Consumo e ingesta de alcohol en españoles mayores de 16 años y su relación con la actividad físico-deportiva, la familia y el conumo de tabaco

[ES] El objetivo fue conocer la relación entre el consumo de alcohol, diferentes variables socio-demográficas, el consumo de tabaco y la práctica de ejercicio físico en adultos de tres provincias del sur de España. Una muestra representativa de 3.373 personas de Almería, Granada y Murcia, con edades comprendidas entre los 16 y 96 años, las cuales cumplimentaron el cuestionario “Hábitos físico-deportivos y estilos de vida”, participaron en el presente estudio. Se encontró que el consumo de alcohol estaba muy influido por los distintos miembros de la familia y la pareja. La práctica físico-deportiva en adultos no fue un factor de protección para el consumo de alcohol, ya que fueron las personas que nunca habían realizado ejercicio físico y quienes habían abandonado la práctica físico-deportiva las que menos probabilidad tenían de consumir alcohol de manera habitual o esporádica. No obstante, fueron las personas sedentarias y las que habían abandonado la práctica regular de ejercicio físico las que tenían una mayor probabilidad (hasta el doble de riesgo) de tener un consumo de riesgo y alto riesgo en cuanto a la cantidad de alcohol ingerido. Además, los datos indicaron que el consumo de tabaco sí que era un factor significativamente predisponente para el consumo de alcohol.

Mangia, bevi, ama. Cibo e rituali alimentari del matrimonio nell'Occidente altomedievale

La ricerca pone al centro dell’indagine lo studio dell’importanza del cibo nelle cerimonie nuziali dell’Europa occidentale nei secoli V-XI. Il corpus di fonti utilizzate comprende testi di genere diverso: cronache, annali, agiografie, testi legislativi, a cui si è aggiunta un’approfondita analisi delle antiche saghe islandesi. Dopo un'introduzione dedicata in particolare alla questione della pubblicità della celebrazione, la ricerca si muove verso lo studio del matrimonio come “processo” sulla base della ritualità alimentare: i brindisi e i banchetti con cui si sigla l’accordo di fidanzamento e i ripetuti convivi allestiti per celebrare le nozze. Si pone attenzione anche ad alcuni aspetti trasversali, come lo studio del caso della “letteratura del fidanzamento bevuto”, ossia una tradizione di testi letterari in cui il fidanzamento tra i protagonisti viene sempre ratificato con un brindisi; a questo si aggiunge un’analisi di stampo antropologico della "cultura dell’eccesso", tipica dei rituali alimentari nuziali nel Medioevo, in contrasto con la contemporanea "cultura del risparmio". L'analisi si concentra anche sulle reiterate proibizioni al clero, da parte della Chiesa, di partecipare a banchetti e feste nuziali, tratto comune di tutta l’epoca altomedievale. Infine, la parte conclusiva della ricerca è incentrata sulla ricezione altomedievale di due figure bibliche che pongono al centro della narrazione un banchetto nuziale: la parabola delle nozze e il banchetto di Cana. L’insistente presenza di questi due brani nelle parole dei commentatori biblici mostra la straordinaria efficacia del “linguaggio alimentare”, ossia di un codice linguistico basato sul cibo (e su contesti quali l’agricoltura, la pesca, ecc.) come strumento di comunicazione sociale di massa con una valenza antropologica essenzialmente universale.

The Relationship of UK University Students with Alcohol: Binge Drinking and its Risks

Il presente studio è stato effettuato per comprendere le abitudini degli studenti universitari britannici in termini di consumo di alcol e i rischi legati a due fenomeni frequenti nel Regno Unito: il binge drinking (consumo eccessivo di alcol in un breve lasso di tempo, spesso per raggiungere velocemente lo stato di ebbrezza) e, in misura minore, il drink spiking (contaminazione di bevande con droghe o alcol). Attraverso un’analisi di studi accademici, sondaggi e articoli della stampa britannica, verrà presentato nella prima parte il ruolo dell’alcol nel Regno Unito, verranno fornite varie definizioni di binge drinking ed evidenziate le variazioni di significato del termine nel tempo. Saranno, poi, presentati i livelli di assunzione di riferimento di alcol emessi dall’NHS, il sistema sanitario nazionale del Regno Unito, seguiti da un’analisi sull’uso dell’alcol nel Regno Unito. Per quanto riguarda gli studenti universitari, verranno analizzati i motivi che li spingono al consumo di alcol, il binge drinking e le NekNomination (giochi alcolici online), l’uso dei pre-drinks (ritrovi serali tra amici per bere alcol prima di uscire) e le modalità in cui college e università aiutano gli studenti per evitare loro di incorrere in rischi legati all’alcol. In particolare, verranno analizzati drink spiking, violenze sessuali e fisiche, rischi per la salute e morte accidentale, e verranno presentate alcune strategie applicate per evitarli. La seconda parte verterà sull’analisi e discussione dei risultati di un sondaggio realizzato a Durham (Regno Unito) nel febbraio 2015 attraverso interviste a studenti universitari britannici e portieri di college e proprietari e membri dello staff di pub e bar locali con domande basate sulle loro esperienze, opinioni ed eventuali testimonianze riguardo il consumo di alcol, i fenomeni e i rischi sopra menzionati. Lo studio ha portato a vari risultati che hanno permessi di confermare e ampliare conoscenze pregresse sui temi trattati.

Mobile phone technologies and advanced data analysis towards the enhancement of diabetes self-management

Advances in the area of mobile and wireless communication for healthcare (m-Health) along with the improvements in information science allow the design and development of new patient-centric models for the provision of personalised healthcare services, increase of patient independence and improvement of patient's self-control and self-management capabilities. This paper comprises a brief overview of the m-Health applications towards the self-management of individuals with diabetes mellitus and the enhancement of their quality of life. Furthermore, the design and development of a mobile phone application for Type 1 Diabetes Mellitus (T1DM) self-management is presented. The technical evaluation of the application, which permits the management of blood glucose measurements, blood pressure measurements, insulin dosage, food/drink intake and physical activity, has shown that the use of the mobile phone technologies along with data analysis methods might improve the self-management of T1DM.

Analysis of the erosive effect of different dietary substances and medications

Excessive consumption of acidic drinks and foods contributes to tooth erosion. The aims of the present in vitro study were twofold: (1) to assess the erosive potential of different dietary substances and medications; (2) to determine the chemical properties with an impact on the erosive potential. We selected sixty agents: soft drinks, an energy drink, sports drinks, alcoholic drinks, juice, fruit, mineral water, yogurt, tea, coffee, salad dressing and medications. The erosive potential of the tested agents was quantified as the changes in surface hardness (ΔSH) of enamel specimens within the first 2 min (ΔSH2-0 = SH2 min - SHbaseline) and the second 2 min exposure (ΔSH4-2 = SH4 min - SH2 min). To characterise these agents, various chemical properties, e.g. pH, concentrations of Ca, Pi and F, titratable acidity to pH 7·0 and buffering capacity at the original pH value (β), as well as degree of saturation (pK - pI) with respect to hydroxyapatite (HAP) and fluorapatite (FAP), were determined. Erosive challenge caused a statistically significant reduction in SH for all agents except for coffee, some medications and alcoholic drinks, and non-flavoured mineral waters, teas and yogurts (P < 0·01). By multiple linear regression analysis, 52 % of the variation in ΔSH after 2 min and 61 % after 4 min immersion were explained by pH, β and concentrations of F and Ca (P < 0·05). pH was the variable with the highest impact in multiple regression and bivariate correlation analyses. Furthermore, a high bivariate correlation was also obtained between (pK - pI)HAP, (pK - pI)FAP and ΔSH.

Investigation into the Specificity of Angiotensin II-induced Behavioral Desensitization

Angiotensin II (AngII) plays a key role in maintaining body fluid homeostasis. The physiological and behavioral effects of central AngII include increased blood pressure and fluid intake. In vitro experiments demonstrate that repeated exposure to AngII reduces the efficacy of subsequent AngII, and behavioral studies indicate that prior icv AngII administration reduces the dipsogenic response to AngII administered later. Specifically, rats given a treatment regimen of three icv injections of a large dose of AngII, each separated by 20 min, drink less water in response to a test injection of AngII than do vehicle-treated controls given the same test injection. The present studies were designed to test three potential explanations for the reduced dipsogenic potency of AngII after repeated administration. To this end, we tested for motor impairment caused by repeated injections of AngII, for a possible role of visceral distress or illness, and for differences in the pressor response to the final test injection of AngII.We found that repeated injections of AngII neither affected drinking stimulated by carbachol nor did they produce a conditioned flavor avoidance. Furthermore, we found no evidence that differences in the pressor response to the final test injection of AngII accounted for the difference in intake. In light of these findings, we are able to reject these three explanations for the observed behavioral desensitization, and, we suggest instead that the mechanism for this phenomenon may be at the level of the receptor.

Electrolyte Depletion in White-nose Syndrome Bats

The emerging wildlife disease white-nose syndrome is causing widespread mortality in hibernating North American bats. White-nose syndrome occurs when the fungus Geomyces destructans infects the living skin of bats during hibernation, but links between infection and mortality are underexplored. We analyzed blood from hibernating bats and compared blood electrolyte levels to wing damage caused by the fungus. Sodium and chloride tended to decrease as wing damage increased in severity. Depletion of these electrolytes suggests that infected bats may become hypotonically dehydrated during winter. Although bats regularly arouse from hibernation to drink during winter, water available in hibernacula may not contain sufficient electrolytes to offset winter losses caused by disease. Damage to bat wings from G. destructans may cause life-threatening electrolyte imbalances.

Depressive symptoms as a predictor of alcohol relapse after residential treatment programs for alcohol use disorder

Alcohol use disorder (AUD) and depressive disorders often co-occur. Findings on the effects of major depressive disorder (MDD) or depressive symptoms on posttreatment alcohol relapse are controversial. The study's aim is to examine the association of MDD and depressive symptoms with treatment outcomes after residential AUD programs. In a naturalistic-prospective, multisite study with 12 residential AUD treatment programs in the German-speaking part of Switzerland, 64 patients with AUD with MDD, 283 patients with AUD with clinically significant depressive symptoms at admission, and 81 patients with AUD with such problems at discharge were compared with patients with AUD only on alcohol use, depressive symptoms, and treatment service utilization. MDD was provisionally identified at admission and definitively defined at discharge. Whereas patients with MDD did not differ from patients with AUD only at 1-year follow-up, patients with AUD with clinically significant depressive symptoms had significantly shorter time-to-first-drink and a lower abstinence rate. These patients also had elevated AUD indices and treatment service utilization for psychiatric disorders. Our results suggest that clinically significant depressive symptoms are a substantial risk factor for relapse so that it may be important to treat them during and after residential AUD treatment programs.

Full Cups, Full Coffers: Tax Strategies and Consumer Culture in the Early Modern German Cities

During the sixteenth and seventeenth centuries, the excise taxes (Ungeld) paid by town residents on the consumption of beer, wine, mead and brandy represented the single most important source of civic revenue for many German cities. In a crisis, these taxes could spike to 70-80% of civic income. This paper examines civic budgets and 'behind-the-scenes' deliberations in a sample of towns in southern Germany in order to illuminate how decisions affecting consumer taxes were made. Even during the sobriety movements of the Reformation and post-Reformation period, tax income from drinkers remained attractive to city leaders because the bulk of the excise tax burden could easily be shifted away from privileged members of society and placed on the population at large. At the same time, governments had to maintain a careful balance between what they needed in order to govern and what the consumer market could bear, for high taxes on drinks were also targeted in many popular revolts. This led to nimble politicking by those responsible for tax decisions. Drink taxes were introduced, raised, lowered and otherwise manipulated based not only on shifting fashions and tastes but also on the degree of economic stress faced by the community. Where civic rulers were successful in striking the right balance, the rewards were considerable. The income from drink sales was a major factor in how the cities of the Empire survived the wars and other crises of the early modern period without going into so much debt that they lost their independence.

Drinking, Family Relations and Authority in Early Modern Germany

The ideal of orderly family life in early modern Germany did not exclude drinking. In fact, drinks shared at the family table were closely tied to early modern notions of the marital bond and were also a necessary component of normal work relations. Drinking became a problem only when it threatened the stability of the household. The amount of alcohol involved in such cases might be as little as one drink if the circumstances were unsuitable. On the other hand, drinking that would by our standards be viewed as excessive or chronic could be considered acceptable . Even during and immediately after the period of Reformation, when polemical and prescriptive literature addressing the household was dominated by the problem of sin, drunkenness was rarely treated as a spiritual issues. The primary concern of both authorities and populace was not to protect the health or the rights of individuals but to protect the sanctity of the household and the stability of the community.

Palatability of crushed ß-blockers, converting enzyme inhibitors and thiazides

WHAT IS KNOWN AND OBJECTIVES: A problem that often affects antihypertensive drugs is the lack of formulations appropriate for childhood. Parents, therefore, crush tablets and administer the antihypertensive drug mixed with solid food or a palatable drink. Because palatability is a major modulator of adherence to prescribed medication, the palatability of crushed ß-blockers, converting enzyme inhibitors and thiazides was assessed among adult volunteers.

Hypertonic NaCl infusions affect milk composition in goats

The capability of goats to maintain milk production during water deprivation is remarkable and not yet fully understood. The aim of the present study was to investigate whether intravenous infusions of hypertonic NaCl cause release of both vasopressin and oxytocin and whether the peptides, in combination with the hyperosmolality, affect milk flow and milk composition. Six Swedish domestic landrace goats in their first to third lactation were milked every 30 min during experiments. Hypertonic NaCl (HNaCl) or isotonic NaCl (IsoNaCl) were infused for 90 min. Goats were not allowed to drink during infusions. Plasma vasopressin concentration increased during HNaCl infusions, and did not change in response to IsoNaCl infusions. Plasma oxytocin concentration did not change during either infusion. Milk flow was maintained during the infusions. Milk fat concentration decreased in the three samples taken before onset of the infusions, but then increased gradually during HNaCl infusions, while it continued to fall during the IsoNaCl infusions. Milk osmolality followed the rise in plasma osmolality during the HNaCl infusions and did not change in IsoNaCl experiments. Milk lactose concentration increased throughout both series of experiments, the concentration being higher during HNaCl infusions. Milk protein concentration did not change during HNaCl infusions, but fell in the IsoNaCl experiments. It is concluded that the hyperosmolality in combination with elevated plasma vasopressin levels did not disturb the secretory activity of the mammary cells, but rather facilitated emptying of the alveolar milk. Such a mechanism may help to explain the sustained milk production in water deprived goats.

Extrinsic causes of erosion. Diet. Chemical factors

pH value, calcium, and phosphate and to a lesser extent fluoride content of a drink or foodstuff are important factors explaining erosive attack. They determine the degree of saturation with respect to tooth minerals, which is the driving force for dissolution. Solutions oversaturated with respect to dental hard tissue will not dissolve it. Addition of calcium (and phosphate) salts to erosive drinks showed protection of surface softening. Today, several Ca-enriched soft drinks are on the market or products with naturally high content in Ca and P are available (such as yoghurt), which do not soften the dental hard tissue. The greater the buffering capacity of the drink or food, the longer it will take for the saliva to neutralize the acid. The buffer capacity of a solution has a distinct effect on the erosive attack when the solution remains adjacent to the tooth surface and is not replaced by saliva. A higher buffer capacity of a drink or foodstuff will enhance the processes of dissolution because more ions from the tooth mineral are needed to render the acid inactive for further demineralization. Further, the amount of drink in the mouth in relation to the amount of saliva present will modify the process of dissolution. There is no clear-cut critical pH for erosion as there is for caries. Even at a low pH, it is possible that other factors are strong enough to prevent erosion.

Risk assessment and preventive measures

A prerequisite for preventive measures is to diagnose erosive tooth wear and to evaluate the different etiological factors in order to identify persons at risk. No diagnostic device is available for the assessment of erosive defects. Thus, they can only be detected clinically. Consequently, erosion not diagnosed in the early stage may render timely preventive measures difficult. In order to assess the risk factors, patient should record their dietary intake for a distinct period of time. Then a dentist can determine the erosive potential of the diet. Particularly, patients with more than four dietary acid intakes have a higher risk for erosion when other risk factors (such as holding the drink in the mouth) are present. Regurgitation of gastric acids (reflux, vomiting, alcohol abuse, etc.) is a further important risk factor for the development of erosion which has to be taken into account. Based on these analyses, an individually tailored preventive program may be suggested to the patients. It may comprise dietary advice, optimization of fluoride regimes, stimulation of salivary flow rate, use of buffering medicaments and particular motivation for nondestructive toothbrushing habits with a low abrasive toothpaste. The frequent use of fluoride gel and fluoride solution in addition to fluoride toothpaste offers the opportunity to reduce somewhat abrasion of tooth substance. It is also advisable to avoid abrasive tooth cleaning and whitening products, since they may remove the pellicle and may render teeth more susceptible to erosion. Since erosion, attrition and abrasion often occur simultaneously all causative components must be taken into consideration when planning preventive strategies.
