Integration of Health Information Technology and Promotion of Personhood in Family-Centered Dementia Care: Intervention Trial.

Alzheimer's disease and related dementias (ADRD) often result in communication deficits that can lead to negative health outcomes as well as complications for caregiving and clinical care. Although augmentative and alternative communication (AAC) devices have demonstrated efficacy in assisting persons living with dementia (PLWD) in communicating, few devices offer customization for the person's care preferences (e.g., clothing, food, activities) or are designed for integration into clinical care and caregiving. To address this issue, our research team is developing a novel electronic AAC prototype with a touchscreen to promote communication and personhood for PLWD. The current article describes the development of this technology and uses the Standard Protocol Items: Recommendations for Interventional Trials (SPIRIT) 2013 Statement to describe the clinical trial that is planned to test its efficacy. TARGETS: PLWD and their care partners. INTERVENTION DESCRIPTION: Use of AAC Plus to promote communication and personhood for PLWD. MECHANISMS OF ACTION: AAC Plus will provide PLWD and care partners a way to communicate PLWD's daily preferences and provide clinical data for health care providers. OUTCOMES: Determine whether enhanced communication of daily preferences of PLWD will improve quality of life of PLWD and their care partners. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT04571502 (Date of registration October 1, 2020). [Research in Gerontological Nursing, 14(5), 225-234.].

Tiny Earth: A Big Idea for STEM Education and Antibiotic Discovery.

The world faces two seemingly unrelated challenges-a shortfall in the STEM workforce and increasing antibiotic resistance among bacterial pathogens. We address these two challenges with Tiny Earth, an undergraduate research course that excites students about science and creates a pipeline for antibiotic discovery.

Effectiveness of Integrated Palliative and Oncology Care for Patients With Acute Myeloid Leukemia: A Randomized Clinical Trial.

IMPORTANCE: Patients with acute myeloid leukemia (AML) receiving intensive chemotherapy experience substantial decline in their quality of life (QOL) and mood during their hospitalization for induction chemotherapy and often receive aggressive care at the end of life (EOL). However, the role of specialty palliative care for improving the QOL and care for this population is currently unknown. OBJECTIVE: To assess the effect of integrated palliative and oncology care (IPC) on patient-reported and EOL outcomes in patients with AML. DESIGN, SETTING, AND PARTICIPANTS: We conducted a multisite randomized clinical trial of IPC (n = 86) vs usual care (UC) (n = 74) for patients with AML undergoing intensive chemotherapy. Data were collected from January 2017 through July 2019 at 4 tertiary care academic hospitals in the United States. INTERVENTIONS: Patients assigned to IPC were seen by palliative care clinicians at least twice per week during their initial and subsequent hospitalizations. MAIN OUTCOMES AND MEASURES: Patients completed the 44-item Functional Assessment of Cancer Therapy-Leukemia scale (score range, 0-176) to assess QOL; the 14-item Hospital Anxiety and Depression Scale (HADS), with subscales assessing symptoms of anxiety and depression (score range, 0-21); and the PTSD Checklist-Civilian version to assess posttraumatic stress disorder (PTSD) symptoms (score range, 17-85) at baseline and weeks 2, 4, 12, and 24. The primary end point was QOL at week 2. We used analysis of covariance adjusting and mixed linear effect models to evaluate patient-reported outcomes. We used Fisher exact test to compare patient-reported discussion of EOL care preferences and receipt of chemotherapy in the last 30 days of life. RESULTS: Of 235 eligible patients, 160 (68.1%) were enrolled; of the 160 participants, the median (range) age was 64.4 (19.7-80.1) years, and 64 (40.0%) were women. Compared with those receiving UC, IPC participants reported better QOL (adjusted mean score, 107.59 vs 116.45; P = .04), and lower depression (adjusted mean score, 7.20 vs 5.68; P = .02), anxiety (adjusted mean score, 5.94 vs 4.53; P = .02), and PTSD symptoms (adjusted mean score, 31.69 vs 27.79; P = .01) at week 2. Intervention effects were sustained to week 24 for QOL (ß, 2.35; 95% CI, 0.02-4.68; P = .048), depression (ß, -0.42; 95% CI, -0.82 to -0.02; P = .04), anxiety (ß, -0.38; 95% CI, -0.75 to -0.01; P = .04), and PTSD symptoms (ß, -1.43; 95% CI, -2.34 to -0.54; P = .002). Among patients who died, those receiving IPC were more likely than those receiving UC to report discussing EOL care preferences (21 of 28 [75.0%] vs 12 of 30 [40.0%]; P = .01) and less likely to receive chemotherapy near EOL (15 of 43 [34.9%] vs 27 of 41 [65.9%]; P = .01). CONCLUSIONS AND RELEVANCE: In this randomized clinical trial of patients with AML, IPC led to substantial improvements in QOL, psychological distress, and EOL care. Palliative care should be considered a new standard of care for patients with AML. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT02975869.

A novel decision aid for acute myeloid leukemia: a feasibility and preliminary efficacy trial.

PURPOSE: Acute myeloid leukemia (AML) is a hematologic malignancy characterized by a poor prognosis but also a paradoxical possibility of cure. This renders decision-making complex and imminent. Unfortunately, many patients with AML misestimate their prognosis and treatment risk. While decision aids can improve illness understanding and reduce decisional conflict, there are no validated decision aids for AML. We developed and tested a novel AML decision aid (NCT03442452). METHODS: Patients (n = 20) were recruited at Duke University from May 2018 to February 2019. Participants completed assessments of AML knowledge and decisional conflict, before and after using the electronic decision aid. The primary endpoint was feasibility (endpoint met if > 80% of study participants completed all study components). Secondary analyses of efficacy were conducted using paired t tests for dependent pre-/post-samples. RESULTS: The primary endpoint of feasibility was met (100% of participants completed all study components). Secondary analyses showed improved knowledge and reduced decisional conflict after using the decision aid. Knowledge scores improved from a mean of 11.8 (out of 18) correct items at baseline to 15.1 correct items after using the decision aid (mean difference 3.35; p < 0.0001). Decisional conflict scores reduced significantly from baseline to post-test as well (mean difference - 6.5; p = 0.02). CONCLUSION: These findings suggest that our AML decision aid is a useful tool to improve the patient experience and promote shared decision-making in AML. A randomized efficacy trial is planned.

Prevalence of ischemic stroke and atrial fibrillation in young patients with migraine national inpatient sample analysis.

OBJECTIVE: To estimate the prevalence of ischemic stroke (IS) and atrial fibrillation (AF) in young patients with migraine and to identify the independent predictors of IS in a large cohort of hospitalized patients. METHODS: A cohort of patients with migraine with aura (MA) and migraine without aura (MO) was identified from the National Inpatient Sample database for the years 2012 to 2015. Ischemic stroke was identified by the International Classification of Diseases-9-CM codes. Binary logistic regression and Chi-square tests were utilized. RESULTS: A total number of 834,875 young patients (18-44 years) were included in this study with a mean age of 33 years. The prevalence of IS was 1.3% and was significantly higher in patients with MA (3.7% versus 1.2%, P <0.001). The prevalence of AF was 0.9% and it was significantly higher in patients with MA (1.2% versus 0.8%, P <0.001). Migraine with aura was an independent predictor of IS (OR 3.23, 95% CI 3.05-3.42, P <0.001) and AF (OR 1.63, 95% CI 1.42-1.88, P <0.001). Other predictors of IS were hypertension (OR 2.2, 95% CI 2.12-2.3, P <0.001), diabetes mellitus (DM) (OR 1.37, 95% CI 1.31-1.42, P <0.001), peripheral vascular disease (PVD) (OR 12.08, 95% CI 11.23-12.98, P <0.001) and smoking (OR 1.37, 95% CI 1.31-1.42, P <0.001). CONCLUSION: In this relatively large study, the overall prevalence of IS in young migraine patients was low at 1.3%. The prevalence of IS and AF was significantly higher in patients with MA. Presence of PVD confers a high risk of IS in young patients with migraine. Migraine aura was observed to be an independent predictor of IS and AF in patients with history of migraine. Optimal control of vascular risk factors in migraine patients appears to be indicated despite the overall low risk.

Parentage of Hydatidiform Moles.

We were presented with the STR (short tandem repeat) profiles from two separate paternity trios. Each trio consisted of a mother, an alleged father, and products of conception (POC) that contained a hydatidiform mole but no visible fetus. In both cases, antecedent pregnancies had followed alleged sexual assaults. Mole classification and pathogenesis are described in order to explain the analyses and statistical reasoning used in each case. One mole exhibited several loci with two different paternal alleles, indicating it was a dispermic (heterozygous) mole. Maternal decidua contaminated the POC, preventing the identification of paternal obligate alleles (POAs) at some loci. The other mole exhibited only one paternal allele/locus at all loci and no maternal alleles, indicating it was a diandric and diploid (homozygous) mole. In each case, traditional calculations were used to determine paternity indices (PIs) at loci that exhibited one paternal allele/locus. PIs at mole loci with two different paternal alleles/locus were calculated from formulas first used for child chimeras that are always dispermic. Combined paternity indices in both mole cases strongly supported the paternity of each suspect.

Factors Associated with Inpatient Mortality after Intracerebral Hemorrhage: Updated Information from the United States Nationwide Inpatient Sample.

BACKGROUND: To use a nationwide database of hospital admissions to assess for trends in inpatient mortality from acute spontaneous intracerebral hemorrhage as well as associated potentially contributing factors. METHODS: Adults with intracerebral hemorrhage in the US National Inpatient Sample database from 2012 to 2015 were included in this study. We assessed for mortality rate as well as potential impact of various comorbidities and demographic factors such as ethnicity and median house hold income on inpatient mortality rate. RESULTS: A total of 47,700 patients were identified with a mean age of 68 years. The overall mortality rate was 24%. Hypertension was the commonest comorbidity (84%) followed by diabetes mellitus (28%). Positive associated factors for mortality rate were coagulopathy (OR 1.28, 95% CI 1.19-1.38, P < .001), female gender (OR 1.12, 95% CI 1.08-1.17, P < .001), and congestive heart failure (OR 1.16, 95% CI 1.08-1.24, P < .001). Age greater than 75 was also associated with higher mortality (P < .001). Factors associated with reduced mortality were hypertension (OR .76, 95% CI .72-0.81, P < .001), hypothyroidism (OR .87, 95% CI .81-.93, P < .001) and obesity (OR .64, 95% CI .59-.69, P < .001). CONCLUSIONS: The inpatient mortality of 24% represents a decline when compared to previous years. Attention to the associated factors with mortality, that we report, could have some potential impact on management. Of interest, we found support for obesity paradox in which obesity may have an actual salutary effect on vascular disease outcome. Our observed paradoxical effects, not only for obesity, but also hypertension and hypothyroidism, warrant further study.

Responses of Salt Marsh Plant Rhizosphere Diazotroph Assemblages to Drought.

Drought has many consequences in the tidally dominated Spartina sp. salt marshes of the southeastern US; including major dieback events, changes in sediment chemistry and obvious changes in the landscape. These coastal systems tend to be highly productive, yet many salt marshes are also nitrogen limited and depend on plant associated diazotrophs as their source of 'new' nitrogen. A 4-year study was conducted to investigate the structure and composition of the rhizosphere diazotroph assemblages associated with 5 distinct plant zones in one such salt marsh. A period of greatly restricted tidal inundation and precipitation, as well as two periods of drought (June-July 2004, and May 2007) occurred during the study. DGGE of nifH PCR amplicons from rhizosphere samples, Principal Components Analysis of the resulting banding patterns, and unconstrained ordination analysis of taxonomic data and environmental parameters were conducted. Diazotroph assemblages were organized into 5 distinct groups (R² = 0.41, p value < 0.001) whose presence varied with the environmental conditions of the marsh. Diazotroph assemblage group detection differed during and after the drought event, indicating that persistent diazotrophs maintained populations that provided reduced supplies of new nitrogen for vegetation during the periods of drought.

A case of chimerism-induced paternity confusion: what ART practitioners can do to prevent future calamity for families.

In the fertility clinic setting, a negative DNA paternity test result usually suggests a sample mix-up likely occurred at the testing company or in the clinic. However, we report a case where, despite repeat negative paternity test results, the alleged father (referred to as "the proband") was confirmed to be the baby's father. The proband, a 34 year-old male, contacted our research group when routine blood testing revealed discrepant blood types between the parents and the baby, repeat paternity tests were negative (excluding the proband as the baby's father), and the fertility clinic found no evidence of any wrongdoing. Microarray technology was utilized to confirm biological relatedness, which revealed an avuncular (uncle/nephew) relationship. Additional tissue samples were analyzed and family studies were conducted at paternity and forensic laboratories using STR-based DNA tests to elucidate the proband's condition of congenital tetragametic chimerism. His paternity was subsequently affirmed and the fertility clinic exonerated of claims of a semen sample mix-up. This case underscores the possibility that some allegations of fertility clinic missteps may be explained by undiagnosed chimerism, a condition where an individual harbors two distinct genomes. We offer specific suggestions for improving laboratory reporting and creating clinical guidelines to aid in identifying and rectifying future cases of false exclusions of paternity due to chimerism.

Patient experiences of acute myeloid leukemia: A qualitative study about diagnosis, illness understanding, and treatment decision-making.

BACKGROUND: Patients with acute myeloid leukemia (AML) face a unique, difficult situation characterized by sudden changes in health, complex information, and pressure to make quick treatment decisions amid sizeable tradeoffs. Yet, little is known about patients' experiences with AML. We used qualitative methods to learn about their experiences with diagnosis and treatment decision-making to identify areas for improvement. METHODS: We recruited hospitalized patients with AML to participate in semi-structured qualitative interviews about their experiences being diagnosed with AML, receiving information, and making a treatment decision. Interviews were conducted during their hospitalization for induction chemotherapy. We analyzed data by using a constant comparison approach. RESULTS: Thirty-two patients completed an interview. Four main themes emerged: (a) shock and suddenness, (b) difficulty processing information, (c) poor communication, and (d) uncertainty. Patients frequently described their diagnosis as shocking. They also felt that the amount of information was too great and too difficult to process, which negatively impacted their understanding. Patients frequently described a lack of emotional support from clinicians and described uncertainty about their prognosis, the number and nature of available treatments, and what to expect from treatment. CONCLUSIONS: Acute myeloid leukemia poses a sudden, emotionally challenging, information-laden situation, where little time is available to make important decisions. This results in difficulty processing information and is sometimes complicated by a lack of emotive communication from clinicians. Results indicate a need for targeted interventions to improve AML patients' understanding of illness and treatment options and to address their traumatic experiences around diagnosis.

Medicinal-Induced Behavior Disorders.

Commonly used medications can have neuropsychiatric and behavioral effects that may be idiosyncratic or metabolic in nature, or a function of interactions with other drugs, toxicity, or withdrawal. This article explores an approach to the patient with central nervous system toxicity, depending on presentation of sedation versus agitation and accompanying physical signs and symptoms. The effects of antihypertensives, opioids, antibiotics, antiepileptic agents, steroids, Parkinson's disease medications, antipsychotics, medications for human immunodeficiency virus infection, cancer chemotherapeutics, and immunotherapies are discussed. A look at the prevalence of adverse reactions to medications and the errors underlying such occurrences is included.

Clinical manifestations of cerebellar disease.

Clinical manifestations of cerebellar disease include ataxia and tremor, as well as nystagmus, dysarthria, and cognitive dysfunction. Recognition of the cerebellar pattern of disease can aid in the prompt and correct diagnosis and lead to appropriate treatment and rehabilitation to minimize disability.

Preference-based utility scores for adverse events associated with the treatment of gynecologic cancers.

OBJECTIVE: Our goals were to (1) define a set of descriptive health states related to adverse events (AEs) associated with gynecologic cancer treatment with radical surgery and chemoradiation and (2) derive a set of quality of life-related utility scores corresponding to these health states. METHODS: We developed a list of health states for grade 3/4 AEs related to gynecologic cancer treatment. Using the visual analog scale score and time trade-off (TTO) methods, valuation of each health state was obtained through interviews of 60 volunteers (15 cervical cancer survivors treated with surgery and/or chemoradiation and 45 women without a cancer diagnosis). Health states were ranked by mean/median TTO scores. Wilcoxon rank sum test was used to compare central tendencies related to patient and volunteer characteristics. RESULTS: Patients and volunteers agreed on their preference rankings, with highest preference given to infection (median TTO = 1.0) and thrombosis (median TTO = 0.97). Lowest preference was assigned to radiation proctitis (median TTO = 0.87) and gastrointestinal fistula formation (median TTO = 0.83). Utility scores for the majority of health states were not significantly associated with age, race, parity, patient or volunteer status, history of abnormal Pap smear, stage of cervical cancer diagnosis, or personal experience of a serious treatment-related AE. CONCLUSIONS: This study helps establish preferences and quality-of-life utility scores for health states related to toxicities from surgery, radiation, and chemotherapy for gynecologic cancer treatment. Such information can be used to inform medical decision making/counseling and may be applied to future comparative effectiveness models in which radical surgery and/or chemoradiation are considered.

Streamlining of intra-operative parathyroid hormone measurements for cure during parathyroidectomy.

BACKGROUND: The timing of intraoperative parathyroid hormone measurements during parathyroidectomy for the treatment of primary hyperparathyroidism is quite variable. Although a 50% decrease after excision is considered predictive of cure, it is not known which combination of measurements is most useful. METHODS: Two hundred thirteen patients underwent resection of solitary parathyroid adenomas. Sex, age, intraoperative parathyroid hormone level at baseline, before adenoma removal (T0), and 5 minutes (T5) and 10 minutes (T10) after adenoma removal; and 50% decrease were tested for associations with cure. RESULTS: A 50% decrease in intraoperative parathyroid hormone level was 95% sensitive for cure (95% confidence interval, 89% to 98%) but did not predict cure for individual patients. A decrease into the normal range was not correlated with cure (P > .50). However, a 50% decrease from T0 to T10 was 97% predictive of cure (odds ratio, 6.5; P = .08). CONCLUSIONS: The decrease in parathyroid hormone level from T0 to T10 during parathyroidectomy was most predictive of cure of primary hyperparathyroidism. A decrease into the normal range did not improve the performance characteristics of this test.

Multiple sclerosis and pain.

Despite the common belief that multiple sclerosis (MS) is a painless disease, several studies contradict this. There are a significant number of MS patients who actually suffer from painful conditions such as central and peripheral neuropathy, migraines, trigeminal neuralgia, painful tonic spasms, complex regional pain syndrome, glossopharyngeal neuralgia, and transverse myelitis. In addition, MS relapses are usually painful with many patients complaining of paroxysmal dystonia and neuropathic pain during these episodes. Additionally, treatments for MS such as use of beta-interferons may be associated with headache and pain at the injection site. The pathophysiology of pain in MS is poorly understood, but may be related to the development of demyelinating lesions involving certain neuroanatomic pathways such as the spinothalamic tract. Management of pain in MS patients is a therapeutic challenge for clinicians. Currently, various pharmacological agents such as antiepielptics, non-steroidal anti-inflammatory agents, and even corticosteroids are used to suppress various painful conditions associated with MS. Non-pharmacological procedures such as massage therapy have also been used in the treatment of MS patients. The authors present a review of recent findings in pathophysiology and management of pain in MS patients.

Specificity of Salt Marsh Diazotrophs for Vegetation Zones and Plant Hosts: Results from a North American marsh.

Salt marshes located on the east coast of temperate North America are highly productive, typically nitrogen-limited, and support diverse assemblages of free-living nitrogen fixing (diazotrophic) bacteria. This article reviews and analyzes data from North Inlet estuary (SC, USA), addressing diazotroph assemblage structure and the influence of plant host and environmental conditions on the assemblage. The North Inlet estuary is a salt marsh ecosystem in which anthropogenic influences are minimal and the distributions of diazotrophs are governed by the natural biota and dynamics of the system. Denaturing gradient gel electrophoresis fingerprinting and phylogenetic analyses of recovered sequences demonstrated that the distributions of some diazotrophs reflect plant host specificity and that diazotroph assemblages distributed across marsh gradients are also heavily influenced by edaphic conditions. Broadly distributed diazotrophs that are capable of maintaining populations under all environmental conditions spanning such gradients are also present in these assemblages. Statistical analyses indicate that the structures of diazotroph assemblages in different vegetation zones are significantly (p < 0.01) different. New data presented here demonstrate the heterogeneity of salt marsh rhizosphere microenvironments, and corroborate previous findings from different plant hosts growing at several locations within this estuary. The data from these collected works support the hypothesis that the biogeography of microorganisms is non-random and these biogeographic patterns are predictable.

Utility scores and treatment preferences for clinical early-stage cervical cancer.

OBJECTIVES: To determine utility scores for health states relevant to the treatment of early-stage, high-risk cervical cancer. METHODS: Seven descriptive health states incorporating the physical and emotional aspects of medical treatment, recovery, and prognosis were developed. Forty-five female volunteers valuated each health state using the visual analogue score (VAS) and time trade off (TTO) methods. Treatment options were ranked by mean and median TTO scores. The 95% confidence intervals were calculated to determine the statistical significance of ranking preferences. The Wilcoxon rank-sum test was used to compare central tendencies related to age, race, parity, and subject history of abnormal cervical cytology. RESULTS: VAS and TTO scores were highly correlated. Volunteers ranked minimally invasive radical hysterectomy with low-risk features as most preferred (mean TTO = 0.96; median TTO = 1.00) and aborted radical hysterectomy followed by chemoradiation as least preferred (mean TTO = 0.69; median TTO = 0.83). Health states that included radical surgery were ranked higher than those that included chemoradiation, either in the adjuvant or primary setting. When survival was comparable, volunteers rated radical hysterectomy with high-risk pathology followed by adjuvant chemoradiation (mean TTO = 0.78; median TTO = 0.92; 95% CI: 0.69-0.87) similarly to chemoradiation alone (mean TTO = 0.76; median TTO 0.90; 95% CI: 0.66-0.86; p = NS). Utility scores for the majority of health states were not significantly associated with age, race, parity, or subject history of abnormal cervical cytology. CONCLUSION: Subjects consistently preferred surgical excision to treat early-stage, high-risk cervical cancer and chose a minimally invasive approach. Such utility scores can be used to incorporate quality-of-life effects into comparative-effectiveness models for cervical cancer.
