espite the limitations of studying a syndrome that can only occur in a small, discrete population, we present a thorough overview of the literature surrounding SANS and several key areas important for future research are identified.

Human immunodeficiency virus and anemia are the major public health problems in Sub-Sahara Africa. Untreated anemia is associated with rapid progression and poor prognosis of the disease in HIV. This study was aimed at determining the magnitude, severity and associated factors of anemia among HIV infected patients taking zidovudine and tenofovir-containing first-line HAART in Ayder Comprehensive Specialized Hospital, Mekele, Ethiopia.

A case-control study was conducted from February to August 2019 using both convenient and quota sampling methods. Anemia is defined as hemoglobin value below 13 g/dl for male and below 12 g/dl for female. Sociodemographic and clinical characteristics were assessed using a structured questionnaire, medical records, electronic weighing scale, adult height board, automated hematology analyzer (Sysmex XT-4000i), and Becton Dickinson’s FACS caliber flow cytometer. Descriptive statistics, tables, graphs, Student’s

-test and l logistic regression were used to analyze the data.

risks of anemia in both types of regimens.

We find that the prevalence of anemia was significantly higher among patients taking ZDV-containing regimen. But different risk factors for anemia had been identified among ZDV-containing regimen, showing that appropriate follow-up, nutritional supplementation, continuous evaluation of patients on cotrimoxazole intake can reduce the risks of anemia in both types of regimens.

Hemoglobinopathies are common disorders in Saudi Arabia and have an impact on the general health of the affected individuals. The current study aimed to find out the effects of the presence of α 3.7 kb rightward deletion or sickle-cell trait (SCT) on ventilatory and hemodynamic parameters of maximum exercise testing in young Saudi women.

In a cross-sectional study, 75 randomly selected female students from different colleges were tested for VO

using a COSMED system for maximum exercise testing. Blood parameters and globin genotyping were determined.

Hemoglobin genetic studies revealed 28 of the students had 3.7 α-globin deletion only (

α

), five had SCT, and 42 had normal α-globin (α

and no HbS) and were considered the control group. Subjects with

α

/α

α

showed significantly lower VO

and higher resting systolic blood pressure, while SCT carriers showed no difference in regard to ventilatory parameters, but had higher post-exercise systolic blood pressure than controls.

It is concluded that individuals with 3.7 α-globin deletion might have lower fitness capacity, as demonstrated by lower VO

, which might explain the general lower VO

in the young women of this population. Furthermore, increments in resting systolic and posteexercise systolic blood pressure in 3.7 α-globin deletion and SCT, respectively, might indicate a future risk of cardiovascular diseases and require attention and extensive studies.

Furthermore, increments in resting systolic and posteexercise systolic blood pressure in 3.7 α-globin deletion and SCT, respectively, might indicate a future risk of cardiovascular diseases and require attention and extensive studies.

Acute promyelocytic leukemia (APL) constitutes 5-10% of all cases of newly diagnosed acute myeloid leukemia. However, data on the epidemiology and risk factors for acute kidney injury (AKI) in patients with newly diagnosed APL are lacking. This study determined the incidence rate of AKI during induction chemotherapy for patients with newly diagnosed APL and the risk factors for AKI.

We conducted a retrospective observational study of patients with newly diagnosed APL in the Shonan Kamakura General Hospital between April 2004 and April 2020. Data of 27 patients with newly diagnosed APL were analyzed. BEZ235 PI3K inhibitor The patients were classified as no AKI and AKI stages 1, 2 or 3.

The incidence rate of AKI during induction chemotherapy was 40% (11/27). Among patients who developed AKI, four patients experienced AKI stage 3, and two patients required renal replacement therapy. No significant differences were found in the white blood cell count and baseline renal function between the groups; however, D-dimer and C-reactive should be avoided in patients with newly diagnosed APL, and using alternative non-nephrotoxic drugs should be considered for patients at risk of AKI.

Blood is arranged into four groups based on their surface antigen (A, B, AB, and O). In addition to this classification based on the Rhesus factor, each blood group clustered into RH positive and RH negative. This study was done to identify the distribution of blood group and rhesus factors on the local blood bank.

To identify the frequency of ABO blood group and RH factors distribution on voluntary blood donator at Debre Tabor blood bank from May 2014 to May 2020.

A retrospective cross-sectional survey was conducted to identify the frequency of ABO and Rh factor distribution on voluntary blood donors at Debre Tabor town blood bank. The data was collected at Debre Tabor blood bank. A six-year data and a total of 19,901 bags collected blood samples were used for summarization of the data. The data was analysed by using SPSS version 21.

Blood group “O” was the dominated one with 39.6% followed by blood group “A”, “B” and “AB” with 29.48%, 24.06%, and 6.7%, respectively. When we see the RH classifications, RH positive accounts the highest percentage 92.77% and the remaining 7.23% was Rh negatives.

In this survey, the majority of blood groups were found “O” followed by “A”, “B”, and “AB”. Among the collected blood unities, 92.77% was RH positive. The leading blood donators were male.
