The Bacterial Biofilms: Formation, Impacts, and Possible Management Targets in the Healthcare System.

The persistent increase in multidrug-resistant pathogens has catalyzed the creation of novel strategies to address antivirulence and anti-infective elements. Such methodologies aim to diminish the selective pressure exerted on bacterial populations, decreasing the likelihood of resistance emergence. This review explores the role of biofilm formation as a significant virulence factor and its impact on the development of antimicrobial resistance (AMR).

Change in Blood Pressure, Weight, and Other Cardiovascular Disease Risk Factors After Switch From Protease Inhibitors to Dolutegravir: Post hoc Analysis of the 48-week Randomised Second-line Switch to Dolutegravir Trial.

Among 777 virally suppressed adults with human immunodeficiency virus on protease-inhibitor-based second-line antiretroviral regimens randomized 1:1 to switch to dolutegravir or remain on a protease inhibitor, there was no difference in incident hypertension (12% in each arm, P = .868) or change in blood pressure over the 48-week study period.

Prospective clinical surveillance for severe acute respiratory illness and COVID-19 vaccine effectiveness in Kenyan hospitals during the COVID-19 pandemic.

Background: There are limited data from sub-Saharan Africa describing the demographic characteristics, clinical features and outcome of patients admitted to public hospitals with severe acute respiratory infections during the COVID-19 pandemic.

Methods: We conducted a prospective longitudinal hospital-based sentinel surveillance between May 2020 and December 2022 at 16 public hospitals in Kenya. All patients aged above 18 years admitted to adult medical wards in the participating hospitals were included.

UNITY: A low-field magnetic resonance neuroimaging initiative to characterize neurodevelopment in low and middle-income settings.

Measures of physical growth, such as weight and height have long been the predominant outcomes for monitoring child health and evaluating interventional outcomes in public health studies, including those that may impact neurodevelopment. While physical growth generally reflects overall health and nutritional status, it lacks sensitivity and specificity to brain growth and developing cognitive skills and abilities. Psychometric tools, e.

Monitoring the battleground: exploring antimicrobial resistance and virulence factors in wound bacterial isolates.

Antibiotic resistance poses a grave global public health threat, exacerbated by widespread and often inappropriate antibiotic usage. Vigilant surveillance of antibiotic utilization and emergence of antimicrobial resistance (AMR) is essential. Of particular concern in the era of AMR is the persistent issue of chronic wound infections.

Decentralizing cancer care in sub-Saharan Africa through an integrated regional cancer centre model: The case of Kenya.

For 50 years, comprehensive cancer treatment services were provided at one public hospital and a few private facilities in the capital city. In 2019, the services were decentralized to new national and regional centers to increase service accessibility using an integration model. This study aimed to analyze the status of the utilization of services at regional cancer centers.

Growth and neurodevelopmental outcomes of preterm and low birth weight infants in rural Kenya: a cross-sectional study.

Objective: Data on long-term outcomes of preterm (PT) and low birth weight (LBW) infants in countries with high rates of neonatal mortality and childhood stunting are limited, especially from community settings. The current study sought to explore growth and neurodevelopmental outcomes of PT/LBW infants from a rural community-based setting of Kenya up to 18 months adjusted age.

Design: Cross-sectional study.

Second-Line Switch to Dolutegravir for Treatment of HIV Infection.

Background: Data to inform the switch from a ritonavir-boosted protease inhibitor (PI) to dolutegravir in patients living with human immunodeficiency virus (HIV) infection who do not have genotype information and who have viral suppression with second-line therapy containing a ritonavir-boosted PI have been limited.

Methods: In a prospective, multicenter, open-label trial conducted at four sites in Kenya, we randomly assigned, in a 1:1 ratio, previously treated patients without genotype information who had viral suppression while receiving treatment containing a ritonavir-boosted PI to either switch to dolutegravir or continue the current regimen. The primary end point was a plasma HIV type 1 RNA level of at least 50 copies per milliliter at week 48, assessed on the basis of the Food and Drug Administration snapshot algorithm.

Access to essential cancer medicines for children: a comparative mixed-methods analysis of availability, price, and health-system determinants in east Africa.

Background: Access to essential childhood cancer medicines is a core determinant of childhood cancer outcomes. Available evidence, although scarce, suggests that access to these medicines is highly variable across countries, particularly in low-income and middle-income countries, where the burden of childhood cancer is greatest. To support evidence-informed national and regional policies for improved childhood cancer outcomes, we aimed to analyse access to essential childhood cancer medicines in four east African countries-Kenya, Rwanda, Tanzania, and Uganda-by determining the availability and price of these medicines and the health system determinants of access.

Endemic Burkitt lymphoma avatar mouse models for exploring inter-patient tumor variation and testing targeted therapies.

Endemic Burkitt lymphoma (BL) is a childhood cancer in sub-Saharan Africa characterized by Epstein-Barr virus and malaria-associated aberrant B-cell activation and chromosomal translocation. Survival rates hover at 50% after conventional chemotherapies; therefore, clinically relevant models are necessary to test additional therapies. Hence, we established five patient-derived BL tumor cell lines and corresponding NSG-BL avatar mouse models.

Molecular surveillance reveals widespread colonisation by carbapenemase and extended spectrum beta-lactamase producing organisms in neonatal units in Kenya and Nigeria.

Objectives: Neonatal sepsis, a major cause of death amongst infants in sub-Saharan Africa, is often gut derived. Gut colonisation by Enterobacteriaceae producing extended spectrum beta-lactamase (ESBL) or carbapenemase enzymes can lead to antimicrobial-resistant (AMR) or untreatable infections. We sought to explore the rates of colonisation by ESBL or carbapenemase producers in two neonatal units (NNUs) in West and East Africa.

Prospective observational study of the challenges in diagnosing common neonatal conditions in Nigeria and Kenya.

Objectives: Accurate and timely diagnosis of common neonatal conditions is crucial for reducing neonatal deaths. In low/middle-income countries with limited resources, there is sparse information on how neonatal diagnoses are made. The aim of this study was to describe the diagnostic criteria used for common conditions in neonatal units (NNUs) in Nigeria and Kenya.

The Consortium on Newborn Screening in Africa for sickle cell disease: study rationale and methodology.

Sickle cell disease (SCD) is a common condition within sub-Saharan Africa and associated with high under-5 mortality (U5M). The American Society of Hematology instituted the Consortium on Newborn Screening in Africa (CONSA) for SCD, a 7-country network of sites to implement standardized newborn hemoglobinopathy screening and early intervention for children with SCD in sub-Saharan Africa. CONSA's overall hypothesis is that early infant SCD screening and entry into standardized, continuous care will reduce U5M compared with historical estimates in the region.

Virtual Faculty Development in Simulation in Sub-Saharan Africa: A Pilot Training for Pediatricians in Kisumu, Kenya.

Introduction: Simulation is an effective educational tool increasingly being utilized in medical education globally and across East Africa. Globally, pediatric patients often present with low frequency, high acuity disease and simulation-based training in pediatric emergencies can equip physicians with the skills to recognize and intervene. Northwestern University (NU) in Chicago, IL, USA, and Maseno University (MU), in Kisumu, Kenya launched a predominantly virtual partnership in 2020 to utilize the Jaramogi Oginga Odinga Teaching & Referral Hospital (JOOTRH) simulation center for MU faculty development in simulation based medical education (SBME) for medical students.

All-cause and cause-specific mortality rates for Kisumu County: a comparison with Kenya, low-and middle-income countries.

Background: Understanding the magnitude and causes of mortality at national and sub-national levels for countries is critical in facilitating evidence-based prioritization of public health response. We provide comparable cause of death data from Kisumu County, a high HIV and malaria-endemic county in Kenya, and compared them with Kenya and low-and-middle income countries (LMICs).

Methods: We analyzed data from a mortuary-based study at two of the largest hospital mortuaries in Kisumu.

Aim: To assess feeding practices in Nigeria and Kenya for very preterm and VLBW newborn infants.

Methods: This was a cross-sectional study where convenience sampling was used.

Barriers and Facilitators to Integrating Clinical Breast Examinations With Cervical Cancer Screening Programs in Outpatient Clinics in Western Kenya.

Purpose: Nearly half of Kenyan women with breast cancer present with advanced disease-owing partially to limited patient education and screening limitations in low- and middle-income countries. With increasing access to nurse-led cervical cancer screening (CCS) in government clinics in Kenya, we investigated provider-perceived barriers and facilitators to integrating clinical breast examinations (CBEs) with ongoing CCS programs in Kisumu County, Kenya.

Methods: CCS providers within the Ministry of Health Clinics in Kisumu County, Kenya, were recruited to participate in a two-phase, sequential, mixed methods study.

Interplay between IL-10, IFN-γ, IL-17A and PD-1 Expressing EBNA1-Specific CD4 and CD8 T Cell Responses in the Etiologic Pathway to Endemic Burkitt Lymphoma.

Children diagnosed with endemic Burkitt lymphoma (eBL) are deficient in interferon-γ (IFN-γ) responses to Epstein-Barr Nuclear Antigen1 (EBNA1), the viral protein that defines the latency I pattern in this B cell tumor. However, the contributions of immune-regulatory cytokines and phenotypes of the EBNA1-specific T cells have not been characterized for eBL. Using a bespoke flow cytometry assay we measured intracellular IFN-γ, IL-10, IL-17A expression and phenotyped CD4 and CD8 T cell effector memory subsets specific to EBNA1 for eBL patients compared to two groups of healthy children with divergent malaria exposures.
