Predictors of Osprey Nest Success In A Highly Urbanized Environment

ABSTRACT Ospreys (Pandion haliaetus) are adaptable fish-eating raptors that readily nest on artificial structures in heavily human-dominated areas. Although the Osprey is a well-studied species, few researchers have investigated the factors that influence nest success and productivity in an urban environment. We monitored Osprey nests from 2013 to 2017 in highly urbanized Pinellas County, located on the west coast of central Florida, USA. We used logistic exposure models to assess the effects of timing of nesting, nest attributes (nest substrate, height), and landscape-level variables (inter-nest distance, distance to water, and surrounding habitat type) on daily survival rate (DSR) of Osprey nests. The number of active nests (i.e., nests with eggs) in the study area ranged from 53 in 2013 to 79 in 2016, with an overall total of 329 during the 5-yr study. Although most nests produced at least one young near fledging age, 131 of the nests failed. We attributed 45% of nest failures to storm events and 50% to unknown causes. The best logistic exposure model specification included only two variables: the discrete variable representing the date incubation started and the nominal variable indicating the year 2015. Osprey nests initiated earlier in the season were more likely to survive, and later nests (initiated after 22 April) averaged only one fledgling each. Osprey nests in 2015 had the highest DSR and relatively few failed due to storms. Our results supported previous research indicating that early nesters were more successful than late nesters. Our results also indicate that storms may play a role in nest success of Ospreys in Florida. Other variables, such as the amount of urbanized land surrounding Osprey nests did not appear to influence nest survival, indicating that Ospreys can be productive even in highly urban environments.

Another new exotic bark beetle in Florida: Ernoporus parvulus (Eggers, 1943) (Coleoptera: Curculionidae: Scolytinae), with additional taxonomic changes

The bark beetle, Ernoporus parvulus (Eggers, 1943) was collected from Pinellas County, Florida, USA representing the first North American record of the genus. Two species previously described from the Caribbean were examined and are synonymous: Ernoporus minutus (Bright & Torres, 2006) syn. nov. and E. exquisitus (Bright, 2019) syn. nov. This beetle is likely an overlooked exotic from Africa, known only from sea hibiscus, Talipariti tiliaceum (L.) Fryxell (Malvaceae). There is no evidence that this is a threat to commercial or ornamental Hibiscus and related species.

Concentrations of para-Fluorofuranylfentanyl (FFF) in Paired Central and Peripheral Blood Collected During Postmortem Death Investigations

The opioid epidemic in the United States (U.S.) has been associated with an increasing mortality rate in large part due to the emergence and proliferation of synthetic opioids over the last fifteen years. Fentanyl and its analogues have played a large part in these statistics due to their potency and toxicity. Fluorofuranylfentanyl (FFF) is a fentanyl analogue that emerged in the U.S. in 2018 and was associated with numerous adverse events and deaths. During this study, a liquid chromatography tandem mass spectrometry (LC-MS/MS) workflow was developed to accurately identify the isomer of FFF present (ortho- vs. meta- vs. para-) in medicolegal death investigation cases from Pinellas County, Florida. FFF was quantified in central and peripheral blood samples collected at autopsy. In addition, the metabolism of FFF was studied using liquid chromatography quadrupole time-of-flight mass spectrometry (LC-QTOF-MS). para-FFF was quantitatively confirmed in 29 postmortem cases; no other isomer of FFF was detected. Central blood concentrations ranged between 0.66 and 73 ng/mL (mean = 11±14 ng/mL, median = 10 ng/mL) and peripheral blood concentrations ranged between 0.53 and 23 ng/mL (mean = 5.7±6.4 ng/mL, median = 2.7 ng/mL). Comparison of central to peripheral blood concentrations were evaluated to determine the possibility of postmortem redistribution (PMR). The metabolism of ortho-FFF was studied and found to undergo metabolic processes similar to fentanyl, producing ortho-fluorofuranyl-norfentanyl, fluoro-4-ANPP, and hydroxylated species. The results of this study demonstrate the toxicity of FFF and its implication in medicolegal death investigations. Laboratories must remain aware of new or re-emerging fentanyl analogues, as they pose significant risks to public health and public safety.

Structured Telephone Support Intervention: Improved Heart Failure Outcomes

Background Presently, 6.5 million Americans are living with heart failure (HF). These patients are expected to follow a complex self-management regimen at home. Several demographic and psychosocial factors limit patients with HF in following the prescribed self-management recommendations at home. Poor self-care is associated with increased hospital re-admissions. Under the Affordable Care Act, there are financial implications related to hospital re-admissions for hospitals and programs such as the Program of All-Inclusive Care for the Elderly (PACE) in Pinellas County, Florida. Previous studies and systematic reviews demonstrated improvement in self-management and quality of life (QoL) in patients with HF with structured telephone support (STS) and short message service text messaging (SMS). Objective This study aimed to evaluate the effects of STS and SMS on self-care, knowledge, medication adherence, and QoL of patients with HF. Methods A prospective quality improvement project using a pre-post design was implemented. Data were collected at baseline, 30 days, and 3 months from 51 patients with HF who were enrolled in PACE in Pinellas County, Florida. All participants received STS and SMS for 30 days. The feasibility and sustained benefit of using STS and SMS was assessed at a 3-month follow-up. Results A paired t test was used to compare the mean difference in HF outcomes at the baseline and 30-day follow-up, which demonstrated improved HF self-care maintenance (t49=0.66; P=.01), HF knowledge (t49=0.71; P=.01), medication adherence (t49=0.92; P=.01), and physical and mental health measured using Short-Form-12 (SF-12; t49=0.81; P=.01). The results also demonstrated the sustained benefit with improved HF self-care maintenance, self-care management, self-care confidence, knowledge, medication adherence, and physical and mental health (SF-12) at 3 months with P<.05 for all outcomes. Living status and social support had a strong correlation with HF outcomes. Younger participants (aged less than 65 years) performed extremely well compared with older adults. Conclusions STS and SMS were feasible to use among PACE participants with sustained benefits at 3 months. Implementing STS and SMS may serve as viable options to improve HF outcomes. Improving outcomes with HF affects hospital systems and the agencies that monitor and provide care for outpatients and those in independent or assisted-living facilities. Investigating viable options and support for implementation will improve outcomes.

A Dual-Pronged Approach to Improving Heart Failure Outcomes: A Quality Improvement Project (Preprint)

BACKGROUND Presently, 6.5 million Americans are living with heart failure (HF). These patients are expected to follow a complex self-management regimen at home.
