    Intimate Partner Violence (IPV) is a global public health problem. IPV prevalence in Indonesia has been estimated to be less than 1%, based on reported cases. It is likely that IPV prevalence is underreported in Indonesia, as it is in many other countries. Screening for IPV has been found to increase IPV identification, but no screening tools are in use in Indonesia. The aim of this study was to test the translated Woman Abuse Screening Tool (WAST) for detecting IPV in Indonesia. The WAST was tested against a diagnostic interview by a trained psychologist on 240 women attending two Primary Health Centers in Jakarta. IPV prevalence and the reliability, sensitivity, and specificity of the WAST were estimated. Prevalence of IPV by diagnostic interview was 36.3%, much higher than published estimates. The most common forms of IPV identified were psychological (85%) and physical abuse (24%). Internal reliability of the WAST was high (α = .801). A WAST score of 13 (out of 24) is the recommended cutoff for identifying IPV, but only 17% of the Indonesian sample scored 13 or higher. Test sensitivity of the WAST with a cutoff score of 13 was only 41.9%, with a specificity of 96.8%. With a cutoff score of 10, the sensitivity improved to 84.9%, while the specificity decreased to 61.0%. Use of the WAST with a cutoff score of 10 provides good sensitivity and reasonable specificity and would provide a much-needed screening tool for use in Indonesia. Although a lower cutoff would yield a greater proportion of false positives, most of the true cases would be identified, increasing the possibility that women experiencing abuse would receive needed assistance.

    According to the Italian laws, some categories of workers entrusted with duties possibly constituting a threat to security, physical safety, and health of third parties have to be screened to exclude the use/abuse of the following drugs of abuse: opiates, cocaine, cannabinoids, amphetamine, methamphetamine, 3,4-methylenedioxymethamphetamine, methadone, and buprenorphine. Toxicological tests can be performed with urinary on-site rapid screening devices, provided that sensitivities up to specified cutoffs are ensured. The present study reports performances, in terms of sensitivity, specificity, and accuracy, of an automatic on-site test and of an FPIA-based device, using gas chromatography/mass spectrometry (GC/MS) as a reference methodology. Three levels of concentration were tested, corresponding to the cutoff and to 2 and 3 times the limits, respectively. In terms of sensitivities, neither the on-site nor the benchtop instrumentations gave positive results, since values of zero percentage were obtained for concentrations up to 2-fold the limits. Even if good results were obtained in terms of specificity and accuracy by both devices, none of them seem to be adequate for the current application to the toxicological screening at workplaces. In fact, a rapid screening device can be used for drug tests provided that it ensures sensitivity at the prescribed cutoffs. Data showed that such is completely rejected and a more sensitive instrumentation should be preferred. PMID:21992470

    We assessed the Chinese version of the Drug Abuse Screening Test (DAST-10) for identifying illicit drug use during pregnancy among Chinese population. Chinese pregnant women attending their first antenatal visit or their first unbooked visit to the maternity ward were recruited during a 4-month study period in 2011. The participants completed self-administered questionnaires on demographic information, a single question on illicit drug use during pregnancy and the DAST-10. Urine samples screened positive by the urine Point-of-Care Test were confirmed by gas chromatography-mass spectrometry. DAST-10 performance was compared with three different gold standards: urinalysis, self-reported drug use, and evidence of drug use by urinalysis or self-report. 1214 Chinese pregnant women participated in the study and 1085 complete DAST-10 forms were collected. Women who had used illicit drugs had significantly different DAST-10 scores than those who had not. The sensitivity of DAST-10 for identify illicit drug use in pregnant women ranged from 79.2% to 33.3% and specificity ranged from 67.7% to 99.7% using cut-off scores from ≥1 to ≥3. The ~80% sensitivity of DAST-10 using a cut-off score of ≥1 should be sufficient for screening of illicit drug use in Chinese pregnant women, but validation tests for drug use are needed.

    A point-of-care immunoassay strip reader, Uniscan™, was applied to detect methamphetamine, opiate, and marijuana in human urine by providing numerical apparent drug concentrations. Calibration curves were determined by a nonlinear regression. The cutoff was verified using spiked controls. Clinical samples were analyzed and compared with enzyme multiplied immunoassay technique (EMIT). The discrepant results were confirmed by gas chromatography-mass spectrometry (GC-MS). The impacts of interference and cross-reactivity were determined for numerous compounds. The coefficients of the calibration curves had a high correlation coefficient. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and total recovery all had high values for spiked controls. For the 19 discrepant results of clinical samples, GC-MS confirmed that Uniscan and EMIT were correct for 11 and eight samples, respectively. For both methamphetamine and opiate, Uniscan had a lower false positive rate, a higher true negative rate, and a higher total recovery rate than EMIT. For marijuana, Uniscan had a higher true positive rate and a lower false negative rate than EMIT. The Uniscan performed excellently when compared to EMIT. It is advantageous for Uniscan to interpret the test result based on digital read-out, rather than subjective visual judgment. PMID:22471608

    Newborns exposed to illicit drugs or alcohol in utero can face physical, social, and emotional obstacles. Outcomes for children with fetal alcohol syndrome disorders are well documented in the literature. Data exist on the effects of maternal illicit drug use. Identifying perinatal substance abuse can increase positive outcomes for newborns and create the opportunity for mothers to access assistance through referrals to community resources.This article provides insight on how hospitals can implement an effective screening tool through patient surveying and testing, nurse education, and collaboration with community agencies in a multidisciplinary advisory committee setting.This discussed method of universal perinatal screening results in increased positive screens and increased referrals for care and support. Emphasis is placed on universal screening and testing methods. Nurses are trained in motivational interview techniques that convey empathy, listening, and objectivity. Community agencies partner with hospital staff through onsite meetings with families that determine the best discharge plan for the newborn. The multidisciplinary advisory committee meets continually to discuss future enhancements. PMID:22123347

    BACKGROUND Oral fluid (OF) is an exciting alternative matrix for monitoring drugs of abuse in workplace, clinical toxicology, criminal justice, and driving under the influence of drugs (DUID) programs. During the last 5 years, scientific and technological advances in OF collection, point-of-collection testing devices, and screening and confirmation methods were achieved. Guidelines were proposed for workplace OF testing by the Substance Abuse and Mental Health Services Administration, DUID testing by the European Union’s Driving under the Influence of Drugs, Alcohol and Medicines (DRUID) program, and standardization of DUID research. Although OF testing is now commonplace in many monitoring programs, the greatest current limitation is the scarcity of controlled drug administration studies available to guide interpretation. CONTENT This review outlines OF testing advantages and limitations, and the progress in OF that has occurred during the last 5 years in collection, screening, confirmation, and interpretation of cannabinoids, opioids, amphetamines, cocaine, and benzodiazepines. We examine controlled drug administration studies, immunoassay and chromatographic methods, collection devices, point-of-collection testing device performance, and recent applications of OF testing. SUMMARY Substance Abuse and Mental Health Services Administration approval of OF testing was delayed because questions about drug OF disposition were not yet resolved, and collection device performance and testing assays required improvement. Here, we document the many advances achieved in the use of OF. Additional research is needed to identify new bio-markers, determine drug detection windows, characterize OF adulteration techniques, and evaluate analyte stability. Nevertheless, there is no doubt that OF offers multiple advantages as an alternative matrix for drug monitoring and has an important role in DUID, treatment, workplace, and criminal justice programs.

    2011-01-01

    The purpose of this system is to simulate an internal short on battery cells by causing deformation (a crushing force) in a cell without penetration. This is performed by activating a hydraulic cylinder on one side of a blast wall with a hydraulic pump located on the other. The operator can control the rate of the crush by monitoring a local pressure gauge connected to the hydraulic cylinder or a load cell digital display located at the hydraulic pump control area. The internal short simulated would be considered a worst-case scenario of a manufacturer fs defect. This is a catastrophic failure of a cell and could be a very destructive event. Fully charged cells are to have an internal short simulated at the center of the length of the cell (away from terminals). The crush can be performed with a .- to 1-in. (.0.6- to 2.5-cm) rod placed crossways to the cell axis, causing deformation of the cell without penetration. The OCV (open-circuit voltage) and temperature of the cells, as well as the pressure and crushing force, are recorded during the operation. Occurrence of an internal short accompanied by any visible physical changes such as venting, fires, or explosions is reported. Typical analytical data examined after the test would be plots of voltage, temperature, and pressure or force versus time. The rate of crushing force can be increased or decreased based on how fast the operator pumps the hydraulic pump. The size of cylinder used to compress the battery cell can be easily changed by adding larger or smaller fittings onto the end of the hydraulic cylinder based on the battery/cell size being tested. The cell is crushed remotely and videotaped, allowing the operator to closely monitor the situation from a safe distance.

    Accurate medical histories for all NHRVs screening to participate in clinical pharmacology trials are vital to ensure volunteers' safety, and integrity of study results. Evidence from previous studies illustrate the potential for NHRVs to misrepresent their histories, especially when monetary incentives are offered, and the need to objectively verify these self-reported histories whenever practical. This study demonstrates that among the sample participants, all of whom self-reported a negative history of drug and alcohol abuse and tobacco smoking, 16% failed urine testing for either alcohol and drugs of abuse (6%), or cotinine (11%). Male sex and increased number of screenings in the preceding 12 months were significantly associated with increased odds for urine screen failure whereas increased enrollments in the same time period and increased study stipend decreased the same odds. These results emphasize the importance of diligently screening NHRVs participating in phase I clinical trails. PMID:18496258

    Introduction Cannabis is Europe's most commonly used illicit drug. Some users do not develop dependence or other problems, whereas others do. Many factors are associated with the occurrence of cannabis-related disorders. This makes it difficult to identify key risk factors and markers to profile at-risk cannabis users using traditional hypothesis-driven approaches. Therefore, the use of a data-mining technique called binary recursive partitioning is demonstrated in this study by creating a classification tree to profile at-risk users. Methods 59 variables on cannabis use and drug market experiences were extracted from an internet-based survey dataset collected in four European countries (Czech Republic, Italy, Netherlands and Sweden), n = 2617. These 59 potential predictors of problematic cannabis use were used to partition individual respondents into subgroups with low and high risk of having a cannabis use disorder, based on their responses on the Cannabis Abuse Screening Test. Both a generic model for the four countries combined and four country-specific models were constructed. Results Of the 59 variables included in the first analysis step, only three variables were required to construct a generic partitioning model to classify high risk cannabis users with 65–73% accuracy. Based on the generic model for the four countries combined, the highest risk for cannabis use disorder is seen in participants reporting a cannabis use on more than 200 days in the last 12 months. In comparison to the generic model, the country-specific models led to modest, non-significant improvements in classification accuracy, with an exception for Italy (p = 0.01). Conclusion Using recursive partitioning, it is feasible to construct classification trees based on only a few variables with acceptable performance to classify cannabis users into groups with low or high risk of meeting criteria for cannabis use disorder. The number of cannabis use days in the last 12 months is the

    2013-01-01

    Alcohol and drug use is a significant public health problem with particular implications for the health and safety of women. Women who abuse these substances are more likely to have untreated depression and anxiety and are at higher risk for intimate partner violence, homelessness, incarceration, infectious disease, and unplanned pregnancy. Substance abuse during pregnancy places both mother and fetus at risk for adverse perinatal outcomes. Data regarding the prevalence of substance abuse in women are conflicting and difficult to interpret. On the clinical level, strong arguments exist against routine urine drug testing and in favor of the use of validated instruments to screen women for drug and alcohol use both in primary women's health care and during pregnancy. A number of sex-specific screening tools are available for clinicians, some of which have also been validated for use during pregnancy. Given the risks associated with untreated substance abuse and dependence in women, the integration of drug and alcohol screening into daily clinical practice is imperative. This article reviews screening tools available to providers in both the prenatal and primary women's health care settings and addresses some of the challenges raised when women screen positive for drug and alcohol abuse.

    Substance use is the most common health risk behavior among adolescents and is one of the greatest threats to their current and future health. Universal screening of adolescents in general medical settings can be instrumental in identifying substance use early, before further problems develop and when BIs are more likely to be effective. Screening in and of itself may have some therapeutic effect. Brief screening tools feasible for use by busy medical offices to quickly and reliably assess adolescent risk for a substance use disorder now are available. A recent study found that a physician-conducted CRAFFT screen interview required an average of 74 seconds to complete, whereas a computer self-administered version took an average of 49 seconds. The CRAFFT and AUDIT tools currently have the most evidence for validity among adolescents, whereas the validity of other widely used tools such as DAST-10, NIDA-modified ASSIST (Alcohol, Smoking and Substance Involvement Screening Test), and ultra-brief screens (AUDIT-C, single-item screens) has yet to be established for adolescents. Studies are needed to identify effective strategies to promote universal adolescent screening and the use of valid screening tools in general medical settings. One statewide (Massachusetts) study found that although most (86%) primary care physicians seeing adolescents reported screening adolescents for substance use annually, only 1 in 3 reported using a validated tool (the CRAFFT). The remaining physicians reporting using informal screening procedures, their own questionnaire, or the CAGE. Computerization of screening and integration into the electronic health record appear to be promising strategies to promote universal screening and standardized use of valid screening tools. Increasing adolescent screening rates necessitates supporting physicians' ability to respond effectively to the screen results. To that end, recent evidence-informed practice guides from the AAP and NIAAA provide a

    In France, workplace testing of drugs of abuse and psychotropic drugs is rarely performed; meanwhile it is a major public health problem. Furthermore, France is the European country that has been associated with the highest increase of the use of drugs of abuse, particularly cannabis. So workplace biological screening of drugs of abuse and of psychotropic drugs exposure is of major concern. New analytical techniques have been developed during the last years. The authors will consider analytical screening of drugs of abuse and particularly the comparison of analytical techniques applied to urine and saliva. The advantages and the disadvantages of these two matrices will be considered. Urinary and blood quantification will be reviewed, but also the interest of hair testing to explore chronic exposure. The research of psychotropic drugs in biological fluids is also a part of this paper. New analytical trends are promising and complete analysis of these substances will be soon routinely possible in blood using a single spot test. PMID:22655580

    PubMed Central

    2012-01-01

    Background To identify facilitators of, and barriers to, screening for child abuse in emergency departments (ED) through interviews with ED staff, members of the hospital Board, and related experts. Methods This qualitative study is based on semi-structured interviews with 27 professionals from seven Dutch hospitals (i.e. seven pediatricians, two surgeons, six ED nurses, six ED managers and six hospital Board members). The resulting list of facilitators/barriers was subsequently discussed with five experts in child abuse and one implementation expert. The results are ordered using the Child Abuse Framework of the Dutch Health Care Inspectorate that legally requires screening for child abuse. Results Lack of knowledge of child abuse, communication with parents in the case of suspected abuse, and lack of time for development of policy and cases are barriers for ED staff to screen for child abuse. For Board members, lack of means and time, and a high turnover of ED staff are impediments to improving their child abuse policy. Screening can be promoted by training ED staff to better recognize child abuse, improving communication skills, appointing an attendant specifically for child abuse, explicit support of the screening policy by management, and by national implementation of an approved protocol and validated screening instrument. Conclusions ED staff are motivated to work according to the Dutch Health Care Inspectorate requirements but experiences many barriers, particularly communication with parents of children suspected of being abused. Introduction of a national child abuse protocol can improve screening on child abuse at EDs. PMID:23092228

    Psychiatric disorders, particularly depression and alcohol abuse, represent a large burden of illness to the society. Many individuals with these disorders receive all of their care from health care providers who are not mental health specialists. There is evidence that non-psychiatric physicians frequently do not recognize these disorders in their patients. Screening questionnaires have been introduced to improve detection of these patients. Several studies have found that these screening questionnaires can increase detection rates, but no important impact on patient outcomes has been demonstrated. This review article outlines several reasons why it has been difficult to discern improvement in patient outcomes: inadequate study design, insufficient physician education, interdependence of psychiatric and medical conditions, and vague treatment guidelines. Practical use of the current psychiatric screening questionnaires and key areas for further investigation are considered. PMID:2231063

    The psychometric properties of the Drug Use Disorders Identification Test (DUDIT), an 11-item self-report questionnaire developed to screen individuals for drug problems, are evaluated. The measure, developed in Sweden and evaluated there with individuals with severe drug problems, has not been evaluated with less severe substance abusers or with clinical populations in the United States. Participants included 35 drug abusers in an outpatient substance abuse treatment program, 79 drug abusers in a residential substance abuse treatment program, and 39 alcohol abusers from both treatment settings who did not report a drug abuse problem. The DUDIT was found to be a psychometrically sound drug abuse screening measure with high convergent validity (r=.85) when compared with the Drug Abuse Screening Test (DAST-10), and to have a Cronbach's alpha of .94. In addition, a single component accounted for 64.91% of total variance, and the DUDIT had sensitivity and specificity scores of .90 and .85, respectively, when using the optimal cut-off score of 8. Additionally, the DUDIT showed good discriminant validity as it significantly differentiated drug from alcohol abusers. These findings support the DUDIT as a reliable and valid drug abuse screening instrument that measures a unidimensional construct. Further research is warranted with additional clinical populations.

    Forrest, A R

    1997-01-01

    OBJECTIVE: To review the ethical and legal implications of the involvement of medical practitioners in workplace screening for drug misuse. CONCLUSIONS: Workplace screening for drugs of abuse raises many ethical issues. If screening is considered as being part of medical practice with the involvement of occupational health physicians, as suggested by the Faculty of Occupational Medicine, then the ethical requirements of a normal medical consultation are fully applicable. The employee's full and informed consent to the process must be obtained and the employee should have an unfettered right of access to all the relevant records and to the urine sample he/she has provided in the event that he/she wishes to challenge the opinion expressed by the physician. If the process is not part of medical practice then employees should have the same rights as they would have if required to provide intimate body samples in the course of a criminal investigation, given the potentially serious consequences of an erroneous positive finding for their livelihood.

    The purpose of the study was to evaluate the relative merits of two screening tests used for visual acuity assessment of preschool children. The tests that were compared were the Good-Lite Company versions of the E-Test and of the STYCAR (Screening Test for Young Children and Retardates). The former is the most popular method for evaluating central acuity in young children in this nation; the STYCAR is a relatively new letter-matching-test developed in England, where it is widely employed. The E-Test poses left-right orientation problems which are eliminated by the symmetrical letters H, T, O and V utilized in the Letter-Matching-Test. Both visual acuity tests were administered on two separate occasions by personnel from the Prevention of Blindness Society of Metropolitan Washington to 633 preschool children in Washington, D.C. By random selection, 150 of the children received the E-Test at both sessions, 162 children received the Letter-Matching-Test at both sessions, 160 chilt athe the second session, and 161 children received the Letter-Matching-Test at the first session and the E-Test at the second session. The author medically examined the eyes of 408 of the 633 children without knowledge of which test had been initially administered. Statistical analysis of the data obtained from the study indicated that the Letter-Matching-Test was significantly better in terms of testability rates, group and individual instruction time, and performance time. The E-Test was more reliable in terms of test-retest acuity scores and was also more valid in terms of agreement between pass-fail results obtained at the first screening session and two levels of pass-fail refraction criteria.

    A program for evaluating packaging components that may be used in transporting mixed-waste forms has been developed and the first phase has been completed. This effort involved the screening of ten plastic materials in four simulant mixed-waste types. These plastics were butadiene-acrylonitrile copolymer rubber, cross-linked polyethylene (XLPE), epichlorohydrin rubber, ethylene-propylene rubber (EPDM), fluorocarbon (Viton or Kel-F), polytetrafluoroethylene, high-density polyethylene (HDPE), isobutylene-isoprene copolymer rubber (butyl), polypropylene, and styrene-butadiene rubber (SBR). The selected simulant mixed wastes were (1) an aqueous alkaline mixture of sodium nitrate and sodium nitrite; (2) a chlorinated hydrocarbon mixture; (3) a simulant liquid scintillation fluid; and (4) a mixture of ketones. The testing protocol involved exposing the respective materials to 286,000 rads of gamma radiation followed by 14-day exposures to the waste types at 60{degrees}C. The seal materials were tested using vapor transport rate (VTR) measurements while the liner materials were tested using specific gravity as a metric. For these tests, a screening criterion of 0.9 g/hr/m{sup 2} for VTR and a specific gravity change of 10% was used. Based on this work, it was concluded that while all seal materials passed exposure to the aqueous simulant mixed waste, EPDM and SBR had the lowest VTRs. In the chlorinated hydrocarbon simulant mixed waste, only Viton passed the screening tests. In both the simulant scintillation fluid mixed waste and the ketone mixture simulant mixed waste, none of the seal materials met the screening criteria. For specific gravity testing of liner materials, the data showed that while all materials with the exception of polypropylene passed the screening criteria, Kel-F, HDPE, and XLPE offered the greatest resistance to the combination of radiation and chemicals.

  17. Testing the sexually abused-sexual abuser hypothesis: A prospective longitudinal birth cohort study.

    PubMed

    Leach, Chelsea; Stewart, Anna; Smallbone, Stephen

    2016-01-01

    The sexually abused-sexual abuser hypothesis posits that persons, especially males, who are sexually abused as children are at particular risk of sexually abusing others later in life. We tested this hypothesis by prospectively examining associations between maltreatment and offending in a birth cohort of 38,282 males with a maltreatment history and/or at least one finalized offense. We examined these associations within the context of the wider birth population. Proportionally few boys were the subject of official notifications for sexual abuse (14.8% of maltreated boys, and 1.4% of the birth population); proportionally very few of these sexually abused boys (3%) went on to become sexual offenders; and, contrary to findings typically reported in retrospective clinical studies, proportionally few sexual offenders (4%) had a confirmed history of sexual abuse. Poly-victimization (exposure to multiple types of maltreatment) was significantly associated with sexual offending, violent offending, and general (nonsexual, nonviolent) offending. We found no specific association between sexual abuse and sexual offending, and nor did we find any association between sexual abuse and sexual offending specifically within the poly-victimized group. The total number of sexual abuse notifications did make a small unique contribution to the variance in sexual offending compared to other offending. Implications concerning maltreated boys and male sexual offenders are discussed. PMID:26615777

  18. Hyperaldosteronism: Screening and Diagnostic Tests.

    Primary aldosteronism (PA) is the most common secondary cause of hypertension, accounting for 10 % of hypertensives and 20 % of those with drug-resistant hypertension. Aldosterone excess is associated with the development of adverse cardiovascular, renal and metabolic effects that are partly independent of its effect on blood pressure. Guidelines recommended wider screening for PA in an effort to maximize detection of patients who may benefit from optimal, specific management. All patient groups with increased prevalence of PA, including hypertensive patients with type 2 diabetes mellitus and those with obstructive sleep apnea, should be carefully screened for PA. Screening with aldosterone-to-renin ratio (ARR) is the most practical and informative initial test. Subsequent confirmatory tests are: (1) oral salt loading; (2) saline infusion; (3) captopril challenge and (4) fludrocortisone suppression test. Confirmation of PA can avoid that patients with a false positive ARR would inappropriately undergo costly and harmful lateralization procedures. If confirmatory testing is positive, further investigations are directed toward determining the subtype of PA, as the treatment differs for each subtype. PMID:26971505

    The purpose of this work was to develop and evaluate a fast, robust and specific UPLC-MS/MS screening platform for the determination and quantification of a variety of commonly used drugs of abuse in urine, i.e. a high-throughput quantitative analysis. Substances in the drug classes opioids, central nervous system stimulants and benzodiazepines and related agents were included in addition to cannabis and pregabalin, a total of 35 different analytes. Based on the concentrations and the physico-chemical properties of the substances, three UPLC-MS/MS methods were developed in parallel. Prior to analysis, sample preparation consisted of two different simple dilutions with 60 and 100 μL urine, respectively, using a Tecan Freedom Evo pipetting robot platform. A Waters Xevo TQ-S tandem quadrupole mass spectrometer coupled to a Waters I-class UPLC was used for quantitative analysis of one quantitative and one qualifying MRM transition for each analyte, except for tramadol for which the metabolite O-desmethyl-tramadol was included in the MRM method to confirm tramadol identity. Deuterated analogs were included as internal standards. The between-assay relative standard deviations varied from 2% to 11% and the limits of quantification were in the range 1-200 ng/mL for the various analytes. After development and initial testing, the method has been successfully implemented and routinely used at our hospital for quantitative screening of drugs of abuse in more than 35,000 urinary samples.

    2016-07-15

    Primary prevention programs of pediatric abusive head trauma (PAHT) exist and early screening is proposed, but negative effects of mislabeling parents as abusers, an important issue, are not well documented. The aim of our study was to simulate the possible impact of programs for the primary prevention and screening of PAHT. We developed Markov models that simulate the life histories of PAHT with no intervention, with primary prevention program only, with screening program, and with both programs in a hypothetical cohort of 800,000 newborns in a high-income country. Screening program would be addressed to all families until children are 2 years old, during repeated consultations. Potential side effects for parents being mislabeled as abusers were supposed to increase the probability of PAHT and decrease participation in screening. Time horizon was 2 years with cycles of 15 days. Outcomes were number of deaths and abused children avoided. Uncertainty was specified with probability distributions. After 2 years, the median number of deaths avoided through primary prevention would vary from 6 (95% confidence interval [CI] 2-11) to 28 (95% CI 6-51) per 100,000 newborns. Screening could prevent up to 6 (95% CI 0-29) or cause up to 66 (95% CI 0-361) deaths per 100,000 children born alive. The impact of both programs was uncertain. Our model confirmed the potential benefits of primary prevention and documented the uncertainty associated with screening of PAHT. PMID:26566679

    A long-standing belief in the literature on sex offenders is that sexually victimized youths are at increased risk of becoming sex offenders themselves. The present study tested the link between past sexual abuse, either with or without contact, and sexually offending behavior in a representative sample of male and female adolescents while controlling for other types of abuse, mental health problems, substance use, and non-sexual violent behaviors. Self-reported data were collected from a nationally representative sample of 6,628 students attending 9th grade public school in Switzerland (3,434 males, 3,194 females, mean age = 15.50 years, SD = 0.66 years). Exposure to contact and non-contact types of sexual abuse was assessed using the Child Sexual Abuse Questionnaire and sexually offending behavior by the presence of any of three behaviors indicating sexual coercion. Two-hundred-forty-five males (7.1 %) and 40 females (1.2 %) reported having sexually coerced another person. After controlling for non-sexual abuse, low parent education, urban versus rural living, mental health problems, substance use, and non-sexual violent behavior, male adolescents who were victims of contact sexual abuse and non-contact sexual abuse were significantly more likely to report coercive sexual behaviors. Females who experienced contact or non-contact sexual abuse were also found at increased risk of committing sexual coercion after controlling for covariates. The present findings demonstrate a strong relationship between past sexual abuse, with and without physical contact, and sexual-offending behavior in male and female adolescents. Reducing exposure to non-contact sexual abuse (like Internet-based sexual exploitation) should become a new area of sexual violence prevention in youths. PMID:25981223

    1994-01-01

    One hundred and twenty inmates enrolled in a comprehensive residential drug treatment program were administered the Drug Lifestyle Screening Interview (DLSI), a structured interview designed to assess the four behavioral characteristics of lifestyle drug abuse: i.e., irresponsibility/pseudoresponsibility, stress-coping imbalance, interpersonal triviality, and social rule breaking/bending. Subjects reporting a high volume of prior substance misuse (moderate to severe abuse of at least three different substances or severe abuse of one substance other than marijuana) recorded significantly higher scores on each of the four behavioral dimensions of lifestyle drug abuse than subjects possessing a lower volume of prior substance misuse. Furthermore, a score of 10 or higher on the DLSI cumulative index classified 76.7% of the high volume users but only 37.2% of the low volume users as lifestyle drug abusers for an overall hit rate of 71.7%.

    Background Despite the importance of identifying co-occurring psychiatric disorders in substance abuse treatment programs, there are few appropriate and validated instruments available to substance abuse treatment staff to conduct brief screen for these conditions. This paper describes the development, implementation and validation of a brief screening instrument for mental health diagnoses and trauma among a diverse sample of Black, Hispanic and White women in substance abuse treatment. With input from clinicians and consumers, we adapted longer existing validated instruments into a 14 question screen covering demographics, mental health symptoms and physical and sexual violence exposure. All women entering treatment (methadone, residential and out-patient) at five treatment sites were screened at intake (N = 374). Results Eighty nine percent reported a history of interpersonal violence, and 70% reported a history of sexual assault. Eighty-eight percent reported mental health symptoms in the last 30 days. The screening questions administered to 88 female clients were validated against in-depth psychiatric diagnostic assessments by trained mental health clinicians. We estimated measures of predictive validity, including sensitivity, specificity and predictive values positive and negative. Screening items were examined multiple ways to assess utility. The screen is a useful and valid proxy for PTSD but not for other mental illness. Conclusion Substance abuse treatment programs should incorporate violence exposure questions into clinical use as a matter of policy. More work is needed to develop brief screening tools measures for front-line treatment staff to accurately assess other mental health needs of women entering substance abuse treatment PMID:16959041

    The series of tests described in this report are intended to simulate actual use and abuse conditions and internally initiated failures that may be experienced in electrochemical storage systems (ECSS). These tests were derived from Failure Mode and Effect Analysis, user input, and historical abuse testing. The tests are to provide a common framework for various ECSS technologies. The primary purpose of testing is to gather response information to external/internal inputs. Some tests and/or measurements may not be required for some ECSS technologies and designs if it is demonstrated that a test is not applicable, and the measurements yield no useful information.

    Stracci, Fabrizio; Zorzi, Manuel; Grazzini, Grazia

    2014-01-01

    Screening has a central role in colorectal cancer (CRC) control. Different screening tests are effective in reducing CRC-specific mortality. Influence on cancer incidence depends on test sensitivity for pre-malignant lesions, ranging from almost no influence for guaiac-based fecal occult blood testing (gFOBT) to an estimated reduction of 66–90% for colonoscopy. Screening tests detect lesions indirectly in the stool [gFOBT, fecal immunochemical testing (FIT), and fecal DNA] or directly by colonic inspection [flexible sigmoidoscopy, colonoscopy, CT colonography (CTC), and capsule endoscopy]. CRC screening is cost-effective compared to no screening but no screening strategy is clearly better than the others. Stool tests are the most widely used in worldwide screening interventions. FIT will soon replace gFOBT. The use of colonoscopy as a screening test is increasing and this strategy has superseded all alternatives in the US and Germany. Despite its undisputed importance, CRC screening is under-used and participation rarely reaches 70% of target population. Strategies to increase participation include ensuring recommendation by physicians, introducing organized screening and developing new, more acceptable tests. Available evidence for DNA fecal testing, CTC, and capsule endoscopy is reviewed. PMID:25386553

    Kindler, H

    2010-10-01

    Selective primary prevention programs for child abuse and neglect depend on risk screening instruments that have the goal of systematically identifying families who can profit most from early help. Based on a systematic review of longitudinal studies, a set of established risk factors for early child abuse and neglect is presented. Nearly half of the items included in screening instruments can be seen as validated. Available studies indicate a high sensitivity of risk screening instruments. Positive predictive values, however, are low. Overall, the use of risk screening instruments in the area of primary prevention for families at risk represents a feasible method, as long as stigmatizing effects can be avoided and participating families also benefit beyond preventing endangerment.

    Background. Perioperative management of cocaine-abusing patients scheduled for elective surgery varies widely based on individual anecdotes and personal experience. Methods. Chiefs of the anesthesia departments in the Veterans Affairs (VA) health system were surveyed to estimate how often they encounter surgical patients with cocaine use. Respondents were asked about their screening criteria, timing of screening, action resulting from positive screening, and if they have a formal policy for management of these patients. Interest in the development of VA guidelines for the perioperative management of patients with a history of cocaine use was also queried. Results. 172 VA anesthesia departments' chiefs were surveyed. Response rate was 62%. Over half of the facilities see cocaine-abusing patients at least once a week (52%). Two thirds of respondents canceled or delayed patients with a positive screen regardless of clinical symptoms. Only eleven facilities (10.6%) have a formal policy. The majority of facilities (80%) thought that having formal guidelines for perioperative management of cocaine-abusing patients would be helpful to some extent. Results. 172 VA anesthesia departments' chiefs were surveyed. Response rate was 62%. Over half of the facilities see cocaine-abusing patients at least once a week (52%). Two thirds of respondents canceled or delayed patients with a positive screen regardless of clinical symptoms. Only eleven facilities (10.6%) have a formal policy. The majority of facilities (80%) thought that having formal guidelines for perioperative management of cocaine-abusing patients would be helpful to some extent. Conclusions. There is a general consensus that formal guidelines would be helpful. Further studies are needed to help formulate evidence-based guidelines for managing patients screening positive for cocaine prior to elective surgery. PMID:24069030

  15. The effects of adulterants and selected ingested compounds on drugs-of-abuse testing in urine.

    Household chemicals such as bleach, table salt, laundry detergent, toilet bowl cleaner, vinegar, lemon juice, and eyedrops are used for adulterating urine specimens. Most of these adulterants except eyedrops can be detected by routine specimen integrity tests (creatinine, pH, temperature, and specific gravity); however, certain adulterants such as Klear, Whizzies, Urine Luck, and Stealth cannot. These adulterants can successfully mask drug testing if the concentrations of certain abused drugs are moderate. Several spot tests have been described to detect the presence of such adulterants in urine. Urine dipsticks are commercially available for detecting the presence of such adulterants, along with performance of tests for creatinine, pH, and specific gravity. Certain hair shampoo and saliva-cleaning mouthwashes are available to escape detection in hair or saliva samples, but the effectiveness of such products in masking drugs-of-abuse testing has not been demonstrated. Ingestion of poppy seed cake may result in positive screening test results for opiates, and hemp oil exposure can cause positive results for marijuana. These would be identified as true-positive results in drugs-of-abuse testing even though they do not represent the actual drug of abuse. PMID:17709324

    Background A number of practice guidelines and recommendations call for the assessment of childhood abuse history among adult medical patients. The cultural sensitivity of screening questions, however, has not been examined. Objective To assess whether questions that inquire about childhood abuse history function differently for black and white patients. Design Cross-sectional telephone surveys in 1997 and 2003. Subjects Randomly sampled adults from Memphis, Tenn (1997, N = 832; 2003, N = 967). Measurements Physical, emotional, and sexual abuse scales of the Childhood Trauma Questionnaire–Short Form (CTQ-SF). Standardized mean difference technique for differential item functioning to assess for possible bias in CTQ-SF items. Results Controlling for total physical abuse scale scores, black respondents were significantly (P < .01) more likely than white respondents to report that they had been punished with a hard object during their childhood, but less likely to report having being hit so hard that it left marks, have been hit so hard that someone noticed, or to believe they had been physically abused. Conclusions Inquiries that do not explicitly differentiate physical punishment from physical abuse may not be useful for black respondents because they tend to identify black respondents who report fewer clearly abusive experiences than comparable white respondents. Although untested in this study, one possible explanation is that physical discipline may be used more frequently and may play a different role among black families than among white families. These results underline the importance of attending to cultural factors in clinical history taking about childhood abuse histories. PMID:17356970

    The choice of screening or invasive procedure in twin pregnancies is a personal choice of whether the patient wishes to take a small risk of having a baby with a serious disorder versus a small risk of having a complication because she wishes to avoid that. How to interpret such risks has profound effects on the perceived value of techniques, either leading to a decision to screening or going directly to chorionic villus sampling. There are profound issues surrounding the data and the interpretation of the data. No single short review can exhaustively examine all of the issues. PMID:27235913

    Hair testing is a useful tool to investigate the prevalence of unsuspected chronic exposure to drugs of abuse in pediatric populations and it has been applied to three different cohorts of children from Barcelona, Spain along fifteen years to evaluate eventual changes in this exposure. Children were recruited from three independent studies performed at Hospital del Mar (Barcelona, Spain) and approved by the local Ethics Committee. Hair samples were collected from the first 187 children cohort (around 4 years of age) in 1998, from the second 90 children cohort (1.5–5 years of age) in 2008 and from the third 114 children cohort (5–14 years of age) in 2013. Hair samples were analysed for the presence of opiates, cocaine, amphetamines, and cannabis by validated methodologies using gas or liquid chromatography-mass spectrometry. Familiar sociodemographics and eventual consumption of drugs of abuse by parents, and caregivers were recorded. Hair samples from 24.6% children in 1998 were positive for any drug of abuse (23.0% cocaine), 25.5% in 2008 (23.3% cocaine), and 28.1% in 2013 (20.1% cocaine and 11.4% cannabis). In none of the cohorts, parental sociodemographics were associated with children exposure to drugs of abuse. The results of the three study cohorts demonstrated a significant prevalence of unsuspected pediatric exposure to drugs of abuse which mainly involved cocaine maintained along fifteen years in Barcelona, Spain. We recommend to be aware about unsuspected passive exposure to drugs of abuse in general population and to use general or selected hair screening to disclose exposure to drugs of abuse in children from risky environments to provide the basis for specific social and health interventions.

    Despite being an emergent major public health problem, little research has been done on domestic violence from the perspectives of early detection and prevention. Thus, this cross-sectional study was conducted to identify domestic violence among female adult patients attending health centers at the primary care level and to determine the relationship between social correlates of adult patients and domestic violence screening and subsequent help/health-seeking behavior if abused. Face-to-face interviews were conducted with 710 female adult patients from 8 health centers in Selangor who matched the inclusion criteria and consented to participate in the study, using a structured questionnaire that included adaptation of a validated 8-item Women Abuse Screening Tool (WAST). Statistical tests showed significant differences in ethnicity, income, and education between those screened positive and those screened negative for domestic violence. Of the participants, 92.4% reported that during consultations, doctors had never asked them whether they were abused by their husband/partner. Yet, 67.3% said they would voluntarily tell the doctor if they were abused by their husband/partner. The findings indicate that primary care has an important role in identifying domestic violence by applying the WAST screening tool, or an appropriate adaptation, with women patients during routine visits to the various health centers. Such assessment for abuse could be secondary prevention for the abused women, but more important, it will serve as primary prevention for nonabused women. This approach not only will complement the existing 1-stop crisis center policy by the Ministry of Health that copes with crisis intervention but also will spearhead efforts toward prevention of domestic violence in Malaysia.

    Stauffer, Stephanie L; Wood, Stephanie M; Krasowski, Matthew D

    2015-07-01

    Detection of drugs in a child may be the first objective finding that can be reported in cases of suspected child abuse. Hair and urine toxicology testing, when performed as part of the initial clinical evaluation for suspected child abuse or maltreatment, may serve to facilitate the identification of at-risk children. Furthermore, significant environmental exposure to a drug (considered by law to constitute child abuse in some states) may be identified by toxicology testing of unwashed hair specimens. In order to determine the clinical utility of hair and urine toxicology testing in this population we performed a retrospective chart review on all children for whom hair toxicology testing was ordered at our academic medical center between January 2004 and April 2014. The medical records of 616 children aged 0-17.5 years were reviewed for injury history, previous medication and illicit drug use by caregiver(s), urine drug screen result (if performed), hair toxicology result, medication list, and outcome of any child abuse evaluation. Hair toxicology testing was positive for at least one compound in 106 cases (17.2%), with unexplained drugs in 82 cases (13.3%). Of these, there were 48 cases in which multiple compounds (including combination of parent drugs and/or metabolites within the same drug class) were identified in the sample of one patient. The compounds most frequently identified in the hair of our study population included cocaine, benzoylecgonine, native (unmetabolized) tetrahydrocannabinol, and methamphetamine. There were 68 instances in which a parent drug was identified in the hair without any of its potential metabolites, suggesting environmental exposure. Among the 82 cases in which hair toxicology testing was positive for unexplained drugs, a change in clinical outcome was noted in 71 cases (86.5%). Urine drug screens (UDS) were performed in 457 of the 616 reviewed cases. Of these, over 95% of positive UDS results could be explained by iatrogenic drug

    Objective The childhood sexual abuse (CSA) survivor population is substantial and survivors have been identified as part of the population who were under-screened or never-screened for breast, cervical and colon cancer. Our objective was to learn CSA survivor perspectives on, and experiences with, breast, cervical and colon cancer screening with the intention of generating recommendations to help healthcare providers improve cancer screening participation. Design A pragmatic constructivist qualitative study involving individual, semistructured, in-depth interviews was conducted in January 2014. Thematic analysis was used to describe CSA survivor perspectives on cancer screening and identify potential facilitators for screening. Participants A diverse purposive sample of adult female CSA survivors was recruited. The inclusion criteria were: being a CSA survivor, being in a stable living situation, where stable meant able to meet one's financial needs independently, able to maintain supportive relationships, having participated in therapy to recover from past abuse, and living in a safe environment. 12 survivors were interviewed whose ages ranged from the early 40s to mid-70s. Descriptive saturation was reached after 10 interviews. Setting Interviews were conducted over the phone or Internet. CSA survivors were primarily from urban and rural Ontario, but some resided elsewhere in Canada and the USA. Results The core concept that emerged was that compassionate care at every level of the healthcare experience could improve cancer screening participation. Main themes included: desire for holistic care; unique needs of patients with dissociative identity disorder; the patient-healthcare provider relationship; appointment interactions; the cancer screening environment; and provider assumptions about patients. Conclusions Compassionate care can be delivered by: building a relationship; practising respect; focusing attention on the patient; not rushing the appointment

  12. Interpretation of Oral Fluid Tests for Drugs of Abuse

    CONE, EDWARD J.; HUESTIS, MARILYN A.

    2009-01-01

    Oral fluid testing for drugs of abuse offers significant advantages over urine as a test matrix. Collection can be performed under direct observation with reduced risk of adulteration and substitution. Drugs generally appear in oral fluid by passive diffusion from blood, but also may be deposited in the oral cavity during oral, smoked, and intranasal administration. Drug metabolites also can be detected in oral fluid. Unlike urine testing, there may be a close correspondence between drug and metabolite concentrations in oral fluid and in blood. Interpretation of oral fluid results for drugs of abuse should be an iterative process whereby one considers the test results in the context of program requirements and a broad scientific knowledge of the many factors involved in determining test outcome. This review delineates many of the chemical and metabolic processes involved in the disposition of drugs and metabolites in oral fluid that are important to the appropriate interpretation of oral fluid tests. Chemical, metabolic, kinetic, and analytic parameters are summarized for selected drugs of abuse, and general guidelines are offered for understanding the significance of oral fluid tests.

    Purpose: Currently, there is a claim for earlier interventions for families in order to prevent child maltreatment. Here, a screening instrument to assess risk indicators for child abuse and neglect already in the context of maternity clinics is introduced. The present study is the first report on the psychometric properties of this instrument, the "short questionnaire for risk indices around birth" (RIAB). Material and Methods: Data were collected in the context of three different studies conducted at Ulm University Hospital. To examine interrater reliability eight case vignettes were rated by n = 90 study participants (50 students and 40 experts working at a maternity clinic). Criterion validity was examined in two studies applying the German version of the child abuse potential inventory CAPI (n = 96 families at risk and n = 160 additional families). Results: Both laymen and experts were able to understand and use the screening instrument correctly, leading to a high agreement with the sample solutions given. A high concordance was found between parents' and experts' ratings: In case of no reported risk factors applying the screening instrument RIAB, parents themselves reported significantly less stressors and burdens, compared to those parents with an indication for a thorough examination as pointed out in the RIAB. Conclusion: In the context of maternity clinics the RIAB is a useful, broadly applicable instrument, screening for existing risk factors at the earliest and thus allowing for the initiation of specific interventions when needed.

    Treatment of adolescent substance abusers is difficult. Treatment programs at multiple levels, from inpatient facilities to outpatient support groups, usually are available. Some of the most encouraging results have come from programs that involve family therapy in addition to individual treatment. 22 Knowing what resources are available, as well as the referral processes based on a particular patient's healthcare plans, facilitates access and makes dealing with these issues in a busy outpatient setting much easier. Frequent follow-up with an adolescent after a treatment program has been initiated to monitor for compliance and relapse can ensure a better drug-free outcome. Knowing the extent of the adolescent drug abuse problem should encourage providers to incorporate some type of screening into their routine care of adolescents. None of these methods is 100% sensitive, and incorporating each component into the process where appropriate likely is the best approach. Knowing risk and protective factors for drug use is helpful for both recognition of candidates for screening and counseling of parents regarding drug use prevention. PMID:16419733

    An immunoassay was established which enables a reliable quantification of serological drug samples. The assay is based on a competitive ELISA. In total nine drugs (amphetamine, methamphetamine, 3,4-methylenedioxy-methamphetamine (MDMA), tetrahydrocannabinol (THC), phencyclidine (PCP), methadone, morphine, cocaine and benzoylecgonine) were tested. All reagents had to pass through a stringent validation process. Within the established test for three out of the nine drugs no cross-reactivity with any tested compounds, e.g. serum, other antibodies or chemically related molecules was detectable for the tested antibodies. Furthermore, a sensitive and selective detection was possible, even in the presence of up to 9 drugs or of various anti-drug antibodies. After exclusion of cross-reactivities antibodies against three drugs (methadone, MDMA, benzoylecgonine) were validated, which allowed a specific and sensitive quantification. For the competitive measurements CVs in the range of 2-17% could be reached with LLOQs of 10ng/mL and LODs of 150ng/mL for methadone, 250ng/mL for MDMA and 400ng/mL for benzoylecgonine. Anonymized serum samples (n=10) provided by the office of criminal investigation Berlin were analyzed for verification purposes. Evaluation of these data showed a correlation (CV) of ≈0.9 with standard GC-MS methods. A miniaturization on microarray was possible by using the anti-MDMA antibody for the detection of MDMA in serum. The microarray increased the through-put drastically and enabled the simultaneous quantification of various drugs. PMID:27343723

    Little is known about the association between personality disorders and neuropsychological test performance in chronic cocaine users. The aims of the present study were to (1) pinpoint the specific neuropsychological characteristics of chronic cocaine abusers, (2) analyze their personality profile, and (3) explore the association between personality traits and neuropsychological test performance. A sample of 42 drug-abusers (mean age = 34.15; SD = 6.73; mean educational level = 11.44; SD = 2.01) was selected from a state rehabilitation facility and was compared to a control group (mean age = 34.53; SD = 9.01; mean educational level = 12.29; SD = 1.31). The following information was collected for each subject: (1) A clinical history adapted from Horton (1996). (2) The Personality Assessment Inventory (PAI) (Morey, 1991). (3) A neuropsychological test battery including: Arithmetic and Digits subtests from the WAIS-R, California Verbal Learning Test, Trial Making Test, Verbal Fluency tests, Rey-Osterrieth Complex Figure, Wisconsin Card Sorting Test, Benton Visual Retention Test, Stroop Neurological Screening Test and Hooper Visual Organization. Thirty-seven of the drug-dependent subjects obtained an abnormal score in at least one PAI scale. The personality profile of the drug-dependent subjects found via the PAI pointed to a Borderline/Antisocial personality, frequently associated with mania features. In six of the drug-abusers, a normal personality profile was observed. Neuropsychological test performance scores were within the low average or borderline range. The most abnormal scores were observed in attention, memory, and executive functioning tests. The results did not show any robust association between personality profile and neuropsychological test performance. PMID:11697211

    In studies of screening accuracy, we may commonly encounter the data in which a confirmatory procedure is administered to only those subjects with screen positives for ethical concerns. We focus our discussion on simultaneously testing equality of sensitivity and specificity between two binary screening tests when only subjects with screen positives receive the confirmatory procedure. We develop four asymptotic test procedures and one exact test procedure. We derive sample size calculation formula for a desired power of detecting a difference at a given nominal [Formula: see text]-level. We employ Monte Carlo simulation to evaluate the performance of these test procedures and the accuracy of the sample size calculation formula developed here in a variety of situations. Finally, we use the data obtained from a study of the prostate-specific-antigen test and digital rectal examination test on 949 Black men to illustrate the practical use of these test procedures and the sample size calculation formula.

    It is estimated that 8% to 12% of American youths have experienced at least one sexual assault in their lifetime, making childhood sexual abuse (CSA) an important public health problem that is likely to be encountered by primary care providers. Use of screening tools and understanding the principles behind targeted clinical evaluation can aid in identification of CSA victims despite highly variable presentation. The primary care provider must be aware of potential signs and symptoms as well as differential diagnoses in order to identify children who may benefit from further mental health evaluation and intervention.

    Osteoporosis is a major public health concern. Substance abuse and psychosis may be risk factors, however frequency of screening and disease risk in women with psychotic disorders and substance use disorder (SUD) remains unknown. Methods This study examined rates (FY 2005) of osteoporosis screening and disease risk in Medicaid enrolled women aged 50 to 64 (N=18,953). Four diagnostic groups were characterized: 1) Psychosis; 2) SUD; 3) Major mood disorder and 4) Controls. The interaction of psychosis and SUD on screening and disease prevalence of osteoporosis was tested. Results The prevalence of osteoporosis across the entire population was 6.7%. Four percent of those without an osteoporosis diagnosis received osteoporosis screening with no notable differences between psychosis and controls. Those with SUD, however, had a significant reduction in screening compared to controls (OR=0.61, 95% CI 0.40–0.91, p=0.016). Women with a major mood disorder were more likely to have osteoporosis in their administrative record (OR=1.32, 95% CI=1.03–1.70, p=0.028) compared to controls. Those who were dually diagnosed (SUD and psychosis) in the oldest ages (55–64 years) had a markedly higher prevalence of osteoporosis compared to controls (OR=6.4 CI 1.51–27.6, p=0.012), whereas this interaction (SUD and psychosis) was not significant in the entire population over age 49. Conclusions Osteoporosis screening in the Medicaid population is significantly lower for women with SUD, after adjusting for age, race and Medicaid enrollment category. The prevalence of osteoporosis appears markedly elevated in those with major mood disorders and those over age 55 dually diagnosed with schizophrenia and SUD. PMID:20533029

    Human papillomavirus (HPV) testing is more reliable and sensitive but less specific than Papanicolaou (Pap) testing/cervical cytology for the detection of cervical precancer and cancer. HPV-negative women are at lower risk of cervical cancer than Pap-negative women. In high-resource settings, HPV testing can be used to make cervical cancer prevention programs more efficient by focusing clinical attention on women who have HPV. In lower-resource settings, where Pap testing has not been sustained or widespread, new, lower-cost HPV tests may make cervical cancer screening feasible. PMID:23732037

    A comprehensive drug screening procedure for detecting drugs in the blood samples of car drivers suspected of driving under the influence of drugs, is presented. Amphetamines, cannabinoids, opioids, cocaine and benzodiazepines were screened by an immunological EMIT ETS system after acetone precipitation. Gas chromatographic methods were used to screen and quantitate basic, neutral and acidic drugs. The free amino groups of basic drugs were derivatized with heptafluorobutyric anhydride. Analysis was performed by a dual channel gas chromatograph combined with a nitrogen phosphorus and an electron capture detector. Phenyltrimethylammonium hydroxide was used as a methylathing agent for acidic substances before analysis with a gas chromatograph connected to a nitrogen phosphorus detector. A gas chromatograph/mass spectrometry was used as a common confirmation method. Tetrahydrocannabinol was quantitated after bis(trimethylsilyl)trifluoroacetamide derivatization, opiates after pentafluoropropionic anhydride derivatization and benzoylecgonine after pentafluoropropionic anhydride and pentafluoropropanol derivatization. Excluding benzodiazepines, which were confirmed with a gas chromatograph connected to a nitrogen phosphorus and an electron capture detector, the other basic drugs as well as the acidic drugs were confirmed after the same derivatization procedures as in the screening methods. Alcohols were quantitated in triplicate by gas chromatography using three different kinds of columns. Although urine is the most important specimen for screening abused drugs, it has only limited use in forensic toxicology. The described system is most useful for analyzing a wide range of substances, including illicit drugs, benzodiazepines, barbiturates, antidepressants and phenothiazenes in forensic samples when urine is not available.

    Screening tests are widely used in medicine to assess the likelihood that members of a defined population have a particular disease. This article presents an overview of such tests including the definitions of key technical (sensitivity and specificity) and population characteristics necessary to assess the benefits and limitations of such tests. Several examples are used to illustrate calculations, including the characteristics of low dose computed tomography as a lung cancer screen, choice of an optimal PSA cutoff and selection of the population to undergo mammography. The importance of careful consideration of the consequences of both false positives and negatives is highlighted. Receiver operating characteristic curves are explained as is the need to carefully select the population group to be tested. PMID:25264934

    Introduction Tablet computer-based screening may have the potential for detecting patients at risk for opioid abuse in the emergency department (ED). Study objectives were a) to determine if the revised Screener and Opioid Assessment for Patients with Pain (SOAPP®-R), a 24-question previously paper-based screening tool for opioid abuse potential, could be administered on a tablet computer to an ED patient population; b) to demonstrate that >90% of patients can complete the electronic screener without assistance in <5 minutes and; c) to determine patient ease of use with screening on a tablet computer. Methods This was a cross-sectional convenience sample study of patients seen in an urban academic ED. SOAPP®-R was programmed on a tablet computer by study investigators. Inclusion criteria were patients ages ≥18 years who were being considered for discharge with a prescription for an opioid analgesic. Exclusion criteria included inability to understand English or physical disability preventing use of the tablet. Results 93 patients were approached for inclusion and 82 (88%) provided consent. Fifty-two percent (n=43) of subjects were male; 46% (n=38) of subjects were between 18–35 years, and 54% (n=44) were >35 years. One hundred percent of subjects completed the screener. Median time to completion was 148 (interquartile range 117.5–184.3) seconds, and 95% (n=78) completed in <5 minutes. 93% (n=76) rated ease of completion as very easy. Conclusions It is feasible to administer a screening tool to a cohort of ED patients on a tablet computer. The screener administration time is minimal and patient ease of use with this modality is high. PMID:25671003

    Cancer is increasingly more common. Several tests for the diagnosis and treatment of cancer in companion animals have been developed. Screening tests discussed include those for lymphoid neoplasia, hemangiosarcoma, and transitional cell carcinoma of the bladder. None of these tests should be used in isolation for diagnosis. Vincristine and doxorubicin are mainstays in the treatment of canine lymphoma. However, it is important and accepted practice to test individuals of predisposed breeds for this mutation before administering these drugs in a lymphoma protocol. PMID:25174904

    2003-06-01

    The Early Alert Alzheimer's Home Screening Test (AHST) is a variant of the Smell Identification Test (SIT) and the Cross-Cultural Smell Identification Test (CC-SIT), and recently became available for purchase by the general public. The validity and the practical utility of routine screening for individuals with asymptomatic cognitive impairment has not been established. There are considerable specific methodological concerns regarding the use of the AHST including the association of olfactory impairment with (a) age in the absence of cognitive impairment, (b) numerous acute and/or chronic medical conditions, and (c) lifestyle habits and social and/or demographic variables. General public misunderstanding of the difference between a screening and a diagnostic test, primary care physicians' frequent confusion about follow-up mechanisms for newly diagnosed patients with dementia, the possible lack of perceived counseling options for those self-diagnosed, and abuse of test findings create distinct possibilities for misuse of this test. The marketing of the AHST and its general use without appropriate public health educational safeguards is inappropriate and may be unethical. PMID:12810892

    A comparison is made between the General Health Questionnaire (GHQ) and the Symptom Checklist (SCL) as psychiatric screening tests in community-based research projects. Both are shown to correlate equally well with independent clinical assessment, and the differences between them mainly reside in the form of their response scales. The GHQ works best as a screening test, since it has fewer false positives associated with its use, but it may miss those with long-standing disorders. The SCL tends not to miss long-standing disorders and furnishes diagnostic sub-scales if these are required. Both tests function better with men than with women and with whites than with blacks, but neither is affected by social class or age of the respondent. The study revealed high correlations between the symptoms of anxiety and depression, and indicated some possible differences between the symptom clusters seen in whites and in blacks. PMID:938806

    Neuropsychological tests are instruments used to diagnose a variety of cognitive conditions. This article will review a few of the brief scales commonly used in screening for dementia. It will also discuss the properties of and problems with some of the brief scales that are commonly used to screen African Americans for dementia, highlighting the various biases. The Mini-Mental State Examination (MMSE) is the most widely known and utilized cognitive impairment instrument in the United States. Whether or not it is biased to race after adjusting the scores for educational attainment remains controversial. The Blessed Information-Memory-Concentration Test (BIMC), Blessed Orientation-Memory-Concentration Test (BOMC), Short Portable Mental Status Questionnaire (SPMSQ), and Neurobehavioral Cognitive Status Examination (NCSE) are other screening tests used to diagnose dementia. Some of these tests have been found to misclassify many more African Americans as demented compared to the proportion of whites that are misclassified. The Cambridge Cognitive Examination (CAMCOG) is the only brief neuropsychological scale designed to actually diagnose early dementia, but it is not known if it is biased for African Americans.

    A pediatric patient was assaulted while being treated at a Level 1 pediatric trauma center, prompting a Centers for Medicare & Medicaid Services site visit. The process of screening for physical abuse and protection of patients was reevaluated and revised, and a new guideline was implemented and shared with referral hospitals. During this same time period, 13 referral hospitals participated in an unrelated federally funded study determining the impact of recognition and care of injured children in states with and without a pediatric emergency care facility recognition program. A pre-post study analysis revealed that screening for abuse doubled during this time period. PMID:26953535

    The Company introduced its Substance Abuse Program in February 1995 to cover all of the workforce including contractors in its operations. This program supports the safety program in terms of loss prevention, accident prevention and employee performance problems which may be related to substance abuse in the workplace. The company has many work locations with distinctly different operational characteristics. It employs over 1,100 employees and 1,100 contractors of which 1,000 personnel are employed on offshore facilities; this requires a major logistics effort. The program is designed to be fair and equitable. The individuals to be tested are selected by a PC driven random number program. The testing program is treated confidentially. The chain of custody is carefully controlled. Disciplinary action complies with Thai labor law. The results of the twelve month program show that a total of 1,083 breath alcohol and 1,200 urine samples were tested for all causes. The results showed that only 0.55% and 1.25% of breath alcohol and urine samples respectively were positive.

    Twelve adolescent males with a history of chronic solvent abuse were compared with 12 delinquent controls on a battery of neuropsychological tests. Toluene was the active constituent most commonly abused. Solvent abusers tended to have lower overall intelligence test scores. On the Bexley Maudsley Automated Screening Test, the solvent abusers scored significantly lower on tests involving visual processing, especially the Symbol Digit Coding test. These results are cautiously interpreted as indicating that chronic solvent abuse carries an increased risk of cognitive impairment. PMID:2311197

    Although most women find it difficult to provide care to an older family member, some women face additional challenges and health risks because the care recipient is abusive or aggressive toward them. This study tested a 12-week psychoeducative nursing intervention intended to decrease the frequency and intensity of physical and verbal/psychological aggression toward older caregiving wives and daughters by care recipients and improve selected abuse-related outcomes. The intervention, which focused on pattern identification, advocacy counseling, reframing of the caregiving situation, and nonconfrontational caregiving strategies, was individualized and highly interactive with emphasis placed on mutual problem solving and mutual planning. Subjects included women older than 50 who provided care to elders older than 55. Subjects were randomly assigned to group (intervention, N = 38; control, N = 45) and data collectors were "blinded" to group assignment. Findings indicated the intervention significantly reduced frequency of verbal/psychological aggression, and feelings of anger for caregivers providing care to fathers or husbands. It was not effective for caregivers providing care to mothers, and it did not reduce burden. Implications for nursing include raising awareness about the special vulnerabilities of older caregivers, providing provocative new information about the gender-based power dynamics in caregiving situations and underscoring the need for nurses to assume a stronger leadership role in building science with regard to family caregiving.

    Diesfeldt, H F A

    2009-10-01

    The Cognitive Screening Test (CST) is a twenty-item orientation questionnaire in Dutch, that is commonly used to evaluate cognitive impairment. This study applied Mokken Scale Analysis, a non-parametric set of techniques derived from item response theory (IRT), to CST-data of 466 consecutive participants in psychogeriatric day care. The full item set and the standard short version of fourteen items both met the assumptions of the monotone homogeneity model, with scalability coefficient H = 0.39, which is considered weak. In order to select items that would fulfil the assumption of invariant item ordering or the double monotonicity model, the subjects were randomly partitioned into a training set (50% of the sample) and a test set (the remaining half). By means of an automated item selection eleven items were found to measure one latent trait, with H = 0.67 and item H coefficients larger than 0.51. Cross-validation of the item analysis in the remaining half of the subjects gave comparable values (H = 0.66; item H coefficients larger than 0.56). The selected items involve year, place of residence, birth date, the monarch's and prime minister's names, and their predecessors. Applying optimal discriminant analysis (ODA) it was found that the full set of twenty CST items performed best in distinguishing two predefined groups of patients of lower or higher cognitive ability, as established by an independent criterion derived from the Amsterdam Dementia Screening Test. The chance corrected predictive value or prognostic utility was 47.5% for the full item set, 45.2% for the fourteen items of the standard short version of the CST, and 46.1% for the homogeneous, unidimensional set of selected eleven items. The results of the item analysis support the application of the CST in cognitive assessment, and revealed a more reliable 'short' version of the CST than the standard short version (CST14).

    We hand out a list of screening tests for discharge support (the screening) to all patients upon admission, so that they can receive an early discharge. Implementing the screening as a balanced score card (BSC) evaluation index of the work performance by the nursing division, we were able to screen more than 40% of newly admitted patients immediately after the introduction of the screening. When more than two items of the screening questionnaire were checked, a discharge support intervention was introduced. Patients who checked items on the screening questionnaire have tended to request discharge support within a week of admission. PMID:16422486

    1999-01-01

    A large number of chemicals induce or exacerbate autoimmune-like diseases in man. Because of the complexity of processes involved, these adverse effects are often if not always missed in standard toxicity testing. To date no validated and generally applicable predictive animal model exists and only a few chemicals have actually been shown to induce adverse autoimmune effects in certain animals. The popliteal lymph node assay (PLNA) is a very promising animal test to (pre)screen for systemic immunosensitizing, including autoimmunogenic potential. This review describes the essentials of the various PLNAs against the background of current understanding of chemically induced systemic immunostimulation. The most simple primary PLNA measures enlargement of the popliteal lymph node 6-8 days after subcutaneous injection of a chemical into the footpad. The primary PLNA can distinguish between immunostimulating (both sensitizers and irritants) and innocent chemicals but does not assess the involvement of T cells or immunosensitization. For this, but also for elucidation of relevant mechanisms, detection of anamnestic responses in secondary PLNAs or responses to reporter antigens in the modified PLNA are suitable. To date over 100 compounds (drugs and environmental pollutants) have been tested, and results show a good correlation with reported immunostimulating (both autoimmunogenic and allergic) potential. Importantly, no false-negative chemicals were detected if metabolism was considered. The various types of the PLNA, but in particular the secondary and modified PLNAs, await extensive validation before they can be recommended as a standard test for autoimmunogenic potential.

    Past research has examined links among animal abuse, child maltreatment, and intimate partner violence and demonstrated the importance of addressing the needs of both human and animal victims. We hypothesized that there might be a similar link between animal abuse and older adult welfare issues. As a first step in the earlier research was the development of a screening protocol that shed light on the link between domestic violence and animal abuse, we decided to follow a similar route to explore this new topic by asking state government representatives about their experiences, if any, with this topic. Here we report the results of a national survey of state Adult Protective Services agencies regarding their protocols for assessing animal welfare issues in the context of older adult maltreatment. We also describe a model assessment protocol we developed in collaboration with the Utah Division of Aging and Adult Services. PMID:22206511

    Adults with intellectual disabilities need thoughtful, well-coordinated primary care from family physicians. However, evidence-based screening recommendations are lacking. We examined screening recommendations for common preventable conditions using the US Preventative Service Task Force guidelines. We also reviewed the literature about the prevalence of these conditions in adults with intellectual disabilities. Obesity, osteoporosis, and smoking are more prevalent in adults with intellectual disabilities, and enhanced screening for these conditions is recommended. Abnormal Papanicolaou smears and cervical cancer are less common in adults with intellectual disabilities and screening recommendations should be individualized. We also discussed strategies to make screening procedures less stressful for these patients. PMID:17615421

    The study examines the role of patient colorectal cancer (CRC) screening test preference and CRC screening uptake in an insured, urban minority population. Study subjects were enrolled in a randomized controlled trial to promote CRC screening. The interventions were educational, with an emphasis on colonoscopy screening. Subjects were 50+ years of age, fully insured for CRC screening, and out of compliance with current CRC screening recommendations. This paper includes those who answered a question about CRC screening test preference and indicated that they intended to receive such a test in the coming year (n = 453). CRC screening uptake was ascertained from medical claims data. Regardless of test preference, few received CRC screening (22.3 %). Those preferring the home stool test (HST) were less likely to get tested than those preferring a colonoscopy (16.6 vs 29.9 %, χ(2) = 9.9, p = .002). Preference for HST was more strongly associated with beliefs about colonoscopy than with knowledge about colonoscopy. In the context of an RCT emphasizing colonoscopy screening for CRC, patients expressing a preference for HST are at heightened risk of remaining unscreened. Colonoscopy should be recommended as the preferred CRC test, but HSTs should be accessible and encouraged for patients who are averse to colonoscopy.Clinical trials.gov: Identifier: NCT02392143.

    Exhaled breath is being developed as a possible specimen for drug testing based on the collection of aerosol particles originating from the lung fluid. The present study was aimed to evaluate the applicability of exhaled breath for drugs of abuse testing in criminal justice settings. Particles in exhaled breath were collected with a new device in parallel with routine urine testing in two Swedish prisons, comprising both genders. Urine screening was performed according to established routines either by dipstick or by immunochemical methods at the Forensic Chemistry Laboratory and confirmations were with mass spectrometry methods. A total of 247 parallel samples were studied. Analysis of exhaled breath samples was done with a sensitive mass spectrometric method and identifications were made according to forensic standards. In addition tested subjects and personnel were asked to fill in a questionnaire concerning their views about drug testing. In 212 cases both the urine and breath testing were negative, and in 22 cases both urine and breath were positive. Out of 6 cases where breath was negative and urine positive 4 concerned THC. Out of 7 cases where, breath was positive and urine negative 6 concerned amphetamine. Detected substances in breath comprised: amphetamine, methamphetamine, THC, methylphenidate, buprenorphine, 6-acetylmorphine, cocaine, benzoylecgonine, diazepam and tramadol. Both the prison inmates and staff members reported breath testing to be preferable due to practical considerations. The results of this study documented that drug testing using exhaled breath provided as many positives as urine testing despite an expected shorter detection window, and that the breath sampling procedure was well accepted and provided practical benefits reported both by the prison inmates and testing personnel.

  1. Childhood abuse and criminal behavior: testing a general strain theory model.

    PubMed

    Watts, Stephen J; McNulty, Thomas L

    2013-10-01

    This article draws on general strain theory (GST) to develop and test a model of the childhood abuse-crime relationship. Using data from the National Longitudinal Study of Adolescent Health (Add Health),(1) we find that early childhood physical and sexual abuse are robust predictors of offending in adolescence, for the full sample and in equations disaggregated by gender. GST is partially supported in that the effects of childhood physical abuse on offending for both females and males are mediated by an index of depression symptoms, whereas the effect of sexual abuse among females appears to be mediated largely by closeness to mother. The effect of childhood sexual abuse among males, however, is more robust than among females and it persists despite controls for low self-control, ties to delinquent peers, school attachment, and closeness to mother. Theoretical implications of the findings are discussed. PMID:23787294

    Hair testing was used to investigate the prevalence of unsuspected exposure to drugs of abuse in a group of children presenting to an urban paediatric emergency department without suggestive signs or symptoms. Hair samples were obtained from 114 children between 24 months and 10 years of age attending the emergency room of Hospital del Mar in Barcelona, Spain. Hair samples from the accompanying parent were also collected. The samples were analyzed for the presence of opiates, cocaine, amphetamines, and cannabinoids by ultra-performance liquid chromatography-tandem mass spectrometry. Parental sociodemographics and possible drug of abuse history were recorded. Hair samples from twenty-three children (20.1%) were positive for cocaine (concentration range 0.15-3.81 ng/mg hair), those of thirteen children (11.4%) to cannabinoids (D9-THC concentration range 0.05-0.54 ng/mg hair), with four samples positive to codeine (0.1-0.25 ng/mg hair), one positive for 2.09 ng methadone per mg hair and one to 6-MAM (0.42 ng/mg hair) and morphine (0. 15 ng/mg hair) . In 69.5 and 69.2% of the positive cocaine and cannabinoids cases respectively, drugs was also found in the hair of accompanying parent. Parental sociodemographics were not associated with children exposure to drugs of abuse. However, the behavioural patterns with potential harmful effects for the child's health (e.g., tobacco smoking, cannabis, benzodiazepines and/or antidepressants use) were significantly higher in the parents of exposed children. In the light of the obtained results (28% overall children exposure to drugs of abuse) and in agreement with 2009 unsuspected 23% cocaine exposure in pre-school children from the same hospital, we support general hair screening to disclose exposure to drugs of abuse in children from risky environments to provide the basis for specific social and health interventions.

    The hypothesis that job loss affects the incidence of clinically significant alcohol abuse is tested using panel data from the Epidemiologic Catchment Area project. Results suggest that the incidence of clinically significant alcohol abuse is greater among those who have been laid off than among those who have not. However, employed persons in communities in which total employment is unexpectedly low are at reduced risk of becoming alcohol abusers. The implications of the results for economic policy and for mental health services are discussed briefly. PMID:7989666

    This report presents an analysis of 507 abnormal retinal reflex images taken of Huntsville kindergarten and first grade students. The retinal reflex images were obtained by using an MSFC-developed Generated Retinal Reflex Image System (GRRIS) photorefractor. The system uses a 35 mm camera with a telephoto lens with an electronic flash attachment. Slide images of the eyes were examined for abnormalities. Of a total of 1835 students screened for ocular abnormalities, 507 were found to have abnormal retinal reflexes. The types of ocular abnormalities detected were hyperopia, myopia, astigmatism, esotropia, exotropia, strabismus, and lens obstuctions. The report shows that the use of the photorefractor screening system is an effective low-cost means of screening school children for abnormalities.

    Background Understanding what factors contribute to alcohol abuse in resource-poor countries is important given its adverse health consequences. Past research shows that social peers influence substance abuse, suggesting that the social environment may be an effective target for reducing alcohol abuse across a population. This study investigates the determinants of alcohol use and abuse in rural Zimbabwe and tests a Community Popular Opinion Leader (CPOL) community-based intervention partly directed at reducing alcohol abuse. Methods Tests were conducted on the impact of the CPOL intervention on alcohol use patterns across communities in rural Zimbabwe over three waves from 2003 to 2007, including community- and individual-level tests using data based on in-person interviews of adult men and women (ages 18 to 30; N = 5,543). Data were analyzed using paired-sample t-tests, as well as logistic and ordinary least-squares regression with random effects. Results Higher drinking (any use, more frequent use, greater quantity, and/or frequent drunkenness) was generally associated with being male, older, not married, more highly educated, of Shona ethnicity, away from home frequently, employed, having no religious affiliation, or living in areas with a higher crude death rate or lower population density. Over the study period, significant declines in alcohol use and abuse were found in intervention and control sites at relatively equal levels. Conclusions Although no support was found for the effectiveness of the CPOL study in reducing alcohol abuse, Zimbabwe is similar to other countries in the impact of socio-demographic and cultural factors on alcohol use and abuse.

    Background Understanding which attributes of colorectal cancer (CRC) screening tests drive older adults’ test preferences and choices may help improve decision making surrounding CRC screening in older adults. Materials and methods To explore older adults’ preferences for CRC-screening test attributes and screening tests, we conducted a survey with a discrete choice experiment (DCE), a directly selected preferred attribute question, and an unlabeled screening test-choice question in 116 cognitively intact adults aged 70–90 years, without a history of CRC or inflammatory bowel disease. Each participant answered ten discrete choice questions presenting two hypothetical tests comprised of four attributes: testing procedure, mortality reduction, test frequency, and complications. DCE responses were used to estimate each participant’s most important attribute and to simulate their preferred test among three existing CRC-screening tests. For each individual, we compared the DCE-derived attributes to directly selected attributes, and the DCE-derived preferred test to a directly selected unlabeled test. Results Older adults do not overwhelmingly value any one CRC-screening test attribute or prefer one type of CRC-screening test over other tests. However, small absolute DCE-derived preferences for the testing procedure attribute and for sigmoidoscopy-equivalent screening tests were revealed. Neither general health, functional, nor cognitive health status were associated with either an individual’s most important attribute or most preferred test choice. The DCE-derived most important attribute was associated with each participant’s directly selected unlabeled test choice. Conclusion Older adults’ preferences for CRC-screening tests are not easily predicted. Medical providers should actively explore older adults’ preferences for CRC screening, so that they can order a screening test that is concordant with their patients’ values. Effective interventions are

    There is an increasing interest in screening instruments to detect intellectual disability (ID) in a quick and accurate way in mental health services as well as in the criminal justice system in order to provide appropriate support for people with undetected needs caused by ID. An instrument that has been proven to be useful in both settings is the Hayes Ability Screening Index (HASI). This study assessed the validity of the Dutch version of the HASI in persons with a substance abuse problem residing in mental health services, whether or not mandated to treatment by court order. The HASI was conducted along with the Wechsler Adult Intelligence Scale III as the criterion for validity to 90 participants. Additionally, the influence of psychiatric disorder and medication use on the HASI result was examined. A significant positive relationship was found between the two instruments, demonstrating convergent validity. Using a Receiver Operating Characteristic (ROC) curve analysis, the discriminative ability of the HASI with a cut-off score of 85 was found to be adequate, yielding in a good balance between sensitivity and specificity. The HASI was not distorted by the presence of the substance abuse problem or other psychiatric illnesses and medication did not influence the HASI scores in this study. These findings indicate that the HASI provides a time-efficient and resource-conscious way to detect ID in persons with a substance problem, thus addressing a critical need in mental health settings.

    A review of fraud and abuse challenge against the Natural Gas Policy Act (NGPA) section 601, which allows the Federal Energy Regulatory Commission to control the prices pipeline companies pay. The author explores the statutory background of the case, FERC's authority to interpret provisions of the NGPA in the area of take-or-pay problems, and court opinions. He concludes by outlining approaches for applying the fraud and abuse test, and views the guaranteed pass-through exception of fraud, abuse, or similar grounds as a valuable enforcement tool for FERC. As the terms become better defined, pipelines will be able to structure their business activities to avoid situations likely to lead to fraud or abuse charges. Both FERC and the natural gas industry will benefit from further development of the standard.

    1997-01-01

    Drug abuse is highly correlated with criminal behavior. The typical drug-using criminal commits hundreds of crimes per year. The crime rate cannot be significantly reduced without a reduction in the percentage of the population abusing drugs and alcohol. Accurate and timely estimation of that percentage is important for policy decisions concerning crime control, public health measures, allocation of intervention resources for prevention and treatment, projections of criminal justice needs, and the evaluation of policy effectiveness. Such estimation is particularly difficult because self reporting is unreliable; and physical testing has to date required blood or urine analysis which is expensive and invasive, with the result that too few people are tested. MIKOS Ltd. has developed a non-contact, passive technique with the potential for automatic, real- time screening for drug and alcohol use. The system utilizes thermal radiation which is spontaneously and continuously emitted by the human body. Facial thermal patterns and changes in patterns are correlated with standardized effects of specific drugs and alcohol. A portable system incorporating the collection and analysis technique can be used episodically to collect data for estimating drug and alcohol use by general unknown populations such as crowds at airports, or it can be used for repetitive routine screening of specific known groups such as airline pilots, military personnel, school children, or persons on probation or parole.

    A new procedure is described which was recently developed to quantify loading uniformity of nickel and cadmium plates and to screen finished electrodes prior to cell assembly. The technique utilizes the initial solubility rates of the active material in a standard chemical deloading solution at fixed conditions. The method can provide a reproducible indication of plate loading uniformity in situations where high surface loading limits the free flow of deloading solution into the internal porosity of the sinter plate. A preliminary study indicates that 'good' cell performance is associated with higher deloading rates.

    A defining feature of drug addiction is persistent drug use despite long-term adverse consequences. This study examined the performance of drug abusers on a neuropsychological test that requires evaluation of long-term outcomes in the presence of a complex set of mixed reward/punishment contingencies (the Gambling Task). In order to control for generalized deficits related to choice and planning, subjects were also administered the Wisconsin Card Sorting Task. Thirty polysubstance abusers were compared to a comparison group of 24 subjects who did not use illicit drugs of abuse. Drug abusers performed much more poorly on the Gambling Task (net score = 10.2 +/- 4.7, mean +/- s.e.m.) than controls (26.0 +/- 5.3), but did not differ from controls on the Wisconsin Card Sorting Task. The results show that drug abusers are more likely to make maladaptive decisions in the Gambling Task that result in long-term losses exceeding short-term gains. These findings indicate that the Gambling Task may be a useful model in laboratory studies of cognitive dysfunctions associated with drug abuse. PMID:10838152

    The present study assesses the results of cervical cancer (CC) screening over two 3-year periods (2008–2010 and 2011–2013) by comparing two screening tests [Papanicolaou (Pap) and human papillomavirus (HPV) tests] and two screening methods (organized and spontaneous). The study population includes women aged 25–64 years who underwent CC screening between 2008 and 2010 and/or 2011 and 2013, divided into those who responded to an invitation letter (organized screening) and those who spontaneously underwent testing at a public or private facility (non-programmed screening). Between 2008 and 2010, the response rates increased from 27.7% in 2008 to 44.5% in 2009 and 67.6% in 2010 (P<0.001). Women aged 25–34 years had the lowest response rate, whereas respondents were more frequent among women aged 35–44 and 45–54 years. Significant differences (P<0.001) were identified between organized and spontaneous screening test results with regard to diagnostic categories high-grade squamous intraepithelial lesion (50.5 vs. 49.5%), low-grade squamous intraepithelial lesion (42.8 vs. 57.2%) and undetermined lesion atypical glandular cells (AGC; 57.5 vs. 42.5%) or atypical squamous cells of undetermined significance (ASC-US; 54.2 vs. 45.8%). Compared with spontaneous screening, the organized programme resulted in a larger number of women screened for CC; it reduced the frequency of undetermined diagnoses (AGC, ASC-US), and identified a larger number of high-grade lesions.

    This manual defines a complete body of abuse tests intended to simulate actual use and abuse conditions that may be beyond the normal safe operating limits experienced by electrical energy storage systems used in electric and hybrid electric vehicles. The tests are designed to provide a common framework for abuse testing various electrical energy storage systems used in both electric and hybrid electric vehicle applications. The manual incorporates improvements and refinements to test descriptions presented in the Society of Automotive Engineers Recommended Practice SAE J2464 ''Electric Vehicle Battery Abuse Testing'' including adaptations to abuse tests to address hybrid electric vehicle applications and other energy storage technologies (i.e., capacitors). These (possibly destructive) tests may be used as needed to determine the response of a given electrical energy storage system design under specifically defined abuse conditions. This manual does not provide acceptance criteria as a result of the testing, but rather provides results that are accurate and fair and, consequently, comparable to results from abuse tests on other similar systems. The tests described are intended for abuse testing any electrical energy storage system designed for use in electric or hybrid electric vehicle applications whether it is composed of batteries, capacitors, or a combination of the two.

    Few reliable tests are available for screening people rapidly for vestibular disorders although such tests would be useful for a variety of testing situations. Balance testing is widely performed but of unknown value for screening. The goal of this study was to determine the value of tests of walking balance for screening people with vestibular impairments. We tested three groups of patients with known vestibular impairments: benign paroxysmal positional vertigo, unilateral vestibular weakness, and post-acoustic neuroma resection. We compared them to normal subjects. All subjects were independently ambulatory without gait aids. Subjects were tested on tandem walking (TW) with eyes open and eyes closed for 10 steps, walking with no additional head motions and with augmented head rotations in yaw for 7 m (WwHT), and an obstacle avoidance task, the Functional Mobility Test (FMT). Subjects wore a 3-D motion sensor centered at mid-torso to capture kinematic measures. Patients and normals differed significantly on some behavioral measures, such as the number of steps to perform TW, and on some but not all kinematic measures. ROC analyses, however, were at best only moderate, and failed to find strong differences and cut-points that would differentiate the groups. These findings suggest that although patients and normals differ in performance of these tests in some interesting ways the groups are not sufficiently different on these tests for easy use as screening tests to differentiate the populations.

    Purpose The aim of the current study is to test the validity and reliability of the Shame Questionnaire among traumatized girls in Lusaka, Zambia. Methods The Shame Questionnaire was validated through both classical test and item response theory methods. Internal reliability, criterion validity and construct validity were examined among a sample of 325 female children living in Zambia. Sub-analyses were conducted to examine differences in construct validity among girls who reported sexual abuse and girls who did not. Results All girls in the sample were sexually abused, but only 61.5% endorsed or reported that sexual abuse had occurred. Internal consistency was very good among the sample with alpha = .87. Criterion validity was demonstrated through a significant difference of mean Shame Questionnaire scores between girls who experienced 0–1 trauma events and more than one traumatic event, with higher mean Shame Questionnaire scores among girls who had more than one traumatic event (p = .004 for 0–1 compared to 2 and 3 events and p = .016 for 0–1 compared to 4+ events). Girls who reported a history of witnessing or experiencing physical abuse had a significantly higher mean Shame Questionnaire score than girls who did not report a history of witnessing or experiencing physical abuse (p<.0001). There was no significant difference in mean Shame Questionnaire score between girls who reported a sexual abuse history and girls who did not. Exploratory factor analysis indicated a two-factor model of the Shame Questionnaire, with an experience of shame dimension and an active outcomes of shame dimension. Item response theory analysis indicated adequate overall item fit. Results also indicate potential differences in construct validity between girls who did and did not endorse sexual abuse. Conclusions This study suggests the general utility of the Shame Questionnaire among Zambian girls and demonstrates the need for more psychometric studies in low and middle income

  6. Screening in the Dark: Ethical Considerations of Providing Screening Tests to Individuals When Evidence is Insufficient to Support Screening Populations

    2011-01-01

    During the past decade, screening tests using computed tomography (CT) have disseminated into practice and been marketed to patients despite neither conclusive evidence nor professional agreement about their efficacy and cost-effectiveness at the population level. This phenomenon raises questions about physicians’ professional roles and responsibilities within the setting of medical innovation, as well as the appropriate scope of patient autonomy and access to unproven screening technology. This article explores how physicians ought to respond when new screening examinations that lack conclusive evidence of overall population benefit emerge in the marketplace and are requested by individual patients. To this end, the article considers the nature of evidence and how it influences decision-making for screening at both the public policy and individual patient levels. We distinguish medical and ethical differences between screening recommended for a population and screening considered on an individual patient basis. Finally, we discuss specific cases to explore how evidence, patient risk factors and preferences, and physician judgment ought to balance when making individual patient screening decisions.

  7. Revision of the Word Association Test for assessing associations of patients reporting satanic ritual abuse in childhood.

    1998-11-01

    A growing number of psychiatric patients report satanic ritual abuse, prompting research into this controversial area. In the current study, the Word Association Test (WAT) was modified to assess experience with satanic abuse. Pilot work resulted in norms for two domains: normative and satanic. Female psychiatric patients were compared on their associations in two studies. Based on a sexual history, they were grouped into those reporting sexual abuse, those reporting satanic ritual abuse (SRA), and those without a history of sexual abuse (controls). In both studies, SRA patients gave significantly more total associations, significantly fewer normative associations, and significantly more satanic associations than did the other two groups. These results suggest that an experience base is shared by individuals reporting SRA that is not found in individuals who do not report satanic abuse (even if they do report sexual abuse). The implications of these findings are discussed from the perspective of arguments advanced by advocates and critics of SRA. PMID:9811130

    Bench scale (1 to 6 gram) methane cracking tests have been performed on a variety of pure elements, some alloys, and SAES{reg_sign} commercial getters St 101, St 198, St 707, St 737, and St 909 to determine methane cracking performance (MCP) of 5% methane in a helium carrier at 700 C, 101.3 kPa (760 torr) with a 10 sccm feed. The MCP was almost absent from some materials tested while others showed varying degrees of MCP. Re, Cr, V, Gd, and Mo powders had good MCP, but limited capacities. Nickel supported on kieselguhr (Ni/k), a Zr-Ni alloy, and the SAES{reg_sign} getters had good MCP in a helium carrier. The MCP of these same materials was suppressed in a hydrogen carrier stream and the MCP of the Zr-based materials was reduced by nitride formation when tested with a nitrogen carrier gas.

    A lubricant screening test fixture has been devised in order to satisfy the need to obtain lubricant performance data in a timely manner. This fixture has been used to perform short-term tests on potential lubricants for several spacecraft applications. The results of these tests have saved time by producing qualitative performance rankings of lubricant selections prior to life testing. To date, this test fixture has been used to test lubricants for 3 particular applications. The qualitative results from these tests have been verified by life test results and have provided insight into the function of various anti-wear additives.

    An in-situ corrosion censor facilitates coating development and screening by detecting the early stages of corrosion well before degradation is visible. Based on electrochemical impedance spectroscopy (EIS), the sensor extends the use of this established laboratory technique from immersion only to different accelerated test conditions (such as salt fog or humidity) and ambient service environments. By enabling a direct quantitative comparison of the early stages of coating deterioration and substrate corrosion that occur in laboratory accelerated tests and service or field conditions, the laboratory tests can be validated and coatings screened more quickly.

    Diagnosis of CGD is made by demonstrating absent or markedly reduced oxidase activity in stimulated neutrophils. The screening test proposed is based upon the naked eye evaluation of the reduction of NBT on a solid surface. It seems to be a useful tool for rapid and inexpensive detection of CGD patients, especially for large-scale screening purposes. The test was carried out on forty-five subjects: two males affected by CGD, three female carriers and forty healthy donors. The test confirmed the results obtained with flow cytometric and NBT assays. PMID:24067482

    Background Screening of aphasia in acute stroke is crucial for directing patients to early language therapy. The Language Screening Test (LAST), originally developed in French, is a validated language screening test that allows detection of a language deficit within a few minutes. The aim of the present study was to develop and validate two parallel German versions of the LAST. Methods The LAST includes subtests for naming, repetition, automatic speech, and comprehension. For the translation into German, task constructs and psycholinguistic criteria for item selection were identical to the French LAST. A cohort of 101 stroke patients were tested, all of whom were native German speakers. Validation of the LAST was based on (1) analysis of equivalence of the German versions, which was established by administering both versions successively in a subset of patients, (2) internal validity by means of internal consistency analysis, and (3) external validity by comparison with the short version of the Token Test in another subset of patients. Results The two German versions were equivalent as demonstrated by a high intraclass correlation coefficient of 0.91. Furthermore, an acceptable internal structure of the LAST was found (Cronbach's α = 0.74). A highly significant correlation (r = 0.74, p < 0.0001) between the LAST and the short version of the Token Test indicated good external validity of the scale. Conclusion The German version of the LAST, available in two parallel versions, is a new and valid language screening test in stroke. PMID:27194999

  20. Hand Test scores of panic disordered outpatients sexually abused as children.

    Zizolfi, S; Cilli, G; Concari, S; Colombo, G

    1997-12-01

    A history of childhood sexual abuse has been implicated in a variety of adult psychiatric disorders as more frequent in females than in males and in subjects with more prominent dissociative symptoms such as panic disorder. Previous research has varied greatly in terms of methods, measurement instruments, and reported findings. Recent studies, however, suggest that projective techniques may be useful in resolving some of these inconsistencies. The present study utilized the Hand Test to investigate the late effects of childhood sexual trauma in a group of authenticated cases of panic disordered adult outpatients sexually abused as children compared to a matched sample of presumably nonabused patients. No statistically significant differences on quantitative variables were obtained between the two groups, but the group of outpatients (n = 16) sexually abused as children showed a larger latency to the ninth card of the Hand Test (shock reaction). This may be a potentially useful index in investigating cases of suspected abuse and confirms Wagner's (1983) contention that Card IX has a psychosexual "pull" as documented also by Italian studies.

    Oestenstad, R K; Rose, V E

    1986-05-01

    The predictive ability of the K2 Asbestos Screening Test was determined by comparing the results obtained with the test and confirming analysis by polarizing light microscopy on 90 bulk insulation samples. The test yielded 38.9% true positives, 4.4% true negatives, 56.7% false positives and 0% false negatives. The proportion of false positives was significantly different from that reported by the researchers who developed the test and found that the test would not yield false positives. The results of this study are similar to those reported in a previous evaluation of the test. It was concluded that the screening test is not an effective screening tool because of the high proportion of false positives, as reflected by marginal values of specificity and positive predictive value. It was noted that problems with the test might result from failure of the wash steps to adequately remove positive interferences apparently associated with gypsum and mineral wool. Problems in interpreting color changes were noted also. PMID:3717007

    Background. Worldwide, colorectal cancer (CRC) is the third most common cancer in men and second most common in women. It is the fourth most common cause of cancer mortality. In the United States, CRC is the third most common cause of cancer and second most common cause of cancer mortality. Incidence and mortality rates have steadily fallen, primarily due to widespread screening. Methods. We conducted keyword searches on PubMed in four categories of CRC screening: stool, endoscopic, radiologic, and serum, as well as news searches in Medscape and Google News. Results. Colonoscopy is the gold standard for CRC screening and the most common method in the United States. Technological improvements continue to be made, including the promising “third-eye retroscope.” Fecal occult blood remains widely used, particularly outside the United States. The first at-home screen, a fecal DNA screen, has also recently been approved. Radiological methods are effective but seldom used due to cost and other factors. Serum tests are largely experimental, although at least one is moving closer to market. Conclusions. Colonoscopy is likely to remain the most popular screening modality for the immediate future, although its shortcomings will continue to spur innovation in a variety of modalities. PMID:26504799

    2016-07-12

    Surface enhanced Raman spectroscopy (SERS) has emerged as a promising technique for the rapid and ultrasensitive detection of molecular species such as drugs of abuse in biofluids. Yet, it remains a significant challenge to create a viable screening tool for multiple drug classes, owing to the lack of affinity of certain species for the SERS substrate and to the matrix interference in complex media. Here we report a protein tethering SERS approach, which blends plasmonic enhancement with facile drug binding, to engineer a rapid, label-free and versatile screening tool for narcotics. By exploiting the known binding attributes of human serum albumin, we determine the effective concentration of narcotics present in solution through differential enhancement of the spectral markers. In conjunction with chemometric methods, this approach not only enables unambiguous recognition of different drug classes, such as barbiturates, opiates, amphetamines and benzodiazepines, but also offers a lower limit of detection in comparison to direct SERS application. Through molecular docking simulations, we probe the mechanistic underpinnings of the protein tethering approach paving the way for narcotic detection in clinical samples in the near future.

    1996-12-01

    A recent review indicated that only one speech and language screening test (the Sentence Repetition Screening Test; SRST) designed for preschoolers has been successfully validated in a representative population. This study sought to replicate the SRST validation study using a somewhat younger age group and to compare predictive indices to typical measures of parent concern and teacher judgment. A sample of (N = 343) prekindergarten children (ages 54 to 66 months) attending school registration in the spring before kindergarten entry was tested with the SRST. A stratified sample of 76 returned for criteria testing within 2 months. Teacher ratings were obtained 5 months later. Outcome measures were standard language (Bankson and Illinois Test of Psycholinguistic Abilities) and speech articulation (Arizona) tests. With a prevalence of 11%, SRST prediction of language outcomes resulted in the following indices: sensitivity, .62; specificity, .91; predictive validity, .44; overreferral, 8.4%; and underreferral, 4%. Prediction of the articulation outcome with a prevalence of 11% resulted in indices as follows: sensitivity, .57; specificity, .95; predictive validity, .75; overreferral, 3.7%; and underreferral, 8.3%. Teacher ratings and a parent questionnaire (Speech and Language Screening Questionnaire) approached the same rate of prediction of articulation but with a higher overreferral rate. The predictive indices from the SRST exceeded the comparison measures for language outcomes. PMID:8960570

  13. [Electronic eikonometer: Measurement tests displayed on stereoscopic screen].

    Bourdy, C; James, Y

    2016-05-01

    We propose the presentation on a stereoscopic screen of the electronic eikonometer tests intended for analysis and measurement of perceptual effects of binocular disparity. These tests, so-called "built-in magnification tests" are constructed according to the same principle as those of preceding eikonometers (disparity variation parameters being included in each test presentation, which allows, for test observation and measurements during the examination, the removing of any intermediate optical system). The images of these tests are presented separately to each eye, according to active or passive stereoscopic screen technology: (1) Ogle Spatial Test to measure aniseikonia; (2) Fixation Disparity test: binocular nonius; (3) retinal correspondence test evaluated by nonius horopter; (4) stereoscopic test using Julesz' random-dot stereograms (RDS). All of these tests, with their variable parameters included, are preprogrammed by means of an associated mini-computer. This new system (a single screen for the presentation of tests for the right eye and left eye) will be much simpler to reproduce and install for all practitioners interested in the functional exploration of binocular vision. We develop the suitable methodology adapted to each type of examination, as well as manipulations to be performed by the operator. We then recall the possibilities for reducing aniseikonia thanks to some theoretical studies previously performed by matrix calculation of the size of the retinal images for different types of eye (emmetropia, axial or conformation anisometropia, aphakia) and for different means of correction (glasses, contact lenses, implants). Software for achieving these different tests is available, on request, at this address: eiconometre.electronique@gmail.com. PMID:27185662

    The Entry, Descent, and Landing (EDL) Technology Development Project has been tasked to develop Thermal Protection System (TPS) materials for insertion into future Mars Entry Systems. A screening arc jet test of seven rigid ablative TPS material candidates was performed in the Hypersonic Materials Environmental Test System (HYMETS) facility at NASA Langley Research Center, in both an air and carbon dioxide test environment. Recession, mass loss, surface temperature, and backface thermal response were measured for each test specimen. All material candidates survived the Mars aerocapture relevant heating condition, and some materials showed a clear increase in recession rate in the carbon dioxide test environment. These test results supported subsequent down-selection of the most promising material candidates for further development.

    This study compared abusive husbands with nonabusive, marital discordant husbands using six measures to ascertain certain etiological characteristics of abusers. Both groups completed the Jenkins Activity Survey for measuring type A behavior, the Short Michigan Alcoholism Screening Test, the Index of Self-Esteem, the Spence-Helmrich Attitudes Toward Women Scale, the Index of Marital Satisfaction, and a simple rating scale to access their perceptions of their wives' physical attractiveness. As predicted, abusers evidence significantly higher type A behaviors, higher problem drinking behaviors, more rigid attitudes toward women, lower marital satisfaction, and rated their wives as less attractive than did nonabusers. Inconsistent with the literature, however, no significant differences were discovered between the self-esteem of abusers and nonabusers. PMID:1780068

    Dynamic visual acuity (DVA) may be a useful indicator of the function of the vestibulo-ocular reflex (VOR) but most DVA tests involve active head motion in the yaw plane. During gait the passive, vertical VOR may be more relevant and passive testing would be less likely to elicit compensatory strategies. The goal of this study was to determine if testing dynamic visual acuity during passive vertical motion of the subject would differentiate normal subjects from patients with known vestibular disorders. Subjects, normals and patients who had been diagnosed with either unilateral vestibular weaknesses or were post-acoustic neuroma resections, sat in a chair that could oscillate vertically with the head either free or constrained with a cervical orthosis. They viewed a computer screen 2 m away that showed Landholt C optotypes in one of 8 spatial configurations and which ranged in size from 0.4 to 1.0 logMAR. They were tested while the chair was stationary and while it was moving. Scores were worse for both groups during the dynamic condition compared to the static condition. In the dynamic condition patients’ scores were significantly worse than normals’ scores. Younger and older age groups differed slightly but significantly; the sample size was too small to examine age differences by decade. The data suggest that many well-compensated patients have dynamic visual acuity that is as good as age-matched normals. Results of ROC analyses were only moderate, indicating that the differences between patients and normals were not strong enough, under the conditions tested, for this test to be useful for screening people to determine if they have vestibular disorders. Modifications of the test paradigm may make it more useful for screening potential patients. PMID:23000614

    2005-01-01

    This paper describes a rapid gas chromatographic/mass spectrometric (GC/MS) screening method for the detection of drugs of abuse and/or their metabolites in urine. Synthetic stimulants, opiates, cocaine metabolites, cannabinoids--and specifically the acid metabolite of tetrahydrocannabinol (THC-COOH)--can be simultaneously extracted by a single liquid/liquid separation step, at alkaline pH, and assayed as trimethylsilyl derivatives by GC/MS in SIM (selected ion monitoring) mode. All the analytes show a good linearity (R2 > 0.99 for most of the considered substances) in the range 25-1000 ng/mL, with a good reproducibility of both the retention times (CV% <0.7) and the relative abundances of the characteristic diagnostic ions (CV% <13). The limit of detection (LOD) of the method is 25 ng/mL of target compound in human urine for most of the substances investigated, 3 ng/mL for THC-COOH, and 10 ng/mL for norbuprenorphine. Validation of the method allows its application to different fields of forensic analytical toxicology, including antidoping analysis. PMID:15880665

  1. The current status of sweat testing for drugs of abuse: a review.

    PubMed

    De Giovanni, N; Fucci, N

    2013-01-01

    Sweat is an alternative biological matrix useful to detect drugs of abuse intake. It is produced by eccrine and apocrine glands originating in the skin dermis and terminating in secretory canals that flow into the skin surface and hair follicles. Since many years it has been demonstrated that endogenous and exogenous chemicals are secreted in this biological sample hence its collection and analysis could show the past intake of xenobiotics. From the seventies the excretion of drugs of abuse has been investigated in human skin excretion; later in nineties forensic scientists began to experiment some techniques to trap sweat for analyses. Even if the use of skin excretions for drug testing has been restricted mainly by difficulties in sample recovery, the marketing of systems for the sample collection has allowed successful sweat testing for several drugs of abuse. In the recent years sweat testing developed a noninvasive monitoring of drug exposure in various contexts as criminal justice, employment and outpatient clinical settings. This paper provides an overview of literature data about sweat drug testing procedures for various xenobiotics especially cocaine metabolites, opiates, cannabis and amphetamines. Issues related to collection, analysis and interpretation of skin excretions as well as its advantages and disadvantages are discussed. Moreover the chance to apply the technique to some particular situation such as workplace drug testing, drivers, doping or prenatal diagnosis, the comparison between sweat and other non conventional matrices are also reviewed. According to literature data the analysis of sweat may be usefully alternative for verifying drug history and for monitoring compliance. PMID:23244520

    Substance use disorders are overrepresented in incarcerated male populations. Cost- effective screening for alcohol and substance use problems among incarcerated populations is a necessary first step forward intervention. The Alcohol, Smoking, and Substance Involvement Screening Test (ASSIST) holds promise because it has strong psychometric properties, requires minimal training, is easy to score, is available in the public domain but, because of complicated skip patterns, cannot be self-administered. This study tests the feasibility, reliability, and validity of using computer-administered self-interviewing (CASI) versus interviewer-administered interviewing (IAI) to screen for substance use problems among incarcerated men using the ASSIST. A 2 X 2 factorial design was used to randomly assign 396 incarcerated men to screening modality. Findings indicate that computer screening was feasible. Compared to IAI, CASI produced equally reliable screening information on substance use and symptom severity, with test-retest intraclass correlations for ASSIST total and substance-specific scores ranging from 0.7 to 0.9, and ASSIST substance-specific scores and a substance abuse disorder diagnosis based on the Structured Clinical Interview (SCID) were significantly correlated for IAI and CASI. These findings indicate that data on substance use and symptom severity using the ASSIST can be reliably and validly obtained from CASI technology, increasing the efficiency by which incarcerated populations can be screened for substance use problems and, those at risk, identified for treatment.

Cost-effective screening for alcohol and substance use problems among incarcerated populations is a necessary first step forward intervention. The Alcohol, Smoking, and Substance Involvement Screening Test (ASSIST) holds promise because it has strong psychometric properties, requires minimal training, is easy to score, is available in the public domain but, because of complicated skip patterns, cannot be self-administered. This study tests the feasibility, reliability, and validity of using computer-administered self-interviewing (CASI) versus interviewer-administered interviewing (IAI) to screen for substance use problems among incarcerated men using the ASSIST. A 2×2 factorial design was used to randomly assign 396 incarcerated men to screening modality. Findings indicate that computer screening was feasible. Compared to IAI, CASI produced equally reliable screening information on substance use and symptom severity, with test-retest intraclass correlations for ASSIST total and substance-specific scores ranging from 0.7 to 0.9, and ASSIST substance-specific scores and a substance abuse disorder diagnosis based on the Structured Clinical Interview (SCID) were significantly correlated for IAI and CASI. These findings indicate that data on substance use and symptom severity using the ASSIST can be reliably and validly obtained from CASI technology, increasing the efficiency by which incarcerated populations can be screened for substance use problems and, those at risk, identified for treatment.

    Background A comparative effectiveness intervention by this team improved initial fecal occult blood testing (FOBT) rates from 3% to 53% among community clinic patients. The purpose of this study was to evaluate the effectiveness and costs associated with a literacy-informed intervention on repeat FOBT testing. Methods Between 2008 and 2011, a three-arm quasi-experiential comparative effectiveness evaluation was conducted in 8 community clinics in Louisiana. Clinics were randomly assigned to receive: enhanced care, a screening recommendation and FOBT kit annually; a brief educational intervention where patients additionally received a literacy appropriate pamphlet and simplified FOBT instructions; or nurse support where a nurse manager provided the education and followed up with phone support. In year 2 all materials were mailed. The study consisted of 461 patients, ages 50–85, with a negative initial FOBT. Results Repeat FOBT rates were 38% enhanced care, 33% education, and 59% with nurse support (p=0.017). After adjusting for age, race, gender, and literacy, patients receiving nurse support were 1.46 times more likely to complete repeat FOBT screening than those receiving education (95% CI 1.14–1.06, p=0.002) and 1.45 times more likely than those in enhanced care but this was not significant (95% CI 0.93–2.26 p=0.10). The incremental cost per additional person screened was $2,450 for nurse over enhanced care. Conclusion A mailed pamphlet and FOBT with simplified instructions did not improve annual screening. Impact Telephone outreach by a nurse manager was effective in improving rates of repeat FOBT yet this may be too costly for community clinics. PMID:24192009

    Background The oral mucosa is constantly exposed to several irritants and allergens including dental materials, but the role of contact allergy in oral disease is obscure. Objective To analyze positive patch test results in patients with oral diseases and evaluate the clinical relevance of oral diseases with contact allergy to dental materials. Methods We retrospectively analyzed patch test results with dental screening series in 44 patients with oral disease from 2004~2011. Results Oral diseases included oral lichen planus (54.5%), cheilitis (27.3%), burning mouth syndrome (9.1%), and others (9.1%). Thirty-one of 44 patients (70.5%) had positive reactions to one or more allergens. The most commonly detected allergens were gold sodium thiosulfate (25.0%) and nickel sulfate (25.0%), followed by potassium dichromate (22.7%), cobalt (15.9%), palladium (6.8%), mercury (4.5%), copper (4.5%), and methylhydroquinone (4.5%). Six of 24 patients with oral lichen planus had a symptom in areas adjacent to dental materials and positive patch test reactions to allergens contained in the suspected dental materials. Conclusion Patch tests with dental screening series are worth considering for oral diseases, especially for oral lichen planus. PMID:26273153

    Objective To improve the test standards for a version of the Romberg test and to determine if measuring kinematic variables improved its utility for screening. Study design Healthy controls and patients with benign paroxysmal positional vertigo, postoperative acoustic neuroma resection, and chronic peripheral unilateral weakness were compared. Methods Subjects wore Bluetooth-enabled inertial motion units while standing on the floor or medium density, compliant foam, with eyes open or closed, with head still or moving in pitch or yaw. Dependent measures were time to perform each test condition, number of head movements made, and kinematic variables. Results Patients and controls did not differ significantly with eyes open or with eyes closed while on the floor. With eyes closed, on foam, some significant differences were found between patients and controls, especially for subjects older than age 59. Head movement conditions were more challenging than head still. Significantly fewer patients than controls could make enough head movements to obtain kinematic measures. Kinematics indicated that lateral balance control is significantly reduced in these patients compared to controls. Receiver Operator Characteristics and sensitivity/specificity analyses showed moderately good differences with older subjects. Conclusion Tests on foam with eyes closed, with head still or moving, may be useful as part of a screening battery for vestibular impairments, especially for older people. PMID:23877965

    Objective Few tests of functional motor behavior are useful for rapidly screening people for lower extremity peripheral neuropathy. The goal of this study was to improve the widely used Tandem Walking test (TW). Methods We tested adult normals and ambulatory peripheral neuropathy patients (PN) with eyes open and eyes closed, while they performed TW on industrial carpeting, in sock-covered feet. Each subject wore a torso-mounted inertial motion unit to measure kinematic data. PN subjects’ data were also compared to historical data on patients with vestibular impairments (VI). Results The normal and PN groups differed significantly on TW on the number of steps completed. PN and VI data also differed significantly on both visual conditions. Kinematic data showed that PN patients were more unstable than normals. For the number of steps taken during the eyes open condition receiver operating characteristic (ROC) values were only 0.81. For the number of steps taken during the eyes closed condition, however, ROC=0.88. Although not optimal, this ROC value is better. Sensitivity and specificity at a cut-off of 2 steps were 0.81 and 0.92, respectively, and at a cut-off of 3 steps was 0.86 and 0.75, respectively. ROC values for kinematic data were all < 0.8 and, when combined with the ROC value for the number of steps, the total ROC value did not improve appreciably. Conclusions Although not ideal for screening patients who may have peripheral neuropathy, counting the number of steps during TW is a quick and useful clinical test. TW is most sensitive to peripheral neuropathy patients when they are tested with eyes closed. PMID:24096950

  14. Noninvasive prenatal screening or advanced diagnostic testing: caveat emptor.

    PubMed

    Evans, Mark I; Wapner, Ronald J; Berkowitz, Richard L

    2016-09-01

    The past few years have seen extraordinary advances in prenatal genetic practice led by 2 major technological advances; next-generation sequencing of cell-free DNA in the maternal plasma to noninvasively identify fetal chromosome abnormalities, and microarray analysis of chorionic villus sampling and amniotic fluid samples, resulting in increased cytogenetic resolution. Noninvasive prenatal screening of cell-free DNA has demonstrated sensitivity and specificity for trisomy 21 superior to all previous screening approaches with slightly lower performance for other common aneuploidies. These tests have rapidly captured an increasing market share, with substantial reductions in the number of chorionic villus sampling and amniocentesis performed suggesting that physicians and patients regard such screening approaches as an equivalent replacement for diagnostic testing. Simultaneously, many clinical programs have noted significant decreases in patient counseling. In 2012 the Eunice Kennedy Shriver National Institute of Child Health and Human Development funded a blinded comparison of karyotype with the emerging technology of array comparative genomic hybridization showing that in patients with a normal karyotype, 2.5% had a clinically relevant microdeletion or duplication identified. In pregnancies with an ultrasound-detected structural anomaly, 6% had an incremental finding, and of those with a normal scan, 1.6% had a copy number variant. For patients of any age with a normal ultrasound and karyotype, the chance of a pathogenic copy number variant is greater than 1%, similar to the age-related risk of aneuploidy in the fetus of a 38 year old. This risk is 4-fold higher than the risk of trisomy 21 in a woman younger than 30 years and 5- to 10-fold higher than the present accepted risk of a diagnostic procedure. Based on this, we contend that every patient, regardless of her age, be educated about these risks and offered the opportunity to have a diagnostic procedure with

  15. Rapid screening test for porphyria diagnosis using fluorescence spectroscopy

    Porphyrias are rare genetic metabolic disorders, which result from deficiencies of enzymes in the heme biosynthesis pathway. Depending on the enzyme defect, different types of porphyrins and heme precursors accumulate for the different porphyria diseases in erythrocytes, liver, blood plasma, urine and stool. Patients with acute hepatic porphyrias can suffer from acute neuropathic attacks, which can lead to death when undiagnosed, but show only unspecific clinical symptoms such as abdominal pain. Therefore, in addition to chromatographic methods, a rapid screening test is required to allow for immediate identification and treatment of these patients. In this study, fluorescence spectroscopic measurements were conducted on blood plasma and phantom material, mimicking the composition of blood plasma of porphyria patients. Hydrochloric acid was used to differentiate the occurring porphyrins (uroporphyrin-III and coproporphyrin-III) spectroscopically despite their initially overlapping excitation spectra. Plasma phantom mixtures were measured using dual wavelength excitation and the corresponding concentrations of uroporphyrin-III and coproporphyrin-III were determined. Additionally, three plasma samples of porphyria patients were examined and traces of coproporphyrin-III and uroporphyrin-III were identified. This study may therefore help to establish a rapid screening test method with spectroscopic differentiation of the occurring porphyrins, which consequently allows for the distinction of different porphyrias. This may be a valuable tool for clinical porphyria diagnosis and rapid or immediate treatment.

  16. Testing human hair for Cannabis. III. rapid screening procedure for the simultaneous identification of delta 9-tetrahydrocannabinol, cannabinol, and cannabidiol.

    delta 9-Tetrahydrocannabinol (THC), cannabidiol (CBD), and cannabinol (CBN) are three constituents of the 16 that can be currently isolated from some Cannabis spp plants. Their identification in decontaminated hair can indicate exposure to cannabis. In this study, we propose a rapid, simple, and direct (without derivatization) screening procedure for the simultaneous identification and quantitation of CBD, CBN, and THC in hair of chronic cannabis abusers. Hair samples were washed with methylene chloride, hydrolyzed with sodium hydroxide, extracted with n-hexane-ethyl acetate (9:1, v/v), evaporated to dryness, and injected directly on a gas chromatographic-mass spectrometric system operating in electron-impact mode. THC-d3 was used as the internal standard. Thirty hair samples were tested. CBD was detected 23 times, CBN was detected 22 times, and THC was detected five times. Concentrations ranged from 0.03 to 3.00 ng/mg (mean, 0.44 ng/mg), from 0.01 to 1.07 ng/mg (mean, 0.13 ng/mg), and from 0.1 to 0.29 ng/mg hair (mean, 0.15 ng/mg) for CBD, CBN, and THC, respectively. These results show that this new screening procedure is suitable for the detection of CBD and CBN in the hair of cannabis abusers. PMID:8837945

    Erythrocyte zinc protoporphyrin (ZPP) was measured in 102 women blood donors to evaluate its usefulness in screening for evolving iron deficiency anemia, a reason for the deferral of donors. The results were compared with serum ferritin determinations. Five women were deferred before their first donation and eight women were deferred after one or two donations. Women with increased ZPP values all had low serum ferritin concentrations, indicating iron-deficient erythropoiesis that was caused by iron depletion. The positive predictive value of an increased ZPP in predicting deferral of the donor after one or two donations was 75%, whereas a serum ferritin concentration < or = 12 microg/L predicted deferral in 26% of the donors. The results indicate that the ZPP test can be recommended as a feasible and inexpensive predonation test to determine a subset of donors with iron-deficient erythropoiesis at risk of developing iron deficiency anemia.

    The purpose of this study was to extend existing nuclear medicine techniques for the diagnosis of esophageal motor disorders. A standard homogeneous bolus of 99mtechnetium sulfur colloid in water was swallowed in the supine position under the collimator of a gamma camera linked to a microprocessor. Bolus transit was recorded at 0.4-s intervals, and the movie obtained was used to analyze transit in an objective manner. Ten normal volunteers and 30 subjects with dysphagia not related to mechanical obstruction were studied with this technique. Radionuclide transit studies detected a higher incidence of esophageal motor abnormality than manometry or radiology in the dysphagia group. In addition a definitive description of the functional problem was possible in most cases. Radionuclide transit is a safe noninvasive test and suitable as a screening test for esophageal motor disorders.

    Aim To present and evaluate a new screening protocol for amblyopia in preschool children. Methods Zagreb Amblyopia Preschool Screening (ZAPS) study protocol performed screening for amblyopia by near and distance visual acuity (VA) testing of 15 648 children aged 48-54 months attending kindergartens in the City of Zagreb County between September 2011 and June 2014 using Lea Symbols in lines test. If VA in either eye was >0.1 logMAR, the child was re-tested, if failed at re-test, the child was referred to comprehensive eye examination at the Eye Clinic. Results 78.04% of children passed the screening test. Estimated prevalence of amblyopia was 8.08%. Testability, sensitivity, and specificity of the ZAPS study protocol were 99.19%, 100.00%, and 96.68% respectively. Conclusion The ZAPS study used the most discriminative VA test with optotypes in lines as they do not underestimate amblyopia. The estimated prevalence of amblyopia was considerably higher than reported elsewhere. To the best of our knowledge, the ZAPS study protocol reached the highest sensitivity and specificity when evaluating diagnostic accuracy of VA tests for screening. The pass level defined at ≤0.1 logMAR for 4-year-old children, using Lea Symbols in lines missed no amblyopia cases, advocating that both near and distance VA testing should be performed when screening for amblyopia.

    This study aimed to determine and evaluate the diagnostic accuracy of visual screening tests for detecting vision loss in elderly. This study is defined as study of diagnostic performance. The diagnostic accuracy of 5 visual tests -near convergence point, near accommodation point, stereopsis, contrast sensibility and amsler grid—was evaluated by means of the ROC method (receiver operating characteristics curves), sensitivity, specificity, positive and negative likelihood ratios (LR+/LR-). Visual acuity was used as the reference standard. A sample of 44 elderly aged 76.7 years (±9.32), who were institutionalized, was collected. The curves of contrast sensitivity and stereopsis are the most accurate (area under the curves were 0.814-p = 0.001, C.I.95%[0.653;0.975]— and 0.713-p = 0.027, C.I.95%[0,540;0,887], respectively). The scores with the best diagnostic validity for the stereopsis test were 0.605 (sensitivity 0.87, specificity 0.54; LR+ 1.89, LR-0.24) and 0.610 (sensitivity 0.81, specificity 0.54; LR+ 1.75, LR-0.36). The scores with higher diagnostic validity for the contrast sensibility test were 0.530 (sensitivity 0.94, specificity 0.69; LR+ 3.04, LR-0.09). The contrast sensitivity and stereopsis test's proved to be clinically useful in detecting vision loss in the elderly.

Objectives: To assess the prevalence of abuse among community dwelling elderly and to identify the various risk factors. Materials and Methods: This community-based cross-sectional study was conducted in 10 randomly selected wards of Guwahati city. A total of 331 elderly (60 years and above) were interviewed. Abuse was screened by Hwalek-Sengstock Elder Abuse Screening Test (H-S EAST). Results: The study revealed 9.31% prevalence. Neglect was the most common type of abuse reported. Age, sex, socioeconomic status, living status, and functional status were found to be significantly associated with abuse. Conclusion: Abuse is prevalent among elderly population. PMID:26435603

  5. An efficient algorithm to perform multiple testing in epistasis screening

    PubMed Central

    2013-01-01

    Background Research in epistasis or gene-gene interaction detection for human complex traits has grown over the last few years. It has been marked by promising methodological developments, improved translation efforts of statistical epistasis to biological epistasis and attempts to integrate different omics information sources into the epistasis screening to enhance power. The quest for gene-gene interactions poses severe multiple-testing problems. In this context, the maxT algorithm is one technique to control the false-positive rate. However, the memory needed by this algorithm rises linearly with the amount of hypothesis tests. Gene-gene interaction studies will require a memory proportional to the squared number of SNPs. A genome-wide epistasis search would therefore require terabytes of memory. Hence, cache problems are likely to occur, increasing the computation time. In this work we present a new version of maxT, requiring an amount of memory independent from the number of genetic effects to be investigated. This algorithm was implemented in C++ in our epistasis screening software MBMDR-3.0.3. We evaluate the new implementation in terms of memory efficiency and speed using simulated data. The software is illustrated on real-life data for Crohn’s disease. Results In the case of a binary (affected/unaffected) trait, the parallel workflow of MBMDR-3.0.3 analyzes all gene-gene interactions with a dataset of 100,000 SNPs typed on 1000 individuals within 4 days and 9 hours, using 999 permutations of the trait to assess statistical significance, on a cluster composed of 10 blades, containing each four Quad-Core AMD Opteron(tm) Processor 2352 2.1 GHz. In the case of a continuous trait, a similar run takes 9 days. Our program found 14 SNP-SNP interactions with a multiple-testing corrected p-value of less than 0.05 on real-life Crohn’s disease (CD) data. Conclusions Our software is the first implementation of the MB-MDR methodology able to solve large-scale SNP

    This study tested experimentally whether the combination of a history of childhood abuse and confrontation with difficult infant temperament is associated with negative changes in parenting self-efficacy. First-time pregnant women (N = 243) participated in the Adult Attachment Interview, which was used to assess the occurrence of abuse by parents in childhood and unresolved representations, and completed a task asking them to respond to infant cries. Sixty of the 243 participants (25%) experienced childhood abuse, mostly physical or sexual. The task simulated infant temperamental difficulty by manipulating soothing success in order to reflect an easy-to-soothe (80% soothing success) and a difficult-to-soothe infant (20% soothing success). Both after baseline and after each of the two stimulus series women assessed their parenting self-efficacy. Women who reported childhood abuse did not differ from women who reported no childhood abuse in parenting self-efficacy at baseline or in response to the easy-to-soothe infant (relative to baseline), but decreased more in parenting self-efficacy following the difficult-to-soothe infant. Effects did not vary according to resolution of trauma. These findings suggest that in response to infant temperamental difficulty, women who experienced childhood abuse may more easily lose confidence in their parenting abilities, which underlines the importance of preparing at-risk women for the possible challenges that come along with parenthood.

    Child sexual abuse is associated with social anxiety, low self-esteem, and intimacy deficits. This, in combination with the core belief of a dangerous world, might suggest that child abusers are sexually attracted to submissiveness. The Implicit Association Test (IAT) was used to examine this hypothesis. Results indicated that child abusers have a stronger sexual preference for submissiveness than rapists, although there were no differences between child abusers and non-sexual offenders. Multinomial logistic regression analysis revealed that submissive-sexy associations have incremental value over child-sex associations in differentiating child abusers from other offenders. The predictive value of both implicit associations was explored by correlating IAT scores with measures for recidivism risk, aggression, and interpersonal anxiety. Child abusers with stronger child-sex associations reported higher levels of interpersonal anxiety and hostility. More research on implicit cognition in sex offenders is required for a better understanding of what these and similar implicit measures are exactly measuring and what role implicit cognition may play in sexual offending.

    We report the first portable upconversion nanoparticles (UCNPs)-based paper device for road-side field testing of cocaine. Upon the recognition of cocaine by two pieces of rationally designed aptamer fragments, the luminescence of UCNPs immobilized on the paper is quenched by Au nanoparticles (AuNPs), which indicates the cocaine concentration. This device can give quantitative results in a short time with high sensitivity using only a smartphone as the apparatus. Moreover, this device is applicable in human saliva samples, and it also can be used to monitor the cocaine content change in blood samples. The results of this work demonstrate the prospect of developing UCNPs-based paper devices for field testing of drug abuse. PMID:26786499

    In this paper, we describe a miniaturised image-based fluorescence detection system and demonstrate its viability as a highly sensitive tool for point-of-care-analysis of drugs of abuse in human sweat with a focus on monitor individuals for drugs of abuse. Investigations of miniaturised and low power optoelectronic configurations and methodologies for real-time image analysis were successfully carried out. The miniaturised fluorescence detection system was validated against a reference detection system under controlled laboratory conditions by analysing spiked sweat samples in dip stick and then strip with sample pad. As a result of the validation studies, a 1 ng mL-1 limit of detection of cocaine in sweat and full agreement of test results with the reference detection system can be reported. Results of the investigations open the way towards a detection system that integrates a hand-held fluorescence reader and a wearable skinpatch, and which can collect and in situ analyse sweat for the presence of cocaine at any point for up to tenths hours.

    The identification and characterization of oxygen-rich compatible materials enables full-flow, staged combustion designs. Although these oxygen-rich designs offer significant cost, performance, and reliability benefits over existing systems, they have never been used operationally by the United States. If these systems are to be realized, it is critical to understand the long-term oxidative stability in high-temperature, high-pressure, oxygen-rich combustion environments. A unique facility has been constructed at the NASA Lewis Research Center to conduct tests of small-scale rocket engine materials and subcomponents in an oxygen-rich combustion environment that closely approximates a full-scale rocket engine. Thus, a broad range of advanced materials and concepts can be screened in a timely manner and at a relatively low cost.

    testing program was developed in fiscal year (FY) 2012 describing in some detail the work needed to develop and qualify Cast Stone as a waste form for the solidification of Hanford LAW (Westsik et al. 2012). Included within Westsik et al. (2012) is a section on the near-term needs to address Tri-Party Agreement Milestone M-062-40ZZ. The objectives of the testing program to be conducted in FY 2013 and FY 2014 are to: • Determine an acceptable formulation for the LAW Cast Stone waste form. • Evaluate sources of dry materials for preparing the LAW Cast Stone. • Demonstrate the robustness of the Cast Stone waste form for a range of LAW compositions. • Demonstrate the robustness of the formulation for variability in the Cast Stone process. • Provide Cast Stone contaminant release data for PA and risk assessment evaluations. The first step in determining an acceptable formulation for the LAW Cast Stone waste form is to conduct screening tests to examine expected ranges in pretreated LAW composition, waste stream concentrations, dry-materials sources, and mix ratios of waste feed to dry blend. A statistically designed test matrix will be used to evaluate the effects of these key parameters on the properties of the Cast Stone as it is initially prepared and after curing. The second phase of testing will focus on selection of a baseline Cast Stone formulation for LAW and demonstrating that Cast Stone can meet expected waste form requirements for disposal in the IDF. It is expected that this testing will use the results of the screening tests to define a smaller suite of tests to refine the composition of the baseline Cast Stone formulation (e.g. waste concentration, water to dry mix ratio, waste loading).

    This study compared the relative sensitivity of five inexpensive, rapid toxicity tests to the sensitivity of five standard aquatic acute toxicity tests through literature review and testing. The rapid toxicity tests utilized organisms that require little culturing or handling prior to testing: a freshwater rotifer (Branchionus calyciflorus); brine shrimp (Artemia salina); lettuce (Lactuca sativa); and two microbial tests (Photobacterium phosphoreum--Microtox{reg_sign} test, and a mixture of bacterial species--the Polytox{reg_sign} test). Standard acute toxicity test species included water fleas (Daphnia magna and Ceriodaphnia dubia), green algae (Selenastrum capricornutum), fathead minnows (Pimephales promelas), and mysid shrimp (Mysidopsis bahia). Sensitivity comparisons between rapid and standard acute toxicity tests were based on LC50/EC50 data from 11 test chemicals. Individually, the lettuce and rotifer tests ranked most similar in sensitivity to the standard tests, while Microtox fell just outside the range of sensitivities represented by the group of standard acute toxicity tests. The brine shrimp and Polytox tests were one or more orders of magnitude different from the standard acute toxicity tests for most compounds. The lettuce, rotifer, and Microtox tests could be used as a battery for preliminary toxicity screening of chemicals. Further evaluation of complex real-world environmental samples is recommended.

    Medical examinations only insufficiently measure cognitive impairment in neurological and neurosurgical patients. Due to costs an personnel shortages, adequate neuropsychological test methods are typically bypassed. Indeed, the very size and methodological problems of current tests impede their application in clinical practice. To resolve this dissatisfying state of affairs, we have developed a standardized, scored form of initial neuropsychological examination. The Neuropsychological Screening Test (NST) comprises 45 items, is easy to handle, and can be conducted in 15-20 min. The NST measures psychic performance along functional parameters such as orientation in place and time, primary and secondary language, visuospatial ability, attention, and memory skills. We have assessed the validity and reliability of the NST in a prospective study. 129 neurosurgical patients (60% malignant or benign cerebral tumors, 21% vascular malformations with and without subarachnoid hemorrhage, 6% traumatic brain injury, 3% hydrocephalus, 10% others) and 52 control subjects were included in the study. The difference in average total NST-scores was highly significant for the two groups (t = -7.84, DF = 177.93, p < .001). In addition, two chronologically separate subsamples of NCH patients (N = 81) and controls (N = 35) were tested using the Mini-Mental State (MMS). The correlation between total NST-score and MMS results was r = .49 (p < .001). Cross-tabulation was used to set a cut-off score, by means of which 80% of the neurosurgical patients were identified as true positive and 74% of the controls as true negative. A 24-hour retest confirmed the NST as reliable to .85 (p < .001).(ABSTRACT TRUNCATED AT 250 WORDS) PMID:7887046

    Colonoscopy is the current gold standard for the diagnosis and treatment of colorectal neoplasms. Several gastroenterological and/or endoscopical societies recommend screening by colonoscopy in high risk patients for colorectal cancer whilst for average risk patients colonoscopy remains a valid option. In some countries screening colonoscopy is now covered by medical insurance. It is also the final common pathway of all colorectal cancer screening methods. This paper addresses the advantages and also limitations of colonoscopy as the first procedure for colorectal screening and emphasizes the importance of organized training and continuous assessment of competence of gastroenterologists and the necessity to have quality control audits of the endoscopy units.

    Calculated globulin (total protein – albumin) is usually tested as part of a liver function test profile in both primary and secondary care and determines the serum globulin concentration, of which immunoglobulins are a major component. The main use hitherto of calculated globulin is to detect paraproteins when the level is high. This study investigated the potential to use low levels of calculated globulin to detect antibody deficiency. Serum samples with calculated globulin cut-off < 18 g/l based on results of a pilot study were collected from nine hospitals in Wales over a 12-month period. Anonymized request information was obtained and the samples tested for immunoglobulin levels, serum electrophoresis and, if appropriate, immunofixation. A method comparison for albumin measurement using bromocresol green and bromocresol purple was undertaken. Eighty-nine per cent (737 of 826) samples had an immunoglobulin (Ig)G level of < 6 g/l using the bromocresol green methodology with a cut-off of < 18 g/l, and 56% (459) had an IgG of < 4 g/l. Patients with both secondary and primary antibody deficiency were discovered and serum electrophoresis and immunofixation showed that 1·2% (10) had previously undetected small paraproteins associated with immune-paresis. Using bromocresol purple, 74% of samples had an IgG of < 6 g/l using a cut-off of < 23 g/l. Screening using calculated globulin with defined cut-off values detects both primary and secondary antibody deficiency and new paraproteins associated with immune-paresis. It is cheap, widely available and under-utilized. Antibody-deficient patients have been discovered using information from calculated globulin values, shortening diagnostic delay and time to treatment with immunoglobulin replacement therapy.

    AIMS: To review the performance of the Venereal Diseases Research Laboratory (VDRL) test and the Treponema pallidum haemagglutination assay (TPHA) as a combined screen for syphilis to provide a baseline for assessing screening by anti-treponemal IGG EIA. METHODS: Between 1980 and 1987 all serum samples were screened by both VDRL and TPHA tests. The FTA-ABS test was also used in suspected early primary syphilis, or when one of the other tests was positive. A positive result in a screening test was confirmed by quantitative testing. From 1988 all specimens were screened with an enzyme immunoassay (Captia Syph G) as a single screening test. RESULTS: Of the 44 primary, 47 secondary, and 38 early latent cases of syphilis, the VDRL and TPHA detected 32 (73%) and 31 (71%) of the primary cases; the combination detected 37 (84%). All 85 cases of cases of secondary and early latent infection were reactive in the TPHA test, whereas the VDRL was reactive in only 68 (80%). EIA had a reported sensitivity of 82% for primary infection. CONCLUSIONS: EIA can be used as a single screening test for detecting early syphilis because its results are comparable with those of the combined VDRL and TPHA tests. The conventional VDRL test should not be used as a single screening test. PMID:1740512

    Oxidation protection for the Orbiter reinforced carbon-carbon (RCC consists of three components: silicon carbide coating, tetraethyl orthosilicate (TEOS) impregnated into the carbon substrate and a silicon based surface sealant (designated Type A). The Orbiter Type A sealant is being consumed each mission, which results in increased carbon-carbon substrate mass loss, which adversely impacts the mission life of the RCC components. In addition, the sealant loss in combination with launch pad contamination (salt deposit and zinc oxide) results in RCC pinholes. A sealant refurbishment schedule to maintain mission life and minimize affects of pin hole formation has been implemented in the Orbiter maintenance schedule. The objective of this investigation is to develop an advanced sealant system for the RCC that extends the refurbishment schedule by reducing sealant loss/pin hole formation and that can be applied to existing Orbiter RCC components. This paper presents the results of arc jet screening tests conducted on several sealants that are being considered for application to the Orbiter RCC.

    As medical and recreational use of cannabis, or marijuana, becomes more prevalent, law enforcement needs a tool to evaluate whether drivers are operating vehicles under the influence of cannabis, specifically the psychoactive substance, tetrahydrocannabinol (THC). However, the cutoff concentration of THC that causes impairment is still controversial, and current on-site screening tools are not sensitive enough to detect trace amounts of THC in oral fluids. Here we present a novel sensing platform that employs giant magnetoresistive (GMR) biosensors integrated with a portable reader system and smartphone to detect THC in saliva using competitive assays. With a simple saliva collection scheme, we have optimized the assay to measure THC in the range from 0 to 50 ng/mL, covering most cutoff values proposed in previous studies. This work facilitates on-site screening for THC and shows potential for testing of other small molecule drugs and analytes in point-of-care (POC) settings. PMID:27434697

    The authors examined antecedents of abusive supervision and the relative importance of interactional and procedural justice as mediators of the relationship between abusive supervision and the work outcomes of affective organizational commitment and individual- and organization-directed citizenship behaviors. Data were obtained from subordinate-supervisor dyads from a telecommunication company located in southeastern China. Results of moderated regression analysis revealed that authoritarian leadership style moderated the relationship between supervisors' perceptions of interactional justice and abusive supervision such that the relationship was stronger for supervisors high rather than low in authoritarian leadership style. In addition, results of structural equation modeling analysis revealed that subordinates' perceptions of interactional but not procedural justice fully mediated the relationship between abusive supervision and the work outcomes. Implications for future investigations of abusive supervision are discussed. PMID:17227160

Five hair samples were obtained for analysis comprising four groups of drugs of abuse as follows: opioids (6-monoacethylmorphine, morphine, codeine), amphetamine (amphetamine, methamphetamine, 3,4-methylendioxyamphetamine--MDA, 3,4-methylendioxymethamphetamine--MDMA, 3,4-methylendioxyethylamphetamine--MDEA), cocaine and metabolites (benzoiloecgonine, cocaethylene) and cannabinoids (D9-tetrahydrocannabinol --9-THC, cannabinol--CBN). Obtained results were evaluated positively in all groups of drugs which were the subject of examination. Liquid chromatography coupled with tandem mass spectrometry in chemical ionization under atmospheric pressure option (LC-APCI-MS-MS) and gas chromatography coupled with tandem mass spectrometry and electron-impact ionization mode (GC-EI-MS-MS) were applied for analysis of analytes.

    Stealth is an adulterant advertised as being undetectable by adulteration tests. It has been described as peroxidase and peroxide, which, when added to urine samples, are intended to prevent a positive drug test. Characterization of the effect of Stealth on urine samples and immunoassay results was undertaken to assist in detection of this adulterant. Stealth was added to a number of urine matrices, and various parameters were evaluated including pH, specific gravity, color, creatinine, chloride, urea, blood, glucose, and nitrite. Samples were spiked with THC acid metabolite, benzoylecgonine, morphine, secobarbital, PCP, amphetamine, and lysergic acid diethylamide (LSD) then tested by Roche OnLine and Microgenics CEDIA immunoassay reagents. Results of these analyses showed Stealth did not cause the urine sample to exceed any of the monitored parameters including those routinely used in drug-testing laboratories that would indicate adulteration of a sample. It did, however, cause samples positive for the marijuana metabolite (11-nor-delta9-tetrahydrocannibinol-9-carboxylic acid), LSD, and opiate (morphine) at 125-150% of cutoff to screen negative by immunoassay. Adulterating an authentic positive sample provided by a marijuana user caused that sample to screen negative using these immunoassay reagents as well. PMID:11550822

    A preponderance of clinical evidence supports a significant public health benefit for prostate-specific antigen (PSA)-based screening and early detection of prostate cancer in appropriately counseled and selected men. Population-based screening with PSA decreases prostate cancer mortality; however, because of relatively poor specificity, PSA-based screening may also increase the detection of clinically insignificant cancers that would otherwise never require treatment. Use of newer biomarkers that increase the specificity for prostate cancer detection may aid in risk stratification and the appropriate identification of men for prostate biopsy. The authors review the 4-kallikrein panel and 4K probability score. PMID:26614027

    A minority of child abuse cases is recognized by professionals, making the role of non-professional bystanders essential. The stages of change construct, as proposed by the Transtheoretical Model, may provide a useful approach to explain non-professional helping behavior. The objective of this study was to test the applicability of the stages of change construct by (i) assessing whether cognitive determinants distinguish between the stages, (ii) testing the predictive value of the stages for future helping behavior and (iii) examining the mediating role of the stages in the relation between previous and future helping behavior. Data of 126 adult non-professional bystanders were analyzed. Respondents were questioned by telephone or via an Internet questionnaire, at baseline and after a follow-up of about two months later. Attitude toward helping was significantly less positive in pre-contemplation than in the other stages, and self-efficacy expectations were significantly higher in preparation compared with the other stages. Moreover, baseline preparators were more likely to conduct future helping behavior than those in the two earlier stages. Finally, the stages of change mediated the relation between previous and future helping behavior. Initial support was found for the applicability of the stages of change construct for helping behavior by non-professional bystanders. PMID:16849390

    Urine as well as head and pubic hair samples from drug abusers were analysed for opiates, cocaine and its metabolites, amphetamines, methadone and cannabinoids. Urine immunoassay results and the results of hair tests by means of gas chromatography-mass spectrometry were compared to the self-reported data of the patients in an interview protocol. With regard to the study group, opiate abuse was claimed from the majority in self-reports (89%), followed by cannabinoids (55%), cocaine (38%), and methadone (32%). Except for opiates the comparison between self-reported drug use and urinalysis at admission showed a low correlation. In contrast to urinalysis, hair tests revealed consumption in more cases. There was also a good agreement between self-reports of patients taking part in an official methadone maintenance program and urine test results concerning methadone. However, hair test results demonstrated that methadone abuse in general was under-reported by people who did not participate in a substitution program. Comparing self-reports and the results of hair analyses drug use was dramatically under-reported, especially cocaine. Cocaine hair tests appeared to be highly sensitive and specific in identifying past cocaine use even in settings of negative urine tests. In contrast to cocaine, hair lacks sensitivity as a detection agent for cannabinoids and a proof of cannabis use by means of hair analysis should include the sensitive detection of the metabolite THC carboxylic acid in the lower picogram range.

  13. Is early detection of abused children possible?: a systematic review of the diagnostic accuracy of the identification of abused children

    PubMed Central

    2013-01-01

    Background Early detection of abused children could help decrease mortality and morbidity related to this major public health problem. Several authors have proposed tools to screen for child maltreatment. The aim of this systematic review was to examine the evidence on accuracy of tools proposed to identify abused children before their death and assess if any were adapted to screening. Methods We searched in PUBMED, PsycINFO, SCOPUS, FRANCIS and PASCAL for studies estimating diagnostic accuracy of tools identifying neglect, or physical, psychological or sexual abuse of children, published in English or French from 1961 to April 2012. We extracted selected information about study design, patient populations, assessment methods, and the accuracy parameters. Study quality was assessed using QUADAS criteria. Results A total of 2 280 articles were identified. Thirteen studies were selected, of which seven dealt with physical abuse, four with sexual abuse, one with emotional abuse, and one with any abuse and physical neglect. Study quality was low, even when not considering the lack of gold standard for detection of abused children. In 11 studies, instruments identified abused children only when they had clinical symptoms. Sensitivity of tests varied between 0.26 (95% confidence interval [0.17-0.36]) and 0.97 [0.84-1], and specificity between 0.51 [0.39-0.63] and 1 [0.95-1]. The sensitivity was greater than 90% only for three tests: the absence of scalp swelling to identify children victims of inflicted head injury; a decision tool to identify physically-abused children among those hospitalized in a Pediatric Intensive Care Unit; and a parental interview integrating twelve child symptoms to identify sexually-abused children. When the sensitivity was high, the specificity was always smaller than 90%. Conclusions In 2012, there is low-quality evidence on the accuracy of instruments for identifying abused children. Identified tools were not adapted to screening because of

    A coaxial test fixture and a pulsed power supply have been built to conduct high-current screening tests on candidate materials for contacts to be used in first wall connectors on fusion devices, particularly tokamaks. The fixture was operated with half-sine-wave pulses of less than or equal to 300 kA; it is designed for carrying currents of up to 600 kA for approximately 300 ms at a repetition rate of 1 pulse every 5 minutes. The fixture is built as a vacuum vessel and capable of testing specimens in an ambient temperature of 300/sup 0/C. Instrumentation is provided to measure the current pulse, contact voltage drop, contact pressure, the strain caused by contact pressure, and the operating temperature. The test fixture, its power supply and possible future upgrades are described.

    2016-01-01

    Clinical movement screening tests are gaining popularity as a means to determine injury risk and to implement training programs to prevent sport injury. While these screens are being used readily in the clinical field, it is only recently that some of these have started to gain attention from a research perspective. This limits applicability and poses questions to the validity, and in some cases the reliability, of the clinical movement tests as they relate to injury prediction, intervention, and prevention. This editorial will review the following clinical movement screening tests: Functional Movement Screen™, Star Excursion Balance Test, Y Balance Test, Drop Jump Screening Test, Landing Error Scoring System, and the Tuck Jump Analysis in regards to test administration, reliability, validity, factors that affect test performance, intervention programs, and usefulness for injury prediction. It is important to review the aforementioned factors for each of these clinical screening tests as this may help clinicians interpret the current body of literature. While each of these screening tests were developed by clinicians based on what appears to be clinical practice, this paper brings to light that this is a need for collaboration between clinicians and researchers to ensure validity of clinically meaningful tests so that they are used appropriately in future clinical practice. Further, this editorial may help to identify where the research is lacking and, thus, drive future research questions in regards to applicability and appropriateness of clinical movement screening tools.

    We explored the potential impact of HPV testing on women’s intentions to be screened for cervical cancer in a cohort of Canadian women. Participants aged 25-65 from an ongoing trial were sent a questionnaire to assess women’s intentions to be screened for cervical cancer with HPV testing instead of Pap smears and to be screened every 4 years or after 25 years of age. We created scales for attitudes about HPV testing, perceived behavioural control and direct and indirect subjective norms. Demographic data and scales that were significantly different (p<0.1) between women who intended to be screened with HPV and those who did not intend were included in a stepwise logistic regression model. Of the 2016 invitations emailed, 1538 were received, and 981 completed surveys for a response rate of 63% (981/1538). Eighty-four percent of women (826/981) responded that they intended to attend for HPV-based cervical cancer screening, which decreased to 54.2% when the screening interval was extended, and decreased further to 51.4% when screening start was delayed to age 25. Predictors of intentions to undergo screening were attitudes (OR 1.22; 95%CI 1.15, 1.30), indirect subjective norms (OR 1.02; 95%CI 1.01, 1.03) and perceived behavioural control (OR 1.16; 95% CI 1.10; 1.22). Intentions to be screened for cervical cancer with HPV testing decreased substantially when the screening interval was extended and screening started at age 25. Use of primary HPV testing may optimize the screening paradigm, but programs should ensure robust planning and education to mitigate any negative impact on screening attendance rates. PMID:23754203

    Objective This retrospective study of all women who accessed the 2006 Manitoba Pap Test Week clinics was designed to determine factors associated with inadequate cervical cancer screening and changes in cervical cancer screening behavior. Methods Data were acquired using the CervixCheck Manitoba registry and an ancillary database of demographic information collected from clinic attendees. Results The study included 1124 women. Of these, 53% (n = 598) were under-screened (no Pap test in the previous 2 years) prior to accessing the clinics. Logistic regression analyses demonstrated that older age (odds ratio [OR] = 1.02, 95% confidence interval [CI] 1.01–1.03), no doctor (OR = 1.4, 95% CI 1.05–1.54), and living in Canada < 1 year (OR = 5.5, 95% CI 2.73–11.12) were associated with being under-screened prior to accessing the Pap Test Week clinics. Thirty-seven percent (n = 223) of under-screened women demonstrated improved screening status subsequent to the 2006 Pap Test Week (had a subsequent Papanicolaou [Pap] test performed within 2 years) and these women were more likely to live in an urban setting (P = 0.003), be younger (P < 0.001), originate outside Canada (P = 0.006), have lived in Canada for less than 1 year (P = 0.006), and have had an abnormal Pap test result in 2006 (P < 0.001). Previously under-screened women were less likely to become adequately-screened subsequent to 2006 if they had a Pap test performed at a Pap Test Week clinic compared to having a Pap test performed elsewhere (37% versus 60%, P < 0.001). Conclusion This study identified a subset of under-screened women accessing Pap Test Week clinics whose screening status might be most modifiable. PMID:23596357

    A reliable bedside test for screening of visual field defects is a valuable tool in the examination of patients with a putative disease affecting the sensory visual pathways. Conventional methods such as Donders' confrontation method, counting fingers in the visual field periphery, of two-hand confrontation are not sufficiently sensitive to detect minor but nevertheless serious visual field defects. More sensitive methods requiring only simple tools are also described. In this study, a test card with four red squares surrounding a fixation target, a black dot, with a total test area of about 11 x 12.5 degrees at a distance of 30 cm, was designed for testing experience of red colour saturation in four quadrants, red square test. The Goldmann visual field was used as reference. 125 consecutive patients with pituitary adenoma (159 eyes), craniopharyngeoma (9 eyes), meningeoma (21 eyes), vascular hemisphere lesion (40 eyes), hemisphere tumour (10 eyes) and hemisphere abscess (2 eyes) were examined. The Goldmann visual field and red square test were pathological in pituitary adenomas in 35%, in craniopharyngeomas in 44%, in meningeomas in 52% and in hemisphere tumours or abscess in 100% of the eyes. Among these, no false-normal or false-pathological tests were found. However, in vascular hemisphere disease the corresponding figures were Goldmann visual field 90% and red square test 85%. The 5% difference (4 eyes) was due to Goldmann visual field defects strictly peripheral to the central 15 degrees. These defects were easily diagnosed with two-hand confrontation and PMID:7747575

    1. A simple quantitative test has been developed to investigate phagocyte function. 2. This test is performed by the addition of Nitroblue Tetrazolium to whole blood, followed by the isolation of leucocytes on a column of nylon wool. Dye reduction by phagocytes is apparent as a blue coloration of the column due to the formation of formazan. The formazan can be extracted from the column and measured spectrophotometrically. 3. The formation of formazan was found to be directly related to the number of phagocytes in blood. 4. Two patients with chronic granulomatous disease gave abnormal results, suggesting that the test procedure may be of value as a screening procedure for this disease. PMID:1106938

    2009-01-01

    Although prior research has established that childhood abuse adversely affects midlife physical health outcomes, it is unclear how abuse continues to harm health decades after the abuse has ended. In this project, I assess four life course pathways (behavioral, emotional, cognitive, and social relations) that plausibly link childhood physical abuse to three midlife physical health outcomes (bronchitis diagnosis, ulcer diagnosis, and general physical health). These three outcomes are etiologically distinct, leading to unique testable hypotheses. Multivariate models controlling for childhood background and early adversity were estimated using data from over 3,000 respondents in the Wisconsin Longitudinal Study, USA. The results indicate that midlife social relations and cognition do not function as pathways for any outcome. However, smoking is a crucial pathway connecting childhood abuse with bronchitis; mental health is important for ulcers; and BMI, smoking, and mental health are paramount for general physical health. These findings suggest that abuse survivors’ coping mechanisms can lead to an array of midlife health problems. Furthermore, the results validate the use of etiologically distinct outcomes for understanding plausible causal pathways when using cross-sectional data. PMID:19446943

    Objective: To develop and evaluate a physiologic screening test specifically designed for collegiate female athletes engaged in athletic competition or highly athletic performances in order to detect eating disorders/disordered eating. No such physiologically based test currently exists. Methods: Subjects included 148 (84.5%) of 175 volunteer, National Collegiate Athletic Association Division I (n = 92), club (n = 15), and dance team (n = 41) athletes 18 to 25 years old who attended a large, Midwestern university. Participants completed 4 tests: 2 normed for the general population (Eating Disorders Inventory-2 and Bulimia Test-Revised); a new physiologic test, developed and pilot tested by the investigators, called the Physiologic Screening Test; and the Eating Disorder Exam 12.0D, a structured, validated, diagnostic interview used for criterion validity. Results: The 18-item Physiologic Screening Test produced the highest sensitivity (87%) and specificity (78%) and was superior to the Eating Disorders Inventory-2 (sensitivity = 62%, specificity = 74%) and Bulimia Test-Revised (sensitivity = 27%, specificity = 99%). A substantial number (n = 51, 35%) of athletes were classified as eating disordered/disordered eating. Conclusions: The Physiologic Screening Test should be considered for screening athletes for eating disorders/disordered eating. The Physiologic Screening Test seems to be a viable alternative to existing tests because it is specifically designed for female athletes, it is brief (4 measurements and 14 items), and validity is enhanced and response bias is lessened because the purpose is less obvious, especially when included as part of a mandatory preparticipation examination.

    Objective To determine the incremental costs and effects of different HPV testing strategies, when compared to Papanicolau cytology (Pap), for cervical cancer screening in Mexico. Methods A cost-effectiveness analysis (CEA) examined the specific costs and health outcomes associated with (1) no screening; (2) only the Pap test; (3) only self-administered HPV; (4) only clinician administered HPV; and (5) clinician administered HPV plus the Pap test. The costs of self- and clinician-HPV testing, as well as with the Pap test, were identified and quantified. Costs were reported in 2008 US dollars. The health outcome associated with these screening strategies was defined as the number of high-grade cervical intraepithelial neoplasia or cervical cancer cases detected. This CEA was performed using the perspective of the Mexican Institute of Social Security (IMSS) in Morelos, Mexico. Results Screening women between the ages of 30–80 for cervical cancer using clinical-HPV testing or the combination of clinical-HPV testing, and the Pap is always more cost-effective than using the Pap test alone. Conclusions This CEA indicates that HPV testing could be a cost-effective screening alternative for a large health delivery organization such as IMSS. These results may help policy-makers implement HPV testing as part of the IMSS cervical cancer screening program. PMID:21170578

    1977-01-01

    Continuing efforts to increase the versatility of the USF/NASA toxicity screening test method have included the use of different test conditions in order to simulate various fire environments. The use of air flow at flow rates of 16 to 48 ml/sec maintains oxygen concentrations above 19 percent throughout the 30 min exposure period, compared to above 16 percent without forced air flow. These levels of oxygen are well within the tolerance range of mice, and approach the oxygen levels found in many real fire situations. Proposed minimum oxygen levels based on experience with rats are unduly restrictive on the use of other species such as mice, and tend to eliminate the cost savings which may more than justify the selection of mice.

    A mass spectrometric method for drugs of abuse testing in exhaled breath employing a sampling device collecting aerosol particles was developed and applied in routine use. Analytes covered were amphetamine, methamphetamine, 6-acetylmorphine, morphine, cocaine, benzoylecgonine, diazepam, oxazepam and tetrahydrocannabinol. The method involved eluting drugs from the collection filter with methanol, quantification using deuterated analogs as internal standards, reversed phase chromatography with gradient elution, positive electrospray ionization and monitoring of two product ions per analyte in selected reaction monitoring mode. The measuring range was 6.0-1000pg/filter. The intra- and inter-assay imprecision expressed as the coefficient of variation was less than 7%. Influence from matrix was noted for most compounds but was compensated for the use of co-eluting internal standards. The LLOQ was 6.0pg/filter with intra-assay CV <5% and accuracy within 99-102% for all analytes. No chromatographic interference was observed in 20 negative control samples. The LC-MS/MS method was successfully applied for measuring drugs in unknown samples collected for the purpose of drug testing. Among the 1096 analyzed samples analytical findings were made in breath in 39 cases (3.6%). Most frequently found substances were the following: amphetamine (25 cases) methamphetamine (10 cases), THC (8 cases), cocaine (4 cases), benzoylecgonine (2 cases) and diazepam (2 cases). In conclusion, a fully validated and robust screening method suitable for the routine measurement of drugs of abuse in exhaled breath with a simple procedure for specimen collection and sample preparation was successfully developed.

    In a sample of 242 women in treatment for severe mental illness (SMI), we used regression analysis to test the hypothesis that lifetime physical and sexual abuse would correlate with self-harm behaviors (thoughts of self-harm and suicide, self-harming behaviors, and suicide attempts) when controlling for psychiatric symptoms, substance abuse, and negative appraisals of trauma. Lifetime physical abuse and alcohol use were the only significant factors in the model. Women with SMI should be screened regularly for physical abuse, alcohol use, as well as thoughts and behaviors related to self-harming behaviors. Limitations of the study include its cross-sectional design. PMID:26719079

    Atkinson, Joanna; Denmark, Tanya; Marshall, Jane; Mummery, Cath; Woll, Bencie

    2015-11-01

    To provide accurate diagnostic screening of deaf people who use signed communication, cognitive tests must be devised in signed languages with normative deaf samples. This article describes the development of the first screening test for the detection of cognitive impairment and dementia in deaf signers. The British Sign Language Cognitive Screening Test uses standardized video administration to screen cognition using signed, rather than spoken or written, instructions and a large norm-referenced sample of 226 deaf older people. Percentiles are provided for clinical comparison. The tests showed good reliability, content validity, and correlation with age, intellectual ability, and education. Clinical discrimination was shown between the normative sample and 14 deaf patients with dementia. This innovative testing approach transforms the ability to detect dementia in deaf people, avoids the difficulties of using an interpreter, and enables culturally and linguistically sensitive assessment of deaf signers, with international potential for adaptation into other signed languages.

    Berg, W.; Ko, K.

    1992-12-01

    A fluorescent screen was used to monitor relative beam position and spot size of a 56-MeV electron beam in the linac test stand. A chromium doped alumina ceramic screen inserted into the beam was monitored by a video camera. The resulting image was captured using a frame grabber and stored into memory. Reconstruction and analysis of the stored image was performed using PV-WAVE. This paper will discuss the hardware and software implementation of the fluorescent screen and imaging system. Proposed improvements for the APS linac fluorescent screens and image processing will also be discussed.

    Marrazzo, J M; Koutsky, L A; Kiviat, N B; Kuypers, J M; Stine, K

    2001-01-01

    OBJECTIVES: The purpose of this study was to examine frequency of and attitudes toward Papanicolaou (Pap) test screening in women who have sex with women (WSW) and to determine prevalence of genital human papillomavirus (HPV). METHODS: Women were eligible if they reported having engaged in sex with another woman in the preceding year Medical and sexual histories were obtained. Cervical specimens for Pap tests and cervical and vaginal specimens for HPV DNA testing were collected. RESULTS: HPV DNA was detected in 31 of 248 WSW (13%). Women who had never had sex with men were less likely to have undergone pelvic examinations and had fewer recent Pap tests. Reasons for not undergoing Pap tests included lack of insurance, previous adverse experiences, and belief that Pap tests were unnecessary. CONCLUSIONS: Despite the occurrence of genital HPV, WSW do not receive adequate Pap test screening. Pap test screening recommendations should not differ for WSW, regardless of sexual history with men. PMID:11392939

  8. The sexual abuse questionnaire: a preliminary examination of a time and cost efficient method in evaluating the presence of childhood sexual abuse in adult patients.

    2005-01-01

    This paper provides the results of two studies designed to evaluate a newly constructed self-report instrument, the Sexual Abuse Questionnaire (SAQ). The SAQ was designed as a brief screening device to aid in the identification of a childhood sexual abuse history. A "unique" feature of the SAQ is the inclusion of a number of non-face valid questions derived from clinical experience. Both studies used an undergraduate population of self-reported abused and non-abused participants. Based upon the combined results of the two studies, the final version of the SAQ was developed, which is comprised of 45 items that manifest good test-retest reliability, internal consistency, and convergent and discriminative validity. The SAQ can discriminate between abused and non-abused male and female participants. PMID:15914402

    Although radon exposure has been identified as the second leading cause of lung cancer, fewer than 6% of US homeowners test their homes for radon. This report examines participants' follow-up radon testing behavior subsequent to receiving an initial screening radon level greater than 20 pCi/L. Sixty-two participants in the Iowa State-Wide Rural Radon Screening Survey who had radon screening measurements over 20 pCi/L were questioned by phone survey 3 months after receipt of their radon screening result to assess: whether participants were aware of radon's health risk; if participants recalled the radon screening results; how participants perceived the relative health risk of radon and whether participants planned follow-up radon testing. Only 19% of the respondents specifically identified lung cancer as the possible adverse health outcome of high radon exposure, and the majority of participants underestimated the health risks high radon levels pose when compared to cigarettes and x-rays. In addition, less than one third (29%) of the participants actually remembered their radon screening level within 10 pCi/L 3 months after receiving their screening results. Only 53% of the individuals correctly interpreted their screening radon level as being in the high range, and only 39% of the participants planned follow-up radon measurements. Receipt of radon screening test results indicating high radon levels was not an adequate motivational factor in itself to stimulate further radon assessment or mitigation. The findings suggest that free radon screening will not result in a dramatic increase in subsequent homeowner initiated remediation or further recommended radon testing. 13 refs., 1 fig., 5 tabs.

    OBJECTIVE To provide estimates of physical abuse and use of health services among depressed women in order to inform efforts to increase detection and treatment of physical abuse. DESIGN Retrospective assessment of abuse and health services use over 1 year in a cohort of depressed women. SETTING Statewide community sample from Arkansas. PARTICIPANTS We recruited 303 depressed women through random-digit-dial screening. MEASUREMENTS AND MAIN RESULTS Exposure to physical abuse based on the Conflict Tactics Scale, multi-informant estimate of health and mental health services. Over half of the depressed women (55.2%) reported experiencing physical abuse as adults, with 14.5% reporting abuse during the study year. Women abused as adults had significantly more severe depressive symptoms, more psychiatric comorbidity, and more physical illnesses than nonabused women. After controlling for sociodemographic and severity-of-illness factors, recently abused, depressed women were much less likely to receive outpatient care for mental health problems as compared to other depressed women (odds ratio [OR] 0.3;p = .013), though they were more likely to receive health care for physical problems (OR 5.7, p = .021). CONCLUSIONS Because nearly all depressed women experiencing abuse sought general medical rather than mental health care during the year of the study, primary care screening for physical abuse appears to be a critical link to professional help for abused, depressed women. Research is needed to inform primary care guidelines about methods for detecting abuse in depressed women. PMID:9754516

    We prospectively examined whether first trimester nuchal translucency (NT) and second trimester triple test (TT) results are correlated, and determined overlapping and mutual screen-positive rates. Results of NT, TT, amniocentesis and pregnancy outcome were obtained in 508 normal pregnancies. Inter-test correlation was performed by comparing the likelihood ratios (LR). Overlapping of screen-positive cases, of NT and TT, was determined by comparing mutual risks for Down syndrome (DS) livebirth of > or = 1:380. Combined screen-positive rates were evaluated by using summation risk (NT and/or TT exhibiting a risk > or = 1:380) and calculated risk (new risk > or / =1:380, based on multiplication of LR(NT) and LR(TT)). Screen-positive rates between NT and TT differed significantly and when either test showed an increased risk for DS, the probability of the other to predict the same was negligible (p<0.001). Overall screen-positive rates, at a risk > or = 1:380, were 2% and 5.7% for NT and TT, respectively. Summation and calculated combining methods were associated with 7.5% and 2.0% screen-positive rates, respectively. Amniocentesis was performed on 20.7% of the cases, mostly screen-negative ones. Our results showed that, in normal pregnancies, NT and TT do not correlate and that their combined calculated risk in normal pregnancies is associated with a low screen-positive rate of 2.0%.

    Mersy, David J

    2003-04-01

    Ten percent of the population abuses drugs or alcohol, and 20 percent of patients seen by family physicians have substance-abuse problems, excluding tobacco use. These patients can be identified by relying on regular screening or a high index of suspicion based on "red flags" that can be noted in various clinical situations. The modified CAGE questionnaire is an excellent screening instrument, but several alternatives are available. The best screening test is one that the physician will routinely use well. Laboratory indicators such as gamma-glutamyl transpeptidase, mean corpuscular volume, and carbohydrate-deficient transferrin are nonspecific but can add to the evidence of alcohol abuse. If problem alcohol use is diagnosed, even brief physician advice can be helpful. If the problem has progressed to addiction, referral to an addiction specialist or treatment center is recommended. Special issues arise in dealing with substance abuse in adolescents, elderly patients, and patients with mental illness, but the family physician can play an important role in recognizing this common problem.

    PubMed

    Jagerdeo, Eshwar; Schaff, Jason E

    2016-08-01

    We present a UPLC(®)-High Resolution Mass Spectrometric method to simultaneously screen for nineteen benzodiazepines, twelve opiates, cocaine and three metabolites, and three "Z-drug" hypnotic sedatives in both blood and urine specimens. Sample processing consists of a high-speed, high-temperature enzymatic hydrolysis for urine samples followed by a rapid supported liquid extraction (SLE). The combination of ultra-high resolution chromatography with high resolution mass spectrometry allows all 38 analytes to be uniquely detected with a ten minute analytical run. Limits of detection for all target analytes are 3ng/mL or better, with only 0.3mL of specimen used for analysis. The combination of low sample volume with fast processing and analysis makes this method a suitable replacement for immunoassay screening of the targeted drug classes, while providing far superior specificity and better limits of detection than can routinely be obtained by immunoassay.

    Well established theory can be used to combine single-phenomenology hypothesis tests into a multi-phenomenology event screening hypothesis test (Fisher's and Tippett's tests). Commonly used standard error in Ms:mb event screening hypothesis test is not fully consistent with physical basis. Improved standard error - Better agreement with physical basis, and correctly partitions error to include Model Error as a component of variance, correctly reduces station noise variance through network averaging. For 2009 DPRK test - Commonly used standard error 'rejects' H0 even with better scaling slope ({beta} = 1, Selby et al.), improved standard error 'fails to rejects' H0.

    1996-12-31

    A new screening method for fuel contamination in soils was recently developed as American Society for Testing and Materials (ASTM) Method D-5831-95, Standard Test Method for Screening Fuels in Soils. This method uses low-toxicity chemicals and can be sued to screen organic- rich soils, as well as being fast, easy, and inexpensive to perform. Fuels containing aromatic compounds, such as diesel fuel and gasoline, as well as other aromatic-containing hydrocarbon materials, such as motor oil, crude oil, and cola oil, can be determined. The screening method for fuels in soils was evaluated by conducting a Collaborative study on the method. In the Collaborative study, a sand and an organic soil spiked with various concentrations of diesel fuel were tested. Data from the Collaborative study were used to determine the reproducibility (between participants) and repeatability (within participants) precision of the method for screening the test materials. The Collaborative study data also provide information on the performance of portable field equipment (patent pending) versus laboratory equipment for performing the screening method and a comparison of diesel concentration values determined using the screening method versus a laboratory method.

    2015-01-01

    This paper contains a joint ESHG/ASHG position document with recommendations regarding responsible innovation in prenatal screening with non-invasive prenatal testing (NIPT). By virtue of its greater accuracy and safety with respect to prenatal screening for common autosomal aneuploidies, NIPT has the potential of helping the practice better achieve its aim of facilitating autonomous reproductive choices, provided that balanced pretest information and non-directive counseling are available as part of the screening offer. Depending on the health-care setting, different scenarios for NIPT-based screening for common autosomal aneuploidies are possible. The trade-offs involved in these scenarios should be assessed in light of the aim of screening, the balance of benefits and burdens for pregnant women and their partners and considerations of cost-effectiveness and justice. With improving screening technologies and decreasing costs of sequencing and analysis, it will become possible in the near future to significantly expand the scope of prenatal screening beyond common autosomal aneuploidies. Commercial providers have already begun expanding their tests to include sex-chromosomal abnormalities and microdeletions. However, multiple false positives may undermine the main achievement of NIPT in the context of prenatal screening: the significant reduction of the invasive testing rate. This document argues for a cautious expansion of the scope of prenatal screening to serious congenital and childhood disorders, only following sound validation studies and a comprehensive evaluation of all relevant aspects. A further core message of this document is that in countries where prenatal screening is offered as a public health programme, governments and public health authorities should adopt an active role to ensure the responsible innovation of prenatal screening on the basis of ethical principles.

    2015-05-01

    Men who have sex with men (MSM) have higher rates of poor sexual health. The National Institute for Health and Care Excellence has produced guidance on increasing the uptake of HIV testing to reduce undiagnosed infection in MSM. We report the results of a pilot outreach sexually transmitted infection service using nurse-delivered screening and self-sampled postal testing at a sex on premises venue with comparison made against a sexual health clinic service. Thirty men were included in each group. Users of the nurse-delivered and postal services were older (nurse service median age 57.5 years vs. postal kit service 47 years vs. clinic 35.5 years, p ≤ 0.001). Outreach groups were less likely to have undertaken sexually transmitted infection testing previously than the clinic group (53.3% and 60% vs. 93.3%, p ≤ 0.001). Chlamydia trachomatis and Neisseria gonorrhoeae testing uptake was comparable across groups (nurse outreach 86.6%, 'do it yourself' postal kit 100% vs. clinic 100%, p = 0.032), but uptake for blood tests was lower in the postal kit group (nurse outreach 83.3%, postal kit 53.3% vs. clinic 100%, p ≤ 0.001). No significant difference in active sexually transmitted infection positivity across the groups was observed. This combination outreach screening approach is effective in targeting MSM who use sex on premises venues. PMID:24912535

  10. Newborn screening for citrin deficiency and carnitine uptake defect using second-tier molecular tests

    PubMed Central

    2013-01-01

    Background Tandem mass spectrometry (MS/MS) analysis is a powerful tool for newborn screening, and many rare inborn errors of metabolism are currently screened using MS/MS. However, the sensitivity of MS/MS screening for several inborn errors, including citrin deficiency (screened by citrulline level) and carnitine uptake defect (CUD, screened by free carnitine level), is not satisfactory. This study was conducted to determine whether a second-tier molecular test could improve the sensitivity of citrin deficiency and CUD detection without increasing the false-positive rate. Methods Three mutations in the SLC25A13 gene (for citrin deficiency) and one mutation in the SLC22A5 gene (for CUD) were analyzed in newborns who demonstrated an inconclusive primary screening result (with levels between the screening and diagnostic cutoffs). Results The results revealed that 314 of 46 699 newborns received a second-tier test for citrin deficiency, and two patients were identified; 206 of 30 237 newborns received a second-tier testing for CUD, and one patient was identified. No patients were identified using the diagnostic cutoffs. Although the incidences for citrin deficiency (1:23 350) and CUD (1:30 000) detected by screening are still lower than the incidences calculated from the mutation carrier rates, the second-tier molecular test increases the sensitivity of newborn screening for citrin deficiency and CUD without increasing the false-positive rate. Conclusions Utilizing a molecular second-tier test for citrin deficiency and carnitine transporter deficiency is feasible. PMID:23394329

  11. Cervical cancer screening of HPV vaccinated populations: Cytology, molecular testing, both or none.

    Cervical cancer control includes primary prevention through vaccination to prevent human papillomavirus (HPV) infection and secondary prevention through screening to detect and treat cervical precancerous lesions. This review summarizes the evidence for the population impact of vaccines against oncogenic HPV types in reducing the prevalence of cervical precancerous lesions. We examine the gradual shift in screening technology from cervical cytology alone to cytology and HPV cotesting, and finally to the recognition that HPV testing can serve alone as the new screening paradigm, particularly in the initial post-vaccination era. We should expect an impact on screening performance and practices, as cohorts of HPV-vaccinated girls and adolescents reach cervical cancer screening age. In preparation for changes in the screening paradigm for the vaccination era, we propose that policymaking on cervical cancer screening should mirror current practices with other cancers as benchmarks. Cervical precancerous lesions will become a very rare condition following the widespread implementation of HPV vaccines with broader coverage in the number of preventable oncogenic types. Irrespective of screening technology, the false positive results will far outnumber the true positive ones, a tipping point that will herald a new period when the harms from cervical cancer screening will outweigh its benefits. We present a conceptual framework to guide decision making when we reach this point within 25-30 years. PMID:26631958

    By the use of a one-step immunoassay drug test for oral fluid, a convenient and fairly sensitive screening method has been devised for methamphetamine (MA), 3,4-methylenedioxymethamphetamine (MDMA), and 3,4-methylenedioxyethylamphetamine (MDEA) incorporated in hair. These drugs, in a 10-mg portion of hair, were extracted into 5M HCl/methanol (1:20, v/v), and the extract reconstituted in 100 micro L water was assayed with the saliva drug test ORAL.screen trade mark. The limits of detection were 0.5 ng/mg hair for d-MA, 0.8 ng/mg for dl-MDMA, and 1.0 ng/mg for dl-MDEA. The results are in good agreement with those of gas chromatography-mass spectrometry (GC-MS) determination. Although all positive results must be confirmed by either GC-MS or a specific alternative methodology, this method provided a simple screening, suitable for drug enforcement purposes, while requiring only a 10-mg hair specimen.

    For the first time in Europe hair and urine testing have been applied to assess drugs of abuse consumption in couples undergoing assisted reproductive technology and the eventual association of toxic habits with other lifestyle, health status and sociodemographic factors was also investigated. Couples attending five assisted reproduction centers in Rome were invited to join the study. When they presented at the Centre for the visit, they were asked to answer a structured questionnaire concerning sociodemographic characteristics and lifestyle habits, and at the same time to provide hair and urine samples. Hair and urine testing for drugs of abuse, urinary profile of principal endogenous steroids involved in fertility process (testosterone, epitestosterone, androsterone, etiocholanolone and dehydroepiandrosterone) and of alcohol and tobacco smoke biomarkers were performed with validated methodologies. Of the 594 enrolled individuals (297 couples), 352 (164 couples and 24 single individuals from the couple) completed the questionnaire and gave both hair and urine samples, apart from 3 bald men, who only gave urine samples. Urine testing showed an overall 4.8% (17 individuals) positivity to drugs of abuse: 4.2% to cannabinoids, 1.4% to cocaine and 0.85% to both drugs. Results of 4cm segment hair samples testing matched those from urine samples. Thus, taking together, results of urine and hair testing confirmed repeated use of cannabis, cocaine and both drugs in 3.7, 0.85 and 0.57% examined individuals, respectively. Drug consumers were in a statistically higher percentage active smokers and alcohol drinkers, less prone to physical activity and with a trend towards higher weight than non consumers. Finally, repeated drug consumption was associated with significant lower concentration of urinary testosterone in males and of urinary dehydroepiandrosterone in females. The findings of the present study confirm the suitability of urine testing to disclose recent drugs of

    Drug abuse of pregnant women is a growing problem. The effect of prenatal drug exposure may have devastating effect on development of the offsprings that may be long-term or even permanent. One of the most common drug abused by pregnant women is methamphetamine (MA), which is also the most frequently abused illicit drug in the Czech Republic. Our previous studies demonstrated that prenatal MA exposure alters behavior, cognition, pain and seizures in adult rats in sex-specific manner. Our most recent studies demonstrate that prenatal MA exposure makes adult rats more sensitive to acute injection of the same or related drugs than their controls. The aim of the present study was to examine the effect of prenatal MA exposure on drug-seeking behavior of adult male rats tested in the Conditioned place preference (CPP). Adult male rats were divided to: prenatally MA-exposed (5 mg/kg daily for the entire prenatal period), prenatally saline-exposed (1 ml/kg of physiological saline) and controls (without maternal injections). The following drugs were used in the CPP test in adulthood: MA (5 mg/kg), amphetamine (5 mg/kg), cocaine (5 and 10 mg/kg), morphine (5 mg/kg), MDMA (5 mg/kg) and THC (2 mg/kg). Our data demonstrated that prenatally MA-exposed rats displayed higher amphetamine-seeking behavior than both controls. MA as well as morphine induced drug-seeking behavior of adult male rats, however this effect did not differ based on the prenatal MA exposure. In contrast, prenatal MA exposure induced rather tolerance to cocaine than sensitization after the conditioning in the CPP. MDMA and THC did not induce significant effects. Even though the present data did not fully confirmed our hypotheses, future studies are planned to test the drug-seeking behavior also in self-administration test. PMID:23130898

    The evaluation of propulsion system test and flight performance data involves reviewing an extremely large volume of sensor data generated by each test. An automated system that screens large volumes of data and identifies propulsion system parameters which appear unusual or anomalous will increase the productivity of data analysis. Data analysts may then focus on a smaller subset of anomalous data for further evaluation of propulsion system tests. Such an automated data screening system would give NASA the benefit of a reduction in the manpower and time required to complete a propulsion system data evaluation. A phase 1 effort to develop a prototype data screening system is reported. Neural networks will detect anomalies based on nominal propulsion system data only. It appears that a reasonable goal for an operational system would be to screen out 95 pct. of the nominal data, leaving less than 5 pct. needing further analysis by human experts.

    The early detection of colorectal cancer with effective screening is essential for reduction of cancer-specific mortality. The addition of fecal DNA testing in the armamentarium of screening methods already in clinical use launches a new era in the noninvasive part of colorectal cancer screening and emanates from a large number of previous and ongoing clinical investigations and technological advancements. In this review, we discuss the molecular rational and most important genetic alterations hallmarking the early colorectal carcinogenesis process. Also, representative DNA targets-markers and key aspects of their testing at the clinical level in comparison or/and association with other screening methods are described. Finally, a critical view of the strengths and limitations of fecal DNA tests is provided, along with anticipated barriers and suggestions for further exploitation of their use. PMID:26483873

    Morphine sulfate misuse is essentially observed among regular heroin injectors. To our knowledge, primary addiction to morphine sulfate is exceptional, especially among young adolescents. A 13-year-old girl, with no history of addiction, was found dead with three empty blisters of Skenan(®) LP 30 mg at her side. Opiates were detected in biological fluids and hair by chromatographic methods. Blood analyses confirmed morphine overdose (free morphine: 428 ng/mL; total morphine: 584 ng/mL) and segmental hair analysis confirmed regular exposure over several months (maximum morphine concentration 250 pg/mg). Suspecting the victim's mother of recreational use of Skenan(®), the magistrate ordered analysis of her hair, with negative results. From an epidemiological viewpoint, this case of oral morphine sulfate abuse in an adolescent with no previous history suggests the emergence of a new trend of morphine sulfate consumption. From a toxicological viewpoint, it demonstrates the value of hair testing, which documented the victim's regular exposure and made an important contribution to the police investigation.

    High-throughput screening (HTS) is one of the newest techniques used in drug design and may be applied in biological and chemical sciences. This method, due to utilization of robots, detectors and software that regulate the whole process, enables a series of analyses of chemical compounds to be conducted in a short time and the affinity of biological structures which is often related to toxicity to be defined. Since 2008 we have implemented the automation of this technique and as a consequence, the possibility to examine 100,000 compounds per day. The HTS method is more frequently utilized in conjunction with analytical techniques such as NMR or coupled methods e.g., LC-MS/MS. Series of studies enable the establishment of the rate of affinity for targets or the level of toxicity. Moreover, researches are conducted concerning conjugation of nanoparticles with drugs and the determination of the toxicity of such structures. For these purposes there are frequently used cell lines. Due to the miniaturization of all systems, it is possible to examine the compound’s toxicity having only 1–3 mg of this compound. Determination of cytotoxicity in this way leads to a significant decrease in the expenditure and to a reduction in the length of the study. PMID:22312262

    Capture, coding and communication of newborn screening (NBS) information represent a challenge for public health laboratories, health departments, hospitals, and ambulatory care practices. An increasing number of conditions targeted for screening and the complexity of interpretation contribute to a growing need for integrated information-management strategies. This makes NBS an important test of tools and architecture for electronic health information exchange (HIE) in this convergence of individual patient care and population health activities. For this reason, the American Health Information Community undertook three tasks described in this paper. First, a newborn screening use case was established to facilitate standards harmonization for common terminology and interoperability specifications guiding HIE. Second, newborn screening coding and terminology were developed for integration into electronic HIE activities. Finally, clarification of privacy, security, and clinical laboratory regulatory requirements governing information exchange was provided, serving as a framework to establish pathways for improving screening program timeliness, effectiveness, and efficiency of quality patient care services.

    Although past research has identified psychological and behavioral consequences for adults who were abused as children, few studies have examined the incidence and consequences of childhood physical abuse among adult alcoholics. The purpose of this study was to assess the prevalence of a childhood history of physical abuse in adult male alcoholics and to determine what differences may exist in the psychological profile and patterns of alcohol abuse in abused and nonabused alcoholics. The study sample was comprised of 100 male alcoholic inpatients from the alcoholism treatment unit at a metropolitan Veterans Administration hospital. Subjects were administered a self-report devised by the authors to assess a history of childhood physical abuse, the Michigan Alcoholism Screening Test (MAST), the Severity of Alcohol Dependence Questionnaire (SADQ), and the Symptom Checklist-90-Revised (SCL-90-R). Findings indicated that approximately one-third of the alcoholics were physically abused as children. Abused alcoholics reported having more severe psychological symptoms and distress than their nonabused counterparts, although they did not differ on the onset, severity, or treatment history for alcohol dependency.

    During final development testing of the Space Shuttle Reaction Control Subsystem propellant tanks, a problem with pressure transients in the system was uncovered. Due to the nature of the tanks, performance tests to determine the impact of the transients on the expulsion efficiency of the tanks could not directly simulate the actual conditions which would be present in a low-gravity environment. However, by masking or covering various segments of the propellant acquisition device, a good simulation of a low-gravity environment was achieved in ground testing.

    This study investigated the cost-effectiveness between double and single Fecal Immunochemical Test(s) (FIT) in a mass CRC screening. A two-stage sequential screening was conducted. FIT was used as a primary screening test and recommended twice by an interval of one week at the first screening stage. We defined the first-time FIT as FIT1 and the second-time FIT as FIT2. If either FIT1 or FIT2 was positive (+), then a colonoscopy was recommended at the second stage. Costs were recorded and analyzed. A total of 24,419 participants completed either FIT1 or FIT2. The detection rate of advanced neoplasm was 19.2% among both FIT1+ and FIT2+, especially high among men with age ≥55 (27.4%). About 15.4% CRC, 18.9% advanced neoplasm, and 29.9% adenoma missed by FIT1 were detected by FIT2 alone. Average cost was $2,935 for double FITs and $2,121 for FIT1 to detect each CRC and $901 for double FITs and $680 for FIT1 to detect each advanced neoplasm. Double FITs are overall more cost-effective, having significantly higher positive and detection rates with an acceptable higher cost, than single FIT. Double FITs should be encouraged for the first screening in a mass CRC screening, especially in economically and medically underserved populations/areas/countries. PMID:27144171

    Of 7,028 disorders with suspected Mendelian inheritance, 1,139 are recessive and have an established molecular basis. Although individually uncommon, Mendelian diseases collectively account for ~20% of infant mortality and ~18% of pediatric hospitalizations. Molecular diagnostic testing is currently available for only ~300 recessive disorders. Preconception screening, together with genetic counseling of carriers, has resulted in remarkable declines in the incidence of several severe recessive diseases including Tay-Sachs disease and cystic fibrosis. However, extension of preconception screening and molecular diagnostic testing to most recessive disease genes has hitherto been impractical. Recently, we reported a preconception carrier screen / molecular diagnostic test for 448 recessive childhood diseases. The current status of this test is reviewed here. Currently, this reports analytical validity of the comprehensive carrier test. As the clinical validity and clinical utility in the contexts described is ascertained, this article will be updated.

    In 1990, CAST (classification of audiograms by sequential testing) was proposed and developed as an automated, innovative approach to screening infant hearing using a modified Bayesian method. The method generated a four-frequency audiogram in a minimal number of test trials using VRA (visual reinforcement audiometry) techniques. Computer simulations were used to explore the properties (efficiency and accuracy) of the paradigm. The current work is designed to further test the utility of the paradigm with human infants and young children. Accordingly, infants and children between 6 months and 2 years of age were screened for hearing loss. The algorithm's efficacy was studied with respect to validity and reliability. Validity was evaluated by comparing CAST results with tympanometric data and outcomes of staircase-based testing. Test-retest reliability was also assessed. Results indicate that CAST is a valid, efficient, reliable, and potentially cost-effective screening method. PMID:8318708

    2014-07-01

    Movement screens have been suggested as an appropriate tool to identify 'uncontrolled movement' within the human neuromusculoskeletal system. Movement screens test the Central Nervous System along with the muscular system, for their combined ability to successfully control low threshold forces, such as those affecting posture and alignment, or, high threshold forces, such as those requiring muscular strength to control. Further information such as the identification of an anatomical site and direction of a potential uncontrolled movement can be elicited by this type of testing. This paper describes a low threshold, movement screen test, designed to be part of a battery of tests, which when used as a whole, can identify injury risk or factors affecting performance limitations. The testing is suggested to be a suitable assessment tool for Pilates Teachers working in a rehabilitative environment. PMID:25042325

    Technological advances have led to the development of powerful yet portable tablet computers whose touch-screen resolutions now permit the presentation of targets small enough to test the limits of normal visual acuity. Such devices have become ubiquitous in daily life and are moving into the clinical space. However, in order to produce clinically valid tests, it is important to identify the limits imposed by the screen characteristics, such as resolution, brightness uniformity, contrast linearity and the effect of viewing angle. Previously we have conducted such tests on the iPad 3. Here we extend our investigations to 2 other devices and outline a protocol for calibrating such screens, using standardised methods to measure the gamma function, warm up time, screen uniformity and the effects of viewing angle and screen reflections. We demonstrate that all three devices manifest typical gamma functions for voltage and luminance with warm up times of approximately 15 minutes. However, there were differences in homogeneity and reflectance among the displays. We suggest practical means to optimise quality of display for vision testing including screen calibration.

    Screening with faecal occult blood test (FOBT) has been shown to be effective in reducing mortality from colorectal cancer. Tuscany was the first region in Italy in which a screening programme for colorectal cancer by FOBT was initiated region-wide. The aim of the paper was to describe organizational aspects, a quality control model and the results of this experience. From June 2000 to December 2001, 192583 subjects aged 50-70 were invited to undergo a 1-day immunochemical test without any dietary restriction. A total of 78505 subjects (41%) performed the screening test, of whom 4537 responders had a positive test result (5.8%). Among them, 1122 refused any form of assessment or underwent a colonoscopy outside the screening referral centres, with an overall assessment compliance of 75.3%. Malignancies were found in 193 patients and at least a high-risk adenomatous polyp in 692 patients. In about a quarter of the positive subjects who underwent assessment, cancer or high-risk adenoma was detected. In conclusion, data from this experience supported the feasibility of biennial colorectal screening programme by FOBT, particularly regarding invitation compliance and positivity rate. Further efforts are necessary to implement screening extension and to improve data collection. PMID:15075784

  1. The clinical utility of HPV DNA testing in cervical cancer screening strategies.

    PubMed

    Bhatla, Neerja; Moda, Nidhi

    2009-09-01

    Cervical cancer continues to be the commonest cause of death among women in developing countries, largely due to the failure to the inability to sustain effective cytology-based screening programs. While this burden may come down following implementation of the human papillomavirus (HPV) vaccine, screening will still be required. HPV DNA testing is a promising new technology for cervical cancer prevention and is the most reproducible of all cervical cancer screening tests. Presently, the two assays most widely used for the detection of genital types are the polymerase chain reaction (PCR) and Hybrid Capture 2 assays (hc2). Rapid, affordable tests are expected to be available soon. HPV DNA testing can be used in a variety of clinical scenarios that include primary screening in women older than 30 yr; as an adjunctive test to cytology; in the triage of women with an equivocal cytologic report, e.g., ASC-US; or for follow-up post-treatment for cervical intraepithelial neoplasia (CIN). HPV DNA testing can also be performed on self-collected samples, which allows screening in remote areas and also in women who refuse gynecologic examination. PMID:19901435

    A promising new and rapid toxicity screening test was developed, the concept and principles of which are presented. The method consists of visual observation of in vivo inhibition of an enzymatic process, using a fluorescent substrate. Juvenile Daphnia magna was exposed to a toxicant dilution series for 1 h, after which the substrate was added and the enzymatic inhibition was observed visually, using a long-wave UV light. The 1-h EC50 results of 11 pure compounds are presented and compared to the conventional 24- and 48-h Daphnia magna EC50s. All 1-h fluorescence EC50s were of the same order of magnitude and correlated very well with the 24- and 48-h EC50s. The sensitivity and reproducibility of this cost-effective screening test were compared to those of the Microtox[reg sign] test. The scope for application and the potential of this new rapid toxicity screening test are evaluated.

    Epidemiological studies of dementia often use two-stage designs because of the relatively low prevalence of the disease and the high cost of ascertaining a diagnosis. The first stage of a two-stage design assesses a large sample with a screening instrument. Then, the subjects are grouped according to their performance on the screening instrument, such as poor, intermediate and good performers. The second stage involves a more extensive diagnostic procedure, such as a clinical assessment, for a particular subset of the study sample selected from each of these groups. However, not all selected subjects have the clinical diagnosis because some subjects may refuse and others are unable to be clinically assessed. Thus, some subjects screened do not have a clinical diagnosis. Furthermore, whether a subject has a clinical diagnosis depends not only on the screening test result but also on other factors, and the sampling fractions for the diagnosis are unknown and have to be estimated. One of the goals in these studies is to assess the relative accuracies of two screening tests. Any analysis using only verified cases may result in verification bias. In this paper, we propose the use of two bootstrap methods to construct confidence intervals for the difference in the accuracies of two screening tests in the presence of verification bias. We illustrate the application of the proposed methods to a simulated data set from a real two-stage study of dementia that has motivated this research. PMID:10844728

    The goal of this study was to determine if the multiple marker screening test (maternal serum alpha-fetoprotein, unconjugated estriol, human chorionic gonadotrophin, and maternal age) detects fetal Turner syndrome or just cystic hygroma/hydrops. Multiple marker screening tests from 4 groups were compared: 1) Turner syndrome with hydrops/ hygroma group (n = 10) = fetuses with cystic hygroma/hydrops and a 45X karyotype, 2) Turner syndrome without hydrops/hygroma (n = 9) = sonographically unremarkable fetal Turner syndrome or Turner mosaic, 3) hydrops group (n = 8) = all cases of fetal cystic hygroma/hydrops excluding Turner syndrome, 4) sex chromosome aneuploidy group (n = 16) = other sonographically normal fetal sex chromosome aneuploidies. Positive screening tests (Down syndrome risk > or = 1:190 or MSAFP > or = 2.5 MOM) were found in 60% (6/10) of the Turner syndrome with hydrops/hygroma group, but only 11% (1/9) of the Turner syndrome without hydrops/hygroma group (P = .04). The incidence of positive screening tests in the Hydrops group was 75% (6/8), while it was only 12.5% (2/16) in the other sex chromosome aneuploidy group. We conclude that the multiple marker screening test identifies fetuses with cystic hygroma/hydrops, and may do so independently of the etiology of the hydrops. PMID:8796763

    Aim: To examine the relationship between sensitivity measured from the BREAST test-set and clinical performance. Background: Although the UK and Australia national breast screening programs have regarded PERFORMS and BREAST test-set strategies as possible methods of estimating readers' clinical efficacy, the relationship between test-set and real life performance results has never been satisfactorily understood. Methods: Forty-one radiologists from BreastScreen New South Wales participated in this study. Each reader interpreted a BREAST test-set which comprised sixty de-identified mammographic examinations sourced from the BreastScreen Digital Imaging Library. Spearman's rank correlation coefficient was used to compare the sensitivity measured from the BREAST test-set with screen readers' clinical audit data. Results: Results shown statistically significant positive moderate correlations between test-set sensitivity and each of the following metrics: rate of invasive cancer per 10 000 reads (r=0.495; p < 0.01); rate of small invasive cancer per 10 000 reads (r=0.546; p < 0.001); detection rate of all invasive cancers and DCIS per 10 000 reads (r=0.444; p < 0.01). Conclusion: Comparison between sensitivity measured from the BREAST test-set and real life detection rate demonstrated statistically significant positive moderate correlations which validated that such test-set strategies can reflect readers' clinical performance and be used as a quality assurance tool. The strength of correlation demonstrated in this study was higher than previously found by others.

    The new generation of sequencing platforms opens new horizons in the genetics field. It is possible to exhaustively assay all genetic variants in an individual and search for phenotypic associations. The whole genome sequencing approach, when applied to a large human sample like the San Antonio Family Study, detects a very large number (>25 million) of single nucleotide variants along with other more complex variants. The analytical challenges imposed by this number of variants are formidable, suggesting that methods are needed to reduce the overall number of statistical tests. In this study, we develop a single degree-of-freedom test of variants in a gene pathway employing a random effect model that uses an empirical pathway-specific genetic relationship matrix as the focal covariance kernel. The empirical pathway-specific genetic relationship uses all variants (or a chosen subset) from gene members of a given biological pathway. Using SOLAR's pedigree-based variance components modeling, which also allows for arbitrary fixed effects, such as principal components, to deal with latent population structure, we employ a likelihood ratio test of the pathway-specific genetic relationship matrix model. We examine all gene pathways in KEGG database gene pathways using our method in the first replicate of the Genetic Analysis Workshop 18 simulation of systolic blood pressure. Our random effect approach was able to detect true association signals in causal gene pathways. Those pathways could be easily be further dissected by the independent analysis of all markers.

    Objective Cervical cancer screening using the human papillomavirus (HPV) test and Pap test together (co-testing) is an option for average-risk women ≥30 years of age. With normal co-test results, screening intervals can be extended. The study objective is to assess primary care provider practices, beliefs, facilitators and barriers to using the co-test and extending screening intervals among low-income women. Method Data were collected from 98 providers in 15 Federally Qualified Health Center (FQHC) clinics in Illinois between August 2009 and March 2010 using a cross-sectional survey. Results 39% of providers reported using the co-test, and 25% would recommend a three-year screening interval for women with normal co-test results. Providers perceived greater encouragement for co-testing than for extending screening intervals with a normal co-test result. Barriers to extending screening intervals included concerns about patients not returning annually for other screening tests (77%), patient concerns about missing cancer (62%), and liability (52%). Conclusion Among FQHC providers in Illinois, few administered the co-test for screening and recommended appropriate intervals, possibly due to concerns over loss to follow-up and liability. Education regarding harms of too-frequent screening and false positives may be necessary to balance barriers to extending screening intervals. PMID:23628517

    Background For women at potentially increased risk for ovarian cancer, data regarding screening and risk reduction are limited. Previous studies have reported on the behaviors of BRCA mutation carriers, but less is known about the behaviors of non-BRCA carriers. We surveyed a large cohort of women after BRCA testing to identify the prevalence and posttest predictors of risk-reducing and screening interventions. Methods A median of 3.7 years after BRCA testing, 1447 women who received genetic counseling and BRCA testing at 2 hospital sites were surveyed, with a 77.6% response rate. We analyzed data from 1077 survey respondents. We performed univariate and multivariate logistic regression analyses to identify predictors of risk-reducing salpingo-oophorectomy (RRSO), screening transvaginal ultrasonography (TVUS), and screening serum cancer antigen 125 (CA-125). Results Among the respondents, 201 women (18.7%) received positive test results for a deleterious mutation, 103 women (9.6%) received true-negative results, and 773 women (71.8%) received uninformative results. Overall, 19.1% of eligible women underwent RRSO and 39.6% used screening procedures. A positive BRCA result predicted RRSO (odds ratio [OR], 28.1; 95% CI, 16.2-48.6), TVUS (9.5 [4.3-21.0]), and serum CA-125 (13.0 [5.5-29.0]). Similarly, a true-negative BRCA result reduced the OR for RRSO (0.1 [0.0-0.6]), TVUS (0.2 [0.1-0.5]), and serum CA-125 (0.3 [0.1-0.7]). Of the 71.8% of women who received uninformative results after BRCA testing, 12.3% subsequently underwent RRSO, 33.8% reported ever having undergone screening serum CA-125 since BRCA testing, and 37.3% reported ever having undergone screening TVUS since BRCA testing. Conclusions Results of BRCA testing strongly predict RRSO and ovarian cancer screening. Use of RRSO and ovarian screening was reported in a sizable percentage of non-BRCA carriers despite insufficient data to determine the effectiveness of these interventions. PMID:23247828

    Purpose The cloned enzyme donor immunoassay (CEDIA) for buprenorphine is applied for both urine drugs-of-abuse screening and compliance monitoring. Sensitivity, specificity, and optimal cutoff of this assay have differed between studies. This may indicate that cross-reactivity has to be taken into account during assay evaluation. We therefore investigated the performance of the CEDIA buprenorphine assay for use in our patient population and explored the impact of cross-reactivity on assay accuracy. Methods The CEDIA buprenorphine assay and high-performance liquid chromatography–tandem mass spectrometry were employed to analyze drugs-of-abuse in urine samples from a healthy drug-naïve male volunteer after intake of two tablets of a prescription drug containing 400 mg paracetamol +30 mg codeine phosphate, and in urine samples (n=2,272) from drug-addicted patients. Receiver operating characteristic analyses were performed to express the diagnostic accuracy of the CEDIA buprenorphine assay. Results CEDIA buprenorphine was positive in one urine sample from the drug-naïve person after intake of the prescription drug. Twenty-five (1.1%) of the patient urine samples were positive for buprenorphine by CEDIA, but negative by high-performance liquid chromatography–tandem mass spectrometry. Codeine, morphine, and their respective metabolites were prevalent in samples that were false positive for buprenorphine. The specificity of the CEDIA buprenorphine assay increased to 99.7% when the cutoff was increased from 5 ng/mL to 10 ng/mL. Conclusion Intake of a therapeutic dose of codeine can yield a false-positive CEDIA buprenorphine result. Additive effects from metabolites of codeine contribute to cross-reactivity in concentrations much lower than listed in the manufacturer’s cross-reactivity guide. Raising the cutoff from 5 ng/mL to 10 ng/mL increased the diagnostic accuracy. Clinicians should be informed about the risk of false-positive results with the CEDIA

    Abstract Background: Consensus United States cervical cancer screening guidelines recommend use of combination Pap plus human papillomavirus (HPV) testing for women aged 30 to 65 years. An HPV test was approved by the Food and Drug Administration in 2014 for primary cervical cancer screening in women age 25 years and older. Here, we present the results of clinical-economic comparisons of Pap plus HPV mRNA testing including genotyping for HPV 16/18 (co-testing) versus DNA-based primary HPV testing with HPV 16/18 genotyping and reflex cytology (HPV primary) for cervical cancer screening. Methods: A health state transition (Markov) model with 1-year cycling was developed using epidemiologic, clinical, and economic data from healthcare databases and published literature. A hypothetical cohort of one million women receiving triennial cervical cancer screening was simulated from ages 30 to 70 years. Screening strategies compared HPV primary to co-testing. Outcomes included total and incremental differences in costs, invasive cervical cancer (ICC) cases, ICC deaths, number of colposcopies, and quality-adjusted life years for cost-effectiveness calculations. Comprehensive sensitivity analyses were performed. Results: In a simulation cohort of one million 30-year-old women modeled up to age 70 years, the model predicted that screening with HPV primary testing instead of co-testing could lead to as many as 2,141 more ICC cases and 2,041 more ICC deaths. In the simulation, co-testing demonstrated a greater number of lifetime quality-adjusted life years (22,334) and yielded $39.0 million in savings compared with HPV primary, thereby conferring greater effectiveness at lower cost. Conclusions: Model results demonstrate that co-testing has the potential to provide improved clinical and economic outcomes when compared with HPV primary. While actual cost and outcome data are evaluated, these findings are relevant to U.S. healthcare payers and women's health policy advocates

    Human papilloma virus DNA testing may improve the cost effectiveness of cervical cancer screening programs. However, the circumstances to get this improvement are not the same between countries. The objective of this paper is to evaluate the cost effectiveness of introducing human papilloma virus testing in the current screening practice both in developed and developing countries. We conducted a review of published articles since January 2000 until December 2006 related to the cost effectiveness of introducing human papilloma virus testing in cervical cancer screening programs. A total of 17 original researches and six reviews were analyzed. Human papilloma virus testing is cost effective in developed countries only if it is a complementary test to Pap test and used to determine the management of women with atypical squamus cells of undetermined significance, the interval among tests is increased more than two years and it is performed in women over 30 years. On the other hand, developing countries should establish first organized screening programs and guarantee full coverage and access to diagnosis and treatment. PMID:18645671

    This paper presents experimental design and test results of the recently concluded 1-g inverted vertical outflow testing of two 325 × 2300 full scale liquid acquisition device (LAD) channels in liquid hydrogen (LH2). One of the channels had a perforated plate and internal cooling from a thermodynamic vent system (TVS) to enhance performance. The LADs were mounted in a tank to simulate 1-g outflow over a wide range of LH2 temperatures (20.3-24.2 K), pressures (100-350 kPa), and flow rates (0.010-0.055 kg/s). Results indicate that the breakdown point is dominated by liquid temperature, with a second order dependence on mass flow rate through the LAD. The best performance is always achieved in the coldest liquid states for both channels, consistent with bubble point theory. Higher flow rates cause the standard channel to break down relatively earlier than the TVS cooled channel. Both the internal TVS heat exchanger and subcooling the liquid in the propellant tank are shown to significantly improve LAD performance.

    1989-01-01

    A unique test chamber for exposing material to a known flux of oxygen atoms is described. The capabilities and operating parameters of the apparatus include production of an oxygen atom flux in excess of 5 x 10 to the 16th atoms/sq cm-sec, controlled heating of the sample specimen, RF circuitry to contain the plasma within a small volume, and long exposure times. Flux measurement capabilities include a calorimetric probe and a light titration system. Accuracy and limitations of these techniques are discussed. An extension to the main chamber to allow simultaneous ultraviolet and atomic oxygen exposure is discussed. The oxygen atoms produced are at thermal energies. Sample specimens are maintained at any selected temperature between ambient and 200 C, to within + or - 2 C. A representative example of measurements made using the chamber is presented.

    Pelvic rotation during cycling is important because it influences aerodynamics, cycling efficiency and the occurrence of overuse injuries. The aim of this study was to determine whether or not pelvic position in long sitting influences pelvic position during cycling. An observational, cross sectional, within-subjects study design was used. Thirty elite international track and road cyclists participated as subjects and two measures were undertaken. In long sitting, a digital inclinometer was positioned on the lumbosacral junction to give a static measure in degrees of sacral inclination (SI) relative to the horizontal. During active cycling, video analysis of reflective surface markers over the anterior superior iliac spine and posterior superior iliac spine was used to give a measure in degrees of anterior pelvic rotation (APR), by the angle between these two landmarks and the horizontal. No significant linear relationship was found between the two testing positions (r = 0.23, p = 0.22). PMID:16602164

    The objective of the study was to evaluate whether mental health problems identified through screens administered in first grade are related to poorer academic achievement test scores in the fourth grade. The government of Chile uses brief teacher- and parent-completed measures [Teacher Observation of Classroom Adaptation-Revised (TOCA-RR) and Pediatric Symptom Checklist (PSC-Cl)] to screen for mental health problems in about one-fifth of the country's elementary schools. In fourth grade, students take the national achievement tests (SIMCE) of language, mathematics and science. This study examined whether mental health problems identified through either or both screens predicted achievement test scores after controlling for student and family risk factors. A total of 17,252 students had complete first grade teacher forms and these were matched with fourth grade SIMCE data for 11,185 students, 7,903 of whom also had complete parent form data from the first grade. Students at risk on either the TOCA-RR or the PSC-Cl or both performed significantly worse on all SIMCE subtests. Even after controlling for covariates and adjusting for missing data, students with mental health problems on one screen in first grade had fourth grade achievement scores that were 14-18 points (~1/3 SD) lower than students screened as not at risk. Students at risk on both screens had scores that were on average 33 points lower than students at risk on either screen. Mental health problems in first grade were one of the strongest predictors of lower achievement test scores 3 years later, supporting the premise that for children mental health matters in the real world.

  11. An assessment of the NASA flammability screening test and related aspects of material flammability

    1992-08-01

    The results of an assessment of the NASA flammability screening test (8060.1B) for materials to be used in manned spacecraft interiors are summarized. A set of materials was examined using the standard NASA test, a modified version of this test which incorporated external radiation and National Institute of Standards and Technology (NIST) tests which measure ignitability, rate of heat release, and opposed flow flame spread behavior. Materials passing the standard NASA screening test showed widely varying degrees of flammability enhancement when subjected to external radiation (modified NASA test, NIST tests). Since such radiation is implicit in many normal fire scenarios, materials passing the standard NASA screening test should not be treated as non-flammable. The quantitative role of self-feedback of radiation remains to be fully clarified; an apparatus to examine this issue was built but no tests could be completed in the allotted time. The rate of heat release from the two-sided burning of thermally-thin materials was quantitatively compared to that for one-sided burning; this issue was believed to be at the heart of certain anomalies in the earlier stages of this study. A synergistic enhancement of heat release rate was indeed found for two-sided burning of three materials; two simplified models account for the origin of this effect. On the basis of this study, it is recommended that NASA supplement their existing flammability screening test with one that incorporates external radiation. It is further recommended that this supplemental test in normal gravity be correlated experimentally with a similar test in micro-gravity.

    Several screening tests for glucose 6 phosphate dehydrogenase (G6PD) deficiency have been reported thus far, and a standardized method of testing was proposed by the International Council for Standardization in Hematology (ICSH). The screening test used in any particular laboratory depends upon a number of factors such as cost, time required, temperature, humidity, and availability of reagents. In this study, a direct comparison between three different G6PD screening methods has been undertaken. In 71 cases (50 hematologically normal volunteers, 9 hemizygous G6PD-deficient males, and 12 heterozygous deficient females), the blue formazan spot test (BFST) was compared with the conventional methemoglobin reduction test (HiRT) and the ICSH-recommended fluorescent spot test (FST-ICSH). In all cases, the results obtained with the three screening tests were correlated with the enzyme activity assayed spectrophotometrically. In hemizygous G6PD-deficient males, all cases were equally detected with the three methods: BFST (4.7-6.64, controls: 11.1-13.4), BMRT (score +3 in all 9 cases), and FST (no fluorescence in 9 cases). In heterozygous G6PD-deficient females, two methods detected 7 out of 12 cases (BFST: 8.71-11.75, controls: 11.1-13.4; and BMRT: score +3 in 7 cases), whereas the FST-ICSH missed all 12 cases that presented a variable degree of fluorescence. Although the sensitivity for G6PD-deficient carrier detection is the same for the BMRT and the BFST, the latter has the advantage of being semiquantitative and not merely qualitative. Unfortunately, none of the three screening tests compared here allowed the detection of the 100% heterozygote carrier state of G6PD deficiency. PMID:10407579

  13. Good laboratory practices for biochemical genetic testing and newborn screening for inherited metabolic disorders.

    PubMed

    2012-04-01

    Biochemical genetic testing and newborn screening are essential laboratory services for the screening, detection, diagnosis, and monitoring of inborn errors of metabolism or inherited metabolic disorders. Under the Clinical Laboratory Improvement Amendments of 1988 (CLIA) regulations, laboratory testing is categorized on the basis of the level of testing complexity as either waived (i.e., from routine regulatory oversight) or nonwaived testing (which includes tests of moderate and high complexity). Laboratories that perform biochemical genetic testing are required by CLIA regulations to meet the general quality systems requirements for nonwaived testing and the personnel requirements for high-complexity testing. Laboratories that perform public health newborn screening are subject to the same CLIA regulations and applicable state requirements. As the number of inherited metabolic diseases that are included in state-based newborn screening programs continues to increase, ensuring the quality of performance and delivery of testing services remains a continuous challenge not only for public health laboratories and other newborn screening facilities but also for biochemical genetic testing laboratories. To help ensure the quality of laboratory testing, CDC collaborated with the Centers for Medicare & Medicaid Services, the Food and Drug Administration, the Health Resources and Services Administration, and the National Institutes of Health to develop guidelines for laboratories to meet CLIA requirements and apply additional quality assurance measures for these areas of genetic testing. This report provides recommendations for good laboratory practices that were developed based on recommendations from the Clinical Laboratory Improvement Advisory Committee, with additional input from the Secretary's Advisory Committee on Genetics, Health, and Society; the Secretary's Advisory Committee on Heritable Disorders in Newborns and Children; and representatives of newborn

    Background Automated Mediace Treponema pallidum latex agglutination (TPLA) and Mediace rapid plasma reagin (RPR) assays are used by many laboratories for syphilis diagnosis. This study compared the results of the traditional syphilis screening algorithm and a reverse algorithm using automated Mediace RPR or Mediace TPLA as first-line screening assays in subjects undergoing a health checkup. Methods Samples from 24,681 persons were included in this study. We routinely performed Mediace RPR and Mediace TPLA simultaneously. Results were analyzed according to both the traditional algorithm and reverse algorithm. Samples with discordant results on the reverse algorithm (e.g., positive Mediace TPLA, negative Mediace RPR) were tested with Treponema pallidum particle agglutination (TPPA). Results Among the 24,681 samples, 30 (0.1%) were found positive by traditional screening, and 190 (0.8%) by reverse screening. The identified syphilis rate and overall false-positive rate according to the traditional algorithm were lower than those according to the reverse algorithm (0.07% and 0.05% vs. 0.64% and 0.13%, respectively). A total of 173 discordant samples were tested with TPPA by using the reverse algorithm, of which 140 (80.9%) were TPPA positive. Conclusions Despite the increased false-positive results in populations with a low prevalence of syphilis, the reverse algorithm detected 140 samples with treponemal antibody that went undetected by the traditional algorithm. The reverse algorithm using Mediace TPLA as a screening test is more sensitive for the detection of syphilis. PMID:26522755

    A new screening test for optic nerve pathology is described, consisting of a series of four red targets presented at an angle of 12 degrees in the paracentral field above and below the horizontal meridian. Nonperception and desaturation of the targets are recorded. Inter-observer variability studies found a kappa value = 0.8. A total of 6831 individuals aged > or = 5 years in communities that were mesoendemic for savanna onchocerciasis in Kaduna State, northern Nigeria, were screened using the test. Of the participants 22% were unable to complete the test; almost two-thirds of these (62%) were aged 5-8 years. After exclusion of those visually impaired or blind according to WHO criteria and those unable to complete the test, the test showed a sensitivity of 40% and a specificity of 98% for optic nerve disease when inability to visualize one or more targets was used as the definition of test failure. The sensitivity increased to 54% with a specificity of 96% when the criterion for failure included desaturation of one or more targets. These values compare favourably with those for other available screening methods. The test took 1-2 minutes to perform and was readily accepted by patients and nurses. Images Fig. 1 PMID:9060216

    Objectives To assess the performance of a 5-type human papillomavirus (HPV) messenger RNA (mRNA) test in primary screening within the framework of the Norwegian population-based screening programme. Design Nationwide register-based cohort study. Setting In 2003–2004, general practitioners and gynaecologists recruited 18 852 women for participation in a primary screening study with a 5-type HPV mRNA test. Participants After excluding women with a history of abnormal smears and with cervical intraepithelial neoplasia grade 2 (CIN2+) before or until 3 months after screening, 11 220 women aged 25–69 years were eligible for study participation. The Norwegian Cancer Registry completed follow-up of CIN2+ through 31 December 2009. Interventions Follow-up according to the algorithm for cytology outcomes in the population-based Norwegian Cervical Cancer Screening Programme. Main outcome measures We estimated cumulative incidence of CIN grade 3 or worse (CIN3+) 72 months after the 5-type HPV mRNA test. Results 3.6% of the women were HPV mRNA-positive at baseline. The overall cumulative rate of CIN3+ was 1.3% (95% CI 1.1% to 1.5%) through 72 months of follow-up, 2.3% for women aged 25–33 years (n=3277) and 0.9% for women aged 34–69 years (n=7943). Cumulative CIN3+ rates by baseline status for HPV mRNA-positive and mRNA-negative women aged 25–33 years were 22.2% (95% CI 14.5% to 29.8%) and 0.9% (95% CI 0.4% to 1.4%), respectively, and 16.6% (95% CI 10.7% to 22.5%) and 0.5% (95% CI 0.4% to 0.7%), respectively, in women aged 34–69 years. Conclusions The present cumulative incidence of CIN3+ is similar to rates reported in screening studies via HPV DNA tests. Owing to differences in biological rationale and test characteristics, there is a trade-off between sensitivity and specificity that must be balanced when decisions on HPV tests in primary screening are taken. HPV mRNA testing may be used as primary screening for women aged 25–33 years and

    The slug test is the most widely used technique for the in situ estimation of hydraulic conductivity in confined and unconfined formations. Currently, there are no generally accepted methods in the groundwater literature for the analysis of response data from slug tests performed in wells screened across the watertable. A field study was undertaken in an attempt to develop a set of practical guidelines for tests conducted in such wells. Three wells, screened within unconsolidated material exhibiting a range of hydraulic conductivities (.05-30.0 m/day), were installed to depths of up to 9 m (30 ft) in Kansas River alluvium that ranges in thickness from 15 m to 21 m (50 ft to 70 ft) near Lawrence, Kansas. Intensive well-development efforts removed any drilling debris that could interfere with well-formation hydraulics. Once the wells were developed properly, a series of slug tests was performed at each well. The tests were designed to assess the role of the unsaturated zone and the appropriateness of assuming a fixed hydraulic head upper boundary. The results of this investigation can be summarized as follows: (1) the sufficiency of well development should be based on repeat slug tests and not the clarity of pumped water; (2) the effective screen radius for best model analysis should be based on a mass balance and not nominal screen dimensions; (3) the watertable can be represented as a constant head boundary and flow in the unsaturated zone can be ignored in most situations; (4) conventional techniques for the analysis of slug-test data seem to be reasonable for slug tests conducted in wells screened across the watertable, when used with the appropriate effective screen radius and normalized head range; and (5) fluctuations in the watertable elevation through time can be exploited to obtain some insight into the nature of vertical variation in hydraulic conductivity at a well. The results of this investigation indicate that multiple slug tests should be performed at

    The present study examined whether psychopathy can be understood as a constellation of traits from the Five Factor Model (FFM) of personality. Using a prototype matching approach, we examined the ability of the Revised NEO Personality Inventory (NEO PI-R; Costa & McCrae, 1992) to represent psychopathy in a sample of 297 male and female known crack cocaine abusers. Importantly, we examined the convergence and divergence between FFM psychopathy and other personality disorders assessed using the FFM. FFM psychopathy was correlated with self-reports of antisocial behavior, drug use, risky sex, and externalizing and internalizing disorder symptoms. As expected, there was overlap in the relations between psychopathy and several Cluster B personality disorders, but there were also important points of divergence. These results further extend the nomological network of FFM psychopathy and provide additional support for considering psychopathy a constellation of personality traits from a general model.

    The Internet Process Addiction Test (IPAT) was created to screen for potential addictive behaviors that could be facilitated by the internet. The IPAT was created with the mindset that the term “Internet addiction” is structurally problematic, as the Internet is simply the medium that one uses to access various addictive processes. The role of the internet in facilitating addictions, however, cannot be minimized. A new screening tool that effectively directed researchers and clinicians to the specific processes facilitated by the internet would therefore be useful. This study shows that the Internet Process Addiction Test (IPAT) demonstrates good validity and reliability. Four addictive processes were effectively screened for with the IPAT: Online video game playing, online social networking, online sexual activity, and web surfing. Implications for further research and limitations of the study are discussed. PMID:26226007

    This paper examines the effect of varying the liquid temperature and pressure on the bubble point pressure for screen channel Liquid Acquisition Devices in cryogenic liquid methane using gaseous helium across a wide range of elevated pressures and temperatures. Testing of a 325 x 2300 Dutch Twill screen sample was conducted in the Cryogenic Components Lab 7 facility at the NASA Glenn Research Center in Cleveland, Ohio. Test conditions ranged from 105 to 160K and 0.0965 - 1.78 MPa. Bubble point is shown to be a strong function of the liquid temperature and a weak function of the amount of subcooling at the LAD screen. The model predicts well for saturated liquid but under predicts the subcooled data.

  5. Down's syndrome screening: a controversial test, with more controversy to come!

    PubMed

    Reynolds, T M

    2000-12-01

    By 1998, most health authorities offered antenatal screening for Down's syndrome, usually by biochemical methods. To date, the development of this form of screening has not been coordinated by a national body and, consequently, there are wide variations in practice between localities. Fortunately, many of these variations have not led to any noticeable inequality of health provision, but the wide variation in risk cut offs used by different centres does. Other variations merely lead to potentially unnecessary expenditure; whereas it is believed that adding extra tests to the screening procedure is beneficial (such as double test to triple test), statistical evaluation of the confidence intervals for the detection rates quoted indicates that there is no evidence that the extra test provides an increase in detection. The cervical screening programme has progressively improved, partly through the auspices of a national framework. A similar national approach would benefit Down's screening and is only now being considered: the national screening committee (NSC) is currently drafting recommendations. To ensure optimum screening performance, the NSC should specify the risk thresholds applied, the screening protocols to be used--that is, an opt-in programme with a minimum (possibly even a maximum) of two biochemical analytes or a nuchal fold evaluation--and perhaps should even recommend national population parameters to be used for risk calculation. It might even be advisable for statistical work to be carried out to determine whether local derivation of medians is truly necessary. Furthermore, defined options for older women could be specified--for example, should all older patients have the option to proceed directly to amniocentesis if they wish or should National Health Service amniocentesis only be available for those with a "high risk" screening result. The difficulties that will face the NSC in deciding which screening policy to adopt are also considered

    Implementation of HIV testing has the objective to increase screening, identify and counsel persons with infection, link them to clinical services and reduce transmission. Rapid tests and/or alternative biological samples (like oral fluid) give the option for a better general consent in approaching screening, immediate referral of HIV positives to medical treatment and partner notification. We tested the performance characteristics of an oral fluid-based rapid HIV test (Rapidtest HIV lateral flow-Healthchem diag. LLC) in comparison with routinely utilized methods in a selected population of known positive (N = 121) or negative (N = 754) subjects. The sensitivity of the rapid test was 99.1% (one false negative sample) and the specificity 98.8%. Five negatives showed a faint reactivity, 3 of these were reactive also in the reference test, one with a p24 only reaction in Western blot. If these 3 samples were excluded from the analysis the specificity increases to 99.2%. Results from our study confirm that, although a continuous improvement of the test performance is still needed to minimize false negative and positive results, rapid test and alternative biological samples may contribute to HIV prevention strategies by reaching a larger population particularly when and where regular screening procedures are difficult to obtain.

    Cervical cancer is the third most prevalent cancer in women around the world. Recently in Korea, the incidence of cervical cancer has decreased, but in all stages of cervical intraepithelial neoplasia (CIN), CIN has shown a 91% increase from 1999 to 2008. Persistent human papillomavirus (HPV) infection has been found to be the main cause of cervical cancer. HPV types 16 and 18 have been found in 70% of cervical cancer patients around the world. Cervical cancer screening such as cytology has limitations in terms of sensitivity and specificity. A discussion about the need for the HPV test is becoming active in order to compensate for the limitation of cytology. After the role of HPV in cervical cancer was identified, the importance of HPV detection test as a screening was emphasized. Several tests have been developed and each test has its own advantages and disadvantages, and new test method to overcome the disadvantages is still being developed. Today's guidelines and tests are those you would choose from among the large number of cervical cancer screening guidelines and tests, based on the consideration that the selected guidelines and the test are effective.

    Much of the suffering and death from cancer could be prevented by more systematic efforts to reduce tobacco use, improve diet, increase physical activity, reduce obesity, and expand the use of established screening tests. Monitoring the prevalence of cancer risk factors and screening is important to measure progress and strengthen cancer prevention and early detection efforts. In this review article, we provide recent prevalence estimates for several cancer risk factors, including tobacco, obesity, physical activity, nutrition, ultraviolet radiation exposure as well as human papillomavirus and hepatitis B vaccination coverage and cancer screening prevalence in the United States. In 2013, cigarette smoking prevalence was 17.8% among adults nationally, but ranged from 10.3% in Utah to 27.3% in West Virginia. In addition, 15.7% of U.S. high school students were current smokers. In 2011-2012, obesity prevalence was high among both adults (34.9%) and adolescents (20.5%), but has leveled off since 2002. About 20.2% of high school girls were users of indoor tanning devices, compared with 5.3% of boys. In 2013, cancer screening prevalence ranged from 58.6% for colorectal cancer to 80.8% for cervical cancer and remains low among the uninsured, particularly for colorectal cancer screening where only 21.9% of eligible adults received recommended colorectal cancer screening.

    Continuing efforts to improve the University of San Francisco/NASA toxicity screening test method have included the addition of exercise wheels to provide a different measure of incapacitation, and oxygen replenishment to offset any effect of oxygen depletion by the test animals. The addition of exercise wheels limited the number of animals in each test and doubled the required number of tests without any significant improvement in reproducibility. Oxygen replenishment appears to have an effect on survival in the last 5 minutes of the 30-minute test, but the effect is expected to be similar for most materials.

    Lateral flow assay tests are nowadays becoming powerful, low-cost diagnostic tools. Obtaining a result is usually subject to visual interpretation of colored areas on the test by a human operator, introducing subjectivity and the possibility of errors in the extraction of the results. While automated test readers providing a result-consistent solution are widely available, they usually lack portability. In this paper, we present a smartphone-based automated reader for drug-of-abuse lateral flow assay tests, consisting of an inexpensive light box and a smartphone device. Test images captured with the smartphone camera are processed in the device using computer vision and machine learning techniques to perform automatic extraction of the results. A deep validation of the system has been carried out showing the high accuracy of the system. The proposed approach, applicable to any line-based or color-based lateral flow test in the market, effectively reduces the manufacturing costs of the reader and makes it portable and massively available while providing accurate, reliable results.

    AIM To measure the compliance of an Academic Hospital staff with a colorectal cancer (CRC) screening program using fecal immunochemical test (FIT). METHODS All employees of “Attikon” University General Hospital aged over 50 years were thoroughly informed by a team of physicians and medical students about the study aims and they were invited to undergo CRC screening using two rounds of FIT (DyoniFOB® Combo H, DyonMed SA, Athens, Greece). The tests were provided for free and subjects tested positive were subsequently referred for colonoscopy. One year after completing the two rounds, participants were asked to be re-screened by means of the same test. RESULTS Among our target population consisted of 211 employees, 59 (27.9%) consented to participate, but only 41 (19.4%) and 24 (11.4%) completed the first and the second FIT round, respectively. Female gender was significantly associated with higher initial participation (P = 0.005) and test completion - first and second round - (P = 0.004 and P = 0.05) rates, respectively. Physician’s (13.5% vs 70.2%, P < 0.0001) participation and test completion rates (7.5% vs 57.6%, P < 0.0001 for the first and 2.3% vs 34%, P < 0.0001 for the second round) were significantly lower compared to those of the administrative/technical staff. Similarly, nurses participated (25.8% vs 70.2%, P = 0.0002) and completed the first test round (19.3% vs 57.6%, P = 0.004) in a significant lower rate than the administrative/technical staff. One test proved false positive. No participant repeated the test one year later. CONCLUSION Despite the well-organized, guided and supervised provision of the service, the compliance of the Academic Hospital personnel with a FIT-based CRC screening program was suboptimal, especially among physicians.

    Objective: To develop a screening test to detect female college athletes with eating disorders/disordered eating (ED/ DE). No validated eating disorder screening tests specifically for athletes have been available. Design and Setting: In this cross-sectional study, subjects from a large midwestern university completed 3 objective tests and a structured diagnostic interview. Measurements: A new test, developed and pilot tested by the researchers (Athletic Milieu Direct Questionnaire, AMDQ), and 2 tests normed for the general population (Eating Disorder Inventory-2, Bulimia Test-Revised) were used to identify ED/DE athletes. A structured, validated, diagnostic interview (Eating Disorder Examination, version 12.OD) was used to determine which test was most effective in screening female college athletes. Subjects: Subjects included 149 female athletes, ages 18 to 25 years, from 11 Division I and select club sports. Results: ED/DE subjects (35%) were found in almost every sport. Of the ED/DE subjects, 65% exhibited disordered eating, 25% were bulimic, 8% were classified as eating disordered not otherwise specified (NOS), and 2% were anorexic. The AMDQ more accurately identified ED/DE than any test or combination of items. The AMDQ produced superior results on 7 of 9 epidemiologic analyses; sensitivity was 80% and specificity was 77%, meaning that it correctly classified approximately 4 of every 5 persons who were truly exhibiting an eating disorder or disordered eating. Conclusions: We recommend that the AMDQ subsets, which met statistical criteria, be used to screen for ED/DE to enable early identification of athletes at the disordered eating or NOS stage and to initiate interventions before the disorder progresses.

    The objective of this study is to compare and evaluate the diagnostic value of hereditary spherocytosis (HS) by three screening tests, comparing mean spherical corpuscular volume (MSCV) to mean corpuscular volume (MCV), mean corpuscular hemoglobin concentration (MCHC), and flow cytometric osmotic fragility test. Peripheral blood was collected from 237 participators diagnosed at the First Affiliated Hospital of Guangxi Medical University, including 56 hereditary spherocytosis patients, 86 thalassemia patients, and 95 healthy people. The samples were examined by three tests, and the three screening tests were evaluated by the sensitivity and specificity of tests. The sensitivity was only 41.07%, and specificity was 94.47% when using MCHC >355 g/L as diagnostic criteria. The sensitivity was 89.28%, and specificity was 96.14% when using MSCV < MCV as the optimum cutoff point. When using the residual red cell percentage <23.6% as the diagnostic threshold in flow cytometric osmotic fragility test, the sensitivity was 85.71% and the specificity was 97.24%. Flow cytometry osmotic fragility test or comparing MSCV to MCV combined with smear examination of peripheral red blood cells morphology can be a simple, practical, and accurate hereditary spherocytosis (HS) laboratory screening method.

    The Electric Power Research Institute (EPRI) developed a fish diversion screen, known as the Modular Inclined Screen (MIS), to prevent fish mortality at water intakes. hydraulic model testing and successful biological evaluation of the MIS had been completed in the laboratory. Following discussions with various federal and state agencies, the Green Island hydroelectric Project was selected as the field test location. This project is located on the Hudson River, just north of Albany, in Green Island, New York. The MIS test facility was operated and tested in the fall of 1995. In addition to the MIS, the effectiveness of a strobe light system was studied to determine its ability to divert blueblack herring form the river to the MIS.

    Drug abuse with illicit drugs and licit drugs has been increasing steadily over the past decade. A recent National Household Survey on Drug Abuse found statistically significant increases between 2000 and 2001 in the use of multiple drugs, including marijuana, cocaine, and non-medical use of pain relievers and tranquilizers. Prescription controlled substance abuse is a major issue in chronic pain management. Various means suggested to avoid or monitor abuse in patients in treatment include urine/serum drug screening whenever requested, along with other precautions including one prescribing physician and one designated pharmacy, etc. Based on the present evidence, physicians assume that patients adhering to controlled substance agreements and without obvious dependency behavior do not abuse either illicit or licit drugs. Thus, it is accepted that there is no necessity to perform routine urine/drug testing in this specific group of the patient population. One hundred patients undergoing interventional pain management and receiving controlled substances were randomly selected for evaluation of illicit drug abuse by urine drug testing. They were selected from a total of 250 patients who were identified as non-abusers of prescription drugs. Results showed that illicit drug abuse in patients without history of controlled substance abuse was seen in 16 patients. Thirteen of the 16 patients tested positive for marijuana and 3 patients tested positive for cocaine. Only one patient tested positive for a combined use of both marijuana and cocaine. This study showed that, in an interventional pain management setting, there is significant use of illicit drugs (16%) with 13% use of marijuana and 3% use of cocaine in patients who are considered as non-abusers of prescription controlled substances and those who are adherent to controlled substance agreements. However, if cocaine is considered as a hardcore drug in contrast to marijuana, abuse of hardcore illicit drugs is only 3

    Reliable identification of carbapenemase-producing members of the family Enterobacteriaceae is necessary to limit their spread. This study aimed to develop a diagnostic flow chart using phenotypic screening and confirmation tests that is suitable for implementation in different types of clinical laboratories. A total of 334 clinical Enterobacteriaceae isolates genetically characterized with respect to carbapenemase, extended-spectrum β-lactamase (ESBL), and AmpC genes were analyzed. A total of 142/334 isolates (42.2%) were suspected of carbapenemase production, i.e., intermediate or resistant to ertapenem (ETP) and/or meropenem (MEM) and/or imipenem (IPM) according to EUCAST clinical breakpoints (CBPs). A group of 193/334 isolates (57.8%) showing susceptibility to ETP, MEM, and IPM was considered the negative-control group in this study. CLSI and EUCAST carbapenem CBPs and the new EUCAST MEM screening cutoff were evaluated as screening parameters. ETP, MEM, and IPM with or without aminophenylboronic acid (APBA) or EDTA combined-disk tests (CDTs) and the Carba NP-II test were evaluated as confirmation assays. EUCAST temocillin cutoffs were evaluated for OXA-48 detection. The EUCAST MEM screening cutoff (<25 mm) showed a sensitivity of 100%. The ETP APBA CDT on Mueller-Hinton agar containing cloxacillin (MH-CLX) displayed 100% sensitivity and specificity for class A carbapenemase confirmation. ETP and MEM EDTA CDTs showed 100% sensitivity and specificity for class B carbapenemases. Temocillin zone diameters/MIC testing on MH-CLX was highly specific for OXA-48 producers. The overall sensitivity, specificity, positive predictive value, and negative predictive value of the Carba NP-II test were 78.9, 100, 100, and 98.7%, respectively. Combining the EUCAST MEM carbapenemase screening cutoff (<25 mm), ETP (or MEM), APBA, and EDTA CDTs, and temocillin disk diffusion on MH-CLX promises excellent performance for carbapenemase detection.

    JAK2V617F is sufficiently prevalent in BCR-ABL1-negative myeloproliferative neoplasms (MPNs) to be useful as a clonal marker. JAK2V617F mutation screening is indicated for the evaluation of erythrocytosis, thrombocytosis, splanchnic vein thrombosis, and otherwise unexplained BCR-ABL1-negative granulocytosis. However, the mutation does not provide additional value in the presence of unequivocal morphologic diagnosis, and its presence does not necessarily distinguish one MPN from another or provide useful prognostic information. In general, quantitative cell-based JAK2V617F mutation assays are preferred because the additional information obtained on mutant allele burden enhances diagnostic certainty and facilitates monitoring of response to treatment. JAK2 exon 12 mutation screening is indicated only in the presence of JAK2V617F-negative erythrocytosis that is associated with a subnormal serum erythropoietin level. MPL mutations are neither frequent nor specific enough to warrant their routine use for MPN diagnosis, but they may be useful in resolving specific diagnostic problems. The practice of en bloc screening for JAK2V617F, JAK2 exon 12, and MPL mutations is scientifically irrational and economically irresponsible. PMID:21723416

    OBJECTIVES: We investigated the within-group and between-group variation in prenatal HIV testing in a sample of low-income pregnant and recently postpartum women. METHODS: Multivariable linear regression was used to estimate proportional differences in prenatal HIV testing for the total sample and stratified by race. RESULTS: In bivariate analyses, race and site of care jointly affected the probability of being tested. Hispanic women had the highest probability of being tested in public practice settings but relative to white women, black women had a higher probability of being tested in public and private practice settings. Predictors of prenatal HIV testing differed by race. Receiving prenatal care in a community health center or hospital outpatient clinic increased the probability of testing for Hispanics. Being a recent victim of intimate partner violence was associated with less frequent testing for blacks. Positive beliefs about HIV screening, while significant for blacks and Hispanics, was the only factor associated with testing for whites. CONCLUSION: Our data suggest that racial biases may be influencing providers' approach to testing, rather than CDC's 2001 guidelines for HIV screening of pregnant women. Study findings are being used to modify social marketing campaigns and improve provider trainings regarding prenatal HIV testing. PMID:16080457

  11. The use of the osmole gap as a screening test for the presence of exogenous substances.

    The rapid and accurate diagnosis of toxic alcohol poisoning due to methanol (methyl alcohol) [MeOH] and ethylene glycol (EG), is paramount in preventing serious adverse outcomes. The quantitative measurement of specific serum levels of these substances using gas chromatography is expensive, time consuming and generally only available at major tertiary-care facilities. Therefore, because these toxic substances are osmotically active and the measurement of serum osmolality is easily performed and more readily available, the presence of an osmole gap (OG) has been adopted as an alternative screening test. By definition, the OG is the difference between the measured serum osmolality determined using the freezing point depression (Osm(m)) and the calculated serum molarity (Mc), which is estimated from the known and readily measurable osmotically active substances in the serum, in particular sodium, urea, glucose, and potassium and ethanol (alcohol). Thus, the OG=Osm(m)-Mc, and an OG above a specific threshold (the threshold of positivity) suggests the presence of unmeasured osmotically active substances, which could be indicative of a toxic exposure. The objectives of this study were to review the principles of evaluating screening tests, the theory behind the OG as a screening test and the literature upon which the adoption of the OG as a screening test has been based. This review revealed that there have been numerous equations derived and proposed for the estimation of the Mc, with the objective of developing empirical evidence of the best equation for the determination of the OG and ultimately the utility of OG as a screening test. However, the methods and statistical analysis employed have generally been inconsistent with recommended guidelines for screening test evaluation and although many equations have been derived, they have not been appropriately validated. Specific evidence of the clinical utility of the OG requires that a threshold of positivity be

    Dementia is a common and under-diagnosed problem among the elderly. An accurate screening test would greatly aid the ability of physicians to evaluate dementia and memory problems in clinical practice. We sought to determine whether simple and brief psychometric tests perform similarly to the Mini-Mental State Examination (MMSE) in screening for dementia. Using a retrospective analysis, a series of standard, brief, psychometric tests were compared with each other and to the MMSE as screening tests for very mild dementia, using DSM-III-R criterion as the gold standard. Two independent cohorts from the Baltimore Longitudinal Study of Aging and the Washington University Alzheimer's Disease Research Center were evaluated. We found that two brief and simple-to-administer tests appear to offer similar degrees of sensitivity and specificity to the MMSE. These are the recall of a five-item name and address, "John Brown 42 Market Street Chicago" and the one-minute verbal fluency for animals. Combining these two tests further improves sensitivity and specificity, surpassing the MMSE, to detect dementia in individuals with memory complaints. PMID:15764865

    This work aims to estimate celiac disease prevalence in school-children in the island of Djerba and assess rapid method feasibility for screening. We screened 2064 schoolchildren by a rapid method to detect IgA anti-tissue transglutaminase and IgA deficiency. Children with positive results were tested for IgA anti-transglutaminase and anti-endomysium by conventional tests. In positive children, intestinal biopsy was performed. IgA deficiency suspected by rapid method was confirmed by nephelometry. In these cases IgG anti-endomysium was performed. Rapid test was positive in 7 children; conventional serology was positive in all and 6 of them accepted the biopsy. Total villous atrophy was observed in 5 while intestinal mucosa was normal in one. Among children with positive serology, 3 had silent form, 1 chronic diarrhea, one growth failure and 2 had borderline growth. IgA deficiency was suspected in 13 cases and was confirmed in 11 children tested. Prevalence of celiac disease was 0.24-0.34% and that of IgA deficiency 0.5-0.6%. This screening study confirms that celiac disease is relatively common in schoolchildren in Tunisia. It confirms also that even those with symptoms typical for celiac disease escape diagnosis. Rapid test is better accepted by parents and children than test requiring a venous blood sample. PMID:23883201

    A novel method for the screening of 151 drugs of abuse and toxic compounds in human whole blood has been developed and validated by online solid-phase extraction with liquid chromatography coupled to time-of-flight mass spectrometry. Analytes were extracted and separated by using a fully automated online solid-phase extraction liquid chromatography system with total chromatographic run time of 26 min. Time-of-flight mass spectrometry screening of 151 drugs of abuse and toxic compounds was performed in a full-scan (m/z 50-800) mode using an MS(E) acquisition of molecular ions and fragment ions data at two collision energies (one was 6 eV and another one was in the range of 5-45 eV). The compounds were identified based on retention times and exact mass of molecular ions and fragment ions. The limit of detection ranged from 1 to 100 ng/mL and the recovery of the method ranged from 6.3 to 163.5%. This method is proved to be a valuable screening method allowing fast and specific identification of drugs in human whole blood. PMID:25348371

    The triple test is a second trimester screening test used to identify those pregnant women who should be offered a diagnostic test to identify whether their fetus has an aneuploidy. It was first described in 1988, but has largely been superseded by newer tests either conducted earlier in the first trimester (ie, the combined test, using ultrasound measurement of nuchal translucency, pregnancy-associated plasma protein A, and human chorionic gonadotrophin [hCG]) or in the second trimester (ie, the quadruple test, using α-fetoprotein, hCG, uE3, and inhibin). These newer tests have been introduced because they offer greater detection and lower screen positive results thereby enhancing diagnosis rates, while decreasing the risk of iatrogenic harm caused by the invasive testing required when collecting suitable sample tissue. Noninvasive alternatives to the triple test have been identified, but these have not been adopted despite 13 years of development. It is likely, therefore, that the triple test (or variants thereof) will continue to be used in routine antenatal care for the foreseeable future. PMID:21072301

    It is not easy to differentiate patients with mild cognitive impairment (MCI) from subjective memory complainers (SMC). Assessments with screening cognitive tools are essential, particularly in primary care where most patients are seen. The objective of this study was to evaluate the diagnostic accuracy of screening cognitive tests and to propose a score derived from screening tests. Elderly subjects with memory complaints were evaluated using the Mini Mental State Examination (MMSE) and the Brief Cognitive Battery (BCB). We added two delayed recalls in the MMSE (a delayed recall and a late-delayed recall, LDR), and also a phonemic fluency test of letter P fluency (LPF). A score was created based on these tests. The diagnoses were made on the basis of clinical consensus and neuropsychological testing. Receiver operating characteristic curve analyses were used to determine area under the curve (AUC), the sensitivity and specificity for each test separately and for the final proposed score. MMSE, LDR, LPF and delayed recall of BCB scores reach statistically significant differences between groups (P=0.000, 0.03, 0.001 and 0.01, respectively). Sensitivity, specificity and AUC were MMSE: 64%, 79% and 0.75 (cut off <29); LDR: 56%, 62% and 0.62 (cut off <3); LPF: 71%, 71% and 0.71 (cut off <14); delayed recall of BCB: 56%, 82% and 0.68 (cut off <9). The proposed score reached a sensitivity of 88% and 76% and specificity of 62% and 75% for cut off over 1 and over 2, respectively. AUC were 0.81. In conclusion, a score created from screening tests is capable of discriminating MCI from SMC with moderate to good accurancy. PMID:24147213

    Printable and flexible electronics are increasingly being used in numerous applications that are miniaturized, multi-functional and lightweight. Simultaneously, reliability issues of the printed and flexible electronic devices are getting more attention. The adhesion of screen-printed silver (Ag) tracks on a polyimide (PI) film was investigated after two kinds of the environmental reliability test: a constant-temperature storage test, and a steady-state temperature and humidity storage test. Atmospheric-pressure plasma (APP) was adopted on the PI film surface to improve the poor adhesion derived from the inherent hydrophobicity. The Ag tracks constructed via screen printing were sintered at 250 degrees C for 30 min in air using a box-type muffle furnace. Some samples were exposed under 85 degrees C and 85% relative humidity (RH) for various durations (24, 72, 168 and 500 h), and others were aged at 85 degrees C with same durations to compare the influence of moisture on the adhesion. The adhesion of the screen-printed Ag tracks was evaluated by a roll-type 90 degrees peel test. The peel strength of the screen-printed Ag tracks decreased by 76.74% and 69.88% after 500 h run of the 85 degrees C/85% RH test, and the aging test, respectively. The weakest adhesion was 4.98 gf/mm after the 500 h run of the 85 degrees C/85% RH test. To demonstrate these experimental results, the microstructural evolution and chemical bonding states of the interfacial surfaces were characterized using a field emission scanning electron microscope (FE-SEM), and X-ray photoelectron spectroscope (XPS), respectively.

    A serological study was carried out in Tiaret province in western Algeria on 1032 cows distributed in 95 flocks to estimate the prevalence of Brucella infection and to compare the sensitivity and specificity of a range of agglutination tests. Screening tests showed 31.5% of herds positive using the buffered plate antigen test and 26.3% using the rose Bengal test compared with 15.7% with the complement fixation test. Using the complement fixation test as the gold standard for confirmatory tests, the Rivanol test was found to be more sensitive but less specific than tube agglutination in detecting brucellosis infection. Three isolates were identified from 105 blood samples from humans with brucellosis and 50 samples of milk and tissues from infected cows and they were all Brucella melitensis biovar 3. PMID:17037229

    Hearing loss is widespread among the elderly. One of the main obstacles to rehabilitation is identifying individuals with potentially correctable hearing loss. Smartphone-based hearing tests can be administered at home, thus greatly facilitating access to screening. This study evaluates the use of a smartphone application as a screening tool for hearing loss in individuals aged ≥ 65 years. Twenty-six subjects aged 84.4 ± 6.73 years (mean ± SD) were recruited. Pure-tone audiometry was administered by both a smartphone application (uHear for iPhone, v1.0 Unitron, Canada) and a standard portable audiometer by trained personnel. Participants also completed a questionnaire on their hearing. Pure-tone thresholds were compared between the two testing modalities and correlated with the questionnaire results. The cutoff point for failing screening tests was a pure tone average of 40 dB for the frequencies 250-6,000 Hz. The smartphone application's pure tone thresholds were higher (poorer hearing) than the audiometric thresholds, with a significant difference in all frequencies but 2,000 Hz. The application and the audiometric values were in agreement for 24 subjects (92 %). The application had a sensitivity of 100 % and specificity of 60 % for screening compared with the audiometer. The questionnaire was significantly less accurate, having assigned a passing score to three participants who failed both the application and audiometric tests. While a smartphone application may not be able to accurately determine the level of hearing impairment, it is useful as a highly accessible portable audiometer substitute for screening for hearing loss in elderly populations.

    The impact of child abuse on the developmental functioning of infants was investigated. Thirty verified cases of physically abused children were compared to a reference group of 30 nonabused children matched for age, sex, race, and socioeconomic status. Abused children scored significantly lower in terms of cognitive and motor development as measured by the Bayley Scales of Infant Development. Development delays on three of the four sectors of the Denver Developmental Screening Test, personal-social, language, and gross motor, were also found in the abused children. There were, however, relatively few item differences between the two groups on the 30 more general behavioral variables constituting the Bayley Infant Behavior Record. Results appear to confirm clinical observation of abused children as developmentally retarded with specific delays in the language and gross motor areas. Although methodologically complex, longitudinal studies are clearly indicated to assess the stability and/or reversibility of the present findings. PMID:75219

    Screening for colorectal cancer by means of unhydrated Hemoccult (HO) is in progress in the Province of Florence since 1982. In 1990 rehydrated HO was introduced in the town of Empoli. Five adjacent municipalities where screening had started in 1987 were selected for comparison. In both areas subjects aged 40-70 were invited by mail to undergo the screening protocol. HO-positive subjects were invited to undergo either pancolonoscopy or a combination of left colonoscopy and double contrast barium enema. HO-negative subjects were invited to repeat screening 2 years later. The positivity rate of HO was significantly higher (P < 0.001) for rehydrated (5%) as compared to unhydrated (3.1%) HO. The positive predictive values for cancer (unhydrated: 5.8%; rehydrated: 8.9%) and for adenomas (unhydrated: 26.7%; rehydrated: 25.5%) did not significantly differ. The detection rates of rehydrated HO were significantly higher as compared to unhydrated HO both for cancer (0.37% vs 0.15%; P < 0.05) and adenomas (1.06% vs 0.72%; P < 0.05%). In the present experience rehydration doesn't produce any decrease in the positive predictive value for cancer or adenomas and the increase in the positivity rate appears quite acceptable when considering the significant increase in the detection rates of cancer and adenomas. We conclude that rehydrated HO should be introduced as the standard test for screening in order to increase sensitivity for colorectal cancer and adenomas. PMID:8494714

    The performance of all four GOLD scoring functions has been evaluated for pose prediction and virtual screening under the standardized conditions of the comparative docking and scoring experiment reported in this Edition. Excellent pose prediction and good virtual screening performance was demonstrated using unmodified protein models and default parameter settings. The best performing scoring function for both pose prediction and virtual screening was demonstrated to be the recently introduced scoring function ChemPLP. We conclude that existing docking programs already perform close to optimally in the cognate pose prediction experiments currently carried out and that more stringent pose prediction tests should be used in the future. These should employ cross-docking sets. Evaluation of virtual screening performance remains problematic and much remains to be done to improve the usefulness of publically available active and decoy sets for virtual screening. Finally we suggest that, for certain target/scoring function combinations, good enrichment may sometimes be a consequence of 2D property recognition rather than a modelling of the correct 3D interactions.

    The translational value of zebrafish high-throughput screens can be improved when more knowledge is available on uptake characteristics of potential drugs. We investigated reference antibiotics and 15 preclinical compounds in a translational zebrafish-rodent screening system for tuberculosis. As a major advance, we have developed a new tool for testing drug uptake in the zebrafish model. This is important, because despite the many applications of assessing drug efficacy in zebrafish research, the current methods for measuring uptake using mass spectrometry do not take into account the possible adherence of drugs to the larval surface. Our approach combines nanoliter sampling from the yolk using a microneedle, followed by mass spectrometric analysis. To date, no single physicochemical property has been identified to accurately predict compound uptake; our method offers a great possibility to monitor how any novel compound behaves within the system. We have correlated the uptake data with high-throughput drug-screening data from Mycobacterium marinum-infected zebrafish larvae. As a result, we present an improved zebrafish larva drug-screening platform which offers new insights into drug efficacy and identifies potential false negatives and drugs that are effective in zebrafish and rodents. We demonstrate that this improved zebrafish drug-screening platform can complement conventional models of in vivo Mycobacterium tuberculosis-infected rodent assays. The detailed comparison of two vertebrate systems, fish and rodent, may give more predictive value for efficacy of drugs in humans. PMID:25385118

  8. The impact of financing of screening tests on utilization and outcomes: The case of amniocentesis.

    2016-07-01

    We use a 1993 policy change in Israel's public healthcare system that lowered the eligibility age for amniocentesis to 35 to study the effects of financing of screening tests. Financing is found to have increased amniocentesis testing by about 35%. At ages above the eligibility threshold, utilization rates rose to roughly 33%, reflection nearly full takeup among prospective users of amniocentesis. Additionally, whereas below the age-35 threshold amniocentesis utilization rates increase with maternal age, this relation is muted above this age. Finally, no evidence is found that financing affects outcomes such as pregnancy terminations and births of children with Down syndrome. These results support the view that women above the eligibility threshold tend to refrain from acquiring inexpensive information about their degree of risk that absent the financing they would acquire, and instead, undergo the accurate and costly test regardless of additional information that noninvasive screening would provide.

    A new test for the diagnosis of Gaucher disease is described. The test is designed to screen large numbers of clinical specimens from high-risk populations. It consists of duplex PCR amplification of genomic DNA followed by hybridization to alkaline phosphatase-conjugated allele-specific oligonucleotide probes (ASOs). High melting temperature PCR primers were used to increase specificity and eliminate the need for a separate annealing step. All hybridization and washing steps were performed at one temperature. Chemiluminescent detection of signals is fast, and results are easily interpreted directly from x-ray films. Currently, the test is being used in our laboratories to screen Ashkenazi Jewish populations in whom Gaucher disease is common. PMID:9018309

    The continuing emergence of designer drugs imposes high demands on the scope and sensitivity of toxicological drug screening procedures. An ultra-high performance liquid chromatography/high-resolution time-of-flight mass spectrometry (UHPLC-HR-TOFMS) method was developed for screening and simultaneous confirmation of both designer drugs and other drugs of abuse in urine samples in a single run. The method covered selected synthetic cannabinoids and cathinones, amphetamines, natural cannabinoids, opioids, cocaine and other important drugs of abuse, together with their main urinary metabolites. The database consisted of 277 compounds with molecular formula and exact monoisotopic mass; retention time was included for 192 compounds, and primary and secondary qualifier ion exact mass for 191 and 95 compounds, respectively. Following a solid-phase extraction, separation was performed by UHPLC and mass analysis by HR-TOFMS. MS, and broad-band collision-induced dissociation data were acquired at m/z range 50-700. Compound identification was based on a reverse database search with acceptance criteria for retention time, precursor ion mass accuracy, isotopic pattern and abundance of qualifier ions. Mass resolving power in spiked urine samples was on average FWHM 23,500 and mass accuracy 0.3 mDa. The mean and median cut-off concentrations determined for 75 compounds were 4.2 and 1 ng/mL, respectively. The range of cut-off concentrations for synthetic cannabinoids was 0.2-60 ng/mL and for cathinones 0.7-15 ng/mL. The method proved to combine high sensitivity and a wide scope in a manner not previously reported in drugs of abuse screening. The method's feasibility was demonstrated with 50 authentic urine samples. PMID:23954996

    Patients with Parkinson's disease (PD) experience both motor output deficits and cognitive disabilities. Various PD rodent models have been developed to investigate the genetic and brain circuit-related causes of PD and have contributed to the basic and clinical research and to therapeutic strategies for this disease. Most studies using PD rodent models have focused on the motor output deficits, rather than cognitive disabilities due to the lack of appropriate testing tools that do not require significant motor abilities. In this study, we assessed the cognitive disabilities of PD model mice using a touch screen test that required only little motor ability. We found that the PD model mice, which had motor deficits caused by unilateral striatal dopaminergic degeneration, successfully underwent operant conditioning with a touch screen test. Additionally, we found that the PD model mice demonstrated impaired location discrimination, but intact attention and reversal learning in the cognitive tests. Therefore, the touch screen test is useful for assessing hidden cognitive disabilities in disease model animals with decreased motor function. PMID:26698399

    The purpose of this study was to compare physicians', midwives' and lay people's attitudes towards genetic screening and testing to find out whether medical education and experience influence attitudes of genetic screening and testing. The study was based on comparison of answers to joint questions in three different cross-sectional postal surveys between October 1996 and April 1998 in Finland. Target groups were physicians (study base n=772, response rate 74%, including gynaecologists, paediatricians, general practitioners and clinical geneticists), midwives and public health nurses (collectively referred to as midwives in the following; n=800, response rate 79%), and lay people (n=2000, response rate 62%). Midwives were more worried about the consequences of genetic testing and stressed the autonomy of the customer more strongly than lay people did. Furthermore, professionals considered that lay peoples' expectations as regards to genetic testing are too high. Having more medical education was related to having less 'cannot say' and missing responses. Our results do not suggest that major conflicts about the direction of genetic testing and screening would arise in near future. However, different positions and interests should be considered. Reporting in public about new prospects and developments in medical genetics should pay more attention also to concerns for balancing promises and drawbacks. PMID:12891376

    Neuropsychological tests of visual perception mostly assess high-level processes like object recognition. Object recognition, however, relies on distinct mid-level processes of perceptual organization that are only implicitly tested in classical tests. Furthermore, the psychometric properties of the existing instruments are limited. To fill this gap, the Leuven perceptual organization screening test (L-POST) was developed, in which a wide range of mid-level phenomena are measured in 15 subtests. In this study, we evaluated reliability and validity of the L-POST. Performance on the test is evaluated relative to a norm sample of more than 1,500 healthy control participants. Cronbach's alpha of the norm sample and test-retest correlations for 20 patients provide evidence for adequate reliability of L-POST performance. The convergent and discriminant validity of the test was assessed in 40 brain-damaged patients, whose performance on the L-POST was compared with standard clinical tests of visual perception and other measures of cognitive function. The L-POST showed high sensitivity to visual dysfunction and decreased performance was specific to visual problems. In conclusion, the L-POST is a reliable and valid screening test for perceptual organization. It offers a useful online tool for researchers and clinicians to get a broader overview of the mid-level processes that are preserved or disrupted in a given patient. PMID:25042381

    Background: The aim of screening for colorectal cancer is to improve prognosis by the detection of cancer at its early stages. In order to inform the decision on the specific test to be used in the population-based program in the Basque Autonomous Region (Spain), we compared two immunochemical fecal occult blood quantitative tests (I-FOBT). Methods: Residents of selected study areas, aged 50–69 years, were invited to participate in the screening. Two tests based on latex agglutination (OC-Sensor and FOB Gold) were randomly assigned to different study areas. A colonoscopy was offered to patients with a positive test result. The cut-off point used to classify a result as positive, according to manufacturer’s recommendations, was 100 ng/ml for both tests. Results: The invited population included 37,999 individuals. Participation rates were 61.8% (n = 11,162) for OC-Sensor and 59.1% (n = 11,786) for FOB Gold (p = 0.008). Positive rate for OC-Sensor was 6.6% (n = 737) and 8.5% (n = 1,002) for FOB Gold (p < 0.0001). Error rates were higher for FOB gold (2.3%) than for OC-Sensor (0.2%; p < 0.0001). Predictive positive value (PPV) for total malignant and premalignant lesions was 62.4% for OC-Sensor and 58.9% for FOB Gold (p = 0.137), respectively. Conclusion: OC-Sensor test appears to be superior for I-FOBT-based colorectal cancer screening, given its acceptance, ease of use, associated small number of errors and its screening accuracy. FOB Gold on the other hand, has higher rate of positive values, with more colonoscopies performed, it shows higher detection incidence rates, but involves more false positives. PMID:24454288

    Purpose: To establish the extent to which test set reading can represent actual clinical reporting in screening mammography. Materials and Methods: Institutional ethics approval was granted, and informed consent was obtained from each participating screen reader. The need for informed consent with respect to the use of patient materials was waived. Two hundred mammographic examinations were selected from examinations reported by 10 individual expert screen readers, resulting in 10 reader-specific test sets. Data generated from actual clinical reports were compared with three test set conditions: clinical test set reading with prior images, laboratory test set reading with prior images, and laboratory test set reading without prior images. A further set of five expert screen readers was asked to interpret a common set of images in two identical test set conditions to establish a baseline for intraobserver variability. Confidence scores (from 1 to 4) were assigned to the respective decisions made by readers. Region-of-interest (ROI) figures of merit (FOMs) and side-specific sensitivity and specificity were described for the actual clinical reporting of each reader-specific test set and were compared with those for the three test set conditions. Agreement between pairs of readings was performed by using the Kendall coefficient of concordance. Results: Moderate or acceptable levels of agreement were evident (W = 0.69–0.73, P < .01) when describing group performance between actual clinical reporting and test set conditions that were reasonably close to the established baseline (W = 0.77, P < .01) and were lowest when prior images were excluded. Higher median values for ROI FOMs were demonstrated for the test set conditions than for the actual clinical reporting values; this was possibly linked to changes in sensitivity. Conclusion: Reasonable levels of agreement between actual clinical reporting and test set conditions can be achieved, although inflated sensitivity

    The purpose of this paper is to examine the key parameters that affect the bubble point pressure for screen channel Liquid Acquisition Devices in cryogenic liquid oxygen at elevated pressures and temperatures. An in depth analysis of the effect of varying temperature, pressure, and pressurization gas on bubble point is presented. Testing of a 200 x 1400 and 325 x 2300 Dutch Twill screen sample was conducted in the Cryogenics Components Lab 7 facility at the NASA Glenn Research Center in Cleveland, Ohio. Test conditions ranged from 92 to 130K and 0.138 - 1.79 MPa. Bubble point is shown to be a strong function of temperature with a secondary dependence on pressure. The pressure dependence is believed to be a function of the amount of evaporation and condensation occurring at the screen. Good agreement exists between data and theory for normally saturated liquid but the model generally under predicts the bubble point in subcooled liquid. Better correlation with the data is obtained by using the liquid temperature at the screen to determine surface tension of the fluid, as opposed to the bulk liquid temperature.

    Four methods intended for screening muscle tissue for residues belonging to the tetracycline group were compared using artificially contaminated as well as incurred samples. Two agar diffusion methods were studied: one with Bacillus subtilis as a test strain, the second with Bacillus cereus. Two variants of each method were compared: thin plates for analysis of intact or minced meat, and thick plates for analysis of meat fluid. The thin plate variants could not be evaluated with artificially contaminated samples because it was impossible to prepare homogeneously spiked, undiluted meat. The thick plates were suited for doxycycline and chlortetracycline, but they did not detect oxytetracycline or tetracycline in spiked meat fluid. The results of these tests done on incurred meat were very good for doxycycline and satisfying or just failing for oxytetracycline, while the best detection capability was obtained when intact frozen meat was examined on thin plates seeded with B. cereus. Two commercially available screening tests were also evaluated. The Premi(R) test, an inhibitor test with Bacillus stearothermophilus as a test strain and an indicator for growth, was not suited for detection of tetracyclines up to the maximum residue limit. Tetrasensor(R), a receptor test specific for tetracyclines, proved a quick and simple test able to detect meat samples artificially contaminated with tetracycline, oxytetracycline, doxycycline or chlortetracycline, as well as meat incurred with oxytetracycline or doxycycline.

    This study explored federally qualified health center (FQHC) patients' perceptions about colorectal cancer screening (CRCS) tests, including immunochemical fecal occult blood tests (iFOBT), as well as preferences for receiving in-clinic education about CRCS. Eight mixed gender focus groups were conducted with 53 patients. Findings centered on three thematic factors: (1) motivators and impediments to CRCS, (2) test-specific preferences and receptivity to iFOBTs, and (3) preferences for entertaining and engaging plain language materials. Results informed the development of educational priming materials to increase CRCS using iFOBT in FQHCs. PMID:25249181

    During system level testing intermittent and permanent open circuit failures of mated, crimp removable, electrical contact pairs were experienced. The root cause of the failures was determined to be low (but not zero) contact forces applied by the socket contact tines against the engaging pin. The low contact force reduces the effectiveness of the wiping action of the socket tines against the pin. The observed failure mode may be produced when insufficient wiping during mate, demate and small relative movement in use allows for the accumulation of debris or insulating films that electrically separate the contact pair. The investigation identified at least three manufacturing process control problems associated with the socket contacts that enabled shipment of contacts susceptible to developing low contact forces: (1) Improper heat treatment of the socket tines resulting in plastic rather than elastic behavior; (2) Overly thinned socket tines at their base resulting in reduced pin retention forces; (3) insufficient screening tests to identify parts susceptible to the aforementioned failure mechanisms. The results from an extensive screening program of socket contacts utilizing the industry standard contact separation force test procedures are described herein. The investigation shows this method to be capable of identifying initially weak sockets. However, sockets whose contact retention forces may degrade during use may not be screened out by pin retention testing alone. Further investigations are required to correlate low contact retention forces with increased electrical contact resistance in the presence of insulating films that may accumulate in the use environment.

    Health-related quality of life (HRQL) is a central concept for understanding the outcomes of medical care. When used in cost-effectiveness analysis, HRQL is typically measured for conditions persisting over long time frames (years), and quality-adjusted life year (QALY) values are generated. Consequently, years are the basic unit of time for cost-effectiveness analysis results: dollars spent per QALY gained. However, shorter term components of health care may also affect HRQL, and there is increased interest in measuring and accounting for these events. In radiology, the short-term HRQL effects of screening and diagnostic testing may affect a test's cost-effectiveness, even though they may only last for days. The unique challenge in radiology HRQL assessment is to realistically tap into the testing and screening experience while remaining consistent with QALY theory. The authors review HRQL assessment and highlight methods developed to specifically address the short-term effects of radiologic screening and testing. PMID:19643385

    The screening and testing program the US Environmental Protection Agency (EPA) is currently developing to detect endocrine-disrupting chemicals (EDCs) is described. EDCs have been shown to alter the following activities: hypothalamic-pituitary-gonadal (HPG) function; estrogen, androgen, and thyroid hormone synthesis; and androgen and estrogen receptor-mediated effects in mammals and other animals. The value and limitations of mammalian in vivo assays are described that involve the use of the laboratory rat, the EPA Endocrine Disruptor Screening and Testing Advisory Committee species of choice. The discussion includes the evaluation of high-priority chemicals positive in the Tier 1 Screening (T1S) battery, and of subsequent testing in the Tier 2 (T2) battery, with additional short-term screening assays proposed for use in T1.5 to eliminate any uncertainty about T1S results. Descriptions include the in vivo uterotropic assay, which detects estrogens and antiestrogens; the pubertal female assay, which assesses steroidogenesis, antithyroid activity, antiestrogenicity, and HPG function; and the Hershberger assay, which detects the weight of androgen-dependent tissues in castrate-immature-male rats (antiandrogens). Of the several alternative mammalian in vivo assays proposed, a short-term pubertal male rat assay appears most promising for inclusion in T1 or T1.5. An additional in utero-lactational screening protocol is being evaluated, but appears to be better suited for T1.5 or T2 due to the size, complexity, and duration of the assay. The adult intact male assay, also proposed as an alternative for T1, attempts to identify EDCs in a hormonal battery, but has limited value as a screen due to lack of sensitivity and specificity. For Tier 2 testing, the number of endocrine-sensitive endpoints and offspring (F1) examined in multigenerational tests must be thoughtfully expanded for EDCs on a mode-of-action-specific basis, with consideration given to tailoring T2 based on

    Purpose To compare four stereo tests (Lang I, Lang II, Titmus, and TNO) and assess their effectiveness. The main focus of this study is to identify the most useful stereo test as a challenging tool in the screening of strabismus. Patients and methods A total of 143 Caucasian subjects, 74 males (52%) and 69 females (48%), aged between 4 years and 78 years (mean age 19.09±15.12 years) were examined at our Strabismus Service (Scientific Institute San Raffaele Hospital, Milan, Italy) and included in this observational cross-sectional study. Subjects recruited in this study were either affected by strabismus, including microstrabismic patients, or healthy volunteers. Subjects affected by ophthalmological diseases, other than strabismus, were excluded. All patients underwent both ophthalmological and orthoptic examination, including stereo tests, Hirschberg Corneal Light Reflex Test, Worth Four-Dot Test, the 4 Prism Diopter Base-Out Test, Cover Testing, Bruckner Test, visual acuity, automated refraction under 1% tropicamide cycloplegia and thereafter, posterior pole evaluation. Results All data were processed using the IBM SPSS Statistics, Version 2.0, to perform all statistical calculations. The main finding of this study is that Lang I stereo test achieved the highest sensitivity (89.8%) and specificity (95.2%) in detecting strabismus, including microstrabismus as well, compared to all the other stereoacuity tests. Furthermore, Lang I is the stereo test with the highest positive predictive value and negative predictive value, both greater than 90%. Conclusion The stereo test with the highest sensitivity, specificity, positive predictive value, and negative predictive value is Lang I. These results suggest its applicability as a screening test for strabismus in people older than 4 years. PMID:25419114

    The results from the screening toxicity tests Artemia salina, Microtox{reg_sign}, and Mitochondria RET test were compared with those obtained from OSPAR (Oslo and Paris Commissions)-authorized procedures for testing of offshore chemicals (Skeletonema costatum, Acartia tonsa, Abra alba, and Corophium volutator). In this study 82 test substances (26 non-water soluble) were included. The Microtox test was found to be the most sensitive of the three screening tests. Microtox and Mitochondria RET test results showed good correlation with results from Acartia and Skeletonema testing, and it was concluded that the Microtox test was a suitable screening test as a base for assessment of further testing, especially regarding water-soluble chemicals. Sensitivity of Artemia salina to the tested chemicals was too low for it to be an appropriate bioassay organism for screening testing. A very good correlation was found between the results obtained with the Skeletonema and Acartia tests. The results indicated no need for more than one of the Skeletonema or Acartia tests if the Skeletonema median effective concentration or Acartia median lethal concentration was greater than 200 mg/L. The sediment-reworker tests (A. Alba or C. volutator) for chemicals that are likely to end up in the sediments (non-water soluble or surfactants) should be performed, independent of results from screening tests and other OSPAR species.

    Conventional multi-layer insulations exhibit excellent insulation performance but they are limited to the temperature range to which their components reflective foils and spacer materials are compatible. For high temperature applications, the internal multi-screen insulation IMI has been developed that utilizes unique ceramic material technology to produce reflective screens with high temperature stability. For analytical insulation sizing a parametric material model is developed that includes the main contributors for heat flow which are radiation and conduction. The adaptation of model-parameters based on effective steady-state thermal conductivity measurements performed at NASA Langley Research Center (LaRC) allows for extrapolation to arbitrary stack configurations and temperature ranges beyond the ones that were covered in the conductivity measurements. Experimental validation of the parametric material model was performed during the thermal qualification test of the X-38 Chin-panel, where test results and predictions showed a good agreement.

    Four crude oils (H Coal-Fuel Oil Mode, Occidental in situ Shale Oil, Exxon Donor Solvent Liquid, and SRC II) which were distilled into four fractions (naphtha, mid-distillate, gas oil and residue) for analysis and biological screening testing during the last report period were tested for mutagenicity by the Ames test and for tumor initiating activity by an initiation/promotion (skin painting) test. Substantial agreement exists between Ames and skin painting results. Low boiling naphtha fractions of the 4 crude oils showed little or no mutagenicity or tumor initiating activity by the two tests used. The higher boiling fractions (gas oils and residues) and the crude oils themselves were mutagenic and exhibited tumor initiation activity. The coal derived fractions were more active by both tests than the shale oil fractions.

    Background Screening guidelines are used to help identify prediabetes and diabetes before implementing evidence-based prevention and treatment interventions. We examined screening practices benchmarking against two US guidelines, and the capacity of each guideline to identify dysglycemia. Methods Using 2007–2012 National Health and Nutrition Examination Surveys, we analyzed nationally-representative, cross-sectional data from 5,813 fasting non-pregnant adults aged ≥20 years without self-reported diabetes. We examined proportions of adults eligible for diagnostic glucose testing and those who self-reported receiving testing in the past three years, as recommended by the American Diabetes Association (ADA) and the US Preventive Services Task Force (USPSTF-2008) guidelines. For each screening guideline, we also assessed sensitivity, specificity, and positive (PPV) and negative predictive values in identifying dysglycemia (defined as fasting plasma glucose ≥100 mg/dl or hemoglobin A1c ≥5.7%). Results In 2007–2012, 73.0% and 23.7% of US adults without diagnosed diabetes met ADA and USPSTF-2008 criteria for screening, respectively; and 91.5% had at least one major risk factor for diabetes. Of those ADA- or USPSTF-eligible adults, about 51% reported being tested within the past three years. Eligible individuals not tested were more likely to be lower educated, poorer, uninsured, or have no usual place of care compared to tested eligible adults. Among adults with ≥1 major risk factor, 45.7% reported being tested, and dysglycemia yields (i.e., PPV) ranged from 45.8% (high-risk ethnicity) to 72.6% (self-reported prediabetes). ADA criteria and having any risk factor were more sensitive than the USPSTF-2008 guideline (88.8–97.7% vs. 31.0%) but less specific (13.5–39.7% vs. 82.1%) in recommending glucose testing, resulting in lower PPVs (47.7–54.4% vs. 58.4%). Conclusion Diverging recommendations and variable performance of different guidelines may be impeding

    Faecal immunochemical tests (FITs) and colonoscopy are two common screening tools for colorectal cancer(CRC). Most cost-effectiveness studies focused on survival as the outcome, and were based on modeling techniques instead of real world observational data. This study evaluated the cost-effectiveness of these two tests to detect colorectal neoplastic lesions based on data from a 5-year community screening service. The incremental cost-effectiveness ratio (ICER) was assessed based on the detection rates of neoplastic lesions, and costs including screening compliance, polypectomy, colonoscopy complications, and staging of CRC detected. A total of 5,863 patients received yearly FIT and 4,869 received colonoscopy. Compared with FIT, colonoscopy detected notably more adenomas (23.6% vs. 1.6%) and advanced lesions or cancer (4.2% vs. 1.2%). Using FIT as control, the ICER of screening colonoscopy in detecting adenoma, advanced adenoma, CRC and a composite endpoint of either advanced adenoma or stage I CRC was US$3,489, US$27,962, US$922,762 and US$23,981 respectively. The respective ICER was US$3,597, US$439,513, -US$2,765,876 and US$32,297 among lower-risk subjects; whilst the corresponding figure was US$3,153, US$14,852, US$184,162 and US$13,919 among higher-risk subjects. When compared to FIT, colonoscopy is considered cost-effective for screening adenoma, advanced neoplasia, and a composite endpoint of advanced neoplasia or stage I CRC. PMID:26338314

    19 terms and concepts from evaluations of competency to stand trial of 55 defendants with mental retardation were rated to examine whether a quick screening test could be devised that would differentiate those who were judged competent or not competent. A multiple regression and discriminant analysis gave four items that yielded maximum predictability (R = .84): court strategy, plead, testify, and jury. Guilty, trial, and prosecutor were also significantly more difficult for those who were not competent than those who were. PMID:7770598

    We present correlating expressions, in terms of Reynolds or Peclet numbers, for friction factors, Nusselt numbers, enhanced axial conduction ratios, and overall heat flux ratios in four porous regenerator samples representative of stirling cycle regenerators: two woven screen samples and two random wire samples. Error estimates and comparison of data with others suggest our correlations are reliable, but we need to test more samples over a range of porosities before our results will become generally useful.

    We prospectively evaluated the incidence of blood transfusion in 105 consecutively treated patients (45 men and 60 women) having bimaxillary orthognathic operations, to find out whether type and screen testing are adequate in clinical practice. All patients had Le Fort I osteotomy combined with bilateral sagittal split osteotomy of the ramus. The preoperative routine was restricted to type and screen testing and verification of ABO/Rhesus (Rh) status. Autologous blood donation or routine cross-matching of allogeneic units of blood was not done. Intraoperative haemoglobin concentrations and the need for blood transfusion in patients having bimaxillary osteotomies were recorded in a prospective database. The mean duration of operation was 196 min (range 115-325). The median length of hospital stay was 8 days (range 4-16). The mean (SD) reduction in haemoglobin during operation was 34 (16)g/L in men and 32 (10)g/L in women (p=0.32). No patients had an allogeneic blood transfusion. We found that type and screen testing and verification of ABO/Rh status seems to be an adequate precaution to manage blood loss. As reflected by the low rate of transfusion in the present study, severe haemorrhage that requires transfusion of allogeneic blood has become the exception rather than the rule in bimaxillary orthognathic operations.

    The recent introduction of buprenorphine use by the Drug Addiction Services has induced toxicology laboratories to develop new qualitative or semiquantitative screening assay for its determination in hair samples. The aim of this preliminary study was to verify the correlation between the buprenorphine intake and the immunometric screening test results (VMA-T Comedical and buprenorphine CEDIA/Thermo-Fisher/Microgenics reagents) and therefore their comparison with the liquid chromatography coupled with mass spectrometry (LC/MS) results. Hair samples were obtained from 32 subjects without buprenorphine-therapy reported and 17 in treatment. In glass test tube with hermetic cap were weighed 33 mg of 49 finely cut hair samples, washed with 1 mL of SLV-VMA-T washing solution, which is then completely sucked and eliminated. The samples were extracted with 400 microL of VMA-T reagent for an hour at 100 degrees C. The extracts were analysed by immunometric screening test on ILab 650 chemistry analyser, using buprenorphine CEDIA reagent assay. From the 32 non-takers of drug, 30 semiquantitative results were less than 10 pg/mg and 2 were over 10 pg/mg; from the 17 subjects with therapy, all were over 10 pg/mg (range 13-50 pg/mg); no samples were false-negative. Results suggest that exist a good relationship between the administration of buprenorphine and its concentration in hair, detectable through this method and reagents line. PMID:20080369

    The aim was to evaluate human papillomavirus (HPV) ‘reflex genotyping' in cases of minor cytological abnormalities detected in the gynaecological screening programme in Stockholm, Sweden. Liquid-based cytology samples showing minor cytological abnormalities were analysed using HPV genotyping (Linear Array, Roche diagnostics). Colposcopically directed cervical biopsies were obtained and the HPV test results were correlated with the histological results. In all, 63% (70/112) of the samples were high-risk (HR) HPV (HR-HPV) positive. A statistically significant correlation was found between high-grade cervical lesions and HR-HPV (P=0.019), among which HPV 16, 18, and 31 were the most important. The negative predictive value of HR-HPV detection for histologically confirmed high-grade lesions was 100%. An age limit for HPV reflex testing may be motivated in cases of low-grade squamous intraepithelial neoplasia (LSIL), because of high HR-HPV prevalence among younger women. By using HPV reflex genotyping, additional extensive workup can safely be avoided in about 50% of all cases of atypical squamous cells of undetermined significance (ASCUS) and LSIL among women ⩾30 years. This screening strategy could potentially reduce the total abnormal cytology-reporting rate in the Swedish screening programme by about 1% and provide more accurately directed follow-up, guided by cytological appearance and HPV test results.

    Nucleic acid testing (NAT) for hepatitis C virus (HCV) is recommended for screening of organ donors, yet not all donor infections may be detected. We describe three US clusters of HCV transmission from donors at increased risk for HCV infection. Donor's and recipients' medical records were reviewed. Newly infected recipients were interviewed. Donor-derived HCV infection was considered when infection was newly detected after transplantation in recipients of organs from increased risk donors. Stored donor sera and tissue samples were tested for HCV RNA with high-sensitivity quantitative PCR. Posttransplant and pretransplant recipient sera were tested for HCV RNA. Quasispecies analysis of hypervariable region-1 was used to establish genetic relatedness of recipient HCV variants. Each donor had evidence of injection drug use preceding death. Of 12 recipients, 8 were HCV-infected-6 were newly diagnosed posttransplant. HCV RNA was retrospectively detected in stored samples from donor immunologic tissue collected at organ procurement. Phylogenetic analysis showed two clusters of closely related HCV variants from recipients. These investigations identified the first known HCV transmissions from increased risk organ donors with negative NAT screening, indicating very recent donor infection. Recipient informed consent and posttransplant screening for blood-borne pathogens are essential when considering increased risk donors. PMID:25943299

    The Ultra-Vision screen (Du Pont, Towanda, Pa.) contains a yttrium tantalate phosphor-emitting ultraviolet light and eliminates the crossover effect. Increased resolution has been proven in vitro and the purpose of the present study was to test these findings in a clinical situation. Fifteen pairs of skull radiographs were produced with the use of Du Pont Ultra-Vision Rapid screens and Kodak Lanex (Eastman Kodak, Rochester, N.Y.) screens both belonging to speed class 400. Objects were a cadaver head, a 3M phantom head (3M Corp., St. Paul, Minn.), and patients who were serially radiographed as controls in a dental implant study. The radiographs had identical densities, but contrast was varied deliberately. Twelve observers judged the radiographs blindly. Ninety-two percent of the ratings with respect to resolution favored the Ultra-Vision system. However, great doubt was expressed regarding contrast. The agreement between the observers was tested by a Cochran's Q test. The results confirm that the Ultra-Vision system exhibits an improved resolution compared with the Lanex system. Ultra-Vision is recommended whether improved resolution of the radiographs or an expected reduced patient dose is preferred. PMID:8170665

    Objective To describe the intervention development process and feasibility testing of a hospital-based brief intervention to reduce the perpetration of adolescent dating abuse (ADA). To our knowledge, this intervention is the first to focus exclusively on ADA perpetration reduction via a motivational interview-type intervention in this setting. Method The rationale for and the six Intervention Mapping steps used to generate the intervention are described. Feasibility is conceptualized as intervention acceptability, demand, implementation, practicality, integration, and limited-efficacy. Results The Real Talk intervention was integrated smoothly into the emergency department setting. Participants did not experience any negative impact, and the vast majority (86%) reported that they felt helped. Quantitative assessments suggest that the intervention reduced the number of participants in the pre-contemplation stage of change regarding their use of relationship violence, and may have moved them forward into the action stage. Real Talk participants were more likely than those in the control group to tell friends to help them stay calm around their partner after drinking alcohol, and to talk with their doctor to get help for their problems. Conclusions Real Talk was developed to meet an unmet need for tertiary ADA interventions in non-school settings. It was developed in accordance with a recommended framework, informed by theory, and subsequently tested for feasibility. Feasibility assessment results suggest that Real Talk can be implemented in health care settings and may influence attitudinal and behavioral outcomes in the desired directions. PMID:27525169

    The illness of three people due to diarrhetic shellfish poisoning (DSP) following their ingestion of recreationally harvested mussels from Sequim Bay State Park in the summer of 2011, resulted in intensified monitoring for diarrhetic shellfish toxins (DSTs) in Washington State. Rapid testing at remote sites was proposed as a means to provide early warning of DST events in order to protect human health and allow growers to test “pre-harvest” shellfish samples, thereby preventing harvest of toxic product that would later be destroyed or recalled. Tissue homogenates from several shellfish species collected from two sites in Sequim Bay, WA in the summer 2012, as well as other sites throughout Puget Sound, were analyzed using three rapid screening methods: a lateral flow antibody-based test strip (Jellett Rapid Test), an enzyme-linked immunosorbent assay (ELISA) and a protein phosphatase 2A inhibition assay (PP2A). The results were compared to the standard regulatory method of liquid chromatography coupled with tandem mass spectroscopy (LC-MS/MS). The Jellett Rapid Test for DSP gave an unacceptable number of false negatives due to incomplete extraction of DSTs using the manufacturer’s recommended method while the ELISA antibody had low cross-reactivity with dinophysistoxin-1, the major toxin isomer in shellfish from the region. The PP2A test showed the greatest promise as a screening tool for Washington State shellfish harvesters. PMID:24084788

    NASA's extensive efforts towards more efficient, safer, and more affordable space transportation include the development of new thrust-cell liner materials with improved capabilities and longer lives. For rocket engines fueled with liquid hydrogen, an important metric of liner performance is resistance to blanching, a phenomenon of localized wastage by cycles of oxidation-reduction due to local imbalance in the oxygen-fuel ratio. The current liner of the Space Shuttle Main Engine combustion chamber, a Cu-3Ag-0.5Zr alloy (NARloy-Z) is degraded in service by blanching. Heretofore, evaluating a liner material for blanching resistance involved elaborate and expensive hot-fire tests performed on rocket test stands. To simplify that evaluation, researchers at the NASA Glenn Research Center developed a screening test that uses simple, in situ oxidation-reduction cycling in a thermogravimetric analyzer (TGA). The principle behind this test is that resistance to oxidation or to the reduction of oxide, or both, implies resistance to blanching. Using this test as a preliminary tool to screen alloys for blanching resistance can improve reliability and save time and money. In this test a small polished coupon is hung in a TGA furnace at the desired (service) temperature. Oxidizing and reducing gases are introduced cyclically, in programmed amounts. Cycle durations are chosen by calibration, such that all copper oxides formed by oxidation are fully reduced in the next reduction interval. The sample weight is continuously acquired by the TGA as usual.

    Antibiotics are widely used in animal husbandry, and the presence of antibiotic residues in milk is a health hazard. The objectives of this study were to determine residual amounts of oxytetracycline in the milk of three breeds of goats using high-pressure liquid chromatography (HPLC) analysis and screening tests. It was also essential to explore the safe withdrawal period of oxytetracycline in lactating goats and examine the applicability of Charm ROSA and SNAP screening tests. The qualitative results of these tests were compared with the quantitative results of the HPLC method. Fifteen milking does, five each from the Alpine, LaMancha, and Nubian breeds, were selected from the herd at Prairie View A&M University. Milk samples containing antibiotic residues were deproteinized by HCl and acetonitrile, and then oxytetracycline was extracted from the supernatant. The residues of oxytetracycline in goat's milk up to 110 h after injection were qualitatively detected using the Charm ROSA test. Similarly, the SNAP test detected the antibiotic residues in milk up to 110 h after treatment. The HPLC results indicated that oxytetracycline residues in milk from Alpine goats were below the tolerance level (300 ng/ml) 82 h after drug treatment (72 h for LaManchas, 58 h for Nubians); however, the results of the screening tests would indicate longer withdrawal periods for milk from the breeds of goats studied, which would result in economic losses to goat's milk producers. The results of this study also indicated that oxytetracycline was not stable in raw goat's milk at refrigeration temperature or during pasteurization and that the concentrations decreased significantly. Commercial goat's milk is usually exposed to several hours of refrigeration and then to pasteurization. The results of this study indicated that, if oxytetracycline was present in raw goat's milk, the concentration would decrease significantly before it was marketed. PMID:27296606

    Although, it is well-established that information on the metabolism of a substance is important in the evaluation of its toxic potential, there is limited experience with incorporating metabolic aspects into in vitro tests for endocrine disrupters. The aim of the current study was a) to study different in vitro systems for biotransformation of ten known endocrine disrupting chemicals (EDs): five azole fungicides, three parabens and 2 phthalates, b) to determine possible changes in the ability of the EDs to bind and activate the thyroid receptor (TR) in the in vitro T-screen assay after biotransformation and c) to investigate the endogenous metabolic capacity of the GH3 cells, the cell line used in the T-screen assay, which is a proliferation assay used for the in vitro detection of agonistic and antagonistic properties of compounds at the level of the TR. The two in vitro metabolizing systems tested the human liver S9 mix and the PCB-induced rat microsomes gave an almost complete metabolic transformation of the tested parabens and phthalates. No marked difference the effects in the T-screen assay was observed between the parent compounds and the effects of the tested metabolic extracts. The GH3 cells themselves significantly metabolized the two tested phthalates dimethyl phthalate (DMP) and diethyl phthalate (DEP). Overall the results and qualitative data from the current study show that an in vitro metabolizing system using liver S9 or microsomes could be a convenient method for the incorporation of metabolic and toxicokinetic aspects into in vitro testing for endocrine disrupting effects.

Microcrystalline tests are shown to be non-destructive as addition products formed were easily dissociated after the application of an appropriate solvent. Subsequent analysis of the sample was done to quantify the recovery of the drug. Examples were performed using the date rape drug γ-hydroxybutyrate (GHB) and the synthetic opioid methadone.

    Non-accidental injury (NAI) is a major medical concern in the United States. One of the challenges in evaluation of children with unexplained fractures is that genetic forms of bone fragility are one of the differential diagnoses. Infants who present with fractures with mild forms of osteogenesis imperfecta (OI) (OI type I or OI type IV), the most common genetic form of bone disease leading to fractures might be missed if clinical evaluation alone is used to make the diagnosis. Diagnostic clinical features (blue sclera, dentinogenesis imperfecta, Wormian bones on X-rays or positive family history) may not be present or apparent at the age of evaluation. The evaluating clinician faces the decision about whether genetic testing is necessary in certain NAI cases. In this review, we outline clinical presentations of mild OI and review the history of genetic testing for OI in the NAI versus OI setting. We summarize our data of molecular testing in the Collagen Diagnostic Laboratory (CDL) from 2008 to 2014 where NAI was noted on the request for DNA sequencing of COL1A1 and COL1A2. We provide recommendations for molecular testing in the NAI versus OI setting. First, DNA sequencing of COL1A1, COL1A2, and IFITM5 simultaneously and duplication/deletion testing is recommended. If a causative variant is not identified, in the absence of a pathologic clinical phenotype, no additional gene testing is indicated. If a VUS is found, parental segregation studies are recommended.

    Objective: Drugs can influence results of multiple sleep latency tests (MSLT). We sought to identify the effect of marijuana on MSLT results in pediatric patients evaluated for excessive daytime sleepiness (EDS). Methods: This is a retrospective study of urine drug screens performed the morning before MSLT in 383 patients < 21 years old referred for EDS. MSLT results were divided into those with (1) (−) urine drug screens, (2) urine drug screens (+) for tetrahydrocannabinol (THC) alone or THC plus other drugs, and (3) urine drug screens (+) for drugs other than THC. Groups were compared with Fisher exact tests or one-way ANOVA. Results: 38 (10%) urine drug tests were (+): 14 for THC and 24 for other drugs. Forty-three percent of patients with drug screen (+) for THC had MSLT findings consistent with narcolepsy, 0% consistent with idiopathic hypersomnia, 29% other, and 29% normal. This was statistically different from those with (−) screens (24% narcolepsy, 20% idiopathic hypersomnia, 6% other, 50% normal), and those (+) for drugs other than THC (17% narcolepsy, 33% idiopathic hypersomnia, 4% other, 46% normal (p = 0.01). Six percent (6/93) of patients with MSLT findings consistent with narcolepsy were drug screen (+) for THC; 71% of patients with drug screen (+) for THC had multiple sleep onset REM periods (SOREMS). There were no (+) urine drug screens in patients < 13 years old. Conclusion: Many pediatric patients with (+) urine drug screens for THC met MSLT criteria for narcolepsy or had multiple SOREMs. Drug screening is important in interpreting MSLT findings for children ≥ 13 years.

    We present experimental results for room temperature bubble point tests conducted at the Cedar Creek Road Cryogenic Complex, Cell 7 (CCL-7) at the NASA Glenn Research Center. The purpose of these tests was to investigate the performance of three different fine mesh screens in room temperature liquids to provide pretest predictions in cryogenic liquid nitrogen (LN2) and hydrogen (LH2) as part of NASA's microgravity LAD technology development program. Bench type tests based on the maximum bubble point method were conducted for a 325 x 2300, 450 x 2750, and 510 x 3600 mesh sample in pure room temperature liquid methanol, acetone, isopropyl alcohol, water, and mixtures of methanol and water to cover the intermediate to upper surface tension range. A theoretical model for the bubble point pressure is derived from the Young-LaPlace equation for the pressure drop across a curved interface. Governing equations are reduced in complexity through a set of simplifying assumptions to permit direct comparison with the experimental data. Screen pore sizes are estimated from scanning electron microscopy (SEM) to make pretest predictions. Pore sizes based on SEM analysis are compared with historical data available in the literature for the 325 x 2300 and 450 x 2750 screens as well with data obtained from bubble point tests conducted in this work. Experimental results show that bubble point pressure is proportional to the surface tension of the liquid. We show that there is excellent agreement between data and model for pure fluids when the data is corrected for non-zero contact angle measured on the screens using a modified Sessile Drop technique. SEM image analysis of the three meshes indicated that bubble point pressure would be a maximum for the finest mesh screen. The pore diameters based on SEM analysis and experimental data obtained here are in excellent agreement for the 325 x 2300 and 450 x 2750 meshes, but not for the finest 510 x 3600 mesh. Therefore the simplified model

    Standard oxide-stripe defined GaAs(GaAl)As lasers were aged at room temperature at high CW power (20 mW); the current was increased during aging to maintain this output level and the lasers were considered dead when they could no longer produce 20 mW, regardless of current. The laser lifetime data were subjected to a simple screening test to identify the longer lived units. The effect this test has on the lifetime distribution and on the reliability of a system composed of a set of these lasers is considered.

  15. New strategies for blood donor screening for hepatitis B virus: nucleic acid testing versus immunoassay methods.

    Serologic testing for hepatitis B virus (HBV) surface antigen (HBsAg) and antibody to HBV core antigen (anti-HBc) has historically been the foundation of blood screening, while HBV nucleic acid testing (NAT) was recently developed to detect HBsAg-negative, anti-HBc-negative blood units donated during early acute infection. Comparison data on seroconversion panels using HBsAg assays of varying sensitivities and pooled- or single-sample NAT, along with viral load estimates corresponding to HBsAg assay detection limits, have provided information on the theoretical benefits of NAT relative to HBsAg. Model-derived estimates have generally been predictive of the yields of DNA-positive, HBsAg-negative window period blood units detected in a number of studies from Europe, Japan, and the US. Studies indicate that the added benefit of pooled-sample NAT is relatively small in areas of low endemicity, with greater yields in areas highly endemic for HBV. Single-sample NAT would offer more significant early window period closure and could prevent a moderate number of residual HBV transmissions not detected by HBsAg assays; however, no fully automated single-sample HBV NAT systems are currently available.Even single-sample HBV NAT may not substitute for anti-HBc screening, as indicated by studies of donors with isolated anti-HBc who have extremely low DNA levels undetectable by standard single-sample NAT and who have been associated with transfusion-transmitted HBV. Moreover, HBsAg testing may still be needed even in the setting of combined anti-HBc and NAT screening. HBsAg-positive units from donors in the chronic stage of infection may contain very low or intermittently detectable DNA levels that single-sample NAT would miss. Although such donors are usually anti-HBc reactive and would be interdicted by anti-HBc screening, some lack anti-HBc. Extensive parallel testing will be needed to determine whether single-sample NAT in combination with anti-HBc might be sufficient to

    Juvenile offenders are a subgroup of adolescents at particular risk for HIV/STI infection. Although HIV prevalence among these youth is low (<1%) in the US, rates of other STIs, unprotected sexual activity, multiple partners, and incidents of substance use during sex are high compared with other adolescent populations. Many of these youth will enter the adult criminal justice system, which is known to have an extremely high rate of HIV infection. US constitutional mandates provide HIV/STI testing for incarcerated juveniles, but close to 80% of juvenile arrestees are never detained. Moreover, although they engage in similar HIV risk behaviors as those detained, they have limited access to available HIV/STI testing services. Thus, our study examined rates of lifetime HIV testing among a pilot sample of 60 court-involved, substance-using juveniles monitored in the community to explore rates of testing and the reasons related to lifetime testing among a high-risk, yet understudied US juvenile population.

    Background The incidence of Down syndrome (DS) in Egypt varies between 1∶555 and 1∶770 and its screening by triple test is becoming increasingly popular nowadays. Results, however, seem inaccurate due to the lack of Egyptian-specific information needed for risk calculation and a clear policy for programme implementation. Our study aimed at calculation and validation of the triple marker medians used in screening Egyptian females as well as to recommend programme conventions to unify screening in this country. Methods The study was conducted on 668 Egyptian women, in weeks 15–20 of pregnancy as proven by sonar. Chorionic gonadotropin (CG), α-fetoprotein (AFP) and unconjugated oestriol (uE3) were measured on Siemens Immulite analyzer. Medians of the three parameters were calculated, regressed against gestational age (GA) and weighted by the number of participants/week. Equations were derived to adjust each parameter to the maternal weight and were centered on the median Egyptian weight. Prisca software was fed with the above data, multiples-of-median (MoM) and DS risks were calculated and the screening performance was evaluated at a mid-trimester risk cutoff of 1∶270. Results Log-linear [AFP/uE3 = 10(A+B*GA)] and exponential equations [CG = A*e (B*GA)] were derived and the regressed medians were found to follow similar patterns to other Asian and Western medians. Oestriol was always lowest (even halved) while CG and AFP were intermediate. A linear reciprocal model best fitted weight distribution among Egyptians and successfully adjusted each parameter to a weight of 78.2 kg. Epidemiological monitoring of these recommendations revealed satisfactory performance in terms of 6.7% initial positive rate and 1.00 grand MoM. Conclusions Adoption of the above recommendations is hoped to pave the way to a successful DS screening programme tailored to Egyptian peculiarities. PMID:25330176

    To identify Chinese geneticists' views of ethical issues in genetic testing and screening, a national survey was conducted. Of 402 Chinese geneticists asked to participate, 255 (63%) returned by mail anonymous questionnaires. The majority of respondents thought that genetic testing should be offered in the workplace for alpha-antitrypsin deficiency (95%) and the predisposition of executives to heart disease, cancer, and diabetes (94%); that genetic testing should be included in preemployment physical examinations (86%); that governments should require premarital carrier tests (86%), newborn screening for sickle cell (77%), and Duchenne muscular dystrophy (71%); and that children should be tested for genes for late-onset disorders such as Huntington disease (85%), susceptibility to cancers (85%), familial hypercholesterolemia (84%), alcoholism (69%), and Alzheimer disease (61%). Most believed that partners should know each other's genetic status before marriage (92%), that carriers of the same defective gene should not mate with each other (91%), and that women should have a prenatal diagnosis if medically indicated (91%). The majority said that in China decisions about family planning were shared by the couple (82%). More than half had views that, in China, there were no laws to prohibit disability discrimination (64%), particularly to protect people with adult polycystic kidney disease (57%), cystic fibrosis (56%), or genetic predisposition to other diseases (50%). To some extent, these results might provide a basis for a discussion of eugenics in China, particularly about China's Maternal and Infant Health Care Law (1994). PMID:9718350

    Background: Abnormal levels of the markers AFP, hCG, and uE3 could be useful in predicting adverse pregnancy outcomes. This study was designed to determine the correlation between second trimester maternal serum markers and adverse pregnancy outcome (APO). Methods: In this historical cohort study, we randomly followed 231 obstetric patients with quadruple screening test in 14-18 weeks of gestation from March 2012 to March 2013 in a medical laboratory in Babol, Iran. We measured maternal serum levels of alphafetoprotein (AFP), human chorionic gonadotropin (hCG), unconjugated estriol (uE3), and inhibin-A. The risk of adverse pregnancy outcomes (APOs) were then compared between patients with negative and positive test results. We used Chi-square and Fisher-exact tests for qualitative variables and t-test for quantitative variables. Demographic differences between the two groups were minimized by applying logistic regression. Results: The risk of having an APO such as pre-eclampsia (p=0.008), fetal growth restriction (p=0.028) and premature rupture of membrane (p=0.040) increased significantly in patients with abnormal markers. Conclusion: Abnormal results of quadruple screening test could be associated with APO in women with normal appearing fetus. PMID:26913244
