A Drug Screening Reveals Minocycline Hydrochloride as a Therapeutic Option to Prevent Breast Cancer Cells Extravasation across the Blood-Brain Barrier.

Among breast cancer (BC) patients, 15-25% develop BC brain metastases (BCBM), a severe condition due to the limited therapeutic options, which points to the need for preventive strategies. We aimed to find a drug able to boost blood-brain barrier (BBB) properties and prevent BC cells (BCCs) extravasation, among PI3K, HSP90, and EGFR inhibitors and approved drugs. We used BCCs (4T1) and BBB endothelial cells (b.End5) to identify molecules with toxicity to 4T1 cells and safe for b.End5 cells. Moreover, we used those cells in mixed cultures to perform a high-throughput microscopy screening of dru

The risk of early and late CMV DNAemia associated with Campath use in stem cell transplant recipients.

The risks associated with in vivo and ex vivo use of Campath-1H and -1G in a cohort of 206 stem cell transplant recipients for human CMV (HCMV) DNAemia have been quantified. DNAemia showed a biphasic incidence pattern with an inflexion at day 60. The first phase had a linear risk rate for HCMV DNAemia of 0.3% per day, whereas the second phase had a substantially lower risk rate of 0.058% per day. In multivariable analyses, risk factors for early DNAemia were HCMV serostatus, radiotherapy-based conditioning and CD34 stem cell dose, with the use of in vivo Campath-1H having the most significant

A case report of fludarabine associated ectopic atrial bradycardia and literature review of fludarabine induced bradycardia.

BACKGROUND: Fludarabine is a chemotherapeutic agent with lymphodepleting effects that is increasingly used as part of a conditioning regimen prior to allogeneic stem cell transplantation. Fludarabine is generally considered a relatively safe medication with only rare cases of cardiotoxic side effects. CASE PRESENTATION: Here, we present a case of a 30-year-old woman who was undergoing conditioning for a haploidentical cell transplantation for treatment of Fanconi anemia with a 5-day course of daily fludarabine infusion. After her second fludarabine infusion, she was noted to have ectopic atri

Clinical Characteristics and Outcomes of COVID-19 in Turkish Patients with Hematological Malignancies

ObjectivePatients with solid malignancies are more vulnerable to severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection than the healthy population. The outcome of SARS-CoV-2 infection in highly immunosuppressed populations, such as in patients with hematological malignancies, is a point of interest. We aimed to analyze the symptoms, complications, intensive care unit admissions, and mortality rates of patients with hematological malignancies infected with SARS-CoV-2 in Turkey.Materials and methodsIn this multicenter study, we included 340 adult and pediatric patients diagnosed

Association of gender with outcomes in critically ill patients.

IntroductionThe influence of gender on mortality and other outcomes of critically ill patients is not clear. Different studies have been performed in various settings and patient populations often yielding conflicting results. We wanted to assess the relationship of gender and intensive care unit (ICU) outcomes in the patients included in the Acute Physiology and Chronic Health Evaluation (APACHE) IV database (Cerner Corporation, USA).MethodsWe performed a retrospective review of the data available in the APACHE IV database. A total of 261,255 consecutive patients admitted to adult ICUs in Uni

Seasonal clustering of sinopulmonary mucormycosis in patients with hematologic malignancies at a large comprehensive cancer center.

BackgroundInvasive Mucorales infections (IMI) lead to significant morbidity and mortality in immunocompromised hosts. The role of season and climatic conditions in case clustering of IMI remain poorly understood.MethodsFollowing detection of a cluster of sinopulmonary IMIs in patients with hematologic malignancies, we reviewed center-based medical records of all patients with IMIs and other invasive fungal infections (IFIs) between January of 2012 and August of 2015 to assess for case clustering in relation to seasonality.ResultsA cluster of 7 patients were identified with sinopulmonary IMIs (

Myxedema Coma as the Initial Presentation of Undiagnosed Hypothyroidism: A Rare but Reversible Emergency.

Myxedema coma is a rare, life-threatening endocrine emergency representing the extreme manifestation of untreated hypothyroidism. It usually presents with nonspecific symptoms such as confusion, hypothermia, and bradycardia, which can lead to delayed recognition, particularly in elderly patients with multiple comorbidities. We report the case of a 77-year-old man with hypertension, stage 4 chronic kidney disease, anemia of chronic disease, myeloma, and prostate cancer who presented with reduced consciousness following a period of increasing lethargy and confusion. On arrival, he was hypotensiv

Novel, thalidomide-like, non-cereblon binding drug tetrafluorobornylphthalimide mitigates inflammation and brain injury.

BACKGROUND: Quelling microglial-induced excessive neuroinflammation is a potential treatment strategy across neurological disorders, including traumatic brain injury (TBI), and can be achieved by thalidomide-like drugs albeit this approved drug class is compromised by potential teratogenicity. Tetrafluorobornylphthalimide (TFBP) and tetrafluoronorbornylphthalimide (TFNBP) were generated to retain the core phthalimide structure of thalidomide immunomodulatory imide drug (IMiD) class. However, the classical glutarimide ring was replaced by a bridged ring structure. TFBP/TFNBP were hence designed

Current trends of infectious complications following hematopoietic stem cell transplantation in a single center.

This study was to analyze the infectious complications after hematopoietic stem cell transplantation (HSCT) according to the recent changes of HSCT. Medical records of 379 adult patients who underwent HSCT consecutively at Catholic HSCT Center from January 2001 to December 2002 were reviewed retrospectively. Allogeneic HSCT accounted for 75.7% (287/379) and autologous HSCT for 24.3% (92/379). During pre-engraftment period, bacterial infection was predominant, and E. coli was still the most common organism. After engraftment, viral infection was predominant. The incidence of invasive fungal inf

Mitochondial Uncoupler, 2,4-Dinitrofon, уменьшает парализ спинальной коры и потерю ячеек сетчатки в экспериментальной аутоиммунной модели склероза.

Оптический неврит является воспалительным демиелинизирующим заболеванием зрительного нерва, которое часто встречается у пациентов с множественным склерозом (MS). Шестьдесят процентов пациентов имеют определенный уровень постоянной потери зрения из-за повреждения ячеек сетчатки после оптического неврата, при этом не известно, каким образом они могли бы предотвратить эту потерю. Проведенные ранее исследования показали, что MP201 - лекарство в виде 2,4 динозема (DNP), применяемое в экспериментальной модели мышью аутоиммунного энцефалита (EAE) MS-смягченного оптического невралита с сохранением зре

Astragaloside II, природный садонин, облегчает ремимиэлирование в демиэлинговых неврологических заболеваниях с помощью рецептора P75NTR, опосредованного осью сигнала β-катенина/Id2/MBP в клетках-прекурсорах олигодендроцитов.

КОЛИЧЕСТВО: Демиелинация является отличительной чертой неврологических расстройств, таких, как множественный склероз и оптика нейромиелита, что приводит к неврологическим расстройствам. Существующая терапия в первую очередь модифицирует иммунную реакцию, но не позволяет напрямую содействовать ремонту миелина. Расширение дифференциации олигодендроцитов и производства олигодендроцитов (ООП) имеет решающее значение для восстановления целостности миелина.ЦЕЛИ: В рамках этого исследования изучался терапевтический потенциал астрагалосида II (AS-II), биоактивного садонина с нейрозащитными и продиффер

Potential of Lycii Radicis Cortex as an Ameliorative Agent for Skeletal Muscle Atrophy.

Lycii Radicis Cortex (LRC) is a traditional medicine in East Asia with various beneficial effects, including antioxidant, anti-inflammatory, anti-tumor, anti-diabetic, and anti-depressant properties. However, its potential effects on skeletal muscle atrophy have not been studied. In this study, the protective effects of LRC extract (LRCE) on dexamethasone (DEX)-induced muscle atrophy were investigated in C2C12 myotubes and mice. We evaluated the effect of LRCE on improving muscle atrophy using a variety of methods, including immunofluorescence staining, quantitative polymerase chain reaction (

Impact of the COVID-19 pandemic on the diagnosis and treatment of onco-hematologic patients: a discussion paper.

We do not know the precise figure for solid organ tumors diagnosed each year in Spain and it is therefore difficult to calculate whether there has been a decrease in cancer diagnoses as a consequence of the pandemic. Some indirect data suggest that the pandemic has worsened the stage at which some non-hematological neoplasms are diagnosed. Despite the lack of robust evidence, oncology patients seem more likely to have a poor outcome when they contract COVID-19. The antibody response to infection in cancer patients will be fundamentally conditioned by the type of neoplasia present, the treatmen

Pontine Tuberculoma Mimicking an Astrocytic Tumor: A Case Report.

Tuberculomas located in the brainstem are rare entities. This article presents a case study detailing the diagnosis and treatment process of a patient with a pontine tuberculoma, as well as a literature review of tuberculomas located in the pons. A 39-year-old male patient showed progressive quadriparesis and deficits in VII, XI, and XII cranial nerves. MRI image initially suggested a pontine astrocytoma. A second biopsy revealed the presence of acid-fast bacilli. Following six months of anti-tuberculous treatment, the patient showed successful recovery.
