Project Opti-Milk: Optimisation and Comparison of High Yield and Low Input Milk Production Strategies on Pilot Farms in the Lowlands of Switzerland

Compared to other European countries milk production costs in Switzerland are high. Therefore Swiss milk producers must drastically reduce their costs. The high yield strategy (HY) and the full grazing (FG) or low-cost strategy appear most promising, at least for the lowland regions. Although the basic knowledge is available for both strategies, they have been applied very little in Switzerland in a consistent and optimised form

Leveraging research partnerships to achieve the 2030 agenda : experiences from North-South cooperation

Transnational research partnerships are considered fundamental for supporting research and creating shared knowledge for sustainable development. They enable the acquisition and global sharing of high-quality information and create shared knowledge and capacity. This paper aimed to identify the enabling factors of such partnerships. In a survey carried out by the authors of this article, partnerships were perceived most beneficial when they provided access to new key features such as funding, technology and training. Compliance with research partnership principles, combined with funds and shared interests, was seen to further enhance the longevity of partnerships. Upon consulting the recent peer-reviewed literature, it became clear that research was lacking with regard to optimising the framework and performance of research partnerships, despite galloping technological progress in other areas of sustainable development. We believe that technological opportunities could be better harnessed to enable the concept of partnership to evolve and move towards transformative research for the advancement of sustainable development

Safety and efficacy of olesoxime in patients with type 2 or non-ambulatory type 3 spinal muscular atrophy: A randomised, double-blind, placebo-controlled phase 2 trial

Background: Spinal muscular atrophy (SMA) is a progressive motor neuron disease causing loss of motor function and reduced life expectancy, for which limited treatment is available. We investigated the safety and efficacy of olesoxime in patients with type 2 or non-ambulatory type 3 SMA. Methods: This randomised, double-blind, placebo-controlled, phase 2 study was done in 22 neuromuscular care centres in Belgium, France, Germany, Italy, Netherlands, Poland, and the UK. Safety and efficacy of olesoxime were assessed in patients aged 3-25 years with genetically confirmed type 2 or non-ambulatory type 3 SMA. A centralised, computerised randomisation process allocated patients (2:1 with stratification by SMA type and centre) to receive olesoxime (10 mg/kg per day) in an oral liquid suspension or placebo for 24 months. Patients, investigators assessing outcomes, and sponsor study personnel were masked to treatment assignment. The primary outcome measure was change from baseline compared with 24 months between the two treatment groups in functional domains 1 and 2 of the Motor Function Measure (MFM D1 + D2) assessed in the full analysis population. A shorter, 20-item version of the MFM, which was specifically adapted for young children, was used to assess patients younger than 6 years. Safety was assessed in the intention-to-treat population. The trial is registered with ClinicalTrials.gov, number NCT01302600. Findings: The trial was done between Nov 18, 2010, and Oct 9, 2013. Of 198 patients screened, 165 were randomly assigned to olesoxime (n=108) or placebo (n=57). Five patients in the olesoxime group were not included in the primary outcome analysis because of an absence of post-baseline assessments. The change from baseline to month 24 on the primary outcome measure was 0\ub718 for olesoxime and -1\ub782 for placebo (treatment difference 2\ub700 points, 96% CI -0\ub725 to 4\ub725, p=0\ub70676). Olesoxime seemed to be safe and generally well tolerated, with an adverse event profile similar to placebo. The most frequent adverse events in the olesoxime group were pyrexia (n=34), cough (n=32), nasopharyngitis (n=25), and vomiting (n=25). There were two patient deaths (one in each group), but these were not deemed to be related to the study treatment. Interpretation: Olesoxime was safe at the doses studied, for the duration of the trial. Although the primary endpoint was not met, secondary endpoints and sensitivity analyses suggest that olesoxime might maintain motor function in patients with type 2 or type 3 SMA over a period of 24 months. Based on these results, olesoxime might provide meaningful clinical benefits for patients with SMA and, given its mode of action, might be used in combination with other drugs targeting other mechanisms of disease, although additional evidence is needed.

Uncertainties and controversies in axillary management of patients with breast cancer

The aims of this Oncoplastic Breast Consortium and European Breast Cancer Research Association of Surgical Trialists initiative were to identify uncertainties and controversies in axillary management of early breast cancer and to recommend appropriate strategies to address them. By use of Delphi methods, 15 questions were prioritized by more than 250 breast surgeons, patient advocates and radiation oncologists from 60 countries. Subsequently, a global virtual consensus panel considered available data, ongoing studies and resource utilization. It agreed that research should no longer be prioritized for standardization of axillary imaging, de-escalation of axillary surgery in node-positive cancer and risk evaluation of modern surgery and radiotherapy. Instead, expert consensus recommendations for clinical practice should be based on current evidence and updated once results from ongoing studies become available. Research on de-escalation of radiotherapy and identification of the most relevant endpoints in axillary management should encompass a meta-analysis to identify knowledge gaps, followed by a Delphi process to prioritize and a consensus conference to refine recommendations for specific trial designs. Finally, treatment of residual nodal disease after surgery was recommended to be assessed in a prospective register

Compression hosiery for occupational leg symptoms and leg volume: a randomized crossover trial in a cohort of hairdressers

OBJECTIVE: Occupational leg symptoms are highly prevalent in the general population and impair the psychic state of health. We investigated hairdressers, a cohort exposed to prolonged standing during work, in a randomized crossover trial. We hypothesized that hairdressers wearing low-strength compression hosiery would benefit from less leg volume increase and discomfort. METHODS: One hundred and eight hairdressers were randomized to wear medical compression stockings (MCS; 15-20 mmHg) in a crossover study. The effect of MCS on symptoms and on lower leg volume was compared with no compression treatment. Symptoms were assessed with a comprehensive questionnaire, categorized using factor analysis with varimax rotation and correlated with leg volume changes. RESULTS: Wearing MCS reduced the symptom score for pain and feelings of swelling (range 0-4) by an average of 0.22 (12%, P < 0.001). Sleep disturbance, feeling of unattractive legs and depressiveness improved with MCS compared with no MCS. Subjects initially obliged to refrain from wearing stockings showed a significant decrease of pain and feelings of swelling as well (by 0.10 [6%], P = 0.015). Wearing MCS was associated with a decrease of lower leg volume by an average of 19 mL (P < 0.001), with preference in older hairdressers (P < 0.001). The effects of wearing MCS on symptoms and on leg volume were not correlated with each other. CONCLUSIONS: Individuals working in a standing profession experience leg pain, feelings of swelling, heaviness and various other disturbing feelings. These symptoms can be alleviated by wearing low-strength MCS

A case-control study of sporadic Creutzfeldt-Jakob disease in Switzerland: analysis of potential risk factors with regard to an increased CJD incidence in the years 2001-2004

BACKGROUND: In 2001, the observed annual mortality from Creutzfeldt-Jakob disease (CJD) in Switzerland increased from less than 1.5 to 2.6 per million inhabitants. An underlying cause could not be identified. METHODS: To analyse potential risk factors for sCJD in Switzerland, close relatives of 69 sCJD-patients and 224 frequency age-matched controls were interviewed in a case-control study using a standardised questionnaire. 135 potential risk factors including socio-demographics, medical history, occupation and diet were analysed by logistic regression adjusting for age, sex and education. RESULTS: sCJD patients were more likely to have travelled abroad, worked at an animal laboratory, undergone invasive dental treatment, orthopaedic surgery, ophthalmologic surgery after 1980, regular GP visits, taken medication regularly, and consumed kidney. No differences between patients and controls were found for residency, family history, and exposure to environmental and other dietary factors. CONCLUSION: Although some factors were significantly more frequent among sCJD-cases, this study did not reveal specific explanations for the increased incidence of deaths due to sporadic CJD observed in Switzerland since 2001. Results have to be interpreted with caution due to multiple testing and possible recall bias in association with a long incubation period. The most plausible reason for the increase in Swiss sCJD cases after 2000 is an improved case ascertainment. Therefore, underreporting of cases might well have occurred before the year 2001, and the "real" yearly incidence of sCJD might not be lower than, but rather above 2 per million inhabitants
