    As surgery needs have increased, the traditional surgical team has expanded to include personnel from radiology and perfusion services. A new surgical team member, the intraoperative monitoring technician, is needed to perform intraoperative monitoring during procedures that carry a higher risk of central and peripheral nerve injury. Including the intraoperative monitoring technician on the surgical team can create challenges, including surgical delays and anesthesia care considerations. When the surgical team members, including the surgeon, anesthesia care provider, and circulating nurse, understand and facilitate this new staff member's responsibilities, the technician is able to perform monitoring functions that promote the smooth flow of the surgical procedure and positive patient outcomes.

    Full Text Available Introduction: The role of scrub in the prevention of post-surgery infections is well-known. This study aimed to investigate the inputs and process of surgical scrub in operating rooms of the largest heart hospital of northwest Iran. Methods: This study took place with a before-after design as a clinical audit in 2014. A check list developed based on national and international standards of surgical hand scrub was used as the study instrument. Checklists were completed by observation of surgical team scrubbing in real situation. Descriptive statistics and graphs were used to describe the results. Results: A compliance degree with the standards for prerequisites, equipment, general items, process and time of scrub was observed as 58%, 55%, 33%, 68% and 22%, respectively. The compliance degree after the intervention was 72%, 66%, 66%, 85% and 61%, respectively. Improvement was observed in all studied aspects of scrub. The total score of compliance with the standards changed from 47% to 70%. The main issues were incorrect order of scrubbing the areas of the hands, incorrect way of scrubbing the arms, insufficient scrubbing the arms (not above elbow, and lack of awareness about hospital’s policy on scrub time. Conclusion: The results showed defects in the surgical scrub of the studied hospital and that the compliance with the standards can be improved by simple interventions. Periodical audit and observation of the scrub and then feedback is recommended.

    Though brushes are no longer used on the hands and forearms during the surgical scrub, they are still widely used on the nails. The aim of this study was to determine whether nail picks and nail brushes are effective in providing additional decontamination during a surgical hand scrub. A total of 164 operating department staff were randomised to undertake one of the following three surgical hand-scrub protocols: chlorhexidine only; chlorhexidine and a nail pick; or chlorhexidine and a nail brush. Bacterial hand sampling was conducted before and 1h after scrubbing using a modified version of the glove juice method. No statistically significant differences in bacterial numbers were found between any two of the three intervention groups. Nail brushes and nail picks used during surgical hand scrubs do not decrease bacterial numbers and are unnecessary.

    OBJECTIVE Effective perioperative hand antisepsis is crucial for the safety of patients and medical staff in surgical rooms. The antimicrobial effectiveness of different antiseptic methods, including conventional hand scrubs and waterless hand rubs, has not been well evaluated. DESIGN, SETTING, AND PARTICIPANTS A randomized controlled trial was conducted to investigate the effectiveness of the 3 antiseptic methods among surgical staff of Taipei Medical University-Shuang Ho Hospital. For each method used, a group of 80 participants was enrolled. INTERVENTION Surgical hand cleansing with conventional 10% povidone-iodine scrub, conventional 4% chlorhexidine scrub, or waterless hand rub (1% chlorhexidine gluconate and 61% ethyl alcohol). RESULTS Colony-forming unit (CFU) counts were collected using the hand imprinting method before and after disinfection and after surgery. After surgical hand disinfection, the mean CFU counts of the conventional chlorhexidine (0.5±0.2, Pantiseptic method (P=.0036), but not other variables, predicted the mean CFU count. CONCLUSIONS Conventional chlorhexidine scrub and waterless hand rub were superior to a conventional povidone-iodine product in bacterial inhibition. We recommend using conventional chlorhexidine scrub as a standard method for perioperative hand antisepsis. Waterless hand rub may be used if the higher cost is affordable.

    Full Text Available Introduction: Many post-surgical wound infections in hospitals cause morbidity and morality of patients and these are usually transmitted via hands of surgical personnel. The aim of the present study was to detect and antibiogram the bacterial agents following scrubbing of hands of surgical personnel before operation. Methods: Hands of 134 personnels of operation room were swabbed following scrubbing with antiseptic Betadine solution. Swab samples were inoculated on selective and differential media such as blood ager, McConky and manitol salt agar(MSA. Following incubation of media at 37c° for 24hr, bacterial species were identified using differential related tests. The isolated species were than antibiogramed and the results together with other data was analysed by SPSS software program. Results: Of the total of 134 cases, 81(60.4% were male and 53(39.6% female. The mean scrub time for each person was (206.1+/-103.2 seconds; 6 to 60 seconds base change. Increasing time of scrub was significantly correlated with decreasing rate of bacteria (P=0.003, (R=-0.254. Contamination was present in 129(96.3% cases following scrubbing. Maximum contamination was observed in nails (92.5%. Average number of bacteria for each individual was between 0 and 159. 62.6% of isolated bacteria were non- staphylococci and 7.7% were S. aureus. Vancomycin and ceftizoxim were the most sensitive, while penicillin was the least sensitive antibiotic. Conclusion: Results revealed that hand contamination was more than the expected standard level. Therefore, regarding the critical task of surgical personnel, training of all operation room staff is highly recommended to minimize the rate of contamination.

    MINI: Fourteen hundred consecutive patients were investigated for evaluating the utility of waterless hand rub before orthopaedic surgery. The risk in the surgical site infection incidence was the same, but costs of liquids used for hand hygiene were cheaper and the hand hygiene time was shorter for waterless protocol, compared with traditional hand scrub. A retrospective cohort study with prospectively collected data. The aim of this study was to compare SSI incidences, the cost of hand hygiene agents, and hand hygiene time between the traditional hand scrub and the waterless hand rub protocols before orthopedic surgery. Surgical site infections (SSI) prolong hospitalization and are a leading nosocomial cause of morbidity and a source of excess cost. Recently, a waterless hand rub protocol comprising alcohol based chlorhexidine gluconate for use before surgery was developed, but no studies have yet examined its utility in orthopedic surgery. Fourteen hundred consecutive patients who underwent orthopedic surgery (spine, joint replacement, hand, and trauma surgeries) in our hospital since April 1, 2012 were included. A total of 712 cases underwent following traditional hand scrub between April 1, 2012 and April 30, 2013 and 688 cases underwent following waterless hand rub between June 1, 2013 and April 30, 2014. We compared SSI incidences within all and each subcategory between two hand hygiene protocols. All patients were screened for SSI within 1 year after surgery. We compared the cost of hand hygiene agents and hand hygiene time between two groups. The SSI incidences were 1.3% (9 of 712) following the traditional protocol (2 deep and 7 superficial infections) and 1.1% (8 of 688) following the waterless protocol (all superficial infections). There were no significant differences between the two groups. The costs of liquids used for one hand hygiene were about $2 for traditional hand scrub and less than $1 for waterless hand rub. The mean hand hygiene time was 264

    Drug diversion by health care personnel poses a risk for serious patient harm. Public health identified 2 patients diagnosed with acute hepatitis C virus (HCV) infection who shared a common link with a hospital. Further investigation implicated a drug-diverting, HCV-infected surgical technician who was subsequently employed at an ambulatory surgical center. Patients at the 2 facilities were offered testing for HCV infection if they were potentially exposed. Serum from the surgical technician and patients testing positive for HCV but without evidence of infection before their surgical procedure was further tested to determine HCV genotype and quasi-species sequences. Parenteral medication handling practices at the 2 facilities were evaluated. The 2 facilities notified 5970 patients of their possible exposure to HCV, 88% of whom were tested and had results reported to the state public health departments. Eighteen patients had HCV highly related to the surgical technician's virus. The surgical technician gained unauthorized access to fentanyl owing to limitations in procedures for securing controlled substances. Public health surveillance identified an outbreak of HCV infection due to an infected health care provider engaged in diversion of injectable narcotics. The investigation highlights the value of public health surveillance in identifying HCV outbreaks and uncovering a method of drug diversion and its impacts on patients.

    Full Text Available Scrub typhus is an acute febrile illness caused by orientia tsutsugamushi, transmitted to humans by the bite of the larva of trombiculid mites. It causes a disseminated vasculitic and perivascular inflammatory lesions resulting in significant vascular leakage and end-organ injury. It affects people of all ages and even though scrub typhus in pregnancy is uncommon, it is associated with increased foetal loss, preterm delivery, and small for gestational age infants. After an incubation period of 6-21 days, onset is characterized by fever, headache, myalgia, cough, and gastrointestinal symptoms. A primary papular lesion which later crusts to form a flat black eschar, may be present. If untreated, serious complications may occur involving various organs. Laboratory studies usually reveal leukopenia, thrombocytopenia, deranged hepatic and renal function, proteinuria and reticulonodular infiltrate. Owing to the potential for severe complications, diagnosis, and decision to initiate treatment should be based on clinical suspicion and confirmed by serologic tests. A therapeutic trial of tetracycline or chloramphenicol is indicated in patients in whom the diagnosis of scrub typhus is suspected. The recommended treatment regimen for scrub typhus is doxycycline. Alternative regimens include tetracycline, chloramphenicol, azithromycin, ciprofloxacin, rifampicin, and roxithromycin. Treatment of pregnant women with azithromycin was successfully done without relapse and with favorable pregnancy outcomes. Hence, early diagnosis and treatment are essential in order to reduce the mortality and the complications associated with the disease. We searched the English-language literature for reports of scrub typhus in children, pregnant women, and non-pregnant patients with scrub typhus, using the MEDLINE/PubMed database, which includes citations from 1945 to the present time. We used the search terms ′scrub typhus′, ′scrub typhus′ and ′pregnancy′, ′scrub

CIEMAT was the Task Manager of the project and several other organizations participated in it: JRC-Ispra, NNC Limited, RUB-NES and UPM. The project was divided into several tasks. A peer review of the models in the pool scrubbing codes SPARC90 and BUSCA-AUG92 was made, considering the different aspects in the hydrodynamic phenomenology, particle retention and fission product vapor abortions. Several dominant risk accident sequences were analyzed with MAAP, SPARC90 and BUSCA-AUG92 codes, and the predictions were compared. A churn-turbulent model was developed for the hydrodynamic behaviour of the pool. Finally, an experimental programme in the PECA facility of CIEMAT was conducted in order to study the decontamination factor under jet injection regime, and the experimental observations were compared with the SPARC and BUSCA codes.

A maior dificuldade nessa elaboração deveu-se à inexistência de normas e consenso sobre a porosidade dos tecidos como barreira microbiológica e de contato com sangue e outros fluidos. Contudo, foi possível reconhecer aspectos positivos e problemáticos. Observou-se que existe semelhanças dos componentes entre os hospitais, no que se refere a modelo e tipo de tecido. As luvas foram os componentes com maior índice de adequação e os propés, os de maior índice de inadequação. O aspecto mais problemático referiu-se aos controles de aquisição e de reprocessamento dos componentes re-utilizáveis.The study elaborated evaluation patterns of the components of the surgical scrub in hospitals of the district of São Paulo. The most important difficulty was the lack of rules and consent on the types of the fabrics, as a microbiological and contact with blood and other fluids barrier. However, it was possible to identify positive and problematic aspects. It was observed that the components are similar among the hospitals, considering the design and the way of fabrics production. Gloves were the ones with the best quality results, while shootweares were the worst. The most problematic aspect was referred to the acquisition controls and the re-use process of the components.

    Full Text Available Scrub typhus is an acute febrile illness usually presenting with fever, myalgia, headache, and a pathognomonic eschar. Severe infection may lead to multiple organ failure and death. Gastrointestinal tract involvement in the form of gastric mucosal erosions and ulcerations owing to vasculitis resulting in gastrointestinal bleeding is common. This process may worsen a pre-existent asymptomatic peptic ulcer, causing duodenal perforation, and present as an acute abdomen requiring surgical exploration. We report the case of a patient with no previous symptoms or risk factors for a duodenal ulcer, who presented with an acute duodenal perforation, probably precipitated by scrub typhus infection.

    The non-technical skills of situational awareness and the formation of effective interpersonal relationships are essential to enhance surgical outcomes. However, most scrub practitioners demonstrate only tacit awareness of these skills and develop such qualities on an informal basis. Application of non-technical skills may be assessed formally, using a structured framework, to transform normative behaviour and to strengthen barriers against the latent threats that may result from fallible humans working in inadequate organisational systems.

    Scrub typhus is an acute febrile illness that, if untreated, can result in considerable morbidity and mortality. One of the primary reasons for delays in the treatment of this potentially fatal infection is the difficulty in diagnosing the condition. Diagnosis is often complicated because of the combination of non-specific symptoms that overlap with other infections commonly found in endemic areas and the poor available diagnostics. In the majority of the endemic settings, diagnosis still relies on the Weil-Felix test, which is neither sensitive nor specific. Other methods of testing have become available, but at this time, these remain insufficient to provide the rapid point-of-care diagnostics that would be necessary to significantly change the management of this infection by providers in endemic areas. This article reviews the currently available diagnostic tools for scrub typhus and their utility in the clinical setting.

    1995-12-01

    Triclosan (Irgasan), an antibacterial active against staphylococci and coliform bacteria, has been formulated for use as a handwash. There has been only one previous report of the use of the glove juice test to determine the immediate, residual, and cumulative effects of a 1% triclosan-based handwash product. There have been no previous studies on the use of 1% triclosan combined with povidone-iodine (PI) in a handwash product. The glove juice technique was used to document and compare the immediate, 3-hour residual, and 5-day cumulative effects on the mean log10 bacterial counts of 1% triclosan-based handwash product and 1% triclosan with 5% PI. A standardized surgical handwashing technique was used before sample collection. These results and the identity and type of the aerobic bacteria cultured from the samples were compared with the results of standardized washing and glove juice sampling with 4% weight/volume chlorhexidine gluconate (CHG), 7.5% PI, and a nonantimicrobial liquid soap. All five tested products showed significant log10 reduction from baseline on day 1, hour 0 (p 0.05). There was a significant difference between 1% triclosan and the liquid soap when they were each compared with 4% CHG, 7.5% PI, and 1% triclosan with 5% PI. There was no statistically significant difference between the 1% triclosan product and the liquid soap (p > 0.20). All products were effective at reducing the immediate bacterial count from the baseline level. All formulations except the liquid soap showed significant cumulative effect (p liquid soap and 1% triclosan (p > 0.05). Both products differed significantly (p < 0.05) from the CHG, PI, and triclosan with PI. CHG, PI, and triclosan with PI showed effects significantly different from each other (p < 0.05). Triclosan combined with PI resulted in the prevention of bacterial regrowth at 3 hours such as occurred when PI alone was used. Triclosan-containing products have a small cumulative effect, although not as great as that

    More than 502 million tons - 65 percent of all coal shipped to utilities in 1990 - were above 1.2 pounds of sulfur dioxide per million Btu. Most of the coal, even though cleaned in conventional coal preparation plants, still does not meet the emission limitation the Clean Air Act Amendments mandate for the year 2000. To cope with this fact, most utilities plan to switch to low sulfur (western U.S. or Central Appalachian) coal or install scrubbers. Both solutions have serous drawbacks. Switching puts local miners out of work and weakens the economy in the utility's service territory. Scrubbing requires a major capital expenditure by the utility. Scrubbers also increase the operating complexity and costs of the generating station and produce yet another environmental problem, scrubber sludge. Employing three new cost-effective technologies developed by Customer Coals International (CCl), most non-compliance coals east of the Mississippi River can be brought into year-2000 compliance. The compliance approach employed, depends upon the characteristics of the raw coal. Three types of raw coal are differentiated, based upon the amount of organic sulfur in the coals and the ease (or difficultly) of liberating the pyrite. They are: Low organic sulfur content and pyrite that liberates easily. Moderate organic sulfur content and pyrite that liberates easily. High organic sulfur content or the pyrite liberates with difficulty. In this paper examples of each type of raw coal are presented below, and the compliance approach employed for each is described. The names of the beneficiated coal products produced from each type of raw coal give above are: Carefree Coal, Self-Scrubbing Coal and Dry-Scrubbing Coal

    Scrub typhus is an emerging infection, and there is little information about status epilepticus (SE) in scrub typhus. We report the clinical spectrum and outcome of SE in scrub typhus. In a 3-year prospective hospital-based observational study, all scrub typhus patients with SE were included. Scrub typhus was diagnosed by immunochromatography assay. SE was defined if convulsions lasted longer than 5 min. The patients' demographic, clinical, computed tomography (CT), magnetic resonance imaging (MRI), and electroencephalography (EEG) findings were noted. Response to antiepileptic drugs (AEDs) and outcome at 1 month and 1 year were recorded. Between 2012 and 2014, there were 66 patients with scrub typhus admitted with central nervous system (CNS) involvement, 10 (15.2%) of whom had SE (generalized convulsions in 5, secondary generalized in one). The median age of the patients was 34 (range 18-71) years and seven were female. The duration of SE ranged between 10 min and 48 h. SE responded to one AED in five patients, two AEDs in three patients, and more than two AEDs in two patients. Cranial MRI findings were normal. All patients recovered completely with doxycycline by 1 month and AED was withdrawn by 8 months in all. Although 15% patients with scrub typhus may have SE, they have good outcome.

    The DynaWave family of scrubbers was developed and patented by DuPont in the 1970's and is used extensively within the company. Because the technology was treated as confidential, information about the scrubbers was not published outside of DuPont. In 1986 Monsanto Enviro-Chem was asked to install a Reverse Jet scrubber at DuPont's Burnside spent acid recovery pant to replace an aging spray humidifying tower. Enviro-Chem was impressed with the technology and entered into a licensing agreement with DuPont in late 1987. This paper addresses the application of DynaWave froth scrubbing technology to metallurgical plant process and effluent gas streams. Froth scrubber design principles an sampling results from pilot plant trails on fluid bed roaster off-gas are presented

    To identify and describe the factors that impact on the performance of scrub nurses' non-technical skills performance during the intra-operative phase of surgery. Non-technical skills have been identified as important precursors to errors in the operating room. However, few studies have investigated factors influencing non-technical skills of scrub nurses. Prospective observational study. Structured observations were performed on a sample of 182 surgical procedures across eight specialities by two trained observers from August 2012-April 2013 at two hospital sites. Participants were purposively selected scrub nurses. Bivariate correlations and a multiple linear regression model were used to identify associations among length of surgery, patients' acuity using the American Society of Anesthesiologists classification system, team familiarity, number of occasions scout nurses leave the operating room, change of scout nurse and the outcome, the non-technical skills performance of scrub nurses. Patient acuity and team familiarity were the strongest predictors of scrub nurses' non-technical skills performance at hospital site A. There were no correlations between the predictors and the performance of scrub nurses at hospital site B. A dedicated surgical team and patient acuity potentially influence the performance of scrub nurses' non-technical skills. Familiarity with team members foster advanced planning, thus minimizing distractions and interruptions that impact on scrub nurses' performance. Development of interventions aimed at improving non-technical skills has the potential to make a substantial difference and enhance patient care. © 2015 John Wiley & Sons Ltd.

    To evaluate high-resolution CT (HRCT) findings of scrub typhus. We retrospectively reviewed the HRCT scans of 26 serologically confirmed scrub typhus patients. One underwent follow-up HRCT scanning. Twenty-three(88.5%) of the 26 patients showed abnormal findings. All 23 had lung parenchymal lesions; a small amount of pleural effusion was seen in 11 patients, and lymphadenopathy in six. The predominant parenchymal lesion was thickening of interlobular septae and the axial and intralobular interstitium (n=16). Most lesions were located in both lower lung zones. Other findings were ground-glass attenuation (n=11) and focal parenchymal consolidation (n=8). In one patient, parenchymal lesions were resolved on follow-up HRCT scanning. HRCT findings of interstitial thickening, abnormally increased parenchymal attenuation, pleural effusion and lymphadenopathy with typical clinical symptoms were diagnostic of scrub typhus

    The mite-borne rickettsial zoonosis scrub typhus is widely prevalent in parts of Southeast and Far East Asia, and northern Australia. The disease is an acute febrile illness, associated with rash and often an eschar, which responds dramatically to treatment with antibiotics. In some cases it results in a serious illness leading to multiple organ involvement and death. The disease manifestations are thought to result from a systemic vasculitis, caused by both direct effects of the organisms as well as an exaggerated immune response, although little is understood about its pathogenesis. A wide spectrum of clinical manifestations, affecting nearly every organ system, have been described with scrub typhus. Some of these manifestations are serious and life threatening. In this systematic review, we summarise the typical and atypical manifestations of scrub typhus reported in the literature. Awareness of these unusual manifestations will hopefully guide clinicians towards diagnosing the condition early, and initiating early appropriate antibiotics and other supportive measures. © The Author 2017.

  4. Scrub Typhus: An Emerging Threat

    Science.gov (United States)

    Chakraborty, Sayantani; Sarma, Nilendu

    2017-01-01

    Scrub typhus is caused by Orientia tsutsugamushi (formerly Rickettsia) and is transmitted to humans by an arthropod vector of the Trombiculidae family (Leptotrombidium deliense and L. akamushi). It is the most common re-emerging Rickettsial infection in India and many other South East Asian countries. In fact, scrub typhus is confined geographically to the Asia Pacific region, a billion people are at risk and nearly a million cases are reported every year. Scrub typhus appears particularly to be distributed in the tsutsugamushi triangle which is distributed over a very wide area of 13 million km2 bound by Japan in the east, through China, the Philippines, tropical Australia in the south, and west through India, Pakistan, possibly to Tibet to Afghanistan, and southern parts of the USSR in the north. Eschar is the characteristic lesion that starts as a vesicular lesion at the site of mite feeding. Later, an ulcer forms with black necrotic center and an erythematous border along with regional lymphadenopathy. Other features are fever, maculopapular rash starting from the trunk, and spreading to the limbs. It may affect the central nervous system, cardiovascular system, renal, respiratory, and gastrointestinal systems. Serious complication in the form of myocarditis, pneumonia, meningoencephalitis, acute renal failure, gastrointestinal bleeding, and even acute respiratory distress syndrome may develop. Tetracycline or chloramphenicol remains the main stay of therapy. PMID:28979009

    Scrub typhus is one of the differential diagnoses for fever with thrombocytopenia. ARDS associated with Scrub typhus has high morbidity and mortality. To evaluate clinical features, lab values, and outcome in patients with scrub typhus and comparison in patients with or without ARDS. A prospective observational study was conducted on 109 patients with febrile illness and thrombocytopenia during a period of 12 months. All 109 patients were tested with both Immune-chromatography test and Weil felix test. Patients having either Immune-chromatography test/Weil felix test positive have been included and considered as scrub typhus positive whereas negative for both Immune-chromatography and Weil felix test were excluded. Clinical features, lab parameters, and outcome were evaluated in all patients with scrub typhus. Statistical analysis used in this study was T-test. Among 58 patients who were included (After exclusion of 51 patients among total of 109 patients) 34 patients had no ARDS and 24 patients had ARDS. The clinical feature like dyspnoea, cough, low blood pressure (MAPscrub typhus patients group with ARDS. The higher titers of Weil-felix can be correlated with more severe form of disease according to our observation. All 34 Scrub typhus patients without ARDS recovered completely. Among 24 Scrub typhus patients with ARDS, 22 patients recovered, and 2 patients died. Scrub typhus is an important differential diagnosis in a patients having fever with thrombocytopenia. Scrub typhus associated with ARDS has high morbidity and mortality. Early diagnosis and treatment with doxycycline can prevent the occurrence of ARDS.

    The development of an innovative role for the pharmacy technician is described. The role of the pharmacy technician was based on a needs assessment and the expertise of the pharmacy technician selected. Initial responsibilities of the technician included chart reviews, benchmarking surveys, monthly financial impact analysis, initiative assessment, and quality improvement reporting. As the drug-use and disease-state management (DUDSM) program expanded, pharmacist activities increased, requiring the expansion of data analyst technician (DAT) duties. These new responsibilities included participation in patient assessment, data collection and interpretation, and formulary enforcement. Most recently, technicians' expanded duties include maintenance of a physician compliance profiling database, quality improvement reporting and graphing, active role in patient risk assessment and database management for adult vaccination, and support of financial impact monitoring for other institutions within the health system. This pharmacist-technician collaboration resulted a threefold increase in patient assessments completed per day. In addition, as the DUDSM program continues to expand across the health system, an increase in DAT resources from 0.5 to 1.0 full-time equivalent was obtained. The role of the DAT has increased the efficiency of the DUDSM program and has provided an innovative role for the pharmacy technician.

    This paper reports on Nuclear Instrument Technician (NIT) training that has developed at an accelerated rate over the past three decades. During the 1960's commercial nuclear power plants were in their infancy. For that reason, there is little wonder that NIT training had little structure and little creditability. NIT training, in many early plants, was little more than On-The Job Training (OJT). The seventies brought changes in Instrumentation and Controls as well as emphasis on the requirements for more in depth training and documentation. As in the seventies, the eighties saw not only changes in technologies but tighter requirements, standardized training and the development of accredited Nuclear Instrument Training; thus the conclusion: Nuclear Instrument Training Isn't What It Used To Be

    To identify the factors that can predict the severity of scrub typhus in children. This prospective study was conducted at a tertiary care teaching hospital between November 2014 to October 2016. All children scrub typhus were included in the study. These children were followed during the hospital course and their laboratory results, response to treatment and complications were documented. Cases of 'severe scrub typhus' were identified based on criteria from published adult and pediatric studies. Out of 930 children with fever for more than 7d, IgM ELISA for scrub typhus was positive in 230 children. Ninety one (40.6%) cases fulfilled the criteria of 'severe scrub typhus' in children. Out of 45 factors, 27 potential factors were studied. The multivariate analysis identified 5 factors, breathlessness (OR: 6.85, 95%CI: 2.69 to 9.87), altered sensorium (OR: 11.48, 95% CI 3.43 to 10.19), leucocytosis (OR: 3.38, 95% CI 1.12 to 10.16), hypoalbuminemia (OR: 10.78, 95% CI 2.66 to 48.76), and hyponatremia (OR: 10.08, 95% CI 2.11 to 23.42) to be significantly associated with the 'severe scrub typhus' cases. Breathlessness, altered sensorium, leucocytosis, hypoalbuminemia, and hyponatremia predict severity in childhood scrub typhus. Presence of these factors should alert the treating physician regarding the need for intensive monitoring, treatment or referral.

    During the UO 2 dissolution in nitric acid, some different species of NO x are released. The off gas can either be refluxed to the dissolver or be released and retained on special columns. The final composition of the solution is the main parameter to take in account. A process for nitrous gases retention using scubber columns containing H 2 O or diluted HNO 3 is presented. Chemiluminescence measurement was employed to NO x evalution before and after scrubbing. Gas flow, temperature, residence time are the main parameters considered in this paper. For the dissolution of 100g UO 2 in 8M nitric acid, a 6NL/h O 2 flow was the best condition for the NO/NO 2 oxidation with maximum adsorption in the scrubber columns. (author) [pt

    A scrubbing nozzle is one of the key components for a wet scrubber process based Containment Filtered Venting System (CFVS). As a part of a development of Korean CFVS, a self-priming scrubbing nozzle shown in Fig. 1 has been developed based on the well-known venturi scrubber concept. The thermal-hydraulic performances such as the pressure drop across the nozzle, water suction behavior and droplet generation inside throat have been tested in the non-submerged condition as well as submerged condition. The self-priming scrubbing nozzle used for the wet scrubber based CFVS has been developed, which is submerged in the water pool. When there is gas flow at the inlet of the nozzle, the pool water is passively sucked from the water suction slit. The fine droplets generated inside the throat capture the aerosol particles and is discharged into the water pool. In the water pool, the pool scrubbing happens. The aerosol scrubbing performance tests for the developed self-priming scrubbing nozzle has been conducted under the operational conditions such as different aerosol sizes, different carrier gas steam fractions, different, different pool water level and nozzle inlet pressure. The major findings are as follows. (1) Aerosol scrubbing efficiency increases with the increase of the aerosol size. (2) Aerosol scrubbing efficiency increases with the increase of the carrier gas steam fraction. (3) Aerosol scrubbing.

This concept has been aptly used to improve understanding, training, monitoring, and reporting hand hygiene among healthcare workers. We conducted this study to assess the knowledge of doctors and health care workers regarding hand scrub. METHODS A study was conducted among doctors and health care workers in a tertiary care hospital. Knowledge was evaluated by using self-structured questionnaire based on the guidelines of hand hygiene prescribed by WHO. RESULTS The awareness and knowledge of preoperative surgical hand scrubbing was moderate in doctors, but unfortunately poor in HCWs. CONCLUSION Our study highlights the need for introducing measures in order to increase the knowledge of preoperative hand scrub in teaching hospital which may translate into good practices.

    To document the epidemiological, clinical and laboratory profile of all children with scrub typhus at a tertiary care centre in Chennai between September 2010 and June 2011. The case records of all children admitted and diagnosed with scrub typhus between September 2010 and June 2011 were analysed to look for salient clinical and laboratory parameters. During the study period, 52 children were admitted with scrub typhus in the authors' hospital. The presenting complaints included fever in all cases. Other symptoms included swelling of legs (50 %) and vomiting (45 %). 13 % presented with CNS symptoms. The commonest physical findings included eschar (67 %), hepatomegaly (94 %), splenomegaly (73 %) and third spacing (67 %). Salient lab parameters included packed cell volume (PCV) scrub typhus in a tertiary care centre is reported. Eschar and hepatosplenomegaly with a high CRP value is helpful in diagnosis. All patients responded well to the treatment.

    Adverse events still occur despite ongoing efforts to reduce harm to patients. Contributory factors to adverse events are often due to limitations in clinicians' non-technical skills (e.g. communication, situation awareness), rather than deficiencies in technical competence. We developed a behavioural rating system to provide a structured means for teaching and assessing scrub practitioners' (i.e. nurse, technician, operating department practitioner) non-technical skills. Psychologists facilitated focus groups (n = 4) with experienced scrub practitioners (n = 16; 4 in each group) to develop a preliminary taxonomy. Focus groups reviewed lists of non-technical-skill-related behaviours that were extracted from an interview study. The focus groups labelled skill categories and elements and also provided examples of good and poor behaviours for those skills. An expert panel (n = 2 psychologists; n = 1 expert nurse) then used an iterative process to individually and collaboratively review and refine those data to produce a prototype skills taxonomy. A preliminary taxonomy containing eight non-technical skill categories with 28 underlying elements was produced. The expert panel reduced this to three categories (situation awareness, communication and teamwork, task management), each with three underlying elements. The system was called the Scrub Practitioners' List of Intraoperative Non-Technical Skills system. A scoring system and a user handbook were also developed. A prototype behavioural rating system for scrub practitioners' non-technical skills was developed, to aid in teaching and providing formative assessment. This important aspect of performance is not currently explicitly addressed in any educational route to qualify as a scrub practitioner. © 2012 Blackwell Publishing Ltd.

    Ambiguity remains about the effectiveness of wearing surgical face masks. The purpose of this study was to assess the impact on surgical site infections (SSIs) when non-scrubbed operating room staff did not wear surgical face masks. Eight hundred twenty-seven participants undergoing elective or emergency obstetric, gynecological, general, orthopaedic, breast or urological surgery in an Australian tertiary hospital were enrolled. Complete follow-up data were available for 811 patients (98.1%). Operating room lists were randomly allocated to a 'Mask group' (all non-scrubbed staff wore a mask) or 'No Mask group' (none of the non-scrubbed staff wore masks). The primary end point, SSI was identified using in-patient surveillance; post discharge follow-up and chart reviews. The patient was followed for up to six weeks. Overall, 83 (10.2%) surgical site infections were recorded; 46/401 (11.5%) in the Masked group and 37/410 (9.0%) in the No Mask group; odds ratio (OR) 0.77 (95% confidence interval (CI) 0.49 to 1.21), p = 0.151. Independent risk factors for surgical site infection included: any pre-operative stay (adjusted odds ratio [aOR], 0.43 (95% CI, 0.20; 0.95), high BMI aOR, 0.38 (95% CI, 0.17; 0.87), and any previous surgical site infection aOR, 0.40 (95% CI, 0.17; 0.89). Surgical site infection rates did not increase when non-scrubbed operating room personnel did not wear a face mask.

    Scrub typhus is an acute and febrile infectious disease caused by the Gram-negative α-proteobacterium Orientia tsutsugamushi from the family Rickettsiaceae that is widely distributed in Northern, Southern and Eastern Asia. In the present study, we analysed the serum proteome of scrub typhus patients to investigate specific clinical protein patterns in an attempt to explain pathophysiology and discover potential biomarkers of infection. Serum samples were collected from three patients (before and after treatment with antibiotics) and three healthy subjects. One-dimensional sodium dodecyl sulphate-polyacrylamide gel electrophoresis followed by liquid chromatography-tandem mass spectrometry was performed to identify differentially abundant proteins using quantitative proteomic approaches. Bioinformatic analysis was then performed using Ingenuity Pathway Analysis. Proteomic analysis identified 236 serum proteins, of which 32 were differentially expressed in normal subjects, naive scrub typhus patients and patients treated with antibiotics. Comparative bioinformatic analysis of the identified proteins revealed up-regulation of proteins involved in immune responses, especially complement system, following infection with O. tsutsugamushi , and normal expression was largely rescued by antibiotic treatment. This is the first proteomic study of clinical serum samples from scrub typhus patients. Proteomic analysis identified changes in protein expression upon infection with O. tsutsugamushi and following antibiotic treatment. Our results provide valuable information for further investigation of scrub typhus therapy and diagnosis.

    Identifying an eschar in scrub typhus is useful for initiation of prompt and appropriate antibiotic therapy. The distribution of eschars in all children scrub typhus over a 5 year period is described. Of 431 children admitted with scrub typhus, eschars were present in 176 (40.8%) children with the following distribution: head, face and neck, 33 (19.1%); axillae, 37 (21%); chest and abdomen, 21 (11.9%); genitalia, inguinal region and buttocks, 58 (33%); back, 8 (4.5%); upper extremities, 13 (7.4%); and lower extremities, 5 (2.8%). The commonest sites of eschars were scrotum (27 of 106; 25.5%) and axillae (15 of 106; 14.2%) in males and axillae (22 of 70; 31.4%) and groin (16 of 70; 22.9%) in females. Eschars were seen within skin folds in 100 of 176 (56.8%) children. Children should be carefully examined for the presence of eschar especially in the skin folds of the genitalia, axillae and groin to make an early diagnosis of scrub typhus. © The Author [2016].

    Full Text Available Scrub typhus is endemic in large parts of India and can cause multi-organ failure and death. Acute pancreatitis as a complication is very rare and is potentially fatal. This case series describes seven adult patients who presented with an acute febrile illness and were diagnosed to have scrub typhus with acute pancreatitis. The mean age of the seven patients with acute pancreatitis was 49.4 years, and mean duration of fever prior to presentation was 7.7 days. All seven patients had abdominal pain, and three had a pathognomonic eschar. The mean serum lipase level was 1,509 U/L (normal value: <190 U/L and the mean serum amylase level was 434 U/L (normal value: <200 U/L. Six patients had evidence of multi-organ dysfunction. Hematological and respiratory system dysfunction was seen in five patients, hepatic and renal dysfunction in four, and central nervous system dysfunction in three patients. Three patients who had ≥4 organs involved, died (mortality rate: 42.8%. Our case series shows that pancreatitis in scrub typhus is an extremely rare complication and when present, is associated with increased mortality (42.8%. Physicians may be familiar with the various complications of scrub typhus but less so with acute pancreatitis and hence may be underdiagnosed.

  16. Pool scrubbing models for iodine components

    1996-12-01

    Pool scrubbing is an important mechanism to retain radioactive fission products from being carried into the containment atmosphere or into the secondary piping system. A number of models and computer codes has been developed to predict the retention of aerosols and fission product vapours that are released from the core and injected into water pools of BWR and PWR type reactors during severe accidents. Important codes in this field are BUSCA, SPARC and SUPRA. The present paper summarizes the models for scrubbing of gaseous Iodine components in these codes, discusses the experimental validation, and gives an assessment of the state of knowledge reached and the open questions which persist. The retention of gaseous Iodine components is modelled by the various codes in a very heterogeneous manner. Differences show up in the chemical species considered, the treatment of mass transfer boundary layers on the gaseous and liquid sides, the gas-liquid interface geometry, calculation of equilibrium concentrations and numerical procedures. Especially important is the determination of the pool water pH value. This value is affected by basic aerosols deposited in the water, e.g. Cesium and Rubidium compounds. A consistent model requires a mass balance of these compounds in the pool, thus effectively coupling the pool scrubbing phenomena of aerosols and gaseous Iodine species. Since the water pool conditions are also affected by drainage flow of condensate water from different regions in the containment, and desorption of dissolved gases on the pool surface is determined by the gas concentrations above the pool, some basic limitations of specialized pool scrubbing codes are given. The paper draws conclusions about the necessity of coupling between containment thermal-hydraulics and pool scrubbing models, and proposes ways of further simulation model development in order to improve source term predictions.

    Wet scrubbing systems are the most versatile and cost efficient of all air pollution abatement technologies. This paper presented System REITHER{sup TM} which is a new generation of venturi scrubber. The advantages of this design are that it is simple and compact, has high removal efficiencies for sub-micron dusts or aerosols and it is flexible to handle any mass flow rate. It also provides high and constant reliability, is easy to control and has the potential to absorb gaseous pollutants. Another advantage is that it can handle corrosive streams through corrosion resistant materials. Innovations in wet scrubbing have made it possible to provide reliable and efficient separation of fine particles, corrosive aerosols and gases. New technology provides industrial engineers with a cost effective option when control air emissions is required. 1 fig.

    To evaluate the effectiveness of an immunization training program for pharmacy technicians on technicians' self-reported confidence, knowledge, and number of vaccines administered. A one-group pre- and posttest study was conducted with certified pharmacy technicians from Albertsons and Safeway community pharmacies in Idaho. Thirty pharmacy technicians were recruited to participate in an immunization administration training program comprising a 2-hour home study and a 2-hour live training. Pharmacy technician scores on a 10-question knowledge assessment, responses on a pre- and posttraining survey, and number of immunizations administered in the 6-month period following the training were collected. Twenty-five pharmacy technicians completed the home study and live portions of the immunization training program. All 29 pharmacy technicians who took the home study assessment passed with greater than 70% competency on the first attempt. Technicians self-reported increased confidence with immunization skills between the pretraining survey and the posttraining survey. From December 2016 to May 2017, the technicians administered 953 immunizations with 0 adverse events reported. For the first time, pharmacy technicians have legally administered immunizations in the United States. Trained pharmacy technicians demonstrated knowledge of vaccination procedures and self-reported improved confidence in immunization skills and administered immunizations after participating in a 4-hour training program.

    Respiratory system involvement in scrub typhus is seen in 20-72% of patients. In endemic areas, good understanding and familiarity with the various radiologic findings of scrub typhus are essential in identifying pulmonary complications. Patients admitted to a tertiary care center with scrub typhus between October 2012 and September 2013 and had a chest X ray done were included in the analysis. Details and radiographic findings were noted and factors associated with abnormal X-rays were analyzed. The study cohort contained 398 patients. Common presenting complaints included fever (100%), generalized myalgia (83%), headache (65%), dyspnea (54%), cough (24.3%), and altered sensorium (14%). Almost half of the patients (49.4%) had normal chest radiographs. Common radiological pulmonary abnormalities included pleural effusion (14.6%), acute respiratory distress syndrome (14%), airspace opacity (10.5%), reticulonodular opacities (10.3%), peribronchial thickening (5.8%), and pulmonary edema (2%). Cardiomegaly was noted in 3.5% of patients. Breathlessness, presence of an eschar, platelet counts of 2 mg/dL had the highest odds of having an abnormal chest radiograph. Patients with an abnormal chest X-ray had a higher requirement of noninvasive ventilation (odds ratio [OR]: 13.98; 95% confidence interval CI: 5.89-33.16), invasive ventilation (OR: 18.07; 95% CI: 6.42-50.88), inotropes (OR: 8.76; 95% CI: 4.35-17.62), higher involvement of other organ systems, longer duration of hospital stay (3.18 ± 3 vs. 7.27 ± 5.58 days; Pscrub typhus have abnormal chest radiographs. Chest radiography should be included as part of basic evaluation at presentation in patients with scrub typhus, especially in those with breathlessness, eschar, jaundice, and severe thrombocytopenia.

  5. Simulation of pool scrubbing experiments using BUSCA

    International Nuclear Information System (INIS)

    Dehbi, A.; Guentay, S.

    1994-01-01

    BUSCA-PSI is a computer code which predicts the aerosol scrubbing taking place when gas bubbles containing fission products rise through stagnant pools of water after a postulated severe accident. A Lagrangian formulation is adopted to follow the path of a bubble as it rises toward the surface of the pool. The BUSCA model includes most aerosol removal mechanisms which are thought to be significant, namely: Jet Impaction at tile orifice, Convection/Diffusiophoresis during steam condensation, Thermophoresis, Sedimentation, Centrifugal Impaction during bubble rise, and Brownian Diffusion. The hydraulic modelling offers a variety of options for the initial globule volume, the stable bubble size, tile bubble rise velocity, and the bubble shape. The heat and mass transfer part of tile model uses correlations found in the relevant literature. BUSCA simulations were performed to determine the decontamination factor (DF) dependence on key aerosol and thermal hydraulic parameters. The decontamination factor increases with height, pool temperature subcooling, and steam content. The decontamination factor exhibits a parabolic dependence on the particle radius. At low particle sizes, the DF is high due to Brownian Diffusion which is the dominant removal mechanism. The DF hits a minimum and then increases with particle size as Centrifugal Impaction and Sedimentation become important. In separate calculations, BUSCA was used to the simulate the aerosol scrubbing experiments performed by EPRI. For cold pool tests, the predicted scrubbing efficiencies were in a good, conservative agreement with the data for both Tin and CsI, and the discrepancies were within the reported measurement errors. For hot pool tests, the code systematically underpredicted the scrubbing DF's; this is potentially due to condensation in the gas space above the pool, a situation not currently modelled by BUSCA. The code was also tested against data produced by the Tepco-Toshiba-Hitachi experiments. The

    The objective of this project to develop an advanced flue gas desulfurization (FGD) process that has decreased capital and operating costs, higher SO 2 removal efficiency, and better by-product solids quality than existing, commercially available technology. A clear liquor process (which uses a scrubbing liquid with no solids) will be used to accomplish this objective rather than a slurry liquor process (which contains solids). This clear liquor scrubbing (CLS) project is focused on three research areas: (1) Development of a clear liquor scrubbing process that uses a clear solution to remove SO 2 from flue gas and can be operated under inhibited-oxidation conditions; (2) Development of an anhydrite process that converts precipitated calcium sulfite to anhydrous calcium sulfate (anhydrite); and (3) Development of an alkali/humidification process to remove HCl from flue gas upstream of the FGD system. The anhydrite process also can be retrofit into existing FGD systems to produce a valuable by-product as an alternative to gypsum. This fits well into another of FETC's PRDA objectives of developing an advanced byproduct recovery subsystem capable of transforming SO 2 into a useable byproduct or high-volume valuable commodities of interest. This paper describes the proposed processes, outlines the test approach, and preliminary Phase I test results

Surgeons, scrub nurses, and dental technicians participating in 50 surgical and 50 dental procedures. We collected 679 latex surgical gloves after surgical procedures and tested them for patency by using a water pressure test. We also employed an electronic glove leak detector before donning, after sequential time intervals, and upon termination of 47 surgical (sequential surgical), 50 dental (sequential dental), and in three orthopedic cases where double gloving was used. The electronic glove leak detector was validated by using electronic point-by-point surface probing, fluorescein dye diffusion, as well as detecting glove punctures made with a 27-gauge needle. The random study indicated a leak rate of 33.0% (224 out of 679) in latex surgical gloves; the sequential surgical study demonstrated patency in 203 out of 347 gloves (58.5%); the sequential dental study showed 34 leaks in the 106 gloves used (32.1%); and with double gloving, the leak rate decreased to 25.0% (13 of 52 gloves tested). While the allowable FDA defect rate for unused latex surgical gloves is 1.5%, we noted defect rates in unused gloves of 5.5% in the sequential surgical, 1.9% in the sequential dental, and 4.0% in our electronic glove leak detector validating study. In the sequential surgical study, 52% of the leaks had occurred by 75 mins, and in the sequential dental study, 75% of the leaks

    To determine the influence of age, year of graduation, and video game experience on baseline laparoscopic psychomotor skills. Cross-sectional. Licensed veterinarians (n = 38) and registered veterinary technicians (VTs) (n = 49). A laparoscopic box trainer was set up at the 2016 Ontario Veterinary Medical Association (OVMA) and the 2016 Ontario Association of Veterinary Technicians (OAVT) conferences held in Toronto, Ontario, Canada. Participants volunteered to perform a single repetition of a peg transfer (PT) exercise. Participants were given a short demonstration of the PT task prior to testing. A Spearman's rank correlation (r s ) was used to identify associations between baseline psychomotor skills and self-reported surgical and non-surgical experiences collected via survey. Mann-Whitney U tests were used to compare PT scores in veterinarians and VTs. A P-value of  .05). Veterinary technicians that frequently used chopsticks scored higher than those without chopstick experience (P = .04). Age and year of graduation correlated inversely, while self-reported VG experience correlated positively with laparoscopic psychomotor skills of veterinarians, when assessed on a simulator. The use of chopsticks may contribute to the acquisition of psychomotor skills in VTs. © 2017 The American College of Veterinary Surgeons.

    Full Text Available Background and Rationale: Respiratory system involvement in scrub typhus is seen in 20–72% of patients. In endemic areas, good understanding and familiarity with the various radiologic findings of scrub typhus are essential in identifying pulmonary complications. Materials and Methods: Patients admitted to a tertiary care center with scrub typhus between October 2012 and September 2013 and had a chest X ray done were included in the analysis. Details and radiographic findings were noted and factors associated with abnormal X-rays were analyzed. Results: The study cohort contained 398 patients. Common presenting complaints included fever (100%, generalized myalgia (83%, headache (65%, dyspnea (54%, cough (24.3%, and altered sensorium (14%. Almost half of the patients (49.4% had normal chest radiographs. Common radiological pulmonary abnormalities included pleural effusion (14.6%, acute respiratory distress syndrome (14%, airspace opacity (10.5%, reticulonodular opacities (10.3%, peribronchial thickening (5.8%, and pulmonary edema (2%. Cardiomegaly was noted in 3.5% of patients. Breathlessness, presence of an eschar, platelet counts of 2 mg/dL had the highest odds of having an abnormal chest radiograph. Patients with an abnormal chest X-ray had a higher requirement of noninvasive ventilation (odds ratio [OR]: 13.98; 95% confidence interval CI: 5.89–33.16, invasive ventilation (OR: 18.07; 95% CI: 6.42–50.88, inotropes (OR: 8.76; 95% CI: 4.35–17.62, higher involvement of other organ systems, longer duration of hospital stay (3.18 ± 3 vs. 7.27 ± 5.58 days; P< 0.001, and higher mortality (OR: 4.63; 95% CI: 1.54–13.85. Conclusion: Almost half of the patients with scrub typhus have abnormal chest radiographs. Chest radiography should be included as part of basic evaluation at presentation in patients with scrub typhus, especially in those with breathlessness, eschar, jaundice, and severe thrombocytopenia.

    Central nervous system (CNS) involvement of scrub typhus infection is well known. Most CNS involvement of scrub typhus infection present as meningitis or encephalitis. We report on a patient suffering from hemorrhagic transformation of intracranial lesions caused by Orientia tsutsugamushi. A 53-year-old female farmer who was infected by scrub typhus was treated with doxycycline and recovered from the systemic illness. However, headache persisted. Brain radiologic studies revealed acute intracranial hemorrhage and enhancing lesion, which implied a CNS involvement. Hemorrhagic transformation of encephalitis by scrub typhus is very rare complication and to our best knowledge, this is the first report of hemorrhagic transformation of scrub typhus encephalitis. Clinician should consider the possibility of hemorrhagic transformation of encephalitis in cases of scrub typhus infection.

    Full Text Available Renal failure caused by scrub typhus is known to be reversible. In most cases, renal function is almost fully restored after appropriate antibiotic treatment. A 71-year-old man was diagnosed with scrub typhus complicated by renal failure. A renal biopsy revealed histopathologic findings consistent with acute tubulointerstitial nephritis. Renal function did not improve 18 months after discharge and the patient required continuous hemodialysis. Although severe renal failure requiring dialysis is a rare complication of scrub typhus, we describe a case of scrub typhus requiring maintenance hemodialysis. To the best of our knowledge, this is the first such report.

    Scrub typhus is the most common febrile disease in Korea during the autumn. Jeju Island is the largest island in South Korea and has a distinctive oceanic climate. This study aimed to identify epidemiologic characteristics of scrub typhus on Jeju Island. From January 2011 to December 2016, 446 patients were diagnosed with scrub typhus on Jeju Island. The patients' personal data and the environmental factors that might be related to scrub typhus were investigated and retrospectively analyzed. The median age of the patients was 58-years-old (range, 8 to 91) and 43% of them worked in the agricultural, forestry or livestock industry. Regardless of their job, 87% of the patients had a history of either working outdoors or of other activities before developing scrub typhus. The south and southeast regions of Jeju Island, especially Namwon-eup, showed the highest incidence of scrub typhus. Workers in mandarin orange orchards seemed to be the highest risk group for scrub typhus infection. Scrub typhus on Jeju Island showed unique characteristics. To efficiently prevent scrub typhus, each year individual regional approaches should be developed based on the epidemiologic characteristics of the disease.

    The technician has a responsible role to fulfil in nuclear industry, acting as a bridge between the engineer and the skilled worker. Technicians must have sufficient theoretical knowledge to communicate with engineers, and a thorough understanding of technological practice; the nuclear industry demands both theory and practice of a high standard. In Brazil the essential role of the technician in industry is in general recognized. However, the lack of a nationally recognized Nuclear Technician and Nuclear Technologist qualification, as well as a desire of the best technicians to quality as engineers and, in some areas, inadequate salaries has resulted in a shortage of well-trained technicians. A first step to ensure availability of these technicians is to improve their career prospects and status through definition of appropriate career standards and salaries. Practical training by the industry can only be given in factories, plants and construction sites where nuclear work is done. It is proposed to extend apprentice training centres at three sites, to give the most promising students after two years of apprentice training two further years of instruction and practice to qualify as Nuclear Technicians. The training centres are chosen to cover the three sectors of nuclear industry where special training of technicians is important: manufacture and construction; operation and maintenance; and testing and analysis for process control and safety.

    Full Text Available Background: Dengue and scrub typhus share similar clinical and epidemiological features, and are difficult to differentiate at initial presentation. Many places are endemic to both these infections where they comprise the majority of acute undifferentiated febrile illnesses. Materials and Methods: We aimed to develop a score that can differentiate scrub typhus from dengue. In this cross-sectional study, 188 cases of scrub typhus and 201 cases of dengue infection who presented to the emergency department or medicine outpatient clinic from September 2012 to April 2013 were included. Univariate followed by multivariate logistic regression analysis was performed to identify clinical features and laboratory results that were significantly different between the two groups. Each variable was assigned scores based on the strength of association and receiver operating characteristics area under the curve (ROC-AUC was generated and compared. Six scoring models were explored to ascertain the model with the best fit. Results: Model 2 was developed using the following six variables: oxygen saturation (>90%, ≤90%, total white blood cell count (7000 cells/cumm, hemoglobin (≤14 and >14 g/dL, total bilirubin (200 and ≥200 IU/dL, and altered sensorium (present or absent. Each variable was assigned scores based on its strength of association. The AUC-ROC curve (95% confidence interval for model 2 was 0.84 (0.79–0.89. At the cut off score of 13, the sensitivity and specificity were 85% and 77% respectively, with a higher score favoring dengue. Conclusion: In areas of high burden of ST and dengue, model 2 (the “clinical score to differentiate scrub typhus and dengue fever” is a simple and rapid clinical scoring system that may be used to differentiate scrub typhus and dengue at initial presentation.

    Schultz, Daniel Clyde

    Commercial aviation and commercial space similarly launch, fly, and land passenger vehicles. Unlike aviation, the U.S. government has not established maintenance policies for commercial space. This study conducted a mixed methods review of 610 U.S. space launches from 1984 through 2011, which included 31 failures. An analysis of the failure causal factors showed that human error accounted for 76% of those failures, which included workmanship error accounting for 29% of the failures. With the imminent future of commercial space travel, the increased potential for the loss of human life demands that changes be made to the standardized procedures, training, and certification to reduce human error and failure rates. Several recommendations were made by this study to the FAA's Office of Commercial Space Transportation, space launch vehicle operators, and maintenance technician schools in an effort to increase the safety of the space transportation passengers.

  18. Geochemical modeling of magmatic gas scrubbing

    Full Text Available The EQ3/6 software package, version 7.2 was successfully used to model scrubbing of magmatic gas by pure water at 0.1 MPa, in the liquid and liquid-plus-gas regions. Some post-calculations were necessary to account for gas separation effects. In these post-calculations, redox potential was considered to be fixed by precipitation of crystalline a-sulfur, a ubiquitous and precocious process. As geochemical modeling is constrained by conservation of enthalpy upon water-gas mixing, the enthalpies of the gas species of interest were reviewed, adopting as reference state the liquid phase at the triple point. Our results confirm that significant emissions of highly acidic gas species (SO2(g, HCl(g, and HF(g are prevented by scrubbing, until dry conditions are established, at least locally. Nevertheless important outgassing of HCl(g can take place from acid, HCl-rich brines. Moreover, these findings support the rule of thumb which is generally used to distinguish SO2-, HCl-, and HF-bearing magmatic gases from SO2-, HCl-, and HF-free hydrothermal gases.

    Under the 1990 Clean Air Act Amendments (CAAA), scrubbing and emission allowance trading will play complementary roles. This paper reviews Phase I announced strategies and presents projections of technology controls, coal switching and industry-wide SO 2 removal costs under different assumptions about trading. The principal uncertainties characterizing today's planning environment are discussed -- ranging from changing expectations for fuel costs to swings in allowance prices and questions about regulation and new operating procedures. Economic forecasting is difficult. A clearer picture of Phase 2 strategies is emerging from EPRI's integrated analysis of fuel, technology and allowance markets -- based on collaboration between A. Van Horn and K. White (management consultants) and T. Hewson (Energy Ventures Analysis). About half the SO 2 reductions required in Phase 2 are likely to come from technology controls and half from coal switching. With trading, the highest cost open-quotes scrubsclose quotes and open-quotes switchesclose quotes can be avoided, more upgrading of low-cost scrubbing is expected, and the role of switching grows to a small extent. Additional benefits from trading, averaging and banking allowances are: better sequencing of technology controls, less stringent specs for equipment, and added flexibility/risk-sharing opportunities in contract arrangements

    Eschar in scrub typhus aids in early diagnosis and institution of appropriate therapy; however, the eschar positivity rates vary greatly in endemic regions. Multiple eschars in scrub typhus are a rare presentation. Our patient presented with fever and multiple eschars and was empirically started on doxycycline. Nested polymerase chain reaction from all the four eschars and from EDTA blood were positive for 56-kDa type-specific antigen which is specific for Orientia tsutsugamushi The patient recovered completely after 7 days of antibiotic treatment. He was from an area where scrub typhus was not observed previously. An eschar in an acute febrile patient from the "tsutsugamushi triangle" is a valuable sign in scrub typhus diagnosis. A search for multiple eschars in scrub typhus must be made by clinicians. © The Author(s) 2016.

    Since its recurrence in 1986, scrub typhus has been occurring annually and it is considered as one of the most prevalent diseases in Korea. Scrub typhus is a 3rd grade nationally notifiable disease that has greatly increased in Korea since 2000. The objective of this study is to construct a disease incidence model for prediction and quantification of the incidences of scrub typhus. Using data from 2001 to 2010, the incidence Artificial Neural Network (ANN) model, which considers the time-lag between scrub typhus and minimum temperature, precipitation and average wind speed based on the Granger causality and spectral analysis, is constructed and tested for 2011 to 2012. Results show reliable simulation of scrub typhus incidences with selected predictors, and indicate that the seasonality in meteorological data should be considered.

    This retrospective study aimed to evaluate the levels of coagulation factors and presence of disseminated intravascular coagulation (DIC) in patients with scrub typhus. We included patients confirmed to have scrub typhus at the Chosun University Hospital between September 2004 and December 2009. The DIC scores were evaluated in 365 patients and 36 healthy controls. The median concentrations of fibrinogen, d-dimer, and fibrin/fibrinogen degradation products (FDP) were compared between patients and healthy controls (pscrub typhus had longer prothrombin time and lower platelet counts than the controls. Major bleeding was observed in 18/365 patients with scrub typhus. Fifty-one (14.0%) patients presented with severe complications of scrub typhus. Overt DIC and thrombocytopenia (scrub typhus had overt DIC, as defined by the International Society on Thrombosis and Hemostasis DIC score (DIC1) and the DIC-scoring template with a fibrinogen/C-reactive protein-ratio (DIC2), respectively. Three (16.7%) and 10 (55.6%) patients with bleeding had overt DIC, as defined by the DIC1 and DIC2, respectively. Seven (13.7%) and 26 (51%) patients with severe illness had overt DIC, as defined by DIC1 and DIC2, respectively. In conclusion, activation of the coagulation system is an important feature of scrub typhus and is correlated with severe disease, including bleeding. This is the first study to report a relationship between DIC and scrub typhus. Copyright © 2017 Elsevier Inc. All rights reserved.

    Scrub typhus is a major reason for febrile illness, caused by a bacterium Orientia tsutsugamushi, a rickettsial pathogen. Few outbreaks of scrub typhus have been reported from Arunachal Pradesh in recent past. However, there is lack of seroprevalence data from the region. In this regard, this study was undertaken using archival serum sample available from seven districts of Arunachal Pradesh. This serological study was conducted in Regional Medical Research Center for NE Region, Dibrugarh. Reactivity to IgG class of antibodies against scrub typhus was done using Scrub typhus detect IgG ELISA kit as per manufacturer's protocol. Seroprevalence of scrub typhus in seven districts of Arunachal Pradesh was found to be 40% (120/300). The age-specific scrub typhus seroprevalence rose steadily from 5.6% in children scrub typhus infection should be considered in differential diagnosis of any acute febrile illness in this part of the country. In view of the high prevalence, empirical therapy of doxycycline/azithromycin may be done in cases of undiagnosed fever. Active surveillance has to be done to understand exact magnitude, epidemiological aspects, and distribution of vector and disease of this reemerging neglected tropical disease.

  8. Estimated effects of interfacial vaporization on fission product scrubbing

    International Nuclear Information System (INIS)

    Moody, F.J.; Nagy, S.G.

    1983-01-01

    When bubbles containing non-condensible gas rise through a water pool, interfacial evaporation causes a flow of vapor into the bubbles. The inflow reduces the outward particle motion toward the bubble wall, diminishing the effectiveness of fission product particle removal. This analysis provides an estimate of evaporation on pool scrubbing effectiveness. It is shown that hot gas, which boils water at the bubble wall, reduces the effective scrubbing height by less than five centimeters. Although the evaporative humidification in a rising bubble containing non-condensible gas has a diminishing effect on scrubbing mechanisms, substantial decontamination is still expected even for the limiting case of a saturated pool

    Among the Japanese radiological technicians, four deaths from aplastic anemia have been reported after 1930. On the other hand, during the period from 1930 to 1960, the population of radiological technicians is estimated to be 74,400 man-years, in which 0.5 aplastic anemias are expected. However, actually three died from aplastic anemia. This difference is statistically significant at the 1% level. While, in the period from 1961 to 1973, the observed value is 1 against 0.7 expected. It is concluded that aplastic anemia had been induced frequently among the Japanese radiological technicians in the era when there was much exposure to occupational radiation. (orig.) [de

    Scrub typhus is a serious public health problem in the Asia-Pacific area. It threatens one billion people globally, and causes illness in one million people each year. Caused by Orientia tsutsugamushi, scrub typhus can result in severe multiorgan failure with a case fatality rate up to 70% without appropriate treatment. The antigenic heterogeneity of O. tsutsugamushi precludes generic immunity and allows reinfection. As a neglected disease, there is still a large gap in our knowledge of the disease, as evidenced by the sporadic epidemiologic data and other related public health information regarding scrub typhus in its endemic areas. Our objective is to provide a systematic analysis of current epidemiology, prevention and control of scrub typhus in its long-standing endemic areas and recently recognized foci of infection.

    The scrubber tank is filled with scrubbing water with the chemical additives. The droplet separator based on a cyclone is installed above the scrubbing water pool to remove the large droplets that may clog a metal fiber filter installed at the upper section of the scrubber tank. The outlet piping is connected from the scrubber tank to the molecular sieve to chemically remove the gaseous iodine. The aerosol as a particle is physically captured in the scrubbing water pool passing through the scrubbing nozzle as well as the metal fiber filter. The gaseous iodine such as molecular iodine as well as organic iodide is chemically removed in the scrubbing water pool and molecular sieve.

    The scrubber tank is filled with scrubbing water with the chemical additives. The droplet separator based on a cyclone is installed above the scrubbing water pool to remove the large droplets that may clog a metal fiber filter installed at the upper section of the scrubber tank. The outlet piping is connected from the scrubber tank to the molecular sieve to chemically remove the gaseous iodine. The aerosol as a particle is physically captured in the scrubbing water pool passing through the scrubbing nozzle as well as the metal fiber filter. The gaseous iodine such as molecular iodine as well as organic iodide is chemically removed in the scrubbing water pool and molecular sieve. The thermal-hydraulic as well as scrubbing performance for the CFVS should be verified with the experiments.

    Radioactive iodines can be recovered from a nitric acid scrub solution containing mercuric nitrate by passing a current through the scrub solution to react the iodine with the mercuric nitrate to form mercuric iodate which precipitates out. The mercuric iodate can then be reacted to recover the radioiodine for further processing into a form suitable for long-term storage and to recover the mercury for recycling.

    This trial was designed to compare the efficacy of 4% chlorhexidine gluconate (CHG) with normal saline (NS) as a predisinfection skin-scrub solution prior to standard presurgical skin preparation. Data was collected at a single transplantation center where patients electing resection of hepatic tumors were recruited between October 2011 and September 2012. In total, 100 patients were consecutively enrolled for random assignment to either 4% CHG or NS as a predisinfection skin-scrub solution prior to surgery. Our aim was to assess the comparative antiseptic efficacy of CHG in this setting, focusing on cutaneous microbial colonization (at baseline, preoperatively, and postoperatively) and postsurgical site infections as primary outcome measures. Positivity rates of baseline, preoperative, and postoperative cultures were similar for both groups, showing significant declines (relative to baseline) after skin preparation and no significant postsurgical rebound. Rates of surgical site infection were also similar in both groups (CHG, 6.0%; NS, 4.1%; P = 1.0). For patients with hepatic tumors undergoing hepatectomy, the effect of 4% CHG as a predisinfection scrub solution was similar to that of NS in terms of skin decontamination and surgical site infections.

    Scrub typhus is a neglected tropical disease and is under reported from Nepal. The objective of this study was to investigate the sero-epidemiology of scrub typhus in patients suffering from acute febrile illness. A total of 434 specimens collected from July to November 2015 at National Public Health Laboratory (NPHL) were investigated for detection of immunoglobulin M (IgM) antibody to Orientiatsutsugamushi.The Scrub Typhus Detect TM kit (InBios, USA) was used to detect the antibodies to O.tsutsugamushi in human serum. Randomly selected 10% positive specimens were used for confirmation by dot- enzyme-linked immunosorbent assay and indirect immunofluorescence assay. Of the total, 175 (40.3%) were positive for IgM antibodies to O. tsutsugamushi. Positive results of scrub typhus were highest among female in 11-20 year followed by males in 41-50 years age group. The IgM antibodies to O. tsutusugamushi were positive in specimens of various geographical regions including 30 districts of Nepal. Positive cases were found in various ecological regions of Nepal. Scrub typhus is one of the neglected tropical diseases in Nepal. Patients with acute febrile illness should be investigated for scrub typhus with high priority. There is an urgent need of reliable and affordable diagnostic tests at all level of health facilities of Nepal. Surveillance and public health awareness about the disease transmission and preventive measures needs to be initiated.

    Florida scrub-jays Aphelocoma coerulescens are listed as threatened under the Endangered Species Act due to loss and degradation of scrub habitat. This study concerned the development of an optimal strategy for the restoration and management of scrub habitat at Merritt Island National Wildlife Refuge, which contains one of the few remaining large populations of scrub-jays in Florida. There are documented differences in the reproductive and survival rates of scrubjays among discrete classes of scrub height (Markov models to estimate annual transition probabilities among the four scrub-height classes under three possible management actions: scrub restoration (mechanical cutting followed by burning), a prescribed burn, or no intervention. A strategy prescribing the optimal management action for management units exhibiting different proportions of scrub-height classes was derived using dynamic programming. Scrub restoration was the optimal management action only in units dominated by mixed and tall scrub, and burning tended to be the optimal action for intermediate levels of short scrub. The optimal action was to do nothing when the amount of short scrub was greater than 30%, because short scrub mostly transitions to optimal height scrub (i.e., that state with the highest demographic success of scrub-jays) in the absence of intervention. Monte Carlo simulation of the optimal policy suggested that some form of management would be required every year. We note, however, that estimates of scrub-height transition probabilities were subject to several sources of uncertainty, and so we explored the management implications of alternative sets of transition probabilities. Generally, our analysis demonstrated the difficulty of managing for a species that requires midsuccessional habitat, and suggests that innovative management tools may be needed to help ensure the persistence of scrub-jays at Merritt Island National Wildlife Refuge.

    To assess the impact of technician involvement on the completion of medication therapy management (MTM) services in a community pharmacy setting and to describe pharmacists' and technicians' perceptions of technician involvement in MTM-related tasks and their satisfaction with the technician's role in MTM. Prospective observational study. In the fall of 2015, pharmacists and selected technicians from 32 grocery store-based community pharmacies were trained to use technicians within MTM services. Completed MTM claims were evaluated at all pharmacies for 3 months before training and 3 months after training. An electronic survey, developed with the use of competencies taught in the training and relevant published literature, was distributed via e-mail to trained employees 3 months after training. The total number of completed MTM claims at the 32 pharmacy sites was higher during the posttraining time period (2687 claims) versus the pretraining period (1735 claims). Of the 182 trained participants, 112 (61.5%) completed the survey. Overall, perceived technician involvement was lower than expected. However, identifying MTM opportunities was the most commonly reported technician MTM task, with 62.5% of technicians and 47.2% of pharmacists reporting technician involvement. Nearly one-half of technicians (42.5%) and pharmacists (44.0%) agreed or strongly agreed they were satisfied with the technician's role in MTM services, and 40.0% of technicians agreed that they were more satisfied with their work in the pharmacy after involvement in MTM. Three months after initial training of technicians in MTM, participation of technicians was lower than expected. However, the technicians involved most often reported identifying MTM opportunities for pharmacists, which may be a focus for future technician trainings. In addition, technician involvement in MTM services may increase satisfaction with many aspects of work for actively involved technicians. Copyright © 2018 American

    One hundred and seventy-eight dental laboratory technicians and 69 non-exposed controls participated in an epidemiological respiratory study. Eight technicians who had a mean of 28 years grinding nonprecious metal alloys were diagnosed as having a simple pneumoconiosis by chest radiograph. Mean values for per cent predicted FVC and FEV1 were reduced among male nonsmoker technicians compared to male nonsmoker controls; after controlling for age, there was also a reduction in spirometry with increasing work-years. An industrial hygiene survey was conducted in 13 laboratories randomly selected from 42 laboratories stratified by size and type of operation in the Salt Lake City, Utah metropolitan area. Personal exposures to beryllium and cobalt exceeded the Threshold Limit Values (TLVs) in one laboratory. Occupational exposures in dental laboratories need to be controlled to prevent beryllium-related lung disorders as well as simple pneumoconiosis

    U.S. photonics organizations need about 800 new photonics technicians each year. Thirty-one community and technical colleges have approximately 700 students enrolled in photonics related programs; about 275 of them complete their coursework and enter the workforce each year. A disparity exists between the demand and supply of qualified photonics technicians in the U.S. OP-TEC, the National Center for Optics and Photonics Education is a consortium of seven colleges, under the leadership of the University of Central Florida, and sponsored by NSF. OP-TEC's mission is to increase the quantity and quality of photonics technicians prepared at two-year colleges. OP-TEC maintains the National Photonics Skill Standards for Technicians, provides curriculum models, teaching materials, faculty training/professional development and planning services to strengthen existing college photonics programs and to attract and support new ones. OP-TEC is converting its text materials to E-Books to support students in technical programs. Through OP-TEC's recruitment efforts 84 additional colleges are interested in initiating new photonics programs. The OP-TEC Photonics College Network (OPCN) consists of 28 colleges that are currently providing photonics education. This fall OPCN will lead an additional national effort to further educate employed photonics technicians through on-line courses, complemented by lab experiences at nearby colleges. OP-TEC is expanding its outreach to photonics employers and colleges by regionalizing its approach to offering its services. OP-TEC is also planning to develop new curricula and instructional materials for AAS programs to prepare Precision Optics Technicians. This paper will detail OP-TEC's work with particular emphases on its materials and services.

    To describe the clinical and radiological findings of abdominopelvic involvement in scrub typhus. Abdominopelvic computed tomography (CT) of 78 patients with scrub typhus were evaluated by two readers. The presence of gallbladder wall thickening, arterial inhomogeneous enhancement of the liver, periportal edema, splenic infarction, hepatomegaly, splenomegaly, ascites, pleural effusion, and sites of lymphadenopathy were evaluated. Patients were divided into four clinical subgroups according to laboratory findings. Association between imaging findings and subgroups was analyzed by Chi squared test or Fisher's exact test. The most common CT finding was hepatomegaly (74.4%), followed by splenomegaly (66.7%). The majority of patients had at least three areas of abdominopelvic lymphadenopathy (71.8%). Pelvic lymphadenopathy was most commonly seen when eschar was found in the ipsilateral lower extremity (left, n = 5/7; right, n = 8/13). Significant association between hepatic dysfunction and perigastric lymphadenopathy was documented (p = 0.03). Scrub typhus has a spectrum of variable clinical and radiological findings mimicking those of acute hepatitis. Diffuse abdominopelvic lymphadenopathy involving the retroperitoneum and pelvic area may aid in early diagnosis of scrub typhus. Perigastric lymphadenopathy could be a sign of severe scrub typhus combined with hepatic dysfunction.

    A Containment Filtered Venting System (CFVS) is the most interested device to mitigate a threat against containment integrity under the severe accident of nuclear power plant by venting with the filtration of the fission products. FNC technology and partners have been developed the self-priming scrubbing nozzle used for the CFVS which is based on the venturi effect. The thermal-hydraulic performances such as passive scrubbing water suction as well as pressure drop across the nozzle have been tested under various thermal-hydraulic conditions. The two types of test section have been built for testing the thermal-hydraulic performance of the self-priming scrubbing nozzle. Through the visualization loop, the liquid suction performance through the slit, pressure drop across the nozzle are measured. The passive water suction flow through the suction slit at the throat is important parameter to define the scrubbing performance of the self-priming scrubbing nozzle. The water suction flow is increased with the increase of the overhead water level at the same inlet gas flow. It is not so much changed with the change of inlet gas flow at the overhead water level.

    Clinical diagnosis of scrub typhus is often difficult because the symptoms are very similar to those of other febrile illness such as dengue, leptospirosis, malaria and other viral hemorrhagic fevers. Though better diagnostic tests are available for rickettsial diseases and scrub typhus elsewhere, the Weil-Felix test is still commonly used in India, mainly because microimmunofluorescence assays (M-IFA) were not available in India till recently and relevant staff had insufficient training. The present study was performed to investigate the performance of M-IFA, IgM ELISA, and Weil-Felix test on 546 non-repeated serum samples from subjects suspected of having scrub typhus. One hundred and forty-three of these 546 samples were positive by M-IFA; these cases were also confirmed clinically to have scrub typhus based on their dramatic responses to doxycycline therapy. IgM ELISA was positive in 122 of the 143 M-IFA positive cases and the Weil-Felix test in 96. Though the Weil-Felix test is a heterophile agglutination test, it was found in this study to have good specificity but far too little sensitivity to use as a routine diagnostic test. IgM ELISA can be a good substitute for M-IFA. Incorporation of multiple prototype antigens on M-IFA slides is likely one of the reasons for its superior performance. As newer and better diagnostic assays become available for scrub typhus diagnosis in developed countries, it will be imperative to also use such tests in other endemic countries to prevent over- or under-diagnosis of scrub typhus. © 2015 The Societies and Wiley Publishing Asia Pty Ltd.

    Scrub typhus is an endemic disease in Asia. It has been a rural disease, but indigenous urban cases have been observed in Seoul, South Korea. Urban scrub typhus may have a significant impact because of the large population. Indigenous urban scrub typhus was epidemiologically identified in Seoul, the largest metropolitan city in South Korea, using national notifiable disease data from 2010 to 2013. For detailed analysis of clinical features, patients from one hospital that reported the majority of cases were selected and compared to a historic control group. Chigger mites were prospectively collected in the city using a direct chigger mite-collecting trap, and identified using both phenotypic and 18S rDNA sequencing analyses. Their infection with Orientia tsutsugamushi was confirmed by sequencing the 56-kDa antigen gene. Eighty-eight cases of urban scrub typhus were determined in Seoul. The possible sites of infection were mountainous areas (56.8%), city parks (20.5%), the vicinity of one's own residence (17.0%), and riversides (5.7%). Eighty-seven chigger mites were collected in Gwanak mountain, one of the suspected infection sites in southern Seoul, and seventy-six (87.4%) of them were identified as Helenicula miyagawai and eight (9.2%) as Leptotrombidium scutellare. Pooled DNA extracted from H. miyagawai mites yielded O. tsutsugamushi Boryong strain. Twenty-six patients from one hospital showed low APACHE II score (3.4 ± 2.7), low complication rate (3.8%), and no hypokalemia. We identified the presence of indigenous urban scrub typhus in Seoul, and a subgroup of them had mild clinical features. The chigger mite H. miyagawai infected with O. tsutsugamushi within the city was found. In endemic area, urban scrub typhus needs to be considered as one of the differential febrile diseases and a target for prevention.

    The aim of this study is to identify the factors associated with the occurrence of pleural effusion and to investigate the characteristics of pleural effusion in scrub typhus. We conducted a retrospective analysis of the medical records of scrub typhus patients between January 2004 and December 2011 at Chosun University Hospital in South Korea. A total of 445 scrub typhus patients were divided into the following two groups: without (n = 352) or with pleural effusion (n = 93). The data of 18 scrub typhus patients who underwent thoracentesis were summarized. Multivariate analysis demonstrated that the following factors were associated with the occurrence of pleural effusion in scrub typhus: older age (odds ratio [OR] = 1.029, P = 0.037, confidence interval [CI] = 1.002-1.056); male gender (OR = 1.924, P = 0.020, CI = 1.109-3.340); presence of heart failure (OR = 2.628, P = 0.039, CI = 1.052-6.565); and lower albumin (OR = 0.107, P ≤ 0.001, CI = 0.058-0.196). Most pleural effusion presentations were bilateral (88 %) and small (91 %). The effusion had transudate characteristics in 7 patients and exudate characteristics in 11 patients based on Light's criteria. This study provided the first data regarding the following four independent risk factors associated with the occurrence of pleural effusion: older age; male gender; the presence of heart failure; and lower albumin. The pleural effusion presentations in scrub typhus patients were bilateral and small in most cases, with transudate and/or exudate characteristics.

    Operating theatre scrub nurses (OTSNs) are not required to have undertaken a secondary or specialist post-registration theatre qualification to work in the operating theatre (OT) setting in the UK. From the systematic review there is only very limited literature or research in how technical scrub skills are acquired. This study explores the lived experiences of OTSNs learning technical scrub skills. The study employed the qualitative methodology of interpretative phenomenological analysis. Data was collected from six participating OTSNs using semi-structured interviews. Four superordinate themes emerged: How technical scrub skills are established, Gatekeepers, How the learner feels whilst learning and, Reflections of the experienced scrub nurse. The study found that the experiences of OTSNs learning technical scrub skills are varied and a variety of teaching and learning methods are utilised. These experiences were influenced by the team, mentor and surgeon within the OT environment. Lived experiences were also influenced by organisational structure and service pressures within the NHS.

    To determine the contribution of Orientia tsutsugamushi, the agent of scrub typhus, as a cause of acute encephalitis syndrome (AES) in Assam, India, we conducted a retrospective study of hospital patients with symptoms of AES during 2013-2015. Our findings suggest that O. tsutsugamushi infection leads to AES and the resulting illness and death.

    Patients with scrub typhus often complain of myalgia, but a comprehensive study on muscle dysfunction is lacking. We therefore report the clinical, electromyographic and muscle biopsy findings in patients with scrub typhus. Consecutive patients with scrub typhus were included, and their clinical and laboratory findings were noted. The patients with myalgia or weakness and elevated serum creatine kinase (CK) were considered to have muscle involvement. Electromyography (EMG) and muscle biopsy were done in some patients. Patients were treated with doxycycline 200mg daily for 7 days, and their clinical and biochemical outcome on discharge and one month were evaluated. 13 out of 33 (39.4%) patients had muscle involvement and their CK levels ranged between 287 and 3166 (859 ± 829) U/L. EMG revealed short duration polyphasic potentials, and muscle histopathology revealed evidence of vasculitis. There were significant correlations between severity of weakness and CK levels (r = -0.6; p scrub typhus. Although muscle histopathology showed evidence of vasculitis, patients responded to doxycycline. Copyright © 2014 Elsevier B.V. All rights reserved.

    To determine the prevalence and risk factors of scrub typhus in Tamil Nadu, South India. We performed a clustered seroprevalence study of the areas around Vellore. All participants completed a risk factor survey, with seropositive and seronegative participants acting as cases and controls, respectively, in a risk factor analysis. After univariate analysis, variables found to be significant underwent multivariate analysis. Of 721 people participating in this study, 31.8% tested seropositive. By univariate analysis, after accounting for clustering, having a house that was clustered with other houses, having a fewer rooms in a house, having fewer people living in a household, defecating outside, female sex, age >60 years, shorter height, lower weight, smaller body mass index and smaller mid-upper arm circumference were found to be significantly associated with seropositivity. After multivariate regression modelling, living in a house clustered with other houses, female sex and age >60 years were significantly associated with scrub typhus exposure. Overall, scrub typhus is much more common than previously thought. Previously described individual environmental and habitual risk factors seem to have less importance in South India, perhaps because of the overall scrub typhus-conducive nature of the environment in this region. © 2017 John Wiley & Sons Ltd.

    Highlights: • Pool temperature effects on the FP removal were not clearly concluded in the previous publications. • It was confirmed that the removal efficiency decreased with temperature around the boiling point. • A modified empirical formula for FP removal was proposed as a function of sub-cooling temperature. • DF could be predicted with an accuracy within a factor of 2 with the proposed formula. - Abstract: The wet-well of boiling water reactors plays important roles not only to suppress the pressure in the primary containment vessel due to steam scrubbing effects during severe accidents but also to mitigate release of radioactive fission products (FP), aerosols and particulates, into the environment. The effects of steam scrubbing in the wet-well on FP removal have been well studied and reported by changing major parameters determining the removal efficiencies, e.g., aerosol diameters, submergence (depth of scrubbing nozzles) and steam/non-condensable gas volume fraction. Unfortunately, the effects of pool temperature on the FP removal were not clearly concluded in the previous publications, though it would be easily expected that boiling in the pool resulted in reduced aerosol removal efficiency. In order to determine the temperature effects on FP removal efficiency, amounts of cesium in aerosols released from scrubbing pool were measured by changing pool temperature in mini and medium scale scrubbing experiments, and then, it was confirmed that the removal efficiency clearly decreased with temperature around the boiling point. Then, a modified empirical formula to express the FP removal around the boiling point temperature was proposed as a function of sub-cooling temperature by applying the effective steam volume fraction, which was designated as the volume ratio of condensed steam in the pool versus the sum of input steam and non-condensable gas. By comparing the measured removal efficiency with the calculated, it was validated that the

    Full Text Available Context: Scrub typhus is an acute febrile illness caused by Orientia tsutsugamushi. The disease is under-diagnosed in India, because of low index of suspicion and also due to its nonspecific presentation, and lack of confirmatory diagnostic tests. Aims: This study was undertaken to diagnose scrub typhus in patients with undifferentiated fevers by serology and molecular methods. Materials and Methods: A total of 68 blood samples were collected from patients clinically suspected to have scrub typhus. After transportation to the laboratory, the serum was separated from the blood and subjected to rapid card test. The ethylenediaminetetraacetic acid blood samples were subjected to DNA extraction using QIAamp DNA Mini Kit followed by nested polymerase chain reaction (nPCR. Results: 24/68 (35.29% cases showed the presence of antibody against scrub typhus by serology. 6/68 (8.8% patients showed the presence of outer membrane protein antigen gene 56 kDa by nPCR. 5/24 serology positive cases showed the presence of 56 kDa outer membrane protein antigen gene by nPCR. A large number of cases positive by serology were negative by PCR which may indicate a low sensitivity of this test either due to low copy numbers or due to excess host DNA. Conclusion: Delay in treatment may increase disease severity and leads to higher mortality. Thus, molecular methods of diagnosis may aid in the early diagnosis of infection and enable prompt treatment. This is the first report on the diagnosis of scrub typhus in the suburbs of Chennai using molecular methods and reemphasizes the need for increased awareness of rickettsial infections in rural areas.

    Occupational lung diseases are caused by several toxic substances including heavy metals; however, the exact pathologic mechanisms remain unknown. In the workplace, dental technicians are often exposed to heavy metals such as cobalt, nickel, or beryllium and occasionally develop occupational lung diseases. We described a case of occupational lung disease in a patient who was employed as a dental technician for over a decade. A 31-year-old, non-smoking woman presented with productive cough and shortness of breath of several weeks duration. Chest computed tomography revealed a large number of scattered, bilateral small pulmonary nodules throughout the lung field, and multiple mediastinal lymph nodes enlargement. Percutaneous needle biopsy showed multifocal small granulomas with foreign body type giant cells suggestive of heavy metals inhalation. The patient's condition improved on simple avoidance strategy for several months. This case highlighted the importance of proper workplace safety.

    Full Text Available The most applicable models in safety management put the human factors, employers’ attitudes and behaviors at the center. This study reports an investigation of job satisfaction among business aviation technicians. A demographic information form and Job Satisfaction Survey (JSS were used to collect data from 44 individuals. Data was analyzed using ANOVA and Student’s t-test. Our results show that there is significant difference in total job satisfaction levels with regard to marital status while other personal factors are not related to the total job satisfaction levels. However several sub dimensions of job satisfaction are affected by the workers’ military or civilian origin, their training background, types of companies they work in or their license category. No difference is found in age and position groups. Secondly, study shows that technicians are the most satisfied from the nature of their work, while they are the least satisfied by operational procedures.

Two statewide meetings of the Iowa Pharmacy Association. Pharmacy technicians. One 2-hour continuing education (CE) course about smoking cessation for pharmacy technicians. Changes in scores before and after the CE sessions among three domains (knowledge, efficacy, and outcome) of a validated survey instrument. Fifty-one technicians completed both the presession and postsession questionnaire. For the three survey domains, technicians' knowledge (P = .034), efficacy (P < .001), and outcome (P < .001) showed significant improvement between the presession and postsession surveys (Wilcoxon signed rank test). Pharmacy technicians who attended a CE program on smoking cessation improved their knowledge, attitudes, and self-confidence in helping smokers quit. Additional research should be conducted to test the role of pharmacy technicians in smoking cessation promotion.

    Florida scrub-jays Aphelocoma coerulescens are listed as threatened under the Endangered Species Act due to loss and degradation of scrub habitat. This study concerned the development of an optimal strategy for the restoration and management of scrub habitat at Merritt Island National Wildlife Refuge, which contains one of the few remaining large populations of scrub-jays in Florida. There are documented differences in the reproductive and survival rates of scrubjays among discrete classes of scrub height (strategy that would maximize the long-term growth rate of the resident scrub-jay population. We used aerial imagery with multistate Markov models to estimate annual transition probabilities among the four scrub-height classes under three possible management actions: scrub restoration (mechanical cutting followed by burning), a prescribed burn, or no intervention. A strategy prescribing the optimal management action for management units exhibiting different proportions of scrub-height classes was derived using dynamic programming. Scrub restoration was the optimal management action only in units dominated by mixed and tall scrub, and burning tended to be the optimal action for intermediate levels of short scrub. The optimal action was to do nothing when the amount of short scrub was greater than 30%, because short scrub mostly transitions to optimal height scrub (i.e., that state with the highest demographic success of scrub-jays) in the absence of intervention. Monte Carlo simulation of the optimal policy suggested that some form of management would be required every year. We note, however, that estimates of scrub-height transition probabilities were subject to several sources of uncertainty, and so we explored the management implications of alternative sets of transition probabilities. Generally, our analysis demonstrated the difficulty of managing for a species that requires midsuccessional habitat, and suggests that innovative management tools may be needed to

    Full Text Available What significant changes are librarians and library technicians experiencing in their roles? A survey put forward across Canada to librarians and library technicians addressing this question was conducted in February 2014. Eight hundred eighty-two responses were obtained from librarians, defined as MLIS graduates, and library technicians, defined as graduates from a two-year library diploma program. Respondents needed to have been employed in the last two years in these roles and students of either an MLIS or LIT program were also welcome to participate. The results suggest that both librarians and library technicians perceive their roles as growing in scope and complexity and that the lines of responsibility are blurring. A majority of respondents indicated that they perceive a change in their roles in the past five years and commented on what the perceived changes were. Librarian and library technician roles may be shifting away from what may be viewed as traditional or clearly defined responsibilities and both librarians and library technicians may be taking on new tasks as well as experiencing task overlap. All library staff will need to be fluid, adaptable, and open to change. Library school curricula and workplace training need to incorporate the development of these competencies. Quels sont les changements importants éprouvés par les bibliothécaires et les bibliotechniciens dans leurs rôles?

    Full Text Available Scrub typhus is a rickettsial infection commonly seen in Asia. The clinical presentation ranges from nonspecific febrile illness to potentially fatal multiorgan involvement such as liver, kidney, or lung. Central nervous system involvement is uncommon. We report a 45-year-old female renal transplant recipient who presented with fever, headache, meningeal signs, graft dysfunction, and eschar. IgM antibodies against Orientia tsutsugamushi were positive by enzyme-linked immunosorbent assay. Despite oral doxycycline therapy for 5 days, she did not improve but responded well to intravenous azithromycin. To the best of our knowledge, scrub typhus as a cause of meningitis in a renal transplant recipient has not been reported so far.

    2008-02-01

    Full Text Available Scrub typhus is a zoonotic disease caused by Orientia tsutsugamushi, which is transmitted by chiggers. The target cells of this rickettsia are poorly defined in humans. Immunohistochemical staining of tissue sections of patients with scrub typhus is helpful in investigating the target cells of this rickettsia in different organs. We studied two autopsy specimens by immunohistochemical staining using a specific antibody against O. tsutsugamushi. Rickettsiae were located in endothelial cells in all of the organs evaluated, namely heart, lung, brain, kidney, appendix and skin, within cardiac muscle cells and renal tubular epithelial cells, and in macrophages located in the lymph node, liver and spleen. In conclusion, O. tsutsugamushi may disseminate into multiple organs through endothelial cells and macrophages, resulting in the development of fatal complications.

    Scrub typhus infection is an important cause of acute undifferentiated fever in South East Asia. The clinical picture is characterized by sudden onset fever with chills and non-specific symptoms that include headache, myalgia, sweating and vomiting. The presence of an eschar, in about half the patients with proven scrub typhus infection and usually seen in the axilla, groin or inguinal region, is characteristic of scrub typhus. Common laboratory findings are elevated liver transaminases, thrombocytopenia and leukocytosis. About a third of patients admitted to hospital with scrub typhus infection have evidence of organ dysfunction that may include respiratory failure, circulatory shock, mild renal or hepatic dysfunction, central nervous system involvement or hematological abnormalities. Since the symptoms and signs are non-specific and resemble other tropical infections like malaria, enteric fever, dengue or leptospirosis, appropriate laboratory tests are necessary to confirm diagnosis. Serological assays are the mainstay of diagnosis as they are easy to perform; the reference test is the indirect immunofluorescence assay (IFA) for the detection of IgM antibodies. However in clinical practice, the enzyme-linked immuno-sorbent assay is done due to the ease of performing this test and a good sensitivity and sensitivity when compared with the IFA. Paired samples, obtained at least two weeks apart, demonstrating a ≥ 4 fold rise in titre, is necessary for confirmation of serologic diagnosis. The mainstay of treatment is the tetracycline group of antibiotics or chloramphenicol although macrolides are used alternatively. In mild cases, recovery is complete. In severe cases with multi-organ failure, mortality may be as high as 24%. PMID:26261776

    This study aimed to investigate the opinions of pharmacists and technicians regarding the ability of New Zealand technicians to take on an advanced checking technician role. A survey was developed to investigate the opinions regarding the introduction of this new role. The questions covered are: perceived ability to take on the role, training requirements and competence. Surveys were sent to pharmacists whose contact details are available for research purposes (n = 2095) and to all pharmacies in New Zealand (both community and hospital) for the attention of technicians (n = 858). The results were analysed using IBM SPSS and thematic analysis of comments was conducted. A total of 1221 surveys were returned (pharmacists = 736 and technicians = 485). The majority of the technicians (83%) believed that 'some' technicians could work in a CT role, compared with 73% of the pharmacists. Over two-thirds (69%) of the technicians felt comfortable checking a prescription at their current level of training compared with 53% of pharmacists. Both groups' comfort increased with further specific training for the technicians. The majority of both of these groups supported the change in roles. Pharmacists were less confident that technicians could take on this role now, but were more comfortable after extra training had been completed. The technicians, however, were confident they could take on this role now but would take on extra training if needed. © 2015 Royal Pharmaceutical Society.

    Studies on the topic of burnout measure the effects of emotional exhaustion (EE), depersonalization (DP) (negative or cynical attitudes toward work), and reduced sense of personal accomplishment (PA). While the prevalence of burnout in practicing emergency medicine (EM) professionals has been studied, little is known of the prevalence and factors across physicians, nurses, technicians, and health information technicians working for the same institution. The aim of this study was to assess burnout differences across EM professional types.The total population of 250 EM professionals at 2 public urban hospitals in Turkey were surveyed using the Maslach Burnout Inventory and basic social- and work-related demographics. Descriptive statistics, ANOVA, and additional post hoc tests were computed.Findings show that EE and DP scores were high across all occupational groups, while scores on PA were low. There was a statistically significant difference between nurses and medical technicians (P nurses and medical technicians (P Burnout can be high across occupational groups in the emergency department. Burnout is important for EM administrators to assess across human resources. Statistically significant differences across socio-demographic groups vary across occupational groups. However, differences between occupational groups may not be explained effectively by the demographic factors assessed in this or other prior studies. Rather, the factors associated with burnout are incomplete and require further institutional, cultural, and organizational analyses including differentiating between job tasks carried out by each EM job type.

    A long held principle is that for every engineer and scientist there is a need for ten technicians to maximize the efficiency of the technology team for meeting needs of industry and government. Developing an adequate supply of technicians to meet the requirements of the materials related industry will be a challenge and difficult to accomplish. A variety of agencies feel the need and wish to support development of engineering materials technology programs. In a joint effort among Battelle Laboratories, the Department of Energy (DOE) and Northwest College and University Association for Science (NORCUS), the development of an engineering materials technology program for vocational programs and community colleges for the Pacific Northwest Region was recently completed. This effort has implications for a national model. The model Associate of Applied Science degree in Engineering Materials Technology shown provides a general structure. It purposely has course titles which need delimiting while also including a core of courses necessary to develop cognitive, affective and psychomotor skills with the underlining principles of math, science and technology so students have job entry skills, and so that students can learn about and adapt to evolving technology.

    Full Text Available Background & objectives: Scrub typhus is a major public health threat in South and Southeastern Asian countries including India. Understanding local patterns of disease and factors that place individuals at risk is pivotal to future preventive measures against scrub typhus. The primary aim of this study was to identify specific epidemiological and geographical factors associated with an increased risk of developing scrub typhus in this region. Methods: We mapped 709 patients from Tamil Nadu, Andhra Pradesh and Telangana who were admitted to the Christian Medical College (CMC Hospital, Vellore, Tamil Nadu, India, for the period 2006-2011, assessed seasonality using monthly counts of scrub typhus cases, and conducted a case-control study among a subset of patients residing in Vellore. Results: The geographic distribution of cases at CMC Hospital clusters around the Tamil Nadu-Andhra Pradesh border. However, distinct hotspots clearly exist distal to this area, near Madurai and the coast in Tamil Nadu, and in the Northeast of Andhra Pradesh. Seasonally, the highest numbers of cases were observed in the cooler months of the year, i.e. September to January. In the case-control analysis, cases were more likely to be agricultural laborers (OR 1.79, 95% CI 1.01 - 3.15, not wear a shirt at home (OR 4.23, 95% CI 1.12 - 16.3, live in houses adjacent to bushes or shrubs (OR 1.95, 95% CI 1.08 - 3.53, and live in a single room home (OR 1.75, 95% CI 1.02 - 3.01. On binary logistic regression, the first three of these variables were statistically significant. Interpretation & conclusions: With the growing number of cases detected in India, scrub typhus is fast emerging as a public health threat and further research to protect the population from this deadly infection is essential. Health education campaigns focusing on the agricultural workers of Southern India, especially during the cooler months of the year, can serve as an important public health measure to

    Scrub typhus is a vector-borne disease, which has recently reemerged in China. In this study, we describe the distribution and incidence of scrub typhus cases in China from 2006 to 2014 and quantify differences in scrub typhus cases with respect to sex, age, and occupation. The results of our study indicate that the annual incidence of scrub typhus has increased during the study period. The number of cases peaked in 2014, which was 12.8 times greater than the number of cases reported in 2006. Most (77.97%) of the cases were reported in five provinces (Guangdong, Yunnan, Anhui, Fujian, and Shandong). Our study also demonstrates that the incidence rate of scrub typhus was significantly higher in females compared to males (P scrub typhus incidence, but also document an expansion in the geographic distribution throughout the country. © The American Society of Tropical Medicine and Hygiene.

    Timely diagnosis and prompt treatment can reduce the complications of scrub typhus. It is thus important to find easy laboratory tests to help in the diagnosis, especially in patients without eschar at initial presentation. Because serum aminotransferase elevation is common in scrub typhus, its associated factors and clinical implications need further investigations. We conducted a retrospective study in Kinmen, Taiwan, to collect clinically suspected scrub typhus patients notified to Taiwan Centers for Disease Control for confirmation during 2005-2010. Scrub typhus was diagnosed and Orientia tsutsugamushi was genotyped by serological or molecular assays. The laboratory data and clinical information were recorded for analysis. Overall, 344 suspected scrub typhus patients were reported to Taiwan Centers for Disease Control and 288 of them were certified scrub typhus. Scrub typhus patients had significantly more thrombocytopenia, serum aminotransferase elevation (76% vs. 54%, p = 0.001), higher frequency of fever, eschar, and lymphadenopathy, compared with nontyphus patients. Hepatic dysfunction in scrub typhus was associated with older age, longer fever duration, and absence of lymphadenopathy, but seemed to be unrelated to the rickettsial genotypes. Multivariate analysis showed that serum aminotransferase elevation (odds ratio: 3.75; p = 0.003; 95% confidence interval: 1.56-9.01) independently predicted scrub typhus. Furthermore, in suspected scrub typhus patients without eschar, 92% of true typhus patients had serum aminotransferase elevation compared with the nontyphus ones (odds ratio: 6.47; p = 0.028, 95% confidence interval: 1.23-34.11). Hepatic dysfunction in scrub typhus patients is associated with older age, longer fever duration, and absence of lymphadenopathy. Serum aminotransferase elevation can aid in the diagnosis of scrub typhus, especially in suspected patients without eschar. Copyright © 2014. Published by Elsevier B.V.

    Full Text Available Abstract Background Scrub typhus is an acute febrile illness caused by Orientia tsutsugamushi. Case presentations We encountered a patient with sensorineural hearing loss complicating scrub typhus, and three patients with scrub typhus who complained of otalgia, which was sudden onset, severe, paroxysmal, intermittent yet persistent pain lasting for several seconds, appeared within 1 week after the onset of fever and rash. The acute sensorineural hearing loss and otalgia were resolved after antibiotic administration. Conclusion When patients in endemic areas present with fever and rash and have sensorineural hearing loss or otalgia without otoscopic abnormalities, clinicians should suspect scrub typhus and consider empirical antibiotic therapy.

    AbstractCentral nervous system involvement manifesting as meningitis or meningoencephalitis is a known complication of scrub typhus, but very few spinal cord lesions such as acute transverse myelitis (ATM) have been reported in association with this disease. Scrub typhus patients with a spinal lesion present with neurologic symptoms including dysuria, motor, and sensory weakness. Herein, we describe a rare case of ATM associated with scrub typhus. Clinical characteristics, cerebrospinal fluid cytology, Orientia tsutsugamushi serum antibody titer, and serial magnetic resonance imaging scans resulted in a diagnosis of ATM associated with scrub typhus.

With an explorative and qualitative approach, four group interviews with scrub practitioners, surgeons and anaesthesia staff were conducted. The main differences found were related to communication and teamwork regarding scrub practitioners focus on the team and speaking up. Differences in the non-technical skills described in the behavioural markers are perhaps explained by cultural differences between Scotland and Denmark.

  1. Methods for training radiochemical technicians at ORNL

    International Nuclear Information System (INIS)

    Parrott, J.R.; Nicol, R.G.

    The training of personnel to carry out radiochemical operations at ORNL is a formidable and recurrent task since programs are constantly shifting. It is essential that provisions be made for the routine retraining of these personnel if they are to make effective contributions on a continuing basis. Training methods are described that have emerged as a result of thirty years experience in a variety of radiochemical pilot-plant programs. Emphasis is placed on training programs for technicians for the 233 U Processing Facility since essentially all aspects of radiochemical operations are encountered in this facility. These programs have included operations performed in glove boxes, hot-cell manipulator work handling high-neutron-emitting isotopes, and the entire spectrum of remote solvent extraction operations.

    Full Text Available There has been a rapid increase in the number of scrub typhus cases in Guangdong Province, China. For this reason, an epidemiologic study was conducted to understand the characteristics of scrub typhus epidemics in Guangdong. From 2006 to 2013, the incidence of human cases increased from 0.4321 to 3.5917 per 100,000 with a bimodal peak in human cases typically occurring between May and November. To detect the prevalence of Orientia tsutsugamushi among suspected human cases and rodents, we performed ELISA tests of IgM/IgG and nested PCR tests on 59 whole blood samples from the suspected cases and 112 spleen samples from the rodents. Suspected cases tested positive for anti-O. tsutsugamushi IgM and IgG 66.1% (39/59 and 50.8% (30/59 of the time, respectively. Additionally, 20.3% (12/59 of blood samples and 13.4% (15/112 of spleen samples were positive for PCR. Phylogenetic analysis revealed that there were four definable clusters among the 27 nucleotide sequences of the 56-kDa antigen genes: 44.4% Karp (12/27, 25.9% Kato (7/27, 22.2% Gilliam (6/27 and 7.4% TA763 (2/27. We concluded many suspected cases may result in diagnostic errors; therefore, it is necessary to perform laboratory tests on suspected cases in hospitals. The high infection rate of O. tsutsugamushi among the limited rodents tested suggested that further rodent sampling throughout the province is necessary to further define high-risk areas. Furthermore, the multiple co-circulating genotypes of O. tsutsugamushi play a key role in the pervasiveness of scrub typhus in the Guangdong area.

    Full Text Available BACKGROUND Scrub typhus is an underdiagnosed disease, but potentially treatable, if diagnosis is made with high index of suspicion. Deaths are attributable to late presentation, delayed diagnosis and drug resistance. MATERIALS AND METHODS The study was an observational study of prospective design conducted in the Department of General Medicine, Government Medical College, Kozhikode, over a period of one year. History, physical examination and relevant lab investigations were done in 70 patients in the study. RESULTS Majority of patients were in working class. Most common physical finding was lymphadenopathy. Eschar was present in 46% of patients. Majority responded to doxycycline. Case fatality was 14.3%. CONCLUSION 1. Most cases occurred during cooler months of the year (Oct-Feb. 2. Fever and headache were the most common symptoms. 3. Lymphadenopathy was the most common sign followed by splenomegaly. 4. Eschar was present in 46% cases. 5. Leucocytosis was associated with poor prognosis and increased complication like meningoencephalitis. 6. Hypoalbuminaemia was associated with increased incidence of complications like myocarditis and encephalitis. 7. More than 2 times, elevation of transaminases was a poor prognostic marker. 8. Most common and important complication was Acute Kidney Injury (AKI. 9. Microangiopathic haemolysis could possibly be a contributory factor for high incidence of AKI associated with scrub typhus. 10. Rampant NSAID use is another contributory factor for high incidence of AKI associated with scrub typhus. 11. Resistance to doxycycline is emerging in our community and we should consider this possibility in cases with strong suspicion with no response to doxycycline.

    Plant analyses have shown that pool scrubbing can play an important role in source term during PWR risk dominant sequences. An examination ofboundary conditions governing fission products and aerosols transport through aqueous beds revealed that most of radioactivity is discharged into the pool under jet injection regime. This fact and the lack of experimental data under such conditions pointed the need of setting out an experimental programme which provided reliable experimental data to validate code models. In this report the major results of a pool scrubbing experimental programme carried out in PECA facility are presented. One of the major findings was that a remarkable fraction of particle absorption was not a function of the residence time of bubbles rising through the pool. Such a contribution was assumed to be associated to aerosol removal mechanisms acting at the pool entrance. As a consequence, a hydrodynamic experimental plan was launched to examine the gas behaviour during the initial stages in the pool. Size and shape of gas nuclei the pool were measured and fitted to a long normal distribution. Particularly, size was found to be quite sensitive to inletgas flow and at minor extent to gas composition and pool temperature. SPARC90 and BUSCA-AUG92 were used to simulate the retention tests. Whereas SPARC90 showed a pretty good agreement with experimental data, BUSCA-AUG92 results were far away from measurements in all the cases. SPARC90consistency apparently pointed out the important role of fission products and aerosols retention at the injection zone; nonetheless, a peer examination of pool scrubbing phenomenology at the pool entrance should be carried out to test both hydrodynamic and removal models. Hence, one of the major highlights drawn from this work was the need of further research under representative severe accident conditions (i.e., saturated pools, jet injection regimes, etc.), as well as separate effect tests to validate, improve and

  9. Self-Scrubbing Coal -- an integrated approach to clean air

    Energy Technology Data Exchange (ETDEWEB)

    1997-12-31

    Carefree Coal is coal cleaned in a proprietary dense-media cyclone circuit, using ultrafine magnetite slurries, to remove noncombustible material, including up to 90% of the pyritic sulfur. Deep cleaning alone, however, cannot produce a compliance fuel from coals with high organic sulfur contents. In these cases, Self-Scrubbing Coal will be produced. Self-Scrubbing Coal is produced in the same manner as Carefree Coal except that the finest fraction of product from the cleaning circuit is mixed with limestone-based additives and briquetted. The reduced ash content of the deeply-cleaned coal will permit the addition of relatively large amounts of sorbent without exceeding boiler ash specifications or overloading electrostatic precipitators. This additive reacts with sulfur dioxide (SO{sub 2}) during combustion of the coal to remove most of the remaining sulfur. Overall, sulfur reductions in the range of 80--90% are achieved. After nearly 5 years of research and development of a proprietary coal cleaning technology coupled with pilot-scale validation studies of this technology and pilot-scale combustion testing of Self-Scrubbing Coal, Custom Coals Corporation organized a team of experts to prepare a proposal in response to DOE`s Round IV Program Opportunity Notice for its Clean Coal Technology Program under Public Law 101-121 and Public Law 101-512. The main objective of the demonstration project is the production of a coal fuel that will result in up to 90% reduction in sulfur emissions from coal-fired boilers at a cost competitive advantage over other technologies designed to accomplish the same sulfur emissions and over naturally occurring low sulfur coals.

    Scrub typhus is endemic in the Asia-Pacific region including China, and the number of reported cases has increased dramatically in the past decade. However, the spatial-temporal dynamics and the potential risk factors in transmission of scrub typhus in mainland China have yet to be characterized. This study aims to explore the spatiotemporal dynamics of reported scrub typhus cases in mainland China between January 2006 and December 2014, to detect the location of high risk spatiotemporal clusters of scrub typhus cases, and identify the potential risk factors affecting the re-emergence of the disease. Monthly cases of scrub typhus reported at the county level between 2006 and 2014 were obtained from the Chinese Center for Diseases Control and Prevention. Time-series analyses, spatiotemporal cluster analyses, and spatial scan statistics were used to explore the characteristics of the scrub typhus incidence. To explore the association between scrub typhus incidence and environmental variables panel Poisson regression analysis was conducted. During the time period between 2006 and 2014 a total of 54,558 scrub typhus cases were reported in mainland China, which grew exponentially. The majority of cases were reported each year between July and November, with peak incidence during October every year. The spatiotemporal dynamics of scrub typhus varied over the study period with high-risk clusters identified in southwest, southern, and middle-eastern part of China. Scrub typhus incidence was positively correlated with the percentage of shrub and meteorological variables including temperature and precipitation. The results of this study demonstrate areas in China that could be targeted with public health interventions to mitigate the growing threat of scrub typhus in the country.

    Scrub typhus is becoming the most common vector born disease in Guangzhou, southern China. In this study, we aimed to examine the effect of weather patterns on the incidence of Scrub typhus in the subtropical city of Guangzhou for the period 2006-2012, and assist public health prevention and control measures. Scrub typhus reported cases during the period of 2006-2012 in Guangzhou were obtained from National Notifiable Disease Report System (NNDRS). Simultaneous meteorological data including temperature, relative humidity, atmospheric pressure, sunshine, and rainfall were obtained from the documentation of the Guangzhou Meteorological Bureau. A negative binomial regression was used to identify the relationship between meteorological variables and scrub typhus. Annual incidence rates of scrub typhus from 2006 to 2012 were 3.25, 2.67, 3.81, 4.22, 4.41, 5.12, and 9.75 (per 100 000) respectively. Each 1°C rise in temperature corresponded to an increase of 14.98% (95% CI 13.65% to 16.33%) in the monthly number of scrub typhus cases, while a 1 hPa rise in atmospheric pressure corresponded to a decrease in the number of cases by 8.03% (95% CI -8.75% to -7.31%). Similarly, a 1 hour rise in sunshine corresponded to an increase of 0.17% or 0.54%, and a 1 millimeter rise in rainfall corresponded to an increase of 0.05% or 0.10%, in the monthly number of scrub typhus cases, depending on the variables considered in the model. Our study provided evidence that climatic factors were associated with occurrence of scrub typhus in Guangzhou city, China. Temperature, duration of sunshine, and rainfall were positively associated with scrub typhus incidence, while atmospheric pressure was inversely associated with scrub typhus incidence. These findings should be considered in the prediction of future patterns of scrub typhus transmission.

    Full Text Available Objectives: To explore the rate of pneumoconiosis in dental technicians (DTP and to evaluate the risk factors. Material and Methods: Data of 893 dental technicians, who were admitted to our hospital in the period January 2007–May 2012, from 170 dental laboratories were retrospectively examined. Demographic data, respiratory symptoms, smoking status, work duration, working fields, exposure to sandblasting, physical examination findings, chest radiographs, pulmonary function tests and high-resolution computed tomography results were evaluated. Results: Dental technicians’ pneumoconiosis rate was 10.1% among 893 cases. The disease was more common among males and in those exposed to sandblasting who had 77-fold higher risk of DTP. The highest profusion subcategory was 3/+ (according to the International Labour Organization (ILO 2011 standards and the large opacity rate was 13.3%. Conclusions: To the best of our knowledge, it was the largest DTP case series (N = 893/90 in the literature in English. Health screenings should be performed regularly for the early diagnosis of pneumoconiosis, which is an important occupational disease for dental technicians.

    To summarize the findings of a literature search on advancing the role of pharmacy technicians, including the types of training identified and the potential costs and benefits to both the technician and the pharmacy. A literature search of Scopus, Embase, and Medline was conducted on January 11, 2017. Original research, research reports, case studies, or association reports were included for review. Articles were considered to be relevant based on identification of an advanced pharmacy technician role or addressing additional training/education for technician functions. A standard data extraction form was used to collect study authors, article title, year published, journal title, study design, brief description of methods, primary outcome measures, advanced technician roles identified, additional education or training addressed, and additional costs and benefits identified in each article. A total of 33 articles were included for full review and data extraction. Study design varied, with 17 (52%) quantitative, 1 (3%) qualitative, 5 (15%) mixed-method, and 10 (30%) case study designs. Seventeen (52%) of the studies included were published after 2006. The mechanism of training was primarily through supervised on-the-job training, allowing technicians to assume administrative-based positions that facilitated a pharmacist-led clinical service, with either the pharmacist or the pharmacy receiving the greatest benefits. Although the literature supports technicians performing advanced roles in the pharmacy, resulting in either improved patient outcomes or opportunities for pharmacists to engage in additional clinical services, the benefits to the technician were primarily indirect, such as an increase in job satisfaction or a more desirable work schedule. If a technician is to take on additional roles that require completion of a formalized training or educational program, benefits that are more tangible may help to inspire technicians to pursue these roles.

    Full Text Available Scrub typhus is a potentially fatal mite-borne febrile illness, primarily of the Asia-Pacific Rim. With an endemic area greater than 13 million km2 and millions of people at risk, scrub typhus remains an underreported, often misdiagnosed febrile illness. A comprehensive, updatable map of the true distribution of cases has been lacking, and therefore the true risk of disease within the very large endemic area remains unknown. The purpose of this study was to establish a database and map to track human scrub typhus. An online search using PubMed and the United States Armed Forces Pest Management Board Literature Retrieval System was performed to identify articles describing human scrub typhus cases both within and outside the traditionally accepted endemic regions. Using World Health Organization guidelines, stringent criteria were used to establish diagnoses for inclusion in the database. The preliminary screening of 181 scrub typhus publications yielded 145 publications that met the case criterion, 267 case records, and 13 serosurvey records that could be georeferenced, describing 13,739 probable or confirmed human cases in 28 countries. A map service has been established within VectorMap (www.vectormap.org to explore the role that relative location of vectors, hosts, and the pathogen play in the transmission of mite-borne scrub typhus. The online display of scrub typhus cases in VectorMap illustrates their presence and provides an up-to-date geographic distribution of proven scrub typhus cases.

    We aimed to evaluate the relationships between climate variability, animal reservoirs and scrub typhus incidence in Southern China. We obtained data on scrub typhus cases in Guangzhou every month from 2006 to 2014 from the Chinese communicable disease network. Time-series Poisson regression models and distributed lag nonlinear models (DLNM) were used to evaluate the relationship between risk factors and scrub typhus. Wavelet analysis found the incidence of scrub typhus cycled with a period of approximately 8-12 months and long-term trends with a period of approximately 24-36 months. The DLNM model shows that relative humidity, rainfall, DTR, MEI and rodent density were associated with the incidence of scrub typhus. Our findings suggest that the incidence scrub typhus has two main temporal cycles. Determining the reason for this trend and how it can be used for disease control and prevention requires additional research. The transmission of scrub typhus is highly dependent on climate factors and rodent density, both of which should be considered in prevention and control strategies for scrub typhus.

    Conclusions: This study indicates that improved diagnosis and timely treatment are important factors for the prevention of severe scrub typhus. When scrub typhus patients present with a rash, lymphadenopathy, or blood platelet count <100 × 109/l, clinicians should be alert to the appearance of severe complications.

    Scrub typhus is transmitted by the larval stage of trombiculid mites. Environmental factors, including land cover and land use, are known to influence breeding and survival of trombiculid mites and, thus, also the spatial heterogeneity of scrub typhus risk. Here, a spatially autoregressive modelling framework was applied to scrub typhus incidence data from Taiwan, covering the period 2003 to 2011, to provide increased understanding of the spatial pattern of scrub typhus risk and the environmental and socioeconomic factors contributing to this pattern. A clear spatial pattern in scrub typhus incidence was observed within Taiwan, and incidence was found to be significantly correlated with several land cover classes, temperature, elevation, normalized difference vegetation index, rainfall, population density, average income and the proportion of the population that work in agriculture. The final multivariate regression model included statistically significant correlations between scrub typhus incidence and average income (negatively correlated), the proportion of land that contained mosaics of cropland and vegetation (positively correlated) and elevation (positively correlated). These results highlight the importance of land cover on scrub typhus incidence: mosaics of cropland and vegetation represent a transitional land cover type which can provide favourable habitats for rodents and, therefore, trombiculid mites. In Taiwan, these transitional land cover areas tend to occur in less populated and mountainous areas, following the frontier establishment and subsequent partial abandonment of agricultural cultivation, due to demographic and socioeconomic changes. Future land use policy decision-making should ensure that potential public health outcomes, such as modified risk of scrub typhus, are considered.

    The process used in preparing this administrative report provided the means of documenting departmental support of technician task expansion, cost benefits, increased availability of professional time, and the need for a dynamic department. Some of the benefits to St. Luke's Regional Medical Center and its Pharmacy Department were an increase in technician job satisfaction, improved quality of patient care attributable to the increased scope of pharmacy service, and up to 8554 hours per year of professional time available for more clinically oriented responsibilities. If technician turnover were decreased by half, technician pricing errors eliminated, and technicians assumed the identified technical tasks, potential monetary benefits could be as much as +116,900 per year. The departmental cost of implementing these recommendations would be an additional 4.16 technician FTEs, and the professional time for training, supervising, and coordinating technicians and functions. These recommendations were well received by pharmacy administration, and the committee was asked to develop a list of priorities and an implementation plan for administrative approval.

    The successful enactment of mandatory pharmacy technician certification in Kansas is described. In 2004, Kansas began requiring registration of all pharmacy technicians with the state board of pharmacy. Registration identified individuals working as pharmacy technicians but did not require any specific education or certification. In September 2012, the Kansas Board of Pharmacy created a task force of key stakeholders including pharmacists from multiple areas of practice, the University of Kansas School of Pharmacy, organizational leaders from the Kansas Council of Health-System Pharmacists (KCHP) and Kansas Pharmacists Association, and professional lobbyists. The goals of this task force were to research practices of technician certification in other states and to make recommendations to the state board of pharmacy on how Kansas could accomplish mandatory technician certification. The task force outlined the steps needed to achieve legislation that could be supported by the members. These topics included the creation of a technician trainee category, grandfathering certain technicians who had been practicing for a designated period of time, state board-approved exemptions, training requirements, age and education requirements, continuing-education requirements, and pharmacist:technician ratio. The recommendations were finalized at the August 2013 Kansas Pharmacy Summit, and the proposed legislation was introduced and passed during the 2014 legislative session. KCHP members learned many valuable lessons about advocacy and the legislative process with this initiative, including building relationships, working with legislators, and working with other professional organizations. The formation of a task force led to the successful passage of a bill granting the Kansas Board of Pharmacy the authority to issue regulations regarding mandatory pharmacy technician certification.

    Full Text Available Introduction: Causation of surgical site infection (SSI following craniotomy is multifactorial. Most preventive strategies (including site preparation and antibiotic prophylaxis revolve around reducing preoperative contamination of the local site. There is little evidence, however, linking site contamination with postoperative infections. This is important given the preference for performing non-shaved cranial surgery. We undertook a prospective study to document the scalp flora in neurosurgical patients in an Indian setting and to assess possible association with SSI. Materials and Methods: A prospective study recruited 45 patients undergoing non-shaved clean craniotomies for various brain tumors. Standard perioperative procedures and antibiotic policy were employed. Prior to and immediately following the pre-surgical scrubbing, we collected swabs and evaluated their growth qualitatively. SSI was documented adhering to CDC guidelines. The association of swab-positivity with various parameters (including SSI was evaluated. Results: Pre-scrub positivity was seen in 18 of 44 patients, three of them developed subsequent SSI. Most were known skin contaminants. Five patients had swab positivity after scrubbing, though none of these developed any SSI. Four of these five had pre-scrub positivity. In three the same organisms persisted (two being Staphylococcus aureus, and one had different growth post-scrub, whereas one patient developed new growth (contaminant mycelial fungus in the post-scrub swab. We did not find any association between swab positivity and SSI. Swab positivity was also not related to hair-length or hygiene. Conclusion: Scalp flora in Indian patients is similar to that described. Pre-surgical preparation does not always eliminate this contamination (especially staphylococcus. However, this does not necessarily translate into increased SSI. Moreover, the results also provide objective evidence to support the performance of non

    Plant analyses nave shown that pool scrubbing can play an important role in source term during PWR risk dominant sequences. An examination of boundary conditions governing fission products and aerosols transport through aqueous beds revealed that most of radioactivity is discharged into the pool under jet injection regime. This fact and the lack of experimental data under such conditions pointed the need of setting out an experimental programme which provided reliable experimental data to validate code models. In this report the major results of a pool scrubbing experimental programme carried out in PECA facility are presented. One of the major findings was that a remarkable fraction of particle absorption was not a function of the residence time of bubbles rising through the pool. Such a contribution was assumed to be associated to aerosol removal mechanism acting at the pool entrance. As a consequence. a hydrodynamic experimental plan was launched to examine the gas behaviour during the initial stages in the pool. Size and shape of gas nuclei in the pool were measured and fitted to a lognormal distribution. Particularly, size was found to be quite sensitive to inlet gas flow and at minor extent to gas composition and pool temperature. SPARC90 and BUSCA-AUG92 were used to simulate the retention tests. Whereas SPARC90 showed a pretty good agreement with experimental data, BUSCA-AUG92 results were far away from measurements in all the cases. SPARC90 consistency apparently pointed out the important role of fission products and aerosols retention at the injection zone; nonetheless, a peer examination of pool scrubbing phenomenology at the pool entrance should be carried out to test both hydrodynamic and removal models. Hence, one of the major high lights drawn from this work was the need of further research under representative severe accident conditions (i.e., saturated pools, jet injection regimes, etc.), as well as separate effect tests to validate, improve and

    Objective: To understand the epidemiological characteristics of scrub typhu s and influencing factors in Yunnan province, and provide further information for the prevention and control of scrub typhus. Methods: Based on the incidence data of scrub typhus reported in Yunnan from 2006 to 2013, the epidemiological characteristics of scrub typhus were analyzed and related environmental factors were identified with panel negative binomial regression model. Results: A total of 8 980 scrub typhus cases were reported during 2006-2013 in Yunnan. The average annual incidence was 2.46/100 000, with an uptrend observed. Natural focus expansion was found, affecting 71.3% of the counties in 2013. The epidemic mainly occurred in summer and autumn with the incidence peak during July-October. The annual incidence was higher in females than in males. More cases occurred in children and farmers, the proportions of cases in farmers and pre-school aged children showed an obvious increase. Panel negative binomial regression model indicated that the transmission risk of scrub typhus was positive associated with monthly temperature and monthly relative humidity. Furthermore, an "U" pattern between the risk and the increased coverage of cropland and grassland as well as an "inverted-U" pattern between the risk and increased coverage of shrub were observed. Conclusion: It is necessary to strengthen the scrub typhus surveillance in warm and moist areas as well as the areas with high coverage of cropland and grassland in Yunnan, and the health education in children and farmers who are at high risk.

    Context Scrub typhus is an acute febrile disease caused by Orientia tsutsugamushi. The disease can usually involve the lungs, heart, liver, spleen and brain through hematogenous dissemination. However, very rarely, acute transverse myelitis in the spinal cord develops from scrub typhus. We present a case of acute transverse myelitis following scrub typhus with a review of the literature. Findings A 66-year-old male visited a hospital for general myalgia, mild headache, and fever in October. He was noted to have thick, black papule skin on his abdomen, which was highly suggestive of scrub typhus. To confirm the diagnosis, O. tsutsugamushi antibody titers were examined and detected highly in serum by an indirect fluorescence antibody assay. Doxycycline, the standard treatment for scrub typhus, was administered. However, after seven days of treatment, he rapidly developed weakness in the right leg, paresthesia in both lower limbs, and voiding difficulty. Spinal magnetic resonance imaging (MRI) revealed lesions with high signal intensity involving the spinal cord at the thoracolumbar junction. Paraparesis gradually improved following steroid pulse therapy for five days. At one-year follow-up, he could walk without cane. Conclusions Orientia tsutsugamushi causes scrub typhus, which can affect not only the brain, but also the spinal cord. Although acute transverse myelitis develops rarely from scrub typhus, this should be considered as differential diagnosis in patients of fever with neurological deficit in endemic areas.

    Efforts to reduce adverse event rates in healthcare have revealed the importance of identifying the essential non-technical (cognitive and social) skills for safe and effective performance. Previous research on non-technical skills for operating theatre staff has concentrated on doctors rather than nursing professionals. The aim of the study was to identify the critical non-technical skills that are essential for safe and effective performance as an operating theatre scrub nurse. Experienced scrub nurses (n = 25) and consultant surgeons (n = 9) from four Scottish hospitals were interviewed using a semi-structured format. The protocols were designed to identify the main social and cognitive skills required by scrub nurses. Interviews were digitally recorded, transcribed verbatim and independently coded to extract behaviours in order to produce a list of the main non-technical skills for safe and effective scrub nurse performance. The non-technical skills of situation awareness, communication, teamwork, task management and coping with stress were identified as key to successful scrub nurse task performance. Component sets of behaviours for each of these categories were also noted. The interviews with subject matter experts from scrub nursing and surgery produced preliminary evidence that situation awareness, communication, teamwork and coping with stress are the principal non-technical skills required for effective performance as a scrub nurse.

    The pool scrubbing models were reviewed and an aerosol scrubbing code has been prepared to calculate decontamination factor through the injection zone. The developed code has been verified using the experimental results and evaluated parametrically on the input variables. In injection zone, the initial steam condensation was most effective mechanism for the aerosol removal, and the steam fraction and pool temperature were highly affected on the decontamination factor by initial steam condensation. The aerosol scrubbing code will be updated to evaluate the decontamination factor at rise zone and finally whole pool scrubber phenomena. If a severe accident occurs in a nuclear power plant (NPP), the aerosol and gaseous fission products might be produced in the reactor vessel, and then released to the environment after the containment failure. FCVS (Filtered Containment Venting System) is one of the severe accident mitigation systems for retaining the containment integrity by discharging the high-temperature and high-pressure fission products to the environment after passing through the filtration system. In general, the FCVS is categorized into two types, wet and dry types. The scrubbing pool could play an important role in the wet type FCVS because a large amount of aerosol is captured in the water pool. The pool scrubbing phenomena have been modelled and embedded in several computer codes, such as SPARC (Suppression Pool Aerosol Removal Code), BUSCA (BUbble Scrubbing Algorithm) and SUPRA (Suppression Pool Retention Analysis). These codes aim at simulating the pool scrubbing process and estimating the decontamination factors (DFs) of the radioactive aerosol and iodine gas in the water pool, which is defined as the ratio of initial mass of the specific radioactive material to final massy after passing through the water pool. The pool scrubbing models were reviewed and an aerosol scrubbing code has been prepared to calculate decontamination factor through the injection

    Full Text Available Scrub typhus is a rickettsial disease caused by Orientia tsutsugamushi, one of the most common infectious diseases in the Asia-Pacific region. It has been reported from northern, eastern, and southern India, and its presence has been documented in at least 11 Indian states. However, scrub typhus meningoencephalitis has not been well documented in Kerala. We report two cases of scrub typhus meningoencephalitis from northern Kerala. The diagnosis was made based on the clinical pictures, presence of eschar, and a positive Weil-Felix test with a titer of > 1:320. The first patient succumbed to illness due to respiratory failure and the second patient improved well.

    The involvement of the central nervous system in the form of meningitis or meningoencephalitis is common in scrub typhus and is an important differential diagnosis of other lymphocytic meningitis like tuberculous meningitis (TBM). The aim of this study was to identify the clinical and laboratory parameters that may be helpful in differentiating scrub typhus meningitis from TBM. We compared of the clinical and laboratory features of 57 patients admitted with scrub typhus meningitis or TBM during a 3-year period. Patients who had abnormal cerebrospinal fluid (CSF) and positive scrub typhus enzyme-linked immunosorbent assay serology (n=28) were included in the scrub typhus meningitis group, while the TBM group included those who satisfied the consensus diagnostic criteria of TBM (n=29). Compared with the TBM group, the mean duration of symptoms was less in patients with scrub typhus meningitis, who also had a lower magnitude of neurological deficits, such as altered mental status and cranial nerve and motor deficits. Patients with scrub typhus meningitis had a lower CSF white blood-cell count (WBC) than the TBM group (130.8±213 195±175 cells/mm 3 , P=0.002), lower CSF protein elevation (125±120 vs. 195.2±108.2mg/dl, P=0.002), and higher CSF sugar (70.1±32.4 vs. 48.7±23.4mg/dl, P=0.006). Features predictive of the diagnosis of scrub typhus meningitis included the absence of neurological impairment at presentation, blood serum glutamic-oxaloacetic transaminase>40 international units (IU)/L, serum glutamic-pyruvic transaminase>60 IU/L, total blood leukocyte count>10,000/mm 3 , CSF protein50mg/dl, CSF WBC<100 cells/mm 3 . All patients with scrub typhus meningitis recovered completely following doxycycline therapy CONCLUSIONS: This study suggests that, clinical features, including duration of fever, neurological deficits at presentation and laboratory parameters such as CSF pleocytosis,CSF protein elevation, CSF sugar levels and liver enzyme values are helpful in

  19. Estimated effects of interfacial vaporization on fission product scrubbing: Chapter 11

    Moody, F.J.; Nagy, S.G.

    1983-01-01

    When bubbles containing non-condensible gas rise through a water pool, interfacial evaporation causes a flow of vapor into the bubbles. The inflow reduces the outward particle motion toward the bubble wall, diminishing the effectiveness of fission product particle removal. This analysis provides an estimate of evaporation on pool scrubbing effectiveness. It is shown that hot gas, which boils water at the bubble wall, reduces the effective scrubbing height by less than five centimeters. Although the evaporative humidification in a rising bubble containing non-condensible gas has a diminishing effect on scrubbing mechanisms, substantial decontamination is still expected even for the limiting case of a saturated pool

    2013-01-01

    Background The Taiwan area comprises the main island of Taiwan and several small islands located off the coast of the Southern China. The eastern two-thirds of Taiwan are characterized by rugged mountains covered with tropical and subtropical vegetation. The western region of Taiwan is characterized by flat or gently rolling plains. Geographically, the Taiwan area is diverse in ecology and environment, although scrub typhus threatens local human populations. In this study, we investigate the effects of seasonal and meteorological factors on the incidence of scrub typhus infection among 10 local climate regions. The correlation between the spatial distribution of scrub typhus and cultivated forests in Taiwan, as well as the relationship between scrub typhus incidence and the population density of farm workers is examined. Methods We applied Pearson’s product moment correlation to calculate the correlation between the incidence of scrub typhus and meteorological factors among 10 local climate regions. We used the geographically weighted regression (GWR) method, a type of spatial regression that generates parameters disaggregated by the spatial units of analysis, to detail and map each regression point for the response variables of the standardized incidence ratio (SIR)-district scrub typhus. We also applied the GWR to examine the explanatory variables of types of forest-land use and farm worker density in Taiwan in 2005. Results In the Taiwan Area, scrub typhus endemic areas are located in the southeastern regions and mountainous townships of Taiwan, as well as the Pescadore, Kinmen, and Matou Islands. Among these islands and low-incidence areas in the central western and southwestern regions of Taiwan, we observed a significant correlation between scrub typhus incidence and surface temperature. No similar significant correlation was found in the endemic areas (e.g., the southeastern region and the mountainous area of Taiwan). Precipitation correlates positively

    The Arizona Nuclear Power Project (ANPP), a three-reactor site located 50 miles west of Phoenix, Arizona, has developed and implemented a program for evaluating individual chemistry technician analytical performance on a routine basis. About 45 chemistry technicians are employed at the site, 15 at each operating unit. The technicians routinely perform trace level analyses for impurities of concern to PWRs. Each month a set of blind samples is provided by an outside vendor. The blind samples contain 16 parameters which are matrixed to approximate the PWR's primary and secondary cycles. Nine technicians receive the samples, three from each operating unit, and perform the required analyses. Acceptance criteria for successful performance on the blind parameters is based on the values found in the Institute of Nuclear Power Operations (INPO) Document 83-016, Revision 2, August 1989, Chemistry Quality Control Program. The goal of the program is to have each technician demonstrate acceptable performance on each of 16 analytical parameters. On completion of each monthly set, a summary report of all of the analytical results for the sample set is prepared. From the summary report, analytical bias can be detected, technician performance is documented, and overall laboratory performance can be evaluated. The program has been very successful at satisfying the INPO requirement that the analytical performance of each individual technician should be checked on at least a six-month frequency for all important parameters measured. This paper describes the program as implemented at the Palo Verde Nuclear Generating Station and provides a summary report and trend and bias graphs for illustrative purposes

  3. Scrub typhus infection presenting as acute heart failure: A case report and systematic review of literature of cardiopulmonary involvement in scrub typhus infection

    Full Text Available We describe a middle aged previoulsy healthy female patient who presented with clinical features suggestive of acute heart failure. Investigations revealed very high NT pro-BNP, right heart enlargement, bilateral pulmonary alveolar edema and bilateral pleural effusion. In view of falling platelet counts and exudative pleural effusion inflammatory/infective causes were considered. Her Weil Felix test was strongly positive and IgM for scrub typhus also returned positive. She was started on doxycycline to which there was dramatic improvement. Thus in this case scrub typhus infection presented as acute right heart failure and the cause seemed elusive at the outset.We also systematically reviewed the existing literature on cardio-pulmonary manifestations of scrub typhus infection.

    There are an estimated one million patients with scrub typhus in the Asia-Pacific region. There are few reports describing the incidence of scrub typhus in Vietnam. Blood samples collected from 63 patients clinically diagnosed as having scrub typhus from July 2015 to September 2016 were subjected to genotyping of Orientia tsutsugamushi. Of these patients, 42 (67%) tested positive for O. tsutsugamushi, and the most common genotype was identified to be Karp (55%). Other genotypes, TA763, Gilliam type in Japan variant, and Kato were also found in 17%, 17% and 12% of patients, respectively. To better understand the epidemiological landscape of scrub typhus in Vietnam, a countrywide study is needed. LC110330-LC110333, LC110336-LC110351 and LC214804-LC214825. © The Author 2017.

    2009-10-01

    Surgical smoke is the gaseous by-product formed during surgical procedures. Most surgeons, operating theatre staff and administrators are unaware of its potential health risks. Surgical smoke is produced by various surgical instruments including those used in electrocautery, lasers, ultrasonic scalpels, high speed drills, burrs and saws. The potential risks include carbon monoxide toxicity to the patient undergoing a laparoscopic operation, pulmonary fibrosis induced by non-viable particles, and transmission of infectious diseases like human papilloma virus. Cytotoxicity and mutagenicity are other concerns. Minimisation of the production of surgical smoke and modification of any evacuation systems are possible solutions. In general, a surgical mask can provide more than 90% protection to exposure to surgical smoke; however, in most circumstances it cannot provide air-tight protection to the user. An at least N95 grade or equivalent respirator offers the best protection against surgical smoke, but whether such protection is necessary is currently unknown.

  9. Meteorological factors and risk of scrub typhus in Guangzhou, southern China, 2006–2012

    Science.gov (United States)

    2014-01-01

    Background Scrub typhus is becoming the most common vector born disease in Guangzhou, southern China. In this study, we aimed to examine the effect of weather patterns on the incidence of Scrub typhus in the subtropical city of Guangzhou for the period 2006–2012, and assist public health prevention and control measures. Methods Scrub typhus reported cases during the period of 2006–2012 in Guangzhou were obtained from National Notifiable Disease Report System (NNDRS). Simultaneous meteorological data including temperature, relative humidity, atmospheric pressure, sunshine, and rainfall were obtained from the documentation of the Guangzhou Meteorological Bureau. A negative binomial regression was used to identify the relationship between meteorological variables and scrub typhus. Results Annual incidence rates of scrub typhus from 2006 to 2012 were 3.25, 2.67, 3.81, 4.22, 4.41, 5.12, and 9.75 (per 100 000) respectively. Each 1°C rise in temperature corresponded to an increase of 14.98% (95% CI 13.65% to 16.33%) in the monthly number of scrub typhus cases, while a 1 hPa rise in atmospheric pressure corresponded to a decrease in the number of cases by 8.03% (95% CI −8.75% to −7.31%). Similarly, a 1 hour rise in sunshine corresponded to an increase of 0.17% or 0.54%, and a 1 millimeter rise in rainfall corresponded to an increase of 0.05% or 0.10%, in the monthly number of scrub typhus cases, depending on the variables considered in the model. Conclusion Our study provided evidence that climatic factors were associated with occurrence of scrub typhus in Guangzhou city, China. Temperature, duration of sunshine, and rainfall were positively associated with scrub typhus incidence, while atmospheric pressure was inversely associated with scrub typhus incidence. These findings should be considered in the prediction of future patterns of scrub typhus transmission. PMID:24620733

    A pathologic splenic rupture is rare, occurring primarily in a spleen affected by infective, hematological, and neoplastic disease. To the best of our knowledge, no prior reports of a pathologic splenic rupture due to scrub typhus exist. Intrasplenic pseudoaneurysms and focal infarctions are visible on an initial CT scan. Moreover, the spontaneous splenic rupture occurred a week later. We report a case of nontraumatic-splenic rupture in a patient with scrub typhus

    Non-technical skills are the cognitive and interpersonal behaviours that compliment clinical competence in surgery. Effective use of non-technical skills is essential for scrub practice, because they facilitate anticipation of the surgeon's requirements and promote appropriate communication behaviours. This literature review analyses the factors that may influence a scrub practitioner's use of non-technical skills during surgery. Recommendations are made that are intended to improve their use by reducing behavioural variations during surgery.

  13. Seawater scrubbing - reduction of SO{sub x} emissions from ship exhausts

    2007-07-01

    It is shown that seawater scrubbing is a promising technology for reducing sulphur oxide emissions from ships. The marine chemical aspects of shipboard seawater scrubbing have been modelled and analysed, based on a 12 MW engine burning fuel with a 3% sulphur content. Calculations have been made for different efficiencies of sulphur scrubbing, different water temperatures, and for six different water types (open ocean, Kattegatt, Baltic Proper, Bothnian Sea, Bothnian Bay, and river freshwater). The results of the calculations give the volumes of water required for (i) uptake of SO{sub x} (the scrubbing process), (ii) dilution of the scrubbing water to achieve a pH of 6.5, (iii) further dilution to achieve a pH within 0.2 units of that in the ambient water, and no more that a 1% reduction in dissolved oxygen concentration. The volumes of water required for a given efficiency of the scrubbing process increase with decreasing salinity and with increasing water temperature. The salinity dependence is non-linear, such that operation in the Bothnian Sea, Bothnian Bay and low alkalinity river freshwater would require significantly larger water volumes for scrubbing and dilution that operation in the Baltic Proper, Kattegatt or open ocean. The calculations assume access to large volumes of unaffected, ambient water. This is reasonable for a ship under way in open water, but not in enclosed or semi-enclosed waters, which would therefore require detailed case studies. It may be possible to reduce the volumes of dilution water required by, for example, aeration of the scrubbing water and addition of base to neutralise the acidic sulphur oxides. Further studies would be needed in order to assess these options

    Most scrub-shrub bird species are declining in the northeastern United States, and these declines are largely attributed to regional declines in habitat availability. American Beaver (Castor canadensis; hereafter “beaver”) populations have been increasing in the Northeast in recent decades, and beavers create scrub-shrub habitat through their dam-building and foraging activities. Few systematic studies have been conducted on the value of beaver-modified habitats for scrub-shrub birds, and these data are important for understanding habitat selection of scrub-shrub birds as well as for assessing regional habitat availability for these species. We conducted surveys in 37 beaver meadows in a 2,800-km2 study area in western Massachusetts during 2005 and 2006 to determine the extent to which these beaver-modified habitats are used by scrub-shrub birds, as well as the characteristics of beaver meadows most closely related to bird use. We modeled bird abundance in relation to microhabitat-, patch-, and landscape-context variables while adjusting for survey-specific covariates affecting detectability using N-mixture models. We found that scrub-shrub birds of regional conservation concern occupied these sites and that birds responded differently to microhabitat, patch, and landscape characteristics of beaver meadows. Generally, scrub-shrub birds increased in abundance along a gradient of increasing vegetation complexity, and three species were positively related to patch size. We conclude that these habitats can potentially play an important role in regional conservation of scrub-shrub birds and recommend that conservation priority be given to larger beaver meadows with diverse vegetation structure and composition.

  15. Advancing technician practice: Deliberations of a regulatory board.

    In 2016, the Idaho State Board of Pharmacy (U.S.) undertook a major rulemaking initiative to advance pharmacy practice by broadening the ability of pharmacists to delegate tasks to pharmacy technicians. The new rules of the Board thus moved the locus of control in technician scope of practice from law to pharmacist delegation. Pharmacist delegation is individualistic and takes into account the individual technician's capabilities, the pharmacist's comfort level, facility policies, and the risk mitigation strategies present at the facility, among other factors. State law limits, by contrast, are rigid and can mean that pharmacists are unable to delegate tasks that are or could otherwise be within the abilities of their technicians. The expanded technician duties are in two domains: 1) medication dispensing support (e.g., tech-check-tech, accepting verbal prescriptions, transferring prescriptions, and performing remote data entry); and 2) technical support for pharmacist clinical services (e.g., administering immunizations). This commentary reviews the evidence behind these expanded duties, as well as the key regulatory decision points for each task. The Board's rules and approach may prove useful to other states and even other governing bodies outside the U.S. as they consider similar issues. Copyright © 2017 Elsevier Inc. All rights reserved.

    In view of the known health hazards of x-ray radiation, this study focuses on the basic hematological parameters: red blood cells (RBCs), white blood cells (WBCs) and platelets count in x-ray technicians. The aim was to identify the affect of x-ray radiation on blood cell counts in x-ray technicians. The present study was conducted in the Department of Physiology, College of Medicine, King Saud University, Riyadh, Kingdom of Saudi Arabia during the year 2002. In this study, a group of 40 apparently healthy male x-ray technicians with age ranging from 25-50-years were recruited. They were matched with another group of 40 apparently healthy control subjects in terms of age, sex and ethnic origin. Both groups met with exclusion criteria as per standard. Red blood cells, WBC and platelets count were performed by using a blood cell auto analyser. The mean value of platelet count was significantly decreased (p<0.01) in x-ray technicians when compared to controls. However, no significant difference was observed in RBC and WBC count between the groups. Radiation causes decreased platelet count. Further, studies are needed to study the long-term effects of x-ray radiation on blood cell count in x-ray technicians. (author)

    Climate change, by its influence on the ecology of vectors might affect the occurrence of vector-borne diseases. This study examines the effects of meteorological factors in Japan on the occurrence of scrub typhus, a mite-borne zoonosis caused by Orientia tsutsugamushi. Using negative binomial regression, we analysed the relationships between meteorological factors (including temperature, rainfall, snowfall) and spring-early summer cases of scrub typhus in Yamagata Prefecture, Japan, during 1984-2014. The average temperature in July and August of the previous year, cumulative rainfall in September of the previous year, snowfall throughout the winter, and maximum depth of snow cover in January and February were positively correlated with the number of scrub typhus cases. By contrast, cumulative rainfall in July of the previous year showed a negative relationship to the number of cases. These associations can be explained by the life-cycle of Leptotrombidium pallidum, a predominant vector of spring-early summer cases of scrub typhus in northern Japan. Our findings show that several meteorological factors are useful to estimate the number of scrub typhus cases before the endemic period. They are applicable to establish an early warning system for scrub typhus in northern Japan.

    The aim of this study was to identify risk factors associated with severe scrub typhus, in order to provide a reference for clinical decision-making. A case-control study was conducted of scrub typhus patients who presented at local hospitals between 2010 and 2013. In total, 46 patients with severe scrub typhus complications (cases) and 194 without severe complications (controls) were included. There were significant differences in the duration of illness before effective antibiotic therapy, lymphadenopathy, rash, blood platelet count, white blood cell (WBC) count, percentage neutrophils, and percentage lymphocytes between the case and control groups. Multivariate analysis demonstrated that the following four factors were significantly associated with the severe complications of scrub typhus: (1) duration of illness before effective antibiotic therapy (odds ratio (OR) 2.287, 95% confidence interval (CI) 1.096-4.770); (2) the presence of a rash (OR 3.694, 95% CI 1.300-10.495); (3) lymphadenopathy (OR 2.438, 95% CI 1.090-5.458); (4) blood platelet count scrub typhus. When scrub typhus patients present with a rash, lymphadenopathy, or blood platelet count <100×10(9)/l, clinicians should be alert to the appearance of severe complications.

    Full Text Available Orientia tsutsugamushi, the etiologic agent of scrub typhus, is a mite-borne rickettsia transmitted by the parasitic larval stage of trombiculid mites. Approximately one-third of the world's population is at risk of infection with Orientia tsutsugamushi, emphasizing its importance in global health. In order to study scrub typhus, Orientia tsutsugamushi Karp strain has been used extensively in mouse studies with various inoculation strategies and little success in inducing disease progression similar to that of human scrub typhus. The objective of this project was to develop a disease model with pathology and target cells similar to those of severe human scrub typhus. This study reports an intravenous infection model of scrub typhus in C57BL/6 mice. This mouse strain was susceptible to intravenous challenge, and lethal infection occurred after intravenous inoculation of 1.25 × 10(6 focus (FFU forming units. Signs of illness in lethally infected mice appeared on day 6 with death occurring ∼ 6 days later. Immunohistochemical staining for Orientia antigens demonstrated extensive endothelial infection, most notably in the lungs and brain. Histopathological analysis revealed cerebral perivascular, lymphohistiocytic infiltrates, focal hemorrhages, meningoencephalitis, and interstitial pneumonia. Disseminated infection of endothelial cells with Orientia in C57BL/6 mice resulted in pathology resembling that of human scrub typhus. The use of this model will allow detailed characterization of the mechanisms of immunity to and pathogenesis of O. tsutsugamushi infection.

    Scrub typhus is a well-known acute febrile illness caused by Orientia tsutsugamushi. This disease has multiorgan involvement, which includes the lungs, heart, liver, spleen, and the central or peripheral nervous system. Scrub typhus involving the central nervous system (CNS) is not rare. However, meningitis and meningoencephalitis can cause changes in mentation and death and are therefore associated with a poor prognosis. We report two consecutive cases of scrub typhus with CNS involvement. One patient presented with extensive white matter involvement, similar to that observed in acute disseminated encephalomyelitis, whereas the other patient presented with subependymal enhancement along the lateral ventricles. To the best of our knowledge, scrub typhus encephalitis, with extensive white matter involvement and subependymal enhancement, are very rarely described findings in the previous literature. Our patients did not show complete recovery, but the symptoms resolved with treatment. Recognizing these uncommon radiologic findings of scrub typhus may be helpful in the early diagnosis of scrub typhus with CNS involvement, which may alter the prognoses of patients.

  2. Flotability Improvement of Ilmenite Using Attrition-Scrubbing as a Pretreatment Method

    2017-01-01

    Full Text Available Flotation technology of the recovery and utilization of ilmenite from tailings of iron beneficiated in Panzhihua was investigated based on mineralogical study. The results of mineralogical study show that the main occurrence of the valuable mineral are liberated grains of ilmenite. Experimental results of flotation conditions show that attrition-scrubbing raw ores exhibit good flotability with higher recoveries and a slight decrease in grade compared to ores without attrition-scrubbing. Further, open-circuit experiments also prove the superiority of attrition-scrubbing raw ores. The results of closed-circuit experiments show that qualified ilmenite concentrate can be obtained and the yield, grade, and recovery are 22.26%, 47.06%, and 60.73%, respectively. Theoretical study and analysis show that there are two contributions to superior flotability for attrition-scrubbing samples. The first is that the attrition-scrubbing samples can uncover more ferrous ions on the newly-produced fresh ilmenite surface, resulting in the increase in active sites. The other is that in the process of attrition-scrubbing, the transformation of ferrous ions to ferric ions can be promoted.

    In South Korea, scrub typhus is the most common acute febrile illness in autumn. We analyzed scrub typhus cases reported from 2008 to 2012 to describe the epidemiology of scrub typhus as well as eschar patterns. A total of 30,478 cases were reported from 2008 to 2012; the incidence rates were higher in the southern and western regions of South Korea. The common clinical symptoms of confirmed scrub typhus cases from 2010 to 2012 were fever/chills (95.2%), eschars (78.9%), and myalgia (61.7%). The primary sites of eschars were the lower extremities (19.0%), abdomen/waist (13.4%), and axilla (11.5%) in men and the shoulder/frontal chest (15.1%), lower extremities (14.5%), and abdomen/waist (13.6%) in women. Regardless of gender, eschars tended to be more on the lower extremities among the leisure activities group. Among the occupational farm work group, who usually lived in rural areas, eschars appeared most frequently on the abdomen/waist in men and on the shoulder/frontal chest in women. Eschar patterns were influenced by gender and activities. These results could facilitate the prevention of scrub typhus and clarify the current status of scrub typhus in South Korea.

  4. Epidemiology of aplastic anemia in Japanese radiological technicians

    1976-01-01

    Among Japanese radiological technicians, four deaths from aplastic anemia have been recorded. Based on this fact, some epidemiological considerations are tried. During the period from 1930 to 1960, the population of radiological technicians is estimated to be 74,400 man-years, in which 0.5 aplastic anemias are expected. However actually three died from aplastic anemia. This difference is statistically significant at the 1% level. On the other hand, in the period from 1961 to 1973, the observed value is 1 against 0.7 expected. It is concluded that aplastic anemia had been frequently induced among Japanese radiological technicians in the era when there was much exposure to occupational radiation. (auth.)

  5. Radiological Control Technician: Phase 4, Facility practical training attachment

    International Nuclear Information System (INIS)

    1992-10-01

    At DOE sites with more than one facility, and where RCT tasks at each facility may differ, site and facility tasks should be separated. The tasks that are common to all the facilities on the site should be included in Phase II training with the core tasks. Tasks unique to a facility should be added to the training program qualification standard, as an attachment, as Phase IV training. Not all the DOE sites will include Phase IV training in their programs. Phase IV training allows each site to qualify technicians to a select facility. Since the core training for the technicians is standardized, the transfer of technicians between facilities requires that only facility tasks be taught, provided the core qualification is current

  6. ASHP statement on the pharmacy technician's role in pharmacy informatics.

    Science.gov (United States)

    2014-02-01

    The American Society of Health- System Pharmacists (ASHP) believes that specially trained pharmacy technicians can assume important supportive roles in pharmacy informatics. These roles include automation and technology systems management, management of projects, training and education, policy and governance, customer service, charge integrity, and reporting. Such roles require pharmacy technicians to gain expertise in information technology (IT) systems, including knowledge of interfaces, computer management techniques, problem resolution, and database maintenance. This knowledge could be acquired through specialized training or experience in a health science or allied scientific field (e.g., health informatics). With appropriate safeguards and supervision, pharmacy technician informaticists (PTIs) will manage IT processes in health-system pharmacy services, ensuring a safe and efficient medication-use process.

    Dental laboratory technicians are at risk of developing occupational respiratory diseases due to exposure to various potentially toxic substances in their working environment. Since 1939, few cases of silicosis among dental technician have been reported. We illustrate a 38 year-old female, who worked in a dental laboratory for 20 years, initially treated as pulmonary tuberculosis and chronic necrotising aspergillosis without much improvement. Computed tomography guided lung biopsy and bronchoscopic transbronchial lung biopsy were performed. Lung tissue biopsies showed presence of refractile dental materials within the areas of histiocyte proliferation. The diagnosis of dental technician pneumoconiosis was obtained and our patient underwent pulmonary rehabilitation. This case highlights the importance of obtaining a detailed occupational history in tuberculosis endemic area, as pulmonary tuberculosis is a great mimicker of other respiratory diseases.

    Two methods were used to collect blood from the jugular vein of dogs. In both techniques, only one technician was required. A rope with a slip knot was placed around the base of the neck to assist in restraint and act as a tourniquet for the vein. The technician used one hand to restrain the dog by the muzzle and position the head. The other hand was used for collecting the sample. One of the methods could be accomplished with the dog in its cage. The bleeding techniques were rapid, requiring approximately 1 minute per dog.

    Scrub typhus is rampant in northern, eastern, and southern India. Central nervous system involvement in the form of meningitis or meningoencephalitis is common in scrub typhus. As specific laboratory methods remain inadequate or inaccessible in developing countries, prompt diagnosis is often difficult. The aim of this study was to characterize neurological complications in scrub typhus from northeastern region of India. We did a prospective study of scrub meningoencephalitis at North Eastern Indira Gandhi Regional Institute of Medical Sciences among patients admitted to hospital between October 2009 and November 2011. The diagnosis was made based on the clinical pictures, presence of an eschar, and a positive Weil-Felix test (WFT) with a titer of >1:160 and if required a positive scrub IgM enzyme-linked immunosorbent assay. Lumbar puncture was performed in patients with headache, nuchal rigidity, altered sensorium or cranial nerve deficits, and magnetic resonance imaging (MRI) brain performed if needed. Twenty-three patients of scrub typhus meningitis that were serologically confirmed were included in the study. There were 13 males and 10 females. Fever ≥1 week was the most common manifestation (39.1%). Interestingly, none had an eschar. Median cerebrospinal fluid (CSF) cell count, lymphocyte percentage, CSF protein, CSF glucose/blood glucose, CSF ADA were 17 cells/μL, 90%, 86 mg/dL, 0.6605 and 3.6 U/mL, respectively. All patients were treated with doxycycline. There was no mortality in our study. Absence of Eschar does not rule out scrub typhus. Clinical features and CSF findings can mimic tuberculous meningitis so misdiagnosis may lead to unwarranted prolonged empirical antituberculous therapy in cases of lymphocytic meningoencephalitis. Delay in treatment can be potentially fatal. WFT still serves as a useful and affordable diagnostic tool for this disease in resource-poor countries.

    Full Text Available Scrub typhus, a bacterial infection caused by Orientia tsutsugamushi, is increasingly recognized as an important cause of fever in Asia, with an estimated one million infections occurring each year. Limited access to health care and the disease's non-specific symptoms mean that many patients are undiagnosed and untreated, but the mortality from untreated scrub typhus is unknown. This review systematically summarizes the literature on the untreated mortality from scrub typhus and disease outcomes.A literature search was performed to identify patient series containing untreated patients. Patients were included if they were symptomatic and had a clinical or laboratory diagnosis of scrub typhus and excluded if they were treated with antibiotics.

    Scrub typhus is rare in pregnancy, but it has now become an important cause of febrile illness in pregnancy in sub-Himalayan region of India. Only a few case reports have been published so far, and they show adverse maternal and fetal outcomes. No consensus has been reached till now regarding treatment. All the pregnant patients irrespective of period of gestation admitted with febrile illness with positive IgM ELISA for scrub typhus with or without eschar were included. The clinical profile was observed using a detailed history of symptoms, travel, recreation, agricultural activities, treatment record prior to admission, and a detailed examination, and the treatment outcome was noted. Fever workup including cultures, CXR, CSF analysis, serology for scrub was done. IgM scrub typhus was done by kit method manufactured by InBios Intertational, Inc. We observed in total 14 pregnant patients out of which eight were in the the second trimester and six were in the third trimester. The clinical features of the disease observed for pregnant females were the same as for nonpregnant females. There was no difference in the severity of scrub typhus between pregnant and nonpregnant women. No mortality was found in these patients. On follow-up, they had normal peripartum and postpartum periods. All were treated with azithromycin 500 mg once a day for 5 days. Although rare, scrub typhus should be considered in differential diagnosis of fever in pregnant patients especially in scrub season. Azithromycin should be the drug of choice in pregnancy as it has no adverse effect on fetus and pregnancy outcome.

    Scrub typhus is known as a self-limited infectious disease. Cardiac complication is uncommon and usually not life-threatening. Until now, few cases of fulminant myocarditis by scrub typhus have been reported. So, we investigated incidence and predictors of acute myocarditis in severe scrub typhus. We retrospectively reviewed 89 patients among 91 scrub typhus confirmed patients who examined an echocardiogram and cardiac biomarkers from 2005 to 2015 in the intensive care unit at our hospital. We excluded two patients who didn't have electrocardiography. Patients were divided into two groups and compared between scrub typhus with (n = 13) and without (n = 76) acute myocarditis. Age, sex, and underlying diseases were similar between the groups. The existence of eschar and duration of general ache and fever were similar between the groups. However, patients with acute myocarditis had more elevated total bilirubin, high incidence of ST elevations and paroxysmal atrial fibrillation (PAF) than those without acute myocarditis. Receiver operating characteristic analysis showed that the PAF was a predictor of myocarditis with a sensitivity of 70% and specificity of 84%. Predictive power of combination of ST-segment elevation and PAF was significantly associated with myocarditis in the multivariate analysis (odds ratio, 1.57; 95% confidence interval [CI], 1.21 to 11.7; p = 0.041) and area under the curve was 0.947 (95% CI, 0.878 to 0.983; p scrub typhus may be more common than previously reported. Patients with high bilirubin and PAF are at increased risk of acute myocarditis with scrub typhus. These patients warrant closer follow-up and echocardiogram would be needed.

    Controlling scrub encroachment is a major challenge for conservation management on chalk grasslands. However, direct comparisons of scrub removal methods have seldom been investigated, particularly at the landscape scale. Effective monitoring of grassland scrub is problematic as it requires simultaneous information on large scale patterns in scrub cover and fine-scale changes in the grassland community. This study addressed this by combining analysis of aerial imagery with rapid field surveys in order to compare the effectiveness of four scrub management strategies on Defence Training Estate Salisbury Plain, UK. Study plots were sited within areas undergoing management and in unmanaged controls. Controls showed dramatic increases in scrub cover, with encroachment of a mean 1096 m(2) per hectare over ten years. Whilst all management strategies were effective in reducing scrub encroachment, they differed in their ability to influence regeneration of scrub and grassland quality. There was a general trend, evident in both the floral community and scrub levels, of increased effectiveness with increasing management intensity. The dual methodology proved highly effective, allowing rapid collection of data over a range of variables and spatial scales unavailable to each method individually. The methodology thus demonstrates potential for a useful monitoring tool. Copyright © 2011 Elsevier Ltd. All rights reserved.

  8. Technologies and policies for "hard to scrub" emissions sources

    Science.gov (United States)

    Friedmann, J.

    2016-12-01

    The science of climate change yields harsh math regarding atmospheric accumulations of GHGs. The world is far from target trajectories for 2C or 1.5C, and the global carbon budget is severe. To achieve those targets requires two things. First, we must field technologies that reduce emissions from the "hard to scrub" parts of the US and global economies, such as heavy industry (cement and steel), aviation, ocean shipping, and household cooking and heating. Second, we will likely need negative emissions pathways for those sources that prove extremely difficult to remove or reduce - the climate equivalent of adding revenue to one's budget. Such pathways may well need to convert GHG emissions (especially CO2 and methane) into useful products with minimal infrastructure builds. Dramatic advances in advanced manufacturing, 3D printing, simulation, modeling, and data analytics have made possible solutions which were previously unthinkable or impossible. This include "bespoke reactors", which can simultaneously perform separations and conversions; low-cost modular chemical systems of any scale; biologically inspired or biologically mediated energy services; direct air carbon-capture systems; and electrochemical pathways for emissions reduction and conversion. However, these approaches are unlikely to be fielded without policy actions or reforms that support such systems in competitive global energy markets. Such policy measures do NOT require a carbon price. Rather, they could include individual or combined measures such as emission or performance standards, financial incentives (like tax credits or low-cost access to capital), border adjustable tariffs, creation of CO2 utilities, ands public good surcharges. Innovation in both technical and policy arenas are needed to achieve the goals of the Paris agreement signatories, and these innovations can be simultaneously configured to deliver substantive greenhouse gas mitigation.

  9. Science and engineering technicians in the United States: characteristics of a redefined population, 1972

    International Nuclear Information System (INIS)

    Finn, M.G.

    1978-02-01

    The 1972 redefined population was distributed among 10 technician fields. Approximately 75% of the total were concentrated in four relatively large fields: computer programmers; draftsmen; electrical and electronic technicians; and technicians, other fields. Women accounted for 11% of all technicians. The average age of technicians in 1972 was 37. Whites comprised 94.8% of all technicians, while 3.0% were black. More technicians resided in the middle Atlantic region than in any other region. As a percentage of the civilian labor force, however, technicians were most heavily concentrated in the New England and mountain regions. The educational level of technicians was quite diverse: about one-third had no postsecondary education, about one-sixth had at least a bachelor's degree. About one-half fell somewhere between these extremes. Approximately 68% of all technicians reported some form of supplemental training outside formal educational institutions. This training was quite diverse. In 1972, unemployed technicians totaled 3.2% of the technician labor force. Fourteen percent of technicians reported employment outside their field, and 11% reported employment outside the 10 technician fields that constituted the focus of this report. The median annual earnings of technicians employed full-time in 1971 was approximately $10,400. Private companies employed 71% of the technicians; federal and state governments employed 12.4% and 7.4%, respectively. Most other technicians were employed by local government or nonprofit organizations. Implications for policy and planning are drawn. The statistics presented here indicate that the most commonly used assumptions about education--occupation linkages are grossly oversimplified. 5 figures, 44 tables

  10. Scrub typhus re-emergence in India: Contributing factors and way forward.

    Science.gov (United States)

    Ranjan, Jai; Prakash, John Antony Jude

    2018-06-01

    Scrub typhus is a mite borne infectious disease which has re-emerged in India in the 3rd millennium after years of quiescence. In this review, the authors hypothesize the various factors responsible for resurgence of this disease. The main drivers that could have contributed to the upsurge in scrub typhus cases in past two decades are changes in land use land cover (LULC) and urbanisation which are; as a result of the population explosion, causing a strain on sanitation and also increased diversion of forest land for agricultural use. In addition, the availability of better tests, changes in antimicrobial use, climate change also could have impacted the epidemiology, which is showing an upward trend as is evidenced by increasing reports and concomitant publications from India on scrub typhus. Scrub typhus cases are supposed to increase in the coming years as factors like global warming, urbanisation, changes in LULC and rise in AMR (anti-microbial resistance) will be difficult or impossible to control. Therefore, increasing awareness of public and health care professionals regarding scrub typhus coupled with availability of rapid diagnostic assays and implementation of appropriate treatment protocols for control of AFI (acute febrile illness) especially at the community level will help mitigate the scenario in the long run.

    Lee, Min; Kim, June; Jo, Dae Sun

    2017-04-01

    Chloramphenicol and tetracycline are not recommended for treating scrub typhus in pediatric patients because of potential side effects, such as aplastic anemia or tooth discoloration. While clarithromycin has recently been used in adults, few reports have been published on its effects in pediatric patients. We report the clinical profiles of pediatric scrub typhus and the effects of clarithromycin on scrub typhus in children. We retrospectively analyzed medical records of 56 children with scrub typhus who were admitted between 2004 and 2013 to Chonbuk National University Hospital, Jeonju, Korea. Cases were divided into 3 groups based on thetreatment drug (chloramphenicol, azithromycin, and clarithromycin). We compared their clinical manifestations and laboratory findings. All patients exhibited fever and rash. Other common clinical manifestations were eschars (66%), lymphadenopathy (48%), upper respiratory symptoms (42%), abdominal pain (32%), and hepatosplenomegaly (14%). Elevated levels of C-reactive protein, erythrocyte sedimentation rates, aspartate transaminase, and alanine transaminase were detected in 95%, 96%, 84%, and 77% of patients, respectively. Additionally, decreased platelet and white blood cell levels were observed in 43% and 36% of patients, respectively. There were no statistical differences between the treatment groups in mean age ( P =0.114) or sex ( P =0.507). However, time to defervescence after the treatments differed significantly, being the shortest in the clarithromycin group ( P =0.019). All patients recovered without complications related to the disease or drugs. Clarithromycin was as effective as chloramphenicol and azithromycin in pediatric scrub typhus patients and may be used as a first-line treatment drug.

    1982-08-01

    Soil decontamination tests were done using three scrubbing solutions on five different transuranic-contaminated soils from Department of Energy sites. The soils came from Rocky Flats, Colorado; Hanford, Washington; Mound Facility, Ohio; Idaho National Engineering Laboratory, Idaho; and Los Alamos National Laboratory, New Mexico. Decontamination was effected by physical and chemical means. A pH 12.5 scrub effected decontamination by serving as a hydraulic grading and attrition scrub medium; this solution did not solubilize the actinide contamination. A 2% HNO 3 , 0.2% HF, 2% pine oil, and 5% Calgon solution effected decontamination by physical and chemical means; this solution solubilized particulate actinide and actinide dispersed on the surface of soil particles. A 2N HCl scrub was also used to effect decontamination by physical and chemical means; this reagent solubilized soil constituents, removing contamination that had migrated into mineral surfaces. Only Rocky Flats soil was effectively decontaminated by the high pH solution although all soils had an enrichment of the activity in the -150 mesh fraction. Attrition scrubbing with both acid solutions had a better decontamination ability for the +150 mesh fraction for Hanford, INEL, and LANL soils. In addition, the acid solutions solubilized some of the plutonium and had a decontamination effect on the fine fractions

    It is demonstrated that exposing the VOC air streams to the electro-scrubbing reactor with a gas diffusion electrode leads to an efficient removal of organics. The importance order of the influence factors on the electro-scrubbing reactor performance is: conductivity, voltage and air stream flow-rate. The effective conductivity and high voltages generally are beneficial to the removal process and the air flow-rate is not a significant factor compared with the other two, indicating that the reactor might have a consistently satisfying performance within a wide range of gas volumetric load. The mass transfer of both organics and oxygen in the reactor is estimated by mathematical model, and the calculation determines the concentration boundary conditions for the 2-ethoxyethyl acetate removal: if the 2-ethoxyethyl acetate concentration in the inflow air stream holds C{sub G,i} {<=} 0.7198 % , the removal in the electro-scrubbing reactor is electrochemical reaction controlled; if C{sub G,i} > 0.7198 % , the controlling step will be the oxygen mass transfer from the air to the liquid in the electro-scrubbing reactor. The Apparent Current Efficiency of the electro-scrubbing reactor was also determined using COD data, which is significantly higher than some commercial metal oxide electrodes, showing that the reactor is energy efficient and has the promise for the future scale-up.

  14. A new standard for multidisciplinary health and safety technicians

    Over the last two decades, a significant trend in health and safety has been toward greater specialization. However, compartmentalization of health and safety disciplines often leads to an inequity in resources, especially when appropriations overemphasize one risk to the detriment of others. For example, overemphasis on radiological safety can create an imbalance in overall worker protection. A multidisciplinary technical can help restore the balance and provide for a healthier and safer work environment. The key advantages of a multidisciplinary health and safety technician include: Broad coverage of the work area by one technician, More diverse use of the technician pool, Better coverage for off-shift or nonstandard hours, Balance of risks because all hazards are considered, Integrated emergency response, Ownership, Less time of identify the correct person with the requisite skills. We have developed a new standard that establishes the training and related qualifications for a multidisciplinary health and safety technician. The areas of training and qualification that are addressed include elements of industrial hygiene, industrial safety, fire protection, electrical safety, construction safety, and radiation safety. The initial core training program ensures that individuals are trained to the performance of requirements of the job. Initial training is in five areas: Fundamentals, Hazard recognition, Hazard assessment, Hazards controls, Hazards minimization.

    The overall goal of this project has been to develop curricula, certification requirements, and accreditation standards for training on energy efficient practices and technologies for commercial building technicians. These training products will advance industry expertise towards net-zero energy commercial building goals and will result in a substantial reduction in energy use. The ultimate objective is to develop a workforce that can bring existing commercial buildings up to their energy performance potential and ensure that new commercial buildings do not fall below their expected optimal level of performance. Commercial building equipment technicians participating in this training program will learn how to best operate commercial buildings to ensure they reach their expected energy performance level. The training is a combination of classroom, online and on-site lessons. The Texas Engineering Extension Service (TEEX) developed curricula using subject matter and adult learning experts to ensure the training meets certification requirements and accreditation standards for training these technicians. The training targets a specific climate zone to meets the needs, specialized expertise, and perspectives of the commercial building equipment technicians in that zone. The combination of efficient operations and advanced design will improve the internal built environment of a commercial building by increasing comfort and safety, while reducing energy use and environmental impact. Properly trained technicians will ensure equipment operates at design specifications. A second impact is a more highly trained workforce that is better equipped to obtain employment. Organizations that contributed to the development of the training program include TEEX and the Texas Engineering Experiment Station (TEES) (both members of The Texas A&M University System). TEES is also a member of the Building Commissioning Association. This report includes a description of the project

    The implementation and outcomes of a pharmacy technician medication history program are described. An interprofessional medication reconciliation team, led by a clinical pharmacist and a clinical nurse specialist, was charged with implementing a new electronic medication reconciliation system to improve compliance with medication reconciliation at discharge and capture compliance-linked reimbursement. The team recommended that the pharmacy department be allocated new pharmacy technician full-time-equivalent positions to assume ownership of the medication history process. Concurrent with the implementation of this program, a medication history standard was developed to define rules for documentation of what a patient reports he or she is actually taking. The standard requires a structured interview with the patient or caregiver and validation with outside sources as indicated to determine which medications to document in the medication history. The standard is based on four medication administration category rules: scheduled, as-needed, short-term, and discontinued medications. The medication history standard forms the core of the medication history technician training and accountability program. Pharmacy technicians are supervised by pharmacists, using a defined accountability plan based on a set of medical staff approved rules for what medications comprise a best possible medication history. Medication history accuracy and completeness rates have been consistently over 90% and rates of provider compliance with medication reconciliation rose from under 20% to 100% since program implementation. A defined medication history based on a medication history standard served as an effective foundation for a pharmacy technician medication history program, which helped improve provider compliance with discharge medication reconciliation.

    2000-01-01

    Over the last two decades, a significant trend in health and safety has been toward greater specialization. However, compartmentalization of health and safety disciplines often leads to an inequity in resources, especially when appropriations overemphasize one risk to the detriment of others. For example, overemphasis on radiological safety can create an imbalance in overall worker protection. A multidisciplinary technical can help restore the balance and provide for a healthier and safer work environment. The key advantages of a multidisciplinary health and safety technician include: Broad coverage of the work area by one technician, More diverse use of the technician pool, Better coverage for off-shift or nonstandard hours, Balance of risks because all hazards are considered, Integrated emergency response, Ownership, Less time of identify the correct person with the requisite skills. We have developed a new standard that establishes the training and related qualifications for a multidisciplinary health and safety technician. The areas of training and qualification that are addressed include elements of industrial hygiene, industrial safety, fire protection, electrical safety, construction safety, and radiation safety. The initial core training program ensures that individuals are trained to the performance of requirements of the job. Initial training is in five areas: Fundamentals, Hazard recognition, Hazard assessment, Hazards controls, Hazards minimization. Core training is followed by formal qualification on specific tasks, including ventilation surveys, air monitoring, noise assessments, radiological monitoring, area inspections, work-area setups, and work coverage. The new standard addresses not only training topics and requirements, but also guidance to ensure that performance objectives are met.

    During urological surgical procedures with fluoroscopy, the doses of the care team may be significant. However, the knowledge of the occupational exposure of these professionals is still very incipient in the national surgical centers. The objective of the study is to determine the isodose curves of the urological surgical procedures, in order to estimate the exposure of the personnel involved. The equipment used was a Arco-C BV Philips Bracelet. Patients with thicknesses of 20 and 28 cm were simulated using acrylic plates. The dose rates were measured with RaySafe i2 Unfors dosimeters positioned in a 50 x 50 cm mesh at three different heights of the floor: 95, 125 and 165 centimeters respectively corresponding to the gonadal, thoracic and crystalline regions of a typical adult . The isodose curves applied to the distribution of the surgical team suggest that the exposures are in the following descending order of intensity: primary physician, auxiliary physician, scrub nurse, anesthetist and nurse

    Full Text Available A study on bionomics of scrub typhus vector and its host species was conducted in a transmigration scheme of Kumpeh, Jambi, Sumatera. Ten species of trombiculid mites were collected from 6 species of rats and 2 species of squirrels. Leptotrombidium (L. deliense, a known vectorof scrub typhus vector elsewhere, was found mostly on Rattus tiomanicus. This rat species was widely distributed in forest, disturbed land and cultivated land habitations found in the study area. Chigger infestations on R. tioma­nicus trapped in disturbed land were 63.6% — 81.8%. The average number of chigger collected from disturbed land was highest in December, from forest habitation was in October and from the cultivated land habitation was in November. Rattus tiomanicus was found to be a potential rat species for main­taining the natural cycle of scrub typhus in the study area.

    The ToF Detector of the CBM Experiment will be equipped with FPGA-based read-out boards (ROBs). These ROBs will be operated in a radiation environment, and therefore need a mitigation mechanism against soft errors in the SRAM-based configuration memories of the FPGAs. The proposed approach combines intrinsic on-chip single upset correction with extrinsic selective frame scrubbing for multiple-bit upsets. The slow control is realized using the GBT-SCA, which is capable of handling interrupts. This enables the new approach of event-driven configuration frame correction. While conventional blind scrubbing leads to a continuous load on the control path, the selective frame scrubbing reduces this load to a minimum. For verification purposes, radiation tests with a proton beam were performed at COSY, Juelich. The occurred soft errors were classified into single and multiple- bit upsets, enabling an estimation of the rate at which extrinsic intervention is necessary.

    The Savannah River National Laboratory (SRNL) prepared approximately 240 gallons of Caustic-Side Solvent Extraction (CSSX) solvent for use at the Salt Waste Processing Facility (SWPF). An Extraction, Scrub, and Strip (ESS) test was performed on a sample of the prepared solvent using a salt solution prepared by Parsons to determine cesium distribution ratios (D(Cs)), and cesium concentration in the strip effluent (SE) and decontaminated salt solution (DSS) streams. This data will be used by Parsons to help qualify the solvent for use at the SWPF. The ESS test showed acceptable performance of the solvent for extraction, scrub, and strip operations. The extraction D(Cs) measured 15.5, exceeding the required value of 8. This value is consistent with results from previous ESS tests using similar solvent formulations. Similarly, scrub and strip cesium distribution ratios fell within acceptable ranges.

    The article reviews some commonly used orthodontic treatments as well as new strategies to assist in the correction of malocclusion. Many techniques are used in conjunction with surgical intervention and are a necessary compliment to orthognathic surgery. Basic knowledge of these practices will aid in the surgeon's ability to adequately treat the patient. Many orthodontists and surgeons are eliminating presurgical orthodontics to adopt a strategy of 'surgery first' orthodontics in orthognathic surgery. This has the benefit of immediate improvement in facial aesthetics and shorter treatment times. The advent of virtual surgical planning has helped facilitate the development of this new paradigm by making surgical planning faster and easier. Furthermore, using intraoperative surgical navigation is improving overall precision and outcomes. A variety of surgical and nonsurgical treatments may be employed in the treatment of malocclusion. It is important to be familiar with all options available and tailor the patient's treatment plan accordingly. Surgery-first orthodontics, intraoperative surgical navigation, virtual surgical planning, and 3D printing are evolving new techniques that are producing shorter treatment times and subsequently improving patient satisfaction without sacrificing long-term stability.

    Scrub typhus is a re-emerging mite-borne rickettsiosis, which continues to be underdiagnosed, with lethal consequences. The present study was conducted to determine the seasonality, clinical presentation and predictors of mortality in patients with scrub typhus at a tertiary care teaching hospital in northern India. Scrub typhus was suspected in patients attending the hospital as per the standard case definition and serological evidence was obtained by performing an IgM ELISA. A total of 284 patients with scrub typhus from urban and rural areas were seen, predominantly from July to November. The most common clinical presentation was a bilateral community-acquired pneumonia (CAP), which resembled pneumonia due to atypical pathogens and often progressed to acute respiratory distress syndrome (ARDS). An acute undifferentiated febrile illness (AUFI) or a febrile illness associated with altered sensorium, aseptic meningitis, shock, abdominal pain, gastrointestinal bleeding or jaundice was also seen. Eschars were seen in 17 per cent of patients, and thrombocytopenia, transaminitis and azotaemia were frequent. There were 24 deaths (8.5%) caused predominantly by ARDS and multi-organ dysfunction. The mortality in patients with ARDS was high (37%). ARDS [odds ratio (OR)=38.29, 95% confidence interval (CI): 9.93, 147.71] and acute kidney injury (OR=8.30, 95% CI: 2.21, 31.21) were the major predictors of death. The present findings indicate that scrub typhus may be considered a cause of CAP, ARDS, AUFI or a febrile illness with multisystem involvement, in Uttarakhand and Uttar Pradesh, especially from July to November. Empiric therapy of CAP may include doxycycline or azithromycin to ensure coverage of underlying unsuspected scrub typhus.

    To study the clinical and laboratory profile of pediatric scrub typhus in rural south India. This is a descriptive study of the clinical and laboratory features of 117 children with IgM ELISA proven scrub typhus out of 448 children, who were admitted in the Pediatric ward of a tertiary care hospital, during the study period of November 2014 through March 2015. Fever was present in all 117 children, with mean duration of fever at admission as 9 d. Gastrointestinal tract was the most commonly affected system, seen in 51 % of children. Cough (82 %), myalgia (70 %), vomiting (68 %), headache (45 %) and pain abdomen (42 %) were the most common symptoms of scrub typhus. Hepatomegaly (70), splenomegaly (53 %), pallor (50 %) and eschar (41 %) were the common clinical findings in children with scrub typhus. Out of 49 children with eschar, 32 were associated with regional lymphadenopathy, which was commonly seen in axillary, neck and groin regions. Leucocytosis (50 %), anemia (56 %), increased SGOT / SGPT (47 %), thrombocytopenia (41 %), hypoalbuminemia (40 %) and hyponatremia (40 %) were the common lab features. Shock (46 %), myocarditis (24 %) and pneumonia (16 %) were the common complications seen in these children. This study showed that early treatment for scrub typhus results in a good outcome in terms of early recovery and nil mortality. Regional lymphadenopathy is a marker of hidden or developing eschar. Total count and differential count should be interpreted on the background of the duration of fever. Since IgM ELISA, which is diagnostic of scrub typhus may not be widely available, any febrile child coming from rural area with hepatosplenomegaly, pallor, eschar, generalised / regional lymphadenopathy, anemia, leucocytosis, thrombocytopenia and increased Aspartate transaminase (AST) /Alanine aminotransferase (ALT) should be started on empirical Doxycycline or Azithromycin in order to prevent life threatening complications secondary to delay in

    Scrub typhus, caused by Orientia tsutsugamushi , is a common cause of acute undifferentiated febrile illness in the Asia-Pacific region. However, its nonspecific clinical manifestation often prevents early diagnosis. We propose the use of PCR and serologic tests as diagnostic tools. Here, we developed a multiplex real-time PCR assay using hydrolysis (TaqMan) probes targeting O. tsutsugamushi 47-kDa, groEL , and human interferon beta (IFN-β gene) genes to improve early diagnosis of scrub typhus. The amplification efficiency was higher than 94%, and the lower detection limit was 10 copies per reaction. We used a human gene as an internal DNA quality and quantity control. To determine the sensitivity of this PCR assay, we selected patients with confirmed scrub typhus who exhibited a clear 4-fold increase in the level of IgG and/or IgM. The PCR assay result was positive in 45 of 52 patients, indicating a sensitivity of 86.5% (95% confidence interval [CI]: 74.2 to 94.4). The PCR assessment was negative for all 136 non-scrub typhus patients, indicating a specificity of 100% (95% CI: 97.3 to 100). In addition, this test helped diagnose patients with inconclusive immunofluorescence assay (IFA) results and using single blood samples. In conclusion, the real-time PCR assay proposed here is sensitive and specific in diagnosing scrub typhus. Combining PCR and serologic tests will improve the diagnosis of scrub typhus among patients presenting with acute febrile illness. Copyright © 2017 American Society for Microbiology.

    India is an integral component of "tsutsugamushi triangle" which depicts a part of the globe endemic to scrub typhus. Owing to frequent outbreaks witnessed in different parts of the country in the recent past, scrub typhus is described as a re-emerging infectious disease in India. The present study aimed to study the clinical and paraclinical profile, complications and predictors of outcome among 90 cases of scrub typhus diagnosed in a hospital of north-eastern India from Sept 2011 to Aug 2012. A longitudinal study was conducted in a hospital of Meghalaya, India between Sept 2011 and Aug 2012. Diagnosis of scrub typhus was arrived by SD BIOLINE tsutsugamushi (solid phase immunochromatographic assay) rapid diagnostic test for antibodies (IgM, IgG or IgA). Descriptive analyses of age, gender, geographic area, symptoms and signs, treatment, laboratory findings, complications, and outcome were conducted. Relative risk (RR) with 95 % confidence interval (CI) was computed for Multiple Organ Dysfunction Syndrome (MODS) and mortality. Binary logistic regression was applied to the significant correlates (P scrub typhus. As many as 662 clinically suspected scrub typhus patients were tested and 90 (13.6 %) were diagnosed to have scrub typhus. Out of 90 patients, 52.2 % (n = 47) were males and their mean (SD) age was 36.29 (13.38) years.

    Neonatal hepatitis with acute liver failure due to varied etiology including various infections is reported in the past. Scrub typhus as a cause of neonatal hepatitis has rarely been reported in literature. A high index of clinical suspicion is required for early diagnosis and timely treatment. Severity and prognosis of the disease varies widely because several different strains of Orientia tsutsugamushi exist with different virulence. Delayed diagnosis can result in complication and significant morbidity and mortality. Here, we report three cases of neonatal hepatitis with acute liver failure caused by scrub typhus to increase awareness.

    The objective of this paper is to identify factors associated with compensation for Emergency Medical Technician (EMT)-Basics and Paramedics and assess whether these associations have changed over the period 1999-2008. Data obtained from the Longitudinal EMT Attributes and Demographic Study (LEADS) surveys, a mail survey of a random, stratified sample of nationally certified EMT-Basics and Paramedics, were analyzed. For the 1999-2003 period, analyses included all respondents providing Emergency Medical Services (EMS). With the addition of a survey in 2004 about volunteers, it was possible to exclude volunteers from these analyses. Over 60% of EMT-Basics reported being either compensated or noncompensated volunteers in the 2004-2008 period. This was substantially and significantly greater than the proportion of EMT-Paramedic volunteers (Technician (EMT)-Basics and Paramedics. Prehosp Disaster Med. 2016;31(Suppl. 1):s87-s95.

    The contemporary pharmacy practice manager faces the challenge of designing pharmacy service programs that not only satisfy the needs of the patient, but at the same time satisfy and motivate the pharmacists and technicians who sustain the programs. This research examined the team design, which has been recommended but not fully described in the literature. This application did not explore the full potential of the team design in the hospital pharmacy setting. More study is needed in this area to assess the impact of work group design on the expansion of clinical programs, employee turnover rates, quality and quantity of work produced, and, most important, the impact on job satisfaction enjoyed by pharmacists and technicians.

A survey was e-mailed to a randomized sample of 5,000 certified pharmacy technicians (CPhTs) throughout the United States, with response reminders employed. Survey items eliciting demographic and work characteristics and work life attitudes were generated from the literature and qualitative interviews. This study aimed to describe job satisfaction, sources of stress, profession and employer commitment, education and training, and reasons for entry into the profession among CPhTs and determine relationships between those variables and CPhTs' level of involvement in various work activities, with particular attention paid to differences in practice setting. Frequency statistics, correlation analysis, and means testing were used to meet study objectives and identify significant differences. A total of 516 CPhTs currently working as a pharmacy technician responded to the survey. The CPhTs reported high levels of involvement in more traditional activities but less involvement in those that involve greater cognitive load. Respondents reported moderate levels of job satisfaction and commitment and somewhat high levels of stress overall. Most CPhTs chose to be a pharmacy technician because they desired to enter a healthcare field and help people and were recruited. CPhTs derived benefit from all aspects of education and training evaluated and most from on-the-job training. Perceived value of education and training was associated with higher satisfaction and commitment and with lower stress. There were a number of differences in these work life attitudes across practice settings and by involvement in various job functions. The results of the survey indicated that job satisfaction and commitment were moderate and that stress levels were somewhat high among CPhTs. There were a number of differences in work life attitudes across practice settings and by involvement in various job

    This thesis examines the transition from the Omani Colleges of Technology (CT) to employment of its engineering graduates. It arises out of concerns that the transition to the labour market for engineering graduate is problematical. The research was carried out to identify the knowledge, skills, and abilities (KSA) of engineering technicians required in the Omani market place. The aim is to provide local curriculum designers in the Colleges of Technology with sufficient information about the required KSA in order to create and enhance the engineering curriculum so that it has greater capacity to meet the needs of a variety of stakeholders and of employers in particular. This in turn has the potential to bridge the gap between what is presently taught and what the workplace demands. Personnel psychologists identify views concerning the skills that are required for different jobs. One of these is based on the assumption that quite different skills are required in different jobs (SCANS, 1990). This view generates approaches within job analysis: the worker-oriented and the task-oriented approaches. This research uses Position Analysis Questionnaire (PAQ), which is a worker-oriented job analysis instrument, to investigate the KSA required to perform some of the engineering technician jobs in Omani industries. In addition, semi-structured interviews were used to investigate the factors that either hinder or entirely prevent the new graduates from Colleges of Technology from being accepted in the workforce pool. The major research findings concern the dimensions of knowledge, skills, and abilities of six engineering technician job titles and the major factors that hinder or (prevent) the technical college graduates from being accepted in the market place in Oman. These findings would definitely help design better transition route and bridge the gap between the CT technicians engineering programmes and the workplace demands.

    Since the working medical personnel including dentists and dental technicians mainly use their hands, it is understandable that the most common occupational disease amongst medical personnel is contact dermatitis (CD) (80%-90% of cases). Development of occupational CD is caused by contact of the skin with various substances in occupational environment. Occupational etiologic factors for dental personnel are foremost reactions to gloves containing latex, followed by various dental materials...

    Full Text Available The aim of the current investigation is to analyze the dental-technicians’ awareness of the soft relining materials, their characteristics, advantages, shortcomings and methods for relining. Materials and methods: For the purpose of this investigation a standard questionnaire has been presented. A direct survey method, documentary and statistical method, as well as graphical methods, including tables, charts, graphics and figures, were used. Data were analysed with the help of IBM SPSS Statistics (ver. 19. Results: One hundred and eight dental technicians were included in the survey, evenly distributed by gender. Removable and fixed prosthodontics is the most commonly mentioned spheres of dental activities. Almost all included in the investigation point out the laboratory relining method as the most frequently used. Acrylic and silicone SRM are the most used groups of relining materials. Change of colour and hardness are the most frequently noticed shortcomings of these materials. The majority of the dental technicians declare that they have never done replacement of SRM or the relining has lasted more than a year. Discussion: The correlation between the age and the years of labour service among the participants is quite obvious. Most of them start working soon after their graduation. Removable prosthodontics is among the priorities for the majority of the labs. Conclusion: Although their unambiguous advantages, the soft relining materials have lots of shortcomings as well. The major problems are connected with their change of colour and hardness. Nevertheless, the dental technicians find them useful and reliable in overcoming specific prosthetic problems.

    Full Text Available To clarify the geographical distribution of scrub typhus vectors in Korea, a survey of larval trombiculid mites was conducted from 2005 to 2007 by collecting wild small mammals twice a year (spring and autumn at 24 sites nationwide. A total of 67,325 mites representing 4 genera and 14 species were collected from 783 trapped rodents, corresponding to a chigger index (number of chigger mites per rodent of 86.0. The predominant mite species were Leptotrombidium pallidum (52.6%, Leptotrombiduim scutellare (27.1%, Leptotrombidium palpale (8.2%, Leptotrombidium orientale (5.6%, and Neotrombicula tamiyai (1.7%. However, the proportions of L. scutellare in southern areas, including endemic provinces such as Jeollabuk-Do (34.3%, Jeollanam-Do (49.0%, and Gyeongsangnam-Do (88%, were relatively higher than in central Korean regions where L. pallidum was predominant. In autumn, the ratio of L. scutellare increased to 42% while the ratio of L. pallidum decreased. The geographical distribution map of the L. scutellare chigger index was identical to the incidence pattern of scrub typhus, whereas those of overall mites and L. pallidum showed no relationship with case incidence patterns. Distribution mapping analysis shows an identical geographical distribution of L. scutellare and epidemic incidence of scrub typhus in South Korea. L. pallidum could be another vector at all other parts of the Korean peninsula, including the eastern and northern regions that have a low level of scrub typhus incidence.

    Scrub typhus, caused by Orientia tsutsugamushi, has recently emerged in northern China where the disease had not been known to exist. Although doxycycline and azithromycin are the recommended agents for the treatment of scrub typhus, clinical responses depend both on the susceptibilities of various O. tsutsugamushi strains and the severity of the disease. A retrospective analysis was conducted on patients diagnosed with mild scrub typhus from August 2013 to January 2016 in the Affiliated Hospital of Nantong University, northern China. A total of 40 patients who received minocycline treatment and 34 patients who received azithromycin treatment were included in the analysis. All patients except one defervesced within 120 h after initiating antimicrobial therapy. Kaplan-Meier curves in association with log-rank test showed that the median time to defervescence was significantly shorter for the minocycline-treated group than the azithromycin-treated group (P = 0.003). There were no serious adverse events during treatment. No relapse occurred in either group during the 1-month follow-up period. In conclusion, both minocycline and azithromycin are effective and safe for the treatment of mild scrub typhus, but minocycline is more active than azithromycin against O. tsutsugamushi infection acquired in northern China.

    Scrub typhus is an acute febrile illness caused by Orientia tsutsugamushi. We prospectively studied the clinico-laboratory profile and outcome of 358 children aged 1 day to 18 years diagnosed with scrub typhus from Chennai, South India. All children (100%) had fever. Eschar was seen in 67%. All children were treated with oral doxycycline and those with complications were treated with intravenous chloramphenicol/azithromycin. Rapid defervescence (within 48 h) after initiation of doxycline was seen in 306 (85%) and 52 (14.5%) developed complications. Multivariate logistic regression analysis revealed that children who had an elevated aspartate amino transferase (> 120 IU/L) and the presence of thrombocytopenia (platelet count less than 1 lac cells/mm 3 ) at admission had high risk of developing complications. The overall mortality rate in this series was 0.8%. Our 4-year study highlights the clinico-laboratory profile of Scrub typhus in children from Chennai, South India. Early recognition and prompt treatment reduces the complication and mortality. What is Known: • Scrub typhus is endemic to tsutsugamushi triangle, a geographical triangle extending from northern Japan in the east to Pakistan and Afghanistan in the west and northern Australia in the south. • There is paucity of data regarding its clinico-laboratory profile in neonates as well as its predictors of outcome. What is New: • Children who had an elevated AST and the presence of thrombocytopenia at admission had high risk of developing complications.

    The aim of this study is to investigate the clinical significance of neutrophil gelatinase-associated lipocalin (NGAL) and kidney injury molecule-1 (KIM-1) for acute kidney injury (AKI) in patients with scrub typhus. From 2014 to 2015, 145 patients were diagnosed with scrub typhus. Of these, we enrolled 138 patients who were followed up until renal recovery or for at least 3 months. We measured serum and urine NGAL and KIM-1 levels and evaluated prognostic factors affecting scrub typhus-associated AKI. Of the 138 patients, 25 had scrub typhus-associated AKI. The incidence of AKI was 18.1%; of which 11.6%, 4.3%, and 2.2% were classified as risk, injury, and failure, respectively, according to RIFLE criteria. Compared with patients in the non-AKI group, patients in the AKI group were older and showed higher total leukocyte counts and hypoalbuminemia or one or more comorbidities such as hypertension (72% vs 33%, pscrub typhus-associated AKI.

    Owing to frequent outbreaks witnessed in different parts of the country in the recent past, scrub typhus is being described as a re-emerging infectious disease in India. Differentiating scrub typhus from other endemic diseases like malaria, leptospirosis, dengue fever, typhoid, etc. is difficult due to overlapping clinical features and a lower positivity for eschars in Asian populations. Hence, the diagnosis heavily relies on laboratory tests. Costs and the need of technical expertise limit the wide use of indirect immunoperoxidase or immunofluorescence assays, ELISA and PCR. The Weil-Felix test is the most commonly used and least expensive serological test, but lacks both sensitivity and specificity. Hence, the diagnosis of scrub typhus is often delayed or overlooked. With due consideration of the cost, rapidity, single test result and simplicity of interpretation, rapid diagnostic tests have come into vogue. However, evaluation of rapid diagnostic tests for scrub typhus in the Indian population is needed to justify or discourage their use. Research studies are needed to find the most suitable test in terms of the rapidity of the result, simplicity of the procedure, ease of interpretation and cost to be used in the Indian populace.

    Full Text Available Background: Differentiating scrub typhus from other acute febrile illness is difficult due to non specificity of clinical symptoms and relative absence of eschar in Indian population. The diagnosis thus relies mainly on laboratory tests. Antibody based serological tests are mainstay of scrub typhus diagnosis. Here, we evaluated the diagnostic performance of IgM ELISA, IgM IFA and ICT to detect antibodies against O. tsutsugamushi in acute serum of febrile patients. Methodology: The serum samples from 600 randomly selected patients suffering from acute undifferentiated fever were tested by all the three tests mentioned above. We used latent class analysis to generate unbiased results as all the tests for scrub typhus diagnosis are imperfect and none of them can be considered as reference standard. Results: We found that IgM ELISA with cutoff titer 0.5 OD has high diagnostic accuracy (sensitivity 99.9% and specificity 99.15 than IgM IFA (sensitivity 96.8% and specificity 99.7% for scrub typhus diagnosis. ICT used in our study had very high specificity 100% but low sensitivity (38% which would limit its use for acute serum samples. ICT being a screening or point of care test, has to be more sensitive while some compromise with specificity is affordable. Hence, optimal cutoff for ICT should be evaluated under different settings. Conclusion: IgM ELISA being simple and affordable could be an alternative diagnostic test to IgM IFA which is subjective and costly.

    To discuss the spatial-temporal distribution and epidemic trends of autumn-winter type scrub typhus in Shandong province, and provide scientific evidence for further study for the prevention and control of the disease. The scrub typhus surveillance data during 2006-2014 were collected from Shandong Disease Reporting Information System. The data was analyzed by using software ArcGIS 9.3(ESRI Inc., Redlands, CA, USA), GeoDa 0.9.5-i and SatScan 9.1.1. The Moran' s I, log-likelihood ratio(LLR), relative risk(RR)were calculated and the incidence choropleth maps, local indicators of spatial autocorrelation cluster maps and space scaning cluster maps were drawn. A total of 4 453 scrub typhus cases were reported during 2006-2014, and the annual incidence increased with year. Among the 17 prefectures(municipality)in Shandong, 13 were affected by scrub typhus. The global Moran's I index was 0.501 5(Pscrub typhus in Shandong. Since 2006, the epidemic area of the disease has expanded and the number of high-risk areas has increased. Moreover, the eastward moving and periodically expanding trends of high-risk clusters were detected.

    The objective of this article is to assess health care worker (HCW) and patient care factors associated with bacterial contamination of scrubs. We performed a cohort study of critical care HCWs. Participants were given 4 sets of new scrubs; each set was sampled 8 times during the 8-month study period on random days in the last 4 hours of the shift. Total colony counts and presence of prespecified pathogenic bacteria were assessed. Generalized estimating equation was used to identify factors associated with contamination. There were 720 samples obtained from 90 HCWs; 30% of samples were contaminated with pathogenic bacteria. Multivariate analysis showed that providing care for patients with wounds (odds ratio [OR], 1.75; 95% confidence interval [CI], 1.17-2.62; P contamination. A second model showed the average log colony count of bacterial contamination of scrubs was higher when a bath was given (log colony count difference, 0.21; P = .05) but lower among HCWs assigned to care for at least 1 patient on contact precautions (log colony count difference, 0.28; P contaminated with bacteria. Providing care for patients with wounds or giving a bath were associated with scrub contamination by pathogenic bacteria. However, the amount of contamination was lower among HCWs who were assigned to care for patients on contact precautions.

  17. Re-caching by Western scrub-jays (Aphelocoma californica cannot be attributed to stress.

    Directory of Open Access Journals (Sweden)

    James M Thom

    Full Text Available Western scrub-jays (Aphelocoma californica live double lives, storing food for the future while raiding the stores of other birds. One tactic scrub-jays employ to protect stores is "re-caching"-relocating caches out of sight of would-be thieves. Recent computational modelling work suggests that re-caching might be mediated not by complex cognition, but by a combination of memory failure and stress. The "Stress Model" asserts that re-caching is a manifestation of a general drive to cache, rather than a desire to protect existing stores. Here, we present evidence strongly contradicting the central assumption of these models: that stress drives caching, irrespective of social context. In Experiment (i, we replicate the finding that scrub-jays preferentially relocate food they were watched hiding. In Experiment (ii we find no evidence that stress increases caching. In light of our results, we argue that the Stress Model cannot account for scrub-jay re-caching.

    Scrub typhus and malaria can involve multiple organ systems and are notoriously known for varied presentations. However, clinical malaria or scrub typhus is unusual without fever. On the other hand, altered sensorium with or without fever, dehydration, hemorrhage and hemolysis may lead to low blood pressure. Presence of toxic granules and elevated band forms in such patients can even mimic sepsis. When such a patient is in the peripartum period, it creates a strong clinical dilemma for the physician especially in unbooked obstetric cases. We present such a case where a 26-year-old unbooked female presented on second postpartum day with severe anemia, altered sensorium, difficulty in breathing along with jaundice and gum bleeding without history of fever. Rapid diagnostic test for malaria was negative and no eschar was seen. These parameters suggested a diagnosis of HELLP (Hemolysis, Elevated Liver enzymes, Low Platelet) syndrome with or without puerperal sepsis. Subsequently she was diagnosed as having asymptomatic malaria and scrub typhus and responded to the treatment of it. The biochemical changes suggestive of HELLP syndrome also subsided. We present this case to emphasize the fact that mere absence of fever and eschar does not rule out scrub typhus. It should also be considered as a differential diagnosis in patients with symptoms and signs suggesting HELLP syndrome. Asymptomatic malaria can complicate case scenario towards puerperal sepsis by giving false toxic granules and band form in such situations.

    Historically, the vital roles played by technicians in Higher Education have had little recognition. Job opportunities are often overlooked by those who have no working knowledge of such organisations and poorly defined career pathways mean that it may not be a first choice for well-qualified, ambitious individuals. With just over a third of all Higher Education technicians in the UK now due to retire in the next 10 to 15 years, fundamental changes are needed, both to attract large numbers of people into vacant roles and to retain current technical staff.National initiatives, founded and driven by charitable and professional bodies, are currently working to address the issues of technicians within Higher Education. Organisations have been urged to take action or face potential recruitment difficulties and skills gaps over the coming years. In light of these national campaigns, institutions across the UK are beginning to develop proper structured career pathways, provide professional development and improve recognition for the work of their technical workforce. Whilst these are encouraging signs, only time will tell if enough has been done to raise both the profile and appeal of a technical career in Higher Education.

    Scrub typhus is an acute febrile illness which has been reported from various parts of India with Rajasthan recently joining the list of affected states. To report a series of paediatric scrub typhus cases from rural Rajasthan. Retrospective review of children with scrub typhus admitted to the wards and paediatric intensive care unit (PICU) of a tertiary-care hospital. The study was undertaken over an 8-month period from May to December 2013. All patients with a clinical presentation and/or serological confirmation of scrub typhus who tested negative for malaria, enteric fever, dengue, leptospirosis and urinary tract infection (UTI) were included. A range of investigations were undertaken including IgM-ELISA for scrub typhus, followed by appropriate medical management. Thirty patients satisfied the inclusion criteria. The mean (SD, range) age of the patients was 8·56 (3·43, 3-16) years. The most common clinical features were fever (n = 30, 100%), headache (n = 20, 66%), myalgia (n = 15, 50%), hepatosplenomegaly (n = 18, 60%) and pallor (n = 5, 16%). Typical features such as eschar and rash were observed in only one (3·3%) and three (10%) patients, respectively; none had generalised lymphadenopathy or conjunctival congestion. IgM-ELISA for scrub typhus was positive in 28 patients (93·3%) and 27 responded to doxycycline within 24-72 hours. One of the three patients who required PICU support responded to intravenous chloramphenicol and, of the other two (6·6%), one died of acute respiratory distress syndrome and the other owing to acute renal failure. A high index of suspicion is essential for early diagnosis and prevention of complications in scrub typhus together with prompt referral from rural areas to a higher centre. Awareness of the disease manifestations may further help to prevent excessive investigations in patients presenting with non-specific febrile illness and reduce the economic burden to the family and society in resource

    Recent high-profile cases have heightened the need for a formal structure to monitor achievement and maintenance of surgical competence. Logbooks, morbidity and mortality meetings, videos and direct observation of operations using a checklist, motion analysis devices, and virtual reality simulators are effective tools for teaching and evaluating surgical skills. As the operating theater is also a place for training, there must be protocols and guidelines, including mandatory standards for supervision, to ensure that patient care is not compromised. Patients appreciate frank communication and honesty from surgeons regarding their expertise and level of competence. To ensure that surgical competence is maintained and keeps pace with technologic advances, professional registration bodies have been promoting programs for recertification. They evaluate performance in practice, professional standing, and commitment to ongoing education.

    Diagnosis of scrub typhus is challenging due to its more than twenty serotypes and the similar clinical symptoms with other acute febrile illnesses including leptospirosis, murine typhus and hemorrhagic fever with renal syndrome. Accuracy and rapidity of a diagnostic test to Orientia tsutsugamushi is an important step to diagnose this disease. To discriminate scrub typhus from other diseases, the improved ImmuneMed Scrub Typhus Rapid Diagnostic Test (RDT) was evaluated in Korea and Sri Lanka. The sensitivity at the base of each IgM and IgG indirect immunofluorescent assay (IFA) in Korean patients was 98.6% and 97.1%, and the specificity was 98.2% and 97.7% respectively. The sensitivity and specificity for retrospective diagnosis at the base of IFA in Sri Lanka was 92.1% and 96.1%. ImmuneMed RDT was not reactive to any serum from seventeen diseases including hemorrhagic fever with renal syndrome (n = 48), leptospirosis (n = 23), and murine typhus (n = 48). ImmuneMed RDT shows superior sensitivity (98.6% and 97.1%) compared with SD Bioline RDT (84.4% at IgM and 83.3% at IgG) in Korea. The retrospective diagnosis of ImmuneMed RDT exhibits 94.0% identity with enzyme-linked Immunosorbent assay (ELISA) using South India patient serum samples. These results suggest that this RDT can replace other diagnostic tests and is applicable for global diagnosis of scrub typhus. This rapid and accurate diagnosis will be beneficial for diagnosing and managing scrub typhus.

    Orientia tsutsugamushi, the causative agent of scrub typhus, is an obligate intracellular bacterium and characterized by dramatic genetic diversity. To elucidate the genotypes of O. tsutsugamushi populating in patients in Shandong Province, a new epidemic zone in China, we sequenced partial of the 56-kDa type-specific antigen gene (TSA) and identified the genotypes of 43 O. tsutsugamushi samples from human patients confirmed with scrub typhus from 2010 to 2013. All of the 43 sequences are in the same clade, 39 of them are in one branch and the other four sequences, nominated as SH1002, SH1306, SH1309, and SH1307 are in four separate branches. To clarify the clinical characterizations caused by Kawasaki-related genotypes, we studied the clinical profiles of these 43 scrub typhus patients. Most patients (88.1%) were farmers lived in rural areas. They presented with fever (100.0%), headache (79.1%), dizziness (32.6%), generalized myalgia (48.8%), fatigue (53.5%), anorexia (53.5%), facial flushing (23.3%), conjunctival congestion (11.6%), skin rashes (58.1%) and lymphadenopathy (23.3%). Eschar (97.7%) was quite common in patients, which provided doctors with a luminous clue for diagnosis of scrub typhus. Thrombocytopenia was seen in 23.1% of patients, and three patients (7.0%) had bronchopneumonia. There was no death report in Shandong Province during the study period. The present study provides beneficial data for clinical, serological, and molecular diagnosis of scrub typhus infections, and also provides foundations for subsequent studies.

    Full Text Available The aim of this study is to investigate the clinical significance of neutrophil gelatinase-associated lipocalin (NGAL and kidney injury molecule-1 (KIM-1 for acute kidney injury (AKI in patients with scrub typhus.From 2014 to 2015, 145 patients were diagnosed with scrub typhus. Of these, we enrolled 138 patients who were followed up until renal recovery or for at least 3 months. We measured serum and urine NGAL and KIM-1 levels and evaluated prognostic factors affecting scrub typhus-associated AKI.Of the 138 patients, 25 had scrub typhus-associated AKI. The incidence of AKI was 18.1%; of which 11.6%, 4.3%, and 2.2% were classified as risk, injury, and failure, respectively, according to RIFLE criteria. Compared with patients in the non-AKI group, patients in the AKI group were older and showed higher total leukocyte counts and hypoalbuminemia or one or more comorbidities such as hypertension (72% vs 33%, p<0.01, diabetes (40% vs 14%, p<0.01, or chronic kidney disease (32% vs 1%, p<0.01. In addition, serum NGAL values (404± 269 vs 116± 78 ng/mL, P<0.001, KIM-1 values (0.80± 0.52 vs 0.33± 0.68 ng/mL, P<0.001, urine NGAL/creatinine values (371± 672 vs 27± 39 ng/mg, P<0.001 and urine KIM-1/creatinine values (4.04± 2.43 vs 2.38± 1.89 ng/mg, P<0.001 were higher in the AKI group than in the non-AKI group. By multivariate logistic regression, serum NGAL and the presence of chronic kidney disease were significant predictors of AKI.Serum NGAL might be an additive predictor for scrub typhus-associated AKI.

    This paper is a report of a review to identify the non-technical (cognitive and social) skills used by scrub nurses. Recognition that failures in non-technical skills contributed to accidents in high-risk industries led to the development of research programmes to study the role of cognition and social interactions in operational safety. Recently, psychological research in operating theatres has revealed the importance of non-technical skills in safe and efficient performance. Most of the studies to date have focused on anaesthetists and surgeons. On-line sources and university library catalogues, publications of the Association for Perioperative Practice, National Association of Theatre Nurses and Association of Peri-Operative Registered Nurses were searched in 2007. Studies were included in the review if they presented data from scrub nurses on one or more of their non-technical skills. These findings were examined in relation to an existing medical non-technical skills framework with categories of communication, teamwork, leadership, situation awareness and decision-making. Of 424 publications retrieved, 13 were reviewed in detail. Ten concerned communication and eight of those also had data on teamwork. In 11 papers teamwork was examined, and one focused on nurses' situation awareness, teamwork and communication. None of the papers we reviewed examined leadership or decision-making by scrub nurses. Further work is needed to identify formally the non-technical skills which are important to the role of scrub nurse and then to design training in the identified non-technical skills during the education and development of scrub nurses.

    Scrub typhus rarely presents with acute cholecystitis. We present 2 cases of scrub typhus with cholecystitis. The first patient is a 62 year old female who presented to the hospital with fever and body aches for 1 week and right upper quadrant abdominal pain for 3 days. She gave a history of an insect bite 2 weeks previously. She was diagnosed as having acute cholecystitis and underwent cholecystectomy. She continued with fever post-operatively and physical examination revealed an eschar. She had an immunofluorescence assay (IFA) performed that revealed a high IgM titer for Orientia tsutsugamushi. She was diagnosed as having scrub typhus, treated with doxycycline and she recovered completely. The second patient also presented to the hospital with a 1 week history of fever and upper quadrant abdominal pain. She was diagnosed with having cholecystitis. Her symptoms did not improve with intravenous antibiotics and further investigation revealed elevated titers for O. tsutsugamushi and Leptospira interrogans. She was diagnosed as having a co-infection of scrub typhus and leptospirosis and treated with doxycycline. She recovered completely. Patients from scrub typhus endemic regions who present with acute cholecystitis but do not respond to traditional treatment should be tested for scrub typhus and leptospirosis and should have a careful admission physical examination looking for eschar formation, since scrub typhus may present with acute cholecystitis.

  10. Back to basics: hand hygiene and surgical hand antisepsis.

    Health care-associated infections (HAIs) are a significant issue in the United States and throughout the world, but following proper hand hygiene practices is the most effective and least expensive way to prevent HAIs. Hand hygiene is inexpensive and protects patients and health care personnel alike. The four general types of hand hygiene that should be performed in the perioperative environment are washing hands that are visibly soiled, hand hygiene using alcohol-based products, surgical hand scrubs, and surgical hand scrubs using an alcohol-based surgical hand rub product. Barriers to proper hand hygiene may include not thinking about it, forgetting, skin irritation, a lack of role models, or a lack of a safety culture. One strategy for improving hand hygiene practices is monitoring hand hygiene as part of a quality improvement project, but the most important aspect for perioperative team members is to set an example for other team members by following proper hand hygiene practices and reminding each other to perform hand hygiene.

    When the pressure in the containment building approaches a setting value, the FCVS(Filtered Containment Venting System) operates. The amount of steam and gas mixtures generated during a severe accident can be released into the FCVS. Non-condensable gases and fine aerosols can pass a scrubbing solution and the filters in the FCVS vessel. The decontaminated gases are finally discharged from the FCVS to the outside environment. Previous study observed that a scrubbing solution in the FCVS vessel was constantly evaporating owing to high-temperature steam released continuously from the containment building. A scrubbing solution in the FCVS vessel was completely evaporated at about 31 hours after the FCVS operation. Pool evaporation in the FCVS vessel can negatively affect the decontamination feature of the FCVS because it reduces the scrubbing depth for fission products in an aerosol form. This study carefully evaluated the decontamination factor of metal iodide aerosols especially cesium iodide (CsI), on a scrubbing solution in the FCVS. This paper summarizes the calculated results on the decontamination factor of CsI in the FCVS vessel, which was presented at the international OECD-NEA/NUGENIA-SARNET workshop. This study estimated the decontamination factor of CsI on a scrubbing solution in the FCVS. The MELCOR computer code simulated that an SBO occurred in the OPR 1000. The FCVS consists of a cylindrical vessel with a 3 m diameter and 6.5 m height, and it includes a scrubbing solution of 21 tons. Accumulated mass of CsI aerosol was calculated in a scrubbing solution and the atmosphere in the FCVS vessel and the outside environment. In the early FCVS operation, the decontamination factor of CsI aerosol rapidly increased owing to steam condensation in a scrubbing solution. When the temperature of a pool approached its saturation temperature, the decontamination factor of CsI aerosol started to decrease.

    2013-05-31

    This project focused on developing and deploying a comprehensive program of 22 training modules, including certification requirements, and accreditation standards for commercial building technicians, to help achieve the full savings potential of energy efficient buildings, equipment, and systems. This curriculum extended the currently available commercial building technician programs -- training a labor force in a growing market area focused on energy efficiency. The program helps to remove a major market impediment to low energy/zero energy commercial building system acceptance, namely a lack of operating personnel capable of handling more complex high efficiency systems. The project developed a training curriculum for commercial building technicians, with particular focus on high-efficiency building technology, and systems. In Phase 1, the project team worked collaboratively in developing a draft training syllabus to address project objectives. The team identified energy efficiency knowledge gaps in existing programs and plans and plans to address the gaps with either modified or new curricula. In Phase 2, appropriate training materials were developed to meet project objectives. This material was developed for alternative modes of delivery, including classroom lecture materials, e-learning elements, video segments, exercises, and hands-on training elements. A Certification and Accreditation Plan and a Commercialization and Sustainability Plan were also investigated and developed. The Project Management Plan was updated quarterly and provided direction on the management approaches used to accomplish the expected project objectives. GTI project management practices tightly coordinate project activities using management controls to deliver optimal customer value. The project management practices include clear scope definition, schedule/budget tracking, risk/issue resolution and team coordination.

    The purpose of this study was to analyze the effectiveness of an online medical laboratory technician program in the academic preparation and development of laboratory professionals. A semi-quantitative comparative research design was used. Several factors were considered in this evaluation. Academic outcomes between online and campus medical laboratory technician (MLT) students was determined by comparing overall and categorical scores on certification exams as well as first time pass rate. Certification exam scores and first time pass rates were also compared to national norms when possible to do so. Demographic data, including age and experience were compared. Additionally, learning styles were assessed to determine if there was a correlation to overall GPA and MLT GPA and if learning styles could be used to predict successful completion of an online Associates of Applied Science. The research was conducted at an academic university located in the mountain west United States. Participants consisted of online and campus students enrolled in a Medical Laboratory Technician program that graduated with their Associate of Applied Science degree between the years 2007-2009. Results of these years were also compared to graduates from 2004-2006 in the same program. Certification performance and first time pass rates were the major outcomes measured. Age and experience were correlated. Online learning styles and GPA were also compared to successful degree completion. The researcher found no significant difference in certification performance with regard to total and categorical scores, and first time pass rates between campus and online MLT students. Online students were slightly older and had more experience working in a laboratory in some capacity. Correlation studies showed significant positive correlation between learning styles, GPA, and successful completion of an Associate of Applied Science degree. When registry scores were compared to the prior cohort of online

    Emergent care of the acute heart attack patient continues to be at the forefront of quality and cost reduction strategies throughout the healthcare industry. Although the average cardiac door-to-balloon (D2B) times have decreased substantially over the past few years, there are still vast disparities found in D2B times in populations that reside in rural areas. Such disparities are mostly related to prolonged travel time and subsequent delays in cardiac catherization lab team activation. Urban ambulance companies that are routinely staffed with paramedic level providers have been successful in the implementation of pre-hospital 12-lead electrocardiogram (ECG) protocols as a strategy to reduce D2B times. The authors sought to evaluate the evidence related to the risk and benefits associated with the replication of an ECG transmission protocol in a small rural emergency medical service. The latter is staffed with emergency medical technician-basics (EMT-B), emergency medical technician-advanced (EMT-A), and emergency medical technician-intermediate (EMT-I) level. The evidence reviewed was limited to studies with relevant data regarding the challenges and complexities of the ECG transmission process, the difficulties associated with ECG transmission in rural settings, and ECG transmission outcomes by provider level. The evidence supports additional research to further evaluate the feasibility of ECG transmission at the non-paramedic level. Multiple variables must be investigated including equipment cost, utilization, and rural transmission capabilities. Clearly, pre-hospital ECG transmission and early activation of the cardiac catheterization laboratory are critical components to successfully decreasing D2B times.

    It is not fully understood where and how people are exposed to sensitizing metals. Much can be learnt from studying occupational settings where metals are handled. To quantify cobalt (Co), chromium (Cr) and nickel (Ni) exposure on the skin and in the air, and urine levels, in dental technicians working with tools and alloys that may result in skin and respiratory exposure. The metal skin dose was quantified with acid wipe sampling in dental technicians (n = 13). Air exposure was monitored by personal air sampling. Spot urine samples were collected for 24 h. Metals were analysed with inductively coupled plasma mass spectrometry. Before work, Co was detected on the skin of 10 participants (0.00025-0.0039 µg/cm 2 ), and Cr (0.00051-0.011 µg/cm 2 ) and Ni (0.0062-0.15 µg/cm 2 ) on the skin of all participants. After a 2-h period without hand washing, CoCr-exposed participants had more Co on the skin (p = 0.004) than non-CoCr-exposed participants. Co was found in 10 air samples (0.22-155 µg/m 3 ), Cr in nine (0.43-71 µg/m 3 ), and Ni in four (0.48-3.7 µg/m 3 ). Metal urine concentrations were considered to be normal. Dental technicians were exposed to Co, Cr and Ni on the skin and through the air, which was not reflected in the urine concentrations in this study. Cobalt skin doses may potentially elicit allergic contact dermatitis and cause sensitization. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

  18. Cooperative educational project for optical technicians utilizing amateur telescope making

    2004-01-01

    In the modern optical shop, technicians are typically skilled machine operators who work on only one phase of the manufacture for each and every component. The product is designed, specified, methodized, scheduled and integrated by people off the shop floor. Even at the component level, the people inside the shop usually see only one stage of completion. In an effort to make the relevance of their work visible; to demonstrate competence to their peers; to gain appreciation for the work of others; and to give them a meaningful connection with the functions of optical systems, I created "The Telescope Project" for my former employer. I invited those interested to participate in an after-hours, partially subsidized project to build telescopes for themselves. The ground-rules included that we would all make the same design (thus practicing consensus and configuration management); that we would all work on every phase (thus learning from each other); and that we would obtain our parts by random lot at the end (thus making quality assurance a personal issue). In the process the participating technicians learned about optical theory, design, tolerancing, negotiation, scheduling, purchasing, fabrication, coating and assembly. They developed an appreciation for each other's contributions and a broader perspective on the consequences of their actions. In the end, each obtained a high-quality telescope for his or her personal use. Several developed an abiding love for astronomy. The project generated much interest from technicians who didn"t initially choose to participate. In this paper I describe the project in detail.

  19. Guidelines for training and qualification of radiological protection technicians

    International Nuclear Information System (INIS)

    1987-08-01

    These guidelines, used in combination with plant-specific job analysis, provide the framework for a training and qualification program for radiological protection technicians at nuclear power plants. Radiological protection technicians are defined as those individuals, both plant and contractor, who will be engaged in the evaluation of radiological conditions in the nuclear plant and the implementation of the necessary radiological safety measures as they apply to nuclear plant workers and members of the general public. An important aspect of this work is recognizing and handling unusual situations involving radioactivity, including incidents related to degraded core conditions. These guidelines incorporate the results of an industry-wide job analysis and task analysis (JTA) combined with industry operating experience review. However, the industry-wide analyses did not identify all important academic and fundamental knowledge and skills. Further in-depth analysis by subject matter experts produced additional knowledge and skills that were added to these guidelines. All utilities should use these guidelines in conjunction with plant-specific and industry-wide JTA results to develop or validate their radiological protection technician training program. Plant-specific information should be used to establish appropriate training program content. This plant-specific information should reflect unique job duties, equipment, operating experience, and trainee entry-level qualifications. Revisions to these guidelines should be reviewed for applicability and incorporated into the training program using each utility's training system development (TSD) procedures. Plant-specific job analysis and task analysis data is essential to the development of performance-based training programs. These analyses are particularly useful in selecting tasks for training and in developing on-the-job training (OJT), laboratory training, and mock-up training. Qualification programs based on these

    The purpose of the current study was to comprehensively evaluate occupational radiation exposure to all intraoperative and perioperative personnel involved in radioguided surgical procedures utilizing 18 F-fluorodeoxyglucose ( 18 F-FDG). Radiation exposure to surgeon, anesthetist, scrub technologist, circulating nurse, preoperative nurse, and postoperative nurse, using aluminum oxide dosimeters read by optically stimulated luminescence technology, was evaluated during ten actual radioguided surgical procedures involving administration of 18 F-FDG. Mean patient dosage of 18 F-FDG was 699 ± 181 MBq (range 451-984). Mean time from 18 F-FDG injection to initial exposure of personnel to the patient was shortest for the preoperative nurse (75 ± 63 min, range 0-182) followed by the circulating nurse, anesthetist, scrub technologist, surgeon, and postoperative nurse. Mean total time of exposure of the personnel to the patient was longest for the anesthetist (250 ± 128 min, range 69-492) followed by the circulating nurse, scrub technologist, surgeon, postoperative nurse, and preoperative nurse. Largest deep dose equivalent per case was received by the surgeon (164 ± 135 μSv, range 10-580) followed by the anesthetist, scrub technologist, postoperative nurse, circulating nurse, and preoperative nurse. Largest deep dose equivalent per hour of exposure was received by the preoperative nurse (83 ± 134 μSv/h, range 0-400) followed by the surgeon, anesthetist, postoperative nurse, scrub technologist, and circulating nurse. On a per case basis, occupational radiation exposure to intraoperative and perioperative personnel involved in 18 F-FDG radioguided surgical procedures is relatively small. Development of guidelines for monitoring occupational radiation exposure in 18 F-FDG cases will provide reassurance and afford a safe work environment for such personnel. (orig.)

    We evaluated the automated system Blood Pressure Measuring System (BPMS) developed by NASA on 277 adult males who elected to have a treadmill test as part of their annual physical. The BPMS uses acoustic transduction with a computer-assisted ECG gating to detect nonsynchronous noise. The BPMS readings were compared to pressures simultaneously measured by trained technicians. For all stages of work, BPMS readings were higher for systolic and lower for diastolic than technician readings. At peak stages of work, BPMS systolic pressures were about 20 mmHg higher than technician readings. Within each 3-min workstage, BPMS readings were found to be more inconsistent than technician readings. The standard errors of measurement for BPMS were from two to three times higher than technician values. These data showed automated blood pressure readings were significantly different than technician values and subject to more random fluctuations. These findings demonstrate the need to view exercise blood pressure measured by automated systems with caution.

    Scrub typhus is a lethal infectious disease vectored by larval trombiculid mites (i.e. chiggers) infected with Orientia tsutsugamushi (OT) and recent decades have witnessed an emergence of scrub typhus in several countries. Identification of chigger species and their vertebrate hosts is fundamental for the assessment of human risks to scrub typhus under environmental changes, but intensive and extensive survey of chiggers and their hosts is still lacking in Taiwan. Chiggers were collected from shrews and rodents in nine counties of Taiwan and were assayed for OT infections with nested polymerase chain reaction (PCR). PCR products were further sequenced to reveal probable OT strains. Rodents were assessed for OT exposure by immunofluorescent antibody assay. Lastly, incidence rate of scrub typhus in each county was associated with loads and prevalence of chigger infestations, seropositivity rate in rodents, and OT positivity rate in chiggers. Rattus losea was the most abundant (48.7% of 1,285 individuals) and widespread (occurred in nine counties) small mammal species and hosted the majority of chiggers (76.4% of 128,520 chiggers). Leptotrombidium deliense was the most common (64.9% of all identified chiggers) and widespread (occurred in seven counties) chigger species but was replaced by Leptotrombidium pallidum or Leptotrombidium scutellare during the cold seasons in two counties (Matsu and Kinmen) where winter temperatures were lower than other study sites. Seropositivity rate for OT exposure in 876 assayed rodents was 43.0% and OT positivity rate in 347 pools of chiggers was 55.9%, with 15 OT strains identified in the 107 successfully sequenced samples. Incidence rate of scrub typhus was positively correlated with chigger loads, prevalence of chigger infestations, seropositivity rate but not OT positivity rate in chiggers. Our study reveals R. losea as the primary host for chiggers and there exists a geographical and seasonal variation in chigger species in

    Detection of acid-fast bacilli in respiratory specimens serves as an initial pulmonary tuberculosis (TB) diagnosis. Laboratories are the essential and fundamental part of all health systems. This study aimed to describe how laboratory technicians perceived their own self and work. This included perceived self-efficacy, perceived role, perceived equipment availability, perceived procedures, perceived reward and job, and perceived benefit of health education, as well as level of knowledge and attitudes related to work performance of laboratory technicians. This was a cross-sectional quantitative study involving 120 laboratory technicians conducted in Central Java. Interviews and observation were conducted to measure performance and work-related variables. Among 120 laboratory technicians, 43.3% showed fairly good performance. They complied with 50%-75% of all procedures, including sputum collection, laboratory tools utilization, sputum smearing, staining, smear examination, grading of results, and universal precaution practice. Perceived role, perceived self-efficacy, and knowledge of laboratory procedures were significantly correlated to performance, besides education and years of working as a laboratory technician. Perceived equipment availability was also significantly correlated to performance after the education variable was controlled. Most of the laboratory technicians believed that they have an important role in TB patients' treatment and should display proper self-efficacy in performing laboratory activities. The result may serve as a basic consideration to develop a policy for enhancing motivation of laboratory technicians in order to improve the TB control program.

    The programme was set up almost three years ago to help address a Europe-wide shortage of highly skilled technicians, with the participants gaining valuable skills and experience in an international environment. It’s clear that the programme works: some of the technician fellows who have taken part are being snapped up by major science projects and the high-tech industry.   Going underground: Fay Chicken at work in ATLAS. Fay Chicken (see UK news from CERN 59) has just accepted a job offer from the European Spallation Source in Sweden, where she will be working in the detector development team: “I’m also going to be setting up a new workshop where prototype detectors will be built. When I went to Lund, I was shown a big, empty room – it’s up to me to equip it!” This level of responsibility is a big step up for Fay, but there is no doubt that her time at CERN has both built her confidence to take on the role, and convinced ESS th...

    This report describes a project, an industry-wide Job Analysis of Nuclear Power Reactor Health Physics Technicians (HPTs), conducted by Brookhaven National Laboratory and Analysis and Technology, Inc. to provide the industry with job-performance data that can be used in systematically defining training programs in terms of required job functions responsibilities, and performance standards. The job-analysis methodology is consistent with that used by the Institute of Nuclear Power Operations (INPO) in similar industry-wide projects and includes administration of over 850 job task questionnaires to utility and contractor Health Physics Technicians throughout the country. Data collected includes task performance (difficulty, importance, and frequency) and industry-wide demographics (job levels, experience, education, and training). The results of this project discussed herein include model job descriptions for HPT positions, summaries of HPT experience, education, and training, industry-wide task listings with task-performance characteristics, and recommendations of selected tasks as a basis for HPT training development. Finally, potential future applications of the data base by utility and contractor organizations in training program development and evaluation and personnel qualifications are discussed

    Estimates show that in the U.S. approx. 75% of the health physics technicians received their training through courses offered by their employer. The quality and the extent of this training vary considerably among nuclear facilities. This paper describes a uniform approach for on-site training and qualification of health physics technicians applicable to all nuclear facilities. The program consists of four levels of qualification: Health Physics Technician Trainee, Technician I, Technician II and Senior Technician. The training is divided into modules that are composed of formal lectures, practical factors, experience, and a comprehensive examination. The minimum time required from hiring of inexperienced trainees to qualification as Senior Technicians is approx. 24 months. A qualification guide lists each step a technician must complete in the training program and provides documentation which facilitates audits by internal and external groups. Although items in the program would differ between facilities, the program provides specific titles for technicians, based on their training and experience, which would be applicable throughout the nuclear industry.

    Applied research and development activities related to the removal of tritium from aqueous effluent streams have presented broad opportunities to the chemical engineering technician for professional growth. Technician job activities involve operating complex analytical instrumentation and constructing, maintaining, and operating experimental electrolysis apparatus. The technician is a member of a professional team including scientific, engineering, and other technical personnel and as such is expected to exercise creative thought. Proximity of a large university and availability of formalized ''in house'' training courses provide incentives for technicians to broaden their academic base concurrent with their work involvement

    Full Text Available Scrub typhus is an acute febrile illness that is known to be endemic in the South East Asian countries and the Western Pacific region. We here report an outbreak in the tiny Himalayan state of Sikkim. Patients with pyrexia of unknown origin were evaluated. They were screened by Weil-Felix test and the rapid immunochromatographic method. Samples that were positive by either Weil-Felix agglutination test or by rapid immunochromatography were confirmed by IgM enzyme-linked immunosorbent assay (ELISA. A total 204 samples were screened. Sixty-three patients were confirmed positive among which 42 were male and 21 were female. Effective management and early administration of antibiotics will help prevent the complications and mortality associated with scrub typhus.

    When a patient presents with acute voiding dysfunction without a typical skin rash, it may be difficult to make a diagnosis of herpes zoster. Here, we present a case of scrub typhus in a 25-year-old man with the complication of urinary dysfunction. The patient complained of loss of urinary voiding sensation and constipation. After eight days, he had typical herpes zoster eruptions on the sacral dermatomes and hypalgesia of the S1-S5 dermatomes. No cases of dual infection with varicella zoster virus and Orientia tsutsugamushi were found in the literature. In the described case, scrub typhus probably induced sufficient stress to reactivate the varicella zoster virus. Early recognition of this problem is imperative for prompt and appropriate management, as misdiagnosis can lead to long-term urinary dysfunction. It is important that a diagnosis of herpes zoster be considered, especially in patients with sudden onset urinary retention.

    Natural killer (NK) cells are essential immune cells against several pathogens. Not much is known regarding the roll of NK cells in Orientia tsutsugamushi infection. Thus, this study aims to determine the level, function, and clinical relevance of NK cells in patients with scrub typhus. This study enrolled fifty-six scrub typhus patients and 56 health controls (HCs). The patients were divided into subgroups according to their disease severity. A flow cytometry measured NK cell level and function in peripheral blood. Circulating NK cell levels and CD69 expressions were significantly increased in scrub typhus patients. Increased NK cell levels reflected disease severity. In scrub typhus patients, tests showed their NK cells produced higher amounts of interferon (IFN)-γ after stimulation with interleukin (IL)-12 and IL-18 relative to those of HCs. Meanwhile, between scrub typhus patients and HCs, the cytotoxicity and degranulation of NK cells against K562 were comparable. CD69 expressions were recovered to the normal levels in the remission phase. This study shows that circulating NK cells are activated and numerically increased, and they produced more IFN-γ in scrub typhus patients.

    Scrub typhus usually presents as acute undifferentiated fever. This cross-sectional study included adult patients presenting with acute undifferentiated fever defined as any febrile illness for ≤ 14 days without evidence of localized infection. Scrub typhus cases were defined by an antibody titer of a ≥ fourfold increase in paired sera, a ≥ 1:160 in a single serum using indirect immunofluorescence assay, or a positive result of the immunochromatographic test. Multiple regression analysis identified predictors associated with scrub typhus to develop a prediction rule. Of 250 cases with known etiology of acute undifferentiated fever, influenza (28.0%), hepatitis A (25.2%), and scrub typhus (16.4%) were major causes. A prediction rule for identifying suspected cases of scrub typhus consisted of age ≥ 65 years (two points), recent fieldwork/outdoor activities (one point), onset of illness during an outbreak period (two points), myalgia (one point), and eschar (two points). The c statistic was 0.977 (95% confidence interval = 0.960–0.994). At a cutoff value ≥ 4, the sensitivity and specificity were 92.7% (79.0–98.1%) and 90.9% (86.0–94.3%), respectively. Scrub typhus, the third leading cause of acute undifferentiated fever in our region, can be identified early using the prediction rule. PMID:25448236

    Full Text Available Scrub typhus is a neglected tropical disease, caused by Orientia tsutsugamushi, a Gram-negative bacterium that is transmitted to mammalian hosts during feeding by Leptotrombidium mites and replicates predominantly within endothelial cells. Most studies of scrub typhus in animal models have utilized either intraperitoneal or intravenous inoculation; however, there is limited information on infection by the natural route in murine model skin or its related early host responses. Here, we developed an intradermal (i.d. inoculation model of scrub typhus and focused on the kinetics of the host responses in the blood and major infected organs. Following ear inoculation with 6 x 104 O. tsutsugamushi, mice developed fever at 11-12 days post-infection (dpi, followed by marked hypothermia and body weight loss at 14-19 dpi. Bacteria in blood and tissues and histopathological changes were detected around 9 dpi and peaked around 14 dpi. Serum cytokine analyses revealed a mixed Th1/Th2 response, with marked elevations of MCP-1/CCL2, MIP-1α/CCL3 and IL-10 at 9 dpi, followed by increased concentrations of pro-inflammatory markers (IL-6, IL-12, IFN-γ, G-CSF, RANTES/CCL5, KC/CCL11, IL-1α/β, IL-2, TNF-α, GM-CSF, as well as modulatory cytokines (IL-9, IL-13. Cytokine levels in lungs had similar elevation patterns, except for a marked reduction of IL-9. The Orientia 47-kDa gene and infectious bacteria were detected in several organs for up to 84 dpi, indicating persistent infection. This is the first comprehensive report of acute scrub typhus and persistent infection in i.d.-inoculated C57BL/6 mice. This is a significant improvement over current murine models for Orientia infection and will permit detailed studies of host immune responses and infection control interventions.

    Full Text Available Background: The most common method employed for diagnosis of scrub typhus is serology. It is widely known that demonstration of ≥4-fold rise in titers of antibody in paired sera is required for diagnosis. However, for guidance of initial treatment, there is a need for rapid diagnosis at the time of admission. Therefore, there is a need for standardized region specific cutoff titers at the time of admission. Materials and Methods: A total of 258 patients of all age groups with clinically suspected scrub typhus over a period of 24 months (October 2013-October 2015 were enrolled. Serum samples of these patients were subjected to immunofluorescent antibody (IFA for immunoglobulin M (IgM (Fuller Labs, USA with dilutions of 1:64, 1:128, 1:256, and 1:512. Serum samples of all 258 patients were subjected to IgM ELISA (Inbios Inc., USA. Any patient with response to antibiotics within 48 h accompanied by either presence of an eschar or positivity by polymerase chain reaction was taken as positive. Receiver operating characteristic (ROC curve was drawn to generate cutoff for these tests. Results: A total of 20 patients were diagnosed as cases of scrub typhus. The ROC curve analysis revealed a cutoff optical density value of 0.87 with sensitivity and specificity of 100% and 94.12%, respectively. ROC curve analysis of IFA revealed sensitivity and specificity of 100% and 93.5%, respectively at 1:64 dilution. Conclusion: Considering cost constraints, centers in and around New Delhi region can use the cutoffs we determined for the diagnosis of scrub typhus.

  20. Characterisation of plastic microbeads in facial scrubs and their estimated emissions in Mainland China.

    Plastic microbeads are often added to personal care and cosmetic products (PCCPs) as an abrasive agent in exfoliants. These beads have been reported to contaminate the aquatic environment and are sufficiently small to be readily ingested by aquatic organisms. Plastic microbeads can be directly released into the aquatic environment with domestic sewage if no sewage treatment is provided, and they can also escape from wastewater treatment plants (WWTPs) because of incomplete removal. However, the emissions of microbeads from these two sources have never been estimated for China, and no regulation has been imposed on the use of plastic microbeads in PCCPs. Therefore, in this study, we aimed to estimate the annual microbead emissions in Mainland China from both direct emissions and WWTP emissions. Nine facial scrubs were purchased, and the microbeads in the scrubs were extracted and enumerated. The microbead density in those products ranged from 5219 to 50,391 particles/g, with an average of 20,860 particles/g. Direct emissions arising from the use of facial scrubs were estimated using this average density number, population data, facial scrub usage rate, sewage treatment rate, and a few conservative assumptions. WWTP emissions were calculated by multiplying the annual treated sewage volume and estimated microbead density in treated sewage. We estimated that, on average, 209.7 trillion microbeads (306.9 tonnes) are emitted into the aquatic environment in Mainland China every year. More than 80% of the emissions originate from incomplete removal in WWTPs, and the remaining 20% are derived from direct emissions. Although the weight of the emitted microbeads only accounts for approximately 0.03% of the plastic waste input into the ocean from China, the number of microbeads emitted far exceeds the previous estimate of plastic debris (>330 μm) on the world's sea surface. Immediate actions are required to prevent plastic microbeads from entering the aquatic environment

    Scrub typhus, a bacterial zoonosis caused by Orientia tsutsugamushi, may cause multiorgan dysfunction syndrome (MODS) and is associated with significant mortality. This study was undertaken to document the clinical and laboratory manifestations and complications and to study time trends and factors associated with mortality in patients with scrub typhus infection. This retrospective study, done at a university teaching hospital, included 623 patients admitted between 2005 and 2010 with scrub typhus. The diagnosis was established by a positive IgM ELISA and/or pathognomonic eschar with PCR confirmation where feasible. The clinical and laboratory profile, course in hospital, and outcome were documented. Factors associated with mortality were analyzed using multivariate logistic regression analysis. The most common presenting symptoms were fever (100%), nausea/vomiting (54%), shortness of breath (49%), headache (46%), cough (38%), and altered sensorium (26%). An eschar was present in 43.5% of patients. Common laboratory findings included elevated transaminases (87%), thrombocytopenia (79%), and leukocytosis (46%). MODS was seen in 34% of patients. The overall case-fatality rate was 9.0%. Features of acute lung injury were observed in 33.7%, and 29.5% required ventilatory support. On multivariate analysis, shock requiring vasoactive agents (relative risk (RR) 10.5, 95% confidence interval (CI) 4.2-25.7, p<0.001), central nervous system (CNS) dysfunction (RR 5.1, 95% CI 2.4-10.7, p<0.001), and renal failure (RR 3.6, 95% CI 1.7-7.5, p=0.001) were independent predictors of mortality. Over 4 years, a decreasing trend was observed in the mortality rate. Scrub typhus can manifest with potentially life-threatening complications such as lung injury, shock, and meningoencephalitis. MODS occurred in a third of our patients. The overall case-fatality rate was 9%, with shock, renal failure, and CNS associated with a higher mortality. Copyright © 2014 The Authors. Published by

    Full Text Available OBJECTIVES The purpose of this study was to establish a basis for improving or strengthening the preventive strategy against scrub typhus in Korea by comparing and analyzing the difference of prevention behaviors contributing to the occurrence of scrub typhus in Japan and Korea. METHODS The survey was carried out in Jeollabuk-do, which is a high risk and high incidence area, and Fukuoka Prefecture, which is a high risk and low incidence area. The study included 406 Korean farmers and 216 Japanese farmers. Data were collected through face-to-face surveys by interviewers who had completed standardized education. RESULTS Korean farmers have a higher percentage of agricultural working posture that involved contact with weeds than Japanese farmers (p<0.05. The frequency and proportion of weeding were lower in Korean farmers than in Japanese farmers (p<0.05. The level of knowledge about scrub typhus was significantly higher among Korean farmers than among Japanese farmers (p<0.05. Mostly, the behavior of agriculture work was more appropriate for Japanese farmers than for Korean farmers (p<0.05. The total average level of agricultural work was lower in Korea than in Japan, lower in men than women, and lower in part-time farmers than full-time farmers (p<0.05. CONCLUSIONS This study suggests that it is reasonable to develop and provide a program that can improve the level of preventive behavior taking into consideration the characteristics of the subject in order to reduce the incidence of diseases in high-risk areas for scrub typhus.

    Scrub typhus can produce multiple organ dysfunction syndrome (MODS). Early recognition of the patients at risk of MODS would be helpful in providing timely management and reducing the mortality. In all, 449 children with scrub typhus were enrolled at three hospitals in Yunnan, China from January 2010 to January 2015. The patients' clinical status of organ system dysfunction was evaluated on the day of discharge from hospital by using standard criteria. The patients were classified into MODS present (64 cases, 14.3%) or MODS absent (385 cases, 85.7%). Multivariate logistic regression analyses revealed that the prognostic factors for MODS included skin rash (odds ratio, OR = 3.3, p = 0.037), time interval form treatment to defervescence (OR = 1.2, p = 0.035), hemoglobin (OR = 0.54, p = 0.041), platelet counts (OR = 0.06, p scrub typhus, our study provides clinicians with important information to improve the clinical monitoring and prognostication of MODS. © The Author [2016].

    Scrub typhus is endemic in Thailand. Of the 495 patients with acute undifferentiated fever studied in Maharat Nakhon Ratchasima Hospital, Nakhon Ratchasima, Thailand, from June 1, 2011, to December 31, 2012, 146 patients (29.5%) had confirmed scrub typhus. The majority of cases were male, farmers, with the mean (±standard deviation) age of 54.1 ± 15.2 years. A total of 59 patients (40.4%) had eschar lesion. The commonest sites for an eschar in male patients were the perineum, inguinal, and buttock area; whereas in females, it was the head and neck area. Abnormal electrocardiogram was found in 39 of 79 patients (49.4%) with sinus tachycardia being the most frequent finding (17, 21.5%). A total of 73 patients (50%) had at least one complication. Myocarditis was the cause of complete heart block in a scrub typhus patient, and he fully recovered after receiving intravenous chloramphenicol treatment. The case fatality rate was 6.2% (nine deaths).The independent predictors for fatal outcome were age over 65 years (odds ratio [OR] = 14.49, 95% confidence interval [CI] = 1.26-166.44, P = 0.03), acute kidney injury (OR = 12.75, 95% CI = 1.77-92.07, P = 0.01), and hyperbilirubinemia (OR = 24.82, 95% CI = 2.12-286.61, P = 0.01).

    Neurological involvement in the form of meningitis or meningoencephalitis, although well documented in scrub typhus, has not been extensively studied in the pediatric population. We report the clinical and laboratory profile of 96 children with scrub typhus and compared those with and without meningitis. Twenty seven (28%) children had clinical and laboratory evidence of meningitis. The most frequent presenting features were fever (100%), meningeal signs (66.6%), nausea and vomiting (56.3%), seizures (55.5%) and altered sensorium (51.8%). The children with meningitis presented early and had significantly lower respiratory and renal impairments when compared with the non-meningitis group. Cerebrospinal fluid (CSF) analysis revealed elevated total leukocyte count (86.73 ± 94.50 cells/mm(3)), mononuclear pleocytosis (lymphocyte percentage of 76.85 ± 15.86), elevated proteins (108.33 ± 52.63 mg%) and normal CSF glucose (64.18 ± 15.92 mg%). We conclude that meningitis is a common and early complication of childhood scrub typhus. The CSF reveals a lymphocytic pleocytosis, raised proteins and a normal glucose level. These children respond promptly to appropriate antibiotics as do children without meningitis. © The Author [2016]. Published by Oxford University Press. All rights reserved.

    Treated guava scrub granules (GSG) as an exfoliating agent were obtained from the decanter waste at Sime Darby Food and Beverages, Sungai Wangi, Perak (SDFB). The treated GSG and tocotrienol were the main active ingredients incorporated in a basic formulation containing 87 % palm-based derivatives. Guava body scrub (GBS) and guava facial scrub (GFS) lotions were developed at skin pH 5.5 and pH 5.6 respectively. Both products were found to be stable for three years due to the liquid crystalline structure in the emulsion system , having small particle size (490 nm and 880 nm) and high zeta potential values (-54 mv and -39 mv). The rheological properties showed that the GBS lotion had a viscosity at 900 Pas and a yield value at 98 Pa, whereas the GFS lotion 60 Pas and 6 Pa viscosity and yield values respectively. The formulations were designed to be soft and flowable, with the firmness force indicated at 111 g and 66 g for GBS lotion and GFS lotion respectively. Efficacy testing on 20 healthy subjects showed a significant decrease of 21 % and 22 % in skin sebum removal for GBS lotion and GFS lotion respectively. (author)

  9. Influence of attrition scrubbing, ultrasonic treatment, and oxidant additions on uranium removal from contaminated soils

    1994-01-01

    As part of the Uranium in Soils Integrated Demonstration Project being conducted by the US Department of Energy, bench-scale investigations of selective leaching of uranium from soils at the Fernald Environmental Management Project site in Ohio were conducted at Oak Ridge National Laboratory. Two soils (storage pad soil and incinerator soil), representing the major contaminant sources at the site, were extracted using carbonate- and citric acid-based lixiviants. Physical and chemical processes were used in combination with the two extractants to increase the rate of uranium release from these soils. Attrition scrubbing and ultrasonic dispersion were the two physical processes utilized. Potassium permanganate was used as an oxidizing agent to transform tetravalent uranium to the hexavalent state. Hexavalent uranium is easily complexed in solution by the carbonate radical. Attrition scrubbing increased the rate of uranium release from both soils when compared with rotary shaking. At equivalent extraction times and solids loadings, however, attrition scrubbing proved effective only on the incinerator soil. Ultrasonic treatments on the incinerator soil removed 71% of the uranium contamination in a single extraction. Multiple extractions of the same sample removed up to 90% of the uranium. Additions of potassium permanganate to the carbonate extractant resulted in significant changes in the extractability of uranium from the incinerator soil but had no effect on the storage pad soil

    Full Text Available Scrub typhus and the rickettsial diseases represent some of the oldest recognized vector-transmitted diseases, fraught with a rich historical aspect, particularly as applied to military/wartime situations. The vectors of Orientia tsutsugamushi were once thought to be confined to an area designated as the Tsutsugamushi Triangle. However, recent reports of scrub typhus caused by Orientia species other than O. tsutsugamushi well beyond the limits of the Tsutsugamushi Triangle have triggered concerns about the worldwide presence of scrub typhus. It is not known whether the vectors of O. tsutsugamushi will be the same for the new Orientia species, and this should be a consideration during outbreak/surveillance investigations. Additionally, concerns surrounding the antibiotic resistance of O. tsutsugamushi have led to considerations for the amendment of treatment protocols, and the need for enhanced public health awareness in both the civilian and medical professional communities. In this review, we discuss the history, outbreaks, antibiotic resistance, and burgeoning genomic advances associated with one of the world’s oldest recognized vector-borne pathogens, O. tsutsugamushi.

    Scrub typhus is endemic in the Asia-Pacific region. Mortality is high even with treatment, and further knowledge of the immune response during this infection is needed. This study was aimed at comparing plasma levels of monocyte/macrophage and endothelial related inflammatory markers in patients and controls in South India and to explore a possible correlation to disease severity and clinical outcome. Plasma levels of ALCAM, VCAM-1, sCD163, sCD14, YKL-40 and MIF were measured in scrub typhus patients (n = 129), healthy controls (n = 31) and in infectious disease controls (n = 31), both in the acute phase and after recovery, by enzyme immunoassays. Patients had markedly elevated levels of all mediators in the acute phase, differing from both healthy and infectious disease controls. During follow-up levels of ALCAM, VCAM-1, sCD14 and YKL-40 remained elevated compared to levels in healthy controls. High plasma ALCAM, VCAM-1, sCD163, sCD14, and MIF, and in particular YKL-40 were all associated with disease severity and ALCAM, sCD163, MIF and especially YKL-40, were associated with mortality. Our findings show that scrub typhus is characterized by elevated levels of monocyte/macrophage and endothelial related markers. These inflammatory markers, and in particular YKL-40, may contribute to disease severity and clinical outcome. Copyright © 2014 The British Infection Association. Published by Elsevier Ltd.

    Scrub typhus (Tsutsugamushi disease) is an acute febrile systemic illness caused by Rickettsia Tsutsugamushi that is transmitted to humans by the bite of larval-stage trombiculid mites (chiggers). The authors analyzed chest radiographic findings of scrub typhus in 160 patients in Ulsan area. One hundred and eight (67.5%) of 160 patients showed abnormal findings which included lung lesions in 108 patients (67.5%), cardiomegaly in 37 patients (23.1%), lymphadenopathy in 25 patients (15.6%) and pleural effusion in 11 patients (6.9%). Among the lung lesions, interstitial patterns were seen in 107 patients (66.9%), mostly fine or medium reticulonodular, and air-space patterns in 14 patients (8.8%) and combined interstitial and air-space patterns in 13 patients (8.1%). Sixty-four patients (40%) had combined chest radiographic findings. The typical chest radiographic findings of scrub typhus would be helpful in evaluation of the causes of acute febrile illness that occur during late fall in the endemic area.

    The purpose of this study was to establish a basis for improving or strengthening the preventive strategy against scrub typhus in Korea by comparing and analyzing the difference of prevention behaviors contributing to the occurrence of scrub typhus in Japan and Korea. The survey was carried out in Jeollabuk-do, which is a high risk and high incidence area, and Fukuoka Prefecture, which is a high risk and low incidence area. The study included 406 Korean farmers and 216 Japanese farmers. Data were collected through face-to-face surveys by interviewers who had completed standardized education. Korean farmers have a higher percentage of agricultural working posture that involved contact with weeds than Japanese farmers (pwork was more appropriate for Japanese farmers than for Korean farmers (pwork was lower in Korea than in Japan, lower in men than women, and lower in part-time farmers than full-time farmers (p<0.05). This study suggests that it is reasonable to develop and provide a program that can improve the level of preventive behavior taking into consideration the characteristics of the subject in order to reduce the incidence of diseases in high-risk areas for scrub typhus.

    Emissions reduction in industrial processes, i.e. clean production, is an essential requirement for sustainable development. Fossil fuel combustion is the main emission source for gas pollutants, such as NO X , SO 2 and CO 2 , and coal is now a primary energy source used worldwide with coal combustion being the greatest atmospheric pollution source in China. This paper analyzes flue gas cleaning by ammonia scrubbing (FGCAS) for power plants to remove gaseous pollutants, such as NO X , SO 2 and CO 2 , and presents the conceptual zero emission design for power plants. The byproducts from the FGCAS process can be used in agriculture or for gas recovery. Experimental results presented for SO 2 removal from the simulated flue gas in a continuous flow experiment, which was similar to an actual flue gas system, showed that the effectiveness of the ammonia injection or scrubbing depends on the temperature. The FGCAS process can effectively remove SO 2 , but the process temperature should be below 60 deg. C or above 80 deg. C for SO 2 reduction by NH 3 scrubbing

    The clinical experience and preferred learning style of U.S. Air Force flight nurses and aeromedical evacuation technicians are unknown. Using a cross-sectional survey design, we gathered data regarding the clinical experience, level of comfort providing clinical care, and preferred learning style of 77 active duty (AD), Air Force Reserve (AFR), and Air National Guard (ANG) nurses enrolled in the U.S. Air Force School of Aerospace Medicine Flight Nurse course, and 121 AD, AFR, and ANG medical technicians enrolled in the Aeromedical Evacuation Technician course. Nurses and medical technicians reported 7.6 ± 5.5 and 3.9 ± 4.5 yr of experience, respectively. AD, AFR, and ANG nurses had comparable years of experience: 5.8 ± 3.2, 8.3 ± 6.6, and 7.9 ± 4.2 yr, respectively; however, AD medical technicians had more years of experience (5.6 ± 4.4 yr) than AFR (3.1 ± 4.8 yr) and ANG (1.9 ± 2.8 yr) medical technicians. Both nurses and medical technicians reported infrequently caring for patients with various disease processes and managing equipment or devices that they will routinely encounter when transporting patients as an aeromedical evacuation clinician. Nurses and medical technicians preferred a kinesthetic learning style or a multimodal learning style that included kinesthetic learning. Nearly all (99%) nurses and 97% of medical technicians identified simulation as their preferred teaching method. These findings confirm faculty concerns regarding the clinical experience of flight nurse and aerospace evacuation technician students.De Jong MJ, Dukes SF, Dufour KM, Mortimer DL.

    To describe the creation of a clinical pharmacy technician position within the U.S. Army and to identify the personal skills and characteristics required to meet the demands of this role. An outpatient military treatment facility located in Maryland. The clinical pharmacy technician position was designed to support clinical pharmacy services within a patient-centered medical home. Funding and a position description were established to hire a clinical pharmacy technician. Expected duties included administrative (45%), patient education (30%), and dispensing (25%). Local policy, in accordance with federal law and U.S. Army regulations, was developed to define the expanded technician responsibility to deliver patient medication education. In the initial 3 months, the clinical pharmacy technician spent 24 hours per week on clinical activities, affording an additional 10-15 hours per week for clinical pharmacists to provide patient care. Completed consults increased from 41% to 56%, and patient-pharmacist encounters increased from 240 to 290 per month. The technician, acting as a clinical pharmacist extender, also completed an average of 90 patient encounters independently each month. As a result of these improvements, the decision was made to hire a second technician. Currently, the technicians spend 28-40 hours per week on clinical activities, offsetting an average of 26 hours per week for the clinical pharmacists. A patient-centered medical home clinical pharmacy technician can reduce the administrative workload for clinical pharmacists, improve their efficiency, and enhance the use of clinical pharmacy services. Several characteristics, particularly medication knowledge, make pharmacy technicians particularly suited for this role. The results from the implementation of a clinical pharmacy technician at this military treatment facility resulted in an Army-wide expansion of the position and suggested applicability in other practice sites, particularly in federal

    OBJECTIVE : The purpose of this study was to elicit feedback from simulation technicians prior to developing the first simulation technician-specific simulation laboratory in Akron, OH. Simulation technicians serve a vital role in simulation centers within hospitals/health centers around the world. The first simulation technician degree program in the US has been approved in Akron, OH. To satisfy the requirements of this program and to meet the needs of this special audience of learners, a customized simulation lab is essential. A web-based survey was circulated to simulation technicians prior to completion of the lab for the new program. The survey consisted of questions aimed at identifying structural and functional design elements of a novel simulation center for the training of simulation technicians. Quantitative methods were utilized to analyze data. Over 90% of technicians (n=65) think that a lab designed explicitly for the training of technicians is novel and beneficial. Approximately 75% of respondents think that the space provided appropriate audiovisual (AV) infrastructure and space to evaluate the ability of technicians to be independent. The respondents think that the lab needed more storage space, visualization space for a large number of students, and more space in the technical/repair area. CONCLUSIONS : A space designed for the training of simulation technicians was considered to be beneficial. This laboratory requires distinct space for technical repair, adequate bench space for the maintenance and repair of simulators, an appropriate AV infrastructure, and space to evaluate the ability of technicians to be independent.

    Renal involvement and acute kidney injury (AKI) are common clinical manifestations seen in scrub typhus, a vector-borne tropical disease. There are no data on renal manifestation in scrub typhus in Nepal. We conducted a prospective study to analyze the incidence, urinary abnormalities, course, severity, outcome, and the predictors of AKI in patients with scrub typhus during a major outbreak in Central Nepal. Total 1398 patients admitted with acute febrile illness were subjected for Scrub Typhus Detect™ Immunoglobulin M (IgM) enzyme-linked immunosorbent assay (ELISA) test, of which 502 (35.90%) patients tested positive and were included in the study. Mean age of the patients was 30.37 ± 18.81 years (range, 1-79 years) with 26.29% in the pediatric age group. Female-to-male ratio was 1.26:1. Mean duration of fever was 6.8 ± 3.1 days. Mean IgM ELISA value for scrub typhus was 2.17 ± 1.70 without difference in AKI and non-AKI groups (2.17 ± 1.76 vs. 2.16 ± 1.62; P = 0.94). Urinary abnormalities were seen in 42.3% of patients. Mean serum creatinine was 1.37 ± 0.69 mg/dl with significant difference in two groups (1.85 ± 0.87 vs. 1.03 ± 0.17; P = 0.003). AKI was seen in 35.8% of patients with majority having Stage 1 AKI (68.3%) followed by Stage 2 (34.1%) and Stage 3 (1.2%). Hemodialysis was required for 3.94% of patients. In 54% of patients, AKI occurred in fifth and sixth day of fever. ICU admission was required for 18.73% of patients and 8.57% required ventilator support. Mortality rate was 1.79%, which was higher among patients with AKI (2.96% vs. 1.0%; P = 0.106). Multivariate analysis revealed that the presence of pneumonia, shock, and acute respiratory distress syndrome predicted the development of AKI.

    Full Text Available Diagnosing scrub typhus clinically is difficult, hence laboratory tests play a very important role in diagnosis. As performing sophisticated laboratory tests in resource-limited settings is not feasible, accurate point-of-care testing (POCT for scrub typhus diagnosis would be invaluable for patient diagnosis and management. Here we summarise the existing evidence on the accuracy of scrub typhus POCTs to inform clinical practitioners in resource-limited settings of their diagnostic value.Studies on POCTs which can be feasibly deployed in primary health care or outpatient settings were included. Thirty-one studies were identified through PubMed and manual searches of reference lists. The quality of the studies was assessed with the Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS-2. About half (n = 14/31 of the included studies were of moderate quality. Meta-analysis showed the pooled sensitivity and specificity of commercially available immunochromatographic tests (ICTs were 66.0% (95% CI 0.37-0.86 and 92.0% (95% CI 0.83-0.97, respectively. There was a significant and high degree of heterogeneity between the studies (I2 value = 97.48%, 95% CI 96.71-98.24 for sensitivity and I2 value = 98.17%, 95% CI 97.67-98.67 for specificity.

Overall, the commercially available scrub typhus ICTs demonstrated better performance when 'ruling in' the diagnosis. There is a need for standardised methods and reporting of diagnostic accuracy to decrease between-study heterogeneity and increase comparability among study results, as well as development of an affordable and accurate antigen-based POCT to tackle the

Methods:This work presents a quantitative, cross-sectional descriptive study held with students of seven classes in dental hygiene course conducted by the School of Public Health. Data collection was conducted between March and April 2011, through the application of a semistructured questionnaire, which addressed the professional profile of the participants, their expectations about the labor market and the profession. Statistical analysis was performedwith a degree of significance of 0.05. Results: 154 students were interviewed, of whom 96.1% were women, mean age of 32.9 (± 7.3 years. Most (93.8%, N = 120 graduated from high school and 71.1% (N = 108 were registered at the Regional Council of Dentistry. Regardingtheir insertion in the labor market, 42.9% believed it would be satisfactory and 58% that it would occur in public service. The biggest obstacle mentioned by the subjects about the insertion of oral health technicians in the labor market was the difficulty of hiring (45.5%. When asked to punctuate some actions that they would play as TSB, 82.2% cited clinical and collective actions. The majority (96% claimed to feel safe to act as TSB. Conclusion:The students’ expectations regarding their professional future are positive. However, it is necessary to develop further research in this area, so that the profession has a growing support within the labor market.

    Core competencies are considered the foundation for establishing Emergency Medical Technician (EMT) and paramedic curricula, and for ensuring performance standards in the delivery of prehospital care. This study surveyed EMT instructors and medical directors to identify the most desirable core competencies for all levels of EMTs in Taiwan. A principal components analysis with Varimax rotation was conducted. An online questionnaire was distributed to obtain perspectives of EMT instructors and medical directors on the most desirable core competencies for EMTs. The target population was EMT training-course instructors and medical directors of fire departments in Taiwan. The questionnaire comprised 61 competency items, and multiple-choice and open-ended questions were used to obtain respondents' perspectives of the Taiwanese EMT training and education system. The results identified three factors at EMT-1 and EMT-2 levels and five factors at the EMT-Paramedic level. The factors for EMT-1 and EMT-2 were similar, and those for EMT-Paramedics identified further comprehensive competence perspectives. The key factors that appear to influence the development of the Taiwanese Emergency Medical Services (EMS) education system are the attitude of authorities, the licensure system, and legislation. The findings present new core competencies for the Taiwanese EMT system and provide capacity to redesign curricula and reconsider roles for EMT-1 and EMT-2 technicians. At the EMT-Paramedic level, the findings demonstrate the importance of incorporating competency standards in the current skills-based curriculum. Moreover, the core-competencies gap that exists between Taiwanese EMT-1s, EMT-2s, and EMT-Paramedics and internationally recognized core competencies needs to be addressed. By identifying the key factors that potentially impact the development of the EMS education system, such as the attitude of authorities, the licensure system, and legislation, these findings will inform

    Full Text Available This study prepared a basic framework for the development and improvement of Korean Dental Technicians' Licensing Examination, based on actual test questions. A peer review was conducted to ensure relevance to current practices in dental technology. For the statistical analysis, 1000 dental laboratory technicians were selected; specialists in dental laboratory technology (laboratory owners, educators, etc. were involved in creating valid and reliable questions. Results indicated that examination subjects should be divided into three categories: basic dental laboratory theory, dental laboratory specialties, and a practical examination. To ensure relevance to current practice, there should be less emphasis on basic dental laboratory theory, including health-related laws, and more emphasis on dental laboratory specialties. Introduction to dental anatomy should be separated from oral anatomy and tooth morphology; and fixed prosthodontics should be separated from crown and bridge technology and dental ceramics technology. Removable orthodontic appliance technology should be renamed 'orthodontic laboratory technology'. There should be less questions related to health related law, oral anatomy, dental hygiene, dental materials science and inlay, while the distribution ratio of questions related to tooth morphology should be maintained. There should be a decrease in the distribution ratio of questions related to crown and bridge technology, dental ceramics technology, complete dentures and removable partial dentures technology, and orthodontic laboratory technology. In the practical examination, the current multiple choice test should be replaced with tooth carving using wax or plaster. In dental laboratory specialties, subjects related to contemporary dental laboratory technology should be included in the test items.

    Scrub typhus is lesser known cause of fever of unknown origin in India. Even if there have been reports documenting the prevalence of scrub typhus in different parts of India, it is still an unknown entity, and clinicians usually do not consider it as differential diagnosis. The present study was performed to document the prevalence of scrub typhus among febrile patients in western part of Uttar Pradesh and to assess the clinical profile of infected patients on the one hand and knowledge, attitude, and practices among clinicians on the other. A total of 357 adult patients with fever of more than 5-day duration were recruited. All patients underwent complete physical examination, and detailed clinical history was elicited as per predesigned pro forma. After primary screening to rule out malaria, enteric fever, and leptospirosis infection, secondary screening for scrub typhus was done by rapid screen test and IgM ELISA. Scrub typhus infection was positive in 91 (25.5%) cases. The most common symptoms among the patients were fever (100%), pain in abdomen (79.1%), pedal edema 56 (61.5%), rash 44 (48.3%), headache 44 (48.3%), vomiting 42 (46.1%), constipation 33 (36.2%), cough 28 (30.7%), and lymphadenopathy 20 (21.9%). The median values of interleukin-8, interferon-gamma, and tumor necrosis factor-alpha in healthy controls were 15.54 pg/ml, 7.77 pg/ml, and 54.1 pg/ml, respectively, while the median values of these cytokines in scrub typhus-positive patients were 21.04 pg/ml, 8.74 pg/ml, and 73.8 pg/ml, respectively. Our results highlight that scrub typhus infection is an important cause of pyrexia of unknown origin, and active surveillance is necessary to assess the exact magnitude and distribution of the disease.

    The Law aims to define the qulifications of radiation and x-ray technicians engaging in medical treatment and to regulate so that the works are carried out properly for helping popularization and improvement of medicine and public hygiene. Persons who wish to be radiation or x-ray technicians engaging in medical treatment are required to pass the examinations for such technicians and obtain the licenes of the Minister of Health and Welfare for the former technicians and the license of a prefectural governor for the latter technicians. Mentally disordered, deaf, dumb or blind persons are excluded from licensees. Registration of such technicians, delivery of the license certificates and other related matters are provided for. The examinations are held concerning the knowledges and skills necessary for such technicians and carried out by the Minister of Health and Welfare. Persons except doctors, dentists and such technicians are prohibited to engage in the practices to apply radiation to human bodies. Restrictions on the intensity of radiation applied and the places of work are defined concerning such practices. Penal servitude of less than a year and fines less than yen 10,000 or yen 5,000 are imposed upon the violation of such prohibitions or restrictions. (Okada, K.)

    Full Text Available Orientation: Technicians are frequently promoted to supervisory positions based on their technical abilities, with scant attention focused on developing management competencies. This oversight often poses significant challenges. The effective transition from technician to supervisor is important in any organisation. Research objective: The primary objective is to identify and verify the competencies that are required for a technician and a supervisory position; the secondary objective is to identify the gap that must be filled with relevant training interventions to enable technicians to make an effective transition to a supervisory position. Motivation for this study: The identification of the management competencies required for a technician who makes a career change to a supervisor position. Research method: The sequential mixed method approach was used to enable the twophase data collection process: phase one was the quantitative phase and phase two was the qualitative phase. Main findings: The overall findings confirm that there are indeed management competencies that technicians require training and development on before being promoted to a supervisory position. Implication: Organisations need to identify the key competencies for a technician and a supervisor and implement development or training interventions that are essential to successfully transition an employee from the level of a technician to the level of a supervisor. Contribution: Organisations need to implement essential development or training interventions focused on developing management competencies and put in place support interventions such as coaching, job shadowing, mentoring and networking.

    In order to provide better programs on monitoring, early warning and prevention of Scrub Typhus in the coastal beach area, temporal-spatial distribution characteristics of scrub typhus were summarized. Relationships between temporal-spatial clustering of Scrub Typhus, meteorological factors, rodent distribution and the biological characteristics in coastal beach area of Yancheng city, were studied. Reports on network-based Scrub Typhus epidemics and information on population, weather situation through monitoring those stations, from 2005 to 2014 were collected and processed, in the coastal beach area of Yancheng city. Distribution, density of the population concerned and seasonal fluctuation on rodents were monitored in coastal beach area, from April 2011 to December, 2013. METHODS as descriptive statistics, space-time permutation scantistics, autocorrelation and Cross-correlation analysis etc, were used to analyze the temporal-spatial distribution of Scrub Typhus and correlation with rodent distribution, density fluctuation and meteorological indexes. Zero-inflated Pearson (ZIP) regression model was contributed according to the distribution of related data. All methods were calculated under Excel 2003, SPSS 16.0, Mapinfo 11.0, Satscan 9.0 and Stata/SE 10.0 softwares. (1) The incidence of Scrub Typhus was gradually increasing and the highest incidence of the year was seen in 2014, as 5.81/10 million. There was an autumn peak of Scrub typhus, with the highest incidence rate as 12.02/10 million in November. The incidence rate of Scrub typhus appeared high in Binhai, Dafeng and Xiangshui, with the average incidence rates appeared as 3.30/10 million, 3.21/10 million and 2.79/10 million, respectively. There were 12 towns with high incidence rates in the coastal beach area, with incidence rate showed between 4.41/10 and 10.03/10 million. (2) There were three incidence clusters of Scrub typhus seen in 25 towns, between October 2012 and November 2012 in Dongtai, Dafeng

    The quality of hemodialysis care has been the focus of intense scrutiny, yet little is known about the job satisfaction of the nurses and technicians providing this care. We identified 240 nurses and technicians from 307 randomly selected American facilities and asked them about (a) specific domains of job satisfaction, (b) overall job satisfaction, and (c) self-reported patient care practices. Fewer than half of nurses and technicians were satisfied with their pay or their opportunities for advancement. Almost all subjects were satisfied with their personal delivery of patient care, their chance to do things for others, and their job security. About three-fourths of nurses and technicians expressed overall satisfaction with their jobs. Higher job satisfaction was associated with increased attention to patient psychosocial and educational needs. We urge local and national associations of nurses and technicians to collaborate with dialysis facilities, chains, and regulatory agencies to address specific aspects of job satisfaction.

    Background Scrub typhus, caused by Orientia tsutsugamushi, is endemic in the Asia-Pacific region. Mortality is high if untreated, and even with treatment as high as 10–20%, further knowledge of the immune response during scrub typhus is needed. The current study was aimed at comparing plasma levels of a variety of inflammatory mediators in scrub typhus patients and controls in South India in order to map the broader cytokine profile and their relation to disease severity and clinical outcome. Methodology/Principal Findings We examined plasma levels of several cytokines in scrub typhus patients (n = 129) compared to healthy controls (n = 31) and infectious disease controls (n = 31), both in the acute phase and after recovery, by multiplex technology and enzyme immunoassays. Scrub typhus patients were characterized by marked changes in the cytokine network during the acute phase, differing not only from healthy controls but also from infectious disease controls. While most of the inflammatory markers were raised in scrub typhus, platelet-derived mediators such as RANTES were markedly decreased, probably reflecting enhanced platelet activation. Some of the inflammatory markers, including various chemokines (e.g., interleukin-8, monocyte chemoattractant peptide-1 and macrophage inflammatory protein-1β) and downstream markers of inflammation (e.g., C-reactive protein and pentraxin-3), were also associated with disease severity and mortality during follow-up, with a particular strong association with interleukin-8. Conclusions/Significance Our findings suggest that scrub typhus is characterized by a certain cytokine profile that includes dysregulated levels of a wide range of mediators, and that this enhanced inflammation could contribute to disease severity and clinical outcome.

    Cell-mediated immunity is essential in protection against rickettsial illnesses, but the role of neutrophils in these intracellular vasculotropic infections remains unclear. This study analyzed the plasma levels of nucleosomes, FSAP-activation (nucleosome-releasing factor), and neutrophil activation, as evidenced by neutrophil-elastase (ELA) complexes, in sympatric Lao patients with scrub typhus and murine typhus. In acute scrub typhus elevated nucleosome levels correlated with lower GCS scores, raised respiratory rate, jaundice and impaired liver function, whereas neutrophil activation correlated with fibrinolysis and high IL-8 plasma levels, a recently identified predictor of severe disease and mortality. Nucleosome and ELA complex levels were associated with a 4.8-fold and 4-fold increased risk of developing severe scrub typhus, beyond cut off values of 1,040 U/ml for nucleosomes and 275 U/ml for ELA complexes respectively. In murine typhus, nucleosome levels associated with pro-inflammatory cytokines and the duration of illness, while ELA complexes correlated strongly with inflammation markers, jaundice and increased respiratory rates. This study found strong correlations between circulating nucleosomes and neutrophil activation in patients with scrub typhus, but not murine typhus, providing indirect evidence that nucleosomes could originate from neutrophil extracellular trap (NET) degradation. High circulating plasma nucleosomes and ELA complexes represent independent risk factors for developing severe complications in scrub typhus. As nucleosomes and histones exposed on NETs are highly cytotoxic to endothelial cells and are strongly pro-coagulant, neutrophil-derived nucleosomes could contribute to vascular damage, the pro-coagulant state and exacerbation of disease in scrub typhus, thus indicating a detrimental role of neutrophil activation. The data suggest that increased neutrophil activation relates to disease progression and severe complications, and

    The ability of a pharmacy technician to support the patient screening and documentation-related functions of a pharmacist-driven osteoporosis management service was evaluated. A two-phase prospective study was conducted within a large integrated health system to assess a pharmacy technician's performance in supporting a multisite team of clinical pharmacy specialists providing postfracture care. In phase I of the study, a specially trained pharmacy technician provided support to pharmacists at five participating medical offices, helping to identify patients requiring pharmacist intervention and, when applicable, collecting patient-specific clinical information from the electronic health record. In phase II of the study, the amount of pharmacist time saved through the use of technician support versus usual care was evaluated. The records of 127 patient cases were reviewed by the pharmacy technician during phase I of the study, and a pharmacist agreed with the technician's determination of the need for intervention in the majority of instances (92.9%). An additional 91 patient cases were reviewed by the technician in phase II of the research. With technician support, pharmacists spent less time reviewing cases subsequently determined as not requiring intervention (mean ± S.D., 5.0 ± 3.8 minutes per case compared with 5.2 ± 4.5 minutes under the usual care model; p = 0.78). In cases requiring intervention, technician support was associated with a reduction in the average pharmacist time spent on care plan development (13.5 ± 7.1 minutes versus 18.2 ± 16.6 minutes with usual care, p = 0.34). The study results suggest that a pharmacy technician can accurately determine if a patient is a candidate for pharmacist intervention and collect clinical information to facilitate care plan development.

    The roles of pharmacy technicians are increasingly prominent given pharmacy's transition to patient-centered activities and evolving scopes of practice in many U.S. states and throughout the world. The aims of this study were to assess U.S. pharmacy technicians' self-efficacies for and attitudes toward performing current and emerging roles in hospital and in community pharmacy and to identify factors related to pharmacy technician self-efficacies in these roles. A total of 5000 pharmacy technicians from 8 U.S. states were sent an electronic survey eliciting data on current involvement, self-efficacies, and attitudes for practicing in an expansive list of practice activities. The 8 states from which the sample was drawn were selected from a stratified randomized procedure using U.S. Census Bureau geographically defined regions. Pre-notification and response reminders were employed. Data were analyzed descriptively and with univariate, inferential tests, as appropriate, to determine associations with commitment, practice environment, experience level, and other variables. Of the 612 participants who responded, 494 were currently working as a technician and not enrolled in a PharmD program of study. Participants reported various activities in which they were highly engaged. Overall, attitudes toward performing most of the activities and self-efficacies were quite favorable, even for those activities in which technicians were currently less involved. There were some notable differences between technicians practicing in community versus hospital settings. Years of experience, profession commitment, and advanced employee ranking were associated with higher levels of self-efficacy, overall. This initial examination of pharmacy technician self-efficacies identified areas that along with other factors could help employers with further expanding technician practice activities and vocational institutions with considerations for education and development of these key members

    Outpatients undergoing hemodialysis are at high risk for adverse drug events. Limited resources make it challenging for pharmacists to routinely obtain a best possible medication history (BPMH). The primary objective was to determine whether, for patients undergoing hemodialysis, a pharmacy technician has the skills to obtain a BPMH that would allow a pharmacist to identify drug-related problems. The secondary objectives were to determine the number and types of medication discrepancies and drug-related problems identified and the time required by the technician to complete the BPMH. All patients treated in the hemodialysis unit during the study period were included, except for those who required an interpreter or were unable to participate in an in-person interview. A single technician was taught how to interview patients according to a structured format. For each patient, the technician's BMPH was verified by a pharmacist. The agreement rate between technician and pharmacists was determined, along with the number and types of discrepancies and drug-related problems identified. The technician interviewed 99 patients. Of the 1334 medication orders reviewed, the technician and pharmacists agreed on all but 15 (agreement rate 98.9%). A total of 358 medication discrepancies were noted for 93 patients (3.8 discrepancies per patient). Of these, 210 (59%) were undocumented intentional discrepancies, and 148 (41%) were unintentional discrepancies (most commonly errors of commission). Of the 135 drug-related problems identified, the majority involved dosing problems or nonadherence. The technician required an average of 17 min for each interview. An adequately trained technician was capable of interviewing patients to create a BPMH. A variety of medication discrepancies and drug-related problems were identified. Generation of a BPMH by a technician is a useful approach allowing pharmacists to identify drug-related problems.

    Tai'an, a famous cultural tourist district, is a new endemic foci of scrub typhus in northern China. Frequent reports of travel-acquired cases and absence of effective vaccine indicated a significant health problem of scrub typhus in Tai'an. Thus, descriptive epidemiological methods and spatial-temporal scan statistics were used to describe the epidemic characteristics and detect the significant clusters of the high incidence of scrub typhus at the town level in Tai'an. Results of descriptive epidemiological analysis showed a total of 490 cases were reported in Tai'an with the annual average incidence ranging from 0·48 to 2·27/100 000 during 2006-2013. Females, the elderly and farmers are the high-risk groups. Monthly changes of scrub typhus cases indicated an obvious epidemic period in autumn. Spatial-temporal distribution analysis, showed significant clusters of high incidence mainly located in eastern and northern Tai'an. Our study suggests that more effective, targeted measures for local residents should be implemented in the eastern and northern areas of Tai'an in autumn. Meanwhile, it may prove beneficial for health policy makers to advise travellers to take preventive measures in order to minimize the risk of infection of scrub typhus in Tai'an.

    Scrub typhus is an infectious disease caused by Orientia tsutsugamushi-induced systemic vasculitis, but the involvement of the gastrointestinal tract and the endoscopic findings associated with scrub typhus are not well understood. We performed a prospective study and recommend performing esophagogastroduodenoscopy (EGD) for all possible scrub typhus patients, regardless of gastrointestinal symptoms. Gastrointestinal symptoms, endoscopic findings and clinical severity based on organ involvement and ICU admission were analyzed. Gastrointestinal symptoms occurred in up to 76.4% of scrub typhus patients. The major endoscopic findings were ulcers (43/127, 33.9%). Interestingly, 7.1% (9/127) of the patients presented with esophageal candidiasis. There was no correlation between the presence or absence of gastrointestinal symptoms and the endoscopic grade (P = 0.995). However, there was a positive correlation between the clinical severity and the endoscopic findings (P = 0.001). Sixty-three percent of the patients presented with erosion or ulcers on prospectively performed endoscopic evaluations, irrespective of gastrointestinal symptoms. Gastrointestinal symptoms did not reflect the need for endoscopy. Scrub typhus patients could have significant endoscopic abnormalities even in the absence of gastrointestinal symptoms.

    A descriptive study on rickettsiosis was conducted at the largest referral hospital in Hanoi, Vietnam, to identify epidemiological and clinical characteristics of specific rickettsiosis. Between March 2001 and February 2003, we enrolled 579 patients with acute undifferentiated fever (AUF), excluding patients with malaria, dengue fever, and typhoid fever, and serologically tested for Orientia tsutsugamushi and Rickettsia typhi. Of the patients, 237 (40.9%) and 193 (33.3%) had scrub and murine typhus, respectively, and 149 (25.7%) had neither of them (non–scrub and murine typhus [non-ST/MT]). The proportion of murine typhus was highest among patients living in Hanoi whereas that of scrub typhus was highest in national or regional border areas. The presence of an eschar, dyspnea, hypotension, and lymphadenopathy was significantly associated with a diagnosis of scrub typhus (OR = 46.56, 10.90, 9.01, and 7.92, respectively). Patients with murine typhus were less likely to have these findings but more likely to have myalgia, rash, and relative bradycardia (OR = 1.60, 1.56, and 1.45, respectively). Scrub typhus and murine typhus were shown to be common causes of AUF in northern Vietnam although the occurrence of spotted fever group rickettsiae was not determined. Clinical and epidemiological information may help local clinicians make clinical diagnosis of specific rickettsioses in a resource-limited setting. PMID:25778504

    Scrub typhus is a vector-borne zoonotic infection caused by Orientiatsutsugamushi. Local epidemiology of the circulating serotypes of scrub typhus is not available from most parts of India. We conducted this study for the diagnosis of scrub typhus using IgM ELISA and to detect O. tsutsugamushi serotypes circulating in southern Andhra Pradesh, India. Samples were collected from patients clinically suspected to have scrub typhus and were subjected to IgM ELISA to measure IgM antibodies against O. tsutsugamushi. Nested polymerase chain reaction (PCR) was performed targeting strain-specific regions in ELISA-positive samples. Of a total of 663 samples, 258 (38.91%) were found to be positive by IgM ELISA. Serotypes could be detected in 230 (34.69%) samples only. Only two serotypes, Karp and Kawasaki, were found in the serum samples, with the former being predominant. The dual infection of Karp and Kawasaki serotypes was found in seven patients. Other serotypes such as Gilliam, Kuroki and Kato were not detected in the samples. The nested PCR products proved useful in presumptively identifying the endemic O. tsutsugamushi serotypes. The present study could be significant in understanding scrub typhus epidemiology in this region.

    The use of catheter hub decontamination protocols is a common practice to reduce central line-associated bloodstream infections. However, few data exist on the most effective disinfection procedure prior to hub access accounting for human factors and time-dependent practices in real time in the clinical setting. An observational design with a multimodal intervention was used in this study in a neonatal intensive care unit. Direct observations on nurse compliance of scrub times with decontamination when accessing of venous catheter and feeding tube hubs were conducted during 3 phases: (1) baseline period prior to any interventions; (2) during an educational intervention phase; and (3) during a timer intervention period when using a timing device, either an actual timer or music button. Overall, both education and the timing device interventions increased the mean scrub time ± SD of venous catheter hubs. Mean baseline scrub times of 10 ± 5 seconds were lower compared with 23 ± 12 seconds after educational intervention (P music button use (P observed with scrub times of feeding tubes. Time-based infection control measures, such as scrubbing the hub, must be implemented with aids that qualify specific times to account for human factors, to ensure adherence to time-dependent measures aimed at decreasing nosocomial infections.

    The U.S. Nuclear Regulatory Commission has stated that mechanistic source term (MST) calculations are expected to be required as part of the advanced reactor licensing process. A recent study by Argonne National Laboratory has concluded that fission product scrubbing in sodium pools is an important aspect of an MST calculation for a sodium-cooled fast reactor (SFR). To model the phenomena associated with sodium pool scrubbing, a computational tool, developed as part of the Integral Fast Reactor (IFR) program, was utilized in an MST trial calculation. This tool was developed by applying classical theories of aerosol scrubbing to the decontamination of gases produced as a result of postulated fuel pin failures during an SFR accident scenario. The model currently considers aerosol capture by Brownian diffusion, inertial deposition, and gravitational sedimentation. The effects of sodium vapour condensation on aerosol scrubbing are also treated. This paper provides details of the individual scrubbing mechanisms utilized in the IFR code as well as results from a trial mechanistic source term assessment led by Argonne National Laboratory in 2016.

This study surveyed EMT instructors and medical directors to identify the most desirable core competencies for all levels of EMTs in Taiwan. Methods: A principal components analysis with Varimax rotation was conducted. An online questionnaire was distributed to obtain perspectives of EMT instructors and medical directors on the most desirable core competencies for EMTs. The target population was EMT training-course instructors and medical directors of fire departments in Taiwan. The questionnaire comprised 61 competency items, and multiple-choice and open-ended questions were used to obtain respondents’ perspectives of the Taiwanese EMT training and education system. Results: The results identified three factors at EMT-1 and EMT-2 levels and five factors at the EMT-Paramedic level. The factors for EMT-1 and EMT-2 were similar, and those for EMT-Paramedics identified further comprehensive competence perspectives. The key factors that appear to influence the development of the Taiwanese Emergency Medical Services (EMS education system are the attitude of authorities, the licensure system, and legislation. Conclusion: The findings present new core competencies for the Taiwanese EMT system and provide capacity to redesign curricula and reconsider roles for EMT-1 and EMT-2 technicians. At the EMT-Paramedic level, the findings demonstrate the importance of

    The goal of this experiment was to evaluate and compare the antimicrobial efficacy of routine preoperative hand washing using commercial medicated sponge brushes versus an alcoholic hand rub, by comparing bacterial growth on ophthalmic surgeons' hands after application of each of these methods. Twenty ophthalmic surgeons were recruited at the Hadassah-Hebrew University Medical Center in Jerusalem, Israel. Samples were collected twice from the hands of each surgeon after hand decontamination using two different protocols during routine surgical practice. The routine preparation consisted of a 3-minute surgical scrub using commercial brush-sponges incorporating either 4% chlorhexidine gluconate (CHG) or 1% povidone-iodine (PVP-I) formulations with detergent, followed by drying the hands with a sterile towel, while the 70% ethanol solution was applied for 60-seconds and allowed to air dry. Half of the group was randomly assigned to provide samples first after the routine method and the alcoholic solution a week later, and the other half of the group was sampled in the reverse order. Viable counts of bacteria were evaluated using a modified glove juice method. Bacterial colonies were enumerated after incubation for 24 hours and expressed as colony forming units (CFU)/mL for each pair of hands. Geometric mean counts were 1310 and 39 CFU/mL, in the routine and alcohol rub groups, respectively, representing a mean log 10 reduction in 1.53. The difference between the paired bacterial counts for the routine versus the alcohol rub was statistically significant (p surgical hand preparation with PVP-I and CHG in a population of practicing ophthalmic surgeons in the operative clinical setting. Thus, it provides a safe alternative as a preoperative hand disinfection method.

    Full Text Available Central aspects in the pathogenesis of scrub typhus, an infection caused by Orientia (O. tsutsugamushi, have remained obscure. Its organ and cellular tropism are poorly understood. The purpose of this study was to analyze the kinetics of bacterial dissemination and associated inflammatory responses in infected tissues in an experimental scrub typhus mouse model, following infection with the human pathogenic strain Karp. We provide a thorough analysis of O. tsutsugamushi infection in inbred Balb/c mice using footpad inoculation, which is close to the natural way of infection. By a novel, highly sensitive qPCR targeting the multi copy traD genes, we quantitatively monitored the spread of O. tsutsugamushi Karp from the skin inoculation site via the regional lymph node to the internal target organs. The highest bacterial loads were measured in the lung. Using confocal imaging, we also detected O. tsutsugamushi at the single cell level in the lung and found a predominant macrophage rather than endothelial localization. Immunohistochemical analysis of infiltrates in lung and brain revealed differently composed lesions with specific localizations: iNOS-expressing macrophages were frequent in infiltrative parenchymal noduli, but uncommon in perivascular lesions within these organs. Quantitative analysis of the macrophage response by immunohistochemistry in liver, heart, lung and brain demonstrated an early onset of macrophage activation in the liver. Serum levels of interferon (IFN-γ were increased during the acute infection, and we showed that IFN-γ contributed to iNOS-dependent bacterial growth control. Our data show that upon inoculation to the skin, O. tsutsugamushi spreads systemically to a large number of organs and gives rise to organ-specific inflammation patterns. The findings suggest an essential role for the lung in the pathogenesis of scrub typhus. The model will allow detailed studies on host-pathogen interaction and provide further

    Full Text Available Purpose: To evaluate the performances for detection of IgM and IgG antibodies to Orientia. tsutsugamushi (Ot using a gold conjugate-based rapid diagnostic test (RDT. Materials and Methods: The RDT employing mixture recombinant 56-kDa proteins of O. tsutsugamushi and the mIFA assay was performed on 33 patients from Fujian and Yunnan province respectively and 94 positive sera (36 from Hainan province and 58 from Jiangsu province from convalescent stages of the patients with scrub typhus respectively and 82 negative sera from healthy farmers from Anhui province and Beijing City respectively in 2009. A comparison of the RDT and mIFA assay was performed by using the c2 test and the P level of ≤0.05 was considered to be significant. Results: Among these 94 positive sera from convalescent stages of the illness and 82 sera from control farmers, the specificity of RDT was 100% for both IgM and IgG tests. In 33 cases with scrub typhus, 5 cases were positively detected earlier by RDT than by mIFA for the IgM test, and 2 cases were positive for the IgG test. The sensitivities of RDT were 93.9% and 90.9% for IgM and IgG, respectively. Considering IgM and IgG together, the sensitivity was 100%. The geometric mean titre (GMT of IFA and the RDT assay in diluted sera from confirmed cases were 1:37 versus 1:113 respectively (P<0.001 for IgM test and 1:99 versus 1:279 respectively (P<0.016 for IgG. Conclusions: The RDT was more sensitive than the traditional IFA for the early diagnosis of scrub typhus and was particularly suitable for use in rural areas.

    This report summarizes the results of the extraction, scrub, and strip testing for the September 2013 sampling of the Next Generation Solvent (NGS) Blended solvent from the Modular Caustic Side-Solvent Extraction Unit (MCU) Solvent Hold Tank. MCU is in the process of transitioning from the BOBCalixC6 solvent to the NGS Blend solvent. As part of that transition, MCU has intentionally created a blended solvent to be processed using the Salt Batch program. This sample represents the first sample received from that blended solvent. There were two ESS tests performed where NGS blended solvent performance was assessed using either the Tank 21 material utilized in the Salt Batch 7 analyses or a simulant waste material used in the V-5/V-10 contactor testing. This report tabulates the temperature corrected cesium distribution, or DCs values, step recovery percentage, and actual temperatures recorded during the experiment. This report also identifies the sample receipt date, preparation method, and analysis performed in the accumulation of the listed values. The calculated extraction DCs values using the Tank 21H material and simulant are 59.4 and 53.8, respectively. The DCs values for two scrub and three strip processes for the Tank 21 material are 4.58, 2.91, 0.00184, 0.0252, and 0.00575, respectively. The D-values for two scrub and three strip processes for the simulant are 3.47, 2.18, 0.00468, 0.00057, and 0.00572, respectively. These values are similar to previous measurements of Salt Batch 7 feed with lab-prepared blended solvent. These numbers are considered compatible to allow simulant testing to be completed in place of actual waste due to the limited availability of feed material.

    This study sought to document the clinical and laboratory manifestations, genetic variability, and outcomes of scrub typhus, an often severe infection caused by Orientia tsutsugamushi, in South India. Patients admitted to a large teaching hospital with IgM ELISA-confirmed scrub typhus were evaluated. Clinical examination with a thorough search for an eschar, laboratory testing, chest X-ray, and outcome were documented and analyzed. Additionally, a 410-bp region of the 56-kDa type-specific antigen gene of O. tsutsugamushi was sequenced and compared with isolates from other regions of Asia. Most of the 154 patients evaluated presented with fever and non-specific symptoms. An eschar was found in 86 (55%) patients. Mild hepatic involvement was seen in most, with other organ involvement including respiratory, cardiovascular, and renal. Multi-organ dysfunction was noted in 59 (38.3%), and the fatality rate was 7.8%. Hypotension requiring vasoactive agents was found to be an independent predictor of mortality (p<0.001). The phylogeny of 26 samples showed 17 (65%) clustering with the Kato-like group and eight (31%) with the Karp-like group. The presentation of scrub typhus can be variable, often non-specific, but with potentially severe multi-organ dysfunction. Prompt recognition is key to specific treatment and good outcomes. Further study of the circulating strains is essential for the development of a successful vaccine and sensitive point-of-care testing. Copyright © 2013 International Society for Infectious Diseases.

    Full Text Available Objective: To identify the etiology and risk factors of undifferentiated fever in a cluster of patients in Western Province, Solomon Islands, May 2014. Methods: An outbreak investigation with a case control study was conducted. A case was defined as an inpatient in one hospital in Western Province, Solomon Islands with high fever (> 38.5 °C and a negative malaria microscopy test admitted between 1 and 31 May 2014. Asymptomatic controls matched with the cases residentially were recruited in a ratio of 1:2. Serum samples from the subjects were tested for rickettsial infections using indirect micro-immunofluorescence assay. Results: Nine cases met the outbreak case definition. All cases were male. An eschar was noted in five cases (55%, and one developed pneumonitis. We did not identify any environmental factors associated with illness. Serum samples of all five follow-up cases (100% had strong-positive IgG responses to scrub typhus. All but one control (10% had a moderate response against scrub typhus. Four controls had low levels of antibodies against spotted fever group rickettsia, and only one had a low-level response to typhus group rickettsia. Discussion: This outbreak represents the first laboratory-confirmed outbreak of scrub typhus in the Western Province of Solomon Islands. The results suggest that rickettsial infections are more common than currently recognized as a cause of an acute febrile illness. A revised clinical case definition for rickettsial infections and treatment guidelines were developed and shared with provincial health staff for better surveillance and response to future outbreaks of a similar kind.

    Traditionally, pharmacy technicians have worked alongside pharmacists in community and hospital pharmacy. Changes within pharmacy provide opportunity for role expansion and with no apparent career pathway, there is a need to define the current pharmacy technician role and role in medicines optimisation. To capture the current roles of pharmacy technicians and identify how their future role will contribute to medicines optimisation. Following ethical approval and piloting, an online survey to ascertain pharmacy technicians' views about their roles was undertaken. Recruitment took place in collaboration with the Association of Pharmacy Technicians UK. Data were exported to SPSS, data screened and descriptive statistics produced. Free text responses were analysed and tasks collated into categories reflecting the type of work involved in each task. Responses received were 393 (28%, n = 1380). Results were organised into five groups: i.e., hospital, community, primary care, General Practitioner (GP) practice and other (which included HM Prison Service). Thirty tasks were reported as commonly undertaken in three or more settings and 206 (84.7%, n = 243) pharmacy technicians reported they would like to expand their role. Tasks core to hospital and community pharmacy should be considered for inclusion to initial education standards to reflect current practice. Post qualification, pharmacy technicians indicate a significant desire to expand clinically and managerially allowing pharmacists more time in patient-facing/clinical roles.

    To describe pharmacy technician training programs in the United States and to compare pharmacy technician program characteristics between programs with and without a pharmacist on faculty and between programs with different accreditation status. Descriptive, cross-sectional study. Not applicable. United States pharmacy technician programs. Not applicable. Student class size, faculty credentials, coursework components, program length, tuition rates, and admission criteria. Currently, there are more than 698 pharmacy technician programs across 1114 campuses, with complete data available for 216 programs. Programs varied widely in terms of class sizes, faculty credentials, and admission criteria. Programs with pharmacists on faculty were significantly less expensive than were those without pharmacists (P = 0.009). Accreditation had no impact on tuition prices. This is the first study of its kind to describe and characterize pharmacy technician training programs. There is relatively little control of technician training by the profession of pharmacy. The quality of these programs in terms of student outcomes is unknown, and it should be explored. Rigorous debate and discussion is needed regarding the future of pharmacy technician roles and the training required for those roles. Copyright © 2016 American Pharmacists Association®.

    Scrub typhus immunogens were prepared from Rickettsia tsutsugamushi strains Karp, Kato, Gilliam, Kostival, and Buie by exposing frozen infected yolk sac suspensions to 300 krad of gamma radiation. Mouse protection tests showed that each of the irradiated immunogens protected C3H/HeDub mice against high challenge levels of Karp and Gilliam, but that none of these single-strain immunogens were capable of protecting against all five of the challenge strains. Broad-spectrum protection was achieved by using combinations of three strains of irradiated rickettsiae in a vaccination regimen of three injections at 5-day intervals

Even though pool scrubbing has been traditionally associated with low injection velocities, there are a number of potential scenarios in which fission product trapping in aqueous ponds might also occur under jet injection regime (like SGTR meltdown sequences in PWRs and SBO ones in BWRs). The SPARC90 code was developed to determine the fission product trapping in pools during severe accidents. The code assumes that carrier gas arrives at the water ponds at low or moderate velocities and it forms a big bubble that eventually detaches from the injection pipe. However, particle laden gases may enter the water at very high velocities resulting in a submerged gas jet instead. This work presents the fundamentals, major hypotheses and changes introduced into the code in order to estimate particle removal during gas injection in pools under the jet regime (SPARC90-Jet). A simplified and reliable approach to submerged jet hydrodynamics has been implemented on the basis of updated equations for jet hydrodynamics and aerosol removal, so that gas–liquid and droplet-particles interactions are described. The code modifications have been validated as far as possible. However, no suitable hydrodynamic tests have been found in the literature, so that an indirect validation has been conducted through comparisons against data from pool scrubbing experiments.

    In health care simulation, simulation technicians perform multiple tasks to support various educational offerings. Technician responsibilities and the tasks that accompany them seem to vary between centers. The objectives were to identify the range and frequency of tasks that technicians perform and to determine if there is a correspondence between what technicians do and what they feel their responsibilities should be. We hypothesized that there is a core set of responsibilities and tasks for the technician position regardless of background, experience, and type of simulation center. We conducted a prospective, survey-based study of individuals currently functioning in a simulation technician role in a simulation center. This survey was designed internally and piloted within 3 academic simulation centers. Potential respondents were identified through a national mailing list, and the survey was distributed electronically during a 3-week period. A survey request was sent to 280 potential participants, 136 (49%) responded, and 73 met inclusion criteria. Five core tasks were identified as follows: equipment setup and breakdown, programming scenarios into software, operation of software during simulation, audiovisual support for courses, and on-site simulator maintenance. Independent of background before they were hired, technicians felt unprepared for their role once taking the position. Formal training was identified as a need; however, the majority of technicians felt experience over time was the main contributor toward developing knowledge and skills within their role. This study represents a first step in defining the technician role within simulation-based education and supports the need for the development of a formal job description to allow recruitment, development, and certification.

    The purpose of this paper is to provide basic data in order to systematize the management of demand and supply of radiologic technicians, to pursue a fair regional distribution of educational institutions, and furthermore to keep reasonable medical treatment and fee. This research was carried out through the investigation of radiologic equipment and technicians according to the distribution of the population. We compared and analyzed the correlation between regional population, the number of clinics and hospitals, the number of medical imaging devices, and the number of radiologists and radiologic technicians in 5 cities without 'Gu' administrative units in 2008. 27,317 radiologic technicians have been produced since the administration of the national qualifying exam for radiologic technicians. About 18,000 radiologic technicians are currently working. There are 39 colleges or universities with Departments of Radiology and the admission quota is 2,120 students excluding one college. The ratio of radiologic equipment to radiologic technicians is 2.6 to 1. There is a dilemma in which some radiologic technicians fail to find appropriate jobs while some clinics or hospitals are in need of radiologic technicians. This dilemma is due to unreasonable regional discrepancies in pay system and welfare situation, and excessive profit-oriented recruiting system of clinics and hospitals. The increase of students of Radiologic Departments and approval of additional departments will end up with producing superfluous high academic degree holders, which is on the contrary to the government policy to produce more job opportunities. So the policy of increasing Radiologic Departments should be reconsidered.

  8. Guidebook on the education and training of technicians for nuclear power

    1989-01-01

    The IAEA Guidebook on the Education and Training of Technicians for Nuclear Power aims to assist Member States, especially the developing countries which are in the process of implementing, or intending to implement, a nuclear power programme, to understand and meet their requirements for qualified technicians in the most effective and efficient manner. It specifically seeks to assist policy makers and planners, as well as those designing and implementing education and training programmes. In this Guidebook, technician level occupations include those filled by technicians and higher level technicians (techniciens superieurs or technologists) and also by non-graduate engineers. The Guidebook complements the IAEA Guidebook on Manpower Development for Nuclear Power, as well as the IAEA Guidebook on the Qualification of Nuclear Power Plant Operations Personnel. The key objectives of this Guidebook are to describe: (1) the level and content of conventional education and training which a technician must have before nuclear oriented education and training can begin; (2) the level and content of nuclear oriented education and training; (3) measures to bridge the gap between the education and training acquired by technicians in the national technical schools (i.e. the level attained before upgrading) and the level of education and training qualifications needed for technicians to work in the nuclear power programme (i.e. the level attained after completion of nuclear oriented education and training). Valuable information on the national experiences of IAEA Member States in the education and training of technicians for nuclear power, as well as examples of such education and training from various Member States, are included in IAEA-TECDOC-526, which should be read in conjunction with the present text. 3 refs, 13 figs, 3 tabs

    A technician at AeroVironment's Design Development Center in Simi Valley, California, checks a panel of silicon solar cells for conductivity and voltage. The bi-facial cells, fabricated by SunPower, Inc., of Sunnyvale, California, are among 64,000 solar cells which have been installed on the Helios Prototype solar-powered aircraft to provide power to its 14 electric motors and operating systems. Developed by AeroVironment under NASA's Environmental Research Aircraft and Sensor Technology (ERAST) project, the Helios Prototype is the forerunner of a planned fleet of slow-flying, long duration, high-altitude aircraft which can perform atmospheric science missions and serve as telecommunications relay platforms in the stratosphere. Target goals set by NASA for the giant 246-foot span flying wing include reaching and sustaining subsonic horizontal flight at 100,000 feet altitude in 2001, and sustained continuous flight for at least four days and nights above 50,000 feet altitude with the aid of a regenerative fuel cell-based energy storage system now under development in 2003.

  10. Management perceptions of the Health Physics Technician job

    Mazour, T.J.; Marotta, F.J.

    1985-12-01

    In 1984, an industry-wide job analysis of nuclear power reactor Health Physics Technicians (HPTs) was completed. These results provided the basis for job descriptions, industry-wide task listings and recommendations for task selections for further analysis and formal training. A total of 389 tasks were identified and reviewed by 850 HPTs representing 39 plants and 6 vendor companies. Constructive criticism of the HPT job analysis focused on the fact that HPT supervisors and managers were not included in the survey. Concerns were addressed that these supervisors/managers might have a divergent perception of the HPT job that could lead to different conclusions than those that were originally drawn. The only way to confirm (or deny) this hypothesis was to verify the results of the job analysis of HPTs by also surveying radiation protection management personnel. A total of 19 HPT supervisors/managers completed the same survey that had been used for HPT job incumbents. They were asked to rate each task on the basis of their job incumbents' performance of the task. Of the 1161 ratings (389 tasks each with a rating for frequency, difficulty, and importance), only 37 of the ratings differed between the HPTs and the HPT supervisors/managers (at the 99% confidence level)

    Elder abuse and neglect are highly under-reported in the United States. This may be partially attributed to low incidence of reporting among emergency medical technicians' (EMTs), despite state-mandated reporting of suspected elder abuse. Innovative solutions are needed to address under-reporting. The objective was to describe EMTs' experience detecting and reporting elder abuse. Qualitative data were collected from 11 EMTs and 12 Adult Protective Services (APS) caseworkers that participated in one of five semi-structured focus groups. Focus group data were iteratively coded by two coders. Findings suggest a number of barriers prevent EMTs from reporting elder abuse to APS. Participants suggested that limited training on elder abuse detection or reporting has been provided to them. EMTs suggested that training, creation of an automated reporting system or brief screening tool could be used to enhance EMT's ability to detect and communicate suspected cases of elder abuse to APS. Results from the present study suggest that EMTs may be uniquely situated to serve as elder abuse and neglect surveillance personnel. EMTs are eager to work with APS to address the under-reporting of elder abuse and neglect, but training is minimal and current reporting procedures are time-prohibitive given their primary role as emergency healthcare providers. Future studies should seek to translate these findings into practice by identifying specific indicators predictive of elder abuse and neglect for inclusion on an automated reporting instrument for EMTs.

    Since the working medical personnel including dentists and dental technicians mainly use their hands, it is understandable that the most common occupational disease amongst medical personnel is contact dermatitis (CD) (80%-90% of cases). Development of occupational CD is caused by contact of the skin with various substances in occupational environment. Occupational etiologic factors for dental personnel are foremost reactions to gloves containing latex, followed by various dental materials (e.g., metals, acrylates), detergents, lubricants, solvents, chemicals, etc. Since occupational CD is relatively common in dental personnel, its timely recognition, treatment and taking preventive measures is needed. Achieving skin protection at exposed workplaces is of special importance, as well as implementing necessary measures consequently and sufficiently, which is sometimes difficult to achieve. Various studies have shown the benefit of applying preventive measures, such as numerous protocols for reducing and managing latex sensitivity and other forms of CD in dentistry. Active involvement of physicians within the health care system, primarily dermatologists, occupational medicine specialists and general medicine doctors is needed for establishing an accurate medical diagnosis and confirmation of occupational skin disease.

    Full Text Available Effective workplace-based interventions after critical incidents (CIs are needed for emergency medical technicians (EMT/paramedics. The evidence for a period out of service post-CI (downtime is sparse; however it may prevent posttraumatic stress disorder (PTSD and burnout symptoms. We examined the hypothesis that downtime post-CI is associated with fewer symptoms of four long-term emotional sequelae in EMT/paramedics: depression, PTSD, burnout, and stress-related emotional symptoms (accepted cut-offs defined high scores. Two hundred and one paramedics completed questionnaires concerning an index CI including downtime experience, acute distress, and current emotional symptoms. Nearly 75% received downtime; 59% found it helpful; 84% spent it with peers. Downtime was associated only with lower depression symptoms, not with other outcomes. The optimal period for downtime was between 1 day being less effective. Planned testing of mediation of the association between downtime and depression by either calming acute post-CI distress or feeling helped by others was not performed because post-CI distress was not associated with downtime and perceived helpfulness was not associated with depression. These results suggest that outcomes of CIs follow different pathways and may require different interventions. A brief downtime is a relatively simple and effective strategy in preventing later depression symptoms.

    The frequency of hypoxanthine phosphoribosyl transferase (HPRT) mutants among peripheral T-lymphocytes of radiotherapy technicians primarily exposed to 60Co was measured by the T-cell cloning method. Mutant frequencies of these technicians in 1984 and 1986 were significantly higher than those of physiotherapy technicians who worked in a neighboring service, and correlated significantly with thermoluminescence dosimeter readings recorded during the 6 mo preceding mutant frequency determination. Correlations decreased when related to dose recorded over longer time intervals. HPRT mutant frequency determination in peripheral lymphocytes is a good measure of recently received biologically effective radiation dose in an occupationally exposed population

    Full Text Available Background: Dental laboratory technician is one of the professions in which dust exposure is frequently experienced and therefore the health of workers has to be monitored. Aims: In this study, changes in the pulmonary functions and of pneumoconiosis frequencies among dental technicians after five years were investigated by comparing the results of two screenings carried out in 2008 and 2013. Study Design: Cohort study. Methods: In 2008 and 2013, Provincial Health Directorate carried out two different health screenings covering all of the dental technicians working in dental laboratories in Denizli. In both screenings, a questionnaire was applied, with which socio-demographic and workplace properties of the technicians were obtained. In addition, Pulmonary function tests (PFT and standard chest X-rays of the technicians were performed. The results of these two screenings were evaluated by a chest specialist, and physical examinations were performed as necessary. In 2013, technicians who had pathologies underwent computerized tomography (HRCT. In this study, the study group was composed of dental laboratory technicians that participated in both screenings (2008 and 2013 and the data obtained from the screenings were compared. The gathered data were analyzed using paired student-t and X2 tests. Results: A total of 125 dental laboratory technicians participated in the two screenings. Overall, 92% of the technicians were male and the mean age of the participants was 35. Technicians were working for 9 hours a day, 6 days a week. Total exposure time was calculated to be around 41 thousand hours. Approximately 60% of workers were smokers. When the results of PFT were analyzed, 73% of the first evaluations were found to be normal; however, this ratio decreased to 51% in the second analysis five years later. In the second PFT measurement, compared to the first, there was a 23% decrease in the forced vital capacity (FVC value, and a 15.7% decrease in

    An Extraction, Scrub, and Strip (ESS) test was performed on a sample of Salt Waste Processing Facility (SWPF) Caustic-Side Solvent Extraction (CSSX) solvent and salt simulant to determine cesium distribution ratios (D(Cs)), and cesium concentration in the strip effluent (SE) and decontaminated salt solution (DSS) streams; this data will be used by Parsons to help determine if the solvent is qualified for use at the SWPF. The ESS test showed acceptable performance of the solvent for extraction, scrub, and strip operations. The extraction D(Cs) measured 12.5, exceeding the required value of 8. This value is consistent with results from previous ESS tests using similar solvent formulations. Similarly, scrub and strip cesium distribution ratios fell within acceptable ranges. This revision was created to correct an error. The previous revision used an incorrect set of temperature correction coefficients which resulted in slight deviations from the correct D(Cs) results.

    Scrub typhus, an acute febrile illness that is widespread in the Asia-Pacific region, is caused by the bacterium Orientia tsutsugamushi, which displays high levels of antigenic variation. We conducted an investigation to identify the circulating genotypes of O. tsutsugamushi in 3 scrub typhus-endemic geographic regions of India: South India, Northern India, and Northeast India. Eschar samples collected during September 2010-August 2012 from patients with scrub typhus were subjected to 56-kDa type-specific PCR and sequencing to identify their genotypes. Kato-like strains predominated (61.5%), especially in the South and Northeast, followed by Karp-like strains (27.7%) and Gilliam and Ikeda strains (2.3% each). Neimeng-65 genotype strains were also observed in the Northeast. Clarifying the genotypic diversity of O. tsutsugamushi in India enhances knowledge of the regional diversity among circulating strains and provides potential resources for future region-specific diagnostic studies and vaccine development.

    The biggest biomass source in Malaysia comes from oil palm industry. According to the statistic of year 2004, Malaysia produced 40 million tones per year of biomass which 30 million tones of biomass originated from the oil palm industries. Therefore, the biomass waste such as palm kernel shell can be used to produce granular adsorbent for radioactive materials. For that reason, a newly system, called Rocking Kiln - Fluidized Bed (RK - FB) was developed to utilize large amount of the biomass to produce high value added product. Charcoal or chemically produced activated carbon could be produced by using the kiln. Washing process was introduced to remove particles, minerals and volatile matters from charcoal produced and then would create more surface area in the adsorbent by creating more active sites. In this research, the adsorbent produced was used to scrub iodine 131. In nuclear power reactor, iodine isotope 131 is produced during nuclear fission, and this elementary radioactive iodine may pollute exhaust air streams that could cause thyroid cancer. For removal of radioactive iodine, normally a potassium iodide - impregnated activated carbon (KI - AC) is used. Thus, a process will be developed to produce KI - AC and this product will be used to calculate the efficiency to remove the radioactive iodine 131.The results obtain show that adsorbent produced has a high potential to be used in radioactive adsorbing and likely more economics. This paper will elaborate further the experimental set-up of in Kiln - Fluidized Bed (RK - FB), adsorbent quality and radioactive scrubbing process. (author)

  4. POSSIBILITY OF BENEFICIATION OF SILICA SAND FROM THE CROATIAN DEPOSITS USING ATTRITION SCRUBBING

    Full Text Available To meet high quality requirements defined for specific industrial applications, the raw sand often has to be subjected to extensive physical and chemical processing. The possibility of achieving silica sand concentrate of required quality depends mostly on raw sand properties, primarily mineral impurity types and contents, and features of applied beneficiation methods. When the impurities occur in the form of oxide coatings on the surfaces of the single sand grains, attriton scrubbing is applied. By reducing the proportion of oxide coatings on the grains, the quality of sand can be improved. With the aim to determine the possibilities of the beneficiation of silica sand from significant Croatian deposits (“Vrtlinska”, “Štefanac” and “Španovica” and achieve concentrate grade complying with the requirements of domestic industry, laboratory tests were conducted on three raw sand samples with different SiO2 and impurity contents. Grain size distribution, chemical and mineral composition of raw sand samples, and the possibility of their quality improvement by applying the washing, classification and attrition scrubbing were defined by analysis of test results (the paper is published in Croatian.

  5. Effects of high fire frequency in creosote bush scrub vegetation of the Mojave Desert

    Plant invasions can increase fire frequency in desert ecosystems where fires were historically infrequent. Although there are many resource management concerns associated with high frequency fire in deserts, fundamental effects on plant community characteristics remain largely unstudied. Here I describe the effects of fire frequency on creosote bush scrub vegetation in the Mojave Desert, USA. Biomass of the invasive annual grass Bromus rubens L. increased following fire, but did not increase further with additional fires. In contrast, density, cover and species richness of native perennial plants each decreased following fire and continued to decrease with subsequent fires, although not as dramatically as after the initial fire. Responses were similar 5 and 14 years post-fire, except that cover of Hymenoclea salsola Torr. & A. Gray and Achnatherum speciosa Trin. & Rupr. both increased in areas burnt once. These results suggest that control of B. rubens may be equally warranted after one, two or three fires, but revegetation of native perennial plants is most warranted following multiple fires. These results are valid within the scope of this study, which is defined as relatively short term vegetation responses (???14 years) to short fire return intervals (6.3 and 7.3 years for the two and three fire frequency levels) within creosote bush scrub of the Mojave Desert. ?? 2012 IAWF.

    This is a qualitative, exploratory and descriptive study whose general objective was to learn, considering the perspective of the nursing technician who works in school hospitals, the competencies developed during their educational process to implement the Nursing Care Systematization (NCS). Data collection and analysis were carried out through a focal group, with content analysis and nursing technicians. Two thematic categories emerged: The participation of the nursing technician in the NCS and The competencies in the education of the nursing technician. Each one received two subcategories: Conception of the NCS and (De)valuation of the NCS, Technical-scientific competency and Competency in the interpersonal relationship, respectively. It was observed that the NCS must be shared, discussed and made public among nursing professionals, so that they may acknowledge themselves as the leading actors of their methodology and be aware that their practices determine the results.

    To describe nontraditional roles for Certified Pharmacy Technicians (CPhTs) within pharmaceutical industry. Drug information department within a large biotechnology/pharmaceutical organization. The Medical Communications department within Genentech uses a skills-mix staffing model in which employees with varying educational and training backgrounds work as a team on meeting the informational needs of consumers and health professionals who contact the company. One position within the department is that of Medical Communications Associate, responsible primarily for managing product inquiries. Medical Communications Associates have degrees in life sciences or an equivalent combination of education and experience, including a minimum of 2 years of related experience in the health care industry. Currently, four of the seven Medical Communications Associates in the department are CPhTs. Not applicable. Ability to recruit CPhTs for Medical Communications Associate positions, and job satisfaction of those hired into these positions. Critical basic skills needed for the Medical Communications Associate position include strong computer literacy, ability to multitask, and ability to work in an environment with frequent interruptions. Strong oral and written communications skills, customer service skills, ability to deal with stressful situations, product-specific knowledge, ability to work on a daily basis with Medical Communications Pharmacists, and knowledge of medical terminology are also important. The skills set of CPhTs matches these requirements, as evidenced by the experiences of the four staff members who have worked in the department for a total of 17 person-years. This nontraditional role for CPhTs can be rewarding and beneficial to all, affording an unique opportunity within the pharmaceutical industry. The skill set and experience of CPhTs can be used in the nontraditional pharmacy practice setting of drug information.

    We sought to develop a reliable and valid tool for measuring teamwork among emergency medical technician (EMT) partnerships. We adapted existing scales and developed new items to measure components of teamwork. After recruiting a convenience sample of 39 agencies, we tested a 122-item draft survey tool (EMT-TEAMWORK). We performed a series of exploratory factor analyses (EFAs) and confirmatory factor analysis (CFA) to test reliability and construct validity, describing variation in domain and global scores using descriptive statistics. We received 687 completed surveys. The EFAs identified a nine-factor solution. We labeled these factors 1) Team Orientation, 2) Team Structure & Leadership, 3) Partner Communication, Team Support, & Monitoring, 4) Partner Trust and Shared Mental Models, 5) Partner Adaptability & Back-Up Behavior, 6) Process Conflict, 7) Strong Task Conflict, 8) Mild Task Conflict, and 9) Interpersonal Conflict. We tested a short-form (30-item SF) and long-form (45-item LF) version. The CFAs determined that both the SF and the LF possess positive psychometric properties of reliability and construct validity. The EMT-TEAMWORK-SF has positive internal consistency properties, with a mean Cronbach's alpha coefficient ≥0.70 across all nine factors (mean = 0.84; minimum = 0.78, maximum = 0.94). The mean Cronbach's alpha coefficient for the EMT-TEAMWORK-LF was 0.87 (minimum = 0.79, maximum = 0.94). There was wide variation in weighted scores across all nine factors and the global score for the SF and LF. Mean scores were lowest for the Team Orientation factor (48.1, standard deviation [SD] 21.5, SF; 49.3, SD 19.8, LF) and highest (more positive) for the Interpersonal Conflict factor (87.7, SD 18.1, for both SF and LF). We developed a reliable and valid survey to evaluate teamwork between EMT partners.

    Statement of the problem Digital workflows (CAD/CAM) have been introduced in dentistry during recent years. No published information exists on dental technicians' use and reporting of this technology.Purpose The aim of this cross sectional survey was to identify the extent digital technology has infiltrated the workplace and to investigate the factors affecting the use of CAD-CAM technology by dental laboratory technicians within Ireland and the UK.Materials and methods A web-based questionnaire was composed (Opinio, Object Planet Inc. Oslo, Norway) and distributed to UK and Irish dental technicians. Answers to all questions were anonymous and grouped such that general information was gathered initially, followed by branching of the survey into two sections depending on whether or not the respondent worked with CAD-CAM technology. Results were compiled and statistical analysis (Fisher's Exact test, SPSS, IBM, Armonk, New York, USA) was performed in order to investigate any correlation between various demographic variables and the answers provided.Results The survey was distributed to 760 UK technicians and 77 Irish technicians. The total number of completed surveys was 105, which yielded a total response rate of 14%. Most technicians reported using some form of CAD/CAM aspect in the workflow, and this was more significant for technicians working in large laboratories. Most training received was company-led. Large laboratories were also significantly correlated with less outsourcing of CAD/CAM work and a change in dental material use leading to the increase of zirconia and the decrease of noble alloys. Dental technicians did not report any significant change in working relationships and staffing as a result of CAD/CAM incorporation. High initial investment cost was the most common reason quoted from non-users, along with the lack of such technology in their working environment.

    Full Text Available Objectives: The aim of this 7-year follow-up study was to determine respiratory changes in dental technicians. Material and Methods: In our region, in the year 2005, 36 dental technicians were evaluated with a cross-sectional study on respiratory occupational diseases, and in 2012 we evaluated them again. Inclusion of information on respiratory symptoms and demographic features questionnaires was applied. Pulmonary function tests (PFT were performed. Chest X-rays (CXR were evaluated according to the ILO-2000 classification. For the comparisons of the technicians' findings in 2005 and 2012, data analyses were performed with the Wilcoxon test in addition to descriptive statistical procedures. Results: In 2012, 19 out of the 36 technicians continued to work in the same place, so we were able to evaluate their findings. The prevalence of respiratory symptoms in dental technician was as follows: dyspnea 7 (37%, cough 6 (32%, and phlegm 5 (26%. According to ILO classifications in 2005, among the 36 technicians, 5 (13.8% had pneumoconiosis. At the end of 7 years, there were 9 pneumoconiosis cases among the 19 remaining technicians (47%. Thus, there was a statistically significant progression on the profusion of the radiologic findings (p < 0.005. Also there was a significant worsening on spirometric findings (p < 0.05. Conclusion: In dental technicians, a determination of both radiologic and functional progressions at the end of 7 years demonstrate that the primary and secondary preventive measures are necessary for these workplaces. Workplaces must be regularly controlled for worker health and hygiene.

    Background: Traditionally, pharmacy technicians have worked alongside pharmacists in community and hospital pharmacy. Changes within pharmacy provide opportunity for role expansion and with no apparent career pathway, there is a need to define the current pharmacy technician role and role in medicines optimisation. Aim: To capture the current roles of pharmacy technicians and identify how their future role will contribute to medicines optimisation. Methods: Following ethical approval and piloting, an online survey to ascertain pharmacy technicians’ views about their roles was undertaken. Recruitment took place in collaboration with the Association of Pharmacy Technicians UK. Data were exported to SPSS, data screened and descriptive statistics produced. Free text responses were analysed and tasks collated into categories reflecting the type of work involved in each task. Results: Responses received were 393 (28%, n = 1380). Results were organised into five groups: i.e., hospital, community, primary care, General Practitioner (GP) practice and other (which included HM Prison Service). Thirty tasks were reported as commonly undertaken in three or more settings and 206 (84.7%, n = 243) pharmacy technicians reported they would like to expand their role. Conclusions: Tasks core to hospital and community pharmacy should be considered for inclusion to initial education standards to reflect current practice. Post qualification, pharmacy technicians indicate a significant desire to expand clinically and managerially allowing pharmacists more time in patient-facing/clinical roles. PMID:28970452

  17. Training and qualification of health and safety technicians at a national laboratory

    Over the last 30 years, Lawrence Livermore National Laboratory (LLNL) has successfully implemented the concept of a multi-disciplined technician. LLNL Health and Safety Technicians have responsibilities in industrial hygiene, industrial safety, health physics, as well as fire, explosive, and criticality safety. One of the major benefits to this approach is the cost-effective use of workers who display an ownership of health and safety issues which is sometimes lacking when responsibilities are divided. Although LLNL has always promoted the concept of a multi-discipline technician, this concept is gaining interest within the Department of Energy (DOE) community. In November 1992, individuals from Oak Ridge Institute of Science and Education (ORISE) and RUST Geotech, joined by LLNL established a committee to address the issues of Health and Safety Technicians. In 1993, the DOE Office of Environmental, Safety and Health, in response to the Defense Nuclear Facility Safety Board Recommendation 91-6, stated DOE projects, particularly environmental restoration, typically present hazards other than radiation such as chemicals, explosives, complex construction activities, etc., which require additional expertise by Radiological Control Technicians. They followed with a commitment that a training guide would be issued. The trend in the last two decades has been toward greater specialization in the areas of health and safety. In contrast, the LLNL has moved toward a generalist approach integrating the once separate functions of the industrial hygiene and health physics technician into one function

    Under the 2003 Health Practitioners Competence Assurance (HPCA) Act, New Zealand registered dental technicians are subject to mandatory Continuing Professional Development (CPD) requirements. Internationally, little published literature has examined dental technicians' perspectives of CPD and CPD needs, and there is no published literature relating to the New Zealand context. Available research highlights the importance of CPD for maintaining high professional standards, ensuring patient safety, allowing dental technicians to keep abreast of current research and technological advances, fostering peer networks, and promoting job satisfaction. In 2009, an online open-ended questionnaire was developed to examine New Zealand dental and clinical dental technicians' perspectives of CPD and their perceived CPD needs. In total, 45 New Zealand registered dental technicians responded. Questionnaire responses provided rich qualitative insights into dental technicians' wide-ranging perceptions of CPD, factors that make CPD involvement more or less difficult and more or less desirable, and ways in which CPD access and relevance might be improved. This paper discusses the survey findings in the light of the existing literature on CPD and in relation to the unique New Zealand regulatory environment. It highlights the factors which respondents identified as shaping their CPD decisions, barriers to CPD engagement, perceived CPD needs, suggestions as to how the current CPD system could be improved, and areas for future research.

    Tech-check-tech (TCT) is a practice model in which pharmacy technicians with advanced training can perform final verification of prescriptions that have been previously reviewed for appropriateness by a pharmacist. Few states have adopted TCT in part because of the common view that this model is controversial among members of the profession. This article aims to summarize the existing research on pharmacist and technician perceptions of community pharmacy-based TCT. A literature review was conducted using MEDLINE (January 1990 to August 2016) and Google Scholar (January 1990 to August 2016) using the terms "tech* and check," "tech-check-tech," "checking technician," and "accuracy checking tech*." Of the 7 studies identified we found general agreement among both pharmacists and technicians that TCT in community pharmacy settings can be safely performed. This agreement persisted in studies of theoretical TCT models and in studies assessing participants in actual community-based TCT models. Pharmacists who had previously worked with a checking technician were generally more favorable toward TCT. Both pharmacists and technicians in community pharmacy settings generally perceived TCT to be safe, in both theoretical surveys and in surveys following actual TCT demonstration projects. These perceptions of safety align well with the actual outcomes achieved from community pharmacy TCT studies.

    The growing interest in technicians' workloads research is probably associated with the recent surge in competition. This was prompted by unprecedented technological development that triggers changes in customer tastes and preferences for industrial goods. In a quest for business improvement, this worldwide intense competition in industries has stimulated theories and practical frameworks that seek to optimise performance in workplaces. In line with this drive, the present paper proposes an optimisation model which considers technicians' reliability that complements factory information obtained. The information used emerged from technicians' productivity and earned-values using the concept of multi-objective modelling approach. Since technicians are expected to carry out routine and stochastic maintenance work, we consider these workloads as constraints. The influence of training, fatigue and experiential knowledge of technicians on workload management was considered. These workloads were combined with maintenance policy in optimising reliability, productivity and earned-values using the goal programming approach. Practical datasets were utilised in studying the applicability of the proposed model in practice. It was observed that our model was able to generate information that practicing maintenance engineers can apply in making more informed decisions on technicians' management.

    Introduction: Several studies have evaluated the efficacy of home use of chlorhexidine before surgery to reduce bacterial colonization. However, these studies have provided conflicting evidence about the potential efficacy of this strategy in decreasing bacterial loads and infection rates across surgical populations, and no prior study has analyzed the benefit of this intervention before spine surgery. We prospectively analyzed the effectiveness of chlorhexidine gluconate wipes for decreasing bacterial counts on the posterior neck. Methods: Sixteen healthy adults participated in this prospective study. The right side of each participant’s neck was wiped twice (the night before and the morning of the experiment) with chlorhexidine gluconate wipes. The left side was used as the control region. Bacterial swabs were obtained as a baseline upon enrollment in the study, then upon arrival at the hospital, and, finally, after both sides of the neck had received standard preoperative scrubbing. Results: All patients had positive baseline bacterial growth (median >1,000 colonies/mL). When chlorhexidine gluconate wipes were used, decreased bacterial counts were noted before the preoperative scrub, but this finding was not statistically significant (P = 0.059). All patients had zero bacteria identified on either side of their neck after completion of the preoperative scrub. Conclusion: At-home use of chlorhexidine gluconate wipes did not decrease the topical bacterial burden. Therefore, using chlorhexidine gluconate wipes at home before surgery may offer no added benefit. PMID:29227322

    Age can affect the clinical features and severity of infectious disorders, such as scrub typhus. We performed this study to examine differences between elderly and non-elderly scrub typhus patients, and to identify risk factors predictive of disease outcomes. This retrospective study included patients admitted to a tertiary hospital with scrub typhus between 2001 and 2011. A total of 615 patients were enrolled in this study, 328 of which were >65 years of age. Of the elderly patients, 46.0% (151/328) experienced at least one complication compared to only 23.0% (66/287) in younger patients. A linear trend was observed between age and complication rates (p=0.002). The most common complication in elderly patients was acute kidney injury (75, 22.9%). Treatment failure was reported in 10 elderly patients (3.0%) compared to one non-elderly patient (0.3%). Mental confusion and dyspnea of clinical manifestations at admission were common in elderly patients. Frequency of fever, rash, and eschar were similar in both groups. The following four factors were significantly associated with severe scrub typhus in elderly patients: (1) white blood cell (WBC) counts>10,000/mm(3) (OR=2.569, CI=1.298-5.086), (2) MDRD GFR10 points (OR=3.304, CI=1.793-60.87). Complications and mortality were more common in elderly patients, often associated with delays in diagnosis and treatment. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

    There is an urgent need to develop rapid and accurate point-of-care (POC) technologies for acute scrub typhus diagnosis in low-resource, primary health care settings to guide clinical therapy. In this study we present the clinical evaluation of loop-mediated isothermal PCR assay (LAMP) in the context of a prospective fever study, including 161 patients from scrub typhus-endemic Chiang Rai, northern Thailand. A robust reference comparator set comprising following 'scrub typhus infection criteria' (STIC) was used: a) positive cell culture isolate and/or b) an admission IgM titer ≥1∶12,800 using the 'gold standard' indirect immunofluorescence assay (IFA) and/or c) a 4-fold rising IFA IgM titer and/or d) a positive result in at least two out of three PCR assays. Compared to the STIC criteria, all PCR assays (including LAMP) demonstrated high specificity ranging from 96-99%, with sensitivities varying from 40% to 56%, similar to the antibody based rapid test, which had a sensitivity of 47% and a specificity of 95%. The diagnostic accuracy of the LAMP assay was similar to realtime and nested conventional PCR assays, but superior to the antibody-based rapid test in the early disease course. The combination of DNA- and antibody-based detection methods increased sensitivity with minimal reduction of specificity, and expanded the timeframe of adequate diagnostic coverage throughout the acute phase of scrub typhus.

    Oxides of nitrogen (NOx) [nitrogen oxide (NO) + nitrogen dioxide (NO2)] and sulfur dioxide (SO2) are removed individually in traditional air pollution control technologies. This study proposes a combined plasma scrubbing (CPS) system for simultaneous removal of SO2 and NOx. CPS consists of a dielectric barrier discharge (DBD) and wet scrubbing in series. DBD is used to generate nonthermal plasmas for converting NO to NO2. The water-soluble NO2 then can be removed by wet scrubbing accompanied with SO2 removal. In this work, CPS was tested with simulated exhausts in the laboratory and with diesel-generator exhausts in the field. Experimental results indicate that DBD is very efficient in converting NO to NO2. More than 90% removal of NO, NOx, and SO2 can be simultaneously achieved with CPS. Both sodium sulfide (Na2S) and sodium sulfite (Na2SO3) scrubbing solutions are good for NO2 and SO2 absorption. Energy efficiencies for NOx and SO2 removal are 17 and 18 g/kWh, respectively. The technical feasibility of CPS for simultaneous removal of NO, NO2, and SO2 from gas streams is successfully demonstrated in this study. However, production of carbon monoxide as a side-product (approximately 100 ppm) is found and should be considered.

  10. Impact of elevated CO2 on a Florida Scrub-oak Ecosystems

    Since May of 1996, we have conducted an experiment in Florida Scrub Oak to determine the impact of elevated atmospheric CO2 and climate change on carbon, water, and nutrient cycling in this important terrestrial ecosystem. Florida scrub oak is the name for a collective of species occupying much of the Florida peninsula. The dominant tree species are oaks and the dwarf structure of this community makes it an excellent system in which to test hypotheses regarding the potential capacity of woody ecosystems to assimilate and sequester anthropogenic carbon. Scrub oak is fire dependent with a return cycle of 10-15 years, a time which would permit an experiment to follow the entire cycle. Our site is located on Cape Canaveral at the Kennedy Space Center, Florida. After burning in 1995, we built 16 open top chambers, half of which have been fumigated with pure CO2 sufficient to raise the concentration around the plants to 350 ppm above ambient. In the intervening 10 years we have non destructively measured biomass of shoots and roots, ecosystem gas exchange using chambers and eddy flux, leaf photosynthesis and respiration, soil respiration, and relevant environmental factors such as soil water availability, temperature, light, etc. The overwhelming result from analysis of our extensive data base is that elevated CO2 has had a profound impact on this ecosystem that, overall, has resulted in increased carbon accumulation in plant shoots, roots and litter. Our measurements of net ecosystem gas exchange also indicate that the ecosystem has accumulated carbon much in excess of the increased biomass or soil carbon suggesting a substantial export of carbon through the porous, sandy soil into the water table several meters below the surface. A major discovery is the powerful interaction between the stimulation of growth, photosynthesis, and respiration by elevated CO2 and other environmental factors particularly precipitation and nitrogen. Our measurements focused attention on

    Non-surgical endodontic retreatment is the treatment of choice for endodontically treated teeth with recurrent or residual disease in the majority of cases. In some cases, surgical endodontic treatment is indicated. Successful micro-surgical endodontic treatment depends on the accuracy of diagnosis, appropriate case selection, the quality of the surgical skills, and the application of the most appropriate haemostatic agents and biomaterials. This article describes the armamentarium and technical procedures involved in performing micro-surgical endodontics to a high standard.

    Full Text Available Abstract Background Before 1986, scrub typhus was only found endemic in southern China. Because human infections typically occur in the summer, it is called "summer type". During the autumn-winter period of 1986, a new type of scrub typhus was identified in Shandong and northern Jiangsu province of northern China. This newly recognized scrub typhus was subsequently reported in many areas of northern China and was then called "autumn-winter type". However, clinical characteristics of associated cases have not been reported. Methods From 1995 to 2006, all suspected scrub typhus cases in five township hospitals of Feixian county, Shandong province were enrolled. Indirect immunofluorescent assay (IFA was used as confirmatory serodiagnosis test. Polymerase chain reaction (PCR connected with restriction fragment length polymorphism (RFLP and sequence analyses were used for genotyping of O. tsutsugamushi DNAs. Clinical symptoms and demography of confirmed cases were analyzed. Results A total of 480 scrub typhus cases were confirmed. The cases occurred every year exclusively between September and December with a peak occurrence in October. The case numbers were relatively higher in 1995, 1996, 1997, and 2000 than in other years. 57.9% of cases were in the group aged 21–50. More cases occurred in male (56% than in female (44%. The predominant occupational group of the cases was farmers (85.0%. Farm work was reported the primary exposure to infection in 67.7% of cases. Fever, rash, and eschar were observed in 100.0%, 90.4%, and 88.5% of cases, respectively. Eschars formed frequently on or around umbilicus, abdomen areas, and front and back of waist (34.1% in both genders. Normal results were observed in 88.7% (WBC counts, 84.5% (PLT counts, and 89.7% (RBC counts of cases, respectively. Observations from the five hospitals were compared and no significant differences were found. Conclusion The autumn-winter type scrub typhus in northern China occurred

    Scrub typhus is an acute infectious illness caused by Orientia tsutsugamushi. It is endemic to a part of the world known as the "tsutsugamushi triangle". Humans are accidental hosts in this zoonotic disease. About a third of patients admitted with scrub typhus have evidence of multi-organ dysfunction. Multi-organ dysfunction secondary to scrub typhus carries a high mortality rate. We report a 65-year old lady who was admitted in a Tertiary Care Center in the state of Kerala in India, with 7 day history of fever, myalgia and reduced urine output. Head to foot examination revealed the presence of an eschar on her chest. One week prior to the onset of her illness she had gone trekking through a hilly forest area. She was clinically suspected to have scrub typhus, which was later confirmed with laboratory tests. She developed multi-organ dysfunction syndrome secondary to this illness. Though there was an improvement in the multi-organ dysfunction, thrombocytopenia alone failed to improve. Bone marrow study was done which was suggestive of immune thrombocytopenia. Patient was given a course of steroids with which the thrombocytopenia improved. Failure of platelet count to normalize even after there has been a general improvement of other markers of multi-organ dysfunction in scrub typhus should prompt the clinician to consider other potential causes of thrombocytopenia. An unusual finding as this calls for further research to understand the molecular mechanisms behind such an event. Further, considering the close similarity in clinical presentation of several tropical illnesses, meticulous history taking and a detailed physical examination needs to be emphasized.

    The creation of a clinical support role for a pharmacy technician within a primary care resource center is described. In the Primary Care Resource Center (PCRC) Project, hospital-based care transition coordination hubs staffed by nurses and pharmacist teams were created in 6 independent community hospitals. At the largest site, patient volume for targeted diseases challenged the ability of the PCRC pharmacist to provide expected elements of care to targeted patients. Creation of a new pharmacy technician clinical support role was implemented as a cost-effective option to increase the pharmacist's efficiency. The pharmacist's work processes were reviewed and technical functions identified that could be assigned to a specially trained pharmacy technician under the direction of the PCRC pharmacist. Daily tasks performed by the pharmacy technician included maintenance of the patient roster and pending discharges, retrieval and documentation of pertinent laboratory and diagnostic test information from the patient's medical record, assembly of patient medication education materials, and identification of discrepancies between disparate systems' medication records. In the 6 months after establishing the PCRC pharmacy technician role, the pharmacist's completion of comprehensive medication reviews (CMRs) for target patients increased by 40.5% ( p = 0.0223), driven largely by a 42.4% ( p technician to augment pharmacist care in a PCRC team extended the reach of the pharmacist and allowed more time for the pharmacist to engage patients. Technician support enabled the pharmacist to complete more CMRs and reduced the time required for chart reviews. Copyright © 2018 by the American Society of Health-System Pharmacists, Inc.

    Internet-based cognitive behavioural therapy (iCBT) for depression is effective when guided by a clinician, less so if unguided. Would guidance from a technician be as effective as guidance from a clinician? Randomized controlled non-inferiority trial comparing three groups: Clinician-assisted vs. technician-assisted vs. delayed treatment. Community-based volunteers applied to the VirtualClinic (www.virtualclinic.org.au) research program, and 141 participants with major depressive disorder were randomized. Participants in the clinician- and technician-assisted groups received access to an iCBT program for depression comprising 6 online lessons, weekly homework assignments, and weekly supportive contact over a treatment period of 8 weeks. Participants in the clinician-assisted group also received access to a moderated online discussion forum. The main outcome measures were the Beck Depression Inventory (BDI-II) and the Patient Health QUESTIONnaire-9 Item (PHQ-9). Completion rates were high, and at post-treatment, both treatment groups reduced scores on the BDI-II (ptechnician-assisted groups respectively, and on the PHQ-9, were 1.54 and 1.60 respectively. At 4-month follow-up participants in the technician group had made further improvements and had significantly lower scores on the PHQ-9 than those in the clinician group. A total of approximately 60 minutes of clinician or technician time was required per participant during the 8-week treatment program. Both clinician- and technician-assisted treatment resulted in large effect sizes and clinically significant improvements comparable to those associated with face-to-face treatment, while a delayed treatment control group did not improve. These results provide support for large scale trials to determine the clinical effectiveness and acceptability of technician-assisted iCBT programs for depression. This form of treatment has potential to increase the capacity of existing mental health services. Australian New

    The workshop was held to exchange information on existing facilities and programmes in Asia and the Pacific for training nuclear laboratory technicians, to identify future training needs and to assess the need for IAEA's involvement in this field. As the participants outlined the requirements for nuclear laboratory technician training and the facilities available in their respective countries, it became evident that, in addition to the training of radioisotope laboratory technicians, they also wished to review the need for technician training for the operation of nuclear power plants and industrial application of atomic energy. The terms of reference of the workshop were extended accordingly. The opening address by Chang Suk Lee, the Korean Vice Minister of Science and Technology, noted the valuable contribution to quality control and other industrial uses that nuclear techniques have made in his country. He also reviewed the application of nuclear techniques in Korean agriculture and medicine. The participants explored various forms of co-operation that could be established between countries of the region. Exchange programmes, not only for students but also for expert teachers, and the exchange or loan of equipment were suggested. It was felt that some generalized training courses could be organized on a regional basis, and two countries advocated the setting up of a regional training centre. One suggestion was to arrange regional training courses in special fields that would move from one country to another. The need was felt for periodic regional meetings on training methods, course content and other questions relating to training of laboratory technicians. The IAEA was requested to act as a clearinghouse for information on available training facilities in the region and to advise on the curricula for technician training courses. The Agency was also asked to organize short courses for the training of instructors of technicians in the various fields of atomic

It's purpose is providing professional training of students in the area of diagnostic imaging, nuclear medicine and radiotherapy. Practical training is based on the scientific and theoretical knowledge and skills and is organized in pedagogic environment, adequate to regularities for a gradual formation of practical skills and habits. The practical training and pre-graduation internship are performed in 1895 from total of 3810 hours, which represents about fifty percent of all training of X-ray technicians. Students are in groups of 2-4 students. Practical training is organized, accomplished and monitored by the teacher training practice with the help of a mentor in the clinical base. Purpose: To present the tasks of practical training of students - X-ray technicians and the requirements for the personal characteristics and activity of mentors. Materials and methods: Documentary method has been used. Literature and normative documents related to the practical training of students in 'X-ray technician' of Medical Colleges have been studied. The job descriptions of senior clinical X-ray technicians have been examined carefully. Results: By analyzing literature sources, we have structured the tasks of practical training and pre-graduation internship of students - X-ray technicians, also we have described the requirements for personal qualities of mentors and systematize the activities they perform. Conclusion: Practical training plays an important role in adaptation of young X-ray technicians to the conditions of medical work, improving their skills and habits, and to the development of specific practical skills for being able to respond to emergency conditions and to solve complicated practical situations. The mentor is the supervisor and the controller of interns who helps this happen through his own example, qualities and attitudes towards

    Pharmacy technicians are a vital part of the health care workforce. Little is known about perceptions of their own work environment that would engender more effective recruitment, retention, and management strategies by pharmacists and employers. The purpose of this study was to gain a greater understanding of certified pharmacy technician worklife. Specific objectives included the identification of themes of worklife phenomena to assist with the development of appropriate responses by other pharmacy stakeholders and to ascertain the contribution of various factors engendering or discouraging career commitment of pharmacy technicians. Semi-structured in-depth interviews were carried out with a convenience sample of pharmacy technicians in one U.S. state, who varied by their work settings and level of experience. The interview guide and corresponding participant responses were framed from around an organizational cultural basis rooted in organizational behavior theory. Notes from the interviews were analyzed thematically using directed content analysis. Four primary themes emerged, including: career impetus, job responsibilities, quality of work life, and equitable partnership. The data revealed pharmacy technicians' need for self-actualization and recognition of the value they bring to the organization. The participants identified primary responsibilities that contribute to their sense of worth and those that if not managed adequately potentially detract from their well-being and effectiveness. Findings in regard to rate of pay corroborate previous work on wages as both an intrinsic and extrinsic motivator. Pharmacy technicians seek equity among each other (their peers) and in a mutually beneficial relationship with their employing organization. This study provides the impetus for interventions and further study that should serve to enhance pharmacy technician effectiveness, quality of work life, and longevity in an emerging profession.

    Background Laiwu District is recognized as a hyper-endemic region for scrub typhus in Shandong Province, but the seriousness of this problem has been neglected in public health circles. Methodology/Principal Findings A disability-adjusted life years (DALYs) approach was adopted to measure the burden of scrub typhus in Laiwu, China during the period 2006 to 2012. A multiple seasonal autoregressive integrated moving average model (SARIMA) was used to identify the most suitable forecasting model for scrub typhus in Laiwu. Results showed that the disease burden of scrub typhus is increasing yearly in Laiwu, and which is higher in females than males. For both females and males, DALY rates were highest for the 60–69 age group. Of all the SARIMA models tested, the SARIMA(2,1,0)(0,1,0)12 model was the best fit for scrub typhus cases in Laiwu. Human infections occurred mainly in autumn with peaks in October. Conclusions/Significance Females, especially those of 60 to 69 years of age, were at highest risk of developing scrub typhus in Laiwu, China. The SARIMA (2,1,0)(0,1,0)12 model was the best fit forecasting model for scrub typhus in Laiwu, China. These data are useful for developing public health education and intervention programs to reduce disease. PMID:25569248

    Full Text Available The present paper proposes a CFD model to study sulphur dioxide (SO2 absorption in seawater. The focus is on the treatment of marine diesel engine exhaust gas. Both seawater and distilled water were compared to analyze the effect of seawater alkalinity. The results indicate that seawater is more appropriate than distilled water due to its alkalinity, obtaining almost 100% cleaning efficiency for the conditions analyzed. This SO2 reduction meets the limits of SOx emission control areas (SECA when operating on heavy fuel oil. These numerical simulations were satisfactory validated with experimental tests. Such data are essential in designing seawater scrubbers and judging the operating cost of seawater scrubbing compared to alternative fuels.

    If genetic variation is often positively correlated with population sizes and the presence of nearby populations and suitable habitats, landscape proxies could inform conservation decisions without genetic analyses. For six Florida scrub endemic plants (Dicerandra frutescens, Eryngium cuneifolium, Hypericum cumulicola, Liatris ohlingerae, Nolina brittoniana, and Warea carteri), we relate two measures of genetic variation, expected heterozygosity and alleles per polymorphic locus (APL), to population size and landscape variables. Presettlement areas were estimated based on soil preferences and GIS soils maps. Four species showed no genetic patterns related to population or landscape factors. The other two species showed significant but inconsistent patterns. For Liatris ohlingerae, APL was negatively related to population density and weakly, positively related to remaining presettlement habitat within 32 km. For Nolina brittoniana, APL increased with population size. The rather weak effects of population area/size and both past and current landscape structures suggest that genetic variation needs to be directly measured and not inferred for conservation planning.

    This paper reports on the technical and institutional feasibility of incinerating hydrogen sulfide (H2S) contained in geothermal noncondensable gases, and the use of geothermal brine for sulfur dioxide scrubbing and absorption as an Air Emissions Control System (AECS), for geothermal power plant, that have been documented through engineering analysis in the Phase I grant study funded through the California Department of Health Services (DOHS), Hazardous Materials Reduction Grant Program and hosted by California Energy Company (CECI). Grant funding for Phase II now has been approved to proceed with the project through the pilot plant design phase. This innovative AECS does not necessitate the use of hazardous materials or produce hazardous wastes. Cost savings were documented compared to injection pump operation or conventional AECS without the use of hazardous materials. The phase II project is to design, improve, research and develop a source reduction demonstration pilot plant geothermal noncondensable H2S incineration AECS

    Full Text Available Two wild groups of Callithrix penicillata, the Black Pincelled Marmoset, were observed from January to September 1998, in two areas, one an area of dense scrub savanna vegetation (cerrado and the other, a semidecidual woodland (cerradão, both within the boundaries of the Ecological Reserve of IBGE (Brazilian Institute of Geography and Statistics, in an environmentally protected area, the APA (Portuguese abbreviation for "environmental protected area" Gama/Cabeça-de-Veado, Brasília, DF. The behavioral data collected during the rainy (January 15 to April 15 and dry season (June 1 to September 15 were compared. Because of the proximity to the Reserve facilities, the group from the dense scrub savanna vegetation (CD was submitted to antropic impacts different from the group in the semidecidual woodland (CE, which was using as territory an area that had been suffering from man-made fires every two years as part of a long-term experimental project on fire impacts. The behavioral data was quantified by instantaneous cross-section ("scan sampling" every ten minutes with records of locomotion, rest, foraging for insects, use of exudate, and feeding. During the whole year, the greatest percentage of time spent by CE and CD was in foraging for insects, with 44% and 39%, respectively. It was evident when comparing the data for the two seasons that, for both groups, foraging for insects was more intense during the dry season, possibly to complement the shortage of food, and locomotion increased during the rainy season. The greater the availability and distribution of fruit in the areas, the greater the locomotion of the groups to obtain these resources. None of the other behavioral patterns, including the use of exudates, presented significant differences between the two seasons. Both groups foraged more frequently during the dry season and locomoted more during the rainy one.

    Background. Swine-origin influenza A (H1N1) virus (S-OIV) infection and scrub typhus, also known as tsutsugamushi disease can manifest as acute respiratory illnesses, particularly during the late fall or early winter, with similar radiographic findings, such as a predominance of ground-glass opacity (GGO). Purpose. To differentiate S-OIV infection from scrub typhus using high-resolution computed tomography (HRCT). Material and Methods. We retrospectively reviewed the HRCT findings of 14 patients with S-OIV infection and 10 patients with scrub typhus. We assessed the location, cross-sectional distribution, and the presence of a peribronchovascular distribution of GGO and consolidations on HRCT. We also assessed the presence of interlobular septal thickening, bronchial wall thickening, pneumothorax, pneumomediastinum, pleural effusion, and mediastinal or axillary lymph node enlargement. Results. Scrub typhus was more common than S-OIV in elderly patients (P < 0.001). The monthly incidences of S-OIV and scrub typhus infection reached a peak between October and November. About 86% of S-OIV patients and 80% of scrub typhus patients presented with GGO. About 67% of the GGO lesions in S-OIV had a peribronchovascular distribution, but this was absent in scrub typhus (P = 0.005). Consolidation (93% vs. 10%, P < 0.001) and bronchial wall thickening (43% vs. 0%, P = 0.024) were more frequent in S-OIV infection than scrub typhus. Interlobular septal thickening (90% vs. 36%, P = 0.013) and axillary lymphadenopathy (90% vs. 0%, P < 0.001) were more common in scrub typhus than S-OIV infection. Conclusion. There was considerable overlap in HRCT findings between S-OIV infection and scrub typhus. However, S-OIV showed a distinctive peribronchovascular distribution of GGO lesions. Consolidation and bronchial wall thickening were seen more frequently in S-OIV infection, whereas interlobular septal thickening and axillary lymphadenopathy were more common in scrub typhus. Thus, CT could

    Norcross, Robert

    Aircraft maintenance technician decision-making and actions have resulted in aircraft system errors causing aircraft incidents and accidents. Aircraft accident investigators and researchers examined the factors that influence aircraft maintenance technician errors and categorized the types of errors in an attempt to prevent similar occurrences. New aircraft technology introduced to improve aviation safety and efficiency incur failures that have no information contained in the aircraft maintenance manuals. According to the Federal Aviation Administration, aircraft maintenance technicians must use only approved aircraft maintenance documents to repair, modify, and service aircraft. This qualitative research used a grounded theory approach to explore the decision-making processes and actions taken by aircraft maintenance technicians when confronted with an aircraft problem not contained in the aircraft maintenance manuals. The target population for the research was Federal Aviation Administration licensed aircraft and power plant mechanics from across the United States. Nonprobability purposeful sampling was used to obtain aircraft maintenance technicians with the experience sought in the study problem. The sample population recruitment yielded 19 participants for eight focus group sessions to obtain opinions, perceptions, and experiences related to the study problem. All data collected was entered into the Atlas ti qualitative analysis software. The emergence of Aircraft Maintenance Technician decision-making themes regarding Aircraft Maintenance Manual content, Aircraft Maintenance Technician experience, and legal implications of not following Aircraft Maintenance Manuals surfaced. Conclusions from this study suggest Aircraft Maintenance Technician decision-making were influenced by experience, gaps in the Aircraft Maintenance Manuals, reliance on others, realizing the impact of decisions concerning aircraft airworthiness, management pressures, and legal concerns

    To discuss the policy of pharmacy technician-to-pharmacist ratios by comparing Florida as an example of legislative-led authority versus Tennessee as an example of board of pharmacy-led ruling. Over the past 2 years, the Florida legislature has debated the issue of pharmacy staffing ratios, initially leaving the Florida Board of Pharmacy with little authority to advocate for and enact safe technician staffing ratios. Anticipating this situation, the Tennessee Board of Pharmacy created rules to meet pharmacy staffing needs while protecting the authority of the pharmacist-in-charge and promoting patient safety. Before enacting rules, members of the board toured the state and talked about proposed rule changes with pharmacists. The final rule sets the pharmacy technician-to-pharmacist ratio at 2:1 but permits a 4:1 ratio based on public safety considerations and availability of at least two Certified Pharmacy Technicians. Pharmacists and leaders within the profession should conduct further research on appropriate and safe ratios of pharmacy technicians to pharmacists, with a focus on safety and quality of care.

    Four transcranial magnetic stimulation (TMS) devices are currently approved for use in treatment-resistant depression. The authors present the first data-driven study examining the patient- and technician-experience using three of these distinct devices. A retrospective survey design with both patient and technician arms was utilized. The study population included patients who received TMS for treatment-resistant depression at the Berenson Allen Center for Noninvasive Brain Stimulation for the first time between 2013 and 2016 and technicians who worked in the program from 2009 to 2017. Statistical analysis included t tests and analyses of variance to assess differences between and across the multiple groups, respectively. Patients treated with the NeuroStar device reported greater confidence that the treatment was being performed correctly compared with those treated with the Magstim device. Conversely, with regard to tolerability, patients treated with the Magstim device reported less pain in the last week and less pain on average compared with those treated with the NeuroStar device. On average, technicians reported feeling that both the Magstim and NeuroStar devices were significantly easier to use than the Brainsway Deep TMS H-Coil device. Additionally, they found the former two devices to be more reliable and better tolerated. Furthermore, the technicians reported greater confidence in the Magstim and NeuroStar devices compared with the Brainsway Deep TMS H-Coil device and indicated that they would be more likely to recommend the two former devices to other treatment centers.

    The aim of this study was to identify the effects of long term exposure of X-ray on diagnostic technicians which they work at Kirkuk hospitals through examining some hematological parameters which are white blood cells (WBC), Neutrophils, Lymphocyte, Monocyte, Eosinophil, Basophil, Reactive Lymphocyte, red blood cells (RBC), hemoglobin (Hb), hematocrit (HCT), Mean Cell Volume (MCV), Mean Corpuscular Hemoglobin (MCH), Mean Cell Hemoglobin Concentration (MCHC), Red Cell Distribution Width (RDW), Platelet (PLT). The study included 54 male diagnostic technicians and 54 male healthy controls match with the first group to show any alteration of the hematological parameters. The diagnostic technicians divided into two groups depending on their work experience and hours working per day. The statistical analysis was performed using (Graph-pad) program. Our results showed that the Complete blood cells count (CBC) parameters (Neutrophil, Monocytes, Basophile, MCV, RDW and PLT) significantly (Pgroups of the diagnostic technicians compared with their controls. We concluded that chronic exposure of X-ray can significantly alter some hematological parameters and the number of hours working per day has observable effects on the some hematological parameters. We recommended training and courses about hazard of ionizing radiation should be organized for enhance the healthcare quality of the technicians and to improve their knowledge about benefit of radiation protection tools to protect themselves from any overexposure during the daily life.

    Full Text Available The aim of this study was to evaluate potential DNA damage and cytotoxicity in pathology laboratory technicians exposed to organic solvents, mainly xylene. Peripheral blood and buccal cells samples were collected from 18 technicians occupationally exposed to organic solvents and 11 non-exposed individuals. The technicians were sampled at two moments: Monday and Friday. DNA damage and cytotoxicity were evaluated using the Comet Assay and the Buccal Micronucleus Cytome assay. Fifteen subjects (83.5% of the exposed group to solvents complained about some symptom probably related to contact with vapours of organic solvents. DNA damage in the exposed group to solvents was nearly 2-fold higher on Friday than on Monday, and in both moments the individuals of this group showed higher levels of DNA damage in relation to controls. No statistical difference was detected in buccal cell micronucleus frequency between the laboratory technicians and the control group. However, in the analysis performed on Friday, technicians presented higher frequency (about 3-fold of karyolytic and apoptotic-like cells (karyorrhectic and pyknotic in relation to control group. Considering the damage frequency and the working time, a positive correlation was found in the exposed group to solvents (r=0.468; p=0.05. The results suggest that pathology laboratory workers inappropriately exposed to organic solvents have increased levels of DNA damage.

    Lower back pain (LBP) is the most common complaint worldwide and the leading cause of disability in the workplace. In Colombia there are no epidemiological data on low back pain in aviation. This study aimed to characterize lower back pain in pilots and maintenance technicians in a Colombian commercial airline. Information was collected from the total population in a Colombian commercial airline in Bogota during the period from 2011 to 2013 using a voluntary survey which requested demographics, occupational (LEST survey) factors, back pain, and chronic pain (chronic pain grade scale). The prevalence rate of LBP in pilot respondents was 71% and the factors associated previously have belonged to the military forces: occupational exposure to physical load and work time. Chronic low back pain was at a prevalence of 49%. The prevalence of LBP in maintenance technicians was 65%. Associated factors were again similar to military forces and included mental workload. Chronic pain had a prevalence of 65%. Factors associated with chronic low back pain were the technicians' time in office and physical load. The prevalence of lower back pain in pilots is similar to that presented in the airline world population. In the case of maintenance technicians, the prevalence was higher than those found in other similar groups, but very similar to prevalences presented in different business industries, including the transport sector.

    To quantify consistency of endothelial cell density (ECD) measurements among technicians in a single US eye bank operating under typical operating conditions. In this retrospective analysis of 51 microscopy technicians using a semiautomated counting method on 35,067 eyes from July 2007 to May 2015, technician- and date-related marginal ECD effects were calculated using linear regression models. ECD variance was correlated with the number of specular microscopy technicians. Technician mean ECDs ranged from 2386 ± 431 to 3005 ± 560 cells/mm. Nine technicians had statistically and clinically significant marginal effects. Annual mean ECDs adjusted for changes in technicians ranged from 2422 ± 433 to 2644 ± 430 cells/mm. The period of 2007 to 2009 had statistically and clinically significant marginal effects. There was a nonstatistically significant association between the number of technicians and ECD standard deviation. There was significant ECD variability associated with specular microscopy technicians and with the date of measurement. We recommend that eye banks collect data related to laboratory factors that have been shown to influence ECD variability.

    To determine occupational association with metabolic syndrome among auto technicians and school teachers. One hundred and sixty six subjects were selected for this study. Clinical data was obtained while laboratory investigations including plasma glucose and lipid profile were performed. Statistical analysis was done with SPSS 20.0. Pauto technicians. Mean serum triglycerides was significantly higher among auto-technicians compared to school teachers in this study. The prevalence of some conventional cardiovascular risk factors was significantly higher among auto-technicians compared to school teachers: Impaired blood glucose (9.6% vs. 1.2%, pauto-technicians. Based on the WHO and the Harmonized criteria, metabolic syndrome was more frequent among auto-technicians compared to school teachers. (8.4% vs. 1.2% and 19.3% vs. 7.2% respectively, pauto technicians despite their high level of physical activity, exertion and education compared to teachers. This may be related to the increased occupational exposure to organic and inorganic materials from dust particles, oil and oil related matter and particulate matter among auto technicians. Prompt definitive evaluation of this concept and appropriate health education to encourage safety mechanism can reduce this burden of metabolic syndrome among auto technicians in Nigeria.

    Basic surgical skills modules in medical education are effective in teaching skills and increasing confidence among students approaching surgery. However, these modules are not delivered universally and their effect on the professional development of graduates has not been established. We aimed to assess the impact of a 10-week basic surgical skills module on attitudes and technical skills of first year medical students compared to interns. Eighteen students participated and were assessed using a 4-part questionnaire. Technical skills were assessed by observing students perform a basic interrupted suture, using the objective structured assessment of technical skills (OSATS) tool. Fourteen interns were recruited. Students were more confident in surgical scrubbing (mean score 4.0 vs. 2.86, p = 0.001), and performing a basic suture (4.05 vs. 1.93, p = 0.000), more enthusiastic about assisting with an operation (4.5 vs. 3.0, p = 0.001) and more likely to consider a career in surgery (4.16 vs. 2.28, p = 0.000). Technical skills were greater in the student group (mean score 30.8 vs. 19.6, p = 0.001). Five interns had taken part in surgical skills modules as undergraduates. Their technical skills were significantly higher compared to interns who had not (n = 9) (28.8 vs. 14.5, p = 0.006), and they were more likely to consider a career in surgery (3.6 vs. 1.5, p = 0.036). The introduction of surgical skills teaching to the undergraduate medical curriculum has a positive impact on students' attitudes towards surgery and accelerates basic technical skills development. Consideration should be given to development of a standardised undergraduate core curriculum in basic surgical skills teaching.

    Highlights: • Insights into power requirements of biomethane production from biogas are provided. • Process model is constructed, validated and simulated. • High-pressure and low-pressure plant operation in different configurations is compared. - Abstract: Biogas upgrading by water scrubbing followed by biomethane compression is an environmentally benign process. It may be achieved using various plant configurations characterised by various power requirements with associated effects on biomethane sustainability. Therefore, the current study has been undertaken to systematically investigate the power requirements of a range of water scrubbing options. Two groups of water scrubbing are analysed: (1) high pressure water scrubbing (HPWS) and (2) near-atmospheric pressure water scrubbing (NAPWS). A water scrubbing plant model is constructed, experimentally validated and simulated for seven upgrading plant configurations. Simulation results show that the power requirement of biogas upgrading in HPWS plants is mainly associated with biogas compression. In contrast, in NAPWS plants the main power is required for water pumping. In both plants the compression of the biomethane from atmosphereic pressure to 20 MPa also contributes remarkably. It is observed that the lowest specific power requirement can be obtained for a NAPWS plant without water regeneration (0.24 kW h/Nm"3 raw biogas) but this plant requires cheap water supply, e.g. outlet water from a sewage treatment plant or river. The second is HPWS without flash (0.29 kW h/Nm"3 raw biogas). All other HPWS with flash and NAPWS with water regeneration plants have specific power requirements between 0.30 and 0.33 kW h/Nm"3 raw biogas. Biogas compression without upgrading requires about 0.29 kW h/Nm"3 raw biogas. The thermodynamic efficiency of biogas upgrading is between 2.2% and 9.8% depending on the plant configuration while biomethane compression efficiency is higher, about 55%. This result implies that the

    Most patient education involves passive learning. To improve patient education regarding surgery, an active learning workshop-based teaching method is proposed. The objective of this study was to assess level of patient surgical knowledge, achievement of workshop learning objectives, patient apprehension about future surgery, and participant workshop satisfaction after completing a surgical training workshop. A four-station workshop (surgical scrub, surgical suture, laparoscopic surgery, and robotic surgery) was developed to teach four important components of the surgical process. Healthy, surgery-naive adolescents were enrolled to attend this 1-h workshop-based training program. Training received by participants was technically and procedurally identical to training received by actual surgeons. Pre- and post-workshop questionnaires were used to assess learning outcomes. There were 1312 participants, with a mean age 15.9 ± 1.1 years and a gender breakdown of 303 males and 1009 females. For surgical knowledge, mean pre-workshop and post-workshop scores were 6.1 ± 1.5 and 7.5 ± 1.5 (out of 10 points), respectively (p education is an effective way to improve understanding of surgery-related processes. This teaching method may also decrease apprehension that patients or potential patients harbor regarding a future surgical procedure.
