Association between Khat Chewing and Gastrointestinal Disorders: A Cross Sectional Study

Background: Khat (Catha edulis Forsk) is a psycho-stimulant substance grown in East Africa. But its adverse effects and its prevalence are not well studied. The main aim of the present study is thus to assess the association between khat chewing and GI problems among students in Ambo University.Methods: A cross-sectional study was conducted in January 2010 on 1005 Ambo University students. Study subjects were selected using systematic random sampling technique, and data were collected using self-administered questionnaire. Data analysis was made using SPSS version 16.0 for windows package.Results: The mean age of the respondents was 20.79 ± 1.39 ranging from 18-30 years. Seven hundred twenty (71.6 %) of the study participants were males and 994 (98.9%) were in the age group of 15- 24 years. The prevalence of gastritis was 580 (57.7%); constipation 235 (23.4%); hemorrhoids 54 (5.4%) and that of dental problems (carries, decay, filling and extraction) was 225 (22.4%) of all study participants. Gastrointestinal disorders were found to be higher among khat chewers, where 64(36.2%) of them had dental problems; 127(71.8%) symptoms of gastritis; 86(48.6%) constipation and 26(14.7%) hemorrhoids which demonstrated statistically significant association with p < 0.001.Conclusions: The prevalence of gastrointestinal disorders was found to be higher among khat chewers, indicating that khat chewing could be a predisposing factor to gastrointestinal disorders. Community-based awareness creation about the adverse effect of khat use is thus recommended.Keywords: Khat chewing, Gastritis, Constipation, Hemorrhoid

Magnitude of Anemia and Associated Risk Factors among Pregnant Women Attending Antenatal Care in Shalla Woreda, West Arsi Zone, Oromia Region, Ethiopia

Background: Anemia during pregnancy is a common problem in developing countries and affects both the mother’s and her child’s health. The main objective of this study was to determine the prevalence of and the factors associated with anemia among pregnant women.Methods: Facility based cross-sectional study design was conducted from June to August, 2011 on 374 pregnant women. Mothers who came for ANC during the study period and who met the inclusion criteria were interviewed and a capillary blood sample was taken. Hemoglobin level was determined by using HemoCue photometer, and interviewer administered questionnaire was used to collect data. Data were cleaned, coded and fed into SPSS version 16.0 for analysis.Result: The mean hemoglobin concentration was 12.05 + 1.5 g/dl and prevalence of anemia was 36.6%. Family sizes (COR=2.67, CI (1.65, 4.32), third trimester (COR=1.45, CI (1.11, 2.23), meat consumption <1x/wk (COR=3.47, CI (1.58, 7.64) and pica (COR=2.33, CI (1.52, 3.58) were significantly associated with anemia. Having five or more children (AOR=5.2, CI [1.29, 21.09]), intake of vegetables and fruits less than once per day (AOR= 6.7, CI [2.49, 17.89]), intake of tea always after meal (AOR = 12.83.CI [45-28.9]), and recurrence of illness during pregnancy (AOR=7.3, CI [2.12-25.39]) were factors associated with anemia.Conclusion: This study showed that anemia is a moderate public health problem. Less frequent meat and vegetable consumption, parity ≥5 are risk factors for anemia. Therefore, reducing parity, taking balanced diet and use of mosquito nets during pregnancy are recommended.Keywords: Hemoglobin, Anemia, Pregnancy, AN

Assessing the Bacteriological Quality of Drinking Water from Sources to Household Water Samples of the Rural Communities of Dire Dawa Administrative Council, Eastern Ethiopia

In Ethiopia, access to improved water supply and sanitation was estimated at 38% and 12% respectively. Three- forth of the health problems of children in Ethiopia are communicable diseases due to polluted water and improper water handling practices. Thus, this study was conducted to assess the bacteriological quality of drinking water sources in Dire Dawa Surrounding area. The study was conducted from February 2011 to May 2011. A total of 90 water samples from different water sources (-protected and unprotected well; protected and unprotected spring; and tap water) and bacteriological water quality parameters were analyzed using the membrane filtration method. Water analysis demonstrated that all water sources in the study areas were contaminated with total coliforms, fecal coliform and parasites. The average counts of TC were in the range of 1.5-133.05CFU/100ml whereas the average counts of FC were found to be 0.34- 54CFU/100ml. In all samples, the TC, FC was above the  recommended limit of WHOM for drinking water quality (1-10CFU/100ml for TC, 0CFU/100ml for FC. The fact that, about 83.34% of the water  sample was positive for indicator bacteria shown that the three selected PA had risk of contamination in the three selected PAs had high risk of microbiological water quality parameters. High concentration of  microbiological indicators in all water sources of this study area may  demonstrated the presence of pathogenic organisms which constitute a threat to anyone consuming or in contact with these waters. This is due to lack of good water treatment, improper water handling practices and lackof the protection of the water sources. Consequently, protection of water sources accompanied by sanitation and hygiene promotion programs can improve the water quality of rural water sources, where disinfection is not feasible

Determination of body composition of people living with HIV/AIDS: A comparison of air displacement plethysmography with Tanita segmental body composition analyzer

Background: Body composition (BC) assessment of patients living with HIV is frequently done by a variety of methods. During the past decades, several new technologic developments have introduced different methods of BC assessment. Yet, simple, accurate, and noninvasive methods for assessing BC are needed in clinical, community, and research settings. Objective: To compare BC assessed by air displacement plethysmography (ADP) with that assessed by Tanita segmental BC analyzer in patients with HIV/AIDS.Method: Eighty-eight adult (> 18 years) HIV/AIDS patients who were on follow up at anti-retroviral clinic in Jimma university medical centre were randomly selected. ADP and Tanita segmental BC analyzer were used to collect data. Agreement between the methods was tested using paired t-test, Pearson’s correlation, and linear regression. Result: Thirty-nine (57.4%) of the patients were female and 29 (42.6%) were male. About 41(60.3%) of them were malnourished. The patients who were in stage one of the disease accounted 83.8%. Mean value of %BF measured by Tanita segmental BC analyzer was significantly lower than %BF measured by the ADP (mean difference = 3.2, p < 0.001). Regardless of the difference in mean, %BF assessed by the two methods were strongly correlated (r = 0.98, p < 0.001). Conclusion: Estimates of %BF by Tanita segmental BC analyzer and ADP in people living with HIV/AIDS in Southwest Ethiopia showed significant difference. Tanita segmental BC analyzer significantly underestimated %BF in HIV/AIDS patients

Two-Dimensional \u3csup\u3e1\u3c/sup\u3eH NMR Studies on Octahedral Nickel(II) Complexes

The dinucleating ligand ethylene glycol−bis(β-aminoethyl ether) N,N,N‘,N‘-tetrakis[(2-(1-ethylbenzimidazoyl)] (EGTB-Et; 1) was used to synthesize the dinuclear Ni(II) tetraacetonitrile complex cation [Ni2(EGTB-Et)(CH3CN)4]2+ (2):  triclinic space group P1̄ (a = 12.273(5) Å, b = 12.358(7) Å, c = 12.561(6) Å, α = 90.43(4)°, β = 110.26(3)°, γ = 99.21 (4)°, and Z = 1). The structure shows two identical octahedral Ni(II) centers each bound to two benzimidazole ring nitrogen atoms, one amine nitrogen atom, an ether oxygen atom, and two acetonitrile nitrogen atoms. The Ni(II) ions are tethered together by a diethyl ether linkage with a crystallographic center of inversion between the methylene carbons of this bridge. The Ni--Ni separation in 2 is 7.072 Å. The mononuclear Ni(II) complex cation [Ni(Bipy)2(OAc)]+ (3) (Bipy = bipyridine) was synthesized and crystallographically characterized:  monoclinic space group P21/c (a = 9.269(4) Å, b = 8.348(4) Å, c = 14.623(7) Å, and β = 102.46(4)°, Z = 2). The Ni(II) ions in 3 adopts a distorted octahedral geometry and is bound to four bipyridine ring nitrogen atoms and two carboxylate oxygen atoms. The average Ni−N and Ni−O distances are 2.062 and 2.110 Å. The electronic absorption spectra of both 2 and 3 were recorded in acetonitrile solution and are consistent with octahedral coordination geometries about the Ni(II) ions with Racah parameters of 840 and 820 cm-1, respectively. Both one- and two-dimensional 1H NMR techniques were used to assign the observed hyperfine shifted 1H NMR resonances of 2 and 3 in acetonitrile solution. Clear COSY cross signals are observed between the aromatic protons of both the benzimidazole and pyridine protons of 2 and 3, respectively. The use of 2D NMR methods to assign inequivalent aromatic protons rather than synthetic methods such as substitution or deuteration are discussed

Longer delays in diagnosis and treatment ofpulmonary tuberculosis in pastoralist setting, Eastern Ethiopia

Purpose: This study aimed to assess the extent of patient, health system and total delays in diagnosis and treatment of pulmonary tuberculosis (TB) in Somali pastoralist setting, Ethiopia. Patients and Methods: A cross-sectional study among 444 confirmed new pulmonary TB patients aged ≥15 years in 5 TB care units was conducted between December 2017 and October 2018. Data were collected using a structured questionnaire and record review. We measured delays from symptom onset to provider visit, provider visit to diagnosis and diagnosis to treatment initiation. Delays were summarized using median days. Mann- Whitney and Kruskal-Wallis tests were used to compare delays between categories of explanatory variables. The Log-binomial regression model was used to reveal factors associated with health system delay ≥15 days, presented in adjusted prevalence ratio (APR) with 95% confidence interval (CI). Results: The median age of patients was 30 years, ranged from 15 to 82. The majority (62.4%) were male, and nearly half (46.4%) were pastoralists. The median patient, health system and total delays were 30 (19-48.5), 14 (4.5-29.5) and 50 (35-73.5) days, respec-tively. The median patient delay (35.5 days) and total delay (58.5 days) among pastoralists were substantially higher than the equivalent delays among non-pastoralists [p<0.001]. Of all, 3.8% of patients (16 of 18 were pastoralists) delayed longer than 6 months without initiating treatment. Factors associated with health system delay ≥15 days were mild symptoms [APR (95% CI) = 1.4 (1.1-1.7)], smear-negativity [APR (95% CI) = 1.2 (1.01- 1.5)], first visit to health centers [APR (95% CI) = 1.6 (1.3-2.0)] and multiple provider contacts [APR (95% CI) = 5.8 (3.5-9.6)]. Conclusion: Delay in diagnosis and treatment remains a major challenge of tuberculosis control targets in pastoralist settings of Ethiopia. Efforts to expand services tailored to transhumance patterns and diagnostic capacity of primary healthcare units need to be prioritized. © 2020 Getnet et al.Purpose: This study aimed to assess the extent of patient, health system and total delays in diagnosis and treatment of pulmonary tuberculosis (TB) in Somali pastoralist setting, Ethiopia.

Leaf traits variation of arabica coffee cultivars in response to population density and mineral nutrient

Open Access ArticleLeaf trait is good predictors of plant performance. It is closely associated with light requirement, growth and survival of the plant. This study was designed to evaluate the effect of seedling planting density and fertilizer rate on leaf traits variation of two Arabica coffee cultivars under nursery conditions. It was conducted at Jimma Agricultural Research Center from (February 29 to October 29), 2018. A factorial experiment was used and treatments were arranged using completely randomized design with three replications. Treatments consisted of combinations of two Arabica coffee cultivars (74110 and 75227), four population densities (one, two, three and four plants per polythene tube) and three compound NPK (22:6:12 + Te) rates (control, 5g and 10g). The results showed that interaction between cultivar, population density and fertilizer was significantly (P ≤ 0.05) influenced LN, LPR and LAI, and highly significantly (P ≤ 0.01) influenced LWR and SLA. High planting density (PD2) with 5g of NPK enhanced LN and LPR in cultivar-74110 while conventional (PD1) with 5g of NPK enhanced LN and LPR in cultivar-75227. Highest value of LWR was recorded from high planting density (PD2) with 5g of NPK while maximum value of LAI and SLA was recorded from high planting density (PD3) with 5g of NPK for both cultivars. At early field planting time, coffee seedling with higher LAI and SLA are very important for efficiently capture and better utilization of solar energy or light as well as increase seedling growth. In general, planting high population density (PD3) and fertilized with 5 g of NPK seems sufficient to improve LAI and SLA of coffee seedlings. Therefore, the future research direction should be focused on the management for increase leaf traits under field conditions

Challenges in delivery of tuberculosis services in Ethiopian pastoralist settings: clues for reforming service models and organizational structures

BACKGROUND: The End-TB strategy aims to see a world free of tuberculosis (TB) by the coming decade through detecting and treating all cases irrespective of socioeconomic inequalities. However, case detections and treatment outcomes have not been as they should be in Somali pastoral settings of Ethiopia. Hence, this study aimed to explore the challenges that hinder the delivery and utilization of TB services in pastoral areas. METHODS: A qualitative study was conducted between December 2017 and October 2018 among pastoralist patients with delay of >/=2 months in seeking healthcare, healthcare providers and programme managers. Data were collected from different sources using 41 in-depth interviews, observations of facilities and a review meeting of providers from 50 health facilities. The data were transcribed, coded and analyzed to identify pre-defined and emerging sub-themes. ATLAS.ti version 7.0 was used for coding data, categorizing codes, and visualizing networks. RESULTS: Poor knowledge of TB and its services, limited accessibility (unreachability, unavailability and unacceptability), pastoralism, and initial healthcare-seeking at informal drug vendors that provide improper medications were the key barriers hindering the uptake of TB medical services. Inadequate infrastructure, shortage of trained and enthused providers, interruptions of drugs and laboratory supplies, scarce equipment, programme management gaps, lack of tailored approach, low private engagement, and cross-border movement were the major challenges affecting the provision of TB services for pastoral communities. The root factors were limited potential healthcare coverage, lack of zonal and district TB units, mobility and drought, strategy and funding gaps, and poor development infrastructure. CONCLUSION: In pastoral settings of Ethiopia, the major challenges of TB services are limited access, illicit medication practices, inadequate resources, structural deficits, and lack of tailored approaches. Hence, for the pastoral TB control to be successful, mobile screening and treatment modalities and engaging rural drug vendors will be instrumental in enhancing case findings and treatment compliance; whereas, service expansion and management decentralization will be essential to create responsive structures for overcoming challenges

Determinants of patient delay in diagnosis of pulmonary tuberculosis in somali pastoralist setting of Ethiopia : a matched case-control study

Background; : Healthcare-seeking behavior is the basis to ensure early diagnosis and treatment of tuberculosis (TB) in settings where most cases are diagnosed upon self-presentation to health facilities. Yet, many patients seek delayed healthcare. Thus, we aimed to identify the determinants of patient delay in diagnosis of pulmonary TB in Somali pastoralist area, Ethiopia.; Methods; : A matched case-control study was conducted between December 2017 and October 2018. Cases were self-presented and newly diagnosed pulmonary TB patients aged ≥ 15 years who delayed &gt; 30 days without healthcare provider consultation, and controls were patients with similar inclusion criteria but who consulted a healthcare provider within 30 days of illness; 216 cases sex-matched with 226 controls were interviewed using a pre-tested questionnaire. Hierarchical analysis was done using conditional logistic regression.; Results; : After multilevel analysis, pastoralism, rural residence, poor knowledge of TB symptoms and expectation of self-healing were individual-related determinants. Mild-disease and manifesting a single symptom were disease-related, and &gt;1 h walking distance to nearest facility and care-seeking from traditional/religious healers were health system-related determinants of patient delay &gt; 30 days [; p; &lt; 0.05].; Conclusion; : Expansion of TB services, mobile screening services, and arming community figures to identify and link presumptive cases can be effective strategies to improve case detection in pastoral settings
