OBJECTIVE: The authors present a multicenter retrospective series of different benign rib lesions in children operated on using thoracoscopy. MATERIALS AND METHODS: Between 2005 and 2015, 17 rib resections were performed thoracoscopically, in four French departments of pediatric surgery. Of these 17 cases, 13 exostoses, 2 endochondromas, 1 synostosis, and 1 Cyriax's syndrome were noted. Inclusion criteria were benign tumors or rib anomalies such as synostosis, in children younger than the age of 18 years, and thoracoscopy...

The Cytotoxic Necrotizing Factor 1 (CNF1) is a bacterial toxin secreted by certain Escherichia coli strains causing severe pathologies, making it a protein of pivotal interest in toxicology. In parallel, the CNF1 capability to influence important neuronal processes, like neuronal arborisation, astrocytic support, and efficient ATP production, has been efficiently used in the treatment of neurological diseases, making it a promising candidate for therapy. Nonetheless, there are still some unsolved issues about the CNF1 mechanism of action and structuration probably caused by the difficulty to achieve sufficient amounts of the full-length protein for further studies...

A disease risk index (DRI) has been defined for stratifying heterogeneous cohorts of patients undergoing allogeneic haematopoietic stem cell transplantation (HSCT). This index defines 4 distinct groups with different outcomes, dividing patients by disease type and status and considering cytogenetics for acute myeloid leukaemia and myelodysplastic syndromes (MDS). Recently, the DRI has been refined to include rare diseases and improve MDS stratification by blast percentage and response to prior therapy. Previous reports on DRI include only a small number of UCBT recipients...

BACKGROUND AND PURPOSE: Elevated blood pressure (BP) is associated with greater severity of intracranial atherosclerotic stenosis (ICAS) and increased risk of ischemic stroke. Because little is known about the relationship of maintained BP level with progression of symptomatic ICAS (sICAS), we evaluated the independent association of maintained systolic BP (SBP) with risk of sICAS progression. METHODS: We analyzed the Trial of cilOstazol in Symptomatic intracranial Stenosis 2, which evaluated 402 stroke patients with sICAS (mean age, 64...

While much emphasis, and some controversy, centers on recommendations for sodium intake, there has been considerably less interest in recommendations for dietary potassium intake, in both the general population and patients with medical conditions, particularly acute and chronic kidney disease. Physiology literature and cohort studies have noted that the relative balance in sodium and potassium intakes is an important determinant of many of the sodium-related outcomes. A noteworthy characteristic of potassium in clinical medicine is the extreme concern shared by many practitioners when confronted by a patient with hyperkalemia...

Recently, mixed duplex/quadruplex oligonucleotides have attracted great interest for use as biomedical aptamers. In the case of anti-thrombin aptamers, the addition of duplex-forming sequences to a G-quadruplex module identical or very similar to the best-known G-quadruplex of the Thrombin Binding Aptamer (HD1) results in new or improved biological properties, such as higher activity or different recognition properties with respect to HD1. Remarkably, this bimodular fold was hypothesized, based on its sequence, for the only anti-thrombin aptamer in advanced clinical trial, NU172...

Background: Gram-negative bacteremia (GNB) is a major cause of morbidity and mortality in Hematopoietic Stem Cell Transplant (HSCT) and updated epidemiological investigation is advisable. Methods: We prospectively evaluated the epidemiology of pre-engraftment GNB in 1,118 allogeneic HSCT (allo-HSCT) and 1,625 autologous HSCT (auto-HSCT) among 54 transplant centers during 2014 (SIGNB-GITMO-AMCLI study). Using logistic regression methods we identified risk factors for GNB and evaluated the impact of GNB on the 4-month overall-survival after transplant...

OBJECTIVES: Recently, a debate article by Parker et al. was published regarding the biological type of depression, melancholia, in which they discussed its clinical presentation, particularly that involving psychomotor disturbances. However, there is one feature of melancholia that is frequently forgotten, to which this article aims to devote special attention: ruminative thoughts of guilt. METHODS: A critical review of the literature. RESULTS: The symptom of ruminative thoughts of guilt has been described historically in melancholia, and some recent data, such as neurobiological abnormalities and poor prognosis, support it as an important feature of depression...

Tumor-associated myeloid cells (TAMCs), mainly represented by tumor-associated macrophages (TAMs) and myeloid-derived suppressor cells (MDSCs), can promote tumor growth directly, by favouring tumor cell proliferation and survival, and indirectly, by creating an immunosuppressive microenvironment. Myeloid cells are characterized by an extreme phenotypical and functional plasticity. Immunometabolism is now emerging as a crucial aspect of TAMCs skewing towards pro-tumoral activities. The metabolic re-education of myeloid cells is a new strategy to boost their anti-tumor effector functions...

Patients with acute graft versus host disease (GvHD) grade I, were randomized, to an observation arm (n=85) or to a treatment arm (n=86), consisting of 6-methylprednisolone 1 mg/kg/day , after stratification for age and donor type. The primary end point was development of grade II-IV GvHD. The cumulative incidence of GvHD grade II-IV, was 50% in the observation and 33% in the treatment arm (p=0.005). However, grade III-IV GvHD was comparable (13% vs 10% respectively; p=0.6), and this was true for sibling and alternative donor transplants...

Pleural effusion (PE) represents the leading cause of dasatinib (DAS) discontinuation. However, the pathogenic mechanism of this adverse event (AE) is unknown and its management unclear. We investigated if a DAS dose reduction after the first PE would prevent the recurrence of this AE. We retrospectively collected data on all the cases of PE in CML-chronic phase (CP) DAS-treated patients from November 2005 to February 2017 in 21 Italian hematological centers. We identified 196 cases of PE in a series of 853 CML-CP DAS-treated patients (incidence 23...

AIMS: We aimed to assess determinants of anorexia, that is loss of appetite in patients with heart failure (HF) and aimed to further elucidate the association between anorexia, functional capacity, and outcomes in affected patients. METHODS AND RESULTS: We assessed anorexia status among 166 patients with HF (25 female, 66 ± 12 years) who participated in the Studies Investigating Co-morbidities Aggravating HF. Anorexia was assessed by a 6-point Likert scale (ranging from 0 to 5), wherein values ≥1 indicate anorexia...

PURPOSE: Incorporating high dielectric constant (HDC) materials into radiofrequency (RF) coils has been shown to effectively improve RF coil performance at 7 and 3 T because of the induced displacement current in the high dielectric constant materials. The displacement current is proportional to the RF field frequency and permittivity of the material. The aim of this paper is to investigate the effect of high dielectric constant materials with even greater permittivity on the RF field at 1...

Access to antiretrovirals has increased the life expectancy of patients living with HIV. However, HIV-viral hepatitis coinfections in countries endemic for these infections make management more difficult. To determine the extent of these coinfections in Gabon, we investigated markers of hepatitis B, C, and E viruses in 762 adults infected with HIV-1 by ELISA. We used real-time PCR to quantify plasma HBV DNA (HBV VL) and amplified HCV and HEV RNA by nested RT-PCR and PCR.The seroprevalence of chronic hepatitis B infection was 9...

POEMS syndrome is a rare paraneoplastic condition, with a poorly understood pathogenesis. High dose chemotherapy followed by autologous stem cell transplantation (ASCT) has been reported to be an effective therapeutic option for patients with good performance status. Here, we review the role of ASCT for POEMS syndrome and discuss indications together with advantages and disadvantages, and related issues such lenalidomide given before or after ASCT, VEGF levels as a marker of disease, and different regimens for stem cell mobilization...

Muscle senescence is a complex mechanism that is usually associated with a decrease in mass, strength and velocity of contraction. This state, known as sarcopenia, is a multifactorial process and it may be the consequence of several events, including accumulation of oxidative stress. The role of oxidative stress in the physiopathology of skeletal muscle is quite complex. Transiently increased levels of oxidative stress might reflect a potentially health promoting process, while an uncontrolled accumulation might have pathological implication...
