Neonatal-onset multisystem inflammatory disease responsive to interleukin-1 beta inhibition

BACKGROUND:Neonatal-onset multisystem inflammatory disease is characterized by fever, urticarial rash, aseptic meningitis, deforming arthropathy, hearing loss, and mental retardation. Many patients have mutations in the cold-induced autoinflammatory syndrome 1 (CIAS1) gene, encoding cryopyrin, a protein that regulates inflammation.METHODS:We selected 18 patients with neonatal-onset multisystem inflammatory disease (12 with identifiable CIAS1 mutations) to receive anakinra, an interleukin-1-receptor antagonist (1 to 2 mg per kilogram of body weight per day subcutaneously). In 11 patients, anakinra was withdrawn at three months until a flare occurred. The primary end points included changes in scores in a daily diary of symptoms, serum levels of amyloid A and C-reactive protein, and the erythrocyte sedimentation rate from baseline to month 3 and from month 3 until a disease flare.RESULTS:All 18 patients had a rapid response to anakinra, with disappearance of rash. Diary scores improved (P<0.001) and serum amyloid A (from a median of 174 mg to 8 mg per liter), C-reactive protein (from a median of 5.29 mg to 0.34 mg per deciliter), and the erythrocyte sedimentation rate decreased at month 3 (all P<0.001), and remained low at month 6. Magnetic resonance imaging showed improvement in cochlear and leptomeningeal lesions as compared with baseline. Withdrawal of anakinra uniformly resulted in relapse within days; retreatment led to rapid improvement. There were no drug-related serious adverse events.CONCLUSIONS:Daily injections of anakinra markedly improved clinical and laboratory manifestations in patients with neonatal-onset multisystem inflammatory disease, with or without CIAS1 mutations

Influence of organic versus inorganic dietary selenium supplementation on the concentration of selenium in colostrum, milk and blood of beef cows

<p>Abstract</p> <p>Background</p> <p>Selenium (Se) is important for the postnatal development of the calf. In the first weeks of life, milk is the only source of Se for the calf and insufficient level of Se in the milk may lead to Se deficiency. Maternal Se supplementation is used to prevent this.</p> <p>We investigated the effect of dietary Se-enriched yeast (SY) or sodium selenite (SS) supplements on selected blood parameters and on Se concentrations in the blood, colostrum, and milk of Se-deficient Charolais cows.</p> <p>Methods</p> <p>Cows in late pregnancy received a mineral premix with Se (SS or SY, 50 mg Se per kg premix) or without Se (control – C). Supplementation was initiated 6 weeks before expected calving. Blood and colostrum samples were taken from the cows that had just calved (Colostral period). Additional samples were taken around 2 weeks (milk) and 5 weeks (milk and blood) after calving corresponding to Se supplementation for 6 and 12 weeks, respectively (Lactation period) for Se, biochemical and haematological analyses.</p> <p>Results</p> <p>Colostral period. Se concentrations in whole blood and colostrum on day 1 <it>post partum </it>and in colostrum on day 3 <it>post partum </it>were 93.0, 72.9, and 47.5 μg/L in the SY group; 68.0, 56.0 and 18.8 μg/L in the SS group; and 35.1, 27.3 and 10.5 μg/L in the C group, respectively. Differences among all the groups were significant (<it>P </it>< 0.01) at each sampling, just as the colostrum Se content decreases were from day 1 to day 3 in each group. The relatively smallest decrease in colostrum Se concentration was found in the SY group (<it>P </it>< 0.01).</p> <p>Lactation period. The mean Se concentrations in milk in weeks 6 and 12 of supplementation were 20.4 and 19.6 μg/L in the SY group, 8.3 and 11.9 μg/L in the SS group, and 6.9 and 6.6 μg/L in the C group, respectively. The values only differed significantly in the SS group (<it>P </it>< 0.05). The Se concentrations in the blood were similar to those of cows examined on the day of calving. The levels of glutathione peroxidase (GSH-Px) activity were 364.70, 283.82 and 187.46 μkat/L in the SY, SS, and C groups, respectively. This was the only significantly variable biochemical and haematological parameter.</p> <p>Conclusion</p> <p>Se-enriched yeast was much more effective than sodium selenite in increasing the concentration of Se in the blood, colostrum and milk, as well as the GSH-Px activity.</p

UK research priority setting for childhood neurological conditions

\ua9 2024 The Author(s). Developmental Medicine &amp; Child Neurology published by John Wiley &amp; Sons Ltd on behalf of Mac Keith Press. Aim: To identify research priorities regarding the effectiveness of interventions for children and young people (CYP) with childhood neurological conditions (CNCs). These include common conditions such as epilepsies and cerebral palsy, as well as many rare conditions. Method: The National Institute for Health and Care Research (NIHR) and the James Lind Alliance (JLA) champion and facilitate priority setting partnerships (PSPs) between patients, caregivers, and clinicians (stakeholders) to identify the most important unanswered questions for research (uncertainties). A NIHR–JLA and British Paediatric Neurology Association collaboration used the JLA PSP methodology. This consisted of two surveys to stakeholders: survey 1 (to identify uncertainties) and survey 2 (a prioritization survey). The final top 10 priorities were agreed by consensus in a stakeholder workshop. Results: One hundred and thirty-two charities and partner organizations were invited to participate. In survey 1, 701 participants (70% non-clinicians, including CYP and parent and caregivers) submitted 1800 uncertainties from which 44 uncertainties were identified for prioritization in survey 2; from these, 1451 participants (83% non-clinicians) selected their top 10 priorities. An unweighted amalgamated score across participant roles was used to select 26. In the final workshop, 14 health care professionals, 11 parent and caregivers, and two CYP ranked the 26 questions to finalize the top 10 priorities. Ten top priority questions were identified regarding interventions to treat CYP with CNCs and their associated comorbidities, for example, sleep, emotional well-being, and distressing symptoms. Interpretation: The results of this study will inform research into the effectiveness of interventions for children with neurological conditions

A qualitative reading of the ecological (dis)organisation of criminal associations. The case of the ?Famiglia Basilischi? in Italy

This paper combines the theoretical foundations of organisational ecology - one of the most important approaches in economic sociology - with classic criminological theories to interpret the birth, evolution and death of criminal associations. This mixed approach will support the interpretation of organised crime groups as phenomena strictly linked to the environment as well as to other competitors in criminal markets. This paper analyses the birth, evolution and death of a criminal association in Basilicata, Southern Italy, known as the ?Famiglia Basilischi?. The case is exemplary of how ecological conditions affect the success or failure of a newly formed criminal association. These conditions can therefore be indicators to interpret organised criminal activities in similar environments

Institutional constraints and ecological processes: Evolution of foreign-invested enterprises in the Chinese construction industry, 1993-2006

In the current study, expansion of foreign investment in transition economies such as China is analyzed as an organizational selection process in a community ecology setting. Insights from organizational ecology are used to explain how institutional forces constrain ecological processes, together driving the evolution of the population size of foreign-invested enterprises (FIEs), privately held domestic firms, and state-owned domestic organizations. We argue that the variation in the relative forces of ecological processes and institutional constraints across FIEs and their domestic rivals accounts for the expansion of FIEs in China. On the one hand, in many transition economies, institutional constraints are imposed on foreign enterprises by regulation that limits FDI opportunities. On the other hand, after entry, foreign enterprises can benefit from their competitive advantages in their ecological struggle against domestic rivals. This logic produces different sets of hypotheses as to foreign enterprises’ density and sales growth, in interaction with domestic organizations. Using a data set of the Chinese construction industry in 29 provinces over the 1993–2006 period, estimation of a partial adjustment growth model produces support for our theoretical claim
