Comparison of Diagnostic Accuracy and Diagnostic Adequacy Between Endoscopic Ultrasound-Guided and Percutaneous Liver Biopsies: A Meta-Analysis of Randomized Controlled Trials and Observational Studies.

A liver biopsy (LB) is a crucial diagnostic tool for evaluating liver diseases and is traditionally performed percutaneously under ultrasound guidance (PC-LB). However, endoscopic ultrasound-guided liver biopsy (EUS-LB) has emerged as an alternative approach, offering potential advantages over conventional techniques. This systematic review and meta-analysis aimed to compare the effectiveness and safety of EUS-LB using modern core biopsy needles with PC-LB. A comprehensive literature search identified nine studies involving 785 patients that met the inclusion criteria. The meta-analysis evaluated three primary endpoints: diagnostic adequacy, diagnostic accuracy, and adverse event rates. The results indicated no significant difference in overall diagnostic adequacy (odds ratio: 0.446, 95% CI: 0.192-1.031) or diagnostic accuracy (odds ratio: 1.646, 95% CI: 0.224-12.09) between EUS-LB and PC-LB. Furthermore, the combined occurrence of adverse events did not differ significantly between the two procedures (odds ratio: 0.653, 95% CI: 0.298-1.431). However, PC-LB demonstrated superiority in obtaining a higher number of complete portal tracts (mean difference: -0.985, 95% CI: -1.753 to -0.218), indicating better specimen quality. While both EUS-LB and PC-LB exhibited similar diagnostic performance and safety profiles, PC-LB provided higher-quality specimens, which may be advantageous in cases where accurate diagnosis and staging are critical, such as the evaluation of liver fibrosis. Clinicians should consider factors like specimen quality, procedural preferences, and local expertise when selecting the appropriate biopsy approach tailored to individual patient needs and clinical circumstances.

Comparison of the Effectiveness and Safety of Metoprolol and Diltiazem in Atrial Fibrillation With Rapid Ventricular Rate Patients: A Systematic Review and Meta-Analysis.

This study aims to assess the association between intravenous diltiazem and metoprolol in rate control for atrial fibrillation (AF) patients with rapid ventricular rate, focusing on rate control efficacy and hemodynamic adverse events. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, electronic searches were conducted in Embase, PubMed, and Cochrane Central Register of Controlled Trials (CENTRAL) until February 20, 2024. The primary outcome was achieving ventricular rate control < 110/min. Secondary outcomes included new hypotension (systolic blood pressure < 90 mm Hg) and bradycardia (heart rate < 60/min). Nineteen studies (three randomized controlled trials and 16 observational studies) were included in this meta-analysis. Pooled analysis showed intravenous metoprolol resulted in a 39% lower rate control attainment compared to diltiazem (OR: 0.61; 95% CI: 0.44 to 0.84; p = 0.002). There were no significant differences in bradycardia (OR: 0.51; 95% CI: 0.22 to 1.22; p = 0.13) or hypotension risk (OR: 1.08; 95% CI: 0.72 to 1.61; p = 0.72) between the two groups. Intravenous diltiazem demonstrated superior rate control efficacy compared to metoprolol in AF patients with rapid ventricular rate. However, no significant differences were observed in safety outcomes, namely, bradycardia and hypotension.

Risk Factors for the Development of Pneumonia in Stroke Patients: A Systematic Review and Meta-Analysis.

Pneumonia is one of the most prevalent medical complications post-stroke. It can have negative impacts on the prognosis of stroke patients. This study aimed to determine the predictors of pneumonia in stroke patients. The authors devised, reviewed, and enhanced the search strategy in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Studies were gathered from various electronic databases, including Medline, CINAHL, Cochrane, Embase, and Web of Science, from January 1st, 2011, to February 25th, 2024. The review encompassed studies involving patients aged 18 years and older who were hospitalized for acute stroke care. Inclusion criteria required patients to have received a clinical diagnosis of stroke, confirmed via medical imaging (CT or MRI), hospital primary diagnosis International Classification of Diseases 10th Revision discharge codes, or pathology reporting. A total of 35 studies met the criteria and were included in our pooled analysis. Among them, 23 adopted a retrospective design, while the remaining 12 were prospective. The pooled incidence of pneumonia among patients with stroke was found to be 14% (95% confidence interval = 13%-15%). The pooled analysis reported that advancing age, male gender, a history of chronic obstructive pulmonary disease (COPD), the presence of a nasogastric tube, atrial fibrillation, mechanical ventilation, stroke severity, dysphagia, and a history of diabetes were identified as significant risk factors for pneumonia development among stroke patients. Our results underscore the importance of proactive identification and management of these factors to mitigate the risk of pneumonia in stroke patients.

Assessment of Oral Health-Related Quality of Life Using the Oral Impact on Daily Performance (OIDP) Instrument Among Secondary School Teachers of Modinagar, Uttar Pradesh: A Cross-Sectional Study.

Introduction Oral health has an impact on a person's general health, well-being, and quality of life. Due to their expertise and interactions with people, school staff members can actively contribute to the promotion of children's health if provided with the proper training. Methodology A cross-sectional survey was conducted to assess the "oral health-related quality of life" using the Oral Impact on Daily Performance (OIDP) instrument among the secondary school teachers of Modinagar, Uttar Pradesh. The study included a sample of 400 government secondary school teachers and 400 private secondary school teachers. The independent sample t-test was performed to assess the relationship between the mean of OIDP dimensions and the prevalence of dental caries. Any p-value less than 0.05 was considered significant. The data was analyzed using the SPSS version 20.0 software package (IBM Corp., Armonk, NY). Results In the present study, most of the participants (174 (43.5%) government teachers and 197 (49.2%) private teachers) were in the age group of 41-50 years. According to the Decayed, Missing, and Filled Teeth (DMFT) index, the mean decayed teeth present for government and private school teachers were 0.45 ± 0.503 and 0.41 ± 0.493, respectively, and the mean DMF scores for government and private teachers were 1.27 ± 0.736 and 1.03 ± 0.757, respectively. There was a positive correlation between the DMFT scores and the mean scores for the dimensions of the OIDP among both government and private secondary school teachers. Conclusion The poor dental health status of teachers' has a bad impact on everyday performance and academic work. The findings of the study highlight the need for oral health education and good oral health maintenance among school teachers since they are the ones who can easily influence the behavior of the children.

Racial disparities in women with ST elevation myocardial infarction: A National Inpatient Sample review of baseline characteristics, co-morbidities, and outcomes in women with STEMI.

BACKGROUND: A third of the patients admitted with Acute coronary syndrome (ACS) have ST-elevation myocardial infarction (STEMI). Previous studies showed that females with STEMI have higher mortality than men. HYPOTHESIS: There exist significant disparities in outcomes among women of different races presenting with STEMI. METHODS: National inpatient sample (NIS) data was obtained from January 2016 to December 2018 for the hospitalization of female patients with STEMI. We compared outcomes, using an extensive multivariate regression analysis amongst women from different races. Our primary outcome was in-hospital mortality. Secondary outcomes were revascularization use, procedure complications, and healthcare utilization. RESULTS: Of 202 223 female patients with STEMI; 11.3% were African American, 7.4% Hispanic, 2.4% Asian, and 4.3% another race. In-hospital mortality was higher in non-Caucasian groups. African American (adjusted odds ratio [aOR] 1.2; 95% confidence interval [CI]: 1.07-1.30; p < .01) and another race (aOR 1.37; 95% CI: 1.15-1.63; p < .01) had higher odds of mortality when compared with white women. African American (aOR 0.69; 95% CI: 0.62-0.72; p < .01), Hispanics (aOR 0.81; 95% CI: 0.74-0.88; p < .01), and Asian (aOR 0.79; 95% CI: 0.69-0.90; p < .01) had lower odds of percutaneous intervention (PCI) when compared with whites. African Americans had fewer odds of Coronary Artery Bypass Graft (CABG) and use of Mechanical Circulatory Support (MCS) during the index admission. Non-Caucasians had more comorbidities, complications, and healthcare utilization costs. CONCLUSION: There are significant racial disparities in clinical outcomes and revascularization in female patients with STEMI. African American women have a higher likelihood of mortality among the different races. Females from minority groups are also less likely to undergo PCI.

Association Between Pulmonary Hypertension and Its Effect on 30-Day Mortality, Readmission, and Cost After Transcatheter Aortic Valve Replacement: A Multicenter Study.

Background Pulmonary hypertension (PH) is commonly seen in patients with severe aortic stenosis. Transcatheter aortic valve replacement (TAVR) has been shown to improve PH, however, its impact on clinical outcomes and cost remains unclear. Methods We did a multicenter, retrospective analysis of patients undergoing TAVR in our system between December 2012 to November 2020. The initial sample size was 1356. We excluded patients with prior history of heart failure, with a left ventricular ejection fraction of 40% or less, and patients who had active symptoms of heart failure within two weeks of the procedure. Patients were divided into four groups based on their pulmonary pressures, using right ventricular systolic pressure (RVSP) as a surrogate for PH. Groups included patients with normal pulmonary pressures (<35mmHg), mild (35-45mmHg) moderate (46-60mmHg), and severe PH (>60mmHg). Primary outcomes included 30-day mortality and readmission. Secondary outcomes included length of ICU stay and cost of admission. We used Chi-square and T-tests for demographic analysis of categorical continuous variables respectively. Adjusted regression was used for the reliability of correlation between variables. Multivariate analysis was used for final outcomes. Results Final sample size was 474. Average age was 78.9 years (SD: 8.2, 53% Male). Thirty-one percent (n=150) had normal pulmonary pressures, 33% (n=156) had mild PH, 25% (n=122) had moderate and 10% (n=46) had severe PH. Patients with history of hypertension (p-value<0.001), diabetes (p-value<0.001), chronic lung disease (p-value=0.006) and those on supplemental oxygen (p-value=0.046), had significantly higher proportion of patients with moderate and severe PH. We found significantly higher odds of 30-day mortality in patients with severe PH (OR: 6.77, CI: 1.09-41.98: p-value 0.04) compared with normal or mild PH. There was no significant difference in 30-day readmission (p-value=0.859) between the four groups. Cost did not change with severity of PH (Avg: $261,075: p-value=0.810). Patients with severe PH spent a significantly higher number of hours in ICU, compared with the other three groups (Mean: 18.2, p=value <0.001). Conclusions Severe pulmonary hypertension significantly increased the odds of 30-day mortality and ICU stay in TAVR patients. We did not see any significant difference in 30-day readmission and cost of admission, based on PH severity.

A Complex Left Internal Mammary Artery Intervention.

There is a variety of conduits utilized as vascular grafts in coronary artery bypass grafting (CABG). Post-CABG graft rate of failure varies depending on the type of conduit used, with the highest failure rates seen in saphenous vein grafts (SVG). Patency rates of SVG are reported to be about 75% at 12-18 months. Left internal mammary artery (LIMA) grafts have shown higher long-term patency rates when compared to other arterial and venous grafts; however, LIMA occlusions occur, most commonly in the early postoperative period. Percutaneous coronary intervention (PCI) of LIMA graft can be challenging based on the location, the length of the lesion, as well as other factors such as vessel tortuosity. Here we present a case of a complex intervention for osteal and proximal LIMA chronic total occlusion (CTO) in a symptomatic patient. Long stent delivery is usually a challenge in LIMA intervention; however, it was successfully achieved here by placing two overlapping stents. This intervention was also complicated by the tortuosity of the lesion, as well as the difficult cannulation of the left subclavian artery requiring a longer sheath for guide support.

Health(care) matters: where do the transgender individuals of Kashmir situate themselves?

While employing a phenomenological perspective, the present study aimed to explore the varied experiences of transgender individuals in Kashmir, concerning their health-seeking behavior, and the constraints they face while accessing healthcare resources on a day-to-day basis in their life world. Participants were recruited through the purposive and snowball sampling strategies and the sufficiency of sample size was determined by data saturation. Data were collected using face-to-face in-depth interviews and analyzed through Colaizzi's procedure of extracting recurrent themes and their interwoven relationships in qualitative research. Three main themes of awareness and the preferences for healthcare, gender identity and persistent stigmatization in care settings, and intra-community support and the resultant caregiving were prominent. Results of the study revealed that the transgender individuals in Kashmir experience inappropriate health-seeking behaviour primarily due to their unawareness regarding health, diseases and public healthcare programs/schemes, financial constraints, social exclusion, improper support and social stigma. They often prefer treating their health issues, mostly through local pharmacies or patent medicine vendors (PMVs), instead of visiting the medical professionals in the organized sector. Moreover, in many instances, they were also found to delay their decisions to seek care or simply decided to remain far from any medical intervention. As a result, the transgender individuals in Kashmir usually experience underutilization of formal healthcare services, which undermines their right to proper health and well-being.

Effects of Group-I Elements on Output Voltage Generation of ZnO Nanowires Based Nanogenerator; Degradation of Screening Effects by Oxidation of Nanowires.

Here, we report the successful incorporation of group I elements (K, Na, Li) to ZnO nanowires. Three distinct (2, 4, and 6 wt.%) doping concentrations of group I elements have been used to generate high piezoelectric voltage by employing a vertically integrated nanowire generator (VING) structure. X-ray photoelectron spectra (XPS) indicated the seepage of dopants in ZnO nanowires by substitution of Zn. Shallow acceptor levels (LiZn, NaZn, KZn) worked as electron trapping centers for intrinsically n-type ZnO nanowires. Free moving electrons caused a leakage current through the nanowires and depleted their piezoelectric potential. Reverse leakage current is a negative factor for piezoelectric nanogenerators. A reduction in reverse leakage current signifies the rise in output voltage. A gradual rise in output voltage has been witnessed which was in accordance with various doping concentrations. K-doped ZnO nanowires have generated voltages of 0.85 V, 1.48 V, and 1.95 V. For Na-doped ZnO nanowires, the voltages were 1.23 V, 1.73 V, and 2.34 V and the voltages yeilded for Li-doped ZnO nanowires were 1.87 V, 2.63 V, and 3.54 V, respectively. Maximum voltage range has been further enhanced by the surface enrichment (oxidized with O2 molecules) of ZnO nanowires. Technique has been opted to mitigate the screening effect during an external stress. After 5 h of oxidation in a sealed chamber at 100 ppm, maximum voltage peaks were pronounced to 2.48 V, 3.19 V, and 4.57 V for K, Na, and Li, respectively. A low-cost, high performance mechanical transducer is proposed for self-powered devices.

Groundwater potential mapping of Tawi River basin of Jammu District, India, using geospatial techniques.

The demand for water is increasing around the world due to population growth, urbanization, industrialization, etc., which is making groundwater a vital natural resource for meeting the growing demand for water. According to the central groundwater report, Jammu district has adequate groundwater potential (GWP) and comes under the safe category. However, the GWP has not been fully utilized, thereby leading to a water shortage in the district. Therefore, this study has been designed to examine the GWP zones in the Tawi River basin of Jammu district using geospatial techniques. For this, several GWP conditioning parameters, such as elevation, slope, geology, geomorphology, rainfall, soil, land use/land cover, topographic wetness index (TWI), drainage density, lineament density, roughness, and curvature, were utilized. The analytical hierarchy process (AHP) technique was used to evaluate the weights of the selected criteria after a pair-wise comparison of each criterion with the rest of the criteria. The result showed that the high GWP zone accounts for 21.98% of the area, the moderate zone covers an area of 40.54%, the low GWP area accounts for about 34.91%, and only 2.57% of the area lies under the very low GWP zone. The validation of GWP zones using 25 monitoring wells showed an accuracy of 80% in GWP modeling. The findings of this study may be utilized in meeting the rising demand for water in the region.

Study of Association Between Different Coronary Artery Disease Presentations and Its Effect on Short-Term Mortality, Readmission, and Cost in Patients Undergoing Percutaneous Coronary Interventions.

Introduction Atherosclerotic coronary artery disease (CAD) is the major cause of mortality in the USA. CAD requiring percutaneous coronary intervention (PCI) can have a wide spectrum of presentations. We reviewed the cost of admission and PCI at the tertiary care center stratified for different CAD presentation types. Methods We performed a retrospective study of 7,389 patients undergoing coronary angiogram at our facility from 2015 to 2017. Patients were selected from CathPCI registry. Chart review was done for readmission and death data. Cost data were provided by the finance department. Patients going for coronary artery bypass surgery (CABG) were excluded. We split the patients based on their need for PCI. Cost analysis was based on CAD presentation types (No symptoms, atypical symptoms, stable angina, unstable angina, NSTEMI [non-ST segment elevation myocardial infarction], STEMI [ST-segment elevation myocardial infarction]). Adjusted linear regression was run for the outcomes. Primary outcomes were 30-day readmission and death. The secondary outcome was cost of admission. Results The final sample size was 6,403. The mean age was 65.6 years (SD: 12.5; male: 63.8%). 2444 required PCI (38%; p < 0.001). PCI group had lower mean age (62.5 years; SD: 12.3, p<0.001) with lower BMI (30.6 vs 31.1, p=0.015). PCI group had significantly lower odds for 30-day readmission (OR: 0.63; CI: 0.45-0.89; p=0.009) and 30-day mortality (OR:0.60; CI: 0.41-0.89; p = 0.011). A severe presentation increased the odds of getting PCI. Cost of admission was higher in all groups receiving PCI. Conclusions PCI group had better 30-day readmission and mortality rates. PCI increases the cost of admission in all CAD types.

Relatively Benign yet a Reversible Cause of Dilated Cardiomyopathy.

Arrhythmia-induced cardiomyopathy secondary to frequent ventricular premature contractions is a well-studied phenomenon; however, there is a paucity of data showing a similar association with frequent atrial premature contractions (APCs). Early recognition and successful APC ablation can reverse left ventricular dysfunction in these patients. (Level of Difficulty: Beginner.).

Two Limitations of Subcutaneous Implantable Cardioverter Defibrillator in the Same Patient Warranting Its Explant.

BACKGROUND A subcutaneous implantable cardioverter defibrillator (S-ICD) is preferred over a transvenous implantable cardioverter defibrillator (TV-ICD) in selected cases owing to a lower rate of lead-related complications such as infections and venous thrombosis. However, the S-ICD has its own limitations, including inappropriate shocks due to oversensed events, and the inability to treat ventricular tachycardia (VT) below a heart rate of 170 beats per minutes (bpm). We present a patient case which showed manifestations of both of these limitations, warranting explant of the device. CASE REPORT A 50-year-old man with a history of nonischemic cardiomyopathy and VT had a S-ICD placed at an outside facility. However, he continued to have VT despite on anti-arrhythmic drugs and required recurrent S-ICD shocks. Device interrogation showed that he was intermittently receiving appropriate shocks for slower VT (with a heart rate ranging from 150 bpm to 160 bpm) due to oversensing of T waves. However, treatment was delayed for other VT episodes owing to appropriate sensing and the patient's heart rate being below the lowest detection zone for S-ICD. Due to slower VT cycle length and frequent oversensed events, the S-ICD was ultimately replaced by a TV-ICD system. CONCLUSIONS This case report emphasizes the importance of S-ICD pre-implant vector screening and the need for paying attention to VT cycle length to prevent inappropriate device shocks and/or delayed therapies.

3D reconstruction of coronary artery bifurcations from coronary angiography and optical coherence tomography: feasibility, validation, and reproducibility.

The three-dimensional (3D) representation of the bifurcation anatomy and disease burden is essential for better understanding of the anatomical complexity of bifurcation disease and planning of stenting strategies. We propose a novel methodology for 3D reconstruction of coronary artery bifurcations based on the integration of angiography, which provides the backbone of the bifurcation, with optical coherence tomography (OCT), which provides the vessel shape. Our methodology introduces several technical novelties to tackle the OCT frame misalignment, correct positioning of the OCT frames at the carina, lumen surface reconstruction, and merging of bifurcation lumens. The accuracy and reproducibility of the methodology were tested in n = 5 patient-specific silicone bifurcations compared to contrast-enhanced micro-computed tomography (µCT), which was used as reference. The feasibility and time-efficiency of the method were explored in n = 7 diseased patient bifurcations of varying anatomical complexity. The OCT-based reconstructed bifurcation models were found to have remarkably high agreement compared to the µCT reference models, yielding r2 values between 0.91 and 0.98 for the normalized lumen areas, and mean differences of 0.005 for lumen shape and 0.004 degrees for bifurcation angles. Likewise, the reproducibility of our methodology was remarkably high. Our methodology successfully reconstructed all the patient bifurcations yielding favorable processing times (average lumen reconstruction time < 60 min). Overall, our method is an easily applicable, time-efficient, and user-friendly tool that allows accurate and reproducible 3D reconstruction of coronary bifurcations. Our technique can be used in the clinical setting to provide information about the bifurcation anatomy and plaque burden, thereby enabling planning, education, and decision making on bifurcation stenting.

Negative nasopharyngeal SARS-CoV-2 PCR conversion in Response to different therapeutic interventions

BACKGROUNDDespite lack of convincing evidence of the efficacy of hydroxychloroquine, it has been suggested to be used for the treatment of SARS-CoV-2 to accelerate the negative virus conversion. We aimed to explore the association between negative nasopharyngeal SARS-CoV-2 PCR clearance and different therapeutic interventions. METHODOLOGYThis was a retrospective cohort study of 93 patients who were admitted to medical ward with a PCR confirmed diagnosis of COVID-19 and met the inclusion criteria in a tertiary hospital in Mecca, Saudi Arabia. There were three interventional subgroups (group A (n=45): who received antimalarial drug only classified as (A1), combined with azithromycin (A2) or combined with antiviral drugs (A3)), and one supportive care group (group B) (n=48). The primary and secondary endpoints of the study were achieving negative SARS-CoV-2 nasopharyngeal PCR sample within five days or less from the start of the intervention and 12 days or less from the diagnose, respectively. RESULTSThe mean age of the patients was 43.9 years (SD:15.9). A median time of 3.00 days (IQR:2.00-6.50) needed from the time of starting the intervention/supportive care to the first negative PCR sample. There was no statistically significant difference neither between the percentage of patients in the interventional group and the supportive care group who achieved the primary or the secondary endpoint, nor in the median time needed to achieve the first negative PCR sample (p>0.05). CONCLUSIONPrescribing antimalarial medications was not shown to shorten the disease course nor to accelerate the negative PCR conversion rate.

A Unique Case of Mitral Valve Dehiscence Post-mitral Valve Repair Diagnosed Using 3D Transesophageal Imaging.

This is an interesting cardiovascular imaging case of a 70-year-old male who presented with heart failure symptoms after recent mitral valve repair with Carpentier-Edwards ring. Ring dehiscence was noted on transesophageal echocardiographic imaging which aided in guiding clinical and surgical courses.

A Case Report of Mesenteric Panniculitis.

A 33-year-old male with a past medical history of hypertension, migraine, depression, and alcohol abuse presented with complaints of nausea, vomiting, and abdominal pain. He was found to have an elevated lipase and ethanol level. CT scan of the abdomen was done which showed peripancreatic fat stranding around the pancreatic head consistent with mild acute uncomplicated pancreatitis. CT scan of the abdomen also revealed multiple clustered nodes in the central mesentery with fatty haziness and ground-glass appearance of the mesenteric fat, representing mesenteric panniculitis.

Troponin Levels at Presentation Before Coronary Angiogram and Their Association With Cost, Mortality, and Readmission.

Background and objective In patients undergoing coronary angiogram, the degree of cardiac enzyme elevation at presentation has been thought of as a strong and independent predictor of in-hospital mortality and readmission. Recent studies, however, have suggested a lack of clarity regarding this speculation, particularly with regard to troponin elevations. Additionally, the impact of troponin levels (TnI) at presentations on cost is poorly understood. In this study, we aimed to evaluate the association of Tnl at initial presentation with 30-day all-cause readmission and all-cause mortality as well as admission costs. Methods This study was a retrospective analysis of 7,388 patients who underwent coronary angiogram at our facility from 2015 to 2017. Patients were identified from a local CathPCI Registry® registry, and a subsequent chart review was performed for readmission and mortality data. Cost data were provided by our in-facility finance department. We excluded patients with incomplete records and those who required coronary artery bypass grafting (CABG). After the exclusion of patients deemed ineligible, the final sample size eligible for analysis was 1,163. Patients were divided into two groups based on Tnl at presentation with a cut-off value of 0.04 ng/ml. Adjusted regression and multivariate analysis were used for clinical outcomes. Primary outcomes were 30-day readmission and mortality. The secondary outcome was the admission cost. Results Within our cohort, the average participant age was 64.6 years (SD: 12.7), and the majority of them were male (70.7%). Of these patients, 207 had lower TnI (<0.04 ng/ml), while 956 had higher TnI at presentation. The high TnI (≥0.04 ng/ml) group had a significantly higher number of patients with a family history of coronary artery disease (CAD) (13.8% vs. 7.7%: p=0.017) and those on dialysis (3.2% vs. 0.5%: p=0.028) compared to the low Tnl group. Additionally, we did not find any significant difference in 30-day mortality or readmission between the two groups in our cohort. On average, each patient in the high TnI group spent $936 more for hospital admissions compared to patients in the low Tnl group. However, this difference was not statistically significant. Conclusions Tnl at admission did not reveal a significant impact on 30-day mortality or readmission, which is consistent with the findings of previous studies. A high Tnl at admission increased the cost of admission; however, the difference was not statistically significant in our cohort.

Relation of Frailty to Cost for Patients Undergoing Transcatheter Aortic Valve Implantation.

Frailty is associated with significant morbidity and mortality for patients undergoing transcatheter aortic valve implantation (TAVI). In addition to clinical outcomes, cost is an important factor to inform clinical decision-making around TAVI. However, the association of frailty with cost is unknown. This study tested whether frailty was associated with cost for adult patients who underwent TAVI at a moderate-volume single center between December 2012 and April 2018 (n = 431). Frailty was determined from pre-TAVI clinical visits as a composite of 2 markers: 5-meter walk time (abnormal: >6 seconds or unable to perform) and serum albumin (abnormal: <3.5 g/dl). Patients were excluded if missing frailty assessment or covariate data (24). Cost data were derived from financial statements, and assigned at the department-level by charge code. Multivariable regression models were adjusted for age, gender, and procedural co-morbidities. Of 407 patients in the analytical sample (mean age 81 years, 49% female), 74 (18%) were determined to be frail. Adjusted mean total costs were $6,397 higher for frail patients ($78,823 vs $72,425, p = 0.042) compared with nonfrail. Higher total costs were driven by department-level charges associated with longer in-hospital length of stay (7.6 vs 3.3 days, p <0.001): room, physical therapy, pharmacy, laboratory, supply, and imaging services. Providers must address frailty proactively to salvage the benefit associated with TAVI.

Absence of the TRIP13 c.1060C>T Mutation in Wilms Tumor Patients From Pakistan.

BACKGROUND AND AIM: Wilms tumor (WT) is the most common childhood malignant renal tumor. Germline mutations in several WT predisposition genes have been identified. However, the fundamental cause of most WT patients remains unexplained. Recently, a founder mutation, c.1060C>T (p. Arg254X) in a mitotic spindle checkpoint gene, TRIP13, was reported in 5 unrelated children with WT from the United Kingdom, of Pakistani descent from Azad Kashmir region. This observation suggests other children with WT in Pakistan may also harbor this mutation. We conducted the first study to assess the contribution of TRIP13 c.1060C>T mutation to WT in Pakistan. MATERIALS AND METHODS: Constitutional genomic DNA from 68 Pakistani individuals including unrelated WT cases (n=26) and one (n=10) or both (n=32) of their parent(s) were screened for the TRIP13 c.1060C>T mutation using DNA sequence analysis. We also included positive controls in the analyses. RESULTS: The median age of WT diagnosis was 3.0 years (range, 0.75 to 10). The TRIP13 c.1060C>T mutation was not found in any WT patient (n=26) or their parents (n=42). Twenty-four patients (92.4%) presented with unilateral tumor and 2 patients (7.7%) were diagnosed with synchronous bilateral WT. Thirteen patients (50%) reported parental consanguinity. Thirteen patients (50.0%) belonged to the Punjabi ethnicity and 1 patient (3.8%) had a Kashmiri background. Four patients (16.7%) reported a family history of WT or other malignancies. The predominant histologic subtype was stromal (46.2%). The majority of patients presented with >5 cm of tumor size (81%). None of the patients had a personal or family history of congenital anomalies, or associated genetic syndromes. CONCLUSIONS: Our findings suggest that TRIP13 c.1060C>T mutation may be infrequent in Pakistani WT cases. Further evaluation of this mutation in a large number of WT patients of Kashmiri heritage and various ethnic backgrounds from Pakistan is warranted.
