A chemical status predictor. A methodology based on World-Wide sediment samples.
2015
As a consequence of the limited resources of underdeveloped countries and the limited interest of the developed ones, the assessment of the chemical quality of entire water bodies around the world is a utopia in the near future. The methodology described here may serve as a first approach for the fast identification of water bodies that do not meet the good chemical status demanded by the European Water Framework Directive (WFD). It also allows estimating the natural background (or reference values of concentration) of the areas under study using a simple criterion. The starting point is the calculation the World-Wide Natural Background Levels (WWNBLs) and World-Wide Threshold Values (WWTVs…
Multimorbidity and perceived stress: a population-based cross-sectional study among older adults across six low- and middle-income countries
2018
BACKGROUND:\ud Stress in chronic conditions or multimorbidity (≥2 chronic conditions) has been reported to affect clinical outcomes but there are no studies on the association between stress and chronic conditions/multimorbidity among older adults in low- and middle-income countries (LMICs). Thus, we investigated this association among adults aged ≥50 years across six LMICs.\ud \ud METHODS:\ud A cross-sectional analysis using data from the World Health Organization's Study on Global Ageing and Adult Health (China, Ghana, India, Mexico, Russia, South Africa) was conducted. A perceived stress score [range 0 (lowest stress) -100 (highest stress)] was computed based on two questions from the Pe…
Handgrip strength and depression among 34,129 adults aged 50 years and older in six low- and middle-income countries
2019
Introduction: Handgrip strength is a simple and inexpensive marker of health and mortality risk. It presents an ideal risk-stratifying method for use in low and middle-income countries (LMICs). There are, however, no population-based studies investigating the associations between handgrip strength and depression in LMICs. We aimed to assess these associations among community-dwelling middle-aged and older adults using nationally representative data from six LMICs. Method: Cross-sectional data on individuals aged ≥ 50 years from the World Health Organization's Study on Global Ageing and Adult Health were analyzed. Depression was based on the Composite International Diagnostic Interview. Weak…
Anxiety symptoms and mild cognitive impairment among community-dwelling older adults from low- and middle-income countries.
2021
Abstract Aim Anxiety may be a risk factor for mild cognitive impairment (MCI) but there is a scarcity of data on this association especially from low- and middle-income countries (LMICs). Thus, we investigated the association between anxiety and MCI among older adults residing in six LMICs (China, Ghana, India, Mexico, Russia, South Africa), and the mediational effect of sleep problems in this association. Methods Cross-sectional, community-based, nationally representative data from the WHO Study on global AGEing and adult health (SAGE) were analyzed. The definition of MCI was based on the National Institute on Ageing-Alzheimer's Association criteria. Multivariable logistic regression analy…
A New Species of Ligophorus (Monogenea: Dactylogyridae) from the gills of the Flathead Mullet Mugil cephalus (Teleostei: Mugilidae) from Mexico
2015
AbstractA new monogenean species, Ligophorus yucatanensis n. sp. from the gills of the flathead mullet Mugil cephalus from the Yucatan Peninsula, Mexico, is described. The new species can be differentiated from all other species of Ligophorus by the morphology of the accessory piece of the copulatory organ. Its main lobe is cylindrical, tunnelled expanded distally, slightly bowed with a characteristic membranous opening at level of medial bifurcation of the accessory piece, forming a thick-walled bulbshaped expansion that ends in a round labium. The secondary lobe is spatulate, straight, and shorter than the main lobe. In addition, the new species can be distinguished from other species by …
Knowledge of bisphosphonate-related osteonecrosis of the Jawsamong Mexican dentists
2017
Background Bisphosphonate-related osteonecrosis is an infrequent but potentially serious complication. Its treatment remains complex, and in some cases can be mutilating. Prevention, a correct diagnosis and opportune management are crucial. Material and Methods A cross-sectional study was made, interviewing 410 dentists with the aim of assessing their knowledge of the subject. Results Practically all of the dental professionals (99.7%) were found to lack sufficient knowledge of the prevention, diagnosis and management of bisphosphonate-related osteonecrosis. Conclusions Actions including increased diffusion in the professional media and inclusion of the subject in training programs are need…
INTIMATE PARTNER VIOLENCE: PERCEPTION AND REPRESENTATION OF VIOLENCE AGAINST WOMEN IN GUANAJUATO. A QUALITATIVE RESEARCH
Intimate partner violence and domestic violence refer to the violation of women’s rights, often provoked by socio-cultural norms based on a patriarchal matrix. In Mexican society, in particular, gender-based violence affects the physical and psychological well-being of Mexican women. Moreover, the social representations of women who suffer violence and the lack of an effective legislative framework often reproduce the legitimation of gender-based violence, enhancing negative stereotypes and prejudices. In this scenario, the voice of the women who suffer violence in intimate relationships is silenced. In particular, in public and academic debates the impact and consequences of violence again…
Wyzwania latynoamerykańskiej migracji jako zagrożenie dla bezpieczeństwa społecznego w zachodniej hemisferze
2017
W artykule autor przedstawia zróżnicowane spojrzenie na problem migracji: emigrację z krajów latynoamerykańskich i imigrancką perspektywę w Stanach Zjednoczonych. Problem ujmuje przede wszystkim jako wyzwanie i jednocześnie zagrożenie dla bezpieczeństwa społecznego, ze względu na współwystępujące problemy: nierówności społeczne, ubóstwo, wyzysk w miejscu pracy. Temat w dalszym ciągu jest aktualny, również ze względu na jego polityczne uwarunkowania, obecne w kampanii wyborczej w 2016 roku w Stanach Zjednoczonych.
Przemoc, narkotyki i bezpieczeństwo publiczne jako wyzwanie dla świata polityki w wieku XXI na przykładzie wybranych państw Ameryki Łacińskiej
2016
W artykule przeanalizowano kluczowe problemy bezpieczeństwa publicznego w wybranych państwach Ameryki Łacińskiej, który to region bywa postrzegany jako przestrzeń szczególnie narażona na wyzwania stojące przed elitami politycznymi próbującymi radzić sobie z wyzwaniami współczesnego świata, w optyce społecznej, gospodarczej i politycznej. Zwrócono szczególną uwagę na kwestie dotyczące intensyfikacji przemocy związanej z nierozwiązanym od kilku dekad problemem produkcji i eksportu narkotyków.
La atenuación de los marcadores de control de contacto en PRESEEA: un estudio comparativo entre España y México
2018
En el presente trabajo se estudia el valor atenuante de los marcadores conversacionales de control de contacto en el corpus de entrevistas PRESEEA en dos ciudades de España (Valencia y Madrid) y dos de México (Monterrey y México D. F.). A partir de la inclusión de las intervenciones tanto del entrevistador como del entrevistado, se observan una serie de tendencias que resultan comunes en estas dos variedades geográficas. Los resultados muestran que el entrevistado atenúa para proteger su imagen, mientras que el entrevistador utiliza esta estrategia pragmática como medio para conseguir información de su interlocutor. Esta recopilación de datos se puede dar a través de la petición directa de …
