Article Synopsis
  • A systematic review was conducted to evaluate the effectiveness of probiotics for managing acute and persistent diarrhea in children, as current WHO guidelines do not recommend their use.
  • The review included 98 studies with over 17,000 participants, revealing that probiotics may slightly improve clinical outcomes for acute diarrhea but showed high variability and low certainty in results.
  • For persistent diarrhea, probiotics were associated with a significant reduction in the duration of symptoms, demonstrating potential benefits though confidence in the findings remains low.

Background: Oral rehydration solution (ORS) is crucial in the management of diarrhoea. Until the early 2000s, the standard formulation of glucose-based ORS with a total osmolarity of 311 mmol/L was being used for this purpose. However, due to concerns about sodium levels and cases of hypernatremia, a low-osmolarity ORS solution (LORS) with an osmolarity of 245mmol/L or less was developed to replace the standard ORS.

Background: Neonatal infections are a major public health concern worldwide, particularly in low- and middle-income countries, where most of the infection-related deaths in under-five children occur. Sub-Saharan Africa has the highest mortality rates, but there is a lack of data on the incidence of sepsis from this region, hindering efforts to improve child survival. We aimed to determine the incidence of possible serious bacterial infection (PSBI) in young infants in three high-burden countries in Africa.

Background: Information on the average and incremental costs of implementing alternative strategies for treating young infants 0-59 days old in primary health facilities with signs of possible serious bacterial infection (PSBI) when a referral is not feasible is limited but valuable for policymakers.

Methods: Direct activity costs were calculated for outpatient treatment of PSBI and pneumonia in two districts of India: Palwal, Haryana and Lucknow, Uttar Pradesh. These included costs of staff time and consumables for initial assessment, classification, and referrals; recommended treatment of fast breathing (oral amoxicillin for seven days) and PSBI (injection gentamicin and oral amoxicillin for seven days); and daily assessments.

Article Synopsis
  • The study assessed the impact of pulse oximetry on mortality rates in children hospitalized with pneumonia, finding that it significantly reduced case fatality risk (CFR) from 5.8% to 2.1%).
  • Among the studied children, nearly 20% with chest-indrawing pneumonia were hypoxemic, leading to a 10.3% CFR for those cases, highlighting the critical need for monitoring oxygen levels.
  • Key mortality risk factors identified included younger age, moderate malnutrition, and female sex; the findings suggest that integrating pulse oximetry into pneumonia care for children under 5 is vital.

Background: The existing World Health Organization (WHO) pneumonia case management guidelines rely on clinical symptoms and signs for identifying, classifying, and treating pneumonia in children up to 5 years old. We aimed to collate an individual patient-level data set from large, high-quality pre-existing studies on pneumonia in children to identify a set of signs and symptoms with greater validity in the diagnosis, prognosis, and possible treatment of childhood pneumonia for the improvement of current pneumonia case management guidelines.

Methods: Using data from a published systematic review and expert knowledge, we identified studies meeting our eligibility criteria and invited investigators to share individual-level patient data.

Introduction: Neonates with serious bacterial infections should be treated with injectable antibiotics after hospitalization, which may not be feasible in many low resource settings. In 2015, the World Health Organization (WHO) launched a guideline for the management of young infants (0-59 days old) with possible serious bacterial infection (PSBI) when referral for hospital treatment is not feasible. We evaluated the feasibility of the WHO guideline implementation in the Democratic Republic of the Congo (DRC) to achieve high coverage of PSBI treatment.

Introduction: Serious bacterial neonatal infections are a major cause of global neonatal mortality. While hospitalized treatment is recommended, families cannot access inpatient treatment in low resource settings. Two parallel randomized control trials were conducted at five sites in three countries (Democratic Republic of Congo, Kenya, and Nigeria) to compare the effectiveness of treatment with experimental regimens requiring fewer injections with a reference regimen A (injection gentamicin plus injection procaine penicillin both once daily for 7 days) on the outpatient basis provided to young infants (0-59 days) with signs of possible serious bacterial infection (PSBI) when the referral was not feasible.
