Lumbar Puncture in the prone position for Low Birth Weight Neonates.

BACKGROUND: Lumbar puncture in the lateral decubitus position will make the neonates uncomfortable and is likely to cause position change and unstable vital signs, and the application of sedative drugs will cause adverse effects. This study explored a novel method for lumbar puncture in the prone position for low weight neonates. METHODS: The neonates were randomly assigned into the standard position group receiving lumbar puncture in the lateral decubitus position; and the improved position group receiving lumbar puncture in the prone position. The success rate of first time attempts and the overall success rate of lumbar puncture, incidence of adverse effects, NIAPAS scores were collected and compared between these two groups. The difference in success rate and adverse effects incidence rate was analysed through Chi-square. Student's t-test was used for the test of NIAPAS rating. RESULTS: The improved position group had a higher success rate of first attempt and overall success rate, significantly lower incidence of adverse effect and lower NIAPAS scores than those of the standard position group (P<0.05). CONCLUSION: This lumbar puncture in the prone position is safer, more effective, and more comfortable for preterm neonates and those with low birth weight. Thus, this method is worth of further promotion. TRIAL REGISTRATION: Registration number, ChiCTR2100049923; Date of Registration, August 11, 2021; Retrospectively registered.

A case of 10 year follow-up after transcatheter closure of a traumatic ventricular septal defect.

Ventricular septal defect (VSD) is an uncommon complication of penetrating heart injuries, but transcatheter closure has emerged as a new technique and is widely used worldwide. In spite of high success rate and minimal operative mortality, short-term follow-up post-operation and long-term follow-up post-operation have not been observed. In the present study, we report a case of cardiac injury after stabbing himself with a dagger. The patient was diagnosed with a post-traumatic VSD with left-to-right shunt and was transferred to theatre where the defect was successfully repaired. Seven days later, on echocardiography examination, an occluder closing the defect with no residual leak was revealed. During the extensive follow-up over 10 years, no complication of occluder break, translocation and thrombosis formation occurred.

Mid- to long-term follow-up of pediatric patients with coronary artery fistula.

BACKGROUND/PURPOSE: To investigate mid- to long-term outcomes in children with coronary artery fistula (CAF). METHODS: We retrospectively reviewed the medical records of patients seen between September 1996 and August 2011. We enrolled those diagnosed with CAF via echocardiography (Philips SONOS 7500 system and Philips IE33) or angiography. The mean follow time was 42.58 ± 3.4 months (range, 1-166 months). For comparative purposes, participants were grouped as acquired versus congenital, and symptomatic versus asymptomatic. We also measured the size of the coronary artery (CA) in patients with CA dilatation (CAD). RESULTS: Out of 122 CAF patients, spontaneous closure was detected in 37 patients at 21.59 ± 3.45 months after diagnosis. This timeframe did not differ between the acquired and congenital groups (21.64 ± 6.26 months vs. 21.57 ± 4.15 months; p = 0.991). Ninety patients were asymptomatic and remained so; their spontaneous closure rate was 28.89%. Moreover, 24 patients had CAD, including 17 with Kawasaki disease and seven with congenital CAF. The CAs of all congenital-CAF-plus-CAD patients were initially > 5 mm; these patients underwent percutaneous transcatheter intervention, and their CA sizes decreased significantly (6.11 ± 0.79 mm vs. 3.76 ± 0.36 mm; p = 0.002). CONCLUSION: With the advanced sensitivity of echocardiography, CAF can be detected more easily than ever before. Most patients with small CAFs are asymptomatic and may experience spontaneous closure. Therefore, management of CAF depends on symptoms; if patients are asymptomatic and have small CAFs, intervention may not be necessary, especially in acquired cases. However, if patients present with symptoms or persistent dilatation of the proximal CA, surgical or percutaneous closure should be performed.

Tricuspid regurgitation in acute phase of Kawasaki disease associated with intensive care unit admission.

Kawasaki disease (KD) is a systemic vasculitis and primarily affects children <5 years of age. Intensive care unit (ICU) admission is unusual, but there can be associated severe complications in KD patients. This study was conducted to identify risk factors for ICU admission. Retrospectively, we reviewed charts of all children who had a discharge diagnosis of KD from 2001 through 2009. Clinical presentation, laboratory data, and outcome were collected for analysis of the association with ICU admission in KD patients. Multifactor dimensionality reduction (MDR) was used to identify factor interactions. There were 334 KD patients, including 24 patients in ICU admission, included in the analysis. Coronary artery lesions (CALs) and failure of intravenous immunoglobulin (IVIG) treatment were more frequently found in the ICU group (P < 0.0001). Total counts of white blood cells, hemoglobin levels, C-reactive protein, and albumin levels showed significant association with ICU admission (P < 0.05). Moderate tricuspid regurgitation (TR) was found only in the ICU admission group. MDR analyses of factor interactions identified that TR interacted with CAL with a prediction accuracy of 77.78 %. (P = 0.001). Patients with KD who are IVIG resistant and/or who are found to have CALs are at increased risk for ICU admission. Most importantly, moderate TR was significantly found in KD patients only in the ICU group. This may highlight the great value of moderate TR in predicting ICU admission for patients with KD.

Small-bore pigtail catheters for the treatment of primary spontaneous pneumothorax in young adolescents.

OBJECTIVE: Small-bore pigtail catheters have been found to be effective in the treatment of primary spontaneous pneumothorax (PSP) in adults. The aim of this study was to compare the effectiveness of small-bore pigtail and large-bore catheters in the treatment of PSP in young adolescents. MATERIALS AND METHODS: Young adolescents (<18 years) with initial PSP were treated with aspiration (control group), small-bore pigtail catheters or large-bore catheters. Treatment was determined on a case-by-case basis with parental consultation. Success rate, recurrence rate (within 12 months), duration of hospital stay, duration of catheter insertion, and complications were analysed. MAIN RESULTS: There were 41 patients treated: aspiration, n=8; small-bore pigtail catheters, n=10; large-bore catheters, n=23. Demographic and baseline clinical characteristics were similar between groups. The success rates were 50.0% and 65.2% in the small-bore pigtail and large-bore catheter groups, respectively. Corresponding recurrence rates were 20.0% and 56.5%. There was no difference between the small-bore pigtail and large-bore catheter groups in the duration of hospital stay in patients for whom treatment was successful; however, the duration of catheter insertion was significantly shorter in the small-bore pigtail catheter group compared with the large-bore catheter group in patients for whom treatment was successful (p<0.05). There were no major complications in either catheter treatment group and few minor complications (small-bore pigtail catheter, n=2; large-bore catheter, n=4). CONCLUSIONS: The findings suggest that small-bore pigtail catheters may be as effective as large-bore catheters for the initial treatment of PSP in young adolescents.

Predictors for Regression of Large Secundum Atrial Septal Defects Diagnosed in Infancy.

PUPOSE: To determine predictive factors of spontaneous closure or size reduction in large secundum-type atrial septal defects (ASD) diagnosed in infancy prior to catheterization or surgical intervention. METHODS: From June 2003 to October 2009, 59 infants diagnosed with secundum-type ASDs measuring ≥ 8 mm in the first year of life were retrospectively enrolled. We reviewed medical records, as well as electrocardiography and echocardiography findings. Patients were divided into 2 groups according to the last ASD size: group A (n = 23), ASD reduction in size to < 5 mm or spontaneous closure; group B (n = 36), size of ASD remained ≥ 5 mm. RESULTS: The ASDs spontaneously closed in 10 (17%) patients at a median age of 26.0 ± 5.1 months (range, 15-58 months), or decreased to < 5 mm in 13 (22%) (range, 6-27 months) patients. There was a significant difference in age at diagnosis between the 2 groups (p = 0.014). Patients in group A were younger than those in group B at the time of diagnosis. Changes in ASD size (p < 0.001) and body weight percentile (p = 0.01) were also significantly different fromthe 6-month follow-up. ASD diameter of ≥ 10 mm was a negative predictive factor for size reduction (p = 0.017). CONCLUSIONS: Spontaneous closure or size reduction of large ASDs was not uncommon in patients diagnosed during infancy. Patients with initial ASD sizes between 8 and 10 mm who were younger at the time of diagnosis and showed better weight gain were more likely to have favorable outcomes. KEY WORDS: Infancy; Large secundum atrial septal defect; Natural course; Spontaneous closure.

Lack of association between CLEC5A gene single-nucleotide polymorphisms and Kawasaki disease in Taiwanese children.

BACKGROUND: Kawasaki disease is characterized by systemic vasculitis of unknown etiology. Previous genetic studies have identified certain candidate genes associated with susceptibility to KD and coronary artery lesions. Host innate immune response factors are involved in modulating the disease outcome. The aim of this study was to investigate CLEC5A (C-type lectin domain family 5) genetic polymorphisms with regards to the susceptibility and outcome of KD. METHODS: A total of 1045 subjects (381 KD patients and 664 controls) were enrolled to identify 4 tagging single-nucleotide polymorphisms (tSNPs) of CLEC5A (rs1285968, rs11770855, rs1285935, rs1285933) by using the TaqMan Allelic Discrimination Assay. The Hardy-Weinberg equilibrium was assessed in cases and controls, and genetic effects were evaluated by the chi-square test. RESULTS: No significant associations were noted between the genotypes and allele frequency of the 4 CLEC5A tSNPs between controls and patients. In the patients, polymorphisms of CLEC5A showed no significant association with coronary artery lesion formation and intravenous immunoglobulin treatment response. CONCLUSIONS: This study showed for the first time that polymorphisms of CLEC5A are not associated with susceptibility to KD, coronary artery lesion formation, and intravenous immunoglobulin treatment response in a Taiwanese population.

Monoarticular septic arthritis in a patient with juvenile rheumatoid arthritis under etanercept treatment.

A 7-year-old girl with polyarticular type juvenile rheumatoid arthritis (JRA) presented with acute onset of right hip pain with limited range of motion and fever within the past two days. She had received etanercept for more than one year. Percutaneous arthrocentesis was performed and showed a white blood cell count of 84150/µL in the synovial fluid, although the culture showed negative results. The fever and right hip pain completely resolved after antibiotic treatment. Herein, we report the first case of septic monoarthritis of JRA under etanercept treatment.

The impact of intrapulmonary shunting after liver transplantation in pediatric patients.

BACKGROUND/PURPOSE: Intrapulmonary shunting (IPS) due to pulmonary vascular dilatation is frequently observed among patients with end-stage liver disease (ESLD). This study investigated the prevalence and impact of IPS after liver transplantation (LT) in children. METHODS: A total of 77 pediatric patients who underwent primary LT were enrolled. All patients had trans-thoracic contrast echocardiography before LT and at least 1 year after transplantation. The patients with IPS and without IPS after LT were designated as group 1 and group 2, respectively. RESULTS: The prevalence of IPS after LT was 6.1%. The patients in group 1 (n=5) were younger (6.4 +/- 2.8 vs. 9.9 +/- 3.6, p=0.036) than in group 2 (n=72). There were no significant differences in gender, weight, hemoglobin level, O(2) saturation, or complications between the two groups. Fourteen patients had abnormal liver function tests, two patients in group 1 and 12 patients in group 2 (p=0.22).The overall follow-up period was 6.7 +/- 2.7 years (range, 1.6-13.0). At the latest follow-up, all 5 patients with mild IPS after LT remain asymptomatic with good liver graft function. CONCLUSION: Among pediatric ESLD patients with preoperative IPS, approximately 6% continue to have mild IPS after LT. Patients with mild IPS after LT remain asymptomatic and have good liver graft function.

CD40 Gene polymorphisms associated with susceptibility and coronary artery lesions of Kawasaki disease in the Taiwanese population.

BACKGROUND: Kawasaki disease (KD) is characterized by systemic vasculitis of unknown etiology. Our previous studies showed expression of CD40 ligand on CD4+ T cells correlated to the coronary artery lesion (CAL) and disease progress in KD. Other studies from Japan suggested the role of CD40L in the pathogenesis of CAL, and this might help explain the excessive number of males affected with KD but cannot be reproduced by Taiwanese population. This study was conducted to investigate the CD40 polymorphism in KD and CAL formation. METHODS: A total of 950 subjects (381 KD patients and 569 controls) were investigated to identify 2 tagging single-nucleotide polymorphisms (tSNPs) of CD40 (rs4810485 and rs1535045) by using the TaqMan allelic discrimination assay. RESULTS: A significant association was noted with regards to CD40 tSNPs (rs1535045) between controls and KD patients (P = 0.0405, dominant model). In KD patients, polymorphisms of CD40 (rs4810485) showed significant association with CAL formation (P = 0.0436, recessive model). Haplotype analysis did not yield more significant results between polymorphisms of CD40 and susceptibility/disease activity of KD. CONCLUSIONS: This study showed for the first time that polymorphisms of CD40 are associated with susceptibility to KD and CAL formation, in the Taiwanese population.

DC-SIGN (CD209) promoter -336 A/G (rs4804803) polymorphism associated with susceptibility of Kawasaki disease.

Kawasaki disease (KD) is characterized by systemic vasculitis of unknown etiology. High-dose intravenous immunoglobulin (IVIG) is the most effective therapy for KD to reduce the prevalence of coronary artery lesion (CAL) formation. Recently, the α2, 6 sialylated IgG was reported to interact with a lectin receptor, specific intracellular adhesion molecule-3 grabbing nonintegrin homolog-related 1 (SIGN-R1) in mice and dendritic cell-specific intercellular adhesion molecule-3 grabbing nonintegrin (DC-SIGN) in human, and to trigger an anti-inflammatory cascade. This study was conducted to investigate whether the polymorphism of DC-SIGN (CD209) promoter -336 A/G (rs4804803) is responsible for susceptibility and CAL formation in KD patients using Custom TaqMan SNP Genotyping Assays. A total of 521 subjects (278 KD patients and 243 controls) were investigated to identify an SNP of rs4804803, and they were studied and showed a significant association between the genotypes and allele frequency of rs4804803 in control subjects and KD patients (P = 0.004 under the dominant model). However, the promoter variant of DC-SIGN gene was not associated with the occurrence of IVIG resistance, CAL formation in KD. The G allele of DC-SIGN promoter -336 (rs4804803) is a risk allele in the development of KD.

Serum Fibroblast Growth Factor 21 Level Is Associated with Aortic Stiffness in Patients on Maintenance Hemodialysis.

BACKGROUND: Fibroblast growth factor 21 (FGF-21) is a hormone that regulates glucose and lipid metabolism. High serum FGF-21 levels are associated with carotid atherosclerosis and coronary artery disease. This cross-sectional study aimed to assess the relationship between serum FGF-21 levels and carotid-femoral pulse wave velocity (cfPWV) in patients on maintenance hemodialysis (HD). METHODS: Blood samples and baseline characteristics were collected from 130 HD patients. Serum FGF-21 concentrations were measured with an enzyme-linked immunosorbent assay kit. Aortic stiffness was defined as a carotid-femoral pulse wave velocity (cfPWV) of more than 10 m/s. RESULTS: Of the 130 HD patients, aortic stiffness was diagnosed in 54 (41.5%). Serum FGF-21 levels were significantly higher in those with aortic stiffness than those without (P < 0.001). The FGF-21 level was independently associated with aortic stiffness (odds ratio (OR): 1.008; 95% CI: 1.003-1.012; P=0.001) after adjusting for diabetes mellitus, age, hypertension, C-reactive protein, and body weight in multivariable logistic regression analysis. Multivariable forward stepwise linear regression analysis also confirmed that the logarithmically transformed FGF-21 level (ß = 3.245, 95% CI: 1.593-4.987, P < 0.001) was an independent predictor of cfPWV values. The area under the receiver operating characteristic (ROC) curve predicting aortic stiffness by the serum FGF-21 level was 0.693 (95% CI: 0.606-0.771, P < 0.001). CONCLUSIONS: Serum FGF-21 level positively correlates with cfPWV and is also an independent predictor of aortic stiffness in maintenance HD patients.

CTLA-4, position 49 A/G polymorphism associated with coronary artery lesions in Kawasaki disease.

OBJECTIVE: Kawasaki disease (KD) is a systemic vasculitis of unknown etiology and primarily affects children less than 5 years of age. Cytotoxic T lymphocyte-associated antigen-4 (CTLA-4) has been suggested as a candidate gene for conferring susceptibility to autoimmunity. This study examined the correlation of CTLA-4 gene polymorphisms in KD with and without coronary artery lesions (CAL). MATERIALS AND METHODS: A total of 233 KD patients and 644 controls were subjected to determination of CTLA-4 polymorphisms at (-318) C/T and (+49) A/G positions by restriction fragment length polymorphism. Susceptibility, CAL, and intravenous immunoglobulin treatment response of KD were then analyzed with genetic variants. RESULTS: Polymorphisms of CTLA-4 (+49 A/G) and (-318 C/T) were not significantly different between normal children and patients with KD. The CTLA-4 (+49) A allele (AA+AG genotype), however, was significantly associated with CAL formation, especially in female patients. CONCLUSIONS: This study provides the first evidence supporting the association of CTLA-4 (+49) A/G polymorphism with the CAL formation of KD particularly in female patients.

Lack of association between ORAI1/CRACM1 gene polymorphisms and Kawasaki disease in the Taiwanese children.

OBJECTIVE: Kawasaki disease (KD) is characterized by systemic vasculitis of an unknown cause. A previous study has indicated that a polymorphism of the inositol 1,4,5-trisphosphate 3-kinase C (ITPKC) gene is involved in the susceptibility to KD. ORAI (also known as CRACM1) is one of the components of store-operated calcium channels involved in regulating immune and inflammatory reactions. This study was conducted to investigate if polymorphisms in ORAI1/CRACM1, a gene downstream from ITPKC, are associated with KD susceptibility and clinical outcomes. MATERIALS AND METHODS: A total of 1,056 subjects (341 KD patients and 715 controls) were investigated to identify five tagging single nucleotide polymorphisms (tSNPs) in ORAI1/CRACM1 (rs12313273, rs6486795, rs7135617, rs12320939, and rs712853) by using the TaqMan Allelic Discrimination assay. RESULTS: No significant associations between genotype and allele frequency of the five ORAI1/CRACM1 tSNPs were observed in the KD patients and controls. In KD patients, no significant associations between ORAI1/CRACM1 polymorphisms and coronary artery lesion (CAL) formation or intravenous immunoglobulin (IVIG) treatment response were observed. The results from haplotype analysis were insignificant. CONCLUSIONS: This study showed for the first time that ORAI1/CRACM1 polymorphisms are not associated with KD susceptibility, CAL formation, or IVIG treatment response in the Taiwanese population.

CASP3 gene single-nucleotide polymorphism (rs72689236) and Kawasaki disease in Taiwanese children.

Kawasaki disease (KD) is characterized by systemic vasculitis of unknown etiology. A study from Japan reported that G to A substitution of a single-nucleotide polymorphism (SNP) located in the 5'-untranslated region of caspase 3 (CASP3) (rs72689236), which was associated with nuclear factor of activated T cell-mediated T-cell activation, is responsible for susceptibility to KD. This study was conducted to investigate whether the polymorphism of CASP3 is responsible for susceptibility and coronary artery lesion (CAL) formation in KD in the Taiwanese population. A total of 1092 subjects (341 KD patients and 751 controls) were investigated to identify an SNP of rs72689236 using Invader assays (Third Wave Technologies). Our data provided a borderline significant association between the genotypes and allele frequency of rs72689236 in control subjects and KD patients (P=0.0535 under the dominant model; P=0.0575 under the allelic model). The A allele of rs72689236 in KD patients and in patients with CAL and intravenous immunoglobulin resistance was seen in a higher frequency. Importantly, a significant association was obtained between rs72689236 and KD patients with aneurysm formation (P=0.009, under the recessive model). The A allele of rs72689236 is very likely to be a risk allele in the development of aneurysm in patients with KD.

Glyceraldehyde-3-phosphate dehydrogenase is a reliable internal control in Western blot analysis of leukocyte subpopulations from children.

To study differences in the development of immunity, leukocytes from cord blood are often compared with those from adult peripheral blood. Western blot analysis is a common method for detecting proteins. In this study, we investigated the reliability of using different housekeeping proteins (ß-actin, ß-tubulin, and glyceraldehyde-3-phosphate dehydrogenase [GAPDH]) as internal controls for different leukocyte subpopulations from infants, children, and adults. Our results showed that the expression levels of ß-actin and ß-tubulin were much lower in cord blood leukocytes than in adult leukocytes, and this expression pattern persisted in children up to 3 years old. Further study revealed that the ß-actin expression level in newborns was especially lower in CD14-positive monocytes. However, cord blood and adult peripheral blood monocytes had similar expression levels of ß-actin messenger RNA (mRNA). Further experiments showed that posttranslational regulation was responsible for the low ß-actin expression level in neonatal monocytes. Thus, researchers should carefully assess the appropriate use of housekeeping gene-encoded proteins as internal standards to normalize samples for comparisons of different leukocyte populations from subjects of different ages. In this study, we determined that GAPDH was a more reliable internal control than others in Western blot analysis for comparing the development of immunity among infants, children, and adults.

Impact of transcatheter closure of atrial septal defects in pediatric patients on body weight.

BACKGROUND/PURPOSE: Pediatric patients with atrial septal defect (ASD) may have failure to thrive. This study aimed to investigate body weight changes in pediatric patients after transcatheter closure of ASD. METHODS: From June 2003 to September 2008, we enrolled 60 pediatric patients who underwent transcatheter closure of ASD. Changes in body weight percentile, heart rate, and resolution of right ventricular hypertrophy were compared before and after ASD closure. Patients were divided into two groups according to initial weight percentile: group A, <50(th) percentile (n = 39) and group B, ≥50(th) percentile (n = 21). Echocardiography and routine weight measurements were performed before the procedure and at 3, 6, and 12 months during follow-up. Clinical presentations, laboratory data, and outcomes were measured. RESULTS: Increased body weight percentile (41±4 vs. 48±4, p<0.01), lower heart rate (100±2 beats/min vs. 89±2beats/min, p<0.01), and resolution of right ventricular hypertrophy (59/60 vs. 1/60, p<0.01) were achieved after ASD closure at the 12-month follow-up. Patients in group A were significantly younger (4.6±0.5 years vs. 7.0±0.9 years, p = 0.016), had a higher pulmonary/systemic blood flow ratio (2.2±0.1 vs. 1.8±0.l, p = 0.044), a largerratio of ASD diameter/body surface area (25.0±1.4 vs. 16.4±1.9, p<0.01), and higher percentage of weight gain increase ≥ 5 percentile compared with patients in group B (22/39 vs. 6/21, p = 0.039). CONCLUSION: Transcatheter closure of ASD positively affects weight gain. An increase of 7 percentile weight was observed at 1 year of follow-up. Patients with a younger age, higher pulmonary/systemic blood flow ratio, and a larger ratio of ASD diameter/body surface area may have better weight gain after ASD closure.

Role of NEAT1/MiR-9-5p/SLC26A2 Pathway on Human Airway Smooth Muscle Cell.

PURPOSE: Asthma is a serious inflammatory disease of the respiratory system in which airway smooth muscle cells (ASMCs) play a key role. This study aimed to investigate the expression of SLC26A2 in human ASMCs (HASMCs) and the regulatory mechanism of SLC26A2 in the proliferation and inflammatory factor production of HASMCs. MATERIALS AND METHODS: We obtained the asthma-associated differential mRNA SLC26A2 by bioinformatics analysis in childhood acute asthma samples. To investigate its role in airway inflammation and airway remodeling, we treated HASMCs with platelet-derived growth factor (PDGF) in an in vitro model and determined SLC26A2 expression in cells using western blotting. Cell proliferation was detected by MTT and EdU assays, and cell contractile phenotype marker proteins were measured. Cell migration and production of inflammatory factors were determined by Transwell and ELISA assays. Additionally, the upstream regulatory miRNA and LncRNA of SLC26A2 were identified by bioinformatics, luciferase reporter gene, and RIP analyses. RESULTS: SLC26A2 was significantly upregulated in bioinformatics analysis of pediatric asthma-related sample. PDGF treatment up-regulated SLC26A2 expression in HASMCs, whereas the knockdown of SLC26A2 inhibited PDGF-stimulated proliferation, migration, and production of inflammatory factors, and enhanced the expression of cell contractile phenotype marker proteins in HASMCs. Luciferase reporter and RIP experiments validated that NEAT1 targeted miR-9-5p to regulate SLC26A2, thereby influencing the biological function of PDGF-induced HASMCs. CONCLUSION: These findings indicate that NEAT1-mediated miR-9-5p targeting of SLC26A2 inhibits the PDGF-induced proliferation and production of inflammatory factors in HASMCs. These findings highlight potential therapeutic targets for asthma and airway inflammation.

Polypharmacy Is Significantly and Positively Associated with the Frailty Status Assessed Using the 5-Item FRAIL Scale, Cardiovascular Health Phenotypic Classification of Frailty Index, and Study of Osteoporotic Fractures Scale.

The aim of this study was to investigate the association between frailty and polypharmacy using three different frailty screening tools. This was a cross-sectional study of people aged ≥65 years. Participants were included and interviewed using questionnaires. Polypharmacy was defined as the daily use of eight or more pills. Frailty was assessed using a screening tool, including (1) the Fatigue, Resistance, Ambulation, Illness and Loss of Weight Index (5-item FRAIL scale), (2) the Cardiovascular Health Phenotypic Classification of Frailty (CHS_PCF) index (Fried's Frailty Phenotype), and (3) the Study of Osteoporotic Fracture (SOF) scale. A total of 205 participants (mean age: 71.1 years; 53.7% female) fulfilled our inclusion criteria. The proportion of patients with polypharmacy was 14.1%. After adjustments were made for comorbidity or potential confounders, polypharmacy was associated with frailty on the 5-item FRAIL scale (adjusted odds ratio [aOR]: 9.12; 95% confidence interval [CI]: 3.6-23.16), CHS_PCF index (aOR: 8.98; 95% CI: 2.51-32.11), and SOF scale (aOR: 6.10; 95% CI: 1.47-25.3). Polypharmacy was associated with frailty using three frailty screening tools. Future research is required to further enhance our understanding of the risk of frailty among older adults.

Absent pulmonary valve syndrome with ascending aortic aneurysm.

Absent pulmonary valve syndrome is rare. We report the case of a child with absent pulmonary valve syndrome noted after birth. Progressive dilatation of the main pulmonary artery and ascending aorta were noted by echocardiography and confirmed by heart computed tomography. He underwent ascending aorta graft replacement and pulmonary artery reduction angioplasty at the age of 6. Good outcome was achieved at 18-month follow-up where subsequent computed tomography revealed a normal size ascending aorta and main pulmonary artery.
