The Impact of Loneliness and Social Anxiety on Casual Social Contacts.

Introduction In the wake of the COVID-19 pandemic, loneliness and social isolation have become major public health crises. Loneliness has reached epidemic levels and negatively impacts both health and quality of life. "Casual contacts" is a developing line of research that may hold promise in stemming the current crisis.

Lyssa excreta: Defining parameters for fecal samples as a rabies virus surveillance method.

It is not possible to systematically screen the environment for rabies virus (RABV) using current approaches. We sought to determine under what conditions RABV is detectable from feces and other accessible samples from infected wildlife to broaden the number of biological samples that could be used to test for RABV. We employed a recently-developed quantitative RT-PCR assay called the "LN34 panlyssavirus real-time RT-PCR assay", which is highly sensitive and specific for all variants of RABV.

Endangered Nectar-Feeding Bat Detected by Environmental DNA on Flowers.

(the Mexican long-nosed bat) is an endangered nectar-feeding bat species that follows "nectar corridors" as it migrates from Mexico to the southwestern United States. Locating these nectar corridors is key to their conservation and may be possible using environmental DNA (eDNA) from these bats. Hence, we developed and tested DNA metabarcoding and qPCR eDNA assays to determine whether could be detected by sampling the agave flowers on which it feeds.

A randomized controlled trial of a gender-focused addiction model versus 12-step facilitation for women veterans.

Background And Objectives: Substance use disorder (SUD) has increased among women, including military veterans, yet SUD treatment was historically designed for males. This randomized controlled trial compared 12 individual sessions of a gender-focused SUD recovery model, A Woman's Path to Recovery (WPR) to an evidence-based, non-gender-focused SUD model, 12-Step Facilitation (TSF) for 66 women veterans with current severe SUD.

Methods: The primary outcome was substance use; secondary outcomes were associated problems (e.

Gambling-related cognitive distortions predict level of function among US veterans seeking treatment for gambling disorders.

Background And Objectives: Gambling Disorder (GD) is characterized by recurrent gambling behavior that is associated with significant impairment and distress, high psychiatric comorbidities, and high functional disability. The military veteran population appears particularly susceptible to developing the disorder, but relatively little has been studied among this population. The purpose of the present study is to investigate the clinical psychopathologies and comorbidities of veterans seeking treatment for problem gambling and how problem gambling may impact functioning.

Implementation of a tobacco-free regulation in substance use disorder treatment facilities.

We assessed the impact of a statewide tobacco-free services regulation on facility administrators' attitudes and the integration of tobacco dependence treatment into substance use disorder services. We surveyed substance use disorder treatment facility administrators in New York before (n = 285) and after (n = 205) tobacco-free services regulation implementation about their attitudes, their perceptions of staff and patient attitudes, and the facilities' services. We analyzed data on admissions and tobacco treatment pharmacotherapy administration.

Efficacy of bupropion alone and in combination with nicotine gum.

In this double-blind, placebo-controlled smoking cessation treatment study, 608 participants were randomly assigned to receive active bupropion and active 4-mg gum (AA, n = 228), active bupropion and placebo gum (AP, n = 224), or placebo bupropion and placebo gum (PP, n = 156). Relative to the PP group, the AA and AP groups were each significantly more likely to be abstinent at 1 week, end of treatment, and 6 months but not at 12 months postquit. After the first week postquit there were no differences in abstinence rates between the AA and AP groups.

Regional differences in alcohol use among U. S. military personnel.

Objective: The purpose of this study was to examine differences in heavy alcohol use and alcohol-related negative effects among U.S. military personnel stationed in different world regions and to examine factors that may account for regional differences.

A multiple motives approach to tobacco dependence: the Wisconsin Inventory of Smoking Dependence Motives (WISDM-68).

The dependence construct fills an important explanatory role in motivational accounts of smoking and relapse. Frequently used measures of dependence are either atheoretical or grounded in a unidimensional model of physical dependence. This research creates a multidimensional measure of dependence that is based on theoretically grounded motives for drug use and is intended to reflect mechanisms underlying dependence.

Lifetime use of mental health and substance abuse treatment services by incarcerated women felons.

Objective: This study examined the lifetime use of alcohol, drug, and mental health treatment services by recently incarcerated women prison inmates.

Methods: A total of 805 women entering a North Carolina prison for new felony charges in 1991 and 1992 were interviewed in person shortly after incarceration. The women were assessed for psychiatric disorders and lifetime use of substance abuse and mental health treatment services.

Clinical care of gambling disorders: training, experience, and competence among VHA psychologists.

Problem gambling is a common, highly destructive disorder which is often overlooked by clinicians. Levels of clinical training, clinical experience, and professional competence for providing clinical services for problem gambling were examined in a survey of 181 clinical psychologists working in the Veterans Healthcare Administration (VHA). The results suggest that the majority of clinical psychologists have little or no formal training and little or no past or current clinical experience in the treatment of disordered gambling, nor do they see themselves as competent to evaluate or treat patients with disordered gambling.

Specialty mental health care improves patients' outcomes: findings from a nationwide program to monitor the quality of care for patients with substance use disorders.

Objective: To describe the implementation of a nationwide program to monitor the quality of treatment for substance use disorders in the Department of Veterans Affairs, and to examine how the provision of outpatient mental health care, and the duration and intensity of care, relate to patients' outcomes.

Method: Clinicians completed a baseline Addiction Severity Index (ASI) on more than 34,000 patients with substance use disorders; more than 21,000 (63%) were reassessed with the ASI an average of 12 months later. Nationwide health service utilization databases were used to obtain information about patients' diagnoses and their use of services during an index episode of care.

Relationship between climate and psychiatric inpatient length of stay in Veterans Health Administration hospitals.

Objective: The study examined whether climate has an impact on inpatient psychiatric length of stay in Veterans Health Administration hospitals (VHA).

Method: Data from the National Weather Service for eight climate variables for the locations of 134 VHA hospitals nationwide were factor analyzed, resulting in two climate factors representing temperature and precipitation. Factor scores were correlated with psychiatric mean lengths of stay from 1994 to 1998 for 99 VHA hospitals with inpatient psychiatric services and for the 22 VHA regional divisions (Veterans Integrated Service Networks).

HIV-risk behaviors associated with homelessness characteristics in youth.

Purpose: To examine characteristics of youth homelessness associated with engaging in risk behaviors for human immunodeficiency virus (HIV).

Methods: The sample included 288 currently homeless or runaway Washington, DC youth aged 14-21 years. Measures were self-reported homelessness characteristics, unsafe sexual behavior, injection drug use, and background characteristics.

Development of psychiatric comorbidity with substance abuse in adolescents: effects of timing and sex.

Examined the impact of childhood psychiatric disorders on the prevalence and timing of substance use and abuse and tested for sex differences. A representative population sample of 1,420 children, ages 9, 11, and 13 at intake, were interviewed annually. American Indians and youth with behavioral problems were oversampled; data were weighted back to population levels for analysis.

Social network characteristics associated with risky behaviors among runaway and homeless youth.

Runaway and homeless youth are at high risk for substance abuse and unsafe sexual behavior. Our study describes the personal social networks of these youth and examines network characteristics associated with risky behaviors. In 1995 and 1996, we interviewed a purposive sample of youth aged 14 through 21 who were living in Washington, DC and were identified on the streets or through shelters or other service agencies (N = 327).

Processing and recognition of facial affect in schizophrenia.

A deficit in the recognition of facial affect has been well documented in people with schizophrenia. Our 1995 research with normal subjects showed that hemispheric bias for processing facial affect is related to accuracy of recognition of facial affect. We tested whether this relationship holds in a sample of 25 people with schizophrenia who completed tasks of identification of facial affect and chimeric facial affect.

Remission and relapse in schizophrenia: the Madras Longitudinal Study.

This paper uses monthly symptom data on 90 first-onset schizophrenics in Madras, India, to characterize, in a continuous manner, the course of remission and relapse. Remission from the first episode occurs in about 6 months and in about 3 months for later episodes. Syndromes from the Present State Exam, assessed at the first episode, predict differentially to early and later parts of the course.

Affect identification bias demonstrated with individual chimeric faces.

The current study extends previous findings of a left visual-field bias in chimeric face tasks, by using a new procedure which incorporates chimeric stimuli depicting both positive and negative target affects and requires the identification of affect in individually presented faces. This new procedure is more representative of the types of judgements made in daily social interaction. Results with this new procedure are consistent with previous findings, indicating a significant left visual-field bias for both positive and negative affects in the majority of subjects.

Development of substance use and psychiatric comorbidity in an epidemiologic study of white and American Indian young adolescents the Great Smoky Mountains Study.

The progression of substance use and the patterns of comorbidity of substance use and psychiatric disorders are explored prospectively in young adolescents enrolled in the Great Smoky Mountains Study. This study is an epidemiologic study of white and American Indian youths living in rural Southern Appalachia. Results from this study indicate that alcohol use without permission predicts subsequent use of illicit drugs and regular tobacco use.

Ziskind-Somerfeld Research Award 1996. Medial and superior temporal gyral volumes and cerebral asymmetry in schizophrenia versus bipolar disorder.

Prior magnetic resonance imaging (MRI) studies report both medial and lateral cortical temporal changes and disturbed temporal lobe asymmetries in schizophrenic patients compared with healthy controls. The specificity of temporal lobe (TL) changes in schizophrenia is unknown. We determined the occurrence and specificity of these TL changes.

Decreased regional cortical gray matter volume in schizophrenia.

Objective: The authors hypothesized that cortical gray matter volume reduction in schizophrenia is greatest in the heteromodal association cortex. This area comprises a highly integrated, reciprocally interconnected system that coordinates higher order cortical functions.

Method: Total brain and regional gray matter volumes were calculated in 46 schizophrenic patients and 60 age and sex-matched comparison subjects by using magnetic resonance images.
