Sleep Apnea in a Sample of Patients with Treatment Resistant Depression Referred for Electroconvulsive Therapy

Objective Symptoms of sleep apnea (SA) often overlap with symptoms of depression. Without extensive exploration of a patient’s history it is possible that SA could complicate depression leading to treatment resistant depression (TRD) which is then referred for electroconvulsive therapy (ECT). To date no study has reported on prevalence of SA within this population. Materials and Methods We conducted a retrospective chart review of patients referred for ECT for TRD from 2008 to 2011 (N=118) at the Central Arkansas Veteran’s Healthcare System. Patients were placed into categories of known SA (diagnosed with polysomnography and recorded on chart), high risk SA (suspected SA documented in the chart by a physician), or unknown/low risk SA (negative polysmonography). Results Average age was 54.5±12 years. Average body mass index (BMI) was 30.3±7.3 kg/m2. 36% had either known SA (27%) or were at high risk of having SA (9%). Those with known SA were more likely to have hypertension (9.4 CI 3-29.5), BMI≥30 kg/m2 (5.4 CI 2.2-13.5), and hyperlipidemia (4.2 CI 1.6-11.4). Known SA was not significantly associated with diabetes mellitus (2.2 CI 0.8-5.6), complaints of pain (2.4 CI 0.9-5.9), or headache (1.5 CI 0.6-3.8). Conclusion A diagnosis of SA should be considered in patients referred for ECT for TRD. BMI≥30 kg/m2, presence of hypertension, and hyperlipidemia are more likely in patients with SA and should raise suspicion of the disorder in patients within this population

Non-sleepy obstructive sleep apnoea: to treat or not to treat?

Non-sleepy obstructive sleep apnoea (OSA) is thought to have a prevalence of around 20-25% in industrialised countries. However, the question of whether it should be routinely treated or not is controversial. This review collates the results from recent randomised controlled trials addressing OSA and examines whether treating the condition leads to improvements in quality of life and reduced cardiometabolic dysfunction, comorbidities generally attributed to untreated obstructive sleep apnoea/hypopnoea syndrome

Soluble urokinase-type plasminogen activator receptor is a novel biomarker predicting acute exacerbation in COPD

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory condition, and progresses with acute exacerbations. (AE). During AE, levels of acute phase reactants such as C-reactive protein (CRP) and inflammatory cells in the circulation increase. Soluble urokinase-type plasminogen activator receptor (suPAR) levels increase in acute viral and bacterial infections and in diseases involving chronic inflammation. The purpose of this study was to investigate the effectiveness of suPAR in predicting diagnosis of AE of COPD (AE-COPD) and response to treatment. METHODS: The study population consisted of 43 patients diagnosed with AE-COPD and 30 healthy controls. suPAR, CRP, and fibrinogen levels were measured on the first day of hospitalization and on the seventh day of treatment. RESULTS: We found that fibrinogen (P<0.001), CRP (P<0.001), and suPAR (P<0.001) were significantly higher in patients with AE-COPD than in healthy controls. Fibrinogen (P<0.001), CRP (P=0.001), and suPAR (P<0.001) were significantly decreased by the seventh day of treatment. However, the area under receiver operator characteristic curve showed that suPAR is superior to CRP and fibrinogen in distinguishing AE-COPD. There was a correlation between fibrinogen, CRP, and suPAR. However, only fibrinogen was a powerful predictor of suPAR in multiple linear regression. In multiple logistic regression, only suPAR and fibrinogen were strong predictors of AE-COPD (P=0.002 and P=0.014, respectively). Serum suPAR was negatively correlated with forced expiratory volume in 1 second (r=−478, P=0.001). CONCLUSION: suPAR is a marker of acute inflammation. It is well correlated with such inflammation markers as CRP and fibrinogen. suPAR can be used as a predictor of AE-COPD and in monitoring response to treatment

Effect of CPAP on New Endothelial Dysfunction Marker, Endocan, in People With Obstructive Sleep Apnea.

Obstructive sleep apnea (OSA) is associated with increased cardiovascular (CV) morbidity and mortality. Endocan is a surrogate endothelial dysfunction marker that may be associated with CV risk factors. In this study, we tested whether serum endocan is a biomarker for OSA. Serum endocan levels were measured at baseline in 40 patients with OSA and 40 healthy controls and after 3 months of continuous positive airway pressure (CPAP) treatment in the patients with OSA. All participants were evaluated by full polysomnography. Flow-mediated dilatation (FMD) and carotid intima media thickness (cIMT) were measured in all participants. Endocan levels were significantly higher in patients with OSA than in healthy controls. After adjusting confounders, endocan was a good predictor of OSA. Endocan levels correlated with OSA severity (measured by the apnea-hypopnea index [AHI]). After 3 months of CPAP treatment, endocan levels significantly decreased. Endocan levels were significantly and independently correlated with cIMT and FMD after multiple adjustments. The cIMT and FMD also had significant and independent correlation with AHI. Endocan might be a useful marker for the predisposition of patients with OSA to premature vascular disease

The safety of major gynaecologic cancer surgery without routine preoperative COVID-19 testing in the COVID-19 era: a multicentre, retrospective, case-control study

Our goal was to address the safety of major gynaecologic cancer surgery without routine preoperative COVID-19 testing in the COVID-19 era. The databases of seven gynaecologic cancer centres were searched in order to identify all consecutive gynaecologic cancer patients undergoing major surgery between March 11, 2020 and May 15, 2020 for this retrospective, case-control study. The case group consisted of patients with histopathologically confirmed gynaecologic cancers, and each case was matched with two counterparts who had undergone primary surgery before the COVID-19 pandemic. The case and the control groups were compared in terms of length of hospital stay, admission to the intensive care unit (ICU), intraoperative and postoperative complications. During the study period, 154 women with gynaecologic cancer undergoing major surgery were identified. Although the case group had more co-morbidities compared to the control group (103/154 vs. 178/308, respectively; p = .04), the median length of hospital stays, the rate of ICU admission, intraoperative complication rates and postoperative complication rates were similar in the two groups. Gynaecologic cancer surgery may be performed safely in the COVID-19 era with similar rates of ICU admission, intraoperative and postoperative complications compared to the patients operated before the COVID-19 pandemic.IMPACT STATEMENT What is already known on this subject? Many societies have announced their guidelines about the surgical management of gynaecologic cancer patients during the COVID-19 pandemic. However, most of them are not evidence-based and mostly on expert opinions. What do the results of this study add? The main findings of this retrospective, case-control study indicate that the short-term (30 day) outcomes of gynaecologic cancer patients undergoing major surgery in the COVID-19 era are similar to those who had been operated before the COVID-19 pandemic. The length of hospital stays, the rates of admission to the ICU, intraoperative and postoperative complications were comparable between women undergoing major gynaecologic cancer surgery in the COVID-19 era and the women who had been operated before the pandemic. What are the implications of these findings for clinical practice and/or further research? We can suggest that definitive surgery may be performed for gynaecologic cancer patients in the COVID-19 era if the resources permit and appropriate precautions such as social distancing, isolation and the use of personal protective equipment are taken
