The millimeter-wave spectrum of the SiP radical (X2Πi): Rotational perturbations and hyperfine structure.

The millimeter/submillimeter-wave spectrum of the SiP radical (X2Πi) has been recorded using direct absorption spectroscopy in the frequency range of 151-532 GHz. SiP was synthesized in an AC discharge from the reaction of SiH4 and gas-phase phosphorus, in argon carrier gas. Both spin-orbit ladders were observed. Fifteen rotational transitions were measured originating in the Ω = 3/2 ladder, and twelve in the Ω = 1/2 substate, each exhibiting lambda doubling and, at lower frequencies, hyperfine interactions from the phosphorus nuclear spin of I = 1/2. The lambda-doublets in the Ω = 1/2 levels appeared to be perturbed at higher J, with the f component deviating from the predicted pattern, likely due to interactions with the nearby excited A2Σ+ electronic state, where ΔEΠ-Σ âˆ¼ 430 cm-1. The data were analyzed using a Hund's case aß Hamiltonian and rotational, spin-orbit, lambda-doubling, and hyperfine parameters were determined. A 2Π/2Σ deperturbation analysis was also performed, considering spin-orbit, spin-electronic, and L-uncoupling interactions. Although SiP is clearly not a hydride, the deperturbed parameters derived suggest that the pure precession hypothesis may be useful in assessing the 2Π/2Σ interaction. Interpretation of the Fermi contact term, bF, the spin-dipolar constant, c, and the nuclear spin-orbital parameter, a, indicates that the orbital of the unpaired electron is chiefly pπ in character. The bond length in the v = 0 level was found to be r0 = 2.076 Å, suggestive of a double bond between the silicon and phosphorus atoms.

Psychologic wellness of PA, NP, and physician hospitalists during the COVID-19 pandemic.

OBJECTIVES: Hospitalists, comprising PAs, NPs, and physicians, manage patients hospitalized with COVID-19. To guide the development of support programs, this study compared the psychologic wellness of hospitalist PAs, NPs, and physicians during the COVID-19 pandemic. METHODS: We surveyed hospitalists in 16 hospitals at Mayo Clinic, from May 4 to 25, 2020. We used PROMIS surveys for self-reported global well-being (two single-item measures), anxiety, social isolation, and emotional support, before and during the pandemic. Linear and logistic regression models were adjusted for personal and professional factors. RESULTS: The response rate was 52.2% (N = 154/295). In adjusted linear regression models, the change in scores (before minus during pandemic) for anxiety, social isolation, and emotional support was similar for PAs and NPs compared with physicians. In adjusted logistic regression models, physicians, compared with PAs and NPs, had a higher odds of top global well-being for mental health (adjusted odds ratio [95% confidence interval]: 2.82 [1.12, 7.13]; P = .03) and top global well-being for social activities and relationships (adjusted odds ratio 4.08 [1.38, 12.08]; P = .01). CONCLUSIONS: During the COVID-19 pandemic, global well-being was lower for PAs and NPs compared with physician hospitalists. These results can guide support programs for hospitalists.

Targeted next-generation sequencing of adult gliomas for retrospective prognostic evaluation and up-front diagnostics.

AIMS: We aimed to reclassify a population-based cohort of 529 adult glioma patients to evaluate the prognostic impact of the 2016 World Health Organization (WHO) central nervous system tumour classification. Moreover, we evaluated the feasibility of gene panel next-generation sequencing (NGS) in daily diagnostics of 225 prospective glioma patients. METHODS: The retrospective cohort was reclassified according to WHO 2016 criteria by immunohistochemistry for IDH-R132H, fluorescence in situ hybridization for 1p/19q-codeletion and gene panel NGS. All tumours of the prospective cohort were subjected to NGS analysis up-front. RESULTS: The entire population-based cohort was successfully reclassified according to WHO 2016 criteria. NGS results were obtained for 98% of the prospective patients. Survival analyses in the population-based cohort confirmed three major prognostic subgroups, that is, isocitrate dehydrogenase (IDH)-mutant and 1p/19q-codeleted oligodendrogliomas, IDH-mutant astrocytomas and IDH-wildtype glioblastomas. The distinction between WHO grade II and III was prognostic in patients with IDH-mutant astrocytoma. The survival of patients with IDH-wildtype diffuse astrocytomas carrying TERT promoter mutation and/or EGFR amplification overlapped with the poor survival of IDH-wildtype glioblastoma patients. CONCLUSIONS: Gene panel NGS proved feasible in daily diagnostics. In addition, our study confirms the prognostic role of glioma classification according to WHO 2016 in a large population-based cohort. Molecular features of glioblastoma in IDH-wildtype diffuse glioma were linked to poor survival corresponding to IDH-wildtype glioblastoma patients. The distinction between WHO grade II and III retained prognostic significance in patients with IDH-mutant diffuse astrocytic gliomas.

Bridging the age gap in breast cancer: impact of omission of breast cancer surgery in older women with oestrogen receptor-positive early breast cancer on quality-of-life outcomes.

BACKGROUND: Primary endocrine therapy may be an alternative treatment for less fit women with oestrogen receptor (ER)-positive breast cancer. This study compared quality-of-life (QoL) outcomes in older women treated with surgery or primary endocrine therapy. METHODS: This was a multicentre, prospective, observational cohort study of surgery or primary endocrine therapy in women aged over 70 years with operable breast cancer. QoL was assessed using European Organisation for Research and Treatment of cancer QoL questionnaires QLQ-C30, -BR23, and -ELD14, and the EuroQol Five Dimensions 5L score at baseline, 6 weeks, and 6, 12, 18, and 24 months. Propensity score matching was used to adjust for baseline variation in health, fitness, and tumour stage. RESULTS: The study recruited 3416 women (median age 77 (range 69-102) years) from 56 breast units. Of these, 2979 (87.2 per cent) had ER-positive breast cancer; 2354 women had surgery and 500 received primary endocrine therapy (125 were excluded from analysis due to inadequate data or non-standard therapy). Median follow-up was 52 months. The primary endocrine therapy group was older and less fit. Baseline QoL differed between the groups; the mean(s.d.) QLQ-C30 global health status score was 66.2(21.1) in patients who received primary endocrine therapy versus 77.1(17.8) among those who had surgery plus endocrine therapy. In the unmatched analysis, changes in QoL between 6 weeks and baseline were noted in several domains, but by 24 months most scores had returned to baseline levels. In the matched analysis, major surgery (mastectomy or axillary clearance) had a more pronounced adverse impact than primary endocrine therapy in several domains. CONCLUSION: Adverse effects on QoL are seen in the first few months after surgery, but by 24 months these have largely resolved. Women considering surgery should be informed of these effects.

Bridging the age gap in breast cancer: cluster randomized trial of two decision support interventions for older women with operable breast cancer on quality of life, survival, decision quality, and treatment choices.

BACKGROUND: Rates of surgery and adjuvant therapy for breast cancer vary widely between breast units. This may contribute to differences in survival. This cluster RCT evaluated the impact of decision support interventions (DESIs) for older women with breast cancer, to ascertain whether DESIs influenced quality of life, survival, decision quality, and treatment choice. METHODS: A multicentre cluster RCT compared the use of two DESIs against usual care in treatment decision-making in older women (aged at least ≥70 years) with breast cancer. Each DESI comprised an online algorithm, booklet, and brief decision aid to inform choices between surgery plus adjuvant endocrine therapy versus primary endocrine therapy, and adjuvant chemotherapy versus no chemotherapy. The primary outcome was quality of life. Secondary outcomes included decision quality measures, survival, and treatment choice. RESULTS: A total of 46 breast units were randomized (21 intervention, 25 usual care), recruiting 1339 women (670 intervention, 669 usual care). There was no significant difference in global quality of life at 6 months after the baseline assessment on intention-to-treat analysis (difference -0.20, 95 per cent confidence interval (C.I.) -2.69 to 2.29; P = 0.900). In women offered a choice of primary endocrine therapy versus surgery plus endocrine therapy, knowledge about treatments was greater in the intervention arm (94 versus 74 per cent; P = 0.003). Treatment choice was altered, with a primary endocrine therapy rate among women with oestrogen receptor-positive disease of 21.0 per cent in the intervention versus 15.4 per cent in usual-care sites (difference 5.5 (95 per cent C.I. 1.1 to 10.0) per cent; P = 0.029). The chemotherapy rate was 10.3 per cent at intervention versus 14.8 per cent at usual-care sites (difference -4.5 (C.I. -8.0 to 0) per cent; P = 0.013). Survival was similar in both arms. CONCLUSION: The use of DESIs in older women increases knowledge of breast cancer treatment options, facilitates shared decision-making, and alters treatment selection.

High maternal folic acid intake around conception alters mouse blastocyst lineage allocation and expression of key developmental regulatory genes.

Folate, a cofactor for the supply of one-carbon groups, is required by epigenetic processes to regulate cell lineage determination during development. The intake of folic acid (FA), the synthetic form of folate, has increased significantly over the past decade, but the effects of high periconceptional FA intake on cell lineage determination in the early embryo remains unknown. Here, we investigated the effect of maternal high FA (HFA) intake on blastocyst development and expression of key regulatory genes. C57BL/6 adult female mice were fed either Control diet (1 mg FA) for 4 weeks before conception and during the preimplantation period (Con-Con); Control diet for 4 weeks preconception, followed by HFA (5 mg FA) diet during preimplantation (Con-HFA); or HFA diet for 4 weeks preconception and during preimplantation (HFA-HFA). At E3.5, blastocyst cell number, protein, and mRNA expression were measured. In HFA-HFA blastocysts, trophectoderm cell numbers and expression of CDX2, Oct-4, and Nanog were reduced compared with Con-Con blastocysts; Con-HFA blastocysts showed lower CDX2 and Oct-4 expression than Con-Con blastocysts. These findings suggest periconceptional HFA intake induces changes in key regulators of embryo morphogenesis with potential implications for subsequent development.

Home Telemonitoring to Reduce Readmission of High-Risk Patients: a Modified Intention-to-Treat Randomized Clinical Trial.

BACKGROUND: Home telemonitoring has been used with discharged patients in an attempt to reduce 30-day readmissions with mixed results. OBJECTIVE: To assess whether home 30-day telemonitoring after discharge for patients at high risk of readmission would reduce readmissions or mortality. DESIGN: Prospective, randomized controlled trial. PATIENTS: We compared 30-day readmission rates and mortality for patients at high risk for readmission who received home telemonitoring versus standard care between November 1, 2014, and November 30, 2018, in 2 tertiary care hospitals. INTERVENTIONS: The intervention group received home-installed equipment to measure blood pressure, heart rate, pulse oximetry, weight if heart failure was present, and glucose if diabetes was present. Results were transmitted daily and reviewed by a nurse. Both groups received standard care. MAIN MEASURES: The primary outcome was a composite end point of hospital readmission or death within 30 days after discharge. The secondary outcome was an emergency department visit within 30 days after discharge. KEY RESULTS: A total of 1380 participants (mean [SD] age, 66 [14] years; 722 [52.3%] men and 658 [47.7%] women) participated in this study. Using a modified intention-to-treat analysis, the risk of readmission or death within 30 days among patients at high readmission risk was 23.7% (137/578) in the control group and 18.2% (87/477) in the telemonitoring group (absolute risk difference, - 5.5% [95% CI, - 10.4 to - 0.6%]; relative risk, 0.77 [95% CI, 0.61 to 0.98]; P = .03). Emergency department visits occurred within 30 days after discharge in 14.2% (81/570) of patients in the control group and 8.6% (40/464) of patients in the telemonitoring group (absolute risk difference, - 5.6% [95% CI, - 9.4 to - 1.8%]; relative risk, 0.61 [95% CI, 0.42 to 0.87]; P = .005). CONCLUSIONS: Thirty days of postdischarge telemonitoring may reduce readmissions of high-risk patients. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT02136186.

Use of Pharmacogenomics to Guide Proton Pump Inhibitor Therapy in Clinical Practice.

Prescribing the right medication, at the right dose, to the right patient is the goal of every physician. Pharmacogenomic information is an emerging tool that can be used to deliver precision medicine. In this review, we discuss the pharmacogenomics of available PPIs, racial differences of CYP2C19 and how PPI pharmacogenomics affects the treatment of common gastrointestinal diseases. We also provide practical guidance on when to order pharmacogenomic testing, which test to order, and how to modify treatment based on published guidelines.

Delirium occurrence and association with outcomes in hospitalized COVID-19 patients.

Delirium is reported to be one of the manifestations of coronavirus infectious disease 2019 (COVID-19) infection. COVID-19 hospitalized patients are at a higher risk of delirium. Pathophysiology behind the association of delirium and COVID-19 is uncertain. We analyzed the association of delirium occurrence with outcomes in hospitalized COVID-19 patients, across all age groups, at Mayo Clinic hospitals.A retrospective study of all hospitalized COVID-19 patients at Mayo Clinic between March 1, 2020 and December 31, 2020 was performed. Occurrence of delirium and outcomes of mortality, length of stay, readmission, and 30-day mortality after hospital discharge were measured. Chi-square test, student t-test, survival analysis, and logistic regression analysis were performed to measure and compare outcomes of delirium group adjusted for age, sex, Charlson comorbidity score, and COVID-19 severity with no-delirium group.A total of 4351 COVID-19 patients were included in the study. Delirium occurrence in the overall study population was noted to be 22.4%. The highest occurrence of delirium was also noted in patients with critical COVID-19 illness severity. A statistically significant OR 4.35 (3.27-5.83) for in-hospital mortality and an OR 4.54 (3.25-6.38) for 30-day mortality after discharge in the delirium group were noted. Increased hospital length of stay, 30-day readmission, and need for skilled nursing facility on discharge were noted in the delirium group. Delirium in hospitalized COVID-19 patients is a marker for increased mortality and morbidity. In this group, outcomes appear to be much worse when patients are older and have a critical severity of COVID-19 illness.

Older adults on involuntary hold status in the emergency department.

BACKGROUND: As the United States' population ages, the health care system will experience overall change. This study aims to identify factors in the older adult that may contribute to involuntary hold status in the ED. METHODS: This study is a retrospective review conducted at a suburban acute-care hospital ED of adult patients evaluated while on involuntary hold from January 1, 2014, through November 30, 2015. Older adults (patients born on or before 06/31/1964) were compared to younger adults (born on or after 07/01/1964) according to demographic and clinical variables including medical comorbidity, ED length of stay, reason for involuntary hold, psychiatric disorder, suicide attempt, substance use disorder, serum alcohol level, urine drug testing, medical comorbidity, violence in the ED, 30-day ED readmission, and 30-day mortality. RESULTS: Of 251 patients, 90 (35.9%) were older adults. The most common reason for involuntary hold in both cohorts was suicidal ideation. Medical comorbidities were more prevalent in older adults [60 (66.7%) vs. 64 (39.8%), P ≤.0001]. Older adults were less likely to report current drug abuse [31 (34.4%) vs. 77 (47.8%), P = .04]. The most commonly misused substance in both groups was alcohol; however, despite similar rates, blood alcohol levels (BAC) and urine drug screen (UDS) were performed less often in older adults. Cohorts were not significantly different with respect to sex, race, violence in the ED, psychiatric diagnosis, and ED LOS. CONCLUSIONS: Involuntary older adult patients present with medical comorbidities that impact mental health. In the ED, they are less likely report substance use, and drug screening may be underutilized. Medical needs make their care unique and may present challenges in transfer of care to inpatient psychiatric facilities.

Spiritual Care of Inpatients Focusing on Outcomes and the Role of Chaplaincy Services: A Systematic Review.

OBJECTIVE: To identify demographic trends associated with patient utilization and healthcare provider request for spiritual care services and to describe the impact of spiritual care on the quality of life (QoL), spiritual well-being (SWB) and level of satisfaction (SAT) of hospitalized patients. PATIENTS AND METHODS: A systematic search of Ovid MEDLINE, Embase, PsycINFO, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Scopus, was combined with review of relevant bibliographies. A total of 464 titles and abstracts were reviewed. Data were independently extracted by reviewers according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Data on the effects of spiritual interventions on QoL, SWB and SAT were extracted, along with demographic data reflecting chaplain services. The results of the studies are presented narratively and in a qualitative manner. RESULTS: Observational or experimental studies investigating chaplain utilization demographics (n = 12), patient satisfaction (n = 9) and QoL/SWB (n = 3) were included. Perceived severity of illness, average length of stay and older age were consistently found to be predictors of higher need for spiritual care. Receipt of spiritual care was correlated with increased patient and family satisfaction, independent of clinical outcome. Chaplain interventions were associated with improvement in perceived QoL and SWB. In spite of this, healthcare workers rarely attempt to explore the patient's or family's need for spiritual care, with the majority of chaplaincy consults occurring in the final day of the patient's life, potentially leading to a failure to meet the spiritual needs of non-terminal patients who have spiritual trauma related to their resolving illnesses. CONCLUSION: Attention to the spiritual needs of hospitalized patients is an essential yet often overlooked aspect of patient care. Chaplains serve as spiritual care specialists whose services can enhance the hospital experience, improve patient satisfaction and help to bridge potential gaps between the patient and medical providers.

The structure of ScC2 (X̃2A1): A combined Fourier transform microwave/millimeter-wave spectroscopic and computational study.

Pure rotational spectra of Sc13C2 (X̃2A1) and Sc12C13C (X̃2A') have been measured using Fourier transform microwave/millimeter-wave methods. These molecules were synthesized in a DC discharge from the reaction of scandium vapor, produced via laser ablation, with 13CH4 or 13CH4/12CH4, diluted in argon. The NKa,Kc = 10,1 → 00,0, 20,2 → 10,1, 30,3 → 20,2, and 40,4 → 30,3 transitions in the frequency range of 14 GHz-61 GHz were observed for both species, each exhibiting hyperfine splittings due to the nuclear spins of 13C (I = 1/2) and/or Sc (I = 7/2). These data have been analyzed with an asymmetric top Hamiltonian, and rotational, spin-rotation, and hyperfine parameters have been determined for Sc13C2 and Sc12C13C. In addition, a quartic force field was calculated for ScC2 and its isotopologues using a highly accurate coupled cluster-based composite method, incorporating complete basis set extrapolation, scalar relativistic corrections, outer core and inner core electron correlation, and higher-order valence correlation effects. The agreement between experimental and computed rotational constants, including the effective constant (B + C), is ∼0.5% for all three isotopologues. This remarkable agreement suggests promise in predicting rotational spectra of new transition metal-carbon bearing molecules. In combination with previous work on Sc12C2, an accurate structure for ScC2 has been established using combined experimental (B, C) and theoretical (A) rotational constants. The radical is cyclic (or T-shaped) with r(Sc-C) = 2.048(2) Å, r(C-C) = 1.272(2) Å, and ∠(C-Sc-C) = 36.2(1)°. The experimental and theoretical results also suggest that ScC2 contains a C2 - moiety and is largely ionic.

Involuntary patient length-of-stay at a suburban emergency department.

BACKGROUND: Patients who may be a danger to themselves or others often are placed on involuntary hold status in the Emergency Department (ED). Our primary objective was to determine if there are demographic and/or clinical variables of involuntary hold patients which were associated with an increased ED LOS. METHODS: Records of ED patients evaluated while on involuntary hold from January 1, 2014 through November 30, 2015 at a suburban acute-care hospital ED were reviewed. Data collected included demographics information, LOS, suicidal or homicidal ideation, suicide attempt, blood alcohol concentration (BAC), urine drug test (UDT), psychiatric disorder, substance use, medical illness, violence in the ED, and hospital admission. Linear regression based on the log of LOS was used to identify factors associated with increased LOS. RESULTS: Two-hundred and fifty-one patients were included in the study. ED LOS (median) was 6 h (1, 49). Linear regression analysis showed increased LOS was associated with BAC (p = 0.05), urine drug test (UDT) (p = 0.05) and UDT positive for barbiturates (p = 0.01). There was no significant difference in ED LOS with respect to age, gender, housing, psychiatric diagnosis, suicidal or homicidal ideation, suicide attempt, violence, medical diagnosis, or admission status. CONCLUSIONS: Involuntary hold patients had an increased ED LOS associated with alcohol use, urine drug test screening, and barbiturate use. Protocol development to help stream-line ED evaluation of alcohol and drug use may improve ED LOS in this patient population.

Bald eagle mercury exposure varies with region and site elevation in New York, USA.

Freshwater fish in several regions of New York State (NYS) are known to contain concentrations of mercury (Hg) associated with negative health effects in wildlife and humans. We collected blood and breast feathers from bald eagle (Haliaeetus leucocephalus) nestlings throughout NYS, with an emphasis on the Catskill region to determine their exposure to Hg. We assessed whether habitat type (lake or river), region (Delaware-Catskill region vs. rest of NY) or sample site elevation influenced Hg concentrations in bald eagle breast feathers using ANCOVA. The model was significant and accounted for 41% of the variability in log10 breast feather Hg concentrations. Mercury concentrations in nestling breast feathers were significantly greater in the Delaware-Catskill Region (geometric mean: 14.5 µg/g dw) than in the rest of NY (7.4 µg/g, dw), and greater at nests located at higher elevations. Habitat type (river vs. lake) did not have a significant influence on breast feather Hg concentrations. Geometric mean blood Hg concentrations were significantly greater in Catskill nestlings (0.78 µg/g ww) than in those from the rest of NY (0.32 µg/g). Mercury concentrations in nestling breast feathers and especially blood samples from the Delaware-Catskill region were generally greater than those reported for most populations sampled elsewhere, including areas associated with significant Hg pollution problems. Bald eagles can serve as valuable Hg bioindicators in aquatic ecosystems of NYS, particularly given their broad statewide distribution and their tendency to nest across all major watersheds and different habitat types.

A synthesis of patterns of environmental mercury inputs, exposure and effects in New York State.

Mercury (Hg) pollution is an environmental problem that adversely affects human and ecosystem health at local, regional, and global scales-including within New York State. More than two-thirds of the Hg currently released to the environment originates, either directly or indirectly, from human activities. Since the early 1800s, global atmospheric Hg concentrations have increased by three- to eight-fold over natural levels. In the U.S., atmospheric emissions and point-source releases to waterways increased following industrialization into the mid-1980s. Since then, water discharges have largely been curtailed. As a result, Hg emissions, atmospheric concentrations, and deposition over the past few decades have declined across the eastern U.S. Despite these decreases, Hg pollution persists. To inform policy efforts and to advance public understanding, the New York State Energy Research and Development Authority (NYSERDA) sponsored a scientific synthesis of information on Hg in New York State. This effort includes 23 papers focused on Hg in atmospheric deposition, water, fish, and wildlife published in Ecotoxicology. New York State experiences Hg contamination largely due to atmospheric deposition. Some landscapes are inherently sensitive to Hg inputs driven by the transport of inorganic Hg to zones of methylation, the conversion of inorganic Hg to methylmercury, and the bioaccumulation and biomagnification along food webs. Mercury concentrations exceed human and ecological risk thresholds in many areas of New York State, particularly the Adirondacks, Catskills, and parts of Long Island. Mercury concentrations in some biota have declined in the Eastern Great Lakes Lowlands and the Northeastern Highlands over the last four decades, concurrent with decreases in water releases and air emissions from regional and U.S. sources. However, widespread changes have not occurred in other ecoregions of New York State. While the timing and magnitude of the response of Hg levels in biota varies, policies expected to further diminish Hg emissions should continue to decrease Hg concentrations in food webs, yielding benefits to the fish, wildlife, and people of New York State. Anticipated improvements in the Hg status of aquatic ecosystems are likely to be greatest for inland surface waters and should be roughly proportional to declines in atmospheric Hg deposition. Efforts that advance recovery from Hg pollution in recent years have yielded significant progress, but Hg remains a pollutant of concern. Indeed, due to this extensive compilation of Hg observations in biota, it appears that the extent and intensity of the contamination on the New York landscape and waterscape is greater than previously recognized. Understanding the extent of Hg contamination and recovery following decreases in atmospheric Hg deposition will require further study, underscoring the need to continue existing monitoring efforts.

Associations of circulating cell-free microRNA with vasculopathy and vascular events in systemic lupus erythematosus patients.

OBJECTIVE: Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with a high risk of atherosclerosis and cardiovascular disease (CVD). MicroRNAs (miRNAs) are small non-coding RNAs that modulate protein translation, and dysregulation is seen in autoimmunity, atherosclerosis, and CVD. We investigate associations between circulating miRNAs and markers of atherosclerosis in SLE patients. METHOD: A group (n = 121) of well-characterized SLE patients were screened for atherosclerosis by cardiac computed tomography and carotid ultrasound. RNA was purified from plasma and 46 specific miRNAs were determined using quantitative real-time polymerase chain reaction. RESULTS: Forty-one miRNAs were consistently detected. Fifty out of 118 available SLE patients had atherosclerosis. A profile consisting of three miRNAs (decreased miR-125b, miR-101, miR-375) was indicative of atherosclerosis. Multivariate logistic regression identified eight clinical manifestations associated with atherosclerotic outcome. The full classification profile showed a specificity of 88% and a sensitivity of 86%. Hierarchical clustering identified an eight-miRNA profile that differentiated a subgroup of SLE patients (n = 16) who had significantly increased venous thrombotic events (p = 0.045), a higher prevalence of ß2-glycoprotein I antibodies (p = 0.029), and an increased prevalence of thrombocytopenia (p = 0.028). CONCLUSION: In this cross-sectional study, the circulating miRNA profile distinguished SLE patients with atherosclerosis from those without. Furthermore, an eight-miRNA signature was associated with thrombocytopenia, venous thrombotic events, and ß2-glycoprotein I antibodies in SLE patients. Prospective studies are needed to confirm the findings and to establish the precise role of circulating miRNA profiling in the evaluation of atherosclerosis in SLE.

The pure rotational spectrum of the ZnBr radical (X2Σ+): Trends in the zinc halide series.

The pure rotational spectrum of ZnBr (X2Σ+) has been recorded in the frequency range 259-310 GHz using millimeter-wave direct absorption techniques. This study is the first quantitative spectroscopic investigation of this free radical. ZnBr was synthesized in a DC discharge by the reaction of zinc vapor in argon with one of three reagents: BrCH3, Br2CH2, or Br2. Eight rotational transitions were measured for six isotopologues (64Zn79Br, 64Zn81Br, 66Zn79Br, 66Zn81Br, 68Zn79Br, and 68Zn81Br), all of which exhibited spin-rotation interactions. Furthermore, transitions originating in the v = 1 through 3 excited vibrational states were obtained for certain isotopologues. Five rotational transitions were also recorded for 67Zn79Br, in which hyperfine splittings were observed arising from the 67Zn nucleus (I = 5/2). The spectra were analyzed using a Hund's case (bßJ) Hamiltonian, and rotational, spin-rotation, and 67Zn magnetic hyperfine constants were determined. Equilibrium parameters were also derived for the 64Zn79Br, 64Zn81Br, 66Zn79Br, and 66Zn81Br isotopologues, including the vibrational constant, ωe = 286 cm-1. The equilibrium bond length was derived to be re = 2.268 48(90) Å. Analysis of the 67Zn hyperfine parameters suggest a decrease in ionic character in ZnBr from the other known zinc halides, ZnF and ZnCl.

Canine-Assisted Therapy in Hospitalized Patients Awaiting Heart Transplantation.

OBJECTIVES: Patients awaiting heart transplantation can be listed for prolonged periods of time and, as a result, the prevalence of anxiety and depression is high. Our study evaluates the feasibility of canine-assisted therapy (CAT) in this population. METHODS: A prospective, multicenter study was performed on all status 1a patients admitted during a 12-month period to await transplantation. Patients were asked to complete the Generalized Anxiety Disorder 7-item scale and the Patient Health Questionnaire-9 at baseline, week 2, and week 6, and the Perceived Stress Scale at baseline and week 4. At the conclusion of the study, patients completed a questionnaire assessing the overall efficacy of CAT. RESULTS: Baseline measures demonstrated high levels of anxiety, depression, and stress. The complete Generalized Anxiety Disorder 7-item scale (average score 10.9 vs 8; P = 0.14) and the Patient Health Questionnaire-9 (average score 12.3 vs 9.5; P = 0.057) scores decreased from baseline to week 6 and the Perceived Stress Scale (average score 29.8 vs 27; P = 0.16) decreased from baseline to week 4 with trends toward significance. All of the patients perceived CAT as improving the overall quality of hospitalization, would recommend CAT to other patients, and would elect for CAT during subsequent admissions. No infectious concerns were reported. CONCLUSIONS: Anxiety, stress, and depression are prevalent among 1a heart transplantation candidates, and CAT is a welcomed adjunct to the usual medical care in this population.

Patients on Involuntary Hold Status in the Emergency Department.

OBJECTIVES: Patients requiring involuntary holds are frequently seen in the emergency department (ED). Much of what is known comes from studies of patients at urban academic centers. Our aim was to describe the demographic and clinical characteristics of patients who were evaluated while on involuntary status at a suburban ED. METHODS: The medical records of patients seen in the ED requiring involuntary hold status between January 1, 2014 and November 30, 2015 were reviewed. Demographic and clinical variables including medical and psychiatric comorbidity were collected. A subanalysis was performed comparing patients who attempted suicide with all other involuntary patients. RESULTS: Two hundred fifty-one patient records were reviewed; 215 patients (85.3%) had psychiatric disorders-depression was the most common (57%)-and 108 patients (43%) had substance use disorders. Only 13 patients (5.2%) had neither a psychiatric disorder nor a history of substance use. Twenty-two patients (8.8%) were violent in the ED. Thirteen patients (5.2%) were readmitted, and 1 patient died within 30 days of discharge from the ED. One hundred twenty-four patients (49.4%) had medical disorders. Suicidal ideation was the most common reason for involuntary hold (n = 185, 73.7%); 63 patients (25.1%) attempted suicide. Compared with other involuntary patients, the patients who attempted suicide were less likely to use opiates (odds ratio 0.27, 95% confidence interval 0.08-0.94, P = 0.04) and to have medical disorders (odds ratio 0.52, 95% confidence interval 0.28-0.98, P = 0.04). CONCLUSIONS: Patients in this study differed from those in urban centers with respect to sex and psychiatric disorder; however, substance misuse was common in both settings. Suicidal ideation including suicide attempt was the most common reason for involuntary status. Patients who attempted suicide were similar to other patients on involuntary hold with respect to demographic and clinical variables.

Patients Threatening Harm to Others Evaluated in the Emergency Department under the Florida Involuntary Hold Act (Baker Act).

OBJECTIVES: This study describes the specific threats of harm to others that led to the use of the Baker Act, the Florida involuntary hold act for emergency department (ED) evaluations. The study also summarizes patient demographics, concomitant psychiatric diagnoses, and emergent medical problems. METHODS: This is a retrospective review of 251 patients evaluated while on involuntary hold from January 1, 2014 through November 30, 2015 at a suburban acute care hospital ED. The data that were collected included demographic information, length of stay, reason for the involuntary hold, psychiatric disorder, substance use, medical illness, and violence in the ED. The context of the homicidal threat also was collected. RESULTS: We found that 13 patients (5.2%) were homicidal. Three patients had homicidal ideations alone, whereas 10 made homicidal threats toward others. Of the 10 making homicidal threats, 7 named a specific person to harm. Ten of the 13 homicidal patients (76.9%) also were suicidal. Eleven patients (84.6%) had a psychiatric disorder: 9 patients (69.2%) had a depressive disorder and 8 patients (61.5%) had a substance use disorder. Eight patients had active medical problems that required intervention in the ED. CONCLUSIONS: We found that three-fourths of patients expressing homicidal threats also were suicidal. The majority of patients making threats of harm had a specific plan of action to carry out the threat. It is important to screen any patient making homicidal threats for suicidal ideation. If present, there is a need to implement immediate management appropriate to the level of the suicidal threat, for the safety of the patient. Eighty-five percent of patients making a homicidal threat had a previously documented psychiatric disorder, the most common being a depressive disorder. This finding differs from previous studies in which psychosis predominated. More than 60% of homicidal patients had an unrelated medical disorder requiring intervention. It is important not to overlook these medical disorders while focusing on the psychiatric needs of the patient; most of our homicidal patients proved to be cooperative in the ED setting.
