    Full Text Available Cysticercosis, caused by Taenia solium eggs, is a zoonotic disease whose consequences can be severe especially in the cerebral localisation (neuorcysticercosis. Indeed, neurocysticercosis is the first cause of epilepsy amongst the infectious etiology group. Following the increase of epilepsy cases in Kinshasa and Bas-Congo, it was important to assess the fraction attributable to neurocysticercosis especially as data on cysticercosis in Democratic Republic Of Congo (DRC dating from 1970.A joint study between veterinary and human doctors was conducted in the provinces of Bas-Congo and Kinshasa between 2008 and 2010. Blood samples were collected from the general population, patients with epilepsy and pigs. These samples were analysed using ELISA antigen in the laboratory of the Institute of Tropical Medicine in Antwerp. Patients positive to ELISA antigen took the CT scan exam for the confirmation of neurocysticercosis. In the province of Kinshasa, of 530 epileptic patients, 6.3% were identified as neurocysticercosis cases. Out of a total of 498 pigs, 38.9% were positive for cysticercosis. In the province of Bas- Congo, of 943 inhabitants from Malanga village, 21.6% were positive with predominance in males (26.4% versus 17.5%. A total of 145 pigs from 5 villages were examined and 41.2% found positive.We can conclude that cysticercosis in the DRC has been neglected for a long time and cysticercosis could be a real major public health problem. Prospective studies addressing the consequences of cysticercosis in communities are needed in order to prevent epilepsy due to neurocysticercosis.

    Given the important contribution of urban consumption in bushmeat trade, information on bushmeat sales in urban markets can provide valuable insights for understanding the dynamics of this trade and its implications for conservation and food security. We monitored bushmeat traded in the market...... bushmeat was one of the cheapest sources of protein available year-round, together with caterpillars, which were only available during the rainy season, and pork. Prices of other domestic meat were significantly higher. This study identified an increase in the market of highly threatened species...... of Kisangani (the provincial capital of the Province Orientale in the Democratic Republic of Congo) and compared data collected in surveys in 2002 and 2008–2009.

    During July–November 2014, the Democratic Republic of the Congo underwent its seventh Ebola virus disease (EVD) outbreak. The etiologic agent was Zaire Ebola virus; 66 cases were reported (overall case-fatality rate 74.2%). Through a retrospective observational study of confirmed EVD in 25 patients admitted to either of 2 Ebola treatment centers, we described clinical features and investigated correlates associated with death. Clinical features were mainly generic. At admission, 76% of patients had >1 gastrointestinal symptom and 28% >1 hemorrhagic symptom. The case-fatality rate in this group was 48% and was higher for female patients (67%). Cox regression analysis correlated death with initial low cycle threshold, indicating high viral load. Cycle threshold was a robust predictor of death, as were fever, hiccups, diarrhea, dyspnea, dehydration, disorientation, hematemesis, bloody feces during hospitalization, and anorexia in recent medical history. Differences from other outbreaks could suggest guidance for optimizing clinical management and disease control. PMID:27533284

    Human taeniasis was investigated in Lao People's Democratic Republic (Lao PDR) between 2000 and 2011 as part of the nation's helminthiasis survey. A total of 55,038 inhabitants, including 29,846 school children, were examined using the Kato-Katz and scotch-tape anal swab method, and morphological observation of adult worms. Molecular identification of Taenia tapeworms was performed by multiplex PCR or DNA sequence analysis of the mitochondrial cox1 gene. Taenia eggs were present at a rate of 1.5% (845/55,038) in the subject population. Adult tapeworms were identified as T. solium or T. saginata by analyzing the collectable stool specimens (n=126). Three specimens identified as T. solium were found in Luang Prabang, while the remaining 123 specimens, which were T. saginata, were found in Bokeo, Bolikhamxay, Champasak, Houaphan, Khammouane, Luang Namta, Luang Prabang, Oudomxay, Phongsaly, Saysomboune, Saravane, Savannakhet, Xayaboury, Xekong, Xieng Khouang Province, and Vientiane Municipality.

  12. The state of emergency care in Democratic Republic of Congo

    Full Text Available The Democratic Republic of Congo (DRC is the second largest country on the African continent with a population of over 70 million. It is also a major crossroad through Africa as it borders nine countries. Unfortunately, the DRC has experienced recurrent political and social instability throughout its history and active fighting is still prevalent today. At least two decades of conflict have devastated the civilian population and collapsed healthcare infrastructure. Life expectancy is low and government expenditure on health per capita remains one of the lowest in the world. Emergency Medicine has not been established as a specialty in the DRC. While the vast majority of hospitals have emergency rooms or salle des urgences, this designation has no agreed upon format and is rarely staffed by doctors or nurses trained in emergency care. Presenting complaints include general and obstetric surgical emergencies as well as respiratory and diarrhoeal illnesses. Most patients present late, in advanced stages of disease or with extreme morbidity, so mortality is high. Epidemics include HIV, cholera, measles, meningitis and other diarrhoeal and respiratory illnesses. Lack of training, lack of equipment and fee-for-service are cited as barriers to care. Pre-hospital care is also not an established specialty. New initiatives to improve emergency care include training Congolese physicians in emergency medicine residencies and medic ranger training within national parks.

    In October 1994, at Geneva, the United States and the Democratic People`s Republic of Korea (DPRK) signed an Agreed Framework as a first step toward resolving international concerns about nuclear activities in the DPRK. This Agreement, when implemented, will ultimately lead to the complete dismantlement of those aspects of the DPRK`s nuclear program, including reprocessing-related facilities, that have undermined the viability of the international nuclear non-proliferation regime and the stability of the Asia-Pacific region. The essence of the Agreement is that the DPRK will take near-term action to cease the activities of concern and permit some International Atomic Energy Agency (IAEA) verification inspection. In the future, it will dismantle its production reactors and accept full-scope IAWA safeguards. In return, the United Stated agreed to lead an international effort to supply the DPRK with light-water reactors which are less of proliferation concern than are graphite-moderated production reactors. Until the first LWR is in operation the DPRK will receive shipments of heavy oil to replace the energy lost by shutting down the production reactors.

    2002-01-01

    After the Second World War the development of medical mycology in Germany had taken a very different course in the east and west parts depending on the political division. In this respect our contribution deals with the situation in the former German Democratic Republic. Efficient mycological centres were founded step by step almost in all medical universities on the basis of the mycological laboratories in dermatological hospitals competent for diagnostic work, but also for teaching and scientific research. In this context biologists were the main stay of mycology, they finally were integrated to the same degree in the universities like physicians. The effectiveness of the Gesellschaft für Medizinische Mykologie der DDR (GMM), its board of directors and its working groups as well as the topics of human and animal mycology during this period are described. Especially the merger of the GMM with the Deutschsprachige Mykologische Gesellschaft after the reunification of Germany without problems and the kind co-operation of Prof. Dr. Johannes Müller during this procedure are emphasized.

  15. Ocular pentastomiasis in the Democratic Republic of the Congo.

    Full Text Available Ocular pentastomiasis is a rare infection caused by the larval stage of pentastomids, an unusual group of crustacean-related parasites. Zoonotic pentastomids have a distinct geographical distribution and utilize reptiles or canids as final hosts. Recently, an increasing number of human abdominal infections have been reported in Africa, where pentastomiasis is an emerging, though severely neglected, tropical disease. Here we describe four ocular infections caused by pentastomids from the Democratic Republic of the Congo. Two cases underwent surgery and an Armillifer grandis infection was detected by morphological and molecular approaches. Thus far, 15 other cases of ocular pentastomiasis have been reported worldwide. Twelve cases were caused by Armillifer sp., recorded almost exclusively in Africa, where such infections occur as a consequence of hunting and consuming snakes, their final hosts. Seven further cases were caused by Linguatula serrata, a cosmopolitan pentastomid whose final hosts are usually canids. Intraocular infections caused permanent visual damage in 69% and a total loss of vision in 31% of reported cases. In contrast, ocular adnexal cases had a benign clinical course. Further research is required to estimate the burden, therapeutic options and pathogenesis of this neglected disease.

    Diphtheria is a vaccine-preventable disease. When vaccination coverage and population immunity are low, outbreaks can occur. We investigated a diphtheria outbreak in Lao People's Democratic Republic that occurred during 2012-2013 and highlighted challenges in immunization services delivery to children in the country. We reviewed diphtheria surveillance data from April 1, 2012-May 31, 2013. A diphtheria case was defined as a respiratory illness consisting of pharyngitis, tonsillitis, or laryngitis, and an adherent tonsillar or nasopharyngeal pseudomembrane. To identify potential risk factors for diphtheria, we conducted a retrospective case-control study with two aged-matched neighborhood controls per case-patient in Houaphan Province, using bivariate analysis to calculate matched odds ratio (mOR) with 95% confidence intervals (CI). Reasons for non-vaccination among unvaccinated persons were assessed. Sixty-two clinical cases of diphtheria and 12 diphtheria-related deaths were reported in seven of 17 provinces. Among case-patients, 43 (69%) were diphtheria case-patients from Houaphan province and 79 matched-controls were enrolled. Five (12%) case-patients and 20 (25%) controls had received DTP3 (mOR=0.4, CI=0.1-1.7). No diphtheria toxoid-containing vaccine was received by 20 (48%) case-patients and 38 (46%) controls. Among case-patients and controls with no DTP dose, 43% of case-patients and 40% of controls lacked access to routine immunization services. Suboptimal DTP3 coverage likely caused the outbreak. To prevent continued outbreaks, access to routine immunization services should be strengthened, outreach visits need to be increased, and missed opportunities need to be minimized. In the short term, to rapidly increase population immunity, three rounds of DTP immunization campaign should be completed, targeting children aged 0-14years in affected provinces.

  17. Background Report on Eastern Democratic Republic of the Congo

    Each month, approximately 45,000 people die from violence, hunger, disease, and other effects of displacement as a result of war in the Democratic Republic of the Congo (DRC). The country is often said to be plagued by a 'resource curse.' During each period in history since its discovery by the West, the DRC has possessed the resources the world craves and the world has sought these without regard for the consequences to the Congolese people. The catastrophic consequences of Congo's history of natural resource exploitation are the direct and indirect death of millions of Congolese people. The current war in Congo is multi-causal in nature but explanations are often reduced to describing it as an ethic conflict based on objective grievance. Objective grievance such as inequality, ethnic tensions, land disputes, and lack of democracy do exist, but they are neither necessary nor sufficient to explain the cause of the violent conflict, and more importantly, they fall short in explaining why this conflict has continued for years. The reality is the conflict is an economic war in which the trade of conflict minerals, gold and the 3Ts (tin, tantalum, tungsten), is directly linked to the financial sustainability of the groups fighting each other in eastern DRC. Objective grievance is a by-product of the conflict, used to create a false but plausible moral justification to continue violence. This paper examines the history of conflict in the DRC and the socio-economic variables contributing to the current war fought over conflict minerals.

    Full Text Available Their nature and functions make political parties central to democratic governance especially in the new democracies of Africa that face the challenge of building strong and enduring democratic institutions. It is accepted that the existing trend in most of these democracies of one big party dominating the political space weakens democracy and undermines its prospects for consolidation. Big parties—usually the ruling ones—exhibit tendencies such as absence of internal democracy that are antithetical to democratic governance. While observations such as these are incontestable, there is little understanding into the nature, character, ideology, and internal structure of big parties generally. In this article, I attempt to address this concern. Specifically, I examine the nature, structure, and ideology of the Peoples Democratic Party (PDP, Nigeria’s ruling party at the federal level with considerable strength at local level between 1999 and 2015. Relying on data obtained from multiple sources, I investigate the process of its formation, the nature of its ideology, internal organization, its electoral strength, and how absence of internal democracy contributed significantly to its defeat in 2015 general elections.

    2012-01-01

    The Democratic Republic of the Congo has been appropriately acknowledged as "the rape capital of the world." While the country has been trapped in conflict, the use of rape as a weapon of war has been rampant and unyielding. The sexual violence inflicted upon women has been nothing less than brutal and destructive, physically, socially, and psychologically. This paper analyzes the use of rape as a weapon of war in the Congo, taking into context the ongoing war, cultural and social situations that facilitate its existence, and the many consequences the victims are forced to endure. Drawing information from various academic journals, articles, and field research from international organizations, this paper paints a concise picture of the sexual atrocities occurring in the Democratic Republic of the Congo.

    2016-05-01

    Full Text Available This paper examines the nature and impacts of two information intervention radio programmes broadcast on Radio Okapi—the radio service of the UN Mission in the Democratic Republic of Congo. A matched randomization technique was used to assign Rwandan Hutus and Congolese autochthons in South Kivu to listen to either of the two programmes within their naturalistic contexts for 13 months. At the end of the treatment, participants’ perceptions of barriers to peace; descriptive and prescriptive interventions; victimhood and villainity; opportunities for personal development and civic engagement; and knowledge of repatriation processes were assessed in 16 focus groups across four contexts. The study concludes that international media intervention programmes that provide robust information and a platform for objective analyses within a multiple narrative and participatory framework can enhance greater engagement with nascent democratic reforms, positive perception of long term opportunities for personal development and empathy with the ethnic Other.

  12. First Order Dominance Analysis: Child Wellbeing in the Democratic Republic of Congo.

    Science.gov (United States)

    Nanivazo, Malokele

    This paper performs a multidimensional first order dominance analysis of child wellbeing in the Democratic Republic of Congo (DRC). This methodology allows the ordinal ranking of the 11 provinces of the DRC in terms of their wellbeing based upon the probability of their domination. This empirical application obviates the need to adopt a weighting scheme for the deprivation indicators or to rely on the signs of other cross-derivatives for comparison. We execute a bootstrap linear programming algorithm on seven deprivation indicators for three age groups of children derived from the DRC 2007 Standard Demographic and Health Survey. The results reveal widespread disparities in child wellbeing in the DRC.

    The Democratic Republic of the Congo (DRC) is tremendously wealthy. Abundant in gold, diamonds, tantalum, tin, copper, zinc and cobalt, the natural resources in Africa's third largest country are not equally benefiting the people. The DRC should sustainably be making use of their natural resources to develop the country, whose health, education and transport systems all suffer to this day from the effects of conflict. Instead, the DRC is divided with rebels, corrupt governments and foreign investors all fighting in one way or another for control over the country's wealth. The following article focuses on the emergence of rape as a strategy of war in the DRC.

    Patient files, textbooks and published articles of the time show that the wide range of psychiatric therapies of the 1950s and 1960s was also used in the early German Democratic Republic (GDR). The use of insulin coma therapy, cardiazol and electroconvulsive therapies and especially of leucotomy in the GDR must not only be seen in the context of the international development and debate concerning these therapies up to the introduction of psychopharmaceutic therapy but also, in a similar way as in the Federal Republic of Germany, in relation to the locally sometimes different availability of insulin and cardiazol in the post-war period, different schools of academic thought and scientific research interest and priorities of the clinics concerned.

    To assess the antibiotic prescribing practices of doctors working in the Lao People's Democratic Republic and their knowledge of local antibiotic resistance patterns. Doctors attending morning meetings in 25 public hospitals in four provinces were asked to complete a knowledge, attitude and practice survey. The questionnaire contained 43 multiple choice questions that the doctor answered at the time of the meeting. The response rate was 83.4% (386/463). Two hundred and seventy doctors (59.8%) declared that they had insufficient information about antibiotics. Only 14.0% (54/386) recognized the possibility of cephalosporin cross-resistance in methicillin-resistant Staphylococcus aureus. Most participants had no information about local antibiotic resistance for Salmonella Typhi (211/385, 54.8%) and hospital-acquired pneumonia (253/384, 65.9%). Unnecessary antibiotic prescriptions were considered as harmless by 115 participants and 148 considered locally-available generic antibiotics to be of poor quality. Nearly three-quarters (280/386) of participants agreed that it was difficult to select the correct antibiotics. Most participants (373/386) welcomed educational programmes on antibiotic prescribing and 65.0% (249/383) preferred local over international antibiotic guidelines. Doctors in the Lao People's Democratic Republic seem to favour antibiotic prescribing interventions. Health authorities should consider a capacity building programme that incorporates antibiotic prescribing and hospital infection control.

    Full Text Available Background. To determine clinical profile and management of retinoblastoma among children at Kinshasa in Democratic Republic of Congo. Patients and methods. The medical records of patients with a diagnosis of retinoblastoma seen at the University Hospital of Kinshasa from January 1985 till December 2005 were retrospectively reviewed. Demographic profile, clinical data, modes of treatment and outcome were analysed. Results. A total of 49 children, of whom 40 had adequate data on record were identified as retinoblastoma (28 males and 12 females. Nine cases had bilateral disease. The median age at the first symptoms was 9 months (range, 1 month to 6 years for unilateral retinoblastoma and 18 months (range, 1 month to 3.5 years for bilateral retinoblastoma. The median age at the first oncology consultation was 2.4 years (range, 6 months to 6 years for unilateral retinoblastoma and 2.4years (range, 9 months to 4 years for bilateral disease. Leukokoria was present in 67.5% of subjects. Seventy-five percent abandoned the treatment. The mortality was 92.5%. Conclusion. In Democratic Republic of Congo, retinoblastoma remains a life threatening disease characterized by late referral to a specialized unit and affordability of chemotherapy; all leading to an extension of the disease and high mortality.

    Romaniuk, Anatole

    2011-01-01

    The article explores how geography, history, and society have shaped childbearing behaviors over the last half-century, and how they are now being reshaped by modernity and the exigencies of urban life, in the democratic Republic of the Congo. The decline of prolonged postpartum abstinence and involuntary childlessness initially raised fertility to high levels (6–7 children per woman). More recently, socioeconomic differentials in fertility have emerged, suggesting that the country may be entering a phase of fertility decline. A full-blown transition, however, seems still a remote prospect. Supported both by cultural traditions and by economic rationality, Congo's people remain largely convinced of the benefits of many children for their own and their kin's security. While an eventual fertility transition may be taken for granted, the article examines the many hurdles, contradictions, and tensions that will have to be overcome to achieve that outcome.

    The conflict in the Eastern Democratic Republic of Congo (DRC) has been particularly devastating for children and has been typified by high levels of sexual and gender-based violence (SGBV). In this study, we seek to characterize the patterns and impact of sexual violence on children in the Eastern DRC. Semi-structured questionnaires were administered among a convenience sample of women armed combatants decreased by 70% between 2004 and 2008. Qualitative analysis of the narratives revealed common themes, such as physical signs and symptoms among SGBV survivors (23.9%), pregnancy resulting from rape (19.3%), perpetrators being brought to justice (18.3%), and neighbourhood men as perpetrators (17.7%). Children in the Eastern DRC continue to face significant threats of sexual violence. By understanding the patterns of this violence, local and international approaches could be more effectively implemented to protect these vulnerable children.

    Full Text Available This qualitative research was conducted in three Northern provinces of the Lao People’s Democratic Republic with the aim of investigating the traditional art of khub music and its conservation and inheritance. Data were collected from documents and field research using interviews, observation and focus group discussions as data collection tools. The results show that Morkhub, musicians, teachers, students and audiences all contribute to the success or failure of conservation and inheritance of traditional Laotian music. The majority of problems with conservation stem from a lack of interest and the dilution of local culture with modern Western influences. As a result of this investigation, a four-point plan was proposed to standardize and support future conservation of khub traditions by inclusion in the education system.

  8. Battles on women's bodies: war, rape and traumatisation in eastern Democratic Republic of Congo.

    2011-01-01

    Rape has been used as a weapon in the conflict in eastern Democratic Republic of Congo (DRC) in unprecedented ways. Research into the phenomenon of war-rape is limited, particularly in this context. The aim of this study was to explore perceptions of local leaders in eastern DRC concerning rape and raped women in the war context. Local leaders were chosen for their ability to both reflect and influence their constituencies. Interviews were conducted with 10 local leaders and transcripts subjected to qualitative content analysis. The study suggests that mass raping and the methods of perpetration created a chaos effectively destroying communities and the entire society and that humanitarian aid was often inappropriate. Furthermore, an exclusive focus on raped women missed the extent of traumatisation entire communities suffered. More significantly, the lack of political will, corruption, greed and inappropriate aid creates a tangled web serving to intensify the war. This complexity has implications for humanitarian interventions including public health.

    Opisthorchiasis is a neglected tropical disease, yet it is of considerable public health importance in Southeast Asia given the predilection for chronically infected persons to develop cholangiocarcinoma. We evaluated a handheld microscope for the diagnosis of Opisthorchis viverrini in a community-based setting in Lao People's Democratic Republic in comparison with conventional light microscopy. In stool samples collected from 104 individuals, handheld microscopy revealed a sensitivity of 70.6% and a specificity of 89.5% for O. viverrini infection. Pearson's correlation for quantitative fecal egg counts between the two devices was 0.98 (95% confidence interval: 0.98-0.99). With small adjustments to further increase diagnostic sensitivity, a handheld microscope may become a helpful tool to screen for O. viverrini and other helminth infections in public health settings.

    Studies report that between 6 per cent and 29 per cent of survivors of sexual violence in eastern Democratic Republic of the Congo (DRC) are rejected by their families and communities. This research project was designed to provide insights into survivors' experiences of stigmatisation and rejection. Surveys were conducted with 310 women as they sought psychosocial services in eastern DRC. In total, 44.3 per cent of women reported suffering rejection after sexual violence. The majority of women felt that their status in the household (58.0 per cent) and community (54.9 per cent) diminished after rape. The odds of rejection were greater among women reporting ongoing displacement, pregnancy owing to sexual violence, worsening family relations, and diminished community status. This work highlights the extremely high levels of loss associated with the war in eastern DRC, particularly among survivors of sexual violence. The rejection of a survivor of rape has concrete and devastating psychosocial consequences.

    1997-12-12

    Human monkeypox is a severe smallpox-like illness caused by monkeypox virus (MPV); monkeypox occurs in sporadic outbreaks, and infection is enzootic among squirrels and monkeys in the rainforests of western and central Africa. In 1996, cases of monkeypox were reported from villages in the Katako-Kombe Health Zone, Kasai Oriental, Zaire (i.e., Democratic Republic of Congo). The World Health Organization (WHO), in collaboration with CDC, investigated this outbreak and identified 92 suspected cases with onset during February 1996-February 1997, and isolated MPV from lesions of active cases. Cases continued to be reported, and a new investigation was initiated by WHO and CDC in October 1997. This report summarizes the results of the field investigation, which indicate that this is the largest human monkeypox outbreak ever recorded.

    This paper describes the current prevalence of tuberculosis and its management in the Democratic People's Republic of Korea. A review of technical reports of NGOs' experience working in North Korea with Democratic People's Republic of Korea officials, tuberculosis healthcare personnel and tuberculosis patients. Site visits, observations and experiences are also included. Until 2001, the Democratic People's Republic of Korea, was predominately isolated with an unknown healthcare system but has since allowed NGOs, WHO and international agencies to rehabilitate the healthcare infrastructure involving 200 people's Country Hospitals, 13 Prophylactic Hospitals, 62 Sanitariums and 4 Special Hospitals. The mid 1990s witnessed a resurgence of tuberculosis in North Korea with 100,000 new cases reported yearly. Preliminary analysis revealed that poverty, neglect, lack of resources and isolation resulted in the overall deterioration of public health services. Present estimates suggest a prevalence of 220 per 100,000 with 45,000 new cases. Tuberculosis is a major public health problem in North Korea that will require increased efforts by the national government and international agencies to control

    We investigated the major trends in health aid financing in the Democratic People's Republic of Korea (DPRK) by identifying the primary donor organizations and examining several data sources to track overall health aid trends. We collected gross disbursements from bilateral donor countries and international organizations toward the DPRK according to specific health sectors by using the Organization for Economic Cooperation and Development creditor reporting system database and the United Nations Office for the Coordination of Humanitarian Affairs financial tracking service database. We analyzed sources of health aid to the DPRK from the Republic of Korea (ROK) using the official records from the ROK's Ministry of Unification. We identified the ROK, United Nations Children's Fund (UNICEF), World Health Organization (WHO), United Nations Population Fund (UNFPA), and The Global Fund to Fight AIDS, Tuberculosis and Malaria (GFATM) as the major donor entities not only according to their level of health aid expenditures but also their growing roles within the health sector of the DPRK. We found that health aid from the ROK is comprised of funding from the Inter-Korean Cooperation Fund, private organizations, local governments, and South Korean branches of international organizations such as WHO and UNICEF. We also distinguished medical equipment aid from developmental aid to show that the majority of health aid from the ROK was developmental aid. This study highlights the valuable role of the ROK in the flow of health aid to the DPRK, especially in light of the DPRK's precarious international status. Although global health aid from many international organizations has decreased, organizations such as GFATM and UNFPA continue to maintain their focus on reproductive health and infectious diseases.

  5. Rapid identification of paragonimiasis foci by lay informants in Lao People's Democratic Republic.

    Directory of Open Access Journals (Sweden)

    Peter Odermatt

    Full Text Available BACKGROUND: Paragonimiasis is a food-borne trematodiasis leading to lung disease. Worldwide, an estimated 21 million people are infected. Foci of ongoing transmission remain often unnoticed. We evaluated a simple questionnaire approach using lay-informants at the village level to identify paragonimiasis foci and suspected paragonimiasis cases. METHODOLOGY/PRINCIPAL FINDINGS: The study was carried out in an endemic area of Lao People's Democratic Republic. Leaders of 49 remote villages in northern Vientiane Province were asked to notify suspected paragonimiasis patients using a four-item questionnaire sent through administrative channels: persons responding positively for having chronic cough (more than 3 weeks and/or blood in sputum with or without fever. We validated the village leaders' reports in ten representative villages with a door-to-door survey. We examined three sputa of suspected patients for the presence of Paragonimus eggs and acid fast bacilli. 91.8% of village leaders participated and notified a total of 220 suspected patients; 76.2% were eventually confirmed; an additional 138 suspected cases were found in the survey. Sensitivity of village leaders' notice for "chronic cough" and "blood in sputum" was 100%; "blood in sputum" alone reached a sensitivity of 85.7%. SIGNIFICANCE: Our approach led to the identification of three previously unknown foci of transmission. A rapid and simple lay-informant questionnaire approach is a promising low-cost community diagnostic tool of paragonimiasis control programs.

    Achievements in cultivating sulfur dioxide resistant conifers in the German Democratic Republic are summarized. These conifers will be planted in afforestation programs in smoke damage zones I, i.e. in conifer forests at high elevations with maximum pollution damage. Nurseries with the most promising tree types have been established for harvesting seeds for propagation. Cultivation of cuttings and tree grafting is carried out in experimental nurseries along with laboratory gas treatment tests. Smoke resistant varieties of the common spruce Picae abies (L.) show vigorous growth in smoke damage zone I. Other spruce types suitable for cultivation are Picea pungens Engelm., Picea omorica (Panc.) Purk. with the highest vitality in 15 to 20 year old trial plantings in smoke damage zone I extreme, and Picea glanca, rubens and orientalis. Suitable pines are Pinus contorta Dougl. ex Loud. (Murray pine), Pinus mugo Turra, and others; resistant larches are Larix decidua and Larix leptolepis. Deciduous trees being cultivated for afforestation are aspens (Populus tremula L.) and mountain ash (Sorbus aucuparia L.). 11 references.

    Diseases caused by mosquito-borne viruses are among the most important emerging diseases that threaten human and animal health, particularly in Africa. However, little attention has been paid to these diseases in the Democratic Republic of the Congo (DRC). The present cross-sectional study was undertaken between March and May 2014 to investigate the presence of mosquito-borne viruses in mosquitoes collected from five municipalities of Kinshasa, DRC. Mosquitoes were collected using BG-Sentinel traps and battery-powered aspirators. Female mosquitoes were pooled according to their genera and sampling locations, preserved in RNAlater, and later screened for viruses using reverse transcription PCR (RT-PCR) assays. A total of 2922 mosquitoes were collected and 29 pools of female mosquitoes, containing approximately 30 mosquitoes each, were tested. Twelve of the 29 (41.4%) mosquito pools were found to be infected with at least one arbovirus, with eight (27.5%) pools positive for Alphavirus, nine (31%) for Flavivirus, and five (17.2%) for Bunyaviridae. Chikungunya, o'nyong'nyong, and Rift valley fever viruses were detected. The present study shows that mosquitoes in Kinshasa carry mosquito-borne viruses that may have serious public health implications. Further investigations on the presence of mosquito-borne viruses in the human and livestock populations of Kinshasa and DRC are recommended. Copyright © 2017 The Author(s).

    A structural study has been undertaken on a cobaltoan dolomite, with chemical formula CaMg0.83Co0.17(CO3)2 (cal-cium magnesium cobalt dicarbonate), from Kolwezi, Democratic Republic of Congo. Pale-pink euhedral cobaltoan dolomite was associated with kolwezite [(Cu1.33Co0.67)(CO3)(OH)2] and cobaltoan malachite [(Cu,Co)2(CO3)(OH)2]. A crystal with a Co:Mg ratio of 1:5.6 (SEM/EDAX measurement), twinned on (11 -2 0) was used for crystal structural refinement. The refinement of the structural model of Reeder & Wenk [Am. Mineral. (1983 ▶), 68, 769-776; Ca at site 3a with site symmetry -3; Mg site at site 3b with site symmetry -3; C at site 6c with site symmetry 3; O at site 18f with site symmetry 1] showed that Co is totally incorporated in the Mg site, with refined occupancy Mg0.83Co0.17, which compares with Mg0.85Co0.15 from chemical data. The Co substitution reflects in the expansion of the cell volume, with a pronounced increasing of the c cell parameter.

    Smallpox eradication is considered to be one of the most remarkable accomplishments of the 20th century. Lessons learned from the campaign during the 1960s and 1970s in the Democratic Republic of Congo (DRC) can provide important information for the development of other eradication programs including polio. The DRC is the third largest country in Africa; the population suffers from extreme poverty, deteriorating infrastructure and health systems, and long periods of civil strife. Despite these challenges, DRC's smallpox eradication campaign was successful, eradicating smallpox only 41 months after initiation. DRC had been polio free since 2001; however, in 2006, imported cases were identified in the country. Polio transmission has since been re-established and DRC now has the second greatest number of reported polio cases in the world. Challenges which existed during the smallpox campaign in DRC are still present today; additionally, the polio vaccine itself poses unique challenges which include requiring multiple doses to confer immunity. In the fight against polio in DRC, it will be important to draw from the smallpox eradication experience. A number of important themes emerged during the campaign that could be beneficial to eradicating polio and future eradication programs that may follow. During the smallpox campaign, a standard vaccination program was implemented, surveillance was intensified, and there were strong collaborative programs with community involvement. These successful elements of the smallpox campaign should be adapted and applied in DRC in polio eradication programs. Copyright © 2011 Elsevier Ltd. All rights reserved.

    2000-03-31

    In 1988, the World Health Assembly resolved to eradicate poliomyelitis by December 31, 2000 (1). Although progress has been extraordinary (2), full implementation of polio eradication strategies has been delayed in several countries affected by war. The Democratic Republic of Congo (DRC) has experienced continual armed conflict since October 1996. As a result, DRC is the last country in the African Region of the World Health Organization (WHO) to implement National Immunization Days (NIDs*). DRC is an important global reservoir for wild poliovirus and shares more than 5580 miles (9000 km) of border with nine countries; in at least seven of these countries polio is endemic. The large area of DRC, substantial amount of poverty, weak health-care infrastructure, poor transportation and communication, and competing demands for resources present considerable challenges to polio eradication. This report summarizes information on the existing health-care infrastructure and routine coverage, information from NIDs carried out in 1999, and results from the recently established surveillance system for acute flaccid paralysis (AFP).

    Analysis of national health insurance accounts in the Democratic Republic of Congo (DRC) clearly shows the importance of international sanitary aid, particularlyfor thefunding ofgeneral referral hospitals, the management of inpatients with AIDS, administration of health zones andfunding of preventive care providers. It The targeted changes described in this article could possibly optimize the efficiency ofinternational aidfor the DRC population, mainly for disorders considered to be a health care priority (i.e. malaria, AIDS, tuberculosis) as well as in the fight against malnutrition. Recommendations target the implementation of procedures for control offood chain security, changes in lifestyle and dietary habits of the population but also comprise extensive restructuring of the health care administration. A dramatic change of the structure in charge of drug distribution as well as eradication of the transfer of part of public health structure income to public health administrative personnel could result in the allocation of significantfunds to thefight against the most important diseases. Better collaboration between the various departments in charge of health care professional training, together with enhanced responsibility of health care personnel is essential. Independent and respected non-governmental organizations should be involved in an audit process, targeting all aspects of the current DRC health system. Eventually, in an equal opportunity perspective, taking into consideration the very high degree of poverty ofDRC inhabitants, implementation of health insurance programmes, use ofgeneric drugs and generalization ofmicro-credit initiatives should also be implemented.

    A diverse group of 103 children aged 7-11 years old living in family and residential care in rural and urban settings in two northern provinces in Lao People's Democratic Republic participated in group discussions using images and community mapping. Children's identified sources of risk and protection illustrate primary public health and protection concerns and resources. Young children worried about lack of hygiene, unintentional injuries, corporal punishment, and domestic violence. They also expressed concern about gambling and children sleeping in the streets, even if they had never seen any of the latter in their communities. In contrast, food and shelter; artistic, religious, and cultural practices; supportive interpersonal relationships; and schooling largely evoked feelings of safety and belonging. Images that prompted conflicting interpretations surfaced individual and contextual considerations that nuanced analysis. Researchers and decision-makers will benefit from using this developmentally appropriate, context-sensitive child-centred visual method to elicit young children's views of risk and protection. It may also serve as a tool for public health education. Involving young children in the initial selection of images would further enhance the efficiency of the method.

    Full Text Available An increased prevalence of epilepsy has been reported in many onchocerciasis endemic areas.To determine the prevalence and distribution of epilepsy in an onchocerciasis endemic region in the Democratic Republic of the Congo (DRC.An epilepsy prevalence study was carried out in 2014, in two localities of the Bas-Uélé district, an onchocerciasis endemic region in the Orientale Province of the DRC. Risk factors for epilepsy were identified using a random effects logistic regression model and the distribution of epilepsy cases was investigated using the Moran's I statistic of spatial auto-correlation.Among the 12,776 individuals of Dingila, 373 (2.9% individuals with epilepsy were identified. In a house-to-house survey in Titule, 68 (2.3% of the 2,908 people who participated in the survey were found to present episodes of epilepsy. Epilepsy showed a marked spatial pattern with clustering of cases occurring within and between adjacent households. Individual risk of epilepsy was found to be associated with living close to the nearest fast flowing river where blackflies (Diptera: Simuliidae-the vector of Onchocerca volvulus-oviposit and breed.The prevalence of epilepsy in villages in the Bas-Uélé district in the DRC was higher than in non-onchocerciasis endemic regions in Africa. Living close to a blackflies infested river was found to be a risk factor for epilepsy.

    Blastocystis sp. is the most common protist found in the intestinal tract of humans and animals. Blastocystis subtypes (STs) are classified based on the molecular phylogeny of the small subunit rRNA gene (SSU rDNA). At least 17 Blastocystis STs have been reported and, of these, STs 1-9 have been found in humans. This study revealed the presence of human Blastocystis STs in Lao People's Democratic Republic (Lao PDR). Fecal samples were collected from apparently healthy people from the central province of Khammouane and the southern province of Champasak. Fresh fecal samples, found to be positive for Blastocystis using microscopy, were individually cultured in Jones' medium and each sample was used for the amplification and sequencing of a fragment of SSU rDNA. BLAST searches and phylogenetic analysis confirmed the distribution of four Blastocystis STs: ST1 (64%), ST2 (8%), ST3 (24%) and ST7 (4%). This is the first report to provide molecular data revealing the prevalence of Blastocystis STs in apparently healthy people from Lao PDR. Copyright © 2017 Elsevier B.V. All rights reserved.

    This study has determined the proportional seropositivity of two zoonotic diseases, Q fever and brucellosis, and bluetongue virus (BTV) which is nonzoonotic, in five provinces of Lao People's Democratic Republic (PDR) (Loungphabang, Luangnumtha, Xayaboury, Xiengkhouang, and Champasak, and Vientiane Province and Vientiane capital). A total of 1,089 samples from buffalo, cattle, pigs, and goats were tested, with seropositivity of BTV (96.7%), Q fever (1.2%), and brucellosis (0.3%). The results of this survey indicated that Q fever seropositivity is not widely distributed in Lao PDR; however, Xayaboury Province had a cluster of seropositive cattle in seven villages in four districts (Botan, Kenthao, Paklaiy, and Phiang) that share a border with Thailand. Further studies are required to determine if Xayaboury Province is indeed an epidemiological hot spot of Q fever activity. There is an urgent need to determine the levels of economic loss and human health-related issues caused by Q fever, brucellosis, and BTV in Lao PDR. PMID:27430548

    Artisans in Masisi and other parts of the North Kivu province in the eastern Democratic Republic of Congo (DRC) mine columbite-tantalite mineral ores (also called 'coltan') for the tantalum content. The potential occupational radiation exposures in the course of this operation, due to the presence of naturally occurring radioactive material (NORM), have been investigated in this screening survey. Activity concentrations of the naturally occurring radionuclides in samples of coltan were measured using gamma-ray spectrometry. The average values in Bq g(-1) are 10.75 +/- 5.11 for (238)U, 7.06 +/- 3.39 for (226)Ra, 1.75 +/- 0.85 for (232)Th, and 1.63 +/- 0.52 for (40)K. Based on these values and the working scenarios involved in artisanal coltan mining, the occupational doses that may accrue from a variety of exposure pathways were determined by model calculations. The results, assuming conservative dust load and dilution factors, indicate that grinding and sieving coltan can give rise to high occupational doses, up to 18 mSv per annum on average.

    2015-01-01

    Technical assistance (TA) is a common component of health system strengthening interventions. This type of intervention is too often designed and evaluated according to a logic that fails to take into account social complexity. Actors' perceptions are one element of this complexity. This article presents a study conducted in the Democratic Republic of Congo designed to identify perceptions concerning two types of technical support providers for health system strengthening: long-term technical assistants (agents of development agencies) and provincial technical advisors (agents of the Ministry of Health). Interviews were conducted with an innovative tool inspired by the principles of systems thinking. Interviewees were actors involved in a TA intervention in the province of Bandundu. Their expectations regarding TA providers were identified in terms of personal characteristics (knowledge, know-how and interpersonal skills), roles, and styles of interaction for capacity building ("interventionist/ prescriptive axes"). Interviewees emphasized the importance of mutual learning and the quality of interactions, which depends on TA provider's interpersonal skills and mutual willingness. Perceptions of TA provider's characteristics tend to be similar, but several differences were observed concerning the expectations about the roles of TAs, and the style that should be adopted for capacity building. Ignoring these differences in expectations may be a threat to the effectiveness of TA.

  18. The EU’s Security Sector Reform Policies in the Democratic Republic of Congo

    Full Text Available In this article we approach the functioning of bureaucracy in ESDP from a governance perspective that also focuses on informal patterns of interaction between the relevant bureaucratic actors. Following the governance and related network governance approaches, the interplay between formal and informal patterns of interaction can help to overcome deadlock in policy-making and to procure effective problem-solving. This perspective is applied to security sector reform (SSR in the Democratic Republic of Congo (DRC. SSR is one of the major emerging fields of activity within the civilian crisis management dimension of ESDP, that also in the DRC became a focal point in the EU’s new security and defence policy since its inception. However, as the EU involvement in the Congolese security sector reform policies illustrates, coordination and negotiation among European actors to overcome deadlock and produce effective problem-solving is not self-evident or even desirable for all actors. In the case of the EU’s SSR policies in Congo, coordination indeed occurs between the actors that are dependent upon each other in terms of resources and have the willingness to jointly tackle the problems related to the SSR in the DRC. However, it is also often undermined by actors that prefer to engage bilaterally because they possess the resources to do so and the personal relationships with the Congolese authorities to act more efficiently and effectively.

    We compared the feeding ecology of the Hali-Hali community of bonobos (Pan paniscus) at Kokolopori, a new field site in the Democratic Republic of the Congo, between two periods 5 months apart. During the first study period (SP1), bonobos relied heavily on the dry seeds of Guibourtia (Caesalpiniaceae), mostly eaten from the ground. The second period (SP2) was characterized by high consumption of ripe tree fruit. Terrestrial herbaceous vegetation (THV) contributed little to the diet in either study period. The low amount of ripe fruit and the high reliance on seeds in the diet during SP1 were associated with high cortisol production and low levels of urinary C-peptide in females, suggesting nutritional stress. However, female gregariousness was not constrained during the fruit-poor period, probably because high seed abundance on the ground ameliorated scramble feeding competition. This is the first description of extensive seed predation by bonobos. It suggests that bonobo feeding ecology may be more similar to that of chimpanzees than previously recognized.

    Full Text Available Abstract Background Malaria is highly endemic in the Democratic Republic of Congo (DRC, but the limits and intensity of transmission within the country are unknown. It is important to discern these patterns as well as the drivers which may underlie them in order for effective prevention measures to be carried out. Methods By applying high-throughput PCR analyses on leftover dried blood spots from the 2007 Demographic and Health Survey (DHS for the DRC, prevalence estimates were generated and ecological drivers of malaria were explored using spatial statistical analyses and multilevel modelling. Results Of the 7,746 respondents, 2268 (29.3% were parasitaemic; prevalence ranged from 0-82% within geographically-defined survey clusters. Regional variation in these rates was mapped using the inverse-distance weighting spatial interpolation technique. Males were more likely to be parasitaemic than older people or females (p Conclusions This research demonstrates the feasibility of using population-based behavioural and molecular surveillance in conjunction with DHS data and geographic methods to study endemic infectious diseases. This study provides the most accurate population-based estimates to date of where illness from malaria occurs in the DRC and what factors contribute to the estimated spatial patterns. This study suggests that spatial information and analyses can enable the DRC government to focus its control efforts against malaria.

    Objective:To determine the seroprevalence of toxoplasmosis in pregnant women, as well as the proportion of acutely infected and risk factors in the Democratic Republic of Congo. Methods:Thirty maternities in Kinshasa were randomly selected and women attending antenatal consultation were invited to participate. They were interviewed with a structured questionnaire about known risk factors (age, meat consumption, contact with soil, and presence of cat) and a venous blood sample was taken. Sera were analysed for total immunoglobulins (Ig) by VIDAS Toxo Competition using Enzyme Linked Fluorescent Assay. IgM was determined by VIDIA Toxo IgM and IgG avidity by VIDAS Toxo IgG avidity. Results: A total of 781 women were included. Median age was 28 years old (IQR: 8.5). And 627 women (80.3%; 95%CI: 77.5-83.1) were found to be positive to total Ig and 17 out of 387 (4.4%;95%CI: 2.3-6.4) were positive to IgM. IgG avidity was low for 2 (11.8%) women, intermediate for 2 (11.8%) and high for 13 women (76.4%). There was no statistically significant association between Toxoplasma gondii infection and any risk factors assessed. Conclusion: In Kinshasa, toxoplasmosis endemicity is highly prevalent. One woman out of twenty five had a recent toxoplasmosis infection and 20%were not protected against primo-infection, indicating a need for measures to prevent and control toxoplasmosis during pregnancy.

    Recent large-scale outbreaks in the Lao People's Democratic Republic (Lao PDR) were reported in 1993 and 1994 and from 2000 to 2002. On December 23, 2007, a drastic increase in acute watery diarrhea patients at a health center in Sekong Province was reported to the provincial health office. An outbreak investigation was initiated to understand the magnitude of the outbreak, identify new cases, identify the suspected causal agent, implement control measures, and prevent new cases. Through active village based surveillance, 370 cases and 3 deaths were reported from 31 villages between December 15, 2007 and January 29, 2008. Of these reported cases, 29% were under the age of 5. From 28 fresh stool samples taken, 17 (58.6%) were positive for Vibrio cholerae O1 Ogawa strain. Two water sources close to affected villages were found to be contaminated with the same strain of V. cholerae. Control measures implemented included health education for safe household water consumption and early identification and treatment of suspected cholera patients at village level. The cause of the outbreak was suspected to be a combination of contaminated drinking water and person-to-person transmission.

    2011-06-01

    We sought to provide data-based estimates of sexual violence in the Democratic Republic of Congo (DRC) and describe risk factors for such violence. We used nationally representative household survey data from 3436 women selected to answer the domestic violence module who took part in the 2007 DRC Demographic and Health Survey along with population estimates to estimate levels of sexual violence. We used multivariate logistic regression to analyze correlates of sexual violence. Approximately 1.69 to 1.80 million women reported having been raped in their lifetime (with 407 397-433 785 women reporting having been raped in the preceding 12 months), and approximately 3.07 to 3.37 million women reported experiencing intimate partner sexual violence. Reports of sexual violence were largely independent of individual-level background factors. However, compared with women in Kinshasa, women in Nord-Kivu were significantly more likely to report all types of sexual violence. Not only is sexual violence more generalized than previously thought, but our findings suggest that future policies and programs should focus on abuse within families and eliminate the acceptance of and impunity surrounding sexual violence nationwide while also maintaining and enhancing efforts to stop militias from perpetrating rape.

    Octavie Lunguya

    Full Text Available BACKGROUND: Drug resistance of Salmonella enterica serovar Typhi (Salmonella Typhi to first-line antibiotics is emerging in Central Africa. Although increased use of fluoroquinolones is associated with spread of resistance, Salmonella Typhi with decreased ciprofloxacin susceptibility (DCS has rarely been reported in Central Africa. METHODOLOGY/PRINCIPAL FINDINGS: As part of a microbiological surveillance study in the Democratic Republic of the Congo (DR Congo, Salmonella Typhi isolates from bloodstream infections were collected prospectively between 2007 and 2011. The genetic relationship of the Salmonella Typhi isolates was assessed by pulsed-field gel electrophoresis (PFGE. The antimicrobial resistance profile of the isolates was determined and mutations associated with DCS were studied. In total, 201 Salmonella Typhi isolates were collected. More than half of the Salmonella Typhi isolates originated from children and young adults aged 5-19. Thirty different PFGE profiles were identified, with 72% of the isolates showing a single profile. Multidrug resistance, DCS and azithromycin resistance were 30.3%, 15.4% and 1.0%, respectively. DCS was associated with point mutations in the gyrA gene at codons 83 and 87. CONCLUSIONS/SIGNIFICANCE: Our study describes the first report of widespread multidrug resistance and DCS among Salmonella Typhi isolates from DR Congo. Our findings highlight the need for increased microbiological diagnosis and surveillance in DR Congo, being a prerequisite for rational use of antimicrobials and the development of standard treatment guidelines.

    Taeniasis and cysticercosis are important but underreported parasitic zoonoses in the Lao People's Democratic Republic (Lao PDR). Reports of human and pig cysticercosis are rather limited and based largely on anecdotal evidence. To date, no structured surveys of disease prevalence or incidence have been reported. However, one unpublished pilot survey of pig cysticercosis in a slaughterhouse in northern Laos estimated prevalence to be 1.7%, without speciation of parasite cysts. Over the past 20 years, nine surveys of intestinal helminthic infection have been conducted; the prevalence of human taeniasis ranged from 0 to 14.0%. The study designs and sample sizes varied greatly, however a high degree of spatial and age variation in taeniasis prevalence was evident. These results are however inconclusive as the species of tapeworm infecting the people was not determined. To further our knowledge of taeniasis and cysticercosis in Lao PDR, structured community-based surveys in high-risk areas are required in combination with the use of sensitive and specific diagnostic tests capable of identifying the pork tapeworm, Taenia solium. This will enable the development and implementation of control measures that are both appropriate and sustainable if T. solium is shown to be a public health threat.

    Caprine tuberculosis is a major health problem for goats and a major zoonosis of veterinary public health interest. In order to prepare a response to and control of caprine tuberculosis, to evaluate the potential risks to public health, and to assess the prevalence of the disease in Katanga province, Democratic Republic of Congo, 656 goats that were slaughtered at the Kabasele abattoir of Mzee Laurent-Desire Kabila Market in Lubumbashi were subjected to rigorous veterinary inspection during June to August 2012. All goat specimens came from the Kasumbalesa, Kasenga, and Kipushi areas of Katanga province. Consequently, suspected organs presenting signs of tuberculosis were collected and examined using Ziehl-Neelsen stains for diagnosis. Through this investigative inspection in the province, we found an overall prevalence of caprine tuberculosis of 1.68%. Although females showed higher prevalence of caprine tuberculosis (1.07%) compared to males (0.61%), and adults showed higher prevalence (1.22%) than juveniles (0.45%), these comparisons were not statically significant. However, lung and intestine infection by tuberculosis showed significantly higher prevalence of positive cases (1.21 and 0.46%, respectively) (p tuberculosis (1.22%) compared to goats from Kipushi (0.31%) and Kasenga (0.18%). These findings show the risk of caprine tuberculosis in the province for the first time, and we therefore recommend the implementation of strict animal biosecurity and tuberculosis controlling protocols.

    Introduction Despite accelerated measles control efforts, a massive measles resurgence occurred in the Democratic Republic of the Congo (DRC) starting in mid-2010, prompting an investigation into likely causes. Methods We conducted a descriptive epidemiological analysis using measles immunization and surveillance data to understand the causes of the measles resurgence and to develop recommendations for elimination efforts in DRC. Results During 2004-2012, performance indicator targets for case-based surveillance and routine measles vaccination were not met. Estimated coverage with the routine first dose of measles-containing vaccine (MCV1) increased from 57% to 73%. Phased supplementary immunization activities (SIAs) were conducted starting in 2002, in some cases with sub-optimal coverage (≤95%). In 2010, SIAs in five of 11 provinces were not implemented as planned, resulting in a prolonged interval between SIAs, and a missed birth cohort in one province. During July 1, 2010-December 30, 2012, high measles attack rates (>100 cases per 100,000 population) occurred in provinces that had estimated MCV1 coverage lower than the national estimate and did not implement planned 2010 SIAs. The majority of confirmed case-patients were aged measles virus strains that were previously identified in the region. Conclusion The resurgence was likely caused by an accumulation of unvaccinated, measles-susceptible children due to low MCV1 coverage and suboptimal SIA implementation. To achieve the regional goal of measles elimination by 2020, efforts are needed in DRC to improve case-based surveillance and increase two-dose measles vaccination coverage through routine services and SIAs.

    On April 23, 2016, the Democratic Republic of the Congo's (DRC's) Ministry of Health declared a yellow fever outbreak. As of May 24, 2016, approximately 90% of suspected yellow fever cases (n = 459) and deaths (45) were reported in a single province, Kongo Central Province, that borders Angola, where a large yellow fever outbreak had begun in December 2015. Two yellow fever mass vaccination campaigns were conducted in Kongo Central Province during May 25-June 7, 2016 and August 17-28, 2016. In June 2016, the DRC Ministry of Health requested assistance from CDC to control the outbreak. As of August 18, 2016, a total of 410 suspected yellow fever cases and 42 deaths were reported in Kongo Central Province. Thirty seven of the 393 specimens tested in the laboratory were confirmed as positive for yellow fever virus (local outbreak threshold is one laboratory-confirmed case of yellow fever). Although not well-documented for this outbreak, malaria, viral hepatitis, and typhoid fever are common differential diagnoses among suspected yellow fever cases in this region. Other possible diagnoses include Zika, West Nile, or dengue viruses; however, no laboratory-confirmed cases of these viruses were reported. Thirty five of the 37 cases of yellow fever were imported from Angola. Two-thirds of confirmed cases occurred in persons who crossed the DRC-Angola border at one market city on the DRC side, where ≤40,000 travelers cross the border each week on market day. Strategies to improve coordination between health surveillance and cross-border trade activities at land borders and to enhance laboratory and case-based surveillance and health border screening capacity are needed to prevent and control future yellow fever outbreaks.

    Full Text Available Background: Contraception is often necessary in order to plan for children and without it there is a risk of unplanned pregnancies. In the Democratic Republic of Congo, this often results in abortions by untrained persons with resultant morbidity and mortality. Aim: To investigate the factors that influence contraceptive use amongst women of childbearing age in the Vanga health zone. Methods: Cross-sectional survey using interviewer-administered questionnaires. Results: Of the 384 women recruited, a majority (46.1% were in the 31–40 year age group;52% had reached primary school and 88% did not have formal employment. One hundredand forty of the participants reported current use of contraception, with 60% of them using modern methods of contraception; 36.1% of them had begun using contraception before the age of 20; and the most common methods were oral contraceptive pills and injection, each accounting for 22.9%. There was variation in the duration of contraceptive use and the main reason for using contraception was to space children. Of the participants, 20.7% had been using contraception for more than two years. Seventy-seven (31.5% of the women reported they did not use contraception because of a fear of side effects. Forty-four (18% reported that they are unable to afford contraception, 38 (15.6% had husbands who disapproved of contraceptive usage, 26 (10.6% had a fear of infertility, 18 (7.4% practised a religion that did not allow them to use contraception and 12 of the women (4.9% did not use contraception because it was unavailable to them. Conclusion: Barriers to contraception in our study were fears of side effects and infertility, cost, male partner’s objection, unavailability of contraception and religious beliefs.

    Anemia is a severe public health problem in the Lao People's Democratic Republic (PDR). Consequently, a new control strategy to reduce the burden of anemia has been introduced for preschool children (aged 6-52 months). The objective of this study was to assess the current prevalence of anemia and related factors in preschool children in southern rural Lao PDR. A population-based cross-sectional study was carried out in six communities in Songkhone district, Savannakheth province, in February 2009. As a result, the prevalence of anemia was found to be 48.9% (95% confidence interval (CI), 43.5-54.3), although most cases were mild. A multiple logistic regression analysis indicated that there was no protective effect of breastfeeding against anemia. The anemia prevalence was higher in 1) children aged 6-23 months (Odds Ratio (OR) = 1.73, 95% CI, 1.02-2.90) than in older children, 2) children in large families (6 or more members) (OR = 1.96, 95% CI, 1.17-3.29), and 3) children in three remote villages with relatively difficult access to markets (OR = 3.01, 95% CI, 1.25-7.47).In Lao PDR, improvement of food practices and home-fortified food supplementation interventions are essential. High-risk groups should be targeted and a long-term health education program that aims to modify food habits implemented. Furthermore, in settings where iron deficiency is not the only cause of anemia, combining an iron supplement with other measures is necessary.

    Bovine-associated zoonotic infectious diseases pose a significant threat to human health in the Lao People's Democratic Republic (Lao PDR). In all, 905 cattle and buffalo serum samples collected in northern Lao PDR in 2006 were used to determine seroprevalence of five major bovine zoonotic infectious diseases that included Taenia saginata cysticercosis, bovine tuberculosis, Q-fever, bovine brucellosis, and bovine leptospirosis. Five enzyme-linked immunosorbent assays (ELISAs) were used to test for the presence of antibodies to the diseases, except Taenia saginata, for which we tested for the presence of Taenia metacestode circulating antigens. The overall highest prevalence was for T. saginata (46.4%), with lower prevalence for Q-fever (4%), leptospirosis (3%), tuberculosis (1%), and brucellosis (0.2%). Although there were no significant differences in the proportion of seroprevalence between sex and age of the animals sampled, there were significant differences between the provincial distributions. Further studies are required to determine the seroprevalence of these infections in other locations in Lao PDR, as well as other animal species including humans, in order to develop effective prevention and control strategies. This is the first study to investigate the prevalence of bovine zoonotic infectious agents in the Lao PDR. Positivity was demonstrated for all diseases investigated, with the highest prevalence for T. saginata antigen and Coxiella burnetti antibodies. For T. saginata, there were significant differences in the provincial distribution. Approximately 16% seroprevalence of Coxiella burnetti was noted in Xayabuly Province; however, there are no clear reasons why this was the case, and further studies are required to determine risk factors associated with this observation.

    To evaluate onchocerciasis control activities in the Democratic Republic of Congo (DRC) in the first 12 years of community-directed treatment with ivermectin (CDTI). Data from the National Programme for Onchocerciasis (NPO) provided by the National Onchocerciasis Task Force (NOTF) through the annual reports of the 21 CDTI projects for the years 2001-2012 were reviewed retrospectively. A hypothetical-inputs-process-outputs-outcomes table was constructed. Community-directed treatment with ivermectin expanded from 1968 communities in 2001 to 39 100 communities by 2012 while the number of community-directed distributors (CDD) and health workers (HW) multiplied. By 2012, there were ratios of 1 CDD per 262 persons and 1 HW per 2318 persons at risk. More than 80% of the funding came from the fiduciary funds of the African Programme for Onchocerciasis Control. The cost of treatment per person treated fell from US$ 1.1 in 2001 to US$ 0.1 in 2012. The therapeutic coverage increased from 2.7% (2001) to 74.2% (2012); the geographical coverage, from 4.7% (2001) to 93.9% (2012). Geographical coverage fell in 2005 due to deaths in loiasis co-endemic areas, and the therapeutic coverage fell in 2008 due to insecurity. Challenges to CDTI in DRC have been serious adverse reactions to ivermectin in loiasis co-endemic areas and political conflict. Targets for personnel or therapeutic and geographical coverages were not met. Longer term funding and renewed efforts are required to achieve control and elimination of onchocerciasis in DRC. © 2014 John Wiley & Sons Ltd.

    Full Text Available BACKGROUND: The epidemic of gender-based violence in the Democratic Republic of the Congo (DRC has garnered popular media attention, but is incompletely described in the medical literature to date. In particular, the relative importance of militarized compared to civilian rape and the impact on vulnerable populations merits further study. We describe a retrospective case series of sexual abuse among children and youth in eastern DRC. METHODS: Medical records of patients treated for sexual assault at HEAL Africa Hospital, Goma, DRC between 2006 and 2008 were reviewed. Information extracted from the chart record was summarized using descriptive statistics, with comparative statistics to examine differences between pediatric (≤ 18 yrs and adult patients. FINDINGS: 440 pediatric and 54 adult sexual abuse cases were identified. Children and youth were more often assaulted by someone known to the family (74% vs 30%, OR 6.7 [95%CI 3.6-12], p72 hours after the assault was more common in pediatric patients (53% vs 33%, OR 2.2 [95%CI 1.2-4.0], p = 0.007. Physical signs of sexual abuse, including lesions of the posterior fourchette, hymeneal tears, and anal lesions, were more commonly observed in children and youth (84% vs 69%, OR 2.3 [95%CI 1.3-4.4], p = 0.006. Nine (2.9% pediatrics patients were HIV-positive at presentation, compared to 5.3% of adults (p = 0.34. INTERPRETATION: World media attention has focused on violent rape as a weapon of war in the DRC. Our data highlight some neglected but important and distinct aspects of the ongoing epidemic of sexual violence: sexual abuse of children and youth.

    Full Text Available BACKGROUND: Retaining patients with HIV infection in care is still a major challenge in sub- Saharan Africa, particularly in the Democratic Republic of Congo (DRC where the antiretroviral treatment (ART coverage is low. Monitoring retention is an important tool for evaluating the quality of care. METHODS AND FINDINGS: A review of medical records of HIV-infected children was performed in three health facilities in the DRC: the Amo-Congo Health center, the Monkole Clinic in Kinshasa, and the HEAL Africa Clinic in Goma. Medical records of 720 children were included. Kaplan Meier curves were constructed with the probability of retention at 6 months, 1 year, 2 years and 3 years. Retention rates were: 88.2% (95% CI: 85.1%-90.8% at 6 months; 85% (95% CI: 81.5%-87.6% at one year; 79.4% (95%CI: 75.5%-82.8% at two years and 74.7% (95% CI: 70.5%-78.5% at 3 years. The retention varied across study sites: 88.2%, 66.6% and 92.5% at 6 months; 84%, 59% and 90% at 12 months and 75.7%, 56.3% and 85.8% at 24 months respectively for Amo-Congo/Kasavubu, Monkole facility and HEAL Africa. After multivariable Cox regression four variables remained independently associated with attrition: study site, CD4 cell count <350 cells/µL, children younger than 2 years and children whose caregivers were member of an independent church. CONCLUSIONS: Attrition remains a challenge for pediatric HIV positive patients in ART programs in DRC. In addition, the low coverage of pediatric treatment exacerbates the situation of pediatric HIV/AIDS.

    Background In regions where access to clean water and the provision of a sanitary infrastructure has not been sustainable, cholera continues to pose an important public health burden. Although oral cholera vaccines (OCV) are effective means to complement classical cholera control efforts, still relatively little is known about their acceptability in targeted communities. Clarification of vaccine acceptability prior to the introduction of a new vaccine provides important information for future policy and planning. Methods In a cross-sectional study in Katanga province, Democratic Republic of Congo (DRC), local perceptions of cholera and anticipated acceptance of an OCV were investigated. A random sample of 360 unaffected adults from a rural town and a remote fishing island was interviewed in 2010. In-depth interviews with a purposive sample of key informants and focus-group discussions provided contextual information. Socio-cultural determinants of anticipated OCV acceptance were assessed with logistic regression. Results Most respondents perceived contaminated water (63%) and food (61%) as main causes of cholera. Vaccines (28%), health education (18%) and the provision of clean water (15%) were considered the most effective measures of cholera control. Anticipated vaccine acceptance reached 97% if an OCV would be provided for free. Cholera-specific knowledge of hygiene and self-help in form of praying for healing were positively associated with anticipated OCV acceptance if costs of USD 5 were assumed. Conversely, respondents who feared negative social implications of cholera were less likely to anticipate acceptance of OCVs. These fears were especially prominent among respondents who generated their income through fishing. With an increase of assumed costs to USD 10.5, fear of financial constraints was negatively associated with anticipated vaccine acceptance as well. Conclusions Results suggest a high motivation to use an OCV as long as it seems affordable. The

    Three groups of metrics of spatial patterns of forest cover loss were calculated for the Democratic Republic of Congo (DRC). While other studies had previously assessed landscape patterns in the Congo Basin, they had done so for small areas due to data limitations. The input data for this study, the Forets d;Afrique Central Evaluee par Teledetection(FACET), allowed the analysis to be performed at the national level. FACET is a landsat-scale dataset giving an unprecedented synoptic view of forest cover and forest cover loss for the DRC for three time periods: 2000, 2005 and 2010. The three groups of metrics evaluated the following spatial characteristics of forest cover loss for the same standard 1.5km unit of area: proportions of typologies of forest lost, forest fragmentation and proximity of forest loss patches from other land cover types. Results indicate that there are several different typologies of forest cover loss in the DRC, and offer quantitative explanations of these differences, providing a valuable locally-relevant tool for land use planning, available at the national level. Spatial patterns of forest cover loss highlight differences between areas of high primary forest loss due to agriculture conversion in frontier deforestation, such as in the east of the country, areas of equivalent primary and secondary forest loss emanating from the rural complex and areas of variable proportions of primary and secondary forest loss but important ecological repercussions of forest fragmentation due to isolated, but systematic forest perforations. Typologies of spatial patterns of forest cover loss are presented as well as their correlated drivers, and ecological, conservation and land use planning considerations are discussed.

  20. Helminth and intestinal protozoa infections, multiparasitism and risk factors in Champasack province, Lao People's Democratic Republic.

    Full Text Available BACKGROUND: Detailed investigations of multiparasitism are scarce in the Mekong River basin. We assessed helminth (trematode, nematode, and cestode, and intestinal protozoa infections, and multiparasitism in random population samples from three different eco-epidemiological settings in Champasack province, southern Lao People's Democratic Republic (Lao PDR, and determined underlying risk factors. METHODOLOGY: Two stool samples were collected from 669 individuals aged ≥ 6 months over consecutive days and examined for helminth infections using the Kato-Katz method. Additionally, one stool sample per person was subjected to a formalin-ethyl acetate concentration technique for diagnosis of helminth and intestinal protozoa infections. Questionnaires were administered to obtain individual and household-level data pertaining to behavior, demography and socioeconomic status. Risk factors for hepato-biliary and intestinal parasitic infections and multiparasitism were determined using multiple logistic regressions analyses. PRINCIPAL FINDINGS: MULTIPLE SPECIES INTESTINAL PARASITE INFECTIONS WERE COMMON: 86.6% of the study participants harbored at least two and up to seven different parasites concurrently. Regarding nematode infections, hookworm was the most prevalent species (76.8%, followed by Ascaris lumbricoides (31.7% and Trichuris trichiura (25.0%. Regarding trematodes, Opisthorchis viverrini and Schistosoma mekongi infections were found in 64.3% and 24.2% of the participants, respectively. Infections with intestinal protozoa were rare. CONCLUSIONS/SIGNIFICANCE: There is a pressing need to intensify and sustain helminth control interventions in the southern part of Lao PDR. Given the high prevalence with nematode and trematode infections and the extent of multiparasitism, preventive chemotherapy is warranted. This intervention should be coupled with health education and improved access to clean water and adequate sanitation to consolidate morbidity

    In many African countries, first referral hospitals received little attention from development agencies until recently. We report the evolution of two of them in an unstable region like Eastern Democratic Republic of Congo when receiving the support from development aid program. Specifically, we aimed at studying how actors' network and institutional framework evolved over time and what could matter the most when looking at their performance in such an environment. We performed two cases studies between 2006 and 2010. We used multiple sources of data: reports to document events; health information system for hospital services production, and "key-informants" interviews to interpret the relation between interventions and services production. Our analysis was inspired from complex adaptive system theory. It started from the analysis of events implementation, to explore interaction process between the main agents in each hospital, and the consequence it could have on hospital health services production. This led to the development of new theoretical propositions. Two events implemented in the frame of the development aid program were identified by most of the key-informants interviewed as having the greatest impact on hospital performance: the development of a hospital plan and the performance based financing. They resulted in contrasting interaction process between the main agents between the two hospitals. Two groups of services production were reviewed: consultation at outpatient department and admissions, and surgery. The evolution of both groups of services production were different between both hospitals. By studying two first referral hospitals through the lens of a Complex Adaptive System, their performance in a context of development aid takes a different meaning. Success is not only measured through increased hospital production but through meaningful process of hospital agents'" network adaptation. Expected process is not necessarily a change; strengthened

    Understanding how malaria parasites move between populations is important, particularly given the potential for malaria to be reintroduced into areas where it was previously eliminated. We examine the distribution of malaria genetics across seven sites within the Democratic Republic of Congo (DRC) and two nearby countries, Ghana and Kenya, in order to understand how the relatedness of malaria parasites varies across space, and whether there are barriers to the flow of malaria parasites within the DRC or across borders. Parasite DNA was retrieved from dried blood spots from 7 Demographic and Health Survey sample clusters in the DRC. Malaria genetic characteristics of parasites from Ghana and Kenya were also obtained. For each of 9 geographic sites (7 DRC, 1 Ghana and 1 Kenya), a pair-wise RST statistic was calculated, indicating the genetic distance between malaria parasites found in those locations. Mapping genetics across the spatial extent of the study area indicates a complex genetic landscape, where relatedness between two proximal sites may be relatively high (RST > 0.64) or low (RST < 0.05), and where distal sites also exhibit both high and low genetic similarity. Mantel's tests suggest that malaria genetics differ as geographic distances increase. Principal Coordinate Analysis suggests that genetically related samples are not co-located. Barrier analysis reveals no significant barriers to gene flow between locations. Malaria genetics in the DRC have a complex and fragmented landscape. Limited exchange of genes across space is reflected in greater genetic distance between malaria parasites isolated at greater geographic distances. There is, however, evidence for close genetic ties between distally located sample locations, indicating that movement of malaria parasites and flow of genes is being driven by factors other than distance decay. This research demonstrates the contributions that spatial disease ecology and landscape genetics can make to

    Monitoring tropical forest carbon stocks changes has been a rising topic in the recent years as a result of REDD+ mechanisms negotiations. Such monitoring will be mandatory for each project/country willing to benefit from these financial incentives in the future. Aerial and satellite remote sensing technologies offer cost advantages in implementing large scale forest inventories. Despite the recent progress made in the use of airborne LiDAR for carbon stocks estimation, no widely operational and cost effective method has yet been delivered for central Africa forest monitoring. Within the Maï Ndombe region of Democratic Republic of Congo, the EO4REDD project develops a method combining satellite, aerial and ground measurements. This combination is done in three steps: [1] mapping and quantifying forest cover changes using an object-based semi-automatic change detection (deforestation and forest degradation) methodology based on very high resolution satellite imagery (RapidEye), [2] developing an allometric linear model for above ground biomass measurements based on dendrometric parameters (tree crown areas and heights) extracted from airborne stereoscopic image pairs and calibrated using ground measurements of individual trees on a data set of 18 one hectare plots and [3] relating these two products to assess carbon stocks changes at a regional scale. Given the high accuracies obtained in [1] (> 80% for deforestation and 77% for forest degradation) and the suitable, but still to be improved with a larger calibrating sample, model (R² of 0.7) obtained in [2], EO4REDD products can be seen as a valid and replicable option for carbon stocks monitoring in tropical forests. Further improvements are planned to strengthen the cost effectiveness value and the REDD+ suitability in the second phase of EO4REDD. This second phase will include [A] specific model developments per forest type; [B] measurements of afforestation, reforestation and natural regeneration processes and

    Full Text Available Rabies is one of the major public health problems mostly affecting developing countries in Africa and Asia where 99.9% of all rabies related human deaths are recorded each year. In Democratic Republic of Congo, repeated outbreaks have been reported. Despite this, there is little reliable epidemiological data about rabies in the country for the development of effective control strategies.A retrospective study was carried out in Kinshasa Province during a period of five years (2009-2013 to describe the proportion of rabid animals and the species involved in rabies transmission and maintenance. The survey also aimed at describing the spatial-temporal distribution of rabies. To gather information, the daily registers of institutions involved in rabies diagnosis were reviewed and each rabies case was traced back to area of occurrence for collection of geographic coordinates.A total of 5,053 attacks were registered involving six animal species including dog, cat, monkey, rabbit, rat, and pig. Based on clinical observations, rabies was reported in dogs and cats while data obtained from the laboratory confirmed rabies cases included dogs, cats and a goat. The annual distribution showed a significant decrease of rabies cases from 2009 up to 2011 and a later increase up to 2013. There was no difference in rabies occurrence between seasons (p = 0.721. Rabies cases were three times higher in peri-urban zone than in urban zone OR = 3.4 (95% CI: 2.3-5.1. The positive proportion of rabies was 2.6% (95% CI: 2.1-3 based on clinical evidence and 65.9% (95% CI: 50-79.5 for laboratory confirmed cases.This study confirms the endemicity of rabies in Kinshasa where occurrence of rabies cases was related to human population density and lifestyle. In order to control rabies, there is need to set up a surveillance program and implement efficient mass vaccination campaigns of susceptible animals.

    Full Text Available To determine the prevalence and the species spectrum of intestinal parasites (IP involved in hospitalized AIDS patients, a prospective observational and cross-sectional study was carried out in the four main hospitals in Kinshasa, Democratic Republic of the Congo. From November 2006 through September 2007, a single stool sample was collected from 175 hospitalized AIDS patients older than 15 years. Parasites were detected by light microscopy, including Ziehl-Neelsen, Fungi-Fluor, modified trichrome stains, and by immunofluorescence antibody tests and PCR for species diagnosis of microsporidia. At baseline, 19 patients (10.8 % were under antiretroviral therapy and 156 (89.2 % were eligible for ART. The main diagnosis for justifying hospitalization was intestinal infection associated with diarrhea in 87 out of 175 (49.7 %. 47 out of 175 (26.9 % were found to harbor an IP, and 27 out of 175 (15.4 % were infected with at least one opportunistic IP (OIP. Prevalence rate for OIP were 9.7 %, 5.1 %, 1.7 % and 0.6 % for Cryptosporidium sp., Enterocytozoon bieneusi, Isospora belli and Encephalitozoon intestinalis respectively. Considering patients with diarrhea only, prevalence rate were 12.6 %, 4.6 %, 3.4 % and 1.1 % respectively. The other IP observed were Entamoeba histolytica/Entamoeba dispar in nine cases (5.1 %, Ascaris lumbricoïdes in seven cases (4.0 %, Giardia intestinalis in three cases (1.7 %, hookworm in two cases (1.1 % and Trichiuris trichiura, Enterobius vermicularis, Schistosoma mansoni in one patient each (0.6 %. No significant relationship was established between any individual IP and diarrhea. These results underline the importance of OIP in symptomatic AIDS patients regardless of diarrhea at the time of the hospitalisation, and showed that routine microscopic examination using stains designed for Cryptosporidium spp. or the microsporidia should be considered due to the absence of clinical markers.

    The bonobo (Pan paniscus), a great ape that is endemic to the Democratic Republic of the Congo (DRC), has been listed as Endangered on the IUCN Red List since 2007. Hunting and habitat loss are primary threats. Two recent wars and ongoing conflicts in the DRC have resulted in political and economic instability that hampers on-the-ground work, thereby accentuating the importance of spatial data and maps as tools for monitoring threats remotely and prioritizing locations for safeguarding bonobo habitat. Several regional and rangewide efforts have leveraged the utility of existing spatial data to help focus limited resources for effective broad-scale conservation of these great apes. At local scales, we developed spatial models to identify locations of highest hunting pressure, predict future human settlement and agricultural expansion, map areas of highest conservation value to bonobos, and identify the connective corridors linking them. We identified 42 least-disturbed wildland blocks meeting the minimum home range size needed for bonobos, and 32 potential corridors. At the range-wide scale, we developed a first range-wide spatial model of suitable conditions for the bonobo; this was a major contribution to the development of a Bonobo Conservation Strategy for 2012-2022, recently published by IUCN. The model used a forest edge density metric and other biotic and abiotic variables in conjunction with bonobo nest data collected during 2003-2010 by over 40 bonobo researchers. Approximately 28% of the range was predicted suitable; of that, about 27.5% was located in official protected areas. Highlighting these examples, this presentation will discuss the conservation status of bonobos and how spatial data and models are being utilized for the formation of strategic conservation plans.

    Full Text Available Assessment and management of volcanic risk are important scientific, economic, and political issues, especially in densely populated areas threatened by volcanoes. The Virunga area in the Democratic Republic of Congo, with over 1 million inhabitants, has to cope permanently with the threat posed by the active Nyamulagira and Nyiragongo volcanoes. During the past century, Nyamulagira erupted at intervals of 1–4 years – mostly in the form of lava flows – at least 30 times. Its summit and flank eruptions lasted for periods of a few days up to more than two years, and produced lava flows sometimes reaching distances of over 20 km from the volcano, thereby affecting very large areas and having a serious impact on the region of Virunga. In order to identify a useful tool for lava flow hazard assessment at the Goma Volcano Observatory (GVO, we tested VORIS 2.0.1 (Felpeto et al., 2007, a freely available software (http://www.gvb-csic.es based on a probabilistic model that considers topography as the main parameter controlling lava flow propagation. We tested different Digital Elevation Models (DEM – SRTM1, SRTM3, and ASTER GDEM – to analyze the sensibility of the input parameters of VORIS 2.0.1 in simulation of recent historical lava-flow for which the pre-eruption topography is known. The results obtained show that VORIS 2.0.1 is a quick, easy-to-use tool for simulating lava-flow eruptions and replicates to a high degree of accuracy the eruptions tested. In practice, these results will be used by GVO to calibrate VORIS model for lava flow path forecasting during new eruptions, hence contributing to a better volcanic crisis management.

    Among the common soil-transmitted helminth infections, hookworm causes the highest burden. Previous research in the southern part of Lao People's Democratic Republic (Lao PDR) revealed high prevalence rates of hookworm infection. The purpose of this study was to predict the spatial distribution of hookworm infection and intensity, and to investigate risk factors in the Champasack province, southern Lao PDR. A cross-sectional parasitological and questionnaire survey was conducted in 51 villages. Data on demography, socioeconomic status, water, sanitation, and behavior were combined with remotely sensed environmental data. Bayesian mixed effects logistic and negative binomial models were utilized to investigate risk factors and spatial distribution of hookworm infection and intensity, and to make predictions for non-surveyed locations. A total of 3,371 individuals were examined with duplicate Kato-Katz thick smears and revealed a hookworm prevalence of 48.8%. Most infections (91.7%) were of light intensity (1-1,999 eggs/g of stool). Lower hookworm infection levels were associated with higher socioeconomic status. The lowest infection levels were found in preschool-aged children. Overall, females were at lower risk of infection, but women aged 50 years and above harbored the heaviest hookworm infection intensities. Hookworm was widespread in Champasack province with little evidence for spatial clustering. Infection risk was somewhat lower in the lowlands, mostly along the western bank of the Mekong River, while infection intensity was homogeneous across the Champasack province. Hookworm transmission seems to occur within, rather than between villages in Champasack province. We present spatial risk maps of hookworm infection and intensity, which suggest that control efforts should be intensified in the Champasack province, particularly in mountainous areas.

    Recent studies have shown that fragmentation is an increasing threat to global forests, which has major impacts on biodiversity and the important ecosystem services provided by forested landscapes. Several tools have been developed to evaluate global patterns of fragmentation, which have potential applications for REDD+. We study how canopy height and above ground biomass (AGB) change across several categories of forest edges determined by fragmentation analysis. We use Democratic Republic of Congo (DRC) as an example. An analysis of variance of different edge widths and airborne estimated canopy height found that canopy heights were significantly different in forest edges at a distance of 100 m from the nonforest edge. Biomass was significantly different between fragmentation classes at an edge distance of 300 m. Core forest types were found to have significantly higher canopy height and greater AGB than forest edges and patches, where height and biomass decrease significantly as the level of fragmentation increases. A change analysis shows that deforestation and degradation are increasing over time and biomass loss associated with degradation account for at least one quarter of total loss. We estimate that about 80 % of primary forests are intact, which decreases 3.5 % over the 15 year study period, as primary forest is either deforested or transitioned to forest edge. While the carbon loss per hectare is lower than that of deforestation, degradation potentially affects up to three times more area than deforestation alone. When defining forest degradation by decreased biomass without any loss in forest area, assessing transitions of core forest to edges over time can contribute an important element to REDD+MRV systems. The estimation of changes between different forest fragmentation types and their associated biomass loss can provide an estimate of degradation carbon emission factors. Forest degradation and emissions due to fragmentation are often

    Full Text Available Starting from the socio-political context of changes that have affected the education systems of Eastern European countries, the authors summarize the specific nature of the process of democratization of education in Europe at the turn of the century. The paper analyzes the purpose of democratization of education and of introduction of Civic Education and Religious Education classes in the education system of the Republic of Serbia, observing the idea that education may serve as a generator of social changes, and stating that school is an important support pillar in promoting and accepting the values of the community, as well as in personal growth and the development of every individual. The presented theoretical concepts are supported by the summary of results of empirical studies that have been focused on the analysis of the pedagogical aspects of the implementation of teaching these subjects at the secondary level of education from the perspective of teachers, pupils and parents. Based on the insight into the topic, the authors suggest searching for a “common tangent” in Civic Education and Religious Education teaching process via an open and tolerant dialogue of participants of both subjects, which would enable the exchange of experiences, attitudes, and opinions of pupils, as well as coinciding and permeating of spiritual and democratic values as a foundation for further democratization of school in general.

    2016-12-23

    In the Democratic Republic of the Congo (DRC), the Ministry of Health authorizes only physicians and nurses to give injections, with one exception-medical and nursing students may also give injections if supervised by a clinical instructor. The emergence of the injectable contraceptive Sayana Press in some African countries prompted the DRC to test the acceptability and feasibility of distributing Sayana Press and other contraceptive methods at the community level through medical and nursing students. Sayana Press is similar in formulation to the injectable contraceptive Depo-Provera but contains a lower dose and is administered subcutaneously using a single-use syringe with a short needle called the Uniject system. The Uniject system allows Sayana Press to be administered by community health workers without clinical training or by self-injection. In this pilot, the advocacy objective was to obtain approval from the Ministry of Health to allow medical and nursing students to inject Sayana Press, as a first step toward authorization for community health workers to provide the method. The pilot described in this article documents a process whereby an innovative approach moved from concept to implementation to replication in less than 2 years. It also paved the way for testing additional progressive strategies to increase access to contraception at the community level. Because the pilot project included a research component designed to assess benefits and challenges, it provided the means to introduce the new task-shifting approach, which might not have been approved otherwise. Key pilot activities included: (1) increasing awareness of Sayana Press among family planning stakeholders at a national conference on family planning, (2) enlisting the support of key decision makers in designing the pilot, (3) obtaining marketing authorization to distribute Sayana Press in the DRC, (4) implementing the pilot from July to December 2015, (5) conducting quantitative and

    Full Text Available The African region represents the weak point of the world economy. Many African countries have still not finished the process of transforming their economy. Agriculture represents only a minor portion of their economies’ performance – however it is still a key sector of the economy (especially considering the number of people working in agriculture or people representing the agricultural population. The agricultural sector in many sub-Saharan countries is extremely sensitive and its stability affects the stability of the whole region. A very good example representing sub-Saharan Africa is the Democratic Republic of Congo (DRC. It is a country with a lot of potential, but it is classified among the poorest countries in the world. Its economy is extremely weak (despite its significant share in total GDP formation value, and underdeveloped. The share of agriculture in total GDP formation is over 42.5%. The number of people living in rural areas represents over 45 million out of a total of 75 million. The number of people working in agriculture is over 60% of the total economically active population. The economy of the country is extremely poor and fragile, mainly because of political instability. The aim of this paper is firstly to specify the position of agriculture in the DRC economy, and also to specify the production and trade commodity structure in relation to other African countries. The paper’s ambition is to identify the most perspective commodities (groups of commodities, both for production and also for trade, and to recommend such a production and trade profile which would allow the DRC the possibility of improving its competitiveness - not only in relation to other African countries, but also in relation to the global market. The production and trade commodity structures are analysed through the application of the BCG method and competitiveness analysis. In relation to these objectives, the paper provides the following conclusions

This study reports the findings of an EQA of malaria microscopy in the Democratic Republic of the Congo (DRC. Methods After validation, an EQA slide panel and a questionnaire were delivered to diagnostic laboratories in four provinces of DRC. The panel included three samples for diagnosis (sample 1: Plasmodium falciparum, 177,000/μl, sample 2: P. falciparum, 2,500/μl, sample 3: no parasites seen, one didactic sample (Howell-Jolly bodies and one sample for assessing the quality of staining. Participating laboratories were addressed and selected through the network of the National Tuberculosis Control Programme. Participants were asked to return the responses together with a stained thin and thick blood film for evaluation of Giemsa stain quality. Results Among 174 participants (response rate 95.1%, 26.2% scored samples 1, 2 and 3 correctly and 34.3%, 21.5% and 5.8% of participants reported major errors in one, two or three samples respectively.

    The Democratic Republic of Congo (DRC) is one of the two most leading contributors to the global burden of disease due to malaria. This paper describes the malaria testing and treatment market in the nation's capital province of Kinshasa, including availability of malaria testing and treatment and relative anti-malarial market share for the public and private sector. A malaria medicine outlet survey was conducted in Kinshasa province in 2013. Stratified multi-staged sampling was used to select areas for the survey. Within sampled areas, all outlets with the potential to sell or distribute anti-malarials in the public and private sector were screened for eligibility. Among outlets with anti-malarials or malaria rapid diagnostic tests (RDT) in stock, a full audit of all available products was conducted. Information collected included product information (e.g. active ingredients, brand name), amount reportedly distributed to patients in the past week, and retail price. In total, 3364 outlets were screened for inclusion across Kinshasa and 1118 outlets were eligible for the study. Among all screened outlets in the private sector only about one in ten (12.1%) were stocking quality-assured Artemisinin-based Combination Therapy (ACT) medicines. Among all screened public sector facilities, 24.5% had both confirmatory testing and quality-assured ACT available, and 20.2% had sulfadoxine-pyrimethamine (SP) available for intermittent preventive therapy during pregnancy (IPTp). The private sector distributed the majority of anti-malarials in Kinshasa (96.7%), typically through drug stores (89.1% of the total anti-malarial market). Non-artemisinin therapies were the most commonly distributed anti-malarial (50.1% of the total market), followed by non quality-assured ACT medicines (38.5%). The median price of an adult quality-assured ACT was $6.59, and more expensive than non quality-assured ACT ($3.71) and SP ($0.44). Confirmatory testing was largely not available in the private

    According to the WHO records of 2013, the incidence of poliomyelitis was reduced by more than 99%, the number of endemic countries decreased from 125 in 1988 to 3 in 2013 and over 10 million cases were prevented from poliomyelitis thanks to the intensive use of Oral polio vaccine (OPV). However, the emergence of circulating vaccine-derived poliovirus strains (cVDPV), causing serious epidemics like the wild poliovirus, is a major challenge on the final straight towards the goal of eradication and OPV cessation. This paper describes the cVDPVoutbreak that occurred in the Democratic Republic of Congo (DRC) from November 2011 to April 2012. All children under 15 years of age with acute flaccid paralysis (AFP) and confirmed presence of cVDPV in the stool samples were included. Thirty (30) children, all from the administrative territories of Bukama and Malemba Nkulu in the Katanga Province (south-east DRC), were reported. The virus responsible was the cVDPV type 2 (0.7% -3.5% divergent from the reference Sabin 2 strain) in 29 children (97%) and the ambiguous vaccine-derived poliovirus strain (0.7% divergent) was confirmed in one case (3%), a boy seventeen months old and already vaccinated four times with OPV. Twentyfive children (83%) were protected by any of the routine EPI vaccines and 3 children (10%) had never received any dose of OPV. In reaction, DRC has conducted five local campaigns over a period of 10 months (from January to October 2012) and the epidemic was stopped after the second round performed in March 2012. As elsewhere in similar conditions, low immunization coverage, poor sanitation conditions and the stop of the use of OPV2 have favoured the emergence of the third cVDPV epidemic in DRC. The implementation of the Strategic Plan for Polio eradication and endgame strategic plan 2013-2018 will prevent the emergence of cVDPV and set up the conditions for a coordinated OPV phase out.

    Full Text Available BACKGROUND: Epidemiologic data on malaria are scant in many high-burden countries including the Democratic Republic of the Congo (DRC, which suffers the second-highest global burden of malaria. Malaria control efforts in regions with challenging infrastructure require reproducible and efficient surveillance. We employed new high-throughput molecular testing to characterize the state of malaria control in the DRC and estimate childhood mortality attributable to excess malaria transmission. METHODS AND FINDINGS: The Demographic and Health Survey was a cross-sectional, population-based cluster household survey of adults aged 15-59 years in 2007 employing structured questionnaires and dried blood spot collection. Parasitemia was detected by real-time PCR, and survey responses measured adoption of malaria control measures and under-5 health indices. The response rate was 99% at the household level, and 8,886 households were surveyed in 300 clusters; from 8,838 respondents molecular results were available. The overall prevalence of parasitemia was 33.5% (95% confidence interval [C.I.] 32-34.9; P. falciparum was the most prevalent species, either as monoinfection (90.4%; 95% C.I. 88.8-92.1 or combined with P. malariae (4.9%; 95% C.I. 3.7-5.9 or P. ovale (0.6%; 95% C.I. 0.1-0.9. Only 7.7% (95% CI 6.8-8.6 of households with children under 5 owned an insecticide-treated bednet (ITN, and only 6.8% (95% CI 6.1-7.5 of under-fives slept under an ITN the preceding night. The overall under-5 mortality rate was 147 deaths per 1,000 live births (95% C.I. 141-153 and between clusters was associated with increased P. falciparum prevalence; based on the population attributable fraction, 26,488 yearly under-5 deaths were attributable to excess malaria transmission. CONCLUSIONS: Adult P. falciparum prevalence is substantial in the DRC and is associated with under-5 mortality. Molecular testing offers a new, generalizable, and efficient approach to characterizing

    The Democratic Republic of Congo (DRC) has suffered from war and lingering conflicts in East DRC and has one of the highest infant mortality rates in the world. Prior research has documented increases in infant and child mortality associated with war, but the empirical evidence is limited in several respects. Measures of conflict are quite crude or conflict is not tightly linked to periods of exposure to infant death. Few studies have distinguished between the effects of war on neonatal versus post-neonatal infants. No study has considered possible differences between women who give birth during wartime and those who do not that may be related to greater infant mortality. The analysis used the nationally representative sample of 15,103 mothers and 53,768 children from the 2007 and 2013/2014 Demographic Health Survey in the DRC and indicators of conflict events and conflict deaths from the 2013 Uppsala Conflict Data. To account for unobserved heterogeneity across women, a multi-level modeling approach was followed by grouping all births for each woman and estimating random intercepts in discrete time event history models. Post-neonatal mortality increased during the Congolese wars, and was highest where conflict events and deaths were extreme. Neonatal mortality was not associated with conflict levels. Infant mortality was not higher in East DRC, where conflicts continued during the post Congolese war period. Models specifying unobserved differences between mothers who give birth during war and those who have children in peacetime did not reduce the estimated effect of war, i.e., no support was found for selectivity in the sample of births during war. Differences in effects of the Congolese war on neonatal versus post-neonatal mortality suggest that conflict influences the conditions of infants' lives more than the aspects of mothers' pregnancy conditions and delivery that are relevant for infant mortality. These differences may, however, be specific to the nature

    The prevalence and identity of Rickettsia and Bartonella in urban rat and flea populations were evaluated in Kisangani, Democratic Republic of the Congo (DRC) by molecular tools. An overall prevalence of 17% Bartonella species and 13% Rickettsia typhi, the agent of murine typhus, was found in the cosmopolitan rat species, Rattus rattus and Rattus norvegicus that were infested by a majority of Xenopsylla cheopis fleas. Bartonella queenslandensis, Bartonella elizabethae, and three Bartonella genotypes were identified by sequencing in rat specimens, mostly in R. rattus. Rickettsia typhi was detected in 72% of X. cheopis pools, the main vector and reservoir of this zoonotic pathogen. Co-infections were observed in rodents, suggesting a common mammalian host shared by R. typhi and Bartonella spp. Thus, both infections are endemic in DRC and the medical staffs need to be aware knowing the high prevalence of impoverished populations or immunocompromised inhabitants in this area.

    2013-02-01

    Full Text Available Choreography-based programming is a powerful paradigm for defining communication-based systems from a global viewpoint. A choreography can be checked against multiparty protocol specifications, given as behavioural types, that may be instantiated indefinitely at runtime. Each protocol instance is started with a synchronisation among the involved peers. We analyse a simple transformation from a choreography with a possibly unbounded number of protocol instantiations to a choreography instantiating a single protocol, which is the merge of the original ones. This gives an effective methodology for obtaining new protocols by composing existing ones. Moreover, by removing all synchronisations required for starting protocol instances, our transformation reduces the number of communications and resources needed to execute a choreography.

  8. A Qualitative Analysis of Disclosure Patterns among Women with Sexual Violence-Related Pregnancies in Eastern Democratic Republic of Congo

    Onyango, Monica Adhiambo

    2016-01-01

    The Democratic Republic of the Congo (DRC) has experienced nearly two decades of civil conflict in the Eastern regions of North and South Kivu. This conflict has been notorious for the use of sexual violence as a weapon of war, leading in many cases to pregnancy after rape. The objectives of this analysis were: 1) to describe patterns of sexual violence-related pregnancy (SVRP) disclosure; 2) to consider why survivors chose to disclose to particular individuals; and 3) to examine the dialogue around SVRPs between women with SVRPs and their confidants. In South Kivu Province, Democratic Republic of Congo, two sub-groups of sexual violence survivors completed qualitative interviews, those currently raising a child from an SVRP (parenting group, N = 38) and those who had terminated an SVRP (termination group, N = 17). The findings show that a majority of SVRPs were conceived when participants were held in sexual captivity for prolonged periods of time. The SVRPs were disclosed to friends, family members, other sexual violence survivors, community members, spouses, health care providers, or perpetrators. The confidants were most often chosen because they were perceived by the participants as being discreet, trusted, and supportive. The confidants often provided advice about continuing or terminating the SVRP. Trust and discretion are the most important factors determining to whom women with SVRPs disclose their pregnancies. The vital role of confidants in giving support after disclosure cannot be overlooked. Providing opportunities for survivors to safely disclose their SVRPs, including to health care providers, is a necessary first step in allowing them to access safe and comprehensive post-assault care and services.

    We propose a multiparty quantum cryptographic protocol. Unitary operators applied by Bob and Charlie, on their respective qubits of a tripartite entangled state encoding a classical symbol that can be decoded at Alice's end with the help of a decoding matrix. Eve's presence can be detected by the disturbance of the decoding matrix. Our protocol is secure against intercept-resend attacks. Furthermore, it is efficient and deterministic in the sense that two classical bits can be transferred per entangled pair of qubits. It is worth mentioning that in this protocol, the same symbol can be used for key distribution and Eve's detection that enhances the effciency of the protocol.

  20. High heterogeneity in Plasmodium falciparum risk illustrates the need for detailed mapping to guide resource allocation: a new malaria risk map of the Lao People's Democratic Republic

    2010-02-01

    Full Text Available Abstract Background Accurate information on the geographical distribution of malaria is important for efficient resource allocation. The Lao People's Democratic Republic has experienced a major decline in malaria morbidity and mortality in the past decade. However, efforts to respond effectively to these changes have been impeded by lack of detailed data on malaria distribution. In 2008, a countrywide survey on Plasmodium falciparum diagnosed in health centres and villages was initiated to develop a detailed P. falciparum risk map with the aim to identify priority areas for malaria control, estimate population at risk, and guide resource allocation in the Lao People's Democratic Republic. Methods P. falciparum incidence data were collected from point-referenced villages and health centres for the period 2006-2008 during a country-wide survey between December 2008 and January 2009. Using the highest recorded annual rate, continuous surfaces of P. falciparum incidence were produced by the inverse distance weighted interpolation technique. Results Incidence rates were obtained from 3,876 villages and 685 health centres. The risk map shows that P. falciparum is highly heterogeneous in the northern and central regions of the country with large areas of no transmission. In the southern part, transmission is pervasive and the risk of P. falciparum is high. It was estimated that 3.4 million people (60% of the population live at risk of malaria. Conclusions This paper presents the first comprehensive malaria risk map of the Lao People's Democratic Republic based entirely on empirical data. The estimated population at risk is substantially lower than previous estimates, reflecting the presence of vast areas with focal or no malaria transmission as identified in this study. These findings provide important guidance for malaria control interventions in the Lao People's Democratic Republic, and underline the need for detailed data on malaria to accurately

  2. Heterogenite vs asbolane: a mineralogical study of cobalt oxides from the DRC (Democratic Republic of the Congo)

    Burlet, Christian; Vanbrabant, Yves; Decree, Sophie

    2014-05-01

    The largest cobalt ore reserves are located in DRC, the Democratic Republic of Congo. Most of cobalt is observed as black cobaltic oxide minerals: heterogenite [HCoO2] and asbolane [(Ni,Co)2-xMn(O,OH)4.nH2O] which are hardly differentiable since they exhibit similar macroscopic habit and textures. These minerals are frequently observed in similar environment (oxidized horizon of ore deposits) and they are commonly poorly-crystallized limiting their study with XRD. Their chemical composition is also not very well-constrained since they exhibit significant chemical substitutions with cations as Cu, Co, Ni, Mn. Our observations on a set of heterogenite and asbolane samples from DRC combined with samples from other localities shows that each phase, even under an amorphous form, can be readily distinguished by Raman microspectrometry. This technique is therefore attractive during ore deposit characterization campaigns or during the follow-up extraction operations where it is important to distinguish the main constituting Co-phase(s). The main advantage of this technique is its speed since no sample preparation is required during the collection Raman spectra that usually last few tens of seconds. The method provides information at a μm-scale and several points are thus required to fully characterize ore batches composed of different mineralogical phases. Our petrographical observations show also that asbolane and heterogenite mineralogical phases can coexist at a μm-scale as two distinct phases into 'heterogenite' ore. The distinction between heterogenite and asbolane from our sample set can also be conducted on a chemical base showing that heterogenite represents the richer Co-phase with variable Cu concentrations. By contrast, only Mn traces are usually observed in heterogenite minerals from DRC except in few samples, but always in lower concentration than in asbolane. The latter shows variable Mn/(Mn+Co) ratio between 0.85 and 0.3 and the decrease of this value is

    This paper is about the recognition and interpretation of multiparty meetings captured as audio, video and other signals. This is a challenging task since the meetings consist of spontaneous and conversational interactions between a number of participants: it is a multimodal, multiparty, multistream problem. We discuss the capture and annotation of the Augmented Multiparty Interaction (AMI) meeting corpus, the development of a meeting speech recognition system, and systems for the automatic segmentation, summarization and social processing of meetings, together with some example applications based on these systems.

  4. Incoercible multiparty computation

    Canetti, R.; Gennaro, R. [Massachusetts Institute of Technology, Cambridge, MA (United States)

    1996-12-31

    Current secure multiparty protocols have the following deficiency. The public transcript of the communication can be used as an involuntary commitment of the parties to their inputs and outputs. Thus parties can be later coerced by some authority to reveal their private data. Previous work that has pointed this interesting problem out contained only partial treatment. In this work we present the first general treatment of the coercion problem in secure computation. First we present a general definition of protocols that provide resilience to coercion. Our definition constitutes a natural extension of the general paradigm used for defining secure multiparty protocols. Next we show that if trapdoor permutations exist then any function can be incoercibly computed (i.e., computed by a protocol that provides resilience to coercion) in the presence of computationally bounded adversaries and only public communication channels. This holds as long as less than half the parties are coerced (or corrupted). In particular, ours are the first incoercible protocols without physical security assumptions. Also, our protocols constitute an alternative solution to the recently solved adaptive security problem. Our techniques are quite surprising and include non-standard use of deniable encryptions.

  5. [On the history of the German Democratic Republic Journal Psychiatry, Neurology and Medical Psychology (1949-1990)].

    Teitge, M; Kumbier, E

    2015-05-01

    Scientific journals were established in the Soviet occupied zone following WWII in order to distinguish themselves from the other occupying powers. Starting in 1949 a journal with the title "Psychiatry, Neurology and Medical Psychology" was founded as no publishing house existed in the field of psychiatry and neurology and it became necessary to establish a new journal that was competitive. The journal was primarily distributed in the German Democratic Republic (GDR) until 1990 but the interest internationally was very limited. State affairs had a great influence from the very beginning so that the political involvement was reflected in the selection of staff, such as the publishers and the head of the editorial department and by the close interconnection between the Society for Psychiatry and Neurology of the GDR and the editorship of the journal. The publishers who were primarily responsible and the authors were at the interface of politics and science. Nevertheless, in an international comparison many parallels can be found in the orientation with respect to the content.

    2015-02-01

    Full Text Available Purpose and problem: Human capital represents an investment in education and skills. However, in the Democratic Republic of Congo (DRC the ability of small-scale retailers to grow and increase firm performance is restricted by the scarcity of education and prior work experience.Methodology: Survey data were collected from 126 owner-managers in the retail industry in Kinshasa, DRC, in order to investigate the proposed relationship between the human capital components of education, work experience and venture performance.Findings: Several variables pertaining to education and prior work experience were related to different aspects of venture performance, allowing for support of the hypotheses. Nonetheless, when clustering was conducted some surprising results were observed in that owner-managers tended to have little work experience even where their venture was performing well.Implications: Research into human capital and links to performance in Africa and emerging markets is valuable as recent research has found that the matching of entrepreneurial human capital with opportunities for growth is the essence of economic development.

    2013-01-01

    Full Text Available Abstract In terms of scientific activities generally and ethnobiological pursuits in particular, North Korea, officially known as the Democratic People’s Republic of Korea, is an almost blank entity on the quilt of global research. During a sabbatical semester at Pyongyang University of Science and Technology the author used this opportunity to gather some information on the uses of insect and other terrestrial arthropods as human food and components of traditional healing methods in that country. Despite the widely publicised shortcomings in the supply of food stuffs to the population of North Korea, insects are not generally seen as a source of food worthy of exploitation. However, the therapeutic use of insects, centipedes and scorpions to treat illnesses as diverse as the common cold, skin rashes, constipation, dysentery, nervous prostration, whooping cough, osteomyelitis, tetanus, and various forms of cancer is apparently still popular. The arthropods used therapeutically are credited with anti-inflammatory, immunological and other health-promoting effects, because they are said to contain hormones, steroids, lipids and plant-derived alkaloids, all of which capable of exerting their effects on the human body.

    2013-04-01

    Full Text Available We report the rediscovery of the Pied Butterfly Bat, Glauconycteris superba Hayman, 1939, 40 years after this species was last recorded. The new specimen from Mbiye Island, Democratic Republic of the Congo, is compared with the type specimens of G. s. superba and G. superba sheila Hayman, 1947 and a specimen from Matonguiné, Ivory Coast. The variation in the striking colouration of the pelage as well as in morphometric data is considered to be individual rather than geographic variation and we tentatively regard G. s. sheila as a synonym of the nominate form. Despite the wide distribution of this species in the tropical forest zone of West and Central Africa, only four specimens from four localities are known to date, which might indicate very specific habitat preferences. Contemporary land cover information around historic collection sites shows degraded landscapes. Given the highly uncertain area of occupancy of this species, we suggest changing the status of G. superba in the IUCN Red List of Threatened Species from “Least Concern” to “Data Deficient”.

    The increasing intensification of pork production in southeast Asia necessitates an urgent requirement to better understand the dual impact of pig-associated zoonotic disease on both pig production and human health in the region. Sharing porous borders with five countries and representing many regional ethnicities and agricultural practices, the Lao People's Democratic Republic (Lao PDR) appears well placed to gauge the levels of pig-associated zoonoses circulating in the wider region. Despite this, little is known about the true impact of zoonotic pathogens such as leptospirosis, Trichinella, hepatitis E virus (HEV), Japanese encephalitis (JE), and Taenia solium on human health and livestock production in the country. A comprehensive review of the published prevalences of these five pig-associated zoonoses in Lao PDR has demonstrated that although suspicion remains high of their existence in pig reservoirs across the country, epidemiological data are scarce; only 31 epidemiological studies have been undertaken on these diseases in the past 25 years. A greater understanding of the zoonoses prevalence and subsequent risks associated with pork production in the southeast Asian region could help focus public health and food safety interventions at key points along the value chain, benefiting both livestock producers and the broader animal and human health systems in the region.

    2011-04-01

    Since 1996, the Democratic Republic of Congo (DRC) has been the theatre of armed conflict. More than 5.4 millions have died and 500,000 to 1,000,000 women have been raped. As a result of permanent insecurity including frequent massacres, burning of villages and plundering of personal property and crops, millions of Congolese people especially in eastern regions have been displaced with around 1.3 million in internal refugee camps. Rural populations have abandoned farming that was the main source of employment, food, and income. The purpose of this paper is to describe the socioeconomic impact of this armed conflict particularly on the health of women and children. Consequences include i) decreased food production, ii) worsening food insecurity and malnutrition, iii) reduced household income, and iv) inadequate health care leading to epidemic outbreaks of diseases such as cholera, measles, and meningitis. Food insecurity and poverty affect around 70% of the population. Chronic malnutrition and growth retardation affect 38% of children. The mortality rate for children under 5 has reached 205 per 1000 live births. Other than achieving lasting peace that is a prerequisite for development in the DRC, the main priority must be to provide victims with multiform assistance aimed at restarting the economy and ensuring food self-sufficiency, thereby reducing both malnutrition and child mortality. Better access to healthcare and to psychosocial, medical, and legal services is also needed for rape victims.

    To describe components of a physical therapy pilot program for women with gynecologic fistula, and to report prospective data from the first 2 years of program implementation. A single-cohort observational study with repeated measures was conducted at HEAL Africa Hospital, Goma, Democratic Republic of Congo. Hospital staff received training in pelvic floor physical therapy. Guidelines for exercise, functional training, and reproductive health education were integrated into the existing program. Demographics, clinical findings, and functional outcomes were recorded. Key stakeholders were interviewed to understand the perceived strengths and limitations of the program. A total of 205 women were followed up; 161 participated in physical therapy, with an average of 9.45 sessions. Of 161 women examined postoperatively, 102 (63.4%) reported no incontinence; they remained continent at discharge. Of 21 who indicated a change in level of incontinence during postoperative physical therapy, 15 (71.4%) improved. The program was feasible and well received by staff and patients. Pelvic floor physical therapy could have significant results in women with gynecologic fistula, may be an important adjunctive treatment in comprehensive fistula care, and warrants further investigation.

    We conducted a systematic review of the scientific literature between 1996 and 2013 on rape in war-ridden Eastern Democratic Republic of Congo (DRC) in order to better understand the interest of the scientific community in describing the magnitude and characteristics of the problem. The literature search was conducted in French and English using several databases (Pubmed, PsycInfo, Sapphire, BDSP, Embase, Rero, and Web of Science) with the key words "rape and DRC" combined with several Medical Subject Headings concepts. Our systematic review yielded 2,087 references, among which only 27 are original studies, that is 20 are based on population surveys and the remaining 7 are original data based on case studies and reviews. Ten studies provided prevalence rates of rape victims, 18 provided specific information on the profile of the victims, 10 reported that most of the perpetrators of rape were military personnel, 14 referred to the negligence of the government in protecting victims, and 10 reported a lack of competent health-care facilities. The awareness of rape in conflict-ridden DRC is still limited as reported in the scientific literature: Published scientific papers are scarce. Yet more research would probably help mobilize local authorities and the international community against this basic human rights violation.

For 41 of the 70 (58.6%) strains, the same subtype/ CRF designations were observed in pol and env. Twenty-three (32.9%) of 70 pol sequences were complex recombinants involving two to five subtypes as well as fragments that could not be classified into any of the known subtypes. All subtypes were involved in recombination events. Unclassified (U) and env subtype H strains were very likely to be recombinant strains. Overall, many minor mutations were identified in the protease sequences. Although at the time of our study ARV use was not yet widespread in DRC, three strains were identified with one major mutation associated with drug resistance: L90M and M46L in protease and K103N in RT.

    Full Text Available The Congo Basin forests are a prime location for implementing REDD+. National REDD+ policy processes are ongoing and many REDD+ pilot initiatives are being demonstrated. However, the level of national engagement, progress and distribution of REDD+ activities varies considerably in the different Congo Basin countries. This study therefore uses a set of criteria to assess national and international policy initiatives and approaches for advancing REDD+ implementation in Cameroon and the Democratic Republic Congo (DRC, two countries where more than two thirds of the Congo Basin forests are concentrated. Our findings show that (i both countries have shown the highest political presence at the international climate negotiations but DRC has invested more in the size of its delegation and side events; (ii REDD+ donors, initiatives, and funding are disproportionately skewed towards DRC making it technically more advanced; (iii the high political interest and institutional reforms in DRC favors private sector investments in REDD+ programs; and (iv the REDD+ policy process is internally-driven in Cameroon with a strong national ownership, while it is externally-driven in DRC with weak national ownership. To advance REDD+, the government of DRC should embark on capacity building programs that ensure the transfer of REDD+ technical know-how from international to national actors while Cameroon needs to speed-up governance reforms and be more flexible in order to attract influential international REDD+ actors. This paper further provides specific recommendations.

    In the Democratic Republic of Congo (DRC), a country in a post-conflict period, high priority cannot be given to non-communicable diseases other than to emergencies. This certainly involves inadequacy in raising awareness for prevention of these diseases. To evaluate the level of knowledge of the Congolese general population on hypertension and diabetes mellitus. Responses to a questionnaire from 3% of the general population aged 15 and older in the city of Bukavu and two rural areas: Hombo and Walungu (South Kivu, eastern DRC), recruited after stratification by ward in the city of Bukavu and a group of prone villages were expected. The questions focused on identification, testing, causes, complications and treatment of hypertension and diabetes mellitus. Of the 7770 respondents, screening for hypertension and diabetes mellitus affected only 14.9% and 7.3% of subjects respectively. Knowledge of these two conditions was generally low in the general population, although better in the subgroups of patients and those with higher socioeconomic level (Pknowledge (Pknowledge about hypertension and diabetes mellitus and their testing in South Kivu is low. It is imperative that the Congolese government includes non-communicable diseases in its priorities of the millennium. Similarly, the WHO should actively contribute to screening for them in low-income countries. Copyright © 2012 Elsevier Masson SAS. All rights reserved.

    Childhood lead exposure remains a problem in developing countries, and little is known about its effects on early child neurodevelopment and temperament in the Democratic Republic of Congo (DRC). We, therefore, conducted this study to determine the association between lead exposure and the neurodevelopment and behaviour of children aged 12-24 months in Kinshasa, DRC. A cross-sectional study was conducted between February and June 2012, and parents of 104 children were invited to participate. Blood lead levels (BLLs) of each child were tested using the flame atomic spectrophotometry method. All children were subject to a clinical examination and assessed with two selected early child neurodevelopmental tools, the Gensini-Gavito and the baby characteristics questionnaire, to measure their neurodevelopment and temperament. Detectable BLLs ranged from 1 to 30 μg/dl with a geometric mean of 6.9 (SD 4.8) μg/dl. BLLs at 5-9 and ≥10 μg/dl were significantly associated with the child temperament (p lead were reported with more temperament difficulties at even blood lead levels lead exposure among children in Kinshasa, DRC.

    Soil-transmitted helminth (STH) infections, and schistosomiasis and other trematodiases often have a high prevalence in developing countries. Here, we present updated information on the prevalence of these parasites in the Lao People's Democratic Republic (Lao PDR) in 2012, arising from the annual national helminthiasis survey. Fecal specimens were collected from 8,610 inhabitants of 12 provinces and one municipality (Bokeo, Houaphan, Luang Namtha, Luang Prabang, Oudomxay, and Phongsaly Provinces from northern Lao PDR; Bolikhamxay and Xieng Khouang Provinces and Vientiane Municipality from the central part of the country; and Attapeu, Champasak, Saravan, and Sekong Provinces from southern Lao PDR). The overall prevalence of three major STHs, Ascaris lumbricoides, Trichuris trichiura, and hookworms (Necator americanus and Ancylostoma duodenale) were 11.6%, 8.5%, and 25.0%, respectively. Prevalence of Schistosoma mekongi infection was 0.1%, and of miscellaneous trematodiases (including opisthorchiasis) was 14.0%. Clearly, the nationwide parasite control project is still necessary to reduce morbidity caused by helminthic diseases.

    Ancylostoma (A.) ceylanicum, one of the most common species of hookworms infecting dogs and cats, also causes patent infections in humans and is now considered to be the second most common hookworm species infecting populations in southeast Asia. A Japanese patient who returned from a visit to Thailand and Lao People's Democratic Republic (PDR) was presented with intermittent watery diarrhea with eosinophilia. Hookworm eggs were found in feces samples, and adult worms were confirmed to be present in the jejunum with capsule endoscopy and double balloon enteroscopy. A diagnosis of A. ceylanicum infection was made based on the morphology of the adult worms along with findings of a PCR-based molecular study using larvae obtained from a fecal sample culture. The infection was considered likely to have been obtained during a 1-month stay in a Laotian village, where the patient had eaten local food, worn sandals on bare feet, and lived as a local native villager, though he had stayed in modern hotels during the visit to Thailand.

    Recent agreements between the Democratic People's Republic of Korea (DPRK) and the other countries involved in the six-party talks on the future of the DPRK's nuclear weapons program have focused attention on the North Korean energy sector, and, specifically, what the international community can or should do to assist the DPRK in energy sector redevelopment. During two visits to North Korea in 1998 and 2000, a team of American and North Korean researchers conducted a unique rural energy use survey in a flood-affected rural village in the DPRK-the farming village of Unhari. The information gathered during the survey has important implications on how to properly approach the ongoing rural energy crisis in the DPRK, and, more broadly, to provide overall energy sector assistance. The results of the Unhari survey are described briefly, followed by suggestions of internal policy and legal reforms, approaches to international cooperation, key and attractive energy sector technologies and processes for energy sector redevelopment in the DPRK.

    This paper presents a thorough description of Nyamulagira's January 2010 volcanic eruption (North Kivu, Democratic Republic of Congo), based on a combination of field observation and ground-based and space-borne data. It is the first eruption in the Virunga Volcanic Province that has been described by a combination of several modern monitoring techniques. The 2010 eruption lasted 26 days and emitted ˜45.5 × 106 m3 of lava. Field observations divided the event into four eruptive stages delimited by major changes in effusive activity. These stages are consistent with those described by Pouclet (1976) for historical eruptions of Nyamulagira. Co-eruptive signals from ground deformation, seismicity, SO2 emission and thermal flux correlate with the eruptive stages. Unambiguous pre-eruptive ground deformation was observed 3 weeks before the lava outburst, coinciding with a small but clear increase in the short period seismicity and SO2 emission. The 3 weeks of precursors contrasts with the only precursory signal previously recognized in the Virunga Volcanic Province, the short-term increase of tremor and long period seismicity, which, for example, were only detected less than 2 h prior to the 2010 eruption. The present paper is the most detailed picture of a typical flank eruption of this volcano. It provides valuable tools for re-examining former—mostly qualitative—descriptions of historical Nyamulagira eruptions that occurred during the colonial period.

    Sexual violence survivors who decide to report their assault interact with health care, law enforcement, and legal and judicial professionals. Professionals' attitudes about sexual violence and survivors play an important role in caring for survivors and in the pursuit of justice. Despite evidence showing the relationship between service provider beliefs and survivor outcomes, relatively little is known about professionals' beliefs about sexual violence or their attitudes toward sexual violence survivors. Between June 2012 and December 2014, our study examined the beliefs and attitudes of 181 professionals from the health care, legal, and law enforcement sectors in the Eastern Democratic Republic of the Congo (DRC) and the Rift Valley region of Kenya, areas with a high prevalence of sexual violence. To determine correlates of beliefs and attitudes about sexual violence and sexual violence survivors, multiple logistic regression models were adjusted for demographic and occupational characteristics. Respondents who agreed that survivors got what they deserved (7%) or that survivors should feel ashamed (9%) were the minority, while those who would be willing to care for a family member with a history of sexual violence (94%) were the majority. Profession was significantly associated with beliefs and attitudes about sexual violence and survivors. Law enforcement professionals were more likely than health professionals and lawyers to indicate that survivors should feel ashamed. Our findings suggest a need for interventions that adequately address potentially harmful beliefs and attitudes of some professionals serving sexual violence survivors.

    To understand perspectives of local health providers on the social reintegration of patients who have undergone fistula repair in the eastern Democratic Republic of Congo. In a qualitative study, semi-structured individual interviews were conducted with patient-care professionals working with women with fistula at HEAL Africa Hospital (Goma) and Panzi Hospital (Bukavu) between June and August 2011. The interviews were transcribed and themes elicited through manual coding. Overall, 41 interviews were conducted. Successful surgical repair was reported to be the most important factor contributing to patients' ability to lead a normal life by all providers. Family acceptance-especially from the husband-was deemed crucial for reintegration by 39 (95%) providers, and 29 (71%) believed this acceptance was more important than the ability to work. Forty (98%) providers felt that, on the basis of African values, future childbearing was key for family acceptance. Because of poor access and the high cost of cesarean deliveries, 28 (68%) providers were concerned about fistula recurrence. Providers view postsurgical childbearing as crucial for social reintegration after fistula repair. However, cesarean deliveries are costly and often inaccessible. More work is needed to improve reproductive health access for women after fistula repair. Copyright © 2015 International Federation of Gynecology and Obstetrics. Published by Elsevier Ireland Ltd.

    Implementation of mass drug administration for lymphatic filariasis (LF) has been delayed in central Africa because of incomplete mapping and coendemic loiasis. We mapped two regions in eastern Democratic Republic of Congo that were suspected to have LF. Night blood samples were collected from 2,724 subjects in 30 villages. Filarial antigenemia rates by card test exceeded 1% in 28 villages (range = 0-14%). Prevalence rates for large sheathed microfilariae (Mf) ranged from 4% to 40%; Mansonella perstans rates ranged from 22% to 98%. Large Mf were exclusively Loa loa by microscopy, and only 1 of 337 samples tested by quantitative polymerase chain reaction (qPCR) was positive for Wuchereria bancrofti DNA. Filarial antigen positivity was strongly associated with high L. loa Mf counts. Periodicity studies revealed atypical patterns, with no significant diurnal periodicity in some individuals. Thus, methods routinely used for LF mapping may not be reliable in areas in central Africa that are highly endemic for loiasis. © The American Society of Tropical Medicine and Hygiene.

    In the Democratic Republic of the Congo (DRC), artesunate-amodiaquine is first-line therapy for falciparum malaria; little is known about the prevalence of molecular markers of parasite drug resistance. Across the DRC, we genotyped 166 parasites in Plasmodium falciparum chloroquine resistance transporter (pfcrt) using polymerase chain reaction (PCR) and sequencing. Of these parasites, 73 (44%) parasites were pure wild-type CVMNK, 55 (31%) parasites were chloroquine-resistant CVIET: , 35 (21.1%) parasites were mixed CVMNK and CVIET: , and 3 parasites were other genotypes. Ninety-two infections (55.4%) harbored the pfcrt K76T: substitution that is highly correlated with chloroquine failure. The amodiaquine-resistant S: VMNT: haplotype was absent. Geographically, pfcrt haplotypes were not clearly clustered. Chloroquine accounted for 19.4% of antimalarial use, and amodiaquine accounted for 15.3% of antimalarial use; there were no associations between drug use and mutant haplotype prevalence. In the DRC, our molecular survey indicates that resistance to chloroquine is substantial but that resistance to amodiaquine is absent. These contrasting findings highlight the need for molecular surveillance of drug resistance to inform malaria control policies.

    Paektu volcano (Changbaishan) is a rhyolitic caldera that straddles the border between the Democratic People's Republic of Korea and China. Its most recent large eruption was the Millennium Eruption (ME; 23 km(3) dense rock equivalent) circa 946 CE, which resulted in the release of copious magmatic volatiles (H2O, CO2, sulfur, and halogens). Accurate quantification of volatile yield and composition is critical in assessing volcanogenic climate impacts but is challenging, particularly for events before the satellite era. We use a geochemical technique to quantify volatile composition and upper bounds to yields for the ME by examining trends in incompatible trace and volatile element concentrations in crystal-hosted melt inclusions. We estimate that the ME could have emitted as much as 45 Tg of S to the atmosphere. This is greater than the quantity of S released by the 1815 eruption of Tambora, which contributed to the "year without a summer." Our maximum gas yield estimates place the ME among the strongest emitters of climate-forcing gases in the Common Era. However, ice cores from Greenland record only a relatively weak sulfate signal attributed to the ME. We suggest that other factors came into play in minimizing the glaciochemical signature. This paradoxical case in which high S emissions do not result in a strong glacial sulfate signal may present a way forward in building more generalized models for interpreting which volcanic eruptions have produced large climate impacts.

    Dengue fever has become a worldwide public health concern, threatening an estimated 40% of the world's population. However, most resources and attention are still focused on malaria, while dengue statuses are poorly recognized in many African countries. In this serological survey, dengue virus (DENV) transmission was demonstrated by using serum samples collected from 78 pregnant women in the Democratic Republic of Sao Tome and Principe (DRSTP) during 2003 to 2004. Immunofluorescence assay was performed and 31 samples (39.74%) were found positive for DENV antibodies. Indirect enzyme-linked immunosorbent assay (ELISA) showed that 53 samples (67.95%) were positive for dengue E IgG, and 38 samples (48.72%) were positive for NS1 IgG. A prevalence of 35.90% was therefore determined for dengue IgG by considering samples that yielded positive results by all three tests. Cross-reactions with other flaviviruses were examined by indirect ELISA against Japanese encephalitis virus, West Nile virus, and yellow fever virus. Only one sample exhibited stronger absorbance against Japanese encephalitis virus and West Nile virus. Moreover, one sample was positive for dengue IgM. These results agreed with the previous researches in neighboring countries and suggested DENV exposure. The study contributes to raising public awareness of dengue and supporting future control strategies.

    The use of self-administered questionnaires has been shown in different African countries to be inexpensive and reliable for the rapid identification of communities at highest risk of urinary schistosomiasis. For intestinal schistosomiasis due to Schistosoma mansoni there is a clear need for a similar approach. We report the results from a large-scale study undertaken in the western part of the Democratic Republic of Congo (DRC, formerly Zaire). Within 4 weeks questionnaires were correctly completed in 136 out of 160 schools (85%). In 57 of these schools children were screened for infections with schistosomes and geohelminths. The prevalence of 'schistosomiasis' as reported in the questionnaires showed the best correlation with the prevalence of S. mansoni infections (r = 0.77, P schools with a high risk of intestinal schistosomiasis gave positive predictive values of 87 and 62%, and negative predictive values of 74 and 87% for moderate and high infection thresholds, respectively. Reported 'blood in stool' was another useful indicator for intestinal schistosomiasis. Reported 'blood in urine' showed the best correlation with urinary schistosomiasis (r = 0.75, P school children in DRC have a distinct perception of intestinal and urinary schistosomiasis and that questionnaires could be useful to identify high-risk schools for both parasites.

    Ebola virus disease (EVD) can be clinically severe and highly fatal, making surveillance efforts for early disease detection of paramount importance. In areas with limited access to laboratory testing, the Integrated Disease Surveillance and Response (IDSR) strategy in the Democratic Republic of Congo (DRC) may be a vital tool in improving outbreak response. Using DRC IDSR data from the nation's four EVD outbreak periods from 2007-2014, we assessed trends of Viral Hemorrhagic Fever (VHF) and EVD differential diagnoses reportable through IDSR. With official case counts from active surveillance of EVD outbreaks, we assessed accuracy of reporting through the IDSR passive surveillance system. Although the active and passive surveillance represent distinct sets of data, the two were correlated, suggesting that passive surveillance based only on clinical evaluation may be a useful predictor of true cases prior to laboratory confirmation. There were 438 suspect VHF cases reported through the IDSR system and 416 EVD cases officially recorded across the outbreaks examined. Although collected prior to official active surveillance cases, case reporting through the IDSR during the 2007, 2008 and 2012 outbreaks coincided with official EVD epidemic curves. Additionally, all outbreak areas experienced increases in suspected cases for both malaria and typhoid fever during EVD outbreaks, underscoring the importance of training health care workers in recognising EVD differential diagnoses and the potential for co-morbidities. © 2017 John Wiley & Sons Ltd.

    This paper introduces a new theory of multiparty session types based on symmetric sum types, by which we can type non-deterministic orchestration choice behaviours. While the original branching type in session types can represent a choice made by a single participant and accepted by others...... determining how the session proceeds, the symmetric sum type represents a choice made by agreement among all the participants of a session. Such behaviour can be found in many practical systems, including collaborative workflow in healthcare systems for clinical practice guidelines (CPGs). Processes...... with the symmetric sums can be embedded into the original branching types using conductor processes. We show that this type-driven embedding preserves typability, satisfies semantic soundness and completeness, and meets the encodability criteria adapted to the typed setting. The theory leads to an efficient...

    To assess antibiotic susceptibility of community-acquired respiratory tract isolates from Ivory Coast, Kenya, Democratic Republic of Congo (DRC) and Senegal in 2011-14. Bacterial isolates were collected and MICs determined using Etest(®) for all antibiotics except erythromycin, for which testing was by disc diffusion. Susceptibility was assessed using CLSI, EUCAST and pharmacokinetic/pharmacodynamic (PK/PD) breakpoints. For macrolide interpretation, CLSI breakpoints were adjusted for incubation in CO2. Susceptibility to penicillin (using CLSI oral or EUCAST breakpoints) was low among isolates of Streptococcus pneumoniae from the DRC and Kenya (17.4% and 19%, respectively) but higher among isolates from the Ivory Coast (70%) and Senegal (85.7%). Penicillin susceptibility using CLSI iv breakpoints was higher in all countries, but still only 69.6% in the DRC. Macrolide susceptibility (based on CLSI erythromycin disc diffusion breakpoints) was also low in Kenya (∼65%) but 87%-100% elsewhere. Haemophilus influenzae were only collected in the DRC and Senegal, with β-lactamase prevalence of 39% and 4%, respectively. Furthermore, β-lactamase-negative ampicillin-resistant (BLNAR) isolates were found in DRC (four isolates, 17%), but only two isolates were found in Senegal (by EUCAST definition). Amoxicillin/clavulanic acid in vitro susceptibility was 73.9% in the DRC and 100% in Senegal based on CLSI breakpoints, but this reduced to 65.2% in the DRC when BLNAR rates were considered. Clarithromycin susceptibility was >95% in both countries. There was considerable variability in antibiotic susceptibility among the African countries participating in the surveillance programme. Thus, continued surveillance is necessary to track future changes in antibiotic resistance. Use of EUCAST versus CLSI breakpoints showed profound differences for cefaclor and ofloxacin against S. pneumoniae, with EUCAST showing lower susceptibility. © The Author 2016.

    Objectives To assess antibiotic susceptibility of community-acquired respiratory tract isolates from Ivory Coast, Kenya, Democratic Republic of Congo (DRC) and Senegal in 2011–14. Methods Bacterial isolates were collected and MICs determined using Etest® for all antibiotics except erythromycin, for which testing was by disc diffusion. Susceptibility was assessed using CLSI, EUCAST and pharmacokinetic/pharmacodynamic (PK/PD) breakpoints. For macrolide interpretation, CLSI breakpoints were adjusted for incubation in CO2. Results Susceptibility to penicillin (using CLSI oral or EUCAST breakpoints) was low among isolates of Streptococcus pneumoniae from the DRC and Kenya (17.4% and 19%, respectively) but higher among isolates from the Ivory Coast (70%) and Senegal (85.7%). Penicillin susceptibility using CLSI iv breakpoints was higher in all countries, but still only 69.6% in the DRC. Macrolide susceptibility (based on CLSI erythromycin disc diffusion breakpoints) was also low in Kenya (∼65%) but 87%–100% elsewhere. Haemophilus influenzae were only collected in the DRC and Senegal, with β-lactamase prevalence of 39% and 4%, respectively. Furthermore, β-lactamase-negative ampicillin-resistant (BLNAR) isolates were found in DRC (four isolates, 17%), but only two isolates were found in Senegal (by EUCAST definition). Amoxicillin/clavulanic acid in vitro susceptibility was 73.9% in the DRC and 100% in Senegal based on CLSI breakpoints, but this reduced to 65.2% in the DRC when BLNAR rates were considered. Clarithromycin susceptibility was >95% in both countries. Conclusions There was considerable variability in antibiotic susceptibility among the African countries participating in the surveillance programme. Thus, continued surveillance is necessary to track future changes in antibiotic resistance. Use of EUCAST versus CLSI breakpoints showed profound differences for cefaclor and ofloxacin against S. pneumoniae, with EUCAST showing lower susceptibility. PMID

    The eastern provinces of the Democratic Republic of the Congo have been identified as endemic areas for cholera transmission, and despite continuous control efforts, they continue to experience regular cholera outbreaks that occasionally spread to the rest of the country. In a region where access to improved water sources is particularly poor, the question of which improvements in water access should be prioritized to address cholera transmission remains unresolved. This study aimed at investigating the temporal association between water supply interruptions and Cholera Treatment Centre (CTC) admissions in a medium-sized town. Time-series patterns of daily incidence of suspected cholera cases admitted to the Cholera Treatment Centre in Uvira in South Kivu Province between 2009 and 2014 were examined in relation to the daily variations in volume of water supplied by the town water treatment plant. Quasi-poisson regression and distributed lag nonlinear models up to 12 d were used, adjusting for daily precipitation rates, day of the week, and seasonal variations. A total of 5,745 patients over 5 y of age with acute watery diarrhoea symptoms were admitted to the CTC over the study period of 1,946 d. Following a day without tap water supply, the suspected cholera incidence rate increased on average by 155% over the next 12 d, corresponding to a rate ratio of 2.55 (95% CI: 1.54-4.24), compared to the incidence experienced after a day with optimal production (defined as the 95th percentile-4,794 m3). Suspected cholera cases attributable to a suboptimal tap water supply reached 23.2% of total admissions (95% CI 11.4%-33.2%). Although generally reporting less admissions to the CTC, neighbourhoods with a higher consumption of tap water were more affected by water supply interruptions, with a rate ratio of 3.71 (95% CI: 1.91-7.20) and an attributable fraction of cases of 31.4% (95% CI: 17.3%-42.5%). The analysis did not suggest any association between levels of residual

    Penis size is a huge topic of anxiety for a lot of men. Some of them are unhappy with their penis size as shown in the study conducted by Tiggemann in 2008. There are relatively few studies on erect penis size. This may reflect cultural taboos of researchers or doctors interacting with men who are in a state of sexual arousal. On the other hand, it is important for people who announce details on penis size to give the average penis size first and then sizes suggested by the researchers. We performed a cross-sectional survey in the two major urban centres of the Democratic Republic of Congo namely Kinshasa and Lubumbashi over a period of two years from May 2014 to May 2016. A total of 21 information sources constituted our sample, 8 in Kinshasa and 13 in Lubumbashi. We found it sufficient because in our culture discussing about sexual matter is rare. The parameters studied were: the nature of the source, the accuracy of the measurement method, the presence of bibliographical reference, the announced penis size. The majority of information sources used were radio or television broadcastings (23,8%); this can be explained by the fact that there are an increasing number of radio and television stations in our country and especially in large cities. With regard to accuracy of information about penis measurement method when sharing the message about penis size, our study showed that the majority of information sources did not indicate it when they announced penis size to the public (85,7%). Several sources did not report bibliographical references (57,1%). Announced data analysis on penis size showed that the average penis size was: 14 cm (28,6%), 15 cm (23,8%) and 15-20 cm (19%). All these results are intended to offer a warning to all players responsible for diffusing information on sexual health (penis size): scientific rigor consists in seeking information from reliable sources.

    ABSTRACT The majority of patients with acute febrile jaundice (>95%) identified through a yellow fever surveillance program in the Democratic Republic of Congo (DRC) test negative for antibodies against yellow fever virus. However, no etiological investigation has ever been carried out on these patients. Here, we tested for hepatitis A (HAV), hepatitis B (HBV), hepatitis C (HCV), hepatitis D (HDV), and hepatitis E (HEV) viruses, all of which can cause acute febrile jaundice, in patients included in the yellow fever surveillance program in the DRC. On a total of 498 serum samples collected from suspected cases of yellow fever from January 2003 to January 2012, enzyme-linked immunosorbent assay (ELISA) techniques were used to screen for antibodies against HAV (IgM) and HEV (IgM) and for antigens and antibodies against HBV (HBsAg and anti-hepatitis B core protein [HBc] IgM, respectively), HCV, and HDV. Viral loads and genotypes were determined for HBV and HVD. Viral hepatitis serological markers were diagnosed in 218 (43.7%) patients. The seroprevalences were 16.7% for HAV, 24.6% for HBV, 2.3% for HCV, and 10.4% for HEV, and 26.1% of HBV-positive patients were also infected with HDV. Median viral loads were 4.19 × 105 IU/ml for HBV (range, 769 to 9.82 × 109 IU/ml) and 1.4 × 106 IU/ml for HDV (range, 3.1 × 102 to 2.9 × 108 IU/ml). Genotypes A, E, and D of HBV and genotype 1 of HDV were detected. These high hepatitis prevalence rates highlight the necessity to include screening for hepatitis viruses in the yellow fever surveillance program in the DRC. PMID:28202798

    Mount Paektu (also known as Changbaishan) is a large caldera located on the border between China and the Democratic People's Republic of Korea. Circa 946 AD, Paektu produced one of the largest volcanic eruptions in recorded history, the so-called Millennium Eruption (ME), whose combined fall and pyroclastic flow deposits total approximately 25 km3 dense rock equivalent (95% commendite, 5% late stage trachyte). Despite its recent and potentially destructive history, the volcano is not well studied due to its relative inaccessibility. A seismic swarm beneath the volcano's summit in 2002-2005 spurred a unique collaboration between scientists from the DPRK, US, and the UK with the goals of characterizing Paektu's eruptive history and assessing its current state of activity. We present new results from this collaboration, including major and trace element (XRF, EMP and SHRIMP-RG) and volatile data (SHRIMP-RG and FTIR) on feldspar-, clinopyroxene-, and olivine-hosted melt inclusions (MI), matrix glasses, and bulk pumices from four ME comendites and one ME trachyte. MI are halogen rich (F≤4000 ppm, Cl≤5000 ppm) with moderate S (≤250 ppm) and H2O (≤4 wt%) and minimal CO2 (≤15 ppm, detection limit ~2 ppm). H2O contents in comendite MI indicate saturation pressures (at 725 °C) of ~150 MPa, corresponding to a magma chamber depth of ~6 km, similar to the depth inferred for the magmatic injection thought to have resulted in the 2002-05 earthquake swarm. ME comendite is consistent with a ca. 25% residual melt by fractional crystallization from an ME trachyte parent. Published U-series zircon ages from ME comendite indicate a magma residence time of 11ky. Thus, the late stage ME trachyte likely represents a mafic recharge event of a melt separate from but geochemically similar to the original ME comendite parent.

    Full Text Available Abstract Background The provision of surgical assistance in conflict is often associated with care for victims of violence. However, there is an increasing appreciation that surgical care is needed for non-traumatic morbidities. In this paper we report on surgical interventions carried out by Médecins sans Frontières in Masisi, North Kivu, Democratic Republic of Congo to contribute to the scarce evidence base on surgical needs in conflict. Methods We analysed data on all surgical interventions done at Masisi district hospital between September 2007 and December 2009. Types of interventions are described, and logistic regression used to model associations with violence-related injury. Results 2869 operations were performed on 2441 patients. Obstetric emergencies accounted for over half (675, 57% of all surgical pathology and infections for another quarter (160, 14%. Trauma-related injuries accounted for only one quarter (681, 24% of all interventions; among these, 363 (13% were violence-related. Male gender (adjusted odds ratio (AOR = 20.0, p Conclusions In this study, most surgical interventions were unrelated to violent trauma and rather reflected the general surgical needs of a low-income tropical country. Programs in conflict zones in low-income countries need to be prepared to treat both the war-wounded and non-trauma related life-threatening surgical needs of the general population. Given the limited surgical workforce in these areas, training of local staff and task shifting is recommended to support broad availability of essential surgical care. Further studies into the surgical needs of the population are warranted, including population-based surveys, to improve program planning and resource allocation and the effectiveness of the humanitarian response.

  1. Improving financial access to health care in the Kisantu district in the Democratic Republic of Congo: acting upon complexity

    Full Text Available Background: Comzmercialization of health care has contributed to widen inequities between the rich and the poor, especially in settings with suboptimal regulatory frameworks of the health sector. Poorly regulated fee-for-service payment systems generate inequity and initiate a vicious circle in which access to quality health care gradually deteriorates. Although the abolition of user fees is high on the international health policy agenda, the sudden removal of user fees may have disrupting effects on the health system and may not be affordable or sustainable in resource-constrained countries, such as the Democratic Republic of Congo. Methods and Results: Between 2008 and 2011, the Belgian development aid agency (BTC launched a set of reforms in the Kisantu district, in the province of Bas Congo, through an action-research process deemed appropriate for the implementation of change within open complex systems such as the Kisantu local health system. Moreover, the entire process contributed to strengthen the stewardship capacity of the Kisantu district management team. The reforms mainly comprised the rationalization of resources and the regulation of health services financing. Flat fees per episode of disease were introduced as an alternative to fee-for-service payments by patients. A financial subsidy from BTC allowed to reduce the height of the flat fees. The provision of the subsidy was made conditional upon a range of measures to rationalize the use of resources. Conclusions: The results in terms of enhancing people access to quality health care were immediate and substantial. The Kisantu experience demonstrates that a systems approach is essential in addressing complex problems. It provides useful lessons for other districts in the country.

    Full Text Available BACKGROUND: Until the 1970s the prevalence of non-venereal trepanomatosis, including yaws, was greatly reduced after worldwide mass treatment. In 2005, cases were again reported in the Democratic Republic of the Congo. We carried out a survey to estimate the village-level prevalence of yaws in the region of Equator in the north of the country in order to define appropriate strategies to effectively treat the affected population. METHODOLOGY/PRINCIPAL FINDINGS: We designed a community-based survey using the Lot Quality Assurance Sampling method to classify the prevalence of active yaws in 14 groups of villages (lots. The classification into high, moderate, or low yaws prevalence corresponded to World Health Organization prevalence thresholds for identifying appropriate operational treatment strategies. Active yaws cases were defined by suggestive clinical signs and positive rapid plasma reagin and Treponema pallidum hemagglutination serological tests. The overall prevalence in the study area was 4.7% (95% confidence interval: 3.4-6.0. Two of 14 lots had high prevalence (>10%, three moderate prevalence (5-10% and nine low prevalence (<5%.. CONCLUSIONS/SIGNIFICANCE: Although yaws is no longer a World Health Organization priority disease, the presence of yaws in a region where it was supposed to be eradicated demonstrates the importance of continued surveillance and control efforts. Yaws should remain a public health priority in countries where previously it was known to be endemic. The integration of sensitive surveillance systems together with free access to effective treatment is recommended. As a consequence of our study results, more than 16,000 people received free treatment against yaws.

    Full Text Available BACKGROUND: Cutaneous infection by Mycobacterium ulcerans, also known as Buruli ulcer (BU, represents the third most common mycobacterial disease in the world after tuberculosis and leprosy. Data on the burden of BU disease in the Democratic Republic of Congo are scanty. This study aimed to estimate the prevalence rate and the distribution of BU in the Songololo Territory, and to assess the coverage of the existing hospital-based reporting system. METHODS: We conducted a cross-sectional survey (July-August 2008 using the door-to-door method simultaneously in the two rural health zones (RHZ of the Songololo Territory (RHZ of Kimpese and Nsona-Mpangu, each containing twenty health areas. Cases were defined clinically as active BU and inactive BU in accordance with WHO-case definitions. RESULTS: We detected 775 BU patients (259 active and 516 inactive in a total population of 237,418 inhabitants. The overall prevalence of BU in Songololo Territory was 3.3/1000 inhabitants, varying from 0 to 27.5/1000 between health areas. Of the 259 patients with active BU, 18 (7% had been reported in the hospital-based reporting system at Kimpese in the 6-8 months prior to the survey. CONCLUSION: The survey demonstrated a huge variation of prevalence between health areas in Songololo Territory and gross underreporting of BU cases in the hospital-based reporting system. Data obtained may contribute to better targeted and improved BU control interventions, and serve as a baseline for future assessments of the control program.

    In order to determine the prevalence of thalassemia and hemoglobinopathies in different regions of northeast (NE) Thailand and Vientiane, Laos People's Democratic Republic (PDR), a total of 1,809 blood samples were collected consecutively from individuals attending antenatal care services at 11 community hospitals in different regions of NE Thailand and three hospitals in Vientiane, Laos PDR, from May 2009 to April 2010. All individuals were investigated for thalassemia and hemoglobinopathies using standard methods. For individuals from NE Thailand, the carrier frequencies were 41.7% for Hb E [β26(B8)Glu→Lys, GAG>AAG], 5.8% for α(0)-thalassemia (α(0)-thal), and 0.9% for β-thal. The THAI deletion type of α(0)-thal was found in one individual from an ethnic minority. From a group of pregnant Laotian women, 30.1% were Hb E carriers. The prevalence of α(0)-thal of 8.6% for the Laotian women was similar to that found in the upper northeastern part of Thailand. The frequency of β-thal was 2.3 %. The proportion of carriers of α(+)-thal and Hb Constant Spring (Hb CS, α142, Term→Gln (TAA>CAA in α2)] ) from Thailand and Laos was significantly different. The frequency of Hb Paksé [α142, Term→Tyr (TAA>TAT in α2)] was relatively low for Thailand as well as for Laos. The results indicate that thalassemia and hemoglobinopathies are a significant health burden in the region and that a prevention and control program for severe thalassemia diseases should be established in Laos.

    The need for quantitative and accurate information to characterize the state and evolution of vegetation types at a national scale is widely recognized. This type of information is crucial for the Democratic Republic of Congo, which contains the majority of the tropical forest cover of Central Africa and a large diversity of habitats. In spite of recent progress in earth observation capabilities, vegetation mapping and seasonality analysis in equatorial areas still represent an outstanding challenge owing to high cloud coverage and the extent and limited accessibility of the territory. On one hand, the use of coarse-resolution optical data is constrained by performance in the presence of cloud screening and by noise arising from the compositing process, which limits the spatial consistency of the composite and the temporal resolution. On the other hand, the use of high-resolution data suffers from heterogeneity of acquisition dates, images and interpretation from one scene to another. The objective of the present study was to propose and demonstrate a semi-automatic processing method for vegetation mapping and seasonality characterization based on temporal and spectral information from SPOT VEGETATION time series. A land cover map with 18 vegetation classes was produced using the proposed method that was fed by ecological knowledge gathered from botanists and reference documents. The floristic composition and physiognomy of each vegetation type are described using the Land Cover Classification System developed by the FAO. Moreover, the seasonality of each class is characterized on a monthly basis and the variation in different vegetation indicators is discussed from a phenological point of view. This mapping exercise delivers the first area estimates of seven different forest types, five different savannas characterized by specific seasonality behavior and two aquatic vegetation types. Finally, the result is compared to two recent land cover maps derived from

    Extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae are a major public health concern. We previously demonstrated the presence of ESBL-producing Enterobacteriaceae in sachet-packaged water bags sold in Kinshasa, the Democratic Republic of the Congo. In complement to the previous study, we aimed to assess the presence of ESBL-producing Enterobacteriaceae in waste waters in Kinshasa.Enterobacteriaceae isolates recovered from environmental water samples were screened and phenotypically confirmed as ESBL-producers by disk diffusion according to Clinical and Laboratory Standards Institute (CLSI) guidelines (CLSI M100-S21). Final identification to the species level and further antimicrobial susceptibility testing were carried out with MicroScan® NBC42 panels and the identification of bla (ESBL) coding genes was performed by a commercial multiplex ligation polymerase chain reaction (PCR) microarray (Check-Points CT 101, Wageningen, the Netherlands). Overall, 194 non-duplicate Enterobacteriaceae were recovered from several sewer and river sites in nine out of 24 municipalities of Kinshasa. Fourteen isolates (7.4 %) were confirmed as ESBL-producers, the main species being Enterobacter cloacae (46.6 %) and Klebsiella pneumoniae (40.0 %). Associated resistance to both aminoglycoside and fluoroquinolone antibiotics was observed in ten isolates; the remaining isolates showed co-resistance to either fluoroquinolone (n = 3) or to aminoglycoside (n = 1) alone. All but one isolate carried bla (CTX-M) genes belonging to the CTX-M-1 group. ESBL-producing Enterobacteriaceae are increasingly being reported from various sources in the community. The present results suggest that ESBL-producing Enterobacteriaceae are widespread in the environment in the community of Kinshasa. Cities in Central Africa should be added to the map of potentially ESBL-contaminated environments and highlight the need to reinforce safe water supply and public sanitation.

    Recent advances in remote sensing enable the mapping and monitoring of carbon stocks without relying on extensive in situ measurements. The Democratic Republic of the Congo (DRC) is among the countries where national forest inventories (NFI) are either non-existent or out of date. Here we demonstrate a method for estimating national-scale gross forest aboveground carbon (AGC) loss and associated uncertainties using remotely sensed-derived forest cover loss and biomass carbon density data. Lidar data were used as a surrogate for NFI plot measurements to estimate carbon stocks and AGC loss based on forest type and activity data derived using time-series multispectral imagery. Specifically, DRC forest type and loss from the FACET (Forêts d’Afrique Centrale Evaluées par Télédétection) product, created using Landsat data, were related to carbon data derived from the Geoscience Laser Altimeter System (GLAS). Validation data for FACET forest area loss were created at a 30-m spatial resolution and compared to the 60-m spatial resolution FACET map. We produced two gross AGC loss estimates for the DRC for the last decade (2000-2010): a map-scale estimate (53.3 ± 9.8 Tg C yr-1) accounting for whole-pixel classification errors in the 60-m resolution FACET forest cover change product, and a sub-grid estimate (72.1 ± 12.7 Tg C yr-1) that took into account 60-m cells that experienced partial forest loss. Our sub-grid forest cover and AGC loss estimates, which included smaller-scale forest disturbances, exceed published assessments. Results raise the issue of scale in forest cover change mapping and validation, and subsequent impacts on remotely sensed carbon stock change estimation, particularly for smallholder dominated systems such as the DRC.

    Past disturbances have modified local density, structure and floristic composition of Central African rainforests. As such, these perturbations represent a driving force for forest dynamics and they were presumably at the origin of present-day forest mosaics. One of the most prominent disturbances within the forest is fire, leaving behind charcoal as a witness of past forest dynamics. Quantification and identification of ancient charcoal fragments found in soil layers (= pedoanthracology) allows a detailed reconstruction of forest history, including the possible occurrence of past perturbations. The primary objective of this study is to present palaeoenvironmental evidence for the existence of past disturbances in the forests of the Kisangani region (Democratic Republic of the Congo) using a pedoanthracological approach. We quantified and identified charcoal fragments from pedoanthracological excavations in the Yangambi, Yoko, Masako and Kole forest regions. Charcoal sampling was conducted in pit intervals of 10 cm, whereby pottery fragments were also registered and quantified. Floristic identifications were conducted using former protocols based on wood anatomy, which is largely preserved after charcoalification. 14 excavations were conducted and charcoal was found in most pit intervals. Specifically, 52 out of 56 sampled intervals from the Yangambi forest contained charcoal, along with 47 pit intervals from the Yoko forest reserve, 34 pit intervals from the Masako forest and 16 from the Kole forest. Highest specific anthracomasses were recorded in Yoko (167 mg charcoal per kg soil), followed by Yangambi (133 mg/kg), Masako (71,89 mg/kg) and finally Kole (42,4 mg/kg). Charcoal identifications point at a manifest presence of the family of Fabaceae (Caesalpinioideae). This family is characteristic for the tropical humid rainforest. The presence of charcoal fragments from these taxa, associated with pottery sherds on different depths within the profiles, suggests

    Full Text Available Abstract Background The conflict in eastern Democratic Republic of the Congo (DRC is the deadliest since World War II. Over a decade of fighting amongst an array of armed groups has resulted in extensive human rights abuses, particularly the widespread use of sexual violence against women. Methods Using a mixed-methods approach, we surveyed a non-random sample of 255 women attending a referral hospital and two local non-governmental organizations to characterize their experiences of sexual and gender-based violence (SGBV. We then conducted focus groups of 48 women survivors of SGBV to elaborate on survey findings. Quantitative and qualitative data underwent thematic and statistical analysis respectively. Findings Of the women surveyed, 193 (75.7% experienced rape. Twenty-nine percent of raped women were rejected by their families and 6% by their communities. Thirteen percent of women had a child from rape. Widowhood, husband abandonment, gang rape, and having a child from rape were significant risk factors for social rejection. Mixed methods findings show rape survivors were seen as "contaminated" with HIV, contributing to their isolation and over 95% could not access prophylactic care in time. Receiving support from their husbands after rape was protective against survivors' feelings of shame and social isolation. Interpretation Rape results not only in physical and psychological trauma, but can destroy family and community structures. Women face significant obstacles in seeking services after rape. Interventions offering long-term solutions for hyper-vulnerable women are vital, but lacking; reintegration programs on SGBV for women, men, and communities are also needed.

    Full Text Available Background: Health and social services utilisation is seen to be more closely related to age than to other socio-demographic characteristics. Many health problems are known to increase with age and this demographic trend may lead to an increase in the absolute number of health conditions in this population. However, questions are still emerging as to how the elderly seek care in response to their needs in the context of a war-torn region. Objectives: The aim of this study was to determine the behaviour of the elderly in seeking care during a time of conflict.Method: A descriptive cross-sectional study was carried out in the health district Goma, in the Democratic Republic of the Congo (DRC, using a multistage sampling of 500 senior citizens. Eight trained field-workers were deployed in the field where they administered a structured questionnaire.Results: The public health sector was well known and preferred by 186 participants (37.2%, but only used by 16 (3.2% participants. Financial support received by the elderly came from their own relatives and fellow believers in 33.5% and 20.2% of cases, respectively. Almost 71% of monetary support is the result of begging and unknown sources – there is no government involvement whatsoever. Much of the external support that the elderly receive involves support in the form of food. Disease expenses remain a main concern of the elderly themselves.Conclusion: Government support for the elderly in the DRC is non-existent. There is an overuse of private sector and traditional medicine, despite the preference indicated for the public health sector. As a recommendation, a general increase in income-related activities could contribute to alleviating the health state of the elderly in a war situation. Further studies might explore in future the contribution of those results on the health of elders.

    Comzmercialization of health care has contributed to widen inequities between the rich and the poor, especially in settings with suboptimal regulatory frameworks of the health sector. Poorly regulated fee-for-service payment systems generate inequity and initiate a vicious circle in which access to quality health care gradually deteriorates. Although the abolition of user fees is high on the international health policy agenda, the sudden removal of user fees may have disrupting effects on the health system and may not be affordable or sustainable in resource-constrained countries, such as the Democratic Republic of Congo. Between 2008 and 2011, the Belgian development aid agency (BTC) launched a set of reforms in the Kisantu district, in the province of Bas Congo, through an action-research process deemed appropriate for the implementation of change within open complex systems such as the Kisantu local health system. Moreover, the entire process contributed to strengthen the stewardship capacity of the Kisantu district management team. The reforms mainly comprised the rationalization of resources and the regulation of health services financing. Flat fees per episode of disease were introduced as an alternative to fee-for-service payments by patients. A financial subsidy from BTC allowed to reduce the height of the flat fees. The provision of the subsidy was made conditional upon a range of measures to rationalize the use of resources. The results in terms of enhancing people access to quality health care were immediate and substantial. The Kisantu experience demonstrates that a systems approach is essential in addressing complex problems. It provides useful lessons for other districts in the country.

    Between 2011 and 2013 the number of recorded malaria cases had more than doubled, and between 2009 and 2013 had increased almost 4-fold in MSF-OCA (Médecins sans Frontières - Operational Centre Amsterdam) programmes in the Democratic Republic of the Congo (DRC). The reasons for this rise are unclear. Incorrect intake of Artemisinin Combination Therapy (ACT) could result in failure to treat the infection and potential recurrence. An adherence study was carried out to assess whether patients were completing the full course of ACT. One hundred and eight malaria patients in Shamwana, Katanga province, DRC were visited in their households the day after ACT was supposed to be completed. They were asked a series of questions about ACT administration and the blister pack was observed (if available). Sixty seven (62.0%) patients were considered probably adherent. This did not take into account the patients that vomited or spat their pills or took them at the incorrect time of day, in which case adherence dropped to 46 (42.6%). The most common reason that patients gave for incomplete/incorrect intake was that they were vomiting or felt unwell (10 patients (24.4%), although the reasons were not recorded for 22 (53.7%) patients). This indicates that there may be poor understanding of the importance of completing the treatment or that the side effects of ACT were significant enough to over-ride the pharmacy instructions. Adherence to ACT was poor in this setting. Health education messages emphasising the need to complete ACT even if patients vomit doses, feel unwell or their health conditions improve should be promoted.

    Full Text Available Abstract Background Since 1998, the Eastern Democratic Republic of the Congo has been torn by a military conflict. A particular atrocity of the war is widespread sexual violence. Methods In this combined retrospective analysis and prospective survey, we sought to identify hospital facilities and resources available to treat victims of sexual violence in Goma, the capital city of the North Kivu province. Results Of twenty-three acute care hospitals registered in the area of Goma, four (17% regularly cared for victims of sexual violence. One hospital had all resources always available to appropriately care for victims of sexual violence. From Jan 2009 until Oct 2010, 7,048 females sought medical care because of physical or psychological sequelae from sexual violence in the four hospitals of Goma. Only half of the hospitals had physicians specialized in gynaecology or gynaecological surgery available. Similarly, anaesthetists and psychiatrists/psychologists were available in two (50% and one (25% hospital, respectively. Post-discharge care facilities, material resources, such as surgical and anaesthesiological equipment and drugs, were inconsistently available in the hospitals caring for sexually abused females. At one selected hospital, acyclovir and/or antibiotics were administered to 1,202 sexually abused females (89.5%, whereas post-exposure HIV prophylaxis and surgery because of vesico-vaginal fistula was provided to only 75 (5.6% and 121 (9% patients, respectively. Conclusions This study provides data that only few hospitals in Goma care for victims of sexual violence. In addition, these hospitals suffer from a relevant shortage of human and material resources to provide adequate care for sexually abused females. Aside from establishment of adequate protection strategies, steps must be taken to increase the availability of trained health care professionals and resources to provide adequate care for victims of sexual violence in Goma and the

    Full Text Available Cassava mosaic disease (CMD is reported as the most important constraint on cassava production in Sub­Saharan Africa. Yield losses of 25­95% are reported. The use of resistant genotypes is one of the components for its integrated management. However its impact on genotype behavior depends on infection period, age of the infected plants, environment and virus species or strain. This study was carried out to assess its impact in farmers' fields and the behavior of 14 genotypes under high epidemic pressure in the Sud­Kivu province, in the East of Democratic Republic of Congo (DRC. Early infections have induced 77.5% to 97.3% of yield losses whereas 44.9 to 80% were recorded for cassava plants infected during thirteenth to twenty­fourth weeks after planting. The highest yield losses were recorded in low altitude where more EACMV­UG and dual infections were reported. Improved resistant genotypes MM96/002, MM96/0157 and MM96/1920 allowed harvesting more than 30 T/ha and didn't show any symptoms whereas MM96/6967 and Mvuama have developed symptoms at harvest. Local landraces were susceptible to CMD and developed symptoms during the whole season until harvest. However two of them, Pharmakina and Cizinduka yielded more than 50 T/ha of tubers and associated symptoms were moderate. Two improved and two local cassava genotypes are recommended in this area always making sure to use healthy cuttings.

    Full Text Available Abstract Background Although there are inequalities in child health and survival in the Democratic Republic of Congo (DRC, the influence of distal determinants such as geographic location on children's nutritional status is still unclear. We investigate the impact of geographic location on child nutritional status by mapping the residual net effect of malnutrition while accounting for important risk factors. Methods We examine spatial variation in under-five malnutrition with flexible geo-additive semi-parametric mixed model while simultaneously controlling for spatial dependence and possibly nonlinear effects of covariates within a simultaneous, coherent regression framework based on Markov Chain Monte Carlo techniques. Individual data records were constructed for children. Each record represents a child and consists of nutritional status information and a list of covariates. For the 8,992 children born within the last five years before the survey, 3,663 children have information on anthropometric measures. Our novel empirical approach is able to flexibly determine to what extent the substantial spatial pattern of malnutrition is driven by detectable factors such as socioeconomic factors and can be attributable to unmeasured factors such as conflicts, political, environmental and cultural factors. Results Although childhood malnutrition was more pronounced in all provinces of the DRC, after accounting for the location's effects, geographic differences were significant: malnutrition was significantly higher in rural areas compared to urban centres and this difference persisted after multiple adjustments. The findings suggest that models of nutritional intervention must be carefully specified with regard to residential location. Conclusion Childhood malnutrition is spatially structured and rates remain very high in the provinces that rely on the mining industry and comparable to the level seen in Eastern provinces under conflicts.

    To evaluate the self-reported oral health habits and their association with the occurrence of dental caries among children in Pyongyang, Democratic People's Republic of Korea (DPRK), after 6 years of activities under the auspices of the Children's Oral Health Promotion Programme (COHPP). The data were collected in September 2013 in two of the most central districts of Pyongyang City, DPRK. The sample consisted of 492 children aged 10 and 13 years who had participated in the COHPP for 6 years. The children filled in a self-completed, structured questionnaire on oral health habits and were examined clinically by a dentist. The differences in mean (SD) number of decayed primary (dt) and permanent teeth (DT) and their sum (dt + DT) subdivided according to genders, age groups, districts and self-reported oral health habits were evaluated using Mann-Whitney U-test. The associations between self-reported oral health habits and the occurrence of dental caries were evaluated with chi-square test and logistic regression analyses. The school-aged children commonly reported healthy oral hygiene habits but sweet snacks were commonly used. The occurrence of dental caries associated statistically significantly with the frequency of sweet snacking (p=0.011) but not with the frequency of tooth brushing (p=0.725) or the use of water for thirst instead of sugary beverages (p=0.189). A more effective promotion of healthy dietary habits with innovative approaches and close collaboration with different social actors will be needed in future. © 2016 John Wiley & Sons A/S.

    To determine the availability and quality of family planning services within health facilities throughout the Democratic Republic of the Congo (DRC). Data were collected for the cross-sectional study from April 2014 to June 2014 by the Ministry of Public Health. A total of 1,568 health facilities that reported data to the National Health Information System were selected by multistage random sampling in the 11 provinces of the DRC existing at that time. Data were collected through interviews, document review, and direct observation. Two dependent variables were measured: availability of family planning services (consisting of a room for services, staff assigned to family planning, and evidence of client use of family planning) and quality of family planning services (assessed as "high" if the facility had at least 1 trained staff member, family planning service delivery guidelines, at least 3 types of methods, and a sphygmomanometer, or "low" if the facility did not meet any of these 4 criteria). Pearson's chi-square test and odds ratios (ORs) were used to test for significant associations, using the alpha significance level of .05. We successfully surveyed 1,555 facilities (99.2%) of those included in the sample. One in every 3 facilities (33%) offered family planning services as assessed by the index of availability, of which 20% met all 4 criteria for providing high-quality services. Availability was greatest at the highest level of the health system (hospitals) and decreased incrementally with each health system level, with disparities between provinces and urban and rural areas. Facilities in urban areas were more likely than in rural areas to meet the standard for high-quality services (Pplanning services in health facilities in the DRC remain low, with inequitable distribution of services throughout the country. To improve access to and use of family planning, efforts should focus on improving availability and quality at lower health system levels and in

    Prevalence of child stunting in the Democratic Republic of Congo (DRC) is among the highest in the world. There is a need to systematically investigate how stunting operates at different levels of determination and identify major factors contributing to the development of stunting. The aim of this study was to look for key determinants of stunting in the DRC. This study used data from the DRC Demographic Health Survey 2013-14 which included anthropometric measurement for 9030 under 5 year children. Height-for-Age Z score was calculated and classified according to the WHO guideline. The association between stunting and bio-demographic characteristics was assessed using logistic regression. Prevalence of stunting was much higher in boys than girls. There was a significant rural urban gap in the prevalence of stunting with rural areas having a larger proportion of children living with stunting than urban. Male children, older than 6 months, preceding birth interval less than 24 months, being from lower wealth quintiles had the highest odds of stunting. Several provinces had in particular high odds of stunting. Early initiation of breastfeeding, mother's age more than 20 years at the time of delivery had lower odds of stunting. The taller the mother the less likely the child was to be stunted. Similarly, mother's BMI, access to safe water, access to hygienic toilet, mother's education were found negatively correlated with child stunting in the bivariate logistic regression, but they lost statistical significance in multivariate analysis together with numbers of children in the family and place of residence. Child stunting is widespread in the DRC and increasing prevalence is worrisome. This study has identified modifiable factors determining high prevalence of stunting in the DRC. Policy implementation should in particular target provinces with high prevalence of stunting and address modifiable determinants such as reducing socioeconomic disparity. Nutrition

    Full Text Available BACKGROUND: Control of human African trypanosomiasis (sleeping sickness in the Democratic Republic of Congo is based on mass population active screening by mobile teams. Although generally considered a successful strategy, the community participation rates in these screening activities and ensuing treatment remain low in the Kasai-Oriental province. A better understanding of the reasons behind this observation is necessary to improve regional control activities. METHODS: Thirteen focus group discussions were held in five health zones of the Kasai-Oriental province to gain insights in the regional perceptions regarding sleeping sickness and the national control programme's activities. PRINCIPAL FINDINGS: Sleeping sickness is well known among the population and is considered a serious and life-threatening disease. The disease is acknowledged to have severe implications for the individual (e.g., persistence of manic periods and trembling hands, even after treatment, at the family level (e.g., income loss, conflicts, separations and for communities (e.g., disruption of community life and activities. Several important barriers to screening and treatment were identified. Fear of drug toxicity, lack of confidentiality during screening procedures, financial barriers and a lack of communication between the mobile teams and local communities were described. Additionally, a number of regionally accepted prohibitions related to sleeping sickness treatment were described that were found to be a strong impediment to disease screening and treatment. These prohibitions, which do not seem to have a rational basis, have far-reaching socio-economic repercussions and severely restrict the participation in day-to-day life. CONCLUSIONS/SIGNIFICANCE: A mobile screening calendar more adapted to the local conditions with more respect for privacy, the use of less toxic drugs, and a better understanding of the origin as well as better communication about the prohibitions

  2. Taenia solium cysticercosis in the Democratic Republic of Congo: how does pork trade affect the transmission of the parasite?

    Directory of Open Access Journals (Sweden)

    Nicolas Praet

    Full Text Available BACKGROUND: Taenia solium, a zoonotic parasite that is endemic in most developing countries where pork is consumed, is recognised as the main cause of acquired epilepsy in these regions. T. solium has been reported in almost all of the neighboring countries of Democratic Republic of Congo (DRC but data on the current prevalence of the disease in the country itself are lacking. This study, focusing on porcine cysticercosis (CC, makes part of a first initiative to assess whether cysticercosis is indeed actually present in DRC. METHODS: An epidemiological study on porcine CC was conducted (1 on urban markets of Kinshasa where pork is sold and (2 in villages in Bas-Congo province where pigs are traditionally reared. Tongue inspection and ELISA for the detection of circulating antigen of the larval stage of T. solium were used to assess the prevalence of active CC in both study sites. FINDINGS: The overall prevalence of pigs with active cysticercosis did not significantly differ between the market and the village study sites (38.8 [CI 95%: 34-43] versus 41.2% [CI 95%: 33-49], respectively. However, tongue cysticercosis was only found in the village study site together with a significantly higher intensity of infection (detected by ELISA. INTERPRETATION: Pigs reared at village level are sold for consumption on Kinshasa markets, but it seems that highly infected animals are excluded at a certain level in the pig trade chain. Indeed, preliminary informal surveys on common practices conducted in parallel revealed that pig farmers and/or buyers select the low infected animals and exclude those who are positive by tongue inspection at village level. This study provides the only recent evidence of CC presence in DRC and gives the first estimates to fill an important gap on the African taeniasis/cysticercosis distribution map.

    Using entanglement of assistance, we establish a general polygamy inequality of multiparty entanglement in arbitrary-dimensional quantum systems. For multiparty closed quantum systems, we relate our result with the monogamy of entanglement, and clarify that the entropy of entanglement bounds both monogamy and polygamy of multiparty quantum entanglement.

    Our purpose in this study is to describe the multiple and inter-related health, economic, and social reasons for rejection and to provide an example of a Congolese-led family mediation program to reintegrate survivors into their families. We conducted this study in Eastern Democratic Republic of Congo (DRC) and included two focus group discussions and twenty-seven interviews. Rejection extends beyond physical dislocation to include economic and social aspects. Family mediation is a process requiring knowledge of traditions and norms. Understanding the context of rejection and supporting promising local reintegration efforts will likely improve health, economic, and social outcomes for the survivor, her family, and her community.

    @@ A multiparty quantum secret report scheme is proposed with quantum encryption. The boss Alice and her M agents first share a sequence of (M + 1)-particle Greenberger-Horne-Zeilinger (GHZ) states that only Alice knows which state each (M + 1)-particle quantum system is in. Each agent exploits a controlled-not (CNot) gate to encrypt the travelling particle by using the particle in the GHZ state as the control qubit. The boss Alice decrypts the travelling particle with a CNot gate after performing a σx operation on her particle in the GHZ state or not.After the GHZ states (the quantum key) are used up, the parties check whether there is a vicious eavesdropper,say Eve, monitoring the quantum line, by picking out some samples from the GHZ states shared and measuring them with two measuring bases. After confirming the security of the quantum key, they use the remaining GHZ states repeatedly for the next round of quantum communication. This scheme has the advantage of high intrinsic efficiency for the qubits and total efficiency.

    We analyze different aspects of multiparty communication over quantum memoryless channels and generalize some of key results known from bipartite channels to that of multiparty scenario. In particular, we introduce multiparty versions of minimal subspace transmission fidelity and entanglement transmission fidelity. We also provide alternative, local, versions of fidelities and show their equivalence to the global ones in context of capacity regions defined. The equivalence of two different capacity notions with respect to two types of the fidelities is proven.

    Road traffic accident (RTA)-related trauma remains a public health issue. The aim of this study was to determine the frequency, causes and human impact of motor vehicle-related RTA in Lubumbashi, Democratic Republic of Congo. A prospective cross-sectional study was conducted in the first semester of the year 2015 in which 288 drivers (144 RTA-causing drivers and 144 control drivers who have been declared not guilty by road safety agents) involved in 144 motor vehicle-related RTA were interviewed, and only data on all RTA involving two motor vehicles with at least four wheels were recorded and analyzed. Results showed a total of 144 RTA that involved two motor vehicles with four wheels occurring during the study period which affected 104 people, including 93 injury and 11 fatality cases. The mean age of RTA-causing drivers was 33.8 ± 7.4, whereas it was 35 ± 8.8 for control drivers. The majority of RTA-causing drivers (53.4 %) did not attend a driving school. Over speeding (32 %), distracted driving (22 %), overtaking (16 %) and careless driving/risky maneuver (15 %) and driving under the influence of alcohol (9 %) were the main causes of RTA occurrence. In addition, the absence of a valid driving license [aOR = 12.74 (±2.71); 95 % CI 3.877-41.916; p = 0.015], unfastened seat belt for the RTA-causing driver [aOR = 1.85 (±0.62); 95 % CI 1.306-6.661; p = 0.048] and presence of damages on RTA-causing vehicle [aOR = 33.56 (24.01); 95 % CI 1.429-78.352; p = 0.029] were associated with the occurrence of RTA-related fatality. This study showed a relatively high frequency of RTA occurring in Lubumbashi and suggests the necessity to reinforce road traffic regulation.

    Full Text Available Abstract Background Zoonotic transmission of simian retroviruses in Central Africa is ongoing and can result in pandemic human infection. While simian foamy virus (SFV infection was reported in primate hunters in Cameroon and Gabon, little is known about the distribution of SFV in Africa and whether human-to-human transmission and disease occur. We screened 3,334 plasmas from persons living in rural villages in central Democratic Republic of Congo (DRC using SFV-specific EIA and Western blot (WB tests. PCR amplification of SFV polymerase sequences from DNA extracted from buffy coats was used to measure proviral loads. Phylogenetic analysis was used to define the NHP species origin of SFV. Participants completed questionnaires to capture NHP exposure information. Results Sixteen (0.5% samples were WB-positive; 12 of 16 were from women (75%, 95% confidence limits 47.6%, 92.7%. Sequence analysis detected SFV in three women originating from Angolan colobus or red-tailed monkeys; both monkeys are hunted frequently in DRC. NHP exposure varied and infected women lived in distant villages suggesting a wide and potentially diverse distribution of SFV infections across DRC. Plasmas from 22 contacts of 8 WB-positive participants were all WB negative suggesting no secondary viral transmission. Proviral loads in the three women ranged from 14 – 1,755 copies/105 cells. Conclusions Our study documents SFV infection in rural DRC for the first time and identifies infections with novel SFV variants from Colobus and red-tailed monkeys. Unlike previous studies, women were not at lower risk for SFV infection in our population, providing opportunities for spread of SFV both horizontally and vertically. However, limited testing of close contacts of WB-positive persons did not identify human-to-human transmission. Combined with the broad behavioral risk and distribution of NHPs across DRC, our results suggest that SFV infection may have a wider geographic

    Full Text Available Abstract Background Asymptomatic malaria can be observed in both stable endemic areas and unstable transmission areas. However, although much attention has been given to acute malaria infections, relatively little attention has been paid to asymptomatic malaria. Nonetheless, because the asymptomatic host serves as a reservoir for the malaria parasite, asymptomatic malaria is now recognized as an important obstacle to malaria elimination. Asymptomatic malaria is also associated with anaemia, a global public health problem with serious consequences on human health as well as social and economic development. In Lao People’s Democratic Republic (Lao PDR, malaria, anaemia, and malnutrition are serious public health concerns. However, few studies have focused on the relationship between these variables. Therefore, this study investigated the relationship between asymptomatic malaria, growth status, and the prevalence of anaemia among children aged 120 months old or younger in rural villages in Lao PDR. Methods In December 2010 and March 2011, data were collected from five villages in Savannakhet province. Anthropometric measurements, blood samples, and malaria rapid diagnostic tests were conducted. The presence of malaria was confirmed with polymerase chain reaction assays for Plasmodium falciparum. Underweight status, stunting, and anaemia were defined according to World Health Organization standards. Results The mean age of participants (n = 319 was 88.3 months old (Standard Deviation: 20.6, ranged from 30–119 months old, and 20 participants (6.3 % had an asymptomatic malaria infection, 92 (28.8 % were anaemic, 123 (38.6 % were underweight, and 137 (42.9 % were stunted.

    ABSTRACT As the epidemiological epicenter of the human immunodeficiency virus (HIV) pandemic, the Democratic Republic of the Congo (DRC) is a reservoir of circulating HIV strains exhibiting high levels of diversity and recombination. In this study, we characterized HIV specimens collected in two rural areas of the DRC between 2001 and 2003 to identify rare strains of HIV. The env gp41 region was sequenced and characterized for 172 HIV-positive specimens. The env sequences were predominantly subtype A (43.02%), but 7 other subtypes (33.14%), 20 circulating recombinant forms (CRFs; 11.63%), and 20 unclassified (11.63%) sequences were also found. Of the rare and unclassified subtypes, 18 specimens were selected for next-generation sequencing (NGS) by a modified HIV-switching mechanism at the 5′ end of the RNA template (SMART) method to obtain full-genome sequences. NGS produced 14 new complete genomes, which included pure subtype C (n = 2), D (n = 1), F1 (n = 1), H (n = 3), and J (n = 1) genomes. The two subtype C genomes and one of the subtype H genomes branched basal to their respective subtype branches but had no evidence of recombination. The remaining 6 genomes were complex recombinants of 2 or more subtypes, including subtypes A1, F, G, H, J, and K and unclassified fragments, including one subtype CRF25 isolate, which branched basal to all CRF25 references. Notably, all recombinant subtype H fragments branched basal to the H clade. Spatial-geographical analysis indicated that the diverse sequences identified here did not expand globally. The full-genome and subgenomic sequences identified in our study population significantly increase the documented diversity of the strains involved in the continually evolving HIV-1 pandemic. IMPORTANCE Very little is known about the ancestral HIV-1 strains that founded the global pandemic, and very few complete genome sequences are available from patients in the Congo Basin, where HIV-1 expanded early in the global pandemic

    Full Text Available Abstract Background Despite the signing of international peace agreements, a deadly war continues in the Democratic Republic of Congo (DRC and sexual violence is a prominent modus operandi of many military groups operating in the region. Methods Retrospective cohort study of women who presented to Panzi Hospital in 2006 requesting post-sexual violence care. Data was extracted and analyzed to describe the patterns of sexual violence. Results A total of 1,021 medical records were reviewed. A majority of attacks occurred in individual homes (56.5%, with the fields (18.4% and the forest (14.3% also being frequent locations of attack. In total, 58.9% of all attacks occurred at night. Of the four primary types of sexual violence, gang rape predominated (59.3% and rape Not Otherwise Specified (NOS was also common (21.5%. Sexual slavery was described by 4.9% of the survivors and a combination of gang rape and sexual slavery was described by 11.7%. The mean number of assailants per attack was 2.5 with a range of one to > 15. There were several demographic predictors for sexual slavery. Controlling for age, education level and occupation, a marital status of "single" increased the risk of sexual slavery (OR = 2.97, 95% CI = 1.12-7.85. Similarly, after controlling for other variables, age was a significant predictor of sexual slavery with older women being at a slightly reduced risk (OR = 0.96, 95% CI = 0.92-0.99. Women who experienced sexual slavery were 37 times more likely to have a resultant pregnancy in comparison to those who reported other types of sexual violence (OR = 37.50, 95% CI = 14.57-99.33. Conclusions Among sexual violence survivors presenting to Panzi Hospital in 2006, the majority of attacks occurred in women's own homes, often at night. This represents a pattern of violence that differs from other conflict settings and has important implications regarding protection strategies. Sexual violence in South Kivu was also marked with a

    Full Text Available Abstract Background In many developing countries, the majority of births are attended by traditional birth attendants, who lack formal training in neonatal resuscitation and other essential care required by the newly born infant. In these countries, the major causes of neonatal mortality are birth asphyxia, infection, and low-birth-weight/prematurity. Death from these causes is potentially modifiable using low-cost interventions, including neonatal resuscitation training. The purpose of this study was to evaluate the effect on perinatal mortality of training birth attendants in a rural area of the Democratic Republic of Congo (DRC using two established programs. Methods This study, a secondary analysis of DRC-specific data collected during a multi-country study, was conducted in two phases. The effect of training using the WHO Essential Newborn Care (ENC program was evaluated using an active baseline design, followed by a cluster randomized trial of training using an adaptation of a neonatal resuscitation program (NRP. The perinatal mortality rates before ENC, after ENC training, and after randomization to additional NRP training or continued care were compared. In addition, the influence of time following resuscitation training was investigated by examining change in perinatal mortality during sequential three-month increments following ENC training. Results More than two-thirds of deliveries were attended by traditional birth attendants and occurred in homes; these proportions decreased after ENC training. There was no apparent decline in perinatal mortality when the outcome of all deliveries prior to ENC training was compared to those after ENC but before NRP training. However, there was a gradual but significant decline in perinatal mortality during the year following ENC training (RR 0.73; 95% CI: 0.56-0.96, which was independently associated with time following training. The decline was attributable to a decline in early neonatal mortality

    Full Text Available Data collected during the 2012 Ebola virus disease (EVD epidemic in the Democratic Republic of the Congo were analysed for clinical signs, symptoms and case fatality of EVD caused by Bundibugyo virus (BDBV, establishment of differential diagnoses, description of medical treatment and evaluation of the quality of clinical documentation. In a quantitative observational prospective study, global epidemiological data from 52 patients (34 patients within the community, 18 patients treated in the Ebola Treatment Centre were entered anonymously into a database, subsequently matched and analysed. Relevant findings include an over-representation of females among community EVD cases (85.3% and of community EVD cases in the age group of 15-54 years (82.4%. All ETC patients had fever (55.6% of all 18 ETC patients during their hospital stay or self-reported fever (88.2% upon admission at some point of time during their illness. Major symptoms of ETC patients during hospital stay included asthenia (82.4%, anorexia (82.4%, myalgia (70.6%, sore throat/difficulty swallowing (70.6%, arthralgia (76.5% and nausea (70.6%. Gastrointestinal signs and symptoms (nausea, diarrhoea, vomiting (76.4% as well as general pain (94.1% were frequent in ETC patients. The median duration of EVD was 18 days, while the mean incubation period was 11.3 days. Differential diagnosis of EVD included malaria (28.3%, intestinal parasitosis (10.9%, and infectious syndrome (10.9%. There was also an important variation in clinical evolvement. Quality of documentation was adversely affected by the way patient file contents were transferred from inside to outside the high-risk zone, entailing a mean mismatch value of 27.3% between patient file contents inside vs. outside the high-risk zone. This study adds further description of EVD (frequently non-specific signs and symptoms, non frequent bleeding, a long incubation period, long duration of disease and emphasizes the need for improving

A cross-sectional study was carried out in University of Kinshasa, Kinshasa, Democratic Republic of Congo. Medical records of all students with malaria admitted to Centre de Santé Universitaire of University of Kinshasa from January 1, 2008, to April 30, 2008, were reviewed retrospectively. Results. The median age of the patients was 25.4 years (range: from 18 to 36 years. The majority of them were male (67.9%. Artemisinin-based combination treatments (ACTs was the most used self-prescribed antimalarial drugs. However, self-medication was associated with the ingestion of quinine in 19.9% of cases. No case of ingestion of artesunate/artemether in monotherapy was found. All the medicines taken were registered in DRC. In this series, self-prescribed antimalarial was very irrational in terms of dose and duration of treatment. Conclusion. This paper highlights self-medication by a group who should be aware of malaria treatment protocols. The level of self-prescribing quinine is relatively high among students and is disturbing for a molecule reserved for severe disease in Congolese health care policy in management of malaria.

    Little is known about human prehistory in the central African lowland tropical forest due to a paucity of archaeological evidence. Here we report results from our archaeological investigations of a late Holocene site in the northeast Congo Basin, with emphasis on a single skeleton from the rock shelter site of Matangai Turu Northwest, in the Ituri Forest, Democratic Republic of Congo. The skeleton dates from approximately 810 BP (1235 calibrated AD) and is associated with Later Stone Age lithics, animal bone and shell remains from wild taxa, fruit endocarps from forest trees, phytoliths from tropical forest plants, Late Iron Age ceramics, and a single iron artifact. Phytolith analysis indicates that the habitat was dense tropical forest, without evidence of domesticated food.

While most cases are asymptomatic, mansonelliasis can be associated with angioedema, arthralgia, swellings, pain in the scrotum or in serous cavities such as the pleura, the peritoneum, the pericardium, etc. Mansonelliasis can be really hard to treat, but it has been shown that an intensive treatment using albendazole can clear the parasite. Here we describe a case of a 16 months-old malnourished child with pneumonia due to M. perstans in the east of the Democratic Republic of Congo. Although our investigations confirmed M. perstans infection, this case shows that it is very difficult to come to a conclusive diagnosis.

    Full Text Available In the Democratic Republic of Congo, the incidence of sickle cell anemia (SCA is estimated to affect 30,000 to 40,000 neonates per year. However, there is paucity of data on acute clinical manifestations in sickle cell children. In these circumstances, it is difficult to develop a health care policy for an adequate management of sickle cell patients. This was a seven years’ retrospective study of children admitted with acute sickle cell crisis in the Department of Pediatrics in University Hospital of Kinshasa, Kinshasa, the Democratic Republic of Congo. A total of 108 patients were identified as having SCA. There were 56 (51% girls and 52 (49% boys. Median age was 10.5 years (range 1-24 years. No child was diagnosed by neonatal screening. The median age of diagnosis of sickle cell anemia was 90 months (range: 8-250 months. The median age at the first transfusion was 36 months (range 4-168. In this series, 61 (56.5% patients were eligible for hydroxyurea. However, this treatment was only performed in 4 (6.6% of them. Pain episodes, acute anemic crisis and severe infection represent respectively 38.2%, 34.3% and 21.9% of events. Altered sensorium and focal deficit were encountered occasionally and represented 3.4% of acute events. Acute renal manifestations, cholelithiasis and priapism were rarely reported, in this cohort. In Kinshasa, the care of patients suffering from sickle cell anemia is characterized by the delayed diagnosis and low detection of organ complications compared to reports of Western countries. This situation is due to resources deficiencies.

    Full Text Available Background: Maternal health care utilization continues to focus on the agenda of health care planners around the world, with high attention being paid to the developing countries. The devastating effect of maternal death at birth on the affected families is untold. This study examines the utilization of obstetric care in the Democratic Republic of Congo. Methods: We have used the nationally representative data from the 2007. Democratic Republic of Congo Demographic and Health Survey. Multilevel regression analysis has been applied to a nationally representative sample of 6,695 women, clustered around 299 communities in the country. Results: The results show that there are variations in the use of antenatal care and delivery care. Individual-level characteristics, such as women′s occupation and household wealth status are shown to be associated with the use of antenatal care. Uptake of facility-based delivery has been seen to be dependent on the household wealth status, women′s education, and partner′s education. The effect of the neighborhoods′ socioeconomic disadvantage on the use of antenatal care and facility-based delivery are the same. Women from highly socioeconomically disadvantaged communities, compared to their counterparts from less socioeconomically disadvantaged neighborhoods, are less likely to utilize both the antenatal services and healthcare facility for child delivery. The result of this study has shown that both individual and contextual socioeconomic status play an important role in obstetric care uptake. Conclusion: Thus, intervention aimed at improving the utilization of obstetrics care should target both the individual economic abilities of the women and that of their environment when considering the demand side.

    Full Text Available Hantaviruses are members of the Bunyaviridae family carried by small mammals and causing human hemorrhagic fevers worldwide. In Western Africa, where a variety of hemorrhagic fever viruses occurs, indigenous hantaviruses have been molecularly found in animal reservoirs such as rodents, shrews, and bats since 2006. To investigate the human contact to hantaviruses carried by these hosts and to assess the public health relevance of hantaviruses for humans living in the tropical rainforest regions of Western and Central Africa, we performed a cross-sectional seroprevalence study in the region of Taï National Park in Côte d´Ivoire and the Bandundu region near the Salonga National Park in the Democratic Republic of Congo. Serum samples were initially screened with enzyme-linked immunosorbent assays using nucleoproteins of several hantaviruses as diagnostic antigens. Positive results were confirmed by Western blotting and immunofluorescence testing.Seroprevalence rates of 3.9% (27/687 and 2.4% (7/295, respectively, were found in the investigated regions in Côte d´Ivoire and the Democratic Republic of Congo. In Côte d´Ivoire, this value was significantly higher than the seroprevalence rates previously reported from the neighboring country Guinea as well as from South Africa. Our study indicates an exposure of humans to hantaviruses in West and Central African tropical rainforest areas. In order to pinpoint the possible existence and frequency of clinical disease caused by hantaviruses in this region of the world, systematic investigations of patients with fever and renal or respiratory symptoms are required.

    2017-02-01

    Steganography has been proposed as a data hiding technique. As a derivation, quantum steganography based on quantum physics has also been proposed. In this paper, we extend the results in presented (Mihara, Phys. Lett. 379, 952 2015) and propose a multi-party quantum steganography technique that combines quantum error-correcting codes with entanglement. The proposed protocol shares an entangled state among n +1 parties and sends n secret messages, corresponding to the n parties, to the other party. With no knowledge of the other secret messages, the n parties can construct a stego message by cooperating with each other. Finally, we propose a protocol for sending qubits using the same technique.

    Although the United Nations General Assembly recognized in 2010 the right to safe and clean drinking water and sanitation as a human right that is essential to the full enjoyment of life and all other human rights, the contamination of water supplies with faecal pathogens is still a major and unsolved problem in many parts of the world. In this study, faecal indicator bacteria (FIB), including Escherichia coli (E. coli) and Enterococcus (ENT), were quantified over the period of June/July 2014 and June/July 2015 to assess the quality of hospital effluents (n = 3: H1, H2 and H3) and of rivers receiving wastewaters from the city of Kinshasa, Democratic Republic of Congo. The water and sediment samples from the river-receiving systems were collected in, upstream and downstream of the hospital outlet pipe (HOP) discharge. The analysis of E. coli and ENT in water and sediment suspension was performed using the cultural membrane filter method. The FIB characterization was performed for general E. coli, Enterococcus faecalis(E. faecalis) and human-specific Bacteroides by PCR using specific primers. The results revealed very high FIB concentration in the hospital effluent waters, with E. coli reaching the values of 4.2 × 10(5), 16.1 × 10(5) and 5.9 × 10(5) CFU 100 mL(-1), for the hospital effluents from H1, H2, and H3, respectively; and Enterococcus reaching the values of 2.3 × 10(4), 10.9 × 10(4) and 4.1 × 10(4) CFU 100 mL(-1), respectively. Interestingly, the FIB levels in the water and sediment samples from river-receiving systems are spatially and temporally highly variable and present in some samples with higher values than the hospital effluents. The PCR assays for human-specific Bacteroides HF183/HF134 further indicate that more than 98% of bacteria were from human origin. The results of this research therefore confirm the hypothesis of our previous studies, indicating that in developing countries (e.g., Democratic Republic of Congo and South India), the

    2009-02-01

    Full Text Available Abstract Background This study examines the potential of aid effectiveness to positively influence human resources for health in developing countries, based on research carried out in the Lao People's Democratic Republic (Lao PDR. Efforts to make aid more effective – as articulated in the 2005 Paris Declaration and recently reiterated in the 2008 Accra Agenda for Action – are becoming an increasingly prominent part of the development agenda. A common criticism, though, is that these discussions have limited impact at sector level. Human resources for health are characterized by a rich and complex network of interactions and influences – both across government and the donor community. This complexity provides a good prism through which to assess the potential of the aid effectiveness agenda to support health development and, conversely, possibilities to extend the impact of aid-effectiveness approaches to sector level. Methods The research adopted a case study approach using mixed research methods. It draws on a quantitative analysis of human resources for health in the Lao People's Democratic Republic, supplementing this with a documentary and policy analysis. Qualitative methods, including key informant interviews and observation, were also used. Results The research revealed a number pathways through which aid effectiveness is promoting an integrated, holistic response to a range of human resources for health challenges, and has identified further opportunities for stronger linkages. The pathways include: (1 efforts to improve governance and accountability, which are often central to the aid effectiveness agenda, and can be used as an entry point for reforming workforce planning and regulation; (2 financial management reforms, typically linked to provision of budget support, that open the way for greater transparency and better management of health monies and, ultimately, higher salaries and revenues for health facilities; (3 commitments

  19. Development of Democratic Processes in the People’s Republic of China: Prospects of Transformation of the Political Regime

    Directory of Open Access Journals (Sweden)

    Alexey Alexandrovich Semenov

    2016-04-01

    Full Text Available Rapid economic growth of the PRC has brought new challenges and promoted social transformation in Chinese society. China suffers profound changes involving fundamental principles of public relations. The political regime in China is in a changeable condition, and continues to transform. Some decisions of the Chinese government affect not only the economy and public administration, but also in some ways human rights and political changes. Chinese political regime takes on the pending social problems and begins to gently lift old political bans. There is development of processes which at least by the formal features can be attributed to be democratic or quasi-democratic. However, despite a number of political changes and improving of human rights situation in last decades, China is still an illiberal state. Moreover, the level of repression in China has increased in the last few years. All of these actions raise questions about the political future of China. The scale of the socio-economic changes that have occurred in the PRC is so significant, that the maintaining of the existing governance structure is not possible. Rapid economic growth reduced public discontent at the disregard to fundamental human rights. Yet the “economic miracle” is coming to an end, and the country desperately needs economic and political reforms. Lack of reforms or its incorrect implementation can put the existing system out of balance, which will lead to adverse effects not only in China but also in the world. Depending on the reforms we can assume several scenarios for further development of the PRC.

    Full Text Available Earth observation is an important source of information in areas that are too remote, too insecure or even both for traditional field surveys. A multi-scale analysis approach is developed to monitor the Kivu provinces in the Democratic Republic of the Congo (DRC to identify hot spots of mining activities and provide reliable information about the situation in and around two selected mining sites, Mumba-Bibatama and Bisie. The first is the test case for the approach and the detection of unknown mining sites, whereas the second acts as reference case since it is the largest and most well-known location for cassiterite extraction in eastern Congo. Thus it plays a key-role within the context of the conflicts in this region. Detailed multi-temporal analyses of very high-resolution (VHR satellite data demonstrates the capabilities of Geographic Object-Based Image Analysis (GEOBIA techniques for providing information about the situation during a mining ban announced by the Congolese President between September 2010 and March 2011. Although the opening of new surface patches can serve as an indication for activities in the area, the pure change between the two satellite images does not in itself produce confirming evidence. However, in combination with observations on the ground, it becomes evident that mining activities continued in Bisie during the ban, even though the production volume went down considerably.

  1. Dynamics of phytoestrogen, isoflavonoids, and its isolation from stems of Pueraria lobata (Willd. Ohwi growing in Democratic People's Republic of Korea

    2015-09-01

    Full Text Available Four isoflavonoids were isolated from stems of Pueraria lobata (Willd. Ohwi growing in Democratic People's Republic of Korea and identified as daidzein (1, genistin (2, daidzin (3, and puerarin (4, structures, which were elucidated by means of spectroscopic analysis. Isoflavonoids were isolated using silica gel chromatography and purified with organic solvents. Isoflavonoid contents in P. lobata were determined using reliable high-performance liquid chromatography. The results indicated that the contents of puerarin and genistin in the roots are higher than those in the stems (6.19% and 0.04% vs. 1.15% and 0.02%, whereas the stems have higher contents of daidzin and daidzein than the roots (3.17% and 0.06% vs. 1.72% and 0.05%. Accordingly, the root part of the plant is useful for the isolation of puerarin and the stem part for daidzin. This study suggests that the stem of P. lobata is useful as an alternative source of puerarin, daidzin, genistin, and daidzein. In addition, collection of the stem will not sacrifice the plant and thus is beneficial to the natural ecosystems.

    Paektu volcano (Changbaishan) is a rhyolitic caldera that straddles the border between the Democratic People’s Republic of Korea and China. Its most recent large eruption was the Millennium Eruption (ME; 23 km3 dense rock equivalent) circa 946 CE, which resulted in the release of copious magmatic volatiles (H2O, CO2, sulfur, and halogens). Accurate quantification of volatile yield and composition is critical in assessing volcanogenic climate impacts but is challenging, particularly for events before the satellite era. We use a geochemical technique to quantify volatile composition and upper bounds to yields for the ME by examining trends in incompatible trace and volatile element concentrations in crystal-hosted melt inclusions. We estimate that the ME could have emitted as much as 45 Tg of S to the atmosphere. This is greater than the quantity of S released by the 1815 eruption of Tambora, which contributed to the “year without a summer.” Our maximum gas yield estimates place the ME among the strongest emitters of climate-forcing gases in the Common Era. However, ice cores from Greenland record only a relatively weak sulfate signal attributed to the ME. We suggest that other factors came into play in minimizing the glaciochemical signature. This paradoxical case in which high S emissions do not result in a strong glacial sulfate signal may present a way forward in building more generalized models for interpreting which volcanic eruptions have produced large climate impacts.

    Physicochemical and ecotoxicological analyses have been performed to assess the quality of sediments receiving untreated hospital effluents from Indian and Democratic Republic of Congo (DRC) hospitals. The sediments were collected monthly and characterized for grain size, organic matter, total organic carbon, total carbon, nitrogen, phosphorus, toxic metals and ecotoxicity. The results highlight the high concentration of toxic metals from the Indian hospital effluent receiving systems, especially for Cr, Cu, As, Zn and Hg. On the other hand, the metal concentrations in the sediment receiving system from DRC are low (e.g. maximum Hg and Zn concentration were 0.46 and 48.84 mg kg(-1) respectively). Ostracods exposed to sediment samples H2 (September month sample) and H3 (June and September month samples) were found dead after 6d of exposure whereas the higher mortality rate for Congo sediments was 23% but was accompanied with 33 ± 7% of growth inhibition. The results of this study show the variation of sediment composition on toxic metal levels as well as toxicity related to both, the type of hospitals and the sampling period. Additionally, hospital effluent disposal practices at the study sites can lead to the pollution of water resources and may generate risks for aquatic organisms and human health.

    To examine the current partnerships to improve the childhood immunisation programme in the Democratic Peoples' Republic of Korea (DPRK) in the context of the political determinants of health equity. A literature search was conducted to identify public health collaborations with the DPRK government. Based on the amount of publicly accessible data and a shared approach in health system strengthening among the partners in immunisation programmes, the search focused on these partnerships. The efforts by WHO, UNICEF, GAVI and IVI with the DPRK government improved the delivery of childhood vaccines (e.g. pentavalent vaccines, inactivated polio vaccine, two-dose measles vaccine and Japanese encephalitis vaccine) and strengthened the DPRK health system by equipping health centres, and training all levels of public health personnel for VPD surveillance and immunisation service delivery. The VPD-focused programmatic activities in the DPRK have improved the delivery of childhood immunisation and have created dialogue and contact with the people of the DPRK. These efforts are likely to ameliorate the political isolation of the people of the DPRK and potentially improve global health equity. © 2016 The Authors.

    This paper demonstrates the feasibility of health services research in an unstable environment during the transition from crisis to development and its importance for future planning. Effectiveness and the cost of caesarean sections (CSs) were investigated in Bunia, a town affected by conflict and insecurity, in the Democratic Republic of the Congo (DRC) in 2008. The CS rate was 9.7 per cent of expected deliveries. All CSs in the study sample were emergency procedures. A humanitarian non-governmental organisation (NGO) hospital, offering free services, performed 75 per cent of all CSs. The estimated provider cost for CS in 2008 at this hospital was USD 103,514 (that is, USD 144 per CS). With a cost of between USD 3.8 and 9.2 per year of health adjusted life expectancy (HALE) gained, CSs at the NGO hospital were very cost-effective. The estimates give an indication of funding requirements to maintain adequate access to CS after the departure of the humanitarian organisation.

  6. Lesula: a new species of Cercopithecus monkey endemic to the Democratic Republic of Congo and implications for conservation of Congo's central basin.

    Directory of Open Access Journals (Sweden)

    John A Hart

    Full Text Available In June 2007, a previously undescribed monkey known locally as "lesula" was found in the forests of the middle Lomami Basin in central Democratic Republic of Congo (DRC. We describe this new species as Cercopithecus lomamiensis sp. nov., and provide data on its distribution, morphology, genetics, ecology and behavior. C. lomamiensis is restricted to the lowland rain forests of central DRC between the middle Lomami and the upper Tshuapa Rivers. Morphological and molecular data confirm that C. lomamiensis is distinct from its nearest congener, C. hamlyni, from which it is separated geographically by both the Congo (Lualaba and the Lomami Rivers. C. lomamiensis, like C. hamlyni, is semi-terrestrial with a diet containing terrestrial herbaceous vegetation. The discovery of C. lomamiensis highlights the biogeographic significance and importance for conservation of central Congo's interfluvial TL2 region, defined from the upper Tshuapa River through the Lomami Basin to the Congo (Lualaba River. The TL2 region has been found to contain a high diversity of anthropoid primates including three forms, in addition to C. lomamiensis, that are endemic to the area. We recommend the common name, lesula, for this new species, as it is the vernacular name used over most of its known range.

    The Democratic Republic of Congo (DRC) remains an all-too-potent reminder of how war, human rights violations and their related health and economic impacts can devastate a society. The last decade has seen the use of rape as a weapon of war in the DRC, where rebels and soldiers subject women and girls to brutalising attacks, rape, torture and mutilation. Survivors of sexual and gender-based violence (SGBV) are often further traumatised by infections, disease, poverty, stigma and social isolation. Substantial evidence exists showing an association between social determinants (e.g., poverty, stress and trauma, stigma, lack of access to health care) and health; however, limited research has been conducted to elucidate these relationships or to develop and test interventions to change social determinants of health, especially in conflict and post-conflict settings such as the DRC. The purpose of this article is to present a Congolese-US community-academic research partnership to obtain evidence to develop and implement a sustainable intervention to begin to address the social determinants of health, including poverty and traumatic stress for survivors of SGBV and their families in the South Kivu province of eastern DRC.

    Full-length genomes were characterized for two samples, 02CD-LBR024 from the Democratic Republic of Congo (DRC) and 04FR-CD-KZS from France, that formed a separate subcluster with a previously characterized env subtype E isolate from DRC with a recombinant structure different from CRF01-AE. Since the three viruses are clearly epidemiologically unlinked and share the same complex recombinant structure, they represent a circulating recombinant form, designated as CRF27-cpx. The recombination pattern involves six different HIV-1 subtypes (A, E, G, H, J, and K) and a small unclassified fragment. The genetic distances are relatively high, indicating that CRF27-cpx evolved over a long time. Their prevalence is low (0.75%) and remained stable over time in the DRC. The existence of the 04FR.CD.KZS virus, in a patient who recently seroconverted in France, confirmed that these strains now circulate outside the DRC. Continuous monitoring of HIV-1 strains thus remains important to allow early identification of the introduction of new variants.

    Currently, four species of the lacertid lizard genus Adolfus are known from Central and East Africa. We sequenced up to 2,825 bp of two mitochondrial (16S and cyt b) and two nuclear (c-mos and RAG1) genes from 41 samples of Adolfus (representing every species), two species each of Gastropholis and Holaspis, and in separate analyses combined this data with GenBank sequences of all other Eremiadini genera and four Lacertini outgroups. Data from DNA sequences were analyzed with maximum parsimony (PAUP), maximum-likelihood (RAxML) and Bayesian inference (MrBayes) criteria. Results demonstrated that Adolfus is not monophyletic: A. africanus (type species), A. alleni and A. jacksoni are sister taxa, whereas A. vauereselli and a new species from the Itombwe Plateau of Democratic Republic of the Congo are in a separate lineage. Holaspis and Gastropholis were recovered in separate clades. Based on this molecular data, relatively substantial sequence divergence and multiple morphological differences, we describe a new genus of lacertid for the lineage including A. vauereselli and the new Itombwe species. The recognition of this new, endemic genus underscores the conservation importance of the Albertine Rift, especially the Itombwe Plateau, a unique region that is severely threatened by unchecked deforestation, mining and poaching.

    Conditions in the Democratic Republic of the Congo provide an ideal environment for leptospirosis and plague, both of which can cause severe pulmonary manifestations. In December 2004, an outbreak of lethal pneumonia occurred in a local mining camp, affecting 130 persons and killing 57 of them. Clinical signs, fast disease spread, and initial laboratory investigations suggested pneumonic plague. While leptospirosis had not recently been described in the region, it was considered as a differential diagnosis. Anti-Leptospira antibodies were detected by microscopic agglutination test (MAT). A confirmed case of leptospirosis was defined as having consistent clinical signs and any one of the following: seroconversion or four-fold increase in MAT titre for paired serum samples, or a MAT titre ≥ 1:400 for acute-phase serum samples. Twenty-nine of the 54 patients or convalescents tested for leptospirosis were seropositive. Two cases showed a confirmed infection for both plague and leptospirosis. While evidence supports the plague nature of this outbreak, the results suggest that some of the suspected plague cases might be due to leptospirosis. In any case, this diagnosis will have to be evoked in the future if a similar outbreak occurs in this region of Africa.

    Effective HIV prevention programs for people living with HIV/AIDS (PLWH) are important to reduce new infections and to ensure PLWH remain healthy. This paper describes the systematic adaptation of a U.S.-developed Evidence Based Intervention (EBI) using the Centers for Disease Control and Prevention (CDC) Map of Adaption Process for use at a Pediatric Hospital in Kinshasa, Democratic Republic of the Congo (DRC). The adapted intervention, Supporting Youth and Motivating Positive Action or SYMPA, a six-session risk reduction intervention targeted for youth living with HIV/AIDS (YLWH) in Kinshasa was adapted from the Healthy Living Project and guided by the Social Action Theory. This paper describes the process of implementing the first four steps of the ADAPT framework (Assess, Select, Prepare, and Pilot). Our study has shown that an EBI developed and implemented in the U.S. can be adapted successfully for a different target population in a low-resource context through an iterative process following the CDC ADAPT framework. This process included reviewing existing literature, adapting and adding components, and focusing on increasing staff capacity. This paper provides a rare, detailed description of the adaptation process and may aid organizations seeking to adapt and implement HIV prevention EBIs in sub-Saharan Africa and beyond.

    Socio-cultural and economic factors constitute real barriers for uptake of screening and treatment of Human African Trypanosomiasis (HAT) in the Democratic Republic of Congo (DRC). Better understanding and addressing these barriers may enhance the effectiveness of HAT control. We performed a qualitative study consisting of semi-structured interviews and focus group discussions in the Bandundu and Kasaï Oriental provinces, two provinces lagging behind in the HAT elimination effort. Our study population included current and former HAT patients, as well as healthcare providers and program managers of the national HAT control program. All interviews and discussions were voice recorded on a digital device and data were analysed with the ATLAS.ti software. Health workers and community members quoted a number of prohibitions that have to be respected for six months after HAT treatment: no work, no sexual intercourse, no hot food, not walking in the sun. Violating these restrictions is believed to cause serious, and sometimes deadly, complications. These strong prohibitions are well-known by the community and lead some people to avoid HAT screening campaigns, for fear of having to observe such taboos in case of diagnosis. The restrictions originally aimed to mitigate the severe adverse effects of the melarsoprol regimen, but are not evidence-based and became obsolete with the new safer drugs. Correct health information regarding HAT treatment is essential. Health providers should address the perspective of the community in a constant dialogue to keep abreast of unintended transformations of meaning.

    Full Text Available Background/Aim. Wars of the nineties in former Yugoslavia, Somalia, Rwanda imposed new tasks to the United Nations (UN forces, such as providing humanitarian aid, protection of civilians, peacekeeping, and in many instances providing armed enforcement of peace. The aim of this study was an observational analysis of Serbian participation in the UNs Mission in the Democratic Republic of Congo with the emphasis on stress and coping techniques. Methods. Serbian contribution in this mission dates back to April 2003 till the present days with a military contingent consisting of six members as a part of Air Medical Evacuation Team. The observed stressogenous factors acted before arrival to the mission area and in the mission area. In this paper we analysed ways to overcome them. Results. The productive ways of overwhelming stress used in this mission were: honesty and openness in interpersonal communications, dedication to work, maintaining discipline and order, strict following of appropriate regime of work, diet, rest and recreation; regular communication with family and organizing and participation in various social, cultural and sports manifestations. Conclusion. This analysis indicates that out of all the observed factors, the most important is appropriate selection of personnel.

    In this study object-based image analysis (OBIA) techniques were applied to assess land cover changes related to mineral extraction in a conflict-affected area of the eastern Democratic Republic of the Congo (DRC) over a period of five years based on very high resolution (VHR) satellite data of different sensors. Object-based approaches explicitly consider spatio-temporal aspects which allow extracting important information to document mining activities. The use of remote sensing data as an independent, up-to-date and reliable data source provided hints on the general development of the mining sector in relation to socio-economic and political decisions. While in early 2010, the situation was still characterised by an intensification of mineral extraction, a mining ban between autumn 2010 and spring 2011 marked the starting point for a continuous decrease of mining activities. The latter can be substantiated through a decrease in the extend of the mining area as well as of the number of dwellings in the nearby settlement. A following demilitarisation and the mentioned need for accountability with respect to the origin of certain minerals led to organised, more industrialized exploitation. This development is likewise visible on satellite imagery as typical clearings within forested areas. The results of the continuous monitoring in turn facilitate non-governmental organisations (NGOs) to further foster the mentioned establishment of responsible supply chains by the mining industry throughout the entire period of investigation.

    This article sets medico legal light on torture of three former child soldiers by comparing torture methods, consequences of torture and medical observations. It is focused on these child soldiers as representatives of the many abuses of children as soldiers in armed groups. The three persons were child soldiers during 12 years in The Democratic Republic of Congo (DRC) as members of three different armed groups. They were exposed to armed conflict events, experienced torture, and participated in atrocities, sexual abuse and traditional rituals during their role in armed conflict. They were psychologically distressed with unhealthy physical and mental states. The principles for working with child soldiers are described. The model addresses basic items: The confluence of the dimensions of the items will determine the specifics of medico legal evidence of torture in child soldiers, taking into consideration inputs that are required at the macro, community and individual levels. A primary goal is to prevent violence from occurring in child soldiers. Thus, much more deliberate effort is made to address the underlying causes of recruitment of children in armed groups in DRC and to invest more resources in conflict resolution before there is an outbreak of violence. Peace education tends to be introduced too late and does little to alleviate the use of children in armed conflict in DRC.

    Mining natural resources serve fundamental societal needs or commercial interests, but it may well turn into a driver of violence and regional instability. In this study, very high resolution (VHR) optical stereo satellite data are analysed to monitor processes and changes in one of the largest artisanal and small-scale mining sites in the Democratic Republic of the Congo, which is among the world's wealthiest countries in exploitable minerals To identify the subtle structural changes, the applied methodological framework employs object-based change detection (OBCD) based on optical VHR data and generated digital surface models (DSM). Results prove the DSM-based change detection approach enhances the assessment gained from sole 2D analyses by providing valuable information about changes in surface structure or volume. Land cover changes as analysed by OBCD reveal an increase in bare soil area by a rate of 47% between April 2010 and September 2010, followed by a significant decrease of 47.5% until March 2015. Beyond that, DSM differencing enabled the characterisation of small-scale features such as pits and excavations. The presented Earth observation (EO)-based monitoring of mineral exploitation aims at a better understanding of the relations between resource extraction and conflict, and thus providing relevant information for potential mitigation strategies and peace building.

    Full Text Available Plasmodiums are protozoa that may infect various hosts. Only five species are now recognized as naturally parasitizing humans: Plasmodium falciparum, Plasmodium vivax, Plasmodium malariae, Plasmodium ovale and Plasmodium knowlesi. This fifth species, P. knowlesi, previously identified as naturally parasitizing the monkey Macaca fascicularis, has been microscopically confused for a long time with P. malariae or P. falciparum and it was not possible to correctly differentiate them until the advent of molecular biology. To date, natural human infections with P. knowlesi only occur in Southeast Asia and a similar phenomenon of natural transmission of simian plasmodium to humans has not been reported elsewhere. This study was conducted to investigate a possible transmission of African small monkey's plasmodium to humans in populations living near the rainforest of the Democratic Republic of Congo (DRC where several species of non-human primates are living. Two successive real-time PCRs were identified in the literature and used in combination for purpose. Only P. falciparum was found in this study. However, studies with larger samples and with more advanced techniques should be conducted.

  19. Observed Differences in the Human Footprint and Forest Fragmentation in the Primary Forest Area of the Democratic Republic of Congo: A Remote Sensing Study for 2000-2010

    Conflict in the Democratic Republic of Congo (DRC) and neighboring countries has caused the displacement of people internally and internationally sometimes leading to drastic changes in the impact that traditional slash and burn shifting cultivation has on the forest ecosystem. In other areas, the lack of infrastructure and governance has isolated and protected areas of core forest from large scale exploitation. Observing specific patterns of forest fragmentation caused either by the expansion of existing rural complex areas or of isolated forest perforations has allowed us to track the differential growth of the human footprint throughout forested area of the country during the period 2000-2010. Our methodological approach involved the development of a model of shifting cultivation and forest fragmentation in which spatial rules applied morphological image processing to the Forets d'Afrique Central Evaluee par Teledetection (FACET) product. The result is a disaggregated classification of the primary forest into patch, edge, perforated, fragmented and core forest subtypes which we subsequently re-aggregated into homogenous anthropogenic macro-areas of rural complex and isolated forest perforations. We tracked how subsequent forest loss observed in 2005 and 2010 grew or shrunk these areas, presumably with differential impacts on the forest ecosystem. Using this approach we were able to map forest degradation by contextualizing the contribution of forest loss to change in different types of areas, highlighting how it can be greatly underestimated by a non contextualized per-pixel assessment of forest cover loss.

    Anaemia is associated with adverse outcomes including early death in the first year of antiretroviral therapy (ART). This study reports on the factors associated with persistent anaemia among HIV-infected patients initiating ART in the Democratic Republic of Congo (DR Congo). We conducted a retrospective cohort study and analyzed data from patients receiving HIV care between January 2004 and December 2012 at two major hospitals in Goma, DR Congo. Haemoglobin concentrations of all patients on ART regimen were obtained prior to and within one year of ART initiation. A logistic regression model was used to identify the predictors of persistent anaemia after 12 months of ART. Of 756 patients, 69% of patients were anaemic (IC95%: 65.7-72.3) at baseline. After 12 months of follow up, there was a 1.2 g/dl average increase of haemoglobin concentration (P anaemia at the beginning, 33% (147/445) had the condition resolved. Among patients with anaemia at ART initiation, those who did not receive cotrimoxazole prophylaxis before starting ART(AOR 3.89; 95% CI 2.09-7.25; P anaemia. More than two thirds of patients had anaemia at baseline. The AZT-containing regimen and absence of cotrimoxazole prophylaxis before starting ART were associated with persistent anaemia 12 months, after initiation of treatment. Considering the large proportion of patients with persistence of anaemia at 12 months, we suggest that it is necessary to conduct a large study to assess anaemia among HIV-infected patients in Goma.

    Modern remote sensing techniques enable the mapping and monitoring of aboveground biomass (AGB) carbon stocks without relying on extensive in situ measurements. The Democratic Republic of the Congo (DRC) is among the countries where a national forest inventory (NFI) has yet to be established due to a lack of infrastructure and political instability. We demonstrate a method for producing national-scale gross AGB loss estimates and quantifying uncertainty of the estimates using remotely sensed-derived forest cover loss and biomass carbon density data. Forest cover type and loss were characterized using published Landsat-based data sets and related to LIDAR-derived biomass data from the Geoscience Laser Altimeter System (GLAS). We produced two gross AGB loss estimates for the DRC for the last decade (2000-2010): a conservative estimate accounting for classification errors in the 60-m resolution FACET forest cover change product, and a maximal estimate that also took into consideration omitted change at the 30m spatial resolution. Omitted disturbances were largely related to smallholder agriculture, the detection of which is scale-dependent. The use of LIDAR data as a substitute for NFI data to estimate AGB loss based on Landsat-derived activity data was demonstrated. Comparisons of our forest cover loss and AGB estimates with published studies raise the issue of scale in forest cover change mapping and its impact on carbon stock change estimation using remotely sensed data.

    Objectives. We evaluated changes in social capital following group-based cognitive processing therapy (CPT) for female survivors of sexual violence. Methods. We compared CPT with individual support in a cluster-randomized trial in villages in South Kivu province, Democratic Republic of the Congo. Local psychosocial assistants delivered the interventions from April through July 2011. We evaluated differences between CPT and individual support conditions for structural social capital (i.e., time spent with nonkin social network, group membership and participation, and the size of financial and instrumental support networks) and emotional support seeking. We analyzed intervention effects with longitudinal random effects models. Results. We obtained small to medium effect size differences for 2 study outcomes. Women in the CPT villages increased group membership and participation at 6-month follow-up and emotional support seeking after the intervention compared with women in the individual support villages. Conclusions. Results support the efficacy of group CPT to increase dimensions of social capital among survivors of sexual violence in a low-income conflict-affected context. PMID:25033113

    In the field of development cooperation, interest in systems thinking and complex systems theories as a methodological approach is increasingly recognised. And so it is in health systems research, which informs health development aid interventions. However, practical applications remain scarce to date. The objective of this article is to contribute to the body of knowledge by presenting the tools inspired by systems thinking and complexity theories and methodological lessons learned from their application. These tools were used in a case study. Detailed results of this study are in process for publication in additional articles. Applying a complexity 'lens', the subject of the case study is the role of long-term international technical assistance in supporting health administration reform at the provincial level in the Democratic Republic of Congo. The Methods section presents the guiding principles of systems thinking and complex systems, their relevance and implication for the subject under study, and the existing tools associated with those theories which inspired us in the design of the data collection and analysis process. The tools and their application processes are presented in the results section, and followed in the discussion section by the critical analysis of their innovative potential and emergent challenges. The overall methodology provides a coherent whole, each tool bringing a different and complementary perspective on the system.

    The U.S. Geological Survey (USGS) analyzes mineral and metal supply chains to identify and describe major components of mineral and metal material flows from ore extraction, through intermediate forms, to a final product. Supply chain analyses may be used (1) to identify risks to the United States associated with the supply of critical and strategic minerals and metals and (2) to provide greater supply chain transparency so that policymakers have the fact-based information needed to formulate public policy. This fact sheet focuses on the post-mining/pre-consumer-product part of the tantalum supply chain. The USGS National Minerals Information Center (NMIC) has been asked by governmental and non-governmental organizations to provide information about tantalum, tin, tungsten, and gold (collectively known as “3TG minerals”) processing facilities worldwide in response to U.S. legislation aimed at identifying and removing the supply chain links between the trade in these minerals and civil unrest in the Democratic Republic of the Congo and adjacent countries.

    Kinshasa, the capital of the Democratic Republic of the Congo, has been a perennial malarious area and has grown almost 14 times from 380,000 people in 1960 to 5,293,000 in 2003. The most complete information on malaria prevalence in Kinshasa was first acquired in 1981-1983. Blood smears were obtained from 25,135 children (ages 5-15 years) from 245 schools in 16 of 24 zones. The mean Plasmodium falciparum parasite rate was 17%; the parasite rate was similar for both sexes and was higher (P schools from selected health zones. A mean parasite rate of 34% was found among school children 5-9 years old. The parasite rate varied from 14% (central urban zone) to 65% (peri urban zone). Plasmodium falciparum was not the only species found, but accounted for more than 97% of the infections. Malaria incidence may have increased in Kinshasa during the last two decades due to difficulties in provision of control and prevention measures. Along with deployment of insecticide-treated bed nets and improved patient management, currently ongoing, other measures that could impact the disease are being considered, including vector control, water management, and proper urban planning.

    The future of the HIV/AIDS epidemic in the Democratic Republic of Congo will depend on the behavior that teenagers and young adults are likely to adopt. Documenting teenagers and young adults behavior can help design effective interventions. The premarital sexual activity of 13,091 teenagers and young adults aged 15-24 years was examined. Logistic regression models were used to identify the correlates of ever had sex and recent sex. Ever had sex and recent sex were associated with older individuals, males, school dropouts, those addicted to alcohol and drug use, those living alone or with friends, those involved in an income generating activity, those with low capacity to resist sex, those with low socio-economic status and those living in permissive milieu. Controlling access to alcohol and drugs, teaching teenagers skills to resist sex, getting schools involved in teaching values of abstinence and delayed sex, could impact the age at first sex and trigger the adoption of lower risk behavior.

    The U.S. Geological Survey (USGS) analyzes supply chains to identify and define major components of mineral and material flows from ore extraction, through intermediate forms, to a final product. Two major reasons necessitate these analyses: (1) to identify risks associated with the supply of critical and strategic minerals to the United States and (2) to provide greater supply chain transparency so that policymakers have the information necessary to ensure domestic legislation compliance. This fact sheet focuses on the latter. The USGS National Minerals Information Center has been asked by governmental and non-governmental organizations to provide information on tin, tantalum, tungsten, and gold (collectively known as “3TG minerals”) processing facilities worldwide in response to U.S. legislation aimed at removing the link between the trade in these minerals and civil unrest in the Democratic Republic of the Congo. Post beneficiation processing plants (smelters and refineries) of 3TG mineral ores and concentrates were identified by company and industry association representatives as being the link in the 3TG mineral supply chain through which these minerals can be traced to their source of origin (mine); determining the point of origin is critical to establishing a transparent conflict mineral supply chain. This fact sheet, the first in a series of 3TG mineral fact sheets, focuses on the tungsten supply chain by listing plants that consume tungsten concentrates to produce ammonium paratungstate and ferrotungsten worldwide.

    Using entanglement of assistance, we establish a general polygamy inequality of multi-party entanglement in arbitrary dimensional quantum systems. For multi-party closed quantum systems, we relate our result with the monogamy of entanglement to show that the entropy of entanglement is an universal entanglement measure that bounds both monogamy and polygamy of multi-party quantum entanglement.

    Full Text Available The only available vaccine that could be potentially beneficial against mycobacterial diseases contains live attenuated bovine tuberculosis bacillus (Mycobacterium bovis also called Bacillus Calmette-Guérin (BCG. Even though the BCG vaccine is still widely used, results on its effectiveness in preventing mycobacterial diseases are partially contradictory, especially regarding Buruli Ulcer Disease (BUD. The aim of this case-control study is to evaluate the possible protective effect of BCG vaccination on BUD.The present study was performed in three different countries and sites where BUD is endemic: in the Democratic Republic of the Congo, Ghana, and Togo from 2010 through 2013. The large study population was comprised of 401 cases with laboratory confirmed BUD and 826 controls, mostly family members or neighbors.After stratification by the three countries, two sexes and four age groups, no significant correlation was found between the presence of BCG scar and BUD status of individuals. Multivariate analysis has shown that the independent variables country (p = 0.31, sex (p = 0.24, age (p = 0.96, and presence of a BCG scar (p = 0.07 did not significantly influence the development of BUD category I or category II/III. Furthermore, the status of BCG vaccination was also not significantly related to duration of BUD or time to healing of lesions.In our study, we did not observe significant evidence of a protective effect of routine BCG vaccination on the risk of developing either BUD or severe forms of BUD. Since accurate data on BCG strains used in these three countries were not available, no final conclusion can be drawn on the effectiveness of BCG strain in protecting against BUD. As has been suggested for tuberculosis and leprosy, well-designed prospective studies on different existing BCG vaccine strains are needed also for BUD.

    Household water treatment can improve the microbiological quality of drinking water and may prevent diarrheal diseases. However, current methods of treating water at home have certain shortcomings, and there is evidence of bias in the reported health impact of the intervention in open trial designs. We undertook a randomised, double-blinded, placebo-controlled trial among 240 households (1,144 persons) in rural Democratic Republic of Congo to assess the field performance, use and effectiveness of a novel filtration device in preventing diarrhea. Households were followed up monthly for 12 months. Filters and placebos were monitored for longevity and for microbiological performance by comparing thermotolerant coliform (TTC) levels in influent and effluent water samples. Mean longitudinal prevalence of diarrhea was estimated among participants of all ages. Compliance was assessed through self-reported use and presence of water in the top vessel of the device at the time of visit. Over the 12-month follow-up period, data were collected for 11,236 person-weeks of observation (81.8% total possible). After adjusting for clustering within the household, the longitudinal prevalence ratio of diarrhoea was 0.85 (95% confidence interval: 0.61-1.20). The filters achieved a 2.98 log reduction in TTC levels while, for reasons that are unclear, the placebos achieved a 1.05 log reduction (pwater the previous day. The filter maintained a constant flow rate over time, though 12.4% of filters were damaged during the course of the study. While the filter was effective in improving water quality, our results provide little evidence that it was protective against diarrhea. The moderate reduction observed nevertheless supports the need for larger studies that measure impact against a neutral placebo. Current Controlled Trials ISRCTN03844341.

    Full Text Available Introduction: Chikungunya is a vector-borne disease transmitted to humans by Aedes mosquitoes, which are widespread in the Lao People’s Democratic Republic. However, chikungunya virus (CHIKV had not been detected in the country before outbreaks reported in July 2012. The first outbreaks were detected through health care worker event-based surveillance. Methods: The case definition for the outbreaks was defined as a person with acute onset of fever (> 38 °C and severe arthralgia (joint pain or arthritis from 1 May 2012 in Champassak Province. Rapid response teams conducted active case finding, performed an environmental assessment including an entomological survey and implemented control measures. Descriptive analysis was undertaken in Microsoft Excel. Results: There were 197 cases (attack rate 3.4% of suspected chikungunya reported from 10 villages in Moonlapamok and Khong Districts of Champassak Province. All age groups (age range: seven months–74 years were affected with slightly more female (56% than male cases. Thirty-one per cent (16 of 52 of serum samples tested positive for CHIKV by polymerase chain reaction. The environmental assessment found poor water storage practices and high entomological indices. Discussion: These outbreaks show the effectiveness of health care worker event-based surveillance and the importance of sharing of information across borders for detecting emerging diseases. Public health education is an important measure to prevent epidemics of chikungunya. Information about chikungunya should be supplied to health care workers in the region so they are alert to the potential spread and are able to implement control measures for this disease.

    Pandemic influenza viruses can emerge through continuous evolution and the acquisition of specific mutations or through reassortment. This study assessed the pandemic potential of H5N1 viruses isolated from poultry outbreaks occurring from July 2006 to September 2008 in the Lao People's Democratic Republic (PDR). We analyzed 29 viruses isolated from chickens and ducks and two from fatal human cases in 2007. Prior to 2008, all H5N1 isolates in Lao PDR were from clade 2.3.4; however, clade 2.3.2 was introduced in September 2008. Of greatest concern was the circulation of three isolates that showed reduced sensitivity to the neuraminidase (NA) inhibitor oseltamivir in an enzyme inhibition assay, each with different NA mutations – V116A, I222L and K150N, and a previously unreported S246N mutation. In addition, six isolates had an S31N mutation in the M2 protein, which conferred resistance to amantadine not previously reported in clade 2.3.4 viruses. Two H5N1 reassortants were isolated whose polymerase genes, PB1 and PB2, were homologous to those of Eurasian viruses giving rise to a novel H5N1 genotype, genotype P. All H5N1 viruses retained avian-like receptor specificity, but four had altered affinities for α2,3-linked sialic acid. This study shows that, in a genetically similar population of H5N1 viruses in Lao PDR, mutants emerged with natural resistance to antivirals and altered affinities for α2,3-linked sialic acids, together with reassortants with polymerase genes homologous to Eurasian viruses. These changes may contribute to the emergence of a pandemic influenza strain and are critical in devising surveillance strategies. PMID:20016036

    Democratic Republic of Congo (DRC), a particular form of juvenile delinquency and insecurity intensifies in the city of Kinshasa. This is the phenomenon Kuluna. It is organized gangs equipped with machetes and other weapons. The main objective of this study is to know the phenomenon Kuluna and describe the upper limb injuries caused by machetes, while insisting on the specifics of the management of these lesions in our communities. This retrospective descriptive study examines 14 cases of wounds of the hand and forearm due to stab phenomenon Kuluna, in Kinshasa. It covers the period from 1 November 2010 to 1 November 2013. Among the 14 patients with lesions in the hand and forearm admitted and treated at the Unit of Plastic Reconstructive and Aesthetic Surgery, Hand Surgery and Burns, University Clinics of Kinshasa to attacks due to the phenomenon Kuluna. We have 11 men and 3 women. The average age was 33, 5 years (extremes of 21 and 56 years). The right upper limb is reached that the left upper limb, respectively 12 patients and 2 patients. The lesions are localized to the wrist in the majority of cases (10 patients) in the palm of hand and in 3 patients in the fingers in 1 patient. The palmar surface is reached (10 cases) and the dorsal (4 cases). Zone 5 of the International Classification of flexor and Zone 8 topographic classification extensors at hand are the predilection sites of lesions respectively the palmar surface (6 out of 10) and the dorsal (2 case 4). The median nerve at the wrist is cut in half the cases. On bone lesions localized to the forearm, we observed a high incidence of fracture of the ulna (62.5%). The treatment begins with the stabilization of bone pieces, gestures revascularization and nerve sutures and suture tendon and finally skin coverage. Rehabilitation was mandatory, she supervises the actions of repair and it continues until the recovery of function.

    Full Text Available It remains to be seen whether the past few months will mark a genuine turning point in the conflict in eastern Democratic Republic of Congo (DRC, as the rebel faction March 23 Movement (M23 announced the end of its 20-month insurgency against the government on 5 November 2013. News of the rebel group’s surrender following its political and military defeat signals an important moment of hope and renewed prospects of peace and stability in a region prone to protracted armed conflict. However, long-term stability in the country and in the region will require a multi-faceted process consisting of comprehensive accountability for human rights violations that have been committed by all parties to the conflict. In this article, I will first lay out the historical context of the fighting and the root causes of conflict present long before M23’s entrance onto the scene as a splintered rebel faction so as to understand M23’s place within the country’s history of protracted violence. Next, I will explain the violations of international humanitarian and human rights law committed by all possible parties, including rebel and government groups, as well as individual criminal responsibility and corporate liability. Lastly, I will chart the pathways of criminal and social accountability at various levels of international and domestic justice systems to see how the DRC may continue to build long-term local stability in the eastern parts of the country by addressing the question of accountability for international crimes. This brief analysis aims to provide a broader understanding of a complex conflict beyond the defeat and disarmament of M23, albeit a key group in a region of contentious cross-border conflict.

    Globally, an estimated 300,000 children under the age of 18 participate in combat situations; those in armed groups in particular suffer prolonged exposure to psychological and physical abuse. The Lord's Resistance Army (LRA) is a rebel movement known for its widespread conscription of children; yet little is known about this process once the group moved beyond northern Uganda. In this paper, we describe the processes related to abduction and indoctrination of youth by the LRA in northeastern Democratic Republic of the Congo ( DRC). In-depth interviews were conducted with formerly abducted children, their family members, community leaders, and service providers (total n = 34) in four communities in LRA-affected areas of northeastern DRC. Inductive coding of transcripts was undertaken to identify salient themes. Informants articulated a range of practices by the LRA to exert high levels of control over new recruits, including strict social isolation from recent abductees; control of communication; promoting new identity formation; and compelling children to act out strictly defined gendered roles. Witchcraft and secrecy are used to intimidate recruits and to magnify perception of the group's power. These methods promote de-identification with one's civilian and family life; and eventually the assimilation of a new language and identity. Indoctrination of newly abducted children into the LRA occurs via a complex system of control. This study provides one of the first detailed explorations of social and psychological mechanisms through which this is achieved, and focuses particularly on the gendered differences in the indoctrination process. Results support past findings that the LRA is a strategic and well-organized organization in its approach to enlisting child soldiers. Understanding some of the ways in which the LRA controls its recruits and the psychological impact of indoctrination enables reintegration programs to more effectively address these issues

    The child mortality rate is a good indicator of development. High levels of infectious diseases and high child mortality make the Democratic Republic of Congo (DRC) one of the most challenging environments for health development in Sub-Saharan Africa (SSA). Recent conflicts in the eastern part of the country and bad governance have compounded the problem. This study aimed to examine province-level geographic variation in under-five mortality (U5M), accounting for individual- and household-level risk factors including environmental factors such as conflict. Our analysis used the nationally representative cross-sectional household sample of 8,992 children under five in the 2007 DRC Demographic and Health Survey. In the survey year, 1,005 deaths among this group were observed. Information on U5M was aggregated to the 11 provinces, and a Bayesian geo-additive discrete-time survival mixed model was used to map the geographic distribution of under-five mortality rates (U5MRs) at the province level, accounting for observable and unobservable risk factors. The overall U5MR was 159 per 1,000 live births. Significant associations with risk of U5M were found for geographic patterns in rates of U5M in the DRC and shows the potential role of individual child, household and environmental factors, which are unexplained by the ongoing conflict. The displacement of mothers to safer areas may explain the lower U5MR observed at the epicentre of the conflict in North Kivu, compared with rates in conflict-free areas. Overall, the U5M maps point to a lack of progress towards the Millennium Development Goal of reducing U5M by half by 2015.

    Rapid diagnostic tests (RDTs) are widely used for malaria diagnosis, but lack of quality control at point of care restricts trust in test results. Prototype positive control wells (PCW) containing recombinant malaria antigens have been developed to identify poor-quality RDT lots. This study assessed community and facility health workers' (HW) ability to use PCWs to detect degraded RDTs, the impact of PCW availability on RDT use and prescribing, and preferred strategies for implementation in Lao People's Democratic Republic (Laos) and Uganda. A total of 557 HWs participated in Laos (267) and Uganda (290). After training, most (88% to ≥ 99%) participants correctly performed the six key individual PCW steps; performance was generally maintained during the 6-month study period. Nearly all (97%) reported a correct action based on PCW use at routine work sites. In Uganda, where data for 127,775 individual patients were available, PCW introduction in health facilities was followed by a decrease in antimalarial prescribing for RDT-negative patients ≥ 5 years of age (4.7-1.9%); among community-based HWs, the decrease was 12.2% (P malaria-endemic areas are able to use prototype PCWs for quality control of malaria RDTs. PCW availability can improve HWs' confidence in RDT results, and benefit malaria diagnostic programs. Lessons learned from this study may be valuable for introduction of other point-of-care diagnostic and quality-control tools. Future work should evaluate longer term impacts of PCWs on patient management. © The American Society of Tropical Medicine and Hygiene.

    Full Text Available Abstract Background Multiple micronutrient deficiencies, in particular iron deficiency anaemia (IDA is a severe public health problem in Lao People's Democratic Republic (Lao PDR. Because of the practical difficulties encountered in improving the nutritional adequacy of traditional complementary foods and the limitations associated with the use of liquid iron supplementation for the treatment and prevention of IDA in infants and young children, recently, home-fortification with multivitamins and minerals sprinkles was recommended. This study aims to compare the effect of twice weekly versus daily supplementation with multivitamins and minerals powder (MMP on anaemia prevalence, haemoglobin concentration, and growth in infants and young children in a rural community in Lao PDR. Methods A randomized trial was conducted in six rural communities. Children aged 6 to 52 months (n = 336 were randomly assigned to a control group (n = 110 or to one of two intervention groups receiving either two sachets per week (n = 115 or a daily sachet (n = 111 of MMP for 24 weeks; 331 children completed the study. A finger prick of blood was taken at baseline, at week 12, and again at week 24 to determine haemoglobin concentration. Anthropometric measurements were taken every 4 weeks. The McNemar test was used to assess within group differences at three time points in the study subjects with anaemia and one-way ANOVA was used to assess changes in mean haemoglobin concentration in the treatment groups. Results MMP supplementation resulted in significant improvements in haemoglobin concentration and in the reduction of anaemia prevalence in the two treatment groups compared with the control group (p Conclusions MMP supplementation had positive effects in reduction of anaemia prevalence and in improving haemoglobin concentration. For severely to moderately anaemic children, daily MMP supplementation was more effective in improving haemoglobin concentration and reducing

    Our understanding of the linkages between the bushmeat trade and the wider informal economy is limited. This lack of knowledge is particularly problematic for conservation under conditions of political instability, when the informal economy can be highly dynamic and impacts on wildlife populations can be severe. To explore these interlinked processes, we conducted a study of the bushmeat trade in Garamba National Park, Democratic Republic of Congo, through a combination of market surveys, semistructured interviews, and direct observation. We focused on the sale of protected and unprotected species in urban and rural markets, and the bushmeat commodity chains that supplied these markets, under conditions of political stability and armed conflict. During peacetime, protected species from the park (predominantly elephant and buffalo) rarely appeared in the rural markets, but they comprised more than half of all bushmeat sales in the urban markets. This pattern reflected differences in the rural and urban commodity chains. Automatic weapons were urban trade. The use of such weapons was discouraged by the traditional chiefs, who administered the village markets. During wartime, the sales of protected species in the urban markets increased fivefold because the military officers fled, leaving behind an open-access system that led to a massive increase in the exploitation of protected species. In contrast, the rural markets remained relatively stable because of the continued authority of the village chiefs. Our results indicate that sociopolitical factors can be an important determinant of species offtake and, therefore, that knowledge of the bushmeat commodity chain can be vital to controlling theprocesses that drive species extraction. In addition, our findings suggest that traditional authorities can be potentially valuable partners for bushmeat management.

    Strongyloidiasis is a major soil-transmitted helminth (STH) disease that affects people worldwide. We present updated data on prevalence in the Lao People's Democratic Republic (Lao PDR) in 2015, arising from a community cross-sectional helminthiasis survey. Fecal samples were collected from 327 individuals across three provinces in Lao PDR (Luang Prabang in the north, Khammouane in the center, and Champasack in the south). Agar plate culture and Kato-Katz methods were used to examine duplicate stool samples from each participant to detect Strongyloides stercoralis and co-infecting helminths. Overall prevalences of S. strercoralis human hookworm, Taenia spp., Trichuris trichiura, Ascaris lumbricoides, and Enterobius vermicularis were 41.0, 28.1, 4.9, 4.0, 1.5, and 0.9 %, respectively. The prevalence of miscellaneous trematodiases (including opisthorchiasis) was 37.9 % and of Schistosoma mekongi infection was 0.3 %. Strongyloidiasis is a current major STH disease in Lao PDR. We also report the molecular-phylogenetic identification of S. stercoralis adult males collected from 40 representative human strongyliodiasis fecal samples. DNA was extracted, amplified, and sequenced from a portion of the mitochondrial cox1 gene and the nuclear 18S ribosomal DNA. Phylogenetic analyses indicated that all specimens sequenced belonged to S. stercoralis (Bavay, 1876) Stiles and Hassall, 1902. The cox1 sequences exhibited great diversity (24 haplotypes) in Lao PDR. This is the first molecular identification and report of genetic diversity of S. stercoralis in humans from Lao PDR. An effective parasite control program is needed to reduce the serious health impacts.

    Full Text Available Little is known about the micronutrient status of women and children in the Democratic Republic of the Congo, which is critical for the design of effective nutrition interventions. We recruited 744 mother-child pairs from South Kivu (SK and Kongo Central (KC. We determined hemoglobin (Hb, serum zinc, vitamin B12, folate, ferritin, soluble transferrin receptor (sTfR, retinol binding protein (RBP, C-reactive protein, and α-1 acid glycoprotein concentrations. Anemia prevalence was determined using Hb adjusted for altitude alone and Hb adjusted for both altitude and ethnicity. Anemia prevalence was lower after Hb adjustment for altitude and ethnicity, compared to only altitude, among women (6% vs. 17% in SK; 10% vs. 32% in KC, children 6–23 months (26% vs. 59% in SK; 25% vs. 42% in KC, and children 24–59 months (14% vs. 35% in SK; 23% vs. 44% in KC, respectively. Iron deficiency was seemingly higher with sTfR as compared to inflammation-adjusted ferritin among women (18% vs. 4% in SK; 21% vs. 5% in KC, children 6–23 months (51% vs. 14% in SK; 74% vs. 10% in KC, and children 24–59 months (23% vs. 4% in SK; 58% vs. 1% in KC. Regardless of indicator, iron deficiency anemia (IDA never exceeded 3% in women. In children, IDA reached almost 20% when sTfR was used but was only 10% with ferritin. Folate, B12, and vitamin A (RBP deficiencies were all very low (<5%; RBP was 10% in children. The prevalence of anemia was unexpectedly low. Inflammation-adjusted zinc deficiency was high among women (52% in SK; 58% in KC, children 6–23 months (23% in SK; 20% in KC, and children 24–59 months (25% in SK; 27% in KC. The rate of biochemical zinc deficiency among Congolese women and children requires attention.

    This paper discusses the occurrence and spatial distribution of metals and persistent organic pollutants (POPs: including organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), Polybrominated diphenyl ethers (PBDEs), and polycyclic aromatic hydrocarbons (PAHs) in sediments from a river-reservoir system. Surface sediments were sampled from thirteen sites of the Congo River Basin and Lake Ma Vallée, both situated in the vicinity of the capital city Kinshasa (Congo Democratic Republic). Sediment qualities were evaluated using toxicity test based on exposing Ostracods to the sediment samples. The highest metal concentrations were observed in sediments subjected to anthropogenic influences, urban runoff and domestic and industrial wastewaters, discharge into the Congo River basin. Ostracods exposed to the sediments resulted in 100% mortality rates after 6d of incubation, indicating the ultimate toxicity of these sediments as well as potential environmental risks. The POPs and PAHs levels in all sediment samples were low, with maximum concentration found in the sediments (area of pool Malebo): OCP value ranged from 0.02 to 2.50 with ∑OCPs: 3.3μgkg(-1); PCB ranged from 0.07 to 0.99 with Total PCBs (∑7×4.3): 15.31μgkg(-1); PAH value ranged from 0.12 to 9.39 with ∑PAHs: 63.89μgkg(-1). Our results indicate that the deterioration of urban river-reservoir water quality result mainly from urban stormwater runoff, untreated industrial effluents which discharge into the river-reservoirs, human activities and uncontrolled urbanization. This study represents useful tools incorporated to evaluate sediment quality in river-reservoir systems which can be applied to similar aquatic environments.

    Rural communities in the Haut-Uele Province of northern Democratic Republic of Congo live in constant danger of attack and/or abduction by units of the Lord's Resistance Army operating in the region. This pilot study sought to develop and evaluate a community-participative psychosocial intervention involving life skills and relaxation training and Mobile Cinema screenings with this war-affected population living under current threat. 159 war-affected children and young people (aged 7-18) from the villages of Kiliwa and Li-May in north-eastern DR Congo took part in this study. In total, 22% of participants had been abduction previously while 73% had a family member abducted. Symptoms of post-traumatic stress reactions, internalising problems, conduct problems and pro-social behaviour were assessed by blinded interviewers at pre- and post-intervention and at 3-month follow-up. Participants were randomised (with an accompanying caregiver) to 8 sessions of a group-based, community-participative, psychosocial intervention (n=79) carried out by supervised local, lay facilitators or a wait-list control group (n=80). Average seminar attendance rates were high: 88% for participants and 84% for caregivers. Drop-out was low: 97% of participants were assessed at post-intervention and 88% at 3 month follow-up. At post-test, participants reported significantly fewer symptoms of post-traumatic stress reactions compared to controls (Cohen's d=0.40). At 3 month follow up, large improvements in internalising symptoms and moderate improvements in pro-social scores were reported, with caregivers noting a moderate to large decline in conduct problems among the young people.

    Shifting cultivation has traditionally been practiced in the Democratic Republic of Congo by carving agricultural fields out of primary and secondary forest, resulting in the rural complex: a characteristic land cover mosaic of roads, villages, active and fallow fields and secondary forest. Forest clearing has varying impacts depending on where it occurs relative to this area: whether inside it, along its primary forest interface, or in more isolated primary forest areas. The spatial contextualization of forest cover loss is therefore necessary to understand its impacts and plan its management. We characterized forest clearing using spatial models in a Geographical Information System, applying morphological image processing to the Forets d’Afrique Central Evaluee par Teledetection product. This process allowed us to create forest fragmentation maps for 2000, 2005 and 2010, classifying previously homogenous primary forest into separate patch, edge, perforated, fragmented and core forest subtypes. Subsequently we used spatial rules to map the established rural complex separately from isolated forest perforations, tracking the growth of these areas in time. Results confirm that the expansion of the rural complex and forest perforations has high variance throughout the country, with consequent differences in local impacts on forest ecology and habitat fragmentation. Between 2000 and 2010 the rural complex grew by 10.2% (46 182 ha), increasing from 11.9% to 13.1% of the total land area (1.2% change) while perforated forest grew by 74.4% (23 856 ha), from 0.8% to 1.5%. Core forest decreased by 3.8% (54 852 ha), from 38% to 36.6% of the 2010 land area. Of particular concern is the nearly doubling of perforated forest, a land dynamic that represents greater spatial intrusion of forest clearing within core forest areas and a move away from the established rural complex.

    Full Text Available BACKGROUND: Outcomes of sexual violence care programmes may vary according to the profile of survivors, type of violence suffered, and local context. Analysis of existing sexual violence care services could lead to their better adaptation to the local contexts. We therefore set out to compare the Médecins Sans Frontières sexual violence programmes in the Democratic Republic of Congo (DRC in a zone of conflict (Masisi, North Kivu and post-conflict (Niangara, Haut-Uélé. METHODS: A retrospective descriptive cohort study, using routine programmatic data from the MSF sexual violence programmes in Masisi and Niangara, DRC, for 2012. RESULTS: In Masisi, 491 survivors of sexual violence presented for care, compared to 180 in Niangara. Niangara saw predominantly sexual violence perpetrated by civilians who were known to the victim (48% and directed against children and adolescents (median age 15 (IQR 13-17, while sexual violence in Masisi was more directed towards adults (median age 26 (IQR 20-35, and was characterised by marked brutality, with higher levels of gang rape, weapon use, and associated violence; perpetrated by the military (51%. Only 60% of the patients in Masisi and 32% of those in Niangara arrived for a consultation within the critical timeframe of 72 hours, when prophylaxis for HIV and sexually transmitted infections is most effective. Survivors were predominantly referred through community programmes. Treatment at first contact was typically efficient, with high (>95% coverage rates of prophylaxes. However, follow-up was poor, with only 49% of all patients in Masisi and 61% in Niangara returning for follow-up, and consequently low rates of treatment and/or vaccination completion. CONCLUSION: This study has identified a number of weak and strong points in the sexual violence programmes of differing contexts, indicating gaps which need to be addressed, and strengths of both programmes that may contribute to future models of context

  8. Fluvial braidplain evolving into lagoonal environment in the coarse marginal facies of the lower buntsandstein relicts in saxony (German Democratic Republic)

    Grunert, Siegfried

    The Lower Buntsandstein in Saxony (German Democratic Republic) is present in mainly isolated relicts in the Zeitz-Schmölln Syncline, the Borna Syncline and the Mügeln Basin where the Nordhausen-Folge and the lower part of the Bernburg-Folge are preserved. The separate occurrences are the remnants of a formerly continuous and extensive distribution of the Buntsandstein which was dissolved and split into pieces by erosion and tectonics. The Buntsandstein overlies the Zechstein; only in the eastern parts of the Mügeln Basin, the Triassic red beds lap on the crystalline basement. Palaeocurrents as revealed from cross-stratification and composition of the gravel-size clasts were directed towards the north and northwest. As most of the pebbles derived from provenance areas that are located some 10 - 30 km south of the occurrences, the Buntsandstein remnants in Saxony represent a marginal part of the basin, as also indicated by the coarse facies. Conglomerates were formed in highly- to moderately-braided river systems operating in braidplain belts or even alluvial-fan chains seaming the basement at the boundary of the depositional area. Towards the centre of the basin, the conglomerate train gives rapidly way to a sand flat in front of the braidplain belt or fan chain where the rivers are no longer capable to transport gravel-size material as a consequence of lowering of the palaeoslope gradient. Accumulation of sand by infilling of shallow watercourses and accretion of mud by plugging of overbank lakes and ponds take place at the margin of a lagoonal sea. The Buntsandstein onlapping on the crystalline basement buries a fossil block package in the granodiorite of the Meißen Massif which originated by weathering and pedogenesis in a semi-arid climate with alternating dry and wet periods. The temporarily brakish lagoonal sea is repeatedly refreshed by influx from braided rivers in the marginal parts that come from the continent.

    Full Text Available Socio-cultural and economic factors constitute real barriers for uptake of screening and treatment of Human African Trypanosomiasis (HAT in the Democratic Republic of Congo (DRC. Better understanding and addressing these barriers may enhance the effectiveness of HAT control.We performed a qualitative study consisting of semi-structured interviews and focus group discussions in the Bandundu and Kasaï Oriental provinces, two provinces lagging behind in the HAT elimination effort. Our study population included current and former HAT patients, as well as healthcare providers and program managers of the national HAT control program. All interviews and discussions were voice recorded on a digital device and data were analysed with the ATLAS.ti software.Health workers and community members quoted a number of prohibitions that have to be respected for six months after HAT treatment: no work, no sexual intercourse, no hot food, not walking in the sun. Violating these restrictions is believed to cause serious, and sometimes deadly, complications. These strong prohibitions are well-known by the community and lead some people to avoid HAT screening campaigns, for fear of having to observe such taboos in case of diagnosis.The restrictions originally aimed to mitigate the severe adverse effects of the melarsoprol regimen, but are not evidence-based and became obsolete with the new safer drugs. Correct health information regarding HAT treatment is essential. Health providers should address the perspective of the community in a constant dialogue to keep abreast of unintended transformations of meaning.

    In Democratic Republic of Congo access to health care is limited because of many geographical and financial barriers, while quality of care is often low. Global health donors assist the country with a number of community-oriented interventions such as free distribution of bednets, antihelminthic drugs, vitamin A supplementation and vaccination campaigns, but uptake of these interventions is not always optimal. The aim of this study was to explore the perceptions of poor urban communities of the capital Kinshasa with regard to health issues in general as well as their experiences and expectations concerning facility-based health services and community-oriented health interventions. Applying an approach rooted in the grounded theory framework, focus group discussions were conducted in eight neighborhoods of poor urban areas in the city of Kinshasa in July 2011. Study participants were easily able to evoke the city's major health problems, with the notable exceptions of malnutrition and HIV/AIDS. They perceive the high out-of-pocket cost of health services as the major obstacle when seeking access to quality care. Knowledge of ongoing community-oriented health interventions seems good. Still, while the study participants agree that those interventions are beneficial; their acceptability seems to be problematic. This is chiefly put down to a lack of information and government communication about the programs and their interventions. Furthermore, the study participants referred to rumors and the deterring effect of stories about alleged harmful consequences of those interventions. Along with improving the provision and quality of general health care, the government and international actors must improve their efforts in informing the communities about disease control programs, their rationale and benefit/risk ratio.

    Four stratified basins in Lake Kivu (Rwanda-Democratic Republic of the Congo) were sampled in March 2007 to investigate the abundance, distribution, and potential biogeochemical role of planktonic archaea. We used fluorescence in situ hybridization with catalyzed-reported deposition microscopic counts (CARD-FISH), denaturing gradient gel electrophoresis (DGGE) fingerprinting, and quantitative PCR (qPCR) of signature genes for ammonia-oxidizing archaea (16S rRNA for marine Crenarchaeota group 1.1a [MCG1] and ammonia monooxygenase subunit A [amoA]). Abundance of archaea ranged from 1 to 4.5% of total DAPI (4',6-diamidino-2-phenylindole) counts with maximal concentrations at the oxic-anoxic transition zone (∼50-m depth). Phylogenetic analysis of the archaeal planktonic community revealed a higher level of richness of crenarchaeal 16S rRNA gene sequences (21 of the 28 operational taxonomic units [OTUs] identified [75%]) over euryarchaeotal ones (7 OTUs). Sequences affiliated with the kingdom Euryarchaeota were mainly recovered from the anoxic water compartment and mostly grouped into methanogenic lineages (Methanosarcinales and Methanocellales). In turn, crenarchaeal phylotypes were recovered throughout the sampled epipelagic waters (0- to 100-m depth), with clear phylogenetic segregation along the transition from oxic to anoxic water masses. Thus, whereas in the anoxic hypolimnion crenarchaeotal OTUs were mainly assigned to the miscellaneous crenarchaeotic group, the OTUs from the oxic-anoxic transition and above belonged to Crenarchaeota groups 1.1a and 1.1b, two lineages containing most of the ammonia-oxidizing representatives known so far. The concomitant vertical distribution of both nitrite and nitrate maxima and the copy numbers of both MCG1 16S rRNA and amoA genes suggest the potential implication of Crenarchaeota in nitrification processes occurring in the epilimnetic waters of the lake.

    A large-scale solar greenhouse dryer with a loading capacity of 1000 kg of fruits or vegetables has been developed and tested at field levels. The dryer has a parabolic shape and the dryer is covered with polycarbonate sheets. The base of the dryer is a black concrete floor with an area of 7.5 x 20.0 m{sup 2}. Nine DC fans powered by three 50-W solar cell modules are used to ventilate the dryer. The dryer was installed at Champasak (15.13 N, 105.79 E) in Lao People's Democratic Republic (Lao PDR). It is routinely used to dry chilli, banana and coffee. To assess the experimental performances of the dryer, air temperature, air relative humidity and product moisture contents were measured. One thousand kilograms of banana with the initial moisture content of 68% (wb) was dried within 5 days, compared to 7 days required for natural sun drying with the same weather conditions. Also three hundred kilograms of chilli with the initial moisture content of 75% (wb) was dried within 3 days while the natural sun drying needed 5 days. Two hundred kilograms of coffee with the initial moisture content of 52% (wb) was dried within 2 days as compared to 4 days required for natural sun drying. The chilli, coffee and banana dried in this dryer were completely protected from insects, animals and rain. Furthermore, good quality of dried products was obtained. The payback period of the dryer is estimated to be 2.5 years. A system of partial differential equations describing heat and moisture transfer during drying of chilli, coffee and banana in the greenhouse dryer was developed. These equations were solved by using the finite different method. The simulated results agree well with the experimental data. This model can be used to provide the design data for this type of dryer in other locations. (author)

    Little is known about the micronutrient status of women and children in the Democratic Republic of the Congo, which is critical for the design of effective nutrition interventions. We recruited 744 mother-child pairs from South Kivu (SK) and Kongo Central (KC). We determined hemoglobin (Hb), serum zinc, vitamin B12, folate, ferritin, soluble transferrin receptor (sTfR), retinol binding protein (RBP), C-reactive protein, and α-1 acid glycoprotein concentrations. Anemia prevalence was determined using Hb adjusted for altitude alone and Hb adjusted for both altitude and ethnicity. Anemia prevalence was lower after Hb adjustment for altitude and ethnicity, compared to only altitude, among women (6% vs. 17% in SK; 10% vs. 32% in KC), children 6-23 months (26% vs. 59% in SK; 25% vs. 42% in KC), and children 24-59 months (14% vs. 35% in SK; 23% vs. 44% in KC), respectively. Iron deficiency was seemingly higher with sTfR as compared to inflammation-adjusted ferritin among women (18% vs. 4% in SK; 21% vs. 5% in KC), children 6-23 months (51% vs. 14% in SK; 74% vs. 10% in KC), and children 24-59 months (23% vs. 4% in SK; 58% vs. 1% in KC). Regardless of indicator, iron deficiency anemia (IDA) never exceeded 3% in women. In children, IDA reached almost 20% when sTfR was used but was only 10% with ferritin. Folate, B12, and vitamin A (RBP) deficiencies were all very low (children. The prevalence of anemia was unexpectedly low. Inflammation-adjusted zinc deficiency was high among women (52% in SK; 58% in KC), children 6-23 months (23% in SK; 20% in KC), and children 24-59 months (25% in SK; 27% in KC). The rate of biochemical zinc deficiency among Congolese women and children requires attention.

    Rapid diagnostic tests (RDTs) are widely used for malaria diagnosis, but lack of quality control at point of care restricts trust in test results. Prototype positive control wells (PCW) containing recombinant malaria antigens have been developed to identify poor-quality RDT lots. This study assessed community and facility health workers' (HW) ability to use PCWs to detect degraded RDTs, the impact of PCW availability on RDT use and prescribing, and preferred strategies for implementation in Lao People's Democratic Republic (Laos) and Uganda. A total of 557 HWs participated in Laos (267) and Uganda (290). After training, most (88% to ≥ 99%) participants correctly performed the six key individual PCW steps; performance was generally maintained during the 6-month study period. Nearly all (97%) reported a correct action based on PCW use at routine work sites. In Uganda, where data for 127,775 individual patients were available, PCW introduction in health facilities was followed by a decrease in antimalarial prescribing for RDT-negative patients ≥ 5 years of age (4.7–1.9%); among community-based HWs, the decrease was 12.2% (P < 0.05) for all patients. Qualitative data revealed PCWs as a way to confirm RDT quality and restore confidence in RDT results. HWs in malaria-endemic areas are able to use prototype PCWs for quality control of malaria RDTs. PCW availability can improve HWs' confidence in RDT results, and benefit malaria diagnostic programs. Lessons learned from this study may be valuable for introduction of other point-of-care diagnostic and quality-control tools. Future work should evaluate longer term impacts of PCWs on patient management. PMID:27895267

    Human conflict generally has substantial negative impacts on wildlife and conservation. The recent civil war (1995-2006) in the Democratic Republic of Congo (DRC) resulted in a significant loss of wildlife, including elephants, due to institutional collapse, lawlessness and unbridled exploitation of natural resources such as minerals, wood, ivory and bushmeat. We used data from distance sampling surveys conducted before and after the war in a protected forest, the Okapi Faunal Reserve, to document changes in elephant abundance and distribution. We employed Generalized Additive Models to relate changes in elephant distribution to human and environmental factors. Populations declined by nearly fifty percent coinciding with a major increase in elephant poaching as indicated by reports of ivory trade during the war. Our results suggest that humans influenced elephant distribution far more than habitat, both before and after the war, but post-war models explained more of the variation. Elephant abundance declined more, closer to the park boundary and to areas of intense human activity. After the war, elephant densities were relatively higher in the centre of the park where they were better protected, suggesting that this area may have acted as a refuge. In other sites in Eastern DRC, where no protection was provided, elephants were even more decimated. Post-war dynamics, such as weakened institutions, human movements and availability of weapons, continue to affect elephants. Survival of remaining populations and recovery will be determined by these persistent factors and by new threats associated with growing human populations and exploitation of natural resources. Prioritizing wildlife protection, curbing illegal trade in ivory and bushmeat, and strengthening national institutions and organizations in charge of conservation will be crucial to counter these threats.

    Full Text Available Two goals have been set for Gambian human African trypanosomiasis (HAT, the first is to achieve elimination as a public health problem in 90% of foci by 2020, and the second is to achieve zero transmission globally by 2030. It remains unclear if certain HAT hotspots could achieve elimination as a public health problem by 2020 and, of greater concern, it appears that current interventions to control HAT in these areas may not be sufficient to achieve zero transmission by 2030. A mathematical model of disease dynamics was used to assess the potential impact of changing the intervention strategy in two high-endemicity health zones of Kwilu province, Democratic Republic of Congo. Six key strategies and twelve variations were considered which covered a range of recruitment strategies for screening and vector control. It was found that effectiveness of HAT screening could be improved by increasing effort to recruit high-risk groups for screening. Furthermore, seven proposed strategies which included vector control were predicted to be sufficient to achieve an incidence of less than 1 reported case per 10,000 people by 2020 in the study region. All vector control strategies simulated reduced transmission enough to meet the 2030 goal, even if vector control was only moderately effective (60% tsetse population reduction. At this level of control the full elimination threshold was expected to be met within six years following the start of the change in strategy and over 6000 additional cases would be averted between 2017 and 2030 compared to current screening alone. It is recommended that a two-pronged strategy including both enhanced active screening and tsetse control is implemented in this region and in other persistent HAT foci to ensure the success of the control programme and meet the 2030 elimination goal for HAT.

    Factual data exploring the relationship between obesity and diabetes mellitus prevalence from rural areas of sub-Saharan Africa remain scattered and are unreliable. To address this scarceness, this work reports population study data describing the relationship between the obesity and the diabetes mellitus in the general population of the rural area of Katana (South Kivu in the Democratic Republic of the Congo). A cohort of three thousand, nine hundred, and sixty-two (3962) adults (>15 years old) were followed between 2012 and 2015 (or 4105 person-years during the observation period), and data were collected using the locally adjusted World Health Organization's (WHO) STEPwise approach to Surveillance (STEPS) methodology. The hazard ratio for progression of obesity was calculated. The association between diabetes mellitus and obesity was analyzed with logistic regression. The diabetes mellitus prevalence was 2.8 % versus 3.5 % for obese participants and 7.2 % for those with metabolic syndrome, respectively. Within the diabetes group, 26.9 % had above-normal waist circumference and only 9.8 % were obese. During the median follow-up period of 2 years, the incidence of obesity was 535/100,000 person-years. During the follow-up, the prevalence of abdominal obesity significantly increased by 23 % (p diabetes mellitus was independently associated with age, waist circumference, and blood pressure but not body mass index. This study confirms an association between diabetes mellitus and abdominal obesity but not with general obesity. On the other hand, the rapid increase in abdominal obesity prevalence in this rural area population within the follow-up period calls for the urgent promoting of preventive lifestyle measures.

    Informal workers often face considerable risks and vulnerabilities as a consequence of their work and employment conditions. The purpose of this study was to examine the interplay between the experience of informal work and access to health, using as an example, female beer promoters employed in the informal economy, in the Lao People's Democratic Republic. In-depth interviews were undertaken with 24 female beer promoters working in beer shops, restaurants and entertainment venues in Vientiane City. The recruitment strategy of snowball sampling was used. Interviews explored the beer promoter's experience of the organization of work, perceived healthcare needs, access to healthcare and insurance, and health seeking practices. The data was analysed thematically and subsequently using Bourdieu's concepts of habitus, capital and field. Most of the beer promoters included in the study were 18 years of age, single, had worked as beer promoters for more than one year and just over half were working to support their higher education. The beer promoters demonstrated a holistic view of health, also viewing good health as contributing to being beautiful - an important attribute in their work. Many reported that their work conditions, including the noisy environment, exposure to second-hand tobacco smoke, long hours on their feet and sexual harassment negatively affected their physical and mental health. Only four participants had any form of health insurance with access to healthcare constrained by individual characteristics, health system factors and the conditions of their informal employment. Drawing on the work of Bourdieu, the study shows how both employment and illness are linked to habitus embodied in everyday practices, access to capital and the position the female beer promoters hold in the social hierarchy in the field of employment.

    Full Text Available Background: Post-partum haemorrhage (PPH is the single largest cause of maternal death worldwide and a particular burden for developing countries. In Africa, about 33.9 % of maternal deaths are due to PPH. In the Democratic Republic of the Congo (DRC, the prevalence of PPH is unknown. PPH can be prevented with active management of the third stage of labour (AMTSL. Objectives: To describe the practice of AMTSL in Vanga Health Zone and to calculate the incidence of PPH in Vanga Health Zone.Method: An intervention study with post-test-only design was conducted among health maternity wards using a data collection sheet to obtain information. All pregnant women attending Vanga Health maternity wards constituted the study population. Frequencies were determined for variables of interest.Results: From April 2007 to March 2008, 6339 deliveries took place at Vanga Health maternity wards, representing 71% of the institutional delivery rate. The number of deliveries realised with the practice of (AMTSL were 5562; 366 cases of PPH were reported, making an incidence of 5.77%. Three cases of maternal deaths – two of which were related to PPH – were reported during the study period, which means there was a decline of 70% compared with the previous two years.Conclusion: The prevalence of PPH has been estimated to be 5.77%; PPH represents the cause of 67% of all maternal deaths. The extension of AMTSL practice, combined with the assurance of better supplies of oxytocin to enhance drug management, is strongly advised/suggested. As a number of births still take place outside the health maternity wards, the introduction of oral misoprostol could be considered a part of AMTSL for use by patients being treated by traditional midwives.

    An open-label, randomized controlled trial was carried out in 2011-2012 in the Democratic Republic of the Congo to test the efficacy, safety, and tolerability of the artemisinin-based combination treatments dihydroartemisinin-piperaquine, amodiaquine-artesunate, and artemether-lumefantrine. Six hundred eighty-four children aged 3 to 59 months with uncomplicated Plasmodium falciparum malaria were randomly allocated to each study arm. Children were hospitalized for 3 days, given supervised treatment, and followed up weekly for 42 days. All regimens were well tolerated and rapidly effective. The median parasitemia clearance half-life was 2.2 h, and half-lives were similar between arms (P=0.19). The PCR-uncorrected cure rates by day 42 were 73.0% for amodiaquine-artesunate, 70.2% for artemether-lumefantrine, and 86.3% for dihydroartemisinin-piperaquine (P=0.001). Early treatment failure occurred in three patients (0.5%), one in each arm. The PCR-corrected cure rates were 93.4% for amodiaquine-artesunate, 92.7% for artemether-lumefantrine, and 94.3% for dihydroartemisinin-piperaquine (P=0.78). The last provided a longer posttreatment prophylactic effect than did the other two treatments. The day 7 plasma concentration of piperaquine was below 30 ng/ml in 47% of the children treated with dihydroartemisinin-piperaquine, and the day 7 lumefantrine concentration was below 280 ng/ml in 37.0% of children who received artemether-lumefantrine. Thus, although cure rates were all satisfactory, they could be improved by increasing the dose.

    Full Text Available BACKGROUND: Buruli ulcer (BU is a necrotizing bacterial infection of skin, subcutaneous tissue and bone caused by Mycobacterium ulcerans. Although the functional impairment caused by BU results in severe suffering and in socio-economic problems, the disease remains largely neglected in Africa. The province of Bas-Congo in Democratic Republic of Congo contains one of the most important BU foci of the country, i.e. the Songololo Territory in the District of Cataractes. This study aims to assess the impact of a BU control project launched in 2004 in the Songololo Territory. METHODS: We used a comparative non-randomized study design, comparing clinical profiles and outcomes of the group of patients admitted at the General Reference Hospital (GRH of the "Institut Médical Evangélique" (IME of Kimpese 3 years before the start of the project (2002-2004 with those admitted during the 3 years after the start of the project (2005-2007. RESULTS: The BU control project was associated with a strong increase in the number of admitted BU cases at the GRH of IME/Kimpese and a fundamental change in the profile of those patients; more female patients presented with BU, the proportion of relapse cases amongst all admissions reduced, the proportion of early lesions and simple ulcerative forms increased, more patients healed without complications and the case fatality rate decreased substantially. The median duration since the onset of first symptoms however remained high, as well as the proportion of patients with osteomyelitis or limitations of joint movement, suggesting that the diagnostic delay remains substantial. CONCLUSION: Implementing a specialized program for BU may be effective in improving clinical profiles and outcomes in BU. Despite these encouraging results, our study highlights the need of considering new strategies to better improve BU control in a low resources setting.

At this level of control the full elimination threshold was expected to be met within six years following the start of the change in strategy and over 6000 additional cases would be averted between 2017 and 2030 compared to current screening alone. It is recommended that a two-pronged strategy including both enhanced active screening and tsetse control is implemented in this region and in other persistent HAT foci to ensure the success of the control programme and meet the 2030 elimination goal for HAT.

    Full Text Available In the Democratic Republic of the Congo (DRC, pigs are raised almost exclusively by smallholders either in periurban areas of major cities such as Kinshasa or in rural villages. Unfortunately, little information is available regarding pig production in the Western part of the DRC, wherefore a survey was carried out to characterize and compare 319 pig production systems in their management and feeding strategies, along a periurban - rural gradient inWestern provinces of the DRC. Pig breeding was the main source of income (43% and half of respondents were active in mixed pig and crop production, mainly vegetable garden. Depending on the location, smallholders owned on average 18 pigs, including four sows. Piglet mortality rate varied from 9.5 to 21.8% while average weaned age ranged between 2.2 and 2.8 months. The major causes of mortality reported by the farmers were African swine fever 98 %, swine erysipelas (60 %, erysipelas trypanosomiasis (31 %, swine worm infection (17 %, and diarrhoea (12 %. The majority of the pigs were reared in pens without free roaming and fed essentially with locally available by-products and forage plants whose nature varied according with the location of the farm. The pig production systems depended on the local environment; particularly in terms of workforces, herd structure and characteristics, production parameters, pig building materials, selling price and in feed resources. It can be concluded that an improvement of Congolese pig production systems should consider (1 a reduction of inbreeding, (2 an improvement in biosafety to reduce the incidence of African swine fever and the spread of other diseases, and (3 an improvement in feeding practices.

    Full Text Available Abstract Background The problem of training human resources in health is a real concern in public health in Central Africa. What can be changed in order to train more competent health professionals? This is of utmost importance in primary health care. Methods Taking into account the level of training of secondary-level nurses in the Democratic Republic of the Congo (DRC, a systemic approach, based on the PRECEDE PROCEED model of analysis, led to a better understanding of the educational determinants and of the factors favourable to a better match between training in health sciences and the expected competences of the health professionals. This article must be read on two complementary levels: one reading, focused on the methodological process, should allow our findings to be transferred to other problems (adaptation of a health promotion model to the educational sphere. The other reading, revolving around the specific theme and results, should provide a frame of reference and specific avenues for action to improve human resources in the health field (using the results of its application in health science teaching in the DRC. Results The results show that it is important to start this training with a global and integrated approach shared by all the actors. The strategies of action entail the need for an approach taking into account all the aspects, i.e. sociological, educational, medical and public health. Conclusions The analysis of the results shows that one cannot bring any change without integrated strategies of action and a multidisciplinary approach that includes all the complex determinants of health behaviour, and to do it within the organization of local structures and institutions in the ministry of health in the DRC.

    Intestinal parasitic infections are common in Lao People's Democratic Republic (Lao PDR). We investigated the accuracy of the Kato-Katz (KK) technique in relation to varying stool sampling efforts, and determined the effect of the concurrent use of a quantitative formalin-ethyl acetate concentration technique (FECT) for helminth diagnosis and appraisal of concomitant infections. The study was carried out between March and May 2006 in Champasack province, southern Lao PDR. Overall, 485 individuals aged ≥6 months who provided three stool samples were included in the final analysis. All stool samples were subjected to the KK technique. Additionally, one stool sample per individual was processed by FECT. Diagnosis was done under a light microscope by experienced laboratory technicians. Analysis of three stool samples with KK plus a single FECT was considered as diagnostic 'gold' standard and resulted in prevalence estimates of hookworm, Opisthorchis viverrini, Ascaris lumbricoides, Trichuris trichiura and Schistosoma mekongi infection of 77.9%, 65.0%, 33.4%, 26.2% and 24.3%, respectively. As expected, a single KK and a single FECT missed a considerable number of infections. While our diagnostic 'gold' standard produced similar results than those obtained by a mathematical model for most helminth infections, the 'true' prevalence predicted by the model for S. mekongi (28.1%) was somewhat higher than after multiple KK plus a single FECT (24.3%). In the current setting, triplicate KK plus a single FECT diagnosed helminth infections with high sensitivity. Hence, such a diagnostic approach might be utilised for generating high-quality baseline data, assessing anthelminthic drug efficacy and rigorous monitoring of community interventions.

    In zones of violent conflict in the tropics, social disruption leads to elevated child mortality, of which malaria is the leading cause. Understanding the social determinants of malaria transmission may be helpful to optimize malaria control efforts. We conducted a cross-sectional study of healthy children aged 2 months to 5 years attending well-child and/or immunization visits in the Democratic Republic of Congo (DRC). Six hundred and forty-seven children were tested for malaria antigenemia by rapid diagnostic test and the accompanying parent or legal guardian simultaneously completed a survey questionnaire related to demographics, socioeconomic status, maternal education, as well as bednet use and recent febrile illness. We examined the associations between variables using multivariable logistic regression analysis, chi-squared statistic, Fisher's exact test, and Spearman's rank correlation, as appropriate. One hundred and twenty-three out of the 647 (19%) children in the study tested positive for malaria. Higher levels of maternal education were associated with a lower risk of malaria in their children. The prevalence of malaria in children of mothers with no education, primary school, and beyond primary was 41/138 (30%), 41/241 (17%), and 39/262 (15%), respectively (p = 0.001). In a multivariable logistic regression model adjusting for the effect of a child's age and study site, the following remained significant predictors of malaria antigenemia: maternal education, number of children under five per household, and HIV serostatus. Higher maternal education, through several putative causal pathways, was associated with lower malaria prevalence among children in the DRC. Our findings suggest that maternal education might be an effective 'social vaccine' against malaria in the DRC and globally.

    Objective:To compare perceived ill-health and health seeking behavior between two communities affected by the large Nam Theun 2 hydroelectric project in central Lao People's Democratic Republic (PDR).Methods:Two different affected areas:Nakai plateaubeing remote,sparcely populated and mountainous,and Xe Bang Fai lowland plains,more densely populated and comparatively affluent were included.Data were obtained from two cross-sectional household-based health and socio-economic surveys.Results:We found pronounced differ-ences in the frequency of self-reported fever,cough,headache and myalgia according to location.On the Na-kai plateau,45.1 % of the individuals with ill-health report (recall period:2 weeks)went to a local health volunteer compared to only 7.2 % in the Xe Bang Fai area (P <0.001).In Nakai,there were disproportion-ately more illiterates seeking help from local health volunteers when compared to those who attended at least primary schooling (49.2 % versus 17.5 %,P <0.01).Self-medication with antimalarials was more common in Xe Bang Fai than on Nakai (32.3 % versus 7.0 %,P <0.001).The mean amount of money spent per health consultation was US $1.7 in Nakai and US $7.2 in Xe Bang Fai.Conclusion:The observed differ-ences in self-reported ill-health and health seeking behavior among these two Lao communities need to be con-sidered when implementing setting-specific mitigation measures as part of the public health action plan of the Nam Theun 2 hydroelectric project.

  9. Resource wars and conflict ivory: the impact of civil conflict on elephants in the Democratic Republic of Congo--the case of the Okapi Reserve.

    Rene L Beyers

    Full Text Available Human conflict generally has substantial negative impacts on wildlife and conservation. The recent civil war (1995-2006 in the Democratic Republic of Congo (DRC resulted in a significant loss of wildlife, including elephants, due to institutional collapse, lawlessness and unbridled exploitation of natural resources such as minerals, wood, ivory and bushmeat. We used data from distance sampling surveys conducted before and after the war in a protected forest, the Okapi Faunal Reserve, to document changes in elephant abundance and distribution. We employed Generalized Additive Models to relate changes in elephant distribution to human and environmental factors. Populations declined by nearly fifty percent coinciding with a major increase in elephant poaching as indicated by reports of ivory trade during the war. Our results suggest that humans influenced elephant distribution far more than habitat, both before and after the war, but post-war models explained more of the variation. Elephant abundance declined more, closer to the park boundary and to areas of intense human activity. After the war, elephant densities were relatively higher in the centre of the park where they were better protected, suggesting that this area may have acted as a refuge. In other sites in Eastern DRC, where no protection was provided, elephants were even more decimated. Post-war dynamics, such as weakened institutions, human movements and availability of weapons, continue to affect elephants. Survival of remaining populations and recovery will be determined by these persistent factors and by new threats associated with growing human populations and exploitation of natural resources. Prioritizing wildlife protection, curbing illegal trade in ivory and bushmeat, and strengthening national institutions and organizations in charge of conservation will be crucial to counter these threats.

  10. Multiparty Compatibility for Concurrent Objects

    Full Text Available Objects and actors are communicating state machines, offering and consuming different services at different points in their lifecycle. Two complementary challenges arise when programming such systems. When objects interact, their state machines must be "compatible", so that services are requested only when they are available. Dually, when objects refine other objects, their state machines must be "compliant", so that services are honoured whenever they are promised. In this paper we show how the idea of multiparty compatibility from the session types literature can be applied to both of these problems. We present an untyped language in which concurrent objects are checked automatically for compatibility and compliance. For simple objects, checking can be exhaustive and has the feel of a type system. More complex objects can be partially validated via test cases, leading to a methodology closer to continuous testing. Our proof-of-concept implementation is limited in some important respects, but demonstrates the potential value of the approach and the relationship to existing software development practices.

    2016-09-01

    Full Text Available Although it is common for armed groups to splinter (or “fragment” during contexts of multi-party civil war, current guidance on Disarmament, Demobilization, and Reintegration (DDR does not address the challenges that arise when recalcitrant fighters, unwilling to report to DDR, break ranks and form new armed groups. This Practice Note addresses this issue, drawing lessons from the multi-party context of the DRC and from the experiences of former members of three armed groups: the Rally for Congolese Democracy-Goma (RCD-Goma, the National Congress for the Defense of the People (CNDP, and the DRC national army (FARDC. While the findings indicate that the fragmentation of armed groups may encourage desertion and subsequent participation in DDR, they also show that active armed groups may monitor DDR programs and track those who demobilize. Remobilization may follow, either as active armed groups target ex-combatants for forced re-recruitment or as ex-combatants remobilize in armed groups of their own choice. Given these dynamics, practitioners in settings of partial peace may find it useful to consider non-traditional methods of DDR such as the use of mobile patrols and mobile disarmament units. The temporary relocation of ex-combatants to safe areas free from armed groups, or to protected transitional assistance camps, may also help to minimize remobilization during the reintegration phase.

    Full Text Available BACKGROUND: Household water treatment can improve the microbiological quality of drinking water and may prevent diarrheal diseases. However, current methods of treating water at home have certain shortcomings, and there is evidence of bias in the reported health impact of the intervention in open trial designs. METHODS AND FINDINGS: We undertook a randomised, double-blinded, placebo-controlled trial among 240 households (1,144 persons in rural Democratic Republic of Congo to assess the field performance, use and effectiveness of a novel filtration device in preventing diarrhea. Households were followed up monthly for 12 months. Filters and placebos were monitored for longevity and for microbiological performance by comparing thermotolerant coliform (TTC levels in influent and effluent water samples. Mean longitudinal prevalence of diarrhea was estimated among participants of all ages. Compliance was assessed through self-reported use and presence of water in the top vessel of the device at the time of visit. Over the 12-month follow-up period, data were collected for 11,236 person-weeks of observation (81.8% total possible. After adjusting for clustering within the household, the longitudinal prevalence ratio of diarrhoea was 0.85 (95% confidence interval: 0.61-1.20. The filters achieved a 2.98 log reduction in TTC levels while, for reasons that are unclear, the placebos achieved a 1.05 log reduction (p<0.0001. After 8 months, 68% of intervention households met the study's definition of current users, though most (73% of adults and 95% of children also reported drinking untreated water the previous day. The filter maintained a constant flow rate over time, though 12.4% of filters were damaged during the course of the study. CONCLUSIONS: While the filter was effective in improving water quality, our results provide little evidence that it was protective against diarrhea. The moderate reduction observed nevertheless supports the need for larger

    Although questions of modern human origins and dispersal are subject to intense research within and outside Africa, the processes of modern human diversification during the Late Pleistocene are most often discussed within the context of recent human genetic data. This situation is due largely to the dearth of human fossil remains dating to the final Pleistocene in Africa and their almost total absence from West and Central Africa, thus limiting our perception of modern human diversification within Africa before the Holocene. Here, we present a morphometric comparative analysis of the earliest Late Pleistocene modern human remains from the Central African site of Ishango in the Democratic Republic of Congo. The early Late Stone Age layer (eLSA) of this site, dated to the Last Glacial Maximum (25-20 Ky), contains more than one hundred fragmentary human remains. The exceptional associated archaeological context suggests these remains derived from a community of hunter-fisher-gatherers exhibiting complex social and cognitive behaviors including substantial reliance on aquatic resources, development of fishing technology, possible mathematical notations and repetitive use of space, likely on a seasonal basis. Comparisons with large samples of Late Pleistocene and early Holocene modern human fossils from Africa and Eurasia show that the Ishango human remains exhibit distinctive characteristics and a higher phenotypic diversity in contrast to recent African populations. In many aspects, as is true for the inner ear conformation, these eLSA human remains have more affinities with Middle to early Late Pleistocene fossils worldwide than with extant local African populations. In addition, cross-sectional geometric properties of the long bones are consistent with archaeological evidence suggesting reduced terrestrial mobility resulting from greater investment in and use of aquatic resources. Our results on the Ishango human remains provide insights into past African modern

    Full Text Available Sleeping sickness caused by Trypanosoma brucei (T.b. gambiense constitutes a serious health problem in sub-Sahara Africa. In some foci, alarmingly high relapse rates were observed in patients treated with melarsoprol, which used to be the first line treatment for patients in the neurological disease stage. Particularly problematic was the situation in Mbuji-Mayi, East Kasai Province in the Democratic Republic of the Congo with a 57% relapse rate compared to a 5% relapse rate in Masi-Manimba, Bandundu Province. The present study aimed at investigating the mechanisms underlying the high relapse rate in Mbuji-Mayi using an extended collection of recently isolated T.b. gambiense strains from Mbuji-Mayi and from Masi-Manimba.Forty five T.b. gambiense strains were used. Forty one were isolated from patients that were cured or relapsed after melarsoprol treatment in Mbuji-Mayi. In vivo drug sensitivity tests provide evidence of reduced melarsoprol sensitivity in these strains. This reduced melarsoprol sensitivity was not attributable to mutations in TbAT1. However, in all these strains, irrespective of the patient treatment outcome, the two aquaglyceroporin (AQP 2 and 3 genes are replaced by chimeric AQP2/3 genes that may be associated with resistance to pentamidine and melarsoprol. The 4 T.b. gambiense strains isolated in Masi-Manimba contain both wild-type AQP2 and a different chimeric AQP2/3. These findings suggest that the reduced in vivo melarsoprol sensitivity of the Mbuji-Mayi strains and the high relapse rates in that sleeping sickness focus are caused by mutations in the AQP2/AQP3 locus and not by mutations in TbAT1.We conclude that mutations in the TbAQP2/3 locus of the local T.b. gambiense strains may explain the high melarsoprol relapse rates in the Mbuji-Mayi focus but other factors must also be involved in the treatment outcome of individual patients.

    Full Text Available Rare systemic studies concerning prevalence of intestinal parasites in children have been conducted in the second smallest country in Africa, the Democratic Republic of São Tomé and Príncipe. Fecal specimens from 348 children (214 in-hospital attending the Aires de Menezes Hospital and 134 from Agostinho Neto village in São Tome Island were studied by parasitological and molecular methods. Of the 134 children from Agostinho Neto, 52.2% presented intestinal parasites. 32.1% and 20.2% of these children had monoparasitism and polyparasitism, respectively. Ascaris lumbricoides (27.6%, G. duodenalis (7.5%, T. trichiura (4.5% and Entamoeba coli (10.5% were the more frequent species identified in the children of this village. Giardia duodenalis (7.5% and E. bieneusi (5.2% were identified by PCR. Nested-PCR targeting G. duodenalis TPI identified Assemblage A (60% and Assemblage B (40%. The E. bieneusi ITS-based sequence identified genotypes K (57.1%, KIN1 (28.6% and KIN3 (14.3%. Among the 214 in-hospital children, 29.4% presented intestinal parasites. In 22.4% and 7.0% of the parasitized children, respectively, one or more species were concurrently detected. By microscopy, A. lumbricoides (10.3% and Trichiuris trichiura (6.5% were the most prevalent species among these children, and Cryptosporidium was detected by PCR in 8.9% of children. GP60 locus analysis identified 6.5% of C. hominis (subtypes IaA27R3 [35.7%], IaA23R3 [14.3%], IeA11G3T3 [28.6%] and IeA11G3T3R1 [21.4%] and 2.3% of C. parvum (subtypes IIaA16G2R1 [20.0%], IIaA15G2R1 [20.0%], IIdA26G1 [40.0%] and IIdA21G1a [20.0%].

    Dietfried Müller-Hegemann was one of the prominent figures in East German psychiatry and psychotherapy of the 1950s and 1960s. Having been a communist prior to 1933, a resistance fighter during the National Socialist regime and having gone through political training during his exile in Soviet Russia, he proved to be a committed member of the new ruling SED socialist party in Eastern Germany. As such both governmental and party organs regarded him as a promising and reliable party member to be supported and implemented as executive staff within the new, socialist scientific system. Also, due to the fact that he supported the Pavlovian school of thought for modern psychiatry, Müller-Hegemann was installed as the new head of the Department of Neurology and Psychiatry at Leipzig University by the state secretary for higher education, notably against the clear opposition of the university medical faculty. Soon thereafter however Müller-Hegemann fell from favor due to the fact that he supported views that did not follow the strict ideological guidelines, e. g. with regard to the emergence of fascism. Moreover, he strongly opposed the separation of neurology from psychiatry as ruled by the ministry. An attempt in 1963 by junior party members and ministerial staff to remove him from office failed, but still managed to make Müller-Hegemann resign from his Leipzig post and take over that of director of the Griesinger hospital for the mentally ill in East Berlin. In May 1971, after new conflicts with party officials, he did not return from a business trip to Essen in West Germany. This study does not review the scientific and medical merits of Müller-Hegemann, but concentrates on how his career as a leading psychiatrist was manipulated, both supported and sabotaged, and ideologically controlled by the German Democratic Republic (GDR) system. His development is documented proof that party officials did not tolerate opposition, neither in ideological nor in

Girls were associated with S. mansoni infection (p = 0.04). T. trichiura was the most prevalent STH infection (26.3%), followed by A. lumbricoides (20.1%). Co-infection with malaria-S. mansoni and malaria-STH was, respectively, 1.5% (CI95%:0.7–3.3) and 6.4% (CI95% 4.4–9.1). The prevalence of anemia was found to be 41.6% (95%CI:37.7–45.6) and anemia was strongly related with Plasmodium ssp infection (aOR:4.1; CI95%:2.6–6.5;panemia in schoolchildren. Therefore, specific school-based interventions, such as intermittent preventive treatment or prophylaxis, LLITN distribution, anthelminthic mass treatment and micronutrient supplementation are needed

    Long-lasting insecticidal nets (LLIN) are a highly effective means for preventing malaria infection and reducing associated morbidity and mortality. Mass free distribution campaigns have been shown to rapidly increase LLIN ownership and use. Around 3.5 million LLINs were distributed free of charge in the Kasaï Occidental Province in the Democratic Republic of Congo (DRC) in September-October 2014, using two different approaches, a fixed delivery strategy and a door-to-door strategy including hang-up activities. Repeated community-based cross-sectional surveys were conducted 2 months before and six months after the mass distribution. Descriptive statistics were used to measure changes in key malaria household indicators. LLIN ownership and use were compared between delivery strategies. Univariate and multivariate logistic regression analyses were used to identify factors associated with LLIN use before and after the mass distribution. A comparative financial cost analysis between the fixed delivery and door-to-door distribution strategies was carried out from the provider's perspective. Household ownership of at least one LLIN increased from 39.4% pre-campaign to 91.4% post-campaign and LLIN universal coverage, measured as the proportion of households with at least one LLIN for every two people increased from 4.1 to 41.1%. Population access to LLIN within the household increased from 22.2 to 80.7%, while overall LLIN use increased from 18.0 to 68.3%. Higher LLIN ownership was achieved with the fixed delivery strategy compared with the door-to-door (92.5% [95% CI 90.2-94.4%] versus 85.2% [95% CI 78.5-90.0%]), while distribution strategy did not have a significant impact on LLIN use (69.6% [95% CI 63.1-75.5%] versus 65.7% [95% CI 52.7-76.7%]). Malaria prevalence among children aged 6-59 months was 44.8% post-campaign. Living in a household with sufficient numbers of LLIN to cover all members was the strongest determinant of LLIN use. The total financial cost per

    Cash transfer programs (CTPs) aim to strengthen financial security for vulnerable households. This potentially enables improvements in diet, hygiene, health service access and investment in food production or income generation. The effect of CTPs on the outcome of children already severely malnourished is not well delineated. The objective of this study was to test whether CTPs will improve the outcome of children treated for severe acute malnutrition (SAM) in the Democratic Republic of the Congo over 6 months. We conducted a cluster-randomised controlled trial in children with uncomplicated SAM who received treatment according to the national protocol and counselling with or without a cash supplement of US$40 monthly for 6 months. Analyses were by intention to treat. The hazard ratio of reaching full recovery from SAM was 35% higher in the intervention group than the control group (adjusted hazard ratio, 1.35, 95% confidence interval (CI) = 1.10 to 1.69, P = 0.007). The adjusted hazard ratios in the intervention group for relapse to moderate acute malnutrition (MAM) and SAM were 0.21 (95% CI = 0.11 to 0.41, P = 0.001) and 0.30 (95% CI = 0.16 to 0.58, P = 0.001) respectively. Non-response and defaulting were lower when the households received cash. All the nutritional outcomes in the intervention group were significantly better than those in the control group. After 6 months, 80% of cash-intervened children had re-gained their mid-upper arm circumference measurements and weight-for-height/length Z-scores and showed evidence of catch-up. Less than 40% of the control group had a fully successful outcome, with many deteriorating after discharge. There was a significant increase in diet diversity and food consumption scores for both groups from baseline; the increase was significantly greater in the intervention group than the control group. CTPs can increase recovery from SAM and decrease default, non-response and relapse rates during and

    Full Text Available Abstract Background The Malanga sleeping sickness focus of the Democratic Republic of Congo has shown an epidemic evolution of disease during the last century. However, following case detection and treatment, the prevalence of the disease decreased considerably. No active survey has been undertaken in this focus for a couple of years. To understand the current epidemiological status of sleeping sickness as well as the animal African trypanosomiasis in the Malanga focus, we undertook the identification of tsetse blood meals as well as different trypanosome species in flies trapped in this focus. Methods Pyramidal traps were use to trap tsetse flies. All flies caught were identified and live flies were dissected and their mid-guts collected. Fly mid-gut was used for the molecular identification of the blood meal source, as well as for the presence of different trypanosome species. Results About 949 Glossina palpalis palpalis were trapped; 296 (31.2% of which were dissected, 60 (20.3% blood meals collected and 57 (19.3% trypanosome infections identified. The infection rates were 13.4%, 5.1%, 3.5% and 0.4% for Trypanosoma congolense savannah type, Trypanosoma brucei s.l., Trypanosoma congolense forest type and Trypanosoma vivax, respectively. Three mixed infections including Trypanosoma brucei s.l. and Trypanosoma congolense savannah type, and one mixed infection of Trypanosoma vivax and Trypanosoma congolense savannah type were identified. Eleven Trypanosoma brucei gambiense infections were identified; indicating an active circulation of this trypanosome subspecies. Of all the identified blood meals, about 58.3% were identified as being taken on pigs, while 33.3% and 8.3% were from man and other mammals, respectively. Conclusion The presence of Trypanosoma brucei in tsetse mid-guts associated with human blood meals is indicative of an active transmission of this parasite between tsetse and man. The considerable number of pig blood meals combined

  11. Remote Operation on Quantum State Among Multiparty

    2007-01-01

    In this paper, a scheme is proposed for performing remote operation on quantum state among multiparty.We use three-particle GHZ state as quantum channels to prepare a state operator, which describes quantum correlation between states and operations. Based on the special characteristic of the state operator, observers can perform unitary operation on a system that is away from observers. Our studies show this process is deterministic. We further consider remote operation among N spatially distributed observers, and the results show the successful realization of remote operation needs collective participation of N parties, that is, there exists strong correlation among multiparty. In addition, we investigate the case in which observers share a three-particle W state as quantum channels to perform remote operation and studies find this process is probabilistic.

    Introduction In the field of tuberculosis (TB), and particularly in regard to paediatric TB (PedTB), clinical skills of health professionals play an important role in determining quality of care. In an era where novel diagnostic technologies and efficient treatment regimens are being made available for the poorest, we must not divert our attention from the importance of clinical skills, as this deliverable remains the cornerstone of individualized patient care and ultimately the best assurance for optimal use of resources. The aim of our work was to study the epidemiology of PedTB and the determinants of PedTB under-detection in the South-Kivu Province of the Democratic Republic of Congo (DRC), a setting with nearly no technical resources allowing to support the clinical diagnosis of PedTB, i.e. chest X-rays, rapid molecular tests or culture laboratories. Methods We collected TB notification data from 2010 to 2015 and analysed the space-time variations in notification for the different forms of TB among the 113 health facilities (HF) the South-Kivu Province, a region with a low HIV incidence. The different forms of TB notified were: smear positive pulmonary TB (SS+PTB), smear negative pulmonary TB (SS-PTB) and extra-pulmonary TB (EPTB). We further analysed the distribution of these different forms of the disease per age group and explored the possibility to predict the detection of PedTB. Results Significant differences were observed between HF in regard to the proportion of paediatric TB and the proportion of SS-TB among adults. We found a strong correlation between the proportion of PedTB and three major factors: the proportion of TB cases with no bacteriological confirmation (SS-TB) among adults, the number of TB cases notified by the HF and the fact that the HF was supported or not by Médecins Sans Frontières (MSF). The proportion of SS-TB among adults was found to be a valid indicator for predicting the level of detection of PedTB at the same HF. Conclusion

    Full Text Available The scaling up of antiviral treatment (ART coverage in the past decade has increased access to care for numerous people living with HIV/AIDS (PLWHA in low-resource settings. Out-of-pocket payments (OOPs represent a barrier for healthcare access, adherence and ART effectiveness, and can be economically catastrophic for PLWHA and their family. We evaluated OOPs of PLWHA attending outpatient and inpatient care units and estimated the financial burden for their households in the Lao People's Democratic Republic.

    Full Text Available Abstract Background The use of maternal health services, known as an indirect indicator of perinatal death, is still unknown in Lubumbashi. The present study was therefore undertaken in order to determine the factors that influence the use of mother and child healthcare services in Lubumbashi, Democratic Republic of the Congo. Methods This was transversal study of women residing in Lubumbashi who had delivered between January and December 2009. In total, 1762 women were sampled from households using indicator cluster surveys in all health zones. Antenatal consultations (ANC, delivery assisted by qualified healthcare personnel (and delivery in a healthcare facility as well as postnatal consultations (PNC were dependent variables of study. The factors determining non-use of maternal healthcare services were researched via logistic regression with a 5% materiality threshold. Results The use of maternal healthcare services was variable; 92.6% of women had attended ANC at least once, 93.8% of women had delivered at a healthcare facility, 97.2% had delivered in the presence of qualified healthcare personnel, while the rate of caesarean section was 4.5%. Only 34.6% postnatal women had attended PNC by 42 days after delivery. During these ANC visits, only 60.6% received at least one dose of vaccine, while 38.1% received Mebendazole, 35.6% iron, 32.7% at least one dose of SulfadoxinePyrimethamine, 29.2% folic acid, 15.5% screening for HIV and 12.8% an insecticide treated net. In comparison to women that had had two or three deliveries before, primiparous and grand multiparous women were twice as likely not to use ANC during their pregnancy. Women who had unplanned pregnancies were also more likely not to use ANC or PNC than those who had planned pregnancies alone or with their partner. The women who had not used ANC were also more likely not to use PNC. The women who had had a trouble-free delivery were more likely not to use PNC than those who had

  17. An Erlang Implementation of Multiparty Session Actors

    2016-08-01

    Full Text Available By requiring co-ordination to take place using explicit message passing instead of relying on shared memory, actor-based programming languages have been shown to be effective tools for building reliable and fault-tolerant distributed systems. Although naturally communication-centric, communication patterns in actor-based applications remain informally specified, meaning that errors in communication are detected late, if at all. Multiparty session types are a formalism to describe, at a global level, the interactions between multiple communicating entities. This article describes the implementation of a prototype framework for monitoring Erlang/OTP gen_server applications against multiparty session types, showing how previous work on multiparty session actors can be adapted to a purely actor-based language, and how monitor violations and termination of session participants can be reported in line with the Erlang mantra of "let it fail". Finally, the framework is used to implement two case studies: an adaptation of a freely-available DNS server, and a chat server.

    The Central African Copperbelt (CACB) is one of the most important copper-producing regions of the world. The majority of copper produced in Africa comes from this region defined by the Neoproterozoic Katanga sedimentary basin of the southern Democratic Republic of the Congo (DRC) and northern Zambia. Copper in the CACB is mined from sediment-hosted stratabound copper deposits associated with red beds and includes the giant deposits in the Kolwezi and Tenge-Fungurume districts in the DRC and the Konkola-Musoshi and Nchanga-Chingola districts in Zambia. In recent years, sediment-hosted structurally controlled replacement and vein (SCRV) copper deposits, such as the giant Kansanshi deposit in Zambia have become important exploration targets in the CACB region.

    In this study, we characterized HIV-1 strains from the Democratic Republic of Congo (DRC), previously described as divergent subtype A (n = 1, 97CD.KMST91) or untypable (n = 7) in the V3-V5 env region. Four strains had the same structure over the entire genome, including alternating fragments of a new subsubtype, A5, within the subtype A radiation and fragments that remain unclassified. Therefore, the cluster of new viruses represents a new circulating recombinant, CRF26_A5U. Three additional strains were unique recombinants with the newly described CRF26_A5U and subtype C. Finally, the nearly full-length sequence of 97CD.KMST91 showed that this strain also consisted of alternating fragments of a divergent subtype A lineage and unclassified fragments, although different from previously reported A and U sequences. The high genetic distances among the different CRF26-A5U strains suggest their longstanding presence in the DRC.

    Franson-like setups are inadequate for multiparty Bell experiments with energy-time entanglement because postselected events can depend on the local settings, and local models can exploit this feature to reproduce the quantum predictions, even in the case of ideal devices. We extend a previously introduced interferometric scheme [A. Cabello , Phys. Rev. Lett. 102, 040401 (2009)] to solve this problem in the N-qubit and N-quNit cases. In addition, the proposed setups allow us to prepare and test N-qubit Greenberger-Horne-Zeilinger and (∑i=1N|i…i>)/N energy-time entangled states.

    Full Text Available With the advent of the information age, the network security is particularly important. The secure multiparty computation is a very important branch of cryptography. It is a hotspot in the field of information security. It expanded the scope of the traditional distributed computing and information security, provided a new computing model for the network collaborative computing. First we introduced several key technologies of secure multiparty computation: secret sharing and verifiable secret sharing, homomorphic public key cryptosystem, mix network, zero knowledge proof, oblivious transfer, millionaire protocol. Second we discussed the applications of secure multiparty computation in electronic voting, electronic auctions, threshold signature, database queries, data mining, mechanical engineering and other fields.

    Full Text Available The Democratic Republic of Congo (DRC is the country in the world which reported the highest number of cholera cases to WHO from 2002 to 2007 (128 936 cases out of a worldwide 902 071 cases. We, therefore, implemented research work which intends to understand the epidemiology of cholera in the DRC and to ensure improvements in the strategy to fight against cholera. This broad study enabled us to accurately determine the cholera epidemic’s mechanisms on different scales; to identify the source zones of the disease, and the groups of populations acting as vectors of the spread. It was then possible to demonstrate the role of “sanctuary”, played by some suburbs of lakeside cities. A collaborative network, including several scientific institutions in Europe and in the DRC, local and national government administrations in the field of public health and sanitation, international agencies, NGOs and private foundations, was progressively set up. Following the conclusions of our epidemiological studies, a drastic change of strategy was proposed: the limited curative approach on the one hand, the few existing water/sanitation programs on the other hand, have been merged in a global approach involving a larger scale water and sanitation infrastructure improvement, environmental protection, hygiene awareness and medical surveys targeting a few focus areas playing a central role in the epidemics. In conclusion, by better targeting intervention zones, one can gather human and technical resources previously scattered on the vast territory of the DRC. The strategy presented here revives the hope to eliminate cholera in the DRC.La République Démocratique du Congo (RDC est le pays qui a déclaré le plus grand nombre de cas de choléra à l’OMS entre 2002 et 2007 (128 936 cas sur un nombre total de 902 071 de cas dans le monde.

    Assess mental health outcomes among women raising children from sexual violence-related pregnancies (SVRPs) in eastern Democratic Republic of Congo and stigma toward and acceptance of women and their children. Participants were recruited using respondent-driven sampling. Bukavu, Democratic Republic of Congo in 2012. 757 adult women raising children from SVRPs were interviewed. A woman aged 18 and older was eligible for the study if she self-identified as a sexual violence survivor since the start of the conflict (∼1996), conceived an SVRP, delivered a liveborn child and was currently raising the child. A woman was ineligible for the study if the SVRP ended with a spontaneous abortion or fetal demise or the child was not currently living or in the care of the biological mother. Trained female Congolese interviewers verbally administered a quantitative survey after obtaining verbal informed consent. Symptom criteria for major depressive disorder, post-traumatic stress disorder, anxiety and suicidality were assessed, as well as stigma toward the woman and her child. Acceptance of the woman and child from the spouse, family and community were analysed. 48.6% met symptom criteria for major depressive disorder, 57.9% for post-traumatic stress disorder, 43.3% for anxiety and 34.2% reported suicidality. Women who reported stigma from the community (38.4%) or who reported stigma toward the child from the spouse (42.9%), family (31.8%) or community (38.1%) were significantly more likely to meet symptom criteria for most mental health disorders. Although not statistically significant, participants who reported acceptance and acceptance of their children from the spouse, family and community were less likely to meet symptom criteria. Women raising children from SVRPs experience symptoms of mental health disorders. Programming addressing stigma and acceptance following sexual violence may improve mental health outcomes in this population. Published by the BMJ Publishing Group

  9. Buffered Communication Analysis in Distributed Multiparty Sessions

    Deniélou, Pierre-Malo; Yoshida, Nobuko

    Many communication-centred systems today rely on asynchronous messaging among distributed peers to make efficient use of parallel execution and resource access. With such asynchrony, the communication buffers can happen to grow inconsiderately over time. This paper proposes a static verification methodology based on multiparty session types which can efficiently compute the upper bounds on buffer sizes. Our analysis relies on a uniform causality audit of the entire collaboration pattern - an examination that is not always possible from each end-point type. We extend this method to design algorithms that allocate communication channels in order to optimise the memory requirements of session executions. From these analyses, we propose two refinements methods which respect buffer bounds: a global protocol refinement that automatically inserts confirmation messages to guarantee stipulated buffer sizes and a local protocol refinement to optimise asynchronous messaging without buffer overflow. Finally our work is applied to overcome a buffer overflow problem of the multi-buffering algorithm.

  10. Precise subtyping for synchronous multiparty sessions

    Full Text Available The notion of subtyping has gained an important role both in theoretical and applicative domains: in lambda and concurrent calculi as well as in programming languages. The soundness and the completeness, together referred to as the preciseness of subtyping, can be considered from two different points of view: operational and denotational. The former preciseness has been recently developed with respect to type safety, i.e. the safe replacement of a term of a smaller type when a term of a bigger type is expected. The latter preciseness is based on the denotation of a type which is a mathematical object that describes the meaning of the type in accordance with the denotations of other expressions from the language. The result of this paper is the operational and denotational preciseness of the subtyping for a synchronous multiparty session calculus. The novelty of this paper is the introduction of characteristic global types to prove the operational completeness.

    We introduce a new approach to multiparty computation (MPC) basing it on homomorphic threshold crypto-systems. We show that given keys for any sufficiently efficient system of this type, general MPC protocols for n parties can be devised which are secure against an active adversary that corrupts...... any minority of the parties. The total number of bits broadcast is O(nk|C|), where k is the security parameter and |C| is the size of a (Boolean) circuit computing the function to be securely evaluated. An earlier proposal by Franklin and Haber with the same complexity was only secure for passive...... adversaries, while all earlier protocols with active security had complexity at least quadratic in n. We give two examples of threshold cryptosystems that can support our construction and lead to the claimed complexities....

    2003-01-01

    Quantum entanglement, perhaps the most non-classical manifestation of quantum information theory, cannot be used to transmit information between remote parties. Yet, it can be used to reduce the amount of communication required to process a variety of distributed computational tasks. We speak of pseudo-telepathy when quantum entanglement serves to eliminate the classical need to communicate. In earlier examples of pseudo-telepathy, classical protocols could succeed with high probability unless the inputs were very large. Here we present a simple multi-party distributed problem for which the inputs and outputs consist of a single bit per player, and we present a perfect quantum protocol for it. We prove that no classical protocol can succeed with a probability that differs from 1/2 by more than a fraction that is exponentially small in the number of players. This could be used to circumvent the detection loophole in experimental tests of nonlocality.

    African swine fever (ASF) is a devastating disease of domestic pigs. It is a socioeconomically important disease, initially described from Kenya, but subsequently reported in most Sub-Saharan countries. ASF spread to Europe, South America and the Caribbean through multiple introductions which were initially eradicated—except for Sardinia—followed by re‑introduction into Europe in 2007. In this study of ASF within the Democratic Republic of the Congo, 62 domestic pig samples, collected between 2005–2012, were examined for viral DNA and sequencing at multiple loci: C-terminus of the B646L gene (p72 protein), central hypervariable region (CVR) of the B602L gene, and the E183L gene (p54 protein). Phylogenetic analyses identified three circulating genotypes: I (64.5% of samples), IX (32.3%), and XIV (3.2%). This is the first evidence of genotypes IX and XIV within this country. Examination of the CVR revealed high levels of intra-genotypic variation, with 19 identified variants. PMID:28218698

    Sequence characterization of the near full-length genomes of HIV-1 isolates BCF-Dioum and BCF-Kita, originating from the Democratic Republic of Congo (DRC), was continued. These NED panel isolates, contributed by F. Brun-Vezinet (ENVA-France), were first identified as subtypes G and H, respectively. Our earlier analyses of portions of their pol genes showed that both were likely to be intersubtype recombinants of different composition. This study analyzed the remainder of each genome, confirming them to be complex recombinants. The BCF-Dioum genome resembles CRF06_cpx strains found in West Africa, composed of subtypes A/G/J/K. The BCF-Kita genome is a unique complex recombinant A-F-G-H-K-U strain. These data support previous observations of the complexity of strains originating from the DRC. BCF-Dioum may be a suitable strain for standards and reagents since it matches a defined circulating recombinant form. Studies and reagents made from BCF-Kita should take into account its complex genome.

PCRRFLP generated with two restriction enzymes (Nla III and Fnu 4HI in PCR-amplified ITS products for classifying strains into different lineages. The diagnosis performance of the indirect immune-fluorescence-monoclonal antibody (IFI-AcM was defined in comparison with real-time PCR as the gold standard. Results. Out of 242 HIV-infected patients, using the real-time PCR, the prevalence of E. bieneusi was 7.9% (n=19 among the 19 E. bieneusi, one was coinfected with E. intestinalis. In 19 E. bieneusi persons using PCR-RFLP method, 5 type I strains of E. bieneusi (26.3% and 5 type IV strains of E. bieneusi (26.3% were identified. The sensitivity of IFI-AcM was poor as estimated 42.1%. Conclusion. Despite different PCR methods, there is possible association between HIVinfection, geographic location (France, Cameroun, Democratic Republic of Congo, and the concurrence of type I and type IV strains.

    The present External Quality Assessment (EQA) assessed microscopy of blood parasites among diagnostic laboratories in the Democratic Republic of the Congo. The EQA addressed 445 participants in 10/11 provinces (October 2013-April 2014). Participants were sent a panel of five slides and asked to return a routinely stained slide which was assessed for quality of preparation and staining. Response rate was 89.9% (400/445). For slide 1 (no parasites), 30.6% participants reported malaria, mostly Plasmodium falciparum. Only 11.0% participants reported slide 2 (Plasmodium malariae) correctly, 71.0% reported "malaria" or "Plasmodium falciparum" (considered acceptable). Slide 3 contained Plasmodium falciparum (109/μl) and Trypanosoma brucei brucei trypomastigotes: they were each reported by 32.5% and 16.5% participants respectively, 6.0% reported both. Slide 4 (Trypanosoma) was recognised by 44.9% participants. Slide 5 (Plasmodium ovale) was correctly reported by 6.2% participants, another 68.8% replied "malaria" or "Plasmodium falciparum" (considered acceptable). Only 13.6% of routine slides returned were correctly prepared and stained. The proportion of correct/acceptable scores for at least 4/5 slides was higher among EQA-experienced participants compared to first time participants (40.9% versus 22.4%, p = 0.001) and higher among those being trained microscopy including non-falciparum species and Trypanosoma was poor. Recent training and previous EQA participation were associated with a better performance.

    We propose a protocol for converting the encryption function of a ciphertext into another encryption function while keeping the corresponding message secret. The proposed protocol allows conversions of the El Gamal and Paillier cryptosystems and has the potential to design an efficient multiparty protocol intended for circuits consisting of arithmetic and logical operations. We clarify the condition of circuits such that the multiparty protocol based on the proposed protocol provides better performance than previous approaches. In addition, we introduce some privacy-preserving statistical computations as an effective application of the proposed protocol.

    In the Democratic Republic of the Congo the control of hypertension is poor, characterized by an increasing number of reported cases of hypertension related complications. Poor control of hypertension is associated with non-adherence to antihypertensive medication. It is well established that the use of complementary and alternative medicine is one of the main factors of non-adherence to antihypertensive medication. The aim of this study is to determine the prevalence and factors associated with the use of complementary and alternative medicine. A cross-sectional study was carried out at the Kinshasa Primary Health-care (KPHC) facilities network in November 2014. A structured interview questionnaire was administrated to a total of 280hypertensive patients. Complementary and alternative medicine were defined according to the National Institute of Health classification as a group of diverse medical and healthcare systems, practices, and products that are not presently considered to be part of conventional medicine. Data were summarized using proportion and mean (with standard deviation). The student's t test and χ(2) test were used respectively for mean and proportion comparison. Logistic regression analysis identified determinants of the use of complementary and alternative medicine. The prevalence of use of complementary and alternative medicine was 26.1% (95% CI: 20.7% - 31.8%).Determinants of use of complementary and alternative medicine included misperception about hypertension curability (OR = 2.1; 95%CI: 1.1-3.7) and experience of medication side effects (OR = 2.9; 95%CI: 1.7-5.1). The use of CAM for hypertensive patients is a major problem; antihypertensives with fewer side effects must be emphasized. Religious leaders must become involved in the communication for behavioral change activities to improve the quality of life for hypertensive patients.

    2009-08-01

    Full Text Available Abstract Background Very few data on anti-malarial efficacy are available from the Democratic Republic of Congo (DRC. DRC changed its anti-malarial treatment policy to amodiaquine (AQ and artesunate (AS in 2005. Methods The results of two in vivo efficacy studies, which tested AQ and sulphadoxine-pyrimethamine (SP monotherapies and AS+SP and AS+AQ combinations in Boende (Equatorial province, and AS+SP, AS+AQ and SP in Kabalo (Katanga province, between 2003 and 2004 are presented. The methodology followed the WHO 2003 protocol for assessing the efficacy of anti-malarials in areas of high transmission. Results Out of 394 included patients in Boende, the failure rates on day 28 after PCR-genotyping adjustment of AS+SP and AS+AQ were estimated as 24.6% [95% CI: 16.6–35.5] and 15.1% [95% CI: 8.6–25.7], respectively. For the monotherapies, failure rates were 35.9% [95% CI: 27.0–46.7] for SP and 18.3% [95% CI: 11.6–28.1] for AQ. Out of 207 patients enrolled in Kabalo, the failure rate on day 28 after PCR-genotyping adjustment was 0 [1-sided 95% CI: 5.8] for AS+SP and AS+AQ [1-sided 95% CI: 6.2]. It was 19.6% [95% CI: 11.4–32.7] for SP monotherapy. Conclusion The finding of varying efficacy of the same combinations at two sites in one country highlights one difficulty of implementing a uniform national treatment policy in a large country. The poor efficacy of AS+AQ in Boende should alert the national programme to foci of resistance and emphasizes the need for systems for the prospective monitoring of treatment efficacy at sentinel sites in the country.

    Full Text Available Between 2011 and 2013 the number of recorded malaria cases had more than doubled, and between 2009 and 2013 had increased almost 4-fold in MSF-OCA (Médecins sans Frontières – Operational Centre Amsterdam programmes in the Democratic Republic of the Congo (DRC. The reasons for this rise are unclear. Incorrect intake of Artemisinin Combination Therapy (ACT could result in failure to treat the infection and potential recurrence. An adherence study was carried out to assess whether patients were completing the full course of ACT. One hundred and eight malaria patients in Shamwana, Katanga province, DRC were visited in their households the day after ACT was supposed to be completed. They were asked a series of questions about ACT administration and the blister pack was observed (if available. Sixty seven (62.0% patients were considered probably adherent. This did not take into account the patients that vomited or spat their pills or took them at the incorrect time of day, in which case adherence dropped to 46 (42.6%. The most common reason that patients gave for incomplete/incorrect intake was that they were vomiting or felt unwell (10 patients (24.4%, although the reasons were not recorded for 22 (53.7% patients. This indicates that there may be poor understanding of the importance of completing the treatment or that the side effects of ACT were significant enough to over-ride the pharmacy instructions. Adherence to ACT was poor in this setting. Health education messages emphasising the need to complete ACT even if patients vomit doses, feel unwell or their health conditions improve should be promoted.

    Full Text Available The European Union (EU is increasingly aspiring to be a global peace and security actor. Using the Democratic Republic of the Congo (DRC as a test case to analyse such ambitions, this article reveals that the EU’s attempts to build peace and security are severely compromised by its bureaucratic and organizational complexity as well as by its ineffective policies. In fact, the EU’s state-centred approach in the DRC has resulted in the EU’s inability to deal with 1 the realities of governance in the DRC and 2 the strong transborder dimensions of the conflict. As a result, the EU continues to lack a coherent strategy for the DRC, despite a large budget. The analysis concludes that the EU is more concerned with establishing a symbolic presence and a form of representation than with achieving specific goals.Die Europäische Union (EU bemüht sich zunehmend um eine anerkannte Rolle in der globalen Friedenssicherung. Die Autoren des vorliegenden Beitrags nehmen die Aktivitäten der EU in der Demokratischen Republik Kongo (DRC als Testfall und zeigen auf, dass die Umsetzung ihrer Versuche, dort Frieden und Sicherheit zu schaffen, von einer bürokratischen Herangehensweise, den komplexen EU-Strukturen und einer ineffizienten politischen Zielsetzung stark behindert wird. Tatsächlich hat der staatszentrierte Ansatz der EU dazu geführt, dass sie weder mit den Realitäten des Regierens in der DRC, noch mit den entscheidenden grenzüberschreitenden Dimensionen des Konflikts umzugehen wusste. Im Ergebnis fehlt der EU weiterhin eine kohärente Strategie für die DRC – trotz eines beträchtlichen Budgets. Die Autoren kommen zu dem Schluss, dass es der EU mehr darum geht, eine symbolische Präsenz zu etablieren, als spezifische Ziele zu erreichen.

    All healthcare providers decide in someone else's place, for someone else. In doing so, they take their place in a long long tradition, that of medical paternalism. Patients are treated as children, incapable of making decisions about themselves. How then are we supposed to deal with patients like the street children of the Democratic Republic of the Congo, who are not part of our health-care system, who refuse care and prescriptions? Their refusal of caregivers forces us to seek strategies to dispel the conflicts, adapt outselves to the situation (self-medication, drug sales outside of dispensaries, etc.), but especially to rethink the relation between caregivers and patients. This does not mean abandoning the authoritarian patriarchal model for total relativism; the use of drugs such as antibiotics is and must remain surrounded by all the precautions necessary to avoid the further development of resistance; it does mean training and informing. The task facing us is that of health education and promotion, a long and continuous process, centered on patients and integrated with their care, aimed at making them capable of managing their disease. This procedure is part of a pragmatic approach: beyond the asymmetry involved in any relationship of power, it is essential to establish informed confidence, to look for adhesion and not constraint. Only this pragmatism can incite young people with sexually transmitted diseases (STDs) to use modern medicine and comply with the dosage instructions. Effective treatment of STDs is, according to WHO, one of the most powerful weapons in the battle against AIDS transmission.

  7. External quality assessment of reading and interpretation of malaria rapid diagnostic tests among 1849 end-users in the Democratic Republic of the Congo through Short Message Service (SMS.

    Directory of Open Access Journals (Sweden)

    Pierre Mukadi

    Full Text Available BACKGROUND: Although malaria rapid diagnostic tests (RDT are simple to perform, they remain subject to errors, mainly related to the post-analytical phase. We organized the first large scale SMS based external quality assessment (EQA on correct reading and interpretation of photographs of a three-band malaria RDT among laboratory health workers in the Democratic Republic of the Congo (DR Congo. METHODS AND FINDINGS: High resolution EQA photographs of 10 RDT results together with a questionnaire were distributed to health facilities in 9 out of 11 provinces in DR Congo. Each laboratory health worker answered the EQA by Short Message Service (SMS. Filled-in questionnaires from each health facility were sent back to Kinshasa. A total of 1849 laboratory health workers in 1014 health facilities participated. Most frequent errors in RDT reading were i failure to recognize invalid (13.2-32.5% or negative test results (9.8-12.8%, (ii overlooking faint test lines (4.1-31.2% and (iii incorrect identification of the malaria species (12.1-17.4%. No uniform strategy for diagnosis of malaria at the health facility was present. Stock outs of RDTs occurred frequently. Half of the health facilities had not received an RDT training. Only two thirds used the RDT recommended by the National Malaria Control Program. Performance of RDT reading was positively associated with training and the technical level of health facility. Facilities with RDT positivity rates >50% and located in Eastern DR Congo performed worse. CONCLUSIONS: Our study confirmed that errors in reading and interpretation of malaria RDTs are widespread and highlighted the problem of stock outs of RDTs. Adequate training of end-users in the application of malaria RDTs associated with regular EQAs is recommended.

    Introduction People living in poverty have limited access to traditional financial institutions. Microfinance programmes are designed to meet this gap and show promise in improving income, economic productivity and health. Our Congolese–US community academic research partnership developed two livestock productive asset transfer programmes, Pigs for Peace (PFP) and Rabbits for Resilience (RFR), to address the interlinked health, social and economic well-being of individuals, their families and communities. The community-based randomised controlled trials examine the effectiveness of PFP and RFR to improve health, economic stability, and family and community relationships among male and female adults and adolescents living in 10 rural, postconflict villages of eastern Democratic Republic of Congo. Methods and analysis PFP participants include adult permanent residents of rural villages; adolescent participants in RFR include male and female adolescents 10–15 years old living in the selected rural villages. Participants were randomised to intervention or delayed control group. Participants in PFP completed baseline interview prior to intervention and follow-up interview at 6, 12 and 18 months postintervention. In RFR, participants completed baseline interview prior to intervention and follow-up interview at 6, 12 and 18 months postbaseline. The primary outcome of both trials, the change in baseline mental health distress at 18 months in the intervention group (adults, adolescents) compared to control group, is used to calculate sample size. Ethics and dissemination The Johns Hopkins Medical Institute Internal Review Board approved this protocol. A committee of respected Congolese educators and community members (due to lack of local ethics review board) approved the study. The findings will provide important information on the potential for community-led sustainable development initiatives to build on traditional livelihood (livestock raising, agriculture

  9. Food insecurity is associated with increased risk of non-adherence to antiretroviral therapy among HIV-infected adults in the Democratic Republic of Congo: a cross-sectional study.

    Full Text Available BACKGROUND: Food insecurity is increasingly reported as an important barrier of patient adherence to antiretroviral therapy (ART in both resource-poor and rich settings. However, unlike in resource rich-settings, very few quantitative studies to date have investigated the association of food insecurity with patient adherence to ART in Sub-Saharan Africa. The current study examines the association between food insecurity and adherence to ART among HIV-infected adults in the Democratic Republic of Congo (DRC. METHODS AND FINDINGS: This is a cross-sectional quantitative study of patients receiving ART at three private and one public health facilities in Kinshasa, DRC. Participants were consecutively recruited into the study between April and November 2012. Adherence was measured using a combined method coupling pharmacy refill and self-reported adherence. Food insecurity was the primary predictor, and was assessed using the Household Food Insecurity Access Scale (HFIAS. Of the 898 participants recruited into the study, 512 (57% were food insecure, and 188 (20.9% were not adherent to ART. Food insecurity was significantly associated with non-adherence to ART (AOR, 2.06; CI, 1.38-3.09. We also found that perceived harmfulness of ART and psychological distress were associated respectively with increased (AOR, 1.95; CI, 1.15-3.32 and decreased (AOR, 0.31; CI, 0.11-0.83 odds of non-adherence to ART. CONCLUSION: Food insecurity is prevalent and a significant risk factor for non-adherence to ART among HIV-infected individuals in the DRC. Our findings highlight the urgent need for strategies to improve food access among HIV-infected on ART in order to ensure patient adherence to ART and ultimately the long-term success of HIV treatment in Sub-Saharan Africa.

  10. Efficacy of fixed-dose combination artesunate-amodiaquine versus artemether-lumefantrine for uncomplicated childhood Plasmodium falciparum malaria in Democratic Republic of Congo: a randomized non-inferiority trial

    Full Text Available Abstract Background In 2005, the Democratic Republic of Congo (DRC adopted artesunate and amodiaquine (ASAQ as first-line anti-malarial treatment. In order to compare the efficacy of the fixed-dose formulation ASAQ versus artemether-lumefantrine (AL, a randomized, non-inferiority open-label trial was conducted in Katanga. Methods Children aged six and 59 months with uncomplicated Plasmodium falciparum malaria were enrolled and randomly allocated into one of the two regimens. The risk of recurrent parasitaemia by day 42, both unadjusted and adjusted by PCR genotyping to distinguish recrudescence from new infection, was analysed. Results Between April 2008 and March 2009, 301 children were included: 156 with ASAQ and 145 with AL. No early treatment failures were reported. Among the 256 patients followed-up at day 42, 32 patients developed late clinical or parasitological failure (9.9% (13/131 in the ASAQ group and 15.2% (19/125 in the AL group. After PCR correction, cure rates were 98.3% (95%CI, 94.1-99.8 in the ASAQ group and 99.1% (95%CI, 94.9-99.9 in the AL group (difference −0.7%, one sided 95% CI −3.1. Kaplan-Meier PCR-adjusted cure rates were similar. Both treatment regimens were generally well tolerated. Conclusion Both ASAQ and AL are highly effective and currently adequate as the first-line treatment of uncomplicated falciparum malaria in this area of Katanga, DRC. However, in a very large country, such as DRC, and because of possible emergence of resistance from other endemic regions, surveillance of efficacy of artemisinin-based combination treatments, including other evaluations of the resistance of ASAQ, need to be done in other provinces. Trial registration The protocol was registered with the clinicaltrials.gov, open clinical trial registry under the identifier number NCT01567423.

The latter would give people a wider scope of things to vote on. In practice, no doubt there is room to do much more of both. But whereas it would be democratically justifiable in an ideal world for democracy to be completely unbounded as regards range, even in an ideal world democracy ought be subject to some limits internal to the logic of democracy itself as regards its scope.

    In this protocol we describe a mixed methods study in the province of South Kivu, Democratic Republic of Congo evaluating the effectiveness of different demand side strategies to increase maternal health service utilization and the practice of birth spacing. Conditional service subsidization, conditional cash transfers and non-monetary incentives aim to encourage women to use maternal health services and practice birth spacing in two different health districts. Our methodology will comparatively evaluate the effectiveness of different approaches against each other and no intervention. This study comprises four main research activities: 1) Formative qualitative research to determine feasibility of planned activities and inform development of the quantitative survey; 2) A community-based, longitudinal survey; 3) A retrospective review of health facility records; 4) Qualitative exploration of intervention acceptability and emergent themes through in-depth interviews with program participants, non-participants, their partners and health providers. Female community health workers are engaged as core members of the research team, working in tandem with female survey teams to identify women in the community who meet eligibility criteria. Female community health workers also act as key informants and community entry points during methods design and qualitative exploration. Main study outcomes are completion of antenatal care, institutional delivery, practice of birth spacing, family planning uptake and intervention acceptability in the communities. Qualitative methods also explore decision making around maternal health service use, fertility preference and perceptions of family planning. The innovative mixed methods design allows quantitative data to inform the relationships and phenomena to be explored in qualitative collection. In turn, qualitative findings will be triangulated with quantitative findings. Inspired by the principles of grounded theory, qualitative

    The global health community has recognized that expanding the contraceptive method mix is a programmatic imperative since (1) one-third of unintended pregnancies are due to method failure or discontinuation, and (2) the addition of a new method to the existing mix tends to increase total contraceptive use. Since July 2011, CARE has been implementing the Supporting Access to Family Planning and Post-Abortion Care (SAFPAC) initiative to increase the availability, quality, and use of contraception, with a particular focus on highly effective and long-acting reversible methods-intrauterine devices (IUDs) and implants-in crisis-affected settings in Chad and the Democratic Republic of the Congo (DRC). This initiative supports government health systems at primary and referral levels to provide a wide range of contraceptive services to people affected by conflict and/or displacement. Before the initiative, long-acting reversible methods were either unknown or unavailable in the intervention areas. However, as soon as trained providers were in place, we noted a dramatic and sustained increase in new users of all contraceptive methods, especially implants, with total new clients reaching 82,855, or 32% of the estimated number of women of reproductive age in the respective catchment areas in both countries, at the end of the fourth year. Demand for implants was very strong in the first 6 months after provider training. During this time, implants consistently accounted for more than 50% of the method mix, reaching as high as 89% in Chad and 74% in DRC. To ensure that all clients were getting the contraceptive method of their choice, we conducted a series of discussions and sought feedback from different stakeholders in order to modify program strategies. Key program modifications included more focused communication in mass media, community, and interpersonal channels about the benefits of IUDs while reinforcing the wide range of methods available and refresher training for

    People living in poverty have limited access to traditional financial institutions. Microfinance programmes are designed to meet this gap and show promise in improving income, economic productivity and health. Our Congolese-US community academic research partnership developed two livestock productive asset transfer programmes, Pigs for Peace (PFP) and Rabbits for Resilience (RFR), to address the interlinked health, social and economic well-being of individuals, their families and communities. The community-based randomised controlled trials examine the effectiveness of PFP and RFR to improve health, economic stability, and family and community relationships among male and female adults and adolescents living in 10 rural, postconflict villages of eastern Democratic Republic of Congo. PFP participants include adult permanent residents of rural villages; adolescent participants in RFR include male and female adolescents 10-15 years old living in the selected rural villages. Participants were randomised to intervention or delayed control group. Participants in PFP completed baseline interview prior to intervention and follow-up interview at 6, 12 and 18 months postintervention. In RFR, participants completed baseline interview prior to intervention and follow-up interview at 6, 12 and 18 months postbaseline. The primary outcome of both trials, the change in baseline mental health distress at 18 months in the intervention group (adults, adolescents) compared to control group, is used to calculate sample size. The Johns Hopkins Medical Institute Internal Review Board approved this protocol. A committee of respected Congolese educators and community members (due to lack of local ethics review board) approved the study. The findings will provide important information on the potential for community-led sustainable development initiatives to build on traditional livelihood (livestock raising, agriculture) to have a sustained health, economic and social impact on the

    Social accountability has to be configured according to the context in which it operates. This paper aimed to identify local contextual factors in two health zones in the Democratic Republic of the Congo and discuss their possible influences on shaping, implementing and running social accountability initiatives. Data on local socio-cultural characteristics, the governance context, and socio-economic conditions related to social accountability enabling factors were collected in the two health zones using semi-structured interviews and document reviews, and were analyzed using thematic analysis. The contexts of the two health zones were similar and characterized by the existence of several community groups, similarly structured and using similar decision-making processes. They were not involved in the health sector's activities and had no link with the health committee, even though they acknowledged its existence. They were not networked as they focused on their own activities and did not have enough capacity in terms of social mobilization or exerting pressure on public authorities or providers. Women were not perceived as marginalized as they often occupied other positions in the community besides carrying out domestic tasks and participated in community groups. However, they were still subject to the local male dominance culture, which restrains their involvement in decision-making, as they tend to be less educated, unemployed and suffer from a lack of resources or specific skills. The socio-economic context is characterized by subsistence activities and a low employment rate, which limits the community members' incomes and increases their dependence on external support. The governance context was characterized by imperfect implementation of political decentralization. Community groups advocating community rights are identified as "political" and are not welcomed. The community groups seemed not to be interested in the health center's information and had no access

    A novel multi-party quantum steganography protocol based on quantum secret sharing is proposed in this paper. Hidden channels are built in HBB and improved HBB quantum secret sharing protocols for secret messages transmitting, via the entanglement swapping of GHZ states and Bell measurement. Compared with the original protocol, there are only a few different GHZ sates transmitted in the proposed protocol, making the hidden channel with good imperceptibility. Moreover, the secret messages keep secure even when the hidden channel is under the attack from the dishonest participators, for the sub-secretmessages distributed randomly to different participators. With good imperceptibility and security, the capacity of proposed protocol is higher than previous multi-party quantum steganography protocol.

    We propose an efficient framework for enabling secure multi-party numerical computations in a Peer-to-Peer network. This problem arises in a range of applications such as collaborative filtering, distributed computation of trust and reputation, monitoring and numerous other tasks, where the computing nodes would like to preserve the privacy of their inputs while performing a joint computation of a certain function. Although there is a rich literature in the field of distributed systems security concerning secure multi-party computation, in practice it is hard to deploy those methods in very large scale Peer-to-Peer networks. In this work, we examine several possible approaches and discuss their feasibility. Among the possible approaches, we identify a single approach which is both scalable and theoretically secure. An additional novel contribution is that we show how to compute the neighborhood based collaborative filtering, a state-of-the-art collaborative filtering algorithm, winner of the Netflix progress ...

Notably, it is necessary only for any one party to publish classical information. Consequently, the efficacy of the method is independent of the relative location of the parties. The suggested protocol is robust and does not require precise sequencing of procedural steps.

    Multipartite quantum correlations are important resources for the development of quantum information and computation protocols. However, the resourcefulness of multipartite quantum correlations in practical settings is limited by its fragility under decoherence due to environmental interactions. Though there exist protocols to protect bipartite entanglement under decoherence, the implementation of such protocols for multipartite quantum correlations has not been sufficiently explored. Here, we study the effect of local amplitude damping channel on the generalized Greenberger–Horne–Zeilinger state, and use a protocol of optimal reversal quantum weak measurement to protect the multipartite quantum correlations. We observe that the weak measurement reversal protocol enhances the robustness of multipartite quantum correlations. Further it increases the critical damping value that corresponds to entanglement sudden death. To emphasize the efficacy of the technique in protection of multipartite quantum correlation, we investigate two proximately related quantum communication tasks, namely, quantum teleportation in a one sender, many receivers setting and multiparty quantum information splitting, through a local amplitude damping channel. We observe an increase in the average fidelity of both the quantum communication tasks under the weak measurement reversal protocol. The method may prove beneficial, for combating external interactions, in other quantum information tasks using multipartite resources. - Highlights: • Extension of weak measurement reversal scheme to protect multiparty quantum correlations. • Protection of multiparty quantum correlation under local amplitude damping noise. • Enhanced fidelity of quantum teleportation in one sender and many receivers setting. • Enhanced fidelity of quantum information splitting protocol.

  5. Strong polygamy of quantum correlations in multi-party quantum systems

    We propose a new type of polygamy inequality for multi-party quantum entanglement. We first consider the possible amount of bipartite entanglement distributed between a fixed party and any subset of the rest parties in a multi-party quantum system. By using the summation of these distributed entanglements, we provide an upper bound of the distributed entanglement between a party and the rest in multi-party quantum systems. We then show that this upper bound also plays as a lower bound of the usual polygamy inequality, therefore the strong polygamy of multi-party quantum entanglement. For the case of multi-party pure states, we further show that the strong polygamy of entanglement implies the strong polygamy of quantum discord.

The changes concerning education certainly that include the school as an institution that organized manner, specified forms and methods training and preparing young people for life and work in more developed and democratic society. I believe that education as a social category should always be updated with social change and of course that in a democratic society should be democratic education. Democratization of society requires and democratization of the school, which in turn inevitably overemphasizes individually oriented model of education. Only with such an model of education can apply the principles of humanity, individuality, diversity education and respect for of the personal interests of students. Within the democratic life in school and preparing young people for democratic life and the need for a working of student parliaments, contemporary school and the characteristics of that school, are one of the basic things about functioning of the democratic life of the school. Democratization of education is not a new and unfamiliar requirement in developed countries as well as in our country. Since the beginning of the independence of the Republic of Macedonia are talking about the democratization of education, upbringing for democracy, basic for Democracy, civil education, etc.. Still until today still do not have comprehensive research relevant to this issue. Young people are not sufficiently prepared for democratic behavior, working and living in a democratic society.

    In this paper, we attempt to revisit the problem of multi-party conferencing from a practical perspective, and to rethink the design space involved in this problem. We believe that an emphasis onlow end-to-end delays between any two parties in the conference is a must, and the source sending rate in a session should adapt to bandwidth availability and congestion. We present Celerity, a multi-party conferencing solution specifically designed to achieve our objectives. It is entirely Peer-to-Peer (P2P), and as such eliminating the cost of maintaining centrally administered servers. It is designed to deliver video with low end-to-end delays, at quality levels commensurate with available network resources over arbitrary network topologies where bottlenecks can be anywhere in the network. This is in contrast to commonly assumed P2P scenarios where bandwidth bottlenecks reside only at the edge of the network. The highlight in our design is a distributed and adaptive rate control protocol, that can discover and adap...

    Monogamy of quantum correlation measures puts restrictions on the sharability of quantum correlations in multiparty quantum states. Multiparty quantum states can satisfy or violate monogamy relations with respect to given quantum correlations. We show that all multiparty quantum states can be made monogamous with respect to all measures. More precisely, given any quantum correlation measure that is non-monogamic for a multiparty quantum state, it is always possible to find a monotonically increasing function of the measure that is monogamous for the same state. The statement holds for all quantum states, whether pure or mixed, in all finite dimensions and for an arbitrary number of parties. The monotonically increasing function of the quantum correlation measure satisfies all the properties that are expected for quantum correlations to follow. We illustrate the concepts by considering a thermodynamic measure of quantum correlation, called the quantum work deficit.

  14. Secure multi-party computation solution to Yao's millionaires' problem based on set-inclusion

    2005-01-01

    Secure multi-party computation is a focus of international cryptography in recent years. Protocols for Yao's millionaires' problem have become an important building block of many secure multi-party computation protocols. Their efficiency are crucial to the efficiency of many secure multi-party computation protocols. Unfortunately, known protocols for Yao's millionaires' problem have high computational complexity or communication complexity. In this study, based on the 1-out-of-m oblivious transfer and set-inclusion problem, we propose a new protocol to solve this problem. This new protocol is very efficient in terms of both computational and communication complexities. Its privacy-preserving property is also proved by simulation paradigm which is generally accepted in the study of secure multi-party computation. We also compare the information leakage of our new protocol and the known protocols.

  15. Efficient generation of photonic entanglement and multiparty quantum communication

    Energy Technology Data Exchange (ETDEWEB)

    Trojek, Pavel

    2007-09-15

    This thesis deals largely with the problem of efficient generation of photonic entanglement with the principal aim of developing a bright source of polarization-entangled photon pairs, which meets the requirements for reliable and economic operation of quantum communication prototypes and demonstrators. Our approach uses a cor-related photon-pair emission in nonlinear process of spontaneous parametric downconversion pumped by light coming from a compact and cheap blue laser diode. Two alternative source configurations are examined within the thesis. The first makes use of a well established concept of degenerate non-collinear emission from a single type-II nonlinear crystal and the second relies on a novel method where the emissions from two adjacent type-I phase-matched nonlinear crystals operated in collinear non-degenerate regime are coherently overlapped. The latter approach showed to be more effective, yielding a total detected rate of almost 10{sup 6} pairs/s at >98% quantum interference visibility of polarization correlations. The second issue addressed within the thesis is the simplification and practical implementation of quantum-assisted solutions to multiparty communication tasks. We show that entanglement is not the only non-classical resource endowing the quantum multiparty information processing its power. Instead, only the sequential communication and transformation of a single qubit can be sufficient to accomplish certain tasks. This we prove for two distinct communication tasks, secret sharing and communication complexity. Whereas the goal of the first is to split a cryptographic key among several parties in a way that its reconstruction requires their collaboration, the latter aims at reducing the amount of communication during distributed computational tasks. Importantly, our qubitassisted solutions to the problems are feasible with state-of-the-art technology. This we clearly demonstrate in the laboratory implementation for 6 and 5 parties

    We present a protocol for multi-party superdense coding by using multi-atom in cavity quantum electrodynamics (QED). It is shown that, with a highly detuned cavity mode and a strong driving field, the protocol is insensitive to both cavity decay and thermal field. It is even certain to identify GHZ states via detecting the atomic states. Therefore we can realize the quantum dense coding in a simple way in the multiparty system.

    A (n, n )-threshold scheme of multiparty quantum secret sharing of classical or quantum message is proposed based on the discrete quantum Fourier transform.In our proposed scheme, the secret message, which is encoded by using the forward quantum Fourier transform and decoded by using the reverse, is split and shared in such a way that it can be reconstructed among them only if all the participants work in concert.Furthermore, we also discuss how this protocol must be carefully designed for correcting errors and checking eavesdropping or a dishonest participant.Security analysis shows that our scheme is secure.Also, this scheme has an advantage that it is completely compatible with quantum computation and easier to realize in the distributed quantum secure computation.

    Recently, Gao et al.'s [Commun. Theor. Phys. 52 (2009) 421] multiparty quantum secret sharing (MQSS) protocol with two-photon three-dimensional Bell states was enhanced by Hwang et al. [Commun. Theor. Phys. 56 (2011) 79]. The improved protocol removes some unnecessary unitary operations, devices, and transmissions by the technique of decoy single photons and careful modification. However, in this paper, we investigate the security of the improved protocol and find it is insecure. The eavesdropper can steal all Alice's secret information. Furthermore, a feasible modification to remedy the security loophole is put forward. Our improved protocol provides a basic method to modify a kind of MQSS protocols which cannot resist the collusion attack.

    Two multiparty simultaneous quantum identity authentication (MSQIA) protocols based on secret sharing are presented. All the users can be authenticated by a trusted third party (TTP) simultaneously. In the first protocol,the TTP shares a random key K with all the users using quantum secret sharing. The ith share acts as the authentication key of the ith user. When it is necessary to perform MSQIA,the TTP generates a random number R secretly and sends a sequence of single photons encoded with K and R to all the users. According to his share,each user performs the corresponding unitary operations on the single photon sequence sequentially. At last,the TTP can judge whether the impersonator exists. The sec-ond protocol is a modified version with a circular structure. The two protocols can be efficiently used for MSQIA in a network. They are feasible with current technol-ogy.

The country covers a territory of 1,267,000 square kilometers (489,191 square miles), or about three times the size of California, with a population exceeding 7.5 million people. In 1989, Niger abandoned 16 years of military rule and is now on the way to a democratic system; the first multiparty elections are schedules for 1992. Mining industries are the primary base for Niger`s economy. Uranium is the leading export commodity, with revenues accounting for about one-third of Niger`s export earnings. Other mineral products include coal, tin, and small amounts of gold.

    This study examined regret following HIV serostatus disclosure and associated factors in under-investigated contexts (Mali, Morocco, Democratic Republic of the Congo, Ecuador and Romania). A community-based cross-sectional study was implemented by a mixed consortium [researchers/community-based organizations (CBO)]. Trained CBO members interviewed 1,500 PLHIV in contact with CBOs using a 125-item questionnaire. A weighted multivariate logistic regression was performed. Among the 1,212 participants included in the analysis, 290 (23.9 %) declared that disclosure was a mistake. Female gender, percentage of PLHIV's network knowing about one's seropositivity from a third party, having suffered rejection after disclosure, having suffered HIV-based discrimination at work, perceived seriousness of infection score, daily loneliness, property index and self-esteem score were independently associated with regret. Discrimination, as well as individual characteristics and skills may affect the disclosure experience. Interventions aiming at improving PLHIV skills and reducing their social isolation may facilitate the disclosure process and avoid negative consequences.

    2015-08-01

    Key management plays a fundamental role in the field of cryptography. In this paper, we propose a novel multiparty quantum key management (QKM) protocol. Departing from single-function quantum cryptography protocols, our protocol has a salient feature in that it accomplishes a complete QKM process. In this process, we can simultaneously realize the functions of key generation, key distribution and key backup by executing the protocol once. Meanwhile, for the first time, we propose the idea of multi-function QKM. Firstly, the secret key is randomly generated by managers via the quantum measurements in -level Bell basis. Then, through entanglement swapping, the secret key is successfully distributed to users. Under circumstances of urgent requirement, all managers can cooperate to recover the users' secret key, but neither of them can recover it unilaterally. Furthermore, this protocol is further generalized into the multi-manager and multi-user QKM scenario. It has clear advantages in the burgeoning area of quantum security group communication. In this system, all group members share the same group key, and group key management is the foundation of secure group communication and hence an important subject of study.

Our main idea is to transform the outsourced data respectively encrypted by different users’ public keys to the ones that are encrypted by the same two private keys of the two assisted servers so that it is feasible to operate on the transformed ciphertexts to compute an encrypted result following the function to be computed. In order to keep the privacy of the result, the two servers cooperatively produce a custom-made result for each user that is authorized to get the result so that all authorized users can recover the desired result while other unauthorized ones including the two servers cannot. Compared with previous research, our protocol is completely noninteractive between any users, and both of the computation and the communication complexities of each user in our solution are independent of the computing function.

    2010-01-01

    In secure multi-party computation $n$ parties jointly evaluate an $n$-variate function $f$ in the presence of an adversary which can corrupt up till $t$ parties. Almost all the works that have appeared in the literature so far assume the presence of authenticated channels between the parties. This assumption is far from realistic. Two directions of research have been borne from relaxing this (strong) assumption: (a) The adversary is virtually omnipotent and can control all the communication channels in the network, (b) Only a partially connected topology of authenticated channels is guaranteed and adversary controls a subset of the communication channels in the network. This work introduces a new setting for (unconditional) secure multiparty computation problem which is an interesting intermediate model with respect to the above well studied models from the literature (by sharing a salient feature from both the above models). We consider the problem of (unconditional) secure multi-party computation when 'some...

    2017-05-01

    Monogamy is a nonclassical property that limits the distribution of quantum correlation among subparts of a multiparty system. We show that monogamy scores for different quantum correlation measures are bounded above by functions of genuine multipartite entanglement for a large majority of pure multiqubit states. The bound is universal for all three-qubit pure states. We derive necessary conditions to characterize the states that violate the bound, which can also be observed by numerical simulation for a small set of states, generated Haar uniformly. The results indicate that genuine multipartite entanglement restricts the distribution of bipartite quantum correlations in a multiparty system.

    Background The study aimed to identify the impact of non-disclosure of HIV status on the loss to follow-up (LTFU) of patients receiving anti-retroviral therapy. Methodology A historic cohort of HIV patients from 2 major hospitals in Goma, Democratic Republic of Congo was followed from 2004 to 2012. LTFU was defined as not taking an ART refill for a period of 3 months or longer since the last attendance, and had not yet been classified as ‘dead’ or ‘transferred-out’. Kaplan-Meier plots were used to determine the probability of LTFU as a function of time as inclusive of the cohort. The log-rank test was used to compare survival curves based on determinants. Cox proportional hazard modeling was used to measure predictors of LTFU from the time of treatment induction until December 15th, 2012 (the end-point). Results The median follow-up time was 3.99 years (IQR = 2.33 to 5.59). Seventy percent of patients had shared their HIV status with others (95% CI: 66.3–73.1). The proportion of LTFU was 12% (95%CI: 9.6–14.4). Patients who did not share their HIV status (Adjusted HR 2.28, 95% CI 1.46–2.29), patients who did not live in the city of Goma (Adjusted HR 1.97, 95% CI 1.02–3.77), and those who attained secondary or higher education level (Adjusted HR 1.60, 95% CI 1.02–2.53) had a higher hazard of being LTFU. Conclusion This study shows the relationship between the non–disclosure HIV status and LTFU. Healthcare workers in similar settings should pay more attention to clients who have not disclosed their HIV status, and to those living far from health settings where they receive medication.

  20. Women of the Second Republic and the Civil War from the present-day democratic perspective | Las mujeres de la República y la Guerra Civil desde la perspectiva democrática actual

    Full Text Available The strong social interest which women of the Second Republic and the civil war arouse, together with the wealth of solid historical works with a gender perspective, justify female experiences having a place in the debate on the memory of these two periods. The survival to the present day of stereotypes and myths about Republican women, despite the historiographical progress, has served to consolidate a depoliticized view of the past, which presents women as heroines without a clear ideological profile and as innocent victims of the changes and upheaval of the 1930s. These myths and stereotypes, which emphasize the idea of change experienced by women, rather than continuity and resistance to change, have influenced the current perception of the extension of female citizenship in Spanish society. | El especial interés social que las mujeres de la República y la Guerra Civil despiertan, así como la existencia de una nutrida y sólida historiografía de género justifican que las experiencias femeninas ocupen un lugar en el debate sobre la memoria de estos dos periodos. La pervivencia, en la actualidad, de estereotipos y mitos sobre las mujeres republicanas, a pesar de los avances historiográficos, contribuye a consolidar una visión despolitizada del pasado, que presenta a las mujeres como heroínas sin un perfil ideológico claro y víctimas inocentes de las transformaciones y convulsiones de los años treinta. Estos mitos y estereotipos, que refuerzan la idea del cambio experimentado por las mujeres, olvidando las permanencias y las resistencias al mismo, influyen en la percepción actual sobre la ampliación de la ciudadanía femenina en la sociedad española.

  8. Reunification, democratization and education

    Science.gov (United States)

    Lee, Jee-Hun

    1990-06-01

    The division of the nation into two separate political entities and the later development of dependent capitalism in South Korea have created two important eductional tasks, to do with reunification and democratization. Reunification requires liberation from the influence of foreign powers involved in the national partition and the development of dependent capitalism. Reunification-oriented education emphasizes understanding foreign influences in every sphere of the people's life, understanding the true realities of the two Koreas which have developed in different ways, and overcoming anti-communist ideological obfuscation. Democratization implies the enhancement of people's participation in the exercise and control of political and economic power at every level. For this purpose people need to be educated to participate in order to prevent the abuse of highly centralized power. United and collective action by teachers is required to protect schools from the state monopoly in education and to maintain the integrity and independence of a teaching profession so that pupils can learn and practise democratic values at school.

    Directory of Open Access Journals (Sweden)

    Ángeles González Fernández

    2007-12-01

    Full Text Available The attitude of the business community towards the Second Republic in the 1930s and the transition to democracy in the 1970s was remarkably similar, despite the fact that these were different models of change, with different political and socio-economic contexts. This similarity stems from a common acceptance of democracy, although this was not unconditional. It had to be a form of democracy linked to a free market economy, capable of guaranteeing political stability, law and order, and private property, all of which did not necessarily entail opposition to redistributive policies – provided these were not at variance with the defence of their interests, which tended to coincide with the general interests of the Nation. The key lies not so much in the business community itself, but in the consensus that underpinned the democratic transition of the 1970s; in the willingness of the political actors to include the social partners in the agreement to establish a stable and solid institutional framework, based on a free market economy, and guaranteeing the business community adequate business prospects. | La actitud de los empresarios ante la II República y la transición democrática en los años setenta guarda una notable semejanza, pese a tratarse de dos modelos de cambio distintos y a la existencia de contextos políticos y económico-sociales diferentes. Una similitud que proviene de una común aceptación de la democracia, aunque no de forma incondicional. Ha de ser una democracia vinculada a la economía de libre mercado, capaz de garantizar la estabilidad política, el orden público y la propiedad privada, rasgos que no implican oposición a políticas redistributivas –siempre y cuando se hallen supeditadas al respeto y defensa de sus intereses, que suelen ser identificados con el interés general de la Nación–. La clave no reside tanto en los empresarios como en el carácter consensuado de la transición democrática de los a

    Cowell, Andrew J.; Haack, Jereme N.; McColgin, Dave W.

    2006-06-08

    This research is aimed at understanding the dynamics of collaborative multi-party discourse across multiple communication modalities. Before we can truly make sig-nificant strides in devising collaborative communication systems, there is a need to understand how typical users utilize com-putationally supported communications mechanisms such as email, instant mes-saging, video conferencing, chat rooms, etc., both singularly and in conjunction with traditional means of communication such as face-to-face meetings, telephone calls and postal mail. Attempting to un-derstand an individual’s communications profile with access to only a single modal-ity is challenging at best and often futile. Here, we discuss the development of RACE – Retrospective Analysis of Com-munications Events – a test-bed prototype to investigate issues relating to multi-modal multi-party discourse.

  17. Secure multi-party communication with quantum key distribution managed by trusted authority

    Energy Technology Data Exchange (ETDEWEB)

    Hughes, Richard John; Nordholt, Jane Elizabeth; Peterson, Charles Glen

    2017-06-14

    Techniques and tools for implementing protocols for secure multi-party communication after quantum key distribution ("QKD") are described herein. In example implementations, a trusted authority facilitates secure communication between multiple user devices. The trusted authority distributes different quantum keys by QKD under trust relationships with different users. The trusted authority determines combination keys using the quantum keys and makes the combination keys available for distribution (e.g., for non-secret distribution over a public channel). The combination keys facilitate secure communication between two user devices even in the absence of QKD between the two user devices. With the protocols, benefits of QKD are extended to multi-party communication scenarios. In addition, the protocols can retain benefit of QKD even when a trusted authority is offline or a large group seeks to establish secure communication within the group.

    2015-12-01

    W-state is an important resource for many quantum information processing tasks. In this paper, we for the first time propose a multi-party measurement-device-independent quantum key distribution (MDI-QKD) protocol based on W-state. With linear optics, we design a W-state analyzer in order to distinguish the four-qubit W-state. This analyzer constructs the measurement device for four-party MDI-QKD. Moreover, we derived a complete security proof of the four-party MDI-QKD, and performed a numerical simulation to study its performance. The results show that four-party MDI-QKD is feasible over 150 km standard telecom fiber with off-the-shelf single photon detectors. This work takes an important step towards multi-party quantum communication and a quantum network.

    2016-03-06

    The current Internet infrastructure is not able to support independent evolution and innovation at physical and network layer functionalities, protocols and services, while at same time supporting the increasing bandwidth demands of evolving and heterogeneous applications. This paper addresses this problem by proposing a completely democratized optical network infrastructure. It introduces the novel concepts of the optical white box and bare metal optical switch as key technology enablers for democratizing optical networks. These are programmable optical switches whose hardware is loosely connected internally and is completely separated from their control software. To alleviate their complexity, a multi-dimensional abstraction mechanism using software-defined network technology is proposed. It creates a universal model of the proposed switches without exposing their technological details. It also enables a conventional network programmer to develop network applications for control of the optical network without specific technical knowledge of the physical layer. Furthermore, a novel optical network virtualization mechanism is proposed, enabling the composition and operation of multiple coexisting and application-specific virtual optical networks sharing the same physical infrastructure. Finally, the optical white box and the abstraction mechanism are experimentally evaluated, while the virtualization mechanism is evaluated with simulation.

  6. Peer-to-Peer Secure Multi-Party Numerical Computation Facing Malicious Adversaries

    CERN Document Server

    Bickson, Danny; Dolev, Danny; Pinkas, Benny

    2009-01-01

    We propose an efficient framework for enabling secure multi-party numerical computations in a Peer-to-Peer network. This problem arises in a range of applications such as collaborative filtering, distributed computation of trust and reputation, monitoring and other tasks, where the computing nodes is expected to preserve the privacy of their inputs while performing a joint computation of a certain function. Although there is a rich literature in the field of distributed systems security concerning secure multi-party computation, in practice it is hard to deploy those methods in very large scale Peer-to-Peer networks. In this work, we try to bridge the gap between theoretical algorithms in the security domain, and a practical Peer-to-Peer deployment. We consider two security models. The first is the semi-honest model where peers correctly follow the protocol, but try to reveal private information. We provide three possible schemes for secure multi-party numerical computation for this model and identify a singl...

The amber is 22 million years old, which is 12 million years younger than Baltic amber. The brown coal seams are Miocene formations. The origin of the amber is resin from the Mesozoic conifer Cupressospermum saxonicum Mai. Insect inclusions are well preserved, 55 photographs are provided, showing samples of mosquitoes, spiders, beetles, flies and other insects, from insect groups Arachnida, Myriapoda, and Hexapoda. Each insect sample from the inclusions is described in detail by scientists from the Museum of Natural History in Berlin. Infrared spectrograms of different amber pieces are also analyzed and aspects of amber genesis in the Bitterfeld area are discussed.

    Objective:To investigate malaria prevalence and socio-economic conditions in East Timor. Methods: Blood samples were collected from 650 individuals distributed among six districts in East Timor. 434 and 216 individuals were sampled by passive and active case detection, respectively (PCD, ACD).Results: The results showed that the plasmodium infection prevalence was 18.9% with predominance ofPlasmodium falciparum(P. falciparum) infections (60.2%). The majority of cases were detected in children between 2-14 years old in both PCD and ACD. Participants residing in Same and Lospalos were at a higher risk of malaria. The percentage of infections associated to the lack of bed net use was twice as high as users (25.2% vs 12.5%). The prevalence of malaria among participants who lived in brick/cement houses (8.3%) was two times less than those who lived in other types of houses (3.7%). There was a significantly lower prevalence of infection detected in individuals living in complete housing constructions with absence of domestic animals in or near the houses.Conclusions:The major risk factors for malaria in East Timor are age, lack of bed net use, incomplete housing constructions and exposure to mosquitoes.

    The major predecessor to Ringen's and my own efforts to measure democratic quality in terms of the purpose of democracy is Robert Dahl's seminal book Polyarchy (1971). Measuring the quality of democracy requires two prior judgments: (1) making sure that, in terms of institutional characteristics, a country is sufficiently democratic, and that, as a minimum, it has universal suffrage, and (2) that its democracy has been uninterrupted for a minimum number of years. To an important extent, higher democratic quality can be attributed to institutional characteristics of consensus democracy, especially proportional representation.

  7. Is John Locke a democrat?

    DEFF Research Database (Denmark)

    Svensson, Palle

      Over recent years there has been a tendency to present John Locke as an equalitarian democrat (Ashcraft) and being close to the political views of the levellers (Waldron). This is not a completely new interpretation (Kendall, 1941), but contrasts with the prevalent view presented in textbooks...... (Holden, Held, Ball and Dagger) and monographs on Locke (Dunn, Parry, Marshall). In this paper a new approach to the democratic character of John Locke's political theory is suggested, as his Second Treatise is analysed with Robert A. Dahl's conceptual framework on assumptions for a democratic order...

  8. Democratic parenting: paradoxical messages in democratic parent education theories

    Science.gov (United States)

    Oryan, Shlomit; Gastil, John

    2013-06-01

    Some prominent parent education theories in the United States and other Western countries base their educational viewpoint explicitly on democratic values, such as mutual respect, equality and personal freedom. These democratic parenting theories advocate sharing power with children and including them in family decision making. This study presents a textual analysis of two such theories, the Adlerian model of parent education and the Parent Effectiveness Training (PET) model, as they are embodied in two original bestselling textbooks. Through content and argumentation analysis of these influential texts, this study examines the paradoxes inherent in these two theories when they articulate how to implement fully democratic principles within the parent-child relationship. We discover that in spite of their democratic rationale, both books offer communication practices that guide the child to modify misbehaviour, enforce parental power, and manipulate the child to make decisions that follow parental judgment, and thus do not endorse the use of a truly democratic parenting style. We suggest, as an alternative to the democratic parenting style, that parents be introduced to a guardianship management style, in which they do not share authority with children, but seek opportunities for enabling children to make more autonomous decisions and participate in more family decision making.

    The Democratic Republic of Congo has enormous economic potential thanks to its raw material wealth. However, since 1996 (if not before) DR Congo has been seen as a classic example of the linkage between the exploitation of raw materials and the financing of war. The UN Panel of Experts on the Illegal Exploitation of Natural Resources in DR Congo points out that the history of Congo since colonial times has been marked by systematic abuse of natural and human resources (UN Panel 2002). The UN Panel of Experts and the work of NGOs have helped to reveal rebels, senior military figures and private companies as profiteers from the exploitation of raw materials and to identify channels of financing the violent conflict in Congo since 1996 (see reports from the UN Panel, Pole Institute, Global Witness, HRW). Foreign companies mining, trading in or processing raw materials in DR Congo have also been regularly criticised as sharing responsibility for the ongoing violence, principally in the eastern Congo (UN Panel 2002, Cuvelier/Raeymaekers 2002, RAID 2004). Practically every major escalation in conflict in recent years between the various players in Congo has been connected to the management of, or the (legal or illegal) revenues from, natural resources, particularly from mining. This observation was also backed by data from the HIIK's CONIS information system. In 2008, eight of nine conflicts in Congo related at least in part to resources - five being violent and three non-violent (HIIK 2008). Following the coltan boom of 2000/2001, it now primarily profits from the mining and sale of the tin oxide ore cassiterite which continue to serve as the key means of financing violence (see Garrett 2008).1 In DRK it is not only the mining and sale of coltan and cassiterite which represents a nexus of conflict and resources however. Alongside timber, diamonds, oil and gold, it is above all the mining and sale of copper and cobalt from the so-called copper belt in the south

    To construct a quantum network with many end users, it is critical to have a cost-efficient way to distribute entanglement over different network ends. We demonstrate an entanglement access network, where the expensive resource, the entangled photon source at the telecom wavelength and the core communication channel, is shared by many end users. Using this cost-efficient entanglement access network, we report experimental demonstration of a secure multiparty computation protocol, the privacy-preserving secure sum problem, based on the network quantum cryptography.

    Issue evolution has become a well-established theoretical perspective in the analysis of long-term electoral behavior and partisan alignments in the U.S. after the emergence of the cultural wars. Outside the U.S., however, this perspective has been rarely used to analyze electoral behavior...... analytical validity and usefulness in the analysis of electoral behavior beyond the U.S.-case....... two party systems, fringe parties act as catalysts of issue evolution on the elite-level which is then followed by mainstream party adaption and the mass electorate realignment. Applying and refining the issue evolution perspective to a multiparty context, this paper therefore demonstrates its...

    Secure multi-party computation (MPC) is a technique well suited for privacy-preserving data mining. Even with the recent progress in two-party computation techniques such as fully homomorphic encryption, general MPC remains relevant as it has shown promising performance metrics in real...... operations such as multiplication and comparison. Secondly, the confidential processing of financial data requires the use of more complex primitives, including a secure division operation. This paper describes new protocols in the Sharemind model for secure multiplication, share conversion, equality, bit...

    Secure multi-party computation (SMC) is a research focus in international cryptographic community. At present, there is no SMC solution to the intersection problem of sets. In this paper, we first propose a SMC solution to this problem. Applying Cantor encoding method to computational geometry problems, and based on the solution to set-intersection problem, we further propose solutions to points inclusion problem and intersection problem of rectangles and further prove their privacy-preserving property with widely accepted simulation paradigm. Compared with the known solutions, these new solutions are of less computational complexity and less communication complexity, and have obvious superiority in computational and communication complexity.

    Election Studies. In both multiparty elections, the impact of information has significant consequences for party choice. In 1971, political knowledge seems to be the variable connecting class with party choice, whereas political knowledge seems to be the variable connecting issues with party choice in 2005....... The information effects are greater than the effects observed in similar analyses of the American two-party system, thus suggesting a positive relationship between the number of parties and the impact of political knowledge. Finally, the analysis supports the notion that right-leaning parties tend to fare better...

    Vincent Tabone may be unique in the history of ophthalmology. He practiced ophthalmology for 40 years in his homeland, the Republic of Malta. During that time, he became well known as a pioneer in the international effort to eradicate trachoma worldwide. At age 53, he began a long and successful political career as a member of parliament, then as a cabinet minister, and, finally, as the democratically elected president of the Republic. He was active in European diplomacy and made important contributions at the United Nations. He may be the only ophthalmologist who has made great contributions in the field of medicine and in the democratic development of his country.
