Consequences of neonatal resuscitation with supplemental oxygen.
2008
There has been considerable controversy surrounding the optimal inspired oxygen concentration for resuscitation of term and preterm infants. We have developed a rat pup model to quantify both physiologic and biochemical parameters associated with normoxic vs. hyperoxic resuscitation. We have confirmed existing human data that hyperoxic resuscitation of rat pups is associated with a significant delay in onset of spontaneous respiratory efforts. Both 40% and 100% inspired oxygen delayed onset of respiratory activity when compared to 21% oxygen. We have also documented, in the rat pup model, that hyperoxic resuscitation is associated with reduced levels of glutathione at 24 hours post resuscit…
Alpha-adrenergic drugs in retrograde ejaculation.
1974
6 men with complete or partial loss of ejaculation as a result of retroperitoneal lymphadenectomy (performed because of testicular tumor) were treated with an intravenous injection of 60 mg synephrine. Synephrine stimulates adrenergic alpha-receptors. Only 1 man with sustained retrograde ejaculation improved following treatment showing antegrade ejaculation. This temporary restoration of fertility was thought to be due to an increase in bladder neck tone and prevention of backflow of semen into the bladder as a result of stimulation of adrenergic alpha-receptors.
Pulmonary hypertension in pediatrics. a feasible approach to bridge the gap between real world and guidelines
2019
Pulmonary hypertension (PH) is quite infrequent in pediatric age and its most common etiologies include idiopathic pulmonary arterial hypertension, PH related to congenital heart diseases, bronchopulmonary dysplasia (chronic lung disease), persistence of pulmonary hypertension of the newborn, and congenital diaphragmatic hernia. The developed for adult patients PH classification shows limitations when applied to pediatric subjects since the underlying causes are markedly different between the two ages. In 2011, the Pulmonary Vascular Research Institute Panama Task Force outlined the first specific pediatric pulmonary hypertensive vascular disease diagnostic classification, including 10 main…
AISF position paper on liver transplantation and pregnancy: Women in Hepatology Group, Italian Association for the Study of the Liver (AISF)
2016
After the first successful pregnancy in a liver transplant recipient in 1978, much evidence has accumulated on the course, outcomes and management strategies of pregnancy following liver transplantation. Generally, liver transplantation restores sexual function and fertility as early as a few months after transplant. Considering that one third of all liver transplant recipients are women, that approximately one-third of them are of reproductive age (18-49 years), and that 15% of female liver transplant recipients are paediatric patients who have a >70% probability of reaching reproductive age, the issue of pregnancy after liver transplantation is rather relevant, and obstetricians, paedi…
Effect of a 1-year elastic band resistance exercise program on cardiovascular risk profile in postmenopausal women
2018
Objective: The aim of this study was to investigate the effects of a 1-year progressive resistance training program using elastic bands on cardiovascular profile parameters in sedentary postmenopausal (>12 months’ amenorrhea) women. Methods: This longitudinal prospective experimental study included 38 menopausal women who were randomly divided into two groups: an intervention group (IG, n = 18), who completed a progressive resistance training program with elastic bands over the course of 12 months (six exercises for whole body training, three sets × 10 repetitions), and a control group (CG, n = 20) that did not perform any training. Blood analysis and body composition were determined at bas…
Realizing women´s right to maternal health: A study of awareness of rights and utilization of maternal health services among reproductive age women i…
2019
BackgroundMaternal mortality rates are still unacceptably high in many countries, indicating violation of women´s human right to life and health. Access to adequate information about maternal health rights and available services are essential aspects of realizing women´s right to accessible health care. This study aimed at assessing awareness of the right to access maternal health services among women who had recently given birth, and the association between such awareness and the utilization of maternal health services in two districts in Tanzania.MethodsThis study was cross sectional in design. Interviews were conducted with women who gave birth within one year prior to the survey in two …
Inflammation and sarcopenia: A systematic review and meta-analysis
2017
Inflammatory cytokines have been shown to prompt muscle wasting, ultimately stimulating protein catabolism and suppressing muscle synthesis. However, the possible association between inflammatory parameters and sarcopenia is poorly understood. We therefore aimed to summarize the current evidence about this topic with a meta-analysis of studies reporting serum inflammatory parameters in patients with sarcopenia vs. people without sarcopenia (controls). An electronic PubMed and Scopus search through to 09/01/2016 and meta-analysis of cross-sectional studies comparing serum levels of inflammatory cytokines between patients with sarcopenia and controls was made, calculating random-effects stand…
Factors contributing to the variability in muscle ageing
2012
a b s t r a c t Ageing is accompanied with a progressive loss of muscle mass and force generating capacity. Ultimately, the muscle wasting and weakness may dramatically impact on mobility and the quality of life, where the elderly has increasing problems with performing activities of daily life, such as rising from a chair or climbing stairs. The rate of structural and functional deterioration of muscle appears to vary considerably between people. Part of the variation in the 'rate of muscle ageing' is attributable to genetic factors, the timing of changes in circulating hormones and the presence or absence of chronic low-grade systemic inflammation. Where an individual cannot change much i…
Raloxifene increases proliferation of human endothelial cells in association with increased gene expression of cyclins A and B1.
2006
Objective To examine the proliferative effect of of raloxifene on human umbilical-vein endothelial cells (HUVECs), and to investigate whether there is an associated increased expression of some key regulators of the cell cycle. Design Cell culture for different incubation times. Setting University research laboratory. Patient(s) Sources of HUVECs. Intervention(s) Measurement of cell proliferation, of protein levels of cyclin A, cyclin B1, cyclin D1, cyclin-dependent protein kinase (CDK) 2, CDK4, and p27 Kip1 , and of messenger RNA expression of cyclin A, cyclin B1, and p27 Kip1 . Main Outcome Measure(s) Cell proliferation was measured by the 3-(4.5-dimethylthiazol-2-yl)-2,5-diphenyltetrazol…
Selective estrogen receptor modulators and risk for coronary heart disease.
2007
Coronary heart disease (CHD) is the leading cause of death in women in most countries. Atherosclerosis is the main biological process determining CHD. Clinical data support the notion that CHD is sensitive to estrogens, but debate exists concerning the effects of the hormone on atherosclerosis and its complications. Selective estrogen receptor modulators (SERMs) are compounds capable of binding the estrogen receptor to induce a functional profile distinct from estrogens. The possibility that SERMs may shift the estrogenic balance on cardiovascular risk towards a more beneficial profile has generated interest in recent years. There is considerable information on the effects of SERMs on disti…
