Evaluating diagnostic indicators of urogenital Schistosoma haematobium infection in young women: A cross sectional study in rural South Africa
2018
BackgroundUrine microscopy is the standard diagnostic method for urogenital S. haematobium infection. However, this may lead to under-diagnosis of urogenital schistosomiasis, as the disease may present itself with genital symptoms in the absence of ova in the urine. Currently there is no single reliable and affordable diagnostic method to diagnose the full spectrum of urogenital S. haematobium infection. In this study we explore the classic indicators in the diagnosis of urogenital S. haematobium infection, with focus on young women.MethodsIn a cross-sectional study of 1237 sexually active young women in rural South Africa, we assessed four diagnostic indicators of urogenital S. haematobium…
Mapping schistosoma haematobium for novel interventions against female genital schistosomiasis and associated HIV risk in kwazulu-natal, South Africa
2021
Abstract.Women with female genital schistosomiasis (FGS) have been found to have genital symptoms and a three-fold higher risk of HIV infection. Despite WHO recommendations, regular antischistosomal mass drug administration (MDA) has not yet been implemented in South Africa possibly because of the lack of updated epidemiological data. To provide data for future prevention efforts against FGS and HIV, this study explored Schistosoma haematobium prevalence in girls and young women and the effects of antischistosomal MDA, respectively. Urinary schistosomiasis and genital symptoms were investigated in 70 randomly selected secondary schools in three districts within KwaZulu-Natal and 18 primary …

Modelling and in vivo evaluation of Tendon forces and strain in dynamic rehabilitation exercises : a scoping review
2022
ObjectivesAlthough exercise is considered the preferred approach for tendinopathies, the actual load that acts on the tendon in loading programmes is usually unknown. The objective of this study was to review the techniques that have been applied in vivo to estimate the forces and strain that act on the human tendon in dynamic exercises used during rehabilitation.DesignScoping review.Data sourcesEmbase, PubMed, Web of Science and Google Scholar were searched from database inception to February 2021.Eligibility criteriaCross-sectional studies available in English or Spanish language were included if they focused on evaluating the forces or strain of human tendons in vivo during dynamic exerc…
The HITRAN2016 molecular spectroscopic database
2017
This paper describes the contents of the 2016 edition of the HITRAN molecular spectroscopic compilation. The new edition replaces the previous HITRAN edition of 2012 and its updates during the intervening years. The HITRAN molecular absorption compilation is composed of five major components: the traditional line-by-line spectroscopic parameters required for high-resolution radiative-transfer codes, infrared absorption cross-sections for molecules not yet amenable to representation in a line-by-line form, collision-induced absorption data, aerosol indices of refraction, and general tables such as partition sums that apply globally to the data. The new HITRAN is greatly extended in terms of …
[Analysis of patient safety culture in an out of hours primary care service.]
2020
Background: Aim of this study, part of a European collaborative research project, was to evaluate the "patient safety culture" (PSC) in a primary care out of hours service in order to provide the management with a baseline for improvement interventions. Methods: Cross sectional study with the administration of the Safety Attitude Questionnaire Ambulatory Version (SAQ-AV) administered to all the 56 doctors working out of hours in the ULSS 20 Verona Local Health Trust in April/May 2015. For each item of the questionnaire the average score, standard deviation, non-applicability, percentage of agreement, percentage of disagreement were calculated. Results: Doctors working out of hours appreciat…
Streptococcus mutans and Streptococcus sobrinus detection by Polymerase Chain Reaction and their relation to dental caries in 12 and 15 year-old scho…
2012
A cross-sectional study was carried out to determine the prevalence of Streptococcus mutans and Streptococcus sobrinus and the association of the two in a random sample (n=614) of the child population of the region of Valencia (Spain). Saliva samples were analyzed by the quantitative polymerase chain reaction (PCR) method to study the relation of these bacteria to caries prevalence and the DMFT index. The prevalence of S. mutans was 35.4% at age 12 and 22.9% at age 15, that of S. sobrinus 18.9% and 8.4% and that of the S. mutans-S. sobrinus association 18.2% and 6.8% respectively. At both 12 and 15 years of age, the caries prevalence rates were lower in the Streptococcus-free group of child…
Correlation between dental caries experience and mutans streptococci counts using saliva and plaque as microbial risk indicators in 3-8 year old chil…
2015
Objectives: Determination of the relative amounts of mutans streptococcus in both saliva and plaque and to study its correlation with dental caries in children. Study Design: The study comprised of 60 children aged 3-8 years divided into 2 groups (30 children in each): Group A- Children with more than 4 carious teeth and Group B- Children without caries. Saliva and plaque was collected from children of both the groups with the help of Dentocult SM strip test kit (Orion Diagnostic). Following incubation, mutans streptococcus scores (from 0 to 3) in each individual was evaluated and compared between both the groups. Results: On comparing the two groups, mean ± SD of saliva score and plaque sc…
Impacto del estatus de fragilidad sobre la salud y calidad de vida en personas mayores españolas
2020
Resumen: Objetivo: El objetivo de este trabajo se centra en evaluar la capacidad predictiva de una medida latente de fragilidad basada en los indicadores físicos propuestos para la Encuesta de Salud, Envejecimiento y Jubilación en Europa (SHARE) sobre la calidad de vida y la salud general percibida de una muestra representativa de personas mayores españolas. Diseño: Estudio descriptivo transversal. Emplazamiento: España. Participantes: La muestra estuvo compuesta por 4.498 personas mayores de 60 años que residían en la comunidad cuyos datos se obtuvieron de la sexta ola de la encuesta SHARE. Mediciones principales: Se empleó un modelo de ecuaciones estructurales para definir el factor de fr…
A Sample Selection Model for Unit and Item Nonresponse in Cross-Sectional Surveys
2007
We consider a general sample selection model where unit and item nonresponse simultaneously affect a regression relationship of interest, and both types of nonresponse are potentially correlated. We estimate both parametric and semiparametric specifications of the model. The parametric specification assumes that the errors in the latent regression equations follow a trivariate Gaussian distribution. The semiparametric specification avoids distributional assumptions about the underlying regression errors. In our empirical application, we estimate Engel curves for consumption expenditure using data from the first wave of SHARE (Survey on Health, Aging and Retirement in Europe).
