RESUMO

In this work, we explore the use of Piris natural orbital functionals (PNOFs) to calculate excited-state energies by coupling their reconstructed second-order reduced density matrix with the extended random-phase approximation (ERPA). We have named the general method PNOF-ERPA, and specific approaches are referred to as PNOF-ERPA0, PNOF-ERPA1, and PNOF-ERPA2, according to the way the excitation operator is built. The implementation has been tested in the first excited states of H2, HeH+, LiH, Li2, and N2 showing good results compared to the configuration interaction (CI) method. As expected, an increase in accuracy is observed on going from ERPA0 to ERPA1 and ERPA2. We also studied the effect of electron correlation included by PNOF5, PNOF7, and the recently proposed global NOF (GNOF) on the predicted excited states. PNOF5 appears to be good and may even provide better results in very small systems, but including more electron correlation becomes important as the system size increases, where GNOF achieves better results. Overall, the extension of PNOF to excited states has been successful, making it a promising method for further applications.

RESUMO

High motional resistance and incompatibility with post-CMOS fabrication due to thermal budget constraints are imperative issues associated with the back-end-of-line integration of lateral extensional vibrating micromechanical resonators. This paper presents piezoelectric ZnO-on-nickel resonators as a viable means for mitigating both of the issues. Lateral extensional mode resonators equipped with thin-film piezoelectric transducers can exhibit much lower motional impedances than their capacitive counterparts due to piezo-transducers' higher electromechanical coupling coefficients. Meanwhile, the employment of electroplated nickel as the structural material allows the process temperature to be kept lower than 300 °C, which is low enough for the post-CMOS resonator fabrication. In this work, various geometrical rectangular and square plates resonators are investigated. Moreover, parallel combination of several resonators into a mechanically coupled array was explored as a systematic approach to lower motional resistance from ~1 kΩs to 0.562 kΩs. Higher order modes were investigated for achieving higher resonance frequencies up to 1.57 GHz. Local annealing by Joule heating was also exploited for quality factor improvement after device fabrication by ~2× enhancement and breaking the record of MEMS electroplated nickel resonators in lowering insertion loss to ~10 dB.

RESUMO

Abstract The prevalence of depression varies from 1 to 17% in different geographic regions, and its incidence is 70% higher in women than men. Today, depression affects more than 300 million people worldwide, affecting twice as many women from adolescence to adulthood. In addition to this earlier onset, depression in women tends to be more severe. Cardiovascular disease and depression are chronic diseases that have a major impact on cardiovascular and all-cause morbidity and mortality, with evidence of a two-way relationship between them, in which depression is a predictor of cardiovascular disease and vice versa. In females, the degree of illness and prognosis are more severe when both diseases are present, than when diagnosed alone. In patients with acute or chronic cardiovascular disease, especially women, a systematic screening for depression should be considered as a preventive strategy of cardiovascular events, aiming to reduce the risk of future events. There are still no clinical studies designed to assess the impact of antidepressant treatment on cardiovascular outcomes in women.

RESUMO

OBJECTIVE: To characterize the clinical-epidemiological profile of multisystem inflammatory syndrome in children temporally associated with COVID-19 (MIS-C), and to identify factors associated with MIS-C deaths in Brazil, 2020. METHODS: This was a cross-sectional study, using national MIS-C monitoring data. Logistical regression was performed to estimate crude and adjusted odds ratios (OR). RESULTS: Median case (n=652) age was 5 years, 57.1% were male, 52.0% were of brown race/skin color and 6.4% died. Likelihood of death was greater among those who presented O2 saturation <95% (ORa=4.35 - 95%CI 1.69;11.20) and altered urea results (ORa=5.18 - 95%CI 1.91;14.04); likelihood of death was lower when red skin blotches were not present (ORa=0.23 - 95%CI 0.09;0.62), when anticoagulants were used (ORa=0.32 - 95%CI 0.12;0.89) and when immunoglobulins were used (ORa=0.38 - 95%CI 0.15;1.01). CONCLUSION: Fatality ratios were higher among cases that presented O2 saturation <95% and altered urea results. Fatality ratios were lower among those with red skin blotches, and those who used immunoglobulins and anticoagulants.

RESUMO

BACKGROUND: Maternal mortality rates in Brazil remain above the goals established by the United Nations Sustainable Development Goals. Heart disease is estimated to affect 4% of all pregnancies and remains by itself the main indirect obstetric cause of maternal death. In the last decades, a significant improvement in the prognosis of heart diseases has made pregnancy possible in women with heart disease and provided better maternal and fetal outcomes. OBJECTIVES: To establish a multicenter Brazilian Registry of pregnant women with heart disease; to study the causes of immediate and late maternal mortality; and to assess the prevalence of heart disease in the country's macro-regions. METHODS: This is an observational study, with retrospective and prospective stages, of the clinical and obstetric progression of pregnant women with heart disease. These women consecutively received care during pregnancy and will be followed up for up to a year after delivery at public and private hospitals with infrastructure for the execution of this project, a principal investigator, and approval by Ethics and Research Committees. RESULTS: Our results will be presented after data collection and statistical analysis, aiming to demonstrate immediate and late maternal mortality rates, as well as the prevalence of heart disease in the country and its cardiovascular and obstetric complications during pregnancy. CONCLUSIONS: REBECGA will be the Brazilian Registry of heart disease and pregnancy and it will contribute to planning preventive measures, raising financial resources for the improvement of high-risk prenatal care, and reducing immediate and late maternal mortality due to heart disease.

RESUMO

Latin America (LATAM) children offer special insight into Severe Acute Respiratory Syndrome Coronavirus 2 (SARS COV2) due to high-risk race/ethnicity, variability in medical resources, diverse socioeconomic background, and numerous involved organ systems. This multinational study of LATAM youth examined the distinguishing features of acute or late multisystem SARS COV2 with versus without cardiac involvement. A consecutive sample of youth 0-18 years old (N = 98;50% male) presenting with multisystem SARS COV2 to 32 centers in 10 Latin American countries participating in a pediatric cardiac multi-imaging society were grouped as with versus without cardiac involvement, defined as abnormal echocardiographic findings or arrhythmia. Collected clinical data were analyzed by Student's t-test or Fisher's exact test. Cardiac (N = 48, 50% male) versus no cardiac (N = 50, 50% male) were similar in age; weight; nonrespiratory symptoms; and medical history. The cardiac group had 1 death and symptoms including coronary artery dilation, ejection fraction <50%, pericardial effusion, peripheral edema, arrhythmia, and pulmonary artery thrombus. The cardiac group had higher risk of ICU admission (77% vs 54%, p = 0.02); invasive ventilation (23% vs 4%,p = 0.007); vasoactive infusions (27% vs 4%, p = 0.002); prominent respiratory symptoms (60% vs 36%, p < 0.03); abnormal chest imaging (69% vs 34%, p = 0.001); troponin (33% vs 12%, p = 0.01); alanine aminotransferase (33% vs 12%, p = 0.02); and thrombocytopenia (46% vs 22%, p = 0.02). Receiver operating curve analysis showed that abnormal laboratories had 94% sensitivity and 98% negative predictive value on the need for ICU interventions.Conclusion: In LATAM children with multisystem SARS COV2, cardiac involvement was prevalent. Cardiac involvement was more likely to require ICU interventions, certain abnormal labs, and respiratory involvement. What is Known: • SARS COV2 can be asymptomatic in children but in some cases can have serious multisystemic involvement. • Hispanic ethnicity is purportedly at high risk of SARS COV2 in nations where they are often disadvantaged minority populations. What is New: • Latin American children presenting with multisystem SARS COV2 frequently have cardiac involvement which was associated with ICU interventions; prominent respiratory symptoms; abnormal chest X-ray; elevated troponin, ALT, and thrombocytopenia. • Elevated troponin, ALT or thrombocytopenia had high sensitivity and negative predictive value on the need for intensive care interventions.

RESUMO

BACKGROUND: Trapezius Myalgia (TM) is characterized by shoulder pain and dysfunction. Kinesio Taping is commonly used in symptom management of TM. Biomechanical Taping (BMT), a novel intervention, may provide equally effective management. OBJECTIVES: This paper reports on the effectiveness of Biomechanical Taping compared with Kinesio Taping in improving shoulder pain, active range of motion (AROM), and function. METHODS: Two groups of participants with TM were recruited through simple random sampling of participants from nine call centers and purposively-sampled participants from one fast-food chain and one community based rehabilitation center in Manila, Philippines. Participants were randomly allocated to either Kinesio Taping or biomechanical taping group in a double-blind clinical trial. Irrespective of the type of taping, participants performed gentle passive stretching of upper trapezius for six times each held for 30 s on Days 1, 3, and 5. On Days 2 and 4, participants performed gentle passive stretch of upper trapezius three times a day. Pre- and post-intervention measures were taken of Visual Analogue Scale for pain intensity, AROM for shoulder movement, and Disability of Arm, Shoulder, and Hand for function. RESULTS: Of 68 participants, 62 had shoulder symptoms secondary to TM. Similar significant within group improvements were found for Visual Analogue Scale scores, and Disability of Arm, Shoulder and Hand for biomechanical taping and Kinesio Taping interventions when comparing between group results (p < 0.05). CONCLUSION: Biomechanical Taping appears to be as effective as Kinesio Taping in the short term in decreasing pain and improving function of individuals with TM. Both taping techniques did not restrict shoulder AROM of included participants. MESH TERMS: Athletic Tape, Myalgia, Pain Measurements, Shoulder Pain NON-MESH TERMS: Biomechanical Taping Technique.
