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.

First report of cutaneous leishmaniasis caused by Leishmania donovani in Ethiopia.

BACKGROUND: Leishmaniasis is a common neglected tropical disease in Ethiopia. Visceral leishmaniasis (VL) caused by Leishmania donovani presents in the lowlands, while cutaneous leishmaniasis (CL) affects people living in the highlands. Although CL is described as being caused by Leishmania aethiopica, there is also evidence of L. tropica and L. major isolated from a patient, sand flies and potential reservoirs. Information on species causing CL in Ethiopia is patchy, and no nation-wide study has ever been done. Understanding which species are causing CL in Ethiopia can have important implications for patient management and disease prevention. METHODS: We analyzed stored routine samples and biobanked DNA isolates from previously conducted studies of CL patients from different centers in the north, center and south of Ethiopia. Species typing was performed using ITS-1 PCR with high-resolution melt (HRM) analysis, followed by HSP70 amplicon sequencing on a selection of the samples. Additionally, sociodemographic, clinical and laboratory data of patients were analyzed. RESULTS: Of the 226 CL samples collected, the Leishmania species could be determined for 105 (45.5%). Leishmania aethiopica was identified in 101 (96.2%) samples from across the country. In four samples originating from Amhara region, northwestern Ethiopia, L. donovani was identified by ITS-1 HRM PCR, of which two were confirmed with HSP70 sequences. While none of these four patients had symptoms of VL, two originated from known VL endemic areas. CONCLUSIONS: The majority of CL was caused by L. aethiopica, but CL due to L. tropica and L. major cannot be ruled out. Our study is the first to our knowledge to demonstrate CL patients caused by L. donovani in Ethiopia. This should spark future research to investigate where, how and to which extent such transmission takes place, how it differs genetically from L. donovani causing VL and whether such patients can be diagnosed and treated successfully with the currently available tools and drugs.

Household drinking water quality and its predictors in flood-prone settings of Northwest Ethiopia: A cross-sectional community-based study.

Globally, the deterioration of drinking water quality is a major public health problem that contributes to the spread of disease and causes death. Therefore, it is important to have regular quality control monitoring. This study aimed to assess the level of physicochemical and bacteriological quality of household drinking water and its contributing factors in flood-prone settlements of South Gondar Zone, Ethiopia. A community-based cross-sectional study was conducted in flood-prone settings of Northwest Ethiopia from January 17 to March 30, 2021. Structured questionnaires were used to gather the sociodemographic, environmental, and behavioral data. A total of 675 drinking water samples were collected from water storage containers of selected households. Logistic regression models were used for both univariate and multivariable studies. The survey included a total of 675 households. The mean values of pH (5.9 ± 1.03), turbidity (6.7 ± 2.21 NTU), and free residual chlorine (0.02 ± 0.01 mg/l) did not meet the WHO recommended limits for drinking water. The prevalence of fecal contamination of drinking water in the study area was 62.2% with [95% CI (53-60%)]. Family size [AOR = 2.205, 95% CI (1.375-3.536), absence of latrine [AOR = 3.449, 95% CI (1.349-8.823)], and lack of a separate container to draw water from its storage [AOR = 0.454, 95% CI (0.249-0.827)] were significant predictors for fecal contamination of household drinking water. In conclusion, the water quality in terms of pH, turbidity, residual chlorine, and bacteriological parameters was poor and not suitable for consumption. High prevalence of fecal contamination of water was found, and it was significantly associated with family size, the absence of a latrine, and the lack of a separate cap to take water from the storage. Therefore, continuous chlorination and monitoring its concentration, educating the community on how to use stored water, educating the advantage of having a latrine, and promoting point-of-use treatments such as filtration and boiling are needed.

Evaluation of Hookworm Diagnosis Techniques from Patients in Debre Elias and Sanja Districts of the Amhara Region, Ethiopia.

BACKGROUND: Inappropriate diagnosis could intimidate the prevention and control of hookworm infection. Thus, this study was aimed at evaluating the performance of hookworm diagnosis methods. METHODS: An institution-based cross-sectional study was conducted from patients in Debre Elias and Sanja districts of the Amhara region, Ethiopia, from November 2019 to January 2020. The study subjects were selected conveniently. After the data was entered into Statistical Package for the Social Sciences (SPSS), sensitivity, specificity, predictive values, test accuracy, and agreement of the different hookworm diagnosis methods, namely, test tube flotation technique (TFT), McMaster (MM), formol-ether concentration (FEC), Kato-Katz (KK), and direct wet mount microscopy (DWMM), were calculated by using SPSS software. The composite reference standard (CRS) was used as the gold standard method. The kappa (κ) test was used to measure the level of agreement between diagnosis tests. RESULT: A total of 389 stool samples were collected from patients in the study. The overall prevalence of hookworm was 63.24%. The test tube flotation technique (TFT) was found to be the highest both in terms of sensitivity and diagnostic accuracy (100%). McMaster (MM) was the second most sensitive test (68.7%), followed by FEC (44.3%) and KK (38.2%). On the other hand, DWMM had the lowest sensitivity (37.4%), and its diagnostic accuracy was also the least (60%). Only TFT had a perfect agreement (agreement = 100%, kappa = 1) with the CRS. The sensitivity of DWMM, KK, and FEC showed a kind of linear function with the intensity of infection, but TFT and MM methods were not affected by the infection intensity. CONCLUSION: Hookworm is still a public health problem in the study area. TFT is by far more sensitive than MM, FEC, KK, and DWMM techniques.

In vivo and in vitro efficacy of a single dose of albendazole against hookworm infection in northwest Ethiopia: open-label trial.

BACKGROUND: Control of hookworm and other soil-transmitted helminth infections primarily relies on preventive chemotherapy using a single dose of albendazole/mebendazole drugs on high-risk groups. Herein, the efficacy of a single dose (400 mg) of albendazole (ALB) was investigated both in vivo and in vitro model in northwest Ethiopia. METHODS: An open-label, single-arm clinical trial was conducted to assess anti-hookworm effect of albendazole. Stool samples were collected and examined using McMaster and Harada-Mori filter paper culture. Eligible hookworm-infected patients were treated with a single dose of ALB. After 14-21 days post-treatment, stool samples were also taken again and re-examined using the abovementioned technique. Egg reduction rate (ERR) and larval motility were used as a therapeutic outcome measure. An independent t test was used to compare the mean difference in egg counts, and probit analysis was performed for calculating the lethal concentration dose of albendazole. P value < 0.05 at 95% CI was considered statistically significant. RESULTS: A total of 70 participants had completed the drug efficacy study. The efficacy of ALB against hookworm in terms of CR and ERR was 87% and 93%, respectively. Participants who had not eaten one or more hours prior to treatment had higher CR than those who had eaten within 1 h before treatment (97.4% vs 74.2%), while individuals with heavy infection intensity had a lower post-treatment ova clearing rate than those who were with light infection intensity (43% vs 94.6%). The in vitro larvicidal effect of ALB was 63-93% after applying 50-250 µg/ml concentration of ALB solution. The LC50 and LC99 were 152 µg/ml and 573 µg/ml, respectively. CONCLUSION: A single dose of albendazole was found to be effective for treating hookworm infections according to WHO anthelminthic evaluation standard in the study area. Preventive chemotherapy might therefore be extended to risk groups, with proper continuous monitoring of its efficacy to strengthen and keep the ongoing control and prevention measures one step ahead. TRIAL REGISTRATION: This trial is retrospectively registered with www.pactr.org , number PACTR202010511829332 on October 26, 2020.

A Five-Year Trend of Intestinal Parasite Prevalence among Students Attending Clinic at University of Gondar, Northwest Ethiopia.

BACKGROUND: Intestinal parasitic infections are the cause of the highest worldwide infectious disease and the major public health problems in developing countries. Among the cases, children and younger age are at high risk and the major victims. The aim of this study was to assess the five-year trend of intestinal parasite prevalence among University of Gondar students. METHOD: A retrospective cross-sectional study was conducted to assess the trend of intestinal parasite prevalence among students at the University of Gondar. The data was collected from students who have studied at the University of Gondar from 2014 to 2018 and who visited the student's clinic and had recorded results of stool sample diagnosis on the laboratory logbook. Stool specimens were examined using direct saline wet mount methods. The data was analyzed by using SPSS version 20 software, and P value < 0.05 was considered as statistically significant. Moreover, chi-square was used to assess the association of different variables. RESULT: During the study period, a total of 6244 stool samples were requested for intestinal parasite diagnosis and it was found that 2850 specimens were positive for intestinal parasites, representing an overall prevalence of 45.6% with a fluctuating trend. Ten different parasites were reported with Entamoeba histolytica/dispar (20.3%) and Giardia lamblia (8.2%), the most frequently detected intestinal parasites. The prevalence of intestinal parasitic infections was higher in males (35.4%) than females (10.2%) (P = 0.02). CONCLUSIONS: Intestinal parasitic infection was highly prevalent, and there were fluctuations in the prevalence of intestinal parasites from 2014 to 2018. Environmental sanitation improvement and health education schemes at the University of Gondar can be considered quite indispensable for the prevention and control of parasitic infections in the area.

Comparison of direct wet mount, Kato-Katz and formol ether sedimentation technique for the diagnosis of hookworm infection in Debre Elias Woreda, Northwest Ethiopia.

Hookworm infection is a neglected parasitic disease. Direct wet mount is the usual method for the diagnosis of hookworm in Ethiopia, but its sensitivity is unsatisfactory. A cross-sectional study was therefore conducted from January to February 2018 among 192 study participants in Debre Elias district. Stool samples were processed by three methods: the prevalence of hookworm was 77.6%, 68.2% and 49.0% by Kato-Katz, formol ether sedimentation technique and direct wet mount, respectively. Direct wet mount had relatively low sensitivity (61.4%) compared to formol ether sedimentation technique (85.6%) and Kato-Katz (97.4%). The latter two compared well with the gold standard method with kappa values of κ = 0.94, κ = 0.71 and κ = 0.39, respectively, and are therefore recommended over against the direct wet mount technique in detecting hookworm.

Prevalence, Intensity, and Associated Factors of Schistosoma mansoni among School Children in Northwest Ethiopia.

BACKGROUND: Schistosomiasis is one of the Neglected Tropical Diseases in Ethiopia, and its burden may show variations from time to time across different regions. Thus, this study was aimed at determining the prevalence, intensity, and associated risk factors of Schistosoma mansoni (S. mansoni) among schoolchildren in Northwest Ethiopia. METHODS: A school-based cross-sectional study was conducted. A multistage sampling technique was used to select the study participants. Stool specimens were collected and examined using two-slide Kato-Katz method. Data were analyzed using SPSS version 20 software. Multivariate logistic regression analysis was used to identify risk factors. p values less than 0.05 were taken as statistically significant. RESULT: A total of 786 schoolchildren were participated in this study. The prevalence of S. mansoni was 33.5%. The mean egg count of the parasite among the infected study participants was 523.665 eggs per gram (epg) of stool. Thirty-seven, 42, and 21 percent of the study participant's infection were due to light, moderate, and heavy infection intensities, respectively. Age of 8-11 years old (AOR = 1,687, 95%CI = 1.163, 2.892), 5th-8th grade level (AOR = 2.280, 95%CI = 1.348, 3.856), residing in Chuahit District (AOR = 95.559, 95%CI = 12.945, 705.419), and using untreated water for domestic supply (AOR = 1.724, 95%CI = 1.457, 2.148) were found to be risk factors for S. mansoni infection. CONCLUSION: High prevalence of S. mansoni and relatively higher proportion of moderate intensity of infection in this study imply that schistosomiasis is still one of the major public health problems in Northwest Ethiopia. It is also highlighted that study sites, provision of water supply, age, and grade level of the schoolchildren were identified as a risk factors for the disease.

Trends and seasonal patterns in intestinal parasites diagnosed in primary health facilities in Northwest Ethiopia.

INTRODUCTION: Intestinal parasites have an insidious impact on human health. In response to high parasite frequencies in Northwest Ethiopia, mass drug administration (MDA) is provided for school children using albendazole/mebendazole (since 2007) and praziquantel (since 2015). The study objective was to assess trends and seasonal patterns of intestinal parasite infections in a context of MDA. METHODOLOGY: This was a descriptive study collecting routine data from laboratory registers in two health centres in Denbia district, Amhara region. Stool test results (wet-mount direct microscopy) from patients attending these centres between 2013 and 2018 were included. Frequencies of different parasite species were evaluated within and across the years and stratified by age and gender. RESULTS: From a total of 8002 stool test results, the overall parasite frequency was 53.3%; this proportion remained constant. The most frequently diagnosed soil-transmitted helminths (STH) were Ascaris lumbricoides (16.9%) and hookworm (3.9%). STH frequency varied over the years, but was similar at the beginning (20.0%) and the end (22.0%) of the six-year period. STH infections were more frequent in winter (December-February; 20.4%) than in other seasons (16.0%). The most frequently diagnosed protozoa were Entamoeba histolytica/dispar (18.5%) and Giardia lamblia (12.2%). The frequency of Giardia steadily increased from 9.6% in 2013 to 15.3% in 2018. E. histolytica/dispar peaked in summer and G. lamblia in autumn. CONCLUSIONS: Trends in routine laboratories may be a proxy for a status quo in the community. These findings suggest that higher MDA coverages and/or interventions beyond MDA are needed to reduce intestinal parasite-related morbidity.

Does mass drug administration affect Schistosoma mansoni infection trends in West Dembia district, Northwest Ethiopia?

INTRODUCTION: Schistosomiasis is one of the Neglected Tropical Diseases in Ethiopia. Since 2015, yearly school-based mass drug administration (MDA) using praziquantel has become the major control strategy. This study aimed to assess trends of Schistosoma mansoni infection in a high-endemic area in Northwest Ethiopia. METHODOLOGY: Data were extracted from routine laboratory logbooks at two health centers in West Dembia district, Amhara region, for the period 2013-2018. Wet-mount direct microscopy was used to diagnose intestinal parasites. Chi-square test was used to compare proportions of S. mansoni-positive results before and after the start of MDA with praziquantel, across sex, age groups, and seasons. RESULTS: Data of 8002 stool tests was extracted. The proportion of S. mansoni progressively decreased from 9.6% in 2013 to 4.1% in 2018 in the overall patient population and from 20.3% in 2013 to 8.8% in 2018 in school-aged children. However, a declining trend of S. mansoni was observed before the launch of MDA and remained constant after the start of the MDA. The positivity rate was significantly higher in males and in the 5-14 years age group. S .mansoni infection in school aged children showed significant seasonal variation. CONCLUSIONS: The declined trend of S. mansoni positivity rate is encouraging and may be related to the existence of intervention packages. Although the timing of MDA was related with low positivity rate of S. mansoni infection, it has not resulted in the expected beneficial effect. Therefore, the district health office should work on both MDA and other interventions.

Common Gastrointestinal Symptoms and Associated Factors Among Under-5 Children in Rural Dembiya, Northwest Ethiopia: A Community-Based Cross-Sectional Study.

BACKGROUND: Gastrointestinal (GI) symptoms such as abdominal discomfort, abdominal cramp, nausea, vomiting, gas in the GI tract, changes in bowel habits (e.g. diarrhea), or heartburn are common in the community. However, these symptoms may be misinterpreted and their impact and significance misunderstood, especially in the rural communities. This study was, therefore, conducted to assess common GI symptoms among children in rural Dembiya, northwest Ethiopia. METHODS: A community-based cross-sectional study was conducted in May 2017 among 225 randomly selected under-5 children. We primarily used mothers' report to assess GI symptoms. Health professionals also diagnosed for some symptoms. Direct stool examination technique was used to identify parasitic infections. Bacteriological analysis of drinking water was done to determine the quality of drinking water. Food safety, environmental sanitation, and hygiene condition of children were assessed using observation checklists. Multivariable binary logistic regression analysis was employed to identify factors associated with GI symptoms on the basis of adjusted odds ratio (OR) with 95% confidence interval (CI) and P < .05. RESULTS: The current study depicted that 139 of 225(61.8%) of the children had GI symptoms. Abdominal discomfort (137 of 139 [98.7%]), abdominal cramp (125 of 139 [89.9%]), and diarrhea (118 of 139 [84.9%]) were the highest GI symptoms reported. GI symptoms were significantly associated with childhood intestinal parasitic infections (OR = 13.69, 95% CI = 3.31-56.59), unclipped and unclean finger nails (OR = 2.28, 95% CI = 1.02-5.10), inadequate living environment sanitation (OR = 2.37, 95% CI = 1.08-5.18), unclean living houses (OR = 9.06, 95% CI = 2.60-31.54), and owning livestock (OR = 4.68, 95% CI = 1.82, 12.03). CONCLUSION: The prevalence of GI symptoms among under-5 children in rural Dembiya, northwest Ethiopia, was found to be high. GI symptoms were significantly associated with childhood intestinal parasitic infections, hand hygiene condition of children, and sanitation condition of the living environment. Therefore, preventing intestinal parasitic infections, improving hand hygiene condition, and promoting environmental sanitation will have overriding contributions to prevent symptoms among children in rural Dembiya.

Anopheles gambiae s.l (Diptera: Culicidae) seasonal abundance, abdominal status and parity rates in Metema-Armachiho lowland, Northwest Ethiopia.

BACKGROUND: Malaria is a life threating vector borne disease caused by different Plasmodium parasites. Metema and Armachiho are two of the top five malaria endemic areas among the districts of Amhara region in Ethiopia. Transmission pattern is seasonal and migrant laborers who visit these areas for employment in mechanized agriculture are highly affected. The aim of this study was to investigate seasonal abundance, abdominal status and parity rate of An.gambiae s.l in Metema-Armachiho lowlands, Northwest Ethiopia. METHOD: A 1 year longitudinal entomological study was conducted in Metema-Armachiho lowlands from June 2016-May 2017. Mosquitoes were collected using CDC-light traps in indoor and outdoor sites for four consecutive days in each month. A total of eight standard battery operated CDC-light traps were used to collect mosquitoes. Female mosquitoes were classed as unfed, fed or gravid under a dissecting microscope. The ovaries of all unfed An.gambiae s.l mosquitoes were examined for evidence of parity. Data were entered and analyzed using SPSS-20 software. Chi-square test was applied to show significant difference between variables. P-value< 0.05 was taken as statistically significant. RESULTS: Of the total 1253 mosquitoes collected, 713 (552 female, 161 male) were culex and 540 (501 female, 39 male) were An.gambiae s.l. About 50.9% were collected in June-August 2016, 21.7% in September-November 2016, 12.0% in December 2016-February 2017 and 15.4% in March to May 2017. Of the total, 57.2 and 42.8% of the An.gambiae s.l were collected from indoor and outdoor sites respectively. Of the total females collected, 76.8% were unfed; of which 69.4% were parous. Significantly higher number of female An.gambiae s.l were collected in indoor and there was significant difference in abdominal status of An.gambiae s.l mosquitoes collected in different season (P < 0.05). CONCLUSIONS: Highest number of An.gambiae s.l was observed from June-August followed by September-November. The parity rate of An.gambiae s.l was high and there was significant difference in abdominal status of An.gambiae s.l collected in different season.

A 7-Year Trend of Malaria at Primary Health Facilities in Northwest Ethiopia.

BACKGROUND: Malaria is a severe parasitic disease that can progress to complications of the nervous system, respiratory distress, renal problems, metabolic acidosis, and hypoglycemia which can result in death in case of delay or absence of appropriate treatment. Even though health service facilities and vector control strategy in the community are implemented as control measures, variations in temperature and rainfall that can affect the life cycle of parasite are among the factors of malaria prevalence over the years. The aim of this trend analysis was to assess the prevalence and the impact of malaria over the seasons and years. METHODS: A cross-sectional study using retrospective information was conducted at two health centers Gorgora and Chuahit in Dembia district. The data was collected from lab logbooks routinely diagnosed and registered for seven years. A systematic sampling technique was used by taking patient results from lab logbooks during the first ten days of every month. Data were entered directly into the EpiData Entry software version 3.1 and analysed with the SPSS software version 20. Moreover, a chi-square test with a level of significance set at less than 5% was used. RESULTS: From a total of 11,879 clients that participated, 56.6% were males. The overall malaria prevalence in the last seven years was 21.8%, and the dominant parasite was P. falciparum which accounted for 15.6% of the participants which was threefold higher than P. vivax in the seven-year trend. Moreover, at Gorgora health center, the prevalence which was 15% at the beginning of the study (2012) rose to 33.9% and 30.5% in 2017 and 2018, respectively. In the analysis of the seven years, October and September in which the prevalence of malaria was 32.6% and 27.2%, respectively, constituted the peak months. High malaria prevalence was observed in autumn (September to November) season, and the least was observed in spring (March to May) with the prevalence of (17.8%) (p ≤ 0.001). Malaria attack showed significant variability among different age groups, and the age group 15-29 and males were the most affected (p ≤ 0.001). CONCLUSION: In this study, malaria transmission remained high, which affected males more than females. Thus, appropriate season-based bed net use, health education, immediate patient treatment, and stagnant water drainage methods are needed to alleviate the problem.

The Prevalence of HIV-Positive Infants Born to HIV-Positive Mothers Attended at the University of Gondar Specialized Hospital Anti-Retroviral Therapy Services, Northwest Ethiopia, 2018.

INTRODUCTION: The human immunodeficiency virus (HIV) attacks the human immune cells and affects their function. It is the highest burden that occurs in a developing country. Ethiopia is one of the top ten countries in the world, which has a high burden of HIV-infected children. Even if the country works hard on the PMCT program, still there is challenging on MTCT reduction. OBJECTIVE: The purpose of this study was to assess the prevalence of HIV-positive infants born to HIV-positive mothers attending anti-retroviral treatment (ART) services at the University of Gondar specialized hospital, Gondar, northwest Ethiopia, 2018. METHODS: A retrospective chart review study was conducted from February to April 2018, among HIV-exposed infants who born to HIV-positive mothers in ART service at the University of Gondar specialized hospital. A systematic sampling method was applied to select study participants. Data were entered into EPI info version 7 statistical software and transferred to SPSS version 20 for analysis. RESULTS: In this study, 239 participants were enrolled, with a 98.8% response rate. The prevalence of HIV-positive infants born to HIV-positive mothers was 5.5% with a 95% CI (3.0-8.5%). Of the mothers, 77.1% were within 25-35 years of age range. Of the total infants, 56.8% were males. From these HIV-positive infants, 13 (5.5%) were born from age ranges of 25-35years old mothers, 9(3.8%) were females, 8(3.4%) were 6-11 months old, 13 (5.5%) were post-term gestation, and 13 (5.5%) were maternal CD4+ less than 350/mm3. CONCLUSION AND RECOMMENDATIONS: The prevalence of HIV-positive infants born to HIV-positive mothers in this study was lower than the previous 10.2%. To reduce such infant HIV infection to zero, it needs proactive action from stakeholders, health professionals, and the community at large.

Evidence of Households' Water, Sanitation, and Hygiene (WASH) Performance Improvement Following a WASH Education Program in Rural Dembiya, Northwest Ethiopia.

BACKGROUND: Water, Sanitation, and Hygiene (WASH) promotion is a viable solution to prevent enteric infections. It focuses on hygiene education, where a number of theoretical models have emerged which attempt to guide behavior change interventions. This study was, therefore, conducted to evaluate the effectiveness WASH education program on households' WASH performance in rural Dembiya, northwest Ethiopia. METHOD: An uncontrolled before-and-after intervention study was conducted. Baseline and endline surveys were done among 225 and 302 randomly selected households with under-5 children, respectively, using a structured questionnaire and observational checklists. Percent point change was used to see the effect of the intervention. Pearson χ2 and Fisher exact tests were used to test for statistically significant percentage point changes on the basis of P < .05. RESULT: Access to adequate sanitation was significantly improved from 43.1% at the baseline to 50.7% at the endline (P < .05). Access to protected water sources was high at the baseline (73.8%) and remained high (81.1%) at the endline (P < .05). Significant proportion of households (58.3%) practiced good drinking water handling at the endline compared with the baseline (6.7%) (P < .001). Practice of home-based water treatment was improved at the endline (47%) compared with the baseline (7.6%) (P < .001). The general hygienic condition of children was significantly improved at the end of the intervention compared with the conditions before the intervention (P < .05). At the end of the intervention, mothers' hand washing practice was improved to 68.2% from 24.4% at the baseline (P < .001). Moreover, 52.4% and 69.5% of the households at the baseline and endline, respectively, had good food safety practice (P < .05). CONCLUSION: The proportion of households who practiced water safety, basic sanitation, good personal hygiene, and basic food safety measures significantly increased at the endline. This significant increment clearly showed that our WASH interventions were effective to improve households' WASH performance in rural Dembiya. The local health office need, therefore, strengthens the WASH education program.

Sero-prevalence of Toxoplasma gondii and associated risk factors among psychiatric outpatients attending University of Gondar Hospital, Northwest Ethiopia.

BACKGROUND: Toxoplasmosis is caused by an obligatory intracellular coccidian protozoan organism, Toxoplasma gondii. It has a worldwide distribution, affecting one-third of the world population. Psychiatric patients have a higher risk of exposure to Toxoplasma gondii infection due to lack of good personal hygiene. The burden of toxoplasmosis among psychiatric patients in Ethiopia has not been studied extensively. Thus, the study aimed to determine the seroprevalence of Toxoplasma gondii and associated risk factors among psychiatric outpatients at the University of Gondar Comprehensive and Specialized Hospital Psychiatric clinic. METHODS: A cross-sectional study was conducted at the University of Gondar Comprehensive and Specialized Hospital from February to May 2018. Venous blood was collected from 304 study participants (152 psychiatric outpatients and 152 control groups). Anti-toxoplasma antibodies were determined using Onsite Toxo immunoglobulin G (IgG) and immunoglobulin M (IgM) Rapid Test. A Chi-square test was carried out to compare the two groups and a logistic regression analysis was conducted to check the association between variables. P-value less than 0.05 was taken as statistically significant. RESULTS: The seroprevalence rate of anti-Toxoplasma gondii IgG antibodies was 33.6, and 16.4% in the psychiatric outpatients and the control samples, respectively. Anti-Toxoplasma gondii IgM sero-prevalence was 1.3% in the former patients and 3.9% in the latter group. Owing cat (AOR = 2.862 95% CI = 1.445-5.666 P = 0.003), cleaning cat excreta (AOR = 2.966 95% CI = 1.317-2.652 P = 0.007), and farming (AOR = 2.058 95% CI = 1.018-4.163 P = 0.045) were found to be significantly associated with the sero-prevalence of anti-Toxoplasma gondii IgG antibody. CONCLUSIONS: This study highlighted that, the prevalence of anti-Toxoplasma gondii IgG antibodies was significantly higher in psychiatric outpatients than the control group (p = 0.001). Cat ownership, cleaning of cat excreta, and farming were found to be statistically significantly associated with the seroprevalence of anti-Toxoplasma gondii IgG antibody.

The Prevalence of Malaria among Pregnant Women in Ethiopia: A Systematic Review and Meta-Analysis.

BACKGROUND: Malaria during pregnancy remains a major public health concern in tropical and subtropical countries. Moreover, malaria is increasingly associated with unwanted pregnancy outcomes such as an increased risk of abortion, stillbirth, premature delivery, and low-birthweight infants. Since pregnant women are most vulnerable to malaria, implementation of the appropriate prevention and control measures among this group is very important. Therefore, the current review was designed to assess the prevalence of both symptomatic and asymptomatic malaria among pregnant women in Ethiopia. METHOD: In this systematic review and meta-analysis we have followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline. The databases used were PubMed, Google Scholar, HINARI, and Science Direct literature. Search terms used were "prevalence", "malaria", "pregnant women", and "Ethiopia". Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument (JBI-MAStARI) was used for critical appraisal of studies. The meta-analysis was conducted using STATA 14 software. The pooled meta-logistic regression was computed to present the pooled prevalence with a 95% confidence interval (CI). RESULT: Among a total of 10207 studies, seven studies were included in this analysis. The estimated pooled prevalence of malaria among pregnant women in Ethiopia was 12.72% (95% CI: 7.45, 17.98). In subgroup analysis, the prevalence of malaria showed a significant variation between asymptomatic and symptomatic cases, which was 7.83% (95% CI: 2.23, 13.43) and 17.97% (95% CI: 7.31, 28.92), respectively. CONCLUSION: The current systematic review and meta-analysis showed that the pooled prevalence of malaria among pregnant women was found to be relatively higher compared with the general population. Therefore, the existing prevention and control measures should be strengthen.

Effects of water, sanitation and hygiene (WASH) education on childhood intestinal parasitic infections in rural Dembiya, northwest Ethiopia: an uncontrolled before-and-after intervention study.

BACKGROUND: Soil-transmitted helminthes (STH) infections are among the most common infections worldwide and affect the most deprived communities. Adequate water, sanitation, and hygiene (WASH) prevents environmental contamination, thereby preventing transmission of STH. Cognizant of this, WASH education was implemented in rural Dembiya to reduce intestinal parasitic infections. This study was, therefore, conducted to assess the impacts of the intervention on households' WASH conditions and prevalence of intestinal parasitic infections. METHOD: An uncontrolled before-and-after intervention study was used. Cross-sectional studies were done before and after the intervention. Two hundred twenty-five and 302 under five children were recruited randomly at the baseline and endline, respectively. Data were collected using a structured questionnaire and observational checklists. Direct stool examination and Kato-Katz methods were used to identify parasites in the stool. We used percent point change and prevalence ratio (PR) to see the effects of the intervention on WASH conditions and prevalence of intestinal parasitic infections respectively. Pearson chi-squared and Fisher's exact tests were used to test for statistically significant percentage point changes of WASH conditions. The effect of the intervention on intestinal parasitic infections was statistically tested on the basis of PR with 95% confidence interval (CI). RESULTS: The baseline prevalence of intestinal parasitic infections was 25.8%, and the endline prevalence was 23.8%. The prevalence of intestinal parasitic infections was not significantly decreased at the endline compared with the baseline [PR = 0.92, 95% CI = (0.62, 1.38)]. Ascaris Lumbricoides was the most prevalent parasitic infection both at the baseline and endline. The proportion of children who had good hygienic condition increased from 1.3% at the baseline to 34.4% at the end line (p <  0.05). The percentage of mothers/care givers who washed hands at different pick times was significantly increased from 24.4% at the baseline to 68.2% at the endline (p <  0.001). The proportion of households who practiced home-based water treatment was significantly increased from 7.6% at the baseline to 47% at the endline (p <  0.001). The proportion of households who used sanitary latrine was increased from 32% at the baseline to 49% at the endline (p <  0.05). CONCLUSION: This before-and-after intervention study found that households' WASH performance was significantly improved at the endline compared with the baseline. The endline prevalence of intestinal parasitic infections was slightly lower than the baseline prevalence; however, the reduction was not statistically significant. The local health office needs to strengthen the WASH education program, mobilize the community to construct WASH facilities, and support the community to sustain households' WASH performance.

Prevalence of Anemia and Associated Factors Among Hospitalized Children Attending the University of Gondar Hospital, Northwest Ethiopia.

BACKGROUND: Anemia in children continues to be a major public health challenge in most developing countries, particularly in Africa.In the early stages of life, it leads to severe negative consequences on the cognitive functions as well as growth and development of the children, which may persist even after treatment. OBJECTIVE: The main aim of this study was to assess the prevalence and associated factors of anemia among hospitalized children attending at university of Gondar comprehensive and specialized referral hospital, Northwest Ethiopia. METHOD: A cross sectional study was conducted on 384 hospitalized children, between February and June, 2018. Data of socio demographic characteristics and clinical conditions of the study individuals were collected using questionnaire after taking appropriate written informed consent and assent. Then 3 mL of blood was collected for complete blood count analysis and also stool examination was done for intestinal parasites. Data were coded, cleared and entered into SPSS version 20 for analysis.Bivariate and multivariate logistic regression models were used to identify associated factors of anemia. P-value ≤ 0.05 was considered as statistically significant. RESULT: The overall magnitude of anemia among hospitalized children was 58.6%; of them 56.4% were males. Of anemic children, 28% had mild, 51.1% moderate and 20.9% severe anemia. The magnitude of anemia among children aged 6-59 months, 5-11 years and 12-14 years were 54.1%, 58.9% and 67.5%, respectively.In this study, anemia was positively associated with parasitic infection (AOR= 2.541; 95% CI: 1.363, 4.737), not eating meat and animal products (AOR = 1.615; 95% CI: 1.014, 2.574). CONCLUSION: Anemia among hospitalized children in this study was found to be a severe public health problem. It was strongly associated with intestinal parasitic infection and not eating meat and animal products.Focused polices and strategies should be designed to reduce anemia among hospitalized children in Ethiopia.
