Further evidence that gender matters for GHG mitigation in the dairy sector: Analysis of survey data from central Kenya highlights interactive effects of gender and farm management practices on milk yield and GHG emission intensity

Consumption of dairy products in Sub-Saharan Africa is projected to increase significantly in the coming decades. As production increases, there will be an increasing need to reduce the environmental impacts of dairy production. One way to reduce the carbon footprint of milk production is to increase productivity: more productive cows use a greater proportion of feed energy and protein intake for milk production than less productive cows. Because more milk is produced for a given level of feed intake, the carbon footprint of milk can be reduced. Productivity may be increased by a range of management practices, such as improved breeds, use of higher quality feeds, animal health interventions and more. Often these measures are implemented as technology packages. For example, stall-feeding often involves adoption of improved dairy breeds and changes in feed sources and feed quality. Adoption of more intensive management practices is commonly linked to increased commercialization so that intensive production remains profitable. While most smallholders sell to informal markets, linking smallholders to the formal market (e.g. cooperatives and processing firms) is also seen as one way to incentivize and enable increased milk production. Thus, Kenya’s proposed dairy NAMA intends to promote intensification of production practices on farm to increase milk yields, and link dairy farmers to cooperatives and formal sector milk processors to strengthen market-based incentives for increased milk production (SDL 2017)

The impact of textual elements on the comprehensibility of drug label instructions (DLIs):A systematic review

IntroductionCorrect interpretation of drug labels instructions (DLIs) is needed for safe use and better adherence to prescribed drugs. DLIs are often too difficult for patients, especially for those with limited health literacy. What is yet unknown, is how specific textual elements in DLIs (e.g., the presentation of numbers, or use of medical jargon) and patients' health literacy skills are related to the comprehension of DLIs. In order to provide concrete directions for health professionals on how to optimize drug prescriptions, we performed a systematic review to summarize the available research findings on which textual elements facilitate or hinder the correct interpretation of DLIs in relation to patients' health literacy.MethodA systematic search was performed in PubMed, EMBASE, PsychINFO, and Smartcat (until April 2019) to identify studies investigating textual elements that facilitate or hinder the correct interpretation of DLIs in relation to patients' health literacy.ResultsA total of 434 studies were identified of which 28 studies met our inclusion criteria. We found that textual elements contributing to the correct interpretation of DLIs were: using explicit time periods in dosage instructions, using plain language, presenting numbers in a numerical format, and providing DLIs in patients' native language. Multistep instructions per instruction line, using abbreviations and medical jargon seem to hinder the correct interpretation of DLIs. Although health literacy was taken into account in a majority of the studies, none of them assessed the effectiveness of specific textual elements on patients' comprehensibility of DLIs.ConclusionBased on our findings, we provide an overview of textual elements that contribute to the correct interpretation of DLIs. Optimizing the textual instruction on drug labels may increase the safety and adherence to prescribed drugs, taking into account that a significant proportion of patients has low health literacy

Social support as a predictor of perceived health status in patients with multiple sclerosis

Objective: The main aim of this study was to investigate whether different levels of perceived social support are associated with different levels of perceived health status in multiple sclerosis (MS) patients. Methods: Two hundred and seven MS patients (38.4 +/- 10.6 years, 66.2% female) completed the Short-Form-36 Health Survey (SF-36) as the measure for perceived health status, and the perceived social support scale (PSSS) as the measure for social support. Functional disability was assessed using Kurtzke's expanded disability status scale (EDSS). The contribution of EDSS and PSSS for explaining the variance in SF-36 was investigated with multiple linear regression analysis. Results: Demographic variables and EDSS explained 44% of the variance of the physical health summary scale in the SF-36. Demographic variables, EDSS and PSSS front family and friends explained 24% of the variance in mental health summary scale in the SF-36. Results varied according to the multiple linear regression analyses of predictors of variance in the eight dimensions of the SF-36. Conclusion: PSSS from significant others was positively associated with general health dimension of perceived physical health status, while PSSS from family and friends was positively associated with perceived mental health status in MS patients. Practice implications: The results show the importance of supporting social ties and relationships between MS patients and others. (C) 2008 Elsevier Ireland Ltd. All rights reserved

A diet rich in fish oil and Leucine Ameliorates Hypercalcemia in tumour-induced cachectic mice

Background: Dietary supplementation with leucine and fish oil rich in omega-3 fatty acids docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) has previously been shown to reduce cachexia-related outcomes in C26 tumour-bearing mice. To further explore associated processes and mechanisms we investigated changes in plasma Ca2+ levels, the involvement of parathyroid hormone related protein (PTHrP), and its possible interactions with cyclooxygenase 2 (COX-2). Methods: CD2F1 mice were subcutaneously inoculated with C26 adenocarcinoma cells or sham treated and divided in: (1) controls, (2) tumour-bearing controls, and (3) tumour-bearing receiving experimental diets. After 20 days, body and organ masses and total plasma Ca2+ levels were determined. Furthermore, effects of DHA, EPA and leucine on production of PTHrP were studied in cultured C26 cells. Results: The combination of leucine and fish oil reduced tumour-associated hypercalcemia. Plasma Ca2+ levels negatively correlated with carcass mass and multiple organ masses. DHA was able to reduce PTHrP production by C26 cells in vitro. Results indicate that this effect occurred independently of COX-2 inhibition. Conclusion: Our results suggest that cancer-related hypercalcemia may be ameliorated by a nutritional intervention rich in leucine and fish oil. The effect of fish oil possibly relates to a DHA-induced reduction of PTHrP excretion by the tumour

Long-chain n-3 polyunsaturated fatty acid ingestion for the stimulation of muscle protein synthesis in healthy older adults

This review aims to critically evaluate the efficacy of long-chain ո-3 polyunsaturated fatty acid (ո-3 PUFA) ingestion in modulating muscle protein synthesis (MPS), with application to maintaining skeletal muscle mass, strength and function into later life. Ageing is associated with a gradual decline in muscle mass, specifically atrophy of type II fibres, that is exacerbated by periods of (in)voluntary muscle disuse. At the metabolic level, in otherwise healthy older adults, muscle atrophy is underpinned by anabolic resistance which describes the impaired MPS response to nonpharmacological anabolic stimuli, namely physical activity/exercise and amino acid provision. Accumulating evidence implicates a mechanistic role for n-3 PUFA in upregulating MPS under stimulated conditions (postprandial state or following exercise) via incorporation of eicosapentaenoic (EPA) and docosahexaenoic acid (DHA) into the skeletal muscle phospholipid membrane. In some instances, these changes in MPS with chronic ո-3 PUFA ingestion have translated into clinically relevant improvements in muscle mass, strength and function; an observation evidently more prevalent in healthy older women than men. This apparent sexual dimorphism in the adaptive response of skeletal muscle metabolism to EPA and DHA ingestion may be related to a greater propensity for females to incorporate ո-3 PUFA into human tissue and/or the larger dose of ingested ո-3 PUFA when expressed relative to body mass or lean body mass. Future experimental studies are warranted to characterise the optimal dosing and duration of ո-3 PUFA ingestion in order to prescribe tailored recommendations regarding n-3 PUFA nutrition for healthy musculoskeletal ageing into later life

SketchingDIS:Hand-drawn Sketching in HCI

Hand-drawn sketches can be an easy way for HCI researchers to communicate and express ideas, as well as to document, explore and communicate concepts between the researcher and user, collaborator, manager or client. These sketches are fast, lightweight, easy to create, and -- by varying their fidelity -- they can be used in all stages of the HCI research and design process. Here, we aim to explore themes around sketching in HCI with the aim of producing tangible outputs in the form of visual records, articles and papers that review and promote this technique in HCI as a field: 'SketchingDIS: Hand-drawn sketching in HCI' SketchingDIS.wordpress.com, a one-day workshop will bring together researchers from various disciplines that have incorporated hand-drawn sketching into their everyday research practice, to share knowledge and methodologies, generate ideas, practice collaborative sketching, and to discuss the future of hand-drawn sketching in HCI and DIS itself

Posttransplant Anemia as a Prognostic Factor of Mortality in Kidney-Transplant Recipients

Background. Findings on the association between posttransplant anemia (PTA) andmortality in posttransplant patients are scarce. This study explored whether PTA shortly after kidney transplantation (KT) predicts mortality at up to 10 years' follow-up, stratified for chronic kidney disease (CKD) stages. Methods. PTA was divided into 3 categories according to the hemoglobin (Hb) value: severe (Hb <10 g/dl), mild (10.0 g/dl = 12 g/dl). CKD stages were estimated using the CKD-EPI formula and divided into 2 groups: CKD1-2 and CKD3-5. Cox regression, stratified according to CKD, was performed to identify whether different categories of PTA predicted mortality in KT recipients. Results. Age, being female, and both mild and severe PTA contributed significantly to the Cox regression model on mortality in CKD1-2. In the Cox regression model for mortality in CKD3-5, age and severe PTA contributed significantly to this model. Conclusion. PTA shortly after KT increased the risk of mortality at up to 10 years' follow-up. Even mild PTA is associated with a 6-fold higher risk of mortality and severe PTA with a 10-fold higher risk of mortality in CKD1-2. Clinical evaluation and treatment of anemia might reduce the higher risk of mortality in patients with PTA in early stages of CKD after KT

Effect of high-dose dexamethasone on perioperative lactate levels and glucose control:a randomized controlled trial

INTRODUCTION: Blood lactate levels are increasingly used to monitor patients. Steroids are frequently administered to critically ill patients. However, the effect of steroids on lactate levels has not been adequately investigated. We studied the effect of a single intraoperative high dose of dexamethasone on lactate and glucose levels in patients undergoing cardiac surgery. METHODS: The Dexamethasone for Cardiac Surgery (DECS) trial was a multicenter randomized trial on the effect of dexamethasone 1 mg/kg versus placebo on clinical outcomes after cardiac surgery in adults. Here we report a pre-planned secondary analysis of data from DECS trial participants included at the University Medical Center Groningen. The use of a computer-assisted glucose regulation protocol--Glucose Regulation for Intensive care Patients (GRIP)--was part of routine postoperative care. GRIP aimed at glucose levels of 4 to 8 mmol/L. Primary outcome parameters were area under the lactate and glucose curves over the first 15 hours of ICU stay (AUC₁₅). ICU length of stay and mortality were observed as well. RESULTS: The primary outcome could be determined in 497 patients of the 500 included patients. During the first 15 hours of ICU stay, lactate and glucose levels were significantly higher in the dexamethasone group than in the placebo group: lactate AUC₁₅ 25.8 (13.1) versus 19.9 (11.2) mmol/L × hour, P <0.001 and glucose AUC₁₅ 126.5 (13.0) versus 114.4 (13.9) mmol/L × hour, P <0.001. In this period, patients in the dexamethasone group required twice as much insulin compared with patients who had received placebo. Multivariate and cross-correlation analyses suggest that the effect of dexamethasone on lactate levels is related to preceding increased glucose levels. Patients in the placebo group were more likely to stay in the ICU for more than 24 hours (39.2%) compared with patients in the dexamethasone group (25.0%, P = 0.001), and 30-day mortality rates were 1.6% and 2.4%, respectively (P = 0.759). CONCLUSIONS: Intraoperative high-dose dexamethasone increased postoperative lactate and glucose levels in the first 15 hours of ICU stay. Still, patients in the dexamethasone group had a shorter ICU length of stay and similar mortality compared with controls. TRIAL REGISTRATION: ClinicalTrials.gov NCT00293592 .
