Circulating natural killer cells and their association with breast cancer and its clinico-pathological characteristics. Ecancermedicalscience 2023; 17:1567. [PMID: 37533944 PMCID: PMC10393315 DOI: 10.3332/ecancer.2023.1567] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2023] [Indexed: 08/04/2023] Open
Abstract
Purpose Natural killer (NK) cells play a critical role in cancer immunosurveillance and hold promise as both therapies and prognostic markers in advanced disease. We explore factors that may influence NK cell concentration in the peripheral blood of women with breast cancer in Côte d'Ivoire compared to healthy controls and implications for future research in our context. Methods In this cross-sectional case-control study, blood samples were taken from 30 women diagnosed with breast cancer within 6 months of diagnosis and fifteen healthy women at University Teaching Hospital [Centre Hospitalier Universitaire (CHU)] Treichville in Abidjan, Côte d'Ivoire, from March to September 2018. The blood draw could take place at any time following diagnosis and through treatment. Demographic and clinical data were collected. NK cells were isolated, stained, analysed and counted using the flow cytometer at the Department of Immunology at CHU of Cocody. All p-values were two-sided. Results Mean age among 30 women with breast cancer was 49 years old compared to 45 years old for 15 controls (p = 0.41). Among 30 women with breast cancer, 4 (13.3%) had Stage 2 disease, 14 (46.7 %) at Stage 3, and 12 (40%) at Stage 4. Fourteen (46.7%) had breast cancer that was hormone receptor-positive (HR+) HER2-negative, 10 (33.3%) had triple-negative cancer, three (10.0%) had HR+HER2+ disease, and three (10.0%) HR-HER2+ cancer. NK cell concentration was not associated with cancer diagnosis, age, cancer stage, subtype, or type of treatment patients received (p > 0.05). Conclusion Although we did not find an association between NK cell concentration, cancer characteristics or treatment, our results be limited by the small sample size and timing of blood draw. Our next steps include a larger study to explore circulating NK cells prior to any treatment and NK cell infiltration within breast cancer tumour and correlating this with response to treatment and prognosis.

Digital Health Technologies Applied by the Pharmaceutical Industry to Improve Access to Noncommunicable Disease Care in Low- and Middle-Income Countries. GLOBAL HEALTH, SCIENCE AND PRACTICE 2022; 10:e2200072. [PMID: 36316151 PMCID: PMC9622287 DOI: 10.9745/ghsp-d-22-00072] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 02/22/2022] [Accepted: 08/23/2022] [Indexed: 06/16/2023]
Abstract
BACKGROUND There is limited research on how digital health technologies (DHTs) are used to promote access to care for patients with noncommunicable diseases (NCDs), particularly in low- and middle-income countries (LMICs). We describe the use of DHTs in pharmaceutical industry-led access programs aimed at improving access to NCD care in LMICs. METHODS The Access Observatory is the largest publicly available repository containing detailed information about pharmaceutical industry-led access programs targeting NCDs. The repository includes 101 access program reports submitted by 19 pharmaceutical companies. From each report, we extracted data relating to geographic location, disease area, beneficiary population, use of DHTs, partnerships, strategies, and activities. Data were analyzed descriptively using SAS Statistical Software and categorized according to the World Health Organization Digital Health Classification Framework. RESULTS A total of 43 access programs (42.6%) included DHTs. The majority of programs using DHTs were clustered across sub-Saharan Africa (72.1%) and targeted cancer (60.5%) followed by metabolic disorders (39.5%). The applied DHTs mostly related to program strategies on health service strengthening (74.4%) and community awareness (41.9%) and were largely directed toward health providers, followed by data services and clients. Only a few DHTs were used for health system management. To promote access, most DHTs focused on improving data collection, management, and use (51.1%); building health provider capacity through training (37.2%); and providing targeted patient information (34.8%). CONCLUSION The range of DHTs applied by the pharmaceutical industry offers opportunities for more effective access to NCD care. Transparent reporting on DHT use and its contributions to access programs' achievements may reduce duplicative and redundant efforts and provide learnings for private and public stakeholders that may contribute to greater access to NCD care in LMICs.

Abstract
Pharmaceutical industry-led access programs are growing in number globally and are increasingly adopting a hybrid approach intended to generate commercial and social value in parallel. We developed and applied a new conceptual framework in a descriptive analysis of observable indicators measuring commercial and social value for 91 programs registered in the Access Observatory. We found that most programs had features consistent with the generation of commercial value, directly through revenue generation (50.0%), or indirectly by creating competitive advantage (70.3%). We also found that most programs were implemented in countries where the company has commercial products registered (85.5%). While many programs had features consistent with the generation of social value, it was difficult to ascertain the level of that value because most did not share data (83.5%) and had not been evaluated (74.7%). Future efforts by the global health community and the pharmaceutical industry should focus on strengthening measurement and reporting on commercial and social indicators of industry-led access programs.

Abstract
BACKGROUND In low- and middle-income countries (LMICs), multinational companies have become increasingly involved in addressing public health challenges. Dealing with companies as partners in health sector development creates new challenges for governments. We sought to develop an approach to assess the existence and effectiveness of governance structures that can ensure that industry-led public health initiatives contribute to development. METHODS We developed a governance assessment tool based on the principles of the Paris Declaration for Aid Effectiveness and other related agreements. We applied it to the case of pharmaceutical companies' involvement in the Kenyan response to non-communicable diseases (NCDs). We gathered data for analysis through 46 stakeholder interviews and reviewing documents. RESULTS The Kenyan government has informal norms in place regarding program governance and strategy, but it has yet to issue formal regulations. While enabling elements exist that support initiatives to develop in alignment with these norms, implementation is often hindered by a lack of resources. Currently, broad stakeholder support for filling these gaps has created a window of opportunity for action. CONCLUSION The application of the proposed assessment tool illustrates its viability for assisting companies and governments alike in defining governance needs for industry-led public health initiatives. Our findings in Kenya provide example considerations for LMICs working to integrate industry-led public health programs into the health system. Bilateral and multilateral donors also have important roles in strengthening LMICs' capacities to govern multinational corporations' contributions to NCDs in particular, and development in general.
