Reducing under-five mortality is a crucial indicator of overall development in a country. However, in Angola, understanding the factors contributing to hospital deaths in this vulnerable demographic remains incomplete despite improvements in healthcare infrastructure and public health policies. With one of the highest under-five mortality rates in sub-Saharan Africa, Angola faces significant challenges such as malaria, malnutrition, pneumonia, neonatal conditions, and intestinal infectious diseases, which are the leading causes of death among children. This study aimed to identify factors associated with hospital deaths among children aged 28 days to five years admitted to DBPH in Luanda between May 2022 and June 2023. Using a hospital-based case-control design, the study included 1020 children, among whom 340 experienced hospital deaths. Distal and intermediate determinants emerged as primary predictors of hospital mortality, showing significant associations with: mother without schooling (OR [95%CI] 4.3 [1.2-15.7], p < 0.027); frequent alcohol consumption during pregnancy (OR [95%CI] 3.8 [2.5-5.9], p < 0.001); hospital stay ≤24 h (OR [95%CI] 13.8 [6.2-30.8], p < 0.001); poor nutritional status (OR [95%CI] 2.1 [1.4-3.2], p < 0.001); short interbirth interval (OR [95%CI] 1.7 [1.1-2.5], p < 0.014); maternal age ≤19 years (OR [95%CI] 5.6 [3.0-10.8], p < 0.001); and maternal age ≥35 years (OR [95%CI] 2.1 [1.2-3.7], p < 0.006). These findings highlight the preventable nature of most under-five hospital deaths and underscore the urgent need to address social inequities and improve the quality of primary healthcare services to effectively reduce child mortality in Angola.

TB remains an important cause of childhood morbidity and mortality. Underdiagnosis, underreporting and limited data on the outcomes of childhood TB have led to an underestimation of its impact.This was a systematic review to characterise childhood TB outcomes. Studies reporting relevant epidemiological data on children between 0 and 14 years of age, with a particular focus on treatment outcomes, from countries with universal bacilli Calmette-Guérin (BCG) vaccination and conducted between 2000 and 2020 were selected. Random effects meta-analysis was performed in R software.We identified 1,806 references and included 35 articles. Among children with TB, the overall proportion of unfavourable outcomes was 19.5% (95% CI 14.4-25.8) and pooled case-fatality ratio was 6.1% (95% CI 4.3-8.4). The proportion of deaths observed among children between 0 and 4 years old was 6.6% (95% CI 4.9-8.7) and 4.6% (95% CI 3.1-6.9) in older children. TB and HIV co-infected children presented a case-fatality ratio of 15.1% (95% CI 7.9-27.0).Despite the efforts made in the last decades, treatment outcomes in childhood TB are still worrisome. Efforts to fill existing gaps and design health policies targeting vulnerable populations, such as children, should be intensified to tackle the global TB burden..

Mycetoma is caused by the subcutaneous inoculation of filamentous fungi or aerobic filamentous bacteria. Cellulosimicrobium cellulans is a gram-positive bacterium from the order Actinomycetales that rarely causes human disease. The diagnosis is based on the clinical presentation and identification of the causative microorganism. We present a short literature review regarding the case report of a young man diagnosed with actinomycetoma due to Cellulosimicrobium cellulans and who received treatment with an association of amikacin and sulfamethoxazole/ trimethoprim (Welsh regimen).

Background: Osteoarticular infections (OAI) are associated with complications and sequelae in children, whose prediction are of great importance in improving outcomes. We aimed to design risk prediction models to identify early complications and sequelae in children with OAI., Methods: This observational study included children (>3 months-17 years old) with acute OAI admitted to a tertiary-care pediatric hospital between 2008 and 2018. Clinical treatment, complications and sequelae were recorded. We developed a multivariable logistic predictive model for an acute complicated course (ACC) and another for sequelae., Results: A total of 240 children were identified, 17.5% with ACC and 6.0% and 3.6% with sequelae at 6 and 12 months of follow-up, respectively. In the multivariable logistic predictive model for ACC, predictors were fever at admission [adjusted odds ratio (aOR): 2.98; 95% confidence interval (CI): 1.10-8.12], C-reactive protein ≥100 mg/L (aOR: 2.37; 95% CI: 1.05-5.35), osteomyelitis (aOR: 4.39; 95% CI: 2.04-9.46) and Staphylococcus aureus infection (aOR: 3.50; 95% CI: 1.39-8.77), with an area under the ROC curve of 0.831 (95% CI: 0.767-0.895). For sequelae at 6 months, predictors were age ≥4 years (aOR: 4.08; 95% CI: 1.00-16.53), C-reactive protein ≥110 mg/L (aOR: 4.59; 95% CI: 1.25-16.90), disseminated disease (aOR: 9.21; 95% CI: 1.82-46.73) and bone abscess (OR: 5.46; 95% CI: 1.23-24.21), with an area under the ROC curve of 0.887 (95% CI: 0.815-0.959)., Conclusions: In our model we could identify patients at low risk for complications and sequelae, probably requiring a less aggressive approach., Competing Interests: The authors have no funding or conflicts of interest to disclose., (Copyright © 2023 Wolters Kluwer Health, Inc.

Several cases of paediatric acute hepatitis of an unknown aetiology have been described in these last few months and in several countries worldwide. We present two patients, a 7-month-old girl and an 8-year-old boy, with gastrointestinal symptoms and lethargy, associated with elevation of transaminase levels. Serologies for hepatitis A-E virus and PCR test to SARS-CoV-2 were all negative. In the first case, an adenovirus serotype C could be isolated in a respiratory sample as well as cytomegalovirus (CMV) in the blood (100 copies/mL). In both children, there was a progressive decrease in the hepatic markers and symptomatic resolution, compatible with a good prognosis, also seen globally in most cases. To date, infection remains the most plausible cause to consider, especially when it is presumed to be linked to adenovirus. Other potential agents and causes are still being evaluated, thus emphasizing the importance of continuous epidemiological surveillance, notification, and detailed study of all hepatitis cases.

Globally, anaemia prevails as a public health issue, being also a concern in Mozambique, where about two-thirds of children 6-59 months of age are affected by this condition. We carried out this study to estimate anaemia prevalence and evaluate structural determinants and haematological parameters association among children aged 6-59 months attending pediatric inpatient and outpatient services in a Quaternary Health Facility in Maputo City Province, Mozambique. We collected data from 637 inpatients or outpatients who attended pediatric consultations at the Maputo Central Hospital. The overall rate of anaemia in children aged 6-59 months was 62.2% (396/637), with 30.9% moderate anaemia (197/637), 23.9% mild anaemia (152/637), and 7.4% severe anaemia (47/637). Among our study participants, critical factors for anaemia were those concerning the age group, child´s caregiver schooling, malaria and size of the liver.

Introduction. Bone and joint tuberculosis (BJTB) is rare in developed countries, particularly in the paediatric population. Hypothesis/Gap Statement. The clinical features and sequelae of paediatric BJTB in Europe are not well characterized and should be assessed to achieve a better approach. Aim. To assess the management and outcomes of paediatric BJTB. Methodology. Longitudinal observational study of all paediatric patients (0-17 years old) diagnosed with BJTB between 2008 to 2020 in a tertiary-care hospital. Results. We identified 18 patients with BJTB, with a median age of 10 years (IQR 6-14.8), 66.7 % male. Most (72 %) were diagnosed after 2015 and were foreign-born (88.9 %), mainly from Portuguese-speaking African countries, and none had HIV. The most common symptoms were pain (77.8 %), fever (50 %) and bone deformity (44.4 %). Spinal TB (STB) affected 13 (72.2 %) and extra-spinal TB (ESTB) 9 (50 %) patients, and 4 (27.7 %) had both conditions. Diagnostic positive procedures included positive nucleic acid amplification technique (NAAT) (44.4 %), Mycobacterium tuberculosis isolation (44.4 %) and compatible histology (33.3 %). All completed antituberculous drugs for a median of 12 months (IQR 12-13) and nine (50 %) had surgery. Overall, acute complications occurred in 16 (88.9 %) patients - 11/13 (84.6 %) with STB and 5/5 (100 %) with ESTB - and included abscesses, spinal compression, spine deformity and pathological fractures. Sequelae were still present at the 12-month follow-up in seven cases (46.7 %), and were more common in foreign-born patients sent to Portugal to receive medical treatment (66.7 vs 20 %). Conclusions. Paediatric BJTB is difficult to diagnose and has high morbidity, requiring long-term follow-up. Over the last decade, foreign-born TB seems to be increasing, with still longer treatment courses and more acute complications and sequelae.

Introduction: Globally, anemia is still a public health issue faced by people in low and high-income countries. This study gives an overview of published scientific articles related to the prevalence, nutritional indicators, and social determinants of anemia in pregnant women and children aged 6 to 59 months living in Mozambique and Portugal., Methods: We performed a review of scientific literature in April 2021, searching for published indexed articles in the last 15 years (2003-2018) in electronic databases. Subsequently, quality assessment, data extraction, and content analysis were performed., Results: We have identified 20 relevant publications. Unsurprisingly, anemia plays a relevant role in disability and life imbalances for these subgroups in Mozambique compared with Portugal. For both countries, data on anemia and iron deficiency in pregnant women and children aged 6 to 59 months old are either outdated or remain unclear. Similarly, studies on social determinants and anemia are also still scarce., Conclusions: A gap of information on anemia, other nutritional indicators, and social determinants in pregnant women and children between 6 and 59 months of age living in Mozambique and Portugal is highly observed. More research is crucial to help achieve the goals established by the Sustainable Development Goals.

Background: There has been tremendous progress in the fight against HIV worldwide; however, challenges persist in the control of HIV infection. These challenges include the high prevalence of late presenters. There are many disadvantages of late presentation-from reduced survival of the infected person to the risk of transmitting the infection. This research aims to analyze the factors that influence the late presentation in patients attending Ndlavela Health Center in Mozambique., Methodology: A retrospective cross-sectional study was carried out at Ndlavela Health Center including patients diagnosed with HIV between 2015 and 2020. The European Late Presenter Consensus working group definitions were used, and univariate and multivariate logistic regression were used to identify factors associated with late presentation., Results: In total, 519 participants were included in the study, of which nearly 47% were classified as late presenters. The male gender (AOR = 2.41), clinical suspicious test (AOR = 4.03), initiated by the health professional (AOR = 2.1,9), and fear of stigma (AOR = 2.80) were the main risk factors for late HIV presentation., Conclusion: Factors that are potentially determinant for late HIV presentation were identified. Actions are needed to focus on risk factors that are most likely to delay presentation.

Malaria is a parasitic disease of which Plasmodium falciparum causes the most severe form of the disease. The immune response against Plasmodium spp. is complex and remains unclear. The present report aimed to better understand the humoral immune response in severe malaria and analyse new immunodominant antigen candidates as possible serological marker in severe malaria in children. This study included children aged 0-16 years from Guinea-Bissau with clinical signs of severe malaria. Serological and immunochemical characterisation of different anti-P. falciparum antibodies were made by ELISA and immunoblotting using a crude protein extract of P. falciparum. Sera from 12 children with severe malaria were analysed. Nine samples were positive for total anti-P. falciparum antibodies, seven for IgM and eight for total IgG anti-P. falciparum. There was a predominance of IgG1 response, suggesting a cytophilic action in severe malaria and a major role of IgG1 over other immunoglobulins. The antigenic profile of P. falciparum showed a consistent immunoblotting pattern of approximately 180 kDa, 100 kDa and around 50-40 kDa. The serological reactivity found in protein bands makes them as immunodominant antigens and promising candidates for serological markers in the context of severe malaria., (Copyright © 2018 Elsevier B.V.

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are rare but serious dermatologic diseases with many potential multisystem complications. We describe the case of an 8-year-old girl who developed severe SJS/TEN overlap syndrome (25% of her body surface area was affected) complicated by pancreatitis and bronchiolitis obliterans. These rare complications emphasize the need for careful, intensive monitoring of possible complications and an interdisciplinary team approach to provide optimal treatment and follow-up., (© 2017 Wiley Periodicals, Inc.)
