This report documents a journey "from research to an approved standard" of a NIST-led standard development activity. That standard, Core Manufacturing Simulation Data (CMSD) information model, provides neutral structures for the efficient exchange of manufacturing data in a simulation environment. The model was standardized under the auspices of the international Simulation Interoperability Standards Organization (SISO). NIST started the research in 2001 and initiated the standardization effort in 2004. The CMSD standard was published in two SISO Products. In the first Product, the information model was defined in the Unified Modeling Language (UML) and published in 2010 as SISO-STD-008-2010. In the second Product, the information model was defined in Extensible Markup Language (XML) and published in 2013 as SISO-STD-008-01-2012. Both SISO-STD-008-2010 and SISO-STD-008-01-2012 are intended to be used together.

Background Sexually transmitted disease (STD) prevention remains a public health priority. Simple, practical interventions to reduce STD incidence that can be easily and inexpensively administered in high-volume clinical settings are needed. We evaluated whether a brief video, which contained STD prevention messages targeted to all patients in the waiting room, reduced acquisition of new infections after that clinic visit. Methods and Findings In a controlled trial among patients attending three publicly funded STD clinics (one in each of three US cities) from December 2003 to August 2005, all patients (n = 38,635) were systematically assigned to either a theory-based 23-min video depicting couples overcoming barriers to safer sexual behaviors, or the standard waiting room environment. Condition assignment alternated every 4 wk and was determined by which condition (intervention or control) was in place in the clinic waiting room during the patient's first visit within the study period. An intent-to-treat analysis was used to compare STD incidence between intervention and control patients. The primary endpoint was time to diagnosis of incident laboratory-confirmed infections (gonorrhea, chlamydia, trichomoniasis, syphilis, and HIV), as identified through review of medical records and county STD surveillance registries. During 14.8 mo (average) of follow-up, 2,042 patients (5.3%) were diagnosed with incident STD (4.9%, intervention condition; 5.7%, control condition). In survival analysis, patients assigned to the intervention condition had significantly fewer STDs compared with the control condition (hazard ratio [HR], 0.91; 95% confidence interval [CI], 0.84 to 0.99). Conclusions Showing a brief video in STD clinic waiting rooms reduced new infections nearly 10% overall in three clinics. This simple, low-intensity intervention may be appropriate for adoption by clinics that serve similar patient populations. Trial registration: http://www.ClinicalTrials.gov (#NCT00137670).

Show me the money: state contributions toward STD prevention, 2007.

The importance of state investment in sexually transmitted disease (STD) prevention has been discussed since the mid-1990s; however, little has become known about state public health funding for STD prevention. To establish a baseline understanding of state STD prevention funding, financial data for fiscal year 2007 were gathered by survey of state STD, immunization, laboratory, and hepatitis program directors. Results revealed that on average states funded 25.8 percent of their total STD prevention budgets and invested $0.23 per capita in STD prevention. The percentage of state funding in the total state STD prevention budget ranged from 0 percent to 70.2 percent, and state investment in STD prevention ranged from $0.00 to $1.55 per capita. The direction and expenditure of state STD prevention resources was also examined. This study strengthens the national understanding of what states are doing to fund STD prevention, and it broadens state public health awareness of the overall STD prevention investment at the state level. The inclusion of Medicaid data and expenditure of federal resources by states would strengthen the study and assist longitudinal analyses focused on the impact of investment on epidemiologic indicators.

STD infection among adolescents is a significant public health concern. Surveys indicate that parents believe STD and HIV/AIDS are appropriate topics for middle school and high school students; however, school-based STD education efforts remain inconsistent, perhaps in part as a result of the lack of standardized, well-distributed curricula.…

Regulation of the Salmonella enterica std fimbrial operon by DNA adenine methylation, SeqA, and HdfR.

PubMed

Jakomin, Marcello; Chessa, Daniela; Bäumler, Andreas J; Casadesús, Josep

2008-11-01

DNA adenine methylase (dam) mutants of Salmonella enterica serovar Typhimurium grown under laboratory conditions express the std fimbrial operon, which is tightly repressed in the wild type. Here, we show that uncontrolled production of Std fimbriae in S. enterica serovar Typhimurium dam mutants contributes to attenuation in mice, as indicated by the observation that an stdA dam strain is more competitive than a dam strain upon oral infection. Dam methylation appears to regulate std transcription, rather than std mRNA stability or turnover. A genetic screen for std regulators showed that the GATC-binding protein SeqA directly or indirectly represses std expression, while the poorly characterized yifA gene product serves as an std activator. YifA encodes a putative LysR-like protein and has been renamed HdfR, like its Escherichia coli homolog. Activation of std expression by HdfR is observed only in dam and seqA backgrounds. These data suggest that HdfR directly or indirectly activates std transcription. Since SeqA is unable to bind nonmethylated DNA, it is possible that std operon derepression in dam and seqA mutants may result from unconstrained HdfR-mediated activation of std transcription. Derepression of std in dam and seqA mutants of S. enterica occurs in only a fraction of the bacterial population, suggesting the occurrence of either bistable expression or phase variation.

Association Between Sexually Transmitted Diseases and Young Adults' Self-reported Abstinence

OBJECTIVE: Self-reported behavior has been the cornerstone of sexual health research and clinical practice, yet advances in sexually transmitted disease (STD) screening provide researchers with the opportunity to objectively quantify sexual risk behaviors. However, the extent to which young adults' laboratory-confirmed STD results and self-reported sexual behaviors are consistent has not been assessed in a nationally representative sample. PATIENTS AND METHODS: Data are derived from participants who completed wave 3 in the National Longitudinal Study of Adolescent Health. Young adults (N = 14 012) completed an audio computer-assisted self-interviewing survey and provided a urine specimen to detect the presence of Chlamydia trachomatis and Neisseria gonorrhoeae, and a polymerase chain reaction assay to detect Trichomonas vaginalis. RESULTS: More than 10% of young adults with a laboratory-confirmed positive STD result reported abstaining from sexual intercourse in the 12 months before assessment and STD testing. After controlling for several sociodemographic factors, self-reported sex (versus those who reported abstinence) in the previous 12 months was significantly associated with testing positive, but the odds of testing positive were only slightly more than twofold (adjusted odds ratio: 2.11 [95% confidence interval: 2.097–2.122]). CONCLUSIONS: Findings indicate discrepancy between young adults' positive STD status and self-reported sexual behavior. No significant correlates of discrepant reporting were identified. From a clinical standpoint, the discrepancies between STD positivity and self-reported sexual behavior observed in this nationally representative sample suggest that routine STD screening may be beneficial and necessary to reduce STD morbidity among young adults.

Interventions for upgrading sexually transmitted disease (STD) management in sub-Saharan Africa have focused on the public sector, and to a much lower extent on private medical practitioners and pharmacies. However, in most African cities there is a large informal sector that provides care to many patients with STD symptoms. To compare the quality of treatments offered to patients with major STD syndromes in the public sector, pharmacies, and the informal sector of the same city. Healthcare providers in health centers, pharmacies, private laboratories, and market drug peddlers in Bangui, Central African Republic, were asked to complete a short form for every patient consulting them with genital complaints. The treatments they ordered were evaluated for their potential efficacy against the major etiologic agents of the syndrome for which the patient consulted. The majority of male patients with STDs preferred to seek care in pharmacies and in the informal sector. The STD treatments offered to patients with urethral discharge or genital ulcers in pharmacies and in the informal sector tended to focus on a single etiologic agent. The quality of STD treatments offered by drug peddlers and private laboratories was poor, apart from adequate coverage of syphilis in patients with genital ulcers and of candidiasis in women with vaginal discharge. For instance, 41% and 34% of patients with urethral discharge managed by drug peddlers and private laboratories did not receive a drug active against either Neisseria gonorrhoeae or Chlamydia trachomatis, whereas this proportion was 22% in pharmacies and 14% in health centers. For patients with genital ulcers, the proportion offered a drug active against Haemophilus ducreyi was 2% if seen by drug peddlers, 0% in laboratories, 10% in pharmacies, and 25% in health centers. For each syndrome and each category of provider, between one fourth and two thirds of patients had already received another ineffective treatment elsewhere. National STD and HIV control programs will have to improve STD management in pharmacies and in the informal sector if they are to have any impact on the dynamics of HIV infection in urban centers.

NASA-STD 3001 and the Human Integration Design Handbook (HIDH): Evolution of NASA-STD-3000

NASA Technical Reports Server (NTRS)

Pickett, Lynn; Connolly, Janis; Arch, M.; Tillman, Barry; Russo, Dane

2007-01-01

The Habitability & Environmental Factors and Space Medicine Divisions have developed the Space Flight Human System Standard (SFHSS) (NASA-STD-3001) to replace NASA-STD-3000 as a new NASA standard for all human spaceflight programs. The SFHSS is composed of 2 volumes. Volume 1, Crew Health, contains medical levels of care, permissible exposure limits, and fitness for duty criteria, and permissible outcome limits as a means of defining successful operating criteria for the human system. Volume 2, Habitability and Environmental Health, contains environmental, habitability and human factors standards. Development of the Human Integration Design Handbook (HIDH), a companion to the standard, is currently under construction and entails the update and revision of NASA-STD-3000 data. This new handbook will, in the fashion of NASA STD-3000, assist engineers and designers in appropriately applying habitability, environmental and human factors principles to spacecraft design. Organized in a chapter-module-element structure, the HIDH will provide the guidance for the development of requirements, design considerations, lessons learned, example solutions, background research, and assist in the identification of gaps and research needs in the disciplines. Subject matter experts have been and continue to be solicited to participate in the update of the chapters. The purpose is to build the HIDH with the best and latest data, and provide a broad representation from experts in industry, academia, the military and the space program. The handbook and the two standards volumes work together in a unique way to achieve the required level of human-system interface. All new NASA programs will be required to meet Volumes 1 and 2. Volume 2 presents human interface goals in broad, non-verifiable standards. Volume 2 also requires that each new development program prepare a set of program-specific human factors requirements. These program-specific human and environmental factors requirements must be verifiable and tailored to assure the new system meets the Volume 2 standards. Programs will use the HIDH to write their verifiable program-specific requirements.

Predicting HIV/STD risk level and substance use disorders among incarcerated adolescents.

Rowe, Cynthia L; Wang, Wei; Greenbaum, Paul; Liddle, Howard A

2008-12-01

Incarcerated adolescents are among the most vulnerable groups for STD infection, and substance abuse is prevalent in over half of this population. Substance abuse and HIV/STD-associated risk behaviors are closely linked among juvenile justice-involved youth, but it is unclear whether common antecedents explain these different problems. The current study examined predictors of HIV/STD risk level and substance use disorders, and investigated whether family variables added unique predictive variance for these problems among incarcerated youth. The sample included 154 substance-involved youth ages 13 to 17 recruited in detention facilities in Miami and Tampa, FL and was primarily male (82%) and African-American (58%). Using a comprehensive assessment strategy with data obtained from youth report, parent report, and laboratory confirmed STD testing, the results show that delinquency is a consistent predictor of both HIV/STD risk level and substance use disorders, and also that substance use directly predicts HIV/STD risk level among incarcerated adolescents. Consistent with previous research, family conflict is an important predictor of substance use disorders even after controlling for other factors. The results suggest the need for integrated family-based interventions addressing delinquency, substance abuse, and HIV/STD-associated risk factors with juvenile justice-involved adolescents.

Simultaneous multislice diffusion-weighted MRI of the liver: Analysis of different breathing schemes in comparison to standard sequences.

To systematically evaluate image characteristics of simultaneous-multislice (SMS)-accelerated diffusion-weighted imaging (DWI) of the liver using different breathing schemes in comparison to standard sequences. DWI of the liver was performed in 10 healthy volunteers and 12 patients at 1.5T using an SMS-accelerated echo planar imaging sequence performed with respiratory-triggering and free breathing (SMS-RT, SMS-FB). Standard DWI sequences served as reference (STD-RT, STD-FB). Reduction of scan time by SMS-acceleration was measured. Image characteristics of SMS-DWI and STD-DWI with both breathing schemes were analyzed quantitatively (apparent diffusion coefficient [ADC], signal-to-noise ratio [SNR]) and qualitatively (5-point Likert scale, 5 = excellent). Qualitative and quantitative parameters were compared using Friedman test and Dunn-Bonferroni post-hoc method with P-values < 0.05 considered statistically significant. SMS-DWI provided diagnostic image quality in volunteers and patients both with RT and FB with a reduction of scan time of 70% (0:56 vs. 3:20 min in FB). Overall image quality did not significantly differ between FB and RT acquisition in both STD and SMS sequences (median STD-RT 5.0, STD-FB 4.5, SMS-RT: 4.75; SMS-FB: 4.5; P = 0.294). SNR in the right hepatic lobe was comparable between the four tested sequences. ADC values were significantly lower in SMS-DWI compared to STD-DWI irrespective of the breathing scheme (1.2 ± 0.2 × 10(-3) mm(2) /s vs. 1.0 ± 0.2 × 10(-3) mm(2) /s; P < 0.001). SMS-acceleration provides considerable scan time reduction for hepatic DWI with equivalent image quality compared to the STD technique both using RT and FB. Discrepancies in ADC between STD-DWI and SMS-DWI need to be considered when transferring the SMS technique to clinical routine reading. J. MAGN. RESON.

To assess the quality of sexually transmitted disease (STD) case management provided in public and private health facilities in selected areas of Madras, Tamil Nadu, India, in order to make recommendations for improving the quality of care and promote the syndromic approach to STD treatment. Structured observations of consultations for STDs in health care facilities. Scoring of the observations according to standards for history taking, examination, treatment and provision of basic health promotion advice allows evaluation of STD case management. With STD treatment adequacy scored against Indian national guidelines (which recommend aetiologic treatment), history taking, examination and treatment were satisfactory in 76 out of 108 (70%) of observed consultations. However, if STD treatment adequacy is scored with respect to the syndrome approach towards selected STD (male urethritis and non herpetic genital ulcer for both sexes), only 8 out of 81 (10%) of the patients were satisfactory managed. During 32 out of 108 (30%) of the consultations, advice on the use of condoms in order to prevent STD or HIV/AIDS was given. Instructions regarding how to use condoms were offered to seven (6%) patients and condoms were only provided to one patient (1%). Patients were urged to refer their partner(s) for treatment during 29 (27%) of consultations. A criterion of adequate use of the STD consultation for health promotion, requiring both promotion of condoms and encouragement to refer partner(s) for treatment, was met during 13 (12%) of consultations. Monitoring and improving the standards of care at facilities at which STDs are treated have become key roles of STD/HIV/AIDS programmes. The present report suggests that in Madras the activities of medical practitioners who treat STD patients are far from ideal at present. Improvements would involve simplifying existing treatment guidelines by promoting the syndromic approach to STD management, continuing education programmes for health care providers in the public and private sectors and repeat assessments and feedback of the quality of STD care.

Variances and uncertainties of the sample laboratory-to-laboratory variance (S(L)2) and standard deviation (S(L)) associated with an interlaboratory study.

The validation process for an analytical method usually employs an interlaboratory study conducted as a balanced completely randomized model involving a specified number of randomly chosen laboratories, each analyzing a specified number of randomly allocated replicates. For such studies, formulas to obtain approximate unbiased estimates of the variance and uncertainty of the sample laboratory-to-laboratory (lab-to-lab) STD (S(L)) have been developed primarily to account for the uncertainty of S(L) when there is a need to develop an uncertainty budget that includes the uncertainty of S(L). For the sake of completeness on this topic, formulas to estimate the variance and uncertainty of the sample lab-to-lab variance (S(L)2) were also developed. In some cases, it was necessary to derive the formulas based on an approximate distribution for S(L)2.

The business of sexually transmitted disease (STD) prevention and control demands technology that is capable of supporting a wide array of program activities-from the processing of laboratory test results to the complex and confidential process involved in contact investigation. The need for a tool that enables public health officials to successfully manage the complex operations encountered in an STD prevention and control program, and the need to operate in an increasingly poor resource environment, led the Florida Bureau of STD to develop the Patient Reporting Investigation Surveillance Manager. Its unique approach, technical architecture, and sociotechnical philosophy have made this business application successful in real-time monitoring of disease burden for local communities, identification of emerging outbreaks, monitoring and assurance of appropriate treatments, improving access to laboratory data, and improving the quality of data for epidemiologic analysis. Additionally, the effort attempted to create and release a product that promoted the Centers for Disease Control and Prevention's ideas for integration of programs and processes.

1998-06-01

This paper reports on a study undertaken in a rural area of South Africa, to develop a non-laboratory tool to screen for sexually transmitted diseases (STDs) among family planning clients. A cross sectional study was performed of 249 consecutive women attending a family planning service between November and December 1994. A questionnaire was administered, and a clinical examination and laboratory tests conducted. Sociodemographic, clinical, and other non-laboratory variables that were significantly associated with laboratory evidence of infection were combined to produce non-hierarchical scoring systems for three "syndromes": gonococcal and/or chlamydial cervical infection, trichomoniasis, and cervical infection and/or trichomoniasis combined. The sensitivity, specificity, and predictive values of the scoring systems as a screening tool were assessed against the gold standard of laboratory tests. The prevalence of reproductive tract infections among the study participants was as follows: Chlamydia trachomatis 12%, Neisseria gonorrhoeae 3%, Trichomonas vaginalis 18%, and bacterial vaginosis 29%. Although vaginal discharge and other symptoms were frequently reported, symptoms bore no relation to the presence of infection. The following independent associations with gonococcal/chlamydial cervical infection were found: age less than 25 years and cervical mucopus and/or friability. Abnormal discharge on examination, visible inflammatory changes of the cervix (increased redness), no recent travel, and unemployment were associated with trichomoniasis. The combination of trichomonas and/or cervical infection ("STD syndrome") was associated with cervical mucopus/friability, unemployment, lack of financial support, and increased redness of the cervix. Of the three scoring systems developed on the basis of these associations, that of the "STD syndrome" achieved the best performance characteristics as a screening tool, with a sensitivity of 62%, specificity of 74%, and positive predictive value of 48%. STDs are common in a population of rural, sexually active women attending a family planning service. In resource poor settings, non-laboratory screening tools could play some role in identifying and treating infections in these women, especially since the majority would not otherwise have been reached. However, such screening tools cannot be viewed as the only way to identify STDs and should be considered as part of an overall strategy of STD control that includes, for example, good management of symptomatic individuals and their partners.

SU-F-T-629: Effect of Multi-Leaf Collimator (MLC) Width On Plan Quality of Single-Isocenter VMAT Intracranial Stereotactic Radiosurgery for Multiple Metastases

DOE Office of Scientific and Technical Information (OSTI.GOV)

Kraus, J; Thomas, E; Wu, X

2016-06-15

Purpose: Single-isocenter VMAT has been shown able to create high quality plans for complex intracranial multiple metastasis SRS cases. Linacs capable of the technique are typically outfitted with an MLC that consists of a combination of 5 mm and 10 mm leaves (standard) or 2.5 mm and 5 mm leaves (high-definition). In this study, we test the hypothesis that thinner collimator leaves are associated with improved plan quality. Methods: Ten multiple metastasis cases were identified and planned for VMAT SRS using a 10 MV flattening filter free beam. Plans were created for a standard (std) and a high-definition (HD) MLC.more » Published values for leaf transmission factor and dosimetric leaf gap were utilized. All other parameters were invariant. Conformity (plan and individual target), moderate isodose spill (V50%), and low isodose spill (mean brain dose) were selected for analysis. Results: Compared to standard MLC, HD-MLC improved overall plan conformity (median: Paddick CI-HD = 0.83, Paddick CI-std = 0.79; p = 0.004 and median: RTOG CI-HD =1.18, RTOG CI-std =1.24; p = 0.01 ), improved individual lesion conformity (median: Paddick CI-HD,i =0.77, Paddick CI-std,i =0.72; p < 0.001 and median: RTOG CI-HD,i = 1.28, RTOG CI-std,i =1.35; p < 0.001), improved moderate isodose spill (median: V50%-HD = 37.0 cc, V50%-std = 45.7 cc; p = 0.002), and improved low dose spill (median: dmean-HD = 2.90 Gy, dmean-std = 3.19 Gy; p = 0.002). Conclusion: For the single-isocenter VMAT SRS of multiple metastasis plans examined, use of HD-MLC modestly improved conformity, moderate isodose, and low isodose spill compared to standard MLC. However, in all cases we were able to generate clinically acceptable plans with the standard MLC. More work is need to further quantify the difference in cases with higher numbers of small targets and to better understand any potential clinical significance.

Aim To evaluate in a rat animal model whether ovariectomy, high fat diet (HFD), and physical activity in the form of running affect leptin receptor (Ob-R) distribution in the brain and white fat tissue compared to sham (Sh) surgery, standard diet (StD), and sedentary conditions. Methods The study included 48 female laboratory Wistar rats (4 weeks old). Following eight weeks of feeding with standard or HFD, rats were subjected to either OVX or Sh surgery. After surgery, all animals continued StD or HFD for the next 10 weeks. During these 10 weeks, ovariectomy and Sh groups were subjected to physical activity or sedentary conditions. Free-floating immunohistochemistry and Western blot methods were carried out to detect Ob-R in the brain and adipose tissue. Results StD-ovariectomy-sedentary group had a greater number of Ob-R positive neurons in lateral hypothalamic nuclei than StD-Sh-sedentary group. There was no difference in Ob-R positive neurons in arcuatus nuclei between all groups. Ob-R distribution in the barrel cortex was higher in HFD group than in StD group. Ob-R presence in perirenal and subcutaneous fat was decreased in StD-ovariectomy group. Conclusion HFD and ovariectomy increased Ob-R distribution in lateral hypothalamic nuclei, but there was no effect on arcuatus nuclei. Our results are first to suggest that HFD, ovariectomy, and physical activity affect Ob-R distribution in the barrel cortex, which might be correlated with the role of Ob-R in election of food in rats.

A study was undertaken in a Cape Town public sector STD clinic to evaluate the content and quality of care provided since it has been recognized that appropriate improvements in the management of conventional sexually transmitted diseases (STDs), including provision of correct therapy, health education, condom promotion and partner notification, could result in a reduced incidence of HIV infection. Our objectives were to assess patients' needs for health education and to assess the quality of STD management in terms of health education, condom promotion, partner notification, the validity of the clinical diagnoses and the adequacy of the treatments prescribed. The study subjects were sampled systematically, according to their gender. Patients included in the study were given a standardized interview and their clinical records reviewed. Specimens were collected for laboratory investigations. For each STD detected, the treatment was defined as adequate if drugs currently known to be active against that infection were prescribed. One hundred and seventy men and 161 women were included in the study (median age: females 22 years, males 26 years). While almost all patients believed their STD may have been caused by unprotected sexual intercourse, many also believed it may have been caused by other factors, such as bewitchment with traditional medicine. Only 21% of male and 37% of female patients received any education about STD transmission during the clinic visit, and only 25% of male and 36% of female patients received education about condom use. As a result of the low sensitivity of the clinicians' diagnoses, 16% of men and 61% of women left the clinic with at least one infection inadequately treated. The majority of patients were not receiving education for the prevention of STDs including HIV. Many were not receiving adequate treatment for their infections. The introduction of a syndromic management protocol in this setting would substantially reduce the proportion of inadequately-treated patients. However, syndromic protocols, and the means by which they are implemented, need to take into account problems with the clinical detection of genital ulcerative disease and candidiasis in women.

Eight competitive male swimmers completed a standardized 365.8 m (400 yd) freestyle swimming trial at a fixed pace (approximately 90% of maximal effort) while wearing a torso swim suit (TOR) or a standard racing suit (STD). Oxygen uptake (VO2), blood lactate, heart rate (HR), and distance per stroke (DPS) measurements were obtained. In addition, a video-computer system was used to collect velocity data during a prone underwater glide following a maximal leg push-off from the side of the pool while wearing the TOR and STD suits. These data were used to calculate the total distance covered during the glides. VO2 (3.76 +/- 0.16 vs 3.92 +/- 0.18 l.min-1) and lactate (8.08 +/- 0.53 vs, 9.66 +/- 0.66 mM) were significantly (P < 0.05) lower during the TOR trial than the STD trial. HR was not different (P > 0.05) between the TOR (170.1 +/- 5.1 b.min-1) and STD (173.5 +/- 5.7 b.min-1) trials. DPS was significantly greater during the TOR (2.70 +/- 0.066 m.stroke-1) versus STD (2.58 +/- 0.054 m.stroke-1) trial. A significantly greater total distance was covered during the prone glide while wearing the TOR (2.05 +/- 0.067 m) compared to the STD (2.00 +/- 0.080 m) suit. These findings demonstrate that a specially designed torso suit reduces the energy demand of swimming compared to a standard racing suit which may be due to a reduction in body drag.

The other STDs. Linked with HIV transmission, they are attracting new attention.

PubMed

Lande, R E

1992-12-01

Health officials began neglecting sexually transmitted diseases (STDs) (syphilis, gonorrhea, chlamydia, trichomoniasis, and chancroid) when the AIDS epidemic began. They now refocus efforts on STDs because data indicate that STDs facilitate HIV transmission. Even though the risk of HIV transmission is lower in people with nonulcerative STDs than those with genital ulcers (0-4 vs. 2-5 times), the link between nonulcerative STDs and HIV transmission is a greater problem since nonulcerative STD cases occur more often than genital ulcers. Many AIDS control programs execute STD control activities. Countries must improve existing STD control programs. They should strengthen STD surveillance. Viet Nam has established surveillance sites at STD clinics in 4 cities. Training different health providers in STD control would make STD services accessible to more people. These providers include nurses, midwives, pharmacists, and even traditional healers and should be based at pharmacies and primary health care, maternal and child health, and family planning clinics. Primary health care workers should use symptoms to diagnose and treat STDs rather than laboratory tests. 1 drawback of this syndromic approach is that about 50% of women do not exhibit STD symptoms. STD control programs must guarantee a steady reserve of drugs. In Zimbabwe, primary health clinics receive STD drugs from a decentralized drug distribution system (5-8 warehouses) rather than the older centralized system (1 warehouse). This has reduced the waiting time from 6 months to 4-6 weeks. Programs need to encourage individuals to seek early treatment of STDs via health education campaigns (e.g., mass media), outreach to high risk groups such as prostitutes and the patron, and contact tracing. STD counselors should promote condom use. An STD program in Nairobi, Kenya informs patients to use a condom during sex with any causal sex partner, shows patients how to put on and take off the condom, and tells them where they can obtain condoms.

Standard deviation of carotid young's modulus and presence or absence of plaque improves prediction of coronary heart disease risk.

The stiffness of large arteries and the presence or absence of plaque are associated with coronary heart disease (CHD). Because arterial walls are biologically heterogeneous, the standard deviation of Young's modulus (YM-std) of the large arteries may better predict coronary atherosclerosis. However, the role of YM-std in the occurrence of coronary events has not been addressed so far. Therefore, this study investigated whether the carotid YM-std and the presence or absence of plaque improved CHD risk prediction. One hundred and three patients with CHD (age 66 ± 11 years) and 107 patients at high risk of atherosclerosis (age 61 ± 7 years) were recruited. Carotid YM was measured by the vessel texture matching method, and YM-std was calculated. Carotid intima-media thickness was measured by the MyLab 90 ultrasound Platform employed dedicated software RF-tracking technology. In logistic regression analysis, YM-std (OR = 1·010; 95% CI = 1·003-1·016), carotid plaque (OR = 16·759; 95% CI = 3·719-75·533) and YM-std plus plaque (OR = 0·989; 95% CI = 0·981-0·997) were independent predictors of CHD. The traditional risk factors (TRF) plus YM-std plus plaque model showed a significant improvement in area under the receiver-operating characteristic curve (AUC), which increased from 0·717 (TRF only) to 0·777 (95% CI for the difference in adjusted AUC: 0·010-0·110). Carotid YM-std is a powerful independent predictor of CHD. Adding plaque and YM-std to TRF improves CHD risk prediction. © 2016 Scandinavian Society of Clinical Physiology and Nuclear Medicine.

Bartram, Peter N.

1989-01-01

The current Life Sciences Laboratory Equipment (LSLE) microcomputer for life sciences experiment data acquisition is now obsolete. Among the weaknesses of the current microcomputer are small memory size, relatively slow analog data sampling rates, and the lack of a bulk data storage device. While life science investigators normally prefer data to be transmitted to Earth as it is taken, this is not always possible. No down-link exists for experiments performed in the Shuttle middeck region. One important aspect of a replacement microcomputer is provision for in-flight storage of experimental data. The Write Once, Read Many (WORM) optical disk was studied because of its high storage density, data integrity, and the availability of a space-qualified unit. In keeping with the goals for a replacement microcomputer based upon commercially available components and standard interfaces, the system studied includes a Small Computer System Interface (SCSI) for interfacing the WORM drive. The system itself is designed around the STD bus, using readily available boards. Configurations examined were: (1) master processor board and slave processor board with the SCSI interface; (2) master processor with SCSI interface; (3) master processor with SCSI and Direct Memory Access (DMA); (4) master processor controlling a separate STD bus SCSI board; and (5) master processor controlling a separate STD bus SCSI board with DMA.

OBJECTIVES: To determine the effectiveness of an intervention for pharmacy workers in improving their recognition and management of sexually transmitted disease (STD) syndromes. METHODS: We randomly selected 14 districts (total population nearly 4 million) from the 24 districts of low socioeconomic status in Lima, Peru. We randomly assigned paired districts to receive training and support for management and prevention of STDs or a control intervention about management of diarrhoea. The STD intervention included interactive luncheon seminars on recognition and management of four STD syndromes (urethral discharge, vaginal discharge, genital ulcers, and pelvic inflammatory disease) and STD/HIV prevention counselling; monthly pharmacy visits by "prevention salespersons" who distributed materials that included "STD/HIV prevention packets" containing information, condoms, and cards given to patients for referral of their sex partners; and workshops for physicians on managing patients with STD syndromes referred from pharmacies. Standardized simulated patients visited pharmacies in intervention and control districts at one, three, and six months after training to assess outcomes. FINDINGS: Standardized simulated patients reported significantly better recognition and management (appropriate antimicrobial regimens provided for discharge syndromes and referral to specially trained physicians for genital ulcers or pelvic inflammatory disease) by pharmacy workers of all four STD syndromes. They also reported significantly more frequent recommendations for use of condoms and treatment of partners at pharmacies in intervention districts than in control districts (by "intention-to-train" analyses, P<0.05 for 47/48 primary outcome comparisons). CONCLUSION: Training was feasible and effectively improved pharmacy workers' practices. PMID:14758407

Previous space flight computers have been costly in terms of both hardware and software. The Ruggedized STD Bus Microcomputer is based on the commercial Mostek/Pro-Log STD Bus. Ruggedized PC cards can be based on commercial cards from more than 60 manufacturers, reducing hardware cost and design time. Software costs are minimized by using standard 8-bit microprocessors and by debugging code using commercial versions of the ruggedized flight boards while the flight hardware is being fabricated.

Sexually transmitted diseases (STD) are an important contraindication for intrauterine device (IUD) insertion. Nevertheless, laboratory testing for STD is not possible in many settings. The objective of this study is to evaluate the use of risk assessment algorithms to predict STD and subsequent IUD-related complications among IUD candidates. Among 615 IUD users in Kenya, the following algorithms were evaluated: 1) an STD algorithm based on US Agency for International Development (USAID) Technical Working Group guidelines: 2) a Centers for Disease Control and Prevention (CDC) algorithm for management of chlamydia; and 3) a data-derived algorithm modeled from study data. Algorithms were evaluated for prediction of chlamydial and gonococcal infection at 1 month and complications (pelvic inflammatory disease [PID], IUD removals, and IUD expulsions) over 4 months. Women with STD were more likely to develop complications than women without STD (19% vs 6%; risk ratio = 2.9; 95% CI 1.3-6.5). For STD prediction, the USAID algorithm was 75% sensitive and 48% specific, with a positive likelihood ratio (LR+) of 1.4. The CDC algorithm was 44% sensitive and 72% specific, LR+ = 1.6. The data-derived algorithm was 91% sensitive and 56% specific, with LR+ = 2.0 and LR- = 0.2. Category-specific LR for this algorithm identified women with very low (< 1%) and very high (29%) infection probabilities. The data-derived algorithm was also the best predictor of IUD-related complications. These results suggest that use of STD algorithms may improve selection of IUD users. Women at high risk for STD could be counseled to avoid IUD, whereas women at moderate risk should be monitored closely and counseled to use condoms.

Currently, individuals at risk for sexually transmitted diseases (STDs) are tested extragenitally only if indicated, most often when there is a history of self-reported symptoms or self-reported anal sex. The sensitivity of such selective symptom- and sexual history-based testing for detection of anorectal STD has not been determined. All men having sex with men (MSM) and swingers (heterosexual couples who have sex with other heterosexual couples and their self-identified heterosexual sex partners) attending our STD clinic (consults: n = 1690) from January 2010 until February 2011 were universally tested for urogenital, anorectal, and oropharyngeal Chlamydia trachomatis and Neisseria gonorrhoeae infections (STD). We compared STD prevalence at anorectal site based on universal versus selective testing. Sensitivity of selective symptom- and sexual history-based testing for anorectal STD was 52% for homosexual MSM, 40% for bisexual MSM, 43% for bisexual male swingers, 40% for heterosexual male swingers, and 47% for female swingers. Universal testing of STD clinic clients who were MSM and swingers yielded more than half of all anorectal STD infections and is more sensitive for identifying anorectal STD infections compared with selective testing. Universal testing may be a more effective strategy for interrupting the ongoing transmission in high-risk sexual networks.

The purpose of this study was to determine whether a brief (6–8 sessions) cognitive-behavioral treatment for temporomandibular dysfunction-related pain could be efficacious in reducing pain, pain-related interference with lifestyle and depressive symptoms. The patients were 101 men and women with pain in the area of the temporomandibular joint of at least 3 months duration, randomly assigned to either Standard Treatment (STD; n=49) or to Standard Treatment + Cognitive-Behavioral skills training (STD+CBT; n=52). Patients were assessed at posttreatment (6 weeks), 12 weeks, 24 weeks, 36 weeks, and 52 weeks. Linear mixed model analyses of reported pain indicated that both treatments yielded significant decreases in pain, with the STD+CBT condition resulting in steeper decreases in pain over time compared to the STD condition. Somatization, self-efficacy and readiness for treatment emerged as significant moderators of outcome, such that those low in somatization, or higher in self-efficacy or readiness, and treated with STD+CBT reported lower pain over time. Somatization was also a significant moderator of treatment effects on pain-related interference with functioning, with those low on somatization reporting less pain interference over time when treated in the STD+CBT condition. It was concluded that brief treatments can yield significant reductions in pain, life interference and depressive symptoms in TMD sufferers, and that the addition of cognitive-behavioral coping skills will add to efficacy, especially for those low in somatization, or high in readiness or self-efficacy.

2013-01-01

At sexually transmitted disease (STD) clinics, advances in testing technology coupled with increasing demands and diminishing resources have promoted the use of testing-only visits (clinic visits with testing for STDs but no full examination) to meet increasing demands for STD services. The aims of the present study were to estimate the prevalence of STD diagnoses that could become "missed diagnoses" if patients would use testing-only visits and to examine patient characteristics associated with these potential missed diagnoses. We conducted a self-administered survey of STD-related symptoms and sexual risk behaviors in patients seeking routine clinical care at 3 STD clinics. Medical charts were abstracted to estimate the prevalence of viral STDs, trichomoniasis, and other diagnoses from standard clinical services that could become missed diagnoses. Of 2582 patients included, the median age was 24 years and 50% were women. In women, overall, 3.2% were diagnosed as having a viral STD; 9.6%, trichomoniasis; and 41.0%, vulvovaginal candidiasis or symptomatic bacterial vaginosis. The prevalence of these potential missed diagnoses varied by patient characteristics, but in women who reported no symptoms, the prevalence of trichomoniasis was still 6.3%. In men, 19.3% received a diagnosis of urethritis but tested negative for both gonorrhea and chlamydia; this prevalence varied from 15.7% in those who reported no symptoms to 32.6% in those who reported malodor. A high proportion of STD clients received diagnoses from standard care visits that would be missed by testing-only visits. When patients, even those asymptomatic, use testing-only visits, missed diagnoses of STDs or related genital tract conditions can be substantial. The potential disadvantages of testing-only visits should be weighed against the advantages of such visits.

Exposure to workplace hazards, such as dust, solvents, and fumes, has the potential to adversely affect the health of people. However, the effects of workplace hazards on health may differ when exposure occurs at different times in the circadian cycle, and among people who work longer hours or who do not obtain adequate sleep. The aim of the present study was to document exposures to workplace hazards across a national sample of New Zealanders, comparing people who work a standard 08:00 -17:00 h Monday-to-Friday working week (Std hours) and those who do not (N-Std hours). New Zealanders (n = 10 000) aged 20-64 yrs were randomly selected from the Electoral Roll to take part in a nationwide survey of workplace exposures. Telephone interviews were conducted between 2004 and 2006, using a six-part questionnaire addressing demographics, detailed information on the current or most recent job (including exposures to a range of workplace hazards), sleep, sleepiness, and health status. N-Std hours were categorised on the basis of: being required to start work prior to 07:00 h or finish work after 21:00 h and/or; having a regular on-call commitment (at least once per week) and/or; working rotating shifts and/or; working night shift(s) in the last month. The response rate was 37% (n = 3003), with 22.2% of participants (n = 656) categorised as working N-Std hours. Industry sectors with the highest numbers of participants working N-Std hours were manufacturing, health and community services, and agriculture, fishing, and forestry. Response rate was 37% (n = 3003) with 22.2% (n = 656) categorised as working N-Std hours. Participants working N-Std hours were more likely to be exposed to all identified hazards, including multiple hazards (OR = 2.45, 95% CI = 2.01-3.0) compared to those working Std hours. Participants working N-Std hours were also more likely to report 'never/rarely' getting enough sleep (OR = 1.38, 95% CI = 1.15-1.65), 'never/rarely' waking refreshed (OR = 1.23, 95% CI = 1.04-1.47), and excessive sleepiness (OR = 1.77, 95% CI = 1.29-2.42). New Zealanders working N-Std hours are more likely to be exposed to hazards in the workplace, to be exposed to multiple hazards, and to report inadequate sleep and excessive sleepiness than their colleagues working a standard 08:00-17:00 h Monday-to-Friday working week. More research is needed on the effects of exposure to hazardous substances outside the usual waking day, on the effects of exposure to multiple hazards, and on the combination of hazard exposure and sleep restriction as a result of shift work.

CT reconstruction techniques for improved accuracy of lung CT airway measurement

DOE Office of Scientific and Technical Information (OSTI.GOV)

Rodriguez, A.; Ranallo, F. N.; Judy, P. F.

Purpose: To determine the impact of constrained reconstruction techniques on quantitative CT (qCT) of the lung parenchyma and airways for low x-ray radiation dose. Methods: Measurement of small airways with qCT remains a challenge, especially for low x-ray dose protocols. Images of the COPDGene quality assurance phantom (CTP698, The Phantom Laboratory, Salem, NY) were obtained using a GE discovery CT750 HD scanner for helical scans at x-ray radiation dose-equivalents ranging from 1 to 4.12 mSv (12–100 mA s current–time product). Other parameters were 40 mm collimation, 0.984 pitch, 0.5 s rotation, and 0.625 mm thickness. The phantom was sandwiched betweenmore » 7.5 cm thick water attenuating phantoms for a total length of 20 cm to better simulate the scatter conditions of patient scans. Image data sets were reconstructed using STANDARD (STD), DETAIL, BONE, and EDGE algorithms for filtered back projection (FBP), 100% adaptive statistical iterative reconstruction (ASIR), and Veo reconstructions. Reduced (half) display field of view (DFOV) was used to increase sampling across airway phantom structures. Inner diameter (ID), wall area percent (WA%), and wall thickness (WT) measurements of eight airway mimicking tubes in the phantom, including a 2.5 mm ID (42.6 WA%, 0.4 mm WT), 3 mm ID (49.0 WA%, 0.6 mm WT), and 6 mm ID (49.0 WA%, 1.2 mm WT) were performed with Airway Inspector (Surgical Planning Laboratory, Brigham and Women’s Hospital, Boston, MA) using the phase congruency edge detection method. The average of individual measures at five central slices of the phantom was taken to reduce measurement error. Results: WA% measures were greatly overestimated while IDs were underestimated for the smaller airways, especially for reconstructions at full DFOV (36 cm) using the STD kernel, due to poor sampling and spatial resolution (0.7 mm pixel size). Despite low radiation dose, the ID of the 6 mm ID airway was consistently measured accurately for all methods other than STD FBP. Veo reconstructions showed slight improvement over STD FBP reconstructions (4%–9% increase in accuracy). The most improved ID and WA% measures were for the smaller airways, especially for low dose scans reconstructed at half DFOV (18 cm) with the EDGE algorithm in combination with 100% ASIR to mitigate noise. Using the BONE + ASIR at half BONE technique, measures improved by a factor of 2 over STD FBP even at a quarter of the x-ray dose. Conclusions: The flexibility of ASIR in combination with higher frequency algorithms, such as BONE, provided the greatest accuracy for conventional and low x-ray dose relative to FBP. Veo provided more modest improvement in qCT measures, likely due to its compatibility only with the smoother STD kernel.« less

In this work we describe the Horizontal Ice Nucleation Chamber (HINC) as a new instrument to measure ambient ice-nucleating particle (INP) concentrations for conditions relevant to mixed-phase clouds. Laboratory verification and validation experiments confirm the accuracy of the thermodynamic conditions of temperature (T) and relative humidity (RH) in HINC with uncertainties in T of ±0.4 K and in RH with respect to water (RHw) of ±1.5 %, which translates into an uncertainty in RH with respect to ice (RHi) of ±3.0 % at T > 235 K. For further validation of HINC as a field instrument, two measurement campaigns were conducted in winters 2015 and 2016 at the High Altitude Research Station Jungfraujoch (JFJ; Switzerland, 3580 m a. s. l. ) to sample ambient INPs. During winters 2015 and 2016 the site encountered free-tropospheric conditions 92 and 79 % of the time, respectively. We measured INP concentrations at 242 K at water-subsaturated conditions (RHw = 94 %), relevant for the formation of ice clouds, and in the water-supersaturated regime (RHw = 104 %) to represent ice formation occurring under mixed-phase cloud conditions. In winters 2015 and 2016 the median INP concentrations at RHw = 94 % was below the minimum detectable concentration. At RHw = 104 %, INP concentrations were an order of magnitude higher, with median concentrations in winter 2015 of 2.8 per standard liter (std L-1; normalized to standard T of 273 K and pressure, p, of 1013 hPa) and 4.7 std L-1 in winter 2016. The measurements are in agreement with previous winter measurements obtained with the Portable Ice Nucleation Chamber (PINC) of 2.2 std L-1 at the same location. During winter 2015, two events caused the INP concentrations at RHw = 104 % to significantly increase above the campaign average. First, an increase to 72.1 std L-1 was measured during an event influenced by marine air, arriving at the JFJ from the North Sea and the Norwegian Sea. The contribution from anthropogenic or other sources can thereby not be ruled out. Second, INP concentrations up to 146.2 std L-1 were observed during a Saharan dust event. To our knowledge this is the first time that a clear enrichment in ambient INP concentration in remote regions of the atmosphere is observed during a time of marine air mass influence, suggesting the importance of marine particles on ice nucleation in the free troposphere.

Multidimensional family therapy HIV/STD risk-reduction intervention: an integrative family-based model for drug-involved juvenile offenders.

Drug and juvenile justice involved youths show remarkably high rates of human immunodeficiency virus (HIV)/sexually transmitted disease (STD) risk behaviors. However, existing interventions aimed at reducing adolescent HIV risk behavior have rarely targeted these vulnerable young adolescents, and many approaches focus on individual-level change without attention to family or contextual influences. We describe a new, family-based HIV/ STD prevention model that embeds HIV/STD focused multifamily groups within an adolescent drug abuse and delinquency evidence-based treatment, Multidimensional Family Therapy (MDFT). The approach has been evaluated in a multisite randomized clinical trial with juvenile justice involved youths in the National Institute on Drug Abuse Criminal Justice Drug Abuse Treatment Studies (www.cjdats.org). Preliminary baseline to 6-month outcomes are promising. We describe research on family risk and protective factors for adolescent problem behaviors, and offer a rationale for family-based approaches to reduce HIV/STD risk in this population. We describe the development and implementation of the Multidimensional Family Therapy HIV/STD risk-reduction intervention (MDFT-HIV/ STD) in terms of using multifamily groups and their integration in standard MDFT and also offers a clinical vignette. The potential significance of this empirically based intervention development work is high; MDFT-HIV/STD is the first model to address largely unmet HIV/STD prevention and sexual health needs of substance abusing juvenile offenders within the context of a family-oriented evidence-based intervention.

Katz, Richard; Barto, Rod

2009-01-01

A compact and flexible controller has been developed to provide MIL-STD- 1553B Remote Terminal (RT) communications and supporting and related functions with minimal demand on the resources of the system in which the controller is to be installed. (MIL-STD-1553B is a military standard that encompasses a method of communication and electrical-interface requirements for digital electronic subsystems connected to a data bus. MIL-STD-1553B is commonly used in defense and space applications.) Many other MIL-STD-1553B RT controllers are complicated, and to enable them to function, it is necessary to provide software and to use such ancillary separate hardware devices as microprocessors and dual-port memories. The present controller functions without need for software and any ancillary hardware. In addition, it contains a flexible system interface and extensive support hardware while including on-chip error-checking and diagnostic support circuitry. This controller is implemented within part of a modern field-programmable gate array.

Cheville, Andrea L., E-mail: Cheville.andrea@mayo.edu; Brinkmann, Debra H.; Ward, Shelly B.

2013-03-15

Background: This prospective cohort study was designed to determine whether the amount of radiation delivered to the nonpathological lymph nodes (LNs) that drain the arm can be significantly reduced by integrating single-photon emission computed tomography (SPECT)/computed tomography (CT) scans into radiation treatment planning. Methods: SPECT-CT scans were acquired for the 28 patients with stage I or II breast cancer and fused with the routinely obtained radiation oncology planning CT scans.

This prospective cohort study was designed to determine whether the amount of radiation delivered to the nonpathological lymph nodes (LNs) that drain the arm can be significantly reduced by integrating single-photon emission computed tomography (SPECT)/computed tomography (CT) scans into radiation treatment planning. SPECT-CT scans were acquired for the 28 patients with stage I or II breast cancer and fused with the routinely obtained radiation oncology planning CT scans. Arm-draining LNs were contoured with 0.5-cm margins automatically using a threshold of 50% maximum intensity.

NASA Handbook for Models and Simulations: An Implementation Guide for NASA-STD-7009

NASA Technical Reports Server (NTRS)

Steele, Martin J.

2013-01-01

The purpose of this Handbook is to provide technical information, clarification, examples, processes, and techniques to help institute good modeling and simulation practices in the National Aeronautics and Space Administration (NASA). As a companion guide to NASA-STD- 7009, Standard for Models and Simulations, this Handbook provides a broader scope of information than may be included in a Standard and promotes good practices in the production, use, and consumption of NASA modeling and simulation products. NASA-STD-7009 specifies what a modeling and simulation activity shall or should do (in the requirements) but does not prescribe how the requirements are to be met, which varies with the specific engineering discipline, or who is responsible for complying with the requirements, which depends on the size and type of project. A guidance document, which is not constrained by the requirements of a Standard, is better suited to address these additional aspects and provide necessary clarification. This Handbook stems from the Space Shuttle Columbia Accident Investigation (2003), which called for Agency-wide improvements in the "development, documentation, and operation of models and simulations"' that subsequently elicited additional guidance from the NASA Office of the Chief Engineer to include "a standard method to assess the credibility of the models and simulations."2 General methods applicable across the broad spectrum of model and simulation (M&S) disciplines were sought to help guide the modeling and simulation processes within NASA and to provide for consistent reporting ofM&S activities and analysis results. From this, the standardized process for the M&S activity was developed. The major contents of this Handbook are the implementation details of the general M&S requirements ofNASA-STD-7009, including explanations, examples, and suggestions for improving the credibility assessment of an M&S-based analysis.

To compare the incidence of sexually transmitted diseases (STD) in British troops in the tropics with that in a standard population. Retrospective analysis of STD clinic records over one calendar year. A British Military Hospital in the Tropics serving 1441 resident personnel. All patients attending a STD clinic. 815 cases of STD were recorded during the study period, giving incidence rate of 56,558 per 100,000 population per year. When compared with a matched population from England and Wales, the age standardised relative risk for STD amongst tropical troops was 25.0 (95% confidence interval 24.9 to 25.1). Thirty nine percent of cases reported prostitute contact as a source of their disease. Of patients questioned about condom usage, 70% reported that they did not normally use a condom. British troops spending short periods of time in a tropical environment are significantly more likely to acquire a STD than men in the same age groups in England and Wales. The proportions of cases who reported that they did not use condoms and the number who cited prostitute contact as a source of infection indicate that even greater sexual education of troops on deployment overseas may be required.

How to Develop and Interpret a Credibility Assessment of Numerical Models for Human Research: NASA-STD-7009 Demystified

NASA Technical Reports Server (NTRS)

Nelson, Emily S.; Mulugeta, Lealem; Walton, Marlei; Myers, Jerry G.

2014-01-01

In the wake of the Columbia accident, the NASA-STD-7009 [1] credibility assessment was developed as a unifying platform to describe model credibility and the uncertainties in its modeling predictions. This standard is now being adapted by NASAs Human Research Program to cover a wide range of numerical models for human research. When used properly, the standard can improve the process of code development by encouraging the use of best practices. It can also give management more insight in making informed decisions through a better understanding of the models capabilities and limitations.To a newcomer, the abstractions presented in NASA-STD-7009 and the sheer volume of information that must be absorbed can be overwhelming. This talk is aimed at describing the credibility assessment, which is the heart of the standard, in plain terms. It will outline how to develop a credibility assessment under the standard. It will also show how to quickly interpret the graphs and tables that result from the assessment and how to drill down from the top-level view to the foundation of the assessment. Finally, it will highlight some of the resources that are available for further study.

Background Diarrhea associated with parvovirus infection is common in dogs. Supportive care is the mainstay of treatment, but recovery may be prolonged and mortality rate can be high. Modification of the intestinal bacterial microbiota has been promising in human and veterinary medicine as an adjunctive treatment of various enteric diseases. Objectives To investigate the safety and efficacy of fecal microbiota transplantation (FMT) on the clinical recovery of puppies with acute hemorrhagic diarrhea syndrome. Animals Sixty‐six puppies with parvovirus infection were evaluated at 2 veterinary hospitals. Methods Randomized clinical trial. Puppies were randomly distributed into 2 groups: standard treatment (STD) and standard treatment + FMT (STD + FMT). The STD puppies (n = 33) received only treatment with IV fluids and antimicrobials and the STD + FMT puppies (n = 33) received FMT in addition to standard treatment. For FMT, 10 g of feces from a healthy dog diluted in 10 mL of saline were administered rectally 6‐12 hours post‐admission. Results Among survivors, treatment with FMT was associated with faster resolution of diarrhea (P < .001) and shorter hospitalization time (P = .001; median, 3 days in STD + FMT; median, 6 days in STD) compared to standard treatment. Mortality in STD was 36.4% (12/33) as compared to 21.2% (7/33) in puppies treated with FMT, but there was no statistical difference between groups (P = .174). Polymerase chain reaction indicated that all animals carried canine parvovirus, strain CPV‐2b. Conclusions Fecal microbiota transplantation in parvovirus‐infected puppies was associated with faster resolution of diarrhea. PMID:29460302

Can experiential-didactic training improve clinical STD practices?

2011-06-01

High rates of sexually transmitted diseases (STDs) present an ongoing costly public health challenge. One approach to reduce STD transmission is to increase the number of clinicians adopting the Centers for Disease Control and Prevention's STD Treatment Guidelines. This evaluation assesses the effectiveness of a 3-day experiential and didactic training to translate recommendations into practice by increasing clinician knowledge and skills and helping participants anticipate and overcome barriers to implementation. Between 2001 and 2004, 110 direct care clinicians from 10 states participated in one of 27 standardized 3-day interactive trainings offered by the Denver STD/human immunodeficiency virus (HIV) Prevention Training Center. STD/HIV knowledge and clinical skills were measured before, immediately after, and 6 months after training. Practice patterns were assessed before training and after 6 months. Structural barriers to implementation were identified 6 months post-training. Trainees demonstrated significant post-training gains in mean knowledge scores immediately post-training (P < 0.001) and 6 months post-training (P = 0.002). After 6 months, self-reported mean skill levels remained significantly improved compared to precourse (P < 0.05) for each of 27 skills including STD risk assessment, clinical examination, diagnosis, and treatment. Self-reported improvement in practice patterns was significant for 23 of 35 practices (P < 0.05) 6 months post-training. Participants indicated that inadequate time (52.9%), facilities/equipment (51.5%), and staffing (47.1%) interfered with implementation of recommended practices. Experiential-didactic STD/HIV training can modestly improve knowledge, clinical skills, and implementation of STD recommended practices 6 months after training. Further research is needed to identify the impact of improved clinical practices on STD/HIV transmission.

Chancroid detected by polymerase chain reaction--Jackson, Mississippi, 1994-1995.

PubMed

1995-08-04

Chancroid is a sexually transmitted disease (STD) caused by infection with Haemophilus ducreyi and is characterized by genital ulceration. Chancroid is underreported in the United States (1), reflecting, in part, difficulties in diagnosis because of clinical similarities between chancroid and other ulcerative STDs. In addition, laboratory confirmation by culture is 53%-84% sensitive and often is unavailable in clinical settings (2). In September 1994, clinicians at the District V STD clinic of the Mississippi State Department of Health (MSDH) in Jackson reported examining patients with genital ulcers characteristic of chancroid but lacked capacity to confirm the diagnosis. To determine the cause of the ulcers, MSDH, in conjunction with CDC, conducted an investigation of all patients with genital ulcers examined at the Jackson STD clinic during October 20, 1994-February 1, 1995. This report summarizes the findings of the investigation.

We confirmed safety and immunogenicity of mass-produced vaccine baits carrying an experimental, commercial-source plague vaccine (RCN-F1/V307) expressing Yersinia pestis V and F1 antigens. Forty-five juvenile black-tailed prairie dogs ( Cynomys ludovicianus ) were randomly divided into three treatment groups (n=15 animals/group). Animals in the first group received one standard-dose vaccine bait (5×10 7 plaque-forming units [pfu]; STD). The second group received a lower-dose bait (1×10 7 pfu; LOW). In the third group, five animals received two standard-dose baits and 10 were left untreated but in contact. Two vaccine-treated and one untreated prairie dogs died during the study, but laboratory analyses ruled out vaccine involvement. Overall, 17 of 33 (52%; 95% confidence interval for binomial proportion [bCI] 34-69%) prairie dogs receiving vaccine-laden bait showed a positive anti-V antibody response on at least one sampling occasion after bait consumption, and eight (24%; bCI 11-42%) showed sustained antibody responses. The STD and LOW groups did not differ (P≥0.78) in their proportions of overall or sustained antibody responses after vaccine bait consumption. Serum from one of the nine (11%; bCI 0.3-48%) surviving untreated, in-contact prairie dogs also had detectable antibody on one sampling occasion. We did not observe any adverse effects related to oral vaccination.

HB-Line Plutonium Oxide Data Collection Strategy

DOE Office of Scientific and Technical Information (OSTI.GOV)

Watkins, R.; Varble, J.; Jordan, J.

2015-05-26

HB-Line and H-Canyon will handle and process plutonium material to produce plutonium oxide for feed to the Mixed Oxide Fuel Fabrication Facility (MFFF). However, the plutonium oxide product will not be transferred to the MFFF directly from HB-Line until it is packaged into a qualified DOE-STD-3013-2012 container. In the interim, HB-Line will load plutonium oxide into an inner, filtered can. The inner can will be placed in a filtered bag, which will be loaded into a filtered outer can. The outer can will be loaded into a certified 9975 with getter assembly in compliance with onsite transportation requirement, for subsequentmore » storage and transfer to the K-Area Complex (KAC). After DOE-STD-3013-2012 container packaging capabilities are established, the product will be returned to HB-Line to be packaged into a qualified DOE-STD-3013-2012 container. To support the transfer of plutonium oxide to KAC and then eventually to MFFF, various material and packaging data will have to be collected and retained. In addition, data from initial HB-Line processing operations will be needed to support future DOE-STD-3013-2012 qualification as amended by the HB-Line DOE Standard equivalency. As production increases, the volume of data to collect will increase. The HB-Line data collected will be in the form of paper copies and electronic media. Paper copy data will, at a minimum, consist of facility procedures, nonconformance reports (NCRs), and DCS print outs. Electronic data will be in the form of Adobe portable document formats (PDFs). Collecting all the required data for each plutonium oxide can will be no small effort for HB-Line, and will become more challenging once the maximum annual oxide production throughput is achieved due to the sheer volume of data to be collected. The majority of the data collected will be in the form of facility procedures, DCS print outs, and laboratory results. To facilitate complete collection of this data, a traveler form will be developed which identifies the required facility procedures, DCS print outs, and laboratory results needed to assemble a final data package for each HB-Line plutonium oxide interim oxide can. The data traveler may identify the specific values (data) required to be extracted from the collected facility procedures and DCS print outs. The data traveler may also identify associated criteria to be checked. Inevitably there will be procedure anomalies during the course of the HB-Line plutonium oxide campaign that will have to be addressed in a timely manner.« less

NASA-STD-7009 Guidance Document for Human Health and Performance Models and Simulations

2014-01-01

Rigorous verification, validation, and credibility (VVC) processes are imperative to ensure that models and simulations (MS) are sufficiently reliable to address issues within their intended scope. The NASA standard for MS, NASA-STD-7009 (7009) [1] was a resultant outcome of the Columbia Accident Investigation Board (CAIB) to ensure MS are developed, applied, and interpreted appropriately for making decisions that may impact crew or mission safety. Because the 7009 focus is engineering systems, a NASA-STD-7009 Guidance Document is being developed to augment the 7009 and provide information, tools, and techniques applicable to the probabilistic and deterministic biological MS more prevalent in human health and performance (HHP) and space biomedical research and operations.

Application of IUS equipment and experience to orbit transfer vehicles of the 90's

NASA Astrophysics Data System (ADS)

Bangsund, E.; Keeney, J.; Cowgill, E.

1985-10-01

This paper relates experiences with the IUS program and the application of that experience to Future Orbit Transfer Vehicles. More specifically it includes the implementation of the U.S. Air Force Space Division high reliability parts standard (SMASO STD 73-2C) and the component/system test standard (MIL-STD-1540A). Test results from the parts and component level testing and the resulting system level test program for fourteen IUS flight vehicles are discussed. The IUS program has had the highest compliance with these standards and thus offers a benchmark of experience for future programs demanding extreme reliability. In summary, application of the stringent parts standard has resulted in fewer failures during testing and the stringent test standard has eliminated design problems in the hardware. Both have been expensive in costs and schedules, and should be applied with flexibility.

Optimal experimental design for assessment of enzyme kinetics in a drug discovery screening environment.

2011-05-01

A penalized expectation of determinant (ED)-optimal design with a discrete parameter distribution was used to find an optimal experimental design for assessment of enzyme kinetics in a screening environment. A data set for enzyme kinetic data (V(max) and K(m)) was collected from previously reported studies, and every V(max)/K(m) pair (n = 76) was taken to represent a unique drug compound. The design was restricted to 15 samples, an incubation time of up to 40 min, and starting concentrations (C(0)) for the incubation between 0.01 and 100 μM. The optimization was performed by finding the sample times and C(0) returning the lowest uncertainty (S.E.) of the model parameter estimates. Individual optimal designs, one general optimal design and one, for laboratory practice suitable, pragmatic optimal design (OD) were obtained. In addition, a standard design (STD-D), representing a commonly applied approach for metabolic stability investigations, was constructed. Simulations were performed for OD and STD-D by using the Michaelis-Menten (MM) equation, and enzyme kinetic parameters were estimated with both MM and a monoexponential decay. OD generated a better result (relative standard error) for 99% of the compounds and an equal or better result [(root mean square error (RMSE)] for 78% of the compounds in estimation of metabolic intrinsic clearance. Furthermore, high-quality estimates (RMSE < 30%) of both V(max) and K(m) could be obtained for a considerable number (26%) of the investigated compounds by using the suggested OD. The results presented in this study demonstrate that the output could generally be improved compared with that obtained from the standard approaches used today.

Ligand-receptor binding affinities from saturation transfer difference (STD) NMR spectroscopy: the binding isotherm of STD initial growth rates.

PubMed

Angulo, Jesús; Enríquez-Navas, Pedro M; Nieto, Pedro M

2010-07-12

The direct evaluation of dissociation constants (K(D)) from the variation of saturation transfer difference (STD) NMR spectroscopy values with the receptor-ligand ratio is not feasible due to the complex dependence of STD intensities on the spectral properties of the observed signals. Indirect evaluation, by competition experiments, allows the determination of K(D), as long as a ligand of known affinity is available for the protein under study. Herein, we present a novel protocol based on STD NMR spectroscopy for the direct measurements of receptor-ligand dissociation constants (K(D)) from single-ligand titration experiments. The influence of several experimental factors on STD values has been studied in detail, confirming the marked impact on standard determinations of protein-ligand affinities by STD NMR spectroscopy. These factors, namely, STD saturation time, ligand residence time in the complex, and the intensity of the signal, affect the accumulation of saturation in the free ligand by processes closely related to fast protein-ligand rebinding and longitudinal relaxation of the ligand signals. The proposed method avoids the dependence of the magnitudes of ligand STD signals at a given saturation time on spurious factors by constructing the binding isotherms using the initial growth rates of the STD amplification factors, in a similar way to the use of NOE growing rates to estimate cross relaxation rates for distance evaluations. Herein, it is demonstrated that the effects of these factors are cancelled out by analyzing the protein-ligand association curve using STD values at the limit of zero saturation time, when virtually no ligand rebinding or relaxation takes place. The approach is validated for two well-studied protein-ligand systems: the binding of the saccharides GlcNAc and GlcNAcbeta1,4GlcNAc (chitobiose) to the wheat germ agglutinin (WGA) lectin, and the interaction of the amino acid L-tryptophan to bovine serum albumin (BSA). In all cases, the experimental K(D) measured under different experimental conditions converged to the thermodynamic values. The proposed protocol allows accurate determinations of protein-ligand dissociation constants, extending the applicability of the STD NMR spectroscopy for affinity measurements, which is of particular relevance for those proteins for which a ligand of known affinity is not available.

To examine the physiological and performance responses to a heat-acclimatization camp in highly trained professional team-sport athletes. Eighteen male Australian Rules Football players trained for 2 wk in hot ambient conditions (31-33°C, humidity 34-50%). Players performed a laboratory-based heat-response test (24-min walk + 24 min seated; 44°C), a YoYo Intermittent Recovery Level 2 Test (YoYoIR2; indoor, temperate environment, 23°C) and standardized training drills (STD; outdoor, hot environment, 32°C) at the beginning and end of the camp. The heat-response test showed partial heat acclimatization (eg, a decrease in skin temperature, heart rate, and sweat sodium concentration, P < .05). In addition, plasma volume (PV, CO rebreathing, +2.68 [0.83; 4.53] mL/kg) and distance covered during both the YoYoIR2 (+311 [260; 361] m) and the STD (+45.6 [13.9; 77.4] m) increased postcamp (P < .01). None of the performance changes showed clear correlations with PV changes (r < .24), but the improvements in running STD distance in hot environment were correlated with changes in hematocrit during the heat-response test (r = -.52, 90%CI [-.77; -.12]). There was no clear correlation between the performance improvements in temperate and hot ambient conditions (r < .26). Running performance in both hot and temperate environments was improved after a football training camp in hot ambient conditions that stimulated heat acclimatization. However, physiological and performance responses were highly individual, and the absence of correlations between physical-performance improvements in hot and temperate environments suggests that their physiological basis might differ.

Timely notification and treatment of sex partners exposed to a sexually transmitted disease (STD) is essential to reduce reinfection and transmission. Our objectives were to determine factors associated with patient-initiated notification of sex partners and preferences regarding standard partner referral versus expedited partner therapy (EPT). Participants diagnosed with gonorrhea, chlamydia, trichomoniasis, or nongonococcal urethritis within the previous year were administered a baseline survey asking about demographics, sexual history, and partner treatment preferences (standard partner referral vs. EPT). They identified up to 4 sex partners within the past 2 months, and answered questions on relationship characteristics, quality, and notification self-efficacy. At follow-up, participants with a current STD were asked whether they notified their partners. Generalized estimating equations were used to evaluate the associations between predictor variables and partner notification. Of the 201 subjects enrolled, 157 had a current STD diagnosis, and 289 sex partners were identified. The rate of successful partner notification was 77.3% (157/203 sex partners). Partner notification was increased if the subject had a long-term relationship with a sex partner (odds ratio: 3.07; 95% confidence interval: 1.43, 6.58), considered the partner to be a main partner (odds ratio: 2.53; 95% confidence interval: 1.43, 6.58), or had increased notification self-efficacy. Overall, participants did not prefer EPT over standard referral; however, females, those with higher education levels, and those with a prior STD preferred EPT. Patient-initiated partner referral is more successful in patients with increased self-efficacy who have stronger interpersonal relationships with their sex partners.

Purpose To investigate whether telephone-based continuing care (TEL) is a promising alternative to traditional face-to-face counseling for clients in treatment for substance abuse. Methods Patients with alcohol and/or cocaine dependence who had completed a 4-week intensive outpatient program were randomly assigned through urn randomization into one of three 12-week interventions: standard continuing care (STD), in-person relapse prevention (RP), or telephone-based continuing care (TEL). This study performed cost, cost-effectiveness, and cost-benefit analyses of TEL and RP compared to STD, using results from the randomized clinical trial with two years of follow up (359 participants). In addition, the study examined the potential moderating effect of baseline patient costs on economic outcomes. Results The study found that TEL was less expensive per client from the societal perspective ($569) than STD ($870) or RP ($1,684). TEL also was also significantly more effective, with an abstinence rate of 57.1% compared to 46.7% for STD (p<0.05). Thus TEL dominated STD, with a highly favorable negative incremental cost-effectiveness ratio (−$1,400 per abstinent year). TEL also proved favorable under a benefit-cost perspective. Conclusions TEL proved to be a cost-effective and cost-beneficial contributor to long-term recovery over two years. Because TEL dominated STD care interventions, wider adoption should be considered.

AIDSCAP seeks a private sector solution to the STD self-treatment dilemma.

PubMed

Henry, K

1995-03-01

Many people in developing countries faced with long waits at health clinics, expensive prescriptions and laboratory tests, stigma associated with sexually transmitted disease (STD) clinic attendance, and the disdain of some health providers opt to buy over-the-counter drugs against their STDs at pharmacies and in markets, and treat themselves. Such self-treatment may lead to partially treated infections and serious complications, not to mention the associated increased risk of contracting or transmitting HIV from having sexual intercourse while still infected with a STD. Population Services International in collaboration with Family Health International's AIDSTECH Project developed a standard prepackaged therapy for male urethritis to be tested in a pilot program in Cameroon. The package was named MSTOP, with MST being the French acronym for STD, and consisted of a pouch containing antibiotics to treat gonorrhea and chlamydia, the two most common causes of urethritis in Cameroon, an educational brochure, detailed instructions on how to take the medication, two cards for referring sexual partners for diagnosis and treatment, and eight Prudence condoms. Medication included two tablets of cefuroxime axetil to be taken in a single oral dose and 20 tablets of doxycycline to be taken orally twice daily for ten days. The kit retailed for US$17, at the low end of what people were willing to pay for urethritis treatment on the market, with Glaxo and Ciba-Geigy supplying the drugs at a preferential price. By the completion of all necessary preliminary studies and consultations, however, new Ministry of Health (MOH) officials had come to power who opposed the original plan of selling MSTOP without prescriptions in pharmacies and health care centers. MSTOP was therefore approved for sale March 1993 only by prescription in 21 health care facilities which served mainly university students and the military and in three private pharmacies near the university campus. More than 86% of the patients who bought the kit reported being satisfied with it, 82% reported treatment compliance, more than 50% notified sex partners, and 84% of those who had sex during treatment used some or all of the condoms in the kit. Subsequent to the ten-month pilot ending March 1994, the MOH failed to support expanding MSTOP sales to more pharmacies to increase its accessibility. Plans for a second phase of the pilot project in Cameroon were abandoned. Change in MOH leadership, resistance from physicians and pharmacy associations, the country's drug registration laws, which precluded use of the cheapest and most effective drug, and lack of acceptance of the syndromic approach to STD management thwarted the potential success of this pilot and its future widespread programmatic expansion. Health officials in six other countries have expressed their interest in working with AIDSCAP to test prepackaged STD therapy.

Four-Channel PC/104 MIL-STD-1553 Circuit Board

2004-01-01

The mini bus interface card (miniBIC) is the first four-channel electronic circuit board that conforms to MIL-STD-1553 and to the electrical-footprint portion of PC/104. [MIL-STD-1553 is a military standard that encompasses a method of communication and electrical- interface requirements for digital electronic subsystems connected to a data bus. PC/104 is an industry standard for compact, stackable modules that are fully compatible (in architecture, hardware, and software) with personal-computer data- and power-bus circuitry.] Prior to the development of the miniBIC, only one- and two-channel PC/104 MIL-STD-1553 boards were available. To obtain four channels, it was necessary to include at least two boards in a PC/104 stack. In comparison with such a two-board stack, the miniBIC takes up less space, consumes less power, and is more reliable. In addition, the miniBIC includes 32 digital input/output channels. The miniBIC (see figure) contains four MIL-STD-1553B hybrid integrated circuits (ICs), four transformers, a field-programmable gate array (FPGA), and an Industry Standard Architecture (ISA) interface. Each hybrid IC includes a MILSTD-1553 dual transceiver, memory-management circuitry, processor interface logic circuitry, and 64Kx16 bits of shared static random access memory. The memory is used to configure message and data blocks. In addition, 23 16-bit registers are available for (1) configuring the hybrid IC for, and starting it in, various modes of operation; (2) reading the status of the functionality of the hybrid IC; and (3) resetting the hybrid IC to a known state. The miniBIC can operate as a remote terminal, bus controller, or bus monitor. The FPGA provides the chip-select and data-strobe signals needed for operation of the hybrid ICs. The FPGA also receives interruption signals and forwards them to the ISA bus. The ISA interface connects the address, data, and control interfaces of the hybrid ICs to the ISA backplane. Each channel is, in effect, a MIL-STD-1553 interface that can operate either independently of the others or else as a redundant version of one of the others. The transformer in each channel provides electrical isolation between the rest of the miniBIC circuitry and the bus to which that channel is connected.

This report provides site-specific return level analyses for rain, snow, and straight-line wind extreme events. These analyses are in support of the 10-year review plan for the assessment of meteorological natural phenomena hazards at Los Alamos National Laboratory (LANL). These analyses follow guidance from Department of Energy, DOE Standard, Natural Phenomena Hazards Analysis and Design Criteria for DOE Facilities (DOE-STD-1020-2012), Nuclear Regulatory Commission Standard Review Plan (NUREG-0800, 2007) and ANSI/ ANS-2.3-2011, Estimating Tornado, Hurricane, and Extreme Straight-Line Wind Characteristics at Nuclear Facility Sites. LANL precipitation and snow level data have been collected since 1910, although not all years are complete.more » In this report the results from the more recent data (1990–2014) are compared to those of past analyses and a 2004 National Oceanographic and Atmospheric Administration report. Given the many differences in the data sets used in these different analyses, the lack of statistically significant differences in return level estimates increases confidence in the data and in the modeling and analysis approach.« less

Evaluation of human engineering design standard (MSFC-STD-267A) in the design of manned space vehicles

NASA Technical Reports Server (NTRS)

Rogers, J. G.

1972-01-01

The major conclusion of the detailed examination of the human factors engineering design standard is that it is unsuitable for future spacecraft design. The standard, published in 1966, was not intended to be a zero or reduced gravity standard and was directed primarily toward ground support equipment and technology. Futhermore, ambiguities, conflicts, and unenforceable requirements contribute to the difficulty. The role of man in future space missions and its impact on human engineering standards are also discussed, and it is concluded that greater standardization is vital to the success of future missions. A survey of NASA/MSFC contractors was made, and it was found that MSFC-STD-267A is largely ignored and the most significant problems are inaccessibility and nonspecificity of the data. The resistance of contract management and designer and of program managers is a primary reason for poor human engineering design. Specific recommendations for improvement of format and organization, including an interim solution, are given.

Track and mode controller (TMC): a software executive for a high-altitude pointing and tracking experiment

NASA Astrophysics Data System (ADS)

Michnovicz, Michael R.

1997-06-01

A real-time executive has been implemented to control a high altitude pointing and tracking experiment. The track and mode controller (TMC) implements a table driven design, in which the track mode logic for a tracking mission is defined within a state transition diagram (STD). THe STD is implemented as a state transition table in the TMC software. Status Events trigger the state transitions in the STD. Each state, as it is entered, causes a number of processes to be activated within the system. As these processes propagate through the system, the status of key processes are monitored by the TMC, allowing further transitions within the STD. This architecture is implemented in real-time, using the vxWorks operating system. VxWorks message queues allow communication of status events from the Event Monitor task to the STD task. Process commands are propagated to the rest of the system processors by means of the SCRAMNet shared memory network. The system mode logic contained in the STD will autonomously sequence in acquisition, tracking and pointing system through an entire engagement sequence, starting with target detection and ending with aimpoint maintenance. Simulation results and lab test results will be presented to verify the mode controller. In addition to implementing the system mode logic with the STD, the TMC can process prerecorded time sequences of commands required during startup operations. It can also process single commands from the system operator. In this paper, the author presents (1) an overview, in which he describes the TMC architecture, the relationship of an end-to-end simulation to the flight software and the laboratory testing environment, (2) implementation details, including information on the vxWorks message queues and the SCRAMNet shared memory network, (3) simulation results and lab test results which verify the mode controller, and (4) plans for the future, specifically as to how this executive will expedite transition to a fully functional system.

Miniaturized thermocycler based on thermoelectric heating for diagnosis of sexually transmitted disease by DNA amplification

2017-05-01

Sexually transmitted disease (STD) is among the most common infectious diseases; therefore, it is necessary to develop sensitive early diagnostic techniques. As the gold standard, polymerase chain reaction (PCR) has been most widely employed for STD diagnosis; however, PCR requires large and expensive instruments. In this study, miniaturized thermal cycler using Peltier modules was developed for the PCR analysis. In comparison with the conventional PCR instrument, the Peltier-based micro-PCR (P-mPCR) device developed in this study enables one to amplify and successfully distinguish between DNA of different sizes. Furthermore, by using the clinical vaginal sample collected with the vaginal swab and tampon, different kinds of STD bacteria could be detected with high accuracy (˜94.19%) and high sensitivity (˜95.6%). Therefore, the P-mPCR device will be applicable in STD diagnosis as well as the detection of other bacteria/viruses using DNA amplification in regions including those with limited resources.

Street-involved youth (SIY) carry a disproportionate burden of sexually transmitted diseases (STD). Studies among adults suggest that improving housing stability may be an effective primary prevention strategy for improving sexual health. Housing options available to SIY offer varying degrees of stability and adult supervision. This study investigated whether housing options offering more stability and adult supervision are associated with fewer STD and related risk behaviors among SIY. A cross-sectional study was performed using public health survey and laboratory data collected from Toronto SIY in 2010. Three exposure categories were defined a priori based on housing situation: (1) stable and supervised housing, (2) stable and unsupervised housing, and (3) unstable and unsupervised housing. Multivariate logistic regression was used to test the association between housing category and current or recent STD. Secondary analyses were performed using the following secondary outcomes: blood-borne infection, recent binge-drinking, and recent high-risk sexual behavior. The final analysis included 184 SIY. Of these, 28.8 % had a current or recent STD. Housing situation was stable and supervised for 12.5 %, stable and unsupervised for 46.2 %, and unstable and unsupervised for 41.3 %. Compared to stable and supervised housing, there was no significant association between current or recent STD among stable and unsupervised housing or unstable and unsupervised housing. There was no significant association between housing category and risk of blood-borne infection, binge-drinking, or high-risk sexual behavior. Although we did not demonstrate a significant association between stable and supervised housing and lower STD risk, our incorporation of both housing stability and adult supervision into a priori defined exposure groups may inform future studies of housing-related prevention strategies among SIY. Multi-modal interventions beyond housing alone may also be required to prevent sexual morbidity among these vulnerable youth.

NASA-STD-6001B Test 1 Upward Flame Propagation; Sample Length Impact on MOC Investigation

NASA Technical Reports Server (NTRS)

Harper, Susana Tapia; Juarez, Alfredo; Woods, Brenton L.; Beeson, Harold D.

2017-01-01

Understanding the combustion behavior of materials in the elevated oxygen environments of habitable spacecraft is of utmost importance to crew safety and mission success. Currently, certification for unrestricted flight usage of a material with respect to flammability involves passing the Upward Flame Propagation Test of NASA-STD-6001B (Test 1). This test evaluates materials in a standardized test configuration for two failure criteria: self-extinguishment within 15 cm (6 in.) and the propensity of flame propagation by means of flaming material transfer. By the NASA standard, full-length samples are 30 cm (12 in.) in length; however, factors independent of the test method such as limited material availability or various nonstandard test configurations limit the full pretest sample lengths available for test. This paper characterizes the dependence, if any, of pretest sample length on NASA-STD-6001B Test 1 results. Testing was performed using the Maximum Oxygen Concentration (MOC) Threshold Method to obtain a data set for each sample length tested. In addition, various material types, including cloth (Nomex), foam (TA-301) and solids (Ultem), were tested to investigate potential effects of test specimen types. Though additional data needs to be generated to provide statistical confidence, preliminary findings are that use of variable sample lengths has minimal impact on NASA-STD-6001B flammability performance and MOC determination.

To describe important details of the design and operational features of the Mwanza sexually transmitted diseases (STD) control programme. To assess the feasibility of the intervention, the distribution of STD syndromes observed, the clinical effectiveness of syndromic STD case management, the utilisation of STD services by the population, and the quality of syndromic STD services delivered at rural health units. The intervention was integrated into rural primary healthcare (PHC) units. It comprised improved STD case management using the syndromic approach, facilitated by a regional programme office which ensured the training of health workers, a reliable supply of effective drugs, and regular support supervision. Five studies were performed to evaluate operational performance: (i) a survey of register books to collect data on patients presenting with STDs and reproductive tract infections (RTIs) to rural health units with improved STD services, (ii) a survey of register books from health units in communities without improved services, (iii) a survey of register books from referral clinics, (iv) a home based cross sectional study of STD patients who did not return to the intervention health units for follow up, (v) a cross sectional survey of reported STD treatment seeking behaviour in a random cohort of 8845 adults served by rural health units. During the 2 years of the Mwanza trial, 12,895 STD syndromes were treated at the 25 intervention health units. The most common syndromes were urethral discharge (67%) and genital ulcers (26%) in men and vaginal discharge (50%), lower abdominal tenderness (33%), and genital ulcers (13%) in women. Clinical treatment effectiveness was high in patients from whom complete follow up data were available, reaching between 81% and 98% after first line treatment and 97%-99% after first, second, and third line treatment. Only 26% of patients referred to higher levels of health care had presented to their referral institutions. During the trial period, data from the cohort showed that 12.8% of men and 8.6% of women in the intervention communities experienced at least one STD syndrome. Based on various approaches, utilisation of the improved health units by symptomatic STD patients in these communities was estimated at between 50% and 75%. During the first 6 months of intervention attendance at intervention units increased by 53%. Thereafter, the average attendance rate was about 25% higher than in comparison communities. Home visits to 367 non-returners revealed that 89% had been free of symptoms after treatment, but 28% became symptomatic again within 3 months of treatment. 100% of these patients reported that they had received treatment, but only 74% had been examined, only 57% had been given health education, and only 30% were offered condoms. Patients did not fully recall which treatment they had been given, but possibly only 63% had been treated exactly according to guidelines. This study demonstrated that it is feasible to integrate effective STD services into the existing PHC structure of a developing country. Improved services attract more patients, but additional educational efforts are needed to further improve treatment seeking behaviour. Furthermore, clear treatment guidelines, a reliable drug supply system, and regular supervision are critical. All efforts should be made to treat patients on the spot, without delay, as referral to higher levels of care led to a high number of dropouts. The syndromic approach to STD control should be supported by at least one reference clinic and laboratory per country to ensure monitoring of prevalent aetiologies, of the development of bacterial resistance, and of the effectiveness of the syndromic algorithms in use.

Purpose Shame and stigma associated with sexually transmitted diseases (STDs) are barriers to adolescents seeking prompt and appropriate diagnosis and treatment. However, little is known about how these constructs are related to STD-protective behaviors, such as condom-protected intercourse. Thus, we prospectively examined the relationship between shame and stigma and condom-use in adolescent females. Methods 192 African American females age 17.4 ± 1.7 years (range 15-21) were recruited for the study from local teen oriented health clinics. At baseline, participants completed demographic and psychosocial measures (including STD-related shame and stigma), and chart or laboratory confirmed history of STDs was obtained. At six months follow-up, rate of condom-protected intercourse in past 14 days prior to follow-up was assessed. Participants’ baseline shame and stigma scores, prior history of STDs, and select demographic and theoretically important psychosocial variables were entered into a hierarchical linear regression model to predict condom-protected intercourse in the 14 days prior to the 6 month follow-up assessment. Results After controlling for variables identified in bivariate correlations, STD-related shame was significantly predictive of condom-protected intercourse in the 14 days prior to follow-up, with higher shame predicting higher rates of condom-protected intercourse. Conclusions Future prevention efforts attempting to reduce adolescents’ risks for STDs and HIV may benefit from addressing STD-related shame and stigma in addition to explicitly linking health-promoting behavior changes (condom use) to a decreased likelihood of future infection with STDs.

The Savannah River National Laboratory (SRNL) has developed prototype equipment to demonstrate remote surveying of Inner and Outer DOE Standard 3013 containers for fixed and transferable contamination in accordance with DOE Standard 3013 and 10 CFR 835 Appendix B. When fully developed the equipment will be part of a larger suite of equipment used to package material in accordance with DOE Standard 3013 at the Pit Disassembly and Conversion Project slated for installation at the Savannah River Site. The prototype system consists of a small six-axis industrial robot with an end effector consisting of a force sensor, vacuum gripper andmore » a three fingered pneumatic gripper. The work cell also contains two alpha survey instruments, swipes, swipe dispenser, and other ancillary equipment. An external controller interfaces with the robot controller, survey instruments and other ancillary equipment to control the overall process. SRNL is developing automated equipment for the Pit Disassembly and Conversion (PDC) Project that is slated for the Savannah River Site (SRS). The equipment being developed is automated packaging equipment for packaging plutonium bearing materials in accordance with DOE-STD-3013-2004. The subject of this paper is the development of a prototype Radiological Survey Station (RSS). Other automated equipment being developed for the PDC includes the Bagless transfer System, Outer Can Welder, Gantry Robot System (GRS) and Leak Test Station. The purpose of the RSS is to perform a frisk and swipe of the DOE Standard 3013 Container (either inner can or outer can) to check for fixed and transferable contamination. This is required to verify that the contamination levels are within the limits specified in DOE-STD-3013-2004 and 10 CFR 835, Appendix D. The surface contamination limit for the 3013 Outer Can (OC) is 500 dpm/100 cm2 (total) and 20 dpm/100 cm2 (transferable). This paper will concentrate on the RSS developments for the 3013 OC but the system for the 3013 Inner Can (IC) is nearly identical.« less

Determinants of Pain Treatment Response and Non-Response: Identification of TMD Patient Subgroups

PubMed Central

Litt, Mark D.; Porto, Felipe B.

2013-01-01

The purpose of the present study was to determine if we could identify a specific subtype of temporomandibular disorder (TMD) pain patients that does not respond to treatment. Patients were 101 men and women with chronic TMD pain recruited from the community and randomly assigned to one of two treatment conditions: a standard conservative care (STD) condition or a standard care plus cognitive-behavioral treatment condition (STD+CBT) in which patients received all elements of STD, but also received cognitive-behavioral coping skills training. Growth mixture modeling, incorporating a series of treatment-related predictors, was used to distinguish several distinct classes of responders or non-responders to treatment based on reported pain over a one-year follow-up period. Results indicated that treatment non-responders accounted for 16% of the sample, and did not differ from treatment responders on demographics or temporomandibular joint pathology, but that they reported more psychiatric symptoms, poorer coping, and higher levels of catastrophizing. Treatment-related predictors of membership in treatment responder groups versus the non-responder group included the addition of CBT to standard treatment, treatment attendance, and decreasing catastrophization. It was concluded that CBT may be made more efficacious for TMD patients by placing further emphasis on decreasing catastrophization and on individualizing care. PMID:24094979

Summary Background and objectives When hemodialysis dose is scaled to body water (V), women typically receive a greater dose than men, but their survival is not better given a similar dose. This study sought to determine whether rescaling dose to body surface area (SA) might reveal different associations among dose, sex, and mortality. Design, setting, participants, & measurements Single-pool Kt/V (spKt/V), equilibrated Kt/V, and standard Kt/V (stdKt/V) were computed using urea kinetic modeling on a prevalent cohort of 7229 patients undergoing thrice-weekly hemodialysis. Data were obtained from the Centers for Medicare & Medicaid Services 2008 ESRD Clinical Performance Measures Project. SA-normalized stdKt/V (SAN-stdKt/V) was calculated as stdKt/V × ratio of anthropometric volume to SA/17.5. Patients were grouped into sex-specific dose quintiles (reference: quintile 1 for men). Adjusted hazard ratios (HRs) for 1-year mortality were calculated using Cox regression. Results spKt/V was higher in women (1.7±0.3) than in men (1.5±0.2; P<0.001), but SAN-stdKt/V was lower (women: 2.3±0.2; men: 2.5±0.3; P<0.001). For both sexes, mortality decreased as spKt/V increased, until spKt/V was 1.6–1.7 (quintile 4 for men: HR, 0.62; quintile 3 for women: HR, 0.64); no benefit was observed with higher spKt/V. HR for mortality decreased further at higher SAN-stdKt/V in both sexes (quintile 5 for men: HR, 0.69; quintile 5 for women: HR, 0.60). Conclusions SA-based dialysis dose results in dose-mortality relationships substantially different from those with volume-based dosing. SAN-stdKt/V analyses suggest women may be relatively underdosed when treated by V-based dosing. SAN-stdKt/V as a measure for dialysis dose may warrant further study. PMID:22977208

The two largest studies of mammalian target of rapamycin inhibitor treatment of autosomal dominant polycystic kidney disease (ADPKD) demonstrated no clear benefit on the primary endpoint of total kidney volume (TKV) or on eGFR. The present study evaluated two levels of rapamycin on the 12-month change in (125)I-iothalamate GFR (iGFR) as the primary endpoint and TKV secondarily. In a 12-month open-label pilot study, 30 adult patients with ADPKD were randomly assigned to low-dose (LD) rapamycin (rapamycin trough blood level, 2-5 ng/ml) (LD group, n=10), standard-dose (STD) rapamycin trough level (>5-8 ng/ml) (STD group, n=10), or standard care (SC group, n=10). They were evaluated with iGFR and noncontrast computed tomography. Change in iGFR at 12 months was significantly higher in the LD group (7.7±12.5 ml/min per 1.73 m(2); n=9) than in the SC group (-11.2 ± 9.1 ml/min per 1.73 m(2); n=9) (LD versus SC: P<0.01). Change in iGFR at 12 months in the STD group (1.6 ± 12.1 ml/min per 1.73 m(2); n=8) was not significantly greater than that in the SC group (P=0.07), but it was in the combined treatment groups (LD+STD versus SC: P<0.01). Neither eGFR calculated by the CKD-Epidemiology Collaboration equation nor TKV (secondary endpoint) changed significantly from baseline to 12 months in any of the groups. On the basis of results of the mixed model, during the study, patients in the LD group had significantly lower trough blood levels of rapamycin (mean range ± SD, 2.40 ± 0.64 to 2.90 ± 1.20 ng/ml) compared with those in the STD group (3.93 ± 2.27 to 5.77 ± 1.06 ng/ml) (P<0.01). Patients with ADPKD receiving LD rapamycin demonstrated a significant increase in iGFR compared with those receiving standard care, without a significant effect on TKV after 12 months.

Technical Note: Image filtering to make computer-aided detection robust to image reconstruction kernel choice in lung cancer CT screening

DOE Office of Scientific and Technical Information (OSTI.GOV)

Ohkubo, Masaki, E-mail: mook@clg.niigata-u.ac.jp

Purpose: In lung cancer computed tomography (CT) screening, the performance of a computer-aided detection (CAD) system depends on the selection of the image reconstruction kernel. To reduce this dependence on reconstruction kernels, the authors propose a novel application of an image filtering method previously proposed by their group. Methods: The proposed filtering process uses the ratio of modulation transfer functions (MTFs) of two reconstruction kernels as a filtering function in the spatial-frequency domain. This method is referred to as MTF{sub ratio} filtering. Test image data were obtained from CT screening scans of 67 subjects who each had one nodule. Imagesmore » were reconstructed using two kernels: f{sub STD} (for standard lung imaging) and f{sub SHARP} (for sharp edge-enhancement lung imaging). The MTF{sub ratio} filtering was implemented using the MTFs measured for those kernels and was applied to the reconstructed f{sub SHARP} images to obtain images that were similar to the f{sub STD} images. A mean filter and a median filter were applied (separately) for comparison. All reconstructed and filtered images were processed using their prototype CAD system. Results: The MTF{sub ratio} filtered images showed excellent agreement with the f{sub STD} images. The standard deviation for the difference between these images was very small, ∼6.0 Hounsfield units (HU). However, the mean and median filtered images showed larger differences of ∼48.1 and ∼57.9 HU from the f{sub STD} images, respectively. The free-response receiver operating characteristic (FROC) curve for the f{sub SHARP} images indicated poorer performance compared with the FROC curve for the f{sub STD} images. The FROC curve for the MTF{sub ratio} filtered images was equivalent to the curve for the f{sub STD} images. However, this similarity was not achieved by using the mean filter or median filter. Conclusions: The accuracy of MTF{sub ratio} image filtering was verified and the method was demonstrated to be effective for reducing the kernel dependence of CAD performance.« less

Comparing Study Populations of Men Who Have Sex with Men: Evaluating Consistency Within Repeat Studies and Across Studies in the Seattle Area Using Different Recruitment Methodologies

2013-01-01

There is no gold standard for recruiting unbiased samples of men who have sex with men (MSM). To assess differing recruitment methods, we compared Seattle-area MSM samples from: venue-day-time sampling-based National HIV Behavioral Surveillance (NHBS) surveys in 2008 and 2011, random-digit-dialed (RDD) surveys in 2003 and 2006, and STD clinic patient data 2001–2011. We compared sociodemographics, sexual and drug-associated behavior, and HIV status and testing. There was generally good consistency between the two NHBS surveys and within STD clinic data across time. NHBS participants reported higher levels of drug-associated and lower levels of sexual risk than STD clinic patients. RDD participants differed from the other study populations in sociodemographics and some risk behaviors. While neither NHBS nor the STD clinic study populations may be representative of all MSM, both appear to provide consistent samples of MSM subpopulations across time that can provide useful information to guide HIV prevention.

Network Extender for MIL-STD-1553 Bus

NASA Technical Reports Server (NTRS)

Marcus, Julius; Hanson, T. David

2003-01-01

An extender system for MIL-STD-1553 buses transparently couples bus components at multiple developer sites. The bus network extender is a relatively inexpensive system that minimizes the time and cost of integration of avionic systems by providing a convenient mechanism for early testing without the need to transport the usual test equipment and personnel to an integration facility. This bus network extender can thus alleviate overloading of the test facility while enabling the detection of interface problems that can occur during the integration of avionic systems. With this bus extender in place, developers can correct and adjust their own hardware and software before products leave a development site. Currently resident at Johnson Space Center, the bus network extender is used to test the functionality of equipment that, although remotely located, is connected through a MILSTD- 1553 bus. Inasmuch as the standard bus protocol for avionic equipment is that of MIL-STD-1553, companies that supply MIL-STD-1553-compliant equipment to government or industry and that need long-distance communication support might benefit from this network bus extender

Evaluation of different signal processing options in unilateral and bilateral cochlear freedom implant recipients using R-Space background noise.

PubMed

Brockmeyer, Alison M; Potts, Lisa G

2011-02-01

Difficulty understanding in background noise is a common complaint of cochlear implant (CI) recipients. Programming options are available to improve speech recognition in noise for CI users including automatic dynamic range optimization (ADRO), autosensitivity control (ASC), and a two-stage adaptive beamforming algorithm (BEAM). However, the processing option that results in the best speech recognition in noise is unknown. In addition, laboratory measures of these processing options often show greater degrees of improvement than reported by participants in everyday listening situations. To address this issue, Compton-Conley and colleagues developed a test system to replicate a restaurant environment. The R-SPACE™ consists of eight loudspeakers positioned in a 360 degree arc and utilizes a recording made at a restaurant of background noise. The present study measured speech recognition in the R-SPACE with four processing options: standard dual-port directional (STD), ADRO, ASC, and BEAM. A repeated-measures, within-subject design was used to evaluate the four different processing options at two noise levels. Twenty-seven unilateral and three bilateral adult Nucleus Freedom CI recipients. The participants' everyday program (with no additional processing) was used as the STD program. ADRO, ASC, and BEAM were added individually to the STD program to create a total of four programs. Participants repeated Hearing in Noise Test sentences presented at 0 degrees azimuth with R-SPACE restaurant noise at two noise levels, 60 and 70 dB SPL. The reception threshold for sentences (RTS) was obtained for each processing condition and noise level. In 60 dB SPL noise, BEAM processing resulted in the best RTS, with a significant improvement over STD and ADRO processing. In 70 dB SPL noise, ASC and BEAM processing had significantly better mean RTSs compared to STD and ADRO processing. Comparison of noise levels showed that STD and BEAM processing resulted in significantly poorer RTSs in 70 dB SPL noise compared to the performance with these processing conditions in 60 dB SPL noise. Bilateral participants demonstrated a bilateral improvement compared to the better monaural condition for both noise levels and all processing conditions, except ASC in 60 dB SPL noise. The results of this study suggest that the use of processing options that utilize noise reduction, like those available in ASC and BEAM, improve a CI recipient's ability to understand speech in noise in listening situations similar to those experienced in the real world. The choice of the best processing option is dependent on the noise level, with BEAM best at moderate noise levels and ASC best at loud noise levels for unilateral CI recipients. Therefore, multiple noise programs or a combination of processing options may be necessary to provide CI users with the best performance in a variety of listening situations.

The Space Station Power Distribution System has been baselined as a sinusoidal single phase, 440 VRMS system. This system has certain unique characteristics directly affecting its application. In particular, existing systematic description and control documents were modified to reflect the high operating frequency. This paper will discuss amendments made on Mil STD 704 (Electrical Power Characteristics), and Mil STD 461-B (Electromagnetic Emission and Susceptibility Requirements for the Control of Electromagnetic Interference). In some cases these amendments reflect changes of several orders of magnitude. Implications and impacts of these changes are discussed.

Our purpose was to determine the number of monitoring stations (medical institutions) necessary for estimating incidence rates in the surveillance system of infectious diseases in Japan. Infectious diseases were selected by the type of monitoring stations: 15 diseases in pediatrics stations, influenza in influenza stations, 3 diseases in ophthalmology stations and 5 diseases in the stations of sexually transmitted diseases (STD). For each type of monitoring station, 5 cases of the number of monitoring stations in each health center, including the number determined from presently established standards and the actual number in 1997, were given. It was assumed that monitoring stations were randomly selected among medical institutions in health centers. For each infectious disease, each case and each type of monitoring station, standard error rates of estimated numbers of incidence cases in the whole country were calculated in 1993-1997 using the data of the surveillance of infectious diseases. Among 5 cases of monitoring stations, the case satisfied the condition that those standard error rates were lower than the critical values, was selected. The critical values were 5% in pediatrics and influenza stations, and 10% in ophthalmology and STD stations. The numbers of monitoring stations in the selected cases were 3,000 in pediatrics stations, 5,000 in influenza stations (including all pediatrics stations), 605 in ophthalmology stations and 900 in STD stations.

Zimbabwe has an incidence of STD/HIV infection and measures are needed to explore the efficiency of clinics in providing adequate patient care. To explore the views or opinions of the currently employed staff of an STD/HIV clinic, and suggest a means for improvement thereof. A current position analysis was determined through observation of an STD/HIV clinic. An assessment was made using an adapted, designed questionnaire as interviews of 125 staff. Responses to questions were given as Yes or No responses. Data were analysed according to gender, using a two-sample t-test and chi-square tests. Yates' correction was made for continuity of smaller samples. A value of p < 0.05 was taken a significant. The mean average age of all staff was 31.7 years and 75% of the respondents were female. Notably, there were massive shortages of staff, poor communication with the Ministry of Health, little or no training of staff, poor infrastructure and quality, and a drop in safety standards. There is poor communication in the clinic, insufficient staff and inadequate training in place. Monitoring of STD incidence needs drastic improvement. Operational research needs to be conducted. There is little or no direct communication between committee members and decision makers with the staff and power-distance relationships are great.

Although lipid management in diabetes is standard practice, goals often are neither met nor maintained. Strategies for achieving lower targets have not been explored. The Stop Atherosclerosis in Native Diabetics Study randomized patients with diabetes to standard versus aggressive lipid and blood pressure goals for 36 months. To report strategies used to achieve and maintain lipid goals and to report adverse events (AEs). Adults with type 2 diabetes and no history of cardiovascular disease (N = 499) were randomized to standard (low-density lipoprotein cholesterol [LDL-C] ≤ 100 mg/dL, non-high-density lipoprotein cholesterol [non-HDL-C] ≤ 130 mg/dL) or aggressive (LDL-C ≤ 70 mg/dL, non-HDL-C ≤ 100 mg/dL) targets. An algorithm was started with statin monotherapy, with intestinally acting agents added as required to reach LDL-C targets.Triglyceride [TG]-lowering agents were next used to reach non-HDL-C goals. Lipid management was performed by mid-level practitioners, with physician consultation, by the use of point-of-care lipid determinations. On average, both groups achieved the LDL-C and non-HDL-C goals within 12 months and maintained them throughout the study. At 36 months, mean (SD) LDL-C and non-HDL-C were 72 (24) and 102 (29) mg/dL in the aggressive group (AGG) and 104 (20) and 138 (26) mg/dL, respectively, in the standard group (STD); systolic blood pressure targets were 115 and 130 mmHg, respectively. A total of 68% of participants reached target LDL-C for greater than 50% of the visits and 46% for greater than 75% of visits. At 36 months, the AGG averaged 1.5 lipid lowering medications and the STD 1.2. Statins were used in 91% and 68% of the AGG and STD; ezetimibe by 31% and 10%; fibrates by 8% and 18%. No serious AEs were observed; AEs occurred in 18% of the AGG and 14% of the STD. Standard and aggressive lipid targets can be safely maintained in diabetic patients. Standardized algorithms, point-of-care lipid testing, and nonphysician providers facilitate care delivery. © 2010 National Lipid Association. All rights reserved.

SU-F-T-87: Comparison of Advanced Radiotherapy Techniques for Post- Mastectomy Breast Cancer Patients

DOE Office of Scientific and Technical Information (OSTI.GOV)

Heins, D; Zhang, R; Hogstrom, K

2016-06-15

Purpose: To determine if bolus electron conformal therapy (Bolus-ECT) combined with intensity modulated x-ray therapy (IMXT) and flattening filter free volumetric modulated arc therapy (FFF-VMAT (6x and 10x)) can maintain equal or better dose coverage than standard volumetric modulated arc therapy (Std-VMAT) while reducing doses to organs at risk (OARs). Methods: Bolus-ECT with IMXT, FFF-VMAT, and Std-VMAT treatment plans were produced for ten post-mastectomy radiotherapy (PMRT) patients previously treated at our clinic. The treatment plans were created on commercially available treatment planning system (TPS) and all completed treatment plans were reviewed and approved by a radiation oncologist. The plans weremore » evaluated based on planning target volume (PTV) coverage, tumor control probability (TCP), dose homogeneity index (DHI), conformity index (CI), and dose to organs at risk (OAR). Results: All techniques produced clinically acceptable PMRT plans. Overall, Bolus-ECT with IMXT exhibited higher maximum dose compared to all VMAT techniques. Bolus-ECT with IMXT and FFF-VMAT10x had slightly improved TCP over FFF-VMAT6x and Std-VMAT. However, all VMAT techniques showed improved CI and DHI over Bolus-ECT with IMXT. All techniques showed very similar mean lung dose. Bolus-ECT with IMXT exhibited a reduced mean heart dose over Std-VMAT. Both FFF-VMAT techniques had higher mean heart dose compared to Std-VMAT. In addition, Bolus-ECT with IMXT was able to reduce mean dose to the contralateral breast compared to Std-VMAT and both FFF-VMAT techniques had comparable but slightly reduced dose compared to Std-VMAT. Conclusion: This work has shown that Bolus-ECT with IMXT produces clinically acceptable plans while reducing OAR doses. Both FFF-VMAT techniques are comparable to Std-VMAT with slight improvements. Even though all VMAT techniques produce more homogenous and conformal dose distributions, Bolus-ECT with IMXT is a viable option for treating post-mastectomy patients possibly leading to reduced risks of normal tissue complications.« less

The Sonagachi Project was initiated in Kolkata, India in 1992 as a STD/HIV intervention for sex workers. The project evolved to adopt strategies common to women’s empowerment programs globally (i.e., community mobilization, rights-based framing, advocacy, micro-finance) to address common factors that support effective, evidence-based HIV/STD prevention. The Sonagachi model is now a broadly diffused evidence-based empowerment program. We previously demonstrated significant condom use increases among female sex workers in a 16 month replication trial of the Sonagachi empowerment intervention (n = 110) compared to a control community (n = 106) receiving standard care of STD clinic, condom promotion, and peer education in two randomly assigned rural towns in West Bengal, India (Basu et al., 2004). This article examines the intervention’s impacts on 21 measured variables reflecting five common factors of effective HIV/STD prevention programs to estimate the impact of empowerment strategies on HIV/STD prevention program goals. The intervention which was conducted in 2000–2001 significantly: 1) improved knowledge of STDs and condom protection from STD and HIV, and maintained STD/HIV risk perceptions despite treatment; 2) provided a frame to motivate change based on reframing sex work as valid work, increasing disclosure of profession, and instilling a hopeful future orientation reflected in desire for more education or training; 3) improved skills in sexual and workplace negotiations reflected in increased refusal, condom decision-making, and ability to change work contract, but not ability to take leave; 4) built social support by increasing social interactions outside work, social function participation, and helping other sex workers; and 5) addressed environmental barriers of economic vulnerabilities by increasing savings and alternative income, but not working in other locations, nor reduced loan taking, and did not increase voting to build social capital. This study’s results demonstrate that, compared to narrowcast clinical and prevention services alone, empowerment strategies can significantly impact a broader range of factors to reduce vulnerability to HIV/STDs.

Dose painting to treat single-lobe prostate cancer with hypofractionated high-dose radiation using targeted external beam radiation: Is it feasible?

DOE Office of Scientific and Technical Information (OSTI.GOV)

Amini, Arya; Westerly, David C.; Waxweiler, Timothy V.

Targeted focal therapy strategies for treating single-lobe prostate cancer are under investigation. In this planning study, we investigate the feasibility of treating a portion of the prostate to full-dose external beam radiation with reduced dose to the opposite lobe, compared with full-dose radiation delivered to the entire gland using hypofractionated radiation. For 10 consecutive patients with low- to intermediate-risk prostate cancer, 2 hypofractionated, single-arc volumetric-modulated arc therapy (VMAT) plans were designed. The first plan (standard hypofractionation regimen [STD]) included the entire prostate gland, treated to 70 Gy delivered in 28 fractions. The second dose painting plan (DP) encompassed the involvedmore » lobe treated to 70 Gy delivered in 28 fractions, whereas the opposing, uninvolved lobe received 50.4 Gy in 28 fractions. Mean dose to the opposing neurovascular bundle (NVB) was considerably lower for DP vs STD, with a mean dose of 53.9 vs 72.3 Gy (p < 0.001). Mean penile bulb dose was 18.6 Gy for DP vs 19.2 Gy for STD (p = 0.880). Mean rectal dose was 21.0 Gy for DP vs 22.8 Gy for STD (p = 0.356). Rectum V{sub 70} (the volume receiving ≥70 Gy) was 2.01% for DP vs 2.74% for STD (p = 0.328). Bladder V{sub 70} was 1.69% for DP vs 2.78% for STD (p = 0.232). Planning target volume (PTV) maximum dose points were 76.5 and 76.3 Gy for DP and STD, respectively (p = 0.760). This study demonstrates the feasibility of using VMAT for partial-lobe prostate radiation in patients with prostate cancer involving 1 lobe. Partial-lobe prostate plans appeared to spare adjacent critical structures including the opposite NVB.« less

The intervention which was conducted in 2000-2001 significantly: 1) improved knowledge of STDs and condom protection from STD and HIV, and maintained STD/HIV risk perceptions despite treatment; 2) provided a frame to motivate change based on reframing sex work as valid work, increasing disclosure of profession, and instilling a hopeful future orientation reflected in desire for more education or training; 3) improved skills in sexual and workplace negotiations reflected in increased refusal, condom decision-making, and ability to change work contract, but not ability to take leave; 4) built social support by increasing social interactions outside work, social function participation, and helping other sex workers; and 5) addressed environmental barriers of economic vulnerabilities by increasing savings and alternative income, but not working in other locations, nor reduced loan taking, and did not increase voting to build social capital. This study's results demonstrate that, compared to narrowcast clinical and prevention services alone, empowerment strategies can significantly impact a broader range of factors to reduce vulnerability to HIV/STDs.

The aims of this study were to determine if feeding frequency (FF) of milk replacer (MR; meals/d) alters starter intake, growth, and efficiency of growth in nursery calves fed a conventional or accelerated MR. We hypothesized that smaller and more frequent MR meals would increase starter intake and growth when greater amounts of MR nutrients are fed to nursery calves. Forty-eight Holstein and Holstein-cross heifer and bull calves were assigned to treatments in a 2 × 2 factorial arrangement of MR and FF. Treatments included (1) standard 20% CP and 20% fat MR fed at 1.5% of body weight (BW; 2 meals/d; STD2), (2) standard 20% CP and 20% fat MR fed at 1.5% of BW (4 meals/d; STD4), (3) modified 26% CP and 18% fat MR fed at 2.0% of BW (2 meals/d; MOD2), and (4) modified 26% CP and 18% fat MR fed at 2.0% of BW (4 meals/d; MOD4; n=12). All calves were fed at 0600 and 1700 h and STD4 and MOD4 calves were fed 2 additional meals at 1100 and 1400 h, resulting in the same amount of MR offered for the 2 × and 4 × treatments. Treatments were fed from d 2 to 42 of age and all MR feeding rates were adjusted weekly to maintain MR solids intakes at 1.5 or 2.0% of BW for STD and MOD diets, respectively, and were reconstituted to 15% total solids. Milk replacer FF was reduced by 50% on d 36 and calves were weaned on d 42. Calves were housed in hutches bedded with straw and offered water and a texturized 18% CP starter ad libitum. Calf body weight and body structure were measured weekly and starter intake and fecal scores were measured daily. Through both 42 and 56 d, calves fed MOD had greater CP and fat intake, resulting in increased average daily gain, heart girth, circulating nonesterified fatty acids (NEFA), and muscle total lipid compared with calves fed STD diets. Calves fed MOD diets consumed less starter grain than STD calves but total dry matter intake was similar among treatments. Increased FF for STD calves resulted in greater starter intake at weaning but increasing FF of MOD calves did not have this effect. Due to differences in starter intake, total dry matter by calves through d 56 was similar across treatments. Additionally, increased FF tended to increase serum NEFA concentrations. Serum NEFA concentration was negatively correlated with starter intake. The BW of calves fed STD2 and STD4 treatments almost doubled and the BW of calves on the MOD2 and MOD4 treatments doubled by d 56. Increased FF of the conventional MR program but not accelerated MR program increased starter intake. Increased FF did not affect growth, starter intake, or gain:feed ratio.

Screening for gonorrhea (GC) and chlamydia (CT) and syphilis among HIV-positive (HIV+) men who have sex with men (MSM) is recommended at least annually. However, significant gaps in screening coverage exist. We conducted a quality improvement intervention to determine whether informing providers of preintervention screening rates and routinizing sexual risk assessment would improve sexually transmitted disease (STD) screening in a large HIV care clinic. In partnership with Kaiser Permanente Northern California, we developed and implemented a 10-item assessment addressing sexual and other behavioral risk factors among HIV+ MSM. We analyzed the proportion of patients screened for GC/CT and syphilis in a preintervention period (June 25-September 26, 2012) and during the intervention period (June 25-September 26, 2013). Of 364 HIV+ MSM seen for care during the intervention period, 47.3% completed the sexual risk assessment. Improvements in GC/CT screening and syphilis screening were observed; when comparing the preintervention period with the intervention period, the proportion of HIV+ MSM receiving GC/CT screening increased by 26.8% (31.6%-40.1%, P = 0.01) at any anatomical site and by 45% (19.5%-28.3%, P = 0.003) at the pharyngeal site. Syphilis screening significantly increased by 18.8% (48.7%-58.0%, P = 0.009). Overall STD screening increases were observed after this intervention that included didactic training on the urgency of STD screening needs for HIV+ MSM, a presentation of preintervention clinic STD screening data, and the implementation of self-reported sexual risk assessment. Additional efforts are needed to determine feasible ways to accurately assess the appropriateness of STD screening and success of interventions to improve STD screening.

This cross-sectional study describes the baseline prevalence and correlates of common bacterial and viral sexually transmitted diseases (STDs) and risk behaviors among individuals at high risk for HIV recruited in five low- and middle-income countries. Correlations of risk behaviors and demographic factors with prevalent STDs and the association of STDs with HIV prevalence are examined. Between 2,212 and 5,543 participants were recruited in each of five countries (China, India, Peru, Russia, and Zimbabwe). Standard protocols were used to collect behavioral risk information and biological samples for STD testing. Risk factors for HIV/STD prevalence were evaluated using logistic regression models. STD prevalence was significantly higher for women than men in all countries, and the most prevalent STD was Herpes simplex virus-type 2 (HSV-2). HIV prevalence was generally low (below 5%) except in Zimbabwe (30% among women, 11.7% among men). Prevalence of bacterial STDs was generally low (below 5% for gonorrhea and under 7% for syphilis in all sites), with the exception of syphilis among female sex workers in India. Behavioral and demographic risks for STDs varied widely across the five study sites. Common risks for STDs included female gender, increasing number of recent sex partners, and in some sites, older age, particularly for chronic STDs (i.e., HSV-2 and HIV). Prevalence of HIV was not associated with STDs except in Zimbabwe, which showed a modest correlation between HIV and HSV-2 prevalence (Pearson coefficient = .55). These findings underscore the heterogeneity of global STD and HIV epidemics and suggest that local, focused interventions are needed to achieve significant declines in these infections.

Sit-to-stand (STD) and stand-to-sit (SIT) analysis can provide information on functional independence in daily activities in patients with low back pain (LBP). However, in order for measurements to be clinically useful, data on psychometric properties should be available. The main purpose was to investigate intra-rater reliability of STD and SIT tasks in participants with and without chronic non-specific LBP (CNLBP). The second purpose was to detect any differences in lumbar spine and hips sagittal plane kinematics and coordination between asymptomatic individuals and CNLBP patients during STD and SIT. Cross-sectional study. Twenty-three CNLBP patients and 23 demographically-matched controls were recruited. Ten markers were placed on specific anatomical landmarks. Participants were asked to perform STD and SIT at a preferred speed. Peak flexion angles, mean angular velocities, lumbar to hip movement ratios, and relative phase angles were measured. The procedure was repeated after 2 h and 6-8 days. Differences between two groups were analyzed using independent t-test. Intraclass correlation coefficient (ICC 3,k), standard error of measurement (SEM), and limits of agreement (LOAs) were also estimated. The ICC values showed moderate to excellent intra-rater reliability, with relatively low SEM values (≤10.17°). The 95% LOAs demonstrated that there were no differences between the measured parameters. Furthermore, CNLBP patients had limited sagittal plane angles, smaller angular velocities, and lumbar-hip dis-coordination compared to asymptomatic participants. The results indicated moderate to excellent test-retest reliability of STD and SIT analysis. Moreover, CNLBP patients had altered kinematics during STD and its reverse. Copyright © 2017 Elsevier Ltd.

Dose of Dialysis Based on Body Surface Area Is Markedly Less in Younger Children Than in Older Adolescents

PubMed Central

Hanna, Melisha G.; Becker-Cohen, Rachel; Langman, Craig B.

2010-01-01

Background and observations: The current denominator for dosing dialysis is the urea distribution volume (V). Normalizing Kt/V to body surface area (S) has been proposed, but the implications of doing this in children have not been examined. Design, setting, participants, & measurements: Dialysis dose given to children and adolescents was calculated in terms of conventional V-based scaling and surface-area-normalized standard Kt/V (SAN-stdKt/V) calculated as stdKt/V·(Vant/S)/17.5, where Vant was an anthropometric estimate of V calculated using the Morgenstern equation. Formal 2-pool modeling was used to compute all dialysis adequacy outputs. Results: In 34 children (11 girls, 23 boys) dialyzed 3 times a week, age range 1.4 to 18 years, the mean delivered equilibrated Kt/V (eKt/V) was 1.40, and the mean stdKt/V was 2.49, both of which tended to be higher in younger children. The ratio of Vant to S was 15.6 ± 2.69 and was strongly associated with age between ages 2 and 16. SAN-stdKt/V averaged 2.21 and was strongly correlated with age between ages 2 and 16. If one considers a desired target for SAN-stdKt/V to be 2.45, all children less than 10 years of age were below target, despite having relatively high values of eKt/V and stdKt/V. Conclusions: If a surface-area-based denominator were to be adopted for dialysis dosing, most children under 10 years of age would receive markedly less dialysis than adolescent patients and would require 6- to 8-hour hemodialysis sessions or, for the youngest children, treatments given more frequently than 3 times/wk.

The following position paper will describe DOE-STD-3013 container sets No.L000072 and No.L000076, and how they are compliant with DOE-STD-3013-2004. All masses of accountable nuclear materials are measured on LLNL certified balances maintained under an MC&A Program approved by DOE/NNSA LSO. All accountability balances are recalibrated annually and checked to be within calibration on each day that the balance is used for accountability purposes. A statistical analysis of the historical calibration checks from the last seven years indicates that the full-range Limit of Error (LoE, 95% confidence level) for the balance used to measure the mass of the contents of themore » above indicated 3013 containers is 0.185 g. If this error envelope, at the 95% confidence level, were to be used to generate an upper-limit to the measured weight of the containers No.L000072 and No.L000076, the error-envelope would extend beyond the 5.0 kg 3013-standard limit on the package contents by less than 0.3 g. However, this is still well within the intended safety bounds of DOE-STD-3013-2004.« less

Relationships between perceived STD-related stigma, STD-related shame and STD screening among a household sample of adolescents.

PubMed

Cunningham, Shayna D; Kerrigan, Deanna L; Jennings, Jacky M; Ellen, Jonathan M

2009-12-01

Important barriers to STD testing may include individuals' perceptions of STD-related stigma (negative societal attitudes toward STD infection) and expectations of STD-related shame (negative personal feelings) that would result from a positive STD test. Obtaining a clear understanding of the relationship between STD-related stigma, STD-related shame and STD testing may help inform programs and policies aimed at reducing STD transmission. Measures derived from previously published scales were used to assess perceived STD-related stigma, anticipated STD-related shame and receipt of an STD test in the past year in an urban, household sample of 594 sexually active 15-24-year-olds interviewed in 2004-2007. Logistic regression was used to examine associations between recent STD testing and perceived stigma, shame and other participant characteristics. Thirty-seven percent of males and 70% of females reporting having had an STD test in the past year; the largest proportions of tests (42% among males and 59% among females) had occurred in the context of a routine health care visit, not because adolescents had had disease symptoms or were concerned about exposure to infection. For both males and females, the level of STD-related stigma was negatively associated with the odds of having been tested (odds ratio, 0.5 for each). STD-related shame was not related to STD testing. Adolescents who view STDs as stigmatizing have a reduced likelihood of being screened, but it is unclear whether this relationship reflects their care seeking or providers' practice of offering STD screening at a routine health visit.

How restful is it with all that noise? Comparison of Interleaved silent steady state (ISSS) and conventional imaging in resting-state fMRI.

Resting-state fMRI studies have become very important in cognitive neuroscience because they are able to identify BOLD fluctuations in brain circuits involved in motor, cognitive, or perceptual processes without the use of an explicit task. Such approaches have been fruitful when applied to various disordered populations, or to children or the elderly. However, insufficient attention has been paid to the consequences of the loud acoustic scanner noise associated with conventional fMRI acquisition, which could be an important confounding factor affecting auditory and/or cognitive networks in resting-state fMRI. Several approaches have been developed to mitigate the effects of acoustic noise on fMRI signals, including sparse sampling protocols and interleaved silent steady state (ISSS) acquisition methods, the latter being used only for task-based fMRI. Here, we developed an ISSS protocol for resting-state fMRI (rs-ISSS) consisting of rapid acquisition of a set of echo planar imaging volumes following each silent period, during which the steady state longitudinal magnetization was maintained with a train of relatively silent slice-selective excitation pulses. We evaluated the test-retest reliability of intensity and spatial extent of connectivity networks of fMRI BOLD signal across three different days for rs-ISSS and compared it with a standard resting-state fMRI (rs-STD). We also compared the strength and distribution of connectivity networks between rs-ISSS and rs-STD. We found that both rs-ISSS and rs-STD showed high reproducibility of fMRI signal across days. In addition, rs-ISSS showed a more robust pattern of functional connectivity within the somatosensory and motor networks, as well as an auditory network compared with rs-STD. An increased connectivity between the default mode network and the language network and with the anterior cingulate cortex (ACC) network was also found for rs-ISSS compared with rs-STD. Finally, region of interest analysis showed higher interhemispheric connectivity in Heschl's gyri in rs-ISSS compared with rs-STD, with lower variability across days. The present findings suggest that rs-ISSS may be advantageous for detecting network connectivity in a less noisy environment, and that resting-state studies carried out with standard scanning protocols should consider the potential effects of loud noise on the measured networks.

Implementation of Ada protocols on Mil-STD-1553 B data bus

NASA Technical Reports Server (NTRS)

Ruhman, Smil; Rosemberg, Flavia

1986-01-01

Standardization activity of data communication in avionic systems started in 1968 for the purpose of total system integration and the elimination of heavy wire bundles carrying signals between various subassemblies. The growing complexity of avionic systems is straining the capabilities of MIL-STD-1553 B (first issued in 1973), but a much greater challenge to it is posed by Ada, the standard language adopted for real-time, computer embedded-systems. Hardware implementation of Ada communication protocols in a contention/token bus or token ring network is proposed. However, during the transition period when the current command/response multiplex data bus is still flourishing and the development environment for distributed multi-computer Ada systems is as yet lacking, a temporary accomodation of the standard language with the standard bus could be very useful and even highly desirable. By concentrating all status informtion and decisions at the bus controller, it was found to be possible to construct an elegant and efficient harware impelementation of the Ada protocols at the bus interface. This solution is discussed.

In the past there have been efforts by the U.S. Department of Energy (DOE) to provide guidance on those elements that should be included in a facility`s safety analysis report (SAR). In particular, there are two DOE Orders (5480.23, {open_quotes}Nuclear Safety Analysis Reports,{close_quotes} and 5480.24, {open_quotes}Nuclear Criticality Safety{close_quotes}), an interpretive guidance document (NE-70, Interpretive Guidance for DOE Order 5480.24, {open_quotes}Nuclear Criticality Safety{close_quotes}), and DOE Standard DOE-STD-3009-94 {open_quotes}Preparation Guide for U.S. Department of Energy Nonreactor Nuclear Facility Safety Analysis Reports.{close_quotes} Of these, the most practical and useful (pertaining to the application of criticality safety) is DOE-STD-3009-94. This paper is a reviewmore » of Chapters 3, 4, and 6 of this standard and how they provide very clear, helpful, and reasoned criticality safety guidance.« less

Crosstalk between virulence loci: regulation of Salmonella enterica pathogenicity island 1 (SPI-1) by products of the std fimbrial operon.

PubMed

López-Garrido, Javier; Casadesús, Josep

2012-01-01

Invasion of intestinal epithelial cells is a critical step in Salmonella infection and requires the expression of genes located in Salmonella pathogenicity island 1 (SPI-1). A key factor for SPI-1 expression is DNA adenine (Dam) methylation, which activates synthesis of the SPI-1 transcriptional activator HilD. Dam-dependent regulation of hilD is postranscriptional (and therefore indirect), indicating the involvement of unknown cell functions under Dam methylation control. A genetic screen has identified the std fimbrial operon as the missing link between Dam methylation and SPI-1. We show that all genes in the std operon are part of a single transcriptional unit, and describe three previously uncharacterized ORFs (renamed stdD, stdE, and stdF). We present evidence that two such loci (stdE and stdF) are involved in Dam-dependent control of Salmonella SPI-1: in a Dam(-) background, deletion of stdE or stdF suppresses SPI-1 repression; in a Dam(+) background, constitutive expression of StdE and/or StdF represses SPI-1. Repression of SPI-1 by products of std operon explains the invasion defect of Salmonella Dam(-) mutants, which constitutively express the std operon. Dam-dependent repression of std in the ileum may be required to permit invasion, as indicated by two observations: constitutive expression of StdE and StdF reduces invasion of epithelial cells in vitro (1,000 fold) and attenuates Salmonella virulence in the mouse model (>60 fold). In turn, crosstalk between std and SPI-1 may play a role in intestinal infections by preventing expression of SPI-1 in the caecum, an intestinal compartment in which the std operon is known to be expressed.

Opioid abuse is a major problem around the world. Identifying environmental factors that contribute to opioid abuse and addiction is necessary for decreasing this epidemic. In rodents, environmental enrichment protects against the development of low dose stimulant self-administration, but studies examining the effect of enrichment and isolation (compared to standard housing) on the development of intravenous opioid self-administration have not been conducted. The present study investigated the role of environmental enrichment on self-administration of the short-acting μ-opioid remifentanil. Rats were raised in an enriched condition (Enr), standard condition (Std), or isolated condition (Iso) beginning at 21 days of age and were trained to lever press for 1 or 3 μg/kg/infusion remifentanil in young adulthood. Acquisition of self-administration and responding during increasing fixed ratio requirements were assessed, and a dose-response curve was generated. In all phases, Enr rats lever pressed significantly less than Std and Iso rats, with Enr rats pressing between 9 and 40% the amount of Iso rats. Enr rats did not acquire remifentanil self-administration when trained with 1 μg/kg/infusion, did not increase responding over increasing FR when trained at either dose, and their dose-response curves were flattened compared to Std and Iso rats. When expressed as economic demand curves, Enr rats displayed a decrease in both essential value (higher α) and reinforcer intensity (Q 0 ) compared to Std and Iso rats at the 1 μg/kg/infusion training dose. Environmental enrichment reduced remifentanil intake, suggesting that social and environmental novelty may protect against opioid abuse.

BACKGROUND Sexually Transmitted Diseases are still considered a serious public health problem in Brazil and worldwide. OBJECTIVE To examine Sexually Transmitted Diseases prevalence and the sickness impact profile of STDs in a reference health center specializing in the treatment of Sexually Transmitted Diseases. METHOD We collected epidemiological, demographic, clinical and laboratory data from the medical records and interviews of 4,128 patients who had attended the center from January 1999 to December 2009. RESULTS Male patients outnumbered (76%) females (24%), Caucasians outnumbered (74.3%) those of mixed race (14.8%), blacks (10.8%) and Asians (0.1%). STD occurrence was higher in the 20-29 age group (46.2%) This population included 34.7% high school graduates, 8.7% college graduates and 0.8% illiterates. As for affective-sexual orientation, 86.5% were heterosexual, 7.8% homosexual and 5.5% bisexual. Regarding patients' sexual practices over the previous 30 days, 67.7% reported sexual intercourse with one person, 8.6% had had sex with two persons and 3.9%, with three or more people. The highest incidence of STD was condyloma acuminata, affecting 29.4% of all the patients, genital candidiasis 14.2%, and genital herpes 10.6%. Of the 44.3% who submitted to serologic testing for HIV detection 5% were positive, with a ratio of 6.8 males to 1 female. CONCLUSIONS STD prevalence remains high in Brazil and it is necessary to invest in early detection, prevention and treatment. PMID:24068122

2004-07-01

The OrbiSac device, which was developed to automate the manufacture of buffy-coat PLT concentrates (BC-PCs), was evaluated. In-vitro characteristics of BC-PC preparations using the OrbiSac device were compared with manually prepared BC-PCs. For standard processing (Std-PC, n = 20), four BC-PCs were pooled using 300 mL of PLT AS (PAS) followed by soft-spin centrifugation and WBC filtration. The OrbiSac preparation (OS-PC, n = 20) was performed by automated pooling of four BC-PCs with 300 mL PAS followed by centrifugation and inline WBC filtration. All PCs were stored at 22 degrees C. Samples were withdrawn on Day 1, 5, and 7 evaluating PTL count, blood gas analysis, glucose, lactate, LDH, beta-thromboglobulin, hypotonic shock response, and CD62p expression. A PLT content of 3.1 +/- 0.4 x 10(11) (OS-PCs) versus 2.7 +/- 0.5 x 10(11) (Std-PCs, p < 0.05) was found. A CV of 19 percent (Std-PC) versus 14 percent (OS-PC) suggests more standardization in the OS group. At Day 7, the Std-PCs versus OS-PCs showed a glucose consumption of 1.03 +/- 0.32 micro mol per 10(9) PLT versus 0.75 +/- 0.25 micro mol per 10(9) PLT (p < 0.001), and a lactate production of 1.50 +/- 0.86 micro mol per 10(9) versus 1.11 +/- 0.61 micro mol per 10(9) (p < 0.001). The pH (7.00 +/- 0.19 vs. 7.23 +/- 0.06; p < 0.001), pO(2) (45.3 +/- 18 vs. 31.3 +/- 10.4 mmHg; p < 0.01), and HCO(3) levels (4.91 +/- 1.49 vs. 7.14 +/- 0.95 mmol/L; p < 0.001) suggest a slightly better aerobic metabolism within the OS group. Only small differences in CD62p expression was observed (37.3 +/- 12.9% Std-PC vs. 44.8 +/- 6.6% OS-PC; p < 0.05). The OrbiSac device allows an improved PLT yield without affecting PLT in-vitro characteristics and may enable an improved consistency in product volume and yield.

This study evaluated the relative efficacy of strategies for the prevention of multidrug-resistant gram-negative bacteria (MDR-GNB) in adult intensive care units (ICUs). A systematic review and network meta-analysis was performed; searches of the Cochrane Library, PubMed, Embase, and CINAHL (Cumulative Index to Nursing and Allied Health Literature) included all randomized controlled trials and observational studies conducted in adult patients hospitalized in ICUs and evaluating standard care (STD), antimicrobial stewardship program (ASP), environmental cleaning (ENV), decolonization methods (DCL), or source control (SCT), simultaneously. The primary outcomes were MDR-GNB acquisition, colonization, and infection; secondary outcome was ICU mortality. Of 3805 publications retrieved, 42 met inclusion criteria (5 randomized controlled trials and 37 observational studies), involving 62068 patients (median age, 58.8 years; median APACHE [Acute Physiology and Chronic Health Evaluation] II score, 18.9). The majority of studies reported extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae and MDR Acinetobacter baumannii. Compared with STD, a 4-component strategy composed of STD, ASP, ENV, and SCT was the most effective intervention (rate ratio [RR], 0.05 [95% confidence interval {CI}, .01-.38]). When ENV was added to STD+ASP or SCT was added to STD+ENV, there was a significant reduction in the acquisition of MDR A. baumannii (RR, 0.28 [95% CI, .18-.43] and 0.48 [95% CI, .35-.66], respectively). Strategies with ASP as a core component showed a statistically significant reduction the acquisition of ESBL-producing Enterobacteriaceae (RR, 0.28 [95% CI, .11-.69] for STD+ASP+ENV and 0.23 [95% CI, .07-.80] for STD+ASP+DCL). A 4-component strategy was the most effective intervention to prevent MDR-GNB acquisition. As some strategies were differential for certain bacteria, our study highlighted the need for further evaluation of the most effective prevention strategies. © The Author 2017.

Military applications of emission and susceptibility data

NASA Astrophysics Data System (ADS)

Kohlbacher, Howard; Walker, William

A basic design consideration for new military communications-electronics (C-E) equipment is that it be electromagnetically compatible with the environment in which it will operate. A military standard (MIL-STD-461B) describes the design requirements for the control of the unintentional electromagnetic emission and susceptibility characteristics of electronic equipment and subsystems designed or procured by the US Department of Defense. For new systems which fail the test standards of MIL-STD-461B with regard to radiated susceptibility (RSO3) or radiated emissions (RE02), a decision must be made to fix the new system or to field it without a fix. A procedure to aid in the decision process is outlined. The minimum separation distances required between a failed test system and other C-E equipment in its environment to avoid interference are determined. If this distance is operationally acceptable, the failed unit may be considered to be operationally compatible with its electromagnetic environment.

Wheeler, M. L.

1998-01-01

The objective of this test guide is to document appropriate unit level test methods and techniques for the performance of EMI testing of Direct Sequence (DS) spread spectrum receivers. Consideration of EMI test methods tailored for spread spectrum receivers utilizing frequency spreading, techniques other than direct sequence (such as frequency hopping, frequency chirping, and various hybrid methods) is beyond the scope of this test guide development program and is not addressed as part of this document EMI test requirements for NASA programs are primarily developed based on the requirements contained in MIL-STD-46 1 D (or earlier revisions of MIL-STD-46 1). The corresponding test method guidelines for the MIL-STD-461 D tests are provided in MIL-STD-462D. These test methods are well documented with the exception of the receiver antenna port susceptibility tests (intermodulation, cross modulation, and rejection of undesired signals) which must be tailored to the specific type of receiver that is being tested. Thus, test methods addressed in this guide consist only of antenna port tests designed to evaluate receiver susceptibility characteristics. MIL-STD-462D should be referred for guidance pertaining to test methods for EMI tests other than the antenna port tests. The scope of this test guide includes: (1) a discussion of generic DS receiver performance characteristics; (2) a summary of S-band TDRSS receiver operation; (3) a discussion of DS receiver EMI susceptibility mechanisms and characteristics; (4) a summary of military standard test guidelines; (5) recommended test approach and methods; and (6) general conclusions and recommendations for future studies in the area of spread spectrum receiver testing.

Sexual dimorphism of the suprascapular notch – morphometric study

PubMed Central

Jędrzejewski, Kazimierz S.; Topol, Mirosław

2013-01-01

Introduction The concept of the study was to compare the morphometry of the suprascapular notch (SSN) in females and males because its size and shape may be a factor in suprascapular nerve entrapment. Material and methods The measurements of 81 scapulae included morphological length and width, maximal width and length projection of the scapular spine, and width and length of the glenoid cavity. The width-length scapular and glenoid cavity indices were calculated. In addition to standard anthropometric measurements three other dimensions were defined and collected for every SSN: maximal depth (MD), superior (STD) and middle (MTD) transverse diameters. Results The analysis of the measurements allowed us to distinguish five types of SSN. Type I (26%) had longer maximal depth than superior transverse diameter. Type II (3%) had equal MD, STD and MTD. In type III (57.6%) superior transverse diameter was longer than maximal depth. In type IV (7.4%) a bony foramen was present. Type V (6%) was without a discrete notch. Types I and III were divided into two subtypes: A (MTD was longer than STD) and B (MTD < STD). Distribution of the suprascapular notch types in both sexes was similar. However, MD, STD and MTD were significantly higher in males. The superior transverse suprascapular ligament was completely and partially ossified in 7.4% and 24.7% respectively. Conclusions The presented classification of the suprascapular notch is simple, easy to use, and based on specific geometric parameters which allow one to clearly distinguish five types of these structures. All dimensions of SSN were significantly higher in males than in females. PMID:23515320

We assessed the characteristics of sexually transmitted disease (STD) clinic patients, their reasons for seeking health services in STD clinics, and their access to health care in other venues. In 2013, we surveyed persons who used publicly funded STD clinics in 21 US cities with the highest STD morbidity. Of the 4364 STD clinic patients we surveyed, 58.5% were younger than 30 years, 72.5% were non-White, and 49.9% were uninsured. They visited the clinic for STD symptoms (18.9%), STD screening (33.8%), and HIV testing (13.6%). Patients chose STD clinics because of walk-in, same-day appointments (49.5%), low cost (23.9%), and expert care (8.3%). Among STD clinic patients, 60.4% had access to another type of venue for sick care, and 58.5% had access to another type of venue for preventive care. Most insured patients (51.6%) were willing to use insurance to pay for care at the STD clinic. Despite access to other health care settings, patients chose STD clinics for sexual health care because of convenient, low-cost, and expert care. Policy Implication. STD clinics play an important role in STD prevention by offering walk-in care to uninsured patients.

Comparability on knowledge, attitudes, and behaviors between STD clinic clients and high-risk individuals in community.

Du, Ping; Thomas, Rosalind; McNutt, Louise-Anne; Bruce Coles, F

2008-01-01

To assess the feasibility and generalizability of STD clinic samples for studying STD-related knowledge, attitudes, and behaviors (KAB), and healthcare preferences among individuals at high risk for STDs in the same community. An STD clinic and a community sample were selected from each of two urban areas in New York State. At each STD clinic, 100 individuals were interviewed. In each community, about 400 individuals were selected by random-digit-dialing telephone survey during the same period. Community sample participants were defined as having high-risk profiles on the basis of five items related to their sexual behaviors. The STD clinic samples were younger and had a larger proportion of men and nonwhite people compared with the high-risk community samples. Although the majority of STD clinic clients would seek healthcare at the STD clinics, high-risk community participants were more likely to prefer private doctors for STDs care (P < .0001 for both areas). Overall STD-related KAB were similar between STD clinic and high-risk community samples; however, STD clinic clients may be more knowledgeable about specific STDs and more likely to feel embarrassment about getting an STD. The findings comparing KAB between high-risk community subjects and STD clinic attendees also varied by geographic location. STD clinic samples may not be sufficiently representative of community STD-related KAB collected by telephone surveys, even for that subset of community respondents with high-risk behaviors associated with STDs.

The purpose of the study was to examine the association between adolescents' psychological distress and their sexually transmitted disease/human immunodeficiency virus (STD/HIV)-associated sexual behaviors and attitudes. Sexually active black adolescent females (N = 522) completed, at baseline and again 6 months later, a self-administered questionnaire that assessed sexual health attitudes and emotional distress symptoms (using standardized measures, alpha =.84), a structured interview that assessed STD/HIV-associated sexual risk behaviors, and a urine screen for pregnancy. In multivariate analyses, controlling for observed covariates, adolescents with significant distress at baseline were more likely than their peers, after 6 months, to be pregnant (adjusted odds ratio [AOR]: = 2.0), have had unprotected vaginal sex (AOR = 2.1), have nonmonogamous sex partners (AOR = 1.7), and not use any form of contraception (AOR = 1.5). Additionally, they were also more likely to: perceive barriers to condom use (AOR = 2.2), be fearful of the adverse consequences of negotiating condom use (AOR = 2.0), perceive less control in their relationship (AOR = 2.0), have experienced dating violence (AOR = 2.4), feel less efficacious in negotiating condom use with a new sex partner (AOR = 1.6), and have norms nonsupportive of a healthy sexual relationship (AOR = 1.7). The findings suggest that psychological distress is predictive over a 6-month period of a spectrum of STD/HIV-associated sexual behaviors and high-risk attitudes. Brief screening to detect distress or depressive symptoms among adolescent females can alert the clinician to the need to conduct a sexual health history, initiate STD/HIV-preventive counseling, and refer for comprehensive psychological assessment and appropriate treatment. Among adolescents receiving STD treatment, those with even moderate emotional distress may be at heightened risk for further unhealthy outcomes. STD/HIV interventions should also consider psychological distress as one potential risk factor that may impact program efficacy.

Objectives. We assessed the characteristics of sexually transmitted disease (STD) clinic patients, their reasons for seeking health services in STD clinics, and their access to health care in other venues. Methods. In 2013, we surveyed persons who used publicly funded STD clinics in 21 US cities with the highest STD morbidity. Results. Of the 4364 STD clinic patients we surveyed, 58.5% were younger than 30 years, 72.5% were non-White, and 49.9% were uninsured. They visited the clinic for STD symptoms (18.9%), STD screening (33.8%), and HIV testing (13.6%). Patients chose STD clinics because of walk-in, same-day appointments (49.5%), low cost (23.9%), and expert care (8.3%). Among STD clinic patients, 60.4% had access to another type of venue for sick care, and 58.5% had access to another type of venue for preventive care. Most insured patients (51.6%) were willing to use insurance to pay for care at the STD clinic. Conclusions. Despite access to other health care settings, patients chose STD clinics for sexual health care because of convenient, low-cost, and expert care. Policy Implication. STD clinics play an important role in STD prevention by offering walk-in care to uninsured patients. PMID:26447908

Washington Safety Management Solutions (WSMS) provides criticality safety services to Washington Savannah River Company (WSRC) at the Savannah River Site. One activity at SRS is the Container Surveillance and Storage Capability (CSSC) Project, which will perform surveillances on 3013 containers (hereafter referred to as 3013s) to verify that they meet the Department of Energy (DOE) Standard (STD) 3013 for plutonium storage. The project will handle quantities of material that are greater than ANS/ANSI-8.1 single parameter mass limits, and thus required a Nuclear Criticality Safety Evaluation (NCSE). The WSMS methodology for conducting an NCSE is outlined in the WSMS methods manual.more » The WSMS methods manual currently follows the requirements of DOE-O-420.1B, DOE-STD-3007-2007, and the Washington Savannah River Company (WSRC) SCD-3 manual. DOE-STD-3007-2007 describes how a NCSE should be performed, while DOE-O-420.1B outlines the requirements for a Criticality Safety Program (CSP). The WSRC SCD-3 manual implements DOE requirements and ANS standards. NCSEs do not address the Nuclear Criticality Safety (NCS) of non-reactor nuclear facilities that may be affected by overt or covert activities of sabotage, espionage, terrorism or other security malevolence.

Drop Testing Representative Multi-Canister Overpacks

DOE Office of Scientific and Technical Information (OSTI.GOV)

Snow, Spencer D.; Morton, Dana K.

The objective of the work reported herein was to determine the ability of the Multi- Canister Overpack (MCO) canister design to maintain its containment boundary after an accidental drop event. Two test MCO canisters were assembled at Hanford, prepared for testing at the Idaho National Engineering and Environmental Laboratory (INEEL), drop tested at Sandia National Laboratories, and evaluated back at the INEEL. In addition to the actual testing efforts, finite element plastic analysis techniques were used to make both pre-test and post-test predictions of the test MCOs structural deformations. The completed effort has demonstrated that the canister design is capablemore » of maintaining a 50 psig pressure boundary after drop testing. Based on helium leak testing methods, one test MCO was determined to have a leakage rate not greater than 1x10 -5 std cc/sec (prior internal helium presence prevented a more rigorous test) and the remaining test MCO had a measured leakage rate less than 1x10 -7 std cc/sec (i.e., a leaktight containment) after the drop test. The effort has also demonstrated the capability of finite element methods using plastic analysis techniques to accurately predict the structural deformations of canisters subjected to an accidental drop event.« less

Technical basis for inner container leak detection sensitivity goals in 3013 DE surveillance

DOE Office of Scientific and Technical Information (OSTI.GOV)

Berg, John M.

Helium leak checking of 3013 inner container lids is under consideration for addition to DE Surveillance tasks as an improved means to detect any through-wall flaws that may have formed during storage. This white paper evaluates whether leak checking at DE could replace and improve upon the current method of comparing gas compositions and pressures within the inner and outer containers. We have used viscous and molecular flow equations in ANSI N14.5 to calculate what the measured standard helium leak rate would be for hypothetical leaks of three different sizes. For comparison, we have also calculated the effects on gasmore » composition and pressure differences as a function of pre-DE storage time for the same three leak sizes, using molecular and viscous flow equations as well as diffusion equations to predict the relevant gas transport. For a hypothetical leak that would be measured at 1x10 -7 std cc/sec, likely an achievable sensitivity using helium leak checking at DE, the calculations predict no measurable effect on pressure difference or gas composition as measured by DE gas analysis. We also calculate that it would take over 200 years for water vapor to diffuse through a 10 -7 std cc/sec leak enough to raise the RH outer container to half the RH value in the inner container. A leak 100 times larger, which would be measured at 1x10 -5 std cc/sec, the same water vapor diffusion would take at least 14 years. Our conclusion is that helium leak checking will be useful even at a sensitivity of 1x10 -5 std cc/sec, and a significant improvement over current DE methods at a sensitivity of 1x10 -7 std cc/sec.« less

Comparison of computational to human observer detection for evaluation of CT low dose iterative reconstruction

NASA Astrophysics Data System (ADS)

Eck, Brendan; Fahmi, Rachid; Brown, Kevin M.; Raihani, Nilgoun; Wilson, David L.

2014-03-01

Model observers were created and compared to human observers for the detection of low contrast targets in computed tomography (CT) images reconstructed with an advanced, knowledge-based, iterative image reconstruction method for low x-ray dose imaging. A 5-channel Laguerre-Gauss Hotelling Observer (CHO) was used with internal noise added to the decision variable (DV) and/or channel outputs (CO). Models were defined by parameters: (k1) DV-noise with standard deviation (std) proportional to DV std; (k2) DV-noise with constant std; (k3) CO-noise with constant std across channels; and (k4) CO-noise in each channel with std proportional to CO variance. Four-alternative forced choice (4AFC) human observer studies were performed on sub-images extracted from phantom images with and without a "pin" target. Model parameters were estimated using maximum likelihood comparison to human probability correct (PC) data. PC in human and all model observers increased with dose, contrast, and size, and was much higher for advanced iterative reconstruction (IMR) as compared to filtered back projection (FBP). Detection in IMR was better than FPB at 1/3 dose, suggesting significant dose savings. Model(k1,k2,k3,k4) gave the best overall fit to humans across independent variables (dose, size, contrast, and reconstruction) at fixed display window. However Model(k1) performed better when considering model complexity using the Akaike information criterion. Model(k1) fit the extraordinary detectability difference between IMR and FBP, despite the different noise quality. It is anticipated that the model observer will predict results from iterative reconstruction methods having similar noise characteristics, enabling rapid comparison of methods.

EFFECTS OF A HIGH SATURATED FAT DIET ON CARDIAC HYPERTROPHY AND DYSFUNCTION IN RESPONSE TO PRESSURE OVERLOAD

PubMed Central

Chess, David; Lei, Biao; Hoit, Brian; Azimzadeh, Agnes M.; Stanley, William

2009-01-01

Background Dietary lipid content effects activation of peroxisome proliferator-activated receptor-α (PPARα) and may accelerate cardiac hypertrophy and dysfunction in response to pressure overload. This study investigated the effects of a high fat diet on the development of cardiac hypertrophy. Methods and Results C57BL/6J mice (n=14–16/group) underwent transverse aortic constriction (TAC) or sham surgery and were fed either standard low fat diet (STD; 10% fat) or a high fat diet (HFD; 60% fat) for 16 weeks. Sham mice showed no differences between STD and HFD for heart mass or echocardiographic parameters despite greater plasma free fatty acid and leptin concentrations with HFD. TAC increased heart mass and decreased ejection fraction similarly in both groups. Left ventricular end systolic and diastolic diameters with TAC were increased compared to shams on the HFD (p < 0.05) but were not different from STD TAC mice. High fat feeding increased expression of PPARα-regulated genes. The activity of medium chain acyl-coenzyme A dehydrogenase (MCAD), a marker of fatty acid oxidation capacity, was increased in HFD TAC mice compared to STD, consistent with PPARα activation. Conclusion Increased fat intake prevented the fall in MCAD activity and did not exacerbate the hypertrophic response to TAC compared to a low-fat diet. PMID:18226777

Studies have shown that sexually transmitted disease (STD) rates are high in the incarcerated population. However, little is known about STD testing policies or practices in jails. To assess STD testing policies and practices in jails. The Division of STD Prevention developed and distributed an e-mail survey to 94 counties reporting more than 40 primary and secondary cases in 1996 or having cities with more than 200,000 persons. State and local STD program managers completed the assessment in collaboration with health departments and the main jail facilities in the selected counties. Most facilities (52-77%) had a policy for STD screening based only on symptoms or by arrestee request, and in these facilities, 0.2% to 6% of arrestees were tested. Facilities having a policy of offering routine testing tested only 3% to 45% of arrestees. Large facilities, facilities using public providers, and facilities routinely testing for syphilis using Stat RPR tested significantly more arrestees (P<0.05). Approximately half of the arrestees were released within 48 hours after intake, whereas 45% of facilities did not have STD testing results until after 48 hours. Most facilities had a policy for STD screening based only on symptoms or by arrestee request. Facilities having a policy of routine STD testing are not testing most of the arrestees. There is a small window (<48 hours) for STD testing and treatment before release. Smaller jails and facilities using private providers may need additional resources to increase STD testing levels. Correctional facilities should be considered an important setting for STD public health intervention where routine rapid STD screening and treatment on-site could be implemented.

JPL Thermal Design Modeling Philosophy and NASA-STD-7009 Standard for Models and Simulations - A Case Study

NASA Technical Reports Server (NTRS)

Avila, Arturo

2011-01-01

The Standard JPL thermal engineering practice prescribes worst-case methodologies for design. In this process, environmental and key uncertain thermal parameters (e.g., thermal blanket performance, interface conductance, optical properties) are stacked in a worst case fashion to yield the most hot- or cold-biased temperature. Thus, these simulations would represent the upper and lower bounds. This, effectively, represents JPL thermal design margin philosophy. Uncertainty in the margins and the absolute temperatures is usually estimated by sensitivity analyses and/or by comparing the worst-case results with "expected" results. Applicability of the analytical model for specific design purposes along with any temperature requirement violations are documented in peer and project design review material. In 2008, NASA released NASA-STD-7009, Standard for Models and Simulations. The scope of this standard covers the development and maintenance of models, the operation of simulations, the analysis of the results, training, recommended practices, the assessment of the Modeling and Simulation (M&S) credibility, and the reporting of the M&S results. The Mars Exploration Rover (MER) project thermal control system M&S activity was chosen as a case study determining whether JPL practice is in line with the standard and to identify areas of non-compliance. This paper summarizes the results and makes recommendations regarding the application of this standard to JPL thermal M&S practices.

Human Factors, Habitability and Environmental Health and the Human Integration Design Handbook. Volume 2

Houbec, Keith; Tillman, Barry; Connolly, Janis

2010-01-01

For decades, Space Life Sciences and NASA as an Agency have considered NASA-STD-3000, Man-Systems Integration Standards, a significant contribution to human spaceflight programs and to human-systems integration in general. The document has been referenced in numerous design standards both within NASA and by organizations throughout the world. With research program and project results being realized, advances in technology and new information in a variety of topic areas now available, the time arrived to update this extensive suite of requirements and design information. During the past several years, a multi-NASA center effort has been underway to write the update to NASA-STD-3000 with standards and design guidance that would be applicable to all future human spaceflight programs. NASA-STD-3001 - Volumes 1 and 2 - and the Human Integration Design Handbook (HIDH) were created. Volume 1, Crew Health, establishes NASA s spaceflight crew health standards for the pre-flight, in-flight, and post-flight phases of human spaceflight. Volume 2, Human Factors, Habitability and Environmental Health, focuses on the requirements of human-system integration and how the human crew interacts with other systems, and how the human and the system function together to accomplish the tasks for mission success. The HIDH is a compendium of human spaceflight history and knowledge, and provides useful background information and research findings. And as the HIDH is a stand-alone companion to the Standards, the maintenance of the document has been streamlined. This unique and flexible approach ensures that the content is current and addresses the fundamental advances of human performance and human capabilities and constraints research. Current work focuses on the development of new sections of Volume 2 and collecting updates to the HIDH. The new sections in development expand the scope of the standard and address mission operations and support operations. This effort is again collaboration with representatives from the Johnson Space Center Missions Operations and Space Life Sciences Directorates and the Engineering Directorate from Kennedy Space Center as well as discipline experts from across the Agency.

This review aims to illustrate that STD NMR is not simply a method for drug screening and discovery, but has qualitative and quantitative applications that can answer fundamental and applied biological and biomedical questions involving molecular interactions between ligands and proteins. We begin with a basic introduction to the technique of STD NMR and report on recent advances and biological applications of STD including studies to follow the interactions of non-steroidal anti-inflammatories, minimum binding requirements for virus infection and understating inhibition of amyloid fibre formation. We expand on this introduction by reporting recent STD NMR studies of live-cell receptor systems, new methodologies using scanning STD, magic-angle spinning STD and approaches to use STD NMR in a quantitative fashion for dissociation constants and group epitope mapping (GEM) determination. We finish by outlining new approaches that have potential to influence future applications of the technique; NMR isotope-editing, heteronuclear multidimensional STD and (19)F STD methods that are becoming more amenable due to the latest NMR equipment technologies.

Determinants of pain treatment response and nonresponse: identification of TMD patient subgroups.

PubMed

Litt, Mark D; Porto, Felipe B

2013-11-01

The purpose of the present study was to determine if we could identify a specific subtype of temporomandibular disorder (TMD) pain patients that does not respond to treatment. Patients were 101 men and women with chronic TMD pain recruited from the community and randomly assigned to 1 of 2 treatment conditions: a standard conservative care (STD) condition or a standard care plus cognitive-behavioral therapy condition (STD + CBT) in which patients received all elements of STD but also received cognitive-behavioral coping skills training. Growth mixture modeling, incorporating a series of treatment-related predictors, was used to distinguish several distinct classes of responders or nonresponders to treatment based on reported pain over a 1-year follow-up period. Results indicated that treatment nonresponders accounted for 16% of the sample and did not differ from treatment responders on demographics or temporomandibular joint pathology, but that they reported more psychiatric symptoms, poorer coping, and higher levels of catastrophizing. Treatment-related predictors of membership in treatment responder groups versus the nonresponder group included the addition of CBT to STD, treatment attendance, and decreasing catastrophization. It was concluded that CBT may be made more efficacious for TMD patients by placing further emphasis on decreasing catastrophization and on individualizing care. This article provides evidence that the TMD chronic pain population is heterogeneous and that a subsample of patients will be unresponsive to standard or psychosocial approaches. The addition of CBT to treatment may be helpful for this group, but new individualized approaches will be needed to treat all patients effectively. Copyright © 2013 American Pain Society.

Spaceflight Human System Standards

NASA Technical Reports Server (NTRS)

Holubec, Keith; Tillman, Barry; Connolly, Jan

2009-01-01

NASA created a new approach for human system integration and human performance standards. NASA created two documents a standard and a reference handbook. The standard is titled NASA Space Flight Human-System Standard (SFHSS) and consists of two-volumes: Volume 1- Crew Health This volume covers standards needed to support astronaut health (medical care, nutrition, sleep, exercise, etc.) Volume 2 Human Factors, Habitability and Environmental Health This volume covers the standards for system design that will maintain astronaut performance (ie., environmental factors, design of facilities, layout of workstations, and lighting requirements). It includes classic human factors requirements. The new standards document is written in terms so that it is applicable to a broad range of present and future NASA systems. The document states that all new programs prepare system-specific requirements that will meet the general standards. For example, the new standard does not specify a design should accommodate specific percentiles of a defined population. Rather, NASA-STD-3001, Volume 2 states that all programs shall prepare program-specific requirements that define the user population and their size ranges. The design shall then accommodate the full size range of those users. The companion reference handbook, Human Integration Design Handbook (HIDH), was developed to capture the design consideration information from NASA-STD-3000, and adds spaceflight lessons learned, gaps in knowledge, example solutions, and suggests research to further mature specific disciplines. The HIDH serves two major purposes: HIDH is the reference document for writing human factors requirements for specific systems. HIDH contains design guidance information that helps insure that designers create systems which safely and effectively accommodate the capabilities and limitations of space flight crews.

The effects of individualised perioperative lung-protective ventilation (based on the open-lung approach [OLA]) on postoperative complications is unknown. We aimed to investigate the effects of intraoperative and postoperative ventilatory management in patients scheduled for abdominal surgery, compared with standard protective ventilation. We did this prospective, multicentre, randomised controlled trial in 21 teaching hospitals in Spain. We enrolled patients who were aged 18 years or older, were scheduled to have abdominal surgery with an expected time of longer than 2 h, had intermediate-to-high-risk of developing postoperative pulmonary complications, and who had a body-mass index less than 35 kg/m 2 . Patients were randomly assigned (1:1:1:1) online to receive one of four lung-protective ventilation strategies using low tidal volume plus positive end-expiratory pressure (PEEP): open-lung approach (OLA)-iCPAP (individualised intraoperative ventilation [individualised PEEP after a lung recruitment manoeuvre] plus individualised postoperative continuous positive airway pressure [CPAP]), OLA-CPAP (intraoperative individualised ventilation plus postoperative CPAP), STD-CPAP (standard intraoperative ventilation plus postoperative CPAP), or STD-O 2 (standard intraoperative ventilation plus standard postoperative oxygen therapy). Patients were masked to treatment allocation. Investigators were not masked in the operating and postoperative rooms; after 24 h, data were given to a second investigator who was masked to allocations. The primary outcome was a composite of pulmonary and systemic complications during the first 7 postoperative days. We did the primary analysis using the modified intention-to-treat population. This trial is registered with ClinicalTrials.gov, number NCT02158923. Between Jan 2, 2015, and May 18, 2016, we enrolled 1012 eligible patients. Data were available for 967 patients, whom we included in the final analysis. Risk of pulmonary and systemic complications did not differ for patients in OLA-iCPAP (110 [46%] of 241, relative risk 0·89 [95% CI 0·74-1·07; p=0·25]), OLA-CPAP (111 [47%] of 238, 0·91 [0·76-1·09; p=0·35]), or STD-CPAP groups (118 [48%] of 244, 0·95 [0·80-1·14; p=0·65]) when compared with patients in the STD-O 2 group (125 [51%] of 244). Intraoperatively, PEEP was increased in 69 (14%) of patients in the standard perioperative ventilation groups because of hypoxaemia, and no patients from either of the OLA groups required rescue manoeuvres. In patients who have major abdominal surgery, the different perioperative open lung approaches tested in this study did not reduce the risk of postoperative complications when compared with standard lung-protective mechanical ventilation.

This study is a pharmacogenetic clinical trial designed to clarify whether the N-acetyltransferase 2 gene (NAT2) genotype-guided dosing of isoniazid improves the tolerability and efficacy of the 6-month four-drug standard regimen for newly diagnosed pulmonary tuberculosis. In a multicenter, parallel, randomized, and controlled trial with a PROBE design, patients were assigned to either conventional standard treatment (STD-treatment: approx. 5 mg/kg of isoniazid for all) or NAT2 genotype-guided treatment (PGx-treatment: approx. 7.5 mg/kg for patients homozygous for NAT2 4: rapid acetylators; 5 mg/kg, patients heterozygous for NAT2 4: intermediate acetylators; 2.5 mg/kg, patients without NAT2 4: slow acetylators). The primary outcome included incidences of 1) isoniazid-related liver injury (INH-DILI) during the first 8 weeks of therapy, and 2) early treatment failure as indicated by a persistent positive culture or no improvement in chest radiographs at the 8th week. One hundred and seventy-two Japanese patients (slow acetylators, 9.3 %; rapid acetylators, 53.5 %) were enrolled in this trial. In the intention-to-treat (ITT) analysis, INH-DILI occurred in 78 % of the slow acetylators in the STD-treatment, while none of the slow acetylators in the PGx-treatment experienced either INH-DILI or early treatment failure. Among the rapid acetylators, early treatment failure was observed with a significantly lower incidence rate in the PGx-treatment than in the STD-treatment (15.0 % vs. 38 %). Thus, the NAT2 genotype-guided regimen resulted in much lower incidences of unfavorable events, INH-DILI or early treatment failure, than the conventional standard regimen. Our results clearly indicate a great potential of the NAT2 genotype-guided dosing stratification of isoniazid in chemotherapy for tuberculosis.

The purpose of the Human Integration Design Processes (HIDP) document is to provide human-systems integration design processes, including methodologies and best practices that NASA has used to meet human systems and human rating requirements for developing crewed spacecraft. HIDP content is framed around human-centered design methodologies and processes in support of human-system integration requirements and human rating. NASA-STD-3001, Space Flight Human-System Standard, is a two-volume set of National Aeronautics and Space Administration (NASA) Agency-level standards established by the Office of the Chief Health and Medical Officer, directed at minimizing health and performance risks for flight crews in human space flight programs. Volume 1 of NASA-STD-3001, Crew Health, sets standards for fitness for duty, space flight permissible exposure limits, permissible outcome limits, levels of medical care, medical diagnosis, intervention, treatment and care, and countermeasures. Volume 2 of NASASTD- 3001, Human Factors, Habitability, and Environmental Health, focuses on human physical and cognitive capabilities and limitations and defines standards for spacecraft (including orbiters, habitats, and suits), internal environments, facilities, payloads, and related equipment, hardware, and software with which the crew interfaces during space operations. The NASA Procedural Requirements (NPR) 8705.2B, Human-Rating Requirements for Space Systems, specifies the Agency's human-rating processes, procedures, and requirements. The HIDP was written to share NASA's knowledge of processes directed toward achieving human certification of a spacecraft through implementation of human-systems integration requirements. Although the HIDP speaks directly to implementation of NASA-STD-3001 and NPR 8705.2B requirements, the human-centered design, evaluation, and design processes described in this document can be applied to any set of human-systems requirements and are independent of reference missions. The HIDP is a reference document that is intended to be used during the development of crewed space systems and operations to guide human-systems development process activities.

[Diagnosis and treatment of STDs].

Latif, A

Even though laboratory tests can easily diagnose sexually transmitted diseases (STDs), they require expensive, sophisticated equipment, which is lacking in many countries, and they take several days to obtain the results. In most cases, these tests require a sample for culture or the patient must be transferred to a hospital or an STD treatment center. Often patients do not want to return for test results or for treatment or they refuse to be transferred to another health facility. Thus, the STD goes untreated. The syndromic approach addresses these obstacles to STD diagnosis and treatment at the primary health care level. Nurses, midwives, health assistants, and clinical personnel undergo training in order to be able to diagnose and treat STDs during the first visit, at a reasonable cost, and without lab tests. They identify principal groups of signs and symptoms (i.e., syndromes) common to certain STDs. Prescribed drugs must be effective, cause no side effects, be available at the same center as the first consultation, and, preferably, be administered orally or by one dose. STD control programs need to identify the most prevalent syndromes and etiologic agents in the area and determine the most effective antibiotics for those syndromes. Donovanosis, syphilis, and soft chancre are responsible for genital ulcers in India and in Papua New Guinea; only syphilis and soft chancre are in other areas. Thus, it is important to provide treatment for all three causes in India and Papua New Guinea. It is easier to diagnose and treat penal discharge and genital ulcers in men and women than vaginal discharge and/or symptoms of pelvic inflammation in women. Thus, health workers need to ask a series of questions on risk factors for gonorrhea and chlamydia.

The widespread use of computed tomography (CT) has increased the medical radiation exposure and cancer risk. We aimed to evaluate the impact of AIDR 3D in CT abdomen-pelvic examinations based on image quality and radiation dose in low dose (LD) setting compared to standard dose (STD) with filtered back projection (FBP) reconstruction. We retrospectively reviewed the images of 40 patients who underwent CT abdomen-pelvic using a 80 slice CT scanner. Group 1 patients (n=20, mean age 41 ± 17 years) were performed at LD with AIDR 3D reconstruction and Group 2 patients (n=20, mean age 52 ± 21 years) were scanned with STD using FBP reconstruction. Objective image noise was assessed by region of interest (ROI) measurements in the liver and aorta as standard deviation (SD) of the attenuation value (Hounsfield Unit, HU) while subjective image quality was evaluated by two radiologists. Statistical analysis was used to compare the scan length, CT dose index volume (CTDIvol) and image quality of both patient groups. Although both groups have similar mean scan length, the CTDIvol significantly decreased by 38% in LD CT compared to STD CT (p<0.05). Objective and subjective image quality were statistically improved with AIDR 3D (p<0.05). In conclusion, AIDR 3D enables significant dose reduction of 38% with superior image quality in LD CT abdomen-pelvis.

By activating Fas/ceramide synthase 6/p38 kinase in lipid rafts, Stichoposide D inhibits growth of leukemia xenografts

Stichoposide D (STD) is a marine triterpene glycoside isolated from sea cucumbers. We examined the molecular mechanisms underlying the antitumor activity of STD in human leukemia cells. The role of Fas (CD95), ceramide synthase 6 (CerS6) and p38 kinase during STD-induced apoptosis was examined in human leukemia cells. In addition, the antitumor effects of STD in K562 and HL-60 leukemia xenograft models were investigated. We found that STD induces Fas translocation to lipid rafts, and thus mediates cell apoptosis. We also observed the activation of CerS6 and p38 kinase during STD-induced apoptosis. The use of methyl-β-cyclodextrin and nystatin to disrupt lipid rafts prevents the clustering of Fas and the activation of CerS6 and p38 kinase, and also inhibits STD-induced apoptosis. Specific inhibition by Fas, CerS6, and p38 kinase siRNA transfection partially blocked STD-induced apoptosis. In addition, STD has antitumor activity through the activation of CerS6 and p38 kinase without displaying any toxicity in HL-60 and K562 xenograft models. We observed that the anti-tumor effect of STD is partially prevented in CerS6 shRNA-silenced xenograft models. We first report that Fas/CerS6/p38 kinase activation in lipid rafts by STD is involved in its anti-leukemic activity. We also established that STD is able to enhance the chemosensitivity of K562 cells to etoposide or Ara-C. These data suggest that STD may be used alone or in combination with other chemotherapeutic agents to treat leukemia. PMID:26318294

From in vivo to in vitro: How the Guatemala STD Experiments Transformed Bodies Into Biospecimens.

PubMed

Spector-Bagdady, Kayte; Lombardo, Paul A

2018-06-01

Policy Points: While most scholarship regarding the US Public Health Service's STD experiments in Guatemala during the 1940s has focused on the intentional exposure experiments, secondary research was also conducted on biospecimens collected from these subjects. These biospecimen experiments continued after the Guatemala grant ended, and the specimens were used in conjunction with those from the Tuskegee syphilis experiments for ongoing research. We argue there should be a public accounting of whether there are still biospecimens from the Guatemala and Tuskegee experiments held in US government biorepositories today. If such specimens exist, they should be retired from US government research archives because they were collected unethically as understood at the time. The US Public Health Service's Guatemala STD experiments (1946-1948) included intentional exposure to pathogens and testing of postexposure prophylaxis methods for syphilis, gonorrhea, and chancroid in over 1,300 soldiers, commercial sex workers, prison inmates, and psychiatric patients. Though the experiments had officially ended, the biospecimens collected from these subjects continued to be used for research at least into the 1950s. We analyzed historical documents-including clinical and laboratory records, correspondence, final reports, and medical records-for information relevant to these biospecimen experiments from the US National Archives. In addition, we researched material from past governmental investigations into the Guatemala STD experiments, including those of the US Presidential Commission for the Study of Bioethical Issues and the Guatemalan Comisión Presidencial para el Esclarecimiento de los Experimentos Practicados con Humanos en Guatemala. Identified spinal fluid, blood specimens, and tissue collected during the Guatemala diagnostic methodology and intentional exposure experiments were subsequently distributed to laboratories throughout the United States for use in ongoing research until at least 1957. Five psychiatric patient subjects involved in these biospecimen experiments died soon after experimental exposure to STDs. The same US government researchers working with the Guatemala biospecimens after the exposure experiments ended were also working with specimens taken from the Tuskegee syphilis study. There should be a complete public accounting of whether biospecimens from the Guatemala and Tuskegee experiments are held in US government biorepositories today. If they still exist, these specimens should be retired from such biorepositories and their future disposition determined by stakeholders, including representatives from the communities from which they were derived. © 2018 Milbank Memorial Fund.

[Anonymous STD counselling versus mandatory checks for prostitutes--what is effective in STD prevention?].

PubMed

Nitschke, H; Ludwig-Diouf, B; Knappik, A; Leidel, J

2006-11-01

When in 2001 in Germany the new act for control of infectious diseases came into force, mandatory checks for prostitutes were abolished. The consequences of this paradigm shift in STD prevention are being judged controversially even today. The public health department of the city of Cologne, like others, adapted its programme, staff, equipment, and diagnostic procedures to the new requirements. The department for venereal disease control was converted into a walk-in-clinic for STD and now forms part of a comprehensive STD and Aids prevention unit. The present article illustrates the changes by comparing the clients and the STD numbers of the years 1994 and 2004. The following data were compared: number of consultations, number of clients regarding sex, occupation in sex business, health insurance, national or ethnic background, frequency of consultation, number of STD. In 1994, almost all clients of the department for venereal disease control were female prostitutes. 74% of them worked in established sex business venues with a high grade of professionalism, few STD cases were diagnosed. In 2004, the STD clinic was open for anybody considered to be at risk and not having access to the regular health care system. Only 49% of the patients were prostitutes, either female or male. 25% of the clients were male. 68% of the patients were migrants, many of them without any legal status and without any access to regular health care. A high number of acute STD and subsequent disorders that required treatment was registered. Besides the STD-related services, a great need for gynaecological and urological differential diagnostics as well as a high demand for counselling and provision of other problems of sexual health were observed. The data show that an STD department providing comprehensive services anonymously and free of charge will reach a broader range of highly vulnerable persons in comparison with an obligatory VD check of prostitutes. The high numbers of STD and STD-related disorders demonstrate the improved effectiveness of the new service.

Sexonomics: a commentary and review of selected sexually transmitted disease studies in the economics literature.

PubMed

Chesson, Harrell W

2012-03-01

The purpose of this review is to highlight selected studies in the economics literature that address sexually transmitted disease (STD)-related topics that are typically not examined in the STD literature. Two databases (EconLit and Web of Science) were searched to locate STD-related articles in the economics journals. Relevant articles were also identified in other ways, such as informal discussions with colleagues familiar with the literature. To maintain a focus on unique STD-related topics, studies with topics common in the STD literature (e.g., cost-effectiveness, transmission modeling) were excluded. Selected STD-related studies in the economics literature were grouped into the following 8 topics: impact of abortion laws and policies on sexual health outcomes; same-sex marriage and syphilis rates; alcohol policy and STD rates; welfare laws and STD rates; discounting the future; HIV disclosure laws; the impact of tolerance for gays on HIV incidence; and economic versus epidemiologic models of HIV dynamics. A general theme of STD-related studies in the economics literature is that laws and policies that increased the "cost" of risky sex tended to reduce the demand for risky sex, and therefore reduce the incidence of STDs. Economic research can contribute in novel ways to our understanding of influences on risky sexual behavior at the individual level and STD incidence at the population level. Economists and STD experts could mutually benefit from increased collaboration.

Background and objective Cardiovascular disease and type 2 diabetes pose a global health burden. Therefore, clarifying the pathology of these risk factors is essential. Previous studies have found positive and negative associations between one or more cardiovascular risk factors and brain-derived neurotrophic factor (BDNF) probably due to diverse methodological approaches when analysing peripheral BDNF levels. Moreover, only a few studies have been performed in youth populations. Consequently, the main objective of this study was to examine the association between serum BDNF and a composite z-score consisting of six cardiovascular risk factors. A secondary aim was to examine the associations between serum BDNF and each of the six risk factors. Methods Four hundred and forty-seven apparently healthy adolescents between 11–17 years of age participated in this cross-sectional study. Cardiorespiratory fitness (CRF), anthropometrics, pubertal status, blood pressure (BP), serum BDNF, high-density lipoprotein cholesterol (HDL-C), triglyceride (TG), blood glucose and insulin were measured. Information about alcohol consumption and socio-economic status was collected via questionnaires. Associations were modelled using linear regression analysis. Results Serum BDNF was positively associated with the composite z-score in the total study sample (standardized beta coefficient (std.β) = 0.10, P = 0.037). In males, serum BDNF was positively associated with the composite z-score (Std. β = 0.14, P = 0.034) and HOMA-IR (Std. β = 0.19, P = 0.004), and negatively associated with CRF (Std. β = -0.15, P = 0.026). In females, BDNF was positively associated with TG (Std. β = 0.14, P = 0.030) and negatively associated with waist circumference (WC) (Std. β = -0.16, P = 0.012). Conclusion Serum BDNF was positively associated with a composite z-score of cardiovascular risk factors. This association seems to be mainly driven by the association between TG, HOMA-IR and serum BDNF, and particularly for males. Further longitudinal research is warranted to determine the temporal relationship between BDNF and cardiovascular risk factors. PMID:29028824

HIV Services Provided by STD Programs in State and Local Health Departments - United States, 2013-2014.

The incidence of human immunodeficiency virus (HIV) infection in the United States is higher among persons with other sexually transmitted diseases (STDs), and the incidence of other STDs is increased among persons with HIV infection (1). Because infection with an STD increases the risk for HIV acquisition and transmission (1-4), successfully treating STDs might help reduce the spread of HIV among persons at high risk (1-4). Because health department STD programs provide services to populations who are at risk for HIV, ensuring service integration and coordination could potentially reduce the incidence of STDs and HIV. Program integration refers to the combining of STD and HIV prevention programs through structural, service, or policy-related changes such as combining funding streams, performing STD and HIV case matching, or integrating staff members (5). Some STD programs in U.S. health departments are partially or fully integrated with an HIV program (STD/HIV program), whereas other STD programs are completely separate. To assess the extent of provision of HIV services by state and local health department STD programs, CDC analyzed data from a sample of 311 local health departments and 56 state and directly funded city health departments derived from a national survey of STD programs. CDC found variation in the provision of HIV services by STD programs at the state and local levels. Overall, 73.1% of state health departments and 16.1% of local health departments matched STD case report data with HIV data to analyze possible syndemics (co-occurring epidemics that exacerbate the negative health effects of any of the diseases) and overlaps. Similarly, 94.1% of state health departments and 46.7% of local health departments performed site visits to HIV care providers to provide STD information or public health updates. One fourth of state health departments and 39.4% of local health departments provided HIV testing in nonclinical settings (field testing) for STD contacts, and all of these programs linked HIV cases to care. STD programs are providing some HIV services; however, delivery of certain specific services could be improved.

2010-08-01

This study investigates socio-demographic, behavioral, psychological, and structural factors associated with self-reported HIV/STD testing and willingness to test among 1,938 Chinese migrants. Overall, 6% and 14% of participants had ever been tested for HIV and STD, respectively. The results of multivariate analyses indicate that working at entertainment sectors, engaging in commercial sex, and utilization of health care were positively associated with both HIV and STD testing. Younger age, selling blood, perceived peer sexual risk involvement, and satisfaction with life were associated with HIV testing only. Female gender, early sexual debut, multiple sexual partners, and perceived vulnerability to HIV/STD were associated with STD testing only. Male gender, having premarital sex, perceived higher severity of and vulnerability to HIV/STD, and utilization of health care were associated with willingness to be tested for both HIV and STD. Interventions designed to raise the perception of vulnerability to HIV/STD and to improve access to and utilization of health care may be effective in encouraging more HIV testing in this vulnerable population.

Current approach to STD management in women.

PubMed

Amaral, E

1998-12-01

HIV infection was recognized as a new sexually transmitted disease (STD) at the beginning of the last decade. The knowledge of risk factors for sexual transmission of HIV changed the focus on STD to a broader perspective for prevention and control of HIV infection, and consequently of STD. Barriers to STD control include cultural aspects, difficulties in changing sexual behavior, asymptomatic disease in women and expensive and inaccessible tests for diagnosis. The classical clinical approach based on etiologic treatment has never been achieved by developing countries. The international community has been searching for new approaches. Syndromic management and mass treatment are strategies recently found as useful. Nevertheless the best approach to endocervicitis by Neisseria gonorrhoeae and Chlamydia trachomatis remain problematic. Then, the current approach to STD management must include: prompt attention to every patient seeking care for STD; early diagnosis and treatment; delivery of short term treatment at the clinic; education on STD/HIV; screening for other STDs with pre- and post-test counseling; counseling on risk reduction; provision of condoms; integration of STD services with family planning, prenatal and gynecological services.

Adolescent offenders may be at high risk for sexually transmitted diseases (STDs). With previous research and interventions focused on incarcerated adolescents, data are needed on STD prevalence and risk factors among newly arrested youth released to the community, a far larger subgroup. Participants were recruited from all arrested youth processed at the Hillsborough County, Florida Juvenile Assessment Center during the last half of 2006 (506 males, 442 females). Participants voluntarily providing urine samples for drug testing as part of standard protocol were also consented to having their specimens split and tested for chlamydia and gonorrhea, using an FDA-approved nucleic acid amplification test. STD prevalence was similar to those previously reported among incarcerated adolescents: 11.5% tested positive for chlamydia, 4.2% for gonorrhea, and 13.2% for either or both infections. Prevalence was significantly higher among females: 19.2% of females had either or both infections compared with 10.5% of males. Prevalence was higher for 17 to 18 year olds (15.2% of males, 25.5% of females), blacks, detained youths, drug users, and those engaged in sexual risk behaviors. Previous STD testing experience was limited. The study indicated that a voluntary STD screening protocol is feasible for arrested youth entering the juvenile justice system, and these offenders are at high risk for STDs. Because most arrested youths are released back to the community, routine testing and treatment of recently arrested youths, and expanded access to risk reduction and prevention programs, can yield substantial public health benefits.

Expanding HIV testing is important among individuals at increased risk for sexual HIV transmission in China, but little is known about prior HIV testing experiences among sexually transmitted disease (STD) patients. This cross-sectional study of 1792 outpatients from 6 public STD clinics in Guangdong Province recorded detailed information about ever having been tested for HIV infection in addition to sociodemographic variables, health seeking, clinical STD history, and HIV stigma using a validated survey instrument. A total of 456 (25.4%) of the STD patients in this sample had ever been tested for HIV infection. STD patients who were male, had higher income, more education, were at City A and City C, received STD services at public facilities, had used intravenous drugs, and had a history of an STD were more likely to ever receive an HIV test in multivariate analysis. Low perceived HIV risk was the most common reason for not receiving an HIV test. Only 7.7% of the sample reported fear of discrimination or loss of face as influencing their lack of HIV testing. Incomplete prior HIV screening among STD patients in China suggests the need for broadening HIV testing opportunities at STD clinics and similar clinical settings attended by those with increased sexual risk.

To evaluate postural control using a dynamic virtual reality environment and the relationship between postural metrics and history of falls in patients with glaucoma. Cross-sectional study. The study involved 42 patients with glaucoma with repeatable visual field defects on standard automated perimetry (SAP) and 38 control healthy subjects. Patients underwent evaluation of postural stability by a force platform during presentation of static and dynamic visual stimuli on stereoscopic head-mounted goggles. The dynamic visual stimuli presented rotational and translational ecologically valid peripheral background perturbations. Postural stability was also tested in a completely dark field to assess somatosensory and vestibular contributions to postural control. History of falls was evaluated by a standard questionnaire. Torque moments around the center of foot pressure on the force platform were measured, and the standard deviations of the torque moments (STD) were calculated as a measurement of postural stability and reported in Newton meters (Nm). The association with history of falls was investigated using Poisson regression models. Age, gender, body mass index, severity of visual field defect, best-corrected visual acuity, and STD on dark field condition were included as confounding factors. Patients with glaucoma had larger overall STD than controls during both translational (5.12 ± 2.39 Nm vs. 3.85 ± 1.82 Nm, respectively; P = 0.005) and rotational stimuli (5.60 ± 3.82 Nm vs. 3.93 ± 2.07 Nm, respectively; P = 0.022). Postural metrics obtained during dynamic visual stimuli performed better in explaining history of falls compared with those obtained in static and dark field condition. In the multivariable model, STD values in the mediolateral direction during translational stimulus were significantly associated with a history of falls in patients with glaucoma (incidence rate ratio, 1.85; 95% confidence interval, 1.30-2.63; P = 0.001). The study presented and validated a novel paradigm for evaluation of balance control in patients with glaucoma on the basis of the assessment of postural reactivity to dynamic visual stimuli using a virtual reality environment. The newly developed metrics were associated with a history of falls and may help to provide a better understanding of balance control in patients with glaucoma.

Participants The study involved 42 glaucoma patients with repeatable visual field defects on standard automated perimetry (SAP) and 38 control healthy subjects. Methods Patients underwent evaluation of postural stability by a force platform during presentation of static and dynamic visual stimuli on stereoscopic head-mounted goggles. The dynamic visual stimuli presented rotational and translational ecologically valid peripheral background perturbations. Postural stability was also tested in a completely dark field to assess somatosensory and vestibular contributions to postural control. History of falls was evaluated by a standard questionnaire. Main Outcome Measures Torque moments around the center of foot pressure on the force platform were measured and the standard deviations (STD) of these torque moments were calculated as a measurement of postural stability and reported in Newton meter (Nm). The association with history of falls was investigated using Poisson regression models. Age, gender, body mass index, severity of visual field defect, best-corrected visual acuity, and STD on dark field condition were included as confounding factors. Results Glaucoma patients had larger overall STD than controls during both translational (5.12 ± 2.39 Nm vs. 3.85 ± 1.82 Nm, respectively; P = 0.005) as well as rotational stimuli (5.60 ± 3.82 Nm vs. 3.93 ± 2.07 Nm, respectively; P = 0.022). Postural metrics obtained during dynamic visual stimuli performed better in explaining history of falls compared to those obtained in static and dark field condition. In the multivariable model, STD values in the mediolateral direction during translational stimulus were significantly associated with history of falls in glaucoma patients (incidence-rate ratio = 1.85; 95% CI: 1.30 – 2.63; P = 0.001). Conclusions The study presented and validated a novel paradigm for evaluation of balance control in glaucoma patients based on the assessment of postural reactivity to dynamic visual stimuli using a virtual reality environment. The newly developed metrics were associated with history of falls and may help to provide a better understanding of balance control in glaucoma patients. PMID:25892017

Decontaminating the DOE-STD-3013 Inner Container to Meet 10-CFR-835 Appendix D Requirements

DOE Office of Scientific and Technical Information (OSTI.GOV)

Martinez, H.E.; Nelson, T.O.; Rivera, Y.M.

The United States Department of Energy (DOE) has published a standard that specifies the criteria for preparation and packaging of plutonium metals and oxides for safe long-term storage (DOE-STD-3013-96). This standard is followed for the packaging of materials resulting from the disassembly of nuclear weapons at Los Alamos National Laboratory under the Advanced Retirement and Integrated Extraction System (ARIES) project. Declassified plutonium metal or oxide material from the ARES project is packaged into doubly contained and welded type 304L stainless steel containers that comply with the DOE standard. The 3013-96 standard describes requirements for maximum contamination limits on the outermore » surface of the sealed inner container. These limits are 500 dpm per 100 cm2 for direct measurements and 20 dpm per 100 cm2 for removable contamination. For containers filled, welded, and handled inside a highly contaminated glovebox line, these limits are difficult to obtain. Simple handling within the line is demonstrated to contaminate surfaces from 10,000 to 10,000,000 dpm alpha per 100 cm2. To routinely achieve contamination levels below the maximum contamination levels specified by the 3013-96 standard within a processing operation, a decontamination step must be included. In the ARIES line, this decontamination step is an electrolytic process that produces a controlled uniform etch of the container surfaces. Decontamination of the 3013-96 compliant ARIES inner container is well demonstrated. Within 30 to 50 minutes electrolysis time, tixed contamination is reduced to hundreds of dpm generally occurring only at electrode contact points and welds. Removable contamination is routinely brought to non-detectable levels. The total process time for the cycle (includes electrolysis, rinse, and dry stages) is on the order of 1.5 to 2 hours per container. The ARIES inner container decontamination system highly automated and consists of a plumbing loop, electronic controls and process monitors, and a decontamination chamber or "fixture". The tixture is situated like an air lock between a contaminated and an uncontaminated section of a processing glovebox. The welded and leak tested container is placed into the fixture through a door on the contaminated side and the electrolysis process is run, including rinse and dry cycles. The container is then removed through a second door into the uncontaminated side where it is monitored for surface alpha contamination, leak checked, and reweighed.« less

High performance 1553

NASA Astrophysics Data System (ADS)

Hegarty, Michael G.

2005-05-01

The U.S. Air Force is currently in the process of developing a revision to MIL-STD-1553 that will provide additional digital communication bandwidth beyond MIL-STD-1553B's 1 Megabit per second (Mbps) rate. The proposed revision to MIL-STD-1553 (referred to as MIL-STD-1553C) is targeting 200 Mbps as a baseline data rate. This paper explores the feasibility of the U.S. Air Force's proposed revision to MIL-STD-1553 based on studies conducted by Data Device Corporation (DDC). A combination of empirical and theoretical methods is used to determine if a MIL-STD-1553B network contains sufficient capacity to support the proposed 200 Mbps data rate. The results of DDC's analysis is that for some MIL-STD-1553 buses there is sufficient bandwidth to implement a broadband system in which legacy 1 Mbps 1553B waveforms could coexist with new 200 Mbps waveforms, thus providing an incremental high speed communication channel to existing MIL-STD-1553 buses.

How can we improve online HIV and STD prevention for men who have sex with men? Perspectives of hook-up website owners, website users, and HIV/STD directors.

Internet-based interventions have potential to reduce HIV and STD transmission among men who meet male sexual partners online. From November 2009 to May 2010 we surveyed dating and hook-up website users (n = 3,050), website owners (n = 18), and health department HIV/STD directors (n = 81) to identify structural and behavioral prevention interventions that could be implemented online and which a majority of website users were willing to use, owners were willing to implement, and HIV/STD directors perceived to be effective. A majority of each of the three stakeholder groups agreed on the following: (1) automated HIV/STD testing reminders, (2) local STD test site directories, (3) links to sex-positive safe sex videos, (4) access to sexual health experts, (5) profile options to include safer sex preference, (6) chat rooms for specific sexual interests, (7) filtering partners by their profile information, and (8) anonymous e-card partner notification for STD exposure. Findings help build consensus about how to prioritize resources for implementing online HIV and STD prevention interventions and highlight differences between stakeholders to guide future discussion about how to advance prevention efforts.

Condom use relative to knowledge of sexually transmitted disease prevention, method of birth control, and past or present infection.

PubMed

Fleisher, J M; Senie, R T; Minkoff, H; Jaccard, J

1994-12-01

The purpose of this study was to assess knowledge regarding STD spread and prevention, and to assess motivational and behavioral factors that influence the use of condoms to prevent STD acquisition among inner-city women at high risk for STD infection. In addition, the effect of past and/or current STD infection on a woman's knowledge of the mechanism of STD acquisition and subsequent use of a condom to prevent STD infection was explored. We utilized three inner-city clinics offering family planning or gynecologic care located in Brooklyn, New York. Our study linked clinical findings regarding current infection with chlamydia or Trichomonas vaginalis. One thousand four hundred and four sexually active black and Hispanic women participated in the study. A past history of STD (37%) or current infection (29%) was recorded for 54% of the study population (12% were positive for both past and current infection). On average, only 60% of women who reported prior treatment for STD infection reported receiving any information regarding prevention of re-infection during the course of treatment. Depending on the specific STD, from 6.8% to 42.9% of women reporting prior treatment for an STD did not know the disease they were being treated for was sexually transmitted. Condom use for disease prevention was more frequently reported by women who had previously been treated for an STD (OR = 1.62, 95% CI 1.23-2.13). However, condom use for contraception was a stronger predictor of use for STD prevention. Women who relied on condoms for contraception were almost 10 times more likely to also report condom use for STD prevention relative to women who did not use condoms for contraceptive purposes (OR = 9.71, 95% CI 7.0-13.5). In addition, condom use was associated with the perceived attitude of their sexual partner toward such use. Condom use to prevent STD acquisition was more than twice as frequently reported when a favorable attitude was perceived by a male sexual partner (OR = 2.30, 95% CI 1.54-3.43). Our findings suggest that prevention of unplanned pregnancy was a stronger motivator for condom use than disease prevention among the women comprising our study group. The findings also indicate the need for more extensive information regarding STD prevention among women at high risk for STD acquisition.(ABSTRACT TRUNCATED AT 400 WORDS)

Background Expanding HIV testing is important among individuals at increased risk for sexual HIV transmission in China, but little is known about prior HIV testing experiences among sexually transmitted disease (STD) patients. Methods This cross-sectional study of 1792 outpatients from six public sexually transmitted disease (STD) clinics in Guangdong Province recorded detailed information about ever having been tested for HIV infection in addition to socio-demographic variables, health seeking, clinical STD history, and HIV stigma using a validated survey instrument. Results 456 (25.4%) of the STD patients in this sample had ever been tested for HIV infection. STD patients who were male, had higher income, more education, were at City A and City C, received STD services at public facilities, had used intravenous drugs, and had a history of an STD were more likely to ever receive an HIV test in multivariate analysis. Low perceived HIV risk was the most common reason for not receiving an HIV test. Only 7.7% of the sample reported fear of discrimination or loss of face as influencing their lack of HIV testing. Conclusion Incomplete prior HIV screening among STD patients in China suggests the need for broadening HIV testing opportunities at STD clinics and similar clinical settings attended by those with increased sexual risk.

STD coinfections in The Netherlands: Specific sexual networks at highest risk.

PubMed

van Veen, Maaike G; Koedijk, Femke D H; van der Sande, Marianne A B

2010-07-01

Specific subpopulations infected with multiple bacterial sexually transmitted diseases (STDs) may facilitate ongoing STD transmission. To identify these subpopulations we determined the extent of concurrent incident STD infections and their risk factors among the high-risk population seen at Dutch STD clinics. STD surveillance data submitted routinely by STD clinics to the National Institute for Public Health on demographics, sexual behavior, STD testing, and diagnoses for the period 2004-2007 were analyzed. Bacterial STD coinfections were diagnosed concurrently in 2120 (7%) of the 31,754 incident bacterial STD diagnoses (chlamydia, gonorrhea, infectious syphilis). In univariate logistic regression analyses, coinfections were significantly more often diagnosed in men who have sex with men (MSM, OR = 5.4) than in heterosexuals. Multivariate analyses showed a significant interaction between age and sexual preference. Subsequent stratified analyses by sexual preference showed a linear rise in coinfections with age in MSM. In heterosexuals, by contrast, bacterial coinfections peaked in those aged 19 or less; they had 27% of coinfections, while having only 14% of monodiagnoses and 10% of consultations. Heterosexual STD clinic attendees of Surinamese or Antillean origin were significantly at higher risk for coinfection (OR = 6.5) than all other ethnicities. Attendees belonging to specific sexual networks, such as MSM, ethnic groups, and young heterosexuals were at increased risk for STD coinfections. The different trend with age in MSM versus heterosexuals suggests that these 2 high-risk networks have different determinants of higher risk, such as age-related sexual risk-taking, biologic susceptibility, and insufficient knowledge or compliance with prevention measures. Prevention should therefore be targeted differently towards specific sexual networks.

Sexually transmitted diseases (STDs) are increasing alarmingly with time among the young-adults in Bangladesh. The objective of the study was to investigate Sexual lifestyle, Risk Factors and Socioeconomic Status of the STD Patients. A total of 205 STD patients were selected following convenient method of sampling consistent with defined selection criteria from outpatient department of Skin and Venereal Disease of Mymensingh Medical College Hospital, Mymensingh. Period of data collection was from July 2014 to June 2015. The research instrument was an interviewer questionnaire and laboratory investigation reports. Results showed that the mean age of the respondents was 27±5.9 years of which 104(50.7%) unmarried and 95(46.3%) married. Level of education, 168(82.0%) of the STD patients were literate. Occupation of the STD patients, 201(98.0%) had specific occupation of which 74(36.1%) were businessmen, 48(23.4%) student, 24(11.7%) technical jobs, 20(9.8%) day labourer, 15(7.3%) household workers, 14(6.8%) service holders and 6(2.9%) were transport workers. Their average monthly income was Tk. 7892±6763. Majority of the STD patients 115((56.1%) expressed that they enjoyed extra-marital sex or illegal sex out of curiosity, 32(15.6%) habitual, 24(11.7%) to test sexual performance, 18(8.8%) inadequate response of the legal sex partners, 8(3.9%) hyper-sexuality and 8(3.9%) family disharmony. Most of the patients 200(97.6%) were heterosexual of which 165(80.5%) visited 1-10 sex partners, 18(8.8%) 11-20 sex partners and 22(10.7%) visited 21-100 sex partners in lifetime. In category of sex partners, 60(29.3%) were hotel-based sex partners, 111(54.1%) brothel-based, 20(9.8%) friends sex partners, 10(4.9%) street sex sellers and 4(2.0%) were residential sex partners respectively. Of them, 132(64.4%) did not use condom during sex, 65(31.7%) use it occasionally and only 8(3.9%) use condom regularly. Most of them 170((82.8%) had been suffering from gonococcal urethritis, 19(9.3%) non-gonococcal urethritis, 12(5.9%) genital herpes, and rest other specific infections. STDs were significantly (p<0.05) associated with category of sex partners and use of condom. Altering sexual lifestyle is still the only applicable way to stop this human catastrophe.

High fat diet and GLP-1 drugs induce pancreatic injury in mice

DOE Office of Scientific and Technical Information (OSTI.GOV)

Rouse, Rodney, E-mail: rodney.rouse@fda.hhs.gov; Xu, Lin; Stewart, Sharron

Glucagon Like Peptide-1 (GLP-1) drugs are currently used to treat type-2 diabetes. Safety concerns for increased risk of pancreatitis and pancreatic ductal metaplasia have accompanied these drugs. High fat diet (HFD) is a type-2 diabetes risk factor that may affect the response to GLP-1 drug treatment. The objective of the present study was to investigate the effects of diet and GLP-1 based drugs on the exocrine pancreas in mice. Experiments were designed in a mouse model of insulin resistance created by feeding a HFD or standard diet (STD) for 6 weeks. The GLP-1 drugs, sitagliptin (SIT) and exenatide (EXE) weremore » administered once daily for additional 6 weeks in both mice fed HFD or STD. The results showed that body weight, blood glucose levels, and serum levels of pro-inflammatory cytokines (TNFα, IL-1β, and KC) were significantly greater in HFD mice than in STD mice regardless of GLP-1 drug treatment. The semi-quantitative grading showed that pancreatic changes were significantly greater in EXE and SIT-treated mice compared to control and that HFD exacerbated spontaneous exocrine pancreatic changes seen in saline-treated mice on a standard diet. Exocrine pancreatic changes identified in this study included acinar cell injury (hypertrophy, autophagy, apoptosis, necrosis, and atrophy), vascular injury, interstitial edema and inflammation, fat necrosis, and duct changes. These findings support HFD as a risk factor to increased susceptibility/severity for acute pancreatitis and indicate that GLP-1 drugs cause pancreatic injury that can be exacerbated in a HFD environment.« less

Assessing the role of prevention partnerships in STD prevention: a review of comprehensive STD prevention systems progress reports.

PubMed

Hogben, Matthew; Hood, Julia; Collins, Dayne; McFarlane, Mary

2013-11-01

Systematic analysis of STD programme data contributes to a national portrait of sexually transmitted disease (STD) prevention activities, including research and evaluation specifically designed to optimise programme efficiency and impact. We analysed the narrative of the 2009 annual progress reports of the US Comprehensive STD Prevention Systems cooperative agreement for 58 STD programmes, concentrating on programme characteristics and partnerships. Programmes described 516 unique partnerships with a median of seven organisations cited per STD programme. Non-profit organisations (including service providers) were most frequently cited. Higher gonorrhoea morbidity was associated with reporting more partnerships; budget problems were associated with reporting fewer. Challenges to engaging in partnerships included budget constraints, staff turnover and low interest. Data provide a source of information for judging progress in programme collaboration and for informing a sustained programme-focused research and evaluation agenda.

Determinants of STD epidemics: implications for phase appropriate intervention strategies.

PubMed

Aral, S O

2002-04-01

Determinants of evolving epidemics of sexually transmitted diseases (STD) are equally influenced by the evolution of the STD epidemics themselves and by the evolution of human societies. A temporal approach to STD transmission dynamics suggests the need to monitor infectivity, rate of exposure between infected and susceptible individuals, and duration of infectiousness in societies. Different indicators may be used to monitor rate of exposure in the general population and in core groups. In addition, underlying determinants of STD epidemics such as poverty, inequality, racial/ethnic discrimination, unemployment, sex ratio, volume of migration, and health care coverage and quality are important variables to monitor through a surveillance system focused on social context. Ongoing large scale societal changes including urbanisation, globalisation, increasing inequality, and increasing volume of migrant populations may affect the evolution of STD epidemics. Globalised STD epidemics could pose a major challenge to local public health systems.

Saturation transfer difference (STD) is a valuable tool for studying the binding of small molecules to large biomolecules and for obtaining detailed information on the binding epitopes. Here, we demonstrate that the proposed (15)N/(13)C variants of group-selective, "GS-STD" experiments provide a powerful approach to mapping the binding epitope of a ligand even in the absence of efficient spin diffusion within the target protein. Therefore, these experimental variants broaden the scope of STD studies to smaller and/or more-dynamic targets. The STD spectra obtained in four different experimental setups (selective (1)H STD, (15)N GS-STD, (13)C(Ar) and (13)C(aliphatic) GS-STD approaches) revealed that the signal-intensity pattern of the difference spectra is affected by both the type and the spatial distribution of the excited "transmitter" atoms, as well as by the efficiency of the spin-diffusion-mediated magnetization transfer. The performance of the experiments is demonstrated on a system by using the lectin, galectin-1 and its carbohydrate ligand, lactose.

We evaluated whether routine biannual sexually transmitted disease (STD) testing coupled with brief risk-reduction counseling reduces STD incidence and high-risk behaviors. The SUN study is a prospective observational HIV cohort study conducted in 4 US cities. At enrollment and every 6 months thereafter, participants completed a behavioral survey and were screened for STDs, and if diagnosed, were treated. Medical providers conducted brief risk-reduction counseling with all patients. Among men who have sex with men (MSM), we examined trends in STD incidence and rates of self-reported risk behaviors before and after exposure to the risk-reduction intervention. The "preintervention" visit was the study visit that was at least 6 months after enrollment STD screening and treatment and at which the participant was first exposed to the intervention. The "postintervention" visit was 12 months later. Among 216 MSM with complete STD and behavioral data, median age was 44.5 years; 77% were non-Hispanic white; 83% were on highly active antiretroviral treatment; 84% had an HIV RNA level <400 copies/mL and the median CD4 (cluster of differentiation 4) count was 511 cells/mm. Twelve months after first exposure to the risk-reduction intervention, STD incidence declined from 8.8% to 4.2% (P = 0.041). Rates of unprotected receptive or insertive anal intercourse with HIV-positive partners increased (19% to 25%, P = 0.024), but did not change with HIV-negative partners or partners of unknown HIV status (24% to 22%, P = 0.590). STD incidence declined significantly among HIV-infected MSM after implementing frequent, routine STD testing coupled with risk-reduction counseling. These findings support adoption of routine STD screening and risk-reduction counseling for HIV-infected MSM.

Investigation of the binding of a carbohydrate-mimetic peptide to its complementary anticarbohydrate antibody by STD-NMR spectroscopy and molecular-dynamics simulations.

Saturation transfer difference (STD)-NMR spectroscopy was used to probe experimentally the bioactive solution conformation of the carbohydrate mimic MDWNMHAA 1 of the O-polysaccharide of Shigella flexneri Y when bound to its complementary antibody, mAb SYA/J6. Molecular dynamics simulations using the ZymeCAD™ Molecular Dynamics platform were also undertaken to give a more accurate picture of the conformational flexibility and the possibilities for bound ligand conformations. The ligand topology, or the dynamic epitope, was mapped with the CORCEMA-ST (COmplete Relaxation and Conformational Exchange Matrix Analysis of Saturation Transfer) program that calculates a total matrix analysis of relaxation and exchange effects to generate predicted STD-NMR intensities from simulation. The comparison of these predicted STD enhancements with experimental data was used to select a representative binding mode. A protocol that employed theoretical STD effects calculated at snapshots during the entire course of a molecular dynamics (MD) trajectory of the peptide bound to the Fv portion of the antibody, and not the averaged atomic positions of receptor-ligand complexes, was also examined. In addition, the R factor was calculated on the basis of STD (fit) to avoid T1 bias, and an effective R factor, R(eff), was defined such that if the calculated STD (fit) for proton k was within error of the experimental STD (fit) for proton k, then that calculated STD (fit) for proton k was not included in the calculation of the R factor. This protocol was effective in deriving the antibody-bound solution conformation of the peptide which also differed from the bound conformation determined by X-ray crystallography; however, several discrepancies between experimental and calculated STD (fit) values were observed. The bound conformation was therefore further refined with a simulated annealing refinement protocol known as STD-NMR intensity-restrained CORCEMA optimization (SICO) to give a more accurate representation of the bound peptide epitope. Further optimization was required in this case, but a satisfactory correlation between experimental and calculated STD values was obtained. Attempts were also made to obtain STD enhancements with a synthetic pentasaccharide hapten, corresponding to the O-polysaccharide, while bound to the antibody. However, unfavorable kinetics of binding in this system prevented sufficient STD build-up, which, in turn, hindered a rigorous analysis via full STD build-up curves.

The Effects of Turbulence on Tthe Measurements of Five-Hole Probes

NASA Astrophysics Data System (ADS)

Diebold, Jeffrey Michael

The primary goals of this research were to quantify the effects of turbulence on the measurements of five-hole pressure probes (5HP) and to develop a model capable of predicting the response of a 5HP to turbulence. The five-hole pressure probe is a commonly used device in experimental fluid dynamics and aerodynamics. By measuring the pressure at the five pressure ports located on the tip of the probe it is possible to determine the total pressure, static pressure and the three components of velocity at a point in the flow. Previous research has demonstrated that the measurements of simple pressure probes such as Pitot probes are significantly influenced by the presence of turbulence. Turbulent velocity fluctuations contaminate the measurement of pressure due to the nonlinear relationship between pressure and velocity as well as the angular response characteristics of the probe. Despite our understanding of the effects of turbulence on Pitot and static pressure probes, relatively little is known about the influence of turbulence on five-hole probes. This study attempts to fill this gap in our knowledge by using advanced experimental techniques to quantify these turbulence-induced errors and by developing a novel method of predicting the response of a five-hole probe to turbulence. A few studies have attempted to quantify turbulence-induced errors in five-hole probe measurements but they were limited by their inability to accurately measure the total and static pressure in the turbulent flow. The current research utilizes a fast-response five-hole probe (FR5HP) in order to accurately quantify the effects of turbulence on different standard five-hole probes (Std5HP). The FR5HP is capable of measuring the instantaneous flowfield and unlike the Std5HP the FR5HP measurements are not contaminated by the turbulent velocity fluctuations. Measurements with the FR5HP and two different Std5HPs were acquired in the highly turbulent wakes of 2D and 3D cylinders in order to quantify the turbulence-induced errors in Std5HP measurements. The primary contribution of this work is the development and validation of a simulation method to predict the measurements of a Std5HP in an arbitrary turbulent flow. This simulation utilizes a statistical approach to estimating the pressure at each port on the tip of the probe. The angular response of the probe is modeled using experimental calibration data for each five-hole probe. The simulation method is validated against the experimental measurements of the Std5HPs, and then used to study the how the characteristics of the turbulent flowfield influence the measurements of the Std5HPs. It is shown that total pressure measured by a Std5HP is increased by axial velocity fluctuations but decreased by the transverse fluctuations. The static pressure was shown to be very sensitive to the transverse fluctuations while the axial fluctuations had a negligible effect. As with Pitot probes, the turbulence-induced errors in the Std5HPs measurements were dependent on both the properties of the turbulent flow and the geometry of the probe tip. It is then demonstrated that this simulation method can be used to correct the measurements of a Std5HP in a turbulent flow if the characteristics of the turbulence are known. Finally, it is demonstrated that turbulence-induced errors in Std5HP measurements can have a substantial effect on the determination of the profile and vortex-induced drag from measurements in the wake of a 3D body. The results showed that while the calculation of both drag components was influenced by turbulence-induced errors the largest effect was on the determination of vortex-induced drag.

2012-01-01

Unprecedented growth of required telecommunications services and telecommunications applications change the way the INL does business today. High speed connectivity compiled with a high demand for telephony and network services requires a robust communications infrastructure.   The current state of the MFC communication infrastructure limits growth opportunities of current and future communication infrastructure services. This limitation is largely due to equipment capacity issues, aging cabling infrastructure (external/internal fiber and copper cable) and inadequate space for telecommunication equipment. While some communication infrastructure improvements have been implemented over time projects, it has been completed without a clear overall plan and technology standard.more »   This document identifies critical deficiencies with the current state of the communication infrastructure in operation at the MFC facilities and provides an analysis to identify needs and deficiencies to be addressed in order to achieve target architectural standards as defined in STD-170. The intent of STD-170 is to provide a robust, flexible, long-term solution to make communications capabilities align with the INL mission and fit the various programmatic growth and expansion needs.« less

Spectral velocity estimation is considered the gold standard in medical ultrasound. Peak systole (PS), end diastole (ED), and resistive index (RI) are used clinically. Angle correction is performed using a flow angle set manually. With Transverse Oscillation (TO) velocity estimates the flow angle, peak systole (PSTO), end diastole (EDTO), and resistive index (RITO) are estimated. This study investigates if these clinical parameters are estimated equally good using spectral and TO data. The right common carotid arteries of three healthy volunteers were scanned longitudinally. Average TO flow angles and std were calculated { 52+/-18 ; 55+/-23 ; 60+/-16 }°. Spectral angles { 52 ; 56 ; 52 }° were obtained from the B-mode images. Obtained values are: PSTO { 76+/-15 ; 89+/-28 ; 77+/-7 } cm/s, spectral PS { 77 ; 110 ; 76 } cm/s, EDTO { 10+/-3 ; 14+/-8 ; 15+/-3 } cm/s, spectral ED { 18 ; 13 ; 20 } cm/s, RITO { 0.87+/-0.05 ; 0.79+/-0.21 ; 0.79+/-0.06 }, and spectral RI { 0.77 ; 0.88 ; 0.73 }. Vector angles are within +/-two std of the spectral angle. TO velocity estimates are within +/-three std of the spectral estimates. RITO are within +/-two std of the spectral estimates. Preliminary data indicates that the TO and spectral velocity estimates are equally good. With TO there is no manual angle setting and no flow angle limitation. TO velocity estimation can also automatically handle situations where the angle varies over the cardiac cycle. More detailed temporal and spatial vector estimates with diagnostic potential are available with the TO velocity estimation.

Objectives To identify the prevalence of condom use errors among detained female teens and to test two inter-related hypotheses concerning condom failure. Methods A cross-sectional survey of 134 female teens recruited within eight detention facilities. Measures were collected using audio-computer assisted self-interviewing. Assessment for the presence of C. trachomatis and N. gonorrhoeae was also conducted. Results Five forms of condom use errors/problems were common: not discussing condom use with the partner (34.3%), not having a condom when one was desired (48.5%), starting sex before application (21.6%), removing condoms before sex concludes (26.9%), and breakage (32.8%). Significant, associations were found between condom errors/problems and drug/alcohol use. Errors/problems with condom use were significantly higher among teens diagnosed with an STD (P=.039 for an index measure; P=.022 for a single-item measure). Conclusions Findings suggest that detained female teens may have experienced multiple condom use error and problems thereby increasing their vulnerability to STD acquisition. PMID:18082855

Defining Medical Levels of Care for Exploration Missions

Hailey, M.; Reyes, D.; Urbina, M.; Rubin, D.; Antonsen, E.

2017-01-01

NASA medical care standards establish requirements for providing health and medical programs for crewmembers during all phases of a mission. These requirements are intended to prevent or mitigate negative health consequences of long-duration spaceflight, thereby optimizing crew health and performance over the course of the mission. Current standards are documented in the two volumes of the NASA-STD-3001 Space Flight Human-System Standard document, established by the Office of the Chief Health and Medical Officer. Its purpose is to provide uniform technical standards for the design, selection, and application of medical hardware, software, processes, procedures, practices, and methods for human-rated systems. NASA-STD-3001 Vol. 1 identifies five levels of care for human spaceflight. These levels of care are accompanied by several components that illustrate the type of medical care expected for each. The Exploration Medical Capability (ExMC) of the Human Research Program has expanded the context of these provided levels of care and components. This supplemental information includes definitions for each component of care and example actions that describe the type of capabilities that coincide with the definition. This interpretation is necessary in order to fully and systematically define the capabilities required for each level of care in order to define the medical requirements and plan for infrastructure needed for medical systems of future exploration missions, such as one to Mars.

Purpose: To establish a minimum number of patients required to obtain statistically accurate Planning Target Volume (PTV) margins for prostate Intensity Modulated Radiation Therapy (IMRT). Methods: A total of 320 prostate patients, consisting of a total number of 9311 daily setups, were analyzed. These patients had gone under IMRT treatments. Daily localization was done using the skin marks and the proper shifts were determined by the CBCT to match the prostate gland. The Van Herk formalism is used to obtain the margins using the systematic and random setup variations. The total patient population was divided into different grouping sizes varyingmore » from 1 group of 320 patients to 64 groups of 5 patients. Each grouping was used to determine the average PTV margin and its associated standard deviation. Results: Analyzing all 320 patients lead to an average Superior-Inferior margin of 1.15 cm. The grouping with 10 patients per group (32 groups) resulted to an average PTV margin between 0.6–1.7 cm with the mean value of 1.09 cm and a standard deviation (STD) of 0.30 cm. As the number of patients in groups increases the mean value of average margin between groups tends to converge to the true average PTV of 1.15 cm and STD decreases. For groups of 20, 64, and 160 patients a Superior-Inferior margin of 1.12, 1.14, and 1.16 cm with STD of 0.22, 0.11, and 0.01 cm were found, respectively. Similar tendency was observed for Left-Right and Anterior-Posterior margins. Conclusion: The estimation of the required margin for PTV strongly depends on the number of patients studied. According to this study at least ∼60 patients are needed to calculate a statistically acceptable PTV margin for a criterion of STD < 0.1 cm. Numbers greater than ∼60 patients do little to increase the accuracy of the PTV margin estimation.« less

The objective of this study was to determine if there were any demographic, behavioral, and clinical differences between clients seen aboard a mobile sexually transmitted disease (STD)/HIV clinic compared with those seen in a traditional municipal STD/HIV health clinic for receipt of STD/HIV services. Clients seen in the two different settings were interviewed about demographic characteristics, reasons for their visit, STD history, their HIV/STD risk factors, and the risk factors of their sex partners. Clients in both settings were also offered testing for syphilis, gonorrhea, chlamydia, and HIV. Results suggested that clients seen at the mobile clinic were older, more likely to be injecting drug users themselves and/or to have sex partners who were, or had engaged in prostitution for money or drugs. Over half (54.4%) of the mobile clinic clients sought testing for HIV, and they were far less likely to be seeking care for symptoms of an STD. In contrast, only 7.1% of municipal clinic clients indicated HIV testing as the reason for their visit, whereas nearly two thirds (64.5%) reported symptoms of disease. Two percent of municipal clinic clients and 5.4% of mobile clinic clients had a positive HIV test ( p<.001), and 17.8% of STD clinic clients and 5.6% of mobile van clients had a positive gonorrhea and/or test ( p<.001). These data suggest that a mobile STD/HIV clinic may be an effective strategy to reach individuals at high risk for HIV who are not being served by traditional municipal STD/HIV health clinics.

Alternative Test Methods for Electronic Parts

NASA Technical Reports Server (NTRS)

Plante, Jeannette

2004-01-01

It is common practice within NASA to test electronic parts at the manufacturing lot level to demonstrate, statistically, that parts from the lot tested will not fail in service using generic application conditions. The test methods and the generic application conditions used have been developed over the years through cooperation between NASA, DoD, and industry in order to establish a common set of standard practices. These common practices, found in MIL-STD-883, MIL-STD-750, military part specifications, EEE-INST-002, and other guidelines are preferred because they are considered to be effective and repeatable and their results are usually straightforward to interpret. These practices can sometimes be unavailable to some NASA projects due to special application conditions that must be addressed, such as schedule constraints, cost constraints, logistical constraints, or advances in the technology that make the historical standards an inappropriate choice for establishing part performance and reliability. Alternate methods have begun to emerge and to be used by NASA programs to test parts individually or as part of a system, especially when standard lot tests cannot be applied. Four alternate screening methods will be discussed in this paper: Highly accelerated life test (HALT), forward voltage drop tests for evaluating wire-bond integrity, burn-in options during or after highly accelerated stress test (HAST), and board-level qualification.

This study is to determine the prevalence of unintended pregnancy and its risk factors among the female attendees of sexually transmitted disease (STD) clinics in Zhejiang Province, China. A self-administered questionnaire survey of a cross-sectional design was administered to attendees at four STD clinics in 2007. Of the 313 female STD clinic attendees, 42.5% reported that they had at least one unintended pregnancy; the induced abortion rate was 39.0%. Over their lifetime, 12.1% responded “use condoms always/often” and 5.4% “always/often used oral contraceptives.” The risk factors for the unintended pregnancy identified by the multivariate analysis were as follows: being married, experience of nonconsensual sex, and a history of STD, having two and over two sexual partners. Unintended pregnancies and induced abortion by female STD clinic attendees have reached an alarming prevalence. Doctors at STD clinics should attach importance not only to the STD problem of the female attendees, but also to the unintended pregnancy and the associated factors. Targeted contraceptive counseling and intervention should be promoted at STD clinics as a strategy to improve the efficiency and effectiveness of the reproductive health services in China.

US surveillance of sexually transmitted diseases (STDs) is often delayed and incomplete which creates missed opportunities to identify and respond to trends in disease. Internet search engine data has the potential to be an efficient, economical and representative enhancement to the established surveillance system. Google Trends allows the download of de-identified search engine data, which has been used to demonstrate the positive and statistically significant association between STD-related search terms and STD rates. In this study, search engine user content was identified by surveying specific exposure groups of individuals (STD clinic patients and university students) aged 18-35. Participants were asked to list the terms they use to search for STD-related information. Google Correlate was used to validate search term content. On average STD clinic participant queries were longer compared to student queries. STD clinic participants were more likely to report using search terms that were related to symptomatology such as describing symptoms of STDs, while students were more likely to report searching for general information. These differences in search terms by subpopulation have implications for STD surveillance in populations at most risk for disease acquisition.

To describe the characteristics of monitoring stations for the infectious disease surveillance system in Japan, we compared the distributions of the number of monitoring stations in terms of population, region, size of medical institution, and medical specialty. The distributions of annual number of reported cases in terms of the type of diseases, the size of medical institution, and medical specialty were also compared. We conducted a nationwide survey of the pediatrics stations (16 diseases), ophthalmology stations (3 diseases) and the stations of sexually transmitted diseases (STD) (5 diseases) in Japan. In the survey, we collected the data of monitoring stations and the annual reported cases of diseases. We also collected the data on the population, served by the health center where the monitoring stations existed, from the census. First, we compared the difference between the present number of monitoring stations and the current standard established by the Ministry of Health and Welfare (MHW). Second, we compared the distribution of all medical institutions in Japan and the monitoring stations in terms of the size of the medical institution. Third, we compared the average number of annual reported cases of diseases in terms of the size of medical institution and the medical specialty. In most health centers, the number of monitoring stations achieved the current standard of MHW, while a few health centers had no monitoring station, although they had a large population. Most prefectures also achieved the current standard of MHW, but some prefectures were well below the standard. Among pediatric stations, the sampling proportion of large hospitals was higher than other categories. Among the ophthalmology stations, the sampling proportion of hospitals was higher than other categories. Among the STD stations, the sampling proportion of clinics of obstetrics and gynecology was lower than other categories. Except for some diseases, it made little difference in the average number of annual reported cases of diseases in terms of the type of medical institution. Among STD, there was a great difference in the average number of annual reported cases of diseases in terms of medical specialty.

The Patient Protection and Affordable Care Act is expected to reduce the number of uninsured people in the United States during the next eight years, but more than 10% are expected to remain uninsured. Uninsured people are one of the main populations using publicly funded safety net sexually transmitted disease (STD) prevention services. Estimating the proportion of the uninsured population expected to need STD services could help identify the potential demand for safety net STD services and improve program planning. In 2013, an estimated 8.27 million people met the criteria for being in need of STD services. In 2023, 4.70 million uninsured people are expected to meet the criteria for being in need of STD services. As an example, the cost in 2014 U.S. dollars of providing chlamydia screening to these people was an estimated $271.1 million in 2013 and is estimated to be $153.8 million in 2023. A substantial need will continue to exist for safety net STD prevention services in coming years.

Burn injury induces a hypercatabolic inflammatory state, predisposing burn patients to malnutrition, poor wound healing, and infectious complications. We conducted this study to determine what effect a diet fortified with fish oil and arginine (FAD) would have on wound healing in a thermally injured population. Twenty-three thermally injured patients were enrolled in this randomized double blind enteral feeding study from July 2002 to August 2004. All study patients received isonitrogenous enteral intragastric feeding within 48 hours of admission. Patients were randomized to our standard diet (STD, ProBalance with Promix, Probalance from Nestlé, Glendale, CA; ProMix R.D., Navaco Laboratories, Phoenix, AZ) or a diet fortified with fish oil and arginine (FAD, Crucial, Nestlé Nutrition Glendale, CA) Diets were advanced as tolerated to meet 100% of estimated needs. The primary endpoint of the study was time to heal the first donor site. There were no statistical differences between the study groups with respect to baseline characteristics. Both diets were well tolerated, and there were no differences in the daily total kilocalories or protein intake per kilogram between the two diet groups throughout the study. Although nonsignificant, the patients in the FAD group showed a slightly faster healing time than those in the STD group (10.8 +/- 2.7 days vs 12.3 +/- 5.2 days, respectively). This trend was further accelerated when those with body surface area burns less than 30% were examined (patients with body surface area burns <30% in the FAD healed in 9.0 +/- 1.7 vs corresponding patients in the standard group who healed in 12.2 +/- 6.2, P = .63). Patients in the FAD group trended to more infections and more adverse complications. The adverse complications were predominantly associated with inhalation injuries. The role of fortified enteral diets in the outcomes of thermally injured patients deserves further study. Such a future study should be conducted in a multicenter trial and involve inhalation injury stratification systems to accurately score and randomize patients for inhalation injury. Finally, the frequency and pattern of infections in patients receiving fortified enteral diets deserves further evaluation.

Interconnect or "bus" is one of the critical technologies in design of spacecraft avionics systems that dictates its architecture and complexity. MIL-STD-1553B has long been used as the avionics backbone technology. As avionics systems become more and more capable and complex, however, limitations of MIL-STD-1553B such as insufficient 1 Mbps bandwidth and separability have forced current avionics architects and designers to use combination of different interconnect technologies in order to meet various requirements: CompactPCI is used for backplane interconnect; LVDS or RS422 is used for low and high-speed direct point-to-point interconnect; and some proprietary interconnect standards are designed for custom interfaces. This results in a very complicated system that consumes significant spacecraft mass and power and requires extensive resources in design, integration and testing of spacecraft systems.

To improve endoscopic surgical skills, an increasing number of surgical residents practice on box or virtual reality (VR) trainers. Current training is focused mainly on hand-eye coordination. Training methods that focus on applying the right amount of force are not yet available. The aim of this project is to develop a low-cost training system that measures the interaction force between tissue and instruments and displays a visual representation of the applied forces inside the camera image. This visual representation continuously informs the subject about the magnitude and the direction of applied forces. To show the potential of the developed training system, a pilot study was conducted in which six novices performed a needle-driving task in a box trainer with visual feedback of the force, and six novices performed the same task without visual feedback of the force. All subjects performed the training task five times and were subsequently tested in a post-test without visual feedback. The subjects who received visual feedback during training exerted on average 1.3 N (STD 0.6 N) to drive the needle through the tissue during the post-test. This value was considerably higher for the group that received no feedback (2.6 N, STD 0.9 N). The maximum interaction force during the post-test was noticeably lower for the feedback group (4.1 N, STD 1.1 N) compared with that of the control group (8.0 N, STD 3.3 N). The force-sensing training system provides us with the unique possibility to objectively assess tissue-handling skills in a laboratory setting. The real-time visualization of applied forces during training may facilitate acquisition of tissue-handling skills in complex laparoscopic tasks and could stimulate proficiency gain curves of trainees. However, larger randomized trials that also include other tasks are necessary to determine whether training with visual feedback about forces reduces the interaction force during laparoscopic surgery.

The increase in human immunodeficiency virus (HIV) among men who have sex with men (MSM) in Israel during the last decade raises concerns regarding other sexuallytransmitted diseases (STD) in MSM, which are yet undetermined. To evaluate the STD burden among MSM and heterosexuals visiting the Tel Aviv walk-in STD clinic. Records of all male patients who attended the clinic once were reviewed to identify demographic characteristics, behavioral attributes, and test results. Between 2002 and 2008, 1064 MSM (22%) and 3755 heterosexuals (78%) visited the clinic once. Positivity rates in MSM for HIV, urethral Neisseria gonorrhoea and infectious syphilis were higher than in heterosexuals (2.5%, 2.5%. 0.7% vs. 0.6%, 1.3%, 0.3%, respectively), while urethral Chlamydia trachomatis was higher in heterosexuals than in MSM (2.7% and 1.4%, respectively). MSM tested in our clinic were younger than heterosexuals (P<0.001), more commonly circumcised (P=0.03) and Israeli-born (P<0.001), used substances during sex (P=0.04), and had prior STD (P<0.001), a greater number of sexual partners (P<0.001), and earlier sexual debut (P=0.02). The final multivariate results for MSM to be diagnosed with HIV/STD were greater number of sexual contacts, previous diagnosis with STD, and infrequent use of condom during anal intercourse. MSM visiting the Levinsky Clinic had higher rates of HIV/STD than heterosexual males, which correlated with their higher-risk behaviors. The unique characteristics of MSM found in our study, such as sex work, substance use, previous diagnosis of STD, multiple partners and inconsistent use of condom during anal sex should be addressed with innovative interventions to prevent STD/HIV in the gay community in Israel.

We examined the infrastructure for US public sexually transmitted disease (STD) clinical services. In 2013 to 2014, we surveyed 331 of 1225 local health departments (LHDs) who either reported providing STD testing/treatment in the 2010 National Profile of Local Health Departments survey or were the 50 local areas with the highest STD cases or rates. The sample was stratified by jurisdiction population size. We examined the primary referral clinics for STDs, the services offered and the impact of budget cuts (limited to government funding only). Data were analyzed using SAS, and analyses were weighted for nonresponse. Twenty-two percent of LHDs cited a specialty STD clinic as their primary referral for STD services; this increased to 53.5% of LHDs when combination STD-family planning clinics were included. The majority of LHDs (62.8%) referred to clinics providing same-day services. Sexually transmitted disease clinics more frequently offered extragenital testing for chlamydia and/or gonorrhea (74.7%) and gonorrhea culture (68.5%) than other clinics (52.9%, 46.2%, respectively; P < 0.05). The majority of LHDs (61.5%) reported recent budget cuts. Of those with decreased budgets, the most common impacts were fewer clinic hours (42.8%; 95% confidence interval [CI], 24.4-61.2), reduced routine screening (40.2%; 95% CI, 21.7-58.8) and reductions in partner services (42.1%; 95% CI, 23.6-60.7). One quarter of those with reduced STD budgets increased fees or copays for clients. Findings demonstrate gaps and reductions in US public STD services including clinical services that play an important role in reducing disease transmission. Furthermore, STD clinics tended to offer more specialized STD services than other public clinics.

In the United States, young people (ages 15-24 years) are disproportionately affected by human immunodeficiency virus (HIV) and other sexually transmitted diseases (STDs), due at least in part to inadequate or incorrect HIV/STD-related knowledge, attitudes, beliefs, and behavioral intentions (KABI). Comic book narratives are a proven method of HIV/STD prevention communication to strengthen KABI for HIV/STD prevention. Motion comics, a new type of comic media, are an engaging and low-cost means of narrative storytelling. The objective of this study was to quantitatively evaluate the effectiveness of a pilot six-episode HIV/STD-focused motion comic series to improve HIV/STD-related KABI among young people. We assessed change in HIV/STD knowledge, HIV stigma, condom attitudes, HIV/STD testing attitudes, and behavioral intentions among 138 participants in 15 focus groups immediately before and after viewing the motion comic series. We used paired t-tests and indicators of overall improvement to assess differences between surveys. We found a significant decrease in HIV stigma (p < .001) and increases in both HIV knowledge (p = .002) and behavioral intentions to engage in safe sex (p < .001). In summary, this motion comic intervention improved HIV/STD-related KABI of young adult viewers by reducing HIV stigma and increasing behavioral intentions to engage in safer sex. Our results demonstrate the promise of this novel intervention and support its use to deliver health messages to young people.

Possibilities of inversion of satellite third-order gravitational tensor onto gravity anomalies: a case study for central Europe

NASA Astrophysics Data System (ADS)

Pitoňák, Martin; Šprlák, Michal; Tenzer, Robert

2017-05-01

We investigate a numerical performance of four different schemes applied to a regional recovery of the gravity anomalies from the third-order gravitational tensor components (assumed to be observable in the future) synthetized at the satellite altitude of 200 km above the mean sphere. The first approach is based on applying a regional inversion without modelling the far-zone contribution or long-wavelength support. In the second approach we separate integral formulas into two parts, that is, the effects of the third-order disturbing tensor data within near and far zones. Whereas the far-zone contribution is evaluated by using existing global geopotential model (GGM) with spectral weights given by truncation error coefficients, the near-zone contribution is solved by applying a regional inversion. We then extend this approach for a smoothing procedure, in which we remove the gravitational contributions of the topographic-isostatic and atmospheric masses. Finally, we apply the remove-compute-restore (r-c-r) scheme in order to reduce the far-zone contribution by subtracting the reference (long-wavelength) gravity field, which is computed for maximum degree 80. We apply these four numerical schemes to a regional recovery of the gravity anomalies from individual components of the third-order gravitational tensor as well as from their combinations, while applying two different levels of a white noise. We validated our results with respect to gravity anomalies evaluated at the mean sphere from EGM2008 up to the degree 250. Not surprisingly, better fit in terms of standard deviation (STD) was attained using lower level of noise. The worst results were gained applying classical approach, STD values of our solution from Tzzz are 1.705 mGal (noise value with a standard deviation 0.01 × 10 - 15m - 1s - 2) and 2.005 mGal (noise value with a standard deviation 0.05 × 10 - 15m - 1s - 2), while the superior from r-c-r up to the degree 80, STD fit of gravity anomalies from Tzzz with respect to the same counterpart from EGM2008 is 0.510 mGal (noise value with a standard deviation 0.01 × 10 - 15m - 1s - 2) and 1.190 mGal (noise value with a standard deviation 0.05 × 10 - 15m - 1s - 2).

Few studies have examined whether and how receiving an sexually transmitted disease (STD) diagnosis while in a romantic relationship relates to condom use and psychosocial sexual outcomes. Using dyadic data, we examined associations of a personal or a partner’s STD diagnosis during a relationship with condom use, monogamy intentions, condom intentions and attitudes, and STD susceptibility and communication. Because beliefs about how the STD was acquired may shape associations with behavior and cognitions, gender and suspecting that one’s partner had other sexual partners (i.e., partner concurrency) were examined as moderators. Participants were 592 individuals in 296 couples expecting a baby; 108 individuals had been diagnosed with an STD during the relationship. Personal STD diagnosis was unrelated to outcomes or was associated with increased risk. A partner’s diagnosis related to more positive condom intentions and attitudes. Among men who suspected concurrency, both a personal and a partner’s STD diagnosis were associated with less condom use. Receiving the STD diagnosis during pregnancy was associated with greater susceptibility and marginally greater condom use. Results suggest potential benefits of enhancing communication and encouraging joint risk reduction counseling among couples, engaging men more fully in preventive efforts, and capitalizing on the short window during which risk reduction occurs.

High rates of psychosocial and health problems have been identified among patients attending sexually transmitted disease (STD) clinics, who are disproportionately urban, have low income, and are racial/ethnic minorities. This study sought to determine whether these problems co-occurred and whether they indicated the presence of a syndemic. Patients (N = 1557, 46% female, 64% African American) attending an urban STD clinic completed a computerized survey assessing childhood sexual abuse (CSA), depressive symptoms, binge drinking, marijuana use, intimate partner violence (IPV), and sexual risk behavior. Medical records were reviewed to determine incident STD diagnosis. The psychosocial and health problems were interrelated. Endorsing more psychosocial problems was associated with a greater likelihood of having multiple sexual partners and STD diagnosis. Interactions between CSA and marijuana use and between CSA and IPV predicted STD diagnosis. Numerous psychosocial and health problems co-occur among urban STD clinic patients. There was some evidence of a syngergistic relationship (i.e., a syndemic) between these conditions, resulting in worsened sexual health outcomes. Health care needs to be multidisciplinary to address the multiple psychosocial and health problems faced by STD clinic patients. Research needs to identify factors that may underlie these comorbid conditions.

To investigate the feasibility of grayscale quantitative diagnostic method for biceps tendinitis and determine the cut-off points of a quantitative biceps ultrasound (US) method to diagnose biceps tendinitis. Design. Prospective cross-sectional case controlled study. Outpatient rehabilitation service. A total of 336 shoulder pain patients with suspected biceps tendinitis were recruited in this prospective observational study. The grayscale pixel data of the range of interest (ROI) were obtained for both the transverse and longitudinal views of the biceps US. A total of 136 patients were classified with biceps tendinitis, and 200 patients were classified as not having biceps tendinitis based on the diagnostic criteria. Based on the Youden index, the cut-off points were determined as 26.85 for the transverse view and 21.25 for the longitudinal view of the standard deviation (StdDev) of the ROI values, respectively. When the ROI evaluation of the US surpassed the cut-off point, the sensitivity was 68% and the specificity was 90% in the StdDev of the transverse view, and the sensitivity was 81% and the specificity was 73% in the StdDev of the longitudinal view to diagnose biceps tendinitis. For equivocal cases or inexperienced sonographers, our study provides a more objective method for diagnosing biceps tendinitis in shoulder pain patients.

Obesity is associated with increased pancreatic cancer risk, although the mechanisms have yet to be detailed. This study aimed to elucidate promotion of pancreatic cancer by obesity and hyperlipidemia. Six-week-old female Syrian golden hamsters were treated with N-nitrosobis(2-oxopropyl)amine (BOP) and after 1 week were fed a high-fat diet (HFD) or standard diet (STD) for 6 or 17 weeks. Body weight and serum levels of lipids and leptin were significantly higher in the HFD than the STD group at 14 weeks of age. Pancreatic ductal adenocarcinomas developed only in the BOP + HFD group, with an incidence of 67% (P < 0.01) at 14 weeks of age. In addition, the multiplicity was 2-fold greater in the BOP + HFD group than in the BOP + STD group (P < 0.05) at 25 weeks of age. Pancreatic fatty infiltration was increased by BOP treatment and further enhanced by the HFD, correlating with progression of BOP-induced pancreatic ductal adenocarcinoma and up-regulated expression of adipocytokines and cell proliferation-related genes in the pancreas. High-fat diet is shown to increase serum lipid levels and enhance fatty infiltration in the pancreas with abnormal adipocytokine production, which may accelerate and enhance pancreatic cancer.

A host of scholarly work has characterized the positive effects of exercise and environmental enrichment on behaviour and cognition in animal studies. The purpose of this study was to investigate the uptake and longitudinal impact of exercise and enrichment on the behavioural phenotype of male and female CD-1 mice. CD-1 mice housed in standard (STD) or exercise and enrichment (EE) conditions post-weaning were tested in the 3-chamber sociability test, open field, and elevated plus maze and exercise activity was monitored throughout the enrichment protocol. Male and female EE mice both showed reduced anxiety and activity in the open field and elevated plus maze relative to sex-matched STD mice. EE altered social behaviours in a sex-specific fashion, with only female EE mice showing increased social preference relative to female STD mice and a preference for social novelty only present in male EE mice. This sexual dimorphism was not observed to be a product of exercise uptake, as CD-1 mice of both sexes demonstrated a consistent trend of wheel rotation frequencies. These findings suggest the importance of considering variables such as sex and strain on experimental design variables in future work on environmental enrichment. Copyright © 2018 Elsevier B.V.

The mechanistic link of ketosis to neuroprotection under certain pathological conditions continues to be explored. We investigated whether chronic ketosis induced by ketogenic diet results in the partitioning of ketone bodies towards oxidative metabolism in brain. We hypothesized that diet-induced ketosis results in increased shunting of ketone bodies towards citric acid cycle (CAC) and amino acids with decreased carbon shunting from glucose. Rats were fed standard (STD) or ketogenic (KG) diets for 3.5 weeks and then infused with [U-13C]glucose or [U-13C]acetoacetate tracers. Concentrations and 13C-labeling pattern of CAC intermediates and amino acids were analyzed from brain homogenates using stable isotopomer mass spectrometry analysis. The contribution of [U-13C]glucose to acetyl-CoA and amino acids decreased by ~30% in the KG group vs STD, whereas [U-13C]acetoacetate contributions were more than 2-fold higher. The concentration of GABA remained constant across all groups; however, the 13C-labeling of GABA was markedly increased in the KG group infused with [U-13C]acetoacetate compared to STD. This study reveals that there is a significant contribution of ketone bodies to oxidative metabolism and GABA in diet-induced ketosis. We propose that this represents a fundamental mechanism of neuroprotection under pathological conditions. PMID:25314677

Differential Epitope Mapping by STD NMR Spectroscopy To Reveal the Nature of Protein-Ligand Contacts.

PubMed

Monaco, Serena; Tailford, Louise E; Juge, Nathalie; Angulo, Jesus

2017-11-27

Saturation transfer difference (STD) NMR spectroscopy is extensively used to obtain epitope maps of ligands binding to protein receptors, thereby revealing structural details of the interaction, which is key to direct lead optimization efforts in drug discovery. However, it does not give information about the nature of the amino acids surrounding the ligand in the binding pocket. Herein, we report the development of the novel method differential epitope mapping by STD NMR (DEEP-STD NMR) for identifying the type of protein residues contacting the ligand. The method produces differential epitope maps through 1) differential frequency STD NMR and/or 2) differential solvent (D 2 O/H 2 O) STD NMR experiments. The two approaches provide different complementary information on the binding pocket. We demonstrate that DEEP-STD NMR can be used to readily obtain pharmacophore information on the protein. Furthermore, if the 3D structure of the protein is known, this information also helps in orienting the ligand in the binding pocket. © 2017 The Authors. Published by Wiley-VCH Verlag GmbH & Co.

The objectives were to study: (1) acceptance of STD screening in non-clinical settings for asymptomatic individuals; (2) risk factors and STD prevalence among individuals in non-clinical and clinical settings; and (3) non-clinical screening of asymptomatic populations as a feasible method for STD control. We recruited 139 males and 486 females between 18 and 30 years of age from a family planning clinic, schools, and community centers in low-income neighborhoods. We asked about STD symptoms and STD/HIV risk behaviors and tested the individuals for gonorrhea, Chlamydia, syphilis, and HIV. Except for HIV, women recruited directly from the community had higher STD rates than those who came in for care at the clinic. Screening in non-clinical settings in Brazil is feasible and has a high yield among young adults in low-income communities. Infected participants would likely never have otherwise sought care or been tested or treated. STD control efforts could be implemented in any site that can reach populations at risk and become a routine procedure in health care settings where people report for problems unrelated to STDs.

To test a novel social network HIV risk-reduction intervention for MSM in Russia and Hungary, where same-sex behavior is stigmatized and men may best be reached through their social network connections. A two-arm trial with 18 sociocentric networks of MSM randomized to the social network intervention or standard HIV/STD testing/counseling. St. Petersburg, Russia and Budapest, Hungary. Eighteen 'seeds' from community venues invited the participation of their MSM friends who, in turn, invited their own MSM friends into the study, a process that continued outward until eighteen three-ring sociocentric networks (mean size = 35 members, n = 626) were recruited. Empirically identified network leaders were trained and guided to convey HIV prevention advice to other network members. Changes in sexual behavior from baseline to 3-month and 12-month follow-up, with composite HIV/STD incidence, measured at 12 months to corroborate behavior changes. There were significant reductions between baseline, first follow-up, and second follow-up in the intervention versus comparison arm for proportion of men engaging in any unprotected anal intercourse (UAI) (P = 0.04); UAI with a nonmain partner (P = 0.04); and UAI with multiple partners (P = 0.002). The mean percentage of unprotected anal intercourse acts significantly declined (P = 0.001), as well as the mean number of UAI acts among men who initially had multiple partners (P = 0.05). Biological HIV/STD incidence was 15% in comparison condition networks and 9% in intervention condition networks. Even where same-sex behavior is stigmatized, it is possible to reach MSM and deliver HIV prevention through their social networks.

The aim was to determine the effects of cafeteria diet (CD) and fish oil supplements given to pregnant and lactating rats on the birth weight and fatty acid profiles of their offspring. Female rats were given standard diet (STD) or CD for 22 days before pregnancy. After mating, some animals remained on STD or CD; for some CD rats, the diet was supplemented with 8.78 % fish oil (CD-FO). After 12 days, half the CD-FO group returned to CD (CD-FO12) and the others remained on CD-FO. At birth, body weights of pups of the three CD groups were lower than STD, maintained until 21 days in the CD-FO group only. At the end of lactation, dams of the CD groups had increased plasma triacylglycerols (TAG), non-esterified fatty acids, and glycerol concentrations, whereas most n-6 long-chain polyunsaturated fatty acids (LCPUFA) were decreased, the effect being greatest in the CD-FO group, where most n-3 LCPUFA were increased and indices of Δ(5) and Δ(6) desaturase activities decreased. The 21-day-old pups of the CD group had increased plasma TAG, not present in the CD-FO group, which had increased 3-hydroxybutyrate concentrations. In both 2- and 21-day-old CD pups, plasma concentrations of ARA were lower than STD, and even lower in the two CD-FO groups. The effect of CD and CD-FO decreasing pups body weight could be related to decreased concentrations of ARA, caused by the inhibition of the Δ(5) and Δ(6) desaturases in the pathway of n-6 LCPUFA biosynthesis.

House mice (Mus musculus domesticus) in Tunisia consists of two races, one carries the 40-acrocentric standard karyotypes and the other one is a robertsonian race (2n=22) homozygous for nine centric fusions (Rb). The F1 hybrids between the two chromosomal races showed a significant decrease in reproductive success and litter size. Such results can be related to the formation of meiotic trivalent in the hybrids leading to the production of viable aneuploid gametes and post-zygotic elimination of embryos due to chromosomal non disjunction events at meiosis. Moreover, testicular histology of F1 and backcross males showed in some cases a breakdown in spermatogenesis. In both females and males, androgens but also estrogens play an important role in gametogenesis. In this study, we have studied aromatase and estrogen receptor alpha (ERalpha) gene expression in the gonads of the two parental races and their chromosomal hybrids. The results showed that aromatase and ERalpha mRNAs are expressed in hybrid males of inter-racial crosses (female22Rb x male40Std and female40Std x male22Rb) and in hybrid females of inter-racial crosses (female22Rb x male40Std) as in the two parental races. However, in hybrid females of inter-racial crosses (female40Std x male22Rb) the amount of aromatase transcripts decreased sharply suggesting that this gene is involved in the breakdown of hybrid fertility in females, but not in males. However, in hybrid males, a putative post-translational modification of this enzyme, in terms of activity, should be verified.

In this study, lung filtration coefficient (Kfc) was measured in eight isolated canine lung preparations by using three methods: standard gravimetric (Std), blood-corrected gravimetric (BC), and optical. The lungs were held in zone III conditions and were subjected to an average venous pressure increase of 8.79 +/- 0.93 (mean +/- SD) cmH2O. The permeability of the lungs was increased with an infusion of alloxan (75 mg/kg). The resulting Kfc values (in milliliters . min-1 . cmH2O-1 . 100 g dry lung weight-1) measured by using Std and BC gravimetric techniques before vs. after alloxan infusion were statistically different: Std, 0.527 +/- 0.290 vs. 1. 966 +/- 0.283; BC, 0.313 +/- 0.290 vs. 1.384 +/- 0.290. However, the optical technique did not show any statistical difference between pre- and postinjury with alloxan, 0.280 +/- 0.305 vs. 0.483 +/- 0. 297, respectively. The alloxan injury, quantified by using multiple-indicator techniques, showed an increase in permeability and a corresponding decrease in reflection coefficient for albumin (sigmaf). Because the optical method measures the product of Kfc and sigmaf, this study shows that albumin should not be used as an intravascular optical filtration marker when permeability is elevated. However, the optical technique, along with another means of measuring Kfc (such as BC), can be used to calculate the sigmaf of a tracer (in this study, sigmaf of 0.894 at baseline and 0.348 after injury). Another important finding of this study was that the ratio of baseline-to-injury Kfc values was not statistically different for Std and BC techniques, indicating that the percent contribution of slow blood-volume increases does not change because of injury.

Sex work is regulated in the Zona Roja (red light district) in Tijuana, Mexico, where HIV and sexually transmitted disease (STD) prevalence is high among female sex workers (FSWs). We examined the spatial distribution of STDs by work venue among FSWs in Tijuana. FSWs aged 18 years and older who reported unprotected sex with ≥ 1 client in the past 2 months underwent testing for HIV, syphilis, gonorrhea, and Chlamydia. HIV/STDs were mapped by venue (i.e., bar, hotel) and Getis-Ord Gi statistics were used to identify geographic hotspots. High-risk venues were then identified using a standardized STD ratio (high risk defined as a ratio ≥ 1.25). Logistic regression was used to assess correlates of working at a high risk venue. Of 474 FSWs, 176 (36.4%) had at least 1 bacterial sexually transmitted infection (STI); 36 (7.6%) were HIV-positive. Within the Zona Roja, 1 venue was identified as a geographic "hotspot," with a higher than expected number of HIV/STD-positive FSW (P < 0.05) as compared to neighboring venues. Using the STD ratio definition, 11 venues were identified as high-risk; FSWs working in these locations had higher education, were more likely to report always using drugs with sex, and having mostly US clients. They were less likely to be registered FSWs or to live at their work venue. A relatively few number of sex work venues accounted for a large proportion of the HIV/STI burden among FSWs in Tijuana. Structural interventions that focus on sex work venues could help increase STI diagnosis, prevention, and treatment among FSWs in Tijuana.

Weight gain in mice on a high caloric diet and chronically treated with omeprazole depends on sex and genetic background

The impact of omeprazole (OM), a widely used over-the-counter proton pump inhibitor, on weight gain has not been extensively explored. We examined what factors, e.g., diet composition, microbiota, genetic strain, and sex, might affect weight gain in mice fed a high caloric diet while on OM. Inbred C57BL/6J strain, a 50:50 hybrid (B6SJLF1/J) strain, and mice on a highly mixed genetic background were fed four diets: standard chow (STD, 6% fat), STD with 200 ppm OM (STD + O), a high-energy chow (HiE, 11% fat), and HiE chow with OM (HiE + O) for 17 wk. Metabolic analysis, body composition, and fecal microbiota composition were analyzed in C57BL/6J mice. Oral glucose tolerance tests were performed using mice on the mixed background. After 8 wk, female and male C57BL/6J mice on the HiE diets ate less, whereas males on the HiE diets compared with the STD diets gained weight. All diet treatments reduced energy expenditure in females but in males only those on the HiE + O diet. Gut microbiota composition differed in the C57BL/6J females but not the males. Hybrid B6SJLF1/J mice showed similar weight gain on all test diets. In contrast, mixed strain male mice fed a HiE + O diet gained ∼40% more weight than females on the same diet. In addition to increased weight gain, mixed genetic mice on the HiE + O diet cleared glucose normally but secreted more insulin. We concluded that sex and genetic background define weight gain and metabolic responses of mice on high caloric diets and OM. PMID:27810953

Objective: The aim of this study was to evaluate whether application of ultralow dose protocols and iterative reconstruction technology (IRT) influence quantitative Hounsfield units (HUs) and contrast-to-noise ratio (CNR) in dentomaxillofacial CT imaging. Methods: A phantom with inserts of five types of materials was scanned using protocols for (a) a clinical reference for navigated surgery (CT dose index volume 36.58 mGy), (b) low-dose sinus imaging (18.28 mGy) and (c) four ultralow dose imaging (4.14, 2.63, 0.99 and 0.53 mGy). All images were reconstructed using: (i) filtered back projection (FBP); (ii) IRT: adaptive statistical iterative reconstruction-50 (ASIR-50), ASIR-100 and model-based iterative reconstruction (MBIR); and (iii) standard (std) and bone kernel. Mean HU, CNR and average HU error after recalibration were determined. Each combination of protocols was compared using Friedman analysis of variance, followed by Dunn's multiple comparison test. Results: Pearson's sample correlation coefficients were all >0.99. Ultralow dose protocols using FBP showed errors of up to 273 HU. Std kernels had less HU variability than bone kernels. MBIR reduced the error value for the lowest dose protocol to 138 HU and retained the highest relative CNR. ASIR could not demonstrate significant advantages over FBP. Conclusions: Considering a potential dose reduction as low as 1.5% of a std protocol, ultralow dose protocols and IRT should be further tested for clinical dentomaxillofacial CT imaging. Advances in knowledge: HU as a surrogate for bone density may vary significantly in CT ultralow dose imaging. However, use of std kernels and MBIR technology reduce HU error values and may retain the highest CNR. PMID:26859336

Background The Government of Ghana has been implementing various health sector reforms (e.g. user fees in public health facilities, decentralization, sector-wide approaches to donor coordination) in a bid to improve efficiency in health care. However, to date, except for the pilot study reported in this paper, no attempt has been made to make an estimate of the efficiency of hospitals and/or health centres in Ghana. The objectives of this study, based on data collected in 2000, were: (i) to estimate the relative technical efficiency (TE) and scale efficiency (SE) of a sample of public hospitals and health centres in Ghana; and (ii) to demonstrate policy implications for health sector policy-makers. Methods The Data Envelopment Analysis (DEA) approach was used to estimate the efficiency of 17 district hospitals and 17 health centres. This was an exploratory study. Results Eight (47%) hospitals were technically inefficient, with an average TE score of 61% and a standard deviation (STD) of 12%. Ten (59%) hospitals were scale inefficient, manifesting an average SE of 81% (STD = 25%). Out of the 17 health centres, 3 (18%) were technically inefficient, with a mean TE score of 49% (STD = 27%). Eight health centres (47%) were scale inefficient, with an average SE score of 84% (STD = 16%). Conclusion This pilot study demonstrated to policy-makers the versatility of DEA in measuring inefficiencies among individual facilities and inputs. There is a need for the Planning and Budgeting Unit of the Ghana Health Services to continually monitor the productivity growth, allocative efficiency and technical efficiency of all its health facilities (hospitals and health centres) in the course of the implementation of health sector reforms.

We reviewed charts of newly diagnosed STD patients in three health facilities to determine the proportion who received follow-up STD screening. In a 12-month period, the three facilities had 140 STD cases. STD screening was not indicated for 50 (36%) patients. Among the 90 remaining STD patients, 29 (32%) were screened and 61 (68%) not screened. Among non-screened patients, 36% (22/61) were tested, but outside the time parameters allowed by the audit. The remaining 64% (39/61) received no screening at all, and represented clinical missed opportunities; in this group, nearly all (95%) had chlamydia but were not screened for HIV or syphilis. Linking chlamydia patients with a screen for HIV and syphilis using a clinical reminder in the facilities' electronic health record (EHR) or other tool, would eliminate 95% of the missed opportunities in this sample.

Airborne hygrometry is often demanded in scientific flight campaigns to provide datasets for environmental modeling or to correct for water vapor dilution or cross sensitivity effects in other gas analytical techniques. Water vapor measurements, however, are quite challenging due to the large dynamic range in the atmosphere (between 2 and 40000 ppmv) and the high spatio-temporal variability. Airborne hygrometers therefore need to combine a large measurement range with high temporal resolution to resolve - at typical airspeeds of 500 to 900 km/h - atmospheric gradients of several 1000 ppmv/s. Especially during the ascent into the upper troposphere, hygrometers need to work at high gas exchange rates to minimize water vapor adsorption effects. On the other hand, water vapor sensors are difficult to calibrate due to the strong water adsorption and the lack of bottled reference gas standards, which requires pre- or/and post-flight field calibrations. Recently in-flight calibration using an airborne H2O generator was demonstrated, which minimizes calibration drift but still imposes a lot of additional work and hardware to the experiments, since these kind of calibrations just transfer the accuracy level issues to the in-flight calibration-source. To make things worse, the low gas flow (1-5 std l/min, compared with up to 100 std l/min in flight for fast response instruments) adheres critical questions of wall absorption/desorption of the source and instrument even during the calibration process. The national metrological institutes (NMIs) maintain a global metrological water vapor scale which is defined via national primary humidity generators. These provide for calibration purposes well-defined, accurate water vapor samples of excellent comparability and stability traced back to the SI-units. The humidity calibration chain is maintained via high accuracy (but rather slow) Dew-Point-Mirror-Hygrometers as transfer standards. These provide a traceable performance and calibration link to any industrial or research laboratory hygrometer. To establish metrological traceability in field and particular in airborne hygrometers is however challenging and requires fast, field-compatible, metrologically qualified transfer hygrometry standards to link the metrological and the environmental sciences water scales. The SEALDH (Selective Extractive Airborne Laser Diode Hygrometer) development started 3 years ago and aims at filling this gap by using Tunable Diode Laser Absorption Spectroscopy (TDLAS) with a special, calibration-free data evaluation [1]. Previously developed, laboratory-based TDLAS instruments, such as [2] [3], were starting points to develop an autonomously operating, extractive water vapor sensor in a compact 19' 4 HU form factor. This new airborne package and far-reaching developments [4] in hard- and software allow an autonomous, low maintenance, airborne operation. SEALDH-II can be used in a calibration-free field sensor mode (with an absolute, metrologically defined uncertainty of 4.3% +- 3ppmv). The response time is mainly limited by the gas flow and significantly below 1 sec with a precision down to 0.08 ppmv (1σ, 1sec) measured at 600 ppmv and 1000 hPa. The excellent long-term stability of SEALDH-II (

In April 2008, experts reviewed updates on sexually transmitted disease (STD) prevention and treatment in preparation for the revision of the Centers for Disease Control and Prevention (CDC) STD Treatment Guidelines. This included a review of cervical cancer screening in the STD clinical setting. Key questions were identified with assistance from an expert panel. Reviews of the literature were conducted using the PubMed computerized database and shared with the panel. Updated information was incorporated in the 2010 CDC STD Treatment Guidelines. We recommend that STD clinics offering cervical screening services screen and treat women according to guidelines by the American College of Obstetrics and Gynecology, the American Cancer Society, the US Preventive Services Task Force, and the American Society for Colposcopists and Cervical Pathologists. New to the 2010 guidelines are higher age for initiating cervical screening (age ≥ 21 years) and less frequent intervals of screening (at least every 3 years). New recommendations include new technologies, such as liquid-based cytology and high-risk human papillomavirus (HPV) DNA tests. Liquid-based technologies are not recommended over conventional testing. HPV DNA tests are recommended as adjunct tests and with new indications for use in cervical screening and management. Stronger recommendations were issued for STD clinics offering cervical screening services to have protocols in place for follow-up of test results and referral (eg, colposcopy). Important additions to the 2010 STD Treatment Guidelines include information on updated algorithms for screening and management of women and recommendations for use of liquid-based cytology and high-risk HPV testing.

Sexually transmitted diseases (STDs) are increasing among gay, bisexual, and other men who have sex with men (MSM). Little is known about the use of websites and mobile phone applications to meet sexual partners ("hookup sites") and association with STD diagnoses. We performed a demographic and behavioral assessment of 415 MSM presenting to the Rhode Island STD clinic. Bivariate and multivariable analyses assessed associations between using hookup sites and testing positive for syphilis, gonorrhea, or chlamydia. Venue-based affiliation networks were created to evaluate hookup sites and their association with STD diagnoses. Among 415 MSM, 78% reported meeting a partner online in the last 12 months, and 25% tested positive for at least one STD. Men who met partners online were more likely to be white (67% vs. 54%, P = 0.03) and have more than 10 lifetime partners (87% vs. 58%, P < 0.05). The most commonly used hookup sites included Grindr (78%), Scruff (35%), and Tinder (22%). In the multivariable analysis, only Scruff use was associated with testing positive for an STD (odds ratio, 2.28; 95% confidence interval, 1.09-4.94). However, among men who met partners online, 75% of men diagnosed as having an STD had met a sexual partner on Grindr, including 100% of those who were diagnosed as having gonorrhea. Use of hookup sites was nearly ubiquitous among MSM undergoing STD screening. Specific hookup sites were significantly associated with STD diagnoses among MSM. Greater efforts are needed to promote STD screening and prevention among MSM who meet partners online.

This study compared the dosimetric performance of (a) volumetric modulated arc therapy (VMAT) with standard optimization (STD) and (b) multi-criteria optimization (MCO) to (c) intensity modulated radiation therapy (IMRT) with MCO for hippocampal avoidance whole brain radiation therapy (HA-WBRT) in RayStation treatment planning system (TPS). Ten HA-WBRT patients previously treated with MCO-IMRT or MCO-VMAT on an Elekta Infinity accelerator with Agility multileaf collimators (5-mm leaves) were re-planned for the other two modalities. All patients received 30 Gy in 15 fractions to the planning target volume (PTV), namely, PTV30 expanded with a 2-mm margin from the whole brain excluding hippocampus with margin. The patients all had metastatic lesions (up to 12) of variable sizes and proximity to the hippocampus, treated with an additional 7.5 Gy from a simultaneous integrated boost (SIB) to PTV37.5. The IMRT plans used eight to eleven non-coplanar fields, whereas the VMAT plans used two coplanar full arcs and a vertex half arc. The averaged target coverage, dose to organs-at-risk (OARs) and monitor unit provided by the three modalities were compared, and a Wilcoxon signed-rank test was performed. MCO-VMAT provided statistically significant reduction of D100 of hippocampus compared to STD-VMAT, and Dmax of cochleas compared to MCO-IMRT. With statistical significance, MCO-VMAT improved V30 of PTV30 by 14.2% and 4.8%, respectively, compared to MCO-IMRT and STD-VMAT. It also raised D95 of PTV37.5 by 0.4 Gy compared to both MCO-IMRT and STD-VMAT. Improved plan quality parameters such as a decrease in overall plan Dmax and total monitor units (MU) were also observed for MCO-VMAT. MCO-VMAT is found to be the optimal modality for HA-WBRT in terms of PTV coverage, OAR sparing and delivery efficiency, compared to MCO-IMRT or STD-VMAT. © 2018 The Authors.

Advancements in technology, such as geographic information systems (GIS), expand sexually transmitted disease (STD) program capacity for data analysis and visualization, and introduce additional confidentiality considerations. We developed a survey to examine GIS use among STD programs and to better understand existing data confidentiality practices. A Web-based survey of eight to 22 questions, depending on program-specific GIS capacity, was e-mailed to all STD program directors through the National Coalition of STD Directors in November 2004. Survey responses were accepted until April 15, 2005. Eighty-five percent of the 65 currently funded STD programs responded to the survey. Of those, 58% used GIS and 54% used geocoding. STD programs that did not use GIS (42%) identified lack of training and insufficient staff as primary barriers. Mapping, spatial analyses, and targeting program interventions were the main reasons for geocoding data. Nineteen of the 25 programs that responded to questions related to statistical disclosure rules employed a numerator rule, and 56% of those used a variation of the "Rule of 5." Of the 28 programs that responded to questions pertaining to confidentiality guidelines, 82% addressed confidentiality of GIS data informally. Survey findings showed the increasing use of GIS and highlighted the struggles STD programs face in employing GIS and protecting confidentiality. Guidance related to data confidentiality and additional access to GIS software and training could assist programs in optimizing use of spatial data.

The std operon encodes a fimbrial adhesin of Salmonella enterica serotype Typhimurium that is required for attachment to intestinal epithelial cells and for cecal colonization in the mouse. To study the mechanism by which this virulence factor contributes to colonization we characterized its binding specificity. Std-mediated binding to human colonic epithelial (Caco-2) cells could be abrogated by removing N-linked glycans. Adherence of Std fimbriated S. Typhimurium to Caco-2 cells could be blocked by co-incubation with H type 2 oligosaccharide (Fucalpha1-2Galbeta1-4GlcNAc) or by pretreatment of cells with alpha1-2 fucosidase. In contrast, pretreatment of Caco-2 cells with neuraminidase or co-incubation with the type 2 disaccharide precursor (Galbeta1-4GlcNAc) did not reduce adherence of Std fimbriated S. Typhimurium. Binding of purified Std fimbriae to Fucalpha1-2Galbeta1-4GlcNAc in a solid phase binding assay was competitively inhibited by Ulex europaeus agglutinin-I (UEA-I), a lectin specific for Fucalpha1-2 moieties. Purified Std fimbriae and UEA both bound to a receptor localized in the mucus layer of the murine cecum. These data suggest that the std operon encodes an adhesin that binds an alpha1-2 fucosylated receptor(s) present in the cecal mucosa.

College years are a time young adults examine high-risk sexual behaviors, increasing their risk for sexually transmitted diseases (STDs). Fraternity/sorority membership has been identified as one factor contributing to increased risky sexual behavior in college students. This study measured the effectiveness of an educational intervention targeting STD prevention in fraternity and sorority members, and examined relationships between STD knowledge, attitudes, and demographics. A descriptive, correlational design was used. Pre- and posttest data were collected from fraternity and sorority members (N = 132). Instruments measured demographic characteristics, STD knowledge, and attitudes toward safe sex behaviors. There was a significant increase in STD knowledge from baseline (M = 13.03, SD = 6.5) to 1 week (M = 20.27, SD = 4.9) t (131) = -13.53, p = .000. Males were more likely to report attitudes toward risky sexual behavior rs(132) = .323, p = .000, and as knowledge increased, attitudes became more favorable to safe sex behaviors (pre-STD knowledge and preintervention attitudes, r(132) = -.249, p = .004; post-STD knowledge and postintervention attitudes, rs(132) = -.307, p = .000). Results support that brief STD educational interventions can increase STD knowledge. College health centers must aim to provide sexual health education to all students at every visit. ©2016 American Association of Nurse Practitioners.

Improving STD testing behavior among high-risk young adults by offering STD testing at a vocational school.

Chlamydia trachomatis infection (CT) is the most prevalent bacterial STD. Sexually active adolescents and young adults are the main risk group for CT. However, STD testing rates in this group are low since exposed individuals may not feel at risk, owing-at least in part-to the infection's largely asymptomatic nature. Designing new testing environments that are more appealing to young people who are most at risk of acquiring chlamydia can be an important strategy to improve overall testing rates. Here we evaluate the effect of a school-based sexual health program conducted among vocational school students, aiming to obtain better access for counseling and enhance students' STD testing behavior. Adolescents (median age 19 years) attending a large vocational school were provided with sexual health education. Students filled in a questionnaire measuring CT risk and were offered STD testing. Using univariate and multivariate analysis, we assessed differences between men and women in STD-related risk behavior, sexual problems, CT testing behavior and determinants of CT testing behavior. Of 345 participants, 70% were female. Of the 287 sexually active students, 75% were at high risk for CT; one third of women reported sexual problems. Of sexually active participants, 61% provided a self-administered specimen for STD testing. Independent determinants for testing included STD related symptoms and no condom use. All CT diagnoses were in the high-CT-risk group. In the high-risk group, STD testing showed an increased uptake, from 27% (previous self-reported test) to 65% (current test). CT prevalence was 5.7%. Vocational school students are a target population for versatile sexual health prevention. When provided with CT testing facilities and education, self selection mechanisms seemed to increase CT testing rate dramatically in this high-CT-risk population expressing sexual problems. Considering the relative ease of testing and treating large numbers of young adults, offering tests at a vocational school is feasible in reaching adolescents for STD screening. Although cost-effectiveness remains an issue counseling is effective in increasing test rates.

The Hazards Mitigation Center at Lawrence Livermore National Laboratory (LLNL) updated the seismic hazard and design parameters at the Pantex Plant. The probabilistic seismic hazard (PSH) estimates were first updated using the latest available data and knowledge from LLNL (1993, 1998), Frankel et al. (1996), and other relevant recent studies from several consulting companies. Special attention was given to account for the local seismicity and for the system of potentially active faults associated with the Amarillo-Wichita uplift. Aleatory (random) uncertainty was estimated from the available data and the epistemic (knowledge) uncertainty was taken from results of similar studies. Special attentionmore » was given to soil amplification factors for the site. Horizontal Peak Ground Acceleration (PGA) and 5% damped uniform hazard spectra were calculated for six return periods (100 yr., 500 yr., 1000 yr., 2000 yr., 10,000 yr., and 100,000 yr.). The design parameters were calculated following DOE standards (DOE-STD-1022 to 1024).

Obesity and type 2 diabetes mellitus (T2DM) are occurring at epidemic-like rates, and these epidemics appear to have emerged largely from changes in daily diet. In the present study, we compared effects of high-fat diet (HFD) and fructose-rich diet (FRD) in WBN/Kob-Lepr fa (WBKDF) rats that spontaneously develop obesity, dyslipidemia and T2DM. After a 4-week feeding of each diet, WBKDF-HFD and WBKDF-FRD rats exhibited aggravated obesity and dyslipidemia compared with WBKDF rats fed standard diet (STD). In contrast, hyperglycemia developed in WBKDF-STD rats was significantly inhibited in WBKDF-FRD rats, but not in WBKDF-HFD rats. The present study demonstrated that the 4-week feeding of HFD and FRD caused diet-induced obesity with a distinct phenotype in the glucose metabolism in WBKDF rats.

A torso phantom with simulated nodules [diameter: 5, 8, 10, and 12 mm; computed tomography (CT) density: - 630 HU] was scanned with a multi-detector CT at tube currents of 10 mA (ultra-low-dose: UL-dose) and 270 mA (standard-dose: Std-dose). Images were reconstructed with filtered back projection [FBP; standard (Std-FBP), ultra-low-dose (UL-FBP)], FIRST Lung (UL-Lung), and FIRST Body (UL-Body), and analyzed with a semi-automatic software. The error in the volume measurement was determined. The errors with UL-Lung and UL-Body were smaller than that with UL-FBP. The smallest error was 5.8% ± 0.3 for the 12-mm nodule with UL-Body (middle lung). Our results indicated that FIRST Body would be superior to FIRST Lung in terms of accuracy of nodule measurement with UL-dose CT.

Young people (15-24 years) in the United States are disproportionately affected by infection with human immunodeficiency virus (HIV) and sexually transmitted diseases (STD). Shortfalls in HIV/STD-related knowledge, attitudes, beliefs, and behavioral intentions (KABI) likely contribute to this discrepancy. In this report we describe our experience developing a novel means of health communication combining entertainment-education theory and recent technological advances to create a HIV/STD-focused "motion comic." We also report the audience satisfaction and acceptance of the intervention. We used the Health Belief Model (HBM), entertainment-education (EE) principles, and the Sabido Method (SM) and conducted three rounds of focus groups to develop a 38-minute HIV/STD focused motion comic for young people between the ages 15 and 24 years. Participants indicated that motion comics were an acceptable method of delivering HIV/STD prevention messages. They also expressed satisfaction with motion comics plot, story settings, the tone of humor, and drama. Our results suggest that motion comics are a viable new method of delivering health communication messages about HIV/STD and other public health issues, and warrant further development and broader evaluation.

Fast response and high sensitivity to microsaccades in a cascading-adaptation neural network with short-term synaptic depression

NASA Astrophysics Data System (ADS)

Yuan, Wu-Jie; Zhou, Jian-Fang; Zhou, Changsong

2016-04-01

Microsaccades are very small eye movements during fixation. Experimentally, they have been found to play an important role in visual information processing. However, neural responses induced by microsaccades are not yet well understood and are rarely studied theoretically. Here we propose a network model with a cascading adaptation including both retinal adaptation and short-term depression (STD) at thalamocortical synapses. In the neural network model, we compare the microsaccade-induced neural responses in the presence of STD and those without STD. It is found that the cascading with STD can give rise to faster and sharper responses to microsaccades. Moreover, STD can enhance response effectiveness and sensitivity to microsaccadic spatiotemporal changes, suggesting improved detection of small eye movements (or moving visual objects). We also explore the mechanism of the response properties in the model. Our studies strongly indicate that STD plays an important role in neural responses to microsaccades. Our model considers simultaneously retinal adaptation and STD at thalamocortical synapses in the study of microsaccade-induced neural activity, and may be useful for further investigation of the functional roles of microsaccades in visual information processing.

Psychological reactions to sexually transmissible disease (STD) infection are common, occurring in up to 85% of some patients with STDs: Hart has suggested that they are among the most common conditions encountered in venereology. Previous psychiatric disturbances in STD patients, however, are relatively uncommon and differ in both etiology and management from such psychological sequelae of STD infection, although both Catalan et al. and Fitzpatrick et al. report that in the United Kingdom, some 40% of STD clinic attenders had General Health Questionnaire scores indicating they were psychiatric cases.

Man-systems requirements for the control of teleoperators in space

NASA Technical Reports Server (NTRS)

Shields, Nicholas L., Jr.

1988-01-01

The microgravity of the space environment has profound effects on humans and, consequently, on the design requirements for subsystems and components with which humans interact. There are changes in the anthropometry, vision, the perception of orientation, posture, and the ways in which we exert energy. The design requirements for proper human engineering must reflect each of the changes that results, and this is especially true in the exercise of control over remote and teleoperated systems where the operator is removed from any direct sense of control. The National Aeronautics and Space Administration has recently completed the first NASA-wide human factors standard for microgravity. The Man-Systems Integration Standard, NASA-STD-3000, contains considerable information on the appropriate design criteria for microgravity, and there is information that is useful in the design for teleoperated systems. There is not, however, a dedicated collection of data which pertains directly to the special cases of remote and robotic operations. The design considerations for human-system interaction in the control of remote systems in space are discussed, with brief details on the information to be found in the NASA-STD-3000, and arguments for a dedicated section within the Standard which deals with robotic, teleoperated and remote systems and the design requirements for effective human control of these systems in the space environment, and from the space environment.

We evaluated emergency department (ED) provider adherence to guidelines for concurrent HIV-sexually transmitted disease (STD) testing within an expanded HIV testing program and assessed demographic and clinical factors associated with concurrent HIV-STD testing. We examined concurrent HIV-STD testing in a suburban academic ED with a targeted, expanded HIV testing program. Patients aged 18-64 years who were tested for syphilis, gonorrhea, or chlamydia in 2009 were evaluated for concurrent HIV testing. We analyzed demographic and clinical factors associated with concurrent HIV-STD testing using multivariate logistic regression with a robust variance estimator or, where applicable, exact logistic regression. Only 28.3% of patients tested for syphilis, 3.8% tested for gonorrhea, and 3.8% tested for chlamydia were concurrently tested for HIV during an ED visit. Concurrent HIV-syphilis testing was more likely among younger patients aged 25-34 years (adjusted odds ratio [AOR] = 0.36, 95% confidence interval [CI] 0.78, 2.10) and patients with STD-related chief complaints at triage (AOR=11.47, 95% CI 5.49, 25.06). Concurrent HIV-gonorrhea/chlamydia testing was more likely among men (gonorrhea: AOR=3.98, 95% CI 2.25, 7.02; chlamydia: AOR=3.25, 95% CI 1.80, 5.86) and less likely among patients with STD-related chief complaints at triage (gonorrhea: AOR=0.31, 95% CI 0.13, 0.82; chlamydia: AOR=0.21, 95% CI 0.09, 0.50). Concurrent HIV-STD testing in an academic ED remains low. Systematic interventions that remove the decision-making burden of ordering an HIV test from providers may increase HIV testing in this high-risk population of suspected STD patients.

To understand the willingness on acceptance of a short-messageservice (SMS) program provided for HIV/STD testing and the related factors, among male clients at the STD clinics in China. Convenience sampling method was used to select study subjects at a STD clinic in Wuxi, Jiangsu province. A questionnaire survey was conducted among the subjects to collect the information on socio-demographic characteristics and willingness of acceptance to the SMS. A total of 368 SMS subjects were surveyed, in which 75.5% expressed the willingness of acceptance, while 57.2% and 38.1% of them wanted to receive the short message every 3 months or 6 months, respectively. 53.8% of the respondents showed their willingness to share the news with their sexual partners about SMS and 44.8% of them would do the same to their friends. Data from the Multivariate logistic regression analysis showed that those who had received senior high school or above education (aOR=3.632, 95%CI: 1.939-6.715) , having homosexual behavior (aOR = 1.973, 95%CI: 1.234-8.358) or those having received AIDS related intervention service in the past year (aOR=9.416, 95%CI: 4.822-18.309) were more likely to accept the SMS. SMS seemed to be acceptable among the male STD clinic clients in Wuxi, suggesting that it is feasible to conduct the SMS as a strategy to improve the HIV/STDs testing program at the STD clinics in the future. Promotion of SMS should be strengthened and the provision of general AIDS intervention service at the STD clinics should be established in order to make more STD clinic clients understand this SMS.

State laws related to billing third parties for healthcare services at public STD clinics in the United States.

2018-02-07

Health departments (HDs) cite state laws as barriers to billing third parties for sexually transmitted disease (STD) services, but the association between legal/policy barriers and third party HD billing has not been examined. This study investigates the relationship between laws that may limit HDs' ability to bill, clinic perceptions of billing barriers, and billing practices. Two surveys (1) clinic managers [N=246], 2) STD program managers [N=63]) conducted via a multi-regional needs assessment of federally funded HD clinics' capacity to bill for STD services, billing/reimbursement practices, and perceived barriers were combined with an analysis of state laws regarding third party billing for STD services. Statistical analyses examined relationships between laws that may limit HDs' ability to bill, clinic perceptions, and billing practices. Clinic managers reported clinics were less likely to bill Medicaid and other third parties in jurisdictions with a state law limiting their ability to bill compared to respondents who billed neither or one payer (OR=0.31, CI=0.10,0.97) and cited practical concerns as a primary barrier to billing (OR=2.83 CI=1.50,5.37). STD program managers' reports that staff believed STD services should be free (OR=0.34, CI=0.13, 0.90) was associated with not billing (not sure versus no resistance to billing); confidentiality concerns was not a reported barrier to billing among either sample. Practical concerns and clinic staff beliefs that STD services should be free emerged as possible barriers to billing, and laws less so. Attempts to initiate HD billing for STD services may benefit from staff education as well as addressing perceived legal barriers and staff concerns.

Trends in Receipt of Sexually Transmitted Disease Services Among Women 15 to 44 Years Old in the United States, 2002 to 2006–2010

Background To describe recent trends in the receipt of sexually transmitted disease (STD) services among women (age, 15–44 years) from 2002 to 2006–2010 using the National Survey of Family Growth. Methods We analyzed trends in demographics, health insurance, and visit-related variables of women reporting receipt of STD services (counseling, testing, or treatment) in the past 12 months. We also analyzed trends in the source of STD services and the payment method used. Results Receipt of STD services reported by women in the past 12 months increased from 2002 (12.6%) to 2006–2010 (16.0%; P < 0.001). Receipt of services did not increase among adolescents (P = 0.592). Among women receiving STD services from a private doctor/HMO, the percentage with private insurance decreased over time (74.6%–66.8%), whereas the percentage with Medicaid increased (12.8%–19.7%; P = 0.020). For women receiving STD services at a public clinic or nonprimary care facility, there were no statistically significant differences by demographics, except that fewer adolescents but more young adults reported using a public clinic over time (P = 0.038). Among women who reported using Medicaid as payment, receipt of STD services at a public clinic significantly decreased (36.8%–25.4%; P = 0.019). For women who paid for STD services with private insurance, the only significant difference was an increase in having a copay over time (61.3%–70.1%; P = 0.012). Conclusions Despite a significant increase in receipt of STD services over time, many women at risk for STDs did not receive services including adolescents. In addition, we identified important shifts in payment methods during this time frame. PMID:24335746

Narrative Review: Sexually Transmitted Diseases and Homeless Youth-What Do We Know About Sexually Transmitted Disease Prevalence and Risk?

Homelessness affects an estimated 1.6 million US youth annually. Compared with housed youth, homeless youth are more likely to engage in high-risk behaviors, including inconsistent condom use, multiple sex partners, survival sex, and alcohol/drug use, putting them at increased sexually transmitted disease (STD) risk. However, there is no national estimate of STD prevalence among this population. We identified 10 peer-reviewed articles (9 unique studies) reporting STD prevalence among homeless US youth (2000-2015). Descriptive and qualitative analyses identified STD prevalence ranges and risk factors among youth. Eight studies reported specific STD prevalence estimates, mainly chlamydia, gonorrhea, and syphilis. Overall STD prevalence among homeless youth ranged from 6% to 32%. STD rates for girls varied from 16.7% to 46%, and from 9% to 13.1% in boys. Most studies were conducted in the Western United States, with no studies from the Southeast or Northeast. Youths who experienced longer periods of homelessness were more likely to engage in high-risk sexual behaviors. Girls had lower rates of condom use and higher rates of STDs; boys were more likely to engage in anal and anonymous sex. Additionally, peer social networks contributed to protective effects on individual sexual risk behavior. Sexually transmitted disease prevalence estimates among homeless youth fluctuated greatly by study. Sexually transmitted disease risk behaviors are associated with unmet survival needs, length of homelessness, and influence of social networks. To promote sexual health and reduce STD rates, we need better estimates of STD prevalence, more geographic diversity of studies, and interventions addressing the behavioral associations identified in our review.

A transportable 50 kA dual mode lightning simulator

NASA Technical Reports Server (NTRS)

Salisbury, K.; Lloyd, S.; Chen, Y. G.

1991-01-01

A transportable lightning simulator was designed, built and tested, which is capable of delivering more than 50 kA to an 8 micro-H test object. The simulator was designed to be a versatile device in the lightning laboratory while meeting the requirements of MIL-STD-1757A for component E current waveforms. The system is capable of operating in either a ringing mode with a Q greater than 5 and a nominal frequency of 160 kHz, or a unipolar mode with no hardware configuration changes. The ringing mode is obtained by the LCR series circuit formed by the pulse generator and test object. The unipolar mode is obtained by closing an electrically triggered crowbar switch at peak current. The simulator exceeds the peak current requirement and rate of rise requirements for MIL-STD-1757A in both the ringing and unipolar modes. The pulse half width in the unipolar mode is in excess of 50 microsec and the action is in excess of 10(exp 5) A(exp 2)s. The design, component values, and test results are presented.

[The practice guideline 'The STD consultation' from the Dutch College of General Practitioners; a response from the perspective of dermatology].

PubMed

Neumann, H A M

2005-08-06

Sexually transmitted diseases (STDs) constitute an important health problem in the Netherlands. Although there are several STD outpatient clinics, such facilities remain unavailable outside the larger cities. The members of the Dutch College of General Practitioners, who published the practice guideline on STD consultation, provide the majority of STD care. An important aspect of this guideline is the fact that GPs are able to assess the risk by taking a sexual history and then determine their own policy on additional investigations. This prevents the omission of investigations that would exclude an STD, but carries the risk, at least theoretically, that it may be missed. It is noteworthy that scabies is not discussed in these guidelines. The most important difference between the guidelines followed by dermatological/STD clinics throughout the Netherlands is the level of triage practiced by GPs. It seems that GPs have a well-thought out and responsible policy, which also merits attention from dermatologists/venereologists.

Age Differences in STDs, Sexual Behaviors, and Correlates of Risky Sex Among Sexually Experienced Adolescent African-American Females

Objective To explore age differences in factors associated with positive sexually transmitted diseases (STD) status among a sample of African-American adolescent females. Methods Data were collected via ACASI from 701 African-American adolescent females (14–20 years) seeking services at reproductive health clinics. Adolescents provided self-collected vaginal swabs assayed using NAAT to assess the prevalence of three STDs. Results Younger adolescents (14–17 years) had significantly higher rates of STDs than older adolescents (18–20 years), but older adolescents had significantly higher levels of STD-associated risk behavior. In controlled analysis, having a casual sex partner was the only variable significantly associated with a positive STD test for younger adolescents, and prior history of STD and higher impulsivity were significantly associated with testing STD positive among older adolescents. Conclusions These findings suggest that developmentally tailored STD/HIV prevention interventions are needed for younger and older subgroups of adolescent females to help reduce their risk of infection.

To determine productivity loss and indirect costs with deep vein thrombosis (DVT) and pulmonary embolism (PE). Medical and pharmacy claims with short-term disability (STD) and long-term disability (LTD) claims from 2007 to 2010 were analyzed from the Integrated Benefits Institute's Health and Productivity Benchmarking (IBI-HPB) database (STD and LTD claims) and IMS LifeLink™ data (medical and pharmacy claims), which were indirectly linked using a weighting approach matching from IBI-HPB patients' demographic distribution. A total of 5442 DVT and 6199 PE claims were identified. Employees with DVT lost 57 STD and 440 LTD days per disability incident. The average per claim productivity loss from STD and LTD was $7414 and $58181, respectively. Employees with PE lost 56 STD and 364 LTD days per disability incident. The average per claim productivity loss from STD and LTD was $7605 and $48,751, respectively. Deep vein thrombosis and PE impose substantial economic burdens.

Evaluation of D-1 tape and cassette characteristics: Moisture content of Sony and Ampex D-1 tapes when delivered

Ashton, Gary

Commercial D-1 cassette tapes and their associated recorders were designed to operate in broadcast studios and record in accordance with the International Radio Consultative Committee (CCIR) 607 digital video standards. The D-1 recorder resulted in the Society of Motion Picture and Television Engineers (SMPTE) standards 224 to 228 and is the first digital video recorder to be standardized for the broadcast industry. The D-1 cassette and associated media are currently marketed for broadcast use. The recorder was redesigned for data applications and is in the early stages of being evaluated. The digital data formats used are specified in MIL-STD-2179 and the American National Standards Institute (ANSI) X3.175-190 standard. In early 1990, the National Media Laboratory (NML) was asked to study the effects of time, temperature, and relative humidity on commercial D-1 cassettes. The environmental range to be studied was the one selected for the Advanced Tactical Air Reconnaissance System (ATARS) program. Several discussions between NML personnel, ATARS representatives, recorder contractors, and other interested parties were held to decide upon the experimental plan to be implemented. Review meetings were held periodically during the course of the experiment. The experiments were designed to determine the dimensional stability of the media and cassette since this is one of the major limiting factors of helical recorders when the media or recorders are subjected to non-broadcasting environments. Measurements were also made to characterize each sample of cassettes to give preliminary information on which purchase specifications could be developed. The actual tests performed on the cassettes and media before and after aging fall into the general categories listed.

A qualitative study of rural black adolescents' perspectives on primary STD prevention strategies.

PubMed

Akers, Aletha Y; Gold, Melanie A; Coyne-Beasley, Tamera; Corbie-Smith, Giselle

2012-06-01

Primary STD prevention relies on five key strategies: practicing abstinence, choosing low-risk partners, discussing partners' sexual history, using condoms consistently and not having multiple partners. Few studies have examined all of these strategies simultaneously, and few have focused on rural black adolescents, whose rates of early sexual initiation and STDs are among the highest in the nation. In 2006, a sample of 37 black adolescents (20 female, 17 male) from two rural North Carolina counties participated in focus groups that explored their understanding of how primary prevention strategies reduce STD transmission, the common barriers they encounter in trying to adopt these strategies and the risk reduction strategies that they employ. Transcripts were analyzed using a grounded theory approach. Adolescents understood how primary prevention strategies reduce STD transmission. However, they perceived sex as normal and abstinence as unlikely during adolescence. Furthermore, they considered the remaining primary prevention strategies difficult to implement because these strategies depend on partner cooperation and incorrectly assume that STD prevention is paramount when adolescents make sexual decisions. Adolescents reported using alternative strategies to reduce their STD risk; the most commonly used approaches were indirect assessments of partner characteristics (e.g., evaluating partners' physical appearance and sexual history) and STD testing (to identify and treat infections). Adolescents try to reduce their STD risk, but do so by using ineffective practices. Promoting primary prevention strategies requires helping adolescents to identify opportunities to successfully employ these strategies. Copyright © 2012 by the Guttmacher Institute.

STD education: challenge for the 80s.

Discussion focuses on 3 aspects of sexually transmitted diseases (STD) education: the need for and appropriateness of school-based STD education; some elements of timely, high quality STD education; and strategies for dealing constructively with controversy. More than half of the estimated 20 million STD victims in the US this year will be persons under age 25. Almost 1/4 will be victims of STD before they receive their high school diplomas. STD are the most pervasive, destructive, and expensive communicable disease problems facing American youth. If the twin criteria of true experimental design and of measuring appropriate outcomes are applied to published studies, then the effectiveness of classroom STD education has not as yet been properly evaluated. The evaluation criteria which should be applied to health education programs are uniquely based on nonacademic goals, that is, ultimate outcomes are generally not observable in the academic environment. The federal government has been virtually precluded from supporting or conducting appropriate behavioral studies because of laws protecting individual privacy, and most school systems are similarly restricted when it comes to asking students about their personal or family lives, of which sexual matters are among the most intimate. Programs designed according to accepted concepts of learning and decision making need to be implemented, even if their benefits must be regarded as potential, until such time as research obstacles can be resolved. STD education objectives should be drawn from the behaviors relevant to the prevention, acquisition, transmission, and disposition of an STD. The behaviors are organized into 5 behavioral sets and described here as decision steps: decisions about when, how, and with whom to engage in sexual behavior; decisions specific to health protection if sexual behavior includes genital contact; decisions in response to suspected illness; decisions in response to diagnosed disease; and decisions related to other people. Within each decision step are various alternative choices, some that enhance health and others that jeopardize it. Once behavioral objectives have been formulated, decisions about content should be directed toward predisposing, enabling, or reinforcing those behaviors. Emphasis should be on the following: risk reduction; recognition; response; referral; and responsible resource. No particular instructional methods possess inherent superiority. It is questionable whether young people derive a maximum benefit from STD instruction if they have not initially learned rudimentary physiological and sociological facts of sexual life and how to discuss such matters. School systems should not delay efforts to meet the 1990 goal of high quality, timely STD education for every child in the US. Guidelines for community leaders who plan education programs are listed.
