These data show how temporal expectations prepare visual working memory for behavior and shed new light on the electrophysiological markers of both temporal expectation and working memory.Previous research has shown that stress can affect emotion processing in a variety of settings. However, little attention has been paid to the effects of stress on emotional decision-making. The present study addressed this question by exposing healthy young participants either to a stressor (n = 30)-socially evaluated cold pressor task- or a non-stressful control task (n = 30). Subsequently, participants completed a computerized decision-making task in which they could compare the obtained factual outcome with a non-obtained counterfactual outcome. Saliva samples were taken at four time points over the course of the experiment and used to analyze cortisol levels. Results revealed that acute stress induced reliable salivary cortisol increase over the experimental task. At the outcome delivery stage, acute stress amplified negative emotions induced by the counterfactual comparison. At the choice stage, under stress, participants were more likely to make regret-averse decisions. The findings that acute stress amplifies both experienced and anticipated regret is consistent with dual process frameworks such that stress tilts decision-making toward more emotional and intuitive processing. Lay summary Stress is thought to affect emotional processing. The present study investigated the effects of acute stress on emotional decision making using a typical counterfactual decision making task. Acute stress amplified both experience and anticipation of regret, consistent with the dual process frame that stress tilts decision-making toward more emotional and intuitive processing.Opioid use, misuse, and risky use contribute to a critically important and complex crisis in current healthcare. Consequences of long-term opioid use, including opioid induced hyperalgesia, physical dependence, and opioid use disorder, can be considered iatrogenic, or partially iatrogenic, in cases where therapeutic opioid exposures were contributory. Research investigation and presumptive clinical action are needed to attenuate the iatrogenic component of the opioid crisis; treatment of individuals already suffering from opioid use disorder will not prevent incident cases. This work will be challenged by a remarkably high degree of complexity involving myriad and highly variable factors along the continuum from initial opioid exposure to long-term opioid use. An organized view of this complex problem should accelerate the pace of innovation and facilitate clinical implementation of research findings. Herein, we propose a theoretical framework and modern nomenclature for characterizing therapeutic opioid exposure and the degree to which it contributes iatrogenically to adverse outcomes. In doing so, we separate the role of exposure from other factors contributing to long-term opioid use, clarify the relationship between opioid exposure and outcomes, emphasize that exposure source is an important consideration for health services research and practice in the areas of pain treatment and opioid prevention, and recommend terminology necessary to quantify therapeutic opioid exposure separately from nonmedical exposure.

In amyotrophic lateral sclerosis (ALS), early recognition of nocturnal hypoventilation (NH) is essential to start noninvasive ventilation (NIV), but nocturnal transcutaneous PCO

(PtcCO

) is difficult to monitor. Usefulness of respiratory and muscular function test in the prediction of NH has been explored without distinguishing among ALS phenotypes. We evaluated cross-sectional relationships between functional tests and nocturnal PCO

, and the best predictors of NH, separately in patients with spinal and bulbar onset of ALS.

ALS patients candidate to NIV were recruited. Diurnal respiratory and muscular function tests and nocturnal polysomnography with PtcCO

monitoring were performed. NH was defined as peak PtcCO

>49 mm Hg.

Thirty-six patients with spinal and 11 with bulbar onset ALS were included. Nocturnal oxygen saturation and PtcCO

, and proportion of subjects with NH were similar in each group (spinal 50%; bulbar 45.5%). Significant differences between groups were found in forced vitaland sniff nasal inspiratory pressure (SNIP) (p = 0.007), but not in diurnal arterial blood gases. In the spinal group, SNIP and Base Excess (BE) independently predicted nocturnal PtcCO2 (R2 0.59, p  less then  0.0001). In the bulbar group only SNIP was correlated to PtcCO2, but it varied little in relationship to PtcCO2 changes. Conclusions Respiratory and muscle function parameters are differently related to NH in ALS patients with spinal and bulbar presentation. SNIP and BE may be helpful to reveal NH in spinal patients, while in bulbar patients no respiratory or muscle function tests may reliably predict NH.Glyphosate, or N-phosphomethyl(glycine), is an organophosphorus compound and a competitive inhibitor of the shikimate pathway that allows aromatic amino acid biosynthesis in plants and microorganisms. Its utilization in broad-spectrum herbicides, such as RoundUp®, has continued to increase since 1974; glyphosate, as well as its primary metabolite aminomethylphosphonic acid, is measured in soils, water, plants, animals and food. In humans, glyphosate is detected in blood and urine, especially in exposed workers, and is excreted within a few days. It has long been regarded as harmless in animals, but growing literature has reported health risks associated with glyphosate and glyphosate-based herbicides. In 2017, the International Agency for Research on Cancer (IARC) classified glyphosate as “probably carcinogenic” in humans. However, other national agencies did not tighten their glyphosate restrictions and even prolonged authorizations of its use. There are also discrepancies between countries’ authorized level of its global utilization.

ALSFRS-R is 12-item scale used to assess disability and to measure disease progression in ALS patients. Dibutyryl-cAMP purchase The objective is to validate the Arabic version of ALSFRS-R based on the original English version.

This is a cross sectional study. ALSFRS-R was administered to 162 Egyptian patients with ALS after being translated in Arabic, and reapplied after 1 week. Patients were recruited from 2 centers Neuromuscular unit, Ain Shams University hospitals and the specialized ALS clinic which is located at the international medical center (IMC).

No significant differences were found between the application and reapplication of the scale (

 = 0.5). The linear regression and internal consistency that were measured by Pearson correlation and alpha Conbrach respectively were significant.

The Arabic version of the ALSFRS-R proposed by the current was proven to be reproducible and valid among Egyptian ALS patients. Thus, it will provide a useful tool for professionals to evaluate Arabic speaking patients in clinical practice and research.
