Background: Pain and inflammation are the major devastating health problems commonly treated with traditional medicinal plants in Ethiopia. Echinops kebericho M. (Asteraceae) is the one which is frequently used to treat pain and inflammation by traditional healers in Ethiopian folk medicine. However, the plant has not been scientifically evaluated for its traditionally claimed use. The present study aimed at the investigation of analgesic and anti-inflammatory activities of 80% methanol root extract of Echinops kebericho M. in mice model. Methods: Successive maceration was used as a method of extraction using solvents of increasing polarity: methanol and water. After extraction of the roots with 80% hydro methanol, the crude extract was evaluated for its peripheral and central analgesic activities using acetic acid-induced writhing test and hot plate method, respectively, while its anti-inflammatory activity was evaluated using carrageenan- and formalin-induced paw edema. The extract was evaluated at 100, 200 and 400 mg/kg doses. The positive control groups were treated with ASA 150 mg/kg for writhing test, morphine 10 mg/kg for hot plat method, indomethacin 25 mg/kg and diclofenac 10 mg/kg for paw edema tests and vehicle, distilled water (10 mL/kg) treated mice were assigned as negative controls. All treatment administrations were performed orally. Results: E. kebericho extract at all test doses showed statistically significant antinociceptive activity in both chemicals-induced peripheral and thermal-induced central pain in a dose dependent manner (p < 0.01 and p < 0.001). The greater analgesic activity was observed by the maximum dose of the extract (400 mg/kg) in both acetic acids-induced writhing test (57.84%) and hot plate method (69.40%). The effect of the extract was also statistically significant (p < 0.01 and p < 0.001) in both carrageenan and formalin-induced paw edema in dose dependent manner. Greater edema inhibition was observed by the highest dose (400 mg/kg) in both observations with the respective percentage values of 70.00% and 79.87%, respectively. Conclusion: In general, the data obtained from the present study elucidated that the extract possessed a significant analgesic and anti-inflammatory activities and recommended for further studies.

Diabetes mellitus (DM) is a group of metabolic diseases characterized by hyperglycemia resulting from defects in insulin secretion, insulin action, or both. Thus, this study aimed to assess the prevalence and factors associated with HM use among DM patients A hospital-based cross-sectional study was conducted on 395 diabetic patients visiting the diabetes care service of Debre Tabor General Hospitalfrom August 1 to September 28, 2020. Interview guided self-administered questionnaire was used for data collection. Out of 395 diabetic patients, 231(58.5%) participants were used herbal medicine. The most dominant herbal products used were M.stenoptela (53.2%), N. sativa (42.0%), Z. officinale (32.5%), A. sativum (20.8%), A. vera (13.4%), P.gracilis(10.4%), T.schimperi(7.5%), V. amygdalina (5.2%), T. foenumgraecum(3.5%),and D.penninervum(2.2%).The odds of HM use in female participants were 1.98 times (AOR=1.98, 95% CI=1.72, 3.25) higher compared to male participants. The odds of HM use among participants who develop DM complications were 1.77 times (AOR=1.77, 95% CI=1.03, 2.83) higher than in participants without DM complications. The odds of HM use among participants with a family history of DM were 2.89 times (AOR=2.89, 95% CI=1.42, 3.19) higher than in participants without a family history of DM. The prevalence of herbal medicine use among diabetic patients was high. Educational level, gender, residence, educational level, duration of DM, presence of DM complication, and family history of DMwere the independent predictors' of HM use.

Objective: Even though antibiotic resistance is one of the most serious threats to global public health, it is becoming more common due to inappropriate antibiotic prescribing patterns. Thus, the purpose of this study is to assess antibiotic prescribing patterns among inpatients at an Ethiopian comprehensive specialized hospital. Methods: An institutional-based cross-sectional study was used. During the study period, data were collected from the charts of admitted patients in selected wards of Debre Tabor comprehensive specialized hospital. The World Health Organization’s developed questionnaire and conventional antibiotic prescribing indicators were used to assess rational drug usage, with an emphasis on antibiotic prescribing trends. The data were analyzed using SPSS 25.0 statistical software. Results: For 861 patients admitted to medical and pediatric wards, a total of 1444 antibiotics were prescribed. Overall, 60.6% of inpatients were prescribed at least one antibiotic, with an average (mean ± SD) number of antibiotics prescribed per patient of 1.7 ± 1.6. During their hospital stay, patients were given antibiotics for an average (mean ± SD) of 6.4 ± 2.7 days. Furthermore, 83.3% of antibiotics were prescribed for therapeutic purposes, whereas 100% were provided for empiric purposes. Ceftriaxone was the most commonly administered antibiotic in the study settings (49.2%). During the study period, Debre Tabor comprehensive specialized hospital had access to 67.5% of key antibiotics. Conclusion: The antibiotic prescribing pattern in our study diverged from the World Health Organization-recommended guidelines. Furthermore, all antibiotics were given without a culture or sensitivity test in every case. Setting up an antibiotic stewardship program, introducing antibiotic use based on culture and sensitivity tests, and adopting institutional guidelines could all help to address this issue.

Background: Drug therapy in the elderly needs an emphasis on age‐related changes in drug pharmacokinetics and pharmacodynamics profile. Hospitalized elderly patients are at risk of more than one disease and polypharmacy associated with these; they are at risk of drug‐related problems. This study aimed to assess the role of clinical pharmacy on identifying and resolution of drug‐related problems among elderly patients admitted to medical ward of Northwest Ethiopia comprehensive specialized hospitals. Methods: A multicenter prospective observational study was conducted. A systematic sampling technique was used. The identified drug‐related problem was recorded and classified using Cipolle, and adverse drug reaction was assessed using Naranjo algorithm of adverse drug reaction probability scale, and Medscape was used for drug‐drug interaction. Data were analyzed by using STATA software version 14.1. Logistic regression was used, and results were reported as odds ratios (ORs) with 95% Confidence intervals with P value < 0.05 statistically significant. Result: A total of 389 study participants were included in the study. About 266 (68.4%) of the participants had at least a single drug‐related problem. About 503 drug‐related problems were identified with a mean of 1.32 (CI: 1.27‐1.36) drug‐related problem per patient. The three‐leading categories of drug‐related problems were dose too high 108 (21.5%), nonadherence 105 (20.9%), and adverse drug reaction 96 (19.1%). Alcohol use (AOR = 2.2, 95CI%: 1.23‐3.94), source of the drug (AOR = 2.85, 95CI%: 1.63‐4.98), length of hospitalization (AOR = 2.32, 95CI%: 1.37‐3.95), number of comorbidities (AOR = 1.48, 95CI%: 1.09‐1.99), and polypharmacy (AOR = 3.06, 95CI%: 1.72‐5.46) were important risk factors for drug‐related problems. From the intervention provided, 84.7% were accepted by prescribers. Among the total drug‐related problems 67.4% of the problem was totally solved. Conclusion: This study revealed that DRPs were high among elderly patients admitted to medical ward of Northwest Ethiopia. Comorbidity, length of hospitalization, ploy‐pharmacy, payer, and alcohol drinker were more likely to developed drug‐related problems. Treatment optimizations were also done by clinical pharmacists and interventions were well accepted by prescribers.

A key issue for persons with leprosy-, lymphatic filariasis- and podoconiosis-related disabilities is the life-long need to practice self-management routines. This is difficult to sustain without regular encouragement and support of others. Family-based support may be a sustainable and feasible strategy to practice self-management routines. This proof of concept study aimed to develop and pilot a family-based intervention to support prevention and self-management of leprosy, lymphatic filariasis and podoconiosis-related disabilities in Ethiopia. We used a quasi-experimental pre/post intervention study design with a mixed methods approach. The study population included persons affected by leprosy, lymphatic filariasis and podoconiosis and their family members. All persons affected had visible impairments due to their condition. We collected physical impairment outcomes, data on activity limitations, stigma and family quality of life using the SALSA scale (range 0–80), the SARI stigma scale (range 0–63) and the Beach Centre Family Quality of Life scale (range 0–125) and conducted in-depth interviews and focus group discussions. Quantitative data were analysed using paired t-tests, unequal variances t-tests, linear regression and binary logistic regression. Qualitative data were coded using open, inductive coding and content analysis. The family-based intervention consisted of self-management of disabilities, awareness raising and socio-economic empowerment. The intervention was delivered over several monthly group meetings over the course of several months. A total of 275 (100%) persons affected attended at least one session with a family member, and 215 (78%) attended at least three sessions. There was no significant improvement in eye and hand problems after the intervention. However, foot and leg impairments, number of acute attacks, lymphedema and shoe wearing all significantly improved at follow-up. In addition, family quality of life significantly improved from 67.4 at baseline to 89.9 at follow-up for family members and from 76.9 to 84.1 for persons affected (p<0.001). Stigma levels significantly decreased from 24.0 at baseline to 16.7 at follow-up (p<0.001). Activity levels improved, but not significantly. This proof of concept study showed that the family-based intervention had a positive effect on impairments and self-management of disabilities, family quality of life and stigma. We recommend a large-scale efficacy trial, using a randomised controlled trial and validated measurement tools, to determine its effectiveness and long-term sustainability.

A peptic ulcer is described as the rupture of the mucosal integrity of the stomach, the duodenum, and, in certain cases, the lower esophagus as a result of contact with chloridopeptic secretions. The two most common kinds of peptic ulcer disorders are referred to as “gastric ulcer” and “duodenal ulcer.” The name is derived from the location of the ulceration. Despite the promise of a wide range of antiulcer treatments, these therapies are associated with several adverse reactions, including hypersensitivity, arrhythmia, impotence, gynecomastia, galactorrhea, hematological abnormalities, and kidney disease, which are intolerable for many patients. Nowadays, there is a lot of emphasis on finding new and innovative agents. As a result, herbal medicines are commonly utilized in circumstances when drugs are used for long periods and are also cost-efficient, effective, and readily available. In this review paper, a total of 82 medicinal plants have been identified and reported for their use in the treatment of peptic ulcer disease. The majority of these medicinal plants are widely used throughout Ethiopia. However, only the safety and efficacy of Plantago lanceolata, Osyris quadripartita, Rumex nepalensis, Cordia africana, Croton macrostachyus, and Urtica simensis have been scientifically studied in animal models. Despite this, many medicinal plants’ pharmacological effects and chemistry have not been well studied scientifically. As a result, further bioactive compound characterization, efficacy, mechanism of action evaluation, and toxicity evaluation of medicinal plants should be carried out. A study that can improve the documentation of indigenous knowledge and contribute to drug development and future self-reliance is also recommended.
