RESUMEN

Alaska Native and American Indian (ANAI) people experience dramatic alcohol-related health disparities compared to the general US population. Although the majority of ANAI people reside in urban settings (>70%), data are sparse on alcohol abstinence among urban ANAI people with alcohol use disorder (AUD). We conducted a qualitative study using a phenomenological approach to examine the experiences of 20 urban ANAI adults recovering from AUD. Participants' narratives had their own unique dimensions but shared a clear, interrelated trajectory of pre-alcohol recovery, a turning point, and ongoing alcohol recovery. All participants reported a combination of external and internal motivation to stop using alcohol.

RESUMEN

BACKGROUND: There is very little research into the way that offender management strategies impinge on the practices and decision-making of palliative care personnel in community settings. AIMS: To improve understanding of the challenges that community palliative care service providers encounter when caring for people who have been sentenced to custody and are under the supervision of the prison or probation services. METHODS: This paper discusses one part of a larger multidisciplinary study on bereavement, loss and grief in the criminal justice system. It reports the findings from a focus group with 10 health professionals working within specialist community palliative care services. Thematic analysis was undertaken to identify and explicate the most significant themes arising from the transcript data. RESULTS: There were situations where the participants were able to identify that patients were under the jurisdiction of the criminal justice system or had relatives in custody. Three themes emerged that highlighted distinctive aspects of providing care to this patient group. These themes were: patients under prison, probation or police supervision altered the dynamics of care provision; prisoners were restricted from supporting or contacting their dying relatives in the community; and participants (professionals) were obstructed from supporting patients at home because of criminal or antisocial behaviour by relatives of the dying. CONCLUSIONS: Health professionals face multiple challenges that curtail them from fully realising the aims of palliative care for patients and relatives under criminal justice supervision, in ways that merit further consideration and research.

RESUMEN

AIM: To explore the perceptions and experiences of people with osteoarthrits (OA) and rheumatoid arthritis (RA) regarding the knowledge and skills they want nurses and allied health professionals (AHPs) to have to manage their care needs. METHOD: Two condition-specific focus groups were conducted in London with five people with OA and eight people with RA in January 2011. A semistructured interview guide was used. The focus groups were audiotaped and the transcripts analysed using content analysis. RESULTS: Shared and condition-specific themes were identified. The shared themes were: living with pain; the need for self-management; and meaningful consultation. The condition-specific themes were: no experts in OA; and wanting to talk in the RA participants. CONCLUSION: People with OA and RA wanted nurses and AHPs to listen, empathise and help them to manage their condition, especially the pain. Participants with RA would value psychological support. We need to ensure that nurses and AHPs have the knowledge and skills to address these needs.

RESUMEN

OBJECTIVES: Attitudes about alcohol misuse and dependence influence alcohol use and help-seeking behavior. Alaska Native and American Indian (AN/AI) people have higher rates of alcohol-related morbidity and mortality but engage in treatment at lower rates than the general population. No validated instruments exist to assess attitudes of AN/AI people about alcohol misuse and dependence to inform treatment and prevention efforts. This study aimed to develop an instrument to assess public attitudes among AN/AI people of alcohol misuse and dependence. METHODS: This multiphase, mixed-methods study was conducted at Southcentral Foundation, a tribally owned health system serving 65,000 AN/AI people in Alaska. We conducted focus groups and interviews with health system users, providers, and leaders to adapt the Public Attitudes About Addiction Survey. The adapted instrument was piloted with 200 people. Cognitive interviews and exploratory and confirmatory factor analyses were used to refine the instrument, which were then administered to 777 AN/AI people. RESULTS: Initial exploratory factor analysis identified 5 factors, including 3 from the original Public Attitudes About Addiction Survey (moral, disease, nature), a combined psychology and sociology factor (psychosocial), and a new factor (environment). A final 4-factor model (psychosocial, moral, disease, nature) with 14 items had good fit with root mean square error of approximation (0.035; comparative fit index = 0.977; Tucker-Lewis index = 0.970; standardized root mean residual = 0.040) and loadings ranging from 0.41 to 0.80. CONCLUSIONS: This study developed the first instrument to assess AN/AI attitudes about alcohol misuse and dependence. This instrument has potential to inform alcohol-related treatment in AN/AI communities. Future research is warranted to adequately measure place-based contributors salient to AN/AI people.

RESUMEN

Conventionally, therapeutic assessments, interventions, and treatments have focussed on death-related "losses and grief" responses. It is purported that the COVID-19 aftermath has resulted in losses that cannot always be encapsulated using this method. In search of reasoning, models and theories that explain the sweeping mass destruction that COVID-19 has caused, key concepts arise in terms of how we should deal with losses and in turn support patients in the health and social care sector, (notwithstanding formal therapeutic services). There is a crucial need to embrace ambiguous loss and disenfranchised grief into everyday terminology and be acquainted with these issues, thereby adapting how services/clinicians now embrace loss and grief work. Integral to this process is to recognize that there has been a disproportionate impact on Black and minority ethnic communities, and we now need to ensure services are "seriously culturally competent." Primary Care services/IAPT/health and social care/voluntary sector are all likely to be at the forefront of delivering these interventions and are already established gatekeepers. So, this article discusses the prognostic therapeutic response to non-death related losses and grief, not restricted to the formal echelons of therapeutic provision.

RESUMEN

INTRODUCTION: The American Indian/Alaska Native (AI/AN) suicide rate in Alaska is twice the state rate and four times the U.S. rate. Healthcare systems need innovative methods of suicide risk detection. The Mental Health Research Network (MHRN) developed suicide risk prediction algorithms in a general U.S. METHODS: We applied MHRN predictors and regression coefficients to electronic health records of AI/AN patients aged ≥13 years with behavioral health diagnoses and primary care visits between October 1, 2016, and March 30, 2018. Logistic regression assessed model accuracy for predicting and stratifying risk for suicide attempt within 90 days after a visit. We compared expected to observed risk and assessed model performance characteristics. RESULTS: 10,864 patients made 47,413 primary care visits. Suicide attempt occurred after 589 (1.2%) visits. Visits in the top 5% of predicted risk accounted for 40% of actual attempts. Among visits in the top 0.5% of predicted risk, 25.1% were followed by suicide attempt. The best fitting model had an AUC of 0.826 (95% CI: 0.809-0.843). CONCLUSIONS: The MHRN model accurately predicted suicide attempts among AI/AN patients. Future work should develop clinical and operational guidance for effective implementation of the model with this population.

RESUMEN

OBJECTIVES: Opioid-related disparities are magnified among Alaska Native and American Indian (ANAI) people. Yet, no outcome studies on medication for addiction treatment, an effective treatment in other populations, among ANAI people exist. The objective of this study was to identify variables associated with buprenorphine/naloxone retention among ANAI people with opioid use disorder (OUD). METHODS: The sample was 240 ANAI adults in Anchorage, Alaska who received buprenorphine/naloxone treatment for an OUD. We gathered data from the electronic health record from January 1, 2015 to December 31, 2019. We used survival analysis to explore possible predictors (demographic variables, psychiatric comorbidity, medical severity, previous opioid prescriptions, previous injury, alcohol use disorder, and co-occurring substance use) of length of treatment retention (in days) while accounting for right censoring. RESULTS: We found that 63% of the 240 patients were retained in buprenorphine/naloxone treatment at 90 days, 51% at 6 months, and 40% at 1 year, slightly lower than the general US population. Younger age (hazard ratio 1.69, 95% confidence intervals 1.17-2.45) and co-occurring substance use (hazard ratio 2.95, 95% confidence intervals 1.99-4.38) were associated with increased rate of buprenorphine/naloxone treatment discontinuation. CONCLUSIONS: Younger patients and those with co-occurring substance use remain at higher risk of discontinuing buprenorphine/naloxone treatment for OUD in this population of ANAI people. Treatment programs serving ANAI people may consider paying special attention to patients with these characteristics to prevent treatment discontinuation. Our study highlights the need to address poly-substance use among ANAI people in treatment.

RESUMEN

Importance: Many American Indian and Alaska Native communities are disproportionately affected by problems with alcohol use and seek culturally appropriate and effective interventions for individuals with alcohol use disorders. Objective: To determine whether a culturally tailored contingency management intervention, in which incentives were offered for biologically verified alcohol abstinence, resulted in increased abstinence among American Indian and Alaska Native adults. This study hypothesized that adults assigned to receive a contingency management intervention would have higher levels of alcohol abstinence than those assigned to the control condition. Design, Setting, and Participants: This multisite randomized clinical trial, the Helping Our Native Ongoing Recovery (HONOR) study, included a 1-month observation period before randomization and a 3-month intervention period. The study was conducted at 3 American Indian and Alaska Native health care organizations located in Alaska, the Pacific Northwest, and the Northern Plains from October 10, 2014, to September 2, 2019. Recruitment occurred between October 10, 2014, and February 20, 2019. Eligible participants were American Indian or Alaska Native adults who had 1 or more days of high alcohol-use episodes within the last 30 days and a current diagnosis of alcohol dependence. Data were analyzed from February 1 to April 29, 2020. Interventions: Participants received treatment as usual and were randomized to either the contingency management group, in which individuals received 12 weeks of incentives for submitting a urine sample indicating alcohol abstinence, or the control group, in which individuals received 12 weeks of incentives for submitting a urine sample without the requirement of alcohol abstinence. Regression models fit with generalized estimating equations were used to assess differences in abstinence during the intervention period. Main Outcomes and Measures: Alcohol-negative ethyl glucuronide (EtG) urine test result (defined as EtG<150 ng/mL). Results: Among 1003 adults screened for eligibility, 400 individuals met the initial criteria. Of those, 158 individuals (39.5%; mean [SD] age, 42.1 [11.4] years; 83 men [52.5%]) met the criteria for randomization, which required submission of 4 or more urine samples and 1 alcohol-positive urine test result during the observation period before randomization. A total of 75 participants (47.5%) were randomized to the contingency management group, and 83 participants (52.5%) were randomized to the control group. At 16 weeks, the number who submitted an alcohol-negative urine sample was 19 (59.4%) in the intervention group vs 18 (38.3%) in the control group. Participants randomized to the contingency management group had a higher likelihood of submitting an alcohol-negative urine sample (averaged over time) compared with those randomized to the control group (odds ratio, 1.70; 95% CI, 1.05-2.76; P = .03). Conclusions and Relevance: The study's findings indicate that contingency management may be an effective strategy for increasing alcohol abstinence and a tool that can be used by American Indian and Alaska Native communities for the treatment of individuals with alcohol use disorders.

RESUMEN

Introduction: Advance care planning (ACP) is a process in which patients, families, and providers discuss and plan for desired treatment goals. American Indian and Alaska Native people (AI/AN) have higher prevalence of many serious, life-limiting illnesses compared with the general population; yet AI/ANs use ACP considerably less than the overall population. Method: We conducted a qualitative study to culturally adapt an existing ACP intervention for AI/ANs in two primary care settings. Results: We found that it is important to incorporate patients' cultural values and priorities into ACP, determine who the patient wants involved in ACP conversations, and consider the culturally and locally relevant barriers and facilitators when developing an ACP intervention with AI/AN communities. Discussion: At the core, ACP interventions should be clear and understandable across populations and tailored to facilitate culturally appropriate and meaningful patient-provider communication. Our results and methodology of culturally adapting an intervention may be applicable to other underrepresented populations.

RESUMEN

OBJECTIVES: The objective of this study was to examine the predictive validity of the Stages of Change Readiness and Treatment Eagerness Scale (SOCRATES) among Alaska Native and American Indian (ANAI) people with an alcohol use disorder. METHODS: The sample was 170 ANAI adults with an alcohol use disorder living in Anchorage, Alaska who were part of a larger alcohol intervention study. The primary outcome of this study was alcohol use as measured by mean urinary ethyl glucuronide (EtG). EtG urine tests were collected at baseline and then up to twice a week for four weeks. We conducted bivariate linear regression analyses to evaluate associations between mean EtG value and each of the three SOCRATES subscales (Recognition, Ambivalence, and Taking Steps) and other covariates such as demographic characteristics, alcohol use history, and chemical dependency service utilization. We then performed multivariable linear regression modeling to examine these associations after adjusting for covariates. RESULTS: After adjusting for covariates, mean EtG values were negatively associated with the Taking Steps (P = 0.017) and Recognition (P = 0.005) subscales of the SOCRATES among ANAI people living in Alaska. We did not find an association between mean EtG values and the Ambivalence subscale (P = 0.129) of the SOCRATES after adjusting for covariates. CONCLUSIONS: Higher scores on the Taking Steps and Recognition subscales of the SOCRATES at baseline among ANAI people predicted lower mean EtG values. This study has important implications for communities and clinicians who need tools to assist ANAI clients in initiating behavior changes related to alcohol use.

RESUMEN

Polar bears (Ursus maritimus) are experiencing rapid and substantial changes to their environment due to global climate change. Polar bears of the southern Beaufort Sea (SB) have historically spent most of the year on the sea ice. However, recent reports from Alaska indicate that the proportion of the SB subpopulation observed on-shore during late summer and early fall has increased. Our objective was to investigate whether this on-shore behavior has developed through genetic inheritance, asocial learning, or through social learning. From 2010 to 2013, genetic data were collected from SB polar bears in the fall via hair snags and remote biopsy darting on-shore and in the spring from captures and remote biopsy darting on the sea ice. Bears were categorized as either on-shore or off-shore individuals based on their presence on-shore during the fall. Levels of genetic relatedness, first-order relatives, mother-offspring pairs, and father-offspring pairs were determined and compared within and between the two categories: on-shore versus off-shore. Results suggested transmission of on-shore behavior through either genetic inheritance or social learning as there was a higher than expected number of first-order relatives exhibiting on-shore behavior. Genetic relatedness and parentage data analyses were in concurrence with this finding, but further revealed mother-offspring social learning as the primary mechanism responsible for the development of on-shore behavior. Recognizing that on-shore behavior among polar bears was predominantly transmitted via social learning from mothers to their offspring has implications for future management and conservation as sea ice continues to decline.

RESUMEN

Preclinical data indicates that cyclooxygenase-2 (COX-2) inhibition impairs plasma cell growth and potentially synergizes with thalidomide. We performed a trial in previously treated patients with myeloma using thalidomide up to a maximum dose of 800 mg/d with celecoxib (400 mg bid). Outcomes were compared with a prior trial of thalidomide. Sixty-six patients with median age of 67 (range, 43-85) received a median dose of thalidomide and celecoxib of 400 and 800 mg/d, respectively, with median durations of treatment of 27 and 13 weeks, respectively. The most common toxicities associated with premature discontinuation of celecoxib (n = 30 of 53, 57%) were fluid retention and deterioration of renal function. Overall response rate (RR) was 42% and with 20 months median follow-up; the actuarial median progression-free survival and overall survival were 6.8 and 21.4 months, respectively. Unlike our prior study, age >65 years was not predictive of inferior RR due to improvement in RR in older patients with the combination (37% versus 15%, P = 0.08). The RR was superior in patients who received a total dose of celecoxib exceeding 40 g in the first 8 weeks of therapy (62% versus 30%, P = 0.021). Progression-free survival and overall survival were also improved. Other predictors for inferior progression-free survival were age >65 years (P = 0.016) and elevated beta(2)-microglobulin (P = 0.017). This study provides evidence that the addition of high-dose celecoxib adds to the antimyeloma activity of thalidomide but this comes with unacceptable toxicity. Future studies should use newer COX-2 inhibitors with thalidomide, or their respective derivatives.

RESUMEN

In the Arctic Ocean's southern Beaufort Sea (SB), the length of the sea ice melt season (i.e., period between the onset of sea ice break-up in summer and freeze-up in fall) has increased substantially since the late 1990s. Historically, polar bears (Ursus maritimus) of the SB have mostly remained on the sea ice year-round (except for those that came ashore to den), but recent changes in the extent and phenology of sea ice habitat have coincided with evidence that use of terrestrial habitat is increasing. We characterized the spatial behavior of polar bears spending summer and fall on land along Alaska's north coast to better understand the nexus between rapid environmental change and increased use of terrestrial habitat. We found that the percentage of radiocollared adult females from the SB subpopulation coming ashore has tripled over 15 years. Moreover, we detected trends of earlier arrival on shore, increased length of stay, and later departure back to sea ice, all of which were related to declines in the availability of sea ice habitat over the continental shelf and changes to sea ice phenology. Since the late 1990s, the mean duration of the open-water season in the SB increased by 36 days, and the mean length of stay on shore increased by 31 days. While on shore, the distribution of polar bears was influenced by the availability of scavenge subsidies in the form of subsistence-harvested bowhead whale (Balaena mysticetus) remains aggregated at sites along the coast. The declining spatio-temporal availability of sea ice habitat and increased availability of human-provisioned resources are likely to result in increased use of land. Increased residency on land is cause for concern given that, while there, bears may be exposed to a greater array of risk factors including those associated with increased human activities.

RESUMEN

AIM: The purpose of the present study was to identify the educational needs of rheumatology nurses and allied healthcare professionals (AHPs) working with people with osteoarthritis (OA) and rheumatoid arthritis (RA). METHODS: A cross-sectional national online survey was carried out. RESULTS: The survey was completed by 162 health care practitioners. Seventy-one per cent of respondents had the knowledge and skills to manage the care of a person with RA. The elements of care for which the respondents were either unsure or did not have the necessary knowledge and skills related to providing advice on exercise (37%) and pain medication (30%) to people with RA. There was a consistent tendency for respondents to be less confident in their knowledge and skills when caring for people with OA, with respondents reporting that they were either unsure or did not have the necessary knowledge and skills to advise on appropriate exercise (61%), or medication for the management of pain (45%) or the management of ongoing care (51%). CONCLUSIONS: Current and future educational programmes on RA and OA management should provide nurses and AHPs with the opportunity to develop knowledge and skills in providing advice on exercise and pain medication.

RESUMEN

Despite the best available agents to prevent mucositis, most patients receiving high-dose chemoradiotherapy regimens experience severe mucositis, and new therapies are needed. In this study, we evaluated the safety and tolerability of a milk-derived growth factor extract (PV701 mouthwash) intended to prevent oral mucositis (OM) after carmustine, etoposide, cytosine arabinoside, and melphalan (BEAM) chemotherapy. PV701 mouthwash (15 mL x 13.5 mg/mL) was administered 6 times a day for 12 days, from day--6 to day +5, to patients with lymphoma, who were given BEAM on day--6 to day--2, with autologous stem cells infused on day 0. Dose de-escalation of PV701 was planned if dose-limiting toxicities occurred. The severity and duration of OM, the duration of enteral/parenteral feeding, the requirement for intravenous opiates, and admission to intensive care were recorded. Outcomes were also compared with those of historical control patients. Nine patients received PV701 13.5 mg/mL. PV701 was well tolerated, and no dose-limiting toxicities were observed. Compared with 89 historical controls, the 9 PV701-treated patients had significantly less frequent grade 2 or 3 OM ( P=.0006) and had grade>or=3 OM for an estimated 5 fewer days ( P=.0003). There was a reduction in the need for enteral/parenteral feeding ( P=.012), its duration ( P=.010), and its frequency ( P=.022) and in the duration of intravenous opiates ( P=.0006). We conclude that PV701 mouthwash is readily administered with minimal side effects at a dose of 1215 mg/d, and further investigation of this agent is warranted.

RESUMEN

Relapsed or refractory multiple myeloma has a poor outlook. Some patients respond to thalidomide; however, criteria for predicting response have not been conclusively identified. We initiated a prospective multicenter phase 2 trial in patients with relapsed/refractory myeloma using thalidomide up to the maximum dose, 800 mg/d. Interferon-alpha-2B (1.5-3.0 x 10(6) U, subcutaneously, 3 times per week) was added at week 12 if disease was responsive or stable. Patients intolerant of interferon continued thalidomide alone. Thalidomide with or without interferon was continued until disease progression. Objectives were to determine toxicity, response rate (RR), progression-free survival (PFS), and overall survival (OS) and to elucidate relevant prognostic factors. We enrolled 75 patients, with median age 64 years (range, 36-83 years). Median individual maximum-tolerated dose of thalidomide was 600 mg/d; 41% reached 800 mg/d. Overall RR was 28%, and 55% stable disease (SD). The only predictor for response was age 65 years or younger (38% versus 17%; P =.043). At 18 months median follow-up, the actuarial median PFS and OS were 5.5 and 14.6 months, respectively. Multivariate analysis for OS demonstrated age exceeding 65 years (median, 9.2 months versus longer than 26 months; P =.011), raised serum lactate dehydrogenase (P =.002), and raised serum creatinine (P =.007) predicted inferior outcomes. Nineteen patients received interferon. Ten discontinued owing to toxicity. Four of 12 patients who received interferon for longer than 4 weeks were converted from SD to partial response. Our findings confirm substantial activity of thalidomide in relapsed/refractory myeloma. Interferon may improve response in selected patients, but is often not tolerated. The inferior outcome demonstrated in those with the identified prognostic factors is important in planning management for such patients.
