Covid-19 diagnosis and mortality in patients with non-ST-elevation myocardial infarction admitted in Italy during the national outbreak.

Introduction: We sought to assess the clinical impact of Covid-19 infection on mortality in patients with Non-ST elevation myocardial infarction (NSTEMI) admitted during the national outbreak in Italy.

Methods: We analysed a nationwide, comprehensive, and universal administrative database of consecutive NSTEMI patients admitted during lockdown for Covid-19 infection (March,11st - May 3rd, 2020) and the equivalent periods of the previous 5 years in Italy. The observed rate of 30-day and 6-month all-cause mortality of NSTEMI patients with and without Covid-19 infection during the lockdown was compared with the expected rate of death according to the trend of the previous 5 years.

Definition of Optimal Optical Coherence Tomography-Based Stent Expansion Criteria: In-Stent Minimum Lumen Area Versus Residual Stent Underexpansion.

Background: The mismatch between in-stent minimum lumen area (sMLA) and reference vessel lumen area, defined as stent underexpansion (SU), could be an important determinant of stent failure. We tested the clinical predictive value of absolute sMLA in comparison to relative SU in the context of the CLI-OPCI (Centro Per La Lotta Contro L'Infarto-Optimisation of Percutaneous Coronary Intervention) project registry.

Methods: We retrospectively analyzed end procedural optical coherence tomography findings in 1211 patients (1422 lesions) undergoing percutaneous coronary intervention, assessing the prevalence and magnitude of residual SU and exploring correlation with outcome in comparison with sMLA.

In vivo assessment of associations between photoreceptors structure and macular perfusion in type 1 diabetes.

Design: Observational cross-sectional study.

Methods: Forty eyes of consecutive patients with DM1 (12 NoDR and 28 NPDR) and 10 healthy age-matched control subjects were included.

Hesitancy toward Childhood Vaccinations: Preliminary Results from an Albanian Nursing Staff's Investigation.

Healthcare professionals are important models for their patients since their individual knowledge and attitudes toward vaccination can influence the patient's willingness to adhere to vaccination campaigns. After developing a structured questionnaire, it was administered to a sample of nursing staff working in public vaccination centers in Albania (December 2020-January 2021), in order to conduct a preliminary investigation aimed at describing knowledge, attitudes, beliefs, and hesitancy toward childhood vaccinations. Among the sample of nurses involved in the administration of vaccines (n.

Sub-retinal pigment epithelium tubules in non-neovascular age-related macular degeneration.

To describe a novel optical coherence tomography (OCT) signature resembling sub-retinal pigment epithelium (RPE) tubules (SRT) in non-neovascular age-related macular degeneration (AMD). Patients suffering from non-neovascular AMD with complete medical records and multimodal imaging were retrospectively revised in three different tertiary care centers. Multimodal imaging included color fundus photograph, spectral-domain OCT (Spectralis, Heidelberg Engineering, Germany), fundus autofluorescence, OCT angiography (RTVue XR Avanti, Optovue, Inc.

Synthesis of Novel Hyaluronic Acid Sulfonated Hydrogels Using Safe Reactants: A Chemical and Biological Characterization.

Here, we present a one-pot procedure for the preparation of hyaluronic acid (HA) sulfonated hydrogels in aqueous alkaline medium. The HA hydrogels were crosslinked using 1,4-butanedioldiglycidyl ether (BDDE) alone, or together with N-bis(2-hydroxyethyl)-2-aminoethanesulfonic acid (Bes), as a safe sulfonating agent. Conditions for the simultaneous reaction of HA with BDDE and Bes were optimized and the resulting hydrogels were characterized under different reaction times (24, 72, and 96 h).

Towards a better understanding of non-exudative choroidal and macular neovascularization.

Non-exudative macular and choroidal neovascularization (MNV and CNV) usually refers to the entity of treatment-naïve type 1 neovascularization in the absence of associated signs of exudation. Histopathological studies, dating back in the early 70s, identified the presence of non-exudative MNV, but the first clinical report of this finding was in the late 90s using indocyanine green angiography in eyes with age-related macular degeneration (AMD). With more advanced retinal imaging, there has been an ever increasing appreciation of non-exudative MNV associated with AMD and CNV with other macular disorders.

Impact of , and Genetic Polymorphisms in the Response to TNF-i Treatment in Patients with Psoriatic Arthritis.

Psoriatic arthritis (PsA) is a chronic inflammatory rheumatic disease. The introduction of therapy with biological drugs is promising, even if the efficacy is very variable. Since the response to drugs is a complex trait, identifying genetic factors associated to treatment response could help define new biomarkers for a more effective and personalized therapy.

An Polycythemia Vera Evolve from Acute Myeloid Leukemia? Report of a Case Showing a Simultaneous Minor V617F Mutated Clone.

The evolution of myeloproliferative neoplasms (MPN) to acute myeloid leukemia (AML) occurs in 2-10% of patients, depending on the MPN subtype, treatment, and follow-up length. The reverse-path from AML to MPN has been rarely reported. We herein present a 75 years old woman with AML, in whom a -V617F positive polycythemia vera (PV) emerged during follow-up, 19 months from the end of consolidation treatment.

Medullary Thyroid Cancer with Ectopic Cushing's Syndrome: A Case Report and Systematic Review of Detailed Cases from the Literature.

Medullary thyroid cancer (MTC) is a neuroendocrine tumor arising from parafollicular C-cells of the thyroid gland that, in rare cases, can cause a paraneoplastic ectopic Cushing's syndrome (ECS). The development of Cushing's syndrome (CS) in MTC patients is generally associated with advanced disease and poor prognosis. We described a case of severe CS due to MTC in a young male.

Vitamin C Deficiency in Patients With Acute Myeloid Leukemia.

Vitamin C has been shown to play a significant role in suppressing progression of leukemia through epigenetic mechanisms. We aimed to study the role of vitamin C in acute myeloid leukemia (AML) biology and clinical course. To this purpose, the plasma levels of vitamin C at diagnosis in 62 patients with AML (including 5 cases with acute promyelocytic leukemia, APL),7 with myelodysplastic syndrome (MDS), and in 15 healthy donors (HDs) were studied.

Prevalence of CAH-X Syndrome in Italian Patients with Congenital Adrenal Hyperplasia (CAH) Due to 21-Hydroxylase Deficiency.

21-hydroxylase deficiency (21OHD), the most common form of congenital adrenal hyperplasia (CAH), is associated with pathogenic variants in gene. The clinical form of the disease ranges from classic or severe to non-classic (NC) or mild late onset. The gene is located on the long arm of chromosome 6, within the RCCX region, one of the most complex loci in the human genome.

Biochemical Discrimination of the Down Syndrome-Related Metabolic and Oxidative/Nitrosative Stress Alterations from the Physiologic Age-Related Changes through the Targeted Metabolomic Analysis of Serum.

Down Syndrome (DS) is a neurodevelopmental disorder that is characterized by an accelerated aging process, frequently associated with the development of Alzheimer's disease (AD). Previous studies evidenced that DS patients have various metabolic anomalies, easily measurable in their serum samples, although values that were found in DS patients were compared with those of age-matched non-DS patients, thus hampering to discriminate the physiologic age-related changes of serum metabolites from those that are truly caused by the pathologic processes associated with DS. In the present study we performed a targeted metabolomic evaluation of serum samples from DS patients without dementia of two age classes (Younger DS Patients, YDSP, aging 20-40 years; Aged DS Patients, ADSP, aging 41-60 years), comparing the results with those that were obtained in two age classes of non-DS patients (Younger non-DS Patients, YnonDSP, aging 30-60 years; Aged-nonDS Patients, AnonDSP, aging 75-90 years).

A multilocus genetic study evidences the association of autoimmune-related genes with Psoriatic Arthritis in Italian patients.

Psoriatic Arthritis (PsA) is an immune-mediated rheumatic disease caused by the interaction between environmental factors and genetic predisposition. Many of the risk loci associated with PsA susceptibility are shared with other autoimmune diseases, suggesting an involvement of the same pathways in these diseases. We investigated the association between nine selected polymorphisms and PsA susceptibility and their possible role in the modulation of the disease activity.

De Novo and Therapy-Related Myelodysplastic Syndromes: Analogies and Differences.

The aim of our review has been to give an appropriate idea of analogies and differences between primitive MDS (p-MDS) and t-MDS throughout an accurate reviewing of English peer-reviewed literature focusing on clinical, cytogenetic, epigenetic, and somatic mutation features of these two groups of diseases. Therapy-related MDS (t-MDS) are classified by WHO together with therapy-related acute myeloid leukemia (t-AML) in the same group, named therapy-related myeloid neoplasm. However, in clinical practice, the diagnosis of t-MDS is made with the same criteria as for primitive MDS (p-MDS), and the only difference is a previous non-myeloid neoplasm.

The Venetoclax/Azacitidine Combination Targets the Disease Clone in Acute Myeloid Leukemia, Being Effective and Safe in a Patient with COVID-19.

The addition of Venetoclax (VEN) to Hypomethylating agents (HMAs) significantly improves the probability of complete remission and prolongs survival in patients with Acute Myeloid Leukemia (AML) when compared to HMA alone. However, the mutated clone composition may impact the probability of response and its duration. Here, we describe the molecular profile of a patient with AML rapidly evolved from a previous therapy-related-Chronic MyeloMonocytic Leukemia, who achieved safely complete remission after treatment with the VEN/Azacitidine combination, even in the presence of SARS-COVID-2 infection.

Atypical Rearrangements in APL-Like Acute Myeloid Leukemias: Molecular Characterization and Prognosis.

Acute promyelocytic leukemia (APL) accounts for 10-15% of newly diagnosed acute myeloid leukemias (AML) and is typically caused by the fusion of promyelocytic leukemia with retinoic acid receptor α () gene. The prognosis is excellent, thanks to the all-trans retinoic acid (ATRA) and arsenic trioxide (ATO) combination therapy. A small percentage of APLs (around 2%) is caused by atypical transcripts, most of which involve or other members of retinoic acid receptors ( or ).

The biochemical diagnosis of acromegaly: revising the role of measurement of IGF-I and GH after glucose load in 5 questions.

Introduction: Acromegaly is a rare disorder characterized by the excessive secretion of growth hormone (GH), mostly caused by pituitary adenomas. While in full-blown cases the diagnosis is easy to establish, milder cases are more challenging. Additionally, establishing whether full cure after surgery is reached may be difficult.

The role of gender in a large international OCD sample: A Report from the International College of Obsessive-Compulsive Spectrum Disorders (ICOCS) Network.

Introduction: Obsessive-compulsive disorder (OCD) is characterized by a range of phenotypic expressions. Gender may be a relevant factor in mediating the disorder's heterogeneity. The aim of the present report was to explore a large multisite clinical sample of OCD patients, hypothesizing existing demographic, geographical and clinical differences between male and female patients with OCD.
