Transphyseal elbow fracture in newborn: review of literature.

Transphyseal elbow fracture is a rare entity in newborns, and in the last century, only case reports or small case series have been published; however, precise epidemiological data lack. Such fractures occur more often in emergency Caesarian section or vaginal delivery. The differential diagnosis with elbow dislocation can be challenging.

Novel missense mutations in PNPLA2 causing late onset and clinical heterogeneity of neutral lipid storage disease with myopathy in three siblings.

Neutral lipid storage disease with myopathy (NLSD-M) is a rare autosomal recessive disorder characterised by an abnormal accumulation of triacylglycerol into cytoplasmic lipid droplets (LDs). NLSD-M patients are mainly affected by progressive myopathy, cardiomyopathy and hepatomegaly. Mutations in the PNPLA2 gene cause variable phenotypes of NLSD-M.

Nanosized TiO2 is internalized by dorsal root ganglion cells and causes damage via apoptosis.

Unlabelled: Titanium dioxide (TiO2) is widely used as ingredient in several products in the nanoform. TiO2-nanoparticles (NPs) are also currently studied for different medical applications. A large debate exists on possible adverse health effects related to their exposure.

Chemical characterization and ecotoxicity of three soil foaming agents used in mechanized tunneling.

The construction of tunnels and rocks with mechanized drills produces several tons of rocky debris that are today recycled as construction material or as soil replacement for covering rocky areas. The lack of accurate information about the environmental impact of these excavated rocks and foaming agents added during the excavation process has aroused increasing concern for ecosystems and human health. The present study proposes an integrated approach to the assessment of the potential environmental impact of three foaming agents containing different anionic surfactants and other polymers currently on the market and used in tunnel boring machines.

The Potential for Plant Derivatives against Acrylamide Neurotoxicity.

Certain industrial chemicals and food contaminants have been demonstrated to possess neurotoxic activity and have been suspected to cause brain-related disorders in humans. Acrylamide (ACR), a confirmed neurotoxicant, can be found in trace amount in commonly consumed human aliments as a result of food processing or cooking. This discovery aroused a great concern in the public, and increasing efforts are continuously geared towards the resolution of this serious threat.

Objective: Hospitals are expected to serve the medical needs of casualties in the face of a disaster or other crisis, including man-made conflicts. The aim of this study was to evaluate the impact of the 2011 Yemeni revolution on hospital disaster preparedness in the capital city of Sana'a.

Methods: The study was conducted in September 2011 and 2013.

Genetic determinants of chronic oxaliplatin-induced peripheral neurotoxicity: a genome-wide study replication and meta-analysis.

We aimed at validating the role of genetic variants identified by a recent genome-wide association study (GWAS) as determinants of chronic oxaliplatin-induced peripheral neurotoxicity (OXAIPN). Eight polymorphisms (rs10486003, rs2338, rs843748, rs797519, rs4936453, rs12023000, rs17140129, and rs6924717) were genotyped in a total of 150 colorectal cancer patients of Caucasian origin receiving oxaliplatin-based chemotherapy. The severity grade of chronic OXAIPN was assessed by NCI-CTC criteria and the clinical version of the Total Neuropathy Score(©) (TNSc(©) ).

The Kings Score refines prognostic prediction in hepatocellular carcinoma: a novel application.

Background & Aims: There are a number of prognostic scores in hepatocellular carcinoma (HCC), none of which is optimal in predicting overall survival (OS) in the individual patient, particularly in intermediate stage disease, where patients are not surgically treatable but may qualify for a wide range of palliative interventions. We evaluated the prognostic role of a biochemical algorithm, the Kings Score (KS), in the palliative setting of care.

Methods: We used the algorithm [age x AST x INR]/platelet count to derive the KS.

Multiple withdrawals from single-use vials: a study on sterility.

Background: Reutilization of single-use vials containing medical drugs is still under discussion. This practice has been adopted as a standard to avoid drug wastage, particularly in developing countries and in the aftermath of disasters. Some studies have assessed sterility of medications stored in single-use vials after utilization as multiple doses; however, most of these were limited to one single drug, included a low number of samples and did not consider an intermediate transfer step from the vial to a disposable syringe.

PM10 in a background urban site: chemical characteristics and biological effects.

PM10 was sampled in a background urban site in Torino, a northern Italian city. PM10 extracts were tested with THP-1 and A-549 cells to evaluate their effects on cell proliferation, LDH activity, TNFα, IL8 and CYP1A1 expression, and genotoxic damage induction (Comet assay). Through Principal Component Analysis (PCA), it was observed that (1) the aqueous extracts induced the inhibition of cell proliferation in the warm season that clustered together to total ions, (2) organic extracts determined a winter cell viability reduction and (3) there was a genotoxic effect associated with PAH and metal concentrations.

Interaction between visual and motor cortex: a transcranial magnetic stimulation study.

The major link between the visual and motor systems is via the dorsal stream pathways from visual to parietal and frontal areas of the cortex. Although the pathway appears to be indirect, there is evidence that visual input can reach the motor cortex at relatively short latency. To shed some light on its neural basis, we studied the visuomotor interaction using paired transcranial magnetic stimulation (TMS).

Susceptibility of Vibrio aestuarianus 01/032 to the antibacterial activity of Mytilus haemolymph: identification of a serum opsonin involved in mannose-sensitive interactions.

The interactions of Vibrio aestuarianus 01/032 with haemolymph of the bivalves Mytilus galloprovincialis and Crassostrea gigas were investigated to understand if haemolymph components (haemocytes and soluble factors) could be involved in the higher resistance to microbial infection shown by mussels in comparison with oysters. Although 01/032 bacteria adhered to haemocytes of both bivalves, they were sensitive to the bactericidal activity of whole haemolymph from mussel, but not from oyster; in addition, adhesion to mussel (but not oyster) haemocytes was affected by D-mannose. Mussel serum opsonins directed towards D-mannose-binding bacterial ligands were purified by affinity chromatography and were shown to mediate 01/032 interactions with M.

Combining Dedicated Online Training and Apprenticeships in the Field to Assist in Professionalization of Humanitarian Aid Workers: a 2-year Pilot Project for Anesthesia and Intensive Care Residents Working in Resource Constrained and Low-income Countries.

Introduction: As a result of the gaps in humanitarian response highlighted by several reports, the international community called for an increased professionalization of humanitarian aid workers. This paper describes a pilot project by an Italian university and a non-profit, non-governmental organization to implement a medical apprenticeship in low-income countries during Anesthesia and Intensive Care Medicine residencies.

Methods: Before deployment, participants were required to complete a dedicated online training course about safety and security in the field, principles of anesthesia at the district hospital level, emergency and essential surgical care, essentials of medical treatment in resource-constrained environments and psychological support in emergencies.

Analysis of genes, pathways and networks involved in disease severity and age at onset in primary-progressive multiple sclerosis.

Background: The role of genetic factors in influencing the clinical expression of multiple sclerosis (MS) is unclear.

Objective: The objective of this paper is to identify genes, pathways and networks implicated in age at onset (AAO) and severity, measured using the Multiple Sclerosis Severity Score (MSSS), of primary-progressive MS (PPMS).

Methods: We conducted a genome-wide association study (GWAS) of 470 PPMS patients of Italian origin:.

One-year treatment with liraglutide improved renal function in patients with type 2 diabetes: a pilot prospective study.

Unlike GLP-1, liraglutide is not cleared by the glomerulus and its pharmacokinetic is not altered in patients with mild renal impairment. The aim of our study was to analyze the effects of liraglutide on renal function in patients with type 2 diabetes. A twelve-month longitudinal prospective post-marketing study was performed.

Validation of the hepatoma arterial embolization prognostic score in European and Asian populations and proposed modification.

Background & Aims: Transarterial chemoembolization (TACE) is used to treat hepatocellular carcinoma (HCC), but it is a challenge to predict patient survival. The hepatic arterial embolization prognostic (HAP) score has been shown to predict which patients will have shorter survival times and should not undergo TACE. We aimed to validate this scoring system in a prospective study of patients in Europe and Asia.

Leptin level lowers in proportion to the amount of aerobic work after four weeks of training in obesity.

Leptin values are higher in obesity. Physical exercise reduces fat mass (FM) and decreases leptin levels. Intensity of physical training seems to play a role in reducing circulating leptin.

Growth hormone deficiency in treated acromegaly.

Growth hormone deficiency (GHD) of the adult is characterized by reduced quality of life (QoL) and physical fitness, skeletal fragility, and increased weight and cardiovascular risk. Hypopituitarism may develop in patients after definitive treatment of acromegaly, but an exact prevalence of GHD in this population is still uncertain owing to limited awareness and the scarce and conflicting data available on this topic. Because acromegaly and GHD may yield adverse consequences on similar target systems, the final outcomes of some complications of acromegaly may be further affected by the occurrence of GHD.

Chronic exposure to TGFβ1 regulates myeloid cell inflammatory response in an IRF7-dependent manner.

Tissue microenvironment influences the function of resident and infiltrating myeloid-derived cells. In the central nervous system (CNS), resident microglia and freshly recruited infiltrating monocyte-derived macrophages (mo-MΦ) display distinct activities under pathological conditions, yet little is known about the microenvironment-derived molecular mechanism that regulates these differences. Here, we demonstrate that long exposure to transforming growth factor-β1 (TGFβ1) impaired the ability of myeloid cells to acquire a resolving anti-inflammatory phenotype.

An optimized table-top small-angle X-ray scattering set-up for the nanoscale structural analysis of soft matter.

The paper shows how a table top superbright microfocus laboratory X-ray source and an innovative restoring-data algorithm, used in combination, allow to analyze the super molecular structure of soft matter by means of Small Angle X-ray Scattering ex-situ experiments. The proposed theoretical approach is aimed to restore diffraction features from SAXS profiles collected from low scattering biomaterials or soft tissues, and therefore to deal with extremely noisy diffraction SAXS profiles/maps. As biological test cases we inspected: i) residues of exosomes' drops from healthy epithelial colon cell line and colorectal cancer cells; ii) collagen/human elastin artificial scaffolds developed for vascular tissue engineering applications; iii) apoferritin protein in solution.

Effects of PAHs and dioxins on the earthworm Eisenia andrei: a multivariate approach for biomarker interpretation.

In this study, a battery of biomarkers was utilised to evaluate the stress syndrome induced in the earthworm Eisenia andrei by exposure to environmentally realistic concentrations of benzo[a]pyrene (B[a]P) and 2,3,7,8-tetrachlorodibenzo-para-dioxin (TCDD) in OECD soil. The set of tests was then employed to assess the toxicity of field soils contaminated with organic xenobiotic compounds (such as PAHs, dioxins and PCBs). The results highlighted an impairment of immune and metabolic functions and genotoxic damage in worms exposed also to lower bioavailable concentrations of toxic chemicals.

Transcranial Direct Current Stimulation Effects on Single and Paired Flash Visual Evoked Potentials.

Transcranial direct current stimulation (tDCS) applied over the occipital cortex has a controversial effect on the visual cortex excitability. Paired flash visual evoked potentials (paired F-VEPs) offer a unique method to express neural inhibition within the visual system. However, no studies have explored the effects of tDCS on F-VEPs in humans.

Role of beta-blockers in patients with COPD: current perspective.

Chronic obstructive pulmonary disease (COPD) is characterized by poorly reversible airflow limitation, with an abnormal pulmonary and systemic inflammatory response to tobacco smoking. Systemic inflammation promotes atherosclerosis, to treat the complications of which beta-blockers are paramount. In the COPD setting, however, the use of beta-blockers has been limited by fears that they could adversely affect lung function.
