RESUMEN

INTRODUCTION: Despite breakthroughs in cervical cancer detection, resource-constrained countries continue to have a disproportionately high incidence and death rate. Mhealth has been identified as an important tool for increasing cervical cancer screening rates in Sub-Saharan Africa. We determined whether sending Ghanaian women culturally tailored one-way mobile phone SMS text messages about cervical cancer would encourage the uptake of the human papillomavirus (HPV) test. METHODS: From August to November 2016, 88 women aged 18 to 39 living or working in an urban community (Accra, Ghana) participated in a quasi-experimental study. For 8 weeks, 32 SMS messages regarding cervical cancer were developed and sent to the personal phones of intervention arm participants (n = 42). Women in the control group (n = 46) received SMS texts with general health and lifestyle advice. Fischer's exact tests were performed to assess cervical cancer screening uptake and associated reasons for non-uptake between the intervention and control groups (p < 0.05). RESULTS: At the baseline, women differed in terms of ethnicity and wealth. After the intervention, participants' self-reported risk factors for cervical cancer, such as early menarche, usual source of medical treatment, family history of cancer, smoking, and alcohol history, changed. None of the women in the intervention group sought cervical cancer screening after the intervention, but only one (2.2%) of the control arm participants did. Almost all the women (> 95%) agreed that an HPV test was essential and that regular healthcare check-ups could help prevent cervical cancer. Some women believed that avoiding particular foods could help prevent cervical cancer (23.8% intervention vs. 58.7% control, p < 0.001). Time constraints and out-of-pocket expenses were significant barriers to cervical cancer screening. CONCLUSION: A one-way SMS delivered to urban women did not increase cervical cancer screening attendance. The time spent in screening facilities and the lack of coverage by the National Health Insurance Scheme limited screening uptake. We urge for the establishment of screening centers in all healthcare facilities, as well as the inclusion of cervical cancer screening in healthcare programs through cost-sharing.

RESUMEN

INTRODUCTION: Globally breast cancer is the leading cause of cancer with an estimated 2.3 million new cases and 685,000 deaths in 2020. Late presentation is the hallmark of breast cancer in Ghana for which ignorance and fear are the major reasons fuelled largely by myths and misconceptions. Breast cancer awareness and education needs to start early to bring about a change in knowledge, attitude and practices. However, Breast cancer awareness activities in Ghana have usually targeted adult women. This study assessed the impact of breast cancer education among adolescent high school girls in Ghana. METHODOLOGY: A pre- post-test quasi experimental study was conducted at two senior high schools. A self-administered pre-educational questionnaire was followed by an educational intervention consisting of a drama, PowerPoint lecture, question and answer session and distribution of breast cancer information leaflets. After 3 months the same questionnaire was administered as a post-education test to assess the impact of the educational intervention. The total score for each domain was categorised into adequate knowledge > 50% and inadequate knowledge < 50%. RESULTS: The number of participants in the pre-test and post-test were 1043 and 1274; the median ages [IQR] were 16.0 [15.0-17.0] for both the pre and post-test students. General knowledge on breast cancer at pre-education (29.1%) improved to 72.5% (p < 0.001). Knowledge on signs and symptoms improved from 33.1 to 55% (p < 0.001); knowledge on risk factors improved from 55.3 to 79.2% (p < 0.001), and knowledge on breast self-examination and screening improved from 9.8 to 22.2% (p < 0.001). The overall performance of the students improved from 17.2 to 59.4% (p < 0.001). CONCLUSION: There is inadequate knowledge about breast cancer and self-examination among senior high school girls in Ghana. Our breast cancer educational intervention was effective in improving general knowledge of breast cancer, risk factors, signs and symptoms and breast self-examination. The overall knowledge base improved from 17.2 to 59.4% 3 months post intervention, accompanied by an increase in the reported practice of breast self-examination and a greater belief that breast cancer is curable. This study has demonstrated the need for a school breast cancer educational program and that breast cancer education in high schools is effective.

RESUMEN

BACKGROUND: There has been extensive research across the globe to understand the barriers and facilitators of cervical cancer (CC) screening. However, few studies have focused on how such information has been used to develop text messages for mHealth screening programs, especially in resource-poor countries. This study elicited information on barriers and facilitators, the preferences of women regarding the modalities for delivery of health SMS messages on screening for cervical cancer, and demonstrates how this information was used to create a health screening program among women in the Greater Accra Region of Ghana. METHODS: Four main activities were carried out, including (1) a total of five focus group discussions, (2) a baseline survey involving 62 female bankers and 68 women from the communities, (3) a stakeholder meeting involving experts in cervical cancer research and clinical care, and (4) pilot testing of the text messages. Focus group discussions and the baseline survey data were collected concurrently between February and May 2017 and the results were used to develop 5 specific communication objectives during the stakeholder engagements held in June 2017. RESULTS: In all, 32 text messages were developed and pretested in July 2017(13 addressed knowledge on CC; 6 highlighted the importance of early detection; 5 allayed fear as a barrier to CC screening; 5 encouraged women to have time for their health, and 3 messages contained information on where to go for screening and the cost involved). Although awareness about the disease was high, knowledge of CC screening was low. For two-thirds of respondents (22/33), perceived lack of time, high cost, and fear (of cc, screening procedure, and potential for negative outcome) accounted for the reasons why respondents will not go for screening, while education on CC, especially from health workers and the mass media enabled uptake of CC screening. CONCLUSION: Several factors prevent women from accessing screening services for CC, however, barriers such as low levels of education on CC, lack of time, and fear can be targeted in SMS messaging programs.

RESUMEN

BACKGROUND: Breast cancer is a heterogeneous disease composed of multiple subgroups with different molecular alterations, cellular composition, clinical behaviour, and response to treatment. This study evaluates the occurrence of the various subtypes and their clinical and pathological behaviour in the Ghanaian breast cancer population at the Korle Bu Teaching Hospital (KBTH). METHODS: Retrospective review of case notes of patients who had completed treatment for breast cancer at the KBTH within the last 5 years was conducted between April 2011 and March 2012. Subtypes were determined by immunohistochemistry classification based on expression of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor-2 (HER-2). RESULT: A total of 165 cases contributed to this study. The mean age at diagnosis was 52.5 ± 12.1 years. Tumour size ranged from 0.8 cm to 15 cm with a mean of 4.9 ± 2.8 cm and median of 4 cm. Tumour grade was Grade I 8.3 %, Grade II 60.8 % and Grade III 30.8 %. ER, PR and HER2/neu receptor positivity was 32.1, 25.6 and 25.5 % respectively. Almost half (49.4 %) of the study population had triple negative tumours. Luminal A, luminal B and non-luminal HER2 were 25.6, 12.2, and 12.8 % respectively. No statistically significant association was seen between subtype and tumour size, tumour grade, lymph node status and age at diagnosis. CONCLUSION: Triple negative tumour is the most occurring subtype in the Ghanaian breast cancer population treated at the Korle Bu Teaching Hospital. Lack of association seen between subtypes and their clinical and pathological behaviour could be due to small sample size.

RESUMEN

Introduction: breast cancer development is linked to mutant single nucleotide polymorphism of breast cancer type 1 (BRCA1) gene usually harboured within exon 11. It has also been linked to finger dermatoglyphics where certain patterns have been associated with breast cancer. This study suggests a possible relationship between finger dermatoglyphic patterns and single nucleotide polymorphism of BRCA1 gene. Methods: in a quantitative cross-sectional approach, finger dermatoglyphic patterns were obtained using the ink method from 70 female breast cancer patients and 70 age-matched apparently healthy females. Approximately 5 ml of venous blood was obtained from each participant from which DNA was extracted from the white blood cells collected after centrifugation. DNA was amplified and sequenced and the data aligned with the wildtype template of BRCA1 gene. Fingerprint patterns were analyzed with Chi-square. Mean frequency of fingerprint patterns was analyzed with independent student's t-test. Differences in data set with p<0.05 were statistically significant. Results: luminal B was the predominant breast cancer molecular subtype among the patients. The predominant fingerprint pattern among breast cancer participants was the loop. Six or more loops had higher frequency among breast cancer females. The predominant BRCA1 gene variant locations were c.34311, c.34320, and c.34321 with c.34311A>C being the predominant variant. Higher percentage frequency of six or more loops in relation to c.34311A>C was observed in apparently healthy females compared to breast cancer females. Conclusion: the study reports for the very first time in Ghana, BRCA1 gene variants and finger dermatoglyphics among breast cancer patients. Although the results are preliminary and inconclusive it creates an avenue for extended studies.

RESUMEN

Breast cancer is the most common malignancy in women, with alarming mortalities. Neoadjuvant treatments employ chemotherapy to shrink tumours to a well-defined size for a better surgical outcome. The current means of assessing effectiveness of chemotherapy management are imprecise. We previously showed that breast cancer patients have higher serum circulating cell-free DNA concentrations. cfDNA is degraded cellular DNA fragments released into the bloodstream. We further report on the utility of cfDNA in assessing the response to chemotherapy and its potential as a monitoring biomarker. A total of 32 newly diagnosed and treatment-naive female breast cancer patients and 32 healthy females as controls were included. Anthropometric, demographic and clinicopathological information of participants were recorded. Each participant donated 5 mL of venous blood from which sera were separated. Blood sampling was carried out before the commencement of chemotherapy (timepoint 1) and after the third cycle of chemotherapy (timepoint 2). qPCR was performed on the sera to quantify ALU 115 and 247 levels, and DNA integrity (ALU247/ALU115) was determined. ALU 115 and 247 levels were elevated in cancer patients but were significantly decreased after the third cycle of chemotherapy (T2) compared to T1. DNA integrity increased after the third cycle. Serum cfDNA may provide a relatively inexpensive and minimally invasive procedure to evaluate the response to chemotherapy in breast cancer.

RESUMEN

INTRODUCTION: This study sought to identify the association of antibiotic prescribing and the risk of antibiotic-associated diarrhoea (AAD) in Korle Bu Teaching Hospital (KBTH) in Ghana. METHODOLOGY: Patients from the Male Urology Ward and Treatment Room of the Surgical Department of KBTH were followed up over three months to determine if they had experienced any unusual diarrhoeal illness after antibiotic therapy. 81 eligible patients (adults) were included in the study but a total of 70 patients (mean age of 56.71 years) were successfully followed up during the study period. RESULTS: The top conditions presented by patients were urological infection (66.7%), cancer (15.3%) and leg ulcer (18.1%). Ciprofloxacin (50%) and ceftriaxone (28.5%) were the most prescribed antibiotics. Eleven patients (more than 1 in 7) developed diarrhoea that could be associated with their use of antibiotics. The occurrence of AAD was significantly associated with type of antibiotic used by patient. 73% of patients who developed symptoms of AAD had received Clindamycin. Risk of AAD was not significantly associated with age and comorbidities. CONCLUSIONS: The rate of AAD in the Male Urology Ward and the Treatment Room of the Surgical Department of KBTH during the period of this study was 15.7%. Clindamycin was identified as the most implicated antibiotic.

RESUMEN

BACKGROUND: Breast cancer is the commonest malignancy in women worldwide. It is estimated to affect approximately 1.5 million women annually and responsible for the greatest number of cancer-related mortalities among women. In 2018, breast cancer mortalities stood at 627,000 women representing approximately 15% of all cancer deaths among women. In Ghana, breast cancer is the second leading cause of cancer deaths, with an incidence of 2,900 cases annually; one of eight women with the disease die. This gives impetus to the fight for improved early detection, treatment, and/management. In this light, we investigated the potential of death-associated protein kinase 1 (DAPK1) as a biomarker for breast cancer. As a tumour suppressor, its expression is activated by several carcinogens to influence cellular pathways that result in apoptosis, autophagy, immune response, and proliferation. AIM: To investigate DAPK1 as a blood biomarker for breast cancer. METHODS: Blood samples of participants diagnosed with breast cancer and healthy controls were collected and processed to obtain serum. Information on age, treatment, diagnosis, and pathology numbers was retrieved from folders. Pathology numbers were used to retrieve breast tissue blocks of patients at the Department of Pathology of the KBTH. Tissue blocks were sectioned and immunohistochemically stained with anti-DAPK1 and counterstained with hematoxylin to determine the DAPK1 expression levels. DAKP1 levels in blood sera were quantified using a commercial anti-DAPK1 ELISA kit. Case and control group means were compared using one-way ANOVA and Chi-square test. Statistical significance was set at p ≤ 0.05. Results and Discussion. DAPK1 levels were higher in sera and breast tissues of breast cancer patients than controls. The augmented DAPK1 expression can be interpreted as a stress response survival mechanism to remediate ongoing deleterious events in the cells orchestrated by carcinogenesis. In the presence of abundant DAPK1, the proliferative power of cells (both cancerous and noncancerous) is increased. This may explain why high DAPK1 expression strongly associates with aggressive breast cancer phenotypes like the ER-negative breast cancers, especially the triple-negative breast cancers (TNBC) which are the most aggressive, fast-growing, and highly metastatic. CONCLUSION: DAPK1 is highly expressed in sera and breast tissues of breast cancer patients than nonbreast cancer participants. The elevated expression of DAKP1 in circulation rather than in breast tissues makes it a candidate for use as a blood biomarker and potential use as therapeutic target in drug development.

RESUMEN

BACKGROUND: Cancer incidence and its related mortality is rising and is currently the second leading cause of death globally. In Africa, breast and prostate cancer in females and males, respectively, are the worst globally. However, biomarkers for their early detection and prognosis are not well developed. This study sought to investigate circulating cell-free DNA (ccfDNA) integrity and its potential utility as diagnostic and/or prognostic biomarker. Circulating cell-free DNA (ccfDNA) is degraded DNA fragments released into the blood plasma. In healthy individuals, the source of ccfDNA is solely apoptosis, producing evenly sized shorter DNA fragments. In cancer patients, however, necrosis produces uneven longer cell-free DNA fragments in addition to the shorter fragments originating from apoptosis. DNA integrity, expressed as the ratio of longer fragments to total DNA, may be clinically useful for the detection of breast and prostate cancer progression. METHODS: Sixty-four (64) females, consisting of 32 breast cancer patients and 32 controls, and 61 males (31 prostate cancer patients and 30 controls) were included in the study. Each participant donated 5 ml peripheral blood from which sera were separated. Real-time qPCR was performed on the sera to quantify ALU 115 and 247 levels, and DNA integrity (ALU247/ALU115) determined. RESULTS & CONCLUSION: ALU species 115 and 247 levels in serum were elevated in breast and prostate cancer patients compared to their counterpart healthy controls. DNA integrity was higher in prostate cancer patients than in the control, but in breast cancer patients was lower compared to their controls. In prostate but not in breast cancers, DNA integrity increased with disease severity and higher staging.

RESUMEN

Background: The global rise and spread of antibiotic resistance is limiting the usefulness of antibiotics in the prevention and treatment of infectious diseases. The use of antibiotic stewardship programs guided by local data on prescribing practices is a useful strategy to control and reduce antibiotic resistance. Our objective in this study was to determine the prevalence and indications for use of antibiotics at the Korle-Bu Teaching Hospital Accra, Ghana. Methods: An antibiotic point prevalence survey was conducted among inpatients of the Korle-Bu Teaching Hospital between February and March 2016. Folders and treatment charts of patients on admission at participating departments were reviewed for antibiotics administered or scheduled to be administered on the day of the survey. Data on indication for use were also collected. Prevalence of antibiotic use was determined by dividing the number of inpatients on antibiotics at the time of survey by the total number of patients on admission. Results: Of the 677 inpatients surveyed, 348 (51.4%, 95% CI, 47.6-55.2) were on treatment with antibiotics. Prevalence was highest among Paediatric surgery where 20/22 patients (90.9%, 95% CI, 70.8-98.9) were administered antibiotics and lowest among Obstetrics patients with 77/214 (36%, 95% CI, 29.5-42.8). The indications for antibiotic use were 245/611 (40.1%) for community-acquired infections, 205/611 (33.6%) for surgical prophylaxis, 129/611 (21.1%) for healthcare associated infections and 33/611 (5.4%) for medical prophylaxis. The top five antibiotics prescribed in the hospital were metronidazole 107 (17.5%), amoxicillin-clavulinic acid 82 (13.4%), ceftriaxone 17(12.1%), cefuroxime 61 (10.0%), and cloxacillin 52 (8.5%) respectively. Prevalence of meropenem and vancomycin use was 12(2%) and 1 (.2%) respectively. The majority of patients 181 (52%) were being treated with two antibiotics. Conclusion: This study indicated a high prevalence of antibiotic use among inpatients at the Korle-Bu Teaching Hospital. Metronidazole was the most commonly used antibiotic; mainly for surgical prophylaxis. There is the need to further explore factors contributing to the high prevalence of antibiotic use and develop strategies for appropriate antibiotic use in the hospital.
