Complete surgical revascularization after NSTEMI and unstable angina in patients with multivessel coronary artery disease: Institutional experience.

INTRODUCTION: The feasibility and standardization of coronary artery bypass grafting (CABG) in patients with non-ST-elevation acute coronary syndrome (NSTE-ACS) and unstable angina (UA) remain topics of ongoing debate. In this study, feasibility and early-term outcomes of CABG in patients with NSTE-ACS and UA were discussed. METHODS: This study enrolled 79 patients who underwent on-pump CABG with complete revascularization between January 2020 and May 2022. the survival rates analyzed using Kaplan Meier test with log rank test. The p value of statistical significance was taken as below 0.05. RESULTS: Preoperatively, the patients had a mean age of 60.9 years and a BMI of 28.0. The medical history included hypertension (50.6%), peripheral arterial disease and atrial fibrillation (12.7%), and other comorbidities such as COPD (22.8%) and type 2 diabetes mellitus (44.3%). Intraoperatively, the mean distal anastomosis count was 3.4, with average cardiopulmonary bypass and aortic cross-clamp times of 84.0 and 49.0 min, respectively. Early-term outcomes revealed low rates of mortality (2.5%) and complications such as myocardial infarction (1.3%), acute kidney injury (5.1%) and transient ischemic attack (5.1%). Post-discharge outcomes demonstrated low cardiac and all-cause mortality rates (2.5% and 3.8%, respectively) and a high overall survival rate (93.7%) at 12-month follow-up. CONCLUSION: This study demonstrated the feasibility and positive outcomes of complete surgical revascularization in patients with UA and NSTE-ACS. It showed no graft occlusion or stroke, low complication rates and promising survival outcomes. Further research is needed for confirmation and to establish the procedure's efficacy and safety in this patient population.

Complete surgical myocardial revascularization in patients with declined renal functions: 12-month outcomes.

INTRODUCTION: This retrospective observational study aimed to evaluate the feasibility and effectiveness of complete revascularization coronary artery bypass grafting (CABG) in patients with multi-vessel disease (MVD)-CAD and declined renal functions, addressing the knowledge gap regarding optimal treatment strategies and outcomes in this specific patient population. METHODS: Between 2020 and 2022, a total of 58 patients underwent on-pump coronary artery bypass grafting surgery for complete myocardial revascularization in this study. To assess overall survival, Kaplan-Meier with the log-rank test was conducted for statistical analysis. RESULTS: The mean age of cohort was 60.7. The findings showed a high prevalence of medical conditions such as hypertension (50.0%), diabetes (50.0%), and anaemia (41.4%) among the participants. Intraoperatively, low cardiac output syndrome was reported in 5.2% of cases, while perioperative outcomes indicated a need for transfusions in 53.5% of cases and an in-hospital mortality rate of 3.4%. At the 12-month follow-up, no redo revascularization or renal replacement therapy was required, but cardiac mortality was 5.2% and all-cause mortality was 6.9%. CONCLUSIONS: The study concluded that complete revascularization is safe for these patients and highlights the potential benefits, emphasizing the need for further research in optimizing revascularization techniques for this population.

Chemical Analysis, Antioxidant, and Antibacterial Potential of Aqueous Extract of Broccoli (Brassica oleracea) Using GC-ms.

Antioxidant and antibacterial chemicals are key sources in medicinal plants. Alkaloids, phenolics, steroids, terpenes, flavonoids, terpenes, and volatile oils are a few of these plants' secondary metabolites. Phytochemicals, particularly the secondary metabolites produced by plants, are important for human nutrition, well-being, illness prevention, and antibacterial properties. This study aimed to ascertain the aqueous broccoli extract's chemical makeup. The phytochemical molecule that the GC-MS technique identified. The DPPH assay, which is appropriate for regular plant material screening, was performed to assess the antioxidant capacities of broccoli extract (in vitro). Subsequently looks at how well they perform against different Gram-positive and Gram-negative harmful microorganisms. GC-MS analysis of Broccoli extract revealed the existence of the9-Octadecenamide, [C18H35O], Hexadecane [c16h34] and 2, 2, 2-trifluoroethyl 2-methyltetrahydro-5-oxo-3- furancarboxylate [C23H33NO6]. There were significant changes in the extract's ascorbic acid-free radical scavenging activity at 200, 100, and 25 g/ml (P≤0.05), and the activity was dose-dependent. The effectiveness of aqueous broccoli extract as a powerful, broad-spectrum antibacterial agent against tested bacteria is demonstrated by an increase in the diameter of the inhibition zone, which increases in direct proportion to the concentration of the extract and even surpasses the activity of some antibiotics. An appropriate concentration of aqueous broccoli extract strongly inhibits microbial and antioxidant growth, especially when treating external infections without any danger against resistant bacterial isolates; it is strongly advised to use aqueous broccoli extract as a cost-effective alternative antibacterial and antioxidant agent.

A rare ventriculoarterial connection: double outlet of both ventricles.

Ventriculoarterial connection is one of the important points of the segmental approach to congenital cardiac malformations. Double outlet of both ventricles is a rare form where both great arterial roots override the interventricular septum. In this article, we aimed to draw attention to this very rare form of ventriculoarterial connection by presenting an infant case diagnosed using echocardiography, CT angiography, and 3-dimensional modelling.

Spatial Distribution and Long-Term Persistence of Wolbachia-Infected Aedes aegypti in the Mentari Court, Malaysia.

Dengue is endemic in Malaysia, and vector control strategies are vital to reduce dengue transmission. The Wolbachia strain wAlbB carried by both sexes of Ae. aegypti was released in Mentari Court, a high-rise residential site, in October 2017 and stopped after 20 weeks. Wolbachia frequencies are still being monitored at multiple traps across this site, providing an opportunity to examine the spatiotemporal distribution of Wolbachia and mosquito density with respect to year, residential block, and floor, using spatial interpolation in ArcGIS, GLMs, and contingency analyses. In just 12 weeks, Wolbachia-infected mosquitoes were established right across the Mentari Court site with an overall infection frequency of >90%. To date, the Wolbachia frequency of Ae. aegypti has remained high in all areas across the site despite releases finishing four years ago. Nevertheless, the Wolbachia invaded more rapidly in some residential blocks than others, and also showed a relatively higher frequency on the eighth floor. The Ae. aegypti index tended to differ somewhat between residential blocks, whilst the Ae. albopictus index was relatively higher at the top and bottom floors of buildings. In Mentari Court, only a short release period was required to infiltrate Wolbachia completely and stably into the natural population. The results inform future releases in comparable sites in a dengue control programme.

Estimation of Serum Ferritin in Mucormycosis Patients and Prognostication Based on the Ferritin Value.

INTRODUCTION: Coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been implicated in a variety of vulnerable bacterial and fungal diseases. Mucormycosis is a life-threatening infection caused by fungi belonging to the class Zygomycetes and the order Mucorales. The aim of the present study is to evaluate the level of serum ferritin level in mucormycosis patients and to prognosticate them based on those values. MATERIALS AND METHODS: This prospective observational study was conducted in the Department of General Medicine, Mahatma Gandhi Memorial Government Hospital, Tiruchirappalli, in 50 diagnosed mucormycosis patients. RESULTS: During the study period, 44 had prior COVID-19 illness (post-COVID). Six patients had mucormycosis with no prior COVID-19 illness. Rhino-orbital involvement was found in 44 of the 50 cases, with three of them having cerebral extension. Forty-one cases recovered and were discharged, six cases remained sick and were hospitalized, and three died. The post-COVID patients (554.13 ± 371.60) have greater serum ferritin levels than non-COVID patients (259.95 ± 110.15), which are statistically significant.  Conclusion: Mucormycosis patients tend to have higher serum ferritin values, especially among non-survivors and sick patients than survivors. For a better chance of recovery and survival, early identification, surgical debridement, and antifungal medications are essential.

CRISPR prime editing with ribonucleoprotein complexes in zebrafish and primary human cells.

Prime editors have been delivered using DNA or RNA vectors. Here we demonstrate prime editing with purified ribonucleoprotein complexes. We introduced somatic mutations in zebrafish embryos with frequencies as high as 30% and demonstrate germline transmission. We also observed unintended insertions, deletions and prime editing guide RNA (pegRNA) scaffold incorporations. In HEK293T and primary human T cells, prime editing with purified ribonucleoprotein complexes introduced desired edits with frequencies of up to 21 and 7.5%, respectively.

Comparison of the impact of open and laparoscopic inguinal hernia operations on male sexual function and pain during sexual activity.

In the current study, we aimed to compare sexual function and pain during the sexual activity of men who underwent surgery with the open or laparoscopic total extraperitoneal hernia repair techniques. Patients were randomised into two groups according to the technique used during the operation: the Lichtenstein hernia repair open technique (n = 63) and the laparoscopic total extraperitoneal repair technique (n = 57). In both groups, postoperative sexual function score was significantly improved compared with the preoperative period (p < .001 for both), but the change was higher in the laparoscopy group (6.8 ± 3.7) compared with the open group (4.3 ± 4.4) (p < .001). In both groups, postoperative pain during sexual activity score was significantly decreased compared with the preoperative period (p = .001 for the open group and p < .001 for the laparoscopy group), with the amount of decrease being higher in the laparoscopy group (1.8 ± 0.9) compared with the other (1.1 ± 1.4) (p = .002). This study showed that both hernia repair techniques had a positive impact on sexual function and pain during sexual activity. The improvement in sexual parameters and pain during sexual intercourse was better in the laparoscopy group.

Leukemic stem cells shall be searched in the bone marrow before "tyrosine kinase inhibitor-discontinuation" in chronic myeloid leukemia.

BACKGROUND: Leukemic stem cells (LSCs) of chronic myeloid leukemia (CML), persisting in the bone marrow (BM) niche, could be responsible for the relapses within the patients of whom the treatment-free remission (TFR) had been attempted. We assessed the presence of the CML LSCs in the peripheral blood (PB) and concurrently in the BM in the patients with chronic-phase CML (CP CML). PATIENTS AND METHODS: Thirty-eight patients with CP CML were included into the study. CD45+ /CD34+ /CD38- cells with positive CD26 expression were considered as CML LSCs (CD26+ LSC) by using multiparameter flow cytometry (FCM). RESULTS: Mean BCR-ABL, PB LSC, and BM LSC were 58.528 IS (37.405-83.414 IS), 237.5 LSC/µL (16-737.5 LSC/µL), and 805 LSC/106  WBCs (134.6-2470 LSC/106  WBCs), respectively, in newly diagnosed CML patients. In the patients with BCR-ABL positive hematopoiesis, mean BCR-ABL, PB LSCs, and BM LSCs were 30.09 IS (0.024-147.690 IS), 13.5 LSC/µL (0-248.7 LSC/µL) and 143.5 LSC/106  WBCs (9-455.2 LSC/106  WBCs), respectively. No CML LSCs were detected in PB of patients who achieved deep molecular response (DMR). BM LSCs of the patients who were in DMR were 281.1 LSC/106  WBCs (3.1-613.7 LSC/106  WBCs). The amount of PB LSCs was highest in patients with newly diagnosed CML (P < .001). CONCLUSION: LSCs persisted in the BM of the patients with DMR, whereas there was no LSCs in the peripheral blood. The investigation of the CML LSCs in bone marrow before deciding TKI discontinuation could be justified to achieve and maintain stable TFR.

Protein Kinases in Hematological Disorders.

Cell signaling is an important part of the complex system of molecular communication that governs basic cellular activities and coordinates cell cycle machinery. Pathological alterations in the cellular information processing may be responsible for the diseases such as cancer. Numerous diseases may be treated effectively via the pharmacological management of cellular signaling. Protein kinases (PK) have significantly important roles in the cell signal transduction process. Protein kinases phosphorylate serine, threonine, tyrosine and histidine amino acids in a wide variety of molecular networks. Two main PK groups are distinguished; serine/threonine kinase and tyrosine kinases. MAPK (mitogen-activated protein kinases), ERK, EGFR (epidermal growth factor receptor), src, abl, FAK (focal adesion kinase), and JAK (janus family kinase) are considered as the main PK molecular networks. Protein kinases are closely related to the pathobiology of hematologic neoplastic disorders. For instance; JAKV617F point mutation-causing polycythemia vera and essential thrombocytosis occur at the position 617 in the JH2 domain of the JAK2 gene. The protein kinase inhibitor drugs targeting specific kinase molecules have already been developed and widely used in the field of Clinical Hematology. The existence of a local renin-angiotensin system (RAS) specific to the hematopoietic bone marrow (BM) microenvironment had been proposed two decades ago. Local BM RAS is important in hematopoietic stem cell biology and microenvironment. There are interactions among the local BM RAS and PK. For example, ACE2-ang(1-7)-Mas axis inhibits p38 MAPK/NF-КB signaling pathway. The Local BM RAS may have a role in the effect on PK in this biological spectrum. The aim of this review is to outline the functions of PKs in the pathobiology of hematologic neoplastic disorders.

Cardiac resynchronization therapy in paediatric patients with congenital heart disease: single centre with 10 years of experience.

OBJECTIVES: In recent years, cardiac resynchronization therapy (CRT) has also started to be performed in the paediatric and CHD population. This study aimed to evaluate the efficacy of CRT in children with CHD. PATIENTS AND METHODS: Patients with CHD who underwent CRT treatment in our paediatric cardiology clinic between January, 2010 and January, 2020 were included in the study. Demographic findings, 12-lead electrocardiograms, echocardiograms, clinical characteristics, management strategies, and outcomes were reviewed systematically. RESULTS: The study population consisted of 18 CHD patients who had been treated with CRT for 10 years in our institution. The median age was 11 years (2.2-18 years) and the median weight was 39 kg (10-81 kg). Systemic ventricle was left ventricle in 13 patients, right ventricle in 4 patients, and 1 patient had single-ventricle physiology. CRT implantation indications were as follows: dysfunction after permanent pacemaker in 11 patients, dysfunction after left bundle branch block in 4 patients, and systemic ventricular dysfunction in 3 patients. CRT implantation techniques were epicardial (n = 13), hybrid (n = 4), and transvenous (n = 1) methods. QRS duration significantly decreased after CRT implantation (160 versus 124 m/second, p < 0.05). Median systemic ventricle ejection fraction (EF) significantly increased after the procedure (30 versus 50%, p < 0.05). Fourteen patients (78%) were responders, two patients (11%) were superresponders, and two patients (11%) were non-responders after the CRT treatment. One patient deceased during follow-up. Median follow-up duration was 40 months (6-117 months). CONCLUSION: When electromechanical dyssynchrony occurs in paediatric cases with CHD and developing heart failure, patients should be evaluated in terms of CRT to improve ventricular function. Alternative CRT therapy will be beneficial in these cases that do not improve clinically despite optimal medical treatment.

Platelet Activation in Ocular Behçet's Patients with Posterior Segment Involvement.

PURPOSE: The aim of the present study was to assess platelet activation by analyzing three platelet activation parameters in ocular Behçet's disease (BD): mean platelet volume (MPV), platelet distribution width (PDW), and plateletcrit (PCT). METHODS: Twenty-nine patients with active ocular BD (Group 1), 40 patients with inactive ocular BD (Group 2), and 40 healthy adult individuals serving as controls (Group 3) were evaluated. All of the individuals had been performed the complete ophthalmologic evaluation. The levels of MPV, PDW, and PCT were measured in each group. RESULTS: The mean MPV level was 8.40 ± 0.97 in Group 1, 8.32 ± 1.04 in Group 2, and 7.77 ± 0.72 in Group 3. The mean PDW level was 15.12 ± 1.09 in Group 1, 14.97 ± 1.02 in Group 2, and 14.52 ± 0.82 in Group 3. The mean PCT level was 0.23 ± 0.07 in Group 1, 0.21 ± 0.04 in Group 2, and 0.18 ± 0.03 in Group 3. MPV, PDW, and PCT levels were significantly higher in ocular BD patients than controls (P < 0.05). CONCLUSION: Platelet activation may affect vascular occlusion in ocular Behçet's patients with posterior segment involvement. This result may be important in evaluating ocular BD patients.

CRISPR C-to-G base editors for inducing targeted DNA transversions in human cells.

CRISPR-guided DNA cytosine and adenine base editors are widely used for many applications1-4 but primarily create DNA base transitions (that is, pyrimidine-to-pyrimidine or purine-to-purine). Here we describe the engineering of two base editor architectures that can efficiently induce targeted C-to-G base transversions, with reduced levels of unwanted C-to-W (W = A or T) and indel mutations. One of these C-to-G base editors (CGBE1), consists of an RNA-guided Cas9 nickase, an Escherichia coli-derived uracil DNA N-glycosylase (eUNG) and a rat APOBEC1 cytidine deaminase variant (R33A) previously shown to have reduced off-target RNA and DNA editing activities5,6. We show that CGBE1 can efficiently induce C-to-G edits, particularly in AT-rich sequence contexts in human cells. We also removed the eUNG domain to yield miniCGBE1, which reduced indel frequencies but only modestly decreased editing efficiency. CGBE1 and miniCGBE1 enable C-to-G edits and will serve as a basis for optimizing C-to-G base editors for research and therapeutic applications.

Ankaferd hemostat (ABS) as a potential mucosal topical agent for the management of COVID-19 syndrome based on its PAR-1 inhibitory effect and oestrogen content.

COVID-19 due to the SARS-CoV-2 infection is a multi-systemic immune syndrome affecting mainly the lungs, oropharyngeal region, and other vascular endothelial beds. There are tremendous ongoing efforts for the aim of developing drugs against the COVID-19 syndrome-associated inflammation. However, currently no specific medicine is present for the absolute pharmacological cure of COVID-19 mucositis. The re-purposing/re-positioning of already existing drugs is a very important strategy for the management of ongoing pandemy since the development of a new drug needs decades. Apart from altering angiotensin signaling pathways, novel drug candidates for re-purposing comprise medications shall target COVID-19 pathobiology, including pharmaceutical formulations that antagonize proteinase-activated receptors (PARs), mainly PAR-1. Activation of the PAR-1, mediators and hormones impact on the hemostasis, endothelial activation, alveolar epithelial cells and mucosal inflammatory responses which are the essentials of the COVID-19 pathophysiology. In this context, Ankaferd hemostat (Ankaferd Blood Stopper, ABS) which is an already approved hemostatic agent affecting via vital erythroid aggregation and fibrinogen gamma could be a potential topical remedy for the mucosal management of COVID-19. ABS is a clinically safe and effective topical hemostatic agent of plant origin capable of exerting pleiotropic effects on the endothelial cells, angiogenesis, cell proliferation and vascular dynamics. ABS had been approved as a topically applied hemostatic agent for the management of post-surgical/dental bleedings and healing of infected inflammatory mucosal wounds. The anti-inflammatory and proteinase-activated receptor axis properties of ABS with a considerable amount of oestrogenic hormone presence highlight this unique topical hemostatic drug regarding the clinical re-positioning for COVID-19-associated mucositis. Topical ABS as a biological response modifier may lessen SARS-CoV-2 associated microthrombosis, endothelial dysfunction, oropharyngeal inflammation and mucosal lung damage. Moreover, PAR-1 inhibition ability of ABS might be helpful for reducing the initial virus propagation and mocasal spread of COVID-19.

In vitro analysis of the renin-angiotensin system and inflammatory gene transcripts in human bronchial epithelial cells after infection with severe acute respiratory syndrome coronavirus.

INTRODUCTION: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a recently identified coronavirus family member that triggers a respiratory disease similar to severe acute respiratory syndrome coronavirus (SARS-CoV). SARS-CoV and SARS-CoV-2 are very similar to each other in many respects, such as structure, genetics, and pathobiology. We hypothesized that coronaviruses could affect pulmonary tissues via integration with the critical immune genes after their interaction with renin-angiotensin system (RAS) elements. The aim of the present bioinformatics study was to assess expression changes of the RAS and non-RAS genes, particularly immune response genes, in the lung epithelial cells after infection with SARS-CoV. METHODS: Linear regression, hierarchical clustering, pathway analysis, and network analysis were performed using the E-GEOD-17400 data set. RESULTS: The whole-genome expression data of the lung epithelial cells infected with SARS-CoV for 12, 24, and 48 hours were analyzed, and a total of 15 RAS family and 29 immune genes were found to be highly correlated with the exposure time to the virus in the studied groups. CONCLUSION: RAS genes are important at the initiation of the infections caused by coronavirus family members and may have a strong relationship with the exchange of immune genes in due course following the infection.

Comparison of bortezomibcyclophosphamide- dexamethasone versus bortezomib-dexamethasone based regimens in newly diagnosed multiple myeloma patients.

The treatment landscape and clinical outcome of multiple myeloma (MM) patients have changed in the last decades, with an improved median survival of 8-10 years. This study aimed to evaluate the bortezomib, cyclophosphamide and dexamethasone (VCD) regimen versus bortezomib and dexamethasone (VD) regimen in patients with newly diagnosed MM. This study has been performed in a retrospective manner. One hundred and three patients with newly diagnosed MM who received chemotherapy at our tertiary care center between the years of 2009 and 2018 were evaluated. A total of 103 patients were included. The 5-year overall survival (OS) for patients who received VD regimen and patients who received VCD regimen were 75% and 83%, respectively. The OS for VD patients was 113.1±12.5 versus 122.2±9.5 months for VCD patients with no statistically significant difference (P=0.47). The 5- year PFS (progression free survival) for patients who received VD regimen and patients who received VCD regimen were 66% and 75%, respectively. The PFS for VCD patients was higher than the PFS for VD patients (67.1±7.4 versus 97.7±13.4 months), but no statistically significant difference was observed (P=0.59). Relapse rate (P=0.002) and mortality rate (P=0.01) were higher in VD group than VCD group and they were statistically significant. The OS and PFS were clinically longer in patients receiving VCD regimen than in patients receiving VD regimen, although not statistically significant. Cyclophosphamide should be given to patients at physician discretion and depending on patient's frailty function.

Pharmacobiological management of hemostasis within clinical backgrounds via Ankaferd hemostat (Ankaferd blood stopper).

Ankaferd hemostat (Ankaferd blood stopper [ABS], Istanbul, Turkey) is a hemostatic agent affecting red blood cell-fibrinogen interactions. ABS has been traditionally used in Anatolia as a hemostatic agent for centuries. ABS contains a standardized combination of the plants namely Glycyrrhiza glabra, Thymus vulgaris, Alpinia officinarum, Vitis vinifera, and Urtica dioica. The hemostatic effect of ABS depends upon the quick promotion of a protein network, particularly fibrinogen gamma, in relation to the erythrocyte aggregation. The aim of this review is to indicate pharmacobiological basis and clinical backgrounds of ABS. Current perspective for using ABS is to provide hemostasis and accelerating wound healing particularly in cases which are difficult to manage. Future controlled trials are needed to elucidate the actions of ABS with in hemostasis, antithrombotic, anti-inflammatory, anti-infective, antifungal, and anti-oxidative effects.
