Maternal and neonatal IgG against Klebsiella pneumoniae are associated with lower risk of neonatal sepsis: A case-control study of hospitalized neonates in Botswana.

Sepsis is the leading postnatal cause of neonatal mortality worldwide. Globally Klebsiella pneumoniae is the leading cause of sepsis in hospitalized neonates. This study reports the development and evaluation of an ELISA for anti-Klebsiella IgG using dried blood spot (DBS) samples and evaluates the association of anti-Klebsiella IgG (anti-Kleb IgG) antibodies in maternal and neonatal samples with the risk of neonatal sepsis.

Core Content, Competencies, and Accreditation in US Global Health Fellowships: A Survey of Leaders' Perspectives.

The number of global health (GH) fellowships in the United States has increased over the past two decades. However, there are currently no standard requirements, shared core content, or widespread systems of accreditation. With the growth in programs, it is appropriate to consider these issues.

The role of the microbiota in respiratory virus-bacterial pathobiont relationships in the upper respiratory tract.

The mechanisms by which respiratory viruses predispose to secondary bacterial infections remain poorly characterized. Using 2,409 nasopharyngeal swabs from 300 infants in Botswana, we performed a detailed analysis of factors that influence the dynamics of bacterial pathobiont colonization during infancy. We quantify the extent to which viruses increase the acquisition of , , and .

sp. nov., isolated from human upper respiratory samples collected in Botswana.

Four strains (MSK211, MSK294, MSK312, MSK433) of a novel species were cultured from nasopharyngeal swabs collected from mother-infant dyads in southern Botswana. These strains grew optimally on tryptic soy agar with 5% sheep blood solid medium and in fastidious bacteria broth. Colonies on tryptic soy agar with 5% sheep blood agar appeared grey or white with a flat, smooth surface and variable alpha haemolysis.

Attitudes of pregnant women in the Dominican Republic towards a future maternal Group B Streptococcus vaccine.

Introduction: Current protocols aim to prevent some infant GBS infection through screening and peripartum antibiotics, however such strategies cannot be widely implemented in resource-limited settings. On the other hand, maternal vaccines in development against Group B Streptococcus (GBS) can provide a feasible universal approach. The success of any vaccine will depend on uptake in the population.

Serotype epidemiology and antibiotic resistance of pneumococcal isolates colonizing infants in Botswana (2016-2019).

Background: In 2012, Botswana introduced 13-valent pneumococcal conjugate vaccine (PCV-13) to its childhood immunization program in a 3+0 schedule, achieving coverage rates of above 90% by 2014. In other settings, PCV introduction has been followed by an increase in carriage or disease caused by non-vaccine serotypes, including some serotypes with a high prevalence of antibiotic resistance.

Methods: We characterized the serotype epidemiology and antibiotic resistance of pneumococcal isolates cultured from nasopharyngeal samples collected from infants (≤12 months) in southeastern Botswana between 2016 and 2019.

Management of the infant born to a mother with tuberculosis: a systematic review and consensus practice guideline.

Infants born to mothers with tuberculosis disease are at increased risk of developing tuberculosis disease themselves. We reviewed published studies and guidelines on the management of these infants to inform the development of a consensus practice guideline. We searched MEDLINE, CINAHL, and Cochrane Library from database inception to Dec 1, 2022, for original studies reporting the management and outcome of infants born to mothers with tuberculosis.

Etiologies of Mild and Moderate Diarrheal Illness among Children in Consuelo, Dominican Republic.

Since the rotavirus vaccine was included in the Dominican Republic's national immunization schedule in 2012, the microbiologic etiologies of acute gastroenteritis have not been described. This study aimed to determine the contribution of rotavirus as an etiology of acute gastroenteritis over a 12-month period in children under 5 years of age in both an inpatient and an outpatient setting in Consuelo, Dominican Republic. All children who were seen at Niños Primeros en Salud clinic or admitted to Hospital Municipal Dr.

Genomic Analysis of Group B Carriage Isolates From Botswana Reveals Distinct Local Epidemiology and Identifies Novel Strains.

In pregnant people colonized with group B (GBS) in Botswana, we report the presence/expansion of sequence types 223 and 109, a low rate of erythromycin resistance, and 3 novel sequence types. These data highlight the importance of local epidemiologic studies of GBS, a significant source of neonatal disease.

Factors Associated With Initiating Breastfeeding and Continuing it for At Least 4 Months in Consuelo, a Rural Town in the Dominican Republic.

. We assessed the proportion of and factors associated with mothers initiating and continuing breastfeeding (BF) for ≥4 months in a rural town of the Dominican Republic. A survey was administered to 190 mothers of children cared for at a free clinic in Consuelo.

Near-term pregnant women in the Dominican Republic experience high rates of Group B Streptococcus rectovaginal colonization with virulent strains.

Maternal colonization with Group B Streptococcus (GBS) is an important cause of stillbirth, prematurity, and serious infection and death in infants worldwide. Resource constraints limit prevention strategies in many regions. Maternal GBS vaccines in development could be a more accessible prevention strategy, but data on geographic variations in GBS clones are needed to guide development of a broadly effective vaccine.

Under-Reporting of Tuberculosis Disease among Children and Adolescents in Low and Middle-Income Countries: A Systematic Review.

Under-reporting of tuberculosis (TB) disease in children and adolescents is a significant global concern, as many children are missing from TB notification data. A systematic literature review was conducted to understand the global reporting gap of child and adolescent TB as well as current interventions to close this gap in Low- and Middle- Income Countries (LMIC). Our study found large and variable gaps in child and adolescent TB reporting, due to various factors.

Assessing antibiotic utilization among pediatric patients in Gaborone, Botswana.

Objectives: Over the past decade, concerning trends in antimicrobial resistance have emerged in Southern Africa. Given a paucity of pediatric data, our objectives were to (1) describe antibiotic utilization trends at a national referral center in Southern Africa and (2) assess the proportion of patients receiving antibiotics appropriately. In addition, risk factors for inappropriate use were explored.

Maternity care provider acceptance of a future Group B Streptococcus vaccine - A qualitative study in three countries.

Introduction: There are vaccines in clinical trials that target the bacterium Group B Streptococcus (GBS). When approved, GBS vaccines will be intended for administration to pregnant women to prevent infection in their infants. The success of any vaccine will depend on its' uptake in the population.

Severity of illness and mortality among children admitted to a tertiary referral hospital in Botswana: A secondary data analysis of a prospective cohort study.

Objectives: Data on triage practices of children admitted to Princess Marina Hospital in Gaborone, Botswana is limited. The inpatient triage, assessment, and treatment score was developed for low resource settings to predict mortality in children. We assess its performance among children admitted to Princess Marina Hospital and their demographic, clinical, and risk factors for death.

Risk factors for mortality in a hospitalised neonatal cohort in Botswana.

Objectives: A disproportionate number of neonatal deaths occur in low/middle-income countries, with sepsis a leading contributor of mortality. In this study, we investigate risk factors for mortality in a cohort of high-risk hospitalised neonates in Botswana. Independent predictors for mortality for infants experiencing either a sepsis or a non-sepsis-related death are described.

Kinetics of pneumococcal antibodies among HIV-exposed, uninfected infants in Botswana.

Background: Streptococcus pneumoniae is a leading cause of severe infections among children. Despite vaccination, HIV-exposed, uninfected (HEU) children have a higher incidence of invasive pneumococcal disease than HIV-unexposed, uninfected (HUU) children. We sought to compare the immunogenicity of 13-valent pneumococcal conjugate vaccine (PCV-13) in HEU and HUU infants.

Skin conditions among pediatric dermatology outpatients in Botswana.

Background: An understanding of the prevalence patterns of skin diseases in children in Botswana is needed to guide national dermatological policy development, training, and resource allocation to improve patient care.

Objective: To describe local skin disease patterns in children aged 0-18 years presenting for dermatologic care in Botswana.

Methods: A retrospective review of records from 1st January 2011 to 31st December 2016 was conducted at the outpatient dermatology clinic of Princess Marina Hospital (PMH) in Gaborone, Botswana and outreach clinic sites.

Optimising the management of childhood acute diarrhoeal disease using a rapid test-and- treat strategy and/or DSM 17938: a multicentre, randomised, controlled, factorial trial in Botswana.

Introduction: The study aim was to determine if rapid enteric diagnostics followed by the provision of targeted antibiotic therapy ('test-and-treat') and/or DSM 17938 would improve outcomes in children hospitalised in Botswana with acute gastroenteritis.

Methods: This was a multicentre, randomised, factorial, controlled, trial. Children aged 2-60 months admitted for acute non-bloody diarrhoea to four hospitals in southern Botswana were eligible.

The perceptions and practices of parents and children on acute pain management among hospitalized children in two Botswana referral hospitals.

Background: Perceptions and practices of parties in pediatric pain are critical in children's access to adequate acute pain management. The personal factors of the child and parents have been shown to be central to pediatric pain management by the Symptom Management Theory.

Aim: To describe children and parents/guardians' perceptions (knowledge, attitudes and beliefs) and practices regarding pediatric acute pain management and explain the influence of socio-cultural and environmental factors on those perceptions and practices.
