Early paternal retrieval experience influences the degree of maternal retrieval behavior in adult California mice offspring

In biparental species like the California mouse (Peromyscus californicus), paternal presence and care contributes to offspring survival with lasting consequences on brain development and social behavior. Paternal retrieval behavior may be particularly important since it protects young from dangers outside of the nest. We have previously shown that paternal retrievals influence social behavior of adult female and male offspring, as well as the expression of hormones associated with parental behavior. In male offspring, paternal retrieval influences future parenting, but whether paternal retrievals affect maternal behavior in adulthood is unclear. Here, we manipulated the experience of paternal retrieval during development and then assessed maternal behavior of adult female offspring. We did not detect group differences in maternal behavior during undisturbed observation or following pup displacement. However, following pup displacement we observed a moderate positive correlation between paternal retrievals experienced in development and maternal retrievals performed in adulthood. Further analysis revealed that the likelihood of females being a high or low retriever is influenced by their developmental experience. These findings suggest that although female California mice engage in similar levels of maternal behavior regardless of paternal care environment, there may be variation in retrieval behavior that is informed by paternal retrieval experience.

Relation of Mental Health to Alcohol and Substance Use Among Texas College Students

We examined the effect of mental health problems and difficulties on alcohol, tobacco, and other drug (ATOD) use among college students by using the 2013 Texas College Survey of Substance Use (n=11,216), which includes the K6 screening scale for severe mental illness (SMI). Students' K6 scores were used to classify them into 3 groups: those likely to have SMI (9% with scores ≥ 13), those with some mental health problems (36%), and those without mental health issues (55% with scores ≤ 4). Questions regarding ATOD use were analyzed using these 3 groups. Alcohol use was not significantly associated with K6 scores, although problematic alcohol behaviors as measured by the CAGE test were. Higher cigarette use was significantly associated with higher K6 scores. Finally, both higher marijuana and higher drug use (across 9 other individual drugs) were significantly associated with higher K6 scores. Although higher K6 scores were associated with higher rates of drug use, most students with high K6 scores did not use drugs. However, given the higher level of risk, drug and alcohol interventions should be made available for those students who receive mental health counseling.

Mental Health Services in Texas Jails

Jails and prisons in the United States have become the places where people with mental illness go. Texas jails were surveyed in 2012 to learn how they screened inmates for mental illness. Of these jails, 13% responded. Most screened for suicidal ideation and whether or not an inmate took a medicine. About half the jails offered in-house care, and the other half referred inmates to the local mental health authority. Most jails had a formal jail diversion program, and most thought that mental health illness was increasing. About half had an annual 4-hour training program for staff. Recommendations are made for future care in jails.

Causes of death and comparative mortality in Texas public mental health clients, 2006–2008

Seriously mentally ill patients are known to have rates of mortality much greater than those of the general population. Prior research in Texas has shown inpatient Public Mental Health Clients (PMHCs) treated in in-patient settings were subject to greatly increased mortality, but little is known about the mortality of PMHCs in an outpatient setting in Texas.

For this study outpatient service records for PMHCs treated in Texas were combined with death data from the Texas Department of State Health Services for 2006–2008. Frequencies of causes of death, age-adjusted death rates, standardized mortality ratios, and life expectancies were calculated from these data.

The most frequent causes of death were external causes, followed by circulatory disease, and then neoplasms. Examination of the outcomes suggests that substance abuse plays a major role in the mortality of PMHCs in Texas in the form of drug overdoses, tobacco-related cancers, and alcoholic liver disease. Prevention efforts should therefore aim at integrating mental health services, substance abuse services, and careful medical and pharmacological monitoring, including medication monitoring to prevent suicides and accidental overdoses.

Assessing the risk of ships striking large whales in marine spatial planning

Marine spatial planning provides a comprehensive framework for managing multiple uses of the marine environment and has the potential to minimize environmental impacts and reduce conflicts among users. Spatially explicit assessments of the risks to key marine species from human activities are a requirement of marine spatial planning. We assessed the risk of ships striking humpback (Megaptera novaeangliae), blue (Balaenoptera musculus), and fin (Balaenoptera physalus) whales in alternative shipping routes derived from patterns of shipping traffic off Southern California (U.S.A.). Specifically, we developed whale-habitat models and assumed ship-strike risk for the alternative shipping routes was proportional to the number of whales predicted by the models to occur within each route. This definition of risk assumes all ships travel within a single route. We also calculated risk assuming ships travel via multiple routes. We estimated the potential for conflict between shipping and other uses (military training and fishing) due to overlap with the routes. We also estimated the overlap between shipping routes and protected areas. The route with the lowest risk for humpback whales had the highest risk for fin whales and vice versa. Risk to both species may be ameliorated by creating a new route south of the northern Channel Islands and spreading traffic between this new route and the existing route in the Santa Barbara Channel. Creating a longer route may reduce the overlap between shipping and other uses by concentrating shipping traffic. Blue whales are distributed more evenly across our study area than humpback and fin whales; thus, risk could not be ameliorated by concentrating shipping traffic in any of the routes we considered. Reducing ship-strike risk for blue whales may be necessary because our estimate of the potential number of strikes suggests that they are likely to exceed allowable levels of anthropogenic impacts established under U.S. laws.

General medical care external hospitalizations for patients in Texas state mental health hospitals

We explored the characteristics of general medical hospital admissions for patients in state mental health hospitals. Data were extracted from a statewide database of all hospital discharges for 5 years identified as general medical hospital admissions that occurred during the stay of patients at state mental health hospitals. Across the 9 mental health hospitals in the state system, rates of admission to general medical hospitals varied significantly from 0.7% to 3.7%. On average, of the 1.9% of all state mental health inpatients who had a general hospital admission, 25% occurred within 4 days of admission to the mental hospital. The average general hospitalization lasted 5.7 days. The reported total charge for all stays was $34 million. Dehydration (15%), hypertension (10%), and diabetes (10%) were the most frequent diagnoses. Thirteen percent of diagnoses met preventable hospitalization criteria. Given the variability among hospitals in admission rates and the number of preventable conditions, improvements in patient care and health as well as reduced admissions to general medical hospitals may be possible.

Association between depressed mood and perceived weight in middle and high school age students: Texas 2004-2005

Research exploring the relationship between weight perception and depressed mood among adolescents is limited in the United States. The purpose of this study is to examine the association of perceived versus actual body weight and depressed mood in a representative sample of 8th and 11th grade public school students in Texas. Using data from the 2004-2005 School Physical Activity and Nutrition (SPAN) study, logistic regression analyses were conducted to assess the association of weight perception with depressed mood. Healthy weight students who perceived themselves to be a healthy weight were the reference group for all analyses. A high prevalence of misperception of body weight was observed. Overweight and obese 8th grade girls and boys who perceived themselves to be overweight had increased odds of depressed mood [Girls: OR 1.70 (95% CI: 1.07-2.69), Boys: OR 2.05 (95% CI: 1.16-3.62)]. Healthy weight 8th grade girls who perceived themselves to be overweight had 2.5 times greater odds of depressed mood (OR 2.63, 95% CI: 1.54-4.50). Healthy weight boys who perceived themselves to be underweight had more than twice the odds (OR 2.18, 95% CI: 1.23-3.89) of depressed mood. No weight category was significantly associated with depressed mood in boys or girls in 11th grade. The present study suggests that weight misperceptions are associated with depressed mood in young adolescents. Education about healthy body size is necessary to correct the common weight misperceptions observed. The high prevalence rates of depressed mood suggest a greater need for research into understanding factors that may contribute to depressed mood in adolescents.

Shortage of child and adolescent psychiatrists in Texas

This study was conducted to determine how the current shortage of Texas child and adolescent psychiatrists (CAPs) impacts the delivery of mental health care services to indigent Texas youth. First, Texas Medical Board data detailed how many counties had CAPs and how many did not. Second, statewide Medicaid data revealed the number of prescriptions for psychotropics written for Medicaid youth by CAPs and non-CAPs. Third, Local Mental Health Authority (LMHA) encounter data of youth seen by a CAP were analyzed. Fourth, state census data gave the location and characteristics of youth by county. Eighty percent of counties in Texas, predominantly rural, do not have a CAP. Non-CAPs wrote 66% of psychotropic medication prescriptions written for Medicaid youth. Those in nonmetropolitan areas were more likely to see a non-CAP than were Medicaid youth in metropolitan areas. For youth seen by an LMHA, those in rural poor counties were less likely to see a CAP than were those in urban counties. The shortage of CAPs in Texas results in an unequal distribution of psychiatric care for those receiving Medicaid prescriptions or services through LMHAs, especially in rural areas. Suggestions to correct this shortage are made.

SSRI Use and Behavioral Disruption Among Children and Adolescents at Austin State Hospital

This study examined the effect of selective serotonin reuptake inhibitors (SSRIs) on children and adolescents' disruptive behavior. Administrative data were obtained for 1 year of child and adolescent admissions at Austin State Hospital. Two measures of disruptive behavior were operationally defined as the use of mechanical restraints and emergency medication. Between-subjects analysis compared patients who did versus those who did not receive SSRIs. Within-subject analysis was conducted only for patients receiving SSRIs to examine their disruptive behavior during medication initiation. No differences were found between patients who did versus those who did not receive SSRIs. No differences were found among patients who received SSRIs during initial versus later phases of drug use. No significant relationship between SSRI use and increased agitation, hostility, or self-harm as manifested by the number of mechanical restraints or emergency medications at any time during hospitalization was found.
