Anaba EA, Alor SK, Badzi CD, Mbuwir CB, Muki B, Afaya A. Drivers of breast cancer and cervical cancer screening among women of reproductive age: insights from the Ghana Demographic and Health Survey. BMC Cancer 2024; 24:920. [PMID: 39080553 PMCID: PMC11290011 DOI: 10.1186/s12885-024-12697-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2024] [Accepted: 07/25/2024] [Indexed: 08/02/2024] Open
Abstract
BACKGROUND The two major causes of cancer-related deaths among women in Ghana are breast cancer (BC) and cervical cancer (CC). These types of cancers typically do not show any symptoms until they have progressed. Therefore, it is important to screen for early detection. This research aimed to investigate the rate of breast cancer and cervical cancer screening, as well as the factors associated with it, among women of reproductive age in Ghana. METHODS This study analysed data from the 2022 Ghana Demographic and Health Survey. A total of 15,014 women aged 15 to 49 years were included in the analysis. Descriptive statistics and binary logistic regression were employed to analyse the data with the aid of STATA/SE, version 17. RESULTS It was found that 18.4% and 5.0% of the women had screened for BC and CC, respectively. Women aged 45-49 years were about three times more likely (aOR = 2.83, 95% CI: 1.88-4.24) to screen for BC compared to those aged 15-19 years. Women who had tested for HIV had increased odds (aOR = 1.88, 95% CI: 1.56-2.25) of screening for BC compared to their counterparts. Women within the richest wealth index (aOR = 1.95, 95% CI: 1.40-2.72) had increased odds of screening for BC compared to those in the poorest wealth index. Regarding CC screening, women with higher education (aOR = 2.56, 95% CI: 1.53-4.29) were two times more likely to screen for CC compared to those with no formal education. Women who did not use tobacco (aOR = 0.45, 95% CI: 0.21-0.96) had decreased odds of CC screening compared to their counterparts. CONCLUSIONS This study showed that the uptake of BC and CC screening services among women in Ghana was very low. The drivers of BC and CC screening included enabling, predisposing, and need factors. Stakeholders can leverage the mass media to raise awareness and educate women in reproductive age about the importance of BC and CC screening. This study provides relevant information that can inform BC and CC policies and programmes in Ghana.

Palliat Care Soc Pract 2024; 18:26323524241262327. [PMID: 38911601 PMCID: PMC11191610 DOI: 10.1177/26323524241262327] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2024] [Accepted: 05/30/2024] [Indexed: 06/25/2024] Open
Abstract
Background The growing burden of life-threatening illnesses and advancements in care interventions call for the intentional integration of palliative care services into existing care systems. The absence of active, functioning palliative care services in most hospitals in Ghana is a major concern. This study explored the factors influencing the integration of palliative care services in one of such institutions. Objectives The aim of the study was to explore the institutional drivers of palliative care integration in a military health facility. Design Exploratory qualitative study. Methods We employed a qualitative exploratory study design situated within a constructivist paradigm. A purposive sampling method was used to select and interview 11 healthcare professionals. A semistructured interview was used to conduct face-to-face, in-depth interviews with participants between April and May 2022. A thematic data analysis was done based on the Braun and Clarke analysis process with the aid of QSR NVivo-12. Results The six themes that describe the institutional driving factors for integrating palliative care services were cognitive restructuring, supportive logistics and infrastructure, staffing, healthcare professional skills, institutional policies and priorities, and utilization of focal persons. It was observed that a paradigm shift in the mindset of healthcare professionals and administrators was a major driver that would determine the integration of palliative care services. A cognitive restructuring will facilitate a more aggressive integration of palliative care services because logistics, staffing, and medication access will be prioritized. Conclusion Institutions have the responsibility of aligning with the WHO policy on palliative care service access and must invest in training, staffing, prioritizing palliative care needs and policies, procurement of essential drugs, and the provision of logistics and supportive infrastructure to scale up the implementation of palliative care services.

Impact of cancer diagnosis and treatment: a qualitative analysis of strains, resources and coping strategies among elderly patients in a rural setting in Ghana. BMC Geriatr 2023; 23:540. [PMID: 37670259 PMCID: PMC10481500 DOI: 10.1186/s12877-023-04248-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2022] [Accepted: 08/21/2023] [Indexed: 09/07/2023] Open
Abstract
BACKGROUND Rurality is fraught with numerous difficulties including a lack of advanced health facilities to provide health services, and an absence of specialist cancer services, and qualified personnel, among others. These factors exacerbate the challenges of elderly patients diagnosed with cancer and further pose limitations to activities/instrumental activities of daily living. Yet, there is limited scholarship on the strains that affect elderly patients diagnosed with cancer and the resources that helps them to overcome them. This study explores the strains, resources, and coping strategies of elderly patients diagnosed with cancer and undergoing treatment in rural Ghana. METHODS An exploratory, descriptive qualitative design was adopted. Purposive sampling was used to recruit 20 individuals to participate in in-depth interviews. The collected data was analysed inductively using Collaizi's framework. QSR NVivo-12 was used in managing the data. RESULTS The results were grouped into two main categories, namely: strains and resources. Within the category of strains, three main themes with their corresponding sub-themes emerged: cancer-related strains (systemic side effects from treatment, altered physical appearance and body image, and experience of pain), elderly strains (altered functional ability, limited social interactions and participation, psycho-emotional reactions, limited/restricted economic participation, and financial strains), and health system strains (negative attitude and insensitive communication, delay in diagnosis, lack of geriatric oncology care, lack of community-based specialist cancer centre and long travel distance to access care, and limited availability of essential cancer medicines and other radiations services). Four types of resources were available to cancer patients: personal resources, family resources, community resources, and healthcare systems resources. CONCLUSION In conclusion, elderly patients diagnosed with cancer experience physical, economic, psychological, and emotional strains that threaten their health and well-being. However, they are able to leverage family, community, and health system-related resources to navigate through the strains. There is, therefore, a need to expand advanced health facilities with geriatric oncology units and specialists to improve access to cancer care in rural areas. The government needs to assist elderly persons with costs associated with their diagnosis and treatment through the expansion of the National Health Insurance Scheme to include this as part of the benefits package.

Abstract
Cancer incidence is increasing worldwide and is a major cause of mortality. The relative magnitude of the increase is remarkably high in low human development index (HDI; 95%) and medium HDI (64%) countries. On the African continent, a corresponding increase in cancer burden is predicted, particularly for sub-Saharan Africa. Current epidemiologic data indicate that mortality rates of certain cancers, such as breast and cervical cancers, in sub-Saharan Africa are the highest in the world, and the cancer risks are broadly comparable to the risks in high-income countries, such as the United States and Europe. Although emerging data alludes to the unique genetic profile of cancer in African populations, most cancer therapies are introduced to Africa without confirmatory clinical trials. Therefore, there is an increasing need for clinical trials directed toward prevention, screening, diagnosis, and identification of innovative treatments in the African context. This review will discuss the increasing cancer burden in Africa, with a particular focus on Ghana, unmet clinical needs in cancer, current medical systems, clinical trial regulatory systems, and challenges to clinical trial recruitment.

[PMID: 35621929 PMCID: PMC9146362 DOI: 10.3390/md20050278] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2022] [Revised: 04/18/2022] [Accepted: 04/19/2022] [Indexed: 01/16/2023] Open
Abstract
In this study, chitosan nanoparticles (HF-CD NPs) were synthesized by an ionic gelation method using negatively charged carboxymethyl-β-cyclodextrin and positively charged 2-hydroxypropyltrimethyl ammonium chloride chitosan bearing folic acid. The surface morphology of HF-CD NPs was spherical or oval, and they possessed relatively small particle size (192 ± 8 nm) and positive zeta potential (+20 ± 2 mV). Meanwhile, doxorubicin (Dox) was selected as model drug to investigate the prepared nanoparticles’ potential to serve as a drug delivery carrier. The drug loading efficiency of drug-loaded nanoparticles (HF-Dox-CD NPs) was 31.25%. In vitro release profiles showed that Dox release of nanoparticles represented a pH-sensitive sustained and controlled release characteristic. At the same time, the antioxidant activity of nanoparticles was measured, and chitosan nanoparticles possessed good antioxidant activity and could inhibit the lipid peroxidation inside the cell and avoid material infection. Notably, CCK-8 assay testified that the nanoparticles were safe drug carriers and significantly enhanced the antitumor activity of Dox. The nanoparticles possessed good antioxidant activity, pH-sensitive sustained controlled release, enhanced antitumor activity, and could be expected to serve as a drug carrier in future with broad application prospects.

[PMID: 35443647 PMCID: PMC9022278 DOI: 10.1186/s12913-022-07775-z] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2021] [Accepted: 03/14/2022] [Indexed: 12/24/2022] Open
Abstract
INTRODUCTION Female breast cancer is currently the most commonly diagnosed cancer globally with an estimated 2.3 million new cases in 2020. Due to its rising frequency and high mortality rate in both high- and low-income countries, breast cancer has become a global public health issue. This review sought to map literature to present evidence on knowledge of breast cancer screening and its uptake among women in Ghana. METHODS Five databases (PubMed, CINAHL, PsycINFO, Web of Science, and EMBASE) were searched to identify relevant published studies between January 2012 and August 2021 on knowledge of breast cancer screening and its uptake among women. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) extension for scoping reviews and the six-stage model by Arksey and O'Malley were used to select and report findings. RESULTS Of the 65 articles retrieved, 14 records were included for synthesis. The review revealed varied knowledge levels and practices of breast cancer screening among women across a few regions in Ghana. The knowledge level of women on breast cancer screening was high, especially in breast cancer screening practice. Breast cancer screening practice among women was observed to be low and the most identified barriers were lack of technique to practice breast self-examination, having no breast problem, lack of awareness of breast cancer screening, and not having breast cancer risk. The results further showed that good knowledge of breast cancer screening, higher educational level, increasing age, physician recommendation, and household monthly income were enabling factors for breast cancer screening uptake. CONCLUSION This review showed varied discrepancies in breast cancer screening uptake across the regions in Ghana. Despite the benefits of breast cancer screening, the utilization of the screening methods across the regions is very low due to some varied barriers from the different regions. To increase the uptake of breast cancer screening, health workers could employ various strategies such as community education and sensitization on the importance of breast cancer screening.

Abstract
In this paper, adriamycin-incorporated chitosan nanoparticles were synthesized by ionic gelation using negatively charged carboxymethyl chitosan and positively charged 2-hydroxypropyltrimethyl ammonium chloride chitosan. The method was efficient to obtain nanoparticles with low polydispersity index and small hydrodynamic diameter. And high zeta potential value indicated that nanoparticles had good stability. The adriamycin release of nanoparticles represented a significant response to pH, with the fastest release in phosphate buffer solution at pH 6.8. Meanwhile, the antioxidant efficiency of nanoparticles was assayed, and nanoparticles represented significant enhancement in radicals scavenging activity. The assay of cell viability by CCK-8 test exhibited that nanoparticles led to statistically significant decrease in cell viability for four kinds of cancer cells (HEPG-2, A549, MCF-7, and BGC-823). It was indicated that the nanoparticles with enhanced biological activity, reduced cytotoxicity, and pH-sensitive release could be served as potential drug carrier in drug delivery system.

A Robust and Highly Precise Alternative against the Proliferation of Intestinal Carcinoma and Human Hepatocellular Carcinoma Cells Based on Lanthanum Strontium Manganite Nanoparticles. MATERIALS 2021; 14:ma14174979. [PMID: 34501078 PMCID: PMC8433762 DOI: 10.3390/ma14174979] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/12/2021] [Revised: 08/16/2021] [Accepted: 08/25/2021] [Indexed: 01/09/2023]
Abstract
In this report, lanthanum strontium manganite at different Sr2+ ion concentrations, as well as Gd3+ or Sm3+ ion substituted La0.5-YMYSr0.5MnO3 (M = Gd and Sm, y = 0.2), have been purposefully tailored using a sol gel auto-combustion approach. XRD profiles confirmed the formation of a monoclinic perovskite phase. FE-SEM analysis displayed a spherical-like structure of the La0.8Sr0.2MnO3 and La0.3Gd0.2Sr0.2MnO3 samples. The particle size of the LSM samples was found to decrease with increased Sr2+ ion concentration. For the first time, different LSM concentrations were inspected for their cytotoxic activity against CACO-2 (intestinal carcinoma cells) and HepG-2 (human hepatocellular carcinoma cells). The cell viability for CACO-2 and HepG-2 was assayed and seen to decrease depending on the Sr2+ ion concentration. Half maximal inhibitory concentration IC50 of CACO-2 cell and HepG-2 cell inhibition was connected with Sr2+ ion ratio. Low IC50 was noticable at low Sr2+ ion content. Such results were correlated to the particle size and the morphology. Indeed, the IC50 of CACO-2 cell inhibition by LSM at a strontium content of 0.2 was 5.63 ± 0.42 µg/mL, and the value increased with increased Sr2+ ion concentration by up to 0.8 to be = 25 ± 2.7 µg/mL. Meanwhile, the IC50 of HepG-2 cell inhibition by LSM at a strontium content of 0.2 was 6.73 ± 0.4 µg/mL, and the value increased with increased Sr2+ ion concentration by up to 0.8 to be 31± 3.1 µg/mL. All LSM samples at different conditions were tested as antimicrobial agents towards fungi, Gram positive bacteria, and Gram negative bacteria. For instance, all LSM samples were found to be active towards Gram negative bacteria Escherichia coli, whereas some samples have presumed antimicrobial effect towards Gram negative bacteria Proteus vulgaris. Such results confirmed that LSM samples possessed cytotoxicity against CACO-2 and HepG-2 cells, and they could be considered to play a substantial role in pharmaceutical and therapeutic applications.

Synthesis, Characterization, and Evaluation of Nanoparticles Loading Adriamycin Based on 2-Hydroxypropyltrimethyl Ammonium Chloride Chitosan Grafting Folic Acid. Polymers (Basel) 2021; 13:polym13142229.

Abstract
Chitosan nanoparticles have been considered as potential candidates for drug loading/release in drug delivery systems. In this paper, nanoparticles (HACAFNP) loading adriamycin based on 2-hydroxypropyltrimethyl ammonium chloride chitosan grafting folic acid (HACF) were synthesized. The surface morphology of the novel nanoparticles was spherical or oval, and the nanoparticles exhibited a relatively small hydrodynamic diameter (85.6 ± 2.04 nm) and positive zeta potential (+21.06 ± 0.96 mV). The drug release of nanoparticles was assayed and represented a burst effect followed by a long-term steady release. Afterward, the antioxidant efficiencies of nanoparticles were assayed. In particular, the target nanoparticles exhibited significant enhancement in radical scavenging activities. Cytotoxicities against cancer cells (MCF-7, BGC-823, and HEPG-2) were estimated in vitro, and results showed nanoparticles inhibited the growth of cancer cells. It's worth noting that the inhibition index of HACAFNP against BGC-823 cells was 71.19% with the sample concentration of 25 μg/mL, which was much higher than the inhibitory effect of ADM. It was demonstrated that the novel nanoparticles with dramatically enhanced biological activity, reduced cytotoxicity, and steady release could be used as the practical candidates for drug loading/release in a delivery system.
