Abstract Background In Africa, the relationship between childhood nutritional status and malaria remains complex and difficult to interpret. Understanding it is important in the improvement of malaria control strategies. This study aimed to assess the influence of nutritional status on the occurrence of multiple malaria episodes in children aged 6 to 59 months between 2013 and 2017 living in the village of Dangassa, Mali. Methods A community-based longitudinal study was conducted using cross-sectional surveys (CSSs) at the beginning (June) and end (November) of the malaria transmission season associated with passive case detection (PCD) at the Dangassa Community Health Centre. Children with asymptomatic malaria infection during cross-sectional surveys were selected and their malaria episodes followed by PCD. Malaria indicators in person-months were estimated using an ordinal-logistic model repeated on subjects during follow-up periods. Results The incidence rate (IR) during the period of high transmission (June to October), for 1 episode and for 2 + episodes peaked in 2013 with 65 children (IR = 95.73 per 1000 person-months) and 24 cases (IR = 35.35 per 1000 person-months), respectively. As expected, the risk of multiple episodes occurring during the period of high transmission was 3.23 compared to the period of low transmission after adjusting for other model parameters (95% CI [2.45–4.26], p = 0.000). Children with anaemia were at high risk of having multiple episodes (OR = 1.6, 95% CI [1.12–2.30], p = 0.011). However, the risk of having 2 + episodes for anemic children was higher during the period of low transmission (RR = 1.67, 95% CI [1.15–2.42], p = 0.007) compared to the period of high transmission (RR = 1.58, 95% CI [1.09–2.29], p = 0.016). The trend indicated that anemic and underweight children were significantly associated with multiple malaria episodes during the period of low transmission (p

Background: The sero-epidemiological characteristics of SARS-CoV-2 infections in Mali are not yet well understood. This study assessed SARS-CoV-2 antibody seroprevalence and factors associated with antibody responses in the general population of Bamako, the capital city and epicenter of COVID-19, to assess the magnitude of the pandemic and contribute to control strategy improvements in Mali., Methods: A cross-sectional survey was conducted in September 2022 to collect sociodemographic information, clinical characteristics, comorbid factors, and blood samples. ELISA was performed to determine anti-Spike (anti-S) and anti-RBD antibody levels. A total of 3601 participants were enrolled in REDCap. R-Studio was used for the statistical analysis. The chi-squared (χ 2 ) test was used to compare the proportions across different groups. Logistic regression models were used to elucidate factors associated with antibody responses., Result: The sex ratio for female-to-male was 3.6:1. The most representative groups were the 20-29-year-olds (28.9%, n = 1043) and the 30-39-year-olds (26.9%, n = 967). The COVID-19 vaccine coverage among the participants was 35.8%, with vaccines from Covishield AstraZeneca (13.4%), Johnson & Johnson (16.7%), Sinovac (3.9%), and BioNTech Pfizer (1.8%). Overall, S protein and RBD antibody seroprevalences were remarkably high in the study population (98% and 97%, respectively). Factors such as youth (1-9 years old) and male sex were associated with lower SARS-CoV-2 antibody responses, whereas COVID-19 vaccinations were associated with increased antibody responses., Conclusion: This serosurvey demonstrated the high seroprevalence of SARS-CoV-2 antibodies and highlighted the factors influencing antibody responses, while clearly underlining an underestimation of the pandemic in Mali., (© 2024 The Author(s).

In the title salt, (C 8 H 20 N) 8 [Mo 10 O 34 ], the [Mo 10 O 34 ] 8- polyanion is located about an inversion centre and can be considered as a β -type octa-molybdate anion to which two additional MoO 4 tetra-hedra are linked via common corners. The [Mo 10 O 34 ] 8- polyanions are packed in rows extending parallel to [001] and are connected to the di-butyl-ammonium counter-cations through N-H⋯O hydrogen-bonding inter-actions., (© Gueye et al. 2024.)

We report an unusual observation of a child aged 07, who consulted us for a chronic odynophagia rebellious to multiple treatments. It dates back to one year followed by pediatrics under antibiotic therapy and anti-inflammatory in whom the examination found hypertrophy noninflammatory obstructive tonsillar. The last episode would go back a month. The rest of the general exam was unremarkable. An indication for tonsillectomy was made and was performed. We fortuitously find a large fishbone skewered in his right tonsil. The postoperative consequences were simple. With a follow-up of 12 months, the patient is doing well., (Le comité de rédaction se réserve le droit de renvoyer aux auteurs avant toute soumission à l'avis des lecteurs les manuscrits qui ne seraient pas conformes à ces modalités de présentation.

The title salt, C 14 H 16 N + ·C 6 H 7 AsNO 3 - ·H 2 O or [(C 6 H 5 CH 2 ) 2 NH 2 ][H 2 NC 6 H 4 As(OH)O 2 ]·H 2 O, ( I ), was synthesized by mixing an aqueous solution of (4-amino-phenyl)-arsonic acid with an ethano-lic solution of di-benzyl-amine at room temperature. Compound I crystallizes in the monoclinic P 2 1 /c space group. The three components forming I are linked via N-H⋯O and O-H⋯O inter-molecular hydrogen bonds, resulting in the propagation of an infinite zigzag chain. Additional weak inter-actions between neighbouring chains, such as π-π and N-H⋯O contacts, involving phenyl rings, -NH 2 and -As(OH)O 3 functions, and H 2 O, respectively, lead to a three-dimensional network., (© Traoré et al. 2023.)

Introduction: Bee sting venom is generally well tolerated. However, some rare cases of massive stings can lead to anaphylactic shock and even renal failure. This observation is the illustration of a case of acute kidney injury secondary to bee stings in a 64-year-old black african subject., Case Presentation: A 64-year-old man without a known medical history was referred to the emergency department of the Fousseyni Daou hospital in Kayes (Mali) for disturbed consciousness 4 hours after massive stings from a bee swarm. Renal failure with serum creatinine level at 752,2 µmol/L was documented on day 3 in a context of total anuria. The patient was transferred to a nephrology unit and biology confirmed renal failure associated with intravascular haemolysis and rhabdomyolysis. The kidneys were of normal size and well differentiated. The diagnosis of severe acute kidney injury due to massive envenomation induced by bee venom was evoked. The evolution was favourable, with normalization of renal function at D26 after 5 sessions of haemodialysis in parallel with transfusions of packed red blood cells., Conclusion: A massive bee attack should be considered a medical emergency because of the organic damage it can inflict. The renal prognosis depends on the number of stings, and especially on the delay and the quality of the treatment. Early initiation of dialysis treatment reduces mortality.
