Overnight storage of blood in ACD tubes at 4{degrees}C increases NK cell fraction in peripheral blood mononuclear cells.  

PubMed

A considerable variabilility in the effects of sample handling on NK cytotoxicity has been observed. Using flow cytometry, NK cytotoxicity assays and lymphocyte subset analysis of Ficoll-Hypaque-separated peripheral blood mononuclear cells (PBMCs) isolated from whole blood stored under various conditions were performed. The NK cytotoxicity of samples in heparin tubes stored overnight at 4 and 22°C, as well as at 22°C in acid citrate dextrose (ACD) tubes, was lower than that of a fresh sample. However, the NK cytotoxicity of samples in an ACD tube stored at 4°C was similar to that of a fresh sample. Based on lymphocyte subset analysis, samples in an ACD tube stored at 4°C showed a lower percentage of CD3+ T cells and a higher percentage of CD16/56+ NK cells compared to samples stored under other conditions. The NK cytotoxicity of fresh samples and samples in ACD tubes stored in a Styrofoam cooler box did not differ significantly; however, the differences were inconsistent. Overnight storage of peripheral blood in ACD tubes at 4°C is optimum for retention of NK cytotoxicity, the level of which is similar to that of fresh blood. This may be associated with an increased NK-cell fraction in Ficoll-Hypaque-separated PBMCs after overnight storage. PMID:23884220

Effects of overnight fasting on working memory-related brain network: An fMRI study.  

PubMed

Glucose metabolism serves as the central source of energy for the human brain. Little is known about the effects of blood glucose level (BGL) on higher-order cognitive functions within a physiological range (e.g., after overnight fasting). In this randomized, placebo-controlled, double blind study, we assessed the impact of overnight fasting (14h) on brain activation during a working memory task. We sought to mimic BGLs that occur naturally in healthy humans after overnight fasting. After standardized periods of food restriction, 40 (20 male) healthy participants were randomly assigned to receive either glucagon to balance the BGL or placebo (NaCl). A parametric fMRI paradigm, including 2-back and 0-back tasks, was used. Subclinically low BGL following overnight fasting was found to be linked to reduced involvement of the bilateral dorsal midline thalamus and the bilateral basal ganglia, suggesting high sensitivity of those regions to minimal changes in BGLs. Our results indicate that overnight fasting leads to physiologically low levels of glucose, impacting brain activation during working memory tasks even when there are no differences in cognitive performance.

Ambulatory laparoscopic cholecystectomy: An audit of day case vs overnight surgery at a community hospital in Japan  

PubMed Central

AIM: To evaluate the applicability and safety of ambulatory laparoscopic cholecystectomy (LC) and to compare day case and overnight stay LC. METHODS: Data were collected retrospectively and consecutively for day case and overnight stay LC patients from July 1, 2009 to April 30, 2011. Outcomes were analyzed for patient demographics, operation time, blood loss during operation and frequency and reasons for unexpected or prolonged hospitalization in each group. RESULTS: There was no hospital mortality and no patient was readmitted with serious morbidity after discharge. 50 patients received a day case LC and 19 had an overnight stay LC. There was a significant difference in age between both groups (P < 0.02). There were no significant differences between the day case LC performed (n = 41) and failed (n = 9) groups and between the day case LC performed and the one night stay LC (n = 12) groups. There was a significant difference in age between the one night stay and more nights stay LC groups (P < 0.05). Thus, elderly patients showed a tendency to like to stay in hospital rather than being a day case. The proportion of unexpected or prolonged hospitalization was not significantly different between the day case and overnight stay LC groups, when the patient’s request was excluded. CONCLUSION: Day case LC can be performed with a low rate of complications. In overnight stay patients, there are many who could be performed safely as a day case. Moreover, we need to take special care to treat elderly patients. PMID:23493831

Overnight Custody Arrangements, Attachment, and Adjustment Among Very Young Children  

PubMed Central

Large numbers of infants and toddlers have parents who live apart due to separation, divorce, or nonmarital/noncohabiting child-bearing, yet this important topic, especially the controversial issue of frequent overnights with nonresidential parents, is understudied. The authors analyzed data from the Fragile Families and Child Wellbeing Study, a longitudinal investigation of children born to primarily low-income, racial/ethnic minority parents that is representative of 20 U.S. cities with populations over 200,000. Among young children whose parents lived apart, 6.9% of infants (birth to age 1) and 5.3% of toddlers (ages 1 to 3) spent an average of at least 1 overnight per week with their nonresident parent. An additional 6.8% of toddlers spent 35% – 70% of overnights with nonresident parents. Frequent overnights were significantly associated with attachment insecurity among infants, but the relationship was less clear for toddlers. Attachment insecurity predicted adjustment problems at ages 3 and 5, but frequent overnights were not directly linked with adjustment problems at older ages.

Variations in Physician Interpretation of Overnight Pulse Oximetry Monitoring  

PubMed Central

Background Overnight pulse oximetry is commonly used for hypoxemia evaluation in patients with COPD and sleep-disordered breathing. There is little information regarding its impact on physician decision making, and therefore an important measure of its clinical utility is untested and unknown. The aim of this study was to describe physician interpretation, use, and opinions regarding overnight pulse oximetry. Methods Forty-one pulmonary physicians and fellows participated in structured interviews consisting of three oximetry record interpretations, oral responses to a standard question set, and a questionnaire. Qualitative data were analyzed using an open coding process. Quantitative data were assessed for distributions. Results Four measures were consistently used by the majority of physicians in record interpretation: background information, arterial oxygen saturation measured by pulse oximetry (SpO2) waveform and pattern, and time spent with SpO2 < 90%. An additional 10 measures were consistently used by 5 to 46% of physicians. No interpretation generated a recommendation with > 60% consensus. There was a wide range of opinions on important matters related to this test, including test utility, indications, variables considered most important for interpretation, and criteria for nocturnal oxygen prescription. Forty-one physicians provided 35 different opinions on when nocturnal supplemental oxygen should be initiated. Conclusions The variation in physician interpretation, use, and opinions regarding overnight pulse oximetry calls into question its clinical utility and underscores a need for standardization of presentation, training, and interpretation.

Oxidative stress is involved in fatigue induced by overnight deskwork as assessed by increase in plasma tocopherylhydroqinone and hydroxycholesterol.  

PubMed

In this study, we examined the relationship between fatigue and plasma concentrations of antioxidants and lipid peroxidation products. Fourteen healthy volunteers performed overnight desk work for 18h then took a nap for 4h. Participants answered questionnaires of subjective symptoms of fatigue (QSSF) and completed a self-assessment of fatigue using a visual analog scale (VAS). At each test time, they underwent a critical flicker frequency (CFF) test and blood samples were collected. Plasma levels of ?-tocopherol (?T) decreased and ?-tocopherylquinone (?TQ), the oxidation product of ?T, increased. The ratio of 7?-hydroxycholesterol (7?-OHCh), the oxidation product of cholesterol, against total cholesterol increased until the end of experiment. ?TQ levels correlated with VAS and QSSF scores. The ratio of 7?-OHCh to total cholesterol and the value of CFF showed a significant correlation. From these results, plasma levels of ?TQ and 7?-OHCh are useful and objective indicators of fatigue induced by overnight deskwork. PMID:24121154

The loss of CD34+ cells in peripheral hematopoietic stem cell products cryopreserved by non-controlled rate freezing and stored at -80?°C after overnight storage.  

PubMed

Although peripheral blood stem cell (PBSC) products cryopreserved by non-controlled rate freezing and stored at -80?°C after overnight storage are used frequently, data regarding the rate of loss of CD34+ cells in these products are limited. In this prospective study, CD34+ cells were counted at three (fresh, post-overnight and post-thaw) points in 83 PBSC products from 41 patients by flow cytometry. Compared to fresh products, the mean losses of post-overnight and post-thaw total CD34+ cells are 16.3% and 38.4% (p?=?0.02), and the mean losses of post-overnight and post-thaw viable CD34+ cells are 16.5% and 48.5%, respectively (p?

Changes in overnight arterial oxygen saturation after mandibular setback.  

PubMed

Mandibular setback reduces space in the pharyngeal airway, and it has been suggested that it might induce sleep-disordered breathing. We report on its effects on space in the pharyngeal airway and respiratory function during sleep. We studied 78 patients (29 men and 49 women) in whom skeletal class III malocclusions had been corrected. The mean (range) age at operation was 24 (16-38) years and body mass index (BMI) 21.4 (16.1-30 .9)kg/m(2). Morphological changes were evaluated on lateral cephalograms taken three times: preoperatively, a few days postoperatively, and more than 6 months postoperatively. Overnight arterial oxygen saturation (SpO2) was measured by pulse oximetry 6 times: preoperatively, and on days 1, 3, 5, and 7, and 6 months postoperatively; oximetric indices were calculated. Those immediately after mandibular setback were significantly worse than those preoperatively, although they gradually improved. There were positive correlations between BMI and oximetric indices, and little association between changes in mandibular position and oximetric indices. There was no evidence of sleep-disordered breathing 6 months after mandibular setback because most patients adapt to the new environment for respiratory function during sleep. However, some (particularly obese) patients may develop sleep-disordered breathing just after mandibular setback. In such patients attention should be paid to respiratory function during sleep in the immediate postoperative period, and careful postoperative follow-up is needed. PMID:22853977

311 temperature during overnight holding in meiosis inhibitor-free medium affects chromatin configuration and meiotic resumption in equine oocytes.  

PubMed

Immature equine oocytes may be held overnight in an Earle's/Hanks' M199-based medium in the absence of meiotic inhibitors (EH medium) to schedule the onset of in vitro maturation. Holding in EH has been shown not to affect meiotic or developmental competence of equine oocytes (Choi et al. 2006 Theriogenology 66, 955-963). However, no studies have been performed to identify the mode by which this medium suppresses meiosis. We hypothesised that holding temperature may affect oocyte meiotic arrest. The effect of 3 holding temperatures (25, 30, 38°C) on chromatin status was investigated after Hoechst 33258 staining (Hinrichs et al. 2005 Biol. Reprod. 72, 1142-1150). Oocytes were recovered by scraping of follicles from slaughterhouse-derived ovaries. Data were analysed by Chi-squared test and one-way ANOVA followed by Dunn's or Holm-Sidak Multiple Comparison methods. A level of P<0.05 was considered significant. There were no significant differences in chromatin configuration between oocytes held overnight at 25°C (25°C-held) and controls (immediately-fixed oocytes); the proportion of oocytes showing meiotic resumption was 1/27, 4% and 0/26, 0%, respectively (not significant, NS). In contrast, holding at higher temperature significantly increased meiosis resumption (14/38, 37% and 14/28, 50%, at 30 and 38°C, respectively; P<0.01) and reduced the proportion of oocytes showing the most meiotically-competent germinal-vesicle (GV) configuration (condensed chromatin, CC; 24 to 29% v. 65 to 70% for control and 25°C-held, respectively; P<0.05). Based on these results, a subsequent experiment was performed in which oocyte meiotic stage and mitochondrial (mt) potential of 25°C-held (n=29) and control (n=36) oocytes was evaluated. Nuclear chromatin, mt activity (MitoTracker orange), intracellular reactive oxygen species (ROS) levels (2',7'-dichlorodihydrofluorescein diacetate, DCDHFDA), and mt/ROS colocalization (Pearson's coefficient) were analysed by epifluoscence and confocal microscopy (Martino et al. 2012 Fertil. Steril. 97, 720-728). Meiotic arrest after EH treatment at 25°C was confirmed (0/29, 0% v. 5/36, 14% for meiotic resumption in 25°C-held and controls, respectively; NS). At any GV stage, 25°C-held treatment had no effect on mt activity, ROS levels, or mt/ROS colocalization. For example, in CC oocytes, values for control and 25°C-held, respectively, were: MitoTracker, 547.8±499.5 v. 722.9±390.3; DCF fluorescence intensity, 278.5±179.3 v. 378±185, and mt/ROS colocalization, 0.5±0.1 v. 0.5±0.2; these were not significantly different (NS). In conclusion, EH holding at 25°C maintains meiotic arrest, viability, and mt potential of equine oocytes. PMID:25472359

The Overnight Effect of Dietary Energy Balance on Postprandial Plasma Free Amino Acid (PFAA) Profiles in Japanese Adult Men  

PubMed Central

The plasma free amino acid (PFAA) profile is affected by various nutritional conditions, such as the dietary energy balance. Regarding the clinical use of PFAA profiling, it is of concern that differences in food ingestion patterns may generate systematic errors in a plasma amino acid profile and constitute a confounding factor in assessment. In this study, the overnight impact of the dietary energy balance on the postprandial plasma amino acid profile was investigated to elucidate in particular the effects of high protein meals typical in Japanese cuisine. We conducted diet-controlled, crossover trials in eleven healthy male volunteers aged 40–61 y. They consumed either a normal meal (meal N) or high protein meal (meal H) at dinner. Forearm venous blood was collected, and plasma amino acid concentrations were measured before dinner and the next morning. We found that a high protein meal in the evening that contained 40% energy would significantly increase the PFAA concentration the next morning, even more than 12 hours after the meal. Among amino acids, the most significant difference was observed in the branched-chain amino acids (BCAAs) and in some urea-cycle related compounds. If the subject consumed the high protein diet at dinner, the PFAA profile after overnight fasting might be still affected by the meal even 12 hours after the meal, suggesting that the PFAA profile does not reflect the subject's health condition, but rather the acute effect of high protein ingestion.

Robust overnight monitoring of human vital signs by a non-contact respiration and heartbeat detector.  

PubMed

A positive answer is given to the question intrigued by our previous work reported in EMBC 2005: whether it is possible for a non-contact physiological movement detector to detect vital signs from four sides of a human body. In addition to the proof from measured data, theoretical analysis confirms the surprising advantage of detection from the back of the body. Based on this observation, a non-contact system was set up to perform overnight monitoring of vital signs using low power radio waves. Measurement data is presented and analyzed. The challenges and key technologies that improved the performance of our system for overnight monitoring are discussed. PMID:17946100

Overnight Fasting Regulates Inhibitory Tone to Cholinergic Neurons of the Dorsomedial Nucleus of the Hypothalamus  

PubMed Central

The dorsomedial nucleus of the hypothalamus (DMH) contributes to the regulation of overall energy homeostasis by modulating energy intake as well as energy expenditure. Despite the importance of the DMH in the control of energy balance, DMH-specific genetic markers or neuronal subtypes are poorly defined. Here we demonstrate the presence of cholinergic neurons in the DMH using genetically modified mice that express enhanced green florescent protein (eGFP) selectively in choline acetyltransferase (Chat)-neurons. Overnight food deprivation increases the activity of DMH cholinergic neurons, as shown by induction of fos protein and a significant shift in the baseline resting membrane potential. DMH cholinergic neurons receive both glutamatergic and GABAergic synaptic input, but the activation of these neurons by an overnight fast is due entirely to decreased inhibitory tone. The decreased inhibition is associated with decreased frequency and amplitude of GABAergic synaptic currents in the cholinergic DMH neurons, while glutamatergic synaptic transmission is not altered. As neither the frequency nor amplitude of miniature GABAergic or glutamatergic postsynaptic currents is affected by overnight food deprivation, the fasting-induced decrease in inhibitory tone to cholinergic neurons is dependent on superthreshold activity of GABAergic inputs. This study reveals that cholinergic neurons in the DMH readily sense the availability of nutrients and respond to overnight fasting via decreased GABAergic inhibitory tone. As such, altered synaptic as well as neuronal activity of DMH cholinergic neurons may play a critical role in the regulation of overall energy homeostasis. PMID:23585854

Crew Factors in Flight Operations 7: Psychophysiological Responses to Overnight Cargo Operations  

NASA Technical Reports Server (NTRS)

To document the psychophysiological effects of flying overnight cargo operations, 41 B-727 crew members (average age 38 yr) were monitored before, during, and after one of two typical 8-day trip patterns. During daytime layovers, the average sleep episode was 3 hr (41%) shorter than nighttime sleeps and was rated as lighter, less restorative, and poorer overall. Sleep was frequently split into several episodes and totaled 1.2 hr less per 24 hr than on pretrip days. Each trip pattern included a night off, which was an effective countermeasure against the accumulating sleep debt. The organization of sleep during daytime layovers reflected the interaction of duty timing with circadian physiology. The circadian temperature rhythm did not adapt completely to the inverted wake-rest schedule on duty days, being delayed by about 3 hr. Highest subjective fatigue and lowest activation occurred around the time of the temperature minimum. On duty days, reports of headaches increased by 400%, of congested nose by 200%, and of burning eyes by 900%. Crew members also reported eating more snacks. Compared with daytime short-haul air-transport operations, the overnight cargo trips included fewer duty and flight hours, and had longer layovers. Overnight cargo crews also averaged 5.4 yr younger than their daytime short-haul counterparts. On trips, both groups lost a comparable amount of sleep per 24 hr, but the overnight cargo crews had shorter individual sleep episodes and more broken sleep. These data clearly demonstrate that overnight cargo operations, like other night work, involve physiological disruption not found in comparable daytime operations.

Hantavirus Infections among Overnight Visitors to Yosemite National Park, California, USA, 2012  

PubMed Central

In summer 2012, an outbreak of hantavirus infections occurred among overnight visitors to Yosemite National Park in California, USA. An investigation encompassing clinical, epidemiologic, laboratory, and environmental factors identified 10 cases among residents of 3 states. Eight case-patients experienced hantavirus pulmonary syndrome, of whom 5 required intensive care with ventilatory support and 3 died. Staying overnight in a signature tent cabin (9 case-patients) was significantly associated with becoming infected with hantavirus (p<0.001). Rodent nests and tunnels were observed in the foam insulation of the cabin walls. Rodent trapping in the implicated area resulted in high trap success rate (51%), and antibodies reactive to Sin Nombre virus were detected in 10 (14%) of 73 captured deer mice. All signature tent cabins were closed and subsequently dismantled. Continuous public awareness and rodent control and exclusion are key measures in minimizing the risk for hantavirus infection in areas inhabited by deer mice. PMID:24565589

1 Treatment of eight healthy males with propranolol (80 mg twice daily) for 6 weeks resulted in a significant reduction in overnight plasma levels of prolactin and LH. 2 Plasma testosterone levels were elevated whilst GH and cortisol were unchanged by such treatment. 3 Measurement of overnight hormone levels 48 h after discontinuing treatment showed no evidence of a 'rebound' phenomenon. 4 Cortisol, GH, prolactin, and testosterone plasma levels all showed time dependent changes: propranolol treatment significantly altered the time course of cortisol but not of the other hormones. 5 The effects of chronic propranolol treatment are discussed in terms of a probable direct central action of the drug. In addition the lowered plasma prolactin levels may directly contribute to the hypotensive action of propranolol. PMID:7340886

Molecular characterization of Acanthamoeba isolated from amebic keratitis related to orthokeratology lens overnight wear  

PubMed Central

In an effort to characterize, on the molecular scale, the Acanthamoeba initially isolated from the cornea of an amoebic keratitis patient associated with overnight-wear orthokeratology lens in Korea, we conducted mitochondrial DNA restriction fragment length polymorphism, 18S rDNA sequencing, and drug sensitivity analyses on the isolate (KA/PE1). The patient was treated with polyhexamethylene biguanide, chlorhexidine and oral itraconazole, which resulted in resolution of the patient's ocular inflammation. The majority of the molecular characteristics of the KA/PE1 were determined to be identical, or quite similar, to those of A. castellanii Ma strain, which had been isolated also from amoebic keratitis. The risk of Acanthamoeba keratitis as a potential complication of overnight orthokeratology is briefly discussed. PMID:17170573

Hantavirus infections among overnight visitors to Yosemite National Park, California, USA, 2012.  

PubMed

In summer 2012, an outbreak of hantavirus infections occurred among overnight visitors to Yosemite National Park in California, USA. An investigation encompassing clinical, epidemiologic, laboratory, and environmental factors identified 10 cases among residents of 3 states. Eight case-patients experienced hantavirus pulmonary syndrome, of whom 5 required intensive care with ventilatory support and 3 died. Staying overnight in a signature tent cabin (9 case-patients) was significantly associated with becoming infected with hantavirus (p<0.001). Rodent nests and tunnels were observed in the foam insulation of the cabin walls. Rodent trapping in the implicated area resulted in high trap success rate (51%), and antibodies reactive to Sin Nombre virus were detected in 10 (14%) of 73 captured deer mice. All signature tent cabins were closed and subsequently dismantled. Continuous public awareness and rodent control and exclusion are key measures in minimizing the risk for hantavirus infection in areas inhabited by deer mice. PMID:24565589

Effectiveness of Written Hospitalist Sign-outs in Answering Overnight Inquiries  

PubMed Central

Background Hospitalists are key providers of care to medical inpatients, and sign-out is an integral part of providing safe, high quality inpatient care. There is little known about hospitalist-to-hospitalist sign-out. Objective To evaluate the quality of hospitalist/physician-extender sign-outs by assessing how well the sign-out prepares the night team for overnight events and to determine attributes of effective sign-out. Design Analysis of a written-only sign-out protocol on a non-teaching hospitalist service using prospective data collected by attending physician survey during overnight shifts. Setting Yale-New Haven Hospital (YNHH), a 966-bed, urban, academic medical center in New Haven, CT with approximately 13,700 hospitalist discharges annually. Results We recorded 124 inquiries about 96 patients during 6 days of data collection in 2012. Hospitalists referenced the sign-out for 89 (74%) inquiries, and the sign-out was considered sufficient in isolation to respond to 27 (30%) of these inquiries. Hospitalists physically saw the patient for 14 (12%) of inquiries. Nurses were the originator for most inquiries (102 [82%]). The most common inquiry topics were medications (55 [45%]), plan of care (26 [21%]) and clinical changes (26 [21%]). Ninety-five (77%) of inquiries were considered to be “somewhat” or “very” clinically important by the hospitalist. Conclusions Overall, we found that attending hospitalists rely heavily on written sign-out to address overnight inquiries, but that those sign-outs are not reliably effective. Future work to better understand the roles of written and verbal components in sign-out is needed to help improve the safety of overnight care. PMID:24132945

Overnight fluid shifts in subjects with and without obstructive sleep apnea  

PubMed Central

Objective To investigate the characteristics of baseline body fluid content and overnight fluid shifts between non-obstructive sleep apnea (non-OSA) and obstructive sleep apnea (OSA) subjects. Methods A case-controlled study was performed between February 2013 and January 2014, with 36 (18 OSA and 18 non-OSA) outpatients enrolled in this study. Polysomnographic parameters and results of body fluid were compared between the two groups. Results There were no differences in age, weight, and body mass index (BMI) between groups. Compared with the non-OSA group, OSA group had significantly higher neck circumference (NC) and fluid volume shift in the legs. OSA patients had higher left and right leg fluid indices than non-OSA subjects. There were significant correlations between apnoea-hypopnoea index and baseline fluid indices in both legs as well as the reduction in overnight change in both legs fluid volume. The increase in NC was also significantly correlated with the reduction in overnight change in both legs fluid volume, but not with the change in head and neck fluid volume. There were significant correlations between change in NC and increased fluid shifts in head and neck volume. Conclusions OSA patients had a higher baseline fluid content in both legs as compared with non-OSA subjects, which may be the basic factor with regards to fluid shifts in OSA patients. The increase in head and neck fluid shift volume did not directly correlate with the severity of OSA. PMID:25589967

Quantifying respiratory complications post-adenotonsillectomy in patients with normal or inconclusive overnight oximetry  

PubMed Central

Background Children with sleep-disordered breathing (SDB) are at risk of developing post-operative respiratory complications following adenotonsillectomy (T&A). Our goal was to describe and quantify these complications following T&A in children with clinical SDB but with a pre-operative overnight home oximetry score of “normal/inconclusive” (McGill Oximetry Score (MOS) of 1), and to determine whether these children could safely undergo surgery in peripheral hospitals or outpatient surgical centers. Methods We performed a retrospective chart review of patients 3 years and older who had T&A between 2003 and 2010 at 2 of our institution’s hospitals. To be included in the study, in addition to not having severe comorbidities, children had to have undergone an overnight home oximetry within 12 months of surgery that was normal or inconclusive (MOS of 1). This was defined as fewer than 3 episodes of oxygen desaturation below 90% and stable baseline saturation over 95%. Medical charts were reviewed for major and minor postoperative respiratory complications. The main outcome measure was post-T&A respiratory complications. Results Out of 2708 T&A patients, 231 met the inclusion criteria. No patient had a major postoperative respiratory complication requiring re-intubation or admission to the intensive care unit. Five patients (2.16%) had minor respiratory complications but only one required admission to the ward. Conclusions An overnight home oximetry that is “normal/inconclusive” (MOS of 1) can be used as a screening tool to identify patients with sleep-disordered breathing who can be safely sent to peripheral hospitals or outpatient surgical centers for T&A.

Host Cytokine Responses Induced after Overnight Stimulation with Novel M. tuberculosis Infection Phase-Dependent Antigens Show Promise as Diagnostic Candidates for TB Disease  

PubMed Central

Background We previously identified Mycobacterium tuberculosis (M.tb) antigen-induced host markers that showed promise as TB diagnostic candidates in 7-day whole blood culture supernatants. The aim of the present study was to evaluate the utility of these markers further, and cross-compare results with short-term antigen stimulated and unstimulated culture supernatants. Methods We recruited 15 culture confirmed TB cases and 15 non-TB cases from a high-TB endemic community in Cape Town, South Africa into a pilot case-control study from an on-going larger study. Blood samples collected from study participants were stimulated with 4 M.tb antigens that were previously identified as promising (ESAT6/CFP10 (early secreted), Rv2029c (latency), Rv2032 (latency) and Rv2389c (rpf)) in a 7-day or overnight culture assay. Supernatants were also collected form the standard QuantiFERON In Tube (QFT-IT) test. The levels of 26 host markers were evaluated in the three culture supernatants using the Luminex platform. Results The unstimulated levels of CRP, Serum amyloid P (SAP) and serum amyloid A (SAA) and ESAT-6/CFP-10 specific IP-10 and SAA were amongst the best discriminatory markers in all 3 assays, ascertaining TB with AUC of 72–84%. Four-marker models accurately classified up to 92%, 100% and 100% of study participants in the overnight, 7-day and Quantiferon culture supernatants, respectively, after leave-one-out cross validation. Conclusion Unstimulated and antigen-specific levels of CRP, SAA, IP-10, MMP-2 and sCD40L hold promise as diagnostic candidates for TB disease in short-term stimulation assays. Larger studies are required to validate these findings but the data suggest that antigen-specific cytokine production and in particular mutimarker biosignatures might contribute to future diagnostic strategies.

Flight muscle catabolism during overnight fasting in a passerine bird, Eremophila alpestris.  

PubMed

Brood-rearing passerine birds often have sparse lipid reserves coupled with potentially high energy demands. This may necessitate increased fasting protein catabolism; however, the largest source of protein, flight muscle, must be maintained. This problem was examined in the horned lark (Eremophila alpestris), a 28-g passerine. Overnight fasting caused significant depletion of protein in flight muscle and liver, but not in other muscle groups. Proteolytic enzyme activity of the flight muscle doubled during fasting. Biochemical and ultrastructural studies revealed that protein was depleted disproportionately from the sarcoplasm of flight muscle cells. Fasting caused a reduction in the protein-specific glycolytic capacity of flight muscle tissue. Oxidative capacity of the flight muscle, as measured by both in vivo and in vitro assays, was not significantly affected. The disproportionate catabolism of flight muscle sarcoplasmic protein may be due to a greater susceptibility to proteolysis, and not necessarily because it represents a source of redundant storage protein.

Artificial Pancreas Using a Personalized Rule-Based Controller Achieves Overnight Normoglycemia in Patients with Type 1 Diabetes  

PubMed Central

Abstract Objective: This study assessed the efficacy of a closed-loop (CL) system consisting of a predictive rule-based algorithm (pRBA) on achieving nocturnal and postprandial normoglycemia in patients with type 1 diabetes mellitus (T1DM). The algorithm is personalized for each patient's data using two different strategies to control nocturnal and postprandial periods. Research Design and Methods: We performed a randomized crossover clinical study in which 10 T1DM patients treated with continuous subcutaneous insulin infusion (CSII) spent two nonconsecutive nights in the research facility: one with their usual CSII pattern (open-loop [OL]) and one controlled by the pRBA (CL). The CL period lasted from 10 p.m. to 10 a.m., including overnight control, and control of breakfast. Venous samples for blood glucose (BG) measurement were collected every 20?min. Results: Time spent in normoglycemia (BG, 3.9–8.0?mmol/L) during the nocturnal period (12 a.m.–8 a.m.), expressed as median (interquartile range), increased from 66.6% (8.3–75%) with OL to 95.8% (73–100%) using the CL algorithm (P<0.05). Median time in hypoglycemia (BG, <3.9?mmol/L) was reduced from 4.2% (0–21%) in the OL night to 0.0% (0.0–0.0%) in the CL night (P<0.05). Nine hypoglycemic events (<3.9?mmol/L) were recorded with OL compared with one using CL. The postprandial glycemic excursion was not lower when the CL system was used in comparison with conventional preprandial bolus: time in target (3.9–10.0?mmol/L) 58.3% (29.1–87.5%) versus 50.0% (50–100%). Conclusions: A highly precise personalized pRBA obtains nocturnal normoglycemia, without significant hypoglycemia, in T1DM patients. There appears to be no clear benefit of CL over prandial bolus on the postprandial glycemia. PMID:24152323

Electroencephalogram (EEG) duration needed to detect abnormalities in angelman syndrome: is 1 hour of overnight recording sufficient?  

PubMed

Approximately, 90% of patients with Angelman syndrome present with epileptic seizures. Obtaining an electroencephalogram (EEG) with sleep improves the chances of detecting ictal, interictal, and benign abnormal rhythms in Angelman syndrome. However, electroencephalograms, even when obtained during sleep, can be challenging in this population because of tactile sensitivities as well as anxiety related to a novel environment. We tested the hypothesis that 1 hour of sleep on an electroencephalogram would provide as much information as an entire night of electroencephalogram recording, yet more than a routine electroencephalogram conducted during the day. Overnight polysomnograms were collected in 14 children with Angelman syndrome seen at Vanderbilt University. All patients who obtained sleep within the first hour of the overnight electroencephalogram had interictal discharges recorded. Our results show that when sleep is obtained, a 1-hour electroencephalogram yields just as much information as recording an entire night. PMID:24820335

Comparison of 24-h and overnight samples of urinary 5-hydroxyindoleacetic acid in patients with intestinal neuroendocrine tumors  

PubMed Central

Neuroendocrine tumors (NETs) arising in the small intestine are known to produce vasoactive substances, including serotonin, that may result in the carcinoid syndrome (flushing, diarrhea, bronchoconstriction, and carcinoid heart disease). Measurement of the serotonin breakdown product 5-hydroxyindoleacetic acid (5-HIAA) in urine is important in diagnosing and monitoring of patients with intestinal NETs. Our aim was to compare 5-HIAA measurement in 24-h urine sampling with overnight (?8-h) sampling in patients with known NETs, or at follow-up of patients potentially cured for their NETs. Twenty-four-hour and overnight urine samples were collected from 34 patients and analyzed for urinary 5-HIAA (U5-HIAA) using HPLC. Comparison of the overnight sampling values with the 24-h values showed no difference, P=0.45, and there was a significant direct correlation between the two samples using linear regression (R=0.97, P<0.001). U5-HIAA sample collection during a nightly interval of ?8?h appears to have the same accuracy as the 24-h collection in this group of patients. PMID:23781318

The impact of on-site attending radiologist overnight coverage on radiology resident learning: a preliminary assessment.  

PubMed

The objective of this study is to assess the impact of on-site attending radiologist overnight coverage on resident education during transition to 24/7 attending coverage. The study was exempted from IRB review. An anonymous survey was sent to 9 second year radiology residents who completed their first night call rotation (NC) with an attending radiologist (group 1) and 18 residents who completed their first NC prior to overnight attending coverage (group 2). This addressed anxiety level prior to NC, work pace, autonomy and confidence, and attending feedback, with responses graded on a five-point scale. Statistical analysis was performed using Spearman's rho correlation coefficient. Diagnostic Radiology In-Training (DXIT(TM)) exam scores were collected prior to and following completion of the NC rotation, and results were compared. Case volume before and after the transition was recorded. p value <0.05 indicated statistical significance. Eight out of nine residents in group 1 and 16 out of/18 residents in group 2 completed the survey. Group 1 was more likely to report working at a comfortable pace (p?=?0.008) and receiving attending feedback (p?=?0.004) than group 2. A non-significant trend towards reduced anxiety prior to NC was present in group 1 (p?=?0.077). No difference in independence (p?=?0.918), autonomy (p?=?0.635), or confidence during (p?=?0.431) or after NC (p?=?1.00) was identified. DXIT(TM) scores were not significantly different between the two groups (p?=?0.396). While overall case volume dictated by residents increased, fewer plain radiographs were dictated. Overnight attending coverage provides a more comfortable pace of study interpretation and increased attending feedback without decreasing resident independence or DXIT(TM) scores. Plain radiograph interpretation may need to be further emphasized. PMID:24902658

Overnight Polysomnography versus Respiratory Polygraphy in the Diagnosis of Pediatric Obstructive Sleep Apnea  

PubMed Central

Background: Substantial discrepancies exist in the type of sleep studies performed to diagnose pediatric obstructive sleep apnea (OSA) in different countries. Respiratory polygraphic (RP) recordings are primarily performed in sleep laboratories in Europe, whereas polysomnography (PSG) constitutes the majority in the US and Australia. Home RP show consistent apnea-hypopnea index (AHI) underscoring, primarily because the total recording time is used as the denominator when calculating the AHI compared to total sleep time (TST). However, laboratory-based RP are less likely affected, since the presence of sleep technicians and video monitoring may enable more accurate TST estimates. We therefore examined differences in AHI in PSG and in-lab RP, and whether RP-based AHI may impact clinical decision making. Methods: Of all the children assessed for possible OSA who underwent PSG evaluation, 100 were identified and divided into 4 groups: (A) those with AHI < 1/h TST (n = 20), (B) 1 ? AHI < 5/h TST (n = 40), (C) 5 ? AHI < 10/h TST (n = 20), and (D) AHI ? 10/h TST (n = 20). Electroencephalography, electrooculography, and electromyography channels were deleted from the original unscored recordings to transform them into RP, and then rescored in random sequence. AHI-RP were compared to AHI-PSG, and therapeutic decisions based on AHI-RP and AHI-PSG were formulated and analyzed using clinical details derived from the patient's clinic letter. Results: Bland Altman analysis showed that in lab RP underestimated the AHI despite more accurate estimates of TST. This underestimation was due to missed hypopneas causing arousals without desaturation. Basing the therapeutic management decision on RP instead of PSG results changed the clinical management in 23% of all patients. The clinical management for patients in groups A and D was unaffected. However, 27.5% of patients in group B would have been given no treatment, as they would be diagnosed as having no OSA (AHI < 1/h TST) when they should have received a trial of anti-inflammatory therapy or been referred for ear, nose, and throat (ENT) review. Sixty percent of patients in group C would have received either a trial of medical treatment to treat mild OSA or no treatment, instead of referral to ENT services or commencement of continuous positive airway pressure. Conclusion: Apnea-hypopnea index (AHI) is underestimated in respiratory polygraphy (RP), and the disparity in AHI-RP and AHI-polysomnography can significantly affect clinical management decisions, particularly in children with mild and moderate obstructive sleep apnea (1 < AHI < 10/h total sleep time).

The relationship of plasma indicators of lipid metabolism and muscle damage to overnight temperature in winter-acclimatized small birds.  

PubMed

Plasma glycerol and triglyceride levels and creatine kinase (CK) activity may increase during long-distance flights in migratory birds, but plasma profiles of these metabolites have not previously been reported for small birds during thermoregulation in cold climates. We measured early morning levels of plasma glycerol, triglycerides and CK activity in four species of small birds overwintering in South Dakota, Junco hyemalis, Spizella arborea, Passer domesticus, and Carduelis tristis. We hypothesized that metabolite levels and CK activity might vary with overnight temperature (measured as the temperature just prior to dawn), with higher levels during colder temperatures which require elevated thermogenesis. Triglyceride and glycerol levels were not significantly related to temperature for any of the four species. Triglyceride levels were significantly positively associated with time since sunrise in J. hyemalis and C. tristis, and the time-temperature interaction was significant for S. arborea, suggesting rapid replacement of fat stores. Plasma glycerol levels were also significantly positively related to time since sunrise in J. hyemalis and C. tristis, but not in other species. Plasma CK activity showed a significant negative relationship to overnight temperature only for S. arborea. These results suggest that triglycerides do not comprise a major contribution to lipid supply during intense shivering in small birds. Similarly, intense shivering does not generally appear to result in muscle damage in small birds. PMID:17049895

Closing the loop overnight at home setting: psychosocial impact for adolescents with type 1 diabetes and their parents  

PubMed Central

Objective To explore the experiences of adolescents with type 1 diabetes mellitus (T1DM) and their parents taking part in an overnight closed loop study at home, using qualitative and quantitative research methods. Research design and methods Adolescents aged 12–18?years on insulin pump therapy were recruited to a pilot closed loop study in the home setting. Following training on the use of a study insulin pump and continuous glucose monitoring (CGM), participants were randomized to receive either real-time CGM combined with overnight closed loop or real-time CGM alone followed by the alternative treatment for an additional 21?days with a 2–3-week washout period in between study arms. Semistructured interviews were performed to explore participants’ perceptions of the impact of the closed loop technology. At study entry and again at the end of each 21-day crossover arm of the trial, participants completed the Diabetes Technology Questionnaire (DTQ) and Hypoglycemia Fear Survey (HFS; also completed by parents). Results 15 adolescents and 13 parents were interviewed. Key positive themes included reassurance/peace of mind, confidence, ‘time off’ from diabetes demands, safety, and improved diabetes control. Key negative themes included difficulties with calibration, alarms, and size of the devices. DTQ results reflected these findings. HFS scores were mixed. Conclusions Closed loop insulin delivery represents cutting-edge technology in the treatment of T1DM. Results indicate that the psychological and physical benefits of the closed loop system outweighed the practical challenges reported. Further research from longitudinal studies is required to determine the long-term psychosocial benefit of the closed loop technology. PMID:25452866

Hand-held multiple system gas chromatograph  

DOEpatents

A multiple parallel hand-held gas chromatograph (GC) system which includes several independent GCs. Each independent GC has its own injector, separation column, detector and oven and the GCs are mounted in a light weight hand-held assembly. Each GC operates independently and simultaneously. Because of different coatings in different separation columns, different retention times for the same gas will be measured. Thus, for a GC system with multiple parallel GCs, the system can measure, in a short period, different retention times and provide a cross-reference in the determination of the measured gas and to become a two-dimensional system for direct field use.

Significant deficiencies in the overnight use of a Standardised Early Warning Scoring system in a teaching hospital.  

PubMed

National Institute for Health and Clinical Excellence guidelines recommend the use of 'Track and Trigger' systems to identify early clinical deterioration. The Standardised Early Warning Score (SEWS) is used in the Royal Infirmary of Edinburgh. Previous work, suggested that the frequency and accuracy of SEWS documentation varied throughout the hospital. A prospective study was performed over a 14-night period looking at SEWS documentation in patients causing clinical concern requiring medical review, or triggering a SEWS of 4 (the 'trigger' score). SEWS charts were examined the following morning. In the ward arc, SEWS documentation was correct in only 21% of cases. The most frequent errors were one or more observations omitted (64%), SEWS total not calculated (55%) or incorrectly calculated (21%). Up to five errors per chart were noted. The observations most frequently omitted were respiratory rate, temperature and neurological status. In contrast, SEWS documentation was correct in 68% of patients in the combined assessment unit (CAU). This study demonstrates significant deficiencies in the overnight use of SEWS, particularly on the ward arc. This is particularly concerning as this study was limited only to patients already causing clinical concern, and highlights that basic observations are often incomplete, and the SEWS chart poorly understood and acted upon. SEWS recording and documentation was significantly better in CAU (P < 0.001, FET), where there is a dedicated, ongoing SEWS education programme for nursing and medical staff. We recommend this is rolled out across the hospital. Alternative methods of improving the use of SEWS are considered. PMID:21515526

High performance hand-held gas chromatograph  

SciTech Connect

The Microtechnology Center of Lawrence Livermore National Laboratory has developed a high performance hand-held, real time detection gas chromatograph (HHGC) by Micro-Electro-Mechanical-System (MEMS) technology. The total weight of this hand-held gas chromatograph is about five lbs., with a physical size of 8{close_quotes} x 5{close_quotes} x 3{close_quotes} including carrier gas and battery. It consumes about 12 watts of electrical power with a response time on the order of one to two minutes. This HHGC has an average effective theoretical plate of about 40k. Presently, its sensitivity is limited by its thermal sensitive detector at PPM. Like a conventional G.C., this HHGC consists mainly of three major components: (1) the sample injector, (2) the column, and (3) the detector with related electronics. The present HHGC injector is a modified version of the conventional injector. Its separation column is fabricated completely on silicon wafers by means of MEMS technology. This separation column has a circular cross section with a diameter of 100 pm. The detector developed for this hand-held GC is a thermal conductivity detector fabricated on a silicon nitride window by MEMS technology. A normal Wheatstone bridge is used. The signal is fed into a PC and displayed through LabView software.

Initial blood storage experiment  

NASA Technical Reports Server (NTRS)

The design of the Initial Blood Storage Experiment (IBSE) was based upon a carefully controlled comparison between identical sets of human blood cell suspensions - red cells, white cell, and platelets - one set of which was transported aboard the Columbia on a 6 day 11 hour mission, and the other held on the ground. Both sets were carried inside stainless steel dewars within specially fabricated flight hardware. Individual bags of cell suspensions were randomly assigned with respect to ground vs orbit status, dewar chamber, and specific location within the dewar. To foster optimal preservation, each cell type was held under specific optimal conditions of pH, ionic strength, solute concentration, gas tension, and temperature. An added variable in this initial experiment was provided by the use of three different polymer/plasticizer formulations for the sealed bags which held the blood cells. At termination of the experiment, aliquots of the suspensions, identified only by code, were distributed to be assayed. Assays were selected to constitute a broad survey of cellular properties and thereby maximize the chances of detection of gravitational effects. A total of 74 different outcome measurements were reported for statistical analysis. When the measurements were completed, the results were entered into the IBSE data base, at which time the data were matched with the original blood bag numbers to determine their status with respect to polymer/plasticizer type, orbit status (orbit or ground), and storage position within the experimental hardware. The data were studied by analysis of variance. Initially, type of bag and orbital status were main factors; later more detailed analyses were made on specific issues such as position in the hardware and specific plastic. If the analysis of variance indicated a statistical significance at the 5 percent level the corresponding p-value was reported.

The Use of an Automated, Portable Glucose Control System for Overnight Glucose Control in Adolescents and Young Adults With Type 1 Diabetes  

PubMed Central

OBJECTIVE A key milestone in progress towards providing an efficacious and safe closed-loop artificial pancreas system for outpatient use is the development of fully automated, portable devices with fault detection capabilities to ensure patient safety. The ability to remotely monitor the operation of the closed-loop system would facilitate future physician-supervised home studies. RESEARCH DESIGN AND METHODS This study was designed to investigate the efficacy and safety of a fully automated, portable, closed-loop system. The Medtronic Portable Glucose Control System (PGCS) consists of two subcutaneous glucose sensors, a control algorithm based on proportional-integral-derivative with insulin feedback operating from a BlackBerry Storm smartphone platform, Bluetooth radiofrequency translator, and an off-the-shelf Medtronic Paradigm Veo insulin pump. Participants with type 1 diabetes using insulin pump therapy underwent two consecutive nights of in-clinic, overnight, closed-loop control after a baseline open-loop assessment. RESULTS Eight participants attended for 16 overnight studies. The PGCS maintained mean overnight plasma glucose levels of 6.4 ± 1.7 mmol/L (115 ± 31 mg/dL). The proportion of time with venous plasma glucose <3.9, between 3.9 and 8 (70 and 144 mg/dL), and >8 mmol/L was 7, 78, and 15%, respectively. The proportion of time the sensor glucose values were maintained between 3.9 and 8 mmol/L was greater for closed-loop than open-loop (84.5 vs. 46.7%; P < 0.0001), and time spent <3.3 mmol/L was also reduced (0.9 vs. 3%; P < 0.0001). CONCLUSIONS These results suggest that the PGCS, an automated closed-loop device, is safe and effective in achieving overnight glucose control in patients with type 1 diabetes. PMID:22875230

Artificial blood  

PubMed Central

Artificial blood is a product made to act as a substitute for red blood cells. While true blood serves many different functions, artificial blood is designed for the sole purpose of transporting oxygen and carbon dioxide throughout the body. Depending on the type of artificial blood, it can be produced in different ways using synthetic production, chemical isolation, or recombinant biochemical technology. Development of the first blood substitutes dates back to the early 1600s, and the search for the ideal blood substitute continues. Various manufacturers have products in clinical trials; however, no truly safe and effective artificial blood product is currently marketed. It is anticipated that when an artificial blood product is available, it will have annual sales of over $7.6 billion in the United States alone. PMID:19742251

Effect of electrical stun/kill method, interval between killing and neck cutting and blood vessels cut on blood loss and meat quality in broilers.  

PubMed

1. Broiler chickens were killed using either an electrical waterbath (WB system) delivering 120 mA per bird (50 Hz, alternating current, AC) for 4 s or an alternative stun/kill method (ASK system); where head-only stunning for 1 s was immediately followed by head-to-body (vent) application for 1 s (150 mA, 50 Hz sine wave AC). Within each stun/kill system, the neck was cut ventrally or unilaterally 20, 60, or 180 s after killing. In addition, a control group of broilers was stunned with 100 mA per bird in a waterbath using 1500 Hz AC for 4 s and were bled by a ventral neck cut within 20 s. 2. Blood leaving the neck cut was collected for 90 s in a bin placed on an electronic balance and blood loss (g/kg body weight) calculated. 3. Individually identified, unplucked and uneviscerated carcases were held at ambient temperature until the end of the experimental day and then stored overnight in an air chiller (5 degrees C). The carcases were dissected and the incidence of broken furculum and coracoid bones, haemorrhaging in P. minor and P. major muscles, and discolouration of P. major muscles were determined. 4. When neck cutting was performed in broilers 20 s after the stun or kill, the ASK and WB systems, in comparison with high frequency stunning, produced on average about 10 g per kg less bleed out. Within the stun/kill systems, broilers killed by ASK had a greater bleed out than in the WB system. Neck cutting at 20 s or 60 s post-kill resulted in a greater bleed out than when performed after a delay of 180 s. Ventral or unilateral neck cutting resulted in a similar bleed out. 5. Stunning broilers with 1500 Hz AC resulted in lower incidences of broken bones, haemorrhaging in breast muscles and muscle discolouration post mortem than the stun/kill systems. These defects were significantly lower in the ASK than in the WB system. Delayed neck cutting increased the severity of discolouration occurring Post mortem in the breast muscles. 6. It is suggested that broilers killed by ASK can be neck cut with a delay of up to 180 s without compromising bleed out. The incidence of broken bones and haemorrhaging in breast muscles are significantly less with ASK than WB. 7. Owing to the commercial benefits and potential for improved welfare at slaughter, ASK would appear to be a better method than WB. PMID:11337968

ORNL devised "dynamic loading," which employed a spinning rotor to load, transfer, and analyze blood samples by centrifugal processing. A refined, commercial version of the system was produced by ABAXIS and is marketed as portable ABAXIS MiniLab MCA. Used in a doctor's office, the equipment can perform 80 to 100 chemical blood tests on a single drop of blood and report results in five minutes. Further development is anticipated.

The Chicago Historical Society (CHS) and Northwestern University have recently unveiled this fine online exhibit. The site is an interesting example of how contemporary scientific research methods (specifically DNA forensics) can be used to help solve the problem of authentication of historical museum objects. Conceived and created by the Textile Curator of the CHS, the site traces ongoing efforts made to authenticate blood stains on a cloak belonging to Mary Todd Lincoln and other Lincoln assassination relics held by the CHS. It offers a review of both these relics and their provenance and the scientific methods used, as well as QuickTime movies of the experts in action, and a QTVR tour of the textile conservation lab. In all, an interesting and surprisingly detailed look at the merger of history and forensic science.

?-Cell Lipotoxicity After an Overnight Intravenous Lipid Challenge and Free Fatty Acid Elevation in African American Versus American White Overweight/Obese Adolescents  

PubMed Central

Objective: Overweight/obese (OW/OB) African American (AA) adolescents have a more diabetogenic insulin secretion/sensitivity pattern compared with their American white (AW) peers. The present study investigated ?-cell lipotoxicity to test whether increased free fatty acid (FFA) levels result in greater ?-cell dysfunction in AA vs AW OW/OB adolescents. Research Design and Methods: Glucose-stimulated insulin secretion was modeled, from glucose and C-peptide concentrations during a 2-hour hyperglycemic (225 mg/dL) clamp in 22 AA and 24 AW OW/OB adolescents, on 2 occasions after a 12-hour overnight infusion of either normal saline or intralipid (IL) in a random sequence. ?-Cell function relative to insulin sensitivity, the disposition index (DI), was examined during normal saline and IL conditions. Substrate oxidation was evaluated with indirect calorimetry and body composition and abdominal adiposity with dual-energy X-ray absorptiometry and magnetic resonance imaging at L4-L5, respectively. Results: Age, sex, body mass index, total and sc adiposity were similar between racial groups, but visceral adiposity was significantly lower in AAs. During IL infusion, FFAs and fat oxidation increased and insulin sensitivity decreased similarly in AAs and AWs. ?-Cell glucose sensitivity of first- and second-phase insulin secretion did not change significantly during IL infusion in either group, but DI in each phase decreased significantly and similarly in AAs and AWs. Conclusions: Overweight/obese AA and AW adolescents respond to an overnight fat infusion with significant declines in insulin sensitivity, DI, and ?-cell function relative to insulin sensitivity, suggestive of ?-cell lipotoxicity. However, contrary to our hypothesis, there does not seem to be a race differential in ?-cell lipotoxicity. Longer durations of FFA elevation may unravel such race-related contrasts. PMID:23526462

Noninvasive measurement of murine hepatic acetyl-CoA ¹³C-enrichment following overnight feeding with ¹³C-enriched fructose and glucose.  

PubMed

The (13)C-isotopomer enrichment of hepatic cytosolic acetyl-CoA of overnight-fed mice whose drinking water was supplemented with [U-(13)C]fructose, and [1-(13)C]glucose and p-amino benzoic acid (PABA) was quantified by (13)C NMR analysis of urinary N-acetyl-PABA. Four mice were given normal chow plus drinking water supplemented with 5% [1-(13)C]glucose, 2.5% [U-(13)C]fructose, and 2.5% fructose (Solution 1) overnight. Four were given chow and water containing 17.5% [1-(13)C]glucose, 8.75% [U-(13)C]fructose and 8.75% fructose (Solution 2). PABA (0.25%) was present in both studies. Urinary N-acetyl-PABA was analyzed by (13)C NMR. In addition to [2-(13)C]- and [1,2-(13)C]acetyl isotopomers from catabolism of [U-(13)C]fructose and [1-(13)C]glucose to acetyl-CoA, [1-(13)C]acetyl was also found indicating pyruvate recycling activity. This precluded precise estimates of [1-(13)C]glucose contribution to acetyl-CoA while that of [U-(13)C]fructose was unaffected. The fructose contribution to acetyl-CoA from Solutions 1 and 2 was 4.0 ± 0.4% and 10.6 ± 0.6%, respectively, indicating that it contributed to a minor fraction of lipogenic acetyl-CoA under these conditions.

Biliary lipid output during three meals and an overnight fast. I. Relationship to bile acid pool size and cholesterol saturation of bile in gallstone and control subjects.  

PubMed Central

Using a duodenal perfusion technique, the biliary output of bile acids, phospholipid, and cholesterol was measured hourly during three meals and an overnight fast in seven Caucasians with radiolucent gallstones in a functioning gallbladder, and in seven health controls without gallstones, closely matched for age, sex, and weight. Before the perfusion, bile acid kinetics were defined by an isotope dilution procedure, and the biliary lipid composition of fasting gallbladder bile was determined. Total daily biliary lipid output was similar in gallstone and control subjects, and was unrelated to cholesterol saturation of fasting gallbladder bile and to bile acid pool size. There was an inverse relationship between the size and recycling frequency of the bile acid pool, so that secretion rate and hepatic return of bile acids remained constant, despite a wide range of pool sizes. The finding of a normal bile acid synthesis rate in subjects with a small pool size therefore indicated normal feedback regulation of bile acid synthesis. Hourly measurements of biliary lipid output showed a linear relationship between bile acid and cholesterol output, with a similar regression line for gallstone and control subjects, but a non-linear relationship between bile acid and phospholipid output. Consequently, samples from all subjects were consistently supersaturated with cholesterol at low bile acid outputs, especially during overnight fasting, but not at high bile acid outputs. These findings indicate that hepatic secretion of bile supersaturated with cholesterol is physiological in man at low bile acid outputs, that bile acid pool size is probably determined in part by its recycling frequency, and that cholesterol cholelithiasis in some Caucasians may be due to an underlying extrahepatic abnormality.

Effects of Blood Transportation on Human Peripheral Mononuclear Cell Yield, Phenotype and Function: Implications for Immune Cell Biobanking  

PubMed Central

Human biospecimen collection, processing and preservation are rapidly emerging subjects providing essential support to clinical as well as basic researchers. Unlike collection of other biospecimens (e.g. DNA and serum), biobanking of viable immune cells, such as peripheral blood mononuclear cells (PBMC) and/or isolated immune cell subsets is still in its infancy. While certain aspects of processing and freezing conditions have been studied in the past years, little is known about the effect of blood transportation on immune cell survival, phenotype and specific functions. However, especially for multicentric and cooperative projects it is vital to precisely know those effects. In this study we investigated the effect of blood shipping and pre-processing delay on immune cell phenotype and function both on cellular and subcellular levels. Peripheral blood was collected from healthy volunteers (n?=?9): at a distal location (shipped overnight) and in the central laboratory (processed immediately). PBMC were processed in the central laboratory and analyzed post-cryopreservation. We analyzed yield, major immune subset distribution, proliferative capacity of T cells, cytokine pattern and T-cell receptor signal transduction. Results show that overnight transportation of blood samples does not globally compromise T- cell subsets as they largely retain their phenotype and proliferative capacity. However, NK and B cell frequencies, the production of certain PBMC-derived cytokines and IL-6 mediated cytokine signaling pathway are altered due to transportation. Various control experiments have been carried out to compare issues related to shipping versus pre-processing delay on site. Our results suggest the implementation of appropriate controls when using multicenter logistics for blood transportation aiming at subsequent isolation of viable immune cells, e.g. in multicenter clinical trials or studies analyzing immune cells/subsets. One important conclusion might be that despite changes due to overnight shipment, highly standardized central processing (and analysis) could be superior to multicentric de-central processing with more difficult standardization.

Feasibility of overnight closed-loop therapy in young children with type 1 diabetes aged 3–6?years: comparison between diluted and standard insulin strength  

PubMed Central

Objective To assess feasibility of overnight closed-loop therapy in young children with type 1 diabetes and contrast closed loop using diluted versus standard insulin strength. Research design and methods Eleven children (male 6; age range 3.75–6.96?years; glycated hemoglobin 60 (14) mmol/mol; body mass index SD score 1.0 (0.8); diabetes duration 2.2 (1.0) years, mean (SD); total daily dose 12.9 (10.6, 16.5) IU/day, median (IQR)) were studied at a clinical research facility on two occasions. In random order, participants received closed loop with diluted insulin aspart (CL_Dil; 20?IU/mL) or closed loop with standard aspart (CL_Std; 100?IU/mL) from 17:00 until 8:00 the following morning. Children consumed an evening meal at 17:00 (44 (12) gCHO) and an optional bedtime snack (6 (7) gCHO) identical on both occasions. Meal insulin boluses were calculated by standard pump bolus calculators. Basal rates on insulin pump were adjusted every 15?min as directed by a model-predictive-control algorithm informed by a real-time glucose sensor values. Results Mean plasma glucose was 122 (24) mg/dL during CL_Dil vs 122 (23) mg/dL during CL_Std (p=0.993). The time spent in the target glucose range 70–145?mg/dL was 83 (70, 100)% vs 72 (54, 81)% (p=0.328). Time above 145?mg/dL was 13 (0, 27)% vs 19 (10, 45)% (p=0.477) and time spent below 70?mg/dL was 0.0 (0.0, 1.4)% vs 1.4 (0.0, 11.6)% (p=0.161). One asymptomatic hypoglycemia below 63?mg/dL occurred in one participant during CL_Dil versus six episodes in five participants during CL_Std (p=0.09). Glucose variability measured by CV of plasma glucose tended to be reduced during CL_Dil (20% (13, 31) vs 32% (24, 42), p=0.075). Conclusions In this feasibility study, closed-loop therapy maintained good overnight glucose control with tendency towards reduced hypoglycemia and reduced glucose variability using diluted insulin.

Young Blood  

NSDL National Science Digital Library

Old muscles heal faster when they're exposed to young blood. That's the conclusion of a recent experiment in mice, led by Stanford University neurologist Thomas Rando. His team found that blood from younger mice stimulated stem cells in the muscles and livers of older mice. Those are the cells that generate new tissue. It's not clear what part of the young blood makes the difference, but Dr. Rando suspects it's a combination of factors. If scientists can solve the mystery, they may be able to develop new ways to help injuries and broken bones heal more quickly. This Science Update looks at the research, which leads to these findings and offers links to other resources for further inquiry. There are also links to Science Netlinks Lesson plans for use at the 6-8 grade level.

The method that is used for the collection, storage and real-time analysis of blood and other bodily fluids has been licensed to DBCD, Inc. by NASA. The result of this patent licensing agreement has been the development of a commercial product that can provide serum or plasma from whole blood volumes of 20 microliters to 4 milliliters. The device has a fibrous filter with a pore size of less than about 3 microns, and is coated with a mixture of mannitol and plasma fraction protein. The coating causes the cellular fraction to be trapped by the small pores, leaving the cellular fraction intact on the fibrous filter while the acellular fraction passes through the filter for collection in unaltered form from the serum sample collection chamber. The method used by this product is useful to NASA for blood analysis on manned space missions.

The value of early SPECT/CT and hand-held ?-camera in radio-guided surgery: a case of a hard-to-locate parathyroid adenoma.  

PubMed

A patient with primary hyperparathyroidism underwent radio-guided surgery by means of a ?-probe and a hand-held ?-camera. Before surgery, a parathyroid double-phase planar scintigraphy and an early SPECT/CT with 99mTc-MIBI were performed and suggested an ectopic parathyroid adenoma with early washout. The hand-held ?-camera was very useful for the localization of a parathyroid adenoma, which could not be found with the probe probably due to its faint uptake and to a high blood pool activity because it was localized next to the great vessels. Besides, it demonstrated the complete extirpation of the parathyroid tissue. PMID:24999697

A set of notes was developed to aid the beginner in hand-held radiometry. The electromagnetic spectrum is reviewed, and pertinent terms are defined. View areas of multiband radiometers are developed to show the areas of coincidence of adjacent bands. The amounts of plant cover seen by radiometers having different fields of view are described. Vegetation indices are derived and discussed. Response functions of several radiometers are shown and applied to spectrometer data taken over 12 wheat plots, to provide a comparison of instruments and bands within and among instruments. The calculation of solar time is reviewed and applied to the calculation of the local time of LANDSAT satellite overpasses for any particular location in the Northern Hemisphere. The use and misuse of hand-held infrared thermometers are discussed, and a procedure for photographic determination of plant cover is described. Some suggestions are offered concerning procedures to be followed when collecting hand-held spectral and thermal data. A list of references pertinent to hand-held radiometry is included.

Overnight improvements in two REM sleep-sensitive tasks are associated with both REM and NREM sleep changes, sleep spindle features, and awakenings for dream recall.  

PubMed

Memory consolidation is associated with sleep physiology but the contribution of specific sleep stages remains controversial. To clarify the contribution of REM sleep, participants were administered two REM sleep-sensitive tasks to determine if associated changes occurred only in REM sleep. Twenty-two participants (7 men) were administered the Corsi Block Tapping and Tower of Hanoi tasks prior to and again after a night of sleep. Task improvers and non-improvers were compared for sleep structure, sleep spindles, and dream recall. Control participants (N=15) completed the tasks twice during the day without intervening sleep. Overnight Corsi Block improvement was associated with more REM sleep whereas Tower of Hanoi improvement was associated with more N2 sleep. Corsi Block improvement correlated positively with %REM sleep and Tower of Hanoi improvement with %N2 sleep. Post-hoc analyses suggest Tower of Hanoi effects-but not Corsi Block effects-are due to trait differences. Sleep spindle density was associated with Tower of Hanoi improvement whereas spindle amplitude correlated with Corsi Block improvement. Number of REM awakenings for dream reporting (but not dream recall per se) was associated with Corsi Block, but not Tower of Hanoi, improvement but was confounded with REM sleep time. This non-replication of one of 2 REM-sensitive task effects challenges both 'dual-process' and 'sequential' or 'sleep organization' models of sleep-dependent learning and points rather to capacity limitations on REM sleep. Experimental awakenings for sampling dream mentation may not perturb sleep-dependent learning effects; they may even enhance them. PMID:25291630

Engineering issues for hand-held sensing devices, with examples  

NASA Astrophysics Data System (ADS)

It is now U.S. defense policy that there will be no new platform starts. The emphasis for platforms will be on O&M cost reduction, life-extension improvements, and force-multiplier- device upgrades. There is also an increasing emphasis on hand-held force-multiplier devices for individuals, which is the focus of this paper. Engineering issues include operations analysis, weight, cube, cost, prime power, ease of use, data storage, reliability, fault tolerance, data communications and human factors. Two examples of hand-held devices are given. Applications include USMC, Army, SOCOM, DEA, FBI, SS, Border Patrol and others. Barriers to adoption of such technology are also discussed.

Formation and Maturation of the Calyx of Held  

PubMed Central

Sound localization requires precise and specialized neural circuitry. A prominent and well-studied specialization is found in the mammalian auditory brainstem. Globular bushy cells of the ventral cochlear nucleus (VCN) project contralaterally to neurons of the medial nucleus of the trapezoid body (MNTB), where their large axons terminate on cell bodies of MNTB principal neurons, forming the calyces of Held. The VCN-MNTB pathway is necessary for the accurate computation of interaural intensity and time differences; MNTB neurons provide inhibitory input to the lateral superior olive, which compares levels of excitation from the ipsilateral ear to levels of tonotopically matched inhibition from the contralateral ear, and to the medial superior olive, where precise inhibition from MNTB neurons tunes the delays of binaural excitation. Here we review the morphological and physiological aspects of the development of the VCN-MNTB pathway and its calyceal termination, along with potential mechanisms that give rise to its precision. During embryonic development, VCN axons grow towards the midline, cross the midline into the region of the presumptive MNTB and then form collateral branches that will terminate in calyces of Held. In rodents, immature calyces of Held appear in MNTB during the first few days of postnatal life. These calyces mature morphologically and physiologically over the next three postnatal weeks, enabling fast, high fidelity transmission in the VCN-MNTB pathway. PMID:21093567

Hand-held terminal antennas for personal satellite communications  

NASA Technical Reports Server (NTRS)

This paper deals with two hand-held antenna types operating with geostationary and medium earth orbit (GEO and MEO) satellite systems. They could be applied to the low earth orbit (LEO) and highly elliptical orbit (HEO) systems respectively doing the appropriate frequency scale designs. The first one is a lambda/2 (1/2 turn) quadrifilar helix (quasi-hemispherical coverage), and the second one is a self-diplexed antenna made of a circular patch and a short-circuited ring patch in stacked configuration (zenithal coverage).

Visual SLAM for Hand-Held Monocular Endoscope.  

PubMed

Simultaneous Localisation And Mapping (SLAM) methods provide real-time estimation of 3D models from the sole input of a hand-held camera, routinely in mobile robotics scenarios. Medical endoscopic sequences mimic a robotic scenario in which a hand-held camera (monocular endoscope) moves along an unknown trajectory while observing an unknown cavity. However, the feasibility and accuracy of SLAM methods have not been extensively validated with human in-vivo image sequences. In this work, we propose a monocular visual SLAM algorithm tailored to deal with medical image sequences in order to provide an up-to-scale 3D map of the observed cavity and the endoscope trajectory at frame rate. The algorithm is validated over synthetic data and human in-vivo sequences corresponding to fifteen laparoscopic hernioplasties where accurate ground-truth distances are available. It can be concluded that the proposed procedure is: 1) non invasive, because only a standard monocular endoscope and a surgical tool are used; 2) convenient, because only a handcontrolled exploratory motion is needed; 3) fast, because the algorithm provides the 3D map and the trajectory in real time; 4) accurate, because it has been validated with respect to groundtruth; and 5) robust to inter-patient variability, because it has performed successfully over the validation sequences.

A Hand-Held Beta Imaging Probe for FDG  

PubMed Central

Objectives Advances in radiopharmaceuticals and clinical understanding have escalated the use of intraoperative gamma probes in surgery. However, most probes on the market are non-imaging gamma probes that suffer from the lack of ancillary information of the surveyed tissue area. We have developed a novel, hand-held digital Imaging Beta Probe™ (IBP™) to be used in surgery in conjunction with beta-emitting radiopharmaceuticals such as 18FDG, 131I and 32P for real-time imaging of a surveyed area with higher spatial resolution and sensitivity and greater convenience than existing instruments. Methods We describe the design and validation of a hand-held beta probe intended to be used as a visual mapping device to locate and confirm excision of 18FDG-avid primary tumors and metastases in an animal model. Results We have demonstrated a device which can generate beta images from 18FDG avid lesions in an animal model. Conclusions It is feasible to image beta irradiation in animal models of cancer given 18FDG. This technology may be applied to clinical mapping of tumors and/or their metastases in the operating room. Visual image depiction of malignancy may aid the surgeon in localization and excision of lesions of interest. PMID:23229110

Bone age maturity assessment using hand-held device  

NASA Astrophysics Data System (ADS)

Purpose: Assessment of bone maturity is traditionally performed through visual comparison of hand and wrist radiograph with existing reference images in textbooks. Our goal was to develop a digital index based on idealized hand Xray images that can be incorporated in a hand held computer and used for visual assessment of bone age for patients. Material and methods: Due to the large variability in bone maturation in normals, we generated a set of "ideal" images obtained by computer combinations of images from our normal reference data sets. Software for hand-held PDA devices was developed for easy navigation through the set of images and visual selection of matching images. A formula based on our statistical analysis provides the standard deviation from normal based on the chronological age of the patient. The accuracy of the program was compared to traditional interpretation by two radiologists in a double blind reading of 200 normal Caucasian children (100 boys, 100 girls). Results: Strong correlations were present between chronological age and bone age (r > 0.9) with no statistical difference between the digital and traditional assessment methods. Determinations of carpal bone maturity in adolescents was slightly more accurate using the digital system. The users did praise the convenience and effectiveness of the digital Palm Index in clinical practice. Conclusion: An idealized digital Palm Bone Age Index provides a convenient and effective alternative to conventional atlases for the assessment of skeletal maturity.

Ultratrace detector for hand-held gas chromatography  

DOEpatents

An ultratrace detector system for hand-held gas chromatography having high sensitivity, for example, to emissions generated during production of weapons, biological compounds, drugs, etc. The detector system is insensitive to water, air, helium, argon, oxygen, and C0.sub.2. The detector system is basically composed of a hand-held capillary gas chromatography (GC), an insulated heated redox-chamber, a detection chamber, and a vapor trap. For example, the detector system may use gas phase redox reactions and spectral absorption of mercury vapor. The gas chromatograph initially separates compounds that percolate through a bed of heated mercuric oxide (HgO) in a silica--or other metal--aerogel material which acts as an insulator. Compounds easily oxidized by HgO liberate atomic mercury that subsequently pass through a detection chamber which includes a detector cell, such as quartz, that is illuminated with a 254 nm ultra-violet (UV) mercury discharge lamp which generates the exact mercury absorption bands that are used to detect the liberated mercury atoms. Atomic mercury strongly absorbs 254 nm energy is therefore a specific signal for reducing compounds eluting from the capillary GC, whereafter the atomic mercury is trapped for example, in a silicon-aerogel trap.

Rapid DNA Extraction from Dried Blood Spots on Filter Paper: Potential Applications in Biobanking  

PubMed Central

Objectives Dried blood spot (DBS) technology is a microsampling alternative to traditional plasma or serum sampling for pharmaco- or toxicokinetic evaluation. DBS technology has been applied to diagnostic screening in drug discovery, nonclinical, and clinical settings. We have developed an improved elution protocol involving boiling of blood spots dried on Whatman filter paper. Methods The purpose of this study was to compare the quality, purity, and quantity of DNA isolated from frozen blood samples and DBSs. We optimized a method for extraction and estimation of DNA from blood spots dried on filter paper (3-mm FTA card). A single DBS containing 40 ?L blood was used. Results DNA was efficiently extracted in phosphate-buffered saline (PBS) or Tris-EDTA (TE) buffer by incubation at 37°C overnight. DNA was stable in DBSs that were stored at room temperature or frozen. The housekeeping genes GAPDH and beta-actin were used as positive standards for polymerase chain reaction (PCR) validation of general diagnostic screening. Conclusion Our simple and convenient DBS storage and extraction methods are suitable for diagnostic screening by using very small volumes of blood collected on filter paper, and can be used in biobanks for blood sample storage.

Effect of Blood’s Velocity on Blood Resistivity  

E-print Network

Abstract — Blood resistivity is an important quantity whose value influences the results of various methods used in the study of heart and circulation. In this paper, the relationship between blood resistivity and velocity of blood flow was evaluated and analyzed based upon a probe using six-ring electrodes and a circulatory model. The experimental results indicated that the change in blood resistivity was only 61.1 % when the velocity of blood flow changed from 2.83 to 40 cm/s and it rose to 23 % when the velocity was lower than 2.83 cm/s. Index Terms—Blood flow, blood vessels, electrodes, resistivity measurement, velocity. Fig. 1. The red cell in cross section and its nominal dimension. I.

Pulp blood flow assessment in human teeth by laser Doppler flowmetry  

NASA Astrophysics Data System (ADS)

A laser Doppler instrument has been designed for blood flow measurements in the human pulp. By using infrared laser light from a laser diode the penetration into the tooth is considerably improved in comparison with earlier He-Ne measurements. A hand-held, pen-shaped probe facilitates the clinical use of the instrument. Restricted blood flow conditions in trauma patients, as well as the heart-rate synchronous pulsating nature of pulp blood in normal subjects, have been investigated.

Blood Donation by Elderly Repeat Blood Donors  

PubMed Central

Summary Background Upper age limits for blood donors are intended to protect elderly blood donors from donor reactions. However, due to a lack of data about adverse reactions in elderly blood donors, upper age limits are arbitrary and vary considerably between different countries. Methods Here we present data from 171,231 voluntary repeat whole blood donors beyond the age of 68 years. Results Blood donations from repeat blood donors beyond the age of 68 years increased from 2,114 in 2005 to 38,432 in 2012 (from 0,2% to 4.2% of all whole blood donations). Adverse donor reactions in repeat donors decreased with age and were lower than in the whole group (0.26%), even in donors older than 71 years (0.16%). However, from the age of 68 years, the time to complete recovery after donor reactions increased. Donor deferrals were highest in young blood donors (21.4%), but increased again in elderly blood donors beyond 71 years (12.6%). Conclusion Blood donation by regular repeat blood donors older than 71 years may be safely continued. However, due to a lack of data for donors older than 75 years, blood donation in these donors should be handled with great caution. PMID:25254019

Center of percussion of hand-held implements  

NASA Astrophysics Data System (ADS)

The center of percussion is commonly regarded as a sweet spot when referring to a baseball bat or a tennis racquet because it is assumed that there will be no sudden motion of the handle with respect to the hand if the corresponding axis of rotation passes through the hand. A problem with this interpretation is that the hand extends over a finite length of the handle and exerts an opposing reaction force on the handle. The hand also changes the total mass and moment of inertia of the system, while the arm restricts free motion of the hand. Experimental results are presented showing that the axis of rotation passes through the hand or the wrist for all the usual impact points on a hand-held implement. As a result, the impact point that feels best is usually the node of the fundamental vibration mode, not the center of percussion.

Oscillation frequencies of droplets held pendant on a nozzle  

SciTech Connect

Small-amplitude oscillations of liquid droplets held pendant on a nozzle and surrounded by either air or another liquid were investigated experimentally. The oscillations were induced by mechanical means, and the natural frequencies of oscillation were visually determined. Results are compared to existing related theories of Miller and Scriven and of Strani and Sabetta. As may be expected, the presence of the solid support causes measured oscillation frequencies for the lowest oscillation mode to deviate greatly from the Miller and Scriven low viscosity approximation (n = 2) for free spherical crops. Experiments are in qualitative agreement with the first (n = 1) mode predicted by Strani and Sabetta, with the best correspondence occurring under circumstances where the ratio of nozzle to drop radii is small. The difference between the experimental results and the theory of Strani and Sabetta can be attributed to the restrictive boundary conditions of their analytic model. Thus, better theoretical characterization of pendant droplet oscillations will require numerical computations.

Money for Blood and Markets for Blood.  

PubMed

Ontario's Bill 178 proposing a Voluntary Blood Donations Act declares the offer or acceptance of payment for the donation of blood a legal offence and makes it subject to penalty. The bill reinvigorates a fundamental debate about the ethical problems associated with the payment of money for blood. Scarcity of blood donors is a recurring problem in most health systems, and monetary remuneration of the willingness to donate blood is regularly discussed-and sometimes practiced-as a means to overcome scarcity in blood. However, making blood an object of economic exchange has long aroused ethical concerns that often refer to the specific meaning of blood. From the perspective of a modern understanding of money as a metric of economic value, the exchange of money for blood-shed or given-is seen as ethically troubling, because it appears to imply a commensurability of the value of human life and economic wealth. In this paper, we begin with a general taxonomy of the types of arguments that speak in favour or against compensating donors for giving blood. We then describe the context in which the discussion about payment for blood arises, and of the specific aims and concerns that are brought forward in this context. This is used to reconstruct the normative background that supports the rejection of payment for blood as it is envisaged in Bill 178 and the aims of the proposal. We then argue that while a payment indeed changes the nature of a blood donation in an ethically considerable way, we do not believe that decisive arguments against the monetary remuneration of blood donations can be substantiated, at least not independently of assuming specific societal circumstances. Thus it may be possible to establish a stable and safe blood supply through just gratification while at the same time taking strong provisions against social disconnection, injustice, exploitation or heteronomy.

Cordless hand-held optical 3D sensor  

NASA Astrophysics Data System (ADS)

A new mobile optical 3D measurement system using phase correlation based fringe projection technique will be presented. The sensor consist of a digital projection unit and two cameras in a stereo arrangement, whereby both are battery powered. The data transfer to a base station will be done via WLAN. This gives the possibility to use the system in complicate, remote measurement situations, which are typical in archaeology and architecture. In the measurement procedure the sensor will be hand-held by the user, illuminating the object with a sequence of less than 10 fringe patterns, within a time below 200 ms. This short sequence duration was achieved by a new approach, which combines the epipolar constraint with robust phase correlation utilizing a pre-calibrated sensor head, containing two cameras and a digital fringe projector. Furthermore, the system can be utilized to acquire the all around shape of objects by using the phasogrammetric approach with virtual land marks introduced by the authors 1, 2. This way no matching procedures or markers are necessary for the registration of multiple views, which makes the system very flexible in accomplishing different measurement tasks. The realized measurement field is approx. 100 mm up to 400 mm in diameter. The mobile character makes the measurement system useful for a wide range of applications in arts, architecture, archaeology and criminology, which will be shown in the paper.

Automatic feeder for small fish held in tanks  

USGS Publications Warehouse

The Northville (Michigan) Biological Station has been a center for study of the developmental morphology of coregonid fishes. This work requires the production of numerous individual series of lake herring, lake whitefish, and several species of chubs from parent fish of positively known identity. The offspring of individual pairs or groups of fish must be held in individual tanks from the time they hatch until they reach maturity. One of the important problems in this project has been the poor growth of most fish. Though some have grown well, their growth has been less than that of the same species in nature, and a few fish from each hatch have grown very slowly. Irregularity of feeding may contribute to the slow growth of laboratory fish. The hatchery caretaker feeds them several times during his 8-hour workday, but they must go without food during the remaining 16 hours. The high metabolic rate of small fish, however, appears to make them strongly inclined toward almost continual feeding. Belief that greater, more regular food consumption would result from a mechanical feeder providing a continuous supply of food over a longer period of the day led to development of the equipment described in this paper.

Stereo vision based hand-held laser scanning system design  

NASA Astrophysics Data System (ADS)

Although 3D scanning system is used more and more broadly in many fields, such computer animate, computer aided design, digital museums, and so on, a convenient scanning device is expansive for most people to afford. In another hand, imaging devices are becoming cheaper, a stereo vision system with two video cameras cost little. In this paper, a hand held laser scanning system is design based on stereo vision principle. The two video cameras are fixed tighter, and are all calibrated in advance. The scanned object attached with some coded markers is in front of the stereo system, and can be changed its position and direction freely upon the need of scanning. When scanning, the operator swept a line laser source, and projected it on the object. At the same time, the stereo vision system captured the projected lines, and reconstructed their 3D shapes. The code markers are used to translate the coordinate system between scanned points under different view. Two methods are used to get more accurate results. One is to use NURBS curves to interpolate the sections of the laser lines to obtain accurate central points, and a thin plate spline is used to approximate the central points, and so, an exact laser central line is got, which guards an accurate correspondence between tow cameras. Another way is to incorporate the constraint of laser swept plane on the reconstructed 3D curves by a PCA (Principle Component Analysis) algorithm, and more accurate results are obtained. Some examples are given to verify the system.

Blood lead levels and chronic blood loss  

SciTech Connect

Over 90% of lead in blood is bound to the erythrocytes. This high affinity of lead for red cells may mean that chronic blood loss is a significant means for excretion of lead. This study sought correlations between blood lead levels and clinical conditions involving chronic blood loss. During May, June and July, 146 patients with normal hematocrits and red cell indices were identified from the hospital and clinic populations. For each patient, age, race, sex and medical history were noted, and a whole blood sample was analyzed by flameless atomic absorption spectrophotometry. Age-and race-matched pairs showed a significant correlation of chronic blood loss with lead levels. Patients with the longest history of blood loss (menstruating women) had the lowest level (mean 6.13 ..mu..g/dl, range 3.6-10.3 ..mu..g/dl). Post-menopausal women had levels (7.29 ..mu..g/dl, 1.2-14 ..mu..g/dl) comparable to men with peptic ulcer disease, or colon carcinoma (7.31 ..mu..g/dl, 5.3-8.6 ..mu..g/dl). The highest levels were among men who had no history of bleeding problems (12.39 ..mu..g/dl, 2.08-39.35 ..mu..g/dl). Chronic blood loss may be a major factor responsible for sexual differences in blood lead levels. Since tissue deposition of environmental pollutants is implicated in diseases, menstruation may represent a survival advantage for women.

Hooking mortality and physiological responses of striped bass angled in freshwater and held in live-release tubes  

USGS Publications Warehouse

Mortality and physiological responses of adult striped bass Morone saxatilis angled from Lake Murray, South Carolina, and held in live-release tubes were evaluated during the spring and summer of 2003. To estimate mortality, we attached external ultrasonic transmitters to 59 striped bass (mean total length [TL] = 585 mm). Striped bass were caught with angling gear, tagged, and immediately released or held in live-release tubes for 2, 4, or 6 h prior to release. No mortality of striped bass was observed during spring. Overall mortality during summer was 83%. Mortality of summer-caught striped bass was not related to tube residence time, fish TL, depth of capture, or surface water temperature. To characterize physiological stress, we measured the plasma cortisol, glucose, lactate, and osmolality levels of 62 additional striped bass (mean TL = 563 mm) that were angled and immediately released or angled and held in live-release tubes. Plasma cortisol, glucose, lactate, and osmolality were positively related to tube residence time. When the hematological characteristics were considered only in relation to tube residence time, responses indicative of physiological stress continued for about 150 min, after which blood chemistry began to return to normal. Live-release tubes appear to be useful for keeping striped bass alive when they are angled from cool water, but they are not effective for striped bass angled from warm water. The high summer mortality of striped bass suggests a need for restrictive fishing regulations during the summer for the Lake Murray striped bass fishery. ??

The ecological context of soundscapes for children's blood pressure.  

PubMed

Although the majority of studies on community noise levels and children's physiological stress responses are positive, effect sizes vary considerably, and some studies do not confirm these effects. Employing a contextual perspective congruent with soundscapes, a carefully constructed sample of children (N?=?115, M?=?10.1?yr) living in households in relatively high (>60 dBA) or low (<50 dBA) noise areas created by proximity to major traffic arterials in Austria was reanalyzed. Several personal and environmental factors known to affect resting cardiovascular parameters measured under well-controlled, clinical conditions were incorporated into the analyses. Children with premature births and elevated chronic stress (i.e., overnight cortisol) were more susceptible to adverse blood pressure responses to road traffic noise. Residence in a multi-dwelling unit as well as standardized assessments of perceived quietness of the area did not modify the traffic noise impacts but each had its own, independent effect on resting blood pressure. A primary air pollutant associated with traffic volume (NO2) had no influence on any of these results. The scope of environmental noise assessment and management would benefit from incorporation of a more contextualized approach as suggested by the soundscape perspective. PMID:23862883

Characterization of HelD, an interacting partner of RNA polymerase from Bacillus subtilis  

PubMed Central

Bacterial RNA polymerase (RNAP) is an essential multisubunit protein complex required for gene expression. Here, we characterize YvgS (HelD) from Bacillus subtilis, a novel binding partner of RNAP. We show that HelD interacts with RNAP-core between the secondary channel of RNAP and the alpha subunits. Importantly, we demonstrate that HelD stimulates transcription in an ATP-dependent manner by enhancing transcriptional cycling and elongation. We demonstrate that the stimulatory effect of HelD can be amplified by a small subunit of RNAP, delta. In vivo, HelD is not essential but it is required for timely adaptations of the cell to changing environment. In summary, this study establishes HelD as a valid component of the bacterial transcription machinery. PMID:24520113

Court upholds $405,000 award against blood banking industry.  

PubMed

The New Jersey Superior Court has ruled that the American Association of Blood Banks (AABB), the nation's largest blood bank trade group, was negligent during the early 1980s when it recommended that blood banks not screen and test donors to reduce the chance of HIV contamination of the nation's blood supply. [Name removed], who received HIV-contaminated blood in 1984 as a result of a transfusion at St. Joseph's Hospital in Paterson, sued and reached out-of-court settlements with his doctors and the Bergen Community Blood Center, which provided the blood. Only the AABB suit proceeded to trial, with the jury finding that one-third of the damages were attributable to the AABB's actions. In 1983, the Centers for Disease Control and Prevention (CDC) suggested that blood banks might reduce the risk of AIDS entering the blood supply by using the surrogate hepatitis B test. The AABB, the American Red Cross, and the Council of Community Blood Centers recommended against testing, saying that evidence of transmission by blood was inconclusive and unproven. In March 1985, the AABB adopted the ELISA test. This is the first time the AABB has been held responsible; the AABB said it may appeal the decision. The court disagreed with AABB's claim that it was immune from liability because it was a charity, saying it also performs a critical governance function in respect of the operation of blood banks. The decision puts considerable liability for the U.S. cases of HIV contracted through tainted blood transfusions on the AABB. PMID:11362633

The relationship between blood lead and blood pressure in the NHANES II survey.  

PubMed Central

A large body of experimental data has shown that lead raises blood pressure and increases responsiveness to alpha-adrenergic agonists in rats and pigeons. These studies suggest the need to look for a similar relationship in humans. This paper examines the robustness of the previously reported association between blood lead and blood pressure in adult males. The association remains strong and is essentially unchanged in tests that include nutritional factors and demographic factors, alone or together, or in tests that include insignificant terms. The relationship was not confounded by age; it held for all adult men in the 20-45 age group, the 40-59 age group, and the 46-74 age group. Interaction terms for 25 30-year age groups (20-49, 21-50,. . . , 45-74) were all insignificant, indicating no difference in the relationship by age. The relationship is also robust to the inclusion of a time trend to account possible omitted time-varying factors, and it held in a model that controlled for possible site effects. Given the strong experimental evidence, the relationship is likely causal. PMID:3203634

Hand-Held Units for Short-Range Wireless Biotelemetry  

NASA Technical Reports Server (NTRS)

Special-purpose hand-held radiotransceiver units have been proposed as means of short-range radio powering and interrogation of surgically implanted microelectromechanical sensors and actuators. These units are based partly on the same principles as those of the units described in "Printed Multi- Turn Loop Antennas for RF Biotelemetry" (LEW-17879-1), NASA Tech Briefs, Vol. 31, No. 6 (June 2007), page 48. Like the previously reported units, these units would make it unnecessary to have wire connections between the implanted devices and the external equipment used to activate and interrogate them. Like a unit of the previously reported type, a unit of the type now proposed would include a printed-circuit antenna on a dielectric substrate. The antenna circuitry would include integrated surface-mount inductors for impedance tuning. Circuits for processing the signals transmitted and received by the antenna would be included on the substrate. During operation, the unit would be positioned near (but not in electrical contact with) a human subject, in proximity to a microelectromechanical sensor or actuator that has been surgically implanted in the subject. It has been demonstrated that significant electromagnetic coupling with an implanted device could be established at a distance of as much as 4 in. (.10 cm). During operation in the interrogation mode, the antenna of the unit would receive a radio telemetry signal transmitted by the surgically implanted device. The antenna substrate would have dimensions of approximately 3.25 by 3.75 inches (approximately 8.3 by 9.5 cm). The substrate would have a thickness of the order of 30 mils (of the order of a somewhat less than a millimeter). The substrate would be made of low-radiofrequency- loss dielectric material that could be, for example, fused quartz, alumina, or any of a number of commercially available radio-frequency dielectric composite materials. The antenna conductors would typically be made of copper or a combination of chromium and gold. The choice of metal and the thickness of the metal layer(s) would depend on the choice of substrate material. For example, on a quartz or alumina substrate, one would typically use a layer of chromium 150 A thick and a layer of gold 2 m thick. The proposed units and the implanted devices that they would interrogate or activate would be inherently safe to use. They would operate at low radiated-power levels for short interrogation times (typically, milliseconds). Hence, there would be little local heating of tissues surrounding the implanted devices and little absorption of radio energy by such sensitive body parts as the eyes and the brain. Because the implanted devices would not depend on battery power and would be activated only during short interrogation intervals and would otherwise be in the goff h state most of the time, the useful lifetimes of the implanted devices would be greater than those of comparable battery-powered implanted devices. The compactness of the hand-held transceiver units would facilitate transport and storage and would facilitate self-diagnosis by patients able to handle the units while away from medical facilities.

Electronic imaging system incorporating a hand-held fundus camera for canine ophthalmology.  

PubMed

An electronic imaging system incorporating a hand-held fundus camera was used to collect images of the canine ocular fundus. The electronic imaging system comprised a hand-held fundus camera, an IBM personal computer (PC 350), Microsoft Windows NT 4.0, Adobe Photoshop, and a color printer (Tektronix Phaser 550) and was used to store, edit, and print the images captured by the fundus camera. Hand-held fundus cameras are essential for use in canine ophthalmology. The Nidek NM-100 hand-held fundus camera digitalizes images, enabling their direct transfer into reports and their storage on writeable CDs. PMID:11703058

Direction-sensitive hand-held gamma-ray spectrometer  

NASA Astrophysics Data System (ADS)

A novel, light-weight, hand-held gamma-ray detector with directional sensitivity is being designed. The detector uses a set of multiple rings around two cylindrical surfaces, which provides precise location of two interaction points on two concentric cylindrical planes, wherefrom the source location can be traced back by back projection and/or Compton imaging technique. The detectors are 2.0 × 2.0 mm europium-doped strontium iodide (SrI2:Eu2+) crystals, whose light output has been measured to exceed 120,000 photons/MeV, making it one of the brightest scintillators in existence. The crystal's energy resolution, less than 3% at 662 keV, is also excellent, and the response is highly linear over a wide range of gamma-ray energies. The emission of SrI2:Eu2+ is well matched to both photo-multiplier tubes and blue-enhanced silicon photodiodes. The solid-state photomultipliers used in this design (each 2.0 × 2.0 mm) are arrays of active pixel sensors (avalanche photodiodes driven beyond their breakdown voltage in reverse bias); each pixel acts as a binary photon detector, and their summed output is an analog representation of the total photon energy, while the individual pixel accurately defines the point of interaction. A simple back-projection algorithm involving cone-surface mapping is being modeled. The back projection for an event cone is a conical surface defining the possible location of the source. The cone axis is the straight line passing through the first and second interaction points.

Perioperative blood management  

PubMed Central

Perioperative anaemia and allogenic blood transfusion (ABT) are known to increase the risk of adverse clinical outcomes. The quality, cost and availability of blood components are also major limitations with regard to ABT. Perioperative patient blood management (PBM) strategies should be aimed at minimizing and improving utilization of blood components. The goals of PBM are adequate preoperative evaluation and optimization of haemoglobin and bleeding parameters, techniques to minimize blood loss, blood conservation technologies and use of transfusion guidelines with targeted therapy. Attention to these details can help in cost reduction and improved patient outcome.

Home medical Blood pressure monitors Blood  

E-print Network

A blood pressure monitor, or sphygmomanometer, uses an inflatable air-bladder cuff and a listening device or pressure sensor to measure blood pressure in an artery. This monitoring can be performed by using either of two methods: a manually inflated cuff with a stethoscope for listening to arterial wall sounds (the auscultatory method), or a blood pressure monitor that contains a pressure sensor for sensing arterial wall vibrations (the oscillometric method). Automatic monitor types The two main types of automatic blood pressure monitors are upperarm and wrist models. The upper-arm model has a cuff that is placed on the upper arm; the cuff is connected by a tube to the monitor that rests on a surface near the arm. The wrist model is smaller and the entire unit wraps around the wrist—this is a much more space-critical design. Some upper-arm models require manual inflation of the cuff, but most upper-arm and all wrist models have fully automatic inflation. Measurement techniques An automatic blood pressure monitor inflates a cuff surrounding an arm with sufficient pressure to prevent blood flow in the local main artery. This pressure is gradually released until the moment that the blood begins to flow through the artery, the measurement of which determines the systolic pressure. Pulse rate is also sensed at this time. The measurement taken when the blood flow is no longer restricted determines the diastolic pressure. This complete measurement cycle is performed automatically with a pump, cuff, valve, and pressure sensor. The signal from the pressure sensor is conditioned with an op-amp circuit or by an instrumentation amplifier before data conversion by an analogto-digital converter (ADC). The systolic pressure, diastolic pressure, and pulse rate are then calculated in the digital domain using a method Upper-arm blood pressure monitor Wrist blood pressure monitor

Autologous cord blood transfusion.  

PubMed

Newborn piglets were exsanguinated (60% of blood volume) and retransfused 1 h later. One test group received adult pig red blood cells, the other piglet cord blood cells; controls were infused with plasma. While all controls died, satisfactory results were achieved in piglets transfused with either adult or foetal blood. The feasibility of collecting human cord blood for transfusion was assessed in 100 samples of human cord blood. Blood was collected aseptically and aerobic and anaerobic cultures set up. All samples of cord blood were sterile, and all were Mycoplasma negative. Coagulation parameters were analysed in eight cord plasma samples stored at -20 degrees C for 45 days. No significant abnormalities were found immediately after birth or after storage. PMID:7949798

Manufacture of pooled platelets in additive solution and storage in an ELX container after an overnight warm temperature hold of platelet-rich plasma.  

PubMed

The processing of whole blood-derived platelet-rich plasma (PRP) to a platelet concentrate and platelet-poor plasma is currently performed within 8 hours to comply with the requirements to manufacture fresh frozen plasma. Maintaining PRP at room temperature for a longer period can have the advantage of shifting the completion of component manufacture onto day shifts. Pairs of ABO-identical prepooled platelets were manufactured by the PRP method, using the current approach with platelet storage in a CLX HP container (Pall Medical, Covina, CA) and plasma, or a novel approach with an 18- to a 24-hour room temperature hold of the PRP and the manufacture of pooled platelets in a glucose-containing additive solution (AS) and storage in a new ELX container (Pall Medical). Standard in vitro assays were performed on days 2, 5, and 7. The results showed that the AS platelets in ELX have in vitro characteristics that are equivalent or superior to those of the standard product. PMID:21917688

Hand-Held Color Meters Based on Interference Filters  

NASA Technical Reports Server (NTRS)

Small, inexpensive, hand-held optoelectronic color-measuring devices based on metal-film/dielectric-film interference filters are undergoing development. These color meters could be suitable for use in a variety of applications in which there are requirements to quantify or match colors for aesthetic purposes but there is no need for the high spectral resolution of scientific-grade spectrometers. Such applications typically occur in the paint, printing, and cosmetic industries, for example. The figure schematically depicts a color meter of this type being used to measure the color of a sample in terms of the spectrum of light reflected from the sample. Light from a white source (for example, a white light-emitting diode) passes through a collimating lens to the sample. Another lens collects some of the light reflected from the sample and focuses the light onto the input end of optical fiber. Light emerging from the output end of the optical fiber illuminates an array of photodetectors covered with metal/dielectric-film interference filters like those described in Metal/Dielectric-film Interference Color Filters (NPO-20217), NASA Tech Briefs, Vol. 23, No. 2 (February 1999), page 70. Typically, these are wide-band-pass filters, as shown at the bottom of the figure. The photodetector array need not be of any particular design: it could be something as simple as an assembly containing several photodiodes or something as elaborate as an active-pixel sensor or other imaging device. What is essential is that each of the photodetectors or each of several groups of photodetectors is covered with a metal/dielectric-film filter of a different color. In most applications, it would be desirable to have at least three different filters, each for a spectral band that contains one of the three primary additive red, green, and blue colors. In some applications, it may be necessary to have more than three different color filters in order to characterize subtle differences in color (or in the sensation of color) that cannot be characterized with sufficient precision by use of the primary colors alone.

Blood and blood products usage in Maputo.  

PubMed

We studied retrospectively a sample of 521 order forms for blood and blood products transfusion, among the 25,845 requests sent to the Maputo Central Hospital's Blood Bank., from March 1992 to February 1993. The Paediatrics Department ordered nearly half (47.2 pc); Surgery ranked second (16.9 pc), followed by Gynaecology-Obstetrics (1604 pc) and the Intensive Care Unit (15.7 pc). Medicine issued only 3.8 pc of the orders. Children under five years old were the target of most (43.3 pc) orders; among them 71.1 pc were under three years old. The volumes ordered most often were 500 ml (25 pc) and 1,000 ml (18.3 pc). Fifty seven pc of orders were for packed blood cells, followed by whole blood (34.7 pc). Orders for fresh frozen plasma accounted for only 6.9 pc. Anaemia was the diagnosis mentioned most often (59.3 pc). In 27.1 pc of orders for anaemia, malaria was the specific cause. Haemoglobin values of transfusions' recipients ranged between 1 and 14.7 g/dL. Most (72.9 pc) were below 6 g/dL. Orders for use during the perioperative period accounted for 22.8 pc. On the basis of our results, we suggest that the Surgery and Gynaecology-Obstetrics Departments should review their policies on haemotherapy, particularly for the peri-operative method. We also suggest creation of a transfusion advisory committee, to establish guidelines and implementation mechanisms for the rational use of blood. Combined with continuous education of blood therapy prescribers, this may lead to a reduction of unnecessary transfusions and to the subsequent reduction of blood-borne disease transmission in Maputo.

Effects of intravenous delivery systems on infused red blood cells.  

PubMed

The effects of various intravenous delivery systems on the integrity of infused red blood cells (RBCs) were studied. Using a factorial design, whole blood and packed RBCs were infused through i.v. delivery systems employing various combinations of i.v. tubing diameter and length, needle gauge, infusion rate (5 and 50 ml/hr), type of infusion pump (piston, diaphragm, or peristaltic operation), and type of blood product. The age and temperature of the blood filter used were held constant. A 5-ml sample of the blood product obtained during each experimental run was analyzed for plasma free-hemoglobin to assess the degree of hemolysis. Osmotic fragility of the RBCs was evaluated by measuring the percentage of hemolysis in the blood products in various concentrations of sodium chloride solution. Type of blood product and i.v. pump were the only variables significantly influencing RBC hemolysis. In both blood products, a greater degree of hemolysis occurred with the peristaltic-type pump than with the other types of pumps. In packed RBCs, the diaphragm-type pump produced greater hemolysis than the piston-type pump, but hemolysis was similar in whole-blood samples. Regardless of the type of pump, more hemolysis occurred in whole blood at the 5-ml/hr infusion rate than at the 50-ml/hr rate, but the converse was true in packed RBCs. Samples of both blood products were less osmotically fragile than their respective controls at sodium chloride concentrations ranging from 0.30 to 0.50%.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:6702849

Conformal cytocompatible ferrite coatings facilitate the realization of a nanovoyager in human blood.  

PubMed

Controlled motion of artificial nanomotors in biological environments, such as blood, can lead to fascinating biomedical applications, ranging from targeted drug delivery to microsurgery and many more. In spite of the various strategies used in fabricating and actuating nanomotors, practical issues related to fuel requirement, corrosion, and liquid viscosity have limited the motion of nanomotors to model systems such as water, serum, or biofluids diluted with toxic chemical fuels, such as hydrogen peroxide. As we demonstrate here, integrating conformal ferrite coatings with magnetic nanohelices offer a promising combination of functionalities for having controlled motion in practical biological fluids, such as chemical stability, cytocompatibility, and the generated thrust. These coatings were found to be stable in various biofluids, including human blood, even after overnight incubation, and did not have significant influence on the propulsion efficiency of the magnetically driven nanohelices, thereby facilitating the first successful "voyage" of artificial nanomotors in human blood. The motion of the "nanovoyager" was found to show interesting stick-slip dynamics, an effect originating in the colloidal jamming of blood cells in the plasma. The system of magnetic "nanovoyagers" was found to be cytocompatible with C2C12 mouse myoblast cells, as confirmed using MTT assay and fluorescence microscopy observations of cell morphology. Taken together, the results presented in this work establish the suitability of the "nanovoyager" with conformal ferrite coatings toward biomedical applications. PMID:24641110

Use of blood and blood products.  

PubMed

It is sometimes necessary for the practitioner to transfuse the ruminant with whole blood or plasma. These techniques are often difficult to perform in practice, are time-consuming, expensive, and stressful to the animal. Acute loss of 20% to 25% of the blood volume will result in marked clinical signs of anemia, including tachycardia and maniacal behavior. The PCV is only a useful tool with which to monitor acute blood loss after intravascular equilibration with other fluid compartments has occurred. An acutely developing PCV of 15% or less may require transfusion. Chronic anemia with PCV of 7% to 12% can be tolerated without transfusion if the animal is not stressed and no further decline in erythrocyte mass occurs. Seventy-five percent of transfused bovine erythrocytes are destroyed within 48 hours of transfusion. A transfusion rate of 10 to 20 mL/kg recipient weight is necessary to result in any appreciable increase in PCV. A nonpregnant donor can contribute 10 to 15 mL of blood/kg body weight at 2- to 4-week intervals. Sodium citrate is an effective anticoagulant, but acid citrate dextrose should be used if blood is to be stored for more than a few hours. Blood should not be stored more than 2 weeks prior to administration. Heparin is an unsuitable anticoagulant because the quantity of heparin required for clot-free blood collection will lead to coagulation defects in the recipient. Blood cross-matching is only rarely performed in the ruminant. In field situations, it is advisable to inject 200 mL of donor blood into the adult recipient and wait 10 minutes. If no reaction occurs, the rest of the blood can probably be safely administered as long as volume overload problems do not develop. Adverse reactions are most commonly seen in very young animals or pregnant cattle. Signs of blood or plasma transfusion reaction include hiccoughing, tachycardia, tachypnea, sweating, muscle tremors, pruritus, salivation, cough, dyspnea, fever, lacrimation, hematuria, hemoglobinuria, collapse, apnea, and opisthotonos. Intravenous epinephrine HCl 1:1000 can be administered (0.2 to 0.5 mL) intravenously or (4 to 5 mL) intramuscularly (preferable) if clinical signs are severe. Pretreatment with antipyretics and slowing the administration rate may decrease the febrile response. Blood or plasma administered too rapidly will also result in signs of cardiovascular overload, acute heart failure, and pulmonary hypertension and edema. Furosemide and slower administration of blood or plasma should alleviate this problem. Administration rates have been suggested starting from 10 mL/kg/hr; faster rates may be necessary in peracute hemorrhage. Plasma should be administered when failure of absorption of passive maternal antibody has occurred or when protein-loosing enteropathy or nephropathy results in a total protein of less than 3 g/dL or less than 1.5 g albumin/dL. Plasma can be stored at household freezer temperatures (-15 to -20 degrees C) for a year; coagulation factors will be destroyed after 2 to 4 months when stored in this manner. To maintain viability of coagulation factors, plasma must be stored at -80 degrees C for less than 12 months. When administering plasma, a blood donor set with a built-in filter should always be used. When bovine plasma is thawed, precipitants form in the plasma and infusion of these microaggregates may result in fatal reactions in the recipient. PMID:10573816

Blood banking in China.  

PubMed

While transfusion-transmissible diseases, including AIDS and viral hepatitis, continue to spread especially in developing countries, the issue of safeguarding the world's blood supply is of paramount importance. China houses more than 20% of the earth's population, and thus its blood supply has the potential to affect the global community. In recent years, Chinese blood centres have tried to improve the nation's blood safety. Although substantial progress has already been made, many daunting difficulties remain. Traditional cultural barriers need to be overcome to successfully mobilise volunteer blood donors. Gaps in information and technology still need to be closed. Insufficiency of economic resources also restrict the blood bank industry. Other developing countries face many of the same challenges as China. PMID:12480443

Drying drops of blood  

NASA Astrophysics Data System (ADS)

The drying of a drop of human blood is fascinating by the complexity of the physical mechanisms that occur as well as the beauty of the phenomenon which has never been previously evidenced in the literature. The final stage of full blood evaporation reveals for a healthy person the same regular pattern with a good reproducibility. Other tests on anemia and hyperlipidemic persons were performed and presented different patterns. By means of digital camera, the influence of the motion of red blood cells (RBCs) which represent about 50% of the blood volume, is revealed as well as its consequences on the final stages of drying. The mechanisms which lead to the final pattern of dried blood drops are presented and explained on the basis of fluid and solid mechanics in conjunction with the principles of hematology. Our group is the first to evidence that the specific regular patterns characteristic of a healthy individual do not appear in a dried drop of blood from a person with blood disease. Blood is a complex colloidal suspension for which the flow motion is clearly non-Newtonian. When drops of blood evaporate, all the colloids are carried by the flow motion inside the drop and interact.

Hand-held based near-infrared optical imaging devices: a review.  

PubMed

Near-infrared (NIR) optical imaging is a non-invasive and non-ionizing modality that is emerging as a diagnostic/prognostic tool for breast cancer and other applications related to functional brain mapping. In recent years, hand-held based optical imaging devices are developed for clinical translation of the technology, as opposed to the various bulky optical imagers available. Herein, we review the different hand-held based NIR devices developed to date, in terms of the measurement techniques implemented (continuous wave, time or frequency-domain), the imaging methods used, and the specific applications towards which they were applied. The advantages and disadvantages of the different hand-held optical devices are described and also compared with respect to a novel hand-held based device currently developed in our Optical Imaging Laboratory towards three-dimensional tomography studies.

Indications for blood and blood product transfusion  

PubMed Central

Transfusion of blood products carries certain inherent risks and hence it should be undertaken only if it improves patient outcome. A review of the literature was carried out to find the indications and effects of transfusion on morbidity and mortality of patients. There is high-quality evidence showing that restrictive blood transfusion with a transfusion trigger of haemoglobin of 7-8 g/dl or the presence of symptoms of anaemia is safe and not associated with increased mortality compared with liberal transfusion. Thus, restrictive strategy is strongly recommended in surgical and critically ill-patients. There is moderate evidence for the use of plasma and platelet transfusion in patients receiving massive blood transfusion. There is not enough evidence to support the use of plasma, platelets and cryoprecipitate in any other clinical setting. Retrospective studies show improved survival after high plasma and platelet to red blood cell ratio of 1:1:1, but this has not been confirmed in randomised trials.

Blood Pressure Checker  

NASA Technical Reports Server (NTRS)

An estimated 30 million people in the United States have high blood pressure, or hypertension. But a great many of them are unaware of it because hypertension, in its initial stages, displays no symptoms. Thus, the simply-operated blood pressure checking devices now widely located in public places are useful health aids. The one pictured above, called -Medimax 30, is a direct spinoff from NASA technology developed to monitor astronauts in space. For manned space flights, NASA wanted a compact, highly-reliable, extremely accurate method of checking astronauts' blood pressure without the need for a physician's interpretive skill. NASA's Johnson Space Center and Technology, Inc., a contractor, developed an electronic sound processor that automatically analyzes blood flow sounds to get both systolic (contracting arteries) and diastolic (expanding arteries) blood pressure measurements. NASA granted a patent license for this technology to Advanced Life Sciences, Inc., New York City, manufacturers of Medimax 30.

Human blood cells at microgravity: the NASA Initial Blood Storage Experiment.  

PubMed

The Initial Blood Storage Experiment (IBSE) probed the behavior of human red cells, white cells, and platelets during exposure to microgravity for 6 days and 2 hours on a National Aeronautics and Space Administration (NASA) shuttle mission, named STS 61-C, which was launched on January 12, 1986. IBSE involved carefully controlled comparisons between two identical sets of blood cells, one exposed to microgravity and the other held on the ground. Specially designed and fabricated, electrically powered environmental chambers provided appropriate environmental temperatures and air flow to support cell metabolism throughout the experiment. To circumvent the need for constant agitation of platelets during storage, a new thin-layer compression method for platelet preservation was developed. Blood cell samples were allocated to the two arms of the experiment, microgravity and earth gravity, by blind assignment. Moreover, to ensure unbiased assessment of the experiment's findings, postexperiment samples for measurement were identified by code. To optimize the chances of detecting possible gravitational effects, a wide array of measurements of cellular function, morphology, metabolism, and immunology were made. Analysis of variance was used in analyzing the data. The most striking finding was that platelets displayed markedly superior structural and functional integrity at microgravity. Granulocytes held on the ground were preserved slightly better than those that orbited in the shuttle, whereas red cells displayed few effects that were attributable to the gravitational variable. Polyvinylchloride-di-(2-ethylhexyl)phthalate (PVC-DEHP) was the plastic of choice for storage of red cells, while PVC-trioctyltrimellitate (TOTM) was superior to PVC-DEHP and polyolefin (PO) for platelets.

Validation and development of an immunonephelometric assay for the determination of alpha-1 antitrypsin levels in dried blood spots from patients with COPD*  

PubMed Central

OBJECTIVE: To validate and develop an immunonephelometric assay for the determination of alpha-1 antitrypsin (AAT) levels in dried blood spots from COPD patients in Brazil. METHODS: We determined AAT levels in serum samples and dried blood spots from 192 COPD patients. For the preparation of dried blood spots, a disk (diameter, 6 mm) was placed into a tube, eluted with 200 µL of PBS, and stored overnight at 4ºC. All of the samples were analyzed by immunonephelometry in duplicate. We used the bootstrap resampling method in order to determine a cut-off point for AAT levels in dried blood spots. RESULTS: The correlation coefficient between the AAT levels in serum samples and those in dried blood spots was r = 0.45. For dried blood spots, the cut-off value was 2.02 mg/dL (97% CI: 1.45-2.64 mg/dL), with a sensitivity, specificity, positive predictive value, and negative predictive value of 100%, 95.7%, 27.2%, and 100%, respectively. CONCLUSIONS: This method for the determination of AAT levels in dried blood spots appears to be a reliable screening tool for patients with AAT deficiency. PMID:24310627

Both rhythmic and "resistive" (weight lifting) exercise training can produce modest decreases in resting blood pressure. The next logical point along an exercise continuum consisting of different proportions of rhythmic and isometric efforts is a strictly isometric effort. The purpose of these studies was to assess the effects of isometric, handgrip exercise training on resting blood pressure. To avoid the extreme pressor responses elicited by fatiguing isometric efforts, the isometric exercise training used in this study consisted of brief handgrip contractions separated by rest periods. Modest repeated rises in systolic and diastolic pressures therefore served as the putative stimuli for training adaptations in resting blood pressures. Human subjects in study 1 trained with four, 2-min isometric handgrip contractions with 3-min rests between contractions. The intensity of the contractions was equal to 30% of their maximal effort for each day. The bouts of isometric exercise were performed three times per week for 8 wk. Study 2 training consisted of four contractions of 50% of maximum effort held for a duration of 45 s with 1-min rests. These were performed 5 d.wk-1 for 5 wk. In Study 1, all eight trained subjects had a significant decline in both systolic and diastolic resting blood pressures, with group averages of 12.5 and 14.9 mm Hg, respectively. Seven matched control subjects who did not train had no change in resting pressures. In study 2, subjects were trained in their home or workplace and experienced significant mean declines in resting systolic and diastolic pressures of 9.5 and 8.9 mm Hg.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:1501558

Initial blood storage experiment  

NASA Technical Reports Server (NTRS)

The possibility of conducting experiments with the formed elements of the blood under conditions of microgravity opens up important opportunities to improve the understanding of basic formed element physiology, as well as, contribution to improved preservation of the formed elements for use in transfusion. The physiological, biochemical, and physical changes of the membrane of the erythrocyte, platelet, and leukocyte was studied during storage under two specific conditions: standard blood bank conditions and microgravity, utilizing three FDA approved plastic bags. Storage lesions; red cell storage on Earth; platelet storage on Earth; and leukocyte storage Earth were examined. The interaction of biomaterials and blood cells was studied during storage.

Blood Pressure Control  

NASA Technical Reports Server (NTRS)

Engineering Development Laboratory developed a system for the cardiovascular study of weightless astronauts. This was designed to aid people with congestive heart failure and diabetes. While in space, astronauts' blood pressure rises, heart rate becomes unstable, and there are sometimes postflight lightheadedness or blackouts. The Baro-Cuff studies the resetting of blood pressure. When a silicone rubber chamber is strapped to the neck, the Baro-Cuff stimulates the carotid arteries by electronically controlled pressure application. Blood pressure controls in patients may be studied.

We identified an educational deficit among clients at a community health clinic regarding the latest cervical cancer screening recommendations. A literature search on Pap testing and problems with compliance or screening indicated multiple barriers to cervical cancer screening. Education, health promotion and the use of a hand-held health card/record were identified as methods to educate women regarding cervical cancer prevention. We developed a hand-held Pap test card to be similar to an immunization card. The card was designed to fulfill the needs of both clients and practitioners. PMID:24939198

Measurement of Discharge Current through Hand-held Metal Piece from Charged Human Body  

NASA Astrophysics Data System (ADS)

Discharge currents through a hand-held metal piece from a charged human body were measured with respect to approaching speeds and charge voltages. A circuit approach for calculating the discharge current has also been shown. As a result, we have found that in case of 300 V charge voltage, the current waveform is not affected by the metal piece approaching speed, while in case of 800 V charge voltage, the fast approach gives the higher current peak. These current waveforms can be predicted from the time invariant spark resistance and the measured frequency characteristics of a human body impedance seen from a hand-held metal piece.

Surgical wound healing in radio-tagged adult Pacific lamprey Entosphenus tridentatus held on different substrata  

USGS Publications Warehouse

Radio-tagged adult Pacific lamprey Entosphenus tridentatus held in a raceway with Plexiglas-lined walls and bottom healed more slowly and retained sutures longer than fish held in an all-concrete raceway or one with Plexiglas walls and a cobble-lined bottom. On all substrata, healing depended on when sutures were lost, and fish that lost their sutures in <14 days post-surgery healed faster than those that kept sutures longer. Long-term suture retention led to tissue trauma, infection and poor survival.

Blood Vessel Tension Tester  

NASA Technical Reports Server (NTRS)

In the photo, a medical researcher is using a specially designed laboratory apparatus for measuring blood vessel tension. It was designed by Langley Research Center as a service to researchers of Norfolk General Hospital and Eastern Virginia Medical School, Norfolk, Virginia. The investigators are studying how vascular smooth muscle-muscle in the walls of blood vessels-reacts to various stimulants, such as coffee, tea, alcohol or drugs. They sought help from Langley Research Center in devising a method of measuring the tension in blood vessel segments subjected to various stimuli. The task was complicated by the extremely small size of the specimens to be tested, blood vessel "loops" resembling small rubber bands, some only half a millimeter in diameter. Langley's Instrumentation Development Section responded with a miniaturized system whose key components are a "micropositioner" for stretching a length of blood vessel and a strain gage for measuring the smooth muscle tension developed. The micropositioner is a two-pronged holder. The loop of Mood vessel is hooked over the prongs and it is stretched by increasing the distance between the prongs in minute increments, fractions of a millimeter. At each increase, the tension developed is carefully measured. In some experiments, the holder and specimen are lowered into the test tubes shown, which contain a saline solution simulating body fluid; the effect of the compound on developed tension is then measured. The device has functioned well and the investigators say it has saved several months research time.

Blood and War  

PubMed Central

SUMMARY In 1894 Ulsterman and pathologist Almroth Wright described the citation of blood. Twenty-one years later it was introduced into wartime and clinical practice. Harvard Medical School had a large part in providing Colonel Andrew Fullerton, later Professor of Surgery, Queen's Belfast, with the intellectual and practical help for the Allies to deploy blood on the post-Somme Western Front and in Salonika. The key investigators and clinicians were Americans and Canadians who with Fullerton and Wright instructed the Allies. The key enablers were two Harvard-trained surgeons surnamed Robertson—Oswald H. (“Robby”) and L. Bruce (no relation). Physician Roger I. Lee of Harvard, surgeon George W Crile of Cleveland, Peyton Rous of the Rockefeller Institute and Richard Lewisohn of Mount Sinai Hospital, both located in the Upper East Side of New York City, played key roles. By Armistice in 1918, indirect citrated nutrient-enhanced blood transfusion was widely used by the Allies. Geoffrey Keynes was taught the techniques of blood transfusion by Dr. Benjamin Harrison Alton of Harvard at a Casualty Clearing Station near Albert at the time of the Battle of Passchendaele. Professor “Robby” Robertson, DSO, Sir Geoffrey Keynes and Sir Thomas Houston established blood banking. PMID:22375087

White blood cells and bone marrow are stored for future use by leukemia patients as a result of Goddard and Jet Propulsion Laboratory expertise in electronics and cryogenics. White blood cell and bone marrow bank established using freezing unit. Freezing unit monitors temperature of cells themselves. Thermocouple placed against polyethylene container relays temperature signals to an electronic system which controls small heaters located outside container. Heaters allow liquid nitrogen to circulate at constant temperature and maintain consistent freezing rate. Ability to freeze, store, and thaw white cells and bone marrow without damage is important in leukemia treatment.

Responses of blood glucose and C-peptide to five Chinese starchy foods.  

PubMed

Forty-nine patients with non-insulin-dependent diabetes mellitus (NIDDM) were randomly divided into four groups (10-18 patients per group) to compare the responses of blood glucose and C-peptide to some Chinese starchy foods. Ten healthy subjects were used as controls. After an overnight fast, the blood samples were drawn at fasting and 30, 60, 120, 180 minutes postprandially to measure plasma glucose and serum C-peptide levels. Bun, which was made from refined wheat flour and similar to white bread, was used in the assessment as the reference food. Other test foods included rice, lotus seed, seed of gordon euryale, and rhizome of common yam. There was only one kind of food in each test meal, and each serving contained 50 g of carbohydrate. With both glycaemic index (GI) and C-peptide index (CI) of bun set as 100 in this study, the GI and CI respectively were: rice 89 and 91; lotus seed 62 and 72; seed of gordon euryale 102 and 102; rhizome of common yam 103 and 95. The GI and CI of lotus seed were significantly lower than those of other test foods. It appears that lotus seed may have a beneficial effect in NIDDM patients, and may be one of the more appropriate foods for diabetic patients. PMID:24351331

Blood Flow in Arteries  

NASA Astrophysics Data System (ADS)

Blood flow in arteries is dominated by unsteady flow phenomena. The cardiovascular system is an internal flow loop with multiple branches in which a complex liquid circulates. A nondimensional frequency parameter, the Womersley number, governs the relationship between the unsteady and viscous forces. Normal arterial flow is laminar with secondary flows generated at curves and branches. The arteries are living organs that can adapt to and change with the varying hemodynamic conditions. In certain circumstances, unusual hemodynamic conditions create an abnormal biological response. Velocity profile skewing can create pockets in which the direction of the wall shear stress oscillates. Atherosclerotic disease tends to be localized in these sites and results in a narrowing of the artery lumena stenosis. The stenosis can cause turbulence and reduce flow by means of viscous head losses and flow choking. Very high shear stresses near the throat of the stenosis can activate platelets and thereby induce thrombosis, which can totally block blood flow to the heart or brain. Detection and quantification of stenosis serve as the basis for surgical intervention. In the future, the study of arterial blood flow will lead to the prediction of individual hemodynamic flows in any patient, the development of diagnostic tools to quantify disease, and the design of devices that mimic or alter blood flow. This field is rich with challenging problems in fluid mechanics involving three-dimensional, pulsatile flows at the edge of turbulence.

Blood: The Stuff of Life  

NSDL National Science Digital Library

The purpose of this lesson is to teach students about blood and its components while instilling an appreciation of its importance for survival. The lesson takes a step-by-step approach to determining the "recipe" for blood while introducing students to important laboratory techniques like centrifugation and microscopy, as well as some diseases of cell types found in blood. It also highlights the importance of donating blood by explaining basic physiological concepts and the blood donation procedure. There are no formal prerequisites, but students should be comfortable with converting weight units. The only materials needed are a calculator and paper, and it would be helpful to print the downloadable color PDF files of blood smear images. During the breaks, students are asked to estimate and then calculate the amount of blood in their body, identify cell types in a blood smear, and discuss the composition of blood with their neighbor. The lesson can be completed within a 50-minute class session.

Pig and Goat Blood as Substitutes for Sheep Blood in Blood-Supplemented Agar Media  

PubMed Central

In many developing countries sheep and horse blood, the recommended blood supplements in bacteriological media, are not readily available, whereas pig and goat blood are. Therefore, this study examined the use of pig and goat blood as potential substitutes for sheep blood in blood-supplemented bacteriologic media commonly used in clinical microbiology laboratories. In general, the growth characteristics and colony morphologies of a wide range of aerobic and anaerobic bacteria and Candida albicans were similar on media containing pig, goat, and sheep blood, although differences were found. Enterococcus sp. uniformly produced alpha-hemolysis when incubated in CO2, but in anaerobic conditions the hemolysis varied. In contrast, beta-hemolytic streptococci produced identical hemolytic reactions on all three media. Synergistic hemolysis was not observed on pig blood agar in the CAMP test nor on goat blood agar in the reverse CAMP test. The preparation of chocolate agar (heated) with pig blood required heating to a higher temperature than with sheep or goat blood to yield suitable growth of Haemophilus species. In general, we conclude that pig and goat blood are suitable alternatives to sheep blood for use in bacteriological media in settings where sheep and horse blood are not readily available.

Optically measured microvascular blood flow contrast of malignant breast tumors.  

PubMed

Microvascular blood flow contrast is an important hemodynamic and metabolic parameter with potential to enhance in vivo breast cancer detection and therapy monitoring. Here we report on non-invasive line-scan measurements of malignant breast tumors with a hand-held optical probe in the remission geometry. The probe employs diffuse correlation spectroscopy (DCS), a near-infrared optical method that quantifies deep tissue microvascular blood flow. Tumor-to-normal perfusion ratios are derived from thirty-two human subjects. Mean (95% confidence interval) tumor-to-normal ratio using surrounding normal tissue was 2.25 (1.92-2.63); tumor-to-normal ratio using normal tissues at the corresponding tumor location in the contralateral breast was 2.27 (1.94-2.66), and using normal tissue in the contralateral breast was 2.27 (1.90-2.70). Thus, the mean tumor-to-normal ratios were significantly different from unity irrespective of the normal tissue chosen, implying that tumors have significantly higher blood flow than normal tissues. Therefore, the study demonstrates existence of breast cancer contrast in blood flow measured by DCS. The new, optically accessible cancer contrast holds potential for cancer detection and therapy monitoring applications, and it is likely to be especially useful when combined with diffuse optical spectroscopy/tomography.

Clearance monitoring using hand-held devices: operational implementation and challenges.  

PubMed

Clearance monitoring includes all measures taken and measurements performed to ensure that all pertinent regulatory conditions are met for clearance of waste material. For bulk material, only a limited number of monitoring techniques are feasible for providing the necessary proof of compliance in the time frames and at costs commensurate with operator and regulator expectations for decommissioning projects. Operationally, measurements using hand-held devices, such as contamination monitors using scintillator or proportional counter technology, might provide sufficiently short response times at acceptable accuracies to segregate the waste streams according to their level of contamination and allowing for a decision on their further processing. Recognizing the various limitations hand-held devices might display in bulk material screening during clearance monitoring measurements, the detection limits with respect to material self-attenuation and non-homogenous activity distributions have been investigated.

Hand-held cow horn: resurgence of an old arm or apotential terrorist weapon  

PubMed Central

Abstract: A 23 year old man presented with intestinal evisceration from stab injury to the left side of the abdomen with a hand-held cow horn at a local night party. He complained of severe abdominal pain and bleeding at the site of injury. He was hemodynamically stable. At emergency exploration, the eviscerated bowel was viable with no adjacent mesenteric tear. Other intra abdominal organs were normal. The eviscerated bowel was lavaged and reduced into the abdomen through the 7cm anterior abdominal wall laceration. The laceration was repaired and abdomen closed in layers. Post operative recovery was uneventful. The hand-held cow horn can easily be concealed and may pass through security checks undetected. It should be added to the ever increasing list of weapons of small scale terror. PMID:21502787

The hand-held 3D laser scanner sold in the market is appealing for its port and convenient to use, but price is expensive. To develop such a system based cheap devices using the same principles as the commercial systems is impossible. In this paper, a simple hand-held 3D laser scanner is developed based on a volume reconstruction method using cheap devices. Unlike convenient laser scanner to collect point cloud of an object surface, the proposed method only scan few key profile curves on the surface. Planar section curve network can be generated from these profile curves to construct a volume model of the object. The details of design are presented, and illustrated by the example of a complex shaped object.

Modelling pulmonary blood flow  

PubMed Central

Computational model analysis is a method that has been used widely to understand and interpret complexity of interactions in the pulmonary system. Pulmonary blood transport is a multi-scale phenomenon that involves scale-dependent structure and function, therefore requiring different model assumptions for the microcirculation and the arterial or venous flows. The blood transport systems interact with the surrounding lung tissue, and are dependent on hydrostatic pressure gradients, control of vasoconstriction, and the topology and material composition of the vascular trees. This review focuses on computational models that have been developed to study the different mechanisms contributing to regional perfusion of the lung. Different models for the microcirculation and the pulmonary arteries are considered, including fractal approaches and anatomically-based methods. The studies that are reviewed illustrate the different complementary approaches that can be used to address the same physiological question of flow heterogeneity. PMID:18434260

[Emergency blood picture].

Assessment of peripheral blood counts and blood film analysis are frequently performed as diagnostic procedures in emergency medicine. Far fewer situations exist, however, in which these analyses are the main clue in establishing an emergency diagnosis. Artifacts can lead to wrong diagnosis, e.g. pseudo-thrombocytopenia, which is defined as a low platelet count resulting from a laboratory artifact. Severe neutropenia (agranulocytosis) and extreme hyperleukocytosis, as well as suspicion of acute leukemia, require a rapid diagnostic work-up. A newly detected anemia should not necessarily be treated by packed red cell transfusions. The decision whether an anemic patient ought to receive transfusions should be based on the speed with which the anemia has developed, as well as on clinical judgement. As a rule a chronic anemia patient with hemoglobin above 70 g/l does not need transfusions. An uncritical transfusion policy can even cause emergencies, e.g. in patients with megaloblastic anemia or in anemic multiple myeloma patients with a hyperviscosity syndrome. An elevated hematocrit requires prompt further investigations. This is of utmost importance if one considers the diagnosis of polycythemia vera rubra, a disease in which patients are particularly prone to thrombotic complications. Fragmented red cells (schistocytes) on peripheral blood smears constitute a cardinal diagnostic clue for the detection of microangiopathic hemolytic anemias (MAHA), in particular for the diagnosis of the life-threatening thrombotic thrombocytopenic purpura (TTP) and hemolytic uremic syndrome (HUS). Malaria is another example for a chief role of blood smears examination in achieving a rapid diagnosis. If one encounters an unexpected severe thrombocytopenia, a marrow examination reveals whether it is due to rapid peripheral destruction, or due to a marrow failure. Furthermore, in any patients with an unanticipated thrombocytopenia, a disseminated intravascular coagulation and a MAHA should be ruled out. Heparin-induced thrombocytopenia is a rare, but possibly fatal complication of therapy with heparins. PMID:8488374

Hand-held computing in the patient care setting: a pilot project.  

PubMed Central

Direct patient care has not fully benefited from a number of recent advances in modern technology. Many of the normal data collections tasks carried out by care providers are still done with manual, error-prone procedures. In addition, the ability to consolidate or represent patient data in a meaningful and timely fashion as required by managed care expectations is unavailable. The reported work attempts to address these problems with the application of new hand-held computing technology. PMID:8563378

THE VALIDITY OF PLANTARFLEXOR STRENGTH MEASURES OBTAINED THROUGH HAND?HELD DYNAMOMETRY MEASUREMENTS OF FORCE  

PubMed Central

Purpose/Background: Hand?held dynamometers are commonly used to assess plantarflexor strength during rehabilitation. The purpose of this study was to determine the concurrent validity of measuring plantarflexion force using a hand?held dynamometer (HHD) as compared to an electromechanical dynamometer as the gold standard. The hypothesis was that plantarflexor forces obtained using a hand?held dynamometer would not show absolute agreement with a criterion standard. Design: Concurrent validity assessment for a diagnostic strength testing device. Setting: Institutional clinic and research laboratory Participants: Volunteer sample of healthy university students (N=20, 10 women, 10 men; 25.9±4.1 years). Main Outcome Measure(s): Maximal plantarflexion strength was measured using both a HHD and an electromechanical dynamometer (EMD) as a criterion measure. Results: Plantarflexor force measures with the HHD were significantly different (p<0.01) and not correlated with plantarflexor forces measured using the EMD for either limb (R2 ? 0.09). Conclusions: Plantarflexor strength measurements acquired using HHD are different from those acquired using an EMD and are likely influenced by the strength of the examiner. Level of Evidence: Prospective cohort study, level II PMID:24377068
