Effects of obesity on weight-bearing versus weight-supported exercise testing in patients with COPD.

BACKGROUND AND OBJECTIVE: Obesity is associated with increased dyspnoea and reduced health status in patients with chronic obstructive pulmonary disease (COPD). Studies on the effects of obesity on exercise capacity showed divergent results. The objective of this study is to investigate the impact of obesity on weight-bearing versus weight-supported exercise tolerance in obese and normal weight patients, matched for age, gender and degree of airflow limitation. METHODS: Retrospective analyses of data obtained during pre-pulmonary rehabilitation assessment in 108 obese COPD patients (OB) (age: 61.2 ± 5.3y, FEV1 : 43.2 ± 7.4%, BMI: 34.1 ± 3.9 kg/m(2) ,) and 108 age and FEV1 -matched normal weight COPD patients (NW) (age: 61.7 ± 3.6y, FEV1 : 41.5 ± 8.4%, BMI: 22.9 ± 1.2 kg/m(2) ,). Cardiopulmonary exercise test (CPET) and 6 min walk test (6MWT) were performed, Borg scores for dyspnoea and leg fatigue were recorded, before and after the tests. RESULTS: Six-minute walk distance differed between OB (398 ± 107 m) and NW patients (446 ± 109 m, P < 0.05), while peak cycling exercise load was comparable (OB: 75 ± 29 W, NW: 70 ± 25 W, ns). Dyspnoea (OB 3.2 ± 2.0 vs NW 3.1 ± 1.7, ns) and leg fatigue (OB 2.4 ± 2.3 vs NW 1.9 ± 1.7, ns) were not significantly different in OB compared with NW after 6MWT, or after CPET (dyspnoea: OB 5.1 ± 2.4 vs NW 5.4 ± 2.2, ns; leg fatigue: OB 4.0 ± 2.3 vs NW 4.0 ± 2.7, ns). CONCLUSION: In contrast to weight-supported exercise, obesity has a negative impact on weight-bearing exercise capacity, despite comparable exercise-related symptoms. The results of this study enhance the understanding of the impact of obesity on physical performance in COPD.

Deferring diagnostic evaluation of suspected deep vein thrombosis using direct oral anticoagulant or low-molecular-weight heparin as a single dose anticoagulant: A prospective real-world study in a regionwide care pathway.

BACKGROUND: Patients with suspected deep vein thrombosis (DVT) are typically referred to the emergency department for immediate evaluation. To enhance efficiency, our hospital implemented a regional, general practitioner (GP)-driven DVT care pathway, deferring diagnostic evaluation to a scheduled outpatient DVT clinic appointment the following day. Patients receive a single dose anticoagulant from their GP to prevent thrombosis progression while awaiting diagnostic workup. This prospective study aimed to evaluate the safety and patient preferences regarding the DVT care pathway and the type of single dose anticoagulant (low-molecular-weight heparin (LMWH) vs. direct oral anticoagulant (DOAC)). METHODS: Patients enrolled in the DVT care pathway between June 2021 and July 2023 were eligible. Until July 2022, LMWH was administered, and thereafter, the protocol recommended DOAC as the single dose anticoagulant. Patients completed questionnaires, incorporating patient-reported outcome and experience measures (PROMs/PREMs), during their DVT clinic visit and after five days. The primary endpoint was bleeding events within 72 h of receiving the single dose anticoagulant. RESULTS: Of 460 included patients, 229 received LMWH and 231 received DOAC as the single dose anticoagulant. DVT was confirmed in 24.8 % of patients. No major or clinically relevant non-major bleeding were reported. LMWH was associated with more minor bleedings (22.3 % vs. DOAC 13.4 %), primarily attributed to injection site hematomas. Patients reported high satisfaction with the DVT care pathway (96.5 %) and generally preferred DOAC over LMWH. CONCLUSION: Deferring diagnostic evaluation for DVT using a single dose of either LMWH or DOAC in a real-world population is deemed safe. Considering practical advantages, patient preferences, and fewer skin hematomas, we favor DOACs as the single dose anticoagulant in this care pathway.

Deferring diagnostic evaluation for suspected deep venous thrombosis using a single dose of anticoagulant: Real-world data from a regionwide care pathway.

BACKGROUND: Patients with suspected deep venous thrombosis (DVT) are typically referred to the emergency department (ED) for immediate evaluation. However, this often contributes to ED overcrowding and necessitates round-the-clock sonographic examinations. Therefore, we implemented a regionwide care pathway for deferring diagnostic workup of suspected DVT until the following day. Patients receive a single anticoagulant dose from their general practitioner (GP) to prevent progression of DVT in the interval between referral and diagnostic evaluation. The next day, patients undergo comprehensive evaluation at our outpatient DVT clinic, including venous ultrasound. This retrospective study aims to provide real-world data on the safety of this care pathway regarding the occurrence of bleeding complications and pulmonary embolism (PE). METHODS: We included all GP-referred patients with suspected DVT in 2018 and 2019. Patients with absolute contraindications to deferred evaluation or anticoagulation were excluded. The primary endpoint was the occurrence of bleeding complications. Secondary endpoints included PE events and all-cause mortality within seven days following DVT evaluation. RESULTS: Among 1,024 included patients, DVT was confirmed in 238 patients (23.2%) and superficial thrombophlebitis in 98 patients (9.6%). No bleeding events were recorded in patients in whom DVT was ruled out. PE was confirmed in eight patients on the same day as DVT evaluation (0.8%, 95%CI 0.4-1.6) and in six patients within seven days following DVT evaluation (0.6%, 0.2-1.3%). No deaths occurred during this timeframe. CONCLUSION: This real-world study observed a very low incidence of bleeding complications and PE events, indicating that this care pathway of deferred DVT workup is safe and may offer a more streamlined diagnostic approach for patients with suspected DVT.

Should the law on anonymity of organ donation be changed? The perception of liver transplant recipients.

BACKGROUND: Belgian politicians submitted a proposal to rescind the law on anonymity of organ donation and transplantation and facilitate contact between donor families and recipients. It remains uncertain if recipients support this proposal. METHODOLOGY: One liver transplant patient organization (n = 176/249) answered and provided comments on two questions: (i) how satisfied are you with the current principle of anonymity of the identity of the donor and (ii) the law about anonymity should be changed to allow the donor family and the patient to meet. RESULTS: Seventy percent were satisfied/very satisfied with the present law, because of anxiety for emotional involvement or feeling obliged to do something in return, feelings of guilt, and out of mutual respect. Nineteen percent was dissatisfied/very dissatisfied and want to obtain some information about the donor, and directly express their gratitude. Forty-two percent disagreed with a change, because of anxiety for manipulation, feelings of guilt, respect for the privacy, and worry about the donor having a different background. Thirty-six percent wanted to change the law out of curiosity, to express their gratitude, or to facilitate their coping process. DISCUSSION: Prudence to change the law is warranted, as only a minority of patients are in favor of rescinding the anonymity.

Exercise-induced oxygen desaturation in COPD patients without resting hypoxemia.

Exercise-induced oxygen desaturation (EID) is associated with increased risk of mortality in chronic obstructive pulmonary disease (COPD). Several screening tests have been proposed to predict EID, including FEV1, DLCO and baseline-SpO2. We aimed to validate a proposed cut-off of baseline-SpO2 ≤95% as simple screening procedure to predict EID during six-minute walk test (6MWT). In addition, we studied the prevalence and characteristics of patients exhibited EID to SpO2nadir ≤88%. 402 non-hypoxemic COPD patients performed 6MWT. Sensitivity and specificity of baseline SpO2 ≤95% as a cut-off to predict EID and determinants of EID were investigated. 158 patients (39%) exhibited EID. The sensitivity of baseline-SpO2 ≤95% to predict EID was 81.0%, specificity 49.2%, positive and negative predictive values were 50.8% and 80.0%, respectively. In a multivariate model, DLCO <50%, FEV1 <45%, PaO2 <10kPa, baseline-SpO2 <95%, and female sex were the strongest determinants of EID. Baseline oxygen saturation solely is inaccurate to predict EID. A combination of clinical characteristics (DLCO, FEV1, PaO2, baseline-SpO2, sex) increases the odds for EID in COPD.

Prognostic factors for the success of endometrial ablation in the treatment of menorrhagia with special reference to previous cesarean section.

OBJECTIVE: To assess whether, among other prognostic factors, a history of Cesarean section is associated with endometrial ablation failure in the treatment of menorrhagia. Study design We compared women who had failed ablation to women who had successful ablation for menorrhagia in a case-control study. Failed ablation was defined as the need for hysterectomy due to persistent heavy menstrual bleeding after ablation. Successful ablation was defined as an ablation for menorrhagia not needing hysterectomy and the woman being satisfied with the result. Both cases and controls were identified from the surgery registration in the Máxima Medical Center between January 1999 and January 2009. Cases were women that had an endometrial ablation and a hysterectomy, whereas controls only had an endometrial ablation. From the medical files we collected for each patient clinical history, including the presence of a previous Cesarean section, baseline characteristics at the moment of initial ablation, data of the ablation technique and follow-up status. We used univariable and multivariable logistic regression to estimate the risk of failure of endometrial ablation. RESULTS: We compared 76 cases to 76 controls. Among the cases, 12 women had had a previous Cesarean section versus 15 in the control group (15.8% versus 19.7%; odds ratio (OR) 0.76; 95% CI 0.3-1.8). Factors predictive for failure of ablation were dysmenorrhea (OR 3.0; 95% CI 1.5-6.1), having a submucous myoma (OR 3.2; 95% CI 1.5-6.8) and uterine depth (per cm OR 1.3; 95% CI 1.0-1.6). Presence of intermenstrual bleeding, sterilization and age were not associated with failure of ablation. CONCLUSION: A previous Cesarean delivery is not associated with an increased risk of failure of endometrial ablation, but dysmenorrhea, a submucous myoma and longer uterine depth are. This should be incorporated in the counseling of women considering endometrial ablation.
