African Medicinal Plants in Cutaneous Wound Repair: A Comprehensive Analysis of the Role of Phytochemicals

ABSTRACT

Chronic and non-healing wounds are a global health issue with limited effective treatments. Wound care costs continue to rise, highlighting the need for new therapies. Medicinal plants, particularly African species, show promise for enhancing wound healing. This review analysed 93 studies and identified 37 relevant to wound healing, covering 39 plant species. Ten species were identified for their rich phytochemical content, specifically flavonoids, terpenoids, and alkaloids (plant-derived compounds). These compounds act synergistically, enhancing the wound healing process at each stage. Flavonoids reduce inflammation and support tissue turnover, while terpenoids enhance collagen production and wound closure. Alkaloids offer antimicrobial benefits and support wound contraction. Notable plants include Ageratum conyzoides and Aspilia africana (Asteraceae family); promoting haemostasis by lowering plasma fibrinogen and enhancing platelet-derived growth factors; Withania somnifera (Solanaceae); and Entada africana (Fabaceae), effectively regulating inflammation. In the proliferative phase, Ocimum gratissimum (Lamiaceae), Calendula officinalis (Asteraceae), and Centella asiatica (Apiaceae) although C. officinalis is native to Southern Europe, and C. asiatica an Asian-native; they are widely used in African traditional medicine and included here for their relevance in African wound healing practices; Justicia flava (Acanthaceae), Alternanthera sessilis (Amaranthaceae), and Acalypha indica (Euphorbiaceae); play key roles in enhancing collagen production, angiogenesis, and re-epithelialisation. This comprehensive analysis highlights the role of African medicinal plants in wound healing and their potential to improve wound care therapy.

Assessment of change and persistence of youth psychosocial status reported by youth and their guardians during the COVID-19 pandemic: A MyHEARTSMAP study

by Melissa L. Woodward, Morgan W. Wolsey, Sophia Shalchy-Tabrizi, Jeffrey N. Bone, Tyler Black, Quynh Doan

Background

The pediatric mental health crisis pre-dated the COVID 19 pandemic with rates of mental health visits to pediatric emergency departments steadily increasing for the last decade. The COVID-19 pandemic has profoundly impacted children and adolescents and understanding the trajectory of their psychosocial status is important for appropriate resource allocation and policy planning.

Methods

MyHEARTSMAP is a digital self-assessment mental health evaluation that examines four major psychosocial domains: psychiatry, social, function, and youth health. Children and adolescents throughout British Columbia, and their guardians, completed the baseline assessment between August 2020 and July 2021 (51.8% completed by guardian only, 40.2% youth and guardians, 7.9% youth only). Both children and their guardians repeated the MyHEARTSMAP evaluation three-months after their baseline. Patient demographics and psychosocial concerns were statistically described and compared between baseline and follow-up. A logistic regression model assessed the influence of baseline scores and demographic factors on follow-up severity.

Results

241 of 424 participants (56.8%) completed both the baseline and three-month follow-up. The majority of participants reported no change overtime across the psychosocial domains. Both improvement and decline occurred in each domain, with a greater proportion of psychosocial states improving rather than worsening, for all domains. Higher severity of psychosocial concerns reported at baseline indicated a greater likelihood of psychosocial concerns at 3-month follow-up for psychiatric, social and function concerns. Demographic, pandemic, and support service variables were not associated with psychosocial trajectories.

Conclusions

The severity of youth mental health concerns in British Columbia remained consistent through three-month follow up, despite the changing nature of the COVID-19 pandemic during this period. Greater persistence of psychosocial concerns with increased severity highlights the need for early intervention to prevent worsening mental health. Community support is needed for youth experiencing mental health concerns to address mild psychosocial concerns before presentation at the emergency department.

Por: Kibone · W. · Muzoora · C. · Bongomin · F. · Namiiro · M. A. · Ssenkungu · S. · Ochola · E. · Kasirye · P. · Hamer · D. H.
Background

Sickle cell disease (SCD) is associated with significant mortality and morbidity, especially in low- and middle-income countries.

Objectives

We determined the indications for hospitalisation and predictors of 30-day re-admission among patients with SCD in Northern and Central Uganda.

Design

Retrospective chart review.

Setting

Mulago National Referral Hospital in Kampala, St. Mary’s Hospital Lacor in Gulu and Gulu Regional Referral Hospital in Gulu, Uganda.

Participants

Patients with confirmed SCD admitted between January 2020 and January 2025 were included.

Outcomes

Primary outcome: indication for hospitalisation. Secondary outcomes: rate and predictors of 30-day hospital re-admission. Socio-demographic, clinical history and hospitalisation data were extracted using a pretested data extraction tool.

Results

We enrolled 505 patients, accounting for 714 hospital admissions, with a mean age of 8.1±6.2 years. Most participants (n=489, 96.8%) had less than four admissions per year, with a median of 1 admission (IQR: 0–2). The most common indications for hospitalisation were infection (n=375, 52.5%), painful crisis (n=366, 51.3%) and anaemia (n=186, 26.1%). Malaria was the most prevalent infection (n=244, 65%). The median length of hospital stay was 4 days (IQR: 3–6), with a 30-day re-admission rate of 6.9% (n=49). Admission with painful crisis (adjusted OR (AOR): 0.45, 95% CI: 0.23 to 0.89, p=0.021), receiving a blood product (AOR: 0.32, 95% CI: 0.16 to 0.66, p=0.002) and having four or more admissions per year (AOR: 0.84, 95% CI: 0.04 to 0.17, p

Conclusions

Infections, especially malaria, and painful crises were the leading causes of hospitalisation among Ugandan patients with SCD. Frequent admissions, painful crises and blood transfusions were associated with lower 30-day re-admission risk. There is an urgent need to strengthen malaria prevention strategies and optimise access to disease-modifying therapy, such as hydroxyurea, to improve patient outcomes.

A whole new ball game: a retrospective cohort study using healthcare administrative data to uncover predictors of timely transition from paediatric to adult type 1 diabetes care in British Columbia, Canada

Por: Leung · J. M. W. S. · Chen · L. · Zhang · Q. · Bone · J. N. · Amed · S.
Objectives

To assess predictors of timely transition to adult diabetes care among individuals diagnosed with type 1 diabetes during childhood and adolescence. We hypothesised that older age at the last paediatric visit and urban residency would be predictors of timely transition.

Design

Retrospective cohort study using healthcare administrative data in a jurisdiction with a universal healthcare system.

Participants

2045 adolescents and young adults diagnosed with type 1 diabetes between the ages of 0.5 and 18 years.

Primary and secondary outcome measures

We ascertained age at the last paediatric diabetes visit (LPDV), age at the first adult diabetes visit (FADV) and transition duration, defined as the time between LPDV and FADV. Timely transition was defined as a transition duration of

Results

Only 31.3% of individuals saw an adult provider within 1 year of their LPDV. Each 1-year increase in the age at LPDV was associated with increased odds of timely transition (adjusted OR 1.82, 95% CI 1.71 to 1.93, p0.05).

Conclusions

Older age at the LPDV and urban residency are associated with increased odds of timely transition. Interventions should be developed to help keep adolescents engaged in paediatric care until an older age before referring them to adult diabetes care. Limitations of this study include unmeasured confounding and limited generalisability to non-universal healthcare systems.

Are client and provider preferences for HIV care coordination programme features concordant? Discrete choice experiments in Ryan White part A-funded New York City care coordination programmes

Por: Zimba · R. · Fong · C. · Conte · M. · Guarino · H. · Avoundjian · T. · Carmona · J. · Herndon · G. · Gambone · G. · Irvine · M. K. · Nash · D.
Objectives

The New York City (NYC) HIV Care Coordination Programme (CCP) is designed to help people with HIV (PWH) overcome barriers to care and treatment engagement. We assessed preferences for CCP components among programme enrollees (’clients’) and providers. Our objective is to compare client and provider preferences, which were previously analysed separately.

Design

We used a discrete choice experiment to assess preferences for four CCP features (‘attributes’): Help with Adherence to Antiretroviral Therapy (ART), Help with Primary Care Appointments, Help with Issues other than Primary Care and Where Programme Visits Happen. Each of these attributes had 3–4 variants (‘levels’). In the original surveys, levels within Where Programme Visits Happen varied by participant type (client vs provider). We recoded the levels by visit location (VL) or by travel time (TT) to make them comparable and report results from both approaches.

Setting

25 Ryan White Part A-funded NYC CCPs participated.

Participants

152 providers and 181 clients completed the survey.

Primary and secondary outcome measures

Preferences were quantified using the relative importance of the attributes and utility of the levels.

Results

From January 2020 to March 2021, 152 providers and 181 clients completed the survey. Most of the providers (52%) were

Conclusions

Client and provider preferences clearly diverged regarding CCP service intensity: in the aggregate, clients tended to prefer lower-intensity services, whereas providers endorsed higher-intensity services. These results highlight the importance of engaging clients as partners in decisions about programme services to facilitate alignment with client values.

How can community pharmacy teams prevent prescription and over-the-counter opioid misuse in North East England? A qualitative study using the Capability, Opportunity and Motivation Behaviour (COM-B) model

Por: Offu · O. F. · Okeowo · D. · Visram · S. · Rathbone · A. P. · Lindsey · L.
Aim

This study aims to identify factors that influence the role of community pharmacy teams in preventing prescription and over-the-counter (OTC) opioid misuse.

Design

Qualitative design using interviews; thematic analysis was used to generate themes mapped to the Capability, Opportunity and Motivation Behaviour (COM-B) model.

Setting

Community pharmacies in North East England.

Participants

28 community pharmacy staff including 16 pharmacists, 1 pharmacy assistant, 10 dispensers and 1 pharmacy technician.

Results

Factors related to the capability component include communication skills, ability to identify service users who misuse OTC opioids, and education and training. Factors in the opportunity component include staff and funding, tools for identification and referral of service users at risk of opioid misuse, and relationship with other healthcare professionals. For the motivation component, attitude towards role, attitude of pharmacist or pharmacy manager, perception about commissioners and commissioned services, and attitude towards service users were identified.

Conclusion

This study identified factors that could influence community pharmacists’ roles in opioid misuse. A critical factor influencing community pharmacy teams preventing opioid misuse is access to a single system to record the use of both OTC and prescription opioids. This would enable teams to identify service users misusing or at risk of misusing opioids, while supporting staff education and training and regulatory compliance. Future research should focus on developing interventions using these identified factors to enhance community pharmacists’ roles in opioid misuse prevention.

The histone deacetylase inhibitor CT-101 flips the switch to fetal hemoglobin expression in sickle cell disease mice

by Mayuko Takezaki, Biaoru Li, Hongyan Xu, Nikhil Patel, Rudolf Lucas, Ryan E. Cerbone, Sivanagireddy Koti, Clifford L. Hendrick, Louis H. Junker, Betty S. Pace

The most common hemoglobin disorder worldwide is sickle cell disease (SCD) caused by a point mutation in the adult β-globin gene. As a result, hemoglobin S production occurs leading to clinical symptoms including vaso-occlusive pain, organ damage, and a shortened lifespan. Hydroxyurea is the only FDA-approved fetal hemoglobin (HbF) inducer in the United States that ameliorates the clinical severity of SCD. Due to challenges with hydroxyurea, our study aimed to address the unmet need for the development of non-chemotherapeutic HbF inducers. We investigated the ability of CT-101, a Class 1 histone deacetylase inhibitor, to flip the γ-globin to β-globin switch in a humanized SCD mouse model. Pharmacokinetic parameters were assessed in CD-1 and Townes SCD mice after a single intraperitoneal drug dose. Similar drug uptake and half-life were observed in both animals. Subsequent studies in β-YAC mice expressing human γ-globin and β-globin genes established the optimal dose of CT-101 that induces HbF without peripheral blood toxicity. Subsequent confirmatory studies were conducted in the SCD mouse treated with intraperitoneal CT-101, demonstrating increases in F-cells, HbF, and γ-globin gene mRNA levels. Hydroxyurea combined with CT-101 significantly decreased spleen size and hemorrhagic infarcts and improved splenic extramedullary hematopoiesis. Our novel agent, CT-101, flipped the switch by activating γ-globin gene transcription and HbF protein synthesis in the preclinical SCD mouse model without significant toxicity in the peripheral blood. These findings support the development of an oral CT-101 formulation for clinical testing in SCD.

Molecular characterization of chronic cutaneous wounds reveals subregion‐ and wound type‐specific differential gene expression

Abstract

A limited understanding of the pathology underlying chronic wounds has hindered the development of effective diagnostic markers and pharmaceutical interventions. This study aimed to elucidate the molecular composition of various common chronic ulcer types to facilitate drug discovery strategies. We conducted a comprehensive analysis of leg ulcers (LUs), encompassing venous and arterial ulcers, foot ulcers (FUs), pressure ulcers (PUs), and compared them with surgical wound healing complications (WHCs). To explore the pathophysiological mechanisms and identify similarities or differences within wounds, we dissected wounds into distinct subregions, including the wound bed, border, and peri-wound areas, and compared them against intact skin. By correlating histopathology, RNA sequencing (RNA-Seq), and immunohistochemistry (IHC), we identified unique genes, pathways, and cell type abundance patterns in each wound type and subregion. These correlations aim to aid clinicians in selecting targeted treatment options and informing the design of future preclinical and clinical studies in wound healing. Notably, specific genes, such as PITX1 and UPP1, exhibited exclusive upregulation in LUs and FUs, potentially offering significant benefits to specialists in limb preservation and clinical treatment decisions. In contrast, comparisons between different wound subregions, regardless of wound type, revealed distinct expression profiles. The pleiotropic chemokine-like ligand GPR15L (C10orf99) and transmembrane serine proteases TMPRSS11A/D were significantly upregulated in wound border subregions. Interestingly, WHCs exhibited a nearly identical transcriptome to PUs, indicating clinical relevance. Histological examination revealed blood vessel occlusions with impaired angiogenesis in chronic wounds, alongside elevated expression of genes and immunoreactive markers related to blood vessel and lymphatic epithelial cells in wound bed subregions. Additionally, inflammatory and epithelial markers indicated heightened inflammatory responses in wound bed and border subregions and reduced wound bed epithelialization. In summary, chronic wounds from diverse anatomical sites share common aspects of wound pathophysiology but also exhibit distinct molecular differences. These unique molecular characteristics present promising opportunities for drug discovery and treatment, particularly for patients suffering from chronic wounds. The identified diagnostic markers hold the potential to enhance preclinical and clinical trials in the field of wound healing.

Tratamiento antibiótico en la etapa perinatal y mastitis en la madre lactante: una asociación posible

Objetivo: El objetivo del estudio fue identificar algunos posibles factores causantes de mastitis en mujeres lactantes. Metodología: Estudio de casos y controles; 55 casos (mujeres lactantes con dolor en el pecho, y/o sintomatología de mastitis y cultivo positivo) y 54 controles (mujeres lactantes sin dolor ni sintomatología de mastitis). Se recopiló información retrospectiva sobre diversos factores de riesgo. Se realizó análisis multivariante de las variables significativas. Resultados principales: factores asociados significativamente con mastitis: tratamiento materno con antibióticos en el período perinatal (ORa = 3,935 IC =1,15 – 6,13) suplementos de hierro (ORa = 0,241; IC= 0,092 - 0,631) y anestesia epidural (ORa = 0,196; IC= 0,066 – 0,693).  Conclusión principal: La antibioterapia durante el periodo perinatal podría estar relacionada con el desarrollo de mastitis durante la lactancia. En cambio los suplementos de hierro suponían un factor de protección. Es importante seguir investigando para prevenir posibles mastitis en madres lactantes que hayan recibido antibiótico y que valoren el significado de los suplementos de hierro.
