Exploring coagulation parameters as predictive biomarkers of Plasmodium infection: A comprehensive analysis of coagulation parameters.

BACKGROUND: Malaria affects the intravascular environment, leading to abnormal coagulation activation, prolonged prothrombin time, and activated partial thromboplastin time. Despite the high prevalence of malaria in the study area, there has been little published research on the effects of Plasmodium infection on coagulation parameters. OBJECTIVE: The aim was to assess the effect of malaria on basic coagulation parameters among patients attending Dembia Primary Hospital and Makisegnit Health Center. METHODS: A cross-sectional study was carried out from January to March 2020. The study involved 120 participants. Blood specimens were collected, which were analyzed using a Huma Clot Due Plus analyzer. The collected data were entered into EpiData and exported to SPSS version 21 for analysis. Non-parametric statistical methods were employed to analyze the data. The results were considered statistically significant if the p-value was less than 0.05. RESULTS: Individuals infected with Plasmodium exhibit coagulation disorders with elevated levels of PT (Prothrombin Time), APTT (Activated Partial Thromboplastin Time), and INR (International Normalization Ratio) in comparison to healthy controls. The median PT, APTT, and INR values for infected cases were measured at 20.5 [8.6], 39.5 [17.9], and 1.8 [0.9], respectively, while healthy controls had measurements of 15.1 [2.5], 28.8 [8.3], and 1.3 [0.2] (p ≤ 0.001). The severity of coagulation disorders increased with an increase in parasitemia levels. The type of Plasmodium species present had a significant impact on PT and INR values (p ≤ 0.001), whereas APTT did not show any significant impact across the Plasmodium species (p > 0.05). CONCLUSION: The results of this study found that malaria has a substantial impact on various blood clotting parameters, including PT, APTT, and INR. Parasitemia severity is significantly associated with extended PT and INR, implying that the higher the parasitemia, the longer it takes for blood to clot. Furthermore, the study discovered that the PT and INR levels differed based on the type of Plasmodium species responsible for the infection.

Drug-related problems in Ethiopian public healthcare settings: Systematic review and meta-analysis.

Identification and prevention of drug-related problems have become the central role of patient-centered pharmacy practitioners. After the initiation of patient-oriented pharmacy service, many studies evaluating magnitude of drug-related problems at facility level in Ethiopia have been conducted, though the extent of the problem at a national level remains unknown. Hence, this systematic review and meta-analysis is undertaken with the aim of quantifying the prevalence of drug-related problems in Ethiopian public healthcare settings using Cipolle/Strand classification system. Electronic databases were searched including PubMed, EMBASE, Web of Science, MEDLINE and HINARI, Google Scholar and ResearchGate for both published and unpublished works. Data on study characteristics and outcomes were extracted using the format developed on Microsoft Excel. The primary measure was the pooled prevalence of drug-related problems. The meta-analysis was conducted using OpenMeta[Analyst].A total of 17 studies were included in this systematic review and meta-analysis. The pooled prevalence of drug-related problems of patients who experienced at least one drug-related problem during their therapy was found to be 69.4% (95% confidence interval: 61.5-77.4). The most frequently reported types of drug-related problems were "need for additional drug and "noncompliance," together accounting for more than half of the drug-related problems. The most frequently reported factors associated with drug-related problems were patients' age, polypharmacy, comorbidities and the number days of hospital stay.The prevalence of drug-related problems in Ethiopian public healthcare settings was found to be high. Inconsistent reporting of drug-related problems was observed across the studies. It is imperative to design and implement interventions aimed at reducing drug-related problems. Responsible stakeholders should adopt uniform drug-related problem classification approach to ensure uniform reporting of drug-related problems in Ethiopian healthcare settings.

COVID-19-Related Knowledge, Attitude and Practice Among Hospital and Community Pharmacists in Addis Ababa, Ethiopia.

PURPOSE: This study was launched to assess COVID-19-related knowledge, attitude and practice among hospital and community pharmacists in Addis Ababa, Ethiopia. METHODS: Self-administered questionnaire was distributed to pharmacists working in hospitals and community pharmacies by physically delivering the questionnaire to study subjects. Data collected were entered into and analyzed by IBM SPSS Statistics® Version 25. Binary logistic analysis was used to determine the association between independent and outcome variables. RESULTS: All 295 participants who completed the survey stated that they had heard about COVID-19. Almost all of the participants were aware of the causative agent, the clinical manifestations and the ways of transmission of COVID-19. Most participants (92.2%) identified elderly individuals as one of the high-risk groups for severe complications and death while 89.5% identified supportive therapy and life support as recommended management options to date. More than half (53.2%) of the respondents were found to have adequate knowledge about COVID-19. Among respondents, 89.8% had a positive attitude on the importance of following WHO recommendations in reducing the transmission of COVID-19. Only 9.8% had confidence in the capacity of healthcare facilities in the country to properly handle potential COVID-19 pandemic. Inadequate protective measures were taken to protect the staff from COVID-19 in the institutions of 70.2% of the participants. Among the WHO recommended prevention measures, hand washing was exercised by 97.3% of the study participants. CONCLUSION: The study findings confirmed that there is a high level of knowledge on each specific aspect of COVID-19 among the study participants. However, only about half of the participants had adequate knowledge about the disease. The pharmacists showed a predominantly positive attitude towards the importance of WHO recommendations and predominantly negative attitude towards the country's capacity to deal with the pandemic. The practice related to COVID-19 was inadequate at institutional level. Nevertheless, most of the pharmacists individually exercised self-protective measures against COVID-19. All stakeholders should work on ensuring the adequate supply of materials and services that aid in controlling the pandemic.

Evaluation of patient safety culture among community pharmacists in Ethiopia: A cross-sectional study.

OBJECTIVE: The study was aimed to explore patient safety culture of community pharmacists working in Dessie and Gondar towns, Northern Ethiopia. METHODS: A cross-sectional study was conducted from 1st to 31st March 2018. In this cross-sectional survey, the Pharmacy Survey on Patient Safety Culture (PSOPSC), developed by the Agency for Healthcare Research and Quality (AHRQ), was used to collect data. PSOPSC is a self-administered questionnaire. The questionnaire was distributed among staffs who work in community pharmacies of Dessie and Gondar towns. All staffs available on data collection period in the pharmacy were included. The Statistical Package for Social Science (SPSS) software version 25 was used to enter and analyze the data. RESULTS: A total of 120 participants were approached and completed the questionnaire. Results from the study showed that high positive response rate was demonstrated in the domains of "Teamwork" (90.2%) followed by physical space and environment (83.1%). On the other hand, the result also identified that there is an enormous problem related to mistake communication (44.8%) and work pressure (45%). In addition, significant difference of percent positive responses were obtained across towns and staff working hours. CONCLUSIONS: The patient safety culture of community pharmacists is appreciable especially with respect to their teamwork. Besides, urgent attention should be given to areas of weakness, mainly in the domain of "mistake communication" and "staffing and work pressure".

Self-Medication among Medical and Nonmedical Students at the University of Gondar, Northwest Ethiopia: A Cross-Sectional Study.

Despite having some benefits, self-medication increases risks such as unnecessary use of medication, extended duration of consumption, incorrect diagnosis, drug-drug interactions, and polypharmacy. Thus, the purpose of this study is to compare self-medication practice between medical and nonmedical students of the University of Gondar, Northwest Ethiopia. An institutional-based cross-sectional comparative study was conducted on medical and nonmedical students of the University of Gondar from March 25 to May 15, 2018. A comparative sample of 213 medical and 212 nonmedical students were enrolled in the study. Data were collected by physically visiting the students in their campuses, using a semistructured questionnaire. Of the participants with a history of medication use in the past 12 months, 64.5% practiced self-medication. The prevalence of self-medication was 59.7% among medical students and 69.0% among nonmedical students. "Knowing the treatment of the disease" was the most frequent reason behind self-medication. Analgesics/antipyretics were the most common categories of medications used, whereas headache was the predominant ailment for which the medications were used. Self-medication practice was found to be higher in the fifth year students and nonmedical students (p < 0.05). In conclusion, self-medication is common among students of the University of Gondar. Nonmedical students were more likely to have practiced self-medication as compared to medical students.

Community's extent of use and approval of extended pharmacy services in community pharmacies in Southwest Ethiopia.

BACKGROUND: The emergence of chronic diseases as major causes of disability and death has necessitated the introduction of new strategies to effectively address the ever-changing nature of public health problems. As a result, the role of community pharmacies in promoting public health is growing in recent years through the provision of extended pharmacy services. This study was conducted with the aim of assessing community's extent of use and approval of extended pharmacy services at community pharmacies in Bonga town, Southwest Ethiopia. MATERIALS AND METHODS: Community based cross-sectional study was conducted in Bonga town, Southwest Ethiopia, on households selected by systematic random sampling. Data was collected using semi-structured questionnaire. Data was collected by personally delivering questionnaires to respondents in selected households. Results of the study were described by frequency, mean and standard deviation (SD). Binary logistic analysis was performed to identify potential associations between dependent and independent variables. RESULTS: Out of 356 individuals included in the study, 58.4% recalled visiting community pharmacy premises during the previous six months. Out of these, 34.6% visited the community pharmacies to get extended pharmacy services. College educated participants were 19.4 times more likely to have used extended pharmacy services as compared to illiterate individuals whereas those who earn monthly income more than 5000 Ethiopian Birr were 3.6 times more likely than those with monthly income of 2000 Ethiopian Birr or less. Of the total participants, 91.3% approved the provision of extended pharmacy services in community pharmacies. CONCLUSION: The extent of community's use of extended pharmacy services at community pharmacies was found to be low. Nevertheless, majority of the study subjects approved the provision of extended pharmacy services at community pharmacies. Efforts to improve the practice of extended pharmacy service provision at community pharmacies should be made by all stake holders.

Knowledge and Awareness of Cervical Cancer and Human Papillomavirus among Female Students in an Ethiopian University: A Cross-sectional Study.

BACKGROUND: Cervical cancer is causing a huge burden in Sub-Saharan Africa (SSA). It mainly affects women in their young ages making female university students at risk of cervical cancer. Knowledge and awareness about cervical cancer and human papillomavirus (HPV) in SSA including Ethiopia is very poor. We aimed to assess the knowledge and awareness of cervical cancer and HPV in University of Gondar (UOG) medicine and health science female students. A cross-sectional study was done. METHODS: This study was conducted from April 1 to May 30, 2016 at UOG, College of Medicine and Health Sciences, Gondar, Northwest Ethiopia. Undergraduate female students were included in the study. A 14-item self-administered questionnaire was then provided to each of the participants to measure their level of knowledge and awareness about cervical cancer and HPV. RESULTS: A total of 267 female students participated in the study (mean age 20.58 ± 1.22). More than half of the participants (59.6%) did not know the main cause of cervical cancer, whereas just about a fifth of them (19.5%) identified HPV as the main cause of cervical cancer. As high as 83.9% of the participants did not know other causes of cervical cancer. Binary logistic analysis revealed that students from midwifery (adjusted odds ratios [AOR] = 14.14, P < 0.05), anesthesiology (AOR = 9.66, P < 0.05) and medicine (AOR = 5.84, P < 0.05) departments were associated with knowledge of the main cause of cervical cancer. CONCLUSIONS: Knowledge about cervical cancer and its causes were found to be inadequate among higher education female students. Hence, awareness about cervical cancer, causes and its prevention, importance of screening and vaccination should be promoted through university's campaign, curricular changes, and community and research projects.

Appropriateness of chronic asthma management and medication adherence in patients visiting ambulatory clinic of Gondar University Hospital: a cross-sectional study.

BACKGROUND: Although asthma cannot be cured, appropriate management can ensure adequate control of the disease, prevent disease progression and even reverse the illness, enabling people to enjoy good quality of life. Predisposing factors for inappropriate asthma management, including limited diagnostic options and inadequate supply of medications, are features of health institutions in developing countries like Ethiopia. This study was launched to determine the appropriateness of asthma management in patients visiting ambulatory clinic of the Gondar University Hospital. METHODS: Cross-sectional study was conducted on asthmatic patients who were on chronic follow-up at Gondar University Hospital. Data were collected by review of patients' medical records and through a semi-structured questionnaire. The Global Initiative for Asthma guideline was used as a reference for determining the  appropriateness of asthma management whereas the eight-item Morisky medication adherence scale (MMAS-8) was used to collect data on patients' adherence to asthma medications. RESULTS: The study participants' ages ranged from 20 to 80 years with a mean age of 49.3 ± 13.6 years. Mild asthma showed a slight predominance in frequency accounting for 38.7% of cases. Asthma management was found to be inappropriate in 52.0% of the patients. Inappropriateness of therapy is attributed to incorrect dosing of medications, addition of unnecessary medications and omission of necessary medications. Patients who had moderate asthma were more likely to receive appropriate treatment [AOR = 728: 63.2, 8386.06], whereas having a treatment regimen of beclomethasone with salbutamol was found to be predictor of inappropriate treatment [AOR = 0.004: 0.001, 0.07]. More than half (56.7%) of the study subjects reported to have high adherence to their medications. Having no formal education was a predictor of low adherence to asthma medications [AOR = 0.051: 0.003, 0.978] whereas, increased monthly income was found to have a positive association with adherence [AOR = 1.923: 1.037, 3.566]. DISCUSSION: High prevalence of inappropriate therapy in this study may be attributed primarily to limited accessibility of asthma medications, as 86% of the patients received medium dose beclomethasone with salbutamol for exacerbations despite being at different severity of asthma and level of control. CONCLUSION: The findings of the study showed more than half of asthmatic patients received inappropriate treatment. Nevertheless, a larger proportion of the patients claimed to be highly adherent to their medications.

Potential drug-drug interactions in inpatients treated at the Internal Medicine ward of Tikur Anbessa Specialized Hospital.

PURPOSE: Although the concomitant use of multiple drugs often increases therapeutic effectiveness, certain combinations result in unwanted drug-drug interactions (DDIs). Most interactions go unnoticed by physicians due to the absence of new clinical signs and symptoms, and because they often produce a worsening of already existing symptoms. Quantification of the occurrence of the potential DDIs is essential to prevent the harmful effects associated with interactions. This study was launched to assess the prevalence of potential DDIs in the Internal Medicine ward of Tikur Anbessa Specialized Hospital, Addis Ababa, Ethiopia. PATIENTS AND METHODS: Cross-sectional data were gathered from the medical charts of 252 randomly selected patients who were admitted to the Internal Medicine ward during August 23 to October 23, 2013, and exposed to at least two concomitant drugs. Potential DDIs were identified using Medscape Drug Interaction Checker. The data were analyzed using SPSS software. Logistic regression analysis was used to determine the presence of association between variables and p-value <0.05 was considered statistically significant. RESULTS: At least one potential DDI was found in 78.2% of the patients. The mean number of potential interactions per patient was 3.7±3.4. Out of the 719 potential interactions identified, 49.8% were pharmacokinetic type, 44.6% were pharmacodynamic and the remaining 5.6% were unknown mechanisms. Major potential DDIs accounted for 13.1% of the whole interactions; 53.5% were moderate interactions; and the remaining 33.4% were minor interactions. Ceftriaxone, cimetidine and heparin were the three most involved drugs in major potential interactions. Prescription of five or more concomitant drugs was associated with high risk of encountering potential DDIs. CONCLUSION: The findings of this study showed that the prevalence of potential DDIs among inpatients was high. Pharmacists should closely review drugs prescribed for patients and avoid dispensing combinations of drugs that may have serious DDIs.

Prevalence of anemia before and after initiation of highly active antiretroviral therapy among HIV positive patients in Northwest Ethiopia: a retrospective study.

BACKGROUND: Human immunodeficiency virus (HIV) associated anemia is common and it is a challenge for prognosis of HIV positive patients. It is stated in different literature that the prevalence of anemia due to HIV before highly active antiretroviral therapy (HAART) initiation is more prevalent than after HAART initiation. Thus this study aimed to assess anemia prevalence before and after initiation of HAART among HIV patients attending university of Gondar hospital from 2008 - 2013. METHODS: A retrospective study was conducted by collecting data from antiretroviral clinic of University of Gondar Hospital from January 1, 2008 to December 30, 2013. Data was collected by using data collection sheet which contains age, sex, regimen type, hematological parameters and CD4 cell count. Data were analyzed using SPSS version 20. In order to compare means paired t-test was used. P- Value < 0.05 was considered as significant. RESULTS: Prevalence of anemia before and after HAART initiation was 21.2% and 11.5% respectively. There is a significance difference in CD4 cell count, hemoglobin and hematocrit values on patients before and after HAART initiation (P < 0.001). Opportunistic infection and CD4 cell count were associated with prevalence of anemia before HAART initiation. CONCLUSION: There was a decline in the prevalence of anemia and increment of mean CD4 cell count among HIV infected patients after HAART initiation. HIV patients are recommended checking up their CD4 cell counts regularly and starting HAART when it is appropriate with regular follow-up.

Optimization of the Erbium:YAG laser for precise incision of ureteral and urethral tissues: in vitro and in vivo results.

BACKGROUND AND OBJECTIVES: Tissue damage during endoscopic treatment of urethral and ureteral strictures may result in stricture recurrence. The Erbium:YAG laser ablates soft tissues with minimal peripheral damage and may be a promising alternative to cold knife and Holmium:YAG laser for precise incision of urological strictures. STUDY DESIGN/MATERIALS AND METHODS: Optimization of the Er:YAG laser was conducted using ex vivo porcine ureteral and canine urethral tissues. Preliminary in vivo studies were also performed in a laparoscopic porcine ureteral model with exposed ureter. Laser radiation with a wavelength of 2.94 microm, pulse lengths of 8, 70, and 220 microseconds, output energies of 2-35 mJ, fluences of 1-25 J/cm2, and pulse repetition rates of 5-30 Hz, was delivered through 250-microm and 425-microm core germanium oxide optical fibers in direct contact with tissue. RESULTS: Ex vivo perforation thresholds measured 2-4 J/cm2, with ablation rates of 50 microm/pulse at fluences of 6-11 J/cm2. In vivo perforation thresholds were approximately 1.8 J/cm2, with the ureter perforated in less than 20 pulses at fluences greater than 3.6 J/cm2. Peripheral thermal damage in tissue decreased from 30 to 60 microm to 10-20 microm as the laser pulse length decreased from 220 to 8 microseconds. Mechanical tissue damage was observed at the 8 microseconds pulse duration. CONCLUSIONS: The Er:YAG laser, operating at a pulse duration of approximately 70 microseconds, a fluence greater than approximately 4 J/cm2, and a repetition rate less than 20 Hz, is capable of rapidly incising urethral and ureteral tissues with minimal thermal and mechanical side-effects.
