Abstract
This study examined associations between school sector (Government, Catholic or Independent) and depressive symptomology over the secondary school years. Six waves of data collected annually from a representative Australian sample were examined. Multilevel piecewise linear and logistic regression controlling for a variety of demographic variables and protective factors was undertaken. In all sectors, depressive symptomology decreased between 10 and 13 years of age, but significantly increased for girls at age 13. Adolescents in Catholic schools reported significantly fewer symptoms of depression compared to those in Government and Independent schools. Adolescents in Catholic schools were less likely to report clinical levels of depressed mood compared to adolescents in Government schools.

Abstract
It is widely accepted that Newcastle disease is endemic in most African countries, but little attention has been afforded to establishing the sources and frequency of the introductions of exotic strains. Newcastle disease outbreaks have a high cost in Africa, particularly on rural livelihoods. Genotype VIIh emerged in South-East Asia and has since caused serious outbreaks in poultry in Malaysia, Indonesia, southern China, Vietnam and Cambodia. Genotype VIIh reached the African continent in 2011, with the first outbreaks reported in Mozambique. Here, we used a combination of phylogenetic evidence, molecular dating and epidemiological reports to trace the origins and spread of subgenotype VIIh Newcastle disease in southern Africa. We determined that the infection spread northwards through Mozambique, and then into the poultry of the north-eastern provinces of Zimbabwe. From Mozambique, it also reached neighbouring Malawi and Zambia. In Zimbabwe, the disease spread southward towards South Africa and Botswana, causing outbreaks in backyard chickens in early-to-mid 2013. In August 2013, the disease entered South Africa's large commercial industry, and the entire country was infected within a year, likely through fomites and the movements of cull chickens. Illegal poultry trading or infected waste from ships and not wild migratory birds was the likely source of the introduction to Mozambique in 2011.

Abstract
BACKGROUND The Global Rating Scale, defined by the Joint Advisory Group for Gastrointestinal Endoscopy, requires monitoring of endoscopic performance indicators. There are known variations in colonoscopic performance, and investigation of factors causing this is needed. This study aimed to analyse the impact of endoscopist specialty and procedural volume on the quality of colonoscopy. METHODS Data collected prospectively from a UK hospital endoscopy service between June 2007 and January 2010 were analysed. The main endpoint was the adenoma detection rate (ADR). Secondary endpoints were polyp detection rate (PDR), reported caecal intubation rate (CIR) and reported complications. Multivariable binary regression models were built to adjust for confounding patient-level and endoscopist-level variation. RESULTS A total of 10,026 colonoscopies were included, with an overall ADR of 19.2 per cent, a CIR of 90.2 per cent and a perforation rate of 0.06 per cent. In univariable analyses, surgeons had a higher ADR and higher PDR, but lower CIR, compared with physicians. Surgeons had a significantly different case mix in terms of age, sex and indication for colonoscopy. After adjusting for this case mix in multivariable analysis, specialty was no longer a significant predictor of ADR; however, surgeons retained their higher PDR and physicians their higher CIR. Endoscopists accredited for screening and those performing more than 100 colonoscopies per year had a higher ADR. CONCLUSION Adjusting for case mix, physicians and surgeons performed equally well in terms of ADR. Accreditation and a higher annual number of colonoscopies were more important factors in achieving quality standards.

Abstract
A serological survey of leptospirosis in cattle originating from rural communities of the province of KwaZulu-Natal (KZN) in South Africa was carried out between March 2001 and December 2003. The survey was designed as a 2-stage survey, using the local diptank as the primary sampling point. In total, 2021 animals from 379 diptanks in 33 magisterial districts were sampled and tested with the microscopic agglutination test (MAT). The apparent prevalence at district level was adjusted for clustering and diagnostic test sensitivity and specificity and displayed in maps. The prevalence of leptospirosis in cattle originating from communal grazing areas of KZN was found to be 19.4% with a 95% confidence interval of 14.8-24.1%. At district level the prevalence of leptospirosis varied from 0 to 63% of cattle. Bovine leptospirosis was found to occur in communal grazing areas throughout the province with the exception of 2 districts. The southeastern regions showed a higher prevalence than other areas of the province; while in some of the northern and western districts a lower prevalence was noted. Several serovars were detected by the MAT and although Leptospira interrogans serovar pomona occurred most frequently, serovars tarrasovi, bratislava, hardjo, canicola and icterohaemorrhagica were also frequently identified. The findings of the survey are discussed.

Abstract
A questionnaire survey of 315 cattle owners from the rural districts of KwaZulu-Natal was carried out. The aim of the survey was to improve our understanding of local farmers' perceptions and practices of animal disease prevention and control and to establish the extent of their relationship with veterinary services. The survey showed that many owners practice preventive measures such as deworming, tick control and vaccination. Traditional medicines were in use by over half the respondents (58.9 %). Diseases are regarded as an important management problem (56.1 %); ticks, worms and diarrhoea dominated the mentioned health problems in cattle. Veterinary services still play an important role and are a frequent source of advice to owners. The findings of the survey and their context are discussed.

Abstract
A serological survey of Brucella abortus in cattle originating from communal grazing areas of Kwa Zulu Natal was carried out between March 2001 and December 2003. The survey was designed as a 2-stage survey, considering the diptank as the primary sampling unit. In total 46 025 animals from 446 diptanks of 33 magisterial districts were sampled and tested using the Rose Bengal test and Complement Fixation Test. The apparent prevalence at district level was adjusted for clustering, diagnostic test sensitivity and specificity, and mapped using ArcView version 3.3. The prevalence of brucellosis in communal grazing areas of Kwa-Zulu Natal was found to be 1.45 % (0.84-2.21 %) and varied from 0 to 15.6% between magisterial districts. In 19 of the 33 magisterial districts no serological reactors were observed. A large variation in prevalence was found within diptank areas. Brucellosis was found to be most prevalent in the northeastern area of the province. The findings of the survey are discussed.

Abstract
Stroke is the third leading cause of death and a leading cause of adult disability in the United States. Both within and outside of the Veterans Health Administration (VHA), the lack of a systematic approach to stroke prevention and treatment may have contributed to reduced rates of compliance with recommended practices and increased rates of stroke. Gaps in the knowledge base inhibit a systematic approach to high-quality care within the veteran population. Initial recommendations for closing those gaps are proposed. In some cases (eg, systematic anticoagulation management), the VHA is perceived as a leader in applied research; therefore, a systematic national policy for implementing these clinics may significantly reduce stroke rates. In other areas (eg, carotid endarterectomy), databases exist that would help advance quality and outcomes, but short-term studies are necessary to establish their utility. To promote strategic improvement in prevention, treatment, and rehabilitation for veterans who may be at risk or have had a stroke, specific objectives are proposed to (1) identify best practices for the effective delivery of long-term anticoagulation and enhance veterans' access to these services, (2) develop risk-adjusted models for the surgical preventive procedure carotid endarterectomy to understand facility variation in outcomes so practices can be improved, (3) define a systematic acute stroke management system so that high-quality stroke-related care can be generalizable to a variety of VHA settings, and (4) assess the impact of poststroke rehabilitation on risk adjustment and the location of outcomes so as to facilitate the implementation of best rehabilitation practices.

Abstract
OBJECTIVES Approximately 1,100 communities in the United States have combined sewer and stormwater systems whose capacity may be exceeded during moderate or heavy rainfall. Outflows may occur that can deposit water with varying concentrations of the components of sewage onto public areas, where contact with residents or workers is possible, potentially resulting in a range of adverse health effects. This study proposes and applies three analytic methods to evaluate the impact of such outflows on public health. METHODS The work attendance records of 449 U.S Postal Service letter carriers in Sacramento, CA, were reviewed to determine the frequency of sick leave use (as a surrogate measure of illness) in relationship to rainfall and potential exposure to sewage-contaminated outflows in two distinct groups of letter carriers from October 1, 1992, through April 30, 1993. Rainfall was a surrogate measure of outflows from the combined sewer and stormwater system because no information existed about the extent of exposure of these (or any other) workers. One group of letter carriers delivered mail exclusively within an area served by the combined sewer and stormwater collection system; the second group delivered mail exclusively outside this area where sewage and stormwater collection are separated. The first approach to the assessment of the data was a description of the temporal relationship between rainfall patterns and absentee rates in the two groups of workers. The second approach used logistic regression modelling with varying lags between rainfall and sick leave usage. The third approach used Poisson regression analysis of the entire study period to examine the differential impact of rainfall on the two groups. RESULTS The descriptive analyses detected no relationship between rainfall and sick leave use. The logistic regression analyses detected evidence (as measured by the interaction coefficient in logistic models) of an increased use of sick leave by the letter carriers within the Combined System area at lag periods of one, four, and five days after rainfall. These estimates were not, however, statistically significant (p > 0.05). The Poisson regression analysis showed no evidence of a differential impact of rainfall on the two groups (incidence rate ratio = 1.19 in both groups for periods of rain versus no rain). CONCLUSIONS These three methods can be used to investigate the public health impact of combined system outflows. Ideally, however, these approaches would be applied to prospectively collected surveillance data that would rely upon direct measurements of exposure and illness, rather than surrogate variables.

Abstract
GPs are not always informed that their patient suffered an adverse drug reaction (ADR) while in hospital. We have conducted a postal questionnaire survey of 270 GPs in order to elicit their views regarding provision of information from secondary care regarding ADRs. Of the 141 (52.2%) GPs that replied, 127 (90.1%) saw patients that had experienced an ADR in hospital. Of these GPs, 113 (89%) stated that they encountered instances where no record of the ADR existed in patients' discharge documentation. Where written information was absent, GPs are reliant on information given to them by patients. Of those responding, none were 'very confident' of this information, while 92 (78.6%) were 'uncertain' or 'very uncertain' of this information. A sample notification form was developed. GPs were generally satisfied with its content and 110 (82.7%) thought that patients should receive a copy. Almost all GPs (135 (97.8%)) felt that it would be appropriate to provide patients with ADR warning cards. Ensuring that patients and their carers are aware of drugs to which they may be allergic or intolerant through verbal and written methods should minimize the unnecessary risks of inadvertent re-exposure.

Abstract
OBJECTIVE To determine whether medication use patterns in community-dwelling elderly people vary with level of cognitive function-dementia, cognitive impairment (but not dementia) and intact cognition. DESIGN Cross-sectional survey. SETTING A five-county area of central North Carolina, USA. PARTICIPANTS 520 members of the Duke Established Populations for Epidemiologic Studies of the Elderly. MEASUREMENTS Medication use in the previous 2 weeks was ascertained during a interview in the patient's home and was coded as to prescription and therapeutic class status. Cognitive status, the primary independent variable, was divided into: (i) dementia (n=100); (ii) cognitive impairment but not dementia (n=117); and (iii) cognitively intact (n=303). The dependent variables were any prescription or over-the-counter (OTC) medication use (vs non-use); number of prescription or OTC medications used; and prescription and OTC use combined within major therapeutic classes. Multivariate analyses controlled for socio-demographic characteristics, health status, functional status and access to health care. RESULTS The use of any prescription medication was similar in the three groups. The demented were significantly less likely than cognitively impaired people to use any OTC medications (OR=0.65, 95% CI=0.45, 0.93), cardiovascular medications (OR=0.70, 95% CI=0.49, 0.99) and analgesics (OR=0.54, 95% CI=0.39, 0.75). As a combined group, those who were demented and cognitively impaired were less likely than the cognitively intact group to use any OTC medications (OR=0.78, 95% CI 0.65, 0.92). Compared with the cognitively impaired subjects, the demented group took fewer prescription medications (beta coefficient=-0.31, 95% CI=-0.59, -0.03) and similar numbers of OTC medications. Compared with those who were cognitively intact, the combined group of demented and cognitively impaired subjects took fewer OTC medications (beta coefficient=-0.14, 95% CI=-0.23, -0.05) and similar numbers of prescription medications. CONCLUSION Increasing level of cognitive dysfunction is associated with decreased use of OTC, cardiovascular and analgesic medications and the use of fewer prescription medications. These results suggest important differences in medication use patterns among community-dwelling elderly people who vary in cognitive status.

Abstract
Substantial progress towards the global eradication of poliomyelitis by the year 2000 has been achieved since May 1988 when WHO Member States adopted this goal at the Forty-first World Health Assembly. Virtually all polio-endemic countries have begun to implement the WHO-recommended strategies to eradicate polio and it is expected that, by the end of 1997, all endemic countries in the world will have conducted full National Immunization Days (NID), providing supplemental oral polio vaccine (OPV) to nearly two-thirds of all children < 5 years. In contrast, although globally acute flaccid paralysis (AFP) surveillance was being conducted in 126 (86%) of 146 countries where polio is or recently was endemic, surveillance remains incomplete and untimely. A global network of polio laboratories, capable of detecting wild poliovirus when and where it occurs, has been developed. Furthermore, in countries where polio virus circulation has been limited to focal areas, and surveillance is adequate, mopping-up campaigns are being conducted to eliminate the final chains of transmission. The process for certification of polio eradication has been established in each WHO region as well as at the global level. The impact of the eradication initiative is evident, with an 88% decrease in the number of reported cases globally since 1988. In order to achieve the goal of eradication, the rapid development of complete and timely AFP surveillance and the continuation of effective NIDs constitute an urgent priority. This is of particular relevance in the remaining polio-endemic countries, especially in those that are affected by war or politically isolated and are important remaining reservoirs from where wild poliovirus continues to spread into bordering or even distant polio-free countries. External support will continue to be required by those countries and regions where the incidence of polio has reached low levels to ensure that final chains of poliovirus transmission are interrupted and to permit the eventual certification of eradication. The year 2000 objective for achieving poliomyelitis eradication remains a feasible target.

Abstract
Two experiments were performed to assess viral inactivation during the crosslinking and heat treatment steps of the DCLHb manufacturing process. Stroma free hemoglobin (SFHb) collected from a large scale manufacturing lot was tested in a 1:680 scaled down system in which the key parameters used in the manufacturing process were replicated. In the first study Porcine Parvovirus (PPV), a non-enveloped virus, was used to assess inactivation, while in the second study Bovine Viral Diarrhea Virus (BVDV), an enveloped virus, was utilized. In both experiments, the SFHb solution was deoxygenated and an aliquot of virus suspension was added. To initiate the crosslinking reaction, a solution of bis (3,5-dibromosalicyl) fumarate (DBBF) in HEPES buffer was added to the test solution. In both experiments the reaction times and the degree of crosslinking were normal. After crosslinking, the reaction mixtures were heated to 74 +/- 1 degrees C over 30 minutes, held at 74 +/- 1 degrees C for 90 minutes, and cooled to less than 10 degrees C over 30 minutes. In each experiment the degree of crosslinking of final product was 100% and yield of hemoglobin recovery was normal. Samples were removed prior to crosslinking, after crosslinking and before, during and after heat treatment for determination of virus titer and evaluation of key process parameters. The results from these experiments were consistent with those obtained from the full scale manufacturing process for the deoxygenation, crosslinking and the heat treatment step during the production of DCLHb. The results of virus assays showed that crosslinking has no effect on viruses and their subsequent inactivation by heat treatment.

Abstract
OBJECTIVE To examine specifically the influence of estimated perioperative mortality and stroke rate on the assessment of appropriateness of carotid endarterectomy. DATA SOURCES/STUDY SETTING An expert panel convened to rate the appropriateness of a variety of potential indications for carotid endarterectomy based on various rates of perioperative complications. We then applied these ratings to the charts of 1,160 randomly selected patients who had carotid endarterectomy in one of the 12 participating academic medical centers. STUDY DESIGN An expert panel evaluated indications for carotid endarterectomy using the modified Delphi approach. Charts of patients who received surgery were abstracted, and clinical indications for the procedure as well as perioperative complications were recorded. To examine the impact of surgical risk assessment on the rates of appropriateness, three different definitions of risk strata for combined perioperative death or stroke were used: Definition A, low risk < 3 percent; Definition B, low risk < 5 percent; and Definition C, low risk < 7 percent. PRINCIPAL FINDINGS Overall hospital-specific mortality ranged from 0 percent to 4.0 percent and major complications, defined as death, stroke, intracranial hemorrhage, or myocardial infarction, varied from 2.0 percent to 11.1 percent. Most patients (72 percent) had surgery for transient ischemic attack or stroke; 24 percent of patients were asymptomatic. Most patients (82 percent) had surgery on the side of a high-grade stenosis (70-99 percent). When the thresholds for operative risk were placed at the values defined by the expert panel (Definition A), only 33.5 percent of 1,160 procedures were classified as "appropriate." When the definition of low risk was shifted upward, the proportion of cases categorized as appropriate increased to 58 percent and 81.5 percent for Definitions B and C, respectively. CONCLUSIONS Despite the high proportion of procedures performed for symptomatic patients with a high degree of ipsilateral extracranial carotid artery stenosis and generally low rates of surgical complications at the participating institutions, the overall rate of "appropriateness" using a perioperative complication rate of < 3 percent was low. However, the rate of "appropriateness" was extremely sensitive to judgments about a single clinical feature, surgical risk. These data show that before applying such "appropriateness" ratings, it is crucial to perform sensitivity analyses in order to assess the stability of the results. Results that are robust to moderate in variation in surgical risk provide a much sounder basis for policy making than those that are not.

Abstract
OBJECTIVE To determine the relationship of surgical repair of acute hip fracture within 2 days of hospital admission, followed by more than 5 sessions per week of physical and occupational therapy (PT/OT), to outcomes after acute hip fracture. DESIGN Comparison of hip fracture outcomes via secondary analysis of data obtained by retrospective medical record review according to timing of surgical repair and frequency of PT/OT, adjusted for patient, medical care, and hospital characteristics. SAMPLE The study included the medical records of 1880 elderly Medicare recipients admitted from the community to 284 acute care hospitals in 5 states during 1981 and 1982 or 1985 and 1986 with a primary diagnosis of acute hip fracture who underwent surgical repair and received PT/OT. INTERVENTIONS None. MAIN OUTCOME MEASURES The postoperative day when ambulation first occurred, the length of hospital stay, and return to the community. RESULTS Earlier surgical repair was associated with a shorter length of hospital stay (5 fewer days, P < .001) without a statistically significant increase in medical complications. High frequency PT/OT was associated with earlier ambulation (odds ratio [OR], 1.76; 95% confidence limits [CL], 1.50, 2.07). Patients who ambulated earlier [corrected] had shorter lengths of stay (6.5 fewer days, P < .001), were more likely to return to the community (OR, 1.45; 95% CL, 1.16, 1.81), and had better 6-month survival (OR, 2.8; 95% CL, 2.06, 3.88), and patients younger than 85 years had fewer in-hospital complications (11% vs 4%, P < .001). CONCLUSION Surgical repair within the first 2 days of hospitalization and more than 5 PT/OT sessions per week were associated with better health outcomes in a nationally representative sample of elderly patients with hip fracture.

Abstract
Induction of the d-amino acid oxidase (EC. 1.4.3.3) from the yeast Trigonopsis variabilis was investigated by using a minimal medium containing glucose as the carbon and energy source, (NH(inf4))(inf2)SO(inf4) as the nitrogen source, and various d- and dl-amino acid derivatives as inducers. The best new inducers found were N-carbamoyl-d-alanine, N-acetyl-d-tryptophan, and N-chloroacetyl-d-(alpha)-aminobutyric acid; when the induction effects of these compounds were compared with the effects of d-alanine as the nitrogen source and inducer, the resulting activities of d-amino acid oxidase per gram of dried yeast were 4.2, 2.1, and 1.5 times higher, respectively. The optimum concentration of the best inducer, N-carbamoyl-d-alanine, was 5 mM. This inducer could also be used in its racemic form. The induction was pH dependent. After cultivation of the yeast in a 50-liter bioreactor, d-amino acid oxidase activity of about 3,850 (mu)kat (231,000 U) was obtained. In addition, production of the d-amino acid oxidase was found to be significantly dependent on the metal salt composition of the medium. Addition of zinc ions was required to obtain high d-amino acid oxidase levels in the cells. The optimum concentration of ZnSO(inf4) was about 140 (mu)M.

Abstract
OBJECTIVES This study compared health service use and satisfaction with health care among older adults living in urban vs rural counties in North Carolina. METHODS A stratified random sample of 4162 residents of one urban and four rural counties of North Carolina was surveyed to determine urban/rural variation in inpatient and outpatient health service use, continuity of care and satisfaction with care, and barriers (transportation, cost) to care. RESULTS Inpatient and outpatient service use did not vary by residence in controlled analyses. Continuity of care was more frequent in rural counties. Transportation was not perceived as a barrier to health care more frequently in rural than in urban counties, but cost was a greater barrier to care among rural elderly people. CONCLUSIONS In this sample, older persons living in rural counties within reasonable driving distance of urban counties with major medical centers used health services as frequently and were as satisfied with their health care as persons in urban counties. Cost of care, however, was a significant and persistent barrier among rural elderly people, despite Medicare coverage.

Abstract
The use of selective decontamination of the digestive tract (SDD) to control infection in the intensive care unit (ICU) is reviewed. There are three basic patterns of infection in the ICU: primary endogenous, secondary endogenous, and exogenous. In exogenous infection, no microbial carriage precedes colonization and infection. In endogenous infection, infection is preceded by oropharyngeal or GI carriage. A primary endogenous infection is caused by an organism carried by the patient on admission to the ICU, whereas a secondary endogenous infection is caused by organisms acquired in the ICU. The traditional approach to infection control in the ICU has included frequent hand washing, limiting the use of agents for prophylaxis of stress-ulcer bleeding, and limiting the use of injectable antimicrobials to the treatment of infection in order to prevent resistance. The recognition that hand washing only partially reduces endogenous infection led to the use of nonabsorbable antimicrobials to abolish oropharyngeal and gastrointestinal carriage of potentially pathogenic microorganisms. In addition, the use of an injectable antimicrobial during the first four days in the ICU to control primary endogenous infection was considered not to lead to resistance as long as it was combined with nonabsorbable antimicrobials. Of 41 fully reported clinical trials of SDD, 33 showed a significant reduction of infectious morbidity among patients who received SDD. Of the 32 trials in which carriage of potential pathogens was a measured endpoint, 31 showed a reduction in carriage. Of the 24 studies in which resistance was an endpoint, 22 showed no increase in resistance associated with SDD. Only 10 of 35 trials that examined death showed a significant decrease in mortality. SDD, used in conjunction with traditional infection-control measures, diminishes microbial carriage and infectious morbidity in the ICU without increasing antimicrobial resistance.

Abstract
Enteric redmouth disease is described in chinook salmon (Oncorhynchus tshawytscha) at a state hatchery in Sand Ridge, Illinois. Biochemical, isoenzyme, and serological data indicated that the epizootic was caused by a sorbitol-fermenting Serovar 2 strain of Yersinia ruckeri. In laboratory experiments the isolate was pathogenic for both brook trout (Salvelinus fontinalis) and Atlantic salmon (Salmo salar).

Abstract
Although elusive, generalization of behavior change in autistic children is essential to obtaining maximum treatment effects. Using behaviorally based treatment and teachers and parents as trainers, generalization effects between home and school were measured on four behaviors: following instructions, washing, wiping bottom, and sharing toys. The results indicate that both settings were effective in establishing generalization. Behaviors treated in one setting generalized to another when children were provided with an opportunity for daily practice. Treatment with practice in other settings is possible in contrast to providing treatment on the same behavior in both settings.

Abstract
Leukocyte alkaline phosphatase (LAP) activity increases progressively during pregnancy, returning to non-pregnant levels 6 weeks post-partum. This enzymatic activity is under the influence of placental steroid hormones, thus reflecting placental function. LAP activity is thus a reflection of the dynamic relations between estrogenic, progestational and corticoid activity during pregnancy. LAP activity was studied in 60 women and in their 61 newborn infants at delivery and during the first five days of the puerperium. The Kaplow cytochemical technique was employed. The average maternal LAP score as well as the average newborn infant LAP score was considerably higher than the LAP score of the normal adult. The level of the enzyme in the maternal granulocytes was significantly higher than that of the newborn (Tab. I). During the first five days after labor, there was progressive decrease in the LAP score in the maternal and the newborn blood; on the fifth day the LAP scores of both were only slightly above the normal adult score (Figs. 1, 2). An inverse relation between the LAP score and the birth weight of the infant was found (Tab. III). These results confirm the view that LAP activity in the fetus in utero, are dependent on placental steroid function. The lower LAP values in the newborn, as compared to those of the mother are probably dependent on the lower newborn hormone levels. The significance of the relation between LAP scores and the infants birth weight is not clear.
