Methylphenidate (MPH) remains the only accessible psychostimulant used in France in the attention and behavior disturbances of attention deficit disorder with or without hyperactivity (ADHD). Its prescription has been extended during the past decade to other neurodevelopmental disorders in children and adolescents, also associated with a deficit of attentional resources or, more broadly, fragility of executive functions. Despite its efficiency, validated by more than 400 randomized controlled and double-blind studies, and the good tolerance of MPH in these indications, this treatment remains limited in France because of many fears and other prejudices on the part of medical practitioners and/or families...

Among 64 uropathogenic Escherichia coli (UPEC) isolated from 13 cats and 51 dogs, 35 were extended-spectrum beta-lactamase (ESBL) producers, and 29 were non-ESBL producers. Forty-six (71.9%) of the isolates were multidrug resistant (MDR). Among the ESBL producers, blaCTX-M-15 (n = 17/48.6% of the blaESBLs ), blaCTX-M-1 (n = 10/28.6%), blaCTX-M-55 (n = 4/11.4%), blaCTX-M-14 (n = 3/8.6%), and blaCTX-M-27 (n = 1/2.9%) were identified. The plasmid-mediated fluoroquinolone resistance genes aac(6')-Ib-cr, qnrB and the azithromycin resistance gene mph(A) were detected in 17 (26...

AIM: The aim was to characterize patterns of Methylphenidate (MPH) use in France in both children and adults over a three year period. METHODS: Using the French General Health Insurance database limited to two areas covering approximately 4 million individuals, we made up a cohort of incident MPH users between July 2010 and June 2013. Splitting them into distinct age groups ( [18-24]; [25;49]; >=50 years olds for adults and less than 6 years old, [6-11] and [12;17] for children), we described these populations at MPH initiation and during follow-up according to duration of treatment, quantities dispensed, and co-prescription with Central Nervous System (CNS) drugs...

Since the plasmid-mediated polymyxin resistance gene mcr-1 was first reported in Escherichia coli and Klebsiella pneumoniae in China, only one mcr-1-positive isolate of Shigella sonnei, containing inactivated mcr-1, has been reported worldwide. Here, we screened 1650 historical S. sonnei strains isolated from 2003 to 2015 in China for mcr-1. We determined the antimicrobial susceptibilities and resistance genes of mcr-1-positive isolates and investigated the transferability of polymyxin resistance by plasmid conjugation...

BACKGROUND: Observational studies of switching from branded to generic formulations of the same drug substance often lack appropriate comparators for the subjects who switched. Three generic formulations were deemed equivalent to Concerta: an authorized generic (AG) identical except for external packaging, and two other generics (EG). OBJECTIVE: Compare the incidence of a combined endpoint (switching back to Concerta, changing the use of immediate release methylphenidate (MPH), stopping all long-acting methylphenidate, or starting a new medication) among people switched from Concerta to the AG versus the EG...

The complete nucleotide sequences of six IMP-4-encoding plasmids recovered from Enterobacteriaceae of wildlife origin were characterized. Sequencing data showed that plasmids of different incompatibility groups (IncM, IncI1, IncF, and nontypeable [including an IncX5_2 and two pPrY2001-like]) carried the bla IMP-4 -carrying integrons, In809 or In1460. Most of the plasmids carried mph (A) region, and chrA -like, aac(3)-IId and bla TEM-1b genes. Finally, plasmid analysis revealed the involvement of two different, IS 26 - and Tn 1696 -associated, mechanisms in the mobilization of IMP-4-encoding integrons...

Methylphenidate (MPH) is a first-line stimulant drug to treat attention deficit hyperactivity disorder (ADHD). Overdiagnosis of ADHD and MPH abuse lead to serious concerns about the possible long-term adverse consequences of MPH in healthy children and adolescents. We aimed to evaluate MPH effects in adolescent male Wistar rats (postnatal day 40) using an oral dose scheme (2 daily MPH doses 5 mg/kg in a 5% sucrose solution, 5 h apart, for 7 days) that mimics the therapeutic doses given to human adolescents...

Abnormalities in the cerebellar circuitry have been suggested to contribute to some of the symptoms associated with attention deficit hyperactivity disorder (ADHD). The psychostimulant methylphenidate (MPH) is the major drug for treating this condition. Here, the effects of acute (2.0 mg/kg and 5.0 mg/kg) and chronic (2.0 mg/kg, twice daily for 15 days) MPH treatments were investigated in adolescent (35-40 days old) rats on monoaminergic and metabolic markers in the cerebellum. Data acquired indicates that acute MPH treatment (2...

Methylphenidate (MPH) has been shown to modulate the amplitude of the no-go P3 component of the event-related potential (ERP; Øgrim, Aasen, & Brunner, 2016). Using group independent component analysis, the no-go P3 from a cued go/no-go task has been separated into two sub-components (Brunner et al., 2013). This study investigated whether sub-components of the no-go P3 could be identified in children with ADHD, and how MPH modulates their amplitudes. ERPs were registered twice (on/off MPH) in 57 children with ADHD classified as medication responders in a four-week medication trial...

PURPOSE: Exercise elicits early adaptation of coronary vessels enabling the coronary circulation to respond adequately to higher flow demands. We hypothesized that short-term daily exercise induces biomechanical and functional remodeling of the coronary resistance arteries related to pressure. METHODS: Male rats were subjected to a progressively increasing 4-week treadmill exercise program (over 60 min/day, 1 mph in the final step). In vitro pressure-diameter measurements were performed on coronary segments (119 ± 5 μm in diameter at 50 mm Hg) with microarteriography...

Purpose/Aim: Powdered hemostats have been widely adopted for their ease-of-use; however, their efficacy has been limited resulting in applications restricted to low-level bleeds. This study investigates the use of bovine-derived gelatin particles (BGP) as a standalone hemostatic powder and compare BGP to commercially available microporous polysaccharide hemospheres (MPH). MATERIALS AND METHODS: The powders were investigated for their hemostatic efficacy in a heparinized pre-clinical bleeding model limited to grade 1 and 2 bleeds on a validated intraoperative bleeding scale, which represents the accepted, clinical use of hemostatic powders...

Interleukin-8 (IL-8, CXCL8) belongs to major chemokines to stimulate migration of neutrophils and monocytes/macrophages (Mc/Mphs) into the inflammation sites. We studied the direct effects of IL-8 on the functionality of human Mc/Mphs in vitro. CD14-positive cells were isolated from human peripheral blood mononuclear cells (PBMCs) by positive magnetic separation and were further cultured with or without lipopolysaccharide (LPS, 1.0 μg/ml) for 24 h. We showed that upon LPS activation of Mc/Mphs, IL-8 reduced markedly both the percentages and median fluorescence intensity (MFI) of CD16 (FcγRIII)-positive cells among CD14high cells, as well as in cells that reduced the expression of СD14 during their culturing...

Methylphenidate (MPH) is a widely prescribed drug for the treatment of attention-deficit hyperactivity disorder. Findings in the literature suggest that the effects of MPH on memory may result from increased extracellular levels of norepinephrine (NE) and dopamine (DA). Here, we report that the systemic administration of MPH before the acquisition phase in a social discrimination task impaired the retrieval of the social recognition memory (SRM), but made it state-dependent: another administration of MPH before the retention test recovered the SRM...
