Racial and Ethnic Differences in Psychotropic Prescription Receipt Among Pediatric Patients Enrolled in North Carolina Medicaid.

OBJECTIVE: The authors aimed to examine racial-ethnic differences in filled psychotropic prescriptions among a pediatric Medicaid population. METHODS: This retrospective cohort study included patients ages 0-21 with at least one North Carolina Medicaid claim from October 1, 2017, through September 30, 2018 (N=983,886). The primary outcome was a filled psychotropic prescription. Separate multivariable modified Poisson regression models generated adjusted risk ratios (ARRs) and 95% confidence intervals (CIs), adjusted for patient demographic characteristics. RESULTS: Black and Hispanic patients were significantly less likely to receive any filled psychotropic prescription (ARR=0.61, 95% CI=0.60-0.62; ARR=0.29, 95% CI=0.28-0.29, respectively) compared with White and non-Hispanic patients. Furthermore, Black and Hispanic patients were less likely to receive filled prescriptions in the four included drug classes compared with White and non-Hispanic patients. CONCLUSIONS: Future studies should focus on understanding the factors contributing to racial and ethnic differences among pediatric patients receiving filled psychotropic prescriptions.

Use of North Carolina Medicaid Collaborative Care Billing Codes After Statewide Approval for Reimbursement.

Effective October 2018, North Carolina Medicaid approved reimbursement for collaborative care model (CoCM) billing codes. From October 2018 through December 2019, only 915 of the estimated two million eligible Medicaid beneficiaries had at least one CoCM claim, and the median number of claims per patient was two. Availability of reimbursement for CoCM Medicaid billing codes in North Carolina did not immediately result in robust utilization of CoCM. Furthermore, the low median number of claims per patient suggests lack of fidelity to CoCM. A better understanding of barriers to CoCM implementation is necessary to expand utilization of this evidence-based model.

Brief Report: Classifying Rates of Students with Autism and Intellectual Disability in North Carolina: Roles of Race and Economic Disadvantage.

We examined special education classifications among students aged 3-21 in North Carolina public schools, highlighting autism spectrum disorder (ASD) and intellectual disability (ID). Results revealed variability by county in ASD and ID prevalence, and in county-level ratios of ID vs. ASD classifications. Sociodemographic characteristics predicted proportion of ASD or ID within a county; correlations showed an association between race and ID, but not ASD. County's median household income predicted proportion of students classified as ASD and ID (opposite directions), controlling for number of students and gender. Variability was unlikely related to biological incidence, and more likely related to district/school practices, or differences in resources. Disparities warrant further examination to ensure that North Carolina's youth with disabilities access necessary, appropriate resources.

Stand When You Can: development and pilot testing of an intervention to reduce sedentary time in assisted living.

BACKGROUND: Prolonged daily sedentary time is associated with increased risk of cardiometabolic diseases, impaired physical function, and mortality. Older adults are more sedentary than any other age group and those in assisted living residences accumulate more sedentary time as they often have little need to engage in light-intensity or standing activities such as cleaning or meal preparation. This "low movement" environment can hasten functional decline. Thus, the purpose of this study was to develop a multi-level intervention to reduce and interrupt sedentary time within assisted living residences and conduct a pilot study to determine if the intervention is feasible and if further testing is warranted. METHODS: "Stand When You Can" (SWYC) was developed using a Social Ecological framework based on a review of literature and consultation with residents and staff at assisted living residences. After development, a six-week pilot study was conducted in two different residences with 10 older adults (82.2 ± 8.7 years). Before and after the 6 weeks, ActivPAL™ inclinometers were used to measure daily movement behaviours and self-report questionnaires assessed time spent in different sedentary behaviours and quality of life. Physical function was assessed using the Short Physical Performance Battery. Paired sample t-tests examined pre-post differences for pooled data and individual sites. At the end of the pilot study, feedback on the intervention was gathered from both residents and staff to examine feasibility. RESULTS: There was a trend towards a decrease in self-reported sitting time (142 min/day; p = 0.09), although device-measured sedentary time did not change significantly. Participants with lower physical function at baseline showed clinically meaningful improvements in physical function after the 6 weeks (p = 0.04, Cohen's d = 0.89). There was no change in quality of life. Residents and staff reported that the intervention strategies were acceptable and practical. CONCLUSION: This study suggests that a multi-level intervention for reducing prolonged sedentary time is feasible for implementation at assisted living residences. The intervention could potentially help delay functional decline among older adults when they transition to a supportive living environment. Longer and larger trials to test the efficacy of SWYC are necessary. TRIAL REGISTRATION: Name of Clinical Trial Registry: clinicaltrials.gov Trial Registration number: NCT04458896 .

De novo CACNA1D Ca2+ channelopathies: clinical phenotypes and molecular mechanism.

The identification of rare disease-causing variants in humans by large-scale next-generation sequencing (NGS) studies has also provided us with new insights into the pathophysiological role of de novo missense variants in the CACNA1D gene that encodes the pore-forming α1-subunit of voltage-gated Cav1.3 L-type Ca2+ channels. These CACNA1D variants have been identified somatically in aldosterone-producing adenomas as well as germline in patients with neurodevelopmental and in some cases endocrine symptoms. In vitro studies in heterologous expression systems have revealed typical gating changes that indicate enhanced Ca2+ influx through Cav1.3 channels as the underlying disease-causing mechanism. Here we summarize the clinical findings of 12 well-characterized individuals with a total of 9 high-risk pathogenic CACNA1D variants. Moreover, we propose how information from somatic mutations in aldosterone-producing adenomas could be used to predict the potential pathogenicity of novel germline variants. Since these pathogenic de novo variants can cause a channel-gain-of function, we also discuss the use of L-type Ca2+ channel blockers as a potential therapeutic option.

Health care engagement behaviors of men who use performance- and image-enhancing drugs in Australia.

Background: Although people who inject performance- and image-enhancing drugs (PIEDs) report fewer unsafe injecting practices, stigma and discrimination may negatively impact their access to help and information. Engagement with health care services, compared with social networks (friends, relatives, and gym associates) and the Internet and media (steroid user forums, information sites, and magazines), may be important for harm minimization. Methods: A cross-sectional Internet or in-person survey of men who use PIEDs in Australia in 2014-2015 examined differences in sources for PIEDs, injecting equipment, and anabolic-androgenic steroids (AAS) information and factors associated with having periodical medical checks related to PIEDs issues using multivariate logistic regression. Results: In total, 267 men (mean age: 25 years, SD: 8.7 years; 246 of 267 [92%] reported recent AAS injection) were recruited. Most participants sourced injecting equipment from health professionals, PIEDs from their social networks, and AAS information from the Internet and media. Self-reported AAS knowledge was high and frequent. Higher income (adjusted odds ratio [AOR]: 2.04, 95% confidence interval [CI]: 1.03, 4.00), ≥2 different PIEDs used in addition to AAS (AOR: 1.94, 95% CI: 1.08, 3.49), and sourcing AAS information from health care professionals (AOR: 3.14, 95% CI: 1.81, 5.46) were independently associated with periodical medical checks. Participants nominated preference for improved health services through needle-syringe programs, primary care services, and peer educator support groups. Conclusion: Men who use PIEDs in Australia consider themselves well informed but tend to use Internet and media sources, providing potentially misleading or inaccurate information. Increasing trust between men who use PIEDs and health care providers may enable delivery of PIEDs-specific information to those at greatest need.

The effect of induction with propofol or ketamine and diazepam on quality of anaesthetic recovery in dogs.

OBJECTIVE: To evaluate the quality of recovery in dogs undergoing elective orthopaedic surgery induced with either propofol or a combination of ketamine and diazepam. MATERIALS AND METHODS: Sixty client-owned dogs undergoing single-limb elective orthopaedic procedures were enrolled. Dogs were randomly assigned to receive induction with propofol (4 mg/kg) (group P) or ketamine (5 mg/kg) with diazepam (0.25 mg/kg) (group KD) to which all scorers were blinded. The recovery monitoring period lasted for 1 hour following extubation. The recovery period was video-recorded for blinded scoring at a later time. Scoring for quality of recovery was carried out using three different systems (lower numbers=better quality): a simple descriptive scale (1 to 5), a visual analogue scale (0 to 10 cm) and a numeric rating scale (0 to 10). Videos were reviewed by three ACVAA board-certified anaesthesiologist raters. RESULTS: Five dogs were deemed to be ineligible. The mean (±SD) duration of anaesthesia was 260.4 ±57.84 minutes in group KD and 261.1 ±51.83 minutes in group P. There was no difference between groups for time to extubation, head lift or sternal recumbency. The number of dogs having a recovery that was scored overall as bad (mean simple descriptive scale > 4, mean visual analogue scale or numeric rating scale > 5) was not different between groups. Dogs in group KD had significantly lower scores than group P dogs (simple descriptive scale P=0.01, numeric rating scale P=0.03, visual analogue scale P=0.03). CLINICAL SIGNIFICANCE: Induction with ketamine and diazepam resulted in a smoother recovery from anaesthesia than induction with propofol.

Cannabis use in early adolescence is associated with higher negative schizotypy in females.

The current study examined the relationship between early onset cannabis use (before age 16) and different schizotypy dimensions, and whether gender moderates these associations. Participants were 162 cannabis users, aged 15-24 years, who completed an online assessment examining alcohol and other drug use, psychological distress, and schizotypy. Participants were divided according to whether or not they had started using cannabis before the age of 16 (early onset=47; later onset=115) and gender (males=66; females=96). The interaction between gender and onset group was significantly associated with the dimension of introvertive anhedonia. Follow-up analyses showed that early onset cannabis use was associated with higher levels of introvertive anhedonia in females only. The current findings suggest that gender is an important moderator in the association between early onset cannabis use, schizotypy, and possibly, psychosis risk.

Impact of Immunosuppression on the Metagenomic Composition of the Intestinal Microbiome: a Systems Biology Approach to Post-Transplant Diabetes.

Solid organ transplantation (SOT) outcomes have continued to improve, although long-term use of immunosuppressants can lead to complications such as diabetes, compromising post-transplant outcomes. In this study, we have characterized the intestinal microbiome (IM) composition at the metagenomic level in the context of hyperglycemia induced by immunosuppressants. Sprague-Dawley rats were subjected to doses of tacrolimus and sirolimus that reliably induce hyperglycemia and an insulin-resistant state. Subsequent exposure to probiotics resulted in reversal of hyperglycemia. 16S rRNA and metagenomic sequencing of stool were done to identify the bacterial genes and pathways enriched in immunosuppression. Bacterial diversity was significantly decreased in sirolimus-treated rats, with 9 taxa significantly less present in both immunosuppression groups: Roseburia, Oscillospira, Mollicutes, Rothia, Micrococcaceae, Actinomycetales and Staphylococcus. Following probiotics, these changes were reversed to baseline. At the metagenomic level, the balance of metabolism was shifted towards the catabolic side with an increase of genes involved in sucrose degradation, similar to diabetes. Conversely, the control rats had greater abundance of anabolic processes and genes involved in starch degradation. Immunosuppression leads to a more catabolic microbial profile, which may influence development of diabetes after SOT. Modulation of the microbiome with probiotics may help in minimizing adverse long-term effects of immunosuppression.

Cognitive function and disability in late life: an ecological validation of the 10/66 battery of cognitive tests among community-dwelling older adults in South India.

BACKGROUND: The 10/66 Dementia Research Group developed and validated a culture and education fair battery of cognitive tests for diagnosis of dementia in population-based studies in low-income and middle-income countries including India. AIMS: This study examined the association between individual domains of the 10/66 battery of cognitive tests and 'disability' and 'functional impairment' in community-dwelling older adults in South India. METHODS: One hundred twenty-nine adults aged 60-90 years residing in Karunapura, in the city of Mysore, were interviewed in their own homes. Cognitive functioning was measured by administering the 10/66 battery of cognitive tests that composes of Community Screening Instrument for Dementia (CSI'D' COGSCORE), verbal fluency (VF) and word list memory recall (WLMR). A reliable informant was interviewed to ascertain if the subject's cognitive problems have resulted in functional impairment. Disability was measured by WHO Disability Schedule-II (DAS). RESULTS: The women had significantly lower CSI'D' COGSCORE score when compared with men (p = 0.002). The presence of 'functional impairment' resulting from cognitive decline was significantly associated with lower scores on VF (p = 0.03), WLMR (p = 0.03) and CSI'D' COGSCOREs (p < 0.01). There was a significant inverse association between WHO DAS II score and WLMR (p = 0.004), VF (0.006) and CSI'D' COGSCORE scores (p ≤ 0.001) even after adjusting for self-reported ischaemic heart disease, stroke, chronic obstructive airway disease, hypertension and diabetes. CONCLUSIONS: Lower scores on individual domains of the 10/66 battery of cognitive tests are associated with higher levels of disability and functional impairment in community-dwelling older adults. These culture and education fair tests are suitable for use in population-based research in India. Copyright © 2015 John Wiley & Sons, Ltd.

Cannabinoid replacement therapy (CRT): Nabiximols (Sativex) as a novel treatment for cannabis withdrawal.

Cannabis is a common recreational drug that is generally considered to have low addictive potential. However, an increasing number of cannabis users are seeking treatment for dependence on the drug. There is interest in using agonist (substitution) pharmacotherapies to treat cannabis dependence and here we outline a novel approach involving a buccal spray (nabiximols) that contains tetrahydrocannabinol (THC) and cannabidiol (CBD). We review recent research with nabiximols and highlight findings relevant to clinical practice.

CT angiography-guided single-stage release of adjacent webspaces in non-Apert syndactyly.

UNLABELLED: We describe the CT angiography protocol and surgical technique utilized at our institution for single-stage release of adjacent web-spaces in non-Apert syndactyly. In a series of seven consecutive hands we analyse syndactyly anatomy, CT angiographic findings, operative details, and complications. Outcomes were assessed with a functional activity evaluation, range of motion, and a parental visual analogue scale. Seven affected hands in four patients underwent single-stage release of adjacent webspaces. In all cases, the CT angiogram correctly predicted the presence of at least one artery supplying each digit. There were no cases of digital ischemia or loss. Angiographically guided, single-stage release of adjacent webspaces is technically feasible and benefits patients by reducing the number of surgical stages and allowing complete release to be achieved at an earlier age compared with the standard multi-stage approach. LEVEL OF EVIDENCE: IV.

Dynamics of Progesterone, TNF- α , and a Metabolite of PGF2 α in Blood Plasma of Beef Cows following Embryo Transfer.

Lactating beef cows previously synchronized for estrus (d 0) were assigned to four treatments to assess their effectiveness in increasing blood progesterone (P4) and its effects on tumor necrosis factor-α (TNF-α) and prostaglandin F2α (PGF2α) after the transfer of embryos. At the time of transfer (d 7), cows received no treatment (control; n = 16), a controlled internal drug releasing device (CIDR; n = 16), human chorionic gonadotropin (hCG; n = 15), or gonadotropin releasing hormone (GnRH; n = 15). Blood samples were taken on d 7, 14, and 21 for analysis of P4 and tumor necrosis factor-α (TNF-α). Blood was collected (every 15 min for 2 h) in half the animals in each treatment group on d 14 and the remaining half on d 21 for analysis of prostaglandin F2α metabolite (PGFM). Retention rates were 56.2, 62.5, 46.7, and 13.3% for cows in the control, CIDR, hCG, and GnRH groups, respectively. Progesterone was greater (P ≤ 0.05) in cows receiving hCG compared to others on d 14. Progesterone in all treatment groups increased from d 7 to d 14 and declined (P ≤ 0.05) from d 14 to d 21. Contrary to pregnant cows, P4 and TNF-α declined from d 7 to d 21 in nonpregnant cows (P ≤ 0.05). Although PGFM increased by d 21, there was no difference between pregnant and nonpregnant cows.

Endocrine response to an ultra-marathon in pre- and post-menopausal women.

Ultra-endurance competitions are becoming increasingly popular but there is limited research on female participants. The purpose of this study was to examine changes in estrogen and the IGF-I system in women after an ultra-marathon. Six pairs of pre- and post- menopausal women were matched for race finish times;mean finish time was 20 hours. Blood samples were drawn 24 hours before the race, at the finish, and 24 hours into recovery. Samples were analysed for estradiol, total IGF-I, IGFBP-1, and intact IGFBP-3. There was a significant increase in estradiol following the race in both groups (P < 0.05). Total IGF-I decreased after the race (P < 0.01) and remained lower in recovery. IGFBP-1 increased after the race (P < 0.001) but returned to pre-race levels after 24 hours, while intact IGFBP-3 was significantly lower post-race and in recovery (P < 0.001). Postmenopausal women had significantly lower estradiol at baseline, but there were no other group differences. These results demonstrate that among recreational female runners, an ultra-marathon is associated with IGF system changes that are consistent with an energy-deficient, catabolic state. Further research is needed to confirm the effect of these endocrine changes on health and performance.

Stooped postures are modified by pretask walking in a simulated weed-pulling task.

Seasonal agricultural workers are hired in some sectors for intermittent manual weed removal, a stoop and grasp harvesting task likely similar to those associated with the high prevalence of musculoskeletal disorders in agriculture. Evaluation of this task in an experimental situation would be useful for identifying and controlling musculoskeletal injury risks, presuming a valid experimental model of the task can be created. The purpose of the present study was to examine how a relevant work-related task, namely prolonged walking, altered the biomechanics of manual weed removal in a laboratory setting. Preliminary field assessments informed the development and analysis of a simulated manual weed removal with two separate conditions: not primed, where 11 participants (4 female, mean age 21.6 years) manually removed a simulated weed six times, and primed, where 23 participants (13 female, mean age 22.1 years) walked 1600 m prior to manually removing the same simulated weed six successive times. Segment end point markers and experimental motion capture were used to determine hip, knee, and ankle angles, as well as toe-target proximity, during weed removal. Significant differences between primed and not primed participants were found for angular displacement at the ankle (t(32) = 5.08, P < .001) and toe-target proximity (t(32) = 2.78, P = .008), where primed participants had increased ankle flexion and a greater distance to the weed, leading to decreased trunk flexion during the harvesting task. These findings suggest that priming can positively influence whole-body postures for manual weed removal.

Smoking mull: a grounded theory model on the dynamics of combined tobacco and cannabis use among adult men.

ISSUE ADDRESSED: Australians' use of cannabis has been increasing. Over a third of Australians (35.4%) have used cannabis at some time in their lives and 10.3% are recent users. Almost two-thirds of cannabis users combine cannabis with tobacco. The aim of this study was to understand the process of mulling - smoking tobacco and cannabis together - using a grounded theory approach. METHODS: Twenty-one in-depth semistructured interviews were conducted with men aged 25-34 and living on the North Coast of New South Wales. Interviews explored participants' smoking practices, histories and cessation attempts. RESULTS: A model describing mulling behaviour and the dynamics of smoking cannabis and tobacco was developed. It provides an explanatory framework that demonstrates the flexibility in smoking practices, including substance substitution - participants changed the type of cannabis they smoked, the amount of tobacco they mixed with it and the devices they used to smoke according to the situations they were in and the effects sought. CONCLUSION: Understanding these dynamic smoking practices and the importance of situations and effects, as well as the specific role of tobacco in mulling, may allow health workers to design more relevant and appropriate interventions. SO WHAT? Combining tobacco with cannabis is the most common way of smoking cannabis in Australia. However, tobacco cessation programmes rarely address cannabis use. Further research to develop evidence-based approaches for mull use would improve cessation outcomes.

Mammography screening: how far is too far?

INTRODUCTION: This study answers the question: 'How far must a Canadian woman travel before the risk of a motor vehicle accident (MVA) outweighs the benefits of mammography screening?'. METHODS: Numbers needed to screen and false positive rates were extracted from information in the breast screening guidelines from the Canadian Task Force on screening for breast cancer. Motor vehicle accidents per billion vehicle kilometres were extracted from Transport Canada. The charts of women undergoing screening mammograms were reviewed to determine the average number of extra trips generated from a false positive mammogram. A formula was devised to determine when the distance travelled and risk of MVA outweighed the benefits of mammogram screening. RESULTS: How far a woman would need travel before the risk of that travel outweighed the benefits of screening mammography is determined by the province in which she lives (location) and her age. The distance of a round trip before the risk of travel outweighed the benefit of screening mammography varied from 65 km to 1151 km, according the patient's age and location. CONCLUSION: Travel risk is rarely discussed in recommending screening examinations. Nevertheless the benefits of screening can be outweighed by the risk of travel. Knowledge of travel risk is essential before recommending screening procedures.

Real-time modelling used for outbreak management during a cholera epidemic, Haiti, 2010-2011.

The emergence of epidemic cholera in post-earthquake Haiti portended a public health disaster of uncertain magnitude. In order to coordinate relief efforts in an environment with limited healthcare infrastructure and stretched resources, timely and realistic projections of the extent of the cholera outbreak were crucial. Projections were shared with Government and partner organizations beginning 5 days after the first reported case and were updated using progressively more advanced methods as more surveillance data became available. The first projection estimated that 105 000 cholera cases would occur in the first year. Subsequent projections using different methods estimated up to 652 000 cases and 163 000-247 000 hospitalizations during the first year. Current surveillance data show these projections to have provided reasonable approximations of the observed epidemic. Providing the real-time projections allowed Haitian ministries and external aid organizations to better plan and implement response measures during the evolving epidemic.

Arabic version of the Global Mental Health Assessment Tool-Primary Care version (GMHAT/PC): a validity and feasibility study.

Mental health services are far from satisfactory in the Eastern Mediterranean Region. The Global Mental Health Assessment Tool-Primary Care version (GMHAT/PC) is a semi-structured, computerized clinical assessment tool that was developed to assist health workers in making quick, convenient and comprehensive standardized mental health assessments. A study was carried out in the United Arab Emirates to evaluate the validity and feasibility of the Arabic version of the GMHAT/PC. Mental health nurses administered the GMHAT/PC Arabic version to 50 patients in mental health and rehabilitation settings and their GMHAT/PC diagnosis was compared with the psychiatrist's independent ICD-10 based clinical diagnosis on the same patients. The nurses found GMHAT/PC easy to administer in an average of 16 minutes. The GMHAT/PC-based diagnosis had a good agreement with the psychiatrist's diagnosis (kappa = 0.91) and a high sensitivity (97%) and specificity (94%).
