The CFA Franc: French monetary imperialism in Africa

Ndongo Samba Sylla argues that the CFA franc - officially created on 26 December 1945 by a decree of General de Gaulle - used across much of Africa today is a colonial relic. For those hoping to export competitive products, obtain affordable credit, work for the integration of continental trade, or fight for an Africa free from imperialist control, the CFA franc is an anachronism demanding orderly and methodical eliminatio

Derisking developmentalism: A tale of green hydrogen

In the global race to scale up green hydrogen, a renewed appetite for the visible hand of the state once again promises to expand developmental space for low- and middle-income countries. On the African continent, several countries have announced green industrialization ambitions that rely on mobilizing, through various ‘derisking’ schemes, private (institutional) capital looking for investible opportunities. To examine the transformative potential of this new derisking developmentalism, this article extends the critical macrofinance lens to include Thandika Mkandawire's theorization of post-independence African developmental states. Using Namibia as an illustration, it argues that an assumption of ‘divine coincidence’ creates the ideological space for the state to forge derisking blocs but structurally weakens its ability to discipline private capital into pursuing green industrialization. As (foreign) capital dominates the state‒capital relationship in derisking developmentalism, the new green rules written by powerful investors and global North governments threaten to transform global South countries into consumers of green hydrogen technology and generators of yield for portfolio investors, thus reinforcing the structural drivers of their ongoing external debt vulnerabilities. Instead, countries should experiment with green public ownership and partnerships that discipline local green industries. Such strategies require replacing the Wall Street Consensus with a supportive global macrofinancial framework the authors call ‘Green Bandung Woods’

Fièvre bilieuse hémoglobinurique (FBH) de révélation tardive: à propos d’un cas au CHU de Dakar

La fièvre bilieuse hémoglobinurique (FBH) est une forme grave du paludisme; caractérisée par la survenue d'une hémolyse intravasculaire aiguë se traduisant par une anémie hémolytique, une insuffisance rénale aiguë et une hypovolémie. Son diagnostic repose essentiellement sur la clinique notamment la couleur  des urines d'aspect rouge porto. Nous rapportons un cas de fièvre bilieuse hémoglobinurique chez un jeune garçon de 10 ans originaire et vivant dans une zone d'endémie palustre, colligé dans un CHU de Dakar  (Sénégal). V.G est un garçon de 10 ans qui était hospitalisé pendant 2 jours au service des urgences dans un centre de santé de proximité pour une fièvre associée à des vomissements qui évoluaient depuis 3 jours. Le test de diagnostic rapide (TDR) au paludisme était positif à la présence d'antigènes de   Plasmodium falciparum dans le sang. Un traitement à base de quinine injectable (25 mg/kg/j), a été   entrepris pendant 03 jours. Au quatrième jour, sont apparues une hémolyse intravasculaire aiguë et une  hémoglobinurie avec une insuffisance rénale aiguë anurique. La goutte épaisse était revenue négative et le traitement par la quinine injectable arrêté. Le relais a été fait avec les dérivés de l'artémisinine. Trois  (03) séances d'hémodialyse ont été réalisées. L'évolution était favorable, par la reprise de la diurèse et la normalisation de la fonction rénale. La FBH existe encore dans notre pratique quotidienne. Il faut y penser devant l'apparition brutale d'une hémolyse avec insuffisance rénale aiguë et urines rouges porto au cours du traitement d'un paludisme.Key words: Paludisme grave, hémoglobinurie, quinin

A short-term assessment of nascent HIV-1 transmission clusters among newly diagnosed individuals using envelope sequence-based phylogenetic analyses

The identification of transmission clusters (TCs) of HIV-1 using phylogenetic analyses can provide insights into viral transmission network and help improve prevention strategies. We compared the use of partial HIV-1 envelope fragment of 1,070 bp with its loop 3 (108 bp) to determine its utility in inferring HIV-1 transmission clustering. Serum samples of recently (n = 106) and chronically (n = 156) HIV-1-infected patients with status confirmed were sequenced. HIV-1 envelope nucleotide-based phylogenetic analyses were used to infer HIV-1 TCs. Those were constructed using ClusterPickerGUI_1.2.3 considering a pairwise genetic distance of £10% threshold. Logistic regression analyses were used to examine the relationship between the demographic factors that were likely associated with HIV-1 clustering. Ninety-eight distinct consensus envelope sequences were subjected to phylogenetic analyses. Using a partial envelope fragment sequence, 42 sequences were grouped into 15 distinct small TCs while the V3 loop reproduces 10 clusters. The agreement between the partial envelope and the V3 loop fragments was significantly moderate with a Cohen’s kappa (j) coefficient of 0.59, p < .00001. The mean age (<38.8 years) and HIV-1 B subtype are two factors identified that were significantly associated with HIV-1 transmission clustering in the cohort, odds ratio (OR) = 0.25, 95% confidence interval (CI, 0.04–0.66), p = .002 and OR: 0.17, 95% CI (0.10–0.61), p = .011, respectively. The present study confirms that a partial fragment of the HIV-1 envelope sequence is a better predictor of transmission clustering. However, the loop 3 segment may be useful in screening purposes and may be more amenable to integration in surveillance programs

HIV-1 envelope sequence-based diversity measures for identifying recent infections

Identifying recent HIV-1 infections is crucial for monitoring HIV-1 incidence and optimizing public health prevention efforts. To identify recent HIV-1 infections, we evaluated and compared the performance of 4 sequence-based diversity measures including percent diversity, percent complexity, Shannon entropy and number of haplotypes targeting 13 genetic segments within the env gene of HIV-1. A total of 597 diagnostic samples obtained in 2013 and 2015 from recently and chronically HIV-1 infected individuals were selected. From the selected samples, 249 (134 from recent versus 115 from chronic infections) env coding regions, including V1-C5 of gp120 and the gp41 ectodomain of HIV-1, were successfully amplified and sequenced by next generation sequencing (NGS) using the Illumina MiSeq platform. The ability of the four sequence-based diversity measures to correctly identify recent HIV infections was evaluated using the frequency distribution curves, median and interquartile range and area under the curve (AUC) of the receiver operating characteristic (ROC). Comparing the median and interquartile range and evaluating the frequency distribution curves associated with the 4 sequence-based diversity measures, we observed that the percent diversity, number of haplotypes and Shannon entropy demonstrated significant potential to discriminate recent from chronic infections (p<0.0001). Using the AUC of ROC analysis, only the Shannon entropy measure within three HIV-1 env segments could accurately identify recent infections at a satisfactory level. The env segments were gp120 C2_1 (AUC = 0.806), gp120 C2_3 (AUC = 0.805) and gp120 V3 (AUC = 0.812). Our results clearly indicate that the Shannon entropy measure represents a useful tool for predicting HIV-1 infection recency

Factors Affecting the Statural Growth Retardation in Children using Steroids in Idiopathic Nephrotic Syndrome

Background and Aim: Idiopathic nephrotic syndrome or nephrosis causes massive protein leakage in the urine. Its treatment requires steroids (prednisone, methylprednisolone), often for a prolonged period, notably in case of steroid-dependence or steroid-resistance. In children, long-term use of steroids can lead to several side effects such as statural growth retardation/ stunting. This study evaluated the frequency of stunting in idiopathic nephrotic syndrome in children on steroids and identified the associated factors.     &#x0D; Material and Methods: This was a retrospective, descriptive cohort study carried out in children aged 0 to 16 years treated at the paediatric nephrology unit of Aristide Le Dantec Hospital in Dakar, between 1 December 2017 and 31 May 2020. All records of nephrotic children treated in outpatient or inpatient setting were included. These children had to be on corticosteroid therapy for at least 30 months and have a height taken regularly during follow-up consultations.&#x0D; Results: Of 259 children followed for idiopathic nephrotic syndrome, 93 were included in the study. The median age was 96.5 months and the sex ratio was 1.9. The mean height of the children at the beginning of the follow-up was -0.26 DS, at the end it was -0.88 DS. At the beginning of the follow-up, 8 children had already stunting. At 12 months follow-up, 72 children (77.4%) had a decrease in z-score; and at 30 months, there were 7 more children (84.9%) who had a decrease in z-score. Methylprednisolone boluses were given to 17 children (18.3%). Calcium supplementation was done in 91 children (97.8%). Vitamin D supplementation was given to 91 children (97.8%). The mean number of relapses was 1.8. Factors associated with stunting were number of relapses ≤3 (p=0.03), duration of corticosteroid therapy &gt;6 months (p&lt;0.0001) and cumulative doses of prednisone &gt;100 mg/kg (p=0.04).&#x0D; Conclusion: In prolonged nephrotic syndrome in children, corticosteroids can cause stunting

Senegal: Presidential elections 2019 - The shining example of democratic transition immersed in muddy power-politics

Whereas Senegal has long been sold as a showcase of democracy in Africa, including peaceful political alternance, things apparently changed fundamentally with the Senegalese presidentials of 2019 that brought new configurations. One of the major issues was political transhumance that has been elevated to the rank of religion in defiance of morality. It threatened political stability and peace. In response, social networks of predominantly young activists, created in 2011 in the aftermath of the Arab Spring focused on grass-roots advocacy with the electorate on good governance and democracy. They proposed a break with a political system that they consider as neo-colonialist. Moreover, Senegal’s justice is frequently accused to be biased, and the servility of the Constitutional Council which is in the first place an electoral court has often been denounced

Introduction: Symposium on the 2022 Dakar Declaration

The second edition of the Conference on Economic and Monetary Sovereignty of Africa was held in Dakar, Senegal, on October 25–28, 2022. Participants from around the world debated the theme “Facing the Socio-Ecological Crisis: Delinking and the Question of Global Reparations.” The event was designed as a follow-up on discussions begun during the first edition (held in Tunis in 2019; see Ben Gadha et al. 2021), as well as an opportunity to reflect on recent developments.&nbsp; The Dakar Declaration is one of the main byproducts of four days of intense, fruitful, and comradely debates on the triptych of delinking, socio-ecological resilience, and reparations. It is an internationalist manifesto and a global action plan
