Proactive aggression: A two part study

Aggressive behavior can be divided into the subtypes: reactive and proactive. Reactive aggressive acts occur in response to a stimulus or provocation. Proactive aggressive acts occur without provocation and are goal-directed. A number of findings have suggested that individuals displaying proactive aggression may be discerned from individuals not displaying proactive aggression on measures of personality, psychopathology and psychopathy, as well as on aggressive histories and type and severity of aggressive behaviors committed. The current study was conducted in two phases; phase 1 and 2. This was because phase 1 compared proactive aggressive, reactive aggressive and non-aggressive subjects on questionnaire measures, while phase 2 observed the acute effects of the benzodiazepine alprazolam on only proactive aggressive subjects. The phase 1 hypotheses were that proactive aggressive subjects would show greater numbers of personality disorders and have greater psychopathy relative to reactive and non-aggressive subjects. To verify these hypotheses subjects were recruited from the community and classified as proactive (n = 20), reactive (n = 20) or non-aggressive (n = 10) via laboratory behavioral testing. Classified subjects were administered a battery of questionnaires pertaining to personality disorders (SCID-II, OMNI-IV), psychopathy (PCL-R) and aggression history. The results of these questionnaire measures were subjected to statistical analyses, which confirmed the hypotheses. In the second phase, the acute effects of three doses of the benzodiazepine alprazolam were evaluated in proactive aggressive subjects on proactive aggressive responding in the computer-based Point Subtraction Aggression Paradigm (PSAP). In phase 2 it was hypothesized that alprazolam would produce dose dependent decreases in aggressive responding. Subjects were never provoked in this phase, and aggressive responding was classified as proactive. Studies of drugs acting on the GABA system have frequently found decreases in aggression in animals and humans, although there have also been findings of increased (paradoxical) aggression. The hypothesis was tested by statistical analysis of proactive aggressive responding under placebo vs. under alprazolam. The hypothesis was supported by six of seven subjects. Aggressive responding was significantly, decreased under alprazolam relative to placebo in six subjects. One subject showed increases in aggressive responding.^

Establishing occupational and environmental health design requirements for Lunar and Mars settlements

In a study of Lunar and Mars settlement concepts, an analysis was made of fundamental design assumptions in five technical areas against a model list of occupational and environmental health concerns. The technical areas included the proposed science projects to be supported, habitat and construction issues, closed ecosystem issues, the "MMM" issues--mining, material-processing, and manufacturing, and the human elements of physiology, behavior and mission approach. Four major lessons were learned. First it is possible to relate public health concerns to complex technological development in a proactive design mode, which has the potential for long-term cost savings. Second, it became very apparent that prior to committing any nation or international group to spending the billions to start and complete a lunar settlement, over the next century, that a significantly different approach must be taken from those previously proposed, to solve the closed ecosystem and "MMM" problems. Third, it also appears that the health concerns and technology issues to be addressed for human exploration into space are fundamentally those to be solved for human habitation of the earth (as a closed ecosystem) in the 21st century. Finally, it is proposed that ecosystem design modeling must develop new tools, based on probabilistic models as a step up from closed circuit models. ^

Deployed military women: A second look at gender-specific infections

This descriptive, cross-sectional study addressed the relationship between variables of deployed military women and prevalence of gender-specific infections. The analysis of secondary data will look at the last deployment experience of 880 randomly selected U.S. military women who completed a mailed questionnaire (Deployed Female Health Practice Questionnaire (FHPQ)) in June 1998. The questionnaire contained 191 items with 80 data elements and one page for the subject's written comments. The broad categories of the questionnaire included: health practices, health promotion, disease prevention and treatment, reproduction, lifestyle management, military characteristics and demographics. The research questions are: (1) What is the prevalence of sexually transmitted diseases (STD), urinary tract infections (UTI) and vaginal infections (VI) related to demographic data, military characteristics, behavioral risk factors and health practices of military women during their last deployment? and (2) What are the differences between STD, UTI and VI related to the demographic data, military characteristics, behavioral risk factors and health practices of military women during their last deployment. The results showed that (1) STDs were found to be significantly associated with age and rank but not location of deployment or military branch; (2) UTI were found to be significantly associated with intrauterine device (IUD) use, prior UTI and type of items used for menses management, but not education or age; and (3) VI were significantly associated with age, rank and deployment location but not ethnicity or education. Although quantitative research exploring hygiene needs of deployed women continues, qualitative studies may uncover further “hidden” issues of importance. It cannot be said that the military has not made proactive changes for women, however, continued efforts to hone these changes are still encouraged. Mandatory debriefings of “seasoned” deployed women soldiers and their experiences would benefit leadership and newly deployed female soldiers with valuable “lessons learned.” Tailored hygiene education material, prevention education classes, easy access website with self-care algorithms, pre-deployment physicals, revision of military protocols for health care providers related to screening, diagnosing and treatment of gender-specific infections and process changes in military supply network of hygiene items for women are offered as recommendations. ^

Policy implications of public health workforce development for disaster preparedness in the United States

Public health efforts were initiated in the United States with legislative actions for enhancing food safety and ensuring pure drinking water. Some additional policy initiatives during the early 20th century helped organize and coordinate relief efforts for victims of natural disasters. By 1950's the federal government expanded its role for providing better health and safety to the communities, and its disaster relief activities became more structured. A rise in terrorism related incidents during the late 1990's prompted new proactive policy directions. The traditional policy and program efforts for rescue, recovery, and relief measures changed focus to include disaster preparedness and countermeasures against terrorism.^ The study took a holistic approach by analyzing all major disaster related policies and programs, in regard to their structure, process, and outcome. Study determined that United States has a strong disaster preparedness agenda and appropriate programs are in place with adequate policy support, and the country is prepared to meet all possible security challenges that may arise in the future. The man-made disaster of September 11th gave a major thrust to improve security and enhance preparedness of the country. These new efforts required large additional funding from the federal government. Most existing preparedness programs at the local and national levels are run with federal funds which is insufficient in some cases. This discrepancy arises from the fact that federal funding for disaster preparedness programs at present are not allocated by the level of risks to individual states or according to the risks that can be assigned to critical infrastructures across the country. However, the increased role of the federal government in public health affairs of the states is unusual, and opposed to the spirit of our constitution where sovereignty is equally divided between the federal government and the states. There is also shortage of manpower in public health to engage in disaster preparedness activities, despite some remarkable progress following the September 11th disaster.^ Study found that there was a significant improvement in knowledge and limited number of studies showed improvement of skills, increase in confidence and improvement in message-mapping. Among healthcare and allied healthcare professionals, short-term training on disaster preparedness increased knowledge and improved personal protective equipment use with some limited improvement in confidence and skills. However, due to the heterogeneity of these studies, the results and interpretation of this systematic review may be interpreted with caution.^

Hospital district viability and Medicaid /market changes

Hospital districts (HD) that serve the uninsured and the needy face new challenges with the implementation of Medicaid managed. The potential loss of Medicaid patients and revenues may affect the ability to cost-shift and subsequently decrease the ability of the HD to meet its legal obligation of providing care for the uninsured. ^ To investigate HD viability in the current market, the aims of this study were to: (1) describe HD's environment, (2) document the HDs strategic response, (3) document changes in the HD's performance (patient volume) and financial status, and (4) determine whether relationships or trends exist between HD strategy, performance and financial status. ^ To achieve these aims, three Texas HDs (Fort Worth, Lubbock, and San Antonio) were selected to be evaluated. For each HD four types of strategic responses were documented and evaluated for change. In addition, the ability of each HD to sustain operations was evaluated by documenting performance and financial status changes (patient volume and financial ratios). A pre-post case study design method was used in which the Medicaid managed care “rollout'” date, at each site, was the central date. First, a descriptive analysis was performed which documented the environment, strategy, financial status, and patient volume of each hospital district. Second, to compare hospital districts, each hospital district was: (i) classified by a risk index, (ii) classified by its strategic response profile, and (iii) given a performance score based upon pre-post changes in patient volume and financial indicators. ^ Results indicated that all three HDs operate in a high risk environment compared to the rest of the nation. Two HDs chose the “Status Quo” response whereas one HD chose the “Competitive Proactive” response. Medicaid patient volume decreased in two of three HDs whereas indigent patient volume increased in two of the three (an indication of increasing financial risk). Total patient revenues for all HDs increased over the study period; however, the rate of increase slowed for all three after the Medicaid rollout date. All HDs experienced a decline in financial status between pre-post periods with the greatest decline observed in the HD that saw the greatest increase in indigent patient volume. ^ The pre-post case study format used and the lack of control study sites do not allow for assignment of causality. However, the results suggest possible adverse effects of Medicaid managed care and the need for a larger study, based on a stronger evaluation research design. ^
