An Interdisciplinary Approach to Treating Severe Behavior in a Juvenile Justice Facility: Teaching Behavioral Self-Management via Telehealth

Adolescents living in residential juvenile justice facilities often receive mental health services during their stay to address committed offenses, yet some display challenging behavior during moments of conflict within the facility. These challenging behaviors could result in risk of harm to self or others, or the individual may experience punishment from facility staff. The purpose of this study was to explore the effects of an additive voluntary focused intervention for individuals who continued to display challenging behavior despite participation in "treatment as usual" in a juvenile justice facility. We implemented a self-management intervention, supported through interprofessional collaboration, via telehealth with four male adolescents. Using Behavior Skills Training, we taught participants to self-monitor precursors for challenging behavior and identify an alternative behavior to engage in to prevent overt challenging behavior events. Alternative behaviors were responses incompatible with the challenging behavior, or served as a rule to prompt self-management of further behavior. Results show all four participants increased their selection of alternative behaviors when presented with an evocative situation and a precursor for a severe behavior event during simulations. In addition, three participants stated they would use alternative behaviors across precursors not presented during teaching; however, two participants required booster sessions to maintain appropriate responding during simulations. Outside of simulated sessions, facility staff reported modest decreases in participants' challenging behavior during and after the intervention.

A Pilot Study Exploring Social Validity Ratings of Social Profiles for College Students

Nuhu and Rapp identified three profiles undergraduates displayed during social interactions. We evaluated the social validity of these three profiles in two studies. In Study 1 we presented video exemplars of speakers representing each profile to undergraduate participants and asked them to rate the speaker in respect to various statements. Results showed that one profile was rated significantly different than the other two profiles on all but one statement. In Study 2 we further evaluated the role of eye contact in the profile that participants rated differently in Study 1. Results from Study 2 showed that a speaker engaging in low eye contact was rated lower than a speaker engaging in either a validated or high level of eye contact. Likewise, participants with self-reported high social competency provided more negative ratings of a speaker who displayed low eye contact than participants with self-reported Moderate and Low social competency.

Eight Months of Telehealth for a State-Funded Project in Foster Care and Related Services: Progress Made and Lessons Learned

In response to the COVID-19 pandemic, many behavior analysts and other health professionals modified their services for delivery via telehealth modalities. The transition to telehealth is especially important for providers working with foster youth who exhibit challenging behavior because these youth often move to another placement due to such behaviors. The primary objective of this article was to evaluate the extent to which service indicators for a state-funded team working with foster youth changed after the service delivery model changed from in-person to telehealth services. In particular, we evaluated changes in monthly count of client contacts, appointments, intakes, closed cases, and medication reviews. The secondary objective was to outline potential benefits and environmental barriers encountered by the team and to integrate our findings with the literature on behavior-analytic services provided via telehealth. Overall, results show that we maintained service quality with a broad range of behavioral interventions and increased overall client appointments. Given these outcomes, our team may continue to provide behavioral services via telehealth after the COVID-19 pandemic.

Epidemiologic evaluation of Nhanes for environmental Factors and periodontal disease

Periodontitis is a chronic inflammation that destroys periodontal tissues caused by the accumulation of bacterial biofilms that can be affected by environmental factors. This report describes an association study to evaluate the relationship of environmental factors to the expression of periodontitis using the National Health and Nutrition Examination Study (NHANES) from 1999–2004. A wide range of environmental variables (156) were assessed in patients categorized for periodontitis (n = 8884). Multiple statistical approaches were used to explore this dataset and identify environmental variable patterns that enhanced or lowered the prevalence of periodontitis. Our findings indicate an array of environmental variables were different in periodontitis in smokers, former smokers, or non-smokers, with a subset of specific environmental variables identified in each population subset. Discriminating environmental factors included blood levels of lead, phthalates, selected nutrients, and PCBs. Importantly, these factors were found to be coupled with more classical risk factors (i.e. age, gender, race/ethnicity) to create a model that indicated an increased disease prevalence of 2–4 fold across the sample population. Targeted environmental factors are statistically associated with the prevalence of periodontitis. Existing evidence suggests that these may contribute to altered gene expression and biologic processes that enhance inflammatory tissue destruction.

Using Social Media to Reduce Multiple Risk Factors for CRC in Rural Appalachians: #CRCFREE

Purpose: To examine the efficacy, acceptability, feasibility, and applicability of a Facebook (FB) intervention designed to reduce multiple colorectal cancer (CRC) risk factors in older adults residing in rural Appalachian Kentucky. Methods: We piloted a 12 week FB intervention culturally tailored for older adults residing in rural Eastern Kentucky to impact CRC risk factors, including: nutrition, physical activity, and screening. Participants were aged 50+, had internet access, and were at risk for CRC. During the 12 week study, the participants received three daily posts via secret FB group regarding CRC risk factors. Demographics, dietary measures, body mass index (BMI), and CRC screening were assessed at baseline and post intervention. FB engagement and physical activity were tracked throughout the intervention. Dietary measures included the Healthy Eating Index (HEI) and Dietary Inflammatory Index (DII). Physical activity was tracked using Fitbits. Post-intervention focus group interviews were conducted to assess feasibility and acceptability. Results: Participants (n = 57) were Caucasian, aged 58 ± 6 years, predominately female (67%), and the majority reported at least a high school education (77%). Post intervention, participants experienced significant increase in HEI scores (49.94 ± 9.84 vs. 58.60 ± 12.06, P = < 0.01). DII scores significantly decreased (2.44 ±1.12 vs. 1.60 ± 1.63, P = 0.003). There was no significant change in physical activity, BMI, or screening status. Participants, on average, viewed more than half of the posts. Focus group participants found FB posts to be useful and motivating. They reported that FB posts were educational and motivational. Conclusion: This pilot study shows promising preliminary data to support using a FB intervention in rural Appalachian older adults to decrease CRC risks. Participants were receptive to FB intervention, and FB provides a unique and accessible method for health promotion in hard to reach populations.

Hospice care in Medicare patients with primary liver cancer: the impact on resource utilisation and mortality

BACKGROUND

Few studies have assessed the impact of hospice care in patients with primary liver cancer.

AIM

To examine the determinants of hospice care and its effects on resource utilisation and survival among Medicare beneficiaries with primary liver cancer.

METHODS

We utilised the Surveillance, Epidemiology and End result Registry (SEER) database from 2002 to 2009 for this cross-sectional study. A total of 3385 patients with primary liver cancer were included. We used logistic regression to discern variables associated with hospice and Cox proportional hazards models to evaluate one-year mortality risk.

RESULTS

Compared to patients who enrolled in a hospice, those patients who did not, were younger, non-White and sicker (P < .05 for all). Half of all patients with primary liver cancer died within six months of diagnosis, and one-year mortality was similar in both groups (P = .413). After adjusting for baseline characteristics [age at diagnosis, race, disease severity, tumour stage and treatment], shorter time to hospice care was associated with reduced mortality (HR per day: 0.99 [95% CI, 0.98-0.99]). Older age, decompensated cirrhosis and advanced tumours stage were associated with decreased time to hospice, while Asian/Pacific Islander race and history of radiosurgery were associated with increased time to hospice (all P < .05). Hospitalisations were more costly for those who never enrolled in a hospice compared to hospice enrollees (median $31 607 [$18 394-$54 254] vs $22 316 [$13 741-$36 170], P < .0001).

CONCLUSIONS

Hospice enrolment of patients with primary liver cancer provides survival and resource utilisation benefits. Some clinical and demographic factors may represent barriers to hospice enrolment. Further studies are needed to fully understand these barriers in patients with primary liver cancer.

The evaluation of an approach to reflective learning in the undergraduate dental curriculum

Students in higher education are being encouraged to become active, independent and life-long learners. The use of progress files has been endorsed to encourage this approach. A portfolio intended to fulfil the role of a progress file and to promote student-centred learning and reflection was introduced as a central component of the revised undergraduate degree at the Glasgow Dental School in 2004. This article evaluates its role in promoting reflection. Students following the Bachelor of Dental Surgery (BDS) programme completed three written reflections per year using structured proformas, and discussed them with their mentor and mentoring group. Their views of the portfolio and of reflection were gathered using a five-point Likert scale. In BDS1 2004-5, 84% completed a questionnaire, as did 89% in BDS1 2005-6 and 99% in BDS2 2005-6. Most students did not enjoy reflecting (a finding commonly reported elsewhere) or feel that reflection identified their learning needs. It appears that students disliked writing reflections, rather than reflecting per se. In contrast, they took a positive view of mentor group discussions and of having a mentor, both essential components of the portfolio model described. Comparisons of BDS1 2004-5 and BDS2 2005-6 data suggest that students are becoming more comfortable with reflection. The data provide some limited encouragement that students are beginning to acquire the skills which will enable them to reflect purposefully in their professional lives, although it will be some years before this assertion can be substantiated.

Evolution of atherogenic diets in South Asian and Italian women after migration to a higher risk region

BACKGROUND

To identify differences in the evolution of the diets of South Asian and Italian migrants, a cross-sectional, multiethnic study was undertaken in Glasgow, Scotland.

METHODS

Five groups of women aged 20-42 years comprising general population (n = 35), South Asian migrants (n = 35) British-born controls (n = 37), Italian migrants (n = 30) and British-born (n = 38) participated in an interviewer administered structured questionnaire on issues relating to health, diet and food selection. Anthropometric measurements were made and subjects completed a 7-day weighed diet inventory.

RESULTS

Compared with the general population, dietary differences were greatest amongst first generation migrant groups. There were major differences between the two migrant groups. South Asian migrants tended to display a more atherogenic profile (fat 42.4% energy, saturated fat 15.0% energy, vitamin C 5.1 mg per 1000 kJ) than the general population (fat 39.1% energy, saturated fat 13.5% energy, vitamin C 6.8 mg per 1000 kJ), and Italian migrants (fat 35.7% energy, saturated fat 12.1% energy, vitamin C 10.9 mg per 1000 kJ). However, South Asian groups had higher intakes of polyunsaturated fatty acids which may be cardioprotective.

CONCLUSIONS

South Asian migrants to Scotland appear to develop adverse dietary elements in the first generation, which are modified in subsequent generations, whereas Italians' diets remain cardioprotective in the migrant generation but deteriorate in subsequent generations.

Ethnic differences in anthropometric and lifestyle measures related to coronary heart disease risk between South Asian, Italian and general-population British women living in the west of Scotland

AIMS

To compare anthropometric measurements and to define their behavioural associations in migrant and British-born South Asians (who have increased cardiovascular risk) or Italians (who have reduced cardiovascular risk), and in the general population of British women living in the west of Scotland.

STUDY DESIGN

Cross-sectional survey of women aged 20-42 y, selected mainly from birth registration data, which included 63 migrant South Asians, 56 British-born South Asians, 39 migrant Italians, 51 British-born Italians, and 50 subjects representative of the general population of women, all resident in the west of Scotland.

MEASUREMENTS

Height, weight, body mass index (BMI), and waist and hip circumferences.

RESULTS

With age adjustment, migrant South Asians (0.88) had greater waist-to-hip ratio than British-born South Asians (0.84; P<0.05), while there was no difference between migrant (0.81) and British-born (0.79) Italian groups. Both migrant (P<0.001) and British-born South Asian (P<0.05) groups had higher waist-to-hip ratio and were about 3 cm shorter than Italian groups and the general population. Neither weight nor BMI were different between ethnic groups. Waist and hip circumferences were not different between migrant and British-born ethnic minority groups. Migrant South Asians (86.8 cm) had significantly (P<0.05) larger waist circumference than the general population (78.6 cm). British-born Italian women (103.0 cm) had larger hip circumference than the general population of women (96.4 cm), while other groups had similar hip circumferences. Additional adjustments for physical activity, smoking, alcohol consumption and parity reduced the differences in anthropometric measurements: only waist-to-hip ratio of migrant South Asians remained significantly (P<0.01) higher than that of the general population women.

CONCLUSIONS

The adverse anthropometric indicators of cardiovascular risk in migrant South Asian women are substantially explained by their lifestyle factors and parity. British-born South Asian women are more similar to the general population women. Anthropometric differences between migrant or British-born Italians and the general population women are small.

A link between diabetes and atherosclerosis: Glucose regulates expression of CD36 at the level of translation

Both the risk and the rate of development of atherosclerosis are increased in diabetics, but the mechanisms involved are unknown. Here we report a glucose-mediated increase in CD36 mRNA translation efficiency that results in increased expression of the macrophage scavenger receptor CD36. Expression of CD36 was increased in endarterectomy lesions from patients with a history of hyperglycemia. Macrophages that were differentiated from human peripheral blood monocytes in the presence of high glucose concentrations showed increased expression of cell-surface CD36 secondary to an increase in translational efficiency of CD36 mRNA. We obtained similar data from primary cells isolated from human vascular lesions, and we found that glucose sensitivity is a function of ribosomal reinitiation following translation of an upstream open reading frame (uORF). Increased translation of macrophage CD36 transcript under high glucose conditions provides a mechanism for accelerated atherosclerosis in diabetics.

Elevated Egr-1 in human atherosclerotic cells transcriptionally represses the transforming growth factor-beta type II receptor

Atherosclerotic lesions may progress due to a "failure to die" by vascular repair cells. Egr-1, a zinc finger transcription factor, is elevated more than 5-fold in human carotid lesions relative to the adjacent tunica media. Lesion cells in vitro also express 2-3-fold higher Egr-1 mRNA and protein levels but express much lower levels of the transforming growth factor-beta (TGF-beta) Type II receptor (TbetaR-2) and are functionally resistant to the antiproliferative effects of TGF-beta. Lesion cells fail to express a TbetaR-2 promoter/chloramphenicol acetyltransferase (CAT) construct but overexpress an Egr-1-inducible platelet-derived growth factor-A promoter/CAT construct. Transfection of Egr-1 cDNA represses TbetaR-2/CAT constructs but induces PDGF-A/CAT. Egr-1 transfection reduces the levels of TbetaR-2 and confers resistance to the antiproliferative effect of TGF-beta1. Egr-1 can interact directly with both the -143 Sp1 site and the positive regulatory element 2 (PRE2) (ERT/ets) region of the TbetaR-2 promoter. Thus, although activating a family of stress-responsive genes, Egr-1 also transcriptionally represses one of the major inhibitory pathways that restrains vascular repair.

High-level expression of Egr-1 and Egr-1-inducible genes in mouse and human atherosclerosis

To understand the mRNA transcript profile in the human atherosclerotic lesion, RNA was prepared from the fibrous cap versus adjacent media of 13 patients undergoing carotid endarterectomy. cDNA expression arrays bearing 588 known genes indicated that lesions express unexpectedly high levels of the early growth response gene, Egr-1 (NGFI-A), a zinc-finger transcription factor that modulates a cluster of stress-responsive genes including PDGF and TGF-beta. Expression of Egr-1 was an average of 5-fold higher in the lesion than in the adjacent media, a result confirmed by RT-PCR, and many Egr-1-inducible genes were also strongly elevated in the lesion. Time-course analyses revealed that Egr-1 was not induced ex vivo. Immunocytochemistry indicated that Egr-1 was expressed prominently in the smooth muscle-actin positive cells, particularly in areas of macrophage infiltration, and in other cell types, including endothelial cells. Induction of atherosclerosis in LDL receptor-null mice by feeding them a high-fat diet resulted in a progressive increase in Egr-1 expression in the aorta. Thus, induction of Egr-1 by atherogenic factors may be a key step in coordinating the cellular events that result in vascular lesions.

Preparative resolution of enantiomers of prostaglandin precursors by liquid chromatography on a chiral stationary phase

Preparative liquid chromatographic methods were developed for the chiral resolution of two different cyclopentenone precursors of a synthetic prostaglandin. Various solvent combinations of alcohols and alkanes were investigated to determine the method which has the greatest throughput. The effect of particle size on the chiral resolution was also investigated. In addition, the preparative system was automated to allow for unattended operation for up to 10 h.

Heroin vs morphine for cancer pain?

Narcotic analgesics are the mainstay of pain control in patients with cancer. A controversy has been raging in the United States and Canada as to the legalization of heroin. We have reviewed the literature in order to determine the relative efficacy of heroin and morphine in cancer pain. We applied the following methodologic criteria: Was the assignment of patients to the different opiates randomized? Were all clinically relevant outcomes reported? Were the patients recognizable? Were both clinical and statistical significance considered? Was the opiate regimen feasible in routine clinical practice? Were all patients who entered the study accounted for at its conclusion? Two trials satisfied our first standard. The first, a double-blind cross-over trial, failed to meet standard 4 (the negative conclusion may represent a type 2 error) and only 21% of patients completed both treatment periods. The second study, which compared intramuscular heroin and morphine among patients with postoperative pain, failed to meet standards 3 (patients not described in sufficient detail and only tangentially related to chronic cancer pain) and 4 (type 2 error). Thus the relative efficacy of heroin and morphine in the relief of chronic cancer pain remains unknown. Randomized trials that meet all six methodologic standards must therefore be carried out for this controversy to be resolved.

Controlled trial of adjuvant chemotherapy with cyclophosphamide, methotrexate, and fluorouracil for breast cancer

327 patients with cancer of the breast and involvement of axillary lymph nodes were randomised, after total mastectomy and axillary clearance, to receive either no additional treatment or oral cyclophosphamide 80 mg/m2 on days 1-14, intravenous methotrexate 32 mg/m2 on days 1 and 8, and intravenous fluorouracil 480 mg/m2 on days 1 and 8 (CMF), which was repeated every 28 days for twelve cycles. There was a significantly longer relapse-free survival (RFS) in patients treated with CMF. A prolonged RFS was seen in premenopausal patients, those with 1-3 nodes involved, and those with 4 or more nodes involved, but a similar trend in postmenopausal patients failed to reach statistical significance. RFS was greater in patients with CMF-induced amenorrhoea than in controls and in treated patients whose primary tumour contained progesterone receptors. Dose of chemotherapy did not have a significant effect on RFS. Survival was not influenced by treatment.

Controlled trial of adjuvant chemotherapy with melphalan for breast cancer

370 patients who had carcinoma of the breast with involved axillary lymph-nodes were randomised after total mastectomy and axillary clearance to receive either no additional treatment or melphalan 6 mg/m2 daily for 5 days every 6 weeks for sixteen cycles. There was a trend towards longer relapse-free survival (RFS) in patients treated with melphalan, but this was not significant either in the whole series or in sub-groups according to menopausal status or extent of nodal involvement. In patients receiving melphalan RFS was not significantly affected by either the occurrence of amenorrhoea or the dosage of melphalan received. Overall survival did not differ significantly between the two groups. The results of this trial suggest that there is no place for the use of melphalan as adjuvant therapy in the management of early breast cancer.

A comparison of ticlopidine and heparin on hemodialysis in dogs

The efficacies of low-dose heparin and low-dose heparin plus ticlopidine as anticoagulants during hemodialysis in acutely uremic dogs were compared and evaluated. Heparin was administered as a bolus at a dose of 100 U/kg. In preliminary experiments it was determined that dogs dialyzed with ticlopidine alone demonstrated gross clotting of the artificial kidney within 2.5 hr. Ticlopidine was administered by gavage at a dose of 50 mg/kg/day starting 72 hr prior to hemodialysis and continuing throughout the period of hemodialysis (4 days). Each dog was dialyzed four times with either heparin alone or heparin plus ticlopidine. Each hemodialysis lasted 3.5 hr. Parameters followed included dialysis clearance of urea and creatinine, ultrafiltration rate, residual blood volume, gross clotting episodes, platelet count, and levels of fibrinogen and thromboxane B2. A lesser degree of hemodialysis-associated thrombocytopenia, a lower residual blood volume, fewer episodes of gross clotting, no reduction in fibrinogen levels, and no increase in thromboxane B2 levels were observed in the heparin plus ticlopidine group as compared to the heparin group alone. Although ticlopidine at the dosage employed should not be used as the sole anticoagulant for hemodialysis, it may be useful when added to low-dose heparin. The salutary effects demonstrated in this study suggest clinical benefits of the combination.

A comparison of prostacyclin and heparin on hemodialyses in dogs

A comparison of the efficacy of prostacyclin and heparin as anticoagulants during hemodialysis in uremic dogs was evaluated. Prostacyclin was infused continuously into the arterial limb of the dialyzer (100 ng/kg/min) while heparin was administered as a 5000 unit bolus at the beginning of dialysis. Prostacyclin and heparin were alternated and a total of 4 dialyses/dog were performed. Parameters followed to assess the efficacy of dialyses included: dialysance (ml/min) of urea, creatinine, ultrafiltration rate (ml/hr), residual volume and platelet count (% of baseline). A lesser degree of hemodialysis associated thrombocytopenia, and a higher ultrafiltration rate were observed with prostacyclin. These studies demonstrate that prostacyclin can be used alone as an anticoagulant in a uremic dog model, and in contrast to heparin it maintains the platelet count and improves the ultrafiltration rate during hemodialysis.

Serum glycoprotein hormone alpha subunit, hormone receptors and disease stage in patients with breast cancer

The concentration of the common alpha subunit of the glycoprotein hormones was high in the serum of 21/56 (38%) of premenopausal patients and 22/106 (21%) of postmenopausal patients with primary breast cancer, at the time of presentation. 7/59 (12%) of patients with benign disease also had high alpha subunit levels. Tumour cytosol oestrogen and progesterone receptor status was determined in 80% of the patients with cancer, and there was a trend towards higher alpha levels in patients without receptors, but this was not statistically significant. In the premenopausal patients with cancer there was a significant correlation between alpha subunit level and disease stage, R = 0.47, P = 0.0001, but not in the postmenopausal patients. In view of the correlation with disease stage, high levels of alpha subunit in premenopausal patients with breast cancer at presentation with the primary tumour may indicate poor prognosis.

Chemotherapy in the management of invasive bladder cancer. A review

In this review of the management of invasive carcinoma of the bladder the results of primary and systemic therapies are evaluated in the light of the natural history of the disease. The clinical and pathological causes of treatment failure are assessed in an attempt to identify new approaches that may be used in the future management of patients with bladder cancer. To improve survival in this disease requires different approaches to both the control of local disease and the early control of metastatic disease.

Adjuvant chemotherapy: an approach to the management of malignant disease

The definition of the roles of surgery and radiation therapy in controlling local malignant disease has become much clearer in the past two decades. Nonetheless, most patients who die of their malignancy do so from metastatic disease. With the advent of effective combination chemotherapy for many patients with advanced malignant disease, the employment of systemic treatment at an earlier stage has become a clinical possibility. Important advances in the systemic control of a number of malignancies have been described. These are examples of a few of the presently ongoing trials (Salmon and Jones, 1977). For the merits and demerits of prophylactic systemic treatments to be accurately determined in malignant disease, it is important that the future role of adjuvant chemotherapy in man be evaluated only in the context of carefully controlled clinical trials. The fact that adjuvant therapy is effective in prolonging survival in some malignant diseases is established; its role in many of the commoner malignant diseases awaits more complete evaluation.

Cell cycle changes in transformed cells growing under serum-free conditions

Polyoma transformed hamster cells (PyBHK) and SV40 transformed mouse cells (SV3T3) were transferred in culture using crystalline trypsin followed by neutralisation with soybean trypsin inhibitor. Such cells were able to proliferate freely in defined medium without any serum supplement and without any intervening period of adaptation. However, growth rates were reduced under serum-free conditions. Re-establishment of rapid growth rates could be achieved by addition of serum, with the rate attained being proportional to the serum concentration. Irrespective of the prevailing rates of growth, percentages of cells synthesising DNA were the same. However, the rate at which DNA was being synthesised was found to change proportionately with the changes in overall growth rate.
