Conducting member checking within a qualitative case study on health-related behaviours in a large European city: Appraising interpretations and co-constructing findings.

Although member checking is a well-established strategy for appraising credibility, there is a lack of research reporting procedures and outcomes when using this strategy. In recent years, scholars have implemented new member checking strategies along with several epistemological stances. In this work, researchers conducted member checking in three neighbourhoods with different socioeconomic status in Madrid, Spain. Attendance at member checking meetings was lower than expected. Member checking meetings were conducted in public halls within each neighbourhood and lasted approximately 2 hours. During the first hour, researchers introduced the aim of the meetings and shared summarized research findings with attendees using a slideshow. During the second hour, attendees had the opportunity to comment on any aspect of the research. Researchers used grounded theory coding strategies and a constructivist approach informed the analysis of the transcribed member checking meetings. One core category emerged, and it was named 'Co-constructing findings and side effects of the interaction between researchers and participants in member checking'. Member checking attendees contributed to co-constructing findings by means of underscore and disagreement. It is possible that these meetings might have caused side effects such as unintended comparisons between neighbourhoods and negative health-related behaviours. Attendees wondered how the findings could improve their neighbourhoods. The meetings allowed interaction between participants and researchers and resulted in appraising and co-constructing qualitative research findings. More research is needed to advance knowledge about member checking.

Factors influencing dietary inequalities among adolescents in Madrid and Bilbao: a qualitative research project.

OBJECTIVE: To describe the design and methodology of a qualitative study to explore the main factors influencing dietary inequalities in adolescents in Madrid and Bilbao, Spain. METHOD: The study area included six neighborhoods (three in each city) of different socioeconomic status (SES): low, medium, and high. We sampled 12 secondary schools (six in each city: two per socioeconomic level). Our methodology comprised: 1) developing an ad hoc index to classify all neighborhoods according to their SES; 2) selecting the study area and sample; 3) conducting semi-structured interviews (n=36) and focus groups (n=24). Grounded theory and phenomenological analysis will be employed in data analysis. Initially, we found factors influencing in adolescents' diet such as gender, family environment, and SES. CONCLUSIONS: Systematizing the selection of neighborhoods and secondary schools, along with using appropriate methods, could serve as a foundation for future studies on health inequalities among adolescents.

[Pediatric renal abscesses: a diagnostic challenge]. / Absceso renal en Pediatría: un desafío diagnóstico.

Kidney abscess is an unusual entity in childhood with few studies about its clinical characteris tics. OBJECTIVE: To report the clinical presentation, diagnosis, and therapy used in a cohort of 20 children with kidney abscess. PATIENTS AND METHOD: retrospective study of cases of kidney abscess during a 10-year period at the Hospital Roberto del Río. The analysis of clinical, laboratory, and imaging characteristics were evaluated as well as the treatment usedfor this condition. RESULTS: 20 cases were reported among which 65% were women with a median age of 3.6 years. The most com mon clinical presentation was fever, vomit, and dysuria. Eighty percent of patients presented an increase of inflammatory parameters, 88% presented positive urine culture, and the most common organism identified was Escherichia Coli (77.8%). The diagnosis was mostly made through kidney ultrasound (75%) followed by an abdominal CT scan (35%). 93% of abscesses were unilateral. About 95% of the patients only required antibiotic treatment. Vesicoureteral reflux was diagno sed in 28% of the patients with no sphincter control, and only one of them presented high-grade reflux. In patients with sphincter control, bladder and bowel dysfunction (BBD) was diagnosed in 90% of the cases. Forty four percent of the patients with late DMSA renal scintigraphy presented renal scarring. CONCLUSIONS: In this series, pediatric kidney abscess appears with persistent fever despite the treatment, requiring prolonged antibiotic therapy and rarely surgical drains. We su ggest a study aimed at detecting modifiable factors, such as vesicoureteral reflux in patients with no sphincter control and BBD in patients with sphincter control, as well as identifying renal paren chymal sequels in all patients.

Can we improve our neighbourhoods to be more physically active? Residents' perceptions from a qualitative urban health inequalities study.

The objective of our study was to identify neighbourhood factors which prevent and encourage physical activity, according to the residents' perspective. We used qualitative methods, conducting 37 semi-structured interviews and 29 focus groups. The main results were that the type of physical activity that took place in every neighbourhood was different; access to sports facilities varied due to prices and safety issues; garbage and obstacles on sidewalks were a serious limitation to physical activity; economic instability had an impact on physical activity. These results might lead the perception and insights of residents to be considered in public health interventions.

Urban environment and dietary behaviours as perceived by residents living in socioeconomically diverse neighbourhoods: A qualitative study in a Mediterranean context.

Scholars have determined that low socioeconomic status (SES) is associated with unhealthy dietary behaviours and that local food environments shape food inequality. Less is known about how residents' perceptions of their food environment affect their dietary behaviours. We conducted 37 semistructured interviews and 29 focus groups in three socioeconomically distinct neighbourhoods in Madrid. We identified the following main categories related to social and physical food environments: (a) perceptions of healthy and unhealthy dietary behaviours, (b) children's relationships with food, (c) precariousness and (d) residential food retailer types. Older adults were perceived as healthier consumers, whereas younger people were identified as fast-food consumers. In the low- and middle-SES neighbourhoods, residents saw home-cooked legume-based stews as healthy food. In the high-SES neighbourhood, television cooking programs were highlighted as a positive influence. In the low- and middle-SES neighbourhoods, grandparents played an essential role in the transmission of healthy eating habits to their grandchildren. In the high-SES neighbourhood, children's diets at home were determined by school menus. In the low- and middle-SES neighbourhoods, participants talked about a black market where food could be purchased. Food retailers with low-quality foods were also highlighted. In all neighbourhoods, residents missed traditional food stores, and in the low- and middle-SES neighbourhoods, immigrant-run food stores were not well accepted. Our study presents the concepts shaping how neighbourhood SES differences affect dietary behaviours according to residents of a large Mediterranean city.

Qualitative examination of the perceived effects of a comprehensive smoke-free law according to neighborhood socioeconomic status in a large city.

Smoke-free legislations aim to protect non-smokers from second-hand smoke (SHS) exposure and improve population health outcomes. The aim of this study was to explore residents' perceptions to understand how people living in distinctive SES neighborhoods are differently affected by comprehensive smoke-free laws in a large city like Madrid, Spain. We conducted a qualitative project with 37 semi-structured interviews and 29 focus group discussions in three different SES neighborhoods within the city of Madrid. Constructivist grounded theory was used to analyze the transcripts. One core category arose in our analyses: Neighborhood inequalities in second-hand smoke (SHS) exposure in outdoor places. The enactment of the comprehensive smoke-free law resulted in unintended consequences that affected neighborhoods differently: relocation of smokers to outdoor setting, SHS exposure, noise disturbance and cigarette butt littering. Changes in the urban environment in the three neighborhoods resulted in the denormalization of smoking in outdoor public places, which was more clearly perceived in the high SES neighborhood. Changes in the built environment in outdoor areas of hospitality venues were reported to actually facilitate smoking. Comprehensive smoke-free laws resulted in denormalization of smoking, which might be effective in reducing SHS exposure. Extending smoking bans to outdoor areas like bus stops and hospitality venues is warranted and should include a public health inequalities perspective.

Predecessors of the giant 1960 Chile earthquake.

It is commonly thought that the longer the time since last earthquake, the larger the next earthquake's slip will be. But this logical predictor of earthquake size, unsuccessful for large earthquakes on a strike-slip fault, fails also with the giant 1960 Chile earthquake of magnitude 9.5 (ref. 3). Although the time since the preceding earthquake spanned 123 years (refs 4, 5), the estimated slip in 1960, which occurred on a fault between the Nazca and South American tectonic plates, equalled 250-350 years' worth of the plate motion. Thus the average interval between such giant earthquakes on this fault should span several centuries. Here we present evidence that such long intervals were indeed typical of the last two millennia. We use buried soils and sand layers as records of tectonic subsidence and tsunami inundation at an estuary midway along the 1960 rupture. In these records, the 1960 earthquake ended a recurrence interval that had begun almost four centuries before, with an earthquake documented by Spanish conquistadors in 1575. Two later earthquakes, in 1737 and 1837, produced little if any subsidence or tsunami at the estuary and they therefore probably left the fault partly loaded with accumulated plate motion that the 1960 earthquake then expended.

Cefalea en urgencias: utilidad de las neuroimágenes y la clasificación SIC / Migraine in the service of urgencies: utility of the neuro-image and the classification of the International Society of Migraines

El hematoma subdural puede ocasionar una imagen tomográfica de aspecto normal, lo que causa confusión en la práctica clínica. Como la clínica de esta entidad es variable y poco típica, discutimos un caso de cefalea, por hematoma subdural atendido en las urgencias; resaltando la importancia de usar la clasificación de la Sociedad Internacional de Cefaleas y de emplear las resonancia magnética en el diagnóstico del dolor de cabeza en la práctica diaria de la neurología y la neurocirugía
