Exercise Intolerance in Patients With Heart Failure: JACC State-of-the-Art Review

Exercise intolerance is the cardinal symptom of heart failure (HF) and is of crucial relevance, because it is associated with a poor quality of life and increased mortality. While impaired cardiac reserve is considered to be central in HF, reduced exercise and functional capacity are the result of key patient characteristics and multisystem dysfunction, including aging, impaired pulmonary reserve, as well as peripheral and respiratory skeletal muscle dysfunction. We herein review the different modalities to quantify exercise intolerance, the pathophysiology of HF, and comorbid conditions as they lead to reductions in exercise and functional capacity, highlighting the fact that distinct causes may coexist and variably contribute to exercise intolerance in patients with HF.     

Individuals with peripheral vestibulopathy and poor quality of sleep are at a higher risk for falls

IntroductionThere is a lack of scientific studies on the assessment of patients with vestibular disorders associated with sleep quality disorders and its impact on the balance and overall quality of life.Objectivesto assess the impact of the sleep quality on the balance and quality of life of individuals with peripheral vestibulopathies.Methods52 individuals with peripheral vestibulopathies underwent sleep quality assessment through the Pittsburgh sleep quality index, neurotological examination through dizziness handicap inventory and Tetrax posturography (Sunlight Medical Ltd.) in eight sensory conditions. Thirty-two healthy individuals (G3) participated as the control group.ResultsFourteen individuals with vestibulopathy had good quality of sleep (G1) and 38 showed poor quality of sleep (G2) as demonstrated by the Pittsburgh sleep quality index global scores (p = 0.001). The dizziness handicap inventory showed worse impact of the dizziness on the quality of life in G2 when compared to G1 (p  = 0.045). The G₂ showed higher risk of falling in posturography when compared to G3 (p = 0.012) and higher index of postural instability in five sensory conditions in comparison with G3. In the vestibulopathy groups, the worse the sleep quality, the higher the risk of falling (r = 0.352) and the worse the quality of life (r = 0.327).ConclusionIndividuals with peripheral vestibulopathies and poor quality of sleep demonstrate worse balance evidenced by increased postural instability, higher risk of falls and worse perceived quality of life. The quality of sleep is a predictive factor for worse perceived quality of life and for higher risk of falls in individuals with peripheral vestibulopathies.     

Midazolam exposure in the paediatric intensive care unit predicts acute post-traumatic stress symptoms in children

BackgroundClinically significant post-traumatic stress symptoms (PTSS) have been reported in up to a quarter of paediatric intensive care unit (PICU) survivors. Ongoing PTSS negatively impacts children's psychological development and physical recovery. However, few data regarding associations between potentially modifiable PICU treatment factors, such as analgosedatives and invasive procedures, and children's PTSS have been reported.ObjectivesWe sought to investigate the medical treatment factors associated with children's PTSS after PICU discharge.MethodsA prospective longitudinal cohort study was conducted in two Australian tertiary referral PICUs. Children aged 2-16 y admitted to the PICU between June 2008 and January 2011 for >8 h and <28 d were eligible for participation. Biometric and clinical data were obtained from medical records. Parents reported their child's PTSS using the Trauma Symptom Checklist for Young Children at 1, 3, 6, and 12 months after discharge. Logistic regression was used to assess potential associations between medical treatment and PTSS.ResultsA total of 265 children and their parents participated in the study. In the 12-month period following PICU discharge, 24% of children exhibited clinically elevated PTSS. Median risk of death (Paediatric Index of Mortality 2 [PIM2]) score was significantly higher in the PTSS group (0.31 [IQR 0.14–1.09] v 0.67 [IQR 0.20–1.18]; p = 0.014). Intubation and PICU and hospital length of stay were also significantly associated with PTSS at 1 month, as were midazolam, propofol, and morphine. After controlling for gender, reason for admission, and PIM2 score, only midazolam was significantly and independently associated with PTSS and only at 1 month (adjusted odds ration (aOR) 3.63, 95% CI 1.18, 11.12, p = 0.024). No significant relationship was observed between the use of medications and PTSS after 1 month.ConclusionsElevated PTSS were evident in one quarter (24%) of children during the 12 months after PICU discharge. One month after discharge, elevated PTSS were most likely to occur in children who had received midazolam therapy.     

肥胖型PCOS患者的生物学特征和临床特征

多囊卵巢综合征（polycystic ovary syndrome,PCOS）是一种内分泌代谢紊乱综合征,临床表现高度异质性。肥胖是PCOS异质性临床表现之一,超过50%的PCOS患者超重或肥胖。肥胖型PCOS主要表现为高雄激素血症、中心型肥胖和糖脂代谢紊乱,非肥胖型PCOS主要表现为黄体生成激素（luteinizing hormone,LH）水平异常升高。尽管肥胖型和非肥胖型PCOS均存在内分泌代谢异常,然而肥胖可加重PCOS糖脂代谢紊乱;肥胖型PCOS还表现脂肪代谢的异常。综述肥胖型PCOS患者的临床特征、性激素水平、糖脂代谢特征,旨在为肥胖型和非肥胖型PCOS患者新的分型诊治提供参考。     

Mixed-mode versus paper surveys for patient-reported outcomes after critical illness: A randomised controlled trial

ObjectiveThe aim of the study was to determine the response rate to a mixed-mode survey using email compared with that to a paper survey in survivors of critical illness.DesignThis is a prospective randomised controlled trial.SettingThe study was conducted at a single-centre quaternary intensive care unit (ICU) in Adelaide, Australia.ParticipantsStudy participants were patients admitted to the ICU for ≥48 h and discharged from the hospital.InterventionsThe participants were randomised to receive a survey by paper (via mail) or via online (via email, or if a non-email user, via a letter with a website address). Patients who did not respond to the initial survey received a reminder paper survey after 14 days. The survey included quality of life (EuroQol-5D-5L), anxiety and depression (Hospital Anxiety and Depression Scale), and post-traumatic symptom (Impact of Event Scale-Revised) assessment.Main outcome measuresSurvey response rate, extent of survey completion, clinical outcomes at different time points after discharge, and survey cost analysis were the main outcome measures. Outcomes were stratified based on follow-up time after ICU discharge (3, 6, and 12 months).ResultsA total of 239 patients were randomised. The response rate was similar between the groups (mixed-mode: 78% [92/118 patients] vs. paper: 80% [97/121 patients], p = 0.751) and did not differ between time points of follow-up. Incomplete surveys were more prevalent in the paper group (10% vs 18%). The median EuroQol-5D-5L index value was 0.83 [0.71–0.92]. Depressive symptoms were reported by 25% of patients (46/187), anxiety symptoms were reported by 27% (50/187), and probable post-traumatic stress disorder was reported by 14% (25/184). Patient outcomes did not differ between the groups or time points of follow-up. The cost per reply was AU$ 16.60 (mixed-mode) vs AU$ 19.78 (paper).ConclusionThe response rate of a mixed-mode survey is similar to that of a paper survey and may provide modest cost savings.     

高强度聚焦超声联合甲氨蝶呤在瘢痕子宫妊娠行宫腔镜微创清宫术中的应用效果分析

目的 探究采用高强度聚焦超声(HIFU)联合甲氨蝶呤(MTX)在瘢痕子宫妊娠行宫腔镜微创清宫术中的应用效果。方法 选择2018年5月—2019年5月在本院接受宫腔镜治疗的108例瘢痕子宫妊娠患者,依据随机数字表法分为研究组与对照组,每组各54例。对照组使用HIFU预处理,研究组则使用HIFU联合MTX的方式预处理,处理后两组均行宫腔镜辅助微创清宫术。通过随访分析比较两组的治疗效果及妊娠结局。结果 研究组术后7 d血清β-HCG水平为(28 598.38±2 176.52)U/L,低于对照组的(32 423.13±2 734.65)U/L,差异有统计学意义(t=8.042,P<0.001);研究组血清β-HCG转阴时间、月经恢复时间、住院时间分别为(21.33±3.78)d、(28.21±3.83)d、(6.53±2.12)d,分别短于对照组的(26.72±4.83)d、(33.82±4.91)d、(9.53±2.67)d,差异具有统计学意义(t=6.458、6.620、6.466,P均<0.001)。两组均随访≥24个月,宫内妊娠、未孕、流产、再次瘢痕子宫妊娠、异位妊娠比较,差异无统计学意义(χ2=1.895,P>0.05);宫内妊娠中足月分娩与早产比较,差异无统计学意义(χ2=0.131,P>0.05),研究组并发症发生率为22.58%,低于对照组的37.50%,差异有统计学意义(χ2=5.296,P=0.021)。结论 在宫腔镜辅助微创清宫术治疗瘢痕子宫妊娠前使用HIFU联合MTX预处理的效果优于单一使用HIFU预处理,可明显缩短患者血清β-HCG转阴时间、月经恢复时间与住院时间,但对女性的妊娠结局无影响,妇产科临床治疗前可结合患者需求择取最合适的预处理方案。
