The oral cancer epidemic in central and eastern Europe.

To monitor recent trends in oral and pharyngeal cancer mortality in 38 European countries, we analyzed data provided by the World Health Organization over the period 1975-2004. Joinpoint analysis was used to identify significant changes in trends. In the European Union (EU), male mortality rates rose by 2.1% per year between 1975 and 1984, by 1.0% between 1984 and 1993, and declined by 1.3% between 1993 and 2004, to reach an overall age-standardized rate of 6.1/100,000 in 2000-2004. Mortality rates were much lower in women, and the rate in the EU rose by 0.9% per year up to 2000, and levelled off to 1.1/100,000 in 2000-2004. In France and Italy - which had the highest rates in the past - male rates have steadily declined during the last two decades (annual percent change, APC=-4.8% in 1998-2004 in France, and -2.6% in 1986-2003 in Italy). Persisting rises were, however, observed in several central and eastern European countries, with exceedingly high rates in Hungary (21.1/100,000; APC=6.9% in 1975-1993 and 1.4% in 1993-2004) and Slovakia (16.9/100,000; APC=0.14% in 1992-2004). In middle aged (35 to 64) men, oral and pharyngeal cancer mortality rates in Hungary (55.2/100,000) and Slovakia (40.8/100,000) were comparable to lung cancer rates in several major European countries. The highest rates for women were in Hungary (3.3/100,000; APC=4.7% in 1975-2004) and Denmark (1.6/100,000; APC=1.3% in 1975-2001). Oral and pharyngeal cancer mortality essentially reflects the different patterns in tobacco smoking and alcohol drinking, including drinking patterns and type of alcohol in central Europe.

Derivaciones en los centros de salud de Andalucía según el sexo de profesionales y pacientes: un análisis de género.

BACKGROUND It has been identified differences of medical care practice in primary care related to physician's sex. Simultaneously, there are gender inequalities in the assignment of health resources. Both aspects give rise to an increasing growing interest in the management and provision of health services. OBJECTIVES To examine the differences in the referral practice made by female and male primary care physicians working in health centers in Andalusia, to consider whether there are disparities in referrals received by men and women, and to examine the interaction between patient's sex and physician's sex. METHODS Observational, cross-sectional, and multicenter study. POPULATION 4 health districts in Andalucía and their physicians. SAMPLE 382 physicians. MEASUREMENTS referral rate per visit (RV), referral rate per patient quota (RQ), patient's sex, physician: sex, age, postgraduate family medicine specialty, size of the patient quota by sex, mean number of patients/day by sex, mean age of the patient quota by sex, and proportion of men in the quota. Health center: urban / rural, size of the team, enrolled population, and postgraduate family medicine specialty's accreditation. SOURCES databases of health districts. PERIOD OF STUDY 2010. ANALYSIS Bivariate and multivariate multilevel analysis of the referral rate per visit with mixed Poisson model. RESULTS In 2010 382 physicians made 129,161 referrals to specialized care. The RQ was 23.47 and the RV was 4.92. The RQ in women and men was 27.23 and 19.78 for women physicians, being 27.37 and 19.51 for male physicians. The RV in women and men was 4.92 and 5.48 for women physicians, being 4.54 and 4.93 for male physicians. CONCLUSION There are no differences in referral according to physician's sex. However, there are signs that might indicate the existence of gender inequality, and women patient received less referrals. There are no physician-patient's sex interaction.

Inconspicuous assessment of diet-induced thermogenesis using whole-body indirect calorimetry.

We report a novel technique for computing diet-induced thermogenesis using data from 24-h respiration chamber measurements of 76 subjects. Physical activity (PA) was determined using a radar system to assess its duration and an accelerometer to evaluate its intensity. The regression line relating PA and energy expenditure facilitated calculation of the integrated thermogenic response to the total energy ingested (11.4% ± 3.8%), which is consistent with the values classically reported in the literature (10%) at the group level.

The Rise of The Swiss Tax Haven in the Interwar Period: An International Comparison

The history of tax havens is still little known for the decades before World War II. Up to now the studies that have focused on the 1920s and 30s have presented either a very general perspective on the development of tax havens or a narrow national point of view. Based on unpublished historical archives of four countries, this paper offers therefore a new comparative look on international tax competition during this period in order to answer the following question: was the Swiss case - already considered as a quintessential tax haven at the time - specific in comparison to other banking centres? This research has two results. On the one hand, the 1920s and 30s appear as something of a golden age of opportunity for avoiding taxation through the relocation of assets. Actually, most of the financial centres granted consistent tax benefits for imported capital, while the extremely limited degree of international cooperation and the usual guarantee of banking secrecy in European countries prevented the taxation of exported assets. On the other hand, within this general balance sheet, the fiscal strategies of a tax haven like Switzerland differed from those of a great financial power like Great Britain. Whereas the Swiss administration readily placed itself at the service of the bankers, the British policy was more balanced between the contradictory interests of the Board of Inland Revenue, the Treasury and the English business circles.

Increased condom use without other major changes in sexual behavior among the general population in Switzerland.

The expression of DNA topoisomerase II alpha and beta genes was studied in murine normal tissues. Northern blot analysis using probes specific for the two genes showed that the patterns of expression were different among 22 tissues of adult mice. Expression levels of topoisomerase II alpha gene were high in proliferating tissues, such as bone marrow and spleen, and undetectable or low in 17 other tissues. In contrast, high or intermediate expression of topoisomerase II beta gene was found in a variety of tissues (15) of adult mice, including those with no proliferating cells. Topoisomerase II gene expression was also studied during murine development. In whole embryos both genes were expressed at higher levels in early than late stages of embryogenesis. Heart, brain and liver of embryos two days before delivery, and these same tissues plus lung and thymus of newborn (1-day-old) mice expressed appreciable levels of the two genes. Interestingly, a post-natal induction of the beta gene expression was observed in the brain but not in the liver; conversely, the expression of the alpha gene was increased 1 day after birth in the liver but not in the brain. However, gene expression of a proliferation-associated enzyme, thymidylate synthase, was similar in these tissues between embryos and newborns. Thus, the two genes were differentially regulated in the post-natal period, and a tissue-specific role may be suggested for the two isoenzymes in the development of differentiated tissues such as the brain and liver. Based on the differential patterns of expression of the two isoforms, this analysis indicates that topoisomerase II alpha may be a specific marker of cell proliferation, whereas topoisomerase II beta may be implicated in functions of DNA metabolism other than replication.

Revision of the genus acrochordiceras hyatt, 1877 (Ammonoidea, Middle Triassic): Morphology, biometry, biostratigraphy and intra-specific variability

The family Acrochordiceratidae Arthaber, 1911 ranges in age from latest Spathian to the middle/late Anisian boundary, and it represents a major component of ammonoid faunas during that time. The middle Anisian genus Acrochordiceras Hyatt, 1877 is the most widespread taxon of the family and occurs abundantly worldwide within the low paleolatitude belt. However, there is a profusion of species names available for Acrochordiceras. This excessive diversity at the species level essentially results from the fact that sufficiently large samples were not available, thus leading to a typological approach to its taxonomy. Based on new extensive collections obtained from the Anisian (Middle Triassic) Fossil Hill Member (Star Peak Group, north-west Nevada) for which a high resolution biostratigraphic frame is available, the taxonomy and biostratigraphy of the genus Acrochordiceras Hyatt, 1877 is herein revised with respect to its intra-specific variation. Morphological and biometric studies (c. 550 bedrock-controlled specimens were measured) show that only one species occurs in each stratigraphic level. Continuous ranges of intra-specific variation of studied specimens enable us to synonymize Haydenites Diener, 1907, Silesiacrochordiceras Diener, 1916 and Epacrochordiceras Spath, 1934 with Acrochordiceras Hyatt, 1877. Three stratigraphically successive species are herein recognized in the low paleolatitude middle Anisian faunas from Nevada: A. hatschekii (Diener, 1907), A. hyatti Meek, 1877 and A. carolinae Mojsisovics, 1882. Moreover, an assessment of intra-specific variation of the adult size range does not support recognition of a dimorphic pair (Acrochordiceras and Epacrochordiceras) as previously suggested by other workers (Epacrochordiceras is the compressed and weakly ornamented end-member variant of Acrochordiceras). The successive middle Anisian species of Acrochordiceras form an anagenetic lineage characterized by increasing involution, adult size and intra-specific variation. This taxonomic revision based on new bedrock-controlled collections is thus an important prerequisite before studying the evolution of the group.

Gender difference in the response to an angiotensin-converting enzyme inhibitor and a diuretic in hypertensive patients of African descent.

BACKGROUND: The efficacy of angiotensin-converting enzyme (ACE) inhibitors in decreasing blood pressure in African patients is controversial. OBJECTIVE: We examined the ambulatory blood pressure (ABP) response to a diuretic and an ACE inhibitor in hypertensive patients of East African descent and evaluated the individual characteristics that determined treatment efficacy. DESIGN: A single-blind randomized AB/BA crossover design. SETTING: Hypertensive families of East African descent from the general population in the Seychelles. PARTICIPANTS: Fifty-two (29 men and 23 women) out of 62 eligible hypertensive patients were included.Main outcome measures ABP response to 20 mg lisinopril (LIS) daily and 25 mg hydrochlorothiazide (HCT) daily given for a 4-week period.Results The daytime systolic/diastolic ABP response to HCT was 4.9 [95% confidence interval (CI) 1.2-8.6]/3.6 (1.0-6.2) mmHg for men and 12.9 (9.2-16.6)/6.3 (3.7-8.8) mmHg for women. With LIS the response was 18.8 (15.0-22.5)/14.6 (12.0-17.1) mmHg for men and 12.4 (8.7-16.2)/7.7 (5.1-10.2) mmHg for women. The night-time systolic/diastolic response to HCT was 5.0 (0.6-9.4)/2.7 [(-0.4)-5.7] mmHg for men and 11.5 (7.1-16.0)/5.7 (2.6-8.8) mmHg for women, and to LIS was 18.7 (14.2-22.1)/15.4 (12.4-18.5) mmHg for men and 3.5 [(-1.0)-7.9]/2.3 [(-0.8)-5.4] mmHg for women. Linear regression analyses showed that gender is an independent predictor of the ABP responses to HCT and to LIS. CONCLUSIONS: Hypertensive patients of African descent responded better to LIS than to HCT. Men responded better to LIS than to HCT and women responded similarly to both drugs.

Predictive accuracy and usefulness of calibration of the ESC SCORE in Switzerland.

BACKGROUND: Prevention of cardiovascular disease (CVD) at the individual level should rely on the assessment of absolute risk using population-specific risk tables. OBJECTIVE: To compare the predictive accuracy of the original and the calibrated SCORE functions regarding 10-year cardiovascular risk in Switzerland. DESIGN: Cross-sectional, population-based study (5773 participants aged 35-74 years). METHODS: The SCORE equation for low-risk countries was calibrated based on the Swiss CVD mortality rates and on the CVD risk factor levels from the study sample. The predicted number of CVD deaths after a 10-year period was computed from the original and the calibrated equations and from the observed cardiovascular mortality for 2003. RESULTS: According to the original and calibrated functions, 16.3 and 15.8% of men and 8.2 and 8.9% of women, respectively, had a 10-year CVD risk > or =5%. Concordance correlation coefficient between the two functions was 0.951 for men and 0.948 for women, both P<0.001. Both risk functions adequately predicted the 10-year cumulative number of CVD deaths: in men, 71 (original) and 74 (calibrated) deaths for 73 deaths when using the CVD mortality rates; in women, 44 (original), 45 (calibrated) and 45 (CVD mortality rates), respectively. Compared to the original function, the calibrated function classified more women and fewer men at high-risk. Moreover, the calibrated function gave better risk estimates among participants aged over 65 years. CONCLUSION: The original SCORE function adequately predicts CVD death in Switzerland, particularly for individuals aged less than 65 years. The calibrated function provides more reliable estimates for older individuals.

Peritalar dislocations: a retrospective study of 18 cases.

The purpose of this study is to retrospectively evaluate 18 consecutive cases of peritalar dislocations referred to our department during a period of 25 years and to delineate the factors influencing long-term prognosis. There were 13 (73%) medial and 5 (27%) lateral dislocations. Six patients (33%) suffered an open injury, including 2 of 13 (15%) medial and 4 of 5 (80%) lateral dislocations. Associated fractures involving the hindfoot or forefoot were noted in 7 feet, including 3 of 5 lateral dislocation cases. Reduction was accomplished under general anesthesia; in no case was open reduction necessary. In 4 of 6 open injuries with associated fractures, temporary fixation with Kirschner wires was performed. Patients were immobilized in a plaster cast for 4 weeks, or for 6 weeks in the presence of fracture, followed by weightbearing as tolerated. At a mean follow-up of 10.2 years (range, 4 to 26 years), 10 patients (56%) showed excellent results; all had sustained a closed medial low-energy dislocation. There were 3 cases (17%) with fair results and 5 cases (28%) with poor results. Forty-five percent of patients showed a restriction of activity, a reduction of subtalar range of motion, and moderate or severe radiographic signs of hindfoot degenerative arthritis. There were no cases of talar avascular necrosis, and in no case was secondary surgery necessary. Lateral dislocation and open medial dislocations with concomitant fractures showed a greater potential for poor prognosis. The results were independent from period of cast immobilization, suggesting that 4 to 6 weeks of immobilization provides acceptable long-term results.

Descemet membrane detachment after nonpenetrating filtering surgery.

PURPOSE: To make surgeons performing nonpenetrating filtering surgery aware of an unusual complication namely Descemet membrane detachment. METHODS: We retrospectively reviewed nine eyes of nine patients seen in our hospital with Descemet membrane detachment occurring after nonpenetrating filtering surgery from January 1994 to December 2000. RESULTS: Both planar and nonplanar detachments were reported. Neither scrolls nor tears in the Descemet membrane were observed in any patient. After viscocanalostomy (four patients), the detachment was generally noticed shortly after the procedure and the cornea maintained its clarity. After deep sclerectomy with a collagen implant (five patients), it developed weeks to months postoperatively with adjacent corneal edema. Four patients had descemetopexy. None required more than one procedure. However, at the last visit, two detachments persisted although they had diminished in size: one after viscocanalostomy and conservative treatment and one after descemetopexy after deep sclerectomy with a collagen implant. To date otherwise, no signs of significant corneal damage could be observed clinically nor by specular microscopy and pachymetry. CONCLUSIONS: The diagnosis of Descemet membrane detachment can be easily overlooked or misdiagnosed. The clinical presentation, clinical course, and pathogenesis depend on the type of nonpenetrating filtering surgery performed. Ophthalmologists should be aware of this unusual complication, which is likely to be more common after nonpenetrating filtering surgery than after trabeculectomy. A period of observation before attempting descemetopexy is recommended.

Impact of inadequate empirical therapy on the mortality of patients with bloodstream infections: a propensity score-based analysis.

The impact of the adequacy of empirical therapy on outcome for patients with bloodstream infections (BSI) is key for determining whether adequate empirical coverage should be prioritized over other, more conservative approaches. Recent systematic reviews outlined the need for new studies in the field, using improved methodologies. We assessed the impact of inadequate empirical treatment on the mortality of patients with BSI in the present-day context, incorporating recent methodological recommendations. A prospective multicenter cohort including all BSI episodes in adult patients was performed in 15 hospitals in Andalucía, Spain, over a 2-month period in 2006 to 2007. The main outcome variables were 14- and 30-day mortality. Adjusted analyses were performed by multivariate analysis and propensity score-based matching. Eight hundred one episodes were included. Inadequate empirical therapy was administered in 199 (24.8%) episodes; mortality at days 14 and 30 was 18.55% and 22.6%, respectively. After controlling for age, Charlson index, Pitt score, neutropenia, source, etiology, and presentation with severe sepsis or shock, inadequate empirical treatment was associated with increased mortality at days 14 and 30 (odds ratios [ORs], 2.12 and 1.56; 95% confidence intervals [95% CI], 1.34 to 3.34 and 1.01 to 2.40, respectively). The adjusted ORs after a propensity score-based matched analysis were 3.03 and 1.70 (95% CI, 1.60 to 5.74 and 0.98 to 2.98, respectively). In conclusion, inadequate empirical therapy is independently associated with increased mortality in patients with BSI. Programs to improve the quality of empirical therapy in patients with suspicion of BSI and optimization of definitive therapy should be implemented.

The Distant neighbors — EU, Middle East, North Africa and the Euro-Mediterranean Partnership

The Barcelona Euro-Mediterranean Conference (1995) was intended to be a launching pad" for creating a new, innovative relationship between the EU-Fifteen and a selected set of non-member Middle Eastern and North African countries. The Barcelona Process was to become the European Union´s first attempt, of several, to create postmodern inclusive policy spheres as a way to deal with the post-enlargement problems of ´ins´ and outs´ in its immediate periphery. Nevertheless, in spite of geographical proximity, common problems and stated interest in creating amorphous EU borders in different sectors, the Euro-Mediterranean Partnership is today all but abandoned. This paper will examine some of the factors behind the current degeneration of the EU´s post-bipolar foreign policy strategy in the Mediterranean, by exploring the dialectic between the Union´s desire to expand its geopolitical, economic and cultural boundaries and the need to secure its territorial area (from migration, proliferation, social instability etc.). In the final part of the paper some suggestions for how to revive the relationship across the Mare Nostrum will be forwarded.

Real-life versus package insert: a post-marketing study on adverse-event rates of the virosomal hepatitis A vaccine Epaxal® in healthy travellers.

There are various methods to collect adverse events (AEs) in clinical trials. The methods how AEs are collected in vaccine trials is of special interest: solicited reporting can lead to over-reporting events that have little or no biological relationship to the vaccine. We assessed the rate of AEs listed in the package insert for the virosomal hepatitis A vaccine Epaxal(®), comparing data collected by solicited or unsolicited self-reporting. In an open, multi-centre post-marketing study, 2675 healthy travellers received single doses of vaccine administered intramuscularly. AEs were recorded based on solicited and unsolicited questioning during a four-day period after vaccination. A total of 2541 questionnaires could be evaluated (95.0% return rate). Solicited self-reporting resulted in significantly higher (p<0.0001) rates of subjects with AEs than unsolicited reporting, both at baseline (18.9% solicited versus 2.1% unsolicited systemic AEs) and following immunization (29.6% versus 19.3% local AEs; 33.8% versus 18.2% systemic AEs). This could indicate that actual reporting rates of AEs with Epaxal(®) may be substantially lower than described in the package insert. The distribution of AEs differed significantly between the applied methods of collecting AEs. The most common AEs listed in the package insert were reported almost exclusively with solicited questioning. The reporting of local AEs was more likely than that of systemic AEs to be influenced by subjects' sex, age and study centre. Women reported higher rates of AEs than men. The results highlight the need for detailing the methods how vaccine tolerability was reported and assessed.

Energy expenditure in obese women before and during weight loss, after refeeding, and in the weight-relapse period.

In 10 moderately obese women, 24-h energy expenditure (24EE) was measured in a respiration chamber under four conditions: 1) before weight loss (body weight = 77.9 kg), 2) during weight loss (63.9 kg), 3) after realimentation (62.5 kg), and 4) 6-15 mo after the study diet with ad libitum diet (67.7 kg). The 14 +/- 8 kg (mean +/- SD) weight loss produced a decrease in 24EE of 1498 +/- 1138 kJ/d (P < 0.001), ie, a decrease of weight of 107 kJ.kg body wt-1.d-1. The subsequent 24EE (conditions 3 and 4) remained lower than the value before weight loss. A significant correlation was found between changes before and after weight regain in basal respiratory quotient (RQ) and the spontaneous rate of body-weight gain after cessation of the period of low energy intake (r = 0.89, P < 0.01); this suggests that the value of the postabsorptive RQ may be a predictor of relapse of weight gain. After discontinuation of the low energy diet, an elevated postabsorptive RQ shows that the endogenous lipid oxidation is low, a condition favoring weight gain.

Mycobacterium tuberculosis transmission in a country with low tuberculosis incidence: role of immigration and HIV infection.

Immigrants from high-burden countries and HIV-coinfected individuals are risk groups for tuberculosis (TB) in countries with low TB incidence. Therefore, we studied their role in transmission of Mycobacterium tuberculosis in Switzerland. We included all TB patients from the Swiss HIV Cohort and a sample of patients from the national TB registry. We identified molecular clusters by spoligotyping and mycobacterial interspersed repetitive-unit-variable-number tandem-repeat (MIRU-VNTR) analysis and used weighted logistic regression adjusted for age and sex to identify risk factors for clustering, taking sampling proportions into account. In total, we analyzed 520 TB cases diagnosed between 2000 and 2008; 401 were foreign born, and 113 were HIV coinfected. The Euro-American M. tuberculosis lineage dominated throughout the study period (378 strains; 72.7%), with no evidence for another lineage, such as the Beijing genotype, emerging. We identified 35 molecular clusters with 90 patients, indicating recent transmission; 31 clusters involved foreign-born patients, and 15 involved HIV-infected patients. Birth origin was not associated with clustering (adjusted odds ratio [aOR], 1.58; 95% confidence interval [CI], 0.73 to 3.43; P = 0.25, comparing Swiss-born with foreign-born patients), but clustering was reduced in HIV-infected patients (aOR, 0.49; 95% CI, 0.26 to 0.93; P = 0.030). Cavitary disease, male sex, and younger age were all associated with molecular clustering. In conclusion, most TB patients in Switzerland were foreign born, but transmission of M. tuberculosis was not more common among immigrants and was reduced in HIV-infected patients followed up in the national HIV cohort study. Continued access to health services and clinical follow-up will be essential to control TB in this population.
