RESUMO

BACKGROUND: Hypoxic ischemic encephalopathy (HIE) is a significant cause of mortality and short- and long-term morbidities. Therapeutic hypothermia (TH) has been shown to be the standard care for HIE of infants ≥36 weeks gestational age (GA), as it has been demonstrated to reduce the rates of mortality, and adverse neurodevelopmental outcomes. This study aims to determine the incidence of HIE in our country, to assess the TH management in infants with HIE, and present short-term outcomes of these infants. METHODS: The Turkish Hypoxic Ischemic Encephalopathy Online Registry database was established for this multicenter, prospective, observational, nationally-based cohort study to evaluate the data of infants born at ≥34 weeks GA who displayed evidence of neonatal encephalopathy (NE) between March, 2020 and April 2022. RESULTS: The incidence of HIE among infants born at ≥36 weeks GA (n = 965) was 2.13 per 1000 live births (517:242440), and accounting for 1.55% (965:62062) of all neonatal intensive care unit admissions. The rates of mild, moderate and severe HIE were 25.5% (n = 246), 58.9% (n = 568), and 15.6% (n = 151), respectively. Infants with severe HIE had higher rates of abnormal magnetic resonance imaging (MRI) findings, and mortality (p<0.001). No significant difference in mortality and abnormal MRI results was found according to the time of TH initiation (<3 h, 3-6 h and >6 h) (p>0.05). TH was administered to 85 (34.5%) infants with mild HIE, and of those born of 34-35 weeks of GA, 67.4% (n = 31) received TH. A total of 58 (6%) deaths were reported with a higher mortality rate in infants born at 34-35 weeks of GA (OR 3.941, 95% Cl 1.446-10.7422, p = 0.007). CONCLUSION: The incidence of HIE remained similar over time with a reduction in mortality rate. The timing of TH initiation, whether <3 or 3-6 h, did not result in lower occurrences of brain lesions on MRI or mortality. An increasing number of infants with mild HIE and late preterm infants with HIE are receiving TH; however, the indications for TH require further clarification. Longer follow-up studies are necessary for this vulnerable population.

RESUMO

Introduction: Data on the effectiveness of hydrolyzed infant formula containing both pre- and probiotics (synbiotic formula) on the growth of infants is still scarce. This retrospective study was designed to evaluate the effect of a partially hydrolyzed synbiotic formula on growth parameters and the possible occurrence of major gastrointestinal adverse events or morbidities in infants born via cesarean section (C-section) delivery. Methods: C-section-delivered term and late preterm infants who received either partially hydrolyzed synbiotic formula, standard formula, or maternal milk and followed at seven different hospitals from five different regions of Turkey, during a 1-year period with a minimum follow-up duration of 3 months were evaluated retrospectively. All the included infants were evaluated for their growth patterns and any kind of morbidity such as diarrhea, constipation, vomiting, infection, or history of hospitalization. Results: A total of 198 infants (73 in the human milk group, 61 in the standard formula group, and 64 in the partially hydrolyzed synbiotic formula group) reached the final analysis. The groups were similar regarding their demographic and perinatal characteristics. No difference was observed between the three groups regarding gastrointestinal major side effects. Growth velocities of the infants in the human milk and partially hydrolyzed synbiotic formula groups during the first month of life were similar whereas the weight gain of infants in the standard formula group was significantly less than these two groups (p < 0.001). Growth velocities were similar among the three groups between 1st and 3rd months of age. Discussion: A partially hydrolyzed synbiotic formula provided better weight gain in late-preterm and term infants who were delivered via C-section delivery compared to the standard formula during the first month of life. This weight gain was similar to the infants receiving exclusively human milk. This difference was not observed in length and head circumference gain. No difference was observed in any of the parameters during the 1st-3rd months of age. Specially formulated partially hydrolyzed synbiotic formulas may reverse at least some of the negative impacts of C-section delivery on the infant and help to provide better growth, especially during the early periods of life.

RESUMO

PURPOSE: The aim of this study is to compare the speech fluency performance of non-fluent participants namely people with stuttering (PWS), people with cluttering (PWC) and people with cluttering and stuttering (PWCS) with a fluent control group using the Turkish version of Predictive Cluttering Inventory-revised (TR-PCI-r). METHODS: The study recruited non-fluent individuals (n = 60) and fluent controls (n = 60) between the ages of 6 and 55. The non-fluent group was perceptually evaluated by two speech and language pathologists (SLP). The speaking, reading and retelling samples were collected from 18 PWC, 17 PWCS, 25 PWS and 60 controls. The scores of each factor were compared. Age and gender differences were analyzed. Validity and reliability were calculated. RESULTS: The agreement between two SLPs was found to be at the barely acceptable level (κ = 0.378). PWC and PWCS produced parallel outcomes in the speech motor area. In every other domain and in total scores, PWC were different from PWCS, PWS, and the controls. There was a variation in the total scores obtained by the children and adolescents in the PWS and between males and females in the controls. Except for three items (namely items 8, 22, 27), TR-PCI-r met the content validity criterion. Furthermore, TR-PCI-r was found to be a reliable tool as shown by ɑ> 0.70 and ICC values of between 0.75 and 0.90. CONCLUSION: The scores from TR-PCI-r indicated that, speech motor characteristics of PWC and PWCS were similar. Other features assessed by the tool seemed to distinguish PWC from PWCS, PWS and controls.

RESUMO

AIMS: We aim to assess the theoretical impact of the atrial flow regulator (AFR) on survival in heart failure. METHODS AND RESULTS: The prospective, multicentre, open-label, non-randomised PRELIEVE study (NCT03030274) assessed the safety and efficacy of the Occlutech AFR device in patients with symptomatic heart failure with reduced ejection fraction (HFrEF) (left ventricular ejection fraction (LVEF) ≥ 15% and <40%) or heart failure with preserved ejection fraction (HFpEF) (LVEF ≥40% and <70%) and elevated PCWP (≥15 mmHg at rest or ≥25 mmHg during exercise). In this analysis, after the first 60 patients completed 12 months of follow-up, the theoretical impact of AFR implantation on survival was assessed by comparing the observed mortality rate with the median predicted probability for one-year mortality. Each subject's risk of mortality was predicted from individual baseline data using the Meta-Analysis Global Group in Chronic HF (MAGGIC) prognostic model. A total of 87 patients (46% female, median age 69 years [IQR 62-74]) had undergone successful device implantation for the treatment of HFrEF (53%) and HFpEF (47%). Sixty patients had a complete 12 month follow-up. The median follow-up was 351 days (interquartile range [IQR] 202-370). Six (7%) patients died during follow-up (8.6 deaths per 100 patient-years; 95% confidence interval [CI] 2.7 to 15.5), all of which had HFrEF. The median predicted mortality rate for the overall study population was 12.2 deaths per 100 patient-years (95% CI 10.2 to 14.7). While the observed mortality rate (0 deaths per 100 patient-years) was significantly lower than the median predicted mortality rate (9.3 deaths per 100 patient-years; 95% CI 8.4 to 11.1) in patients with HFpEF (-9.3 deaths per 100 patient-years; 95% CI -11.1 to -8.4), there was no difference in patients with HFrEF (-3.6 deaths per 100 patient-years; 95% CI -9.5 to 3.0). Four deaths were HF-related deaths (5.7 HF-related deaths per 100 patient-years; 95% CI 1.4 to 11.9; 10.8 HF-related deaths per 100 patient-years; 95% CI 2.5 to 23.1 in the HFrEF subgroup). CONCLUSIONS: In patients with HFpEF, the mortality rate following AFR implantation was lower than the predicted mortality rate. Dedicated randomised, controlled trials are needed - and currently ongoing - to investigate whether the AFR improves mortality.

RESUMO

BACKGROUND: The study's objective is to evaluate if Molsidomine (MOL), an anti-oxidant, anti-inflammatory, and anti-apoptotic drug, is effective in treating hyperoxic lung injury (HLI). METHODS: The study consisted of four groups of neonatal rats characterized as the Control, Control+MOL, HLI, HLI + MOL groups. Near the end of the study, the lung tissue of the rats were evaluated with respect to apoptosis, histopathological damage, anti-oxidant and oxidant capacity as well as degree of inflammation. RESULTS: Compared to the HLI group, malondialdehyde and total oxidant status levels in lung tissue were notably reduced in the HLI + MOL group. Furthermore, mean superoxide dismutase, glutathione peroxidase, and glutathione activities/levels in lung tissue were significantly higher in the HLI + MOL group as compared to the HLI group. Tumor necrosis factor-α and interleukin-1ß elevations associated with hyperoxia were significantly reduced following MOL treatment. Median histopathological damage and mean alveolar macrophage numbers were found to be higher in the HLI and HLI + MOL groups when compared to the Control and Control+MOL groups. Both values were increased in the HLI group when compared to the HLI + MOL group. CONCLUSIONS: Our research is the first to demonstrate that bronchopulmonary dysplasia may be prevented through the protective characteristics of MOL, an anti-inflammatory, anti-oxidant, and anti-apoptotic drug. IMPACT: Molsidomine prophylaxis significantly decreased the level of oxidative stress markers. Molsidomine administration restored the activities of antioxidant enzymes. Molsidomine prophylaxis significantly reduced the levels of inflammatory cytokines. Molsidomine may provide a new and promising therapy for BPD in the future. Molsidomine prophylaxis decreased lung damage and macrophage infiltration in the tissue.

RESUMO

BACKGROUND: In 12.5-56% of extremely low birth weight (ELBW) infants treated in newborn units, acute kidney injury (AKI) develops. Some of these infants may need renal replacement therapy for several reasons including hyperkalemia, hypovolemia and resistant acidosis. METHODS: All ELBW infants who were followed in our hospital between January 2015 and December 2017 and who lived longer than 48 hours were assessed. Patients were followed for AKI and peritoneal dialysis (PD). RESULTS: AKI developed in 25 of 201 ELBW infants. PD was administered to nine patients. PD was initiated at a median of 11 days (2-22 days) for all patients due to hyperkalemia which did not respond to medical treatment. Three of the nine infants who received PD died while dialysis was ongoing. The remaining six patients completed PD successfully. In these patients, the serum potassium value returned to normal in three days, and dialysis was continued for a median of 93 hours (40-172 hours). Dialysis leakage occurred in two patients, and hyperglycemia developed in two patients. On average, diuresis started at the 25th hour (8-40th hour). CONCLUSIONS: In the renal failure treatment of ELBW infants, PD is the only option which can be used for many units. It was found that in ELBW infants, who had wider peritoneal surface when compared to their body weight, biochemical values recovered rapidly with PD, and diuresis started a short while later in most patients.

RESUMO

OBJECTIVE: We aimed to evaluate the efficacy of combined (ibuprofen+paracetamol) medical therapy in cases of persistent haemodynamically significant patent ductus arteriosus that are resistant to standard medical monotherapy (ibuprofen and/or paracetamol) in this retrospective multi-centre study. METHODS: The combined therapy included the administration of 15mg/kg/dose of paracetamol every 6 h for 3 days and ibuprofen at an initial dose of 10mg/kg/dose followed by 5 mg/kg/dose every 24 h. After 2 days following the administration of the last dose, the researchers evaluated the efficacy of combined treatment by conducting an echocardiographic examination. RESULTS: Of all 42 patients who received combined therapy, 37 (88.1%) patients exhibited closure of the haemodynamically significant patent ductus arteriosus without requiring surgical ligation. Patients who did not respond to combined therapy had a higher mean birth weight and gestational age compared to those who responded (p < 0.05). CONCLUSION: The researchers believe the success of ibuprofen and paracetamol in haemodynamically significant patent ductus arteriosus treatment may be due to their synergistic efficacy and inhibition of the prostaglandin synthesis pathway through different enzymes. The results of our retrospective trial suggest that combination therapy with paracetamol and ibuprofen can be attempted when monotherapy is unsuccessful in treating haemodynamically significant patent ductus arteriosus, especially in centres without a surgical department.

RESUMO

BACKGROUND: Hypoxic-ischemic encephalopathy (HIE) is a condition that may cause multiple organ dysfunction and has a high rate of mortality and morbidity. Therapeutic hypothermia is the only proven treatment that decreases the sequel and mortality rate of neonates that are born after 36 weeks of pregnancy and have moderate-severe HIE. METHODS: Our study was a single-center, retrospective study that includes newborns (gestational age ≥ 36 weeks) who underwent therapeutic hypothermia due to hypoxic-ischemic encephalopathy between 2010 and 2020. We evaluated 125 patients who were diagnosed with moderate to severe HIE and received therapeutic hypothermia. Demographic and clinical data were obtained from electronic medical records and patient files. The patients were separated into two groups as exitus group (n = 39) and discharged group (n = 86). We aimed to evaluate factors affecting mortality. RESULTS: We determined that the median resuscitation times were longer in the delivery room [retrospectively, 10th minutes (0-30) vs. 1 min (0-20), p < 0.05], the tenth min APGAR scores were lower [respectively, 4 (0-7) vs. 6 (3-10), p < 0.05], and the median pH value in the first blood gas taken was lower [respectively, 6.87 (6.4-7.14) vs. 6.90 (6.58-7.12), p < 0.05] in the exitus group. We also determined that multiple organ dysfunction is seen more often in the exitus group. DISCUSSION: This study demonstrated that the depth of acidosis in the blood gas, multiple organ dysfunction, and the existence of early-onset seizures are the signs of poor prognosis. Therefore, physicians need to be aware of such prognostic factors to follow these patients more closely in terms of possible complications and to inform their parents.

RESUMO

Abstract Transcatheter aortic valve implantation (TAVI) is an alternative for high-risk aortic valve replacement. There are limited data related to the late complications of TAVI. Deep aortic prosthetic valve implantation can cause direct erosive perforation of anterior mitral leaflet or erosive endothelial lesion which predisposes the tissue to infective endocarditis. Our report emphasizes anterior mitral leaflet perforation after TAVI, which may be seen especially in patients exposed to sepsis.

RESUMO

Introduction: Intravenous immunoglobulin (IVIG) has been widely used to treat the hemolytic disease of the newborn (HDN). Although it has been shown that IVIG treatment reduces the duration of phototherapy and hospitalization, the use of IVIG in hemolytic disease due to ABO incompatibility has been controversial in recent years. This study aimed to investigate the role of IVIG in the prevention of exchange transfusion in infants with ABO HDN who presented with bilirubin levels at or above the level of exchange transfusion. Materials and Methods: This study evaluated the data of infants with ABO HDN in the Turkish Neonatal Jaundice Online Registry. The infants with ABO HDN who met the total serum bilirubin level inclusion criteria (within 2-3 mg/dL of exchange transfusion or even above exchange transfusion level) were included in the study according to the guidelines from the American Academy of Pediatrics and the Turkish Neonatal Society. All patients were managed according to the unit protocols recommended by these guidelines and received light-emitting diode (LED) phototherapy. Infants who only received LED phototherapy, and who received one dose of IVIG with LED phototherapy were compared. Results: During the study period, 531 term infants were included in the study according to inclusion criteria. There were 408 cases in the phototherapy-only group, and 123 cases in the IVIG group. The demographic findings and the mean bilirubin and reticulocyte levels at admission were similar between the groups (p > 0.05), whereas the mean hemoglobin level was slightly lower in the IVIG group (p = 0.037). The mean age at admission was earlier, the need for exchange transfusion was higher, and the duration of phototherapy was longer in the IVIG group (p < 0.001, p = 0.001, and p < 0.001, respectively). The rate of re-hospitalization and acute bilirubin encephalopathy (ABE) was higher in the IVIG group (p < 0.001 and p = 0.01, respectively). Conclusion: In this study, we determined that one dose of IVIG did not prevent an exchange transfusion nor decrease the duration of phototherapy in infants, who had bilirubin levels near or at exchange transfusion level, with hemolytic disease due to ABO incompatibility.

RESUMO

BACKGROUND: Implantation of the atrial flow regulator (AFR) to create an interatrial left-to-right shunt has been shown to be safe and feasible to reduce intracardiac filling pressures in patients with heart failure (HF). OBJECTIVES: We aimed to assess the effect of AFR implantation on 12-month mortality and hospitalization rates in patients with reduced (HFrEF) or preserved HF (HFpEF). METHODS: One-year follow-up data from 34 subjects enrolled at a single PRELIEVE center were analyzed. The 12-month predicted mortality was calculated using the Meta-Analysis Global Group in Chronic Heart Failure (MAGGIC) risk score. Patients were divided into two groups, according to their history of hospitalizations for HF. RESULTS: Study data of 34 patients (HFrEF: 24 [70.6%]; HFpEF: 10 [29.4%]) were assessed. Median follow-up duration was 355 days. In total, 14 (41.2%) patients were hospitalized during the follow-up period and 6 (17.6%) of these patients were hospitalization for HF (HHF). A total of 24 hospitalizations occurred in this period and 8 (33%) hospitalizations were for HHF. The median baseline MAGGIC score was 23 and the median predicted mortality was 13.4/100 patient years. Observed mortality was 3.1/100 patient years. The observed survival (97%) was 10.3% (95% confidence interval 3.6-17.5%, p = 0.004) better than the predicted survival (86.6%). CONCLUSION: Our results suggest that AFR implantation has favorable effects on mortality in patients with heart failure, regardless of ejection fraction. Furthermore, compared to baseline, left ventricular filling pressure (assessed by echocardiography) decreased significantly without right side volume overload at the 1­year follow-up.

RESUMO

AIM: Inflammation and oxidate stress are significant factors in the pathogenesis of bronchopulmonary dysplasia (BPD). The aim of this study is to investigate the efficacy of apocynin (APO), an anti-inflammatory, antioxidant, and antiapoptotic drug, in the prophylaxis of neonatal hyperoxic lung injury. METHOD: This experimental study included 40 neonatal rats divided into the control, APO, BPD, and BPD + APO groups. The control and APO groups were kept in a normal room environment, while the BPD and BPD + APO groups were kept in a hyperoxic environment. The rats in the APO and BPD + APO groups were administered intraperitoneal APO, while the control and BPD rats were administered ordinary saline. At the end of the trial, lung tissue was evaluated with respect to the degree of histopathological injury, apoptosis, oxidant and antioxidant capacity, and severity of inflammation. RESULT: The BPD and BPD + APO groups exhibited higher mean histopathological injury and alveolar macrophage scores compared to the control and APO groups. Both scores were lower in the BPD + APO group in comparison to the BPD group. The BPD + APO group had a significantly lower average of TUNEL positive cells than the BPD group. The lung tissue examination indicated significantly higher levels of mean malondialdehyde (MDA), total oxidant status (TOS), tumor necrosis factor-α (TNF-α), and interleukin-1ß (IL-1ß) in the BPD group compared to the control and APO groups. While the TNF-α and IL-1ß levels of the BPD + APO group were similar to that of the control group, the MDA and TOS levels were higher compared to the controls and lower compared to the BPD group. The BPD group demonstrated significantly lower levels/activities of mean total antioxidant status, glutathione reductase, superoxide dismutase, glutathione peroxidase in comparison to the control and APO groups. While the mean antioxidant enzyme activity of the BPD + APO group was lower than the control group, it was significantly higher compared to the BPD group. CONCLUSION: This is the first study in the literature to reveal through an experimental neonatal hyperoxic lung injury that APO, an anti-inflammatory, antioxidant, and antiapoptotic drug, exhibits protective properties against the development of BPD.

RESUMO

Background    Left atrial decompression has emerged a new option to treat patients with heart failure and dyspnea at rest or during exercise. Here we report the impact of atrial flow regulator (AFR) implantation on hemodynamic parameters in patients at our center with heart failure and with reduced (HFrEF) or with preserved left ventricular ejection fraction (HFpEF).Material and methods    The PRELIEVE trial is designed to assess the safety and efficacy of the AFR in patients with HFrEF or HFpEF. Patients with left ventricular end-diastolic pressure ≥15 mmHg at rest or ≥25 mmHg during exercise and with an ejection fraction ≥15 % were enrolled. Echocardiographic data, 6­min walking distance, Kansas City Cardiomyopathy Questionnaire, and brain natriuretic peptide levels were assessed pre- and post-AFR implantation and at 3 mos. Invasive hemodynamic assessments were also performed pre- and post-AFR implantation and at 3 mos.Results    27 (69.2 %) patients with HFrEF and 12 (30.8 %) patients with HFpEF at our center were enrolled in this study. A significant decrease was observed in pulmonary arterial wedge pressure regardless of EF (p=0.007 for HFrEF and p=0.03 for HFpEF). No significant difference of mean pulmonary arterial pressure, right arterial pressure and cardiac output (CO) existed at 3 months compared with pre-implantation baseline values.Conclusion    AFR implantation led to decrease in left ventricle filling pressure without the deleterious impact on CO and right heart function regardless of ejection fraction.

RESUMO

BACKGROUND: Oxidative stress and inflammation play a critical role in the etiopathogenesis of bronchopulmonary dysplasia (BPD). The aim of this study was to evaluate the preventive effect of Chrysin (CH), an antioxidant, antiinflammatory, antiapoptotic and antifibrotic drug, on hyperoxia-induced lung injury in a neonatal rat model. METHODS: Forty infant rats were divided into four groups labeled the Control, CH, BPD, and BPD + CH. The control and CH groups were kept in a normal room environment, while the BPD and BPD + CH groups were kept in a hyperoxic (90-95%) environment. At the end of the study, lung tissue was evaluated with respect to apoptosis, histopathological damage and alveolar macrophage score as well as oxidant capacity, antioxidant capacity, and inflammation. RESULTS: Compared to the BPD + CH and control groups, the lung tissues of the BPD group displayed substantially higher levels of MDA, TOS, TNF-α, and IL-1ß (p < 0.05). While the BPD + CH group showed similar levels of TNF-α and IL-1ß as the control group, MDA and TOS levels were higher than the control group, and significantly lower than the BPD group (p < 0.05). The BPD group exhibited considerably lower levels of TAS, SOD, GSH, and GSH-Px in comparison to the control group (p < 0.05). The BPD and BPD + CH groups exhibited higher mean scores of histopathological damage and alveolar macrophage when compared to the control and CH groups (p ≤ 0.0001). Both scores were found to be lower in the BPD + CH group in comparison to the BPD group (p ≤ 0.0001). The BPD + CH group demonstrated a significantly lower average of TUNEL and caspase-3 positive cells than the BPD group. CONCLUSION: We found that prophylaxis with CH results in lower histopathological damage score and reduces apoptotic cell count, inflammation and oxidative stress while increasing anti-oxidant capacity.

RESUMO

BACKGROUND: Coronavirus disease 2019 (COVID-19) usually leads to a mild infectious disease course in children, while serious complications may occur in conjunction with both acute infection and neurological symptoms, which have been predominantly reported in adults. The neurological complications in these patients vary based on patient age and underlying comorbidities. Data on clinical features, particularly neurological features, and prognostic factors in children and adolescents are limited. This study provides a concise overview of neurological complications in pediatric COVID-19 cases. MATERIALS AND METHODS: The retrospective study reviewed medical records of all patients who were admitted to our hospital and were diagnosed with COVID-19 by real-time reverse-transcription polymerase-chain-reaction (RT-PCR) assay between 11 March 2020 and 30 January 2021. Patients with a positive PCR result were categorized into two groups: outpatient departments patients and inpatient departments (IPD). RESULTS: Of the 2530 children who underwent RT-PCR during the study period, 382 (8.6%) were confirmed as COVID-19 positive, comprising 188 (49.2%) girls and 194 (50.8%) boys with a mean age of 7.14±5.84 (range, 0-17) years. Neurological complications that required hospitalization were present in 34 (8.9%) patients, including seizure (52.9%), headache (38.2%), dizziness (11.1%) and meningoencephalitis (5.8%). CONCLUSION: The results indicated that neurological manifestations are not rare in children suffering from COVID-19. Seizures, headaches, dizziness, anosmia, ageusia and meningoencephalitis are major neurological manifestations during acute COVID-19 disease. Although seizures were the most common cause of hospitalization in IPD patients, the frequency of meningoencephalitis was quite high. Seizures were observed as febrile seizures for children under 6 years of age and afebrile seizures for those over 6 years of age. Febrile seizure accounted for half of all seizure children.

RESUMO

BACKGROUND: Since there was no proven treatment of coronavirus disease 2019 (COVID-19), hydroxychloroquine-azithromycin (HCQ-AZM) combination is being used in different countries as a treatment option. Many controversies exist related to the safety and effectiveness of this combination, and questions about how HCQ-AZM combination affects the ventricular repolarization are still unknown. OBJECTIVE: The aim of the study was to show whether the hydroxychloroquine-azithromycin (HCQ-AZM) combination prolonged Tpeak-to-end (TpTe) duration and TpTe/QT interval ratio or not. METHODS: One hundred and twenty-six consequent COVID-19(+) patients meeting the study criteria were enrolled in this study. Baseline ECGs were obtained immediately after hospitalization and before commencing the HCQ-AZM combination. On-treatment ECG was obtained 24-48 hr after the loading dose of HCQ/AZM. ECG parameters including PR interval, QRS duration, QT interval, QTc interval, TpTe duration, and TpTe/QT interval ratio were assessed. Demographic and laboratory findings were collected from an electronic recording system. RESULTS: ECGs of 126 COVID-19(+) patients who received HCQ-AZM combination were assessed. Mean baseline QTc (by Fridericia formula), TpTe, and TpTe/QT ratio were 420.0 ± 26.5 ms, 82.43 ± 9.77 ms, and 0.22 ± 0.02, respectively. On-treatment QTc, TpTe and TpTe/QT ratio were 425.7 ± 27.18 ms, 85.17 ± 11.17 ms, and 0.22 ± 0.03, respectively. No statistically significant acute impacts of HCQ-AZM combination on TpTe duration and TpTe/QT interval ratio were observed compared with baseline values. No ventricular tachycardia/fibrillation and the significant conduction delays were seen during in-hospital follow-up. CONCLUSION: HCQ-AZM combination increased TpTe duration. However, no significant impact on TpTe/QT interval ratio was observed.

RESUMO

AIMS: Attenuating exercise-induced elevated left atrial pressure with an atrial shunt device is under clinical investigation for treatment of symptomatic heart failure (HF). METHODS AND RESULTS: PRELIEVE was a prospective, non-randomised, multicentre, first-in-man study in symptomatic HF patients with reduced (HFrEF) or preserved (HFpEF) ejection fraction and pulmonary capillary wedge pressure (PCWP) ≥15 mmHg at rest or ≥25 mmHg during exercise. Here, we provide follow-up data up to 1 year after implantation of the Atrial Flow Regulator (AFR) device. The AFR was successfully implanted in 53 patients (HFrEF n = 24 and HFpEF n = 29). Two patients were not enrolled due to an unsuccessful transseptal puncture. There was one device embolisation into the left atrium, which required surgical removal. One patient experienced a serious procedure-related adverse event (post-procedural bleeding and syncope). All patients with sufficient echocardiography readout confirmed device patency with left-right shunt both at 3 (n = 47/51, 92%) and 12 (n = 45/49, 92%) months. At 3 months, rest PCWP decreased by 5 (-12, 0) mmHg (P = 0.0003, median Q1, Q3). No patient developed a stroke, worsening of right heart function or significant increase of pulmonary artery pressure. Six (6/53, 11%) patients were hospitalised for worsening of HF and three (3/53, 6%) patients died. We observed improvements in New York Heart Association functional class, 6-min walking distance and quality of life (Kansas City Cardiomyopathy Questionnaire) in certain patients. CONCLUSIONS: Implantation of the AFR device in HF patients was feasible. No shunt occlusion, stroke or new right HF was observed during the 1-year follow-up, with clinical improvements in certain patients.

RESUMO

PURPOSE: In this study, we compared the efficacy of the RAM cannula and the short binasal prong (SBP) as noninvasive ventilation (NIV) interfaces in preterm infants with respiratory distress syndrome (RDS). MATERIALS AND METHODS: Premature infants with RDS who required NIV were randomized in the RAM cannula and SBP groups within the first half hour. The groups were compared in terms of their need for invasive ventilation, their surfactant use, and their morbidities. RESULTS: We assessed 126 patients (62 SBPs and 64 RAM cannulas). Clinical and demographic features of the groups were similar. Within the first 72 hours, the RAM cannula group showed a higher need for invasive ventilation (32.8 and 9.6%, p = .002, respectively), surfactant (42.1 and 19.3%, p = .007, respectively), and rate of pulmonary hemorrhage was also higher. There were no differences between the groups in terms of other morbidities. CONCLUSIONS: In preterm infants with RDS, RAM cannula use as an interface for NIV results in increased invasive ventilation and surfactant use.
