Long-term results for post-interventional systemic heparinization following angioplasty of peripheral vessels

Published on: 15th June, 2020

OCLC Number/Unique Identifier: 8612480354

Objective: The long-term outcome of percutaneous transluminal angioplasties is mainly determined by restenoses, either by progression of the underlying disease or by intimal hyperplasia. Pharmacological substances on the one hand and the implantation of stents on the other have been developed with the intention of preventing precisely this complication. While patients are treated after PTA of peripheral vessels with different low-molecular-weight heparins, the indication for stent implantation is determined individually rather by experience. The aim of this study was to determine gender-specific risk factors of long-term outcome after percutaneous transluminal angioplasty (PTA) of peripheral vessels with or without stentimplantation. Methods: In the present study, we examined the long-term results of percutaneous transluminal angioplasty (PTA) of peripheral vessels. Between 2007 and 2017, in total, 3,276 patients underwent PTA with or without stent implantation in our clinic. All patients were treated postinterventionally for 48 hours with 25,000 IU heparin (Unfractionated Heparin (UFH), heparinsodium-Braun, 25,000 I.E./5 ml, 2 ml/h) monitored by the partial thromboplastin time and subsequently underwent a control investigation every 6 months. The endpoint of the study was determination of symptomatic stenosis larger than 50% that required reintervention. Results: 239 (68.2% with mean age 68.02 years) male patients and 111 female patients (31.71% with mean age 62.92 years) were evaluated with complete follow-up. A total of 470 PTAs were performed on male patients and 213 on female patients in multiple interventions. The majority of patients at the time of treatment were in stage IIb according to the classification of Fontaine (81.6% of male patients and 68% of females). In our sample, peripheral arterial disease stage III and IV according to Fontaine classification occurred twice as frequently in female patients as in male patients (stage III in 12.6% in female versus 6.1% in male, and stage IV in 18% in female versus 8.9% in males). In both groups, the femoral superficialis artery was most frequently dilated (64 cases, 30% in female and 155 cases, 32.9% in male), followed by the iliacal communis artery (46 cases in female and 99 cases in male, both with 21.5%). A balloon angioplasty of the tibialis anterior and posterior arteries was performed twice as frequently in female patients as in male patients (28 cases with 13.1% of tibialis ant. artery in female versus 32 cases with 6.8% in male patients, and in 17 cases with 7.9% of tibialis post. artery in female versus 16 cases with 3.4% in male patients). In this study, without consideration of gender, patency rates of 79% after 2.5 years, 67% after 5 years, 49% after 7.5 years and 37% after 10 years were determined for PTA without stent implantation. Between the 7th and 10th year in follow-up, the cumulative patency rates for stent implantation was 49%, whereas it was 31% for PTA alone. The results of this study show that the stent assisted PTA`s of comm. artery and external iliacal artery are significantly independent of risk factors better than the femoral vessels, and these in female patients better than in male patients. Male patients do not benefit significantly from stent implantation in the long term. As the COXI and II regression analyses show, gender-linked results are most evident for renal insufficiency and diabetes mellitus, and less pronounced also for the number of open lower leg vessels. Conclusion: Under consideration of gender and risk factors, while male patients with diabetes mellitus, renal insufficiency and/or poor run-off did not benefit from stent implantation in the long-term, female patients with similar risk factors showed higher patency rates after stent therapy. In addition, the long-term results after PTA of femoral superficialis artery and poplitea artery are significantly worse than PTA of the pelvic vessels in both genders.

Fibrinolytic therapy with tPA failed because it was based on a flawed concept

Published on: 16th June, 2020

OCLC Number/Unique Identifier: 8628672035

Fibrinolytic therapy has become synonymous with tissue plasminogen activator (tPA) based on the belief that tPA alone was responsible for natural fibrinolysis. Although this assumption was belied from the outset by disappointing clinical results, it persisted, eventually causing fibrinolysis to be discredited and replaced by an endovascular procedure. Since time to reperfusion is the critical determinant of outcome, which in acute myocardial infarction (AMI) means within two hours, a time-consuming hospital procedure is ill-suited as first line treatment. For this purpose, fibrinolysis is more fitting. The assumption that tPA is responsible for fibrinolysis is contradicted by published findings. Instead, tPA ‘s function is limited to the initiation of fibrinolysis, which is continued by urokinase plasminogen activator (uPA) and that has the dominant effect. tPA and uPA gene deletion and clot lysis studies showed the activators have complementary functions, requiring both for a full effect at fibrin-specific doses. They are also synergistic in combination thereby requiring lower doses for efficacy. A clinical proof of concept study in 101 AMI patients who were treated with a 5 mg bolus of tPA followed by a 90 minute infusion of prouPA, the native form of uPA. A near doubling of the 24 h TIMI-3 infarct artery patency rate was obtained compared to that in the best of the tPA trials (GUSTO). In further contrast to tPA, there were no reocclusions and the mortality was only 1% [1]. A sequential combination of both activators, mimicking natural fibrinolysis, holds promise to significantly improve the efficacy and safety of therapeutic fibrinolysis.

Influenza B myositis, case report, in hospital Roosevelt, Guatemala city

Published on: 11th March, 2023

Influenza B myositis is a self-limited process that is typically accompanied by myalgia and muscle weakness, which can be caused by an acute respiratory infection. It occurs in the convalescence phase of the disease. It can usually affect preschool and school children, who present bilateral pain and tenderness in the muscle groups of the lower limbs without alterations in the neurological examination. Being able to generate an alteration in the brand or bipedestation. Its main complication is rhabdomyolysis. In Guatemala is difficult to test for viral respiratory infection and the incidence of viral myositis is unknown, for which we consider the report important because it presents a benign course and is easy to manage with the use of non-steroidal anti-inflammatory drugs, to avoid unnecessary hospitalizations. We present to case report to an 8-year-old male patient, previously healthy, with diagnostic de Influenza B myositis.

Effects of melatonin on liver and lung tissues of animals with bile duct ligation-induced hepatopulmonary syndrome

Published on: 13th October, 2021

OCLC Number/Unique Identifier: 9305372985

The objective was to assess the antioxidant effect of melatonin (MLT) on liver and lung tissues of animals with bile duct ligation (BDL)-induced hepato-pulmonary syndrome (HPS). A model of BDL-induced biliary cirrhosis was used in male Wistar rats. Results suggest that MLT has an antioxidant effect on liver and lung tissues in animals with BDL-induced HPS by higher activity of antioxidant enzymes in the group HPS treated with MLT and the histological analysis of lung parenchyma showing decreased damage in this same group, including other analysis described below.

The factors associated with mental health and the impact of COVID-19

Published on: 11th August, 2022

OCLC Number/Unique Identifier: 9591348162

The mental health impact caused by COVID-19 on adolescents was reviewed, and due to limited data, adult results were included, to support our assertion that additional mental health resources are needed for both adult and young people. Positive gains would include improved socio-emotional skills, a decrease in maladaptive behaviors contributing to the disruption in interpersonal relationships and lifetime achievements, suicide attempts and psychopathology, persistent mental health concerns found in the juvenile justice and foster care systems and substance use addiction later in adulthood (The American Psychological Association, 2019; Garber & Weersing, 2010; Office of Juvenile Justice and Delinquency Prevention, n.d.; Tomasello, 2018;). Geiger & Davis, 2019, found that 13% or 3.2 million United States (U.S.) teenagers aged 12 - 17 years old experienced at least one major depressive episode with the depression rate increasing 59% from 2007 to 2017. Therefore, we assert that developing programs to overcome barriers to mental health aid can reduce instances experienced in adolescence and adulthood.

Requirement for object-oriented database management systems in forensic science

Published on: 21st March, 2023

The complex requirements of a database system for recording regulated chemicals exceed the capabilities of a relational database system. Inheritance, which is part of object-oriented programming, must also be logically transferred to chemical objects. This issue is illustrated here by means of examples of the Chemical Weapons Convention (CWC) and the German version of the New Psychoactive Substances Law (NpSG).

Pre-eminence and comparative analysis of skin and surface disinfectants: A systematic review to pave the way for SARS-CoV-2 prevention

Published on: 29th April, 2021

OCLC Number/Unique Identifier: 9023195512

More than 200 countries have been devastated by the SARS-CoV-2 pandemic. The health workers exposed to SARS patients have been confirmed to be infected with coronavirus (SARS-CoV-2), regardless of the degree of their exposure. The increasing complexity of virus existence and heterogeneity has cast doubt on disinfectants as a viable choice. Hence, the present systematic review aims to achieve the comparative analysis of established disinfectants against enveloped and non-enveloped viruses including SARS-CoV and MERS-CoV. Three databases (Pubmed, Google scholar, and Medline) were searched to frame the systematic review. Our comparative analyses with 34 studies have found that 85% ethanol-based hand sanitizers and 7.5% Povidine Iodine based soaps/surgical scrub could be used to deter the SARS-CoV-2 virus as preferred hand sanitizers. For surface eradication, 0.5% sodium hypochlorite or a mixture of glutaraldehyde, Quaternary Ammonium Compounds (QAC), and isopropanol could have more efficacies as compared to hydrogen peroxide, phenol, and QAC alone. Moreover, the accelerated hydrogen peroxide as an active ingredient in the automatic quick surface disinfectant (tunnel system), maybe a positive indication for quick whole-body sanitation. Additionally, the alternative method for avoiding the rapidly increasing chain of infection with SARS and restarting regular life has been exclusively discussed.

Quality of life in Ghanaian children and adolescents with type 1 diabetes mellitus compared with non diabetic controls and caregivers’ report

Published on: 30th March, 2023

Background: Measurement of health-related quality of life (HRQOL) in children and adolescents with type 1 diabetes mellitus (T1DM) is as important as metabolic control in the management and prevention of diabetes-related complications. Aim: To describe the self-reported HRQOL outcomes in Ghanaian children and adolescents with T1DM compared with healthy controls and perceived HRQOL by caregivers.Setting: Out-patient clinics of the Departments of Child Health, Medicine and Therapeutics, Family Medicine, and Ophthalmology, the National Diabetes Management and Research Centre (all at the Korle Bu Teaching Hospital), and the Cape Coast Teaching Hospital (CCTH).Methods: Socio-demographic and clinical characteristics of study participants were documented. Participants completed the PedsQL™ 4.0 Generic Core Scales. Data analysis was done with SPSS Version 25.0. An unpaired t-test was used in comparing the HRQOL scores between children and adolescents with T1DM and controls, and parental proxy reports. Results: Fifty children and adolescents with T1DM, 50 parents/caregivers, and 80 healthy non-diabetic controls took part in this study. There was no significant difference in mean score between the patients and the caregivers for overall HRQOL (p = 0.270). Patients reported significantly worse overall HRQOL than their controls (p = 0.001). Males with diabetes reported better HRQOL than females (p = 0.007). Conclusion: Children and adolescents with T1DM and their parents/caregivers reported lower HRQOL scores compared to healthy controls. Males reported better HRQOL than females. Potential implications: HRQOL should be routinely assessed together with proxy reports from parents to identify those who might benefit from further attention including referral to a psychologist.

Investigation of Malpractice Claims Concerning Orthopedic Surgeons in Sari, North of Iran, 2015-2020

Published on: 17th October, 2023

Introduction: Treatment failure and claims against physicians may have many negative consequences. Orthopedic surgeons have always been among the most used specialists. Therefore, the investigation of causes and the process of these claims can help reduce the negative effects of medical malpractice on physicians and society.Materials and methods: This retrospective study investigated all medical orthopedic negligence cases in Sari, Iran, from March 2015 to March 2020. Data were collected using a researcher-made checklist and analyzed in SPSS software (V-21).Results: Out of 57 finalized cases investigated in this study, surgeons were found liable in 23 (40%) cases. The mean ± SD age of patients was 41 ± 19.3. Moreover, the level of education had a positive correlation with the surgeon’s liability. The most common cause of complaint was reduced Range of motion (ROM) and the most common type of complained surgery was “open reduction & internal fixation” (ORIF). None of the surgeons were found liable due to surgical site infection or device failure. The mean ± SD time for the file processing was 11.1 ± 10.1 months. The mean indemnity payment was 320 million Iranian Rials (9.7% of indemnity for death in Iran).Conclusion: The most effective way to reduce medical complaint cases is to increase the knowledge and skill levels of physicians. The lack of a blinded arbitration system in both organizations could lead to bias in the case assessment process. Moreover, considering the long processing time of the claims, it is recommended that new technologies should be used to reduce the time and increase the accuracy of the final verdict. The absence of a ‘no-fault’ compensation program is a significant flaw in Iran violating patients’ rights. Also, more studies are needed to evaluate justice and equality in Iranian medical commissions.
