greater elevations in plasma glucose, insulin, GLP-1 and GIP, while feelings of fullness increased and prospective food consumption decreased relative to fructose. Furthermore, glucose increased rsFC of the left caudatus and putamen, precuneus and lingual gyrus more than fructose, whereas within the basal ganglia/limbic network, fructose increased rsFC of the left amygdala, left hippocampus, right parahippocampus, orbitofrontal cortex and precentral gyrus more than glucose. Moreover, compared to fructose, the increased rsFC after glucose positively correlated with the glucose-induced increase in insulin. Our findings suggest that glucose and fructose induce dissociable effects on rsFC within the basal ganglia/limbic network, which are probably mediated by different insulin levels. A larger study would be recommended in order to confirm these findings.

    Acetaminophen (paracetamol) is a commonly used over-the-counter analgesic and antipyretic and has previously been shown to improve exercise performance through a reduction in perceived pain. This study sought to establish whether its antipyretic action may also improve exercise capacity in the heat by moderating the increase in core temperature. On separate days, 11 recreationally active participants completed two experimental time-to-exhaustion trials on a cycle ergometer in hot conditions (30°C, 50% relative humidity) after ingesting a placebo control or an oral dose of acetaminophen in a randomized, double-blind design. Following acetaminophen ingestion, participants cycled for a significantly longer period of time (acetaminophen, 23 ± 15 min versus placebo, 19 ± 13 min; P = 0.005; 95% confidence interval = 90-379 s), and this was accompanied by significantly lower core (-0.15°C), skin (-0.47°C) and body temperatures (0.19°C; P 0.05). This is the first study to demonstrate that an acute dose of acetaminophen can improve cycling capacity in hot conditions, and that this may be due to the observed reduction in core, skin and body temperature and the subjective perception of thermal comfort. These findings suggest that acetaminophen may reduce the thermoregulatory strain elicited from exercise, thus improving time to exhaustion.

    Full Text Available Ingestion of foreign bodies is not an uncommon occurrence, but most of them will pass through the gastrointestinal tract without consequences. Complication such as perforation is rare. We present a case of small bowel perforation secondary to the accidental ingestion of a chicken bone. The patient presented with abdominal pain, constipation and vomiting. Clinical examination confirmed generalized abdominal tenderness and rebound tenderness. Abdominal radiography showed multiple dilated loops of small bowel, and abdominal ultrasound (US showed inflammatory changes on small bowel loops, with free fluid and fluid collection around intestinal loops. The patient underwent an emergency laparotomy. Intra operative findings revealed diffuse fibro purulent peritonitis with abscess between central small bowels loops. At about 60 cm from Bauchini valve we found a perforation of ileum at the anti-mesenteric site caused by a sharp chicken wishbone. The patient was treated with resection of the ileum segment (10 cm and primary end-to-end anastomosis. Even that intestinal perforation by a foreign body is rare, physicians should consider possibility of intestinal perforation by a foreign body in the differential diagnosis of acute abdomen in patients presenting with abdominal pain.

    This pilot study aimed to investigate the effect of simple sugar ingestion, in amounts typical of common ingestion, on appetite and the gut-derived hormone response. Seven healthy men ingested water (W) and equicaloric solutions containing 39.6 g glucose monohydrate (G), 36 g fructose (F), 36 g sucrose (S), and 19.8 g glucose monohydrate + 18 g fructose (C), in a randomised order. Serum concentrations of ghrelin, glucose dependent insulinotropic polypeptide (GIP), glucagon like peptide-1 (GLP-1), insulin, lactate, triglycerides, non-esterified fatty acids (NEFA), and d-3 hydroxybutyrate, were measured for 60 min. Appetite was measured using visual analogue scales (VAS). The ingestion of F and S resulted in a lower GIP incremental area under the curve (iAUC) compared to the ingestion of G (p < 0.05). No differences in the iAUC for GLP-1 or ghrelin were present between the trials, nor for insulin between the sugars. No differences in appetite ratings or hepatic metabolism measures were found, except for lactate, which was greater following the ingestion of F, S, and C, when compared to W and G (p < 0.05). The acute ingestion of typical amounts of fructose, in a variety of forms, results in marked differences in circulating GIP and lactate concentration, but no differences in appetite ratings, triglyceride concentration, indicative lipolysis, or NEFA metabolism, when compared to glucose.

    Acute exogenous lipoid pneumonia is an uncommon condition caused by aspiration of oil-based substances, occurring mainly in children. Here, we report the case of an 83-year-old patient with Alzheimer's disease who presented with coughing and hypoxia. The diagnosis of acute exogenous lipoid pneumonia caused by accidental kerosene ingestion was made on the basis of the patient's clinical history, and typical radiological and cytological findings. The patient's cognitive impairment and an unsafe environment, in which the patient's 91-year-old husband stored kerosene in an old shochu bottle, were responsible for the accidental ingestion. Acute exogenous lipoid pneumonia should be considered in the differential diagnosis for acute respiratory disorders in the rapidly aging population. © 2013 Japan Geriatrics Society.

    Full Text Available Abstract Background The purpose of this study was to examine the acute effects of a weight loss supplement on resting oxygen uptake (VO2, respiratory quotient (RQ, caloric expenditure (kcal, heart rate (HR, and blood pressure (BP in healthy and physically active individuals. Methods Ten subjects (5 male, 5 female; 20.2 ± 1.2 y; 172.2 ± 8.9 cm; 71.5 ± 17.2 kg; 17.3 ± 2.6% body fat underwent two testing sessions administered in a randomized and double-blind fashion. During each session, subjects reported to the Human Performance Laboratory after at least 3-h post-absorptive state and were provided either 3 capsules of the weight loss supplement (SUP, commercially marketed as Meltdown® or 3 capsules of a placebo (P. Subjects then rested in a semi-recumbent position for three hours. VO2 and HR were determined every 5 min during the first 30 min and every 10 min during the next 150 min. BP was determined every 15 min during the first 30 min and every 30 min thereafter. The profile of mood states was assessed every 30 min. Results Area under the curve analysis revealed a significant 28.9% difference in VO2 between SUP and P for the three hour study period. In addition, a significant difference in energy expenditure was also seen between SUP (1.28 ± 0.33 kcal·min-1 and P (1.00 ± 0.32 kcal·min-1. A trend (p = 0.06 towards a greater utilization of stored fat as an energy source was also demonstrated (0.78 ± 0.23 kcal·min-1 and 0.50 ± 0.38 kcal·min-1 in P and SUP, respectively. Significant elevations in HR were seen during hours two and three of the study, and significantly higher average systolic BP was observed between SUP (118.0 ± 7.3 mmHg and P (111.4 ± 8.2 mmHg. No significant differences were seen in diastolic blood pressure at any time point. Significant increases in tension and confusion were seen in SUP. Conclusion Results indicate a significant increase in energy expenditure in young, healthy individuals following an acute

    2011-06-01

    Full Text Available Abstract Introduction The consumption of energy drinks has increased significantly. We report the case of a patient who presented to our hospital with jaundice, abdominal pain, and markedly increased liver transaminases likely due to the increased consumption of an energy drink. To the best of our knowledge, this is the first case report in the literature linking the development of acute hepatitis to the consumption of an energy drink. Case presentation A 22-year-old Caucasian woman presented to our hospital with epigastric pain, nausea, vomiting, and low-grade fever. She had been drinking 10 cans of an energy drink daily for two weeks prior to presentation. Her physical examination revealed mild epigastric tenderness. Her initial blood tests revealed elevated alanine aminotransferase, aspartate aminotransferase, and total bilirubin. A computed tomographic scan of the abdomen and pelvis was normal, and the patient was discharged to home. She returned to the Emergency Department of our hospital with worsening pain and new-onset jaundice. This time her physical examination revealed epigastric tenderness and icteric sclera. Her aspartate aminotransferase, alanine aminotransferase, and international normalized ratio were markedly elevated. Further radiological studies were non-specific, and she was admitted to our hospital with a diagnosis of acute hepatitis. Her viral serology and toxicology screens were negative. The patient was treated supportively and was discharged after resolution of her symptoms and a marked decrease in her liver enzymes. Conclusion The development of acute hepatitis in this patient was most likely due to the excessive ingestion of an energy drink, and we speculate that niacin was the culprit ingredient.

    This study investigated the effect of acute caffeine (CAF) intake on postexercise oxygen consumption (EPOC) after intense resistance training. Fourteen strength-trained men (mean ± SD age and mass =23.1 ± 4.2 yr and 83.4 ± 13.2 kg, respectively) who were caffeine users initially completed one-repetition maximum testing (1-RM) of four exercises: bench press, leg press, lat row, and shoulder press. On each of two days separated by one week, they completed four sets of each exercise to fatigue at 70-80% 1-RM, which was preceded by ingestion of CAF (6 mg/kg) or placebo. Pre-exercise, indirect calorimetry was used to assess energy expenditure for 35 min; this was repeated for 75 min postexercise while subjects remained seated in a quiet lab. Two-way analysis of variance with repeated measures was used to examine differences in gas exchange variables across time and treatment. Results revealed that EPOC was significantly higher (PEPOC and energy expenditure pre-and post-exercise, yet the magnitude of this effect is relatively small.

    The efficacy of caffeine ingestion in enhancing aerobic performance is well established. However, despite suggestions that caffeine may enhance resistance exercise performance, research is equivocal on the effect of acute caffeine ingestion on resistance exercise performance. It has also been suggested that dampened perception of perceived exertion and pain perception might be an explanation for any possible enhancement of resistance exercise performance due to caffeine ingestion. Therefore, the aim of this study was to examine the acute effect of caffeine ingestion on repetitions to failure, rating of perceived exertion (RPE) and muscle pain perception during resistance exercise to failure. Eleven resistance trained individuals (9 males, 2 females, mean age±SD=26.4±6.4 years), took part in this double-blind, randomised cross-over experimental study whereby they ingested a caffeinated (5 mg kg(-1)) or placebo solution 60 minutes before completing a bout of resistance exercise. Experimental conditions were separated by at least 48 hours. Resistance exercise sessions consisted of bench press, deadlift, prone row and back squat exercise to failure at an intensity of 60% 1 repetition maximum. Results indicated that participants completed significantly greater repetitions to failure, irrespective of exercise, in the presence of caffeine (p=0.0001). Mean±S.D of repetitions to failure was 19.6±3.7 and 18.5±4.1 in caffeine and placebo conditions, respectively. There were no differences in peak heart rate or peak blood lactate values across conditions (both p >0.05). RPE was significantly lower in the caffeine compared to the placebo condition (p=0.03) and was significantly higher during lower body exercises compared to upper body exercises irrespective of substance ingested (p=0.0001). For muscle pain perception, a significant condition by exercise interaction (p=0.027) revealed that muscle pain perception was lower in the caffeine condition, irrespective of exercise

    Fructose intake has increased concurrent with sugar intake and this increase has been implicated in contributing to the development of metabolic syndrome risk factors. Recent evidence suggests a role for uric acid (UA) as a potential mediator via suppression of nitric oxide (NO) bioavailability. The aim of this study was to explore this hypothesis by measuring changes in UA concentration and systemic NO bioavailability as well as endothelial function in response to acute ingestion of a glucose-fructose beverage. Ten young (26.80 +/- 4.80 years), non-obese (body mass index: 25.1 +/- 2.55 kg m(-2); percent body fat: 13.5 +/- 6.9%) male subjects ingested either a glucose (100 g dextrose in 300 mL) or isocaloric glucose-fructose (glucose : fructose; 45 : 55 g in 300 mL) beverage. Blood was sampled pre- and every 15-min post-ingestion per 90 min and assayed for glucose, lactate, fructose, total nitrate/nitrate, UA and blood lipids. Forearm blood flow and pulse-wave velocity were recorded prior to and at 30 and 45 min time intervals post-ingestion, respectively, while heart rate, systolic and diastolic blood pressure were recorded every 15 min. The glucose-fructose ingestion was associated with a significant (P glucose-only ingestion. However, UA was not significantly different (P = 0.08) between conditions (AUC: -1018 +/- 1675 vs. 2171 +/- 1270 micromol L(-1) per 90 min for glucose and glucose-fructose conditions respectively). Consequently, no significant (P fructose-containing beverage was not associated with significantly altered UA concentration, endothelial function or systemic NO bioavailability.

    Full Text Available Abstract Background Oxalosis is a metabolic disorder characterized by deposition of oxalate crystals in various organs including the kidney. Whereas primary forms result from genetic defects in oxalate metabolism, secondary forms of oxalosis can result from excessive intestinal oxalate absorption or increased endogenous production, e.g. after intoxication with ethylene glycol. Case presentation Here, we describe a case of acute crystal-induced renal failure associated with excessive ingestion of rhubarb in a type 1 diabetic with previously normal excretory renal function. Renal biopsy revealed mild mesangial sclerosis, but prominent tubular deposition of oxalate crystals in the kidney. Oxalate serum levels were increased. Conclusion Acute secondary oxalate nephropathy due to excessive dietary intake of oxalate may lead to acute renal failure in patients with preexisting renal disease like mild diabetic nephropathy. Attention should be payed to special food behaviors when reasons for acute renal failure are explored.

    Studies suggest cardioprotective benefits of dark chocolate containing cocoa. This study examines the acute effects of solid dark chocolate and liquid cocoa intake on endothelial function and blood pressure in overweight adults. Randomized, placebo-controlled, single-blind crossover trial of 45 healthy adults [mean age: 53 y; mean body mass index (in kg/m(2)): 30]. In phase 1, subjects were randomly assigned to consume a solid dark chocolate bar (containing 22 g cocoa powder) or a cocoa-free placebo bar (containing 0 g cocoa powder). In phase 2, subjects were randomly assigned to consume sugar-free cocoa (containing 22 g cocoa powder), sugared cocoa (containing 22 g cocoa powder), or a placebo (containing 0 g cocoa powder). Solid dark chocolate and liquid cocoa ingestion improved endothelial function (measured as flow-mediated dilatation) compared with placebo (dark chocolate: 4.3 +/- 3.4% compared with -1.8 +/- 3.3%; P cocoa: 5.7 +/- 2.6% and 2.0 +/- 1.8% compared with -1.5 +/- 2.8%; P cocoa compared with placebo (dark chocolate: systolic, -3.2 +/- 5.8 mm Hg compared with 2.7 +/- 6.6 mm Hg; P cocoa: systolic, -2.1 +/- 7.0 mm Hg compared with 3.2 +/- 5.6 mm Hg; P cocoa (5.7 +/- 2.6% compared with 2.0 +/- 1.8%; P cocoa improved endothelial function and lowered blood pressure in overweight adults. Sugar content may attenuate these effects, and sugar-free preparations may augment them.

    Ortho-phenylphenol (OPP) and its sodium salt are used as fungicides and antibacterial agents, ingestion of which has been found to cause liver toxicity, renal toxicity and carcinomas in the urinary tract of rats. Lung damage due to OPP ingestion has not been reported in humans. We report a suicidal 39-year-old woman with stage II cervical cancer who drank a potentially lethal dose of OPP in the form of a commercial antiseptic, which led to the complication of liver and renal function impairment, severe lung damage with acute respiratory distress syndrome and subsequent severe lung fibrosis. Open lung biopsy showed diffuse alveolar damage. She was discharged after 34 days of hospitalization with continuing domiciliary oxygen therapy.

    Ingested type I IFN inhibits clinical attacks, relapses and inflammation in murine chronic relapsing EAE by inhibiting Th1-like cytokines. Type I IFN activates human suppressor T cells that produce SIRS. We examined whether oral (ingested) SIRS peptide inhibits EAE by decreasing Th1-like cytokines. Parenteral SIRS peptide 1-21 showed a significant inhibition of disease severity in murine EAE. Ingested SIRS peptide at 10 and 100 microg SIRS peptide showed a significant inhibition of disease severity but also a prolonged delay in the onset of disease compared to placebo. There were significantly less inflammatory foci in the SIRS peptide fed group compared to the control mock fed group. Splenocytes from SIRS peptide 1-21 fed mice showed increased production of Th2-like CD30L, IL-13, TCA-3 cytokines/chemokines and decreased production of Th1-like cytokine lymphotactin. Ingested (oral) SIRS peptide significantly inhibits both clinical EAE and inflammation predominately via counter-regulatory type 2-like cytokines/chemokines IL-13, CD30L and TCA-3.

    The intestinal absorption and metabolism of 385 micromol chlorogenic acids following a single intake of 200 mL of instant coffee by human volunteers with an ileostomy was investigated. HPLC-MS(3) analysis of 0-24h post-ingestion ileal effluent revealed the presence of 274+/-28 micromol of chlorogenic acids and their metabolites accounting for 71+/-7% of intake. Of the compounds recovered, 78% comprised parent compounds initially present in the coffee, and 22% were metabolites including free and sulfated caffeic and ferulic acids. Over a 24h period after ingestion of the coffee, excretion of chlorogenic acid metabolites in urine accounted for 8+/-1% of intake, the main compounds being ferulic acid-4-O-sulfate, caffeic acid-3-O-sulfate, isoferulic acid-3-O-glucuronide and dihydrocaffeic acid-3-O-sulfate. In contrast, after drinking a similar coffee, urinary excretion by humans with an intact colon corresponded to 29+/-4% of chlorogenic acid intake. This difference was due to the excretion of higher levels of dihydroferulic acid and feruloylglycine together with sulfate and glucuronide conjugates of dihydrocaffeic and dihydroferulic acids. This highlights the importance of colonic metabolism. Comparison of the data obtained in the current study with that of Stalmach et al. facilitated elucidation of the pathways involved in post-ingestion metabolism of chlorogenic acids and also helped distinguish between compounds absorbed in the small and the large intestine.

    The purpose of this study was to investigate the effect of ingestion of fluids with different carbohydrate concentrations (0, 1.5, and 7%) on the acute immune stress responses after high-intensity long-distance running. Continuous 18- to 20-km run was performed at 75% of maximal oxygen uptake with carbohydrate supplementation (CHO7%, 7% carbohydrate solution) and low-carbohydrate supplementation (lowCHO1.5%, 1.5% carbohydrate solution) in a randomized, double-blind, placebo (PLA) controlled design. Seven recreational runners (4 men and 3 women) completed all 3 trials. Blood was collected at baseline (PRE) and immediately after the run (POST). The running task induced significant (p ≤ 0.05) increases in leukocyte (white blood cells), neutrophil, and interleukin-6 (IL-6) counts in every trial. There was a significant (p ≤ 0.05) increase in cortisol with PLA and lowCHO1.5% but not with CHO7%. Increase in total leukocyte and neutrophil concentration was significantly lower with CHO7% compared with PLA (p ≤ 0.05). Postexercise IL-6 levels were significantly elevated when compared with baseline in all conditions (p ≤ 0.05). Interleukin-6 (IL-6) concentrations did not differ significantly between trials. LowCHO1.5% sport drink did not significantly differ from PLA in measured variables, which indicated that the amount and rate of carbohydrate ingestion (15 g, 10 g·h) in low-carbohydrate sport drink was not enough to significantly protect from the stress induced by high-intensity long-distance running, whereas the ingestion of CHO7% (45 g·h) blunted the significant cortisol response and significantly decreased the leukocyte response.

    Kerosene is a freely accessible hydrocarbon used in Sri Lankan (and other Asian) households for cooking and for lighting lamps. Kerosene poisoning is rarely reported among adults and its toxicological effects are not well known. Metformin is a commonly used oral hypoglycemic drug and its overdose leads primarily to lactic acidosis. Combined poisoning of metformin and kerosene and their interactions have not been reported. An 18-year-old, previously healthy, unmarried Sinhalese woman was referred following ingestion of 17.5 g of metformin and approximately 200 mL of kerosene oil in a suicide attempt. She had vomiting, burning epigastric pain, and a hypoglycemic seizure (capillary blood glucose of 42 mg/dL). Subsequently, she developed severe lactic acidosis followed by acute renal insufficiency, was treated with sodium bicarbonate, and underwent intermittent hemodialysis with bicarbonate. She recovered completely. This report proposes possible interactions that occur between metformin and kerosene that augment toxicity when the two are ingested together. It also stresses the importance of early treatment with intermittent hemodialysis in severe lactic acidosis with maintenance of blood glucose.

    Full Text Available Objective. To examine the endocrine response to a bout of heavy resistance exercise following acute β-hydroxy-β-methylbutyrate free acid (HMB-FA ingestion. Design. Twenty resistance trained men were randomized and consumed either 1 g of HMB-FA (BetaTor or placebo (PL 30 min prior to performing an acute heavy resistance exercise protocol. Blood was obtained before (PRE, immediately after (IP, and 30 min after exercise (30P. Circulating concentrations of testosterone, growth hormone (GH, insulin-like growth factor (IGF-1, and insulin were assayed. Data were analyzed with a repeated measures ANOVA and area under the curve (AUC was analyzed by the trapezoidal rule. Results. The resistance exercise protocol resulted in significant elevations from PRE in testosterone P<0.01, GH P<0.01, and insulin P=0.05 at IP, with GH P<0.01 and insulin P<0.01 remaining elevated at 30P. A significant interaction was noted between groups in the plasma GH response at IP, which was significantly higher following HMB-FA compared to PL P<0.01. AUC analysis revealed an elevated GH and IGF-1 response in the HMB-FA group compared to PL. Conclusion. HMB-FA prior to resistance exercise augments the GH response to high volume resistance exercise compared to PL. These findings provide further support for the potential anabolic benefits associated with HMB supplementation.

    Thai ginseng, Kaempferia parviflora, is widely believed among the Mong hill tribe to reduce perceived effort and improve physical work capacity. Kaempferia parviflora is consumed before their daily work. Therefore, we conducted an acute study on the effects of K. parviflora on repeated bouts of sprint exercise and on endurance exercise time to exhaustion. Two studies were conducted in college males using a randomized, double-blind, crossover design. Ninety minutes after consumption of K. parviflora or a starch placebo, participants in study 1 (n = 19) completed three consecutive maximum 30-s sprint cycling Wingate tests, separated by 3 min recovery, while participants in study 2 (n = 16) performed submaximal cycling exercise to exhaustion. Peak and mean power output decreased with successive Wingate tests, while percent fatigue and blood lactate concentration increased after the third Wingate test (P parviflora. There was also no effect of K. parviflora on time to exhaustion, rating of perceived exertion or heart rate during submaximal exercise. Our results indicate that acute ingestion of K. parviflora failed to improve exercise performance during repeated sprint exercise or submaximal exercise to exhaustion. However, chronic effects or actions in other populations cannot be excluded.

    A healthy diet involves eating fruit and vegetables on a daily basis, the benefits of which are in part linked to the ingestion of bioactive compounds including polyphenols. As a convenient means of delivering additional polyphenols to the diet, a polyphenol-rich (P-R) juice drink was prepared and the bioavailability of its diverse spectrum of constituents investigated. Ten human volunteers followed a low-flavonoid diet for 2 days before drinking 350 mL of the P-R beverage. Plasma and urine were collected for 24 h and analyzed by HPLC-PDA-MS. The plasma pharmacokinetics and recoveries of urinary metabolites of flavan-3-ols, flavanones, dihydrochalcones and 5-O-caffeoylquinic acid, both in terms of their identity and quantity, were, in most instances, not markedly different to those reported in other feeding studies with green tea, orange juice, apple cider and coffee. This indicates that the combination of polyphenolic compounds in the P-R beverage are absorbed and excreted to a similar extent whether fed individually or together in a single beverage. It is concluded that the P-R beverage can deliver the intended blend of bioavailable polyphenols, which would normally require consumption of several different plant-derived foods.

    Ten of 100 mature ewes were afflicted with acute oxalate toxicosis within 40 hours after being temporarily penned in a lot that contained considerable growing Rumex crispus (curly dock). Clinical signs of toxicosis included excess salivation, tremors, ataxia, and recumbency. Affected ewes were markedly hypocalcemic and azotemic. Oxalate crystals were not observed in urine. Gross postmortem lesions were minimal and nondiagnostic in 2 ewes that died peracutely, but perirenal edema and renal tubular degeneration were clearly observable in ewes euthanatized on the third day of toxicosis. Diagnosis of oxalate toxicosis was confirmed by histopathologic findings. Samples of Rumex spp contained 6.6 to 11.1% oxalic acid on a dry-weight basis, a concentration comparable with that in other oxalate-containing plants that have caused acute oxalate toxicosis.

    Complementary and alternative medicine (CAM) use among cancer patients is widely prevalent and often underreported. Advanced stage of disease is significantly associated with CAM use. The concurrent use of alternative medicines and chemotherapy drugs has the potential to lead to toxicities as well as altered therapeutic activity due to unknown interactions. We report a case of early breast cancer who presented to us with non-oliguric acute renal failure related concurrent use of Ayurvedic medicines and adjuvant anthracycline based.

    Acute tubular necrosis (ATN), especially from toxic injury is frequently accompanied by tubular casts and crystals. Myeloma casts, myoglobin, red blood cell and granular casts are well described. However, bile casts in tubules are rarely seen. We describe a case of Tribulus terrestris toxicity in a young healthy male, presenting with severe hyperbilirubinemia followed by acute renal failure and bile containing casts in the tubules. Tribulus terrestris is an herb often used by athletes as a nutritional supplement for performance enhancement. Although it is thought to be relatively safe, serious side effects have been reported before. Our aim is to increase awareness of the potential toxicities of performance enhancing herbal medications. These are often sold over-the-counter and therefore casually used, especially by young healthy individuals. Beneficial effects are controversial. Under-reporting by patients and infrequent documentation by health-care providers can delay diagnosis. We elaborately describe the kidney biopsy findings in Tribulus terrestris toxicity, and also provide a concise overview of the spectrum of tubular casts and their staining patterns, found in various kidney diseases.

Methods: In 12 healthy subjects (mean age 32 ± 4 years, color Doppler imaging, short-wavelength automated perimetry, and frequency doubling perimetry was performed before and 60 minutes after oral intake of 80 mL of 40 vol% ethanol. Mean and pattern standard deviations for short-wavelength automated and frequency doubling perimetry were assessed. End diastolic velocity (EDV and peak systolic velocity (PSV were measured in the central retinal and ophthalmic arteries using color Doppler imaging. Systemic blood pressure, heart rate, intraocular pressure, and blood alcohol concentration were determined. Results: Mean PSV and EDV in the central retinal artery showed a significant increase after alcohol intake (P = 0.03 and P = 0.02, respectively. Similarly, we found a significant acceleration of blood flow velocity in the ophthalmic artery (P = 0.02 for PSV; P = 0.04 for EDV. Mean intraocular pressure decreased by 1.0 mmHg after alcohol ingestion (P = 0.01. Retinal sensitivity in short-wavelength automated perimetry did not alter, whereas in frequency doubling perimetry, the mean deviation decreased significantly. Systolic and diastolic blood pressure did not change significantly. Mean blood alcohol concentration was 0.38 ± 0.16 g/L. Conclusion: Although ethanol is known to cause peripheral vasodilation, our subjects had no significant drop in systemic blood pressure. However, a significant increase of blood flow velocity was seen in the retrobulbar vessels. Regarding visual function

    Caffeine is the most widely used drug in the world, commonly ingested in coffee, tea, soda, and energy drinks. Its ability to enhance muscular work has been apparent since the early 1900s. Caffeine typically increases endurance performance; however, efficacy of caffeine ingestion for short-term high-intensity exercise is equivocal, which may be explained by discrepancies in exercise protocols, dosing, and subjects' training status and habitual caffeine intake found across studies. The primary aim of this review is to critically examine studies that have tested caffeine's ability to augment performance during exercise dependent on nonoxidative metabolism such as sprinting, team sports, and resistance training. A review of the literature revealed 29 studies that measured alterations in short-term performance after caffeine ingestion. Each study was critically analyzed using the Physiotherapy Evidence Database (PEDro) scale. The mean PEDro score was 7.76 +/- 0.87. Eleven of 17 studies revealed significant improvements in team sports exercise and power-based sports with caffeine ingestion, yet these effects were more common in elite athletes who do not regularly ingest caffeine. Six of 11 studies revealed significant benefits of caffeine for resistance training. Some studies show decreased performance with caffeine ingestion when repeated bouts are completed. The exact mechanism explaining the ergogenic effect of caffeine for short-term exercise is unknown.

    Dehydration has been shown to hinder performance of sustained exercise in the heat. Consuming fluids before exercise can result in hyperhydration, delay the onset of dehydration during exercise and improve exercise performance. However, humans normally drink only in response to thirst, which does not result in hyperhydration. Thirst and voluntary fluid consumption have been shown to increase following oral ingestion or infusion of sodium into the bloodstream. We measured the effects of acute sodium ingestion on voluntary water consumption and retention during a 2-hr hydration period before exercise. Subjects then performed a 60-min submaximal dehydration ride (DR) followed immediately by a 200 kJ performance time trial (PTT) in a warm (30 °C) environment. Water consumption and retention during the hydration period was greater following sodium ingestion (1380 ± 580 mL consumed, 821 ± 367 ml retained) compared with placebo (815 ± 483 ml consumed, 244 ± 402 mL retained) and no treatment (782 ± 454 ml consumed, 148 ± 289 mL retained). Dehydration levels following the DR were significantly less after sodium ingestion (0.7 ± 0.6%) compared with placebo (1.3 ± 0.7%) and no treatment (1.6 ± 0.4%). Time to complete the PTT was significantly less following sodium consumption (773 ± 158 s) compared with placebo (851 ± 156 s) and no treatment (872 ± 190 s). These results suggest that voluntary hyperhydration can be induced by acute consumption of sodium and has a favorable effect on hydration status and performance during subsequent exercise in the heat.

    A review of records from the AnTox database of the American Society for the Prevention of Cruelty to Animals Animal Poison Control Center identified 43 dogs that developed increased blood urea nitrogen concentration, serum creatinine concentration, or both as well as clinical signs after ingesting grapes, raisins, or both. Clinical findings, laboratory findings, histopathological findings, treatments performed, and outcome were evaluated. All dogs vomited, and lethargy, anorexia, and diarrhea were other common clinical signs. Decreased urine output, ataxia, or weakness were associated with a negative outcome. High calcium x phosphorus product (Ca x P), hyperphosphatemia, and hypercalcemia were present in 95%, 90%, and 62% of the dogs in which these variables were evaluated. Extremely high initial total calcium concentration, peak total calcium concentration, initial Ca x P, and peak Ca x P were negative prognostic indicators. Proximal renal tubular necrosis was the most consistent finding in dogs for which histopathology was evaluated. Fifty-three percent of the 43 dogs survived, with 15 of these 23 having a complete resolution of clinical signs and azotemia. Although the mechanism of renal injury from grapes and raisins remains unclear, the findings of this study contribute to an understanding of the clinical course of acute renal failure that can occur after ingestion of grapes or raisins in dogs.

    Full Text Available An abnormal glycemic profile, including postprandial glycemia and acute glucose spikes, precedes the onset of overt diabetes in obese subjects. Previous studies have shown the beneficial effects of chronic native banana starch (NBS supplementation. In this study, we examined the effects of acute ingestion of NBS on glycemic profiles by means of continuous glucose monitoring in obese and lean subjects. In a crossover study, obese and lean subjects consumed beverages containing either 38.3 g of NBS or 38.3 g of digestible corn starch (DCS twice daily during 4 days. On day 5, a 3-h meal tolerance test (MTT was performed to evaluate glucose and insulin responses. After 1 week of washout period, treatments were inverted. NBS supplementation reduced the 48-h glycemia AUC in lean, obese, and in the combined group of lean and obese subjects in comparison with DCS. Postprandial glucose and insulin responses at MTT were reduced after NBS in comparison with DCS in all groups. However, no changes were observed in glycemic variability (GV indexes between groups. In conclusion, acute NBS supplementation improved postprandial glucose and insulin responses in obese and lean subjects during 48 h of everyday life and at MTT. Further research to elucidate the mechanism behind these changes is required.

    Human aging is associated with reduced skeletal muscle perfusion during exercise, which may be a result of impaired endothelium-dependent dilation and/or attenuated ability to blunt sympathetically mediated vasoconstriction. Intra-arterial infusion of ascorbic acid (AA) increases nitric oxide-mediated vasodilation and forearm blood flow (FBF) during handgrip exercise in older adults, yet it remains unknown whether an acute oral dose can similarly improve FBF or enhance the ability to blunt sympathetic vasoconstriction during exercise. We hypothesized that 1) acute oral AA would improve FBF (Doppler ultrasound) and oxygen consumption (V̇o2) via local vasodilation during graded rhythmic handgrip exercise in older adults (protocol 1), and 2) AA ingestion would not enhance sympatholysis in older adults during handgrip exercise (protocol 2). In protocol 1 (n = 8; 65 ± 3 yr), AA did not influence FBF or V̇o2 during rest or 5% maximal voluntary contraction (MVC) exercise, but increased FBF (199 ± 13 vs. 248 ± 16 ml/min and 343 ± 24 vs. 403 ± 33 ml/min; P vasodilation.

    The purpose of this study was to examine the effects of acute ingestion of a pre-workout dietary supplement (PWS) with and without p-synephrine (S) on perceptions of readiness to perform, cognitive function, exercise performance, and markers of safety. In a randomized, double-blind, and counterbalanced manner; 25 healthy and recreationally active male and female participants ingested a flavored maltodextrin placebo (PLA), a PWS containing beta-alanine (3 g), creatine nitrate as a salt (2 g), arginine alpha-ketoglutarate (2 g), N-Acetyl-L-Tyrosine (300 mg), caffeine (284 mg), Mucuna pruiriens extract standardized for 15% L-Dopa (15 mg), Vitamin C as Ascorbic Acid (500 mg), niacin (60 mg), folate as folic acid (50 mg), and Vitamin B12 as Methylcobalamin (70 mg) with 2 g of maltodextrin and flavoring; or, the PWS with Citrus aurantium (PWS + S) extract standardized for 30% p-synephrine (20 mg). Participants had heart rate (HR), blood pressure, resting energy expenditure (REE), 12-lead electrocardiograms (ECG), perceptions about readiness to perform, cognitive function (Stroop Color-Word test), bench and leg press performance (2 sets of 10 repetitions at 70% of 1RM and 1 set to failure), and Wingate anaerobic capacity (WAC) sprint performance determined as well as donated blood samples prior to and/or following exercise/supplementation. Data were analyzed by MANOVA with repeated measures as well as mean changes from baseline with 95% confidence intervals (CI). No clinically significant differences were observed among treatments in HR, blood pressure, ECG, or general clinical blood panels. There was evidence that PWS and PWS + S ingestion promoted greater changes in REE responses. Participants reported higher perception of optimism about performance and vigor and energy with PWS and PWS + S ingestion and there was evidence that PWS and PWS + S improved changes in cognitive function scores from baseline to a greater degree than PLA after 1 or

    Dietary nitrate, from beetroot, has been reported to lower blood pressure (BP) by the sequential reduction of nitrate to nitrite and further to NO in the circulation. However, the impact of beetroot on microvascular vasodilation and arterial stiffness is unknown. In addition, beetroot is consumed by only 4.5% of the UK population, whereas bread is a staple component of the diet. Thus, we investigated the acute effects of beetroot bread (BB) on microvascular vasodilation, arterial stiffness, and BP in healthy participants. Twenty-three healthy men received 200 g bread containing 100 g beetroot (1.1 mmol nitrate) or 200 g control white bread (CB; 0 g beetroot, 0.01 mmol nitrate) in an acute, randomized, open-label, controlled crossover trial. The primary outcome was postprandial microvascular vasodilation measured by laser Doppler iontophoresis and the secondary outcomes were arterial stiffness measured by Pulse Wave Analysis and Velocity and ambulatory BP measured at regular intervals for a total period of 6 h. Plasma nitrate and nitrite were measured at regular intervals for a total period of 7 h. The incremental area under the curve (0-6 h after ingestion of bread) for endothelium-independent vasodilation was greater (P = 0.017) and lower for diastolic BP (DBP; P = 0.032) but not systolic (P = 0.99) BP after BB compared with CB. These effects occurred in conjunction with increases in plasma and urinary nitrate (P vasodilation and decreased DBP. Therefore, enriching bread with beetroot may be a suitable vehicle to increase intakes of cardioprotective beetroot in the diet and may provide new therapeutic perspectives in the management of hypertension.

Insulin area under the curve (AUC for sourdough and white was lower than 11-grain and sprouted-grain breads. GLP-1 response to sourdough was lower than all breads. In part 2, glucose and insulin AUC for sourdough was greater than 11-grain, sprouted-grain, and 12-grain breads. Sprouted-grain bread improved glycemia by lowering glucose response and increasing GLP-1 response. In overweight and obese men, the glycemic response to sprouted grain bread was reduced in both parts 1 and 2 while the other whole-grain test breads did not improve metabolic responses in the acute postprandial state.

    Full Text Available Abstract Background Studies show that obese individuals have prolonged elevations in postprandial lipemia and an exacerbated inflammatory response to high fat meals, which can increase risk for cardiovascular diseases. As epidemiological studies indicate an association between type of fat and circulating inflammatory markers, the purpose of this study was to investigate the acute effect of different fat sources on inflammation and oxidative stress in overweight and obese individuals. Methods Eleven overweight and obese subjects consumed three high fat milkshakes rich in monounsaturated fat (MFA, saturated fat (SFA, or long-chain omega 3 polyunsaturated fat (O3FA in random order. Blood samples collected at baseline, 1, 2, 4, and 6 hours postprandial were analyzed for markers of inflammation (soluble intercellular adhesion molecule-1 (ICAM-1, vascular cell adhesion molecule-1 (VCAM-1, tumor necrosis factor- α (TNF-α, and C-reactive protein (CRP, oxidative stress (8-epi-prostaglandin-F2α (8-epi and nuclear factor-κB (NF-κB, and metabolic factors (glucose, insulin, non-esterified free fatty acids, and triglycerides (TG. Results O3FA enhanced NF-kB activation compared to SFA, but did not increase any inflammatory factors measured. Conversely, SFA led to higher ICAM-1 levels than MFA (p = 0.051, while MFA increased TG more than SFA (p Conclusions While most of the inflammatory factors measured had modest or no change following the meal, ICAM-1 and NF-κB responded differently by meal type. These results are provocative and suggest that type of fat in meals may differentially influence postprandial inflammation and endothelial activation.

Within 30 min of ingestion, he became somnolent, confused, and agitated, with palpitation and vomiting. On arrival to the emergency department, a short run of supraventricular tachycardia was noted, which resolved spontaneously. Bedside urine immunoassay failed to detect recreational drugs. Laboratory blood tests showed mild hypokalemia. Exposure to AB-FUBINACA and ADB-FUBINACA was confirmed analytically, with serum concentrations of 5.6 ng/mL and 15.6 ng/mL, respectively, in the blood sample collected on presentation. The patient recovered uneventfully with supportive treatment and was discharged 22 h after admission. AB-FUBINACA and ADB-FUBINACA are orally bioavailable with rapid onset of toxicity after ingestion. In this case, supraventricular tachycardia was likely the result of exposure to AB-FUBINACA and ADB-FUBINACA. The serum concentrations of AB-FUBINACA and ADB-FUBINACA were higher than those previously reported in fatal cases. In the context of acute poisoning, the presence of unexplained tachyarrhythmias, confusion, and a negative recreational drug screen should prompt clinicians to consider synthetic cannabinoid toxicity as a differential diagnosis.

    Full Text Available Abstract Background Whey protein is a potential source of bioactive peptides. Based on findings from in vitro experiments indicating a novel whey derived peptide (NOP-47 increased endothelial nitric oxide synthesis, we tested its effects on vascular function in humans. Methods A randomized, placebo-controlled, crossover study design was used. Healthy men (n = 10 and women (n = 10 (25 ± 5 y, BMI = 24.3 ± 2.3 kg/m2 participated in two vascular testing days each preceded by 2 wk of supplementation with a single dose of 5 g/day of a novel whey-derived peptide (NOP-47 or placebo. There was a 2 wk washout period between trials. After 2 wk of supplementation, vascular function in the forearm and circulating oxidative stress and inflammatory related biomarkers were measured serially for 2 h after ingestion of 5 g of NOP-47 or placebo. Macrovascular and microvascular function were assessed using brachial artery flow mediated dilation (FMD and venous occlusion strain gauge plethysmography. Results Baseline peak FMD was not different for Placebo (7.7% and NOP-47 (7.8%. Placebo had no effect on FMD at 30, 60, and 90 min post-ingestion (7.5%, 7.2%, and 7.6%, respectively whereas NOP-47 significantly improved FMD responses at these respective postprandial time points compared to baseline (8.9%, 9.9%, and 9.0%; P P = 0.008 for time × trial interaction. Plasma myeloperoxidase was increased transiently by both NOP-47 and placebo, but there were no changes in markers inflammation. Plasma total nitrites/nitrates significantly decreased over the 2 hr post-ingestion period and were lower at 120 min after placebo (-25% compared to NOP-47 (-18%. Conclusion These findings indicate that supplementation with a novel whey-derived peptide in healthy individuals improves vascular function.

    To determine if age-associated vascular dysfunction in older adults with heart failure (HF) is due to insufficient synthesis of nitric oxide (NO), we performed two separate studies: 1) a kinetic study with a stable isotope tracer method to determine in vivo kinetics of NO metabolism, and 2) a vascular function study using a plethysmography method to determine reactive hyperemic forearm blood flow (RH-FBF) in older and young adults in the fasted state and in response to citrulline ingestion. In the fasted state, NO synthesis (per kg body wt) was ∼ 50% lower in older vs. young adults and was related to a decreased rate of appearance of the NO precursor arginine. Citrulline ingestion (3 g) stimulated de novo arginine synthesis in both older [6.88 ± 0.83 to 35.40 ± 4.90 μmol · kg body wt(-1) · h(-1)] and to a greater extent in young adults (12.02 ± 1.01 to 66.26 ± 4.79 μmol · kg body wt(-1) · h(-1)). NO synthesis rate increased correspondingly in older (0.17 ± 0.01 to 2.12 ± 0.36 μmol · kg body wt(-1) · h(-1)) and to a greater extent in young adults (0.36 ± 0.04 to 3.57 ± 0.47 μmol · kg body wt(-1) · h(-1)). Consistent with the kinetic data, RH-FBF in the fasted state was ∼ 40% reduced in older vs. young adults. However, citrulline ingestion (10 g) failed to increase RH-FBF in either older or young adults. In conclusion, citrulline ingestion improved impaired NO synthesis in older HF adults but not RH-FBF, suggesting that factors other than NO synthesis play a role in the impaired RH-FBF in older HF adults, and/or it may require a longer duration of supplementation to be effective in improving RH-FBF.

    A common belief is that alkali ingestion causes severe esophageal damage and limited gastric injury due to the buffering action of acid. Gastric injury has been observed in patients who ingested alkali. Gastric outlet obstruction (GOO) secondary to caustic ingestion occurs due to fibrosis after resolution of the acute injury and inflammation, most commonly 6 to 12 weeks after initial ingestion. The traditional treatment for GOO related to ingestion of corrosive agents is surgery. Experience w...

    Structural characteristics and baking conditions influence the metabolic responses to carbohydrate-containing foods. We hypothesized that consumption of whole wheat or sourdough breads would have a favourable effect on biomarkers of glucose homeostasis after first and second meals, compared with those for white bread. Ten overweight volunteers consumed 50 g available carbohydrate of each of the four breads (white, whole wheat, sourdough, whole wheat barley) followed 3 h later by a standard second meal. Blood was sampled for 3 h following bread ingestion and a further 2 h after the second meal for determination of glucose, insulin, paracetamol (indirect marker of gastric emptying), glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1). Glucose and GLP-1 responses to sourdough bread were lower (P breads. Glucose area under the curve (AUC) for sourdough bread was lower than those for whole wheat (P breads for the entire study. GIP AUC after sourdough bread ingestion was lower compared to white (P breads following the second meal. There were no significant differences in insulin and paracetamol concentrations among the test breads. Ultra-fine grind whole wheat breads did not result in postprandial responses that were lower than those of white bread, but sourdough bread resulted in lower glucose and GLP-1 responses compared to those of these whole wheat breads following both meals.

    The "J shape" curve linking the risk of poor bone health to alcohol intake is now well recognized from epidemiological studies. Ethanol and nonethanol components of alcoholic beverages could influence bone remodeling. However, in the absence of a solid underlying mechanism, the positive association between moderate alcoholic intake and BMD remains questionable because of confounding associated social factors. The objective of this work was to characterize the short-term effects of moderate alcohol consumption on circulating bone markers, especially those involved in bone resorption. Two sequential blood-sampling studies were undertaken in fasted healthy volunteers (age, 20-47 yr) over a 6-h period using beer of different alcohol levels (2% ethanol; p 6 h). The early effect on bone resorption is well described after the intake of energy, mediated by glucagon-like peptide-2, but the late effect of moderate alcohol ingestion is novel, seems to be ethanol specific, and is mediated in a non-calcitonin- and a non-PTH-dependent fashion, thus providing a mechanism for the positive association between moderate alcohol ingestion and BMD.

    Small plastic detritus, termed "microplastics", are a widespread and ubiquitous contaminant of marine ecosystems across the globe. Ingestion of microplastics by marine biota, including mussels, worms, fish, and seabirds, has been widely reported, but despite their vital ecological role in marine food-webs, the impact of microplastics on zooplankton remains under-researched. Here, we show that microplastics are ingested by, and may impact upon, zooplankton. We used bioimaging techniques to document ingestion, egestion, and adherence of microplastics in a range of zooplankton common to the northeast Atlantic, and employed feeding rate studies to determine the impact of plastic detritus on algal ingestion rates in copepods. Using fluorescence and coherent anti-Stokes Raman scattering (CARS) microscopy we identified that thirteen zooplankton taxa had the capacity to ingest 1.7-30.6 μm polystyrene beads, with uptake varying by taxa, life-stage and bead-size. Post-ingestion, copepods egested faecal pellets laden with microplastics. We further observed microplastics adhered to the external carapace and appendages of exposed zooplankton. Exposure of the copepod Centropages typicus to natural assemblages of algae with and without microplastics showed that 7.3 μm microplastics (>4000 mL(-1)) significantly decreased algal feeding. Our findings imply that marine microplastic debris can negatively impact upon zooplankton function and health.

    A 69-year-old woman presented with acute kidney failure of unknown cause that ultimately required dialysis. Kidney biopsy revealed the diagnosis of oxalate nephropathy. In retrospect, the patient had several risk factors for this entity, including excessive vitamin C intake, a remote history of Roux-en-Y gastric bypass for weight loss, and chronic kidney disease. This presentation of multiple risk factors for oxalate nephropathy is especially relevant to patients and physicians considering the increase in the United States of vitamin C supplementation use and gastric bypass surgery. It is important for physicians to maintain an awareness of this diagnosis and its risk factors.

    The high intake of dietary sodium (Na(+)) has been associated with obesity and insulin resistance, sparking the hypothesis that the consumption of salty foods affects food intake (FI) and postprandial blood glucose (BG) response. Therefore, we conducted 2 randomized repeated-measures experiments to examine the acute effects of the Na(+) content of solid food and beverage on FI, water intake (WI), subjective appetite, thirst, and BG. FI and WI were measured at ad libitum pizza test meals; appetite, thirst, and BG were measured at baseline and at regular intervals before and after meals. In the first experiment, 16 males (mean body mass index (BMI), 22.2 kg·m(-2)) consumed a low-Na(+) (71 mg) bean preload (300 kcal) with or without 740 mg or 1480 mg of added Na(+) 120 min prior to the pizza meal. Participants ate 116 kcal more at the test meal after consuming beans with 740 mg of added Na(+) than after beans with 1480 mg of added Na(+). In the second experiment, 19 males (mean BMI, 23.2 kg·m(-2)) consumed a low-Na(+) (62 mg) tomato beverage (73 kcal) with or without 500, 1000, 1500, or 2000 mg of added Na(+) 30 min prior to a pizza meal. The beverage with 2000 mg of added Na(+) led to higher WI during the pizza meal than the beverage with 500 mg of added Na(+). However, compared with the control conditions (no added Na(+)), added Na(+) treatments had no effect on dependent measures in either experiment. In conclusion, the acute intake of Na(+), in a solid or liquid form, did not affect short-term subjective ratings of appetite or thirst, ad libitum FI or WI, or BG in healthy young men.

    Full Text Available This is a case report of foreign body ingestion in a suicide attempt resulting in gastric perforation and phlegmon formation during a subsequent 6 month period that eventually required surgical intervention. The patient had a prolonged course because she did not report a history of foreign body ingestion and the initial evaluating physicians had no suspicion about possible foreign body ingestion and may have missed important findings on physical examination. Gastric perforation by a foreign object  may have a slow course rather than presenting acute abdomen. The realization of a proper physical examination in the emergency department is key to an accurate diagnosis.

    Foreign body ingestion is frequent in children and generally associated with little morbidity. However, some foreign bodies are innocent when ingested as a single object, but may have harmful effect if numerous. We report a 9-year-old girl who swallowed 5 magnets, causing acute intestinal obstruction. At laparotomy, 2 magnets were found in the cecum and 3 in the transverse colon, attracting each other and clasping a segment of ileum in between, causing a complete obstruction of the small intestine. If numerous magnets are ingested, particular concern is advised, and if signs of intestinal distress develop, prompt laparotomy to prevent serious gastrointestinal complications should be performed.

    Fifteen consecutive children with ingested safety pins were evaluated retrospectively. Eight patients were males and seven were girls. The mean age of the patients was 5.4 years ranging from 7 months to 16 years. Two of 15 patients were mentally retarded Seven safety pins ingestion were noted by parents, three older children applied with safety pin swallowing. Three infants referred with hypersalivation and swallowing difficulty. One of two mentally retarded patients had recurrent aspiration pneumonia, the other had neck abscess. These patients' lesions were detected incidentally by thoracic X-ray. Nine safety pins were at the level of the cricopharyngeus, one at the level of the aortic arch and five at the esophagogastric junction. A right esophagoscopy was used for extraction of safety pins under general anesthesia and endotracheal intubation were used. Before esophagoscopy control plain X-ray was obtained for location of safety pin. Nine safety pins were extracted by esophagoscopy. Three safety pins spontaneously and three during anesthesia induction passed through the esophagus falling down the stomach. Five of these six safety pins were spontaneously extracted without complication. However one open safety pin lodged at the duodenum and laparotomy was required. In this article, etiology and management of safety pin ingestion in children are discussed.

    Objective To identify the computed tomography findings suggestive of intestinal perforation by an ingested foreign body. Materials and Methods This was a retrospective study of four cases of surgically proven intestinal perforation by a foreign body, comparing the computed tomography findings with those described in the literature. Results None of the patients reported having ingested a foreign body, all were over 60 years of age, three of the four patients used a dental prosthesis, and all of the foreign bodies were elongated and sharp. In all four patients, there were findings indicative of acute abdomen. None of the foreign bodies were identified on conventional X-rays. The computed tomography findings suggestive of perforation were thickening of the intestinal walls (in all four cases), increased density of mesenteric fat (in all four cases), identification of the foreign body passing through the intestinal wall (in three cases), and gas in the peritoneal cavity (in one case). Conclusion In cases of foreign body ingestion, intestinal perforation is more common when the foreign body is elongated and sharp. Although patients typically do not report having ingested such foreign bodies, the scenario should be suspected in elderly individuals who use dental prostheses. A computed tomography scan can detect foreign bodies, locate perforations, and guide treatment. The findings that suggest perforation are thickening of the intestinal walls, increased mesenteric fat density, and, less frequently, gas in the peritoneal cavity, often restricted to the point of perforation.

    The mechanisms by which natural rewards such as sugar affect synaptic transmission and behavior are largely unexplored. Here, we investigate regulation of nucleus accumbens synapses by sucrose intake. Previous studies have shown that AMPA receptor (AMPAR) trafficking is a major mechanism for regulating synaptic strength, and that in vitro, trafficking of AMPARs containing the GluA1 subunit takes place by a two-step mechanism involving extrasynaptic and then synaptic receptor transport. We report that in rat, repeated daily ingestion of a 25% sucrose solution transiently elevated spontaneous locomotion and potentiated accumbens core synapses through incorporation of Ca(2+)-permeable AMPA receptors (CPARs), which are GluA1-containing, GluA2-lacking AMPARs. Electrophysiological, biochemical, and quantitative electron microscopy studies revealed that sucrose training (7 d) induced a stable (>24 h) intraspinous GluA1 population, and that in these rats a single sucrose stimulus rapidly (5 min) but transiently (<24 h) elevated GluA1 at extrasynaptic sites. CPARs and dopamine D1 receptors were required in vivo for elevated locomotion after sucrose ingestion. Significantly, a 7 d protocol of daily ingestion of a 3% solution of saccharin, a noncaloric sweetener, induced synaptic GluA1 similarly to 25% sucrose ingestion. These findings identify multistep GluA1 trafficking, previously described in vitro, as a mechanism for acute regulation of synaptic transmission in vivo by a natural orosensory reward. Trafficking is stimulated by a chemosensory pathway that is not dependent on the caloric value of sucrose.

    Tarango Md, Stacy M; Liu Md, Deborah R

    2016-04-01

    Pediatric ingestions present a common challenge for emergency clinicians. Each year, more than 50,000 children aged less than 5 years present to emergency departments with concern for unintentional medication exposure, and nearly half of all calls to poison centers are for children aged less than 6 years. Ingestion of magnetic objects and button batteries has also become an increasing source of morbidity and mortality. Although fatal pediatric ingestions are rare, the prescription medications most responsible for injury and fatality in children include opioids, sedative/hypnotics, and cardiovascular drugs. Evidence regarding the evaluation and management of common pediatric ingestions is comprised largely of case reports and retrospective studies. This issue provides a review of these studies as well as consensus guidelines addressing the initial resuscitation, diagnosis, and treatment of common pediatric ingestions. Also discussed are current recommendations for decontamination, administration of antidotes for specific toxins, and management of ingested foreign bodies.

    Raw or dried gallbladders of cyprinid fish have long been ingested as a traditional medicine in the Asian countries, particularly in China, for ameliorating visual acuity, rheumatism, and general health; however, sporadic poisoning incidences have occurred after their ingestion. The poisoning causes complex symptoms in patients, including acute renal failure, liver dysfunction, paralysis, and convulsions of limbs. The causative substance for the poisoning was isolated, and its basic properties were examined. The purified toxin revealed a minimum lethal dose of 2.6 mg/20 g in mouse, when injected intraperitoneally. The main symptoms were paralysis and convulsions of the hind legs, along with other neurological signs. Liver biopsy of the euthanized mice clearly exhibited hepatocytes necrosis and infiltration of neutrophils and lymphocytes, suggesting the acute dysfunction of the liver. Blood tests disclosed the characteristics of acute renal failure and liver injury. Infrared (IR) spectrometry, fast atom bombardment (FAB) mass spectrometry, and 1H- and 13C-nuclear magnetic resonance (NMR) analysis indicated, a molecular formula of C27H48O8S, containing a sulfate ester group for the toxin. Thus, we concluded that the structure of carp toxin to be 5α-cyprinol sulfate (5α-cholestane-3α, 7α, 12α, 26, 27-pentol 26-sulfate). This indicated that carp toxin is a nephro- and hepato- toxin, which could be the responsible toxin for carp bile poisoning in humans.

    Full Text Available Cocaine is considered a leading cause of drug-related deaths. This is usually sudden, unwitnessed, and without prodromal features. It has been reported that in-hospital mortality is close to 2%. Cocaine has powerful central nervous system effects1 and acute cocaine overdose has been associated with hyperthermia, agitation, paranoid ideation, status epilepticus, ventricular fibrillation, ventricular tachycardia, and myocardial infarction (MI. The mechanisms of cocaine-related death remain poorly understood. We report a patient who survived massive cocaine ingestion with psychomotor agitation and generalized seizures followed by asystolic cardiac arrest and transient Brugada pattern on electrocardiogram (ECG.

    Kounis syndrome (KS) is a complex of cardiovascular symptoms and signs following either allergy or hypersensitivity and anaphylactic or anaphylactoid insults. We report the case of 57-year-old man, with hypertension and history of allergy, referred for facial rash and palpitations appeared after consumption of canned tuna fish. Suddenly, the patient collapsed: electrocardiogram showed ST-elevation in inferior leads. The patient was transferred from the spoke emergency room for coronary angio, which did not show any sign of coronary atherosclerosis. A transient coronary spasm was therefore hypothesized and the final diagnosis was KS. To the best of our knowledge, this is one of the first cases of KS following the ingestion of tuna fish. KS secondary to food allergy has also been reported, and shellfish ingestion has been considered as one of the most active KS inducer foods. Canned tuna fish too is well known as an allergy inducer. Tuna fish allergy should be considered, however, within the context of scombroid food poisoning, also called histamine fish poisoning. Fish with high levels of free histidine, the enzyme substrate converted to histamine by bacterial histidine decarboxylase, are those most often implicated in scombroid poisoning. Inflammatory mediators such as histamine constitute the pathophysiologic basis of Kounis hypersensitivity-associated acute coronary syndrome. Patients with coronary risk factors, allergic reaction after food ingestion, and suspected scombroid poisoning should be therefore carefully monitored for a prompt diagnosis of possible coronary complications.

  14. Salt ingestion caves.

    2006-01-01

    Full Text Available Large vertebrate herbivores, when they find a salt-bearing layer of rock, say in a cliff face, can produce sizable voids where, overgenerations, they have removed and consumed salty rock. The cavities formed by this natural animal process constitute a uniqueclass of caves that can be called salt ingestion caves. Several examples of such caves are described in various publications. Anexample in Mississippi U.S.A., Rock House Cave, was visited by the authors in 2000. It seems to have been formed by deer orbison. Perhaps the most spectacular example is Kitum Cave in Kenya. This cave has been excavated to a length over 100 metersby elephants. An ancient example is La Cueva del Milodon in Chile, which is reported to have been excavated by the now extinctmilodon, a giant ground sloth. Still other possible examples can be cited. This class of caves deserves a careful definition. First, thecavity in rock should meet the size and other conventions of the locally accepted definition of a cave. Of course this requirement differsin detail from country to country, particularly in the matter of size. The intent is to respect the local conventions. The characteristicthat human entry is possible is judged to be a crucial property of any recognized cave definition. Second, the cavity should besignificantly the result of vertebrate animal consumption of salt-bearing rock. The defining process is that rock removed to form thecave is carried away in the digestive track of an animal. While sodium salts are expected to be the norm, other salts for which thereis animal hunger are acceptable. Also some other speleogenesis process, such as solution, should not be excluded as long as it issecondary in formation of a cave in question.

    Full Text Available Treatment strategies for acute toxicity following massive ingestion of warfarin are not well described in the literature. Warfarin is the primary oral anticoagulation agent used in the treatment of thromboembolic disease, and patients with acute toxicity are at risk for life-threatening hemorrhages. Treatment options include phytonadione (vitamin K1, fresh frozen plasma (FFP, and prothrombin complex concentrates (PCCs used alone or in combination. FFP and PCC can be associated with volume complications, undesirable thromboembolic events, and increased costs. We describe the case of a 63-year-old female with acute warfarin toxicity following a massive ingestion of warfarin (420 mg–450 mg in an attempt to commit suicide. Upon arrival to the emergency department, serial INR checks were initiated to help guide dosing strategy and later adjusted based on INR response to treatment using only phytonadione.

    Ricci, Serafino; Massoni, Francesco; Schiffino, Luigi; Pelosi, Marcello; Salesi, Marialucia

    2014-03-01

    The ingestion of foreign bodies is one of the most important and difficult emergencies for a physician to diagnose. Accidental ingestion is more common in children, in patients with dental implants, in individuals with mental disability and in drug users. Voluntary ingestion is found in patients who are psychologically unstable, in prisoners or those who attempt suicide. Foreign bodies may be divided into food as fish bones, chicken bones, food bolus, meat, etc. or real foreign bodies such as orthodontic implants, needles, pins, glass, coins, etc. The authors present a case of management, from the medicolegal point of view, of a female patient age 80, who complained, for some weeks of modest pain in the left iliac fossa, and afterwards the endoscopy showed a toothpick into the wall of the sigmoid colon. Assessed of the clinical status of the patient presented severe cardiac comorbidities so that before processing the patient to a second resolutive endoscopy, it was necessary to obtain the hemodynamic stability. However the management of cases of accidental ingestion of foreign bodies is particularly difficult. Medical errors can arise from the very first contact with the patient resulting in delays in appropriate treatment. The doctor to avoid compromising its position on medical liability, must use all the knowledge and diligence known by the art and science of medicine.

    In contrast to the ingestion of coin batteries, the ingestion of cylindrical batteries is an uncommon medical presentation. Owing to their larger size, cylindrical battery ingestion can lead to serious complications including intestinal haemorrhage, bowel obstruction, bowel perforation, peritonitis and even death. We discuss the case of a 17-year-old girl who presented after swallowing three cylindrical batteries. Her medical history included depression and previous battery ingestion that required surgical removal. During this presentation however, these ingested batteries were removed endoscopically at oesophagogastroduodenoscopy and ileocolonoscopy. The patient was subsequently discharged without complication. This paper discusses the complications and management of cylindrical battery ingestion. 2017 BMJ Publishing Group Ltd.

  3. Uncertainty analysis of doses from ingestion of plutonium and americium.

    Puncher, M; Harrison, J D

    2012-02-01

    Uncertainty analyses have been performed on the biokinetic model for americium currently used by the International Commission on Radiological Protection (ICRP), and the model for plutonium recently derived by Leggett, considering acute intakes by ingestion by adult members of the public. The analyses calculated distributions of doses per unit intake. Those parameters having the greatest impact on prospective doses were identified by sensitivity analysis; the most important were the fraction absorbed from the alimentary tract, f(1), and rates of uptake from blood to bone surfaces. Probability distributions were selected based on the observed distribution of plutonium and americium in human subjects where possible; the distributions for f(1) reflected uncertainty on the average value of this parameter for non-specified plutonium and americium compounds ingested by adult members of the public. The calculated distributions of effective doses for ingested (239)Pu and (241)Am were well described by log-normal distributions, with doses varying by around a factor of 3 above and below the central values; the distributions contain the current ICRP Publication 67 dose coefficients for ingestion of (239)Pu and (241)Am by adult members of the public. Uncertainty on f(1) values had the greatest impact on doses, particularly effective dose. It is concluded that: (1) more precise data on f(1) values would have a greater effect in reducing uncertainties on doses from ingested (239)Pu and (241)Am, than reducing uncertainty on other model parameter values and (2) the results support the dose coefficients (Sv Bq(-1) intake) derived by ICRP for ingestion of (239)Pu and (241)Am by adult members of the public.

    Glutamine (GLN) attenuates acute lung injury (ALI) but its effect on alveolar macrophages is unknown. We hypothesized that GLN pretreatment would induce the anti-inflammatory CD163/heme oxygenase (HO)-1/p38-MAPK dephosphorylation pathway in alveolar macrophages and reduce ALI in rats insufflated with interleukin-1 (IL-1) and lipopolysaccharide (LPS). Male Sprague-Dawley rats were randomized to the following groups: GLN-IL-1/LPS-, GLN+IL-1/LPS-, GLN-IL-1/LPS+, and GLN+IL-1/LPS+. GLN pretreatment was given via gavage (1 g/kg L-alanyl-L-glutamine) daily for 2 days. ALI was subsequently induced by insufflating 50 ng IL-1 followed by 5mg/kg E.coli LPS. After 24h, bronchoalveolar lavage (BAL) protein, lactate dehydrogenase (LDH) and neutrophil concentrations were analyzed. BAL alveolar macrophage CD163+ expression, HO-1 and p38-MAPK concentrations were measured, as well as alveolar macrophage tumor necrosis factor (TNF)-α and interleukin (IL)-10 concentrations. Histology and immunofluorescence studies were also performed. Following IL-1/LPS insufflation, GLN pretreated rats had significantly decreased BAL protein and LDH concentrations, but not BAL neutrophil counts, compared to non-GLN pretreated rats. The number of alveolar macrophages and the number of CD163+ macrophages were significantly increased in GLN pretreated IL-1/LPS-insufflated rats compared to non-GLN pretreated, IL-1/LPS-insufflated rats. GLN pretreatment before IL-1/LPS also significantly increased HO-1 concentrations and dephosphorylated p38-MAPK levels but not cytokine levels in alveolar macrophages. Immunofluorescence localized CD163 and HO-1 in alveolar macrophages. Short-term GLN pretreatment activates the anti-inflammatory CD163/HO-1/p38-MAPK dephosphorylation pathway of alveolar macrophages and decreases capillary damage but not neutrophil recruitment in IL-1/LPS-insufflated rats.

    As the demand for small electronics continues to grow so does the risk of oesophageal ingestion of button batteries. These small but powerful sources of energy are ubiquitous in every household and when swallowed, especially in small children, have been shown to create significant injury in a short amount of time leading to long-term morbidity and possible death. This review highlights the latest findings regarding epidemiology, pathophysiology, diagnosis and management of ingested button batteries. Updated epidemiology from the National Capital Poison Center, new bench research looking at injury patterns and possible mitigation strategies, updated ideas on management algorithms including the use of a trauma protocol, close-look second endoscopy and management of button batteries in the lower gastrointestinal tract are reviewed in this paper. Despite advances in the understanding of injury mechanics and innovations leading to early diagnosis and improved management of button battery ingestion, parental and provider education remain the most important tools to keep children well tolerated from the sequelae of these potentially fatal events. Collaboration between healthcare experts, public health and industry is essential to find a safe answer to this ongoing threat.

  9. Sudden death due to forced ingestion of vinegar.

    Shields, Lisa B E; Rolf, Cristin M; Hunsaker, John C

    2016-09-01

    Vinegar is a clear colorless liquid that commercially consists of 5% acetic acid. It has numerous benefits in everyday use, including culinary, medical, and cleaning. The ingestion of concentrated acetic acid is strongly discouraged and may have detrimental consequences, such as acute pancreatitis, disseminated intravascular coagulopathy, gastric and hepatic complications, upper airway obstruction, or death. We report the first case in the literature of a 5-year-old boy who experienced a sudden death due to ingestion of distilled white vinegar. The manner was homicide. There was evidence of nonfatal blunt force impacts of the head, trunk, and extremities. A pungent aromatic odor of the viscera, gastric/small bowel contents, and cranial cavity was noted at autopsy. A dusky gray discoloration of the gastric mucosa, small bowel, and pancreas was observed. Forensic pathologists should consider ingestion of vinegar when confronted with a compelling history as well as an aromatic odor suggesting vinegar and dusky gray discoloration of the gastric mucosa and small bowel. While vinegar is a common household item and has several advantages, it may prove fatal if ingested in large quantities.

    The ingestion of large amounts of boric acid, a component of household insecticides, is a rare occurrence, characterized by a diffuse desquamative skin eruption, neutropenia, thrombocytopenia, delirium, acute renal failure and prolonged ileus. A 56-year-old male with a history of multiple previous suicide attempts was witnessed ingesting household roach killer and 4 days later presented to the hospital with lethargy, stiffness and a diffuse erythematous and desquamative eruption with bullous formation. He subsequently developed erythema of both palms as well as alopecia totalis. Histopathology from a right arm shave biopsy revealed a mostly intact epidermis with subtle vacuolar alteration of the basal layer, scattered intraepidermal apoptotic keratinocytes, parakeratosis with alternating layers of orthokeratosis and considerable superficial exfoliation; accompanying dermal changes included vasodilatation and mild perivascular inflammation. This report describes the cutaneous and systemic complications in a rare case of boric acid ingestion. There is little published material on the symptoms and histopathology following boric acid ingestion, but knowledge of this entity is important, both to differentiate it from other causes of desquamative skin rashes and to allow the initiation of appropriate clinical care. © 2013 John Wiley & Sons A/S.

  12. Physiologic Conditions Affect Toxicity of Ingested Industrial Fluoride

    Full Text Available The effects of calcium ion and broad pH ranges on free fluoride ion aqueous concentrations were measured directly and computed theoretically. Solubility calculations indicate that blood fluoride concentrations that occur in lethal poisonings would decrease calcium below prevailing levels. Acute lethal poisoning and also many of the chronic effects of fluoride involve alterations in the chemical activity of calcium by the fluoride ion. Natural calcium fluoride with low solubility and toxicity from ingestion is distinct from fully soluble toxic industrial fluorides. The toxicity of fluoride is determined by environmental conditions and the positive cations present. At a pH typical of gastric juice, fluoride is largely protonated as hydrofluoric acid HF. Industrial fluoride ingested from treated water enters saliva at levels too low to affect dental caries. Blood levels during lifelong consumption can harm heart, bone, brain, and even developing teeth enamel. The widespread policy known as water fluoridation is discussed in light of these findings.

    Herein, we present a case of anaphylaxis in multiple family members after ingesting silkworms, an Asian delicacy. While food allergies, including anaphylaxis are unfortunately common, there are no previous reports of multiple family members suffering an anaphylactic reaction after eating silkworms. In addition, both family members required multiple doses of epinephrine and eventually an epinephrine infusion to improve their blood pressures. All interventions, including the epinephrine infusions, were started by emergency medical services (EMS) with on-line medical direction. Both the reaction and the required treatment are not extensively documented in the medical literature.

  15. Ingested and Aspirated Foreign Bodies.

    Green, S Sarah

    2015-10-01

    Esophageal and aspirated foreign bodies have important clinical significance, and both should be considered carefully when the history or physical examination findings raise sufficient suspicion. The published evidence regarding the diagnosis and management of foreign body ingestion or aspiration is weighted disproportionately with observational studies, case controls, expert opinion, and systematic reviews. Most of the publications would receive a categorization of C (observational studies including case-control and cohort design) and D (expert opinion, case reports, and clinical reasoning). One of the few prospective studies examining the diagnostic evaluation of foreign body aspiration in children could be considered level B evidence (randomized clinical trials, systematic reviews, or diagnostic studies with minor limitations). This study found that the medical history is the most important predictive part of the evaluation. There is evidence for considering bronchoscopy if there is significant history suggestive of foreign body aspiration, even in the setting of normal physical examination findings. (28). Most ingested foreign bodies spontaneously pass without incident. However, special attention should be paid to objects in the esophagus as well as to batteries and magnets. Based on a systematic review of the literature (level B evidence) and the potential for rapid and life-threatening damage, batteries in the esophagus should be removed immediately. (10) Other objects, such as coins, may be observed for passage in an asymptomatic patient. In addition, given the high risk of significant complications, ingestion of high-powered magnets should be quickly and carefully evaluated. Although single magnets are likely to pass without complication, multiple magnets or magnets ingested with other metal objects can cause significant damage and should be removed if there is any concern for mural entrapment, bowel perforation, or failure to progress.

    35 year old intoxicated male ingested an unusual, large foreign object (cell phone). To report the ingestion of an unusual large foreign object with hypopharyngeal impaction, complications, and treatment. Foreign body ingestion in the adult population is more prevalent in those who engage in drug or alcohol abuse. Impaction and perforation of the upper aerodigestive tract can lead to significant and potentially fatal complications including parapharyngeal/retropharyngeal abscess, mediastinitis, and aortoesophageal fistula. The treatment of foreign object ingestion is dependent on the type of foreign object ingested, its location, and potential for perforation. Endoscopic removal under general anesthesia is the treatment method recommended for foreign bodies impacted at the cricopharyngeus or esophagus. We report the only case of the accidental ingestion of an entire cell phone with casing. A plain film x-ray of the neck can be used in the assessment of the location of radiopaque foreign objects and in diagnosing potential complication.

    Laundry detergent pods (LDPs) have only recently become available in the United States, and there has been increasing concern regarding pediatric ingestions of them. We describe a 15-month-old female infant who ingested an LDP and had a depressed level of consciousness, metabolic acidosis, pulmonary toxicity, and swallowing difficulties. It is currently unclear what the exact etiologic agent(s) is responsible for the toxicity associated with LDPs. The case demonstrates the potential for significant toxicity following the ingestion of an LDP. Clearly, measures should be taken to avoid ingestions of these products.

    We describe a comprehensive algorithm for the management of ingested rare-earth magnets in children. These newer and smaller neodymium magnets sold as adult toys are much stronger than the traditional magnets, and can attract each other with formidable forces. If >1 magnet is swallowed at the same time, or a magnet is co-ingested with another metallic object, the loops of intestine can be squeezed between them resulting in bowel damage including perforations. An algorithm that uses the number of magnets ingested, location of magnets, and the timing of ingestion before intervention helps to delineate the roles of the pediatric gastroenterologists and surgeons in the management of these cases.

    Button battery lodged in the esophagus carries a high risk of morbidity and mortality. The purpose of this study was to present cases of patients with esophageal button battery ingestion treated at our clinic and to emphasize the importance of early diagnosis and treatment. Records of patients admitted to our hospital for foreign body ingestion between January 2010 and May 2015 were retrospectively reviewed. Cases with button battery lodged in the esophagus were included in the study. Patient data regarding age, sex, length of time after ingestion until admission, presenting clinical symptoms, type and localization of the battery, management, and prognosis were analyzed. Among 1891 foreign body ingestions, 71 were localized in the esophagus, and 8 of those (11.2%) were cases of button battery ingestion. Mean age was 1.7 years. Admission was within 6 hours of ingestion in 5 cases, after 24 hours had elapsed in 2, and 1 month after ingestion in 1 case. All patients but 1 knew the history of ingestion. Prompt endoscopic removal was performed for all patients. Three patients developed esophageal stricture, which responded to dilatation. Early recognition and timely endoscopic removal is mandatory in esophageal button battery ingestion. It should be suspected in the differential diagnosis of patients with persistent respiratory and gastrointestinal symptoms.

    Heroin (diamorphine) is a highly addictive opiate with potential for misuse. A small number of reports have linked the commencement of heroin misuse to acute exotropia with diplopia and subsequent withdrawal to esotropia in individuals without previous symptoms.(1-5) We describe a young adult who sought strabismus surgery to correct a large-angle exotropia. Detailed patient history and orthoptic measurements at different times of the day revealed a fluctuating angle of divergence relating to the timing of opiate ingestion, rendering surgery inappropriate. We suggest that opiate misuse, which may not willingly be disclosed by patients, should be specifically asked about before acquired-strabismus surgery is undertaken in adults.

    A 9 month old girl at the emergency room appeared with an acute onset of restlessness, drooling and suspected foreign body ingestion. An X-Ray revealed an open safety pin in the child's upper aero-digestive tract. The source of the safety pin was a "Hamsah" good luck charm that was attached to her bed. Open safety pins in the aero-digestive tract are difficult to manage and great care must be taken during removal to prevent further injury. Parents should be counseled regarding the presence of safety pins in the child's surroundings in order to prevent such hazards.

    1988-01-01

    A thermal monitoring system for measuring body core temperatures was developed that contains an ingestible pill which is both commandable and rechargeable, and which uses magnetic induction for command and telemetry as well as for recharging. The pill electronics consist of a battery power source, a crystal-controlled oscillator that drives a small air coil, and a command detection circuit. The resulting 262-kHz magnetilc field can be easily detected from a distance of 1 m. The pill oscillator functions at voltages less than 1 V, supplied by a single Ni-Cd battery, which must be recharged after 72 h of continuous transmission. The pill can be recalibrated periodically to compensate for long-term drift.

    Lidocaine has a concentration-dependent effect on seizures. Concentrations above 15 μg/mL frequently result in seizures in laboratory animals and human. We report a case of central nervous system (CNS) lidocaine toxicity and recurrent seizure after erroneous ingestion of lidocaine solution. A 4-year-old boy presented to the Emergency Department of Imam Hospital of Sari in December 2013 due to tonic-clonic generalized seizures approximately 30 min ago. 3 h before seizure, his mother gave him 2 spoons (amount 20-25 cc) lidocaine hydrochloride 2% solution instead of pediatric gripe by mistake. Seizure with generalized tonic-clonic occurred 3 times in home. Neurological examination was essentially unremarkable except for the depressed level of consciousness. Personal and medical history was unremarkable. There was no evidence of intracranial ischemic or hemorrhagic lesions in computed tomography scan. There were no further seizures, the condition of the patient remained stable, and he was discharged 2 days after admission. The use of viscous lidocaine may result in cardiovascular and CNS toxicity, particularly in children. Conservative management is the best option for treatment of lidocaine induced seizure.

  7. Ingestion of Caustic Substances in Adults: A Review Article

    2013-02-01

    Full Text Available Background: Ingestion of caustic agents can cause serious damages of the upper gastrointestinal tract and in some cases this kind of poisoning may have fatal outcomes. Acute caustic intoxications are one of the main problems in the modern clinical toxicology since they mainly affect young people with psychic disorders, suicidal intent, and alcohol addiction. Text: In diagnostic evaluation of this kind of poisoning, different procedures are used. Today’s golden standard for determination of the grade and extent of the lesion is esophagogastroduodenoscopy (EGD performed in the first 12-24 hours following corrosive ingestion. In some patients, some late complications, such as esophageal stenosis and gastric stenosis, which are the most common, as well as carcinoma of the upper gastrointestinal tract, which is rarely seen, can be detected. Acute caustic poisonings are treated with specific kinds of protocols. According to them, first, an attempt is made to neutralize the poison. Combinations of antibiotics, anti-secretory drugs, and collagen synthesis inhibitors are used. As a support therapy, nutritional liquids can be utilized, and in the most unmanageable cases, esophageal dilatation, stent placement and surgery are used. Conclusion: In the future, caustic poisonings will remain a serious socio-medical issue, due to the difficult clinical presentation, expensive diagnostic protocol, extended hospitalization, and possible permanent disability.

    Exposure to chemicals from ingestion of contaminated soil may be an important pathway with potential health consequences for children. A key parameter used in assessing this exposure is the quantity of soil ingested, with estimates based on four short longitudinal mass-balance soil ingestion studies among children. The estimates use trace elements in the soil with low bioavailability that are minimally present in food. Soil ingestion corresponds to the excess trace element amounts excreted, after subtracting trace element amounts ingested from food and medications, expressed as an equivalent quantity of soil. The short duration of mass-balance studies, different concentrations of trace elements in food and soil, and potential for trace elements to be ingested from other nonsoil, nonfood sources contribute to variability and bias in the estimates. We develop a stochastic model for a soil ingestion estimator based on a trace element that accounts for critical features of the mass-balance equation. Using results from four mass-balance soil ingestion studies, we estimate the accuracy of soil ingestion estimators for different trace elements, and identify subjects where the difference between Al and Si estimates is larger (>3 RMSE) than expected. Such large differences occur in fewer than 12% of subjects in each of the four studies. We recommend the use of such criteria to flag and exclude subjects from soil ingestion analyses. © 2011 Society for Risk Analysis.

  14. Ice crystal ingestion by turbofans

    Science.gov (United States)

    Rios Pabon, Manuel A.

    This Thesis will present the problem of inflight icing in general and inflight icing caused by the ingestion of high altitude ice crystals produced by high energy mesoscale convective complexes in particular, and propose a new device to prevent it based on dielectric barrier discharge plasma. Inflight icing is known to be the cause of 583 air accidents and more than 800 deaths in more than a decade. The new ice crystal ingestion problem has caused more than 100 flights to lose engine power since the 1990's, and the NTSB identified it as one of the causes of the Air France flight 447 accident in 1-Jun2008. The mechanics of inflight icing not caused by ice crystals are well established. Aircraft surfaces exposed to supercooled liquid water droplets will accrete ice in direct proportion of the droplet catch and the freezing heat transfer process. The multiphase flow droplet catch is predicted by the simple sum of forces on each spherical droplet and a droplet trajectory calculation based on Lagrangian or Eulerian analysis. The most widely used freezing heat transfer model for inflight icing caused by supercooled droplets was established by Messinger. Several computer programs implement these analytical models to predict inflight icing, with LEWICE being based on Lagrangian analysis and FENSAP being based on Eulerian analysis as the best representatives among them. This Thesis presents the multiphase fluid mechanics particular to ice crystals, and explains how it differs from the established droplet multiphase flow, and the obstacles in implementing the former in computational analysis. A new modification of the Messinger thermal model is proposed to account for ice accretion produced by ice crystal impingement. Because there exist no computational and experimental ways to fully replicate ice crystal inflight icing, and because existing ice protections systems consume vast amounts of energy, a new ice protection device based on dielectric barrier discharge plasma is

    Full Text Available Potassium permanganate is a highly corrosive, water-soluble oxidizing antiseptic. A 68- year-old female patient was admitted to our Emergency Department after ingestion of 3 tablets of 250 mg potassium permanganate as a suicide attempt. The physical exam revealed brown stained lesions in the oropharynx. Emergency endoscopy was performed by the gastroenterologist after the third hour of ingestion. Emergency endoscopy revealed multiple superficial (Grade I-II lesions on the esophagus and cardia, which were considered secondary to the caustic substance. The mainstay in the treatment of potassium permanganate is supportive and the immediate priority is to secure the airway. Emergency endoscopy is an important tool used to evaluate the location and severity of injury to the esophagus, stomach and duodenum after caustic ingestion. Patients with signs and symptoms of intentional ingestion should undergo endoscopy within 12 to 24 h to define the extent of the disease.

    Most ingested foreign bodies will pass through the gastrointestinal tract without any problems. On the other hand long, slender objects such as a toothbrush will rarely be able to negotiate the angulated and fixed retroperitoneal duodenal loop. Spontaneous toothbrush passage has never been described and therefore endoscopic or surgical removal is always required. Here we describe an asymptomatic young female presenting to out-patient clinic with a history of unintentional toothbrush ingestion...

  1. Ingested foreign bodies in the paediatric patient.

    LENUS (Irish Health Repository)

    O'Brien, G C

    2012-02-03

    BACKGROUND: Paediatric foreign body (FB) ingestion is a common problem and while most can be managed conservatively, a sub-population require intervention. AIMS: To establish clear guidelines for management of paediatric FB ingestion. METHODS: A retrospective chart review analysing all paediatric admissions with FB ingestion over a 10-year period from 1990 to 1999. RESULTS: Of 339 patients presenting to the accident and emergency department with FB ingestion, 59 required admission. Ingestion was accidental in 93.0% of patients. The reasons for admission were as follows: large FBs; dangerous FBs; and living far from the hospital. Nineteen patients (32.2%) were discharged without intervention. Thirty-seven (62.7%) required endoscopic retrieval. In two, the FB was not identified at endoscopy. Only three (5%) required surgery. CONCLUSION: Conservative management of FB ingestion in the paediatric population is possible in the majority of cases. However, a minority require intervention. While guidelines for intervention are ill-defined, definitive indications include symptomatic patients, or dangerous objects.

    Amanita muscaria has a bright red or orange cap covered with small white plaques. It contains the isoxazole derivatives ibotenic acid, muscimol and muscazone and other toxins such as muscarine. The duration of clinical manifestations after A. muscaria ingestion does not usually exceed 24 hours; we report on a 5-day paranoid psychosis after A. muscaria ingestion. A 48-year-old man, with no previous medical history, gathered and ate mushrooms he presumed to be A. caesarea. Half an hour later he started to vomit and fell asleep. He was found comatose having a seizure-like episode. On admission four hours after ingestion he was comatose, but the remaining physical and neurological examinations were unremarkable. Creatine kinase was 8.33 microkat/l. Other laboratory results and brain CT scan were normal. Toxicology analysis did not find any drugs in his blood or urine. The mycologist identified A. muscaria among the remaining mushrooms. The patient was given activated charcoal. Ten hours after ingestion, he awoke and was completely orientated; 18 hours after ingestion his condition deteriorated again and he became confused and uncooperative. Afterwards paranoid psychosis with visual and auditory hallucinations appeared and persisted for five days. On the sixth day all symptoms of psychosis gradually disappeared. One year later he is not undergoing any therapy and has no symptoms of psychiatric disease. We conclude that paranoid psychosis with visual and auditory hallucinations can appear 18 hours after ingestion of A. muscaria and can last for up to five days.

  3. Estimates of soil ingestion by wildlife

    Science.gov (United States)

    Beyer, W.N.; Connor, E.E.; Gerould, S.

    1994-01-01

    Many wildlife species ingest soil while feeding, but ingestion rates are known for only a few species. Knowing ingestion rates may be important for studies of environmental contaminants. Wildlife may ingest soil deliberately, or incidentally, when they ingest soil-laden forage or animals that contain soil. We fed white-footed mice (Peromyscus leucopus) diets containing 0-15% soil to relate the dietary soil content to the acid-insoluble ash content of scat collected from the mice. The relation was described by an equation that required estimates of the percent acid-insoluble ash content of the diet, digestibility of the diet, and mineral content of soil. We collected scat from 28 wildlife species by capturing animals, searching appropriate habitats for scat, or removing material from the intestines of animals collected for other purposes. We measured the acid-insoluble ash content of the scat and estimated the soil content of the diets by using the soil-ingestion equation. Soil ingestion estimates should be considered only approximate because they depend on estimated rather than measured digestibility values and because animals collected from local populations at one time of the year may not represent the species as a whole. Sandpipers (Calidris spp.), which probe or peck for invertebrates in mud or shallow water, consumed sediments at a rate of 7-30% of their diets. Nine-banded armadillo (Dasypus novemcinctus, soil = 17% of diet), American woodcock (Scolopax minor, 10%), and raccoon (Procyon lotor, 9%) had high rates of soil ingestion, presumably because they ate soil organisms. Bison (Bison bison, 7%), black-tailed prairie dog (Cynomys ludovicianus, 8%), and Canada geese (Branta canadensis, 8%) consumed soil at the highest rates among the herbivores studied, and various browsers studied consumed little soil. Box turtle (Terrapene carolina, 4%), opossum (Didelphis virginiana, 5%), red fox (Vulpes vulpes, 3%), and wild turkey (Meleagris gallopavo, 9%) consumed soil

    The aim of the present study was to investigate esophageal motor function by means of krypton-81m esophageal transit scintigraphy and to compare the results with the functional and morphological data obtained by means of triple lumen manometry and endoscopy. In acute and subacute stages of the disease, all clinical, anatomical, and functional parameters were in good agreement, revealing significant impairment. In chronic stages, the severity of the dysphagia was not correlated to the importance of the residual stenosis. Conversely, 81mKr esophageal transit and manometric's findings were in good agreement with the clinical symptoms, during the entire follow-up period ranging between 3 months to 7 years. The 81mKr test is undoubtedly the easiest and probably the most physiological technique currently available for long-term functional evaluation of caustic esophagitis.

    We examined whether lipid metabolism in orchiectomised (ORX) rats was affected by fructose ingestion and the amount of ingested fructose. Sucrose was used as a fructose source. Sham-operated and ORX rats were fed one of the following three diets for 28 d: a maize starch-based diet without sucrose (SU0), a diet by which half or all of maize starch was replaced by sucrose (SU50 or SU100). Body-weight gain and food intake were increased by sucrose ingestion, but decreased by ORX. Plasma total cholesterol concentration was increased by ORX and dose-dependently by sucrose ingestion. Plasma TAG concentration was decreased by ORX, but was increased dose-dependently by sucrose ingestion. Plasma insulin concentration was decreased by ORX, but was not affected by sucrose ingestion. Liver TAG was increased by sucrose ingestion and ORX; however, liver cholesterol concentration was not affected by sucrose ingestion and ORX. The hepatic activity of cholesterol 7α-hydroxylase 1 was not affected by sucrose ingestion and ORX; however, faecal excretion of bile acids was decreased. The mRNA level of microsomal TAG transfer protein, which is the gene related to hepatic VLDL production, was increased by ORX and sucrose ingestion. The mRNA level of uncoupling protein-1 was decreased by ORX, but not by sucrose ingestion. Plasma insulin concentration tended to correlate with the level of sterol-regulatory element-binding protein-1c mRNA (r 0·747, P = 0·088). These results show that lipid metabolism in ORX rats would be affected by the consumption of fructose-rich sweeteners such as sucrose and high-fructose syrup.

    On May 24-25, 2005, the U.S. EPA Colloquium on Soil/Dust Ingestion Rates and Mouthing Behavior for Children and Adults (Colloquium) was held at the Holiday Inn National Airport in Crystal City, Virginia. The purpose of the Colloquium was to convene an expert panel to assess the state of knowledge on soil/dust ingestion research for children and adults. Because mouthing behavior is closely related to childrens soil and dust ingestion, mouthing behavior research also was included as a major topic. The Colloquium was designed to assist EPA in answering the following questions:What is the state of knowledge on soil/dust ingestion and mouthing behavior?Where should the state of knowledge be in order for EPA to make better decisions for the protection of children and adults from these pathways?How can EPA and the scientific community advance the science (i.e., what research is needed)?This summary report captures the major content of the presentations, breakout groups, and discussions/recommendations that occurred at the Colloquium. Presentation slides, organized sequentially by the order of presentation, the Colloquium agenda, and contact information of all the participants are included in this report as Appendices A, B, and C, respectively.

    Full Text Available Foreign body (FB ingestion is a common problem especially in children below the age of 5 years. This is fueled by their curiosity to explore their surroundings. The ingested foreign body finds its way out of the gastrointestinal tract without any serious consequences most of the time. On the other hand, disc battery ingestion has been reported to cause serious harm when ingested including death. We report two patients who had ingested disc batteries and their respective outcomes.

    The larval form of the moth Thaumetopoea pityocampa, known as pine processionary caterpillar, is one of the main forest pests in southern Europe. Often, these caterpillars cause local reactions in humans, due to their microscopic stinging hairs. Most symptoms affect skin, in form of acute urticaria. Systemic reactions are rare. An eleven month old infant with a systemic reaction after ingestion of a pine processionary caterpillar is presented. The boy reached the Emergency Room with orofacial edema, drooling and urticaria. Drug treatment was enough to resolve the symptoms. The patient did not present airway commitment, nor anaphylaxis data at any moment, so more aggressive actions, such as endotracheal intubation, endoscopy or laryngoscopy, were rejected.

  9. Stone ingestion causing obstructed inguinal hernia with perforation

    2014-01-01

    Full Text Available We report a rare case of obstructed right inguinal hernia caused by ingested stones. A 2 year-old boy from Northern Thailand was transferred to our hospital with low-grade fever, vomiting, and acute painful swelling at his right hemiscrotum for one day. The physical examination revealed marked enlargement with inflammation in his right hemiscrotum. The radiological findings showed huge number of stones in the right hemiscrotum. At surgery, the content of hernia sac was ascending colon, which was full of hard masses. With the help of additional lower transverse abdominal incision, the obstructed segment was successfully reduced and revealed a perforation. Most of the stones were removed through the perforation. The colonic wound was primarily repaired and both incisions were primarily closed. Although he developed post-operative wound infection, the boy had uneventfully recovered. The psychological exploration in this "stone pica" revealed no other psychological disorders.

    Metabolic models for U and Ra are described to estimate the risks to human health from ingesting these elements in drinking water. Chemical toxicity, which is relevant to U in its natural, depleted or slightly enriched state, is addressed, as are the radiotoxicity and the radiobiological effects of the important alpha-emitting isotopes of Ra, including /sup 224/Ra, /sup 226/Ra, and /sup 228/Ra. This paper estimates the kinetics of skeletal U deposition, so that risk coefficients for bone cancer induction can be applied. Skeletal cancer is regarded as the major potential radiobiological effect of ingested alpha-emitting radioisotopes of Ra and the presumed radiobiological effect of U, if any. Best estimates of normal U metabolism are used, because even in extreme cases the amounts of U or Ra ingested in potable water are not great enough to chemically or radiobiologically modify their metabolic behavior.

    Byard, Roger W

    2015-05-01

    The ingestion of corrosive substances may produce severe burns to the upper aerodigestive tract and stomach, particularly if the pH is greater than 12 or less than two. There is a biphasic age grouping with adult cases most often involving self-harm and pediatric cases accidental ingestion. Three cases are reported to demonstrate characteristic features following the ingestion of potassium hydroxide, glacial acetic acid and Lysol(®) , respectively. All deaths were due to the effects of caustic burns to the upper aerodigestive tract, esophagus and stomach with perforation and/or hemorrhage. The extent of injuries in these cases depends on the nature, amount, and concentration of the agent and on the exposure time. A point to note at autopsy is that tissue damage may also occur from postmortem exposure. Typical injuries involve perioral, limb, and trunk burns, with extensive aerodigestive liquefactive/coagulative necrosis causing hemorrhage and perforation.

We report the case of a five years old child, who presented, after ten bitter almonds ingestion, consciousness disorders progressing to coma with generalized tonic-clonic seizures, miosis and metabolic acidosis. Bitter almonds and nuclei of stone fruits or other rosaceae (apricot, peach, plum contain cyanogenic glycosides, amygdalin, that yields hydrogen cyanide when metabolized in the body. Swallowing six to ten bitter almonds may cause serious poisoning, while the ingestion of fifty could kill a man. The binding of cyanide ions on cytochrome oxidase lead to a non hypoxemic hypoxia by blocking the cellular respiratory chain. Therapeutic measures include, oxygen support, correction of acidosis and cyanide antidote by hydroxocobalamin in case of serious poisoning.

    Full Text Available Abstract Introduction Our aim was to specify the use of mini C-arm fluoroscopy in a woman with schizophrenia who was suffering from abdominal pain because of ingested needles. Case presentation Here we report the case of an 18-year-old Turkish woman with schizophrenia who was admitted to the emergency department with signs of an acute abdomen as a result of ingestion of multiple needles. This is the third case in the literature for which mini C-arm fluoroscopy has been used to localize metallic sewing needles. Conclusion When intentional ingestion occurs, surgery is rarely required. It is hard to localize ingested sewing needles and mini C-arm fluoroscopy is a good alternative when metal detectors are not available for localization of metal sewing needles. We recommend this approach because it helps to avoid unnecessary exploration, shortens the duration of surgery and provides outstanding results.

    Full Text Available The purpose of this investigation was to determine the efficacy of a moderate dose of caffeine to improve repeat-sprint performance in elite freestyle sprinters. Nine highly trained male swimmers performed 6 x 75 m freestyle sprints on two occasions 1-h after consuming either 3 mg·kg-1 caffeine (CAF, or placebo, in a cross-over manner. Capillary blood samples for the analysis of blood lactate concentration and pH were collected after the 1st, 3rd, and 5th sprint, while heart rate and perceived exertion (RPE were collected after every sprint. There was a moderate effect for improved mean sprint time in the CAF condition (0.52 s; 1.3%; d = 0.50. When assessed individually, there was a large effect for improved performance in sprints 3 (1.00 s; 2.5%; d = 1.02 and 4 (0.84 s; 2.1%; d = 0.84 in CAF compared to placebo, with worthwhile performance improvement found for each of the first 5 sprints. There was a significant treatment effect for higher blood lactate concentration for CAF (p = 0.029, and a significant treatment*time effect for reduced pH in the CAF condition (p = 0.004. Mean heart rate (167 ± 9 bpm vs 169 ± 7 bpm and RPE (17 ± 1 vs 17 ± 1 were not different between placebo and CAF trials, respectively. This investigation is the first to demonstrate enhanced repeat-sprint ability in swimmers following acute caffeine ingestion. It appears likely that the combination of a moderate dose of caffeine (3-6 mg·kg-1 with trained athletes is most likely to enhance repeat-sprint ability in various athletic populations; however, the exact mechanism(s for an improved repeat-sprint ability following acute caffeine ingestion remain unknown.

    The increased use of button batteries with high energy densities in devices of daily life presents a high risk of injury, especially for toddlers and young children. If an accidental ingestion of a button battery occurs, this foreign body can become caught in the constrictions of the esophagus and cause serious damage to the adjacent tissue layers. The consequences can be ulcerations, perforations with fistula formation and damage to the surrounding anatomical structures. In order to gain a better understanding of the pathophysiology after ingestion, we carried out systematic studies on fresh preparations of porcine esophagi. The lithium button battery type CR2032, used most frequently in daily life, was exposed in preparations of porcine esophagi and incubated under the addition of artificial saliva at 37 °C. A total of eight esophagi were analysed by different methods. Measurements of the pH value around the battery electrodes and histological studies of the tissue damage were carried out after 0.5-24 h exposure time. In addition, macroscopic time-lapse images were recorded. Measurements of the battery voltage and the course of the electric current supplemented the experiments. The investigations showed that the batteries caused an electrolysis reaction in the moist environment. The positive electrode formed an acidic and the negative electrode a basic medium. Consequently, a coagulation necrosis at the positive pole, and a deep colliquation necrosis at the minus pole occurred. After an exposure time of 12 h, tissue damage caused by the lye corrosion was observed on the side of the negative electrode up to the lamina muscularis. The corrosion progressed up to the final exposure time of 24 h, but the batteries still had sufficient residual voltage, such that further advancing damage would be expected. Button battery ingestion in humans poses an acute life-threatening danger and immediate endoscopic removal of the foreign body is essential. After only 2

    In this report, we describe a case of high anion gap metabolic acidosis with a significant osmolal gap attributed to the ingestion of liquor containing propylene glycol. Recently, several reports have characterized severe lactic acidosis occurring in the setting of iatrogenic unintentional overdosing of medications that use propylene glycol as a diluent, including lorazepam and diazepam. To date, no studies have explored potential effects of excess propylene glycol in the setting of alcohol intoxication. Our patient endorsed drinking large volumes of cinnamon flavored whiskey, which was likely Fireball Cinnamon Whisky. To our knowledge, this is the first case of propylene glycol toxicity from an intentional ingestion of liquor containing propylene glycol. PMID:26904700

    Camphor is a cyclic ketone of the hydro aromatic terpene group. Today it is frequently used as a prescription or non-prescription topical antitussive, analgesic, anesthetic and antipruritic agent. Camphor which is considered an innocent drug by parents and physicians is a common household item which can lead to severe poisoning in children even when taken in small amounts. Neurotoxicity in the form of seizures can ocur soon after ingestion. A two-year old female patient who presented with a complaint of generalized tonic-clonic seizures after oral ingestion of camphor is presented.

    Full Text Available Hydrogen peroxide is a commonly used oxidizing agent with a variety of uses depending on its concentration. Ingestion of hydrogen peroxide is not an uncommon source of poisoning, and results in morbidity through three main mechanisms: direct caustic injury, oxygen gas formation and lipid peroxidation. A case of a 39-year-old man who inadvertently ingested 250 mL of unlabelled 35% hydrogen peroxide intended for natural health use is presented. Hydrogen peroxide has purported benefits ranging from HIV treatment to cancer treatment. Its use in the natural health industry represents an emerging source for accidental poisonings.

    We report a case of intestinal perforation in a 20 month old girl following the ingestion of 2 small magnets. Ingestion of multiple magnets constitutes a unique problem. Magnets in adjacent intestinal loops may forcefully attract each other and produce pressure necrosis of the bowel wall, leading to perforation, fistula formation or intestinal obstruction. Therefore, these children should be observed carefully. Early surgical intervention should be considered when clinical symptoms develop, especially when, on sequential abdominal radiographs, there is no change in the magnets' location. Since toys with small magnets are ubiquitous, efforts should be made to increase parents' awareness on the one hand, and to alert toy manufacturers on the other hand.

Key points A moderate dose of caffeine (3 mg·kg-1) ingested 1 h before a repeat-sprint freestyle set significantly improves mean sprint time in elite swimmers. The combination of at least a moderate dose of caffeine (>3 mg·kg-1) with trained athletes appears the most likely to result in ergogenic benefit to anaerobic

    Ingestion of marine debris can have lethal and sublethal effects on sea turtles and other wildlife. Although researchers have reported on ingestion of anthropogenic debris by marine turtles and implied incidences of debris ingestion have increased over time, there has not been a global synthesis of the phenomenon since 1985. Thus, we analyzed 37 studies published from 1985 to 2012 that report on data collected from before 1900 through 2011. Specifically, we investigated whether ingestion prevalence has changed over time, what types of debris are most commonly ingested, the geographic distribution of debris ingestion by marine turtles relative to global debris distribution, and which species and life-history stages are most likely to ingest debris. The probability of green (Chelonia mydas) and leatherback turtles (Dermochelys coriacea) ingesting debris increased significantly over time, and plastic was the most commonly ingested debris. Turtles in nearly all regions studied ingest debris, but the probability of ingestion was not related to modeled debris densities. Furthermore, smaller, oceanic-stage turtles were more likely to ingest debris than coastal foragers, whereas carnivorous species were less likely to ingest debris than herbivores or gelatinovores. Our results indicate oceanic leatherback turtles and green turtles are at the greatest risk of both lethal and sublethal effects from ingested marine debris. To reduce this risk, anthropogenic debris must be managed at a global level. © 2013 The Authors.

    Chlorfenapyr has been used worldwide for agricultural pest control since 1995. Despite its widespread use, acute human poisoning data are insufficient; only a small number of fatalities from chlorfenapyr poisoning have been reported. The signs and symptoms of chlorfenapyr toxicity include nausea, vomiting, fever, rhabdomyolysis, among others. In addition, central nervous system effects in association with delayed toxicity have also been observed. Here, we detail a fatality resulting from delayed chlorfenapyr toxicity following the ingestion of a small amount of pesticide.

    Although the multi-component weight loss supplement Redotex is banned in the United States, the supplement can be obtained in Mexico. The intent of this report was to describe the pattern of Redotex calls received by a statewide poison center system. Cases were all Redotex calls received by Texas poison centers during 2000-2008. The distribution of total calls and those involving ingestion of the supplement were determined for selected demographic and clinical factors. Of 34 total Redotex calls received, 55.9% came from the 14 Texas counties that border Mexico. Of the 22 reported Redotex ingestions, 77.3% of the patients were female and 45.5% 20 years or more. Of the 17 ingestions involving no co-ingestants, 52.9% were already at or en route to a health care facility, 41.2% were managed on site, and 5.9% was referred to a health care facility. The final medical outcome was no effect in 23.5% cases, minor effect in 5.9%, moderate effect in 11.8%, not followed but minimal clinical effects possible in 47.1%, and unable to follow but judged to be potentially toxic in 11.8%. Most Redotex calls to the Texas poison center system originated from counties bordering Mexico.

    Ingestion of fatty foods increases dopamine release in the substantianigra producing a positive hedonic state. Tellez et al. (2013) demonstrate that an intestinal signal generated by fat consumption, oleoylethanolamide, stimulates central dopamine activity, thus regulating the reward value of fat and establishing a link between caloric-homeostatic and hedonic-homeostatic controllers.

    The production of odorous urine after the ingestion of asparagus has been shown to occur in 43% of 800 volunteers investigated. This characteristic is reproducible over a 12-month-period and has been shown to remain with individuals for virtually a lifetime. Family studies suggest that the ability to produce the odorous urine is inherited as an autosomal dominant trait.

    Full Text Available In non-febrile mouse models, high dose acetaminophen administration causes profound hypothermia. However, this potentially hazardous side-effect has not been confirmed in non-febrile humans. Thus, we sought to ascertain whether an acute therapeutic dose (20 mg·kg lean body mass of acetaminophen would reduce non-febrile human core temperature in a sub-neutral environment. Ten apparently healthy (normal core temperature, no musculoskeletal injury, no evidence of acute illness Caucasian males participated in a preliminary study (Study one to determine plasma acetaminophen concentration following oral ingestion of 20 mg·kg lean body mass acetaminophen. Plasma samples (every 20 minutes up to 2-hours post ingestion were analysed via enzyme linked immunosorbent assay. Thirteen (eight recruited from Study one apparently healthy Caucasian males participated in Study two, and were passively exposed to 20°C, 40% r.h. for 120 minutes on two occasions in a randomised, repeated measures, crossover design. In a double blind manner, participants ingested acetaminophen (20 mg·kg lean body mass or a placebo (dextrose immediately prior to entering the environmental chamber. Rectal temperature, skin temperature, heart rate, and thermal sensation were monitored continuously and recorded every ten minutes. In Study one, the peak concentration of acetaminophen (14 ± 4 µg/ml in plasma arose between 80 and 100 minutes following oral ingestion. In Study two, acetaminophen ingestion reduced the core temperature of all participants, whereas there was no significant change in core temperature over time in the placebo trial. Mean core temperature was significantly lower in the acetaminophen trial compared with that of a placebo (p 0.05. The results indicate oral acetaminophen reduces core temperature of humans exposed to an environment beneath the thermal neutral zone. These results suggest that acetaminophen may inhibit the thermogenic mechanisms required to regulate

    Similar to effects of alcohol on the heart, liver, and brain, the effects of ethanol (EtOH) on lung injury are preventable. Unlike other vital organ systems, however, the lethal effects of alcohol on the lung are underappreciated, perhaps because there are no signs of overt pulmonary disorder until a secondary insult, such as a bacterial infection or injury, occurs in the lung. This paper provides overview of the complex changes in the alveolar environment known to occur following both chronic and acute alcohol exposures. Contemporary animal and cell culture models for alcohol-induced lung dysfunction are discussed, with emphasis on the effect of alcohol on transepithelial transport processes, namely, epithelial sodium channel activity (ENaC). The cascading effect of tissue and phagocytic Nadph oxidase (Nox) may be triggered by ethanol exposure, and as such, alcohol ingestion and exposure lead to a prooxidative environment; thus impacting alveolar macrophage (AM) function and oxidative stress. A better understanding of how alcohol changes the landscape of the alveolar epithelium can lead to improvements in treating acute respiratory distress syndrome (ARDS) for which hospitalized alcoholics are at an increased risk.

    Skeletal muscle blood flow is attenuated in aged humans performing dynamic exercise, which is due, in part, to impaired local vasodilatory mechanisms. Recent evidence suggests that folic acid improves cutaneous vasodilation during localized and whole body heating through nitric oxide-dependent mechanisms. However, it is unclear whether folic acid improves vasodilation in other vascular beds during conditions of increased metabolism (i.e., exercise). The purpose of this study was to test the hypothesis that folic acid ingestion improves skeletal muscle blood flow in aged adults performing graded handgrip and plantar flexion exercise via increased vascular conductance. Nine healthy, aged adults (two men and seven women; age: 68 ± 5 yr) performed graded handgrip and plantar flexion exercise before (control), 2 h after (acute, 5 mg), and after 6 wk (chronic, 5 mg/day) folic acid ingestion. Forearm (brachial artery) and leg (superficial femoral artery) blood velocity and diameter were measured via Duplex ultrasonography and used to calculate blood flow. Acute and chronic folic acid ingestion increased serum folate (both P < 0.05 vs. control). During handgrip exercise, acute and chronic folic acid ingestion increased forearm blood flow (both conditions P < 0.05 vs. control) and vascular conductance (both P < 0.05 vs. control). During plantar flexion exercise, acute and chronic folic acid ingestion increased leg blood flow (both P < 0.05 vs. control), but only acute folic acid ingestion increased vascular conductance (P < 0.05 vs. control). Taken together, folic acid ingestion increases blood flow to active skeletal muscle primarily via improved local vasodilation in aged adults.NEW & NOTEWORTHY Our findings demonstrate that folic acid ingestion improves blood flow via enhanced vascular conductance in the exercising skeletal muscle of aged humans. These findings provide evidence for the therapeutic use of folic acid to improve skeletal muscle blood flow, and perhaps

    Marine turtles are an iconic group of endangered animals threatened by debris ingestion. However, key aspects related to debris ingestion are still poorly known, including its effects on mortality and the original use of the ingested debris. Therefore, we analysed the impact of debris ingestion in 265 green turtles (Chelonia mydas) over a large geographical area and different habitats along the Brazilian coast. We determined the death rate due to debris ingestion and quantified the amount of debris that is sufficient to cause the death of juvenile green turtles. Additionally, we investigated the original use of the ingested debris. We found that a surprisingly small amount of debris was sufficient to block the digestive tract and cause death. We suggested that debris ingestion has a high death potential that may be masked by other causes of death. An expressive part of the ingested debris come from disposable and short-lived products.

    Foreign body ingestion (FBI) is a common problem in the pediatric population. Even though morbidity and mortality due to foreign body ingestion are rare in childhood, they may cause serious anxiety in parents. We aimed to analyze the clinical presentation, etiology and management strategy of FBI in children in our country. Records of children admitting with a history of FBI over a three-year period were reviewed retrospectively. Data regarding gender, age, type of the ingested body, management strategy and outcome of the patients were recorded. Of 176 children, 98 (55.6%) were male. Mean age +/- SD of the patients was 3.75 +/- 4.25 years, and most of the patients were below four years of age (71.5%). Most of the children (64.7%) were seen within 48 hours, and most were asymptomatic. Blue beads attached to a safety pin (a cultural good luck charm) (38.6%), coins (27.8%) and turban pins (18.1%) were the most commonly observed foreign bodies. The blue beads/safety pin were found to be ingested primarily by infants, while ingestion of turban pins was mostly seen in adolescent girls who covered their heads. Localization of the foreign bodies was in the distal small intestine, stomach and esophagus in 61.4%, 23.8% and 14.7% of the cases, respectively. Sixty-nine endoscopic interventions were performed in 61 patients (34.6%), and these accounted for 7.3% of all endoscopic interventions during the three-year period. No major complication was observed during the procedure, and none of the patients underwent surgery. The frequently used accessory devices were retrieval net basket (57.9%), snare for pins (17.3%), tripod forceps and rat-tooth forceps. The blue beads/safety pin and turban pin were the commonly ingested foreign bodies in our center due to cultural factors. Education of the parents and of adolescent girls should greatly reduce the incidence of FBI. Endoscopic removal is safe without any major complications.

    Physiological conditions in humans affect plasma amino acid profiles that might have potential for medical use. Because the branched-chain amino acids (BCAAs) leucine, isoleucine and valine are used as medicines and supplements, we investigated the acute effects of individual BCAAs (10-90 mg/kg body weight) or mixed BCAAs ingested as a bolus on plasma amino acid profiles in young healthy men. Plasma leucine levels rapidly increased and peaked around 30 min after leucine ingestion. Concentrations of plasma isoleucine, valine and phenylalanine subsequently decreased after ingestion, and those of methionine and tyrosine tended to decrease. The effects of ingested leucine on other plasma amino acids were biphasic, being higher at lower doses (10-20 mg/kg body weight). Isoleucine or valine intake also caused corresponding plasma amino acid concentrations to rapidly elevate, and peaks at 30-40 min after ingestion were much higher than that of plasma leucine after leucine ingestion. However, the increase in plasma isoleucine and valine concentrations essentially did not affect those of other plasma amino acids. The rate of decline among peak plasma BCAA concentrations was the highest for leucine, followed by isoleucine and valine. Oral mixed BCAAs promoted the decline in plasma isoleucine and valine concentrations. These results suggest that plasma leucine is a regulator of the plasma concentrations of BCAAs, methionine and aromatic amino acids.

Recently, several reports have characterized severe lactic acidosis occurring in the setting of iatrogenic unintentional overdosing of medications that use propylene glycol as a diluent, including lorazepam and diazepam. To date, no studies have explored potential effects of excess propylene glycol in the setting of alcohol intoxication. Our patient endorsed drinking large volumes of cinnamon flavored whiskey, which was likely Fireball Cinnamon Whisky. To our knowledge, this is the first case of propylene glycol toxicity from an intentional ingestion of liquor containing propylene glycol.

    Most ingested foreign bodies will pass through the gastrointestinal tract without any problems. On the other hand long, slender objects such as a toothbrush will rarely be able to negotiate the angulated and fixed retroperitoneal duodenal loop. Spontaneous toothbrush passage has never been described and therefore endoscopic or surgical removal is always required. Here we describe an asymptomatic young female presenting to out-patient clinic with a history of unintentional toothbrush ingestion 4 years prior. Endoscopic removal was unsuccessful because the toothbrush was partially embedded in to the gastric mucosa. We describe the second case to date of laparoscopic removal of a toothbrush via a gastrotomy with subsequent intra-corporeal repair of the defect.

    The Danish National Archives, and The Royal Library and the State and University Library are in the process of developing a cost model for digital preservation: Each of the functional entities of the OAIS Reference Model are broken down into measurable, cost-critical activities, and formula...... are being tailored for each of these in order to create a generic tool for estimating the short and long-term costs of digital preservation. This paper presents an introduction to the subject of the costs of digital preservation and describes the method used to develop the Danish Cost Model for Digital...... Preservation (CMDP). It then describes how the OAIS functional entity, Ingest, has been included in the model. For institutions basing their digital preservation strategy on migration, a major cost pertaining to Ingest is normalization, a digital migration from production to preservation format and structure...

    Previous studies have indirectly shown that type 1 gonococci are more resistant to phagocytosis by human neutrophils (PMN) than type 3 gonococci. Using phase contrast, fluorescent, and light microscopy, we directly quantitated PMN-gonococcal interaction, with emphasis on separating ingestion from attachment. PMN monolayers were incubated on slides with type 1 or type 3 gonococcal fluorescent antibody (FA). After methanol fixation, the FA-stained gonococci associated with PMN were cointed. Since the live PMN excludes FA, the FA-stained gonococci represent only extracellular gonococci. Methylene blue was then added to the smae slide to stain both ingested and surface attached gonococci. Using these methods, intracellular and extracellular cell-associated gonococci were quantitated under varying conditions. The numbers of methylene blue-stained cell-associated gonococci that were ingested were: with normal serum, 3.7 plus or minus 4.1 per cent for type 1 and 56.2 plus or minus 3.7 percent for type 3 (P smaller than 0.001); with heat-inactivated serum, 1.0 plus or minus 3.0 per cent for type 1 and 52.6 plus or minus 3.7 per cent for type 3 (P smaller than 0.001); with higher-titer anti-gonococcal antibody serum, 4.8 plus or minus 4.3 percent for type 1 and 64.0 plus or minus 1.6 per cent for type 3 (P smaller than 0.001). Thus, most type 3 organisms were ingested, but most type 1 gonococci were bound on the PMN surface.

    Toddlers who ingest the drug of abuse 3,4-methylenedioxymethamphetamine (MDMA; 'Ecstasy') are at particularly high risk of serious neurological and cardiovascular side effects. We report of a 20-month-old male toddler who accidentally ingested Ecstasy. He presented with fever and seizures, tachycardia, hypertension, and hyperthermia. Urine amphetamine level was 2111 ng/mL. Treatment included rapid cooling, hydration, and support measures. Vital signs were regularly monitored. His condition became stable on day 2 and urine amphetamine level returned to normal on day 3 of hospitalization. His behavior, activity, and appetite had returned to their usual levels upon follow-up at our outpatient clinic. The incidence of drug abuse with MDMA has increased dramatically over the last decade in developed countries. It can be expected that accidental Ecstasy poisoning in children will increase as well. This case illustrates the need to consider the possibility of accidental Ecstasy ingestion in the differential diagnosis of a child suffering from convulsions with fever.

    Full Text Available Ingestion of foreign bodies in the pediatric population is common and magnet ingestion is known to cause a significant morbidity. Rare-earth magnets are small 3–6 mm diameter spherical powerful magnets that are sold as popular desk toys for adults and were previously found in construction toys in attractive colors for children to play with. We describe 2 young healthy children who ingested rare-earth magnets Buckyballs while playing with these magnetic toys and later presented in emergency with acute abdomen. Abdominal imaging revealed several (26 and 5 pieces of rare-earth magnets in the bowel loops. Emergency surgical exploration revealed multiple gastrointestinal perforations and fistula formation at sites of bowel entrapment in between strong magnets apposed to one another. We highlight the potential dangers of rare-earth magnets in children and suggest increasing public awareness about risks involved in rare-earth magnets ingestion by children to overcome this serious public health issue.

    Acute symptomatic hyponatremia after ecstasy (3,4 methyldioxymethamphetamine; MDMA) ingestion is well documented and has been attributed to the syndrome of inappropriate antidiuretic hormone (SIADH). We report the case of an 18-year-old woman who took five tablets of ecstasy in a suicide attempt and drank 1700 ml water at the Emergency Department (ED). The laboratory findings obtained 5 h after ingestion showed a serum sodium concentration of 130 mmol/l, plasma osmolality of 264 mOsm/kg, urinary osmolality of 335 mOsm/kg and natriuresis of 101 mmol/l. The plasma arginine vasopressin level by radioimmunoassay was 33.7 pmol/l 5 h after ingestion. A gas chromatography-mass spectrometry assay confirmed MDMA in blood samples, with serum concentrations of 0.87 mg/l on arrival. This case report strongly suggests that MDMA reduces serum sodium levels through the dual pathways of SIADH and polydipsia. Accordingly, we believe that hyponatremia may be prevented in ED patients after MDMA ingestion by the early restriction of water intake.

    Green tea consumption is reportedly associated with various health-promoting properties. For example, it has been shown to promote fat oxidation in humans at rest and to prevent obesity and improve insulin sensitivity in mice. We investigated the effects of acute ingestion of green tea extract (GTE) on glucose tolerance and fat oxidation during moderate-intensity exercise in humans. Two studies were performed, both with a counter-balanced crossover design. In study A, 12 healthy men performed a 30-min cycling exercise at 60% of maximal oxygen consumption (VO2max) before and after supplementation. In study B, 11 healthy men took an oral-glucose-tolerance test before and after supplementation. In the 24-h period before the experimental trials, participants ingested 3 capsules containing either GTE (total: 890 +/- 13 mg polyphenols and 366 +/- 5 mg EGCG) or a corn-flour placebo (total: 1729 +/- 22 mg). Average fat oxidation rates were 17% higher after ingestion of GTE than after ingestion of placebo (0.41 +/- 0.03 and 0.35 +/- 0.03 g/min, respectively; P fat oxidation to total energy expenditure was also significantly higher, by a similar percentage, after GTE supplementation. The insulin area under the curve decreased in both the GTE and placebo trials (3612 +/- 301 and 4280 +/- 309 microIU/dL . 120 min, respectively; P fat oxidation during moderate-intensity exercise and can improve insulin sensitivity and glucose tolerance in healthy young men.

    Smoking has a thermogenic effect and is associated with low physical performance. Nevertheless, a direct, quantitative effect of acute smoking on exercise heat tolerance has not been reported. Sixteen healthy young male volunteers, eight cigarette smokers, and eight non-smokers participated in the study. All subjects performed a maximal oxygen consumption test (VO2max) and a standardized heat tolerance test (HTT) after at least 12 h without smoking under the following conditions: no nicotine exposure, 10 min after nicotine exposure (2 mg nicotine lozenge), and 10 min after smoking two cigarettes (0.8 mg nicotine in each cigarette, smokers only). There was no significant effect of nicotine exposure on physiological performance and heat tolerance in the non-smokers group. In the smokers group, cigarette smoking, but not nicotine ingestion, resulted with higher heart rate (by 9±9 bpm) at the end of the HTT (psmoking and nicotine ingestion increased smokers' rectal temperature at the end of the HTT (by 0.24±0.16°C and 0.21±0.26°C, respectively, psmoking in the smokers group compared with no exposure (2.13±2.57 and 2.48±2.76, respectively, psmoking and nicotine ingestion increase the physiological strain during a HTT in smokers. Acute smoking may, therefore, increase heat intolerance and the risk to heat injuries.

    Full Text Available Introduction: Acute toxic ingestion is a common cause of morbidity and mortality. Emergency physicians (EP caring for overdose (OD patients are often required to make critical decisions with incomplete information. Point of care ultrasound (POCUS may have a role in assisting EPs manage OD patients. We evaluated the impact of different liquid adjuncts used for gastric decontamination on examiners’ ability to identify the presence of tablets using POCUS, and assessed examiners’ ability to quantify the numbers of tablets in a simulated massive OD. Methods: This prospective, blinded, pilot study was performed at an academic emergency department. Study participants were volunteer resident and staff EPs trained in POCUS. Five non-transparent, sealed bags were prepared with the following contents: 1 liter (L of water, 1 L of water with 50 regular aspirin (ASA tablets, 1 L of water with 50 enteric-coated aspirin tablets (ECA, 1 L of polyethylene glycol (PEG with 50 ECA, and 1 L of activated charcoal (AC with 50 ECA. After performing POCUS on each of the bags using a 10-5 MHz linear array transducer, participants completed a standardized questionnaire composed of the following questions: (1 Were pills present? YES/NO; (2 If tablets were identified, estimate the number (1-10, 11-25, >25. We used a single test on proportions using the binomial distribution to determine if the number of EPs who identified tablets differed from 50% chance. For those tablets identified in the different solutions, another test on proportions was used to determine whether the type of solution made a difference. Since 3 options were available, we used a probability of 33.3%. Results: Thirty-seven EPs completed the study. All (37/37 EP’s correctly identified the absence of tablets in the bag containing only water, and the presence of ECA in the bags containing water and PEG. For Part 2 of the study, most participants - 25/37 (67.5% using water, 23/37 (62.1% using PEG, and

  11. Hemorrhagic shock secondary to button battery ingestion

    Directory of Open Access Journals (Sweden)

    Naomi Andreia Takesaki

    Full Text Available CONTEXT:Button battery ingestion is a frequent pediatric complaint. The serious complications resulting from accidental ingestion have increased significantly over the last two decades due to easy access to gadgets and electronic toys. Over recent years, the increasing use of lithium batteries of diameter 20 mm has brought new challenges, because these are more detrimental to the mucosa, compared with other types, with high morbidity and mortality. The clinical complaints, which are often nonspecific, may lead to delayed diagnosis, thereby increasing the risk of severe complications.CASE REPORT:A five-year-old boy who had been complaining of abdominal pain for ten days, was brought to the emergency service with a clinical condition of hematemesis that started two hours earlier. On admission, he presented pallor, tachycardia and hypotension. A plain abdominal x-ray produced an image suggestive of a button battery. Digestive endoscopy showed a deep ulcerated lesion in the esophagus without active bleeding. After this procedure, the patient presented profuse hematemesis and severe hypotension, followed by cardiorespiratory arrest, which was reversed. He then underwent emergency exploratory laparotomy and presented a new episode of cardiorespiratory arrest, which he did not survive. The battery was removed through rectal exploration.CONCLUSION:This case describes a fatal evolution of button battery ingestion with late diagnosis and severe associated injury of the digestive mucosa. A high level of clinical suspicion is essential for preventing this evolution. Preventive strategies are required, as well as health education, with warnings to parents, caregivers and healthcare professionals.

    The purpose of this article is to review the recent literature that documents the serious adverse systemic effects of prolonged, excessive zinc ingestion from the overuse of denture adhesives. This condition causes elevation of serum zinc levels that result in depression of serum copper. The low serum copper levels cause bone marrow depression and widespread sensory and motor neuropathies. Epidemiologic studies revealed the source of excessive zinc intake to be from overuse of denture adhesives. Denture patients must be advised of the risks of prolonged overuse of denture adhesives.

    Mostly ingested button batteries passed through the gastrointestinal tract without any adverse effects. But button battery can lead to hazardous complications including tracheoesophageal fistula (TEF), especially when the battery is impacted in the esophagus. Urgent esophagoscopic removal of the battery is essential in all cases. Once the TEF is identified, conservative management is the initial treatment of choice. Delayed primary repair can be tried if spontaneous closure does not occur. Here in we want to report a rare case of air leak syndrome, pneumo-pericardium secondary to the corrosive effect of a button battery and child recovered completely with conservative management.

    Oxytocin knockout (OT KO) mice acutely consume inappropriate amounts of sodium following overnight water deprivation suggesting that oxytocinergic neurons inhibit excessive sodium ingestion (Amico JA, Morris M, Vollmer RR. Mice deficient in oxytocin manifest increased saline consumption following overnight fluid deprivation. Am J Physiol - Regul Integr Comp Physiol 2001; 281:R1368-R1373). This study sought to determine whether oxytocin (OT) provides long-term regulation of voluntary sodium ingestion. Wild-type (WT) and oxytocin knockout male mice were provided choices between diets or drinking solutions that differed in their sodium content. Mice were given access for 1 week to two diets, one containing low sodium (0.01% sodium chloride [NaCl]) content and a second containing a normal sodium (1.0% NaCl) content. During the second week, the animals were given a choice between a low sodium diet and a high sodium (8.0% NaCl) diet. In the second week, mice consumed 4 times more sodium; however, there were no differences between WT and OT KO mice. In a second experiment, mice had access to a two-bottle choice of tap water and a 0.5 M NaCl solution made palatable by the addition of a 4.1% Intralipid emulsion. Both genotypes consumed large, but equivalent, volumes of the Intralipid/sodium solution. The ingestion of this sodium-rich solution stimulated thirst and enhanced the intake of water. Thus, the availability of palatable sodium-rich food or solutions can lead to excessive voluntary sodium ingestion. Compared with oxytocin knockout mice, enhanced voluntary ingestion of sodium-rich solid and liquid diets proceeded unimpeded in WT mice. Therefore, OT pathways may not be essential for regulating solute intake in this setting.

    Ingestible electronics have revolutionized the standard of care for a variety of health conditions. Extending the capacity and safety of these devices, and reducing the costs of powering them, could enable broad deployment of prolonged monitoring systems for patients. Although prior biocompatible power harvesting systems for in vivo use have demonstrated short minute-long bursts of power from the stomach, not much is known about the capacity to power electronics in the longer term and throughout the gastrointestinal tract. Here, we report the design and operation of an energy-harvesting galvanic cell for continuous in vivo temperature sensing and wireless communication. The device delivered an average power of 0.23 μW per mm(2) of electrode area for an average of 6.1 days of temperature measurements in the gastrointestinal tract of pigs. This power-harvesting cell has the capacity to provide power for prolonged periods of time to the next generation of ingestible electronic devices located in the gastrointestinal tract.

    Full Text Available A ocorrência de toxoplasmose aguda em três membros de uma mesma família foi relacionada à ingestão de leite de cabra, não pasteurizado e nem fervido. As cabras eram criadas soltas no peridomicílio para fornecimento de leite. Anticorpos fluorescentes anti-Toxoplasma foram detectados nos quinze animais examinados, sendo que oito caprinos apresentaram títulos superiores a 1:1024 e nas cinco cabras lactantes estes títulos variaram de 1:1024 a 1:32.768. Taquizoitos foram isolados, por inovulação em camundongos, do leite de uma destas cabras. Os cães criados na mesma casa não apresentaram sintomas de toxoplasmose apesar de ter ocorrido perda de ninhada de uma cadela; em todos os cães foram detectados baixos níveis de anticorpos. Foi considerada menos provável a possibilidade de que as infecções humanas pudessem ser devido à ingestão de alimentos contaminados com oocistos.Acute toxoplasmosis in three members of the same family was related to drinking unpasteurized goat's milk. The goats were reared, for milk production in a peri-domestic area. Based on indirect immunofluorescent reactions antibody titers greater than 1: 1024 were recorded in eight out of fifteen animals examined and were highest in the five lactating adult females. Toxoplasma was isolated, by inoculation of mice, from the milk of one these females. Dogs reared in the same house showed no symptoms of acute toxoplasmosis and low antibody titers were detected in these animals. It was also found that the humaninfections could not have been due to the ingestion of food contaminated with oocysts.

    Full Text Available Alkaline batteries have become the second most swallowed foreign bodies following coins. Most cases have an uncomplicated course, but some may lead to serious complications and even death. Here we report a 28 months old boy who had experienced discomfort, eating refusal, vomiting and slightly wheezing after falling from a sofa bed. He has been in three different county hospitals and two private hospitals due to complaints, has been examined by two pediatricians and a cranial surgeon. A cranial CT imaging, a cranial X-ray radiograph and a chest X-ray radiograph was obtained. Firstly, diagnosed as head and neck trauma, then diagnosed as acute bronchiolitis, and finally pneumonia. Hospitalized twice. Finally, a chest radiograph revealed a button battery in the esophagus. The foreign body was endoscopic removed. The child had a quick clinical impairment after removal of the battery. As a result, alkaline batteries with their increasing risk of engulfment poses very serious problems. The parents and physicians should be informed against increasing frequency of ingestion of alkaline batteries by infants and children. Also, clinicians should be careful about the risk of these batteries that they can cause pneumonia and infiltration which may make it difficult to detect the foreign body.

    Unintentional acid ingestion is less commonly encountered than alkali ingestion. The injury develops for hours to days after ingestion and often results in progressively increasing difficulty in airway management. However, gastric perforation is rare. A 3-year-old boy presented to us with an orotonsillopharyngeal membrane and severe upper airway obstruction. Subsequently, he was diagnosed with a case of gastric perforation due to unintentional hydrochloric acid ingestion. He was treated with partial gastrectomy and feeding jejunostomy, and the recovery was good. Unintentional hydrochloric acid ingestion is rare in children. The manifestations masquerade many other clinical conditions, and the diagnosis is difficult in cases in which history of ingestion is not available. Treatment is symptomatic, and emergency surgery is indicated in case of gastrointestinal perforation.

    AXAIRQ is a dose mode code used for prospective accident assessment at the Savannah River Site and is primarily used to show regulatory compliance. For completeness of pathway analysis, an ingestion model, AXINGST, has been developed for use with, and incorporation in, AXAIRQ. Currently available ingestion models were referenced as a basis for AXINGST. AXINGST calculates a conservative ingestion dose following an atmospheric release of radionuclides and includes site specific variables where applicable.

  3. Analgesia accompanying food consumption requires ingestion of hedonic foods.

    Animals eat rather than react to moderate pain. Here, we examined the behavioral, hedonic, and neural requirements for ingestion analgesia in ad libitum fed rats. Noxious heat-evoked withdrawals were similarly suppressed during self-initiated chocolate eating and ingestion of intraorally infused water, sucrose, or saccharin, demonstrating that ingestion analgesia does not require feeding motivation, self-initiated food procurement, sucrose, or calories. Rather, food hedonics is important because neither salt ingestion nor quinine rejection elicited analgesia. During quinine-induced nausea and lipopolysaccharide (LPS)-induced illness, conditions when chocolate eating was presumably less pleasurable, analgesia accompanying chocolate consumption was attenuated, yet analgesia during water ingestion was preserved in LPS-injected rats who showed enhanced palatability for water within this context. The dependence of ingestion analgesia on the positive hedonics of an ingestate was confirmed in rats with a conditioned taste aversion to sucrose: after paired exposure to sucrose and LPS, rats no longer showed analgesia during sucrose ingestion but continued to show analgesia during chocolate consumption. Eating pauses tended to occur less often and for shorter durations in the presence of ingestion analgesia than in its absence. Therefore, we propose that ingestion analgesia functions to defend eating from ending. Muscimol inactivation of the medullary raphe magnus blocked the analgesia normally observed during water ingestion, showing the involvement of brainstem endogenous pain inhibitory mechanisms in ingestion analgesia. Brainstem-mediated defense of the consumption of palatable foods may explain, at least in part, why overeating tasty foods is so irresistible even in the face of opposing cognitive and motivational forces.

    Anthropogenic debris in the world's oceans and coastal environments is a pervasive global issue that has both direct and indirect impacts on avifauna. The number of bird species affected, the feeding ecologies associated with an increased risk of debris ingestion, and selectivity of ingested debris have yet to be investigated in most of Australia's coastal and marine birds. With this study we aim to address the paucity of data regarding marine debris ingestion in Australian coastal and marine bird species. We investigated which Australian bird groups ingest marine debris, and whether debris-ingesting groups exhibit selectivity associated with their taxonomy, habitat or foraging methods. Here we present the largest multispecies study of anthropogenic debris ingestion in Australasian avifauna to date. We necropsied and investigated the gastrointestinal contents of 378 birds across 61 species, collected dead across eastern Australia. These species represented nine taxonomic orders, five habitat groups and six feeding strategies. Among investigated species, thirty percent had ingested debris, though ingestion did not occur uniformly within the orders of birds surveyed. Debris ingestion was found to occur in orders Procellariiformes, Suliformes, Charadriiformes and Pelecaniformes, across all surveyed habitats, and among birds that foraged by surface feeding, pursuit diving and search-by-sight. Procellariiformes, birds in pelagic habitats, and surface feeding marine birds ingested debris with the greatest frequency. Among birds which were found to ingest marine debris, we investigated debris selectivity and found that marine birds were selective with respect to both type and colour of debris. Selectivity for type and colour of debris significantly correlated with taxonomic order, habitat and foraging strategy. This study highlights the significant impact of feeding ecology on debris ingestion among Australia's avifauna.

    Full Text Available Button battery ingestion is an emerging hazard. In this retrospective study, we report six cases of lithium button battery ingestion in pediatric age group (mean age 2.8 years. Three button batteries were removed from stomach and three from esophagus. Esophageal site was associated with significant local injury, and one button battery was impacted in the esophagus, requiring rigid esophagoscopy for removal. Small battery size, used batteries, and early removal (<12 h after ingestion were associated with lesser mucosal injury. No long-term complications were noted. Our study emphasizes that early diagnosis and urgent removal of ingested button battery are the only measures which prevent complications.

    During ingestion of water, chocolate, sucrose, and saccharin, pain-related behaviors are suppressed. This ingestion analgesic effect is reversed when the hedonic valence of a food is switched from "good" to "bad" as occurs during conditioned taste aversion. Here, we tested the converse hedonic shift to determine if ingestion analgesia occurs when 0.3 M NaCl is made palatable by inducing a sodium appetite. In Experiment 1, sham- and sodium-depleted rats were tested for paw withdrawal and lick latencies to brief noxious heat during quiet wake and intraoral NaCl ingestion. Only sodium-depleted rats showed a suppression of heat-evoked reactions during NaCl ingestion. In Experiment 2, we tested whether this analgesic effect is mediated by the brainstem nucleus raphe magnus (NRM). Inactivation of NRM with muscimol blocked ingestion analgesia during NaCl ingestion by sodium-depleted rats. This attenuation was not due to a hyperalgesic effect of NRM inactivation. Muscimol microinjections into a nearby region, the nucleus raphe obscurus (NRO), were ineffective. The present findings demonstrate that the internal milieu of an animal can modify ingestion analgesia, and that the analgesia during NaCl ingestion by sodium hungry rats is mediated by NRM.

    Soil and dust ingestion by children may be important pathways of exposure to environmental contaminants. Contaminated soil and dust may end up on children's hands and objects, because they play close to the ground. These contaminants can be ingested by children, because they have a tendency to place objects, including their fingers, in their mouths. Assessing exposure through this pathway requires information about the amount of soil and dust ingested by children. Estimates of soil and dust ingestion and information on the prevalence of the behavior have been published in the literature, but research in this area is generally limited. Three methodologies have been used to quantify soil and dust ingestion rates. In this paper, these are referred to as the tracer element method, the biokinetic model comparison method, and the activity pattern method. This paper discusses the information available on the prevalence of soil and dust ingestion behavior, summarizes the three methodologies for quantifying soil and dust ingestion, and discusses their limitations. Soil ingestion data derived from studies that use these methodologies are also summarized. Although they are based on different estimation approaches, the central tendency estimates of soil and dust ingestion derived from the three methodologies are generally comparable.

    Full Text Available Chlorfenapyr has been used worldwide for agricultural pest control since 1995. Despite its widespread use, acute human poisoning data are insufficient; only a small number of fatalities from chlorfenapyr poisoning have been reported. The signs and symptoms of chlorfenapyr toxicity include nausea, vomiting, fever, rhabdomyolysis, among others. In addition, central nervous system effects in association with delayed toxicity have also been observed. Here, we detail a fatality resulting from delayed chlorfenapyr toxicity following the ingestion of a small amount of pesticide.

    This study was conducted to determine the utility of metal detection in coin localization by inexperienced operators, and determine the rate of spontaneous passage of asymptomatic esophageal coins. All children who presented to the emergency department of an urban children's hospital with a suspected coin ingestion were eligible. Coin location was predicted from metal detector results, while radiographs confirmed location. Asymptomatic patients with esophageal coins were observed for spontaneous passage. Ninety-one children (ages 9 months to 17 years) were prospectively enrolled. The metal detector had a sensitivity of 98% (53/54) in coin detection and 98% (81/83) in determining coin location as esophageal. Symptoms were poor predictors of coin location. Six of eight asymptomatic patients with esophageal coins spontaneously passed their coins. These results show that metal detection is a good screening test for coin presence and to determine coin location as esophageal. Spontaneous passage of asymptomatic esophageal coins warrants further study.

    Full Text Available Endurance exercise after orange ingestion cause anaphylaxis which is food-dependent exercise-induced anaphylaxis (FDEIA which is a form of exercise-induced anaphylaxis. In this article, an individual develops symptoms such as flushing, itching, urticaria, angioedema, and wheezing after eating a food allergen and proceeds to exercise. Neither the food alone nor exercise alone is sufficient to induce a reaction. This case report describes a 36-year-old asthmatic male athlete who experienced nausea, vomiting, flushing, urticaria, and facial swelling while exercising in a gymnasium after eating oranges. Neither oranges alone nor exercise alone induced the reaction. Total avoidance of suspected food allergens would be ideal. Persons with FDEIA should keep at hand an emergency kit with antihistamines, injectable rapid action corticoids, and adrenaline.

    The purpose of this investigation was to examine to the influence of carbohydrate ingestion (CHOI) and carbohydrate mouth rinse (CHOR) on acute repeat maximal sprint performance. Fourteen healthy males (age: 21.7 ± 1.8 years, mass: 82.3 ± 12.3 kg) completed a total of five 15-s maximal repeat sprints on a cycle ergometer against 0.075 kg ・ kg(-1) body mass each separated by 4 min of active recovery. Subjects completed four experimental trials and were randomly assigned one of four treatments: (1) CHOI, (2) CHOR, (3) placebo mouth rinse (PLAR), (4) placebo ingestion (PLAI). Subjects rinsed or ingested six 50 mL 10% CHO solutions throughout each trial. Performance variables measured included rating of perceived exertion, peak heart rate, peak and mean power output, fatigue index, and total work. Significant treatment main effects were observed for mean power output (p = 0.026), total work (p = 0.020), fatigue index (p = 0.004), and heart rate (p = 0.013). Overall mean power output and total work were significantly greater with CHOI (659.3 ± 103.0 watts, 9849.8 ± 1598.8 joules) compared with CHOR (645.8 ± 99.7 watts, 9447.5 ± 1684.9 joules, p PLAI, and PLAR. Athletes required to complete repeat bouts of high intensity exercise may benefit from CHOI.

    Amino acids play important roles in both human and animal nutrition and in the maintenance of health. Here, amino acids are classified into three groups: first, essential amino acids, which are essential to nutrition; second, functional amino acids, recently found to be important in the promotion of physiological functions; and third, dipeptides, which are used to resolve problematic features of specific free amino acids, such as their instability or insolubility. This review focusses on recent researches concerning the microbial production of essential amino acids (lysine and methionine), functional amino acids (histidine and ornithine), and a dipeptide (L-alanyl-L-glutamine).

    Mourning dove (Zenaida macroura) hunting is becoming increasingly popular, especially in managed shooting fields. Given the possible increase in the availability of lead (Pb) shot on these areas, our objective was to estimate availability and ingestion of spent shot at the Eagle Bluffs Conservation Area (EBCA, hunted with nontoxic shot) and the James A. Reed Memorial Wildlife Area (JARWA, hunted with Pb shot) in Missouri. During 1998, we collected soil samples one or 2 weeks prior to the hunting season (prehunt) and after 4 days of dove hunting (posthunt). We also collected information on number of doves harvested, number of shots fired, shotgun gauge, and shotshell size used. Dove carcasses were collected on both areas during 1998-99. At EBCA, 60 hunters deposited an estimated 64,775 pellets/ha of nontoxic shot on or around the managed field. At JARWA, approximately 1,086,275 pellets/ha of Pb shot were deposited by 728 hunters. Our posthunt estimates of spent-shot availability from soil sampling were 0 pellets/ha for EBCA and 6,342 pellets/ha for JARWA. Our findings suggest that existing soil sampling protocols may not provide accurate estimates of spent-shot availability in managed dove shooting fields. During 1998-99, 15 of 310 (4.8%) mourning doves collected from EBCA had ingested nontoxic shot. Of those doves, 6 (40.0%) contained a?Y7 shot pellets. In comparison, only 2 of 574 (0.3%) doves collected from JARWA had ingested Pb shot. Because a greater proportion of doves ingested multiple steel pellets compared to Pb pellets, we suggest that doves feeding in fields hunted with Pb shot may succumb to acute Pb toxicosis and thus become unavailable to harvest, resulting in an underestimate of ingestion rates. Although further research is needed to test this hypothesis, our findings may partially explain why previous studies have shown few doves with ingested Pb shot despite their feeding on areas with high Pb shot availability.

    The purpose of this study was to determine if the ingestion of sodium citrate (CIT) alters blood levels of fluid and electrolyte regulatory hormones at rest and during exercise. Using a randomized, double-blinded, crossover design, 13 young, male well-trained runners performed continuous incremental running tests to volitional exhaustion on a treadmill 2 h after ingestion of 0.5 g.kg-1 body mass of CIT or placebo (PLC) in 1000 mL of solution. These trials were separated by 2 weeks. Baseline (before ingestion) aldosterone concentration did not differ between the 2 trials; however, it was 36.5% (p = 0.003) lower in the CIT trial compared with the PLC trial before the running test (i.e., after ingestion). The extent of the running-induced increase in aldosterone was 33% (p = 0.009) smaller in the CIT trial. There were no between-trial differences in the levels of adrenocorticotropic hormone, N-terminal pro-B-type natriuretic peptide, or renin activity at any stage of the study. However, a greater relative increase in plasma volume (mean +/- SD, 6.41% +/- 3.78% vs. 4.08% +/- 3.33%; p = 0.042) was observed after administering the CIT compared with the PLC drink. Serum Na+ concentration increased (by 3.1 +/- 1.2 mmol.L-1; p < 0.0001) after ingestion of the CIT but not the PLC drink. A higher Na+ level was observed in the CIT trial than in the PLC trial (142.4 +/- 1.6 vs. 139.3 +/- 1.4 mmol.L-1, p = 0.00001) after completion of the run. In conclusion, pre-exercise ingestion of CIT induces a decrease in serum aldosterone concentration in the resting condition and a blunting of the aldosterone response during incremental running exercise to volitional exhaustion. The observed effect of CIT on the serum aldosterone level may be mediated by an acute increase in plasma volume and serum Na+ concentration alterations.

    2004-01-01

    Full Text Available CONTEXT: Carbamate insecticides are widely used in commercial agriculture and home gardening. A serious side effect of organophosphate and carbamate intoxication is the development of acute pancreatitis. CASE REPORT: A 36-year-old Caucasian woman was admitted to our hospital with cholinergic crisis and pancreatitis soon after the ingestion of a carbamate insecticide (carbofuran. An abdominal CT scan disclosed pancreatic necrosis with intrapancreatic fluid collection, consistent with the development of a pancreatic pseudocyst in a subsequent CT scan. No predisposing factor for pancreatitis was evident. Pseudocholinesterase levels returned to normal 7 days later and the patient was discharged in good physical condition one month after admission. DISCUSSION: Although acute pancreatitis is not infrequent after organophosphate intoxication, it is quite rare after carbamate ingestion and has not been previously reported after carbofuran intoxication.

    2015-12-15

    The digestive tract contents of 263 individuals from 26 species of commercial fish were examined for microplastics. These were found in 17 species, corresponding to 19.8% of the fish of which 32.7% had ingested more than one microplastic. Of all the fish that ingested microplastics, 63.5% was benthic and 36.5% pelagic species. A total of 73 microplastics were recorded, 48 (65.8%) being fibres and 25 (34.2%) being fragments. Polymers were polypropylene, polyethylene, alkyd resin, rayon, polyester, nylon and acrylic. The mean of ingested microplastics was 0.27 ± 0.63 per fish, (n=263). Pelagic fish ingested more particles and benthic fish ingested more fibres, but no significant differences were found. Fish with the highest number of microplastics were from the mouth of the Tagus river. Scomber japonicus registered the highest mean of ingested microplastics, suggesting its potential as indicator species to monitor and investigate trends in ingested litter, in the MSFD marine regions.

    2014-01-01

    There is increasing concern about the impacts of microplastics (marine biota. Microplastics may be mistaken for food items and ingested by a wide variety of organisms. While the effects of ingesting microplastic have been explored for some adult organisms, there is poor understanding of the effects of microplastic ingestion on marine larvae. Here, we investigated the ingestion of polyethylene microspheres by larvae of the sea urchin, Tripneustes gratilla. Ingestion rates scaled with the concentration of microspheres. Ingestion rates were, however, reduced by biological fouling of microplastic and in the presence of phytoplankton food. T. gratilla larvae were able to egest microspheres from their stomach within hours of ingestion. A microsphere concentration far exceeding those recorded in the marine environment had a small nondose dependent effect on larval growth, but there was no significant effect on survival. In contrast, environmentally realistic concentrations appeared to have little effect. Overall, these results suggest that current levels of microplastic pollution in the oceans only pose a limited threat to T. gratilla and other marine invertebrate larvae, but further research is required on a broad range of species, trophic levels, and polymer types.

    Overconsumption of sugar-sweetened beverages has been implicated in the pathogenesis of CVD. The objective of the present study was to elucidate acute haemodynamic and microcirculatory responses to the ingestion of sugary drinks made from sucrose, glucose or fructose at concentrations similar to those often found in commercial soft drinks. In a randomised cross-over study design, twelve young healthy human subjects (seven men) ingested 500 ml tap water in which was dissolved 60 g of either sucrose, glucose or fructose, or an amount of fructose equivalent to that present in sucrose (i.e. 30 g fructose). Continuous cardiovascular monitoring was performed for 30 min before and at 60 min after ingestion of sugary drinks, and measurements included beat-to-beat blood pressure (BP) and impedance cardiography. Additionally, microvascular endothelial function testing was performed after iontophoresis of acetylcholine and sodium nitroprusside using laser Doppler flowmetry. Ingestion of fructose (60 or 30 g) increased diastolic and mean BP to a greater extent than the ingestion of 60 g of either glucose or sucrose (Psugary drinks. In conclusion, ingestion of fructose, but not sucrose, increases BP in healthy human subjects. Although sucrose comprises glucose and fructose, its changes in TPR and CO are more related to glucose than to fructose.

    1989-09-01

    After ingesting or inhaling laundry detergent powder, eight children required hospital admission. The predominant symptoms were stridor, drooling, and respiratory distress. All but one patient underwent endoscopy of the airways and the esophagus, five children were admitted to the intensive care unit, and four children required endotracheal intubation. Laundry detergent ingestions are generally considered to have minor consequences, and there exists a paucity of literature on the subject. Evidence of significant morbidity incurred because of ingestion or inhalation of sodium carbonate-containing laundry detergent powder is presented, together with a review of the existing literature.

    2010-01-01

    Boxing is a sport that consists of multiple high-intensity bouts separated by minimal recovery time and may benefit from a pre-exercise alkalotic state. The purpose of this study was to observe the ergogenic potential of sodium bicarbonate (NaHCO3) ingestion on boxing performance. Ten amateur boxers volunteered to participate in 2 competitive sparring bouts. The boxers were prematched for weight and boxing ability and consumed either 0.3 g.kg(-1) body weight (BW) of NaHCO3 (BICARB) or 0.045 g.kg(-1) BW of NaCl placebo (PLAC) mixed in diluted low calorie-flavored cordial. The sparring bouts consisted of four 3-minute rounds, each separated by 1-minute seated recovery. Blood acid-base (pH, bicarbonate [HCO3(-)], base excess [BE]), and performance (rates of perceived exertion [RPE], heart rate [HR] [HR(ave) and HR(max)], total punches landed successfully) profiles were analyzed before (where applicable) and after sparring. The results indicated a significant interaction effect for HCO3(-) (p < or = 0.001) and BE (p < 0.001), but not for pH (p = 0.48). Post hoc analysis revealed higher presparring HCO3(-) and BE for the BICARB condition, but no differences between the BICARB and PLAC conditions postsparring. There was a significant increase in punches landed during the BICARB condition (p < 0.001); however, no significant interaction effects for HRave (p = 0.15), HRmax (p = 0.32), or RPE (p = 0.38). The metabolic alkalosis induced by the NaHCO3 loading elevated before and after sparring blood buffering capacity. In practical application, the findings suggest that a standard NaHCO3 loading dose (0.3 g.kg(-1)) improves punch efficacy during 4 rounds of sparring performance.

    2016-12-01

    The ghost pepper, or "bhut jolokia," is one of the hottest chili peppers in the world. Ghost peppers have a measured "heat" of > 1,000,000 Scoville heat units (SHU), more than twice the strength of a habanero pepper. To our knowledge, no significant adverse effects of ghost pepper ingestion have been reported. A 47-year-old man presented to the Emergency Department (ED) with severe abdominal and chest pain subsequent to violent retching and vomiting after eating ghost peppers as part of a contest. A subsequent chest x-ray study showed evidence of a left-sided pleural effusion and patchy infiltrates. A computed tomography scan of the abdomen and pelvis showed pneumomediastinum with air around the distal esophagus, suggestive of a spontaneous esophageal perforation and a left-sided pneumothorax. The patient was intubated and taken immediately to the operating room, where he was noted to have a 2.5-cm tear in the distal esophagus, with a mediastinal fluid collection including food debris, as well as a left-sided pneumothorax. The patient was extubated on hospital day 14, and was discharged home with a gastric tube in place on hospital day 23. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Spontaneous esophageal rupture, Boerhaave syndrome, is a rare condition encountered by emergency physicians, with a high mortality rate. This case serves as an important reminder of a potentially life- threatening surgical emergency initially interpreted as discomfort after a large spicy meal. Copyright © 2016 Elsevier Inc.

    Experiments were carried out with different Baltic Sea zooplankton taxa to scan their potential to ingest plastics. Mysid shrimps, copepods, cladocerans, rotifers, polychaete larvae and ciliates were exposed to 10 μm fluorescent polystyrene microspheres. These experiments showed ingestion of microspheres in all taxa studied. The highest percentage of individuals with ingested spheres was found in pelagic polychaete larvae, Marenzelleria spp. Experiments with the copepod Eurytemora affinis and the mysid shrimp Neomysis integer showed egestion of microspheres within 12 h. Food web transfer experiments were done by offering zooplankton labelled with ingested microspheres to mysid shrimps. Microscopy observations of mysid intestine showed the presence of zooplankton prey and microspheres after 3 h incubation. This study shows for the first time the potential of plastic microparticle transfer via planktonic organisms from one trophic level (mesozooplankton) to a higher level (macrozooplankton). The impacts of plastic transfer and possible accumulation in the food web need further investigations.

    2009-03-01

    This report describes a 5-week-old female infant who presented with accidental ingestion of rubbing alcohol (which contains about 70% isopropanol), and was subsequently diagnosed with cerebral sinovenous thrombosis. Isopropanol is a clear, volatile 3-carbon alcohol found in varying concentrations in many solvents. Mislabeled rubbing alcohol was mixed with this patient's formula. After ingesting it, she presented with a 1-day history of uncontrolled fussiness and an episode of deviation of the eyes to the right for 30 minutes, followed by rhythmic movements of the arms and legs for 20 minutes. Cerebral imaging demonstrated sinovenous thrombosis. To our knowledge, there have been no reports describing cerebral sinovenous thrombosis as a complication of isopropanol ingestion. The possible association of isopropanol ingestion and sinovenous thrombosis is discussed.

    We present two diagnostically challenging cases of acute pancreatitis with hypertriglyceridemia accompanied with chylomicronemia caused with a deficiency of lipoprotein lipase and with the presence of type V hyperlipidemia.Both cases suffered from acute abdomen following the ingestion of fatty food and revealed the increase in parameters of inflammation without significant elevation of serum amylase levels. The imaging examination of ultrasonography could not detect significant findings of acute pancreatitis and a computer tomography scan eventually confirmed the findings of acute pancreatitis. Both cases responded to a low fat diet and administration of a cholecystokinin receptor antagonist, exhibiting a relief of abdominal symptoms. As in the present cases with acute abdomen following the ingestion of fatty food, the identification of serum hypertriglyceridemia and an abdominal computer tomography scan might be useful in establishing the diagnosis of acute pancreatitis and in developing the therapeutic regimen, when hypertriglyceridemia interferes with the evaluation of pancreatic enzyme activities and ultrasound examination provides poor pancreatic visualization.

    This study examined the acute effects of NaHCO3 ingestion on repetitions to failure and rating of perceived exertion in the back squat and bench press in trained men. Eight resistance-trained men took part in this double-blind, randomized crossover experimental study whereby they ingested NaHCO3 (0.3 g·kg(-1) body mass) or placebo (sodium chloride NaCl: 0.045 g·kg(-1) body mass) solution 60 minutes before completing a bout of resistance exercise (3 sets of bench press and back squat exercise to failure at an intensity of 80% 1 repetition maximum). Experimental conditions were separated by at least 48 hours. Participants completed more repetitions to failure in the back squat after NaHCO3 ingestion (p = 0.04) but not for bench press (p = 0.679). Mean ± SD of total repetitions was 31.3 ± 15.3 and 24.6 ± 16.2 for back squat and 28.7 ± 12.2 and 26.7 ± 10.2 for bench press in NaHCO3 and placebo conditions, respectively. Repetitions to failure decreased as set increased for the back squat and bench press (p = 0.001, both). Rating of perceived exertion significantly increased with set for the back squat and bench press (p = 0.002, both). There was no significant change in blood lactate across time or between conditions. There were however treatment × time interactions for blood pH (p = 0.014) and blood HCO3 concentration (p = 0.001). After ingestion, blood pH and HCO3 (p = 0.008) concentrations were greater for the NaHCO3 condition compared with the placebo condition (p < 0.001). The results of this study suggest that sodium bicarbonate ingestion can enhance resistance exercise performance using a repetition to failure protocol in the first exercise in a resistance exercise session.

    BACKGROUND The purpose of this study was to evaluate the characteristics, management, and outcomes of disc battery ingestion in children. METHODS We reviewed the medical records of children admitted to Mofid Children's Hospital due to disc battery ingestion from January 2006 to January 2010. Clear history, clinical symptoms and results of imaging studies revealed diagnosis of disc battery ingestion in suspected patients. The clinical data reviewed included age, gender, clinical manifestation, radiologic findings, location of disc battery, duration of ingestion, endoscopic results and surgical treatment. RESULTS We found 22 cases (11 males and 11 females) of disc battery ingestion with a mean age of 4.3 years (range: 9 months to 12 years). Common symptoms were vomiting, cough, dysphagia, and dyspnea. The mean duration of ingestion was 2.7 days (4 hours to 1.5 months). A total of 19 patients had histories of disc battery ingestion, but three cases referred with the above symptoms, and the batteries were accidentally found by x-ray. Only three cases had batteries impacted in the esophagus. Twelve batteries were removed endoscopically, 6 batteries spontaneously passed through the gastrointestinal (GI) tract within 5 to 7 days, and 4 patients underwent surgery due to complications: 3 due to tracheo-esophageal fistula (TEF) and 1 due to intestinal perforation. There was no mortality in our study. CONCLUSION Most cases of disc battery ingestion run uneventful courses, but some may be complicated. If the battery lodges in the esophagus, emergency endoscopic management is necessary. However, once in the stomach, it will usually pass through the GI tract.

    Foreign body ingestion is a frequent emergency occurrence. Serious complications, although rare, include pharyngooesophageal perforation, aorto-oesophageal fistula and deep neck infection. A retrospective review was performed of all cases of foreign body ingestion requiring hospitalization between 1989 and 2011, in a tertiary Hospital. Cases complicated by deep cervical abscess were selected and their clinical presentation, results of diagnostic exams, therapeutics and clinical evolution are presented. Among a total of 1679 cases, 319 were related to pediatric patients and 1360 to adults. Two cases were reported (0.12%): an adult, 41 years-old, with parapharyngeal abscess subsequent to fishbone ingestion, and a child, 13 months-old, with retropharyngeal abscess consequent to chicken bone ingestion. Complications appeared three and four days after foreign body removal, respectively. In both situations cervical computerized tomography scan with contrast and surgical drainage were accomplished; the child was also submitted to rigid esophagoscopy for residual foreign body removal and closure of the associated pharyngeal laceration. Deep cervical abscesses are an uncommon but possible complication of foreign body ingestion and constitute a diagnostic challenge, particularly in children. Previous oesophageal manipulation by flexible endoscopy may be considered a risk factor for such complication. Imagiological studies proved to be crucial for diagnosis and therapeutic planning. Although a rare complication, given a recent history of foreign body ingestion/removal and the presence of compatible symptoms, cervical abscesses should be taken into account, highlighting their potential morbimortality in the absence of an appropriate therapeutic approach.

    To describe the clinical presentations and management of detergent pod ingestion at a tertiary children's hospital. Case series. A retrospective chart review of children diagnosed with detergent pod ingestion from June 2010 and March 2015. Nine cases of detergent pod ingestion were included over a 5-year period. The average age was 26.3 months (range, 11-43 months). Eight (89%) of the cases were female. The patients had ingested laundry detergent pods (n = 7) and dishwasher detergent pods (n = 2). The majority of patients (67%) had more than one clinical manifestation from ingestion. Presenting symptoms included emesis (78%), respiratory symptoms (56%), throat pain (22%), drooling (33%), and foaming at the mouth (33%). The management of patients depended on the severity of their symptoms and included admission to an overnight observation unit (n = 5), discharge to home directly from the emergency department (n = 2), and admission to the hospital (n = 2). Two (22%) children underwent esophagogastroduodenoscopy. One child (11%) required intubation from bilateral vocal fold immobility. Injuries to the upper aerodigestive tract after detergent ingestion range from mild gastrointestinal symptoms to respiratory compromise. The majority of children improve with observation alone; however, clinicians should maintain a low threshold for endoscopic evaluation in cases of severe symptoms and airway involvement. 4.

    Ingestion of marine debris can have lethal and sublethal effects on sea turtles and other wildlife. Although researchers have reported on ingestion of anthropogenic debris by marine turtles and implied incidences of debris ingestion have increased over time, there has not been a global synthesis of the phenomenon since 1985. Thus, we analyzed 37 studies published from 1985 to 2012 that report on data collected from before 1900 through 2011. Specifically, we investigated whether ingestion prevalence has changed over time, what types of debris are most commonly ingested, the geographic distribution of debris ingestion by marine turtles relative to global debris distribution, and which species and life-history stages are most likely to ingest debris. The probability of green (Chelonia mydas) and leatherback turtles (Dermochelys coriacea) ingesting debris increased significantly over time, and plastic was the most commonly ingested debris. Turtles in nearly all regions studied ingest debris, but the probability of ingestion was not related to modeled debris densities. Furthermore, smaller, oceanic-stage turtles were more likely to ingest debris than coastal foragers, whereas carnivorous species were less likely to ingest debris than herbivores or gelatinovores. Our results indicate oceanic leatherback turtles and green turtles are at the greatest risk of both lethal and sublethal effects from ingested marine debris. To reduce this risk, anthropogenic debris must be managed at a global level. Análisis Global de la Ingesta de Residuos Antropogénicos por Tortugas Marinas La ingesta de residuos marinos puede tener efectos letales y subletales sobre las tortugas marinas y otros animales. Aunque hay investigadores que han reportado la ingesta de residuos antropogénicos por tortugas marinas y la incidencia de la ingesta de residuos ha incrementado con el tiempo, no ha habido una síntesis global del fenómeno desde 1985.

    Full Text Available Abstract Background We have recently demonstrated that consuming a thermogenic drink (TD acutely increases energy expenditure and serum markers of lipolysis in healthy, college-aged individuals. The purpose of this study was to determine if consuming TD over 28 days affects its acute thermogenic and lipolytic effects as well as body composition and clinical chemistry safety markers. Methods Sixty healthy, males (mean ± SE; 23 ± 1 years, 177 ± 2 cm, 81.7 ± 2.1 kg, 22.8 ± 1.4% body fat; n = 30 and females (23 ± 1 years, 166 ± 2 cm, 62.1 ± 1.8 kg, 28.3 ± 1.4% body fat; n = 30 reported to the laboratory on day 0 (T1 for determination of body composition, resting energy expenditure (REE as well as glycerol and free fatty acid (FFA levels before and after ingesting either 336 ml of TD or a non-caloric, non-caffeinated placebo (PLA drink. Following day 0, participants supplemented daily with 336 ml·day-1 of either TD or PLA and repeated identical testing procedures on day 28 (T2. Day 28 area under the curve (AUC values were calculated for REE, FFA, and glycerol. Day 28 acute data and prolonged AUC comparisons between groups were analyzed using ANOVAs with repeated measures. Results Percent body fat (p = 0.02 and fat mass (p = 0.01 decreased in the TD group compared to the PLA group after 28 days. Day 28 FFA AUC values (p = 0.048 were greater in the TD group compared to the PLA group. There was no significant difference in day 28 REE AUC values (p = 0.30 or glycerol AUC values (p = 0.21, although a significant increase in REE values in the PLA group may have confounded these findings. There were no differences between groups concerning blood and clinical safety markers. Conclusion Within-group elevations in FFA and REE values in the TD group were still evident following a 28-day supplementation period which may contribute to the observed decrements in %BF. Further, prolonged TD supplementation did not alter the assessed clinical safety markers

    Foreign body (FB) ingestion is an uncommon reason for going to the Paediatric Emergency Department (PED). The aim of this study was to assess the clinical and epidemiological characteristics of foreign body ingestion and the management of these patients. Retrospective study, including children under 14 years old with suspected foreign body ingestion seen in the PED between 2010 and 2013. An analysis was made of the circumstances of the FB ingestion, its management in the PED, and patient outcomes. Of the 226,666 presentations recorded, 1,608 (0.7%) were for a FB, 970 corresponding to ingestion of mainly fish bones (367, 38.7%) and coins (181, 18.7%), except in children under 1 year (plastic objects). The median age was 4.7 years, with boys being more common in those older than 4 years (58.5%). A total of 557 patients (57.3%) reported some symptom, and complementary tests were performed in 414 (42.7%). Another specialist was called in 315 (32.4%) cases, mainly from Ear, Nose and Throat (fish bones) or Surgery (coins). The FB was removed in 305 (31.4%) cases, which were mostly fish bones or sunflower seeds. Seventy-one patients (7.3%) were admitted, especially ingestion of fish bones or coins. No patient died. Ingestion of fish bones or coins by young children is a relatively common presentation in the PED, and it is associated with frequent medical interventions. Although the overall prognosis is good, and improving the health education of the population should be considered to reduce the frequency of these episodes.

    Tramadol can cause life-threatening toxicity in overdose; however, data on its toxicity in children are lacking. This study investigates toxicity associated with tramadol ingestions in children. The hypothesis is that children will experience dose-related central nervous system and respiratory depression and seizures. A retrospective evaluation of cases from the National Poison Center Data System between January 1, 2000, and December 31, 2013, was performed. Inclusion criteria were age below 6 years and single-substance acute tramadol ingestion. For dose-effect analysis, cases with sufficient dose quantity information were included. There were 7334 cases that met inclusion criteria. Outcomes were 84.8% no effect, 12.6% minor, 2.2% moderate, and 0.4% major effect. There was 1 fatality. Most of the children (36.4%) were treated/released from the emergency department; other management sites were home (36.4%), admission (5.9%), and others (3.2%). In the 1115 children with symptoms, drowsiness (N = 611) and vomiting (N = 178) occurred most frequently. More serious clinical effects included respiratory depression in 36 and seizures in 24 children. Of 2772 children with milligram dose recorded, there were 10 cases of respiratory depression and 6 of seizure. Median doses for respiratory depression and seizure were 225 (range, 50-600 mg) and 525 mg (range, 50-1050 mg), respectively. The minimum weight-based dose for respiratory depression/arrest was 7.9 mg/kg and for seizures, 4.8 mg/kg. Seizure and respiratory depression are uncommon in pediatric tramadol ingestions. Given the small number of patients with dose data and lack of laboratory confirmation of dose, more studies are needed to determine the minimum dose at which medical management is recommended.

    To characterize clinical signs, diagnostic test results, foreign body location, treatment, and outcome for dogs and cats with sewing needle foreign bodies. Retrospective case series. 65 dogs and cats with sewing needle foreign bodies. Medical records of 27 dogs and 38 cats examined because of sewing needle foreign bodies from January 2000 to February 2012 were reviewed for signalment, medical history, physical examination findings, diagnostic test results, interval from witnessed exposure and radiographic imaging to definitive treatment, definitive treatment, sewing needle location, complications, and outcome. 7 (10.8%) animals had sewing needles in extragastrointestinal locations that were not causing clinical signs. The remaining 58 (89.2%) animals had known sewing needle exposure or acute clinical signs associated with ingestion. The esophageal and gastric regions were the most common location for a sewing needle (10/21 [47.6%] dogs; 19/37 [51.4%] cats), followed by the oropharynx (7/21 [33.3%] dogs; 11/37 [29.7%] cats) and small and large intestines (4/21 [19.0%] dogs; 7/37 [18.9%] cats). Gastrointestinal perforation was detected in 10 of 58 (17.2%) animals (5/21 [23.8%] dogs; 5/37 [13.5%] cats). Sewing needles in the esophagus and stomach were successfully removed endoscopically in 8 of 9 dogs and 18 of 19 cats. Survival rate was 98.1% (51/52) for animals receiving definitive treatment. Endoscopic removal of ingested sewing needles was highly successful and should be recommended to prevent gastrointestinal tract perforation and associated morbidity. Prognosis for dogs and cats receiving definitive treatment for sewing needle foreign body ingestion was excellent.

    The study purpose was to determine the ability of hand-held metal detectors (HHMDs) to identify the presence of ingested metallic foreign bodies (MFBs). Twenty-three children presenting to the emergency department with a complaint of MFBs ingested were enrolled. Sixteen of 23 patients had radiographically proven foreign bodies. The MFBs comprised coins (n = 11), a button battery (n = 1), a medallion (n = 1), a token (n = 1), a needle (n = 1), and a marble (leaded glass) (n = 1). The HHMD correctly detected 15 of 16 radiographically positive MFBs (93%) and correctly excluded a potential MFB in six of six radiographically negative cases. The only foreign body not detected was an ingested needle. One radiograph was equivocal. Radiographic localization of the ingested objects was as follows: esophagus, n = 4; stomach, n = 9; and intestines, n = 3. The HHMD correctly localized all detected MFBs. The HHMD had a sensitivity of 94%, a specificity of 100%, a positive predictive value of 100%, and a negative predictive value of 86%. HHMDs are effective screening devices for possible ingested MFBs. Positive studies localized to the stomach and lower gastrointestinal tract do not require confirmatory radiographic studies.

    To describe patterns and severity of caustic injuries sustained from dishwasher powder ingestion and highlight need for national safety standards. Retrospective chart review of admissions for caustic ingestion to Starship Children's Hospital from January 2003 to January 2005 and review of New Zealand National Poisons Centre data. Between January 2003 and January 2005, the National Poisons Centre recorded 610 dishwashing powder ingestions, with 88% of children less than 2 years old. Twenty-three children were admitted to Starship Children's Hospital following caustic ingestion, of whom 11 were identified as having ingested dishwasher powder (9 boys and 2 girls) and were aged 11 to 30 months (mean 17.5). Five children (45%) were admitted to the Paediatric Intensive Care Unit over 4 months (October 2004 to January 2005), requiring intubation for airway control. Two children needed tracheostomy. Three of the 11 children (27%) required repeated oesophageal dilatation, and two underwent gastrostomy formation. One brand of dishwasher detergent and container type was implicated in over half of the cases. Dishwasher detergents are highly corrosive substances that cause potentially life-threatening injuries and ongoing morbidity. The recent surge of incidents may be related to change in product constituents or non-compliance with New Zealand safety standards. Efforts to limit product alkalinity, legislative requirement of Child-Resistant Packaging and public education may reduce injuries from these common household substances.

    Full Text Available We report a case of fulminant liver failure resulting in emergent liver transplantation following 3 weeks of nausea, vomiting, and malaise from Jamaican Vomiting Sickness. Jamaican Vomiting Sickness is caused by ingestion of the unripe arils of the Ackee fruit, its seeds and husks. It is characterized by acute gastrointestinal illness and hypoglycemia. In severe cases, central nervous system depression can occur. In previous studies, histologic sections taken from patients with Jamaican Vomiting Sickness have shown hepatotoxicity similar to that seen in Reye syndrome and/or acetaminophen toxicity. We highlight macroscopic and microscopic changes in the liver secondary to hepatoxicity of Ackee fruit versus those caused by a previously unknown sickle cell trait. We discuss the clinical variables and the synergistic hepatotoxic effect of Ackee fruit and ischemic injury from sickled red blood cells, causing massive hepatic necrosis in this patient.

    Argyria is a rare cutaneous discoloration caused by the intake of silver or various compounds containing silver. We report a case of argyria in a 73-year-old male following ingestion of colloidal silver as an alternative medicine over 5 years. He had a diffuse, slate gray discoloration of his face and hands. A biopsy specimen from the face revealed brown-black extracellular granules in the upper dermis and between collagen bundles. We also found silver particles in the mucous of the colon. The ingestion of colloidal silver appears to be increasing among patients using alternative health practices. We report this case to bring people's attention to the problems associated with the ingestion of colloidal silver.

    Microplastics pollution is widespread in marine ecosystems and a major threat to biodiversity. Nevertheless, our knowledge of the impacts of microplastics in freshwater environments and biota is still very limited. The interaction of microplastics with freshwater organisms and the risks associated with the human consumption of organisms that ingested microplastics remain major knowledge gaps. In this study, we assessed the ingestion of microplastics by Hoplosternum littorale, a common freshwater fish heavily consumed by humans in semi-arid regions of South America. We assessed the abundance and diversity of both plastic debris and other food items found in the gut of fishes caught by local fishermen. We observed that 83% of the fish had plastic debris inside the gut, the highest frequency reported for a fish species so far. Most of the plastic debris (88.6%) recovered from the guts of fish were microplastics (microplastics at the urbanized sections of the river, and that the ingestion of microplastics was negatively correlated with the diversity of other food items in the gut of individual fish. Nevertheless, microplastics ingestion appears to have a limited impact on H. littorale, and the consequences of human consumption of this fish were not assessed. Our results suggest freshwater biota are vulnerable to microplastics pollution and that urbanization is a major factor contributing to the pollution of freshwater environments with microplastics. We suggest the gut content of fish could be used as a tool for the qualitative assessment of microplastics pollution in freshwater ecosystems. Further research is needed to determine the processes responsible for the high incidence of microplastics ingestion by H. littorale, and to evaluate the risk posed to humans by the consumption of freshwater fish that ingested microplastics.

    This study assessed the percentage of the amount of dentifrice loaded onto the toothbrush that is ingested by children, taking into account age, the amount of dentifrice used during toothbrushing, and the dentifrice flavor. The sample consisted of 155 children of both genders attending public kindergartens and schools in Bauru, Brazil, divided into 5 groups (n = 30-32) of children aged 2, 3, 4, 5 and 6 years old. The dentifrices used were Sorriso™ (1219 ppm F, peppermint-flavored) and Tandy™ (959 ppm F, tutti-frutti-flavored). The assessment of fluoride intake from dentifrices was carried out six times for each child, using 0.3, 0.6, and 1.2 g of each dentifrice, following a random, crossover distribution. Brushing was performed by the children or their parents/caregivers according to the home habits and under the observation of the examiner. Fluoride present in the expectorant and on toothbrush was analyzed with an ion-specific electrode after HMDS-facilitated diffusion. Fluoride ingestion was indirectly derived. Results were analyzed by 3-way repeated-measures anova and Tukey's tests (P dentifrice ingested as response variable. Age and percent dentifrice ingested for both dentifrices, and the three amounts used were inversely related (P dentifrice ingested was significantly higher after the use of Tandy™ under all conditions of the study when compared with Sorriso™ (P dentifrices tested (P < 0.05). The results indicate that all variables tested must be considered in preventive measures aiming to reduce the amount of fluoride ingested by young children. © 2011 John Wiley & Sons A/S.

    Collier, NB, Hardy, MA, Millard-Stafford, ML, and Warren, GL. Small beneficial effect of caffeinated energy drink ingestion on strength. J Strength Cond Res 30(7): 1862-1870, 2016-Because caffeine ingestion has been found to increase muscle strength, our aim was to determine whether caffeine when combined with other potential ergogenic ingredients, such as those in commercial energy drinks, would have a similar effect. Fifteen young healthy subjects were used in a double-blind, repeated-measures experimental design. Each subject performed 3 trials, ingesting either a caffeinated energy drink, an uncaffeinated version of the drink, or a placebo drink. The interpolated twitch procedure was used to assess maximum voluntary isometric contraction (MVIC) strength, electrically evoked strength, and percent muscle activation during MVIC of the knee extensors both before and after drink ingestion, and after a fatiguing bout of contractions; electromyographic (EMG) amplitude of the knee extensors during MVIC was also assessed. The mean (±SE) change in MVIC strength from before to after drink ingestion was significantly greater for the caffeinated energy drink compared with placebo [+5.0 (±1.7) vs. -0.5 (±1.5)%] and the difference between the drinks remained after fatigue (p = 0.015); the strength changes for the uncaffeinated energy drink were not significantly different from those of the other 2 drinks at any time. There was no significant effect of drink type on the changes in electrically evoked strength, percent muscle activation, and EMG from before to after drink ingestion. This study indicates that a caffeinated energy drink can increase MVIC strength but the effect is modest and the strength increase cannot be attributed to increased muscle activation. Whether the efficacy of energy drinks can be attributed solely to caffeine remains unclear.

    The beneficial effects of caffeine on aerobic activity and resistance training performance are well documented. However, less is known concerning caffeine's potential role in reducing perception of pain and soreness during exercise. In addition, there is no information regarding the effects of caffeine on delayed onset muscle soreness (DOMS). The primary purpose of this study was to examine the effect of caffeine ingestion on muscle soreness, blood enzyme activity, and performance after a bout of elbow flexion/extension exercise. Nine low-caffeine-consuming males (body mass: 76.68 ± 8.13 kg; height: 179.18 ± 9.35 cm; age: 20 ± 1 year) were randomly assigned to ingest either caffeine or placebo 1 hour before completing 4 sets of 10 bicep curls on a preacher bench, followed by a fifth set in which subjects completed as many repetitions as possible. Soreness and soreness on palpation intensity were measured using three 0-10 visual analog scales before exercise, and 24, 48, 72, 96, and 120 hours after exercise. After a washout period, subjects crossed over to the other treatment group. Caffeine ingestion resulted in significantly (p ≤ 0.05) lower levels of soreness on day 2 and day 3 compared with placebo. Total repetitions in the final set of exercise increased with caffeine ingestion compared with placebo. This study demonstrates that caffeine ingestion immediately before an upper-body resistance training out enhances performance. A further beneficial effect of sustained caffeine ingestion in the days after the exercise bout is an attenuation of DOMS. This decreased perception of soreness in the days after a strenuous resistance training workout may allow individuals to increase the number of training sessions in a given time period.

    This work examined the influence of an acute dose of sodium bicarbonate (NaHCO3) on buffering capacity and performance during a repeated sprint ability (RSA) protocol. Eleven (mean ± SD: age 24.6 ± 6.1 years; mass 74.9 ± 5.7 kg; height 177.2 ± 6.7 cm) participated in the study, undertaking 4 test sessions. On the first visit to the laboratory, each participant ingested 300 mg · kg(-1) of NaHCO3 (in 450 ml of flavored water) and blood samples were obtained at regular intervals to determine the individual times peak pH and HCO3. In subsequent visits, participants ingested 300 mg · kg(-1) of NaHCO3, 270 mg · kg(-1) body mass (BM) of NaCI, or no drink followed by a RSA cycling protocol (10 × 6 seconds sprints with 60 seconds recovery), which commenced at each individuals predetermined ingestion peak pH response time. Blood samples were obtained before exercise and after the first, fifth, and 10th sprint to determine the blood pH, HCO3, and lactate (La) responses. Total work completed during the repeated sprint protocol was higher (p ≤ 0.05) in the NaHCO3 condition (69.8 ± 11.7 kJ) compared with both the control (59.6 ± 12.2 kJ) and placebo (63.0 ± 8.3 kJ) conditions. Peak power output was similar (p > 0.05) between the 3 conditions. Relative to the control and placebo conditions, NaHCO3 ingestion induced higher (p ≤ 0.05) blood pH and HCO3 concentrations before exercise and during the bouts, and higher lactate concentrations (p ≤ 0.05) after the final sprint. Results suggest that NaHCO3 improves the total amount of work completed during RSA through enhanced buffering capacity.

    Dose estimation was conducted for internal phosphorus-32 exposure in one young male subject from repeated oral mis-ingestion for >1 year. Since disclosure for previous continuous contamination, a series of urine samples were collected from this individual weekly for a period of >2 months. P-32 radioactivity in urine samples were measured by the acid precipitation method. Estimation for retrospective total effective dose equivalent received by this subject was conducted for cumulative internal dose estimation. A minimum of 9.4 mSv was estimated for an assumed single ingestion. As this was a rare case in radiation protection and internal radiation dosimetry, its implications were of considerable significance.

    Liver abscess is a cause of febrile abdominal pain and usually the origin of a liver abscess is ascending cholangitis, hemathological diffusion, via the portal vein or the hepatic artery, or superinfection of necrotic tissue. Solitary pyogenic abscess with no obvious systemic cause may be secondary to a local event such as the migration of an ingested foreign body. We report the case of a solitary liver abscess caused by an ingested foreign body, a fish bone, migrated through the gastric wall into the left lobe. PMID:26017106

    Full Text Available Mushroom-related poisoning can cause acute kidney injury. Here we report a case of acute kidney injury after ingestion of Amanita punctata, which is considered an edible mushroom. Gastrointestinal symptoms occurred within 24 hours from the mushroom intake and were followed by an asymptomatic period, acute kidney injury, and elevation of liver and pancreatic enzymes. Kidney function recovered with supportive care. Nephrotoxic mushroom poisoning should be considered as a cause of acute kidney injury.

  8. Health Risk Evaluations for Ingestion Exposure of Humans to Polonium-210

    The incident in London during November 2006 involving a lethal intake by Mr. Alexander Litvinenko of the highly-radioactive, alpha-particles-emitting polonium-210 (Po-210) isotope, presumably via ingestion, sparked renewed interest in the area of Po-210 toxicity to humans. This paper is the result of assembling and interpreting existing Po-210 data within the context of what is considered a reliable risk model (hazard-function [HF] model) for characterizing the risk of death from deterministic effects of high alpha radiation doses and dose rates to body organs. The HF model was developed to address radiation exposure scenarios involving combined exposures to alpha, beta, and gamma radiations and can be used in circumstances where only one type of radiation is involved. Under a plausible but not yet validated set of assumptions and using available megabecquerel (Po-210) to gray dose-conversion factors, acute lethality risk vs. dose curves were developed for circumstances of ingestion exposure to Po-210 by humans. Initial risk calculations were carried out for a reference adult male human (a hypothetical 70-kg person). Results were then modified for application to all ages (except the in utero child) via the use of systemic Po-210 burden. Because of the unavailability of acute lethality data derived from human ingestions of high levels of Po-210, plausibility of risk calculations were evaluated based on data from studies of Po-210 injections in animals. The animal data, although limited, were found to be consistent with the theoretical risk calculations. Key findings are as follows: (1) ingestion (or inhalation) of a few tents of a milligram of Po-210 will likely be fatal to all exposed persons. (2) Lethal intakes are expected to involve fatal damage to the bone marrow which is likely to be compounded by damage caused by higher doses to other organs including the kidneys and liver. (3) Lethal intakes are expected to cause severe damage to the kidney, spleen, stomach

Após a suspensão da medicação e corticoterapia, houve melhora clínica e radiológica em poucos dias.Eosinophilia-myalgia syndrome was described in 1989 in patients who presented progressive and incapacitating myalgia and eosinophilia in blood, fluids and secretions. Most patients report previous L-tryptophan intake. Respiratory manifestations are found in up to 80% of the cases, occasionally as the only manifestation. Treatment includes drug discontinuation and administration of corticosteroids. Here, we describe the case of a 61-year-old female admitted with acute respiratory failure after using L-tryptophan, hydroxytryptophan and other drugs. The patient presented eosinophilia, together with elevated eosinophil counts in the bronchoalveolar lavage and pleural effusion. After discontinuation of the drugs previously used, corticosteroids were administered, resulting in clinical and radiological improvement within just a few days.

    A 69-year-old man was admitted to the emergency department 3 hours after ingestion of a bleaching agent containing hypochlorous acid and sodium hydroxide in a suicide attempt. Enhanced chest computed tomography scans taken on admission indicated an edematous esophagus and air bubbles in the mediastinum. He underwent endotracheal intubation and mechanical ventilation until day 9 because of laryngeal edema. On day 10, his endoscopy indicated diffuse reddish mucosal hyperemia, erosions, and lacerated mucosal lesions in the esophagus that were indicative of grade 2b corrosive esophagitis. Treatment with a proton pump inhibitor was initiated, with which the condition of the esophagus improved, and on day 44, a slight stricture of the upper part of the esophagus was observed. He was discharged on day 64 without any complaints. The ingestion of sodium hypochlorite induces corrosive esophagitis and acute phase of gastritis. Ingestion of any corrosive agent is known as a risk factor for esophagus cancer in the long-term. In such cases with esophageal stricture, esophagectomy is recommended for preventing esophagus cancer. Considering the age of the patient, however, he did not undergo esophagectomy.

    This study investigated whether combined ingestion and mouth rinsing with a carbohydrate solution could improve maximal sprint cycling performance. Twelve competitive male cyclists ingested 100 ml of one of the following solutions 20 min before exercise in a randomized double-blinded counterbalanced order (a) 10% glucose solution, (b) 0.05% aspartame solution, (c) 9.0% maltodextrin solution, or (d) water as a control. Fifteen min after ingestion, repeated mouth rinsing was carried out with 11 × 15 ml bolus doses of the same solution at 30-s intervals. Each participant then performed a 45-s maximal sprint effort on a cycle ergometer. Peak power output was significantly higher in response to the glucose trial (1188 ± 166 W) compared with the water (1036 ± 177 W), aspartame (1088 ± 128 W) and maltodextrin (1024 ± 202 W) trials by 14.7 ± 10.6, 9.2 ± 4.6 and 16.0 ± 6.0% respectively (p sprint was significantly higher in the glucose trial compared with maltodextrin (p sprinting did not differ significantly between treatments (p > .05). These findings suggest that combining the ingestion of glucose with glucose mouth rinsing improves maximal sprint performance. This ergogenic effect is unlikely to be related to changes in blood glucose, sweetness, or energy sensing mechanisms in the gastrointestinal tract.

    Cancer risks associated with ingestion of asbestos are discussed. Asbestos contamination of drinking water is considered. At least 66.5% of the United States water systems are capable of eroding asbestos cement pipes. The ability of water to leach asbestos from asbestos cement pipes can be modified by coatings applied to the inside pipe surface. Asbestos contamination in foods or pharmaceuticals is discussed. Asbestos fibers at concentrations of 1.1 to 172.7 million fibers per liter have been found in beverages. To date, studies supported by the Food and Drug Administration (FDA) have provided no evidence that ingesting asbestos results in an increased cancer risk. The FDA has determined that no prohibition on using asbestos filters in processing food, beverages, and non-parenteral drugs is needed. Toxicological studies on asbestos ingestion and carcinogenicity are reviewed. Epidemiological evaluations of the association between drinking-water supplies containing asbestos and cancer mortality are discussed. It is concluded that the available information is insufficient for assessing the risk of cancer associated with ingesting asbestos.

  20. Estimating Children's Soil/Dust Ingestion Rates through ...

    Science.gov (United States)

    Background: Soil/dust ingestion rates are important variables in assessing children’s health risks in contaminated environments. Current estimates are based largely on soil tracer methodology, which is limited by analytical uncertainty, small sample size, and short study duration. Objectives: The objective was to estimate site-specific soil/dust ingestion rates through reevaluation of the lead absorption dose–response relationship using new bioavailability data from the Bunker Hill Mining and Metallurgical Complex Superfund Site (BHSS) in Idaho, USA. Methods: The U.S. Environmental Protection Agency (EPA) in vitro bioavailability methodology was applied to archived BHSS soil and dust samples. Using age-specific biokinetic slope factors, we related bioavailable lead from these sources to children’s blood lead levels (BLLs) monitored during cleanup from 1988 through 2002. Quantitative regression analyses and exposure assessment guidance were used to develop candidate soil/dust source partition scenarios estimating lead intake, allowing estimation of age-specific soil/dust ingestion rates. These ingestion rate and bioavailability estimates were simultaneously applied to the U.S. EPA Integrated Exposure Uptake Biokinetic Model for Lead in Children to determine those combinations best approximating observed BLLs. Results: Absolute soil and house dust bioavailability averaged 33% (SD ± 4%) and 28% (SD ± 6%), respectively. Estimated BHSS age-specific soil/du

    Microplastics have been documented in marine environments worldwide, where they pose a potential risk to biota. Environmental interactions between microplastics and lower trophic organisms are poorly understood. Coastal shelf seas are rich in productivity but also experience high levels of microplastic pollution. In these habitats, fish have an important ecological and economic role. In their early life stages, planktonic fish larvae are vulnerable to pollution, environmental stress and predation. Here we assess the occurrence of microplastic ingestion in wild fish larvae. Fish larvae and water samples were taken across three sites (10, 19 and 35 km from shore) in the western English Channel from April to June 2016. We identified 2.9% of fish larvae (n = 347) had ingested microplastics, of which 66% were blue fibres; ingested microfibers closely resembled those identified within water samples. With distance from the coast, larval fish density increased significantly (P microplastic concentrations (P microplastics and the incidence of ingestion in fish larvae. Copyright © 2017 Elsevier Ltd.

    Kale is a cruciferous vegetable (Brassicaceae) that contains a large amount of health-promoting phytochemicals. The chronic ingestion of cabbage of the same family is known to accelerate conjugating acetaminophen (AA) and decrease the plasma AA level. Therefore, we examined to clarify the effects of kale on the pharmacokinetics of AA, its glucuronide (AA-G) and sulfate (AA-S). AA was orally administered to rats pre-treated with kale or cabbage (2000 mg/kg/day) for one week. Blood samples were collected from the jugular vein, and the concentrations of AA, AA-G and AA-S were determined. In results, kale ingestion induced an increase in the area under the concentration-time curve (AUC) and a decrease in the clearance of AA, whereas cabbage had almost no influence. In addition, there were significant differences in the AUC of AA-G between the control and kale groups. mRNA expression levels of UDP-glucuronosyltransferases, the enzymes involved in glucuronidation, in the kale group were significantly higher than those in the control group. In conclusion, kale ingestion increased the plasma concentrations of both AA and AA-G. The results suggest that kale ingestion accelerates the glucuronidation of AA, but an increase of plasma AA levels has a different cause than the cause of glucuronidation.

    Background: Protein ingestion is important in enhancing whole-body protein balance in children. The effect of discrete bolus protein ingestion on acute postexercise recovery has yet to be determined.Objective: This study determined the effect of increasing doses of ingested protein on postexercise whole-body leucine balance in healthy, active children.Methods: Thirty-five children (26 boys, 9 girls; age range: 9-13 y; weight mean ± SD: 44.9 ± 10.6 kg) underwent a 5-d adaptation diet (0.95 g protein ⋅ kg(-1) ⋅ d(-1)) before performing 20 min of cycling 3 times with a concurrent, primed, constant infusion of [(13)C]leucine. After exercise, participants consumed an isoenergetic beverage (140 kcal) containing variable amounts of bovine skim-milk protein and carbohydrates (sucrose) (0, 5, 10, and 15 g protein made up with 35, 30, 25, and 20 g carbohydrates, respectively). Blood and breath samples were taken over the 3 h of recovery to determine non-steady state whole-body leucine oxidation (LeuOX) and net leucine balance (LeuBAL).Results: LeuOX (secondary outcome) peaked 60 min after beverage ingestion and demonstrated a relative dose-response over the 3 h of recovery (15 g = 10 > 5 > 0 g; P 10 g (11.6 ± 4.3 mg/kg) > 5 g (5.7 ± 1.9 mg/kg) > 0 g (-3.0 ± 1.7 mg/kg); all P ingestion alone; however, the co-ingestion of carbohydrates and 5 g high-quality dietary protein was sufficient to promote a positive postexercise whole-body protein balance in healthy, active children. Moreover, LeuBAL increased in a dose-dependent manner within the protein range studied. Children should consider consuming a source of dietary protein after physical activity to enhance whole-body anabolism.

    The purpose of this study was to examine the age-related differences in blood pressure, heart rate, and behavioral mood state after caffeine ingestion in younger and older women. Using a placebo-controlled, double-blind design, 10 younger (Y; 18-22 years) and 10 older (O; 50-67 years) healthy women who were moderate consumers of caffeine (self-reported mean intake: Y, 139 +/- 152 mg.day-1; O, 204 +/- 101 mg.day-1) were investigated. All volunteers were characterized for fasting plasma glucose, insulin, free-fatty acids and caffeine levels, body composition, cardiovascular fitness, physical activity, and energy intake. Before and after placebo and caffeine ingestion (5 mg.kg-1 fat-free mass; approximately 208-270 mg) test days, the following variables were measured in all subjects: plasma caffeine levels, heart rate, blood pressure, and behavioral mood state. Results showed that, following caffeine ingestion: (i) both systolic and diastolic blood pressure (SBP and DBP, respectively) increased significantly (p older women (SBP, 128.4 +/- 14.2 vs. 132.1 +/- 13.0 mm Hg (3%); DBP, 80.2 +/- 6.9 vs. 83.4 +/- 7.5 mm Hg (4%), whereas only DBP increased in the younger women (67.1 +/- 4.7 vs. 69.9 +/- 5.4 mm Hg (4.2%); p older women. Self-reported level of physical activity was inversely related to change in DBP following caffeine ingestion in younger women. In conclusion, blood pressure response is augmented and subjective feelings of behavioral mood state are attenuated to a greater degree in older than in younger women following acute caffeine ingestion. Less physically active younger women are more vulnerable to the pressor response to caffeine than more active younger women. It should be noted that these findings are limited to moderate consumers of caffeine who abstained for 48 h prior to testing, and who ingested caffeine in pill form (approximately 240 mg).

    The upstream wheelspace of an axial air turbine stage complete with nozzle guide vanes (NGVs) and rotor blades (430 mm mean diameter) has been tested with the objective of examining the combined effect of NGVs and rotor blades on the level of mainstream ingestion for different seal flow rates. A simple axial clearance seal was used with the rotor spun up to 6650 rpm by drawing air through it from atmospheric pressure with a large centrifugal compressor. The effect of rotational speed was examined for several constant mainstream flow rates by controlling the rotor speed with an air brake. The circumferential variation in hub static pressure was measured at the trailing edge of the NGVs upstream of the seal gap and was found to affect ingestion significantly. The hub static pressure distribution on the rotor blade leading edges was rotor speed dependent and could not be measured in the experiments. The Denton three-dimensional CFD computer code was used to predict the smoothed time-dependent pressure field for the rotor together with the pressure distribution downstream of the NGVs. The level and distribution of mainstream ingestion, and thus, the seal effectiveness, was determined from nitrous oxide gas concentration measurements and related to static pressure measurements made throughout the wheelspace. With the axial clearance rim seal close to the rotor the presence of the blades had a complex effect. Rotor blades in connection with NGVs were found to reduce mainstream ingestion seal flow rates significantly, but a small level of ingestion existed even for very high levels of seal flow rate.

    Full Text Available Seaweed contains large amounts of various arsenic compounds such as arsenosugars (AsSugs, but their relative toxicities have not yet been fully evaluated. A risk evaluation of dietary arsenic would be necessary. After developing an arsenic speciation analysis of wakame seaweed (Undaria pinnatifida, we conducted a wakame ingestion experiment using volunteers. Five volunteers ingested 300 g of commercial wakame after refraining from seafood for 5 days. Arsenic metabolites in the urine were monitored over a 5-day period after ingestion. Total arsenic concentration of the wakame seaweed was 34.3 ± 2.1 mg arsenic/kg (dry weight, n = 3. Two AsSugs, 3-[5′-deoxy-5′-(dimethyl-arsinoyl-β-ribofuranosyloxy]-propylene glycol (AsSug328 and 3-[5′-deoxy-5′-(dimethyl-arsinoyl-β- ribofuranosyl-oxy]-2-hydroxypropyl-2,3-dihydroxy-propyl phosphate (AsSug482 were detected, but arsenobetaine, dimethylarsinic acid (DMA, monomethylarsonic acid, and inorganic arsenics (iAs were not detected. The major peak was AsSug328, which comprised 89% of the total arsenic. Approximately 30% of the total arsenic ingested was excreted in the urine during the 5-day observation. Five arsenic compounds were detected in the urine after ingestion, the major one being DMA, which comprised 58.1 ± 5.0% of the total urinary arsenic excreted over the 5 days. DMA was believed to be metabolized not from iAs but from AsSugs, and its biological half-time was approximately 13 h.

    Experimental vertical total electron content (VTEC) data given by Global Ionospheric Maps (GIM) has been ingested into the IRI version 2012, aiming to obtain grids of effective input parameter values that allow to minimize the difference between the experimental and modeled vertical TEC. Making use of the experience gained with the technique of model adaptation applied to NeQuick (Nava et al., 2005), it has been found possible to compute IRI world grids of effective ionosphere index parameters (IG). The IG grids thus obtained can be interpolated in space and time to calculate with IRI the 3D electron density at any location and also the TEC along any ground-to-satellite ray-path for a given epoch. In this study, the ingestion technique is presented and a posteriori validation, along with an assessment of the capability of the 'ingested' IRI to reproduce the ionosphere day-to-day foF2 variability during disturbed and quiet periods. The foF2 values retrieved are compared with data from about 20 worldwide ionosondes for selected periods of high (year 2000) and moderate to low solar activity (year 2006). It was found that the use of the ingestion scheme enhances the performance of the model when compared with its standard use based on solar activity drivers (R12 and F10.7), especially for high solar activity. As an example, the mean and standard deviation of the differences between experimental and reconstructed F2-peak values for April of year 2000 is 0.09 and 1.28 MHz for ingested IRI, compared to -0.81 and 1.27 MHz (IRI with R12 input) and -0.02 and 1.46 MHz (IRI with F10.7 input).

    2007-06-01

    Full Text Available Forty seven of 150, 15-month-old long weaners died of an acute renal disease syndrome following introduction into an old maize field with a heavy stand of Amaranthus spp. The clinical syndrome was characterised by sudden onset neurological disease with ataxia and recumbency. Subcutaneous oedema, ascites and perirenal oedema with urine odour were the major gross necropsy findings. Renal histopathology revealed marked coagulative renal tubular necrosis of the proximal and distal straight tubules with intertubular haemorrhage. Acute renal failure and perirenal oedema has been described in cattle, pigs, horses and sheep associated with the ingestion of A. hybridus L. and A. retroflexus L. This perirenal oedema syndrome has been widely reported in the Americas, while in South Africa intoxication with the amaranths has only previously been associated with nitrate and possibly oxalate poisoning in cattle.

    Despite the widespread use, suicidal ingestion of isoniazid is a rare condition in Turkey. We reported a case of acute isoniazid intoxication associated with alcohol intake presenting with convulsion, coma and metabolic acidosis. The patient was treated successfully with intravenous pyridoxine administration. Early recognation and appropriate treatment in the intensive care unit is very important to prevent mortality in patients with acute isoniazid toxicity.

    Isoniazid (INH) is the most widely used of the antituberculosis drugs. An acute overdose is potentially fatal and is characterized by the clinical triad of repetitive seizures unresponsive to the usual anticonvulsants, metabolic acidosis with a high anion gap and coma. The diagnosis of INH overdose should be considered in any patient who presents with an unexplained metabolic acidosis and convulsions. The cornerstone of therapy consists in pyridoxine (vitamin B6) and the dose should be equal to the amount of INH ingested. When conservative therapy fails or in case of renal insufficiency, dialysis must be considered. Severe central nervous toxicity can also be caused by chronic ingestion of higher than therapeutic doses of INH. In those cases pyridoxine-therapy can be useful as well. In the present paper a case of acute overdose of INH is reported, followed by a review of the literature.

    Background: Tramadol is a centrally acting analgesic with opioid and nonopioid properties, which extensively used in the relief of mild to moderate pain. Tramadol poisoning is a common cause of acute pharmaceutical poisoning in Iran. There are a few studies about clinical and laboratory findings related to acute tramadol poisoning. Therefore, the aim of this study was to demonstrate the clinical and laboratory findings in tramadol acute poisoning cases. Materials and Methods: This was a retrospective descriptive study of patients with acute tramadol poisoning who referred to Loghman Hakim Hospital Poison Center during January to April 2012. Data such as patient's age, sex, time of ingestion, ingested dose, cause of poisoning, mean duration of hospitalization, patient's clinical presentations, laboratory findings, therapeutic measures, and patient's outcome have collected in a predesigned checklist. Results: A total of 144 patients including 111 men (77%) and 33 women (23%) with acute tramadol poisoning was included in this study. The mean ingested dose was 1971.2 mg (100-20000 mg). Seizure (47.91%) was the most frequent clinical symptom. Blood gas on admission showed pH (7.3 ± 0.1), PCO2 (49.7 ± 8.6 mmHg) and HCO3− (24.1 ± 3.8 mEq/L), indicating pure acute respiratory acidosis may be occurred in tramadol-intoxicated patients. There were significant differences between tramadol-intoxicated cases with and without a seizure with regard to the time interval between ingestion and admission on hospital, ingested dose and PCO2. Conclusion: Seizure and rise of PCO2 were the most findings in this study. PMID:25535500

    This study examined effects of 4 weeks of caffeine supplementation on endurance performance. Eighteen low-habitual caffeine consumers ( 0.05). Before supplementation, all participants completed one V̇O2peak test, one practice trial and 2 experimental trials (acute 3 mg · kg(-1) caffeine [precaf] and placebo [testpla]). During the supplementation period a second V̇O2peak test was completed on day 21 before a final, acute 3 mg · kg(-1) caffeine trial (postcaf) on day 29. Trials consisted of 60 min cycle exercise at 60% V̇O2peak followed by a 30 min performance task. All participants produced more external work during the precaf trial than testpla, with increases in the caffeine (383.3 ± 75 kJ vs. 344.9 ± 80.3 kJ; Cohen's d effect size [ES] = 0.49; P = 0.001) and placebo (354.5 ± 55.2 kJ vs. 333.1 ± 56.4 kJ; ES = 0.38; P = 0.004) supplementation group, respectively. This performance benefit was no longer apparent after 4 weeks of caffeine supplementation (precaf: 383.3 ± 75.0 kJ vs. postcaf: 358.0 ± 89.8 kJ; ES = 0.31; P = 0.025), but was retained in the placebo group (precaf: 354.5 ± 55.2 kJ vs. postcaf: 351.8 ± 49.4 kJ; ES = 0.05; P > 0.05). Circulating caffeine, hormonal concentrations and substrate oxidation did not differ between groups (all P > 0.05). Chronic ingestion of a low dose of caffeine develops tolerance in low-caffeine consumers. Therefore, individuals with low-habitual intakes should refrain from chronic caffeine supplementation to maximise performance benefits from acute caffeine ingestion.

    This study evaluated the influence of foraging preferences on microplastic ingestion by six marine fish species from the Texas Gulf Coast. A total of 1381 fish were analyzed and 42.4% contained ingested microplastic, inclusive of fiber (86.4%), microbead (12.9% %), and fragment (<1.0%) forms. Despite a substantial overlap in diet, ordination of ingested prey items clustered samples into distinctive species groupings, reflective of the foraging gradient among species. Orthopristis chrysoptera displayed the lowest overall frequency of microplastic ingestion and the most distinctive ordination grouping, indicating their selective invertebrate foraging preferences. Cluster analysis of O. chrysoptera most closely classified microplastic with the ingestion of benthic invertebrates, whereas the ingestion of microplastic by all other species most closely classified with the ingestion of vegetation and shrimp. O. chrysoptera, as selective invertebrate foragers, are less likely to ingest microplastics than species exhibiting generalist foraging preferences and methods of prey capture.

    Ingesting caustic substances represents a common event which may result in serious injuries of the gastrointestinal system. Severity of injury depends on the type of ingested substance: Caustic burns are more frequently associated with acid ingestion and their severity depends on type, concentration, time of exposure, and amount of the ingested substance. We report a case of phosphoric acid ingestion leading to death in a patient with depressive disorder. While reports ingestion of other acids and organophosphates can be found in the literature, there are no reports detailing a death due to phosphoric acid ingestion. We hope that presenting the findings in this case can aid death investigators in future cases that may involve ingestion of such a substance. After autopsy pH, phosphate and calcium ions concentration in the blood were analyzed. The cause of death was due to systemic effects: metabolic acidosis, hypophosphatemia, hypocalcemia, and hyperkalemia.

    Full Text Available The purpose of this study was to investigate the impact of ingesting an amino acid-electrolyte (AAE beverage during upper body resistance exercise on transient muscle hypertrophy, exercise performance, markers of muscle damage, and recovery. Participants (n = 15 performed three sets of six repetitions—bench press, lat pull down, incline press, and seated row—followed by three sets of eight repetitions at 75% of the estimated 1 repetition maximum—triceps kickback, hammer curl, triceps push down, and preacher curl—with 90 s of rest between sets. The final set of the push down/preacher curl was performed to failure. Prior to and immediately post-exercise, as well as 24, 48, and 72 h post exercise, cross-sectional muscle thickness was measured. Blood samples were collected prior to exercise, as well as 24, 48, and 72 h post-exercise for serum creatine kinase (CK analysis. No treatment effect was found for muscle cross-sectional area, repetitions to failure, or serum CK. A main effect (p < 0.001 was observed in the change in serum CK levels in the days following the resistance exercise session. The findings of this study suggest that the acute ingestion of a AAE beverage does not alter acute muscle thickness, performance, perceived soreness and weakness, or markers of muscle damage.

    The objective of this study was to evaluate the substitution of soybean meal for castor seed meal (CSM) in diets for feedlot lambs and the effects of these diets on their ingestive behavior. Fifty male Santa Inês lambs were used. The diets were composed of Tifton 85 hay and a concentrate containing detoxified CSM substituting 0, 25, 50, 75, or 100 % of the soybean meal. There was no effect (P > 0.05) of the CSM levels on the feeding, rumination, idle times, chews and time spent chewing per bolus, total chewing time, number of boli chewed, and number of chews per day. The dry matter (DM) intake decreased linearly (P  0.05) the numbers of feeding, rumination, and idle periods, but had a quadratic effect (P time per feeding activity and on the chewing periods. Substitution of soybean meal for detoxified CSM reduces the DM intake but does not change the ingestive behavior.

    1981-01-01

    Intestinal function in mallard ducklings (Anas platyrhynchos) on a freshwater regime was studied after a 7-day dietary ingestion of 0.25% and 2.5% Prudhoe Bay crude oil (PBCO) or a 2.5% paraffin mixture with an in vivo luminal perfusion technique. Dietary ingestion of 2.5% PBCO may have an effect on the integrity of the duckling intestine. There were no significant effects of PBCO on the absorption of Na, Cl, K, or H2O compared with control animals. The ducklings fed 2.5% paraffin had a significant depression in Na and H2O absorption compared with controls. However, this depression dose not seem to be related to an effect on intestinal mucosa Na-K-ATPase activity.

  12. Methodology for Estimating Ingestion Dose for Emergency Response at SRS

    CERN Document Server

    Simpkins, A A

    2002-01-01

    At the Savannah River Site (SRS), emergency response models estimate dose for inhalation and ground shine pathways. A methodology has been developed to incorporate ingestion doses into the emergency response models. The methodology follows a two-phase approach. The first phase estimates site-specific derived response levels (DRLs) which can be compared with predicted ground-level concentrations to determine if intervention is needed to protect the public. This phase uses accepted methods with little deviation from recommended guidance. The second phase uses site-specific data to estimate a 'best estimate' dose to offsite individuals from ingestion of foodstuffs. While this method deviates from recommended guidance, it is technically defensibly and more realistic. As guidance is updated, these methods also will need to be updated.

    The Antillean manatee inhabits coastal regions of North and Northeastern Brazil and currently is considered an endangered species in the country. Aiming to gather information for the development of public policies focusing on the conservation of manatees, the National Center for Research and Conservation of Aquatic Mammals of the Chico Mendes Institute for Biodiversity has been rescuing, rehabilitating and releasing these mammals since the 1980s. Over the last 36 years, 40 manatees were released by the CMA/ICMBio and four of them were rescued again due to debris ingestion. Two of these manatees died and the other two were taken back into captivity for a new rehabilitation process. The four mammals had confirmed diagnosis of plastic debris ingestion. These findings demonstrate that the environment where the manatees live after being released had a significant amount of garbage which may hinder the success of the species conservation in Brazil.

    2010-04-01

    The occurrence of plastic objects in the digestive tract was assessed in eight species of Procellariiformes collected in southern Brazil and the occurrence of polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs) in the ingested plastics pellets and plastic fragments was evaluated. PCBs were detected in plastic pellets (491 ng g(-1)) and plastic fragments (243-418 ng g(-1)). Among the OCPs, p,p'-DDE had the highest concentrations, ranging from 68.0 to 99.0 ng g(-1). The occurrence of organic pollutants in post-consumer plastics supports the fact that plastics are an important source carrying persistent organic pollutants in the marine environment. Although transfer through the food chain may be the main source of exposure to POPs to seabirds, plastics could be an additional source for the organisms which ingest them, like Procellariiformes which are the seabirds most affected by plastic pollution.

    2009-11-01

    Full Text Available A 32-year-old man presented to the emergency department (ED with lower abdominal pain and constipation. He related chronic ingestion of large amounts of opium. Physical examination showed mild abdominal tenderness and gingival discoloration. Diagnostic studies showed a mild hypochromic, microcytic anemia with basophilic stippling of the red blood cells. Abdominal imaging showed no intra-abdominal pathology. A diagnosis of lead toxicity was confirmed through serum lead levels. The patient was put on chelation therapy and his signs and symptoms started to resolve. As a comprehensive search for other sources of lead was unsuccessful, opium adulterants were considered as the culprit. Chemical analysis of the opium confirmed this. Contaminated drugs have been reported as a source of exposure to toxins such as arsenic or lead. While other reports deal with patients from clinics, this report illustrates lead toxicity from ingestion of contaminated opium in the ED.[West J Emerg Med. 2009;10(4:244-246.

    An eight-year-old, neutered male Airedale terrier was presented for the evaluation of a 45-minute episode of continuous seizure activity after ingesting a salt-flour mixture used as clay for the sculpting of small figurines. Levels of serum sodium (211 mEq/L; reference range, 145 to 158 mEq/L) and chloride (180 mEq/L; reference range, 105 to 122 mEq/L) were elevated. The dog died despite aggressive therapy directed at the hypernatremia. Tissue levels of sodium and chloride were elevated. Brain sodium level (108 mEq/L; reference range, has less than 80 mEq/L) was diagnostic for salt toxicosis. All necropsy findings, except severe hepatocellular necrosis, were consistent with reports of salt poisoning in humans and other species. Hypernatremia from ingestion of salt has not been described previously in the dog.

Both macro- and micro-plastics are found in the ocean, but as yet little is known about their ultimate fate and their impact on marine ecosystems. In this study we present the first evidence that microplastics are already becoming integrated into deep-water organisms. By examining organisms that live on the deep-sea floor we show that plastic microfibres are ingested and internalised by members of at least three major phyla with different feeding mechanisms. These results demonstrate that, despite its remote location, the deep sea and its fragile habitats are already being exposed to human waste to the extent that diverse organisms are ingesting microplastics.

    The indiscriminate disposal of plastic to the environment is of concern. Microscopic plastic litter (microplastic') is increasing in abundance in the marine environment, originating from the fragmentation of plastic items and from industry and personal-care products [1]. On highly impacted beaches, microplastic concentrations (Microplastics are a novel substrate for the adherence of hydrophobic contaminants [1], deposition of eggs [3], and colonization by unique bacterial assemblages [4]. Ingestion by indiscriminate deposit-feeders has been reported, yet physical impacts remain understudied [1]. Here, we show that deposit-feeding marine worms maintained in sediments spiked with microscopic unplasticised polyvinylchloride (UPVC) at concentrations overlapping those in the environment had significantly depleted energy reserves by up to 50% (Figure 1). Our results suggest that depleted energy reserves arise from a combination of reduced feeding activity, longer gut residence times of ingested material and inflammation.

    Full Text Available Clostridium difficile infection (CDI is a leading cause of antibiotic-associated diarrhea, a major nosocomial complication. The infective form of C. difficile is the spore, a dormant and resistant structure that forms under stress. Although spore germination is the first committed step in CDI onset, the temporal and spatial distribution of ingested C. difficile spores is not clearly understood. We recently reported that CamSA, a synthetic bile salt analog, inhibits C. difficile spore germination in vitro and in vivo. In this study, we took advantage of the anti-germination activity of bile salts to determine the fate of ingested C. difficile spores. We tested four different bile salts for efficacy in preventing CDI. Since CamSA was the only anti-germinant tested able to prevent signs of CDI, we characterized CamSa's in vitro stability, distribution, and cytotoxicity. We report that CamSA is stable to simulated gastrointestinal (GI environments, but will be degraded by members of the natural microbiota found in a healthy gut. Our data suggest that CamSA will not be systemically available, but instead will be localized to the GI tract. Since in vitro pharmacological parameters were acceptable, CamSA was used to probe the mouse model of CDI. By varying the timing of CamSA dosage, we estimated that C. difficile spores germinated and established infection less than 10 hours after ingestion. We also showed that ingested C. difficile spores rapidly transited through the GI tract and accumulated in the colon and cecum of CamSA-treated mice. From there, C. difficile spores were slowly shed over a 96-hour period. To our knowledge, this is the first report of using molecular probes to obtain disease progression information for C. difficile infection.

    We describe a case of corrosive tracheo-esophageal fistula following button battery ingestion in a 1-year old nonverbal pediatric patient. The delay in diagnosis was caused by failure to obtain correct history and failure to detect opacity of the battery in the neck at the first visit. The large fistula was successfully treated with division and repair with non absorbable sutures, with interposition of strap muscles between separated trachea and esophagus.

  2. CARBOHYDRATE INGESTION AND EXERCISE: EFFECTS ON METABOLISM AND PERFORMANCE

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

    @@KEY POINTS ■ Carbohydrate is the preferred fuel for most competitive sports;an inadequate supply of carbohydrate in the body often leads to poor performance. ■ Carbohydrate ingestion during exercise increases blood glucose availability and maintains the ability of the body to use carbohydrate as fuel during exercise.When carbohydrate is consumed during exercise,glucose uptake by muscles is increased,and the breakdown of glycogen in the liver into blood glucose is reduced,thus saving liver glycogen until late in exercise.The use of muscle glycogen for energy is generally unaffected by carbohydrate feeding.However,during prolonged running,the breakdown of muscle glycogen may be slowed because the supply of blood glucose is improved when carbohydrate is consumed.These metabolic responses underlie the performance benefit that accompanies carbohydrate ingestion during exercise. ■ There are some minor differences among glucose,sucrose,and maltodextrins in their effects on metabolism,but each of them can enhance performance when ingested in the appropriate quantity during exercise.Fructose alone is not an effective carbohydrate supplement because of its slow absorption and slow conversion by the body to glucose,but when small amounts of fructose are combined with other carbohydrates,fructose can be beneficial. ■ Ingesting carbohydrate at a rate of 30-60 grams per hour can improve exercise erformance.A good way to achieve this carbohydrate intake is to consume 600-to-1200 ml(20-to-40 oz)of a sports drink during each hour of exercise.Consuming carbohydrate in a beverage provides an added benefit of preventing potentially harmful effects of dehydration on performance.

    The benefit of glucose polymer ingestion in addition to 2.5 per cent glucose before and during a prolonged orienteering competition was studied. The final time in the competition in the group ingesting 2.5 per cent glucose (group G, n = 10) was 113 min 37 s +/- 8 min 11 s, and in the group which had additionally ingested glucose polymer (group G + GP, n = 8) 107 min 18s +/- 4 min 41 s (NS). One fifth (21 per cent) of the time difference between the two groups was due to difference in orienteering errors. Group G + GP orienteered the last third of the competition faster than group G (p less than 0.05). The time ratio between the last third of the competition and the first third of the competition was lower in group G + GP than in group G (p less than 0.05). After the competition, there was statistically insignificant tendency to higher serum glucose and lower serum free fatty acid concentrations in group G + GP, and serum insulin concentration was higher in group G + GP than in group G (p less than 0.05). Three subjects reported that they exhausted during the competition. These same three subjects had the lowest serum glucose concentrations after the competition (2.9 mmol.1(-1), 2.9 mmol.1(-1), 3.5 mmol.1(-1] and all of them were from group G. It is concluded that glucose polymer syrup ingestion is beneficial for prolonged psychophysical performance.

    Full Text Available Introduction: The complications relating to the ingestion of foreign bodies, such as retropharyngeal abscess, are of low prevalence, but potentially severe. Objective: To present one case of late evolution retropharyngeal abscess after ingestion of foreign body. Case Report: Female patient presenting with dysphagia, pain upon cervical motion and sensation of foreign body in the pharynx, about one month after removal of foreign body from the level of the cricopharyngeal muscle. In spite of not having fever or leukocytosis, due to the slight difficulty for cervical move and loss of the laryngeal crepitation, simple radiography and computed tomography were carried out in the neck, which showed signs of retropharyngeal abscess. Surgical draining of the abscess and antibiotic therapy led to good evolution of the case and symptoms reversion. Conclusion: The retropharyngeal abscess may occur during several weeks after ingestion of a foreign body. The absence of fever and leukocytosis does not exclude the diagnosis even in immunocompetent patients. A high degree of suspicion leads to the performance of diagnostic exams and suitable procedures.

    - After surgical treatment of gastroesophageal reflux disease dysphagia is a symptom in the majority of patients, with decrease in intensity over time. However, some patients may have persistent dysphagia. - The objective of this investigation was to evaluate the dynamics of water ingestion in patients with postfundoplication dysphagia compared with patients with dysphagia caused by achalasia, idiopathic or consequent to Chagas' disease, and controls. - Thirty-three patients with postfundoplication dysphagia, assessed more than one year after surgery, together with 50 patients with Chagas' disease, 27 patients with idiopathic achalasia and 88 controls were all evaluated by the water swallow test. They drunk, in triplicate, 50 mL of water without breaks while being precisely timed and the number of swallows counted. Also measured was: (a) inter-swallows interval - the time to complete the task, divided by the number of swallows during the task; (b) swallowing flow - volume drunk divided by the time taken; (c) volume of each swallow - volume drunk divided by the number of swallows. - Patients with postfundoplication dysphagia, Chagas' disease and idiopathic achalasia took longer to ingest all the volume, had an increased number of swallows, an increase in interval between swallows, a decrease in swallowing flow and a decrease in water volume of each swallow compared with the controls. There was no difference between the three groups of patients. There was no correlation between postfundoplication time and the results. - It was concluded that patients with postfundoplication dysphagia have similar water ingestion dynamics as patients with achalasia.

    Full Text Available Background. Recent studies suggest that the daily intake of lemon (Citrus limon has a good effect on health, but this has not been confirmed in humans. In our previous studies, it was observed that people who are conscious of their health performed more lemon intake and exercise. An analysis that took this into account was required. Methodology. For 101 middle-aged women in an island area in Hiroshima, Japan, a record of lemon ingestion efforts and the number of steps walked was carried out for five months. The change rates (Δ% of the physical measurements, blood test, blood pressure, and pulse wave measured value during the observation period were calculated, and correlations with lemon intake and the number of steps walked were considered. As a result, it was suggested that daily lemon intake and walking are effective for high blood pressure because both showed significant negative correlation to systolic blood pressure Δ%. Conclusions. As a result of multiple linear regression analysis, it was possible that lemon ingestion is involved more greatly with the blood citric acid concentration Δ% and the number of steps with blood pressure Δ%, and it was surmised that the number of steps and lemon ingestion are related to blood pressure improvement by different action mechanisms.

    2001-05-01

    This unit presents fairly simple assays for measuring the binding of bacteria to macrophages, internalization of bacteria (also called ingestion or phagocytosis), and bacterial killing by macrophages. The first basic protocol describes how to measure the ability of macrophages to ingest bacteria. Because it is critical to remove residual extracellular organisms, the protocol presents two alternative steps to accomplish this: a washing procedure and a more stringent method in which cells are sedimented through sucrose. In addition, it is important to distinguish those bacteria truly ingested by a macrophage from those that are bound to, but not internalized by, the cell. A simple but effective way to do this is described in an alternate protocol. The unit also presents two ways to measure the ability of a macrophage to kill bacteria it has internalized. The first is a straightforward assay in which bacterial colonies are enumerated before and after a killing period; a subsequent colony count will indicate whether the bacteria grew within or were killed by the macrophage. The second protocol describes a way to measure bacterial viability based on bacterial metabolism, in which the ability of bacterial dehydrogenases to mediate the reduction of a tetrazolium salt to purple formazan is monitored by measuring absorbance spectrophotometrically.

    2017-04-01

    The CAP88-PC computer model was developed by the U.S. Environmental Protection Agency to demonstrate compliance under the National Emission Standards for Hazardous Air Pollutants (NESHAPS). The program combines atmospheric transport models with the terrestrial food chain models in the U.S. Nuclear Regulatory Commission Regulatory Guide 1.109 to compute the radionuclide concentrations in the air, on ground surfaces and plants, and the concentrations in food to estimate the dose to individuals living in the area around a facility emitting radionuclides into the atmosphere. CAP88 allows the user to select the size of the assessment area and the receptor locations used to calculate the radionuclide concentrations in non-leafy vegetables, leafy vegetables, milk, and meat consumed by the receptors. Depending on the food scenario selected and the type of calculation ("Population" or "Individual") chosen, the annual effective dose from ingestion can depend on both the size of the assessment area and the location of the receptors. Illustrative examples demonstrate the effect of the choice of these input parameters on the annual effective dose from ingestion. An understanding of the model used in CAP88 and the differences between "Population" and "Individual" run types will enable the CAP88 user to better model the ingestion dose.

  17. Toxoplasma gondii Ingests and Digests Host Cytosolic Proteins

    Science.gov (United States)

    Dou, Zhicheng; McGovern, Olivia L.; Di Cristina, Manlio

    2014-01-01

    ABSTRACT The protozoan parasite Toxoplasma gondii resides within a nonfusogenic vacuole during intracellular replication. Although the limiting membrane of this vacuole provides a protective barrier to acidification and degradation by lysosomal hydrolases, it also physically segregates the parasite from the host cytosol. Accordingly, it has been suggested that T. gondii acquires material from the host via membrane channels or transporters. The ability of the parasite to internalize macromolecules via endocytosis during intracellular replication has not been tested. Here, we show that Toxoplasma ingests host cytosolic proteins and digests them using cathepsin L and other proteases within its endolysosomal system. Ingestion was reduced in mutant parasites lacking an intravacuolar network of tubular membranes, implicating this apparatus as a possible conduit for trafficking to the parasite. Genetic ablation of proteins involved in the pathway is associated with diminished parasite replication and virulence attenuation. We show that both virulent type I and avirulent type II strain parasites ingest and digest host-derived protein, indicating that the pathway is not restricted to highly virulent strains. The findings provide the first definitive evidence that T. gondii internalizes proteins from the host during intracellular residence and suggest that protein digestion within the endolysosomal system of the parasite contributes to toxoplasmosis.

    The intentional ingestion of foreign objects (IIFO)is described more commonly in prison populationsthan in the general population, with an estimatedannual incidence of 1 in 1900 inmates in our statecorrectional facilities. Incidents often involve ingestionof small metal objects (e.g. , paperclips, razor blades)or other commonly available items like pens or eatingutensils. Despite ingestion of relatively sharp objects,most episodes can be clinically managed with eitherobservation or endoscopy. Surgery should be reservedfor those with signs or symptoms of gastrointestinalperforation or obstruction. For those with a history ofIIFO, efforts should focus on prevention of recurrenceas subsequent episodes are associated with highermorbidity, significant healthcare and security costs.The pattern of IIFO is often repetitive, with escalationboth in frequency of ingestions and in number of itemsingested. Little is known about successful preventionstrategies, but efforts to monitor patients and providepsychiatric care are potential best-practice strategies.This article aims to provide state-of-the art review onthe topic, followed by a set of basic recommendations.

  19. Curcumin Ingestion Inhibits Mastocytosis and Suppresses Intestinal Anaphylaxis in a Murine Model of Food Allergy.

    Shannon R M Kinney

    Full Text Available IgE antibodies and mast cells play critical roles in the establishment of allergic responses to food antigens. Curcumin, the active ingredient of the curry spice turmeric, has anti-inflammatory properties, and thus may have the capacity to regulate Th2 cells and mucosal mast cell function during allergic responses. We assessed whether curcumin ingestion during oral allergen exposure can modulate the development of food allergy using a murine model of ovalbumin (OVA-induced intestinal anaphylaxis. Herein, we demonstrate that frequent ingestion of curcumin during oral OVA exposure inhibits the development of mastocytosis and intestinal anaphylaxis in OVA-challenged allergic mice. Intragastric (i.g. exposure to OVA in sensitized BALB/c mice induced a robust IgE-mediated response accompanied by enhanced OVA-IgE levels, intestinal mastocytosis, elevated serum mMCP-1, and acute diarrhea. In contrast, mice exposed to oral curcumin throughout the experimental regimen appeared to be normal and did not exhibit intense allergic diarrhea or a significant enhancement of OVA-IgE and intestinal mast cell expansion and activation. Furthermore, allergic diarrhea, mast cell activation and expansion, and Th2 responses were also suppressed in mice exposed to curcumin during the OVA-challenge phase alone, despite the presence of elevated levels of OVA-IgE, suggesting that curcumin may have a direct suppressive effect on intestinal mast cell activation and reverse food allergy symptoms in allergen-sensitized individuals. This was confirmed by observations that curcumin attenuated the expansion of both adoptively transferred bone marrow-derived mast cells (BMMCs, and inhibited their survival and activation during cell culture. Finally, the suppression of intestinal anaphylaxis by curcumin was directly linked with the inhibition of NF-κB activation in curcumin-treated allergic mice, and curcumin inhibited the phosphorylation of the p65 subunit of NF-κB in BMMCs.

    Paraphenylene diamine (PPD) ingestion is manifesting as one of the more common ways of committing suicide in Southern Punjab, Pakistan, especially Bahawalpur. PPD is an ingredient of a compound commonly known "Kala Pathar" which means "Black Stone" in Urdu. It is readily available in the market at low cost and is used to dye hair and fur. Its intoxication inhibits cellular oxidation and affects the muscles causing rhabdomyolysis. This leads to myoglobinuria followed by renal failure and edema of face and throat resulting in respiratory difficulty. Very little is known about the impact of PPD intoxication on liver tissue. The purpose of the study was to find out the frequency of acute hepatitis following PPD intoxication. We reviewed the medical records of 109 patients with PPD intoxication admitted to Medical Unit-2, Bahawalpur Victoria Hospital from January 1, 2015, to June 30, 2015, in a descriptive, cross-sectional study. We noted the frequency of acute hepatitis and other complications, and we recorded the demographic features, clinical features, and outcomes of these patients. Our study included 32 men (29%) and 77 women (71%). The mean age was 22 ± 3.4 years, and most patients were young women aged 15 to 24 years. Suicidal ingestion was the leading cause of admission for 101 patients (93%). The most common clinical presentation was cervicofacial edema (95%), throat pain (88%), dysphonia (95%), cola-colored urine (100%), and oliguria (95%). Rhabdomyolysis (86%), acute hepatitis (51%), and acute renal failure (63%) were the most common clinical conditions following poisoning. Overall mortality was noted in 39 patients (36%) while all other patients achieved complete clinical recovery (64%). In patients with mortality, 20 of 39 (51%) developed acute hepatitis. Most patients (95%) in our study underwent tracheostomy. The frequency of acute hepatitis in PPD intoxication is high in this population, especially in young women. Measures need to be instituted

    The optimum empiric decontamination therapy for unintentional pediatric mushroom ingestion is not known. We sought to determine case outcomes for unintentional mushroom ingestions in children by decontamination therapies utilized. The 1992-2005 American Association of Poison Control Centers Toxic Exposure Surveillance System was queried for cases of unintentional acute mushroom ingestions in children age <6 years. Cases were excluded if outcome was unknown, if exposure was coded as unrelated to the symptoms, or if there was co-ingestion of a non-mycoid substance. The treatment subgroups analyzed were ipecac, single-dose activated charcoal, and no gastric decontamination. 82,330 cases met the inclusion criteria with 22,454 cases excluded. There were 16 cases with major effects and no deaths. There were 57,531 cases in the three treatment subgroups. There was a significantly smaller percentage of cases with moderate or major outcomes in the ipecac subgroup compared to the no decontamination subgroup. There was a significantly greater percentage of cases with moderate or major outcomes in the activated charcoal compared to the no decontamination subgroup. If decontamination therapy is being performed, and this data suggests it may not be necessary, syrup of ipecac could still be considered an effective option.

  4. Modeling Commercial Turbofan Engine Icing Risk With Ice Crystal Ingestion

    Jorgenson, Philip C. E.; Veres, Joseph P.

    2013-01-01

    The occurrence of ice accretion within commercial high bypass aircraft turbine engines has been reported under certain atmospheric conditions. Engine anomalies have taken place at high altitudes that have been attributed to ice crystal ingestion, partially melting, and ice accretion on the compression system components. The result was degraded engine performance, and one or more of the following: loss of thrust control (roll back), compressor surge or stall, and flameout of the combustor. As ice crystals are ingested into the fan and low pressure compression system, the increase in air temperature causes a portion of the ice crystals to melt. It is hypothesized that this allows the ice-water mixture to cover the metal surfaces of the compressor stationary components which leads to ice accretion through evaporative cooling. Ice accretion causes a blockage which subsequently results in the deterioration in performance of the compressor and engine. The focus of this research is to apply an engine icing computational tool to simulate the flow through a turbofan engine and assess the risk of ice accretion. The tool is comprised of an engine system thermodynamic cycle code, a compressor flow analysis code, and an ice particle melt code that has the capability of determining the rate of sublimation, melting, and evaporation through the compressor flow path, without modeling the actual ice accretion. A commercial turbofan engine which has previously experienced icing events during operation in a high altitude ice crystal environment has been tested in the Propulsion Systems Laboratory (PSL) altitude test facility at NASA Glenn Research Center. The PSL has the capability to produce a continuous ice cloud which are ingested by the engine during operation over a range of altitude conditions. The PSL test results confirmed that there was ice accretion in the engine due to ice crystal ingestion, at the same simulated altitude operating conditions as experienced previously in

The only established treatment is supportive. We report a case of poisoning from Aconitum napellus, ingested by a husband and wife who thought the plant was "mountain chicory". They both had tachyarrhythmias, but the husband had more malignant episodes of hemodynamically unstable wide QRS tachycardia and respiratory paralysis requiring mechanical ventilation.

    Colovesical fistula involving the sigmoid colon is the most common fistulous communication between the gastrointestinal tract and the urinary bladder. These tracts are most commonly associated with diverticulitis but might arise secondary to a neoplasm, inflammatory bowel disease, iatrogenic injuries, radiation therapy, trauma, or foreign bodies. We describe a patient who developed a fistula between the sigmoid colon and bladder secondary to an ingested chicken bone that lodged in a colonic diverticulum. A portion of the foreign body was removed by direct visualization on colonoscopy; the remaining fragment passed spontaneously per urethra after hospital discharge.

    A 40-year-old man with no history of neuropsychiatric illness was taking one 250-mg tablet of mefloquine (MFQ) weekly for malaria prophylaxis while in Tanzania. He experienced no adverse reaction in association with his first two doses. Concurrently with both his third and his fourth dose he consumed about half a litre of whisky. On both occasions he experienced hallucinations, paranoid delusions and suicidal ideation. Thereafter he continued taking the MFQ, abstained completely from ethanol ingestion and had no recurrence of psychiatric symptoms. It is hypothesized that the combination of MFQ and ethanol caused the two episodes of severe psychiatric disturbance. PMID:7859199

    This paper reports on a study set up to assess the corrosive behaviour of mercury and zinc air batteries in the gastric juice environment of the stomach. The results show a relatively rapid rate of corrosion for charged mercury batteries. In contrast, the zinc air battery showed no visible corrosion under the same conditions. In view of the toxic dangers from leakage of mercury batteries, it is recommended that steps be taken to ensure that such batteries do not remain in the acidic environment of the stomach, should ingestion occur.

    The krokodil use disorder is an addictive pathology with quite severe organic effects, especially at the skin level, that causes severe and degenerative necrosis of blood and muscle tissue. Though this disorder has a low prevalence in Spain, compared to the large number of consumers in other countries such as Ukraine or Russia, its consumption is slowly but gradually expanding in countries of the European Union and America. The simplicity of the process of obtaining the substance from desomorphine, together with its high availability and low cost, contribute toward consumers' self-sufficiency. This article presents the case of a user of krokodil and reviews the clinical symptoms of oral ingestion.

    2017-01-01

    Despite the risk of cyanide toxicity and lack of efficacy, amygdalin is still used as alternative cancer treatment. Due to the highly lethal nature of cyanide toxicity, many patients die before getting medical care. Herein, we describe the case of a 73-year-old female with metastatic pancreatic cancer who developed cyanide toxicity from taking amygdalin. Detailed history and physical examination prompted rapid clinical recognition and treatment with hydroxocobalamin, leading to resolution of her cyanide toxicity. Rapid clinical diagnosis and treatment of cyanide toxicity can rapidly improve patients' clinical outcome and survival. Inquiries for any forms of ingestion should be attempted in patients with clinical signs and symptoms suggestive of poisoning.

    To evaluate the effectiveness of a mandatory product recall on the frequency of multiple mini-magnet ingestion at a large tertiary pediatric hospital, and to examine the morbidity and mortality associated with these ingestions. In this retrospective chart review, we searched our institution's electronic patient record for patients aged ingested magnetic foreign bodies between 2002 and 2015, a period that included the mandatory product recall. We compared the frequency and character of ingestions before and after the recall. Comparing the postrecall years (January 1, 2014, to December 31, 2015) with the 2 years immediately preceding the recall year (January 1, 2011, to December 31, 2012) yields an incidence rate ratio of 0.34 (95% CI, 0.18-0.64) for all magnet ingestions and 0.20 (95% CI, 0.08-0.53) for ingestion of multiple magnets. Based on the Fisher exact test, the incidence of both magnet ingestion (P ingestion (P ingestion decreased. There were no deaths in either study period. There was a significant decrease in multiple mini-magnet ingestion following a mandatory product recall. This study supports the effectiveness of the recall, which should bolster efforts to keep it in place in jurisdictions where it is being appealed. More broadly, the result provides general evidence of a recall helping decrease further harm from a product that carries a potential hazard. Copyright © 2017 Elsevier Inc. All rights reserved.

  16. Does the evidence about health risks associated with nitrate ingestion warrant an increase of the nitrate standard for drinking water?

    Directory of Open Access Journals (Sweden)

    Benjamin Nigel

    2006-09-01

    Full Text Available Abstract Several authors have suggested that it is safe to raise the health standard for nitrate in drinking water, and save money on measures associated with nitrate pollution of drinking water resources. The major argument has been that the epidemiologic evidence for acute and chronic health effects related to drinking water nitrate at concentrations near the health standard is inconclusive. With respect to the chronic effects, the argument was motivated by the absence of evidence for adverse health effects related to ingestion of nitrate from dietary sources. An interdisciplinary discussion of these arguments led to three important observations. First, there have been only a few well-designed epidemiologic studies that evaluated ingestion of nitrate in drinking water and risk of specific cancers or adverse reproductive outcomes among potentially susceptible subgroups likely to have elevated endogenous nitrosation. Positive associations have been observed for some but not all health outcomes evaluated. Second, the epidemiologic studies of cancer do not support an association between ingestion of dietary nitrate (vegetables and an increased risk of cancer, because intake of dietary nitrate is associated with intake of antioxidants and other beneficial phytochemicals. Third, 2–3 % of the population in Western Europe and the US could be exposed to nitrate levels in drinking water exceeding the WHO standard of 50 mg/l nitrate, particularly those living in rural areas. The health losses due to this exposure cannot be estimated. Therefore, we conclude that it is not possible to weigh the costs and benefits from changing the nitrate standard for drinking water and groundwater resources by considering the potential consequences for human health and by considering the potential savings due to reduced costs for nitrate removal and prevention of nitrate pollution.

  17. HINCOF-1: a Code for Hail Ingestion in Engine Inlets

    Science.gov (United States)

    Gopalaswamy, N.; Murthy, S. N. B.

    1995-01-01

    One of the major concerns during hail ingestion into an engine is the resulting amount and space- and time-wise distribution of hail at the engine face for a given geometry of inlet and set of atmospheric and flight conditions. The appearance of hail in the capture streamtube is invariably random in space and time, with respect to size and momentum. During the motion of a hailstone through an inlet, a hailstone undergoes several processes, namely impact with other hailstones and material surfaces of the inlet and spinner, rolling and rebound following impact; heat and mass transfer; phase change; and shattering, the latter three due to friction and impact. Taking all of these factors into account, a numerical code, designated HINCOF-I, has been developed for determining the motion hailstones from the atmosphere, through an inlet, and up to the engine face. The numerical procedure is based on the Monte-Carlo method. The report presents a description of the code, along with several illustrative cases. The code can be utilized to relate the spinner geometry - conical or, more effective, elliptical - to the possible diversion of hail at the engine face into the bypass stream. The code is also useful for assessing the influence of various hail characteristics on the ingestion and distribution of hailstones over the engine face.

    Full Text Available Objective. To present a rare case of extensive subcutaneous emphysema and spontaneous pneumomediastinum following ingestion of Ecstasy in a young adult. We also review the relevant literature and discuss how this case supplements it. Case Report. We report a case of a 19-year-old man with a history of painless neck and chest swelling, and no chest pain or breathlessness, after consuming Ecstasy tablets. Radiological imaging showed evidence of pneumomediastinum and extensive subcutaneous emphysema. The patient remained well under observation and his symptoms improved with conservative management. Conclusions. Subcutaneous emphysema and pneumomediastinum after Ecstasy ingestion is uncommon. Cases are often referred to the otolaryngologist as they can present with neck and throat symptoms. Our case showed that the severity of symptoms may not correlate with severity of the anatomical abnormality and that pneumomediastinum should be suspected in Ecstasy users who present with neck swelling despite the absence of chest symptoms. Although all cases reported so far resolved with conservative management, it is important to perform simple investigations to exclude coexisting serious pathology.

J Strength Cond Res 30(10): 2892-2900, 2016-The aim of the present study was to determine the effect of ingesting caffeine dose-matched anhydrous caffeine, coffee, or decaffeinated coffee plus anhydrous caffeine during resistance exercise on performance. Nine resistance-trained men (mean ± SD: age, 24 ± 2 years; weight, 84 ± 8 kg; height, 180 ± 8 cm) completed a squat and bench press exercise protocol at 60% 1 repetition maximum until failure on 5 occasions consuming 0.15 g·kg caffeinated coffee (COF), 0.15 g·kg decaffeinated coffee (DEC), 0.15 g·kg decaffeinated coffee plus 5 mg·kg anhydrous caffeine (D + C), 5 mg·kg anhydrous caffeine (CAF), or a placebo (PLA). Felt arousal and rating of perceived exertion (RPE) were used to assess perceptual variables and heart rate (HR) to assess physiological responses between trials. There were significant differences in total weight lifted for the squat between conditions (p caffeine have the ability to improve performance during a resistance exercise protocol, although possibly not over multiple bouts.

    2014-09-01

    Kale, a cultivar of Brassica oleracea, has attracted a great deal of attention because of its health-promoting effects, which are thought to be exerted through modulation of the intestinal microbiota. The present study was performed to investigate the effects of kale ingestion on the gastrointestinal microbial ecology of mice. 21 male C57BL/6J mice were divided into three groups and housed in a specific pathogen-free facility. The animals were fed either a control diet or experimental diets supplemented with different commercial kale products for 12 weeks. Contents of the caecum and colon of the mice were processed for the determination of active bacterial populations by a bacterial rRNA-based quantification method and short-chain fatty acids by HPLC. rRNAs of Bacteroides-Prevotella, the Clostridium coccoides-Eubacterium rectale group, and Clostridium leptum subgroup constituted the major fraction of microbiota regardless of the composition of the diet. The ratio of Firmicutes to Bacteroidetes was higher in the colon samples of one of the kale diet groups than in the control. The colonic butyrate level was also higher with the kale-supplemented diet. Overall, the ingestion of kale tended to either increase or decrease the activity of specific bacterial groups in the mouse gastrointestinal tract, however, the effect might vary depending on the nutritional composition.

    Plastics and other marine debris affect wildlife through entanglement and by ingestion. We assessed the ingestion of marine debris by seven albatross species in the southwest Atlantic by analyzing stomach contents of birds killed in fisheries. Of the 128 specimens examined, including four Diomedea species (n=78) and three Thalassarche species (n=50), 21 (16.4%) contained 1-4 debris items, mainly in the ventriculus. The most common type was plastic fragments. Debris was most frequent in Diomedea species (25.6%) and, particularly, Diomedea sanfordi (38.9%) and very rare in Thalassarche species (2.0%), presumably reflecting differences in foraging behavior or distribution. Frequency of occurrence was significantly higher in male than female Diomedea albatrosses (39.3% vs. 18.0%). Although levels of accumulated debris were relatively low overall, and unlikely to result in gut blockage, associated toxins might nevertheless represent a health risk for Diomedea albatrosses, compounding the negative impact of other human activities on these threatened species.

    Full Text Available Acute interstitial nephritis (AIN is characterized by inflammation of the renal interstitium and usually occurs in a temporal relationship with the medication. We present a case of an Asian male who had nephrotic range proteinuria and presented with acute kidney injury. The patient reported an acute change in physical appearance and symptomatology after the ingestion of a single dose of sildenafil. Renal biopsy was notable for minimal change disease (MCD with acute and chronic interstitial nephritis. Renal replacement and glucocorticoid therapy were initiated. Renal recovery within six weeks permitted discontinuation of dialysis. AIN superimposed on MCD is a known association of NSAID induced nephropathy. The temporal association and the absence of any new drugs suggest that the AIN was most likely due to the sildenafil. NSAIDs are less likely to have caused the AIN given their remote use. The ease of steroid responsiveness would also suggest another cause as NSAID induced AIN is often steroid resistant. The MCD was most likely idiopathic given the lack of temporal association with a secondary cause. As the number of sildenafil prescriptions increases, more cases of AIN may be identified and physician awareness for this potential drug disease association is necessary.

  3. Acute muscular weakness in children

    Ricardo Pablo Javier Erazo Torricelli

    Full Text Available ABSTRACT Acute muscle weakness in children is a pediatric emergency. During the diagnostic approach, it is crucial to obtain a detailed case history, including: onset of weakness, history of associated febrile states, ingestion of toxic substances/toxins, immunizations, and family history. Neurological examination must be meticulous as well. In this review, we describe the most common diseases related to acute muscle weakness, grouped into the site of origin (from the upper motor neuron to the motor unit. Early detection of hyperCKemia may lead to a myositis diagnosis, and hypokalemia points to the diagnosis of periodic paralysis. Ophthalmoparesis, ptosis and bulbar signs are suggestive of myasthenia gravis or botulism. Distal weakness and hyporeflexia are clinical features of Guillain-Barré syndrome, the most frequent cause of acute muscle weakness. If all studies are normal, a psychogenic cause should be considered. Finding the etiology of acute muscle weakness is essential to execute treatment in a timely manner, improving the prognosis of affected children.

    Full Text Available Purpose: We investigated if oral ingestion of ibuprofen influenced leucocyte recruitment and infiltration following an acute bout of traditional resistance exercise. Methods: Sixteen male subjects were divided into two groups that received the maximum over-the-counter dose of ibuprofen (1200 mg d-1 or a similarly administered placebo following lower body resistance exercise. Muscle biopsies were taken from m.vastus lateralis and blood serum samples were obtained before and immediately after exercise, and at 3 h and 24 h after exercise. Muscle cross-sections were stained with antibodies against neutrophils (CD66b and MPO and macrophages (CD68. Muscle damage was assessed via creatine kinase and myoglobin in blood serum samples, and muscle soreness was rated on a ten-point pain scale. Results: The resistance exercise protocol stimulated a significant increase in the number of CD66b+ and MPO+ cells when measured 3 h post exercise. Serum creatine kinase, myoglobin and subjective muscle soreness all increased post-exercise. Muscle leucocyte infiltration, creatine kinase, myoglobin and subjective muscle soreness were unaffected by ibuprofen treatment when compared to placebo. There was also no association between increases in inflammatory leucocytes and any other marker of cellular muscle damage. Conclusion: Ibuprofen administration had no effect on the accumulation of neutrophils, markers of muscle damage or muscle soreness during the first 24 h of post-exercise muscle recovery.

    1995-12-01

    On Monday, October 16, 1995, the Massachussetts Institue of Technology (MIT, the licensee) notified the US Nuclear Regulatory Commission (NRC) of an incident involving ingestion of phosphorus-32 by a researcher at the MIT Center for Cancer Research. The licensee informed the NRC that a researcher had reported the incident on August 19. The licensee initially estimated the intake as 500 microcuries (19 MBq) and the dose as 4000 millirem (40 mSv) to the individual. On October 12, the licensee informed the researcher that its final intake estimate was 579 microcuries (21 MBq), just under the 600 microcuries (22 MBq) which would represent an overexposure. On October 17, the NRC established an Incident Investigation Team to investigate the case. NRC also contracted with Lawrence Livermore National Laboratory and Oak Ridge Institute for Science and Education to do independent dose assessments of the urine sample data and the whole-body data. The Team concluded that the licensee`s final intake and dose estimates were in accordance with accepted scientific references and NRC guidance. However, recognizing the uncertainties involved in the use of models to simulate human characteristics, the Team determined the intake would be better characterized as likely falling within a range of 500 to 750 microcuries (19--28 NMq). An NRC medical consultant concluded that no symptoms or acute effects should be observed from an intake of this level.

    The pine processionary moth (Thaumetopoea wilkinsoni) is an insect of medical significance in the eastern Mediterranean. This report describes three exposure cases in dogs due to ingestion of this moth's caterpillars in Israel. All three dogs were observed in direct contact with caterpillars or pinecones in infested gardens. The disease course and progression of signs were acute in all three cases, and included vomiting and severe tongue swelling. Physical examination findings included hyperthermia, tachypnoea, respiratory distress, cyanosis and tongue oedema, labial angioedema, ptyalism, bilateral submandibular lymphadenomegaly and conjunctivitis. Severe tongue necrosis and sloughing of its distal portion occurred 2-5 days after admission to the hospital. All dogs recovered and were discharged within 2-7 days of admission. Two staff members, attending one of the dogs, experienced an itchy rash and wheals on their arms, wrists and necks. To the best of our knowledge, this should be the first report of severe oral lesions and tongue necrosis due to contact with T. wilkinsoni caterpillars.

    The interpretation of acetaminophen concentrations obtained prior to 4 hours after an acute, single overdose remains unclear. Patient care decisions in the Emergency Department could be accelerated if such concentrations could reliably exclude the need for treatment. To determine the agreement between a serum acetaminophen concentration obtained less than 4 hours after an acute ingestion and the subsequent 4 + hour concentration, and the predictive accuracy of early concentrations for identifying patients with potentially toxic exposures. A secondary analysis of patients admitted for acetaminophen poisoning at one of the 34 hospitals in eight Canadian cities from 1980 to 2005. We examined serum acetaminophen concentrations obtained less than 4 hours post-ingestion, and again 4 or more hours post-ingestion. For the diagnostic accuracy analysis, we specified a cutpoint of 100 μg/mL (662 μmol/L) obtained between 2 and 4 hours and a subsequent 4 to 20 hour acetaminophen concentration above the nomogram treatment line of 150 μg/mL (993 μmol/L). Of 2454 patients identified, 879 (36%) had a subsequent acetaminophen concentration above the nomogram treatment line. The 2-4 hour concentration demonstrated a sensitivity of 0.96 [95% CI; 0.94, 0.97] and a negative likelihood ratio of 0.070 [0.048, 0.10]. Coingested opioids reduced this sensitivity to 0.91 [0.83, 0.95], and antimuscarinics to 0.86 [0.72, 0.94]. Only very low to undetectable acetaminophen concentrations prior to 4 hours reliably excluded a subsequent concentration over the treatment line. Applying an acetaminophen concentration cutpoint of 100 μg/mL (662 μmol/L) at 2-4 hours after an acute ingestion as a threshold for repeat testing and/or treatment would occasionally miss potentially toxic exposures. Absorption of acetaminophen is only slightly delayed by coingested opioids or antimuscarinics. Our analysis validates the practice of not retesting when the first post-ingestion acetaminophen

    The current study describes a naturally occurring cluster of cases of Wedelia glauca intoxication. Seven of 14 axis deer (Axis axis) and 1 of 8 llamas (Lama glama) in a zoo of Buenos Aires province, Argentina, died suddenly after ingestion of a new batch of alfalfa (Medicago sativa) hay bales contaminated with the hepatotoxic plant W. glauca. Necropsies of 1 deer and 1 llama were performed. Pathological findings in both animals included severe diffuse acute centrilobular hepatocellular necrosis and hemorrhage, and clear yellowish translucent gelatinous edema on the wall of the gall bladder and the serosa of the choledochoduodenal junction. Fragments of W. glauca plants were identified in the hay based on the botanical characteristics of the leaves. Samples of gastric contents were examined by microhistological analysis, which identified epidermal fragments of W. glauca based on the presence of characteristic uniseriate glandular hairs (trichomes), confirming recent ingestion of W. glauca in both cases. The fragments were quantified and represented 5% of all examined vegetal fragments in the deer and 10% in the llama.

    To examine whether edible peptide intake affects neurotransmitter metabolism in the brain, we evaluated the effect of peptides derived from soy proteins or fish collagen on free amino acids and monoamines in the mouse brain. Ingestion of soy peptides led to markedly higher levels of tyrosine, a catecholamine precursor, in the serum, and cerebral cortex compared to those following ingestion of vehicle alone or collagen peptides. Soy peptide ingestion also effectively increased 3-methoxy-4-hydroxyphenylethyleneglycol and normetanephrine, the principal metabolites of noradrenaline, in the cerebral cortex, hippocampus, and brainstem, whereas collagen peptides did not exert such effects. Further, soy peptide ingestion led to a significant increase in noradrenaline itself in the brainstem, where noradrenergic neurons are present. Noradrenergic turnover was also markedly stimulated in these regions after soy peptide ingestion. These in vivo observations suggest that soy peptide ingestion can maintain and promote the synthesis and metabolism of noradrenaline in the brain.

    Plastic ingestion is well documented among marine birds and sea turtles but fewer studies have investigated ingestion in fish, particularly in the Southern Hemisphere. We investigated the frequency of plastic ingestion in 21 species of fish and one species of cephalopod. The overall occurrence of plastic ingestion was 0.3%. Two micro-plastic items were recovered from the gastrointestinal tract of a single Antarctic toothfish (Dissostichus mawsoni). Ingestion rates were similar to other studies of fish conducted in both the Northern and Southern Hemispheres, however comparisons across species and locations are challenging due to the lack of consistency in the identification and classification of plastic debris. In response, we propose a standardised sampling protocol based on the available literature to provide a stronger basis for comparisons among existing and future studies of plastic ingestion in fish.

About 95% of people with acute cholecystitis have gallstones.It is thought that blockage of the cystic duct by a gallstone or local inflammation can lead to acute cholecystitis, but we don't know whether bacterial infection is also necessary.

    Collagen tripeptide (CTP) is a collagen hydrolysate containing a high concentration of tripeptides with a Gly-X-Y sequence, such as Gly-Pro-Hyp. To test the effects of this preparation, we compared the absorption of peptides in humans after ingestion of a tripeptide fraction of CTP (CTP-100), a CTP preparation containing ca. 50% Gly-X-Y tripeptides (CTP-50), and a collagen peptide that did not contain tripeptides (CP). The postprandial levels of Gly-Pro-Hyp and Pro-Hyp in the plasma increased in those subjects who ingested CTP-100 and CTP-50, and were higher with greater Gly-Pro-Hyp ingestion. This demonstrated that collagen hydrolysates were efficiently absorbed when the collagen was ingested in the tripeptide form. Gly-Pro-Hyp and Pro-Hyp were also found in the urine after ingestion of CTP-100 or CTP-50. Similar to the results for the plasma concentration, the urinary excretion of Gly-Pro-Hyp and Pro-Hyp was also dependent on the amount of Gly-Pro-Hyp ingested. This indicates that ingested Gly-Pro-Hyp and generated Pro-Hyp were relatively stable in the body and were transported to the urine in the peptide form. The concentration of Hyp-Gly in the plasma was low after the ingestion of CP and CTP-100 but higher after the ingestion of CTP-50. Overall, our results suggest that tripeptides derived from collagen are absorbed efficiently by the body.

    Foreign body ingestion is common in patients with psychiatric diagnoses. Ingested objects can become impacted in the upper and lower gastrointestinal tract, causing serious complications. We report a case of a schizophrenic who ingested large pieces of computer circuit boards, which impacted at the mid-esophagus, in the stomach, and in the cecum. Endoscopic removal of the esophageal object was unsuccessful, and the foreign objects were removed by esophagotomy and laparotomy. Expeditious removal through endoscopic or surgical means is extremely important, as complications can be life-threatening. This is the first report of ingestion of a computer printed circuit board.

    Nocturnal alcohol ingestion is known to increase obstructive sleep apnea. It is assumed that snoring also increases under the influence of alcohol although only few data are available to support this hypothesis. The aim of this study was to investigate the influence of nocturnal alcohol ingestion on the properties of snoring. Twenty healthy male reported non-snorers (n = 10) and snorers (n = 10) underwent night-time polysomnography at three randomly assigned nights with a blood alcohol concentration (BAC) of 0.0, 0.5 and 0.8 per thousand, respectively. Snoring events were recorded by a room and body contact microphone simultaneously. Loudness and incidence of snoring were calculated and correlated to the total sleep time (TST), body position and sleep stages. Snorers revealed an increase of the apnea-hypopnea-index (AHI) under increasing BAC, whereas no decrease in the nocturnal SAO(2) was detected. Non-snorers had no increase in the AHI but a decrease in SAO(2). Snoring individuals revealed a dose-dependent increase of incidence (TSI) and loudness (LSI) of snoring with regard to the TST. The TSI increased by a factor of 1.6 at 0.5 per thousand BAC and by 4.2 at 0.8 per thousand BAC compared to the 0.0 per thousand- BAC-night. The LSI increased threefold at 0.5 per thousand BAC and 14-fold at 0.8 per thousand BAC. Snoring increased to a bigger extent in a supine position compared to non supine and during REM stage as well as Non REM 3/4 stage. Non-snorers did not present any effect of alcohol on the snoring properties with regard to TST, body position and sleep stage. The results indicate that nocturnal alcohol ingestion affects individuals with a reported history of snoring to a greater extent than non-snorers. Non-snorers did not turn into snorers under increasing alcohol influence. The recommendation, to avoid alcohol intake prior to sleep, gains of special clinical importance for individuals already snoring.

    Electronic medical implants have collectively transformed the diagnosis and treatment of many diseases, but have many inherent limitations. Electronic implants require invasive surgeries, operate in challenging microenvironments, and are susceptible to bacterial infection and persistent inflammation. Novel materials and nonconventional device fabrication strategies may revolutionize the way electronic devices are integrated with the body. Ingestible electronic devices offer many advantages compared with implantable counterparts that may improve the diagnosis and treatment of pathologies ranging from gastrointestinal infections to diabetes. This review summarizes current technologies and highlights recent materials advances. Specific focus is dedicated to next-generation materials for packaging, circuit design, and on-board power supplies that are benign, nontoxic, and even biodegradable. Future challenges and opportunities are also highlighted.

    Pesticides in Australia are tightly regulated but it is unknown how this may affect the distribution of misuse and self-harm across Australia, both spatially and within subgroups in the population. We performed an observational study to examine spatial differences in suicide/deliberate poisonings with pesticides in Australia. We examined Coronial inquest cases of self-harm by pesticide ingestion for the years 2001-2013 (n=209). Coronial cases were older, more likely to be male, have lower SES status and live in outer regional areas as opposed to cities when compared to the general population. Case densities (cases/100,000 population) were lower in large capital cities and higher in agricultural areas: despite this half the cases occurred in major cities. Copyright © 2017 Elsevier GmbH.

    Voluntary drug ingestion with benzodiazepine represent today the most frequent method of attempt of autolysis. One must note the difficulties the doctor may find in front such problems to judge the reliability of interviews made in such difficult conditions. Residual disturbances of superior functions, more precisely of vigilance during the period with follow the suicidal action must not be overlooked. Thanks to a clinical scale easily used the residual disturbances have been put in evidence on a sample of 20 subjects who had been admitted with this aim in view in a university ward specialized in psychiatric emergencies. The possibility of continuity within middle range care must allow an improvement of minimum care of such pathologies.

  3. Ingestion of drugs by "parachuting": a unique drug delivery technique.

    Science.gov (United States)

    Kenerson, Katherine L; Lear-Kaul, Kelly C

    2012-06-01

    "Parachuting" is a technique of drug delivery where medications or illicit drugs are ingested by wrapping the drug of choice in a covering, which then will dissolve or unravel in the gastrointestinal tract, thereby releasing the drug for absorption. Parachuting of drugs can entail crushing of a pill prior to packaging to theoretically increase the surface area for absorption or may involve the packaging of a higher than usual dose of a drug in attempts to attain a sustained-release effect as the "parachute" dissolves or unravels. A case is presented in which a prescription drug abuser known to parachute his medications dies from obstruction of his airway by the inhaled packet. Risks of parachuting any drug would include overdose and fatal toxic effect from the drug itself and adverse effects from the packaging including bowel obstruction or perforation, or airway obstruction.

    The purpose of this case report is to illustrate the cause of this patient's headache and sinus pain in the setting of a unique environmental exposure: the patient ingested yogurt only days before presentation. This particular brand of yogurt caused controversy in early September 2013 when the manufacturer voluntarily recalled all flavors. The yogurt was found to be contaminated with Mucor circinelloides. The recall was triggered by the FDA, after receiving many complaints from consumers affected by temporary gastrointestinal symptoms such as abdominal cramping, diarrhea, and nausea. This patient was diagnosed with Rhinocerebral mucormycosis through fungal culture of the affected area. He was specifically colonized with Mucor circinelloides, a variant that rarely causes disease in humans. According to a literature review, only eight cases of mucormycosis in adults caused by this strain were documented before 2009.

    The effects of exercise-induced dehydration and fluid ingestion on men's cognitive performance were assessed. Eleven young men attended separate sessions in which each individual cycled in a controlled environment at 60 % of V.O (2max) for periods of 15, 60, or 120 min without fluid replacement or 120 min with fluid replacement. Immediately following the assigned submaximal exercise period, the participant completed a graded exercise test to voluntary exhaustion. An executive processing test and a short-term memory test were performed prior to and immediately following exercise. Choice-response times during the executive processing test decreased following exercise, regardless of the level of dehydration. Choice-response errors increased following exercise, but only on trials requiring set shifting. Short-term memory performance improved following exercise, regardless of the level of dehydration. Changes in cognitive performance following exercise are hypothesized to be related to metabolic arousal following strenuous physical activity.

  6. Motor and sensory neuropathy secondary to excessive pyridoxine ingestion.

    1985-09-01

    This report documents a case of mixed motor and sensory neuropathy that resulted from ingestion of excessive amounts of pyridoxine. An 81-year-old woman was admitted to the hospital because of difficulty in walking and frequent falls. History revealed that she had been taking large doses of pyridoxine daily for several months as treatment for carpal tunnel syndrome. Diagnostic work-up failed to suggest a cause for her symptoms. Nerve conduction studies revealed slowing of motor conduction velocities, prolonged F wave latencies, and prolonged sensory latencies in both lower extremities. We believe the patient's complaints and the results of nerve conduction studies were secondary to pyridoxine neurotoxicity. Since the bases for this neurotoxicity are unknown, we suggest that treatment of carpal tunnel syndrome with oral pyridoxine be carefully monitored and that dosage limits not be exceeded.

    Full Text Available Despite the risk of cyanide toxicity and lack of efficacy, amygdalin is still used as alternative cancer treatment. Due to the highly lethal nature of cyanide toxicity, many patients die before getting medical care. Herein, we describe the case of a 73-year-old female with metastatic pancreatic cancer who developed cyanide toxicity from taking amygdalin. Detailed history and physical examination prompted rapid clinical recognition and treatment with hydroxocobalamin, leading to resolution of her cyanide toxicity. Rapid clinical diagnosis and treatment of cyanide toxicity can rapidly improve patients’ clinical outcome and survival. Inquiries for any forms of ingestion should be attempted in patients with clinical signs and symptoms suggestive of poisoning.

    2009-12-01

    Full Text Available The effect of resistance exercise with the ingestion of supplementary protein on the activation of the mTOR cascade, in human skeletal muscle has not been fully elucidated. In this study, the impact of a single bout of resistance exercise, immediately followed by a single dose of whey protein isolate (WPI or placebo supplement, on the activation of mTOR signalling was analyzed. Young untrained men completed a maximal single-legged knee extension exercise bout and were randomized to ingest either WPI supplement (n = 7 or the placebo (n = 7. Muscle biopsies were taken from the vastus lateralis before, and 2, 4 and 24 hr post-exercise. WPI or placebo ingestion consumed immediately post-exercise had no impact on the phosphorylation of Akt (Ser473. However, WPI significantly enhanced phosphorylation of mTOR (Ser2448, 4E-BP1 (Thr37/46 and p70S6K (Thr389 at 2 hr post-exercise. This study demonstrates that a single dose of WPI, when consumed in modest quantities, taken immediately after resistance exercise elicits an acute and transient activation of translation initiation within the exercised skeletal muscle.

  10. Effect of cocoa/chocolate ingestion on brachial artery flow-mediated dilation and its relevance to cardiovascular health and disease in humans.

    Monahan, Kevin D

    2012-11-15

    Prospective studies indicate that high intake of dietary flavanols, such as those contained in cocoa/chocolate, are associated with reduced rates of cardiovascular-related morbidity and mortality in humans. Numerous mechanisms may underlie these associations such as favorable effects of flavanols on blood pressure, platelet aggregation, thrombosis, inflammation, and the vascular endothelium. The brachial artery flow-mediated dilation (FMD) technique has emerged as a robust method to quantify endothelial function in humans. Collectively, the preponderance of evidence indicates that FMD is a powerful surrogate measure for firm cardiovascular endpoints, such as cardiovascular-related mortality, in humans. Thus, literally thousands of studies have utilized this technique to document group differences in FMD, as well as to assess the effects of various interventions on FMD. In regards to the latter, numerous studies indicate that both acute and chronic ingestion of cocoa/chocolate increases FMD in humans. Increases in FMD after cocoa/chocolate ingestion appear to be dose-dependent such that greater increases in FMD are observed after ingestion of larger quantities. The mechanisms underlying these responses are likely diverse, however most data suggest an effect of increased nitric oxide bioavailability. Thus, positive vascular effects of cocoa/chocolate on the endothelium may underlie (i.e., be linked mechanistically to) reductions in cardiovascular risk in humans.

    As a consequence of the reactor accidents in Fukushima Daiichi high amounts of radioactive iodine and cesium isotopes were released into the terrestrial and marine Japanese environment. The largest release occurred on March 15, 2011 as a consequence of the containment failure of unit 2. Due to the meteorological conditions large area fallout occurred in the district of Fukushima. Other prefectures in the north of Japan were also contaminated. As a consequence of the high surface contamination the dose limits for drinking water, milk and milky products and food were increased to 200 Bq/kg.It turned out that the contamination of rice was marginal, the contamination of predatory fish higher than that of non-predatory fish. A systematic investigation of food samples could allow a better estimation of ingestion induced exposure.

    Two experiments, each with 10 pregnant ewes (8 treated and 2 controls) were performed to determine if nursing lambs of lactating ewes become intoxicated when the ewes ingest Ipomoea asarifolia but do not show clinical signs themselves. In the first experiment the sheep grazed I. asarifolia in the field while in the second, sheep were maintained in individual bays consuming dry I. asarifolia at 10% and 20% into their ration. In both experiments the lambs remained confined, consuming only their mother's milk. Four of 8 lambs in the grazing experiment and the 4 nursing lambs from the ewes given 20% I. asarifolia showed signs of I. asarifolia poisoning. These results confirm that the tremorgenic compound of I. asarifolia or its toxic metabolites are eliminated in milk and can intoxicate nursing lambs.

    Full Text Available Objective: To compare how and to what extent ingestion of hydrogen water and milk increase breath hydrogen in adults.Methods: Five subjects without specific diseases, ingested distilled or hydrogen water and milk as a reference material that could increase breath hydrogen. Their end-alveolar breath hydrogen was measured.Results: Ingestion of hydrogen water rapidly increased breath hydrogen to the maximal level of approximately 40 ppm 10–15 min after ingestion and thereafter rapidly decreased to the baseline level, whereas ingestion of the same amount of distilled water did not change breath hydrogen (p 0.001. Ingestion of hydrogen water increased both hydrogen peaks and the area under the curve (AUC of breath hydrogen in a dose-dependent manner. Ingestion of milk showed a delayed and sustained increase of breath hydrogen in subjects with milk intolerance for up to 540 min. Ingestion of hydrogen water produced breath hydrogen at AUC levels of 2 to 9 ppm hour, whereas milk increased breath hydrogen to AUC levels of 164 ppm hour for 540 min after drinking.Conclusion: Hydrogen water caused a rapid increase in breath hydrogen in a dose-dependent manner; however, the rise in breath hydrogen was not sustained compared with milk.

    Ingestion of soil by young children may be an important source of exposure to environmental contaminants. Estimates of soil ingestion have been made by several studies using trace elements in a mass-balance approach, but differ substantially between studies and trace elements. We conduct a meta-analysis of four major mass-balance soil ingestion studies conducted on children between one and seven in the summer/fall in the northern United States. The analysis takes advantage of primary data from all studies, and provides a more complete description of soil ingestion among children. The meta-analysis uses data based on the two most reliable trace elements, Al and Si, that have passed a screening to identify and exclude measures with a high likelihood of bias. Details are described in a companion paper. The best linear unbiased predictor is used in a mixed model to estimate soil ingestion for study subjects. Overall, 11% of subject-periods are identified as outliers and excluded from the analysis. An analysis on 216 children based on Al and Si as tracer elements indicates that the mean (median) soil ingestion is 26 mg/day (33 mg/day), with the 95th percentile estimated as 79 mg/day. This systematic approach provides more reliable estimates than individual study results. There is some evidence that soil ingestion increases with a child's age, but insufficient data to distinguish soil ingestion by gender. © 2011 Society for Risk Analysis.

    The inadvertent ingestion of contaminated soil can be a major pathway for chemical exposure to humans. Few studies to date have quantified soil ingestion rates to develop exposure estimates for human health risk assessments (HHRA), and almost all of those were for children in suburban/urban environments. Here we employed a quantitative mass balance tracer approach on a rural population practicing outdoor activities to estimate inadvertent soil ingestion. This study followed 9 subjects over a 13 day period in Cold Lake, Alberta, near the largest in situ thermal heavy oil (bitumen) extraction operation in the world. The mean soil ingestion rate in this study using Al Ce, La, and Si tracers was 32 mg d(-1), with a 90th percentile of 152 mg d(-1) and median soil ingestion rate of 18 mg d(-1). These soil ingestion values are greater than the standard recommended soil ingestion rates for HHRA from Health Canada, and are similar to soil ingestion estimates found in the only other study on a rural population. © 2013.

    Full Text Available In northeast Brazil, nutritional deficiency diseases and schistosomiasis mansoni overlap. An experimental model, wich reproduces the marasmatic clinical form of protein-energy malnutrition, was developed in this laboratory to study these interactions. Albino Swiss mice were fed with a food association ingested usually by human populations in northeast Brazil. This diet (Regional Basic Diet - RBD has negative effects on the growth, food intake and protein utilization in infected mice (acute phase of murine schistosomiasis. Nitrogen balance studies have also shown that infection with Schistosoma mansoni has apparently no effect on protein intestinal absorption in well nourished mice. However, the lowest absorption ratios have been detected among RBD - fed infected animals, suggesting that suprerimposed schistosome infection aggravated the nutritional status of the undernourished host. The serum proteins electrophoretic pattern, as far as albumins are concerned, is quite similar for non-infected undernourished and infected well-fed animals. So, the significance of albumins as a biochemical indicator of the nutritional status of human populations residing in endemic foci of Manson's schistosomiasis, is discussable.

  1. Marine debris ingestion and Thayer's law - The importance of plastic color.

    2016-07-01

    In recent years marine plastic pollution has gained considerable attention as a significant threat to marine animals. Despite the abundant literature related to marine debris ingestion, only a few studies attempted to understand the factors involved in debris ingestion. Plastic ingestion is commonly attributed to visual similarities of plastic fragments to animal's prey items, such as plastic bags and jellyfish. However, this simple explanation is not always coherent with the variety of debris items ingested and with the species' main prey items. We assess differences in the conspicuousness of plastic debris related to their color using Thayer's law to infer the likelihood that visual foragers detect plastic fragments. We hypothesize that marine animals that perceive floating plastic from below should preferentially ingest dark plastic fragments, whereas animals that perceive floating plastic from above should select for paler plastic fragments.

    In addition to monitoring trends in plastic pollution, multi-species surveys are needed to fully understand the pervasiveness of plastic ingestion. We examined the stomach contents of 20 bird species collected from the coastal waters of the eastern North Pacific, a region known to have high levels of plastic pollution. We observed no evidence of plastic ingestion in Rhinoceros Auklet, Marbled Murrelet, Ancient Murrelet or Pigeon Guillemot, and low levels in Common Murre (2.7% incidence rate). Small sample sizes limit our ability to draw conclusions about population level trends for the remaining fifteen species, though evidence of plastic ingestion was found in Glaucous-Winged Gull and Sooty Shearwater. Documenting levels of plastic ingestion in a wide array of species is necessary to gain a comprehensive understanding about the impacts of plastic pollution. We propose that those working with bird carcasses follow standard protocols to assess the levels of plastic ingestion whenever possible.

    Ingestion of fish bones is a common clinical complaint among adult patients. The aim of this study was to evaluate the epidemiological and behavioural risk factors for fish bone ingestion. Between 2009 and 2010, a physician-administered questionnaire was administered to 112 consecutive patients who presented to the emergency department of an adult tertiary hospital with the complaint of fish bone ingestion. The wearing of dentures, the use of utensils to eat fish and the practice of deboning fish in one's mouth were found to be associated with an increased risk of fish bone ingestion. To prevent the occurrence of fish bone ingestion and its possible complications, at-risk populations should be advised on the precautions to take when eating boned fish.

    Clinical experience with hydroxocobalamin in acute cyanide poisoning via ingestion remains limited. This case concerns a 35-year-old mentally ill woman who consumed more than 20 apricot kernels. Published literature suggests each kernel would have contained cyanide concentrations ranging from 0.122 to 4.09 mg/g (average 2.92 mg/g). On arrival, the woman appeared asymptomatic with a raised pulse rate and slight metabolic acidosis. Forty minutes after admission (approximately 70 min postingestion), the patient experienced headache, nausea and dyspnoea, and was hypotensive, hypoxic and tachypnoeic. Following treatment with amyl nitrite and sodium thiosulphate, her methaemoglobin level was 10%. This prompted the administration of oxygen, which evoked a slight improvement in her vital signs. Hydroxocobalamin was then administered. After 24 h, she was completely asymptomatic with normalised blood pressure and other haemodynamic parameters. This case reinforces the safety and effectiveness of hydroxocobalamin in acute cyanide poisoning by ingestion. PMID:22694886

    Full Text Available Many of the abdominal foreign bodies are due to accidental ingestion. Our objective in this case report is to emphasize the importance of the enquiry about the foreign body in the differential diagnosis of acute abdominal pain. According to our knowledge, this is the first report of bowel perforation caused by paper ingestion. A 14-year-old boy with abdominal pain underwent exploratory laparotomy and was found to have abdominal pus and ileal perforation. A crumpled paper was found at the site of perforation. Postoperative enquiry revealed that the patient had ingested 10 crumpled papers. We highlight that recording the history is an important aspect in the management of patients with acute abdominal pain and that foreign bodies should be included in its differential diagnosis.

    Brucellosis is a zoonotic infection that is transmitted from animals to humans by ingestion of infected food products, direct contact with an infected animal, or aerosol inhalation. The disease is endemic in many countries, including the Mediterranean basin, the Middle East, India, Mexico, Central and South America and, central and southwest Asia. Human brucellosis is a systemic infection with a wide clinical spectrum. Although hepatic involvement is very common during the course of chronic brucellosis, hepatic abscess is a very rare complication of Brucella infection. We present a case of hepatic abscess caused by Brucella, which resembled the clinical presentation of surgical acute abdomen.

    Several medications or their metabolites have been associated with urolithiasis, although overall they remain an infrequent cause of urolithiasis. Guaifenesin stones were originally reported as complexed with ephedrine, and subsequent reports have demonstrated pure guaifenesin stones, occurring after long term abuse. We report a case of a 23-year-old male who ingested a large, one time dose of guaifenesin, resulting in acute bilateral ureteral obstruction, which, to our knowledge, is the first such reported case in the literature.

    To investigate the potential for false-positive colorimetric capnometric readings during esophageal intubation after ingestion of carbonated beverages. The study was conducted in the human patient simulation laboratory of a tertiary care pediatric hospital. The sole outcome measurement was the capnometric indicator membrane color after expiration for 10 breaths. Readings were recorded for scenarios simulating 8 different models. For all carbonated beverage trials with a cuffed endotracheal tube (ETT) and those with 2 and 6 oz of beverage in the gastric sac with an uncuffed ETT, a false-positive result was observed on the capnometer's indicator for breaths 1 through 10. The sensitivity of the capnometer for the detection of CO2 after full exhalation of breath 6 for these trials was 100%. For trials containing 12 oz in the gastric sac and an uncuffed ETT, yellow was observed on the capnometer indicator for breaths 1 through 3, tan for breaths 4 through 6, and purple for breath 7. The sensitivity of the capnometer for the detection of adequate CO2 after full exhalation of breath 6 for these trials was 0%. The overall sensitivity of the capnometer for the carbonated beverage models with a cuffed ETT was 100%, whereas the combined sensitivity for the trials with an uncuffed ETT was 67%. Under proper circumstances, a significant potential exists for false-positive colorimetric capnometric results in the presence of even small amounts of carbonated beverages.

  18. The Safety of Ingested Caffeine: A Comprehensive Review

    Full Text Available Caffeine is the most widely consumed psychoactive drug in the world. Natural sources of caffeine include coffee, tea, and chocolate. Synthetic caffeine is also added to products to promote arousal, alertness, energy, and elevated mood. Over the past decade, the introduction of new caffeine-containing food products, as well as changes in consumption patterns of the more traditional sources of caffeine, has increased scrutiny by health authorities and regulatory bodies about the overall consumption of caffeine and its potential cumulative effects on behavior and physiology. Of particular concern is the rate of caffeine intake among populations potentially vulnerable to the negative effects of caffeine consumption: pregnant and lactating women, children and adolescents, young adults, and people with underlying heart or other health conditions, such as mental illness. Here, we review the research into the safety and safe doses of ingested caffeine in healthy and in vulnerable populations. We report that, for healthy adults, caffeine consumption is relatively safe, but that for some vulnerable populations, caffeine consumption could be harmful, including impairments in cardiovascular function, sleep, and substance use. We also identified several gaps in the literature on which we based recommendations for the future of caffeine research.

    1994-11-01

    Final Exit is an "informational aid" advocating the practice of active euthanasia and describing the proper method for the foolproof commission of suicide. Although it has been directed toward assisting the terminally ill patient who desires to terminate suffering, it has been suggested that the widespread availability of this book may result in its abuse. Specifically, there is growing concern that "do-it-yourself suicide manuals" could bring about the fruition of suicidal ideations that are relatively common among mentally ill patients and impressionable adolescents. Described is the suicidal ingestion of cyanide by a physically healthy 30-year-old man. His diary, found next to the body, contains a recipe for suicide copied verbatim from Derek Humphry's Final Exit. Although the decedent's history, the scene investigation, and the external examination strongly suggest an underlying psychiatric disorder, postmortem examination disclosed minimal underlying physical disease. This case graphically illustrates the abuse potential of this literary genre. To our knowledge, this is the first case of its kind to appear in the literature. We recommend that forensic pathologists and medical investigators familiarize themselves with the methods of suicide described in Final Exit.

  1. PAH exposure through soil ingestion: Combining digestion models and bioassays

    Exposure to environmental contaminants through soil ingestion is an important issue in current health risk assessment. Polycyclic aromatic hydrocarbons (PAH) or their metabolites pose risks to humans due to their toxic, mutagenic, carcinogenic or even (anti)estrogenic properties. PAH mobilization from a soil matrix (49.1{+-}1.5 mg PAH/kg DW) was assessed using a Simulator of the Human Intestinal Microbial Ecosystem (SHIME). PAH GC-MS analysis was performed on the pellet and supernatant of SHIME digests and gave 101, 92, 89 and 97% recovery for water, stomach, duodenal and colon digests, respectively. PAH release was highest for the water extract (0.51%) and the stomach digestion (0.44%). Lower mobilized fractions in the duodenum (0.13%) and colon (0.30%) digests could be attributed to PAH complexation with bile salts, dissolved organic matter or colon microbiota. The digestion model provides us with relevant information to what extent soil bound PAHs are mobilized in the gastrointestinal tract and thus reach the gut wall, prior to absorption. (orig.)

    In the present study, a numerical assessment of the performance of fuselage boundary layer ingestion (BLI) propulsion techniques was conducted. This study is an initial investigation into coupling the aerodynamics of the fuselage with a BLI propulsion system to determine if there is sufficient potential to warrant further investigation of this concept. Numerical simulations of flow around baseline, Boundary Layer Controlled (BLC), and propelled boundary layer controlled airships were performed. Computed results showed good agreement with wind tunnel data and previous numerical studies. Numerical simulations and sensitivity analysis were then conducted on four BLI configurations. The two design variables selected for the parametric study of the new configurations were the inlet area and the inlet to exit area ratio. Current results show that BLI propulsors may offer power savings of up to 85% over the baseline configuration. These interim results include the simplifying assumption that inlet ram drag is negligible and therefore likely overstate the reduction in power. It has been found that inlet ram drag is not negligible and should be included in future analysis.

  3. A Digital Preservation Ingest Parsing Agent for Complex Data Objects

    Digital preservation systems are being researched and studied in academia and government-funded efforts all over the world. However, the actual release of a proven production system is still yet to happen. Some efforts have broken ground and present great potential, but major roadblocks still exist. One such obstacle is the complex data object, similar to what is produced by the DOE2000 Electronic Laboratory Notebook (ELN). This research effort will focus on determining a methodology for extracting a complex data object from the ELN, and transforming that into a standard digital preservation ingest file. This standard file type will be based on the Library of Congress Metadata Encoding & Transmission Standard (METS) . A METS file serves as a Submission Information Package (SIP) as defined by the Open Archive Information System (OAIS). In addition to the content information, a complete set of Preservation Description Information (PDI) for the content conformation needs to be collected as well in order to create an Archival Information Package (AIP) which will be used for preservation.

    Full Text Available Data governance is one of the strongest pillars in Data management program which goes hand in hand with data quality. In industrial Data Lake huge amount of unstructured data is getting ingested at high velocity from different source systems. Similarly, through multiple channels of data are getting queried and transformed from Data Lake. Based on 3Vs of big data it’s a real challenge to set up a rule based on traditional data governance system for an Enterprise. In today’s world governance on semi structured or unstructured data on Industrial Data lake is a real issue to the Enterprise in terms of query, create, maintain and storage effectively and secured way. On the other hand different stakeholders i.e. Business, IT and Policy team want to visualize the same data in different view to analyze, imposes constraints, and to place effective workflow mechanis m for approval to the policy makers. In this paper author proposed property graph based governance architecture and process model so that real time unstructured data can effectively govern, visualize, manage and queried from Industrial Data Lake

  5. Formation And Ingestion Of Vortices Into Jet Engines During Operation

    Hua, Ho Wei; Jermy, Mark

    2009-01-01

    Vortices can be produced and ingested into the intake of a turbofan and turbojet aero engine during high power operation near solid surfaces. This can happen either on the runway during take-off or during engine test runs in a test cell. The vortex can throw debris into the intake or cause the compressor to stall causing significant damage to the engine and may require major overhaul. The ability to predict the onset of a vortex is therefore extremely valuable to the industry and could potentially save millions of dollars in overhaul costs. The factors that determines whether or not a vortex forms include engine thrust level, geometric factors such as the distance between the engine core and the ground and the size of the engine core, and flow conditions such as ambient vorticity and height of boundary layer. Computational fluid dynamic studies have been carried out by the authors to attempt to predict the effects that these factors have on the threshold of vortex formation. These works include the first reported studies of numerical predictions of the vortex formation threshold on both the runway or test cell scenarios and include factors that have not been previously studied either numerically or experimentally.

    We report a case of acute, bilateral and severe vision loss after inadvertent consumption of a large quantity of the homoeopathic medication Arnica-30. Severe vomiting which required hospitalization preceded visual symptoms. In the acute stage, pupillary responses to light were absent and fundus examination was normal. Vision loss followed a fluctuating course, with profound loss noted after 6 weeks along with bilateral optic disc pallor. Neuro-ophthalmic examination and detailed investigations were performed, including magnetic resonance imaging, electroretinography (ERG) and visual evoked potentials (VEP). Ocular coherence tomography (OCT) showed gross thinning of the retinal nerve fiber layer. While a differential diagnosis of posterior ischemic optic neuropathy was kept in mind, these findings supported a diagnosis of bilateral toxic optic neuropathy. Arnica-30 is popularly used to accelerate wound healing, including after oculoplastic surgery. While homeopathic medicines are generally considered safe due to the very low concentrations involved, Arnica-30 may be neurotoxic if consumed internally in large quantities.

  8. A pair of pharyngeal gustatory receptor neurons regulates caffeine-dependent ingestion in Drosophila larvae

    2016-07-01

    Full Text Available The sense of taste is an essential chemosensory modality that enables animals to identify appropriate food sources and control feeding behavior. In particular, the recognition of bitter taste prevents animals from feeding on harmful substances. Feeding is a complex behavior comprised of multiple steps, and food quality is continuously assessed. We here examined the role of pharyngeal gustatory organs in ingestion behavior. As a first step, we constructed a gustatory receptor-to-neuron map of the larval pharyngeal sense organs, and examined corresponding gustatory receptor neuron projections in the larval brain. Out of 22 candidate bitter compounds, we found 14 bitter compounds that elicit inhibition of ingestion in a dose-dependent manner. We provide evidence that certain pharyngeal gustatory receptor neurons are necessary and sufficient for the ingestion response of larvae to caffeine. Additionally, we show that a specific pair of pharyngeal gustatory receptor neurons, DP1, responds to caffeine by calcium imaging. In this study we show that a specific pair of gustatory receptor neurons in the pharyngeal sense organs coordinates caffeine sensing with regulation of behavioral responses such as ingestion. Our results indicate that in Drosophila larvae, the pharyngeal gustatory receptor neurons have a major role in sensing food palatability to regulate ingestion behavior. The pharyngeal sense organs are prime candidates to influence ingestion due to their position in the pharynx, and they may act as first level sensors of ingested food.

    In the 1970s in part to avoid inadvertent ingestion, the beverage-can industry changed can construction from pull-tabs to the stay-tabs (remain attached to can after opening) used today. Our purpose is to identify the number of inadvertent ingestions of beverage-can stay-tabs by children recognized at our institution. The medical information system of a children's hospital was searched with key terms to identify cases in which a witnessed or self-reported inadvertent ingestion of a beverage-can stay-tab resulted in a radiograph to rule out presence of a foreign body. Demographics, identification of stay-tab on radiographs, associated abnormalities, and patient management were reviewed. Nineteen cases of stay-tab ingestion were identified over 16 years. Mean age of ingesters was 8.5 years with the majority being teenagers and 15 (79%) >5 years of age. The stay-tab could be seen radiographically only in 4 (21%) cases - all with the stay-tab identified in the stomach. The identification of 19 children who inadvertently ingested beverage-can stay-tabs at a single children's hospital suggests that such ingestions still occur. Radiologists should be aware that stay-tabs are radiographically visible in the minority (21%) of cases. (orig.)

    This study was designed to investigate the pattern, distribution and extent of pulmonary abnormalities in relation to the amount of ingested paraquat as determined with the use of high resolution computed tomography (HRCT). The study included 15 patients exposed to paraquat based on a positive urine assay and the presence of pulmonary abnormalities as detected on HRCT scans. The pattern, distribution and extent of pulmonary abnormalities in relation to the amount of ingested paraquat was evaluated. Patients were classified into five groups based on the amount of paraquat that was ingested. The groups were designated as indirect exposure, minimum exposure (the patient spat out the agent after swallowing), low exposure (<= 30 cc), medium exposure (31-60 cc) and high exposure (61-100 cc). Abnormal lung parenchymal patterns as depicted on HRCT images consisted of ground glass opacity (n = 9), consolidation (n = 9), irregular lines (n = 9) and the presence of nodules (n = 2). The most common distribution was in the lower and subpleural lung zone with no relation to the amount of ingestion. The most common patterns were the presence of irregular lines in the indirect exposure group and ground glass opacity in the high exposure group. The mean number of involved lobes increased in relation to the amount of ingestion. For paraquat poisoning, the pattern and extent of pulmonary abnormalities were related to the amount of ingestion, but the distribution of pulmonary abnormalities was not related to the amount of ingestion

The present 10-year survey aimed to evaluate the epidemiologic features and outcomes of caustic ingestion cases presenting to emergency department.Methods: This is a retrospective cross-sectional study on patients who were admitted to a referral toxicology center during 2004 to 2014, following caustic ingestion. Baseline characteristics, presenting chief complaint, severity of mucosal injury, complications, imaging and laboratory findings as well as outcomes (need for ICU admission, need for surgery, mortality were recorded, reviewing patients’ medical profile, and analyzed using SPSS 22.Results: 348 patients with mean age of 37.76 ± 17.62 years were studied (55.6% male. The mean amount of ingested caustic agent was 106.69 ± 100.24 mL (59.2 % intentional. Intentional ingestions (p < 0.0001, acidic substance (p = 0.054, and higher volume of ingestion (p = 0.021 were significantly associated with higher severity of mucosal damage. 28 (8% cases had died, 53 (15.2% were admitted to ICU, and 115 (33% cases underwent surgery.Conclusion: It seems that, suicidal intention, higher grade of mucosal injury, higher volume of ingestion, lower level of consciousness, lower serum pH, and higher respiratory rate are among the most important predictors of need for ICU admission, need for surgery, and mortality.

    The ingestion of plastic by seabirds has been used as an indicator of pollution in the marine environment. On Kaua'i, HI, USA, 50.0 % of Newell's (Puffinus newelli) and 76.9 % of wedge-tailed shearwater (Ardenna pacifica) fledglings necropsied during 2007-2014 contained plastic items in their digestive tract, while 42.1 % of adult wedge-tailed shearwaters had ingested plastic. For both species, the frequency of plastic ingestion has increased since the 1980s with some evidence that the mass and the number of items ingested per bird have also increased. The color of plastic ingested by the shearwaters was assessed relative to beach-washed plastics by using Jaccard's index (where J = 1 complete similarity). The color (J = 0.65-0.68) of items ingested by both species, and the type ingested by wedge-tailed shearwaters (J = 0.85-0.87), overlapped with plastic available in the local environment indicating moderate selection for plastic color and type. This study has shown that the Hawaiian populations of shearwaters, like many seabird species, provide useful but worrying insights into plastic pollution and the health of our oceans.

    The study investigated the changes in urinary thorium excretion by humans following ingestion of a therapeutic soil, which contains about 10 ppm of thorium. This well-known healing earth in Germany has been considered as an alternative medicine for diarrhoea and gastric hyper-acidity. Six adult volunteers ingested this therapeutic soil in varying quantities for 1-15 days at levels approximating those described in the package insert of the medicine (10-60 g of soil per day). The subjects ingested about 0.1-0.6 mg of thorium daily, which is 100-600 times higher than the normal daily intake of about 1 {mu}g thorium in Germany. All 24-h urine samples collected from the subjects during pre-ingestion, ingestion and post-ingestion periods of the soil were analyzed for {sup 232}Th using inductively coupled plasma mass spectrometry (ICP-MS). The measured excretion values varied in a wide range. Apparently, the high thorium amounts administered did not increase the {sup 232}Th excretion in urine as expected, suggesting that this soil ingestion will not result in a considerably higher and harmful uptake of thorium into the human body.

This well-known healing earth in Germany has been considered as an alternative medicine for diarrhoea and gastric hyper-acidity. Six adult volunteers ingested this therapeutic soil in varying quantities for 1-15 days at levels approximating those described in the package insert of the medicine (10-60 g of soil per day). The subjects ingested about 0.1-0.6 mg of thorium daily, which is 100-600 times higher than the normal daily intake of about 1 microg thorium in Germany. All 24-h urine samples collected from the subjects during pre-ingestion, ingestion and post-ingestion periods of the soil were analyzed for (232)Th using inductively coupled plasma mass spectrometry (ICP-MS). The measured excretion values varied in a wide range. Apparently, the high thorium amounts administered did not increase the (232)Th excretion in urine as expected, suggesting that this soil ingestion will not result in a considerably higher and harmful uptake of thorium into the human body.

    Foreign body ingestion is the second cause of endoscopic emergency in the elderly, and dentures are the most frequent accidently ingested objects. Once in the stomach, their expulsion can be expected in 4 to 6 days. The treatment is wait and see in asymptomatic patients, but preventive endoscopic removal can also be performed. To present 2 scenarios of the outcome and treatment in patients with foreign body ingestion. Patient under study due to weight loss, with a denture detected by abdominal x-ray, ingested inadvertently a year ago. A laparotomy was required as extraction by colonoscopy failed, due to excessive inflammation. The second case, of 24-hour onset, was due to the ingestion of a partial denture. As duodenal endoscopy extraction was unsuccessful, the patient was kept under observation. When it did not pass the caecum, it was extracted by colonoscopy, with no further complications and shorter hospital stay. Follow-up can be by simple abdominal x-ray, with endoscopic management if there is insufficient progress. In one of our cases, the outcome was unfavourable due to time of ingestion, and endoscopic management was not possible, whereas in the second case colonoscopy was performed early with success. Proper diagnostic and timely treatment mark the difference in the progression and outcome of the ingestion of foreign bodies. Copyright © 2016 Academia Mexicana de Cirugía A.C.

    The combination of alcohol with an energy drink (ED) is believed to contribute to risky alcohol-drinking behaviors, such as binge drinking. However, the long-term effects on cognition and reward function that are caused by the repeated binge-like ingestion of alcohol and EDs are still poorly known. The present study examined the effects of a history of repeated exposure to alcohol and/or an ED on short-term memory and alcohol-seeking behavior. Male Wistar rats were given daily intragastric administration of alcohol (3.4g/kg) combined or not with an ED (10.71ml/kg) for 6 consecutive days. The rats were tested for locomotion 15min after the first intragastric treatment. Short-term memory was assessed in the novel object recognition and social discrimination tests 2-3days after the last intragastric administration. The rewarding effect of alcohol was tested 1-3weeks following the last intragastric administration in a conditioned place preference paradigm. The acute binge-like ingestion of alcohol decreased locomotor activity, whereas the combination of alcohol and an ED increased locomotion in the first minutes of assessment. Alcohol exposure produced cognitive deficits in both the object recognition and social discrimination tests, and adding the ED to the alcohol solution did not modify these effects. The combination of alcohol and the ED increased alcohol-induced conditioned place preference. Thus, a history of binge-like alcohol exposure combined with the ED caused subsequent cognitive deficits and increased alcohol seeking behavior, and such behavioral effects might contribute to the progression to alcohol abuse disorders.

    Although a significant proportion of plant tissue is located in roots and other below-ground parts of plants, little is known on the dietary choices of root-feeding insects. This is caused by a lack of adequate methodology which would allow tracking below-ground trophic interactions between insects and plants. Here, we present a DNA-based approach to examine this relationship. Feeding experiments were established where either wheat (Triticum aestivum) or maize (Zea mays) was fed to Agriotes larvae (Coleoptera: Elateridae), allowing them to digest for up to 72 h. Due to the very small amount of plant tissue ingested (max = 6.76 mg), DNA extraction procedures and the sensitivity of polymerase chain reaction (PCR) had to be optimized. Whole-body DNA extracts of larvae were tested for the presence of both rbcL and trnL plastid DNA using universal primers. Moreover, based on cpDNA sequences encoding chloroplast tRNA for leucine (trnL), specific primers for maize and wheat were developed. With both, general and specific primers, plant DNA was detectable in the guts of Agriotes larvae for up to 72 h post-feeding, the maximum time of digestion in these experiments. No significant effect of time since feeding on plant DNA detection success was observed, except for the specific primers in maize-fed larvae. Here, plant DNA detection was negatively correlated with the duration of digestion. Both, meal size and initial mass of the individual larvae did not affect the rate of larvae testing positive for plant DNA. The outcomes of this study represent a first step towards a specific analysis of the dietary choices of soil-living herbivores to further increase our understanding of animal-plant feeding interactions in the soil.

    Full Text Available ABSTRACT Castor bean crops stand out in the Northeastern Brazil for oil production, producing coproducts with potential for animal diets. Thus, this work evaluated the effect on ingestive behavior when 0, 33, 67 and 100% of detoxified castor bean meal (DCBM were included to substitute soy bean meal in diets for sheep. The randomized blocks design was used with five sheep in each treatment. Dry matter intake and neutral detergent fiber intake were not affected (P > .05 by the inclusion of DCBM in the diet, with means of 1362.6 and 582.98 g/animal/day, respectively. Substitution of soybean meal by DCBM did not affect (P > .05 times of rumination, idle and total chewing, with averages of 181.33, 347.04 and 366.24 minute/12 h, respectively. A quadratic effect (P < .05 was found for feeding time, with minimum of 164.56 min/12 h, when 60% of DCBM was included in the diet. A quadratic effect (P < .05 was verified for eating efficiency with maximum of 4.43 g DM/minute and 2.08 g NDF/minute. Rumination efficiency in g DM and NDF/minute were not affected (P < .05, with means of 4.31 and 1.84, respectively. The substitution of soybean meal by DCBM decreases feeding time when 60% of it was used but does not influence the intake of DM and NDF, time spent in ruminating and idle, and total chewing time. The use of 60% of DCBM increases feeding efficiency of DM and NDF, and does not compromise the efficiency of rumination.

    2014-06-01

    This article is part of a Special Issue "Energy Balance". Ingestive behavior in free-ranging populations of nonhuman primates is influenced by resource availability and social group organization and provides valuable insight on the evolution of ecologically adaptive behaviors and physiological systems. As captive populations were established, questions regarding proximate mechanisms that regulate food intake in these animals could be more easily addressed. The availability of these captive populations has led to the use of selected species to understand appetite control or metabolic physiology in humans. Recognizing the difficulty of quantitating food intake in free-ranging groups, the use of captive, singly-housed animals provided a distinct advantage though, at the same time, produced a different social ecology from the animals' natural habitat. However, the recent application of novel technologies to quantitate caloric intake and energy expenditure in free-feeding, socially housed monkeys permits prospective studies that can accurately define how food intake changes in response to any number of interventions in the context of a social environment. This review provides an overview of studies examining food intake using captive nonhuman primates organized into three areas: a) neurochemical regulation of food intake in nonhuman primates; b) whether exposure to specific diets during key developmental periods programs differences in diet preferences or changes the expression of feeding related neuropeptides; and c) how psychosocial factors influence appetite regulation. Because feeding patterns are driven by more than just satiety and orexigenic signals, appreciating how the social context influences pattern of feeding in nonhuman primates may be quite informative for understanding the biological complexity of feeding in humans.

    Acute tonsillitis is an inflammatory process of the tonsillar tissues and is usually infectious in nature. Acute infections of the palatine tonsils predominantly occur in school-aged children, but patients of any age may be affected. Tonsillitis of viral origin is usually treated with supportive care. Bacterial tonsillitis is most commonly caused by Streptococcus pyogenes. Polymicrobial infections and viral pathogens are also important sources of infection. Penicillins remain the treatment of choice for S. pyogenes tonsillitis, and augmented aminopenicillins have gained utility in concert with the increasing incidence of beta-lactamase producing bacteria. We describe the anatomic features and the immunologic function of the palatine tonsils, including a detailed discussion of history and physical examination findings, treatment recommendations, and possible complications of acute tonsillitis. Establishing an accurate diagnosis and initiating appropriate treatment are key components of managing this common pathologic process.

    Despite having played a significant role in the Industry 4.0 era, the Internet of Things is currently faced with the challenge of how to ingest large-scale heterogeneous and multi-type device data. In response to this problem we present a heterogeneous device data ingestion model for an industrial big data platform. The model includes device templates and four strategies for data synchronization, data slicing, data splitting and data indexing, respectively. We can ingest device data from multiple sources with this heterogeneous device data ingestion model, which has been verified on our industrial big data platform. In addition, we present a case study on device data-based scenario analysis of industrial big data.

  8. Poisoning by the ingestion of seeds of the fruit of the "cotieira" (Joannesia princeps

    Directory of Open Access Journals (Sweden)

    Sérgio de Andrade Nishioka

    Full Text Available A 15-year-old boy ingested the core of two seeds of a fruit of Joannesia princeps, a large tree sometimes found planted in sidewalks on streets in Brazilian towns. Four hours after the ingestion, he had several episodes of vomiting and diarrhea, but recovered spontaneously th same day. Poisoning by the ingestion of seeds of Joannesia princeps is possibly not rare, considering that the tree gives plenty of fruit and the seeds have an agreeable flavor, but is probably underestimated as mild cases are unlikely to be reported. Ingestion by small children, that could lead to potentially more severe cases, is in part probably prevented by the hardness of the shells covering the seeds.

    Monitoring plastic ingestion in marine biota is a difficult task, especially regarding ubiquitous microplastics (particles of microplastic ingestion is often limited to laboratory studies. The following review provides a comparison and assessment of different microplastic ingestion monitoring procedures. Emphasis is given to the most important steps of current monitoring practice: (1) selecting suitable indicator species, (2) sampling and sample processing, (3) analytical procedures and (4) the prevention of secondary contamination of the sample. Moreover, an overview on ingestion records of microplastics by different marine feeding guilds is presented, including filter, suspension and deposit feeders as well as predators and scavengers. Lastly, monitoring processes are addressed critically in terms of their suitability for achieving the aims of an appropriate monitoring programme. Recommendations for future research priorities are presented with a focus on the necessity of standardised and comparable monitoring procedures in microplastic detection.

    2007-06-01

    We report a case of foreign body ingestion of a blister pill pack, causing small bowel obstruction. A 76-year-old woman on multiple medications presented with 3 days of progressive abdominal distention, nausea, and vomiting. A computed tomography (CT) scan demonstrated small bowel obstruction with a distinctive metallic foreign body in the distal ileum with associated wall thickening and mesenteric inflammatory changes. At exploratory laparotomy, an impacted, intact blister pill pack was removed from the distal ileum. The ingestion of blister pill packs has been associated with a range of clinical and imaging findings. To our knowledge, this is the only reported case of CT diagnosis of small bowel obstruction caused by blister pack ingestion. Early recognition of the imaging findings of an ingested blister pill pack is important to expedite appropriate management.

    Minoxidil (Rogaine®) is a direct vasodilator that can cause significant toxicity when ingested. We report a case of ingestion of topical minoxidil [Rogaine® (Johnson & Johnson Healthcare Products, Division of McNeil-PPC, Inc)] resulting in refractory hypotension that was successfully managed with the oral α (1) agonist midodrine. A 48-year-old male who ingested an eight ounce bottle of Rogaine® presented to the emergency department. The patient presented with a blood pressure of 57/45 mmHg and a pulse of 84 beats per minute. The patient received IV fluids and multiple vasopressors to maintain an adequate mean arterial pressure. Midodrine, an oral α (1) vasopressor, was added 10 hours post ingestion and was able to maintain an adequate mean arterial pressure. Over the next two days, midodrine was titrated down as his blood pressure returned to baseline. Midodrine may serve as an additional option to treat toxicant induced hypotension.

    Full Text Available Introduction: Determination of type and location of trapped objects and endoscopic observations among children with foreign-body ingestion. Materials and Methods: We evaluated 105 endoscopic records of patients presenting with foreign-body ingestion from 2001–2011. Results: Button batteries were the most common objects removed (41%. The lower segment of the esophagus was the most common trapping site. There was significant correlation between type of foreign body and its location of trapping. Abnormal endoscopic observations were reported in 33% patients. There was significant correlation between the type of foreign body and endoscopic observations. There was also a significant correlation between the location of the foreign body and endoscopic observation. Conclusion: The pattern of foreign-body ingestion is somewhat different in our center compared with other studies. Awareness among parents about the prevention of this accident is an important step in decreasing the incidence of foreign-body ingestion.

  1. Feasibility of an ingestible sensor-based system for monitoring adherence to tuberculosis therapy.

    Directory of Open Access Journals (Sweden)

    Robert Belknap

    Full Text Available Poor adherence to tuberculosis (TB treatment hinders the individual's recovery and threatens public health. Currently, directly observed therapy (DOT is the standard of care; however, high sustaining costs limit its availability, creating a need for more practical adherence confirmation methods. Techniques such as video monitoring and devices to time-register the opening of pill bottles are unable to confirm actual medication ingestions. A novel approach developed by Proteus Digital Health, Inc. consists of an ingestible sensor and an on-body wearable sensor; together, they electronically confirm unique ingestions and record the date/time of the ingestion. A feasibility study using an early prototype was conducted in active TB patients to determine the system's accuracy and safety in confirming co-ingestion of TB medications with sensors. Thirty patients completed 10 DOT visits and 1,080 co-ingestion events; the system showed 95.0% (95% CI 93.5-96.2% positive detection accuracy, defined as the number of detected sensors divided by the number of transmission capable sensors administered. The specificity was 99.7% [95% CI 99.2-99.9%] based on three false signals recorded by receivers. The system's identification accuracy, defined as the number of correctly identified ingestible sensors divided by the number of sensors detected, was 100%. Of 11 adverse events, four were deemed related or possibly related to the device; three mild skin rashes and one complaint of nausea. The system's positive detection accuracy was not affected by the subjects' Body Mass Index (p = 0.7309. Study results suggest the system is capable of correctly identifying ingestible sensors with high accuracy, poses a low risk to users, and may have high patient acceptance. The system has the potential to confirm medication specific treatment compliance on a dose-by-dose basis. When coupled with mobile technology, the system could allow wirelessly observed therapy (WOT for

    Plastic marine debris pollution is rapidly becoming one of the critical environmental concerns facing wildlife in the 21st century. Here we present a risk analysis for plastic ingestion by sea turtles on a global scale. We combined global marine plastic distributions based on ocean drifter data with sea turtle habitat maps to predict exposure levels to plastic pollution. Empirical data from necropsies of deceased animals were then utilised to assess the consequence of exposure to plastics. We modelled the risk (probability of debris ingestion) by incorporating exposure to debris and consequence of exposure, and included life history stage, species of sea turtle and date of stranding observation as possible additional explanatory factors. Life history stage is the best predictor of debris ingestion, but the best-fit model also incorporates encounter rates within a limited distance from stranding location, marine debris predictions specific to the date of the stranding study and turtle species. There is no difference in ingestion rates between stranded turtles vs. those caught as bycatch from fishing activity, suggesting that stranded animals are not a biased representation of debris ingestion rates in the background population. Oceanic life-stage sea turtles are at the highest risk of debris ingestion, and olive ridley turtles are the most at-risk species. The regions of highest risk to global sea turtle populations are off of the east coasts of the USA, Australia and South Africa; the east Indian Ocean, and Southeast Asia. Model results can be used to predict the number of sea turtles globally at risk of debris ingestion. Based on currently available data, initial calculations indicate that up to 52% of sea turtles may have ingested debris. © 2015 John Wiley & Sons Ltd.

    Cobalt is a widely used in the industrial production of hard metals. Cobalt ingestion has been reported to cause widespread systemic toxicity, but its effects on vision have been sparsely reported. The authors report the case of a patient who ingested cattle magnets, which remained in his stomach for an unknown duration of time. These magnets largely consist of cobalt that gradually leached into his blood stream, resulting in protean systemic manifestations, which included optic atrophy.

    Full Text Available Abstract Background The thermogenic and metabolic properties of capsinoids appear to mimic those of the more pungent sister compound capsaicin. However, few data exist on how capsinoid ingestion affects energy expenditure in humans and no data exist on its interaction with exercise. We aimed to determine how ingestion of capsinoids affected energy expenditure, lipid oxidation and blood metabolites at rest and during moderate intensity exercise. Methods Twelve healthy young men (age = 24.3 ± 3 yr, BMI = 25.5 ± 1.7 kg·m-2 were studied on two occasions in a double-blind design following ingestion of either placebo or 10 mg of purified capsinoids at rest, after 90 min of cycling at 55% VO2 peak, and for 30 min into recovery. Subjects ingested the capsules 30 min prior to exercise. Results At rest, following ingestion of capsinoids, we observed increases in VO2 and plasma norepinephrine levels, and decreases in concentrations of serum free fatty acids, plasma glycerol and the respiratory exchange ratio (all P Conclusion The ingestion of 10 mg of capsinoids increased adrenergic activity, energy expenditure, and resulted in a shift in substrate utilization toward lipid at rest but had little effect during exercise or recovery. The changes we observed confirm previous data on the thermogenic and metabolic effects of capsinoids at rest and further promote its potential role as an adjunct weight loss aid, in addition to diet and exercise.

    Enabling user access to Earth science data is a primary goal of NASA's Earth Observing System Data and Information Systems (EOSDIS) programs. NASA's Earth Observing System ClearingHOuse (ECHO) acts as the core metadata repository for EOSDIS's data centers, providing a centralized mechanism for metadata and data discovery and retrieval. ECHO has recently made strides to restructure its API; allowing data partners to streamline and synchronize their metadata ingest using RESTful web services. ECHO's legacy ingest process involves data uploads via FTP with asynchronous result reporting. Data centers provide single xml files or compressed data (zip) files that are unpacked, indexed and stored in ECHO data tables for future search and retrieval. Any problems related to metadata validation and ingest are reported after batch processing of discrete jobs have been completed. With ECHO's new REST-based web services, data providers will receive immediate feedback about the status of their ingested data and can ensure that their data exports are successful as soon as the data is posted to our repository. This presentation will introduce ECHO's potential new and existing data partners to the process of implementing data ingest via its RESTful web services API, providing real-world examples of end-to-end metadata management. Examples of ECHO's support of multi-format metadata ingest using both ECHO10 and ISO 19115 metadata formats will be showcased. This presentation will also pay special attention to tuning a provider's metadata, making it more easily searched and accessed via ECHO's various interfaces.

    Ingestion of carbohydrate during exercise may blunt the stimulation of fat oxidative pathways by raising plasma insulin and glucose concentrations and lowering plasma free fatty acid (FFA) levels, thereby causing a marked shift in substrate oxidation. We investigated the effects of a single 2-h bout of moderate-intensity exercise on the expression of key genes involved in fat and carbohydrate metabolism with or without glucose ingestion in seven healthy untrained men (22.7 +/- 0.6 yr; body mass index: 23.8 +/- 1.0 kg/m(2); maximal O(2) consumption: 3.85 +/- 0.21 l/min). Plasma FFA concentration increased during exercise (P glucose ingestion, whereas fat oxidation (indirect calorimetry) was higher in the fasted state vs. glucose feeding (P expression of pyruvate dehydrogenase kinase-4 (P glucose ingestion during exercise produced minimal effects on the expression of genes involved in carbohydrate utilization. However, glucose ingestion resulted in a decrease in the expression of genes involved in fatty acid transport and oxidation (CD36, carnitine palmitoyltransferase-1, uncoupling protein 3, and 5'-AMP-activated protein kinase-alpha(2); P glucose ingestion during exercise decreases the expression of genes involved in lipid metabolism rather than increasing genes involved in carbohydrate metabolism.

    In the current study, we determined whether increased digestion of starch by high salivary amylase concentrations predicted postprandial blood glucose following starch ingestion. Healthy, nonobese individuals were prescreened for salivary amylase activity and classified as high (HA) or low amylase (LA) if their activity levels per minute fell 1 SD higher or lower than the group mean, respectively. Fasting HA (n = 7) and LA (n = 7) individuals participated in 2 sessions during which they ingested either a starch (experimental) or glucose solution (control) on separate days. Blood samples were collected before, during, and after the participants drank each solution. The samples were analyzed for plasma glucose and insulin concentrations as well as diploid AMY1 gene copy number. HA individuals had significantly more AMY1 gene copies within their genomes than did the LA individuals. We found that following starch ingestion, HA individuals had significantly lower postprandial blood glucose concentrations at 45, 60, and 75 min, as well as significantly lower AUC and peak blood glucose concentrations than the LA individuals. Plasma insulin concentrations in the HA group were significantly higher than baseline early in the testing session, whereas insulin concentrations in the LA group did not increase at this time. Following ingestion of the glucose solution, however, blood glucose and insulin concentrations did not differ between the groups. These observations are interpreted to suggest that HA individuals may be better adapted to ingest starches, whereas LA individuals may be at greater risk for insulin resistance and diabetes if chronically ingesting starch-rich diets.

    Microplastic pollution is recognized as an emerging threat to aquatic ecosystems. One of the main environmental risks associated with microplastics is their bioavailability to marine organisms. Up to date, ingestion has been widely accepted as the sole way for the animals to uptake microplastics. Nevertheless, microplastics have also been found in some organs which are not involved in the process of ingestion. We hypothesize that the animal might uptake microplastics through adherence in addition to ingestion. To test this hypothesis, we collected mussels from the fishery farms, conducted exposure/clearance experiments and analyzed the accumulation of microplastics in specific organ of mussels. Our studies clearly showed the uptake of microplastic in multiple organs of mussels. In the field investigations, we found that the abundance of microplastic by weight but not by individual showed significant difference among organs, and the intestine contained the highest level of microplastics (9.2items/g). In the uptake and clearance experiment, the accumulation and retention of microfibers could also be observed in all tested organs of mussels including foot and mantle. Our results strongly suggest that adherence rather than ingestion led to the accumulation of microplastics in those organs which are not involved in ingestion process. To our best knowledge, it is the first time to propose that adherence is a novel way for animals to uptake microplastics beyond ingestion. This new finding makes us rethink about the bioavailability, accumulation and toxicity of microplastics to aquatic animals. Copyright © 2017 Elsevier B.V. All rights reserved.

  12. The effects of sympathectomy and dexamethasone in rats ingesting sucrose

    Directory of Open Access Journals (Sweden)

    2006-03-01

    Full Text Available Both high-sucrose diet and dexamethasone (D treatment increase plasma insulin and glucose levels and induce insulin resistance. We showed in a previous work (Franco-Colin, et al. Metabolism 2000; 49:1289-1294 that combining both protocols for 7 weeks induced less body weight gain in treated rats without affecting mean daily food intake. Since such an effect may be explained by an increase in caloric expenditure, possibly due to activation of the sympathetic nervous system by sucrose ingestion, in this work, and using 10% sucrose in the drinking water, male Wistar rats were divided into 4 groups. Two groups were sympathectomized using guanethidine (Gu treatment for 3 weeks. One of these groups of rats received D in the drinking water. Of the 2 groups not receiving Gu, one was the control (C and the other received D. After 8 weeks a glucose tolerance test was done. The rats were sacrificed and liver triglyceride (TG, perifemoral muscle lipid, and norepinephrine (NE levels in the liver spleen, pancreas, and heart were determined. Gu-treated rats (Gu and Gu+D groups showed less than 10% NE concentration compared to C and D rats, less daily caloric intake and body-weight gain, more sucrose intake, and better glucose tolerance. The area under the curve after glucose administration correlated significantly with the mean body weight gain of the rats, except for D group. Groups D (D and Gu+D also showed less caloric intake and body-weight gain but higher liver weight and TG concentration and lower peripheral muscle mass. The combination of Gu+D treatments showed some peculiar results: negative body weight gain, a fatty liver, and low muscle mass. Though the glucose tolerance test had the worst results for the D group, it showed the best results in the Gu+D group. There were significant interactions for Guan X Dex by two-way ANOVA test for the area under the curve in the glucose tolerance test, muscle mass, and muscle lipids. The results suggest that

    Limited work has focused on occupational exposures that may increase the risk of cyanide poisoning by ingestion. A retrospective chart review of all admissions for acute cyanide poisoning by ingestion for the years 1988 to 2008 was conducted in a tertiary university hospital serving the largest population in the country working in jewelry and textile facilities. Of the 9 patients admitted to the hospital during the study period, 8 (7 males, 1 female; age 36 ± 11 years, mean ± SD) attempted suicide by ingestion of potassium cyanide used in their profession as goldsmiths or textile industry workers. Five patients had severe neurologic impairment and severe metabolic acidosis (pH 7.02 ± 0.08, mean ± SD) with high anion gap (23 ± 4 mmol/L, mean ± SD). Of the 5 severely intoxicated patients, 3 received antidote therapy (sodium thiosulfate or hydroxocobalamin) and resumed full consciousness in less than 8 hours. All patients survived without major sequelae. Cyanide intoxication by ingestion in our patients was mainly suicidal and occurred in specific jobs where potassium cyanide is used. Metabolic acidosis with high anion is a good surrogated marker of severe cyanide poisoning. Sodium thiosulfate and hydroxocobalamin are both safe and effective antidotes.

    Sulindac is a long-acting nonsteroidal anti-inflammatory drug (NSAID) widely used for the management of osteoarthritis, rheumatoid arthritis, ankylosing sponydlitis, and acute gouty arthritis. Reports of sulindac toxicity in the literature are rare. We report the case of a 22-year old male with a history of bipolar disorder who was brought to the emergency department after ingesting approximately 15 g of sulindac in a suicide attempt. He was found to have acute kidney injury and hyperbilirubinemia. Despite aggressive fluid resuscitation, his renal function progressively worsened requiring the initiation of hemodialysis. Ten days following ingestion of sulindac, he began to develop ischemic skin changes with a gangrenous appearance in his hands and feet. He continued to receive supportive treatment, and his acute kidney injury, hyperbillirubinemia, and ischemic skin necrosis eventually resolved. Clinicians should be aware of this long-acting NSAID and its ability to cause prolonged multisystem organ dysfunction.

    This study investigated the percentage of carbohydrate utilization than can be accounted for by glucose ingested during exercise performed after the ingestion of the potent lipolysis inhibitor Acipimox. Six healthy male volunteers exercised for 3 h on a treadmill at about 45% of their maximal oxygen uptake, 75 min after having ingested 250 mg of Acipimox. After 15-min adaptation to exercise, they ingested either glucose dissolved in water, 50 g at time 0 min and 25 g at time 60 and 120 min (glucose, G) or sweetened water (control, C). Naturally labelled [13C]glucose was used to follow the conversion of the ingested glucose to expired-air CO2. Acipimox inhibited lipolysis in a similar manner in both experimental conditions. This was reflected by an almost complete suppression of the exercise-induced increase in plasma free fatty acid and glycerol and by an almost constant rate of lipid oxidation. Total carbohydrate oxidation evaluated by indirect calorimetry, was similar in both experimental conditions [C, 182, (SEM 21); G, 194 (SEM 16) g.3 h-1], as was lipid oxidation [C, 57 (SEM 6); G, 61 (SEM 3) g.3 h-1]. Exogenous glucose oxidation during exercise G, calculated by the changes in 13C:12C ratio of expired air CO2, averaged 66 (SEM 5) g.3 h-1 (19% of the total energy requirement). Consequently, endogenous carbohydrate utilization was significantly smaller after glucose than after placebo ingestion: 128 (SEM 18) versus 182 (SEM 21) g.3 h-1, respectively (P sweet placebo were absent with glucose ingestion.(ABSTRACT TRUNCATED AT 250 WORDS)

    Densitometry centers commonly request patients abstain from ingesting calcium supplements prior to dual-energy X-ray absorptiometry (DXA) examination to avoid interference with bone mineral density (BMD) measurement. However, it is not clear that this practice is necessary. This study assessed the impact of recent calcium supplement intake on lumbar spine BMD measurement. The phase 1 experiment demonstrated BMD differences when placing a supplement over various areas of two encapsulated phantoms. To determine whether these results were clinically relevant, the phase 2 study enrolled 36 subjects who received spine scans before and after random assignment to ingest one Citracal, OsCal or People's Choice tablet providing 315, 500, and 600 mg of elemental calcium, respectively. The phase 3 study evaluated 15 subjects that had three spine scans with repositioning between to establish BMD precision, and then ingested a calcium carbonate tablet. Post-dosing scans were performed 15 and 30 minutes after tablet ingestion. The difference in L1-L4 BMD on subsequent scans was compared with the study derived least significant change (LSC) of 0.028 g/cm(2). In phase 2, L1-L4 BMD changes outside the LSC occurred in 36% of subjects with 47% having visualized tablets. Similarly, 33% of the phase 3 subjects demonstrated changes outside the LSC after calcium ingestion and 53% of the subjects in phase 3 had tablets visualized. Visualization of calcium tablets was not associated with BMD changes. In conclusion, calcium tablet intake may affect measured L1-L4 BMD within 30 minutes of ingestion. As such, it is appropriate to request patients abstain from calcium tablet ingestion prior to a spine DXA examination.

    Ingestion intakes of (137)Cs of the Czech population were calculated in two different ways - either from the measured activity of (137)Cs in components of food in combination with statistical data about consumption rates or from retention of (137)Cs in the human body obtained by whole body counting or calculated from daily urinary excretion of (137)Cs. Data from the time period since 1986 to 2015 are used. The daily ingestion intake was about 25 Bq d(-1) in 1986 and is around 0.1 Bq d(-1) at present. Both approaches of ingestion intake calculation have their advantages and disadvantages. Ingestion intake calculated from (137)Cs body content was assumed to be the most accurate as it requires fewer assumptions than the calculation from food consumption. However, calculation of (137)Cs intake from food consumption is an important tool for prediction doses after the release of radionuclides into environment. The best agreement exceeding the intakes from urine measurement 5 times at maximum was achieved when intakes calculated from food also included products from the natural environment. Without this, the ingestion intake could be under-predicted seriously up to 6 times, especially in the longer time after the release of (137)Cs into environment. Ingestion intakes up to 11 Bq d(-1) in a group of people with significant consumption of game meat containing elevated activity of (137)Cs activity were included as a special case. Various groups of foodstuffs had varying effects on the total committed effective dose from (137)Cs. Dose estimates for the Czech population from (137)Cs ingestion intake achieved 80 μSv in 1986 and not more than 2 μSv currently and were similar to those incurred by the population of neighbouring countries.

    Dietary methylmercury intake can occur not only through fish ingestion but also through rice ingestion; however, rice does not contain the same beneficial micronutrients as fish. In rural China, where rice is a staple food, associations between prenatal methylmercury exposure (assessed using maternal hair mercury) and impacts on offspring neurodevelopment were investigated. A total of 398 mothers were recruited at parturition at which time a sample of scalp hair was collected. Offspring (n=270, 68%) were assessed at 12 months using the Bayley Scales of Infant Development-II, yielding age-adjusted scores for the Mental Developmental Index (MDI) and Psychomotor Developmental Index (PDI). Among 270 mothers, 85% ingested rice daily, 41% never or rarely ingested fish/shellfish and 11% ingested fish/shellfish at least twice/weekly. Maternal hair mercury averaged 0.41μg/g (median: 0.39μg/g, range: 0.079-1.7μg/g). In unadjusted models, offspring neurodevelopment (both MDI and PDI) was inversely correlated with hair mercury. Associations were strengthened after adjustment for fish/shellfish ingestion, rice ingestion, total energy intake (kcal), and maternal/offspring characteristics for both the MDI [Beta: -4.9, 95% Confidence Interval (CI): -9.7, -0.12] and the PDI (Beta: -2.7, 95% CI: -8.3, 2.9), although confidence intervals remained wide for the latter. For 12-month old offspring living in rural China, prenatal methylmercury exposure was associated with statistically significant decrements in offspring cognition, but not psychomotor development. Results expose potential new vulnerabilities for communities depending on rice as a staple food. Copyright © 2016 Elsevier GmbH. All rights reserved.

    Full Text Available We explore the anti-microbial activity of urine specimens after the ingestion of a commercial cranberry preparation. Twenty subjects without urinary infection, off antibiotics and all supplements or vitamins were recruited. The study was conducted in two phases: in phase 1, subjects collected the first morning urine prior to ingesting 900 mg of cranberry and then at 2, 4 and 6 h. In phase 2, subjects collected urine on 2 consecutive days: on Day 1 no cranberry was ingested (control specimens, on Day 2, cranberry was ingested. The pH of all urine specimens were adjusted to the same pH as that of the first morning urine specimen. Aliquots of each specimen were independently inoculated with Escherichia coli, Klebsiella pneumoniae or Candida albicans. After incubation, colony forming units/ml (CFU ml−1 in the control specimen was compared with CFU ml−1 in specimens collected 2, 4 and 6 h later. Specimens showing ≥50% reduction in CFU ml−1 were considered as having ‘activity’ against the strains tested. In phase 1, 7/20 (35% subjects had anti-microbial activity against E. coli, 13/20 (65% against K. pneumoniae and 9/20 (45% against C. albicans in specimens collected 2–6 h after ingestion of cranberry. In phase 2, 6/9 (67% of the subjects had activity against K. pneumoniae. This pilot study demonstrates weak anti-microbial activity in urine specimens after ingestion of a single dose of commercial cranberry. Anti-microbial activity was noted only against K. pneumoniae 2–6 h after ingestion of the cranberry preparation.

Males are more frequently affected than females in a ratio of 3: 1. More than 45% of patients presented after 48 hours of onset of symptoms. Intestinal obstruction was the commonest cause of acute abdomen (47.6%. External hernia was responsible for 26% of cases of intestinal obstruction. Perforated peptic ulcer was the commonest cause of peritonitis in the present series (31.7% while incidence of biliary peritonitis was only 2.4%.. The clinical accuracy rate was 87%. The mortality in operated cases was high (10% while the over-all mortality rate was 7.5%.
