National and regional prevalence of interpersonal violence from others' alcohol use: a systematic review and modelling study

Background

While alcohol use is an established risk factor for interpersonal violence, the extent to which people are affected by interpersonal violence from others' drinking has not yet been quantified for different world regions. This modelling study aims to provide the first estimates of the national and regional prevalence of interpersonal violence from others' drinking.

Methods

An international systematic literature search (02/28/2023, Prospero: CRD42022337364) was conducted to identify general adult population studies assessing the prevalence of interpersonal violence from others' drinking with no restrictions to publication date or language. Reports that did not provide data on interpersonal violence from others' drinking (primary outcome), were no original research studies, or captured a selected group of people only, were excluded. Observed prevalence data were extracted and used to build fractional response regression models to predict past-year prevalence of emotional and physical violence from others' drinking in 2019. Random-effects meta-regression models were used to aggregate the observed prevalence of sexual and intimate partner violence. Study risk of bias (ROB) was assessed using a modified version of the Newcastle-Ottawa Scale.

Findings

Out of 13,835 identified reports, 50 were included covering just under 830,000 individuals (women: 347,112; men: 322,331; men/women combined: 160,057) from 61 countries. With an average prevalence of 16·8% (95% CI: 15·2-18·3%) and 28·3% (95% CI: 23·9-32·4%) in men and women combined in the GBD super regions High Income and Central Europe, Eastern Europe, & Central Asia, respectively, emotional violence was the most common form of interpersonal violence from others' drinking. Physical violence averaged around 3% (women) and 5% (men) in both regions. The pooled prevalence of sexual violence from others' drinking in men and women was 1·3% (95% CI: 0·5-3·3%, 95% PI: 0·1-16·9%) and 3·4% (95% CI: 1·4-8·3%, 95% PI: 0·2-35·3%), respectively, and ranged between 0·4% (95% CI: 0·1-1·6%, 95% PI: 0·0-7·3%) and 2·7% (95% CI: 1·1-6·3%, 95% PI: 0·2-30·0%) for different forms of intimate partner violence. ROB was moderate or critical for most reports; accounting for critical ROB did not substantially alter our results.

Interpretation

The share of the population experiencing harms from others' drinking is significant and should be an integral part of public health strategies.

Restricting alcohol marketing to reduce alcohol consumption: A systematic review of the empirical evidence for one of the 'best buys'

BACKGROUND AND AIMS

Even though a ban of alcohol marketing has been declared a 'best buy' of alcohol control policy, comprehensive systematic reviews on its effectiveness to reduce consumption are lacking. The aim of this paper was to systematically review the evidence for effects of total and partial bans of alcohol marketing on alcohol consumption.

METHODS

This descriptive systematic review sought to include all empirical studies that explored how changes in the regulation of alcohol marketing impact on alcohol consumption. The search was conducted between October and December 2022 considering various scientific databases (Web of Science, PsycINFO, MEDLINE, Embase) as well as Google and Google Scholar. The titles and abstracts of a total of 2572 records were screened. Of the 26 studies included in the full text screening, 11 studies were finally included in this review. Changes in consumption in relation to marketing bans were determined based on significance testing in primary studies. Four risk of bias domains (confounding, selection bias, information bias and reporting bias) were assessed.

RESULTS

Seven studies examined changes in marketing restrictions in one location (New Zealand, Thailand, Canadian provinces, Spain, Norway). In the remaining studies, between 17 and 45 locations were studied (mostly high-income countries from Europe and North America). Of the 11 studies identified, six studies reported null findings. Studies reporting lower alcohol consumption following marketing restrictions were of moderate, serious and critical risk of bias. Two studies with low and moderate risk of bias found increasing alcohol consumption post marketing bans. Overall, there was insufficient evidence to conclude that alcohol marketing bans reduce alcohol consumption.

CONCLUSIONS

The available empirical evidence does not support the claim of alcohol marketing bans constituting a best buy for reducing alcohol consumption.

Cannabis use, health problems, and criminal offences in Germany: national and state-level trends between 2009 and 2021

The German federal government plans to decriminalise cannabis. The impact of this policy on use prevalence, cannabis-related health and legal problems cannot be fully anticipated and should be viewed in context with current trends. We used routine data on (a) cannabis use (population-based surveys), (b) cannabis-related diagnoses (ICD-10 code F12) in outpatient medical settings and (c) minor law offences (registered violations against the narcotics law for possessing small amounts) to analyse age and sex-specific trends by federal state between 2009 and 2021. To enable comparisons across time and federal state besides crude prevalence rates, age-standardised rates were calculated. Between 2009 and 2021, the age-standardised prevalence of cannabis use (5.7-10.6%), rate of diagnoses (1.1-3.7 per 1,000), and legal offences (1.8-3.1 per 1,000) increased, with the largest increase noted for cannabis-related diagnoses. Relatively, increases were most pronounced for older users (40-to-59-year-olds: use and offences; 35-to-44-year-olds: cannabis-related diagnoses) and rather stagnant for minors. Cannabis use and health problems appear to be more pronounced in Northern and city states, while no clear geographic trend was observed for law offences. Cannabis-related outpatient treatment demand has risen more steeply than use prevalence suggesting an increasing challenge for the health care system. Despite rising rates for documented offences, the long-term implications of law violations on social and occupational life are poorly understood but may be considered for evaluations of the proposed law changes.

Alcohol use, dementia risk, and sex: a systematic review and assessment of alcohol-attributable dementia cases in Europe

BACKGROUND

High-risk alcohol use is an established modifiable risk factor for dementia. However, prior reviews have not addressed sex differences in alcohol-related dementia risk. In this systematic review, we take a sex-specific perspective towards the alcohol-dementia link, taking into account the age of dementia onset.

METHODS

We searched electronic databases for original cohort or case-control studies investigating the association between alcohol use and dementia. Two restrictions were considered: First, studies had to report results stratified by sex. Second, given the fact that the age at dementia onset seems to affect the alcohol-dementia link, studies were required to distinguish between early-onset and late-onset dementia (cut-off: 65 years). Additionally, the contribution of alcohol to dementia incidence was quantified for a set of 33 European countries for the year 2019.

RESULTS

We reviewed 3,157 reports, of which 7 publications were finally included and summarised narratively. A lower dementia risk when drinking alcohol infrequent or at moderate levels was found in men (three studies) and women (four studies). High-risk use and alcohol use disorders increased the risk of mild cognitive impairment and dementia, particularly early-onset dementia. Estimating the alcohol-attributable share of incident dementia cases revealed that 3.2% and 7.8% of incident dementia cases were estimated to be attributable to high-risk alcohol use (at least 24 g of pure alcohol per day) in 45-to-64-year-old women and men, respectively.

CONCLUSIONS

Research to date has paid little attention to the sex-specific link of alcohol and dementia. In the absence of sex-specific research, the established recommendations on high-risk alcohol use should be employed to communicate the alcohol-attributable dementia risk.

The ESC ACCA EAPCI EORP acute coronary syndrome ST-elevation myocardial infarction registry

Aims 

The Acute Cardiac Care Association (ACCA)–European Association of Percutaneous Coronary Intervention (EAPCI) Registry on ST-elevation myocardial infarction (STEMI) of the EurObservational programme (EORP) of the European Society of Cardiology (ESC) registry aimed to determine the current state of the use of reperfusion therapy in ESC member and ESC affiliated countries and the adherence to ESC STEMI guidelines in patients with STEMI.

Methods and results 

Between 1 January 2015 and 31 March 2018, a total of 11 462 patients admitted with an initial diagnosis of STEMI according to the 2012 ESC STEMI guidelines were enrolled. Individual patient data were collected across 196 centres and 29 countries. Among the centres, there were 136 percutaneous coronary intervention centres and 91 with cardiac surgery on-site. The majority of centres (129/196) were part of a STEMI network. The main objective of this study was to describe the demographic, clinical, and angiographic characteristics of patients with STEMI. Other objectives include to assess management patterns and in particular the current use of reperfusion therapies and to evaluate how recommendations of most recent STEMI European guidelines regarding reperfusion therapies and adjunctive pharmacological and non-pharmacological treatments are adopted in clinical practice and how their application can impact on patients’ outcomes. Patients will be followed for 1 year after admission.

Conclusion 

The ESC ACCA-EAPCI EORP ACS STEMI registry is an international registry of care and outcomes of patients hospitalized with STEMI. It will provide insights into the contemporary patient profile, management patterns, and 1-year outcome of patients with STEMI.

Abstract P3-13-08: Preclinical validation of a new tumor imaging agent targeting αvβ3 to detect breast tumor using NIR-light imaging

Surgery is still a essential step for breast cancer treatment. Complete tumor removal during surgery rely on surgeon's ability to differentiate tumor from normal tissue. To date, no intra operative method is available and reliable enough to help the surgeon delineate precisely tumor extension in the adjacent normal tissue. Thus, surgeons rely solely on pre operative imaging techniques to delineate tumor margins. Recent advances made in the field of non-invasive imaging and vectorized nano-size particles have revealed a remarkable potential for improved tumor-margin detection. AngiostampTM is a new fluorescent agent for intra operative imaging. This system provides strong binding on αvβ3 integrin-rich tumor neoangiogenesis. Our general hypothesis is that targeting αvβ3 integrin-rich breast carcinoma neoangiogenesis should provide improved delivery of diagnostic compounds and assist surgeons intra operatively using near-infrared imaging techniques.

We conducted preclinical studies to evaluate the distribution of angiostampTM in vivo in murine breast tumor model and to determine the expression of αvβ3 integrin on human breast specimens.

The capacity of AngiostampTM to target αvβ3 integrin was assessed in 4T1 breast tumor model. After tumor implantation, mices were injected with AngiostampTM or a saline solution. Detection of the tumors was performed at different timepoints (early, progressive and established tumors, N= 24 mices/timepoint) using near infrared (NIR) imaging system (FluobeamTM) to detect fluorescence in tumor tissue.

In parallel, the expression of αvβ3 integrins in normal breast tissue, benign lesions (N=20) and various tumors subtypes (N=120) was assessed by immunohistochemistry.

In mice injected with AngiostampTM, fluorescence was observed only within the tumors with low background. AngiostampTM labeled tumors at all timepoint. No false negative fluorescence was found as confirmed by histopathological analyses.

In humans, the αvβ3 integrin are expressed in normal breast epithelial cells and benign metaplastic or proliferative epithelial lesions. However, due to the density of carcinomatous cells, the level of expression was much higher in breast cancer: 94% of invasive ductal carcinomas and 100% of invasive lobular carcinomas had a membranous staining (moderate to high intensity). Expression in breast cancer was not restricted to tumor subtypes neither hormone receptor expression nor SBR grade.

Based on this preclinical demonstration, AngiostampTM could allow a better intra-operative detection of tumor bed in breast cancer, increasing the efficiency of surgical procedure especially for infraclinic disease and decreasing the rate of second surgery. Preclinical development is ongoing and the first clinical trial is expected in 2017.

Influence of 25-hydroxyvitamin D3 and 1,25-dihydroxyvitamin D3 on expression of P-glycoprotein and cytochrome P450 3A in sheep

In order to improve calcium and phosphorus balance, beef cattle and dairy cows can be supplemented with vitamin D. However, different vitamin D metabolites have been shown to increase expression of P-glycoprotein (P-gp, MDR1, ABCB1) and cytochrome P450 3A (CYP3A) in rodents as well as in cell culture systems. As such interferences might have an impact on pharmacokinetics of some drugs widely-used in veterinary medicine, we investigated the expression of P-gp, CYP3A, vitamin D receptor (VDR), pregnane X receptor (PXR) and retinoid X receptor α (RXRα) in sheep either treated orally with 6μg/kg body weight (BW) 25-hydroxyvitamin D₃ (OHD₃) for ten days before sacrifice or 12h after intravenous injection of 0.5μg/kg BW 1,25-dihydroxyvitamin D₃ (1,25- (OH)₂D₃). Down-regulation of ruminal, jejunal and hepatic, but not renal P-gp could be found with 25-OHD₃ supplementation. Interestingly, this effect on P-gp was not observed in tissues from 1,25-(OH)₂D₃-treated sheep. In contrast, 1,25-(OH)₂D₃ induced a significant up-regulation of renal and jejunal CYP3A expression, while 25-OHD₃ had no impact. Renal expression of VDR and PXR was also increased by treatment with 1,25-(OH)₂D₃, while jejunal PXR expression was only stimulated in sheep supplemented with 25-OHD₃. Either treatments increased renal, but not ruminal, jejunal or hepatic expression of RXRα. These results demonstrate that the impact of large doses of vitamin D metabolites on different target organs and potential interactions with other medications should be further investigated in vitro and in vivo to understand the effects of vitamin D metabolites on metabolism and excretion pathways in livestock.

[The TraumaRegister DGU® as the basis of medical quality management. Ten years experience of a national trauma centre exemplified by emergency room treatment]

BACKGROUND

The trauma register of the German Society of Trauma Surgery (TraumaRegister DGU®/TR-DGU) has been proven to be a valuable tool for external assessment of quality in the treatment of patients with major trauma. This publication shows for the first time how the quality of trauma treatment in a level I trauma centre could be improved over a period of almost ten years with the help of continuous quality management, i.e. recognizing a problem, developing a solution and evaluating its effect.

MATERIALS AND METHODS

Tracer parameters and indicators of quality are presented in four periods over a total study period from 1st January 1989 to 31st March 2007. The division into four periods is due to major changes in the trauma treatment algorithms or structural changes in the trauma room. The results are displayed for all patients treated in the trauma room and for those patients with an injury severity score (ISS)≥16.

RESULTS

Over all four periods a total number of n=2,239 patients were admitted to the trauma room. Based on the results of the trauma register a number of changes were made, not only structural changes, such as the introduction of point-of-care diagnostics, initially conventional X-ray, then digital X-ray and finally multislice computed tomography (CT) scanning in the trauma room but also changes in the way personnel participating in the trauma treatment are trained. Advanced trauma life support (ATLS®) has become the standard training for doctors and prehospital trauma life support (PHTLS®) for nurses. Time efficient treatment algorithms were introduced. All measures led to changes in several parameters which are chosen as indicators for good treatment quality. It was for instance possible to reduce the average total trauma treatment time for patients with an ISS≥16 from initially 90.9±48.6 min to 37.4±18.  min in the final study period.

CONCLUSIONS

The external quality management performed by the TR-DGU has proved to be a constant source of inspiration. The effects of the changes made can be scientifically proven. It is to be discussed to what extent a sole external quality management can be useful.

Intestinal glucose absorption in calves as affected by different carbohydrate sources

From numerous recent studies, it has been demonstrated that the development of the forestomach system in ruminants and thus microbial carbohydrate fermentation do not exclude the potential of the small intestines for enzymatic carbohydrate digestion and subsequent monosaccharide absorption. However, the role of regulatory nutritional factors is still under discussion. Therefore, we investigated the kinetic parameters of intestinal Na(+) -dependent glucose absorption and SGLT1 expression using isolated brush border membrane vesicles (BBMV) from the jejunum of 10-week-old calves kept on either hay, concentrate or corn silage-based diets in addition to milk replacer. While the maximal transport capacity was significantly higher for concentrate and corn silage-fed animals, SGLT1 protein expression was highest in BBMV isolated from hay-fed animals. This observation differs from the prevalent conception that induction of Na(+) -dependent glucose uptake via SGLT1 is based on an increased number of transporters at the brush border membrane.

Organspende in der Schweiz

Seit 1985 koordiniert Swisstransplant die Allokation für die Organtransplantation in der Schweiz. In diesen 20 Jahren hat die Anzahl der Leichenspender tendenziell ab- und die der Lebendspender zugenommen. Gleichzeitig hat die Anzahl Patienten auf Wartelisten für eine Organtransplantation zugenommen, aktuell sind es über 1000. 412 Personen wurden 2004 transplantiert, 43 (= 4%) sind auf der Warteliste verstorben. Im Vergleich zum übrigen Europa ist die Spendefrequenz für die Leichenspende in der Schweiz mit 13 Organspendern/ Mio Einwohner relativ niedrig. Um die hohe Anzahl Patienten auf Wartelisten mit einer Organtransplantation behandeln zu können, müssen in Zukunft zusätzliche Anstrengungen unternommen werden. Diese betreffen die Entwicklung von alternativen Therapien zur Verhinderung oder Behandlung von Organversagen, die Verbesserung der Rahmenbedingungen für die Transplantation durch das neue Transplantationsgesetz, vermehrte Ressourcen und Kenntnisse zur Spenderevaluation und Ausweitung des Spenderpools in den Spenderkliniken, weitere Optimierung des Organallokationsprozesses, verstärkte Information und Motivation der Bevölkerung durch die Patientenorganisationen, die Ärzteschaft, Swisstransplant und allenfalls öffentliche Mittel.

Kontrastverstärkte MR-Angiographie (CEMRA) bei peripherer AVK (pAVK): konventionelle Tischverschiebetechnik versus Hybrid-Technik

PURPOSE

In peripheral arterial occlusive disease (PAOD), angiographic evaluation of the entire aortopedal arterial system is mandatory. In a randomized study, two different protocols of CEMRA were evaluated prospectively to compare their diagnostic quality and clinical usefulness.

PATIENTS AND METHODS

80 patients (males n = 60, females n = 20, median age = 70 years, diabetics n = 27) with PAOD were examined with a 1.5 T system (40 mT/m) using a dedicated phased array peripheral vascular coil. Protocol A consisted of a single injection of Gd-BOPTA with consecutive craniocaudal image acquisition and protocol B of two injections, with the first injection of Gd-BOPTA followed by image acquisition of the popliteocrural and pedal segments and the second injection followed by acquiring the aortoiliac and femoral segments (hybrid technique). The evaluation of the arterial system was directed to the iliac, femoral, popliteocrural and pedal arteries.

RESULTS

The visualization of the entire aortopedal vascular system was of diagnostically good or satisfactory quality in 16 of 40 patients using protocol A and in 29 of 40 patients using protocol B (iliac 40 vs. 37, femoral 40 vs. 40, popliteocrural 35 vs. 37, pedal 16 vs. 29); without the pedal station the number increased to 35 of 40 patients for both protocols. The reason of diagnostic limitations was an arteriovenous overlap in 24 of 80 cases, with 19 of 40 cases for protocol A and 5 of 40 for protocol B, located exclusively in the cruropedal region.

CONCLUSION

Moving table hybrid CEMRA is superior to conventional technique in craniocaudal direction by producing less venous overlap of arteries and is especially more suitable for the diagnostic evaluation of the cruropedal region.

[Sex differences in morphologic aging processes]

According to Max Bürger (2) it is justified to speak of sexual divergence of biomorphosis. Morphometrical investigations have proved the existence of such sexual differences. The following results were obtained: The first example concerns the increase of fatty tissue in parathyroid glands which we measured on histological slides of 135 human samples by means of the point counting method. The fatty tissue of males was shown to increase continuously with statistic significance, whereas this process stops in females during their generative phase between the 2nd and 5th decade. Evidence for the sexual divergence was also obtained by investigating the fatty tissue between the bundles of muscle fibers of the tongue, however, without being able to statistically verify these results. We found the same sexual differences by measuring the muscle cell regression and connective tissue proliferation in the ciliary muscle of human eyes and tunica muscularis of the small intestine as well. All findings prove that the female is able to stay biologically younger during her generative activity compared to males. After menopause the aging processes speed up in female tissues without making up for the "age lead" of males. It is also worth mentioning that macroscopic anthropometric features do confirm the same fact, e.g., length and breadth of human auricles, ranging in age from 18 to 51 years.
