RESUMO
We recently showed that riboflavin is a selected substrate of breast cancer resistance protein (BCRP) over P-glycoprotein (P-gp) and demonstrated its prediction performance in preclinical drug-drug interaction (DDI) studies. The aim of this study was to investigate the suitability of riboflavin to assess BCRP inhibition in humans. First, we assessed the substrate potential of riboflavin toward other major drug transporters using established transfected cell systems. Riboflavin is a substrate for organic anion transporter (OAT)1, OAT3, and multidrug and toxin extrusion protein (MATE)2-K, with uptake ratios ranging from 2.69 to 11.6, but riboflavin is not a substrate of organic anion-transporting polypeptide (OATP)1B1, OATP1B3, organic cation transporter (OCT)2, and MATE1. The effects of BMS-986371, a potent in vitro inhibitor of BCRP (IC 50 0.40 µM), on the pharmacokinetics of riboflavin, isobutyryl carnitine, and arginine were then examined in healthy male adults (N = 14 or 16) after oral administration of methotrexate (MTX) (7.5 mg) and enteric-coated (EC) sulfasalazine (SSZ) (1000 mg) alone or in combination with BMS-986371 (150 mg). Oral administration of BMS-986371 increased the area under the plasma concentration-time curves (AUCs) of rosuvastatin and immediate-release (IR) SSZ to 1.38- and 1.51-fold, respectively, and significantly increased AUC(0-4h), AUC(0-24h), and C max of riboflavin by 1.25-, 1.14-, and 1.11-fold (P-values of 0.003, 0.009, and 0.025, respectively) compared with the MTX/SSZ EC alone group. In contrast, BMS-986371 did not significantly influence the AUC(0-24h) and C max values of isobutyryl carnitine and arginine (0.96- to 1.07-fold, respectively; P > 0.05). Overall, these data indicate that plasma riboflavin is a promising biomarker of BCRP that may offer a possibility to assess drug candidate as a BCRP modulator in early drug development. SIGNIFICANCE STATEMENT: Endogenous compounds that serve as biomarkers for clinical inhibition of breast cancer resistance protein (BCRP) are not currently available. This study provides the initial evidence that riboflavin is a promising BCRP biomarker in humans. For the first time, the value of leveraging the substrate of BCRP with acceptable prediction performance in clinical studies is shown. Additional clinical investigations with known BCRP inhibitors are needed to fully validate and showcase the utility of this biomarker.

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.

BACKGROUND: Many of the cancer cases in Zimbabwe are HIV related, making it a significant health concern in the country. This concern requires innovative ways, such as implementing Value-Added Tax (VAT) to finance cancer management through health insurance. The study explores the general public, cancer patients, and public authorities' perception regarding using the VAT system for financing cancer treatment. METHOD: A qualitative cross-sectional study was conducted to explore the perception of study participants on 'Value Added Tax' as a source of healthcare financing in Harare. This was done through the use of in-depth interview guides. A total of 25 participants took part in the study. Fifteen were members of the general public, 5 were cancer patients, and 5 were key informants representing public authority. Members of the general public and cancer patients were conveniently selected, while key informants were purposively selected. Data were analyzed descriptively and by grounded theory whereby codes were developed by induction. RESULTS: The general public and cancer patients perceived cancer treatment as generally unaffordable and showed readiness to pay for a cancer levy through VAT. Cancer patients expressed disappointment at the low support for cancer treatment compared to HIV treatment concerning the already established AIDS levy. Public authorities also perceived the VAT system as an appropriate programme for health care financing. CONCLUSION: This preliminary study found that a 'Value-Added-Tax' system could potentially be an acceptable model to finance public healthcare, including cancer treatment in highly informal settings like Zimbabwe.

Hepatitis B and C cause chronic infections which develop into liver-related sequelae, like cirrhosis and liver carcinoma. This study determined the seroprevalence, trends, and risk factors of HBV and HCV among family replacement donors. A retrospective review of primary data on blood donors screened between January 2015 and December 2021 was conducted at Sunyani Municipal Hospital. The data were assessed for seroprevalence, trends, and odds ratios using SPSS. Of 6847 donors, the majority were males (88.1% [6033]), ≤24 years (27.4% [1874]), O blood type (69.8% [4776]), and Rh-positive (89.9% [6154]). The seroprevalences of HBV and HCV were 3.2% and 1.9%, respectively, with more males infected with HBV and HCV (3.4% vs 2.0%). Males were 2.842 times (p = .001) and 2.399 times (p = .025) more susceptible than females to HBV and HCV, respectively. In the rainy season, donors were 1.489 times (p = .041) more susceptible to HCV. HBV and HCV seroprevalence declined over the period (slope: -0.5464, p ≤ .001 vs slope: -0.6179, p ≤ .001). Male gender and rainy season were significant determinants of both infections. The seroprevalence of HBV was higher than HCV despite the significant decline in both infections. We, recommend health authorities intensify health education among males and during the rainy season.

INTRODUCTION: The Coronavirus Disease 2019 (COVID-19) pandemic has resulted in a major breakdown of health service provision in the fight against neglected tropical diseases (NTDs). COVID-19 may impact NTDs service delivery in varied ways. As the Ghana NTD programme planned to resume MDA activities, we examined the COVID-19 related perceptions and practices among some community members and frontline health workers for NTD control activities in the country. METHODS: The study was conducted in seven communities in the Ahanta West district of Ghana. This was a qualitative study using in-depth interviews (IDI) and focus group discussions (FGDs) for data collection. Participants were purposively selected from varied backgrounds to represent both beneficiaries and service providers directly involved in NTD programme implementation. Trained and experienced qualitative data collectors conducted the FGD and IDI sessions in the local Twi language, while health worker sessions were conducted in English. Discussions were audio-recorded and transcribed directly into English. Data was analysed using an iterative process. The transcripts were pre-coded using the broad themes, entered into a computer using Microsoft Word, and then imported into the MAXQDA software for thematic content analysis to select relevant representative narratives for presentation. RESULTS: Participants were aware of the COVID-19 pandemic and referred to it appropriately as 'coronavirus', COVID-19, and often as 'the new disease'. Though many respondents could not describe the route of transmission, most of them reported that it is transmitted through touch or sharing of common items. They reported some signs/symptoms like fever, headache and difficulty breathing, and prevention methods like the use of hand sanitiser, washing of hands and sneezing appropriately. Respondents have reported that COVID-19 has negatively affected their daily lives by limiting their movements and therefore work. It also came to light that COVID-19 has also negatively affected the NTD programme implementation, especially mass drug administration (MDA) activities, leading to the postponement of the yearly MDA. The COVID-19 pandemic has negatively affected clinic attendance; people are afraid that they may be tested for COVID-19 at the clinic. CONCLUSION: COVID-19 has negatively affected the NTD programme. Education and the provision of personal protective equipment will be required to build the confidence of frontline care providers including community drug distributors and community members in order to enhance quality service and participation in future MDA activities.

BACKGROUND: Medication adherence is important to the survival of People Living with HIV (PLHIV) globally. Although, HIV viral load is reduced by antiretroviral therapy (ART), the number of people on ART continues to rise in Ghana. In the Kumasi Metropolis, Ghana, we looked at the socio-demographic factors associated with medication adherence among PLHIV. METHODS: A quantitative study involving 420 PLHIV who sought healthcare at the Kumasi South Regional Hospital was conducted utilizing a cross-sectional study design. We employed a structured questionnaire to collect data on medication adherence using the eight-item Morisky Medication Adherence Scale (MMAS) and socio-demographic factors that influence medication adherence. The data were analysed using Stata 14.2. Frequencies and percentages were used to present the descriptive data. The association between socio-demographic factors and medication adherence among PLHIV was investigated using both univariate and multivariate analyses. RESULTS: More than half (53.10%) of PLHIV adhered to ART. Place of residence was significantly established to be influencing medication adherence among PLHIV. PLHIV who were residing in urban centers (aOR = 3.61; CI = 2.24-5.82) were more likely to adhere to medication as compared to those who resided in rural areas. CONCLUSION: Slightly more than half of PLHIV took their medicines as prescribed. Government and Policymakers such as the Ghana AIDS Commission, Ministry of Health, and Ghana Health Service should incorporate socio-demographic factors such as place of residence while creating and executing medication adherence initiatives to evaluate HIV management regimen for PLHIV.

BACKGROUND: Cancer is one of the leading causes of death globally. Owing to high toxicity, patients using chemotherapy drugs have a higher risk for developing adverse drug reactions (ADRs). Pharmacovigilance studies are essential in oncology to evaluate ADRs caused by anticancer drugs and improve patient safety. This study aimed to analyze serious ADRs associated with the use of doxorubicin and epirubicin reported to VigiBase. METHOD: All anonymized data on suspected ADRs for doxorubicin and epirubicin as 'serious' and 'suspected' or 'interacting' drugs between 1968 and 30 August 2021, were extracted from VigiBase. Descriptive statistics were conducted in Microsoft Excel, and data were summarized using frequencies and percentages. RESULTS: A total of 35,620 serious individual case safety reports was analyzed. The majority of reports were from females (Dox = 61.41%; Epi = 86.56%), while the predominant age group was 45-64 years (Dox = 42.06%; Epi = 57.39%). Physicians were the more likely group to report serious ADRs (Dox = 50.03%; Epi = 34.11%). In general, Europe reported the highest for doxorubicin (38.08%), while Asia recorded the highest reports for epirubicin (53.28%). Oceania reported the least for both drugs (Dox = 0.45%; Epi = 0.04%), followed by Africa (Dox = 0.72%; Epi = 0.29%). Blood and lymphatic system disorders were the most reported serious category (Dox = 11053 [44.47%]; Epi = 6659 [61.84%]). The most common manifestations were febrile neutropenia (Dox = 10.52%) and bone marrow failure (Epi = 23.89%). CONCLUSION: This study provides relevant global insights into serious ADRs for doxorubicin and epirubicin. This knowledge may assist in minimizing and proactively managing ADRs. It can also inform policies to improve patients' quality of life.
RESUMO
INTRODUCTION: Though there are controversies, cancer screening has been suggested to decrease mortality. Over the years, the most accessible primary healthcare provider; the community pharmacist, has developed an interest in being part of cancer screening activities and prevention of a wide range of other non-communicable diseases. To achieve this, community pharmacists need a working knowledge of the basic screening test and recommendations. Also, it's important to acknowledge the barriers that may prevent the implementation of cancer-screening efforts at the community pharmacy. This study aims to determine the knowledge and barriers to cancer screening among Ghanaian community pharmacists. METHODOLOGY: Knowledge and barriers to cancer screening was assessed using an online questionnaire in 435 community pharmacists. Descriptive statistics and Pearson's chi-squared tests were used to analyze the data. RESULTS: The reliability and validity assessment of the questionnaire after data collection revealed a Cronbach's alpha value of 0.82 for knowledge on cancer screening. The SD and mean age of study participants were 2.48 ± 20.08. Only 25.7% of the participants had good knowledge. The most identified barrier was the lack of established guidelines (60.9%). There was no association between participants' demographics and their knowledge scores. CONCLUSIONS: Community pharmacists can potentially have a large impact on early detection of cancer through screening. However, they have to improve their knowledge on general screening guidelines and be aware of available educational resources to increase their knowledge. It is also important for all stakeholders to come together to establish local screening modalities and recommendations for the country.

INTRODUCTION: Community pharmacists may play a vital role in early detection and prevention of cancer. Findings from our pre-assessment studies showed that the Ghanaian community have inadequate knowledge of cancer. We assessed the impact of a brief educational intervention on knowledge level of cancer among Ghanaian community pharmacists. METHOD: The study was a descriptive interventional study. Knowledge of cancer, signs and symptoms, risk factors and cancer screening tests were assessed before in a pre-assessment study and after a brief online education in our current study. A total of 435 community pharmacists were recruited in both studies. RESULTS: The mean ± SD total knowledge score of cancer increased from 9.03 ± 2.65 to 12.97 ± 1.43 out of a maximum score of 15 points. The mean ± SD total knowledge score of signs and symptoms of cancer increased from 4.15 ± 2.14 to 6.86 ± 0.76 out of a maximum score of 7 points. For the total knowledge score of causes and risk factors of cancer, the mean ± SD score increased from 8.13 ± 3.31 to 11.59 ± 0.87 out of a maximum score of 12 points. Lastly, the mean ± SD total knowledge score of cancer screening tests increased from 9.04 ± 5.01 to 16.39 ± 0.86 out of a maximum score of 18 points. CONCLUSION: There were overall statistically significant improvements of participants knowledge in all aspects of cancer in this study compared to the pre-assessment study. Our study presents evidence of the effectiveness of a brief educational intervention tailor-made for Ghanaian community pharmacists.

INTRODUCTION: The coronavirus of 2019 pandemic has necessitated vast and rapid changes in the way oncology pharmacy services are delivered around the world. METHODS/AIMS: An international survey of oncology pharmacists and technicians was conducted via the International Society of Oncology Pharmacy Practitioners and collaborating global pharmacy organisations to determine the impact that the coronavirus of 2019 has had on pharmacy service delivery, pharmacy practitioners and oncology practice. RESULTS: The survey received 862 responses from 40 different countries from September to October 2020. The majority of respondents were pharmacists (n = 841, 97.6%), with 24% involved in the direct care of patients with the coronavirus of 2019. Of the survey participants, 55% increased their time working remotely, with remote activities including dispensing, patient assessment/follow-up and attending multi-disciplinary rounds. Respondents reported a 72% increase in the use of technology to perform remote patient interaction activities and that participation in educational meetings and quality improvement projects was reduced by 68% and 44%, respectively. Workforce impacts included altered working hours (50%), cancelled leave (48%) and forced leave/furloughing (30%). During the pandemic, respondents reported reduced access to intensive care (19%) and anti-cancer (15%) medications. In addition, 39% of respondents reported reduced access to personal protective equipment, including N95 masks for chemotherapy compounding. Almost half of respondents (49%) reported that cancer treatments were delayed or intervals were altered for patients being treated with curative intent. A third of practitioners (30%) believed that patient outcomes would be adversely impacted by changes to pharmacy services. Sixty-five percent of respondents reported impacts on their mental health, with 12% utilising support services. CONCLUSION: The coronavirus of 2019 pandemic has altered the way oncology pharmacy services are delivered. These results demonstrate the adaptability of the oncology pharmacy profession and highlight the importance of formal evaluation of the varied practice models to determine the evidence-based practices that enhance pharmacy services and, thus, should be reinstated as soon as practical and reasonable.

BACKGROUND: Over the years, the prevalence of prostate cancer (PCa) has been on the increase. Poor prognosis has been a reflection of increased advance-staged diagnosis and inadequate financial assistance. The prioritization of resources cannot be effective enough to factor in the unexpected economic burden resulting from ill health unless health economic approaches are utilized to estimate the cost of diseases including PCa. With the absence of data on the cost of PCa in Ghana, and the evidence of the benefits of PCa cost-of-illness studies on cancer financing, it has become imperative to investigate the direct health cost of PCa on patients and careers. Hence, we investigate the cost of PCa diagnosis and management, the availability and prices of PCa medications, and the affordability of PCa care in Ghana. METHODS: The prevalence approach to cost-of-illness studies was adopted in this study through a random selection of two (2) hospitals, four (4) private laboratories, and ten (10) private community pharmacies in the Ashanti Region of Ghana. The diagnostic and management cost of PCa was investigated through the application of validated data collection instruments to representatives of the selected hospitals and laboratories. The availability and prices of PCa medications were studied with the administration of a validated tool to representatives of the selected pharmacies. The data were analyzed with Microsoft Excel Spreadsheet and the affordability of care was assessed considering the 2021 Ghana National Daily Minimum Wage (GNDMW). RESULTS: The cost of diagnosing non-metastatic and metastatic PCa were respectively estimated at GHC 1686.00 ($ 290.58) and GHC 6876.00 ($ 1185.09). Radical prostatectomy, as a management option, was estimated at GHC 2150.00 ($ 370.56) higher than Extended Beam Radiotherapy (GHC 2150.00: $ 370.56). The mean PCa drug availability for the sampled pharmacies around the public hospital, all the sampled pharmacies, and around the private hospital were respectively 61.54, 51.54, and 41.54%. None of the sampled drugs at the stated strengths had a 100% availability. A 6-month androgen deprivation therapy employing goserelin was GHC 3000.00 ($ 517.05). The median drug price ratio (MDPR) was 0.72 - 15.38, with generic bicalutamide 150 mg tablets as the cheapest and generic flutamide 250 mg tablets as the most expensive. CONCLUSION: The diagnostic and management cost of PCa currently overwhelms the average Ghanaian because the minimum daily wage in 2021 is GHC 12.53 ($ 0.46). A higher economic burden was associated with metastatic PCa and hence, the need for strategies to improve early detection. Also, the inclusion of PCa management in the National Health Insurance Scheme would lessen the financial burden of the disease on patients and careers, and improve management outcomes.

Social and Behavior Change Communication is a vital strategy in the control of malaria. However, the effectiveness of fear appeal tactic as a preventive strategy remains uncertain. This study examined the influence of a fear appeal mobile phone-based intervention, guided by Witte's Extended Parallel Process model, on malaria prevention among caregivers with children under-five. We conducted a quasi-experimental study of a 12-month intervention using a sample of 324 caregivers from two rural districts, assigned to either an intervention or control group. The intervention group received fear appeal voice Short Message Service (SMS), once a week for twelve (12) months, while caregivers in the control group received none. The results showed that exposure to the messages was associated with an increased odds of positive attitude [adjusted Odds ratio (aOR) = 2.58; 95% CI 1.61-4.15] and behavioral changes (aOR = 2.03, 95% CI 1.29-3.19). The intervention group exhibited lower odds of defensive avoidance (aOR = 0.44, 95% CI 0.29-0.68) and message minimization (aOR = 0.51, 95% CI 0.33-0.78) compared with the control group. These findings highlight the importance of communicating health messages via mobile phones using fear appeal for improving the health behaviors of caregivers. This strategy, however, may not be useful for influencing the intention of caregivers to engage in positive health practices to protect their children from malaria.

INTRODUCTION: Access to childhood cancer medicines is a critical global health challenge. There is a lack of sufficient context-specific data in Ghana on access to essential medicines for treating childhood cancers. Here, we present an analysis of essential cancer medicine availability, pricing, and affordability using the pediatric oncology unit of a tertiary hospital as the reference point. METHOD: Data on prices and availability of 20 strength-specific essential cancer medicines and eight non-cancer medicines were evaluated using the modified World Health Organization (WHO)/Health Action International method. Two pharmacies in the hospital and four private pharmacies around the hospital were surveyed. We assessed their median price ratio using the WHO international reference price guide. The number of days wages per the government daily wage salary was used to calculate the affordability of medicines. RESULTS: The mean availability of essential cancer medicines and non-cancer medicines at the hospital pharmacies were 27 and 38% respectively, and 75 and 84% respectively for private pharmacies. The median price ratio of cancer medicines was 1.85, and non-cancer medicines was 3.75. The estimated cost of medicines for treating a 30 kg child with Acute lymphoblastic leukaemia was GHÈ» 4928.04 (US$907.56) and GHÈ» 4878.00 (US$902.62) for Retinoblastoma, requiring 417 and 413-days wages respectively for the lowest-paid unskilled worker in Ghana. CONCLUSION: The mean availability of cancer medicines at the public and private pharmacies were less than the WHO target of 80%. The median price ratio for cancer and non-cancer medicines was less than 4, yet the cost of medicines appears unaffordable in the local setting. A review of policies and the establishment of price control could improve availability and reduce medicines prices for the low-income population.

Low and middle-income countries (LMICs) are the epicenter of the HIV epidemic. The scale-up of antiretroviral therapy (ART) has reduced mortality, but HIV-associated neurocognitive impairment (HANI) remains prevalent, which impacts functional performance, medication adherence, and quality of life. We aimed to evaluate the effect of ART on neurocognitive outcomes among people living with HIV/AIDS in LMICs and to identify determinants of these outcomes. We searched electronic databases and reference lists for studies published between 1996 and 2019. Two reviewers screened the primary studies for inclusion and performed the critical appraisal. Results were synthesized using the 'Synthesis without meta-analysis' approach through simple vote counting. We identified 31 studies conducted across four regions (Africa, Asia, South America, and Eastern Europe). Nine studies were cross-sectional, 15 were prospective, and seven were randomized controlled trials. The majority of the articles showed improved neurocognitive performance with ART use but found no association with treatment duration, regimen, central penetrating effectiveness, and conventional biomarkers. Despite the lack of appropriate norms and not accounting for practice effect in most studies, the evidence suggests ART is useful in the treatment of HIV-associated neurocognitive impairment (HANI) but limited in addressing legacy effects, and peripheral, and central viral reservoirs. Improved early ART treatment programs, viral reservoir eradication strategies, and identification of novel biomarkers will be critical in efforts to minimize HIV-associated neurocognitive impairment.

PURPOSE: We aimed to explore the experiences of husbands of women diagnosed with advanced breast cancer, highlighting their stressors and the resources they rely on to cope, in Kumasi, Ghana. METHOD: An exploratory descriptive qualitative research design was adopted. Fifteen in-depth interviews with participants were conducted. After a participant's written consent, we audio-recorded the interview sessions and transcribed them verbatim. We managed and analysed the data manually. RESULT: The experiences of husbands as primary caregivers of their wives diagnosed with advanced breast cancer have been broadly categorized under two main themes: stressors and resources. The analyses revealed that the burdens associated with the husband's primary caregiving roles threatened the marriage, their relationships with others, work, and finances. Regardless of the stressors, participants drew on a range of resources such as acceptance, marital obligation and commitment to marital vows, social support, and spirituality to cope. CONCLUSION: The study is the first of our knowledge to explore the experiences of husbands acting as primary caregivers of their wives who are diagnosed with advanced breast cancer in Ghana. It revealed that they rely on specific resources to cope with the burdens associated with their role. Policies and programs aiming at assisting women diagnosed with advanced breast cancer to manage and cope with the disease should include the partners of the married ones by designing programs that help the husbands to understand the situation and adequately provide the care that promotes the quality of life of the husband, wife, and the family.

OBJECTIVES: The goal of this study was to access the knowledge of a representative sample of community pharmacists in Ghana on general cancer, risk factors, signs and symptom and most common cancer counseling points known to community pharmacists. METHODS: A structured online questionnaire was administered to 435 registered community pharmacists in the sixteen regions of Ghana.Key findings: Mean score for knowledge of cancer among community pharmacists was 6.8 ± 1.61 points out of a maximum score of 15 points, categorizing the overall knowledge as inadequate. The overall assessment of pharmacists' knowledge revealed that 74.6% of the participants had inadequate level of knowledge on cancer. Mean score for knowledge of cancer signs and symptoms among community pharmacists was 3.55 ± 1.85 out of a maximum score of 7 points, categorizing the overall knowledge as inadequate. The overall evaluation indicated that 79.03% of pharmacists had inadequate knowledge of signs and symptoms cancer. Mean score for knowledge of risk factors of cancer among community pharmacists was 5.25 ± 1.15 out of a maximum score of 12 points, categorizing the overall knowledge as inadequate. The overall assessment of the knowledge score indicates that 70.34% of pharmacists had inadequate knowledge about causes and risk factors of cancer. Almost all participating pharmacists (96.5%) recommended counselling point was avoidance of smoking as a cancer preventive measure. An inverse significant correlation was found between age and knowledge scores of signs and symptoms of cancer (r = -0.077, P = 0.038). There was a statistically significant relationship between pharmacists' level of knowledge on cancer (whether adequate or inadequate) and the cancer items. CONCLUSIONS: Knowledge of cancer, its signs and symptoms and its risk factors were inadequate among community pharmacists in Ghana. Efforts should be made to improve knowledge of community pharmacists on cancer through continuous education. Also, undergraduate pharmacy training in oncology should encourage to close knowledge gap of community pharmacists on cancer.

BACKGROUND: In the absence of microscopy, Plasmodium falciparum histidine-rich proteins 2 (PfHRP2)-based rapid diagnostic tests (RDTs) are recommended for the diagnosis of falciparum malaria, particularly in endemic regions. However, genetic variability of the pfhrp2 gene threatens the usefulness of the test due to its impact on RDT sensitivity. This study aimed to investigate the diversity of pfhrp2 in malaria cases among children in Ghana. METHODS: A cross-sectional study was conducted at the Adidome Government Hospital in the Volta Region of Ghana. A total of 50 children with mean age of 6.6 ± 3.5 years and diagnosed falciparum malaria were included. Blood samples were collected for complete blood count, malaria parasite identification and counting using auto analyzer and microscopy, respectively. DNA was isolated from blood-spotted Whatman filters, amplified and sequenced. Nucleotide sequences were translated in silico to corresponding amino acids and the deduced amino acids sequences were analyzed for diversity using Mega X. RESULTS: The number of repeats and number of each repeat within PfHRP2 varied between isolates. Twelve rare PfHRP2 repeat types, two of which are previously unreported, were identified in this study. The HRP2 sequence obtained in this study shared high similarities with isolates from Kenya. Using Baker's regression model, Group B was the highest occurring type (58.0%). Screening of all sequences for epitopes recognized by PfHRP2-specific monoclonal antibodies (mAbs), the predominant motif was AHHAADAHH, which is recognized by the C1-13 mAbs. CONCLUSION: This study reports diversity of P. falciparum HRP2 in samples from Ghanaian children with symptomatic malaria. The findings of this study highlight the existence of extra amino acid repeat types which adds to the PfHRP2 antigenic variability.

METHODS: A cross-sectional study was conducted using electronic questionnaire to assess the perception and perceived barriers of Ghanaian community pharmacists towards provision of cancer health promotion. KEY FINDINGS: The majority of community pharmacists (77.30%) believe that cancer health promotion is an important part of their daily practice. The survey participants were more likely to have a positive perception of the role of the pharmacist if they were older, male, Christian, or had completed the PharmD program (p < 0.05 for all parameters). Lack of cancer educational materials (69%) was the major perceived barrier in providing cancer health promotion services. CONCLUSION: Ghanaian community pharmacists recognise to play an important role in the provision of cancer health promotion service.

Ataxia-Telangiectasia (AT) is an immunodeficiency most often associated with T cell abnormalities. We describe a patient with a hyper-IgM phenotype and immune cell abnormalities that suggest a distinct clinical phenotype. Significant B cell abnormalities with increased unswitched memory B cells, decreased naive transitional B cells, and an elevated frequency of CD19+CD38loCD27-CD10-CD21-/low B cells expressing high levels of T-bet and Fas were demonstrated. The B cells were hyporesponsive to in vitro stimulation through the B cell receptor, Toll like receptors (TLR) 7 and 9, and CD40. T cell homeostasis was also disturbed with a significant increase in γδ T cells, circulating T follicular helper cells (Tfh), and decreased numbers of T regulatory cells. The ATM mutations in this patient are posited to have resulted in the perturbations in the frequencies and distributions of B and T cell subsets, resulting in the phenotype in this patient. KEY MESSAGES: A novel mutation creating a premature stop codon and a nonsense mutation in the ATM gene are postulated to have resulted in the unique clinical picture characterized by abnormal B and T cell populations, lymphocyte subset dysfunction, granuloma formation, and a hyper-IgM phenotype. CAPSULE SUMMARY: A patient presented with ataxia-telangiectasia, cutaneous granulomas, and a hyper-IgM phenotype; a novel combination of mutations in the ATM gene was associated with abnormal distributions, frequencies, and function of T and B lymphocyte subsets.

BACKGROUND: Poor maternal health delivery in developing countries results in more than half a million maternal deaths during pregnancy, childbirth or within a few weeks of delivery. This is partly due to unavailability and low utilization of maternal healthcare services in limited-resource settings. The aim of this study was to investigate the access and utilization of maternal healthcare in Amansie-West district in the Ashanti Region of Ghana. METHODS: An analytical cross-sectional study, involving 720 pregnant women systematically sampled from antenatal clinics in five sub-districts was conducted from February to May 2015 in the Amansie-West district. Data on participants' socio-economic characteristics, knowledge level and access and utilization of maternal health care services were collected with a structured questionnaire. Odds ratios were estimated to describe the association between explanatory variables and maternal healthcare using generalized estimating equations (GEE). RESULTS: 68.5, 83.6 and 33.6% of the women had > 3 antenatal care visits, utilized skilled delivery and postnatal care services respectively. The mothers' knowledge level of pregnancy emergencies and newborn danger signs was low. Socio-economic characteristics and healthcare access influenced the utilization of maternal healthcare. Compared to the lowest wealth quintile, being in the highest wealth quintile was associated with higher odds of receiving postnatal care (adjusted odds ratio [aOR]; 95%CI: 2.84; 1.63, 4.94). Use of health facility as a main source of healthcare was also associated with higher odds of antenatal care and skilled delivery. CONCLUSION: This study demonstrates suboptimal access and utilization of maternal healthcare in rural districts of Ghana, which are influenced by socio-economic characteristics of pregnant mothers. This suggests the need for tailored intervention to improve maternal healthcare utilization for mothers in this and other similar settings.
