Abstract
BACKGROUND The WHO and the World Bank ask countries to report the national volume of surgery. This report describes these data for Sweden, a high-income country. METHODS In an 8-year population-based observational cohort study, all inpatient and outpatient care in the public and private sectors was detected in the Swedish National Patient Register and screened for the occurrence of surgery. The entire Swedish population was eligible for inclusion. All patients attending healthcare for any disease were included. Incidence rates of surgery and likelihood of surgery were calculated, with trends over time, and correlation with sex, age and disease category. RESULTS Almost one in three hospitalizations involved a surgical procedure (30·6 per cent). The incidence rate of surgery exceeded 17 480 operations per 100 000 person-years, and at least 58·5 per cent of all surgery was performed in an outpatient setting (range 58·5 to 71·6 per cent). Incidence rates of surgery increased every year by 5·2 (95 per cent c.i. 4·2 to 6·1) per cent (P < 0·001), predominantly owing to more outpatient surgery. Women had a 9·8 (95 per cent c.i. 5·6 to 14·0) per cent higher adjusted incidence rate of surgery than men (P < 0·001), mainly explained by more surgery during their fertile years. Incidence rates peaked in the elderly for both women and men, and varied between disease categories. CONCLUSION Population requirements for surgery are greater than previously reported, and more than half of all surgery is performed in outpatient settings. Distributions of age, sex and disease influence estimates of population surgical demand, and should be accounted for in future global and national projections of surgical public health needs.

Abstract
SETTING The impact of the genetic characteristics of Mycobacterium tuberculosis on the clustering of multidrug-resistant tuberculosis (MDR-TB) has not been analyzed together with clinical and demographic characteristics. OBJECTIVE To determine factors associated with genotypic clustering of MDR-TB in a community-based study. DESIGN We measured the proportion of clustered cases among MDR-TB patients and determined the impact of clinical and demographic characteristics and that of three M. tuberculosis genetic characteristics: lineage, drug resistance-associated mutations, and rpoA and rpoC compensatory mutations. RESULTS Of 174 patients from California and Texas included in the study, the number infected by East-Asian, Euro-American, Indo-Oceanic and East-African-Indian M. tuberculosis lineages were respectively 70 (40.2%), 69 (39.7%), 33 (19.0%) and 2 (1.1%). The most common mutations associated with isoniazid and rifampin resistance were respectively katG S315T and rpoB S531L. Potential compensatory mutations in rpoA and rpoC were found in 35 isolates (20.1%). Hispanic ethnicity (OR 26.50, 95%CI 3.73-386.80), infection with an East-Asian M. tuberculosis lineage (OR 30.00, 95%CI 4.20-462.40) and rpoB mutation S531L (OR 4.03, 95%CI 1.05-23.10) were independent factors associated with genotypic clustering. CONCLUSION Among the bacterial factors studied, East-Asian lineage and rpoB S531L mutation were independently associated with genotypic clustering, suggesting that bacterial factors have an impact on the ability of M. tuberculosis to cause secondary cases.

Abstract
BACKGROUND Multiple sclerosis (MS) and allergies are both considered to be related to imbalanced Th1 and Th2 immune responses. Previous studies evaluating the relationship between MS and allergies provide conflicting results. OBJECTIVE To assess allergies and asthma as risk factors for MS and as predictors of MS relapses in a pediatric cohort. METHODS The environment and genetic risk factors for pediatric MS study is a national case-control project with 16 participating US sites. An environmental questionnaire is used that includes history of allergies in the first five years of life. Case-control data are entered in the pediatric MS Network database and cases at 12 of the 16 sites enter relapse data prospectively. Annualized relapse rate was calculated for patients with follow-up and adjusted for age at disease onset, gender, race, ethnicity, and use of disease-modifying therapy (DMT). RESULTS We included 271 cases (mean age at disease onset of 15.7years and 62% female) and 418 controls. Relapse data were available for 193 cases. There was no difference in prevalence of allergies or asthma between cases and controls. Patients with food allergies had fewer relapses compared to patients without food allergies (0.14 vs 0.48, p=0.01). CONCLUSIONS While allergies and asthma are not associated with pediatric MS, cases with food allergies have fewer relapses compared to those without food allergies.

Abstract
BACKGROUND Diarrhea is the most frequent morbidity affecting kenneled dogs in animal shelters. Diarrhea impacts animal welfare and the finances of the shelter as they must treat, clean, and house affected animals until recovered. HYPOTHESIS/OBJECTIVES Supplementing dogs entering an animal shelter with a probiotic-prebiotic, known as a synbiotic, will decrease the incidence of diarrhea. ANIMALS Seven hundred and seventy-three dogs entering an animal shelter in the United Kingdom. METHODS A prospective double-blind, randomized, placebo-controlled trial. RESULTS Statistical difference was found between the groups across 3 measures of diarrhea incidence. First, the mean percentage of scored days per dog that were scored as diarrhea throughout their stay was 2.0% in the synbiotic group and 3.2% in the placebo group (P = .0022). Second, the occurrence of diarrhea within the first 14 days' stay was 18.8% in the synbiotic product group and 27.2% in the placebo group (P = .0008). Third, the occurrence of ≥2 consecutive days of diarrhea within the first 14 days' stay was 4.6% in the synbiotic product group and 8.0% in the placebo group (P = .0300). CONCLUSIONS AND CLINICAL IMPORTANCE Supplementing healthy dogs entering an animal shelter with a synbiotic supplement significantly decreased the incidence of diarrhea in this trial. Animal shelters can use synbiotic supplements to improve animal welfare and decrease costs involved in cleaning and housing animals as well as potentially decreasing veterinary intervention.

Abstract
This study explored the relationship between stress and team climate in care staff working with learning disabled people. A questionnaire was used to collect information in four community residences. The results suggested that there were no significant differences between mean levels of stress, anxiety and depression in different groups of staff. However, variability was seen within the participants across the four facilities. An examination of the relationship between stress and team climate suggested that the higher the stress the worse the perceived team climate. A correlational analysis indicated that the way individuals view aspects of the organisational climate of these facilities had some impact upon their well-being. The implications of these findings are discussed.

Abstract
BACKGROUND the smallest worthwhile effect (SWE) of an intervention is the smallest treatment effect that justifies the costs, risks and inconveniences associated with that health intervention. OBJECTIVE to estimate the SWE of exercise programs designed to prevent falls among older people and to compare estimates derived by two methodological approaches. STUDY DESIGN AND SETTING discrete choice experiment (n = 220) and benefit-harm trade-off (subsample n = 66) methods were used. PARTICIPANTS community-dwelling older people who reported a past fall or a mobility limitation answered online or face-to-face questionnaires. RESULTS a substantial proportion of participants (82% in the discrete choice experiment and 50% in the benefit-harm trade-off study) did not consider that participation in the proposed exercise programs would be worthwhile, even if it reduced their risk of falling to 0%. Among remaining participants, the average SWE of participation in an exercise program was an absolute reduction in the risk of falling of 35% (standard deviation [SD] = 13) in the discrete choice experiment and 16% (SD = 11) in the benefit-harm trade-off study. CONCLUSIONS many participants did not consider the hypothetical falls' risk reduction of the proposed exercise programs to be worth the associated costs and inconveniences. Greater community awareness of the fall prevention effects of exercise for older people is required.

Abstract
Periodic discharges of high concentrations of aluminium (Al) causing fish kills and other adverse effects occur worldwide in waterways affected by coastal lowland acid sulfate soils (CLASS). The exchangeability - a metal's ability to readily transfer between the soil solid- and solution-phases - of Al in these soils is therefore of particular importance as it has implications for metal transport, plant availability and toxicity to living organisms. In the present study, the concentrations of isotopically exchangeable Al (E values) were measured in 27 CLASS and compared with common salt extractions (i.e. KCl and CuCl2) used to estimate exchangeable soil pools of Al. E values of Al were high in the soils, ranging from 357 to 3040 mg·kg(-1). Exchangeable concentrations estimated using 1 M KCl were consistently lower than measured E values, although a reasonable correlation was obtained between the two values (E=1.68×AlKCl, r(2)=0.66, n=25). The addition of a 0.2 M CuCl2 extraction step improved the 1:1 agreement between extractable and isotopically exchangeable Al concentrations, but lead to significant mobilisation of non-isotopically exchangeable Al in surficial 'organic-rich' CLASS having E values<1000 mg·kg(-1). It was concluded that currently used (i.e. 1 M KCl) methodology severely underestimates exchangeable Al and total actual acidity values in CLASS and should be corrected by a factor similar to the one determined here.

Abstract
BACKGROUND People with intellectual disabilities (ID) are rarely asked about their experiences as users of psychological services and little is known about the views of clients with ID who have undergone cognitive behavioural therapy (CBT). This study aimed to gather the views of adults with ID who had recently taken part in a cluster randomised control trial (RCT) of a staff-delivered manualised CBT anger management group intervention. METHOD A qualitative method, Interpretative Phenomenological Analysis (IPA), was employed and eleven participants were interviewed. The interviews took place after the intervention, within two weeks of the end of the group, to gain an understanding of service users' experiences of participating in a CBT group. RESULTS IPA of the interview transcripts indicated that the intervention was experienced as effective and enjoyable and a number of themes were identified including: 'the importance of relationships', 'a new me', 'new and improved relationships', 'presenting myself in a positive light' and 'what the group didn't change'. CONCLUSIONS The results will be discussed in the context of applying group CBT for adults with ID and implications for service development.

Abstract
BACKGROUND Anger and aggression among adults with intellectual disability (ID) are associated with a range of adverse consequences for their well-being and that of their family or staff carers. The aims were to evaluate the effectiveness of an anger management intervention for adults with mild to moderate ID and to evaluate the costs of the intervention and its impact on health and social care resource use. This paper is concerned with the latter aim. METHODS A cluster-randomised controlled trial was conducted involving day services for adults with ID in Scotland, England and Wales. Incremental costs of delivering the intervention and its impact on subsequent total health and social care package costs were calculated. Full data comparing costs between baseline and follow-up 10 months later were collected for 67 participants in the intervention arm and 62 participants in the control arm. Cost differences between the groups at follow-up, adjusted for baseline levels, were calculated using non-parametric bootstrapping controlling for clustering. RESULTS The mean hourly excess cost of intervention over treatment as usual was £12.34. A mean adjusted cost difference of £22.46 per person per week in favour of the intervention group was found but this was not statistically significant. CONCLUSIONS The baseline-adjusted cost difference at follow-up would result in a fairly immediate compensation for the excess costs of intervention, provided the difference is not a statistical artefact. Further research is needed to clarify the extent to which it might represent a real saving in service support costs.

Abstract
The influence of wastewater treatment plant (WWTP) effluents from one microelectronic industrial zone on element concentrations and partitioning in river water was investigated. The stepwise membrane filtration is used to distinguish different size fractions including large particulate (>18 μm), particulate (0.2-18 μm), colloidal/nanoparticle (10 kDa-0.2 μm) and truly dissolved fractions (<10 kDa) in river water samples and WWTP effluents. Results demonstrated that anthropogenic inputs (WWTP effluents and industrial area) had an important influence on concentrations and partitioning of some elements in river water. Mass balance results showed that membrane filtration processes could realize a good fractionation for many elements (good recoveries) in water samples. Flux decline during 0.2 μm and 10 kDa filtrations were analyzed, and corresponding fouling mechanisms are discussed.
