White blood cells, TNF-α, and interleukin-6 in subjects with infantile colic treated with Lacticaseibacillus rhamnosus GG (ATCC 53103): a randomised prospective study.

Recent metanalysis reported that certain probiotic strains, such as Limosilactobacillus reuteri and Lacticaseibacillus rhamnosus (LGG), seem effective for treatment of infantile colic of exclusively breastfed infants; some reports have also linked probiotics to have an immunological effect, however further investigation are needed to fully understand the exact mechanism. The objective of this study was to assay white blood cells, tumour necrosis factor (TNF)-α and interleukin (IL)-6 values in peripheral blood in subjects treated in a randomised, double-blind, placebo-controlled trial for infantile colic with LGG. Fifty-eight infants were enrolled and followed for a study period of 28 days.

Thromboprophylaxis/anticoagulation treatment is often required in hospitalized COVID-19 patients. We aimed to estimate the prevalence of major bleeding events in hospitalized COVID-19 patients. This was a retrospective observational study including all COVID-19 hospitalized patients ≥18 years of age at one reference center in northern Italy.

Phage Therapy for Cardiac Implantable Electronic Devices and Vascular Grafts: A Targeted Literature Review.

Infections of cardiac implantable electronic devices (CIEDs) and vascular grafts are some of the most dreaded complications of these otherwise life-saving devices. Many of these infections are not responsive to conventional treatment, such as systemic antibiotics and surgical irrigation and debridement. Therefore, innovative strategies to prevent and manage these conditions are warranted.

Traditional Cultures versus Next Generation Sequencing for Suspected Orthopedic Infection: Experience Gained from a Reference Centre.

(Background) The diagnosis and the antimicrobial treatment of orthopedic infection are challenging, especially in cases with culture-negative results. New molecular methods, such as next-generation sequencing (NGS), promise to overcome some limitations of the standard culture, such as the detection of difficult-to-grow bacteria. However, data are scarce regarding the impact of molecular techniques in real-life scenarios.

Trimethoprim-sulfamethoxazole significantly reduces the risk of nocardiosis in solid organ transplant recipients: systematic review and individual patient data meta-analysis.

Background: Whether trimethoprim-sulfamethoxazole (TMP-SMX) prophylaxis prevents nocardiosis in solid organ transplant (SOT) recipients is controversial.

Objectives: To assess the effect of TMP-SMX in the prevention of nocardiosis after SOT, its dose-response relationship, its effect on preventing disseminated nocardiosis, and the risk of TMP-SMX resistance in case of breakthrough infection.

Methods: A systematic review and individual patient data meta-analysis.

Rifampin Based Therapy for Patients With Staphylococcus aureus Native Vertebral Osteomyelitis: A Systematic Review and Meta-analysis.

Background: Native vertebral osteomyelitis (NVO) caused by Staphylococcus aureus is associated with high risk of treatment failure and increased morbidity. The role of rifampin-based therapy for the treatment of this condition is controversial. The goal of this systematic review and meta-analysis is to explore the efficacy and safety of rifampin-based therapy for the treatment of S.

Plants and Mushrooms as Possible New Sources of HS Releasing Sulfur Compounds.

Hydrogen sulfide (HS), known for many decades exclusively for its toxicity and the smell of rotten eggs, has been re-discovered for its pleiotropic effects at the cardiovascular and non-cardiovascular level. Therefore, great attention is being paid to the discovery of molecules able to release HS in a smart manner, i.e.

in spine tissue: characteristics and outcomes of non-hardware-associated vertebral osteomyelitis.

isolation from spine tissue can be challenging because the organism can represent a contaminant. There is a paucity of data regarding the role of in non-hardware-associated vertebral osteomyelitis (VO). Herein we evaluate the clinical and microbiological characteristics, treatment, and outcome of patients with VO.

Functional humoral and cellular response of monovalent COVID-19-vaccines against Omicron BA.2 variant of SARS-CoV-2 in patients with chronic lymphocytic leukemia.

We designed a prospective study to evaluate the humoral (using a surrogate virus neutralization test) and cellular (using an IFN-γ ELISpot) immune response among patients with chronic lymphocytic leukemia (CLL) against Wuhan-Hu-1 and Omicron BA.2 strains of SARS-CoV-2, after mRNA-based vaccination. The proportion of patients with a functional humoral response was higher among untreated CLL patients compared to treated CLL patients against both Wuhan-Hu-1 and Omicron BA.

The use of MRI, PET/CT, and nuclear scintigraphy in the imaging of pyogenic native vertebral osteomyelitis: a systematic review and meta-analysis.

Background Context: Native vertebral osteomyelitis (NVO) is a severe infection with an increasing incidence globally. Although there is no widely agreed upon reference standard for diagnosis of the disease, imaging plays a crucial role. Magnetic resonance imaging (MRI) is currently the imaging modality of choice.

Early switch to oral antibiotic therapy for the treatment of patients with bacterial native vertebral osteomyelitis: a quaternary center experience, systematic review, and meta-analysis.

Recent data suggest that oral therapy can be effective for bone infections. We aim to assess the efficacy of an early switch to oral therapy (  weeks) compared to a non-early switch in bacterial native vertebral osteomyelitis. We conducted a cohort study at Mayo Clinic, Rochester (MN), between 2019-2021 combined with a systematic review, which queried multiple databases.

Natural Cryoprotective and Cytoprotective Agents in Cryopreservation: A Focus on Melatonin.

Cryoprotective and cytoprotective agents (Cytoprotective Agents) are fundamental components of the cryopreservation process. This review presents the essentials of the cryopreservation process by examining its drawbacks and the role of cytoprotective agents in protecting cell physiology. Natural cryoprotective and cytoprotective agents, such as antifreeze proteins, sugars and natural deep eutectic systems, have been compared with synthetic ones, addressing their mechanisms of action and efficacy of protection.

Application of Ultrasonography in Neurogenic Dysphagia: A Systematic Review.

Swallowing disorders are common in neurological diseases, with dysphagia representing one of the most prevalent complications that may cause poor quality of life, reduce independence, and increase mortality. Rapid identification of dysphagia is necessary to reduce the risk of penetration and aspiration, and to early start rehabilitation protocols. Among the methods that can be used to evaluate dysphagia and its components, ultrasound imaging has been suggested to support the evaluation of dysphagia by providing measures of both static and dynamic anatomical components.

Mortality among Italians and immigrants with COVID-19 hospitalised in Milan, Italy: data from the Luigi Sacco Hospital registry.

Background: To compare differences in the probability of COVID-19-related death between native Italians and immigrants hospitalised with COVID-19.

Methods: This retrospective study of prospectively collected data was conducted at the ASST Fatebenefratelli-Sacco Hospital in Milan, Italy, between 21 February and 31 November 2020. Uni- and multivariable Cox proportional hazard models were used to assess the impact of the patients' origin on the probability of COVID-19-related death.

A novel ophthalmic latanoprost 0.005% nanoemulsion: a cytotoxicity study.

Background: Benzalkonium chloride (BAK), the most commonly used preservative in anti-glaucoma eye drops, inflicts damage to the ocular surface. A novel anti-glaucoma formulation that avoids the use of BAK has been developed. The aim of this study was to evaluate the cytotoxicity of this formulation and to compare it with an ophthalmic solution containing BAK.
