Effects of the prolonged thoracic epidural analgesia on ventilation function and complication rate after the lung cancer surgery.
2006
Thoracic epidural analgesia has been considered to have a good anesthetic efficacy and to decrease the postoperative complication rate, while its effect upon the ventilation function is still the topic of many clinical studies. The aim of this study was to evaluate the course of early postoperative period using thoracic epidural analgesia. Material and methods. A total of 453 patients undergoing the operation due to the non–small cell carcinoma were selected and examined. Their postoperative complications and mortality rate were evaluated. In 79 patients, arterial oxygen saturation (SaO2), forced vital capacity, forced expiratory volume in the first second, and the efficacy of analgesia wer…
Stiff landings are associated with increased ACL injury risk in young female basketball and floorball players
2016
Background: Few prospective studies have investigated the biomechanical risk factors of anterior cruciate ligament (ACL) injury. Purpose: To investigate the relationship between biomechanical characteristics of vertical drop jump (VDJ) performance and the risk of ACL injury in young female basketball and floorball players. Study Design: Cohort study; Level of evidence, 3. Methods: At baseline, a total of 171 female basketball and floorball players (age range, 12-21 years) participated in a VDJ test using 3-dimensional motion analysis. The following biomechanical variables were analyzed: (1) knee valgus angle at initial contact (IC), (2) peak knee abduction moment, (3) knee flexion angle at …
Prescribing behaviour of practitioners in public and private hospitals in Pakistan evaluated using the World Health Organization (WHO) indicators: A …
2017
Summary Introduction The non-rational use of medicines by medical practitioner in their prescribing practices might lead to therapeutic failure. The aim of this research was to evaluate medical prescriptions and to highlight differences in behaviour between prescribers of public and private hospitals in Karachi (Pakistan). Materials and methods This is a retrospective study conducted between November 2015 to October 2016 in 4 public hospitals and 4 private hospitals in Karachi. A total of 120,096 (n) prescriptions were collected from both public and private hospitals. The data were evaluated with WHO indicators for rational use of medicines. Results The average number of drugs per prescript…
No findings of dental defects in children treated with minocycline
2004
Thanks to their broad antimicrobial spectrum, tetracyclines were found to be valuable for the treatment of many infections (10). Unfortunately, they irreversibly bind to calcifying tissues and are deposited along the incremental lines of dentine and enamel, causing defects and staining, from bright yellow to dark brown (3, 5, 8). According to the American Academy of Pediatrics, tetracyclines are not indicated for the treatment of common infections in children younger than 8 years of age. However, doxycycline (a tetracycline analogue) is recommended for treatment of Rocky Mountain spotted fever in children of any age (1). Minocycline has several advantages over other tetracyclines: it is bet…
Oxidative stress in preterm infants: Overview of current evidence and future prospects
2020
Preterm birth (PTB), defined as parturition prior to 37 weeks of gestation, is the leading cause of morbidity and mortality in the neonatal population. The incidence and severity of complications of prematurity increase with decreasing gestational age and birthweight. The aim of this review study is to select the most current evidence on the role of oxidative stress in the onset of preterm complication prevention strategies and treatment options with pre-clinical and clinical trials. We also provide a literature review of primary and secondary studies on the role of oxidative stress in preterm infants and its eventual treatment in prematurity diseases. We conducted a systematic literature s…
A Machine Learning Model to Predict Intravenous Immunoglobulin-Resistant Kawasaki Disease Patients: A Retrospective Study Based on the Chongqing Popu…
2021
Objective: We explored the risk factors for intravenous immunoglobulin (IVIG) resistance in children with Kawasaki disease (KD) and constructed a prediction model based on machine learning algorithms.Methods: A retrospective study including 1,398 KD patients hospitalized in 7 affiliated hospitals of Chongqing Medical University from January 2015 to August 2020 was conducted. All patients were divided into IVIG-responsive and IVIG-resistant groups, which were randomly divided into training and validation sets. The independent risk factors were determined using logistic regression analysis. Logistic regression nomograms, support vector machine (SVM), XGBoost and LightGBM prediction models wer…
Possible Role of the Posterior Compartment Peritonectomy, as a Part of the Complex Surgery, Regarding Recurrence Rate, Improvement of Symptoms and Fe…
2020
ABSTRACT Study Objective Beside the pain, there are 2 further problems in the management of endometriosis: the high recurrence rate (10% per year) and the high rate of impaired fertility. The objective of this study was to investigate the pathogenesis of these 2 factors. Design This is a retrospective cohort study, and the aim is to evaluate the complete excision of endometriotic lesions, including the posterior compartment of the peritoneum, with regard to postoperative outcome, focusing on relieving pain, increasing fertility rate, and decreasing recurrence rate. Setting Charite-University Clinic, Department of Gynaecology, Endometriosis research Centre. Patients Fifty-four patients were …
Objectively recorded physical activity and the association with gestational diabetes
2014
The aim of this population-based study was to assess the association between objectively recorded physical activity (PA) in early gestation and gestational diabetes mellitus (GDM) identified at 28 weeks of gestation in a multi-ethnic cohort of healthy pregnant women in Oslo, Norway. In total, 759 women were included. In early gestation (<20 weeks), light-, moderate-, and vigorous-intensity PA and number of steps were objectively recorded (SenseWear™ Armband Pro3), and self-reported PA, demographics, and anthropometrics were collected. The 75-g oral glucose tolerance test was performed at 28 weeks of gestation. Women with GDM had fewer objectively recorded steps (mean 7964 steps/day vs 8879 …
Glatiramer acetate during early pregnancy: A prospective cohort study
2016
Background: Only limited data are available on whether glatiramer acetate exposure during pregnancy has an effect on perinatal outcome. Objective: To determine the effect of glatiramer acetate exposure during pregnancy on pregnancy outcomes in women with multiple sclerosis. Methods: We compared the outcome of pregnancies of women with multiple sclerosis exposed to glatiramer acetate with pregnancies unexposed to disease-modifying therapies. Women were enrolled into the German Multiple Sclerosis and Pregnancy registry. A standardized questionnaire was administered during pregnancy and postpartum. Detailed information on course of multiple sclerosis and pregnancy, concomitant medications, lab…
