Orthodontic treatment need in a Spanish young adult population

2011

Objectives: Orthodontic treatment need has often been assessed in child populations, but few studies employing internationally-recognized indices have been conducted in adult or young adult populations. The aim of this study was to determine the orthodontic treatment need of a young adult population in Spain by means of the Dental Aesthetic Index (DAI), the Index of Orthodontic Treatment Need (IOTN) and the need perceived by the patients. Study design: A cross-sectional epidemiological study was conducted in a broad, representative sample of 671 adults aged between 35 and 44 years using health centers in the Valencia Region of Spain, following the recommendations of the World Health Organiz…

Anxiety symptoms among informal caregivers in 47 low- and middle-income countries: A cross-sectional analysis of community-based surveys.

2022

Background-\ud \ud There are no multi-country studies on the association between informal caregiving and anxiety from low- and middle-income countries (LMICs). Therefore, we investigated this relationship in a large predominantly nationally representative sample from 47 LMICs.\ud \ud Methods-\ud \ud Cross sectional data from the World Health Survey were analyzed. Anxiety symptoms referred to severe or extreme problems with worries or anxiety in the past 30 days.\ud \ud Information on caregiving in the past 12 months was obtained. Multivariable logistic regression analysis adjusting for age, sex, marital status, education, household size, employment, disability, and country was conducted. Da…

Differential genetic determination of immune responsiveness to hepatitis B surface antigen and to hepatitis A virus: a vaccination study in twins.

2002

Summary Background The course of viral hepatitis is thought to be affected by genetic host variability and, in particular, by genes of the major histocompatibility locus. Hepatitis A and B vaccination is a useful model to study the effect of host factors on the immune response to viral antigens. We aimed to assess the heritability of the HBsAg (anti-HBs) and anti-hepatitis A virus (anti-HAV) immune response and to estimate the effect of the HLA-DRB1 locus and other genetic loci unlinked to HLA. Methods We did an open prospective study and vaccinated 202 twin pairs with a combined recombinant HBsAg/inactivated hepatitis A vaccine. We measured antibodies to HBsAg and HAV and determined HLA-DR…

Frequency and correlates of anxiety symptoms during the COVID-19 pandemic in low- and middle-income countries: A multinational study

2021

Objective Studies have documented the significant direct and indirect psychological, social, and economic consequences of the Coronavirus disease 2019 (COVID-19) in many countries but little is known on its impact in low- and middle-income countries (LMICs) already facing difficult living conditions and having vulnerable health systems that create anxiety in individuals for themselves and their loved ones. Using a multinational convenience sample from four LMICs (DR Congo, Haiti, Rwanda, and Togo), this study aims to explore the prevalence of anxiety symptoms and associated risk and protective factors during the COVID-19 pandemic. Methods A total of 1222 individuals (40.9% of women) complet…

The role of the Community Pharmacist in promoting vaccinations among general population according to the National Vaccination Plan 2017-2019: results…

2019

Introduction. The 2017-2019 Italian National Vaccination Plan promotes the improvement of knowledge and attitudes of healthcare workers about vaccine prevention, in order to spread a vaccination culture among general population. Similarly to the General Practitioner, the Pharmacist represents a fundamental forefront for both patients and healthy people, also in promoting vaccine acceptance. This research aims to analyze knowledge and attitudes about vaccines of Community Pharmacists and to evaluate the burden of vaccination counselling during their work activities. Material and methods. A standardized, self-administered and previously validated questionnaire, including 5 sections and 28 ite…

IgM and IgG antibodies to hepatitis C virus in patients with mixed cryoglobulinaemia

1993

SUMMARY To assess the relationship between hepatitis C virus (HCV) infection and essential mixed cryoglobulinaemia (EMC), sera from 23 patients with EMC were tested for IgG and IgM antibodies to HCV antigens and for HCV RNA. Quantitative HCV antibody studies were performed on scrum and purified cryoglobulin fractions. HCV antibodies of both IgG and IgM class were found in 22 (96%) patients. Ten of these were also HCV-RNA positives. Higher litres of anti-HCV IgM were present in the 11 patients with evidence of liver damage. Anti-HCV IgG antibodies were shown to be concentrated in the IgG fraction of cryoglobulins in all eight patients studied. These results strongly suggest a role for HCV in…

Immunogenicity and safety of the adjuvanted recombinant zoster vaccine in adults with haematological malignancies: a phase 3, randomised, clinical tr…

2019

BACKGROUND: The adjuvanted recombinant zoster vaccine (Shingrix) can prevent herpes zoster in older adults and autologous haemopoietic stem cell transplant recipients. We evaluated the safety and immunogenicity of this vaccine in adults with haematological malignancies receiving immunosuppressive cancer treatments. METHODS: In this phase 3, randomised, observer-blind, placebo-controlled study, done at 77 centres worldwide, we randomly assigned (1:1) patients with haematological malignancies aged 18 years and older to receive two doses of the adjuvanted recombinant zoster vaccine or placebo 1-2 months apart during or after immunosuppressive cancer treatments, and stratified participants acco…

Genetic control of immune response in carriers of the 8.1 ancestral haplotype: correlation with levels of IgG subclasses: its relevance in the pathog…

2007

Ancestral haplotype (AH) 8.1(HLA-A1, Cw7, B8, TNFAB*a2b3, TNFN*S, C2*C, Bf*s, C4A*Q0, C4B*1, DRB1*0301, DRB3*0101, DQA1*0501, DQB1*0201) seems to be associated with susceptibility to autoimmune diseases. Different mechanisms are probably involved in increasing autoimmunity, such as unbalanced cytokine production and the lack of C4A protein. So AH 8.1 modifies immune response in many ways. In this study we demonstrate that IgG2 serum levels were significantly lower in 8.1 AH carriers than in 8.1 AH non-carriers. On the contrary, as regards IgG1, IgG3, IgG4 serum levels, no significant differences were observed between the two groups. In AH 8.1 carriers low IgG2 levels might take to slower cl…

Genetic control of immune response in carriers of ancestral haplotype 8.1: the study of chemotaxis.

2007

In all caucasian populations the association of an impressive number of autoimmune diseases with genes from the HLA-B8, DR3 hap- lotype that is part of the ancestral haplotype (AH) 8.1 HLA-A1, Cw7, B8, TNFAB∗a2b3, TNFN∗S, C2∗C, Bf∗s, C4A∗Q0, C4B∗1, DRB1∗0301, DRB3∗0101, DQA1∗0501, DQB1∗0201 has been reported by different research groups. This haplotype, which is more common in northern Europe, is also associated with a number of immune system dysfunctions in healthy subjects. Analyzing the data according to gender, some dysfunc- tions are observed in women but not in men, in agreement with the role of X-linked genes and/or estrogens in the development and progression of autoimmune diseases.…
