Cervical cancer (CC) remains a real public health problem in low- and middle-income countries, where technical resources and competent personnel are insufficient. Persistent cervix infection by high-risk human papillomavirus (Hr-HPV) is the main cause of CC development. In the current study, we examined the distribution of Hr-HPV in the general healthy Malian population using cervicovaginal self- sampling.

Introduction: Neurological disorders (ND) have a high incidence in sub-Saharan Africa (SSA). In this region, systemic challenges of conventional medicine (CM) and cultural beliefs have contributed to a large utilization of traditional medicine (TM). Yet, data on TM and those who use it in the treatment of ND in SSA are scarce.

Article Synopsis
  • Refrigerated storage slows down the metabolism of donated red blood cells (RBCs), but they still age and change in structure during storage, which impacts transfusion effectiveness.
  • A specific type of aged RBC, called storage-induced microerythrocytes (SMEs), shows significant metabolic and protein changes that lead to their clearance from the bloodstream after a transfusion.
  • The study found that SMEs have reduced energy and antioxidant levels, irreversible protein damage, and decreased ability to deform, which makes them more prone to being removed from circulation compared to younger RBCs.

In children with sickle cell disease (SCD), splenectomy is immediately beneficial for acute sequestration crises and hypersplenism (ASSC/HyS) but portends a long-term risk of asplenia-related complications. We retrieved peripheral and splenic red blood cells (RBCs) from 17 SCD children/teenagers undergoing partial splenectomy for ASSC/HyS, 12 adult subjects without RBC-related disease undergoing splenectomy (controls), five human spleens perfused ex vivo with Hb- and Hb-RBC, and quantified abnormal RBC by microscopy, spleen-mimetic RBC filtration, and adhesion assays. Spleens were analyzed by immunohistochemistry and transmission electron microscopy (TEM).

Persistence of malaria parasites in asymptomatic hosts is crucial in areas of seasonally-interrupted transmission, where P. falciparum bridges wet seasons months apart. During the dry season, infected erythrocytes exhibit extended circulation with reduced cytoadherence, increasing the risk of splenic clearance of infected cells and hindering parasitaemia increase.

Purpose Of Review: The human spleen clears the blood from circulating microorganisms and red blood cells (RBCs) displaying alterations. This review analyzes how generic mechanisms by which the spleen senses RBC, such pitting, trapping and erythrophagocytosis, impact the pathogenesis of two major spleen-related diseases, malaria and sickle cell disease (SCD).

Recent Findings: Scintigraphy, functional histology, comparison of circulating and splenic RBC, ex-vivo perfusion of human spleens and in-silico modeling enable relevant exploration of how the spleen retains and processes RBC in health and disease.

Background: Our recent studies have shown headache disorders to be very common in the central and western sub-Saharan countries of Benin and Cameroon. Here we report headache in nearby Mali, a strife-torn country that differs topographically, culturally, politically and economically. The purposes were to estimate headache-attributed burden and need for headache care.

Introduction: Long-term exposure to high-risk human papillomavirus (Hr-HPV) is a well-known necessary condition for development of cervical cancer. The aim of this study is to screen for Hr-HPV using vaginal self-sampling, which is a more effective approach to improve women's adherence and increase screening rates.

Methods: This pilot study included a total of 100 Women living with HIV (WLWHIV), recruited from the Center for Listening, Care, Animation, and Counseling of People Living with HIV in Bamako.

Article Synopsis
  • Splenomegaly, or spleen enlargement, is commonly found in patients with malarial anemia caused by Plasmodium falciparum or P. vivax, but the reasons for this connection are not fully understood.
  • A study in Papua, Indonesia measured red blood cell (RBC) concentrations in the spleens of 37 patients, discovering that spleen size correlated positively with the amount of red-pulp and negatively with white-pulp, indicating a relationship between spleen composition and size.
  • The research revealed that retained RBCs, primarily uninfected, accounted for significant blood loss in P. falciparum infections, and this retention correlated negatively with hemoglobin levels and circulating RBC counts, highlighting the impact

Background: Epilepsy is a significant public health concern with psychosocial impacts, including fear, stigma, and misconceptions. These factors contribute to human rights violations and discrimination. The objective of this study was to describe the sociocultural representation of epilepsy in Mali.

Article Synopsis
  • Scientists found that malaria parasites, like Plasmodium falciparum, make red blood cells stiff so they can be removed by the spleen.
  • * They tested over 13,000 compounds and found 82 that could help stop malaria from spreading.
  • * Two drugs, NITD609 and TD-6450, were shown to be safe and effective in lab tests, and they might soon be tested in people.

The spleen clears altered red blood cells (RBCs) from circulation, contributing to the balance between RBC formation (erythropoiesis) and removal. The splenic RBC retention and elimination occur predominantly in open circulation where RBCs flow through macrophages and inter-endothelial slits (IESs). The mechanisms underlying and interconnecting these processes significantly impact clinical outcomes.

Article Synopsis
  • The MTHFR gene is important for processing folates and homocysteine, which can impact gene expression and potentially lead to breast cancer development; mutations in this gene may affect levels of certain compounds involved in protein synthesis and methylation.* -
  • A study was conducted using the PCR-RFLP technique on 127 breast cancer patients and 160 healthy controls in Mali to analyze the genotypic profiles related to MTHFR mutations, revealing similar distributions of genotypes in both groups.* -
  • The research found no significant association between MTHFR gene polymorphisms and breast cancer risk among the Malian population, indicating that these genetic variations did not influence the likelihood of developing the disease.*

The Duke-Davidoff-Masson syndrome (DDMS) is a rare neurological condition with unknown prevalence, globally. To date, <100 cases have been reported worldwide. We report the case of an 18-year-old patient admitted for status epilepticus seizure, and who presented a right hemiparesis, body asymmetry, joints ankylosis, and mental retardation.

Article Synopsis
  • The study aimed to evaluate how genetic variations (polymorphisms) in CYP2B6 and CYP3A4 affect the health responses of HIV-positive patients, focusing on their viral load and immune system functioning.
  • A total of 153 patients were involved, and assessments were made on their viral loads and CD4 T cell counts at the start and after six months, utilizing TaqMan genotyping assays to identify genetic markers.
  • Results indicated that certain genetic variations, particularly in CYP2B6, correlate with viral load suppression and increases in CD4 cell counts, suggesting these genetic markers could help predict treatment outcomes in HIV patients.

Introduction: Cervical cancer screening coverage rate is <5% in Sub-Saharan Africa and <2% in French- speaking African countries. In 2016, we implemented strategies to improve cervical cancer screening in Bamako, the "Weekend70 program". The present study objectives are to determine the effect of this program on women's participation in cervical cancer screening in Bamako, and to estimate the cervical cancer screening coverage rate in Bamako.

To ensure the transport of nutrients necessary for their survival, Plasmodium falciparum parasites increase erythrocyte permeability to diverse solutes. These new permeation pathways (NPPs) have been extensively characterized in the pathogenic asexual parasite stages, however the existence of NPPs has never been investigated in gametocytes, the sexual stages responsible for transmission to mosquitoes. Here, we show that NPPs are still active in erythrocytes infected with immature gametocytes and that this activity declines along gametocyte maturation.
