Activation Induced Cytidine Deaminase Expression in Patients with Myelodysplastic Syndrome and its Relationship with Prognosis and Treatment Background and Aim Activation induced cytidine deaminase (AID) enables antibody diversity in B lymphocytes. It may also have an effect on MDS pathogenesis by causing somatic mutations and by inducing epigenetic changes in myeloid cells. This study aimed to compare AID expression of MDS patients with healthy controls, of MDS patients in different risk groups and of MDS patients according to their treatment.
Total RNA was isolated and complementary DNA (cDNA) was transcribed from the peripheral blood samples of MDS patients and healthy controls. AID and the reference gene HPRT1 were analysed using Quantitative Real-time PCR(QRT-PCR). AID expression relative to HPRT1 was calculated. Patients were classified into "lower risk" and "higher risk" subgroups according to their initial IPSS and IPSS-R scores and their MDS subtypes at the time of study. Patients were also divided expression is not significantly different in "lower risk" and "higher risk" subgroups and in patients treated with hypomethylating agents. Increased AID expression may be an early step in MDS pathogenesis.
The outbreak of coronavirus disease 2019 (COVID-19) has been an almost global pandemic with significant public health impacts. The increasing prevalence of malignancy has become a leading cause of human mortality. However, conflicting findings have been published on the association between malignancy and COVID-19 severity. This study aims to assess the pooled proportion of malignancy amongst 2019-nCov patients and to investigate the association between malignancy and COVID-19 severity.
Correlative studies were identi?ed by systematically searching electronic databases (PubMed, Web of Sciences and Embase) up to September 2, 2020. All data analyses were carried out using Stata 15.0.
Twenty-nine studies consisting of 9475 confirmed COVID-19 patients (median age 54.4 years [IQR 49-62], 54.0% men) were included. The overall proportion of malignancy was 2.5% (95% CI 1.6%-3.4%). The proportion of malignancy was higher in patients with severe/critical 2019-nCoV than those in non-severe/non-critical group (3.9% [95% CI 2.0-6.3] vs 1.4% [95% CI 0.8-2.2]). Furthermore, pre-existing malignancy was associated with more than twofold higher risk of severe/critical patients with COVID-19 (OR 2.25, 95% CI 1.65-3.06 I2 = 0.0%).
Malignancy was associated with up to 2.3-fold higher risk of severe/critical COVID-19 and may serve as a clinical predictor for adverse outcomes.

Common variable immunodeficiency (CVID) characterized by defective immunoglobulin production is the most prevalent form of symptomatic primary immunodeficiency (PID) in adults. We aimed to reveal the clinical features of adults with CVID and to evaluate the effects of immunoglobulin replacement treatment (IRT) on hemato-immunological findings.
This study included 26 adult patients receiving IRT. Two measurements of complete blood counts and major immunoglobulin levels measured at the beginning-end of follow-up period were used for comparisons. Lymphocyte subsets and B-cell subgroups were measured only at the time of presentation.
The most common complications were related to respiratory and digestive systems, and organomegaly. Chronic diarrhoea and low body weight were positively correlated with the percentage of CD8+ T cells (P=0.019 and P=0.003 respectively) but negatively correlated with the CD4/CD8 ratio and the percentage of CD19+ B cells (P=0.019 and P=0.005 for both parameters, respectively). At the end of period, the distribution of haematological parameters significantly improved, and immunoglobulin M (IgM) level increased to detectable levels (P=0.035).
There are apparent relationships among chronic diarrhoea and low body weight, and deterioration of T and B cell immunity in adults with CVID. IRT improves the whole blood parameters and stimulates IgM production. The later effect supports the immunomodulatory feature of this therapy.

Thalamus infarctions presented with various clinical findings are considered to be related to classical and variative infarction areas.
In our study, we aimed to compare the sequela clinical findings of patients with isolated thalamus infarction according to anatomical areas.
70 patients diagnosed with isolated thalamus infarction in our clinic between 2010 and 2020 were included in the study. The infarction areas of the patients were divided into groups by the radiologist, including the variative areas to the classical areas using magnetic resonance imaging. Neurological examinations were performed and recorded by the neurologist. Sequela clinical findings of the groups were compared.
The mean age of all patients was 64.49 ± 13.75 years (range between 33-81), and the female ratio was 52.9% (n 33). Selleckchem Dansylcadaverine Inferolateral area infarction was detected most commonly. The most common complaints were sensory complaints (48.6%), speech disorders (20%), limb weakness (15.7%). There were no significant association between the neurological examination findings of classical and variative area infarctions of patients whose most common admission complaint is sensory deficits (p <0.05), and significant signs of cognitive impairment were detected in the anterior area compared to other areas (p<0.001).It can be considered that cognitive impairment findings we detected in the anterior area developed due to its associations.
In our study where sequela findings were evaluated, the absence of a significant difference in neurological examination findings can be explained by the decline of many acute clinical findings over time.
