Factors Influencing Healthcare Utilization Among Patients at Three Free Clinics.

Despite improvements in healthcare for uninsured persons, health disparities remain. We surveyed patients at three free clinics in an urban Florida community to better understand the factors that influence where they seek healthcare. Survey questions were developed based on factors previously demonstrated to affect healthcare utilization.

Targeted Education for School Staff on Electronic Nicotine Delivery Systems: A Nurse Led Intervention.

There is a public health epidemic in adolescents' use of Electronic Nicotine Delivery Systems (ENDSs), also known as electronic cigarettes, vaping products, or JUULs. However, little is known about the level of knowledge school staff have about ENDS. The purpose of this study is to examine outcomes of a nurse-led educational intervention designed to increase school staff knowledge about ENDS.

Constraints on Cosmic Strings Using Data from the Third Advanced LIGO-Virgo Observing Run.

We search for gravitational-wave signals produced by cosmic strings in the Advanced LIGO and Virgo full O3 dataset. Search results are presented for gravitational waves produced by cosmic string loop features such as cusps, kinks, and, for the first time, kink-kink collisions. A template-based search for short-duration transient signals does not yield a detection.

Anger and confrontation during the COVID-19 pandemic: a national cross-sectional survey in the UK.

Objectives: To investigate factors associated with anger or confronting others due to COVID-19.

Design: Online cross-sectional survey.

Setting: Data were collected between 17 and 20 July 2020.

Characteristics of Microinvasive Ductal Carcinoma In Situ Versus Noninvasive and Invasive Breast Cancer.

Background: The present literature is conflicting regarding the management of microinvasive ductal carcinoma in situ (miDCIS) as to following recommendations for DCIS (margin status, surgical axillary staging, and possible observation) versus invasive breast cancer. We hypothesize that miDCIS represents more aggressive disease than pure DCIS.

Methods: We performed a retrospective review of female miDCIS patients compared with age-matched cohorts of DCIS and T1b/c patients with invasive breast cancer.

Maternity Leave Policies: Trade-Offs Between Labour Market Demands and Health Benefits for Children.

Over recent years many European Union countries have made changes to the design of the maternity leave provision. These policy developments reflect calls for greater gender equality in the workforce and more equal share of childcare responsibilities. However, while research shows that long period of leave can have negative effects on women's labour market attachment and career advancements, early return to work can be seen as a factor preventing exclusive breastfeeding, and therefore, potentially having negative health impacts for babies.

Development of the lung liquid reabsorptive mechanism in fetal sheep: synergism of triiodothyronine and hydrocortisone.

1. Thyroidectomy was performed on twelve fetal sheep between 111 and 115 days gestation. Measurement of fetal lung liquid secretion and absorption rates (Jv) were made at rest and during short (45 min) and long (5 h) infusions of adrenaline (0.

Synergistic action of triiodothyronine and hydrocortisone on epinephrine-induced reabsorption of fetal lung liquid.

The influence of triiodothyronine and hydrocortisone on maturation of the response to epinephrine that leads to reabsorption of lung liquid was investigated in nine chronically catheterized fetal sheep. Experiments were performed on thyroidectomized fetal sheep at 116-120 d gestation, well before the reabsorptive response to epinephrine is normally seen. After i.

The role of thyroid hormones in maturation of the adrenaline-sensitive lung liquid reabsorptive mechanism in fetal sheep.

1. Following thyroidectomy at 106-118 days fetal sheep were infused continuously with triiodothyronine (T3) from 110, 118, 125 or 131 days (n = 12) or with thyroxine (T4) from 118 days (n = 4) until the fetuses were delivered. Lung liquid secretion or absorption rates, heart rate, blood pressure and arterial blood gases were measured before and during 45 min periods of fetal infusions of adrenaline (n = 60) at 3-8 day intervals.

Pulmonary glucose transport in the fetal sheep.

1. In the chronically catheterized sheep fetus between 122 and 143 days gestation the concentration of D-glucose in lung liquid was very low (usually less than 0.01 mM, the lower limit of detection of the analytical method) whereas the mean plasma concentration was 0.

Solute and water transport across the pulmonary epithelium: a new chapter in lung physiology inaugurated by Alfred Jost.

Early experiments by Jost and Policard demonstrated the presence of secretory activity in the lungs of the fetal rabbit. Subsequent work has demonstrated a system of active ion transport across the pulmonary epithelium of the sheep fetus, in which uphill movement of chloride ions to the pulmonary lumen provides the main force for lung liquid secretion. In the last 10-20% of gestation a reabsorptive mechanism in response to beta-adrenergic stimulation is developed which is brought into play in the perinatal period, clearing the lungs of liquid.

The effect of thyroidectomy in the fetal sheep on lung liquid reabsorption induced by adrenaline or cyclic AMP.

1. In fetal sheep at 113-120 days' gestation, thyroidectomy was performed and tracheal, arterial and venous catheters inserted. Following a recovery period experiments were performed from 120-145 days to measure changes in lung liquid secretion or its absorption in response to I.

The role of amiloride-blockable sodium transport in adrenaline-induced lung liquid reabsorption in the fetal lamb.

Adrenaline was infused intravenously at rates of 0.1-1.0 microgram/min into chronically catheterized fetal lambs (125-141 days gestation) to induce slowing of secretion or reabsorption of lung liquid.

Effects of adrenaline and of spontaneous labour on the secretion and absorption of lung liquid in the fetal lamb.

In the chronically catheterized fetal lamb, intravenous infusion of adrenaline at 0.5 microgram/min produced slowing of the secretion of lung liquid or its absorption, an effect which increased exponentially with advancing gestation. Between 120 and 130 days, the characteristic response was slowing of secretion, whereas after 130 days it was absorption.

The permeability of lung capillary and alveolar walls as determinants of liquid movements in the lung.

The lungs of the exteriorized fetal lamb offer an unusually good opportunity for measuring the permeability of lung capillary and alveolar walls, because access to plasma, interstitial fluid and alveolar liquid can be obtained without seriously disturbing their physiological relationships. Although there are probably some differences in permeability between fetal and air-breathing lungs, the underlying pattern appears to be similar. Large water-soluble molecules, including proteins, can penetrate capillary but not alveolar walls.

Hemoglobin levels in persons of tibetan ancestry living at high altitude.

The mean hemoglobin level of persons of Tibetan ancestry living at 4000 m in the Nepal Himalayas was found similar to that expected at an altitude of 2300 m and an arterial O2 saturation of 92%. Plasma volumes were normal, and deficiency states and hemoglobinopathies were not significant. Possible reasons for this finding are discussed.
