Use of Mindray MC-80 digital morphology analyzer’s estimated platelet counts as adjunct to automated hematology analyzer

Introduction: Automated hematology analyzer platelet counts can be performed using either the impedance (PLT-I) method or the fluorescent nucleic acid staining (PLT-O) method. Estimated platelet counts (PLT-E) can be calculated using a digital morphology analyzer by evaluating the peripheral blood smear. Our objective was to compare the platelet values detected on a Mindray BC-6200 device to the PLT-E count on a Mindray MC-80 digital morphology analyzer. Material and methods: Complete blood cell count findings between 1 September and 11 October, 2022 were obtained from the data storage units of the devices. We selected two groups of blood: a first group with thrombocytopenia (n = 49) and a second group that gave an aggregation and/or platelet clumping flag (n = 32). The results of 190 consecutive patients with normal platelet counts, and no aggregation flag, were evaluated as a control group. Pearson’s correlation coefficients, Bland-Altman plots, and paired t-tests were calculated. Results: The plot of the difference between PLT-I and PLT-O counts showed that the mean difference was –43.6 (95%: –17.2 to –69.9); when we compared PLT-O to PLT-E, bias was improved to –6.1 (95%: –18.26 to 6.1) in samples with aggregation and/or clumping flags (Bland-Altman plots). In samples with thrombocytopenia without aggregation and/or clumping, on the Bland-Altman plot, the differences in means were all close to zero, and there were no definite biases. Conclusions: Examining blood samples using the Mindray MC-80 digital morphology analyzer system on samples that show platelet clumps has the potential to improve PLT-I results in day-to-day laboratory routine

Recent Advances in Health Biotechnology During Pandemic

The outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which emerged in 2019, cut the epoch that will make profound fluctuates in the history of the world in social, economic, and scientific fields. Urgent needs in public health have brought with them innovative approaches, including diagnosis, prevention, and treatment. To exceed the coronavirus disease 2019 (COVID-19) pandemic, various scientific authorities in the world have procreated advances in real time polymerase chain reaction (RT-PCR) based diagnostic tests, rapid diagnostic kits, the development of vaccines for immunization, and the purposing pharmaceuticals for treatment. Diagnosis, treatment, and immunization approaches put for- ward by scientific communities are cross-fed from the accrued knowledge of multidisciplinary sciences in health biotechnology. So much so that the pandemic, urgently prioritized in the world, is not only viral infections but also has been the pulsion in the development of novel approaches in many fields such as diagnosis, treatment, translational medicine, virology, mi- crobiology, immunology, functional nano- and bio-materials, bioinformatics, molecular biol- ogy, genetics, tissue engineering, biomedical devices, and artificial intelligence technologies. In this review, the effects of the COVID-19 pandemic on the development of various scientific areas of health biotechnology are discussed

Effects of immunosuppressive drugs on COVID-19 severity in patients with autoimmune hepatitis

Background: We investigated associations between baseline use of immunosuppressive drugs and severity of Coronavirus Disease 2019 (COVID-19) in autoimmune hepatitis (AIH). Patients and methods: Data of AIH patients with laboratory confirmed COVID-19 were retrospectively collected from 15 countries. The outcomes of AIH patients who were on immunosuppression at the time of COVID-19 were compared to patients who were not on AIH medication. The clinical courses of COVID-19 were classified as (i)-no hospitalization, (ii)-hospitalization without oxygen supplementation, (iii)-hospitalization with oxygen supplementation by nasal cannula or mask, (iv)-intensive care unit (ICU) admission with non-invasive mechanical ventilation, (v)-ICU admission with invasive mechanical ventilation or (vi)-death and analysed using ordinal logistic regression. Results: We included 254 AIH patients (79.5%, female) with a median age of 50 (range, 17-85) years. At the onset of COVID-19, 234 patients (92.1%) were on treatment with glucocorticoids (n = 156), thiopurines (n = 151), mycophenolate mofetil (n = 22) or tacrolimus (n = 16), alone or in combinations. Overall, 94 (37%) patients were hospitalized and 18 (7.1%) patients died. Use of systemic glucocorticoids (adjusted odds ratio [aOR] 4.73, 95% CI 1.12-25.89) and thiopurines (aOR 4.78, 95% CI 1.33-23.50) for AIH was associated with worse COVID-19 severity, after adjusting for age-sex, comorbidities and presence of cirrhosis. Baseline treatment with mycophenolate mofetil (aOR 3.56, 95% CI 0.76-20.56) and tacrolimus (aOR 4.09, 95% CI 0.69-27.00) were also associated with more severe COVID-19 courses in a smaller subset of treated patients. Conclusion: Baseline treatment with systemic glucocorticoids or thiopurines prior to the onset of COVID-19 was significantly associated with COVID-19 severity in patients with AIH.Fil: Efe, Cumali.

SAĞLIK BİLİMLERİ ALANINDA ULUSLARARASI AKADEMİK ÇALIŞMALAR VE TEORİK BİLGİLER 1

Saldırganlık, bireyin hayatta kalması ve yaşambölgesini veya kaynaklarını koruması için gerekli ancak uygunsuz bir şekildeifade edildiğinde yıkıcı olabilen karmaşık bir sosyal davranıştır (Aleyasin veark., 2018; Zhang, 2021). Çeşitli davranış kalıplarını kapsar ve kökenleri,ifadeleri ve işlevleri açısından çok boyutludur. Tanımına bakılacak olursagenel olarak “zarar veren ve yaralayan veya bunu yapmakla tehdit eden davranış”veya “kaçınmakta olan başka bir canlıya zarar verme veya yaralama amacınayönelik herhangi bir davranış biçimi” olarak tanımlanır. Böcekler, balıklar,kertenkeleler, kurbağalar ve insanlar gibi gruplar halinde yaşayan türlerdebarışı korumak ve sosyal etkileşimleri düzenlemek için saldırganlık davranışıgözlemlenir (Takahashive Miczek, 2014; Zhang, 2021).Evcil hayvanlar göz önüne alındığında, insana yönelik köpek saldırganlığıen yaygın ve en ciddi davranış sorunudur ve evcil hayvan sahiplerinineğitmenlerden ve veterinerlerden profesyonel yardım almalarının bir numaralınedenidir. Bu problemin çözümü açısından korkuya bağlı saldırganlık, cinsiyetebağlı saldırganlık, ırk ve kalıtsal saldırganlık, kaynak koruma (sahiplenmesaldırganlığı), çatışmaya bağlı saldırganlık (baskınlık saldırganlığı), annesaldırganlığı gibi bir sınıflandırma oluşturulmuştur. Bölgesel saldırganlık(Luescher ve ark., 2008; Whittle ve ark., 2011; Kaneo ve ark., 2013). Bununlabirlikte, tipik saldırgan davranış kalıpları türler arasında farklılıkgösterir, kemirgenler, primatlar ve hayvanlar arasındaki saldırganlığınnörobiyolojisi ve nöroanatomisinde bazı benzerlikler vardır. Bu kitap bölümünde,MRI taramaları, immünohistokimyasal boyamalar ve çeşitli beyin bölgelerininelektriksel uyarımından elde edilen güncel veriler ışığında saldırganlığınoluşum mekanizmasının karşılaştırmalı nöroanatomisi araştırılmıştır.</p
