Introduction Idiopathic pulmonary fibrosis (IPF) is an orphan disease characterized by progressive loss of lung function resulting in shortness of breath and often death within 3–4 years of diagnosis. Repetitive lung injury in susceptible individuals is believed to promote chronic oxidative stress, inflammation, and uncontrolled collagen deposition. Several preclinical and retrospective clinical studies in IPF have reported beneficial outcomes associated with the use of proton pump inhibitors (PPIs) such as esomeprazole. Accordingly, we sought to investigate molecular mechanism(s) by which PPIs favorably regulate the disease process. Methods We stimulated oxidative stress, pro-inflammatory and profibrotic phenotypes in primary human lung epithelial cells and fibroblasts upon treatment with bleomycin or transforming growth factor β (TGFβ) and assessed the effect of a prototype PPI, esomeprazole, in regulating these processes. Results Our study shows that esomeprazole controls pro-inflammatory and profibrotic molecules through nuclear translocation of the transcription factor nuclear factor-like 2 (Nrf2) and induction of the cytoprotective molecule heme oxygenase 1 (HO1). Genetic deletion of Nrf2 or pharmacological inhibition of HO1 impaired esomeprazole-mediated regulation of proinflammatory and profibrotic molecules. Additional studies indicate that activation of Mitogen Activated Protein Kinase (MAPK) pathway is involved in the process. Our experimental data was corroborated by bioinformatics studies of an NIH chemical library which hosts gene expression profiles of IPF lung fibroblasts treated with over 20,000 compounds including esomeprazole. Intriguingly, we found 45 genes that are upregulated in IPF but downregulated by esomeprazole. Pathway analysis showed that these genes are enriched for profibrotic processes. Unbiased high throughput RNA-seq study supported antifibrotic effect of esomeprazole and revealed several novel targets. Conclusions Taken together, PPIs may play antifibrotic role in IPF through direct regulation of the MAPK/Nrf2/HO1 pathway to favorably influence the disease process in IPF.

Background: The beneficial outcome associated with the use of proton pump inhibitors (PPIs) in idiopathic pulmonary fibrosis (IPF) has been reported in retrospective studies. To date, no prospective study has been conducted to confirm these outcomes. In addition, the potential mechanism by which PPIs improve measures of lung function and/ or transplant-free survival in IPF has not been elucidated. Methods: Here, we used biochemical, cell biological and preclinical studies to evaluate regulation of markers associated with inflammation and fibrosis. In our in vitro studies, we exposed primary lung fibroblasts, epithelial and endothelial cells to ionizing radiation or bleomycin; stimuli typically used to induce inflammation and fibrosis. In addition, we cultured lung fibroblasts from IPF patients and studied the effect of esomeprazole on collagen release. Our preclinical study tested efficacy of esomeprazole in a rat model of bleomycin-induced lung injury. Furthermore, we performed retrospective analysis of interstitial lung disease (ILD) databases to examine the effect of PPIs on transplant- free survival. Results: The cell culture studies revealed that esomeprazole controls inflammation by suppressing the expression of pro-inflammatory molecules including vascular cell adhesion molecule-1, inducible nitric oxide synthase, tumor necrosis factor-alpha (TNF-α) and interleukins (IL-1β and IL-6). The antioxidant effect is associated with strong induction of the stress-inducible cytoprotective protein heme oxygenase-1 (HO1) and the antifibrotic effect is associated with potent inhibition of fibroblast proliferation as well as downregulation of profibrotic proteins including receptors for transforming growth factor β (TGFβ), fibronectin and matrix metalloproteinases (MMPs). Furthermore, esomeprazole showed robust effect in mitigating the inflammatory and fibrotic responses in a murine model of acute lung injury. Finally, retrospective analysis of two ILD databases was performed to assess the effect of PPIs on transplant-free survival in IPF patients. Intriguingly, this data demonstrated that IPF patients on PPIs had prolonged survival over controls (median survival of 3.4 vs 2 years). Conclusions: Overall, these data indicate the possibility that PPIs may have protective function in IPF by directly modulating the disease process and suggest that they may have other clinical utility in the treatment of extra-intestinal diseases characterized by inflammatory and/or fibrotic phases.

Background: Delays seeking care worsen the burden of tuberculosis and cost of care for patients, families and the public health system. This study investigates costs of tuberculosis diagnosis incurred by patients, escorts and the public health system in 10 districts of Ethiopia.Methods: New pulmonary tuberculosis patients > or = 15 years old were interviewed regarding their health care seeking behaviour at the time of diagnosis. Using a structured questionnaire patients were interviewed about the duration of delay at alternative care providers and the public health system prior to diagnosis. Costs incurred by patients, escorts and the public health system were quantified through patient interview and review of medical records.Results: Interviews were held with 537 (58%) smear positive patients and 387 (42%) smear negative pulmonary patients. Of these, 413 (45%) were female; 451 (49%) were rural residents; and the median age was 34 years. The mean (median) days elapsed for consultation at alternative care providers and public health facilities prior to tuberculosis diagnosis was 5 days (0 days) and 3 (3 days) respectively. The total median cost incurred from first consultation to diagnosis was $27 per patient (mean = $59). The median costs per patient incurred by patient, escort and the public health system were $16 (mean = $29), $3 (mean = $23) and $3 (mean = $7) respectively. The total cost per patient diagnosed was higher for women, rural residents; those who received government food for work support, patients with smear negative pulmonary tuberculosis and patients who were not screened for TB in at least one district diagnostic centers.Conclusions: The costs of tuberculosis diagnosis incurred by patients and escorts represent a significant portion of their monthly income. The costs arising from time lost in seeking care comprised a major portion of the total cost of diagnosis, and may worsen the economic position of patients and their families. Getting treatment from alternative sources and low index of suspicion public health providers were key problems contributing to increased cost of tuberculosis diagnosis. Thus, the institution of effective systems of referral, ensuring screening of suspects across the district public health system and the involvement of alternative care providers in district tuberculosis control can reduce delays and the financial burden to patients and escorts.

- Abstract
Background: School-aged children (SAC) have an increased risk to contract malaria and play a major role in its transmission dynamics. However, their malaria prevention experience is poor. Thus, the effect of malaria prevention education (MPE) on bed net utilization, treatment seeking from a health facility and cumulative incidence of malaria was evaluated in Southern Ethiopia., Methods: A two arm cluster randomized controlled trial was conducted by recruiting 2038 SAC from 32 schools. Structured questionnaire was used to collect data on socio-demographic, economic, bed net ownership, bed net utilization, whether the participated child suffered from malaria and has got treatment from a health facility. Generalized mixed effect logistic regression using school as random variable was used to assess the effect of the intervention on the outcome variables., Results: The ownership of bed net in households of the control and intervention schools was similar respectively with 84.6 and 88.6% (Crude Odds Ratio (COR): 1.5; 95%CI: 0.5-4.8). The percentage of SAC slept under the bed net the night before the survey was also similar (55.1% versus 54.0%); COR:1.04; 95%CI: 0.5-2.4). Bed net utilization was affected by household size to the bed net ratio ≤ 2 (Adjusted Odds Ratio (AOR) = 1.6; 95%CI:1.3-2.1), bed net utilization at baseline of the study (AOR = 2.3; 95%CI:1.5-3.6), and history of malaria attack in the last twelve months (AOR = 1.3; 95%CI:1.01-1.8). Reported cumulative incidence of malaria and treatment seeking from a health facility by SAC was similar between intervention and control arms: -2.1% (COR = 0.8; 95%CI: 0.5-1.5) and 9.6% (COR = 1.4; 95%CI: 0.4-4.3) respectively. The reported incidence of malaria was affected by altitude (AOR = 0.5; 95%CI: 0.3-0.8), low and medium wealth index (AOR = 0.7; 95%CI: 0.5-0.96 and AOR = 0.7; 95%CI: 0.5-0.98), adequate bed net number for household members (AOR = 0.7; 95%CI:0.5-0.9) and bed net utilization (AOR = 1.3; 95%CI:1.1-1.8)., Conclusions: MPE had no significant effect on the use of malaria prevention measures considered, treatment seeking from a health facility and reported cumulative incidence of malaria though bed net use was associated with malaria incidence. Before organizing any health education program, sustainable implementation efforts have to be warranted especially in SAC, a neglected but relevant vulnerable and reservoirs., Trial Registration: Pan African Clinical Trials Registry PACTR202001837195738, registered 21/01/2020., (© 2023.

- Abstract
Background: Globally, men who have sex with men (MSM) and transgender women (TGW) encounter many challenging experiences when accessing health services compared to the general population. Stigma, discrimination, and punitive laws against same-sex relationships in some sub-Saharan African countries have made MSM and TGW more prone to depression, suicidal ideation, anxiety disorders, substance abuse, non-communicable diseases, and HIV. None of the prior studies in Rwanda on MSM and TGW had explored their lived experience in accessing health services. Accordingly, this study aimed at exploring the healthcare-seeking experiences of MSM and TGW in Rwanda., Methods: This study utilized a qualitative research method employing a phenomenological design. Semi-structured in-depth interviews were conducted with 16 MSM and 12 TGW. Participants were recruited via purposive and snowball sampling approaches in five districts in Rwanda.", Results: Data were analyzed using a thematic analysis approach. Three main themes emerged from the study: (1) The healthcare experiences of MSM and TGW were generally dissatisfactory, (2) MSM and TGW hesitated to seek care unless they were severely ill, (3) MSM and TGW's perspectives on how to improve their health-seeking behavior., Conclusion: MSM and TGW in Rwanda continue to face negative experiences within the healthcare delivery settings. These experiences include mistreatment, refusal of care, stigma, and discrimination. Provision of services for MSM and TGW and On-the-job cultural competence training in the care of MSM and TGW patients is needed. Including the same training in the medical and health sciences curriculum is recommended. Furthermore, awareness and sensitization campaigns to improve the understanding of the existence of MSM and TGW and to foster acceptance of gender and sexual diversity in society are necessary., (© 2023.

- Abstract
Background: Household food insecurity is a state in which household members experienced limited or uncertain physical and economic access to safe, plenty, and healthy food to meet the dietary needs for a fruitful, healthy, and active life. Food insecurity continues to be a major development and public health problem across the globe, having adverse consequences. This study was done to assess household food insecurity and to explore coping strategies in Kedida Gamela District, Southern Ethiopia., Method: A cross-sectional study complemented with the qualitative inquiry was carried-out from August to November 2020. Multistage sampling was used to select study subjects. A total sample of 597 households was selected randomly using up to date family folder list in the district as a sampling frame. For the qualitative study, 16 food-insecure households were selected randomly from food in secured households. Quantitative data were entered using Ep-Data 3.1 and exported to SPSS 20 for analysis. Bivariate analysis was carried out to see the crude association between each independent variable and outcome variable. P-value < 0.05 and 95%CI for adjusted odds ratios (AOR) were used to declare the significance of the associations. The qualitative data were analyzed using thematic analysis., Result: The findings of this study showed that 76% of the households were food insecure. Being female-headed households [AOR: 2.82:CI(1.10, 7.24)], absence of formal education [(AOR: 9.75:CI (3.7, 11.31)], lack of engagement in non-farm farm activities [(AOR; 3.30: CI (1.86, 5.96)], absence of credit service [AOR:4.04; C I (2.11,7.73)], presence of dependent household members [AOR: 3.47;(2.91,6.34)], poorest wealth status [AOR;9.86:CI (3.72, 15.85)] were factors significantly associated with food insecurity of the households. Food insecure households employed different coping strategies with the respective level of food insecurity., Conclusion: The findings of this study indicated that household food insecurity was higher in the study area. Moreover, sex, educational status, wealth status of the households; engagement of households in off/non-farm farm activities, credit service, and active and inactive labor force were significantly associated with household food insecurity. Food insecure households practice different coping strategies with respective food insecurity levels from the less severe strategy of eating inedible, fewer-quality foods to the most severe of migrating and begging for food. Planning and exhaustively implementing sustainable food security programs should get due attention., (© 2023. The Author(s).)

- Abstract
Background: To date, global healthcare spending becomes a primary concern, and pharmaceutical costs are the main drivers. The issue is more pressing in developing countries like Ethiopia. However, there is a scantiness of comprehensive data on inventory control practices in health facilities. This study, therefore, aimed to assess the criticality, financial value, and consumption patterns of pharmaceuticals using inventory matrix analyses and explore the related challenges., Methods: A cross-sectional study supplemented with qualitative assessments was carried out from December 2020 to January 2021 in public health facilities. Three hospitals and 14 health centers were proportionally selected using a simple random sampling technique. Self-administered questionnaires and review of logistics documents and databases like Dagu-Facility were used to obtain the quantitative data. The data were analyzed using excel spreadsheets and SPSS version 23. We gathered the qualitative data through face-to-face in-depth interviews., Results: The facilities spent 66,312,277.0 Ethiopian birrs to procure 518 pharmaceuticals between 2017 and 2019. Of the total products, 68 (13.1%) belonged to class A and 353 (68.1%) belonged to class C. Among 427 items identified by VEN analysis, 202 (47.3%) were vitals, and 201 (47.1%) were essential products making the highest proportions. Cross-tabulations of ABC and VEN showed that 230 (53.9%) items formed category I, representing 84.3% of total expenditures. Sterile surgical gloves #7.5, amoxicillin capsules, examination gloves, and 40% dextrose injection were among the top-ten high-value closing inventories, accounting for 21% of class X items. The fast-moving items were the most prevalent in all years, accounting for more than 45%, and shared the maximum expenditure, up to 90%. Scarcity of infrastructure and skilled human resources, shortage of pharmaceuticals and problems with suppliers, and management issues were the major challenges in the health facilities., Conclusion: Most of the items identified by ABC-VEN and FSN-XYZ were Category one, i.e., mainly vital costly products and a few fast-moving items with high closing inventory values, respectively, suggesting close supervision. However, several issues became impediments. Hence, facilities should alleviate the bottlenecks and monitor the stock status to prevent theft and stock out., (© 2022. The Author(s).)

- Abstract
Background: Despite the growing evidence that malaria and anaemia are two interlinked health problems of school-aged children (SAC) in developing countries, there is scarce information about malaria among SAC in Ethiopia. Moreover, anaemia-related studies were more concentrated in easily accessible areas. This study aimed to assess the prevalence of malaria and anaemia and corresponding risk factors among SAC in Dara Mallo and Uba Debretshay districts, in hard to reach areas, so as to inform appropriate integrated interventions for both diseases., Methods: This study was part of baseline data collected for a cluster-randomized trial registered in Pan African Clinical Trials Registry (PACTR202001837195738). Data were collected from 2167 SAC and their households through face-to-face interview; malaria was diagnosed by using rapid diagnostic test (RDT); haemoglobin concentration was determined using hemoCue hb 301 and adjusted for altitude to determine anaemic status; helminth infections were determined by using kato-katz, and anthropometric measurements were made to determine nutritional status of children. Generalized mixed effects logistic regression model was used to assess the association between predictor variables and malaria and anaemia using school as a random variable., Results: The overall prevalence of malaria was 1.62% (95% CI 1.15-2.27%) (35/2167). Of the 35 children positive for malaria, 20 (57.14%), 3 (8.57%) and 12 (34.29%) were due to Plasmodium falciparum, Plasmodium vivax and mixed infections of P. falciparum and P. vivax, respectively. Malaria was significantly lower among children from literate household head (Adjusted OR = 0.38; 95% CI 0.15-0.95) and residence house located at an altitude range above 1100 masl (AOR = 0.40; 95% CI 0.17-0.94). The prevalence of anaemia was 22.00% (95% CI 20.3-23.8%) (477/2167) and was significantly reduced by eating legumes, nuts or seed group of food in their 24-h dietary diversity recall (AOR = 0.64; 95% CI 0.41-0.99)., Conclusions: The prevalence of malaria was low and unevenly distributed per school while the overall prevalence of anaemia was moderate. It is important to implement integrated interventions targeting both malaria and anaemia, with special emphasis given to children from illiterate households and living at an altitude below 1100 masl. The micronutrient content of locally grown legumes should be further investigated to recommend specific interventions to overcome anaemia., (© 2021. The Author(s).)

- Abstract
Background: Malaria is one of the major causes of morbidity and mortality among school-age children (SAC) in sub-Saharan Africa. SAC account for more than 60% of the reservoir of malaria transmission, but they are given less emphasis in prioritizing malaria prevention interventions. This study was aimed at assessing the ownership of long-lasting insecticide treated bed nets (LLINs), its utilization and factors associated with ownership of LLINs by households and LLINs utilization among SAC in malaria-prone areas of Dara Mallo and Uba Debretsehay districts in Southern Ethiopia, October to December 2019., Methods: This study is part of a baseline assessment in a cluster-randomized controlled trial. The data was collected through interview and observation, following a structured questionnaire, of 2261 SAC households. Univariable and multivariable multilevel logistic regressions were used to assess the association between LLINs ownership and utilization and potential predictor variables. Odds ratio (OR) and corresponding 95% confidence interval (CI) were used to determine the strength and statistical significance of association., Results: The ownership of at least one LLIN by households of SAC was about 19.3% (95% CI 17.7-21.0%) but only 10.3% % (95% CI 7.7-13.7%) of these households had adequate access of bed nets to the household members. Ownership of bed net was marginally affected by living in semi-urban area (adjusted OR = 2.6; 95% CI 1.0-6.9) and occupational status of the household head being a civil servant (adjusted OR = 2.7; 95% CI 0.9-7.9). About 7.8% (95% CI 6.7-10.0%) of all SAC participated in the study and 40.4% (95% CI 57.4-66.7%) of children in households owning at least one LLIN passed the previous night under LLIN. LLIN utilization by SAC conditional to presence of at least one net in the household was significantly correlated with education level of mother above grade 6 (adjusted OR = 3.4; 95% CI 1.3-9.3) and the household size to bed net ratio less than or equal to 2 (adjusted OR = 20.7; 95% CI 4.7-132.5)., Conclusion: Ownership of bed net was lower than universal coverage of at least one bed net for two individuals. It is important to monitor replacement needs and educate mothers with low education level with their SAC on the benefit of consistent utilization of bed nets.

- Abstract
Background: Preterm birth (PTB) can be caused by different factors. The factors can be classified into different categories: socio demographic, obstetric, reproductive health, medical, behavioral and nutritional related. The objective of this review was identifying determinants of PTB among mothers who gave birth in East African countries., Methods: We have searched the following electronic bibliographic databases: PubMed, Google scholar, Cochrane library, AJOL (African journal online). Cross sectional, case control and cohort study published in English were included. There was no restriction on publication period. Studies with no abstracts and or full texts, editorials, and qualitative in design were excluded. Funnel plot was used to check publication bias. I-squared statistic was used to check heterogeneity. Pooled analysis was done by using fixed and random effect model. The Joanna Briggs Critical Appraisal Tools for review and meta-analysis was used to check the study quality., Results: A total of 58 studies with 134,801 participants were used to identify determinants of PTB. On pooled analysis, PTB was associated with age < 20 years (AOR 1.76, 95% CI: 1.33-2.32), birth interval less than 24 months (AOR 2.03, 95% CI 1.57-2.62), multiple pregnancy (AOR 3.44,95% CI: 3.02-3.91), < 4 antenatal care (ANC) visits (AOR 5.52, 95% CI: 4.32-7.05), and absence of ANC (AOR 5.77, 95% CI: 4.27-7.79). Other determinants of PTB included: Antepartum hemorrhage (APH) (AOR 4.90, 95% CI: 3.48-6.89), pregnancy induced hypertension (PIH) (AOR 3.10, 95% CI: 2.34-4.09), premature rupture of membrane (PROM) (AOR 5.90, 95% CI: 4.39-7.93), history of PTB (AOR 3.45, 95% CI: 2.72-4.38), and history of still birth/abortion (AOR 3.93, 95% CI: 2.70-5.70). Furthermore, Anemia (AOR 4.58, 95% CI: 2.63-7.96), HIV infection (AOR 2.59, 95% CI: 1.84-3.66), urinary tract infection (UTI) (AOR 5.27, 95% CI: 2.98-9.31), presence of vaginal discharge (AOR 5.33, 95% CI: 3.19-8.92), and malaria (AOR 3.08, 95% CI: 2.32-4.10) were significantly associated with PTB., Conclusions: There are many determinants of PTB in East Africa. This review could provide policy makers, clinicians, and program officers to design intervention on preventing occurrence of PTB.

- Abstract
Objective: There is a scarcity of reference interval studies on the elderly in Africa. This study establishes reference interval for the elderly for some commonly used biochemical parameters. In this study, 255 conveniently sampled, healthy elderly, participants meeting Clinical and Laboratory Standards Institute (CLSI C28-A3) guidelines were enrolled. The results obtained may have utility in clinical diagnosis, patient management and research., Results: In general, the consensus reference interval established in this study tended to be higher than reference interval from Caucasian populations; but lower than those obtained from reference interval studies in several African countries. This pattern was observed in a number of analytes including Alanine aminotransferase; aspartate aminotransferase; alkaline phosphatase; sodium; potassium among others. Significant sex-related variations were also observed in total bilirubin; direct bilirubin; indirect bilirubin; albumin; sodium; chloride; plasma carbon dioxide, creatinine and anion gap. The results demonstrate that reference interval for Eritrean urban population differs from those derived from other African or North American populations. In this regard, the use of reference interval values obtained from Caucasian populations may result in misdiagnosis.

- Abstract
Background: One way that people get infected with intestinal parasites is through the consumption of contaminated vegetables and fruits. This study aimed at determining the prevalence and predictors of parasitic contamination of fruits and vegetables collected from four local markets in Arba Minch town, Southern Ethiopia., Methods: A cross-sectional study was conducted from 1 to 21 September 2014 to determine the level of parasitic contamination of fruits and vegetables sold in Arba Minch town. A total of 360 samples of different types of fruits and vegetables were soaked in physiological saline, followed by vigorous shaking with the aid of a mechanical shaker for 15 minutes and then examined using the sedimentation concentration technique., Results: Out of the 360 samples examined, 196 (54.4%) were contaminated with at least one type of parasite. Ascaris lumbricoides (20.83%) was the most frequently detected parasite and Isospora belli (3.06%) was the least frequently detected one. It was also observed that decreased parasitic contamination was significantly associated with washing the products before displaying it for selling (P < 0.001)., Conclusions: The findings of this study provide evidence that there is a potentially high risk of acquiring parasitic infections from the consumption of raw vegetables and fruits in Arba Minch, Ethiopia. The authors believe that an effort should be made by the relevant bodies to reduce the rate of contamination of products with medically important parasites by educating the vendors and the community.

- Abstract
Background: Severe acute malnutrition remains one of the most common causes of morbidity and mortality in Sub-Saharan Africa. The objective of this study was to investigate morbidity and mortality trends and factors associated with mortality of under-five children admitted and managed for severe acute malnutrition in NEMMH., Methods: Four years retrospective cohort study was conducted on 500 under-five children admitted with the diagnosis of severe acute malnutrition. The study population was all under- five children admitted to the inpatient nutrition unit between 2012 and 2015. Data was entered using Epi-Data version 3.1 and exported to SPSS version 16 for analysis. A Kaplan- Meier curve was also used to estimate survival probability of different types of severe acute malnutrition. Cox proportional hazards regression was used to predict the risk of death among predictor while adjusting for other variables. A P-value less than 0.05 was considered as statistically significant., Result: A total of 500 children were enrolled into the study. Kwashiorkor was the most frequently recorded morbidity accounting for 43.0%. Pneumonia was seen the commonest form of comorbid disease. It was the most common co-morbidity across all morbidity groups. (27.6% in kwashiorkor, 37.5% in marasmus and 37.7% in marasmic-kwashiorkor). The average length of stay in the hospital was 11 days.Children with new admission were 86% less likely to die than repeated admission given that the children were admitted to paediatric ward (HR: 0.14, 95% CI: (0.06, 0.35). Kaplan Meier survival curves also showed children with marasmus and those with repeated admission had reduced survival rates. The overall mortality rate was 7%. The mortality trends vary irregularly in each year but morbidity trend increased with admission from 2014 to 2015., Conclusion: Mortality trends of SAM vary irregularly across the years but morbidity trends increased with admission from 2014 to 2015. An admission type was significantly associated with mortality. Morbidity and co-morbid diseases did not show significant effect on mortality of the children. Health extension workers and stakeholders should give due concern on promotion of proper nutrition in a community., Competing Interests: The authors declare that they have no competing interest., (© The Author(s). 2017.)

- Abstract
Background: Recent studies have presented conflicting findings about whether malaria is associated with an increased or decreased risk of malnutrition. Therefore, assessing the relationship between these two disastrous diseases in the most vulnerable groups, such as in children aged below 5 years (under-five children), may lead to the discovery of new low-cost and effective aides to current methods of malnutrition prevention in malaria-endemic areas. Therefore, this study was conducted to assess the relationship between malaria and malnutrition among under five children in an area with a high degree of malaria transmission., Methods: The study involved comparing malnourished children aged 6-59 months and nourished children of the same age for their past exposure to malaria, in Shashogo District, Southern Ethiopia. A validated structured questionnaire was used to collect home to home socioeconomic data and anthropometric instruments for clinical data. The collected data were analysed using descriptive and inferential statistics by means of EpiData entry software and STATA data analysis software., Results: A total of 356 (89 malnourished and 267 nourished) under-five children participated in the study. Previous exposure to Plasmodium infection was found to be a predictor for the manifestation of malnutrition in under-five children (P = 0.02 [OR = 1.87, CI = 1.115-3.138]). Children from a household with a monthly income of less than USD 15 were 4.5 more likely to be malnourished as compared to the other children (P = 0.001 [OR = 0.422, CI = 0.181-0.978])., Conclusion: This study found that exposure to Plasmodium has a significant impact on the nutritional status of children. In addition, socio-demographic factors, such as family income, may play a role in determining whether children are malnourished or not and may lead to increased morbidity due to malnourishment in children living in malaria-endemic areas. Therefore, malnutrition control interventions should be consolidated with malaria prevention strategies particularly in high malaria transmission areas.

- Abstract
Background: The use of herbal medicine has been on increase in many developing and industrialized countries. More pregnant women use herbal remedies to treat pregnancy related problems due to cost-effectiveness of therapy and easy access of these products. We sought to assess the prevalence of herbal medicine use and associated factors among pregnant women attending antenatal clinics of public health facilities., Methods: Facility based cross sectional study was conducted among 363 pregnant women attending antenatal clinics from May to June 2015 at public health facilities in Hossana town, Hadiya zone, Southern Ethiopia. Pretested structured questionnaire was used to collect data from each study subject. Bivariate logistic regression analysis was used to see significance of association between the outcome and independent variables. Odds ratios at 95 % CI were computed to measure the strength of the association between the outcome and the independent variables. P-value <0.05 was considered as a statistically significant in multivariate analysis., Result: Two hundred fifty eight (73.1 %) of pregnant women used herbal medicine during current pregnancy . The herbal medicines commonly taken during current pregnancy were ginger (55.8 %), garlic (69.8 %), eucalyptus (11.6 %), tenaadam (rutachalenssis) (26.4 %), damakesse (ocimumlamiifolium) (22.8 %), feto (3.5 %) and omore (3.1 %). Being students (AOR: (5.68, 95 % CI: (1.53, 21.13), second trimester of pregnancy (AOR: 0.22, 95 % CI: (0.08, 0.76), sufficient knowledge on herbal medicine (AOR: 0.37, 95 % CI: (0.19, 0.79), no formal education (AOR: 4.41, 95 % CI: (1.11, 17.56), primary education (AOR: 4.15, 95 % CI: (1.51, 11.45) and secondary education (AOR: 2.55, 95 % CI: (1.08,6.03) were significantly associated with herbal medicine use., Conclusion: The findings of this study showed that herbal medicine use during pregnancy is a common experience. Commonly used herbal medicines during current pregnancy were garlic, ginger, tenaadam, damakasse and eucalyptus. Educational status, occupation, knowledge on herbal medicine and second trimester of pregnancy were the major factors affecting use of herbal medicine. Health education about the effects of herbal medicine on pregnancy should be given during antenatal care sessions and through media. Health care providers, especially those that are involved in antenatal care should aware of evidence regarding potential benefits or harm of herbal medicinal agents when used by pregnant women.

- Abstract
Background: Plantar ulcers, which commonly occur in leprosy patients, tend to recur increasing physical disability. The aim of this study is to identify both the bacteriological profile of these ulcers and the antibiotic susceptibility of the isolated bacteria., Materials and Methods: 68 leprosy patients with chronic ulcers attending the in-patient department of Gambo General Hospital, West Arsi, were included in this study. Proper sample collection, inoculation on culture media, and final identification using biochemical methods were undertaken., Results: 66 patients (97.1%) had a positive culture. A total of 81 microorganisms were isolated. Multiple organisms (two or more) were isolated in 15 (22.7% out of positive culture) patients. The main isolation was Proteus spp (30.9%), followed by Escherichia coli (21.0%), Staphylococcus aureus (18.5%) and Pseudomonas aeruginosa (9.9%). In the total number of the isolated bacteria, the antibiotics with less resistance were gentamicin (18.5%), fosfomycin (22.2%) cefoxitin (24.7%), ceftriaxone (25.9%) ciprofloxacin (25.9%), and amoxicillin-clavulanic acid (28.49%)., Conclusion: The bacteriological study of plantar ulcers of leprosy patients revealed Enterobacteriaceae and S. aureus as the main pathogens involved in such infections. The results of this study may guide empirical therapy in a rural area hospital where culture and susceptibility testing facilities are scarce.
