Evaluating lactate prognostic value in children suspected of acetaminophen-induced liver failure in LiberiaHaidar, MK; Morton, N; Roederer, T; Mayronne, S; Bawo, L; Kerkula, J; Porten, K; Baud, FJ (Springer Nature, 2020-01-29)BACKGROUND: The prognostic significance of hyperlactatemia in young children with liver injury suspected to be attributed to repeated supratherapeutic doses of acetaminophen remain understudied. METHODS: We conducted a retrospective medical chart review including children aged <5 years admitted with hepatocellular injury. The study was conducted in Bardnesville Junction Hospital operated by Médecins Sans Frontières in Monrovia, Liberia. RESULTS: We analyzed 95 children with liver injury in whom a blood lactate measurement on admission was available. Eighty children (84%) were aged <2 years; 49 children (52%) died during hospitalization. The median acetaminophen concentration on admission was 20 mg/L with 60 (70%) children presenting concentrations exceeding 10 mg/L. Median lactate was significantly higher in children who died (10.7 mmol/L; interquartile range (IQR): 8.5-15.7) than those who survived (6.1 mmol/L; IQR: 4.1-8.5), P value < 0.001). The optimal threshold obtained was 7.2 mmol/L with a sensitivity of 84% and specificity 70% (area under curve = 0.80). The previously established thresholds of 3.5 and 4 mmol/L lactate had very low specificity identifying non-survival in children included in this study. CONCLUSION: In this setting, young children with ALF possibly attributed to acetaminophen toxicity were unlikely to survive if the venous blood lactate concentration exceeded 7.2 mmol/L.
A screening tool for psychological difficulties in children aged 6 to 36 months: cross-cultural validation in Kenya, Cambodia and Uganda.Nackers, F; Roederer, T; Marquer, C; Ashaba, S; Maling, S; Mwanga-Amumpaire, J; Muny, S; Sokeo, C; Shom, V; Palha, M; et al. (BioMed Central, 2019-04-12)In low-resource settings, the lack of mental health professionals and cross-culturally validated screening instruments complicates mental health care delivery. This is especially the case for very young children. Here, we aimed to develop and cross-culturally validate a simple and rapid tool, the PSYCa 6-36, that can be administered by non-professionals to screen for psychological difficulties among children aged six to 36 months. A primary validation of the PSYCa 6-36 was conducted in Kenya (n = 319 children aged 6 to 36 months; 2014), followed by additional validations in Kenya (n = 215; 2014) Cambodia (n = 189; 2015) and Uganda (n = 182; 2016). After informed consent, trained interviewers administered the PSYCa 6-36 to caregivers participating in the study. We assessed the psychometric properties of the PSYCa 6-36 and external validity was assessed by comparing the results of the PSYCa 6-36 against a clinical global impression severity [CGIS] score rated by an independent psychologist after a structured clinical interview with each participant. The PSYCa 6-36 showed satisfactory psychometric properties (Cronbach's alpha > 0.60 in Uganda and > 0.70 in Kenya and Cambodia), temporal stability (intra-class correlation coefficient [ICC] > 0.8), and inter-rater reliability (ICC from 0.6 in Uganda to 0.8 in Kenya). Psychologists identified psychological difficulties (CGIS score > 1) in 11 children (5.1%) in Kenya, 13 children (8.7%) in Cambodia and 15 (10.5%) in Uganda, with an area under the receiver operating characteristic curve of 0.65 in Uganda and 0.80 in Kenya and Cambodia. The PSYCa 6-36 allowed for rapid screening of psychological difficulties among children aged 6 to 36 months among the populations studied. Use of the tool also increased awareness of children's psychological difficulties and the importance of early recognition to prevent long-term consequences. The PSYCa 6-36 would benefit from further use and validation studies in popula`tions with higher prevalence of psychological difficulties.
