Adaptation and validation into Portuguese language of the HIV Antibody Testing Attitude Scale

Objective. To culturally adapt and validate a version in European Portuguese language of the HIV Antibody Testing Attitude Scale. Methods. Study conducting a methodological investigation for the adaptation and validation of an attitude measurement instrument. The instrument translation and back-translation were performed. Then, a pre-test was conducted. The study used a sample of 317 subjects from the academic community - students, professors and other professionals - who were contacted in the campus. Ethical principles were observed. Results. Three analyses were conducted using the method of principal component analysis (PCA) with five, four and three factors. A three-factor solution was achieved, which presents 50.82% variance. In the analysis of inter-item correlation, values between -0.018 and 0.749 were observed. Internal consistency shows Cronbach’s alpha coefficients of 0.860 overall and between 0.865 and 0.659 in the three factors. Conclusion. The instrument version shows psychometric properties that allow its use in Portuguese-speaking countries.

COMMUNITY KNOWLEDGE, ATTITUDE AND PRACTICES (KAP) ON FLUOROSIS AND ITS MITIGATION IN ENDEMIC AREAS OF ETHIOPIA

Optimum fluoride intake plays an essential role in the prevention of dental caries while fluoride consumption above recommended level interferes with the normal formation of tooth enamel and bones and may increase risk of dental and skeletal fluorosis. The knowledge and practices of endemic communities on etiology of fluorosis will help in its mitigation and prevention. The objective of this study was to investigate the knowledge, attitude and practices of endemic community on fluoride contamination, fluorosis and prevention practices in order to devise coordinated and targeted prevention mechanisms. Focus group discussions (FGD) and key-informant interview were conducted in three dietary areas to collect knowledge, attitude and practices (KAP) of the endemic community in July 2013.The results indicated that health consequences of fluoride contaminated water are fairly understood. None of the discussants mentioned the word “fluoride”. The knowledge and perception of the community on fluoride ingestion is poor. Health extension workers (HEWs) did not teach about fluoride and related health consequences. Dental fluorosis was reported to start at early ages and not commonly perceived as a major problem. However, adolescents worried and felt that they might be singled out when going to other areas. Older people have a skeletal fluorosis, which interferes with their day to day activities. In severely affected people, the teeth were weak and fragile and thus create difficulty in chewing hard foods like unfermented dry flat bread, sugar cane and toasted grains. People prefer rain water rather than water from borehole because of the inconvenient taste of the latter. The endemic communities have no sufficient knowledge and skills on potential sources of fluoride intake, the debilitating effect of high fluoride ingestion, and preventive and mitigatory measures to reduce fluoride intake. The effect of fluoride contamination and mitigatory methods should get sufficient attention by the community, health workers and concerned governmental bodies. The trend of harvesting and using rain water should be encouraged as it reduces fluoride intake. Future studies should focus on information communication on possible fluoride risks, intervention and evaluation studies on defluoridation, rain water harvesting and mitigatory techniques.

Healthcare providers’ knowledge, attitude and behaviour towards breast cancer diagnosis and treatment in Malaysia – a mini systematic review

Breast cancer is the most common cancer among women in Malaysia. Therefore, it is important for the public to be educated on breast cancer and to know the steps that need to be taken to detect it early. Healthcare providers are in a unique position to provide public health education due to their good knowledge of health issues and their roles in healthcare. A systematic review of studies conducted from 2008 till 2015 was undertaken to analyze the knowledge, attitudes and behavior of Malaysian healthcare providers regarding breast cancer, in an attempt to obtain an overall picture of how wellequipped the healthcare providers are to provide optimal breast cancer education, and to ascertain their perceptions and actual involvement in such education. The systematic review was conducted via a primary search of various databases and journal websites, and a secondary search of references cited in eligible studies. Criteria for eligibility include studies conducted in Malaysia and published from the year 2008 to 2015, and written in English language. A total of fifteen articles were identified and reviewed but only two studies were eligible for this review. The findings suggest that future and current Malaysian healthcare providers have moderate knowledge of breast cancer, showed a positive disposition towards involvement in breast cancer education, but displayed poor involvement.

The Relationship of Culturally Responsive Instruction and the Reading Comprehension and Attitude of Struggling Urban Adolescent Readers

Culturally responsive instruction refers to the identification of relevant cultural aspects of students’ lives and infusion of these into the curriculum. This instructional approach assumes that a culturally appropriate curriculum can potentially motivate, engage, and lead students to higher rates of achievement. This quasi-experimental study (N=44) investigated the relationship of culturally responsive instruction and the reading comprehension and attitude of struggling urban adolescent readers. The study incorporated the use of culturally responsive instruction using culturally relevant literature (CRL), the Bluford Series Novels, as authentic texts of instruction. Participants were seventh grade reading students at a Title I middle school in South Florida. After a baseline period, two different classes were taught for 8 weeks using different methods. One class formed the experimental group (n=22) and the other class formed the comparison group (n=22). The CRI curriculum for the experimental group embraced the socio-cultural perspective through the use of small discussion groups in which students read and constructed meaning with peers through interaction with the Bluford Series Novels; gave written responses to multiple strategies according to SCRAP – Summarize, Connect, Reflect, Ask Questions, Predict; responded to literal and inferential questions, while at the same time validating their responses through evidence from the text. The Read XL (basal reader) curriculum of the comparison group utilized a traditional form of instruction which incorporated the reading of passages followed by responses to comprehension questions, and teacher-led whole group discussion. The main sources of data were collected from the Gates-MacGinitie Reading Tests, the Florida Assessments for Instruction in Reading (FAIR), and the Rhody Secondary Reading Attitude Assessment. Statistical analyses were performed using Repeated Measures ANOVAs. Findings from the study revealed that the experimental participants’ reading attitudes and FAIR comprehension scores increased when compared to the comparison group. Overall, the results from the study revealed that culturally responsive instruction can potentially foster reading comprehension and a more positive attitude towards reading. However, a replication of this study in other settings with a larger, more randomized sample size and a greater ethnic variation is needed in order to make full generalizations.

Adaptation and validation of HIV Antibody Testing Attitude Scale in Portuguese

Introduction; The awareness of HIV positiveness is important for health of the individual and of the comunity. The identicatio of HIV antibodies is possible both using conventional lab tests and quick result tests. In the bibliography it was made clear that there are no instruments in Portuguese to assert the reactions to the HIV quick tests and it was therefore considered it would be useful to adapt and validate a scale in Portuguese, since the language is the official language of 7 different countries and spoken by more than 250 milion people, Objectives: the purpose is to validate a version in European Portuguese of the HIV Antibody Testing Attitude Scale. Methods: the study refers to methodological research for the adaptation and validation of an instrument of attitude measurement. A translation and back-translation was prepared and a trial test was then carried out. A total of 317 students, lectures and co-workers of a Portuguese University was interviewes. Ethical principles were taken into consideration. the pool was obtained in the seven components of the University campus. Results: 3 trials of factorial testing of the main components of 5, 4 and 3 factors. It ended up a solution of 3 factors that explains 50.82% of the variability. In the analysis of the inter-items correlation values of between 0.018 and 0.749 were observed. The internal consistency reveals an alpha Cronbach coefficient of 0.860 as a whole, and in between 0,865 and 0.659 in the 3 factors. Conclusions: this version of the instrument shows that the psychometric properties allow its use in the Portuguese speaking countries.

Nonlinear Approaches to Attitude Control Using Magnetic and Mechanical Actuation

This thesis argues the attitude control problem of nanosatellites, which has been a challenging issue over the years for the scientific community and still constitutes an active area of research. The interest is increasing as more than 70% of future satellite launches are nanosatellites. Therefore, new challenges appear with the miniaturisation of the subsystems and improvements must be reached. In this framework, the aim of this thesis is to develop novel control approaches for three-axis stabilisation of nanosatellites equipped with magnetorquers and reaction wheels, to improve the performance of the existent control strategies and demonstrate the stability of the system. In particular, this thesis is focused on the development of non-linear control techniques to stabilise full-actuated nanosatellites, and in the case of underactuation, in which the number of control variables is less than the degrees of freedom of the system. The main contributions are, for the first control strategy proposed, to demonstrate global asymptotic stability derived from control laws that stabilise the system in a target frame, a fixed direction of the orbit frame. Simulation results show good performance, also in presence of disturbances, and a theoretical selection of the magnetic control gain is given. The second control approach presents instead, a novel stable control methodology for three-axis stabilisation in underactuated conditions. The control scheme consists of the dynamical implementation of an attitude manoeuvre planning by means of a switching control logic. A detailed numerical analysis of the control law gains and the effect on the convergence time, total integrated and maximum torque is presented demonstrating the good performance and robustness also in the presence of disturbances.

Methodologies for attitude determination from MEMS sensors in vehicles

The focus of the thesis is the application of different attitude’s determination algorithms on data evaluated with MEMS sensor using a board provided by University of Bologna. MEMS sensors are a very cheap options to obtain acceleration, and angular velocity. The use of magnetometers based on Hall effect can provide further data. The disadvantage is that they have a lot of noise and drift which can affects the results. The different algorithms that have been used are: pitch and roll from accelerometer, yaw from magnetometer, attitude from gyroscope, TRIAD, QUEST, Magdwick, Mahony, Extended Kalman filter, Kalman GPS aided INS. In this work the algorithms have been rewritten to fit perfectly with the data provided from the MEMS sensor. The data collected by the board are acceleration on the three axis, angular velocity on the three axis, magnetic fields on the three axis, and latitude, longitude, and altitude from the GPS. Several tests and comparisons have been carried out installing the electric board on different vehicles operating in the air and on ground. The conclusion that can be drawn from this study is that the Magdwich filter is the best trade-off between computational capabilities required and results obtained. If attitude angles are obtained from accelerometers, gyroscopes, and magnetometer, inconsistent data are obtained for cases where high vibrations levels are noticed. On the other hand, Kalman filter based algorithms requires a high computational burden. TRIAD and QUEST algorithms doesn’t perform as well as filters.

La rieducazione posturale globale (RPG) e efficace in soggetti con low back pain cronico aspecifico? Una revisione sistematica della letteratura

Background: La lombalgia (o Low Back Pain -LBP) è una condizione multifattoriale e complessa che rappresenta una delle principali cause di disabilità al mondo. Si definisce “cronica” quando persiste per più di 12 settimane e “aspecifica” quando non risultano identificabili i meccanismi eziologici alla base della patologia. La Rieducazione Posturale Globale (RPG) è una metodica fisioterapica il cui scopo è quello di allungare i muscoli accorciati, migliorare la contrazione dei muscoli antagonisti e controllare la respirazione, migliorando la morfologia corporea. Obiettivo: Valutare, nei soggetti con LBP cronico aspecifico, l’efficacia della RPG rispetto a dolore, disabilità, articolarità, forza muscolare, qualità della vita, prevenzione delle recidive. Metodi: Sono state consultate le seguenti banche dati biomediche: PubMed, Cochrane Library, Scopus, SportDiscus e PEDro, nel periodo tra il 1° maggio e il 30 settembre 2022. Sono stati inclusi studi randomizzati controllati (RCTs) e studi sperimentali non randomizzati (NRSI) in lingua italiana, inglese o francese, senza restrizione inerente all’anno di pubblicazione. Un solo autore indipendente ha estratto i dati. Per valutare il rischio di bias degli studi inclusi sono stati impiegati il Cochrane Rob2 tool per gli RCT e il ROBINS-I per i NRSI. Risultati: 7 studi (5 RCT e 2 NRSI) hanno soddisfatto i criteri di eleggibilità e sono stati inclusi. Si è riscontrata una bassa qualità metodologica: cinque studi con alto rischio di bias e due studi con moderato rischio di bias. In tutti i trials la metodica RPG si è mostrata efficace nel ridurre dolore e disabilità, soprattutto a breve termine; tuttavia non ci sono sufficienti prove per affermarne la superiorità rispetto ad altre terapie. Conclusioni: La RPG è in grado di ridurre il dolore e la disabilità in soggetti con LBP cronico aspecifico nel breve termine. Studi futuri con maggiore validità interna sono necessari per conferire maggior certezza alle evidenze.

Il ruolo del controllo posturale per il movimento selettivo degli arti superiori attraverso la facilitazione con trunk constraint nel paziente neurologico: case report

Background Recentemente la letteratura scientifica ha dimostrato come un corretto controllo posturale faciliti i movimenti dell’arto superiore. Ci sono evidenze secondo cui, applicando al paziente dei contenimenti sul tronco, si ha un miglioramento della funzionalità dell’arto superiore. Obiettivi L’obiettivo principale della tesi era quello di verificare come il sostegno del tronco con l’utilizzo di una stabile struttura assiale, attraverso un supporto esterno definito “trunk constraint”, incrementi il controllo posturale, per facilitare i movimenti frazionati degli arti superiori in persone con esiti di patologie neurologiche. Materiali e metodi Il caso clinico riguarda un uomo di 60 anni con esiti di emiparesi sinistra da ictus ischemico destro. E’ stato eseguito un protocollo di dieci sessioni di trattamento, di un’ora ciascuna, in cui veniva applicata la facilitazione attraverso trunk constraint in diversi setting riabilitativi. I dati sono stati raccolti tramite le scale: Trunk Control Test, Trunk Impairment Scale e Fugl-Meyer Assessment. Inoltre, è stata eseguita l’analisi osservazionale, attraverso videoripresa, di un gesto funzionale dell’arto superiore. Risultati I dati rilevati dimostrano degli effetti positivi rispetto alle ipotesi di partenza. Infatti sono stati riscontrati miglioramenti negli item delle scale somministrate e nella valutazione qualitativa dell’arto superiore. In particolare, si è evidenziato un miglioramento nel controllo del tronco nella scala Trunk Control Test e nella Trunk Impairment Scale e della funzione dell’arto superiore alla scala Fugl-Meyer Assessment. L’analisi osservazionale dei video dimostra un miglioramento del timing di attivazione durante la fase di reaching. Conclusioni I risultati ottenuti supportano il fatto che un incremento dell’attività antigravitaria del tronco, anche attraverso supporti esterni come la trunk constraint, possono facilitare un miglioramento funzionale dell’arto superiore.

Analisi del controllo posturale in soggetti con amputazione unilaterale agli arti inferiori mediante posturografia dinamica: una revisione sistematica dalla letteratura.

Una delle limitazioni funzionali più comunemente citate dai soggetti con amputazione agli arti inferiori è il deficit nel controllo dell’equilibrio. La perdita, più o meno parziale, di un arto è accompagnata da mancanze e succisivi adattamenti del sistema di controllo posturale. Considerando l’aumento dell’età della popolazione generale e la crescente incidenza delle cause di amputazioni su di essa, vi è un’inequivocabile necessità di indagare come il controllo posturale cambi in questi individui. A tal riguardo, è stata condotta una revisione sistematica dei metodi proposti in letteratura riguardanti l’analisi del controllo posturale in soggetti con amputazione unilaterale agli arti inferiori, mediante la posturografia dinamica. Partendo dall’articolo di riferimento: “Balance control in lower extremity amputees during quiet standing: A systematic review” (Ku et al., 2013), a dicembre 2022 è stata evidenziata ed estesa la ricerca, fino all’anno corrente, degli articoli riguardanti il medesimo argomento, ma esclusivamente in ambito dinamico. Dalla ricerca, condotta su PubMed e Scopus, sono stati selezionati 8 articoli scientifici, nei quali, attraverso l’utilizzo di dispositivi di equilibrio, vengono analizzati i meccanismi alla base del controllo posturale nelle persone con amputazione agli arti inferiori. Dai risultati si è potuto dimostrare che gli amputati unilaterali degli arti inferiori fanno molto affidamento su input visivi, vestibolari e segnali somatosensoriali dalla loro gamba intatta per compensare le informazioni somatosensoriali mancanti dell'arto amputato. Quando uno di questi viene compromesso, mostrano uno scarso controllo posturale rispetto agli individui normodotati.
