Online health information seeking behavior, healthcare access, and health status during exceptional times.

Online health information seeking behavior (e-HISB) is becoming increasingly common and the trend has accelerated as a result of the COVID-19 pandemic when individuals strongly relied upon the Internet to stay informed by becoming exposed to a wider array of health information. Despite e-HISB having become a global trend, very few empirical investigations have analyzed its potential influence on healthcare access and individuals' health status. In this paper, we try to fill this gap.

The impact of different levels of functional oil supplementation in combination with salinomycin on growth performance and intestinal microbiota of broilers undergoing Eimeria challenge: An analysis of dynamics.

The effect of salinomycin sodium alone and in combination with functional oils on performance and microbiota of broiler infected Eimeria were evaluated. 512 broilers were randomly assigned to 4 treatments (8 replicates, 16 birds/pen): a Control group (any additives); Ionophore group: salinomycin supplementation at 66 ppm (SS66); Ionophore +0.075% Functional oil (FO) group (SS66 + FO supplementation at 750 ppm); and Ionophore +0.

Overseas general practitioners (GPs) and prescription behaviour in England.

The UK imports many doctors from abroad, where medical training and experience may differ. This study aims to understand how drug prescription behaviour varies in English GP practices with higher shares of foreign-trained GPs. Results indicate that in general prac- tices with a high proportion of GPs trained outside the UK, there are higher prescriptions for antibiotics, mental health medication, analgesics, antacids, and statins, while controlling for patient and practice characteristics.

Effect of live Eimeria vaccination or salinomycin on growth and immune status in broiler chickens receiving in-feed inclusion of gelatin and vitamin E.

This experiment determined if 2% of gelatin, to improve the levels of proline and glycine in the diet, and 70 mg/kg of vitamin E supplementation would relieve the impaired performance of male Cobb broilers vaccinated for coccidiosis. Half of the chicks were vaccinated via water (live oocysts), while the other half received medication (salinomycin) in the feed until 35 d of age. The effects of coccidiosis vaccine on performance and mRNA levels of genes involved in mucin synthesis, cytokines, trefoil family factor-2 (TFF2), and metabolic processes (CD36) in the jejunum of broilers were measured.

Trends in inequality of opportunity in health over the life cycle: The role of early-life conditions.

This paper explores the evolution of inequality of opportunity in the prevalence of chronic diseases along the life cycle and across different birth cohorts for individuals aged 50 or older and residing in 13 European countries. We adopt an ex-ante parametric approach and rely on the dissimilarity index as our reference inequality metric. In addition to a commonly used set of circumstances, we pay particular attention to the role of adverse early-life conditions, such as the experience of harm and the quality of the relationship with parents.

Visiting parents in times of COVID-19: The impact of parent-adult child contacts on the psychological health of the elderly.

Using the 8th wave of the SHARE and the SHARE Corona Survey, we investigated whether the disruption of parent-adult child contacts due to social distancing restrictions increased the symptoms of depression among old age individuals during the first wave of the COVID-19 pandemic. We model the relationship between the disruption of parent-adult child contacts and the mental health of the elderly using a recursive simultaneous equation model for binary variables. Our findings show that the likelihood of disruption of parent-adult child contacts was higher with adult children who do not live with or close to their parents (i.

Changes in the ceca microbiota of broilers vaccinated for coccidiosis or supplemented with salinomycin.

The objective of this study was to characterize differences in the cecal microbiota of chickens vaccinated for coccidiosis or receiving salinomycin in the diet. In this study, 140 male 1-day-old broiler chickens were divided in 2 groups: vaccine group (live vaccine) vaccinated at the first day and salinomycin group (125 ppm/kg since the first day until 35 d of age). Each treatment was composed for 7 replicates of 10 birds per pen.

Dietary osteopontin-enriched algal protein as nutritional support in weaned pigs infected with F18-fimbriated enterotoxigenic Escherichia coli.

This study investigated the effects of dietary osteopontin (OPN)-enriched algal protein on growth, immune status, and fecal fermentation profiles of weaned pigs challenged with a live infection of F18-fimbriated enterotoxigenic E. coli (ETEC). At 21 d of age, 54 pigs (5.

Effect of early feed restriction programs and genetic strain on humoral immune response production in broiler chickens.

Two experiments were conducted to compare the immunocompetence of Cobb high performance and rustic Label Rouge broilers and the influence of reduced growth rates subsequent to feed restriction on the IgY anti-bovine serum albumin (BSA) response. In the first experiment (EXP), 360 broilers were assigned to 36 cages from 1 to 42 days of age. A completely randomized design was applied in a 3 × 2 factorial arrangement, with 3 groups (Label Rouge, Cobb ad libitum, and Cobb Restricted Intake), and 2 levels of energy (3,100 and 2,800 kcal/kg); there were 6 replicates per treatment.

Demand of long-term care and benefit eligibility across European countries.

In this paper, we study how elderly individuals adjust their informal long-term care utilization to changes in the provision of formal care. Despite this is crucial to design effective policies of formal elderly care, empirical evidence is scant due to the lack of credible identification strategies to account for the endogeneity of formal care. We propose a novel instrument, an index that captures individuals' eligibility status for the long-term care programs implemented in the region of residence.

Impact of RANTES, MCP-1 and IL-8 in mast cells.

Chemokines are cytokines with chemotactic properties on inflammatory cells and other cell types. RANTES, MCP-1 and related molecules, constitute the C-C class of chemokine supergene family and a group of cytokines produced by hematopoietic cells, while IL-8 constitute the C-X-C class. The roles of most of these chemokines are not well known, although members of the chemokine family are inflammatory agents.

Infections and mast cells.

Mast cells play a role in various physiological functions: innate and acquired immunity, epithelium remodelling and proliferation, angiogenesis, cancer, inflammation and infections. Mast cells are activated by cross-linking of FcERI molecules, which are involved in the binding of multivalent antigens to the attached IgE molecules, resulting in a variety of responses including the immediate release of potent inflammatory mediators. In addition, mast cell biology consists in the capability to secrete preformed mediators which include biogenic amines and newly synthetized mediators, which include lipid-derived mediators and cytokines.

Neuropeptide substance P induces mRNA expression and secretion of CXCL8 chemokine, and HDC in human umbilical cord blood mast cells.

Purpose: Mast cells play an important role in innate and acquired immunity and are thought to be the cellular origin of most proteases and cytokines. Substance P (SP) and its receptor, NK-1R, play critical roles in immune regulation in human and animal models of inflammation.

Methods: We used mature human cord blood mast cells (HCBMC) differentiated from cord blood CD34+ precursor activated with SP in culture.

Mast cells and chemokines.

Chemokines are small proteins (8-12 kD polypeptides) secreted by the cells of innate and adaptive immunity that mediate many of the functions of these cells, including recruitment of other cells. They are classified into families: CC, CXC and CX3C. CXC chemoattract mainly on neutrophils and CC act mainly on monocytes, eosinophils and mast cells.

Impact of substance P on cellular immunity.

Much evidence suggests a cross-talking between nerve fibers and the immunity system. The immunomodulation by substance P includes cell activation and proliferation of human cells, with cytokine and chemokine generation and release. Substance P was first isolated by Leeman et al.

Biology of neurotensin: revisited study.

The tridecapeptide neurotensin (NT) acts in the mammalian brain as a primary neurotransmitter or neuromodulator of classical neurotransmitters. Morphological and functional in vitro and in vivo studies have demonstrated the existence of close interactions between NT and dopamine both in limbic and in striatal brain regions. Additionally, biochemical and neurochemical evidence indicates that in these brain regions NT also plays a crucial role in the regulation of the aminoacidergic signalling.

Poly-L-lactic acid beta-tricalcium phosphate screws: a preliminary in vivo biocompatibility study.

The aim of this study is to assess the biocompatibility of two types of Poly-L-lactic acid (PLLA) screws (with either hydroxyapatite (HA) or beta-tricalcium phosphate (beta-TCP)) implanted in the left femur of four sheep euthanized at 42, 50, 57 and 84 days after surgery. Titanium screws were also implanted for comparison purposes. No signs of inflammation were seen in the 240 specimens.

Effects of anterior cruciate ligament (ACL) injury on postural control and muscle activity of head, neck and trunk muscles.

The aim of the study was to evaluate the effects that an anterior cruciate ligament injury of the knee has on postural control and activity of neck, head and trunk muscles to investigate the existence of connections between the masticatory system and body posture. Surface electromyographic activity of the muscles at mandibular rest position, and during maximal voluntary clenching and posturometric and stabilometric measurements of 25 adult patients having pathology on the left knee were compared with a control non-pathological group. At rest, the patients showed a higher muscular activity of anterior temporalis, masseter, sternocleidomastoid and lower trapezius, compared with the control subjects (P < 0.

Arthroscopic treatment of post-traumatic elbow stiffness.

Aim: The treatment of post-traumatic elbow stiffness has seen many important changes over the years, particularly through the development of arthroscopy, greater knowledge of anatomy and improvements in operative techniques, that reduce the incidence of complications and facilitate postoperative recovery. In this study mid-term clinical results of arthroscopy for post-traumatic elbow stiffness are evaluated in 15 sporting patients, with an average age of 32 years.

Methods: Eight patients reported post-traumatic stiffness due to fracture of the radial head, 3 to fracture-dislocation, 1 to fracture of the radial diaphysis complicated by osteosynthesis, and the remaining 3 patients to stress syndromes with osteochondral detachment.

Influence of knee pathology on body posture and muscle activity of head, neck and trunk muscles.

Aim: The aim of the study was to evaluate the effects that an anterior cruciate ligament (ACL) injury of the knee has on postural control and activity of neck, head and trunk muscles in order to investigate the existence of connections between the masticatory system and body posture.

Methods: Surface electromyographic (sEMG) activity of the muscles and their asymmetry index, at mandibular rest position, and during maximal voluntary clenching (MVC), and posturometric and stabilometric measurements of 25 patients (mean age 28+/-9 years) having undergone ACL injury of the left knee were compared with a control non-pathologic group.

Results: At rest, the patients showed a higher sEMG activity of the anterior temporalis, masseter, sternocleidomastoid and lower trapezius, compared with the control subjects (P<0.

Contraceptive counseling in managed care: preventing unintended pregnancy in adults.

This study examines contraceptive counseling received by adult women in their managed care plans and the relationship between counseling and women's contraceptive attitudes and practices. Telephone interviews were conducted with a random sample of 898 women ages 18 to 44 enrolled in a commercial health maintenance organization (HMO) or point-of-service (POS) health plan. Counseling received in the past 2 years was measured on three dimensions: exposure through any communication channel; content of information; and personalization of discussion.
