Prior protein intake may affect phenylalanine kinetics measured in healthy adult volunteers consuming 1 g protein. kg-1. d-1. (1/2097)

Study of the amino acid metabolism of vulnerable groups, such as pregnant women, children and patients, is needed. Our existing protocol is preceded by 2 d of adaptation to a low 13C formula diet at a protein intake of 1 g. kg-1. d-1 to minimize variations in breath 13CO2 enrichment and protein metabolism. To expand on our potential study populations, a less invasive protocol needs to be developed. We have already established that a stable background 13CO2 enrichment can be achieved on the study day without prior adaptation to the low 13C formula. Therefore, this study investigates phenylalanine kinetics in response to variations in prior protein intake. Healthy adult subjects were each fed nutritionally adequate mixed diets containing 0.8, 1.4 and 2.0 g protein. kg-1. d-1 for 2 d. On d 3, subjects consumed an amino acid-based formula diet containing the equivalent of 1 g protein. kg-1. d-1 hourly for 10 h and primed hourly oral doses of L-[1-13C]phenylalanine for the final 6 h. Phenylalanine kinetics were calculated from plasma-free phenylalanine enrichment and breath 13CO2 excretion. A significant quadratic response of prior protein intake on phenylalanine flux (P = 0.012) and oxidation (P = 0.009) was identified, such that both variables were lower following adaptation to a protein intake of 1.4 g. kg-1. d-1. We conclude that variations in protein intake, between 0.8 and 2.0 g. kg-1. d-1, prior to the study day may affect amino acid kinetics and; therefore, it is prudent to continue to control protein intake prior to an amino acid kinetics study.  (+info)

Exhaled and nasal NO levels in allergic rhinitis: relation to sensitization, pollen season and bronchial hyperresponsiveness. (2/2097)

Exhaled nitric oxide is a potential marker of lower airway inflammation. Allergic rhinitis is associated with asthma and bronchial hyperresponsiveness. To determine whether or not nasal and exhaled NO concentrations are increased in allergic rhinitis and to assess the relation between hyperresponsiveness and exhaled NO, 46 rhinitic and 12 control subjects, all nonasthmatic nonsmokers without upper respiratory tract infection, were randomly selected from a large-scale epidemiological survey in Central Norway. All were investigated with flow-volume spirometry, methacholine provocation test, allergy testing and measurement of nasal and exhaled NO concentration in the nonpollen season. Eighteen rhinitic subjects completed an identical follow-up investigation during the following pollen season. Exhaled NO was significantly elevated in allergic rhinitis in the nonpollen season, especially in perennially sensitized subjects, as compared with controls (p=0.01), and increased further in the pollen season (p=0.04), mainly due to a two-fold increase in those with seasonal sensitization. Nasal NO was not significantly different from controls in the nonpollen season and did not increase significantly in the pollen season. Exhaled NO was increased in hyperresponsive subjects, and decreased significantly after methacholine-induced bronchoconstriction, suggesting that NO production occurs in the peripheral airways. In allergic rhinitis, an increase in exhaled nitric oxide on allergen exposure, particularly in hyperresponsive subjects, may be suggestive of airway inflammation and an increased risk for developing asthma.  (+info)

Orally exhaled nitric oxide levels are related to the degree of blood eosinophilia in atopic children with mild-intermittent asthma. (3/2097)

Increased levels of nitric oxide have been found in expired air of patients with asthma, and these are thought to be related to the airway inflammatory events that characterize this disorder. Since, in adults, bronchial inflammatory changes are present even in mild disease, the present study was designed to evaluate whether a significant proportion of children with mild-intermittent asthma could have increased exhaled air NO concentrations. Twenty-two atopic children (aged 11.1+/-0.8 yrs) with mild-intermittent asthma, treated only with inhaled beta2-adrenoreceptor agonists on demand and 22 age-matched controls were studied. NO concentrations in orally exhaled air, measured by chemiluminescence, were significantly higher in asthmatics, as compared to controls (19.4+/-3.3 parts per billion (ppb) and 4.0+/-0.5 ppb, respectively; p<0.01). Interestingly, 14 out of 22 asthmatic children had NO levels >8.8 ppb (i.e. >2 standard deviations of the mean in controls). In asthmatic patients, but not in control subjects, statistically significant correlations were found between exhaled NO levels and absolute number or percentage of blood eosinophils (r=0.63 and 0.56, respectively; p<0.01, each comparison). In contrast, exhaled NO levels were not correlated with forced expiratory volume in one second (FEV1) or forced expiratory flows at 25-75% of vital capacity (FEF25-75%) or forced vital capacity (FVC), either in control subjects, or in asthmatic patients (p>0.1, each correlation). These results suggest that a significant proportion of children with mild-intermittent asthma may have airway inflammation, as shown by the presence of elevated levels of nitric oxide in the exhaled air. The clinical relevance of this observation remains to be established.  (+info)

Salivary contribution to exhaled nitric oxide. (4/2097)

Dietary and metabolic nitrate is distributed from the blood to the saliva by active uptake in the salivary glands, and is reduced to nitrite in the oral cavity by the action of certain bacteria. Since it has been reported that nitric oxide may be formed nonenzymatically from nitrite this study aimed to determine whether salivary nitrite could influence measurements of exhaled NO. Ten healthy subjects fasted overnight and ingested 400 mg potassium nitrate, equivalent to approximately 200 g spinach. Exhaled NO and nasal NO were regularly measured with a chemiluminescence technique up to 3 h after the ingestion. Measurements of exhaled NO were performed with a single-breath procedure, standardized to a 20-s exhalation, at a flow of 0.15 L x s(-1), and oral pressure of 8-10 cmH2O. Values of NO were registered as NO release rate (pmol x s(-1)) during the plateau of exhalation. Exhaled NO increased steadily over time after nitrate load and a maximum was seen at 120 min (77.0+/-15.2 versus 31.2+/-3.0 pmol x s(-1), p<0.01), whereas no increase was detected in nasal NO levels. Salivary nitrite concentrations increased in parallel; at 120 min there was a four-fold increase compared with baseline (1.56+/-0.44 versus 0.37+/-0.09 mM, p<0.05). The nitrite-reducing conditions in the oral cavity were also manipulated by the use of different mouthwash procedures. The antibacterial agent chlorhexidine acetate (0.2%) decreased NO release by almost 50% (p<0.01) 90 min after nitrate loading and reduced the preload control levels by close to 30% (p<0.05). Sodium bicarbonate (10%) also reduced exhaled NO levels, but to a somewhat lesser extent than chlorhexidine acetate. In conclusion, salivary nitric oxide formation contributes to nitric oxide in exhaled air and a large intake of nitrate-rich foods before the investigation might be misinterpreted as an elevated inflammatory activity in the airways. This potential source of error and the means for avoiding it should be considered in the development of a future standardized method for measurements of exhaled nitric oxide.  (+info)

Increased exhaled nitric oxide on days with high outdoor air pollution is of endogenous origin. (5/2097)

The aim of this study was to assess the effect of outdoor air pollution on exhaled levels of endogenously released nitric oxide. To exclude bias from exogenous NO in the recovered exhaled air (residual NO or NO in dead volume) an experimental design was used that sampled NO of endogenous origin only. The validity of the presented experimental design was established in experiments where subjects were exposed to high levels of exogenous NO (cigarette smoke or 480 microg x m(-3) synthetic NO). Subsequent 1 min breathing and a final inhalation of NO-free air proved to be sufficient to attain pre-exposure values. Using the presented method detecting only endogenous NO in exhaled air, 18 subjects were sampled on 4 separate days with different levels of outdoor air pollution (read as an ambient NO level of 4, 30, 138 and 246 microg x m(-3)). On the 2 days with highest outdoor air pollution, exhaled NO was significantly (p<0.001) increased (67-78%) above the mean baseline value assessed on 4 days with virtually no outdoor air pollution. In conclusion, the level of endogenous nitric oxide in exhaled air is increased on days with high outdoor air pollution. The physiological implications of this findings need to be investigated further.  (+info)

LMR spectroscopy: a new sensitive method for on-line recording of nitric oxide in breath. (6/2097)

Laser magnetic resonance spectroscopy (LMRS) is a sensitive and isotope-selective technique for determining low concentrations of gaseous free radicals with high time resolution. We used this technique to analyze the nitric oxide (NO) concentration profile while simultaneously measuring the flow and expired volume during several single breathing cycles. Eight healthy, nonallergic volunteers were investigated. An initial NO peak was found in all breathing cycles before the NO concentration dropped to a relatively stable plateau in the late phase of expiration. The nasal NO peak was significantly higher than the oral NO peak. The nasal NO plateau was always higher than the oral NO plateau. The height of the initial nasal and oral NO peak rose with increasing duration of breath hold, whereas the late expiratory NO plateau changed only little for either the nasal or the oral breathing cycles. Our findings demonstrate, in line with other reports using other techniques, that the nose is the primary source for NO within the airways.  (+info)

Outcome of carotid artery occlusion is predicted by cerebrovascular reactivity. (7/2097)

BACKGROUND AND PURPOSE: The purpose of this study was to investigate the possibility of obtaining prognostic indications in patients with internal carotid occlusion on the basis of intracranial hemodynamic status, presence of previous symptoms of cerebrovascular failure, and baseline characteristics. METHODS: Cerebral hemodynamics were studied with transcranial Doppler ultrasonography. Cerebrovascular reactivity to apnea was calculated by means of the breath-holding index (BHI) in the middle cerebral arteries. Sixty-five patients with internal carotid artery occlusion were followed-up prospectively (median, 24 months), 23 patients were asymptomatic and 42 symptomatic (20 with transient ischemic attack and 22 with stroke). RESULTS: During the follow-up period, 11 symptomatic patients and 1 asymptomatic patient had another ischemic event ipsilateral to carotid occlusion. Among factors considered, only lower BHI values in the middle cerebral arteries ipsilateral to carotid occlusion and older age were significantly associated with the risk of developing symptoms (P=0.002 and P=0.003, respectively; Cox regression multivariate analysis). Based on our data, a cut point of the BHI value for distinguishing between pathological and normal cerebrovascular reactivity was determined to be 0.69. All patients except one, who developed TIA or stroke during the follow-up period, had BHI values ipsilateral to carotid occlusion of <0.69. CONCLUSIONS: These data suggest that impaired cerebrovascular reactivity is predictive for cerebral ischemic events in patients with carotid occlusion.  (+info)

Ontogeny of intestinal safety factors: lactase capacities and lactose loads. (8/2097)

We measured intestinal safety factors (ratio of a physiological capacity to the load on it) for lactose digestion in developing rat pups. Specifically, we assessed the quantitative relationships between lactose load and the series capacities of lactase and the Na+-glucose cotransporter (SGLT-1). Both capacities increased significantly with age in suckling pups as a result of increasing intestinal mass and maintenance of mass-specific activities. The youngest pups examined (5 days) had surprisingly high safety factors of 8-13 for both lactase and SGLT-1, possibly because milk contains lactase substrates other than lactose; it also, however, suggests that their intestinal capacities were being prepared to meet future demands rather than just current ones. By day 10 (and also at day 15), increased lactose loads resulted in lower safety factors of 4-6, values more typical of adult intestines. The safety factor of SGLT-1 in day 30 (weanling) and day 100 (adult) rats was only approximately 1.0. This was initially unexpected, because most adult intestines maintain a modest reserve capacity beyond nutrient load values, but postweaning rats appear to use hindgut fermentation, assessed by gut morphology and hydrogen production assays, as a built-in reserve capacity. The series capacities of lactase and SGLT-1 varied in concert with each other over ontogeny and as lactose load was manipulated by experimental variation in litter size.  (+info)

This study compared three methods of breath sampling for assessment of exposure to volatile organic chemicals. Eleven healthy volunteers were exposed to four of these five chemicals: ethanol, acetone, methyl isobutyl ketone (MIBK), toluene, and halothane. After exposure, venous blood and mixed-exhaled breath, end-exhaled breath, and rebreathed gas were sampled ten times in four hours. The relationship between the concentrations of these chemicals in blood and each type of breath were calculated by linear regression. The calculated blood/gas partition coefficients and the goodness of fit for each breath sampling method were compared in order to evaluate which type of breath sample could best be used to predict blood concentrations. The effect of carbon dioxide correction and the effect of lung function on this relationship were investigated. Rebreathed gas concentrations predicted blood concentrations as well as end-exhaled concentrations and in most cases better than mixed-exhaled concentrations ...

In October 2016, all the Snohomish County District Court (SCDC) judges ruled that the DUI Draeger breath instrument test results cannot be admitted into evidence in any DUI breath test trials in their four divisions (Lynnwood, Everett, Monroe, and Arlington). Such breath tests are the strongest evidence against DUI defendants.. The SCDC judges found that there were numerous Draeger software problems that had not been fully analyzed, tested, and fixed. The judges ruled that the State must first fully test and evaluate the new Draeger instruments to ensure they always produce accurate and reliable breath test results in every DUI case. Only then will the Draeger test results again be admissible in DUI cases.. This October 2016 ruling came after 1 ½ years of local Draeger litigation brought by over 40 plus Snohomish County DUI defense lawyers, including Lynnwood / DUI criminal defense attorney Paul Hanson. This SCDC ruling will make it significantly easier to defend DUI breath test cases in the ...

Stimulated inflammatory cells release large amounts of hydrogen peroxide (H2O2). Breath condensate H2O2 has been shown to be elevated in stable asthmatic children, chronic obstructive pulmonary disease and intubated adult respiratory distress syndrome. In cystic fibrosis airways, where neutrophilic inflammation dominates, it is postulated that H2O2 in breath condensate would be elevated and may be used as a marker of airways inflammation. Expired breath condensate was collected from 16 clinically stable cystic fibrosis (CF) patients (mean age 25.3 yrs, mean forced expiratory volume in one second (FEV1) 50.2%) and 14 normal subjects (mean age 29.9 yrs). Total plasma leukocyte, neutrophil, monocyte and eosinophil counts and lung function were also measured on the day of collection. A method of breath condensate collection excluding the confounding factors of nasal air and saliva contamination was validated and used and H2O2 measured fluorometrically using an optimized assay. The median level of H2O2
Alcohol Breath Tests Plague with Accuracy Problems, New York Times Reports. Breath tests to determine the alcohol content in a persons blood system have been used since shortly after automobiles became available in the early 20th century. They have been relied on for decades to secure convictions in drunken driving cases, but results are now being called into question for their accuracy.. An investigative report in the New York Times claims many of those convictions are made using inaccurate and unreliable breath test results. Some judges are even beginning to question alcohol breath tests and are thousands of drunken driving convictions are being thrown out of court.. All Brands in Different States Producing Inaccurate Results. Alcohol breath testing devices are sensitive instruments that need to be properly calibrated by an experienced technician. Regardless of the brand or the state in which it was being used, the Times found tests being poorly maintained or improperly set up and alcohol ...

Abstract Breath hydrogen tests were performed after a rice meal (3 g of cooked rice/kg of body weight, equivalent to 1 g of carbohydrate/kg of body weight) on 256 village children (age range 1-59 months) who were known hydrogen (H2) producers. Anthropometric measurements were made every three months and growth rates were calculated. A breath H2 excretion pattern that suggested small bowel bacterial overgrowth (SBBO), which was recognized as a transient maximum level of 10 ppm or more at 20-, 40-, or 60-min breath samples following the rice meal, was present in 53 (20.7%) children, and was more frequent in children 36-47 and 48-59 months old. This breath H2 excretion pattern was detected in 48 (33.3%) of 144 children who were rice malabsorbers (> 10 ppm H2 above baseline values in one of the breath samples taken between 90 and 240 min), and in only five (4.5%) of 112 rice absorbers. Children who had SBBO had a high relative risk (10.7) of being rice malabsorbers. Rice malabsorbers have a high relative

Prior to the Melendez-Diaz ruling, state law permitted the District Attorney to admit breath or blood test results by a simple affidavit. The person who administered the breath test would never testify. The chemical analysis of a blood result or breath test was submitted on paper and defense attorneys were not given the opportunity to cross examine the witnesses that performed these crucial tests. A defense attorney could always subpoena the witnesses themselves, but many felt they shouldnt have to. The US Supreme Court essentially agreed and stated in the Melendez-Diaz opinion that the burden is on the prosecution to present its witnesses, not on the defendant to bring those adverse witnesses into court. Remember, when a person is accused of a crime, it is the prosecutions burden to prove every element of an offense and everyone is presumed innocent until proven guilty. Prior to this case, I felt the law permitting a blood or breath test result admissible by affidavit essentially shifted ...

This study investigated whether or not there was an overall difference in the pulmonary oxidative marker, 8-isoprostane (PGF2-a), found in exhaled breath condensate, during pregnancy versus the non-pregnant state. The utility of this information was important secondary to the effect of maternal asthma on pregnancy and outcome, as it has been demonstrated in past studies that overall pregnant females with asthma have been shown to have an increased risk of exacerbation requiring medical intervention.The primary goal of this study sought to determine if there is a difference in PGF2a levels in the exhaled breath condensate of pregnant versus non-pregnant females. In order to achieve this goal a cross-sectional study was performed consisting of two groups and were compared to one another. A group of 16 healthy, non-pregnant females aged 18-35 years old was compared to a group of 6 healthy, pregnant females in their third trimester of pregnancy. Both groups exhaled breath condensate was collected and 8
A simple breath test can be done in the office to test for bacterial overgrowth. The overproduction of gasses such as hydrogen is absorbed through the bloodstream and excreted through the lungs. After you blow through a special device, the Hydrogen Breath Test can allow us to measure the amount of hydrogen in your lungs. An elevated hydrogen level alerts us to the possibility of bacterial overgrowth.. You must fast for 12 hours before your appointment. We ask that you take your medications as directed with a small sip of water the morning of the procedure. Please advise your health care provider if you are diabetic or if you have been on antibiotics within the last two weeks. You will be given a small amount of lactulose to drink. A random breath test will then be obtained and you will be asked to return to the office in one hour. Breath tests will then be obtained at 15 minute intervals over a three hour period. (You will need to allow for ample time to complete this test.) Detailed ...

This Bill amends the Land Transport Act 1998 to broaden the circumstances where a positive evidential breath test is admissible evidence in a prosecution under the Act. Under present law a positive evidential breath test is not admissible in evidence if the suspect has elected to have a blood test. The Act assumes that the blood test will be available as evidence for any prosecution. The Bill will amend section 77 to provide that where a suspect has elected to have a blood test but blood is unable to be drawn for any reason, the prior evidential breath test is admissible in evidence in a prosecution for an offence against any of sections 56 to 62. ...
The objective of this study is to determine if the action of the drug called clopidogrel, that you will start taking, will be decreased by another drug called atorvastatin, that you will also start taking. Clopidogrel is an oral antiplatelet agent that has been shown to prevent strokes and heart attacks. Atorvastatin is a cholesterol lowering agent.. Twenty adults 18-75 years of age requiring cholesterol-lowering agent and antiplatelet agent therapy will be recruited for this study during their cardiology clinic visitation. In one group, antiplatelet agent (clopidogrel) regimen will be administered first, then followed by cholesterol-lowering medication (atorvastatin). In the second group, atorvastatin will be administered first, followed by clopidogrel.. A new test called the erythromycin breath test will be administered to you three times during the study to measure how your liver will metabolize these drugs. Blood samples will also be obtained to assess platelet function. The criteria for ...

The GEBT is measured over a 4-hour time cycle. Detailed administration instructions can be found in Table 1. Multiple breath samples are obtained from the patient; sampling should be performed subsequent to an 8-hour fast. After providing multiple premeal breath samples (Table 2), the patient consumes the standard GEBT meal consisting of pasteurized scrambled egg mix containing a dose of 43 mg of 13C-Spirulina, 6 saltine crackers, and 6 ounces of potable water.5 The 13C-Spirulina is eventually passed through the GI tract to the intestines; it is in the intestines that the Spirulina is absorbed and metabolized to the 13CO2 expired in the breath. Single postmeal breath samples are subsequently collected (Table 2) at 45, 90, 120, 150, 180, and 240 minutes from the end of test-meal consumption. The post-meal breath samples are transmitted to a laboratory for assessment of 13CO2/12CO2 in each sample. By measuring the change in this ratio over time as compared to the pre-meal value, the rate of 13CO2 ...

An early and accurate diagnosis can be very important for cancer sufferers. Having the cancer spotted early is one of the things that can help put a cancer sufferer in as strong of position as possible to fight the cancer. Thus, finding methods to help with the diagnosing of cancer is a remarkably important research objective.. A recent study indicates that a rather unconventional, and simple, method may be able to help doctors when it comes to diagnosing lung cancer.. In the study, Italian researchers had the participants (some of who had lung cancer and others of who did not) undergo a breath temperature test. The test simply involved the use of a breath thermometer.. The researchers made a rather surprising finding. They found that breath temperatures were higher among the individuals with lung cancer than they were for those without the cancer. They further found that breath temperature tended to go up as a persons lung cancer became more developed.. Based on these findings, the researchers ...

Breath gas contains a range of marker gases that can be associated with disease and metabolism. For instance, the monitoring of breath H2 is useful for measurement of orocecal transit time, colonic fermentation, abnormal fermentation and irritable bowel syndrome.
Health care monitoring is an enormous field of research that has great potential to solve many problems in human life. In recent years, non-invasive health monitoring has become a prerequisite for early diagnosis of various diseases such as lung cancer, oxidative stress, diabetes, to enable the prompt treatment and screening of crucial chemicals. Although analyzing of exhaled breath has been correlated with advanced analytical techniques such as gas chromatography and infrared spectroscopy, breath analyzing biosensing systems offer a cost-effective, sensitive platform for a straightforward analysis. However, current non-invasive sensing strategies have been lacking in practicality in terms of the design and usage, on-site ability and accessibility. This review will critically discuss current commercialized breath analyzers, the recent achievements for the use of the detection towards chemical and biological substances from exhaled breath as non-invasive sensing systems including ...

The Olympian. Evidence in drunken driving cases across the state are likely to be challenged because of questions about the states toxicology lab managers role in checking breath analyzers, defense attorneys say.. The Washington State Patrol and prosecutors say the former managers failure to personally check batches of a solution used in breath analyzers has no effect on the machines accuracy, because other analysts did test the solution.. But the lab manager, Ann Marie Gordon, signed an undetermined number of legal certificates since 2002 saying she had checked the solution. It is used by police officers to confirm their machines are accurately measuring the amount of alcohol in a persons breath.. Defense attorneys across the state now are going to challenge the admissibility of the breath tests, said Bill Bowman, president-elect of the Washington Association of Criminal Defense Lawyers.. The bigger implication, in my opinion, is to the credibility of the state, he added, explaining ...

For the test developed by postdoctoral researcher Eva Borras, Davis and colleagues, subjects breathe normally into a specialized collection device. Droplets in breath condense and are stored in a freezer until testing. Davis’ lab uses mass spectrometry to identify compounds in the samples. The researchers tested the technique in a small group of patients receiving infusions of pain medications including morphine and hydromorphone, or oral doses of oxycodone, at the UC Davis Medical Center. They were therefore able to compare opioid metabolites in breath with both blood samples and the doses given to patients. “We can see both the original drug and metabolites in exhaled breath,� Davis said. Fully validating the breath test will require more data from larger groups of patients, she said. Davis’ laboratory is working toward real-time, bedside testing. Other authors on the paper include graduate student Andy Cheng, UC Davis forensic science program; Ted Wun, Department of ...

Do you have bad breath? It may not be because you ate too much garlic, it may be because youre SICK. Its one of the main indicators of gum disease, but bad breath has a more serious side too. If your breath smells like nitric oxide, you could have asthma. If it smells like carbon, you could have stomach ulcers. Doctors can recognize telltale patterns in the way your breath smells that will make them investigate whether or not you have lung cancer. Acetone breath indicate diabetes from ketosis (which means youre not absorbing enough glucose). Ammonia breath could indicate kidney disease. People with liver disease have breath with high levels of carbon dioxide. Too much bacteria in your intestines (which can lead to irritable bowel syndrom, or IBS) produces breath with elevated hydrogen levels (youll need a chemist to measure these last two). Certain chemicals in your breath can also indicate that your heart transplant is being rejected. In the October 9th edition of the Wall Street Journal, ...
Breath hydrogen excretion over a period of three hours was measured to evaluate carbohydrate malassimilation in healthy cats treated orally with antibiotics. Both an absorbable carbohydrate (xylose) and a non-absorbable carbohydrate (lactulose) were administered during the tests to evaluate the changes in the intestinal mucosa and the population of bacteria within the intestinal lumen. Overall, the effects of oxytetracycline and metronidazole on breath hydrogen excretion were not significantly different. However, the treatment effect with an antibiotic did significantly change breath hydrogen excretion after xylose administration (P<0.05) within groups. Similarly, with each antibiotic, breath hydrogen excretion was affected significantly (P<0.001) by the time after the administration of the carbohydrate. Treatment with each antibiotic also interacted significantly with this time effect (P<0.05) within groups. After lactulose administration, there was a trend within groups for the ...
In this work, various parameters that influence the ionic content and pH of exhaled breath condensate in terms of the non-invasive diagnosis of gastroesophageal reflux disease were studied. Exhaled breath condensate samples were collected using a miniature and inexpensive sampling device. Capillary electrophoresis with contactless conductometric detection was used to monitor the ionic content of exhaled breath condensate. Background electrolyte composed of 20 mM of 2-(N-Morpholino)ethanesulfonic acid, 20 mM of L-Histidine, 2 mM of 18-Crown-6 and 30 mu M of cetyltrimethylammonium bromide facilitated the rapid separation of anions and cations, both in less than 2 minutes. The possibility of contamination of the exhaled breath condensate by saliva is discussed in detail. The day-to-day repeatability (n=5) of the ionic content and pH of the exhaled breath condensate was studied and was satisfactory, reflecting mainly the physiological variability ...
Hydrogen gas in the body is produced from intestinal bacteria. Bacteria, normally in the large intestine, produce hydrogen through fermentation of carbohydrates - such as lactose, lactulose, and fructose which are substrates given for the hydrogen breath test. Some of the hydrogen produced by bacteria is absorbed by intestinal mucosa whereby it enters the blood stream and is transported to the lungs. Hydrogen is then exhaled by the lungs by normal breathing. This is collected in the bag for subsequent analysis.. In small intestinal bacterial overgrowth, the small intestinal bacteria metabolize the lactulose given and produce an early rise in the breath hydrogen.. In lactose intolerance, the individual has a deficiency in lactase, the enzyme that breaks down lactose. Normally, lactose is broken down in the small intestine by lactase and very little lactose reaches the large intestine where the bacteria break it down to produce hydrogen. In lactose intolerance (lactase deficiency), the ingested ...

Clinical manifestations of lactase (LCT) deficiency include intestinal and extra-intestinal symptoms. Lactose hydrogen breath test (H2-BT) is considered the gold standard to evaluate LCT deficiency (LD). Recently, the single-nucleotide polymorphism C/T(-13910) has been associated with LD. The objectives of the present study were to evaluate the agreement between genetic testing of LCT C/T(-13910) and lactose H2-BT, and the diagnostic value of extended symptom assessment. Of the 201 patients included in the study, 194 (139 females; mean age 38, range 17-79 years, and 55 males, mean age 38, range 18-68 years) patients with clinical suspicion of LD underwent a 3-4 h H2-BT and genetic testing for LCT C/T(-13910). Patients rated five intestinal and four extra-intestinal symptoms during the H2-BT and then at home for the following 48 h. Declaring H2-BT as the gold standard, the CC(-13910) genotype had a sensitivity of 97% and a specificity of 95% with a κ of 0.9 in diagnosing LCT deficiency. Patients ...

The erythromycin breath test (ERMBT) is a method used to measure metabolism (oxidation and elimination from the system) by a part of the cytochrome P450 system. Erythromycin is tagged with carbon-14 and given as an intravenous injection; after 20 minutes the subject blows up a balloon and the carbon dioxide exhaled that is tagged with carbon-14 shows the activity of the CYP3A4 isoenzyme on the erythromycin. Therefore, this activity can predict how other drugs that are metabolized by the CYP3A4 part of the cytochrome P450 system will be acted upon by a particular person. The test allows doctors to determine or predict an individuals drug treatment outcome. Will a patient develop serious or fatal side effects from a certain drug? Which foods and drugs should not be taken together? With this and other tests a physician may determine treatment outcomes in advance or study the effects of new drugs. Some patients have a congenital inability to synthesize certain enzymes, so drugs may build up to ...

SIBO is normally diagnosed by a hydrogen breath test. An individual is given a solution to drink such as lactulose and then a breath test is administered to assess the presence of gas such as methane or hydrogen. If someone had a healthy gut, there would not be either of these two gases in the breath till after 2 hours or the approximate time it would take for the lactulose to travel from the mouth to the large intestine where bacteria feed on it and release gas.. If someone has SIBO there would be a positive test within 90 minutes of drinking the lactulose since the bacteria would be higher in the gut or the small intestine.. How does SIBO occur? Many different theories abound and many link IBS (irritable bowel syndrome) with being SIBO incognito. Is it due to overuse of antibiotics, diet balance, types of food, none or all of the above?. No one exactly knows but I have my own theory.. I write blogs based on my own experiences, those of my patients and what I see on a regular basis. In the last ...

Scientists have identified the chemical fingerprints given off by specific bacteria when present in the lungs, potentially allowing for a quick and simple breath test to diagnose infections such as tuberculosis. Publishing their study today, 11 January, in IOP Publishings Journal of Breath Research, the researchers have successfully distinguished between different types of bacteria, as well as different strains of the same bacteria, in the lungs of mice by analysing the volatile organic compounds (VOCs) present in exhaled breath. It is hoped that a simple breath test could reduce the diagnosis time of lung infections from days and weeks to just minutes. Co-author of the paper, Jane Hill, from the University of Vermont, said:

Lipid peroxidation plays an important role in the pathogenesis of pneumoconiosis. Volatile organic compounds (VOCs) generated from lipid peroxidation might be used to detect pneumoconiosis. The objective of this study was to develop a breath test for pneumoconiosis. A case-control study was designed. Breath and ambient air were analysed by gas chromatography/mass spectrometry. After blank correction to prevent contamination from ambient air, we used canonical discriminant analysis (CDA) to assess the discrimination accuracy and principal component analysis (PCA) to generate a prediction score. The prediction accuracy was calculated and validated using the International Classification of Radiographs of the Pneumoconiosis criteria combined with an abnormal pulmonary function test as a reference standard.

The procedure for each test (fructose, lactose, sorbitol and lactulose) is simple. You need to perform each breath test on a different day. When you attend each breath test appointment you will be given a hydrogen breathalyser type device to breathe into. This first sample is recorded, then you will be given a sugar solution to drink, after which another breath sample will be taken from you every 15-20 minutes over the next 2~3 hours. Many people complete the tests for Lactulose, Fructose, Sorbitol and Lactose within 2 hours, although some take around 3 hours. Your referring practitioner will describe which of the test sugars (Fructose, Sorbitol or Lactose - or any combination of these) you are to do. However, a practice test, (a Lactulose test) must be performed prior to any of these test sugars, to make sure you produce enough hydrogen gas. If you are a low- or non-hydrogen producer with Lactulose, you will be changed from the breathalyser device to inflatable bags during the course of your ...

Alcohol may stay in our breath which d epending on the alcohol degree, the duration of alcohol leaving in your breath varies. For instance, to detect alcohol in your breath, a Breathalyser is used. They can detect alcohol in your breath for up to 24 hours after consumption. On average, the liver can metabolize 1 standard drink per hour for men, or about 0.015g/100mL/hour (i.e., a reduction of blood alcohol level, or BAC, by 0.015 per hour). Coffee, cold showers, and sleeping it off will not sober you up. Mouth Wash. The bloodstream moves the alcohol throughout your body, and the smell of it on your breath originates from your lungs. Alcohol can leave the body through the breath, perspiration and urine, though a majority will be broken down with the metabolism. Time is the only thing that can lower your BAC, so be smart about your drinking and always have a backup plan to get home. Your breath alcohol level has a direct relation to the amount of alcohol in your blood. Alcohol has two exit paths ...

It is erroneous to think that by refusing a breath test you will avoid DWI charges just because there is no record of your BAC. In fact, the prosecution can argue that you refused the test because you knew that you were intoxicated above the legal limit. In other words, you CAN be convicted for DWI without evidence from a breathalyzer test.. While the penalties in a refusal case are enhanced and defending these cases is more complicated, refusals can be beaten. The State must prove that probable cause existed to arrest, that you were asked to provide a breath sample, that you refused to provide a sample, and that you were advised of penalties for refusing.. In a case like this, it is in your best interest to consult an attorney who is experienced in defending refusals immediately.. ...
Chemical Tests: Blood & Breath Once someone is placed under arrest for driving under the influence of alcohol or drugs, they are told that they have a choice of chemical tests that they must take. According to Californias implied consent law, the person arrested has a choice of taking a blood or breath test if the arrest is alcohol related, or taking a blood or urine test if the arrest is drug related. REMEMBER, BEFORE YOU ARE PLACED UNDER ARREST, YOU DO NOT HAVE TO TAKE THE BREATH TEST ON THE SIDE OF THE ROAD. It is only when you are arrested that the implied consent law comes into effect…at which point you have your choice of either blood or breath test to be given at the police station. There is no right to consult with a lawyer prior to taking the chemical test.. A good lawyer will make sure that the chemical test was properly done, and if not, a good lawyer will use that to try and prevent his client from getting a DUI. Title 17 of the California Code of Regulations, sets out the ...

Anaerobic bacterial metabolism in the colon produces hydrogen, methane, volatile fatty acids and carbon dioxide. Hydrogen and methane are excreted in flatus and the expired breath. Investigations in this Thesis attempted to identify factors which may influence methane excretion in man and explain why all subjects do not excrete methane. The proportions of methane producing subjects in two healthy populations studied in Edinburgh were 33% and 70% respectively. Age and sex did not significantly alter methane excretion. Dietary intakes, faecal components and bowel function were found to be similar in methane producing and non-methane producing subjects. An association was found between the ingestion of the pentose fraction of non-cellulosic polysaccharides and the concentration of breath methane in methane producing subjects. This association may be the result of a steady metabolic state in the caecum. Ingestion of pentose monomers D(+) xylose and L(+) arabinose increased methane excretion, in ...
Now we can add yet another breath testing challenge.. Our office (The McShane Firm, LLC) of Harrisburg, Pennsylvania filed a systematic challenge to the testing and calibration regime as it is currently practiced in the Commonwealth of Pennsylvania.

Are Breath Tests Accurate?. Keep in mind that a police-administered breath test creates an estimate of the amount of alcohol that is in your breath. Like all estimates, it can be accurate or inaccurate, depending upon the circumstance. However, breath alcohol levels do not necessarily accurately reflect blood alcohol levels. In other words, a sample of breath with a certain amount of alcohol in it may be accurately analyzed for the amount of alcohol in the specimen of breath, but it may bear little relationship to the amount of alcohol in the blood. This is because of several factors:. - The Intoxilyzer 8000, which is the machine used in Arizona, is acknowledged to have up to a 10% random error factor by the government ...

Helicobacter pylori is a bacterium linked with duodenal and gastric ulcers and is associated with an increased incidence of gastric cancers. Ingestion of the bacteria can cause acute gastritis with associated nausea and vomiting and eventually chronic ulceration.(9) Elimination of the infection with a combination of the proton pump inhibitor omeprazole and clarithromycin, a macrolide antibiotic, can achieve a 70-80% cure rate and alters the course of the disease from a chronic, relapsing condition to a cure.(10) The best test for identification of H pylori and for confirmation of eradication is the (13)C breath test - this is a carbon-tagged breath test that depends on urease degradation of urea to produce tagged carbon, which then appears in exhaled breath. This test can be performed in the treatment room and is available on prescription.(1) ...

A great defense that our drunk driving trial lawyers have used with great success in Oakland County is to argue that the defendant had alcohol in their mouth when they blew into the Datamaster DMT machine. This argument is far from far-fetched as most of us have probably experienced the feeling that you have thrown-up into your mouth. Not to be disgusting, but when that happens, you can taste the contents of your stomach. When you consume alcohol and this happens, the reason why you can taste your last beer is because your last beer is actually coming back up into your mouth. And when there is alcohol in your mouth, theres a good chance that the result of the breath test machine is not correct.. This phenomenon is so important that the Michigan State Police have taken numerous protective measures in the Administrative Rules in order to prevent this from happening. The Administrative Rules require that officers actually sit there and watch the suspect for fifteen minutes prior to the ...
If you are stopped for a traffic violation and the officer suspects you of DUI, he or she might ask you to take a preliminary breath test (PBT). Can you refuse?. Under Illinois statute, if an officer has a reasonable suspicion to believe that you are driving under the influence, the officer may request that you take the PBT. An officer may use the PBT to determine whether to ask you to take further tests. However, you may refuse, and there are no penalties for refusing this particular test. (See People v Guiterrez.). Whether you should refuse the field sobriety tests and/or a breathalyzer is a complicated matter. (See our related blog To Breathe or Not to Breathe: Taking the Breathalyzer.) Refusing the tests can make it harder for the state to convict you. However, there are penalties to refusing. For example, your drivers license may be suspended for a much longer time period.. With the PBT, the results are generally not admissible in criminal court because of state certification requirements ...

Spontaneous epistaxis is more common in the elderly as the nasal mucosa (lining) becomes dry and thin and blood pressure tends to be higher. The elderly are also more prone to prolonged nose bleeds as their blood vessels are less able to constrict and control the bleeding..

  • What is the hydrogen breath test? (
  • The hydrogen breath test is a test that uses the measurement of hydrogen in the breath to diagnose several conditions that cause gastrointestinal symptoms. (
  • The hydrogen-containing blood travels to the lungs where the hydrogen is released and exhaled in the breath where it can be measured. (
  • When is hydrogen breath testing used? (
  • Hydrogen breath testing is used in the diagnosis of three conditions. (
  • The second condition for which hydrogen breath testing is used is for diagnosing bacterial overgrowth of the small bowel, a condition in which larger-than-normal numbers of colonic bacteria are present in the small intestine. (
  • The third condition for which hydrogen breath testing is used is for diagnosing rapid passage of food through the small intestine. (
  • How does hydrogen breath testing work? (
  • As previously discussed, some of the hydrogen gas is absorbed by the colon into the blood and is eliminated in the breath where it can be measured. (
  • For example, if an individual digests and absorbs the sugar in milk (lactose) normally, then none of the lactose that is given for the lactose hydrogen breath test reaches the colon, and no increase in the concentration of hydrogen in the breath is seen during the breath test. (
  • They instead test of any molecule having a carbon/hydrogen bond. (
  • Physicians can diagnose lactose intolerance with a test that identifies abnormally high levels of hydrogen in the breath produced by gut bacteria that gobble lactose when the body fails to break down the milk sugar on its own. (
  • Here we report the prevalence of lactose intolerance in a double-blind placebo study.The LCT C>T-13910 variant was genotyped by RT-PCR in 121 volunteers and lactose malabsorption was assessed using the hydrogen breath test (HBT) after consuming 25 g of lactose . (
  • This pilot study aimed to determine whether raw milk reduces lactose malabsorption and/or lactose intolerance symptoms relative to pasteurized milk.We performed a crossover trial involving 16 adults with self-reported lactose intolerance and lactose malabsorption confirmed by hydrogen (H2) breath testing . (
  • Correlation between symptoms developed after the oral ingestion of 50 g lactose and results of hydrogen breath testing for lactose intolerance. (
  • not previously undergo a diagnostic algorithm in full, for instance, one that may consist of a glucose breath hydrogen test and an empiric attempt of a dietary switch to galactomin, we suggest that molecular genotyping of such patients should only follow such appropriate clinical evaluation. (
  • Hydrogen breath test - it is becoming more and more common for people to undertake a medical test for clinical diagnosis of dietary disabilities such as fructose intolerance, fructose malabsorption, lactose intolerance and lactulose intolerance. (
  • A hydrogen breath test (or HBT) is used as a diagnostic tool for small intestine bacterial overgrowth and carbohydrate malabsorption, such as lactose, fructose, and sorbitol malabsorption. (
  • Hydrogen breath tests are based on the fact that there is no source for hydrogen gas in humans other than bacterial metabolism of carbohydrates. (
  • Even though the test is normally known as a "hydrogen" breath test, some physicians may also test for methane in addition to hydrogen. (
  • In addition to hydrogen and methane, some facilities also utilize carbon dioxide (CO2) in the patient's breath to determine if the breath samples that are being analyzed are contaminated (either with room air or bronchial dead space air). (
  • Tests vary from country to country, so the following information is provided as a rough guide to typical uses of the hydrogen breath test: Fructose malabsorption - the patient takes a base reading of hydrogen levels in his/her breath. (
  • The basis of the test is a failure to absorb the given sugar, which is then metabolized by bacteria that give off either hydrogen or methane. (
  • If the level of hydrogen rises above 20 ppm (parts per million) over the lowest preceding value within the test period, the patient is typically diagnosed as a fructose malabsorber. (
  • Lactose malabsorption - the patient takes a base reading of hydrogen levels in his/her breath. (
  • Positive diagnosis for a lactulose SIBO breath test - typically positive if the patient produces approximately 20 ppm of hydrogen and/or methane within the first 60-90 minutes (indicates bacteria in the small intestine), followed by a much larger peak (colonic response). (
  • Stream Diagnostics is Australia's leading and mostexperienced provider of hydrogen/methane breath testing for Fructose, Lactoseand Sorbitol malabsorption and Small Intestine Bacterial Overgrowth (SIBO). (
