This study provides a contemporary epidemiology of aspirates taken during surgery from the abdominal cavity among patients with bacterial peritonitis to identify the isolates and study their sensitivity to antibiotics. Our bacteriology investigations included isolation of poor cultures, and detection of microbes was conducted using a rapid identification system (API20E, API Staph, API Strep, API Ana, BioMerieux). Rapid tests for detection of oxidase and catalase activity were also used. Susceptibility of microorganisms to antibiotics was defined by the disc-diffusion method using standard discs (EUCAST guidelines 2015) according to Clinical Laboratory Standard Institute (CLSI) protocols (ATB strips: ATB G, ATB Staph, ATBANA, ATBPse, ATBStrep...

Diabetes mellitus (DM) is associated with cardiovascular complications. Impairment of glycemic control induces noxious glycations, an increase in oxydative stress and dearangement of various metabolic pathways. DM leads to dysfunction of micro and macrovessels, connected to metabolic, endothelial and autonomic nervous system. Thus, assessing vascular reactivity might be one of the clinical tools to evaluate the impact of harmful effects of DM and potential benefit of treatment; skin and skeletal muscle microcirculation have usually been tested...

Nitric oxide (NO) is a toxic free radical produced by neutrophils and macrophages in response to infection. Uropathogenic Escherichia coli (UPEC) induces a variety of defence mechanisms in response to NO, including direct NO detoxification (Hmp, NorVW, NrfA), iron-sulphur cluster repair (YtfE), and the expression of the NO-tolerant cytochrome bd-I respiratory oxidase (CydAB). The current study quantifies the relative contribution of these systems to UPEC growth and survival during infection. Loss of the flavohemoglobin Hmp and cytochrome bd-I elicit the greatest sensitivity to NO-mediated growth inhibition, whereas all but the periplasmic nitrite reductase NrfA provide protection against neutrophil killing and promote survival within activated macrophages...

BACKGROUND: Extreme conditioning programs (ECPs) are fitness training regimens relying on aerobic, plyometric, and resistance training exercises, often with high levels of intensity for a short duration of time. These programs have grown rapidly in popularity in recent years, but science describing the safety profile of these programs is lacking. HYPOTHESIS: The rate of injury in the extreme conditioning program is greater than the injury rate of weightlifting and the majority of injuries occur to the shoulder and back...

PURPOSE: Updated cardiac rehabilitation (CR) and return-to-work guidelines from the American College of Sports Medicine (ACSM) now include specificity of training for industrial athletes (exercise training that involves the muscle groups, movements, and energy systems that these patients use during occupational tasks). However, many CR facilities do not apply this principle, relying instead on the traditional protocol that consists primarily of aerobic exercise. This study was conducted to measure the metabolic cost of typical farming tasks and to compare 2 methods of calculating training intensities...

A plethora of evidence exists supporting that structured aerobic exercise or activities that increase cardiorespiratory fitness (CRF) lower resting blood pressure (BP) in patients with hypertension (HTN). Relatively few studies have assessed the effects of anaerobic or resistance exercise on BP. Thus, its role in managing HTN is not defined. Also, possible risks related with exercise in hypertensive patients have not been adequately addressed.In addition to lowering BP, CRF attenuates the incidence of HTN. A substantial part of the age-related progression to HTN is not an inevitable outcome of aging as once thought, but a consequence of lifestyle characterized by high-fat/salt diets and physical inactivity...

Cardiovascular diseases (CVD) are major causes of death and illness worldwide. In recent decades an increased prevalence of CVD mortality has been reported in low-medium income countries, which has been associated with changes in life styles, deficiencies in health systems and the persistence of social inequities.The metabolic syndrome comprises a cluster of cardiometabolic risk factors, with insulin resistance and increased adiposity as its central features. Identifying individuals with metabolic syndrome is important due to its association with an increased risk of coronary heart disease and type 2 diabetes mellitus (DM2)...

Previously it has been reported that reduced-exertion high-intensity interval training (REHIT; total training time of 3 × 10 min per week) improves maximal aerobic capacity in both sedentary men and women, but improves insulin sensitivity in men only. The aim of the present study was to determine whether there is a true sex difference in response to REHIT, or that these findings can be explained by the large interindividual variability in response inherent to all exercise training. Thirty-five sedentary participants (18 women; mean ± SD age for men and women, respectively: age, 33 ± 9 and 36 ± 9 years; body mass index, 25...
