Abstract
Background Cholera epidemics occur frequently in low-income countries affected by concurrent humanitarian crises. Evaluations of these epidemic response remains largely unpublished and there is a need to generate evidence on response efforts to inform future programmes. This review of MSF cholera epidemic responses aimed to describe the main characteristics of the cholera epidemics and related responses in these three countries, to identify challenges to different intervention strategies based on available data; and to make recommendations for epidemic prevention and control practice and policy. Methods Case studies from the Democratic Republic of Congo, Malawi and Mozambique were purposively selected by MSF for this review due to the documented burden of cholera in each country, frequency of cholera outbreaks, and risk of humanitarian crises. Data were extracted on the characteristics of the epidemics; time between alert and response; and, the delivery of health and water, sanitation and hygiene interventions. A Theory of Change for cholera response programmes was built to assess factors that affected implementation of the responses. Results and conclusions 20 epidemic response reports were identified, 15 in DRC, one in Malawi and four in Mozambique. All contexts experienced concurrent humanitarian crises, either armed conflict or natural disasters. Across the settings, median time between the date of alert and date of the start of the response by MSF was 23 days (IQR 14–41). Almost all responses targeted interventions community-wide, and all responses implemented in-patient treatment of suspected cholera cases in either established health care facilities (HCFs) or temporary cholera treatment units (CTUs). In three responses, interventions were delivered as case-area targeted interventions (CATI) and four responses targeted households of admitted suspected cholera cases. CATI or delivery of interventions to households of admitted suspected cases occurred from 2017 onwards only. Overall, 74 factors affecting implementation were identified including delayed supplies of materials, insufficient quantities of materials and limited or lack of coordination with local government or other agencies. Based on this review, the following recommendations are made to improve cholera prevention and control efforts: explore improved models for epidemic preparedness, including rapid mobilisation of supplies and deployment of trained staff; invest in and strengthen partnerships with national and local government and other agencies; and to standardise reporting templates that allow for rigorous and structured evaluations within and across countries to provide consistent and accessible data.

Abstract
INTRODUCTION Household contacts of cholera cases are at a greater risk of Vibrio cholerae infection than the general population. There is currently no agreed standard of care for household contacts, despite their high risk of infection, in cholera response strategies. In 2018, hygiene kit distribution and health promotion was recommended by Médecins Sans Frontières for admitted patients and accompanying household members on admission to a cholera treatment unit in the Democratic Republic of Congo. METHODS To investigate the effectiveness of the intervention and risk factors for cholera infection, we conducted a prospective cohort study and followed household contacts for 7 days after patient admission. Clinical surveillance among household contacts was based on self-reported symptoms of cholera and diarrhoea, and environmental surveillance through the collection and analysis of food and water samples. RESULTS From 94 eligible households, 469 household contacts were enrolled and 444 completed follow-up. Multivariate analysis suggested evidence of a dose-response relationship with increased kit use associated with decreased relative risk of suspected cholera: household contacts in the high kit-use group had a 66% lower incidence of suspected cholera (adjusted risk ratio (aRR) 0.34, 95% CI 0.11 to 1.03, p=0.055), the mid-use group had a 53% lower incidence (aRR 0.47, 95% CI 0.17 to 1.29, p=1.44) and low-use group had 22% lower incidence (aRR 0.78, 95% CI 0.24 to 2.53, p=0.684), compared with household contacts without a kit. Drinking water contamination was significantly reduced among households in receipt of a kit. There was no significant effect on self-reported diarrhoea or food contamination. CONCLUSION The integration of a hygiene kit intervention to case-households may be effective in reducing cholera transmission among household contacts and environmental contamination within the household. Further work is required to evaluate whether other proactive localised distribution among patients and case-households or to households surrounding cholera cases can be used in future cholera response programmes in emergency contexts.

Abstract
Background Cholera remains a leading cause of infectious disease outbreaks globally, and a major public health threat in complex emergencies. Hygiene kits distributed to cholera case-households have previously shown an effect in reducing cholera incidence and are recommended by Médecins Sans Frontières (MSF) for distribution to admitted patients and accompanying household members upon admission to health care facilities (HCFs). Methods This process evaluation documented the implementation, participant response and context of hygiene kit distribution by MSF during a 2018 cholera outbreak in Kasaï-Oriental, Democratic Republic of Congo (DRC). The study population comprised key informant interviews with seven MSF staff, 17 staff from other organisations and a random sample of 27 hygiene kit recipients. Structured observations were conducted of hygiene kit demonstrations and health promotion, and programme reports were analysed to triangulate data. Results and conclusions Between Week (W) 28-48 of the 2018 cholera outbreak in Kasaï-Oriental, there were 667 suspected cholera cases with a 5% case fatality rate (CFR). Across seven HCFs supported by MSF, 196 patients were admitted with suspected cholera between W43-W47 and hygiene kit were provided to patients upon admission and health promotion at the HCF was conducted to accompanying household contacts 5-6 times per day. Distribution of hygiene kits was limited and only 52% of admitted suspected cholera cases received a hygiene kit. The delay of the overall response, delayed supply and insufficient quantities of hygiene kits available limited the coverage and utility of the hygiene kits, and may have diminished the effectiveness of the intervention. The integration of a WASH intervention for cholera control at the point of patient admission is a growing trend and promising intervention for case-targeted cholera responses. However, the barriers identified in this study warrant consideration in subsequent cholera responses and further research is required to identify ways to improve implementation and delivery of this intervention.

Abstract
Introduction In a semi-urban setting in the Democratic Republic of Congo, this study aims to understand the dynamic of a typhoid fever (TF) outbreak and to assess: a) the existence of hot spots for TF transmission and b) the difference between typhoid cases identified within those hot spots and the general population in relation to socio-demographic characteristics, sanitation practice, and sources of drinking water. Methods This was a retrospective analysis of TF outbreaks in 2011 in Kikwit, DRC using microbiological analysis of water sources and a structured interview questionnaire. Results There were a total of 1430 reported TF cases. The outbreak’s epidemic curve shows earliest and highest peak attack rates (AR) in three military camps located in Kikwit (Ebeya 3.2%; Ngubu 3.0%; and Nsinga 2.2%) compared to an average peak AR of 0.6% in other affected areas. A total 320 cases from the military camps and the high burden health areas were interviewed. Typhoid cases in the military camps shared a latrine with more than one family (P<0.02). All tap water sources in both the military camps and general population were found to be highly contaminated with faecal coliforms. Conclusion The role of military camps in Kikwit as early hotspots of TF transmission was likely associated with lower sanitary and hygiene conditions. The proximity of camps to the general population might have been responsible for disseminating TF to the general population. Mapping of cases during an outbreak could be crucial to identify hot spots for transmission and institute corrective measures.

Abstract
Freshwater ponds deliver a broad range of ecosystem services (ESS). Taking into account this broad range of services to attain cost-effective ESS delivery is an important challenge facing integrated pond management. To assess the strengths and weaknesses of an ESS approach to support decisions in integrated pond management, we applied it on a small case study in Flanders, Belgium. A Bayesian belief network model was developed to assess ESS delivery under three alternative pond management scenarios: intensive fish farming (IFF), extensive fish farming (EFF) and nature conservation management (NCM). A probabilistic cost-benefit analysis was performed that includes both costs associated with pond management practices and benefits associated with ESS delivery. Whether or not a particular ESS is included in the analysis affects the identification of the most preferable management scenario by the model. Assessing the delivery of a more complete set of ecosystem services tends to shift the results away from intensive management to more biodiversity-oriented management scenarios. The proposed methodology illustrates the potential of Bayesian belief networks. BBNs facilitate knowledge integration and their modular nature encourages future model expansion to more encompassing sets of services. Yet, we also illustrate the key weaknesses of such exercises, being that the choice whether or not to include a particular ecosystem service may determine the suggested optimal management practice.

Abstract
OBJECTIVES Renal cell carcinoma (RCC) accounts for 2·4% of all new cancers in Belgium. Over the past decade, the armamentarium for systemic therapy of metastatic RCC (mRCC) has undergone important changes with implementation of targeted therapies directed against pathways involved in the pathogenesis of RCC. We describe first-line treatment choice of a group of patients in 9 Belgian oncology centres between October 2009 and November 2012. METHODS A clinical report form was established to assess patient characteristics, Karnofsky performance score, Memorial Sloan-Kettering Cancer Center risk criteria (MSKCC) and first-line therapy of mRCC patients. Choice of therapy and starting dose was analyzed before and after reimbursement of pazopanib in Belgium. RESULTS Ninety-six patients were eligible for the study. Non-smokers accounted for 53% of the patients. Seventy-three per cent of the patients had 0 or 1 MSKCC criteria in the group of patients that started treatment more than 1 year after initial diagnosis. In the group of patients that started therapy less than 1 year after diagnosis, 85% had 2 or more MSKCC criteria. This difference was statistically significant (P<0·0001). Overall distribution of the first-line therapies consisted of 43% sunitinib, 33% pazopanib, 14% temsirolimus, 7% everolimus and 3% sorafenib. Seventeen (18%) out of 96 patients started at a reduced dose level. CONCLUSION This report shows that the guidelines for the start of first-line treatment in mRCC in 9 centres in Belgium were applied most of the time: a tyrosine kinase inhibitor was the first treatment choice for most patients while temsirolimus was an option for poor prognosis patients. In the majority of patients standard dose levels were initiated, although in some patients adaptation of dosage/treatment schedule was recorded.

Abstract
Metastatic breast cancer (MBC) remains an incurable disease, despite major advances in the treatment in the past 10-12 years. Data on real life overall survival in a non-selected group containing all metastatic breast cancer patients are hard to find in the literature, as is the correlation of their survival with prognostic factors and treatment. This article provides overall survival data for all patients treated for MBC in a single-centre non-academic hospital. Survival data have been correlated with frequently used prognostic factors (subtype, age at diagnosis, M-status at diagnosis, metastases-free interval, and grade). It also gives an insight in the treatments given to and response rates in this population of MBC patients without selection bias representing the real life situation. A total of 169 patients were analysed. Mean survival from metastases is 31·8 months. Overall survival is better for the luminal subtypes, for younger age, for patients with a longer metastases-free interval, and for a lower grade. A small difference in survival has been seen in favour of the patients who represent immediately with metastases. With a larger sample size, we expect these factors to be prognostic significant. The luminal subtypes have a clear predisposition to metastasize in the bone, whereas visceral metastases occur more frequently and earlier in the hormone receptor-negative tumours. Brain metastases do occur in about half of the triple negative tumours and Her2/neu-positive tumours. Overall response rate to first-line chemotherapy was 56% in consecutive lines of treatment, a continuous clinical benefit exceeding 50% when selecting fit patients. This article represents a unique and valuable description of medical oncologists' real-life daily practice in MBC patients, with a clinical outcome that certainly compares to the sparse data provided in the literature.

Abstract
Von Hippel-Lindau (VHL) disease is an autosomal dominant inherited disorder with a predisposition to develop a wide variety of lesions: retinal, cerebellar, spinal and medullar hemangioblastomas, renal cell carcinomas, phaeochromocytomas, and renal, pancreatic and epididymal cysts are the most frequent manifestations of the disease. The prevalence of VHL disease has been estimated to be 1 per 36,000 persons. We report the case of a 68-year-old woman with Von Hipple-Lindau disease who developed high fever with pulmonary and hepatic lesions proven to be Hodgkin's disease on biopsy. To our knowledge, this is the first report of Hodgkin's disease in a patient with Von Hippel-Lindau.
