BackgroundOrgan transplantation is considered one of the greatest advances of modern science, and it has given many patients a renewed lease on life. The demand for organs far exceeds the supply. Health professionals are fundamental in the process of organ procurement.ObjectiveTo assess the attitude, willingness, and associated factors in organ donation among health professionals of Gondar, Ethiopia.MethodsOur cross-sectional study was conducted among 382 randomly selected health professionals in Gondar using a self-administered questionnaire. Multivariable logistic regression analysis was applied to analyze the data.ResultsAmong health professionals, 79.1% had favorable attitude toward organ donation and 74.6% were willing to donate their organs. After adjusting for covariates, the odds of having a favorable attitude about organ donation were 3.2 and 11.9 times higher in the professions of laboratory technologists and medical doctors, respectively. By keeping all other variables constant, attitude was found to be positively associated with awareness (adjusted odds ratio [aOR] 12.74, 95% confidence interval [CI] 3.71-43.8) and being a member of the Red Cross Association (aOR 5.24, 95% CI 1.46-18.96). Willingness was positively associated with awareness (aOR 6.25, 95% CI 2.0-19.53), a member of the Red Cross Association (aOR 5.09, 95% CI 1.5-17.22), a laboratory technologist (aOR 3.57, 95% CI 1.37-9.29), and a medical doctor (aOR 6.52, 95 % CI 1.93-22.01).ConclusionsThe main findings indicated that the majority of health professionals in Gondar had a favorable attitude toward organ donation and were willing to donate their organs in times of need.  相似文献

Beta lactam antibiotics were very effective against Streptococcus pneumoniae. However, resistance to this class of antibiotics has become an increasing problem. Reports of penicillin resistant and multidrug resistant strains are being made in many parts of the world. We examined the drug sensitivity pattern of S. pneumoniae isolates in a retrospective analysis of laboratory records of S. pneumoniae isolates between March 2001 and April 2005 at Gondar University Hospital, Ethiopia. A significant proportion of the isolates were found to be resistant to one or more of the commonly used antibiotics. Furthermore, the isolates appear to be acquiring an increasing resistance to crystalline penicillin, cotrimoxazole and ampicillin. This situation needs immediate attention.  相似文献

Febrile illnesses remain a major cause of morbidity and mortality in resource-poor countries, but too often, tests are not available to determine the causes, leading to misdiagnosis and inappropriate treatment. To determine the cause of febrile illnesses, we recovered the malaria smears from 102 children presenting with fever to Soddo Christian Hospital in Wolaitta Soddo, Ethiopia. DNA was isolated from the smears and evaluated by real-time polymerase chain reaction. We identified pathogen DNA with probes for Plasmodium spp., Streptococcus pneumoniae, Rickettsia spp., Salmonella spp., and Borrelia spp. Overall, we showed that it is possible to isolate high-quality DNA and identify treatable pathogens from malaria blood smears. Furthermore, our data showed that bacterial pathogens (especially Pneumococcus, Rickettsia spp., and Borrelia spp.) are common and frequently unrecognized but treatable causes of febrile illnesses in Ethiopian children.  相似文献

Introduction and hypothesis

The aim of this study was to gain in-depth knowledge of women suffering from urinary incontinence (UI) in rural and semiurban settings in Ethiopia.

Methods

A qualitative study based on semistructured in-depth interviews with 26 informants, 18 of whom were women experiencing the symptom of urinary leakage. The study was conducted in the Amhara Region of northwest Ethiopia and was part of the Dabat Incontinence and Prolapse (DABINCOP) study.

Results

Limited access to water, soap, pads, and spare clothes characterized daily management of the symptom. The consequences for marital relationships and social life were of great concern to the informants. Shame, embarrassment, and fear of being discriminated against led to huge efforts to hide the leakage. Among informants who were not able to hide it, humiliating comments and discriminatory behavior were commonly experienced, sometimes leading to divorce and self-isolation. Women who disclosed their symptom usually had a person who supported them. Women with UI regarded it as unnatural and uncommon. Most took no action to improve the situation, as they saw no options for help.

Conclusions

Several circumstances limited the opportunities available to women to keep themselves clean, disclose the problem to others, and access health information and health-care facilities. In order to understand how women in this setting practically handled, perceived, and experienced living with UI, it was essential to address contextualized and sociocultural dimensions related to the symptom.  相似文献

In this study, we report a green synthesis of MoS2 nanosheets (NSs) using a facile hydrothermal technique in the presence of l-cysteine. l-Cysteine can serve as a greener source of sulfur as well as a capping agent to help the growth of MoS2 nanosheets. The prepared materials were characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM) with energy dispersive spectroscopy (EDS), electron transmission microscopy (TEM), X-ray photoelectron microscopy (XPS), and Brunauer, Emmett, and Teller (BET) analysis. The results showed that MoS2 NSs are of high crystallinity with a lattice spacing of 0.61 nm. The optical bandgap of MoS2 NSs nanosheets prepared using l-cysteine as a source of sulfur was found to be 1.79 eV. The photocatalytic degradation of MoS2 NSs towards methylene orange (MO) and rhodamine blue (RB) dyes under sunlight was found to be promising for practical applications. The fast kinetics of degradation of MO and RhB was observed over a wide range of pH range. Moreover, MoS2 NSs showed excellent antifungal activities against Trichophyton mentagrophytes and Penicillium chrysogenum fungus.

BACKGROUND: Urinary tract infection (UTI) is one of the most common bacterial infections encountered by clinicians in developing countries. Although UTI seldom leads to complications, it can cause significant morbidity and mortality. OBJECTIVE: To identify the etiologic agents of UTIs and to assess their antimicrobial susceptibility pattern. METHODS: A retrospective analysis of 1420 mid-stream urine specimens processed fobr culture and antimicrobial susceptibility testing in the bacteriology laboratory of Gondar University Teaching Hospital between September 2002 and August 2003 was conducted RESULTS: Significant bacteriuria (cultures with > 10(5) colony forming units of bacteria per ml of urine) was observed in 399 (28.1%) of the specimens. Two bacteria each were isolated from 14 specimens, making the number of bacteria isolated to be 413 with the isolation rate of 29.1%. The most commonly isolated bacteria were Escherichia coli 166 (40.2%), Staphylococcus aureus 60 (14.5%), Klebisella species 42 (10.2%) and Citrobacter species 34 (8.2%). Among Gram-positive organisms S. aureus showed high level qf drug resistance for tetracycline 48 (80%), corimoxazole 32 (53.3%), chloramphenicol 32 (53.3%), amnpicillin 26 (43.3%) and penicillin 22 (36.7%). Of the Gram-negative bacteria, extremely high resistance patterns were found in Salmonella species for ampicillin 5 (100%), erythromycin 5 (100%), penicillin 5 (100%), co-trimoxazole 3 (60%), tetracycline 3 (60%) and 3 chloramphenicol (60%). Multiple drug resistance was observed in 85.7% of the isolates. Only 5.1% of the isolates were found to be sensitive to all antibiotics tested. CONCLUSION: Resistance to the commonly used antibiotics was found to be very high among the isolates leaving clinicians with very few choices of drugs or the treatment of UTIs. It is therefore, critical that the use of antimicrobial agents with in a hospital and all other responsible institutions he reviewed  相似文献

Brain metastases (BM) represent the most common tumor to affect the adult central nervous system. Despite the increasing incidence of BM, likely due to consistently improving treatment of primary cancers, BM remain severely understudied. In this study, we utilized patient-derived stem cell lines from lung-to-brain metastases to examine the regulatory role of STAT3 in brain metastasis initiating cells (BMICs). Annotation of our previously described BMIC regulatory genes with protein-protein interaction network mapping identified STAT3 as a novel protein interactor. STAT3 knockdown showed a reduction in BMIC self-renewal and migration, and decreased tumor size in vivo. Screening of BMIC lines with a library of STAT3 inhibitors identified one inhibitor to significantly reduce tumor formation. Meta-analysis identified the oncomir microRNA-21 (miR-21) as a target of STAT3 activity. Inhibition of miR-21 displayed similar reductions in BMIC self-renewal and migration as STAT3 knockdown. Knockdown of STAT3 also reduced expression of known downstream targets of miR-21. Our studies have thus identified STAT3 and miR-21 as cooperative regulators of stemness, migration and tumor initiation in lung-derived BM. Therefore, STAT3 represents a potential therapeutic target in the treatment of lung-to-brain metastases.  相似文献
