Evaluation of cardiac findings in mucopolysaccharidosis.

PURPOSE: Mucopolysaccharidoses (MPS) are a group of rare genetic diseases and heart involvement is one of the important conflicts in most types, which may cause serious complications. We used M-Mode and two-dimensional speckle tracking echocardiography (2D-STE) to explore cardiovascular involvements in MPS patients. METHOD: The present cross-sectional study investigated the frequency of cardiac involvements in MPS patients. Included participants were MPS types I, II, III, IV, and VI who underwent specialized echocardiography exams to assess valvular function, systolic and diastolic function, left ventricular ejection fraction (LVEF), and global longitudinal strain (GLS). RESULTS: 35 patients were enrolled in this study. The total mean age of patients was 9.58 ± 5.11 years and 71.4% were male. Type IV (40%) and type III (31.4%) were the most frequent MPS. Although LVEF did not differ notably among MPS types, GLS was significantly different (p = 0.029). Mitral regurgitation was observed remarkably more in MPS type III (p = 0.001) while mitral stenosis was more common in type III (p = 0.007). There was a significant association between LVEF and GLS (ß= -0.662; p = 0.025) and between LVEF and MPS type (ß = 1.82; p = 0.025) when adjusted for GLS. CONCLUSION: Cardiac complications are very common and are one of the most important causes of death in MPS patients. 2D-STE seems to be superior to M-Mode for detection of early and subclinical cardiac dysfunction in MPS patients.

Incidence of rhabdomyolysis occurrence in psychoactive substances intoxication: a systematic review and meta-analysis.

Rhabdomyolysis is a potentially life-threatening condition induced by diverse mechanisms including drugs and toxins. We aimed to investigate the incidence of rhabdomyolysis occurrence in intoxicated patients with psychoactive substances. In this review, three databases (PubMed, Scopus, Web of Science) and search engine (Google Scholar) were searched by various keywords. After the screening of retrieved documents, related data of included studies were extracted and analyzed with weighted mean difference (WMD) in random effect model. The highest incidence of rhabdomyolysis was observed in intoxication with heroin (57.2 [95% CI 22.6-91.8]), amphetamines (30.5 [95% CI 22.6-38.5]), and cocaine (26.6 [95% CI 11.1-42.1]). The pooled effect size for blood urea nitrogen (WMD = 8.78, p = 0.002), creatinine (WMD = 0.44, p < 0.001), and creatinine phosphokinase (WMD = 2590.9, p < 0.001) was high in patients with rhabdomyolysis compared to patients without rhabdomyolysis. Our results showed a high incidence of rhabdomyolysis induced by psychoactive substance intoxication in ICU patients when compared to total wards. Also, the incidence of rhabdomyolysis occurrence was high in ICU patients with heroin and amphetamine intoxication. Therefore, clinicians should anticipate this complication, monitor for rhabdomyolysis, and institute appropriate treatment protocols early in the patient's clinical course.

Childhood Obesity Is Associated With Subclinical Left Ventricular Dysfunction Detected by Speckle Tracking Echocardiography.

Childhood obesity is related to cardiac structural and functional changes, increasing the risk of heart disease. Sixty normotensive children were assigned based on body mass index (BMI) into normal weight, overweight, and obese groups and examined by two-dimensional speckle tracking echocardiography (2D-STE). Weight (P = .001) and BMI (P = .001) differed significantly among the 3 groups. Left ventricular (LV) strain (P = .001) and strain rate (P = .002) in overweight and obese children (P = .001) were significantly lower compared to normal weight group. LV mass in obese children was notably larger compared to overweight children (P = .047). LV strain was associated with age (P = .031), weight (P = .001), and height (P = .022). There was an association between LV strain rate with weight (P = .001) and between left atrial area and height of children (P = .007). Obesity in normotensive obese children is associated with subclinical alteration of LV dimension and myocardial longitudinal strain recognized by 2D-STE.

Investigating Causes of Medical Errors in Intensive Care Units in Iran: A Cross-sectional Study.

Background: Medical errors cause disability and mortality in intensive care units (ICUs). We aimed to determine the occurrence and causes of medical errors in the ICUs of Iran. Methods: In this cross-sectional study, data from the family complaint files referred to The disciplinary authority of Iran Medical Council was retrospectively reviewed to explore the causes of medical errors. Statistical analysis was performed in SPSS Version 26.0. Results: A total of 293 complaint files were referred to the disciplinary commission from 2014 to 2019, of which 95 files were related to medical errors in ICUs. The median age of patients was 62 years (46-74 years) and 52 (54.7%) patients were men. Also, 37 (38.9%) patients had decreased levels of consciousness and 42 (42.2%) patients had cardiovascular disease. A total of 40 (42.1%) patients experienced a single medical error and 55 (57.9%) patients experienced more than 1. Causes of medical errors in patients were physician's or nurse's negligence in 53 (55.8%) patients, weak interaction of physician and nurse with the patient and family members in 11 (11.6%) patients, weak interprofessional interaction among physicians in 7 (7.4%) patients, equipment and structure of ICUs in 7 (7.4 patients, nature of ICUs and patients in 6 (6.3%) patients, weak physician-nurse interprofessional interaction in 5 (5.2%) patients) patients, low attention of the physician and the nurse to medication safety in 6 (6.3%) patients. Conclusion: Patient safety is impacted by a variety of medical mistakes. Interprofessional strategies can be developed and put into action to mitigate medical errors in ICUs.

Assessment of renal function indexes in methamphetamine or tramadol intoxication adults to the emergency departments: a systematic review and meta-analysis.

BACKGROUND: Renal dysfunction is one of the adverse effects observed in methamphetamine (MET) or tramadol abusers. In this study, we aimed to review articles involving intoxication with MET or tramadol to assess the occurrence of renal dysfunction. METHODS: Two researchers systematically searched PubMed, Scopus, Web of Sciences, and Google Scholar databases from 2000 to 2022. All articles that assessed renal function indexes including creatine, Blood Urea Nitrogen (BUN), and Creatine phosphokinase (CPK) in MET and tramadol intoxication at the time of admission in hospitals were included. We applied random effect model with Knapp-Hartung adjustment for meta-analysis using STATA.16 software and reported outcomes with pooled Weighted Mean (WM). RESULTS: Pooled WM for BUN was 29.85 (95% CI, 21.25-38.46) in tramadol intoxication and 31.64(95% CI, 12.71-50.57) in MET intoxication. Pooled WM for creatinine in tramadol and MET intoxication was respectively 1.04 (95% CI, 0.84-1.25) and 1.35 (95% CI, 1.13-1.56). Also, pooled WM for CPK was 397.68(376.42-418.94) in tramadol and 909.87(549.98-1269.76) in MET intoxication. No significance was observed in publication bias and heterogeneity tests. CONCLUSION: Our findings showed that tramadol or MET intoxication is associated with a considerably increased risk of renal dysfunction that may result in organ failure.

Bentall Procedure to Repair Acute Type a Aortic Dissection in Pregnant Marfan Syndrome Woman With Preservation of Pregnancy.

Background: Acute aortic dissection is the most common life-threatening disorder classically presenting with tearing chest pain radiating to the back yet can have deceiving clinical presentations.Case presentation: The patient was a 22-year-old pregnant woman (gravida 6, para 4, abortion1) at 26 weeks of gestation. She was a known case of Marfan syndrome who developed acute type A aortic dissection during pregnancy. Repair of aortic dissection was done through the Bentall procedure with a composite mechanical valved conduit while Fetal heart rate (FHR) was simultaneously monitored during surgery. Three months after surgical repair, the newborn was delivered via cesarean, and both mother and baby survived without any complications.Conclusions: In this case, we demonstrated that repair of type A aortic dissection can be done in pregnant women with preservation of fetus in the uterus through close cooperation among all members of a multi-disciplinary team.

Topical and Intravenous Tranexamic Acid in Acyanotic Children Undergoing Congenital Heart Surgery: A Randomized Clinical Trial.

INTRODUCTION: Postoperative bleeding is a common complication in congenital heart surgery. We aimed to evaluate effects of topical and intravenous tranexamic acid (TXA) administration on postoperative hemoglobin and bleeding in children with acyanotic congenital heart disease (CHD). METHODS: In this randomized clinical trial, 50 acyanotic CHD children were allocated into two groups of topical (n = 25) and infusion (n = 25). Children in the infusion group were given intravenous TXA 50 mg/kg-1 after sternotomy. Children in topical group were given 50 mg/kg-1 TXA added to 20 mL of saline intrapericardially before sternal closure. Primary endpoint of study was comparison of postoperative hemoglobin and bleeding between topical and infusion groups. A linear mixed model (LMM) was used to estimate longitudinal changes in postoperative endpoints. RESULTS: We did not observe significant differences in children's characteristics between two groups. Also, intraoperative and postoperative outcomes did not differ between two groups but children with intravenous TXA experienced significantly longer intubation time than topical children (P = 0.047). LMM analysis revealed that postoperative bleeding in topical group was lower compared to infusion group (P = 0.036). Also, age of children had a significant effect on mean changes of hemoglobin during postoperative care (ß = -0.27, P = 0.030). No children died and none had serious postoperative complications such as seizures and reoperation. CONCLUSIONS: We found that topical TXA is not superior to intravenous administration in management of blood loss. Also, no additional effect was found about topical TXA in further reducing transfusion rates and postoperative complications in acyanotic CHD children undergoing cardiac surgery.

Regional cerebral blood flow and brain atrophy in mild cognitive impairment and Alzheimer's disease.

Objectives: A decline in the regional cerebral blood flow (CBF) is proposed to be one of the initial changes in the Alzheimer's disease process. To date, there are limited data on the correlation between CBF decline and gray matter atrophy in mild cognitive impairment (MCI) and AD patients. to investigate the association between CBF with the gray matter structural parameters such as cortical volume, surface area, and thickness in AD, MCI, and healthy controls (HC). Methods: Data from three groups of participants including 39 HC, 82 MCI, and 28 AD subjects were obtained from the Alzheimer's disease Neuroimaging Initiative (ADNI). One-way ANOVA and linear regression were used to compare data and find a correlation between structural parameters such as cortical volume, surface area, and thickness and CBF which measured by arterial spin labeling (ASL)-MRI. Results: Our findings revealed a widespread significant correlation between the CBF and structural parameters in temporal, frontal, parietal, occipital, precentral gyrus, pericalcarine cortex, entorhinal cortex, supramarginal gyrus, fusiform, precuneus, and pallidum. Conclusion: CBF decline may be a useful biomarker for MCI and AD and accurately reflect the structural changes related to AD. According to the present results, CBF decline, as measured by ASL-MRI, is correlated with lower measures of structural parameters in AD responsible regions. It means that CBF decline may reflect AD-associated atrophy across disease progression and is also used as an early biomarker for AD and MCI diagnosis.

Preliminary report of Iranian Registry of Alzheimer's disease in Tehran province: A cross-sectional study in Iran.

Background and Aims: Alzheimer's disease (AD) is the main cause of dementia and over the 55 million people live with dementia worldwide. We aimed to establish the first database called the Iranian Alzheimer's Disease Registry to create a powerful source for future research in the country. In this report, the design and early results of the Iranian Alzheimer's Disease Registry will be described. Methods: We performed this multicenter investigation and patients' data including age, sex, educational level, disease status, Mini-Mental State Examination (MMSE), and Geriatric Depression Scale (GDS) from 2018 to 2021 were collected, registered, and analyzed by GraphPad Prism software. Results: Totally 200 AD patients were registered in our database. 107 (54%) were women and age of 147 (74%) were over 65. The mean age for men and women was 76.20 ± 8.29 and 76.40 ± 8.83 years, respectively. 132 (66%) were married and 64 (32%) were illiterate. Also, 94 (47%) were in the moderate stage of disease, and 150 (75%) lived at home together with their families. The most frequent neurological comorbidity was psychosis (n = 72, 36%), while hypertension was the most common non-neurological comorbidity (n = 104, 52%). The GDS score of women in the mild stage (5.23 ± 2.9 vs. 6.9 ± 2.6, p = 0.005) and moderate stage (5.36 ± 2.4 vs. 8.21 ± 2.06, p = <0.001) of the disease was significantly greater than men. In univariate analysis, MMSC score was remarkably associated with stroke (ß = -2.25, p = 0.03), psychosis (ß = -2.18, p = 0.009), diabetes (ß = 3.6, p = <0.001), and hypercholesteremia (ß = 1.67, p = 0.05). Also, the MMSE score showed a notable relationship with stroke (ß = -2.13, p = 0.05) and diabetes (ß = 3.26, p = <0.001) in multivariate analysis. Conclusion: Iranian Alzheimer's Disease Registry can provide epidemiological and clinical data to use for purposes such as enhancing the current AD management in clinical centers, filling the gaps in preventative care, and establishing effective monitoring and cure for the disease.

Linear mixed model analysis to evaluate correlations between remdesivir adverse effects with age and gender of patients with mild Covid-19 pneumonia.

We aimed to assess longitudinal changes in clinical indexes of corona disease 2019 (Covid-19) patients with mild pulmonary infection during 5 days of remdesivir therapy and determine the effect of age and gender on remdesivir adverse effects (AE). Patients' clinical data including inflammatory markers, liver and renal function tests, and heart rate (HR) were extracted from medical records. Linear mixed model (LMM) was used to analyze longitudinal changes in patients' clinical indexes. Gender and age were inserted in LMM as covariates to find their correlation with AE and clinical indexes. Of 84 patients, 35 patients met our criteria for the study. There were significant increases in mean levels of white blood cell (WBC; p = 0.005), alanine aminotransferase (ALT; p = 0.001), aspartate aminotransferase (p = 0.001), blood urea nitrogen (BUN; p = 0.001), and creatinine (p = 0.006), whereas mean levels of erythrocyte sedimentation rate (p = 0.005), C-reactive protein (p = 0.001), alkaline phosphatase (p = 0.001), and potassium (p = 0.003) decreased significantly. Estimated glomerular filtration rate (p = 0.001) and HR (p = 0.001) showed a notable decline over the course of treatment. LMM analysis showed that mean changes in WBC (ß = 0.94, p = 0.029), creatinine (ß = 0.12, p = 0.020), and HR (ß = 6.47, p = 0.008) were greater in males than in females. Also, age of patients had a significant effect on the mean changes of WBC (ß = -0.02, p = 0.023), sodium (ß = -0.06, p = 0.010), BUN (ß = 0.23, p = 0.001), and HR (ß = -0.29, p = 0.001). Despite no renal and liver dysfunction, Covid-19 patients with mild pulmonary infection may develop some remdesivir AE and attributed side effects might be affected by gender and age of patients.

Biventricular strain and strain rate impairment shortly after surgical repair of tetralogy of Fallot in children: A case-control study.

Background: Early biventricular dysfunction in repaired tetralogy of Fallot (TOF) children may lead to poor clinical outcomes. We aimed to assess biventricular function in TOF children before and after surgery by speckle tracking echocardiography (STE) and compare them with the controls. Methods: Twenty repaired TOF children and 20 normal children as controls were assessed by STE. Tricuspid annular plane systolic excursion (TAPSE), left ventricular ejection fraction (LVEF), biventricular strain, and strain rate were compared before and after surgery and between TOF children and controls. Results: Postoperative LVEF (p = 0.001), strain (p = 0.001), and strain rate (p = 0.001) for left ventricle improved significantly compared to preoperative phase. However, postoperative left ventricular strain (p = 0.05) and strain rate (p = 0.01) in TOF children were significantly impaired compared to controls. Postoperative LVEF was correlated inversely with postoperative strain rate (r = -0.40, p = 0.04). Postoperative TAPSE (p = 0.001), strain (p = 0.001), and strain rate (p = 0.001) for right ventricle significantly worsened when compared with the preoperative phase. Moreover, postoperative TAPSE (p = 0.001), strain (p = 0.001), and strain rate (p = 0.01) were significantly impaired compared to controls. Postoperative right ventricular strain rate was correlated significantly with the weight of children (r = 0.48, p = 0.02), and postoperative left ventricular strain showed significant correlations with aortic clamp time (r = 0.44, p = 0.04) and with ICU stay (r = -0.46, p = 0.04). Conclusion: Despite normal LVEF, TOF children exhibit impaired left ventricular strain and strain rate after surgery. TAPSE, strain, and strain rate for the right ventricle worsen after surgical repair. STE-driven strain can be used to detect early ventricular dysfunction and the associated prognostic implications.

Metabolic disturbance affects postoperative cognitive function in patients undergoing cardiopulmonary bypass.

OBJECTIVES: Postoperative delirium is a common neuropsychiatric syndrome after coronary artery bypass grafting (CABG). We aimed to assess and compare clinical outcomes of CABG patients with delirium with a specific focus on the blood biochemical parameters. METHODS: This investigation was carried out on the 90 eligible patients undergoing CABG. Delirium was measured using the Neecham confusion scale and assessed patients were divided into two groups of delirium (n = 43) and non-delirium (n = 47). Preoperative variables and intraoperative and postoperative outcomes were compared. RESULTS: Delirium patients were older (p = 0.003) and had longer intubation time (p = 0.003). Non-delirium patients obtained a significantly higher Neecham confusion score (p = 0.001), and delirium patients experienced a hyperglycemic state at intraoperative (p = 0.004), intubation (p = 0.03), and extubation time (p = 0.02). Lower value of pH was seen at intubation (p = 0.03) and extubation periods (p = 0.001) in delirium group. A significant difference in base excess was observed between two groups at intubation (p = 0.04) and extubation periods (p = 0.004). Potassium level showed a significant decrease in delirium group at intubation (p = 0.01) and extubation periods (p = 0.001). Multivariate regression indicated that aging (OR = 1.08, p = 0.01), narcotic consumption (OR = 3.27, p = 0.05), DM (OR = 3.03, p=0.03), and prolonged intubation (OR = 1.18, p = 0.03) are predictors of delirium. Postoperative hyperglycemia (OR = 1.01, p = 0.002), low pH value (OR = 2.62, p = 0.02), and low potassium level (OR = 3.25, p = 0.03) are associated with development of delirium. CONCLUSIONS: Postoperative metabolic disturbance and electrolyte imbalances are closely related to the development of delirium after CABG and need to be considered more carefully. Aging, DM, and preoperative use of narcotics are strong predictors of delirium following CABG.

Linagliptin Protects Human SH-SY5Y Neuroblastoma Cells against Amyloid-ß Cytotoxicity via the Activation of Wnt1 and Suppression of IL-6 Release

Background: Alzheimer's disease is one of the neurodegenerative disorders typified by the aggregate of amyloid-ß (Aß) and phosphorylated tau protein. Oxidative stress and neuroinflammation, because of Aß peptides, are strongly involved in the pathophysiology of Alzheimer's disease (AD). Linagliptin shows neuroprotective properties against AD pathological processes through alleviation of neural inflammation and AMPK activation. Methods: We assessed the benefits of linagliptin pretreatment (at 10, 20, and 50 nM concentrations), against Aß1-42 toxicity (20 µM) in SH-SY5Y cells. The concentrations of secreted cytokines, such as TNF-α, IL-6, and IL-1ß, and signaling proteins, including pCREB, Wnt1, and PKCε, were quantified by ELISA. Results: We observed that Aß led to cellular inflammation, which was assessed by measuring inflammatory cytokines (TNF-α, IL-1ß, and IL-6). Moreover, Aß1-42 treatment impaired pCREB, PKCε, and Wnt1 signaling in human SH-SY5Y neuroblastoma cells. Addition of Linagliptin significantly reduced IL-6 levels in the lysates of cells, treated with Aß1-42. Furthermore, linagliptin prevented the downregulation of Wnt1 in Aß1-42-treated cells exposed. Conclusion: The current findings reveal that linagliptin alleviates Aß1-42-induced inflammation in SH-SY5Y cells, probably through the suppression of IL-6 release, and some of its benefits are mediated through the activation of the Wnt1 signaling pathway.

Case Report: Acute Intracardiac Thrombosis in Children With Coronavirus Disease 2019 (COVID-19).

We herein describe a case series of children with SARS-CoV-2 infection (COVID-19) complicated with acute intracardiac thrombosis. The diagnosis of COVID-19 was confirmed through the reverse transcription-polymerase chain reaction (RT-PCR). Transthoracic echocardiography of patients revealed large intracardiac mobile masses resected successfully via cardiac surgery. The underlying mechanisms of this thrombus in the COVID-19 infection may be attributed to the hypercoagulation and inflammatory state of the disease incurred by the SARS-CoV-2 virus.

Anti-aging Klotho Protects SH-SY5Y Cells Against Amyloid ß1-42 Neurotoxicity: Involvement of Wnt1/pCREB/Nrf2/HO-1 Signaling.

Alzheimer's disease (AD) is considered a prevalent neurological disorder with a neurodegenerative nature in elderly people. Oxidative stress and neuroinflammation due to amyloid ß (Aß) peptides are strongly involved in AD pathogenesis. Klotho is an anti-aging protein with multiple protective effects that its deficiency is involved in development of age-related disorders. In this study, we investigated the beneficial effect of Klotho pretreatment at different concentrations of 0.5, 1, and 2 nM against Aß1-42 toxicity at a concentration of 20 µM in human SH-SY5Y neuroblastoma cells. Our findings showed that Klotho could significantly and partially restore cell viability and decrease reactive oxygen species (known as ROS) and improve superoxide dismutase activity (SOD) in addition to reduction of caspase 3 activity and DNA fragmentation following Aß1-42 challenge. In addition, exogenous Klotho also reduced inflammatory biomarkers consisting of nuclear factor-kB (NF-kB), interleukin-1ß (IL-1ß), and tumor necrosis factor-α (TNF-α) in Aß-exposed cells. Besides, Klotho caused downregulation of Wnt1 level, upregulation of phosphorylated cyclic AMP response element binding (pCREB), and mRNA levels of nuclear factor erythroid 2-related factor 2 (Nrf2) and heme oxygenase 1 (HO-1) with no significant alteration of epsilon isoform of protein kinase C (PKCε) after Aß toxicity. In summary, Klotho could alleviate apoptosis, oxidative stress, and inflammation in human neuroblastoma cells after Aß challenge and its beneficial effect is partially exerted through appropriate modulation of Wnt1/pCREB/Nrf2/HO-1 signaling.

Right Atrial Thrombus in a COVID-19 Child Treated Through Cardiac Surgery.

We herein report a case of large intracardiac thrombus in a child with SARS-CoV-2 infection (COVID-19). The diagnosis of COVID-19 was confirmed through HRCT and RT-PCR. Transthoracic echocardiography revealed a large thrombus in the right atrium treated successfully via cardiac surgery. The underlying mechanisms of this thrombus in the COVID-19 infection may be attributed to the hypercoagulation and inflammatory condition incurred by the COVID-19 virus.

The Association Between Circulating Klotho and Dipeptidyl Peptidase-4 Activity and Inflammatory Cytokines in Elderly Patients With Alzheimer Disease.

INTRODUCTION: Klotho and Dipeptidyl Peptidase-4 (DPP4) are two proteins that modulate inflammatory pathways. We investigated the association between circulating klotho and DPP4 activity and their relationship with inflammatory cytokines, miR-29a, and miR-195 in Alzheimer Disease (AD). METHODS: This study was conducted on 16 AD patients and 16 healthy age-matched controls. Plasma levels of tumor necrosis factor-alpha (TNF-α), interleukin-1 beta (IL-1ß, interleukin-6 (IL-6), klotho, and DPP4 were measured by enzyme-linked immunosorbent assay. Plasma expression of miR-29a and miR-195 were also measured and compared by a real-time polymerase chain reaction. RESULTS: There was a significant increase in TNF-α (p=0.006), IL-1ß (p=0.012), and IL-6 (p=0.012) levels in the AD subjects compared with controls. Also, we found a decrease in plasma levels of klotho and an increase in plasma levels of DPP4 in the AD group that was not significant compared with the controls. Lower expression of miR-29a (P=0.009) and higher expression of miR-195 (P=0.003) were observed in the AD group that was significant than controls. Further analysis showed a negative correlation between klotho and plasma levels of IL-6 (r=-0.58, p=0.01). Also, there was a positive correlation between plasma DPP4 activity and TNF-α levels (r=0.50, P=0.04) and IL-1ß (r=0.62, P=0.01). Likewise, plasma klotho concentration showed a negative correlation with the age of AD subjects (r=-0.56, P=0.02). CONCLUSION: TNF-α, IL-1ß, and IL-6 are involved in AD pathophysiology, and dysregulation of DPP4 and klotho may be associated with the inflammatory response of AD. Down-regulation of miR-29a and up-regulation of miR-195 indicated the role of miRNAs in the AD process.

Comparative Outcomes of Primary Arterial Switch Operation for Transposition of Great Arteries within the First Month of Life.

Background: The optimal surgical plan to correct the simple transposition of the great arteries (TGA) is the arterial switch operation (ASO). This study aimed to assess the outcomes of ASO in infants with simple TGA with a special focus on the time of surgery. Methods: This retrospective study enrolled 105 infants with simple TGA who underwent ASO and categorized them into 3 groups based on the time of repair: first week of life: Group A; second week of life: Group B; and third week of life: Group C. The endpoints, comprised of an assessment of pre- and postoperative outcomes, complications, and survival, were compared between the groups. Results: The mean age of the infants was 10.50±6.26 days, and 61 (58.1%) cases were male. The mean number of days on dopamine was 1.85±0.12 in Group A, 2.48±0.03 in Group B, and 2.67±0.08 in Group C (P<0.001). The mean number of days on epinephrine was 1.25±0.07 in Group B and 1.27±0.08 in Group C (P<0.001). The mean number of days on the ventilator was 3.52±0.20 in Group A, 4.56±0.24 in Group B, and 5.06±0.21 in Group C (P<0.001). The mean number of days of ICU stay was 6.69±0.21 in Group A, 8.46±0.57 in Group B, and 9.70±0.64 in Group C (P<0.001). The infants in Group A had a greater survival rate (97.0%) than those in Group B (94.1%) and Group C (78.4%) (P=0.042). Conclusion: ASO in infants with simple TGA can be done within the first week of life with satisfactory outcomes and survival.

Early mobilization reduces delirium after coronary artery bypass graft surgery.

BACKGROUND: Postoperative delirium is common in patients undergoing coronary artery bypass grafting, characterized by cognitive decline. This study aimed to evaluate the effect of early planned mobilization on delirium after coronary artery bypass grafting. METHODS: This double-blind randomized clinical trial enrolled 92 consecutive patients who underwent coronary artery bypass grafting from September to December 2018. The patients were divided into two groups of 46: a mobilization protocol was applied in the intervention group in the first 2 days after surgery; the control group received routine nursing care only. Demographic data, medical records, and Neecham confusion scores were analyzed. RESULTS: Patients in the control group used cigarettes (31.1% vs. 11.1%, p = 0.020) and opium poppy for recreation (35.6% vs. 8.9%, p = 0.002) more frequently, had longer intubation times (11.91 ± 3.87 vs. 10.23 ± 2.71 h, p = 0.020), and fewer blood components infused (15.6% vs. 33.3%, p = 0.05). More patients in the intervention group had normal function on the 2nd postoperative day compared to the control group (25 vs. 2, respectively, p = 0.001). The intervention group had significantly higher Neecham scores on postoperative day 2 (22.49 ± 2.03 vs. 26.82 ± 2.10, p = 0.001). Multivariable analysis showed significant associations between Neecham score and age (p = 0.022), ejection fraction (p = 0.015), myocardial infarction (p = 0.016), systolic pressure (p = 0.009), and diastolic pressure (p = 0.008). CONCLUSIONS: Early planned mobilization was effective in reducing postoperative delirium in patients undergoing coronary artery bypass grafting.
