Sleep Mediates the Association Between PTSD Symptoms and Chronic Pain in Youth

Symptoms of post-traumatic stress disorder (PTSS) and chronic pain have been shown to co-occur at high rates in adolescents and this co-occurrence is linked to worse pain and quality of life. Sleep disturbance has been posited as a mechanism underlying this co-occurrence in conceptual models of mutual maintenance. This study examined the mediating role of sleep in the relationship between PTSS and pain in youth (aged 10–17 years) with chronic pain. Ninety-seven participants completed measures of PTSS, pain (intensity and interference), anxiety symptoms, and sleep quality, in addition to demographic characteristics. Mediation models were conducted. Findings revealed that, over and above the influence of associated demographic characteristics (age, race) and anxiety symptoms, sleep quality partially mediated the relationships between PTSS and pain intensity and interference for youth with chronic pain. Specifically, higher levels of PTSS was linked to higher levels of pain intensity and pain interference, and these relationships were partially explained by poor sleep quality. Findings highlight the potential mechanistic role of sleep in explaining the co-occurrence of chronic pain and PTSS and suggest sleep might be an important target in future interventions.

Exploring the Role of Negative Cognitions in the Relationship Between Ethnicity,Sleep, and Pain in Women With Temporomandibular Joint Disorder

Negative cognitions are central to the perpetuation of chronic pain and sleep disturbances. Patients with temporomandibular joint disorder (TMJD), a chronic pain condition characterized by pain and limitation in the jaw area, have a high comorbidity of sleep disturbances that possibly exacerbate their condition. Ethnic group differences are documented in pain, sleep, and coping, yet the mechanisms driving these differences are still unclear, especially in clinical pain populations. We recruited 156 women (79% white, 21% African American) diagnosed with TMJD as part of a randomized, controlled trial evaluating the effectiveness of interventions targeting sleep and pain catastrophizing on pain in TMJD. Analysis of baseline data demonstrated that, relative to white participants, African Americans exhibited higher levels of clinical pain, insomnia severity, and pain catastrophizing, yet there was no ethnic group difference in negative sleep-related cognitions. Mediation models revealed pain catastrophizing, but not sleep-related cognitions or insomnia severity, to be a significant single mediator of the relationship between ethnicity and clinical pain. Only the helplessness component of catastrophizing together with insomnia severity sequentially mediated the ethnicity–pain relationship. These findings identify pain catastrophizing as a potentially important link between ethnicity and clinical pain and suggest that interventions targeting pain-related helplessness could improve both sleep and pain, especially for African American patients.Perspective:Pain-related helplessness and insomnia severity contribute to ethnic differences found in clinical pain among woman with TMJD. Findings can potentially inform interventions that target insomnia and catastrophizing to assist in reducing ethnic disparities in clinical pain.     

Weight status,diet quality,perceived stress,and functional health of caregivers of children with autism spectrum disorder

1 Purpose

Caring for children with autism spectrum disorder (ASD) can be highly demanding and can put significant strain on caregivers. To date, little is known about the extent to which caregivers of children with ASD experience increased levels of stress which may adversely affect health outcomes. The purpose of this secondary analysis was to compare caregivers of children with ASD and caregivers of typically developing children (TDC) in weight status, diet quality, perceived stress related to the parenting role, and functional health and well‐being.

2 Design and methods

Caregivers of 25 children with ASD and 30 TDC completed the 2005 Block Food Frequency Questionnaire, the 36‐item Short Form of the Parenting Stress Index (PSI/SF), and the Short Form Health Survey (SF‐36) and had their heights and weights measured during an onsite visit. Diet quality was assessed using the Healthy Eating Index (HEI)‐2010 and its dietary components and conformance to the 2010 Dietary Guidelines for Americans.

3 Results

ASD caregivers did not differ significantly from TDC caregivers in body mass index or overweight/obesity prevalence (p ≥ .28), even when controlling for covariates. In univariate analyses, ASD caregivers consumed significantly fewer empty calories from solid fats, alcohol, and added sugars than TDC caregivers (p = .03), but they did not differ significantly in any other dietary outcomes including nutrient adequacy (p ≥ .10) and mean total HEI scores (p = .20). ASD caregivers, when compared to TDC caregivers, reported significantly greater parenting stress for the subscales difficult child and parent–child dysfunctional interaction as well as total stress (p < .001). In addition, 56% of ASD caregivers compared with 6.7% of TDC caregivers showed clinically significant levels of stress (p < .0001); a finding which remained statistically significant when controlling for covariates. ASD and TDC caregivers did not differ significantly in any SF‐36 health domains related to functional health and well‐being (p ≥ .10).

4 Practice implications

Despite higher reported levels of stress, ASD caregivers did not differ significantly from TDC caregivers in diet‐ and health‐related outcomes. Nurses and other health professionals should use comprehensive screening tools to assess overall caregiver stress and levels of resilience.     

康复护理路径应用在脑卒中患者吞咽障碍中的临床研究

目的 探讨康复护理路径(RCNP)应用在脑卒中吞咽障碍患者中的效果。方法 选取2014年5月~2017年6月在上海市松江区泗泾医院神经内科实施RCNP护理的脑卒中吞咽障碍患者600例作为观察组,选取2014年5月~2017年6月在我院接受常规护理的脑卒中吞咽障碍患者600例作为对照组。统计两组患者护理后洼田吞咽能力评分、口腔期评分、咽期评分、护理效果、住院天数、住院费用、健康知识知晓率、满意度。结果 观察组口腔期评分、咽期评分、洼田吞咽能力评分分别为(2.6±0.6)、(2.5±0.5)分、(4.3±1.1),对照组为(1.8±0.5)、(1.9±0.5)、(3.5±0.7)分,两组比较差异有统计学意义(P ＜ 0.01);观察组总有效率为90.0%(540/600),对照组总有效率为73.0%(438/600),差异有统计学意义(P ＜ 0.05);观察组住院费用、住院天数均明显少于对照组(Ｐ＜0.01);观察组患者满意度(98.67％)和健康知晓率(96.5％)均高于对照组(71.0％,73.67％,Ｐ＜0.01)。结论 RCNP的应用,明显改善吞咽障碍患者的吞咽功能,降低住院费用及住院天数,提高患者的生活质量,减轻患者的经济和心理负担。值得推广应用。     

A new manometry device for evaluating the sphincter of Oddi using a fiber-optic pressure sensor

Introduction: Although measuring the pressure of the sphincter of Oddi and the bile duct is considered to be an important examination, called Sphincter of Oddi manometry (SOM), some complications related to the SOM device remain unsolved.

Material and methods: To decrease adverse complications, we developed a 0.46?mm manometry and we performed some in vitro studies.

Results: We successfully developed a 0.46?mm SOM. The diameter is the thinnest size used in endoscopic examinations. The results of in vitro studies show the suitability as SOM.

Conclusion: This device will decrease the risks related to SOM examination. To confirm the safety and feasibility, further studies including in vivo studies will be needed.     

Flibanserin toxicity in a toddler following ingestion

Introduction: Flibanserin is a medication recently approved by the FDA for treatment of generalized hypoactive sexual desire disorder (HSDD) in premenopausal women. Its mechanism of action is not fully understood but is thought to modulate serotonin receptors and increase levels of norepinephrine and dopamine. While much is known about toxicity of other drugs which affect these systems, there is little information about toxicity of flibanserin at this time.

Case: We present a case of a 2-year-old boy who ingested an estimated 600?mg of his mother’s flibanserin. Following ingestion, the child developed facial twitching and unresponsiveness to pain, concerning for seizure-like activity. In the emergency department (ED) he was found to have hypertension, mydriasis, slurred speech, and normal labs. He responded well to supportive care including administration of benzodiazepines. Shortly after admission to the hospital, his temperature increased to 38.4?°C. Toxicology testing revealed the presence of 1-(3-trifluoromethylphenyl)-piperazine (TFMPP), a flibanserin metabolite. TFMPP is a recreational drug used as an alternative to 3,4-methylenedioxymethamphetamine (more commonly known as “MDMA” or “ecstasy”).

Discussion: This case highlights potential toxicity associated with ingestion of flibanserin.
