    Aims: To determine the indications for penetrating keratoplasty (PK) at the Corneoplastic Unit and Eye Bank, UK, a tertiary referral centre, over a 10 year period. Methods: Records of all patients who underwent PK at our institution between 1990 and 1999 were reviewed retrospectively. Of the 1096 procedures performed in this period, 784 records were available for evaluation (72%). Results: Regrafting was the most common indication, accounting for 40.9% of all cases. Keratoconus was the second most common indication (15%), followed by Fuchs’ endothelial dystrophy (9.3%), pseudophakic bullous keratopathy (7.6%), and viral keratitis (5.9%), which included both herpes simplex and herpes zoster and showed a statistically significant decreasing trend using regression analysis (p<0.005). Among the regraft subgroup, viral keratitis accounted for 21.2% as the underlying primary diagnosis. The most common cause for graft failure in the regraft subgroup was endothelial failure (41.8%). Conclusion: Regrafting is the leading indication for PK; viral disease—although declining—is the leading primary diagnosis. PMID:15258012

    Planetary period oscillations (PPOs) with periods close to Saturn's rotational period are ubiquitous throughout Saturn's magnetospheric system. Here we review the observational studies of PPOs determined from magnetospheric magnetic field data throughout the Cassini mission to date. As first shown using radio data, two oscillatory systems are present, one associated with the northern polar region and the other with the southern. We show that within the northern (southern) open-field polar region only the northern (southern) PPO oscillations are detected. However, within the equatorial 'core' region of Saturn's magnetosphere (dipole L ≤ 12), the two oscillations are superposed and interfere. The PPO periods are shown to lie in the range ~10.6 to 10.8 h, are persistently shorter north than south to date, and undergo a strong seasonal cycle together with the oscillation amplitudes. We discuss these observations in relation to theoretical models that have been proposed to explain them, and emphasize the importance of continued measurement of their properties during the Cassini solstice mission.

    Background: Kidney transplantation is a preferred treatment for many patients with end-stage renal disease (ESRD) and is far more profitable than hemodialysis. Analyzing renal transplantation data can help to evaluate the effectiveness of transplantation interventions. The aim of this study was to determine the organ survival rate after kidney transplantation during a period of 10 years (March 2001-March 2011) among transplanted patients in Arak, Markazi Province, Iran. Materials and Methods: In this historical cohort study, all recipients of kidney transplantation from Arak, Markazi Province, Iran who had medical records in Valiasr Hospital and “charity for kidney patients” of Arak, Markazi Province, Iran during a period of 10 years from March 2001 to March 2011 were included. Data collected by using checklists were completed from patients’ hospital records. Kaplan-Meier method was used to determine the graft cumulative survival rate, log-rank test to compare survival curves in subgroups, and Cox regression model to define the hazard ratio and for ruling out the intervening factors. Statistical analysis was conducted by Statistical Package for the Social Sciences (SPSS) 20 and Stata 11. Results: Mean duration of follow-up was 55.43 ± 42.02 months. By using the Kaplan-Meier method, the cumulative probability of graft survival at 1, 3, 5, 7, and 10 years was 99.1, 97.7, 94.3, 85.7, and 62.1%, respectively. The number of dialysis by controlling the effect of other variables had a significant association with the risk of graft failure [hazard ratios and 95% confidence interval (CI): 1.47 (1.02-2.13)]. Conclusion: This study showed that the graft survival rate was satisfactory in this community and was similar to the results of single-center studies in the world. Dialysis time after transplantation was a significant predictor of survival in the recipients of kidney transplantation that should be considered. PMID:26941807

    Sex differences in declarative memory and visuospatial ability are robust in cross-sectional studies. The present longitudinal study examined whether sex differences in cognition were present over a 10-year period, and whether age modified the magnitude of sex differences. Tests assessing episodic and semantic memory, and visuospatial ability were administered to 625 nondemented adults (initially aged 35-80 years), participating in the population-based Betula study at two follow-up occasions. There was stability of sex differences across five age groups and over a 10-year period. Women performed at a higher level than men on episodic recall, face and verbal recognition, and semantic fluency, whereas men performed better than women on a task-assessing, visuospatial ability. Sex differences in cognitive functions are stable over a 10-year period and from 35 to 90 years of age.

    The study evaluated the changes in the prevalence of Helicobacter pylori strains with primary resistance to antibiotics during the last 10 years in Lithuania. H. pylori susceptibilities to antibiotics were tested in 89 patients in 1998, in 81 patients in 2001 and in 90 patients in 2007/2008. Susceptibility to metronidazole, clarithromycin, amoxicillin and tetracycline was tested using E-test or agar dilution method. Susceptibility to ciprofloxacin was only tested in 2007/2008. Data about utilization of all authorized and available on market macrolides and clindamycin in Lithuania during 2003-2007 were evaluated using WHO ATC/DDD methodology. A total of 260 H. pylori strains cultured from untreated adult patients were investigated. Primary resistance rates (1998, 2001 and 2007/2008) for metronidazole were 24.7%, 33.3%, and 35.6%, for clarithromycin 1.1%, 3.7%, and 3.3% and for tetracycline 0%, 2.5% and 0% respectively. No cases of amoxicillin resistance have been detected. The resistance rate for ciprofloxacin was 5.6% in 2007/2008. Data of total macrolides and clarithromycin utilization in Lithuania revealed that despite an increase of consumption of these drugs in Lithuania during 2003-2007 in 1.5 times, the total macrolide consumption remains one of the lowest in Europe. We have not observed any significant changes in the susceptibility of H. pylori to the most widely used antibiotics during the recent 10-year period. The low resistance rate to clarithromycin might be related to the policy to avoid use of macrolides as first-line treatment for pulmonary and other infections.

    We report the results of a retrospective epidemiologic study on neuroblastoma in Brittany, a region of France characterized by an homogeneous sedentary population living on a granitic ground. During a period of 10 years (1980-1989), 48 cases of neuroblastoma were observed, which gives an incidence of 7.92 cases per million of children under 15 years. There were 25 boys and 23 girls and 20 infants under 1 year (41%). The localisation was abdominal in 39 cases (81%). Among the 28 children older than 1 year, 25 (89%) had stage III and stage IV neuroblastomas, half of them with metastases. We conclude that the incidence and the clinical presentation of neuroblastoma in Brittany are similar to those reported in other countries.

    We examined the relation of hostility, anger and depression to 10-year changes in the third (C3) and fourth (C4) complement in 313, apparently healthy male participants enrolled in the Air Force Health Study (AFHS), a 20-year study designed to evaluate the health consequences of dioxin exposure. Hostility, depression and anger were assessed using subscales from the Minnesota Multiphasic Personality Inventory (MMPI), which was administered in 1985. Given the high intercorrelations among these psychological scales, we used a principal component analysis to generate a composite score representing the linear combination of the hostility, anger and depression scales. The dependent variables, C3 and C4 levels, were determined from samples collected in 1992, 1997 and 2002. Regression analyses controlling for age, race, alcohol use, body mass index and cigarette use as well as onset of disease and use of lipid lowering and blood pressure medications during follow-up revealed a significant time X composite score interaction for C3 complement (p < .0003), but not C4. Post-hoc analyses revealed that high composite scores were associated with larger 10-year increases in C3. These observations suggest that men who are hostile and are prone to experience frequent and intense feelings of anger and depression show activation of the complement system, and specifically increases in C3, that may contribute to the development of coronary heart disease.

    A fungal ball consists of a dense conglomerate of fungal hyphae growing at the surface of the sinus mucosa without tissue infiltration. The maxillary sinus is by far the most commonly involved paranasal sinus cavity followed by the sphenoid sinus. The present study is a retrospective study of 25 consecutive cases treated during the last 10 years in the two hospitals be- longing to the Catholic University of Louvain (CHU Mont-Godinne and UCL Saint Luc). We report the symptomatology, the imaging and discuss the different surgical managements. We conclude that the clinician must have a high index of suspicion when dealing with a unilateral rhinosinusitis persisting despite a maximal and well conducted medical treatment. This is particularly so in elderly women when associated with facial pain and post nasal drip, particularly when the computed tomography shows an unilateral opacity of the sphenoid sinus with or without a sclerosis or an erosion of the bony walls, a polyp in the sphenoethmoidal recess or a hyperdensity mimicking a foreign body. An endonasal endoscopic sphenoidotomy is the treatment of choice in most cases, allowing good ventilation of the sinus and radical removal of all the fungal concretion. A biopsy of the sinus mucosa adjacent to fungal elements is of upmost important to confirm the non- invasiveness of the fungi within the tissue. Antifungal medication is not required in uncomplicated forms. All host factors producing some degree of immunosuppression must be corrected when present and must alert the clinician to rule out any forms of invasive disease.

    Objective. There is a paucity of research on substance use disorders (SUDs) in the elderly psychiatric population. This study examines SUDs in a geriatric psychiatry inpatient service over a 10-year period. Methods. Data from 1788 elderly psychiatric inpatients from a ten-year period was collected. Variables collected included psychiatric diagnoses, SUD, number of psychiatric admissions, and length of stay. Those with and without a SUD were compared using Chi-Square or Student's t-test as appropriate using SPSS. Results. 11.7% (N = 210) of patients had a SUD, and the most common substance was alcohol at 73.3% (N = 154) or 8.6% of all admissions. Other SUDs were sedative-hypnotics (11%), opiate (2.9%), cannabis (1%), tobacco (1.4%), and unspecified SUD (38.6%). SUD patients were significantly younger, divorced, male, and less frequently readmitted and had shorter lengths of stay. The most common comorbid diagnoses were major depression (26.1%), bipolar disorder (10.5%), and dementia (17.1%). Conclusions. Over 10% of psychogeriatric admissions were associated with a SUD, with alcohol being the most common. Considering the difficulties in diagnosing SUD in this population and the retrospective study design, the true prevalence in elderly psychiatric inpatients is likely higher. This study adds to sparse literature on SUD in elderly psychiatric patients. PMID:27840765

    We review and discuss the results of treatments for complications of cholesteatomatous chronic otitis media (CCOM) in a tertiary health care center. In a retrospective study, the medical records of patients with complications of CCOM who had undergone surgical treatment at the ENT Clinic of the University Clinical Center of Kosovo for the period 1994-2004 were reviewed. From a total of 1,803 patients suffering from CCOM, in 91 patients, 55 (60.4%) men and 36 (39.6) women, one or two complications are recorded. The mean age of the subjects was 30 years, and the age range was from 1 to 76 years. Extracranial (EC) complications were observed in 52 cases (57.1%), and intracranial (IC) complications were seen in 29 patients (31.9%). Twelve patients (11%) had multiple complications. For the EC cases, we found that subperiostal mastoidal abscess occurred in 26% of the all patients, facial nerve palsy was seen in 16.48% and labyrinthine fistula occurred in 10%. For the IC cases, meningitis (19.7%) and perisinusal abscess (15.3%) were the most common complications. The most often isolated pathogen from ear swabs was Proteus mirabilis in 33.3% of cases. The most frequent radiological diagnostic procedures were mastoid tip X-rays, which were performed in 77% of the patients, and computed tomography in 24%; magnetic resonance imaging was not performed on any of the patients during the study period. Patients with EC complications were treated in the ENT Clinic, whereas patients with IC complications, after otologic surgical procedures, were transferred to the Neurosurgery Clinic or to the Clinic for Infectious Diseases. In this series, three patients (3.3%) died as a result of complications, while the remaining 96.7% survived. Complications of COM with cholesteatoma can represent life-threatening conditions, and close cooperation between otosurgeons, neurosurgeons and infectious disease specialists is mandatory.

    Objective This study aimed at describing the profiles of Brazilian and international studies published in orthodontic journals. Methods The sample comprised 635 articles selected from two scientific journals, i.e., Dental Press Journal of Orthodontics and American Journal of Orthodontics and Dentofacial Orthopedics, which were analyzed at three different intervals over a 10-year period (1999 - 2004 - 2009). Articles were described in terms of knowledge domain, study design, and country of origin (or state of origin for Brazilian papers). Results The most frequent study designs adopted in international studies were cohort (23.9%) and cross-sectional (21.7%) designs. Among Brazilian papers, cross-sectional studies (28.9%) and literature reviews (24.6%) showed greater frequency. The topics most often investigated were dental materials (17%) and treatment devices (12.4%) in international articles, with the latter topic being addressed by 16% of the Brazilian publications, followed by malocclusion, with 12.6%. In all cases, the most frequent countries of origin coincided with the countries of origin of each journal. Conclusions The majority of the studies analyzed featured a low level of scientific evidence. Moreover, the findings showed that journals tend to publish studies produced in their own country of origin, and that there are marked discrepancies in the number of papers published by different Brazilian states.

  15. Reconstruction of mandibular defects - clinical retrospective research over a 10-year period -

    PubMed Central

    2011-01-01

    Backround Functional and cosmetic defects in the maxillofacial region are caused by various ailments and these defects are addressed according to their need. Simplicity of procedure, intact facial function and esthetic outcome with the least possible donor site morbidity are the minimum requirements of a good reconstruction. Oro-mandibular reconstruction, although a challenge for the head and neck reconstructive surgeon, is now reliable and highly successful with excellent long-term functional and aesthetic outcomes with the use of autogenous bone grafts. Reconstruction of trauma- or mandibular oncologic defects with bony free flaps is considered the gold standard. However the the optimal reconstruction of mandibular defects is still controversial in regards to reconstructive options which include the donor site selection and the timing of surgery. The purpose of this study was to determine the outcome of different osseous reconstruction options using autogenous bone grafts for mandibular reconstructions. Methods This study was carried out on 178 patients with mandibular bone defects. They were reconstructed with autogenous bone grafts from different donor sites. At post operative visits they were evaluated for functional and cosmetic results. Results The success rate found in this study was around 90%. Only 7.6% of the cases showed poor results regarding facial contours and mouth opening. All other patients were satisfied with their cosmesis and mouth opening at the recipient sites was in the normal range during last follow-up visits. Donor sites were primarily closed in all cases and there was no hypertrophic scar. Conclusion Based on this study, autogenous bone grafts are a reliable treatment modality for the reconstruction of mandibular bone defects with predictable aesthetic and functional outcomes. As the free vascularized fibular flap has the least resorption and failure rate, it should be the first choice for most cases of mandiblular reconstruction. PMID

    Background Staphylococci can cause wound infections and community- and nosocomial-acquired pneumonia, among a range of illnesses. Staphylococcus aureus and methicillin-resistant S. aureus (MRSA) have been rapidly increasing as a cause of infections worldwide in recent decades. Numerous reports indicate that S. aureus and MRSA are becoming resistant to many antibiotics, which makes them very dangerous. Therefore, this study retrospectively investigated the resistance to antimicrobial agents in all hospitalized patients suffering from community- or nosocomial-acquired pneumonia due to S. aureus and MRSA. Methods Information from the study groups suffering from either community- or nosocomial-acquired pneumonia caused by S. aureus or MRSA was gathered by searching records from 2004 to 2014 at the HELIOS Clinic Wuppertal, Witten/Herdecke University, Germany. The findings of antibiotic resistance were analyzed after the evaluation of susceptibility testing for S. aureus and MRSA. Results Total of 147 patients (63.9%, 95% CI 57.5%–69.8%), mean age 67.9 ± 18.5 years, with pneumonia triggered by S. aureus, and 83 patients (36.1%, 95% CI 30.2%–42.5%), mean age 72.3 ± 13.8 years, with pneumonia due to MRSA. S. aureus and MRSA developed no resistance to vancomycin (P = 0.019 vs. < 0.0001, respectively) or linezolid (P = 0.342 vs. < 0.0001, respectively). MRSA (95.3%) and S. aureus (56.3%) showed a high resistance to penicillin. MRSA (87.7%) was also found to have a high antibiotic resistance against ß-lactam antibiotics, compared to S. aureus (9.6%). Furthermore, MRSA compared to S. aureus, respectively, had increased antibiotic resistance to ciprofloxacin (90.1% vs. 17.0%), cefazolin (89.7% vs. 10.2%), cefuroxime (89.0% vs. 9.1%), levofloxacin (88.2% vs. 18.4%), clindamycin (78.0% vs. 14.7%), and erythromycin (76.5% vs. 20.8%). Conclusion No development of resistance was found to vancomycin and linezolid in patients with pneumonia caused by S. aureus and MRSA. PMID

    Background The purpose of this study was to describe the experience of the Center of Drug Evaluation and Research (CDER) with expanded access of investigational drugs. Methods Multiple searches of CDER’s document tracking system were performed to identify the number, type, and indication for all expanded access requests over the 10-year time period of January 2005 through December 2014. An additional search was performed to identify all active commercial investigational drug development programs during that time period and whether or not the clinical program was placed on hold. The two searches were then cross-referenced to identify those commercial investigational drug development programs placed on clinical hold due to serious adverse events occurring within expanded access programs. Results CDER receives over 1000 applications for expanded access each year. The majority are for single patients, roughly evenly split between emergency and nonemergency use. The vast majority, 99.7%, are allowed to proceed. The incidence of clinical holds for all commercial investigational drug development programs is 7.9%, as compared to only 0.2% related to adverse events observed in patients receiving drug treatments under expanded access. Conclusions The expanded access program is viewed as a success from FDA’s perspective based on the large number of applications processed and allowed to proceed each year. However, the actual number of patients and their health care providers that desire drug treatments available under expanded access is not known. It is exceedingly rare for a serious adverse event under expanded access to affect the development program for that drug. PMID:27917324

    Over the past 10 years, the field of health services and management research has seen renewed interest in the use of qualitative research methods. This article examines the volume and characteristics of qualitative research articles published in nine major health services and management journals between 1998 and 2008. Qualitative research articles comprise 9% of research articles published in these journals. Although the publication rate of qualitative research articles has not kept pace with that of quantitative research articles, citation analysis suggests that qualitative research articles contribute comparably to the field’s knowledge base. A wide range of policy and management topics has been examined using qualitative methods. Case study designs, interviews, and documentary sources were the most frequently used methods. Half of qualitative research articles provided little or no detail about key aspects the study’s methods. Implications are discussed and recommendations are offered for promoting the publication of qualitative research. PMID:20675353

    Creutzfeldt-Jakob disease is a rare, but rapidly progressive, up to now untreatable and fatal neurodegenerative disorder. Clinical diagnosis of Creutzfeldt-Jakob disease (CJD) is difficult; however, it can be facilitated by suitable biomarkers. Aim of the present study is to compare levels of cerebrospinal fluid biomarkers (total tau protein, phosphorylated-tau protein, protein 14-3-3 and amyloid beta) in Slovak population of CJD suspect cases, retrospectively in over a 10-year period. One thousand three hundred sixty-four CSF samples from patients with suspect CJD, forming a homogenous group in terms of geographical as well as of equal transport conditions, storage and laboratory processing, were analysed. Definite diagnosis of Creutzfeldt-Jakob disease was confirmed in 101 patients with genetic form, and 60 patients with its sporadic form of the disease. Specificity of protein 14-3-3 and total tau in both forms CJD was similar (87 % for P14-3-3/85 % for total tau), sensitivity to P 14-3-3 and total tau was higher in sporadic Creutzfeldt-Jakob disease (sCJD) (90/95 %) than in genetic Creutzfeldt-Jakob disease (gCJD) (89/74 %). As expected, the total tau levels were significantly higher in CJD patients than in controls, but there was also significant difference between gCJD and sCJD (levels in gCJD were lower; p = 0.003). There was no significant difference in p-tau and Aβ 1-42 levels neither between both CJD forms nor between CJD patients and control group.

    This study has been conducted to estimate the occurrence of Cryptosporidium oocysts in water supplies in the Metropolitan area of Seoul, South Korea, for 10 years from 2000 to 2009. Water samples were collected quarterly at 6 intakes in the Han River and its largest stream and 6 conventional Water Treatment Plants (WTPs) serving drinking water for 10 million people of Seoul. Cryptosporidium oocysts were found in 22.5% of intake water samples and arithmetic mean was 0.65 oocysts/10 L (range 0-22 oocysts/10 L). Although the annual mean of oocyst number was as low as 0.04-1.90 oocysts/10 L, 3 peaks in 2004 and 2007 were observed and the pollution level was a little higher in winter. The lowest density was observed at Paldang intake and the pollution level increased at Kuui and Jayang intakes. At the end of the largest stream, oocysts were found in 70% of collected samples (mean 5.71 oocysts/10 L) and it seemed that its joining the Han River resulted in the increase at Kuui intake and downstream. Oocyst removal by physical process exceeded 2.0-2.3 log and then all finished water samples collected at 6 WTPs were negative for Cryptosporidium in each 100 L sample for 10 years. These results suggested that domestic wastewater from the urban region could be a source of Cryptosporidium pollution and separating sewage systems adjacent to the intakes could be meaningful for some intakes having weakness related to parasitological water quality.

    This paper examines trends in the nursing labour market in Canada over a period of dramatic fluctuations in hospital expenditures. We add to previous analysis that covered the period 1991-1996 and use Census data from 2001 to examine the relationship between hospital expenditure and nurse labour force participation. We find that shifts in labour force participation over the period 1991-2001 had a significant impact on the nursing supply in Canada. Individuals who were trained in nursing but were working outside the profession in 1996 because of budgetary reductions and layoffs in hospitals had largely been reabsorbed back into nursing jobs by 2001. Our analysis provides further empirical evidence that the labour force participation among individuals trained in nursing is driven to a large extent by demand-side factors.

    A previous study on the effects of experimental hydraulic clam dredging on seabed habitat and commercial bivalve populations revealed a lack of recovery after a 3-year post-dredging period (1998-2001) on a deep (65-75 m) offshore sandy bank on the Scotian Shelf, Canada. Follow-up sidescan sonar surveys were carried out 5 and 10 years after dredging (2003, 2008) in order to identify long-term processes of seabed recovery. Grab sampling was carried out 10 years after dredging to identify post-dredging commercial bivalve recruitment. Changes in the seafloor, including dredge tracks, were documented with a series of 7 sidescan sonar surveys between 1998 and 2008. A sediment mobility model was constructed based on modeled tidal current and hindcast wave data over this time period to quantify natural seabed disturbance and interpret changes to the dredge tracks mapped by sidescan sonar surveys. The model indicated that tidal currents had minimal effect on sediment mobilization. The main driving force associated with re-working of surficial sediments as evidenced by deterioration of dredge tracks in sonograms was annual fall/winter storms. While the annual frequency of storms and associated wave heights was variable, the observations and sediment mobility calculations suggest that the most influential variable is the magnitude of individual large storms, specifically storms with a significant wave height of ∼11 m. These storms are capable of generating mobile sediment layers of 20-30 cm thickness, equivalent to the dredge blade cutting depth. It appears that, with minor exceptions, sediment properties have returned to pre-dredging conditions 10 years after dredging in this habitat. Based on known age-length relationships, the four commercial bivalve species showed very low recruitment at the experimental site over the 10-year post-dredging period. However, this is unlikely due to a dredging effect since a similar pattern was observed in non-dredged areas.

  3. A bibliometric analysis of toxicology research productivity in Middle Eastern Arab countries during a 10-year period (2003–2012)

    Background Bibliometric studies are increasingly being used for research assessment by involving the application of statistical methods to scientific publications to obtain the bibliographics for each country. The main objective of this study was to analyse the research productivity originating from 13 Middle Eastern Arab (MEA) countries with articles published in toxicology journals. Methods Data from January 1, 2003 till December 31, 2012 were searched for documents with specific words in the toxicology field as a “source title” in any one of the 13 MEA countries. Research productivity was evaluated based on a methodology developed and used in other bibliometric studies. Research productivity was adjusted to the national population and nominal gross domestic product (GDP) per capita. Results Documents (n = 1,240) were retrieved from 73 international peer-reviewed toxicology journals. The h-index of the retrieved documents was 39. Of the 73 journal titles, 52 (69.9%) have their IF listed in the ISI Journal Citation Reports 2012; 198 documents (16.0%) were published in journals that had no official IF. After adjusting for economy and population power, Egypt (193.6), Palestine (18.1), Kingdom of Saudi Arabia (KSA) (13.0), and Jordan (11.5) had the highest research productivity. Countries with large economies, such as the Kuwait, United Arab Emirates (UAE), and Oman, tended to rank relatively low after adjustment of GDP. The total number of citations at the time of data analysis (August 4, 2013) was 10,991, with a median (interquartile range) of 4 (1–11). MEA collaborated more with countries in the MEA regions (16.7%), especially KSA, Egypt, and UAE, followed by Europe (14.4%), especially with the United Kingdom and Germany. Conclusions The present data show a promising rise and a good start for toxicology research activity in toxicology journals in the Arab world. Research output is low in some countries, which can be improved by investing in more

    The National Programme for the Elimination of Lymphatic Filariasis is underway in the endemic districts of Tamil Nadu State, South India, since 2001. Annual mass drug administration (MDA) was carried out by the state health department to all eligible individuals. The impact of MDAs on transmission parameters was evaluated in 2 revenue blocks, viz, one with DEC alone and the other with a combination of albendazole. After 10 years with 6 annual MDAs, the transmission indices reached low levels in both treatment arms, but still persisted. However, the DEC alone arm showed higher transmission rates, compared to the DEC+ALB arm. Few villages which demonstrated persistent transmission need to be targeted with an additional control measure viz, vector control, to achieve LF elimination. It is evident from the 10 year period of the study that inclusion of albendazole along with DEC has significantly reduced the transmission indices to almost nil level, as compared to DEC alone.

    Background. Stevens-Johnson syndrome (SJS) and/or toxic epidermal necrolysis (TEN) are uncommon and life-threatening drug reaction associated with a high morbidity and mortality. Objective. We studied SJS and/or TEN by conducting a retrospective analysis of 87 patients treated during a 10-year period. Methods. We conducted a retrospective review of the records of all patients with a diagnosis of SJS and/or TEN based on clinical features and histological confirmation of SJS and/or TEN was not available at the Department of Medicine, Vajira hospital, Bangkok, Thailand. The data were collected from two groups from 2003 to 2007 and 2008 to 2012. Results. A total of 87 cases of SJS and/or TEN were found, comprising 44 males and 43 females whose mean age was 46.5 years. The average length of stay was 17 days. Antibiotics, anticonvulsants, and allopurinol were the major culprit drugs in both groups. The mean SCORTEN on admission was 2.1 in first the group while 1.7 in second the group. From 2008 to 2012, thirty-nine patients (76.5%) were treated with corticosteroids while only eight patients (22.2%) were treated between 2003 and 2007. The mortality rate declined from 25% from the first group to 13.7% in the second group. Complications between first and second groups had no significant differences. Conclusions. Short-term corticosteroids may contribute to a reduced mortality rate in SJS and/or TEN without increasing secondary infection. Further well-designed studies are required to compare the effect of corticosteroids treatment for SJS and/or TEN.

    The aim of this study was to histologically and histomorphometrically analyze the peri-implant tissue reactions and the bone-titanium interface in loaded Ankylos implants retrieved after loading periods of longer than 1 year. The archives of the Implant Retrieval Center of the Dental School of the University of Chieti- Pescara were searched for Ankylos implants retrieved from humans after a loading period of longer than 1 year. A total of four implants were found: one had been retrieved after 3 years (Friadent plus surface), two after 3.5 years (Friadent plus surface), and one after 10 years (Deep Profile surface). All implants had been loaded; two had been loaded immediately. One implant was retrieved after fracture, one was retrieved after fracture of the superstructure, and the other two were retrieved because of bone resorption with or without infection. Compact bone with few small marrow spaces was present around the three implants retrieved after 3 and 3.5 years; trabecular bone was present around the implant retrieved after 10 years. The bone-implant contact of the three best threads was 35% for the implant retrieved after 10 years, 99% for the implant retrieved after 3 years, and 100% for the implants retrieved after 3.5 years. No untoward effects were present at the interface, and a high bone-implant contact was present around the implants with the microstructured surface. The data show that these implants had the potential to maintain osseointegration under long-term function with continuous and ongoing bone remodeling.

    Background We identified predominant vaginal microbiota communities, changes over time, and how this varied by HIV status and other factors in a cohort of 64 women. Methods Bacterial DNA was extracted from reposited cervicovaginal lavage samples collected annually over an 8–10 year period from Chicago Women’s Interagency HIV Study participants: 22 HIV-negative, 22 HIV-positive with stable infection, 20 HIV-positive with progressive infection. The vaginal microbiota was defined by pyrosequencing of the V1/V2 region of the 16S rRNA gene. Scheduled visits included Bacterial vaginsosis (BV) screening; clinically detected cases were referred for treatment. Hierarchical clustering identified bacterial community state types (CST). Multinomial mixed effects modeling determined trends over time in CST, by HIV status and other factors. Results The median follow-up time was 8.1 years (range 5.5–15.3). Six CSTs were identified. The mean relative abundance (RA) of Lactobacillus spp. by CST (with median number of bacterial taxa) was: CST-1–25.7% (10), CST-2–27.1% (11), CST-3–34.6% (9), CST-4–46.8% (9), CST-5–57.9% (4), CST-6–69.4% (2). The two CSTs representing the highest RA of Lactobacillus and lowest diversity increased with each additional year of follow-up (CST-5, adjusted odds ratio (aOR) = 1.62 [95% CI: 1.34–1.94]; CST-6, aOR = 1.57 [95 CI: 1.31–1.89]), while the two CSTs representing lowest RA of Lactobacillus and higher diversity decreased with each additional year (CST-1, aOR = 0.89 [95% CI: 0.80–1.00]; CST-2, aOR = 0.86 [95% CI: 0.75–0.99]). There was no association between HIV status and CST at baseline or over time. CSTs representing lower RA of Lactobacillus were associated with current cigarette smoking. Conclusions The vaginal microbial community significantly improved over time in this cohort of women with HIV and at high risk for HIV who had regular detection and treatment referral for BV.

    Lytic bacteriophages are hypothesized to contribute to the seasonality and duration of cholera epidemics in Bangladesh. However, the bacteriophages contributing to this phenomenon have yet to be characterized at a molecular genetic level. In this study, we isolated and sequenced the genomes of 15 bacteriophages from stool samples from cholera patients spanning a 10-year surveillance period in Dhaka, Bangladesh. Our results indicate that a single novel bacteriophage type, designated ICP1 (for the International Centre for Diarrhoeal Disease Research, Bangladesh cholera phage 1) is present in all stool samples from cholera patients, while two other bacteriophage types, one novel (ICP2) and one T7-like (ICP3), are transient. ICP1 is a member of the Myoviridae family and has a 126-kilobase genome comprising 230 open reading frames. Comparative sequence analysis of ICP1 and related isolates from this time period indicates a high level of genetic conservation. The ubiquitous presence of ICP1 in cholera patients and the finding that the O1 antigen of lipopolysaccharide (LPS) serves as the ICP1 receptor suggest that ICP1 is extremely well adapted to predation of human-pathogenic V. cholerae O1.

    This case report presents a histologic and histomorphometric evaluation of the peri-implant tissues of a HA-coated implant retrieved due to peri-implantitis after a 10-year loading period. The implant was retrieved with a trephine and treated to obtain thin ground sections. At low-power magnification mostly compact, mature bone with small marrow spaces could be observed at the interface with the implant. The coating was always present in the areas where bone was detected, the bone was always in close contact with the coating, and there was no detachment between the metal and coating or between the coating and bone. Areas of bone remodeling were demonstrated by the presence of many secondary osteons and reversal lines close to the implant surface. The bone-implant contact percentage was 36.3% ± 1.2%. The percentage of the implant surface covered by the HA coating without bone, where bone may have detached during retrieval, was 32.6% ± 2.8%. This HA-coated implant, continued to demonstrate more than adequate BIC after many years of function and the potential to maintain osseointegration in the long term.

    There are a multitude of techniques to undertake tonsillectomy, with hot techniques such as diathermy and coblation being associated with a higher risk of secondary haemorrhage. The UK National Prospective Tonsillectomy Audit (2004) advocated cold steel dissection and ties to be the gold standard. This prospective observational study investigates the trends in tonsillectomy techniques across Wales in the last decade to establish if surgeons have adhered to this national guidance. Data relating to tonsillectomy were extracted over a 10-year period from 1 January 2003 to 31 December 2012 from the Wales Surgical Instrument Surveillance Programme database. A total of 19,195 patients were included. Time-series analysis using linear regression showed there was an increase in the number of bipolar diathermy tonsillectomies by 84% (Pearson's r = 0.762, p = 0.010) and coblation tonsillectomies by 120% (r = 0.825, p = 0.003). In contrast, there was a fall in the number of cold steel dissection tonsillectomies with ties by 60% (r = −0.939, p < 0.001). This observational study suggests that the use of bipolar and coblation techniques for tonsillectomy has increased. This deviation from national guidance may be due to these techniques being faster with less intraoperative bleeding. Further study for the underlying reasons for the increase in these techniques is warranted. PMID:26693228

    Long-term monitoring of restoration projects aims to determine long-term sustainability and stability of restored systems. In coastal wetlands, one indicator of restoration of ecosystem function can be seen with organic matter (specifically carbon) accretion. SL-15, a spoil island in Fort Pierce, Fl was restored in 2005, and has been monitored for return to natural condition over the last 10 years.. To assess sediment carbon accretion, sediment cores were collected in a set of eight plots, located on the SL-15 mangrove island and the surrounding seagrass recruitment area. These were analyzed for organic carbon, microbial biomass carbon, extractable carbon, and total nitrogen. The biogeochemical data collected in the previous year was compared to data collected in 2005-2007. Vegetation surveys were also completed to show the build-up of organic material in accordance with vegetation shift over the 9-year period. From this information, a trajectory has been formulated on organic carbon accretion and vegetation shift from the time of orginal restoration activities. By comparison to control sites nearby, realistic estimates of time required to reach natural levels of carbon and vegetation community structure can be calculated..

    In developed countries, pregnancy-related listeriosis accounts for 20–43% of total invasive listeriosis. This work describes the first pregnancy-related listeriosis survey in Italy based on two data sources, that is, mandatory notification system and regional laboratory-based network. Out of 610 listeriosis cases reported over a 10-year period, 40 were pregnancy-related (6.6%). Among these, 29 pregnancy-related isolates were available and have been analysed with serotyping, Pulsed-Field Gel Electrophoresis, and Multi-Virulence-Locus Sequence Typing. No maternal fatality was recorded, but 11 (29.7%) pregnancies resulted in a foetal death, a miscarriage, or a birth of a foetus dying immediately after birth. The average incidence of pregnancy-related listeriosis was 4.3 cases per 100000 births, and the proportion of pregnancy-associated listeriosis among ethnic minorities was significantly higher compared to the general population (30.0% versus 3.5%, P < 0.01). L. monocytogenes isolates belonged to serotypes 1/2a, 1/2b, and 4b, with the latter significantly more prevalent among pregnancy-related isolates. Twenty different pulsotypes were distinguished and 16 out of the 29 isolates were classified into seven clusters. A total of 16 virulence types (VTs) were identified. Five VTs accounted for 45% of the total cases and coincided with those of previously described Epidemic Clones (ECs) of L. monocytogenes.

    The performance of high-resolution CZE for determination of carbohydrate-deficient transferrin (CDT) in human serum based on internal and external quality data gathered over a 10-year period is reported. The assay comprises mixing of serum with a Fe(III) ion-containing solution prior to analysis of the iron saturated mixture in a dynamically double-coated capillary using a commercial buffer at alkaline pH. CDT values obtained with a human serum of a healthy individual and commercial quality control sera are shown to vary less than 10%. Values of a control from a specific lot were found to slowly decrease as function of time (less than 10% per year). Furthermore, due to unknown reasons, gradual changes in the monitored pattern around pentasialo-transferrin were detected, which limit the use of commercial control sera of the same lot to less than 2 years. Analysis of external quality control sera revealed correct classification of the samples over the entire 10-year period. Data obtained compare well with those of HPLC and CZE assays of other laboratories. The data gathered over a 10-year period demonstrate the robustness of the high-resolution CZE assay. This is the first account of a CZE-based CDT assay with complete internal and external quality assessment over an extended time period.

    Poly- and perfluoroalkyl substances (PFASs) are a group of man-made fluorinated chemicals which have, at background levels, been associated with negative health effects in humans. Thus far, most human biomonitoring studies have evaluated the general change in PFAS concentration over time by continuously testing various individuals. This is one of the few studies to report the longitudinal trend of a range of PFAS concentrations in humans. In addition, this is the first known longitudinal study to include a large background level exposed cohort of both men and women with the same age and location who were repeatedly sampled from 2001 to 2014. The longitudinal change in concentration of eight PFASs detected in serum collected from the Prospective Investigation of the Vasculature in Uppsala Seniors (PIVUS) cohort were determined and compared to results from general population studies. The sex-dependent changes in PFAS concentrations over time were also assessed. Serum was sampled from the same individuals at ages 70 (collection period 2001-2004), 75 (2006-2009) and 80 (2011-2014,). Eight (C6-11) of fourteen (C4-13) analyzed PFASs were usually detected in over 75% of individuals and assessed using a random effects (mixed) model. In the 579 individuals attending all three examinations, PFOSA and PFOS concentrations significantly decreased, while the remaining six PFASs significantly increased between ages 70 and 75. However, between ages 75 and 80 all PFAS concentrations significantly decreased. Overall from age 70 to 80, concentrations of PFHxS, PFUnDA, PFNA, and PFDA showed a significant increase (7% to 34%), whereas concentrations of PFOSA, PFHpA, PFOS, and PFOA (-75% to -27%) significantly decreased. Over time PFHxS concentrations increased more among women, while PFHpA concentrations showed a greater decrease among men. From age 70 to age 80, spanning from 2001-2004 to 2011-2014, the PIVUS cohort showed decreases in circulating levels of some PFASs phased out of

    Background: Acinetobacter baumannii has emerged as an important pathogen causing a variety of infections. Using data from the China Surveillance of Antimicrobial Resistance Program conducted biennially, we investigated the secular changes in the resistance of 2917 isolates of A. baumannii from 2004 to 2014 to differ antimicrobial agents. Methods: Pathogen samples were collected from 17 to 20 hospitals located in the eastern, central, and western regions of China. Minimum inhibitory concentrations (MICs) were determined by a 2-fold agar dilution method, and antimicrobial susceptibility was established using the 2014 Clinical Laboratory Standards Institute-approved breakpoints. Isolates not susceptible to all the tested aminoglycosides, fluoroquinolones, β-lactams, β-lactam/β-lactam inhibitors and carbapenems were defined as extensively drug resistant. Results: The rates of nonsusceptibility to common antimicrobial agents remained high (>65%) over the years with some fluctuations to certain agents. The prevalence of imipenem-resistant A. baumannii (IRAB) increased from 13.3% in 2004 to 70.5% in 2014 and that of extensively drug-resistant A. baumannii (XDRAB) increased from 11.1% in 2004 to 60.4% in 2014. The activity of tigecycline was stable with MIC90 ≤4 mg/L against A. baumannii from 2009 to 2014. Susceptibility to colistin remained high (97.0%) from 2009 to 2014. The prevalence of XDRAB increased in all the three surveillance regions over the years and was significantly higher in Intensive Care Unit (ICU) wards than non-ICU wards. Conclusions: This longitudinal multicenter surveillance program revealed the nationwide emergence of A. baumannii in China and showed a significant increase in prevalence from 2004 to 2014. High levels of bacterial resistance were detected among samples collected from clinical settings in China, with IRAB and XDRAB being especially prevalent. This study will help to guide empirical therapy and identify at-risk groups requiring more

  17. 10-year survival of total ankle arthroplasties

    PubMed Central

    2011-01-01

    Background and purpose There is an ongoing need to review large series of total ankle replacements (TARs) for monitoring of changes in practice and their outcome. 4 national registries, including the Swedish Ankle Register, have previously reported their 5-year results. We now present an extended series with a longer follow-up, and with a 10-year survival analysis. Patients and methods Records of uncemented 3-component TARs were retrospectively reviewed, determining risk factors such as age, sex, and diagnosis. Prosthetic survival rates were calculated with exchange or removal of components as endpoint—excluding incidental exchange of the polyethylene meniscus. Results Of the 780 prostheses implanted since 1993, 168 (22%) had been revised by June 15, 2010. The overall survival rate fell from 0.81 (95% CI: 0.79–0.83) at 5 years to 0.69 (95% CI: 0.67–0.71) at 10 years. The survival rate was higher, although not statistically significantly so, during the latter part of the period investigated. Excluding the STAR prosthesis, the survival rate for all the remaining designs was 0.78 at 10 years. Women below the age of 60 with osteoarthritis were at a higher risk of revision, but age did not influence the outcome in men or women with rheumatoid arthritis. Revisions due to technical mistakes at the index surgery and instability were undertaken earlier than revisions for other reasons. Interpretation The results have slowly improved during the 18-year period investigated. However, we do not believe that the survival rates of ankle replacements in the near future will approach those of hip and knee replacements—even though improved instrumentation and design of the prostheses, together with better patient selection, will presumably give better results.

  19. Swift: 10 Years of Discovery

    NASA Astrophysics Data System (ADS)

    The conference Swift: 10 years of discovery was held in Roma at La Sapienza University on Dec. 2-5 2014 to celebrate 10 years of Swift successes. Thanks to a large attendance and a lively program, it provided the opportunity to review recent advances of our knowledge of the high-energy transient Universe both from the observational and theoretical sides. When Swift was launched on November 20, 2004, its prime objective was to chase Gamma-Ray Bursts and deepen our knowledge of these cosmic explosions. And so it did, unveiling the secrets of long and short GRBs. However, its multi-wavelength instrumentation and fast scheduling capabilities made it the most versatile mission ever flown. Besides GRBs, Swift has observed, and contributed to our understanding of, an impressive variety of targets including AGNs, supernovae, pulsars, microquasars, novae, variable stars, comets, and much more. Swift is continuously discovering rare and surprising events distributed over a wide range of redshifts, out to the most distant transient objects in the Universe. Such a trove of discoveries has been addressed during the conference with sessions dedicated to each class of events. Indeed, the conference in Rome was a spectacular celebration of the Swift 10th anniversary. It included sessions on all types of transient and steady sources. Top scientists from around the world gave invited and contributed talks. There was a large poster session, sumptuous lunches, news interviews and a glorious banquet with officials attending from INAF and ASI. All the presentations, as well as several conference pictures, can be found in the conference website (http://www.brera.inaf.it/Swift10/Welcome.html). These proceedings have been collected owing to the efforts of Paolo D’Avanzo who has followed each paper from submission to final acceptance. Our warmest thanks to Paolo for all his work. The Conference has been made possible by the support from La Sapienza University as well as from the ARAP

    2016-01-01

    Over the past 10 years, the development and convergence of microbial opsin engineering, modular genetic methods for cell-type targeting and optical strategies for guiding light through tissue have enabled versatile optical control of defined cells in living systems, defining modern optogenetics. Despite widespread recognition of the importance of spatiotemporally precise causal control over cellular signaling, for nearly the first half (2005–2009) of this 10-year period, as optogenetics was being created, there were difficulties in implementation, few publications and limited biological findings. In contrast, the ensuing years have witnessed a substantial acceleration in the application domain, with the publication of thousands of discoveries and insights into the function of nervous systems and beyond. This Historical Commentary reflects on the scientific landscape of this decade-long transition. PMID:26308982

    The most important diseases of farmed penaeid shrimp have infectious aetiologies. Among these are diseases with viral, rickettsial, bacterial, fungal and parasitic aetiologies. Diagnostic methods for these pathogens include the traditional methods of gross pathology, histopathology, classical microbiology, animal bioassay, antibody-based methods, and molecular methods using DNA probes and DNA amplification. While methods using clinical chemistry and tissue culture are standard methods in veterinary and human diagnostic laboratories, the former has not been routinely applied to the diagnosis of penaeid shrimp diseases and the latter has yet to be developed, despite considerable research and development efforts that have spanned the past 40 years. No continuous shrimp cell lines, or lines from other crustaceans, have been developed. Hence, when molecular methods began to be routinely applied to the diagnosis of infectious diseases in humans and domestic animals in the mid- to late 1980s, the technology was applied to the diagnosis of certain important diseases of penaeid shrimp for which only classical diagnostic methods were previously available. A DNA hybridization assay for the parvovirus IHHNV was the first molecular test developed for a shrimp disease. This was followed within a year by the first PCR test for MBV, an important baculovirus disease of shrimp. Today, shrimp disease diagnostic laboratories routinely use molecular tests for diagnostic and surveillance purposes for most of the important penaeid shrimp diseases.

    The mathematical principle of weighting averages to determine the most appropriate numerical outcome is well established in economic and social studies. It has seen little application in forensic dentistry. This study re-evaluated the data from a previous study of age assessment at the 10 year threshold. A semiautomatic process of weighting averages by n-td, x-tds, sd-tds, se-tds, 1/sd-tds, 1/se-tds was prepared in an Excel worksheet and the different weighted mean values reported. In addition the Fixed Effects and Random Effects models for Meta-Analysis were used and applied to the same data sets. In conclusion it has been shown that the most accurate age estimation method is to use the Random Effects Model for the mathematical procedures.

    In recent years cardiovascular diseases were the second most common cause of death worldwide. Therefore, the consumption of cardiovascular drugs is high, which might result in an increase of them in the environment. The major source of aquatic environmental contamination is still effluents of wastewater treatment plants (WWTPs). Unfortunately removal of cardiovascular active compounds and/or their metabolites in WWTP is still unsatisfactory. Among microbial and abiotic degradation of these compounds during wastewater processes, photolysis and photodegradation of cardiovascular drugs also play an important role. New formed compounds may be more toxic or retain the properties of parent compounds. Thus the main goal of this paper was to provide a detailed and comprehensive review of used analytical methods, coupled to liquid chromatography-tandem mass spectrometry, to determine the presence of cardiovascular compounds in surface waters as well as WTTPs effluents and influents. Exhaustive preparation for mass spectrometry detection and quantitation including samples pre-treatment, and the common problem of the matrix effect are thoroughly explored in this paper. Additionally, the article provides some hints in respect of recently noted problematic issue related to the availability of specific standards for the analysis of drug's metabolites. Furthermore, information concerning the metabolism of cardiovascular active compounds including differences in metabolism within enantiomers is described. This article also touches on the problems associated with environmental risk assessment due to the presence of cardiovasculars in the environment. The paper also tries to explain differences in concentrations among cardiovascular compounds between countries worldwide.

    Background Interlocks reduce driving-under-the-influence (DUI) recidivism by 64%, but offenders resist installing them, preferring to risk driving while their driver’s licenses are revoked. One method of motivating offenders to install an interlock is require it for reinstatement of their driver’s license. This report updates an earlier evaluation of the administrative reinstatement interlock program (ARIP) procedure implemented in Florida in 2002. Method Driver records and interlock program records covering 120,000 DUI offenders were followed over 10 years. The flow through the sanction system—conviction, reinstatement, interlock program, and postinterlock period—is described. Logistical regression was used to identify the characteristics of offenders who installed interlocks, and survival analysis was used to evaluate the recidivism of offenders in the various stages in the ARIP. Results At any given time, approximately one third of the convicted offenders were serving their license-revocation periods. Half of the offenders who completed their revocation periods remain unqualified for reinstatement because they do not fulfill other requirements. ARIP offenders who do qualify for reinstatement and install interlocks have lower recidivism rates while the devices are on their vehicles. Conclusions After 10 years, Florida’s ARIP is a mature system that succeeds in forcing all offenders in the program who qualify for reinstatement to install an interlock for at least 6 months. However, half of all offenders who complete their mandatory revocation period are either unable to, or choose not to, qualify for reinstatement. PMID:23442206

    This article examines the methods and dynamics of packaging multiple sources of wage and nonwage income as a means of making ends meet over a 10-year period among a sample of displaced steelworkers who lost jobs as a result of plant closings in the 1980s and then experienced extensive downward mobility. The study tracked changes in the respondents' income and employment over a decade, the dynamics of their use of social services, their pooling of a variety of income sources, and the use of social assistance to supplement low wages. The study found that among this sample income packaging was a universal economic strategy and that use of social services did not affect later employment and earnings.

    Background. Campylobacter bacteremia is an uncommon condition, usually diagnosed in elderly and immunocompromised patients. Methods. Blood culture isolates and clinical information were collected for patients with diagnoses of Campylobacter jejuni or Campylobacter coli bacteremia in Finland from 1998 through 2007. Bacterial species were identified by means of polymerase chain reaction analysis, and minimal inhibitory concentrations for ciprofloxacin, clindamycin, doxycycline, erythromycin, gentamicin, meropenem, and metronidazole were determined with an agar dilution method. Medical records and mortality data within 1 year after the bacteremic episode were reviewed. Results. The study included 76 patients (median age, 46 years), for whom bacterial isolates (C. jejuni in 73, C. coli in 3) and clinical information were available. Most patients (70%) had no significant underlying diseases. The majority (82%) of the isolates were susceptible for all antimicrobial agents tested. However, antimicrobial therapy seemed to have only a limited effect, because no differences could be detected between patients with appropriate empirical antimicrobial treatment and those with delayed appropriate, inappropriate, or no antimicrobial therapy, either in the duration of hospitalization (median, 4 days for both groups) or in attributable mortality. The outcome of the infection was severe in 4 patients infected with C. jejuni; 2 died within 30 days, spondylodiscitis developed in 1, and Guillain-Barré syndrome developed in 1. Conclusions. C. jejuni and C. coli bacteremia occurred mainly in moderately young individuals without severe underlying diseases. The bacterial isolates were predominantly susceptible to antimicrobial agents, and the outcome of the disease was typically good, regardless of appropriate or inappropriate antimicrobial treatment given in the hospital.

    Using the forward period analysis (FPA), we obtain the period of a Morse oscillator and mathematical pendulum system, with the accuracy of 100 significant digits. From these results, the long-term [0, 1060] (time unit) solutions, ranging from the Planck time to the age of the universe, are computed reliably and quickly with a parallel multiple-precision Taylor series (PMT) scheme. The application of FPA to periodic systems can greatly reduce the computation time of long-term reliable simulations. This scheme provides an efficient way to generate reference solutions, against which long-term simulations using other schemes can be tested. PMID:27727295

    Rheumatoid arthritis remains a chronic disabling disorder in which medical and surgical intervention may provide amelioration but not cure. In this study a cohort of 123 rheumatoid patients were followed for a period of 10 years from the time of prescription of their initial second-line agent. The workload involved in managing articular, extra-articular and intercurrent disease in these patients has been documented and outcome in relation to continued use of 'disease modifying' therapy evaluated. At 10 years 24 patients (20 per cent) had died and 7 (5 per cent) were not traced; of the 92 (75 per cent) who were assessed, three had become wheelchairbound, two for reasons other than rheumatoid arthritis. Seventy-one per cent of patients required joint surgery, 36 per cent management of peptic ulcer and 45 per cent experienced major episodes of sepsis. Analysis of the results in the 92 patients who were evaluated at 10 years showed significant improvement in Ritchie articular index, pain score, morning stiffness, haemoglobin, platelets, ESR, total globulins, IgG and IgM. Grip strength and Lee functional index showed a trend towards deterioration which did not reach significance. Sixty-seven (73 per cent) of the 92 patients remained on a second- or third-line agent at 10 years (median duration of treatment 107 months); 25 (27 per cent) were not receiving such therapy (median duration of second- and third-line therapy 13 months). The group remaining on treatment showed significant improvement similar to that of the total study group. Those not on treatment improved only for articular index; Lee functional index deteriorated significantly. There was a correlation between area under the curve for ESR over 10 years and radiological progression of disease in hands (r = 0.29, p = 0.026) and in knees and hips (r = 0.3748, p = 0.012) over the 10 year period. Radiographic score correlated well with Lee functional index at the outset and at 10 years and also with the change in

    In 1988 Bonneville Power Administration (BPA) began work on this Operations, Maintenance, and Replacement 10-Year Plan to develop a levelized program that would assure high system reliability. During the Programs in Perspective (PIP) meetings in the late summer and fall of 1988, many of the concerns to be addressed in an Operations, Maintenance, and Replacement Plan were identified. Following these PIP meetings BPA established internal work groups. During the winter and spring of 1989, these work groups developed technical background and issue papers on topics that ranged from substation maintenance to environmental protection. In addition, a customer forum group was established and met on several occasions to review work on the plan, to offer ideas and points of view, and to assure that BPA understood customer concerns. Based on recommendations from the work group reports and customer input, BPA's O M Management Team developed the draft Operations, Maintenance, and Replacement 10-Year Plan that was released for public comment during the spring of 1990. During the public review period, BPA received a number of written comments from customers and the interested public. In addition, special meetings were held with interested customers. This final Operations, Maintenance, and Replacement 10-Year Plan reflects BPA's response to customers and interested public on each topic discussed in the 10-Year Plan. The plan is a distillation of BPA's strategies to achieve a levelized program over 10 years.

    Purpose: To report outcomes of epikeratoplasty in keratoconus (KC), utilizing manually-prepared plano donor lenticules in terms of flattening of the cone, reduction in astigmatism and improvement in the visual acuity. Materials and Methods: Patients with KC, having visual acuity <20/200, astigmatism >12 diopters (D) but without corneal opacity underwent epikeratoplasty, using manually prepared plano donor lenticules from fresh or M.K preserved corneas, between 1990 - 2000 and followed for 10 years, were included in this report. Visual acuity slit-lamp-biomicroscopy, keratometry, and refraction were performed at 8 weeks, 12 weeks, and 6 months for all 59 patients. The same were carried out at 1 year, 5 years, and 10 years depending upon the availability of the patient for that period. Results: Of the 59 patients, only 26 were available for follow-up after 10 years. At 3 months, 1 year and 5 years, best corrected visual acuity of (BCVA) ≥20/60 were achieved in 84.7%, 84.4% and 80.3% of eyes, respectively. BCVA was 73% at 10-year follow- up, which was due to the presence of posterior subcapsular cataract (PSC). The average keratometric astigmatism and average flattening in diopters stabilized at the end of 3 months, which remained constant at 1, 5, and 10-year follow-up. The average diopter of myopia was stabilized by 1 year, which was almost same at 10 year. Graft was clear in all but 1 eye at 10 year follow-up. Conclusion: Epikeratoplasty is a useful technique for keratoconic eyes without apical scarring who fail or unable to use contact lenses. PMID:23275216

    Background Adrenocortical carcinoma (ACC) is a rare and aggressive malignancy with limited therapeutic options beyond surgical resection. The characteristics of actual long-term survivors following surgical resection for ACC have not been previously reported. Method Patients who underwent resection for ACC at one of 13 academic institutions participating in the US Adrenocortical Carcinoma Group from 1993 to 2014 were analyzed. Patients were stratified into four groups: early mortality (died within 2 years), late mortality (died within 2–5 years), actual 5-year survivor (survived at least 5 years), and actual 10-year survivor (survived at least 10 years). Patients with less than 5 years of follow-up were excluded. Results Among the 180 patients available for analysis, there were 49 actual 5-year survivors (27%) and 12 actual 10-year survivors (7%). Patients who experienced early mortality had higher rates of cortisol-secreting tumors, nodal metastasis, synchronous distant metastasis, and R1 or R2 resections (all P < 0.05). The need for multi-visceral resection, perioperative blood transfusion, and adjuvant therapy correlated with early mortality. However, nodal involvement, distant metastasis, and R1 resection did not preclude patients from becoming actual 10-year survivors. Ten of twelve actual 10-year survivors were women, and of the seven 10-year survivors who experienced disease recurrence, five had undergone repeat surgery to resect the recurrence. Conclusion Surgery for ACC can offer a 1 in 4 chance of actual 5-year survival and a 1 in 15 chance of actual 10-year survival. Long-term survival was often achieved with repeat resection for local or distant recurrence, further underscoring the important role of surgery in managing patients with ACC. PMID:27633419

    This study was undertaken to quantify 10-year evapotranspiration (ET) in a tropical rainforest, Sarawak, Malaysia. To this aim, a simplified big-leaf model was formulated, which can consider transpiration (Et) and rainfall interception (Ei). The model was independently validated using eddy covariance fluxes, rainfall interception based on throughfall and stemflow measurements, and sap flow measurements conducted for more than two years. Consequently, our big-leaf model could successfully reproduce Et and Ei. By using the model and a 10-year meteorological data set, Et, Ei, and ET was estimated in the period between 2000 and 2009. The annual Et , Ei, and ET averaged over 10 years were estimated as 1114, 209, and 1323 mm, respectively, with the small seasonal fluctuations. The derived estimations for 10 years showed conservative year-to-year variations in Et, Ei, and ET (CV = 5-7%) against considerable year-to-year variations in annual rainfall (CV = 11%). Specific rainfall characteristics in this site could be a reason for conservative year-to-year variations in Ei. Small interannual variations in meteorological conditions and no occurrence of unusually severe drought in this study period could be a reason for the small year-to-year variations in Et. As well, we compared ET, Ei at this site with those of other tropical forests. Our forest ET was smaller than global maximum value of ET estimated in other tropical forests because of the smaller Ei, relative to annual rainfall at this site. Based on the derived characteristics of ET, we also discussed possible changes in ET, Et, and Ei in response to changes in rainfall regime at this site.

    Objectives. This retrospective clinical and radiographical study evaluated the 10-year outcome of one-visit endodontic treatment with gutta-percha and a methacrylate resin-based sealer. Methods. From an initial sample size of 180 patients, 89 patients with 175 root canals responded to a recall. Treatment outcome was based on predetermined clinical and radiographic criteria. Results. Root canals had been adequately filled to the working length in 80 teeth (89.88%), short in 6 instances (6.74%), while 3 (3.37%) with extrusion immediate postoperatively, showed no sealer in periradicular tissues. The difference in the outcomes of treatments with respect to age, gender, preoperative pulp or periapical status, the size of periapical lesions and the type of permanent restorations were not statistically significantly different (P > 0.05). Overall, 7 (7.86%) cases were considered clinically and radiographically a failure. A life table analysis showed a cumulative probability of success of 92.13% after 10 years with a 95% confidence interval of 83.0 to 94.0. Conclusions. The results of this retrospective clinical and radiographical study suggest that the tested methacrylate-resin based sealer used with gutta-percha performed similarly to other root canal sealers over a period 10 years. Clinical Implications. Considering the success rate after 10 years of this methacrylate resin-based sealer can be recommended as an alternative to other commonly used root canal sealers.

    BACKGROUND: Nasal septal surgery and rhinoplasty are controversial in children. Traditionally, an attitude of restraint has been employed by most surgeons till an empirical age of 16 to 18 years. This is to avoid the possible adverse effects that the growth spurts may have on the nose and midface region. AIM: The aim of this paper was to present the results of rhinoplasty in children in order to restore the anatomy and function or to promote normal development and outgrowth of the nose. MATERIAL AND METHODS: Ninety seven children aged 6-14, with severe nose deformities and breathing problems through the nose, were admitted for septo/rhinoplasty at the University Clinic for Ear, Nose and Throat, Faculty of Medicine, Ss Cyril and Methodius University of Skopje, Republic of Macedonia. At our Clinic, they have been observed and photographed (with parent permission) in the period of 10 years (2006-2016). The most frequent cause of these deformities was the nasal trauma in early childhood which was ignored or untreated. All of them rhino/septoplasty were indicated in accordance with the above-mentioned recommendations for rhino/septoplasty in early childhood and in adolescents. RESULTS: In 51 children and adolescents septoplasty were prepared. Mostly there was a group of younger children age from 6-10 (68%) and adolescents (32%). In the other 31 children and adolescents, septorhinoplasty was prepared. Mostly there were children older than 12 years old and adolescents (70%). Only 30% were younger than 12 years, of course with severe nasal breathing problems, nasal septal deformities and deformities of the nasal pyramid. CONCLUSION: The growth centres of the nose have to be avoided if possible; long-term nasal issues will theoretically be minimised. If the surgeon replaces it, the cartilage of the nose becomes straighter but still intact. PMID:27703562

    Background and purpose - Total knee replacement (TKR) in younger patients using cemented components has shown inferior results, mainly due to aseptic loosening. Excellent clinical results have been reported with components made of trabecular metal (TM). In a previous report, we have shown stabilization of the TM tibial implants for up to 5 years. In this study, we compared the clinical and RSA results of these uncemented implants with those of cemented implants. Patients and methods - 41 patients (47 knees) aged ≤ 60 years underwent TKR. 22 patients (26 knees) received an uncemented monoblock cruciate-retaining (CR) tibial component (TM) and 19 patients (21 knees) received a cemented NexGen Option CR tibial component. Follow-up examination was done at 10 years, and 16 patients (19 knees) with TM tibial components and 17 patients (18 knees) with cemented tibial components remained for analysis. Results - 1 of 19 TM implants was revised for infection, 2 of 18 cemented components were revised for knee instability, and no revisions were done for loosening. Both types of tibial components migrated in the first 3 months, the TM group to a greater extent than the cemented group. After 3 months, both groups were stable during the next 10 years. Interpretation - The patterns of migration for uncemented TM implants and cemented tibial implants over the first 10 years indicate that they have a good long-term prognosis regarding fixation.

    2010-01-01

    Background: Clinicians are constantly faced with the challenge of designing training programs for injured and noninjured athletes that maximize healing and optimize performance. Periodization is a concept of systematic progression—that is, resistance training programs that follow predictable patterns of change in training variables. The strength training literature is abundant with studies comparing periodization schemes on uninjured, trained, and untrained athletes. The rehabilitation literature, however, is scarce with information about how to optimally design resistance training programs based on periodization principles for injured athletes. The purpose of this review is to discuss relevant training variables and methods of periodization, as well as periodization program outcomes. A secondary purpose is to provide an anecdotal framework regarding implementation of periodization principles into rehabilitation programs. Evidence Acquisition: A Medline search from 1979 to 2009 was implemented with the keywords periodization, strength training, rehabilitation, endurance, power, hypertrophy, and resistance training with the Boolean term AND in all possible combinations in the English language. Each author also undertook independent hand searching of article references used in this review. Results: Based on the studies researched, periodized strength training regimens demonstrate improved outcomes as compared to nonperiodized programs. Conclusions: Despite the evidence in the strength training literature supporting periodization programs, there is a considerable lack of data in the rehabilitation literature about program design and successful implementation of periodization into rehabilitation programs.

That effort broke new ground and was an extensive look at the condition of Operations, Maintenance, and Replacement on BPA`s power system. This document -- the 1992 OM&R 10-Year Plan -- uses that original plan as its foundation. It takes a look at how well BPA has accomplished the challenging task set out in the 1990 Plan. The 1992 Plan also introduces the Construction Program. Construction`s critical role in these programs is explored, and the pressures of construction workload -- such as the seasonal nature of the work and the broad swings in workload between projects and years -- are discussed. The document then looks at how situations may have changed with issues explored initially in the 1990 Plan. Importantly, this Plan also surfaces and explains some new issues that threaten to impact BPA`s ability to accomplish its OM&R workload. Finally, the document focuses on the revised strategies for Operations, Maintenance, Replacement, Construction, and Environment for the 1992 to 2001 time period, including the financial and human resources needed to accomplish those strategies.

  11. Nonlinear model-based method for clustering periodically expressed genes.

    2011-01-01

    Clustering periodically expressed genes from their time-course expression data could help understand the molecular mechanism of those biological processes. In this paper, we propose a nonlinear model-based clustering method for periodically expressed gene profiles. As periodically expressed genes are associated with periodic biological processes, the proposed method naturally assumes that a periodically expressed gene dataset is generated by a number of periodical processes. Each periodical process is modelled by a linear combination of trigonometric sine and cosine functions in time plus a Gaussian noise term. A two stage method is proposed to estimate the model parameter, and a relocation-iteration algorithm is employed to assign each gene to an appropriate cluster. A bootstrapping method and an average adjusted Rand index (AARI) are employed to measure the quality of clustering. One synthetic dataset and two biological datasets were employed to evaluate the performance of the proposed method. The results show that our method allows the better quality clustering than other clustering methods (e.g., k-means) for periodically expressed gene data, and thus it is an effective cluster analysis method for periodically expressed gene data.

    2008-05-01

    A one-stop outpatient cardiology clinic was set up at the Vic General Hospital in Spain in 1996. The aims were to provide patients with a rapid response, and to ensure that, on the same day, they saw a specialist and were referred for any relevant investigations required, primarily echocardiography, exercise testing, and Holter monitoring. We report experience from 10 years of follow-up, involving 19,515 consultations. The mean waiting time for a consultation was 3 days. We analyzed the reasons for the consultations, the investigations carried out, and the reductions in follow-up visits and hospital admissions. Primary care physicians' level of satisfaction was increased by this approach. The one-stop clinic proved feasible in clinical practice and proved robust during the follow-up period. This clinical model was beneficial for patients, was highly acceptable to primary care physicians, reduced the need for patients to contact the hospital, and, possibly, reduced hospital admissions.

    Objective: Little research has examined the role of retirement in shaping late-life drinking careers, and it has generally been limited to cross-sectional designs or short-term follow-ups that emphasize group-level comparisons of retirees and nonretirees. The purpose of this study was to determine the following: (a) the effect of retired status on older adults’ 10-year within-person drinking trajectories and (b) whether age, gender, income, health, and problem-drinker status account for or moderate this effect. Method: We first estimated older adults’ (baseline M= 62 years; n = 595) 10-year within-person drinking trajectories using three successively predictive multilevel regression models: unconditional growth, retired status alone, and retired status controlling for covariates. Next, we determined whether inclusion of Retired Status × Covariate interactions would improve prediction of the trajectories. Results: Participants’ drinking frequency declined moderately over the 10-year interval, and retired status hastened the decline. However, this effect disappeared once covariates were added to the model: Baseline poorer health, lower income, and current problem-drinker status predicted steeper decline in drinking frequency, whereas former problem-drinker status predicted slower decline. Lower income and current drinking problems also predicted steeper declines in amount of alcohol consumed. There were no statistically significant or uniquely contributive interactions between retired status and age, gender, health, income, or drinking problems for predicting late-life drinking trajectories. Conclusions: Baseline health, income, and problem-drinking history are more important than retired status for predicting older adults’ long-term within-person drinking trajectories. These factors—and recency of drinking problems—should be considered in future studies of retirement and late-life drinking patterns. PMID:20230712

  16. The academic occupational physician as consultant. A 10-year perspective.

    PubMed

    McCunney, R J

    1994-04-01

    The academic community has long served the private sector in a consultant capacity in engineering and in the sciences. With respect to occupational medicine, physicians, when working for industry, have generally practiced in a health care setting. Within the past 10 years, however, the business sector has placed more attention on the health implications of its operations as a result of regulations, liability, and rising health care costs. These issues, which go beyond traditional clinical responsibilities, have furthered the need for businesses to receive strategic medical advice to effectively operate and to maintain a competitive edge. One particular business sector, the chemical industry, has been challenged seriously because of legitimate as well as perceived health risks associated with the production and use of its products. This paper describes the professional experiences over a 10-year period (1983 to 1993) of an occupational physician working as a consultant to an international chemical company. Services have related to epidemiology, health policy, toxicology, plant oversight as well as serving as a health advisor on matters involving the relation between business and health. An academic affiliation with an occupational medicine residency program has facilitated access to related occupational health professionals to assist in problem solving and research. Opportunities for consulting in occupational medicine will depend upon the nature of the organization as well as the personal and professional characteristics of the physician. Requests for these types of services, however, are likely to expand in the near future, primarily as a result of wider awareness of the implications of work on health, increased litigation, and government regulations.

    1986-01-01

    Over a 10-year period 130 patients with drug-resistant cardiac arrhythmias associated mainly with coronary artery disease and its complications were treated with amiodarone. The drug controlled all the tachyarrhythmias associated with the Wolff-Parkinson-White syndrome, 95% of the ventricular arrhythmias, including recurrent ventricular tachycardia and fibrillation, and 92% of the supraventricular arrhythmias. The maximum duration of therapy was 111 months and the mean 34 months. Side effects occurred in 34% of the patients, and there was one withdrawal from therapy per 15.3 patient-years of treatment. The commonest cause of withdrawal was nausea, which was significantly related (p less than 0.01) to a drug interaction with digoxin and diuretics. Reversible neurologic complications occurred in eight patients (6%), and acute myositis was recognized for the first time. Pulmonary infiltration developed in four patients (3%), who were receiving 600 mg of amiodarone per day. The rates of side effects and of withdrawal from therapy differed significantly between the patients whose maintenance doses were 600 and 200 mg/d, at 59% v. 6% (p less than 0.01) and 32% v. 0% (p less than 0.05) respectively. Thus, amiodarone is a very effective antiarrhythmic that can be administered over long periods with acceptable rates of side effects and withdrawal provided the minimal effective dose is used; 400 mg/d or less is desirable.

    In the last 15 years, extensive work on the Cryptophlebia leucotreta granulovirus (CrleGV) has been conducted in South Africa, initially in the laboratory, but subsequently also in the field. This culminated in the registration of the first CrleGV-based biopesticide in 2004 (hence, the 10 years of commercial use in the field) and the second one three years later. Since 2000, more than 50 field trials have been conducted with CrleGV against the false codling moth, Thaumatotibia leucotreta, on citrus in South Africa. In a representative sample of 13 field trials reported over this period, efficacy (measured by reduction in larval infestation of fruit) ranged between 30% and 92%. Efficacy was shown to persist at a level of 70% for up to 17 weeks after application of CrleGV. This only occurred where the virus was applied in blocks rather than to single trees. The addition of molasses substantially and sometimes significantly enhanced efficacy. It was also established that CrleGV should not be applied at less than ~2 × 1013 OBs per ha in order to avoid compromised efficacy. As CrleGV-based products were shown to be at least as effective as chemical alternatives, persistent and compatible with natural enemies, their use is recommended within an integrated program for control of T. leucotreta on citrus and other crops.

    Over a 10-year period, twenty-nine patients who developed false aneurysms were reviewed retrospectively. The diagnosis was delayed for as long as 7 months in the eight patients who developed aneurysms following trauma. However, all these patients had an excellent outcome after surgery. The results were also good in patients with non-infected false aneurysms after vascular reconstruction, with 17 of the 19 patients having the affected limb saved by remedial surgery. The main principle of remedial surgery was to perform the simplest surgical procedure possible. The results in infected false aneurysms were poor and management should be considered along the lines laid down for graft infection. The incidence of false aneurysms may be reduced by the use of suitable non-absorbable sutures, prevention of tension at an anastomosis and prevention of infection. However, degeneration of the arterial wall is thought to be a major cause of false aneurysms and is, of course, beyond control. Recent technical advances such as digital subtraction angiography, labelled leucocyte scanning and computed tomography have all contributed to improvements in the management of false aneurysms.

    Periodic patterns often present on document images as holograms, watermarks or guilloche elements which are mostly used for fraud protection. Localization of such patterns lets an embedded OCR system to vary its settings depending on pattern presence in particular image regions and improves the precision of pattern removal to preserve as much useful data as possible. Many document images' noise detection and removal methods deal with unstructured noise or clutter on documents with simple background. In this paper we propose a method of periodic pattern localization on document images which uses discrete Fourier transform that works well on documents with complex background.

    Background Alopecia areata (AA) is an organ-specific autoimmune disease that typically occurs in young adults. AA in the elderly is relatively rare, thus little data have been reported. Objective This study aimed to understand the clinical characteristics of AA in the elderly. Methods We performed a 10-year retrospective study of AA in the elderly who visited our dermatologic clinic from January 2002 to December 2011. A clinical review of medical records and telephone interviews were performed by two dermatologists. Results Among 1,761 patients with newly diagnosed AA, 61 (3.5%) were older than 60 years at the first visit. Among those who completed a telephone interview, 74.3% (26/35) had less than 50% of scalp-localized hair loss. There was no association between the extent of AA and hair graying (p=0.679). Favorable therapeutic response was observed in 62.9% (22/35) of cases. Conclusion AA in the elderly shows mild disease severity and favorable treatment response. There is no association between graying and the extent of AA. However, the influence of aging on the pathogenesis of AA in the elderly deserves further investigation. PMID:26273157

    2009-01-01

    Arthroscopic surgery of the hip is a well-established technique with numerous recognized indications. Despite the well-accepted nature of this procedure, there have been no outcomes studies with extended followup. We investigated the response to hip arthroscopy in a consecutive series of patients with 10 years followup. Since 1993, all patients undergoing hip arthroscopy have been assessed prospectively with a modified Harris hip score preoperatively and then postoperatively at 3, 12, 24, 60, and 120 months. A cohort of 50 patients (52 hips) was identified who had achieved 10-year followup and represent the substance of this study. There was 100% followup. The average age of the patients was 38 years (range, 14–84 years), with 27 males and 23 females. The median improvement was 25 points (preoperative, 56 points; postoperative, 81 points). Fourteen patients were converted to THA and two died. Four patients underwent repeat arthroscopy. There were two complications in one patient. The presence of arthritis at the time of the index procedure was an indicator of poor prognosis. This study substantiates the long-term effectiveness of arthroscopy in the hip as treatment for various disorders, including labral pathology, chondral damage, synovitis, and loose bodies. Arthritis is an indicator of poor long-term outcomes with these reported methods. Level of Evidence: Level IV, therapeutic study.

    Objective To review the past 10 years of research in child language or communication disorders, which are highly prevalent in the general population and comorbid with childhood psychiatric disorders. Method A literature search of 3 major databases was conducted. The child language literature, describing the domains of language development—phonology, grammar, semantics, and pragmatics—is reviewed. Results Disorders of grammar, semantics, and pragmatics, but not phonology, overlap significantly with childhood psychiatric disorders. Receptive language disorders have emerged as high-risk indicators, often undiagnosed. Language disorders and delays are psychiatric risk factors and have implications for evaluation, therapy, and research. However, they are often undiagnosed in child mental health and community settings. The research has focused mostly on monolingual English-speaking children. Conclusion Awareness of basic child language development, delay, and deviance is crucial for the practicing child and adolescent psychiatrist, who must diagnose and refer relevant cases for treatment and remediation. Future research needs to address the growing language diversity of our clinical populations. PMID:10673823

    Physicochemical properties of Fujian Yongchun aged vinegar (FYAV) and Shanxi mature vinegar (SMV) were compared in terms of the fermentation methods applied and aging periods (3, 5, 8, and 10 years), and combined E-nose/E-tongue analyses were performed to assess their flavors. Compared with submerged fermentation-derived FYAV, solid-state fermentation-derived SMV showed higher values of pH, brix, soluble solids, total phenolic content, and antioxidant activity, but not total acidity or total organic acids. Aging period resulted in an increase in pH, total phenolic content, and antioxidant activity. Principal component analysis based on E-tongue/E-nose analyses was performed to distinguish between the vinegars produced by different fermentation methods and under aging periods. Solid-state fermentation and an aging process were considered good techniques for vinegar brewing, considering the various organic acids and high levels of total phenolics and antioxidant activity.

    Objective: To clarify the clinicopathologic features of hepatocellular carcinoma (HCC) patients survived more than 10 years after radical hepatectomy. Methods: Two hundreds and fifty-two patients who underwent curative resection for HCC between January 1999 and March 2006 at Department of Hepatopancreatobiliary Surgery, Affiliated Hospital of Qingdao University were included.There were 217 male cases and 35 female cases aging from 17 to 82 years with median age of (53.8±10.5)years. Followed by March 31 2016, clinicopathologic factors in 10-year survivors and patients who died within 10 years were compared by χ(2) test, Kaplan-Meier survival analysis and Cox proportional hazards model and the prognostic factors affecting survival were identified. Results: All patients were followed-up for 4.0 to 205.7 months with median time of 53.4 months. The 10-year overall survival rate was 26%, there were 62 cases(26.2%) who survived for more than 10 years after initial hepatectomy. In survival >10-year group, the paitents with ALT<40 U/L, gamma-glutamyl transpeptidase<64 U/L, albumin≥35 g/L, without liver cirrhosis and portal hypertension, Child-Pugh grade A, no blood transfusion, AFP≤20 μg/L, tumor size ≤5.0 cm, single tumor, high differentiation, TNM stage Ⅰ and TACE negative after resection were more than the patients in survival <10-year group (P<0.05). In multivariate analysis, Child-Pugh grade A, the tumor size ≤5.0 cm and TACE negative after resection were favorable independent factors associated with 10-year survival (P<0.05). Conclusion: Based on the results of the study, Child-Pugh grade A, tumor size ≤5.0 cm and TACE negative after resection at initial hepatectomy might be biologically favorable conditions for patients surviving more than 10 years.

    A hybrid transfer-matrix finite-difference time-domain (FDTD) method is proposed for modeling the optical properties of finite-width planar periodic structures. This method can also be applied for calculation of the photonic bands in infinite photonic crystals. We describe the procedure of evaluating the transfer-matrix elements by a special numerical FDTD simulation. The accuracy of the new method is tested by comparing computed transmission spectra of a 32-layered photonic crystal composed of spherical or ellipsoidal scatterers with the results of direct FDTD and layer-multiple-scattering calculations.

  17. A method for obtaining time-periodic Lp estimates

    NASA Astrophysics Data System (ADS)

    Kyed, Mads; Sauer, Jonas

    2017-01-01

    We introduce a method for showing a prioriLp estimates for time-periodic, linear, partial differential equations set in a variety of domains such as the whole space, the half space and bounded domains. The method is generic and can be applied to a wide range of problems. We demonstrate it on the heat equation. The main idea is to replace the time axis with a torus in order to reformulate the problem on a locally compact abelian group and to employ Fourier analysis on this group. As a by-product, maximal Lp regularity for the corresponding initial-value problem follows without the notion of R-boundedness. Moreover, we introduce the concept of a time-periodic fundamental solution.

    Juvenile hyaline fibromatosis (JHF) is a rare hereditary disease with an autosomal recessive transmission. JHF is characterized by papulonodular skin lesions, osteolytic bone lesions, flexural joint contractures, and gingival hyperplasia and usually diagnosed in infancy or early childhood. JHF is thought to be a disorder of collagen metabolism and characterized by homogenous amorphous eosinophilic material and fibrous tissue. We report the case of a 14-year-old male child with multiple papulonodular skin lesions, progressive flexion contractures of joints, and severe gingival hyperplasia, with a 10-year follow-up. Although the lesions were totally removed thrice during the last 10 years, they recurred rigorously.

    2012-01-01

    Introduction: Neglected cases of osteomyelitis are not uncommon. We present a case of humerus osteomyelitis neglected for 10 years and presented with a sequestrum protruding out of the arm in the shape of a flowerpot. Such a long duration of neglect and a startling presentation are rare and have implications not only on healthcare but also reflect the socio-economic and cultural fabric of the society. Case Report: 22 year old lady presented with history of bone jutting out of right arm since last 10 years. She had a trivial injury to the arm 10 years back followed by pain and fever. She was treated by local osteopath and ‘registered’ doctors but developed wound over the arm with purulent discharge. On and off treatment with dressing was continued with symptomatic relief but in few weeks bone fragment started protruding out of the wound. The size of bone protruding from the wound increased gradually with on and off history of discharge since 10 years. Clinically a flowerpot shaped sequestrum was seen protruding from the arm. Radiographs showed a defined diaphyseal sequestrum of the humerus with continuity of the bone maintained by new bone formation. Sequestrectomy was done and at one year follow up patient was fine with no recurrence of infection Conclusions: Lack of health infrastructure, ignorance, and other social and cultural factors lead to such bad wounds. Even with such long history a single surgery for debridement and sequestrectomy was all that was needed for healing the patient.

  6. Completed double layer boundary element method for periodic suspensions

    NASA Astrophysics Data System (ADS)

    Fan, X.-J.; Phan-Thien, N.; Zheng, R.

    In this paper, a traction-based boundary element method is formulated and implemented for periodic suspensions. Hydrodynamic interaction of particles at infinity is handled by O'Brien's method (1979), which is suitably modified for the adjoint double layer using the mean field values of the traction and the background flow. After a deflation of the extreme eigenvalue -1 of the adjoint double layer operator, an iterative solution strategy is implemented, which solves for the traction field on the surfaces of a group of near-by particles sequentially. Ewald's summation technique is employed, by expressing the adjoint double layer kernel in two sums, one converges rapidly in real space, and the other, in the reciprocal Fourier space. The implementation is tested on a periodic suspension of spheres and spheroids in simple and elongated face-centred cubic arrays, and proved to be very accurate when compared to established results. New results for the intrinsic viscosities of periodic suspensions of cubes and spheroids from moderate to high volume fractions are reported. Based on the numerical data for suspensions of spheroids, a simple modification of the constitutive equation of Hinch and Leal (1972), which was derived for dilute suspension of spheroids, is reported, allowing the constitutive equation to reasonably fit the numerical data at moderate to high concentrations.

    1995-10-01

    A new actigraphic method by which periodic leg movements (PLM) can be measured is presented. Data acquistion and analysis were brought into line to distinguish short-lasting repetive leg movements from random motor restlessness. The definition of PLM follows the generally accepted criteria for PLM scoring. Thirty restless legs patients, all also suffering from PLM, were investigated three times by polysomnography, including tibialis anterior surface electromyography and actigraphy. A high correlation (reliability) was found for the number of PLM per hour spent in bed between the two methods. Furthermore, the actigraph records PLM specifically. An index of random motor restlessness is not sufficient for a reliable PLM according. In addition, periodic movements in sleep (PMS) and PLM show comparable variability in general. The actigraphic assessment of PLM, however, gives a better measure because PMS recordings may result in a substantial underestimation of PLM when sleep efficiency is reduced. This method is an ambulatory assessment tool that can also be used for screening purposes.

    2012-07-01

    There were 161 red tide events collected during the last 10 years from 2001 to 2010 in Fujian coastal waters. Comprehensive analysis was performed using statistical methods and the results indicated the following characteristics of the temporal and spatial distribution of red tide in Fujian coastal waters: (1) Outbreaks of red tide often occurred between April and September, and the peak period was in May and June. Most red tide events lasted for 2 to 4 days, and the affected area was below 50 square kilometers. The first outbreak of red tide tended to occur earlier in recent years, and the lasting time became longer. (2) There were 20 species of organisms causing the red tides in Fujian coastal waters, among which 10 species were Bacillariophyta, 9 species were Dinophyta and 1 species was Protozoa. Prorocentrum donghaiense was the most frequent cause of red tides, followed by Noctiluca scintillans, Skeletonema costatum and Chaetoceros sp.. The species caused red tides obeyed the succession law and there were always new species involved. (2) In terms of spatial distribution, outbreaks of red tides mainly occurred in the coastal waters of Ningde, Fuzhou and Xiamen. The species causing red tides were Prorocentrum donghaiense and Noctiluca in the coastal waters in the north of Pingtan, Fujian Province, Skeletonema costatum and Chaetoceros in the coastal waters in the south of Pingtan, Fujian Province. The comprehensive analysis of the characteristics of red tides during the last 10 years is expected to provide scientific and reasonable basis for the prevention, reduction and forecast of red tides in Fujian coastal waters.

    The study examined joint trajectories of methamphetamine (MA) use and substance abuse treatment utilization and identified differences among pattern groups for a sample of 348 treated for MA use. Results from group-based trajectory modeling showed that treatment utilization during the first 10 years after initiation of MA use could be categorized into three distinctive patterns: about half the MA users have a pattern of low treatment utilization; one-fourth follow a quicker-to-treatment trajectory with higher probability of treatment during the first 5 years of MA use and less treatment in the next 5 years; and one-fourth have a slower-to-treatment trajectory with more treatment during the second half of the 10-year period. Four MA use patterns were identified: consistently low use, moderate, and high use, as well as a decreasing use pattern. Periods of greater likelihood of treatment participation were associated with periods of decreasing or lower frequency of MA use.

    Dentigerous cyst is the most common odontogenic cyst. It is characterized by a unilocular radiolucent lesion that encloses permanent tooth buds or, under certain circumstances, displaced tooth buds. Buccal bony expansion and a missing tooth is the most common clinical feature. Various treatment modalities have been mentioned in the literature for management of dentigerous cysts. This article presents a left mandibular dentigerous cyst in a 10-year-old boy. Marsupialization was the treatment of choice and a denturelike space maintainer was provided. Long-term follow-up revealed good healing of the bony lesion. How to cite this article Bhardwaj B, Sharma S, Chitlangia P, Agarwal P, Bhamboo A, Rastogi K.

    Macrophagic myofasciitis (MMF) is an uncommon inflammatory disorder of muscle believed to be due to persistence of vaccine-derived aluminium hydroxide at the site of injection. The condition is characterised by diffuse myalgias, arthralgia and fatigue. We describe a patient with histologically confirmed MMF whose presentation was atypical with left chest and upper limb pain beginning more than 10 years post vaccination. Treatment with steroids led to symptomatic improvement. Although rare, clinicians should consider MMF in cases of atypical myalgia.

    Background Neoplasms of the oral maxillofacial area are an interesting entity characterized by differences in nomenclature and classification at different centers. We report neoplastic histopathological diagnoses seen at the departments of oral maxillofacial surgery of Muhimbili and Mulago referral hospitals in Tanzania and Uganda respectively over a 10-year period. Methods We retrieved histopathological reports archived at the departments of oral maxillofacial surgery of Muhimbili and Mulago referral hospitals in Tanzania and Uganda respectively over a 10-year period from June 1989–July 1999. Results In the period between June 1989 and July 1999, 565 and 1298 neoplastic oro-facial cases were retrieved of which 284 (50.53%) and 967 (74.54%) were malignant neoplasms at Muhimbili and Mulago hospitals respectively. Overall 67.28% of the diagnoses recorded were malignant with Kaposi's sarcoma (21.98%), Burkiits lymphoma (20.45%), and squamous cell carcinoma (15.22%) dominating that group while ameloblastoma (9.23%), fibromas (7.3%) and pleomorphic adenoma (4.95%) dominated the benign group. The high frequency of malignancies could be due to inclusion criteria and the clinical practice of selective histopathology investigation. However, it may also be due to higher chances of referrals in case of malignancies. Conclusion There is need to reexamine the slides in these two centers in order to bring them in line with the most recent WHO classification so as to allow for comparison with reports from else where.

    Aim To report a 10-year follow-up of patients suffering from severe dry eye syndrome (DES) initially treated with topical ciclosporin A (tCSA) for 6 months. Methods The charts of 26 patients with severe DES related to keratoconjunctivitis sicca (KCS) and followed for a minimum 10-year follow-up were retrospectively reviewed. All of them were treated initially with tCSA for 6 months. The Schirmer I test, fluorescein and lissamine green staining scores and tear film break-up time (TBUT) were recorded to assess clinical symptoms before, during and after treatment. The subjective signs were evaluated with the ocular surface disease index (OSDI) questionnaire. Prolongation and reintroduction of tCSA after the initial treatment and combined treatments were also noted. Results Overall the median (IQR) duration of tCSA treatment was 23 (7–51) months after a prolonged induction treatment lasting 20 (8–41) months during the 10-year follow-up. For symptoms, a statistically significant difference in the OSDI between baseline and the end of the 10-year follow-up was not found (p=0.67). We noted a statistically significant improvement in all clinical signs after the initial treatment period, still present at the end of follow-up. Only 6.5% of the patients needed reintroduction of tCSA after their prolonged induction treatment. Conclusions The improvement observed after an initial tCSA treatment was sustained after a long-term follow-up with few cases requiring additional tCSA treatment. A prolonged induction treatment to decrease initial inflammatory local signs is a promising option in KCS. PMID:26823393

    The Marine Metadata Interoperability project (http://marinemetadata.org) held its public opening at AGU's 2004 Fall Meeting. For 10 years since that debut, the MMI guidance and vocabulary sites have served over 100,000 visitors, with 525 community members and continuous Steering Committee leadership. Originally funded by the National Science Foundation, over the years multiple organizations have supported the MMI mission: "Our goal is to support collaborative research in the marine science domain, by simplifying the incredibly complex world of metadata into specific, straightforward guidance. MMI encourages scientists and data managers at all levels to apply good metadata practices from the start of a project, by providing the best guidance and resources for data management, and developing advanced metadata tools and services needed by the community." Now hosted by the Harte Research Institute at Texas A&M University at Corpus Christi, MMI continues to provide guidance and services to the community, and is planning for marine science and technology needs for the next 10 years. In this presentation we will highlight our major accomplishments, describe our recent achievements and imminent goals, and propose a vision for improving marine data interoperability for the next 10 years, including Ontology Registry and Repository (http://mmisw.org/orr) advancements and applications (http://mmisw.org/cfsn).

    Bttomland hardwood forests were planted on agricultural fields in Mississippi and Louisiana using either predominantly Quercus species (oaks) or Populus deltoides (eastern cottonwood). We assessed avian colonization of these reforested sites between 2 and 10 years after planting. Rapid vertical growth of cottonwoods (circa 2 - 3 m / yr) resulted in sites with forest structure that supported greater species richness of breeding birds, increased Shannon diversity indices, and supported greater territory densities than on sites planted with slower-growing oak species. Grassland birds (Spiza americana [Dickcissel], and Sturnella magna [Eastern Meadowlark]) were indicative of species breeding on oak-dominated reforestation # 10 years old. Agelaius phoeniceus (Red-winged Blackbird) and Colinus virginianus (Northern Bobwhite) characterized cottonwood reforestation # 4 years old, whereas 14 species of shrub-scrub birds (e.g., Passerina cyanea [Indigo Bunting]) and early-successional forest birds (e.g., Vireo gilvus [Warbling Vireo]) typified cottonwood reforestation 5 to 9 years after planting. Rates of daily nest survival did not differ between reforestation strategies. Nest parasitism increased markedly in older cottonwood stands, but was overwhelmed by predation as a cause of nest failure. Based on Partners in Flight prioritization scores and territory densities, the value of cottonwood reforestation for avian conservation was significantly greater than that of oak reforestation during their first 10 years. Because of benefits conferred on breeding birds, we recommend reforestation of bottomland hardwoods include a high proportion of fast-growing, early successional species such as cottonwood.

  17. Periodic local MP2 method employing orbital specific virtuals

    Usvyat, Denis; Maschio, Lorenzo; Schütz, Martin

    2015-09-01

    We introduce orbital specific virtuals (OSVs) to represent the truncated pair-specific virtual space in periodic local Møller-Plesset perturbation theory of second order (LMP2). The OSVs are constructed by diagonalization of the LMP2 amplitude matrices which correspond to diagonal Wannier-function (WF) pairs. Only a subset of these OSVs is adopted for the subsequent OSV-LMP2 calculation, namely, those with largest contribution to the diagonal pair correlation energy and with the accumulated value of these contributions reaching a certain accuracy. The virtual space for a general (non diagonal) pair is spanned by the union of the two OSV sets related to the individual WFs of the pair. In the periodic LMP2 method, the diagonal LMP2 amplitude matrices needed for the construction of the OSVs are calculated in the basis of projected atomic orbitals (PAOs), employing very large PAO domains. It turns out that the OSVs are excellent to describe short range correlation, yet less appropriate for long range van der Waals correlation. In order to compensate for this bias towards short range correlation, we augment the virtual space spanned by the OSVs by the most diffuse PAOs of the corresponding minimal PAO domain. The Fock and overlap matrices in OSV basis are constructed in the reciprocal space. The 4-index electron repulsion integrals are calculated by local density fitting and, for distant pairs, via multipole approximation. New procedures for determining the fit-domains and the distant-pair lists, leading to higher efficiency in the 4-index integral evaluation, have been implemented. Generally, and in contrast to our previous PAO based periodic LMP2 method, the OSV-LMP2 method does not require anymore great care in the specification of the individual domains (to get a balanced description when calculating energy differences) and is in that sense a black box procedure.

    IRIS data (the low degree ℓ≤ 3 helioseismology network) have been analysed for the study of p-mode parameters variability over the falling phase of the solar activity cycle 22 and the rising phase of the solar activity cycle 23. The IRIS duty cycle has been improved by the so-called ``repetitive music method'', a method of partial gap filling. We present in this paper an analysis of the dependence of p-mode frequencies and linewidths with frequency and with solar magnetic activity. We confirm also the periodicity of about 70 μHz of the high-frequency pseudo modes, with a much reduced visibility during the phase of higher activity.

    2016-08-01

    Research and practice in the area of motor speech disorders (MSDs) will change in the next 10 years, most likely in evolutionary rather revolutionary ways. We are likely to see an increase in the understanding of the underpinnings of MSDs and refinements in assessment and diagnosis. Management approaches probably will be refined, as will how outcomes are measured. The evidence base for treatment efficacy will grow. Technology and changes in the health care system will have strong and overarching, but not easily predicted, influences. This article provides a broad overview of these and related issues, with some cautious predictions.

    We describe a 10-year-old girl who presented with bizarre purpura. Both congenital and autoimmune hemorrhagic disorders were excluded based on her past medical history and physical and laboratory findings. Child abuse was also ruled out as purpura continued to develop after child-family separation. Histologic examination of the skin lesions revealed disruption of collagen fiber bundles. This finding indicated application of external force, leading to a definitive diagnosis of factitious purpura. Although it is very rare in school-age children, the diagnosis of factitious purpura should be included in the differential diagnosis of purpura in children. Histologic analysis of skin biopsies may aid in establishing the diagnosis.

Modern andrology in China had a late start, with the Chinese Andrology Association founded in 1995. Within last decade, andrology in China has grown rapidly. In this review article, we summarized the progress of andrology in last 10 years and outlined the current status of Chinese andrology with a special focus on progress in male erectile dysfunction, prostate diseases, male infertility and male hormonal contraception.

    AIM: To evaluate the predictors of 10-year survival of patients with hepatitis C recurrence. METHODS: Data from 358 patients transplanted between 1989 and 2010 in two Italian transplant centers and with evidence of hepatitis C recurrence were analyzed. A χ2, Fisher’s exact test and Kruskal Wallis’ test were used for categorical and continuous variables, respectively. Survival analysis was performed at 10 years after transplant using the Kaplan-Meier method, and a log-rank test was used to compare groups. A P level less than 0.05 was considered significant for all tests. Multivariate analysis of the predictive role of different variables on 10-year survival was performed by a stepwise Cox logistic regression. RESULTS: The ten-year survival of the entire population was 61.2%. Five groups of patients were identified according to the virological response or lack of a response to antiviral treatment and, among those who were not treated, according to the clinical status (mild hepatitis C recurrence, “too sick to be treated” and patients with comorbidities contraindicating the treatment). While the 10-year survival of treated and untreated patients was not different (59.1% vs 64.7%, P = 0.192), patients with a sustained virological response had a higher 10-year survival rate than both the “non-responders” (84.7% vs 39.8%, P < 0.0001) and too sick to be treated (84.7% vs 0%, P < 0.0001). Sustained virological responders had a survival rate comparable to patients untreated with mild recurrence (84.7% vs 89.3%). A sustained virological response and young donor age were independent predictors of 10-year survival. CONCLUSION: Sustained virological response significantly increased long-term survival. Awaiting the interferon-free regimen global availability, antiviral treatment might be questionable in selected subjects with mild hepatitis C recurrence. PMID:25852276

    Expanding upon Pimbblet's 2011 analysis of career h-indices for members of the Astronomical Society of Australia, we provide additional citation metrics which are geared to quantifying the current performance of all professional astronomers in Australia. We have trawled the staff web-pages of Australian Universities, Observatories and Research Organisations hosting professional astronomers, and identified 384 PhD-qualified, research-active, astronomers in the nation. 132 of these are not members of the Astronomical Society of Australia. Using the SAO/NASA Astrophysics Data System, we provide the three following common metrics based on publications in the first decade of the 21st century (2001-2010): h-index, author-normalised citation count and lead-author citation count. We additionally present a somewhat more inclusive analysis, applicable for many early-career researchers, that is based on publications from 2006-2010. Histograms and percentiles, plus top-performer lists, are presented for each category. Finally, building on Hirsch's empirical equation, we find that the (10-year) h-index and (10-year) total citation count T can be approximated by the relation AS12011_IE1.gif for h>~5.

    Production of bacterial nanocellulose (BNC) is becoming increasingly popular owing to its environmentally friendly properties. Based on this benefit of BNC production, researchers have also begun to examine the capacity for cellulose production through microbial hosts. Indeed, several research groups have developed processes for BNC production, and many studies have been published to date, with the goal of developing methods for large-scale production. During BNC bioproduction, the culture medium represents approximately 30 % of the total cost. Therefore, one important and challenging aspect of the fermentation process is identification of a new cost-effective culture medium that can facilitate the production of high yields within short periods of time, thereby improving BNC production and permitting application of BNC in the biotechnological, medical, pharmaceutical, and food industries. In this review, we addressed different aspects of BNC production, including types of fermentation processes and culture media, with the aim of demonstrating the importance of these parameters.

    This article reviews my new optical fiber sensing (OFS) research activities in China for the last ten years at Chongqing University and University of Electronic Science and Technology of China, since I returned from UK in 1999. The research progress in long period fiber gratings (LPFGs), distributed fiber sensing systems and microfiber sensors is introduced. For LPFGs, the processing method with high-frequency CO2 laser pulses types of LPFGs fabricated and the related applications for both optical sensing and optical communication are described. For distributed fiber sensing systems, the fiber-optic polarization optical time domain reflectometer (POTDR), fiber-optic phase-sensitive optical time domain reflectometer (Φ-OTDR) and Brillouin optical time-domain analyzer (BOTDA) are developed, respectively. For microfiber sensors, we mainly focus on the knot resonator and its application for sensing of the refractive index and acceleration, etc.

    Bioabsorbable fixation devices have been used in our departments between November 1991 and November 2001 in orthognathic surgery. The aim of this retrospective study was to assess all complications experienced during this time period, when we have operated 163 patients who have undergone 329 orthognathic osteotomies fixated with bioresorbable devices. No postoperative intermaxillary fixation was used. Light guiding elastics were used for 5 to 7 weeks. Patients' acceptance was generally excellent and very few complications occurred during this follow-up of 10 years. The complications were minor and did not affect the end results of the operations. Minor complications occurred in 14 patients (8.6%). Only one patient (0.6%) had a postoperative infection with elevated infection parameters. The other minor complications consisted mainly of dehiscence of the wound and plate exposure together with granulation tissue in the operation field. The rest of the complications occurred in the beginning of our study, when large screw heads on top of the bone irritated the patient and had to be removed. Insufficient fixation resulted in open bite in three patients (1.8%) in the beginning of the trial use of new devices, which no longer are used. Based on our experience, bioresorbable devices are safe to be used in orthognathic procedures. However, there is a learning curve, as there is with all new methods introduced.

    The most popular numerical technique in rough surface scattering is the Method of Moments (MoM). Since the scattering patch size is finite, the edge current must be suppressed to obtain accurate scattering cross sections. Two standard ways to minimize the edge current are periodic boundary conditions and incident wave tapering. We compare the accuracy & computational requirements of these methods.

    The Resource Program is the Bonneville Power Administration's primary process for deciding how to meet future electricity resource needs, how much new resources to develop, which types of resources to acquire or option and how to go about acquiring them, and how much BPA will have to spend for these resources. Recognizing that BPA must make a long-term commitment to acquiring conservation effectively, the 1992 Resource Program outlines a 10-year plan. Draft 2 of the 1992 Resource Program provides a framework for discussing the funding levels proposed in the Programs in Perspective (PIP) process. Previous final resource programs have been released prior to the PIP process. This version of the Resource Program recognizes that the PIP discussions are an integral part of the resource decision-making process and, therefore, it will be finalized after PIP.

    Scurvy, or hypovitaminosis C, is an uncommon condition that exists today primarily within certain unique populations-particularly the elderly subjects, patients with neurodevelopmental disabilities or psychiatric illnesses, or others with unusual dietary habits. Vitamin C is an essential nutrient in the human body, and is important in synthesizing collagen factor whose faulty production is responsible for most of the clinical manifestations of scurvy. These clinical manifestations can include dystrophic or corkscrew hairs, gingival hyperplasia, and weakened blood vessel walls, causing bleeding in the skin, joints, and other organs. Although rare in the Unites States, the presence of scurvy should not be forgotten because of its presence among susceptible populations. Moreover, with its diagnosis, treatment and cure is one of the simplest in modern medicine. We report a case of scurvy in a 10-year-old autistic child.

    Early Class III malocclusion treatment may not have long-term stability due to mandibular growth. Although some features of this malocclusion point to a better prognosis, it is practically impossible for the orthodontist to foresee cases that require new intervention. Many patients need retreatment, whether compensatory or orthodontic-surgical. The present study reports the case of a Class III patient treated at the end of the mixed dentition with the use of a face mask followed by conventional fixed appliances. The case remains stable 10 years after treatment completion. It was presented to the Brazilian Board of Orthodontics and Dentofacial Orthopedics (BBO) as a requirement for the title of certified by the BBO. PMID:25715726

    Background: Dysembryoplastic neuroepithelial tumors (DNETs) are benign tumors characterized by a cortical location; they result in symptoms of drug-resistant partial seizures in children. The development of DNETs is poorly understood because most of them are resected immediately upon diagnosis without any observation period owing to the intractable seizures. Case Description: We report the first DNET case with the growth rate analyzed in the natural course of development for a period of 10 years. The patient was a right-handed man who was initially referred to another hospital with mild head injury when he was 8 years old. A tumor located in the right insular cortex was incidentally detected on magnetic resonance imaging (MRI) and followed-up with annual MRI for 10 years. Conclusion: In this case, the volume of the DNET increased in direct proportion to the length of time in its clinical course. The tumor doubling time was approximately 10 years. This case suggests DNET is a slow-growing but not stable tumor. PMID:28194304

    Purpose To report the outcomes of combined phacoemulsification and -deep sclerectomy (phaco-DS) from a single UK centre over a 10-year period. Methods Retrospective analysis of phaco-DS data extracted from an ongoing glaucoma surgery database within Calderdale and Huddersfield NHS Trust. Two hundred and ninety-six eyes of 282 patients were included. Data included patient demographics, pre- and postoperative intraocular pressure (IOP), use of mitomycin C (MMC), spacer device implantation, and follow-up details including surgical success rates. IOP success criteria were: (A) IOP <19 mm Hg and/or 20% decrease from baseline and (B) IOP <16 mm Hg and/or 30% drop from baseline. Results Mean follow-up was 63.5±35.3 months. MMC was applied in 145 eyes (49%). Kaplan–Meier success rates in all eyes for criteria A were 89.1% and 80% with glaucoma medications (qualified success) and 81.2% and 68.3% without medications (unqualified success) at 2 and 5 years, respectively. Qualified success for criteria B was 72.4 and 61.4% and unqualified rates were 67.2 and 55.2% for the same time periods. Repeated-measures ANOVA showed significantly lower IOP in the phaco-DS with MMC group up to 3 years postoperatively (P=0.002). Cox's proportional hazards for criteria B, however, showed no significant effect of MMC application in the long term (P=0.2). Increasing age and laser goniopuncture were positively associated with success, whereas the absence of spacer devices was negatively associated. At last follow-up, 20% of eyes were on glaucoma medications. Complication rates were low with hypotony rates of 0.68%. Conclusions This study confirms the long-term safety and efficacy of phaco-DS as a primary glaucoma procedure. PMID:26337945

  5. Clinical drug trials in general practice: a 10-year overview of protocols

    2013-01-01

    Background Drugs predominantly prescribed in general practice should ideally be tested in that setting; however, little is known about drug trials in general practice. Our aim was to describe drug trials in Norwegian general practice over the period of a decade. Methods The present work concerns a 10-year retrospective study of protocols submitted to the Norwegian national medicines agency (1998 to 2007) identifying all studies involving general practitioners (GPs) as clinical investigator(s). We analyzed the number of trials, drug company involvement, patients, participating doctors, payment, medications tested and main diagnostic criteria for inclusion. We also analyzed one trial in greater detail. Results Out of 2,054 clinical drug trials, 196 (9.5%) were undertaken in general practice; 93% were multinational, 96% were industry funded and 77% included patients both from general practice and specialist care. The trials were planned to be completed in the period 1998 to 2012. A total of 23,000 patients in Norway and 340,000 patients internationally were planned to be included in the 196 trials. A median of 5 GPs participated in each trial (range 1 to 402). Only 0.7% of 831 GP investigators had general practice university affiliations. Median payment for participating investigators was €1,900 (range €0 to 13,500) per patient completing the trial. A total of 30 pharmaceutical companies were involved. The drugs most commonly studied were antidiabetics (21%), obstructive airway disease medications (12%), agents acting on the renin-angiotensin system (10%), and lipid modifying agents (10%). One trial, presented in more detail, had several characteristics of a seeding or marketing trial. Conclusions Only one in four drug trials involving general practice were solely general practice trials and almost all were industry initiated without input from academic general practice. There was a large variation in the number of patients, participating doctors, and economic

    A 10-year review (1987-1996) of injuries sustained to the spine and spinal cord in rugby players with resultant paralysis has been undertaken. This article reviews that the incidence of serious rugby spine and spinal cord injuries in South Africa has increased over the 10-year period reviewed, despite stringent new rules instituted in an attempt to decrease the incidence of these injuries. The mechanisms of injury, as previously reported, remain the same as well as the phases of game responsible for injury of the tight scrum, tackle, rucks, and mauls. Two new observations are reported: the first is related to the occurrence of spinal cord concussion with transient paralysis, and the second is related to the increased incidence of osteoarthritis of the cervical spine in rugby players.

    2015-12-01

    The purpose of the present study was to test a relational spillover model of physical aggression whereby physical aggression affects marital outcomes due to its effects on how spouses ask for and provide support to one another. Newlywed couples (n = 172) reported levels of physical aggression over the past year and engaged in interactions designed to elicit social support; marital adjustment, and stability were assessed periodically over the first 10 years of marriage. Multilevel modeling revealed that negative support behavior mediated the relationship between physical aggression and 10-year marital adjustment levels whereas positive support behavior mediated the relationship between physical aggression and divorce status. These findings emphasize the need to look beyond conflict when explaining how aggression affects relationships and when working with couples with a history of physical aggression who are seeking to improve their relationships.

    This study examined (a) the role of avoidance coping in prospectively generating both chronic and acute life stressors and (b) the stress-generating role of avoidance coping as a prospective link to future depressive symptoms. Participants were 1,211 late-middle-aged individuals (500 women and 711 men) assessed 3 times over a 10-year period. As predicted, baseline avoidance coping was prospectively associated with both more chronic and more acute life stressors 4 years later. Furthermore, as predicted, these intervening life stressors linked baseline avoidance coping and depressive symptoms 10 years later, controlling for the influence of initial depressive symptoms. These findings broaden knowledge about the stress-generation process and elucidate a key mechanism through which avoidance coping is linked to depressive symptoms. PMID:16173853

Few outlets were able to accommodate and quickly share that amount of information as well as the Internet. To honor the 10-year anniversary of the launch of Terra, we would like to highlight the education and outreach efforts of the Terra mission on the Internet and its reach to the science attentive public. The Internet or web has been the primary way of delivering Terra content to different groups- from formal and informal education to general public outreach. Through the years, many different web-based projects have been developed, and they were of service to a growing population of the science attentive public. One of Terra’s original EPO activities was the Earth Observatory. It was initially dedicated to telling the remote sensing story of Terra, but quickly grew to include science and imagery from other sensors. The web site allowed for collaboration across NASA centers, universities and other organizations by exchanging and sharing of story ideas, news and images. The award winning Earth Observatory helped pave the way for the more recently funded development of the Climate Change website. With its specific focus on climate change studies, once again, Terra stories and images are shared with an even more specific audience base. During the last 10 years, Terra as a mission has captured the imagination of the public through its visually stunning and artistically arresting images. With its five instruments of complementary but unique capabilities, the mission gave the world not just pretty pictures, but scientific data-based images. The world was able to see from space everything from calving icebergs to volcanic eruption plumes and the eye of a

    The aims of the study were to evaluate the incidence of Helicobacter pylori and Helicobacter heilmannii in untreated Bulgarian children from 1996 to 2006, to analyse the performance of diagnostic tests, and to look at H. pylori density in specimens by culture. Antral specimens from children with chronic gastritis (n=513), peptic ulcers (n=54) and other diseases (n=91) were evaluated by direct Gram staining (DGS), in-house rapid urease test (RUT) and culture. The living environment and semi-quantitative H. pylori density were assessed in 188 and 328 children, respectively. H. pylori infection was found in children with ulcers (77.8 %), chronic gastritis (64.5 %) and other diseases (36.3 %). Half (51.4 %) of patients aged 1-5 years and 77.4 % of those aged 16-17 years were H. pylori-positive. Of all children, 328 (49.8 %) showed positive DGS, 184 (28 %) had a positive RUT, and 386 (58.7 %) were culture-positive. Unlike gastric mucus specimens, frozen biopsy specimens provided reliable diagnosis. H. heilmannii was observed in two (0.3 %) children. High H. pylori density (growth into all quadrants of plates) was found in 18 % of 328 children evaluated, involving 31 % of ulcer and 16.7 % of non-ulcer patients. H. pylori infection was more common in rural children with chronic gastritis (91.3 %) than in the remainder (66.7 %). In conclusion, H. pylori infection was common in symptomatic Bulgarian children. The infection prevalence was >77 % in patients aged 16-17 years, in children with a duodenal ulcer, and in rural patients. H. heilmannii infection was uncommon. The performance of the bacterial culture was good. The impact of H. pylori density on the clinical expression and eradication of the infection requires further evaluation. The results highlight the need for routine H. pylori diagnosis in rural children with chronic gastritis.

    Titan hosts the most chemically complex atmosphere in the solar system. The first encounter of the Cassini spacecraft with Titan was in October 2004 with a closest approach altitude of 1147km. Since then the Cassini has made measurements of the ionospheric species over multiple flybys and has provided a unique opportunity to study long term effects on Titan's ionosphere including solar activity cycle. It has been shown that solar extreme ultraviolet radiation is the main source of ion production and production rates are highly dependent on solar zenith angle. We use data from the ion and Neutral Mass Spectrometer (INMS) and the Radio and Plasma Wave Science-Langmuir probe (RPWS-LP) instruments onboard the Cassini spacecraft to investigate changes in the ion composition of the ionosphere. We compare the observations with the results of our ionospheric models. Data from 21 targeted Titan flybys are used, covering the declining phase of solar cycle 23 into the double peak of solar cycle 24. We show that the ion densities have in fact increased during the high solar activity, especially at altitudes near the ionospheric peak, and unlike Earth, the Titan's thermosphere is contracted during high solar activity. Charge neutrality is assumed near the peak of the ionosphere, however difference exists between INMS total ion densities and RPWS-LP electron densities and it becomes more noticeable at high solar activity. This may be for several reasons including enhanced negative ion densities and increased electron recombination rates. The model results agree reasonably well with the in-situ measurements for most ion species at low and high solar activity conditions although overproduction exists for some ions (e.g. HCNH+) and underproduction is seen for some heavier species such as C7H7+.

    Squamous cell carcinoma of the oral cavity a type of Oral Cancer in young patients is a very rare occurrence particularly during the first decade of life. Oral cancer is predominantly an aggressive neoplasm of middle-aged people where 96% of the patients are more than 40 years of age and it occurs mainly due to the excessive consumption of tobacco and alcohol. In South-East Asia it has a higher rate of occurrence than the rest of the world, partly due to increased consumption of chewing tobacco and various harmful spices, areca nuts and betel quids. These rare varieties of aggressive neoplasm commonly affect tongue and lip. This report describes a case of squamous cell carcinoma in a 10 year old boy who had an exophytic type of granulomatous lesion with some indurated borders which diffusely involved the left side of the hard palate, alveolar mucosa, left maxillary antrum and aggressively emerged within the left orbit by engulfing the left inferior rectus muscle. The purpose of this case report is to provide information that younger group can suffer from oral squamous cell carcinoma though it is very rare and this younger group would appear to have a biologically more aggressive tumor and they require more complex treatment. The role of more aggressive initial therapy must be considered.

    The dissociative recombination of has been an intriguing problem for more than half a century. The early experiments on during the first 20 years were carried out without mass analysis in decaying plasma afterglows, and thus the measured rates pertained to an uncontrolled mixture of and impurity ions. When mass analysis was used, the rate coefficient was determined to be an uneventful value of about 10−7 cm3 s−1, a very common rate coefficient for many molecular ions. But this was not the end of the story, not even the beginning of the end; it marked only the end of the beginning. The story I will tell in this article started about 10 years ago, when the dissociative recombination of was approaching its deepest crisis. Today, owing to an extensive experimental and theoretical effort, the state of affairs has reached a historically unique level of harmony, although there still remains many things to sort out.

    Background Heart transplant-related stressors and coping are related to poor outcomes early after transplant. The purposes of our study were to (1) identify the most frequent and bothersome stressors and most used and effective coping strategies, and (2) compare the most frequent and bothersome stresses and most used and effective coping styles between patients at 5 and 10 years after heart transplantation. We also examined differences in coping styles by patient characteristics, and factors associated with frequency and intensity of stress at both 5 and 10 years after heart transplantation. Methods This report is a secondary analysis of data from a prospective, multi-site study of quality of life outcomes. Data are from 199 and 98 patients at 5 and 10 years after transplant, respectively. Patients completed the Heart Transplant Stressor Scale and Jalowiec Coping Scale. Statistical analyses included frequencies, measures of central tendency, t-tests, Chi-square and generalized linear models. Results At 5 and 10 years after heart transplantation, the most bothersome stressors were regarding work, school, and financial issues. Patients who were 10 years post transplant reported less stress, similar stress intensity, and less use and perceived effectiveness of negative coping than patients who were 5 years post transplant. Long-term after transplant, demographic characteristics, psychological problems, negative coping, and clinical factors were related to stress frequency and/or intensity. Conclusions Heart transplant-related stress occurs long-term after surgery. Types of transplant-related stress and factors related to stress confirm the importance of ongoing psychological and clinical support after heart transplantation. PMID:23498164

    2014-01-01

    Worldwide, fishery managers strive to maintain fish stocks at or above levels that produce maximum sustainable yields, and to rebuild overexploited stocks that can no longer support such yields. In the United States, rebuilding overexploited stocks is a contentious issue, where most stocks are mandated to rebuild in as short a time as possible, and in a time period not to exceed 10 years. Opponents of such mandates and related guidance argue that rebuilding requirements are arbitrary, and create discontinuities in the time and fishing effort allowed for stocks to rebuild due to differences in productivity. Proponents, however, highlight how these mandates and guidance were needed to curtail the continued overexploitation of these stocks by setting firm deadlines on rebuilding. Here we evaluate the statements made by opponents and proponents of the 10-year rebuilding mandate and related guidance to determine whether such points are technically accurate using a simple population dynamics model and a database of U.S. fish stocks to parameterize the model. We also offer solutions to many of the issues surrounding this mandate and its implementation by recommending some fishing mortality based frameworks, which meet the intent of the 10-year rebuilding requirement while also providing more flexibility.

    The advent of click chemistry has had a profound influence on almost all branches of chemical science. This is particularly true of radiochemistry and the synthesis of agents for positron emission tomography (PET), single photon emission computed tomography (SPECT), and targeted radiotherapy. The selectivity, ease, rapidity, and modularity of click ligations make them nearly ideally suited for the construction of radiotracers, a process that often involves working with biomolecules in aqueous conditions with inexorably decaying radioisotopes. In the following pages, our goal is to provide a broad overview of the first 10 years of research at the intersection of click chemistry and radiochemistry. The discussion will focus on four areas that we believe underscore the critical advantages provided by click chemistry: (i) the use of prosthetic groups for radiolabeling reactions, (ii) the creation of coordination scaffolds for radiometals, (iii) the site-specific radiolabeling of proteins and peptides, and (iv) the development of strategies for in vivo pretargeting. Particular emphasis will be placed on the four most prevalent click reactions-the Cu-catalyzed azide-alkyne cycloaddition (CuAAC), the strain-promoted azide-alkyne cycloaddition (SPAAC), the inverse electron demand Diels-Alder reaction (IEDDA), and the Staudinger ligation-although less well-known click ligations will be discussed as well. Ultimately, it is our hope that this review will not only serve to educate readers but will also act as a springboard, inspiring synthetic chemists and radiochemists alike to harness click chemistry in even more innovative and ambitious ways as we embark upon the second decade of this fruitful collaboration.

    Although the predictive factors of postoperative mortality after coronary artery surgery are well known, those predictive of long-term survival have received less attention. This study reviews the outcome of a group of 480 patients between 50 and 65 years of age, operated between 1984 and 1986. The patients were classified in two groups according to the presence or absence of internal mammary artery bypass grafts: Group I (304 patients with saphenous vein bypass grafts alone) and group II (176 patients with an internal mammary artery +/- saphenous vein bypass grafts). The long-term results were assessed according to 3 criteria: isolated cardiac mortality: cardiac mortality associated with a repeat revascularisation procedure and cardiac mortality associated with reoperation or recurrence of angina. Cardiac survival at 10 years was significantly better after internal mammary-LAD bypass: 91.4% (CI 87.1-95.1) than after saphenous vein bypass grafting alone: 79.6% (CI 74.8-84.4) (p = 0.012). Univariate analysis identified the following poor predictive factors: three vessel disease (p = 0.03), preoperative left ventricular dysfunction with an ejection fraction inferior to 45% (p = 0.0001), incomplete revascularisation (p = 0.0003), use of venous bypass graft alone (p < 0.014) and perioperative infarction (p = 0.0254). For each criterion of survival (cardiac isolated or associated with a new revascularisation and/or recurrence of angina), multivariate analysis identified three independent predictive factors of long-term extramortality: not using internal mammary artery-LAD bypass graft, incomplete revascularisation and preoperative hypertension. This study confirms the beneficial effects of internal mammary-LAD artery grafting on long-term survival after coronary artery surgery, and also demonstrates the prejudicial effects of hypertension.

We report the characteristics of 38 cases of mixed gender and nationality ranging in age between 13 and 18 years who have been apprehended by HMCE due to the illegal importation of drugs. Highlighted is an increasing trend in UK national male and female adolescents being apprehended for drug trafficking. Of particular note is the observation that more young adolescent females were apprehended importing large consignments of Class A substances than their male counterparts.

    A comparative retrospective study of 48 open heel spur surgeries and 20 endoscopic plantar fasciotomies was conducted involving 59 patients over a 10-year period. There was a significant reduction in heel pain at the time of follow-up (average, 3 years) for both groups. Overall, 85% of procedures were associated with patient satisfaction with the results, and patients said that they would recommend heel spur surgery for relief of severe heel pain in 94% of cases. Factors influencing the postoperative outcome, such as duration of preoperative symptoms, extent of conservative care, and obesity, are discussed.

    In this study we present and describe a satellite-derived precipitation climatology over northern South America using a passive microwave technique, the Goddard Profiling Algorithm. A period of data slightly longer than 10 years is examined. The climatologies take the form of the mean estimated (adjusted) rainfall for a 10-year (+) period, with sub-divisions by month and meteorological season. For the six-year period 1992-1997, when two satellites were in operation, diurnal variability (to the extent it is discerned by four unequally spaced observations) is presented. We find an alternating pattern of morning and maxima stretching from the northeast (Atlantic coast) clear across the continent to the Pacific. The effects of topography, coastlines and geography (river valleys) on the rainfall patterns are clear. Interannual variability is examined by computing the deviations of yearly and warm season (DJF) rainfall from their respective long-term means. Interannual variability of the diurnal nature of the rainfall is presented, and the strong El Nino event of 1997-1998 is discussed.

    Introduction. Osteogenesis imperfecta (OI) is a very rare disease compared to other afflictions, running the risk of social isolation for children and their parents, due to the problems specific to the disease. All the social, psychological and physical disadvantages must be removed or at least mitigated, all within the society’s limited resources. In Romania, this situation has led in the last couple of years to the selection of a number of extremely severe cases, which could not be solved by orthopedic and classic surgical treatment methods. These patients exhibit gracile long bones, which are distorted, often with cystic degeneration at the level of the extremities, pseudarthroses, limb length discrepancies, most of them being unable to walk, being condemned to sitting in a wheelchair. Aim. This paper deals with the experience of the Orthopedics Department of "Maria Sklodowska Curie" Clinical Emergency Hospital for Children, in Bucharest, in the field of surgical treatment for moderate and severe forms of OI, within the time frame of May 2002-May 2012. For the first time in Romania, on May 20, 2002, the team led by Professor Gh. Burnei, MD, has implanted telescopic rods in the femur and tibia of a patient with OI. One of the most important themes, of great interest in the orthopedic surgery, is the osteoarticular regularization and reconstruction in severe forms of OI, which should allow the patients to stand and walk. These cases are a challenge for the surgeon, who is in the position of applying new, complex procedures, or perfecting, modifying and adapting techniques that have already been established. The aim of the surgical treatment is the increase of the quality of life of these children and adolescents and of their social integration. Methods and results. In the above-mentioned period, from the OI patients who are in the evidence of our clinic, 32 were operated on, totaling 81 surgeries. Out of these, 28 patients, aged 2-27 years, have benefited from

    Growing evidence suggests that anthropogenic litter, particularly plastic, represents a highly pervasive and persistent threat to global marine ecosystems. Multinational research is progressing to characterise its sources, distribution and abundance so that interventions aimed at reducing future inputs and clearing extant litter can be developed. Citizen science projects, whereby members of the public gather information, offer a low-cost method of collecting large volumes of data with considerable temporal and spatial coverage. Furthermore, such projects raise awareness of environmental issues and can lead to positive changes in behaviours and attitudes. We present data collected over a decade (2005-2014 inclusive) by Marine Conservation Society (MCS) volunteers during beach litter surveys carried along the British coastline, with the aim of increasing knowledge on the composition, spatial distribution and temporal trends of coastal debris. Unlike many citizen science projects, the MCS beach litter survey programme gathers information on the number of volunteers, duration of surveys and distances covered. This comprehensive information provides an opportunity to standardise data for variation in sampling effort among surveys, enhancing the value of outputs and robustness of findings. We found that plastic is the main constituent of anthropogenic litter on British beaches and the majority of traceable items originate from land-based sources, such as public littering. We identify the coast of the Western English Channel and Celtic Sea as experiencing the highest relative litter levels. Increasing trends over the 10-year time period were detected for a number of individual item categories, yet no statistically significant change in total (effort-corrected) litter was detected. We discuss the limitations of the dataset and make recommendations for future work. The study demonstrates the value of citizen science data in providing insights that would otherwise not be

    The transcorrelated (TC) method is one of the promising wave-function-based approaches for the first-principles electronic structure calculations. In this method, the many-body wave function is approximated as the Jastrow-Slater type and one-electron orbitals in the Slater determinant are optimized with a one-body self-consistent-field equation such as that in the Hartree-Fock (HF) method. Although the TC method has yielded good results for both molecules and solids, its computational cost in solid-state calculations, being of order O(N_k^3N_b^3) with Nk and Nb the respective numbers of k-points and bands, has for some years hindered its wide application in condensed matter physics. Although an efficient algorithm was proposed for a Gaussian basis set, that algorithm is not applicable to a plane-wave basis that is suited to and widely used in solid-state calculations. In this paper, we present a new efficient algorithm of the TC method for the plane-wave basis or an arbitrary basis function set expanded in terms of plane waves, with which the computational cost of the TC method scales as O(N_k^2N_b^2). This is the same as that of the HF method. We applied the TC method with the new algorithm to obtain converged band structure and cell parameters of some semiconductors.

    Background Few studies in low-income settings analyse linear growth trajectories from foetal life to pre-adolescence. The aim of this study is to describe linear growth and stunting from birth to 10 years in rural Bangladesh and to analyse whether maternal and environmental determinants at conception are associated with linear growth throughout childhood and stunting at 10 years. Methods and Findings Pregnant women participating in the MINIMat trial were identified in early pregnancy and a birth cohort (n = 1054) was followed with 19 growth measurements from birth to 10 years. Analyses of baseline predictors and mean height-for-age Z-scores (HAZ) over time were modelled using GLMM. Logistic regression analysis was used to investigate the associations between baseline predictors and stunting (HAZ<-2) at 10 years. HAZ decreased to 2 years, followed by an increase up to 10 years, while the average height-for-age difference in cm (HAD) to the WHO reference median continued to increase up to 10 years. Prevalence of stunting was highest at 2 years (50%) decreasing to 29% at 10 years. Maternal height, maternal educational level and season of conception were all independent predictors of HAZ from birth to pre-adolescence (p<0.001) and stunting at 10 years. The highest probability to be stunted at 10 years was for children born by short mothers (<147.5 cm) (ORadj 2.93, 95% CI: 2.06–4.20), mothers with no education (ORadj 1.74, 95% CI 1.17–2.81) or those conceived in the pre-monsoon season (ORadj 1.94, 95% CI 1.37–2.77). Conclusions Height growth trajectories and prevalence of stunting in pre-adolescence showed strong intergenerational associations, social differentials, and environmental influence from foetal life. Targeting women before and during pregnancy is needed for the prevention of impaired child growth. PMID:26934484

    The goal is to construct a symplectic evolution map for a large section of an accelerator, say a full turn of a large ring or a long wiggler. We start with an accurate tracking algorithm for single particles, which is allowed to be slightly non-symplectic. By tracking many particles for a distance S one acquires sufficient data to construct the mixed-variable generator of a symplectic map for evolution over S, given in terms of interpolatory functions. Two ways to find the generator are considered: (1) Find its gradient from tracking data, then the generator itself as a line integral. (2) Compute the action integral on many orbits. A test of method (1) has been made in a difficult example: a full turn map for an electron ring with strong nonlinearity near the dynamic aperture. The method succeeds at fairly large amplitudes, but there are technical difficulties near the dynamic aperture due to oddly shaped interpolation domains. For a generally applicable algorithm we propose method (2), realized with meshless interpolation methods.

    A total of 15,662 clinical samples were analysed for enterovirus (EV) isolation in cell cultures during a 10-year period (1988-97). Furthermore, 210 isolates of EV obtained in primary laboratories within Spain from patients with meningitis were characterized. The total number of EV typed was 758, including 727 non-polio EV and 31 Sabin-like (SL) polioviruses. Twenty-eight EV serotypes were represented. Echoviruses comprised 90% (653/727) of fully typed non-polio EV. The four most prevalent serotypes were echovirus 30, echovirus 9, echovirus 6 and echovirus 4. Echovirus 30 was the main serotype associated with meningitis. Echovirus 9 was the aetiological agent in 20 outbreaks of meningitis while the occurrence of echovirus 6 was localized in 1 year (1997). Coxsackieviruses A and B occurred in 3 and 7% of the non-polio EV respectively. Coxsackievirus B5 presented the relative greater abundance. This paper examines the epidemiology of EV in Spain to serotype level over a 10-year period with special attention to non-polio EV associated with meningitis. PMID:10982074

    Objectives: To describe the characteristics and prognostic factors of 28 patients with Fournier’s Gangrene (FG) referred to our medical center at Southeastern Iran. Methods: This was a cross-sectional study including 28 cases of FG that were operated in Surgery department of Zahedan University of Medical Sciences during a 10-year period from April 2002 to March 2012. The study analyzed 9 parameters including the body temperature, heart rate, respiratory rate, hematocrit, white blood count (WBC), and serum levels of sodium, potassium, creatininee (twice for 2 for acute renal failure), and bicarbonate for Fournier Gangrene Severity Index (FGSI) score. The aspects taken into account were age, gender, predisposing factors, duration of symptoms, hospitalization period, and number of debridements, disease outcome and the FGSI. Results: All patients were males, aged from 26 to 68 years, with mean age 44.6 ±8.49 years. Statistically significant differences in age (p<0.001), duration of symptoms (p=0.001), number of debridements (p=0.006), hospitalization duration (p<0.001) and FGSI (p<0.001) were found between surviving and dead patients. The mortality rate was 35.7%, and the most common presentation was perianal/scrotal pain (78.6%). Perianal and primary scrotal abscesses were most common causes of FG and were found in 57.14% and 21.42% of patients respectively. The most prevalent predisposing factor was diabetes mellitus in 12 (42.85%) patients. With respect to laboratory findings, statistically significant differences in WBC (p=0.002), creatinine (p<0.001), albumin (p<0.001), calcium (p<0.001) and serum sodium (p=0.035) were found between the surviving and dead patients. Conclusion: Serious outcome of FG was associated with old age, delayed diagnosis and treatment, inadequate surgical debridement, shorter hospitalization and higher FGSI scores. In addition higher WBC, higher creatininee and serum sodium and lower albumin and calcium levels implicated worse prognosis

    AIM To evaluate the relationship between the state of transplanted liver graft and the recipient quality of life (QOL) of histologically proven lesions in a 10-year post liver transplantation (LT) cohort of patients. METHODS Seventy-two recipients with a functional first graft at 10 years post-LT underwent liver biopsy and completed a QOL questionnaire. Logistic regression analysis was used to explore associations between histological, clinical and QOL criteria. RESULTS Ten years after LT, fibrosis was detected in 53% of patients, and affected the general health perception, while ductopenia, present in 36%, affected the well-being (P = 0.05). Hepatic steatosis (HS) was present in 33% of patients and was associated with the worst QOL score on multiple domains. When compared to patients without HS, patients with HS had significantly higher incidence of fibrosis (P = 0.03), hepatitis C virus (HCV) infection (P = 0.007), and more patients had retired from their job (P = 0.03). Recurrent or de novo HCV-associated fibrosis and patient retirement as objective variables, and abdominal pain or discomfort and joint aches or pains as subjective variables, emerged as independent determinants of HS. CONCLUSION Long-term liver graft lesions, mainly HS presumably as a surrogate marker of HCV infection, may have a substantial impact on QOL 10 years after LT. PMID:28058221

METHODS This study with convenience sample of 231 schoolchildren aged 9-10 years enrolled in public and private schools in Vitória, ES, Southeastern Brazil, in 2010-2011. Anthropometric and hemodynamic data, blood pressure, and pulse wave velocity in the carotid-femoral segment were obtained. Data on current and previous health conditions were obtained by questionnaire and notes on the child’s health card. Multiple linear regression was applied to identify the partial and total contribution of the factors in determining the pulse wave velocity values. RESULTS Among the students, 50.2% were female and 55.4% were 10 years old. Among those classified in the last tertile of pulse wave velocity, 60.0% were overweight, with higher mean blood pressure, waist circumference, and waist-to-height ratio. Birth weight was not associated with pulse wave velocity. After multiple linear regression analysis, body mass index (BMI) and diastolic blood pressure remained in the model. CONCLUSIONS BMI was the most important factor in determining arterial stiffness in children aged 9-10 years. PMID:25902563

    OBJECTIVES—To determine the incidence of neonatal meningitis in England and Wales.
DESIGN—A national postal survey using the British Paediatric Surveillance Unit (BPSU) card scheme supplemented by information from other sources.
SETTING—England and Wales 1996-1997.
SUBJECTS—A total of 274 babies less than 28 days of age who were treated for meningitis.
RESULTS—The incidence of neonatal meningitis in England and Wales has not changed since our previous study in 1985-1987. However, the acute phase mortality has fallen from 19.8% in 1985-1987 to 6.6% in this study. Group B streptococci (42%) and Escherichia coli (16%) remain the most common infecting microorganisms. Eight of 69 (12%) babies with group B streptococci and 4/26 (15%) with E coli died. Antibiotic regimens based on the third generation cephalosporins, notably cefotaxime, were most commonly used (84%). The BPSU scheme identified 72% of cases during the study period. Most cases of viral meningitis were not reported through the BPSU. Less than a third of samples from aseptic meningitis were examined for viruses; 56% of these were positive.
CONCLUSIONS—Although the incidence of neonatal meningitis remains unchanged, mortality from this infection has fallen significantly. If this improvement is maintained as reflected in the level of sequelae at 5 years of age, then the fear surrounding meningitis during the neonatal period will have been dramatically reduced.

    Purpose: To evaluate the long-term impact of locoregional breast radiotherapy (RT) on pulmonary function tests (PFTs). Methods and Materials: This study included 75 women who underwent postoperative locoregional breast RT. PFTs were performed before RT and 3, 6, and 12 months and 8 to 10 years after RT. By use of univariate and multivariate analyses, the impact of treatment- and patient-related factors on late changes in PFTs was evaluated. Results: During the first year after RT, all PFTs significantly worsened at 3 to 6 months after RT (p < 0.05). At 12 months, forced vital capacity (FVC), vital capacity (VC), and forced expiratory volume in 1 second (FEV{sub 1}) recovered almost to baseline values, whereas total lung capacity (TLC) and diffusion capacity of carbon monoxide (DL{sub CO}) recovered only slightly and were still found to be decreased compared with baseline (p < 0.05). At 8 to 10 years after RT, mean reductions in FEV{sub 1} of 4% (p = 0.03) and in VC, DL{sub CO}, and TLC of 5%, 9%, and 11% (all p < 0.0001), respectively, were observed compared with pre-RT values. On multivariate analysis, tamoxifen use negatively affected TLC at 8 to 10 years after RT (p = 0.033), whereas right-sided irradiation was associated with a late reduction in FEV{sub 1} (p = 0.027). For FEV{sub 1} and DL{sub CO}, an early decrease was predictive for a late decrease (p = 0.003 and p = 0.0009, respectively). Conclusions: The time course of PFT changes after locoregional RT for breast cancer follows a biphasic pattern. An early reduction in PFTs at 3 to 6 months with a partial recovery at 12 months after RT is followed by a late, more important PFT reduction up to 8 to 10 years after RT. Tamoxifen use may have an impact on this late decline in PFTs.

    Little information is available concerning early specialization and competitive success in judo across the early training years. Thus, the present objective was to verify the stability of individual competitive performance of a state-level championship for judo athletes who had been previously successful. For this, 406 athletes from six age groups (9 to 20+ years old) of each sex were followed for 10 years. Using recorded data from the São Paulo State Judo Federation beginning in 1999, the scores and standings for these judo players were analyzed. The proportion of medal winners during this period was not constant, differing from the grand mean in all groups of both 204 males and 202 females. At the end of this period, only 7% of the male and 5% of the female athletes had maintained their competitive levels. Successful competitive performance in early judo competition was not associated with success later in adulthood.

    Background The outcome of first episode schizophrenia has several determinants. Socioecological factors, particularly living conditions, migration, community and culture, not only affect the level of risk but also the outcome. Mega cities around the world show a unique socioecological condition that has several challenges for mental health. The present study reports on the long-term status of patients with schizophrenia in such a mega city: Mumbai, India. Aim This study aims to reveal the long-term outcome of patients suffering from schizophrenia with special reference to clinical symptoms and social functioning. Methods The cohort for this study was drawn from a 10-year follow-up of first episode schizophrenia. Patients having completed 10 years of consistent treatment after first hospitalisation were assessed on psychopathological and recovery criteria. Clinical as well as social parameters of recovery were evaluated. Descriptive statistics with 95% confidence intervals are provided. Results Of 200 patients recruited at the beginning of this study, 122 patients (61%) were present in the city of Mumbai at the end of 10-year follow-up study period. Among 122 available patients, 101 patients (50.5%) were included in the assessment at the end of 10-year follow-up study period, 6 patients (3.0%) were excluded from the study due to changed diagnosis, and 15 patients (7.5%) were excluded due to admission into long-term care facilities. This indicates that 107 out of 122 available patients (87.7%) were living in the community with their families. Out of 101 (50.5%) patients assessed at the end of 10 years, 61 patients (30.5%) showed improved recovery on the Clinical Global Impression Scale, 40 patients (20%) revealed no improvement in the recovery, 43 patients (72.9%) were able to live independently, and 24 patients (40%) were able to find employment. Conclusion With 10 years of treatment, the recovery rate among schizophrenia patients in Mumbai was 30.5%. Among the

    Narrowband filter (3.6-micron wavelength, 0.08-micron bandwidth) observations of the infrared flux of Venus are reported. The observations over the period from 1982 through 1984 covered a range of phase angle from 27 to 94 degrees. Normalized values of flux at the Venus-earth distance of 1 AU were (4.0-5.4) x 10 to the -17th watt per square centimeter per inverse centimeter, and the phase angle dependence of the data is rather weak. Furthermore, when the evening terminator of Venus was seen, lower values of flux were obtained, in contrast with higher values at the morning terminator. The phase angle dependence is quite different from that of Martonchik and Beer (1975), the difference possibly suggesting an intrinsic time variation of haze particles over ten years in the upper haze layer of the Venus cloudcover.

    2016-01-01

    Anorectal malformation (ARM) is one of the most common congenital anomaly that requires emergency surgery in the neonatal period. ARMs are frequently associated with other life threatening congenital anomalies. Commonly associated anomalies are genito-urinary, cardiovascular, gastro-intestinal, skeletal and spinal. Alimentary tract anomalies are frequently masked by the intestinal obstruction produced by the anorectal atresia. This retrospective study was carried out to find out the incidence of associated alimentary tract atresias with ARM. In our series, out of 785 cases of high ARM, 14 cases had associated esophageal atresia (1.8%), followed by 7 cases of duodenal atresia (0.89%), and followed by pyloric atresia, jejuno-ileal atresia and colonic atresia.

    Purpose: The purpose of this study is the development of reference pediatric phantoms for 5- and 10-year-old children to be used for the calculation of organ and tissue equivalent doses in radiation protection. Methods: The study proposes a method for developing anatomically highly sophisticated pediatric phantoms without using medical images. The 5- and 10-year-old male and female phantoms presented here were developed using 3D modeling software applied to anatomical information taken from atlases and textbooks. The method uses polygon mesh surfaces to model body contours, the shape of organs as well as their positions, and orientations in the human body. Organ and tissue masses comply with the corresponding data given by the International Commission on Radiological Protection (ICRP) for the 5- and 10-year-old reference children. Bones were segmented into cortical bone, spongiosa, medullary marrow, and cartilage to allow for the use of micro computer tomographic ({mu}CT) images of trabecular bone for skeletal dosimetry. Results: The four phantoms, a male and a female for each age, and their organs are presented in 3D images and their organ and tissue masses in tables which show the compliance of the ICRP reference values. Dosimetric data, calculated for the reference pediatric phantoms by Monte Carlo methods were compared with corresponding data from adult mesh phantoms and pediatric stylized phantoms. The comparisons show reasonable agreement if the anatomical differences between the phantoms are properly taken into account. Conclusions: Pediatric phantoms were developed without using medical images of patients or volunteers for the first time. The models are reference phantoms, suitable for regulatory dosimetry, however, the 3D modeling method can also be applied to medical images to develop patient-specific phantoms.

    Context: Sociocultural factors complement psychopathological factors that result in deliberate self-harm (DSH). A study of change in these factors over time is essential for preventive action. Aims: To identify factors influencing DSH, which have shown significant variation over a period of 10 years. Settings and Design: Two hospital-based cross-sectional analytic types of observational studies were performed at two different times at an interval of 10 years. Materials and Methods: Sociodemographic profile, factors related to DSH, stressful life events, and psychiatric disorders were assessed in two groups of patients drawn from the same tertiary care hospital, 100 consecutive patients in 2002 and 117 in 2012. The observations were compared to identify factors that have undergone significant change. Statistical Analysis: Descriptive statistics along with Chi-square test was used in this study. Results: A significant decrease in the overall number of married subjects (60% vs. 43%) and an increase in the number of unmarried females (34% vs. 61%) were seen. A significant increase in the overall number of rural subjects (17% vs. 34%) and especially in a number of rural females (7% vs. 23%) was also seen. An increase in subjects from middle socioeconomic class (15% vs. 29%) and education up to secondary school (9% vs. 25%) was also seen. A significantly higher number of subjects had a psychiatric disorder (50% vs. 81%) with a significant increase in diagnoses of depression (36% vs. 67%). Family and social issues remain the most common antecedent stressful events. Chemical methods are still the most preferred means, but a higher number (8% vs. 18%) report a history of self-harm. Conclusion: Variations in factors responsible for DSH identified in this comparative study have preventive implications. PMID:28066008

    Snowboard injuries in a Swedish ski area were evaluated from 1989 to 1999. All injured skiers (alpine, telemark, snowboarders) who sought medical attention at the local Medical Center within 48 h of the accident, were asked to answer an injury form. Physicians assessed and treated the injured skiers. There were a total of 1775 injured skiers; 568 injured snowboarders mean age 19 years. The female/male ratio was 34/66%, the injury rate 3/1000 skier days, three times higher than that of alpine skiers. The skill level of the injured snowboard riders improved during the period. The fall/run ratio of the beginners was higher (1.0) and their risk behavior lower (3.9 on visual analogue scale 1-10) in comparison to the advanced riders (0.4 and 6.6, respectively). Injuries were in 54% located to the upper extremity, 35% were wrist/lower arm injuries. Beginners had significantly higher frequency of lower arm/wrist injuries (46%), than average (32%) and advanced riders (20%). The most frequent single diagnosis was wrist/lower arm fracture (20%). Advanced riders tend to have more head/neck injuries than beginners, 17% vs. 13% (NS). Thus, with elevated skill level the injury pattern changed. For injury prevention, wrist guards and helmets are recommended for snowboard riders.

    The Cassini mission at Saturn has provided many surprises on Saturn's rapidly rotating magnetosphere and its interaction with the diverse moons, as well as its interaction with the solar wind. One of the early discoveries was the water-rich composition of the magnetosphere. Its structure and dynamics indicate remarkable injections, periodicities and interchange events. Enceladus, orbiting at 4 RS, was found to have plumes of water vapour and ice which are the dominant source for the inner magnetosphere. Charged water clusters, charged dust and photoelectrons provide key populations in the 'dusty plasma' seen here, as well as chemical complexity in the plume material. Direct pickup is seen near Enceladus and field aligned currents create a spot in Saturn's aurora. At Titan, orbiting at 20 RS, heavy negative and positive ions are seen in the ionosphere, as well as neutrals, all of which have surprising chemical complexity. These provide the source for Titan's haze. Ionospheric plasma is seen in Titan's tail, enabling ion escape to be estimated at 7 tonnes per day. Saturn's ring ionosphere was seen early in the mission, which was oxygen rich and produced photoelectrons; a return will be made in 2017. At Rhea, pickup positive and negative ions indicated weak atmospheres sustained by energetic particle impact, seen in the neutrals also. A weak atmosphere was also seen at Dione. The exosphere production process operates at Jupiter's moons also. Here we review some of the key new results, and discuss the implications for other solar system contexts.

    GEOMAR Helmholtz Centre for Ocean Research Kiel, Germany, started a programme of cooperations with secondary schools in 2003, which has been expanding continually since that time. By active involvement of teachers and students, the Centre's research topics are communicated to schools, and young people are encouraged to develop their interest for biogeosciences. The portfolio of activities includes: project work with schools over periods from one day to several months, individual student theses at the research centre, internships, a weekly "Research Club" allowing individual experiments, summer school programmes, teacher training courses, joint activities with international partners and a video-project in which students portray scientific aspects of oceanic oxygen minimum zones (in the context of the Collaborative Research Center SFB 754) to other students. Essential prerequisites for these activities are the direct involvement of the Centre's researchers who contribute their expertise and act as role-models for the students, dedicated staff for coordination and continuity, and financial and structural support both at the research centre and the schools.

    A retrospective study was undertaken to evaluate whether the initial outcome of two types of reduction mammaplasty techniques (vertical scar reduction mammaplasty vs. the inverted-T scar reduction mammaplasty) remains stable in the long term: Sixty-nine patients who had undergone breast reduction surgery in the period 1997-2000 at the Department of Reconstructive Plastic Surgery at the Medical Center of Leeuwarden were willing and able to participate in this study. A structured questionnaire was used to assess the degree of patient satisfaction. For subjective evaluation, the Strasser Grading System on photographs at the 3 months after surgery and after long-term follow-up (10 years) was used. The median general appreciation mark for the entire surgical procedure given by patients was 8 (1-10) on a scale from 1 to 10. Forty-six of the 69 patients could be scored according to Strasser: at 3 months in 17 patients (37%) the result was 'good', in 21 patients (46%) 'mediocre' and in eight patients (17%) 'poor'. After 10 years, in 37 of the patients (80%) the result was 'good', in six patients (13%) 'mediocre' and in three patients (7%) 'poor'. At 3 months, there was a higher incidence of bottoming out in the vertical scar group (one on two patients) as compared to the inverted-T scar group (one on 10 patients); however, at the 10-years follow-up bottoming out was 50% in the inverted-T scar group and 20% in the vertical scar group. Despite bottoming out, in both the vertical scar reduction mammaplasty technique and the inverted-T scar reduction mammaplasty technique, high patient satisfaction rates are achieved that remains for years.

  6. AEROCE - 10 Years of Atmospheric Chemistry at Bermuda

    Savoie, D. L.

    2001-12-01

    concentrations of mineral dust occur during the summer when advection of air from lower latitudes frequently carries Saharan dust to the site. Along with the dust, Bermuda receives pollution from Europe as well as Africa. However, the major source for pollutants at Bermuda is North America. The highest concentrations of the pollutant aerosol species are associated with rapid and direct boundary layer transport from the United States. Natural processes also play an important role. Dimethylsulfide (DMS), emitted from biological sources in the ocean, is converted to aerosol products, contributing about 30 per cent of the annual mean nonsea-salt sulfate at Bermuda. Chlorine derived from sea-salt may play a significant role in atmospheric oxidation reactions. Another major issue addressed in AEROCE was the rate of transfer of the atmospheric species into the ocean. Removal by precipitation is the major sink for many types of marine aerosols. Scavenging ratios (SRs) are often used to characterize and parameterize the removal flux. When calculated from data averaged over long time periods (e.g., a year or more), SRs are reasonably consistent (within a factor of two) over extensive marine regions. Scavenging processes are, however, complex and vary greatly over time and space. This is reflected in monthly SRs that vary over factors of 2 to 5 at Bermuda, and in daily SRs that vary over an order of magnitude. Consequently, removal fluxes parameterized over short periods of time are still highly uncertain.

    CHARMM-GUI, http://www.charmm-gui.org, is a web-based graphical user interface that prepares complex biomolecular systems for molecular simulations. CHARMM-GUI creates input files for a number of programs including CHARMM, NAMD, GROMACS, AMBER, GENESIS, LAMMPS, Desmond, OpenMM, and CHARMM/OpenMM. Since its original development in 2006, CHARMM-GUI has been widely adopted for various purposes and now contains a number of different modules designed to set up a broad range of simulations: (1) PDB Reader & Manipulator, Glycan Reader, and Ligand Reader & Modeler for reading and modifying molecules; (2) Quick MD Simulator, Membrane Builder, Nanodisc Builder, HMMM Builder, Monolayer Builder, Micelle Builder, and Hex Phase Builder for building all-atom simulation systems in various environments; (3) PACE CG Builder and Martini Maker for building coarse-grained simulation systems; (4) DEER Facilitator and MDFF/xMDFF Utilizer for experimentally guided simulations; (5) Implicit Solvent Modeler, PBEQ-Solver, and GCMC/BD Ion Simulator for implicit solvent related calculations; (6) Ligand Binder for ligand solvation and binding free energy simulations; and (7) Drude Prepper for preparation of simulations with the CHARMM Drude polarizable force field. Recently, new modules have been integrated into CHARMM-GUI, such as Glycolipid Modeler for generation of various glycolipid structures, and LPS Modeler for generation of lipopolysaccharide structures from various Gram-negative bacteria. These new features together with existing modules are expected to facilitate advanced molecular modeling and simulation thereby leading to an improved understanding of the structure and dynamics of complex biomolecular systems. Here, we briefly review these capabilities and discuss potential future directions in the CHARMM-GUI development project. © 2016 Wiley Periodicals, Inc.

    Peripheral arterial pseudoaneurysms are quite common in Northern India (Punjab Province) and thus a common presenting complaint of varied etiology. The objective of this study was to evaluate the clinical outcome of patients presenting with peripheral arterial pseudoaneurysms of varied etiology. Retrospective analysis of medical records of patients with diagnosis of peripheral arterial pseudoaneurysm from 1 May 2001 to 30 October 2009 was done. In the prospective period from 1 November 2009 to 30 April 2011, the patients were personally examined by the authors and followed up till discharge from the hospital and subsequently at 2 weeks, 1 month, 3 months, and 6 months postdischarge from the hospital. We studied 50 patients (13 in the prospective group and 37 in the retrospective study group). Intravenous drug abuse (26 cases) followed by trauma (nine cases) was the commonest etiology. Femoral artery was the commonest artery involved (37 cases). A pulsatile mass with localized tenderness was the commonest presentation. All patients underwent surgical treatment with 36 (72 %) patients undergoing ligation and excision of the pseudoaneurysm. Six (12 %) patients underwent revascularization with reverse saphenous vein graft. Five (10 %) patients underwent primary repair, and three (6 %) patients were managed by putting a synthetic ePTFE graft. Postoperative wound infection was seen in 18 (36 %) patients, and 33 (66 %) patients had an uneventful recovery. In pseudoaneurysms, surgical repair at the early instance carries a favorable prognosis. If feasible, reverse saphenous vein grafting is the best conduit for repair. Synthetic vascular graft (ePTFE) can be used in case autologous saphenous vein is not available. Excision and ligation is safe, and we recommend it as the treatment of choice for infected arterial pseudoaneurysms.

    Direct imaging planet-finders like the Gemini Planet Imager (GPI) allow for direct imaging of exoplanets with orbital periods beyond ~10 years that are still close enough to their host stars to undergo detectable orbital motion on year or multi-year timescales, creating a need for methods that rapidly characterize newly discovered planets using relative astrometry covering a short fraction of an orbital period. We address this problem with Orbits for the Impatient (OFTI), a statistically robust and computationally efficient Bayesian rejection sampling method for fitting orbits to astrometric datasets covering small orbital fractions from directly imaged exoplanets, brown dwarfs, and wide-orbit stellar binaries. We demonstrate that OFTI produces valid orbital solutions by directly comparing its outputs with those of two Markov Chain Monte Carlo (MCMC) implementations, and compare the computational speeds of OFTI and MCMC as a function of orbital fraction spanned by input astrometry. We find that for well-sampled orbits with astrometry covering less than 15% of the total orbital period, OFTI converges on the correct orbital solution in orders of magnitude less CPU time than MCMC. Exoplanet observations with space missions such as the WFIRST coronagraph present a similar problem of sparse sampling, and we show how these methods can efficiently constrain the orbital inclination, phase, and separation of a planet such as 47 Uma c. Finally, we present some of the first orbital fits to astrometry from directly imaged exoplanets and brown dwarfs in the literature, including GJ 504 b, CD-35 2722 B, kappa And b, and HR 3549 B.

    Background. Sweat gland carcinoma is a rare malignancy with a high metastatic potential seen more commonly in elderly patients. The scalp is the most common site of occurrence and it usually spreads to regional lymph nodes. Liver, lungs, and bones are the most common sites of distant metastasis. Late lung metastasis of sweat gland adenocarcinoma after a time span of 5 years is extremely rare. Aim. We report a patient with late lung metastasis of a primary sweat gland carcinoma 10 years after initial surgical resection. Conclusion. Sweat gland carcinomas are rare cancers with a poor prognosis. Surgery in the form of wide local excision and lymph node dissection is the mainstay of treatment. Late pulmonary metastases with a latency of 10 years have never been reported in the literature. This is the first clinical documentation of late lung metastasis from sweat gland carcinoma with a latency period of 10 years.

    Objective: To study the clinical features and treatment outcome of pediatric patients with bony craniovertebral abnormalities. Materials and Methods: The authors studied 189 consecutive cases of pediatric bony craniovertebral junction abnormalities operated between 2001 and March, 2010. Results: The pathologies were developmental (n = 162), traumatic (n = 18) and tuberculous (n = 9). Surgical procedures included transoral decompression (n = 118), occipitocervical fusion (OCF, n = 139), C 1 -C 2 fusion (n = 45), and posterior fossa decompression (n = 5). Methods for OCF included contoured stainless steel rods (n = 86), titanium lateral mass screws and plates (n = 47) and steel wires (n = 6). Constructs of all patients of posterior fixation with contoured rods and wires or lateral mass screw and rod who could be followed up were either stable/fused or were fused and stable. No implant failure was noticed among these two surgical procedures. However, 6 patients with C 1-C 2 fusion had broken wires on follow-up requiring repeat posterior fixation. Good neurological outcome was observed even in poor-grade patients. No significant effect on the curvature or growth of the spine was observed at follow-up. Conclusions: Pediatric craniovertebral junction anomalies can be managed successfully with good outcomes using a low cost contoured rod and wires. PMID:22069436

    This study identified longitudinal risk factors for body dissatisfaction (BD) over a 10-year period from adolescence to young adulthood. Participants (N = 2134; age at baseline: M =15.0, SD =1.6 years) provided two waves of survey data. A 6-step hierarchical linear regression analysis examined the predictive contribution of Time 1 BD, weight status, demographics, family and peer environmental factors, and psychological factors. Among females, Asian race/ethnicity, low self-esteem, greater BD, and higher body mass index during adolescence contributed significantly to predicting greater BD at 10-year follow up (R2 = 0.27). Among males, demographics (i.e., Asian, other-mixed ethnicity, education attainment), depressive symptoms, greater BD, higher body mass index, more parent communication, and less peer weight teasing during adolescence contributed to BD at follow-up (R2 = 0.27). Findings indicate who may be at greatest risk for BD in young adulthood and the types of factors that should be addressed during adolescence. PMID:25045599

    High-temperature heat pipes are being evaluated for use in energy conversion applications such as fuel cells, gas turbine re-combustors, Stirling cycle heat sources; and with the resurgence of space nuclear power both as reactor heat removal elements and as radiator elements. Long operating life and reliable performance are critical requirements for these applications. Accordingly, long-term materials compatibility is being evaluated through the use of high-temperature life test heat pipes. Thermacore, Inc., has carried out a sodium heat pipe 10-year life test to establish long-term operating reliability. Sodium heat pipes have demonstrated favorable materials compatibility and heat transport characteristics at high operating temperatures in air over long time periods. A representative one-tenth segment Stirling Space Power Converter heat pipe with an Inconel 718 envelope and a stainless steel screen wick has operated for over 87,000 hr (10 years) at nearly 700 C. These life test results have demonstrated the potential for high-temperature heat pipes to serve as reliable energy conversion system components for power applications that require long operating lifetime with high reliability. Detailed design specifications, operating history, and post-test analysis of the heat pipe and sodium working fluid are described. Lessons learned and future life test plans are also discussed.

    We underline the clinical importance of a specific eating disorder in 3 to 10 years old children, when the majority of the works about the prepubertal eating disorders focus either on the period just preceding adolescence (often between 10 and 13 years), or on the second half of the first year of the baby. Within the eating disorders described in the literature, we compare the clinical presentation of most of these 3 to 10 years old children with the food avoidance emotional disorder described during adolescence. These problems of eating behaviour (various selective eating with or without provoked vomiting) are ignored for a long time in these young children because of quite a satisfactory growth, but these children are often seen in emergency rooms because of a brutally complete eating refusal. Therapeutic consultations allow these children to express their fears about diseases, poisoning and death, for themselves or for their close relations, in particular the mother, without endangering their body. The early recognition and care of these difficulties of conciliation between the body and the thoughts impose a narrow collaboration between paediatric and psychiatric staffs.

    Background: Many women suffer from some degree of intrauterine adhesions (IUAs) presenting with various clinical symptoms and signs. Hysteroscopy is the mainstay of diagnosis, classification, and treatment of the IUA. Aim: This study was undertaken to review the clinical features and treatment outcome in patients diagnosed with Asherman's syndrome at the University of Maiduguri Teaching Hospital (UMTH), Maiduguri, over a 10 years period, 1997–2006. Subjects and Methods: This is a retrospective study of cases of Asherman's syndrome managed at the UMTH over a 10-year period, from January 1, 1997 to December 31, 2006. Case records of the patients were retrieved from medical records' Department. Sociodemographic and clinical information relating to clinical presentations, treatment modalities, and outcomes were collated. The data were analyzed using SPSS 16.0 Statistical Computer Package (SPSS Inc., IL, USA 2006). Chi-square and binary logistic regression were used for inferential statistics. Results: Asherman's syndrome constituted 8.1% (81/996) of all gynecological operations in UMTH during the study period. The case records retrieval rate was 96.3% (78/81 folders). Most of the patients, 59% (46/78) were in their third decade and majority 85.9% (67/78) were married. The most common risk factor was pregnancy-associated, accounting for 61.5% (48/78). Infertility and hypomenorrhea were the most common mode of presentations in 55.1% (43/78) and 32.1% (25/78) of cases, respectively. Most of the patients 85.9% (67/78) were treated by blind dilatation and curettage (D/C), Foley's catheter insertion and estrogen-progesterone combination. Correction of menses was seen in 37.2% (29/78) of the patients while the pregnancy rate was 32.1% (25/78). On binary logistic regression age of the respondents, multigravidity, and previous pelvic surgeries for pregnancy (C/S and D/C for abortion) emerged as the only respondent's related risk factors associated with the development of

    Video capsule endoscopy (CE) for evaluation the esophagus (ECE), small bowel (SBCE) and the colon (CCE) is particularly useful in pediatrics, because this imaging modality does not require ionizing radiation, deep sedation or general anesthesia. The risk of capsule retention appears to be dependent on indication rather than age and parallels the adult experience by indication, making SBCE a relatively safe procedure with a significant diagnostic yield. The newest indication, assessment of mucosal change, greatly enhances and expands its potential benefit. The diagnostic role of CE extends beyond the SB. The use of ECE also may enhance our knowledge of esophageal disease and assist patient care. Colon CCE is a novel minimally invasive and painless endoscopic technique allowing exploration of the colon without need for sedation, rectal intubation and gas insufflation. The limited data on ECE and CCE in pediatrics does not yet allow the same conclusions regarding efficacy; however, both appear to provide safe methods to assess and monitor mucosal change in their respective areas with little discomfort. Moreover, although experience has been limited, the patency capsule may help lessen the potential of capsule retention; and newly researched protocols for bowel cleaning may further enhance CE's diagnostic yield. However, further research is needed to optimize the use of the various CE procedures in pediatric populations.

    Objective: To report our 10-year diagnosis and treatment experience of acute urogenital and genitalia tract traumas and outline the management of the traumatic injury. Methods: We reviewed the diagnoses and treatments of 208 cases of acute kidney, ureter, bladder, urethra, or male genitalia injuries in our department between March 2002 and March 2012. The patient data including general information, injury position and mechanism, diagnosis and treatment, the follow-up information was analyzed and summarized. Results: Of 62 patients with renal injury examined by ultrasound and computed tomography (CT) examination, 45 were treated conservatively, 9 with superselective arterial embolization, and 8 with nephrectomy. Intravenous pyelogram (IVP) was conducted in two patients with ureteral injury, one was treated with cystoscopic ureteral catheterization and the other with ureteric reimplantation. Bladder injury (6 patients) confirmed with a waterflood susceptibility test combined with CT scans underwent laparotomy and the bladder suturing was done. Of 92 patients with urethral injury, 6 were treated with a nonoperative approach (indwelling catheter), 18 with urethral realignment, 35 with cystoscopic urethral realignment, 29 with end-to-end anastomotic urethroplasty, and 4 with urethral repairmen. Of the 24 cases with penile injuries, 1 underwent conservative treatment, 8 were treated with debridement and suture ligation, and 15 were managed with suture repair of the penis white membrane. Of the 24 cases with penile injuries, 1 underwent conservative treatment, 8 were treated with debridement and suture ligation, and 15 were managed with suture repair of the penis white membrane. During the follow-up period, 62 patients with renal injury had normal renal function. Neither of the two patients with ureteral injury developed hydronephrosis. Twenty-nine patients with urethral injury suffered from urethral structure. All patients with vesical or genital injury recovered

    Object Little is known about long-term outcomes, including tumor control and adverse radiation effects, in patients harboring vestibular schwannomas (VSs) treated with stereotactic radiosurgery > 10 years previously. The aim of this study was to confirm whether Gamma Knife surgery (GKS) for VSs continues to be safe and effective > 10 years after treatment. Methods A total of 440 patients with VS (including neurofibromatosis Type 2) treated with GKS between May 1991 and December 2000 were evaluable. Of these, 347 patients (79%) underwent GKS as an initial treatment and 93 (21%) had undergone prior resection. Three hundred fifty-eight patients (81%) had a solid tumor and 82 (19%) had a cystic tumor. The median tumor volume was 2.8 cm(3) and the median marginal dose was 12.8 Gy. Results The median follow-up period was 12.5 years. The actuarial 5- and ≥ 10-year progression-free survival was 93% and 92%, respectively. No patient developed treatment failure > 10 years after treatment. According to multivariate analysis, significant factors related to worse progression-free survival included brainstem compression with a deviation of the fourth ventricle (p < 0.0001), marginal dose ≤ 13 Gy (p = 0.01), prior treatment (p = 0.02), and female sex (p = 0.02). Of 287 patients treated at a recent optimum dose of ≤ 13 Gy, 3 (1%) developed facial palsy, including 2 with transient palsy and 1 with persistent palsy after a second GKS, and 3 (1%) developed facial numbness, including 2 with transient and 1 with persistent facial numbness. The actuarial 10-year facial nerve preservation rate was 97% in the high marginal dose group (> 13 Gy) and 100% in the low marginal dose group (≤ 13 Gy). Ten patients (2.3%) developed delayed cyst formation. One patient alone developed malignant transformation, indicating an incidence of 0.3%. Conclusions In this study GKS was a safe and effective treatment for the majority of patients followed > 10 years after treatment. Special attention

    generated by heating, which then exchange energy with the magnetic system), a TRM can be acquired with minimal heating of the bulk sample, thus potentially minimizing sample alteration. The theory of TRM acquisition is best developed for single-domain (SD) grains, and most paleointensity techniques are predicated on the assumption that the remanence is carried predominantly by SD material. Because the vast majority of geological materials are characterized by a larger magnetic grain size, efforts to expand paleointensity studies over the past decade have focused on developing TRM theories and paleointensity methods for pseudo-single-domain (PSD) and MD samples. Other workers have been exploring the potential of SD materials that were not traditionally used in paleointensity studies, such as ash flow tuffs, submarine basaltic glass, and single silicate crystals with magnetite inclusions. The latter has the potential to shed light on early Earth processes, given that the fine-grained inclusions may be resistant to alteration over long time scales. We will review the major paleointensity techniques in use today, with special attention paid to the advantages and disadvantages of each. Techniques will be illustrated with examples highlighting new paleointensity applications to geologic processes at a variety of timescales.

    Hereditary ataxias associated with cerebellar atrophy are a heterogeneous group of disorders. Selection of appropriate clinical and genetic tests for patients with cerebellar atrophy poses a diagnostic challenge. Neuroimaging is a crucial initial investigation in the diagnostic evaluation of ataxia in childhood, and the presence of cerebellar atrophy helps guide further investigations. We performed a detailed review of 300 patients with confirmed cerebellar atrophy on magnetic resonance imaging over a 10-year period. A diagnosis was established in 47% of patients: Mitochondrial disorders were most common, followed by the neuronal ceroid lipofuscinoses, ataxia telangectasia, and late GM2-gangliosidosis. We review the common causes of cerebellar atrophy in childhood and propose a diagnostic approach based on correlating specific neuroimaging patterns with clinical and genetic diagnoses.

    A dynamic health care industry continues to call upon health care leaders to possess not one but multiple competencies. Inherent personality characteristics of leaders often play a major role in personal as well as organizational success to include those in health care finance positions of responsibility. A replication study was conducted to determine the Myers-Briggs personality-type differences between practicing health care finance professionals in 2014, as compared with a previous 2003 study. Results indicate a significant shift between both independent samples of health care finance professionals over the 10-year period from original high levels of introversion to that of extraversion, as well as higher sensing personality preferences, as compared with the original sample's high level of intuition preferences. Further investigation into the evolving role of the health care finance manager is suggested, while continued alignment of inherent, personal characteristics is suggested to meet ongoing changes in the industry.

    The purpose of this study was to document performance of occupational therapy journals on the metrics of the Journal Citation Reports (JCR), the annually appearing index used as a yardstick to assess the quality of scholarly publications. Outcomes for the field's two indexed journals, the American Journal of Occupational Therapy and OTJR: Occupation, Participation and Health, were assessed over a 10-year period (1996-2005) to determine their overall standing and patterns of change on each of the JCR's five metrics. The mean category ranking for the two journals was generally above the 50th percentile. However, they performed least adequately and evidenced a downward trend over time on the most widely used metric (the journal impact factor). Possible reasons underlying this latter result are explored, pressing implications of the overall findings for practice and research are discussed, and strategic steps toward ethically safeguarding the profession's viability are offered.

    Based on four empirical studies conducted over a 10-year time period from 1999 to 2008 we investigate how local software processes interact with global changes in the software development context. In 1999 companies were developing software at high speed in a desperate rush to be first-to-market. In 2001 a new high speed/quick results development process had become established practice. In 2003 changes in the market created the need for a more balanced view on speed and quality, and in 2008 companies were successfully combining agile and plan driven approaches to achieve the benefits of both. The studies reveal a twostage pattern in which dramatic changes in the market causes disruption of established practices, experimentation, and process adaptations followed by consolidation of lessons learnt into a new (and once again mature) software development process. Limitations, implications, and areas for future research are discussed.

    In this study, survival analysis is used to examine time to rearrest for both domestic violence and nondomestic violence crimes among a cohort of domestic violence offenders (N = 286) over a 10-year period. In addition, risk factors for rearrest such as demographic, offending history, and batterer treatment variables are examined to determine their influence on domestic and nondomestic violence recidivism. Overall, the results suggest that approximately half of domestic violence offenders are rearrested. Furthermore, among those who are rearrested, they are rearrested fairly quickly and for generalized (both domestic and nondomestic violence offenses) versus specialized offending. Risk factors associated with both types of rearrest included age, marriage, and domestic violence offense history. Several additional risk factors were unique to rearrest type. Study limitations are explicitly stated and policy implications are discussed.

    Given the negative consequences of divorce on health and well-being, it is important to try to identify its predictors. In the current study we used data from the National Survey of Midlife Development (N = 2801) to examine the longitudinal effects of lack of joint goal planning with a romantic relationship partner on divorce over a 10-year period. Multilevel regression analyses showed that lack of joint planning with the relationship partner was associated with a 19% increase in the odds of divorce, even when controlling for various demographic (i.e., age, gender, relationship length, number of children in the household), individual (i.e., neuroticism, positive affect, negative affect, physical symptoms, planning), and relationship (i.e., marital empathy, partner strain, partner disagreement, marital satisfaction, commitment). These results demonstrate the importance of considering one’s partner when making decisions and plans for the future, given that it has clear implications for relationship dissolution. PMID:27668863

    Mining, especially underground coal mining, has always been a dangerous occupation. Injuries, unfortunately, even those resulting in death, are one of the major occupational risks that all miners live with. Despite the fact that all workers are aware of the risk, efforts must be and are being made to increase the safety of mines. Injury monitoring and data analysis can provide us with valuable data on the causes of accidents and enable us to establish a correlation between the conditions in the work environment and the number of injuries, which can further lead to proper preventive measures. This article presents the data on the injuries in Serbian coal mines during a 10-year period (2000-2009). The presented results are only part of an ongoing study whose aim is to assess the safety conditions in Serbian coal mines and classify them according to that assessment.

    The results of skin biopsies over a 10 year period were reviewed from the outpatient dermatology clinic at the Brody School of Medicine in Greenville, North Carolina. This research was conducted because there are very few studies that characterize this information over a long-term horizon. The biopsy rate per patient encounter, the clinical reason for the biopsy, the biopsy outcomes, the distribution of cutaneous malignancies per encounter, and the distribution of the subtypes of basal cell carcinoma, squamous cell carcinoma, and melanoma were analyzed. Biopsy logs from January 1, 2001 to December 31, 2010 were reviewed. Our investigation found that 20% of patient encounters resulted in a biopsy. Of these biopsies, 87.9% were performed to rule out malignancy and 12.1% were completed on patients suspected of having inflammatory skin conditions. The basal cell carcinomas diagnosed in Greenville, NC have more aggressive histologic subtypes compared to other studies, whereas the squamous cell carcinomas and melanomas were less aggressive.

    The purpose of this study was to detect latent periodicity in the presence of deletions or insertions in the analyzed data, when the points of deletions or insertions are unknown. A mathematical method was developed to search for periodicity in the numerical series, using dynamic programming and random matrices. The developed method was applied to search for periodicity in the Euro/Dollar (Eu/) exchange rate, since 2001. The presence of periodicity within the period length equal to 24 h in the analyzed financial series was shown. Periodicity can be detected only with insertions and deletions. The results of this study show that periodicity phase shifts, depend on the observation time. The reasons for the existence of the periodicity in the financial ranks are discussed.

    Ballet dancers are high-performance athletes who are particularly susceptible to a wide variety of musculoskeletal injuries. However, they are relatively understudied, and data on their injury rates are lacking. This retrospective study features the largest aggregate data on professional ballet dancers to date and aims to identify the most common diagnoses and areas of injury in this unique population to better direct preventative and clinical practices. The study encompassed a 10-year period from January 2000 to December 2010 of dancers from a single company. Data regarding the dancers' age, gender, location of injury, and diagnosis were collected from workers' compensation claims, company records, and medical records maintained by the treating doctors. These were analyzed to determine metrics on injury incidence, frequency, and diagnosis. Over the 10-year span, 574 injuries occurred. There were approximately 52 dancers per year for a total of 153 who danced at least one complete season during the study period. The average age was 27, and 53% were female. Given turnover with retirement and replacements, the total number of dancer-years was 520, indicating an injury incidence per annum of 1.10 (574 injuries per 520 dancer-years). The most common locations of injury were foot and ankle and the lumbar spine, with the three most common diagnoses making up greater than a third (37%) of the total. As the current largest study in professional ballet, the findings set the benchmark metrics for musculoskeletal injury to the foot, ankle, and lumbar spine sites. Future studies should aim to identify injury risk factors and modalities for prevention of these injuries.

    ABSTRACT Aim: The aim of this study was to determine the oral hygiene facilitators and barriers for 10 years old Greek children, via a questionnaire and clinical examination. Materials and methods: This was a cross-sectional study of 266, 10 years old, children recruited from schools in 3 locations in Greece. Data were collected via questionnaires and clinical examination. Questionnaires referred to Children’s oral hygiene knowledge, behavior and attitude as well as parents’ oral hygiene behavior and educational level. Children were clinically examined by two calibrated pediatric dentists using a WHO probe and artificial light to assess dental plaque (hygiene index-HI), gingivitis (simplified gingival index-GIs) and dental caries (DMFT-BASCD criteria). Results: Regarding oral hygiene knowledge, although 80% of the children were literate of the proper means of oral hygiene, only 58.64% brushed their teeth twice daily and 36.84% used dental floss. Children’s oral hygiene knowledge was positively correlated with both parental brushing frequency (ρ = 0.175, p < 0.05) and educational level (ρ = -0.216, p < 0.05). Toothpaste use was reported by 92.11% of the children. Regarding Children’s attitude, 62.28% were concerned whether their teeth were clean, with girls showing greater concern than boys (p < 0.001). Their reported beliefs regarding brushing avoidance were boredom (84.06%), low oral health literacy (73.91%) and forgetfulness (56.52%). Conclusion: Oral hygiene facilitators were found to be the concern about how clean were their teeth, oral health literacy of both children and parents and toothpaste appeal to children. Oral hygiene barriers were Children’s boredom, low oral health literacy, forgetfulness and low socioeconomic level. How to cite this article: Angelopoulou M, Kavvadia K, Oulis C, Reppa C.

    The objective of this study was to assess temporal and spatial trends for eight pyrethroids monitored in sediment spanning 10 years from 2006 to 2015 in a residential stream in California (Pleasant Grove Creek). The timeframe for this study included sampling 3 years during a somewhat normal non-drought period (2006-2008) and 3 years during a severe drought period (2013-2015). Regression analysis of pyrethroid concentrations in Pleasant Grove Creek for 2006, 2007, 2008, 2012, 2013, 2014, and 2015 using ½ the detection limit for nondetected concentrations showed statistically significant declining trends for cyfluthrin, cypermethrin, deltamethrin, permethrin, and total pyrethoids. Additional trends analysis of the Pleasant Grove Creek pyrethroid data using only measured concentrations, without nondetected values, showed similar statistically significant declining trends for cyfluthrin, cypermethrin, deltamethrin, esfenvalerate, fenpropathrin, permethrin, and total pyrethroids. Spatial trends analysis for the specific creek sites showed that six of the eight pyrethroids had a greater number of sites with statistically significant declining concentrations. Possible reasons for reduced pyrethroid concentrations in the stream bed in Pleasant Grove Creek during this 10-year period are label changes in 2012 that reduced residential use and lack of precipitation during the later severe drought years of 2013-2015.

    Considering variation of environment temperature and unhomogeneity of background gravitational field, an improved correlation method was proposed to determine the variational period of a torsion pendulum with high precision. The result of processing experimental data shows that the uncertainty of determining the period with this method has been improved about twofolds than traditional correlation method, which is significant for the determination of gravitational constant with time-of-swing method.

  15. 100% Retention of Snowpack Derived Nitrogen Over 10 Years in High Arctic Tundra

    Tundra ecosystems are susceptible to atmospheric nitrogen (N) deposition, increasing as a result of anthropogenic activities as well as climate change. Depositions that get accumulated within the snowpack during winter months are released in spring during snowmelt, providing a periodic input of reactive N in the melt water to such nutrient limited ecosystems. Identifying ecosystem N retention and allocation and how this change over time is important to understanding the long-term consequences of such N depositions to these ecosystems. We reanalysed 10 years later an atmospheric N deposition study established in Svalbard that in 2001 used 15N isotope tracers to determine the fate of N released from melting snowpack. Applications of 15N (99 atom%) at 0.1 and 0.5 g N m-2 were made immediately after snowmelt in 2001 as either Na15NO3 or 15NH4Cl. These applications were approximately 1 × and 5 × the yearly atmospheric deposition rates. In both the previous short-term (one week to two years after 15N tracer application) and our long-term re-sampling (10 years after 15N tracer application), ~67% of the total applied 15N was retained in the ecosystem, irrespective of the N forms or N dose. This meant the tundra had 100% long-term N retention after initial partitioning, suggesting a highly conservative N cycling. Bryophytes, followed by the organic soil horizon and then the microbial biomass formed the greatest short-term 15N sink. Maximum changes in 15N retention from the short- to long-term were observed in the microbial 15N pools, with ~75% of the 15N in soil located in its biomass during the initial partitioning (July 2001) decreasing to ~17% 10 years later. This indicates significant microbial N turnover mostly into stable humus N. In contrast, vascular plants, particularly Salix polaris, showed significant increases (~60%) in their 15N retention after 10 years, indicating a high capacity for acting as a long-term N sink in this tundra ecosystem.

    A double expansion method for the frequency response of finite-length beams with periodic distribution parameters is proposed. The vibration response of the beam with spatial periodic parameters under harmonic excitations is studied. The frequency response of the periodic beam is the function of parametric period and then can be expressed by the series with the product of periodic and non-periodic functions. The procedure of the double expansion method includes the following two main steps: first, the frequency response function and periodic parameters are expanded by using identical periodic functions based on the extension of the Floquet-Bloch theorem, and the period-parametric differential equation for the frequency response is converted into a series of linear differential equations with constant coefficients; second, the solutions to the linear differential equations are expanded by using modal functions which satisfy the boundary conditions, and the linear differential equations are converted into algebraic equations according to the Galerkin method. The expansion coefficients are obtained by solving the algebraic equations and then the frequency response function is finally determined. The proposed double expansion method can uncouple the effects of the periodic expansion and modal expansion so that the expansion terms are determined respectively. The modal number considered in the second expansion can be reduced remarkably in comparison with the direct expansion method. The proposed double expansion method can be extended and applied to the other structures with periodic distribution parameters for dynamics analysis. Numerical results on the frequency response of the finite-length periodic beam with various parametric wave numbers and wave amplitude ratios are given to illustrate the effective application of the proposed method and the new frequency response characteristics, including the parameter-excited modal resonance, doubling-peak frequency response

    Purpose We aimed to determine the quantity and quality of research output of selected Asian countries in the field of total knee arthroplasty (TKA) in the last 10 years. Materials and Methods Top 15 Asian countries were selected according to their gross domestic product. The Science Citation Index Expanded database was used to search for the literature published between 2004 and 2013 using "Total Knee Arthroplasty". The numbers of articles, journals and citations and the contribution of each country were analyzed. The articles were classified according to the type of study and the relative proportion of each type was analyzed. Results Asian surgeons have increasingly contributed to orthopedic literature on TKA for the past 10 years, but the dominant contribution came from only a few countries. The total number of articles published by Asian countries increased by 261%, with Japan producing most of the studies and China showing the maximum growth rate. The majority of studies were published in low impact factor journals. Korea published the highest proportion of articles in high impact factor journals. Clinical papers were most frequent. Conclusions Our identification of research productivity pertaining to TKA among Asian countries gives a unique insight into the level of academic research in the field of TKA in these countries. There is a need to improve the quality of research to enhance the publishing power in high impact journals as well as the need for more basic research and epidemiological studies considering the unique differences among Asian patients undergoing TKA.

    Background: Quality management (QM) became mandatory for the ambulatory sector of the German health care system 10 years ago. Objectives: The aim of this study was to find out how general practitioners (GPs) perceived the introduction of this measure, how they see it today and what they expect of the future concerning QM. Materials and Methods: In a qualitative study, interviews following a semi-structured guideline with GPs were conducted. Following transcription, interviews were coded in triangulation, first inductively, then deductively until saturation was reached. Main topics and code families were agreed on after discussion. Results: There was consensus on the necessity of standardization of basic processes like hygiene. However, the application of QM to an activity that emphasizes personal relationships and communication was seen as barely possible. GPs stated that they reduced QM to a tolerable and for them reasonable minimum. GPs mostly refused certification. The next 10 years were seen with pessimism in terms of more bureaucratic guidelines. Conclusion: The statutory introduction of QM was an attack on medical professionalism. Instead of passive resistance and reduction of QM to a minimum, engaged independent quality work might help to regain the trust of society we seem to have lost and restore the professional autonomy we need for our work.

    Relationships between skeletal maturation and fundamental motor skills and gross motor coordination were evaluated in 429 children (213 boys and 216 girls) 7-10 years. Skeletal age was assessed (Tanner-Whitehouse 2 method), and stature, body mass, motor coordination (Körperkoordinations Test für Kinder, KTK) and fundamental motor skills (Test of Gross Motor Development, TGMD-2) were measured. Relationships among chronological age, skeletal age (expressed as the standardised residual of skeletal age on chronological age) and body size and fundamental motor skills and motor coordination were analysed with hierarchical multiple regression. Standardised residual of skeletal age on chronological age interacting with stature and body mass explained a maximum of 7.0% of the variance in fundamental motor skills and motor coordination over that attributed to body size per se. Standardised residual of skeletal age on chronological age alone accounted for a maximum of 9.0% of variance in fundamental motor skills, and motor coordination over that attributed to body size per se and interactions between standardised residual of skeletal age on chronological age and body size. In conclusion, skeletal age alone or interacting with body size has a negligible influence on fundamental motor skills and motor coordination in children 7-10 years.

    Objective The authors examined the relationship between cannabis use and the course of illness in schizophrenia over 10 years following first psychiatric hospitalization. Method We assessed 229 patients with a schizophrenia-spectrum disorder five times: during the first admission, and 6 months, 2 years, 4 years, and 10 years later. Ratings of cannabis use and psychiatric symptoms (psychotic, negative, disorganized, and depressive) were made at each assessment. Results The lifetime rate of cannabis use was 66.2%, and survival analysis revealed that this usage was associated with an earlier onset of psychosis. The rates of current use ranged from 10% to 18% across assessments. Cannabis status was moderately stable, with concordance between waves ranging rtet = 0.48 – 0.78. Mixed-effects logistic regression revealed that changes in cannabis use were associated with changes in psychotic symptoms over time even after gender, age, socio-economic status, other drug use, antipsychotic medication use, and other symptoms were controlled. Structural equation modeling indicated that the association with psychotic symptoms was bi-directional. Conclusions Cannabis use is associated with an adverse course of psychotic symptoms in schizophrenia, and vice versa, even after taking into account other clinical, substance, and demographic variables. The specificity of this relationship suggests that clinical interventions to reduce cannabis use may be best targeted at individuals with prominent psychotic symptoms. PMID:20478874

    Introduction Helicobacter pylori (H. pylori) occurs throughout the world and causes gastroduodenal diseases. There is data indicating a change in the prevalence of H. pylori infection worldwide. The prevalence of H. pylori is 80% in Turkey, while it is higher in many developing countries, and the rate of infection varies throughout the world. In many developing countries, the prevalence of infection exceeds 90% by adulthood. Aim To determine the change in the rate of H. pylori infection in gastric ulcers and duodenal ulcers for a 10-year period in a single centre. Material and methods The study population included 550 patients (342 in 2004, 208 in 1994) with gastric and duodenal ulcers. Results In 2004 there were 125 (36.5%) patients with gastric ulcer and 217 patients with duodenal ulcer (64.5%). CLO test positivity was 39.2% in patients with gastric ulcers and 60% in patients with duodenal ulcers. In 1994 there were 208 patients (159 duodenal ulcers, 49 gastric ulcers). Urease test was positive in 74.2% of patients with duodenal ulcer and in 65.2% of patients with gastric ulcer. The decrease in the rate of urease positivity in patients with gastric ulcer was statistically significant (p = 0.01) during this 10-year period. Conclusions In the present study we found that the urease positivity decreased significantly in patients with gastric ulcer between 1994 and 2004. PMID:26516382

    This autoethnography withdraws from information accumulated through a 10-year period of daily-weekly-monthly descriptive observation-recording (triangulated- parents & house-helper) of caregiving and rehabilitating of our brain injured son (survivor/care-receiver). We present it as an interactive voice of verbal conversation, thoughts, insights, and interpretations. It is delivered as a series of articulation intra-pulsated with our interrogation of societal-cultural-religious perspectives, norms and biases, and aligns with the CAP (Creative Analytical Practices) method of Ellis. This autoethnography glows from the richness of information which encapsulates the challenges confronting us the aging parent caregivers, the gradual incremental mind mending achievement of our son, and the interactive verbalizations and thoughts, of the caregivers, care-receiver, and other persons. The overwhelming mental and physical pain and struggle of the survivor and the aging caregivers and their sense of celebratory-satisfaction with rehabilitation progress are highlighted. Interpretation and valuation of positive and negative responses of other persons provide a critical matrix to this autoethnography. We intend to inform other caregivers and relevant healthcare professionals through this autoethnography. PMID:25763170

    Objective We aimed to identify and describe the clinicopathologic characteristics of tumors of the eye and ocular adnexa at the Philippine Eye Research Institute. Methods The pathology reports of specimens submitted to the Ocular Pathology Section of the Philippine Eye Research Institute over a 10-year period (2003–2012) were reviewed, and collected data was subjected to descriptive statistical tabulation and analysis. Results A total of 1,551 histologically confirmed tumors were included. Of these, 254 were from the conjunctiva (155 benign, 99 malignant), 530 from the eyelids (360 benign, 170 malignant), 394 were intraocular tumors (21 benign, 373 malignant), and 373 were from the orbit (231 benign, 142 malignant). Retinoblastoma was the most common tumor of the eye and ocular adnexa in the series, accounting for 43.2% of all malignancies. Squamous cell carcinoma was the most frequent cancer of the conjunctiva, while basal cell carcinoma and sebaceous gland carcinoma were the most common eyelid malignancies. Orbital malignancies had a bimodal age distribution, with rhabdomyosarcoma being most frequent in children, while in adults, lymphoma was most common, followed by lacrimal gland carcinomas. Conclusion The majority of tumors of the conjunctiva, eyelids, and orbit were benign, while most intraocular tumors were malignant, with retinoblastoma being the most common. PMID:26185414

    It is 10 years since severe acute respiratory syndrome (SARS) emerged, and East and Southeast Asia retain a reputation as a hot spot of emerging infectious diseases. The region is certainly a hot spot of socioeconomic and environmental change, and although some changes (e.g., urbanization and agricultural intensification) may reduce the probability of emerging infectious diseases, the effect of any individual emergence event may be increased by the greater concentration and connectivity of livestock, persons, and products. The region is now better able to detect and respond to emerging infectious diseases than it was a decade ago, but the tools and methods to produce sufficiently refined assessments of the risks of disease emergence are still lacking. Given the continued scale and pace of change in East and Southeast Asia, it is vital that capabilities for predicting, identifying, and controlling biologic threats do not stagnate as the memory of SARS fades.

    BACKGROUND: Gastric banding is one of the simplest surgical procedures for the treatment of morbid obesity. We performed more than 150 'laparotomy' (open) gastric bandings and more than 50 'laparoscopic' bandings in the last 1 0 years. METHODS: In most procedures we used non-adjustable bands, but since the beginning of 1995 we have used adjustable silicone banding. RESULTS: The 5- and 10-year follow-up weight loss results are encouraging. The average long-term weight loss was 35.5 kg. Since 1993, we performed all the procedures laparoscopically, and the postoperative complications decreased from 18.5% in the 'laparotomy' group to 9.5% in the 'laparoscopic' group, with the majority being esophagus and outlet area irritation. CONCLUSION: Gastric banding itself and especially the minimally invasive laparoscopic approach is an easy technical procedure. The long-term weight loss results and the reoperation rate are acceptable for bariatric surgery criteria.

    Objective To ascertain worker health characteristics and psychosocial factors associated with changes in body weight and total cholesterol (TC) among two production operation populations. Methods We performed descriptive and predictive analysis of questionnaire data and biomedical measurements from two prospective cohort studies. Our key outcomes were changes in weight, and TC over 5–10 years between baseline and exit assessments. Results 146 subjects were analyzed. Increases in weight were associated with belief in being overweight and baseline overweight and obesity. Increases in TC levels were associated with female gender, belief that TC levels were “not good,” and feeling depressed. Conclusion Most of the reported associations with increases in weight and TC levels are amenable to interventions and may be a target for workplace intervention programs. PMID:26147542

    2008-01-01

    Objectives To determine the visual acuity outcome at 10 years of age for children less than 7 years of age when enrolled in a treatment trial for moderate amblyopia. Methods In a multi-center clinical trial, 419 children with amblyopia (20/40 to 20/100) were randomized to patching or atropine eye drops for 6 months. Two years after enrollment, a subgroup of 188 children entered long-term follow-up. Treatment after 6 months was at the discretion of the investigator; 89% of children were treated. Main outcome measure Visual acuity at age 10 years with the electronic ETDRS test. Results The mean amblyopic eye acuity, measured in 169 patients, at age 10 years was 0.17 logMAR (approximately 20/32) and 46% of amblyopic eyes were 20/25 or better. Age < 5 years at the time of entry into the randomized trial was associated with a better visual acuity outcome (P<0.001). Mean amblyopic and sound eye visual acuities at age 10 years were similar in the original treatment groups (P= 0.56 and 0.80, respectively). Conclusion At age 10 years the improvement of the amblyopic eye is maintained, although residual amblyopia is common following treatment initiated at 3 to <7 years of age. The outcome is similar regardless of initial treatment with atropine or patching. Application to Clinical Practice Patching and atropine eye drops produce comparable improvement in visual acuity that is maintained through age 10 years.

    Purpose: We have previously reported on the mortality, morbidity, and 5-year survival of 458 patients who underwent radical radiotherapy or surgery for invasive bladder cancer in Yorkshire from 1993 to 1996. We aim to present the 10-year outcomes of these patients and to reassess factors predicting survival. Methods and Materials: The Northern and Yorkshire Cancer Registry identified 458 patients whose cases were subjected to Kaplan-Meier all-cause survival analyses, and a retrospective casenote analysis was undertaken on 398 (87%) for univariate and multivariate Cox proportional hazards modeling. Additional proportional hazards regression modeling was used to assess the statistical significance of variables on overall survival. Results: The ratio of radiotherapy to cystectomy was 3:1. There was no significant difference in overall 10-year survival between those who underwent radiotherapy (22%) and radical cystectomy (24%). Univariate analyses suggested that female sex, performance status, hydronephrosis and clinical T stage, were associated with an inferior outcome at 10 years. Patient age, tumor grade, treatment delay, and caseload factors were not significant. Multivariate analysis models were created for 0-2 and 2-10 years after treatment. There were no significant differences in treatment for 0-2 years; however, after 2 years follow-up there was some evidence of increased survival for patients receiving surgery compared with radiotherapy (hazard ratio 0.66, 95% confidence interval: 0.44-1.01, p = 0.06). Conclusions: a 10-year minimum follow-up has rarely been reported after radical treatment for invasive bladder cancer. At 10 years, there was no statistical difference in all-cause survival between surgery and radiotherapy treatment modalities.

    2010-01-14

    The direct approach to gravitation and electrostatics (DAGE) algorithm is an accurate, efficient, and flexible method for calculating electrostatic potentials. In this paper, we show that the algorithm can be easily extended to consider systems with many different kinds of periodicities, such as crystal lattices, surfaces, or wires. The accuracy and performance are nearly the same for periodic and aperiodic systems. The electrostatic potential for semiperiodic systems, namely defects in crystal lattices, can be obtained by combining periodic and aperiodic calculations. The method has been applied to an ionic model system mimicking NaCl, and to a corresponding covalent model system.

    Background and purpose Uncemented acetabular components in primary total hip arthroplasty (THA) are commonly used today, but few studies have evaluated their survival into the second decade in young and active patients. We report on a minimum 10-year follow-up of an uncemented press-fit acetabular component that is still in clinical use. Methods We examined the clinical and radiographic results of our first 121 consecutive cementless THAs using a cementless, grit-blasted, non-porous, titanium alloy press-fit cup (Allofit; Zimmer Inc., Warsaw, IN) without additional screw fixation in 116 patients. Mean age at surgery was 51 (21–60) years. Mean time of follow-up evaluation was 11 (10–12) years. Results At final follow-up, 8 patients had died (8 hips), and 1 patient (1 hip) was lost to follow-up. 3 hips in 3 patients had undergone acetabular revision, 2 for deep infection and 1 for aseptic acetabular loosening. There were no impending revisions at the most recent follow-up. We did not detect periacetabular osteolysis or loosening on plain radiographs in those hips that were evaluated radiographically (n = 90; 83% of the hips available at a minimum of 10 years). Kaplan-Meier survival analysis using revision of the acetabular component for any reason (including isolated inlay revisions) as endpoint estimated the 11-year survival rate at 98% (95% CI: 92–99). Interpretation Uncemented acetabular fixation using the Allofit press-fit cup without additional screws was excellent into early in the second decade in this young and active patient cohort. The rate of complications related to the liner and to osteolysis was low. PMID:24875058

    Purpose To determine the amount and time course of binocular visual acuity improvement during treatment of bilateral refractive amblyopia in children age 3 to <10 years old Design Prospective, multicenter noncomparative intervention Methods 113 children (mean age = 5.1 years) with previously untreated bilateral refractive amblyopia were enrolled at 27 community- and university-based sites and were provided optimal spectacle correction. Bilateral refractive amblyopia was defined as 20/40 to 20/400 best-corrected binocular acuity in the presence of ≥ 4.00 D hypermetropia by spherical equivalent and/or ≥ 2.00 D astigmatism in each eye. Best-corrected binocular and monocular visual acuities were measured at baseline and at 5, 13, 26 and 52 weeks. The primary study outcome was binocular acuity at one year. Results Mean binocular visual acuity improved from 0.50 logMAR (20/63) at baseline to 0.11 logMAR (20/25) at one year (mean improvement 3.9 lines, 95% confidence interval [CI] = 3.5 to 4.2). Mean improvement at one year for the 84 children with baseline binocular acuity of 20/40 to 20/80 was 3.4 lines (95% CI = 3.2 to 3.7) and for the 16 children with baseline binocular acuity of 20/100 to 20/320 was 6.3 lines (95% CI = 5.1 to 7.5). The cumulative probability of binocular acuity of 20/25 or better was 21% at 5 weeks, 46% at 13 weeks, 59% at 26 weeks, and 74% at 52 weeks. Conclusions Treatment of bilateral refractive amblyopia with spectacle correction improves binocular visual acuity in children age 3 to <10 years old, with most improving to 20/25 or better within one year.

    The restoration of ecosystem services, i.e., production, regulation, and information, is a global challenge, which the federal state of Mecklenburg-Vorpommern in NE Germany addressed in 2000 by rewetting over 20,000 ha of degraded peatlands within the Mire Restoration Program. We evaluated ecosystem services in 23 rewetted sites by assessing the following mire parameters within a ten year period: (a) dominant vegetation at the ecosystem level, (b) peat formation potential at the landscape level, and (c) aboveground biomass and nutrient levels. Seven to 10 years after rewetting, the wetlands formed a mosaic of vegetation types with the highest potential for peat formation and several dominant, peat-forming species accumulated high levels of aboveground biomass and nutrients (C, N, P). Common reed (Phragmites australis) accumulated the most biomass (up to 24 t dry matter/ha), and N+P during the growing season. A future management option is to annually harvest aquatic and wetland plants to reduce nutrient levels in restored mire ecosystems.

    Long-term measurements of nitrous oxide (N2O) obtained during the Atmospheric Lifetime Experiment (ALE) and the Global Atmospheric Gases Experiment (GAGE) for a period from 1978 to 1988 are presented and interpreted. It is observed that the average concentration in the Northern Hemisphere is 0.75 +/- 0.16 ppbv higher than in the Southern Hemisphere and that the global average linear trend in N2O lies in the range from 0.25 to 0.31 percent/year. The measured trends and latitudinal distributions are shown to be consistent with the hypothesis that stratospheric photodissociation is the major atmospheric sink for N2O, while the cause of the N2O trend is suggested to be a combination of a growing tropical source and a growing Northern mid-latitude source. A 10-year average global N2O emission rate of (20.5 +/- 2.4) x 10 to the 12th g N2O/year is deduced from the ALE/GAGE data.

    Leprosy control measures adopted in Bombay consist of health education, case-detection, and treatment, and are carried out mainly by the Acworth Leprosy Hospital and its subsidiary, the Greater Bombay Leprosy Control Scheme. Although the data collected on different aspects of leprosy during the 10-year period 1963-72 are hospital-based and retrospective, their analysis provides a useful indicator of the possible situation in the field. Health education is provided by medical social workers, field staff, and physicians, and the significance of this activity in relation to early detection of leprosy is analysed. It is shown, however, that case-holding is a more urgent priority than case-detection. Trials have confirmed the effectiveness of chemoprophylaxis with dapsone for contacts of infectious index cases in crowded households. Comparison of annual expenditure per outpatient in leprosy clinics with that for inpatients in a leprosy hospital demonstrates greater cost-effectiveness of outpatient treatment. Some practical recommendations are made for leprosy control. PMID:827341

    The restoration of ecosystem services, i.e., production, regulation, and information, is a global challenge, which the federal state of Mecklenburg-Vorpommern in NE Germany addressed in 2000 by rewetting over 20,000 ha of degraded peatlands within the Mire Restoration Program. We evaluated ecosystem services in 23 rewetted sites by assessing the following mire parameters within a ten year period: (a) dominant vegetation at the ecosystem level, (b) peat formation potential at the landscape level, and (c) aboveground biomass and nutrient levels. Seven to 10 years after rewetting, the wetlands formed a mosaic of vegetation types with the highest potential for peat formation and several dominant, peat-forming species accumulated high levels of aboveground biomass and nutrients (C, N, P). Common reed ( Phragmites australis) accumulated the most biomass (up to 24 t dry matter/ha), and N+P during the growing season. A future management option is to annually harvest aquatic and wetland plants to reduce nutrient levels in restored mire ecosystems.

    Serum transferrin receptor (sTfR) originates mostly from erythroblasts and lesser from reticulocytes. The usefulness of sTfR has been implicated in several clinical situations, mainly as a marker of accelerated erythropoiesis or iron deficiency. The assessment of sTfR may be useful in the period of rapid growth during infancy, childhood and adolescence. We evaluated sTfR and the other quantitative and qualitative parameters of the erythropoiesis (Hb, MCV, CHr, Ret-He) and of the iron storage (serum ferritin, sTfR/ferritin index) in a total of 916 children aged 6-10 years. Children were divided into three groups: (A) healthy children, (B) with storage iron deficiency (serum ferritin < 12 microg/l) and (C) Beta trait carriers (HbA2 > 3.3). We determined reference intervals by sex and by age in healthy children. sTfR showed a slight but statistically significant age related increase but did not show significant sex differences. We compared sTfR and the other parameters investigated in the three groups of children. sTfR is not a decisive parameter that can be utilized alone in discriminating the border-line situations between normal and pathologic ones but can help in completing the panel of tests in iron deficiency and in thalassaemia Beta trait carriers.

    The purpose of the current study was to conduct a 10-year systematic review of HIV/AIDS mass communication campaigns focused on sexual behavior, HIV testing, or both (1998-2007) and to compare the results with the last comprehensive review of such campaigns, conducted by Myhre and Flora (2000). A comprehensive search strategy yielded 38 HIV/AIDS campaign evaluation articles published in peer-reviewed journals, representing 34 distinct campaign efforts conducted in 23 countries. The articles were coded on a variety of campaign design and evaluation dimensions by two independent coders. Results indicated that compared with the previous systematic review (1986-1998 period), campaigns increasingly have employed the following strategies: (1) targeted defined audiences developed through audience segmentation procedures; (2) designed campaign themes around behavior change (rather than knowledge change); (3) used behavioral theories; (4) achieved high message exposure; (5) used stronger research designs for outcome evaluation; and (6) included measures of behavior (or behavioral intentions) in outcome assessments. In addition, an examination of 10 campaign efforts that used more rigorous quasi-experimental designs revealed that the majority (8 of 10) demonstrated effects on behavior change or behavioral intentions. Despite these positive developments, most HIV/AIDS campaigns continue to use weak (i.e., preexperimental) outcome evaluation designs. Implications of these results for improved design, implementation, and evaluation of HIV/AIDS campaign efforts are discussed.

    An 18-year-old male patient was referred to the department of pediatric pulmonology with a history of recurrent pneumothorax. Initial pneumothorax occurred at the age of 10. Following diagnosis of congenital lobar emphysema, he had five episodes of pneumothorax and subsequently underwent right-lower lobe anterobasal segmentectomy. Based on thoracic computed tomography (CT) and clinical manifestation, Birt-Hogg-Dube (BHD) syndrome was suspected and confirmed following genetic testing. BHD syndrome is a rare tumor predisposition syndrome first described in 1977. The syndrome is characterized by skin fibrofolliculomas, lung cysts, recurrent spontaneous pneumothorax, and renal cell cancer. The underlying cause is a germline mutation in the folliculin (FLCN) gene located on chromosome 17p11.2. Clinical manifestation usually appears after the age of 20 years. In this case, we report a case of BHD with episodes of recurrent pneumothorax, the first of which occurred at the age of 10 years. Pulmonologists should be aware of this syndrome in patients with a personal and family history of pneumothoraces and CT findings of multiple pulmonary cysts as additional evaluation and testing may be warranted.

    A single surgeon's consecutive series of 50 arthroscopically repaired meniscal tears in 48 patients was retrospectively reviewed. None of these patients had concomitant ligament damage to the knee. The average follow-up period was 10 years, 9 months. Criteria for clinical success included 1) history of pain of grade 1 or less and absence of locking, catching, or giving way; 2) a physical examination demonstrating no significant effusion and a painless and negative jump sign; and 3) no subsequent surgical procedures on the repaired meniscus. Patient satisfaction was quite high, although clinical confirmation was possible in only 38 knees, indicating a clinical success rate of 76%. Bilateral standing radiographs were obtained on these 38 operated knees and were evaluated using Fairbank's classification. Evaluation of the radiographs revealed that 8% of the operated knees had minimal joint changes, as compared with 3% in the contralateral, nonoperated knee. This study demonstrates that arthroscopic meniscal repair in knees with isolated meniscal tears has the potential for a long-term successful clinical and radiographic outcome.

    The aim of this study was to examine fire-related injuries leading to inpatient care in Finland. The Finnish National Hospital Discharge Register (2000-2009) and a sample of 222 patients from the Helsinki Burn Centre who sustained flame burns was used. During the 10-years study period, the incidence of fire-related injuries with inpatient care was approximately 5.6 per 100000 persons-years (n=295; males 74%, females 26%). Approximately three quarters involved burns and the remaining cases were mostly combustion gas poisonings. Burns declined from 5.4 in 2000 to 4.0 per 100000 person-years in 2009. The decline was accounted for by young people primarily. Socio-economic features and smoking habits differ between the injured and general population. House fire victims were mainly middle aged and older, while injures involving flammable substances, campfires, etc., were mostly associated with young people. House fires caused the worst damage in terms of Total Body Surface Area burned and inhalation burns. Significantly more people die on the scene of the incident than during the hospital care. Targeting preventive measures in particular at older people and those with a tendency for alcohol abuse and smoking could potentially reduce the burden of the most severe flame burns.

    Purpose This study was performed to review the outcomes of gastrostomy insertion in children at our institute during 10 years. Methods A retrospective chart review was performed on 236 patients who underwent gastrostomy insertion from October 2005 to March 2015. We used our algorithm to select the least invasive method for gastrostomy insertion for each patient. Long-term follow-up was performed to analyze complications related to the method of gastrostomy insertion. Results Out of 236 patients, 120 underwent endoscopic gastrostomy, 79 had laparoscopic gastrostomy, and 37 had open gastrostomy procedures. The total major complication rates for endoscopic gastrostomy insertion, laparoscopic gastrostomy insertion, and open gastrostomy were 9.2%, 8.9%, and 8.1%, respectively. The most common major complication was gastroesophageal reflux requiring Nissen fundoplication (3.8%), and other complications included peritonitis (1.3%), hiatal hernia (1.3%), and bowel perforation (0.8%). Gastrostomy removal was successful in 8.6% and 5.0% of patients in the endoscopic and surgical gastrostomy groups, respectively. Gastrocutaneous fistula occurred in 60% of surgically inserted cases, requiring a second operation. Conclusion This retrospective study was performed to review the outcome of gastrostomy insertion, as well as to introduce an algorithm that can be used for future cases. Further studies should be conducted to make a consensus on choosing the most appropriate method for gastrostomy insertion.

  7. Preconditioning based on Calderon's formulae for periodic fast multipole methods for Helmholtz' equation

    2012-01-01

    Solution of periodic boundary value problems is of interest in various branches of science and engineering such as optics, electromagnetics and mechanics. In our previous studies we have developed a periodic fast multipole method (FMM) as a fast solver of wave problems in periodic domains. It has been found, however, that the convergence of the iterative solvers for linear equations slows down when the solutions show anomalies related to the periodicity of the problems. In this paper, we propose preconditioning schemes based on Calderon's formulae to accelerate convergence of iterative solvers in the periodic FMM for Helmholtz' equations. The proposed preconditioners can be implemented more easily than conventional ones. We present several numerical examples to test the performance of the proposed preconditioners. We show that the effectiveness of these preconditioners is definite even near anomalies.

    Over the past 10 years in the U.S., dam removal has evolved from an occasionally implemented, rarely studied, and poorly understood intervention to improve rivers, to a much more frequently accomplished and better studied and understood approach to river restoration. Over that same time period, the numbers and sizes of dams and volumes of sediment released have dramatically increased. By some estimates close to 1000 dams have been removed over the last 100 years, with most of those occurring within the last 10. While most of these are small (less than 15 m high) dams, removals of dams up to 70 m high are presently underway. Releases of sediment associated with these removals over the past 10 years have also increased by close to four orders of magnitude; for example removal of the Elwha River dams in Washington is estimated to release almost 107 m3 of sediment into the lower Elwha River. Given a decade's worth of dam removals and, in some cases, well-orchestrated case studies of the effects of removal on the geomorphology and (to a lesser extent) ecology of rivers, what have we learned? More specifically, where do we now stand with respect to being able to predict the consequences of future dam removals? Drawing on both field examples and numerical models of dam removals in the western U.S., several key lessons stand out. Although every dam removal and river are different, removals initiate very rapid upstream river response and reservoir erosion and evacuation of sediment by various mechanisms that are strongly controlled by grain size of the deposit, volumes of residual sediment relative to total reservoir volume, and style of dam removal (instantaneous versus staged). Erosion of sediment accumulations in fully and partially filled (by sediment) reservoirs proceeds by different trajectories and rates, with full reservoirs releasing sediment primarily by upstream knickpoint retreat while erosion and sediment release in partially-filled reservoirs proceeds by

    We present a detailed description of the methods used in our model of mode instability in high-power, rare earth-doped, large-mode-area fiber amplifiers. Our model assumes steady-periodic behavior, so it is appropriate to operation after turn on transients have dissipated. It can be adapted to transient cases as well. We describe our algorithm, which includes propagation of the signal field by fast-Fourier transforms, steady-state solutions of the laser gain equations, and two methods of solving the time-dependent heat equation: alternating-direction-implicit integration, and the Green's function method for steady-periodic heating.

    To evaluate the accuracy and long-term stability of the SAO OMI ozone profile product, we validate ~10 years of ozone profile product (Oct. 2004-Dec. 2014) against collocated ozonesonde and MLS data. Ozone profiles as well stratospheric, tropospheric, lower tropospheric ozone columns are compared with ozonesonde data for different latitude bands, and time periods (e.g., 2004-2008/2009-2014 for without/with row anomaly. The mean biases and their standard deviations are also assessed as a function of time to evaluate the long-term stability and bias trends. In the mid-latitude and tropical regions, OMI generally shows good agreement with ozonesonde observations. The mean ozone profile biases are generally within 6% with up to 30% standard deviations. The biases of stratospheric ozone columns (SOC) and tropospheric ozone columns (TOC) are -0.3%-2.2% and -0.2%-3%, while standard deviations are 3.9%-5.8% and 14.4%-16.0%, respectively. However, the retrievals during 2009-2014 show larger standard deviations and larger temporal variations; the standard deviations increase by ~5% in the troposphere and ~2% in the stratosphere. Retrieval biases at individual levels in the stratosphere and upper troposphere show statistically significant trends and different trends for 2004-2008 and 2009-2014 periods. The trends in integrated ozone partial columns are less significant due to cancellation from various layers, except for significant trend in tropical SOC. These results suggest the need to perform time dependent radiometric calibration to maintain the long-term stability of this product. Similarly, we are comparing the OMI stratospheric ozone profiles and SOC with collocated MLS data, and the results will be reported.

    Objectives Little research has investigated the role of migration as a potential contributor to the spatial concentration of homeless people with complex health and social needs. In addition, little is known concerning the relationship between possible migration and changes in levels of service use over time. We hypothesised that homeless, mentally ill individuals living in a concentrated urban setting had migrated from elsewhere over a 10-year period, in association with significant increases in the use of public services. Setting Recruitment was concentrated in the Downtown Eastside neighbourhood of Vancouver, Canada. Participants Participants (n=433) met criteria for chronic homelessness and serious mental illness, and provided consent to access administrative data. Methods Linked administrative data were used to retrospectively examine geographic relocation as well as rates of health, justice, and social welfare service utilisation in each of the 10 years prior to recruitment. Generalised estimating equations were used to estimate the effect of migration on service use. Results Over a 10-year period there was significant movement into Vancouver's Downtown Eastside neighbourhood (from 17% to 52% of the cohort). During the same period, there were significant annual increases in community medical services (adjusted rate ratio (ARR) per year=1.08; 95% CI 1.06 to 1.10), hospital admissions (ARR=1.08; 95% CI 1.04 to 1.11), criminal convictions (ARR=1.08; 95% CI 1.03 to 1.13), and financial assistance payments (ARR=1.04; 95% CI 1.03 to 1.06). Migration was significantly associated with financial assistance, but not with other types of services. Conclusions Significant increases in service use over a 10-year period coincided with significant migration into an urban area where relevant services were concentrated. These results highlight opportunities for early intervention in spatially diverse neighbourhoods to interrupt trajectories marked by worsening health and

    Multiple signal classification (MUSIC) algorithms are introduced to the estimation of the period of variation of BL Lac objects.The principle of MUSIC spectral analysis method and theoretical analysis of the resolution of frequency spectrum using analog signals are included. From a lot of literatures, we have collected a lot of effective observation data of BL Lac object S5 0716 + 714 in V, R, I bands from 1994 to 2008. The light variation periods of S5 0716 +714 are obtained by means of the MUSIC spectral analysis method and periodogram spectral analysis method. There exist two major periods: (3.33±0.08) years and (1.24±0.01) years for all bands. The estimation of the period of variation of the algorithm based on the MUSIC spectral analysis method is compared with that of the algorithm based on the periodogram spectral analysis method. It is a super-resolution algorithm with small data length, and could be used to detect the period of variation of weak signals.

    A method of detecting and correcting received values of a pitch period estimate of a speech signal for use in a speech coder or the like. An average is calculated of the nonzero values of received pitch period estimate since the previous reset. If a current pitch period estimate is within a range of 0.75 to 1.25 times the average, it is assumed correct, while if not, a correction process is carried out. If correction is required successively for more than a preset number of times, which will most likely occur when the speaker changes, the average is discarded and a new average calculated.

    Background: Oral-facial clefts including cleft lip and palate are the most common congenital malformations of the head and neck. Environmental factors such as maternal hormonal disorders, use of psychiatric medications, vitamin and folic acid deficiency, hypoxia, cigarette smoking and maternal obesity and overweight can affect the incidence of these disorders. In Iran, one of the associated problems is a lack of accurate statistics regarding the present status of the patients, which can cause a disturbance in the health programmes of Ministry of Health and Medical Education. The aim of this study was to report the status of 398 cases of cleft lip and palate in Sheikh and Imam Reza Hospitals of Mashhad over a 10-year period. Materials and Methods: This retrospective descriptive study was performed using data collection method and included the evaluation of the recorded files and completing the data forms. In this study, the file records of 398 patients referring to Mashhad Sheikh and Imam Reza (P.U.H) Hospitals were studied, from the beginning of 2002 to the end of 2011; the obtained data from the files were collected and classified. Results: The highest frequency was related to cleft palate alone (40.7%); frequencies were lower regarding the cleft lip and palate and cleft lip alone (34.41% and 24.87%, respectively). Approximately, half of the patients were from rural areas of the city and had articulation disorders. Most of the patients were the first-born children of the family and their parents were consanguineously married; about one-third of the patients had a family history of the disease. Conclusion: According to the results of the present study, cleft lip is more frequent in males and cleft palate is more prevalent in females; the obtained results are consistent with the global statistics.

  18. Dual-component model of respiratory motion based on the periodic autoregressive moving average (periodic ARMA) method

    NASA Astrophysics Data System (ADS)

    McCall, K. C.; Jeraj, R.

    2007-07-01

    A new approach to the problem of modelling and predicting respiration motion has been implemented. This is a dual-component model, which describes the respiration motion as a non-periodic time series superimposed onto a periodic waveform. A periodic autoregressive moving average algorithm has been used to define a mathematical model of the periodic and non-periodic components of the respiration motion. The periodic components of the motion were found by projecting multiple inhale-exhale cycles onto a common subspace. The component of the respiration signal that is left after removing this periodicity is a partially autocorrelated time series and was modelled as an autoregressive moving average (ARMA) process. The accuracy of the periodic ARMA model with respect to fluctuation in amplitude and variation in length of cycles has been assessed. A respiration phantom was developed to simulate the inter-cycle variations seen in free-breathing and coached respiration patterns. At ±14% variability in cycle length and maximum amplitude of motion, the prediction errors were 4.8% of the total motion extent for a 0.5 s ahead prediction, and 9.4% at 1.0 s lag. The prediction errors increased to 11.6% at 0.5 s and 21.6% at 1.0 s when the respiration pattern had ±34% variations in both these parameters. Our results have shown that the accuracy of the periodic ARMA model is more strongly dependent on the variations in cycle length than the amplitude of the respiration cycles.

    Management of water resources, implying their appropriate protection, calls for a sound evaluation of recharge. Such assessment is very complex in karst aquifers. Most methods are developed for application to detrital aquifers, without taking into account the extraordinary heterogeneity of porosity and permeability of karst systems. It is commonly recommended to estimate recharge using multiple methods; however, differences inherent to the diverse methods make it difficult to clarify the accuracy of each result. In this study, recharge was estimated in a karst aquifer working in a natural regime, in a Mediterranean-type climate, in the western part of the Sierra de las Nieves (southern Spain). Mediterranean climate regions are characterized by high inter-annual rainfall variability featuring long dry periods and short intense wet periods, the latter constituting the most important contribution to aquifer water input. This paper aims to identify the methods that provide the most plausible range of recharge rate during wet periods. Six methods were tested: the classical method of Thornthwaite-Mather, the Visual Balan code, the chloride balance method, and spatially distributed methods such as APLIS, a novel spatiotemporal estimation of recharge, and ZOODRM. The results help determine valid methods for application in the rest of the unit of study and in similar karst aquifers.

    Objective: The present study had been undertaken to investigate the sociodemographic profile of individuals who had committed suicide in Sikkim which may throw light on the vulnerable groups. Materials and Methods: Ten-year suicide data (2006–2015) obtained from Police Headquarters, Crime Branch, Gangtok, have been statistically evaluated to study the sociodemographic profile. Results: The results showed that out of 1604 suicide cases recorded for the past 10 years, 1051 were males (65.5%) and 553 (34.5%) were females. Suicide was found to be common among the age group of 21–30 years (24.4%), Rai community (15.8%), population of rural areas (82.6%), and among the population of eastern districts (50.6%). Hanging (94.8%) was found to be the most common method adopted for suicide. Conclusion: The study provides preliminary information about the vulnerable groups for suicide in the state which may be vital for taking necessary steps for its prevention shortly. PMID:28197004

    Objective Identifying personality disorder (PD) risk factors for suicide attempts is an important consideration for research and clinical care alike. However, most prior research has focused on single PDs or categorical PD diagnoses without considering unique influences of different PDs, or severity (sum) of PD criteria on the risk for suicide related outcomes. This has usually been done in cross-sectional or retrospective assessment methods. Rarely are dimensional models of PDs examined in longitudinal, naturalistic prospective designs. In addition, it is important to consider divergent risk factors in predicting the risk of ever making a suicide attempt versus making an increasing number of attempts within the same model. Method This study examined 431 participants who were followed for 10 years in the Collaborative Longitudinal Personality Disorders Study (CLPS). Baseline assessments of personality disorder criteria were summed as dimensional counts of personality pathology and examined as predictors of suicide attempts reported at annual interviews throughout the ten-year follow-up. We employed univariate and multivariate zero-inflated Poisson regression models to simultaneously evaluate PD risk factors for ‘ever attempt’ and for increasing numbers of attempts among attempters. Results Consistent with prior research, borderline PD was uniquely associated with ever attempting. However, only narcissistic PD was uniquely associated with an increasing number of attempts. Conclusion These findings highlight the relevance of both borderline and narcissistic personality pathology as unique contributors to suicide related outcomes. PMID:25705977

  2. An Improved Isotropic Periodic Sum Method That Uses Linear Combinations of Basis Potentials.

    Isotropic periodic sum (IPS) is a technique that calculates long-range interactions differently than conventional lattice sum methods. The difference between IPS and lattice sum methods lies in the shape and distribution of remote images for long-range interaction calculations. The images used in lattice sum calculations are identical to those generated from periodic boundary conditions and are discretely positioned at lattice points in space. The images for IPS calculations are "imaginary", which means they do not explicitly exist in a simulation system and are distributed isotropically and periodically around each particle. Two different versions of the original IPS method exist. The IPSn method is applied to calculations for point charges, whereas the IPSp method calculates polar molecules. However, both IPSn and IPSp have their advantages and disadvantages in simulating bulk water or water-vapor interfacial systems. In bulk water systems, the cutoff radius effect of IPSn strongly affects the configuration, whereas IPSp does not provide adequate estimations of water-vapor interfacial systems unless very long cutoff radii are used. To extend the applicability of the IPS technique, an improved IPS method, which has better accuracy in both homogeneous and heterogeneous systems has been developed and named the linear-combination-based isotropic periodic sum (LIPS) method. This improved IPS method uses linear combinations of basis potentials. We performed molecular dynamics (MD) simulations of bulk water and water-vapor interfacial systems to evaluate the accuracy of the LIPS method. For bulk water systems, the LIPS method has better accuracy than IPSn in estimating thermodynamic and configurational properties without the countercharge assumption, which is used for IPSp. For water-vapor interfacial systems, LIPS has better accuracy than IPSp and properly estimates thermodynamic and configurational properties. In conclusion, the LIPS method can successfully estimate

    Background Serum lipid trends in children and adolescents are predictors of the future prevalence of cardiovascular disease in adults. Methods Data were obtained from cross-sectional studies conducted in 2004 and 2014. A total of 3249 children aged 6–18 years were included in the present study; serum total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and triglycerides (TG) were measured. Results Overall, upward trends in mean TC, non-HDL-C, and LDL-C levels, and in geometric mean TG levels, were observed (all P < 0.001). Mean HDL-C levels significantly decreased between 2004 and 2014 (from 1.54 mmol/L to 1.47 mmol/L; P < 0.001). The prevalence of abnormal levels of serum lipids, with the exception of the prevalence of low HDL-C (P = 0.503), significantly increased over the study period (all P < 0.05). The prevalence of hyperlipidemia (from 13.3%; 95% confidence interval [CI], 11.6%–15.0% to 24.5%; 95% CI, 22.4%–26.6%; P < 0.001) and dyslipidemia (from 18.8%; 95% CI, 16.9%–20.7% to 28.9%; 95% CI, 26.7%–31.3%; P < 0.001) also increased from 2004 to 2014. The prevalence of abnormal serum lipids increased, and mean serum lipid levels, with the exception of TC levels, worsened in subjects with obesity compared with non-overweight subjects, as well as in subjects with mixed obesity compared with non-obese subjects (P < 0.05 for all). Conclusions Adverse trends in serum lipid concentrations over the past 10 years were observed among children aged 6–9 years, with the exception of specific lipids, and among adolescents aged 10–18 years, from several schools in Beijing, China.

    Objective: Prospective analysis of the prevalence of symptoms, tolerability and complications associated with ureteral stents and their impact on quality of life based on the Flanagan Quality of Life Scale and a not-validated questionnaire from our clinic. Methods: A total of 2200 adult patient participated to this study in a period of 10 years (2003-2012). Those patients were asked to complete the QOLS and a not-validated questionnaire from our clinic, before ureteral indwelling, 7 day after ureteral indwelling and 14 days after removal of the stent. Results: Total 1520 patient aged between 18 and 84 years completed the study. The analysis of data showed that the unpleasant symptoms caused by stent were encountered more frequently at 7 days after stent insertion, in terms of urinary frequency, dysuria, urgency and macroscopic haematuria, this difference being statistically significant (p<0.05). After analysis the responses to QOLS questionnaire, at 7 days after stent placement, mean scores show a clear reduction in the QoL of those patients, in all cases the standard deviation being at a great value, indicating a high variability of responses, but at 14 days after its suppression of stent the average scores are somewhat closer to the baseline. Conclusions: Our study brings many elements that shows a statistically significant increase in the incidence of numerous side effects and impaired quality of life. It contributes to existing data from the literature as regards the knowledge of the pathology determined by the presence of foreign body in the urinary tract and in providing patient counseling.

    Background Accurate patient identification and specimen labeling at the time of collection are crucial steps in the prevention of medical errors, thereby improving patient safety. Methods All patient specimen identification errors that occurred in the outpatient department (OPD), emergency department (ED), and inpatient department (IPD) of a 3,800-bed academic medical center in Taiwan were documented and analyzed retrospectively from 2005 to 2014. To reduce such errors, the following series of strategies were implemented: a restrictive specimen acceptance policy for the ED and IPD in 2006; a computer-assisted barcode positive patient identification system for the ED and IPD in 2007 and 2010, and automated sample labeling combined with electronic identification systems introduced to the OPD in 2009. Results Of the 2000345 specimens collected in 2005, 1023 (0.0511%) were identified as having patient identification errors, compared with 58 errors (0.0015%) among 3761238 specimens collected in 2014, after serial interventions; this represents a 97% relative reduction. The total number (rate) of institutional identification errors contributed from the ED, IPD, and OPD over a 10-year period were 423 (0.1058%), 556 (0.0587%), and 44 (0.0067%) errors before the interventions, and 3 (0.0007%), 52 (0.0045%) and 3 (0.0001%) after interventions, representing relative 99%, 92% and 98% reductions, respectively. Conclusions Accurate patient identification is a challenge of patient safety in different health settings. The data collected in our study indicate that a restrictive specimen acceptance policy, computer-generated positive identification systems, and interdisciplinary cooperation can significantly reduce patient identification errors.

    Purpose: To assess the intermediate clinical outcomes of medically inoperable patients with endometrial cancer treated with definitive Rotte 'Y' applicator high-dose-rate brachytherapy (HDRB) over a 10-year period. Methods and Materials: Forty-nine inoperable patients were treated with HDRB from 1997 to 2007. Forty three (84%) were markedly obese (body mass index >35 kg/m{sup 2}). Thirty-one patients (63.3%) underwent two-dimensional treatment planning, whereas 18 patients (36.7%) underwent three-dimensional treatment planning. Thirty five of the patients (71.4%) were first treated with external beam radiotherapy (EBRT). For patients receiving EBRT in addition to HDRB, the median Y-applicator dose was 20 Gy in 5 fractions; for patients receiving HDRB alone it was 35 Gy in 5 fractions. All patients received two Y-applicator treatments per day. Results: Median follow-up time for all patients was 33 months. Acute HDRB toxicities were limited to Grade 1 and 2 occurring in 5 patients. One patient had a myocardial infarction. Four patients had late Grade 2 or 3 toxicity. Three patients had local recurrence (median time to recurrence, 16 months). The 3- and 5-year actuarial cause-specific survival rates were 93% and 87%, respectively; the overall survival rate was 83% and 42%, respectively, at 3 and 5 years. Conclusions: Twice-daily HDRB using a Y-applicator is a well-tolerated and efficacious regimen for the definitive treatment of medically inoperable patients with early-stage endometrial cancer. The recent incorporation of three-dimensional treatment planning has the potential to further decrease treatment morbidities.

    Live attenuated varicella vaccine (Oka strain, Biken Institute, Osaka, Japan) was administered to 973 healthy individuals over a 10-year period (1987-1997) at the pediatric clinic of Showa Hospital in Japan. We evaluated the relevant serological and clinical data, which were collected by questionnaire. Seroconversion by the immune adherence hemagglutination method was documented in 94% (805/860) of the initially seronegative subjects. Of the initially seropositive subjects, 56% (63/113) showed enhancement of antibody after vaccination. Reactions to the vaccine were generally insignificant, except for a rash at the injection site, seen in the first 3 days post-administration in 17% (41/241) of the recently vaccinated subjects. In March 1998, we conducted a survey of 559 of the initially seronegative subjects who had received the vaccine 0.6-10. 8 (mean 5.4) years earlier. Of these subjects, 21% (119/559) contracted breakthrough varicella. However, their symptoms were milder than those caused by natural varicella seen in unvaccinated children. Seroconversion was demonstrated in 92% (109/119) of these cases. The incidence of breakthrough disease decreased with a rise in postvaccination antibody titer to >==32. Four of the subjects (0.7% of 559) developed herpes zoster following vaccination, two of whom had earlier exhibited breakthrough varicella. Lesions in one case of zoster, without breakthrough varicella, appeared on the cervical dermatome at the injection site. The vaccine was safe and effective. However, there was a relatively high incidence of rash at the injection site with certain lot numbers used in recent years which warrants investigation.

    The authors report their experience with orbital exenteration surgery at one academic institution over a 10-year period and review the literature. This retrospective cohort study monitored outcomes of all patients who underwent orbital exenteration surgery at Massachusetts Eye and Ear Infirmary between January 2003 and January 2013. Patients with no follow-up data or survival data were excluded from the study. The main outcome measures were surgical complications, disease status of surgical margins, need for adjuvant treatment, local recurrence, metastases and survival. 23 patients with malignancy and 2 with mucormycosis met inclusion criteria for the study. Surgical procedures included non-lid sparing total exenteration (44%), lid-sparing total exenteration (32%), non-lid sparing partial exenteration (8%) and lid-sparing partial exenteration (16%). 44% underwent additional extra-orbital procedures. Survival rates were 72% at 1 year, 48% at 3 years, and 37% at 5 years. Of patients with malignancies, 48% had clear margins after exenteration. There was no statistically significant difference in survival between patients with negative surgical margins compared to positive margins (p = 0.12). Mortality was highest in patients with melanoma (85.7%) and lowest in patients with non-squamous cell lid malignancies (0%). Our study suggests that the type of disease has a much greater impact on the survival of patients undergoing exenteration surgery than the type of exenteration surgery or the disease status of surgical margins. Patients with non-squamous cell lid malignancies and localized orbital disease have the best prognosis for tumor eradication from this radical and highly disfiguring surgery.

    Oseltamivir (Tamiflu®; F. Hoffmann-La Roche Ltd, Basel, Switzerland) is an orally administered antiviral for the treatment and prevention of influenza A and B infections that is registered in more than 100 countries worldwide. More than 83 million patients have been exposed to the product since its introduction. Oseltamivir is recommended by the World Health Organization (WHO) for use in the clinical management of pandemic and seasonal influenza of varying severity, and as the primary antiviral agent for treatment of avian H5N1 influenza infection in humans. This article is a nonsystematic review of the experience gained from the first 10 years of using oseltamivir for influenza infections since its launch in early 2000, emphasizing recent advances in our understanding of the product and its clinical utility in five main areas. The article reviews the pharmacokinetics of oseltamivir and its active metabolite, oseltamivir carboxylate, including information on special populations such as children and elderly adults, and the co-administration of oseltamivir with other agents. This is followed by a summary of data on the effectiveness of oseltamivir treatment and prophylaxis in patients with all types of influenza, including pandemic (H1N1) 2009 and avian H5N1 influenza. The implications of changes in susceptibility of circulating influenza viruses to oseltamivir and other antiviral agents are also described, as is the emergence of antiviral resistance during and after the 2009 pandemic. The fourth main section deals with the safety profile of oseltamivir in standard and special patient populations, and reviews spontaneously reported adverse event data from the pandemic and pre-pandemic periods and the topical issue of neuropsychiatric adverse events. Finally, the article considers the pharmacoeconomics of oseltamivir in comparison with vaccination and usual care regimens, and as a component of pandemic influenza mitigation strategies.

    Since the beginning of the cholera epidemic in Haiti 5 years ago, the prevalence of this deadly water-borne disease has fallen far below the initial rates registered during its explosive outset. However, cholera continues to cause extensive suffering and needless deaths across the country, particularly among the poor. The urgent need to eliminate transmission of cholera persists: compared to the same period in 2014, the first 4 months of 2015 saw three times the number of cholera cases. Drawing upon epidemiology, clinical work (and clinical knowledge), policy, ecology, and political economy, and informed by ethnographic data collected in a rural area of Haiti called Bocozel, this paper evaluates the progress of the nation's 10-year Plan for the Elimination of Cholera. Bocozel is a rice-producing region where most people live in extreme poverty. The irrigation network is decrepit, the land is prone to environmental shocks, fertilizer is not affordable, and the government's capacity to assist farmers is undermined by resource constraints. When peasants do have rice to sell, the price of domestically grown rice is twice that of US-imported rice. Canal water is not only used to irrigate thousands of acres of rice paddies and sustain livestock, but also to bathe, wash, and play, while water from wells, hand pumps, and the river is used for drinking, cooking, and bathing. Only one out of the three government-sponsored water treatment stations in the research area is still functional and utilized by those who can afford it. Latrines are scarce and often shared by up to 30 people; open defecation remains common. Structural vulnerabilities cut across all sectors - not just water, sanitation, health care, and education, but agriculture, environment, (global and local) commerce, transportation, and governance as well. These are among the hidden sicknesses that impede Haiti and its partners' capacity to eliminate cholera.

    Legislative and regulatory mandates have resulted in reduced sulfur dioxide (SO2) emissions in both the eastern and western United States with anticipation that concurrent levels of ambient SO2, SO42-, and rainwater acidity would decrease. This paper examines spatial and temporal trends in ambient SO42- concentration from 1988 to 1999, SO2 emissions from 1990 to 1999, and the relationship between these two variables. The SO42- concentration data came from combining data from the Interagency Monitoring of Protected Visual Environments (IMPROVE) and the Clean Air Status and Trends Network (CASTNet). Over 70 sites spread across the continental United States are considered in this analysis. From a spatial perspective, the 90th percentile summer sulfate concentrations are highest along the Ohio River Valley and in central Tennessee where the emission density of SO2 is greatest. These concentrations are a factor of 2 greater than the Northeast, northern Michigan, and coastal areas of the Southeast and about a factor of 15 greater than the central western United States. In the East, the largest SO42- decreases in the 80th percentile concentrations occurred north of the Ohio River Valley, while most monitoring sites south of Kentucky and Virginia showed increasing and decreasing trends that were not statistically significant. Big Bend National Park, Texas, Cranberry, North Carolina, and Lassen Volcanic National Park, California, are the only areas that show a statistically significant increase in SO42- mass concentrations. The 1990-1999 annual 80th percentile SO42- time series were compared to the annual SO2 emissions over four broad United States regions. Each region had a unique time series pattern with the SO42- concentrations and SO2 emissions closely tracking each other over the 10-year period. Both the SO42- and SO2 emissions decreased in the Northeast (28%) and the West (15%), while there was little change in the Southeast and a 15% increase over Texas, New Mexico

    Objective To describe a 10-year proof-of-concept smoking cessation research program evaluating the reach of online health interventions throughout the Americas. Methods Recruitment occurred from 2002–2011, primarily using Google.com AdWords. Over 6 million smokers from the Americas entered keywords related to smoking cessation; 57 882 smokers (15 912 English speakers and 41 970 Spanish speakers) were recruited into online self-help automated intervention studies. To examine disparities in utilization of methods to quit smoking, cessation aids used by English speakers and Spanish speakers were compared. To determine whether online interventions reduce disparities, abstinence rates were also compared. Finally, the reach of the intervention was illustrated for three large Spanish-speaking countries of the Americas—Argentina, Mexico, and Peru—and the United States of America. Results Few participants had utilized other methods to stop smoking before coming to the Internet site; most reported using no previous smoking cessation aids: 69.2% of Spanish speakers versus 51.8% of English speakers (P < 0.01). The most used method was nicotine gum, 13.9%. Nicotine dependence levels were similar to those reported for in-person smoking cessation trials. Overall observed quit rate for English speakers was 38.1% and for Spanish speakers, 37.0%; quit rates in which participants with missing data were considered to be smoking were 11.1% and 10.6%, respectively. Neither comparison was significantly different. Conclusions The systematic use of evidence-based Internet interventions for health problems could have a broad impact throughout the Americas, at little or no cost to individuals or to ministries of health.

    We present a new method to identify semi-periodic sequences in the occurrence times of large earthquakes, which allows for the presence of multiple semi-periodic sequences and/or events not belonging to any identifiable sequence in the time series. The method, based on the analytic Fourier transform, yields estimates of the departure from periodicity of an observed sequence, and of the probability that the sequence is not due to chance. These estimates are used to make and to evaluate forecasts of future events belonging to each sequence. Numerous tests with synthetic catalogs show that the method is surprisingly capable of correctly identifying sequences, unidentifiable by eye, in complicated time series. Correct identification of a given sequence depends on the number of events it contains, on the sequence's departure from periodicity, and, in some cases, on the choice of starting and ending times of the analyzed time window; as well as on the total number of events in the time series. Some particular data combinations may result in spectra where significant periods are obscured by large amplitudes artifacts of the transform, but artifacts can be usually recognized because they lack harmonics; thus, in most of these cases, true semi-periodic sequences may not be identified, but no false identifications will be made. A first example of an application of the method to real seismicity data is the analysis of the Parkfield event series. The analysis correctly aftcasts the September 2004 earthquake. Further applications to real data from Japan and Venezuela are shown in a companion paper.

  16. The paediatric flat foot and general anthropometry in 140 Australian school children aged 7 - 10 years

    2011-01-01

    Background Many studies have found a positive relationship between increased body weight and flat foot posture in children. Methods From a study population of 140 children aged seven to 10 years, a sample of 31 children with flat feet was identified by screening with the FPI-6. Basic anthropometric measures were compared between subjects with and without flat feet as designated. Results The results of this study, in contrast to many others, question the association of flat feet and heavy children. A significant relationship between foot posture and weight (FPI (L) r = -0.186 (p < 0.05), FPI(R) r = -0.194 (p < 0.05), waist girth (FPI (L) r = -0.213 (p < 0.05), FPI(R) r = -0.228 (p < 0.01) and BMI (FPI (L) r = -0.243 (p < 0.01), FPI(R) r = -0.263 (p < 0.01) was identified, but was both weak and inverse. Conclusions This study presents results which conflict with those of many previous investigations addressing the relationship between children's weight and foot posture. In contrast to previous studies, the implication of these results is that heavy children have less flat feet. Further investigation is warranted using a standardized approach to assessment and a larger sample of children to test this apparent contradiction. PMID:21513507

    ABSTRACT Background and Objective: Skull base chordomas are clinically malignant because of the difficulty of total removal, high recurrence rate, and occasional drop metastasis. Although aggressive surgical resection and postoperative radiation have been recommended, the long-term outcome remains unsatisfactory. Methods: From 1992 to 2011, we treated 24 patients with skull base chordoma using aggressive surgical removal as a principal strategy. Skull base approaches were selected according to tumor extension to remove the tumor and surrounding bone as completely as possible. After surgery, all patients were closely observed with MRI to find small and localized recurrent tumors, which were treated with gamma-knife radiosurgery or surgical resection. The mean postoperative follow-up duration was 10.2 years (range, 1-17.2 years). Results: The 5-, 10-, and 15-year overall survival rates were 86%, 72%, and 72%, respectively. The 5- and 10-year progression-free survival rates were 47% and 35%, respectively. Tumor extension to the brainstem and partial tumor removal were the factors related to poor survival. Conclusions: Our results suggest that aggressive surgical removal improves the long-term outcome of patients with skull base chordoma. We would like to emphasize that skull base chordomas should be aggressively removed using various skull base approaches. PMID:26370681

    The objective of this study was to create a computer-aided design (CAD) geometric dataset of a 10-year-old (10 YO) child. The study includes two phases of efforts. At Phase One, the 10 YO whole body CAD was developed from component computed tomography and magnetic resonance imaging scans of 12 pediatric subjects. Geometrical scaling methods were used to convert all component parts to the average size for a 10 YO child, based on available anthropometric data. Then the component surfaces were compiled and integrated into a complete body. The bony structures and flesh were adjusted as symmetrical to minimize the bias from a single subject while maintaining anthropometrical measurements. Internal organs including the liver, spleen, and kidney were further verified by literature data. At Phase Two, internal characteristics for the cervical spine disc, wrist, hand, pelvis, femur, and tibia were verified with data measured from additional 94 10 YO children. The CAD dataset developed through these processes was mostly within the corridor of one standard deviation (SD) of the mean. In conclusion, a geometric dataset for an average size 10 YO child was created. The dataset serves as a foundation to develop computational 10 YO whole body models for enhanced pediatric injury prevention.

    The method of empirical orthogonal functions (EOF) was applied to a 10-year data set of outgoing longwave radiation. Spherical harmonic functions are used as a basis set for producing equal area map results. The following findings are noted. The first EOF accounts for 66 percent of the variance. After that, each EOF accounts for only a small variance, forming a slowly converging series. The first two EOF's describe mainly the annual cycle. The third EOF is primarily the semiannual cycle although many other EOF's also contain significant semiannual parts. These results reaffirm those based on a shorter data set. In addition, a much stronger spring/fall mode was found in the central equatorial Pacific Ocean for the second EOF than was found earlier. This difference is attributed to the use of broadband radiometer data which were available for the present study. The earlier study used data from a window channel instrument which is not as sensitive to water vapor variations. The fourth EOF describes much of the 1976 to 1977 and 1982 to 1983 ENSO phenomena. There is typically a gap in the spectrum between a semiannual peak and the annual cycle for all but the first EOF. A semiannual OLR dipole straddles the Asian-Australian monsoon track.

    Background Central obesity is a major risk factor for diabetes but many obese individuals never develop diabetes, suggesting the presence of important effect modifiers. Depression has emerged as a key risk factor for poor glycemic control, but to our knowledge, no previous work has investigated whether depression amplifies the effect of central obesity on glucoregulation. Methods and Findings We used a national sample of adults without prevalent diabetes (MIDUS; N = 919) to test for synergy between central obesity and depression in the development of diabetes 10 years later. We found that depression amplified the association of waist-to-hip ratio (WHR) with incident diabetes adjusted for age, race, gender, education, physical activity, and sleep problems (p = 0.01 for test of interaction). The relative risk for incident diabetes per every 0.1 increment in WHR was 1.75 (95% CI: 1.31; 2.33) in those without depression and 3.78 in those with depression (95% CI: 2.14; 6.66). Conclusions These results confirm the role of depression as a robust risk factor for the development of diabetes and for the first time, demonstrate a synergy between depression and central obesity. Identifying and addressing depression could prove to be an effective approach to preventing diabetes in at risk individuals. Ultimately, elucidating the interplay among risk factors from different domains will be key to understanding multifactorial diseases such as diabetes and informing theory-based, patient-centered interventions aimed at reducing diabetes risk.

    Background: Although the overwhelming majority of Iranian adolescents are well-adjusted, a substantial group exhibits high levels of maladjustment and deficient functioning. Escalation of criminal violence among the youth population has become a major public policy issue and a serious public health problem. In reviewing a 10-year literature, this article aimed to describe and propose primary assumptions regarding the correlates of aggressive and violent behaviors in Iranian adolescents and youth. Methods: Bibliographic databases such as PubMed and Google Scholar along with Iranian databases including PubMed, IranMedex, Magiran, Irandoc, Psychoinfo, and Emrofor Scientific Information Database, and Magiran constituted the databases which we searched for the relevant literature. Overall 98 articles met the inclusion criteria, allowing us to initiate the discussion. Results: Reportedly, prevalence of violence and aggression among the Iranian adolescents and youth ranged from 30% to 65.5% while males being 2½ times more affected than females. The role of gender, family environment, family size, socioeconomic status, and victimization in perpetuating the circumstances was apparent. Conclusions: Relatively high prevalence of violence and aggression among Iranian youth and adolescents is a warning sign and a great challenge to the social system. Reviewed studies suffer from certain methodological and conceptual limitations. Undertaking community-based studies to estimate the actual extent of the problem is warranted. PMID:26157572

    BACKGROUND Preventing obesity is a worldwide public health priority. In vulnerable children living in obesogenic environments, with easy access to high-caloric food, alterations in inhibitory control functions might favor excessive food intake and affect energy regulation. We hypothesized that overweight/obese children would present lower inhibitory control in comparison to normal weight children. METHODS We measured inhibitory control functions in 93 otherwise healthy overweight/obese and 92 normal weight 10-year-old children using the Stroop test and the Go/No-Go task. Event-related potentials were recorded during the Go/No-Go task. RESULTS Overweight/obese children showed slower reaction times (1248.6 ms (95% confidence interval (CI): 1182.9–1314.3) vs 1149.0 ms (95% CI: 1083.0–1215.1)) on the Stroop test, higher reaction time variability (0.25 (95% CI: 0.22–0.27) vs 0.21 (95% CI: 0.19–0.24)) on the Go/No-Go task and decreased P300 amplitude (4.1 µV (95% CI: 3.0–5.2) vs 6.4 µV (95% CI: 5.2–7.6)) on event-related potentials compared with normal weight children. CONCLUSIONS Our results indicate altered inhibitory control functions in otherwise healthy overweight/obese children, which might contribute to their excessive food consumption. PMID:25869603

  8. A general method for the existence of periodic solutions of differential systems in the plane

    NASA Astrophysics Data System (ADS)

    Fonda, Alessandro; Sfecci, Andrea

    We propose a general method to prove the existence of periodic solutions for planar systems of ordinary differential equations, which can be used in many different circumstances. Applications are given to some nonresonant cases, even for systems with superlinear growth in some direction, or with a singularity. Systems "at resonance" are also considered, provided a Landesman-Lazer type of condition is assumed.

    2007-12-01

    Ab initio studies of one-dimensionally periodic systems are advantageously carried out by methods that employ Fourier representations and the Ewald method for accelerating the lattice sums. This communication desribes the first investigation in which these techniques have been applied at the Mo/ller-Plesset level of perturbation theory, MBPT(2). Second-order corrections to the restricted Hartree-Fock energy and energy bands are reported for H2, Be, and LiH chains, and these results are compared to direct-space extended-system and oligomer computations. The methods described herein exhibit improved convergence relative to the other methods to which they are compared.

    1992-01-01

    A novel method of electric field flow fractionation for separating solute molecules from a carrier solution is disclosed. The method of the invention utilizes an electric field that is periodically reversed in polarity, in a time-dependent, wave-like manner. The parameters of the waveform, including amplitude, frequency and wave shape may be varied to optimize separation of solute species. The waveform may further include discontinuities to enhance separation.

    2015-01-01

    Objective Cross-sectional studies support that bisexual and gay (BG) men are at increased risk for eating pathology, and romantic relationships may buffer against risk; however, no studies have examined this association longitudinally. The current study examined how romantic relationships impact the trajectory of eating pathology in BG versus heterosexual men. Method BG (n=51) and heterosexual (n=522) men completed surveys of health and eating behaviors at baseline and 10-year follow-up. Results For BG men, being single at baseline prospectively predicted an increase in Drive for Thinness scores over 10-year follow-up. Additionally, for BG men in relationships at baseline, lower relationship satisfaction predicted an increase in Drive for Thinness scores over time. Conversely, these relationship variables did not predict trajectory of eating pathology for heterosexual men. Discussion Implications for theoretical models of risk, including objectification theory and sexual minority stress theory, and prevention, including peer-led cognitive dissonance based interventions, are discussed.

  12. Estimating the length of waits: a description of the period lifetable method and comparison with census and event based methods.

    PubMed

    Armstrong, Paul W

    2012-05-01

    To discover whether the period lifetable provides more valid estimates of length of wait in prospect than are obtained using the lengths either of (current) waits captured at the time of the mid-period census or of the (prior) waits of those extracted over a specified period. We determined whether there was a surplus (or a deficiency) of extractions within the cross-classification of cohort and waiting time category which straddled each census. We used census-, event- and lifetable-based methods to produce three period-specific estimates of the percentage of waits of 0-2 months, and we determined whether length of wait grew shorter (or longer) from one period to the next. We used Lambda B to indicate the extent to which we were able to predict the direction of change in length of wait once we knew the direction of change in size of list. We found a direct correlation between change in length of wait and change in size of list, as expected under the stock-flow model, when length of wait was estimated using the lifetable for the period (L(B) = 58.33, 95% confidence interval [CI] = 29-88), but we obtained a null correlation when we used census-based estimates (L(B) = 6.45) and we obtained an inverse correlation when we used event-based estimates (L(B) = 57.14, 95% CI = 31-83). The period lifetable appears to provide more valid estimates of length of wait and should therefore be substituted for census- and event-based methods of estimation, wherever possible.

  13. Comparative analysis of computational methods for periodic transonic flows at low and high frequencies

    NASA Astrophysics Data System (ADS)

    Mohaghegh, M. R.; Malek-Jafarian, M.

    2015-12-01

    This paper presents a comparative analysis via simulation of time-periodic unsteady inviscid flow at low and high frequencies using Time Spectral Method (TSM) and comparing it with the traditional methods such as BDF and Explicit Structured Adaptive Grid Method. The TSM uses a Fourier representation in time. Mathematical tools used here are discrete Fourier transformations. The TSM has been proposed for the fast and efficient computation of periodic unsteady flows. This method has been evaluated and has been validated with NACA pitching airfoils that are widely used and prevalent 2D external aerodynamics test cases. To validate the results presented by the TSM are compared with experimental data and two the other methods. It shows a significant reduction in the computational expense compared to the conventional time-accurate methods, due to taking advantage of the periodic nature of flow by Fourier representation for temporal discretization that has a high accuracy. Also it has shown that TSM can be applied accurately for ample rang of variations of frequency (NACA 64A010 (CT6)) and variations in angle of attacks (NACA 0012 (CT1)).

  14. High-Fidelity Generalization Method of Cells for Inelastic Periodic Multiphase Materials

    NASA Technical Reports Server (NTRS)

    2002-01-01

    An extension of a recently-developed linear thermoelastic theory for multiphase periodic materials is presented which admits inelastic behavior of the constituent phases. The extended theory is capable of accurately estimating both the effective inelastic response of a periodic multiphase composite and the local stress and strain fields in the individual phases. The model is presently limited to materials characterized by constituent phases that are continuous in one direction, but arbitrarily distributed within the repeating unit cell which characterizes the material's periodic microstructure. The model's analytical framework is based on the homogenization technique for periodic media, but the method of solution for the local displacement and stress fields borrows concepts previously employed by the authors in constructing the higher-order theory for functionally graded materials, in contrast with the standard finite-element solution method typically used in conjunction with the homogenization technique. The present approach produces a closed-form macroscopic constitutive equation for a periodic multiphase material valid for both uniaxial and multiaxial loading. The model's predictive accuracy in generating both the effective inelastic stress-strain response and the local stress said inelastic strain fields is demonstrated by comparison with the results of an analytical inelastic solution for the axisymmetric and axial shear response of a unidirectional composite based on the concentric cylinder model, and with finite-element results for transverse loading.

  15. Ciguatera fish poisoning in Hong Kong--a 10-year perspective on the class of ciguatoxins.

    PubMed

    2014-08-01

    The present study used liquid chromatography-tandem mass spectrometry (LC-MS/MS) to investigate retrospectively ciguatoxin (CTX)-positive samples as determined by mouse bioassay (MBA) in the past 10 years in Hong Kong. The results showed that Pacific CTXs (P-CTX-1, -2 and -3) were the most commonly observed toxins found in the samples, indicating Pacific Ocean areas as the most important origin of ciguatera fish poisoning. Clinical diagnosis from ciguatera patients also revealed the predominance of neurological illnesses in most cases, supporting intoxication of Pacific origin. This study demonstrated the ability of laboratory analysis to identify and quantify Pacific CTXs in suspected fish samples, so as to support the clinical diagnosis of ciguatera. Comparative analysis (Student's t-test and Spearman's rank correlation analysis) on the two CTX detection methods showed approximate linearity for overall P-CTXs (P-CTX-1, -2 and -3)/P-CTX-1 alone as derived by LC-MS/MS and total toxicity levels (P-CTX-1 equivalent) as determined by MBA. The LC-MS/MS method coupled with the rapid extraction method could allow the detection of trace amount of CTXs at levels below the clinically relevant limit, 0.1 ppb P-CTX-1 in fish flesh. For practical application, the adoption of a two-tiered approach for testing, chemical analysis by LC-MS/MS for toxic fish screening, coupled with biological assay by MBA for final toxicity confirmation, was proposed for first-line screening of CTX in potentially contaminated fish samples in the market, with an aim to minimizing the use of laboratory mice and at the same time providing reasonably effective means for routine analysis.

    Background & Aims Guidelines recommend a 10 year interval between screening colonoscopies with negative results for average-risk individuals. However, many patients are examined at shorter intervals. We investigated outcomes of individuals with no polyps who had repeat colonoscopy in less than 10 years. Methods Data were collected using the National Endoscopic Database, from 69 gastroenterology centers, on 264,184 asymptomatic subjects who underwent screening colonoscopies from 2000 through 2006, were found to have no polyps, and received another colonoscopy examination within less than 10 years. Results No polyps were found in 147,375 patients during a baseline colonoscopy; 17,525 patients (11.9%) had a follow-up colonoscopy within less than 10 years, including 1806 (10.3%) who received the follow-up colonoscopy within less than 1 year. The most common reason for repeating the examination within 1 year was that the first was compromised by inadequate bowel preparation or incomplete examination. Of these patients, 6.5% (95% confidence interval [CI], 5.3–7.6) had large polyp(s) >9 mm—a proportion similar to the prevalence in the average-risk screening population. Reasons that examinations were repeated within 1–5 years included average-risk screening (15.7%), family history of colon polyps or cancer (30.1%), bleeding (31.2%), gastrointestinal symptoms (11.8%), or a positive result from a fecal blood test (5.5%). If the baseline exam was adequate, the incidence of large polyps within 1–5 years after baseline colonoscopy was 3.1% (95% CI, 2.7–3.5) and within years 5–10 years was 3.7% (95% CI, 3.3–4.1). Conclusions Repeat colonoscopies within 10 years are of no benefit to patients who had adequate examinations and were found to have no polyps. Repeat colonoscopies are beneficial to patients when the baseline examination was compromised. PMID:24768680

  17. Split-field FDTD method for oblique incidence study of periodic dispersive metallic structures.

    PubMed

    Baida, F I; Belkhir, A

    2009-08-15

    The study of periodic structures illuminated by a normally incident plane wave is a simple task that can be numerically simulated by the finite-difference time-domain (FDTD) method. On the contrary, for off-normal incidence, a widely modified algorithm must be developed in order to bypass the frequency dependence appearing in the periodic boundary conditions. After recently implementing this FDTD algorithm for pure dielectric materials, we here extend it to the study of metallic structures where dispersion can be described by analytical models. The accuracy of our code is demonstrated through comparisons with already-published results in the case of 1D and 3D structures.

  18. Periodic equivalence ratio modulation method and apparatus for controlling combustion instability

    Richards, George A.; Janus, Michael C.; Griffith, Richard A.

    2000-01-01

    The periodic equivalence ratio modulation (PERM) method and apparatus significantly reduces and/or eliminates unstable conditions within a combustion chamber. The method involves modulating the equivalence ratio for the combustion device, such that the combustion device periodically operates outside of an identified unstable oscillation region. The equivalence ratio is modulated between preselected reference points, according to the shape of the oscillation region and operating parameters of the system. Preferably, the equivalence ratio is modulated from a first stable condition to a second stable condition, and, alternatively, the equivalence ratio is modulated from a stable condition to an unstable condition. The method is further applicable to multi-nozzle combustor designs, whereby individual nozzles are alternately modulated from stable to unstable conditions. Periodic equivalence ratio modulation (PERM) is accomplished by active control involving periodic, low frequency fuel modulation, whereby low frequency fuel pulses are injected into the main fuel delivery. Importantly, the fuel pulses are injected at a rate so as not to affect the desired time-average equivalence ratio for the combustion device.

    Purpose. To retrospectively evaluate the 10 year follow-up results in patients who had 'kissing' self-expanding stent aortic bifurcation reconstruction. Methods. Forty-three patients were treated with 'kissing' self-expanding stents for aortoiliac occlusive disease. Early follow-up with clinical and ankle brachial pressure indices (ABPI) was performed at 3, 6, 12, and 24 months and with intra-arterial digital subtraction angiography at 12-24 months; clinical and angiographic follow-up was performed for symptom recurrence up to 10 years after treatment. Retrospective record review was performed to assess mortality, clinical patency, angiographic patency, and secondary assisted patency of both stents and downstream peripheral vessels at 5 and 10 years follow-up. Results. The 2 year primary angiographic and secondary assisted stent patencies were 89% and 93%, respectively. At 10 years follow-up in 40 patients the mortality was 38% (due to myocardial infarction, stroke, chronic renal failure, malignancy, and liver failure). At 5 and 10 years follow-up the primary clinical stent patency was 82% and 68%, and the secondary assisted stent patency 93% and 86%, respectively. At 5 and 10 years, the distal vessel patency was 86% and 72%, and the secondary assisted distal vessel patency treated by surgical or endovascular techniques was 94% and 88%, respectively. At 10 years there was no limb loss. Conclusion. The long-term (10 year) results of aortic bifurcation arterial self-expanding stent placement in patients with arterial occlusive disease show a 10 year primary stent patency rate of 68% but a secondary assisted patency rate of 86%. In addition there is a high overall mortality due to other cardiovascular causes and the rate of distal disease progression and loss of patency is similar to the loss of stent patency rate.

  20. Continuation of quasi-periodic solutions with two-frequency Harmonic Balance Method

    NASA Astrophysics Data System (ADS)

    Guillot, Louis; Vigué, Pierre; Vergez, Christophe; Cochelin, Bruno

    2017-04-01

    The continuation of quasi-periodic solutions for autonomous or forced nonlinear systems is presented in this paper. The association of the Asymptotic Numerical Method, a robust continuation method, and a two-frequency Harmonic Balance Method, is performed thanks to a quadratic formalism. There is no need for a priori knowledge of the solution: the two pulsations can be unknown and can vary along the solution branch, and the double Fourier series are computed without needing a harmonic selection. A norm criterion on Fourier coefficients can confirm a posteriori the accuracy of the solution branch. On a forced system, frequency-locking regions are approximated, without blocking the continuation process. The continuation of these periodic solutions can be done independently. On an autonomous system an example of solution is shown where the number of Fourier coefficients is increased to improve the accuracy of the solution.

  1. Sheepskin effects of education in the 10-year Framingham risk of coronary heart disease.

    While the association between education and adult health is well documented, it is unclear whether quantity (i.e. years of schooling) or credentials (i.e. degrees) drive this association. Individuals with degrees may have better health than their non-credentialed counterparts given similar years of schooling, the so-called "sheepskin" effect. This paper contributes to this line of inquiry by examining associations of educational degree and years of schooling with the Framingham Risk Score, a measure of 10-year risk of coronary heart disease (CHD), using data from a unique birth cohort (the New England Family Study; participants mean age 42 years) with prospective information on childhood health and intelligence quotient (IQ). According to our results, years of schooling were inversely associated with 10-year CHD risk in the unadjusted model but not in the fully adjusted models that included degree attainment. By contrast, associations between degree attainment and 10-year CHD risk remained significant in the fully adjusted models that included years of schooling. College degree holders had 10-year CHD risk 19% (95% CI: -33%, -2%) lower than individuals with HS degrees or less in the fully adjusted models. Subanalyses evaluating sheepskin effects on the individual components of the 10-year CHD risk algorithm showed the expected education gradient was generally noted for each of the individual components, with decreasing prevalence of "high risk" values associated with higher degree credentials. Our results suggest educational credentials provide an additional benefit to risk of coronary heart disease beyond schooling.

    2010-08-01

    We consider a method for calculating forced oscillations in nonlinear discrete-time systems under periodic external actions. The method is based on representing the stationary oscillations in the form of an invariant set of nonlinear discrete point mappings and allows one to calculate the nonlinear-system response in the steady-state regime. The examples of using this method for calculating forced oscillations in the first- and second-order nonlinear recursive systems under the harmonic-signal action on such systems are presented.

    2014-11-18

    A Monte Carlo method is applied for modeling of a plasma source with a periodic structure of a radiofrequency electric field. The method is modified in order to detect resonance increase of the electron energy at given velocities of the electrons as expected from theoretical considerations. The numerical model is validated by comparison with known analytical results. The applicability of the method for detection of resonance velocities in plasma sources with electric field variation parallel or perpendicular to the electric field vector is proven.

    2014-03-01

    The transition from adolescence to adulthood has been shown to be a time of amplified risk for individuals with autism spectrum disorders (ASD). It is unknown, however, whether problems in educational attainment and employment in the years after high school exit represent momentary perturbations in development or a turning point with long-lasting effects throughout adulthood. The present study addressed this question by examining 10-year trajectories of vocational and educational activities for adults with ASD, as well as the personal characteristics and environmental resources that predicted these activities. Participants were 161 adults with ASD (ages 18-52 years at the start of the study; M = 30.9) who were part of a larger longitudinal study. Data were collected at 6 time points over a 10-year period. Results indicated significant declines in the level of independence and engagement in vocational/educational activities over the study period, particularly for women. Greater independence in vocational activities was found for those with more independence in activities of daily living. After controlling for personal characteristics, receipt of more services was marginally related to greater improvement in vocational independence.

    Background Evaluations of large-scale health and nutrition programmes in developing countries are needed for determining the effectiveness of interventions. This article critically analyses a non-governmental organization (NGO)-led large-scale, multi-country, 10-year micronutrient and health (MICAH) programme with an ‘adequacy evaluation’, that is, a documentation of time trends in the expected direction. Methods MICAH was implemented from 1996 to 2005 in selected areas of Ethiopia, Ghana, Malawi and Tanzania, reaching >6 million people with numerous health and nutrition interventions. Coverage and impact were monitored through surveys at baseline, midpoint and end of funding. The data were subjected to post-hoc methods of quality determination, and, if of suitable quality, included in the adequacy evaluation. Results Most collected data were of moderate or high quality and therefore included in the adequacy evaluation. There were moderate to large improvements in vitamin A status in Ethiopian school-age children, children <5 years of age in Tanzania and Ghana and mothers in Ghana. Iodine status improved in Malawi and Tanzania. Anaemia rates and malaria prevalence decreased in women, pregnant women and pre-school children in Ghana, Malawi and Tanzania, but anaemia increased in Ethiopian women. Large increases were reported for rates of exclusive breastfeeding and immunization. Child growth improved to the maximum that would be predicted with the given interventions. Conclusions Numerous nutrition and health impacts were observed in the intervention areas, often of a magnitude equal to or larger than observed in controlled interventions or trials. These results show the value of integrated long-term interventions. PMID:20202929

    2002-02-01

    The principles of the United Nations Conference on Environment and Development (UNCED), held in June 1992 in Rio de Janeiro, and Agenda 21, the comprehensive plan of action for the 21st century, adopted 10 years ago by more than 170 governments, address the pressing problems of today and also aim at preparing the world for the challenges of this century. The conservation and management of resources for development are the main focus of interest, to which the sciences will have to make a considerable contribution. Natural, economic, and social sciences will have to be integrated in order to achieve this aim. In their future programs, the associations of the chemical industries in Europe, Japan, and the USA have explicitly accepted their obligation to foster a sustainable development. In this review we investigate innovations in chemistry exemplarily for such a development with regard to their ecological, economical, and social dimensions from an integrated and interdisciplinary perspective. Since base chemicals are produced in large quantities and important product lines are synthesized from them, their resource-saving production is especially important for a sustainable development. This concept has been shown, amongst others, by the example of the syntheses of propylene oxide and adipic acid. In the long run, renewable resources that are catalytically processed could replace fossil raw materials. Separation methods existing today must be improved considerably to lower material and energy consumption. Chemistry might become the pioneer of an innovative energy technique. The design of chemical products should make possible a sustainable processing and recycling and should prevent their bio-accumulation. Methods and criteria to assess their contribution to a sustainable development are necessary. The time taken to introduce the new more sustainable processes and products has to be diminished by linking their development with operational innovation management and with

    Introduction Provision of oral health knowledge to the children by their teachers at the school level can prove to be more fruitful because it is the time period during which the children begin to learn the basic oral hygiene practices and are most prone to dental caries. Aim This study was carried out to assess the effect of training school teachers on oral hygiene status of 8-10 years old government school children of Udaipur city, India. Materials and Methods A total of nine school teachers and 279, 8-10 year old school children from two government schools were included in the study. The questionnaire on oral health knowledge and practice contained 17 questions to evaluate the knowledge and practice of children towards oral hygiene before and after the teachers training program. Baseline and six months post training data on oral health knowledge and practice was obtained by the questionnaire method. Baseline and six months post training data on oral hygiene status was obtained by OHI-S Index. Statistical analysis was done using software SPSS 22, the test used were McNemar’s test, paired t-test. Results Pre and post training data were compared and it was found that there was a significant improvement in oral health knowledge and practices of school teachers and children. Also oral hygiene status of school children was significantly improved after the program. Conclusion Results of the present study suggest that experiential learning is an effective school based oral health education method for improvement of oral hygiene in primary school children.

    Density functional theory (DFT) at the generalised gradient approximation level is employed within the periodic electrostatic embedded cluster method (PEECM) to model the brucite (0001) surface. Three representative studies are then used to demonstrate the reliability of the PEECM for the description of the interactions of various ionic species with the layered Mg(OH)2 structure, and its performance is compared with periodic DFT, an approach known to be challenging for the adsorption of charged species. The adsorption energies of a series of s block cations, including Sr2+ and Cs+ which are known to coexist with brucite in nuclear waste storage ponds, are well described by the embedded cluster model, provided that basis sets of triple-zeta quality are employed for the adsorbates. The substitution energies of Ca2+ and Sr2+ into brucite obtained with the PEECM are very similar to periodic DFT results, and comparison of the approaches indicates that two brucite layers in the quantum mechanical part of the PEECM are sufficient to describe the substitution. Finally, a detailed comparison of the periodic and PEECM DFT approaches to the energetic and geometric properties of differently coordinated Sr[(OH)2(H2O)4] complexes on brucite shows an excellent agreement in adsorption energies, Sr-O distances, and bond critical point electron densities (obtained via the quantum theory of atoms-in-molecules), demonstrating that the PEECM can be a useful alternative to periodic DFT in these situations.

    Dispositional optimism may be associated with growth of social and status resources by virtue of optimists' greater persistence and better performance. Conversely, resource growth may give people a more positive view of their future and increase optimism. Changes in dispositional optimism and resources over 10 years were examined in former law students (N = 61). More optimistic first-year law students made more money 10 years later, but income did not predict later optimism. More optimistic students did not have larger social networks 10 years later, but increases in social network size predicted increased optimism. These changes predicted mental and physical health. Dispositional optimism was less stable than many personality traits (r = .35), potentially because it is responsive to resource change. PMID:24347739

    As the incidence of measles decreases, cases reported as suspected measles will increasingly involve rash associated with measles vaccination itself. In this study, we assessed vaccine-associated measles cases reported in Korea between 2002 and 2012 using a standardized assessment and following by the World Health Organization case definition criteria. We retrospectively analyzed data regarding (i) wild-type measles and (ii) vaccine-associated measles in patients aged 12-23 months. The presence or absence of fever, rash, cough, coryza, conjunctivitis, and Koplik spots were reviewed. Males were more likely to be reported with vaccine-associated measles than with wild-type measles (68% vs. 47%, P < 0.05). The number of patients with wild-type measles peaked between April and July, whereas that of patients with vaccine-associated measles remained relatively constant throughout the year. However, after excluding the cases reported during the 2007 outbreak in Korea, the trend was similar between the two groups. Cough, coryza, and conjunctivitis were more likely to be present in patients with wild-type measles (32-61% vs. 10-43%, P < 0.05); conversely, the absence of these symptoms was noted in most patients with vaccine-associated measles. We therefore conclude that cough, coryza, and conjunctivitis may be useful as key positive findings to distinguish between wild-type measles and vaccine-associated measles infection among 12-23-month-old patients in a country with a low incidence of measles.

    Violence against women has many negative consequences. In this short report the authors investigate patterns of mortality among women experiencing violence leading to inpatient care from 1992 to 2006. Do women who are victims of severe violence have an increased mortality risk (a) in general? (b) by violence? (c) by suicide? Does socioeconomic position have any bearing on the mortality risk? The study was based on Swedish national registers, where 6,085 women exposed to violence resulting in inpatient care were compared with a nonexposed population sample of 55,016 women. Women of all social strata previously exposed to severe violence and treated in hospital had a highly increased risk of premature death from all-cause mortality, violence, or suicide. Women previously exposed to severe violence continue to live a life in danger. There is need for a societal response to support and protect these women against further violence after discharge from hospital.

    In recent years, there are numerous reports indicating the presence of familial papillary carcinoma. Unfortunately, no genetic defect can be linked directly to the disease. In this study, we set the goal to make a retrospective analysis of the cases with papillary carcinoma in the Department of Endocrine Surgery for the past 10 years, to compare the characteristics of sporadic and familial forms of the disease and to find families with hereditary papillary carcinoma. The study included 810 patients treated for thyroid cancer in the Department of Endocrine Surgery, USBALE "Acad. Iv. Penchev" Hospital, between January 1, 2006 and December 31, 2015. We used chi square test to determine statistical significant difference. The data analysis and interpretation was performed on SPSS 20.0. Both groups had similar demographic distribution. We found that 587 patients have sporadic papillary carcinoma, while 147 have a relative with thyroid pathology in the first degree of kinship. In 8 patients, there was a blood relative with thyroid cancer. When we compared the two groups, we found statistically significant difference only in tumor size. There was no significant difference in aggressiveness of the thyroid cancer (multifocality and lymph node metastasis). When analyzing the results, we identified 147 patients with a family history of thyroid disease (20%). In 8 patients (5.44%), we found at least one relative with papillary thyroid carcinoma. However, our study does not demonstrate any difference in the aggressiveness of familial and sporadic papillary thyroid carcinoma.

    Abstract The purposes of this study were to assess the prevalence, malignancy rate, and characteristics of incidental thyroid nodules (ITNs), and to identify factors that contribute the additional workup by ultrasound. The medical records and imaging features of ITNs reported via thoracic computed tomography (CT) were retrospectively reviewed to determine the size, multiplicity, attenuation, shape, and presence of calcification. To identify the factors associated with additional workup, we compared the workup and non-workup groups in terms of nodule characteristics, indications, and CT slices. We identified factors that could distinguish malignant ITNs from non-malignant nodules. A total of 60,921 thoracic CT scans met the inclusion criteria, and ITNs were reported using formal radiology in 2733 patients (4.5%). Among all patients with reported ITNs, 546 (20.0%) underwent further workup. Of these patients, 62 (2.3%, 62/2773) were diagnosed with malignant nodules. Multivariable analysis identified multiple factors associated with additional workup, including female sex, younger age, larger nodule size, calcification, anteroposterior to transverse dimension ratio >1, heterogeneous attenuation in the nodule, and scanning indications such as infection or screening. However, only calcification was associated with malignant nodules (odds ratio [OR] = 2.313; 95% confidence interval [CI], 1.301–4.113). We observed discordance between the numbers of reported ITNs and case with additional workup and identified multiple factors associated with additional workup. We have, therefore, demonstrated a need for reliable subsequent evaluation guidelines and note that the appearance of calcification in an ITN on imaging may be a factor indicating the need for additional workup.

    The fine periodic growth patterns on shell surfaces have been widely used for studies in the ecology and evolution of scallops. Modern X-ray CT scanners and digital cameras can provide high-resolution image data that contain abundant information such as the shell formation rate, ontogenetic age, and life span of shellfish organisms. We introduced a novel multiscale image processing method based on matched filters with Gaussian kernels and partial differential equation (PDE) multiscale hierarchical decomposition to segment the small tubular and periodic structures in scallop shell images. The periodic patterns of structures (consisting of bifurcation points, crossover points of the rings and ribs, and the connected lines) could be found by our Space-based Depth-First Search (SDFS) algorithm. We created a MATLAB package to implement our method of periodic pattern extraction and pattern matching on the CT and digital scallop images available in this study. The results confirmed the hypothesis that the shell cyclic structure patterns encompass genetically specific information that can be used as an effective invariable biomarker for biological individual recognition. The package is available with a quick-start guide and includes three examples: http://mgb.ouc.edu.cn/novegene/html/code.php.

    Aims: We formulate an improved time series analysis method for the analysis of photometry of active stars. This new continuous period search (CPS) method is applied to 12 years of V band photometry of the young solar analogue HD 116956 (NQ UMa). Methods: The new method is developed from the previous three stage period analysis (TSPA) method. Our improvements are the use of a sliding window in choosing the modelled datasets, a criterion applied to select the best model for each dataset and the computation of the time scale of change of the light curve. We test the performance of CPS with simulated and real data. Results: The CPS has a much improved time resolution which allows us to better investigate fast evolution of stellar light curves. We can also separate between the cases when the data is best described by periodic (i.e. rotational modulation of brightness) and aperiodic (e.g. constant brightness) models. We find, however, that the performance of the CPS has certain limitations. It does not determine the correct model complexity in all cases, especially when the underlying light curve is constant and the number of observations too small. Also the sensitivity in detecting two close light curve minima is limited and it has a certain amount of intrinsic instability in its period estimation. Using the CPS, we find persistent active longitudes in the star HD 116956 and a "flip-flop" event that occurred during the year 1999. Assuming that the surface differential rotation of the star causes observable period variations in the stellar light curve, we determine the differential rotation coefficient to be |k| > 0.11. The mean timescale of change of the light curve during the whole 12 year observing period was overline{TC=44.1} d, which is of the same order as the predicted convective turnover time of the star. We also investigate the presence of activity cycles on the star, but do not find any conclusive evidence supporting them. The analysed photometry and numerical

    This paper presents a level set-based topology optimization method for noise barriers formed from an assembly of scatterers. The scattering obstacles are modeled by elastic bodies arranged periodically along the wall. Due to the periodicity, the problem can be reduced to that in a unit cell. The interaction between the elastic scatterers and the acoustic field is described in the context of the level set analysis. The semi-infinite acoustic wave regions located on the both sides of the barrier are represented by impedance matrices. The objective function is defined by the energy transmission passing the barrier. The design sensitivity is evaluated analytically by the aid of adjoint equations. The dependency of the optimal profile on the stiffness of scatterers and on the target frequency band is examined. The feasibility of the developed optimization method is proved through numerical examples.

    The need for antennas with improved characteristics for communication and radar applications has resulted in an ever-increasing demand for research in the field of high impedance surfaces, which can work as an artificial magnetic conductor. One method in fabrication of these surfaces is formation of a metamaterial by patterning a metallic surface in the shape of space filling curves (e.g. Hilbert or Peanu Curves). In this paper, we present a novel semi-analytical solution to the problem of plasmonic propagation on these surfaces. The method is based on a previously presented Green's function formalism, which has been reported in an earlier paper of ours. We have modified and improved the method for analysis of periodic structures with a large number of spatial harmonics, and used different methods to get the necessary stabilization. Here propagating modes of different structures and their corresponding frequencies are calculated, and the possibility of frequency gap formation and stability of the method are investigated.

    In this paper, we propose a new method to estimate the wave height of a specific return period based on the Hurst rule and a self-affine fractal formula. A detailed description of our proposed model is presented in this paper. We use the proposed model to analyze wave height data recorded along the coast of Chaolian Island from 1963 to 1989. The results show that the performance of our proposed model in estimating design wave heights is superior to traditional models.

    OBJECTIVE: To analyse the five-point tuberculosis (TB) strategy, DOTS, 10 years after its implementation in one-half of China's population, and to suggest lessons for future implementation of the DOTS strategy. METHODS: We analysed trends in case-finding and treatment outcome over time following implementation of the DOTS strategy in each county, using routine reporting data from the Infectious and Endemic Disease Control (IEDC) project (1991 - 2000). We also determined the proportion of counties with different levels of case-finding for the fifth and sixth years of DOTS implementation. FINDINGS: From 1991 to 1995, DOTS expanded rapidly to cover more than 90% of target population and counties. By 2000, 8 million TB suspects had received free diagnostic evaluation: 1.8 million TB cases were diagnosed, free treatment was provided to 1.3 million smear-positive cases, and more than 90% were cured. During DOTS implementation, the percentage of previously treated cases decreased among all smear-positive cases and treatment outcomes improved. Despite these achievements, the detection rate for new smear-positive cases in the project was estimated to be only 54% in 1998, and 41.2% of the counties had a below average or low level of case-finding (with substantial variation between provinces). CONCLUSIONS: The IEDC project demonstrated that it is feasible to rapidly expand DOTS on a large scale. The global target of an 85% cure rate was quickly achieved, and the level of drug-resistance was probably reduced by this project. However, case-detection did not reach the 70% global target, and more research is needed on how to enhance this. PMID:12131998

    Abstract Objective To determine whether the road safety policies introduced between 2000 and 2010 in Catalonia, Spain, which aimed primarily to reduce deaths from road traffic collisions by 50% by 2010, were associated with economic benefits to society. Methods A cost analysis was performed from a societal perspective with a 10-year time horizon. It considered the costs of: hospital admissions; ambulance transport; autopsies; specialized health care; police, firefighter and roadside assistance; adapting to disability; and productivity lost due to institutionalization, death or sick leave of the injured or their caregivers; as well as material and administrative costs. Data were obtained from a Catalan hospital registry, the Catalan Traffic Service information system, insurance companies and other sources. All costs were calculated in euros (€) at 2011 values. Findings A substantial reduction in deaths from road traffic collisions was observed between 2000 and 2010. Between 2001 and 2010, with the implementation of new road safety policies, there were 26 063 fewer road traffic collisions with victims than expected, 2909 fewer deaths (57%) and 25 444 fewer hospitalizations. The estimated total cost savings were around €18 000 million. Of these, around 97% resulted from reductions in lost productivity. Of the remaining cost savings, 63% were associated with specialized health care, 15% with adapting to disability and 8.1% with hospital care. Conclusion The road safety policies implemented in Catalonia in recent years were associated with a reduction in the number of deaths and injuries from traffic collisions and with substantial economic benefits to society.

    Background: Some studies have demonstrated the role of calcium in reducing body mass index (BMI) or fat mass. Though, BMI does not provide very valid information about changes in body fat mass, Fat Mass Index (FMI) relates body fat mass to height and allows comparing body fat mass of individuals at different heights. This study investigated the possible association between dietary calcium intake (CI) and other nutritional factors and weight status of girls aged 8-10 years. Materials and Methods: In this case-control study, 110 girls aged 8-10 with FMI at or above 7.2 kg/m2 as cases and 307 girls with FMI less than 7.2 kg/m2 as controls were recruited through multistage cluster random sampling. FMI at or above 7.2 kg/m2 was considered as the cutoff point for obesity. Body fat mass was assessed by a stand on bio impedance analyzer. In order to assess CI, participants were asked to complete a validated food frequency questionnaire. Results: Mean and standard deviation of CI in the case group was significantly lower than the control group 649 ± 103 and 951 ± 152 mg/d, respectively (P < 0.01). After Adjustment for total energy intake, the percentage of energy from fat, carbohydrate and protein in quartiles of physical activity, inverse association between CI and obesity was significant and in the highest quartile of physical activity the association was weaker. By further adjustment for the effect of fruits and vegetable intake inverse association between CI and obesity became weaker but yet was significant. Conclusion: The inverse relationship between CI and FMI remained significant even after controlling for confounding factors. FMI may be more accurate, compared to BMI, in showing the association between CI and obesity. PMID:23853625

    Background: Prenatal stress seems to have long-lasting effects on biological and psychological processes of the offspring. However, to date, there have been no studies investigating the effects of prenatal glucocorticoid exposure on psychological, endocrine, and autonomic responses to a standardized psychosocial stress test in children. Methods: A sample of 115 healthy, 10-year-old children was examined. The Glucocorticoids + Tocolytics group was characterized by tocolytic treatment of the mothers due to preterm labor (n = 43). In addition, the pregnant women received glucocorticoid treatment in order to accelerate fetal lung maturation in case of preterm birth. The first comparison group (Tocolytics) consisted of children whose mothers also experienced preterm labor, but did not receive glucocorticoid treatment (n = 35). In the second comparison group (CONTROL), children whose mothers had a complication-free pregnancy were assessed (n = 37). Psychological parameters (stress appraisal and mood) using self-report questionnaires as well as salivary cortisol, salivary alpha-amylase, and heart rate were measured during a standardized psychosocial stress test (Trier Social Stress Test for Children). Results: Group comparisons revealed that a subscale of stress appraisal, control expectancies, significantly differed in children who were prenatally exposed to glucocorticoids as compared to both comparison groups (F = 4.889, p = 0.009). Furthermore, significant differences between the groups were revealed for salivary cortisol. With respect to overall stress appraisal and heart rate, trends toward significance were observed between the three groups. Conclusion: At the age of ten, those children who have been exposed to prenatal maternal glucocorticoids show changed psychobiological stress reactivity to a standardized psychosocial stress test as compared to control children.

    Background: Healthcare-associated pneumonia (HCAP) is associated with drug-resistant pathogens and high mortality, and there is no clear evidence that this is due to inappropriate antibiotic therapy. This study was to elucidate the clinical features, pathogens, therapy, and outcomes of HCAP, and to clarify the risk factors for drug-resistant pathogens and prognosis. Methods: Retrospective observational study among hospitalized patients with HCAP over 10 years. The primary outcome was 30-day all-cause hospital mortality after admission. Demographics (age, gender, clinical features, and comorbidities), dates of admission, discharge and/or death, hospitalization costs, microbiological results, chest imaging studies, and CURB-65 were analyzed. Antibiotics, admission to Intensive Care Unit (ICU), mechanical ventilation, and pneumonia prognosis were recorded. Patients were dichotomized based on CURB-65 (low- vs. high-risk). Results: Among 612 patients (mean age of 70.7 years), 88.4% had at least one comorbidity. Commonly detected pathogens were Acinetobacter baumannii, Pseudomonas aeruginosa, and coagulase-negative staphylococci. Initial monotherapy with β-lactam antibiotics was the most common initial therapy (50%). Mean age, length of stay, hospitalization expenses, ICU admission, mechanical ventilation use, malignancies, and detection rate for P. aeruginosa, and Staphylococcus aureus were higher in the high-risk group compared with the low-risk group. CURB-65 ≥3, malignancies, and mechanical ventilation were associated with an increased mortality. Logistic regression analysis showed that cerebrovascular diseases and being bedridden were independent risk factors for HCAP. Conclusion: Initial treatment of HCAP with broad-spectrum antibiotics could be an appropriate approach. CURB-65 ≥3, malignancies, and mechanical ventilation may result in an increased mortality.

    PurposeCarotid endarterectomy and stenting are used to treat carotid stenosis, with the volume of carotid artery procedures increasing over the past decade. We investigated the 10-year trend of periprocedural complications with an increasing procedure volume of carotid stenting at a single tertiary hospital.MethodsWe collected 416 consecutive cases (384 patients) of carotid artery stenting performed for either symptomatic (231 cases, 55.5 %) or asymptomatic (185 cases, 44.5 %) internal carotid artery stenosis at a single center. Periprocedural complication was defined as any stroke, myocardial infarction, or death. Procedure-related outcome included any dissection, hemodynamic event, or periprocedural complication.ResultsThe mean age was 68.8 years (82.8 % males; range of 20–89 years); 23.9 % were older than 75 years. Before the procedure, 99.3 and 56.0 % of patients received antiplatelet and lipid-lowering medication, respectively. The overall periprocedural complication rate was 3.6 % (1.6 and 5.2 % in the asymptomatic and symptomatic group, respectively). The composite outcome of any stroke or death was 3.4 %. Periprocedural complication and procedure-related outcome showed a decremental trend with increasing procedure volume, and this trend remained after adjusting for confounders.ConclusionsOur study suggests that carotid stenting at an experienced center might reduce the periprocedural complications. Our periprocedural complication rate of carotid artery stenting may be comparable to, or somewhat lower than, that reported in other clinical trials.

    The prevalence of reported domestic violence or intimate partner violence has greatly increased, with approximately 1.5 million women violently assaulted annually in the United States by an intimate partner. Strangulation is often seen in violence against women, including domestic violence cases. Strangulation is defined as "a form of asphyxia characterized by closure of the blood vessels or air passages of the neck as a result of external pressure on the neck." This is a 10-year case review of 102 living victims of strangulation who underwent medicolegal evaluation at the Clinical Forensic Medicine Program at a State Medical Examiner's Office serving Southern Indiana and all of Kentucky. The majority of victims (79%) were strangled by an intimate partner, and manual strangulation was the most common method (83%). A total of 38 victims (38%) described a history of domestic violence, and the same number lost consciousness while being strangled. Nine (9%) women were pregnant at the time of the attack, while 13 (13%) had a history of being sexually abused in addition to being strangled. A paucity of cases involved only strangulation, as most of the victims were subjected to myriad forms of blunt force trauma which included not only the head and neck but also other bodily regions. This is a unique presentation of strangulation of living persons as most evidence of strangulation in the forensic literature has been derived from postmortem examinations of the victims. This comprehensive study discussing the examination of a living strangulation victim offers valuable insight into the mechanism and the physical findings involved in the strangulation process.

    Introduction Acquired immunodeficiency syndrome is one of the most serious public health and development challenges in sub-Saharan Africa, including Ethiopia. A particular challenge for prevention strategies has been the emergence of hotspot areas. Therefore, human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome programs should not be based on national level statistics, but need to be more focused geographically. Kombolcha is one of the high spot areas with different projects and development corridors. Hence, the aim of this study is to assess the trend of HIV infection rates among patients who visited Africa Service Committee clinic from 2005 to 2014. Methods An institutional-based cross-sectional study was conducted from January 1 to January 30, 2016. All records of new patients enrolled from February 8, 2005 to December 31, 2014 were reviewed. Data on sociodemographic information, risky sexual behavior, and HIV test result were collected from each study participant using data collection format. Data were analyzed using SPSS version 20.0. A multivariate logistic regression model was used to identify risk factors of HIV infection. Results The overall HIV infection was 10.8% (2,233/20,674). The rate of infection varied from 13.3% in 2005 to 4.5% in 2014, and its trend had significantly declined from 2008 to 2014. Urban residence (adjusted odds ratio [AOR]: 2.53; 95% confidence interval [CI]: 1.22–5.25), patients who ever had intercourse with penetration (AOR: 5.62; 95% CI: 1.11–28.57), and those who had marriage experience (AOR: 11.65; 95% CI: 4.2–32.3) were more infected with HIV. Conclusion The trend of HIV infection significantly reduced in the last 10 years in Kombolcha area. However, the HIV infection still remains high (4.5%) that needs intervention of those who had marriage experience, risky sexual behavior, and urban dwellers. PMID:27462177

    The influence of harvest period and harvest method on olive oil composition was investigated by nuclear magnetic resonance (NMR) spectroscopy and by some quality parameters such as free acidity, peroxide value, and UV spectrophotometric indices. This work focuses on two secondary factors (harvest period and harvest method) and investigated their interactions with primary (genetic and pedoclimatic) and secondary (agronomic practices and technological procedures) factors. To avoid misinterpretation, the general linear model analysis (GLM) was used to adjust the result obtained from the analysis of variance (ANOVA). In this way, the effect of the factor of interest was corrected for the effects of the other factors that might influence the variable under investigation. The weight of each factor was evaluated by the variance component analysis (VCA). Finally, multivariate statistical analyses, namely, principal component analysis (PCA) and linear discriminant analysis (LDA), were applied. Samples were grouped according to the harvest period and harvest method. Volatile compounds, that is, hexanal and trans-2-hexenal, as well as the sn-1,3-diglycerides and squalene, significantly decreased during the ripening. The relative value of the ΔK parameter and the hexanal amount were higher in the olive oils obtained from olives harvested by one type of hand-held machine (shaker), whereas the unsaturated fatty chains in the olive oils were higher when another type (comb) was used.

    Patients' selection criteria, effectiveness, and safety of radiofrequency thermal ablation (RFTA) therapy for uterine myomas (UM) were assessed using a 10-year retrospective cohort study. From July 2001 to July 2011, a total of 1216 patients treated for UM were divided into 2 groups. Group A consisted of 476 premenopause patients, average age 36.5 ± 8.5 years, average number of myomas 1.7 ± 0.9, and average diameter of myomas 4.5 ± 1.5 cm, and group B consisted of 740 menopause patients, average age 48.5 ± 3.5 years, average number of myomas 2.6 ± 1.3, and average diameter of myomas 5.0 ± 2.5 cm. Average follow-up period was 36.5 ± 11.5 months. At 1, 3, 6, 12, and 24 months after RFTA, average diameters of myomas in group A were 3.8, 3.0, 2.7, 2.4, and 2.2 cm, respectively, and 47.7% (227 of 476) of patients had tumor trace at 12 months after RFTA. In group B, the results were 4.7, 3.7, 3.3, 2.3, and 2.3 cm, respectively, and 58.8% (435 of 740) of patients had tumor trace at 12 months after RFTA. Three months after treatment, myoma volumes were significantly reduced in both the groups (P < .01), and group B had higher rate of tumor trace at 12 months after RFTA than group A (P < .05). Clinical symptoms and health-related quality-of-life outcome (HRQL) were significantly improved after RFTA in both groups and the postoperative recurrence rate of UM was significantly higher in group A at 10.7% (51 of 476) than group B at 2.4% (18 of 740; P < .05). Radiofrequency thermal ablation is an excellent minimally invasive treatment for UM smaller than 5.0 cm in diameter.

    Adipose tissue tumors in ten years of diagnostic activity (1979-1988). We have reconsidered our material on tumors of adipose tissue, which were observed for 10 years, from 1979 to 1988, at Istituto di Anatomia Patologica dell'Università degli Studi - Arcispedale S. Anna di Ferrara. The whole collection consists of 772 tumors, 742 lipomas and 30 liposarcomas. We have intended to examine the development of our diagnostic experience through time and compare our data with those of literature. Simple lipomas and fibrolipomas are the most common histological types (78.8%), followed by angiolipomas (3.6%) and intramuscular lipomas (2.5%). The other types have a lower percentage. In every cases the morphologic and clinicopathologic features are shown, as well as compared with those of literature, and discordances that may result are interpreted. We are firmly convinced that routine diagnosis is not always compatible with rigid classifications and that it is not easy to use morphologic criteria which vary in quality and quantity. We have consequently aimed at reducing any possible distortion in diagnosis due to subjectivity, by sticking rigorously to consolidated morphology. Although our findings mostly agree with those of literature, some discordances still exist; the most significant of them regard age incidence. Among spindle cell lipomas there are two cases diagnosed in early childhood; the number of angiolipomas as well seems to be very high in this period of life. Particularly important from the clinical point of view has been the decision of diagnosing a thigh tumor as lipoblastoma in an eighteen-year-old boy. Other discordances seem to us less significant, as, for example, the absence of intramuscular lipomas in the thigh, which is to be considered, in our opinion, a chance event that we could not explain otherwise. Liposarcomas represent the 4% of the cases. Only one cases has been diagnosed in a patient less than 40 years old. The location sites agree with those

  13. Evaluation of selected methods for determining streamflow during periods of ice effect

    1992-01-01

    Seventeen methods for estimating ice-affected streamflow are evaluated for potential use with the U.S. Geological Survey streamflow-gaging station network. The methods evaluated were identified by written responses from U.S. Geological Survey field offices and by a comprehensive literature search. The methods selected and techniques used for applying the methods are described in this report. The methods are evaluated by comparing estimated results with data collected at three streamflow-gaging stations in Iowa during the winter of 1987-88. Discharge measurements were obtained at 1- to 5-day intervals during the ice-affected periods at the three stations to define an accurate baseline record. Discharge records were compiled for each method based on data available, assuming a 6-week field schedule. The methods are classified into two general categories-subjective and analytical--depending on whether individual judgment is necessary for method application. On the basis of results of the evaluation for the three Iowa stations, two of the subjective methods (discharge ratio and hydrographic-and-climatic comparison) were more accurate than the other subjective methods and approximately as accurate as the best analytical method. Three of the analytical methods (index velocity, adjusted rating curve, and uniform flow) could potentially be used at streamflow-gaging stations, where the need for accurate ice-affected discharge estimates justifies the expense of collecting additional field data. One analytical method (ice-adjustment factor) may be appropriate for use at stations with extremely stable stage-discharge ratings and measuring sections. Further research is needed to refine the analytical methods. The discharge-ratio and multiple-regression methods produce estimates of streamflow for varying ice conditions using information obtained from the existing U.S. Geological Survey streamflow-gaging network.

  14. Periodic Pulay method for robust and efficient convergence acceleration of self-consistent field iterations

    2016-01-21

    Pulay's Direct Inversion in the Iterative Subspace (DIIS) method is one of the most widely used mixing schemes for accelerating the self-consistent solution of electronic structure problems. In this work, we propose a simple generalization of DIIS in which Pulay extrapolation is performed at periodic intervals rather than on every self-consistent field iteration, and linear mixing is performed on all other iterations. Lastly, we demonstrate through numerical tests on a wide variety of materials systems in the framework of density functional theory that the proposed generalization of Pulay's method significantly improves its robustness and efficiency.

    The aim of this prospective and blind clinical trial was to assess the effectiveness of sealing localized marginal defects of amalgam restoration that were initially scheduled to be replaced. A cohort of twenty six patients with 60 amalgam restorations (n=44Class I and n=16Class II), that presented marginal defects deviating from ideal (Bravo) according to USPHS criteria, were assigned to either sealing or replacement groups: A: sealing n=20, Replacement n=20, and no treatment (n=20). Two blind examiners evaluated the restorations at baseline (K=0.74) and after ten years (K=0.84) according with USPHS criteria, in four parameters: marginal adaptation (MA), secondary caries (SC), marginal staining (MS) and teeth sensitivity (TS). Multiple comparison of restorations degradation/upgrade was analyzed by Friedman test and the comparisons within groups were performed by Wilcoxon test. After 10 years, 44 restorations were assessed (73.3%), Group A: n=14 and Group B: n=16; and Group C: n=14 sealing and replacement amalgam restorations presented similar level of quality in MA (p=0.76), SC (p=0.25) and TS (p=0.52), while in MS (p=0.007) presented better performance in replacement group after 10-years. Most of the occlusal amalgam restorations with marginal gaps showed similar long term outcomes than the restorations were sealed, replaced, or not treated over a 10-year period. Most of the restorations of the three groups were clinically acceptable, under the studied parameters. All restorations had the tendency to present downgrade/deterioration over time.

  16. Analysis of periodic anisotropic media by means of split-field FDTD method and GPU computing

    The implementation of the Split-Field Finite Difference Time-Domain (SP-FDTD) method in Graphics Pro- cessing Units is described in this work. This formalism is applied to light wave propagation through periodic media with arbitrary anisotropy. The anisotropic media is modeled by means of a permittivity tensor with non-diagonal elements and absorbing boundary conditions are also considered. The split-field technique and the periodic boundary condition allow to consider a single period of the structure reducing the simulation grid. Nevertheless, the analysis of anisotropic media implies considering all the electromagnetic field components and the use of complex notation. These aspects reduce the computational efficiency of the numerical method compared to the isotropic and non-periodic implementation. With the upcoming of the new generation of General-Purpose Computing on Graphics Units many scientific applications have been accelerated and others are being developed into this new parallel digital computing architecture. Specifically, the implementation of the SP-FDTD in the Fermi family of GPUs of NVIDIA is presented. An analysis of the performance of this implementation is done and several applications have been considered in order to estimate the possibilities provided by both the formalism and the implementation into GPU. The formalism has been used for analyzing different structures and phenomena: binary phase gratings and twisted-nematic liquid crystal cells. The numerical predictions obtained by means of the FDTD method here implemented are compared with theoretical curves achieving good results, thus validating the accuracy and the potential of the implementation.

    Chronic kidney disease (CKD) patients not yet in dialysis can benefit from increased physical activity; however, the safety and outcomes of aquatic exercise have not been investigated in observational studies. The aim of this study was to analyze association of 10 years of regularly performed aquatic exercise with the study endpoint--that is, all-cause death or start of dialysis. Consecutive CKD patients were included in the study in January 2002. The exercise group (n=7) exercised regularly under the supervision of physiotherapist for 10 years; the control group (n=9), matched in terms of age and clinical parameters, remained sedentary. Low-intensity aerobic aquatic exercise was performed regularly twice a week; 32 weeks or more of exercise therapy sessions were conducted annually. None of the members of the aquatic exercise group reached dialysis or died in 10 years. In the sedentary control group, 55% reached the study endpoint--renal replacement therapy (n=2) or all-cause death (n=3). Occurrence of the study endpoint, compared using the exact multinomial test with unconditional margins, was statistically significantly different (P-value: 0.037) between the study groups. Regular supervised aquatic exercise arrested CKD progression. There was a statistically significant difference between the sedentary group and the exercise group in reaching renal replacement therapy or all-cause death in a follow-up time of 10 years.

    Background The comparative effectiveness of treatments for prostate cancer that is detected by prostate-specific antigen (PSA) testing remains uncertain. Methods We compared active monitoring, radical prostatectomy, and external-beam radiotherapy for the treatment of clinically localized prostate cancer. Between 1999 and 2009, a total of 82,429 men 50 to 69 years of age received a PSA test; 2664 received a diagnosis of localized prostate cancer, and 1643 agreed to undergo randomization to active monitoring (545 men), surgery (553), or radiotherapy (545). The primary outcome was prostate-cancer mortality at a median of 10 years of follow-up. Secondary outcomes included the rates of disease progression, metastases, and all-cause deaths. Results There were 17 prostate-cancer-specific deaths overall: 8 in the active-monitoring group (1.5 deaths per 1000 person-years; 95% confidence interval [CI], 0.7 to 3.0), 5 in the surgery group (0.9 per 1000 person-years; 95% CI, 0.4 to 2.2), and 4 in the radiotherapy group (0.7 per 1000 person-years; 95% CI, 0.3 to 2.0); the difference among the groups was not significant (P=0.48 for the overall comparison). In addition, no significant difference was seen among the groups in the number of deaths from any cause (169 deaths overall; P=0.87 for the comparison among the three groups). Metastases developed in more men in the active-monitoring group (33 men; 6.3 events per 1000 person-years; 95% CI, 4.5 to 8.8) than in the surgery group (13 men; 2.4 per 1000 person-years; 95% CI, 1.4 to 4.2) or the radiotherapy group (16 men; 3.0 per 1000 person-years; 95% CI, 1.9 to 4.9) (P=0.004 for the overall comparison). Higher rates of disease progression were seen in the active-monitoring group (112 men; 22.9 events per 1000 person-years; 95% CI, 19.0 to 27.5) than in the surgery group (46 men; 8.9 events per 1000 person-years; 95% CI, 6.7 to 11.9) or the radiotherapy group (46 men; 9.0 events per 1000 person-years; 95% CI, 6.7 to 12.0) (P<0

  17. Acoustic scattering for 3D multi-directional periodic structures using the boundary element method.

    2017-01-01

    An efficient boundary element formulation is proposed to solve three-dimensional exterior acoustic scattering problems with multi-directional periodicity. The multi-directional periodic acoustic problem is represented as a multilevel block Toeplitz matrix. By exploiting the Toeplitz structure, the computational time and storage requirements to construct and to solve the linear system of equations arising from the boundary element formulation are significantly reduced. The generalized minimal residual method is implemented to solve the linear system of equations. To efficiently calculate the matrix-vector product in the iterative algorithm, the original matrix is embedded into a multilevel block circulant matrix. A multi-dimensional discrete Fourier transform is then employed to accelerate the matrix-vector product. The proposed approach is applicable to a periodic acoustic problem for any arbitrary shape of the structure in both full space and half space. Two case studies involving sonic crystal barriers are presented. In the first case study, a sonic crystal barrier comprising rigid cylindrical scatterers is modeled. To demonstrate the effectiveness of the proposed technique, periodicity in one, two, or three directions is examined. In the second case study, the acoustic performance of a sonic crystal barrier with locally resonant C-shaped scatterers is studied.

    We propose the nonlinear Fourier Modal Method (FMM) [J. Opt. Soc. Am. B 31, 2371 (2014)] as a convenient and versatile numerical tool for the design and analysis of grating based next generation all-optical devices. Here, we include several numerical examples where the FMM is used to simulate all-optically tunable functionalities in sub-wavelength periodic structures. At first, we numerically investigate a 1-D periodic nonlinear binary grating with amorphous TiO2. We plot the diffraction efficiency in the transmitted orders against the structure depth for normally incident plane wave. Change in diffraction efficiencies for different incident field amplitudes are evident from the plots. We verify the accuracy of our implementation by comparing our results with the results obtained with the nonlinear Split Field-Finite Difference Time Domain (SF-FDTD) method. Next we repeat the same experiment with vertically standing amorphous Titanium dioxide (TiO2) nanowire arrays grown on top of quartz which are periodic in two mutually perpendicular directions and examine the efficiencies in the direct transmitted light for different incident field amplitudes. Our third example includes analysis of a form birefringent linear grating with Kerr medium. With FMM we demonstrate that the birefringence of such a structure can be tuned by all-optical means. As a final example, we design a narrow band Guided Mode Resonance Filter (GMRF). Numerical experiments based on the nonlinear FMM reveal that the spectral tunability of such a filter can be obtained by all-optical means.

    This study investigates the 10-year course and impact of AA-related helping (AAH), step-work, and meeting attendance on long-term outcomes. Data were derived from 226 treatment-seeking alcoholics recruited from an outpatient site in Project MATCH and followed for 10 years post-treatment. Alcohol consumption, AA participation, and other-oriented behavior were assessed at baseline, end of the 3-month treatment period, and one year, three years, and 10 years post-treatment. Controlling for explanatory baseline and time-varying variables, results showed significant direct effects of AAH and meeting attendance on reduced alcohol outcomes and a direct effect of AAH on improved other-oriented interest.

    In this work, we introduce the periodic nonlinear Fourier transform (PNFT) method as an alternative and efficacious tool for compensation of the nonlinear transmission effects in optical fiber links. In the Part I, we introduce the algorithmic platform of the technique, describing in details the direct and inverse PNFT operations, also known as the inverse scattering transform for periodic (in time variable) nonlinear Schrödinger equation (NLSE). We pay a special attention to explaining the potential advantages of the PNFT-based processing over the previously studied nonlinear Fourier transform (NFT) based methods. Further, we elucidate the issue of the numerical PNFT computation: we compare the performance of four known numerical methods applicable for the calculation of nonlinear spectral data (the direct PNFT), in particular, taking the main spectrum (utilized further in Part II for the modulation and transmission) associated with some simple example waveforms as the quality indicator for each method. We show that the Ablowitz-Ladik discretization approach for the direct PNFT provides the best performance in terms of the accuracy and computational time consumption.

    A method for fabricating a periodic dielectric structure which exhibits a photonic band gap. Alignment holes are formed in a wafer of dielectric material having a given crystal orientation. A planar layer of elongate rods is then formed in a section of the wafer. The formation of the rods includes the step of selectively removing the dielectric material of the wafer between the rods. The formation of alignment holes and layers of elongate rods and wafers is then repeated to form a plurality of patterned wafers. A stack of patterned wafers is then formed by rotating each successive wafer with respect to the next-previous wafer, and then placing the successive wafer on the stack. This stacking results in a stack of patterned wafers having a four-layer periodicity exhibiting a photonic band gap.

    The orderly build-up of monosized microspheres with sizes of hundreds of micrometres enabled us to develop three-dimensional (3D) photonic crystal devices for terahertz electromagnetic waves. We designed and manufactured an original 3D particle assembly system capable of fabricating arbitrary periodic structures from these spherical particles. This method employs a pick-and-place assembling approach with robotic manipulation and interparticle laser microwelding in order to incorporate a contrivance for highly accurate arraying: an operation that compensates the size deviation of raw monosized particles. Pre-examination of particles of various materials revealed that interparticle laser welding must be achieved with local melting by suppressing heat diffusion from the welding area. By optimizing the assembly conditions, we succeeded in fabricating an accurate periodic structure with a diamond lattice from 400 µm polyethylene composite particles. This structure demonstrated a photonic bandgap in the terahertz frequency range.

    The aim of this study was to assess the reproducibility and validity of a non-quantitative 28-item food frequency questionnaire (FFQ). Children aged 9–10 years (n = 50) from three schools in Dunedin, New Zealand, completed the FFQ twice and a four-day estimated food diary (4DEFD) over a two-week period. Intraclass correlation coefficients (ICC) and Spearman’s correlation coefficients (SCC) were used to determine reproducibility and validity of the FFQ, respectively. Weekly intakes were estimated for each food item and aggregated into 23 food items/groups. More than half of the food items/groups (52.2%) had an ICC ≥0.5. The median SCC between FFQ administrations was 0.66 (ranging from 0.40 for processed meat to 0.82 for sweets and non-dairy drinks). Cross-classification analysis between the first FFQ and 4DEFD for ranking participants into thirds showed that breakfast cereals had the highest agreement (54.0%) and pasta the lowest (34.0%). In validity analyses, 70% of food items/groups had a SCC ≥0.3. Results indicate that the FFQ is a useful tool for ranking children according to food items/groups intake. The low respondent burden and relative simplicity of the FFQ makes it suitable for use in large cohort studies of 9–10 year-old children in New Zealand. PMID:27164137

    Tree population dynamics in subalpine forests of the Canadian Rockies are dominated by wildfire disturbance (Gallaway et al., 2009), with wildfire return intervals most often being shorter than the potential lifespan of trees. These crown wildfires kill all trees, resulting in a gradual decline of tree root strength in shallow soils in the immediate post-wildfire years. Tree root networks have been shown to provide mechanical reinforcement of shear strength in shallow soils (Schmidt et al., 2001; Roering et al., 2003). Therefore, decreases in tree root reinforcement in post-wildfire years may result in increased debris slide and debris flow activity during this time period (e.g., Benda and Dunne, 1997; Martin, 2007; Jackson and Roering, 2009). To our knowledge, our study is the first that has measured tree root strength annually for 10 years following a crown wildfire to document the nature and timing of tree root decay. Suggestions have been made that studies documenting the decay of tree roots following timber harvesting provide a reasonable analogue for post-wildfire tree root decay; drainage basin modeling studies considering hillslope erosion resulting from episodic wildfires have had to rely on this assumption (e.g., Benda and Dunne, 1997; Martin, 2007). Herein, we present our annual field measurements of post-wildfire tree root strength made over the past 10 years at a post-wildfire site in Kootenay National Park, Canadian Rockies. The episodic nature of crown wildfire occurrence over time in these forests results in periods of tree root decay in the immediate post-fire years, and an associated susceptibility for mass wasting during these time periods. In July 2003, two large crown fires were ignited by lightning in Kootenay National Park, British Columbia, Canada and merged to burn approximately 17 000 hectares. Our field measurements were made in the subalpine forest of Hawk Creek drainage basin, Kootenay National Park. Measurements of tree root

    Although being a relatively old phenomenon, drug-facilitated crime has been well described over the past 20 years as being the administration without the knowledge of the victim of a psychoactive substance in criminal purposes (rape, robbery, theft, money extortion, even murder). Drug-facilitated crime involves also mistreatment of older people or children treated by their parents in order to obtain sedation. Drug-facilitated crimes are often difficult to solve mainly due to analytical issues. Since 10 years, we developed and improved specific methods using LC-MS/MS (benzodiazepines, neuroleptics) and GC-MS/MS (GHB, cannabis) to detect the drugs involved in such crimes. After the intake of a low dosage of a particular drug, those methods allow to detect the analyte of interest up to 3-5 days in blood, 10-15 days in urine, and more than 1 year in hair. In drug-facilitated crime cases, blood and urine are frequently collected too late, more than 12 h after the drug intake and in some cases with a delay greater than 48 h after the event. Thus, the most used molecules are undetectable by the techniques classically used in a laboratory of biology. Moreover, a "good" compound that can be used to commit a drug-facilitated crime usually possesses a short elimination half-life and amnesic properties, so that the victim is less able to accurately recall the circumstances under which the offence occurred. The recent progress in analytical toxicology, particularly for laboratories working in the field of forensic toxicology, permits to elucidate many cases of drug-facilitated crimes. Heaven to the introduction of the sequential analysis of hair and the use of sophisticated analytical techniques such as tandem mass-spectrometry for the toxicologist to bring the scientific proof to the applicant authorities in the description of the criminal act and to confuse the offender.

    Direct numerical simulation (DNS) of turbulent compressible flows is performed using a higher-order space-time discontinuous-Galerkin finite-element method. The numerical scheme is validated by performing DNS of the evolution of the Taylor-Green vortex and turbulent flow in a channel. The higher-order method is shown to provide increased accuracy relative to low-order methods at a given number of degrees of freedom. The turbulent flow over a periodic array of hills in a channel is simulated at Reynolds number 10,595 using an 8th-order scheme in space and a 4th-order scheme in time. These results are validated against previous large eddy simulation (LES) results. A preliminary analysis provides insight into how these detailed simulations can be used to improve Reynoldsaveraged Navier-Stokes (RANS) modeling

    Parabolic equation (PE) method is an efficient tool for modelling underwater sound propagation, particularly for problems involving range dependence. Since the PE method was first introduced into the field of underwater acoustics, it has been about 40 years, during which contributions to extending its capability has been continuously made. The most recent review paper surveyed the contributions made before 1999. In the period of 2000-2016, the development of PE method basically focuses on seismo-acoustic problems, three-dimensional problems, and realistic applications. In this paper, a review covering the contribution from 2000 to 2016 is given, and what should be done in future work is also discussed.

    2007-07-01

    Methods for micro- and nanostructuring are essential for functionalization of materials surfaces. In particular, photon-assisted methods for synthesis of functional surfaces have been intensively investigated in the last years. In this study, a new method for surface modification and production of long-range order periodical structures called "laser interference metallurgy" is explored. A metallic thin film sample consisting of three layers composed of Fe, Cu and Al (from top to bottom) on a glass substrate was irradiated with an interference pattern using a Nd:YAG laser (wavelength of 355 nm, 10 ns of pulse duration). For the interference pattern, a configuration producing a line-type energy distribution was chosen. The laser fluence was high enough to melt the aluminium and copper layers at the interference maxima but the iron layer remained in the solid state. Thus, diffusive and convective exchange occurred between aluminium and copper at the energy maxima positions leading to periodical alloy formation with a long-range order. Because it remained in solid state, the iron layer at the top acted as a protective layer effectively preventing removal of the molten layers. The interaction of the different layers was characterized using FIB, TEM and EDX in STEM mode.

    In this work we discuss a method to generate laterally periodic polycrystalline samples with fractal surfaces for use in molecular dynamics simulations of abrasion. We also describe a workflow that allows us to produce random lateral distributions of simple but realistically shaped hard abrasive particles with Gaussian size distribution and random particle orientations. We evaluate some on-the-fly analysis and visualization possibilities that may be applied during a molecular dynamics simulation to considerably reduce the post-processing effort. Finally, we elaborate on a parallelizable post-processing approach to evaluating and visualizing the surface topography, the grain structure and orientation, as well as the temperature distribution in large atomistic systems.

    Zhou, Hengyan; Zeng, Lijiang

    2017-02-01

    We present a method to make optical mosaic orthogonally crossed gratings by utilizing information about both main periodic directions simultaneously. The whole mosaic system for orthogonally crossed gratings is set up based on the dual Lloyd's mirror interferometer that fabricates orthogonally crossed gratings through a single exposure. The interference fringes formed by the diffractions of the exposure beams from the exposed grating areas are used as the reference to fine tune the position and attitude of the exposure beams relative to the substrates during consecutive exposures. A procedure to make mosaic for two main periodic directions simultaneously is proposed based on the presupposition that the angle between two sets of main lattice lines is constant during the mosaic. Experimentally we made a 2×1 mosaic crossed grating with a period of 574 nm in (30+30) mm ×35 mm area. The peak-valley errors of the (-1, 0)th- and (0, -1)st-order diffraction wavefronts over the whole mosaic grating area are 0.104λ and 0.163λ, respectively.

    Faced with a scientific and legal debate on human embryo cryopreservation in Poland we show 5 documented clinical cases of successful thawing and transfer of embryos cryopreserved for a long period of time (8-11 years), resulting in successful delivery by the biological or the recipient mother. Cases described include patients with different infertility diagnoses, subjected to different hormonal stimulation treatments. Different oocyte fertilization methods were performed, and the obtained embryos were frozen after 2, 3 or 4 days of in vitro culture using methods employing various cryoprotective agents and freezing curves. As a result of performed thawing and transfer procedures normal, healthy babies were born. Our results are consistent with the international reports on successful long-term storage of embryos, (including the longest known period of over 19 years) resulting in no detectable reduction of the developmental potential after thawing. In light of data shown here, we do not see any medical or biological reasons for legally-regulated limitation of the period of frozen embryo storage. Moreover, if frozen, long-term stored embryos are not threatened by destruction and if prenatal adoption is a real, clinically documented option, we fail to see any reason for legal limitations of embryo cryopreservation in human infertility treatment.

    The paper presents different periodical capacity setting methods for make-to-order, multi-machine production systems with stochastic customer required lead times and stochastic processing times to improve service level and tardiness. These methods are developed as decision support when capacity flexibility exists, such as, a certain range of possible working hours a week for example. The methods differ in the amount of information used whereby all are based on the cumulated capacity demand at each machine. In a simulation study the methods' impact on service level and tardiness is compared to a constant provided capacity for a single and a multi-machine setting. It is shown that the tested capacity setting methods can lead to an increase in service level and a decrease in average tardiness in comparison to a constant provided capacity. The methods using information on processing time and customer required lead time distribution perform best. The results found in this paper can help practitioners to make efficient use of their flexible capacity.

    DISCOVER (Distributed Information Services: Climate/Ocean Products and Visualization for Earth Research) is a NASA MEaSUREs funded project that delivers ocean surface wind, water vapor, cloud, sea surface temperature and rain products to the scientific community. We have delivered these data to users via the Internet for over 10 years thanks to successive funding (Pathfinder, ESIP, REASoN and now MEaSUREs). Since we are a group of scientists who use the data ourselves in research, our approach to providing DISCOVER data to the user community is based on what we would want; that is, we provide simple file formats that are quick to download and easy to transfer between computer systems, with read routines and files to check whether the data are correct after transfer, and helpful, quick and accurate user support. Web and FTP user metrics collected since 1998 show a continual increase in activity and file downloads. Most importantly, the DISCOVER data are now essential building blocks to other value-added products created by scientists for the research community, such as the CCMP winds (another NASA MEaSUREs funded project). An extensive list of publications presenting results obtained through use of the DISCOVER data demonstrates the demand for and long-term use of the DISCOVER ocean data products by scientists. Our products are generated after extensive intercalibration, algorithm refinement, quality control checks, geolocation and satellite attitude adjustments, along-scan bias corrections, hot load or antenna emissivity corrections, sun glitter and RFI removal and independent validation. In this talk, we will summarize our methods and tools used in producing the various DISCOVER data products, describe the means by which we distribute the data to users and support them in their research, list the types of value-added products available, and present some of the ways in which the data are being used to answer important scientific and climate questions.

    Background and Aims The increase in overweight and obese children may be linked to increased rates of dyslipidaemia. The aim was to assess the prevalence of dyslipidaemia and associated risk factors among the Northern Mexican child population. Methods and Results Four hundred and fifty-one subjects aged between 2 and 10 (47.5% girls) took part in the Nuevo León State Survey of Nutrition and Health 2011–2012. According to the 2011 Expert Panel on Integrated Guidelines for Cardiovascular Health and Risk Reduction in Children and Adolescents, serum lipid levels (mg/dL) were categorized into three subgroups (acceptable, borderline-high/low or high/low) as follows: TChol: acceptable <170, borderline-high 170–199, high ≥200; LDL-chol: acceptable <110, borderline-high 110–129, high ≥130; non-HDL-chol: acceptable <120, borderline-high 120–144, high ≥145; HDL-chol: acceptable >45, borderline-low 40–45, low <40; and TG: acceptable <75, borderline-high 75–99, high ≥100 in ≤9 year-old children, and acceptable <90, borderline-high 90–129, and high ≥130 in 10 year-old children. The overall prevalence of borderline-high + high TG, non-HDL-chol, TChol, and LDL-chol was 63.0%, 44.1%, 43.5%, and 29.9%, respectively. The overall prevalence of borderline-low + low HDL-chol was 46.3%. The overall frequency of dyslipidaemia was 54.3%. Thirteen children (2.9%) had all five symptoms of dyslipidaemia. The most common dyslipidaemia was high TG in combination (26.2%) and in isolation (10.6%). Conclusions Half of the children had at least one abnormal lipid concentration. A high TG level was the most frequent dyslipidaemia. Obesity was associated with the occurrence of at least one abnormal lipid level. These findings emphasize the need to pay further attention to the prevention of cardiovascular disease and obesity from an early age. PMID:25793380

  19. Trends in aqueous hydration across the 4f period assessed by reliable computational methods.

    The geometric and electronic structures, as well as the thermodynamic properties of trivalent lanthanide hydrates {Ln(H(2)O)(8,9)(3+) and Ln(H(2)O)(8,9)(H(2)O)(12,14)(3+), Ln = La-Lu} have been examined using unrestricted density functional theory (UDFT), unrestricted Möller-Plesset perturbation theory (UMP2), and multiconfigurational self-consistent field methods (MCSCF). While Ln-hydrates with 2-5 unpaired f-electrons have some multiconfigurational character, the correlation energy lies within 5-7 kcal/mol across the period and for varying coordination numbers. As such DFT yields structural parameters and thermodynamic data quite close to experimental values. Both UDFT and UMP2 predict free energies of water addition to the Ln(H(2)O)(8)(3+) species to become less favorable across the period; however, it is a non-linear function of the surface charge density of the ion. UDFT further predicts that the symmetry of the metal-water bond lengths is sensitive to the specific f-electron configuration, presumably because of repulsive interactions between filled f-orbitals and water lone-pairs. Within the Ln(H(2)O)(8,9)(H(2)O)(12,14)(3+) clusters, interactions between solvation shells overrides this orbital effect, increasing the accuracy of the geometric parameters and calculated vibrational frequencies. Calculated atomic charges indicate that the water ligands each donate 0.1 to 0.2 electrons to the Ln(III) metals, with increasing electron donation across the period. Significant polarization and charge transfer between solvation shells is also observed. The relationship between empirical effective charges and calculated atomic charges is discussed with suggestions for reconciling the trends across the period.

    In the present study, we jointly employ and integrate variable- and person-centered approaches to identify groups of individuals with autism spectrum disorders (ASD) who have similar profiles of change over a period of 10 years across three critical domains of functioning: maladaptive behaviors, autism symptoms, and daily living skills. Two distinct developmental profiles were identified. Above and beyond demographic and individual characteristics, aspects of both the educational context (level of inclusion) and the family context (maternal positivity) were found to predict the likelihood of following a positive pattern of change. Implementing evidence-based interventions that target the school and home environments during childhood and adolescence may have lasting impacts on functioning into adulthood for individuals with ASD.

    2010-11-01

    Healthy food baskets have been used around the world for a variety of purposes, including: examining the difference in cost between healthy and unhealthy food; mapping the availability of healthy foods in different locations; calculating the minimum cost of an adequate diet for social policy planning; developing educational material on low cost eating and examining trends on food costs over time. In Australia, the Illawarra Healthy Food Basket was developed in 2000 to monitor trends in the affordability of healthy food compared to average weekly wages and social welfare benefits for the unemployed. It consists of 57 items selected to meet the nutritional requirements of a reference family of five. Bi-annual costing from 2000-2009 has shown that the basket costs have increased by 38.4% in the 10-year period, but that affordability has remained relatively constant at around 30% of average household incomes.

    In 2002, the first Chinese domestic preservative-free inactivated hepatitis A vaccine, Healive®, was introduced in China. It is highly immunogenic, and provides lasting protection in healthy individuals and generates protective levels of antibodies in other at-risk individuals. Over 10 years since its first licensure, postmarketing surveillance data have confirmed the outstanding safety profile of the vaccine. Comparative clinical trials indicated that Healive® induce equal or similar immunogenicity with other currently available inactivated hepatitis A vaccines and are interchangeable for the course of HAV immunization in Chinese children. The vaccine is effective in curbing outbreaks of hepatitis A due to rapid seroconversion and the long incubation period of the disease. Additional issues surrounding the use of the vaccine are also reviewed. PMID:23032165

    The 7-day, 10-year (7Q10) low-flow-frequency statistic is a widely used measure of surface-water availability in New Hampshire. Regression equations and basin-characteristic digital data sets were developed to help water-resource managers determine surface-water resources during periods of low flow in New Hampshire streams. These regression equations and data sets were developed to estimate streamflow statistics for the annual and seasonal low-flow-frequency, and period-of-record and seasonal period-of-record flow durations. generalized-least-squares (GLS) regression methods were used to develop the annual 7Q10 low-flow-frequency regression equation from 60 continuous-record stream-gaging stations in New Hampshire and in neighboring States. In the regression equation, the dependent variables were the annual 7Q10 flows at the 60 stream-gaging stations. The independent (or predictor) variables were objectively selected characteristics of the drainage basins that contribute flow to those stations. In contrast to ordinary-least-squares (OLS) regression analysis, GLS-developed estimating equations account for differences in length of record and spatial correlations among the flow-frequency statistics at the various stations. A total of 93 measurable drainage-basin characteristics were candidate independent variables. On the basis of several statistical parameters that were used to evaluate which combination of basin characteristics contribute the most to the predictive power of the equations, three drainage-basin characteristics were determined to be statistically significant predictors of the annual 7Q10: (1) total drainage area, (2) mean summer stream-gaging station precipitation from 1961 to 90, and (3) average mean annual basinwide temperature from 1961 to 1990. To evaluate the effectiveness of the stream-gaging network in providing regional streamflow data for the annual 7Q10, the computer program GLSNET (generalized-least-squares NETwork) was used to analyze the

    Objectives To identify: (a) the annual incidence of subsequent injury and injury related hospitalizations among individuals with pre-existing spinal cord injury (SCI) and (b) risk and protective behaviors associated with differential risk of injury. Design Longitudinal, mailed survey. Participants were enrolled in 1997-1998, with a follow-up conducted 10 years later. Setting Data were collected from participants identified from a specialty hospital and analyzed at a medical university in the Southeastern United States. Participants There were 1386 participants during the baseline enrollment, 821 of whom also participated in the 10-year follow-up. Inclusion criteria were: (1) traumatic SCI with residual impairment A-D, (2) non-surgical onset, (3) age 18 years or older, and (4) a minimum of 12 months post-SCI. Interventions Main Outcome Measures Number of injuries severe enough to require treatment in a clinic, emergency department, or hospital in the 12 months prior to the survey, and number of injury related hospitalizations. Predictor variables included selected items from the Behavioral Risk Factor Surveillance System, the Zuckerman-Kuhlman Personality Questionnaire, and prescription medication usage. Results Over 23% of participants reported at least 1 injury within the past year, an increase from that reported 10 years earlier by the same participants (19%), and 7% reported at least 1 injury related hospitalization. Those who reported a subsequent injury during the preliminary baseline data collection were about twice as likely to report at least 1 injury 10 years later. Binge drinking, psychotropic prescription medication use, and several personality characteristics were also related to injuries and/or injury hospitalization. Conclusions Risk of injury continues to be a significant concern in the years and decades after SCI onset. Behavioral and personality factors hold the key to prevention. PMID:21044720

    Within-city variation in air pollution has been associated with childhood asthma development, but findings have been inconsistent. We examined whether perinatal air pollution exposure affected asthma onset during "pre-school and "school age" periods in a population-based birth cohort.65,254 children born between 1999 and 2002 in the greater Vancouver metropolitan region were followed until age 10 years using linked administrative health databases. Asthma cases were sex- and age-matched to five randomly chosen controls. Associations between exposure to air pollutants estimated with different methods (interpolation (inverse-distance weighted (IDW)), land use regression, proximity) and incident asthma during the pre-school (0-5 years) and school age (6-10 years) periods were estimated with conditional logistic regression.6948 and 1711 cases were identified during the pre-school and school age periods, respectively. Following adjustment for birthweight, gestational period, household income, parity, breastfeeding at discharge, maternal age and education, asthma risk during the pre-school years was increased by traffic pollution (adjusted odds ratio using IDW method per interquartile increase (95% CI): nitric oxide 1.06 (1.01-1.11), nitrogen dioxide 1.09 (1.04-1.13) and carbon monoxide 1.05 (1.01-1.1)). Enhanced impacts were observed amongst low-term-birthweight cases. Associations were independent of surrounding residential greenness.Within-city air pollution variation was associated with new asthma onset during the pre-school years.

    The Centers for Disease Control and Prevention began funding a Smoke Alarm Installation and Fire Safety Education (SAIFE) program in 1998. This program involves the installation of lithium-powered "10-year" smoke alarms in homes at high risk for fires and injuries. This study aimed to (1) determine among original SAIFE homes if the lithium-powered alarms were still present and functional 8-10 years after installation and (2) understand factors related to smoke alarm presence and functionality. Data on a total of 384 homes and 601 smoke alarms in five states were collected and analyzed. Only one-third of alarms were still functional; 37% of installed alarms were missing; and 30% of alarms were present, but not functioning. Alarms were less likely to be functioning if they were installed in the kitchen and if homes had a different resident at follow-up. Of the 351 alarms that were present and had a battery at the time of the evaluation, only 21% contained lithium-powered batteries. Of these, 78% were still functioning. Programs that install lithium-powered alarms should use units that have sealed-in batteries and "hush" buttons. Additionally, education should be given on smoke alarm maintenance that includes a message that batteries in these alarms should not be replaced. Lithium-powered smoke alarms should last up to 10 years if maintained properly.

    The use of the Wampole Isolator 1.5-ml pediatric blood culture tube for the detection of fungemia in children was assessed by a 10-year retrospective review at two pediatric hospitals, The Hospital for Sick Children in Toronto, Canada, and the Children's Medical Center of Dallas, Texas. Over this period, a total of 9,442 pediatric Isolator specimens were processed, with yeast or yeast-like organisms recovered in 297 (3.1%) of the specimens (151 [1.6%] unique clinical episodes) and filamentous or dimorphic fungi recovered in 31 (0.3%) of the specimens (25 unique clinical episodes). Only 18 of the 151 clinical episodes of fungemia attributable to yeast were not detected by automated blood culture systems. The majority of isolated yeast were Candida spp., which were usually detected by automated systems, whereas the most common non-Candida yeast was Malassezia furfur, which the automated system failed to detect. Filamentous or dimorphic fungi were detected in 25 episodes, of which only 9 (36%) episodes were deemed clinically significant after chart review, indicating that in the majority of cases (16/25, 64%) fungal isolation represented contamination. In five of the nine clinically significant episodes, the isolated fungus (Histoplasma capsulatum, Coccidioides immitis/posadasii, Fusarium oxysporum, Aspergillus spp., and Bipolaris spp.) was also identified in other clinical specimens. Over the 10-year study period, the use of the pediatric Isolator system, at the discretion of the treating physician, only rarely provided useful clinical information for the diagnosis of fungemia in children, with the exception of M. furfur and possibly endemic mycoses.

    To determine the optimal storage method and longest possible storage period of Phyllospadix japonicus seeds, we examined post-storage germination rates using different storage methods and periods for P. japonicus seeds harvested in Korean coastal waters. P. japonicus seeds are classified as recalcitrant seeds with an average moisture content of 45.4%. Germination rates of P. japonicus seeds stored in seawater at 4 °C, seawater at room temperature with air supply, and an aquarium with continuous seawater circulation ranged from 35.0% to 43.5%, whereas seeds stored in seawater at 30°C, a refrigerator at -20°C, and a desiccator at room temperature did not germinate. Seeds stored at 4°C maintained germination rates of 72.5˜73.0% until 30 days of storage, but showed rapidly decreasing germination rates after 60 days and no germination after 180 days. Since few studies have investigated seed storage of P. japonicus, these results will serve as useful data for seed-based P. japonicus habitat restoration.

    Objective: Assess clinical results using two different protocols, 10 years after ACL reconstruction surgery with the central third of quadriceps muscle tendon (QT). Method: Between November /1997 and April/1998, 25 patients were submitted to 25 ACL reconstructions with QT by transtibial technique. The bone portion of the graft was fixated on femoral tunnel with interference screw and the tendinous portion of tibial tunnel with screw with washer. Two patients injured the new when playing soccer. Six patients were not available for follow-up (24%). Seventeen patients were evaluated, 15 men and two women, with mean age at surgery time of 28.53 ± 6.64 years. All patients were examined at six months, one year, and ten years after surgery. Clinical evaluation was made by the Lysholm scale, and the knee evaluation, with the Hospital for Special Surgery scale. Results: The patients had their injuries operated after 9.87 ± 14.42 months of the accident. According to Lysholm scale, the results at the end of the first year were 98.71 ± 2.47 and, after 10 years, 97.35 ± 3.12. Using the Hospital for Special Surgery scale, the mean score was 95.07 ± 5.23 in one year, and 94.87 ± 4.16 in 10 years. All patients returned to their professional activities with the same previous status. Fifteen (88.24%) patients were able to return to their sports activities, one by modifying the practice, while another one switched to another sport. No patient complained of pain on the donor area in the medium and long term. The sports return rate was excellent, and no changes were found on the femoropatellar joint. PMID:27022511

    Background: Little is known about employment outcomes after breast cancer (BC) beyond the first years after treatment. Methods: Employment outcomes were compared with a general population comparison group (N=91 593) up to 10 years after BC for 26 120 patients, diagnosed before age 55 between 2000–2005, with income and social benefits data from Statistics Netherlands. Treatment effects were studied in 14 916 patients, with information on BC recurrences and new cancer events. Results: BC survivors experienced higher risk of losing paid employment (Hazard Ratio (HR): 1.6, 95% Confidence Interval (95% CI) 1.4–1.8) or any work-related event up to 5–7 years (HR 1.5, 95% CI 1.3–1.6) and of receiving disability benefits up to 10 years after diagnosis (HR 2.0, 95% CI 1.6–2.5), with higher risks for younger patients. Axillary lymph node dissection increased risk of disability benefits (HR 1.5, 95% CI 1.4–1.7) or losing paid employment (HR 1.3, 95% CI 1.2–1.5) during the first 5 years of follow-up. Risk of disability benefits was increased among patients receiving mastectomy and radiotherapy (HR 1.2; 95% CI 1.1–1.3) and after chemotherapy (HR 1.7; 95% CI 1.5–1.9) during the first 5 years after diagnosis. Conclusions: BC treatment at least partly explains the increased risk of adverse employment outcomes up to 10 years after BC. PMID:26757424

  16. Cutoff radius effect of the isotropic periodic sum method in homogeneous system. II. Water.

    PubMed

    2010-07-07

    Molecular dynamics simulation has been applied for water to compare the isotropic periodic sum (IPS) method [X. Wu and B. R. Brooks, J. Chem. Phys. 122, 044107 (2005)] with the Ewald sum based on the diffusion coefficient and liquid structure. The IPS method gives a good estimation for the self-diffusion coefficient at a cutoff radius, r(c), greater than 2.2 nm; however, the radial distribution function g(r) has a notable deviation. The peak of this deviation appears at specific intermolecular distances which are near each cutoff radius and decrease in proportion to the inverse of the cube of r(c). Thus the deviation becomes insignificant (less than 1%) at r(c) greater than 2.2 nm. The distance dependent Kirkwood factor G(k)(r) was also calculated, and since the truncation of a long-range interaction of the cutofflike method (such as cutoff with or without the switch function and the reaction field) shows serious shortcomings for dipole-dipole correlations in bulk water systems, this was observed by comparing the shape to that of the Ewald sum [Y. Yonetani, J. Chem. Phys. 124, 204501 (2006); D. van der Spoel and P. J. van Maaren, J. Chem. Theory Comput. 2, 1 (2006)]. The G(k)(r) of cutofflike method greatly deviate from that of the Ewald sum. However, the discrepancy of G(k)(r) for the IPS method was found to be much less than that of other typical cutofflike methods. In conclusion, the IPS method is an adequately accurate technique for estimating transport coefficients and the liquid structure of water in a homogeneous system at long cutoff distances.

    The number of channels used for polysomnographic recording frequently causes difficulties for patients because of the many cables connected. Also, it increases the risk of having troubles during recording process and increases the storage volume. In this study, it is intended to detect periodic leg movement (PLM) in sleep with the use of the channels except leg electromyography (EMG) by analysing polysomnography (PSG) data with digital signal processing (DSP) and machine learning methods. PSG records of 153 patients of different ages and genders with PLM disorder diagnosis were examined retrospectively. A novel software was developed for the analysis of PSG records. The software utilizes the machine learning algorithms, statistical methods, and DSP methods. In order to classify PLM, popular machine learning methods (multilayer perceptron, K-nearest neighbour, and random forests) and logistic regression were used. Comparison of classified results showed that while K-nearest neighbour classification algorithm had higher average classification rate (91.87%) and lower average classification error value (RMSE = 0.2850), multilayer perceptron algorithm had the lowest average classification rate (83.29%) and the highest average classification error value (RMSE = 0.3705). Results showed that PLM can be classified with high accuracy (91.87%) without leg EMG record being present. PMID:27213008

This method allows to obtain information about the presence of propagating and non-propagating waves in the data observation (cube images), and localize them precisely in time as well in space. We tested the algorithm and found that the results of coronal waves detection are consistent with those obtained by visual inspection. For fast exploration of the data cube, in addition, we applied early-developed Period- Map analysis. This method based on the Fast Fourier Transform and allows on initial stage quickly to look for "hot" regions with the peak harmonic oscillations and determine spatial distribution at the significant harmonics. We propose the detection procedure of coronal waves separate on two parts: at the first part, we apply the PeriodMap analysis (fast preparation) and than, at the second part, use information about spatial distribution of oscillation sources to apply the PWF-method (slow preparation). There are two possible algorithms working with the data: in automatic and hands-on operation mode. Firstly we use multiply PWF analysis as a preparation narrowband maps at frequency subbands multiply two and/or harmonic PWF analysis for separate harmonics in a spectrum. Secondly we manually select necessary spectral subband and temporal interval and than construct narrowband maps. For practical implementation of the proposed methods, we have developed the remote data processing system at Institute of Solar-Terrestrial Physics, Irkutsk. The system based on the data processing server - http://pwf.iszf.irk.ru. The main aim of this resource is calculation in remote access through the local and/or global network (Internet) narrowband maps of wave's sources both in whole spectral band and at significant harmonics.

    Estimation of the free core nutation (FCN) period is a challenging prospect. Mostly, two methods, one direct and one indirect, have been applied in the past to address the problem by analyzing the Earth orientation parameters observed by the very long baseline interferometry. The indirect method estimates the FCN period from resonance effects of the FCN on forced nutation terms, whereas the direct method estimates the FCN period using the Fourier Transform (FT) approach. However, the FCN period estimated by the direct FT technique suffers from the non-stationary characteristics of celestial pole offsets (CPO). In this study, the FCN period is estimated by another direct method, i.e., the sliding-window complex least-squares fit method (SCLF). The estimated values of the FCN period for the full set of 1984.0-2014.0 and four subsets (1984.0-2000.0, 2000.0-2014.0, 1984.0-1990.0, 1990.0-2014.0) range from -428.8 to -434.3 mean solar days. From the FT to the SCLF method, the estimate uncertainty of the FCN period falls from several tens of days to several days. Thus, the SCLF method may serve as an independent direct way to estimate the FCN period, complementing and validating the indirect resonance method that has been frequently used before.

    Context: Fitness testing is used frequently in many areas of physical activity, but the reliability of these measurements under real-world, practical conditions is unknown. Objective: To evaluate the reliability of specific fitness tests using the methods and time periods used in the context of real-world sport and occupational management. Design: Cohort study. Setting: Eighteen different Cirque du Soleil shows. Patients or Other Participants: Cirque du Soleil physical performers who completed 4 consecutive tests (6-month intervals) and were free of injury or illness at each session (n = 238 of 701 physical performers). Intervention(s): Performers completed 6 fitness tests on each assessment date: dynamic balance, Harvard step test, handgrip, vertical jump, pull-ups, and 60-second jump test. Main Outcome Measure(s): We calculated the intraclass coefficient (ICC) and limits of agreement between baseline and each time point and the ICC over all 4 time points combined. Results: Reliability was acceptable (ICC > 0.6) over an 18-month time period for all pairwise comparisons and all time points together for the handgrip, vertical jump, and pull-up assessments. The Harvard step test and 60-second jump test had poor reliability (ICC < 0.6) between baseline and other time points. When we excluded the baseline data and calculated the ICC for 6-month, 12-month, and 18-month time points, both the Harvard step test and 60-second jump test demonstrated acceptable reliability. Dynamic balance was unreliable in all contexts. Limit-of-agreement analysis demonstrated considerable intraindividual variability for some tests and a learning effect by administrators on others. Conclusions: Five of the 6 tests in this battery had acceptable reliability over an 18-month time frame, but the values for certain individuals may vary considerably from time to time for some tests. Specific tests may require a learning period for administrators. PMID:22488138

    Background Chronic stress frequently manifests with anxiety and/or depressive symptomatology and may have detrimental cardiometabolic effects over time. As such, recognising the potential links between stress-related psychological disorders and cardiovascular disease (CVD) is becoming increasingly important in cardiovascular epidemiology research. The primary aim of this study was to explore prospectively potential associations between clinically relevant depressive symptomatology and anxiety levels and the 10-year CVD incidence among apparently healthy Greek adults. Design A population-based, health and nutrition prospective survey. Methods In the context of the ATTICA Study (2002-2012), 853 adult participants without previous CVD history (453 men (45 ± 13 years) and 400 women (44 ± 18 years)) underwent psychological evaluations through validated, self-reporting depression and anxiety questionnaires. Results After adjustment for multiple established CVD risk factors, both reported depression and anxiety levels were positively and independently associated with the 10-year CVD incidence, with depression markedly increasing the CVD risk by approximately fourfold (adjusted odds ratio (95% confidence interval) 3.6 (1.3, 11) for depression status; 1.03 (1.0, 1.1) for anxiety levels). Conclusions Our findings indicate that standardised psychological assessments focusing on depression and anxiety should be considered as an additional and distinct aspect in the context of CVD preventive strategies that are designed and implemented by health authorities at the general population level.

    The periodic Anderson model (PAM) in the U→∞ limit has been studied in a previous work employing the cumulant expansion with the hybridization as perturbation (Figueira et al., Phys. Rev. B 50 (1994) 17 933). When the total number of electrons Nt is calculated as a function of the chemical potential μ in the “chain approximation” (CHA), there are three values of the chemical potential μ for each Nt in a small interval of Nt at low T (Physica A 208 (1994) 279). We have recently introduced the “X-boson” method, inspired in the slave boson technique of Coleman, that solves the problem of nonconservation of probability (completeness) in the CHA as well as removing the spurious phase transitions that appear with the slave boson method in the mean field approximation. In the present paper, we show that the X-boson method solves also the problem of the multiple roots of Nt( μ) that appear in the CHA.

  3. A periodic energy decomposition analysis method for the investigation of chemical bonding in extended systems

    2015-05-21

    The development and first applications of a new periodic energy decomposition analysis (pEDA) scheme for extended systems based on the Kohn-Sham approach to density functional theory are described. The pEDA decomposes the bonding energy between two fragments (e.g., the adsorption energy of a molecule on a surface) into several well-defined terms: preparation, electrostatic, Pauli repulsion, and orbital relaxation energies. This is complemented by consideration of dispersion interactions via a pairwise scheme. One major extension toward a previous implementation [Philipsen and Baerends, J. Phys. Chem. B 110, 12470 (2006)] lies in the separate discussion of electrostatic and Pauli and the addition of a dispersion term. The pEDA presented here for an implementation based on atomic orbitals can handle restricted and unrestricted fragments for 0D to 3D systems considering periodic boundary conditions with and without the determination of fragment occupations. For the latter case, reciprocal space sampling is enabled. The new method gives comparable results to established schemes for molecular systems and shows good convergence with respect to the basis set (TZ2P), the integration accuracy, and k-space sampling. Four typical bonding scenarios for surface-adsorbate complexes were chosen to highlight the performance of the method representing insulating (CO on MgO(001)), metallic (H{sub 2} on M(001), M = Pd, Cu), and semiconducting (CO and C{sub 2}H{sub 2} on Si(001)) substrates. These examples cover diverse substrates as well as bonding scenarios ranging from weakly interacting to covalent (shared electron and donor acceptor) bonding. The results presented lend confidence that the pEDA will be a powerful tool for the analysis of surface-adsorbate bonding in the future, enabling the transfer of concepts like ionic and covalent bonding, donor-acceptor interaction, steric repulsion, and others to extended systems.

    Objective To examine whether having family meals as an adolescent protects against becoming overweight or obese 10 years later as a young adult. Study design Data from Project EAT-III, a longitudinal cohort study with emerging young adults, were used. At baseline (1998-1999) adolescents completed surveys in middle or high schools and at 10-year follow-up (2008-2009) surveys were completed online or via mailed surveys. Young adult participants (n=2117) were racially/ethnically and socioeconomically diverse (52% minority; 38% low income) between the ages of 19-31 (mean age=25.3; 55% female). Logistic regression was used to associate weight status at follow-up with family meal frequency 10-years earlier during adolescence, controlling and testing for interactions with demographic characteristics. Results All levels of baseline family meal frequency (i.e., 1-2, 3-4, ≥5 family meals/week) during adolescence were significantly associated with reduced odds of overweight or obesity ten years later in young adulthood as compared with never having family meals as an adolescent. Interactions by race indicated that family meals had a stronger protective effect for obesity in black versus white young adults. Conclusions Family meals during adolescence were protective against the development of overweight and obesity in young adulthood. Professionals who work with adolescents and parents may want to strategize with them how to successfully carry out at least one to two family meals per week in order to protect adolescents from overweight or obesity in young adulthood.

    Precisely four hundred years ago, Italian scientist Galileo's observations of the heavens forever and profoundly altered the way we view our place in the Universe. Throughout 2009, children across Wyoming are joining in a United Nations proclaimed International Year of Astronomy celebration. To commemorate 400 years of the telescope in advancing our understanding of the Universe through astronomy, our goal is that every 10-year old child in Wyoming will experience the excitement and wonder of looking through their very own telescope to observe majestic rings surrounding Saturn, deep craters on the Moon, countless stars lining the Milky Way, brilliant phases of Venus, and orbiting moons of Jupiter. This is being accomplished by a massive, state-wide collaborative effort bringing the collective energy and enthusiasm of professional scientists, amateur astronomers, local teachers, and community outreach enthusiasts together to spark an interest in science among Wyoming's children. Our strategy to bring a telescope to every Wyoming 10-year old child started first with a major year-long fundraising campaign. We estimate the cost of an individual telescope, constructed specifically for the 2009 International Year of Astronomy celebration, to be approximately $13 per child. With 6,489 (in 2007) 10-year old children in Wyoming, this amounts to less than $100,000 as a fund raising goal. University of Wyoming faculty are training teachers in how to use telescopes and how to integrate the excitement of astronomy across the curriculum. To teach children how to use their telescopes, volunteers from around the state are hosting star parties at schools, county fairs, and other regularly scheduled community celebrations.

    This case report describes the treatment of two immature maxillary central incisors in a 7-year-old female patient. She suffered complicated crown fracture because of trauma, and the root formation was incomplete. White mineral trioxide aggregate (MTA) was selected as the pulp-capping material after cervical pulpotomy to preserve the pulp tissue vitality and achieve maturogenesis. Follow-up evaluations showed successful treatment in terms of preservation of pulp vitality and demonstrated marked continuous physiological root development. During 10 years of follow-up, both teeth were clinically asymptomatic, and radiographic evaluations showed apparent root regeneration with apical root-end closure without pulp or periapical pathosis.

    Peroral endoscopic myotomy (POEM) is a new endoscopic treatment for achalasia with very good short-term results in adults. Data about POEM in pediatric patients are missing. We present the case of a 10-year-old male patient with type I (classic) achalasia, successfully treated with POEM. The procedure was accomplished in a similar fashion to the technique used in adults. Short-term results were fine, with a complete control of dysphagia and absence of reflux. We suggest that POEM is a suitable option in pediatric patients-similar to adults-but long-term results must be awaited.

    Malignant neoplasms of the pancreas are extremely rare in children and only represent a small percentage of pediatric cancer-related deaths. The paucity of cases reported in the literature, in addition to the lack of understanding of biologic behavior, has led to a lack of consensus concerning optimal management strategy. Presentation differs compared to adult counterparts and generally prognosis is improved even when lymph node metastases occur. Here we review the literature and report the case of a 10-year-old autistic female with a malignant nonfunctioning pancreatic endocrine neoplasm of the head of the pancreas successfully extirpated via pancreaticoduodenectomy.

    10 years after the preservice inspection in 1979, French legislation required the Fessenheim 1 900 MW reactor unit to undergo specific inspections necessitating a long-duration shut-down. EDF, the French Electricity Board, decided to take advantage of the shut-down to make major improvements to safety, fire detection and fire-fighting systems. Fessenheim 1 was shut down on April 7th 1989 and reconnected to the grid on October 14th in the same year. The overall operation was brought to a successful conclusion. This paper reviews the objectives and preparatives for the operation, describes the key phases and summarizes the main benefits.

    Intraneural ganglion cysts are uncommon cystic lesions of peripheral nerves that are typically encountered in adults. In the lower extremity, the peroneal nerve is most frequently affected with involvement of the tibial nerve much less common. This article describes a tibial intraneural ganglion cyst in a 10-year-old boy. Although extremely rare, intraneural ganglion cysts of the tibial nerve should be considered when a nonenhancing cystic structure with intra-articular extension is identified along the course of the nerve. This report also details the unsuccessful attempt at percutaneous treatment with US-guided cyst aspiration and steroid injection, an option recently reported as a viable alternative to open surgical resection.

    Introduction Managing postoperative pain in patients undergoing minimally invasive pectus excavatum repair (Nuss procedure) is challenging but essential in facilitating ambulation and minimizing the length of stay. Although multiple epidural regimens with varying opioids are presently used for pain management, there is currently no clinical consensus regarding which epidural regimen provides the best analgesia outcomes with the fewest side effects. This 10-year retrospective cohort study was performed to compare the quality of analgesia and the incidence of side effects associated with the three most common epidural regimens used at a tertiary care children’s hospital, in patients undergoing the Nuss procedure. Methods Seventy-two pediatric patients were identified as having been treated with one of three epidural regimens for postoperative pain management following the Nuss procedure: Group A (n=12) received 0.125% bupivacaine and 5 µg/mL fentanyl, Group B (n=21) received 0.125% bupivacaine and 10 µg/mL hydromorphone, and Group C (n=39) received 0.1% ropivacaine and 20 µg/mL hydromorphone. Our primary outcome was maximal daily pain scores (numerical rating scale 0–10), with an analytical focus on postoperative day 1 scores. The primary outcome was analyzed using linear regression. The secondary outcomes included the length of stay, side-effect profiles as reflected by the number of treatments for nausea and pruritus, pain scores according to epidural site insertion, occurrence of breakthrough pain, and presence of severe pain throughout their hospital stay. Secondary outcomes were analyzed using linear or logistic regression adjusted for pain scores at baseline. The criterion for statistical significance was set a priori at alpha =0.05. Results Group A had significantly higher day-1 pain scores (score 5.42/10) than Group B (4.52/10; P=0.030) and Group C (4.49/10; P=0.015) after adjusting for baseline pain and age.

    The light variability is one of the main characteristics of blazar objects. Because of the complexity of their light curves, the present periodicity analysis methods are not yet perfect. Based on the modern spectral estimate theory, this paper has described in details the principles of the maximum entropy spectral estimate and autoregressive (AR) spectral estimate, analyzed the effect of the order number selection on the resultant model. Applying these methods to the periodicity analysis of the quasar 3C 279 and BL Lac object OJ 287, their light periods are obtained to be 7.14 and 11.76 yr, respectively. As is verified by experiments, the AR spectral estimate has a high resolution and is a rather good periodicity analysis method. Finally, the items noteworthy for the application of these spectrum estimation methods to the periodicity analysis of the light variations of blazars are mentioned.

    Research on asthma costs often focuses on estimating average asthma costs. Trends in asthma costs and patterns of medication use, especially for those who have been followed up and under treatment, have received much less attention. This study's objective was to document asthma costs over time for asthma patients who are enrolled in an asthma care programme in Singapore and to identify its predictors, using a 10-year longitudinal dataset.The study population comprised different cohorts of 939 asthma patients entering the programme at different times during 2004-2013. Average asthma costs were estimated and the trends over time examined graphically, within and across patient cohorts. Regression analyses were conducted to examine cost predictors, with a focus on the relationship between risk factors at programme enrolment and subsequent asthma costs.The results indicate that 10-year average annual asthma cost was GBP 341 per patient. The main drivers of costs were asthma medications and consultation fees. Use of combined inhaled corticosteroid/long-acting β-agonist medications increased over time, but this was accompanied by declines in controller drug use, doctor visits and total asthma drug costs. Obesity, smoking and asthma severity were the main predictors of subsequent asthma costs, especially for females.

    In previous studies we created 8 new versions of a single face: 4 differed only in the spacing among features and 4 differed in the shape of the eyes and mouth. Compared to the spacing set, results for this feature set indicated little impairment by inversion, earlier adult-like accuracy (Mondloch et al, 2002 Perception 31 553-566), and normal performance after a history of early visual deprivation from bilateral congenital cataract (Le Grand et al, 2001 Nature 410 890, 412 786). Here we addressed the possibility that this pattern might have resulted from our having inadvertently selected easily discriminated features or including some faces with make-up. We created 20 featural versions of a single female face and asked adults, 10-year-old children, and patients treated for bilateral congenital cataract to make same/different judgments for 120 pairings (half different). The results confirm that adults easily discriminate facial features, even after early visual deprivation from cataract, and that inversion has only a small effect. By the age of 10 years, children are close to, but not quite at, adult levels of accuracy. The previous findings cannot be attributed to our having inadvertently created a feature set that was unusually easy to discriminate.

  19. Evaluation of 6 and 10 Year-Old Child Human Body Models in Emergency Events

    Emergency events can influence a child’s kinematics prior to a car-crash, and thus its interaction with the restraint system. Numerical Human Body Models (HBMs) can help understand the behaviour of children in emergency events. The kinematic responses of two child HBMs–MADYMO 6 and 10 year-old models–were evaluated and compared with child volunteers’ data during emergency events–braking and steering–with a focus on the forehead and sternum displacements. The response of the 6 year-old HBM was similar to the response of the 10 year-old HBM, however both models had a different response compared with the volunteers. The forward and lateral displacements were within the range of volunteer data up to approximately 0.3 s; but then, the HBMs head and sternum moved significantly downwards, while the volunteers experienced smaller displacement and tended to come back to their initial posture. Therefore, these HBMs, originally intended for crash simulations, are not too stiff and could be able to reproduce properly emergency events thanks, for instance, to postural control. PMID:28099505

    We describe a case of stump appendicitis with the formation of abdominal abscesses in a 41-year-old patient 10 years prior appendectomy. The patient consulted with fever (38.1 °C) and abdominal pain, located at the right iliac fossa. Imaging studies showed signs of abscesses, located at the right iliac fossa, without clear origin of these abscesses. The abscesses were drained through diagnostic laparoscopy, no bowel perforation or clear origin of the abscedation was found during laparoscopy. During postoperative stay, the inflammatory parameters rose and the abscesses reoccurred. Re-laparoscopy was performed, the abscesses were drained and on careful inspection and adhesiolysis, a perforated stump appendicitis was revealed, covered underneath layers of fibrous tissue. Stump appendicitis is a rare complication seen after appendectomy and is generally not considered a possible etiology in patients presenting with fever and right iliac fossa abdominal pain with a history of appendectomy. This often delays the correct diagnosis and results in an associated increased incidence of complications. We describe a case of stump appendicitis occurring 10 years after initial appendectomy.

    The causes and mechanism behind motor complications in Parkinson disease (PD) are still a subject of debate. Several factors including age at onset, evolution in years, and initial medication can influence the onset and severity of motor complications in PD.We studied patients with recent diagnosis of PD who were followed up prospectively for 10 years. Analysis included the progression of these patients, as measured by the Unified Parkinson Disease Rating Scale scores and the presence of motor complications (motors fluctuations, dyskinesias, and gait freezing) over time. The patient group was studied as a whole and by subgroups classified according to age at onset, initial treatment, and sex.By the end of the first decade, most patients exhibited dyskinesias (91%), motor fluctuations (62%), and freezing of gait (68%). An association was found between several patients' characteristics and presence of motor complications by 5 years, though not after 10 years of follow up. The apparition of motor fluctuations was mainly related to initial treatment (odds ratio [OR], 3.87). The development of dyskinesias was linked to initial treatment (OR, 8.31), age at onset (OR, 0.90), and sex (OR, 12.87).

    This study was conducted among two groups of 105 children in a hospital in Yaoundé, Cameroon, to determine the causes of anaemia in children aged 5- 10-years-old. The study group included children presenting clinical evidence of anaemia while the control group was made of children without anaemia. Both sets of children were matched for neighbourhoods within the city of Yaoundé. Each child had a complete physical examination, full blood count, haemoglobin electrophoresis, reticulocyte counts, and stool samples examined for parasites and hemoparasites. The mean haemoglobin level was 7.77 +/- 1.54 g/dL in the study group and 12.37 +/- 1.23 in the control group. The anaemia was mainly normocytic, normochromic and regenerative in the study group, usually associated with evidence of haemolysis. Patients with homozygous sickle cell disease were found only in the study group (n = 13; 12.3%). Malaria parasites were noted in 89 children (84.7%) in the study group, compared with 34 (32.4%) in the control group (p = 0.0004). Prevalence of intestinal parasites was similar in both groups (50.8%). Protein-calorie malnutrition was rare and was not associated with anemia. We conclude that both malaria and sickle cell anaemia play an important role in anaemia in children aged 5-10 years.

    Since launch in May 2002, Aqua MODIS has successfully operated for nearly 10 years, continuously collecting global datasets for scientific studies of key parameters of the earth's land, ocean, and atmospheric properties and their changes over time. The quality of these geophysical parameters relies on the input quality of sensor calibrated radiances. MODIS observations are made in 36 spectral bands with wavelengths ranging from visible (VIS) to longwave infrared (LWIR). Its reflective solar bands (RSB) are calibrated using data collected from its on-board solar diffuser and regularly scheduled lunar views. The thermal emissive bands (TEB) are calibrated using an on-board blackbody (BB). The changes in the sensor's spectral and spatial characteristics are monitored by an on-board spectroradiometric calibration assembly (SRCA). This paper presents an overview of Aqua MODIS 10-year on-orbit operation and calibration activities, from launch to present, and summarizes its on-orbit radiometric, spectral, and spatial calibration and characterization performance. In addition, it will illustrate and discuss on-orbit changes in sensor characteristics and corrections applied to continuously maintain the sensor level 1B (L1B) data quality, as well as lessons learned that could benefit future calibration efforts.

    The first joint meeting between NASA, KNMI and FMI scientists was held on 13 & 14 June, 2000, almost exactly 10 years ago. NASA had recently selected 14 US scientists to work on instrument calibration, science algorithms, and validation activities related to the Ozone Monitoring Instrument (OMI) that we being built by collaboration between the Netherlands and Finland for flight on NASA's EOS Aura satellite. The progress on this project had been remarkable for a space based instrument. Only two years before this meeting my colleague Ernest Hilsenrath and I had visited Netherlands at the invitation of Fokker Space to persuade KNMI management to collaborate with NASA on this mission. And only 4 years after the first science meeting was held OMI was lunched on the Aura spacecraft. Next month will be the 6 th anniversary of this launch and very successful operation of OMI. All this was possible because of the leadership from Dr. Hennie Kelder and KNMI management who in 1998 saw the opportunity for Netherlands in the mission and stepped up to the challenge by creating a young and talented team of scientists at KNMI under the leadership of Dr. Pieterenel Levelt. This vision has now put Netherlands as the leading country in the world in monitoring air quality from space. Recent selection of TROPOMI by ESA attests to the success of this vision. I will present some selected highlights of our very successful collaboration on this project over the past 10 years.

    The development of contextual cueing specifically in relation to attention was examined in two experiments. Adult and 10-year-old participants completed a context cueing visual search task (Jiang & Chun, The Quarterly Journal of Experimental Psychology, 54A(4), 1105-1124, 2001) containing stimuli presented in an attended (e.g., red) and unattended (e.g., green) color. When the spatial configuration of stimuli in the attended and unattended color was invariant and consistently paired with the target location, adult reaction times improved, demonstrating learning. Learning also occurred if only the attended stimuli's configuration remained fixed. In contrast, while 10 year olds, like adults, showed incrementally slower reaction times as the number of attended stimuli increased, they did not show learning in the standard paradigm. However, they did show learning when the ratio of attended to unattended stimuli was high, irrespective of the total number of attended stimuli. Findings suggest children show efficient attentional guidance by color in visual search but differences in contextual cueing.

    Emergency events can influence a child's kinematics prior to a car-crash, and thus its interaction with the restraint system. Numerical Human Body Models (HBMs) can help understand the behaviour of children in emergency events. The kinematic responses of two child HBMs-MADYMO 6 and 10 year-old models-were evaluated and compared with child volunteers' data during emergency events-braking and steering-with a focus on the forehead and sternum displacements. The response of the 6 year-old HBM was similar to the response of the 10 year-old HBM, however both models had a different response compared with the volunteers. The forward and lateral displacements were within the range of volunteer data up to approximately 0.3 s; but then, the HBMs head and sternum moved significantly downwards, while the volunteers experienced smaller displacement and tended to come back to their initial posture. Therefore, these HBMs, originally intended for crash simulations, are not too stiff and could be able to reproduce properly emergency events thanks, for instance, to postural control.

    Men assigned to units producing ethylene oxide by the chlorohydrin or direct oxidation processes and to other departments using ethylene oxide in two chemical plants were followed up for mortality from 1940 to 1988 (n = 1896). Based on findings from a previous study of these workers to the end of 1978, which identified confounding exposures, workers assigned to one unit with low ethylene oxide exposure potential were excluded (n = 278). Average duration of exposure was over five years and average follow up was 27 years, with all subjects at least 10 years from first exposure. The data did not support associations of ethylene oxide with all cancer types combined, leukaemia, non-Hodgkin's lymphoma, or brain, pancreatic, or stomach cancers. There were also no duration-response trends. The standardised mortality ratio (SMR) for total cancer was 86 (95% confidence interval 71-104) and did not increase for those hired the earliest and with long duration assignments. The results of this 10 year update and those of other recent studies of ethylene oxide workers do not confirm findings from animal studies and are not consistent with the earliest results reported among ethylene oxide workers.

    The issue of health inequalities has steadily gained attention in South Korea, as income inequality widened and social polarization increased following the country's economic crisis in the late 1990s. While official figures indicate a general trend of worsening mental health, with rapidly rising rates of suicide and depression in particular, the extent of socio-economic inequality with respect to mental health problems has not been well elucidated. This study aimed to measure income-related inequalities in depression, suicidal ideation and suicide attempts in South Korea and to trace their changes over a 10-year period (1998-2007). The concentration index approach was employed to quantify the degree of income-related inequalities, using four waves of the Korea National Health and Nutrition Examination Survey data. The study found persistent pro-rich inequality in depression, suicidal ideation and suicide attempts over the past decade (i.e., individuals with higher incomes were less likely to have these conditions). The inequalities actually doubled over this period. These findings imply a need for expanded social protection policies for the less privileged in the population.

    The Ozone Monitoring Instrument (OMI) aboard the Aura satellite recorded the 10-year (2005-2014) of tropospheric nitrogen dioxide (NO2) vertical column density (VCD) data. The data set taken over East Asia was analyzed to estimate linear trends on national and grid bases for two periods of 2005-2011 and 2011-2014. The most striking features are leveling-off or decreasing trends seen in NO2 VCDs over China for 2011-2014 after continuous increases for 2005-2011. In particular, a significant reduction by ~14% occurred from 2013 through 2014, attaining to the level of 2009. The grid-basis trend analysis implies that the turnaround seen in the trends occurred on a province or larger spatial scale and was likely due mainly to the technical improvement such as the widespread use of de-NOx units. Another prominent features are seen in Japan, where NO2 VCDs decreased at a rate of ~4% per year from 2005 to 2011. The rate was almost unchanged between the two periods 2005-2011 and 2011-2014, while the significant power substitution of thermal power generation for the nuclear power generation took place in Japan after 2011, when a massive earthquake occurred off the Pacific coast of northern Japan. This reflects a less contribution of NOx emissions from the power plant sector than that from the transport sector in the Pacific Belt Zone lying over metropolitan areas.

    The relationship between the lunar cycle and the frequency of contact with community-based psychiatric services was assessed using the South Verona Psychiatric Case Register data. For each day of the study period (January 1982-December 1991) we recorded the number of contacts made by South Verona residents with psychiatric services and the corresponding day of the lunar cycle. First, the synodic month was divided into four interval phases (usually called new moon, first quarter, full moon and third quarter), and interphase differences in the mean number of contacts were tested using one-way analysis of variance. Second. the null hypothesis of no relationship between the lunar cycle and the frequency of contact with psychiatric services was tested against the alternative hypothesis of a sinusoidal distribution according to the lunar phase. The average number of contacts with psychiatric services on each day of the lunar cycle over the 10-year period was obtained and a sine-wave curve was fitted to the data. Both for total and drop-in contacts, no significant differences in mean number of contacts were found between the four interval phases of the synodic month (new moon, first quarter, full moon and third quarter). Similarly, no significant results were found by setting the expected surge in consultations at 1-3 days after the full moon and the period of the sine-wave curve equal to 30 days. When the period of the sine-wave curve was allowed to vary in order to fit the data best, none of the statistical tests reached the level of significance required to dismiss the possibility of false-positive results. These findings did not support the theory that a relationship exists between the lunar cycle and the frequency of contact with community-based psychiatric services.

  11. Cold start extra emissions as a function of engine stop time: Evolution over the last 10 years

    Cars with catalysts show a significant increase in exhaust emissions at engine start. These extra emissions are expressed as the difference, over a particular driving cycle, between emissions generated when the vehicle is started and when the engine or the catalyst are stably warm. Experimental data, suitable for the assessment of cold start emissions, are usually available for completely cooled engines. Most results originate from tests at ambient temperature of 20-30 °C and with an engine stop time of at least 12 h. On the other hand, data including shorter stop times are very rare. The present work investigates the influence of exhaust emissions with shorter stop times, i.e. 0.5, 1, 2 and 4 h. The main goal consists in the comparison of emissions exhausted by recent car models (Euro-4) against emissions assessed in the framework of a similar campaign 10 years ago (FAV1/Euro-1 vehicles). A short survey of the current extra emission estimation methods is presented in this paper. It is shown that some methods are not suited for providing correct estimations in all cases. We discuss the fact that different estimation methods can show either similar or completely different results depending on the evolution behaviour of the hot emissions. Due to new technologies, e.g. the catalyst and improved engine control algorithms, emissions have been considerably reduced over the last 10 years. In this study it is determined how the relative extra emissions, i.e. extra emissions relative to the extra emissions for the standard stop time of 12 h, expressed as a function of stop time have changed. We may claim with caution that for medium stop times of 0.5-4 h the average relative extra emissions of Euro-4 vehicles are well below the average of the relative extra emissions of Euro-1 vehicles.

    A nutrition assessment of 16 members of a community of lacto-ovo vegetarian Trappist monks was conducted in 1977. Plasma zinc was found to be low-normal, which was attributed primarily to high intakes of phytate-containing foods. Individual and group counseling were instituted over a 10-year period in an attempt to emphasize the importance of wise food selection within the constraints of lacto-ovo vegetarianism. In 1987, a more comprehensive nutrition assessment of 21 members of the same community was performed. Food composites were analyzed, and 3-day instead of 24-hour dietary records were kept. Intakes of phytate-containing foods had decreased from 4,569 to 972 mg/day; intake of dietary zinc had increased from 7.4 to 9.7 mg/day; and the phytate:zinc molar ratio had decreased from 67 to 14 for the years 1977 and 1987, respectively. An analyzed phytate:zinc molar ratio of 9.8 and an analyzed phytate x calcium:zinc molar ratio of 0.3 were representative of the 1987 community. Both were within normal ranges. Plasma zinc had risen to upper-normal levels. The 1987 nutrition assessment showed that it is possible to be adequately nourished with a lacto-ovo vegetarian diet provided one has proper knowledge of the phytate-containing foods and the methods for compensating with foods of greater mineral density (primarily zinc).

    Objectives Orofacial cysts are broadly divided into odontogenic and nonodontogenic types, epithelial or non-epithelial, and developmental or inflammatory in origin. The odontogenic cyst is an osseous-destructive lesion that most commonly affects the jaw. It is formed by activation of odontogenic cell rests entrapped within the bone or gingival tissue of the jaws, such as the epithelial remains of Malassez, the dental lamina (cell rests of Serres), or the enamel organ. Methods We performed a retrospective study of all histologically diagnosed cysts of the orofacial region seen at the Maxillofacial clinic of the Ahmadu Bello University Teaching Hospital, Nigeria, between January 2003 and December 2012. Results Over the 10-year study period, 64 cases of cystic lesions of the orofacial region were seen in 1162 pathological specimens, representing 5.5%. Of these, there were 35 (54.7%) lesions in males and 29 (45.3%) in females giving a M:F ratio of 1.2:1. The age of the patients ranged from 4–64 years old (mean = 26.3 years). Dentigerous cyst (n = 21; 32.8%) was the most predominant lesion followed by periodontal (n = 12; 18.8%) and radicular cysts (n = 10; 15.6%). Conclusions Cysts of the orofacial region are common in this environment and like previous studies from Nigeria odontogenic cysts are not uncommon, the most predominant being dentigerous cysts.

    Because of the increased volume of information available to physicians from advanced medical technology, the obtained information of each symptom with respect to a disease may contain truth, falsity and indeterminacy information. Since a single-valued neutrosophic set (SVNS) consists of the three terms like the truth-membership, indeterminacy-membership and falsity-membership functions, it is very suitable for representing indeterminate and inconsistent information. Then, similarity measure plays an important role in pattern recognition and medical diagnosis. However, existing medical diagnosis methods can only handle the single period medical diagnosis problem, but cannot deal with the multi-period medical diagnosis problems with neutrosophic information. Hence, the purpose of this paper was to propose similarity measures between SVNSs based on tangent function and a multi-period medical diagnosis method based on the similarity measure and the weighted aggregation of multi-period information to solve multi-period medical diagnosis problems with single-valued neutrosophic information. Then, we compared the tangent similarity measures of SVNSs with existing similarity measures of SVNSs by a numerical example about pattern recognitions to indicate the effectiveness and rationality of the proposed similarity measures. In the multi-period medical diagnosis method, we can find a proper diagnosis for a patient by the proposed similarity measure between the symptoms and the considered diseases represented by SVNSs and the weighted aggregation of multi-period information. Then, a multi-period medical diagnosis example was presented to demonstrate the application of the proposed diagnosis method and to indicate the effectiveness of the proposed diagnosis method by the comparative analysis. The diagnosis results showed that the developed multi-period medical diagnosis method can help doctors make a proper diagnosis by the comprehensive information of multi-periods.

    Background. Childhood obesity is becoming a global epidemic which may result in increased morbidity and mortality during young adulthood. Objectives. To identify factors associated with overweight and that of obesity among Kuwaiti elementary male school children aged 6-10 years. Methods. Weights and heights of 662 students at a randomly selected school were collected to obtain body mass index (BMI). Results. The prevalence of overweight and obesity among the students were 20.2% and 16.8%, respectively. There were a variety of factors associated with overweight and obesity; however, having one or more obese brother, an unemployed father, or a high (>11) number of persons living at home was significantly associated with higher risk of overweight and obesity. Increased age and school level as well as having a chronic disease were associated with the risk of overweight. Conclusion. Health education programs for families should be implemented to help control overweight and obesity in Kuwaiti children.

    This article presents a case of a 10-year-old boy with a right acetabular fracture secondary to a direct blow to the pelvis and back. He sustained a right hip dislocation and transverse with posterior wall acetabular fracture with a nonconcentric hip joint after reduction. The fracture was treated with right labral and articular segment absorbable suture tie-down and relocation of the right hip into an anatomical position. At 32-month follow-up, the patient had returned to activities of daily living, he had a normal and symmetric gait pattern, and no pain on hip adduction, flexion, or internal rotation. This technique reduced the fracture and labrum, relocated the hip joint, and obviated the need for hardware removal that is typically needed in the pediatric population. This case is distinctive due to the patient's young age and treatment method, which has not been described previously for the treatment of this rare pediatric fracture.

    Summary Introduction Intra-uterine growth restriction (IUGR) is present in about 3–10% of live-born newborns and it is as high as 20–30% in developing countries. Since the 1990s, it has been known that abnormalities during foetal growth may result in cardiovascular disease, including hypertension in adulthood. Methods This study evaluated blood pressure parameters (using ambulatory blood pressure monitoring) in children aged six to 10 years old, born as small for gestational age (SGA), and compared them to their healthy peers born as appropriate for gestational age (AGA). Results In the SGA group, an abnormal blood pressure level (prehypertension or hypertension) was present significantly more often than in the AGA group (50 vs 16%, p < 0.01). This relationship also occurred in association with the type of IUGR (asymmetric p < 0.01, symmetric p < 0.05). Conclusion In SGA children, abnormal blood pressure values occurred more frequently than in AGA children. PMID:24844552

    Both the prevalence of cardiovascular risk factors and event rate are increased in patients with urolithiasis. Screening is recommended to all patients who have high cardiovascular risk. The aim of this study was to document 10-year risk of cardiovascular disease and mortality in asymptomatic patients with urolithiasis. Consecutive 200 patients with calcium oxalate urolithiasis were compared with 200 age- and sex-matched healthy controls. Ten-year cardiovascular disease risk was calculated with the Framingham Risk Score and mortality risk with SCORE risk score. Calcium, oxalate, and citrate excretion were studied as urinary stone risk factors. The results indicate that patients with urolithiasis had higher total cholesterol (p < 0.0001), lower HDL-cholesterol (p < 0.0001), and higher systolic blood pressure (p < 0.0001) and hsCRP (p < 0.0001) compared with controls. Patients with urolithiasis had a higher Framingham Risk Scores [OR 8.36 (95% CI 3.81-18.65), p = 0.0001] and SCORE risk score [OR 3.02 (95% CI 1.30-7.02), p = 0.0006] compared with controls. The Framingham and SCORE risk score were significantly correlated with urinary calcium (p = 0.0001, r = 0.460, and p = 0.005, r = 0.223, respectively) and oxalate excretion (p = 0.0001, r = 0.516, p = 0.001, r = 0.290, respectively). In multiple linear regression analysis, urinary calcium and oxalate excretion, age, sex, total cholesterol, HDL-cholesterol, hsCRP and smoking were the independent predictors of 10-year cardiovascular disease risk and urinary calcium and oxalate excretion, age, sex, total cholesterol, fasting blood glucose for 10-year cardiovascular mortality. In conclusion, patients with calcium oxalate urolithiasis carry high risk of cardiovascular disease and mortality. All patients should be screened at the initial diagnosis of urolithiasis for the risk factors.

  20. Numerical quadrature methods for integrals of singular periodic functions and their application to singular and weakly singular integral equations

    1986-01-01

    High accuracy numerical quadrature methods for integrals of singular periodic functions are proposed. These methods are based on the appropriate Euler-Maclaurin expansions of trapezoidal rule approximations and their extrapolations. They are used to obtain accurate quadrature methods for the solution of singular and weakly singular Fredholm integral equations. Such periodic equations are used in the solution of planar elliptic boundary value problems, elasticity, potential theory, conformal mapping, boundary element methods, free surface flows, etc. The use of the quadrature methods is demonstrated with numerical examples.

    Background The current review revisits the article entitled: Active Ingredients of Behavioral Treatments for Alcohol Use Disorders (AUDs) published in Alcoholism: Clinical and Experimental Research. This work summarized proceedings from a 2004 Symposium of the same name that was held at the Annual Meeting of the Research Society on Alcoholism (RSA). A decade has passed, which provides occasion for an evaluation of progress. In 2014, an RSA symposium titled Active Treatment Ingredients and Client Mechanisms of Change in Behavioral Treatments for Alcohol Use Disorders: Progress 10 Years Later did just that. Overview The current review revisits state-of-the-art research on the three treatments examined 10 years ago: Cognitive Behavioral Therapy (CBT), Alcohol Behavior Couples Therapy (ABCT), and Twelve Step Facilitation (TSF). Because of its empirically-validated effectiveness and robust research agenda on the study of process-outcome, Motivational Interviewing (MI) has been selected as the fourth treatment modality to be discussed. For each of these four treatments, the reviewers provide a critical assessment of current theory and research with a special emphasis on key recommendations for the future. Conclusions Noteworthy progress has been made in identifying AITs and MOBCs in these four behavioral interventions for alcohol and other drug use disorders. Not only have we established some of the mechanisms through which these evidence-based treatments work, but we have also uncovered some of the limitations in our existing frameworks and methods. Further progress in this area will require a broader view with respect to conceptual frameworks, analytic methods, and measurement instrumentation. PMID:26344200

  3. An autocorrelation method to detect periodic gravitational waves from neutron stars in binary systems

    NASA Astrophysics Data System (ADS)

    Viceré, Andrea; Yvert, Michel

    2016-08-01

    Rotating, non-axisymmetric neutron stars are expected to emit continuous gravitational waves at a nearly stable frequency. Nowadays about 2500 pulsars have been detected, thanks to their beamed electromagnetic emission, and many more of these objects should exist, whose electromagnetic beam does not include Earth and cannot be detected. The gravitational emission is not beamed, and could be accessible to gravitational observatories, even though no detection as been claimed yet. About half of the pulsars predicted to possibly emit gravitational waves in the frequency range accessible to ground-based interferometers belongs to binary systems; this is an additional complication, because the frequencies of these pulsars are Doppler-shifted due to their orbital motion, and an optimal detection strategy would require a computing power far beyond the present capabilities. We present here an approach which allows searching all-sky for such sources, over a broad range of frequencies, orbital periods and binary system eccentricities, reaching sensitivities potentially good enough to provide candidates for more sophisticated hierarchical detection methods. We test this new technique using real data taken during the first science run of Virgo, and estimating the sensitivity to a set of simulated pulsar signals.

    Sitophilus zeamais Motschulsky is the most important insect pest of stored maize in tropical regions. The objective of this study was to determine the practicality of periodic physical disturbance on S. zeamais mortality and its adoption by smallholder farmers in developing countries. In this experiment, treatments and control were arranged in a randomized block design with three replications and three storage times in three regions of Tanzania. Region was used as the blocking variable. A total of 108 clean 20-L plastic containers were each loaded with 10 kg of fresh white dent corn and 0.50 kg of maize infested with S. zeamais. For the treatment, containers were disturbed twice a day, whereas for the controls the containers were not disturbed until the end of storage. The overall mortality rate (%) after 30, 60, and 90 days of storage were 88%, 96%, and 98%, respectively. A statistically significant difference (p < 0.05) was observed for the number of live S. zeamais between the control and experimental treatments. Additionally, the number of live S. zeamais in the treatment significantly decreased as storage time increased. This study shows the potential of a feasible, simple, affordable, and effective method of protecting maize grain for small-holder farmers in developing countries without using chemicals.

    The surface temperature measured by satellite can be the basis of evapotranspiration (ET) computation. The possibility of the daily sum of the regional ET using surface temperature was examined under Hungarian weather conditions. A simplified relationship, namely ET d-R nd= a+ b( Tc- Ta), which relates the daily ET to daily net radiation with one measurements of surface and air temperature was used for the calculation. Using NOAA AVHRR satellite data, no information about the surface inhomogeneity was obtained. The distribution of surface temperature was investigated by infrared thermometer scanning the surface from a board a hang-glider, ultra-light-aeroplane, and light aeroplane. Field observations trials were made during the vegetation period of 1992, 1993, 1994 and 1995. In eastern part of the country a homogeneous field ( 1 km×1 km) and a larger, and relatively homogeneous area was scanned, before noon and afternoon. In the western part of the country, a much larger area ( 45 km×45 km) was investigated. Cultivated area, forest and a large water surface were included in the investigated surface. The problems of calibration of hand-held infrared thermometer and the time shifting are discussed. Comparison of model output with data from field experiment has played a crucial role in model development and suggested an evaluation method.

    We report on a large Brazilian kindred with young-onset parkinsonism due to either a homozygous or heterozygous mutation in parkin. A total of 6 members were affected: 5 were homozygous and 1 heterozygous for a deletion in exon 4. Two other heterozygotes also had extrapyramidal signs. All affected subjects showed characteristic features of parkin disease with foot dystonia and an excellent response to levodopa complicated by motor fluctuations and dyskinesia within 3 years of therapy. Careful clinical follow-up over 10 years showed the phenotype was similar in all the homozygotes with asymmetrical limb bradykinesia and early walking difficulties. Some acceleration of disability was observed in some of the cases as they entered the third decade of illness, but dementia was absent.

    Internet pornography (IP) use has increased over the past 10 years. The effects of IP use are widespread and are both negative (e.g., relationship and interpersonal distress) and positive (e.g., increases in sexual knowledge and attitudes toward sex). Given the possible negative effects of IP use, understanding the definition of IP, the types of IP used, and reasons for IP use is important. The present study reviews the methodology and content of available literature regarding IP use in nondeviant adult populations. The study seeks to determine how the studies defined IP, utilized validated measures of pornography use, examined variables related to IP, and addressed form and function of IP use. Overall, studies were inconsistent in their definitions of IP, measurement, and their assessment of the form and function of IP use. Discussion regarding how methodological differences between studies may impact the results and the ability to generalize findings is provided, and suggestions for future studies are offered.

    Background: Iatrogenic complications such as accidental perforation of the root or the floor of the pulp chamber may occur. Case Report: Patient was referred for root canal retreatment of the mandibular left second molar with periapical lesion evidenced through radiographic examination. During post removal, iatrogenic perforation occurred at the mesial face of the distal root. After clinical localization of the perforation and bleeding control, MTA was applied. In a second appointment, the root canal filling was removed and the chemical-surgical retreatment of the canals was performed, followed by the obturation with gutta-percha and sealer. Patient returned after three days reporting no pain. After 6 months, 3, 7 and 10 years of follow-up. Conclusion: Absence of pain, normal periodontal probing and lack of radiolucent area at the region of perforation and the periapices were detected, which evidenced the successful repair of the tooth.

    10 years after the Chernobyl disaster gamma radioactivity from Cs-137 was determined in 53 breast milk samples from Tyrol, as well as 9 samples from Tibet and 2 from Nepal by means of a gamma-spectrometer with a germanium detector. In contrast to the values obtained within a few days, and again 1 year after the nuclear plant catastrophe, all samples from Tyrol showed gamma radioactivity levels (median 0.07 nCi/l; range 0.02-0.20 nCi/l) which were now below the limit laid down for baby food in Austria (0.3 nCi/l-11.1 Bq). The samples from Tibet and Nepal registered a slightly higher level of gamma radioactivity (median 0.16 nCi/l; range 0.16-0.41 nCi/l).

    A 10 year old girl with diarrhea, abdominal pain, weight loss and fever of one month and a half of evolution. Analytical and sonographic findings raised the possibility of inflammatory bowel disease. Endoscopy and histology showed findings consistent with Crohn's disease. Treatment was initiated with mesalazine and exclusive enteral nutrition. Later corticosteroid treatment, immunosuppressive drugs and ursodeoxycholic acid were added due to cholestasis and persistent hypergammaglobulinemia. Magnetic resonance cholangiography and liver biopsy confirmed the diagnosis of concomitant primary sclerosing cholangitis. The association between Crohn's disease and primary sclerosing cholangitis is rare, predominantly in males between 20 and 40 years old and it presents a great clinical variability. The confirmation of the diagnosis requires magnetic resonance cholangiography or endoscopic retrograde cholangiopancreatography. The prognosis is poor and there is no treatment to slow the progression of the disease.

    Forty-three patients with aortic rupture secondardy to blunt trauma have been treated at the University of Micigan within the past 10 years with an overall salvage rate of 70%. The diagnosis should be suspected in anyone who has sustained a high speed decelerating injury, if the chest roentgenogram shows media-stinal widening, whether or not there is hypertension of the upper extremities; systolic murmur, or external evidence of chest injury. Aortography should be employed to confirm the diagnosis and to determine the site or sites of rupture. Repair of the lesion should be undertaken as soon as possible and takes priority in most instances over associated injuries. Repair in almost all cases can be accomplished safely and quickly using a bypass shunt without the aid of extracorporeal circulation. Images Fig. 1. Fig. 2. PMID:962399

    Water needs of the population of Indian Wells Valley, Calif., must be met through further development of ground-water resources. Studies show that annual ground-water pumpage there has increased since 1945 and has exceeded mean annual recharge since 1966. Continued and increased stress on the aquifer system of the valley is expected because population in the valley is predicted to double by 1998 and triple by 2020, based on 1977 population figures. The U.S. Geological Survey proposes a 10-year program to develop a data base to aid in evaluation of future water-management alternatives. A study plan has been developed that describes present and potential problems and objectives of the program, and outlines work items to be undertaken in the study area. (USGS)

    Incontinentia pigmenti is a rare genodermatosis in which the skin involvement occurs in all patients. Additionally, other ectodermal tissues may be affected such as the central nervous system, eyes, hair, nails and teeth. The disease has an X-linked dominant inheritance pattern. But in our case, there was a mutation in the body cells due to incontinentia pigmenti. The dermatological findings occur in four successive phases. We report the case of a 10-year-old female presented cutaneous, dental and ophthalmic characteristic with 3 years follow-up. Dental anomalies such as hypodontia, peg-shaped anterior teeth, malformed primary and permanent teeth, and delayed eruption were seen in our patient. PMID:27602400

    The recognition that good prison health is important to general public health has led 28 countries in the European Region of the World Health Organization (WHO) to join a WHO network dedicated to improving health within prisons. Within the 10 years since that time, vital actions have been taken and important policy documents have been produced. A key factor in making progress is breaking down the isolation of prison health services and bringing them into closer collaboration with the country's public health services.However, barriers to progress remain. A continuing challenge is how best to move from policy recommendations to implementation, so that the network's fundamental aim of noticeable improvements in the health and care of prisoners is further achieved.

    The genetic and environmental etiology of high math performance (at or above the 85%tile) was examined in a population-based sample of 10-year-old twins (nMZ = 1,279, nDZ = 2,305). Math skills were assessed using a web-based battery of math performance tapping skills related to the UK National Math Curriculum. Probandwise concordance rates and liability threshold models indicated that genetic and shared environmental influences were significant, and that these estimates were generally similar to those obtained across the normal range of ability and did not vary significantly by gender. These results suggest that the genetic and environmental influences at the high end of ability are likely to be continuous with those that affect the entire range of math performance across all children irrespective of gender.

    More than 70 years have passed since the beginning of the Public Health Service syphilis study in Tuskegee, Alabama, and it has been over a decade since President Bill Clinton formally apologized for it and held a ceremony for the Tuskegee study participants. The official launching of the Tuskegee University National Center for Bioethics in Research and Health Care took place two years after President Clinton's apology. How might we fittingly discuss the Center's 10th Anniversary and the topic 'Commemorating 10 Years: Ethical Perspectives on Origin and Destiny'? Over a decade ago, a series of writers, many of them African Americans, wrote a text entitled 'African-American Perspectives on Biomedical Ethics'; their text was partly responsible for a prolonged reflection by others to produce a subsequent work, 'African American Bioethics: Culture, Race and Identity'. What is the relationship between the discipline of bioethics and African American culture? This and related questions are explored in this commentary.

    Effects of characteristics of science classrooms on the science achievement of students were examined in the context of a simple model. The model incorporated prior attributes of the students in terms of home background, sex, and verbal and quantitative ability. The model was estimated by means of partial least squares multivariate procedures using data for 10-year-old Queensland students from the Second International Science Study. The results demonstrated the dominant influence of home background and verbal/mathematical ability. Female students tended to have lower scores after allowing for the influence of the other variables in the model. Students who stated that there were more student initiated activities in their science lessons tended to have lower achievement.

    Myositis ossificans (MO) is a rare benign cause of heterotopic bone formation within soft tissue. It most commonly affects adolescents and young adults, typically in the limbs and following trauma. Very few cases have been reported in children. We report here a case of nontraumatic MO occurring in a 10-year-old girl with an uncommon location in the 5th right intercostal space; it was initially misdiagnosed and treated as osteosarcoma. Imaging findings including plain radiographs, CT, MRI, bone scintigraphy and PET-CT are described. This case highlights the central role played by imaging in diagnosis, thus avoiding biopsy that can erroneously suggest osteosarcoma as the diagnosis, as occurred in this case.

    Nitrogen containing bisphosphonate (N-BP) therapy is used extensively to treat osteoporosis and osteolytic bone lesions. Recently, a special form of osteonecrosis limited to the maxillofacial skeleton has been discovered especially within those patients who are receiving either long-term N-BP therapy alone and/or associated with invasive dental procedure. Bisphosphonates accumulate almost exclusively in maxillofacial skeleton owing to high bone turn over remodeling to maintain the mechanical competence. The pathogenesis and why it commonly appears in maxillofacial skeleton and the fixed treatment strategies remains unknown. The aim of this study was to improve the clinician understanding of N-BPs associated osteonecrosis of maxillofacial skeleton by reviewing the past 10 year literature. PMID:24932183

    Background Travel to school may offer a convenient way to increase physical activity levels in childhood. We examined the association between method of travel to school and physical activity levels in urban multi-ethnic children. Methods and Findings 2035 children (aged 9–10 years in 2006–7) provided data on their usual method of travel to school and wore an Actigraph-GT1M activity monitor during waking hours. Associations between method of travel and mean level of physical activity (counts per minute [CPM], steps, time spent in light, moderate or vigorous activity per day) were examined in models adjusted for confounding variables. 1393 children (69%) walked or cycled to school; 161 (8%) used public transport and 481 (24%) travelled by car. White European children were more likely to walk/cycle, black African Caribbeans to travel by public transport and South Asian children to travel by car. Children travelling by car spent less time in moderate to vigorous physical activity (−7 mins, 95%CI-9,-5), and had lower CPM (−32 CPM, 95%CI-44,-19) and steps per day (−813 steps, 95%CI,-1043,-582) than walkers/cyclists. Pupils travelling by public transport had similar activity levels to walkers/cyclists. Lower physical activity levels amongst car travellers' were especially marked at travelling times (school days between 8–9 am, 3–5 pm), but were also evident on weekdays at other times and at weekends; they did not differ by gender or ethnic group. Conclusion Active travel to school is associated with higher levels of objectively measured physical activity, particularly during periods of travel but also at other times. If children travelling by car were to achieve physical activity levels (steps) similar to children using active travel, they would increase their physical activity levels by 9%. However, the population increase would be a modest 2%, because of the low proportion of car travellers in this urban population. PMID:22319596

    In this study, we evaluated the association between prenatal and postnatal exposure to environmental tobacco smoke and the development of insulin resistance in 10 year old children. Fasting blood samples were collected from 470 children participating in two prospective birth cohorts. Of those 276 were selected population based and enriched with 194 children exceeding the 85th percentile of body mass index in this age group. Children already having diabetes type 1 or 2 at the age of 10 years were excluded. Fasting blood insulin and glucose levels and calculated HOMA index for insulin resistance assessment were analysed using generalised additive models. Potential confounders were adjusted for. Insulin resistance was increased by 24% in children frequently exposed to environmental tobacco smoke during childhood (MR(adj) = 1.24, p = 0.001), while glucose levels were not. Exclusion of prenatally exposed children did not attenuate the association (MR(adj) = 1.25, p = 0.006). After stratification, the effect sizes were identical within overweight children and the population based sample of children. Insulin resistance and fasting insulin levels were increasing with increasing numbers of cigarettes smoked in children's home. Maternal smoking during the third trimester of pregnancy increased children's insulin levels (MR(adj) = 1.19, p = 0.037), and even more so, if children were exclusively breastfed after birth (MR(adj) = 1.31, p = 0.016). Increased mean ratios were found for smoking of a third person in addition to maternal smoking. Positive dose-dependent associations and independent effects of postnatal exposure suggest involvement of environmental tobacco smoke in the risk for development of insulin resistance in children.

    We evaluate two 10-year-old mitigation bank wetlands in central Ohio, one created and one with restored and enhanced components, by analysis of vegetation characteristics and by comparison of the year-10 vegetation and macroinvertebrate communities with reference wetlands. To assess different measures of wetland development, we compare the prevalence of native hydrophytes with an index of floristic quality and we evaluate the predictability of these parameters in year 10, given 5 years of data. Results show that the mitigation wetlands in this study meet vegetation performance criteria of native hydrophyte establishment by year 5 and maintain these characteristics through year 10. Species richness and floristic quality, as well as vegetative similarity with reference wetlands, differ among mitigation wetlands in year 1 and also in their rate of change during the first 10 years. The prevalence of native hydrophytes is reasonably predictable by year 10, but 5 years of monitoring is not sufficient to predict future trends of floristic quality in either the created or restored wetland. By year 10, macroinvertebrate taxa richness does not statistically differ among these wetlands, but mitigation wetlands differ from reference sites by tolerance index and by trophic guild dominance. The created wetland herbivore biomass is significantly smaller than its reference, whereas detritivore biomass is significantly greater in the created wetland and smaller in the restored wetland as compared with respective reference wetlands. These analyses illustrate differences in measures of wetland performance and contrast the monitoring duration necessary for legal compliance with the duration required for development of more complex indicators of ecosystem integrity.

    We obtained data on the lengths, girths, and diameters of the fingers of children from 3 to 10 years of age. A total of 160 children (78 girls, 82 boys) were examined in a cross-sectional investigation. The length of each finger of the right hand of every child was measured, as were the girths of the proximal, middle, and distal phalanges, and of the proximal and distal interphalangeal joint. The average length of the thumb was 49 (35-65) mm. The index and ring fingers both averaged 69 (index, 50-88; ring, 42-96) mm in length, while the middle and little fingers averaged 72 (57-100) and 56 (40-74) mm, respectively. Average diameter, calculated from the girth measurement, was 16 (11-22) mm for the thumb, 15 mm for both the index (9-22) and middle (10-21) fingers, 14 (10-20) and 13 (8-19) mm for the ring and little fingers, respectively. The average length of each finger increased by 37% from 3 to 10 years of age, average girth by 24%, and diameter increased by 20%. We observed no differences in length, girth, and diameter between the sexes. The dimensions of children's fingers are relevant to injuries from automatic, power-operated window lifters of motor vehicles because risk of injury to a finger jammed between an ascending window and the seal entry depends upon the diameter of the finger. Additionally, short fingers of young children can be jammed over almost their entire length in the oblique design of a car window seal entry.

    This fall marks the 10th year in which we have run a research-project-based educational program for high school students and science teachers at the Lamont-Doherty Earth Observatory. This summer's cohort included 31 teenagers, 7 science teachers, and 16 college students, most of whom are returning to the program to help run the research projects. Nearly all of our students attend non-competitive-entry public schools in NYC or the neighborhoods around the Observatory. Over 80% are from under-served minority populations. Most receive Title I/III assistance. About 60% are young women. During the past 10 years, nearly all of our participants have gone on to 4-year colleges. About half are declaring science and engineering majors. Our students receive scholarship support at rates several times higher than their graduating peers, including 5 Gates Millennium scholars over the past 5 years. Our science is centered on studies of a nearby tidal wetland, where we have expanded from fish collections in year one to include everything from sediment core analysis to soil chemistry to nutrient cycles to the local food web. In this presentation we will look back over 10 years of experience and focus on what lessons can be learned about (1) how to engage teams of young investigators in authentic scientific research; (2) what cultural/organizational structures encourage them to make use of place- and project-based learning and (3) what the participants themselves report as the most useful aspects of our programming. The presentation will include video clips from the students' field experiences and from reflective interviews with "graduates".

    For 20 years Active Healthy Kids Canada (AHKC) has worked to inspire the country to engage all children and youth in physical activity (PA). The primary vehicle to achieve this is the AHKC Report Card on Physical Activity for Children and Youth, which has been released annually since 2005. Using 10 years of experience with this knowledge translation and synthesis mechanism, this paper aggregates and consolidates diverse evidence demonstrating the impact of the Report Card and related knowledge translation activities. Over the years many evaluations, consultations, assessments, and surveys have helped inform changes in the Report Card to improve its impact. Guided by a logic model, the various assessments have traversed areas related to distribution and reach, meeting stakeholder needs, use of the Report Card, its influence on policy, and advancing the mission of AHKC. In the past 10 years, the Report Card has achieved > 1 billion media impressions, distributed > 120,000 printed copies and > 200,000 electronic copies, and benefited from a collective ad value > $10 million. The Report Card has been replicated in 14 countries, 2 provinces, 1 state and 1 city. AHKC has received consistent positive feedback from stakeholders and end-users, who reported that the Report Card has been used for public awareness/education campaigns and advocacy strategies, to strengthen partnerships, to inform research and program design, and to advance and adjust policies and strategies. Collectively, the evidence suggests that the Report Card has been successful at powering the movement to get kids moving, and in achieving demonstrable success on immediate and intermediate outcomes, although the long-term goal of improving the PA of Canadian children and youth remains to be realized.

    OBJECTIVE The aim of this study was to investigate the treatment outcomes and social engagement of patients who had undergone pediatric epilepsy surgery more than 10 years earlier. METHODS Between 1983 and 2005, 110 patients younger than 16 years underwent epilepsy surgery at the National Epilepsy Center, Shizuoka Institute of Epilepsy and Neurological Disorders. The authors sent a questionnaire to 103 patients who had undergone follow-up for more than 10 years after surgery; 85 patients (82.5%) responded. The survey contained 4 categories: seizure outcome, use of antiepileptic drugs, social participation, and general satisfaction with the surgical treatment (resection of the epileptic focus, including 4 hemispherectomies). The mean patient age at the time of surgery was 9.8 ± 4.2 (SD) years, and the mean duration of postoperative follow-up was 15.4 ± 5.0 years. Of the 85 patients, 79 (92.9%) presented with a lesional pathology, such as medial temporal sclerosis, developmental/neoplastic lesions, focal cortical dysplasia, and gliosis in a single lobe. RESULTS For 65 of the 85 responders (76.5%), the outcome was recorded as Engel Class I (including 15 [93.8%] of 16 patients with medial temporal sclerosis, 20 [80.0%] of 25 with developmental/neoplastic lesions, and 27 [73.0%] of 37 with focal cortical dysplasia). Of these, 29 (44.6%) were not taking antiepileptic drugs at the time of our survey, 29 (44.6%) held full-time jobs, and 33 of 59 patients (55.9%) eligible to drive had a driver's license. Among 73 patients who reported their degree of satisfaction, 58 (79.5%) were very satisfied with the treatment outcome. CONCLUSIONS The seizure outcome in patients who underwent resective surgery in childhood and underwent followup for more than 10 years was good. Of 85 respondents, 65 (76.5%) were classified in Engel Class I. The degree of social engagement was relatively high, and the satisfaction level with the treatment outcome was also high.

  10. Rosetta begins its 10-year journey to the origins of the Solar System

    NASA Astrophysics Data System (ADS)

    2004-03-01

    Rosetta’s mission began at 08h17 CET (07h17 GMT) on 2 March when a European Ariane 5 launch vehicle liftered off from the Guiana Space Centre, Europe’s spaceport in Kourou, French Guiana. The launcher successfully placed its upper stage and payload into an eccentric coast orbit (200 x 4000 km). About two hours later, at 10h14 CET (09h14 GMT) the upper stage ignited its own engine to reach an escape velocity in order to leave the Earth’s gravity field and enter heliocentric orbit. The Rosetta probe was released about 18 minutes later. “After the recent success of Mars Express, Europe is now heading to deep space with another fantastic mission. We will have to be patient, as the rendezvous with the comet will not take place until ten years from now, but I think it’s worth the wait” said ESA’s Director General Jean-Jacques Dordain witnessing the launch from Kourou. ESA’s Operations Centre (ESOC) in Darmstadt, Germany, has established contact with the probe as it flies away from Earth at a relative speed of about 3.4 km/s. ESOC will be in charge of Rosetta operations and orbit determination throughout the mission. During the next eight months, the spacecraft’s onboard systems will be checked and its science payload will be commissioned. A 10-year odyssey Rosetta will be reactivated for planetary flybys, which will be used to modify its trajectory through gravity assist manoeuvres. During the trip, the probe could also observe one or more asteroids, observation of asteroids being one of the mission's secondary objectives. The first planetary encounter will be in March 2005, as Rosetta flies by the Earth for the first time. The gravity assist will boost Rosetta into an orbit that will take it to Mars two years later. During its close encounter with Mars in February 2007, Rosetta will approach to a distance of about 200 km and conduct science observations. This Martian flyby will be followed by another Earth flyby in November the same year. Both

    Periodicity is an important property of speech signals. It is the basis of the signal's fundamental frequency and the pitch of voice, which is crucial to speech communication. This paper presents a novel framework of periodicity enhancement for noisy speech. The enhancement is applied to the linear prediction residual of speech. The residual signal goes through a constant-pitch time warping process and two sequential lapped-frequency transforms, by which the periodic component is concentrated in certain transform coefficients. By emphasizing the respective transform coefficients, periodicity enhancement of noisy residual signal is achieved. The enhanced residual signal and estimated linear prediction filter parameters are used to synthesize the output speech. An adaptive algorithm is proposed for adjusting the weights for the periodic and aperiodic components. Effectiveness of the proposed approach is demonstrated via experimental evaluation. It is observed that harmonic structure of the original speech could be properly restored to improve the perceptual quality of enhanced speech.

    The aim of the present study was a light and scanning electron microscopy (SEM) evaluation of the peri-implant tissues around sandblasted, acid-etched implants, retrieved from man, after a loading period of 5 and 10 years, respectively. Two implants (Leone Implant System) had been retrieved for a fracture of the prosthetic superstructure respectively after 5 and 10 years of loading. Both implants were stable before retrieval and had been retrieved using a 5-mm trephine bur. One implant was treated to obtain thin ground sections, while the other underwent evaluation under SEM. Compact, mature lamellar bone was present over most of the implant perimeter in close contact with the implant surface and with many remodeling areas. Under SEM, small concavities, completely filled by mineralized bone, were present on the implant surface. The present histologic results showed that these implants were well integrated over the long term, and the peri-implant bone was undergoing continuous remodeling at the interface.

    PurposeTo evaluate the ability of baseline clinical, morphological, and functional factors to predict the conversion to primary open-angle glaucoma (POAG) in ocular hypertensive (OHT) patients.MethodsThis single-center prospective longitudinal observational study included 116 eyes of 116 OHT patients followed for a 10-year period. All patients had intraocular pressure (IOP) ≥24 mm Hg in one eye and >21 mm Hg in the other eye, normal visual fields (VFs) and normal optic disc (OD) appearance in both eyes at baseline. All OHT patients were untreated at baseline with subsequent treatment upon need according to clinical judgement. Only one eye per subject was randomly selected. Patient age, gender, IOP, central corneal thickness (CCT), and ibopamine test results were collected at baseline. All patients underwent standard automated perimetry, short-wavelength automated perimetry (SWAP), frequency-doubling technology, confocal scanning laser ophthalmoscopy (CSLO), and scanning laser polarimetry (SLP) at baseline and every 6 months thereafter. Main outcome measure was the conversion to POAG, defined as the development of reproducible VF and/or OD abnormalities attributable to glaucoma. Cox proportional hazards models were used to identify the baseline factors predictive of POAG conversion.ResultsDuring the 10-year follow-up, 25% of eyes converted to POAG. In multivariate Cox models, baseline factors that were significant predictors of POAG development included: older age (hazard ratio (HR) 1.0, 99% confidence intervals (CIs) 1.0-1.2, per 1 year older); SWAP Glaucoma Hemifield test 'outside normal limits' (HR 4.3, 99% CIs 1.2-17.9); greater SLP 'Inter-eye Symmetry' (HR 1.1, 99% CIs 0.4-3.0, per 1 unit lower); lower CSLO Rim Volume (HR 1.1, 99% CIs 0.3-3.2, per 0.1 mm(3) lower); and greater CSLO cup-to-disc ratio (HR 6.0, 99% CIs 3.6-16.8, per 0.1 unit greater).ConclusionsThe baseline parameters that proved to be useful in assessing the likelihood of an OHT

    In the paper, the Long period fiber gratings (LPFG) were fabricated in a single-mode fiber using a high frequency CO2 laser system with the point-to-point technique. The experimental setup consists of a CO2 laser controlling system, a focusing system located at a motorized linear stage, a fiber alignment stage, and an optical spectrum analyzer to monitor the transmission spectrum of the LPFG. The period of the LPFG is precisely inscribed by periodically turning on/off the laser shutter while the motorized linear stage is driven to move at a constant speed. The efficiency of fiber writing process is improved.

    Background A thymectomy is considered effective for patients with myasthenia gravis (MG). Although a few studies have described the role of a thymectomy in the treatment of MG in Asians countries, there are no published data on the application of this surgical approach for MG in Malaysia. We aimed to describe the clinical outcomes of MG patients who underwent a thymectomy and the factors affecting these outcomes. Methods This was a retrospective study involving 16 patients with MG who underwent a thymectomy at the Hospital Universiti Sains Malaysia (HUSM) from January 2002 until December 2012, with a follow-up period ranging from 3–120 months. Results The study consisted of 16 patients aged 22–78 years, 10 of whom were males. The overall remission/improvement rate was 87.5%, and the rate of clinical outcomes classified as unchanged/worsened was 12.5%. Thymomamatous or non-thymomamatous MG, histology features, Osserman stage and the duration of follow-up were not significant prognostic factors. Post-operative mortality was 6.2% (1 of 16 patients died of septic shock). Conclusion A thymectomy seems to be an effective treatment for MG, with low surgical morbidity. Patients with a lower Osserman stage and those with/without thymomas had favourable outcomes. PMID:27660548

    Objectives: To determine the outcomes of coblation assisted transnasal endoscopic resection of nasopharyngeal cyst. Method: Retrospective chart review outcomes in 12 patients who underwent endoscopic resect cysts of the nasopharynx at our department between 2001 and 2010. Twelve patient, aged 28 to 71 years, with cysts of the nasopharynx. The outcome variables of complications and the rate of recurrence were analyzed, respectively. Results: In 12 cases, retention cysts in 2 cases, branchial cyst in 1 case, adenoid middle fossa cyst infection in 6 cases, Tornwaldt’s cyst in 3 cases. The use of the coblation device was associated with a significant decrease in blood loss. There were no postoperative complications, and the overall follow-up period was 2-7 years and shows no signs of recurrence. Conclusions: We describe transnasal endoscopic procedures to resect cysts of the nasopharynx. We found that radiofrequency coblation is a useful and safe tool associated with minimal blood loss in the resection of these cysts. In our experience, it has been a highly successful, safe, and effective procedure. PMID:26131108

    This study investigated the relation between major depressive disorder (MDD) and smoking relapse in the U.S. over a 10-year period. Data were drawn from the Midlife Development in the United States (MIDUS) Survey Waves I & II. Logistic regression analyses were used to explore the associations between past-year MDD in 1994, past-year MDD in 2005 and persistent depression (1994 and 2005) and risk of smoking relapse in 2005 among former smokers, adjusting for demographics, anxiety disorders, and substance use problems and smoking characteristics. Among former smokers, MDD in 1994, compared to without MDD in 1994, was associated with significantly increased odds of smoking relapse by 2005. Current MDD in 2005 was associated with an even stronger risk of relapse in 2005 and persistent depression even more strongly predicted relapse by 2005. These associations remained significant and were not substantially attenuated by the covariates. In conclusion, MDD appears to confer long-term vulnerability to smoking relapse among adults in the general population. These results suggest interventions for smoking cessation should include screening and treatment for MDD if programs are to be optimally effective at achieving initial quit success as well as enduring abstinence.

    The present study was carried out to understand the adaptive strategies developed by Stenotrophomonas maltophilia for chronic colonization of the cystic fibrosis (CF) lung. For this purpose, 13 temporally isolated strains from a single CF patient chronically infected over a 10-year period were systematically characterized for growth rate, biofilm formation, motility, mutation frequencies, antibiotic resistance, and pathogenicity. Pulsed-field gel electrophoresis (PFGE) showed over time the presence of two distinct groups, each consisting of two different pulsotypes. The pattern of evolution followed by S. maltophilia was dependent on pulsotype considered, with strains belonging to pulsotype 1.1 resulting to be the most adapted, being significantly changed in all traits considered. Generally, S. maltophilia adaptation to CF lung leads to increased growth rate and antibiotic resistance, whereas both in vivo and in vitro pathogenicity as well as biofilm formation were decreased. Overall, our results show for the first time that S. maltophilia can successfully adapt to a highly stressful environment such as CF lung by paying a “biological cost,” as suggested by the presence of relevant genotypic and phenotypic heterogeneity within bacterial population. S. maltophilia populations are, therefore, significantly complex and dynamic being able to fluctuate rapidly under changing selective pressures. PMID:27746770

    147 patients who underwent urinary intestinal diversion from 2004 to 2014 were selected for the retrospective study. The authors carried out a comparative analysis of rates of complications that arise from the direct ureterointestinal anastomosis. The mean age of patients was 54.2 ± 3.0 (36-69) years. 60 (40.81%) patients of group 1 underwent Nesbit's direct ureterointestinal anastomosis, while in 87 (59.19%) patients of group 2 Wallace-1 and Wallace-2 anastomoses were performed. Average follow-up was 5.6 (2-10) years. Strictures of ureterointestinal anastomosis were detected in 2 (3.38%) patients of group 1 and in 1 (1.14%) patient of group 2. In all cases re-anastomosis was performed. The maximum postoperative concentration of serum creatinine in both groups was 231 mmol/l. According to radioisotope kidney scan, no differences in accumulative and excretory renal functions between two groups of patients were recorded. No kidney stone formation in both groups of patients during the follow-up period was observed. No ureteral reflux above grade 3 was noted. The clinical manifestation of reflux pyelonephritis was observed in 3.5% of the patients. Acute pyelonephritis was cured by antibacterial therapy.
