Trends of Antimicrobial Susceptibility of Neisseria gonorrhoeae Isolates Between 2012 and 2023: Results From an Open Italian Cohort.

Background: Neisseria gonorrhoeae (Ng) is a public health priority because of the rapid evolution of antimicrobial resistance, the emergence of antibiotic resistance, and the absence of a vaccine against Ng. The aim of this study was to investigate trends in the minimum inhibitory concentration and resistance (R) or reduced susceptibility (DS) of Ng cases to ceftriaxone (CRO), azithromycin (AZM), tetracycline (TET), benzylpenicillin (PenG), and ciprofloxacin (CIP) during a 10-year period.

Methods: We conducted a retrospective analysis on an open cohort of Ng cases diagnosed on rectal, urethral, and pharyngeal samples at San Raffaele Scientific Institute, between September 2012 and February 2023.

Levofloxacin prophylaxis vs no prophylaxis in patients with neutropenia within an endemic country for carbapenem-resistant GNB.

Fluoroquinolone prophylaxis's (FQ-P) usefulness in patients with neutropenia is controversial. In recent decades, Italian epidemiological data has shown worrisome rates of FQ resistance. A single-center cohort study on 136 autologous stem cell transplantations (ASCTs) and 223 allogeneic hematopoietic stem cell transplantations (allo-HSCTs) was performed from January 2018 to December 2020.

Identification of a novel mutation involved in colistin resistance in Klebsiella pneumoniae through Next-Generation Sequencing (NGS) based approaches.

The spread of multidrug-resistant (MDR) K. pneumoniae carbapenemase-producing bacteria (KPC) is one of the most serious threats to global public health. Due to the limited antibiotic options, colis- tin often represents a therapeutic choice.

Impact of surgical timing on survival in patients with infective endocarditis: a time-dependent analysis.

The purpose of this study was to evaluate the impact of surgical timing on survival in patients with left-sided infective endocarditis (IE). This was a retrospective study including 313 patients with left-sided IE between 2009 and 2017. Surgery was defined as urgent (US) or early (ES) if performed within 7 or 28 days, respectively.

Long-term outcome in multiple sclerosis patients treated with fingolimod.

Background And Purpose: Ongoing disease activity during treatment has been associated to worse disability outcomes in patients with Multiple Sclerosis (MS). The aim of this study was to assess the 5-year response to fingolimod (FTY) treatment in patients with relapsing-remitting (RRMS) in a real-life setting.

Methods: We included RRMS patients who received FTY for at least 6 months and had a follow-up ≥ 60 months.

Salvage heart transplantation for Mycoplasma hominis prosthetic valve endocarditis: A case report and review of the literature.

Heart transplantation (HT) has been rarely performed in patients with infective endocarditis (IE) and is considered a "last resort" procedure. Orthotropic HT with bicaval technique was performed in a man with culture-negative endocarditis. Mycoplasma hominis was later detected using 16S ribosomal DNA PCR from surgically removed valve tissue.

Results from Phase I Clinical Trial with Intraspinal Injection of Neural Stem Cells in Amyotrophic Lateral Sclerosis: A Long-Term Outcome.

The main objective of this phase I trial was to assess the feasibility and safety of microtransplanting human neural stem cell (hNSC) lines into the spinal cord of patients with amyotrophic lateral sclerosis (ALS). Eighteen patients with a definite diagnosis of ALS received microinjections of hNSCs into the gray matter tracts of the lumbar or cervical spinal cord. Patients were monitored before and after transplantation by clinical, psychological, neuroradiological, and neurophysiological assessment.

Palmitoylethanolamide in the Treatment of Failed Back Surgery Syndrome.

Introduction: This observational study was designed to evaluate the efficacy of ultramicronized palmitoylethanolamide (um-PEA) (Normast®) administration, as add-on therapy for chronic pain, in the management of pain-resistant patients affected by failed back surgery syndrome.

Methods: A total of 35 patients were treated with tapentadol (TPD) and pregabalin (PGB). One month after the start of standard treatment, um-PEA was added for the next two months.

What's growing on General Practitioner's stethoscope?

Background: Non-critical medical devices, as stethoscopes, have long been considered as vectors in microorganisms' transmission. Cleaning standards for non-critical medical equipment are often unclear. This study was designed to assess the attitude of General Practitioners (GPs) towards cleaning their stethoscope and the degree of microbiological contamination of doctor's instrument in outpatient setting.

LINAC-based radiosurgery for melanoma, sarcoma and renal cell carcinoma brain metastases.

Background: The aim of this study was to report response, overall survival (OS) and toxicity in patients with radioresistant brain metastases (BM) treated with stereotactic radiosurgery (SRS).

Methods: Patients with renal cell carcinoma, melanoma and sarcoma with one to four brain metastases received SRS without whole brain radiotherapy.

Results: Fifty patients with 77 BM were treated.

Human neural stem cell transplantation in ALS: initial results from a phase I trial.

Background: We report the initial results from a phase I clinical trial for ALS. We transplanted GMP-grade, fetal human neural stem cells from natural in utero death (hNSCs) into the anterior horns of the spinal cord to test for the safety of both cells and neurosurgical procedures in these patients. The trial was approved by the Istituto Superiore di Sanità and the competent Ethics Committees and was monitored by an external Safety Board.

Early molecular diagnosis of aspergillosis in a patient with acute myeloid leukaemia.

Diagnosis of invasive fungal infection remains challenging. Here we report a case of early diagnosis of invasive aspergillosis in a neutropenic patient affected by acute myeloid leukaemia, achieved through the detection of Aspergillus fumigatus species-specific ribonucleic acid sequences by a sensitive multiplex real-time polymerase chain reaction-based molecular assay. Thanks to the early diagnosis, targeted therapy was promptly established and the severe fungal infection controlled, allowing the patient to subsequently receive allogeneic hematopoietic stem cell transplantation from a haploidentical donor, her only curative option.

Cost-effectiveness of blood culture and a multiplex real-time PCR in hematological patients with suspected sepsis: an observational propensity score-matched study.

We evaluated the costs and clinical outcomes of episodes of suspected sepsis in hematological patients. A propensity score-matched study was planned, comparing a retrospective cohort managed with standard assays and a prospective cohort managed with the addition of a molecular assay. Diagnostic procedures and therapy were considered as costs variables.

Neural stem cells and glioblastoma.

Glioblastoma multiforme represents one of the most common brain cancers with a rather heterogeneous cellular composition, as indicated by the term "multiforme". Recent reports have described the isolation and identification of cancer neural stem cells from human adult glioblastoma multiforme, which possess the capacity to establish, sustain, and expand these tumours, even under the challenging settings posed by serial transplantation experiments. Our study focused on the distribution of neural cancer stem cells inside the tumour.
