Antimicrobial Use and Management of Childhood Diarrhea at Community Drug Retail Outlets in Eastern Ethiopia: A Matched Questionnaire-Based and Simulated Patient-Case Study.

Introduction: Antimicrobial agents have saved millions of lives worldwide. However, inappropriate use has become a global concern leading to the emergence and spread of antimicrobial resistance (AMR). In this regard, the dispensing practices of pharmacy professionals in the community drug retail outlets (CDROs) plays a central role. Therefore, this study was aimed to assess the knowledge and dispensing practices of pharmacy professionals in the management of childhood diarrhea in CDROs of Eastern Ethiopia. Methods: A community based cross-sectional study was conducted in 100 randomly selected CDROs in Eastern Ethiopia from 1 August to 30 September 2020. Data were collected with a structured questionnaire matched with a simulated patient case. Descriptive statistics were employed to summarize variables. Cohen's Kappa was analyzed to measure the degree of agreement between questionnaire-based and simulated patient-based methods. Binary logistic regression analysis was conducted to determine factors associated with inappropriate dispensing practice. Results: Majority of the participants were aged 25-34 years (median: 29 years). High proportion of them were male (65%) and had work experiences of two or more years. Majority (61%) of the professionals were knowledgeable about AMR. Out of 2886 scores, 745 scores were agreed on Cohen's Kappa interrater agreement scale with the overall percent agreement between the two methods being 26.0%. Besides, about 67% of dispensing practices to the simulated patient case was found inappropriate. On the multivariate analysis, insufficient knowledge of retailers on AMR was significantly associated with the inappropriate dispensing of antimicrobial agents. Conclusion: A considerable proportion of retailers had insufficient knowledge regarding the emergence and spread of AMR. Only a quarter of their questionnaire-based knowledge response agreed with simulated-patient-based actual practice, indicating weak agreement between the two methods and high level of inappropriate practice. Besides, insufficient knowledge of retailers was significantly associated with their inappropriate dispensing of antimicrobials.

Incidence and predictors of mortality among persons receiving second-line tuberculosis treatment in sub-Saharan Africa: A meta-analysis of 43 cohort studies.

BACKGROUND: Drug resistance remains from among the most feared public health threats that commonly challenges tuberculosis treatment success. Since 2010, there have been rapid evolution and advances to second-line anti-tuberculosis treatments (SLD). However, evidence on impacts of these advances on incidence of mortality are scarce and conflicting. Estimating the number of people died from any cause during the follow-up period of SLD as the incidence proportion of all-cause mortality is the most informative way of appraising the drug-resistant tuberculosis treatment outcome. We thus aimed to estimate the pooled incidence of mortality and its predictors among persons receiving the SLD in sub-Saharan Africa. METHODS: We systematically identified relevant studies published between January, 2010 and March, 2020, by searching PubMed/MEDLINE, EMBASE, SCOPUS, Cochrane library, Google scholar, and Health Technology Assessment. Eligible English-language publications reported on death and/or its predictors among persons receiving SLD, but those publications that reported death among persons treated for extensively drug-resistant tuberculosis were excluded. Study features, patients' clinical characteristics, and incidence and/or predictors of mortality were extracted and pooled for effect sizes employing a random-effects model. The pooled incidence of mortality was estimated as percentage rate while risks of the individual predictors were appraised based on their independent associations with the mortality outcome. RESULTS: A total of 43 studies were reviewed that revealed 31,525 patients and 4,976 deaths. The pooled incidence of mortality was 17% (95% CI: 15%-18%; I2 = 91.40; P = 0.00). The studies used varied models in identifying predictors of mortality. They found diagnoses of clinical conditions (RR: 2.36; 95% CI: 1.82-3.05); excessive substance use (RR: 2.56; 95% CI: 1.78-3.67); HIV and other comorbidities (RR: 1.96; 95% CI: 1.65-2.32); resistance to SLD (RR: 1.75; 95% CI: 1.37-2.23); and male sex (RR: 1.82; 95% CI: 1.35-2.44) as consistent predictors of the mortality. Few individual studies also reported an increased incidence of mortality among persons initiated with the SLD after a month delay (RR: 1.59; 95% CI: 0.98-2.60) and those persons with history of tuberculosis (RR: 1.21; 95% CI: 1.12-1.32). CONCLUSIONS: We found about one in six persons who received SLD in sub-Saharan Africa had died in the last decade. This incidence of mortality among the drug-resistant tuberculosis patients in the sub-Saharan Africa mirrors the global average. Nevertheless, it was considerably high among the patients who had comorbidities; who were diagnosed with other clinical conditions; who had resistance to SLD; who were males and substance users. Therefore, modified measures involving shorter SLD regimens fortified with newer or repurposed drugs, differentiated care approaches, and support of substance use rehabilitation programs can help improve the treatment outcome of persons with the drug-resistant tuberculosis.

One in Five Street Traditional Coffee Vendors Suffered from Depression During the COVID-19 Pandemic in Harar Town, Ethiopia.

BACKGROUND: The COVID-19 crisis has already resulted in an economic and labor market shock and a rise of informal work sectors. Being an informal job, traditional coffee vending can predispose women to a myriad of mental disorders. Therefore, this study was aimed to assess depressive symptoms during the COVID-19 pandemic and associated factors among street traditional coffee vendors in Harar town, Eastern Ethiopia. METHODS: A cross-sectional study was employed on 180 women engaged in street traditional coffee vending business in Harar town. Data were collected through a face-to-face interview using a Public Health Questionnaire and analyzed using SPSS version 20. Binary logistic regression was executed to identify factors associated with depression at a cut-off point of P < 0.05. RESULTS: The mean age of the study participants was 31.83 (±10) years. The majority of the participants were currently married (n = 77, 42.8%), attended primary education (n = 68, 37.8%), had a family member of four or more (n = 60, 33.3%), and had two years or less work experience (n = 123, 68.3%). Most of the study participants obtained COVID-19-related information from television (n = 125, 69.4%). The prevalence of depression was found to be 18.9%. Attending primary education (AOR: 0.34; 95% CI: 0.12, 0.98), attending secondary education or higher (AOR: 0.23; 95% CI: 0.07, 0.69), and having four or more family members (AOR: 2.81; 95% CI: 1.14, 6.92) were significantly associated with depression. CONCLUSION: One in five street traditional coffee vendors suffered from depression during the COVID-19 pandemic. Lower odds of being depressed were observed in those who attended a minimum of primary education. On the contrary, having a greater family size was associated with higher odds of being depressed. This finding will direct the government and other concerned bodies to be involved in the provision of psychological and material support for such informal workers during COVID-19.

Availability, pricing and affordability of essential medicines in Eastern Ethiopia: a comprehensive analysis using WHO/HAI methodology.

BACKGROUND: Access to essential medicines is a universal human right and availability and affordability are the preconditions for it. In line with the sustainable development goals, World Health Organization (WHO) has outlined a framework that assists the policy makers to improve access to essential medicines for universal health coverage by 2030. However, the availability and affordability of essential medicines remains suboptimal in several low-income countries. Therefore, this study was designed to investigate the availability, pricing and affordability of essential medicines in eastern Ethiopia. METHODS: A cross-sectional study design was employed to conduct this study. Public and private health facilities found in Eastern Ethiopia and which fulfilled criteria set forth by WHO/Health Action International (HAI) guideline and essential medicines listed on WHO/HAI guideline and essential medicine list of Ethiopia were included. Accordingly, 60 medicine outlets were selected based on the WHO/HAI standardized sampling methodology. A standardized data collection tools developed by WHO/HAI, with necessary modifications, was employed to collect the data. Median Price Ratio (MPR) was computed as a ratio of median local buyers' price to international buyers' reference price. The Mann-Whitney U test was employed to compare the median buyers' price between public and private health facilities. Kruskal-Wallis test was also run to explore the median price difference among all facilities. Treatment affordability was calculated based on the number of days of wage of the lowest-paid government employee of Ethiopia required to purchase the prescribed regimen. RESULTS: The overall percent availability of originator brand (OB) versions of essential medicines was found to be 3.6% (range: 0.0-31.7%), with the public and private sectors contributing 1.43% and 5.50%, respectively. The overall percent availability of lowest price generics (LPGs) was 46.97% (range: 1.7-93.3%) (Public: 42.5%; private: 50.8%). Only eight LPGs (16.0%) met the WHO target of 80%. The Mann-Whitney U test indicated that 64% drugs showed statistically significant median price difference between public and private settings (p < 0.05). The MPR value indicated that the median buyers' price of drugs in private sector were more than four times the international reference price in 30% of drugs. The percentage of unaffordable medicine were 72.09 and 91.84% for public and private facilities, respectively, with 79.17% of the medicines were unaffordable when both settings were combined. CONCLUSION: Only 16% of the surveyed medicines surpassed the WHO cut-off point of 80%. Nearly one-third of drugs in the private sector had a price of more than four times compared to the international reference prices. Moreover, four out of five drugs were found unaffordable when both settings were combined, demanded several days of wage of lowest paid government employee. This finding calls a prompt action from stakeholders to devise a strategy that help promote the access of essential medicines and rescue the struggling healthcare system of Ethiopia.

Expected Impacts of COVID-19: Considering Resource-Limited Countries and Vulnerable Population.

Coronavirus disease in 2019 emerged in Wuhan, Hubei Province, China, in December 2019. After a month, it was declared a global threat to public health. The effects of the pandemic could be socio-economic, undermining the health system and risking livelihoods. Vulnerability to this infection has been associated with underlying comorbidities such as hypertension, diabetes, coronary heart disease, chronic respiratory diseases, cancer, and compromised immune systems. Co-morbidity has been common to the elderly, the disabled, and the homeless. In addition, more severe coronavirus disease outcomes have been reported in older males than females. Nonetheless, multiple variables are related to the concept of cultural gender that should be taken into account as women in more affected sectors are economically disadvantageous and over-represented. Similarly, although children are not the face of this pandemic, calamity has a profound effect on their welfare, especially for those living in poor and inconvenient situations. Moreover, the economic influence could be profound and universal when viewed through a migration lens as it is exacerbating xenophobic and discriminatory treatment. Protection measures to mitigate the outbreak of a pandemic, such as social distancing, may reduce social support for certain categories relied on for their day-to-day activities. The mental health of people would definitely be affected by the additional psychosocial burden of the pandemic, particularly in vulnerable groups. Integrated approaches are therefore mandatory to assist these groups and contain the pandemic.

Drug-related problems and associated factors in Ethiopia: a systematic review and meta-analysis.

BACKGROUND: Drug-related problems (DRPs) can occur at any stages of medication use processes, and a single drug could be associated with multiple DRPs. Once happened, it adversely affects health outcomes. In Ethiopia, evaluation of the magnitude and factors associated with DRPs had not been attempted at the national level. METHOD: The literature search was conducted in the following databases; PubMed, Embase, Medline, and Google Scholar. The quality of the included studies was checked using Joanna Brigg's Institute (JBI's) checklist, and data were analyzed using Stata software (version 14.0). The pooled estimate of DRPs was computed by a Random effect model (DerSimonian-Laird method). Cochran's Q test (I2) statistic)), and Begg's correlation and Egger's regression test were assessed for heterogeneity and publication bias, respectively. RESULT: Overall, 32 studies with a total sample size of 7,129 were included in the review. The estimated pooled prevalence of DRPs was 70% [0.70 (95% CI 0.64-0.76; I2 = 97.6% p = 0.000)]. Polypharmacy (taking ≥ 5 drugs) [RR = 1.3], medical comorbidity [RR = 1.3], poor medication adherence [RR = 1.7], uncontrolled blood pressure [RR = 1.4], substance use [RR = 1.2], type 2 diabetes [RR = 1.8], significant drug interaction [RR = 1.33], and a negative medication belief [RR = 3.72] significantly influenced the occurrence of DRPs. CONCLUSION: The estimated national prevalence of DRPs in Ethiopia was high. Presence of medical comorbidity, using multiple drugs, significant drug interaction, poor medication adherence, uncontrolled blood pressure, type 2 diabetes, substance use and a negative belief about medication significantly influenced the occurrence of DRPs. Initiating and/or strengthening pharmaceutical care services at the health care facilities could lower the occurrence of DRPs. PROSPERO registration number CRD42020162329.

Polymyxin-induced nephrotoxicity and its predictors: a systematic review and meta-analysis of studies conducted using RIFLE criteria of acute kidney injury.

Polymyxins are last-resort antibiotics re-emerged to treat infections caused by multidrug resistant (MDR) and extensively drug-resistant (XDR) Gram-negative bacterial infections. However, polymyxin-associated nephrotoxicity has become the main safety concern. Therefore, we conducted this systematic review and meta-analysis on polymyxin-induced nephrotoxicity and its predictors using studies conducted based on the validated RIFLE (Risk, Injury, Failure, Loss of Function and End-stage renal disease) criteria of acute kidney damage. Literature search was carried out through visiting legitimate databases and indexing services including PubMed, MEDLINE (Ovid®), EMBASE (Ovid®), and Scopus to retrieve relevant studies. Following screening and eligibility evaluation, relevant data were extracted from included studies and analyzed using STATA 15.0 and Rev-Man 5.3. Inverse variance method with random effects pooling model was used for the analysis of outcome measures at 95% confidence interval. Besides, meta-regression, meta-influence, and publication bias analyses were conducted. A total of 48 studies involving 6,199 adult patients aged ≥ 18 years were included for systematic review and meta-analysis. The pooled incidence of polymyxin-induced nephrotoxicity was found to be 45% (95% CI: 41- 49%; I2 = 92.52%). Stratifying with RIFLE severity scales, pooled estimates of polymyxin-treated patients identified as 'risk', 'injury' and 'failure' were 17% (95% CI: 14-20%), 13% (95% CI: 11-15%), and 10% (95% CI: 9-11%), respectively. Besides, the pooled incidence of colistin-induced nephrotoxicity was about 48% (95% CI: 42-54%), whereas that of polymyxin B was 38% (95% CI: 32-44%). Likewise, colistin had 37% increased risk of developing nephrotoxicity compared to the polymyxin B treated cohorts (RR = 1.37, 95% CI: 1.13-1.67; I2 = 57%). Older age (AOR = 1.03, 95% CI: 1.01-1.05), daily dose (AOR = 1.46, 95% CI: 1.09-1.96), underlying diabetes mellitus (AOR = 1.81, 95% CI: 1.25-2.63), and concomitant nephrotoxic drugs (AOR = 2.31, 95% CI: 1.79-3.00) were independent risk factors for polymyxin-induced nephrotoxicity. Patients with high serum albumin level were less likely (AOR = 0.69, 95% CI: 0.56-0.85] to experience nephrotoxicity compared to those with low albumin level. Despite the resurgence of these antibiotics for the chemotherapy of MDR/XDR-Gram-negative superbugs, the high incidence of nephrotoxicity has become a contemporary clinical concern. Being elderly, high daily dose, having underlying diseases such as diabetes, and use of concomitant nephrotoxic drugs were independent predictors of nephrotoxicity. Therefore, therapeutic drug monitoring should be done to these patients to outweigh the potential benefits of polymyxin therapy from its risk.

Anti-Cancer Effects of Lycopene in Animal Models of Hepatocellular Carcinoma: A Systematic Review and Meta-Analysis.

INTRODUCTION: Globally, hepatocellular carcinoma (HCC) is the sixth most diagnosed cancer and the third important cause of cancer-related death. As there are only two targeted drugs for the treatment of advanced HCC-that merely extend survival by a few months-the need for alternative treatments is inevitable. Lycopene, a carotenoid that is known to be most abundant in red tomatoes and tomato-based products, has been investigated for its anticancer activity in various types of cancers including HCC. This review was conducted to evaluate the effects of lycopene on HCC from animal models to pave the way for further clinical studies. METHODS: Electronic databases and search engines including PubMed, EMBASE, and Google Scholar were searched for original records addressing the anticancer effect of lycopene in animal models of HCC. Data were extracted using a format prepared in Microsoft Excel and exported to Stata 15.0 for analyses. A meta-analysis was performed using a random-effects model at a 95% confidence level for the outcome measures: tumor incidence, number, and growth (tumor volume and size). The presence of publication bias between studies was evaluated using Egger's test and funnel plot. The study protocol was registered in the PROSPERO database with reference number: CRD42019159312. RESULTS: The initial database search yields 286 articles, of which 15 studies met the inclusion criteria. The characteristics of the included studies were a bit diversified. The studies involved a total of 644 animals (312 treatment and 332 control groups) and mice shared the majority (488) followed by rats (117) and ferrets (39). The meta-analysis showed that lycopene significantly reduced the incidence [RR 0.8; 95% CI 0.69, 0.92 (p=0.00); I2 = 30.4%, p=0.16; n=11], number [SMD-1.83; 95% CI -3.10, -0.57 (p=0.01); I2 = 95.9%, p=0.00; n=9], and growth [SMD -2.13; 95% CI -4.20, -0.04 (p=0.04); I2 = 94.6%, p=0.00; n=4] of HCC. CONCLUSIONS: Administration of lycopene appears to inhibit the initiation and progression of cancer in animal models of HCC. However, more controlled and thorough preclinical studies are needed to further evaluate its anti-HCC effects and associated molecular mechanisms.

Uncontrolled hypertension in Ethiopia: a systematic review and meta-analysis of institution-based observational studies.

BACKGROUND: Uncontrolled hypertension is one of the major risk factors of cardiovascular and cerebrovascular diseases. The prevalence of hypertension in Ethiopia is expected to reach up to 30%. The aim of this study was to determine the prevalence of uncontrolled hypertension among hypertensive patients on treatment in Ethiopia. METHODS: Electronic databases and search engines including EMBASE (Ovid), PubMed/Medline, and Google Scholar were searched for original records in the English language addressing hypertension control in Ethiopia from 2000 to 2018. Data were extracted using a format prepared in Microsoft Excel and exported to STATA 15.0 software for analyses. The study protocol is registered at PROSPERO with reference number ID: CRD42018116336. RESULTS: A total of 13 studies with 5226 hypertension patients were included for systematic review and meta-analysis. The pooled prevalence of uncontrolled hypertension in Ethiopia was 48% (95% confidence interval (CI): 36, 61%). The result of the sub-group analysis, based on the year of publications, revealed that the prevalence of uncontrolled BP was highest in 2016 (63%; CI: 60, 67%) and in 2015 (59%; CI: 53, 65%). Univariate meta-regression revealed that sampling distribution was not a source of heterogeneity for the pooled estimate as well as the sub group analysis. CONCLUSION: The prevalence of uncontrolled hypertension was high in Ethiopia. This alarming public health issue fuels the ever-increasing cardiovascular and cerebrovascular diseases. The ministry of health has to design a policy and implementation mechanisms to reduce uncontrolled hypertension prevalence and improve awareness on blood pressure control.

Self-Reported and Actual Involvement of Community Pharmacy Professionals in the Management of Childhood Diarrhea: A Cross-Sectional and Simulated Patient Study at two Towns of Eastern Ethiopia.

BACKGROUND: Role of community pharmacy professionals is observed in the prevention and treatment of diarrhea and the associated problem of dehydration in children. The aim of this study was to assess self-reported knowledge and actual practices of community pharmacy professionals toward the management of diarrhea in Harar town and Dire Dawa city administration. METHODOLOGY: Community-based cross-sectional study was conducted on community pharmacy professionals practicing in community drug outlets of the two towns. Structured questionnaires and simulated patient were used to collect data. RESULTS: A total of 105 community pharmacy professionals from 105 community pharmacies were invited, out of which 69.5% were men. Age was the most frequently taken history in both studies and none of the participants take history about weight of the child, medication history, and nutrition condition in the simulated study. Even though more than 90% of the participants reported to recommend oral rehydration salt (ORS) plus zinc, above 85% of them dispense antimicrobial agents for the simulated patient. Dose (96%), frequency (98%), how to prepare ORS (98%), and duration (98%) were the most frequently given information in the questionnaire survey. However, the simulated study revealed that information about common side effects and major interactions were not given to the patient. CONCLUSION: The study identified that there is a great difference between self-reported knowledge and actual practices on the management of childhood diarrhea in community pharmacies.
