Strengthening the relationship between community resilience and health emergency communication: a systematic review.

Background: Community resilience and health emergency communication are both crucial in promoting a community's ability to endure crises and recover from emergency events. Yet, a notable gap in theory and evidence exists in the relationship between them. We aim to explore the relationship between community resilience and health emergency communication and to identify strategies and interventions to strengthen their usefulness to each other.

Integration of HIV pre-exposure prophylaxis (PrEP) services for pregnant and breastfeeding women in eight primary care clinics: results of an implementation science study.

Background: Although HIV vertical transmission has declined significantly in sub-Saharan Africa, incident HIV infection in pregnant and postpartum women is estimated to account for over one-third of HIV vertical transmission. Oral pre-exposure prophylaxis (PrEP) for pregnant and breastfeeding women (PBFW) is included in South African PrEP guidelines since 2021; however, integration of PrEP services within ante- and postnatal care remains limited.

Methods: Between March 2022 and September 2023, we evaluated the integration of PrEP for PBFW in eight antenatal clinics in Cape Town, South Africa, following training and mentorship of providers.

Health System Factors Influencing the Integration of Pre-Exposure Prophylaxis into Antenatal and Postnatal Clinic Services in Cape Town, South Africa.

Introduction: Oral pre-exposure prophylaxis (PrEP) is an effective and safe option to prevent HIV acquisition and vertical HIV transmission in pregnant and breastfeeding women. Understanding health system factors influencing the integration of PrEP into care for pregnant and breastfeeding women is key to increasing access. We explored managers' and health care workers' (HCWs) experiences with integrating PrEP into antenatal care and postnatal care services in primary health care clinics in Cape Town, South Africa.

Initiation and continued use of oral pre-exposure prophylaxis among pregnant and postpartum women in South Africa (PrEP-PP): a demonstration cohort study.

Background: When used effectively, oral pre-exposure prophylaxis (PrEP; tenofovir disoproxil fumarate and emtricitabine) prevents maternal HIV acquisition and reduces the risk of vertical transmission. Our study aimed to better understand PrEP initiation, continued use, and adherence in pregnant and postpartum women.

Methods: The PrEP in Pregnancy and Postpartum (PrEP-PP) study is a demonstration cohort study that enrolled pregnant women aged 16 years and older without HIV attending their first antenatal care visit in Cape Town, South Africa, between Aug 29, 2019, and Oct 10, 2021.

Management of iron overload: lessons from transfusion-dependent hemoglobinopathies.

Prior to the advent of effective iron chelation, death from iron-induced cardiomyopathy and endocrine failure occurred in the second decade in patients with thalassemia major and this experience has driven expectation of poor outcomes and caused anxiety in all disorders associated with iron loading to this day. To be clear, severe iron overload still causes significant morbidity and mortality in many parts of the world, but current understanding of iron metabolism, non-invasive monitoring of organ specific iron loading in humans and effective iron chelators have dramatically reduced morbidity of iron overload. Furthermore, clinical experience in hemoglobinopathies supports iron biology learned from animal studies and identifies common concepts in the biology of iron toxicity that inform the management of iron toxicity in several human disorders.

Transfusional hemosiderosis in childhood cancer patients and survivors.

Background: Children treated for cancer are at risk for adverse effects of iron due to transfusions administered during prolonged marrow suppression, which may increase exposure to toxic forms of iron, extrahepatic iron accumulation, and long-term organ damage.

Objective: This study aimed to characterize the severity and organ distribution of clinically significant, multisystem iron overload (IO) in an at-risk cohort of pediatric cancer patients.

Methods: This was a retrospective, cross-sectional study of childhood cancer patients who underwent a magnetic resonance imaging (MRI) due to clinical concern for IO.

Significant pituitary siderosis is common in transfusion-dependent sickle cell disease.

Chronically transfused patients with sickle cell disease typically do not exhibit iron-mediated extrahepatic toxicity. However, we demonstrate that the pituitary gland is vulnerable to iron deposition, and it occurs regardless of other extrahepatic involvement. Severe pituitary siderosis is associated with early organ dysfunction.

Implementing a male-specific ART counselling curriculum: a quality assessment with healthcare workers in Malawi.

Introduction: There is little HIV counselling that directly meets the needs of men in Eastern and Southern Africa, limiting men's knowledge about the benefits of HIV treatment and how to overcome barriers to engagement, contributing to poorer HIV-related outcomes than women. Male-specific approaches are needed to improve men's outcomes but may be difficult for healthcare workers (HCWs) to implement with fidelity and quality in low-resource settings. We developed a male-specific counselling curriculum which was implemented by male HCWs and then conducted a mixed-methods quality assessment.

Systematic review and evidence gap assessment of the clinical, quality of life, and economic burden of alpha-thalassemia.

A recent evidence gaps assessment of the clinical, health-related quality of life, and economic burden associated with α-thalassemia is lacking. We conducted a systematic literature review (SLR) following the methodological and reporting requirements of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses and the Cochrane Handbook for Systematic Reviews, using available literature over the past decade. This SLR identified a considerable evidence gap with regard to understanding the current burden of α-thalassemia as evident from paucity of studies published in the past 10 years.

A germline variant preceding development of concurrent T-lymphoblastic leukemia and myelodysplastic syndrome.

Germline variants of the RUNX1 gene are associated with RUNX1 Familial Platelet Disorder with Associated Myeloid Malignancies (RUNX1-FPDMM), which is characterized by an increased risk of developing myelodysplastic syndrome (MDS) and/or acute myeloid leukemia. Patients with FPDMM have also been described to develop B- or T-cell acute lymphoblastic leukemia. We present a pediatric patient with RUNX1-FPDMM that evolved into concurrent MDS and T-cell acute lymphoblastic leukemia after a decade of monitoring with serial blood counts.

Black Sexual Minority Men's Experiences in MPowerment Interventions: Implications for HIV Prevention.

Background: Black sexual minority men (BSMM) are disproportionately vulnerable to HIV acquisition; the MPowerment model is one community-based framework for preventing HIV in this population. It focuses on developing a supportive network of peers to promote health messaging, reduce stigma, and improve resilience. While these interventions have demonstrated general success, there are important challenges related to race, sexuality, and internalized stigma.

Mammal responses to global changes in human activity vary by trophic group and landscape.

Wildlife must adapt to human presence to survive in the Anthropocene, so it is critical to understand species responses to humans in different contexts. We used camera trapping as a lens to view mammal responses to changes in human activity during the COVID-19 pandemic. Across 163 species sampled in 102 projects around the world, changes in the amount and timing of animal activity varied widely.

Αlpha-thalassemia: A practical overview.

α-Thalassemia is an inherited blood disorder characterized by decreased synthesis of α-globin chains that results in an imbalance of α and β globin and thus varying degrees of ineffective erythropoiesis, decreased red blood cell (RBC) survival, chronic hemolytic anemia, and subsequent comorbidities. Clinical presentation varies depending on the genotype, ranging from a silent or mild carrier state to severe, transfusion-dependent or lethal disease. Management of patients with α-thalassemia is primarily supportive, addressing either symptoms (eg, RBC transfusions for anemia), complications of the disease, or its transfusion-dependence (eg, chelation therapy for iron overload).

Decreased erythrocyte aggregation in Glenn and Fontan: univentricular circulation as a rheologic disease model.

Background: In the Fontan palliation for single ventricle heart disease (SVHD), pulmonary blood flow is non-pulsatile/passive, low velocity, and low shear, making viscous power loss a critical determinant of cardiac output. The rheologic properties of blood in SVHD patients are essential for understanding and modulating their limited cardiac output and they have not been systematically studied. We hypothesize that viscosity is decreased in single ventricle circulation.

Integration of HIV pre-exposure prophylaxis (PrEP) services for pregnant and breastfeeding women in eight primary care clinics: results of an implementation science study.

Background: Although HIV vertical transmission (VT) has declined significantly in sub-Saharan Africa, incident HIV infection in pregnant and postpartum women is estimated to account for roughly one-third of VT. Oral pre-exposure prophylaxis (PrEP) for pregnant and breastfeeding women (PBFW) is part of the recommended guidelines in South Africa since 2021; however, integration of PrEP services within antenatal (ANC) and postnatal care (PNC) remains limited.

Methods: Between March 2022 and September 2023, we evaluated the acceptability, feasibility and sustainability of integrating PrEP for PBFW in high-HIV prevalence clinics after training and mentoring health care providers (HCP).

McDAPS: A multi-channel physiological signals display and analysis system for clinical researchers.

We introduce McDAPS, an interactive software for assessing autonomic imbalance from non-invasive multi-channel physiological recordings. McDAPS provides a graphical user interface for data visualization, beat-to-beat processing and interactive analyses. The software extracts beat-to-beat RR interval systolic blood pressure, diastolic blood pressure, the pulse amplitude of photoplethysmogram and the pulse-to-pulse interval.

Health care workers' perceptions and bias toward men as HIV clients in Malawi and Mozambique: A qualitative study.

Men are underrepresented in HIV services throughout sub-Saharan Africa. Little is known about health care worker (HCW) perceptions of men as clients, which may directly affect the quality of care provided, and HCWs' buy-in for male-specific interventions. Focus group discussions (FGDs) were conducted in 2016 with HCWs from 15 facilities across Malawi and Mozambique and were originally conducted to evaluate barriers to universal treatment (not HCW bias).

Functional near-infrared spectroscopy-based prefrontal cortex oxygenation during working memory tasks in sickle cell disease.

Significance: Sickle cell disease (SCD), characterized by painful vaso-occlusive crises, is associated with cognitive decline. However, objective quantification of cognitive decline in SCD remains a challenge, and the associated hemodynamics are unknown.

Aim: To address this, we utilized functional near-infrared spectroscopy (fNIRS) to measure prefrontal cortex (PFC) oxygenation responses to -back working memory tasks in SCD patients and compared them with healthy controls.

Evaluating the use of oral pre-exposure prophylaxis among pregnant and postpartum adolescent girls and young women in Cape Town, South Africa.

Background: Adolescent girls and young women (AGYW) in South Africa are at a higher risk of acquiring HIV. Despite the increasing availability of daily oral pre-exposure prophylaxis (PrEP) for HIV prevention, knowledge on PrEP use during pregnancy and postpartum periods at antenatal care (ANC) facilities remains inadequate.

Methods: Data from HIV-uninfected pregnant women in Cape Town, South Africa, were used in this study.

COVID-19, Vaccine Hesitancy, and HIV Pre-exposure Prophylaxis Among Black Sexual Minority Men.

Background: The COVID-19 pandemic has created substantial and profound barriers to several forms of health care engagement. For Black sexual minority men, this may include engagement with pre-exposure prophylaxis (PrEP) to prevent HIV infection, with significant implications for HIV disparities. Our study explored how the COVID-19 pandemic affected Black sexual minority men, with a focus on relationships between COVID-19 and PrEP engagement.
