Alcohol-dependent patients receiving specialised outpatient care: an overview of gender issues

OBJECTIVE: The objective of the present study, with focus on gender, was aimed at evaluating alcohol-dependent individual in terms of socio-demographic variables related to alcohol consumption and therapeutic interventions. METHODS: This is a retrospective cross-sectional study of 1,051 patients (833 men and 218 women), with diagnosis of alcohol dependence syndrome, according to ICD-10 criteria, who had sought treatment for the first time at a specialised health centre between 2000 and 2006. RESULTS: The results showed that women, compared to men, are more likely to be unemployed and without partner, in addition to having higher educational level, latter age of alcohol initiation, needing less outpatient alcohol detoxification program, consuming more fermented beverage, presenting less psychiatric comorbidities, and using less coadjutant medications during treatment. CONCLUSION: We can state that some peculiarities exist permeating both gender and alcohol consumption. A further focus on the characteristics of each population is needed to facilitate the adequate use of therapeutic interventions according to gender specificities.

A possible contribution to improving the therapeutic potentials of Babor's Typology of Alcohol Dependent Patients

ABSTRACT Objective The objective of this study was to replicate Babor's Typology and to explore clinical features related to personality traits that may underlie this classification, in order to improve its therapeutic possibilities. Methods Observational prospective study on a group of 273 male alcoholics. After a replication of Babor's variables, Cluster Analysis, Chi-Square – applied on clinical variables related to a Lappda Tipology – and Kappa tests were performed. Results The study identified two distinct clusters that held similar features to those described for the Type A/Type B classification. Besides presenting a lower socio-economic situation, Cluster 2 patients were associated with higher vulnerability and severe clinical features and also differed from Cluster 1 in their response to treatment. These replicated clusters retained connections and also differences in relation to the variables derived from the Lappda Typology. Conclusion Considering that each of the two replicated clusters seem to be associated to different personality traits – according to their correlations to the affective, cognitive and behavioral dimensions brought forward by the Lappda Typology – it is acceptable that this study may contribute to the development of more comprehensive and effective therapeutic strategies specifically tailored to target more specific personality traits of these subgroups of alcoholic patients.

Extraction and characterization of polysaccharides from non-traditional Brazilian Amazon sources

[Excerpt] Cupuassu (Theobroma grandiflorum), tucumã (Astrocaryum aculeatum), peach palm (Bactris gasipaes) and abricó (American Mammea L.) are exotic fruits found in the Brazilian Amazon rainforest. All of them are well known by the native populations, and for centuries the pulps have been used in the production of juices, deserts, jams, syrups, and alcoholic beverages, among others. Additionally, the fruit seeds have been used as animal feed, fertilizers or to plant new seedlings, but a great part of these seeds are usually discarded. (...)

Laboratory assessment of the hypertensive individual. Value of the main guidelines for high blood pressure

OBJECTIVE: To determine if abnormal laboratory findings are more common in individuals with hypertension and in those with other risk factors, such as obesity, smoking and alcohol ingestion. METHODS: A study was carried out in the general outpatient clinics of a university hospital (145 individuals without previous diagnosis of hypertension) and the following variables were assessed: high blood pressure (as defined by the VI Joint National Committee on Prevention, Detection and Treatment of High Blood Pressure - VI JNC), obesity [calculated using body mass index (BMI)], tobacco use, and alcoholic ingestion. The laboratory examinations consisted of the following tests: hemogram, glycemia, uric acid, potassium, total/HDL-fraction cholesterol, triglycerides, calcium and creatinine. RESULTS: High blood pressure was not associated with a higher number of abnormal laboratory tests. Hypertensive individuals with a BMI > or = 25kg/m² or normotensive obese individuals, however, had a higher frequency of diabetes (12X), hypertriglyceridemia (3X), and hypercholesterolemia (2X), as compared with hypertensive individuals with BMI <25kg/m² and preobese/normal weight normotensive individuals. CONCLUSION: High blood pressure is not associated with a higher frequency of abnormal laboratory tests. The association of high blood pressure and obesity, however, increases the detection of diabetes and dyslipidemias.

Reversibility of ventricular dysfunction: clinical experience in a medical office

OBJECTIVE - To describe clinical observations of marked improvement in ventricular dysfunction in a medical office environment under circumstances differing from those in study protocols and multicenter studies performed in hospital or with outpatient cohorts. METHODS - Eleven cardiac failure patients with marked ventricular dysfunction receiving treatment at a doctors office between 1994 and 1999 were studied. Their ages ranged from 20 and 66 years (mean 39.42±14.05 years); 7 patients were men, 4 were women. Cardiopathic etiologies were arterial hypertension in 5 patients, peripartum cardiomyopathy in 2, nondefined myocarditis in 2, and alcoholic cardiomyopathy in 4. Initial echocardiograms revealed left ventricular dilatation (average diastolic diameter, 69.45±8.15mm), reduced left ventricular ejection fraction (0.38±0.08) and left atrial dilatation (43.36±5.16mm). The therapeutic approach followed consisted of patient orientation, elimination of etiological or causal factors of cardiac failure, and prescription of digitalis, diuretics, and angiotensinconverting enzyme inhibitors. RESULTS - Following treatment, left ventricular ejection fraction changed to 0.63±0.09; left ventricular diameters changed to 57.18±8.13mm, and left atrium diameters changed to 37.27±8.05mm. Maximum improvement was noted after 16.9±8.63 (6 to 36) months. CONCLUSION - Patients with serious cardiac failure and ventricular dysfunction caused by hypertension, alcoholism, or myocarditis can experience marked improvement in ventricular dysfunction after undergoing appropriate therapy within the venue of the doctor's office.

The Yanomami indians in the INTERSALT study

OBJECTIVE: To study the distribution and inter-relationship among constitutional and biochemical variables with blood pressure (BP) in an population of Yanomami indians. To compare these findings with those of other populations. METHODS: The Yanomami indians were part of the INTERSALT, a study comprising 10,079 males and females, aged from 20 to 59 years, belonging to 52 populations in 32 countries in Africa, the Americas, Asia, and Europe. Each of the 52 centers was required to accrue 200 individuals, 25 participants in each age group. The variables analyzed were as follows: age, sex, arterial BP, urinary sodium and potassium excretion (24-hour urine), body mass index, and alcohol ingestion. RESULTS: The findings in the Yanomami population were as follows: a very low urinary sodium excretion (0.9 mmol/24h); mean systolic and diastolic BP levels of 95.4 mmHg and 61.4 mmHg, respectively; no cases of hypertension or obesity; and they have no knowledge of alcoholic beverages. Their BP levels do not elevate with age. The urinary sodium excretion relates positively and the urinary potassium excretion relates negatively to systolic BP. This correlation was maintained even when controlled for age and body mass index. CONCLUSION: A positive relation between salt intake and blood pressure was detected in the analysis of a set of diverse populations participating in the INTERSALT Study, including populations such as the Yanomami Indians. The qualitative observation of their lifestyle provided additional information.

Envelhecimento das aguardentes

1 - Colour, by itself, does not constitute a solid ground for judging of the age of a brandy because the more or less pronounced colour it acquires through aging can also be obtained by the addition of oack essence to newly distilled brandy. 2 - Urder the same conditions, colour intensity of a brandy wiU depend upon the nature of the wood and the condition of the storage. 3 - In accordance with the experimental results obtained by the present writers it rests no doubt that fermentation facility ferment resistence, produce and quality of the brendy all are factors depending upon the variety of the sugar cane. In addition, the authors presume that the variety of sugar cane has also influence upon the alteration of composition of the brandy submitted to aging. 4 - All aging phenomena of the brandy are accompanied by volume decreasing, what happens in a slow and continuous manner depending upon storage and environment conditions 5 - During brandy aging the alcoholic degree is greatly af- fected by evaporation, increasing or decreasing in accordance to the hygrometric state of the air and the teriperature in the place where the tuns are stored. 6 - The specific weight of the brandy is inversely proportio- nal to its alcoholic degree, but directly proportional to the extracts since the latter indicates the amount of dissolved residues. 7 - Brandy which shows high specific weight together with high alcoholic degree cannot be considered as aged. It may, however, be takens for brandy artificially coloved in order to conceal its actual age. 8 - The amount of extracts increases with aging, since it is the result of the solvent action of the brandy upon the soluble extractive substances of the wood. Notwithstanding that the extract, considered alone, has no value in determining the age of a brandy, since nothing easier is ohan to nake it change artificially. 9 -During aging the brandy get acidity in physiological as well as in physical way, but never by the action of microorganisms. 10 - The estturs produced during aging by the action of acids upon alcohols are the mean factors of the savour (bouquet) of a brandy and therefore every thing shall be done tor fhr estherification of a preserved brandy being not limited. 11 - Aeration increases esther formation, reduces the aging- time and turn better the taste qualities of the brandy. 12 - Due to the great proportion of high alcohols ordinarily found in the brandy, their analytical discrimination will be greatly important. 13 - The high alcohols are not responsable for the disastrous consequences of the alcoholism, but the high percentage of uthyl alcohol present in the brandy. 14 - The aldehydes appear always in high rate in the brazilian brandys in consequence of some intermediary products of the oxydation of the alcohols being left in the brandys during aging. 15 - The age has little or no influence on the quantity of phurphurol present in a brandy whose amount varies greatly the manner in which the wines to be distilled are treated. Wines centrifugalized or filtered before distillation always give rise to brandys poorer in phurphurol as compared with those distilled without these treatments. 16 - Though greatly variable, brandys of good qualities generally show a high residues coefficient, never under 200 mmg 17 - Lusson - Rocques oxydation coefficient cannot be indis- criminately applied to any brandy class, being, on the contrary, specifically destined to cognacs.

Estudos sobrea determinação da vitamina B¹ (aneurina, tiamina) na herva mate

The infusion used as a beverage and known as tea of Paraguay or male (Ilex paraguarensis, St. Hil.) contains vitamin B (aneurin). 2) Aneurin determinations were made on the infusion commonly used (water extract) and on the complete water and alcohol extracts. The presence of aneurin was detected in both extracts. For quantitative study aneurin was adsorbed from the extracts (pH 3.8-4.0) by means of fuller's earth and kaolin. 3) Animal tests with pigeons and mice (curative, preventive and maintenance of body weight) give positive but inconstant results. No exact quantitative values could be obtained with the animal test. 4) Schopfer-Jung test based on the development of the mould « Phycomyces blakesleeanus, Bgf » showed constant results. Regular growth curves were obtained with the adsorbate of kaolin and fuller's earth. 5) The thiochrome fluorescence test introduced by Jansen was applied to the detection of aneurin in the adsorbate and good results were found which check closely with those encountered by the Schopfer-Jung test. 6) The determinations of aneurin by means of the Phycomyces and thiochrome tests gave values varying from 60 to 280 y per 100 gr. 7) Green leaves are more rich in aneurin than dry ones.

Excreção urinária de 17-Cetoesteroides neutros no cavalo normal e no cavalo castrado

Total urinary neutral 17-steroids were determined in normal and in castrated horses. One liter of a 15-26 hours urine collection was hydrolysed by refluxing with 10% HC1 (v/v) for ten minutes and extracted with peroxyde-free ethyl ether. The extract was purified by washing with saturated NaHCO³ and KOH solutions. One half of the crude neutral fraction was fractionated with Girard's "T" reagent . The Zimmermann reaction was performed both in the ketonic and in the crude neutral extracts, using alcoholic 2.5N KOH and a 60 minutes period for the colour development in the dark. Optical density measuments were made in a grating Coleman Universal Spectrophotometer at 420 mµ and 520mµ; for the crude neutral fraction a colour correction equation was applied. The aliquot fraction used for colorimety was adjusted for keeping optical density measurements within the range 0.2 to 0.7. Androsterone (mp. 184-184.5°C) with an absorption maximum at 290.5 mµ (Beckman Model DU Spectrophotometer) was used as a reference standard. Table I, ilustrates the results obtained. At the 0.05 probability level there is a significant difference among castrated and normal group means (Fischer's "t" test.) when were used the data obtained from the ketonic fractions; in spite of the use of a colour correction applied for inespecific chromogens, the same results could not be obtained with the crude neutral fractions, Since Girard's reagent fractionation is generaly accepted as the best method for correcting the inespecific chromogen interference in the determination of the 17-ketosteroids by the Zimmermann reaction, we emphasize the value of the results obtained with the ketonic fractions. From these results it appears, as occurs in others mammals, that castrated horses show a lower level of urinary 17-ketosteroids excretion than the normal horses. The significance of the horse testis contribution for the neutral urinary steroid metabolites is discussed. Since horse urine has a low androgenic activity, the fractionation of the neutral 17-ketosteroids must be studied more accurately.

Prévalence de la dénutrition chez 143 adultes en bilan prétransplantation hépatique. Experience lausannoise de 1997 a 2005 [Prevalence of undernutrition in 143 patients before liver transplantation. The Lausanne experience between 1997 and 2005]

The prevalence of undernutrition was prospectively studied in 143 patients before liver transplantation between 1997 and 2005. Nutritional assessment is a particularly tricky problem in cirrhosis and mid-arm muscle circumference is considered as the best reliable anthropometric tool. In this prospective study, prevalence rate is very high (61%) and undernutrition is more frequent in alcoholic cirrhotic patients. In conclusion, these patients should benefit from an early dietician intervention before liver transplantation.

Prévention des alcoolisations aiguës a l'adolescence: quel rôle pour le médecin de famille [Prevention of binge drinking in adolescents: do family doctors have a role to play?].

Binge drinking has nearly become the norm for young people and is thus worrying. Although alcohol use in males attracts more media attention, females are also frequently affected. A variety of preventive measures can be proposed: at the individual level by parents, peers and family doctors; at the school and community level, particularly to postpone age of first use and first episode of drunkenness; at the structural level through a policy restricting access to alcohol for young people and increasing its price. Family doctors can play an important role in identifying at risk users and individualising preventive messages to which these young people are exposed in other contexts.

Consum de productes de les màquines de vending i hàbits alimentaris entre els estudiants de la Universitat de Vic

Introducció: Entre els comportaments alimentaris que poden contribuir a una ingesta dietètica inadequada hi ha el consum d’aliments de conveniència, aliments que es caracteritzen per ser d’elevat contingut calòric, riquesa en greixos saturats i sucres. Les màquines de vending són un dels principals exemples de disponibilitat d’aliments de conveniència. Objectius: Avaluar entre els estudiants de la Universitat de Vic (UVic) els hàbits de consum de productes de les màquines de vending i estudiar les característiques generals dels seus hàbits alimentaris. Materials i mètodes: Enquesta realitzada a 253 estudiants de la UVic durant el curs 07/08. Resultats: Un 72.7% dels enquestats consumeixen productes de les Màquines Expenedores d’Aliments i Begudes (MEAB), fonamentalment com a complement dels àpats i un 63.8% dels enquestats refereix que els agradaria rebre informació nutricional sobre els productes ofertats. Els hàbits alimentaris dels estudiants són bastant adequats ja que un 81.4% realitza almenys 4 àpats diaris. La qualitat de l’esmorzar és bona en el 12.3% dels casos i entre aquells que prenen algun aliment a mig matí la qualitat total de l’esmorzar millora (55.7% bona qualitat). Segons el Kidmed un 39.9% realitzen una dieta mediterrània i s’observen diferències segons la qualitat total de l’esmorzar (p&0.001). Conclusions: El consum de productes de les MEAB en l’entorn universitari és molt important, per la qual cosa la millora del perfil nutricional i la implantació d’estratègies informatives sobre els productes, permetrà que els consumidors estiguin més informats i puguin fer una elecció alimentària més saludable. Els hàbits alimentaris de la població d’estudi reflexen que la qualitat de la dieta dels universitaris és bastant bona, tot i que diferents factors podrien millorar-se. Paraules clau: màquines expenedores d’aliments i begudes (MEAB), hàbits alimentaris, universitaris.
