- BACKGROUND: Despite the increasing popularity of open water swimming worldwide, swimming-induced pulmonary edema (SIPE) is a poorly recognized condition lacking established diagnostic criteria.RESEARCH QUESTION: The aim of this study was to identify diagnostic criteria of SIPE during a large open water swimming event.STUDY DESIGN AND METHODS: In this cross-sectional study, 17,904 individuals swam 1,000, 1,500, or 3,000 m in cold open water during Sweden's largest open water swimming event in 2018 and 2019. Of 166 swimmers seeking medical attention for acute respiratory symptoms, 160 were included in the study. Medical history, symptoms, and clinical findings were collected. On-site lung ultrasound (LUS) was performed to verify pulmonary edema.RESULTS: Pulmonary edema was confirmed by LUS in 102 patients (64%); findings were unilateral in 11 (7%). Peripheral oxygen saturation was identified as a strong independent diagnostic test for pulmonary edema, with ≤ 95% as the suggested cut off based on receiver-operating characteristic curve analysis (area under the curve, 0.893; P < .0001). Crackles on lung auscultation, predominantly over the anterior chest, identified 88% of patients with edema. Peripheral oxygen saturation ≤ 95% or auscultation findings of crackles identified pulmonary edema with a sensitivity of 97% and a specificity of 86%. A specificity of 98% and a positive predictive value of 99% for LUS-verified pulmonary edema were reached if patients presented with both oxygen saturation ≤ 95% and auscultation of crackles.INTERPRETATION: We suggest a clinical algorithm for diagnosis of SIPE for swimmers with acute respiratory symptoms during swimming in cold open water. Novel features of focally distributed edema in the anterior parts of the lungs, sometimes unilateral, add to this unique dataset of an underreported condition.

- Despite solid evidence of an association between centralized body fatness and subsequent disease risk, little is known about the consequences of changes in body fat distribution. Recently it was shown that large hip circumference (HC), measured once, was protective against total and cardiovascular disease (CVD) mortality in women but that gain or loss in HC was unrelated to these outcomes. This study examines whether a 6-year change in waist circumference (WC) predicts mortality and CVD in the same study sample.

- Objective To examine height changes in middle-aged northern European women in relation to overall and cardiovascular mortality. Design Population-based cohort studies with longitudinally measured heights and register-based mortality. Setting Sweden and Denmark. Participants Population-based samples of 2406 Swedish and Danish women born on selected years in 1908-1952, recruited to baseline examinations at ages 30-60, and re-examined 10-13 years later. Main outcome measure Total and cardiovascular disease (CVD) specific mortality during 17-19 years of follow-up after last height measure. Results For each 1 cm height loss during 10-13 years, the HR (95% CI) for total mortality was 1.14 (1.05 to 1.23) in Swedish women and 1.21 (1.09 to 1.35) in Danish women, independent of key covariates. Low height and high leisure time physical activity at baseline were protective of height loss, independent of age. Considering total mortality, the HR for major height loss, defined as height loss greater than 2 cm, were 1.74 (1.32 to 2.29) in Swedish women and 1.80 (1.27 to 2.54) in Danish women. Pooled analyses indicated that height loss was monotonically associated with an increased mortality, confirming a significant effect above 2 cm height loss. For cause-specific mortality, major height loss was associated with a HR of 2.31 (1.09 to 4.87) for stroke mortality, 2.14 (1.47 to 3.12) for total CVD mortality and 1.71 (1.28 to 2.29) for mortality due to causes other than CVD. Conclusion Height loss is a marker for excess mortality in northern European women. Specifically the hazard of CVD mortality is increased in women with height loss during middle age, and the results suggest that the strongest cause-specific endpoint may be stroke mortality. The present findings suggest attention to height loss in early and mid-adulthood to identify women at high risk of CVD, and that regular physical activity may prevent early onset height loss.

- Objectives: Indication for invasive mechanical ventilation in COVID-19 pneumonia has been a major challenge. This study aimed to evaluate if lung ultrasound (LUS) can assist identification of requirement of invasive mechanical ventilation in moderate to severe COVID-19 pneumonia.Materials and Methods: Between April 23 and November 12, 2020, hospitalized patients with moderate to severe COVID-19 (oxygen demand >= 4 L/min) were included consecutively. Lung ultrasound was performed daily until invasive mechanical ventilation (IMV-group) or spontaneous recovery (non-IMV-group). Clinical parameters and lung ultrasound findings were compared between groups, at intubation (IMV-group) and highest oxygen demand (non-IMV-group). A reference group with oxygen demand <4 L/min was examined at hospital admission.Results: Altogether 72 patients were included: 50 study patients (IMV-group, n = 23; non-IMV-group, n = 27) and 22 reference patients. LUS-score correlated to oxygen demand (SpO(2)/FiO(2)-ratio) (r = 0.728; p < 0.0001) and was higher in the IMV-group compared to the non-IMV-group (20.0 versus 18.0; p = 0.026). Based on receiver operating characteristic analysis, a LUS-score of 19.5 was identified as cut-off for requirement of invasive mechanical ventilation (area under the curve 0.68; sensitivity 56%, specificity 74%). In 6 patients, LUS identified critical coexisting conditions. Respiratory rate and oxygenation index ((SpO(2)/FiO(2))/respiratory rate) >= 4.88 identified no requirement of invasive mechanical ventilation with a positive predictive value of 87% and negative predictive value of 100%.Conclusions: LUS-score had only a moderate diagnostic value for requirement of invasive mechanical ventilation in moderate to severe COVID-19. However, LUS proved valuable as complement to respiratory parameters in guidance of disease severity and identifying critical coexisting conditions.

- BACKGROUND: Swimming-induced pulmonary edema (SIPE) occasionally occurs during swimming in cold open water. While optimal treatment for SIPE is unknown, non-invasive positive pressure ventilation (NPPV) is an option for prehospital treatment.RESEARCH QUESTION: Is NPPV a feasible and safe prehospital treatment for SIPE, and which outcome measures reflect recovery after treatment?STUDY DESIGN AND METHODS: A prospective observational study was conducted at Vansbrosimningen, Sweden's largest open water swimming event, in 2017-2019. Swimmers diagnosed with SIPE and with peripheral oxygen saturation (SpO2) ≤95% and/or persistent respiratory symptoms were eligible for the study. NPPV was administered on-site as continuous positive airway pressure (CPAP) by facial mask or as positive expiratory pressure device (PEP-device). Discharge criteria were SpO2 >95% and clinical recovery. Four outcome measures were evaluated: SpO2, crackles on pulmonary auscultation, pulmonary edema on lung ultrasound (LUS) and patient-reported respiratory symptoms.RESULTS: Of 119 treated individuals, 94 received CPAP, 24 PEP-device and one required tracheal intubation. In total, 108 (91%) individuals were discharged after NPPV for median 10-20 minutes, 11 (9%) required hospital transfer. NPPV resulted in increased SpO2 from median 91% to 97% (p<0.0001) together with improvement of six patient-reported respiratory symptoms (median numerical rating scales 1-7 to 0-1; p<0.0001). No significant decrease in auscultation of crackles (93% vs 87%, p=0.508) or pulmonary edema on LUS (100% vs 97%, p=0.500) was seen during NPPV-treatment.INTERPRETATION: NPPV administered as CPAP or PEP-device proved feasible and safe as prehospital treatment for SIPE with a vast majority of patients discharged on-site. SpO2 and patient-reported respiratory symptoms reflected recovery after treatment, whereas pulmonary auscultation or LUS did not.

STUDY DESIGN AND METHODS: A prospective observational study was conducted at Vans-brosimningen, Sweden's largest open water swimming event, from 2017 through 2019. Swimmers with a diagnosis of SIPE and with peripheral oxygen saturation (SpO(2)) of # 95%, persistent respiratory symptoms, or both were eligible for the study. NPPV was administered on site as CPAP by facial mask or as positive expiratory pressure (PEP) by a PEP device. Discharge criteria were SpO(2) of > 95% and clinical recovery. Four outcome measures were evaluated: SpO(2), crackles on pulmonary auscultation, pulmonary edema on lung ultrasound (LUS), and patient-reported respiratory symptoms. RESULTS: Of 119 treated individuals, 94 received CPAP, 24 received treatment with a PEP device, and one required tracheal intubation. In total, 108 individuals (91%) were discharged after NPPV for a median of 10 to 20 min and 11 individuals (9%) required hospital transfer. NPPV resulted in increased SpO(2) from a median of 91% to 97% (P < .0001) together with improvement of six patient-reported respiratory symptoms (median numerical rating scales, 1-7 to 0-1; P < .0001). No significant decrease in auscultation of crackles (93% vs 87%; P = .508) or pulmonary edema on LUS (100% vs 97%; P = .500) was seen during NPPV treatment. INTERPRETATION: NPPV administered as CPAP or via a PEP device proved feasible and safe as prehospital treatment for SIPE with a vast majority of patients discharged on site. SpO2 and patient-reported respiratory symptoms reflected recovery after treatment, whereas pulmo-nary auscultation or LUS findings did not. CHEST 2022; 162(2):410-420
