We found that the survival of the insidiosus flower bug, but not the convergent lady beetle, was reduced after consuming aphids reared on thiamethoxam-treated plants compared to untreated plants. Survival reduction of the insidiosus flower bug was observed only during the first weeks after thiamethoxam application; no reduction occurred 28 d after treatment or beyond. These results demonstrate that a systemic application of thiamethoxam could be compatible with convergent lady beetles and insidiosus flower bugs, if the time of predator release does not coincide with thiamethoxam activity. These findings are critical for the development of future pest control programs that integrate biological and chemical control.Data from three experiments conducted to evaluate the effects of increasing available P in swine diets were used to compare two different bone processing methods. Our objective was to determine if the procedures influenced treatment differences and the ability to detect changes in the percentage bone ash. In each experiment, pigs (nursery pigs in experiments 1 and 2, and finishing pigs in experiment 3) were fed a wide range of available phosphorus levels provided from either increasing monocalcium P or added phytase. At the completion of each experiment, a subset of pigs was euthanized, and either fibulas (experiments 1 and 2) or metacarpals (experiment 3) were collected to determine the percentage bone ash. Bones were processed by cleaning away all soft tissues followed by ether extraction for 7 d (defatted), or no lipid extraction (non-defatted), and then ashed. In nursery and finishing pigs, defatted bones had increased (P 0.10) for nursery pigs; however, a linear interaction was detected (P less then 0.05) in percentage bone ash for grow-finish pigs. This response was minimal and likely due to increased variation observed in grow-finish pigs when bones were not defatted. The processing method did not affect the ability to detect differences among treatments as a result of changing dietary P concentrations in the nursery or grow-finish pigs. In summary, either non-defatted or defatted bone processing methods can be used to determine bone ash weight and percentage bone ash as a way to assess bone mineralization and dietary treatment differences in nursery pigs; however, the increased variation observed in mature pigs suggests that defatted bone processing is the preferred method for grow-finish pigs.
We examined the prognostic significance of circulating tumor cell (CTC) dynamics during treatment in metastatic breast cancer (MBC) patients receiving first-line chemotherapy.
Serial CTC data from 469 patients (2,202 samples) were used to build a novel latent mixture model to identify groups with similar CTC trajectory (tCTC) patterns during the course of treatment. Cox regression was used to estimate hazard ratios for progression-free survival (PFS) and overall survival (OS) in groups based on baseline CTCs (bCTC), combined CTC status at baseline to the end of cycle 1 (cCTC), and tCTC. Akaike Information Criterion (AIC) was used to select the model that best predicted PFS and OS.
Latent mixture modeling revealed 4 distinct tCTC patterns undetectable CTCs (tCTCneg, 56.9% ), low (tCTClo, 23.7%), intermediate (tCTCmid, 14.5%), or high (tCTChi, 4.9%). Patients with tCTClo, tCTCmid and tCTChi patterns had statistically significant inferior PFS and OS compared to those with tCTCneg (P<.001). AIC indicatedy be utilized for fine-tuning of CTC-based risk-stratification strategies to guide future prospective clinical trials in MBC.
The QuitNic pilot trial aimed to test the feasibility of providing a nicotine vaping product (NVP) compared with combination nicotine replacement therapy (NRT) to smokers upon discharge from a smoke-free residential substance use disorder (SUD) treatment service.
QuitNic was a pragmatic two-arm randomized controlled trial. At discharge from residential withdrawal, 100 clients received telephone Quitline behavioral support and either 12-week supply of NRT or an NVP. Treatment adherence and acceptability, self-reported abstinence, cigarettes smoked per day (CPD), frequency of cravings, and severity of withdrawal symptoms were assessed at 6 and 12 weeks. Results are reported for complete cases and for abstinence outcomes, penalized imputation results are reported where missing is assumed smoking.
Retention on was 63% at 6 weeks and 50% at 12 weeks. At 12 weeks, 68% of the NRT group reported using combination NRT while 96% of the NVP group used the device. Acceptability ratings for the products were high in 12 weeks postdischarge. The results have significant public health implications for providing quit support following discharge from SUD treatment.A good quality and amount of sleep are fundamental to preserve cognition and affect. New evidence also indicates that poor sleep is detrimental to brain myelination. In this study, we test the hypothesis that sleep quality and/or quantity relate to variability in cognitive and emotional function via the mediating effect of interindividual differences in proxy neuroimaging measures of white matter integrity and intracortical myelination. By employing a demographically and neuropsychologically well-characterized sample of healthy people drawn from the Human Connectome Project (n = 974), we found that quality and amount of sleep were only marginally linked to cognitive performance. In contrast, poor quality and short sleep increased negative affect (i.e. anger, fear, and perceived stress) and reduced life satisfaction and positive emotionality. At the brain level, poorer sleep quality and shorter sleep duration related to lower intracortical myelin in the mid-posterior cingulate cortex (p = 0.038), middle temporal cortex (p = 0.024), and anterior orbitofrontal cortex (OFC, p = 0.034) but did not significantly affect different measures of white matter integrity. LY2874455 ic50 Finally, lower intracortical myelin in the OFC mediated the association between poor sleep quality and negative emotionality (p less then 0.05). We conclude that intracortical myelination is an important mediator of the negative consequences of poor sleep on affective behavior.
