Knowledge of HIV prevention biomedical tools among African immigrants in France: the Makasi project

Background

In France, post-exposure prophylaxis (PEP) and pre-exposure prophylaxis (PrEP) have been available for several years. However, there is still no evidence on the level of knowledge of these HIV prevention tools among immigrants from sub-Saharan Africa living in precarious situations, a population particularly affected by HIV. The aim of this study is to describe the knowledge of these tools in this population and analyse the factors associated with this knowledge.

Methods

The data mobilized are from the Makasi interventional research that was conducted between 2018 and 2020 among immigrants from sub-Saharan Africa in precarious situations in the greater Paris area. Using data collected from 601 participants, we described levels of knowledge of HIV treatment effectiveness, treatment as prevention (TasP), post-exposure prophylaxis (PEP), and pre-exposure prophylaxis (PrEP), by sex with a chi2 test. We investigated factors associated with their knowledge with logistic regressions adjusted for sociodemographic characteristics, living conditions and sexual behaviors (p ≤ 0.2).

Results

The population surveyed was predominantly men (76%), from West Africa (61%) and in a precarious situation: 69% were unemployed, 74% were undocumented, 46% had no health coverage and 13% were homeless. In this population, knowledge of antiretroviral treatments for HIV prevention was heterogeneous: the effectiveness of HIV treatment was well known (84%), but only half of the respondents (46%) were aware of TasP and very few knew about PEP and PrEP: 6% and 5% respectively. Multivariable-adjusted models showed that these tools was better known by educated people, those who had a social network in France, those who have had access to the health system and those who were exposed to sexual risks.

Conclusions

While sub-Saharan African immigrants know the effectiveness of HIV treatment and use certain prevention tools such as HIV testing, they are not aware of PEP and PrEP.

Health empowerment and access to health coverage among immigrants in France: the Makasi intervention

Background

The Makasi community-based research project offered an innovative health-related empowerment intervention to immigrants from sub-Saharan Africa living in precarious situations in the greater Paris area, to reduce their social vulnerability and their exposure to HIV. Our objective is to evaluate the impact of the intervention on access to health coverage in this population.

Methods

Participants were recruited based on precariousness criteria in public places in Ile-de-France (squares, railway stations, markets, etc.) by mobile teams of social workers and health mediators. Following a stepped-wedge design, participants were randomised into two groups receiving the intervention sequentially (immediately in one group and 3 months later in the other). We evaluated the impact of the Makasi intervention on access to health coverage among 821 individuals observed at 0, 3, and 6 months, between 2018 and 2021. We implemented random-effects panel models - allowing for unobserved heterogeneity - using a Heckman selection approach to correct for attrition. Finally, we used seemingly unrelated regressions (SUR) to examine the extent to which the effect of the intervention was mediated by health-related empowerment.

Results

Participants - 77% of which were men - had been living in France for 4 years on average. 44% of them had no health coverage at the time of inclusion. Our results provided evidence for a significant impact of the Makasi intervention on participants’ access to health coverage, with an 18 percentage-point increase in the probability of accessing health coverage 6 months after having received the intervention (p < 0.01). The mediation analysis revealed that this effect operated partly through an empowerment process in terms of knowledge of social and health resources.

Conclusions

We showed that a health empowerment intervention provided by social workers and health mediators largely favours access to health rights for immigrants in precarious situations.

Key messages

• A health empowerment intervention improved access to health coverage among immigrants from sub-Saharan Africa living in precarious situations in France.

• Improvement in access to health coverage was found to be partly mediated by reinforcement of participants’ health literacy in terms of social and health resources.

Molecular characterization of African Swine fever viruses in Burkina Faso, Mali, and Senegal 1989-2016: Genetic diversity of ASFV in West Africa

African swine fever (ASF) has been endemic in sub-Saharan Africa since the 1960s. Following its introduction in Senegal, in 1957, ASF steadily progressed through West Africa, reaching Burkina Faso in 2003, and later Mali in 2016. Despite the heavy burden of disease on pig production, little information is available on the genetic diversity of Africa swine fever virus (ASFV) in Burkina Faso, Mali and Senegal. Here, we used real-time PCR ASFV to detect the ASFV genome in samples collected between 1989 and 2016, in Burkina Faso, Mali and Senegal, and conventional approaches for isolate characterization. The C-terminal end of the p72 protein gene, the full E183L gene and the central variable region (CVR) within the B602L gene in ASFV genome were sequenced and compared to publicly available sequences. ASFV genome was found in 27 samples, 19 from Burkina Faso, three from Mali and five from Senegal. The phylogenetic analyses showed that all viruses belong to genotype I, with the ASFVs from Burkina Faso and Mali grouping with genotype Ia and ASFV serogroup 4, and those from Senegal with genotype Ib and the ASFV serogroup 1. The analysis of the CVR tetrameric tandem repeat sequences (TRS) showed four TRS variants in Burkina Faso, two in Senegal and one in Mali. The three countries did not share any common TRS, and all CVRs of this study differed from previously reported CVRs in West Africa, except for Senegal. Three of the five isolates from Senegal fully matched with the CVR, p72 and p54 sequences from ASFV IC96 collected during the 1996 ASF outbreak in Ivory Coast. This study shows the spread of the same ASFV strains across countries, highlighting the importance of continuous monitoring of ASFV isolates. It also calls for an urgent need to establish a regional plan for the control and eradication of ASF in West Africa.

[Management of chronic osteomyilitis of limbs at kati teaching hospital]

OBJECTIVES

the purpose of this work was to describe the epidemiological, clinical, paraclinical and therapeutic aspect of surgical treatment of chronic osteomyilitis of limbs.

PATIENTS METHODS

it was a retrospective study over a period of 12 years, from January 2003 to December 2014. It covered all cases of chronic osteomyelitis osteonecrosis treated our service.

RESULTS

The authors report the results of the surgical treatment of a series 56 patients operated on for chronic limb osteomyelitis. The mean age was 20.7 years with extremes of 6 months and 56 years. The tibia and femur were the most affected segments. Staphylococcus aureus was the most frequently found germ, 80% of the cases. We obtained complete healing with total cure in 68% of cases and recurrence of suppuration in 32% of cases.

CONCLUSION

Chronic osteomyelitis of limbs is a frequent pathology in Africa. Staphylococcus aureus was the most frequently found germ. Surgery in a time seems a good alternative. The rate of recurrence of the suppuration remains high.

[Prevalence of the kidney disease at the emergency department of hospital Fousseyni Daou of Kayes]

INTRODUCTION

Kidney disease (KD) is defined as a set of functional, morphological and histological kidney abnormalities. It is a truly global public health problem. Its prevalence is estimated to be 50 times that of end-stage renal disease (ESRD). In Kayes, there is no data on the prevalence of kidney disease, hence the interest of this study.

OBJECTIVES

to determine the prevalence of renal disease, its main causes and the main factors of aggravation of this pathology in the emergency department at hospital Fousseyni DAOU of Kayes.

METHODOLOGY

Retrospective cross-sectional study carried out from January 1, 2014 to February 1, 2015. We included all hospitalized patients in whom a renal damage marker (elevation of plasma creatinine, urinary sediment abnormality, ultrasound, histology and significant proteinuria) has been found.

RESULTS

the prevalence of kidney disease was 9.9% (109/1099). Eighty-nine met the inclusion criteria. The study population was composed of 47 women (52.8%) and 42 men (47.2%), with a sex ratio of 0.89 in favor of women. The average age was 40.09 years with a predominance of patients in the age group [40-59]. The main reasons for consultation were hypercreatininaemia (48.3%), edematous syndrome (16.9%), low back pain (10.1%). High blood pressure (55.1%) and lower extremity edema (46.1%) were the medical history frequently found in our study. The kidney disease found was in order of growth: chronic renal failure (51%); acute renal failure (28%); proteinuria (16%), hematuria (3%), morphological abnormality of the kidneys (2%). Tubulointerstitial nephropathy represented 64% of acute renal failure with P = 0.000306. Vascular nephropathy constituted 46.7% of chronic renal failure with P = 0.000251. No cases of glomerular nephropathy were found in patients over 60 years of age.The most common causes were represented by nephrotoxic drugs injuries; infectious; high blood pressure and diabetes. The most observed aggravating factors are herbal medicine, urinary tract infections, renal hypoperfusion and unbalanced hypertension.

CONCLUSION

kidney disease is not uncommon in the emergency room at Hospital Fousseyni Daou of Kayes. The most common causes are nephrotoxic drugs, hypertension and diabetes.

[Aseptic nonunion of patella at the Centre Hospitalier Universitaire Bocar Sidy Sall de Kati about 25 cases]

OBJECTIVE

The objective of Our study was to describe the epidemiological, clinical, therapeutic and prognostic aspects of Nonunion of patella fractures.

PATIENTS METHODS

It was a retrospective study done concerning 25 patients treated fromJanuary 2005 to December 2015 in the orthopedic trauma service CHU Bocar Sidy SALL Kati.

RESULTS

We gather together 25 cases of Nonunion of patella fractures disease among 28 caseswhich was about 89.28%. Our patients were divided into 20 men and 5 women, mean age was 36 years, ranging from ages 22 to 75 years. Posttraumatic period was 6-18 months. The initial fracture was neglected in 21 cases and treated in 4 cases. Physical examination revealed lameness in 92% of cases, atrophy of the quadriceps in 56% of cases, joint stiffness, 56% and an inter-fragmentary gap in 92% of patients. The radiographic data were consistent with pseudoarthrosis in all cases. The inter-fragmentary gap was 36 mm on average. The care of our patients was based on plugging and guy-wiring in 64 % of cases and strapping pre- and peri patella in 12% of cases. A partial patellectomy was practiced in 2 cases. A VY plasty of the quadriceps was recommended in 4 cases.The patients were reviewed after a mean of 10 months (8 months- 24 months). Functional outcomes analyzed using Bostman scores were excellent in 4 cases (16%), good in 18 cases (72%) and poor in 3 cases (12%).

CONCLUSION

Nonunion of the patella is mostly due to the lack of treatment or wrong treatment leads. Treatment with plugging and guy-wiring seems the most appropriate method.

A longitudinal communication approach in advanced lung cancer: A qualitative study of patients', relatives' and staff's perspectives

Communication and the care of patients with advanced cancer are a dynamic, interactive and challenging process, often characterised in every day practice by discontinuity and lack of coordination. The objective of this study was to explore the patients' and family-caregivers' needs and preferences regarding communication, quality of life and care over the trajectory of disease. The second aim was to assess health professionals' views on a longitudinally structured, forward-thinking communication approach based on defined milestones. A qualitative approach was chosen incorporating semi-structured interviews with nine patients with metastatic lung cancer and nine relatives, and focus groups with 15 healthcare providers from different professions involved in the care of these patients. Patients and relatives described a situation of shock and coping deficits with moments of insufficient communication and lack of continuity in care. Healthcare providers reported the strong need for improvement in communication within the team and between patients and professionals and welcomed the implementation of a longitudinal communication approach. Requirements for the implementation of a longitudinal communication approach include specific communication training with focus on the process that patients and relatives are involved in. Team-building measures and the necessary flexibility to respect individuality in life should be incorporated.

Reflection of illness and strategies for handling advanced lung cancer - a qualitative analysis in patients and their relatives

Background

Lung cancer patients are often diagnosed in an advanced stage of disease. In a situation of palliative treatment, both patients and their relatives experience existential burden. Evidence suggests that multi-professional teams should deal with them as dyads. However, little is known about differences in their individual situation. The purpose of this study is to explore and compare reflections that arise out of the context of diagnosis and to compare how patients and their relatives try to handle advanced lung cancer.

Methods

Data was collected by qualitative interviews. A total of 18 participants, 9 patients diagnosed with advanced lung cancer (ICD- 10 C-34, stage IV) starting or receiving palliative treatment and 9 relatives were interviewed. Data was interpreted using qualitative content analysis.

Results

Reflection aspects were “thoughts about the cause”, “meaning of belief” and “experience of inequity”. Patients often experienced the diagnosis as inequity and were more receptive for believing in treatment success. The main strategies found were “repression”, “positive attitude”, “strong focus on the present” and “adjustment of life terms”. Patient and relative dyads used the same strategies, but with different emphasis. That life time is limited was more frequently realized by relatives than by patients.

Conclusion

While strategies used by relatives are similar to those of patients’, they are less reflective and more pragmatic in terms of handling daily life and organizing care. The interviewed patients were mostly not able to takeover these tasks. To strong was their belief in treatment success, their repression of the future and the focus on the present. This implicates, that in terms of end-of-life care, relatives are important to reach patients who are often not receptive to this topic.

Individual difficulties and resources - a qualitative analysis in patients with advanced lung cancer and their relatives

PURPOSE

Lung cancer is a disease with a high percentage of patients diagnosed in an advanced stage. In a situation of palliative treatment, both patients and their relatives experience diverse types of distress and burden. Little research has been done to identify the individual difficulties and resources for patients with advanced lung cancer and their relatives. Especially, standardized questionnaire-based exploration may not assess the specific distressing issues that pertain to each individual on a personal level. The purpose of this qualitative study is to explore and compare individual difficulties and resources for lung cancer patients and their relatives within the palliative care context.

METHODS

Data were collected by qualitative interviews. A total of 18 participants, nine patients diagnosed with advanced lung cancer (International Classification of Diseases, tenth edition, diagnosis C-34, stage IV) starting or receiving palliative treatment and nine relatives, were interviewed. Data were interpreted through qualitative content analysis.

RESULTS

We identified four main categories of difficulties: communication and conflicts, home and everyday life, thinking about cancer, and treatment trajectory. In general, difficulties were related to interpersonal relationships as well as to impact of chemotherapy. Family, professional caregivers, and social life were significant resources and offered support to both patients and relatives.

CONCLUSION

Results suggest that patient and relative education could reduce difficulties in several areas. Patients seem to struggle with the fear of not having any perspective in therapy. Relatives seem to experience helplessness regarding their partner's deterioration and have to handle their own life and the care work simultaneously. The most important resource for both patients and relatives is their family. In addition, professional lung cancer nurses support relatives in an emotional and organizational way. Intense supportive care for relatives should be standardized.

Antibacterial properties studies of trunk barks of Terminalia ivorensis, a commercial and medicinal species on some methicillin-resistant Staphylococci species strains

BACKGROUND

Methicillin-resistant Staphylococcus aureus, Staphylococcus epidermidis and coagulase-negative Staphylococcus infections are a worldwide concern. Terminalia ivorensis, of Combretaceae family plant, is widely used traditional medicinal in Côte d'Ivoire to treat dermal diseases (affection in which Staphylococci are implied) including local inflammation and also to treat voice-loss.

OBJECTIVES

This study focused to investigate the effect in vitro of the extracts of trunk barks of Terminalia ivorensis on some methicillin/oxacillin-resistant strains of Staphylococcus aureus, S. epidermidis, coagulase-negative S. and reference strain of S. aureus ATCC 25923.

METHODS

Antibacterial activity of aqueous, 70% ethanolic 70% and aqueous residue extracts was assessed using agar disc-diffusion method and liquid medium microdilution method in 96 multi-well micro-titer plates. This method led us to determine minimum inhibition concentration (M.I.C.) and minimum bactericidal concentration (M.B.C.). The presence of chemical groups major was detected qualitatively.

RESULTS

Aqueous and 70% ethanolic 70% extracts showed significant activity against all the bacteria except aqueous residue when compared with the standard antibiotic oxacillin (5 µg/ml). M.I.C. for aqueous and 70% ethanolic 70% extracts ranged from 0,83-16,67 mg/ml and 0,156-13,33 mg/ml respectively. Viable cell determination revealed the bactericidal nature of the two barks extracts. The 70% ethanolic 70% extract exhibited the highest activity according to the M.B.C. values. The phytochemical analysis indicates the presence of tannins, saponins, flavonoids, terpen/sterols, coumarins, polyphenols and traces of alkaloid.

CONCLUSION

The in-vitro antibacterial efficacy shown by the barks of this plant and his lushness in chimical compounds, would justify use of this one in the traditional treatment of some diseases of microbial origin. These compounds could be suggested to provide alternative solution to the development of new therapeutic agents.

[Surgical options in the treatment of noma]

In the acute phase of noma, the role of surgery is minor and the treatment consists in the realisation of local or regional flaps and sometimes the management of haemorragia. For reasons social and economic reconstruction of the loss of substance should be conducted on site. The treatment consists of surgical excision of fibrous tissue, the removal of the ankylosis and the closure of the PDS by local flaps, or free pediculated. Because of the extreme variety of loss of substance (PDS) and the multiple surgical options, a systematic and eventually, the standardization of the surgical approach in the treatment of sequelae of noma is essential.
