Alkyne-Functionalized Platinum Chalcogenide (S, Se) Nanoparticles.

Metal chalcogenide nanoparticles play a vital role in a wide range of applications and are typically stabilized by organic derivatives containing thiol, amine, or carboxyl moieties, where the nonconjugated particle-ligand interfaces limit the electronic interactions between the inorganic cores and organic ligands. Herein, a wet-chemistry method is developed for the facile preparation of stable platinum chalcogenide (S, Se) nanoparticles capped with acetylene derivatives (e.g.

Characteristics of International Assaultive Psychiatric Patients: Review of Published Findings, 2017-2022.

Since the 1960s, empirical research has focused on a better understanding of the characteristics of assaultive psychiatric patients. International research from 1960 to 2017 indicated that male and female patients with schizophrenia and substance use disorder presented the greatest risk for assault with nursing personnel being at higher risk. This present review of studies sought to assess the latest research findings on assaultive patients for the most recent five-year period, 2017-2022.

Public Works Employees and Posttruamatic Stress Disorder: an At-Risk Population.

Although not widely known, public works employees in the United States were designated as emergency providers during critical incidents in 2003 and have provided these public works services, when activated. These public works employees may be either employees of a specific government entity or, more recently, privately contracted employees who provide similar services for a government entity. First responders working critical incidents are at risk for psychological trauma and posttraumatic stress disorder (PTSD).

Characteristics of International Staff Victims of Psychiatric Patient Assaults: Review of Published Findings, 2017-2022.

Psychiatric patient assaults on staff are a worldwide occupational hazard for health care staff that results in medical injury, human suffering, and dollar cost expense. International research through 2000-2017 documented the continued frequency of these assaults and a continuing high risk for nursing personnel. This present paper reviewed the international published literature on staff victims of patient assaults during the next five-year period of 2017-2022.

A Naïve Population of European Oyster Ostrea edulis with Reduced Susceptibility to the Pathogen Bonamia ostreae: Are S-Strategy Life Traits Providing Protection?

European populations of the native flat oyster, Ostrea edulis, have been heavily depleted by two protozoan parasites, Marteila refringens and Bonamia ostreae, with mortalities of up to 90% reported in naïve populations. However, in studies carried out over a 10-year period, researching the parasite-host relationship of B. ostreae and O.

International Review of Precipitants to Patient Assaults on Staff, 2013-2017.

In studying psychiatric patient assaults, assessing the person x event x environment interaction is important in enhancing safety and ensuring quality care. Precipitants to patient assaults have traditionally received less attention than the patient characteristics of such assaults. Reviews of inpatient precipitants from 1960 to 2012 noted acute psychosis, denial of services, and substance abuse as commonly occurring precipitants.

Characteristics of International Assaultive Psychiatric Patients: Review of Published Findings, 2013-2017.

Since the 1960s, empirical research has worked toward a better understanding of the characteristics of assaultive psychiatric patients. International research through 2012 indicated that male and female patients with schizophrenia and other diagnoses presented the greatest risk for assault. This present review of studies that presented raw assault sought to assess the latest research findings on assaultive patients for the most recent 5 year period, 2013-2017.

Characteristics of International Staff Victims of Psychiatric Patient Assaults: Review of Published Findings, 2013-2017.

Psychiatric patient assaults on staff are a worldwide occupational hazard for health care staff that results in human suffering and dollar cost expense. International research through 2012 documented the frequency of these assaults and a continuing high risk for nursing personnel. This present paper reviewed the international published literature on staff victims of patient assaults during the next five year period of 2013-2017.

Investigating the significance of the role of Ostrea edulis larvae in the transmission and transfer of Bonamia ostreae.

In this study, the ability of oyster larvae, brooded in the pallial cavity of the parent oyster, to become infected in the pallial fluid, which is influenced by the brooding oyster and surrounding environment, was investigated. Larvae were collected over three summers from three areas around Ireland. Samples were screened for the presence of Bonamia ostreae DNA using PCR analysis.

International precipitants to psychiatric patient assaults in community settings: review of published findings, 2000-2012.

In studying psychiatric patient assaults, assessing the person × event × environment interaction is important in enhancing safety and ensuring quality care. Precipitants to patient assaults have traditionally received less attention than the characteristics of such assaults. A recent review of inpatient precipitants noted acute psychosis, denial of services, and substance abuse as common precipitants in these settings.

Characteristics of international staff victims of psychiatric patient assaults: review of published findings, 2000-2012.

Psychiatric patient assaults on staff are a worldwide occupational hazard that results in human suffering and dollar cost expense. International research in the 1990s documented the frequent occurrence of these assaults. This present paper reviewed the published, international literature on staff victim assaults during the first decade of the new century.

Thirty-year history of Irish (Rossmore) Ostrea edulis selectively bred for disease resistance to Bonamia ostreae.

The protistan pathogen Bonamia ostreae was first detected in Ostrea edulis at Rossmore, Cork Harbour, on the south coast of Ireland in 1987. A selective breeding programme commenced in 1988 by Atlantic Shellfish Ltd. to produce B.

Interlaboratory variability in screening for Bonamia ostreae, a protistan parasite of the European flat oyster Ostrea edulis.

The spread of the protozoan parasite Bonamia ostreae is of major concern to the European flat oyster Ostrea edulis industry. Many studies have looked at the sensitivity of individual methods available to screen for B. ostreae, but in this study, 3 separate laboratories examined 4 methods of diagnosis currently used routinely in laboratories: heart imprints, histology, polymerase chain reaction (PCR) and in situ hybridisation (ISH).

Characteristics of American assaultive psychiatric patients: review of published findings, 2000-2012.

Previous reviews of the literature from 1976 to 2000 documented two categories of assaultive psychiatric patients: (1) male patients with schizophrenic illness and histories of violence toward others and substance use disorder and (2) male/female patients with personality disorders and histories of violence toward others, personal victimization, and substance use. The present study reviewed the published findings on American assaultive patients from 2000 to 2012. The present findings partially supported the earlier findings in that patients with schizophrenic illness continued to present the greatest risk for assault.

Characteristics of international assaultive psychiatric patients: review of published findings, 2000-2012.

In international reviews of psychiatric inpatient violence, one study of all types of patient violence found hostility, involuntary admission, and longer hospital stays associated with violence. A second study of comparison-group papers of patient assaults found younger males with schizophrenia, past violence, and substance abuse assaultive. The present review of raw assault data studies assessed characteristics of assaultive patients worldwide.

Coping in an intermittent swim stress paradigm compromises natural killer cell activity in rats.

The effects of intermittent swim stress and stressor controllability on natural killer cell activity (NKCA) was examined. Significant decreases in splenic NKCA were observed immediately post-stress, but only when the stress was controllable. Although decreased NKCA was also observed in yoked rats subjected to the same stressor, it failed to attain statistical significance.

Time of psychiatric patient assaults: twenty-year analysis of the Assaulted Staff Action Program (ASAP).

Apparent random acts of violence viewed in the aggregate appear to occur in fairly exacting temporal patterns. This is true of rape, street assaults, and domestic violence, among other acts of violence. Patient assaults on staff as acts of violence should also follow a temporal pattern.

B-type natriuretic peptide testing and the accuracy of heart failure diagnosis in the emergency department.

Background: It is often difficult to diagnose heart failure (HF) accurately in patients presenting with dyspnea to the emergency department (ED). This study assessed whether B-type natriuretic peptide (BNP) testing in these patients improved the accuracy of HF diagnosis.

Methods And Results: Patients presenting to the Alfred and the Northern Hospital EDs with a chief complaint of dyspnea were enrolled prospectively from August 2005 to April 2007.

B-type natriuretic peptide testing, clinical outcomes, and health services use in emergency department patients with dyspnea: a randomized trial.

Background: B-type natriuretic peptide (BNP) is used to diagnose heart failure, but the effects of using the test on all dyspneic patients is uncertain.

Objective: To assess whether BNP testing alters clinical outcomes and health services use of acutely dyspneic patients.

Design: Randomized, single-blind study.

Analysis of randomized controlled trials on the effect of magnitude of heart rate reduction on clinical outcomes in patients with systolic chronic heart failure receiving beta-blockers.

Beta blockers improve cardiac function and prolong survival in patients with systolic chronic heart failure (CHF). However, the exact mechanisms underlying these benefits are uncertain. Specifically, it is unclear whether a close relation exists between heart rate (HR) reduction and clinical outcomes with these agents.

Time of psychiatric patient assaults: fifteen-year analysis of the Assaulted Staff Action Program (ASAP).

An emerging literature on human-perpetrated violence suggests that seemingly apparent random acts of violence may indeed have important embedded temporal patterns. This study reviews this literature and presents the temporal findings of a fifteen-year study of patient assaults on staff in health care settings. Temporal patterns were observed for the variables of season, days of month, and shift.

Elderly patient assaults: empirical data from the Assaulted Staff Action Program (ASAP) with risk management implications for EMS personnel.

Some elderly patients may become violent in the course of receiving health care services. This paper reviews the largely cross-sectional research on elder assaultive patients in health care settings and patient assaults, including those by the elderly, in EMS services. Data on the assault characteristics of elderly patients are presented from a 15-year, retrospective, longitudinal study of the Assaulted Staff Action Program (ASAP).

Endocrine and immunological correlates of behaviorally identified swim stress resilient and vulnerable rats.

Animal models of stress-induced depression have identified a bimodal reactivity to stress, namely 'resilience' and 'vulnerability.' Possible corresponding differences in endocrine and immunological responses between these groups have not been delineated. Male Sprague-Dawley rats were divided into three groups: stress (n=25), confined controls (n=7), and home cage controls (n=7).

Leukocyte origin and profile in follicular aspirates at oocyte retrieval.

Background: Follicular aspirates represent a snapshot in time of conditions within the follicle at oocyte retrieval in women undergoing in vitro fertilization and embryo transfer. This clinical material has been much investigated and yet its cellular composition remains unclear. In this study we investigated the origin and profile of leukocytes found within follicular aspirates.

Alleles and haplotypes of tumor necrosis factor (TNF) alpha and beta genes in three ethnic populations of Sulawesi Indonesia.

Polymorphic variation in two cytokine genes, tumor necrosis factor (TNF) -alpha and -beta, was examined in three ethnic groups, the Bugis, the Makassans, and the Torajans, who inhabit Sulawesi, a large island in the Indonesian archipelago, and formerly a Dutch colony. TNF-alpha and -beta are key molecules in immune responses to infection, and both have been implicated in the pathogenesis and clinical manifestations of parasitic diseases. Several polymorphic variants with the potential to affect cytokine levels in autoimmune diseases and parasitic and bacterial infection have been reported.
