Evaluation of the systemic and mucosal immune response induced by COVID-19 and the BNT162b2 mRNA vaccine for SARS-CoV-2.

Background: The currently used SARS-CoV-2 mRNA vaccines have proven to induce a strong and protective immune response. However, functional relevance of vaccine-generated antibodies and their temporal progression are still poorly understood. Thus, the central aim of this study is to gain a better understanding of systemic and mucosal humoral immune response after mRNA vaccination with BNT162b2.

Cervical cancer in Ethiopia: a review of the literature.

Background: Cervical cancer is one of the most common malignancies affecting women worldwide with large geographic variations in prevalence and mortality rates. It is one of the leading causes of cancer-related deaths in Ethiopia, where vaccination and screening are less implemented. However, there is a scarcity of literature in the field.

Impact of Clonal Hematopoiesis in Patients With Cardiogenic Shock Complicating Acute Myocardial Infarction.

Background: Clonal hematopoiesis of indeterminate potential (CHIP) is common in elderly individuals and is associated with an increased risk of both hematologic malignancies and cardiovascular disease. The impact of CHIP on the outcomes for patients with cardiogenic shock (CS) complicating acute myocardial infarction (AMI) remains undetermined.

Objectives: The purpose of this study was to determine the prognostic impact of CHIP in CS after AMI.

Influence of diabetes on sacubitril/valsartan titration and clinical outcomes in patients hospitalized for heart failure.

Aims: Diabetes mellitus is associated with worse outcomes and lower attainment of disease-modifying therapies in patients with heart failure with reduced ejection fraction (HFrEF). This post hoc analysis of TRANSITION compared the patterns of tolerability and uptitration of sacubitril/valsartan in patients with HFrEF stabilized after hospital admission due to acute decompensated HF depending on the presence or absence of diabetes as a co-morbidity.

Methods: TRANSITION, a randomized, open-label study compared sacubitril/valsartan initiation pre-discharge vs.

Adjuvant nivolumab plus ipilimumab or nivolumab alone versus placebo in patients with resected stage IV melanoma with no evidence of disease (IMMUNED): final results of a randomised, double-blind, phase 2 trial.

Background: The IMMUNED trial previously showed significant improvements in recurrence-free survival for adjuvant nivolumab plus ipilimumab as well as for adjuvant nivolumab alone in patients with stage IV melanoma with no evidence of disease after resection or radiotherapy. Here, we report the final analysis, including overall survival data.

Methods: IMMUNED was an investigator-sponsored, double-blind, placebo-controlled, three-arm, phase 2 trial conducted in 20 academic medical centres in Germany.

Histopathological profile of cervical punch biopsies and risk factors associated with high-grade cervical precancerous lesions and cancer in northwest Ethiopia.

Introduction: Cervical cancer is an important public health problem in Ethiopia. However, the disease is not well characterized and studied in various parts of the country. This study was designed to describe the histopathological profile of cervical biopsies and to identify risk factors associated with high-grade cervical lesions and cancer (CIN2+C).

How Azanucleosides Affect Myeloid Cell Fate.

The azanucleosides decitabine and azacytidine are used widely in the treatment of myeloid neoplasia and increasingly in the context of combination therapies. Although they were long regarded as being largely interchangeable in their function as hypomethylating agents, the azanucleosides actually have different mechanisms of action; decitabine interferes primarily with the methylation of DNA and azacytidine with that of RNA. Here, we examine the role of DNA methylation in the lineage commitment of stem cells during normal hematopoiesis and consider how mutations in epigenetic regulators such as and can lead to clonal expansion and subsequent neoplastic progression.

Long-Term Efficacy and Safety of Luspatercept for Anemia Treatment in Patients With Lower-Risk Myelodysplastic Syndromes: The Phase II PACE-MDS Study.

JCO Luspatercept has high clinical activity in patients with transfusion-dependent lower-risk myelodysplastic syndromes (LR-MDS) and ring sideroblasts (RS) relapsed or refractory to erythropoietin. We report long-term luspatercept safety and efficacy in 108 patients with LR-MDS in the PACE-MDS study, including 44 non-RS and 34 non-transfusion-dependent or previously untreated patients. The primary end point was safety.

Spectrum of qualitative and quantitative imaging of pilomyxoid, intermediate pilomyxoid and pilocytic astrocytomas in relation to their genetic alterations.

Purpose: Pilomyxoid astrocytomas (PMA) are pediatric brain tumors predominantly located in the suprasellar region, third ventricle and posterior fossa, which are considered to be more clinically aggressive than pilocytic astrocytomas (PA). Another entity, intermediate pilomyxoid tumors (IPT), exists within the spectrum of pilocytic/pilomyxoid astrocytomas. The 2021 WHO CNS classification refrained from assigning grade 1 or 2 status to PMA, thereby reflecting the need to further elucidate their clinical and imaging characteristics.

Percutaneous transluminal angioplasty for symptomatic hepatic vein-type Budd-Chiari syndrome: feasibility and long-term outcomes.

For management of Budd-Chiari syndrome (BCS), a step-wise therapeutic approach starting with medical treatment, followed by endovascular recanalization, transjugular intrahepatic portosystemic shunt, and finally liver transplantation has been adopted. We retrospectively analyzed 51 patients with symptomatic short segment (≤ 30 mm) hepatic vein (HV)-type BCS who underwent percutaneous transluminal balloon angioplasty (PTBA) with/without stenting to determine the feasibility, clinical effectiveness, and long-term outcomes. The intervention was technically successful in 94.

Adrenalectomies in children and adolescents in Germany - a diagnose related groups based analysis from 2009-2017.

Background: Adrenalectomies are rare procedures especially in childhood. So far, no large cohort study on this topic has been published with data on to age distribution, operative procedures, hospital volume and operative outcome.

Methods: This is a retrospective analysis of anonymized nationwide hospital billing data (DRG data, 2009-2017).

Clinical Practice Guideline—Acute and Chronic Pancreatitis.

Background: Acute pancreatitis (AP) is among the commonest non-malignant admission diagnoses in gastroenterology. Its incidence in Germany lies between 13 and 43 per 100 000 inhabitants and is increasing. In 2017, 24 per 100 000 inhabitants were hospitalized for chronic pancreatitis.

A novel pilot animal model for bone augmentation using osseous shell technique for preclinical in vivo studies.

Objectives: Bone grafting is commonly used to reconstruct skeletal defects in the craniofacial region. Several bone augmentation models have been developed to evaluate bone formation using novel bone substitute materials. The aim of this study was to evaluate a surgical animal model for establishing a three-dimensional (3D) grafting environment in the animal's mandibular ramus for bone augmentation using the osseous shell technique, as in humans.

Pathogens and Shift of Resistance in Early Infections after Operative Fracture Fixation.

Surgical site infections (SSIs) remain a challenge for the healthcare system. During the last 30 years, the literature has shown an increase of gram-negative bacterial strains in multiple infectious sites and that cephalosporins have replaced penicillin as the gold standard in peri-operative antibiotic prophylaxis. This study aims to examine the recent bacterial spectrum in orthopedic early SSIs and to compare it with a historical cohort.

Nimodipine vs. Milrinone - Equal or Complementary Use? A Retrospective Analysis.

Background: Cerebral vasospasm (CVS) continues to account for high morbidity and mortality in patients surviving the initial aneurysmal subarachnoid hemorrhage (SAH). Nimodipine is the only drug known to reduce delayed cerebral ischemia (DCI), but it is believed not to affect large vessel CVS. Milrinone has emerged as a promising option.

Venetoclax synergizes with gilteritinib in FLT3 wild-type high-risk acute myeloid leukemia by suppressing MCL-1.

BCL-2 inhibition has been shown to be effective in acute myeloid leukemia (AML) in combination with hypomethylating agents or low-dose cytarabine. However, resistance and relapse represent major clinical challenges. Therefore, there is an unmet need to overcome resistance to current venetoclax-based strategies.

Hepatitis B virus reactivation associated with new classes of immunosuppressants and immunomodulators: A systematic review, meta-analysis, and expert opinion.

HBV reactivation (HBVr) can be prevented by nucleos(t)ide analogues (NAs). We conducted a systematic review and meta-analysis on the risk of HBVr associated with new classes of immunosuppressive and immunomodulatory therapies and developed guidance on NA prophylaxis. An expert panel reviewed the data and categorised the risk of HBVr associated with each class of drugs into low (<1%), intermediate (1-10%), and high (>10%).
