Study protocol testing toolkit versus usual care for implementation of screening, brief intervention, referral to treatment in hospitals: a phased cluster randomized approach.

BACKGROUND: Alarming rates of unhealthy alcohol, non-prescription drug, and tobacco use highlight the preventable health risks of substance abuse and the urgent need to activate clinicians to recognize and treat risky use. Screening, brief intervention, and referral to treatment (SBIRT) is an efficacious and effective processes to identify, reduce and prevent risky use of substances. This paper describes a study protocol testing implementation of a toolkit to enhance use of SBIRT in acute care settings to recognize and address patient risky alcohol, drug, and tobacco use. METHODS: This study uses a phased cluster randomized mixed method design to test nurse-led implementation of an SBIRT toolkit on one medical-surgical unit at 14 acute care hospitals (critical access, community and academic health centers). Medical surgical units will be randomly assigned to implement the SBIRT toolkit (engagement and communication, assessment, planning, training, and evaluation tools) or a wait-list usual care control group that begins implementation 6 months later. Primary endpoints are documentation of SBIRT delivery in randomly selected electronic medical records at baseline, 6 months and 12 months after group 1 implementation (61 records per unit per time period, N = 2562). Two surveys will be administered to unit nurses: smoking cessation activities will be assessed at baseline and SBIRT use will be assessed on randomly-selected days after implementation. In addition, site coordinators will complete a baseline capacity assessment, an implementation fidelity survey post-implementation, and a structured interview at the end of the study. Multilevel mixed-effects effects logistic and linear models will be used to analyze use of SBIRT and cost outcomes. DISCUSSION: This study will guide subsequent SBIRT implementation, dissemination, and spread across rural, community and urban healthcare systems throughout the state and beyond. The long-term objective is to activate clinicians to recognize, intervene and refer people with risky substance use to improve health and decrease substance use disorders.

Electroconvulsive Therapy for Super Refractory Status Epilepticus.

OBJECTIVES: Super refractory status epilepticus (SRSE) is a stage beyond refractory status that requires general anesthesia as management. Electroconvulsive therapy (ECT) is recommended only as a potential treatment option beyond general anesthesia and after all other options have been exhausted. Its effect on aborting status has been minimally researched. We present the largest case series to our knowledge exploring the effect of ECT on SRSE. METHODS: Eight adults hospitalized for SRSE received ECT in an attempt to abort status after other treatment modalities were exhausted. Electroconvulsive therapy consisted of a 504-mC (≈99.4 J) stimulus delivered bifrontotemporally with a constant 0.5-millisecond pulse width. Seizure activity during ECT was monitored visually and correlated to the single-channel recording provided by the apparatus. RESULTS: There was neurotelemetry or clinical evidence of improvement within 24 hours after the full course of ECT treatment in 5 (63%) of the 8 cases. Cases that improved were given an average of 7.8 total ECT stimulations, eliciting an average of 4.2 total seizures. CONCLUSIONS: Although it is difficult to determine the exact role of ECT in the improvement of 63% of our cases, we present a series of patients for whom pharmacotherapy, ketogenic diet, and general anesthesia otherwise did not produce an appreciable effect on status prior to implementation of ECT. These findings suggest that cases of SRSE may benefit from ECT administration.

The most effective strategy for recruiting a pregnancy cohort: a tale of two cities.

BACKGROUND: Pregnant women were recruited into the Alberta Pregnancy Outcomes and Nutrition (APrON) study in two cities in Alberta, Calgary and Edmonton. In Calgary, a larger proportion of women obtain obstetrical care from family physicians than from obstetricians; otherwise the cities have similar characteristics. Despite similarities of the cities, the recruitment success was very different. The purpose of this paper is to describe recruitment strategies, determine which were most successful and discuss reasons for the different success rates between the two cities. METHODS: Recruitment methods in both cities involved approaching pregnant women (< 27 weeks gestation) through the waiting rooms of physician offices, distributing posters and pamphlets, word of mouth, media, and the Internet. RESULTS: Between May 2009 and November 2010, 1,200 participants were recruited, 86% (1,028/1,200) from Calgary and 14% (172/1,200) from Edmonton, two cities with similar demographics. The most effective strategy overall involved face-to-face recruitment through clinics in physician and ultrasound offices with access to a large volume of women in early pregnancy. This method was most economical when clinic staff received an honorarium to discuss the study with patients and forward contact information to the research team. CONCLUSION: Recruiting a pregnancy cohort face-to-face through physician offices was the most effective method in both cities and a new critically important finding is that employing this method is only feasible in large volume maternity clinics. The proportion of family physicians providing antenatal and post-natal care may impact recruitment success and should be studied further.

A local moment approach to the degenerate Anderson impurity model.

The local moment approach is extended to the orbitally degenerate (SU(2N)) Anderson impurity model (AIM). Single-particle dynamics are obtained over the full range of energy scales, focusing on particle-hole symmetry in the strongly-correlated regime where the onsite Coulomb interaction leads to many-body Kondo physics with entangled spin and orbital degrees of freedom. The approach captures many-body broadening of the Hubbard satellites and recovers the correct exponential vanishing of the Kondo scale for all N, and its universal scaling spectra are found to be in very good agreement with numerical renormalization group (NRG) results. In particular the high-frequency logarithmic decays of the scaling spectra, obtained here in closed form for arbitrary N, coincide essentially perfectly with available numerics from the NRG. A particular case of an anisotropic Coulomb interaction, in which the model represents a system of N 'capacitively coupled' SU(2) AIMs, is also discussed. Here the model is generally characterized by two low-energy scales, the crossover between which is seen directly in its dynamics.

[Not Available]. / La santé en situation linguistique minoritaire.

Literature suggests the hypothesis that there is a health differential for minority French-speaking groups in Canada. The effect of minority on perceived health has been measured using the 2001 and 2003 Canadian Community Health Survey (CCHS). The sequential multivariate logistic regression analysis shows that the minority French-speaking groups - men and women - are more likely to declare a poorer health condition than the majority English-speaking groups. Contrary to women, this disparity among men groups remains significant even when adjustments are made according to some of the key health determinants. The study shows that the action of health determinants can be modulated by the minority/majority ratio. The identified disparities remind the need for a reflection on linguistic healthcare access policies.

The prevalence and molecular basis of hemoglobinopathies in Cambodia.

Blood counts, hemoglobin (Hb) high performance liquid chromatography (HPLC), and DNA analyses were performed on 260 children, aged 5 months to 16 years, at Siem Reap to assess the prevalence of thalassemia and other hemoglobinopathies in regional Cambodia. Hemoglobinopathies were present in 134 children (51.5%) with 20 abnormal genotypes identified. alpha-Thalassemia (thal) (35.4%) was the most prevalent disorder and the -alpha3.7 gene deletion was the most common alpha-globin gene abnormality. The - -SEA deletion and nondeletional forms of alpha-thal, Hb Constant Spring [Hb CS, alpha142, Term-->Gln, TAA-->CAA (alpha2)], Hb Paksé [alpha142, Term-->Tyr, TAA-->TAT (alpha2)] and triplicated alpha genes, were also present but at low frequencies. Hb E [beta26(B8)Glu-->Lys, GAG-->AAG] (28.8%) was the most common beta-globin gene abnormality, whilst beta-thal was only detected in two children (0.8% of cases). Although hemoglobinopathies were common, the majority of abnormalities detected (heterozygous -alpha3.7 and Hb E) were not clinically significant. On the basis of these findings, and with the majority of abnormalities being mild, it seems improbable that thalassemia represents a major health burden in this region of Cambodia.

Social capital, health, and Francophone minorities.

The goal of this article is to outline the analytical perspectives of the concept of social capital regarding health and health management. Social capital, as defined in terms of social networks and resources, has a positive impact on a number of areas, notably the health, well-being, and social and economic development of communities. It is also a useful tool for implementing social policy, especially for marginal populations, the elderly, social assistance payments, etc. An action strategy based on the support and development of networks is the key to achieving the social development, health, and well-being of populations. The social ties promoted by these networks provide people with social, cognitive, and emotional support. This has a direct impact on their self-esteem and sense of personal achievement. They also facilitate access to social resources, including social advancement opportunities. In this paper, we examine the vitality, determinants of health, and health management of Canada's minority Francophone communities.

Hemoglobinopathies in the Christmas Island population.

Christmas Island is a remote Australian territory 2,400 km north of Perth. Health care is administered from Perth. The population is predominantly Chinese, with some Malay, Indian and European. As hemoglobinopathies are known to be common amongst these ethnic groups, a study was performed to determine their prevalence and significance in the Christmas Island population. Three-hundred and sixty-four individuals (adults and children) were tested. All subjects were assessed by full blood count, alpha-globin multiplex polymerase chain reaction (PCR) and PCR testing for Hb Constant Spring [alpha142, Term-->Gln, TAA-->CAA (alpha2)]. Microcytic patients (MCV <80 fL) were further investigated by high performance liquid chromatography (HPLC) and serum ferritin was determined. Where present, beta-thalassemia (thal) mutations were characterised by PCR. Thirty-four subjects (9.3%) were microcytic and of these five were iron deficient. The remainder were heterozygous for a hemoglobinopathy, giving a 9.1% incidence of hemoglobinopathies in Christmas Islanders. alpha-Thalassemia was identified in 23 subjects, seven of whom were heterozygous for alpha(-3.7); the remaining 16 were heterozygous for the - -SEA deletion. One case of heterozygous deltabeta-thal and one case of heterozygous Hb E [beta26(B8)Glu-->Lys] was detected. Of the eight subjects heterozygous for beta-thal, at least five mutations are represented, indicating a diverse and heterogeneous origin for this population.
