Objective:
Repetitive transcranial magnetic stimulation (TMS) is an evidenced based treatment for adults with treatment resistant depression (TRD). The standard clinical protocol for TMS is to stimulate the left dorsolateral prefrontal cortex (DLPFC). Although the DLPFC is a defining region in the cognitive control network of the brain and implicated in executive functions such as attention and working memory, we lack knowledge about whether TMS improves cognitive function independent of depression symptoms. This exploratory analysis sought to address this gap in knowledge by assessing changes in attention before and after completion of a standard treatment with TMS in Veterans with TRD.
Participants and Methods:Participants consisted of 7 Veterans (14.3% female; age M = 46.14, SD = 7.15; years education M = 16.86, SD = 3.02) who completed a full 30-session course of TMS treatment and had significant depressive symptoms at baseline (Patient Health Questionnaire-9; PHQ-9 score >5). Participants were given neurocognitive assessments measuring aspects of attention [Wechsler Adult Intelligence Scale 4th Edition (WAIS-IV) subtests: Digits Forward, Digits Backward, and Number Sequencing) at baseline and again after completion of TMS treatment. The relationship between pre and post scores were examined using paired-samples t-test for continuous variables and a linear regression to covary for depression and posttraumatic stress disorder (PTSD), which is often comorbid with depression in Veteran populations.
Results:There was a significant improvement in Digit Span Forward (p=.01, d=-.53), but not Digit Span Backward (p=.06) and Number Sequencing (p=.54) post-TMS treatment. Depression severity was not a significant predictor of performance on Digit Span Forward (f(1,5)=.29, p=.61) after TMS treatment. PTSD severity was also not a significant predictor of performance on Digit Span Forward (f(1,5)=1.31, p=.32).
Conclusions:Findings suggested that a standard course of TMS improves less demanding measures of working memory after a full course of TMS, but possibly not the more demanding aspects of working memory. This improvement in cognitive function was independent of improvements in depression and PTSD symptoms. Further investigation in a larger sample and with direct neuroimaging measures of cognitive function is warranted.

The prolific seed production and polyploidy of annual bluegrass allow for the rapid development of herbicide resistance. Ethofumesate-resistant annual bluegrass plants were identified in the 1990s in grass seed production in Oregon, but their prevalence and distribution are not well documented. Therefore a dose–response experiment was initiated to determine the potential level of ethofumesate resistance in seed production systems. Seeds from 55 annual bluegrass populations were obtained from three sources: seed production fields (31 populations), the seed cleaning process (6 populations), and seed testing lots prior to retail distribution (18 populations). Additionally, two populations, one with known ethofumesate resistance and one with known susceptibility, were identified in preliminary testing and used as controls in this experiment. Seed from each collected population was increased. Individual seedlings were then transplanted into separate cone-tainers, grown to a size of 2 to 3 tillers in the greenhouse, and then sprayed using a compressed air track spray chamber with 10 doses of ethofumesate at 0, 0.56, 1.1, 2.8, 5.6, 8.4, 11.2, 16.8, 22.4, and 44.8 kg ai ha−1, with 0.84 to 2.2 kg ha−1 as the label application rate for perennial ryegrass. The resistant to susceptible ratio of populations across all sources ranged from 0.5 to 5.5. The most resistant populations found in production fields, seed cleaning, and seed testing lots had the effective dose necessary to kill 50% of the population (ED50) of 12.1, 9.4, and 13.1 kg ha−1, respectively. Furthermore, 68% of the populations found in production fields had ED50 higher than 6 kg ha−1, indicating common annual bluegrass resistance in grass seed production. As such, growers should implement integrated weed management strategies, as herbicides alone will likely be ineffective at controlling annual bluegrass.

Background
Episodes of acute agitation can occur in individuals who suffer from schizophrenia or bipolar disorder and these can be a significant challenge for patients and for those who provide care to them. Sublingual dexmedetomidine is a selective alpha2-adrenergic receptor agonist that was recently approved by the US Food and Drug Administration for the treatment of agitation in adults with schizophrenia or bipolar disorder. The sublingual form of dexmedetomidine does not undergo first-pass hepatic metabolism, thus resulting in greater absorption than when ingested. In two Phase 3 studies of adults with schizophrenia or bipolar disorder, sublingual dexmedetomidine significantly reduced acute agitation at 2 hours, as measured by the five-item Positive and Negative Syndrome Scale-Excited Component (PEC). When initially appraising the potential utility of a new medication, number needed to treat (NNT) and needed to harm (NNH) can be helpful to assess the size of the treatment effect and, hence, clinical relevance.
ObjectiveCalculation of NNT and NNH through post hoc analysis of Phase 3 data.
MethodsPost hoc analysis of data were performed on data from two double-blind, randomized, placebo-controlled studies of sublingual dexmedetomidine in adults with schizophrenia or bipolar disorder experiencing acute agitation. Patients were randomized to a single dose of sublingual dexmedetomidine 180 μg, 120 μg, or placebo. The primary endpoint was mean change from baseline in the PEC total score. A therapeutic response was defined as a ≥40% reduction from baseline in PEC total score at 2 hours. NNT was calculated for PEC response rate for sublingual dexmedetomidine versus placebo. NNH was calculated using the incidence of adverse events for sublingual dexmedetomidine versus placebo. Likelihood to be helped or harmed (LHH) was calculated as the ratio of NNH to NNT.
ResultsNNT (95% CI) was 3 (2, 3) for 180 mcg and 3 (3, 4) for 120 ug in patients with schizophrenia and 3 (2, 3) for 180 mcg and 4 (3, 6) for 120 ug in patients with bipolar disorder. NNH was greater than 10 for all AEs except somnolence, where NNH was 7 (5, 10) for all doses pooled from both studies. LLH values were greater than 1 for efficacy versus applicable tolerability outcomes in all cases.
ConclusionsThis post hoc analysis demonstrated favorable NNT and NNH values for sublingual dexmedetomidine. In all instances therapeutic response was encountered more frequently than any adverse event. These values compare favorably to similar analyses for other approved agents for the treatment of agitation associated with schizophrenia or bipolar disorder, including intramuscular and inhaled formulations.

Food insecurity on college campuses is a major public health problem and has been documented for the last decade. Sufficient food access is a crucial social determinant of health, thus campuses across the country have implemented various programmes, systems and policies to enhance access to food which have included food pantries, campus gardens, farmers’ markets, meal share or voucher programmes, mobile food applications, campus food gleaning, food recovery efforts, meal deliveries and task force/working groups. However, little is understood about how to best address food insecurity and support students who are struggling with basic needs. The impact of food insecurity on students’ academic and social success, in addition to their overall well-being, should be investigated and prioritised at each higher education institution. This is especially true for marginalised students, such as minority or first-generation students, who are at heightened risk for food insecurity. In order to create a culture of health equity, in which most at-risk students are provided resources and opportunities to achieve optimal well-being, higher education institutions must prioritise mitigating food insecurity on the college campus. Higher education institutions could benefit from adopting comprehensive and individualised approaches to promoting food security for marginalised students in order to facilitate equal opportunity for optimal scholastic achievement among students of all socio-demographic backgrounds.

Objective:
To describe the genomic analysis and epidemiologic response related to a slow and prolonged methicillin-resistant Staphylococcus aureus (MRSA) outbreak.
Design:Prospective observational study.
Setting:Neonatal intensive care unit (NICU).
Methods:We conducted an epidemiologic investigation of a NICU MRSA outbreak involving serial baby and staff screening to identify opportunities for decolonization. Whole-genome sequencing was performed on MRSA isolates.
Results:A NICU with excellent hand hygiene compliance and longstanding minimal healthcare-associated infections experienced an MRSA outbreak involving 15 babies and 6 healthcare personnel (HCP). In total, 12 cases occurred slowly over a 1-year period (mean, 30.7 days apart) followed by 3 additional cases 7 months later. Multiple progressive infection prevention interventions were implemented, including contact precautions and cohorting of MRSA-positive babies, hand hygiene observers, enhanced environmental cleaning, screening of babies and staff, and decolonization of carriers. Only decolonization of HCP found to be persistent carriers of MRSA was successful in stopping transmission and ending the outbreak. Genomic analyses identified bidirectional transmission between babies and HCP during the outbreak.
Conclusions:In comparison to fast outbreaks, outbreaks that are “slow and sustained” may be more common to units with strong existing infection prevention practices such that a series of breaches have to align to result in a case. We identified a slow outbreak that persisted among staff and babies and was only stopped by identifying and decolonizing persistent MRSA carriage among staff. A repeated decolonization regimen was successful in allowing previously persistent carriers to safely continue work duties.

ABSTRACT IMPACT: Being explicit about the prevention of falls throughout an older adults’ episode of care may further help reinforce the role of physical therapy providers in falls prevention and improve dissemination of this knowledge. OBJECTIVES/GOALS: The purpose of this study was to determine older adults’ awareness of and perspectives about the role of physical therapy providers for falls prevention and determine potential barriers and facilitators to utilization of preventive rehabilitation services METHODS/STUDY POPULATION: We used a qualitative descriptive phenomenological approach to emphasize participants’ perceptions and lived experiences. Four focus groups were conducted with 27 community-dwelling older adults (average age = 78 years). Focus groups were recorded, transcribed, condensed, and coded using thematic analysis. RESULTS/ANTICIPATED RESULTS: Surveys indicated 37% of participants experienced a fall in the last year and 26% reported suffering an injury. Four main themes and six subthemes surrounding older adults’ perceptions of physical therapy providers’ roles for falls prevention emerged: (1) Awareness of Falls Prevention (subthemes: I Don’t Think About It, I Am More Careful); (2) Being Able to Get Up from the Floor; (3) Limited Knowledge about the Role of Physical Therapy Providers in Falls Prevention (subtheme: Physical Therapy Services are for After a Fall, Surgery, or for a Specific Problem); and 4). Barriers to Participating in Preventive Physical Therapy Services (subthemes: Perceived Need and Costs, Access Requires a Doctor’s Prescription). DISCUSSION/SIGNIFICANCE OF FINDINGS: Older adults lack awareness about the role of physical therapy services in falls prevention, perceiving services are only to treat a specific problem or after a fall. Physical therapists should be explicit about the role of physical therapy in falls prevention for all older adults undergoing rehabilitation, regardless of the reason.

In order to expedite the study of the effects of various biologically active chemicals upon the blood cells of insects a rapid clinical type method was needed that would allow preparations to be made with small (1 microliter or less) samples of blood which could be drawn without sacrificing the insect, and could be fixed and stained quickly for examination. A method meeting these requirements for the study of the blood cells of the American and German cockroaches has been developed.

Galaxy-galaxy interactions and large scale galaxy bars are usually considered as the two main mechanisms for driving gas to the centres of galaxies. By using large samples of galaxy pairs and visually classified bars from the Sloan Digital Sky Survey (SDSS), we compare the relative efficiency of gas inflows from these two processes. We use two indicators of gas inflow: star formation rate (SFR) and gas phase metallicity, which are both measured relative to control samples. Whereas the metallicity of galaxy pairs is suppressed relative to its control sample of isolated galaxies, galaxies with bars are metal-rich for their stellar mass by 0.06 dex over all stellar masses. The SFRs of both the close galaxy pairs and the barred galaxies are enhanced by ~60%, but in the bars the enhancement is only seen at stellar masses M∗ > 1010 M⊙. Taking into account the relative frequency of bars and pairs, we estimate that at least three times more central star formation is triggered by bars than by interactions.

Repeated neuropsychological assessments are common with older adults, and the determination of clinically significant change across time is an important issue. Regression-based prediction formulas have been utilized with other patient and healthy control samples to predict follow-up test performance based on initial performance and demographic variables. Comparisons between predicted and observed follow-up performances can assist clinicians in determining the significance of change in the individual patient. In the current study, multiple regression-based prediction equations for the 5 Indexes and Total Score of the RBANS were developed for a sample of 223 community dwelling older adults. These algorithms were then validated on a separate elderly sample (N = 222). Minimal differences were present between observed and predicted follow-up scores in the validation sample, suggesting that the prediction formulas are clinically useful for practitioners who assess older adults. A case example is presented that illustrates how the algorithms can be used clinically. (JINS, 2004, 10, 828–834.)
