Modeling Time to Cure of Deep Vein Thrombosis Using Cox Proportional Model in Southwest of Ethiopia

BackgroundGlobally, there are about 10 million cases of deep vein thrombosis every year, and it is the third leading cardiovascular disease after myocardial infarction and stroke. The objective of the study is to assess risk factors of time to cure patients of deep vein thrombosis in southwest Ethiopia.MethodsA retrospective cohort study design was used. The study population was deep vein thrombosis patients at purposively selected hospitals in Southwest Ethiopia from January 2017 to December 2020. Cox proportional hazard model was used to identify risk factors associated with deep vein thrombosis.ResultsOut of the total 1068 registered as deep vein thrombosis patients, 263(24.6%) were cured during the study period, and 805(75.4%) were censored. Results of the Cox proportional hazard model show that; age, gender, family history of deep vein thrombosis, smoking status, immobilize and alcohol consumption were factors associated with deep vein thrombosis (p-value<0.05).ConclusionThe patients with a family history of deep vein thrombosis, prolonged immobilization, greater the 50 years, smoking cigarettes, female (non-pregnant) and alcohol users had a longer curing time of deep vein thrombosis compared to others.     

Bacteraemia among severely malnourished children in jimma university hospital, ethiopia

Background

Sever acute malnutrition severely suppresses every component of the immune system leading to increased susceptibility and severity to infection. However, symptoms and signs of infections are often unapparent making prompt clinical diagnosis and early treatment very difficult. The aim of the study was to determine the magnitude of bacteraemia and antimicrobial sensitivity among severely malnourished children.

Methods

Severely malnourished children admitted in Jimma University Specialized Hospital were enrolled between October, 2009 to May, 2010. Blood samples were collected, processed and bacterial isolates were identified using standard bacteriological procedures. Then, antibiotic susceptibility pattern of the isolates was determined by using Kirby-Bauer technique.

Results

Bacteraemia was seen in 35 (20.6%) of the 170 study subjects. There were a total of 35 bacterial isolates, Gram positive bacteria constitute 24(68.6%) of the isolates, where Staphylococcus aureus was the leading Gram positive isolate while Klebsiella species were the dominant Gram negative isolates. Twelve (7.1%) children died and 4 (33.3%) of them had bacteraemia. While susceptibility was more than 80% to Gentamicin, Ciprofloxacin and Ceftriaxone, increased level of resistance was documented to commonly used antibiotics, such as Amoxycillin, Co-trimoxazole and Chloramphenicol.

Conclusion

High prevalence of bacteraemia with predominating Gram positive isolates and increased level of resistance to commonly used antibiotics was shown among severely malnourished children in Jimma. Further studies are required to revise the current guideline for antibiotic choice.     

Conformational changes in the A3 domain of von Willebrand factor modulate the interaction of the A1 domain with platelet glycoprotein Ib

Bitiscetin has recently been shown to induce von Willebrand factor (vWF)-dependent aggregation of fixed platelets (Hamako J, et al, Biochem Biophys Res Commun 226:273, 1996). We have purified bitiscetin from Bitis arietans venom and investigated the mechanism whereby it promotes a form of vWF that is reactive with platelets. In the presence of bitiscetin, vWF binds to platelets in a dose-dependent and saturable manner. The binding of vWF to platelets involves glycoprotein (GP) Ib because it was totally blocked by monoclonal antibody (MoAb) 6D1 directed towards the vWF-binding site of GPIb. The binding also involves the GPIb-binding site of vWF located on the A1 domain because it was inhibited by MoAb to vWF whose epitopes are within this domain and that block binding of vWF to platelets induced by ristocetin or botrocetin. However, in contrast to ristocetin or botrocetin, the binding site of bitiscetin does not reside within the A1 domain but within the A3 domain of vWF. Thus, among a series of vWF fragments, 125I-bitiscetin only binds to those that overlap the A3 domain, ie, SpIII (amino acid [aa] 1-1365), SpI (aa 911-1365), and rvWF-A3 domain (aa 920-1111). It does not bind to SpII corresponding to the C-terminal part of vWF subunit (aa 1366-2050) nor to the 39/34/kD dispase species (aa 480-718) or T116 (aa 449-728) overlapping the A1 domain. In addition, bitiscetin that does not bind to DeltaA3-rvWF (deleted between aa 910-1113) has no binding site ouside the A3 domain. The localization of the binding site of bitiscetin within the A3 domain was further supported by showing that MoAb to vWF, which are specific for this domain and block the interaction between vWF and collagen, are potent inhibitors of the binding of bitiscetin to vWF and consequently of the bitiscetin-induced binding of vWF to platelets. Thus, our data support the hypothesis that an interaction between the A1 and A3 domains exists that may play a role in the function of vWF by regulating the ability of the A1 domain to bind to platelet GPIb.     

Is Coil Embolization of Hypogastric Artery Necessary during Endovascular Treatment of Aortoiliac Aneurysms?

The aim of this study was to evaluate the safety and efficacy of stent graft coverage of hypogastric artery in the management of aortoiliac aneurysms. Between January 2000 and December 2002, 98 patients underwent endovascular repair of aortoiliac aneurysms (EVAR). Of these, 24 (24.5%) required occlusion of one hypogastric artery to facilitate the endovascular repair. Based on the method of hypogastric artery occlusion, patients were divided in to two groups. Group A (13/24 = 54%) underwent standard coil embolization followed by hypogastric artery orifice coverage whereas group B (11/24 = 46) underwent hypogastric artery orifice coverage without coil embolization. Post-EVAR computed tomographic angiography (CTA) was used to determine occurrence of endoleaks from the hypogastric artery orifice and patency of superior gluteal artery in both groups. These findings were further correlated with presence or absence of gluteal claudication. There was no difference in age (p < 0.38) or iliac aneurysm size (p < 0.3). In group A (13 patients), occlusion of superior gluteal artery was seen in 6 (46%). Four of six (66%) patients developed severe gluteal claudication. Patients in group A were likely to require more than one intervention (p < 0.00036). No patients in group B developed occlusion of the superior gluteal artery (p < 0.04) or gluteal claudication (p < 0.046). No endoleaks were seen from the origins of hypogastric artery in either group. The follow-up period ranged from 2 to 35 months. Hypogastric artery orifice coverage without coil embolization effectively prevented retrograde endoleak without the occurrence of disabling gluteal claudication. Coil embolization of the hypogastric artery may be unnecessary during treatment of aortoiliac aneurysm.Presented at the Twenty-eighth Annual Meeting of the Peripheral Vascular Surgery Society, Chicago, IL, June 7, 2003.     

A novel antibacterial iridoid and triterpene from Caiophora coronata

Bioassay-guided fractionation of the antibacterial CH(2)Cl(2)-MeOH extract obtained from the aerial parts of the Argentinean plant Caiophora coronata led to the isolation of a new triterpene, 1beta,3beta-dihydroxyurs-12-en-27-oic acid, 1, and a new iridoid, 1alpha-methoxy-6alpha,10-dihydroxyisoepiiridomyrmecin (caiophoraenin), 2, along with the known iridoid isoboonein 3. Their structures were established by spectroscopic techniques (1D and 2D NMR, HRFABMS, FTIR). The MIC values of isolated compounds were determined against methicillin-sensitive (MSSA) and -resistant (MRSA) strains of Staphylococcus aureus, Bacillus subtilis (BS), vancomycin-resistant Enterococcus faecium (VREF), Escherichia coli (EC), E. coli imp (ECimp), and Candida albicans (CA). Compound 1 was found active against BS, MSSA, MRSA, VREF, and ECimp with MIC values of 2, 4, 4, 4, and 16 microg/mL, respectively.     

The utility of pallor detecting anemia in under five years old children

The diagnosis and management of anemia, which affects a significant proportion of young children in developing countries, largely depends on the clinical assessment for pallor. This study was conducted with the aim of evaluating the utility of pallor in detecting anemia. Children aged 2 to 60 months who visited the pediatric outpatient department of Jimma Hospital over 3 months period were assessed for the presence and degree of pallor in 4 anatomic sites (conjunctivae, tongue and buccal mucosa, nailbeds, palm) by trained nurses. Hemoglobin was then determined using the HemoCue method. Individuals involved in clinical examination did not have access to the laboratory results before documenting their findings. The mean hemoglobin in the 574 children examined was 11.03 gm/dl, and about 46% had anemia. Children younger than 2 years were found to have a higher prevalence of anemia as compared to older children (p < 0.001). Palmar pallor, with a sensitivity of 58%, had the highest sensitivity to detect moderate anemia as compared to other anatomic sites. The presence of either palmar or conjunctival pallor increased the sensitivity to 73%. The inter-observer agreement was highest for conjunctival pallor (kappa value = 0.81). The findings of the study suggest that pallor of a single anatomic site does not have adequate sensitivity to detect moderate anemia. We recommend further studies to look at the performance of severe pallor in correctly identifying severe anemia. Furthermore, the magnitude and causes of anemia need to be studied in a community setting.
