The Development of an Interpersonal Stressors Scale: Identifying Self-Imposed and Other-Imposed Interpersonal Stressors.

While there has been research focused on interpersonal relationships and their impact on stress and well-being, no instrument has been developed to comprehensively evaluate interpersonal stressors. This research sought to develop and validate an Interpersonal Stressors Scale (ISS) for Chinese college students through three studies. Focus groups were used to generate the initial item pool (Study 1).

Gentamicin-Containing Collagen Implant May Reduce Surgical Site Infections After Open Infrainguinal Arterial Revascularization.

Background: Deep-space surgical site infections carry significant morbidity and mortality. The evidence for gentamicin-containing collagen implants at reducing surgical site infections in open infrainguinal arterial surgery is limited. This study examined whether gentamicin-containing collagen implants reduces 30-day surgical site infections and their severity following open infrainguinal arterial surgery.

How to Prevent Surgical Site Infection in Vascular Surgery: A Review of the Evidence.

Background: This review aims to identify and review the current evidence for preventing postoperative surgical site infections in abdominal aortic aneurysm surgery or infrainguinal arterial surgery.

Methods: Extended literature review of clinical trials that examined the prevention of postoperative surgical site infections in abdominal aortic aneurysm or infrainguinal arterial surgery. Searches were conducted on Ovid MEDLINE (1950 - 13 March 2020) using key terms for vascular surgery, surgical site infections and specific preventative techniques.

Rat behavior and dopamine release are modulated by conspecific distress.

Rats exhibit 'empathy' making them a model to understand the neural underpinnings of such behavior. We show data consistent with these findings, but also that behavior and dopamine (DA) release reflects subjective rather than objective evaluation of appetitive and aversive events that occur to another. We recorded DA release in two paradigms: one that involved cues predictive of unavoidable shock to the conspecific and another that allowed the rat to refrain from reward when there were harmful consequences to the conspecific.

Single Neurons in Anterior Cingulate Cortex Signal the Need to Change Action During Performance of a Stop-change Task that Induces Response Competition.

Several human imaging studies have suggested that anterior cingulate cortex (ACC) is highly active when participants receive competing inputs, and that these signals may be important for influencing the downstream planning of actions. Despite increasing evidence from several neuroimaging studies, no study has examined ACC activity at the level of the single neuron in rodents performing similar tasks. To fill this gap, we recorded from single neurons in ACC while rats performed a stop-change task.

Prior Cocaine Self-Administration Increases Response-Outcome Encoding That Is Divorced from Actions Selected in Dorsal Lateral Striatum.

Dorsal lateral striatum (DLS) is a highly associative structure that encodes relationships among environmental stimuli, behavioral responses, and predicted outcomes. DLS is known to be disrupted after chronic drug abuse; however, it remains unclear what neural signals in DLS are altered. Current theory suggests that drug use enhances stimulus-response processing at the expense of response-outcome encoding, but this has mostly been tested in simple behavioral tasks.
