[Ab] Resumo:BACKGROUND: Prediction of neonatal respiratory morbidity may be useful to plan delivery in complicated pregnancies. The limited predictive performance of the current diagnostic tests together with the risks of an invasive procedure restricts the use of fetal lung maturity assessment. OBJECTIVE: The objective of the study was to evaluate the performance of quantitative ultrasound texture analysis of the fetal lung (quantusFLM) to predict neonatal respiratory morbidity in preterm and early-term (<39.0 weeks) deliveries. STUDY DESIGN: This was a prospective multicenter study conducted in 20 centers worldwide. Fetal lung ultrasound images were obtained at 25.0-38.6 weeks of gestation within 48 hours of delivery, stored in Digital Imaging and Communication in Medicine format, and analyzed with quantusFLM. Physicians were blinded to the analysis. At delivery, perinatal outcomes and the occurrence of neonatal respiratory morbidity, defined as either respiratory distress syndrome or transient tachypnea of the newborn, were registered. The performance of the ultrasound texture analysis test to predict neonatal respiratory morbidity was evaluated. RESULTS: A total of 883 images were collected, but 17.3% were discarded because of poor image quality or exclusion criteria, leaving 730 observations for the final analysis. The prevalence of neonatal respiratory morbidity was 13.8% (101 of 730). The quantusFLM predicted neonatal respiratory morbidity with a sensitivity, specificity, positive and negative predictive values of 74.3% (75 of 101), 88.6% (557 of 629), 51.0% (75 of 147), and 95.5% (557 of 583), respectively. Accuracy was 86.5% (632 of 730) and positive and negative likelihood ratios were 6.5 and 0.3, respectively. CONCLUSION: The quantusFLM predicted neonatal respiratory morbidity with an accuracy similar to that previously reported for other tests with the advantage of being a noninvasive technique.

[Ab] Resumo:We prospectively evaluated afebrile patients admitted to an emergency department (ED), with suspected infection and only tachycardia or tachypnea.The white blood cell count (WBC) was obtained, and patients were considered septic if leukocyte count was >12,000 µL-1 or <4000 µL-1 or with >10% of band forms. Clinical data were collected to examine whether sepsis could be predicted.Seventy patients were included and 37 (52.86%) met sepsis criteria. Self-measured fever showed an odds ratio (OR) of 5.936 (CI95% 1.450-24.295; P = 0.0133) and increased pulse pressure (PP) showed an OR of 1.405 (CI95% 1.004-1.964; P = 0.0471) on multivariate analysis. When vital signs were included in multivariate analysis, the heart rate showed an OR of 2.112 (CI95% 1.400-3.188; P = 0.0004). Self-measured fever and mean arterial pressure <70 mm Hg had high positive likelihood ratios (3.86 and 2.08, respectively). The nomogram for self-measured fever showed an increase of sepsis chance from 53% (pretest) to approximately 80% (post-test).The recognition of self-measured fever, increased PP, and the intensity of heart rate response may improve sepsis recognition in afebrile patients with tachycardia or tachypnea. These results are important for medical assessment of sepsis in remote areas, crowded and low-resourced EDs, and low-income countries, where WBC may not be readily available.

[Ab] Resumo:Acute kerosene poisoning is a preventable health problem in children perceived mainly in developing countries. It influences socioeconomic and cultural status of country due to its contribution in morbidity and mortality. As kerosene is widely used as household energy source in India at rural areas as well as urban, it accounts for significant number of poisoning cases mainly accidental in manner. As there are only handful studies from India on kerosene poisoning in children, we planned this study to evaluate incidence of kerosene poisoning in Western Indian population and its clinico-epidemiotoxicological profile. In this retrospective cross-sectional study, we collected data of all the cases of kerosene poisoning diagnosed during five years from 2009 to 2013 at Shri Krishna hospital situated at Karamsad, Gujarat state of Western India. We observed among total 42 cases, all victims were under 3 years of age. Evening in summer months, rural areas, storage of kerosene in household containers, inadequate parental supervision and door-to-hospitalization period emerged as most serious associated factors. Fever, cough, vomiting, tachypnoea and leucocytosis were commonest manifestations while pneumonia was the most common complication. Signs of central nervous system involvement, leucocytosis and vomiting were significantly correlated with pneumonia. Deaths occurred due to pneumonia. Early diagnosis and treatment of pneumonia may reduce mortality and recommendations are made to reduce the incidence of kerosene poisoning.

[Ab] Resumo:BACKGROUND: Chronic lung diseases are increasingly recognized complications of vertically-acquired HIV among adolescents in sub-Saharan Africa and may manifest with hypoxia or tachypnea. We sought to determine the prevalence of and risk factors for hypoxia and tachypnea among adolescents with vertically-acquired HIV in Nairobi, Kenya. METHODS: We performed a cross-sectional analysis of 258 adolescents with vertically-acquired HIV who were initiating care at the Coptic Hope Center for Infectious Diseases. Adolescents with documented pneumonia were excluded. Hypoxia was defined as resting oxygen saturation ≤92%, and tachypnea was based on the 99th percentile of age-appropriate respiratory rates. Logistic regression models adjusted for demographics, and HIV severity estimated odds ratios for risk of hypoxia and tachypnea associated with potential risk factors. RESULTS: Overall, 11% of adolescents had hypoxia and 55% had tachypnea. Advanced HIV [adjusted odds ratio (aOR): 2.41] and low CD4 (aOR: 1.74) were associated with greater hypoxia risk, but confidence intervals (CIs) were wide and included the null (95% CI: 0.93-6.23 and 0.69-4.39, respectively). Low CD4 (aOR: 2.45, 95% CI: 1.39-4.32), current antiretroviral therapy use (aOR: 0.48, 95% CI: 0.27-0.86) and stunted growth (aOR: 3.46, 95% CI: 1.94-6.18) were associated with altered tachypnea risk. CONCLUSIONS: Hypoxia and tachypnea are common among adolescents with vertically-acquired HIV. There was a suggestion that advanced HIV and low CD4 were associated with greater hypoxia risk. Low CD4, lack of antiretroviral therapy use and stunted growth are risk factors for tachypnea. Our findings highlight the chronic lung disease burden in this population and may inform diagnostic algorithms.

[Ab] Resumo:OBJECTIVE: The purpose of this study is to investigate the effect of gadoxetate disodium administration on arterial phase respiratory waveforms. SUBJECTS AND METHODS: From 2013 to 2015, 107 subjects undergoing liver MRI with either gadoxetate disodium (10 mL diluted 1:1 with saline; injection rate, 2 mL/s; n = 40) or gadobenate dimeglumine (0.2 mL/kg; maximum, 20 mL; injection rate, 2 mL/s; n = 67) were enrolled. Respiratory waveforms obtained during unenhanced and dynamic contrast-enhanced phases were filtered by a physicist, who was blinded to contrast agent and imaging phase, to eliminate electronic and cardiac noise using fast Fourier transformation. The average root-mean-square difference of two intrasubject control phases (unenhanced and late dynamic) was termed D1, and the root-mean-square deviation of the arterial phase referent to the control record mean was termed D2. D1, D2, and their difference were compared across agents with the Mann-Whitney U test. Bland-Altman plots were generated for D1 and D2 values. RESULTS: D1 values were similar for both agents (mean [± SD], 232 ± 203 for gadoxetate vs 201 ± 230 for gadobenate; p = 0.48), indicating similar intercohort baseline breath-holding capability. D2 was greater and more variable for the gadoxetate cohort (438 ± 381) than for the gadobenate cohort (167 ± 167; p < 0.001), indicating larger and more unpredictable respiratory waveform deviations isolated to the arterial phase (subject-level rate, 48% [19/40] for gadoxetate vs 1% [1/67] for gadobenate; p < 0.001). Aberrant respiratory waveform peaks in the arterial phase were usually associated with transient tachypnea (mean maximum arterial phase respiratory rate for the gadoxetate cohort, 27 breaths/min; range, 11-40 breaths/min). CONCLUSION: Fixed-dose gadoxetate disodium (10 mL; 1:1 dilution with 10 mL of saline; injection rate, 2 mL/s) transiently reduces breath-holding capacity during the arterial phase and is accompanied by brief transient tachypnea.

[Ab] Resumo:BACKGROUND: Thyroid storm, an endocrine emergency, remains a diagnostic and therapeutic challenge. It is recognized to develop as a result of several factors, including infection, surgery, acute illness, and rarely, trauma. Recognition of thyroid storm in a trauma patient is difficult because the emergency physician usually focuses on managing more obvious injuries. OBJECTIVE OF THE REVIEW: We present a case of trauma-related thyroid storm and review the previous literature on posttraumatic thyroid storm to delineate risk factors of the disease. The case occurred in a 32-year-old man after a motorcycle accident. DISCUSSION: Careful investigation of patient history and risk factors of trauma-related thyroid storms and utilization of the scoring system may facilitate early diagnosis. Traumatically induced thyroid storm usually responds to medical treatment developed for hyperthyroidism. Surgical intervention may be needed for patients who failed medical treatment or those with direct thyroid gland injuries. The outcome is usually fair under appropriate management. CONCLUSION: We present a case of trauma-related thyroid storm to illustrate the diagnostic and therapeutic approach with a summary of the previous literature. Emergency physicians should be aware of the clinical presentation and risk factors of patients with trauma-related thyroid storm to reduce the rate of misdiagnosis and prevent catastrophic outcomes.

[Ab] Resumo:INTRODUCTION: The change from risk-factor-based to nearly comprehensive screening of gestational diabetes (GDM) identifies more but milder cases of the disease. The main aim of this study was to evaluate the effect of this screening policy change on neonatal outcomes and care. MATERIAL AND METHODS: A population-based register study in Finland. GDM cases during risk-factor-based (year 2006, n = 5179) and comprehensive (2010, n = 6679) screenings were identified through the Medical Birth Register. All singletons without maternal GDM or prepregnancy diabetes served as controls (n = 51 746 and n = 52 386, respectively). The main outcomes were macrosomia, neonatal hypoglycemia and the need for care in a neonatal ward. RESULTS: In the GDM group, the mean birthweight decreased between the study years from 3660 g to 3595 g and the prevalence of macrosomia from 5.6 to 4.1% even after adjustment for maternal age, parity and prepregnancy body mass index. The adjusted mean difference in birthweight between GDM and control newborns decreased from 70 to 22 g between the study years. The prevalence of neonatal hypoglycemia increased from 18.0 to 22.1% in the GDM group. However, neonatal hypoglycemia was more often treated without care in a neonatal ward. The proportion of infants treated on a neonatal ward decreased in both the GDM and control groups between the study years. CONCLUSIONS: In newborns, comprehensive GDM screening led to decreased mean birthweight and macrosomia rates, but the prevalence of neonatal hypoglycemia increased. This places substantial demands for delivery hospitals and healthcare resources.

[Ab] Resumo:During exercise, tidal volume initially contributes to ventilatory responses more than respiratory frequency, and respiratory frequency then increases rapidly while tidal volume stabilizes. Dyspnea intensity is also known to increase in a threshold-like manner. We tested the possibility that the threshold of tachypneic breathing is equal to that of dyspnea perception during cycle ergometer exercise (n = 27). Dyspnea intensity was scored by a visual analog scale. Thresholds were expressed as values of pulmonary O uptake at each breakpoint. Dyspnea intensity and respiratory frequency started increasing rapidly once the intensity of stimuli exceeded a threshold level. The thresholds for dyspnea intensity and for occurrence of tachypnea were significantly correlated. An intraclass correlation coefficient of 0.71 and narrow limits of agreement on the Bland-Altman plot indicated a good agreement between these thresholds. These results suggest that the start of tachypneic breathing coincides with the threshold for dyspnea intensity during cycle ergometer exercise.
