Determinants of home health visit length: results of a multisite prospective study.

Objectives: The authors (1) compare visit length across four categories of skilled nursing home health visits which reflect recent changes in home health casemix-AIDS-related, hospice/terminal (HT), intravenous (IV) therapy, and maternal and child health (MCH)-with general adult medical/surgical (MS) visits and (2) identify factors influencing visit length.

Methods: The study sites were 12 nonproprietary Massachusetts home health agencies (HHAs). Staff nurses collected data concurrently on a sample of visits they provided between December 1, 1992 and November 30, 1993.

Iliac artery stenosis measurements: comparison of two-dimensional time-of-flight and three-dimensional dynamic gadolinium-enhanced MR angiography.

Objective: We compared our ability to make iliac artery measurements on two-dimensional (2D) time-of-flight (TOF) and three-dimensional dynamic gadolinium-enhanced MR angiography with conventional angiography.

Subjects And Methods: Fifteen patients with lower extremity vascular disease underwent pelvic MR angiography. Parameters of the cardiac-gated axial 2D TOF sequence included a TR/TE of 24/7 msec and a 50 degrees flip angle.

Developing psychodynamic group treatment methods for aggressive male inpatients.

Group psychotherapy is one intervention that can be used for aggressive male inpatients. This paper reports relevant literature and clinical applications for conducting a psychodynamic psychotherapy group designed to help patients (a) identify, understand, and deal with underlying problems resulting in aggressive behavior; (b) improve interpersonal relationships; and (c) find more appropriate ways of expressing feelings, particularly those associated with aggressive behavior. The review of literature focuses on therapeutic approaches for dealing with aggressive feelings in group therapy; men's issues in group psychotherapy, including stages of group development for men and the expression of aggression; and the outcome of aggressive behavior in response to group therapy.

The relationship of behavioral cues to assaultive behavior.

The purpose of this 2-year, case control study was to determine whether differentiation between assaultive and nonassaultive patients can be made based on behavioral assessments and/or sociodemographic variables. For each assault incident, the chart of the patient who assaulted and a randomly chosen patient who did not assault on that day were reviewed (N = 72 subjects or 26 pairs). Various scales were used to evaluate the subjects retrospectively (the day prior to the assault), and patients who assaulted staff were interviewed when possible.

A metaanalysis of home uterine activity monitoring.

Objective: Our purpose was to assess by metaanalysis the evidence from randomized clinical trials regarding home uterine activity monitoring.

Study Design: Six randomized controlled trials of home uterine activity monitoring, the same six trials reviewed by the U.S.

Improved mortality and rehabilitation of transplant candidates treated with a long-term implantable left ventricular assist system.

Objective: This nonrandomized study using concurrent controls was performed to determine whether the HeartMate implantable pneumatic (IP) left ventricular assist system (LVAS) could provide sufficient hemodynamic support to allow rehabilitation of severely debilitated transplant candidates and to evaluate whether such support reduced mortality before and after transplantation.

Methods: Outcomes of 75 LVAS patients were compared with outcomes of 33 control patients (not treated with an LVAS) at 17 centers in the United States. All patients were transplant candidates who met the following hemodynamic criteria: pulmonary capillary wedge pressure > or = 20 mm Hg with a systolic blood pressure < or = 80 mm Hg or a cardiac index < or = 2.

Newborn acoustic cry characteristics of infants subsequently dying of sudden infant death syndrome.

Objective: To test the hypothesis that the occurrence of a neonatal cry exhibiting a high first formant is a risk factor for sudden infant death syndrome (SIDS) and to evaluate the association between SIDS and other acoustic cry variables.

Method: We recorded cries and obtained medical and demographic data for 21,880 apparently healthy term newborns. Two cries were recorded between days 2 and 7 of life, after a painful stimulus at the time of routine blood drawing.

Patient assault: a comparison of patient and staff perceptions.

The purpose of this study was to compare the perceptions of assaultive patients and staff victims regarding assault incidents. The hypotheses were as follows: (1) There will be congruence between patients' and victims' reports of objective or factual information regarding the assaults and (2) there will not be congruence between patients' and victims' reports of subjective information about the assaults. Monahan's (1981) framework was used for assessing violence on the assaultive patient and the assaulted staff member.

Predicting violence: nursing diagnosis versus psychiatric diagnosis.

Predicting violent behavior is a major concern for nurses as well as other mental health professionals. Two diagnostic assessment systems (Nursing Diagnosis-NANDA and Psychiatric Diagnosis-DSM III-R) were compared in their ability to predict assaultive behavior. The nursing diagnosis potential for violence suggested a difference (p = .

Environmental characteristics related to patient assault.

Environmental factors related to physical assault by patients were examined to identify clinical implications warranting further investigation and to test methodology. The concepts of ward conditions (degree of patients' illness, numbers of patients and staff) and ward climate were the focus of the study. Participants were patients and nursing staff on two acute and four long-term psychiatric units in a large neuropsychiatric hospital.

Polysymptomatic syndromes and autonomic reactivity to nonfood stressors in individuals with self-reported adverse food reactions.

This study compared symptom reports and cardiovascular reactivity of a group of 24 individuals recruited from the community who reported a cognitive or emotional symptom caused by at least one food (food-sensitivity reporters, FSR) vs those of 15 controls (C) without a history of food, chemical, drug, or inhalant sensitivities. The main findings were: 1) FSR indicated sensitivities not only to foods, but also to environmental chemicals, drugs, and natural inhalants, as well as significantly more symptoms than C in multiple systems; 2) more FSR than C noted recent state depression and anxiety, as well as higher trait anxiety on the Bendig form of the Taylor Manifest Anxiety Scale; 3) however, on multiple regression analysis, not only depression, but also the number of sensitivities (foods, chemicals, drugs, inhalants), accounted for part of the variance in total number of symptoms (38 and 17%, respectively), whereas none of the affective measures accounted for any of the variance in total number of sensitivities over all subjects; 4) after controlling for depression and anxiety, FSR still showed a trend toward poorer performance on a timed mental arithmetic task (p = 0.16); and 5) FSR and C showed opposite patterns of heart rate change to two different stressful tasks (mental arithmetic and isometric exercise) (group by task interaction, p < 0.

Plasma homocysteine in vascular disease and in nonvascular dementia of depressed elderly people.

Depression among elderly people with reversible cognitive loss often manifests with concomitant vascular disease and can also precede the development of nonvascular degenerative dementia. Little is known about etiological factors for reversible or irreversible dementias in older depressed people. The amino acid homocysteine (HC), which is both a vascular disease risk factor and a precursor of the excitotoxic amino acids cysteine and homocysteic acid, could play a role in the pathophysiology of such individuals.

Effects of in utero cocaine exposure on newborn acoustical cry characteristics.

As part of a large, multicenter study of newborn cry analysis and Sudden Infant Death Syndrome, we examined the effects of in utero cocaine exposure on ten acoustical cry characteristics. Newborn cry recording and medical record review was performed for 23,948 newborns. Cocaine use during pregnancy (determined by record review) was identified in 438 (1.

Brief communication. Vitamin B1, B2, and B6 augmentation of tricyclic antidepressant treatment in geriatric depression with cognitive dysfunction.

This was a 4-week randomized placebo-controlled double-blind study to assess augmentation of open tricyclic antidepressant treatment with 10 mg each of vitamins B1, B2, and B6 in 14 geriatric inpatients with depression. The active vitamin group demonstrated significantly better B2 and B6 status on enzyme activity coefficients and trends toward greater improvement in scores on ratings of depression and congnitive function, as well as in serum nortriptyline levels compared with placebo-treated subjects (Ss). Without specific supplementation, B12 levels increased in Ss receiving B1/B2/B6 and decreased in placebo Ss.

Abnormalities in color vision and contrast sensitivity in Parkinson's disease.

Dopamine is a neurotransmitter found in the retina. Delays in the visual evoked responses and abnormalities in contrast sensitivity occur in patients with Parkinson's disease. Improvement in the P100 has followed L-dopa therapy.

Multicenter randomized clinical trial of home uterine activity monitoring for detection of preterm labor.

Home uterine activity monitoring has been described as an effective means of detecting uterine contractions, but controversy exists whether it is home uterine activity monitoring or increased nursing support in conjunction with it that contributes to earlier detection of preterm labor. In this study 377 women at risk for preterm labor from three centers were prospectively, randomly assigned to high-risk prenatal care alone (not monitored) or to the same care with twice-daily home uterine activity monitoring without increased nursing support (monitored). The two groups were medically and demographically similar at entry into the study.

Nursing staff characteristics related to patient assault.

There is an underlying belief that there is something special about the victims of patient assault, that they possess certain characteristics or behave in a different way from those staff who are not assaulted. Is this a case of blaming the victims, or are there some actual differences between those staff members who are assaulted and those who are not? This study undertook this question. Its specific purpose was to (1) characterize staff victims and compare them to nonassaulted staff and (2) document outcomes on staff who were assaulted.

B complex vitamin patterns in geriatric and young adult inpatients with major depression.

This study compared the B complex vitamin status at time of admission of 20 geriatric and 16 young adult non-alcoholic inpatients with major depression. Twenty-eight percent of all subjects were deficient in B2 (riboflavin), B6 (pyridoxine), and/or B12 (cobalamin), but none in B1 (thiamine) or folate. The geriatric sample had significantly higher serum folate levels.

Relationship of normal serum vitamin B12 and folate levels to cognitive test performance in subtypes of geriatric major depression.

This retrospective study evaluated the relationships between normal serum vitamin B12 and folate levels and neuropsychologic measures in a sample of 60 geriatric inpatients with psychotic depression, nonpsychotic depression, bipolar disorder, and dementia--all consecutively referred for cognitive testing. The psychotic depression subgroup demonstrated numerous significant positive correlations between B12 and cognitive subtests not seen in other diagnostic subgroups, especially those of IQ, and verbal and visual memory. Metabolic factors including vitamin B12 may play specific roles in the cognitive dysfunctions of different geropsychiatric disorders.

School Breakfast Program and school performance.

To test the hypothesis that participation in the School Breakfast Program by low-income children is associated with improvements in standardized achievement test scores and in rates of absence and tardiness, children in grades 3 through 6 were studied in the Lawrence, Mass, public schools, where the School Breakfast Program was begun at the start of the second semester 1986-1987 school year. The changes in scores on a standardized achievement test and in rates of absence and tardiness before and after the implementation of the School Breakfast Program for children participating in the program were compared with those of children who also qualified but did not participate. Controlling for other factors, participation in the School Breakfast Program contributed positively to the 1987 Comprehensive Tests of Basic Skills battery total scale score and negatively to 1987 tardiness and absence rates.

Effects of maternal marijuana and cocaine use on fetal growth.

To investigate the effects on infants of the use of marijuana and cocaine during pregnancy and to compare the importance of urine assays with that of interviews in ascertaining drug use, we prospectively studied 1226 mothers, recruited from a general prenatal clinic, and their infants. On the basis of either interviews or urine assays conducted prenatally or post partum, 27 percent of the subjects had used marijuana during pregnancy and 18 percent had used cocaine. When only positive urine assays were considered, the corresponding values were 16 percent and 9 percent, respectively.

Cocaine use during pregnancy: prevalence and correlates.

Cocaine use during pregnancy was assessed by interviews and urine assays obtained prenatally and immediately postpartum from 679 urban women enrolled in prenatal care. Of these, 17% were found to have used cocaine at least once during pregnancy. Eight percent had urine assays positive for cocaine metabolites using the enzyme-mediated immunoassay technique with a cut-off of 300 ng/mL of benzoylecgonine.

Risk of sudden infant death syndrome among infants with in utero exposure to cocaine.

To determine whether the risk of sudden infant death syndrome (SIDS) among infants exposed to cocaine in utero may be elevated, we assessed the risk for SIDS in a large, well-described, prospective cohort of infants whose mothers had or had not used cocaine during pregnancy. Of 996 women consecutively enrolled while registering for prenatal care, 175 used cocaine during pregnancy. Only one infant of the mothers who used cocaine died of SIDS, a risk of 5.

Why adolescents do not attend school. The views of students and parents.

Despite the magnitude and importance of the problem, little is known about why many students are absent from school. This study assessed what a sample of excessively absent students and their parents believed were the reasons for the students' absences. In response to an open-ended question about their main reason for absence, almost half of the students reported a health-related reason.

Survival of patients with primary (AL) amyloidosis. Colchicine-treated cases from 1976 to 1983 compared with cases seen in previous years (1961 to 1973).

Primary amyloidosis has a variable course, but is generally associated with a short life expectancy. To date, no specific therapy has been available. Fifty-three patients with AL amyloidosis seen between 1976 and 1983 were treated with colchicine, and their clinical course and survival were compared with that in 29 other patients seen between 1961 and 1973.
