Drug therapy problems among paediatric acute lymphoblastic leukaemia patients at Kenyatta National Hospital.

INTRODUCTION: Several studies reported that drug therapy problems (DTPs) were prevalent in cancer patients. These DTPs are still interfering with the desired treatment outcomes in patients with cancer. This study aimed to determine the prevalence, types and predictors of DTPs among paediatric acute lymphoblastic leukaemia (ALL) patients at Kenyatta National Hospital. METHODS: A retrospective cohort study was used to assess DTPs among ALL patients. Records of all eligible paediatric patients with ALL who received treatment in the facility between 1 January 2017 and 31 December 2021 were examined. A data abstraction tool was employed for data collection. The data entry and analysis were carried out by a statistical package for social sciences version 29.0 software. Frequency tables were utilised to present the key findings of the study. Binary logistic regression analysis was utilised to determine the predictors of DTPs. RESULTS: A total of 82 DTPs were identified with the most common type of DTP being adverse drug reaction (ADR; 59, 72.0%) and drug interaction (9, 11.0%). The most common ADRs identified were febrile neutropenia (20, 33.9%), nausea/vomiting (14, 23.7%) and anaemia (11, 18.6%). Patients with central nervous system disease (adjusted odds ratio [AOR] = 10.2, 95% CI = 1.2-85.8, p = 0.03) and treated with a combination of chemotherapy and radiotherapy (AOR = 13.5, 95% CI = 1.9-89.4, p = 0.01) were more likely to develop DTPs. CONCLUSION: The study found that the prevalence of DTPs among paediatric ALL patients was high, with the most common DTPs being ADRs occurring in 72.0% of patients. Central nervous system metastasis and a combination of chemotherapy and radiation treatment regimens were statistically significant predictors of DTPs.

Assessment of chemotherapy-related adverse drug reactions among multiple myeloma patients at Kenyatta national hospital.

BACKGROUND: Despite treatment modalities for multiple myeloma can cause adverse drug reactions (ADRs), data are scarce about the types, severity and preventability of chemotherapy-related ADRs in Kenya. This study aimed to assess the chemotherapy-related ADRs among multiple myeloma patients at Kenyatta National Hospital (KNH). METHODS: A one-arm retrospective cohort study was carried out among all eligible adult patients with a documented diagnosis of multiple myeloma between 1st January 2017 to 31st December 2023. A data abstraction tool was used to assess sociodemographics, clinical characteristics and chemotherapy-related ADRs. The Schumock and Thornton scale and the modified Hartwig and Siegel severity scale were employed to evaluate the preventability and severity of ADRs, respectively. Data analysis was performed using the Statistical Package for Social Sciences (SPSS) version 29.0 software. The results were presented using mean, frequency and percentage. Binary logistic regression was employed to assess factors influencing ADRs. A p-value of less than 0.05 was considered statistically significant. RESULTS: The prevalence of ADRs in this study was 81.5% with a total of 230 ADRs identified. The primary ADRs identified were peripheral neuropathy (21.7%), nausea and vomiting (14.8%), neutropenia (12.2%) and anemia (11.3%). The majority of the ADRs (51.7%) were moderate in severity, and 29.8% were of mild severity. Preventability assessments of the ADRs showed that most of them (68.2%) were definitely preventable and 13.2% were probably preventable. VRD (Bortezomib/Lenalidomide/Dexamethasone) and VCD (Bortezomib/Cyclophosphamide/Dexamethasone) treatment regimens were responsible for most of the ADRs. VRD (AOR = 11.1, 95% CI = 3.7-32.8, p < 0.001) and VCD treatment regimens (AOR = 4.8, 95% CI = 1.1-20.0, p = 0.033) were the significant factors affecting the occurrence of ADRs. CONCLUSION: Overall, the incidence of chemotherapy-related ADRs in multiple myeloma patients at KNH was notably high (81.5%). Despite the moderate severity of the ADRs, their preventable nature highlights the potential for improved patient outcomes through careful regimen selection and monitoring.

Assessment of adverse events among cervical cancer patients at Kenyatta National Hospital.

INTRODUCTION: Due to their cytotoxic nature, anticancer drugs and radiotherapy have the potential to cause toxic adverse events. As a result, they can increase the risk of morbidity and mortality. However, there was a lack of data among cervical cancer patients in our setting. Hence, this study was aimed to assess the prevalence of adverse events among cervical cancer patients at Kenyatta National Hospital. METHODS: A cross-sectional study design was employed among a consecutive sample of 151 adult cervical cancer patients. The data were collected by reviewing the medical records and interviewing the patients. The data were entered and analyzed using SPSS 27.0 software. The results were presented with frequency tables and graphs. RESULTS: A total of 214 adverse events (prevalence of 100%) were identified from 151 patients. The most common adverse events identified were ulcerated sores (52.8%), dysuria (7.5%), thrombocytopenia (5.6%), and loss of appetite (5.6%). The majority of the patients (80.8%) who had adverse events were on radiotherapy. As per the Naranjo causality assessment scale, the predominant (80.1%) proportion of the adverse event was a probable adverse event with a total score of 5-8. Besides, 15.9% of the adverse events had a possible causality. The present study also reported that 61.6% of patients with a probable adverse event were treated with radiotherapy. CONCLUSION: The prevalence of adverse events among cervical patients was high in our setting. The predominant proportion of the adverse event was a probable adverse event and most of them were treated with radiotherapy.

Health-related quality of life among cervical cancer patients at Kenyatta National Hospital.

BACKGROUND: Previous study showed that health-related quality of life (HRQoL) was adversely affected during treatment of cervical cancer, with a worsening global score. Therefore, this study aimed to determine the HRQoL of cervical cancer patients at Kenyatta National Hospital. METHODS: A cross-sectional study design was employed among cervical cancer patients. All eligible consecutive samples of 103 cervical cancer patients were included in the study. Following consent, patients were interviewed using The European Organization for Research and Treatment of Cancer Quality-of-Life Questionnaire 30 (EORTC QLQ-30) and Cervical Cancer Module CX24 (EORTC QLQ-CX24). The data were entered and analyzed using the SPSS version 20.0 software. Univariate and multivariate binary logistic regression analysis was employed to investigate the predictors of HRQoL. A p-value of ≤ 0.05 was considered statistically significant. RESULTS: The majority (69%) of the patients had a poor overall quality of life while 31% of study participants had a good quality of life. Patients with early-stage disease were 7.3 times (AOR = 7.3, 95% CI = 2.4-21.7, p = 0.000) more likely to have a good HRQoL than patients with advanced-stage disease. Patients with no comorbidities were 3.1 times (COR = 3.1, 95% CI = 1.1-9.1, p = 0.037) more likely to have a good HRQoL than patients with comorbidities. CONCLUSION: The overall HRQoL among cervical cancer patients was poor in the setting. Advanced stage of disease and presence of comorbidities were the significant predictors of poor quality of life.

Drug-related problems among esophageal, gastric and colorectal cancer patients at the National and referral hospital in Kenya.

INTRODUCTION: Cancer therapy has remarkable potential for drug-related problems due to the high cytotoxicity and narrow therapeutic index of most anti-neoplastic regimens. However, there is a lack of comprehensive studies on drug-related problems in patients with gastrointestinal cancer in Kenya. Therefore, the present study aimed to investigate the prevalence, types and predictors of drug-related problems among gastrointestinal cancer patients at Kenyatta National Hospital. METHODS: A cross-sectional study was used to assess the prevalence of drug-related problems among a random sample of 160 esophageal, 103 gastric, and 96 colorectal cancer patients. Data were collected using a researcher-administered questionnaire and data abstraction tool after training the data collectors. Patient-specific details such as socio-demographic features, histological cancer types, cancer stage, comorbidity types, and treatment regimen were recorded after the review of medical records and patient interviews. The potential of drug-related problems was determined as per the standard guidelines. The data were entered and analysed using version 26.0 SPSS statistical software. RESULTS: Most esophageal (51.9%), gastric (59.2%), and colorectal (62.5%) cancer patients had a high prevalence of drug-related problems. The need for additional drug therapy and adverse drug reactions were the predominant categories of drug-related problems. Most adverse drug reactions identified had possible categories of causality score, mild severity levels, and definitely preventable types of adverse drug reactions among all gastrointestinal cancer patients. Comorbidity and advanced-stage disease were significant predictors of drug-related problems. CONCLUSIONS: Drug-related problems were prevalent among gastrointestinal cancer patients in our setting. Comorbidity and advanced stages of disease were significant predictors of drug-related problems.

A Systematic Review of the Treatment Outcomes among Prostate Cancer Patients in Africa.

Prostate cancer (PCa) is associated with a significant public health burden in Africa. This systematic review aimed to assess treatment outcomes among PCa patients in Africa. A systematic search of the literature was conducted from 1 December 2021 to 31 March 2022 to identify relevant published studies. PubMed, EMBASE, CINAHL, and Google Scholar databases were used. Twenty-four studies met the inclusion criteria, and the mean age was 68 years. Localized and locally advanced diseases had relatively higher overall survival than metastatic diseases. In metastatic disease, the mean overall five-year survival was 42% which is shorter than the Asian population (61.9%).

Assessment of cisplatin-induced nephrotoxicity and its associated factors among cervical cancer patients in the leading tertiary hospital in Kenya.

INTRODUCTION: Cisplatin is the widely used antineoplastic agent in managing cervical cancer despite nephrotoxicity being a major concern. In addition, there was a paucity of data about the degree of nephrotoxicity due to cisplatin in the study setting. Therefore, this study aimed to investigate the prevalence of cisplatin nephrotoxicity among cervical patients. METHODS: A retrospective cross-sectional study was conducted at the Cancer Treatment Centre of Kenyatta National Hospital among 100 cervical cancer patients treated with a cisplatin regimen. Simple random sampling was employed to the recruit medical record of patients. This study used a data abstraction tool to extract the patients' relevant socio-demographic and clinical characteristics. The data were analysed using Statistical Package for Social Sciences version 25.0 software. Frequency tables and figures were used to present the findings of the study. Binary logistic regression analysis was used to determine factors associated with cisplatin nephrotoxicity. RESULTS: The study showed a mean age of 52.09 ± 10.44 years. The prevalence rate of cisplatin-induced nephrotoxicity in cervical cancer patients was 45%. Of these patients, 36% and 9% patients had grade 1 and 2 nephrotoxicities, respectively. Comorbidities (crude odd's ratio (COR) = 3.05, 95% confidence interval [CI] = 1.3-7.02, p = 0.011), hypertension (COR = 3.0, 95% CI = 1.1-7.8, p = 0.03), and more than three cycles of cisplatin treatment (adjusted odd's ratio = 4.5, 95% CI = 1.19-17.0, p = 0.027) were significant factors of nephrotoxicity. CONCLUSION: The prevalence of cisplatin-induced nephrotoxicity among cervical cancer patients was high in the study setting. Comorbidities, number of cycles and types of comorbidities were significant factors associated with cisplatin nephrotoxicity.

Treatment outcomes among human epidermal growth factor receptor 2 positive breast cancer patients: A systematic review.

BACKGROUND: The incidence of human epidermal growth factor receptor 2 (HER 2) positive breast cancers is rapidly rising worldwide. Although there have been many studies on HER 2 breast cancer treatment and management in recent years, there is a lack of comprehensive reports on the treatment outcomes and disparities within the available literature. Hence, this review aimed to determine the treatment outcomes and their associated factors among patients with HER2-positive breast cancer. METHODS: A computer-based systematic literature search was conducted using PubMed, EMBASE, and Google scholar databases of articles published from 2000 to 2020. The following key terms (HER 2 positive breast cancer, predictor, determinant, associated factor) and Medical Subject Headings (MeSH) terms (breast neoplasms, treatment outcome, and risk factors) were used to search the English language published articles. RESULTS: In most studies, trastuzumab was the most commonly used treatment regimen used in combination with chemotherapeutic agents. Generally, most of the studies (15 studies) showed that the overall survival outcome was relatively higher after treatment among HER2 positive breast cancer patients. Nonetheless, two studies showed that the absence of significant change in the overall survival despite adequate treatment was given to the study participants. In addition, three studies demonstrated a partial response after treating HER2-positive breast cancer patients. CONCLUSION: Generally, the overall survival outcome was relatively higher after treatment among HER2 positive breast cancer patients. The addition of trastuzumab in most of the studies has shown improvement in the overall survival and the disease-free survival rate of the study patients.

Drug-related problems and its associated factors among breast cancer patients at the University of Gondar Comprehensive Specialized Hospital, Ethiopia: A hospital-based retrospective cross-sectional study.

BACKGROUND: Breast cancer is the most frequently diagnosed cancer and the leading cause of cancer deaths among women worldwide. If untreated and undetected at the early stage, it causes death by spreading to distant organs. Despite various studies suggesting the high prevalence of drug-related problems among cancer patients, there was a paucity of data regarding the problems among breast cancer patients in our setting. Hence, this study was aimed to assess the drug-related problems among patients with breast cancer at the Oncology Unit of the University of Gondar Comprehensive Specialized Hospital. METHODS: A retrospective cross-sectional study was conducted at the Oncology Unit of the University of Gondar Comprehensive Specialized Hospital. The data were collected by retrospective reviewing medical records of 107 breast cancer patients. The data entry and analysis were done using SPSS version 20.0 statistical software. Descriptive statistics such as percent and frequency were used to summarize categorical variables of patients' characteristics. Univariable and multivariable binary logistic regression analyses were used to investigate the potential predictors of drug-related problems. A p-value of < 0.05 was considered statistically significant. RESULTS: A total of 203 drug-related problems were identified from 76 breast cancer patients, translating to a prevalence of 71.03%. Among the drug-related problems identified, adverse drug reaction (48.6%), need for additional drug therapy (45.8%), and non-adherence (32.7%) were the most prevalent. In the multivariable analysis, breast cancer patients who had concurrent co-morbidities were almost three times (AOR = 2.97, p = 0.035) more likely to experience drug-related problems as compared to those patients without co-morbidity. Moreover, those patients who had been treated with neoadjuvant chemotherapeutic regimens were 0.34 times less likely (crude odd ratio = 0.34, p = 0.023) to have drug-related problems as compared to patients treated with adjuvant chemotherapy regimens. CONCLUSION: The prevalence of drug-related problems was high in our setting. Adverse drug reactions, the need for additional drug therapy, and non-adherence were the most frequently occurring drug-related problems in the study setting. Neoadjuvant chemotherapy and the presence of co-morbidities were significant predictors of drug-related problems among breast cancer patients.

Factors affecting health-related quality of life among prostate cancer patients: A systematic review.

INTRODUCTION: Prostate cancer is recognized as the leading cause of malignancy-related incidence and mortality in the male population. The treatment regimens have long-term effects detrimental to the patient's quality of life. Hence, this review was aimed to determine the overall HRQOL and its associated among prostate cancer patients. METHODS: The review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. The databases searched were PubMed, Embase, Google Scholar and Cumulative Index to the Nursing and Allied Literature (CINAHL), which provided articles that were critically examined, yielding 52 studies that met the inclusion criteria for the systematic review. RESULTS: Out of 52 studies, 30 studies reported poor overall HRQOL in various domains after prostate cancer treatment. Contrastingly, 15 studies reported good overall quality of life after treatment. Among the various domains, sexual function was the most grossly affected functional score by the treatment modalities of prostate cancer. Nonetheless, seven studies showed that the absence of a significant change in the overall quality of life after treatment. According to the studies, older age, comorbidities, higher clinical stage, higher Gleason score, greater cancer severity, African American race, impaired mental health, neoadjuvant hormonal therapy and lower level of education were the major poor predictors of HRQOL among prostate cancer patients. CONCLUSION: The overall HRQOL in prostate cancer patients was generally poor in various functional domains after treatment. Among the various domains, sexual function was the most grossly affected functional score by the treatment modalities of prostate cancer.

Evaluation of the anti-diarrheal activity of the leaf extract of Croton macrostachyus Hocsht. ex Del. (Euphorbiaceae) in mice model.

BACKGROUND: Traditional healers in Ethiopia use a wide range of medicinal plants with antidiarrheal properties. Among these, Croton macrostachyus is one such plant claimed to have an antidiarrheal activity in Ethiopian folklore medicine. Previous studies showed that the crude extract is endowed with the claimed property. The present study was undertaken to further the claim by screening different fractions for the said activity so that it could serve as a basis for subsequent studies. METHODS: The fractions were obtained by successive extraction in soxhlet apparatus with solvents of different polarity (chloroform & methanol) followed by cold maceration of the deposit of the methanol fraction with distilled water. The antidiarrheal activity was evaluated using castor oil induced diarrheal model, charcoal meal test and anti-enteropooling test in mice. The test groups received various doses (300, 400, 500 mg/kg and an additional dose of 1000 mg/kg for the aqueous fraction) of the fractions, whereas positive controls received either Loperamide (3 mg/kg) or Atropine (5 mg/kg) and negative controls received vehicle (10 ml/kg). RESULTS: In the castor oil induced model, the chloroform (at all test doses) and methanol (at 400 & 500 mg/kg) fractions significantly delayed diarrheal onset, decreased stool frequency and weight of feces. The aqueous fraction was however devoid of significant effect at all the tested doses. Chloroform and methanol fractions produced a significant dose dependent decline in the weight and volume of intestinal contents while the aqueous fraction did not have a significant effect. All the fractions produced a significant anti-motility effect either at all doses (chloroform fraction) or at middle and higher doses (methanol and aqueous fractions). CONCLUSION: The present study demonstrated that the chloroform and methanol fractions possessed significant anti-diarrheal activity. Nevertheless, the aqueous fraction showed only significant anti-motility effect at the higher dose (1000 mg/kg) employed in the study.

An assessment of survival outcomes among ovarian cancer patients at the National and Referral Hospital in Kenya.

BACKGROUND: Ovarian cancer has been shown to have poor survival outcomes attributed to late presentation. In Kenya, information on the survival outcomes of ovarian cancer patients is scarce. Therefore, the objective of this study was to examine the survival outcomes among patients with ovarian cancer treated at Kenyatta National Hospital (KNH). AIMS: A hospital-based retrospective cohort study was performed at KNH to examine the survival outcomes of 112 ovarian cancer patients. The study employed a structured data abstraction tool to acquire patients' relevant socio-demographic and clinical characteristics from the patient's medical records. The data obtained were analyzed using SPSS version 29.0 statistical software. Kaplan-Meier and Cox regression analyses were used to determine the survival outcome and predictors of mortality among ovarian cancer patients, respectively. METHODS AND RESULTS: The mean age of the patients in this study was 51.28 ± 14.24 years. Most patients (59.8%) had evidence of distant metastasis during the follow-up period. One-third (33%) of patients were deceased. The mean-cancer-specific survival time among the study participants was 40.0 ± 3.0 months. The 5-year survival rate was 44%, with most patients experiencing disease progression during the last follow-up. Combination therapy (p < .001) was the only statistically significant predictor of mortality in ovarian cancer patients. CONCLUSION: The study found that the 5-year survival rate among ovarian cancer patients was poor, with most patients experiencing disease progression during the last follow-up period.

Health-related quality of life among patients with esophageal, gastric, and colorectal cancer at Kenyatta National Hospital.

BACKGROUND: Despite the advancement of modern treatment approaches, several studies indicated a diminished health-related quality of life (HRQoL) in patients with gastrointestinal cancer. However, there is insufficient data about the HRQoL of gastrointestinal cancer patients in Kenya. AIMS: The study aimed to investigate HRQoL and its determinants in gastrointestinal cancer patients at Kenyatta National Hospital. METHODS: A cross-sectional study was employed among 160 esophageal, 103 gastric, and 96 colorectal cancer patients. The patient list, identified by unique hospital identification numbers, was obtained from records. Eligibility was assessed based on predetermined criteria, and the hospital identification numbers were reshuffled. Study participants were then randomly selected daily during the data collection period. Data were collected using a researcher-administered European Organization for Research and Treatment of Cancer quality of life questionnaire. The data entry and analysis were carried out using Statistical Package for the Social Sciences 26.0 statistical software. A bivariate and multivariate binary logistic regression analysis was employed to investigate determinants of HRQoL at a 0.05 level of significance. RESULTS: Most esophageal (N = 118, 73.7%), gastric (N = 75, 72.8%), and colorectal (N = 72, 75%) cancer patients had poor overall HRQoL. In the social (p = .04) and cognitive (p = .02) domain of HRQoL, esophageal cancer patients had a significantly lower mean score as compared to gastric cancer patients. Colorectal cancer patients had the highest mean score in physical functioning (p = .01) as compared with gastric cancer patients. Nonetheless, gastric cancer patients had the highest mean score in emotional functioning domains of quality of life as compared to esophageal (p = .04) and colorectal (p < .001) cancer patients The study revealed a low mean HRQoL score in the majority of the symptom domains of quality of life. A statistically significant difference in all domains of HRQoL was not observed in various treatment modalities of gastrointestinal cancer. Advanced-stage (stages III and IV) and co-morbidities were significant determinants of poor HRQoL. CONCLUSIONS: The overall HRQoL of gastrointestinal cancer patients was poor. Advanced-stage cancer and co-morbidities were significant determinants of poor HRQoL. Therefore, intensification of routine monitoring of the disease and the treatments should be actively implemented to improve the HRQoL.

Assessment of survival outcomes among lung cancer patients at the National and Referral Hospital in Kenya.

INTRODUCTION: Lung cancer has a low overall survival rate linked to late diagnosis and metastasis. Unfortunately, comprehensive data within the African continent are limited due to the lack of a registry, low public awareness of lung cancer, financial constraints, and inadequate screening and treatment facilities. In addition, there was a lack of conclusive data in our setting. Therefore, this study aimed to assess survival outcomes among lung cancer patients at Kenyatta National Hospital. METHODS: A hospital-based retrospective cohort study was performed to examine the survival outcomes of 151 lung cancer patients. All eligible lung cancer patients diagnosed and treated in the facility between January 1, 2018, and December 31, 2020, were included. The patients were retrospectively followed from the date of primary cancer diagnosis until death or the last follow-up period. The Statistical Package for the Social Sciences (SPSS) version 20.0 statistical software was used to enter and analyze the data. Kaplan-Meier survival and Cox regression analysis were employed to determine median survival and predictors of mortality, respectively. RESULTS: The mean and median follow-time was 18.2 and 17.5 months, respectively. Most (98%) of the patients had non-small cell lung cancer. The 2-year survival rate was 66.7%, with 59.6% of patients having developed distant metastasis during the follow-up, while 25.1% were deceased. The median cancer-specific survival time among the study population was 18.0 ± 3.40 months. Cox regression analyses showed that patients with distant metastasis had five times more risk of dying (AHR: 4.74, 95% CI: 2.1-10.8, p < 0.001) than patients without distant metastasis. CONCLUSIONS: The overall two-year survival rate of lung cancer patients at the Kenyatta National Hospital was 66.7%, with most patients developed distant metastasis during the follow-up period. Distant metastasis was the only significant predictor of mortality among lung cancer patients in our setting.

Survival outcomes among colorectal cancer patients at Kenyatta National Hospital: A retrospective cohort study.

BACKGROUND: Colorectal cancer is a growing burden in Africa. However, survival for patients with colorectal cancer remains low in sub-Saharan African countries, with the poorest survival, particularly at a late stage at diagnosis. Despite this, there is a paucity of sufficient data about the survival outcomes of colorectal cancer patients in Kenya. AIMS: This study aimed to determine the survival outcomes among colorectal cancer patients at Kenyatta National Hospital. METHODS AND RESULTS: A retrospective cohort study was employed among 232 eligible medical records of colorectal cancer patients. Simple random sampling was used to select the medical records of the patients. The included medical records of the study participants were followed up retrospectively from the date of primary cancer diagnosis until the last visit to the hospital. All relevant data, such as sociodemographics, clinical characteristics, and outcome-measuring parameters, were recorded in the predesigned data abstraction tool by reviewing the documented clinical records of the patients. The data were entered and analyzed using International Business Machines (IBM) Statistical Package for the Social Sciences (SPSS) version 26 software. Mean, median, standard deviation, frequency tables, and figures were used to present the data. Kaplan Meier analyses were employed to determine survival outcomes. The mean age of the study participants was 54.1 ± 13.3 years, and the majority were males (126, 54.3%). Almost a third (34.1%) of patients had evidence of disease progression despite treatment in the follow-up period, with 7.8% showing no response to therapy and 23.6% experiencing new distant metastasis. The survival rate dwindled from the first year (87.9%) to the fifth year (45.4%), and the mortality rate was 22.8% CONCLUSION: There was a high mortality rate, disease progression, and distant metastasis in the last follow-up period suggesting the need to strengthen the healthcare system by ensuring access to prevention, early diagnosis, and optimal treatment of colorectal cancer.

Predictors of survival outcomes among patients with gastric cancer in a leading tertiary, teaching and referral hospital in Kenya.

INTRODUCTION: The incidence of gastrointestinal malignancies in Kenya is increasing, although there is a paucity of data on survival outcomes among gastric cancer patients. Hence, this study aimed to assess survival outcomes among adult gastric cancer patients at Kenyatta National Hospital. METHODS: A retrospective cohort study design was used to assess the survival outcomes among 247 gastric cancer patients. All medical records of adult (≥18 years) gastric cancer patients with complete medical records of diagnosis, stage of cancer, and treatment regimen in the study setting in the last 5 years (2016-2020) were included. A simple random sampling technique was employed to select the study participants. Data were collected using a data abstraction tool composed of socio-demographic and clinical characteristics. Survival outcomes were reported as the percentage of mortality, mean survival estimate, and mean cancer-specific survival. The data were entered and analyzed using version 20.0 SPSS statistical software. The mean survival estimates and predictors of mortality were computed using the Kaplan-Meier and Cox regression analysis. RESULTS: The study showed that 33.3% (64) had new distant metastasis, and 42.1% (104) had disease progression. Besides, the mortality rate was high (33.6%), and 14.6% and 7.7% of patients had complete and partial responses, respectively. The five-year survival was 32.7% among gastric cancer patients. Comorbidity (p = 0.014), advanced-stage diseases (p = 0.03), chemotherapy (p = 0.008), and gastrectomy (p = 0.016) were significant determinants of mortality. CONCLUSIONS: A significant proportion of patients had distant metastasis, disease progression, and a low five-year survival rate. Hence, early cancer-screening programs are indispensable to circumvent disease progression and improve survival outcomes.

Determinants of survival outcomes among esophageal cancer patients at a national referral hospital in Kenya.

Introduction: The overall 5-year survival rate for esophageal cancer patients in low- and middle-income countries was reported to be low, despite the availability of advanced treatments. Thus, this study aimed to assess determinants of survival outcomes among esophageal cancer patients in Kenya. Methods: A retrospective cohort study was employed among 299 adult esophageal cancer patients. The data were collected using a data abstraction tool consisting of patients' clinical characteristics and survival outcome measuring parameters. Statistical Package for the Social Sciences (SPSS) statistical software (version 20.0, IBM. USA) was used to analyze the data. The Kaplan-Meier and Cox regression analyses were used to determine the survival outcome and determinants of mortality, respectively. Results: The mortality rate was 43.1%, and 11.1% of patients demonstrated distant metastases in the follow-up period. Despite treatment, 20.1% had progressed disease, and 13.0% did not respond to treatment. Radiotherapy (AHR: 3.3, 95% CI: 1.4-7.8, p = 0.007), chemotherapy (AHR: 3.9, 95% CI: 1.2-6.1, p = 0.020), and chemoradiation (AHR: 5.6, 95%CI: 1.6-10.2, p = 0.006) were the significant determinants of survival in advanced stage (III and and IV) patients. Conclusions: There was a high mortality rate, disease progression, and nonresponse of esophageal cancer patients. Hence, it is essential to improve the survival of patients through early detection and timely initiation of the available treatment options.

Anticoagulation Management in Patients Receiving Warfarin at Private Cardiac Centers in Addis Ababa, Ethiopia.

Introduction: Anticoagulants are the cornerstone therapy for thromboembolism prevention and treatment. Warfarin is the frequently prescribed drug and remains the oral anticoagulant of choice in low- and middle-income countries, including Ethiopia. It is a narrow therapeutic index drug that needs high-quality anticoagulation monitoring with frequent international normalization ratio (INR) testing. Objective: The study aimed to assess anticoagulation management with warfarin among adult outpatients at two selected private cardiac centers in Addis Ababa, Ethiopia. Methods: A hospital-based retrospective study design that enrolled 374 patients receiving warfarin was employed at two private cardiac centres in Addis Ababa, Ethiopia. The time in the therapeutic range (TTR) was calculated using the Rosendaal method. The data were analyzed using Statistical Package for Social Science version 25. Results: The mean age of the patients was 57 years, and 218 (58.3%) participants were females. Out of 3384 INR tests, 1562 (46.5%) were within the therapeutic range and the mean percentage of TTR was 47.24%. Only 25.67% of the patients spent their TTR ≥ 65%. The present study revealed that dose adjustments were required 1764 times. In non-therapeutic INR values of 1764 that required warfarin dose adjustment, 59.7% of the doses were adjusted. About 262 (70.1%) of co-prescribed medications had interaction with warfarin. Sixty-four patients (17.11%) experienced bleeding events. Conclusion: Anticoagulation management with warfarin was suboptimal in private cardiac Addis Ababa, Ethiopia, private cardiac centers. Warfarin adjustment practice for nontherapeutic INR values was not minimal, and many patients encountered bleeding during their course of therapy.

Reliability and Validity of the Amharic Version of the Hill-Bone Adherence to High Blood Pressure Therapy Scale Among Ethiopian Hypertensive Patients.

Background: Hypertension is the leading cause of death from cardiovascular disease. Non-adherence to treatment and lifestyle modification are the key drivers of suboptimal blood pressure control and cardiovascular events. Objective: To assess the reliability and validity of the Amharic version of the Hill-Bone Adherence to High Blood Pressure Therapy Scale (HBTS) among Ethiopian hypertensive patients. Methods: A cross-sectional study was conducted among 294 hypertensive patients at two health facilities from 1st October to 30th December 2021 using the culturally adapted HBTS. Psychometric properties were assessed in terms of acceptability, internal consistency, construct validity, and predictive validity. Statistical Package for Social Sciences version 26 was used to perform statistical tests at a significance level of p-value <0.05. The Statistical Package for Social Sciences AMOS version 26 was used for the confirmatory factor analysis. Results: Cronbach of the 14-item HBTS was initially 0.801. After excluding one item from the appointment-keeping subscale, Cronbach of the modified 13-item HBTS was 0.806. The initial principal component analysis revealed four constructs for the 14-item and three for the 12-item with a total explained variance of 58.65% and 55.73%, respectively. The confirmatory factor analysis failed to fit the observed items with the latent subscales. The predictive validity test showed that the modified 12-item Amharic version was correlated (r= 0.118;p<0.043) with systolic blood pressure. Conclusion: The modified 13-item Amharic version of the HBTS is a reliable and valid tool with adequate psychometric properties. It can be used to assess adherence to antihypertensive medications in Amharic-speaking patients in Ethiopia.

Survival Outcomes Among Pancreatic Cancer Patients at Kenyatta National Hospital.

PURPOSE: Mortality from pancreatic cancer has risen fast in the past two decades in East Africa, including Kenya. However, there was a paucity of conclusive data about the survival of pancreatic cancer patients in the study setting. Hence, this study aimed to assess the survival outcomes of pancreatic cancer patients at Kenyatta National Hospital. METHODS: A hospital-based retrospective cohort analysis was used to evaluate the survival outcomes among pancreatic cancer patients treated in the study setting from 1 January 2015 to 31 December 2019. A total of 64 eligible pancreatic cancer patients were included in the study. In the pre-designed data abstraction tool, the data were collected by reviewing the medical records of the patients. The data were analyzed using the Statistical Package for the Social Sciences version 22 software. The mean survival time was estimated using Kaplan-Meier survival analysis. Cox regression analysis was employed to estimate the predictors of mortality among pancreatic cancer patients. RESULTS: The mean age of the study participants was 60.38 ± 12.61 years. Most of the patients had adenocarcinoma (96.9%) and were diagnosed at an advanced stage of the disease. The overall mean and median survival estimate for pancreatic cancer was 48.7 ± 9.7 and 39.0 ± 23.9 months, respectively. The present study showed that the overall survival rate of pancreatic cancer patients was 79.7%. CONCLUSION: The mortality rate of pancreatic cancer in the present study was 20%. The overall mean survival estimate for pancreatic cancer was 48.7 ± 9.7 months, and the majority had disease progression in the last follow-up period.
