A baseline survey for capturing the hearing ability and hearing disability of students at the universities of Oldenburg, Groningen and the University of applied sciences Utrecht

Mittels einer Anfang 2011 durchgeführten Online-Erhebung wurden Studierende an den Universitäten Oldenburg, Groningen und der Hochschule Utrecht in Bezug auf die Hörsituation an ihrer Bildungseinrichtung befragt. Die Erhebung verfolgte das Ziel, den Anteil der Studierenden mit einer Hörbeeinträchtigung an den genannten Standorten differenziert zu erfassen. Eine statistische Analyse der Daten ergab, dass an allen drei Einrichtungen mehr als 25 Prozent der Studierenden von einer Beeinträchtigung im Hören betroffen waren, wobei eine Geräuschempfindlichkeit die am häufigsten genannte Hörbeeinträchtigung darstellte. (DIPF/Orig.)Data of hearing in university context based situations were collected in an online survey by the universities of Oldenburg and Groningen and the University of Applied Sciences Utrecht. The study examined the subjective hearing ability of all students including the numbers of students with hearing disabilities. The results show that 25 percent of the participants mention at least one kind of hearing-disability. Hypersensitivity to sound is named first as of the main hearing-disabilities. (DIPF/Orig.

The sound of study:Student experiences of listening in the university soundscape

The students from three universities (Groningen, Oldenburg and the University of Applied Sciences in Utrecht) were surveyed on the experience of hearing and listening in their study. Included in the online survey were established questionnaires on hearing loss, tinnitus, hyperacusis, a subscale on psychosocial strain resulting from impaired hearing and a questionnaire about students’ perceptions of listening ease in study environments. Results from the 10,466 students who completed the survey (13% response rate) are highlighted, with particular attention to listening ease and measures proposed by students for improving it. A consequence from our findings is that more effective classroom practice may be won if study soundscapes can be improved, while universities might exercise greater inclusive responsibility for study as high quality sensory experience for the benefit of all students

Methodological approaches for conducting follow-up research with clinical trial participants: a scoping review and expert interviews

Evidence-based establishment and implementation of best principles, laws and ordinances that regulate clinical research depend on the consultation and involvement of trial participants. Yet, guidance on methodological approaches to obtain trial participants' perspectives is currently missing. This scoping review therefore aimed at identifying, describing and evaluating research approaches to obtain trial participants' feedback on their views and experiences.; We searched the electronic databases Medline and PsycInfo via Ovid and the Web of Science Core Collection. Clinical trials were included that involved adult participants that were conducted in selected high-income countries and that were published in peer-reviewed journals between 1985 and 2018. In addition, 29 expert interviews were conducted between March and May 2019.; Out of 5994 identified records, 23 articles were included in this review. Twelve studies used a qualitative approach, 10 were quantitative and one study used a mixed-method design. More than 75% of all work was conducted in the USA and the UK. The scoping review and the expert interviews highlighted that recruitment of participants was generally done through direct contact by principal investigators and/or study nurses or through searches in de-identified patient databases. Authors used surveys, interviews or focus group discussions. The tools used were either based on existing validated ones or developed and verified de novo with the support of experts and/or patient representatives.; To our knowledge, this is the first methodological literature review of approaches to researching experiences of clinical trial participants where findings were triangulated with expert interviews. Covering a range of indications, trial phases and study settings, it demonstrates that clinical trial participant perspectives and experience is heavily under-researched. This casts doubt on the overall robustness of available insight into trial participants' views and experiences. Our results demonstrate that the methodology for studying participant opinion, perception and experience should be adapted to the measure of interest and conform to the study population. Using valid patient experience data is the basis to evaluate existing legal and regulatory human subject research frameworks for their appropriateness from a patient perspective. Such an evaluation will be critical to empower research participants

How does district health management emerge within a complex health system? Insights for capacity strengthening in Ghana

Introduction:; District health managers (DHMs) play a pivotal role in the operation of district health systems in low-and middle income countries, including Ghana. Their capacity is determined by their competencies, but also by the organization and system in which they are embedded. The objective of this paper is to explore how district health management emerges from contextual, organizational, and individual factors in order to demonstrate that capacity strengthening efforts at district level need to transcend individual competencies to take on more systemic approaches.; Methods:; Semi-structured interviews (; n; = 21) were conducted to gain insight into aspects that affect district health management in the Eastern Region of Ghana. Interviews were conducted with DHMs (; n; = 15) from six different districts, as well as with their superiors at the regional level (; n; = 4) and peers from non-governmental organizations (; n; = 2). A thematic analysis was conducted by using an analytical approach based on systems theory.; Results:; Contextual aspects, such as priorities among elected officials, poor infrastructure and working conditions, centralized decision-making, delayed disbursement of funds and staff shortages, affect organizational processes and the way DHMs carry out their role. Enabling organizational aspects that provide DHMs with direction and a clear perception of their role, include positive team dynamics, good relations with supervisors, job descriptions, appraisals, information systems, policies and guidelines. Meanwhile, hierarchical organizational structures, agendas driven by vertical programs and limited opportunities for professional development provide DHMs with limited authority to make decisions and dampens their motivation. The DHMs ability to carry out their role effectively depends on their perception of their role and the effort they expend, in addition to their competencies. In regards to competencies, a need for more general management and leadership skills were called for by DHMs as well as by their superiors and peers.; Conclusion:; Systemic approaches are called for in order to strengthen district health management capacity. This study can provide national policy-makers, donors and researchers with a deeper understanding of factors that should be taken into consideration when developing, planning, implementing, and assessing capacity-building strategies targeted at strengthening district health management

Nutritional and health status of children 15 months after integrated school garden, nutrition, and water, sanitation and hygiene interventions: a cluster-randomised controlled trial in Nepal

It has been suggested that specific interventions delivered through the education sector in low- and middle-income countries might improve children's health and wellbeing. This cluster-randomised controlled trial aimed to evaluate the effects of a school garden programme and complementary nutrition, and water, sanitation and hygiene (WASH) interventions on children's health and nutritional status in two districts of Nepal.; The trial included 682 children aged 8-17 years from 12 schools. The schools were randomly allocated to one of three interventions: (a) school garden programme (SG; 4 schools, n = 172 children); (b) school garden programme with complementary WASH, health and nutrition interventions (SG+; 4 schools, n = 197 children); and (c) no specific intervention (control; 4 schools, n = 313 children). The same field and laboratory procedures were employed at the baseline (March 2015) and end-line (June 2016) surveys. Questionnaires were administered to evaluate WASH conditions at schools and households. Water quality was assessed using a Delagua kit. Dietary intake was determined using food frequency and 24-h recall questionnaire. Haemoglobin levels were measured using HemoCue digital device and used as a proxy for anaemia. Stool samples were subjected to a suite of copro-microscopic diagnostic methods for detection of intestinal protozoa and helminths. The changes in key indicators between the baseline and end-line surveys were analysed by mixed logistic and linear regression models.; Stunting was slightly lowered in SG+ (19.9 to 18.3%; p = 0.92) and in the control (19.7 to 18.9%). Anaemia slightly decreased in SG+ (33.0 to 32.0%; p < 0.01) and markedly increased in the control (22.7 to 41.3%; p < 0.01), a minor decline was found in the control (43.9 to 42.4%). Handwashing with soap before eating strongly increased in SG+ (from 74.1 to 96.9%; p = 0.01, compared to control where only a slight increase was observed from 78.0 to 84.0%). A similar observation was made for handwashing after defecation (increase from 77.2 to 99.0% in SG+ versus 78.0 to 91.9% in control, p = 0.15).; An integrated intervention consisting of school garden, WASH, nutrition and health components (SG+) increased children's fruit and vegetable consumption, decreased intestinal parasitic infections and improved hygiene behaviours.; ISRCTN17968589 (date assigned: 17 July 2015)

Prevalence and risk factors of undernutrition among schoolchildren in the Plateau Central and Centre-Ouest regions of Burkina Faso

Multiple factors determine children's nutritional status, including energy and nutrient intake, recurrent infectious diseases, access (or lack thereof) to clean water and improved sanitation, and hygiene practices, among others. The "Vegetables go to School: improving nutrition through agricultural diversification" (VgtS) project implements an integrated school garden programme in five countries, including Burkina Faso. The aim of this study was to determine the prevalence of undernutrition and its risk factors among schoolchildren in Burkina Faso before the start of the project.; In February 2015, a cross-sectional survey was carried out among 455 randomly selected children, aged 8-14 years, in eight schools in the Plateau Central and Centre-Ouest regions of Burkina Faso. Nutritional status was determined by anthropometric assessment. Helminth and intestinal protozoa infections were assessed using the Kato-Katz and a formalin-ether concentration method. A urine filtration technique was used to identify Schistosoma haematobium eggs. Prevalence of anaemia was determined by measuring haemoglobin levels in finger-prick blood samples. Questionnaires were administered to children to determine their knowledge of nutrition and health and their related attitudes and practices (KAP). Questionnaires were also administered to the children's caregivers to identify basic household socio-demographic and economic characteristics, and water, sanitation and hygiene (WASH) conditions. To determine the factors associated with schoolchildren's nutritional status, mixed logistic regression models were used. Differences and associations were considered statistically significant if P-values were below 0.05.; Complete datasets were available for 385 children. The prevalence of undernutrition, stunting and thinness were 35.1%, 29.4% and 11.2%, respectively. The multivariable analysis revealed that undernutrition was associated with older age (i.e. 12-14 years compared to &lt;12 years; adjusted odds ratio (aOR) = 3.45, 95% confidence interval (CI) 2.12-5.62, P &lt; 0.001), multiple pathogenic parasitic infections (aOR = 1.87, 95% CI 1.02-3.43, P = 0.044) and with moderate and severe anaemia in children (aOR = 2.52, 95% CI 1.25-5.08, P = 0.010).; We found high prevalence of undernutrition among the children surveyed in the two study regions of Burkina Faso. We further observed that undernutrition, anaemia and parasitic infections were strongly associated. In view of these findings, concerted efforts are needed to address undernutrition and associated risk factors among school-aged children. As part of the VgtS project, WASH, health education and nutritional interventions will be implemented with the goal to improve children's health.; ISRCTN17968589 (date assigned: 17 July 2015)

Prevalence of intestinal parasitic infections and associated risk factors among schoolchildren in the Plateau Central and Centre-Ouest regions of Burkina Faso

BACKGROUND: Unsafe drinking water, unimproved sanitation and lack of hygiene pose health risks, particularly to children in low- and middle-income countries. This study aimed to assess the prevalence and risk factors of intestinal parasitic infections in school-aged children in two regions of Burkina Faso. METHODS: A cross-sectional survey was carried out in February 2015 with 385 children aged 8-14 years from eight randomly selected schools in the Plateau Central and Centre-Ouest regions of Burkina Faso. Stool samples were subjected to the Kato-Katz and a formalin-ether concentration method for the diagnosis of helminths and intestinal protozoa infections. Urine samples were examined with a urine filtration technique for Schistosoma haematobium eggs. Water samples from community sources (n = 37), children's households (n = 95) and children's drinking water cups (n = 113) were analysed for contamination with coliform bacteria and faecal streptococci. Data on individual and family-level risk factors were obtained using a questionnaire. Mixed logistic regression models were employed to determine factors associated with intestinal parasitic infections in schoolchildren. RESULTS: Intestinal parasitic infections were highly prevalent; 84.7 % of the children harboured intestinal protozoa, while helminth infections were diagnosed in 10.7 % of the children. We found significantly lower odds of pathogenic intestinal protozoa infection (Entamoeba histolytica/E. dispar and Giardia intestinalis) among children from the Plateau Central, compared to the Centre-Ouest region (P < 0.001). Children from households with "freely roaming domestic animals" (P = 0.008), particularly dogs (P = 0.016) showed higher odds of G. intestinalis, and children reporting exposure to freshwater sources through domestic chores had higher odds of S. haematobium infection compared to children without this water contact activity (P = 0.035). Water quality, household drinking water source and storage did not emerge as significant risk factors for intestinal parasitic infections in children. CONCLUSIONS: Intestinal protozoa but not helminths were highly prevalent among schoolchildren in randomly selected schools in two regions of Burkina Faso. Our findings call for specific public health measures tailored to school-aged children and rural communities in this part of Burkina Faso. It will be interesting to assess the effect of water, sanitation and hygiene interventions on the transmission of intestinal parasitic infections

Challenges and best practices for digital unstructured data enrichment in health research: A systematic narrative review

Digital data play an increasingly important role in advancing health research and care. However, most digital data in healthcare are in an unstructured and often not readily accessible format for research. Unstructured data are often found in a format that lacks standardization and needs significant preprocessing and feature extraction efforts. This poses challenges when combining such data with other data sources to enhance the existing knowledge base, which we refer to as digital unstructured data enrichment. Overcoming these methodological challenges requires significant resources and may limit the ability to fully leverage their potential for advancing health research and, ultimately, prevention, and patient care delivery. While prevalent challenges associated with unstructured data use in health research are widely reported across literature, a comprehensive interdisciplinary summary of such challenges and possible solutions to facilitate their use in combination with structured data sources is missing. In this study, we report findings from a systematic narrative review on the seven most prevalent challenge areas connected with the digital unstructured data enrichment in the fields of cardiology, neurology and mental health, along with possible solutions to address these challenges. Based on these findings, we developed a checklist that follows the standard data flow in health research studies. This checklist aims to provide initial systematic guidance to inform early planning and feasibility assessments for health research studies aiming combining unstructured data with existing data sources. Overall, the generality of reported unstructured data enrichment methods in the studies included in this review call for more systematic reporting of such methods to achieve greater reproducibility in future studies

Intestinal parasite infections and associated risk factors among schoolchildren in Dolakha and Ramechhap districts, Nepal: a cross-sectional study

Infections with soil-transmitted helminths and pathogenic intestinal protozoa pose a considerable public health burden, particularly in low- and middle-income countries, including Nepal. We assessed the extent of intestinal parasite infections among schoolchildren in two districts of Nepal and determined underlying risk factors.; A cross-sectional survey was conducted between March and May 2015 in the districts of Dolakha and Ramechhap, Nepal. A total of 708 children, aged 8-16 years from 16 purposively selected schools, were enrolled. Each child provided a single stool sample that was subjected to a suite of copro-microscopic diagnoses for intestinal protozoa and helminths. Drinking water samples from different sources at schools (n = 29), community places (n = 43) and households (n = 562) were analysed for contamination with thermotolerant coliforms (TTC). A questionnaire was administered to determine individual- and household-level risk factors of intestinal parasite infections. Self-reported symptoms were assessed and a clinical examination was undertaken by a physician. Haemoglobin was measured and used as a proxy for anaemia. Mixed logistic regression models were applied to investigate associations.; The overall prevalence of intestinal parasite infections was 39.7%. Trichuris trichiura (30.9%), Giardia intestinalis (30.5%) and hookworm (30.2%) were the predominant intestinal parasite infections. Children from households lacking soap for handwashing were at higher odds of intestinal parasite infections than children who had soap [adjusted odds ratio (aOR) 1.81; 95% confidence interval (CI): 1.13-2.89; P = 0.01]. Children from households without freely roaming domestic animals showed lower odds of G. intestinalis compared to children from households with freely roaming animals (aOR 0.52; 95% CI: 0.33-0.83; P = 0.01). One out of three (31.0%) children suffered from fever and 22.4% had watery diarrhoea within a two-week recall period. Anaemia was diagnosed in 23.6% of the children. Water contamination with TTC showed no clear association with intestinal parasite infection.; Intestinal parasites are common among schoolchildren in the two surveyed districts of Nepal. An important risk factor was lack of soap for handwashing. Our findings call for efforts to control intestinal parasite infection and emphasis should be placed on improvements in water, sanitation and hygiene interventions.; ISRCTN17968589 (date assigned: 17 July 2015)
