Thesis Abstract: "Life experiences associated with cancer: a study of women living with breast cancer treated at at the Centre Hospitalo-Universitaire de Kamenge" Breast cancer represents a major global public health challenge and is the most frequently diagnosed cancer among women. In Burundi, breast cancer diagnoses are often delayed, and access to specialized care remains limited. Beyond the medical aspects, the disease profoundly affects the identity, body image, and femininity of the women involved, as well as their family and social relationships. This study examines the life experiences of women with breast cancer receiving care at at the Centre Hospitalo-Universitaire de Kamenge. It aims to understand their reactions to the diagnosis, analyze their psychological experiences throughout the course of treatment, and study their coping strategies in the face of the disease. The study employs a qualitative approach based on semi-structured interviews with four female volunteers. Thematic analysis revealed key findings, notably that receiving the diagnosis is a deeply distressing event characterized by shock, fear of death, a state of stunned disbelief, and anxiety about the future. Treatments also bring about physical changes that affect self-image, femininity, and relationships. To cope, patients draw upon family support, spirituality, a gradual acceptance of the illness, and trust in healthcare professionals. Thus, this study highlights the importance of a holistic approach to breast cancer that integrates psychological, social, and existential dimensions, and recommends strengthening psychosocial support within oncology care services in Burundi.
La problématique de la limitation des mandats présidentiels en Afrique des grands lacs : le cas du Burundi de 2015-2024

Presidential term limits are a fundamental principle of democracy, aimed at preventing the concentration of power in the hands of a single person or political party and ensuring the rotation of leaders. However, in the Great Lakes region, this principle is often marred by its Achilles' heel, as demonstrated by the case of Burundi in 2015, when President Pierre Nkurunziza, aided by a faction of the CNDD-FDD, attempted to run for a third term. The process of presidential term limits is rooted in the rule of law. However, if the rule of force prevails over the rule of law, weak institutions result. Therefore, term limits require strong leaders to build strong institutions. While the rule governing term limits existed in the constitution and the Arusha Peace and Reconciliation Agreement for Burundi, it lacked real force. The prevailing logic was neo-patrimonialism and monocentric presidentialism, which constituted the failure of presidential term limits. This was because the Head of State, aided by his party, treated the state as his private property. To understand this problem, sociohistorical theories of politics and constitutional theories were of great importance to us. Methodologically, we opted for a hermeneutic approach (reading works, statements, etc.), as well as a qualitative approach (a semi-structured survey conducted with representatives of political parties, civil society, and members of parliament). All these methods played a role in the development of this thesis. Pierre Nkurunziza's third term, supported by the CNDD-FDD party, was beneficial to those whose interests it protected, including himself, given its success. Despite its success, the opposition, civil society organizations, and some powers, including the international community, have condemned the CNDD-FDD for violating the law. This use of force has triggered a crisis that has led to murders and the exile of the country's children. This disregard for term limits has been facilitated by the vulnerability of democracy. The law has yielded to the interests of those in power. After analyzing various data and information from different informants, it is clear that Burundi has been characterized by conflict and political violence since its independence. This reinforces neo-patrimonialism and a one-sided presidential system, leading the ruling parties to view the state as a source of revenue for the ruling party.

Acute malnutrition remains a major public health problem in developing countries, particularly among children aged 6 to 59 months. In the Uvira Health Zone, the factors associated with acute malnutrition remain insufficiently documented. This study aimed to identify these factors through a descriptive cross-sectional study with an analytical component conducted from October 2025 to April 2026 among 423 children selected using multistage random sampling. Data were collected using a structured questionnaire administered through KoboCollect and analyzed using Stata version 15. A bivariate analysis was performed at a 5% significance level (α = 0.05), and variables with a p-value < 0.20 were included in the multivariable model. Multivariable logistic regression was then used to estimate adjusted odds ratios (AORs) with 95% confidence intervals (95% CI), considering variables with p < 0.05 as statistically significant. The multivariable analysis revealed that several protective factors were significantly associated with a reduced risk of acute malnutrition. These included maternal education level, the child’s age, exclusive breastfeeding, the use of an improved water source, livestock ownership, the presence of a household vegetable garden, and good maternal nutritional knowledge (corresponding AORs: 0.31 and 0.16; 0.27 and 0.19; 0.29; 0.26; 0.42; 0.13; and 0.30, respectively). The findings highlight the multifactorial nature of acute malnutrition in the Uvira Health Zone and underscore the need to integrate educational, nutritional, socioeconomic, and environmental factors into prevention strategies through a comprehensive approach focused on improving living conditions and strengthening mothers’ capacities.
La collaboration dans le pluralisme thérapeutique au Burundi : étude menée dans les communes Mukaza et Ntahangwa de la province de Bujumbura

This research work focuses on collaboration within therapeutic pluralism in the communes of Mukaza and Ntahangwa in Bujumbura Province. It analyzes the interactions between biomedical practitioners, traditional healers, and religious leaders, as well as their effects on patients’ therapeutic pathways and access to healthcare services. The study is based on the observation that the Burundian healthcare system is characterized by the coexistence of multiple therapeutic systems operating simultaneously. The main objective is to examine the dynamics of collaboration, competition, and tension among these actors in order to understand their socio-anthropological implications for healthcare delivery. Data were collected through a qualitative approach, including interviews, life histories, and documentary analysis involving the various stakeholders. The findings show that collaboration among therapeutic actors mainly exists in informal forms, particularly through patient referrals and occasional advice between practitioners. However, this collaboration remains limited by several constraints, including mutual mistrust, cultural and religious differences, the absence of a clear legal and institutional framework, andconflicts over legitimacy between healthcare systems. Patients play a central role in connecting these systems by constructing multiple and circular therapeutic itineraries. The study concludes that therapeutic pluralism is both a resource for the healthcare system. It promotes diversified access to care but also leads to fragmented and sometimes inefficient therapeutic pathways due to the lack of coordination. Therefore, formalizing collaboration, strengthening health education, and valuing local knowledge appear as key strategies to improve comprehensive patient care.

Ground instability is one of the most spectacular and frequent geodynamic phenomena worldwide. Its occurrence causes significant morphological changes to the terrain and affects exposed infrastructure, human activities, and ecosystems. These phenomena result from several factors that contribute to their occurrence. The Gikoma River watershed is located partly in the Imbo plain and partly in the Mirwa region, in the province of Bujumbura. Due to its natural characteristics, this watershed is particularly prone to the development of numerous types of ground instability. These are influenced by several factors, including lithology, pedology, rock fracturing, land use, the hydrographic network, slope and exposure of the slopes. The highly rugged topography, torrential rains and reduced vegetation cover are the main factors contributing to the instability of the terrain in this watershed. During the rainy season, the clay soils become saturated with water and more susceptible to landslides. During the rainy season, clay soils become saturated with water and more prone to slipping. An inventory of ground instability was carried out by analysing aerial images and photographs and based on in situ observations. A total of 78 mass movements were identified: rockfalls (37.20%), translational slides (26.92%), rotational slides (7.69%), complex movements (6.41%), collapses (8.97%), fissures (3.85%), water erosion (3.85%), mudflows (2.56%), scouring (1.28%) and subsidence (1.28%). Slope and torrential rainfall are the main factors playing a major role in the process of land instability in the study area. A diachronic study of land use based on satellite images from 2002, 2014 and 2024 reveals that changes in land use play a major role in triggering ground movements within the Gikoma River watershed. The recent intensification of these phenomena is thought to be mainly linked to the gradual deterioration of the environment in the catchment area. After subjecting the factors responsible for ground instability to hierarchical multi-criteria analysis using an AHP method, the susceptibility map produced showed the stable areas (Buhayira, Giterama and Tenga) and unstable areas (Kindobwe, Kagoma, Kwigere, Masake and along the watercourses: Kigezi, Nkuri and Karunga) in our study area.
