Generalized Trace Inequalities for Q Uncertainty Relations
Published on: 20th August, 2024
Iin 2015 we obtained non-hermitian extensions of Heisenberg type and Schrödinger type uncertainty relations for generalized metric adjusted skew information or generalized metric adjusted correlation measure and gave the results of Dou-Du in 2013 and 2014 as corollaries. In this paper, we define generalized quasi-metric adjusted Q skew information for different two generalized states and obtain corresponding uncertainty relation. The result is applied to the inequalities related to fidelity and trace distance for different two generalized states which were given by Audenaert, et al. in 2009 and 2008; and Powers-Strmer in 1970. 2010 Mathematics Subject Classification: 15A45, 47A63, 94A17.
Defibrillation of Atrial Fibrillation is not Associated with Increased Risk of Ventricular Fibrillation – The VCD-Trial (Clinical Trial of Electrical Therapy for Atrial Fibrillation using R-wave Guided Cardioversion Versus Defibrillation)
Published on: 19th August, 2024
Background: Because of a possible risk of induction of Ventricular Fibrillation (VF) by defibrillation of atrial fibrillation (AF) postulated by LOWN and coworkers, synchronized cardioversion is used worldwide. This prospective, randomized study assessed the efficacy and safety between R-wave controlled cardioversion and defibrillation of AF at 2 study centers in Cologne, Germany. Hypothesis: Defibrillation is not significantly different from cardioversion primarily in the occurrence of VF or sustained Ventricular Tachycardia (VT) and secondarily in restoring sinus rhythm, inducing non-sustained VT, asystole, or bradycardia.Methods: 146 patients at an outpatient practice and 122 at the university hospital were randomized to cardioversion (n = 140) or defibrillation (n = 124).Results: Cardioversion was successful in 92.1% of cases and defibrillation in 87.1%. The difference in efficacy was not statistically significant. In n = 1 patients receiving defibrillation, VF occurred after the first shock (200J) and immediate defibrillation (200J) restored sinus rhythm. In the n = 1 case, asystole occurred during cardioversion which terminated spontaneously. In n = 1 patients cardioverted and n = 2 who were defibrillated, sinus bradycardia occurred requiring Atropine in two cases. There were no thromboembolic events within 10 days. N = 9 patients reverted to AF within two hours. No patients died. Conclusion: Electrical conversion of AF can be performed with similar results and low risk with both R-wave-triggered cardioversion and defibrillation. In particular, defibrillation with higher energies (> 100J) can be performed as effectively and safely without a statistically significant increased risk of VF or VT. There was no difference in efficacy and risk between electrotherapy performed in the outpatient and inpatient settings.

Investigation of Stain Patterns from Diverse Blood Samples on Various Surfaces
Published on: 12th August, 2024
Bloodstain Pattern Analysis (BPA) is a crucial forensic technique in crime scene investigation, employing the interpretation of blood spatter patterns to reconstruct event sequences and determine spatial relationships between victims and surfaces. This study explores BPA’s application in forensic science, emphasizing its role in establishing links between crimes and culprits, as posited by Edmond Locard’s exchange principle. The research examines how bloodstain shape, size, and distribution reveal critical information about impact angles, areas of convergence, and points of origin, while also providing insights into blood flow direction, force applied, suspect positioning, and weapons used. The investigation delves into various bloodstain types, including void patterns, spikes, and satellite stains, and their formation on different surfaces. To enhance understanding of blood behaviour from various sources, the study compares blood samples from three species: human (Homo sapiens), obtained from a professional doctor from discarded piles with precaution from a government hospital in Laxmangarh, Rajasthan and goat (Capra aegagrus hircus), and chicken (Gallus gallus domesticus), obtained from butcher shops in Laxmangarh, Rajasthan. The experimental setup involves dropping blood from a height of 50 centimetre’s and measuring the resulting stain dimensions. This comprehensive approach to BPA research aims to refine crime scene analysis techniques, ultimately contributing to more accurate event reconstructions and enhanced forensic investigations. The study underscores the importance of BPA in modern forensic science while acknowledging the need for its integration with other investigative methods to ensure robust and reliable crime scene interpretations.
Single Coronary Artery Associated with an Arteriovenous Communication: An Incremental Diagnostic Value of Coronary CTA
Published on: 12th August, 2024
Single coronary artery and coronary arteriovenous communication are rare congenital cardiac anomalies with potentially harmful effects, making the diagnosis essential for the appropriate management. The coexistence of these two anomalies is exceptional. We present a case illustrating the diagnostic power of Coronary CTA in depicting this unusual combination.
Required Elements for Next-generation Prognostic Index beyond Left Ventricular Ejection Fraction in Heart Failure
Published on: 12th August, 2024
Many reports are showing no differences in prognosis between patients with Heart Failure (HF) with preserved and reduced ejection fraction. All-in-one analysis with a multivariable model, including clinical characteristics, blood test, comorbidity, and echocardiographic indices, on clinical outcomes in patients with HF has not been performed rarely in previous studies. We have to accept the need to be more comprehensive in the outcome analysis of patients with HF and consider the intricate interplay of multiple variables in patient outcomes.
Antibacterial Resistance and Extended-Spectrum Beta-Lactamase (ESBL) Phenotypes in Enterobacteriaceae Isolated from Fecal Samples of Humans and Animals in Selected Local Government Areas of Nasarawa State, Nigeria
Published on: 13th August, 2024
It is quite alarming the increasing rate of antibacterial resistance all over the world considering the public health threat and the re-emergence of multi-drug resistant Enterobacteriaceae. The aim of this study is Antibacterial resistance and phenotypic detection of Extended Spectrum Beta-Lactamase (ESBL) producing Enterobacteriaceae isolated from human and animal fecal samples in selected local government areas of Nasarawa state, Nigeria was carried out in the study. Hundred (100) samples comprising human and animal (goats, cattle, and chicken) were collected and 55 samples were multidrug resistant. A commercial biochemical kit (Eneterosystem 18R) was used for the isolation and identification of Enterobacteriaceae. Kirby Bauer Disk Diffusion Method was used for antibacterial susceptibility testing of Enterobacteriaceae isolates. The Double Disc Synergy Test (DDST) method was also used for the phenotypic confirmation test of Extended Spectrum Beta Lactamase (ESBL). The occurrence of multidrug-resistant isolates shows that Escherichia coli (100.00%) which is the highest, Proteus mirabilis (14.54%), Klebsiella pneumoniae, and Salmonella enterica (10.90%), while the occurrence of Shigella flexneri (9.09%) was the lowest. The Enterobacteriaceae isolates were more resistant to Cefuroxime, Cefexime, Amoxicillin Clavulanate, and Imipenem/Cilastatin with percentage resistance ranges from 66.6% - 100%. The occurrence of ESBL producers shows that Escherichia coli (60.00%) and Proteus mirabilis (62.5%) were high while Shigella flexneri (20.0%) had a low occurrence of ESBL. The sale and in-discriminate use of antibiotics without a prescription is an important regulatory issue in the abuse of antibiotics for both humans and animals. The Beta-Lactam and gentamycin antibiotics were not effective against the Multi-Drug Resistant (MDR) isolates and most of the isolates were ESBL producers.
Imaging Challenge in Recurrent Spontaneous Coronary Artery Dissection (SCAD): A Case Report
Published on: 8th August, 2024
Spontaneous Coronary Artery Dissection (SCAD) represents a significant cause of acute coronary syndrome (ACS) in patient populations with low-risk cardiovascular profiles and, therefore can be sometimes underdiagnosed. On the other hand, it often preserves the typical clinical presentation of ACS which makes coronary artery angiography (CAG) execution mandatory. A 62-year-old woman with a history of recurrent SCAD presented to the emergency department for a new episode of acute chest pain with troponin elevation. CAG revealed an ambiguous angiography image suggesting a sub-occlusive type 2 SCAD involving the distal segment of the left circumflex artery. The patient was managed conservatively due to the absence of ongoing ischemia or hemodynamic instability. At the seven-day follow-up, a computed tomography coronary angiography (CTCA) was performed to better assess SCAD and detect concomitant associated arteriopathies. Optimized medical therapy was prescribed at the discharge and at one-month follow-up, no recurrence of symptoms was referred.
Elderly (> 70 years) Multiple Myeloma Patients Benefit Equally from Autologous Hematopoietic Stem Cell Transplantation When Compared to Younger Patients
Published on: 8th August, 2024
Autologous Hematopoietic Stem Cell Transplantation (AHSCT) performed after induction therapy is the standard of care for newly diagnosed Multiple Myeloma (MM) patients who qualify. Our institution has performed AHSCT for MM since 1991, and in this study, we sought to retrospectively examine the outcomes of 303 MM patients who underwent AHSCT from 1991-2021. We focused on Overall Survival (OS) and Progression-Free Survival (PFS) in patients in addition to Landmark survival (1-year post-transplantation). We found that in elderly patients > 70 years of age there was no significant difference in OS at 12 years, with 51% for patients < 70 years of age and 50% > 70; these were the same numbers for PFS at 12 years as well. We also found that median overall survival is improving overall with each decade in our transplanted MM patients with patient survival improved to over > 80% regardless of age at 7 years, when the previous median overall survival was 6 - 6.6 years before 2001. Given our findings, supported by others, we show that survival is continually improving over time in MM AHSCT patients and that AHSCT can be performed safely with equivalent landmark and long-term PFS and OS in patients of advanced age.
Obstetric Renal Failure: Causes, Prognosis, and Evolution
Published on: 8th August, 2024
The incidence of obstetric acute renal failure remains significant in developing countries. The aim of our study is to define the risk factors involved in the occurrence of ARF during pregnancy or during the immediate postpartum period and to evaluate its evolutionary profile in terms of epidemiology, etiopathogenesis, and therapeutic management over the years in Morocco. This is a retrospective study conducted in the maternal-infant resuscitation service of the Ibn Rochd University Hospital of Casablanca, over the period from January 2020 to August 2023, including 95 patients. The current incidence in our series over this period was 22.2%. The mean age of our population was 33 ± 7.74 years [18-43 years], 67.3% of patients were in the gestational period, compared to 33.7% in the immediate postpartum period. Fourteen patients were primiparous (8.6%), 27.4% had a history of miscarriage, and 10.7% had a history of pre-eclampsia. Oligo-anuria was initially identified in 24 patients. The most frequent etiology was pre-eclampsia (56.7%), followed by hemorrhage (27%) and sepsis (19.3%). The evolution was marked by recourse to hemodialysis in 62% of cases, with a maternal mortality of 26%. The existence of heart disease, the context of pre-eclampsia, and the use of diuretics and vasoactive drugs were significantly correlated with maternal survival. No factor was correlated with secondary recovery from ARF. The development of health structures and the optimization of screening strategies are the keywords for prevention.
