Oral health service utilization by elderly beneficiaries of the Mexican Institute of Social Security in México city

<p>Abstract</p> <p>Background</p> <p>The aging population poses a challenge to Mexican health services. The aim of this study is to describe recent oral health services utilization and its association with socio-demographic characteristics and co-morbidity in Mexican Social Security beneficiaries 60 years and older.</p> <p>Methods</p> <p>A sample of 700 individuals aged 60+ years was randomly chosen from the databases of the Mexican Institute of Social Security (IMSS). These participants resided in the southwest of Mexico City and made up the final sample of a cohort study for identifying risk factors for root caries in elderly patients. Sociodemographic variables, presence of cognitive decline, depression, morbidity, medication consumption, and utilization of as well as reasons for seeking oral health services within the past 12 months were collected through a questionnaire. Clinical oral assessments were carried out to determine coronal and root caries experience.</p> <p>Results</p> <p>The sample consisted of 698 individuals aged 71.6 years on average, of whom 68.3% were women. 374 participants (53.6%) had made use of oral health services within the past 12 months. 81% of those who used oral health services sought private medical care, 12.8% sought social security services, and 6.2% public health services. 99.7% had experienced coronal caries and 44.0% root caries. Female sex (OR = 2.0), 6 years' schooling or less (OR = 1.4), and caries experience in more than 22 teeth (OR = 0.6) are factors associated with the utilization of these services.</p> <p>Conclusion</p> <p>About half the elderly beneficiaries of social security have made use of oral health services within the past 12 months, and many of them have to use private services. Being a woman, having little schooling, and low caries experience are factors associated with the use of these services.</p

How does the tobacco industry attempt to influence marketing regulations? A systematic review

BACKGROUND: The Framework Convention on Tobacco Control makes a number of recommendations aimed at restricting the marketing of tobacco products. Tobacco industry political activity has been identified as an obstacle to Parties' development and implementation of these provisions. This study systematically reviews the existing literature on tobacco industry efforts to influence marketing regulations and develops taxonomies of 1) industry strategies and tactics and 2) industry frames and arguments. METHODS: Searches were conducted between April-July 2011, and updated in March 2013. Articles were included if they made reference to tobacco industry efforts to influence marketing regulations; supported claims with verifiable evidence; were written in English; and concerned the period 1990-2013. 48 articles met the review criteria. Narrative synthesis was used to combine the evidence. RESULTS: 56% of articles focused on activity in North America, Europe or Australasia, the rest focusing on Asia (17%), South America, Africa or transnational activity. Six main political strategies and four main frames were identified. The tobacco industry frequently claims that the proposed policy will have negative unintended consequences, that there are legal barriers to regulation, and that the regulation is unnecessary because, for example, industry does not market to youth or adheres to a voluntary code. The industry primarily conveys these arguments through direct and indirect lobbying, the promotion of voluntary codes and alternative policies, and the formation of alliances with other industrial sectors. The majority of tactics and arguments were used in multiple jurisdictions. CONCLUSIONS: Tobacco industry political activity is far more diverse than suggested by existing taxonomies of corporate political activity. Tactics and arguments are repeated across jurisdictions, suggesting that the taxonomies of industry tactics and arguments developed in this paper are generalisable to multiple jurisdictions and can be used to predict industry activity

Reproductive biology of the pampas deer (Ozotoceros bezoarticus): a review

The pampas deer (Ozotoceros bezoarticus) is a South American grazing deer which is in extreme danger of extinction. Very little is known about the biology of the pampas deer. Moreover, most information has not been published in peer-reviewed scientific journals, and is only available in local publications, theses, etc. Therefore, our aim was to update and summarize the available information regarding the reproductive biology of the pampas deer. Moreover, in most sections, we have also included new, unpublished information. Detailed descriptions are provided of the anatomy of both the female and the male reproductive tract, puberty onset, the oestrous cycle and gestational length. Birthing and the early postpartum period are described, as are maternal behaviour and early fawn development, seasonal distribution of births, seasonal changes in male reproduction and antler cycle, reproductive behaviour, semen collection, and cryopreservation. Finally, an overview is given and future directions of research are proposed

Real-time near-body drug screening during autopsy I:use of the Randox biochip drugs of abuse DOA I and DOA II immunoassays

Screening for drugs of abuse is widely employed as part of forensic toxicology investigations. The nature of specimens collected at autopsy varies depending on local customs, the case circumstances, and the condition of the cadaver. It is generally accepted that wherever possible specimens of peripheral blood, liver, stomach contents, vitreous humor, and muscle can be useful for toxicological analysis. In some countries, legislation or religious custom may mitigate against the removal of postmortem tissue unless shown to be necessary. The availability of a sensitive and broad ranging near-body screening test may provide a useful tool to assist pathologists in making decisions regarding the retention of tissues for toxicology analysis. We describe the performance of the Randox drugs-of-abuse (DOA) arrays, DOA I and DOA II, for near-body screening using whole blood, urine, vitreous humor, liver, and psoas major muscle. Samples were obtained from 106 autopsies and screened for the presence of amphetamine, barbiturates, benzodiazepines, benzoylecgonine, buprenorphine, cannabinoids, fentanyl, ketamine, lysergic acid diethylamide, methadone, methamphetamine, methaqualone, methylenedioxymethylamphetamine (Ecstasy), opiates, oxycodone, phencyclidine, and propoxyphene in the mortuary whilst the postmortem was being performed. Blood from each case underwent confirmatory analysis using either gas chromatography-mass spectrometry, liquid chromatography with tandem mass spectrometry or diode array detection. Excellent agreement between the near-body screening tests on a variety of tissues and confirmatory analyses in blood was obtaine

Carbon Biogeochemistry of the Western Arctic: Primary Production, Carbon Export and the Controls on Ocean Acidification

The Arctic Ocean is an important sink for atmospheric carbon dioxide (CO2) with a recent estimate suggesting that the region accounts for as much as 15 % of the global uptake of CO2. The western Arctic Ocean, in particular is a strong ocean sink for CO2, especially in the Chukchi Sea during the open water season when rates of primary production can reach as high as 150 g C m−2. The Arctic marine carbon cycle, the exchange of CO2 between the ocean and atmosphere, and the fate of carbon fixed by marine phytoplankton appear particularly sensitive to environmental changes, including sea ice loss, warming temperatures, changes in the timing and location of primary production, changes in ocean circulation and freshwater inputs, and even the impacts of ocean acidification. In the near term, further sea ice loss and other environmental changes are expected to cause a limited net increase in primary production in Arctic surface waters. However, recent studies suggest that these enhanced rates of primary production could be short lived or not occur at all, as warming surface waters and increases in freshwater runoff and sea ice melt enhance stratification and limit mixing of nutrient-rich waters into the euphotic zone. Here, we provide a review of the current state of knowledge that exists about the rates of primary production in the western Arctic as well as the fate of organic carbon fixed by primary produces and role that these processes play in ocean acidification in the region
