Experiences with improved cookstoves in Southern Africa

This study explores user experiences with improved cookstoves, drawing on findings from household surveys conducted in South Africa, Mozambique, Malawi and Zambia. Investigations were conducted on fuel and stove preferences; experiences with improved biomass cookstoves; the rationale for fuel and stovestacking subsequent to the initial uptake of improved biomass cookstoves; and aspirations for energy and fuel use among improved biomass cookstove users. Significant differences were identified in the perceived benefits of improved biomass cookstoves in the four countries and their priorities, with the most important benefits being fuel and cost savings. These would affect the reference frames within which end-users adopt improved biomass cookstoves. Local circumstances and diverse sets of priorities that affect household decisions need to be considered when promoting or rolling out improved cookstove initiatives

Association of Education and Intracranial Volume With Cognitive Trajectories and Mortality Rates Across the Alzheimer Disease Continuum

OBJECTIVE: To investigate relationships of education and intracranial volume (factors related to cognitive versus brain reserve, respectively) with cognitive trajectories and mortality in individuals with biomarker-defined Alzheimer's disease (AD). METHODS: We selected 1,298 amyloid-β-positive memory clinic patients with subjective cognitive decline (SCD, n=142), mild cognitive impairment (MCI, n=274) and AD dementia (n=882) from the Amsterdam Dementia Cohort. All participants underwent baseline MRI and neuropsychological assessment, and 68% received cognitive follow-up (median=2.3 years, interquartile range=2.4). Mortality data were collected from the Central Public Administration. In the total sample and stratified by disease stage (i.e., SCD/MCI versus dementia), we examined education and intracranial volume as predictors of baseline and longitudinal cognitive performance on five cognitive domains [memory, attention, executive, language and visuospatial functions] (linear mixed models) and time-to-death (Cox proportional hazard models). Analyses were adjusted for age, sex, whole-brain gray matter atrophy and MRI field strength. RESULTS: Education and intracranial volume showed consistent positive associations with baseline cognition across disease stages. Longitudinally, we observed a relationship between higher education and faster cognitive decline among dementia patients on global cognition, memory, executive function and language (range β=-0.06-[-0.13], all p<0.05). Furthermore, in the total sample, both higher education and intracranial volume related to lower mortality risk (hazard ratio=0.84 and 0.82, respectively, p<0.05). CONCLUSIONS: In this amyloid-β-positive memory clinic sample, both reserve factors were positively associated with baseline cognition, whereas only education related to longitudinal cognition (i.e., accelerated decline among higher-educated patients with dementia). Moreover, higher education and intracranial volume both moderately attenuated overall mortality risk in AD

The effectiveness of aerobic training, cognitive behavioural therapy, and energy conservation management in treating MS-related fatigue: The design of the TREFAMS-ACE programme

Background: TREFAMS is an acronym for TReating FAtigue in Multiple Sclerosis, while ACE refers to the rehabilitation treatment methods under study, that is, Aerobic training, Cognitive behavioural therapy, and Energy conservation management. The TREFAMS-ACE research programme consists of four studies and has two main objectives: (1) to assess the effectiveness of three different rehabilitation treatment strategies in reducing fatigue and improving societal participation in patients with MS; and (2) to study the neurobiological mechanisms of action that underlie treatment effects and MS-related fatigue in general.Methods/Design: Ambulatory patients (n = 270) suffering from MS-related fatigue will be recruited to three single-blinded randomised clinical trials (RCTs). In each RCT, 90 patients will be randomly allocated to the trial-specific intervention or to a low-intensity intervention that is the same for all RCTs. This low-intensity intervention consists of three individual consultations with a specialised MS-nurse. The trial-specific interventions are Aerobic Training, Cognitive Behavioural Therapy, and Energy Conservation Management. These interventions consist of 12 individual therapist-supervised sessions with additional intervention-specific home exercises. The therapy period lasts 16 weeks. All RCTs have the same design and the same primary outcome measures: fatigue - measured with the Checklist Individual Strength, and participation - measured with the Impact on Participation and Autonomy questionnaire. Outcomes will be assessed 1 week prior to, and at 0, 8, 16, 26 and 52 weeks after randomisation. The assessors will be blinded to allocation. Pro- and anti-inflammatory cytokines in serum, salivary cortisol, physical fitness, physical activity, coping, self-efficacy, illness cognitions and other determinants will be longitudinally measured in order to study the neurobiological mechanisms of action.Discussion: The TREFAMS-ACE programme is unique in its aim to assess the effectiveness of three rehabilitation treatments. The programme will provide important insights regarding the most effective tre

Fostering patient-centredness by following patients outside the clinical setting: an interview study

BACKGROUND: Patient-centredness is considered a core competency for health professionals. To support faculty in designing courses focused on patient-centredness, an understanding of how educational interventions lead to patient-centredness is required. This study aims to show how learning mechanisms, which potentially contribute to patient-centredness, are triggered. METHODS: Thirty-five third-year medical students at the UMC Utrecht followed four different patients for two years. The intervention took place in an out-of-hospital setting. Students visited patients in their home circumstances and accompanied them to clinical events. Twelve students were interviewed. The realist approach was used to construct configurations which relate components of the intervention to the context and learning mechanisms. RESULTS: Following patients in their home circumstances for a prolonged period supported the development of meaningful relationships between students and patients and provided continuity. In the context of a meaningful relationship and continuity, mechanisms contributing to learning patient-centredness were triggered. The most important learning mechanisms found in this study were: reflecting, contextualising disease in a real persons' life, broadening perspectives and engaging with the patients. CONCLUSIONS: Learning mechanisms are triggered by continuity and by meaningful student-patient relationships. These can be enhanced by an out-of-hospital setting and longitudinal contact. Thus, a relationship between students and patients is an important enabler for the development of patient-centredness

Nationwide Outcome of Tailored Surgery for Symptomatic Chronic Pancreatitis based on Pancreatic Morphology:Validation of the International guidelines

OBJECTIVE: To determine the nationwide use and outcome of tailored surgical treatment for symptomatic chronic pancreatitis (CP) as advised by recent guidelines.SUMMARY BACKGROUND DATA: Randomized trials have shown that surgery is superior to endoscopy in patients with symptomatic CP, although endoscopy remains popular Recent guidelines advice to "tailor surgery" based on pancreatic morphology meaning that the least extensive procedure should be selected based on pancreatic morphology. However, nationwide, and multicenter studies On tailored surgery for symptomatic CP are lacking.METHODS: Nationwide multicenter retrospective analysis of consecutive patients undergoing surgical treatment for symptomatic CP in all seven Dutch university medical centers (2010-2020). Outcomes included volume trend, major complications, 90-day mortality, postoperative opioid use and clinically relevant pain relief. Surgical treatment was tailored based on the size of the main pancreatic duct and pancreatic head (e.g. surgical drainage for a dilated pancreatic duct, and normal size pancreatic head).RESULTS: Overall, 381 patients underwent surgery for CP: 127 surgical drainage procedures ( 33%; mostly extended lateral pancreaticojejunostomy), 129 duodenum-preserving pancreatic head resections (DPPHR, 34%, mostly Frey), and 125 formal pancreatic resections (33%, mostly distal pancreatectomy). The annual surgical volume increased slightly (Pearson r=0.744). Mortality (90-day) occurred in 6 patients (2%), and was non-significantly lower after surgical drainage (0%, 3%, 2%; P =0.139). Major complications (12%, 24%, 26%; P =0.012), postoperative pancreatic fistula grade B/C (0%, 3%, 22%; P =0.038), surgical reintervention (4%, 16%, 12%; P =0.006), and endocrine insufficiency ( 14%, 21%, 43%; P &lt;0.001) occurred less often after surgical drainage. After a median follow-up of 11 months [IQR 3-23] good rates of clinically relevant pain relief ( 83%, 69%, 80%; P =0.082) were observed and 81% of opioid users had stopped using (83%, 78%, 84%, P =0.496).CONCLUSION: The use of surgery for symptomatic CP increased over the study period. Drainage procedures were associated with the best safety profile and excellent functional outcome, highlighting the importance of tailoring surgery based on pancreatic morphology.</p

Relationship of neutrophil-to-lymphocyte ratio, in addition to C-reactive protein, with cardiovascular events in patients with type 2 diabetes

Aim: To quantify the relationship of neutrophil-to-lymphocyte ratio (NLR) with cardiovascular events and all-cause mortality in patients with type 2 diabetes (T2D), independent of C-reactive protein (CRP). Methods: Patients with T2D from the UCC-SMART-cohort were studied using multivariable-adjusted Cox regression. The relationship of NLR and CRP with vascular events (cerebrovascular events, myocardial infarction and vascular death) and all-cause mortality was quantified. Results: During 10,833 person-years, 232 vascular events and 302 deaths occurred in 1,239 patients with T2D. Risk of vascular events and all-cause mortality increased per standard deviation (SD) in NLR (hazard ratio (HR) 1.27; 95 % confidence interval (CI):1.11–1.46) and 1.15; 95 % CI:1.02–1.30) after adjustment for CRP. CRP was not associated with vascular events after adjustment for NLR, (HR per SD 1.03; 95 % CI: 0.90–1.19), but was associated with all-cause mortality (HR per SD 1.18; 95 % CI: 1.04–1.33). Notably, NLR was related to vascular events in patients with CRP < 2 mg/L (HR per unit 1.45; 95 % CI: 1.19–1.77). Conclusion: In patients with T2D, NLR is related to higher risk of CVD and all-cause mortality, independently from CRP. NLR is related to CVD even when CRP is low, indicating that NLR is a marker of CVD-risk in addition to CRP. Both NLR and CRP are independently related to all-cause mortality in T2D patients
