Modelling the current and future distribution potential areas of Peperomia abyssinica Miq., and Helichrysum citrispinum Steud. ex A. Rich. in Ethiopia.

BACKGROUND: The aim of this study is to investigate how climate change influences the distribution of economically and environmentally important species of P. abyssinica and H. citrispinum in Ethiopia. The species distribution modeling intends to forecast species' ecological niche ranges and habitat suitability by employing a variety of environmental parameters as predictors, which is vital for conservation planning and restoration success. Six representative concentration pathways (RCP 2.6, 4.5, and 8.5 for the years 2050 and 2070) with the same resolution of 2.5 min that shows the emission scenarios were used for the prediction. To predict the current and future distributions of H. citrispinum and P. abyssinica 56 and 45 occurrence records from National Herbarium, Addis Ababa University, GBIF, and available literatures were used respectively. RESULTS: The MaxEnt model predicted habitat suitability for H. citrispinum species with an Area Under Curve (AUC) value of 0.961 ± 0.027, and 0.809 ± 0.045 for P. abyssinica, indicating excellent discriminatory ability or accuracy under the current climate scenario. The Future distribution of suitable habitat for both H. citrispinum and P. abyssinica plant species was accurately predicted with AUC values of 0.960 ± 0.017 and 0.780 ± 0.35, respectively under future climatic scenarios. The jackknife test result indicates that environmental variables such as topographic position index (92.5%), precipitation of the driest quarter (3%) and precipitation in the coldest quarter (1.8%) are associated with the distributions of H. citrispinum, while topographic position index (36.6%), precipitation of driest quarter (21.4%), precipitation of warmest quarter (16.2%) and precipitation seasonality (13.9%) were found to be limiting environmental variables for P. abyssinica under current and future climatic conditions in Ethiopia. The prediction map and interception calculation for both present and projected (in the 2050s and again in the 2070s) climate change scenarios indicate significant habitat loss, decreased, and fragmentation under all RCPs (2.6, 4.5, and 8.5) scenarios for P. abyssinica while habitat gain, and increasing for H. citrispinum in Ethiopia. CONCLUSIONS: Topographic position index (TPI) is the most impactful predictor variable on the distribution of the two species. Consequently, potentially habitable areas (with diverse aspects and slopes) are increasing for H. citrispinum while decreasing for P. abyssinica.

Lidocaine versus propofol administration on the attenuation of hemodynamic responses during extubation in the adult elective surgical patient: A prospective cohort.

BACKGROUND: Tracheal extubation is the process of removing a tube from the trachea. It is associated with an increase in heart rate, blood pressure, intracranial pressure, intraocular pressure, coughing, bronchospasm, laryngospasm, and bleeding. Many techniques, as well as drugs, have been attempted for attenuation of the airway and cardiovascular responses. Propofol and lidocaine are widely available drugs in resource-limited settings even though their relative effectiveness for smooth extubation is not well established. OBJECTIVES: To assess the effectiveness of intravenous lidocaine and propofol on the attenuation of extubation-induced hemodynamic responses in the adult elective surgical patient from November 01, 2019, to February 30, 2020, at Asella teaching and referral hospital, Ethiopia. METHODS: Institutional-based prospective observational cohort study design was conducted on 72 ASA I patients who underwent elective surgery. The study participants were allocated into three groups equally based on anesthetists' extubation plan; Group P, 0.5 mg/kg propofol, group L, 1.5 mg/kg lidocaine administered 2 min before extubation and group C was a control group. Data were analyzed by SPSS version 20 after the normality of the data was checked by the Shapiro Wilk test. One-way ANOVA followed by a Tukey posthoc test has been employed to find the pair-wise significance and a p-value of <0.05 was considered as statistically significant. RESULTS: A demographic status and clinical characteristics of the patient were comparable between groups with p-values of >0.05. After extubation; heart rate, systolic, diastolic, and mean arterial blood pressure were decreased significantly in groups of propofol and lidocaine within 10 min. Propofol shows better results in maintaining stable systolic blood pressure up to 3 min, while heart rate, diastolic, and mean arterial pressure were maintained stable up to 5 min after extubation (p = 0.001). CONCLUSIONS: 0.5 mg/kg propofol or 1.5 mg/kg lidocaine might help to attenuate extubation induced hemodynamic responses.

Factors associated with enrollment for community-based health insurance scheme in Western Ethiopia: Case-control study.

INTRODUCTION: Modern health services utilization in developing countries has continued low. Financial shortage to access health-care services might be averted by stirring from out-of-pocket payment for health care at the time of use. The government of Ethiopia; depend greatly on foreign aid (50%) and out-of-pocket payments (34%) to fund health services for its population. This study was aimed to identify factors associated with households' enrollment to CBHI scheme membership. METHODS: Case-control study design was conducted from May 18-July 27, 2019 among 332 participants (166 enrolled and 166 non-enrolled to CBHI scheme). Simple random sampling technique was used to select the study participants. Bi-variable and multivariable logistic regression model were fitted to identify factors associated with enrollment to community based health insurance. Adjusted odds ratio (AOR) with 95% CI was used to report association and significance was declared at P<0.05. RESULT: A total of 332 (100% response rate) were involved in the study. Educational status (College and above, AOR = 3.90, 95%CI; 1.19, 12.75), good awareness about CBHI scheme (AOR = 21.595, 95% CI; 7.561, 61.681), affordability of premium payment (AOR = 3.403, 95% CI; 5.638-4.152), wealth index {(Poor, AOR = 2.59, 95%CI; 1.08, 6.20), (Middle, AOR = 4.13, 95%CI; 1.11, 15.32)} perceived health status (AOR = 5.536; 95% CI; 1.403-21.845), perceived quality of care (AOR: 21.014 95%CI; 4.178, 105.686) and treatment choice (AOR = 2.94, 95%CI; 1.47, 5.87) were factors significantly associated with enrollment to CBHI. CONCLUSION: Enrolment to CBHI schemes is influenced by educational level, awareness level, affordability of premium, wealth index, perceived health status, perceived quality of care and treatment choice. Implementation strategies aimed at raising community awareness, setting affordable premium, and providing quality healthcare would help in increasing enrollment of all eligible community groups to the CBHI scheme.
