Alcohol Addiction: One Entity or Different Entities? A DSM-4-Based Attempt Toward a Geographicization of Alcohol Addiction and Abuse.

AIM: To examine whether in Europe perceptions of 'alcoholism' differ in a discrete manner according to geographical area. METHOD: Secondary analysis of a data set from a European project carried out in 2013-2014 among 1767 patients treated in alcohol addiction units of nine countries/regions across Europe. The experience of all 11 DSM-4 criteria used for diagnosing 'alcohol dependence' and 'alcohol abuse' were assessed in patient interviews. The analysis was performed through Multiple Correspondence Analysis. RESULTS: The symptoms of 'alcohol dependence' and 'alcohol abuse', posited by DSM-IV, were distributed according to three discrete geographical patterns: a macro-area mainly centered on drinking beer and spirit, a culture traditionally oriented toward wine and a mixed intermediate alcoholic beverage situation. CONCLUSION: These patterns of perception seem to parallel the diverse drinking cultures of Europe.

A Commentary on the Limits of Alcoholic Beverage Policies.

Providing one set of policy measures for all countries as if they were a single, homogeneous entity does not appear to be evidence-based, according to recent research on the effectiveness of alcoholic beverage control policies. Contextual and cultural determinants-social, economic, demographic, cultural and political-appear to be major factors of influencing change in drinking trends, drinking patterns and drinking-related harms. The variable interplay between contextual determinants and alcohol control policy measures implies diverse impacts on consumption and harm according to time, and to the different countries and groups of countries. In addition, epidemiology research manifests some limitations when applied to alcohol drinking and results are transferred from one culture to another. The conditions of individual cultures and countries should be considered when planning and evaluating alcohol control policies.

A commentary about the AMPHORA study: selected caveats, comments, and considerations about its conditions of diversity, uncertainty, and unpredictability.

This point-of-view commentary explores a selected range of issues relevant to alcoholic beverage drinking and nondrinking patterns documented by the AMPHORA European study which, with hind-sight, limits its generalizability, with fore-sight are generally inadequately considered and documented and, with ordinary insight, are not likely to affect the ongoing and future behaviors of policy making and sustaining stakeholders whatever their sources of influence and whatever the levels and quality of evidence-informed data, information, and derived knowledge.

Mindfulness: and drug users as well as non-users questing among the unresolved.

"Mindfulness"-(focused attention)-in substance use intervention is explored as a concept, process, tool, and a Way, as a narrative, considering selected unresolved critical issues.

Radiographic progression of ankylosing spondylitis after up to two years of treatment with etanercept.

OBJECTIVE: To investigate the effect of etanercept therapy on radiographic progression in patients with ankylosing spondylitis (AS). METHODS: Patients with AS who had previously participated in a 24-week randomized, double-blind, placebo-controlled trial of etanercept therapy were enrolled in a 72-week open-label extension. Radiographs of the cervical and lumbar spine from patients who received etanercept (25 mg twice weekly) for up to 96 weeks were compared with radiographs from patients in a large prevalence cohort (Outcome Assessments in Ankylosing Spondylitis International Study [OASIS]) who had not been treated with anti-tumor necrosis factor alpha (anti-TNFalpha) agents. Radiographs obtained at 2 time points up to 96 weeks apart from patients in both study populations were digitized and read by 2 independent readers who were blinded with regard to patient group and sequence. The primary end point was the 96-week change in the modified Stoke AS Spine Score (mSASSS). RESULTS: A total of 257 patients treated with etanercept were compared with 175 unselected patients from the OASIS study. There was no significant difference in the change in the mSASSS from baseline among patients who received etanercept (mean +/- SD 0.91 +/- 2.45) versus those from the OASIS group (0.95 +/- 3.18). CONCLUSION: Unlike other inflammatory rheumatic diseases such as rheumatoid arthritis and psoriatic arthritis, structural progression in AS seems to be independent of TNF, despite the fact that TNF is responsible for the signs and symptoms due to inflammation in this disease.

Harm and risk reduction: history, theories, issues, and implications.

Harm reduction is explored, historically, in terms of ideologies, concepts, processes, types, stakeholders, legal, policy, service delivery, and ethical considerations and their micro and macro consequences. Necessary critical conditions underpinning ideologies and programs throughout their life cycle are examined, as are selected unresolved issues and paradoxes. Importantly, harm reduction can inadvertently result in distancing drug users (DUs) from mainstream ("normed") care by institutionalizing specialized care for DUs who remain "marginalized" from the community at large. Also, harm reduction can become harm production when program staff, who should be foster autonomy and self-care in partnership with DUs, are co-opted into becoming social control agents acting on compliant, passive, pathologized, and dehumanized stereotypes - Them.

Evaluation of tumor measurements in oncology: use of film-based and electronic techniques.

PURPOSE: To evaluate the variability in bidimensional computed tomography (CT) measurements obtained of actual tumors and of tumor phantoms by use of three measurement techniques: hand-held calipers on film, electronic calipers on a workstation, and an autocontour technique on a workstation. MATERIALS AND METHODS: Three radiologists measured 45 actual tumors (in the lung, liver, and lymph nodes) on CT images, using each of the three techniques. Bidimensional measurements were recorded, and their cross-products calculated. The coefficient of variation was calculated to assess interobserver variability. CT images of 48 phantoms were measured by three radiologists with each of the techniques. In addition to the coefficient of variation, the differences between the cross-product measurements of tumor phantoms themselves and the measurements obtained with each of the techniques were calculated. RESULTS: The differences between the coefficients of variation were statistically significantly different for the autocontour technique, compared with the other techniques, both for actual tumors and for tumor phantoms. There was no statistically significant difference in the coefficient of variation between measurements obtained with hand-held calipers and electronic calipers. The cross-products for tumor phantoms were 12% less than the actual cross-product when calipers on film were used, 11% less using electronic calipers, and 1% greater using the autocontour technique. CONCLUSION: Tumor size is obtained more accurately and consistently between readers using an automated autocontour technique than between those using hand-held or electronic calipers. This finding has substantial implications for monitoring tumor therapy in an individual patient, as well as for evaluating the effectiveness of new therapies under development.

Substance use intervention failure: a point of view or how the cure becomes the disease or an ode to experts on incurability or masking the disease, mitigating someone's pain but providing no basic cure/solution.

Substance use intervention, both in the private and public sectors, continues to be associated with failure. This paper makes the assumption that: 1) there is a need to systematically consider and explore FAILURE in its various parameters (definitions, characteristics, forms, shapes, potencies, densities, directions, tempos, levels, phases, meanings, and adhesiveness), sources, and "demands" in the broad area of substance use intervention; 2) we can learn from failure (categorizing its processes and outcomes, selecting foci for intervention, and failure's "veracity," status, transmittability and potential/actual usability over time); and 3) we should continue to repeat this process until there is little need to do so. As times and definitions change, there will never be an end to failure or the need to learn from failure. Failure is considered as a value, and having value, on a multidimensional, dynamic gradient (minimal to maximal), being describable, discernable, catagorizable, understandable, while being-culture-site-ideologically bound/influenced. Exploring FAILURE offers us-in our various substance use intervention roles-the opportunity to learn from what we have done and to more appropiately plan, implement, and assess what we may want and/or need to know and to do. Examples are given of ongoing sources of built-in substance use intervention failure.

Conventional and fast spin-echo MR imaging: minimizing echo time.

Magnetic resonance imaging is frequently complicated by the presence of motion and susceptibility gradients. Also, some biologic tissues have short T2s. These problems are particularly troublesome in fast spin-echo (FSE) imaging, in which T2 decay and motion between echoes result in image blurring and ghost artifacts. The authors reduced TE in conventional spin-echo (SE) imaging to 5 msec and echo spacing (E-space) in FSE imaging to 6 msec. All magnetic gradients (except readout) were kept at a maximum, with data sampling as fast as 125 kHz and only ramp waveforms used. Truncated sinc radio-frequency pulses and asymmetric echo sampling were also used in SE imaging. Short TE (5.8 msec) SE images of the upper abdomen were compared with conventional SE images (TE = 11 msec). Also, FSE images with short E-space were compared with conventional FSE images in multiple body sites. Short TE significantly improved the liver-spleen contrast-to-total noise ratio (C/N) (7.9 vs 4.1, n = 9, P < .01) on T1-weighted SE images, reduced the intensity of ghost artifacts (by 34%, P < .02), and increased the number of available imaging planes by 30%. It also improved delineation of cranial nerves and reduced susceptibility artifacts. On short E-space FSE images, spine, lung, upper abdomen, and musculoskeletal tissues appeared crisper and measured spleen-liver C/N increased significantly (6.9 vs 4.0, n = 12, P < .01). The delineation of tissues with short T2 (eg, cartilage) and motion artifact suppression were also improved. Short TE methods can improve image quality in both SE and FSE imaging and merit further clinical evaluation.

Based on partial RF echo planar principles, Fast Spin Echo techniques (FSE) were implemented on high field systems. These methods produce image quality and contrast which resemble to conventional spin echo (SE) techniques. By reducing acquisition times by factors between 1.4 and 16 over SE methods, FSE allows for several imaging options usually prohibitive with conventional spin echo (SE) sequences. These include fast scans (especially breath-hold acquisitions); improved T2 contrast with longer TR intervals; increased spatial resolution with the use of larger image matrices and/or smaller fields of view; and 3D volume imaging with a 3D multislab FSE technique. Contrast features of FSE techniques are directly comparable to those of multiple echo SE sequences using the same echo spacing than FSE methods. However, essential contrast differences existing between the FSE sequences and their routine asymmetric dual SE counterpart can be identified. Decreased magnetic susceptibility effects and increased fat signal present within T2 weighted images compared to conventional dual SE images are due to the use of shorter echo spacings employed in FSE sequences. Off-resonance irradiation inherent to the use of a large number of radio frequency pulses in shown to results in dramatic magnetization contrast transfer effects in FSE images acquired in a multislice mode.

First principles of fast spin echo.

Fast spin echo (FSE), a variant of the rapid acquisition with refocused echoes pulse sequence, is now being widely considered as an alternative to conventional spin echo for proton density and T2-weighted imaging. Although the medical experience with this sequence is relatively limited, relevant aspects of the technique have been well understood in the context of spectroscopic applications for many years. This article attempts to portray the subject in an appropriate historical context. Such a viewpoint promotes a deeper understanding of the artifacts, determinants of contrast, and future evolution of FSE. Hopefully, this may not only be of benefit in the design of optimal clinical imaging protocols for current state of the art but may also be of use in fashioning the criteria by which new developments in this field may be judged.

Treating the drug user: considering the "demands" of therapeutic technologies and their implications for treatment planning, implementation, and outcome.

Continued confusion regarding the actual and potential interface between technical issues (techniques/therapies) and ideological-theoretical considerations (treatment as a planned change process) results in built-in failure in the treatment of drug users. Only a limited number of currently available "therapies" are generally used for planned treatment intervention or for institutionalized reflexive reactions. Limited consideration has been given to the planning and implementation "demands" of a selected number of critical variables which affect the "therapies" currently in use and/or which can be chosen to be used. This note is designed as a catalytic cognitive resource to facilitate changing this situation by exploring some of the factors associated with this self-defeating, self-fulfilling prophecy.
