This is the author accepted manuscript. The final version is available from the American Medical Association via the DOI in this record.Importance: Effects of nutritional interventions on the prevention of major depressive disorder (MDD) in overweight adults are unknown.
Objective: To examine the effect of two nutritional strategies (multi-nutrient supplementation, food-related behavioral activation (F-BA) therapy) and their combination for prevention of a new MDD episode in overweight adults with subsyndromal depressive symptoms.
Design, setting, participants: This multicenter 2x2 factorial randomized clinical trial included overweight adults (BMI 25-40kg/m2) aged 18-75years with elevated depressive symptoms (Patient Health Questionnaire-9 (PHQ-9) scoresâĽ5) not meeting criteria for MDD episodes in the past 6 months from 4 European countries. 1025 adults were randomized between July-30-2015 and October-12-2016, and followed for 1 year (until October-13-2017).
Interventions: Daily multi-nutrient supplements (1412mg omega-3 fatty acids, 30Îźg selenium, 400Îźg folic acid, and 20Îźg D-3 vitamin plus 100mg calcium) versus placebo (blinded), and/or 21 individual and group F-BA sessions versus no F-BA (blinded to researchers), for one year. Participants were allocated to placebo without F-BA (n=257), placebo with F-BA (n=256), supplements without F-BA (n=256), and supplements with F-BA (n=256).
Main Outcomes and Measures: Primary outcome was cumulative 1-year onset of MDD measured with the Mini International Neuropsychiatric Interview after 3, 6 and 12 months. Logistic regression using effect-coded variables (-1 indicating control, +1 indicating intervention) evaluated intervention effects both individually and in combination (interaction) on MDD onset.
Results: Among 1025 participants (mean age 46.5y; 772 (75%) women; mean BMI 31.4kg/m2), 779 (76%) completed the trial.
During 12 month follow-up, 105 (10%) developed MDD (placebo without F-BA: 25 (9.7%), placebo with F-BA: 26 (10.2%), supplements without F-BA: 32 (12.5%), supplements with F-BA: 22 (8.6%).. Neither supplements (odds ratio (OR)=1.06; 95%-confidence interval (CI)=0.87-1.29), F-BA (OR=0.93; 95%CI=0.76-1.13), nor their combination (OR=0.93; 95%CI=0.76-1.14, p for interaction=0.48) affected MDD onset. Number of deaths/hospitalizations were for placebo without F-BA (n=0,n=24), placebo with F-BA (n=0,n=24), supplements without F-BA (n=0,n=26) and supplements with F-BA (n=1,n=24), respectively.
Conclusions and Relevance: Among overweight or obese adults with depressive symptoms, multi-nutrient supplementation compared with placebo and food-related behavioral activation therapy compared with no therapy did not reduce episodes of major depressive disorder during 1 year. These findings do not support the use of these interventions for prevention of major depressive disorder.

Treatment delay among tuberculosis patients in Tanzania: Data from the FIDELIS Initiative
<p>Abstract</p> <p>Background</p> <p>Several FIDELIS projects (Fund for Innovative DOTS Expansion through Local Initiatives to Stop TB) in Tanzania were conducted by the National Tuberculosis and Leprosy Programme (NTLP) during the years 2004-2008 to strengthen diagnostic and treatment services. These projects collected information on <it>treatment delay </it>and some of it was available for research purposes. With this database our objective was to assess the duration and determinants of treatment delay among new smear positive pulmonary tuberculosis (TB) patients in FIDELIS projects, and to compare delay according to provider visited prior to diagnosis.</p> <p>Methods</p> <p>Treatment delay among new smear positive TB patients was recorded for each patient at treatment initiation and this information was available and fairly complete in 6 out of 57 districts with FIDELIS projects enrolling patients between 2004 and 2007; other districts had discarded their forms at the time of analysis. It was analysed as a cross sectional study.</p> <p>Results</p> <p>We included 1161 cases, 10% of all patients recruited in the FIDELIS projects in Tanzania. Median delay was 12 weeks. The median duration of cough, weight loss and haemoptysis was 12, 8 and 3 weeks, respectively. Compared to Hai district Handeni had patients with longer delays and Mbozi had patients with shorter delays. Urban and rural patients reported similar delays. Patients aged 15-24 years and patients of 65 years or older had longer delays. Patients reporting contact with traditional healers before diagnosis had a median delay of 15 weeks compared to 12 weeks among those who did not. Patients with dyspnoea and with diarrhoea had longer delays.</p> <p>Conclusion</p> <p>In this patient sample in Tanzania half of the new smear positive pulmonary tuberculosis patients had a treatment delay longer than 12 weeks. Delay was similar in men and women and among urban and rural patients, but longer in the young and older age groups. Patients using traditional healers had a 25% longer median delay.</p
Patient-reported outcome measures for cancer caregivers: a systematic review
Purpose
Informal caregivers provide invaluable help and support to people with cancer. As treatments extend survival and the potential burdens on carers increase, there is a need to assess the impact of the role. This systematic review identified instruments that measure the impact of caregiving, evaluated their psychometric performance specifically in cancer and appraised the content.
Methods
A 2-stage search strategy was employed to: 1. identify instruments that measure the impact of caregiving, 2. run individual searches on each measure to identify publications evaluating psychometric performance in the target population. Searches were conducted in Medline, Embase, CINAHL and Psychinfo and restricted to English for instrument used and article language. Psychometric performance was evaluated for content and construct validity, internal consistency, test-retest reliability, precision, responsiveness and acceptability. Individual scale items were extracted and systematically categorised into conceptual domains.
Results
10 papers were included reporting on the psychometric properties of 8 measures. Although construct validity and internal consistency were most frequently evaluated, no study comprehensively evaluated all relevant properties. Few studies met our inclusion criteria so it was not possible to consider the psychometric performance of the measures across a group of studies. Content analysis resulted in 16 domains with 5 overarching themes: lifestyle disruption; wellbeing; health of the caregiver; managing the situation and relationships.
Conclusions
Few measures of caregiver impact have been subject to psychometric evaluation in cancer caregivers. Those that have do not capture well changes in roles and responsibilities within the family and career, indicating the need for a new instrument
Cancer and heart attack survivorsâ expectations of employment status: results from the English Longitudinal Study of Ageing
Background: Sociodemographic, health- and work-related factors have been found to influence return to work in cancer survivors. It is feasible though that behavioural factors, such as expectation of being at work, could also affect work-related outcomes. Therefore, the effect of earlier identified factors and expectation of being at work on future employment status in cancer survivors was explored. To assess the degree to which these factors specifically concern cancer survivors, a comparison with heart attack survivors was made. Methods: Data from the English Longitudinal Study of Ageing were used. Cancer and heart attack survivors of working age in the UK were included and followed up for 2 years. Baseline characteristics of both cancer and heart attack survivors were compared regarding employment status. Univariate and multivariate regression analyses were performed in survivors at work, and the interaction between independent variables and diagnose group was assessed. Results: In cancer survivors at work (N = 159), alcohol consumption, participating in moderate or vigorous sport activities, general health and participation were univariate associated with employment status at two-year followup. Only fair general health (compared to very good general health) remained statistically significant in the multivariate model (OR 0.31; 95% CI 0.13â0.76; p = 0.010). In heart attack survivors at work (N = 78), gender, general health and expectation of being at work were univariate associated with employment status at follow-up. Female gender (OR 0.03; 95% CI 0.00â0.57; p = 0.018) and high expectation of being at work (OR 10.68; 95% CI 1.23â93.92; p = 0.033) remained significant in the multivariate model. The influence of gender (p = 0.066) and general health (p = 0.020) regarding employment status was found to differ significantly between cancer and heart attack survivors. Conclusions: When predicting future employment status in cancer survivors in the UK, general health is the most relevant factor to consider. While expectation of being at work did not show any significant influence in cancer survivors, in heart attack survivors, it should not be disregarded though, when developing interventions to affect their employment status. Future research should focus on more specific measures for expectation, and additional behavioural factors, such as self-efficacy, and their effect on employment status
The acceptability of waiting times for elective general surgery and the appropriateness of prioritising patients
BACKGROUND: Problematic waiting lists in public health care threaten the equity and timeliness of care provision in several countries. This study assesses different stakeholders' views on the acceptability of waiting lists in health care, their preferences for priority care of patients, and their judgements on acceptable waiting times for surgical patients. METHODS: A questionnaire survey was conducted among 257 former patients (82 with varicose veins, 86 with inguinal hernia, and 89 with gallstones), 101 surgeons, 95 occupational physicians, and 65 GPs. Judgements on acceptable waiting times were assessed using vignettes of patients with varicose veins, inguinal hernia, and gallstones. RESULTS: Participants endorsed the prioritisation of patients based on clinical need, but not on ability to benefit. The groups had significantly different opinions (p < 0.05) on the use of non-clinical priority criteria and on the need for uniformity in the prioritisation process. Acceptable waiting times ranged between 2 and 25 weeks depending on the type of disorder (p < 0.001) and the severity of physical and psychosocial problems of patients (p < 0.001). Judgements were similar between the survey groups (p = 0.3) but responses varied considerably within each group depending on the individual's attitude towards waiting lists in health care (p < 0.001). CONCLUSION: The explicit prioritisation of patients seems an accepted means for reducing the overall burden from waiting lists. The disagreement about appropriate prioritisation criteria and the need for uniformity, however, raises concern about equity when implementing prioritisation in daily practice. Single factor waiting time thresholds seem insufficient for securing timely care provision in the presence of long waiting lists as they do not account for the different consequences of waiting between patients
Shot noise in mesoscopic systems
This is a review of shot noise, the time-dependent fluctuations in the
electrical current due to the discreteness of the electron charge, in small
conductors. The shot-noise power can be smaller than that of a Poisson process
as a result of correlations in the electron transmission imposed by the Pauli
principle. This suppression takes on simple universal values in a symmetric
double-barrier junction (suppression factor 1/2), a disordered metal (factor
1/3), and a chaotic cavity (factor 1/4). Loss of phase coherence has no effect
on this shot-noise suppression, while thermalization of the electrons due to
electron-electron scattering increases the shot noise slightly. Sub-Poissonian
shot noise has been observed experimentally. So far unobserved phenomena
involve the interplay of shot noise with the Aharonov-Bohm effect, Andreev
reflection, and the fractional quantum Hall effect.Comment: 37 pages, Latex, 10 figures (eps). To be published in "Mesoscopic

Identification of excreted iron superoxide dismutase for the diagnosis of Phtytomonas
An excreted iron superoxide dismutase (FeSODe) of pI 3.6 with a molecular weight of 28-30 kDa was detected in the in vitro culture of Phytomonas isolated from Euphorbia characias (SODeCHA) and from Lycopersicon esculentum (SODeTOM), in Grace's medium without serum. These FeSODe excreted into the medium had immunogenic capacity: the positivity of the anti-SODeCHA serum persisted to a dilution of 1/30,000, and for the anti-SODeTOM to 1/10,000 by Western blot. In addition, cross reaction was detected between the anti-SODe serum of Phytomonas isolated from E. characias against SODeTOM, and the anti-SODe serum from L. esculentum with SODeCHA. This characteristic offers the possibility of its use to diagnose plant trypanosomatids. The validation of the test was confirmed by experimental inoculation of tomato fruits with Phytomonas isolated from L. esculentum. At 7, 10, 15, and 21 days post infection, it was possible to detect the presence of the parasites with the anti-SODe serum of Phytomonas isolated from L. esculentum at a dilution of 1/250. These serological results were confirmed by visualization of the parasites by optical microscopy. The data of this study confirm that the SOD is sufficient to identify a trypanosomatid isolated from plants as belonging to the genus Phytomonas.Finacial support: ATP 2002/03: Circulation of Trypanosomatidae Project (CIRAD, France), grant BIO-2000-1429 (University of Granada, Spain)
