Nicotine addiction, through smoking, is the principal cause of preventable mortality worldwide. Human genome-wide association studies have linked polymorphisms in the CHRNA5-CHRNA3-CHRNB4 gene cluster, coding for the α5, α3, and β4 nicotinic acetylcholine receptor (nAChR) subunits, to nicotine addiction. β4*nAChRs have been implicated in nicotine withdrawal, aversion, and reinforcement. Here we show that β4*nAChRs also are involved in non-nicotine-mediated responses that may predispose to addiction-related behaviors. β4 knock-out (KO) male mice show increased novelty-induced locomotor activity, lower baseline anxiety, and motivational deficits in operant conditioning for palatable food rewards and in reward-based Go/No-go tasks. To further explore reward deficits we used intracranial self-administration (ICSA) by directly injecting nicotine into the ventral tegmental area (VTA) in mice. We found that, at low nicotine doses, β4KO self-administer less than wild-type (WT) mice. Conversely, at high nicotine doses, this was reversed and β4KO self-administered more than WT mice, whereas β4-overexpressing mice avoided nicotine injections. Viral expression of β4 subunits in medial habenula (MHb), interpeduncular nucleus (IPN), and VTA of β4KO mice revealed dose- and region-dependent differences: β4*nAChRs in the VTA potentiated nicotine-mediated rewarding effects at all doses, whereas β4*nAChRs in the MHb-IPN pathway, limited VTA-ICSA at high nicotine doses. Together, our findings indicate that the lack of functional β4*nAChRs result in deficits in reward sensitivity including increased ICSA at high doses of nicotine that is restored by re-expression of β4*nAChRs in the MHb-IPN. These data indicate that β4 is a critical modulator of reward-related behaviors.

SIGNIFICANCE STATEMENT Human genetic studies have provided strong evidence for a relationship between variants in the CHRNA5-CHRNA3-CHRNB4 gene cluster and nicotine addiction. Yet, little is known about the role of β4 nicotinic acetylcholine receptor (nAChR) subunit encoded by this cluster. We investigated the implication of β4*nAChRs in anxiety-, food reward- and nicotine reward-related behaviors. Deletion of the β4 subunit gene resulted in an addiction-related phenotype characterized by low anxiety, high novelty-induced response, lack of sensitivity to palatable food rewards and increased intracranial nicotine self-administration at high doses. Lentiviral vector-induced re-expression of the β4 subunit into either the MHb or IPN restored a "stop" signal on nicotine self-administration. These results suggest that β4*nAChRs provide a promising novel drug target for smoking cessation.

Source: Infobae - El cambio climático es probablemente el mayor desafío ambiental y social que enfrenta la humanidad, y que fue generado por el ser humano. Es un problema global que se resuelve en forma global, en donde existen muchos matices que hacen difícil el consenso entre los países respecto a las decisiones que deben tomarse. Sin embargo, todos reconocen el siguiente principio como marco de discusión: principio de responsabilidades comunes pero diferenciadas. Este principio reconoce que todos los países tienen responsabilidad común de solucionar el problema, aunque no todos en el mismo nivel y grado, ya que históricamente los países desarrollados han contaminado más a efecto de construir sus economías que aquellos que están en vías de desarrollo. Y no todos los países tienen la misma capacidad y recursos para enfrentar la problemática.

Corticosteroids inhibit the expression of many proinflammatory cytokines released during the course of community-acquired pneumonia infection. Corticosteroids have been found in some studies to be associated with improved clinical outcomes in adults with pneumonia. No studies have investigated corticosteroid use in children with pneumonia.

Results showed that corticosteroid treatment in children with pneumonia is common and its use is highly variable across institutions. Although corticosteroid therapy may benefit children with acute wheezing treated with β-agonists, corticosteroid therapy may lead to worse outcomes for children without wheezing.

Most childhood HIV is acquired through perinatal transmission, some of which is preventable. Practitioners need to understand what proportion of perinatally acquired HIV infections are attributable to missed prevention opportunities.

Missed prevention opportunities include lack of early HIV testing for pregnant women; suboptimal use of antiretroviral medications during pregnancy, labor, or delivery or for the neonate; breastfeeding; and vaginal delivery when maternal viral load was ≥1000 copies/mL. (Read the full article)

High-grade vesicoureteral reflux is a risk factor for impaired renal function. Diagnosis by voiding cystourethrography is invasive and highly uncomfortable. As only a minority of children show high-grade vesicoureteral reflux, this exposes the majority to unnecessary distress.

This case-control study proved that high-grade vesicoureteral reflux is identifiable with high sensitivity using urinary proteome analysis, based on capillary electrophoresis coupled to mass spectrometry in a cohort suspected of having vesicoureteral reflux, thus sparing the majority of children from invasive diagnostics.

Clinic-based weight control treatments for youth have largely been designed for preadolescent children and their families by using family-based care, a strategy that may be less appealing to adolescents as they become increasingly motivated by peer acceptance rather than parental influence.

To our knowledge, this is the first study to demonstrate the efficacy of a primary care–based, multicomponent lifestyle intervention specifically tailored for overweight adolescent females and demonstrating a sustained effect (at 12 months) extending beyond the active 5-month intervention.

Infantile colic affects almost 10% of all infants and is characterized by crying and fussing in an otherwise healthy and well-fed infant. Prenatal exposure to tobacco smoking is a risk factor, but it is unclear whether nicotine causes the association.

Infants exposed to nicotine replacement therapy during pregnancy had elevated infantile colic risk of the same magnitude as infants exposed to tobacco smoking. Intrauterine exposure to nicotine may play a causal role in the pathogenesis of infantile colic. (Read the full article)

Early administration of oral corticosteroids is essential for children presenting to emergency departments with moderate to severe acute asthma exacerbations, because subsequent admission need is directly related to time to receipt of systemic steroids, yet delays to administration remain long.

A medical directive allowing nurse initiation of oral corticosteroids before physician assessment was associated with improved quality and efficiency of care provided in the pediatric emergency department by ensuring implementation of evidence-based practice. (Read the full article)

In utero exposure to glucocorticoids in animal models influences vascular development. Studies in young adults have shown that exposure to antenatal glucocorticoids alters glucose metabolism, but it is not known whether there are any cardiovascular effects.

Glucocorticoid exposure is associated with a localized increase in aortic arch stiffness, similar in magnitude to term-born individuals a decade older. The change in stiffness does not relate to changes in glucose metabolism that were also evident in this cohort. (Read the full article)

Most studies on corticoid treatment of respiratory syncytial virus (RSV) respiratory diseases have revealed no beneficial effect. The mechanism by which RSV respiratory-infected patients are insensitive to the antiinflammatory effect of corticosteroids is unknown.

This study helps to understand how a respiratory syncytial viral infection may alter the normal antiinflammatory response to cortisol and the insensitivity to glucocorticoid treatment. The increase expression of β glucocorticoid receptor could be a marker of disease severity. (Read the full article)

In Mexico, substantial declines in childhood diarrhea deaths have been documented since the introduction of the rotavirus vaccine in 2007. However, there is concern of lower vaccine effectiveness in less developed regions of Mexico with higher diarrhea-related mortality.

We documented significant and comparable declines across all 3 regions of Mexico with different levels of development, indicating equitable vaccine distribution to children with varying risk of mortality and reaffirming the beneficial effects of rotavirus vaccination against fatal diarrheal disease.

The ideal management of children with vesicoureteral reflux (VUR) remains a source of debate. There is little evidence to support many of the current management practices for children with VUR who have had 1 or 2 urinary tract infections.

Baseline associations, including bladder and bowel dysfunction and imaging studies, from the largest randomized, controlled trial conducted to date aimed at assessing the value of antimicrobial prophylaxis in children with urinary tract infection and VUR are presented. (Read the full article)

The familial nature of vesicoureteral reflux (VUR) is well recognized. Several studies have shown that siblings of children with VUR are at much higher risk for reflux than the general pediatric population with a reported prevalence between 26% and 50%.

There is increased risk of renal cortical abnormalities in siblings with a previous urinary tract infection, siblings with high-grade VUR, and siblings >1 year of age. This information may be useful when counseling parents about the risk of familial VUR. (Read the full article)

Administration of repeat doses of antenatal glucocorticoids to women at risk for preterm birth after an initial course reduces neonatal morbidity, without affecting rates of neurologic disability in early childhood. However, data on long-term effects on cardiometabolic health are limited.

Exposure to repeat doses of antenatal betamethasone did not increase cardiovascular risk factors at early school age. Clinicians wishing to use repeat antenatal glucocorticoids can be reassured that the risk of future cardiometabolic disease from this therapy is low. (Read the full article)

Application of antenatal corticosteroids to mothers before delivery is highly beneficial to very low birth weight infants. Yet despite widespread quality improvement efforts, many eligible infants fail to receive this therapy.

We demonstrate improvement in antenatal corticosteroid use during the study period. However, significant regional variation persists, which network-level quality improvement efforts might help eliminate. (Read the full article)

Little is known about the impact of tobacco smoke exposure on preterm children with bronchopulmonary dysplasia. It is essential to understand how environmental exposures, such as tobacco smoke, influence respiratory morbidities in this vulnerable population.

Chronic tobacco smoke exposure is common in children with bronchopulmonary dysplasia. In children who required home respiratory support, hair nicotine levels were a better predictor of hospitalization and activity limitation than caregiver self-report. (Read the full article)

Smoking has been found to increase the risk of some specific congenital anomalies; however, results remain inconsistent. Nicotine replacement therapy (NRT) is increasingly being used as for smoking cessation in pregnancy although little is known about its association with congenital anomalies.

Being prescribed NRT while pregnant was not associated with major congenital anomalies (MCA), except a small increase in respiratory anomalies (3/1000 births). This must be considered in context of the rarity of MCAs and higher morbidities in the NRT group. (Read the full article)

Background. CLSI and EUCAST susceptibility breakpoints for voriconazole and C. albicans differ by one dilution (≤0.125 and ≤0.06 mg/l, respectively) whereas the epidemiological cutoff values (ECOFF/ECV) with both methodologies are the same (0.03 mg/L). We therefore determined the pharmacokinetic-pharmacodynamic (PK/PD) breakpoints of voriconazole against C. albicans for both methodologies with an in vitro PK/PD model, which was validated using existing animal PK/PD data.

Methods. Four clinical wild-type and non-wild-type C. albicans isolates (voriconazole MICs 0.008-0.125 mg/l) were tested in an in vitro PK/PD model. For validation purposes, mouse PK were simulated and in vitro PD were compared with in vivo outcome. Human PK were simulated and the exposure-effect relationship fAUC_0-24/MIC was described for EUCAST and CLSI24/48h methods. PK/PD breakpoints were determined using the fAUC_0-24/MIC associated with half-maximal activity (EI₅₀) and Monte Carlo simulation analysis.

Results. The in vitro 24h-PD EI₅₀ of voriconazole against C. albicans were 2.5-5 (1.5-17) fAUC/MIC. However, the 72h-PD were higher, 133 (51-347) fAUC/MIC for EUCAST and 94 (35-252) fAUC/MIC for CLSI. The mean (95% confidence interval) probability of target attainment (PTA) was 100(95-100)%, 97(72-100)%, 83(35-99)%, and 49(8-91)% and 100(97-100)%, 99(85-100)%, 91(52-100)% and 68(17-96)% for EUCAST and CLSI MICs 0.03, 0.06, 0.125, and 0.25 mg/L, respectively. Significantly, >95% PTAs were found for EUCAST/CLSI MICs ≤0.03 mg/ll. For MICs 0.06-0.125 mg/l trough levels 1-4 mg/ll would be required.

Conclusion. A PK/PD breakpoint of C. albicans voriconazole at the ECOFF/ECV of 0.03 mg/L was determined for both EUCAST/CLSI methods, indicating the need for breakpoint harmonization for the reference methodologies.

Bacteria of the genus Campylobacter are major foodborne pathogens which have become increasingly resistant to clinically important antimicrobial agents (1)....

Florfenicol belongs to a class of phenicol antimicrobials widely used as feed additives and for the treatment of respiratory infections. In recent years, increasing resistance to florfenicol has been reported in Campylobacter spp., the leading foodborne enteric pathogen causing diarrheal diseases worldwide. Here, we reported the identification of fexA, a novel mobile florfenicol resistance gene in Campylobacter. Of the 100 Campylobacter jejuni strains isolated from poultry in Zhejiang, China, nine of them were shown to be fexA positive, and their whole genome sequences were further determined by integration of Illumina short-read and MinION long-read sequencing. The fexA gene was found in the plasmid of one strain and chromosomes of eight strains, and its location was verified by S1 nuclease pulsed-field gel electrophoresis (S1-PFGE) and Southern blotting. Based on comparative analysis, the fexA gene was located within a region with the tet(L)-fexA-catA-tet(O) gene arrangement, demonstrated to be successfully transferrable among C. jejuni strains. Functional cloning indicated that acquisition of the single fexA gene significantly increased resistance to florfenicol, whereas its inactivation resulted in increased susceptibility to florfenicol in Campylobacter. Taken together, these results indicated that the emerging fexA resistance is horizontally transferable, which might greatly facilitate the adaptation of Campylobacter in food producing environments where florfenicols are frequently used.
