Despite the considerable benefits of this test in the battle against the growing burden of communicable and non-communicable diseases, its rate of provision is low. This study aimed to assess the rate of peripheral blood smear examination service provision and its barriers among public hospitals in southern Ethiopia.Method: We have conducted a descriptive cross-sectional study from January 01 to March 31, 2019, among five public hospitals in Southern Ethiopia. We collected socio-demographic data from patients and healthcare providers. We prepared peripheral blood smears from 423 patients with abnormal complete blood cell count. We examined a wright’s stained peripheral blood smear under the microscope to identify abnormality in the morphology of blood cells. We conducted key informant interviews with healthcare providers. We assessed health facilities using a standard checklist. We did descriptive statistical analysis for quantitative data using Statistical Package for Social Sciences (SPSS) version 20.0 software. We transcribed, categorized, and thematically analyzed the qualitative data. We presented the results in tables and figures.Result: The rate of provision of peripheral blood smear examination service was 11.6% (n= 49). Nearly 90% of the eligible patients did not receive this service. Relatively better rate of service provision was seen among hospitals with essential resources for the service, and those participating in Hematology external quality assurance. Lack of training, shortage of laboratory supplies, and inadequate supportive supervision were identified as barriers to regularly provide peripheral blood smear examination service.Conclusion: Rate of peripheral blood smear examination service provision is low. A large proportion of eligible patients missed the deserved service. Adequate laboratory supplies, training, and continued supportive supervision should be considered to improve the provision of this service.","PeriodicalId":134553,"journal":{"name":"Advances in Hematology and Oncology Research","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123418216","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A systematic review","authors":"","doi":"10.33140/ahor.04.01.02","DOIUrl":"https://doi.org/10.33140/ahor.04.01.02","url":null,"abstract":"Objective: Assiduous depiction of recurrent pregnancy loss (RPL) in patients after in vitro fertilisation (IVF). Material and Method: Women undergoing IVF treatment who had experienced two or more consecutive pregnancy losses before 20 weeks’ gestation with or without a history of implantation failure. Systematic review resulting in specific data bases such as Pub Med and Cochrane data base. Results: Factors associated with RPL after IVF consist mainly genetic origin (approx. 30%) due to aneuploid embryos, followed by thrombophilia and autoimmune factors. Mainly predisposition factors associated with high risk of recurrent miscarriages include obesity, advanced maternal age, anatomic defects of the uterus and endocrine disorders. On the contrary, 10-15% of cases of RPL represent idiopathic origin (Unexplained RPL). The evaluation of preimplantation genetic testing (PGT) remains a controversial entity. Conclusion: The aim of our study is focusing on the pathophysiologic mapping, presented in current literature, concerning RPL after IVF. Although IVF procedures, including assisted hatching, PGT and immunologic therapy have been suggested to improve live birth rates, their efficacy is controversial, since the factors related to RPL after spontaneous abortion or IVF do not reveal any statistic differences. Additionally, assisted reproductive technique (ART) cannot be supported as a treatment intervention for couples with unexplained RPL, due to the lack of adequate clinical studies.","PeriodicalId":134553,"journal":{"name":"Advances in Hematology and Oncology Research","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125691464","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Zinc oxide is the most widely used nanoparticles. Nanoparticles could induce oxidative stress that eventually leads to cell toxicity, inflammation and hemolysis. Objectives: The objective of this study was to evaluate the hematological changes induced by Zn-O nano-particles and/or Cyclophosphamide in male rats. Materials and Methods: Twenty four adult male rats (Sprague Dawley) were grouped randomly into four groups of six rats each. Group I. Control group: Received 0.2 ml saline /day i.p. injection for 14 days (day by day), group II (CP group): Received CP 20 mg/kg/day body weight (b.w.) day by day for 14 days by intraperitoneal injection, Group III (nZnO group): Received nZnO (5 mg/kg)/day b.w., intraperitoneally for 14 days. Group IV (CP + ZnO NPs group): Received nZnO group: Received nZnO (5 mg/kg/day) b.w., intraperitoneally for 14 days, plus CP 20mg/kg/day body weight (b.w.) day by day for 14 days by intraperitoneal injection. At the end of the experimental period, rats were anesthetized using light ether. Blood samples were taken for hematological evaluation. Results: Red blood cells count, hemoglobin concentration, and white blood cells count were significantly decline in rats treated with CP in comparison to control group, while combination of nZnO with CP reduced changes in red bood cells and hemoglobin values. Neutrophils, lymphocytes, eosinophils, and monocytes count were significantly decreased in CP-immunosuppressed group when compared with the control group. In CP-immunosuppressed animals treated with nZnO, these parameters were improved when compared with CP treated groups. Conclusion: It can be concluded that CP induced changes in the hematological parameters. Treatment of rats with zinc oxide nano-particles and CP together ameliorated the toxicity induced by CP. These results may provide further visions into proper treatment of patients by improving side effects of chemotheraby. However further studies are necessary to establish optimal doses of nZnO and receive the best safety profile.","PeriodicalId":134553,"journal":{"name":"Advances in Hematology and Oncology Research","volume":"94 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122698791","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

But treatment failure minimized these advantages and leads to an increment of morbidity and mortality with poor quality of life in all HIV patients. The aim at this study was to assess the prevalence of HIV-1 treatment failure and its determinants factors among children on first line HAART at Felegehiwot Referral Hospital. Methods: Cross sectional study was conducted on 238 children who had on first line HAART regimen using the inclusion criteria. Data were collected from patients’ chart starting from ART commencement (baseline data and other information) and interviewed using structured questionnaire. CD4 T-cells from whole blood and viral load from separated plasma were analyzed according to protocols. The collected data were analyzed using SPSS packages version 20. Descriptive statistics, odds ratio, bi-variate and multiple logistic regression analysis were used to show determinant factors association. Independent associations were considered with p<0.05. Result: Among the 238 participants enrolled, 137(57.6%) were females. The mean ages were 8.09 years and the median months on HAART from initiation were 51.93 months. A total of 25 (10.5%) participants were found to have virologic/treatment failure. The mean CD4 T-cells at base line were 342.33 cells/ml and 672.13 cells/ml respectively. Long duration on treatment, sub-optimal drug adherence, conducting faith healing, high medication dosage and ambulatory functional status at baseline were found to be significant predictors of treatment failure and showed positive odds ratio. Conclusion: This study demonstrates high virologic failure and the determinant factors of virologic failures among HAART first line children are still changing. Therefore, evidence-based intervention and early detection of treatment failure must be made to further identify the potential causes and set standardized protective mechanisms of virologic failures.","PeriodicalId":134553,"journal":{"name":"Advances in Hematology and Oncology Research","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127515375","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Predisposing conditions include catastrophic antiphospholipid syndrome (APS), atypical thrombotic thrombocytopenic purpura (TTP), delayed heparin-induced thrombocytopenia and Trousseau syndrome. Patients who do not meet any of these criteria are diagnosed with idiopathic catastrophic thrombotic syndrome. Case description: A 44-year-old Caucasian woman with type II diabetes and hypothyroidism presented with acute onset of myalgia and extensive bruising over a period of four days. Physical exam revealed hypotension, tachycardia, and extensive purpuric and bullous skin lesions. Laboratory evaluation demonstrated microangiopathic hemolysis, thrombocytopenia, elevated D-dimer and coagulopathy suggesting disseminated intravascular coagulation (DIC) along with acute kidney injury (AKI) and transaminitis. Aggressive transfusions including packed red blood cells, fresh frozen plasma, platelets and cryoprecipitate were required to reverse her severe coagulopathy. Ultrasound showed occlusive thrombus in the left basilic vein and the greater saphenous veins bilaterally and heparin infusion was started. IV methylprednisolone, all-trans retinoic acid and doxycycline were empirically given. Workup was negative for any coagulation factor deficiency or hypercoagulable state although heterozygous factor V Leiden (FVL) mutation was found. Bone marrow biopsy was normal. Infectious and auto-immune workups were unremarkable. Skin biopsy showed diffuse intravascular thrombi but no evidence of vasculitis. Two weeks later, she developed Enterobacter bacteremia from infection of her bullous lesions. She was started on broad spectrum antibiotics and transferred to a burn unit. Eventually, her coagulopathy, bacteremia, AKI and transaminitis resolved, she was discharged with indefinite anticoagulation. Discussion: CTS presented in our patient with rapidly progressive thrombosis with consumptive coagulopathy. No obvious instigating source was found, her clinical presentation was out of proportion for the isolated heterozygous FVL mutation. Anticoagulation remained the main therapy in the acute setting and aggressive supportive care in multi-disciplinary setting to manage acute and late complications was required. Conclusion: Through this report, we emphasize the need for early recognition of CTS with this constellation of clinical findings and advocate for urgent interventions to prevent untoward outcomes.","PeriodicalId":134553,"journal":{"name":"Advances in Hematology and Oncology Research","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122194575","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hence, a biomarker to predict the progression of cancer is needed. Plasminogen activator inhibitor-1 (PAI-1) has been known as one of the prognostic factors. However, in vivo studies indicated that PAI-1 has controversial roles. Whether PAI-1 suppresses or promotes the development of cancer, is still being the question. The study aims to examine the role of PAI-1 in predicting the survival rate and its association with clinicopathologic factors in advanced breast cancer. Materials and Methods: The historical cohort analytic method in advanced breast cancer patients was conducted at Dharmais National Cancer Center Hospital. Clinical data were obtained from patients’ medical records. The expression of PAI-1 was assessed through immunohistochemistry assay staining of breast cancer tissue using antibody PAI-1 Santa Cruz Biotechnology, Inc., PAI-1 C-9 sc5297. Survival analysis was done to obtain the prognostic data. Moreover, its association with clinicopathologic factors was analyzed. Results: Fifty-eight subjects were included in this study. There was a significant association between the expression of PAI-1 and survival rate (hazard ratio [HR] = 4.08, 95% confidence interval [CI] = 1.75 - 9.50, p = 0.001). The Kaplan-Meier method indicated significant differences in survival rate between subjects with high expression of PAI1 and those with low expression in advanced breast cancer (p = 0.001). PAI-1 expression had a sensitivity of 84.7% and specificity of 60% based on immunohistochemical score cut off of 90. Furthermore, the expression of PAI-1 showed no significant association with clinicopathological factors except for histopathology grade. (Relative risk [RR] = 1.5, 95%, CI = 1.2 - 1.8, p = 0.047).

This type of tumor commonly arises in sun-exposed areas, such as head, neck, and lower extremities. Here, we describe a rare presentation of non-indolent proliferative type Merkel cell carcinoma. Case Report: This is a case-report of a 70-year-old Caucasian man with no pertinent past medical history, presenting as a large painless violaceous necrotic irregular bordered rapidly growing lesion, reaching to 8x10x15 cm3, within one-year period, on the lower back region with surface ulceration. Pelvic MRI showed a multilobulated enhancing soft tissue mass measuring 8.7x10.4x15.1 cm3 at the left gluteal region with exophytic extension to the left paraspinal muscles. The patient was admitted, tangential surgical excision and debridement of left flank wound was performed with partial primary closure. Pathology showed features of Merkel cell, show diffuse dot-like positivity with CK20 and are negative for CK7, there is diffuse positivity with NSE, synaptophysin and CD56 with strong diffuse Ki-67 positivity noted in >65% of tumor cells. CD99 shows diffuse small faint dot-like paranuclear positivity. Discussion: Merkel cell carcinoma (MCC) is a rare, aggressive tumor that generally arises in sun-exposed regions. After an initial course of slow growth, starting as a painless violaceous non-pruritic domed-shaped lesion, the tumor becomes more aggressive, rapidly growing, with metastasis with local lymph nodes and regional tissue invasion. Sixty percent of tumors can rapidly grow within a three-month period after initial diagnosis. MCC is also clonally associated with is polyomavirus. MCC Contributing molecular pathogenesis is imperative to determining the causation of rare non-indolent MCC tumors, and its association with prognosis and treatment. In polyomavirus negative patients, consideration for molecular pathogenesis as etiology is imperative.","PeriodicalId":134553,"journal":{"name":"Advances in Hematology and Oncology Research","volume":"54 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114091540","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
